Learn something new every day
Today I learned how to sell on Amazon. And eBay too! This has been a long journey that started pre-COVID and continues to sell even today. At most, it shows that the one skill you ever need- is to know how to learn. I started with zero knowledge in selling so literally everyone can. In…
Today I learned how to release a new version for dev testing faster. By leveraging external tools, and installing in-cluster components you can enhance your dev cycle, deploy new versions at the speed of light, and, eventually, bring new features in less time. Usually, the development cycle consists of shorter and longer cycles. You start…
Today I learned how to be a valuable team member. The original title was “How not to be a jackass teammate”, but keeping a positive attitude is one of the tips I’ll show. You can call this post the “soft skills guide”. I will take you through a developer’s day and explain how person-to-person communication…

And a little more technical information you might need. As part of developing an actual project, you sometimes need to generate files. You…
Today I learned about monkey patching. Sounds wired, right? I’ll explain what that means. Talk about some use cases with examples in Go. And align with best practices when using this. Bonus- the funniest software license I have ever seen. So as the title spoils, the main topic here is testing. Or more specifically- Unit…

Today I learned about Inter-Process-Communication. Although it sounds trivial to transfer data between different processes. It is actually quite complex.
Today I learned what it takes to host a website. From the Internet – up until your PC. A simple /index.html request needs a lot of components and configuration to be done correctly.
Today I learned how TLS (based on RSA) works. Without entering the core mathematics of cryptography, there are several things you need to know in order to understand how and why common authentication and encryption types work.
