Polyglot programmers: setting up multi-language access to data

For those of us who tend to use several programming languages doing some up front work to make sure that we have access to all required data stores in the languages we use then makes it possible to really pick the best language for each task. I have a side project that I have been coding on for over ten years, with lots of code in Common Lisp, Scheme, Java and Ruby. If I can ever get a long enough break from my consulting business I have a few good ideas how to monetize some of this work. I was working on this project during a recent cross-country flight and I started adding a bit of new functionality in Ruby, switched to Common Lisp, and the implementation was a bit easier. I needed access to a PostgreSQL database (using PostgreSQL's built in text indexing and search) I use and once I had Internet access after the flight (for some quick reference), I worked out the few lines of code to interface with my annotated news data collection. Here is a small code snippet in case you need to do the same thing (using the lower level pg library instead of clsql because I only need to hit PostgreSQL):
(ql:quickload "pg")

(pg:with-pg-connection
  (conn "kbsportal_development" "postgres"
         :host "127.0.0.1" :password "password")
  (postgresql::pgresult-tuples
    (pg:pg-exec conn "select * from news")))

;; search support:
(pg:with-pg-connection
  (conn "kbsportal_development" "postgres"
        :host "127.0.0.1" :password "password")
  (postgresql::pgresult-tuples
    (pg:pg-exec conn "select * from news where to_tsvector(content) @@ to_tsquery('obama | congress')")))
I added this snippet to a directory full of snippets for common tasks for each language that I use.

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 w...

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...
