ortumanon Narwhal 0.7 – Rust message broker on io_uring, now with FIFO channels

0.7.0 adds FIFO channels with at-most-once delivery, alongside the existing fan-out broadcast channels. Each FIFO message is delivered to exactly one consumer, which maps naturally to work-queue style distribution: job queues, command pipelines, ordered task hand-off.

ortumanon Narwhal v0.6.0 – message broker for edge apps, now with channel persistence

hi again! i'm back with a new release of Narwhal, the lightweight message broker for edge apps i shared a while ago. the headline change in v0.6.0 is channel persistence: channels and their message history can now be durably stored on disk, so subscribers can replay missed messages after reconnecting. also swapped the async runtime from monoio to compio (still io_uring on Linux), and added first-class Prometheus metrics.

ortumanon AsyncDisplayKit – iOS framework that keeps complex user interfaces responsive

Of course it does. I admit it can take a few long to get used to it, but once you do, turns out to be kind of a mechanical process that saves you a lot of time. Above all, when combined with the interface builder. I'm quite sure those 10 min. wouldn't have been more than just 5 using IB + AL.

ortumanon AsyncDisplayKit – iOS framework that keeps complex user interfaces responsive

Awesome stuff, though it's a pity autolayout cannot be used along with this framework. Anyway, it's worth to take a look.
