SIO2 is Polish Olympiad in Informatics's automatic grader (the insider term, I hear, is “online judge”) for competitive programming contests. If you wanna try it out, I recommend the Olympiad-run public instance for training, Szkopuł.
But SIO2 is not just about submitting code solutions. The internal APIs are abstract enough to support, for example, quiz type contests.
They haven't seen much use over they years, though. But quizzes have always been a heavy part of the Polish Junior High School Olympiad in Informatics, and while the junior high schools are gone now following an (in my opinion) awful education system reform, some of the tradition is to be continued by Polish Junior Olympiad in Informatics, now for primary schools.
My first Spotify playlist dates back to February 2013. It's over 2000 tracks long at this point, and most of my time alone I just put it on shuffle.
At first I was only listening on my desktop and my Android phone. I made use of the free tier for a year, before Spotify realized it had near-zero revenue in Poland and started pushing for Premium subscriptions aggressively by cutting down features.
With MyAnimeList down for days now, I’ve been seeing people turn to other alternatives such as Kitsu and Anilist a fair deal recently, and although I have long since done so, it is a new for at least three of my friends.
But even with Kitsu being a libre alternative to MAL, I’ve been kind of disappointed with how centralized it is, and how if it falls down, it falls down, just like any centralised social network.
EDIT: the demo is no longer available.
You might look at it and think it's completely idiotic and ask why would anybody want this, but I have a Nokia E51 and I constantly run into websites that force HTTPS on everything and my phone doesn't understand either TLS or SNI (can't remember) so the only thing that works for me is Google, not even Wikipedia.
I figured out it's about time to give some of my projects a write up, and I'm pressed by time, so it seems like a perfect opportunity.
A few months ago, as my dear friend and Crystal fanatic RX14 decided to shut down his file hosting of worldwide fame, aww.moe. Most precisely, it wasn't shut down, it was changed to private-only, and while he did offer me an account, I didn't feel like depending on somebody else to host my precious files.
