AI Biases – Their Effects with Real-world cases

Back After a long.. Today, I’m back with a journey to unravel the intricacies of biases in one of the trending topics, artificial intelligence (AI)!

I had no idea that watching the most recent episode of “Ani Aba with Dr. Bibek Paudel and Sudheer Sharma” would take me on a thought-provoking journey through the complex realm of artificial intelligence (AI) biases. The show, which was hosted by Sudheer Sharma and covered a range of topics related to AI’s effects on society, made me wonder about the prejudices that these advanced systems may be harboring. Motivated by the insightful discussion, I set out to explore the subtleties of artificial intelligence biases and their practical applications.

From personalized recommendations on streaming platforms to automated decision-making in critical sectors like healthcare and finance, AI algorithms are becoming omnipresent.

As we delve deeper into the world of AI, it’s essential to understand what biases in AI actually is.

Biases in AIrefer to systematic errors or prejudices that are embedded within algorithms, resulting in unfair or discriminatory outcomes. The data used to train the algorithms, the design decisions made throughout the development process, and even the innate biases of the people involved in designing the AI systems can all be sources of these biases.

Understanding the Impact

Biased AI algorithms may have far-reaching and significant effects that have an array of effects on people and communities. Prejudiced algorithms have the potential to worsen already-existing injustices and discrimination, which can result in various consequences like:

Unfair Treatment: People or groups may be treated unfairly by biased algorithms on the basis of racial, gendered, ethnic, or socioeconomic status.

Reinforcement of Stereotypes: AI systems that use skewed data run the risk of perpetuating negative stereotypes, which would further marginalize communities that are already marginalized.

Lack of Accountability: Because biased algorithms can obfuscate the decision-making process, it might be challenging to hold those responsible for discriminating results accountable.

Examples of Biases in AI

Example 1: Soap Dispenser Not Pouring Soap for Black Skin (Racial Bias)

A soap dispenser that worked flawlessly when used by a light-skinned hand failed to pour soap when a dark-skinned hand was placed under it, according to a video that went viral in 2015. This incident exposed the racial bias ingrained in the soap dispenser’s sensor technology, which was probably tested and calibrated mostly on lighter skin tones, making it incapable of identifying darker skin tones.

The soap dispenser that was unable to identify dark skin tones is among the most well-known instances of AI biases. In this case, people with darker skin couldn’t activate the soap dispenser’s sensor, which kept them from getting soap. People with lighter skin tones, on the other hand, did not encounter any such issues, demonstrating an obvious instance of racial prejudice in the AI-powered device’s design.

Example 2: Biased Hiring Algorithms (Gender Bias)

Several studies have shown that hiring procedures made easier by AI technology exhibit gender biases. In one study, for example, researchers at Carnegie Mellon University discovered that a popular AI recruiting tool systematically ranked male applications higher than equally competent female candidates, displaying bias against female candidates. This bias resulted from the gender differences that were common in earlier hiring decisions reflected in the historical data that was utilized to train the algorithm.

For example, algorithms trained on past recruiting data may unintentionally pick up on and reinforce biases in the data, which could lead to unfair outcomes for job candidates based on age, gender, or race.

Example 3: Predictive Policing (Predictive policing bias)

In predictive policing, police resources are distributed based on algorithms that examine past crime data to predict future criminal behavior. These algorithms, nonetheless, have come under fire for maintaining the racial biases present in law enforcement procedures. An AI-powered risk assessment tool used in criminal justice systems, for instance, was shown to be biased against black defendants, falsely classifying them as more risk than white defendants with comparable backgrounds, according to a ProPublica study. People from minority communities were treated disproportionately worse as a result of this biased algorithm.

Algorithms used in predictive policing, which estimate criminal behavior and distribute law enforcement resources appropriately, have come under fire for encouraging racial profiling and excessive police in underprivileged areas. These algorithms frequently use skewed past crime data, which causes certain demographic groups to be disproportionately monitored.

Addressing Bias in AI

It will need a coordinated effort from many stakeholders, including engineers, ethicists, and policymakers, to address biases in AI. Among the methods for reducing bias in AI are:

  • Diverse and Representative Data: Ensuring that training data used to develop AI algorithms is diverse, representative, and free from biases.
  • Transparency and Accountability: Promoting transparency in AI development processes and establishing mechanisms for accountability and oversight.
  • Ethical Considerations: Incorporating ethical considerations into the design, development, and deployment of AI systems to minimize potential harms and promote fairness and equity.

Biases in artificial intelligence provide a serious problem that must be addressed with caution and proactively. We may strive toward developing AI systems that are more egalitarian, inclusive, and representative of our diverse society by increasing awareness, encouraging cooperation, and giving ethical considerations first priority. Let’s make sure that, as we continue to use AI to spur innovation and advancement, we do so in a way that upholds morality and justice for all.

Threat of Deepfake AI Videos with Real-World Case of Rashmika Manadanna

Hello everyone, welcome to DataSagar.com again! In today’s ever-evolving technological landscape, the rapid progress of Artificial Intelligence (AI) and Machine Learning (ML) has bestowed upon us an array of extraordinary capabilities. These innovations have reshaped industries and revolutionized our lives in ways we couldn’t have imagined a few decades ago. However, amid this transformative journey, we encounter a looming shadow — the unsettling realm of Deepfake videos. In this article, we delve deep into the world of Deepfake videos, uncover their malevolent misuse, and explore their profound impact on society with recent real-world case of Indian Actress Rashmika Mandana and Zara Patel. Let’s get started!

Understanding Deepfake Videos

Deepfake videos, at first glance, may seem like a modern trick of movie magic. They involve the artful manipulation of video footage through the application of AI and ML algorithms, effectively replacing one person’s appearance and sometimes even their voice with that of another. The resultant videos can convincingly portray individuals saying or doing things they never did in reality. On the surface, this may appear as an intriguing technological feat, but the implications run far deeper, carrying the potential for deception, misinformation, and the creation of impeccable forgeries.

The Intricate Process Behind Deepfake Videos

To comprehend the enormity of the issue, we must first understand the mechanics of Deepfake video creation. The process is a sophisticated one, comprising several key stages:

  1. Data Collection: The foundation of any Deepfake video is a substantial amount of video and audio footage of both the target person (the individual to be replaced) and the source person (whose likeness is borrowed for the substitution).
  2. Training: Complex deep learning models, such as Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs), analyze and learn patterns within the collected data. These models generate a representation of the target person’s facial features and expressions.
  3. Face Swapping: The Deepfake algorithm then meticulously replaces the target person’s face with that of the source person. This intricate process involves aligning facial features and making frame-by-frame adjustments to craft a seamless and convincing replacement.
  4. Fine-Tuning: To elevate the authenticity of the Deepfake, post-processing techniques come into play. These may include blending the swapped faces seamlessly, adjusting lighting, and mastering the art of manipulating shadows.
  5. Audio Manipulation (Optional): Some Deepfake videos also incorporate voice synthesis or manipulation to ensure the target person’s voice aligns with that of the source person, creating a more persuasive illusion.

The Dark Side: Misuse of Deepfake Technology

While Deepfake technology holds potential for benign applications, its misuse raises significant concerns. Let’s delve into some instances of misappropriation and the reverberations they carry:

  1. Identity Theft: Deepfake videos can be used to impersonate individuals, potentially leading to identity theft, damage to one’s reputation, and fraudulent activities.
  2. Misinformation: Convincing Deepfake videos can effortlessly propagate false narratives, influencing public opinion and eroding trust in media.
  3. Political Manipulation: The political sphere isn’t immune to the machinations of Deepfake technology. These videos can be exploited to influence elections and sow discord.
  4. Financial Fraud: Unscrupulous actors can employ Deepfakes to manipulate financial transactions and deceive unsuspecting victims.
  5. Privacy Invasion: The privacy of individuals is at stake, as anyone’s likeness can be employed without their consent.

Alarming Statistics

The proliferation of Deepfake videos has been nothing short of astounding. According to a report by Deepware Scanner, the number of Deepfake videos online surged by a staggering 330% between 2019 and 2021. This growth is indicative of an urgent need to address this emerging threat.

A Clarion Call for Regulation and Vigilance

The battle against Deepfake misuse is a collective one, requiring the involvement of diverse stakeholders, including tech companies, governments, and individuals. To combat this challenge effectively, the following actions are indispensable:

  1. Legislation: Governments must enact laws that specifically target the creation and distribution of Deepfakes, imposing penalties on those who exploit the technology for malicious purposes.
  2. Detection Tools: Tech companies should allocate resources to develop and implement advanced Deepfake detection tools, effectively identifying and removing fraudulent content.
  3. Media Literacy: Promoting media literacy is essential to empower individuals to distinguish authentic content from Deepfake manipulations.
  4. Ethical AI Use: Developers and organizations working with AI and ML technologies must adhere to ethical guidelines and standards, ensuring responsible and transparent applications.

Real-World Case: Rashmika Mandanna and Zara Patel

The recent case involving Indian actress Rashmika Mandanna and British influencer Zara Patel highlights the stark dangers of Deepfake technology. Rashmika Mandanna fell prey to cybercrime after her deepfake AI video went viral, showcasing her in situations she never participated in. Zara Patel, the original person in the video, has also expressed her distress and concerns about the misuse of her image.

In a statement, Rashmika Mandanna described the incident as “scary,” emphasizing that it is “not only for me but also for each one of us who today is vulnerable to so much harm because of how technology is being misused.” She highlighted the emotional impact, expressing that she couldn’t imagine dealing with such an incident during her school or college days.

The woman from the original video, Zara Patel, responded to the fake video, expressing her deep disturbance and distress. She also voiced her apprehension about the future of women and girls, who must now worry about the increased fear of putting themselves on social media platforms.

The Fake Video (With Rashmika Mandana’s Face) vs The Real One (i.e. of Zara Patel)

The Call for Urgent Action:

This real-world case underscores the urgency of addressing the deepfake menace. The misuse of Deepfake technology can wreak havoc on individuals’ lives, tarnish reputations, and spread misinformation. Indian IT Minister Rajeev Chandrashekhar rightly pointed out that deepfakes represent an even more dangerous and damaging form of misinformation, necessitating swift action from social media platforms under India’s IT rules.

The rise of Deepfake videos is a compelling reminder of the dual nature of AI and ML technology. While they bring us remarkable benefits, they also introduce profound risks when misused. The proliferation of Deepfake videos serves as a stark reminder of the dual nature of AI and ML technology.

Japan’s Own AI Revolution: Building ChatGPT with a Sushi Twist!

Hey there, tech-savvy friends! It’s your pal, DataSagar, and boy, do I have some hot and steaming tech news for you! Japan, the land of sushi, sumo, and, let’s not forget, super cool tech gadgets, is venturing into the wild world of AI chatbots. They’re crafting their own version of ChatGPT, that chatty AI sensation from the folks over at OpenAI. It’s like they’re cooking up their special recipe for tech takoyaki!

Picture this: the Japanese government, along with tech bigwigs like NEC, Fujitsu, and SoftBank, are tossing in hundreds of millions of dollars to whip up AI systems that speak fluent Japanese. Yep, you heard it right, they want their AI to talk like a local, not some lost-in-translation robot.

So, why all the fuss, you ask? Well, it turns out, current AI models, like ChatGPT, are like wizards in English but stumble over their kimono when it comes to Japanese. You see, Japanese isn’t just a different language; it’s a whole different beast. While English has a cozy 26-letter alphabet, Japanese is flexing its muscles with two sets of 48 basic characters and over 2,000 Chinese characters (they call ’em kanji). It’s like the AI equivalent of juggling sushi knives!

Imagine this: when ChatGPT tries to converse in Japanese, it sometimes throws out super rare characters that most folks have never laid eyes on. It’s like trying to read a secret ninja code. Trust me, it’s not easy!

But it's not just about language; it's also about cultural finesse. Think of it this way: if ChatGPT were Japanese, it might pen a job application email that's about as polite as a sumo wrestler in a tea ceremony. It would scream "English translation alert!" They want their AI to blend in seamlessly, like a ninja in the night.

To see just how well these AI chatbots blend in, some crafty researchers invented a ranking system called Rakuda. They basically asked ChatGPT to tackle tricky questions about Japanese culture and evaluated how smoothly it handled them. Surprise, surprise! ChatGPT, aka GPT-4, aced the test, claiming the top spot. Go, GPT-4, go!

But don’t count out the Japanese just yet. They’ve got their secret weapon: the Fugaku supercomputer. This beast is one of the fastest in the world, and they’re using it to train a Japanese LLM (that’s Large Language Model, not some new sushi roll). This homegrown Japanese LLM, slated for release next year, will be open source, which means everyone can get a taste of its coding magic. They’re aiming for a whopping 30 billion parameters – that’s tech speak for its size and complexity.

But wait, there’s more! Japan’s Ministry of Education, Culture, Sports, Science, and Technology is splurging big bucks to create an AI for science stuff. It’s like having a lab assistant that can generate scientific hypotheses by reading research papers. They’re starting with 100 billion parameters – that’s over half the size of GPT-3! It’s a colossal effort that could speed up scientific discoveries, but it’ll cost them a cool ¥30 billion (about US$204 million) and won’t hit the scene until 2031. Science takes time, folks!

And you know what’s really cooking in Japan’s tech kitchen? Companies like NEC and SoftBank are already putting their Japanese LLMs to work. NEC’s generative AI is slicing and dicing report writing and software code, while SoftBank is pouring ¥20 billion into creating its very own LLM. They’re gearing up to serve universities, research institutions, and more. It’s like a tech sushi train, but instead of sushi, you get AI smarts!

In the end, Japan’s quest to create a top-notch, culturally savvy AI chatbot isn’t just about tech.

Welcome to the fascinating world of Non-Fungible Tokens (NFTs), brought to you by NuvaNFT.io, your go-to platform for discovering, collecting, minting, selling, and buying NFTs. Whether you’re a seasoned cryptocurrency enthusiast or just dipping your toes into the world of blockchain technology, NuvaNFT.io is here to guide you through the essential aspects of NFTs, including what they are, what gives them value, and how you can get started creating and trading NFTs on our platform.

What Are NFTs, and Why NuvaNFT.io?

A Non-Fungible Token, or NFT, is a unique digital token that exists on a blockchain, such as Ethereum.

Can I view message without sender knowing it? – Mastering Facebook Messenger with its history

Hi everyone! Welcome to yet another blog post on the simple everyday tool of common interest that many of you might have thought of. i.e., Facebook Messenger, and the secrets behind using it as a pro.

Image: History of Facebook Messanger by DataSagar

In the ever-evolving landscape of communication, Facebook Messenger App has emerged as a prominent platform for instant messaging. Launched in August 2011, it has transformed the way we interact and stay connected with our friends and family. However, one question that frequently arises is whether it’s possible to read messages on Facebook Messenger without the sender knowing. In this blog post, I will explore the intricacies of Facebook Messenger, its messaging icons, and uncover whether reading messages incognito is indeed possible. So, why do late. Let’s begin!

