Minneapolis Skyway System

Last year I created a web page about the Minneapolis Skyway System. It's both factual and opinionated. Perhaps you will find it interesting.

Here are some random pictures I took: pics


I am retired now but my most recent work involved a parallel programming language called Chapel. It has nothing to do with religion, but people love to make jokes about going to the Chapel.

Here are articles by Jonathan Dursi ( about Chapel: Chapel Articles including the article "HPC is dying, and MPI is killing it" that is interesting and provides a perspective I share - and it mentions Chapel (I am biased though).

I was interviewed about Chapel just before I retired: online interview

2020 Biking Statistics

Completed the first ride of the 2020 season on 8-March-2020. I bought a new Trek Domane SL-5 OCLV carbon fiber bicycle in February. My beloved Bianchi San Lorenzo developed a crack in the frame and I had to junk it. *tear in eye* I've completed all the steps of grief and loss and arrived at acceptance. It's nice to be thinking about riding again. Now we are experiencing the COVID-19 crisis and biking seems like a good way to get outside but not have to worry about being around other people that might be infected. I just have to avoid the crowded bike paths on nice days. Stay at home and be safe. This has also been a time of social unrest as first, there were demonstrations against the State of Minnesota's stay at home rules, and more importantly, violent demonstrations against the murder of George Floyd by a Minneapolis Police Officer. Watching the video of George's murder is as difficult thing to watch as I've ever seen. Black Lives Matter. July was a mixture of really hot weather and stretches of really nice biking weather. August was also a mixture of hot and beautiful weather but the beautiful days were incredible. September presented an entire month of fabulous biking weather. I reached my goal of 5000 miles in a single biking season. Retirement sure helps one find more time for riding!
