    Pure Bash Bible

    Pure Bash Bible

    A collection of pure bash alternatives to external processes

    pure-bash-bible is a collection of pure Bash scripting techniques that demonstrate how to accomplish common and complex tasks using only built-in Bash features. Its goal is to reduce reliance on external tools like sed, awk, or grep, which can slow down scripts and add unnecessary dependencies. The project is organized as a reference book of function-based code snippets, each showcasing practical solutions for string manipulation, text processing, file operations, and more. By relying exclusively on Bash built-ins, these methods can make scripts faster, more portable, and easier to maintain. Every snippet is linted with shellcheck, and many have accompanying tests, ensuring correctness and usability. The project is not only a coding resource but also an educational tool for Bash users who want to better understand the full power of the language.

    NSync

    NSync

    nsync is a C library that exports various synchronization primitives

    nsync is a portable C library that provides a collection of advanced synchronization primitives designed to facilitate safe and efficient multithreaded programming. It offers reader-writer locks, condition variables, run-once initialization, waitable counters, and waitable bits for coordination and cancellation between threads. Unlike traditional pthreads-based synchronization, nsync introduces conditional critical sections, allowing developers to wait for arbitrary conditions without explicit signaling or complex loop-based logic. This approach simplifies concurrency management and often improves readability and maintainability of multithreaded code. The library emphasizes efficiency, with locks and condition variables occupying minimal memory and supporting cancellation mechanisms through nsync_note objects rather than thread-level cancellation. Designed with portability and performance in mind, nsync can be compiled on Unix-like systems and Windows using a C90 compiler.

    Hacker Laws

    Hacker Laws

    Laws, theories, principles and patterns useful to developers

    Laws, Theories, Principles and Patterns that developers will find useful. There are lots of laws which people discuss when talking about development. This repository is a reference and overview of some of the most common ones. Principles and laws to follow such as: If a program is made up of two parts, part A, which must be executed by a single processor, and part B, which can be parallelised, then we see that adding multiple processors to the system executing the program can only have a limited benefit. It can potentially greatly improve the speed of part B - but the speed of part A will remain unchanged. Also, theories like The Broken Windows Theory, which suggests that visible signs of crime (or lack of care of an environment) lead to further and more serious crimes (or further deterioration of the environment). Conway's Law suggests that the technical boundaries of a system will reflect the structure of the organisation. These among others, are featured in this project.

    Bash Infinity is a standard library and a boilerplate framework for writing tools using bash. It's modular and lightweight while managing to implement some concepts from C#, Java or JavaScript into bash. The Infinity Framework is also plug & play: include it at the beginning of your existing script to import any of the individual features such as error handling, and start using other features gradually. The aim of Bash Infinity is to maximize the readability of bash scripts, minimize the amount of code repeat and create a central repository for a well-written, and a well-tested standard library for bash. Bash Infinity transforms the often obfuscated "bash syntax" to a cleaner, more modern syntax. Some components are more sturdy than others, and as-it-stands the framework lacks good test coverage (we need your help!).
