[2:24:10][@s0imn][Q: What are the flaws of converting a decimal floating point number to a binary equivalent by first :parsing the number, and converting it to a regular integer, ignoring the decimal point. Then using the parsed number as the mantissa, and an accumulated value for the exponent, for the floating point number?]

[2:31:03][@tbodt_][WebAssembly has always had a binary format, which is the default, and a text format to be able to read it][:"file format"]
[2:31:38][@uplinkcoder][@handmade_hero: That's asm.js][:"file format"]
[2:32:09][@somebody_took_my_name][Q: How would you convince a seasoned OO-programmer of the merits of not using it? What is your best statement?][:language]
[2:32:45][wwwwwvwwwwwvwwwwwwwwwwwww Q: Have you ever read any of The Art of Computer Programming?][:language]
[2:33:08][@drealrak][Q: Why you don't use switch in our while(Parsing(Tokenizer)) loop?][:parsing]
[2:34:06][@xxthebigfoxx][Q: Can you explain a bit more of what Windows considers UTF-16? I see it mentioned plenty of times on MSDN but usually it just means wchar_t, not actual utf16 with surrogates]
[2:36:03][@aidsjorb][Q: Has the intentionally deliberate pace for [~hero Handmade Hero] helped you in your day job at all (as say a reminder / refresher), or is it always just tedious to program in this fashion after all these years?]
[2:38:06][@bradsheridanmn][Q: Hey, just saw your talk on "Papers I Love"[ref
site="Casey's Blog"

url=https://caseymuratori.com/blog_0030] or whatever they call it. Super impressed, has brought me back to [~hero Handmade Hero]]
[2:38:48][@ivereadthesequel][Q: If [@naysayer88 Jon] can't come tomorrow, can @Molly at least be here to celebrate episode 512 with a party hat? And cake (not for @Molly)?]
