[0:39][handmade.prj: Move the .prj files from the code to the root directory]
[1:11][Recap and set the stage for the day]
[2:38][Run the game, do a hot-reload and note that the profile is busted]
[3:48][Explain the debug collation situation in terms of multithreadedness]
[8:45][Consider how to potentially solve the problem]
[12:19][win32_handmade.cpp: Flush all the queues, do FrameEnd and then finally do the hot-reload]
[14:58][Run the game, attempt to hot-reload, and hang]
[15:54][Debugger: Investigate what's going on here]
[17:52][Explain the bug: Upon hot-reloading, we go back through the collation code because there was no collation code to call]
[19:07][win32_handmade.cpp: Try loading the game code multiple times during collation]
[21:43][Run the game and try hot-reloading]
[22:21]["How about you actually check to see if it's loaded, Muratori!"][quote 440]
[22:34][win32_handmade.cpp: Fix the LoadTry loop]
[23:03][Run the game and try that one more time]
[23:32][Debugger: Investigate what's going on]
[24:45][Blame it on the code][quote 441]
[26:21][handmade_cutscene.h: Introduce struct cutscene and enum cutscene_id]
[29:26][Run the game and find that we're not safe across reloads in the cutscene mode]
[30:29][Debugger: Break on Win32UnloadGameCode and inspect the GlobalDebugTable]
[34:00][A thought][quote 442]
[34:24][win32_handmade.cpp: Disable the EventRecording while we reload]
[39:18][win32_handmade.cpp: Enable the EventRecording initially]
[39:51][Run the game and...]
[40:23][Admire the lovely profiler][quote 443]
[40:55][build.bat: Switch to -O2 and see how the profiler fares]
[41:56][Happy puppy][quote 445]
[42:03][Q&A][:speech]
[42:40][@erafo][Not sure if this was asked before but is it worth to use static_cast instead of a C-style cast that does static_cast, dynamic_cast and reinterpret_cast, if you know that you only need the first?]
[43:32][Demo: C-style cast]
[48:19][Demo: C++ dynamic_cast]
[51:29][@cubercaleb][How exactly did they mess up casting in C++?]
[53:21][@novynn][dynamic_cast will return 0 if it fails]
[53:39][@evraire][Is the debug view for bitmaps working again?]
[54:15][@rooster441][For string manipulation, is there a library worth to use in C/C++? I could do it with Python but I'd like to use C]
[54:57][@deepmist][You are spending a lot of time on debug tools before you need them. Is it going to be worth it?]
[58:07][@cubercaleb][Speaking of string libraries, what kinds of things do you think should be in a good string library?]
[59:36][@insobot][@expixel: Hand banana hero. You rock]
[59:40][Andrew Chronister: "Insobot is a national treasure"][quote 444]
[1:00:01][@cubercaleb][Does using VirtualAlloc and reserving a lot of memory upfront count?]
[1:01:16][@cubercaleb][Well I meant using MEM_RESERVE then MEM_COMMIT so that you can append quickly without the copy]
[1:01:40][Go eat dinner][:speech]
