Hikarunix is a discontinued Linux distribution in Live CD format for the x86 architecture. It was based on Damn Small Linux, and last updated in 2005. The name is a portmanteau of the name of the manga and anime series Hikaru no Go and the Linux operating system kernel that Hikarunix is based on (which is a Unix-like operating system).
Hikarunix intended to provide a complete and ultra-portable environment for study and playing the game Go; from complete beginner (for whom Mori's "The Interactive Way To Go" 1 is included in addition to several books in PDF form, as well as a complete offline copy of Sensei's Library), to intermediate players (who can take advantage of a comprehensive joseki library and a collection of about 9500 challenging problems to work through called GoGrinder) to the expert (who can use the many online Go clients or study annotated games of Go masters, or even have their own games analyzed), all contained within an OS which can fit on a mini- or regular-sized CD or be installed to a harddrive, or be put onto a USB memory stick, so Go enthusiasts can use Hikarunix everywhere.
