| [eudev](https://wiki.gentoo.org/wiki/Project:Eudev) | eudev is a fork of systemd-udev with the goal of obtaining better compatibility with existing software such as OpenRC and Upstart, older kernels, various toolchains and anything else required by users and various distributions. |
| [hwloc](http://www.open-mpi.org/projects/hwloc/) | The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information as well as the locality of I/O devices such as network interfaces, InfiniBand HCAs or GPUs. It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently. |
| [LibreSSL](http://www.libressl.org/) | LibreSSL is a version of the TLS/crypto stack forked from OpenSSL in 2014, with goals of modernizing the codebase, improving security, and applying best practice development processes. Primary development occurs inside the OpenBSD source tree with the usual care the project is known for. On a regular basis the code is re-packaged for portable use by other operating systems (Linux, FreeBSD, Windows, etc). |
| [OpenSSL](http://www.openssl.org/) | The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolchain implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. |