A Brief Overview of Facebook Messenger

Facebook Messenger, an extension of the Facebook ecosystem, offers users the ability to engage in real-time conversations with friends and contacts. Initially introduced as Facebook Chat in 2008, it underwent a significant revamp in 2011 and rebranded as Facebook Messenger. Notably, while the service was initially tied to Facebook accounts, it now facilitates communication within multiple platforms, including Facebook, Instagram, Portal, and Oculus VR.

The Messaging Icons: Decoding Message Status

To understand the possibility of reading messages discreetly, it’s essential to comprehend the messaging icons and their meanings within Facebook Messenger. These icons play a crucial role in conveying the status of messages. Here’s a quick rundown:

Image: Meaning of Messenger icons by DataSagar
  • Blue Circle : Your message is being sent.
  • Blue Circle with a Check: Your message has been sent.
  • Filled-in Blue Circle with a Check: Your message has been delivered.
  • Small Profile Picture: Indicates that the recipient has seen your message.

Why Do Messages Say “Sent” Instead of “Delivered”?

The term “SENT” signifies that your message has been submitted to the cellular network for immediate delivery. On the other hand, “DELIVERED” means the message has reached the recipient’s device but hasn’t been read yet.

Interpreting Message Delivery and Seen Status

When a message appears with a blue circle and a check, it means your message has been sent. A filled-in blue circle indicates successful message delivery. Furthermore, the appearance of a small version of the recipient’s profile picture signals that the message has been seen.

Messages that remain in the “Sent” state without advancing to “Delivered” might indicate that the recipient hasn’t logged into Facebook or has blocked you on Messenger.

Reading Messages Stealthily: Is It Possible?

Now, let’s delve into the methods people seek to employ to read messages incognito.

  1. Enabling Airplane Mode: One strategy to read messages without notifying the sender is by enabling Airplane Mode. When activated, Airplane Mode cuts off the Messenger app’s access to the internet. You can then open the Messenger app and read messages without triggering read receipts. Upon reconnection, your read status won’t be displayed to the sender.
  2. App Notification: If you’ve enabled push notifications for Messenger, you can view incoming messages on your notification bar without opening the app. This method allows you to gauge message content and the sender’s identity without triggering read receipts.
  3. Third-Party Plug-Ins: For desktop users, third-party extensions like “Unseen” for Chrome and “Message Seen Disable” for Firefox can be valuable tools. These extensions prevent read receipts from being sent, enabling you to read messages undetected.

While Facebook Messenger offers an array of icons to convey message statuses, reading messages incognito without the sender knowing can be a delicate matter. The aforementioned methods, such as Airplane Mode and third-party extensions, provide users with the ability to discreetly peruse messages. However, it’s important to approach this with respect for others’ expectations of communication transparency. Ultimately, while technology presents us with innovative ways to manage our online interactions, maintaining open and honest communication remains paramount.

The Uncertain Future of OpenAI: A Deep Dive into Challenges and Potential Bankruptcy

Greetings, dear readers, and welcome back to DataSagar, your compass in the ever-evolving realm of technology. Today, I’ll be taking you on an insightful journey to exploring the unfolding narrative surrounding one of the AI world’s trailblazers – OpenAI. As the architects of groundbreaking technologies that have ignited conversations around AI for both tech-savvy enthusiasts and everyday individuals, OpenAI has stood as a harbinger of innovation. However, as the winds of change blow strong, recent developments have cast a shadow of uncertainty over OpenAI’s future. In this article, we delve deep into the multifaceted challenges that OpenAI faces, the intricate web of circumstances that have brought them to this crossroads, and the looming question: Could OpenAI’s path eventually lead to the unexpected territory of bankruptcy? Join us as we navigate through trademark disputes, shifting user preferences, intense competition, and more, unraveling the tale of OpenAI’s precarious position in the AI landscape.

OpenAI has long been a leader in the field of artificial intelligence, spreading awareness of the technology through the use of ChatGPT, a well-known chatbot. But according to recent reports, a worrying pattern could put OpenAI in danger of going bankrupt. This article explores the different aspects of OpenAI’s possible financial difficulties, including trademark issues, changing user preferences, and fierce competition.

Trademark Troubles and User Exodus

OpenAI’s journey took an unexpected turn when it sought to trademark the term ‘GPT’, which is integral to their generative AI technology. This move was viewed by many as the start of OpenAI’s downfall, fostering concerns that people would eventually lose interest in their technology. Although the trademark application was unsuccessful, a notable shift in user behavior has become evident.

At first, the decline in usage of the ChatGPT website was attributed to the summer break for students or the introduction of the ChatGPT API, allowing users to create their customized bots. However, this initial decline was a harbinger of a more significant problem.

API Cannibalization and Declining User Base

The decline in user engagement became more pronounced as time went on. Analytics provided by SimilarWeb showed a 12% decrease in users from June to July, dropping from 1.7 billion to 1.5 billion users. However, this statistic does not include API usage, which has become the primary revenue source for OpenAI.

A pivotal factor in this decline appears to be the cannibalization of the original ChatGPT usage by the API. Many companies encouraged their employees to integrate the ChatGPT API into their workflows rather than using the standalone service. This shift not only affected user numbers but also highlighted OpenAI’s challenge in convincing users to opt for their proprietary solution over other open-source and free alternatives.

Competition and Shifting Landscape

OpenAI’s user decline is not solely a result of API usage; open-source large language models (LLMs) have played a substantial role. The example of Meta’s LLaMA 2, developed in partnership with Microsoft, is significant. This LLM not only allows commercial use but also offers adaptability and flexibility, raising questions about why someone would choose OpenAI’s proprietary version over such alternatives.

Furthermore, OpenAI’s transformation from a non-profit to a profit-oriented venture, coupled with Sam Altman’s lack of equity ownership, raises concerns about their focus on profitability. Despite this shift, OpenAI has yet to achieve profitability, accruing losses of $540 million since the inception of ChatGPT.

Financial Challenges and Microsoft’s Lifeline

The financial outlook for OpenAI seems to be murky as well. Microsoft’s $10 billion investment has sustained the company for now, but OpenAI’s projections of reaching $200 million in annual revenue in 2023 and aspiring for $1 billion in 2024 seem ambitious, given their mounting losses.

Transitioning to a paid model generated revenue, but the path to profitability remains uncertain. Potential income sources include API sales and offerings like GPT-4-based chatbots or DALL-E2, but specifics remain unclear. The cost of operating ChatGPT, around $700,000 daily, presents a significant financial challenge. These expenses are currently supported by Microsoft and recent investors, but sustainability remains questionable.

Competitors and GPU Shortages

Historically, industry giants like Google and Meta were OpenAI’s primary rivals. However, the landscape has shifted with the emergence of Musk’s xAI, introducing heightened competition. Musk’s vision for a “TruthGPT,” devoid of political bias, has garnered attention and resources, including 10,000 NVIDIA GPUs, signifying his commitment to challenging OpenAI’s dominance.

Complicating matters, the ongoing GPU shortage hampers OpenAI’s ability to improve and train new models. Despite filing for a trademark on ‘GPT-5,’ this pursuit has led to diminished output quality for ChatGPT.

The Dire Path Ahead

Considering these complex circumstances, OpenAI’s future is fraught with challenges. Additional funding is imperative to acquire GPUs and resume model training. The absence of prompt funding might necessitate filing for bankruptcy by the end of 2024.

As challenges mount, financial losses grow, user numbers dwindle, legal disputes accumulate, and output quality falters, OpenAI faces an arduous path forward. The journey that began with promise and innovation is now mired in uncertainty, showcasing the unpredictability of the AI landscape.

OpenAI’s trajectory from trailblazer to potential bankruptcy serves as a cautionary tale, highlighting the intricate interplay of factors in the AI industry. Whether OpenAI can weather the storm and regain its footing remains a question that only time will answer.

What is Non-Fungible Token or NFT? A simple definition with an example

If you’ve been following the latest trends in the digital world, you might have come across the term “NFT.” But what exactly does it mean? In simple terms, an NFT, which stands for Non-Fungible Token, is a unique digital item that can be bought, sold, and owned. It represents something one-of-a-kind and cannot be exchanged on a one-to-one basis like traditional currencies.

To better understand NFTs, let's compare them to something more familiar: money. Money is fungible, meaning that each unit is equal to any other unit of the same value. For instance, if you exchange an NPR 10 bill with another NPR 10 bill, you still have the same value. However, NFTs are non-fungible because each one is distinct and cannot be directly swapped with another NFT without considering its individual characteristics.

An excellent way to visualize NFTs is by thinking of them as digital collectibles. Just like you might collect physical items like baseball cards or stamps, NFTs allow you to collect and own unique digital assets. These assets can include digital art, music, videos, virtual real estate, virtual pets, and even moments from sports or entertainment events.

Let’s take a look at a simple example to illustrate how NFTs work. Imagine you’re a digital artist named Laxmi, and you create a stunning piece of digital art. Instead of selling it as a physical painting, you decide to turn it into an NFT. By doing so, you can verify and prove that you are the original creator and owner of that specific artwork using technologies like blockchain.

Once the NFT is created, you can list it for sale on an NFT marketplace. This is where potential buyers can discover your artwork and make a purchase. When someone buys your NFT, they are essentially purchasing a digital certificate of ownership. They may not have the physical artwork itself, but they own the original and unique digital assets.

As an artist, you can also include additional benefits for the buyer. For example, you might specify that the buyer gets exclusive access to behind-the-scenes content related to the artwork, or you can grant them special privileges in future releases. Or, maybe the access pass or any other benefits related to the game or product/services that artwork is being used, same as in the Mushroom Kingdom NFT collection by NuvaNFT where they’re developing a game using the NFT characters from collection like Nomins, Grutzis, Hidois, and Kaioji etc. that creators are selling now. With the game that the Nuva Group set to develop with story behind characters they’re selling now, collectors can get access pass or other benefits of Nuva ecosystem later on. This type of associations adds value and enhances the overall ownership experience of users as well.

FYI, In the enchanting land of the Mushroom Kingdom by NuvaNFT, a diverse array of beings thrived, each playing a unique role in shaping the fate of their realm. Among these were the peaceful and hardworking Nomins, the malevolent Grutzis seeking power, the noble and brave Hidois, and the resolute and compassionate ruler, King Kaioji.

Now, let’s consider the buyer of your NFT. They can showcase their ownership of the artwork publicly or keep it in their digital collection. They may also choose to sell the NFT in the future, potentially at a higher price, if the artwork becomes more valuable or sought after. The blockchain technology behind NFTs ensures that ownership and transaction history are transparent and cannot be tampered with, providing trust and security for all parties involved.

It’s important to note that NFTs have gained significant attention and popularity recently, with artists, celebrities, and creators embracing this new digital medium. However, like any new technology, there are challenges and considerations. For instance, the environmental impact of blockchain technology and the potential for copyright infringement are valid concerns that need to be addressed as the space evolves.

NFTs represent a unique and exciting way to own and trade digital assets. They provide creators with new opportunities to monetize their work and engage with their audience. Whether you’re an artist, a collector, or simply curious about the digital world, NFTs are reshaping the way we think about ownership in the digital age.

So, keep an eye out for NFTs, explore the vibrant NFT marketplaces like NuvaNFT and Opensea, and embrace the possibilities of owning and experiencing digital assets like never before.

Nepal’s New E-commerce Bill: An In-Depth Analysis of Its Impact on the Industry

Namaste, dear readers! I am DataSagar, a passionate blogger and an enthusiastic advocate of all things ICT. Today, I want to share my thoughts on Nepal’s recent e-commerce bill that has been making waves in the online community. As someone deeply involved in the world of e-commerce, I cannot help but feel both excited, concerned and worried about the potential impact of this new legislation in e-commerce arena of Nepal.

In recent times, the rapid growth of e-commerce has transformed the way people conduct business and trade across the globe. Realizing the significance of this sector, the Nepal government has taken steps to regulate e-commerce within the country. However, the new e-commerce bill of Nepal, though well-intentioned, has raised concerns among various stakeholders. This article delves into the provisions of the bill and explores its potential impact on the e-commerce ecosystem in Nepal.

Let’s dive into the details and explore what this e-commerce bill means for individuals like me who have embraced the digital realm to connect, trade, and thrive.

Excitement About Regulation

At first glance, the government’s efforts to regulate e-commerce in Nepal appear to be a step in the right direction. As a technology blogger and lecturer of e-commerce since a decade, I understand the importance of creating a safe and secure online environment for consumers and businesses alike. With the rapid growth of e-commerce, it becomes crucial to ensure fair practices, protect consumer rights, and instill confidence in the digital marketplace.

Key Points in The Bill and Their Impacts

The bill requires e-commerce platforms to provide comprehensive details about products or services, including prices, taxes, transportation costs, delivery time, and customer reviews etc. While this ensures transparency and consumer protection, it is sure to increase the burden on e-commerce companies to manage and maintain this information accurately.

To be specific, the bill mandates a predefined set of fields (more than 10 to be exact) for defining each product. While clarity and product categorization are essential, making such requirements mandatory for all products can be impractical, especially for businesses with huge, vast and diverse inventories. 

To safeguard consumer rights, the bill grants buyers the right to return products that do not meet their requirements and receive unconditional refunds.

This provision is a positive step towards ensuring customer satisfaction and trust in the e-commerce sector. 

The bill also is allowing individuals, firms, and organizations in Nepal to purchase products or services from foreign e-commerce platforms and export to international buyers. To protect consumer data, the bill mandates e-commerce businesses to maintain the confidentiality of personal details and restricts the disclosure or unauthorized utilization of such information.

However, it imposes the condition of fulfilling advance payment requirements as per existing federal laws.

I must say, while the e-commerce bill is an essential step towards regulating our growing digital marketplace, some provisions have raised eyebrows, and the requirement for prior payment for exporting products/services is one of them. It seems like the government might need a deeper understanding of the nuances of cross-border trade and consider more flexible approaches to foster international business collaborations. Not every business can afford to demand advance payment for exports.

This rigid provision might limit opportunities for smaller businesses to expand globally and could hinder the growth potential of our local entrepreneurs. Let's hope for further discussions and amendments to ensure the best possible environment for our e-commerce community.

The bill placed greater responsibility on e-commerce platforms when acting as intermediaries. This means that in cases of faulty products or services, e-commerce platforms are obligated to facilitate warranties, exchanges, and refunds.

This shift of liability from the seller to the platform may lead to increased compliance costs and potential hesitancy among e-commerce companies to offer a diverse range of products.

Another aspect to note out is that the bill requires e-commerce businesses to submit an online application for listing on the government-established “e-commerce portal.” Existing e-commerce companies must apply for listing within three months from the commencement date of the Act.

Failure to get listed within the specified period may lead to penalties or restrictions on conducting transactions and may incur fines as well. Seems quite irrelevant and strange provisions as compared to rest of the countries around the world with well-developed IT and Network infrastructures which are doing way better in e-commerce.

Additionally, the stipulation for a software-based ticket generation system is also emphasized by the bill, which seems irrelevant and troublesome for SMEs thinking of entering the e-commerce arena with limited resources.

This may hinder aspirant entrepreneurs and youths trying to get into the ecommerce market.

