In Praise of the 100-Page Idea: A Case for Brevity in Nonfiction

2024-12-22

Tracy Durnell argues for the value of concise nonfiction books, specifically those around 100 pages long. She finds these shorter works ideal for exploring a single, impactful idea without excessive detail, fitting modern readers' shorter attention spans. Durnell highlights several examples of excellent books in this length, contrasting them with longer works that she believes often dilute their core ideas through padding. She champions the efficiency of a focused approach, emphasizing the benefits of connecting multiple concise ideas to build a broader understanding over consuming lengthy, highly-detailed tomes.

Phugoid Oscillation: A Pilot's Nightmare

2024-12-27

A phugoid is an aircraft motion characterized by a repetitive cycle of climbing and descending, accompanied by changes in airspeed. Caused by variations in pitch and a nearly constant angle of attack, it can be triggered by factors like elevator input or control surface malfunctions. While sometimes a manageable nuisance, uncontrolled phugoids have been implicated in numerous aviation accidents, including the devastating Japan Airlines Flight 123 crash. Understanding phugoid dynamics is crucial for flight safety.

Entropy: A Rethink of Disorder in the Universe

2024-12-14
Entropy: A Rethink of Disorder in the Universe

Two hundred years ago, French engineer Sadi Carnot introduced the concept of entropy to quantify the universe's irreversible slide into decay. However, modern physics views entropy not simply as 'disorder,' but as a reflection of an observer's limited knowledge of a system. This new perspective illuminates the deep connection between information and energy, driving technological advancements at the nanoscale. From Carnot's steam engine to modern information engines, the concept of entropy continues to evolve, helping us understand the universe's workings and prompting us to rethink the purpose of science and our place within it.

Rust-Based Keyboard Firmware RMK: A Challenging Upgrade

The author flashed their Ferris Sweep keyboard with RMK, a Rust-based keyboard firmware, contrasting it with the previous QMK firmware. While RMK is younger and lacks QMK's extensive pre-built configurations, its Cargo-based package management and Rust features make configuration both appealing and challenging. The article details the author's journey from installing rmkit, configuring keyboard.toml (including the painful pin mapping process), creating vial.json, to finally flashing the firmware and debugging issues. Challenges included half-duplex UART communication and vial.json compatibility. Despite these hurdles, the author successfully runs RMK and shares their experience and suggested improvements. While less mature than QMK, RMK's asynchronous runtime and compile-time code generation make it a compelling project.

10x Programmer: How to Dramatically Increase Your Coding Speed

2025-02-20

This post argues for the importance of improving coding speed. The author compares the development time of two similar libraries, six and two years apart, demonstrating at least a 5x, and potentially 20-30x speed increase. This improvement stems from clearer goals, faster design decisions, and improved work processes. The author suggests a potential 10x speedup is achievable by improving mechanical skills like typing speed, reducing bugs, and refining workflows. This translates to more output, broader project choices, and more learning opportunities. The post explores the impact on project selection, feedback loops, tool development, and uses SQLite's optimization as an example of how small, incremental improvements compound to significant gains. The author concludes that increased speed is also more enjoyable.
