"ClojureScript: Up and Running" book

I bought the Kindle edition of the book "ClojureScript: Up and Running" by Stuart Sierra and Luke VanderHart a few days ago. It is well written and a good way to ramp up on using ClojureScript for web client programming in Clojure instead of Javascript.

I have experimented with ClojureScript before, and now that two of the three Coursera classes I have been taking this fall are done, getting up to speed on ClojureScript has moved to the top of my side-project to-do list. (BTW, as I have written before, one of the classes I have taken this fall is the Functional Programming Principles in Scala, and that class is also of value to Clojure programmers who might not have a strong interest in Scala specifically, but have an interest into better understanding functional programming - the lectures for that class were especially enjoyable and useful.)

I have converted all three of my main web sites to Clojure + Noir in the last few months and this is a great combination (especially when used with a high level UI framework like Twitter Bootstrap or Dojo Mobile) for web applications. Since I am already happy with this web app development stack, why learn ClojureScript? Basically because I don't like to do a lot of coding in JavaScript. In the last few years I have enjoyed several projects done using either GWT or SmartGWT where both web client side and server side is done in Java, and I anticipate using ClojureScript, but only for projects with complex client side functionality.

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,
