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 […]

Mastodon - the distributed social network - has two interesting challenges when it comes to how users share links. I'd like to discuss those issues and suggest a possible way forward. When you click on a link on my website which takes you to another website, your browser sends a Referer0. This says to the […]

Facebook Meta - like many other tech titans - has institutional Shiny Object Syndrome. It goes something like this: Launch a product to great fanfare Spend a few years hyping it as ✨the future✨ Stop answering emails and pull requests If you're lucky, announce that the product is abandoned but, more likely, just forget about […]

Here's a quick one-liner to reduce the precision of location stored in a photo's EXIF metadata: exiftool -c "%.2f" -TagsFromFile @ -GPSLatitude -GPSLongitude photo.jpg (Thanks to the EXIFtool Forum for their help.)

This is a real "scratch my own itch" post. I want to add Schema.org semantic metadata to the book reviews I write on my blog. This will enable "rich snippets" in search engines. There are loads of WordPress plugins which do this. But where's the fun in that?! So here's how I quickly built it […]

For many years, my email footer said "Sent via my Casio cPhone" - my attempt to poke fun at the users who hadn't updated their iPhone's default email signature. This leads to an interesting question: Marc Blank-Settle @bbcmarc on Threads@MarcSettleIs there an easy way to see what device an email is sent from? If I […]
