"Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning." - Rich Cook, The Wizardry Compiled.
In this article, I will be explaining in depth how the copyToClipboard snippet from 30 seconds of code works. You can find the source code for it and a ton of other useful methods in the project’s repository.
Programming has been one of the most in-demand and highly-paid skills for the last two decades, and the demand is only increasing. In addition to this demand and popularity in the market, working as a developer also provides a lot of flexibility. You can work from wherever you want and contribute to projects all around the world. All of these reasons make software development highly compatible with the freelancing lifestyle.
If you’re an enterprise architect, you’ve probably heard of and worked with a microservices architecture. And while you might have used REST as your service communications layer in the past, more and more projects are moving to an event-driven architecture. Let’s dive into the pros and cons of this popular architecture, some of the key design choices it entails, and common anti-patterns.
Web development seems to be a diverse & ever-changing field. New technologies and tools come up regularly, due to which app programmers and developers have to face the dilemma. They get confused between the long term and mature solutions & the new upcoming ones.
Recently I wanted to add a multi-step form to my site. Since my site runs on Hexo, a static page generator, I had some doubts about how to execute this task. I already had a static form on my site, and I didn’t want to spend too much time on the development of features like steps, show/hide logic or validation.
JavaScript is a beautiful language. You must believe I’m crazy. Maybe you’re crazy for agreeing with me. But why would I say something like this? As a language, JavaScript gives you no support whatsoever. It bites your head off if you give it the slightest chance, and it has bizarre error messages if left unhandled. So you tell me, why is it beautiful?
Hi guys, I’m a Front-End developer. Before there was a time 2 years working CMS Magento, I like CMS Magento because system clean, and architecture database EAV (Entity — Attribute — Value) but I don’t understand why present I’m dev front-end (I don’t know) in the 2-year current. And present I chance comeback working position Back-End that I like.
There are some great tools and extensions that might help your coding experience enjoyable in the VS Code.

That is why this article is here to help you with some of the most useful shortcuts for faster coding.
Understanding bit manipulation provide new approaches you never knew existed to solve a particular problem. Let us do what’s necessary to start developing this bit-wise approach.
Learning how to code is something I’ve thought about doing for some time but always found an excuse for putting it off. Then the pandemic happened, flipping my schedule upside-down. If I was serious about wanting to learn, then this was the perfect opportunity. It was time for my next 30-day challenge.
"Browser based bundler" is a very interesting topic.
For example, can we compile the webpack code in the browser instead of the server's nodejs environment? The advantage of this is that we don't need the server's resources for compilation.
There are different solutions to this problem. For example, codesandbox, which defines a browser-based compilation strategy, can be used to package reacts, vue, etc. in the browser. It can also be easily understood that codeandbox does a browser version of webpack.
But the question is, can we execute webpack in the browser instead of doing a new one? Even implementing some webpack-based libraries?
There is a very early webpack issue discussing it . But this demo is too old to run the latest version of webpack.
I am wondering if we can do a browser environment to simulate running Node.js. Node.js and Chrome is both v8, and many of the Node.js lib code can be executed in Chrome. In addition, I found some cool libraries, such as BrowserFS, memfs, rollup-plugin-node-builtins, etc. These libraries can help us build this environment. But there is a key module, Node.js "module" is not available, we need to modify it from Node.js. Node.js supports cjs and esm, but to simplify the problem, I only develop the cjs module for the time being. Next, combine all the modules and try to run the simplest Node.js demo.
Let’s dive in to learn about object-oriented programming and functional programming. What is object-oriented programming/OOP? What's functional programming/FP?
Fetching data from internet is one of the most common operations that every developers should master. In Flutter, this operation is pretty straightforward. In this post we will learn how to handle data from fetching to displaying it on our mobile apps.
According to a not-at-all recent report by Keeper, there’s a 50/50 chance that any user account can be accessed with one of the 25 most common passwords.
