[1:56:04][Q&A][:speech]
[1:56:51][@jkfsda][Q: Will C++ add CSP type concurrency in the next edition?][:language]
[1:58:35][@ejgremlin][Q: Have you seen Bret Victor's talk Inventing on Principle?]
[1:58:41][@ivereadthesequel][Q: On the pre-stream I'd asked about finding the filter kernels and you asked whether I meant the integer one or the floating point. Do you mind explaining how you found each? Thanks!][:codec :filtering]
[2:00:47][@jkfsda][Q: Have you tried Oni?[ref
site="onivim / oni"
url=https://github.com/onivim/oni/]]
[2:02:15][@philliptrudeau][Q: Don't we want 32-bit floating samples for high quality audio streams? Additionally, are we planning to support surround sound later?][:audio]
[2:04:41][@ormone88][Q: What do you think about procedural :audio? Will we explore something about this during future streams?][:"procedural generation"]
[2:04:50][@ivereadthesequel][Q: Thanks! Also, why was the windowed sinc worse than the one you found, if sincs are ideal? Does the kernel need slight changes from the ideal's values once it is windowed?][:codec :filtering]
[2:05:56][@centhusiast][Q: Is it possible to write a graphics card debugger like NSight, or is it something that has to be done by graphics card vendors?]
[2:07:27][@godgifts][@handmade_hero Hello, I'm a computer science student but recently started following your series on YouTube. They helped me a lot because you explain really good in depth. I just want to say thanks for all the work you do for us and I hope that I never catch up with the series because you will never stop doing them]
[2:08:31][@ivereadthesequel][Q: I'm still wondering why we should choose git over TRAVELMAN? Despite its simplicity, I'm just not convinced it's better][:vcs]
[2:09:24][Add the -diagnostics\:column flag to our cl line in build.bat, for columnar errors]
[2:11:54][@jbcgannon][Q: You made an off-hand comment on a source control tool you made yourself. I take it few have seen it other than yourself?][:vcs]
[2:12:15][@aidsjorb][Q: They intentionally didn't make reporting columns the default behavior in order to not break backwards compatibility]
[2:12:51][@jkfsda][Q: Have you seen V-lang? Is it vaporware?][:language]
[2:13:20][@ivereadthesequel][@handmade_hero Since there are so few questions, can I just comment that your coding style is super pleasing? Just popping out structs left and right, so procedural, no weird modern C++-isms, verbose variable and function names so there's no ambiguity. It's nice and has had a huge influence on my style for the better!][:language]
[2:16:06][@roam00010011][Q: Hit a wall, every company I lookup demands OOP, and not a healthy balance of OO and procedural, but the ultra radical OO and nothing but OO][:language]
[2:16:24][@centhusiast][Q:At work, I started rewriting a python package in C since its performance is so bad that nobody wants it anymore. I was wondering why people do not write in native code that often anymore and choose the scripting languages that causes lots of problems further down the road. Do you have any comment on that?][:language]
[2:18:12][End it there][:speech]