The Bill’s Impact on SMEs

However, while the intentions behind the e-commerce bill seem noble, I must confess that I am worried about its potential impact on Small and Medium Enterprises and startups trying to uplift Nepal’s startup ecosystem. The requirement for written contracts with intermediaries and the added responsibility placed on e-commerce platforms could create hurdles for aspiring entrepreneurs. With lots of paperwork, lack of automation and cumbersome processes, this might get more complicated in place of solving pain points of ecommerce entrepreneurs.

Imagine you’re a young entrepreneur with a brilliant e-commerce idea, and you dream of bringing it to life. The new bill might make you think twice about taking that leap of faith. The complex registration process and the burden of fulfilling all the mandated fields for product definitions might discourage newcomers from entering the e-commerce landscape.

Balancing Consumer Protection and Business Growth

Don’t get me wrong; consumer protection is paramount. The provisions for comprehensive product and service information, buyer’s right to return, and data privacy are essential for building trust with customers. However, we must find a balance that encourages entrepreneurship and innovation without compromising on consumer rights.

Witnessing hurdles of ecommerce closely since more than a decade, I firmly believe that the success of any e-commerce ecosystem lies in its ability to foster growth, inspire creativity, and empower small businesses to thrive.

Challenges Ahead

The new bill also introduces the concept of an “e-commerce number,” and obtaining it requires registration at multiple places. I wonder how this process could become a lengthy and tiresome affair, possibly acting as a deterrent for those who wish to join the e-commerce revolution.

Moreover, the mandate for e-commerce platforms to have a software-based ticket handling system may be challenging for startups with limited resources. This requirement could potentially slow down their growth and hinder their ability to provide top-notch customer service.

Opportunities for Growth

While I appreciate the efforts to regulate the e-commerce industry, I urge the government and policymakers to consider the needs of small businesses and startups and do necessary home work with market leaders like Hamrobazar, Daraz, SastoDeal, and so on. Simplifying registration procedures, offering support for compliance, and providing incentives for growth can go a long way in creating a thriving e-commerce ecosystem in Nepal.

Lastly, Nepal’s e-commerce bill signifies a significant step towards a more organized and secure digital marketplace. However, it is vital to strike a balance between consumer protection and encouraging the growth of small businesses. While the intentions are commendable, there are valid concerns regarding the potential hindrance it may pose to new startups and the operational complexities it may add to existing e-commerce companies.

As the bill goes through the legislative process, it is essential for policymakers to strike a balance between protecting consumer interests, encouraging e-commerce growth, and promoting entrepreneurship. Flexibility and provisions that support startups and small businesses could be crucial in fostering a thriving e-commerce ecosystem in Nepal. Regular consultations with industry stakeholders and amendments based on feedback will be vital to ensuring a successful implementation of the e-commerce bill that benefits all parties involved. I look forward to seeing amendments and consultations with industry stakeholders that address these concerns.

Microsoft developing its own AI chip Athena to reduce Machine Learning costs — DataSagar

Welcome back to yet another blog post on DataSagar! This post is a continuation of my blog series on Artificial Intelligence. As a technology educator and e-business consultant, I aim to provide insightful articles and helpful tips to keep you up-to-date with the latest developments in the world of tech. In this article, we’ll be discussing Microsoft’s latest project: developing its own artificial intelligence (AI) chip code named “Athena.”

Microsoft is reportedly working on their new chip project called Athena which is supposed to be an AI processor intended to power the technology powering AI chatbots like ChatGPT, which will be used to train the substantial language models required by generative AI. Massive volumes of data are provided by these chatbots, which can also spot trends and imitate human speech. Microsoft expects Athena to outperform the chips it presently purchases from other vendors, saving time and money on its pricey AI research and development.

The market for these chips is presently dominated by Nvidia, but Microsoft aims to change that with Athena. Developed in 2019, the chip is now being tested by a small team of Microsoft and OpenAI staff members. Athena is reportedly being developed by more than 300 employees, and Microsoft anticipates that it will be offered to Azure users by the end of the year.

According to Dylan Patel, principal analyst at SemiAnalysis, “Microsoft wants to use large language models in all of their applications, including Bing, Microsoft 365, and GitHub.” The corporation might save tens of billions of dollars as a result.

As a result of ChatGPT’s success, Microsoft is quickening the rollout of Athena. In an effort to compete with Google and capitalize on its cooperation with OpenAI, Microsoft earlier this year released Bing AI, its own AI-powered search engine.

Microsoft’s upcoming Surface PCs will also come with an NPU (neural processing unit) to speed up on-device artificial intelligence and machine learning (ML), in addition to Athena. Microsoft now employs chipsets with NPUs from AMD, Intel, and Qualcomm, all of which are currently adding them to their microprocessors.

It is obvious that Microsoft is making significant investments in AI, and with the creation of Athena, it aspires to dominate the AI chip industry. Although Nvidia presently rules the market, it is still unclear how Microsoft’s chip will function and whether it will be able to challenge the top chip maker. Whatever the case, AI and technology as a whole are in an exciting phase right now, and we can’t wait to see what the future brings.

The idea of developing AI chips internally is not new; companies like Amazon, Google, and Facebook already produce AI chips. It’s an increasing trend as tech behemoths grasp AI’s potential and how it can completely transform the market. These businesses can save costs on their time- and money-consuming AI endeavors with the development of AI chips.

Additionally, the epidemic has increased technology use and raised demand for AI-powered products and services. In light of this, Microsoft’s investment in AI chips may prove to be a big step forward for the business, allowing it to increase its product offerings and competence in the AI sector.

You should know that ChatGPT and other language models need high-capacity AI devices to do their computations effectively. The size and complexity of the model determine how much processing power is needed.

Modern language generation models like ChatGPT, which are built on the GPT-3 architecture and trained using enormous amounts of data, demand a lot of computing power. Depending on the situation, ChatGPT may consume more or less processing power, although it normally needs strong GPU clusters or specialist AI chips.

For instance, a supercomputer with approximately 3,000 graphics processing units (GPUs) and 192 server-class CPUs was used to train the greatest version of GPT-3, which has 175 billion parameters. Although ChatGPT is a more compact model than GPT-3, it still needs a lot of computing power to function properly.

And yes, whatever it be, Microsoft’s creation of its own AI chip is a positive step forward for the field of artificial intelligence. Microsoft expects that Athena will outperform the chips it presently purchases from other vendors, saving time and resources on its pricey AI research and development. AI is undoubtedly the technology of the future, and by making this investment, Microsoft is establishing itself as a significant player in the AI chip industry. It will be interesting to see how Athena does on the market and how it counters Nvidia’s hegemony.

Can AI Build Another AI System More Advanced Than Itself? Exploring the Possibility and Implications

In recent years, the topic of artificial intelligence (AI), which is quickly developing, has attracted a lot of attention. Being a technopreneur and computer science educator, I’ve been paying great attention to this subject as the AI revolution started to hit the world more strongly than ever. I’ll try to cover whether AI can create a system that is more potent than itself in this blog post.

Firstly, Let’s define AI before putting forward an opinion. The term Artificial Intelligence (AI) can be understood simply as computer programs that can carry out tasks that ordinarily require human intelligence. Content Generation and Translation of languages, speech recognition, decision-making, and visual perception are a few of them. A subset of Artificial Intelligence(AI) called machine learning enables systems to learn from data and enhance their performance over time.

So, the main question is, “Can AI thereby develop more potent AI systems?”. I think Yes, that is feasible. AI systems can be trained to create increasingly complex AI systems as they continue to learn and collect more data. Also, Machine learning that is automated is known as AutoML. You might already have heard about this term. A number of IT firms are already employing AutoML to build intricate AI models that can be leveraged to build even more sophisticated systems. This sets up a cycle of exponential growth that might someday result in the development of incredibly potent AI.

Secondly, It’s important to remember, though, that the emergence of more sophisticated AI systems does not portend the extinction of humanity. Despite the fact that AI is capable of performing many activities that people do, it cannot replace human experience and emotions at least in near future. In many businesses, empathy, inventiveness, and interpersonal contact are essential skills that machines cannot take the place of.

In addition, massive volumes of data are needed for AI systems to learn and advance. Humans must contribute this data, and restrictions must be put in place to guarantee that AI systems are operating properly. In order to guarantee that AI is used ethically and responsibly, human oversight is essential.

There is a chance that AI could create more sophisticated AI systems in the future. However, it’s imperative to go slowly and make sure that AI is used in an ethical and responsible manner. Humans will still be necessary for giving data and supervising AI systems as they develop. It’s more likely that AI will be utilized to boost productivity and efficiency across a range of industries than it will be to completely replace people.

At last, What do you think about AI and the possibilities for developing more sophisticated AI systems? Comment below with your thoughts, and don’t forget to share this article with anyone you think would be interested in the subject. Have a good day!

It’s almost too funny to say that Twitter has become X, but here we are! haha!

Elon Musk’s intentions for the social media platform have been the subject of rumors following the recent merging of Twitter and the newly created X Corp. Twitter “no longer exists” as a result of the merger with X Corp, claims a document filed in a California court for a case brought by conservative activist Laura Loomer against the company and its former CEO Jack Dorsey. The document is getting attention on social media platforms since yesterday.

Although the effects of this move are not yet evident, it is important to remember that Twitter has experienced considerable adjustments since Musk purchased the business for $44 billion last year. The billionaire has previously made suggestions that Twitter might become a “everything app” under the X name, perhaps competing with Chinese social media giant WeChat.

Despite the absence of official statements, there are rumors that this merger may mark the beginning of the development of the X app. It is also conceivable that this action may lead to the creation of a larger parent organization called X that would govern all of Musk’s ventures, including Tesla and SpaceX.

It’s interesting to note that Twitter is now headquartered in Nevada rather than Delaware under X Corp. However, the new X Corp will inherit all of the debts and lawsuits that Twitter and Musk faced before to the merger.

The fact that Elon Musk now owns the “X.com” domain, which he previously used for a payment service that was incorporated into PayPal, fuels even more rumors about what he has in store for the X name.

On Tuesday, Musk tweeted about the change with just the letter “X.” as well.

It is crucial to remember that Twitter is still a fully functional social media network, but debate still surrounds the types of content and individuals it allows and disallows. Many members of the IT community are turning to other platforms for safety as a result as well.

Concerns regarding the future of the social media platform have been sparked by the merging of Twitter and X Corp. Even while it’s yet unclear whether this merger will result in the development of the X app or whether it’s simply a part of a bigger reorganization of Musk’s properties, it’s obvious that it’s a big deal for Twitter and its future.

Threats and attacks in Network Environment

A critical component of the contemporary digital environment is network security. The prevalence of internet-connected gadgets and cloud computing has increased the frequency of network security risks and attacks. The infrastructure, data, and reputation of a business could all suffer severe harm as a result of these risks and attacks. We will talk about many dangers and attacks in a networked environment one-by-one in this article.

Malware, often known as malicious software, is a category of a program intended to harm, interfere with, or allow unauthorized access to a computer system. Malware is one sort of attack. Malicious software, including viruses, trojan horses, worms, and spyware, can spread throughout a network and infect numerous computers, seriously jeopardizing the security of the entire system. This means Malware can take many different shapes, including viruses, trojan horses, worms, and spyware. These dangerous applications have the potential to proliferate throughout the network and infect several systems, seriously jeopardizing network security.

Another danger is phishing, which employs deceptive strategies to coerce people into disclosing personal data like passwords and usernames. These attacks may take the shape of emails, pop-up windows, or phony websites made to look like the real thing. In another word, Phishing is a type of social engineering attack that uses dubious methods to get people to divulge private information like usernames and passwords. These assaults frequently take the shape of emails, pop-up windows, or phony websites that imitate trustworthy ones. Once the attacker obtains the data, they can access the network and jeopardize the security of the system.

Network security can also be compromised by denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks. These attacks are intended to flood a network or a particular system with traffic, rendering it inaccessible to authorized users. DoS and DDoS assaults have the potential to seriously disrupt enterprises and result in large financial losses.

Attacks known as “man-in-the-middle” (MitM) occur when an attacker eavesdrops on a conversation between two parties in order to access and alter the data being transferred. Attackers can insert harmful code into databases through SQL injection attacks, which target poorly protected databases.

Attacks using passwords are another danger. Automated password attacks are possible and can use a variety of methods, including brute force, dictionary, and rainbow table attacks. An attacker can access the network and compromise its security once they have the password.

Last but not least, insider threats can be deliberate or accidental. When a worker or contractor with access to the network harmed the network purposefully or accidentally, it is referred to insider threat. Data theft, sabotage, and illegal network access are some examples of insider risks.

Safeguarding the security of electronic commerce networks requires an understanding of the various threats and assaults. Networks can be protected from potential threats and attacks by implementing the right security measures, such as firewalls, intrusion detection systems, and anti-malware software.

Is Real State B2B or B2C? – eCommerce

Hi everyone, welcome to datasagar. Many of you might have been confused about what category of E-commerce online real estate companies belong to. Here, I’ll try to decipher it for you.

Depending on the type of real estate transaction and the parties involved, the real estate sector can be classified as either a B2B (business-to-business) or a B2C (business-to-consumer) enterprise.

A real estate agent or broker deals directly with a consumer to purchase, sell, or rent a property in a B2C transaction. The real estate agent offers services like finding properties, listing them, scheduling showings, negotiating offers, and finalizing the sale or lease. This transaction is a B2C relationship because it involves a real estate agent or broker and a single consumer.

Real estate services are offered to other businesses or organizations in a B2B transaction as opposed to to private individuals. For instance, a commercial tenant and a real estate developer might collaborate to lease office space for the tenant’s enterprise. As the transaction in this instance is between the commercial tenant and the real estate developer, it is a B2B relationship.

When a company employs a real estate agent to represent them in the sale or lease of commercial real estate that they own, that is another instance of B2B real estate. Instead of serving a single consumer, the real estate salesperson would be serving the company.

Means, based on the parties involved in the transaction, the real estate business can be classified as either B2B or B2C. Real estate is a flexible and dynamic profession since real estate agents and brokers can offer services to both individual customers and other businesses and organizations.

E-tailing – Online Retailing

Hi everyone, welcome to DataSagar. I’m here with another definition to make your e-commerce understanding even better. And, the term for today is “E-tailing”.

Electronic retailing, sometimes known as “e-tailing,” is the process of selling products and services online. E-tailing is the technique of displaying things, taking payments, and delivering orders all online. Retailers who only do business online are known as e-tailers.

A website or online store where customers may explore products and make purchases using a computer or mobile device is typically involved in e-tailing. By utilizing email marketing or social media platforms, online merchants can promote their goods and connect with potential customers.

E-tailers like Amazon, eBay, and Etsy are a few instances. As more and more individuals shop online for convenience and a greater selection of goods, e-tailing has grown in popularity in recent years.

By fostering entrepreneurship, generating employment opportunities, and assisting the expansion of small and medium-sized businesses, e-tailers around the world are significantly contributing to the country’s economic progress (SMEs). Here are some ways online retailers are boosting the country’s economy:

Increasing employment opportunities: In order to run their businesses, e-tailers need a variety of highly qualified specialists, including web developers, graphic designers, content writers, customer service agents, and logistical staff. E-tailers help the economy expand by providing employment possibilities for people with various skill sets.

