It’s a fork bomb. Specifically it’s a piece of code that recursively calls itself and then it calls itself to run the code.
Thank goodness it did not work, but please do not actually run code like this!! Do your best to figure out what the code is doing before you attempt to run it!





Thank CHRIST. It was a badly needed feature, especially if Valve wanted me to use their Steam Client over everything else (I’d be happy to add external games to Steam, but not seeing the nice artwork really ruin things)
