ActiveSupport is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. It includes support for multibyte strings, internationalization, time zones, and testing.

Bootsnap is a library that plugs into Ruby, with optional support for YAML, to optimize and cache expensive computations.

Ruby on Rails is a full-stack web framework optimized for programmer happiness and sustainable productivity. It encourages beautiful code by favoring convention over configuration.

Action Cable integrates WebSockets with Rails applications. Through WebSockets it allows for real-time features in web applications.

Tool to help debug / hack at the BCM283x GPIO. You can dump the state of a GPIO (or all GPIOs). You can change a GPIO mode and pulls (and level, if set as an output). Beware that this tool writes directly to the BCM283x GPIO registers, ignoring anything else that may be using them (like Linux drivers).

rpi-imager is graphical utility to easily provision and flash a memory card with an operating system image suitable for the Raspberry Pi single board computer.

This package contains device tree overlay binaries to support the WaveShare SpotPear TFT LCDs on the Raspberry Pi.

This package package contains libraries to interface to EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, VFC and OpenVG. It also provides the dtmerge, dtoverlay, dtparam, raspivid and tvservice commands, among others.

This package provides a C library for Broadcom BCM 2835 as used in the Raspberry Pi

This package provides a bootloader for the ARM part of a Raspberry Pi. Note: It does not work on Raspberry Pi 1.

The fbcp command provided by this package can be used to copy the primary frame buffer to the secondary frame buffer of a Raspberry Pi. It can for example mirror the primary HDMI output to a secondary LCD display connected to the Raspberry Pi board.

Ratpoison is a simple window manager with no fat library dependencies, no fancy graphics, no window decorations, and no rodent dependence. It is largely modelled after GNU Screen which has done wonders in the virtual terminal market.

The screen can be split into non-overlapping frames. All windows are kept maximized inside their frames to take full advantage of your precious screen real estate.

All interaction with the window manager is done through keystrokes. Ratpoison has a prefix map to minimize the key clobbering that cripples Emacs and other quality pieces of software.

The rcm suite of tools is for managing dotfiles directories. This is a directory containing all the .*rc files in your home directory (.zshrc, .vimrc, and so on). These files have gone by many names in history, such as “rc files” because they typically end in rc or “dotfiles” because they begin with a period. This suite is useful for committing your rc files to a central repository to share, but it also scales to a more complex situation such as multiple source directories shared between computers with some host-specific or task-specific files.

FreeRDP implements Microsoft's Remote Desktop Protocol. It consists of the xfreerdp client, libraries for client and server functionality, and Windows Portable Runtime (WinPR), a portable implementation of parts of the Windows API.

Xrdp provides a graphical login to remote machines using Microsoft Remote Desktop Protocol (RDP). Xrdp accepts connections from a variety of RDP clients:

• FreeRDP

• rdesktop

• KRDC

• NeutrinoRDP

• Windows MSTSC (Microsoft Terminal Services Client, aka mstsc.exe)

• Microsoft Remote Desktop (found on Microsoft Store, which is distinct from MSTSC).

xorgxrdp is a collection of modules to be used with a pre-existing X.Org install to make the X server act like X11rdp. Unlike X11rdp, you don't have to recompile the whole X Window System. Instead, additional modules are installed to a location where the existing Xorg installation would pick them.

rdesktop is a client for Microsoft's Windows Remote Desktop Services, capable of natively speaking Remote Desktop Protocol (RDP). It allows users to remotely control a user's Windows desktop.

Lucene++ is an up to date C++ port of the popular Java Lucene library, a high-performance, full-featured text search engine.

LRDF is a library to make it easy to manipulate RDF files describing LADSPA plugins. It can also be used for general RDF manipulation. It can read RDF/XLM and N3 files and export N3 files, and it also has a light taxonomic inference capability.

Serd is a lightweight C library for RDF syntax which supports reading and writing Turtle and NTriples. Serd is not intended to be a swiss-army knife of RDF syntax, but rather is suited to resource limited or performance critical applications (e.g. converting many gigabytes of NTriples to Turtle), or situations where a simple reader/writer with minimal dependencies is ideal (e.g. in LV2 implementations or embedded applications).

Header Dictionary Triples (HDT) is a compression format for RDF data that can also be queried for Triple Patterns. This package provides a C++ library as well as various command-line tools to to work with HDT.

RDFLib is a Python library for working with RDF, a simple yet powerful language for representing information.
