I made a small program to factor trinomials (form ax^2+bx+c) because I had a ton of homework about it. The program lets you input the first coefficient (a), the second coefficient (b) and the constant (c). It then gives you the two middle terms to factor as well as the final factored answer.
I gave a crack at making a Mari0 Online MP mod, I personally think it works pretty well. It uses the MagicDNS system made by Stabyourself so joining games is super easy. You get two simple words and that allows others to join your match using those words. There's no UDP puncholing unfortunately though, so you need to port forward. If you need a match to make, try the Stabyourself steam group, there's usually people in there willing to play.
