[1:59:18][@nordicplayer][Q: I'm creating an OpenGL engine in C#. I really enjoy the language and I'm enjoying the process, but should I just go move to C++?][:language]
[2:01:00][@guybru5h_vi][Q: What's your learning method when faced with a new topic? How do you juggle figuring things out yourself vs reading a textbook. My problem is wanting to move quickly but also wanting to learn deeply]
[2:03:40][@theomarest][Q: Do you have an official code style guide anywhere?][:language]
[2:03:56][@alex_deak][Q: Hi from Hungary! I took your advice you gave me last week and started a blog[ref
    site=Variables
    url=https://sandordeak.home.blog/] to get involved in the game industry. It contains a few posts already, and some description of my earlier projects. Maybe worth reading sometime]
[2:08:30][@frostyninja][Q: Hi from Bulgaria (er UK now)! I’m starting an internship in July at a game studio and I’m super excited and I feel I owe you a lot of gratitude for keeping me excited about game dev!]
[2:09:27][@Brian][Q: Greetings [@cmuratori Casey]! You have a distinct coding style and though I realize you may have evolved into it over the years, I was wondering if there was there something specific that directed you? It could even have been you did not like other styles. I know you appreciate good typography too so I wonder if some of your decisions were based on what you like][:language]
[2:12:20][@xxthebigfoxx][Q: You deleted an X]
[2:12:22][Re-fix typo in CreateArtSceneryTagGrid()][:"asset system" :parsing]
[2:12:28][@theomarest][Q: Are u32, f32, etc. aliases or supported by the :language?]
[2:12:59][Thank [@x13pixels George] for fixing our reported ~remedybg bugs][:speech]
[2:15:17][@alexkelbo][Q: When porting to other platforms, do you have to rewrite all your shaders in HLSL and Metal SL? Is there a way to transpile GLSL?][:language]
