Giovanni Tomaselli and collaborators explore the potential presence of “gravitational atoms” surrounding black holes, formed by clouds of axions or other light bosons. These gravitational atoms could impact the evolution of black hole binaries, affecting their orbital motion through complex interactions. The researchers have identified various evolutionary paths these binaries could take, considering factors such […]
This post covers hardware diagnostics, firmware reverse engineering, and coincidental similar datasheets from Taiwanese chip manufacturers. The author ventures into fixing a broken Elgato Game Capture HD60 S USB 3.0 device by identifying and replacing faulty chips. Despite successfully replacing the regulators, issues persist with the LED lights. After a thorough investigation, the culprit turns […]
Johann Carl Friedrich Gauss, a renowned mathematician, set his sights on achieving a mathematical feat: a regular heptadecagon. This 17-sided shape, symbolizing one of Gauss’s greatest contributions to math, was used to solve a longstanding problem in math when Gauss was just 18 years old. Despite the challenge, Gauss demonstrated that this complex shape was […]

The Importance of Stupidity in Scientific Research is an eye-opening essay that challenges the traditional idea of intelligence. Martin Schwartz argues that feeling stupid is essential for truly understanding complex concepts, especially in mathematics. The article highlights the unique nature of math, where new ideas can seem impossible until they suddenly click. The process of […]
Developing games for PC involves dealing with user input from mouse, keyboard, and gamepads, especially on Windows. Popular games often have mouse input issues with high-end mice due to legacy input cluttering message queues. Using the Raw Input API is key for unaltered input. Input handling can be complex, especially with high polling rate mice. […]
