Google Code-in

Google Code-in (GCI) is an annual programming competition hosted by Google Inc. that allows pre-university students to complete tasks specified by various, partnering open source organizations. The contest was originally the Google Highly Open Participation Contest, but in 2010, the format was modified into its current state. Students that complete tasks win certificates and T-shirts. Each organization also selects two grand prize award winners who will earn a trip to Google's Headquarters located in Mountain View, California.[1][2]

The program began as Google Highly Open Participation Contest during 2007-2008 aimed at high school students. The contest was designed to encourage high school students to participate in open source projects.[3] . In 2010, the program was modified into Google Code-in. After the 2014 edition, the Google Melange was replaced by a separate website for Google Code-in.[4] Mauritius, an African country, participated for the first time in 2016, and was noticed for its strong debut[5] and in 2017, produced its first Grand Prize winner [6].

The contest was open to students thirteen years of age or older who were then currently enrolled in high school (or equivalent pre-university or secondary school program). Prizes offered by Google included a contest T-shirt and a participation certificate for completing at least one task and US$100 for every three tasks completed to a maximum of US$500. There was a grand prize of a trip to the Google headquarters for an award ceremony. Each participating open source project selected one contestant to receive the grand prize, for a total of 10 grand prize winners.[7]

Google partners with certain open source organizations, all of which have had previous experience working with Google open source programs like Google Summer of Code. These organizations come up with "bite-sized" tasks that are self-contained, designed for pre-university students to complete. When the contest begins, students can register and claim tasks. Once claimed, students will have a set period of time to complete the task and can receive help from the mentor and the organization's community. Students may ask for deadline extensions if needed.[16]

Free software license

A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder (usually the author) of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a license is free software (or free and open-source software) as conferred by the copyright holder. Free-software licenses are applied to software in source code and also binary object-code form, as the copyright law recognizes both forms.

GNU General Public License

The GNU General Public License (GNU GPL or GPL) is a widely-used free software license, which guarantees end users the freedom to run, study, share and modify the software. The license was originally written by Richard Stallman of the Free Software Foundation (FSF) for the GNU Project, and grants the recipients of a computer program the rights of the Free Software Definition. The GPL is a copyleft license, which means that derivative work can only be distributed under the same license terms. This is in distinction to permissive free software licenses, of which the BSD licenses and the MIT License are widely-used examples. GPL was the first copyleft license for general use.

Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software domain. Prominent free-software programs licensed under the GPL include the Linux kernel and the GNU Compiler Collection (GCC). David A. Wheeler argues that the copyleft provided by the GPL was crucial to the success of Linux-based systems, giving the programmers who contributed to the kernel the assurance that their work would benefit the whole world and remain free, rather than being exploited by software companies that would not have to give anything back to the community.In 2007, the third version of the license (GNU GPLv3) was released to address some perceived problems with the second version (GNU GPLv2) that were discovered during its long-time usage. To keep the license up to date, the GPL license includes an optional "any later version" clause, allowing users to choose between the original terms or the terms in new versions as updated by the FSF. Developers can omit it when licensing their software; for instance the Linux kernel is licensed under GPLv2 without the "any later version" clause.

Many LUGs encompass FreeBSD and other free-software / open source Unix-based operating systems.


Mauritius ( (listen); French: Maurice, Creole: Moris [moʁis]), officially the Republic of Mauritius (French: République de Maurice, Creole: Repiblik Moris), is an island nation in the Indian Ocean about 2,000 kilometres (1,200 mi) off the southeast coast of the African continent. The country includes the islands of Mauritius and Rodrigues, 560 kilometres (350 mi) east of Mauritius, and the outer islands of Agaléga and St. Brandon. The islands of Mauritius and Rodrigues form part of the Mascarene Islands, along with nearby Réunion, a French overseas department. The area of the country is 2,040 km2 (790 sq mi). The capital and largest city is Port Louis. The island is widely known as the only known home of the dodo, which, along with several other avian species, was made extinct by human activities relatively shortly after the island's settlement.

Formerly a Dutch colony (1638–1710) and a French colony (1715–1810), Mauritius became a British colonial possession in 1810 and remained so until 1968, the year in which it attained independence. The British Crown colony of Mauritius once included the current territories of Mauritius, Rodrigues, the outer islands of Agaléga, St. Brandon, Chagos Archipelago, and Seychelles. The Mauritian territories gradually devolved with the creation of a separate colony of Seychelles in 1903 and the excision of the Chagos Archipelago in 1965. The sovereignty over the Chagos Archipelago is disputed between Mauritius and the United Kingdom. The UK excised the archipelago from Mauritian territory in 1965, three years prior to Mauritian independence. The UK gradually depopulated the archipelago's local population and leased its biggest island, Diego Garcia, to the United States. Access to the Chagos Archipelago is prohibited to casual tourists, the media, and its former inhabitants. Mauritius also claims sovereignty over Tromelin Island from France.

The people of Mauritius are multiethnic, multi-religious, multicultural and multilingual. The island's government is closely modelled on the Westminster parliamentary system, and Mauritius is highly ranked for democracy and for economic and political freedom. The Human Development Index of Mauritius is the second highest in Africa. Along with the other Mascarene Islands, Mauritius is known for its varied flora and fauna, with many species endemic to the island.

Mauritius is the only country in Africa where Hinduism is the largest religion. The administration uses English as its main language.

XBT Tracker

XBT Tracker is a free and open-source BitTorrent tracker written in C++ by Olaf van der Spek. Because it is a "pure" tracker, it does not offer a frontend. The software is specifically designed to consume few resources, while maintaining a high level of performance. It listens on port 2710 by default. XBT Tracker uses MySQL, but it can also run without it.

The project was hosted at Sourceforge until it moved to Google Code in 2011. In 2015, source moved to GitHub.
