PVS-Studio has a mascot that became inseparable from the brand - a unicorn. Lately we've been getting many questions about our magic steed: why the unicorn, why has he changed so much, does he have hooves, how come he doesn't wear pants, and how do we draw him. The answers are finally here, in this very article.
Attention: there will be a lot of pictures. And I mean A LOT.

It will deliver huge business benefits for them and has the potential to increase business income and profitability.
The "Click to Call" button on the website is an "innovation" that has been around for about 10 years. The technologies under the hood have changed, but the principle remains the same: someone clicks on the button on the site page, then JavaScript launches and requests access to the microphone and establishes a connection to the server — WebRTC SIP gateway. Further, the first client-server leg is a browser gateway, the second leg can be arbitrarily long and through the SIP proxy chain can eventually connect to a mobile or landline phone. Thus, the browser turns, in a sense, into a softphone and becomes a full participant in VoIP telephony.
Static analyzers' primary aim is to search for errors missed by developers. Recently, the PVS-Studio team again found an interesting example proving the power of static analysis.
Four months of awesome work together with a few new contributors finally result in a new major release, which I'm happy to announce about.
Now we get completely new matrices, improved parser, a lot of new functions, almost rewritten interactive package (for working in Jupyter) and many more.
This article about a big update in a FOSS symbolic algebra library for .NET, I hope it may be interesting for someone!
When creating a .NET library with a partially platform-specific API, we should think about how to pack it into a NuGet package so that the installed library will work in various scenarios (.NET Framework, .NET Core, self-contained application and so on). Unfortunately, it is difficult to find a step-by-step instruction on the web that describes how to perform this task. This article is intended to be such an instruction.

Microservices Architecture is a well-known pattern for building a complex system that consists of loosely coupled modules. It provides better scalability, and it is easier to develop a system in multiple teams so that they don’t interfere with each other too much. However, it is important to choose the right way of communication between the services. Otherwise, this kind of architecture can do more harm than good.
Visual Studio from Microsoft has long been the main development environment to work with the PVS-Studio analyzer. Our analyzer started off on Windows, so Visual Studio was an obvious and reasonable choice. In more than 10 years of PVS-Studio development, the analyzer has become available for several other languages and platforms. No wonder people ask us if we can integrate PVS-Studio into their favorite IDEs.
When a company decides to build a marketplace, one of the most critical issues to solve is building interaction between all operational processes.
You need a system where you can manage and exchange customer, partner, and order data. Often the back-office of a marketplace consists of a complex of systems. However, we have been working with marketplaces for many years and have come to the conclusion that the integration between back-office systems should be seamless. At least between 6 fundamental parts. Thus, we have created the Scallium platform, where the business manages the processes of the marketplace.
The popularity of online education is increasing every month. And since there is an increase in popularity, there is an increase in competition and an improvement in quality: many authors of online schools realized that nowadays it's not enough to just make something mediocre using the frontal camera of the iPhone 4. You need to work on the quality of the picture, sound, presentation of material, etc. Not only did the pandemic prove that you can teach salsa and even crochet online, so it also gave an excellent push to improve the materials taught + diversity in the labor market. Moms on maternity leave can rejoice - now you can truly earn a hundred thousand million per second, sitting at home.
During the lockdown, which is now weakening, then becoming more active with a vengeance, a huge number of new professions have appeared. Proficients in creating involving Instagram Stories, course producers, e-learning specialists and other unknown-before-creatures - all of them have mastered a new job that gave them the holy bread in the pandemic. Once you hire a creator of involving Instagram Stories (and let's all hope this person was teached by a professional, not a snake oil salesman), your business grows just with adding some creativity in advertising that will take the heart of even the most fastidious customer. Same works with e-learning specialists: you recruit them and they do all the important tasks from writing articles that will also help in promoting your classes to arranging lessons on your Coursera course. A complete flight of imagination: if it seems to you that some jobs don't exist, then you just don't spend enough time online. In general, online work has become popularized as never and now hardly anyone will say: "He is engaged in some kind of garbage - he makes TikToks but it would be better for him to toil at the factory!". In total, online work has become popularized as never and now hardly anyone will say: "He is engaged in some kind of garbage - he makes TikToks, but it would be better for him to toil at the factory!".

Hackathons could be very intimidating and stressful. The key to getting better is doing simple projects. In this article, we will look at an example of a web app that can be used for sharpening your skills when you prepare for a hackathon. We will use a powerful Google API based on Machine Learning and apply the following technologies: ASP.NET, HTML, Docker, Heroku, and Git.
One of the main challenges in the world of web development is to achieve a seamless user experience. Many factors come into play when trying to achieve the goal of a smooth UX. The user interface, the load-time of webpages, and updating any data/input sent, are some prominent examples.
All web development frameworks offer tools that enable the developer to make the UX as smooth as possible. After all, it’s an important aspect of a website. In the case of the popular front-end framework Angular, such a tool is the RxJS library.
Through RxJS, Angular applications can employ the reactive programming and functional programming paradigms to ensure a smoothly working inside-out. This article acts as a quick guide to RxJS and how it is used in Angular applications. It will discuss some of its robust features and give you their flavor through code examples. Using RxJS to speed up and improve an Angular application’s UX is common practice and this article will show you why.
What Does RxJS Do Exactly?
In the everyday workings of a website, it handles different requests and events. Requests like inputting/outputting certain data or transforming some data, and events like responding to a mouse click or keyboard key press. If all of the requests and events are coming in one after another (synchronously), they are responded to in that order. However, few frameworks can respond quickly and reactively in the case of asynchronous requests and events.
RxJS is a JavaScript library of functions that allow to smoothly handle asynchronous events and requests. The name comes from the fact that it enables reactive programming in JavaScript. It allows for playing with and tracking time in your Angular application. The amount of time between responses or events can be fine-tuned as required through RxJS, letting the developer control the responsiveness of the application.

In my previous post, I touched on the point that Redis is more than just an in-memory cache.
Most people do not even consider Redis as a primary database. There are a lot of use cases where Redis is a perfect choice for non-cache related tasks.
In this article, I will demonstrate how I built a fully functional Q&A board for asking and upvoting the most interesting questions. Redis will be used as a primary database.
I will use Gatsby (React), Netlify serverless functions and Upstash Serverless Redis.
Upstash has been a good choice so far and I decided to try it out in a more serious project. I love everything serverless and how it makes things simpler for me.
Serverless will be a great choice for most tasks however you need to know the pros and cons of the tech you are using. I encourage you to learn more about serverless to get the most out of it.
The software development world is a dynamic one. Tools and applications are constantly upgrading and getting better to make advanced technology possible. Technologies that do not upgrade will eventually become obsolete and fade away with time. The principle of constant upgrading is especially true for the really popular tools, like the front-end framework Angular. To provide developers with a more robust and solid front-end development experience, Angular introduced a cutting-edge compilation and rendering pipeline in their version 9. The new engine was christened Ivy.
With Ivy, Angular aimed to double down on the advantages it traditionally offered. This article will take you through all the new advancements that come bundled with Ivy. It will also quickly go through what is deprecated and how it handles Angular applications made on the previous View engine. Angular Ivy was made to accommodate all exciting new developments that could be needed in the future. This article talks about the updates that followed the original rollout.
What’s New In Angular Ivy
Ivy was introduced as the default engine with Angular’s version 9 and continues to support subsequent versions. One of the main aims of Angular’s Ivy engine was to amplify the performance and minimize the file size of Angular applications. The development team behind Angular employed different techniques to achieve the aim of faster and lighter Angular applications. The prominent strategies behind Ivy are discussed below:
