I like computers. I try to make them like me back. More than computers I like humans.
It's not always sunny here in the South of Spain, but being able to workout outdoors at the seaside in shorts and a T-shirt in November makes it all worth it. Happines++

This weekend we made a 2 days trip to Ronda which has now become my favorite non-coastal town. Mind-blowing views. Thank you, 🇪🇸 Spain!

How to get an "unfair" advantage vs AI? Build real human connections.
I've tracked that the a podcast episode takes me 8-10 hours to produce. Why do I do it? Well, learnings. But the most important is the motivation it gives me!
Interacting with someone who I admire === energy++

Today I did a talk on MCP in front on 30+ devs.
I love writing and hate speaking. So much energy goes into how you speak instead of what you say. When writing, you can edit and refine. When speaking, it’s all real-time.
But being good at speaking will always gives you a huge edge!

Very few things give me better vibes than receiving reviews like this one from readers of my LangGraph js book: jscraft.gumroad.com/l/zbbgz

More and more, I see files on GitHub that mix human language and code. I'm starting to wonder if Andrej Karpathy might be right when he says that the most popular programming language will soon be English.

TIL: If you replace "https://github.com/repo-url-here" with "https://gitingest.com/repo-url-here", you can instantly turn any GitHub repository into a text digest of the codebase, perfect for feeding into an LLM.

The 6 hour podcast with DHH and Lex Fridman was too long for me to sit through, but it's full of great ideas on AI, learning, and programming. I didn’t want to miss out, so I took the YouTube transcript, passed it through an LLM, and ended up with this nice 170-page book for the weekend.

Super excited to share my interview with @humanwhocodes.com !

After all of these years, Sublime Text is still my favorite writing environment! It is not my code editor anymore, but it is my favorite note-taking place and text editor. 🤓

This is one of the best one-liners I've read recently:
July 10, 2025 at 5:34 PM
I use www.trueup.io/job-trend to monitor the tech jobs market. The tech job market is slowly & surely continuing to grow at a natural pace. I don't think AI will take over our jobs! As long as you are competent in what you do, AI will make high-tech jobs even more important!
