This article is pretty fun. I'd solve it with a bunch of stacked links, then have a registered custom property that uses random() to set an int between 0 and number-of-links, then use that in an if() function to display:block one link (matching the randomly chosen int) master.dev/blog/a-butto...

A Button That Links to a Random Post in HTML & CSS Only

Perhaps this theoretical button wasn't a button at all, but 50 links in a trenchcoat.

Building a paid browser for developers by yourself is a huge uphill battle every day. But some days you open the state of CSS survey results and see "I use Arc as my primary browser but Polypane is goated for development." as the first comment ❤️ 2026.stateofcss.com/en-US/other-...

it is unbelievable how hard ubuntu and friends have been shooting themselves in the foot with snap and flatpaks 'security' systems.

A horror story in six words.

I caved and finally got a new phone. I definitely miss the iphone mini form factor (bring it back), but damn is it nice to end the day with 81% battery left rather than having needed to charge it twice.

Remember these? Well, we made them available online using some fun CSS transitions, and we made them available as free print-ready downloads too! Go play with them here: polypane.app/cheatsheets/

It happened. My propensity to respond to support and onboarding emails quickly is being perceived as AI. Do I: - Delay responding for two business days to match other companies slowness? - Intentionally add typso? - Attach a photo of me with a shoe on my head to each reply?

My favorite part of reporting well-defined and clear browser bugs is when they get ignored for years and then discarded. issues.chromium.org/issues/34897...

I hate these type of slop dumps, but what I hate more is the massive wall of text they want me to read. You couldn't be bothered to write it, I'm not going to bother reading it. If you open a PR with a slopwall, I'll close it regardless of merit. github.com/Kilian/elect...

The thing with people asking for refund to a subscription they created a month ago (and used) is that i'm fucked either way: I say yes, you got to use it for free I say no, you chargeback, I lose the money anyway + an additional €20 fee I can cite EU law till I'm red in the face, AMEX doesn't care

They announced zero speakers. 15 tickets left. If that doesn't speak to the quality of this conference I don't know what does. See you there.

If your extension has a configuration page that same page is called... "Options" in Chromium "Preferences" in Firefox "Settings" in Safari. This bothers me.

In a shocking reversal of roles, the latest update to the Polypane browser extension helper has been reviewed (and accepted) by every store except the Chrome Web Store.

My own pet theory is that the unfettered algorithmisation of everything is to blame. I think it should be treated like the gambling it is. Social media for <16 should be allowed, but they should only be allowed to offer you the gambling aspect of recommendation algos at 18+

Interesting read on the what and why of the decline of play/anxiety in kids but it feels like everyone in the article is just philosophising about it rather than touching on anything real. "What if It’s Not the Phones? - The Atlantic" archive.ph/uIcCC

why is everything about apple's publishing systems so dumb.

Discussion kind of died down, but someone added an "Agenda+" badge to it. Any CSS WG people that can tell me what that means? :D

I think that `random-item()`, once implemented, would be even better if it had weighted values. So I made an issue making the case for it. Let me know what you think! (Hey @joshtumath.uk look at me doing a CSS WG thing!) github.com/w3c/csswg-dr...
