Concise who, what and why: In layman’s language ACQUIRES Transaction Overview On February 26th 2018, Circle Internet Financial (private), announced an crypto asset exchange, Poloniex (private) for approximately $400mm in consideration, according to . agreement to acquire Fortune Target Description offers a U.S.-based centralized crypto asset exchange allowing the trading of crypto assets. Poloniex support the trading of an unusually broad array of crypto currency pairs including 65 BTC pairs, 12 Etherium pairs, eight Ripple XRP pairs and 12 U.S Dollar pairs. From a perspective, most sources suggest Poloniex typically ranks between 10th — 15th with perhaps 1%-2% market share globally. Poloniex trade volume Poloniex was founded in 2014 by Tristan D’Agosta. Historically Poloniex has been quite secretive about its operations and therefore funding history and employee information not publicly available. Buyer Description Circle is one of the most well-known crypto businesses with substantial traditional venture and crypto specialist investor funding. Today, Circle offers two core products, i) a mobile app called Circle Pay which allows consumers to send money to friends and family without fees and ii) Circle Trade which offers institutions and large crypto investors digital asset liquidity as a market maker in the over-the-counter markets. Circle Trade caters to large crypto asset holders with a minimum order size of $250,000 and monthly trading volume over $2 billion. Circle also announced a third project in late 2017 named Circle Invest, which will offer consumers an easy to use app to invest in crypto assets. Circle Invest has not been released to-date. Competitors of Circle Pay include a broad variety of consumer payment apps such as Venmo, Paypal, Apple Pay, Facebook Messenger Payments and Zelle, among others. Circle Trade competes with institutional trading desks such as Cumberland Mining, Genesis Trading, IBC Group, ItBit and Octagon Trading. Competitors to the newly announced Circle Invest most notably include Coinbase/GDAX and Robinhood. In October 2017 Circle acquired which offered a mobile app oriented toward assisting retail investors with non-crypto asset portfolio management. Trigger Finance Circle was founded by Jeremy Allaire and Sean Neville in 2013. Jeremy Allaire has built several previous venture-backed businesses including Allaire and Brightcove. Circle has raised a total of $136mm in capital from Breyer Capital (Jim Breyer, former Accel), Goldman Sachs and IDC Capital Partners as lead investors in several rounds of financing. Other notable investors include General Catalyst, Digital Currency Group, Pantera Capital, Fenbushi Capital, among roughly a dozen others. Transaction Parameters Circle is acquiring Poloniex for approximately $400 million in consideration. The specific form of consideration was not disclosed but likely includes a considerable proportion of Circle equity given the size of the transaction. According to Fortune, the current run rate of combined company revenue is over $1 billion. M&A activity within the crypto marketplace is very early stage with no transactions of this size having been completed. Other, more modest crypto / blockchain M&A transactions have included in January 2018 which was also partially driven by unmet regulatory compliance requirements within crypto assets. BitGo’s acquisition of Kingdom Trust Strategic Rationale Circle’s ambition is to build a crypto-era financial services company. They intend to offer both consumers and sophisticated investors applications and services which allow crypto assets to be as easy to use as fiat currency and as easy to invest in as public equities. Today, essentially all crypto exchanges are secretive, unregulated and suffer significant trust and credibility issues. The strategic opportunity for Circle is to build a set of trusted, fully regulated and professionally managed products and services to serve the rapidly growing crypto asset market. Both consumers and sophisticated institutional investors equally benefit from the “maturation” of crypto from the wild west behavior that has been so prevalent to-date. While taking a slightly different tack, Coinbase is seeking to accomplish similar objectives. In this situation one can reasonably ask why Poloniex would consider a sale vs. continuing to build itself. As mentioned above, all crypto asset exchanges have experienced scaling and reputational challenges, including Poloniex. Building scalable infrastructure is challenging and it takes persistence, talent and capital. Also, as the SEC places a greater emphasis on regulating the crypto marketplace, it’s clear that they believe exchanges are subject to SEC and FINRA regulations and should be licensed as electronic trading marketplaces (ATS’s). This creates an even larger burden on a business which has been historically rather “freewheeling” in its operations. Circle offers Poloniex an opportunity to continue to build upon their potential as part of an organization with seasoned professionals, an ambitious vision for the future and have the financial resources and institutional credibility to succeed. Architect Partners’ Observations As the crypto market begins its maturation process, M&A will become increasingly commonplace. Not only for the traditional drivers of talent and capabilities enhancements but also as a mechanism to rebuild credibility and professionalism. While, Kyle Samani has many valid observations in his recently published , even projects which have issued tokens in ICOs will participate, both as acquirers and targets. perspective on crypto M&A Notes: The role of the cypto OTC marketplace is well summarized by .

Circle’s Acquisition of Poloniex

It’s funny how a seemingly meaningless event in one’s life can lead to an unexpected change. For me, one of those events happened in July 2021 when my flight home was delayed by so much that I paid for my very first Uber. I was so impressed by the experience that I wrote about the underlying payment processor in my “ ” article. I continued to dive deeper into the Marqeta platform, writing about how to and even an article about building a . Leveraging Marqeta to Build a Payment Service in Spring Boot: A How-To Guide create a rewards card buy now, pay later payment solution It was at that point I started talking with Marqeta about becoming a part of their engineering team. About six weeks later, I hung up my consultant hat and started as a full-time employee of a Fintech-based market disruptor that has created the world’s first modern card issuing platform. It’s been an exciting journey along a challenging, winding road. I love it! In my spare time, I have continued to dive deeper into the world of web3, and I am always eager to learn more about Fintech too. So exploring where web3 and financial services intersect is natural for me! For this article, I wanted to see how easy it is for a web2 developer to use Java in order to perform some Fintech transactions using web3 and USDC over the Ethereum blockchain. My plan is to use the Circle Java SDK, Java 17, and a Spring Boot 3 RESTful API. About Circle and USDC We can’t talk about USDC (USD Coin) without first talking about Circle, since they are the company that manages the stablecoin. Circle was founded in 2013 (around the same time as Marqeta) with a focus on peer-to-peer payments. As a private company, Circle has reached some key milestones: Circle Pay (mobile payments) allowed users to hold, send, and receive traditional fiat currencies. Later, they became a Bitcoin digital wallet service — allowing consumers to buy/sell Bitcoins. By 2015, a Circle account could be funded in USD via US-issued Visa and Mastercard credit cards and debit cards. Similar functionality was extended to Europe a year later. In 2018, Circle raised venture capital to establish USDC with the promise that its coin is backed by fully reserved assets. USDC is a digital (crypto) currency pegged to (and backed by) the US dollar. Basically, this means that 1 USDC is always equal to 1 US dollar. So why USDC then instead of US dollars? USDC can be sent, in any amount, for just a couple dollars. USDC can be sent globally, and nearly instantly. Because USDC is a digital currency, it can be sent, received, and settled at any time. You don’t have to worry about banking hours. And since USDC is digital — there’s an API and SDK to work with it (which is what we’ll explore in this article). USDC is issued by a private entity (it’s not a central bank digital currency) and is primarily available as an Ethereum ERC-20 token. With USDC, Circle aims to be a disruptor by giving customers the ability to avoid bank hours, processing times and costly fees — all while building a business with the USDC digital currency. Using USDC to Make and Receive Payments with Java? Yes, Please! For this publication, let’s assume your service caters to those interested in using USDC to perform financial transactions. From what you’ve observed, the current fees associated with using the Circle platform will allow your service to still be profitable. Still trying to keep this scenario realistic, let’s also assume that your infrastructure has its roots in Java-based microservices written in Spring Boot. Your infrastructure supports a proven infrastructure of web2 applications and services. To keep things simple, we will introduce a new service — called — which will act as the integration with the Circle platform. As a result, we will plan to explore the Java SDK by Circle — which is still currently in a beta state. circle-sdk-demo Demonstration Before getting started with the service, we need to navigate to the Circle’s Developer site and obtain an API key for sandbox use: https://app-sandbox.circle.com/signup/sandbox All I had to do is fill out this form: And then I received an API key for their sandbox: Keep the API key value handy, as it will be required before we start our new service. Creating a Spring Boot Service For this demonstration, I thought I would plan to use Spring Boot 3 for the first time. While I used the Spring Initializr in IntelliJ IDEA, the results of my dependencies are noted in the following file for the service: pom.xml circle-sdk-demo <dependencies>

} This service allows the following functionality to be performed: Obtain a list of balances for my API key Create a new payment Get an existing payment by ID Creating RESTful URIs In the example scenario, the will act as middleware between my existing services and the Circle platform. Next, basic controllers were created for the following URIs: circle-sdk-demo GET /balances POST /payments GET /payments/{id} For this example, I simply created the and classes to house these URIs.

} From the Circle , I can see a summary of all of my requests, including the response payload: developer logs screen Conclusion Readers of my publications may recall that I have been focused on the following mission statement, which I feel can apply to any IT professional: “Focus your time on delivering features/functionality that extends the value of your intellectual property. Leverage frameworks, products, and services for everything else.” - J. Vester When I look back on each of my web3 publications, I am always taken aback by the number of steps or complexity involved in getting from point A to point B. While I am sure this was the case when I started working with web2, I feel like the learning cost is much higher now. This is where Circle really seems to bridge the gap. In the example illustrated above, I was able to leverage Java and Spring Boot to integrate a RESTful API into the Circle platform and start making real-time, online, secure payments. As a result, Circle is helping me adhere to my mission statement. Things tend to move fast in technology fields, and early adopters are often faced with challenges like: Documentation that is not polished, accurate, or even available Tools and technologies with steep learning curves Inability to easily integrate with existing frameworks, services, and applications From what I found in this exercise, Circle has avoided these pitfalls – giving me the option to avoid bank hours, processing times, and costly fees – while building my business with the USDC digital currency. In addition to USDC, it also supports card payments, cryptocurrencies, and other digital payment methods. And it has distinct advantages over other payment technologies, such as Apple Pay, PayPal, and Google Pay. If you are interested in the source code for this publication, it can be found over at GitLab: https://gitlab.com/johnjvester/circle-sdk-demo Have a really great day!

