TIL: relative colours in #CSS. You define an origin colour, and then modify (with the magic r/g/b/alpha variables for rgb) or override the values. Supported in all major browsers now (except Firefox for Android): https://caniuse.com/css-relative-colors
Example: Use the primary colour, but make it transparent and reduce how green it is:
rgb(from var(--primary-colour) r calc(g/2) b / calc(alpha * 0.5))
Related: Is there something like a caniuse.com newsfeed that tells me when a feature has become supported by all major browsers (or, ideally, supported by major browsers for a month, half a year, a year …)?
Imagine if web.dev, the web development blog by the Chrome team, had the latest coolest tech like … RSS feeds for their blog. Then you could just subscribe to https://web.dev/series/baseline-newly-available and get notified about newly availble CSS features …
(To add insult to injury, they load their list of blog posts via JS, so you can't even point a good feed reader at the /blog/ page and have it scrape for new posts. Eww.)
The Tunnel of Eupalinos was built in the 6th century BCE in Greece. It's just over 1km long, goes through a mountain, and was built from both sides.
And! It was built as an aqueduct, so it has two parts; a footpath and a lower water channel. It was in use for a thousand years before the channel silted over.
Recommend to block activitypub-proxy.cf. It's running software designed solely to evade blocks.
The software is based on subdomains – Mastodon blocks subdomains automatically (edit: when you block the main domain), but if you're running different software, you might want to double-check.
