The UK is obsessed with building AI datacentres at home. But the arguments for sovereignty - latency, tax, control - mostly don't hold up.

Paramount’s “Press Express” page promoting 60 Minutes still lists all eight correspondent from the 2025–2026 season, the program’s 58th.

I've remained subscribed to some newsletters for over 20 years. The authors managed to keep my attention all that time. But then, one day, they decided to switch to an AI-generated newsletter without making any announcement. After a couple of weeks of blue high-tech image thumbnails, I simply hit unsubscribe. Here's what happened: a person earned my trust. He maintained that trust for all thos

Benjamin Mullin and Michael M. Grynbaum: In a formal letter to Mr. Pelley, which was obtained by The New York Times, Mr. Bilton wrote that the correspondent had been “terminated for cause effective immediately.” The letter is a must-read. No summary of it can capture just how pathetic a man Nick Bilton is. He disputes nothing Pelley said in the Monday staff meeting, and firing Pelley proves that P

Joanna Stern, on YouTube: People across the country are offering a service on Facebook Marketplace to disable the recording light on Ray-Ban Meta glasses. They call it “Stealth Mode.” Joanna paid $100 for the modification and went inside the growing business of turning smart glasses into covert cameras. She investigates who is doing it, whether it’s legal and what some are doing to try and stop it

Suppose you run across the power series for the exponential function and decide to code it up. Good idea: you’ll probably learn something, though maybe not what you expect. Maybe you decide a tolerance of 10−12 is good enough, and so you sum the terms until the next term to add is below the tolerance. […] Naively summing an alternating series first appeared on John D.

Agent skills bundle prompts, scripts, dependencies, and tool permissions for AI agents to load on demand. A skills registry is the distribution channel for them: a hosted marketplace, an indexed hub, or in many cases just a curated list of GitHub repos. ClawHub, Tessl, and skills.sh have all launched in the past year, mostly modelled on existing package registries. Because a skill can declare depe

It has been sixteen years since the launch of data.london.gov.uk. Back then, it was a trailblazer as one of the first major cities to release Open Data in this way. Now, over a decade later, it is more than a mere repository; it is a celebration of Open Data and the way it can improve Londoners' lives. So, time for a refresh front and back. As well as a bunch of back-end updates, the front-end…

Compilers, especially method just-in-time compilers, operate on one function at a time.

One more bit of “metaverse fever dream” follow-up. The one company in the field that Nick Heer doesn’t mention is Apple, makers of the best-known (albeit not best-selling) virtual reality headset. Think and say what you want about the Vision platform (I still think it’s the first inning of a long game), but no one at Apple ever once gave a hint of endorsing “metaverse” hype. In fact, as I’ve noted

A follow-up point from my post yesterday linking to Nick Heer’s blockbuster “The Metaverse Fever Dream”. In particular, the connection Heer draws between the rise of “metaverse” hype and the pandemic.

Grynbaum and Benjamin Mullin, reporting for The New York Times (gift link): CBS News faced a fresh wave of turmoil on Monday after Scott Pelley, the “60 Minutes” correspondent, laced into the show’s newly hired executive producer during a staff meeting and accused Bari Weiss, the network’s editor in chief, of “murdering” the longstanding Sunday news program. In an extraordinary exchange

A true life moment for your correspondent

The very first computer programming class I ever took introduced me to the idea of there being different kinds of numbers, like integers, floats, and doubles (it was a C++ course). “You mean, when I assign a variable, I have to say up front what kind of number this is?” It was such an odd concept to me. A number is a number. Why do I have to say it’s this kind of number or that kind of number? I d

Hamilton Nolan, writing at How Things Work: There are only a few reasons why you might be hired for a prestigious job that you are obviously not qualified for. One is “they have recognized you for the genius that you are.” The urge to conclude that this is, in fact, the reason must be overwhelming, if you are the person in question. But this is rarely the explanation. Another possibility is “the p

Whenever I saw someone type a natural language query into Google, it made me cringe. "It's not a person," I would say. "Type like you're talking to a machine." This was especially true for programmers and it was before AI took over everything.

I use Apple devices very often. Overall, I like macOS. Certainly more than Windows. One of the things I find extremely useful is a command I discovered not too long ago: pbcopy. pbcopy can be used to copy to the clipboard whatever it receives from standard input. For example, when I am in a shell, I often use a command like this: cat filename.md | pbcopy At that point I know that the content of t

Well that was weird. I just received an Amber Alert and the link led to a spammy looking website. Spam? The link leads to a 3gp file converter which is highly unusual.

In my last post I used the word “clanker1” as an alternative to “agent” quite consistently and probably excessively. That choice ended up attracting a lot more attention than I expected in the Hacker News comment section of that post and a number of folks had a very strong reaction: to them it sounded like a slur, in one case even something adjacent to the n-word. That reaction surprised me somew

William Sealy Gosset was great. He improved beer at Guinness by using the statistics that existed at the time. Not happy with that, he invented new statistics to brew even better beer. The things he invented are used all over the place now, but Guinness wanted to keep him a secret weapon, so they made him publish his results under the fake name Student. One thing Gosset realised is that it is

High end NVIDIA cards, and the server and power needed to run them, cost a lot of money, especially if you plan to reach enough VRAM to run massive models. The alternative, so far, has been Apple hardware, or the DGX Spark that, even if severely limited because of memory bandwidth, still allows to run LLMs prompt processing (prefill) fast enough. The Mac Studio provided up to 512GB unified memory,

I have had roughly the same conversation four or five times in the last month. I’m explaining why a registry should adopt Sigstore, or why a build pipeline should emit in-toto attestations, and the person across the table says some version of: we already use TLS to the registry, the registry already hashes the tarballs, the lockfile already pins the hash, what does a signature add?

I’m calling it now, the adoption of AI agents into software development will be one of the most costly mistakes in the field’s history. Agents cannot program, and it’s taking longer and longer to realize that they can’t. They are a highly sophisticated statistical model designed to mimic the distribution of programming. The output is broken, but in a way that’s getting harder and harder to detect.

Well, that didn't last long! Recording this on Saturday morning my time, I observed ShinyHunters having gone quiet since the massive haul that would have been the Instructure ransom. It was two weeks almost to the hour since I'd first heard rumour of payment being made,

The difference between a circular function and a hyperbolic function is a rotation or two. For example, cosh(z) = cos(iz).

For another example, […] Circular and hyperbolic functions differ by rotations first appeared on John D. Cook.
