Shortly after writing my previous post, a colleague pinged me to say she’d figured out what was wrong – at least at the most immediate level, i.e. the exception itself. Nothing is wrong with the ordering code – it’s just that the exception message is too easy to misread. She’s absolutely right, and I’m kicking … Continue reading Election 2029:…

I really thought I’d already written a first blog post about my Election 2029 site (https://election2029.uk) but I appear to be further behind on my blogging than I’d thought. This is therefore a little odd first post in the series, but never mind. To some extent it isn’t particularly related to the election site, except … Continue reading Election 2029:…
Most PG&E ratepayers don't understand how much higher the rates they pay are than what it actually costs PG&E to generate and transmit the electricity to their house. When I looked into this recently I was shocked. The average PG&E electricity charge now starts at 40 cents per kilowatt hour and goes up from there. […]
Back in 2020, when I worked in the supply chain side of Google, I had a fun and impactful side project related to human-level explanations of linear programs. A linear program is a mathematical model that defines some number of variables, linear constraints, and a linear objective function. When some variables are forced to be integer (ILPs), you can solve…

WHAT IT IS Meta’s Automated Compliance Hardening (ACH) tool is a system for mutation-guided, LLM-based test generation. ACH hardens platforms against regressions by generating undetected faults (mutants) in source code that are specific to a given area of concern and using those same mutants to generate tests. When applied to privacy, for example, ACH automates [...] Read More... The post…
A few weeks ago I ran a terminal survey (you can read the results here) and at the end I asked: What’s the most frustrating thing about using the terminal for you? 1600 people answered, and I decided to spend a few days categorizing all the responses.

This is particularly true in the data center [...] Read More... The post…
Net losses shrink by 55% as management declare ‘clear path to profitability
A lot of us as developers have hi-DPI screens, and we can easily forget to test the websites we build on low-DPI screens. One common issue I noticed is that thin font weights can be hard to read on low-DPI screens. Since there are fewer pixels to render details, fine lines can appear blurry due to anti-aliasing. Here is an…
Most developers know about red teams: a specific group of people chosen to be the antagonist to your system, trying to sniff out vulnerabilities in your code or organization. Basically, like Sneakers, or the annoying plotline in The Newsroom season two. (Someone should have really red team’d Sorkin himself on that one.) There’s a few other concepts of a red…
