The Mobile Phones of Doctor Who - Bonus Pyramid at the End of the World. And a sneak peek...

· 3 comments · 450 words · Viewed ~252 times


General talking on a sat phone.

If you're a Doctor Who fan, this post contains a lovely little surprise at the end. I promise you it'll be worth it. For a few years now, I've been running a blog series about the Mobile Phones of Doctor Who. I'm only human, so I occasionally miss some of the devices. A reader contacted me to say I'd missed three phones from the Series 10 episode Pyramid at the End of the World. Firstly, a…

Why don't we just eat grass?

Photo of a glass of milk and some cheese in a field of grass.

I read an interesting discussion the other day about why humans (mostly) don't eat carnivorous mammals. It boiled down to a few main points: Carnivores often don't taste good due to their relative lack of fat and stringy muscles. Aggressive animals are hard to domesticate. What do you feed them? 1 and 2 are manageable. A few centuries of selective breeding and I'm sure you'll have a…

Can this new probiotic reduce lactose intolerance?

A small pharmaceutical bottle. It easily fits in my hand.

I ordered some pills off the Internet and swallowed them! What could possibly go wrong? Let's get one thing out of the way first. I am not a doctor. I don't even play one on TV. This blog post is not medical advice. (more…) …

Book Review: Pod - Laline Paull

· 200 words


Book cover showing a swirling mass of dolphins.

After reading Laline Paull's The Bees, I was eager to read her next work. The Bees was about Bees, obviously. Pod is about a pod of dolphins - and their oceanic friends and society. Weirdly, this is the third book I've read from the perspective of cetaceans. Both The Idiot Gods and Startide Rising deal with similar themes - how to represent the complex world of sea creatures into sometime…

Movie Review: Don't Worry Darling

Movie poster.

This film is a masterpiece. Sure, the plot is nothing special ("What is the dark secret behind this seemingly idyllic life?!?) but it is directed with such flare and texture that it becomes a joy to watch. I can't remember when I last saw something which kept me engrossed just through the sheer inventiveness of its design. I love going into movies without knowing anything about them. I'd seen…

Restaurant Review: 3D Printed Redefine Meat @ Unity Diner

Inside of the fake steak. It looks stringy, just like real meat.

"How long have you been vegetarian?" Asked the waitress. "Oh, over twenty years now," I replied. She looked concerned. "Some people find the 3D printed steak a bit..." she paused, considered, and continued, "A bit intense. It takes people by surprise how it makes them feel. I enjoyed it, but I'm not sure I'd eat it again." With that, she swept off with our cocktail orders. Unity Diner is a…

The absurdity of technocracy

Screenshot of a scan of newsprint.

Punch was a satirical magazine first published in Victorian London. It had a long and noble history of poking fun at... well, just about every fashionable idea of the day. Anyone who pricked the public's conscious probably found themselves lampooned within its pages. Charles Babbage - inventor of the first mechanical computer - found himself starring in a few articles. Here's a scan of one…

Book Review: 12 Bytes - How Artificial Intelligence Will Change the Way We Live and Love by Jeanette Winterson

· 250 words


Book cover.

Hmmm... I was left a bit unconvinced by this series of essays. They feel like casually written blog posts - or hastily dashed-off Sunday Supplement articles. I was expecting a bit more rigour and investigation. The book treads over well-worn ground - most Silicon Valley companies are trying to recreate Mommy tidying their room via AI, Uber is trying to eat the world, algorithms leave us in…

Unicode operators for semantically correct programming

· 29 comments · 100 words · Viewed ~483 times


Why do most programming languages use the / character when we have a perfectly good ÷ symbol? Similarly, why use != instead of ≠? Or => rather than →? The obvious answer is that the humble keyboard usually only has around 100 keys - and most humans have a hard time remembering where thousands of alternate characters are. Some programming fonts attempt to get around this with ligatures. That all…

OpenBenches at GeoMob London

Liz and Terence standing in a lecture theatre, presenting their work.

Last week, Liz and I had the great pleasure of speaking at GeoMob London - a meet-up for digital geography nerds. We gave a talk about OpenBenches and how far it has come since launch. It blows our minds that we've have over TWENTY-SIX THOUSAND unique benches added to the site. And it is a little daunting to host nearly a quarter of a terabyte of photos from around the world. We got lots of…

How I became the #1 mapper in New Zealand

· 6 comments · 350 words · Viewed ~941 times


Screenshot showing that in the last 7 days I was the number 1 mapper in New Zealand the 42nd in the world.

I hate leaderboards. I think competition tends to corrupt the incentives people have to contribute to a goal. Yet, at the same time, I was delighted to see that I was the top mapper in the whole of Aotearoa New Zealand. For one specific week in December. They say golf is a good walk spoiled. StreetComplete is a good walk enhanced with sidequests. As you wander around, it asks you little…

Book Review: If It's Smart, It's Vulnerable - Mikko Hyppönen

· 1 comment · 400 words


Book cover. The author's photo is distorted by electronic interference.

This is a curious book. It starts out as a look at the security of everyday objects, but quickly becomes a series of after-dinner anecdotes about various security related issues. That's not a bad thing, as such, but a little different from what I was expecting. There's no doubt that Mikko walks the walk as well as talking the talk. Almost every page contains a bon mot. For example: Working in …
