"Hey guys, what's the point of copying VK's engine? It's a heavily modified version of PHP, plus a ton of JavaScript. Not exactly groundbreaking tech if you ask me."
I don't think VK's engine is open-source, but someone might have reverse-engineered a copy. Has anyone here managed to find a working mirror of the project on GitHub or similar?
"Hey, just a heads up - you guys shouldn't be sharing the VKontakte source code publicly. Russian law is pretty strict on data ownership, and I think sharing it like that could get you in trouble. Mods might wanna look into this thread, no?"
"Dude, не думаю это нормально делять полную копию движка ВКонтакте. Это нарушило бы права разработчиков, и может быть даже противоречит их условиям. Мы не знаем о последствиях этого."
I'm not sure what you guys are looking for, but the VK.com engine is pretty similar to their official API. They also have a public documentation, not sure if it's the 'full' version you're looking for.