The Impact of Automation on the Job Market: Insights from Amazon Go and Amazon Fresh

Hi everyone, welcome to DataSagar. There’s no doubt that you’ve heard about the dispelling myths about the impact of disruptive technology and innovation like e-commerce and AI on the job market, specifically Job Loss. In this article, we’ll try to highlight the positive impact of Amazon Go and Amazon Fresh on the new genres of employment opportunities.

To begin with, the advent of new technologies and automation has sparked a wave of fear among the general public, with many people worrying that they will eventually lead to widespread job losses. While it is true that some jobs will inevitably become obsolete, it is also important to recognize that these new technologies have the potential to create new jobs and stimulate economic growth as well. This appears to be particularly true for Amazon, which has pioneered retail innovation and has made significant investments in cutting-edge technology that are altering how we purchase.

One of the most exciting developments from Amazon is the creation of its unmanned stores, Amazon Go and Amazon Fresh.

Some businesses fully automate the entire purchasing experience, from entry to payment, using modern technologies. Using an app and a turnstile, customers can enter the store and make purchases without a cashier. Because the system can track what users take and return, customers are only paid for what they really purchase.

Despite initial concerns that these retailers would result in job losses, they are instead producing new jobs. For instance, in order to reduce labor costs and boost productivity, Amazon has made large investments in automation and robots for its warehouses. Amazon currently employs over a million people, although this figure has increased quickly due to the company’s rapid growth. Additionally, according to a Morgan Stanley report, cities that are home to Amazon fulfillment centers have seen job growth that is higher than the national average.

The same can be said about Amazon Fresh, which plans to eventually have 1,000 stores and is aggressively expanding its grocery store model across the United States. This new technology will likely result in a reduction in the demand for cashiers, but it will also open up new career opportunities in areas like technology development and maintenance as well as customer service and support.

Farming accounted for 30% of American occupations 100 years ago, but today that percentage is less than 1%. Despite this huge transformation, tens of millions of new jobs have been created across many industries, advancing our society and economy. The same will undoubtedly apply to Amazon and other companies that employ technology to develop and enhance their business processes.

It is important to keep in mind that while it is fair to worry about new technologies and how they can affect employment, they also have the potential to increase employment and the economy. Just as our culture and economy have done in the past, we will be able to adapt to new technologies and automation and thrive.

  10. Target: Customers can perceive things in their homes with Target’s augmented reality app, creating a virtual shopping experience that enables them to make better purchasing selections.

Technology and innovation at this level will undoubtedly put great pressure on businesses to gain competitive advantages. In the long run, we can anticipate that augmented reality (AR) will significantly change how e-commerce will function. As technology continues to advance and the popularity of AR grows, it is likely that more and more businesses will adopt this technology to provide customers with a more immersive and interactive shopping experience. Customers will no longer need to make physical shopping trips and will find online buying to be more convenient because AR will let them to try on clothing, test out furnishings, and even see how things look in their own houses. Additionally, AR will give companies new ways to interact with clients, resulting in a more individualized buying experience that may boost client happiness and brand loyalty. In general, it is anticipated that AR will have a significant impact on how consumers engage with products and businesses in the future and how e-commerce develops.

The Power of Meritocracy, Pragmatism, and Honesty (MPH) – Singapore’s Secret

Welcome to DataSagar.com, where we delve into captivating stories that illuminate the transformative power of data and explore the secrets behind successful nations. Today, we embark on a fascinating journey into the realm of national development, as we uncover the remarkable story of Singapore’s MPH Formula – Meritocracy, Pragmatism, and Honesty. Join me, Hem Sagar Pokhrel, as we unlock the insights behind this powerful formula and discover how it can inspire and shape the future of our very own Nepal. Get ready to be inspired, informed, and motivated as we unravel the essence of this incredible formula and its potential to ignite a new era of progress and prosperity. So, grab a cup of tea, sit back, and let’s dive into this captivating exploration of meritocracy, pragmatism, and honesty, and its relevance for our beloved nation, Nepal.

What sets Singapore apart from other nations is its remarkable journey toward success amidst complex challenges and competing interests. The MPH Formula, which stands for Meritocracy, Pragmatism, and Honesty, is the backbone of this journey, enabling Singapore to successfully transform from a small and resource-poor island to a flourishing global hub. This blog post will delve into the significance of the MPH Formula and how its three pillars have shaped Singapore’s exceptional path toward success.

Meritocracy: A Fair System that Rewards Talent and Effort

Singapore’s triumphant model is rooted in meritocracy or the belief that one’s abilities and accomplishments determine their future, not their birth or social status. Unlike many other societies, this ideology provides equal chances for success to all, regardless of their background. By encouraging competition and excellence, Singapore’s system inspires individuals to reach their full potential, with the promise of recognition and reward for their hard work. This unparalleled approach has allowed the country to fully utilize its human capital and drive progress, tapping into the remarkable abilities of its people.

Pragmatism: Adaptability and Flexibility in the Face of Change

The pragmatic approach to decision-making and problem-solving that has always been a high focus is what makes Singapore such a success story among other countries’ development models. The nation’s authorities stress the need of making sensible decisions that will benefit the majority of its people. The government’s capacity to quickly adjust to conditions altering due to economic upheavals, technical developments, or shifting global dynamics is an example of this pragmatic approach. In a world that is constantly changing, Singapore’s ability to adapt and seize chances has been crucial to its progress and allowed it to stay ahead of the curve.

Honesty: A Foundation of Trust and Integrity

Another important part of the MPH formula is that Singaporean society places a high value on honesty and integrity. Honesty is recognized as a crucial characteristic that supports the advancement of the country by both the government and its population. Because of its dedication to openness and accountability, Singapore has developed a culture of trust where people and institutions can rely on one another. This culture of integrity has helped to create a setting that is favorable to investment, collaboration across borders, and innovation. Additionally, it has helped Singapore maintain its standing as one of the world’s least corrupt nations. Singapore’s growth and development have been aided by the international business, talent, and investment it has attracted by keeping the highest standards of ethics.

Meritocracy, Pragmatism, and Honesty, or the MPH Formula, are the cornerstones of Singapore’s success story. Singapore guarantees that skill and hard work are properly acknowledged and rewarded by embracing meritocracy, allowing people to realize their full potential. The nation can stay ahead in a fast-paced world because to pragmatism, which gives it the ability to quickly adjust and respond to changing circumstances. Integrity and honesty have created a foundation of trust that has drawn in international partners and fostered an environment that promotes development and innovation. Nevertheless, Singapore’s journey is still guided by the virtues of meritocracy, pragmatism, and honesty, which encourages other developing countries like Nepal to take note of its achievements and apply these virtues to their own situations.

No discussion about Singapore’s success and the MPH Formula would be complete without acknowledging the pivotal role played by the nation’s founding father, Lee Kuan Yew. Lee Kuan Yew, with his visionary leadership and unwavering commitment to his people, laid the groundwork for Singapore’s transformation into a global powerhouse. His strategic vision and relentless pursuit of excellence were instrumental in implementing the principles of meritocracy, pragmatism, and honesty that became the bedrock of Singapore’s development. Lee Kuan Yew’s bold and forward-thinking policies shaped Singapore’s economic landscape, attracting foreign investments, promoting education, and cultivating a culture of innovation. His unwavering dedication to good governance, integrity, and building strong institutions set Singapore on a trajectory of sustained growth and prosperity. Lee Kuan Yew’s legacy serves as an enduring inspiration not only for Singapore but for nations around the world, including Nepal, as we explore ways to apply the MPH Formula to our own context and unlock our nation’s true potential.

As Nepal looks to forge its own path toward development, it can draw inspiration from Singapore’s MPH Formula – Meritocracy, Pragmatism, and Honesty. By embracing meritocracy, Nepal can create a system that rewards talent and hard work, unlocking the potential of its people. Adopting a pragmatic approach will enable Nepal to adapt to changing circumstances, seize opportunities, and address its unique challenges effectively. Upholding honesty and integrity as fundamental values will lay a strong foundation of trust, attracting investments, fostering innovation, and promoting transparency in governance. While Nepal may face its own set of obstacles and context-specific considerations, the principles embedded in the MPH Formula can serve as guiding principles for a successful and sustainable development journey, empowering Nepal to create a prosperous and inclusive future for its citizens.

Microsoft’s Xiaoice vs Google’s Meena

Two of the most advanced conversational AI models created by these tech titans are Microsoft’s Xiaoice and Google’s Meena. These artificial intelligence (AI) systems can comprehend, process, and produce natural language text while simulating conversations with users that are similar to those of a human. Both Xiaoice and Meena have outstanding conversational performances thanks to their training on massive datasets of human talks. The specifics of these models, including their algorithms, capabilities, training datasets, development APIs, language support, and other information, will be covered in more detail in this article.

Introduction:

Microsoft’s Xiaoice is an AI-driven conversational chatbot that was created. It was initially introduced in China in 2014, and since then, it has spread to other nations. Xiaoice can provide responses that are identical to those of a human since it has been taught using vast amounts of conversational data from social media sites like WeChat. To comprehend user input and produce responses, it combines deep learning algorithms with natural language processing (NLP) strategies. As part of its “personality” concept, Xiaoice can modify its responses in reaction to the user’s emotional condition.

Meena is a conversational chatbot powered by AI that was created by Google. It was first released in 2020 and is made to resemble a person more than earlier chatbots. Meena’s main focus is on comprehending the context of a conversation and coming up with meaningful, interesting responses. Meena is highly suited for things like customer assistance and social interactions because it can handle lengthy chats.

Algorithm used

Recurrent neural network (RNN) is a deep learning method that is used by Xiaoice to produce answers. The ability to process sequences of input data makes RNNs an excellent choice for NLP applications like dialogue production. Sequence-to-sequence learning, which involves feeding the model pairings of input-output sequences, is the method used to train Xiaoice’s RNN. This enables Xiaoice to pick up on the recurring patterns and structures of human discourse and produce fluent, contextually appropriate responses.

Meena employs a “Transformer” neural network architecture, a kind of deep learning algorithm that was created by Google in 2017. Conversation generation and machine translation are examples of sequence-to-sequence learning tasks that can be handled by the Transformer architecture. Meena’s Transformer is trained through a method known as “retrieval-augmented generation,” which entails extracting pertinent data from a substantial knowledge base and utilizing it to produce contextually pertinent responses.

Abilities: What Xiaoice and Meena can do?

Xiaoice has the ability to hold natural language conversations with users about a variety of subjects, such as the weather, sports, entertainment, and interpersonal relationships. It has been used to assist individuals in coping with depression and other mental health difficulties and can also offer users emotional support. Xiaoice is capable of comprehending various accents and dialects, and it can even provide responses in various languages.

Meena is capable of engaging in long-form conversations with users and can handle a wide range of themes. It is intended to comprehend the context of a discussion and produce appropriate and interesting responses. Meena may also recognize the user’s emotional condition and modify its replies accordingly. Meena’s capacity to provide imaginative and open-ended responses is one of its main advantages, making it ideal for social situations and other conversational tasks.

Training Datasets

Massive volumes of conversational data from social media sites like WeChat were used to train the Xiaoice system. Voice and text-based dialogues are also included in the training data, giving the model access to a variety of inputs.

The “Meena Dataset,” a sizable collection of human conversations, on which Meena was trained, consists of more than 340 million discussion threads and over 40 billion words. The dataset was gathered from a number of places, including chat logs, internet forums, and social networking sites.

Development APIs

To incorporate Xiaoice into applications, Microsoft provides an API to developers. With Xiaoice’s natural language processing capabilities and the Xiaoice API, developers may create unique conversational experiences. C#, Java, Python, and Node.js are just a few of the programming languages that are supported by the API.

Meena does not yet have an official API from Google, but the model is accessible to developers via the TensorFlow library, an established open-source machine learning framework. TensorFlow provides a comprehensive range of tools and resources for constructing and training AI models, including tools for natural language processing and conversational AI.

Language Support

With intentions to add more languages in the future, Xiaoice presently supports Chinese, Japanese, and English.

Meena is able to comprehend and respond in a variety of languages, including Hindi, French, German, Spanish, and more.

Meena and Xiaoice are both outstanding conversational AI models, but there are some significant variations between them in terms of their techniques and capabilities. With the help of its “personality” and recurrent neural network, Xiaoice can adapt its replies to the user’s emotional state. Meena, in contrast, employs a transformer architecture and focuses on comprehending the context of a discussion in order to produce pertinent and interesting responses. Meena has a broad comprehension of language and conversation because it has been trained on a vast dataset of human talks and can handle long-form dialogues.

Modern conversational AI models like Microsoft’s Xiaoice and Google’s Meena have achieved outstanding results in terms of their capacity for natural language understanding and conversation production. The models were created to imitate human-like talks with users and were trained on vast datasets of human conversations. They both represent significant developments in the field of conversational AI and have the potential to fundamentally alter how we engage with technology, despite some differences in their methods and capabilities.

E-Sewa vs FonePay – Difference between PSP and PSO

Though both platforms named E-Sewa and FonePay are operated and controlled by the same company called F1 Soft, the purpose of these two applications is different.

Firstly you need to understand the concept of Payment Service Provider(PSP) and Payment Service Operators(PSO). Payment Service Operator(PSO) is the platform that acts as an intermediary to settle all the financial transactions of PSP who are using their network for the purpose of fund settlement and debit-credit routing related activities. PSO are platforms where Financial institutions such as banks, financial institutions, and payment service providers etc. can interlink for clearing and settlement of transactions. 

Fonepay is a digital payment processor that connects consumers, banks and merchants in an interoperable network to facilitate mobile/digital payments. According to F1 Soft, It is Nepal’s first mobile payment network to be licensed by the central bank as a Payment Service Operator (PSO).

Fonepay can be considered as a payment gateway like ConnectIPS which helps in connecting banks, consumers and merchants for settlement of their payments. FonePay allows various modes of online payment like B2B, B2C, C2B, C2C possible with all in one platform. Majority of  digital wallets used by Banks in Nepal rely on fonepay as F1 Soft is the dominant player in banking and online financial settlements in Nepal for a long time. Recently, we can see the emergence of other platforms like ConnectIPS.

On the other hand, A payment service provider is a third-party company that assists businesses to accept a wide range of online payment methods, such as online banking, credit cards, debit cards, e-wallets, cash cards, and more. They’re peer-to-peer platforms that ensure customers’ transactions make it from point A to point B, safely and securely.Renowned payment apps like Khalti and Esewa are PSPs. 

Timestamp ordering concurrency control technique – An introduction

A concurrency management method called timestamp ordering employs timestamps to arrange transactions and guarantee serializability. Each transaction is given a distinct timestamp when it is initiated, which is how it operates. When the transaction is finished being executed, the timestamp is used to rank it in relation to other transactions.

This is an illustration of how timestamp ordering functions:

  1. Transaction 1 begins, and a timestamp of 1 is put on it.
  2. Transaction 2 begins, and its timestamp is set to 2.
  3. Transaction 3 begins, and its timestamp is set to 3.
  4. Data that was written by Transaction 1 is read by Transaction 2.
  5. New data is written in transaction 1.
  6. The information that Transaction 1 wrote is read by Transaction 3.

The transactions in this example are carried out in the following succession: 1, 2, 3. This is due to the fact that the timestamps attached to each transaction show the chronological sequence in which they were initiated.

