@hillelogram I asked my agent for a proof two months ago and it hasn’t stopped working on it…

[Ulf Adams @ulfjack]

@hillelogram If you ask for a proof or a bug you’ll always get a bug, so that’s trivially true.

Reverse engineering Märklin train track geometry. Can anyone confirm that it’s based on a 5/6 mm unit? I have no idea why that would be the case but it makes all the lengths integer and rounds to the catalogue numbers.

@marcaruel I would have gone with the facepalm emoji but i guess heart will have to do.

Thanks Claude…

@sluongng You should track your input and output tokens so you can see your own usage.

Me: Huh, interesting that go gzip generates larger files than normal gzip.

*one hour later*

Opus: That’s because it doesn’t emit 3-byte matches. Here’s the original source and a histogram I got from a gzipped file.

Wait, what?

Quoting Claude: „Log first, theorize never.“

Words to live by!

[Ulf Adams @ulfjack]

@pepicrft Yes.

[Ulf Adams @ulfjack]

@marcaruel So much so!

[Ulf Adams @ulfjack]

@jonobelotti_IO We had 1389 commits. Not fully comparable but close.

@pepicrft @Dimillian The GPU in the grill doesn’t get hot enough with Codex so they had to switch.

Highly recommended reading if you’re interested in processor architecture.

My only concern: it spends a lot of words on the easy stuff and then glosses over the advanced stuff.

@MainzOnX Way too dangerous!

@marcaruel I’m running the quality version though.

@marcaruel Crashes in llama.cpp on Linux on a RTX 5090. Haven’t yet figured out why.
