Make sure you watch the Big Blue, in the original French (not US, has the wrong soundtrack) version, but with the original(!) English speech, not the dubbed-to-French version.

New comment by jacobgorm in "Sweden becomes a smoke-free country"

jacobgorm — Tue, 26 May 2026 21:59:55 +0000

Smoke free perhaps but not nicotine free by far. I live in Denmark and have a teenage son, he tells me that 90% of girls at his year are hooked on illegally imported and unregulated vapes, much stronger in nicotine than cigarettes, and in some cases loaded with fentanyl and other drugs. We have had the first couple of deaths of 15-year olds already.

Meanwhile, the parents' generation and politicians are looking at the declining cigarette sales (and declining tax revenues) and are busy declaring victory and self-congratulating, with no idea what is coming.

New comment by jacobgorm in "Removable batteries in smartphones will be mandatory in the EU starting in 2027"

It is not that long ago that smartphones would die from moisture exposure if you left them in the bathroom while taking a shower. I had a girlfriend around 2001 who spent all her savings on a shiny new Nokia 8250, got drunk and barfed on her jacket. The phone was in the pocket, and the moisture from the wet jacket completely killed it, she cried about it for weeks. I also remember my mother dropping her iPhone 6 in the harbor while getting off a boat, it got picked up but was dead. Last year I was out hiking in the rain, and my aging (5+ years old) iPhone 11 got water inside it and started dying soon after (I'd been sailing/swimming with the phone and had exposed it to salt water, apparently that will wear down the seals if you do it enough.)

In other words, I absolutely see the need for waterproof phones, even for ordinary people doing ordinary things, and am never going to buy one that isn't.

In Denmark, wind mills were initially quite popular, because locals owned them and benefited. The iconic wind farm Middelgrunden on the waters outside of Copenhagen is 50% owned by a co-op.

Good point, an int3 is not going to be faster than a syscall, and if they implement the sandboxing policy in guest userspace is seems it would be quite easy to disable.

I think the point here is optimizing for the common case, the untrusted code is still running inside a VM, so you can still trap malicious or corner cases using a more heavy-handed method. The blog post does mention "self-healing" of JIT-generated code for instance.

It is possible to restrict the call-flow graph to avoid the case you described, the canonical reference here is the CFI and XFI papers by Ulfar Erlingsson et.al. In XFI they/we did have a binary rewriter that tried to handle all the corner cases, but I wouldn't recommend going that deep, instead you should just patch the compiler (which funnily we couldn't do, because the MSVC source code was kept secret even inside MSFT, and GCC source code was strictly off-limits due to being GPL-radioactive...)

Show HN: Witchcraft and Pickbrain – fast multi-vector semantic search in Rust

jacobgorm — Thu, 16 Apr 2026 12:42:49 +0000

Witchcraft is from-scratch Rust reimplementation of Stanford's XTR-Warp (SIGIR'25, https://arxiv.org/abs/2501.17788 ) multi-vector semantic search engine. Witchcraft runs out of a single SQLite database, is blazing-fast (21ms p.95 end-to-end search latency on NFCorpus on a MacBook Pro), accurate (33% NDCG@10), and easy to deploy in your own apps. The Witchcraft repo also comes with Pickbrain, a sample app and agent skill that you can use to instantly query across all your Claude Code and Codex CLI sessions, effectively giving your agents global long-term memory. Please see the Github page for more details, and feel free to ask questions here, and I will try to answer them.

I have been developing local AI on Apple devices since 2019, and they already had great AI support via Accelerate and MPS back then. Contrast to the Windows DirectML fiasco, which was basically just finger-pointing between MS, Intel and AMD all saying “it works on my machine” for years, I would say that Apple was always far ahead and did invest where it actually mattered to developers and users.

When I lived in the US I was surprised about how casually everyone treated DUI. In Northern Europe, where I am from, driving after drinking is socially unacceptable in Generation X and younger.

GameGlobe from Haptico and Square Enix, the engine of which also powered Project Spark from Microsoft, also used an SDF engine. Former colleagues of mine built the tech in Copenhagen and I remember getting a super impressive demo back then. This was the first time I heard of SDFs.

In Northern Europe we have lots of fast chargers now, and apart from Tesla, which is open to anyone with their app, none are tied to a particular car brand. I’ve never encountered problems fast-charging my BMWs. Most cars you can buy today have the option to pre-heat the battery, but it is possible that not all owners know how to activate that. The newer Renaults run on Google software, which is said to be very user friendly and good at route planning.

At least in Denmark where I live, since Tesla started competing on cost a few years ago, and then the DOGE fiasco. It’s the car you get if you’re already a Tesla owner and hardcore believer, or just see a car as a means of transportation and buy purely on specs. The days when Teslas were status symbols are long gone. We can buy so many other interesting EVs here, for example I just had a friend who was an EV hater six months ago come by showing off his brand new Renault R5 today. That car has 10x more character than a TM3 and costs less even if he got it fully loaded. VAG has a very strong lineup of TMY competitors that combined are vastly outselling it, and so has Kia/Hyundai and Renault. Those with more money will go for BMW, Mercedes, Audi, or even Porsche. And then there are all the Chinese brands starting to make inroads. Most here see buying Chinese as less problematic than buying Musk.
