The QtX11Extras module includes the library to access X11 from within Qt 5.

This package provides the asynchronous RPC client-server framework and message specification for Rigetti Quantum Cloud Services (QCS). It implements an efficient transport protocol by using ZeroMQ (ZMQ) sockets and MessagePack (msgpack) serialization.

This is the official Quil-Lang Quantum Virtual Machine (QVM), a flexible and efficient simulator for Quil.

Quil is the quantum instruction language, originally developed at Rigetti Computing. In Quil quantum algorithms are expressed using Quil's standard gates and instructions

The Racket BC (``before Chez'' or ``bytecode'') implementation was the default before Racket 8.0. It uses a compiler written in C targeting architecture-independent bytecode, plus a JIT compiler on most platforms. Racket BC has a different C API than the current default runtime system, Racket CS (based on ``Chez Scheme'').

This package is the normal implementation of Racket BC with a precise garbage collector, 3M (``Moving Memory Manager'').

The Racket CS implementation, which uses ``Chez Scheme'' as its core compiler and runtime system, has been the default Racket VM implementation since Racket 8.0. It performs better than the Racket BC implementation for most programs. On systems for which Racket CS cannot generate machine code, this package uses a variant of its ``portable bytecode'' backend specialized for word size and endianness.

Using the Racket VM packages directly is not recommended: instead, install the racket-minimal or racket packages.

This variant of the Racket BC (``before Chez'' or ``bytecode'') implementation is not recommended for general use. It uses CGC (a ``Conservative Garbage Collector''), which was succeeded as default in PLT Scheme version 370 (which translates to 3.7 in the current versioning scheme) by the 3M variant, which in turn was succeeded in version 8.0 by the Racket CS implementation.

Racket CGC is primarily used for bootstrapping Racket BC [3M]. It may also be used for embedding applications without the annotations needed in C code to use the 3M garbage collector.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The ``minimal Racket'' distribution includes just enough of Racket for you to use raco pkg to install more. Bundled packages, such as the DrRacket IDE, are not included.

Racket is a general-purpose programming language in the Scheme family, with a large set of libraries and a compiler based on Chez Scheme. Racket is also a platform for language-oriented programming, from small domain-specific languages to complete language implementations.

The main Racket distribution comes with many bundled packages, including the DrRacket IDE, libraries for GUI and web programming, and implementations of languages such as Typed Racket, R5RS and R6RS Scheme, Algol 60, and Datalog.

Zuo is a tiny Racket with primitives for dealing with files and running processes. It comes with a make-like embedded DSL, which is used to build Racket itself.

Zuo is a Racket variant in the sense that program files start with #lang, and the module path after #lang determines the parsing and expansion of the file content. That's how the make-like DSL is defined, and even the base Zuo language is defined by layers of #langs. One of the early layers implements macros.

Fldigi is a software modem for amateur radio use. It is a sound card based program that is used for both transmitting and receiving data by connecting the microphone and headphone connections of a computer to some radio hardware.

Inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

Gqrx is a software defined radio (SDR) receiver implemented using GNU Radio and the Qt GUI toolkit.

Flrig is a transceiver control program for amateur radio use. It provides computer aided control of various radios using a serial or USB connection.

KochMorse is a simple morse-code tutor using the Koch method.

This is a GNU Radio block to correct IQ imbalance in quadrature receivers. It's composed of two main block:

• Fix: Given a phase and amplitude error, it will correct a complex signal.

• Optimize: Attempts to auto-detect the phase and amplitude error to feed to the fix block above.

The soapy_power obtains the power spectrum from SDR devices that are supported by the SoapySDR library.

This package includes the libcsdr library of DSP functions for SDRs, and the csdr command line program that can be used to build simple signal processing flow graphs.

This package contains a library and command line utilities for controlling the BladeRF Software Defined Radio (SDR) over USB. To install the bladerf udev rules, you must extend 'udev-service-type' with this package. E.g.: (udev-rules-service 'bladerf bladerf).

This a C-language library for common DSP (Digital Signal Processing) primitives for SDR (Software Defined Radio).

The Universal Radio Hacker (URH) is a complete suite for wireless protocol investigation with native support for many common Software Defined Radios.
