The question which could bring down the government

Terence Eden standing outside Number 10 Downing Street.

This is a retropost. Written contemporaneously in May 2020 during the height of the pandemic, but published long after the events. The day the EU referendum was announced, the then Prime Minister came to visit our office. We were given a chance to talk to him in front of TV cameras. This was my chance. I could ask a question - the perfect question - which would win the referendum and bring down …

Is it rude to make a profit from your friends?

Lots of blinking stickers next to each other.

You're in a restaurant with a group of friends. The waiter won't let you split the bill, so you offer to pay for it on your card and have your friends send you their share. How much would you charge them for that service? That sounds absurd, right? OK, you might agree to split the bill evenly and maybe come out one drink in profit - but it's still a bit of a social faux pas to deliberately make …

Book Review: Understanding Privacy - Heather Burns

· 1 comment · 400 words


Book cover for Understanding Privacy.

Heather Burns has an absolutely deft way of turning the sometimes-dull world of digital privacy into entertaining, informative, and actionable prose. Too many of these sorts of books end up being a list of woes and end with "someone should do something, I guess?". Understanding Privacy is different. All the way through the mantra is "You are someone! You do something! And here's how..." …

The Telegraph is wrong about FIRE

A tiny lego Storm Trooper eats a chocolate coin.

Everyone's favourite tabloid, The Daily Telegraph, contains an article decrying the Financial Independence Retire Early philosophy I have a mixed relationship with the FIRE movement. It basically boils down to "spend less, save more, then you can retire once you've save 25x your annual spend". That's it. As Michael Taylor writes, some people fetishise the "spend less" part. If you deny…

A security bug caused by… Dark Mode!

Image is of a Green Shield with a white tick.

Everyone loves Dark Mode. It is kinder on the eyes, less energy intensive, and looks hecking cool. *5 seconds later* We regret to inform you that Dark Mode causes security bugs. (With apologies to Ben Ward) OK, OK. This isn't a particularly severe security bug, but I found it interesting. The Matrix messaging app "Element" lets you sign in to your account on multiple devices. In order to…

Gell-Mann Amnesia and Purdah

A t-shirt which says Dunning and Kruger and Gell and Mann.

This is a retropost. Written contemporaneously, but published long after the events. At the time, I was a Civil Servant in Cabinet Office. Now I am not. But as we're heading for another General Election, I thought I'd share this post. It's the evening of the 2019 General Election. I am plagued by two thoughts. Briefly stated, the Gell-Mann Amnesia effect works as follows. You open the…

Uhura, a black lady, is kissing Kirk, a white man.

Once in a while, you'll see some blowhard railing about the modern world. I recently saw someone decrying the fact that Star Trek had "gone woke". This Star Trek? OK, you can argue about whether Kirk and Uhura were forced to kiss in that episode. But how does anyone look at Star Trek - with its women on the command bridge, anti-colonial stance, and mixed-race crew - and not think it was a…

Why do people focus on AI's failures?

A robot with a backlit human face.

I saw a prominent AI proponent asking why people always focus on the things that AI gets wrong. AI works so well, he asserted, that it was churlish and childish to focus on a few minor mistakes? Which reminds me of an experience I had a few years ago. I was in a rural pub and got chatting to one of the locals. We were getting on great, so I asked him what his name was. "You know," he said,…

It isn't who you know - it's who knows you

A pet cat typing on a computer keyboard.

I'm terrible at networking. I forget people's names minutes after meeting them, I never have business cards and lose the ones I'm given, and I can't go five minutes without burbling some nonsense. But I recognise that networking is a skill and, like any skill, it takes practice to succeed. I've always been told that success isn't always about what you know, but more about who you know. So how…

Selfie of me and Liz. I am being strangled by Darth Vader.

I've got about another 10 months left at my current job and after that... I don't know what I'll do. I've already moved down to 4 days a week in an effort to glide down to FIRE. Do I really want to go back up to 5 days? Could I find somewhere that would be happy with me doing 3 days? Can I be arsed to constantly hustle for ad-hoc client work? Can't I just stop? What would happen if I took a…

Book Review: Red Side Story - Jasper Fforde

· 2 comments · 250 words


Book cover - a red land with a spoon in the foreground.

Fourteen years ago, I read Fforde's Shades of Grey and my life hasn't been quite the same since. It was a magical tale, almost totally devoid of exposition, building in an fantasy world like no other. Fans have been clamouring for a sequel ever since. The first few chapters of the sequel do an excellent job of exposition - but this isn't the sort of book you can pick up without having recently…

Accents and eBooks

The phrase "Swords of Qadisiyyah." But the combining macron over the letter "a" has been rendered as a separate dash.

By and large, the English language doesn't use diacritical marks. Even our loanwords are stripped of them; we drink in a cafe rather than the more pretentious café. This has a consequence for HTML and, by extension, eBooks. As a quick primer, modern computing gives us two main ways of displaying a letter with an accent. The first is simple - encode every single accented letter as a separate …
