What it does

BioSequence Analyzer is a C-based command-line tool that performs comprehensive bioinformatics analyses—including molecular weight, melting temperature, translation, and isoelectric point calculations—on DNA, RNA, and protein sequences. - blackmatriXblack/biocalculator

BioSequence Analyzer is a command-line utility written in C designed to perform fundamental bioinformatics calculations on biological sequences. It supports three primary molecule types: DNA , RNA , and Proteins . The tool provides functionalities ranging from basic sequence statistics (length, GC content) to complex biophysical properties such as Melting Temperature ( $T_m$ using Nearest-Neighbor methods), Isoelectric Point (pI), and Molar Extinction Coefficients. This document outlines the installation, usage, supported calculations, and underlying algorithms implemented in main.c . The program requires a standard C compiler (e.g., gcc ) and links against the math library ( libm ). gcc -o…from github.com

    Hi 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.

  • Today, 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!
