We, the PVS-Studio static code analyzer developers, have a peculiar view on beauty. On the beauty of bugs. We like to find grace in errors, examine them, try to guess how they appeared. Today we have an interesting case when the concepts of length and size got mixed up in the code.
This article continues a series of notes about colorization. During today's experiment, we’ll be comparing a recent neural network with the good old Deoldify to gauge the rate at which the future is approaching.
This is a practical project, so we won’t pay extra attention to the underlying philosophy of the Transformer architecture. Besides, any attempt to explain the principles of its operation to a wide public in hand waving terms would become misguiding.
A lecturer: Mr. Petrov! How does a transformer work?
Petrov with a bass voice: Hum-m-m-m.
Google Colorizing Transformer vs Deoldify
C# has low barriers to entry and forgives a lot. Seriously, you may not understand how things work under the hood but still write code and remain easy-going about this. Though you still have to deal with different nuances over time. Today, we'll look at one of such subtle aspects — handling enumerations.
As a side hustle, I teach tech recruiters web and software development technologies using plain English. It helps them with understanding job specs and resumes and it makes all of us, tech people, happier.
I run a weekly newsletter and often get feedback from recruiters via email or LinkedIn DMs.
I thought that I could try to collect feedback using the “Reactions” feature just like LinkedIn or Facebook does. It’s not as informative as personalised messages but is a simple feature that may incentivize more people to provide some general feedback.
Either way, it’s worth trying and as a software developer, I can’t wait to implement it.
This tutorial is about implementing a feature that will be used in real life on my project.
In this article we will once again return to the tired topic of webinars and webinar hosting tools. And no, we're not about to code a whole new system for webinar hosting – there are already plenty of those. Instead, we will talk about connecting drawing software to the webinar, so that you could manually draw and broadcast the process.
Getting acquainted with the CodeIgniter 4 PHP framework is quite simple.
Spend the evening following the instructions in the «Build Your First Application» section. Since the documentation is written in a good, technically understandable language, it is even possible to get some aesthetic pleasure in the process of familiarizing yourself with this and other sections.
The feeling of airiness and consistency of the CodeIgniter 4 project will be present with you everywhere now.
What is so attractive about CodeIgniter 4?
Goal: continuously send UDP packets from an Arduino Nano 33 IoT to a Raspberry Pi 4 to understand the reliability of this solution.
We present a guide to name entities in code based on putting naming in perspectives of semantic space, design, and readability.
The main idea is that naming should not be considered as creation of tags, but as a fundamental part of design process, which implies integral and consistent vocabulary to be used. We discuss naming process and naming formalism from these perspectives and we provide guidelines for practical use.
The work is based on 15 years of experience in engineering work, coding and development management in high-tech industries.
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.

Measuring of stream rate in an artist's impression.
In one of our previous publications, we talked about a way to measure event stream rate using a counter based on exponential decay. It turns out that the idea of such a counter has an interesting generalization. This paper by Artem Shvorin and Dmitry Kamaldinov, Qrator Labs, reveals it.
One Day in the Life of PVS-Studio Developer, or How I Debugged Diagnostic That Surpassed Three Programmers
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.
Network architecture at hyperscalers is a subject to constant innovation and is ever evolving to meet the demand. Network operators are constantly experimenting with solutions and finding new ways to keep it reliable and cost effective. Hyperscalers are periodically publishing their findings and innovations in a variety of scientific and technical groups.
The purpose of this article is to summarize the information about how hyperscalers design and manage networks. The goal here is to help connecting the dots, dissect and digest the data from a variety of sources including my personal experience working with hyperscalers.

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.