In this tutorial, we will learn everything about NPM, npm scripts & packages, as well as, latest npm packages for developers to become more productive developers. Since Node.js was created, it has been sweeping the globe. Node.js has been used to build hundreds of thousands of systems, prompting the developer community to claim that . JavaScript is eating software The popular package manager npm, which allows JavaScript developers to share useful packages, is one of the main reasons for Node's success. There are millions of packages installed using npm per day, but as a beginner, we often don't know, what is NPM, and how to use it? That's why I'm writing this tutorial. What is NPM? Using npm efficiently is a cornerstone of modern online development to increase developer productivity, whether it's solely for Node.js, as a package manager or building tools for the front-end, or as part of processes in other languages and platforms. For a newbie, really grasping npm as a tool and understanding the underlying principles can be challenging - I spend a lot of time trying to figure out minute nuances that others would consider insignificant or take for granted. NPM is divided into two parts: Online repository for JavaScript packages. CLI application to install packages. (command-line interface) How NPM Dependencies are Delivered to Developers? The fulfillment center employs an army of dedicated servers, which will be assigned as personal assistants to each npmjs.com customer to help with this process. npmjs.com As a result, dependencies are supplied to JavaScript developers in the following format: The procedure for publishing a package for your JS friends would be as follows: That's why NPM delivers the desired packages to JavaScript developers quickly. Guide to package.json The file is a manifest of your project that includes information about the packages and applications it depends on, as well as special metadata like as the project's name, description, and author. package.json The file can be seen as a Passport with all the information about the user. This file is also send with the NPM package to the developer. package.json When is used to start a JavaScript or Node.js project, is also created with it. npm init package.json Metadata of Package.json Whether it's a web application, a Node.js module, or a simple JavaScript library, you'll nearly always discover metadata particular to the project inside a . package.json Metadata aids in the identification of the project and serves as a starting point for users and contributors seeking information about it. : There are several types of metadata in package.json : The name of the package choosed by author. name : Version displays the version of the package you are using. . version Initially, it is displayed as 1.0.0 : Description contains the description of the package, written by the author. description : The Project's License is stored on the license data of the package. license If you visit your , you will see all the information about the package, package.json this data is shown as: {

} How to edit file? package.json To update your file, you just need to go to the file in your code editor, preferably , and change the name, description, version, and license. After that, you can push your package. package.json Visual Studio Code and in dependencies devDependencies package.json The and flags on the command are used to install . They're intended for use in both production and development & test environments. —save —save-dev npm install dependencies Meanwhile, it's critical to comprehend the possible signs that precede the semantic versions: : the most recent minor release If the version is the most recent minor version of the 1 major series, a specification might install it. ^ 1.3.0 ^1.0.4 : the most recent patch release specification may install version if that is the most recent minor version of the minor series, just as does for minor releases. ~ ~1.0.4 1.0.7 1.0 ^ Learning with examples is always a better way to learn. . Let's hop on some of the examples of dependencies and devDependencies Here is an example of , that you will find on any Package: dependencies {
  "dependencies": {
    "@actions/core": "^1.2.3",

} There is a significant distinction between dependencies and the other common components of a package. The difference between Dependencies and is that they're both objects with multiple key & value pairs. package.json Every value in both and is the version range that's acceptable to install, and every key is the name of a package. dependencies devDependencies What is ? package-lock.json The exact versions of the dependencies used in an npm-based JavaScript project are described in this file. is an ingredient table, whereas is a generic descriptive label. Package-lock.json package.json is similar to how we don't usually read the ingredient table of a product. Package-lock.json file line by line. Developers are not supposed to read package-lock.json The command generates , which is also read by our NPM CLI tool to ensure that build environments for the project are replicated with . npm install package-lock.json npm ci Introduction to basic NPM commands There are tons of npm commands that are here to facilitate developers. Some of the most important, mainly , , and to be specific: npm install npm ci npm audit 1. npm install will, by default, install the most recent version of the package with the version sign. In the context of an npm project, will download packages into the project's node modules folder according to specifications, upgrading package versions where possible based on and version matching. npm install <package-name> npm install package.json If you want to install a package in the global context that you can use anywhere on your machine, you can use the global flag . -g Because npm has made installing JavaScript packages so simple, this command is frequently misused. 2. npm ci So, if is best for a production environment, is there a command that is best for my local development and testing environment? npm install —production is the way to go. npm ci Similar to how is generated whenever is called if it doesn't already exist in the project, uses this file to download the exact version of each individual package that the project depends on. package-lock.json npm install npm ci This is how we ensure that the context of our project remains consistent across machines, whether they are our development laptops or CI build environments like GitHub Actions. 3. npm audit NPM packages are vulnerable to bad authors with malicious intentions due to the large number of packages that have been published and can be easily installed. The npm.js organization came up with the idea of after noticing a problem in the ecosystem. They keep track of security flaws that developers can check their dependencies for with the command. npm audit npm audit informs developers about vulnerabilities and whether there are any versions with patches to install. npm audit is one of the most important functions for developers, who publish their own npm package. npm fund How to instantly initialize a npm Project? You can use the flag on the command to automatically populate all options with the default values if you want to get on with building your project and don't want to spend time answering the prompts from . --yes npm init npm init npm init You can simply use this command to instantly initialize your npm project: npm init --yes How to install modules with npm install? When you're first getting started with , one of the most basic things you should learn is how to install modules from . npm npm As you learn more about installing modules, you'll notice some differences, but here's the gist of what you need to know to install a standalone module into the current directory: npm install <module> Replace with the name of the module you want to install in the above command. <module> Conclusion This guide helps you with getting started with NPM, and some useful commands for beginners to know before getting started.

