unseen, the Power Macintosh G3 that hosted manoverboard.org for six years, running (at the end) Mandrake Linux 8.x, failed on 21 December 2005. After an hour or two of pushing the power button in hope of persuading it, I at last concluded unseen was gone for good. 
 
Fortunately, I had another Power Mac, towerofart, a dual-G4. I'm also an Apple Developer Connection Select member, which entitles me to a free license for Mac OS X Server. I had the machine reformatted and mail service restored within a few hours, and went to bed just after four in the morning. 
 
My midnight installation was of version 10.3 of Mac OSXS; the 10.4 download is in the form of a DVD-ROM image, and I don't have a DVD burner. I had an installation DVD the next afternoon, and upgraded to 10.4. That version of Mac OSXS includes a weblog application, and forward inertia had me activate it and start posting.  
 
As my book, Step into Xcode, is due out in a few weeks, I expect this will be a good way to process errata. We'll see.
