when i was a baby my dad was driving me late at night and a drunk driver asleep at the wheel hit us head-on. my dad was in a coma for weeks. i needed hundreds of stitches. i still have a massive scar. many years later, i got to work at waymo during the first few years we were testing, launching, and scaling in sf. there was a huge amount to do, but it all felt pretty fucking amazing when we got to see logs like this. superhuman moments. it's easy to write off these things as just another expensive uber competitor for techies who don't want to talk to people. but humans behind the wheel are one of the top causes of death and injury globally. and one day not long from now self driving cars will make the kinds of accidents that happened to me a thing of the past.

@steeve @IronRedSandHive @CatGodSandHive @RealTjDunham I would very much like to see this. Splitting up monolithic NVCC invocations into separate & more granular cubin + host code compilations would be a huge improvement to the ergonomics of CUDA in Bazel.

@IronRedSandHive @CatGodSandHive @RealTjDunham Literally working on a demo as we speak

We managed the holy grail of CUDA compilation: joining CUDA host code and device code at *link time*. This means both build graphs (device and host) are now completely separated and built by SM. True scalable CUDA build graphs are now possible. Those who know, know.

@corentinanjuna @bazelbuild @buildbuddy correction: one --cubin per arch, not --fatbin

@corentinanjuna @bazelbuild @buildbuddy This is cool to see. I've spent a bunch of time thinking about this since it seems so close to being possible to stitch together just from the provided NVCC commands, i.e. some combination of per CUDA arch --fatbin actions and one --cuda for the host side + kernel inclusion.

Current status and coming soon: Compiling flash-attention kernels with @bazelbuild and #llvm for all Nvidia Compute Capabilities, 1 action per sm_xx per kernel, fully parallel, hermetic and remote, in 5 minutes. 🫶 @buildbuddy for providing the cores <3

@deepinthebuild I don't!

The more self-aware and aware of others you become, the less you generally take personally. Everyone's actions are reflections of their nervous system, history, emotional state, etc. and we tend to over-represent how important we are in determining people's reactions to us.

@grhmc @isabelrosesss I imagine at this point you just have one big button that is a macro for this sentence

@isabelrosesss nix fixes this

keyboard but you only have the keys for writing "nix fixes this"

spending the family trip convincing my nieces that it's "bananas bread" just like "attorneys general"

"not my circus but I definitely recognize some of those monkeys and have tips on how to manage their behavior"

@aliceisplaying talking to Chat

a note for The Watchers,

fun start to my week: setuptools published 82.0.0 yesterday and finally dropped pkg_resources entirely, breaking wheel builds for a bunch of packages that had setuptools in setup_requires with no upper version bound (which they tell you not to do anyway)

@RachelZader ouch

My hairstylist must be sent to the gulag

@JRROwens @toxictiramisu This book seems to be somewhere in the vicinity of conspiracy theory or creative fiction. I can't find any other works discussing the events as described but I can find reviews trashing this book for its lack of primary sources and shoddy history.

In 1939, after a pope's death, the Nαzis sent an SD agent to the conclave with a gold shipment to influence the papal election: Operation Eitles Gold. Vatican intelligence intervened; the Assassini killed the agent, and the gold was recast & quietly banked, disappearing forever.

@helloitslynne would recommend "The Ascent of Money"

@__phantomderp I had a shower thought and figured you were the most likely person to know the answer: Has C converged on the C++11 memory model for atomics?

@kramerposts this is the "If you give a mouse a cookie" phenomenon

Is there a word for this thing where you try to solve one problem and the solution creates another problem that is at least as big as the one you were trying to solve? Problem cascade?

@shaggysurvives @allgarbled not much, you?

@allgarbled whats kubernetes

That, and to be a relentless enemy of tools and workflows that my users or I find annoying.

More and more I view my role as similar to that of a music producer: I don't work directly on the product but I'm there to shape the process, help people avoid painful mistakes, and to have good taste.

Out in SF again later this week, hit me up if you want to grab coffee or dinner.
