[1:03:45][Q&A][:speech]
|
|
[1:04:11][@d7samurai][was this the 'depression oriented programming' approach i keep hearing about?]
|
|
[1:04:32][@m1el][you pass string length together with pointer to string data in several places. Do you think it would be better to create a string struct that holds length and a data point?]
|
|
[1:05:13][@vidster88][You've talked a lot about languages lately, have you taken a look at Swift at all? Thoughts?]
|
|
[1:05:31][@elxenoaizd][How do you come up with that literacy stuff? That was Awesome!]
|
|
[1:05:53][@programgamer][I DONT GET ANYTHING \:(]
|
|
[1:06:12][@yoonfan][do you think that the bug in DebugInteractionsAreEqual would have been caught by a compiler-generated comparison operator as in C++?]
|
|
[1:07:08][@groggeh][will handmadehero2 be written in JAI ?]
|
|
[1:07:16][@elxenoaizd][I meant literature talk sorry lol]
|
|
[1:07:57][@thegeekpirate][Who is your favourite figure in the computing world (dead or alive)? Mine's currently Claude Shannon]
|
|
[1:08:19][@ikkir_isth][how about handmadebrowser in JAI? \:)]
|
|
[1:08:40][@luijee][Off topic but how old were you when you started coding]
|
|
[1:08:47][@a_pulsing_mage][prestream question: do you think that intel hitting the proccesa size limit will make video game falter of will they survive?]
|
|
[1:09:33][@mitch77x][Casey, you are as old as me. Are you also planning to retire from working ASAP ? \:-)]
|
|
[1:10:58][@falsemann][What do you think about Test-Driven Development?]
|
|
[1:11:13][@hecline][do you actually play games yourself? If so what?]

|
[1:11:34][@jayp2][Why should i keep on going in this harsh cold reality, when i get lost on episode 005 of hmh \:(]

[1:12:22]["We just have to have faith that The Variable is looking down on us from The Great Memory, and that if we all just work hard and try to be good people that eventually The Variable will let us into The Great Memory and we'll live in peace and happiness with all of our other discretized values."][quote 326]
|
|
[1:12:57][@actbinary][would you prefer to ui in c code or use something like html or something else?]
|
|
[1:13:08][@ingenero][If you could be given complete control over Microsoft or Apple, which one would you choose and what would be your number one priority?]
|
|
[1:13:48][@brethudson][Mind giving a shout-out about your appearance on the indie(Radio); podcast tomorrow?]
|
|
[1:15:59][@mitch77x][Casey, the question was not entirely meant funny: Can you imagine to still code games and stuff when you are like 60?]
|
|
[1:16:55][@elxenoaizd][sometimes I compare myself with other great programmers and get depressed cause I'm far away from their level - I know I shouldn't be comparing cause they grew up in different environments etc and I know for sure I can reach their level if I apply myself and learn quick, but sometimes it just gets to me and I feel bad about it... have you ever felt that way? any tips how to overcome it?]
|
|
[1:23:10][@gasto5][Do you think Japanese not adopting the OOP paradigm is because they are smarter or simply because of not even being interested in changing to new languages?]
|
|
[1:23:46][@jayp2][Pseudo coder question: How would one go about learning Assembly language? And are compilers/linkers written in that?]
|
|
[1:26:12][@reimaginedgames][would you ever think about using C# or python?]
|
|
[1:26:27][@yoonfan][how do you approach getting an overview of a large code base, like clang or the linux kernel?]