If you’re a microservices developer considering communication protocols, choosing an event-driven architecture might just help you rest a little easier at night. With the right design, event-driven architecture can help you to create apps that are decoupled and asynchronous, giving you the major benefits of your app being both performant and easily scalable.
I think many web developers and server administrators had been facing the 301 redirection cache. I had facing it very often until I learn the lesson…
I hope it helps you and you learn something from me, not from your mistakes 💥
So I’m on zero sleep. I decided last night at 3am that it wasn’t worth waiting in bed, hoping to fall asleep anymore, having to wake up at 8am anyway. Being incredibly tired, beyond tired, loopy even, I think, “what to do?” I don’t have much to do to pack before my flight tomorrow, and I’m useless for anything productive...maybe a little Factorio?
During past couple of years I have worked on few projects written in GO. I noticed that the biggest challenge developers are facing is lack of constraints or standards when it comes to project layout. I'd like to share some findings and patterns that have worked best for me and my team. For better understanding I'll go through steps of creating a simple REST API.
If you’re new to programming, are a computer teacher, or just a parent planning to get his child started with programming – you must be wondering where to start. C++, C, Java, Python – there are just too many options out there! While all these languages are great in their own right and popular, the debate between C++ and python has been intense for sometime.
The process of preparing for coding interviews is anxiety-inducing for many developers. There’s so much material to cover, and often much of it feels irrelevant to what devs are doing in their day jobs, which only adds to the stress.
It’s a remarkable beast of a tool, Node.js. If you’re a beginner, aspiring coder, or IT student, it may be hard to wrap your head around it, but when you eventually get used to it, it’s eyeopening. This tutorial will walk you through the basics of API design, teaching you how to set up the backbone of a REST API and how to structure your code in a logical manner.
Hello everyone, Google recently released MaterialDatePicker: a useful new component that complies with the material design guidelines(https://material.io/components/pickers/#usage). This new component has a very interesting feature that allows you to select a date range instead of the old flow of selecting two dates: one "from" and one "to, i.e the component can be used as a DatePicker and a DateRangePicker. I was very excited about this and i wanted to use this in an update to a project i work on: to improve the user experience, sadly i could not find any examples or tutorials on using this lovely new component. So, I decided to make one, in this article I will be outlining the steps I took to make use of the MaterialDatePicker. This would be a really short article since, the MaterialDatePicker is really very easy to use.
The Pick utility Type lets us take types based off existing ones, by selecting specific elements from them. Let's look at how it works and when to use it.
We can use LinkedList to merge both sorted lists, though there are considerations to doing it single or double-linked that may complicate the operation.
This is a long and winding tale (with lots of code) of my attempts replicate JSX syntax, component structure, server-side rendering, and React’s update magic with VanillaJS.
Recently I needed to delete some documents that I saved in MongoDB after some time. I can think of a few examples of why we would want to delete data after some time:
Below is a small gif of what we will be building. A simple search box that allows us search through a contact list. We would be using functional components rather than class based components to achieve this.
To learn coding is not just being familiar or comfortable with the syntax but to understand the logic and improve logical and analytical skills. Every programming language has advantages and disadvantages but the basics are the same to a certain extent. We all know that the best method to learn a programming language is writing codes in it. It is also known that the key developers not just write the code but enjoy doing it. If the basics are not sorted, advanced programming tends to be boring.
In this tutorial, you will learn how to make gradient app bar in flutter ? Before start anything, In every code we need a page for contain our whole source code. So let’s start…
Over a decade ago I completely changed the trajectory of my life from becoming a lawyer to becoming a programmer. I learned from a C++ book then made some pathetic iOS apps for about 4-5 months. I then moved to Silicon Valley to start my career. I'm sure you're reading this thinking 'what a genius!', but sadly the truth is far from that. I'm definitely proud of what I've accomplished but often think about the missteps I made along the way and continue to make to this day.
There is no programmer in the world who knows how to solve every coding problem. That person simply doesn’t exist, because the programming field is so big that to a normal person, it would take two lives to learn all of that, but we only have one life.