A Beginner's Guide to NPM Package Manager in 2022

Sorting is any process of arranging items systematically in a sequence ordered by some criterion so that you can analyze it more effectively. In this article, I want to describe a common method used to sort array elements in alphabetical and numerical order. In addition to general examples, I have provided a real-life use-case example to clarify the context of sorting array values. Introduction to Sort Array Elements Sorting is the process of arranging data into a meaningful order so that you can analyze it more effectively. For example, you might want to sort the data in a column to find the string "Alex" or you might want to order sales data by calendar month so that you can produce a graph of sales performance. Sorts are most commonly in numerical or a form of alphabetical (called lexicographical) order and can be in ascending (A-Z, 0-9) or descending (Z-A, 9-0) order. Why sorting data is important? Sorting is an important algorithm in Computer Science because it can often minimize the complexity of a task or simply facilitate the later search for members of the sorted set. These algorithms have direct applications in search algorithms, database algorithms, divide-and-conquer methods, data structure algorithms, and a variety of other areas. There are different sorting algorithms for different cases but they are not in the context of this article. Note: I think it's enough for the theory so let's dive into the practical part! Sorting Array Elements Alphabetically The very straightforward and easy way to sort array elements alphabetically is to use the Array.prototype.sort method. Ascending Sort The sort method sorts the elements of an array in place and returns the sorted array. The default sort order is ascending. The sort method needs an optional compareFunction(firstEl, secondEl) parameter that defines the sort order. If omitted, the array elements are converted to strings, then sorted according to each character's Unicode code point value. Let's look at the example below: names.sort(); const names = [ 'Williams' , 'James' , 'Alex' , 'Mason' , 'Ella' , 'Jackson' ]; // Sort the "names" array console .log(names); // Output: ["Alex", "Ella", "Jackson", "James", "Mason", "Williams"] You know, there are pointers in JavaScript. You can learn more about JavaScript Pointers on our Guide. JavaScript Pointers are actually as much important as  JavaScript Scope & Scope Chain. Descending Sort You can just as easily sort the elements of an array in ascending order, but if you want to sort the elements in descending order, use the Array.prototype.reverse method after the array has been sorted as the example below: names.sort(); names.reverse(); const names = [ 'Williams' , 'James' , 'Alex' , 'Mason' , 'Ella' , 'Jackson' ]; // Sort the "names" array // Reverse the "names" array console .log(names); // Output: ["Williams", "Mason", "James", "Jackson", "Ella", "Alex"] The reverse method reverses an array in place. The first array element becomes the last, and the last array element becomes the first. Be careful, the sort method is destructive. It changes the original array. If you want to overcome this problem, make a shallow copy of the array at first and then invoke the sort method as in the example below: Warning: copyOfNames.sort(); const names = [ 'Williams' , 'James' , 'Alex' , 'Mason' , 'Ella' , 'Jackson' ]; // Make a shallow copy of the "names" array const copyOfNames = [...names]; // Sort the "copyOfNames" array console .log(names); // Output: ["Williams", "James", "Alex", "Mason", "Ella", "Jackson"] console .log(copyOfNames); // Output: ["Alex", "Ella", "Jackson", "James", "Mason", "Williams"] Node.js is important for Developers to Use in 2022. Learn more about Node.js for Developers. To Speed up your Node.js App's Performance, you should learn how to create it optimal. You can learn about speeding your Node.js App. Sorting strings with non-ASCII characters For sorting strings with non-ASCII characters, i.e. strings with accented characters (e, é, è, a, ä, etc.), strings from languages other than English, use the localeCompare method within the compareFunction parameter of sort method. ES6 is important, You should learn about ES6 Code Snippets in minutes with our Tutorial. The localeCompare method can compare those characters so they appear in the right order. }); const items = [ 'réservé' , 'communiqué' , 'café' , 'adieu' , 'éclair' ]; items.sort( function ( a, b ) { return a.localeCompare(b); console .log(items); // Output: ["adieu", "café", "communiqué", "éclair", "réservé"] The localeCompare method returns a number indicating whether a reference string comes before, or after, or is the same as the given string in sort order. Note: Sorting Array Elements Numerically To sort numbers, you can use the Array.prototype.sort method, but as long as array items are converted to strings and compared in UTF-16 code units, all you need is a simple trick. But let's once sort an array of numbers without applying that trick and see the result: numbers.sort(); const numbers = [ 9 , 1 , 80 , 100 ]; console .log(numbers); // Output: [1, 100, 80, 9] The array got sorted