The work itself — Ghostty now, Terraform and Vagrant before it. For this person the commit history is arguably the primary publication.

The best terminal multiplexer is the one nobody has to learn; needing to be learned at all is the first design failure.
I can't tell you the number of people over my career that have said "I tried learning tmux" First problem: the fact you have to "learn it" at all. The world's best multiplexer is the one you don't have to learn. It just works.

A low-effort AI-designed landing page costs a product its audience before the product itself is ever judged.
I'm so incredibly tired of seeing low-effort AI-designed web pages. I basically bounce off any new product immediately when I see it (never get a chance to judge the product itself). Lots of thin lines, glowy styles, inconsistent fonts, lots of monospace.

Chatbot interfaces are the wrong tool for meaningful coding work, because you are mostly hoping the model recalls the right answer and correcting it requires a human in the loop.
Immediately cease trying to perform meaningful work via a chatbot (e.g. ChatGPT, Gemini on the web, etc.). Chatbots have real value and are a daily part of my AI workflow, but their utility in coding is highly limited because you're mostly hoping they come up with the right results based on their prior training, and correcting them involves a human (you) to tell them they're wrong repeatedly.
My AI Adoption Journey Said 5 Feb 2026
Effective use of AI coding tools requires domain expertise: the tool should be used as an assistant, not as a replacement for the engineer.
This is intentional and I believe good AI drivers are experts in their domains and utilize AI as an assistant, not a replacement.