Programming CUDA using Go is a bit more complex than in other languages. Although there are some excellent packages, such as mumax, the documentation is poor, lacks examples and it’s difficult to use.
How to Find the Product of All Elements in an Array Except Self? You must write an algorithm that runs in O(n) time and without using the division operation.
What do you think, how long do programmers actually work per day? Most people would say that the answer is 8-9 hours. Some say that they work 12 hours or more per day. While that is somewhere true, it’s not the amount that most programmers actually work, because you can’t consider browsing the web as working, right?
Whiteboard-style interviews are ubiquitous in the tech industry. For those who not had the pleasure, whiteboard interviewing is the practice of asking candidates to solve technical questions on a whiteboard, piece of paper, or computer during the interview. This kind of environment can feel like a pressure cooker and cause even the most competent engineer to fall apart.
You are not a programmer. You have zero coding experience. You probably consider yourself “not a math person”. So let’s find out how you can learn Python, even if you’ve never had any exposure to a programming language.
Genetic Algorithms , also referred to as simply “GA”, are algorithms inspired in Charles Darwin’s Natural Selection theory that aims to find optimal solutions for problems we don’t know much about. For example: How to find a given function maximum or minimum, when you cannot derivate it? It is based on three concepts: selection, reproduction, and mutation. We generate a random set of individuals, select the best ones, cross them over and finally, slightly mutate the result - over and over again until we find an acceptable solution. You can check some comparisons on other search methods on Goldberg's book.
These 9 tips will help you improve the performance of your React code so that you can make the most out of your software and maximize what you are capable of.
The focus on enhancing the developer experience is evolving rapidly post COVID, as businesses embark on the digitization journey. What really does this entail?
Edit: I have been getting quite a bit of feedback interpreting this article to mean that recursive functions are bad and iterative methods are always better. This couldn’t be further from what I believe — This article simply aims to discuss iteration as an alternative tool!
HTTP is a stateless protocol and is used to transmit data. It enables the communication between the client side and the server side. It was originally established to build a connection between web browsers and web servers.
How to prep for coding interviews by using patterns to figure out how to guess the most likely questions to be asked in many programming job interviews.

This post and the creation of the telegram channel were motivated by the lack of detailed information about interviews for Front-End engineers in the USA.
I'm gonna out on a limb here and assume that you know the basics of how a web server works when you clicked on the title of this post. Basic knowledge of vim would be helpful too.
First of all, what are all these words - Statically - Dynamically - Strongly - Weakly Typed Languages?
This is how you can classify programming languages:
You might think a profession based on logic and learning would be immune to folklore, but the developer community remains rife with myth — myths so pervasive they begin to manifest into reality.
All data in computer is represented in binary i.e. in 0 or 1. Computers or machines do not understand our languages, they understand bits. Generally programmer do not care about operations at the bit level. But sometimes a programmer has to dive in a deeper level and work on bits.
In the past few years, the programming language that has got the highest fame across the globe is Python. The stardom Python has today in the IT industry is sky-high. And why not? Python has got everything that makes it the deserving candidate for the tag of- “Most Demanded Programming language on the Planet.” So, now it’s your time to do something innovative.
Nowadays every one of us is facing REST APIs by either developing or consuming such a service. Also, we’re in the trendy era of microservices, where we splitting our business logic into small separate services independent from each one. Mostly these services follow RESTful principles and using the JSON format for communication, which became the most widely used format, because of its simplicity.
A couple of weeks ago I wrote an article about building and deploying a Blazor app without touching a Windows machine and realized maybe I should take a step back and explain what Blazor is and why anyone would use it. It's still fairly new to most in the front end development world, but it's awesome and you should check it out.
While this anecdote is from my own experience, I firmly believe that most of us been in this situation before. One day, you decide to learn something new. Perhaps you want to learn how to code, so you pick the hottest language of the moment. It's a language that "pays the most", works like magic, and everyone is looking for people that know it.
