"You won't be carrying a calculator with you everywhere you go." A friend of mine recalled his math teacher telling him that. I'm sure we've all heard this or even have said it before ourselves.

Nothing like your back going out to make you feel old. Happens to me every few years, and comes out of the blue. Last time it was when I was brushing my teeth. This time it was tying my shoes. Anyway, after a hospital visit I was told to take a couple of days … Continue Reading ››

I went to a workshop recently that mentioned the concept of "shelfware"--software you buy that ends up on a "shelf," not used. Of course, these days that shelf might be virtual.
This got me to thinking about iPad apps I've purchased and then minimally or never used, and why. About a month ago, I bought a … Continue Reading ››