alphabetically, so each integer actually got coerced into a string type. Then each string was compared, which is why 80 came before 9 and 100 came before 80 — strings are compared character-by-character. Have you ever thought of using Chakra UI & What are its Benefits? If not, you can learn more about using Chakra UI in 2022. The solution to achieve a numeric sort is passing a comparison (a, b) => a - b function to the sort method as a parameter. }); const numbers = [ 9 , 1 , 80 , 100 ]; numbers.sort( function ( a, b ) { return a - b; console .log(numbers); // Output: [1, 9, 80, 100] If the compareFunction parameter is supplied to the sort method, all non-undefined array elements are sorted according to the return value of the compare function. If a and b are two elements being compared, then: If compareFunction(a, b) returns a value > 0, sort b before aIf compareFunction(a, b) returns a value ≤ 0, leave a and b in the same order So, the compare function can have something like this under the hood: } } } function compare ( a, b ) { if (a is less than b by some ordering criterion) { return - 1 ; if (a is greater than b by the ordering criterion) { return 1 ; // a must be equal to b return 0 ; Ascending Sort To sort an array numerically in ascending order, the comparison function (a, b) => a - b should return the difference between the two numbers. const numbers = [ 8 , - 2 , 10 , 100 , 19 , - 4 , - 10 ]; numbers.sort( ( a, b ) => a - b); console .log(numbers); // Output: [-10, -4, -2, 8, 10, 19, 100] The comparison function (a, b) => a - b subtracts the second item from the first, returning a negative value if the second item is bigger, a positive value if the second item is smaller, and zero if the two items are equal. Descending Sort A descending sort would just need the operators reversed, so the comparison function becomes (a, b) => b - a. const numbers = [ 8 , - 2 , 10 , 100 , 19 , - 4 , - 10 ]; numbers.sort( ( a, b ) => b - a); console .log(numbers); // Output: [100, 19, 10, 8, -2, -4, -10] Use-case Consider the following array which each element of it is an object, holding two properties of name and score: ]; const results = [ { name : 'Edward' , score : 87 }, { name : 'Williams' , score : 50 }, { name : 'Andy' , score : 45 }, { name : 'Ella' , score : 75 }, { name : 'Alex' , score : 68 }, { name : 'Mason' , score : 37 } The use-case is to sort the results array once according to the names and once according to the score in ascending orders. Give it a try and then look at the solution! Arrays of objects can be sorted by comparing the value of one of their properties. Hint: Let's do it! As mentioned above in the hint, arrays whose elements are objects can be sorted by comparing the value of one of their properties. So let's start with sorting the results array according to the score property: }); // Make a shallow copy const resultsSortedAccordingToScore = [...results]; // Sort in ascending order resultsSortedAccordingToScore.sort( function ( a, b ) { return a.score - b.score; console .log(resultsSortedAccordingToScore); /* * (6) [{…}, {…}, {…}, {…}, {…}, {…}] *   0: {name: "Mason", score: 37} *   1: {name: "Andy", score: 45} *   2: {name: "Williams", score: 50} *   3: {name: "Alex", score: 68} *   4: {name: "Ella", score: 75} *   5: {name: "Edward", score: 87} */ As you see, the resultsSortedAccordingToScore has been sorted according to the score property. You can learn about JavaScript on our Website with #1 Programming Tutorials. In the next step, let's sort the results array according to the name property: } } }); // Make a shallow copy const resultsSortedAccordingToName = [...results]; // Sort in ascending order resultsSortedAccordingToName.sort( function ( a, b ) { let nameA = a.name.toLowerCase(); let nameB = b.name.toLowerCase(); if (nameA < nameB) { return - 1 ; if (nameA > nameB) { return 1 ; // names must be equal return 0 ; console .log(resultsSortedAccordingToName); /* * (6) [{…}, {…}, {…}, {…}, {…}, {…}] *   0: {name: "Alex", score: 68} *   1: {name: "Andy", score: 45} *   2: {name: "Edward", score: 87} *   3: {name: "Ella", score: 75} *   4: {name: "Mason", score: 37} *   5: {name: "Williams", score: 50} */ As you see the output, the array has been sorted according to the name property of the results array but was a little bit tricky. In the first step, I converted all the letters of name properties to lower case letters (or upper case letters) to do a case-insensitive comparison. The Alex and alex are different strings because a and A holds different Unicode code point values. Note: Conclusion The JavaScript sort method orders the elements of an array alphabetically in ascending order by default. The sort modifies an array in place which means the method does not return a new sorted array. In order to sort an array in descending order, instantly invoke Array.prototype.reverse method after the array has been sorted. In this article, I have broken down how to sort an array in JavaScript using sort method in either ascending and descending orders, both numerically and alphabetically, and at the end, I provided a real-life use-case example for a better understanding of the subject.

