GNU GPL
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domain. Promi ...

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 Wi-Fi and joins it with other mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenBTS
OpenBTS (Open Base Transceiver Station) is a software-based GSM access point, allowing standard GSM-compatible mobile phones to be used as SIP endpoints in Voice over IP (VoIP) networks. OpenBTS is open-source software developed and maintained by Range Networks. The public release of OpenBTS is notable for being the first free-software implementation of the lower three layers of the industry-standard GSM protocol stack. It is written in C++ and released as free software under the terms of version 3 of the GNU Affero General Public License. Open GSM infrastructure OpenBTS replaces the conventional GSM operator core network infrastructure from layer 3 upwards. Instead of relying on external base station controllers for radio resource management, OpenBTS units perform this function internally. Instead of forwarding call traffic through to an operator's mobile switching center, OpenBTS delivers calls via SIP to a VOIP soft switch (such as FreeSWITCH or yate) or PBX (such as ...

Optimized Link State Routing Protocol
The Optimized Link State Routing Protocol (OLSR) is an Internet Protocol, IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol, which uses ''hello'' and ''topology control'' (TC) messages to discover and then disseminate link state information throughout the mobile ad hoc network. Individual nodes use this topology information to compute next hop destinations for all nodes in the network using shortest hop forwarding paths. Features specific to OLSR Link-state routing protocols such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) elect a ''designated router'' on every link to perform flooding of topology information. In wireless ad hoc networks, there is different notion of a link, packets can and do go out the same interface; hence, a different approach is needed in order to optimize the flooding process. Using Hello mes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Release Life Cycle
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. Pre-alpha refers to the early stages of development, when the software is still being designed and built. Alpha testing is the first phase of formal testing, during which the software is tested internally using White-box testing, white-box techniques. Beta testing is the next phase, in which the software is tested by a larger group of users, typically outside of the organization that developed it. The beta phase is focused on reducing impacts on users and may include usability testing. After beta testing, the software may go through one or more release candidate phases, in which it is refined and tested further, before the final version is released. Some software, particularly in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yahoo News
Yahoo News (stylized as Yahoo! News) is a news website that originated as an internet-based news aggregator by Yahoo. The site was created by Yahoo software engineer Brad Clawsie in August 1996. Articles originally came from news services such as the Associated Press, Reuters, Fox News, Al Jazeera, ABC News, ''USA Today'', CNN and BBC News. In 2000, Yahoo News launched pages tracking the content on the site that was most viewed and most shared by email. The "most emailed" page in particular was noted as an innovation in online news aggregation. Yahoo News allows users to comment on articles. Between late 2006 and early 2010, comments were disabled in part due to moderation challenges. By 2011, Yahoo had expanded its focus to include original content, as part of its plans to become a major media organization. Veteran journalists (including Walter Shapiro and Virginia Heffernan) were hired, while the website had a correspondent in the White House press corps for the first time ...
