Internet of Things - Let's Build Something!

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. Read more…

Altered Carbon Season 2 - Review

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.

Something not so familiar in popular TV series, even those sci-fi. Read more…

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. Read more…

PHPUnit Code Coverage and SonarQube

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. Read more…

How to Decrease the Size of Docker Images?

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. Read more…
