Mobile device web apps

I used the advice on this Rails Cast to start converting one of my Rails apps to nicely support mobile devices. Working on my MacBook, I use the iPhone Simulator (since I don't own an iPhone) and my Droid phone to test on a real device.

So far most of the work has been deciding what I don't want to show when web requests come from a small screen device and tweaking the mobile device CSS file.

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...

Getting closer to AGI? Google's NoteBookLM and Replit's AI Coding Agent

Putting "closer to AGI?" in a blog title might border on being clickbait, but I will argue that it is not! I have mostly earned my living in the field of AI since 1982 and I argue that the existence of better AI driven products and the accelerating rate of progress in research, that we are raising the bar on what we consider AGI to be. I have had my mind blown twice in the last week: Today I took the PDF for my book "Practical Artificial Intelligence Programming With Clojure ( you can read it free online here ) and used it to create a notebook in Google's  NotebookLM  and asked for a generated 8 minute podcast. This experimental app created a podcast with two people discussing my book accurately and showing wonderful knowledge of technology. If you want to listen to the audio track that Google's NotebookLM created,  here is a link to the WAV audio file Last week I signed up for a one year plan on  Replit.com  after trying the web based IDE for Haskell and Python...

Topics: Recipe: Mark’s African Stew, and converting my Clojure CookingSpace web site to JavaScript

I wanted to convert my server side web site  CookingSpace.com  to mostly client side JavaScript. I used the Replit.com AI coding agent to do this, and while this is a subject for another blog article, I showed the Replit coding AI a snippet of my JSON recipes and nutrients file, and described in a few paragraphs the functionality of the new web site. I want to share a recipe that I created:  Mark’s African Stew Ingredients Optional: 3/4 to 1 pound of Lamb shoulder, deboned and cut into cubes, leaving some fat on the meat 2 tablespoons of any non-seed oil (Avocado Oil is good). (Avoid seed oils like Canola, Corn, Soybean, Sunflower, etc.) 1 brown onion, coarsely chopped 1 egg plant, partially skinned,  chopped into bite sized pieces, and heavily salt in a strainer. Before cooking, rinse well to remove excess salt! ground coriander (at least 1 teaspoon) Cumin  (at least 2/3 teaspoon) paprika (1 to 2 teaspoons, depending on how you like the taste of paprika) ginger...
