We have a black hole at home — with actual relativistic physics, live in your browser. I'm Sasha (Alexander) Plavin, an astrophysicist at Harvard's Black Hole Initiative studying quasars and black hole environments. I work with raytracing/radiative transfer simulations professionally, and wanted to make one anyone can play with — so I built this app. Put the black hole onto your screen (any browser), or directly into your room with AR or VR (requires WebXR, for example Chrome on Android, or any

Imagine you are the parent of an inquisitive seven-year-old who loves his family, playing baseball, and hanging out with his friends. It's the life you've always wanted. And then the worst thing that ever could happen happens: A freak accident takes your son away. But as it turns out, you don't have to live with […]

Hi all, So I have been working on document layout analysis for some time now. I have tried the models like Doclayout, Docling, Miner U, marker. I am working with Journals. Overall Docling performs well, but the problem is that it over performs. And mineru u misses some content like the corresponding author on the page-footer. And it is also missing the masthead mark, and the article-type label. In my opinion unlimited OCR performs well in all the tasks, but in general it is failing to recognise any style at all. And it is bad at recognising logos. So I am wondering are there any state of the art models (SOTA) that are good at PDF text extraction and layout extraction ?

You've probably seen this: Kubernetes probes are green, /health returns 200, CPU isn't on fire - and users are timing out. Process is up. Just not doing anything useful. Classic event loop freeze. Something sync and expensive (or a dumb busy loop) grabs the thread, and suddenly timers, HTTP, DB callbacks - all of it waits. Including your health endpoint, because that also needs the loop. monitorEventLoopDelay() is fine for dashboards. It won't yell at you while the process is stuck, and it definitely won't write a log line from outside the frozen loop. That's the part that annoyed me enough to build this. I made @js-ak/watchdog - tiny N-API addon. The monitor runs in C++ on its own thread and writes JSON lines to stderr/file even while the JS event loop is stuck. Your freeze / recovered handlers only run after the loop unblocks. Optional RSS/CPU, optional stack sample. npm install @js-ak/watchdog const watchdog = require("@js-ak/watchdog"); watchdog.on("freeze", (e) => console.log(e.event, e.duration_ms)); watchdog.on("recovered", (e) => console.log("back after", e.duration_ms, "ms")); watchdog.start({ freezeThresholdMs: 1000, logTarget: "stderr", // or "file" | "both" source: "payments-api", }); Real freezes usually aren't while (true) . More like giant JSON.parse, a cursed regex, sync crypto/compress, or some dependency doing sync I/O on a hot path. Stuff you only notice after people complain. Prebuilds for the usual platforms (Node 22+). MIT. Repo: https://github.com/JS-AK/watchdog Curious how other people catch loop stalls in prod - and what you'd actually want in the freeze payload. Roast the API if it's wrong.
