I started this archive because folders on my laptop were turning into a tangled second brain. I work on sparse small language models[*], write cascaded feedback algorithms[*], slap funk grooves on a 4-string bass, and study Traditional Chinese characters in Tamsui.
Grouped-Subspace Latent Attention & eliminating KV-cache memory saturation on 15W NPU silicon.
Intel Core Ultra + RTX 40/50 Series / ESP32 BLE Mesh Nodes / Custom Slap Bass Rig.
Everyone is renting clusters of H100s to train 70B parameter models that regurgitate encyclopedias. I am obsessed with getting a 350M parameter model to reason sharply inside a 15W laptop NPU.
Slapping a bass guitar isn't musical showmanship; it is an exercise in tactile kinetic impulse. You strike the metal fret with the bone of your thumb, recoil instantly, and leave silence for the snare.
Most hobbyist robotics tutorials tell you to tweak three constants: Kp, Ki, and Kd. Then your motor shakes violently against the table. Here is what happened when I published dual-loop-controller to PyPI.
You want to understand distributed consensus, UDP protocol translation, and tick drift under heavy load? Stop reading textbook chapters on Paxos and run a hybrid Java/Bedrock Minecraft server for two hundred unpredictable kids.
Packing your life into two suitcases changes how you perceive permanence. In Tangerang, life was humid, fast-paced, and filled with school projects. In Tamsui, the wind comes off the river and the characters on the storefronts carry three thousand years of brush strokes.
Cascaded dual-loop PID and velocity-position state feedback engine for high-precision edge actuation.
Offline emergency beacon and peer-to-peer safety mesh protocol powered by Bluetooth Low Energy (BLE).
Real-time game board state recognition and automated solver pipeline using OpenCV and Android Debug Bridge.
High-throughput Paper/Spigot server architecture enabling zero-desync cross-play between Java and Bedrock clients.
Experimental sparse mixture-of-experts attention kernels targeting low-power edge NPUs.
People spend weeks tuning the integral gain (Ki) when their physical mechanism simply has Coulomb friction. If your actuator is physically sticking at low PWM, math won't unstick it — you need a deadband dither or an inner velocity loop that kicks in before the position error integrates into a violent jump.
Slap bass is 80% thumb pivot geometry and 20% amplification. If you slap through the string like you're playing an electric guitar with a pick, you kill the bounce. Your thumb must rebound off the steel before the string even reaches its maximum excursion. The groove lives in the acoustic rebound.
In 3x3 speedsolving, turning faster than 9 TPS (turns per second) with blind hesitation is worse than turning at 5 TPS with unbroken lookahead. While inserting the front-right F2L pair, your eyes must be scanning the opposite back-left corner for the next edge orientation. Software pipelines are the exact same: pipeline stalls kill throughput.
