[2:01:11][Q&A][:speech]
[2:02:39][@thebirkisreal][Q: Haven't done much on dumpview lately as it's pending a rewrite in ~Odin. But I did just get to use dumpview for the first time today. Here is some usage code.[ref
site=Pastebin
url=https://pastebin.com/DdYM4M4D] And for those asking this is not Jai, it's ~Odin]
[2:02:53][@davechat][Q: Could you make an elevator in the game?]
[2:03:24][@iwrestledabeer][Q: Hey [@cmuratori Casey]! Off-topic: Is it beneficial performance-wise to use switch statements instead of if-else blocks? As far as I could understand from disassembly, using switch statement allows to compute where to jump to directly, without invoking the cmp instruction for each case. Is that correct?][:language :performance]
[2:05:00][@genericfeller][Off-topic, but I watched your 30 Million Lines of Code,[ref
site="Handmade Miscellany"
page="The Thirty-Million Line Problem"
url=https://guide.handmadehero.org/misc/30mlocp/] and was wondering whether you think that Intel and other hardware manufacturers would be more likely to adopt an :ISA as a response to consumer-unfriendly policies from Microsoft (if they're scared of consumer PC markets collapsing)?]
[2:08:30][@wheeel][Q: Are all rooms going to be procedurally generated or are they gonna be hand-cranked and then just populated with certain entities procedurally?][:"procedural generation"]
[2:08:34][@gaius_is_best_colossus][Q: Have you played any of the Souls games? What do you think of them? (I don't know if I asked this question before)]
[2:08:50][@thecrypticmind][Is the game going to contain both 2D and 3D assets? Or are the cubes only for testing purposes?]
[2:09:24][@pythno][Q: Regarding Intel shipping their own "platform that just runs": How would that look? Would there be a minimalistic OS boot up once you power on the machine? Sorry, if this is obvious but I don't quite get it]
[2:12:38][@thegeekpirate][Q: Favourite cheese?]
[2:13:06][@aidsjorb][Q: Any more office moving drama / insanity to share? Has the reason for the move been talked about?]
[2:13:48][Wrap it up][:speech]
