In this blog post I intent to give a brief overview of “Daj się poznać” competition and some reasoning why I decided to join it. Few words about ”Daj Się Poznać” “Daj się poznać” (in English: “Let yourself known”) is a competition aimed at Polish programming community and it’s idea is to help programmers to be more involved in both blogging and open source work. Currently it’s aimed only at the polish market, so all content on the official website is in Polish, most of the participants are blogging in Polish, only few in English.

As an alternative to flux I use redshift on my Linux machine. Recently I stumbled upon very weird problem – each time I close Java desktop app and redshift was active, the screen flashed. It was a very quick change that looked like redshift was disabled and then enabled again. I was starting redshift like this: redshift-gtk -l manual -l 51.126:17.033 After trying out few configuration options it turns out that changing video method to vidmode was the right solution for my problem:
