The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

A serious lack of power

I walked into the Computer Room at Chez Boca to a squealing UPS, but unlike last time this happened the computers were still powered up. I shutdown both computers and decided to deal with them after lunch. There wasn't much else I could do at that point, seeing how the power was out for our entire neighborhood.

After lunch, the power was restored, so I went to power up the Linux box and … it didn't come on.

XXXXX­XXXXX­XXXXX­XXXXX­XXXXX­XXX!

I checked the internal cables to make sure none have come loose, evicted multiple dust bunnies, and even changed the CMOS battery just to be sure. But nothing I did made the Linux box power up.

I called my friend Tom Singkornrat (not only is he wise in the way of hardware, but he lives less than a mile away) and he said that it could be one of two possible reasons—it could be a bad power supply, or it could be a bad mother board. He had a spare power supply I could try. Why not?

The only difficult part of the whole procedure was unscrewing the old power supply from the case. Other than that, the new power supply fit right in and it powered right up. Great! But for some reason the keyboard wasn't working …

Update later today …

I found the issue with the keyboard.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
