The quality of new programming languages is apparent by looking at projects using the language

The community growing around the Clojure language is great. While the Clojure platform is still evolving (quickly!) browsing through available libraries, frameworks, and complete projects is amazing.

My "latest" favorite Clojure project is Noir that simply provides a composable mechanism for building web applications (using defpartial). I get to use Noir on two customer web app projects (and some work with HBase + Clojure) over the next month or two, and I am looking forward to that. The simpler of the two web apps is an admin console exposing some APIs on a private LAN and the Try Clojure web app is a great starting point, as well as an example of a nicely laid out Noir application.

Since Clojure is such a concise language I find it easy to read through, understand, evaluate, and use projects. Since I am still learning Clojure (I have just used Clojure for about 6 months of paid work over the last couple of years) the time spent reading a lot of available code to find useful stuff is very well spent because reading good code with an open repl is a great way to learn new idioms.

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,
