HardenedBSD Is Now Officially on Radicle

the fact that you, as the creator of a "competitor", post this as-is without a "At $co, we…" run-on is a good look

Oh, that's pretty cool! Now I can't decide whether that approach or one based on AT is better...

Pick whichever. We <3 the Radicle team and they're admittedly solving a much harder problem (gossiping git!) and rather elegantly at that.

Yeah I’ve met the Radicle people a couple times. I’ve never given it a thorough review but, for their goals, their designs have always seemed strong, and they’re pleasant people to chat with.

The main difference was atproto wanted to tackle scale, so we went with a servers & aggregation model. Radicle is going for device-to-device networking as a primary goal.

Do you think it will be possible to use them together? Having some sort of unified distributed system is intriguing to me. (e.g. can the Radical foundation and AT-proto foundation integrate, even?)
