SpaceX has almost finished writing V1.0 of an in-house AI training stack in C that exact-maps to 220k GB300s with 800G NICs, making heavy use of pipeline parallelism and getting as close to bare metal as possible.
The potential speed improvement vs JAX for large training runs is over an order of magnitude.

@aarondfrancis are you open to a bit of Postgres consulting regarding index design for our query patterns? If not, do you have any recommendations?
English

@JackEllis You removed the usleep(500) you added a while ago for testing?
English

@calebporzio B. Assuming ranges can also have an open start or end. A ‘fake date’ doesn’t communicate all time as it strictly is just a broad range. In most implementations, all time means not filtering, option B feels like it communicates the best.

@DJSnM Seems like it disintegrated and pieces came down much closer to home
English

@PatrickLipsinic @DJSnM Yeah spotted that as well now. Wasn’t instant boom judging by telemetry though
English

@georgeboot @DJSnM There was a fire at one of the aft flaps

@JackEllis Lol didn’t even know this existed now. Years ago we rolled our own version but it was hacky AF but did the job. Do you use uuid as PK or as a regular column? When using as PK it’s going to benefit your index sizes hugely, which was our main argument.

@SpaceX Does anyone know why it was scrubbed this time

@alex_ Yeah we also had something similar. Probably chunk it up in smaller sub jobs, store their output as temp files and combine at the end into a single large files. (Disk IO is much much faster than database). Job batches and chains are your friend with these issues.

@georgeboot The job I'm working on is a large JSON export (single file), so a little annoying to split it into smaller jobs. I hadn't considered the deployment issue yet either. Currently, the graceful shutdown timeout is 60 seconds, which will also be a problem 🫠

Any tips for handling large #Laravel Horizon jobs more effectively? Getting [job] attempted too many times usually points to OOM/timeouts, but debugging is tough - especially with 30min+ execution times and retries. What's your approach?

@512x512 It feels like grok is using the web more and more as of recently, but the sites it cites are often garbage. When I ask it how does x work, it comes up with a definition based on tv reality show clickbait articles, not some sound and true definition.
English

@JackEllis Haha jup, but the pro does it all, just manual. I once almost bought a second hand oracle touch (they hardly wear, so why not) but someone else snagged the deal from me :-(

@levelsio Are you sure? Judging by its initial speed the flaps were extended then, so they did initially work. Gears can also come down with gravity, and there are also the electric actuators for flaps (for when both A, B and standby hydraulics failed.
English

Also every 737-800 has a BIG ASS checklist staring you in the face on your yoke
So with all the alert sounds and checklist kinda hard to forget your landing gear is up when you land
So seems more likely it's just a full hydraulics failure because flaps and speed break also didn't work!

Here's how it sounds if you land a Boeing 737-800 with your gear up This is at Maun Airport in Flight Simulator

@productive_will @adamwathan Some have, but in my experience it’s only booking time to issues. Meetings and other admin don’t usually fall in that, but are still linked to a project.
English

@georgeboot @adamwathan All project management tools should definitely have that built in
