Poseidon Linux
Poseidon Linux is Linux distribution, a complete operating system, originally based on Kurumin, now based on Ubuntu. It is developed and maintained by a team of young scientists from the Rio Grande Federal University in Rio Grande do Sul, Brazil, and the MARUM institute in Germany. Naming. The name Poseidon was chosen after the "God of the seas" in Greek mythology, since a large number of oceanologists have been involved in the development of the system. History. The 3.x family was pre-presented in 2008 at the 9th Free Software International Forum (FISL9.0), and received compliments from numerous  users, free software enthusiasts, and the Linux community in general, including from Jon "maddog" Hall of Linux International. Poseidon 3.2 was officially released in the IV Brazilian Oceanography Congress, that took place in May 2010 in Rio Grande, Brazil. For version 4.0, the project changed the base distribution from Knoppix/Kurumin to Ubuntu. This was due to the wide acceptance of Poseidon outside the Portuguese-speaking scientific community, and because of the shut-down of the Kurumin project. The Ubuntu-based releases allow the installation in Portuguese, Spanish, English, German, French, Greek, and other languages. The development team stated that  after Poseidon 5.0, the distribution would focus on bathymetry, seafloor mapping, and GIS software. Many of the bundled CAD and scientific programs were removed, but may be separately available for download from compatible repositories. The current version of Poseidon is 8.0, and is based on 32-bit and 64-bit Ubuntu 16.04 LTS. Features. Throughout its release history, the distro has contained many free software programs used in science and engineering, such as the Fortran programming language, Kile and Lyx for scientific writing, numerical modeling, 2D/3D/4D visualization, statistics, CAD, genetics, bio-informatics, and several tools that support GIS and mapping . Additionally, LibreOffice, web browsers, and multimedia packages are included.
