A pet cat typing on a computer keyboard.

Picture the scene. You're in a pub and order, say, a cider or a cocktail. The local pub bore pipes up "What are you drinking that for? Real men drink..." and then names a brand of generic, piss-weak lager that is his substitute for a personality. He's the same guy who insists that "real men" watch football, and can't quite believe that you have no opinion on last night's cup final. This sort of …

Some giant question marks standing in a field. Photo by https://www.flickr.com/photos/dbrekke/181939582/

During my (brief) stint teaching senior leaders about AI, there was one question that I urged them to learn above all others. What is the acceptable failure rate? For this, I had to teach them two concepts. False Positives. For example, telling someone they have cancer when they don't. False Negatives. For example, telling someone they don't have cancer when they do. There is a cost…

What would a decentralised Uber look like?

Photo of the inside of a Hong Kong taxi. There are about a dozen different phones attached to the dashboard - each running a different app.

Uber are undoubtedly a company engaged in extremely dodgy activity. But, on the other had, they're ridiculously convenient. A few months ago, we landed in a foreign country, opened the same Uber app as we used back home, and booked a cab. It just worked. I didn't need to register for a different version. I didn't need to create a new account. I didn't need to add a new credit card. That's the…

Tech Predictions for 2023

A plasma ball glowing with ethereal light.

Only fools try to predict the future. You can read my earlier predictions, or dig deep into my archives and rate me on how foolish I am. I tend to look at technology through the lens of "what do I want to happen?" and then assume the worst. So, here goes! Federation Gets Simpler As I wrote about in The Social Pendulum we see a swing to extremes of culture. We've had a decade-or-so of big…

Book Review: Rising Tide (Lauren Fraser mysteries Book 2) - Jennifer Palgrave

· 150 words


Crashing waves on the shore make up this book cover.

Nat Spiller, an admired climate change activist, has accidentally drowned. That’s the police verdict. But was it an accident? His partner Ellie thinks otherwise. Pam, Ellie’s aunt, draws a reluctant Lauren Fraser into the mystery. It's a bit weird to describe a murder mystery as "cosy" - but that's the vibe of this book. It's a sequel to The One That Got Away and follows a similar template. Th…

Naming things is hard - DNS for the Federated Web

The multicoloured interlocking lines of the Fediverse logo.

How should I design my personal DNS for all the cool new Federated Services and IndieWeb protocols? Way back in the early 2000s, I started this website - shkspr.mobi. A few years later, I added a blog. I could have used the main domain, or created a subdomain like blog.shkspr.mobi. In the end, I chose a subdirectory of shkspr.mobi/blog I don't know if that was the right choice back then, but…

Gadget Review: Meta Quest 2 replacement headstrap

· 200 words


A VR headset strap with lots of questions.

The headstrap which ships with the Meta Quest 2 is shit. It is a cheap piece of fabric, held together with velcro. It's fiddly to adust and uncomfortable to use for longer than a few minutes. Zuckerberg likes causing you pain. So I purchased the cheapest upgrade strap I could find - £15 on special offer. It has a forehead cushion, which reduces pressure on the face. The tightness is …

Graph showing all forms of worship steadily decreasing.

The Church of England publishes statistics about the numbers of its faithful. These are particularly interesting in light of the recent news that the UK no-longer has a Christian majority. The CofE's statistics are for 2019 - before COVID messed up everything - and I think offer a fascinating glimpse into its future. The two figures which struck me were: 89,000 baptisms during 2019 114,000…

Zeno's Paradox and Why Modern Technology is Rubbish

Robot faced Mark Zuckerberg is wearing a VR headset - it digs painfully into his smiling cheeks.

Amazon Alexa is losing billions of dollars. Self Driving Cars are losing billions of dollars. The Metaverse is losing billions of dollars. Are we about to witness the biggest crash in technological progress? I'm particularly fond of the Rule of Credibility which states: The first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the …

A tiny black and white image of a boy on a telephone.

Way back in the mists of time, I did my secondary-school work experience at the BBC. Specifically, Children's BBC. Every day for a couple of weeks, I'd commute into White City, wander those hallowed halls, sit at a desk, and... You know... I can't remember! I know I got to visit the "Broom Cupboard", and I'm pretty sure I did a lot of data entry, oh - and I sat in a meeting for "Two-Way TV". …

How Blockbuster was superior to Netflix

A giant red letter N. The Netflix logo.

It's a Friday night in the late 1990s and my teenaged friend group are bored. We're not cool enough to hang about in the park drinking cider. And we're not nerdy enough to play D&D. We don't have enough money to go to the cinema. What we do have is a Blockbuster card and, between us, just enough cash to rent a newly released movie. Eight of us pile into the local Blockbuster and begin to…