I still remember my first day at Outbrain. As part of the Bootcamp (training program), we were required to clone the code from a repository called the trunk (one monolithic repo that contained all our codebase). It took at least half a day to clone and build the whole source code. Over the next year or two in which my team worked with a monorepo, we just suffered — cloning the repo was time-consuming; the slow build/release time frustrated us; flaky tests and bad commits affected all the engineering; and let’s not even mention the IntelliJ indexing time, which easily afforded us time to run down for a chatty coffee break.

The Python TypeError: 'int'object is not interable is a common error that can be caused by using a loop without the range() method. It can be easily fixed.
The other day I was interviewing at one of the companies, and I was asked the following question, how can you count occurrences of a word in a 50gb file with 4gb of RAM. The trick is to not load the whole file into memory and keep processing each word as we keep on moving the pointer of the file. With this, we can easily process the whole file with a minimal amount of memory resources.
Hi guys, I want to introduce use-places-autocomplete. It's a React.js hook for Google Maps Places Autocomplete. With it you can build your own places autocomplete UI like the following demo easily! Hope you guys 👍🏻 it.
Fear not, this isn’t another mildly aggressive blog post telling you that you’re inferior; I’m not here to tell you what you don’t know about web development.
Today, with open source machine learning software libraries such as TensorFlow, Keras or PyTorch we can create neural network, even with a high structural complexity, with just a few lines of code. Having said that, the Math behind neural networks is still a mystery to some of us and having the Math knowledge behind neural networks and deep learning can help us understand what’s happening inside a neural network. It is also helpful in architecture selection, fine-tuning of Deep Learning models, hyperparameters tuning and optimization.

Do you know that along with CSS and HTML, JavaScript is one of the 3 main things of the World Wide Web? It facilitates interactivity to the web app pages, therefore, it is extremely crucial for web applications. A majority of web applications use this tool and all the major web browsers have a dedicated JavaScript engine to execute this.
This article will introduce functional programming concepts that every programmer should know. Let's begin by defining what functional programming is (FP from now on). FP is a programming paradigm where software is written by applying and composing functions. A paradigm is a "Philosophical or theoretical framework of any kind." In other words, FP is a way for us to think of problems as a matter of interconnecting functions.
When it comes to the project and its realization, you should take into consideration lots of aspects. And the choice of the technology stack is one of the crucial things that can define how successful and smooth your project will be. Depending on the idea and requirements of your application, site or product, you may find and select a proper programming language (PL).
CPU, also known as the microprocessor is the heart and/or brain of a computer. Lets Deep dive into the core of the computer to help us write computer programs efficiently.
If you’ve adopted Linux, chances are you might have done so for development purposes. After all, it has everything you need to program in most languages, and do so for (almost) free.
Data science and machine learning are the two main things Python is perfect for. Code simplicity, higher salary, and automation are just some of the best reasons to Learn Python, if you're on the fence about it.
In this article, we’ll be deep-diving on how to build Apache Superset from the source. The official documentation is too complicated for a new contributor and thus my attempt to simplify it.
Well, I had done some javascript development(node.js) in the past but javascript has changed a lot after ES-6. TIll now my main focus has been backend development in java and ruby(RoR mainly). I am going to share my experience on writing my first react native app.
Time is always a scarce resource for developers. From aggressive deadlines, to multiple projects, to unexpected requirements, our time is constantly in demand. That's why we're always on the lookout for tools and processes that help us boost productivity. In this article, we'll look at five web development tools that might just give you that extra boost in productivity you need.
With the massive increase in the volume of data on the Internet, this technique is becoming increasingly beneficial in retrieving information from websites and applying them for various use cases. Typically, web data extraction involves making a request to the given web page, accessing its HTML code, and parsing that code to harvest some information. Since JavaScript is excellent at manipulating the DOM (Document Object Model) inside a web browser, creating data extraction scripts in Node.js can be extremely versatile. Hence, this tutorial focuses on javascript web scraping.
