This post is handling the following situation - how to setup up simple Mysql services with group replication being dockerized. In our case, we’ll take the latest Mysql (version 8.x.x)FYI: all mentioned code (worked and tested manually) located here https://github.com/Wendigooor/mysql_group_replicationI will skip not interested steps like ‘what is Mysql, Docker and why we choose them, etc’.

Lexical analysis is the first stage of a compilation process. It's used for getting a token sequence from source code. It gets an input character sequence and finds out what the token is in the start position, whether it's a language keyword, an identifier, a constant (also called a literal), or, maybe, some error. A lexical analyzer (also known as tokenizer) sends a stream of tokens further, into a parser,... Read more ›

Also, certain key bugs have finally been fixed. (N.B. The “21”... Read more ›

Aspect-oriented programming is a very appealing concept for simplifying your codebase, creating clean code, and minimizing copy-paste errors. Today, in most cases, aspects are implemented at the bytecode level, i.e. after compilation, a certain tool «weave» an additional byte code with the support of the required logic. Our approach (as well as the approach of some other tools) is modifying the source code to implement aspect logic. With introduction of... Read more ›

Недавно на работе получил задачу от руководителя: сделай так чтобы телефон android не сливал данные гуглу. Можете представить мой восторг (и предвкушение) ибо спустя 2 недели тестов я вполне уже чувствовал себя человеком который прошивает телефоны на радиорынке (ничего личного, просто не мой профиль). Прочел отличную статью и понабравшись опыта решил немного дополнить. Статья кстати отличная, рекомендую к прочтению. Давайте рассмотрим несколько альтернативных операционных систем якобы без сервисов гугла, Read more ›

Modern applications are built from third-party libraries like a wall from bricks. Their usage is the only option to complete the project in a reasonable time, spending a sensible budget, so it's a usual practice. However, taking all the bricks indiscriminately may not be such a good idea. If there are several options, it is useful to take time to analyze open libraries in order to choose the best one.Read...

Do the police in the US really shoot black people more often than white people? Is use of lethal force connected with race? How is crime related to race? What are the odds of getting shot by the police if you are white and if you are black? We're taking public data and python with pandas to shed some light on these questions, propaganda and politics set far aside.Read more... Read more ›
