Hi Marcus Fetherston, welcome to our series "Behind the Startup." Please tell us about yourself and the story behind ? Ishan Pandey: Eightcap Eightcap is a multi-award-winning derivatives broker that has been operating since 2009. We were founded in Melbourne, Australia, and since then, we have rapidly expanded our services and products to reach traders worldwide. I'm currently the Head of Operation here at Eightcap so, I can tell you a lot more about our proposition and current offering. Our mission is to build a home for both MT4 and MT5 brokers and to do this. We provide a wide range of products with exceptional service. With Crypto derivatives trading trending now more than ever, we wanted to tap into this space and provide an outstanding offering for our clients. We now offer over 250 crypto derivatives, including coins, crypto crosses and crypto indices, all with ultra-low spreads. Marcus Fetherston: Please tell us about Crypto CFDs and how do they work? Further, please tell us about regulations regarding Crypto CFDs? Ishan Pandey: Trading Cryptocurrency derivatives has risk attached. Of course, this is the same as any leveraged products in the financial market. When you trade on leverage, both your profits and losses can be magnified. Crypto CFDs are no exception to this rule. Trading crypto CFDs allows you to take advantage of price fluctuations. At the moment, there is a lot of volatility in the market. This essentially means derivative traders can take advantage of both rising and falling prices making volatility an attractive aspect of trading crypto derivatives. With us, derivative traders can open positions in the crypto derivatives market via the MT4 and MT5 platforms. Marcu
s Fetherston: Crypto CFDs and Derivatives Should be Regulated for Investor's Safety. It's so easy for retail traders to fall victim to scams by questionable companies that aren't regulated. So, it is essential for any retail trader to only open accounts with brokers that are regulated by notable regulatory bodies. Eightcap is regulated in multiple jurisdictions. We are regulated by the Australian Securities and Investments Commission (ASIC), the Financial Conduct Authority (FCA), the Cyprus Securities and Exchange Commission (CySEC) and the Securities Commission of the Bahamas (SCB). As cryptocurrency trading has gained a lot of traction, especially in the past few years, regulation seems to have become a hurdle for retail traders. Derivative traders will need to see if their country of residence allows for them to trade cryptocurrency CFDs. We have stringent KYC measures in place when onboarding clients and make it very clear which countries we can accept retail traders from and which countries we don't. A lot of cryptocurrency CFDs platforms are operating without a license from the regulator where they are registered. What are your views on such unregulated cryptocurrency CFDs platforms and what are the risks attached with it? Ishan Pandey: We recommend that all derivative traders looking to open positions on the financial markets do their due diligence and research first. It's not easy if you are new to CFD trading, especially if you do not know who to open an account with. The CFD industry is swamped with brokers, so it is essential to choose one that meets your trading goals and can also count on for support. Marcus Fetherston: There are many risks associated with trading on an unregulated CFD platform. The biggest one is the risk of losing money. With a regulated broker such as Eightcap, retail traders are protected from fraud and ultimately have the peace of mind that they are with a broker that must comply with the rules laid out by their regulatory body. Please tell us about MT4 software and what are its advantages? Ishan Pandey: With the MT4 platform, traders can open positions on Forex, Indices, Commodities and Cryptocurrency CFDs. There are many advantages of using the MT4 platform and what makes us stand out with our MT4 offering is the customer support that goes hand in hand with our products. Our dedicated team of account managers and customer support agents are there on a 24/5 basis to help our clients at every stage of their trading journey. The MT4 platform itself is widely used and one of the most popular trading platforms. For example, our clients have access to over 400+ financial instruments via the MT4 and MT5 platforms. When trading with Eightcap's MT4 platform, clients will be able to trade CFDs with our raw account to experience spreads from 0.0pips. Alternatively, they can opt for our standard account and still experience low spreads with zero commission charged. Derivative traders can get started with an Eightcap MT4 account with as little as $100, with various funding methods such as BTC, Tether, PayPal, Bank Wire Transfer, Credit/Debit card and more. Marcus Fetherston: What advice would you give to traders on how to trade financial instruments? Ishan Pandey: Our primary mission is to build a home for both MT4 and MT5 traders. Therefore, preparing retail derivative traders for the financial market is integral to our service. My advice would be to really research the asset you want to trade and make sure you are trading with a broker that meets your needs. Education should be core to your trading strategy, from creating an effective trading plan to understanding more about technical analysis and how you can use that to make the most out of volatility. Every derivative trader should know these things, and a broker that provides free educational resources should be at the top of the list when trying to trade CFDs. Marcus Fetherston: With the platform clients have access to a vast library of educational articles that are updated frequently. They also receive regular market updates that cover all assets, especially crypto, and the trading week ahead, allowing traders to prepare for the key financial events and announcements that can affect the markets. Additionally, we also ensure we have events and webinars scheduled throughout the year so that our clients are consistently brushing up on their trading skills or getting expert insights from professional traders. What are your views on Web3 and how can it be leveraged in different industries? Ishan Pandey: The main advantage of Web3 is decentralisation, and this will benefit users in the long run when Web3 is leveraged in different ways and various industries. Right now, the idea is that Web3 is the next stage of the internet. We lived in a world of Web1, which only involved static HTML; we progressed onwards to Web2. Unfortunately, this has led to data breaches and is ultimately a centralised space. It's exciting to see how we can progress into the next era of the internet, especially with tokenisation as an incentive for users to develop and maintain their services in this space. Marcus Fetherston: How do you see the Web3 revolution impacting the development of dApps and the DeFi space? Ishan Pandey: If we look at an existing app, for example, Twitter, certain features that currently exist in Web2 could be revolutionised. At the moment, Twitter is a centralised app, and therefore, all tweets and accounts are inevitably censored. If we have Twitter as a dApp, we are looking at a version where everything is decentralised, so there won't be the same form of censorship as we see today. When we look at the way Web3 can revolutionise the DeFi space, well, for one, there won't be any need for personal data; therefore, payments won't be prevented or not allowed. Marcus Fetherston: Right now, in Web2, payment apps can decide not to process payments for different reasons. On the other hand, many different businesses have started to accept payments using crypto, so we are already moving towards a DeFi space. Eightcap accepts deposits in BTC and Tether and multiple other payment options to make the funding and withdrawal process seamless and easy for our clients. What role has the pandemic played in allowing traders to profit from cryptocurrency investments? Also, what do you think the post-covid-19 scenario would look like for the blockchain ecosystem? Ishan Pandey: I can't comment on how the pandemic has affected profit for traders. But due to the pandemic, there has been substantial amounts of volatility across several financial instruments. We have seen indices rise and plummet within the space of the month. For example, at the start of the pandemic, on February 19, 2020, the S&P 500 closed at an all-time-high (at the time). Marcus Fetherston: By March 2020, the index had dropped by more than a 51% decline. There has been an influx of new traders who have wanted to take advantage of price volatility. That's why we felt it vital to meet the demand for trading with educational resources and outstanding customer support. We wanted both new and experienced traders to make the most of market opportunities but have the correct tools and resources in place to do so. According to you, What new trends are we going to see in the blockchain industry? Ishan Pandey: The rise of NFTs is a big trend that could continue in 2022. We have already seen it taking hold of the music and art world. It will be interesting to see how other industries also use NFTs going into 2022. Many big-name brands want to get involved with NFTs, Nike to name one in particular, with their patent already placed on the virtual sneaker ‘CryptoKicks’ and I think this is a frenzy that is just starting. Marcus Fetherston: The ‘Metaverse’, a new digital world built around a fully functioning economy, comes up a lot when discussing trends in this space. Facebook has already announced this year that it would help bring the Metaverse to life, and if this is fulfilled, it could change everyday life as we know it. The Metaverse will be trending in 2022, especially as companies such as Decentraland have already started using cryptocurrency so that gamers can monetise their creations. We have included the Decentraland CFD and AXS CFD in our award-winning crypto offering to meet this trend. Our clients will be able to go long and short as the news around the Metaverse continues to progress. Whilst we see a further expansion into defi and further decentralization of more apps and technologies, the larger challenge in crypto will be building better bridging between the traditional finance world and the vast opportunities that defi and crypto present. As such I think we will see a greater transfer of institutional businesses continue moving into crypto to help facilitate bridging this gap between retail users and the world of crypto.

