thomastc | frozenfractalHmm, generating good hashes for use in simplex noise is surprisingly expensive. Has anyone ever tried using the CRC32 instructions that come with SSE4.2 for this? They only take 1 clock cycle, much faster than anything I've come up with. <a href="https://mastodon.gamedev.place/tags/ProcGen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ProcGen</a> <a href="https://mastodon.gamedev.place/tags/assembly" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#assembly</a>

Daniele Verducci 🧉I wrote a very stupid and ugly <a class="hashtag" href="https://social.ichibi.eu/tag/z80" rel="nofollow noopener noreferrer" target="_blank">#z80</a> <a class="hashtag" href="https://social.ichibi.eu/tag/assembly" rel="nofollow noopener noreferrer" target="_blank">#assembly</a> to try it (I'm sure it is filled of errors and I will need a lot of debugging with the <a class="hashtag" href="https://social.ichibi.eu/tag/logicprobe" rel="nofollow noopener noreferrer" target="_blank">#logicprobe</a>), but I could not write it to the <a class="hashtag" href="https://social.ichibi.eu/tag/eeprom" rel="nofollow noopener noreferrer" target="_blank">#EEPROM</a> . The <a class="hashtag" href="https://social.ichibi.eu/tag/minipro" rel="nofollow noopener noreferrer" target="_blank">#minipro</a> errors out while checking the first byte after writing it. That's strange, because I'm using the same programmer and the same eeprom chip as before, and always worked. But in the meanwhile I changed computer, operating system and USB cable, so... troubleshooting time! Yay! 🙄

tyx<a href="https://merveilles.town/@neauoire" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@neauoire</a> I like it so much.If the software development was done in a right way we'd end with the most often used tools which don't have a reason to get new features anymore (text editors, spreadsheets, file managers) rewritten in the most efficient way possible. Like, idk, in C with hot path in assembly (or in Rust for security-critcal parts) with tiny memory footprint on 90% trivial cases, milliseconds to first user input etc. In fact we have exact the opposite - asm in the office apps was absolutely normal in the 90x and I can't imagine anyone doing this nowadays, memory footprint of an empty spreadsheet is 200MB and it takes 5sec. to load with cold cache on a 3Ghz 4 cores with 16G ram with SSD. And the most items in the changelog are about fixing compatibility with some proprietary crap (in FOSS) or adding AI, moving to subscription model or even more telemetry in non-free. <a href="https://lor.sh/tags/assembly" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#assembly</a> <a href="https://lor.sh/tags/foss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#foss</a> <a href="https://lor.sh/tags/spreadsheet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#spreadsheet</a>