Here is a timestamp ordering algorithm:

  1. Give each transaction a special timestamp as soon as it begins.
  2. Check the timestamp of a transaction against the timestamps of other transactions that have accessed the same data when it tries to read or write data.
  3. Wait for other transactions to finish if the transaction’s timestamp is older than those of other transactions.
  4. Allow the transaction to execute if its timestamp is more recent than those of other transactions.
  5. Use the transaction’s timestamp to rank it in relation to other transactions after it has completed.

Two-phase locking technique in DBMS concurrency control – An Introduction

Two-phase locking is a concurrency control technique used in database management systems (DBMS) to ensure the serializability of transactions. Serializability is the property that ensures that the concurrent execution of transactions produces the same result as if the transactions were executed one at a time.

Two-phase locking is based on the idea of acquiring locks on data items before reading or modifying them, and releasing locks after the data has been read or modified. There are two phases in the two-phase locking protocol:

  1. Growing phase: During this phase, a transaction can acquire locks on data items, but cannot release any locks.
  2. Shrinking phase: During this phase, a transaction can release locks, but cannot acquire any new locks.

Here is an example of how two-phase locking works:

  • Transaction 1 begins and acquires a lock on data item D1.
  • Transaction 2 begins and tries to acquire a lock on D1, but is blocked because Transaction 1 has a lock on D1.
  • Transaction 1 releases its lock on D1 and acquires a lock on D2.
  • Transaction 2 acquires the lock on D1 and begins executing.

In this example, Transaction 2 is executed after Transaction 1, even though they were running concurrently. This ensures that the integrity of the database is preserved as if the transactions were executed one at a time.

Here is an algorithm for two-phase locking:

  1. Begin the transaction and enter the growing phase.
  2. Acquire locks on any data items that need to be accessed or modified.
  3. Execute the transaction.
  4. Release all locks and enter the shrinking phase.
  5. Commit the transaction.

Two-phase locking is a simple and effective concurrency control technique, but it can suffer from performance issues due to lock contention (when multiple transactions are trying to acquire the same lock).

Serializable schedule in DBMS transaction processing

In a database management system (DBMS), a serializable schedule is a way of executing concurrent transactions in a way that produces the same result as if the transactions were executed serially (one after the other). In other words, a serializable schedule ensures that the concurrent execution of transactions preserves the integrity of the database, as if the transactions were executed one at a time.

A serializable schedule is achieved through the use of locks, which are used to prevent multiple transactions from accessing and modifying the same data simultaneously. When a transaction acquires a lock on a piece of data, no other transaction can access or modify that data until the lock is released. This ensures that the transactions are executed in a serial fashion, even though they are running concurrently.

Here is an example of how a serializable schedule might work in a DBMS:

  • Transaction 1 begins and acquires a lock on data D.
  • Transaction 2 begins and tries to acquire a lock on data D, but is blocked because Transaction 1 has a lock on D.
  • Transaction 1 completes and releases the lock on D.
  • Transaction 2 acquires the lock on D and begins executing.

In this example, Transaction 2 is executed after Transaction 1, even though they were running concurrently. This ensures that the integrity of the database is preserved, as if the transactions were executed one at a time.

Transaction Control in DBMS – An introduction with examples

A transaction in a database management system (DBMS) is a piece of work done on a database. Because a transaction is an atomic unit, it can either be completed entirely or not at all. Desirable properties of Transaction in DBMS are commonly known as ACID properties.

The process known as transaction control enables you to govern how transactions affect your database. It enables you to either roll back the changes made during a transaction in the event of an error or commit the changes made during a transaction to the database.

Here I present you some examples of how transaction control is used in a DBMS:

  1. Transferring money from one bank account to another:

You can think of this as a two-step process:

  • Step 1: Deduct the money from the source account
  • Step 2: Add the money to the destination account

To make sure that the accounts remain in a consistent state, you would want to roll back the transaction if either of these stages fails.

  1. Updating a customer’s address in a database:

Consider updating a database with a customer’s address. There may be numerous tables where the address needs to be updated (e.g., the “customers” table and the “orders” table). To keep the database in a consistent state if one of the updates fails, you would want to roll back the transaction.

  1. Printing a report:

Consider printing a report that requires data queries from several different tables. You may want to roll back the transaction if the query fails for any reason in order to prevent the report from being generated with inaccurate or missing data.

These are just a few instances of how a DBMS uses transaction control.

Happy Learning!

ACID Properties of Transaction – Atomicity, Consistency, Isolation, Durability

Transactions in a database management system (DBMS) include a number of characteristics that guarantee the consistency and integrity of the database. The following are the so-called ACID properties:

  1. Atomicity: This characteristic makes sure that a transaction is an atomic unit, which means that it is either entirely finished or not at all finished. All changes performed during a transaction are undone in the event of an error, and the database is restored to its initial state.
  2. Consistency: This characteristic makes sure a transaction leaves the database in a state that is consistent. The sum of all accounts must remain unchanged, for instance, if money is being transferred from one bank account to another.
  3. Isolation: This characteristic makes sure that the modifications performed by one transaction are separate from those made by other transactions. This is crucial because it stops transactions from interfering with one another and makes sure that each one is handled as if it were the only one.
  4. Durability: This characteristic guarantees that changes made by a transaction are permanent and cannot be undone in the event of a system failure after the transaction has been committed.

These characteristics are necessary for any DBMS to operate properly and aid in preserving the database’s consistency and integrity.

Learning from Lord Shiva: Lessons for Technology Professionals on Maha Shivaratri

On the auspicious occasion of Maha Shivaratri, I Wish you Good Health and all the Happiness you deserve. May God Shiva bestow the Blessings of Energy, Courage, and Success to you and your family. Jay Pashupatinath!

I’m here with another blog post to highlight the learnings that everyone can learn from the personality of Lord Shiva. God Shiva is known for his diverse personality and names like “Devo ka Dev”, “Mahadev”, “Nilkanth”, “Shivaji”, “Maha Yogi” “Bholenath”, “Ardhanarishwar” and “Pashupatinath” etc. He is known as a destroyer of evil spirits and injustices. Some lessons that every technology fellow(programmer, designer, analyst, project manager, or whatever position they’re in) can learn from Shiva are listed below:

1. Tolerance and Self Control
Shiva is considered the optimum state of mind and the mind’s stability. Whatever situation we’re going through, we must control ourselves and think twice before action. Most of the time we become reactive instead of acting consciously. We should be able to handle our desires and addictions(if any) to win the battle. Focus is everything so you should keep your goal clear and your mind, as well as your heart, focused on it.

2. Research over Ignorance
Another thing you can learn from Shiva is to avoid ignorance as far as practicable. You might have seen “Ganga” flowing in Shiva’s hair which symbolizes the end of ignorance. Know the subject matter well before getting into it to be successful, be it in a project or any other task.

3. Desire, Obsession, and Destruction Theory
Unnecessary desires are the main reason behind obsessions. If your mind is thinking of an idea or there’s a thought that continually preoccupies or intrudes within, that may break your time schedules. It’s very important to stick with what’s important. The main thing must always be “The Main Thing”. Otherwise, it may lead you to a disastrous situation.

4. Respect Your Better Half
You may have seen lord Shiva’s images with half male(Shiva) and half female(Parvati). For this reason, he is also known as “Ardhanarishwar” – means half woman and half man. This symbolizes respect and cares for your counterpart. Every man should respect and care for women no matter what.

5. Materialistic Happiness is Temporary
Searching for happiness in the material world is not going to work in the long run. You need to find inner peace and a state of mind so that you can enjoy every moment happily. You can learn from Shiva’s outfit and appearance as well.

Maha Shivaratri can be considered a potent reminder of Lord Shiva’s teachings and qualities as the god of cosmic wisdom and enlightenment. His numerous influences on various facets of life are reflected in his diversified personality and naming patterns. One can gain a lot from Lord Shiva’s teachings as a technology expert, including tolerance and self-control, research over ignorance, want, obsession, and destruction theory, respect for your better half, and the fleeting nature of worldly satisfaction. We may improve ourselves and succeed in life by putting these teachings to work in both our personal and professional lives. On this auspicious occasion, let us seek Lord Shiva’s blessings and make an effort to aspire to his knowledge and teachings.

Happy Mahashivaratri!!!

Nepal’s Economic Diplomacy: Leveraging Trade, Investment, Tourism, and Overseas Employment

Hi everyone, welcome to DataSagar. Today, I would like to cover some crucial yet important facts and figures that every Nepali should be well aware of. In the meantime, some of you might be wondering what foreign diplomacy actually is.

When a nation uses diplomacy to advance its economic interests abroad and achieve its economic objectives, this practice can be referred to as economic diplomacy. It entails the use of diplomatic channels to negotiate economic deals, attract foreign investment, market travel/tourism, and strengthen international collaboration in such like infrastructure development and human resource management. Economic diplomacy, to put it simply, is a strategy used by nations to boost their economies and enhance the welfare of their populations.

As Nepal is well-known for both its burgeoning economy and its magnificent natural beauty. Nepal is a key actor in South Asia with a GDP of USD 33.6 billion and a GDP per capita of USD 1,191. Nepal has been actively participating in economic diplomacy, which is essential for fostering the country’s economic development. In light of international trade, foreign direct investment, tourism, government development assistance, and abroad employment, this article ought to examine Nepal’s economic diplomacy with a data-driven approach. Lets us begin with an idea of what our diplomacy is like from an economic perspective based on data, facts, and figures.

Foreign Trade:

Over the years, Nepal’s foreign trade has steadily increased. Nepal’s exports totaled NPR 1,41,124 million in 2020, compared to imports of NPR 15,39,837 million. About two-thirds of all trade between Nepal and its commercial partners are with India. The United States, Germany, the United Kingdom, and Turkey are among Nepal’s other main export markets. However, India, China, Argentina, the United Arab Emirates, and the United States are Nepal’s main import suppliers. To lessen its reliance on India, Nepal has been attempting to diversify its trading relationships. The nation has been looking into ways to expand its trade with Bangladesh, China, and other nations.

Foreign Direct Investment (FDI)

For Nepal’s economy to thrive, foreign direct investment (FDI) is a crucial source of funding. FDI worth 32 billion NPR was directed to Nepal in 2020. The top foreign investors in Nepal are from China, India, the United States, South Korea, and the British Virgin Islands. The government of Nepal has been providing numerous incentives to draw FDI, including tax breaks, profit repatriation, and streamlined investment procedures. To draw FDI, Nepal is boosting industries including hydropower, tourism, agriculture, and manufacturing.

Tourism:

One of the main drivers of Nepal’s economy is tourism. The nation is renowned for its stunning mountains, hiking routes, and culturally significant locations. Around 232,000 visitors visited Nepal in 2020, a sharp decline from the 1.2 million tourists Nepal had in 2019 before to the pandemic. Russia, China, the United States, the United Kingdom, and India are Nepal’s top tourist-producing nations. Through a number of steps, including granting visa-free travel to some nations, creating new trekking routes, and enhancing infrastructure, Nepal has been encouraging tourism.

Official Development Assistance(ODA)

For Nepal’s development programs, official development aid (ODA) is a significant source of funding. Nepal received USD 1,870,003,870 in ODA in the year 2020. The United States, the United Kingdom, China, India, and Japan are the main bilateral development partners, while the World Bank, the Asian Development Bank, the European Union, the United Nations, and GAVI are the leading multilateral development partners. In order to obtain funding for its development projects, the Nepalese government has been actively interacting with these development partners.

Foreign Employment

Many Nepalese laborers rely heavily on their income from outside employment. 166,698 Nepalese employees acquired new work visas or extensions to work abroad in 2020. Only two nations, Qatar and Saudi Arabia, which are countries where labor is sought after, have bilateral agreements with Nepal. However, Nepalese laborers are also employed in nations like the UAE, Bahrain, and Oman. The government of Nepal has been attempting to enhance the welfare and working circumstances of Nepalese workers abroad.

With all these, Nepal’s economic diplomacy has centered on maximizing its advantages in commerce, investment, tourism, official development assistance, and international employment. Nepal has been looking for ways to increase foreign direct investment (FDI), diversify its trade partners, promote tourism, secure more ODA, and enhance working conditions for Nepalese employees abroad. Nepal has the opportunity to profit from the economic rise of both China and India, thanks to our strategic placement between the two major economic giants. To fully achieve our economic potential, we must overcome a number of issues, including weak infrastructure, unstable politics, and a challenging business environment.

At the same time, we can’t deny the fact that the disastrous NepalQuake 2015 and COVID-19 pandemic has had a significant negative impact on Nepal’s economy, particularly the travel and remittance industries. The Nepalese government has been putting different steps in reconstruction as well as in place to lessen the pandemic’s negative economic effects, including aiding the impacted enterprises, promoting domestic travel, and increasing infrastructure spending. For Nepal to fully recover from all these and continue to prosper, our economic diplomacy will be of paramount importance.

Nepal’s economic diplomacy has been concentrated on utilizing its advantages and strengths to support economic development and prosperity. The government of Nepal has been aggressively collaborating with its allies to obtain funding to advance commerce, investment, tourism, and international employment. Although Nepal has a number of obstacles, its advantageous position, stunning scenery, and developing economy provide it with many chances for economic expansion and advancement.

Assertion in SQL – Basic

In SQL, an assertion is a statement that ensures that certain conditions are always enforced in the database no matter what. Same as domain or other constraints, assertions differ in the way that they are defined separately from table definitions. It is a named statement that defines a condition that must be true for the data in the database. If the condition is not met, the assertion will fail and the database will generate an error.

Here is the syntax for creating an assertion in SQL:

CREATE ASSERTION assertion_name
CHECK (condition);

For example, to create an assertion called “salary_assertion” that checks that no employee in the “employees” table has a salary greater than $100,000, you could use the following statement:

CREATE ASSERTION salary_assertion
CHECK (salary <= 100000);

We can create different assertions for specific conditions that must always satisfy in SQL. For example, the department_id attribute in manager relation is always not null since each manager works at least in one department. The following example shows an assertion named nomanager which checks that all the tuples in manager relation with department_id being NULL as not a manager.

CREATE ASSERTION nomanager

CHECK( NOT EXISTS
    ( SELECT * FROM MANAGER
    WHERE  Department_id is NULL));

Hence, the above assertion ensures that there is no manager who is not assigned any department at any time.

Another example can be the sum of all loan amounts for each branch must be less than the sum of all account balances at the branch. This can be satisfied by creating assertion as below:

     create assertion sum-constraint check
     (not exists (select * from
branch
                      
where (
select sum(amount) from loan
                              
where loan.branch-name =
                                                 branch.branch-name)
                              >=
(select sum(amount) from   account
                              
where loan.branch-name = branch.branch-name)))

To drop an assertion, you can use the following statement:

DROP ASSERTION assertion_name;

Assertions are useful for enforcing data integrity and ensuring that the data in the database meets certain conditions. They can be used to enforce business rules or to ensure the consistency of the data. However, they can also be time-consuming to create and maintain, so they are not always used in practice.

What is Metaverse? Are we very close to live in immersive digital world alongside physical world?