If you are a Python programmer, it is quite likely that you have experience in shell scripting. It is not uncommon to face a task that seems trivial to solve with a shell command. Therefore, it is useful to be familiar with how to call these commands efficiently from your Python code and know their limitations.
Golang is a concurrent programming language. It has powerful features like Goroutines and Channels that can handle asynchronous tasks very well. Also, goroutines are not OS threads, and that's why you can spin up as many goroutines as you want without much overhead, it's stack size starts at 2KB only. So why async/await? Async/Await is a nice language feature that provides a simpler interface to asynchronous programming.
Flutter has been booming worldwide from the past few years. While there are many popular mobile app development technologies out there, Flutter has managed to leave its mark in the mobile application development world. In this article, we’ve curated the best Flutter app templates available on the market as of July 2020.
Gartner predicts that by 2022, more than 75% of global organizations will be running containerized applications in production, which is a significant increase from fewer than 30% today
You’ve probably seen somewhere someone saying coding vs scripting. When I first saw that, I thought that those two are the same things, but the more I learned I found out that there are some main differences between those two. So, what are those differences?
In this, we share the complete guide for React Hooks. Here you read about useCallback and useMemo with their syntax. If you are learning React then this for you

It’s time for a web project that has real-life uses.Today I’ll show you how to make a feedback form using a website, a PHP engine, and some mailing magic. Why?
It's been a long time since Hypertext Markup Language (HTML) showed up to become the basis of the web. Since that time, many things have changed, and some features of the HTML files went from desirable to negative. Thus, a cryptic markup or an obfuscated source code once considered useful things to avoid unauthorized copies, seems to be a nonsense in the fight for positioning in search engine results that we live in today.
Chatbots are extremely helpful for business organizations and also the customers. The majority of people prefer to talk directly from a chatbox instead of calling service centers. Facebook released data that proved the value of bots. More than 2 billion messages are sent between people and companies monthly. The HubSpot research tells that 71% of the people want to get customer support from messaging apps. It is a quick way to get their problems solved so chatbots have a bright future in organizations.

In this tutorial, we are going to learn how to record and play audio to React Native apps. We are going to build a simple screen that supports features such as recording audio, playing audio files, pausing and resuming, as well as resetting audio streams. The final app will look like the image below.
Bulma is a free, open-source CSS framework based on Flexbox and used by more than 200,000 developers. It's the easiest to learn (my opinion) due to its natural naming of classes and a simple grid system. It's not that popular like Bootstrap, but it got a specific fanbase.
Image credit— Grokking the Coding Interview: Patterns for Coding QuestionsHello all, I have been sharing a lot of coding interview questions for Programmers who are actively looking for Job, particularly for beginners and computer engineers who have just graduated and has no real job experience.
I often receive questions like which is a first programming language to learn? Is Java a good programming language to start with?, how good Java is as a first programming language? which is the best programming language for beginners, or shall I start with Java or Python?.
I've read many articles on procrastination and motivation, but I've always found in them a complete or partial misunderstanding of the problem. Or just inconsistency with my realities – after all, people are different. I'm going to describe what I know from my own experience and what helps me personally. Maybe it will help someone else.
DevOps is one of the most in-demand skills from employer and there are many job opportunities lying for full stack developers, distinguished engineers and DevOps professionals. If you are an experienced Java programmer or a full-stack web developer, and want to become a DevOps engineer then you have come to the right place.
These days REST API has become a web applications development standard, allowing to divide web development into two separate parts. There are several mainstream frameworks like Angular, React, Vue, that are used for UI. Backend developers are free to choose from large variety of languages and frameworks. Today I’d like to discuss NestJS framework. We’re going to create a simple CRUD application using Nest and the @nestjsx/crud package.
The invention of SOLID principles began in the late 80s. Robert C. Martin started to develop these principles while arguing the principle of software design on USENET (an early kind of Facebook). After addition and subtraction, Robert C. Martin formulated the principles in the early 2000s. It was until 2004 that the principles were arranged and called SOLID principles. It is an acronym that stands for five specific design principles.
