In short: Vim has a joke autocmd called UserGettingBored that doesn’t do anything. Vim’s automatic commands feature, usually shortened to “autocmd”, lets you run code when various events occur. For example, you could implement an auto-save feature by binding the TextChanged ...

Release: llm-anthropic 0.27

This release mainly provides compatibility with the recently released anthropic v1.0.0 Python library, which switches from httpx to httpx2. OpenAI made the same change in their v3.0.0 release two weeks ago.

Anthropic provide this migration guide for upgrading to 1.0, so I prompted Fable 5 in Claude Code with:

Upgrade to anthropic>=1 - read https://raw.githubusercontent.com/anthropics/anthropic-sdk-python/refs/heads/main/MIGRATION.md and get the tests passing

Here's the resulting PR.

I’m no stranger to pushing hardware past its limits. For example, seven years ago, I tracked down an issue that prevented 16 GB of RAM being used in a motherboard that only supported 8. It ended up being a one-line GRUB hack to fix one of the ACPI tables that was mistakenly overlapping a PCI […]

Not mutually exclusive

There many examples of families of functions where each function can be computed as a linear combination of the two previous terms where a and b are functions of x but not on n. This is called a three-term recurrence formula. It’s amazing how often you can run into three-term recurrence formulas. There are theorems that give conditions […]

Probability density function must integrate to 1, and so if you know a density function up to a constant, the constant is determined. When you’re looking at a probability density f(x) for the first time, it helps to ignore the normalizing constant. Concentrate on the part of the function involving x and know that the normalizing […]

Your executable is a SQLite database Farid Zakaria describes a neat Linux pattern for creating a SQLite database file that can be directly used as an executable binary. The trick sets the SQLite file format's 4-byte application ID (68 bytes into the file) to SELF, standing f...

On our recent trip to the Edinburgh Fringe, I was bemused by just how little effort performers put in to finding out why people had selected their show. Taking a show to the Edinburgh Fringe is ridiculously expensive with some performers paying tens of thousands of pounds. The way performers recoup the costs of performing is by getting people to pay to see a show. Acts are spending huge amounts…

It was on August 24, 1995 that Windows 95 was released, amidst much anticipation. It was the most widely anticipated Windows release of all time, and the runner up really isn’t close. The idea of people lining up for blocks

Sean Goedecke wrote a post arguing that you should never be angry at work — a post with which I strongly agree. Anger can be a useful signal, but being angry at work rarely improves the situation. More often, it makes life worse for the people around you, many of whom have...

I genuinely think I've nailed the IoT door lock situation! Well, Ubiquiti has, but I think I've worked out how to put it all into a residential house and have it make sense. There are a few basic tenets:

On my icon gallery sites, I have metadata I’ve manually added over the years to tag certain icons as being predominantly “blue” or “orange” or some other color. Then I use this metadata to present icons of (roughly) the same color. It’s kinda neat to be able to browse a wall...

The matter is too important to be taken seriously.

Anthropic’s best AI model struggles to attract users as cheaper tools thrive A few interesting numbers in this FT story gathered from "people with knowledge of the matter": Anthropic's "annualized revenue" for July is up to $65bn - it was $47bn in May, and I collected more ...

Winter 2025 was the tipping point for coding agents. Summer 2026 is shaping up to be the same for open weights - and compute supply, not model quality, is now setting the price.

Prior to Fable, it felt silly to waste too much time improving your coding harness or context strategies. A new model would arrive at the same price (or cheaper!) and paper over most of your problems.

But then Fable landed. It was (and still is!) incredible. But the cost was so high and Opus was good enough (as was 5.6, K3, and even GLM) for most of the code we needed.

So we started to think about what work went where.

Special functions often have arcane names that not very helpful without some context. The previous post goes into some reasons for this. This post will expand on a point at the end of the post about “modified” functions. Things are given their names for a reason. Discovering that reason helps you understand their motivation and […]

Special functions are special because they’re useful. They can also be shrouded in arcane terminology. These two facts are related. The more widely useful a function is, the more likely it is that the function will be discovered independently multiple times. Independent discoveries lead to varying definitions and notations. For example, there are two widely […]
