I smell quite some FUD about the alleged Signal 0day.

The recommendation is to turn off link previews, however link previews are generated on the sender side. Just tested, with link previews turned off you’ll still receive them from a device that sends those.

I think this would mean either:

  • Turning off link previews isn’t a sufficient mitigation

or

  • The vuln is triggering on the sender side that means someone needs to convince you to create a message containing a malicious link

or

  • The whole thing is fake and just a nice troll

Introducing Bark! Low-latency multi-receiver live-sync lossless audio streaming for local networks. It's like Sonos, but open source, so nobody can brick your devices remotely. It's also written in Rust :)

github.com/haileys/bark

It sends 48khz uncompressed float32 data over UDP multicast. It can achieve playback sync to within hundreds of microseconds in ideal conditions, and usually to within a millisecond.

I've been working on it in my spare time over the past week, and I'm pretty happy with how it's shaped up. I have three receivers setup and it works remarkably well at keeping everything in sync as I walk around my house. For now it only really works on Linux, and supports Pipewire (and Pulse in theory), but there's no huge impediment to making it truly cross-platform.

It also features a fancy live stats subcommand, which can used on any computer in the same multicast domain to watch the status of the stream cluster:

 A screenshot of the `bark stats` command on my local network. The command reads from ~/.config/bark.toml, and then shows each node in the cluster. There are three receivers, and they are all fairly in-sync with each other, all within a millisecond. There's some other stats too, showing how much audio is in the buffers, the network latency, and the clock prediction offset.
