Static code analysis is one of the most important components of secure software development. It detects errors and potential vulnerabilities early in the development process, when they're cheaper and easier to fix. It also enables developers to detect security issues and flaws that they aren't aware of. This article provides examples to show why static analysis is important, rather than simply speculates on the idea of using analyzers for safety.

Questions: 11Time: 30 min Welcome to Dmitry Sviridkin's quiz inspired by his e-book, "C++ programmer's guide to undefined behavior". If you've read it, you may want to challenge your memory. And if you haven't, you'll find this even more entertaining :)
The task is to guess how 10 cringe code examples may behave. Don't take it too seriously, though. When it comes to undefined behavior, no one can predict how the program will behave—this is why it's undefined.

Get ready for code smells, classic errors, and typos when checking the TDengine project using PVS-Studio. Developers could've prevented many of them if they had carefully designed the code in the first place, kept the logic simple, and avoided macros. Let's break down some of these errors and figure out how refactoring can help eliminate them completely. This time, we'll talk about writing code using the copy-paste method.

Get ready for code smells, classic errors, and typos when checking the TDengine project using PVS-Studio. Much of this is avoidable if we design code carefully from the beginning, keep the logic simple, and stay away from macros. Let's break down some code snippets and find ways to refactor them to leave bugs no room there. In the previous post, we had a good feed of the sausage code. In this article, I'll use a new example to show why macros are dangerous and why I dislike them.

The analysis of the TDengine project code using PVS-Studio reveals classic errors and typos. Developers could've avoided many of them if they had carefully designed the code in the first place, kept the logic simple, and avoided macros. Let's take a look at these errors and figure out how refactoring can help eliminate them completely. Sausage code This meme is the easiest way to illustrate what I mean. Unfortunately, Java programmers aren't the only ones writing "sausage code".

This article begins a trilogy about the Nau Engine game engine. In the first part, we focus on its functionality and explore three categories of common errors: copy-paste errors, logic flaws, and memory issues. What is Nau Engine? Nau Engine is a game engine designed to streamline the development and maintenance of games. Its developers say that their tool should be suitable for any task, any developer, and any platform. 1.
