Following last month’s closure of Denver’s Rocky Mountains News, Seattle lost one of city’s two dailies as the Seattle Post-Intelligencer published its last issue today after 146 years in business. As a news junkie, I’m saddened at the loss of these institutions.

I heard a brief segment on the radio this morning noting that today marks the 40th anniversary of the computer mouse. It is… kind of. The mouse had its first public demonstration on this date in 1968 at the Fall Joint Computer Conference in San Francisco. Of course the development of the mouse began several years earlier as noted by numerous sources such as the Inventors of the Modern Computer and the Wikipedia article on “Mouse (computing)“. Take a look at some photos and drawings of the the very first mouse; it was quite a boxy little guy. YouTube has clips of the entire demonstration given by Doug Engelbart that day including a segment focused specifically on the “pointing device”; it’s a fascinating glimpse into computing history. The San Francisco Chronicle has a nice write-up marking the event. I remember the first time I saw a mouse in the Fall of 1983 in the dim, cold, raised-floor data entry room at Xerox University Microfilms in Ann Arbor. Mice didn’t become available as retail accessories until 1985 but Logitech International alone claims they had shipped over one billion mice by the end of 2004.

I was surprised –I’m not sure why– to read this morning that PC Magazine is ceasing its print version and becoming an online-only publication following in the steps of InfoWorld that became digital-only in April of ’07. I recall how I used to dig through every new issue trying to keep up with new applications and find still another geeky tip. Now I also realize I haven’t held the paper version in my hands for years while I look at PC Mag articles online often. I’m sure more old stand-bys will follow and go the Web-only route.

Too much mousing around in Excel has finally taken its toll on my poor index finger. The unfortunate digit was constantly sore and so swollen and stiff in the morning I couldn’t flex it at all. After a quick check and x-rays I was told I have “trigger finger” (Stenosing tenosynovitis) and was referred to a hand surgeon. After an injection of steroids the abused tendon seems good again.
