Even though this seems to be a niche community and following, I must say that having been in the software world professionally now for a few years, Casey is one of the smartest, most respectable, and most hardworking programmers I've ever had the pleasure of "meeting." The fact that the show still exists after FOUR YEARS says perhaps even more than all of the great lessons learned by watching it. I think this in and of itself goes understated in the community - so many codebases on GitHub are started and abandoned in a matter of months - let alone years.
I thank myself all the time for having learned so many core computer science fundamentals from Casey - and many folks I work with have been impressed by my knowledge which is directly attributable to this show.
But most importantly, Casey has amazing work ethic that is almost completely unheard of now adays. I've never developed a video game and probably never will - but the videos on multithreading, CPU architecture, and compiler stuff are priceless and relevant to the line of work that I'm in as well.
I want to extend a HUGE thank-you to Casey Muratori for having such a positive influence on me as a programmer and also on my career. In a sea of mediocre, Casey's skills, dedication, and teaching ability stand out like a sore-thumb. Casey may appear dogmatic at times but a dose of dogmatism instead of conforming to bullshit practices because "that's the new thing everyone is doing" is extremely important to producing a quality product. In this regard, Casey has inadvertently been a (very, very high quality) mentor to me. It's a shame HandmadeCon is no longer happening because I'd love to meet the man in person!
