Advent of Code
Mostly this one will be more of an advertisement than an actual post, but still I would like to write about it.
From the beggining of december, website AdventOfCode.com offers everyday challanges for software developers to do some programming excercises. You write code on your own in any language that you prefer for input provided by this website, and then you have to send them back results. At the moment I do it as an warm-up before starting my work day.
My attempts are mostly written in Ruby (but I take into considerations using other languages on further assignments) and are available in my Github repository. Every user gets his own unique input data, but mine are provided within repository (in case when you want to try it out but website no longer works).
I encourage everyone to try and complete those assignments — who knows, maybe you will learn something new!
