My large Haskell + Python project KGcreator (tool for automating the generation of Knowledge Graphs) and auto code formatting

You might wonder what the topics of my large Haskell + Python project KGcreator and auto code formatting have to do with each other.

I addition to working on two Python books (Python Intelligent Systems and Deep Learning and Graph Databases), my main 'retirement' activity has been write a lot of Haskell code and a smaller amount of Python code for my KGcreator project. After reading a discussion on Hacker News yesterday about Python code tidy/auto-format tools, I decided to add Makefile targets.


After a 'stack install stylish-haskell hindent' and a 'pip install yapf', I added something like this to my Haskell top level Makefile:

tidy:
  cd src/fileutils; stylish-haskell -i *.hs; hindent *.hs
  cd src/nlp; stylish-haskell -i *.hs; hindent *.hs
  cd src/sw; stylish-haskell -i *.hs; hindent *.hs
  cd src/webclients; stylish-haskell -i *.hs; hindent *.hs
  cd test; stylish-haskell -i *.hs; hindent *.hs

And something like this to my Python top level Makefile:
tidy:
  cd botorch_bayesian_optimization; yapf *.py --style='{indent_width: 2}' -i
  cd coref_anaphora_resolution_web_service; yapf *.py --style='{indent_width: 2}' -i
  cd data_fusion; yapf *.py --style='{indent_width: 2}' -i
  cd deep_learning_keras; yapf *.py --style='{indent_width: 2}' -i
  cd deep_learning_pytorch; yapf *.py --style='{indent_width: 2}' -i
  cd discrete_optimization; yapf *.py --style='{indent_width: 2}' -i
  ....
Trivial stuff, but I already find my KGcreator and my books' codebases easier to work with. For Common Lisp and Scheme I always just rely on using the tab character to auto-indent and leave it at that. I use VSCode for both Haskell and Python development and after experimenting with a few extensions I decided it was easier to add a make target. Nothing is automated right now, I 'make tidy', 'make tests', and then 'git commit...' manually. Still to be done is adding git commit hooks. Fortunately I can use notes in one of my old blog posts as a guide :-)

Ruby Sinatra web apps with background work threads

In Java-land, I have often used the pattern of writing a servlet with an init() method that starts up one or more background work threads. Then while my web application is handling HTTP requests the background threads can be doing work like fetching RSS feeds for display in the web app, perform periodic maintenance like flushing old data from a database, etc. This is a simple pattern that is robust and easy to implement with a few extra lines of Java code and an extra servlet definition in a web.xml file. In Ruby-land this pattern is even simpler to implement: require 'rubygems' require 'sinatra' $sum = 0 Thread.new do # trivial example work thread while true do sleep 0.12 $sum += 1 end end get '/' do "Testing background work thread: sum is #{$sum}" end While the main thread is waiting for HTTP requests the background thread can do any other work. This works fine with Ruby 1.8.7 or any 1.9.*, but I would run this in JRuby for a lon

My Dad's work with Robert Oppenheimer and Edward Teller

Robert Oppenheimer and Edward Teller facilitated my Dad getting a professorship at UC Berkeley when I was 3 years old. Oppenheimer left Berkeley but Teller was a good friend of my father and I remember him being in our home. Three weeks ago, my wife and I were just leaving to see the new Oppenheimer movie when my Dad called. He mentioned that when I was in grade school he was invited to give a talk at Princeton. After his talk Oppenheimer talked with my Dad and invited him to have dinner at his house. My Dad said Oppenheimer was not well (I think he died of throat cancer soon afterwards) but his wife Kitty carried the conversation. My Dad, Ken Watson, passed away 10 days ago on August 18, 2023.

Time and Attention Fragmentation in Our Digital Lives

  As humans we have evolved over a few million years to be both attentive and reactive to danger, live in social communities, and spend much of our time being in the present moment gathering and eating food and socializing. The behavior of rapidly changing short attention to content on social media, too many good short form things to watch on streaming video entertainment platforms, are all rewiring our brains in an unnatural and unhealthy way. I fight back, but in really simple ways that entail little ceremony: Almost every morning I spend 30 minutes scanning Hacker News (about 10 minutes), Apple News (about 5 minutes), and the remaining time on Twitter and Mastodon finding interesting new (mostly tech) things. I make notes in a temporary Apple Note: links of things I may want to research, try, or simply read that day. I like to get this all done at once, and then not feel like I need to interrupt my activities during the day to “catch up” on what is happening in the world. In a way,
