A data format similar to JSON, but richer and more extensible. Think of it as "JSON with superpowers."

HipKittens is an opinionated collection of programming primitives to help developers realize the hardware's capabilities. Includes optimized register tiles, 8-wave and 4-wave kernel patterns instead of wave-specialization to schedule work within processors. Also includes chiplet-optimized cache reuse patterns to schedule work across processors.

Nice writeup from Atlassian, makers of Jira and Confluence. Includes details about tuning specific JVM parameters, looking for CPU L3 cache misses, and measuring TLB tablewalks.

A modern alternative to htop, with a gamified interface.

This article reviews static stretching’s impact on muscle‑tendon mechanics, strength, and performance. Findings suggest moderate durations can improve range of motion, though excessive pre‑activity stretching may transiently reduce force production, influencing warm‑up strategies.

This review highlights eccentric overload’s ability to produce high force with lower metabolic cost, improve tendon stiffness, and enhance functional performance. Practical applications include slow‑negative push‑ups, tempo squats, and lowered‑resistance moves for injury‑prevention programs.

This meta‑analysis reviews SMR tools (foam rollers, balls) for ROM, soreness, and performance. Findings support modest gains in flexibility and recovery, recommending brief, targeted applications before training or during cool‑down.

The ACSM review outlines linear, daily undulating, and block periodization models, detailing volume, intensity, frequency, and recovery. It informs systematic progression for hypertrophy, strength, and power, enabling trainers to design safe, effective programs.

This review details the original Tabata protocol (20 seconds all‑out, 10 seconds rest × 8), its research on VO2max and anaerobic capacity, and programming considerations for trained and novice populations. It emphasizes intensity management and fatigue monitoring.