Importance and Tips of Financial Management in Small Business

refers to the intelligence demonstrated by computers. In today’s world, AI has become highly popular. It is the replication of human intelligence in computers that have been programmed to learn and replicate human activities. These computers can learn from their mistakes and do jobs like humans. AI will have a significant influence on our quality of life as it develops. And It’s only natural that everyone nowadays wants to engage with AI technology in some way. weather as a consumer or as a professional in the field. AI – Artificial Intelligence Introduction to Artificial Intelligence The quick answer is that it depends on who you ask. What is Artificial Intelligence? A person with only a basic grasp of technology might associate it with robots. AI, they believe, is a Robocop figure that can act and think for itself. If you ask an AI researcher what AI is. He or She will tell you that it is a set of that can create outcomes without being explicitly directed to do so. And they’d all be correct. algorithms To summarise, the meaning of AI is: An intelligent entity created by humans. Capable of performing tasks intelligently without being explicitly instructed. Capable of thinking and acting rationally and humanely. How do we measure if AI is acting like a human? Even if we get to the point where an AI can behave like a human. How can we be sure it will do so in the future? The following criteria can be used to assess an AI entity’s human likeness: Turing Test The Cognitive Modelling Approach The Law of Thought Approach The Rational Agent Approach How does AI Works? Building an AI system is a complex process of reverse engineering human traits and capabilities in a machine and then leveraging its computing strength to outperform our abilities. To understand fully how AI works. One must first dig into the many sub-domains of AI and understand how those domains maybe apply to various industries of the industry. ML teaches a computer how to make inferences and conclusions based on previous experience. It recognizes patterns, analyses previous data, and infers the meaning of these data points without relying on human experience to draw a decision. This automation of reaching conclusions by analyzing data saves firms time and allows them to make better decisions. Machine Learning (ML): DL is a machine learning approach. It trains a machine to categorize, infer, and predict outcomes by processing inputs through layers. : Deep Learning Human neural cells and Neural Networks both function on the same principles. They are a set of algorithms that capture the relationship between numerous underpinning variables. And analyze the information in the same way that a human brain does. Neural Networks: NLP is the science of a machine reading, understanding, and interpreting a language. When a computer understands what the user is trying to say, it reacts appropriately. Natural Language Processing (NLP): CV algorithms attempt to discover a picture by splitting it and analyzing various elements of the objects. This enhances the machine’s classification and learning from a group of photos, allowing it to make better output decisions based on prior observations. Computer Vision (CV): Cognitive computing algorithms attempt to emulate the human brain by analyzing text, voice, pictures, and objects. In the same way, as humans do, and then attempting to produce the appropriate output. Cognitive Computing: Where is AI Used? AI is being applied in a variety of fields to get insights into user behavior and provide data-driven suggestions. Google’s predictive search algorithm. For eg: Analyze user data from the past to forecast what a user would put next in the search field. previous user data to suggest what movie a user should watch next. Keeping them hooked on the site and increasing their viewing duration. Netflix leverages Facebook utilizes historical user data to automatically propose tags for your friends based on their facial traits in their photos. Large corporations employ AI to make the lives of their customers easier. AI’s applications are widely classified as data processing. Which includes the following: Searching within data, and optimizing the search to give the most relevant results. Logic-chains for if-then reasoning, that can be applied to execute a string of commands based on parameters. Pattern-detection to identify significant patterns in large data set for unique insights. Applied probabilistic models for predicting future outcomes. Advantages of Artificial Intelligence There’s no doubt that technological advancements have improved our lives. AI and other technologies have taken over everything from music suggestions to map directions, The line between development and destruction is fine. There are usually two sides to every coin, and AI is no exception. Take a look at some of the benefits of AI. mobile banking to fraud protection. AI devices or systems are less prone to mistakes and have higher accuracy. Since they make judgments based on prior knowledge or experience. High Accuracy with fewer errors: AI systems may be incredibly fast and make quick decisions, and as a result. They can beat a chess champion in a game of chess. High-Speed: AI robots are extremely dependable and can repeat actions with great precision several times. High reliability: In instances where employing a person would be unsafe. Such as defusing a bomb or researching the ocean below, AI computers can be useful. Useful for risky areas: AI may be highly beneficial in providing consumers with digital assistants. For eg: numerous E-commerce websites are presently using AI technology to offer items based on client requirements. Digital Assistant: AI may be highly valuable for public utilities such as self-driving cars. Which can make our journeys safer and more convenient. Face recognition for security, natural language processing, which allows us to speak with humans in our own language, and so on. Useful as a public utility: Disadvantages of Artificial Intelligence Every technology has drawbacks, and AI is no exception. Despite being such a , it still has several drawbacks that we must consider when developing an AI system. The following are some of AI’s drawbacks: beneficial technology AI’s hardware and software needs are quite expensive. As it requires a lot of maintenance to match current global requirements. High Cost: Even though AI is allowing us to create smarter machines. They cannot work out of the box since robots will only accomplish the task for which they have been trained or designed. Can’t think out of the box: AI machines can be excellent performers. But they lack emotion and hence cannot build emotional attachments with humans. They can also be dangerous to users if proper measures are not followed. No feelings and emotions: People are becoming more reliant on electronics as technology advances, and as a result, their mental capabilities are decreasing. Increase dependency on machines: Humans are very creative and can come up with new ideas. But AI computers will never be able to match this level of intellect or be as creative and imaginative as humans. No Original Creativity: Prerequisites for AI As a beginner, here are some essential requirements that will assist you in getting started with AI. A stronghold on . Mathematics such as Calculus, Statistics, and probability A good amount of experience in programming languages such as Java, or Python. A stronghold in understanding and writing algorithms. A strong background in data analytics skills. A good amount of knowledge in discrete mathematics. The will to learn . ML languages

What is Artificial Intelligence

is a live coding environment that runs on the browser. It is made by the team behind . The main objective here is to provide interactive examples to play around with, to users. I see it being widely used in things like blog posts and documentation (in fact the, work in progress, is using Sandpack). In this article, we are going to look at how to add Sandpack to a React Application and then we will look at integrating it with in a NextJS Application. Sandpack CodeSandbox new React Docs Next MDX Remote Adding Sandpack to our Project We are going to be adding Sandpack to a react application (made with ) though the process should be quite the same for NextJS or Gatsby. create react app Create a starter react project and navigate into it npx create-react-app sandpack-demo
cd sandpack-demo Note: Feel free to use the Yarn package manager if that is what you prefer. Now, let us install Sandpack npm install @codesandbox/sandpack-react That is it for dependencies, now let us move on to adding Sandpack to the application. Go ahead and delete , , , and . Also remove all the boilerplate code in . It should look like this - App.css App.test.js setupTests.js logo.svg App.js function App() {
  return <div></div>;
}

export default App; Now, let us import Sandpack in - App.js import { Sandpack } from "@codesandbox/sandpack-react";
import "@codesandbox/sandpack-react/dist/index.css"; Here, we are also importing a CSS file that contains the styles for the editor and preview. We should also add the Sandpack component - <Sandpack /> That is it!!! Now let us start the dev server by running . Navigate to and this is what you should see - npm start http://localhost:3000/ Custom Templates The default template that Sandpack uses is vanilla js but we can also use other templates like react, vue, angular, etc. Let us see the react template in action. Just add the attribute and specify the value as - template react <Sandpack template="react" /> Feel free to go through the for more templates and information on how to add your custom code. Sandpack Custom Content documentation Custom Theme We can also customize the theme. Let us look at adding a pre-built theme - <Sandpack template="react" theme="sandpack-dark" /> This is how the editor should look like - Feel free to go through the for more themes and information on building your theme. Sandpack Custom UI documentation At last, this is how our looks like - App.js import { Sandpack } from "@codesandbox/sandpack-react";
import "@codesandbox/sandpack-react/dist/index.css";

function App() {
  return (
    <div>
      <Sandpack template="react" theme="sandpack-dark" />
    </div>
  );
}

export default App; Now, that was just getting started with Sandpack but now let us look at it being used in a more real-world example. Feel free to go through the for more detailed guides and an API reference. Sandpack documentation Using Sandpack with Next MDX Remote is a library that parses MDX content (markdown but with support for JSX as well) and helps load them via or in NextJS. It is mainly used for documentation and blog posts. Today, we are going to be adding Next MDX Remote to a NextJS application and customize the code component by replacing it with Sandpack. First of all, let us make a new NextJS application and navigate into it - Next MDX Remote getStaticProps getServersideProps npx create-next-app sandpack-next-mdx-remote
cd sandpack-next-mdx-remote Now, let us delete under the directory and remove the boilerplate code in under the directory. This is how it should look like - Home.module.css styles index.js pages export default function Home() {
  return <div></div>;
} Adding Next MDX Remote The next step is to add and setup Next MDX Remote so let us do that - npm install next-mdx-remote Now, let us go to and add the following code - index.js import { serialize } from "next-mdx-remote/serialize";
import { MDXRemote } from "next-mdx-remote";

export default function Home({ source }) {
  return (
    <div>
      <MDXRemote {...source} />
    </div>
  );
}

export const getStaticProps = async () => {
  const source = "```html\n<h1>Hello World</h1>\n```";

  const mdxSource = await serialize(source);

  return { props: { source: mdxSource } };
}; Note that I am just writing down some basic markdown with a code block. Usually, this markdown is sourced from external files and paired with frontmatter but that is not something I am going to go over in this article. Now let us start the development server by running . Upon navigating to , this is what our page should look like - npm run dev http://localhost:3000/ Note that a simple HTML element is being rendered now code Now, I could add syntax highlighting to this using but as we are anyways going to use Sandpack, let us move onto that instead. remark prism Adding Sandpack to Next MDX Remote First of all, let us install the Sandpack package - npm install @codesandbox/sandpack-react Now let us create a directory called and add a file named in there. Add the following code to that file - components CustomMDXCode.js import { Sandpack } from "@codesandbox/sandpack-react";
import "@codesandbox/sandpack-react/dist/index.css";

