I often have a problem using nginx’s add_header directive, especially with a complex configuration, including multiple virtual hosts. When I test the configuration, everything seems okay, and the nginx does not complain about any syntax. However, when checking the HTTP headers returned by the web server, it looks like it does not work.

Over a year ago, I had done a workshop about the Internet of Things. I had targeted this workshop for programmers working with a different technology stack and with a wide range of skills but with little or no knowledge of electronics and IoT in general. The idea behind this project was to create a small, working example of an IoT device and source code written for both the embedded device and the server-side. During prototyping, we used low-cost, ready-to-use, and easy-to-assemble modules.

The ending of the season one left no doubts - Takeshi Kovacs lives, and we will see more of his adventures in next season. Thirty years after the Bancroft case, another Meth locates Kovacs and offers him a job and a new sleeve. Once again, Takeshi would have a chance to see Quellcrist Falconer. A new sleeve means the new look of the main character, and a different actor is playing the leading role. That important story component allows TV series showrunners to introduce new actors or actresses for the leading role, which has some Doctor Who vibe. Something not so familiar in popular TV series, even those sci-fi.

I was not sure what to expect from the new, second season of Netflix’s Sex Education. At first sight, the series setting looks like a teen series from the 80s and 90s, but in reality, it is likely aiming for adults as a prime audience. The first season was a well-tailored comedy/drama about conflicts, growing up, being an adult, and a parent. Although the primary theme is sex, it is not in any way vulgar or, what would even worse, embarrassing. It was not the best tv series ever but a good one which I enjoyed.

SonarQube is a wonderful tool for static code analysis and code review. Of course, it is not an all in one tool which replaces all other tools used in code review toolchain. SonarQube has a whole section dedicated to code coverage, but it analyzes code coverage, not run any tests.

Creating new docker images based on some official Linux distributions or modifying existing ones increase their size. Sometimes, the difference between the new and the old ones dramatically exceeds the size of new packages or modifications. The reason behind that is mostly the way how images structure looks like and how Docker uses images and containers.
