Oh, you're writing CUDA kernels? Everyone's on Triton now. Just kidding, we're all on Mojo. We're using cuTile. We're using ROCm. We have an in-house DSL compiler targeting the NVGPU MLIR dialect but wait, Tile IR just dropped so we're going to target that instead. Our PM is on TileLang. The team lead was on CuTe but now she's back to handwriting PTX. If you're not on Pallas, you're ngmi. Our intern is building on TT-Metalium for our Wormholes. Our CFO approved an order for some big chungus wafer-scale chips so now we're porting our kernels to CSL. Our CTO is working on a kernel-less graph compiler so we won't need to write kernels anymore. Our CEO thinks we're talking about the Linux kernel. We're building Claude for dogs.

while FAANG engineers enjoy a varied cuisine and the office barista knows them and their preferred matcha latte by heart.. somewhere in a murky office an NSO employee is slaving away on the next whatsapp chain while feasting on instant noodles 🍜
Oops! While testing WhatsApp, NSO Group apparently spam-reported their own pic of a ramen cup, failing to notice the faint NSO logo visible on the desk mat below. Exhibit in WhatsApp's Motion for Contempt, and a rather fun case study in attribution courtlistener.com/docket/163…

Software Engineering is Largely Solved 2: Electric Boogaloo.
SLOP ALERT: Claude Code UI is complete slop. In the in-app file tree, when u click on a .png, it opens it as a base64-encoded file instead of rendering the image. We’d rather Anthropic not release the desktop app than release an L desktop App. Tons of bugs.

In America, the GPU-richest buy the same things as the GPU-poorest. You can scroll twitter and see Codex, and know that the sama uses Codex, roon uses Codex, and you can use Codex too. No amount of money can get you a better Codex than the one the bum on the corner is using.

You finally get access to Claude Fable but you’re still absolutely right.

Personal update: I’ve decided to resign from my job to pursue my dream of running a ransomware gang. With Mythos dropping tomorrow, there’s never been a better time to get into cybercrime.

I’d like to see more of AI helping build more reliable, performant, higher quality software rather than just the same crap (or worse) at a faster pace.

A 2024 blog post from Andrew Kelley (the Zig BDFL) titled "Why We Can't Have Nice Software". I'm more optimistic about the potential of LLMs but I find this thought provoking and funny. andrewkelley.me/post/why-we-…

Got a (very hacky) working Apple Swift toolchain targeting the original Macintosh 128k (from 1984) 😆

Every now and then, I'll see a comment on here talking about programming languages in a weirdly tribal way, as if they are religious groups. I think it's a mistake to let a programming language become part of your identity as a software engineer (unless you work on the language itself). These things fall in and out of favour and, over your lifetime, you'll likely work with a number of different languages and tools. At this point, I'd happily take an Ada job if I think the work is cool. If you're going to identify with anything as a programmer, I think it's better to choose a domain rather than a tool. Be a security expert, a compiler engineer, a database specialist, but don't be a "C/C /Rust guy".
