Supertoys last all summer long! But batteries do not. The last set of rechargeable batteries I had leaked everywhere, and I could never find the right charging lead for the gizmo which pumped power into them. So let's cut out the middle-man and plug a USB-C cable straight into our batteries! What? These were the cheapest AA batteries I could find which took USB-C. £16 including delivery, for …

I love my solar panels. But the solar panels don't love the British midwinter. Most of the year, my panels produce more electricity than I can use. But in winter we're lucky if they produce 3kWh per day - and most of the time it is considerably less. So our winter electricity bills must be massive, right? Nope. The normal cost per kWh is 28.5p (including VAT). We're paying less than half that …

(This is, I think, a silly idea. But sometimes the silliest things lead to unexpected results.) The text of Shakespeare's Romeo and Juliet is about 146,000 characters long. Thanks to the English language, each character can be represented by a single byte. So a plain Unicode text file of the play is about 142KB. In Adventures With Compression, JamesG discusses a competition to compress text…

About a million years ago, I took a cute girl on a date to see the cult movie Lola Rennt. I felt pretty cool for knowing all about hip German cinema. I eventually married the girl, so she must also have thought I was pretty cool. Well, a few days ago, I found out that Netflix remade the film last year. In Hindi! Looop Lapeta (লুপ লাপেটা - literally "Crazy Situation Looping") is a hyper-modern up…

Look, here's the deal. Sometimes companies send me products to review. I usually try and make sure they're interesting, useful, or delightfully weird. Mostly they're electronic gadgets or cool books. But someone offered to send me a shower head to review. And our old shower head had got a bit gunked up. So I said yes. I have sold the soul of this blog for a £13 bit of plastic full of magic …

This is a retropost. It was written contemporaneously in 2019 - but posted in 2024. I had just been seconded to the Department of Health and Social Care to help kick-start NHSX. I kept a diary of my time there - including working through COVID. As it has been 5 years, and I no longer work in Government, I thought I would publish interesting extracts from it. My 4th day in a new job and I'm sat…

A week is a long time in politics and a couple of years is an aeon in AI. Published in 2019, just before the dawn of the LLM, this is an overview of all the weird and charming ways Artificial Intelligence can go wrong. It is fully of delightfully silly examples and rather charming illustrations. Lots of the examples are drawn from the always-entertaining AI Weirdness blog. But it does suffer…

Whenever you talk about renewable energy, it's impossible to avoid a very particular strain of reply-guy. The "Nuclear is really good actually" dude is convinced that you have critically misunderstood Our-Lord-And-Saviour Uranium. Nukes are clean! They are cheap! They are safe and healthy! They are brilliant! Nuclear power will save us all! Look, I 100% agree that nuclear power is…

I'm a sucker for anything Star Wars. So when my Oculus Quest told me I could fight Darth Vader in VR, I leapt at the chance. I kinda wish I hadn't bothered. There is very little "game" here. It's barely an interactive movie. Walk forward until you step on a trigger, watch a very slow cut scene, wave your arms until something happens, repeat a few times, roll credits. That's it. There's nothing …

Ach. This is a hard one to give a lower review score to. I loved MRK's Lady Astronaut series - but this crime-thriller fell a little short of the mark for me. Part of the problem with setting a whodunnit in the future is that you have to assume criminal detection technology gets better. That means an author has to find a way to nobble cameras with privacy force-fields and bypass biometric…

There are lots of new image compression formats out there. They excel at taking large, complex pictures and algorithmically reducing them to smaller file sizes. All of the comparisons I've seen show how good they are at squashing down big files. I wanted to go the other way. How good are modern codecs at dealing with tiny files? Using GIMP, I created an image which was a single white pixel,…

I'm loving the fact that BBC iPlayer has all the classic Who stories available to stream. I've been dipping in and out of the ones I don't have in my DVD collection. Paradise Towers is a brilliant story. It is well directed (which makes a nice change) and the story actually makes sense (mostly). The set decoration and story elements directly influence the modern series. And - most importantly of …
