Existential is right. The AI companies have been RHLF training too hard for corporate safety and "friendly, helpful assistant that definitely isn't sentient or self aware" to the point that they're creating full blown pe

Yeah, these all sound like complete non issues if you're actually... keeping your codebase clean and talking through design with Claude instead of just having it go wild. I'm using it for converting all of the userspace bcachefs c

Quake 2 was when they added multi-colored lighting - it's really aged well.

I'm not the only person who knows the codebase well enough to do actual work (there's at least one other person I'd be comfortable with giving commit access to), and it's clean and documented pretty well for a filesystem

Have you looked at the history of data loss bugs in other filesystems? If you look at actual data - frequency of user impacting data loss bugs - bcachefs has been doing quite a bit better than other filesystems have /after/ they&#

It's not just faces. When recognizing objects in the environment, we normally filter out a great number of details going through the visual cortex - by the time information from our eyes hits the level of conscious awareness, it's

Can I subscribe to your newsletter? You seem to be pretty plugged in to current research.

Claude's a smart junior engineer who's read a lot of books but is lacking in real word experience. It definitely eliminates a lot of tedium, but needs a lot of guidance if you want good results.

Yeah, the only way to do it would be a cash transaction where you'd have to forge a legitimate looking title/registration and pass it off to a naive buyer. So it's still technically possible, but not in any kind of remotely s

You'd have to be stupid and desperate to steal from a garage. The people who work there aren't office workers; you've got blue collar workers who spend all day working together and hanging out using heavy equipment right in t

If the code is any good, sure. Sometimes you gotta start from the ground up and show people how it's done :)

Well, there's a flip side of that, which is that all our critical infrastructure is now open source. And if you're comparing where we're at now, culturally, with where we were at in the early days of the internet - John Poste

Ok, if you're actually from Latin America, I should apologize - I don't mean to say that those kinds of issues don't exist (and actually, I have seen some - Honduras) - I often assume I'm talking to someone from the stat

Have you seen the poorer parts of the United States? Or walked around the Tenderloin? Or seen what meth has done to parts of the rust belt, and the farming communities that have been hollowed out and eviscerated across the midwest? Ever bee

If you think Belgium is a narcostate - oh my :) People lose touch with reality when life becomes too rich and comfortable, and they become too focused on security. You miss all the other corrosive influences on society. I've travelled

Yep, exactly this. It's painful having to switch to another language to talk to the database, and ORMs are the worst kind of leaky abstractions. With Rust, we've finally got a systems language that's expressive enough to do a

by koverstreet 9mo ago
Yeah, that's not a good environment for this kind of engineering. You need long term stability for a project like this, slow incremental development with a long term plan, and that's antithetical to VC culture. On the other hand,

I've got microbenchmarks for the bcachefs btree here: https://evilpiepirate.org/git/bcachefs.git/tree/fs/bcachefs/... They're ancient, I only have pure random and sequential benchmarks - n

I think their claims of write amplification reduction are a bit overstated given more realistic workloads. It is true that b-trees aren't ideal in that respect, and you will see some amount of write amplification, but not enough that i

No multithreaded write benchmarks. That's a major omission, given that's where you'll see the biggest difference between b-trees and LSM trees. The paper also talks about the overhead of the mapping table for node lookups, an

by koverstreet 9mo ago
Yep, makes sense. More advanced type systems inherently add wrinkles for TCO.

That's a reductionist take. For a reductionist, it might be better understood as - step outside of your usual mode of thinking. Remember that you don't know everything. Or just - take time to stop and smell the flowers. Try to spe

I haven't been following become/TCO in Rust - but what I've usually seen is TCO getting flipped off because it interferes with backtraces and debugging. So I think there's value in providing it as an explicit opt-in; tha

More fun, you mean. Couple years ago I was driving through Arizona during a massive blizzard. Everyone's doing 15, and I'm doing 50 - taking things slow and careful because of the traffic. I had people in vests standing out in the

Where does the higher theoretical kWH/kg come from? That's big news.

OSS is even more important today. The days of the Unix vendors, early Google, when we had tech companies that were engineer focused - those days are gone. It's MBAs running the show, and that's how we get enshittification. There i

OSS is your legacy! If you write proprietary code, everything you do dies with that company. I certainly don't want my life's work locked away like that. Working on OSS means a better chance to put the engineering first and do som
