ONLYOFFICE Community Server: how bugs contribute to the emergence of security problems

Server-side network applications rarely get the chance to join the ranks of our reviews of errors found in open source software. This is probably due to their popularity. After all, we try to pay attention to the projects that readers themselves offer us. At the same time, servers often perform very important functions, but their performance and benefits remain invisible to most users. So, by chance, the code of ONLYOFFICE... Read more

Хочу стать программистом: на примере PLM

Такое можно услышать от многих молодых и взрослых людей. Однако, после недолгого гугления выясняется, что понятие «программист» такое же огромное как «доктор». Все сразу и одновременно охватить невозможно, поэтому давайте разберемся в основных направлениях по котором можно развиваться. Если говорить в кратце то программирование это написание программ (ваш кэп). Эти программы нужы для того, чтобы автоматизировать какую-либо деятельность или для развлечения. Например программы управления станками на заводе, а Read more

The Code Analyzer is wrong. Long live the Analyzer

Combining many actions in a single C++ expression is a bad practice, as such code is hard to understand, maintain, and it is easy to make mistakes in it. For example, one can instill a bug by reconciling different actions when evaluating function arguments. We agree with the classic recommendation that code should be simple and clear. Now let's look at an interesting case where the PVS-Studio analyzer is technically... Read more
