I have, for many semesters, run a reading group on Category Theory. Towards that end, I have a lot of notes on topics in Category Theory. Git repo of TeX documents available locally.
In January of 2012, I taught an introduction to Haskell to 32 JHU undergrads. This material is by now very dated, but perhaps informative all the same. See Fun with Haskell, Intersession 2012.
Various Student Seminar Talks¶
In 2011, I gave a (not very well done) talk about artificial life to the JHU ACM. Slides are available in DVI
I have some work towards an “automaton zoo”, with a similar aim to the “complexity class zoo” here.
I was involved in the bring-up of a modern computing stack for the JHU student chapter of the ACM, involving ZFS, ceph, Kerberos, OpenLDAP, OpenAFS, and OpenStack. A huge amount of effort was spent writing documentation for subsequent generations. Unfortunately, all good things must come to an end and so perhaps all that is left of this effort is my local mirror at https://hydra-www.ietfng.org/jhuacm-notes/ . Originally, and if ever those “subsequent generations” bring things back, it might again be found at at https://www.acm.jhu.edu/~admins.pub/systems/ .
While at the JHU ACM, I was also the curator of its computer history museum; some documentation existed at https://www.acm.jhu.edu/~acm-museum/ but this, too, seems to have disappeared. I am sure I have a local copy if anyone is interested.
I have contributed a few pages to the OpenAFS wiki:
