I Don't Like Paper Books
New purchase Recently I’ve purchased a paper book. I did it only because I was really eager to read that specific book ( here it is ). The content was good, and I will definitely make a short review afterward, but the process of reading a physical book was quite painful to me. Ooops, here goes the nostalgia I’ve spent quite a lot of time in my childhood and adolescence reading books.…
How to With John Wilson: a must-watch series.
If you’re looking for a way to spend several evenings I have something to recommend to you. There’s an awesome TV-series slash documentary on HBO called How To With John Wilson . The premise is quite simple: the narrator asks the question “How to do X”, for example, “How to make small talk?” and goes to the in-breadth exploration of the topic, meeting various…
Learning music and the guitar as the never-ending failure.

I did not really put a lot of effort into making this project and composed it out of scraps I literally had at home and with the help of tools I already knew and some new things I wanted to try out more in the past. Hardware I have a server rack under my TV with a terabyte of storage, 8-core ARM CPU, a neural processing unit, and the network switch.

Hey there, I’m Andrew. I’m a staff software engineer. Born in Belarus, lived in Ukraine, currently residing in Warsaw, Poland. I write stuff in Python for ~10 years.

Things you may expect reading this blog: reviews of technical books, deep-dives…
Why yet another blog?
Really, why? Hey there. It’s been a long time (as of this moment in Dec. 2023 ~10 years) I’ve been a software developer and throughout these 10 years I’ve been wanting to have my own blog and website. The biggest problem for me was always the thought that there’s nothing for me to write about that can be of interest to the people outside of my life. Everything’s been…
