Optimizing the Marginalia Search index code. The new code is at least twice as fast in benchmarks, but I can't run it in production because it turns out when you do it's four times as slow as what came before it for the queries that are the simplest and fastest to the point where queries exceed their timeout values by a lot. I'm 97% certain this is because the faster code leads to more page thrashing in the mmap-base…

#452My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…
People who think we can reengineer and shape ecology by eliminating key species are here on the dunning Kruger curve.
Better option, if you really want to fight malaria go fight that directly, leave mosquitoes out of it.

#456The current app is being rebuilt as it sucks and the device is under active development.
We've gotten the following to work:
1. Emotion detection with barks
2. Cough detection (Kennel Cough specifically)
3. Identifying a dog from their bark
4. Video analysis of dog behavior
5. Identifying key parts in dog vocalizations (similar to phonemes in people)
6. Some basic intent detection (or what people call translation)
If anyone is good at μpython + TFLite and can help us transferring our models on device that'd be awesome. Currently our set up is super hacky.

#458I'm dipping my toes into decompilation -- specifically, decompiling Super Smash Bros. Melee. Once you get into the groove, it's kinda addicting! Now that I've done a few functions by hand, I'm wondering how to best leverage AI to speed up the process. Come decompile with us! https://github.com/doldecomp/melee

Surface level thinking, ecological disaster in the making. Birds and bats and other bugs eat mosquitoes to live. Killing all the mosquitoes is like the Chinese killing all the sparrows. We do not understand, and we do not want to understand, the deep consequences of our actions.
