I've often heard that Netscape 3 couldn't handle self-closing tags when the closing slash directly followed the tag name, that's why people started adding a space before the slash (e.g., <br />). But I've never found any official source—documentation or a bug report

I never paid attention to this before, but now it's going to haunt me for the rest of my life.

the javascript Date class is so advanced

Last week, I was experimenting with void elements, and...what the heck is happening there?

This is insanity

Determining if a given HTML tag is a void element:

Even though C23 enforces two's complement, it still leaves the bitwise right shift of a negative number implementation-defined 🤔

DNS started as a text file on Jon’s computer. To register a new domain you would email Jon.

Funnily enough, on my GNOME Debian, the ㎬ character is rendered as "GPA" (with a capital A), while I'm pretty sure it should be GPa. Could this be a small mistake of the Cantarell font?

every day i join zoom calls and talk about regexes

Lately I've been digging into JS normalization issues, and I was wondering about the options we have to do case folding in JavaScript. For full case folding, it seems like str.toLowerCase().toUpperCase().toLowerCase() does the job? Can it really be that simple?

We’re rapidly reaching peak birdsong, as breeding season is in full swing and resident birds are being joined by migrants, so maybe now’s a good time to be reminded of the existence of the Swedish word ‘gökotta’ – getting up early to listen to birdsong.

If you're interested in progressive enhancement web design at all, you may have encountered situations where you only want to render something when JS is enabled. Maybe a button to control a menu, or a theme switcher icon. Well I wrote about how I solved that problem today. 0xda.de/blog/2025/04...

Dans les archives du premier avril, on a un certain Oliver Bickar qui en 1974 qui a mis le feu à des milliers de pneus qu'il amenait depuis 4 ans dans le cratère du mont Edgecumbe en Alaska pour faire croire aux habitants de la ville de Sitka que le volcan etait en éruption

I totally agree. Or at least I used to. Recent facts I came across while re-reading parts of @rcs.bsky.social's "Effective C" - the book that reminds you that the "C" in "C Programming Language" stands for "Cthulhu" - made me revise my mental model a little bit

#TIL l'expression « et des ratons laveurs », ajoutée ironiquement à la fin d'une énumération dont le contenu hétéroclite semble improbable. L'expression est issue du poème « Inventaire » de Jacques Prévert, écrit en 1957

Fell in love with ESLint's AST selectors. So declarative and powerful! Having this out of the box in Deno is huge. I used to test my selectors at eslint.org/play/ by adding them to the no-restricted-syntax rule. I wonder if there is an easier way to do this?

This symbol only exists because of a 2007 Unicode misinterpretation of a 15th century Old Church Slavonic manuscript in which the author decided that the O in "many-eyed seraphim" needed to reflect the many eyes of the seraphim. This is a glitch angel.
