Briar (software)
Briar is an open-source software communication technology, intended to provide secure and resilient peer-to-peer communications with no centralized servers and minimal reliance on external infrastructure. Messages can be transmitted through Bluetooth, WiFi, over the internet via Tor or removable storage, such as USB sticks. All communication is end-to-end encrypted. Relevant content is stored in encrypted form on participating devices. Long-term plans for the project include support for distributed applications such as crisis mapping and collaborative document editing. The initial target audience for Briar includes "activists, journalists and civil society" with plans to make the system "simple enough to help anyone keep their data safe." As the ability to function in the absence of internet infrastructure may also make the project valuable to disaster response and aid organizations, the developers are working with the Open Humanitarian Initiative and Taarifa. Ultimately, the deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manjaro
Manjaro ( ) is a free and open-source Linux distribution based on the Arch Linux operating system that has a focus on user-friendliness and accessibility. It uses a rolling release update model and Pacman as its package manager. It is developed mainly in Austria, France and Germany. History Manjaro was first released on July 10, 2011. By mid 2013, Manjaro was in the beta stage, though key elements of the final system had all been implemented such as: a GUI installer (then an Antergos installer fork); a package manager (Pacman) with its choice of frontends; Pamac (GTK) for Xfce desktop and Octopi ( Qt) for its Openbox edition; MHWD (Manjaro Hardware Detection, for detection of free & proprietary video drivers); and Manjaro Settings Manager (for system-wide settings, user management, and graphics driver installation and management). GNOME Shell support was dropped with the release of version 0.8.3 in 2012. However, efforts within Arch Linux made it possible to restart the Cinn ...

Communication Software
Communication software is used to provide remote access to systems and exchange files and messages in text, audio and/or video formats between different computers or users. This includes terminal emulators, file transfer programs, chat and instant messaging programs, as well as similar functionality integrated within MUDs. The term is also applied to software operating a bulletin board system, but seldom to that operating a computer network or Stored Program Control exchange. History E-mail was introduced in the early 1960's as a way for multiple users of a time-sharing mainframe computer to communicate. Basic text chat functionality has existed on multi-user computer systems and bulletin board systems since the early 1970s. In the 1980s, a terminal emulator was a piece of software necessary to log into mainframes and thus access e-mail. Prior to the rise of the Internet, computer files were exchanged over dialup lines, requiring ways to send binary files over communication syste ...

Bridgefy
Bridgefy is a Mexican software company with offices in Mexico and California, the United States, dedicated to developing mesh-networking technology for mobile apps. It was founded circa 2014 by Jorge Rios, after conceiving the idea while participating in a tech competition called StartupBus. Bridgefy's smartphone ad hoc network technology, apparently using Bluetooth Mesh, is licensed to other apps. The app gained popularity during protests in different countries since it can operate without Internet, using Bluetooth instead. Aware of the security issues of not using cryptography and the criticism surrounding it, Bridgefy announced in late October 2020 that they adopted the Signal protocol, in both their app and SDK, to keep information private, though security researchers have demonstrated that Bridgefy's usage of the Signal Protocol is insecure. Usage The app gained popularity as a communication tactic during the 2019–2020 Hong Kong protests and Citizenship Amendment Act prot ...

Tox (protocol)
Tox is a peer-to-peer instant-messaging and video-calling protocol that offers end-to-end encryption. The stated goal of the project is to provide secure yet easily accessible communication for everyone. A reference implementation of the protocol is published as free and open-source software under the terms of the GNU GPL-3.0-or-later. History The initial commit to GitHub was pushed on June 23, 2013, by a user named irungentoo. Pre-alpha testing binaries were made available for users from February 3, 2014, onward. On July 12, 2014, Tox entered an alpha stage in development and a redesigned download page was created for the occasion. Features Encryption of traffic Users are assigned a public and private key, and they connect to each other directly in a fully distributed, peer-to-peer network. Users have the ability to message friends, join chat rooms with friends or strangers, voice/video chat, and send each other files. All traffic over Tox is end-to-end encrypted using t ...