Hi everyone! So, here I’m with the hot topic for you that’s gaining popularity never like before- Metaverse! With excessive use of these terms by majority of news portals and tech websites recently, you might be thinking what actually is the metaverse?

Firstly, to understand fundamental about Metaverse, let’s dissect its word structure or say it syllable. Metaverse is a word which is combination of two words “Meta” which means beyond and “Verse” referring to Universe. So combinedly, it’s beyond what we see and feel in our very surrounding.

Well, to start, if we think of the internet as revolutionary technology than we might be known to the fact that lots of expert discussions are centered to Web 3.0, which is supposed to be the recent version of world wide web. We’re all familiar with world wide web(WWW) or say it just “web” and maybe some of us already delved into “web development” as well. What we were doing on web was just using playing with linear two dimensional constructs like images, texts, web pages, animations etc. And now, the metaverse is playing with spatial construct as opposed to the previous web. By saying space, it’s not just a game or entertainment stuff.

It’s blend of real universe with immaginary universe that is created collaboratively by independent users or organizations with the help of recent technological advancements like Augmented Reality(AR) and Virtual Reality(VR). We can refer metaverse as the latest and future version of the internet as well and so do the majority of tech giants.

Majority of general public believe that the idea behind metaverse is same as experiences that they gain by participating in the virtual gaming platforms with an avatar of self. FYI, avatar is a virtual version of ourselves that we control as we explore this entirely new online frontier.

Wait, but what will we actually do with avatars in metaverse? It it just like Social media with 3D avatars of people talking with each other and hanging out? That understanding is not wrong either but it’s not everything!

Technology world, regarding metaverse, is just in adoption and testing phase and some players are already working towards this technology to great extent. But, rather than confining our imagination just to what we’re seeing as metaverse right now, it’s better to imagine what the metaverse could be in future and how it’s going to change the way we’re connecting with friends and family as well as how businesses could leverage this technology and benefit in near future.

Metaverse is trying to build everything to be immersive and connect our physical existence with physical like virtual existence. By saying so, it doesn’t mean that everything has to be virtual reality. It could also just be on our smartphone or on a personal computer. You might have noticed that we’re using the tools of the metaverse to create a good portion of this items already. I spend a lot of time these days; first, trying to just define what the metaverse actually is. With the zeal of exploring this technology, I recently signed up to a metaverse platforms named “Oasis” and “Uhive” where I was given to create an avatar of mine and get involved with either VR headset or smartphone itself. Except for daily mundane routines of sleeping, getting up, eating, going to work, hangout with dear ones, whatever I wanna do, I can do it in the Oasis. Hanging around my favorite spots like cities, museums, auditorium, sea beaches etc., meeting new people and starting conversations or watching movies together for a while is just a little in these platforms.

Majority of platforms like these provide tools for people to create their avatars from the very scratch or from a profile photo that they’ve uploaded. This become the virtual version of user which travel between online experiences in any metaverse. Over time, as lot of users are investing time in such future digital world, what I’m most excited about is an economy involved in such platforms. I mean, digital economy is not just related to digital goods and engagement time but also services in an immersive environment to great extent. With my avatar, activities and habituality comes various things. I’m going to need a stylist maybe, unlock features to expand my limitless opportunities or have to earn or buy a virtual home space or so on.

A recent Bloomberg intelligence report believes that the market opportunity for the metaverse could be $800 billion by 2024.

Some tech giants like Microsoft has adapted its workplace meeting software teams for the metaverse already. They’re developing a system called mesh designed to work with a variety of different devices including virtual and augmented reality. Mesh is designed to operate on top of the real world that we live in, using headsets like Microsoft’s HoloLens or even with mobile phones.

During pandemic, we all have experienced online meetings and online classes never like before and what we all probably felt as participant of two dimensional flat video meeting was the low effectiveness or fatigued maybe. But with mesh, Microsoft realize they now on the verge of making communication to about less speech and more involvement with facial expressions, gestures and everything else.

With metaverse, I shall be in my living room with the entire team from different geographical location around the same table making eye contact along with all the gestures that are coming into the right place. That can change completely the way we do meetings and work in team. Its not limited only to these meeting things by the way. Metaverse isn’t just about seeing these virtual worlds and interacting via same tools we’re using now but about feeling them as well.

Facebook recently changed its company’s branding name as “Meta” to shift it’s focus towards metaverse and probably to dominate the market of VR the earliest possible. They’re working on Oculus VR Headsets affordability rapidly to take advantage as early adopters. Meta has also revealed that it’s been working on a glove that will let the user feel sensations like holding an object and touch/feel as well. The glove has a number of sensors that measure the wearer’s movements. On ethe other hand, air pockets managed across the glove surface inflate to create sensation as well. These gloves aren’t quite ready for prime time yet but they’re an indicator of the kind of research that’s going on behind the surface.

I think we are very-very close, and witnessing every day though, the exodus from a purely physical world to an increasingly immersive synthetic digital world that doesn’t look like one place we all go to, but it’s actually just the blend of the different digital worlds that we experience on our various devices.

There’s no doubt that Metaverse depicts a future internet of 3D immersive spaces linked into a spatial virtual universe, but universal technology standards, affordable and accessible interfaces, security and privacy as well as communication protocols between users, devices and among virtual environment systems are still in development phase.

Porter’s Value Chain Analysis for Hotel Industry

Michael Porter created a concept called value chain analysis to assist firms in identifying the processes that add value for stakeholders and customers. The model is predicated on the notion that organizations are made up of a variety of tasks carried out to develop, create, sell, provide, and support goods and services. Each step in the value chain presents a potential source of competitive advantage and a chance for businesses to streamline their processes and set themselves apart from rivals.

Porter’s value chain model can be used to pinpoint the actions that help create and deliver value to visitors in the hotel sector. Hotels can find areas where they can increase productivity, cut expenses, and improve the guest experience by evaluating the value chain. This can range from obtaining raw materials and controlling inventory to providing individualized service and preserving customer happiness. In the end, hotels may achieve their strategic objectives and acquire a competitive advantage in the market by optimizing their value chain.

Poeter’s framework aids in identifying the many tasks involved in producing value for clients in the hospitality sector is the hotel industry value chain analysis. Primary activities and support activities make up the value chain as described below.

PRIMARY ACTIVITIES:

  1. Inbound Logistics: including the receipt, storage, and distribution of supplies needed for hotel operations are referred to as inbound logistics. By streamlining the procurement process, technology enables the hotel to get goods and services at the lowest cost and with the quickest turnaround.

An example is a cloud-based procurement tool that a hotel may use to automate purchases, monitor inventory levels, and notify workers when it’s time to refill supplies.

  1. Operations: This refers to all of the tasks involved in maintaining a hotel operational, including housekeeping, front desk duties, food and beverage services, and maintenance. Technology contributes to value creation by streamlining operations, cutting costs, and raising service standards.

With an automated housekeeping management system, for instance, a hotel can speed up response times and enhance client satisfaction by enabling housekeepers to manage room cleaning requests from a mobile device.

  1. Outbound logistics: These are all the tasks involved in providing guests with the hotel’s goods and services. By allowing the hotel to deliver goods and services swiftly and effectively, cutting expenses, and raising customer happiness, technology aids in value creation.

A hotel might employ a digital concierge service that enables visitors to use their mobile device to buy room service, make reservations at restaurants, and arrange tours and other activities. This would cut down on wait times and enhance the guest experience.

  1. Marketing & Sales: All of the activities involved in promoting and selling the hotel’s goods and services fall under the category of marketing and sales. By allowing the hotel to reach a larger audience, customize marketing campaigns, and boost revenue, technology aids in value creation.

Using a customer relationship management (CRM) system, for instance, enables a hotel to gather and examine guest information, customise marketing messages, and assess the success of marketing efforts.

  1. Service: This refers to all actions taken to give visitors excellent customer service while they are visiting. By improving the guest experience, cutting down on wait times, and raising customer satisfaction, technology aids in value creation.

A hotel can employ a platform for guest engagement, for instance, that enables visitors to interact with staff via a mobile device in real-time, making personalized recommendations and quickly resolving any difficulties. This promotes client satisfaction and the guest experience.

SECONDARY ACTIVITIES:

  1. Procurement: This refers to any actions taken in connection with obtaining the items and services necessary for hotel operations. By automating the procurement process, cutting expenses, and increasing efficiency, technology contributes to value creation.

An example is a cloud-based procurement tool that a hotel may use to automate purchases, monitor inventory levels, and notify workers when it’s time to refill supplies.

  1. Technology development: This term refers to the actions involved in creating and maintaining the technological infrastructure needed to run a hotel. By increasing productivity, cutting costs, and improving the guest experience, technology aids in value creation.

A property management system (PMS) can be used by a hotel to integrate all of its operations, from front desk work to housekeeping, allowing staff to run the establishment more effectively and enhance the visitor experience.

  1. Human Resource Management: Management of human resources comprises all actions taken to oversee the staff at the hotel. Through increasing productivity, lowering expenses, and increasing employee happiness, technology aids in value creation.

The hiring process may be automated, employee performance can be tracked, and employee benefits can be managed using a cloud-based human resource management (HRM) system, for instance, which increases productivity and lowers administrative expenses.

  1. Firm Infrastructure: This refers to all operations involved in maintaining the hotel’s physical assets, such as its buildings, machinery, and facilities. By increasing productivity, cutting costs, and improving the guest experience, technology aids in value creation.

The deployment of a smart building management system by a hotel, for instance, can lower energy costs and enhance visitor satisfaction by monitoring and controlling energy use such as Heating, ventilation, and air conditioning (HVAC) operations, lighting, and security.

Top 10 Free Code Editors for Web Developers in 2020

Hello everyone I’m here to share my list of the top 10 code editors for web developers with you folks. As web development is a profession that is always changing, having the appropriate tools at your disposal can significantly increase your productivity and efficiency. A code editor is one of the most essential tools for a web developer. Software that aids in writing and editing code is known as a code editor. It offers tools for debugging, code completion, and syntax highlighting. It can be challenging to decide which code editor to use because there are so many choices. We’ll examine the top 10 code editors for web developers in this article.

1. VS Code
Visual Studio Code, also referred to as VS Code, is the first editor on this list. It is a source-code editor created by Microsoft Corporation for the Windows, Linux, and Mac Operating Systems. Microsoft created Visual Studio Code, a free and open-source code editor. Due to its sophisticated features, like IntelliSense, which offers intelligent completions based on variable types, function definitions, and imported modules, it is one of the most well-liked code editors among web developers. Debugging support, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git are among the features. The theme, keyboard shortcuts, options, and extensions that offer more functionality can all be changed by users. If you haven’t, I highly suggest giving it a shot.

2. Atom
The second code editor on the list is Atom, a text and source code editor for macOS, Linux, and Microsoft Windows that supports JavaScript plug-ins and has incorporated Git Control. Another open-source, free code editor that is very customisable is called Atom. It is created by GitHub and has a sizable user and contributor community.

Facebook Down for 6 hours ― everything you need to know

Facebook family of apps gone through a rare yet lengthy outage on Monday’s night and cost of this technical glitch is getting reflected everywhere. With a day outage in 2008, 14 hours outage in 2019 and now for almost 6 hours, it seems that Facebook is gradually loosing control from their technology and downtime control. According to Facebook, cause of recent outage was faulty system configuration which took their team hours to resolve.

Facebook recently published a blog explaining what was happened and apologized for inconvenience. Facebook’s Official Blog writes,

To all the people and businesses around the world who depend on us, we are sorry for the inconvenience caused by today’s outage across our platforms. We’ve been working as hard as we can to restore access, and our systems are now back up and running. The underlying cause of this outage also impacted many of the internal tools and systems we use in our day-to-day operations, complicating our attempts to quickly diagnose and resolve the problem.

According to their official blog, they did experienced problems in tools and other technologies inside company that made the problem solution even more complicated.

“Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt.”

According to Facebook, they also have no evidence that user data was compromised as a result of this downtime.

Facebook and WhatsApp did apologized on Twitter and writes,

CTO Mike Schorepfer on Twitter writes,

Along with billions of daily active users, businesses as well as investors seems to gradually loosing trust over this tech giant. Recent outage cost in billions for the company as well and reports are coming from around the world stating that their market value seems declining as well.

According to forbes, their shares gone down by 4.8% and zapping away billions from CEO Mark Zuckerberg’s fortune. To be exact, Zuckerberg’s net worth declined by $5.9 billion in total.

With this huge loss from his net worth, he has also slipped from 5th richest person to 6th richest person in the world billionaires list.

Agile Software Process Model – An Introduction

Concept of agile software development

Agile is a software development model that encourages the continuous iteration of development and testing in the entire software development lifecycle of the project. It’s a modern approach in Software Development in which requirements and solution evolve through the collaborative effort of self organizing and cross-functional team along with their customers or end users. It is related to the method of project management, used especially for software and web apps development, that is characterized by the division of tasks into short chunk of work and frequent reassessment and adaptation of plans.

Image: Advantages of Agile Model | Source: hachinet

In agile approach, which is guided by the Principles of Agile Manifesto, both the development as well as testing activities are concurrent. Majority of documentation tasks like that in waterfall and prototype models are avoided and every activities in this model move very fast. Product development traverse through activities like Requirements Collection, Planning, Design and Development, Testing, Release and Monitoring very fast in this model of software development.

IN AGILE MODEL, values are delivered to customers in small increments onE after another where they get time and chance to experience it and provide feedback right away.

Key Point to Remember

As inputs and requirements from all the stakeholders as well as executives, customers, end users and team as a whole are collected, process proceed by gathering all the high level(Generic) requirements and features in one place. The initial list of high level requirements are referred to as epic. Epic is nothing other than collection of client’s organizational/business needs.
For example: As a teacher,
I’m having difficulty in managing students attendance and I need an application that can be used in classroom for students attendance management.

(Above need can be taken as an example of epic. It only address “why?” part of software development and cover huge requirement.)

Collected epic is further divided into workable chunks of functional categories which are referred to as stories. Collection of stories form epic, means that stories are nothing other than decomposition of high level requirement into parts or collection of features. From the example of epic depicted above, clients or customers need can be presented in form of stories.
For example: As a Teacher,
Story #1. I should be able to login to system
Story #2. I can view students details
Story #3. I can filter student information weekly, monthly, quarterly and yearly.

(Above 3 stories make team clear on “what?” part of the process. i.e. What actually the customer need as features of software that is going to be developed.)

Stories are further decomposed to narrow scope of actions and referred to as tasks. There may be numerous tasks in single activity. Tasks are collection of well defined actions that development and quality assurance team perform on daily basis. So mainly two varieties of tasks Development Tasks and Quality Assurance Tasks are prepared here. From the story #1 above, we can divide actions and define the tasks/solutions.
For example,
Development Tasks to carried out in Login System can be
1. Review the requirement and Estimate
2. Design and Code
3. Unit and Integration Testing

Development Tasks to carried out in Login System can be
1. Review Story
2. Develop Test case, plan test scenario, gather test data
3. Set up the test environment
4. Execute Test and Report bugs if there’re any

(This gives a clear picture of “how?” part of software process, i.e. features that are to be developed and tested by team.)

What is Scrum?