const CustomMDXCode = props => {
  return (
    <Sandpack
      template={props.template}
      files={{ [`/${props.filename}`]: props.children }}
    />
  );
};

export default CustomMDXCode; Here, we are importing Sandpack, making a custom component, which is passed in some props. These props will contain the filename of the file, the template to use, and of course, the code. Note that we are adding a to the beginning of the filename through string interpolation as it is required by Sandpack. / Now, let us go back to our file and make some changes to leverage the use of the new component - index.js import { serialize } from "next-mdx-remote/serialize";
import { MDXRemote } from "next-mdx-remote";
import CustomMDXCode from "../components/CustomMDXCode";

export default function Home({ source }) {
  return (
    <div>
      <MDXRemote
        components={{ code: props => <CustomMDXCode {...props} /> }}
        {...source}
      />
    </div>
  );
}

export const getStaticProps = async () => {
  const source =
    "```js template=react filename=App.js\nexport default function App() {\n  return <h1>Just some text...</h1>\n}\n```";

  const mdxSource = await serialize(source);

  return { props: { source: mdxSource } };
}; Here, we are adding a custom component for the code attribute (reference for all mdx components - ), which is nothing but the Sandpack component we created earlier. We have also changed the markdown source to , added a attribute and pointed that to , added a attribute and named the file , and wrote a simple function that displays some text for the code part. https://mdxjs.com/table-of-components/ javascript template react filename App.js This is what our page should look like now: Conclusion That is it for this article. I hope you enjoyed it and learned how to add Sandpack to your react application. Feel free to comment on this post or reach out to me via in case you have any questions.

A while ago, I saw a meme video of "a day in the life of a software engineer" where the engineer wrote a script to make his computer switch on automatically, open Slack, and move the mouse at regular intervals while he is asleep to make it appear he is online and working at the same time. We will be writing a similar program with NodeJS using the . RobotJS is a cross-platform desktop automation library. RobotJS module This is for EDUCATIONAL purposes only. 😊 Steps Run to install required dependencies. npm install yargs robotjs create an file and paste the code below. (I will explain the code): app.js // app.js
const yargs = require("yargs");
const { hideBin } = require("yargs/helpers");

const arg = yargs(hideBin(process.argv))
  .command("$0 [interval]", true, (yargs) => {

  })
  .default("m", true)
  .help("h").argv; The code above configures the argument options our application needs and also defines a CLI interface to describe the application when you run . We will have options to run only keyboard press ( ), mouse move ( ) or both ( ) and define the time intervals of the events in seconds. node app.js -h -k -m -mk I wrote an article on parsing NodeJS CLI arguments here. We will define boolean variables to ascertain what operations to perform: let is_both;
let is_mouse;
let is_keyboard; Next, we will define functions to move the mouse and press the keyboard function moveMouseBackAndForth() {
	robot.moveMouseSmooth(200, 200);
  robot.moveMouseSmooth(400, 400);
}

function pressKeyBoard() {
  robot.keyTap("shift");
} Then we will call the functions depending on the arguments passed. The whole code will look like this: const yargs = require("yargs");
const robot = require("robotjs");
const { hideBin } = require("yargs/helpers");

let is_both;
let is_mouse;
let is_keyboard;

const arg = yargs(hideBin(process.argv))
  .command("$0 [interval]", true, (yargs) => {
    yargs
      .positional("interval", {
        type: "number",
        describe: "the interval in second",
      })
      .default("interval", 60); // 60 seconds default
  })
  .usage("runs a desktop automator to run key your  mmouse move at interval")
  .example(
    "$0 -mk 3",
    "moves the mouse and press the keyboard after three seconds"
  )
  .option("m", {
    description: "enable the mouse",
    type: "boolean",
  })
  .option("k", {
    description: "enable the keyboard",
    type: "boolean",
  })
  .default("m", true)
  .help("h").argv;

let { m, k, interval } = arg;
// multiply seconds by 1000 to get milliseconds
interval = interval * 1000;

if (m && k) is_both = true;
else {
  if (m) is_mouse = true;
  else if (k) is_keyboard = true;
}

function moveMouseBackAndForth() {
  robot.moveMouseSmooth(200, 200);
  robot.moveMouseSmooth(400, 400);
}

function pressKeyBoard() {
  robot.keyTap("shift");
}

if (is_both) {
  setInterval(() => {
    moveMouseBackAndForth();
    pressKeyBoard();
  }, interval);
} else if (is_keyboard) setInterval(pressKeyBoard, interval);
else {
  setInterval(moveMouseBackAndForth, interval);
} Run to move our mouse only at an interval of 3 seconds. node app.js -m 3 Thanks for reading through. Would you rather have the program do something else than press the keyboard?' You can get the code from this Github gist I appreciate your feedback and questions. First published here

How to Act Like You're Working When You're not With RobotJS

The banking industry is one of the many industries that have had a paradigm shift in the way it does its daily operations, thanks to modern technology. As we speak, online banking has become the new normal, and everyone wants to have control of his or her account from the comfort of his or her home. Although this has come with its advantages, it has introduced many bank accounts to many vulnerabilities, such as account hacking. After years of hard work and sacrifice, all your earnings can disappear overnight. Better still, all your business savings can be wiped off within a click of a button. This is the reason why you should optimize the security of your bank account. In this article, we shall take a closer look at how one can secure his or her bank account and other related ideas. Reasons Why Your Bank Account Was Hacked If your bank account has ever been hacked, here are some reasons that could have made you a victim of fraud. These include: 1. You utilized a WiFi service whose password was not protected. If you live in an urban area, chances are that you visit coffee shops to catch up with friends and family relatives. The good news is that most coffee shops have an internet connection that is free to use. If you use this internet to access your transfers, the chances of it being hacked are very high. After all, hackers like using unsecured networks as they are easy to access. Besides this, such networks provide them with several people to steal information from. bank account for online money 2. You are fond of using ATMs in sketchy locations Have you used card skimmers in the past? You will note that these devices are usually placed at ATMs or other locations where you are likely to swipe your credit or debit card to withdraw money or make payments. Hackers usually use this device to steal vital details about your bank account. In case you suspect that the card reader has a skimmer on it, try to jiggle the card reader to ensure that it is securely attached to the machine. Some of the common places where you will find these devices are gas stations, stand-alone ATMs, restaurants, and so forth. 3. You shopped at a retailer whose data was breached by hackers If your retailer of choice has had his or her data corrupted or breached, the chances of being a victim of such circumstances are very high. Such is usually the case whenever you do your shopping at that shopping outlet. Although you may not be an immediate victim of fraud, be sure that it will certainly occur to you. Therefore, you should stay up-to-date on the latest news to know the retail shops that might have had their data breached. 4. You opened an internet link through a text from an unknown number Hackers can also acquire your number online and then send you a fake text with a web link that claims to offer lucrative deals or bargains. Once you open the link, they will be able to access your information on the other hand and can use it to hack your bank account. 10 Best Ways to Secure Your Bank Account From Hackers Since we have established the various reasons why a hacker may have had access to your account, time is ripe for you to know how you can secure your bank account from fraud and other cybercrimes. 1. Always use a unique password for your bank accounts The importance of using strong passwords cannot be overemphasized. Ideally, you should set a strong password for your bank accounts. If you have multiple bank accounts, you should not set the same password for all of them. By doing so, you will make the bank accounts vulnerable to hacking. If a hacker gets to know one of your passwords, he or she can use it to access other accounts. Therefore, you should always ensure that your bank accounts have unique passwords that are hard to guess. 2. Enable a 2-factor authentication Besides using strong and unique passwords, you should enable a 2-factor authentication so that hackers can have a hard time accessing your bank account. Unlike other methods, this method works magic. Here, you will not only need a password, biometric login such as a facial scan or fingerprint to access your account but also a one-time code, which can always be sent to your phone so that you can type in. Even if the hacker knows your password, it will be difficult to assess your account as he will not have access to your mobile phone. 2. Avoid Wi-Fi networks that are not password protected If you are a frequent visitor to public places such as coffee shops and libraries, you should avoid using the Wi-Fi network present to access your bank accounts online. By doing so, you will expose yourself to a higher risk. If possible, try to access your bank account using a home network as hackers can hardly access it. 4. Invest in an encryption software As we speak, encryption software has become widely accessible and affordable. The good news is that this software usually encrypts both the activity and data on your computer. Consequently, it will be challenging for a hacker to access any of your vital details. 5. Get creative with security questions Once you forget your account’s password, chances are that you will be asked to answer several security questions. Hackers will undergo the same process once they try to access your account remotely. If a hacker reaches this stage, he or she should not have an easy time answering the security questions. Ideally, you should be creative with the answers you set for these questions. By doing so, you will be able to avert identity theft. For instance, if a security question asks, ‘where were you born?’ the answer should not be obvious. A good answer can be ‘onion’ or ‘grapes’. A hacker can hardly guess such an answer, and this will go a long way in securing your bank account. 6. Keep an eye on your bank statements Most banks usually send bank statements to members now and then. The moment you receive the bank statement, review it carefully. Once you notice that a certain transaction looks unusual, do not hesitate to contact your bank immediately. Chances are that someone might have had access to your bank account. In addition, if you get a push notification from your credit card company, you should not ignore them. In most cases, these companies usually send push notifications to your mobile device or tablet in case something looks fishy or suspicious during a purchase. For instance, if a large amount has been charged in a certain retail store, different from the retail stores that you are used to, you will get this notification on the go. Here, you will be asked to confirm whether you are the one who made the purchase or not. 7. Ensure that you update and patch your software every now and then Modern tech devices such as smartphones, tablets, and laptops need to get updated every now and then. By updating your device, you will be able to optimize the security of your device’s data. This is because hackers take advantage of the security loopholes in systems that are not up-to-date. Therefore, once you get that pesky software update notification, do not ignore it but rather consider it immediately. Apart from updating your device, ensure that you patch it regularly. Simply put, a patch is software that offers codes that seal all the security loopholes your device might have. You can get this software online from reliable sites and can help you keep your device’s data safe all the time. Consequently, you will be able to prevent bank account hacking by a large margin. 8. Install ad blockers Although some ads can be helpful, others are too good to be true. Even if you visited a genuine website, be careful before you click any ad you see on your screen. Nowadays, cybercriminals create ads that have malicious codes that can expose your bank account. In most cases, these ads offer free programs, among other goodies. Once you click them, malware will be downloaded to your device and can corrupt and steal vital information about yourself. Installing ad blockers can help keep these ads at bay. 9. Utilize the security features provided by your bank Different banks usually have different security features. To prevent your bank account from any form of fraud, you should take advantage of the existing security measures your bank has put in place. By doing so, you will keep sensitive information safe, and thus hackers will not be able to access your account. 10. Be careful of phishing scams Phishing is a common method that scammers use in order to gain access to someone’s bank account. Here, you will be prompted to give your personal financial information so that your data can be updated. Once you give your personal financial information, the scammer takes advantage of that and uses it to hack your bank account. In most cases, phishing scams come in the form of emails and links. Be careful whenever you receive an email that looks different from ordinary emails. Also, do not be quick to click any link that tells you to log in using your bank account details. Finally, if you receive a call from a person asking you about your banking information, be hesitant to shed more information. In most cases, a bank will contact you using their official number. Better still, the bank will inform you to visit the nearest branch so that you can update a few details, here and there. Final words The ordeal of having your bank account hacked is the last thing you ever wish to experience. If this happens, all your savings may go down the drain. In addition, you may have a difficult time accessing your account like you are used to. To avert all these inconveniences, you should consider the ideas we have mentioned above so that your account can remain safe. This will not only secure your bank account but also secure your money.

