Jeremy's whole post is worth a read, and I would underline + bold the last point: the web is the superior choice for privacy and security, and it's anti-web *and anti-user* to be preferencing native app install affordances: adactio.com/journal/22757

If you're dealing with SVG icons you probably know the pain of overwriting colors. There's a new spec in the making that allows controlling CSS variables from "the outside". And it's shipping in Firefox already! drafts.csswg.org...

Code snippet: img { link-parameters: param(--color, green); } and .foo { background-image: url("image.svg", param(--color, green)); }

Is it the wine talking, or does anyone else recall that sites early to adopting HTTP/2 websites *felt* different to those stuck on 1.1? We had no Core Web Vitals back then, but I swear I could sense that vertical waterfall before even opening DevTools.

On February 28, the #Internet was shut down in #Iran for the second time in 2026. Two months later, it remains largely unavailable. However, increased allowlisting of external sites, and availability of "Internet Pro" access has driven nominal increases in traffic visible in the back half of April.
