I wish I had known about Octopart before reading this essay. I needed a part a couple weeks ago that I had no idea what the technical term for it was, my best guesses lead to things that were totally wrong, and the company that made it was now under a different name, and I could find no trace of the device or anything similar on their online catalog. Oh, and my predecessor, who bought the thing in the first place, 'picked it up at a garage sale'. The correct part from the correct (newly named) company was the first result from Octopart when I tried it just now.
