marcel provides MIME type detection using magic numbers, filenames, and extensions

This gem can compare HTML and assert certain elements exists. This is useful when writing tests.

The ammeter gem makes it easy to write specs for Rails generators. An existing user is rspec-rails, which uses ammeter to spec its own generators.

Spring is a Ruby on Rails application preloader. It speeds up development by keeping your application running in the background so the application does need to boot it every time you run a test, rake task or migration.

This gem provides Ruby and Ruby on Rails integration with Autoprefixer, which can parse CSS and add vendor prefixes to CSS rules using values from the Can I Use website.

Turbo aims to be as fast as single-page web application without having to write any JavaScript. Turbo accelerates links and form submissions without requiring server-side changes to the generated HTML. It allows carving up a page into independent frames, which can be lazy-loaded and operated as independent components. Finally, it helps making partial page updates using just HTML and a set of CRUD-like container tags. These three techniques reduce the amount of custom JavaScript that many web applications need to write by an order of magnitude. And for the few dynamic bits that are left, Stimulus can be used.

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.

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.

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).

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.

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.

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.

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).

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.

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.

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.

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

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

The Redland RDF Library (librdf) provides the RDF API and triple stores.

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.

Rasqal is a C library that handles Resource Description Framework (RDF) query language syntaxes, query construction and execution of queries returning results as bindings, boolean, RDF graphs/triples or syntaxes. The supported query languages are SPARQL Query 1.0, SPARQL Query 1.1, SPARQL Update 1.1 (no executing) and the Experimental SPARQL extensions (LAQRS). Rasqal can write binding query results in the SPARQL XML, SPARQL JSON, CSV, TSV, HTML, ASCII tables, RDF/XML and Turtle/N3 and read them in SPARQL XML, RDF/XML and Turtle/N3.

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).
