stability … boring old and simple stability

[xxx@yyy~]$ uptime 15:07:51 up <strong>505 days</strong>, 47 min, 14 users, load average: 0.39, 0.35, 0.19 [xxx@yyy~]$ uname -s Linux 43.6 mega-seconds. For the pair of 1.6 GHz CPUs that are in here, this is a combined 1.4 x 10^17 clock cycles. Or for the chemists among us … this is 0.23 micro-mole of clock cycles. […]

Frightening vulnerabilities …

There was a bit of a kerfluffle last week over weak random number generators and SSL for Debian and Debian based distributions. This vulnerability made it actually easy to crack a key generated with the OpenSSL code. Think about the basis for this risk. SSL is based upon hard to guess integers which are built […]