How to Sort Array Elements: An Essential Guide

Coding is hard! At least for me, it is very hard to get started with a new language. I remember when I started learning C++ as my first language after a horrible YouTuber told me to do so. This was my one of the biggest mistake that made my starting experience in coding horrible. Just like building something like a portfolio is hard, Coding is something you will need to build your portfolio. As time passed, I improved my skills and learned some tricks that made me better at coding: 1. Understand And Learn The Basic Concepts Before choosing a language to learn, understand the basic concepts that hold up all programming languages. These basic concepts are: As NPM is a very important for beginners to very advance. This tutorial will help you get started with NPM as a beginner. Because I skipped these fundamental concepts, I got stuck and had serious misunderstandings that made my progress very slow. 2. Learn By Building Projects I took some courses that gave me hands-on experience. There were times I just googled a tutorial and walked myself through it. Other times, I copied someone else’s project and modified it. For me, daily practice of writing codes and reading other people’s codes helped me develop my coding skills better. You may have a lot questions about Software Development. Here's a guide, which will help you answer all your questions about programming. 3. The Skill Of Googling Solutions To Problems Ever followed a tutorial word for word, line by line, as a beginner and still encountered problems? Maybe your result wasn’t the same as the tutorial you followed, you don't know what to do, and you keep asking what you did wrong. I experienced this more often than you can think (I still do). So, I had to learn how to Google better. One tip that works for me is paying attention to what search results look like when I run a query and examining them closely to know if I should click through the page. 4. Bookmark Useful Pages Bookmark a page and flip it open whenever you need it rather than memorizing it. Although some conceptual materials you should try to understand to the best of your ability, but when concepts such as parameter lists, function names, and others, it is okay to look them up on a reference sheet. I have over a hundred pages that I’ve bookmarked to various guides, tutorials, and APIs. For example, I recently wanted to learn Artificial intelligence, but I still have a lot of questions about how can I get started with AI and What should I do? Here I searched about it on google, and Bookmarked important solutions, which later help me understand AI. 5. Take A Break Whenever I get stuck while working on a project and feel the frustration building up, I give myself a break. When I come back to that project, I look at it with fresh eyes. This practice helps me think more clearly. If you want to know about more programming some helpful tips about programming, you can reading our programming tutorials ➡ On DeveloperNoon.com Conclusion These tricks that worked for me probably will not work for you. Every individual has their own way to become an awesome developer, just put in the hard work and enjoy what you do, and don't take the stress.

20 JavaScript Libraries Every Programmer Should Know

Mass adoption of Bitcoin by the general public won't happen because governments and institutions decide to buy Bitcoin en masse. This will add more intermediaries between the people and Bitcoin. Satoshi Nakamoto initiated the Bitcoin revolution to free us from these intermediaries. Bitcoin is there to make you independent of governments and central bankers. Bitcoin is a true unit of wealth, unlike fiat currencies which are units of debt. Mass adoption of Bitcoin can therefore only be fully realized through awareness of the problem represented by the fiat system and the solution represented by Bitcoin. This awareness will take time at first, but it will accelerate sharply when the time comes. To accelerate this awareness in a way that respects the profound objectives of the Bitcoin revolution, I urge you to enter fully into the virtuous circle of mass adoption of Bitcoin. This virtuous circle is represented by the 5 “S” of Bitcoin. Study Bitcoin Bitcoin is unlike anything we know. Bitcoin is a major technological and monetary disruption. To truly understand the liberating power of the Bitcoin revolution, there's no secret: you have to study Bitcoin long enough for it to click inside you. Once it does, nothing will ever be the same for you again, and you'll be on your way to opening your eyes to 7 essential truths about how Bitcoin will change your worldview on every level. The more you understand about Bitcoin, the more you'll realize that you absolutely must keep an open mind and always remain humble in the face of this unique revolution. Never hesitate to ask questions, so you can continue to expand your knowledge. That's what the Bitcoin revolution teaches you too. Save in Bitcoin Bitcoin is the best savings technology in history. Nothing more, nothing less. Bitcoin allows you to secure the fruits of your labor. Bitcoin lets you detach yourself from the clutches of mass consumerism and refocus on your own needs. It's no coincidence that Bitcoiners generally end up adopting a frugal lifestyle. No more questions about investment strategies, Bitcoin gives you back the ability to save without the need for specific knowledge. A game-changer for everyone. Ultimately, you can acquire Bitcoin through mining, through your work, or by exchanging weak money for BTC. All options are on the table, and it's up to you to take advantage of them to secure the fruits of your labor and live your life on your terms. Secure Your Bitcoin Bitcoin gives you access to great power once you take possession of the associated private keys. But with great power comes great responsibility. It's always like that in life, but with Bitcoin, it's worth it. Bitcoin allows you to become a self-sovereign individual. Once you have the private keys to your Bitcoin, no one can stop you from using it as you wish. You protect yourself from censorship by the powerful people at the head of the current system. Everyone needs to realize this and get their Bitcoin off the exchanges and into cold storage. This is the only way to truly access the liberating power of the Bitcoin revolution. Spend and Replace Your Bitcoin Bitcoin isn't just a great SoV. It's also, and above all, an MoE. For Bitcoin to become an everyday MoE for as many people as possible, you need to stop with the paradigm of Bitcoin's first decade: “HODLing Bitcoin”. Instead, you need to adopt the new paradigm I described back in 2023: “Spend and Replace your Bitcoin.” This paradigm supports the development of a circular economy based on the Bitcoin system. It also encourages more and more merchants around the world to offer Bitcoin as an MoE. This is how the Bitcoin revolution will reach its full potential. Spread Your Knowledge on Bitcoin Bitcoin is a revolution for the people by the people. Of course, Satoshi Nakamoto initiated this revolution, but he had the intelligence to leave his place by offering this nascent revolution to the people. It was then up to the people to make the best possible use of it. And it's fair to say that, so far, the people have not failed to drive the Bitcoin revolution forward. The challenges remain numerous, and the risks are great, but the Bitcoin revolution continues to progress block by block. Once you've understood the why of Bitcoin, but also the fact that you need to remain constantly open-minded to increase your knowledge, you'll also realize that since Bitcoin doesn't have a dedicated marketing team, it's up to every one of us to help others open their eyes to the Bitcoin revolution. Not by forcing the hand of those who aren't ready to understand the why of Bitcoin, but rather by getting them to think about the flaws in the current system, the way money works, or the unique game-changer represented by the Bitcoin system. It was with this in mind that I wrote my book “The Truth About Bitcoin.” In this book, I'm not trying to convince anyone to make one choice or another about Bitcoin. On the contrary, I encourage readers to think for themselves and form their truth about Bitcoin. I present facts, opinions, and ideas that should feed the reader's thought process. At the end of the book, it's up to everyone to decide what to do with Bitcoin. This book is in total harmony with one of the essential objectives of the Bitcoin revolution in my eyes: to teach you to make your own decisions and become self-sovereign individuals. Mass adoption of Bitcoin by the general public won't happen because governments and institutions decide to buy Bitcoin en masse. This will add more intermediaries between the people and Bitcoin.

