TL;DR summary of stories on the internet
Duck Hunt on the Nintendo Entertainment System is a classic game, but the concept of hunting ducks goes back to a Looney Tunes short in 1951. Nintendo didn’t create video games connected to TVs until 1977, making you wonder what if you wanted to hunt ducks in 1976? Surprisingly, Sega had a similar game in […]

The author discusses the importance of clear and accurate technical explanations for laypeople, referencing Richard Feynman as inspiration. They criticize nonsensical error messages and advocate for more transparency in software communication, even if it means using technical terms. The focus is on providing users with a better understanding of the inner workings of machines without […]
Xv6 is a teaching operating system inspired by Unix V6 and Lions’ Commentary on UNIX. It was ported to RISC-V for a new undergraduate class at MIT. The source code and text for xv6 are available online. Developers are open to feedback on improving xv6 for educational purposes. Contact Russ Cox, Frans Kaashoek, and Robert […]
The author delves into the concept of Chebyshev approximation, emphasizing its importance in efficient mathematical computation on embedded systems. Amy and Bill’s cases illustrate the need for accurate results with minimal CPU power. Taylor series approximations are explored, revealing limitations in accuracy and range. The author then presents polynomial approximations as a more effective method, […]
PID 0 is the most misunderstood figure in the world of Unix PIDs, with misinformation and confusion rampant across the web. Despite common misbeliefs, PID 0 does exist, serving as the kernel’s caretaker with responsibilities in the realms of process scheduling and power management. The history of PID 0 in Unix dates back to earlier […]
ASCII Silhouettify is the go-to app for converting images into ASCII silhouettes, characterized by geometric shapes rather than lines or textures. It is limited to flat graphics with minimalistic forms lacking shading, making it ideal for logos and banners. The app focuses on traditional ASCII characters, offering output options like colored text, HTML, or Neofetch […]
Own a personal weather station and internet connection? The NWS and local TV meteorologists want your data for more accurate forecasts. Your data can help improve computer models and make meteorologists aware of local micro-climates. Ever wonder where small town weather data on TV comes from? Personal weather stations like yours! By joining the Citizen […]
The Sol Mate e-Paper Display project was born from the initial creation of the Sol Mate GPT. This repository contains all the code needed to display a weather report for any location on a Raspberry Pi with a Waveshare e-Paper display. The hardware required includes a Raspberry Pi 5 and a Waveshare e-Paper 7.3″ display. […]
The V8 team has developed the V8 Sandbox to tackle browser exploits originating from memory safety bugs. Despite V8 being written in C++, the vulnerabilities are complex logic issues rather than traditional memory corruption bugs. GraalJS, a JavaScript engine built using Truffle and Java, eliminates memory safety bugs by design. Truffle fundamentally changes VM architecture […]
Sea levels have risen globally by 21cm to 24cm since 1880, mainly due to water expanding as it warms and meltwater from Greenland and Antarctica. This threatens coastal properties, livelihoods, and low-lying countries, allowing destructive storms to reach farther inland. As melting polar ice contributes more, some suggest using technology like underwater curtains or ice-thickening […]
