Rust, CBOR, DASL/ATProtocol, iroh, quic/webtransport, and webrtc are all at the top of my list of production tech these days. They are the starting points.

Still holding out for enough WebTransport uptake that we can get unreliable networking in the browser without webrtc insanity.

Someone should do a tier list video of all of these proposals.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

TIL about WebTransport serverCertificateHash. But where do websites get the hash from if it can't talk to the device in the first place? ;) Are people relying on a rendezvous server on the internet where the local device needs to register its public key/hash? And what would TOFU look like here?

webrtc SHOULD ditch the massive security risk / general un-governability / ancientness of using SCTP in general and update, get on webtransport ASAP.

So there’s a new streaming protocol being standardized that can do sub-second latency from OBS to a browser, no proprietary infra required. It’s called Media over QUIC (aka "MoQ"). I work on it, and I started a newsletter about it. Issue #0: buttondown.com/moqmonthly/archive/moq-monthly-0/

What would you call the group of JavaScript APIs containing XMLHttpRequest, fetch, WebSocket, WebTransport, and EventSource?
Ten years ago I'd call that "Ajax" but I'm not sure anyone really uses that term anymore.
"JavaScript networking" seems overly vague?