The Truth About Bitcoin In this book, I'm not trying to convince anyone to make one choice or another about Bitcoin. On the contrary, I encourage readers to think for themselves and form their truth about Bitcoin. I present facts, opinions, and ideas that should feed the reader's thought process. At the end of the book, it's up to everyone to decide what to do with Bitcoin. This book is in total harmony with one of the essential objectives of the Bitcoin revolution in my eyes: to teach you to make your own decisions and become self-sovereign individuals.

The 5 "S": How They Makes Up The Virtuous Circle of Mass Adoption of Bitcoin

The DS Acronym: DolphinScheduler or DeepSeek Once upon a time, when people in the tech circle mentioned DS, what came to mind was a lively “little dolphin” - Apache DolphinScheduler (abbreviated as DS). This distributed task scheduling system, born in 2019, was once the “dream job” for big data engineers with its visual DAG interface, multi-tenancy support, and deep integration with the Hadoop/Spark ecosystem. However, the wheels of fate began to spin rapidly in early 2025: Hangzhou AI company DeepSeek (Deep Quest) burst onto the scene with its inference model R1 and open-source large model V3, touting “low cost and high performance.” Not only did it sweep the capital market, but it also redefined the acronym “DS” overnight - from now on, “DS” was no longer a scheduling tool but the “new darling” of the AI circle. Some developers joked, “When I used to write DS configuration documents and colleagues asked, ‘What is DS?’ I would reply, ‘Dolphin Scheduler.’ Now when I ask, they immediately respond, ‘Oh, that AI that writes poetry more emotionally than Qu Yuan?’” The “Top-Flow Battle” in the Tech Circle: DolphinScheduler's Grievance and the AI Newcomer's Ambition 1. DolphinScheduler: The Forgotten “Original DS” As the “old-timer” in the big data scheduling field, DolphinScheduler should have comfortably held the throne of the acronym. Its distributed architecture and drag-and-drop DAG design once conquered countless ETL engineers, even rivaling Airflow. However, its user profile has always been that of a “behind-the-scenes hero” - busy daily solving Spark environment variable errors, debugging email alert nicknames, or going crazy when ZooKeeper nodes crash. This “hardcore but low-key” image has kept the DS acronym confined to technical documents, never breaking through the circle. 2. DeepSeek: The “Acronym Hijacker” in the AI Circle In contrast, DeepSeek made its debut with its own buzz: low-cost models (training costs only one-twentieth of GPT-4), domestic GPU compatibility (11 manufacturers competing for cooperation), and even the ability to analyze trade war policies while reciting “The Mountain Spirit” to move users. What's more “unfair” is that it took only a week to make “DS” a hot word on social media, with even sensational bloggers discussing “DS's RL technology breakthrough.” Netizens joked, “DS used to be the acronym for programmers staying up late to fix bugs; now it's the code for AI poetry that trends on hot searches.” The “Technical Philosophy” of Acronym Collision: The Battle Between Tools and Traffic This acronym dispute is essentially a collision between technical value and traffic hegemony: DolphinScheduler represents the long-termism of basic tools - it quietly supports data pipelines but is too “practical” to lack explosive highlights.
DeepSeek interprets the traffic law of the AI era - using emotional interaction (such as poetry empathy) and capital storytelling (such as “the rise of domestic GPUs”) to quickly occupy the mind. Some developers complained, “When I used to use DS for scheduling tasks and my boss asked, ‘What's the use of this tool?’ Now when I use DS (DeepSeek) to write weekly reports, my boss praises, ‘This AI is reliable.’” Peace Proposal: How to Achieve “Common Prosperity” for the “DS” Acronym? Faced with the acronym collision, the tech community has put forward the following “peace initiatives”: Scenario Isolation Method

