The content discusses the disparity in responsiveness between fast-moving technological entities like TikTok and slower-moving institutions such as educational systems and democratic governments. It highlights a framework proposed by entrepreneur Naval Ravikant that identifies three types of leverage—labor, capital, and code—each operating at different speeds (linear, exponential, and systematic). The text describes a phenomenon called "leverage arbitrage," where those with higher-order leverage (e.g., tech companies) can extract value from systems more rapidly than those with

The post reflects a personal journey of learning electronics to create artificial fireflies, inspired by the absence of real ones. The author shares their initial ignorance about electronics, including confusion over basic concepts like voltage and current, and their eventual understanding through research and AI assistance. After assembling a basic blinking LED circuit, which surprisingly worked on the first try, the author encountered issues with the blink frequency and duration, realizing they needed it to blink only at night and at a slower pace. They discovered the use of a

The text critiques the reliance on over-hyped technological solutions, such as cryptocurrencies and certain fintech models, to address deep-rooted societal issues, particularly regarding financial wellbeing. It emphasizes that while some technology appears promising, it often fails to solve the underlying problems or lacks a clear purpose. There is a concern that many in the tech industry are chasing the next big innovation without true applications in mind. Moreover, the private sector is unlikely to resolve structural economic issues like precarity and may instead exploit these conditions for

The article discusses the "Sign in with Google" banners that appear on websites like Yelp, which are part of Google's One Tap user experience. It mentions that the StopTheMadness Pro browser extension can hide these banners, but they do not appear in Google Chrome at all. The author explains how to make Safari mimic Chrome by spoofing the User-Agent header, which removes the banners. However, Chrome does have its own popup annoyance—a One Tap dialog that appears if a user is already signed into their

Maister's Graphics Adventures explores low-level graphics and engine programming, focusing on topics of interest, particularly low-latency video streaming. The article discusses the significant challenges of streaming gameplay over a network, emphasizing the critical need for minimal latency—ideally around 20 milliseconds. To achieve this, GPU-accelerated video compression using codecs like H.264 and HEVC is employed, although strategies that increase latency, such as flexible rate control and B-frames, must be minimized. The author reflects

In a post written on July 26, 2025, the author reflects on the programming interface of threads compared to async/await in Python, revisiting a previous discussion prompted by Mark Shannon about virtual threads. The author acknowledges that async/await has effectively introduced concurrent programming to a broader audience, despite its complexity and the need for intricate internal mechanisms. In contrast, threads are simpler but have historically presented issues due to suboptimal APIs. The author notes that while async/await prevents suspension until an

Kumi is a computational rules engine for Ruby designed to handle complex, interdependent calculations with static validation and dependency tracking. It allows users to calculate U.S. federal taxes using concise and validated code while ensuring consistency across business rules. Kumi schemas are built from four core primitives: Inputs (data with validation), Values (computed attributes), Traits (boolean conditions for branching), and Functions (computational blocks). The engine performs static analysis during schema definition to catch logical errors before runtime, producing an internally consistent