Need to encrypt some text with a password or private key in Python? You certainly came to the right place. AES-256 is a solid symmetric cipher that is commonly used to encrypt data for oneself. In other words, the same person who is encrypting the data is typically decrypting it as well (think password manager).
A little backstory on how this started. My team needed to save some on money on the infrastructure we were requesting and since most of the load for the application we wanted to build would be on the client-side rather than the service side. We decided to see if we could combine a Spring Application with a React app and serve up a single war file.
Every programmer who is buying a new computer will ask themselves, ‘Should I buy a desktop or a laptop for coding’? Also, what computer should I buy if I also want to do other things besides coding, like playing games?
This guide explains how to use React and Redux to fetch data from JSON files in an easy and lightweight method through a real example and well explained steps.
For Java developers, last, a couple of years has brought plentiful changes and posed a tough challenge with keeping up-to-date with new Java version every 6 months, and many release of popular frameworks like Spring 5, Spring Security 5, and Spring Boot 2 etc.
Everyone, well, almost everyone, loves video games. So even if you are not going to be a professional game developer or just don’t know for sure, to learn a programming language through practice and creating your own video game project is an excellent idea. Furthermore, it could be a good motivation for your learning.
Web apps that contain tables, charts, and graphs often include an option to export the data as a PDF. Have you ever wondered, as a user, what's going on under the hood when you click that button?
Many people, especially beginners, think that developing a website is purely about coding, but it’s not like that. There a lot of other things that you need to do if you wanna create at least a decent website. The part when you actually make a website with code or with WordPress or some other CMS is just a small part.
There’s a common misconception in software development that you have to spend hours at the office, chained to a PC and coding books to learn a new programming language. The good news is, with the impressive development of mobile coding education, you can learn on your feet and combine professional development with running personal errands.
I wrote a post recently describing how I distributed malicious code that gathers credit card numbers and passwords from thousands of sites in a way that’s quite difficult to detect.
The software development industry is flourishing, and the best part is it pays off well! There has been always the demand for good and qualified software developers and that is the reason why more and more people are learning codes as it is the most appealing career option. However, with the new skills, technologies, and programming languages coming up in the industry, developers are finding it difficult to understand the ways to start.
Python and JavaScript are the two hottest programming languages today. However, they cannot remain on top forever. Eventually, they must fall out of favour, as all languages do. This is likely to happen within the next decade or so.
Hi everyone! There is a lot of information about different C# features. About various life hacks and best practices in this language.
I want to tell you about equally useful, but less popular tips for working with this language.
Docker, Maven, and Jenkins are some of the most popular tools in the DevOps and Java world. Maven helps to organize your project and provide support to build and deploy Java projects while Jenkins can provide continuous integration and delivery by completely automating build and deploy projects.
After hitting a certain level of experience & spending quite enough time in the industry, I have realised the importance of designing/architecting system & software. So I have started looking into system/software design & got to know nothing can better start than a Design Pattern. And the first thing I have done is googling "What is Design Pattern?" Hence got the idea of this article.
Since the early days of Unix, the shell has been part of the user's interface with the operating system. The first Unix shell (the Thompson shell) had very limited features, mainly I/O redirection and command pipelines. Later shells expanded on that early shell and added more and more capabilities, which gave us powerful features that include word expansion, history substitution, loops and conditional expressions, among many others.
react-cool-img is a lightweight but powerful React.js image component, which helps you handle image UX (user experience) and performance as a professional guy 🤓. It empowers the standard img tag by many cool features without breaking your original development experience. Ideally, it can be an img tag replacement for your React.js project.
If you ask any software developer, there’s a decent chance that they have tried their hand at game development. It seems like a natural fit since it uses many of the same skills. What’s more, programmers come into it with the knowledge that most aspiring game makers lack: how to write good code and create effective software.
On my self-taught programming journey, my interests lie within machine learning (ML) and artificial intelligence (AI), and the language I’ve chosen to master is Python.