How To Secure Your Bank Account from Hackers

Here I will go over the alternative approach of designing huge applications. The end goal is to show how to substitute the monolithic architecture with micro frontends. I picked an admin dashboard as an example of an application that we will split into independent apps. But first, a quick overview of why micro frontends will be a great solution in such a case compared with monolithic architecture: Monolithic Admin dashboards usually contain a lot of components and complex logic. At some point, it becomes very difficult to maintain and scale the product. Besides that, it makes the integration of new developers quite challenging. Cause new joiners should spend a lot of time understanding and analyzing that huge monolith. Micro Front-ends This approach helps to split logic into smaller pieces. In that case, it's much easier to maintain and analyze the codebase. Moreover, responsibility for components can be delegated to different teams. So they can do independent development and deployment of these pieces. That makes micro front ends stand out. Demo App Architecture We need to create a workspace that will contain all the projects (components). The next step is the creation of a component wrapper, it is going to be responsible for the navigation of independent pieces and hosting them. The last part is to create micro frontends. That is all. Before we start, let me introduce the tool which is necessary to achieve the goal: Webpack 5 Module Federation Here is of it. Briefly, this is the main thing in my example. That plugin will allow loading front-end applications one into another. Let's proceed with implementation and see how it works. documentation Implementation As I mentioned above, in the beginning, we need to create the workspace, which is going to hold all projects. For that we need to run the following command: ng dashboard-mf --createApplication= new "false" After that, the host application has to be created, which is going to be a dashboard wrapper. ng g application dashboard --routing ng g c home --project=dashboard Also, we added a home component to the dashboard. Time to create the first micro front end: ng g application chart1 --routing Then it is needed to create a module inside that application that will be lazy-loaded to the host component, plus we can create a component that will display some demo content: ng g m bar --routing --project=chart1 ng g c bar --project=chart1 Setting up routing in the newly created application: dashboard-mf / projects / chart1 / src / app /app-routing.module.ts { NgModule } ; { RouterModule, Routes } ; routes: Routes = [
  { : , : ( ).then( m.BarModule)
  }
];

@NgModule({ : [RouterModule.forRoot(routes)], : [RouterModule]
}) { } import from '@angular/core' import from '@angular/router' const path 'chart1' loadChildren => () import './bar/bar.module' ( ) => m imports exports export class AppRoutingModule dashboard-mf / projects / chart1 / src / app / bar /bar-routing.module.ts { NgModule } ; { RouterModule, Routes } ; {BarComponent} ; routes: Routes = [
  { : , : BarComponent
  }
];

@NgModule({ : [RouterModule.forChild(routes)], : [RouterModule]
}) { } import from '@angular/core' import from '@angular/router' import from "./bar.component" const path '' component imports exports export class BarRoutingModule Then styling and some HTML content: dashboard-mf / projects / chart1 / src / app / bar /bar.component.html Statistics bar chart content < > section < > span </ > span </ > section { : ; : ; : ; : flex; : center; : center; : dashed ; : ; : ; : bold;
} section width 100% height 100% background-color #0088cc0f display justify-content align-items border 4px #73089f color #73089f font-size 50px font-weight We have almost everything ready to tie up the host app with the micro front end. At that point, the Module federation comes. That plugin should be installed for both parts: ng add @angular-architects/ -federation --project dashboard --port module 4200 ng add @angular-architects/ -federation --project chart1 --port module 5000 Important that both should be running in different ports. After installing a plugin, you can notice that inside the dashboard and chart1 components appeared a webpack configuration file ( ). To be able to run everything correctly we need to edit it a bit. webpack.config.js Inside the micro front end app, we need to uncomment code under "For remotes" comment and edit the code below. name: , : , : { : ,
        }, "chart1" filename "chartEntry.js" exposes './BarModule' './projects/chart1/src/app/bar/bar.module.ts' The same changes are applicable for the host app, but under the comment "For hosts". remotes: { : }, "chart1" "chart1@http://localhost:5000/chartEntry.js" Also, package.json should be updated. The following lines have to be added: : { : , : }, "resolutions" "webpack" "^5.4.0" "license-webpack-plugin" "2.3.17" Let's set up routing in the dashboard component to be able to load independent apps. Furthermore, we will add some content to HTML templates and style a bit a dashboard. dashboard-mf / projects / dashboard / src / app /app.component.html Home Statistics charts < > section < = > div class "sidenav" < = > a routerLink "/" < = > i class "fa fa-home" </ > i </ > a < = > a routerLink "/chart1" < = > i class "fa fa-signal" </ > i </ > a </ > div < = > div class "mf-content" < > router-outlet </ > router-outlet </ > div </ > section {NgModule} ; {RouterModule, Routes} ; {HomeComponent} ; routes: Routes = [
  {
    path: ,
    component: HomeComponent,
    pathMatch: },
  {
    path: ,
    loadChildren: ( ).then( { m.BarModule;
      })
  },
]; ({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
}) AppRoutingModule {
} import from '@angular/core' import from '@angular/router' import from "./home/home.component" const '' 'full' 'chart1' => () import 'chart1/BarModule' ( ) => m return @NgModule export class Here we will get an error, cause the dashboard app does not know anything about BarModule, so we need to declare it. For that, I created a file in the root of app where I declared a module. type.d.ts, dashboard-mf / projects / dashboard / src / app /app.component.scss @ url(//netdna.bootstrapcdn.com/font-awesome/ . /css/font-awesome.css); { : ; : ; : flex; : flex-end; : center; { : ; : ; : ;

  } { : ;
  }
} { : ; : ; : fixed; : ; : ; : ; : ; : hidden; : ;
} { : ; : none; : ; : ; : block; : ;
} :hover { : ;
} { : ; : ;
}

@ screen and (max-height: 450px) { { : ;} { : ;}
} import 4.0 3 section width 100% height 100% display justify-content align-items .mf-content width 83% height 95vh padding 15px i margin-right 10px .sidenav height 100% width 15% position z-index 1 top 0 left 0 background-color #0088cc overflow-x padding-top 20px .sidenav a padding 6px 8px 6px 16px text-decoration font-size 20px color #dddddd display margin-top 10px .sidenav a color #ffffff .main margin-left 160px padding 0px 10px media .sidenav padding-top 15px .sidenav a font-size 18px dashboard/src/app/home/home.component.html Home page content < > section < > span </ > span </ > section dashboard/src/app/home/home.component.scss { : ; : ; : ; : flex; : center; : center; : dashed orange; : orange; : ; : bold;

} section width 100% height 100% background-color #0088cc0f display justify-content align-items border 4px #73089f color #73089f font-size 50px font-weight To run the app, we need to serve dashboard and chrat1 projects. To do that, these commands have to be executed: ng serve dashboard serve chart1 ng Here is a quick overview of what we achieve so far. We have a home component that is part of the dashboard wrapper and also we have a link to "Statistics charts", once we click on them, the micro fronted "chart1" gets loaded: Wrapping up The goal is achieved, we have created an application that can host another independent app. This is just a simple introduction to how we can deal with micro frontends in Angular applications. This is a kind of template, which still requires a lot of things to be done. This is the first step of developing large applications using micro frontends. I left that example of the template in my , so feel free to pick it up. GitHub Hope it was useful! Cheers!

