Containers have not been a meaningful security boundary for a long time. So why am I hearing people talk about it no longer being one in tool 2026. micro-VMs have been a thing for a while now.

compelled by whom? idk man, but i feel like we collectively sorted South Africa out pretty alright and the situation there is way fuckin’ better! not saying i have any answers but we have an existence proof, that’s not nothing!

“until Hamas won” is an insane way to frame this. what is Likud doing rn? what happens if (when?) Otzma LeYisrael wins? in what universe are two ethnostates run by extremist parties better than a single government, compelled to represent its citizenry more equitably than either would on their own.

then you could use `inspection-testing` to verify that all the edge cases fuse the way you expect to & you don’t fall back to scalar impls except where necessary

autovectorization seems terrible so it’s probably worth starting with (2), but i do kinda wonder if you could produce a set of library functions in the style of (1) that /only/ depend on fusion RULES under the control of the SIMD library itself.

i think we’re kind of stuck with needing to provide APIs like: 1) normal `Vector` stuff, accepts hints for width and just tries to chunk things up according to whatever your numeric + arch allows 2) explicit chunking API that looks more like `conduit` or `streaming`

skyking @jkachmar.com · 29/09/2026
width is annoying though yeah, and it doesn’t help that `vector` is (imo) ill-suited for this sort of work. stream fusion is a cool idea, but implementing it via RULES is fragile and you just have to jump through so many hoops to get everything to play along the way you want it to.

i’m stealing ideas from std::simd & fearless_simd both, yeah. i was gonna ignore SVE and just support NEON tbqh.

skyking @jkachmar.com · 29/09/2026
i think x86 SIMD w/ scalar fallback implementations for all the things you want to accelerate might be more evil than CUDA tbqh. maybe it’s just been too long since i’ve used CUDA but this is just sort of miserable from the PoV of providing a consistent API.

every time i see someone commenting on how different a new model release is, along with how it’s changed the game for them, i think of sommeliers commenting on the differences in terroir between two small patches of vineyard maybe a few kilometers apart.

part of the NJ miss was young men showing the fuck up for Sherrill in a way no one had priced in right? NJ obviously isn’t demographically or ideologically Maine (not old-white enough) but it does surprise me to see people being skittish given how much NJ & VA blew expectations the fuck out.

Since we’re doing another round of “AI will destroy humanity” doom-hype, it’s a good time to announce a new paper myself and my postdoc advisor just had accepted by BioSocieties on just this. TL;DR: almost all the “AI can make bioweapons” literature comes ultimately from the Effective Altruists.

i wish the sequel trilogy had called back to the old republic. “death star 3: this time it‘s a planet” was extremely lame, and i just think it would have been cooler to frame the First Order as having shown up all of a sudden from the unknown regions with a brand new but suspiciously ancient fleet.

i think it’s cool that Ptacek is dedicated to volunteering in support of his local elections & such and i‘m going to use AI to build a filter so those are the only of his posts i ever read because over the last year his tech posts are all discourse bombs.

i really can’t bring myself to care about AI anthropomorphism debates. “is AI thinking?” i don’t know. is a calculator calculating? questions for the philosophers. what’s important is that we put sam altman in prison.

The problem with education is that it's a solved problem. Students need small classes, individual attention, lots of writing, lots of feedback, access to a well-stocked library, time to think, and time to talk with their peers. We just don't like the answer, so we keep trying to do other stuff.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

AP Stylebook warns against anthropomorphizing AI systems: “Avoid language that gives them human characteristics… Instead, explain what a system does, how well it performs, who built it and who could be affected by it.”
APStylebook @APStylebook
X.com
Artificial intelligence systems do not think, feel, want or understand. Avoid language that gives them human characteristics. This is called anthropomorphizing, when we ascribe human traits, emotions or behaviors to non-human things, such as animals or inanimate objects.
Instead, explain what a system does, how well it performs, who built it and who could be affected by it.

basically i think my position on this stuff is that if you are a software engineer who think LLMs are going to fully automate the software engineering process it’s probably a function of depression/low self-confidence and a nihilistic worldview. tragically, this covers a LOT of software engineers.

…but without /something/ to provide this grounding you’re basically fucked over the lifetime of the project. not having this stuff is how you end up with Gastown: a product that is completely inscrutable, architecturally decoupled from reality and with no real purpose at all.
