Learn something new every day
Today I learned how to make information find me. Instead of investing time looking for a new framework or where to learn a cool tool – you can sit back and wait for it to come. Similarly to sports- I’d also recommend you to find a small slot every day and learn a small thing,…
Today I learned how to write container images from scratch. When designing a product one must not just think about how to code it, but also how to deploy it. The containerization concept is a good choice in terms of security and also in being easily built and deploy. Building containers from scratch enhance the…
Today I learned what makes an alert to be a good alert. As a developer, we sometimes forget about what happens AFTER we release our code. The monitoring part is an important stage of making the software or product a good and stable one. Based on podcast episode “Alerts (or – Avi was the first…
Today I learned how to strip files. It is kinda doing what you think – removing redundant stuff from the file.

Go was first presented in 2014, pretty new compared to the other popular programming languages like Python (first release in 1991, v3.0 in 2008), C (1972), C++ (1985), and java (1995). The main reason was to create a programming language that will be as easy…
Today I learned how makefiles work. Makefile is a recipe of what commands to run and in what sequence to compile or build your software. Usually, a makefile will look like that: looks scary? let’s go line by line and see what it means: The first line obj_files = foo.c bar.c just statically says that…
The time is mid-2020, not only that we start to have Corinavirous everywhere, I got the 2nd most terrifying news people can get – “You are getting fired!”. This was half a year after moving from a network analyst position to a DevOps position. At first, I knew that this is not the end of…