Splitting Angular Applications Into Micro Front-Ends

Introduction There are quite a few myths related to Single Page Application (SPA) and SEO, for example: SPA is bad for SEO. Use SPA if SEO is not important. Indexing requires prerendering which leaves SPA out in the cold. Indexing requires server-side rendering (SSR) which excludes client-side rendering (CSR) and therefore SPA that does CSR. Google generally understands SPA but crawling/rendering/indexing is a complex process. It makes indexing of any SPA difficult. Today’s reality is that both SPA and SEO can easily coexist and grow next to each other. The best way to dispel the surrounding myths is to present the evidence to the contrary: SPA Website Note Declared Sitemap Proof of Indexing crisp-react.winwiz1.com Demo website. Full-stack deployment. sitemap.xml Link Screenshot jamstack.winwiz1.com Demo website. Jamstack deployment. sitemap.xml Link Screenshot virusquery.com Production website. sitemap.xml Link Screenshot The Links in the table point to Google searches based on the keyword. Only indexed pages can appear in the search results, so if a page does show up then you know it has been indexed. However, not all indexed pages are guaranteed to be included. If a page doesn’t appear, you can perform a more specific search for the given page only, like . site: site: this The Screenshots shown in the table come from (GSC). It’s the primary tool to request and verify indexing. Google Search Console Some screenshots show the indexed pages as . It’s confusing since the pages are actually included in . This wording means Googlebot has initially discovered the pages without the sitemap and keeps crawling these without regards to the available . “Indexed, not submitted in sitemap” sitemap.xml sitemap.xml The rest of this article explains the steps aimed at getting a similar GSC screen for your SPA website. Groundwork Prerequisites Custom domain ownership. GitHub account. Cloudflare account. It's free and can be created by following this . link Installed software: Git. Deploy a SPA In this section we are going to deploy a React SPA to Cloudflare Pages using the following steps: Open a command prompt and clone Crisp React repository: git clone https://github.com/winwiz1/crisp-react.git cd crisp-react Create a new GitHub repository by visiting . repo.new Point the cloned repository to the newly created one and push it there: git remote set-url origin https://github.com/your-github-username/your-newly-created-repo git push Deploy to Cloudflare Pages by logging into the and creating a Cloudflare Pages project. Cloudflare dashboard This step will take several minutes spent mostly on waiting. It should take around a minute to copy the data provided below and paste it into the single configuration screen presented by Pages. Use . You will be asked to authorize read-only access to your GitHub repositories with an option to narrow the access to specific repositories. Select the repository which you pushed to GitHub at the previous step and on the "Set up builds and deployments" screen, provide the following information: Menu > Pages > Create a project Configuration option Value Production branch master Build command yarn build:jamstack Build output directory client/dist Add the following environment variable: Environment variable Value NODE_VERSION 16.13.1 Optionally, you can customize the "Project name" field. It defaults to the GitHub repository name and is used to create a 'per-project subdomain' e.g. . <project-name>.pages.dev After completing the configuration, click on the "Save and Deploy" button. When the deployment pipeline finishes, the website will be partially functional. Point a browser to to check the site is online. https://<project-name>.pages.dev/first Let Cloudflare manage DNS for the domain you own and want to use for the deployment. You don’t have to change your domain registrar to Cloudflare though you could if you want to. If you do or if you purchase a brand new domain through Cloudflare, skip this step. Use the top-level menu available in the Cloudflare dashboard. In response, Cloudflare will provide you with the names of two DNS nameservers. Login to the domain registrar account and change the nameservers from the ones supplied by the registrar to the nameservers provided by Cloudflare. Add a site In the Cloudflare dashboard, use the DNS menu to add a record: Type Name IPv6 Address AAAA subdomain 100:: Replace with either a subdomain name e.g. to deploy to or apex e.g. if you prefer to use the root domain.  Check the "Proxy status" of the record is set to "Proxied". subdomain jamstack jamstack.<your-domain>.com @ The "Proxied" status ensures the DNS record won't become public. Cloudflare will create another public DNS record that ensures the requests for are routed to Cloudflare datacenters. Once handled there, the requests would have been dropped since the address is used to discard traffic. But in reality, the requests will be handled by the Worker we are about to create at the next step. subdomain 100:: Create a Cloudflare Worker by visiting and replace the auto-generated code with the content of file. Modify the Worker Customisation block at the top of the code by following the suggestions in the comments. Modifying the code includes two steps: workers.new this Edit the variable and replace all the occurrences with . siteMap jamstack.winwiz1.com <subdomain>.<your-domain>.com Edit the variable and replace the single occurrence of with the per-project subdomain e.g. . pagesDomain https://crisp-react.pages.dev https://<project-name>.pages.dev Click on the “Save and Deploy” button. This step along with the next one will be automated in the future. The default Workers Plan is free but has a limitation: 100,000 invocations per day. Unmap the Worker from the domain it was automatically deployed to. Map it to your custom domain or subdomain instead to ensure the Worker is invoked to handle each request. For example, the Worker for should be mapped to the path . *.workers.dev <subdomain>.<your-domain>.com <subdomain>.<your-domain>.com/* Point a browser to and verify the website is online and functional. https://<subdomain>.<your-domain>.com Request Indexing In this section, we’ll ask Google to: Confirm that each SPA page can be indexed, Accept a request to index each SPA page. Both confirmation and acceptance will be obtained by using which is a part of GSC. Google URL Inspection Tool Perform the following steps: Add some original content to the deployed website in order to avoid . duplicate content In the SPA , set the variable to a different title. Review the SPA codebase to ensure each page correctly sets the HTML element and the canonical tag to the values meaningful for the page. This can be done by searching all files for the pattern and reviewing the relevant code. Configuration block appTitle <title> <meta> .tsx <Helmet> If you have changed not only the content of a webpage but also its path or added new pages, then you will need to modify the Worker Customisation block to reflect the changes. Commit the code changes made at the previous two steps and push the commit to your GitHub repository. The push will trigger an automated build and deployment of the website by Cloudflare Pages. the domain you own to GSC using the “+ Add Property” menu. Add For example, the production was added as a domain property whereas for the demo websites the root domain was added first as a domain property . Once Google has verified the domain ownership, both demo websites were added separately as a URL property each e.g. and . website virusquery.com winwiz1.com https://crisp-react.winwiz1.com/ https://jamstack.winwiz1.com/ Click on the “URL Inspection” menu to activate the and type the path to the page you would like to index: URL Inspection Tool You can copy the path from and paste it. On contrary to the screenshot above the response will state that “URL is not on Google” telling you the page hasn’t been indexed yet. sitemap.xml Click on the button to get a confirmation the page can be indexed. Optionally review the screenshot of the page rendered by GSC. "TEST LIVE URL" Request indexing for the page by clicking on the link. The response should say your request has been added to the priority crawl queue. "REQUEST INDEXING" The last 3 steps will have to be repeated for all the pages of each SPA. Follow-up You can use the “URL Inspection” menu to monitor if the page was indexed. It can take from a few days to a couple of weeks for the page to be added to Google index. At which time the response will state: “URL is on Google”. When that happens, you can double-check that the page was indexed by performing Google search using the keyword. site: Finally, it will take up to another week for the indexed pages to appear in the indexing report under the GSC “Coverage” menu. Under the Hood Let’s dissect what the Cloudflare Worker does and find out when & why is it needed. Plain SPA Google has no trouble with rendering a SPA presented by a typical HTML file that has a nearly empty element with references to scripts only. This HTML markup makes sense for CSR since the HTML and the DOM are generated at run time in the browser’s memory. You can observe such a markup on the demo websites mentioned at the beginning of the article, just jump to the second SPA and right-click on the page to ‘View page source’. <body> The page that belongs to the second SPA is indexed. It suggests the concern about the alleged fundamental troubles that Google has with an ‘empty’ SPA page has no merit. The only difference is the extra ‘Rendering’ stage in the indexing pipeline. Also when you click on the link in GSC to inspect that particular page, the screenshot of the page appears on the right pane. It proves the scripts were duly run resulting in proper rendering of the ‘empty’ page. "TEST LIVE URL" Selectively Prerendered SPA Now let’s switch from a plain SPA to the one with the landing page prerendered. Crisp React builds such SPA to combine landing page prerendering with CSR for other pages. This is done to achieve performance. Once the landing page is prerendered, the SEO troubles start. The indexing pipeline sees the HTML markup generated by prerendering and decides that it can optimise the scripts out. It assumes there is no need to run any client-side scripts because the markup, and therefore the page content, is already there. No client scripts execution amounts to having no CSR and no SPA page switching. As a result, GSC reports under the “Coverage” menu that all the non-landing pages are treated as duplicates of the landing page and not indexed. Despite of all the pages having different content. The remedy was simple. After in Cloudflare Worker was used to strip out the prerendered HTML markup, all internal (e.g. non-landing) SPA pages were indexed. HTMLRewriter An attentive reader can ask if this amounts to website cloaking. The answer is No. Google provides definitions for ‘hybrid rendering’ and ‘dynamic rendering’. Both result in Googlebot and users receiving different content which effectively is a cloaking, albeit permitted by Google. In our case the rendering stage of Google indexing pipeline sees what is rendered by the script whereas users are presented with the output of React function which yields the same HTML markup and page content. renderToString Cloudflare Worker Functionality The Worker is used to implement the following features: Feature: Conditionally remove prerendering for bots but not for end-users. In Crisp React the prerendering is optional so if no SPA has it enabled then obviously no need to remove it. Alternative: If you need prerendering but are not using edge functions like Workers, then switch from Jamstack to full-stack deployment and implement prerendering removal in the backend e.g. Express. The implementation is as simple as finding the element and removing its children. div.app-root Feature: Implement SPA redirects. This is done as a workaround for Cloudflare Pages assumption that any SPA has the landing/index  page called . This is not necessarily true for Crisp React, it allows a React application to be split into multiple SPAs and you can name each as you like. index.html Alternative: Use one SPA only and rename it from ‘first’ to ‘index’ to let Pages perform redirects. Or switch to full-stack deployment and implement redirects in the backend. Feature: Generate auxiliary files e.g. , . sitemap.xml robots.txt The files are created on the fly and are not persisted to the disk. Alternative: The files could be created on the disk during build time or generated on the fly by the backend in full-stack deployments. Conclusion Hopefully, this article sheds some light on the SPA & SEO topic. As you could see, the overall picture is quite bright and certainly not as bleak as frequently painted. Getting your website indexed is only the first, though critical, stretch of the long SEO road. It’s highly recommended to ensure your SPA includes meaningful Structured Data.

