    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.

    SVoice (Speech Voice Separation)

    SVoice (Speech Voice Separation)

    We provide a PyTorch implementation of the paper Voice Separation

    SVoice is a PyTorch-based implementation of Facebook Research’s study on speaker voice separation as described in the paper “Voice Separation with an Unknown Number of Multiple Speakers.” This project presents a deep learning framework capable of separating mixed audio sequences where several people speak simultaneously, without prior knowledge of how many speakers are present. The model employs gated neural networks with recurrent processing blocks that disentangle voices over multiple computational steps, while maintaining speaker consistency across output channels. Separate models are trained for different speaker counts, and the largest-capacity model dynamically determines the actual number of speakers in a mixture. The repository includes all necessary scripts for training, dataset preparation, distributed training, evaluation, and audio separation.

    AWS CodeBuild curated Docker images

    AWS CodeBuild curated Docker images

    AWS CodeBuild repository for managed Docker images

    When you call AWS CodeBuild to run a build, you must provide information about the build environment. A build environment represents a combination of operating system, programming language runtime, and tools that CodeBuild uses to run a build. The master branch will sometimes have changes that are still in the process of being released in AWS CodeBuild. When you provide information to CodeBuild about the build environment, you specify the identifier of a Docker image in a supported repository type. These include the CodeBuild Docker image repository, publicly available images in Docker Hub, and Amazon Elastic Container Registry (Amazon ECR) repositories that your AWS account has permission to access. We recommend that you use Docker images stored in the CodeBuild Docker image repository, because they are optimized for use with the service.

    Bash Infinity

    Bash Infinity

    A modern standard library / framework / boilerplate for Bash

    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!).

    Bocker

    Bocker

    Docker implemented in around 100 lines of bash

    Bocker is a minimal, educational reimplementation of core container (Docker-like) functionality, done in about a hundred lines of Bash script. Its purpose is not to replace Docker’s full feature set, but to illustrate container primitives—namespaces, cgroups, layering, filesystem manipulation, network namespaces, etc.—in a transparent, minimal form. With bocker you can perform basic operations such as pulling an image, running a container, exec into a container, listing containers, and removing them. Because it's written in shell, it is easy to read, reason about, and adapt for experiments or instructional use. It is not intended for production use due to performance, security, and missing features, but it is a useful tool for learning how containers work under the hood. Many learners and educators reference it when teaching container internals or when debugging container behavior in a minimal environment.

    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.
