I've written over 3,000 blog posts throughout the years. This blog has become a repository of my thoughts, feelings, experiments, hopes, and creations. It has also become outdated, buggy, and suffers from link-rot. So, every day, I tend to my digital garden. I go in to old posts and check that the links are still pointing somewhere relevant. Are the embeds still live or do they need replacing? …

As a dedicated and professional computer scientician, I believe that all indices must start at zero. Not one, not two, but zero. The zeroth element is sacrosanct to our creed; for in the beginning there was nothing. If you're using WordPress's JetPack, it uses an ancient version of Markdown Extra. You can either monkeypatch this, or install a separate Markdown plugin. I've patched my fork of…

My name is Terence(/ˈtɛɹəns) Eden(ˈiːdən/). Modern HTML allows the user to use <ruby> to annotate text. This is usually used for furigana - which allows pronunciation to be placed above words. For example: "シン・ゴジラ (Shin Godzilla)" shows you how to pronounce both words if you are unfamiliar with kanji. The text can be any language or use any characters. In Japanese, it is quite often used to sh…

I had never seen Pertwee's final story. So I was overjoyed when an anonymous reader got it for me from my wishlist. It is an utterly bonkers story which nearly makes sense. Let's address the elephant in the room first. The "yellow face" isn't acceptable now and shouldn't have been acceptable back then. Kevin Lindsay does an "accent" which is, thankfully, mild. But would it really have been so…

Did you know that Greg Davies' BBC comedy series The Cleaner is a remake of a German comedy series called Der Tatortreiniger? Last year I compared the English episodes to their German counterparts. Only one episode was unique to the UK version - the rest were more-or-less faithful remakes. What about the new series 3? S03E01 The Reunion / S05E05 Freunde This has the same basic plot -…

Google's Android platform has dreadful support for Unicode. Even the most recent Android versions are missing out on languages, characters, and symbols which were added to Unicode in the last decade. Back in 2013, Google created the "Noto" project. Its aim? To include "all the world's languages". They wanted to banish "tofu" - the little white blocks □ which indicate a missing character - hence t…

Oooh! This is an interesting play. It is dense, wordy, and tense. It isn't a play with a frenetic pace or a huge emotional roller-coaster. It is a series of subtle arguments and twisted relationships which slowly (very slowly) reveal themselves to the audience. It is actorly - with winding speeches and hefty subtext. The leisurely pace belies the deep and dark subject matter. Although only 80 …

The problem with plays about science is that they necessarily have to give the audience a mini-lecture in the subject. The problem with biographical plays is they need to give the audience a summary of a life in a few short speeches. The problem with historical plays is they have to give a précis of the context needed to understand the times. The Lightest Element is a historical science …

Here's a "fun" thought experiment. Imagine a website which let you sign in using only your username and TOTP code. No passwords. No magic links emailed to you. No FIDO tokens. No codes via SMS. Just a TOTP generated and displayed on your device. Is that useful? Sensible? Practical? It's certainly technically possible. Store the username, store the TOTP seed, done. Your users can now log in. …

Suppose you have lots of links on a page. You want to highlight the ones which point to example.com - is that possible in CSS without using JavaScript? Yes! This scrap of code will turn all those links red: a[href^="https://example.com"] { color: red; } Now, there are a few gotchas with this code. It matches the string exactly. So https://example.com will not match…

In the early part of the 20th Century, there was a fad for "Radium". The magical, radioactive substance that glowed in the dark. The market had decided that Radium was The Next Big Thing and tried to shove it into every product. There were radioactive toys, radioactive medicines, radioactive chocolate bars, and a hundred other products. The results weren't pretty. In the early part of the 21st…

A decade ago, I appeared on the 361 Podcast to give my advice about mobile security. This was the era of the iPhone 5 and Android KitKat. BlackBerry was trying to have (yet another) resurgence and Nokia was desperately trying to keep Windows Phone alive. What advice did I give then, and is it still relevant? Stay Sceptical In at number five is just stay sceptical. I mean, quite often, lots…
