As a general rule, the kernel is supposed to use the least amount of CPU time possible; any time taken by the kernel is not available for the applications the user actually wants to run. As a result, not a lot of thought has gone into optimizing the execution of kernel-side...

It has been nearly 13 years since Jeff Garzik proclaimed that Linux was 'proving its superiority in the area of crappy wireless (WiFi) support'. Happily, the situation has improved somewhat since then, but that doesn't mean that things can't get better yet. During the...

There is a whole new set of PostgreSQL releases out there, the main purpose of which is to include an important security fix. 'Using a purpose-crafted trigger definition, an attacker can run arbitrary SQL statements with superuser privileges when a superuser runs...

A 'joke' in the glibc manual—targeting a topic that is, at best, sensitive—has come up for discussion on the glibc-alpha mailing list again. When we looked at the controversy in May, Richard Stallman had put his foot down and a patch removing the joke—though opinions...
