Vague thoughts as they enter my brainbox. The BlueSky social network has introduced "Reply Gating" - it looks like this: You can write your hot take on Taylor Swift and not be inundated by weirdos replying to you. Nifty! This is nothing new. Twitter has it. Facebook has the concept of "audiences" to restrict who your post is visible to. And, of course, blogging has this! There is a comment …

I thought I didn't know Tchaikovsky's Swan Lake. But, like all truly great cultural phenomena, it had disseminated itself through the cultureweb so thoroughly that I felt completely familiar with it. Performed in the round, from our nosebleed seats we had a stunning view of the action. The full floor of the Royal Albert Hall is used - there's so much going on that it become hard to take it all…

Guess who's back, back again! If you're new to the blog series, this is where I attempt to identify all the mobile phones used by The Doctor and their companions. The 2024 series is incredible. Lots of plot, not too much exposition, and a whole bunch of mystery. I love it when Doctor Who goes off in a new direction. Let's take a look at the handsets used in these stories. The Church on Ruby…

Last week, I was part of the BarCamp London Hackathon. It had all the usual ups and downs of a Hackathon - laptops crashing, APIs failing, and HDMI ports breaking. We had a massive projector for participants to show off their work. The HDMI connection was… shit. Sorry, there's no better way to put it. It worked for about 30 seconds and then displayed a green screen. We replaced the HDMI cable. W…

As previously mentioned, I recently had a some dental issues and learned how to view a CT Scan in 3D using Linux. At a hackathon last week, my friend Sidd brought along a 3D printer. How hard is it to convert a CT scan to a file suitable for printing? Slightly trickier than I expected! Most of the guides I found were outdated, or the software didn't work on Linux, or the instructions assumed a…

Over the last few weeks, I've had several people ask me about the recent hack on the NHS. A ransomware attack has meant that several hospitals have cancelled operations and there is now an urgent demand for blood donors. What does it say about the state of NHS IT that this attack has happened? Nothing. Because the NHS was not hacked. Instead, a company they use to perform blood tests was…

The Tildagon has 2MB of RAM. That's not enough to do... well, most things you'd want to do with a computer! There's not much processing power, so running complex image decoding algorithms might be a bit beyond it. Is there a simple image format which can be parsed and displayed? Yes! The ancient Portable PixMap (PPM) format. The standard is beautiful in its simplicity. Here's the header: …

(Mostly written in response to this issue on the Awesome Falsehoods list) For those new to the format, there is a popular meme about things which computer programmers erroneously believe. This isn't intended to shame anyone - just to point out things which may not be immediately obvious to the neophyte. There's nothing us Brits love more than moaning talking about the weather. And, just as…

I'm beginning my adventures in MicroPython in the hope that I'll have something interesting working on the Tildagon Badge for EMF2026. Here's a basic implementation of a clockface. Here's how to set the time on the badge. There's a hardware clock which should keep time between reboots. Install mpremote on your computer. Connect the Tildagon to your computer using a USB-C data cable On your…

In an ideal world, people wouldn't drop litter. There would be plentiful bins and people would be responsible with their rubbish. In a slightly less ideal world, the local council would have enough money to clean up the mess left by people. But we don't live in an ideal world. People are ignorant and selfish. Councils are cash-strapped. So, once in a while, I'll go litter picking. I strap on a…

This was a bit of a labour of love - and something I wanted to get running during EMF Camp. I'm documenting in the hope it'll be useful for EMF 2026! Here's the end result: Background I'm going to assume that you have updated your badge to the latest firmware version. You will also need to install mpremote on your development machine. You should also have successfully run the basic Hello,…

Freedom of Information law is brilliant! It allows ordinary people to ask questions of the powerful and get solid answers. Sometimes these questions are sensible and journalistic. Sometimes they're vexatious. Sometimes they're a little silly. The silly ones can be fun to answer. It's a good chance for a politician to show their human side. It's pretty hard to get wrong. I mean, unless the…
