This package provides plugins to use MySQL or MariaDB as the database backend of an Orthanc DICOM server instead of SQLite.

(X)MedCon can be used to convert between different file formats used in medical imaging. The supported formats are ACR-NEMA 2.0, Analyze (SPM), Concorde/μPET, DICOM 3.0, CTI ECAT 6/7, NIfTI-1, Interfile 3.3, PNG, and GIF87a/89a. This package includes a command-line utility (medcon) and a GTK+ based GUI application (xmedcon).

Orthanc is a standalone DICOM server with a RESTful API and plugin mechanism for extending its functionality.

Mercury is a logic/functional programming language which combines the clarity and expressiveness of declarative programming with advanced static analysis and error detection features. Its highly optimized execution algorithm delivers efficiency far in excess of existing logic programming systems, and close to conventional programming systems. Mercury addresses the problems of large-scale program development, allowing modularity, separate compilation, and numerous optimization/time trade-offs.

NYACC is set of Guile modules for generating parsers and lexical analyzers. It provides sample parsers, pretty-printers using SXML trees as an intermediate representation, a decent C parser and an `FFI Helper' tool to help create Guile Scheme bindings for C-based libraries. It also provides (partially implemented) compilers based on these parsers to allow execution with Guile as extension languages.

GNU Mes--Maxwell Equations of Software--brings the Reduced Binary Seed bootstrap to Guix and aims to help create full source bootstrapping for GNU/Linux distributions. It consists of a mutual self-hosting Scheme interpreter in C and a Nyacc-based C compiler in Scheme and is compatible with Guile.

Mescc-tools is a collection of tools for use in a full source bootstrapping process. It consists of the M1 macro assembler, the hex2 linker, the blood-elf symbol table generator, the kaem shell, exec_enable and get_machine.

M2-Planet, the PLAtform NEutral Transpiler, when combined with mescc-tools, compiles a subset of the C language into working binaries with introspective steps in between. It is self-hosting and for bootstrapping it also has an implementation in the M1 macro assembly language. M2-Planet is built as Phase-5 of the full source bootstrapping process and is capable of building GNU Mes.

This module implements XEP-0357: Push Notifications.

Some platforms, notably Apple’s iOS and many versions of Android, impose limits that prevent applications from running or accessing the network in the background. This makes it difficult or impossible for an XMPP application to remain reliably connected to a server to receive messages.

In order for messaging and other apps to receive notifications, the OS vendors run proprietary servers that their OS maintains a permanent connection to in the background. Then they provide APIs to application developers that allow sending notifications to specific devices via those servers.

When you connect to your server with a client that requires push notifications, it will use this module to set up a “push registration”. When you receive a message but your device is not connected to the server, this module will generate a notification and send it to the push gateway operated by your application’s developers). Their gateway will then connect to your device’s OS vendor and ask them to forward the notification to your device. When your device receives the notification, it will display it or wake up the app so it can connect to XMPP and receive any pending messages.

Pidgin is a modular instant messaging client that supports many popular chat protocols.

Purple-Mattermost is a plug-in for Purple, the instant messaging library used by Pidgin and Bitlbee, among others, to access Mattermost servers.

HexChat lets you connect to multiple IRC networks at once. The main window shows the list of currently connected networks and their channels, the current conversation and the list of users. It uses colors to differentiate between users and to highlight messages. It checks spelling using available dictionaries. HexChat can be extended with multiple addons.

pounce is a multi-client, TLS-only IRC bouncer. It maintains a persistent connection to an IRC server, acting as a proxy and buffer for a number of clients.

Gajim-OpenPGP is a plugin that adds support for the OpenPGP Encryption to Gajim.

This module implements XEP-0363: it allows clients to upload files over HTTP.

OTR allows you to have private conversations over instant messaging by providing: (1) Encryption: No one else can read your instant messages. (2) Authentication: You are assured the correspondent is who you think it is. (3) Deniability: The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified. (4) Perfect forward secrecy: If you lose control of your private keys, no previous conversation is compromised.

qTox is a Tox client that follows the Tox design guidelines. It provides an easy to use application that allows you to connect with friends and family without anyone else listening in.
