Dr. Manisha Caleb from the University of Sydney Institute for Astronomy has published on a peculiar neutron star that is rotating exceptionally slowly, a rarity amongst the more than 3000 discovered neutron stars to date. This discovery challenges current understandings of radio neutron star behavior and provides new perspectives on stellar life cycles. Utilizing the […]
This post discusses the creation of a custom 3dfx-powered video card for laptops with MXM slots. The author details the challenges faced in making the card compatible with different systems and how they overcame them. They share images of the board and its size compared to a standard Voodoo 4. The author also demonstrates the […]
The LaTeX Project showcases a collection of Well Tagged PDF documents conforming to PDF/UA-2, including examples of math equations, arXiv papers, course notes, and conference papers. The files were generated using LuaLaTeX. While there are limited validators for UA-2 compliance, viewers that modify PDFs may break the standard. Examples include MathML-associated files for tagging mathematics, […]
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 […]
