Reader Adam Rice writes in to let us know about 'vm_stat', a commandline utility that comes with Darwin to give some info about virtual memory. Thanks Adam!
Also, from ETCon yesterday I picked up a Darwin CD from the BSD Mall guys, it might give new life to this old PowerMac 7500 I have. Sure, you can build a Mac bootable Darwin CD-ROM yourself, or you can support the community a bit and buy one. It's also x86 bootable. I'll keep everybody updated.
