Cuba launched Linux Nova last week at a Havana computer conference on “technological sovereignty.” The government feels that Microsoft systems are a potential threat to their country because they say U.S. security agents have access to codes. Besides that, they say that the trade embargo makes it difficult to get the software legally and update it. Dean of the School of Free Software, Hector Rodriguez, claims that about 20% of the computers are currently using Linux but feels that that figure could climb to more than 50% in 5 years.
