Dutch text and a diagram.

Welcome to acronym city! The Court of Appeal of Brussels has made an interesting ruling. A customer complained that their bank was spelling the customer's name incorrectly. The bank didn't have support for diacritical marks. Things like á, è, ô, ü, ç etc. Those accents are common in many languages. So it was a little…

Dear Terence, We have contacted the registry and they said they don't allow 2 successive dashes.

It's useful to share negative results. Not every experiment has an amazing or successful outcome. tl;dr you can't register Punycode .ss domains. This also means Internet users in South Sudan can't register domains using their own writing system. Background The Republic of South Sudan became independent and joined the United Nations back in 2011. A…

Lots of mechanical fingers typing on a complicated keyboard.

One of the frustrating things about computers is their limited input options. A "standard" PC keyboard only has about 100 keys. Sure, some have some bonus buttons for controlling the machine, but it is becoming clear that there simply aren't enough buttons to efficiently program computers. Most programming languages have the concept of relational operators.…

How not to sort a list of countries

A list of flags. Estonia, Spain, Finland, France, UK, Greece, Croatia, Hungary, Ireland.

Being from the United Kingdom is hard sometimes. When scrolling through a list of countries, we might be found down the bottom as "UK" or near the top as "Great Britain". Occasionally someone files us under "England" - thus ignoring Wales, Scotland, NI etc. Once in a while, it'll be "The UK". Truly, no one…

Should ₹ be part of the Latin font subset?

Some background reading. Skip if you're familiar with fonts. A font file contains a list of characters (usually letters, numbers, and punctuation) and glyphs (the drawn representation of that character). It is, of course, a lot more complicated than that. Each character has a codepoint which is represented in hexadecimal. For example, U+0057 is the…

Glowing computer text showing dot com dot info etc.

Short domains are useful for security testing. If you only have a limited number of characters, you need to be able to reference code on a remote server in as few characters as possible. A few years ago, I tried to find a Minimum Viable XSS. The conclusion that I (and others) came to is…

Steganography (/ˌstɛɡəˈnɒɡrəfi/ is the practice of concealing a file, message, image, or video within another file, message, image, or video. I recently saw someone tweeting the hashtag #ManchesُterDerby Do you see an odd character in the middle? It's an Arabic Damma (U+064F) - a vowel character.

The upper image is partially transparent. The lower image is completely opaque.

Here's a curious bug I just discovered in Firefox 67 for Linux. Can you see this unicorn: →🦄 ← What happens if you use CSS to change the opacity of an emoji? Here's a unicorn, with a pink font colour: 🦄 Unicorn Let's wrap that in this scrap of CSS to make it 50% opaque.…
