Heavy weight Javascript client applications vs. lighter weight AJAX

I experimented with Mjt last year: Mjt is a client side template system: Javascript is used to merge data from JSON web service calls with templates to generate HTML - all in the browser (except for data fetched from a server). Mjt looks solid and has been fairy widely used; an alternative client side framework is Sun's experimental (not for production use!) Lively Kernel project. If you have not played with Lively Kernal, give it at least a one minute try - it uses the Morphic GUI framework, so if you have used Squeak, it will seem familiar.

The big problem, as I see it, of client side Javascript frameworks is issues of maintainability. I have worked with Javascript heavy web applications that other people originally wrote and they are definitely much more difficult to jump into, understand, and modify compared for example to AJAX heavy Rails applications or GWT web applications.

That said, there is something tidy about the idea of writing web applications in two intertwined but separate tasks:
  • Writing JSON web services and separately unit testing them
  • Interactively developing the client side with a framework like Mjt
I like to recognize technologies as early as possible that I might use in the future. Although I don't (yet) feel really comfortable working with frameworks like Mjt my gut feeling is that this is the future because it makes it easier to work with multiple languages and platforms for implementing web services and makes it easier to mix up data from multiple sources.

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.

I am moving back to the Google platform, less excited by what Apple is offering

I have been been playing with the Apple Intelligence beta’s in iPadOS and macOS and while I like the direction Apple is heading I am getting more use from Google’s Gemini, both for general analysis of very large input contexts, as well as effective integration my content in Gmail, Google Calendar, and Google Docs. While I find the latest Pixel phone to be compelling, I will stick with Apple hardware since I don’t want to take the time to move my data and general workflow to a Pixel phone. The iPhone is the strongest lock-in that Apple has on me because of the time investment to change. The main reason I am feeling less interested in the Apple ecosystem and platform is that I believe that our present day work flows are intimately wrapped up with the effective use of LLMs, and it is crazy to limit oneself to just one or two vendors. I rely on running local models on Ollama, super fast APIs from Groq (I love Groq for running most of the better open weight models), and other APIs from Mist...

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 w...
