Cross-Origin Storage API: Stop Downloading Twice
The Cross-Origin Storage API lets sites share one cached copy of a file (a JS library, font, or AI model) across origins by SHA-256 hash. Here's how it works.

mitmproxy - an interactive HTTPS proxy
mitmproxy is your swiss-army knife for debugging, testing, privacy measurements, and penetration testing. It can be used to intercept, inspect, modify and replay web traffic such as HTTP/1, HTTP/2, HTTP/3, WebSockets, or any other SSL/TLS-protected protocols. You can prettify and decode a variety of message types ranging from HTML to Protobuf, intercept specific messages on-the-fly, modify them before they reach their destination, and replay them to a client or server later on.
Flushes
The Internet's Bathroom. Post your flushes, see who else is in there, and keep every record in your own AT Protocol repo.

zeroserve: a zero-config web server you can script with eBPF
zeroserve is a small, fast, zero-config HTTPS server. You hand it a tarball of a website and it serves it - over HTTP/2 and TLS 1.3, with hot reload and a tiny resident footprint. The twist is that you can drop eBPF programs into the tarball and they run on every request, in userspace, as sandboxed middleware - rewriting, authenticating, and rate-limiting requests, or reverse-proxying them to a backend when you want it to act as a gateway in front of your app.

Flatpak and web browsers
You might want to provision namespace-based isolation for your browsers. But that could throw a wrench into Flatpak-based distribution. When distributing
Important piece of multi-protocol support in browsers! Thanks to much work from Javi, and funding from @ipfs.tech. HEY NOW, settle down - a ways to go: - can only redirect to URLs/paths - no Safari - off by default in Chrome (for now) - only allow-listed schemes unprefixed Step by step...

was it loaded via http+dns+ssl? then it's server-first. (which is not bad. but it's not the local-first i want.)
Jake Lazaroff
this looks very cool, i mean that genuinely, but tbh i bristle a bit seeing "local-first" used as a straw man here. of course if your server is the source of truth you can eliminate a lot of local-first complexity β the entire point of that complexity is to avoid a server-authoritative architecture!
