Must we know a good amount of math to be good at coding? I did code Academy for a time but I got bored and slightly scared off when I found out I need math to be a programmer.
waha just GOLD man! keep it up
https://www.google.com - this is like a fukin gift of the gods, learnin so much searchin so much so much stuff everywhere just everything you need omg
http://www.cplusplus.com - My all-time favorite. Tutorials = 10/10 | Glossary/References = 999/10 | Articles = mostly useful | Forum = like a cheap version of stackoverflow, but still helpful sometimes
https://msdn.microsoft.com - Although not 100% reliable, still the best source of information when it comes to winAPI, afaik. Fits the most basic needs when struggling with windows headers (like the usual "WTF was parameter #7451 of this ridiculous function expecting again?!")
hackforums dot net - Yeah nail me on the cross, but one or two, maybe three decent tuts or source codes can actually be found there. But make sure to ignore the rest of its content (99%) and to NEVER download or buy anything from this site
http://www.highscore.de - Only for our german fellas, this page could help me where others failed, sometimes. And the boost-c++ section is very worth mentioning, imho
https://leakforums.org - Provides some interesting source codes for research and improving your own skills
....
there are plenty of others I just don't remember right now. Maybe I'll update the list later on
EDIT:
http://aluigi.altervista.org/ - Legendary. Back in the days when I was skiddin around and felt leet by crashing quake servers with infoboom, this guy was a god to me- and he actually is HQ as fuck. His page provides tons of professionally written Proof-of-Concepts that cover a wide range of topics (not only online games) and each one is completely open source. This treasure chest is certainly worth a look!
