HEADSUP: Alpha support is being retired in 7.0

[Rafael Ruiz]

Hi!
In this paper says that Chinese military works on their own cloned Alpha EV8
/ EV9 processors, and they running COSIX (Chinese Tru64 UNIX whose source
code Compaq gave to the China sometime ago, plus EV8 etc plans that might
have leaked out of the US).

Please, see http://www.theinquirer.net/?article=4266