In this post, our gaming community discusses their favourite Telltale games. We cover our favourite Telltale games alongside the ones we want next. slogging This Slogging thread by Jack Boreham, Limarc Ambalina, Mónica Freitas, Sara Pinto, Adrian Morales and Jose Hernandez occurred in slogging's official #gaming channel and has been edited for readability. Jack Boreham Nov 30, 2021, 1:26 PM What are the best Telltale games? Limarc Ambalina Nov 30, 2021, 2:30 PM A question close to my heart. So my favorite still is Walking Dead Season 1. Nothing beats that yet IMO. IT exists alongside the real walking dead timeline and is complementary to it. You even get to see a character or 2 from the tv series in the game. And everything was done masterfully: the story, the choices you get to make, the soundtrack, THE SOUNDTRACK, the art style, the atmosphere. Everything was done so well. Mónica Freitas Nov 30, 2021, 2:47 PM Jack Boreham It appears to be "Tales From The Borderlands." I found a fun article about telltales games you should play before they disappear. Have you ever played any of them? https://www.pastemagazine.com/games/telltale/telltale-games-ranked/#1-telltale-s-the-walking-dead Limarc Ambalina Nov 30, 2021, 4:24 PM For me, #2 would be a toss-up between Game of Thrones or Wolf Among Us. It is so good. I hope the new telltale game finishes it because it's really good. You feel like you are making decisions in the world of GoT!!! Limarc Ambalina Nov 30, 2021, 4:26 PM Wolf Among us is so unique, and the world is so cool: the fairytale creatures and characters we all know and love: cinderella, sleeping beauty, the big bad wolf, and more, are all taken from their fairytale worlds and now live in a Gotham-like city and have to live among normal people. They resort to crime, prostitution even. It's such a unique story and setting. I recommend it for anyone who likes visual novels or adventure games. Jack Boreham Dec 1, 2021, 7:14 AM Limarc Ambalina, all great games. Surprisingly I've never actually played a telltale game. What do you like so much about them? The art style? The live sequence driven narrative? I've seen walkthroughs of the walking dead one, and I loved the look of it. Jack Boreham Dec 1, 2021, 7:16 AM Mónica Freitas never 😂, but I think these could be games for you. I've heard all of these games have great stories. Are there any that catch your eye? Limarc Ambalina, I remember watching the walking dead game on Youtube and being fearful for what might come next, for I think her name was Clementine? She seemed like a relatable character just trying to make her way in a zombie-infested world. Limarc Ambalina Dec 1, 2021, 8:01 AM Hey Jack, for me, it's mostly the story. I play games mostly to experience great stories, and these games are all stories. The gameplay is to help you get more immersed in them, but the stories are strong enough on their own, in my opinion. I love the art style and the music and voice acting are just superb. Telltale deserves more love than it gets. Limarc Ambalina Dec 1, 2021, 8:01 AM I would even say the Walking Dead Telltale game had a better story than the tv show did Mónica Freitas Dec 1, 2021, 12:37 PM Jack Boreham, I'd try the "Strong Bad’s Cool Game for Attractive People." Getting points for verbal abuse seems quite enjoyable when I'm in a bad mood 😂 Sara Pinto Dec 1, 2021, 4:25 PM Jack Boreham I don't think I've ever played Telltale games as well, but I think I would enjoy them.  I like the concept of being divided into episodes. Which one do you think you would like to try? The Game of Thrones one seems interesting! Jack Boreham Dec 2, 2021, 10:23 AM Limarc Ambalina, that's a hot take. I think many people would agree with you. It's a shame the zombie market is so damn saturated; I think it could do with another series. Did it end well, or was it anti-climatic? Mónica Freitas sounds like my kind of game as well😂. Sara Pinto, I think I would try the Batman games. I love Batman, so that it would be right up my alley. 🔥 2 Jack Boreham Dec 3, 2021, 11:10 AM Blake Cram  Nicolas Ng Allyson Blinkhorn Jose Hernandez? 😄 Adrian Morales Dec 3, 2021, 5:18 PM I have only ever played one TellTale game before, and it was The Walking Dead Season 1, which Limarc Ambalina already mentioned. But I will reiterate that it is a masterpiece. I have come back to it frequently throughout the years, and no game tugs on my heartstrings as much as that one. Jose Hernandez Dec 5, 2021, 1:15 AM For me, it would have to be the Batman telltale game. It puts more focus on the character’s detective skills and lets people play as Bruce Wayne. Which sounds kind of boring, but it's pretty interesting. Limarc Ambalina Dec 6, 2021, 5:18 AM Nice Jose Hernandez, I completely forgot about that one. I’m playing it right now and can agree. It immerses you in Gotham in a special way. Jack Boreham Dec 6, 2021, 11:01 AM Jose Hernandez, I agree!! Adrian Morales Dec 7, 2021, 3:43 PM There are so many great X-Men characters and a ton of untapped potential to make compelling TellTale style stories within the X-Men universe. Jack Boreham Dec 8, 2021, 6:06 PM X-men would be incredible. An avengers one would be good too!

What are the Best Telltale Games?