Serval Project
The Serval Project (often referred to as Serval) is a project financed by the Shuttleworth Foundation, as well as various other organisations and accepting individual donations. It is headquartered at Flinders University in Adelaide, Australia. The project aims to develop technology that can be used to create direct connections between cellular phones through their Wi-Fi interfaces, without the need of a mobile phone operator. The technology allows for live voice calls whenever the mesh is able to find a route between the participants. Text messages and other data can be communicated using a store and forward system called Rhizome, allowing communication over unlimited distances and without a stable live mesh connection between all participants. The Serval Project includes a collaborate mapping application intended to support disaster relief and recovery efforts. A "mesh extender" is being developed, which establishes a short range Serval mesh over WiFi and joins it with other more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jami (software)
Jami (formerly GNU Ring, SFLphone) is a SIP-compatible distributed peer-to-peer softphone and SIP-based instant messenger for Linux, Microsoft Windows, OS X, iOS, and Android. Jami was developed and maintained by the Canadian company Savoir-faire Linux, and with the help of a global community of users and contributors, Jami positions itself as a potential free Skype replacement. Jami is free and open-source software released under the GNU GPL-3.0-or-later. In November 2016, it became part of the GNU Project. Two account types are currently available, and many of each type can be configured concurrently. Both types offer similar features including messaging, video and audio. The account types are SIP and Ring. A SIP account enables the Jami softphone to connect to a standard SIP server and a Ring account can register (or use an account set up) on the decentralised Jami network which requires no central server. By default, Jami uses a OpenDHT node maintained by Savoir-faire Li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smartphone Ad Hoc Network
Smartphone ad hoc networks (SPANs; also ''smart phone ad hoc networks'') are wireless ad hoc networks that use smartphones. Once embedded with ad hoc networking technology, a group of smartphones in close proximity can together create an ad hoc network. Smart phone ad hoc networks use the existing hardware (primarily Bluetooth and Wi-Fi) in commercially available smartphones to create peer-to-peer networks without relying on cellular carrier networks, wireless access points, or traditional network infrastructure. Wi-Fi SPANs use the mechanism behind Wi-Fi ad-hoc mode, which allows phones to talk directly among each other, through a transparent neighbor and route discovery mechanism. SPANs differ from traditional hub and spoke networks, such as Wi-Fi Direct, in that they support multi-hop routing (ad hoc routing) and relays and there is no notion of a group leader, so peers can join and leave at will without destroying the network. Spans are useful under circumstances when the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Technology Fund
The Open Technology Fund (OTF) is an American nonprofit corporation that aims to support global Internet freedom technologies. Its mission is to "support open technologies and communities that increase free expression, circumvent censorship, and obstruct repressive surveillance as a way to promote human rights and open societies." As of November 2019, the Open Technology Fund became an independent nonprofit corporation and a grantee of the U.S. Agency for Global Media. Until its formation as an independent entity, it had operated as a program of Radio Free Asia. History The Open Technology Fund was created in 2012 as a pilot program within Radio Free Asia. Under U.S. Secretary of State Hillary Clinton, the State Department adopted a policy of supporting global internet freedom initiatives. At this time, RFA began looking into technologies that helped their audiences avoid censorship and surveillance. Journalist Eli Lake argued that Clinton's policy was "heavily influenced by the ...

PostmarketOS
postmarketOS (abbreviated as pmOS) is an operating system primarily for smartphones, based on the Alpine Linux distribution. postmarketOS was launched on 26 May 2017 with the source code available on GitHub before migrating to GitLab in 2018. It is capable of running different X and Wayland based user interfaces, such as Plasma Mobile, MATE, GNOME 3, and XFCE; later updates added support for Unity8 and Phosh. It is also capable of running Docker, if the device specific kernel has cgroups and relevant configs enabled. The project aims to provide a ten-year lifecycle for smartphones. Architecture Unlike many other projects porting conventional Linux distributions to Android phones, postmarketOS does not use the Android build system or userspace. Each phone has only one unique package, and flashable installation images are generated using the pmbootstrap tool. The project intends to support the mainline Linux kernel on all phones in the future, instead of the often outdated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
