The world is just moving too fast. I just took a deepish dive into Typesafe.AI's Jev, and Firecrawl's Alexandria today, and it's made me think I should just rip up and start again on some of the Mastra workflows I've been working on for the last couple of months. Hey ho.

I've been using zed.dev almost exclusively as my main IDE for most of this year, with a brief diversion to Cursor. It's really good as a traditional IDE, but the agent harness is very nice to use too. The main thing I'm missing now are good database tools.

I've changed from using Cursor to Zed for agentic coding. Using the Zed built in agent harness which displays all the "thinking" output from the LLM. One interesting observation is how often the LLM has repeating thoughts: "I'm noticing ..." over and over.

Currently experimenting with creating an AI generated corpus of business information. We're starting from a large curated list of business "challenges". We will then index it and use it as input into an agentic chatbot. The hunch is that this will provide more value than a straight chat-with-GPT.

Crazy having a national-news-story trail derailment just a short distance from my house. I walk up and down the riverside footpath next to where the train came off the track, between Lewes and Offham, all the time. I guess I won't be going to London any time soon!

There is a huge amount of "cope" among arts people who claim they can spot AI prose (for example) and that it's sub-standard, but then pay $2m for a crime novel that later turns out to be AI generated. I'm tempted to ask if it really matters if a book is AI generated so long as you enjoy it?

Amazing how many of my late 50s / early 60s friends rail against being called middle-aged and insist that they are still young, as if by sheer force of will they can magic away their greying hair and wrinkling skin.

This is a good read. I do think people misunderstand what humans are actually designed for - we're highly optimized survival machines. Survival and reproduction in the physical world is not the same as being good at maths or coding, which are probably by-products. www.noahpinion.blog/p/what-will-...

Today to Charleston in Lewes for the Walter Sickert and Gladys Hynes exhibitions. Dimly aware of Sickert before, but I'd never heard of Hynes. Her exhibition turned out to be the most interesting, especially on the interwar art world that she was a part of.

We need a word for non-AI computing. You know, the old thing with deterministic programs. I wonder how long it will be before most people can't discern the boundary between AI and non-AI computing?

My current project is hooking up an agent (based on mastra.ai) to a Strapi CMS using a RAG and the Strapi MCP. Mastra is very easy to work with and we've been able to hook the whole thing up in just a matter of days. With lots of help from Claude of course.

What's the word for non-AI computing? I can imagine that it'll be a thing soon where people say their computer system does not have any AI integration. I wonder how long before the average person can no longer discriminate, or even understand that you can use a computer without AI?

Currently working on adding pentatonic scales to Guitar Dashboard. It's a tricky one because of the huge range of chords that work with them. My current approach is to find all diatonic modes that are the superset of the pentatonic and display the chords of those modes as concentric rings.
