GGMorse is a library that decodes Morse code in real-time from raw audio.

FLMSG is a Narrow Band Emergency Messaging Software (NBEMS). It can be used to manage, send and receive the forms that are used as basis for emergency communications data transfers (like ICS213 forms).

DVB-T dongles based on the Realtek RTL2832U can be used as a cheap software defined radio, since the chip allows transferring the raw I/Q samples to the host. rtl-sdr provides drivers for this purpose.

The default Linux driver managing DVB-T dongles as TV devices doesn't work for SDR purposes and clashes with this package. Therefore you must prevent the kernel from loading it automatically by adding the following line to your system configuration:

(kernel-arguments '("modprobe.blacklist=dvb_usb_rtl28xxu"))

To install the rtl-sdr udev rules, you must extend 'udev-service-type' with this package. E.g.: (udev-rules-service 'rtl-sdr rtl-sdr)

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).

gr-satellites is a GNU Radio out-of-tree module encompassing a collection of telemetry decoders that supports many different Amateur satellites.

This is a generic data receiver, mainly for decoding radio transmissions from devices on the 433 MHz, 868 MHz, 315 MHz, 345 MHz and 915 MHz ISM bands.

Dire Wolf is a Terminal Node Controller (TNC) for Amateur Packet Radio. It can perform as:

• APRS GPS tracker,

• Digipeater,

• Internet gateway (IGate)

• APRStt gateway

This is a library to decode DAB/DAB+.

The Ham Radio Control Library (Hamlib) is a project to provide programs with a consistent Application Programming Interface (API) for controlling the myriad of radios and rotators available to amateur radio and communications users.

This package provides a decoder for VDL Mode 2 messages used by planes.

Dream is a software implementation of a Digital Radio Mondiale (DRM) receiver.

Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax.

This library integrates the SASS stylesheet language into Ruby on Rails.

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.

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.

Propshaft is an asset pipeline library for Rails. It's built for an era where bundling assets to save on HTTP connections is no longer urgent, where JavaScript and CSS are either compiled by dedicated Node.js bundlers or served directly to the browsers, and where increases in bandwidth have made the need for minification less pressing. These factors allow for a dramatically simpler and faster asset pipeline compared to previous options, like Sprockets.

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

ActionMailbox receives and processes incoming emails in Rails applications.

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.

Compose, deliver, receive, and test emails using the controller/view pattern. Including support for multipart email and attachments.

ActionPack provides conventions for building and testing MVC web applications. These work with any Rack-compatible server.

GlobalID provides a way to generate URIs from a model in Ruby that uniquely identify it.

ActiveStorage integrates file storage services with Rails applications, allowing files to be attached to ActiveRecord models.

This package provides a toolkit for building modeling frameworks like Active Record. ActiveSupport handles attributes, callbacks, validations, serialization, internationalization, and testing.
