Haserl is a small cgi wrapper that allows "PHP" style cgi programming, but uses a UNIX bash-like shell or lua as the programming language. It is very small, so it can be used in embedded environments, or where something like PHP is too big.

It combines three features into a small cgi engine: * It parses POST and GET requests, placing form-elements as name=value pairs into the environment for the CGI script to use. This is somewhat like the uncgi wrapper.
* It opens a shell, and translates all text into printable statements. All text within <? ... ?> constructs are passed verbatim to the shell. This is somewhat like writing PHP scripts.
* It can optionally be installed to drop its permissions to the owner of the script, giving it some of the security features of suexec or cgiwrapper.
Hexter is a software synthesizer that models the sound generation of a Yamaha DX7 synthesizer. It can easily load most DX7 patch bank files, edit those patches via a built-in editor or MIDI sys-ex messages (ALSA systems only), and recreate the sound of the DX7 with greater accuracy than any previous open-source emulation (that the author is aware of....)

Hexter operates as a plugin for the DSSI Soft Synth Interface. DSSI is a plugin API for software instruments (soft synths) with user interfaces, permitting them to be hosted in-process by audio applications.
The Portable Hardware Locality (hwloc) software package provides an abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, shared caches, processor sockets, processor cores and processing units (logical processors or "threads"). It also gathers various system attributes such as cache and memory information. It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently.

hwloc may display the topology in multiple convenient formats. It also offers a powerful programming interface (C API) to gather information about the hardware, bind processes, and much more.
