Steve Friedl's Tech Tips

Steve Friedl's Tech Tips

This is a collection of tips on a very wide-ranging list of topics, some of which are not terribly technical. If I solved a problem that I thought others might need, I put it here so the search engines would pick them up. I hope they're helpful. Feedback and corrections are very much appreciated. Please forgive the Tech Tips that are incomplete.

Those who wish to reproduce these elsewhere will find that a polite request in advance always gets a positive response.
