Releasing the first 2-bit ternarized Qwen3.8: TernaryQuench-27B huggingface.co/penkia/Ternar… Also the complete open-source recipe: calibration trace generation, a CAT-Q/AYOT-inspired trainer, and GGUF/MLX exporters github.com/penk/ternary-quen…

Reverse engineering the CAT-Q trainer worked surprisingly well, The reconstruction gets PPL 38.7528 vs 34.51 reported in the paper, close enough that I’m fairly confident the direction is right 👉 artifact: huggingface.co/penkia/catq-q…

To be honest, never thought I'd end up releasing models on HF. 😆 I just wanted to implement the stack : ternarization -> calibration -> MLX conversion -> coding-agent adapter

I (well, Claude) made the 2-wall vase mode for Cura. One continuous spiral prints the outer wall, no z-seam, and 2x stronger! 😆 macOS26 build: drive.google.com/file/d/1_Gg… (192MB) patch for CuraEngine: gist.github.com/penk/0b0b01f…

I built QmlAgent to provide coding agents structured runtime evidence instead of screenshots: walk the live UI tree, fire real input events, catch binding/layout failures, map them back to the QML source, and verify the fix. Inspect -> diagnose -> repair a running Qt Quick app, no more human-in-the-loop Ask your coding agent to give it a try :-) ⭐ github.com/penk/qmlagent

Omarchy Quattro's code base is 4x the size of the 3-series. Thanks largely to 40K lines of Quickshell QML! But the OVERALL system is just a quarter of the code it was before, because we've dropped a bajillion dependencies. And ISO is 20% smaller, installs up to 40% faster!

Resin printed keycaps usually look cheap, but surprisingly, they work pretty well as LED diffusers! 😆 #自作キーボード

Last build of the year: I designed the EDC36 as an integral part for my next cyberdeck build and figured I’d share the files in case anyone else finds them useful. Repo: github.com/penk/EDC36 #自作キーボード

I used Frank Adams' awesome T4p1_thruhole PCB and a 22-pin 1.25mm pitch FFC connector. Too impatient to wait for the Teensy 4.1 order to arrive, I used that board as a breakout, slapped on an RP2040 Zero, and translated the Arduino code to QMK firmware. Test video:

I selected “Surface Finishing: No” for the resin print, and the package came with a piece of 240 grid sandpaper. That’s the most passive-aggressive act I’ve seen from JLC. 😂 #自作キーボード #WeirdFlexButOk
