Hey #electronics nerds, where do I get a bunch of those ONLY in red and black?

Rainbow is cool but *each* of my breakouts and spiders needs red and black jumper wires, throwing things out of proportion...

#Censorship in #LLM s is achieved by fine-tuning. What are the most current base models available to run locally, without censorship, and without tuning to fit a specific task?
It's kind of hard to figure out from huggingface model sheets.

How do I modify builtin #Javascript objects?
In #Firefox I can do:

Object.defineProperty(window, 'performance', { value: undefined });

but if I put it in #Greasemonkey it does nothing :(

#photography question:
Do #macro converters reduce quality a lot?

Vignetting, blurring, chromatic aberration? I'm kinda weak on #optics this advanced.

I wonder if I should buy one. I already have an extension ring but attaching it is a bother.

Are converters sensitive to optics quality? Used cheapo or 3 times the price for the original #Olympus MCON-P01?

Shame that there's no superzoom lens with macro in #MFT :P

Solder paste on a PCB is like salt on a dish.
It's easy to add, but difficult to eliminate.
#SMD #soldering wisdom โ„–684: not enough solder paste is strictly better than too much.

Unless you like bridges.

I enjoyed #rsync remote file completions for a while, but I upgraded to #Fedora 44 and now it chokes a few directories deep into the path :( I suspect some #bash expert failed on a whitespace inside the directory.

3rd attempt at #ESP32 .
Lessons:
- Pay attention to values
- Don't cross wires
- Use flexible cables or you'll tear off pads
- Verify design rules or you'll forget stuff
- Break out #UART even if you think you won't need it (you will)
- #UVTools has #Gerber rendering issues
- Don't cross wires!
- Oscilloscopes are gold
- 120ยฐC solder paste on a hot plate works great

#USB is simple, yet I had to fix 3 mistakes before it worked.

@nprofile1q... Ah, I see. That sounds like the same concern that made UUIDs.
Thinking more along this way, I've seen intentionally reused ISBNs. I'm guessing that's because it costs something to get a bunch. UUIDs are completely gratis to generate, so there's no such temptation.

So it looks like UUID is superior in this aspect, except it doesn't come with a cental database.

I have a hunch that with crowdsourcing, a central database isn't needed any more, making UUID a viable alternative.
