Today is a day of mixed emotions for me. The UK's COVID tracing app is finally closing. The app was, by any reasonable measure, a success. A team of experts at the Pandemic Sciences Institute at the University of Oxford and Department of Statistics at the University of Warwick estimate the NHS COVID-19 app prevented around 1 million cases, 44,000 hospitalisations and 9,600 deaths during its…

I think the computer programming industry is about to reach a reckoning. No, not because ChatGPT can poorly plagiarise buggy code - but because a whole generation of kids have grown up with Scratch. And they'll want professional tools which have Scratch's level of usability. Hand-coding YAML files is a mug's game; one wrong whitespace and everything is broken. Left a semi-colon off the end of a…

I was in one of those interminably dull video-conferences a few weeks ago. The presenter was pitching their grand vision of what our next steps should be. "So!" They said, "Any comments before we launch?" No one said anything. After half a minute the presenter said "As there are no objections, we'll proceed. Silence is consent." At that phrase, my whole body did an involuntary spasm which I'm …

Metawork is so much more fun than real work. Sharpening your pencils. Colour coordinating your filing system. Creating Gantt charts of what you intend to do. Marvellous! In that spirit, here's how I used the venerable pandoc to convert my MSc dissertation from .md into a variety of more readable formats. Prep I've no idea what you already have installed on your system but, at a minimum, you…

Much like "Why I’m No Longer Talking to White People About Race" this is a book that's a little tricky for me - a white apathist man - to review. I'll cheerfully admit that I don't get religion - any religion. And I doubly don't get why people tie themselves to a religion which seems to persecute them. As I read on, I was surprised to discover just how much I agreed with some of these t…

This is a Retropost. I wrote it contemporaneously - but was only allowed to publish it a year later. Today I took part in "A Phase 2/3, Randomized, Observer-blind, Active-controlled, Multicenter Study to Evaluate the Immunogenicity and Safety of Omicron Variant Vaccines in Comparison with mRNA-1273 (Prototype) Booster Vaccine". In the name of science, I allowed myself to be injected with an…

Twitter's decision to hobble its API has meant that a number of useful alerting bots might no longer function. Your local subway might not be able to Tweet each morning about delays on the line, nor will a tornado warning be displayed as you scroll through photos of brunch, and forget about flood alerts between your memes. In one sense, this is sad. A set of useful public services are being cut…

A few years ago, I wrote about my perfect ls command. I always want to see the most recent file at the bottom of the screen, with a human readable filesize, and nothing else. I've started using the exa tool to make that happen. Sadly, there's no configuration file to change its default behaviour. So, I add this to my ~/.profile file: # Better LS with exa alias lh='exa -l -s modified…

After finding the first Expanse book mildly interesting, I was badgered into reading the sequel. It isn't good. The first book made for some interesting "engineering" sci-if. What would it take to travel at excess g-force? What are the practical implications of living on a low-gravity moon? That kind of thing. But it was let down by being a mish-mash of recycled plots - big evil corporations,…

There's an old, old joke: A man jumps into a taxi and starts chatting to the driver about philosophy. The taxi driver turns to him and says, “Are you a Catholic or a Protestant?” The man says, “Well, I'm an atheist.” The taxi driver thinks for a moment and says “OK, but is it the Catholic God or the Protestant God that you don't believe in?” I've written before about the UK's rapid loss of fa…

I needed to copy 3TB of data from my old homeserver to my new one. I decided to spend as much time "sharpening my axe" as possible. I spent ages dicking around with ZFS configs, tweaking BIOS settings, flashing firmware, and all the other yak-shaving necessary for convincing yourself you're doing useful work. Then I started testing large file transfers. Both scp and rsync started well -…

ZFS sometimes benefits from having a logging drive. Usually, you need to assign a whole device or partition to it. Unfortunately, I had already partitioned my SSD and didn't feel like repartitioning it. So, here's how to create a file, mount it as a loopback, and then assign it to your ZFS pool as a logging drive. Create a 1GB file somewhere on your SSD: fallocate -l 1G zil.img Mount the…
