1:20:46amethystr3lm handmade_hero As someone who started the series a few days ago and wants to make a game of his own, how do I manage to catch up with the current stage of the game? And should I even care to do that? It's true that I should always pay extra attention where I think I need to, but I don't know what's coming within the 600 episodes and whether spending extra time on things that I thought needed the extra time will be worth it or not as opposed to getting a conceptual idea on the subject and move on

1:23:49ceburger handmade_hero I recently discovered your stream (so forgive me if you have covered this before). I learn a lot from the in-depth videos on how a computer actually works on a fundamental level, like the C tutorial and the blackboard videos (and I have been programming for 10 years). I am really excited about Star Code Galaxy. Do you have any information about when it will launch and what kind of material it will it cover?³

1:33:10centhusiast Q: My friend started working as a C++ programmer and he showed the codebase he has to work with and it was a jungle of classes, template, std:: and it was very slow to compile. Is it a common thing in the industry to have this kind of code base? I guess that is why software are of bad quality

1:39:25ceburger Q: I use some templates in my C++ code, to avoid large amounts of code duplication, but I struggle with compile times.
