Software Engineering Takeaways
I had a great time this spring teaching a software engineering course for a new professional masters degree program created by my department. Since I didn’t use slides or hand out lecture notes, some students were asking if maybe I could write up a summary of what I wanted them to learn in the course.…

High Desert Camping
My brother Eric does a great job in the cool uncle role, whereas I’ve been typecast as the nerdy dad — so my kids were super excited when he decided to join us on a spring break camping trip. As I usually do, I obsessively searched Google Earth for a perfect campsite and ended up…

Paths to External Engagement in Computer Science Research
The other day I wrote a post imploring academic computer scientists to at least occasionally break out of their research bubbles and engage with real engineering problems where their research matters. That post was, admittedly, a bit facile about how one might make this engagement happen. This piece suggests some ways. I don’t claim any…

Closing the Loop: The Importance of External Engagement in Computer Science Research
Computer scientists tend to work by separating the essence of a problem from its environment, solving it in an abstract form, and then figuring out how to make the abstract solution work in the real world. For example, there is an enormous body of work on solving searching and sorting problems and in general it…

The Basic Toolbox
This post is aimed at computer science students. In the software engineering course I’m teaching this spring, I often find myself saying things like “you need to know a scripting language” or “everyone should be able to run a code coverage tool.” Finally, the other day, a student stopped me and asked for the whole…

Strange Rocks 2018 Edition
My family, along with some friends, visited Kanab UT over Presidents’ Day weekend. One day we visited the White Pocket, a few miles south of the Utah/Arizona border. This area had been on my bucket list for a while now, but organizing a visit took time due to the long and punishing drive. An interesting…

Trust Boundaries in Software Systems
One of the big things that has changed in computer science education over the last 20 years is that it is now mandatory to prepare students for writing software that lives in a hostile environment. This content can’t be limited to a computer security course, it has to be spread throughout the curriculum. My experience,…

Stories Behind Papers: Integer Overflow
A couple months ago Jean Yang and Vijay Chidambaram had a Twitter discussion about the stories behind research efforts that you might hear over coffee, but that usually don’t get written up. Vijay started a series of posts containing these. I thought I’d write up a couple of them myself. Alas, none will be particularly…

A Conversation about Teaching Software Engineering
For better or worse, my impressions of software engineering as a field were shaped by a course I took as an undergrad that I thought was mostly not very interesting or useful. We spent a lot of time on waterfalls and stuff, while not covering testing in any detail. For the final project in the…

Some Goals for High-impact Verified Compiler Research
I believe that translation validation, a branch of formal methods, is just about ready for widespread use. Translation validation means proving that a particular execution of a compiler did the right thing, as opposed to proving once and for all that every execution of a compiler will do the right thing. These are very different.…
