This is the new home for Technical Musings, the technical blog I have maintained for a number of years. Virtually all the posts prior to 2022 were ported directly from the old github.io site. I also addd a bunch of news items (from my old personal website) that are now curated under the News category. While my old github.io blog will be perserved for posterity, all current/future updates will occur here.

West Point TEDx Talk - Tomorrow's Personal Computer

On February 1, 2018 I had the fantastic opportunity to give a talk at TEDx West Point. I was selected to represent the Academy in November of 2017 at the event. It was a huge honor, since most of the selected speakers were cadets (by design), and very few faculty were selected. Today, my TEDx talk was finally posted! A link appears below. It is titled “Tomorrow’s Personal Computer”, and makes the argument why computers must stay personal in order to inspire the next generation of computer scientists.

PicoCluster Review (Raspberry Pi 3B+)

Note: this is a post I created in 2018. I got distracted by some other things and forgot to fully update it. I made some further updates when I discovered the issues in 2021. Sorry! This is the second cluster system that I’m exploring this summer. In recent years a lot of commercial microcluster solutions have started popping up. Last post, I reviewed PiRacks. In this post, I will review Picocluster.

PiRacks Review (Raspberry Pi 3B+)

Another summer, and I’m exploring building yet another cluster. Back in 2014 when I started designing my cluster materials, there weren’t a lot of great options for cases for SBC-based microclusters. So I (and Frank Blackmon, our department tech) designed some for the parallella and the raspberry pi. They were pretty great, and I’ve used them extensively for many clusters that I’ve built in the last four years. I’ve presented some of the cluster designs at SIGCSE back in 2015 and 2016.

Raspberry Pi Cluster - Image Creation with MPI

I have a few more posts in mind for this summer, but I wanted to create this one while the information was still fresh in my head. Imagine my dismay when I discovered that the original Raspberry Pi cluster tutorial created by Dr. Simon Cox at the University of South Hampton no longer seems to exist. This has always been to me the de-facto go-to tutorial for creating Raspberry Pi images.

HERS Leadership Institute

Earlier this year, I was selected to participate in the 2018 HERS Leadership Institute at the University of Denver. The Higher Education Resource Services (HERS) was founded in 1972 to help provide leadership training and opportunities for women in higher education. Since 1976, the HERS Institute has been providing summer leadership training experiences for women faculty. Over 5,000 women faculty and staff have attended the HERS Leadership institute over the last 40 years.
