You can use a buck converter as a buck-boost converter. As in, get negative voltage.
I just checked. On paper. And guess what? They are nearly identical. The schematic of one turns into the other.
The only difference is the negative side of the input capacitor.
Mind=blown.
There are application notes for how to reconnect your converter, but even they don't notice it's THE SAME TOPOLOGY! https://www.ti.com/lit/pdf/slyt286

You need a 1234 GiB GPU to run your program?
Let me play you the tiniest... #microcontroller breakout board!
The 10-cent CH32V003 microcontroller and a single capacitor make a complete breakout board. Honestly, I didn't even need the PCB. The capacitor could be soldered directly on the pins.
I flashed it with the #Arduino . Not so "Nano" in comparison! #ESP32 for scale.
And it has #Rust support!

@nprofile1q... That would be security by obscurity, but that gets broken too. Proof is all the challenge and puzzle websites where no one shares the actual code, yest they get solved.
Best OPSEC is never to communicate. Not between computers, not between humans :)
Also, bring back TempleOS :D

Dude, that's my #N900 with an OS from 2007. It's using #rsa and I had to make an exception in two places to even make you connect. On a private network.
#Quantum computers are the least problem here.

@nprofile1q... Correction: unless someone posts a different link, cloudflare is stopping me from reading.
A Google DeepMind researcher just published a formal argument that AI cannot be conscious, ever. Not biology, structure. Computation is a description, not a process. A conscious mapmaker has to exist ...
@nprofile1q... Before I read the article, computation is a description of something that is happening. If you reect the notion that the computation on its own has meaning, remember that the computation describes *something real* underneath. Symbols don't exist in the air, but on a substrate that they actually influence.
When people say that the universe cmoputes, they don't mean that it manipulates symbols, but that transformation of matter are describable by computation.

@nprofile1q... I always put the limit of "no thought given" ride at about 30km. No matter the weather or health, just go.
50km is 2 hours, so it's nice to have a goal or I'll find myself cutting it short.
Except in winter when 10km is enough to you freeze your fingers off. Anyone knows good gloves?

@nprofile1q... @nprofile1q... @nprofile1q... @nprofile1q... Persulfate was the first method that I found that promised relative safety, that I could easily obtain, and at the same time was adequately explained.
I could switch now, but then I'd have to spend the time tracking down the exact reactions and safety data sheets for disposing all results for both processes, not just one.
It does seem a bit slow, and I don't have all the disposal details pat down yet.

@nprofile1q... How does that work?
This is the first season I reapplied lube but I never bothered to fully clean a chain.

@nprofile1q... @nprofile1q... @nprofile1q... I'm using the regular Bungard boards from Reichelt. I can never tell if that's called positive or negative. Exposed areas disappear.
For now, I'm warming it by pouring hot water to the bowl once or twice per board, and I'm agitating manually with the pictured tool. The good part is that I know immediately when it's done :P
But yeah, I'll have to find an aquarium heater.