Big data engineers insist: “DS (DolphinScheduler) schedules tasks, DS (DeepSeek) writes PPT,s clear division of labor, no interference.”
AI researchers retort: “DS (DeepSeek) can tune parameters, DS (DolphinScheduler) can schedule tasks, the combination is the perfect entity!”


Suffix Differentiation Technique

It is proposed to rename DolphinScheduler as “DScheduler” and DeepSeek as “DSeek,” but the public rejected it, saying, “Why not just call them ‘Dolphin’ and ‘Deep Sea Fish’ to avoid internal competition?”


Ultimate Mysticism


Developers suggest: “Let DolphinScheduler integrate with the DeepSeek model to generate poetic logs for scheduling tasks - keeping the acronym while riding the traffic wave.” Example:

Task node 14451413115008,Failed as resolutely as Qu Yuan throwing himself into the Miluo River,But don't panic, after three automatic retries,Finally, ‘SUCCESS’ illuminates the mountains and rivers! The War of Acronyms, the Symbiosis of Technology Perhaps, the battle over the “DS” acronym is a microcosm of technological evolution: DolphinScheduler reminds us that the value of basic tools never fades - even if the acronym is “stolen,” it remains the unsung hero of the data pipeline.
DeepSeek proves that breaking through the circle in technology needs “poetry and the distance” - an AI that can write code is common, but one that can empathize with Qu Yuan is rare. Finally, an appeal to all developers: If you happen to encounter a confused newcomer asking, ‘What is DS?’ Please kindly reply:——For big data, use Dolphin; for AI, use Deep Sea Fish,Both are DS,But it is recommended to check the documentation first,To avoid awkward conversations in meetings.

Tech Circles Can't Decide What 'DS' Stands For

People are living in shopping malls. The once-beacons of capitalism and leisure, the American shopping mall, went from being almost totally vacant and abandoned to being restored as indoor residential communities. https://youtu.be/J1GIF6VNipE?si=XM8pnAnsgS69mBDn&embedable=true To give you a brief history: Arcades were shopping malls in 19th-century Paris. Some of these arcades still exist to this day. Arcades are a series of architectural arches that make up a pathway. Perhaps the most notable points of interest concerning arcades pertain to the very word itself. The term "arcade" contains the French root "arc," relating to an "arch" or "bow." This makes sense when we think of the first arcades as simply a series of arches within an architectural structure. You may have noticed these repeated arches or arcades in the Colosseum of ancient Rome or perhaps in your local mosque or church. Not only does the "arcade" relate to architecture, but it was later used to describe shopping centers or "shopping arcades." In his unfinished, posthumously released work "The Arcades Project," philosopher Walter Benjamin collected various writings about the glass-roofed, iron-covered centers built for leisure and commerce in Paris during the 1930s. This eclectic collection is seen as a framework for post-modernist thinking. It is partly because of this architectural relation that arcades can directly reference shopping malls. Of course, in the modern era, underneath these arches and within shopping centers, we also encounter the type of "arcade" we are more familiar with—the video arcade. Fast forward to today, those very arcades of antiquity, which became the American shopping malls of the modern era, were abandoned and turned into liminal spaces—haunting thresholds with no purpose. Now, they are being reported to have become residential areas, bringing people together as communities under one roof. Isn't it ironic that the concept of Arcadia as a utopia became one of commerce and merchants, only to eventually return to the symbolism related to the utopian society of myth? By 2022, 192 U.S. malls planned to add housing. Lafayette Square Mall in Indianapolis will open apartments, including affordable housing, in a former Sears by 2025. The Arcade Providence in Rhode Island, America’s oldest mall, was converted into micro-apartments and retail spaces years ago. This shift is reshaping Arcadism theory.  Malls—once utopian shopping hubs—declined with tech advances and are now being reborn as places to live. A fascinating full-circle moment. The benefits of these indoor shopping centers as living spaces include the accessibility and utilitarian architectural design that incredibly designed shopping centers facilitate. Through capitalism and innovation come peaks of utopian ideology. This story is still very much ongoing and will be covered in my future works on Arcadism. People are living in shopping malls.
