EV3 webcams; Lisp and Smalltalk

It's always interesting to read about ways in which one's work has had an impact on others.  Here are a couple of recent examples that I am happy to have the opportunity to reference:

First, I'd like to thank Andy Shaw and the leJOS team for their support of my webcam work on the EV3.  They were able to incorporate my work into the leJOS code base, for the benefit of anyone wishing to use the leJOS platform for computer vision on the EV3.  It was great fun getting it working this past summer.  It would not have been possible without the terrific infrastructure their team has put into place, as well as their hands-on assistance as my project proceeded in fits and starts.

This semester, I am teaching a course focusing on the use of computer vision as a key sensor in robot programming.  In the process, I'm experimenting with different vision algorithms on the EV3 platform.  After the end of the semester, I plan to post in some detail about what worked best for us.

Second, Malcolm McCrimmon, who several years ago was one of my students, has written a fascinating reflection about what makes both Lisp and Smalltalk such powerful languages.  I'm a bit humbled to see that this reflection was prompted by an impromptu four-word answer I gave to one of his questions in class.  I'm teaching the course again this semester, and I'm looking forward to incorporating some of his insights into our classroom examination of these languages.
