   JUring – Java bindings for io_uring file I/O▲20

   Hi HN! For the past few weeks, I've been working on bringing io_uring to Java. It started as an experiment, but slowly it became more than just that, and now trying to turn it into a proper library. After hearing talks about virtual threads and io_urings performance I wanted to build something that was faster than Java provides out of the box. I ended up creating two APIs: - A direct one that closely mirrors io_uring's behavior - A blocking one built with Virtual Threads in mind for remote files. This is the link to the project if you are interested…

    Peeng – like Pingdom, but the other way around and simpler▲84

    Hey folks! Shahar and Tal from Keep (https:&#x2F;&#x2F;www.keephq.dev) here! For the last few weeks we’ve been building Peeng and can now share our beta with you: https:&#x2F;&#x2F;www.peeng.sh. Peeng is the easiest and quickest “heartbeat” architecture we could think of. Just pick a subdomain (e.g. x.peeng.sh), configure an interval, an endpoint, and a payload, and hit that subdomain every <X (interval) seconds — If you won’t, Peeng will send an HTTP POST request to your configured endpoint. It’s Pingdom&#x2F;Cronitor&#x2F;heartbeat.sh free alternative (but the other way around and A LOT…

    Ayder – HTTP-native durable event log written in C (curl as client)▲56

    Hi HN, I built Ayder — a single-binary, HTTP-native durable event log written in C. The wedge is simple: curl is the client (no JVM, no ZooKeeper, no thick client libs). There’s a 2-minute demo that starts with an unclean SIGKILL, then restarts and verifies offsets + data are still there. Numbers (3-node Raft, real network, sync-majority writes, 64B payload): ~50K msg&#x2F;s sustained (wrk2 @ 50K req&#x2F;s), client P99 ~3.46ms. Crash recovery after SIGKILL is ~40–50s with ~8M offsets. Repo link has the video, benchmarks, and quick start. I’m looking for a few early design partners (any…
