NumPy is the fundamental package needed for scientific computing with Python. This package contains:
- a powerful N-dimensional array object
- sophisticated (broadcasting) functions
- tools for integrating C/C++ and Fortran code
- useful linear algebra, Fourier transform, and random number capabilities.
It derives from the old Numeric code base and can be used as a replacement for Numeric. It also adds the features introduced by numarray and can be used to replace numarray.
Torch is a scientific computing framework with wide support for machine learning algorithms that puts GPUs first. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation.
libuv is a multi-platform support library with a focus on asynchronous I/O. It was primarily developed for use by Node.js, but it's also used by Luvit, Julia, pyuv, and others.
Lwan is a high-performance & scalable web server for glibc/Linux platforms.
In development for almost 4 years, Lwan was until now a personal research effort that focused mostly on building a solid infrastructure for a lightweight and speedy web server:
- Low memory footprint (~500KiB for 10k idle connections)
- Minimal memory allocations & copies
- Minimal system calls
- Hand-crafted HTTP request parser
- Files are served using the most efficient way according to their size
- No copies between kernel and userland for files larger than 16KiB
- Smaller files are sent using vectored I/O of memory-mapped buffers
- Header overhead is considered before compressing small files
- Mostly wait-free multi-threaded design
- Diminute code base with roughly 7200 lines of C code
It is now transitioning into a fully working, capable HTTP server. It is not, however, as feature-packed as other popular web servers. But it is free software, so scratching your own itches and making Lwan hum the way you want it to is possible.
netdata is a system for distributed real-time performance and health monitoring. It provides unparalleled insights, in real-time, of everything happening on the system it runs (including applications such as web and database servers), using modern interactive web dashboards.
netdata is fast and efficient, designed to permanently run on all systems (physical & virtual servers, containers, IoT devices), without disrupting their core function.
Skynet is a lightweight online game framework, and it can be used in many other fields.
Nuklear - is a minimal state immediate mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default renderbackend or OS window and input handling but instead provides a very modular library approach by using simple input state for input and draw commands describing primitive shapes as output. So instead of providing a layered library that tries to abstract over a number of platform and render backends it only focuses on the actual UI.
Kore is an easy to use web application framework for writing scalable web APIs in C. Its main goals are security, scalability and allowing rapid development and deployment of such APIs.
