The linked article says they decided to do CD in 2016 fwiw so that's not inconsistent with what I said. You reduced the number of patches a lot and also pushed very hard to get us …

For the peanut gallery more: I worked with both of these guys at Meta on this. The "servers are only on for a few hours" thing was like never true so I have no idea where that clai…

I did something similar a long time ago https://github.com/facebookresearch/py2bpf It was definitely a toy, I transliterated from python bytecode (a stack based vm) into bpf. I als…

Not sure it’s relevant in the cloths these guys take

The cloud business model is to use scale and customer ownership to crush hardware margins to dust. They’re also building their own accelerators to try to cut Nvidia out altogether.…

I’d imagine that these clouds are probably being incentivized to participate

I don’t think pivot_root is necessary for something like this, but a new mount namespace will definitely help avoid creating a mess on accident

More low effort posts please!

Sharing a queue itself is not new https://www.kernel.org/doc/html/v5.8/networking/packet_mmap.... and https://docs.kernel.org/next/userspace-api/perf_ring_buffer.... are two exampl…

The thing that we need in order for your dream to become a reality is excellent user space frameworks, so I encourage you (and anyone else) to go build one or (better) find one you…

> File IO is perhaps the best example of this (at least on Linux). To handle such cases, languages must provide some sort of alternative strategy such as performing the work in a d…

Yeah that’s it. Probably just wasn’t supported in the rust age library when I used it. Will double check.

Age is great. I used the rust crate to write an ftp server that encrypts the files before they hit disk (specific use case is having a drop box for my network scanner) and I love t…

The core framework (sched_ext) was written for general workloads and can quite beneficial. It lowers the costs of creating and iterating on schedulers quite a bit. To be honest, wh…

Latency and cache coherency are the other things that make this hard. Cache coherency can theoretically be resolved by CXL, so maybe we’ll get there that way.

Or perhaps more accurately, throughput is not the only goal.

A professor actually told us that freeing prior to exit was harmful, because you may spend all of that time resurrecting swapped pages for no real benefit. Counterpoint is that deb…

As a Meta employee, I consider this a victory against NIH :)

OpenAI's recruiting pitch was 5-10+ million/year in the form of equity. The structure of the grants is super weird by traditional big-company standards, but it was plausible enough…

Even if the laws are stupid, the killer feature you are describing is called crime.

IME, familiarity with /etc/nsswitch.conf and the rest of the nss stuff is very highly correlated with people who have seen some shit.

I still remember when I came to you with my “attachments shouldn’t live in the mssql database” plan and you said “yeah, probably, but doing it any other way would be a million time…

It was a joy to work with you as well :) It's a bit harsh but I always feel like Fog Creek might be the cautionary tale in "what happens if you over hire for capability vs. your re…

I had an internship at Fog Creek and would add that it was probably the most friendly and harmonious place I worked, which made it very reality-show-incompatible (and very 21-year-…
