My wife Carol and I have been practicing social distancing and wearing masks for shopping for over 5 months now. Welcome to the new normal and a crazy world in which entertaining and seeing friends is done by meeting in people's yards and everyone bringing their own "meal in a bag."
I enjoy writing so I have been updating my recent books, starting with Loving Common Lisp, or the Savvy Programmer's Secret Weapon and A Lisp Programmer Living in Python-Land: The Hy Programming Language. These are free to read online and licensed with Creative Commons Share and Share Alike, No Commercial Reuse, so you can also find copies on the web (hopefully up to date copies!).
Last month I started a much larger project: I have not updated my book Practical Artificial Intelligence Programming With Java since the fourth edition was published in 2013. I have discarded a lot of older material like exert systems, and have three new chapters on the semantic web and also a new chapter on deep learning. I also copied the material on anomaly detection from my Power Java book that is now discontinued and updated that material. Lastly, I am revisiting how readers install, run, and experiment with the code examples. I am still using maven but I am being more consistent, all of the examples are also installable libraries, and now some of the examples use the libraries developed in other examples.
For fun, I have been buying more material for my Oculus Quest VR device. Favorites include ping pong, racket ball, the Star Wars Darth Vader Immortal 3 volume set, and I enjoy a lot of 3D art that people post.
For exercise I try to hike every morning from 5:30am to about 6:30am (I live in the mountains of Central Arizona and even at high altitude it gets warmer later in the day). My wife and I cancelled our gym memberships so I bought myself some weights that I keep in my home office. I am a huge fan of the Apple Watch and I use it to track health and fitness activities.
I hope that you, dear reader, are doing well in these crazy times we are living in.

Here are some of my of my recent notes that might save you some time, or teach you a new trick. I have had good results using the py4cl library if I wrap API calls to TensorFlow or spaCy in a short Python library that calls Python libraries and returns results in simple types like strings and dictionaries. I just committed a complete example (Python library and Common Lisp client code) to the public repo for my book Loving Common Lisp, or the Savvy Programmer's Secret Weapon that will be added to the next edition of my book. Here is a link to the subdirectory with this new example in my repo: https://github.com/mark-watson/loving-common-lisp/tree/master/src/spacy I frequently make standalone executable programs using SBCL and I just noticed a great tip from Zach Beane for compressing the size of standalone executables. Start with rebuilding SBCL from source to add the compression option; get the source code and: ./make.sh --with-sb-thread --with-sb-core-compression sh in
I retired this spring after working on artificial intelligence projects since the 1980s. Freedom from having to work on large projects for other people and companies is liberating and frees up time for thinking about new ideas. Currently I am most interested in deep learning models for generating and evaluating recipes - for now I am using a GAN model (which I am calling RecipeGAN). When I managed a deep learning team at Capital One, I used GANs to synthesize data. During a Saturday morning quiet-time hacking sprint the first month at my new job, I had the idea to take an example program SimpleGAN that generated MINST digits and instead generate numeric spreadsheet data (using the Wisconsin Cancer Data Set that I had previously used in my books as example machine learning data). I was really surprised how well this worked: I could generate fake Wisconsin cancer data, train a classification model on the fake data, and get classification prediction accuracy on real data samples that wa