Another part in Agile Software Process is framework for software process. Framework defines how team work to develop system in collaborative manner actually. Some frameworks that are guided by Agile philosophy includes Extreme Programming(XP), Rapid Software Development(RAD), Scrum, Feature Driven Development(FDD), Lean Method, Crystal Method etc. Among them, Scrum is one of the most popular Agile methodologies as of today. In short, all Scrum projects incorporate Agile philosophy, but not all Agile projects necessarily use the Scrum.

Agile Scrum Roles:

Scrum Master Facilitates the overall process. He/she encourage, facilitate, reflect, share, reward and protect whole team. Main role is to guide the project team and the product owner during the development phase and ensures that the team is implementing all the required agile practices properly.
Product Owner Get requirements from clients, define features, decide release date, prioritize features, modify features as per need, and accept or reject results. Their main role is to interconnect client/business part with the development team.
Scrum TeamInclude Development Professionals(designers, architects, engineers etc.) and Quality Assurance professionals. Their main role is to transform the client’s needs to working system.

Definition of Ready(DOR) and Definition of Done(DOD): List of prerequisites / conditions by satisfying which story or task are considered either ready for test or done.

Fig: Agile Scrum Framework of Software Process | Image: Tuleap

How agile scrum team work?

With the input from executives, team, stakeholders, customers and users of system, Project Owner list clients epics and stories to create list of features called as Product Backlog. Product backlog contains all the requirements of customer.

Whole team(Owner, Developers, Testers, Scrum Master) sit on a meeting to plan for the estimated delivery of each features or user stories based on priorities and feasibility. Development team and QA team give some estimation point(usually a random number of days like 1,2,3,5,8,13,.. etc.) to collected client stories. Based on these estimations, Whole project development time is sliced into small fractions where group of actions are performed and each chunk is referred to as sprint. Sprint is a term that refer to a short time period or iteration(usually of 2 weeks to 1 month) during which new features are designed, developed, tested and incremented into project as a release. Sprint plan made in participation of development and QA team is often referred to as Sprint Backlog.

Developers and QAs write their own task for each stories and execute task actively in collaborative manner. Though sprint time may be of 2 weeks to 1 months, team meet everyday to report status of last as well as next activity and blockages(if any).

Team uses varieties of software management tools to track and monitor activities, deliverables, releases and overall status of software process. We, at illionSo Technologies, are using Scrum Boards(excessively) as well as Kanban Boards(rarely) to track agile process activities. We do use project management tools like Jira – for medium scale software development and Trello – for web project management.

Windows Memory Integrity – How to protect your Core system data in windows

Memory integrity is a security feature in the Windows operating system that helps prevent malicious code from tampering with system memory. This feature is designed to protect critical system processes, kernel-mode drivers, and system memory pages from tampering, which can lead to serious security vulnerabilities.

Memory integrity was first introduced in Windows 10 Creators Update and is now an essential component of the Windows security platform. It operates by restricting access to system memory to only trusted processes, drivers, and memory pages. This is achieved by assigning system memory pages with a special security attribute known as “write-protected.”

This feature helps prevent various types of attacks such as buffer overflow attacks, where an attacker attempts to write past the end of a buffer and overwrite critical data in memory. Memory integrity also helps prevent other types of memory-based attacks, such as rogue processes that inject malicious code into the memory space of other processes.

Memory integrity operates by using hardware-based virtualization technology, specifically hardware-enforced memory integrity. This technology creates a virtualized environment for system memory, where the hardware can enforce memory protection policies without the need for software-based solutions.

In order to take advantage of memory integrity, Windows requires compatible hardware, specifically processors that support hardware-based virtualization technology. Most modern processors support this technology, but it is important to check if your device meets the minimum requirements before enabling memory integrity.

To enable memory integrity in Windows, you can use the Windows Security app. To do this, simply open the Windows Security app, go to the “Device Security” section, and turn on “Core isolation details.” From there, you can enable memory integrity, as well as other security features, such as system firmware protection and virtualization-based security.

In conclusion, memory integrity is an essential security feature in Windows that helps protect your system against memory-based attacks. By restricting access to system memory to only trusted processes and drivers, memory integrity helps prevent malicious code from tampering with system memory and compromising the security of your device. Whether you’re a home user or a business, it’s important to take advantage of this feature to ensure the security of your system and data.

SET operations in SQL

Set operations combines the results of two independent SQL queries. There are three set operations in SQL 

1.Union

2. Intersect

3. Except

These set operations operate on relations and are based on the general principles of mathematical set theory that you’ve probably covered in school level math. 

One thing to not forgot is, each of these operations automatically eliminates duplicates in the result. In order to retain all the duplicates, one can use the corresponding multiset versions of basic set operations union all, intersect all and except all.

Suppose a tuple/row occurs m times in a relation named r and n times in relation named s then it occurs

m  + n times in r union all s

min(m,n) times in r intersect all s

max(0, m – n) times in r except all s.

Some example queries are shown in image below:

The relation schemes for all the examples used above are:

Branch(bname, bcity, assets)

Customer(cname, street, ccity)

Depositor(cname, account#)

Account(bname, account#, balance)

Loan(bname, loan#, amount)

Borrower(cname, loan#)

Joins in SQL

With SQL, there are various JOIN types that let you combine data from different tables. Below is a quick summary of the most popular JOIN kinds and their syntax:

INNER JOIN: An INNER JOIN returns only the rows that match the join condition in both tables.
Syntax:

SELECT *
FROM table1
INNER JOIN table2
ON table1.column = table2.column;

Example:

SELECT employees.id, employees.name, department.name
FROM employees
INNER JOIN departments
ON employees.department_id = departments.id;

LEFT JOIN (or LEFT OUTER JOIN): A LEFT JOIN returns all rows from the left table (table1), even if there is no match in the right table (table2).
Syntax:

SELECT *
FROM table1
LEFT JOIN table2
ON table1.column = table2.column;

Example:

SELECT employees.id, employees.name, department.name
FROM employees
LEFT JOIN departments
ON employees.department_id = departments.id;

RIGHT JOIN (or RIGHT OUTER JOIN): A RIGHT JOIN returns all rows from the right table (table2), even if there is no match in the left table (table1).
Syntax:

SELECT *
FROM table1
RIGHT JOIN table2
ON table1.column = table2.column;

Example:

SELECT employees.id, employees.name, department.name
FROM employees
RIGHT JOIN departments
ON employees.department_id = departments.id;

FULL JOIN (or FULL OUTER JOIN): A FULL JOIN returns all rows from both tables, even if there is no match in either table.
Syntax:

SELECT *
FROM table1
FULL JOIN table2
ON table1.column = table2.column;

Example:

SELECT employees.id, employees.name, department.name
FROM employees
FULL JOIN departments
ON employees.department_id = departments.id;

Data from different tables can be combined using JOINs if they share a column or collection of columns. They are a crucial component of SQL and are commonly used in reporting and data analysis.

View in SQL

A virtual table called a SQL view is produced as a result of a SELECT command. It doesn’t save any data on its own; instead, it presents data from one or more tables in a certain fashion.

Syntax for creating a view in SQL:

CREATE VIEW view_name AS
SELECT column1, column2, ...
FROM table_name
WHERE condition;

For instance, you could use the following sentence to create a view called “employee_view” that displays all employees from the “employees” table with the last name “Smith”:

CREATE VIEW employee_view AS
SELECT *
FROM employees
WHERE last_name = 'Smith';

The same SELECT statement that you would use to query a table can also be used to query a view. For instance, you could use the following statement to get all rows from the “employee_view” view:

SELECT * FROM employee_view;

Views can be helpful for a variety of things, including:

  1. Query Simplification: Views can be used to divide down large queries into smaller, more manageable chunks, so simplifying them.
  2. Security: By limiting user access to the data that is displayed in the view, you can utilize views to limit access to certain data.
  3. Data integrity: Since views are built using SELECT statements, which are run each time a view is visited, you can make sure that the data displayed is always current by using views.

Assertion in SQL

An assertion in SQL is a named statement that specifies a requirement that must be true for the database’s contents. The assertion will fail and the database will produce an error if the condition is not satisfied.

The SQL syntax for writing an assertion is as follows:

CREATE ASSERTION assertion_name
CHECK (condition);

For instance, you could use the following sentence to establish an assertion called “salary_assertion” that verifies that no employee in the “employees” table has a salary more than $100,000:

CREATE ASSERTION salary_assertion
CHECK (salary <= 100000);

To drop an assertion, you can use the following statement:

DROP ASSERTION assertion_name;

Assertions can be used to enforce data integrity and guarantee that the database’s data complies with particular requirements. They can be applied to assure data consistency or to enforce business standards. They are not often used in practice though because they can take a lot of effort to make and maintain.

Trigger in SQL

An automatic execution of a defined block of SQL code known as a trigger occurs in reaction to specific events, such as the addition, modification, or deletion of a record in a table. Among other things, triggers are employed to uphold data integrity or to enforce business standards.

The SQL syntax for building a trigger is as follows:

CREATE TRIGGER trigger_name
AFTER/BEFORE INSERT/UPDATE/DELETE
ON table_name
FOR EACH ROW
BEGIN
-- trigger code goes here
END;

For instance, you could use the following sentence to build a trigger called “update_salary_history” that updates the “salary_history” table anytime an employee’s salary is updated in the “employees” table:

CREATE TRIGGER update_salary_history
AFTER UPDATE OF salary
ON employees
FOR EACH ROW
BEGIN
INSERT INTO salary_history (employee_id, salary, update_date)
VALUES (OLD.employee_id, OLD.salary, CURRENT_TIMESTAMP);
END;

To drop a trigger, you can use the following statement:

DROP TRIGGER trigger_name;

Triggers can be helpful for automating specific processes or maintaining data integrity, but they can also be difficult to build and manage, so they should only be used in limited circumstances. In general, it is a good practice to utilize triggers sparingly and to substitute other methods, including foreign keys and stored procedures, whenever possible.

Things to care about when designing a good database system

There are several things to consider when designing a good database system:

Data modeling: A good database design begins with careful data modeling. This involves identifying the entities (e.g., customers, orders, products) and the relationships between them, and then creating a data model that represents these entities and relationships.

Normalization: Normalization is the process of organizing a database in such a way that it meets certain goals, such as minimizing redundancy and dependency. A properly normalized database is more efficient, flexible, and easier to maintain.

Data integrity: Data integrity refers to the accuracy, completeness, and consistency of the data in a database. It is important to design a database that ensures data integrity through the use of constraints, triggers, and other mechanisms.

Performance: A good database design should take into account the expected workload and optimize the design for good performance. This may involve the use of indexes, partitioning, and other techniques.

Security: A good database design should include measures to protect the data from unauthorized access and tampering. This may involve the use of passwords, access controls, and encryption.

Scalability: A good database design should be able to handle an increasing workload without experiencing performance degradation. This may involve the use of sharding, replication, and other techniques.

Maintainability: A good database design should be easy to maintain over time. This may involve the use of good naming conventions, documentation, and other best practices.

Overall, a good database design should balance the needs of the application with the principles of good database design in order to create a system that is efficient, flexible, and easy to maintain.

Normalization basics that every DBMS student must know.

Normalization is a process that is used to reduce the redundancy and dependency in a database. It is the process of organizing a database in such a way that it meets two main goals:

Minimize redundancy: Redundancy occurs when the same information is stored in multiple places in the database. This can lead to inconsistencies, as different copies of the same data may not be kept in sync. Normalization helps to eliminate redundant data and ensure that each piece of data is stored in only one place.

Minimize dependency: Dependency occurs when one piece of data depends on another piece of data. For example, if an employee’s salary is stored in a separate table from their personal information, the salary depends on the employee’s personal information. Normalization helps to minimize dependency by breaking up large tables into smaller ones and establishing relationships between them using keys.

There are several different types of normalization, each of which has its own set of rules for organizing a database. The most common types of normalization are:

First normal form (1NF): A table is said to be in 1NF if it satisfies the following rules:
Each column must contain a single value (i.e., no repeating groups)
The order of the columns does not matter
There must be a primary key (a unique identifier for each row)


Second normal form (2NF): A table is in 2NF if it is already in 1NF and all of its columns depend on the primary key. In other words, no column should depend on a part of the primary key; it should depend on the whole key.

Third normal form (3NF): A table is said to be in 3NF if it is already in 2NF and all of its columns are independent of each other. In other words, no column should depend on any other column except the primary key.

Boyce-Codd normal form (BCNF): A table is in BCNF if it is already in 3NF and every determinant (a column or set of columns that determines the value of another column) is a candidate key (a unique identifier that could potentially be used as the primary key).

Normalization is an important concept in database design because it helps to ensure that a database is organized in a way that is efficient, consistent, and flexible. It can also help to improve the integrity and security of a database by reducing the risk of data inconsistencies and unauthorized access.

Two Tier vs Three Tier Database Management System Architecture

In the field of Information Technology, DBMS architecture can be defined as integrated combination of security standards for setting as well as programming aspect of databases along with the functioning or operating mechanism of existing structures. Architecture mainly focuses on the overall design and construction of database for large enterprise database systems that so as to manage massive amounts of information for organizations. DBMS Architecture helps in design, development, implementation, and maintenance of a database to great extent. To understand database architecture, we must understand how users of modern day applications interact with information stored in large enterprise environmental settings.

As we’re known to the fact that most users of a database system today are not present at the site of system that’re using them. Databases are connected to it through computer network. Remote machines on which database user work can be referred to as client machines. On the other hand, database system runs on machines called as servers. On the basis of design of system, DBMS architecture can be of either Centralized or Decentralized or Hierarchical type. Whatever it be, DBMS architecture can be seen as either a single-tier or multi-tier. Number of tiers depends upon the specific application requirements or how organizations implement their business logic.

There’re mainly 3 types of DBMS architectures:
1. Single/One Tier (1-Tier)
2. Two Tier Architecture (2-Tier)
3. Three Tier Architecture (3-Tier)

Fig: Single – Tier Architecture
Image Source: Research Gate

Single Tier database architecture is a simplest architecture with all the client, server and database residing on single machine. This very architecture is considered as rarely used architecture and is used by database learners in their local machine itself.
For example: If you install local servers like XAMPP or WAMPP or MAMPP etc. in your PC with MySQL and start learning SQL queries from your web browser, it can be considered as 1 – Tier architecture.

Fig: Two-Tier architecture.

Two Tier database architecture is the one in which whole system is divided into presentation layer and data layer where presentation as well as application layer run on the client devices and database reside on the server computers. It is also known as client-server architecture. In this architecture, the database management system resides on a server computer that is more powerful machines capable of providing service to many clients at once. Application Program Interface(API) standards like ODBC(Open Database Connectivity) and JDBC(Java Database Connectivity) are used for interaction between the client and the server. For this purpose, client first sends connection request to server machine and connection is established after server response. As database and end users are located in different sites, this architecture is considered as secured as well.
For example: Contact Management System created using MS- Access can be considered as an example of Two Tier architecture. Also, Applications like Microsoft Word or PowerPoint running on college’s local servers and students using those applications can be considered as 2-Tier.

