This repository helps to setup a ready-to-use chatmail server comprised of a minimal setup of the battle-tested postfix smtp and dovecot imap services. The setup is designed and optimized for providing chatmail accounts for use by Delta Chat apps. Chatmail accounts are automatically created by a first login, after which the initially specified password is required for using them.
A disaster-resilient communications network powered by the sun.
When the critical infrastructure that so many of us take for granted goes away, how do we organize ourselves and our communities to respond?
If recent ecological disasters have demonstrated anything, it is the inadequacy of existing models and tools to provide efficient allocation of resources, access to emergency communications, and effective coordination of human effort. Few if any solutions exist that are off-grid, affordable, reliable, easily deployed, and openly standardized.
A collection of the best CLI/Ncurses software covering a wide range of categories from messaging, music, text editing and more.
RACE is an open source project aimed at developing technologies to provide metadata-anonymous, secure, and resilient messaging for users around the world. RACE provides anonymity by routing messages through an overlay network of volunteer servers using cryptographic algorithms that prevent a malicious subset of these servers from determining who is messaging whom. RACE uses specialized networking protocols to prevent connections between individual members of the network from being detected or blocked. RACE is built to run in a dockerized linux environment and on Android devices.

Centralized social media is harmful to society. We are building a gatekeeper-free decentralized system. Our mission is “social media done right”, to put people in control of their own identity and build the technology that would enable a shift to collaborative and intentional security models prioritizing active consent. To accomplish this, we will build a new architecture for the internet: removing the necessity of client-server architecture, replacing it with a participatory peer-centric model.
This is the home of the Spritely Goblins Distributed Programming platform - the core of our vision of a completely decentralised social internet.
Spritely’s technology is being released as free and open source software aiming for multiple programming language implementations and eventual open standardization. All of our work, ranging from decentralized identity, peer-to-peer user agents, decentralized social networks, encrypted and portable storage, and distributed object programming infrastructure is being built to enable a gatekeeper-free path where users and content are not tied to a specific server.

tio is a simple serial device tool which features a straightforward command-line and configuration file interface to easily connect to serial TTY devices for basic I/O operations. A simpler serial device tool for talking with serial TTY devices with less focus on classic terminal/modem features and more focus on the needs of embedded developers and hackers. tio was originally created to replace screen for connecting to serial devices when used in combination with tmux.
If it's a serial TTY device, it can talk to it. Sensible defaults (115200 8n1). Supports non-standard speeds, RS-485, multiple parity options.
Builds with Meson, for some reason. In the AUR.
TMTP is a new Internet protocol combining elements of email and the web. TMTP offers a simple, reliable, free, secure, decentralized method for messaging & correspondence & notification.
Online services lack a way to directly message their customers/members. Email (SMTP etc) is unreliable, insecure, and typically transits multiple third-party hosts between sender & recipient. (Email also has other painful problems!) Text messaging (SMS) is expensive. Some sites patch this gap by building & maintaining custom phone apps—at great cost.
The client and server are open source, subject to the terms of the Mozilla Public License, v2.0.

pure-python-otr is just what it says on the tin - it's an implementation of the Off-The-Record messaging protocol in pure Python, meaning that it doesn't hook any libraries that aren't written in Python. Useful for adding OTR support to communications software.
An archive website about coldwar infrastructure in the US. Has documentation about communications systems and facilities.