I love cooking and use my a lot. If you hadn’t heard about that amazing innovation, it's a kitchen robot… Well, it’s a magical super cooking machine. When designing the Thermomix, its designers took the approach of instead of . This is a smart choice in this case, but it has its drawbacks. Thermomix fail-safe fail-fast E.g. my machine tried to recover from a failure which sent it into an infinite recovery loop. I literally couldn’t pull out the food from the lid that was sealed shut. But normally, it’s one of the most reliable devices I own. Which approach should we take when we are developing our tools and how does that impact our long-term reliability? Fail-Fast vs. Fail-Safe Approach In case you aren’t familiar with the terms, fail-fast means a system that would quickly fail in an unexpected condition. A fail-safe system will try to recover and proceed even with bad input. Java tries to take the fail-fast approach, whereas JavaScript leans a bit more towards the fail-safe approach. A good example of fail-fast behavior would be their respective approaches to null. In Java, a null produces a NullPointerException which fails the code instantly and clearly. JavaScript uses “undefined” which can propagate through the system. Which one Should we Pick? This is hard to tell. There's very little research and I can't think of a way to apply the scientific method objectively to measure this sort of methodology. It has both technical aspects and core business aspects. It's pretty hard to determine something conclusively. What I can say for sure is that this shouldn't be a senior executive decision alone. This is a sort of policy that management should integrate with engineering to mitigate the downside risk. This applies to you, whether you're an engineer or a business leader. Whether you're a Silicon Valley startup, Amazon or a bank. These principles are universal. Companies using Microservices are probably more committed to some form of fail-safe. Resiliency is a common trait of Microservices, that’s in the fail-safe camp. Modern approaches to fail-safe try to avoid some pitfalls of the approach by using thresholds to limit failure. A good example of this is a circuit breaker, both the physical one and software-based. A circuit breaker disconnects functionality that fails so it doesn’t produce a cascading failure. Companies that pick the fail-fast approach take some risks but reap some big rewards. When you pick that approach, the failure can be painful if a bug reaches production, but there are two significant advantages: It's easier to catch bugs in fail-fast systems during the development/debugging cycle These bugs are usually easier to fix The fail-fast approach handles such bugs better since there's a lower risk of cascading effect. A fail-safe environment can try to recover from an error and postpone it. As a result, the developer will see an error at a much later stage and might miss the root cause of the error. Historically, ; I believe it makes systems more stable when we reach production. But this is anecdotal and very hard to prove empirically. I think a fail-fast system requires some appetite for risk, both from engineering and from the executives. Maybe even more so from the executives. I prefer fail-fast Notice that despite that opinion I said that the Thermomix was smart to pick fail-safe. Thermomix is hardware running in an unknown and volatile environment. This means a fix in production would be nearly impossible and very expensive to deploy. Systems like that must survive the worst scenarios. We need to learn from the previous failures. Successful companies use both approaches, so it's very hard to pick the best approach. Hybrid Environment in the Cloud A more common "strategy" for handling failure is to combine the best aspects of both worlds: Fail-fast when invoking local code or services, e.g. DB Fail-safe when depending on remote resources, e.g. remote web service The core assumption behind this direction is that we can control our local environment and test it well. Businesses can't rely on a random service in the cloud. They can build fault-tolerant systems by avoiding external risks but taking the calculated risks of a fail-fast system. Defining Failure When discussing failure the assumptions we make focus around a 500 error page, crash, etc. Those are serious P1 failures. But by no means are they the only type of failures or even the worst types of failure... A crash usually marks a problem we can fix and even workaround by spinning up a new server instance automatically. This is actually a failure we can handle relatively elegantly. A far more sinister failure is data corruption. A bug can cause bad data to make its way into the database and potentially cause long-term problems. Even security risks and crashes can result from corrupted data and those will be much harder to fix. A fail-fast system can sometimes nip such issues in the bud. With cloud computing, we're seeing a rise in defensive programming such as circuit breakers, retries, etc. This is unavoidable, as the assumption behind this is that everything in the cloud can fail. We need to develop core knowledge on the failures we can expect. One approach I found useful is to review logs from long-running integration tests (nightly tests). An important part of a good QA process is long-running tests that take hours to run and stress the system. When reviewing the logs of these tests, we can sometimes notice issues that didn't fail but conflict with our assumptions about the system. This can help find the insidious bugs that went through. Don't Fix the Bug Not right away. Well, unless it's in production, obviously... We should understand bugs before we fix them. Why didn't the testing process find it? Is it a cascading effect or is it missing test coverage? How did we miss that? When developers resolve a bug, they should be able to answer that question on the issue tracker. Then comes the hard problem, find the root cause of the failure and fix the process so such issues won't happen again. This is obviously an extreme approach to take on every bug, so we need to apply some discretion when we pick the bugs to focus on. But this must always apply to a bug in production. We must investigate bugs in production thoroughly since failure in the cloud can be very problematic to the business, especially when experiencing exponential growth. Debugging Failure Now that we have a general sense of the subject, let’s get into the more practical aspects of a blog focused on debugging. There's no special innovation here. Debugging a fail-fast system is pretty darn easy. But there are some gotchas, tips, and tricks we can use to promote fail-fast. There are other strategies we can use to debug a fail-safe system. Ensuring we Fail-Fast Use the following strategies: Throw exceptions - define the contract of every API in the documentation and fail immediately if the API is invoked with out of bounds state, values, etc. Enforce this strategy with unit tests - go over every statement made in the documentation for every API. Write a test that enforces that behavior If you rely on external sources, create tests for unavailable situations, low performance, and sudden unavailability Define low timeouts, never retry The core idea is to fail quickly. Say we need to invoke an Amazon web service. A networking issue can trigger a failure. A fail-fast system will expect a failure and present an error to the user. Intelligent Failure for Fail-Safe The core idea isn't so much to avoid failure, it's unavoidable. The core idea is to soften the blow of a failure. E.g. if we take the Amazon web service example from above... A fail-safe environment could cache responses from Amazon and would try to show an older response. The problem here is that users might get out-of-date information and this might cause a cascading effect. It might mean it will take us longer to find the problem and fix it since the system might seem in order. The obvious tip here is to log and alert on every failure and mitigation so we can address them. But there's another hybrid approach that isn't as common but might be interesting to some. Hybrid Fail-Safe A hybrid fail-safe environment starts as a fail-fast environment. This is also true for the testing environment and staging. The core innovation is wrappers that enclose individual components and provide a failsafe layer. This can be very similar to CloudFlare or Amazon cloud front providing a cached version of the website. But how can we apply this in the code or the OPS layer? When the system is nearing production, we need to review the fault points within the system, focusing on external dependencies but also on internal components. A simplistic example like the Amazon example from above will include a quick failure by default. The failsafe wrapper can retry the operation and can implement various policies. There's some ready-made software tools that let us define failsafe strategy after the fact, e.g. failsafe, spring-retry and many other such tools. Some of these tools are at the SaaS API levels and can mitigate availability/networking issues. This has the downside of adding a production component that's mostly missing in development and QA. But it includes many of the advantages of fail-fast and keeps the code relatively clean. Additional Best Practices for all Here are some best practices you should keep in mind, regardless of the strategy you pick: Run the software in the debugger with exception breakpoints turned on. Exclude APIs that use exceptions to control flow (ugh, please fix those APIs) from the breakpoint. This lets you challenge your assumptions about the reliability of the application Make sure the environment is random. If you use native code, randomize memory locations. Always randomize test execution to promote failure Proper code review - I can't stress this enough. I love code reviews. I despise nitpicking!
When I get a response on variable naming, code styling etc. it pushes my buttons... Sometimes comments like that ignore an actual bug.
People hate code review because of that type of nitpicking. Companies should train developers in substantive processes and evaluation. TL;DR Failure can come in many shapes and forms. We should accept that failure happens. It happens to Amazon, Facebook and Google despite all their efforts to avoid it. We need to decide on a strategy. Make assumptions and get support from senior management all the way through engineering. We need to make choices: Do we fail more often and recover quickly? Do we fail rarely but take time to recover? Software reliability is still a function of QA/testing. But ultimately, failure is inevitable and we need to make strategic choices. I believe most startups should focus on fail-fast, since the growth mindset makes it very hard to keep fail-safe strategies functional. Since we have QA and testing, most of these issues are outliers and they are very hard to optimize for.

Fail-Fast vs. Fail-Safe: What is the Most Reliable Software Strategy?

