oh - A surprisingly powerful Unix shell

•    Go

Oh is a Unix shell. If you've used other Unix shells, oh should feel familiar. Where oh diverges from traditional Unix shells is in its programming language features.

concurrently - Run commands concurrently. Like `npm run watch-js & npm run watch-less` but better.

•    Javascript

Run multiple commands concurrently. Like npm run watch-js & npm run watch-less but better. I like task automation with npm but the usual way to run multiple commands concurrently is npm run watch-js & npm run watch-css. That's fine but it's hard to keep on track of different outputs. Also if one process fails, others still keep running and you won't even notice the difference.

sled - sled likes eating data: alpha modern embedded database

•    Rust

An alpha modern embedded database. We also support merge operators.

Vibur Object Pool - Concurrent Java Object Pool

•    Java

Vibur Object Pool is a general-purpose concurrent Java object pool which provides both validating and non-validating pool implementations. The pool is built entirely using standard Java concurrency utilities, does not use any synchronized blocks/methods, and does not have any external dependencies. The pool is an excellent choice for pooling/caching of expensive to create Java objects such as database (or any other) socket connections and similar.

Node.JS - Builds Scalable Network Programs

•    Javascript

Node.js is a server-side JavaScript environment that uses an asynchronous event-driven model. It could handle thousands of concurrent connections. This allows Node.js to get excellent performance based on the architectures of many Internet applications. It is an evented I/O for V8, which is Google's open source JavaScript engine.

high-scale-lib

•    Java

A collection of Concurrent and Highly Scalable Utilities. These are intended as direct replacements for the java.util.* or java.util.concurrent.* collections but with better performance when many CPUs are using the collection concurrently.

ElixirBooks - List of Elixir books

Official Elixir starting guide that will take you through the language foundations. You will also explore how to build projects with Mix and OTP, and it will introduce you to more advanvced techniques suchs as meta-programming. Adoption is more than programming. Elixir is an exciting new language, but to successfully get your application from start to finish, you’re going to need to know more than just the language. You need the case studies and strategies in this book. Learn the best practices for the whole life of your application, from design and team-building, to managing stakeholders, to deployment and monitoring. Go beyond the syntax and the tools to learn the techniques you need to develop your Elixir application from concept to production.

Zio - A type-safe, composable library for async and concurrent programming in Scala

•    Scala

ZIO is a zero-dependency Scala library for asynchronous and concurrent programming. It is powered by highly-scalable, non-blocking fibers that never waste or leak resources, ZIO lets you build scalable, resilient, and reactive applications that meet the needs of your business.

cloe - Cloe programming language

•    Go

Cloe is the timeless functional programming language. It aims to be simple and practical. Go 1.8+ is required.

Win32 Registry Activity Monitor

•    DotNet

A simple program written in Delphi that monitors registry activity on win32 systems. In short a registry key and class are statically added to the code, the program is then run and as changes are made by other applications to the key and all its sub keys the changes are logged an

A Concurrent Hashtable

•    DotNet

A hashtable implementation that allows simultaneous reads and writes from multiple threads. Also offering a concurrent Dictionary and WeakDictionary as hashtable specializations.

BadKid Core Library

•    CSharp

C# Utilities ranging over Maths, Collections, Artificial Intellegence, Data, IO, Reflection, Validation, Dictionary, Random Generators. Many commonly found utilities but managed into a coherant form.

Practical Parallel and Concurrent Programming

Eight two-week units of courseware (slides, lecture notes, samples, tools) for teaching how to program parallel/concurrent applications at a high-level using Microsoft’s Parallel Extensions to the .NET Framework.

WParse

•    DotNet

WParse is a CLS compliant class library developed in C# with .NET 4.0 as the target framework. WParse makes it easier to parse log files for the game Wurm Online and generate interesting and useful statistics from the logged data. It includes scripting support for parsers in C#.

Concurrent Extensions Library (CEL)

•    DotNet

Concurrent Extensions Library (CEL) provides functionality and implementations commonly useful in concurrent programming.

queue - Asynchronous function queue with adjustable concurrency

•    Javascript

Asynchronous function queue with adjustable concurrency. This module exports a class Queue that implements most of the Array API. Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods. Processing begins when you call q.start().

pipeline - Pipeline is a package to build multi-staged concurrent workflows with a centralized logging output

•    Go

A package to build multi-staged concurrent workflows with a centralized logging output. The package could be used to define and execute CI/CD tasks(either sequential or concurrent). A tool with similar goals would be Jenkins Pipeline. However, compared to Jenkins Pipeline, this package has fewer constructs since the logic is specified in code, as opposed to a Jenkinsfile.