Fig: Three – Tier Architecture

Three Tier database architecture is the one in which Presentation layer, Business Logic Layer and Data Layer are separated from each other. The client device acts as merely a front end and does not contain any direct database calls. Instead, the client communicates with a tier where all the business logics are implemented called application server. Clients usually interact with application server through a forms interface. Application server on the other hand communicates with a database system to access data. The business logic of the  application, which says what actions to carry out under what conditions, is embedded in the application server, instead of being distributed across multiple clients. Three – Tier applications are more appropriate for large applications, and for applications that run on the World Wide Web especially.
For example: Travel destination listing website www.nepaltourismhub.com hosted on internet, E-banking service provided by Sanima Bank etc.

I hope you understand the basic behind DBMS architectures and their use cases.

Anatomy of Corona Virus and science behind it

What is Corona Virus?

With common names Coronavirus, COVID-19, Sars-Cov-2 or SARS, etc. Coronavirus is an RNA Virus. Genetic signature inside this virus is made up of Rhino Nucleic Acid(RNA) which can replicate/reproduce itself. Its surface is covered by capsule and elongated structural extensions are seen known as spikes. These spikes form a crown-like structure which is the reason behind its name CoronaVirus. Starting from the year 2019, it created disease and mass penetration and called by the name COVID-19. World Health Organization recently named in accordance with the scientific nomenclature scheme of this category of species as SARS-Cov-2 which means that it’s generation 2 daughter virus of SARS.

How does it enter the human body?

Salival droplets from an infected person with nanoparticles of the SARS-Cov-2 virus go into any surface and hand or any body surface. If it gets a chance to enter the lung, it simply hijacks the protein receptors called ACE2 receptors residing on the surface of human body cells. The main thing is that these receptors are mainly dense in the alveoli cell of lungs from where gas exchange occurs which we call oxygenation. These ACE2 receptors protect lung tissues from injury.

How coronavirus affect our body function?

Coronavirus uses its spikes to communicate with ACE2 receptors and take advantage of the cell itself and use the entire cell as a reproduction factory.

As it replicates, it overtakes protective ACE2 receptors in alveoli. The thickening of the walls and fluid inside alveoli prevents the gas exchange and condition we call is Acute Respiratory Distress Syndrome (ARDS). Fibrosis takes place after that which results in scars within the lungs.
This condition results in no longer oxygenation inside the lung and our body fights back to take this over which we refer to as Severe Acute Respiratory Syndrome (SARS). SARS itself is dangerous as the rest of the body part can’t get enough oxygen to function and leads to multi-organ failure in most of the cases. This happens mainly in alveoli but the fatality ratio is high for a host with Cardiovascular Diseases, Diabetes, Chronic Respiratory Syndrome, High Blood Pressure, and Cancer, etc in prior in accordance with data from WHO.

For Your Information, Fibrosis is a pathological wound healing in which connective tissue replaces normal parenchymal tissue which leads to remarkable tissue remodelling followed by the formation of permanent scar tissues.

Clinical effects of SARS.

Clinical reportings from around the globe are seeing severe hypertension and low potassium in the blood as some signs from coronavirus affected patients.

How deadly is coronavirus?

The ability of a virus to spread from one host to another is referred to as the spreading factor for that specific virus. The spread factor for coronavirus is reported to be 2.6. For example, if 5 people have coronavirus and they infect 2.6 others then after 2 cycles 18 peoples could get infected. After 3 cycles, it could easily reach 52 people and make 140 people sick in a span of 4 cycles. Majors suggested by the majority of nations fighting against this virus to be in self-isolation and social distancing. This major flattens the exponential growth curve and help medical workers deal with current cases.

How soap help in breaking the chain?

The anatomy of viruses is completely different than that of bacterias. This is the reason that antibacterial soaps are not effective in killing the virus. Coronavirus has a fatty protein layer as an envelope that can only be penetrated by detergents like shampoo, dishwasher soaps, soaps, etc. These detergents act as a surfactant and pull out viruses attached in hand or even face surface. The soap has the ability to crack the outer surface of coronavirus, which means the ability to kill them. For this to happen, one should rub each and every corner of their hand for at least 20 seconds.

I hope you got the proper information about what novel coronavirus is and it’s basic structural information in layman’s term. If you liked the information, help spread this message so that everyone gets exact information about the cause behind this novel pandemic. Stay Safe!

Microsoft Promoting Free use of Teams Communication App Amid Coronavirus Breakdown

Microsoft Teams is a hub for teamwork to keep all your team’s chats, meetings, files, and apps together in one place. Instead of meeting in-person, this team communication and file-sharing application is a means for individuals and businesses to facilitate communication regardless of their geographical location. It’s even getting attention more than before the corona virus breakdown.

Microsoft’s executive vice president and president of global sales, marketing and operations Mr. Jean-Philippe Courtois announced six months’ use of Teams for free earlier this month via his Tweet.

Tech giants around the world are announcing free use of such communication applications one after another. Recently, Atlassian let their Jira and bunch of other team management tools free with some limitations to help people communicate to reach others in this global crisis. It’s not the sole purpose as well. As tech enthusiast we can spot some marketing strategy as well. One after another, they’re rolling out their software for general public and small businesses, there’s also an opportunity to such strategic decisions.

After Microsoft announced the Teams for free, it’s usage in China hiked up to result in a server crash recently. Corporate vice president for Microsoft 365 Mr. Jared Spataro recently announced that they’ve seen a 500 percent increase in Teams meetings and conferences there in China since January 31 as well as a 200 percent increase in Teams usage on mobile devices.

Leap Year in C, C for beginners

According to the definition, a year that is divisible by 4, 100 and 400 is known as a leap year. Also if a year is exactly divisible by 4 but not by 100 then it is also a leap year. Another important thing you must note is, if a year is exactly divisible by 4 and 100 but not by 400 then it is not a leap year. Based on this general understanding, we’ll build a programming logic to determine if a year entered by the user is leap year or not. We’ll also discuss how to print leap years between some range in this article.

1. Program to check whether a year entered by the user is leap year or not in C.

#include<stdio.h>
void main()
{
    int yr;
    printf("Enter year: ");
    scanf("%d",&yr);
    if(yr % 4 == 0)
    {
        if( yr % 100 == 0)
        {
            if ( yr % 400 == 0)
                printf("%d is a Leap Year", yr);
            else
                printf("%d is not a Leap Year", yr);
        }
        else
            printf("%d is a Leap Year", yr );
    }
    else
        printf("%d is not a Leap Year", yr);
 getch(); // for MS DOS based compilers like Turbo C
}

2. To print leap years in-between range of years provided by the user in C.

#include <stdio.h>
int main()
{
	int year1, year2, i;
	printf("Enter the Starting year: ");
   	scanf("%d", &year1);
	printf("Enter the Ending Year: ");
   	scanf("%d", &year2);
	printf("Leap Year between %d and %d are as below:\n",year1,year2);	
	for(i=Year1; i <= year2; i++){
		if( (0 == i % 4) && (0 != i % 100) || (0 == i % 400) ){
		    printf("%d\n", i);
		}
	}
    getch(); // for MS-DOS based compilers like Turbo C
}

Here, in the code portion

for(i=Year1; i <= year2; i++){
         if( (0 == i % 4) && (0 != i % 100) || (0 == i % 400) ){
             printf("%d\n", i);
         }
     }

for each ith year starting from starting year entered by user(i.e. initial value of i) as year1, we need to check if the year i is leap year or not? If yes, print it and if not keep iterating around loop until and unless value of i become ending year.

Thank You!

Everything about ASCII in C

American Standard Code for Information Interchange(ASCII) is a standard of character encoding for electronic communication. ASCII codes are universally used as a way to represent text in computers, networking equipment, and other various types of devices like IoTs and HHDs, etc. 

Usually, ASCII codes are written in 8 bits binary notations in case of binary arithmetics to represent different characters including upper case and lowercase alphabets as well as special symbols.

To print the ASCII Code in C Programming language, you can use different ways.

  • Take a character from the user and print ASCII of it.
  • Print all ASCII values
  • Print ASCII values between some range.

1. Get Character from the user and print ASCII Value of that character

#include<stdio.h>
void main()
{
    int e;
    char character;
    clrscr();
    printf("\n Enter a character of your choice: ");
    scanf("%c",&character);
    e=character;
    printf("\n The ASCII value of the character you've entered is : %d",e);
    getch();
}

One thing you should always consider while playing with ASCII is that the ASCII values of all the characters will be between 0 and 255. That’s why we need to use a loop starting at 0 and iterating up to 255 to print all characters in range 0 to 255.

For example, the following is the ASCII Table that shows ASCII of different characters and their equivalent values in a different number systems.

Below is a table for non-printable ASCII Characters.

2. To print ASCII of all characters and symbols

#include <stdio.h>
void main()
{
  int e;
  for(e = 0; e <= 255; i++){
    printf("The ASCII value of %c = %d\n", e, e);
   }
  getch();	
}


At the point when value of e is 65, it will print
The ASCII value of A = 65

3. To Print ASCII of characters in the range, one shall go with the following idea.

#include <stdio.h>
void main()
{
  int e;
  for(e = 65; e <= 90; i++){
    printf("The ASCII value of %c = %d\n", e, e);
   }
  getch();	
}

To print UPPER CASE english alphabets.
#include <stdio.h>
void main()
{
  int e;
  for(e = 97; e <= 122; i++){
    printf("The ASCII value of %c = %d\n", e, e);
   }
  getch();	
}



To print lower case english alphabets.

COVID-19 | Serious Lesson for Humanity

African countries are now imposing restrictions on visitors from European countries in a row as the majority of #COVID19 confirmed cases were found to be transported by travelers from Italy, Germany & other European countries.

Let’s not play blame game between nations and uplift conspiracy theories spread all around the world. There seems to be a race of powerful nations like the United States and China to adjust them in the new world order and probably be its leader which is very bad for the entire humanity and our existence on this planet.

There is no doubt that #Corona has flipped out the situation led by #Ebola epidemic in 2014 and is teaching us a powerful lesson that pandemics have nothing to do with ethnicity, geography or nationality. We are one!

Corona Virus Nepal Updates| Is Nepal Safe to Travel?

According to WHO, Latest figures on coronavirus outbreak shows that the worldwide number of infections reaches 87,614 as of March 3 and death toll climbed to 2,994.

Following is the latest map covering all the affected countries, deaths and successful recovery worldwide. All data are from WHO.

Following the risk assessment by WHO, which indicated Nepal among the top nations with a high chance of virus spreads, Nepal Government has given a sign that a promotional campaign for Nepal Tourism Year 2020 will be focused more on domestic tourism more than foreign tourists as a strategic move to fight against the Novel Corona Virus outbreak that is spreading throughout the world. Talking about Nepal, the confirmed case is only one though being a neighbor nation of China. The majority of tourists planning to visit Nepal started to raise questions on the current status of this novel disaster and Is Nepal safe to travel during the Novel Corona Virus outbreak? and so on. Below is the live chart highlighting Nepal. Nepal’s Current Status on Corona Disaster Extracted from open data platform by @DataSagar

Nepal’s Infected Number Data Live extracted from open data platform by @DataSagar

Data Shows that Nepal is quite lucky in case of #CoronaDisaster though being nearer than the Countries like Japan, United States of America, Israel and France etc. from China.

Real time data of Japan seems like it’s indicating Nepal should get prepared for such unpredictable and unavoidable situation. IT’s high chance of virus spread as Nepal and India are Celebrating mass people gathering Festival of Colors – Holi in the next week. Image by illionSo may help you to understand this well.

So, my conclusion is, Better go for Precaution than painful Cure. Small and growing economies like Nepal mayn’t be able to handle epidemics like this disastrous flu. Answer in my conclusion should be a big NO unless it’s of optimal importance than your own precious life.

Regarding the Traveler’s safety, the World Health Organization (WHO) recommends following some safety tips for everyone to follow.

Dhanyawad and Stay safe everyone! I’ll be expecting some feedback and share from your end as I’m planning to post something new every week in this blog where I was inactive since long. @DataSagar

Structured Query Language: DDL, DML, TCL, DCL, DQL

SQL (Structured Query Language) is a programming language used to manage and manipulate data stored in relational databases. It is a standard language for interacting with relational databases and is used to create, read, update, and delete records in the database. It was the first commercial language introduced for E.F Codd’s Relational model. Today almost all RDBMS(MySql, Oracle, Informix, Sybase, MS Access) use SQL as the standard database language. SQL is used to perform all types of data operations in RDBMS.

SQL is a declarative language, which means that it specifies what the result should be, rather than how to get there. This makes it easy for users to understand and write SQL statements, even if they do not have a lot of programming experience. It is used in a wide range of applications, including web development, data analysis, and business management. It is a powerful and flexible language that is essential for working with relational databases.


SQL Types

There’re various types of SQL. Each type of SQL serves a specific purpose and is used in different situations. For example, DDL is used to define the structure of the database, while DQL is used to retrieve data from the database. There are several types of SQL, including:


1. DDL: Data Definition Language

DDL (Data Definition Language) is a type of SQL (Structured Query Language) that is used to define the database structure or schema. It is used to create, modify, and delete database objects such as tables, indices, and users. All DDL commands are auto committed which means DDL Commands save all the changes permanently in the database and rollback is difficult. Some examples of DDL statements include:

SQL CommandDescription
CREATE TABLEUsed to create a new table in the database or database itself
ALTER TABLEUsed to modify an existing table in the database
TRUNCATE TABLEUsed to clear all the values from the table
DROP TABLEUsed to delete a table from the database or the database itself
RENAMEUsed to rename a table
Fig: DDL Commands

2. DML: Data Manipulation Language

DML (Data Manipulation Language) is a type of SQL that is used to manage data within the database. It is used to insert, update, delete, and select data from the database. Unlike DDL, DML commands are not auto-committed. It means changes as a result of executing DML queries are not permanent to the database, they can be rolled back instantly. Following are some DML commands with their meanings:

CommandDescription
INSERT INTOUsed to insert new data into the database
UPDATEused to modify existing data in the database
DELETE FROMUsed to delete data from the database
MERGEUsed to merge two rows or two relations
Fig: DML Commands

3. TCL: Transaction Control Language

TCL (Transaction Control Language) is a type of SQL that is used to manage the transactions in the database. It is used to manage the changes made by DML statements. These commands are to keep a check on other DML commands and their effect on the database and to roll back to the original state. It can also make changes permanent in the database system.

CommandDescription
COMMITUsed to save the changes made by a transaction to the database i.e. to permanently save
ROLLBACKUsed to undo the changes made by a transaction
SAVEPOINTUsed to identify a point in a transaction to which you can later roll back i.e. to save temporarily

4. DCL: Data Control Language

DCL (Data Control Language) is a type of SQL that is used to control access to the database. It is used to grant and revoke permissions on the database objects to users. Data control language provides commands to grant and take the authority(access control rights) back. Some examples of DCL statements include:

CommandDescription
GRANTUsed to give a user permission to perform a specific task i.e. to grant permission for rights
REVOKEused to take back permission that was previously granted to a user

5. DQL: Data Query Language

DQL (Data Query Language) is a type of SQL that is used to retrieve data from the database. It is used to select, retrieve, and view data from the database. The SELECT statement is the most commonly used DQL statement.

CommandDescription
SELECTretrieve records from one or more table
