The AI cost of JavaScript frameworks
One of my pet peeves with the web development community is that so many of the decisions we make are vibes-based. Frameworks are “blazing fast,” tools will…

Brazilian Court Sanctions Lawyers for Prompt Injection in Court Filing
Two lawyers hid a white-on-white instruction inside a court filing telling the AI to go easy on their case. The court's AI caught it. The fine was $16,000.

Bidirectional charging during grid outages
David asked a great question on my solar battery system post: why buy a small battery just for emergencies when electric cars have a large battery you can also use for other things? [1] This would be great, and seems like the obvious way for it to work: when the grid goes down the panels can charge the car when it's…

The Duty of a Scholar
There was a joke at the time that although the National Security Agency had opened up in recent years and started taking their defensive role more seriously, the one aspect of cryptography which they would never discuss publicly was side channel attacks — and this itself constituted a side channel, revealing the…

GPT-5.6 Sol can beat Factorio on peaceful mode
Edit: Woah, this took off! If you want more details you can subscribe at the bottom of the post or on YouTube. I’m working on a more detailed highlights/commentary post and video. Previously: We got Claude Code playing Factorio, Towards beating Factorio autonomously, and Faketorio: an agent testbed I got GPT-5.6 Sol…

It's the memory latency, stupid
When your database CPU is at 100%, what is it actually doing? Memory stalls, CPU caches, and how radix partitioning makes GROUP BY faster.

Malware uses LLMs to rank victims by how much they're worth
The self-deleting VOLTA infostealer steals credentials, sessions, and cryptocurrency wallets. Then, it uses LLMs to profile victims and rank their most valuable assets.

Jepsen: ParticleDB 1.1.4
Modern applications often spread state across a variety of systems: databases, caches, queues, data warehouses, search indices, and so on. Coordinating these systems is challenging: caches are often stale, the analytics platform might lag days behind the primary database, the search index might lose data, and…

Prospero: A new coding harness for a more civilized age
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…

Mystery of 60-Second Fluctuations in Power Grids Solved
Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as…

Switch Lowering in GCC
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?

Digital minimalism
For a long time I have been a fan of minimalism in my physical life: have few physical possessions, and try to do more with less. Four years ago, I wrote this blog post describing what I had in the 40-liter backpack that I travel around with.

My favourite PowerMac is a Nintendo Wii
So today I reached a nice milestone in one of my projects: my work porting classic Mac OS to PowerPC systems with what I affectionately call ArtX chipsets (Nintendo GameCube, Wii, eventually Wii U; the GameCube’s Flipper integrated chipset was very much designed by ArtX as it was effectively finished when ATI acquired…
