Show HN: Cj–tiny no-deps JIT in C for x86-64 and ARM64 Hey y’all! About 7 years ago, I had this idea to write a JIT with an autogenerated backend for x86 based on the ISA specs. I sketched something out and then just kinda let it sit. I picked it up again a few weeks ago and made a complete-ish backend for both x86 and ARM64. It has no dependencies, the backends are completely autogenerated (by horrible, horrible JS scripts), and I built a small abstraciton layer for things like functions prologues etc. It’s super duper early and will probably break on your machine, but it’s good enough to compile some cool examples (look at the examples directory: https://ift.tt/VKQA8XE... , my personal favorite is the minimal language implementation: https://ift.tt/bEgMJq0... ). It doesn’t have anything except basically a fancy JIT assembler with some helpers as of yet. No register allocator, a lot of ABI details will still have to be figured out manually (though of course feel free to add anything t...

Show HN: Dev Cockpit (OSS) – TUI System Monitor for Apple Silicon Built a terminal dashboard for my M2 Mac because I wanted something better than jumping between Activity Monitor, terminal commands, and random cleanup scripts. What it does: Real-time charts for CPU, memory, disk... Quick actions menu - one key to flush DNS, fix WiFi, kill processes... Clean up all the dev cache garbage in one place (npm, Homebrew, Xcode, Go, Yarn) System insights with performance scoring Basically everything I was doing manually or with different tools, now in one TUI. Written in Go, GPL-3.0. https://ift.tt/D7wNdxM Install: curl -fsSL https://ift.tt/QVDzvwj... | bash Would appreciate feedback on the UI and what other quick actions or monitoring would be useful. https://devcockpit.app November 5, 2025 at 10:56PM

Show HN: Strange Attractors – Visualized with Easylang This post about strange attractors isn't as cool as this recent one: https://ift.tt/rLoMndR . My visualization runs with my programming language, which is interpreted by WASM code and uses JS and Canvas – without WebGL. https://ift.tt/ZVE6BKx November 5, 2025 at 09:25PM

Show HN: Nallely – a modular reactive Python system for custom MIDI instruments Hi HN! I'm Vince. I built Nallely, a modular reactive Python framework for creating custom MIDI instruments by patching signal-processing modules together, like a modular synthesizer for controls systems. Nallely focuses on real-time, thread-isolated, reactive behavior, letting you experiment with emergent behaviors. Demo video: https://www.youtube.com/watch?v=rbMnKAdqAVI building a patch from scratch and hot-debugging a running instance near the end. Key features: * Visual patching interface for connecting reactive modules (neurons), * Extensible via Python API, WebSocket, and/or code generation, * Integrates any input source (MIDI, webcam, ...) to control synthesizers. # Yes, but why? Existing software/libraries that proposes MIDI manipulation are powerful but not friendly to live experimentation. They are low-level, hard to rewire on the fly, and often heavy for embedded or headless setups. I wanted ...