New to Python? Or are you already a seasoned developer looking to boost and advance your Python knowledge? We have compiled a bull-pack of recommended resources for anyone looking to learn Python Programming. We have tailored these resources to be suitable for Python developers of all levels but the resources listed will be most-applicable to those still early on the learning curve or already familiar with the basics but not really advanced.
Go is a programming language often used for applications in which performance matters. Optimizing your code based on assumptions is not a best practice of course. You need to have insights about your code performance and bottlenecks to be able to optimize it efficiently.
Webhooks run a large portion of the "magic" that happens between applications. They are sometimes called reverse APIs, callbacks, and even notifications. Many services, such as SendGrid, Stripe, Slack, and GitHub use events to send webhooks as part of their API. This allows your application to listen for events and perform actions when they happen.
Javascript is introducing a few new array methods which let us simultaneously copy an array, rather than changing the original. Let's look at how they work.
Building a from-scratch server or using a lightweight framework is empowering. With that power comes responsibility, specifically the responsibility to securely store user’s passwords.
If you’re new to coding, you’ll be pleased to hear that there are a ton of great resources on the web to help brand new programmers learn programming from scratch. In fact, some of the best programmers in the industry are autodidacts with no formal degree in computer science.
I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.
In software engineering, Creational Design Patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic or ordinary form of object creation could result in design problems or added complexity to the design. Builder Design Pattern in C++ solves this specific problem by separating the construction of a complex object from its representation.
In contemporary times, 126,424 websites are made using the python programming language. Many top-notch companies have developed successful apps by using it. This is why it is considered the language of today and the future.
Hello guys , in this blog post I have organized 40 Python projects that you might be interested trying out ranging from webscraping to to natural language processing.
The idea behind creating a quick response (QR) code generator is to translate data from images to text. A QR code is simply the representation of image data as text, and it has a lot of useful applications from restaurant menus and concert tickets, to online calendar invites, payments, and the list goes on.

Hello guys, I have awesome news to share with you. Pluralsight has announced that all their 7000+ expert-led courses are free for one-month, April 2020, to support people staying at home due to COVID-19.
Ballerina is the latest programming language released 1.0 version on September 10th of this year. There are more than a thousand programming languages out there. Why do you need another programming language? Ballerina language intended to simplify the particular programming domain known as integration. You may be a developer who develops different kinds of web services and intends to interconnect those services. Then the Ballerina language could be your next programming companion.
Whether you're making API calls from Node.js or in the browser, connection failures are going to happen eventually. Some request errors are valid. Maybe the endpoint was wrong or the client sent the wrong data. Other times you can be sure that the error is the result of a problem with the connection to the server or one of the many hops in-between. While API and web service monitoring can inform you about the problem, a more active solution can take care of it for you.
If you're trying to learn CSS Flexbox, I bet you've spent some time watching a few tutorials on YouTube. Maybe you've seen the Wes Bos series, that’s a great one. Maybe you're bi-lingual and found some helpful content in your native tongue. Most technical content on the internet is in English, as we know. Yet, sometimes I find some amazing content in my native Portuguese. (Like this remarkably simple to understand tutorial on Flexbox). Finally, how can you not have resorted to the Interneting Is Hard tutorials?
ReactJS is a fantastic frontend framework, and Django is a fantastic backend framework. However, as usual when dealing with anything of more than trivial complexity, it isn’t easy to get the two to place nicely together. It's not like taping a banana to a wall.
I have read somewhere that a programmer should learn a new programming language every year ( I think it's code complete, not sure, though), but if you cannot do so, I suggest to at least learn following five programming language to do well in your career.
We all have struggled with keeping our CSS classes ordered, maintainable, and more specific. SASS nesting and the BEM (Block - Element - Modifier) structure will help get us to get rid of this concern.
With the shift to Cloud-first and the rise of managed infrastructure and orchestrations such as EWS, Azure AKS or GCP clusters the application landscape needs to prepare and adjust itself to match newly rising requirements. This is for such nothing new nor unknown, but acknowledging this fact is one and probably the first important step.
