John Carter wrote about the Tech Tuesday column and we posted it here on October 25 and November 8, but complaining about how difficult it was to navigate that column brought up a good suggestion from John. He sends us to the duckduckgo website for a nice list.
Further fiddling around I noticed the big word ARCHIVE on the Tech Tuesday home page. Clicking on that word brought up a huge treasure. Up comes 1 - 1/4 inch squares that contain the first 25 words, or so, of that day's posting. I scrolled down as far as November 2009 and hadn't come to the end yet. By entering in a key word in the tiny search box at the top the computer will do the work of finding every instance where the word appears in the little squares. John did send a comment which is posted on the first article after the last post that tells how operating systems work.
