I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/

Hi, I am David Kircos. The Founder of Quadratic (https://QuadraticHQ.com), an open-source spreadsheet application that supports Python, SQL (coming soon), AI Prompts, and classic Formulas. Unlike other spreadsheets, Quadratic has an infinite canvas (like Figma). As a result, you can pinch and zoom to navigate large data sets, and everything renders smoothly at 60fps. Our vision is to build a place where your team can collaborate on data analysis. You can write Python, AI Prompts, and Formulas in one spreadsheet feeding each other data and updating automatically. Quadratic is built…

I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Hi HN! We just shipped the public beta of the hosted version of Mathesar, our open source “intuitive spreadsheet UI, full PostgreSQL power” project. Until now, using Mathesar meant installing and running it yourself. Now you can use Mathesar for free without having to maintain your own infrastructure at https://mathesar.cloud. Mathesar Cloud is run by the Mathesar maintainers through the 501(c)(3) nonprofit that already maintains the open source project. We’re committed to ALWAYS keeping Mathesar 100% open source (no open core), nonprofit, and treat self-hosting as a first-class…
