I’m interested in HTML, CSS, and making the web less annoying. My name is pronounced ˈshe-meh.

Idea for 2-in-1 chart:

black part = full chart with non-truncated y-axis; useful for observing the real yearly change

red part = zoom in on the same data; effectively the same as if the y-axis were truncated; useful for observing the trend

Firefox 150 just landed & includes new web platform features like:

🎉 sizes="auto" on images
🎉 light-dark() image support
🎉 CSS revert-rule
🎉 ariaNotify()
🎉 Media pseudo-classes like :playing

None of these are baseline yet, so check MDN for support.

So when we ask, What time is it?, we’re asking about the time, but when we ask, What is the time like?, we’re asking about the weather, got it?

And when we ask, At what time did you arrive?, we’re asking about the time, but when we ask, At what kind of time did you arrive?, we’re asking about the weather.

I just realized that the Croatian language does not have a separate word for “weather”. We just reuse the word “time”.

So a weather forecast is called a time forecast. Instead of severe weather, we say severe time. When we talk about weather conditions, we say time conditions.

Crazy, huh? I was thinking about weather, and I couldn’t think of a Croatian word for it. But I thought, there must be something because it’s such an important concept that needs its own word. Turns out, no, it doesn’t.

TIL: There is no atomic structure inside black holes. Electrons, protons, and neutrons get crushed together.

The grays and blacks

gray economy = informal economy/sector, shadow economy, undeclared/unregulated economic activity

“black work“ (Schwarzarbeit in German) = undeclared work activity

gray market = e.g. unlicensed reselling of legal goods
black market = e.g. selling of illegal goods

I’m trying out a new approach to reading the news where I first read the AI-generated summary of a news article and only then the news article itself.

Some problems of news articles:

* too much text, very verbose, critical information is intertwined with relatively unimportant information
* generally confusing to read, obscure words
* sensationalist and manipulative writing, especially in the title and first few paragraphs

The AI summary gives me a good introductory overview. It’s helpful.

Q1 2026 was a very strong quarter for Firefox Security & Privacy.

some highlights:
- We expanded AI-assisted vulnerability discovery through our collaboration with Anthropic, helping identify and fix a high number of real security issues.
- We shipped the Sanitizer API in Firefox 148, making Firefox the first browser to support this stronger defense against XSS.
