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

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

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.

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.

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.

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.

Liquid DSP is a digital signal processing (DSP) library designed specifically for software-defined radios on embedded platforms. The aim is to provide a lightweight DSP library that does not rely on a myriad of external dependencies or proprietary and otherwise cumbersome frameworks. All signal processing elements are designed to be flexible, scalable, and dynamic, including filters, filter design, oscillators, modems, synchronizers, complex mathematical operations, and much more.

This package provides support for sound card devices to the SoapySDR library. It also adds hamlib support, which provides basic gain and frequency controls for certain tuners which may be paired with an audio device.

Dump1090 is a Mode S decoder specifically designed for rtl-sdr devices. It can be used to decode the ADS-B signals that planes emit to indicate their position, altitude, speed, etc.

Minimodem is a command-line program which decodes (or generates) audio modem tones at any specified baud rate, using various framing protocols. It acts a general-purpose software FSK modem, and includes support for various standard FSK protocols such as Bell103, Bell202, RTTY, TTY/TDD, NOAA SAME, and Caller-ID.

SoapySDR is a library designed to support several kinds of software defined radio hardware devices with a common API.