This is a self-contained demo using . Materialize This demo would show you how to use Materialize to join MySQL and Postgres in a live materialized view. For this demo, we are going to monitor the orders on our demo website and generate events that could, later on, be used to send notifications when a cart has been abandoned for a long time. Prerequisites Before you get started, you need to make sure that you have Docker and Docker Compose installed. You can follow the steps here on how to install Docker: Installing Docker Overview As shown in the diagram above we will have the following components: A mock service to continually generate orders. The orders would be stored in a MySQL database. As the database writes occur, Debezium streams the changes out of MySQL to a Redpanda topic. We also would have a Postgres database where we would get our users from. We would then ingest this Redpanda topic into Materialize directly along with the users from the Postgres database. In Materialize we will join our orders and users together, do some filtering and create a materialized view that shows the abandoned cart information. We will then create a sink to send the abandoned cart data out to a new Redpanda topic. You could, later on, use the information from that new topic to send out notifications to your users and remind them that they have an abandoned cart. As a side note here, you would be perfectly fine using Kafka instead of Redpanda. I just like the simplicity that Redpanda brings to the table, as you can run a single Redpanda instance instead of all of the Kafka components. Running the demo First, start by cloning the repository: git clone https://github.com/bobbyiliev/materialize-tutorials.git After that you can access the directory: cd materialize-tutorials/mz-join-mysql-and-postgresql Let's start by first running the Redpanda container: docker-compose up -d redpanda Build the images: docker-compose build Finally, start all of the services: docker-compose up -d In order to Launch the Materialize CLI, you can run the following command: docker-compose run mzcli This is just a shortcut to a docker container with pre-installed, if you already have you could run instead. postgres-client psql psql -U materialize -h localhost -p 6875 materialize Create a Materialize Kafka Source Now that you're in the Materialize CLI, let's define the tables in the database as Redpanda sources: orders mysql.shop CREATE SOURCE orders
FROM KAFKA BROKER 'redpanda:9092' TOPIC 'mysql.shop.orders'
FORMAT AVRO USING CONFLUENT SCHEMA REGISTRY 'http://redpanda:8081'
ENVELOPE DEBEZIUM; If you were to check the available columns from the source by running the following statement: orders SHOW COLUMNS FROM orders; You would be able to see that, as Materialize is pulling the message schema data from the Redpanda registry, it knows the column types to use for each attribute: name      | nullable |   type
--------------+----------+-----------
 id           | f        | bigint
 user_id      | t        | bigint
 order_status | t        | integer
 price        | t        | numeric
 created_at   | f        | text
 updated_at   | t        | timestamp Create materialized views Next, we will create our first Materialized View, to get all of the data from the Redpanda source: orders CREATE MATERIALIZED VIEW orders_view AS
SELECT * FROM orders; CREATE MATERIALIZED VIEW abandoned_orders AS
    SELECT
        user_id,
        order_status,
        SUM(price) as revenue,
        COUNT(id) AS total
    FROM orders_view
    WHERE order_status=0
    GROUP BY 1,2; You can now use to see the results: SELECT * FROM abandoned_orders; SELECT * FROM abandoned_orders; For more information on creating materialized views, check out the section of the Materialize documentation. Materialized Views Create Postgres source There are two ways to create a Postgres source in Materialize: Using Debezium just like we did with the MySQL source. Using the Postgres Materialize Source, which allows you to connect Materialize direct to Postgres so you don't have to use Debezium. For this demo, we will use the Postgres Materialize Source just as a demonstration on how to use it, but feel free to use Debezium instead. To create a Postgres Materialize Source run the following statement: CREATE MATERIALIZED SOURCE "mz_source" FROM POSTGRES
CONNECTION 'user=postgres port=5432 host=postgres dbname=postgres password=postgres'
PUBLICATION 'mz_source'; A quick rundown of the above statement: : Materializes the PostgreSQL source’s data. All of the data is retained in memory and makes sources directly selectable. MATERIALIZED : The name for the PostgreSQL source. mz_source : The PostgreSQL connection parameters. CONNECTION : The PostgreSQL publication, containing the tables to be streamed to Materialize. PUBLICATION Once we've created the PostgreSQL source, in order to be able to query the PostgreSQL tables, we would need to create views that represent the upstream publication’s original tables. In our case, we only have one table called so the statement that we would need to run is: users CREATE VIEWS FROM SOURCE mz_source (users); To see the available views execute the following statement: SHOW FULL VIEWS; Once that is done, you can query the new views directly: SELECT * FROM users; Next, let's go ahead and create a few more views. Create Kafka Sink let you send data from Materialize to an external source. For this Demo, we will be using . Sinks Redpanda Redpanda is a Kafka API-compatible and Materialize can process data from it just as it would process data from a Kafka source. Let's create a materialized view, that will hold all of the high volume unpaid orders: CREATE MATERIALIZED VIEW high_value_orders AS
      SELECT
        users.id,
        users.email,
        abandoned_orders.revenue,
        abandoned_orders.total
      FROM users
      JOIN abandoned_orders ON abandoned_orders.user_id = users.id
      GROUP BY 1,2,3,4
      HAVING revenue > 2000; As you can see, here we are actually joining the view which is ingesting the data directly from our Postgres source, and the view which is ingesting the data from the Redpanda topic, together. users abandond_orders Let's create a Sink where we will send the data of the above materialized view: CREATE SINK high_value_orders_sink
    FROM high_value_orders
    INTO KAFKA BROKER 'redpanda:9092' TOPIC 'high-value-orders-sink'
    FORMAT AVRO USING
    CONFLUENT SCHEMA REGISTRY 'http://redpanda:8081'; Now if you were to connect to the Redpanda container and use the command, you will be able to read the records from the topic. rpk topic consume However, as of the time being, we won’t be able to preview the results with because it’s AVRO formatted. Redpanda would most likely implement this in the future, but for the moment, we can actually stream the topic back into Materialize to confirm the format. rpk First, get the name of the topic that has been automatically generated: SELECT topic FROM mz_kafka_sinks; Output: topic
-----------------------------------------------------------------
 high-volume-orders-sink-u12-1637586945-13670686352905873426 For more information on how the topic names are generated check out the documentation . here Then create a new Materialized Source from this Redpanda topic: CREATE MATERIALIZED SOURCE high_volume_orders_test
FROM KAFKA BROKER 'redpanda:9092' TOPIC ' high-volume-orders-sink-u12-1637586945-13670686352905873426'
FORMAT AVRO USING CONFLUENT SCHEMA REGISTRY 'http://redpanda:8081'; Make sure to change the topic name accordingly! Finally, query this new materialized view: SELECT * FROM high_volume_orders_test LIMIT 2; Now that you have the data in the topic, you can have other services connect to it and consume it and then trigger emails or alerts for example. Metabase In order to access the instance visit if you are running the demo locally or if you are running the demo on a server. Then follow the steps to complete the Metabase setup. Metabase http://localhost:3030 http://your_server_ip:3030 Make sure to select Materialize as the source of the data. Once ready you will be able to visualize your data just as you would with a standard PostgreSQL database. Stopping the Demo To stop all of the services run the following command: docker-compose down Conclusion As you can see, this is a very simple example of how to use Materialize. You can use Materialize to ingest data from a variety of sources and then stream it to a variety of destinations. In the second part of this demo, we will build upon the current demo and add more functionality to make represent a more realistic eCommerce website and a more realistic data pipeline.

Take your Materialized Views to the Next Level by Joining MySQL and Postgres

In decentralization, we trust, and in our community, we believe! This interview is part of the ! For those who are reading about it for the first time, HackerNoon has built a partnership with Everscale (Formely Free Ton) - a decentralized, community-powered blockchain movement for free Internet! This is the last month to participate in the contest. You can see all here. #Decentralized-Internet writing contest #Decentralized-Internet stories So without further ado, let’s start the interview. Thank you for joining us! Please tell us about yourself. I am Renjit Philip. I invest in and advise startups in the Middle East, the US, and India. I also am a Blockchain education evangelist for , a company based in Dubai, working to bring high-quality live blockchain programming training to learners. futureu.co Let's discuss centralized Internet first. What is your opinion on the centralized Internet? What are its pros/cons? The centralized Internet has brought value to the world and has created jobs and value for investors. It has also resulted in a few companies such as Google, Facebook that have cornered a disproportionate share of the control and value extracted from the centralized Internet. By design, the Centralized Internet needs to rely on advertising revenue and “free to use” business models. As has been pointed by various experts, “free” means that you and I are the products. We retain minimal control over our data, and we are subjected to algorithmic ads, and social media news feeds that have caused large divisions in democracies ranging from the US to India and have spawned the phenomenon of fake news. What does decentralization mean to you? For me, decentralization is all about community control of the Internet where no single entity can establish hegemony over the Internet's resources and value. The decentralized Internet is one that is powered by a blockchain. How decentralization changes the Internet? Decentralized Internet unleashes the true power of what the net was meant to be - a resource that all users could use for their benefit.  The Internet can now store and transfer value, as demonstrated by various cryptocurrencies and assets. What is the best thing about decentralized Internet? A few interesting things are happening on the decentralized Internet. Centralized banking system has resulted in millions of people being excluded from financial services. The decentralized Internet and the resultant decentralized finance have allowed people without bank accounts to participate in the broader economy without paying undue fees. An often-quoted example is remittances, where intermediaries charge 5-8% of the remittance amounts from migrant workers who often earn minimum wage. Decentralized internet and stable crypto coins can help reduce the time and cost of money transfers. Financial inclusion: Nonfungible tokens have allowed artists to retain a larger share of their creative output without the need for intermediaries. NFTs have achieved popular appeal, which has led to more people adopting decentralized Internet and its constructs such as cryptocurrencies, wallets, automated exchanges, oracles, and the like. Artists and NFTs: Wallet as identity: The decentralized Internet requires public and private keys. The private keys are used to sign transactions (buy/sell/ transfer crypto or other assets). The wallets like Metamask used to sign transactions become a single point of truth to establish our identity as they store our private keys. Imagine logging in to any website without passwords and by connecting a wallet (with our private keys). Are you currently directly or indirectly working on the decentralized internet use case? We would love to know more about it. I am a firm believer in the future of Web3 and the value of education. Therefore, I am putting my effort to support , which is bringing high-quality blockchain programming training to the UAE and the broader Middle East. FutureU.co Education and awareness will help adopt the decentralized Internet and help people find jobs in this exciting arena. There is a huge talent gap, and companies are looking for people with knowledge of decentralized technologies, and I want to be helping bridge that gap. Do you have any apprehension or fear related to the decentralization of the Internet? I fear that there is a land grab going on in terms of creating and selling NFTs and minting Cryptocurrencies. I believe 90% of NFTs and Crypto coins will be worthless as they have been created with the sole aim of extracting value from unsuspecting speculators. This could have the impact of sullying the broader decentralized movement, which will completely transform the Internet as we know it. I advise people to deeply study the NFT and Crypto projects presented to them and only invest the amount they are willing to lose. These are the early days of the decentralized Internet, and financial pain will accrue to the uninformed. How do you see the future of the decentralized Internet? The future of the decentralized Internet is bright! A few things that excite me: Decentralized Autonomous Organizations are an alternate way to build the traditional companies. Here, the company's operating rules are built into code on a blockchain, and decisions are made by consensus by the community. The concept of a DAO can be extended to a nation, and one can potentially think of a country that is governed on the chain with its constitution and laws written in code.
