New i386 Interrupt and SMP Code on FreeBSD

FreeBSD's John Baldwin says he will be committing some very significant changes to the i386 interrupt and SMP code for FreeBSD. Some new features include runtime selection of using the I/O APICs or the AT PICs to route interrupts; SMP can now be enabled in GENERIC kernel and the SMP kernel config is no longer necessary. His new code can largely be pulled over to amd64 to support APICs and SMP based on that architecture.

From Monolithic to Grid: a Brief History of Computing

How did we get from there to here? The history of computing is marked by ages. In each age, the basic design of how we work with computers changes. Many people probably think we're in the brave new Internet age at this time, but considering the nature of computing, we're likely just at an intermediary stage. We're just now peeking into the next age -- the age of the truly distributed computing system --the coming of the grid.

Regarding Microsoft’s New CLI

In one of the most overlooked cool things at the PDC, the new Command Shell that will be in Longhorn blew me away when I saw it.
