Cosmic Physics Calculator v1.0 is an advanced, terminal-based computational suite designed for astrophysicists, cosmologists, and physics students. - blackmatriXblack/Cosmic-Physics-Calculator-
Cosmic Physics Calculator v1.0 is an advanced, terminal-based computational suite designed for astrophysicists, cosmologists, and physics students. Developed in standard C, this application provides a unified interface for solving complex problems across classical mechanics, thermodynamics, quantum mechanics, special/general relativity, and cosmology. Unlike basic calculators, this tool integrates a comprehensive database of physical constants (e.g., Planck constant, Hubble constant, Solar mass) and implements sophisticated algorithms for multi-variable calculations, such as the Ideal Gas Law validation and Multi-Planetary Gravity simulations. It serves as both a practical calculation…from github.com

I built this because measuring my age in years felt boring—I wanted to see the kilometers. The first version only used Earth's orbital speed (~30km/s), but the number moved too slowly. To get the "existential dread" feeling, I switched to using the Milky Way's velocity relative to the CMB (~600km/s). The math takes some liberties (using scalar sum instead of vector) to make the speed feel "fast," but it gets the point across. Under the hood, it's a single HTML file with zero dependencies. No React, no build step. The main challenge was the canvas starfield—I had to pre-allocate the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