In this tutorial we will see how you can make your first REST API for Machine Learning Model using FLASK. We will start by creating machine learning model. Then we will see step-by-step procedure to create API using Flask and test it using Postman.
With this article, we begin a series of publications about Vue.js technology and try to make out the application development and all its components from different practical sides. In this part, we will tell you what the Vuex library is and analyze in detail such components as a store, state, getters, mutations, and actions.
The craze for learning programming languages is very high. These days people have one question in their mind and that is which programming language should one prefer in 20201 and why?
Anyone who’s wanted to learn coding knows that it’s anything but straight-forward. You’ll face hardships and unexpected roadblocks along the way. You’ve faced them, I’ve faced them.
Despite the popularity of currying and the rise of functional programming (and of TypeScript), it is still a hassle today to make use of curry and have proper type checks. Even famous libraries like Ramda do not provide generic types for their curry implementations (but we will).
One of the hardest things a developer must do is release their bug-riddled code out into the world, knowing they may never hear from those little critters ever again.
Sometimes a short thought can bring amazing ideas. There are some great quotes I’ve been collecting. I use them as inspiration or motto for some articles.
Hello guys, if you are thinking about how to become a Blockchain Developer in 2020 and looking for some online courses to startwith then you have come to the right palce.
It’s not like there aren’t enough text editors. But consider this: with about 60 lines of code (that’s close to nothing), you can make your own secure and stable text editor. It will be pretty simple and won’t have many features, but it will be of your making, even if you barely know how to code.
Learning to code can be tons of fun but it is often overwhelming. Web developers, especially new ones, are constantly learning new content. What makes it worse is that there are so many rules to learning how to write good code.
When I began learning JavaScript, I made a list of every time-saving trick that I found in other people’s code, on code challenge websites, and anywhere other than the tutorials I was using.
This article is really a precursor to cool things you can do with calculus such as the persuit curve which is used in air-to-air missiles, and rocket launch equations.
Full-stack development has been in the limelight in recent years. There has been a lot of talks surrounding the future scope of full-stack developers and how this position could change the business game for companies all across the globe. The rising demand for seamless technology has enabled developers to work on both back-end, front-end and many other related fields.
Creating a Python Virtual environment will allow you to work on an isolated copy of Python for specific projects without interfering or impacting the working of other ongoing projects.
In software engineering, Creational Design Patterns deal with object creation mechanisms, i.e. try to create objects in a manner suitable to the situation. In addition to this basic or ordinary form of object creation could result in design problems or added complexity to the design.
These days, machine learning and computer vision are all the craze. We’ve all seen the news about self-driving cars and facial recognition and probably imagined how cool it’d be to build our own computer vision models. However, it’s not always easy to break into the field, especially without a strong math background. Libraries like PyTorch and TensorFlow can be tedious to learn if all you want to do is experiment with something small.
I should say at the outset that there’s no real point to this blog post. I had a thing to do, I did the thing, and was moderately pleased with the result. I enjoy reading of such tales from other developers, so I thought I’d share my story.
If you are a computer science graduate or a programmer who wants to learn Java and looking for some awesome resources like books, tutorials, and online courses then you have come to the right place.
A full stack developer is an engineer who can handle all the work of databases, servers, systems engineering, and clients.
The process of preparing for coding interviews is anxiety-inducing for many developers. There’s so much material to cover, and often much of it feels irrelevant to what devs are doing in their day jobs, which only adds to the stress.
A professional-looking site is all about the details: the colors, the graphics, the subtle elements, and the overall look and feel. In this project, I’ll show you how to make beautiful, elegant, and professional-looking links that can help your website stand out.
How to become a Python Programmer in 2020?
If you ask any software developer, there’s a decent chance that they have tried their hand at game development. It seems like a natural fit since it uses many of the same skills. What’s more, programmers come into it with the knowledge that most aspiring game makers lack: how to write good code and create effective software.
