Security & crypto resources
I have been participating in root-me CTFs and war games. Root Me is a platform for everyone to test and improve knowledge in computer security and hacking, and I would definitely recommend checking it out. I have also been working my way through CryptoPals challenges. You can find my solutions here.

Numerai is Kaggle-like competition on encrypted data. During the first year of it's launch I tinkered with a few models that were moderately successful. Although the competition
has probably progressed since then I am making available some of the code I used here.
