Show HN: SCPN Fusion Core – Tokamak plasma SIM and neuromorphic SNN control https://ift.tt/RPcjOao

Show HN: SCPN Fusion Core – Tokamak plasma SIM and neuromorphic SNN control SCPN Fusion Core is an open-source Python/Rust suite for tokamak plasma simulation with neuro-symbolic compilation to stochastic spiking neural networks for real-time, fault-tolerant control. Key features: - 26 simulation modes (equilibrium, transport, optimizer, flight simulator, neuro-control, etc.) - Neuro-symbolic compiler: Petri nets → stochastic LIF neurons (sub-ms latency, 40%+ bit-flip resilience) - Validation: SPARC high-field equilibria + ITPA H-mode database (20 entries, 10 machines) + IPB98(y,2) scaling - Multigrid solvers, property-based testing, Rust acceleration, Streamlit dashboard - Install: pip install scpn-fusion GitHub: https://ift.tt/8WA5wrU Built to explore neuromorphic approaches to fusion reactor control. Happy to answer questions about the models, compiler, validation, or performance. https://ift.tt/8WA5wrU February 12, 2026 at 01:09AM

Show HN: Rawkit – Free, no-ads developer tools that run in the browser https://ift.tt/Z1N8b5p

Show HN: Rawkit – Free, no-ads developer tools that run in the browser Hey HN, I built rawkit.dev, a collection of browser-based developer utilities. No ads, no signups, no tracking. Everything processes client-side — your data never touches a server. The tools: - JSONForge: JSON editor with tree/graph views, diff, transform, JQ-style queries, format conversion - SQLSandbox: SQLite via WASM — import CSVs, write SQL, join across files - Regexplorer: Regex builder with live matching, plain English mode,nmulti-language export - SiftLog: Log file viewer with auto-detection, severity filtering, regex search, timeline - Tabulate: CSV/TSV viewer with spreadsheet-style filtering and sorting Tech: Vanilla HTML/CSS/JS. No frameworks, no build step. Each tool is essentially 3 files(index.html, css and .js file) I built these because I was sick of ad-ridden, upload-your-data-to-our-server alternatives for tasks I do daily. The goal is to keep adding tools that developers actually need. Curious what tools you'd want to see next https://rawkit.dev/ February 11, 2026 at 11:26PM

Show HN: Itsyhome – Control HomeKit from your Mac menu bar (open source) https://ift.tt/65cj48g

Show HN: Itsyhome – Control HomeKit from your Mac menu bar (open source) Hey HN! Nick here – developer of Itsyhome, a menu bar app for macOS that gives you control over your whole HomeKit fleet (and very soon Home Assistant). I run 130+ HomeKit devices at home and the Home app was too heavy for quick adjustments. Full HomeKit support, favourites, hidden items, device groups, pinning of rooms/accessories/groups as separate menu bar items, iCloud sync – all in a native experience and tiny package. Open source ( https://ift.tt/FJLng4z ) and free to use (there is an optional one-time purchase for a Pro version which includes cameras and automation features). Itsyhome is a Mac Catalyst app because HomeKit requires the iOS SDK, so it runs a headless Catalyst process for HomeKit (and now Home Assistant) access while using a native AppKit plugin over a bridge protocol to provide the actual menu bar UI – since AppKit gives you the real macOS menu bar experience that Catalyst alone can't. It comes with deeplink support, a webhook server, a CLI tool (golang, all open source), a Stream Deck plugin (open source, all accessories supported), and the recent update also includes an SSE event stream (HomeKit and HA) - you can curl -N localhost:8423/events and get a real-time JSON stream of every device state change in your home. Home Assistant version is still in beta – would anyone be willing to test it via TestFlight? Appreciate any feedback and happy to answer any questions. https://itsyhome.app February 10, 2026 at 12:31PM

Show HN: Printable Classics – Free printable classic books for hobby bookbinders https://ift.tt/Awmgvut

Show HN: Printable Classics – Free printable classic books for hobby bookbinders I created a site ( https://ift.tt/uTcW9eY ) that allows you to download classic books and customize things like the font size, page size, and the cover. As part of this, I wrote a software pipeline that takes epubs, html files, or pdfs and converts them into formatted books with custom covers, page numbers, chapter formatting, etc. I used an LLM for categorizing the books. There's a nice way to filter such that you could easily find "Young Adult, Ancient, Fantasy" for example. When downloading from the site, the PDFS are rendered in a work queue. Hopefully the server I'm using won't get overwhelmed. It takes around 10-15 seconds to generate for most books. Most of the books currently on the site are from Standard Ebooks. I plan to add more books from Archive.org and Project Gutenberg over time. I also created a little guide on how you can print and bind books at home with around $200 in equipment. ( https://ift.tt/xXkjzyW ) Printable versions of the Harvard Classics are available here: https://ift.tt/ye62DzC This is an example of direct PDF conversion. Hopefully this is useful to some people. I plan to use the books here for home education myself so it will at least be useful to me. I'd like to add a guide with top suggestions by age level and some educational theory on how I made the selections. I'm happy to take any feedback on the site or answer any questions. There is also the option to have the books professionally printed through a print on demand provider. I'm hoping that could be a way to pay for the site hosting. Thanks for checking it out! https://ift.tt/uTcW9eY February 9, 2026 at 02:09AM
