I can confidently say I’ve learned at least one significant new concept every day over the past two to three weeks. It is not only satisfying but also quite stimulating. This will keep me from aging, that’s for sure.

An Important Lesson

When I started my studies in computer science over 40 years ago, we learned to read functional specifications and then translate them into machine instructions (COBOL, FORTRAN, Pascal, etc.). It was the training of a programmer. I knew that one day I could become the person who writes functional specifications. I didn’t become a programmer, nor did I work in the development world.

Due to my recent experience with Claude AI, Claude Code, and Vercel to create custom applications, I realize that I have become the one who writes functional specifications, but for processing by artificial intelligence. What does this tell me about the profession of a software developer? The need to write specifications remains essential, if not more so, even with powerful tools like AI. I think it’s a valuable lesson.

On OpenRouter.ai

I just finished reading about the service openrouter.ai. I was curious to understand the purpose of this service as well as its business model. I saw several instances of this service being used in n8n workflows. The problem I see with this service is that it makes the consistency of the quality of responses from the requested LLMs even more unpredictable. Each request could be handled by LLMs with different characteristics and performance from one time to another. I’ll pass on this, but I still learned something tonight.

Another update to my blog: the blog post categories are no longer listed on the main page header. Categories are shown on each blog post. I think that’s enough. Categories are available in the Archive page. This makes the home page less busy.

Today, I created a new blog post category. Now, all blog posts related to automation (usually n8n-based) or AI will be assigned the “Automation & AI” category. I went back to my blog posts and updated a few of them to reflect this change. You can follow the blog posts with this dedicated RSS feed, which is automagically created and maintained by Micro.blog.

I am currently testing the Ubiquiti Travel Router in a café near my home. The setup operation is simple, and I have full access to my home wifi network, which is one of the goals of this purchase. The only small drawback for now is the slow startup of the device.

I’m discovering this powerful n8n node this morning. This means I could trigger that workflow from an external source, such as a Telegram message, and receive a response with some RSS content.
