I forgot to post after yesterday's stream, but I mostly went over bugs I fixed to get edge rendering working, and then drew diagrams of sweep line triangulation edge crossing cases. I realized that I missed a case, too! We raided @lunazera.bsky.social , who's doing her first donothon! 💜🐺

Now that I finally have edge rendering working, it's hopefully easier to see why it'll be useful for debugging my polygon triangulation code, along with a bunch of other things. Now, I just need to add position numbers and triangle numbers, to keep track of what's what 🖥️😺

The past few weeks should be a wakeup call to all researchers: OpenAI will unashamedly go out of their way to plagiarize your work, attribute the work to A.I., and threaten your career when you catch them, just like they've been doing to artists, writers, and musicians this whole time. #NavierStokes

Rich people threaten to sue those who report on the allegations against them, and unfortunately, many organizations fold instead of standing by their reporters. Thanks so much to People Make Games for taking a stand, and a huge risk, to report on this story. Best of luck! 🙏

Our donothon starts Sept 27th, this Sunday! Just in time to catch the last bit of Subtember :3 I want to incentivize Patreon, so new memberships will get 2x the timer amount on every $1 !! We have a giant wheel of games to get through, and there'll be lots of modelling and things we'll be doing :D
Promotional graphic titled "LZ's First Donothon", featuring art by creamyroux of an anthropomorphic wolf Alice on the left. The subhead reads "To help with savings for bottom surgery eventually!" and at the bottom of the graphic reads "Starts Sept 27th. twitch.tv/AliceLunazera"

In the middle are three bubbled sections of information. The first reads "Streaming almost every day! (with rest days and as time/life allows). Timer Increases: 5min per sub, 2min per 100 bits, 2min per 1$, 2x for Patreon sub"

The second section reads "Extra Goals to unlock! Music streams, art modelling streams, a sleepover...?"

The third and largest section reads "Milestones" and lists out 7 prices from $50 increasing to $2000. The milestones are "Chat writes bsky post, new stream quote-bot, chat decides new emote, bring back leash, win2000 computer stream, new background art commission, make a low poly model". Below this reads "and more..."

Jokes aside, disagreeing with someone or not liking someone doesn't automatically mean they're sexist, racist, homophobic, or transphobic. Calling someone a monster just because you don't like them makes you look bad, and it hurts everyone experiencing prejudice.

Decades ago, "I clocked him" meant "I punched him", a shortening of "I cleaned his clock." Now, "clock" as a verb has a meaning similar to what used to be "peg" as a verb, but if you say "I pegged him as a man of good taste", it means something a bit different now 👀
