Aaargh! My name _does_ contain only letters. #stupid

A user interface element showing a form input field for "First Name" containing the text "Michaël" with an accompanying error message "First name can contain only letters".

I wrote some PHP code in 2004 mimicking Explorer's grouping feature; it has also nice support for future file dates. Found an interesting bug at that time as well. 🫣

A screenshot of code defining two arrays: one for "Size Groups" with numeric keys mapping to size descriptions (Zero, Tiny, Small, Medium, Large, Huge, Gigantic, Folders), and another for "Date Groups" with string keys mapping to time descriptions (Today, Yesterday, Last Week, Two weeks ago, Last month, Two months ago, Last year, Two years ago, Tomorrow, Two days from now, Next week, Next month, Next year, Two years from now, Sometime this millenia). There's a comment in the "Date Groups" array mentioning a bug in Windows XP related to grouping files by date.

A big thanks to @was.tl for another fun start of december with a bit of sleep deprivation. 🥱 For me, #AdventOfCode is all about competition, if only with myself and BenchmarkDotNet. 🚀 I know, there is still room for improvement...

Today I climbed to the top of the 1984 olympic ski jump slope in Sarajevo. Quite a view!

Hey @dylanbeatt.ie, For the list of obscure CSS constructs: text-decoration-color, color-mix(), currentColor, and text-underline-offset Did you already use color-mix() to create blue? 😅

Screenshot of CSS code in a developer console showing different link styles. The styles define hover effects, text-decoration settings, and color mixing using color-mix, currentColor, and CSS variables like --color-accent and --color-primary. Several properties are struck through, indicating overrides by more specific rules.
