Nov 17, 2016 - The Most Important Song in my Life

No explanation, really. At the time — 1991, I think — I was stuck in a bus for two days. It moved forward, yes, but ever so slowly. All the time, all I had was my Sony Walkman and one single tape — “Goodbye Yellow Brick Road” by Elton John. Also, I only had two batteries. I also had one book, “Fear and Loathing in the Campaign Trail” by Hunter Thompson. The batteries ran out, I read the book twice. What a miserable time. What a wonderful moment.

OK, so there was some explanation.

Oct 7, 2016 - More IT Girls!

The more you know: More IT Girls

Why encourage girls to go into a science, tech, engineering or math career? The U.S. will need more than 1.5 million engineers and computing professionals in the next 10 years. Enough “it girls.” More IT Girls!

Oct 3, 2016 - Open-sourced, at last

I have finally let go of my ISP, after… many years of hosting. They (a2hosting) served me well, but now I have to try things on my own and practice what I preach. Exciting times, yes. I wish this had happened 20 years ago, or better yet, 30.

Aug 2, 2016 - Fleetwood Mac: Rhiannon

Somewhere along the way, a friend of mine posted this video on Facebook, and I stopped disliking the song Rhiannon, that for whatever long-forgotten reason I disliked.

I think it was because it was featured in the TV-Guide channel of whatever cable system I had in the late 80s that kept on playing it over and over again. Welcome to the time machine.

EDIT: The truth is that I would probably still hate this song if tested under the same circumstances, i.e. repetead ad nauseum while playing spades into the wee hours of the night with my roomate, with no real possibility of escaping the duldrum that was that apartment and contacting the outside world. However, finally watching this live rendition reminded me just how much I liked Stevie Nicks, perforated nose and all, and what a great time it must have been to have witnessed Fleetwood Mac at this point. The time machine is a real thing, however.
