The Cuban government this week launched its own Linux distribution,
called Nova.
"The Cuban government, under the auspices of the Universidad de las
Ciencias Informáticas (UCI), created Nova by spinning its own rev on
the Gentoo variant of Linux," writes The Register's Timothy Prickett
Morgan.
"Linux has become increasingly popular in South America, Africa and
Eastern Europe, where companies and citizens aren't able to afford all
of the latest Microsoft software," writes DailyTech's Michael
Barkoviak. "Furthermore, the open source software can be freely
distributed among friends and colleagues in these nations, which helps
it spread faster than Microsoft can."
