At work, nearly all of my code is written by AI. I still believe the practice of Software Engineering is as important as ever, perhaps even more so. Also, scope increases when using AI tools. I find myself simultaneously building my systems and building AI tooling that builds my systems.

AI tools I've been using the most, both at work and personally: 1. agent-shell - As an Emacs user, really like having all the Emacs commands available while interacting with Agents. Easy to extend. 2. Claude Code 3. Opencode - Using this more and more, especially with other models.

Finally wrapped up Advent of Code 2025 over the weekend. Practically all my code at work is AI generated nowadays, so it was nice to get some hands on coding in for a change. I did use AI for the not so fun parts: scaffolding files and documentation.

For emacs claude code integration, currently using github.com/stevemolitor... and have been very pleased. Also want to try github.com/xenodium/age... at some point.

So far, the AI coding assistants I've tried in earnest are GitHub Copilot, Cursor, and Aider. I think Cursor is the best in terms of usability. But I'm rooting for Aider because: 1. It's terminal-based and not tied to an editor. 2. It's open source. aider.chat

aider is AI pair programming in your terminal

Just finished listening to The Pragmatic Engineer's podcast episode with Grady Booch - highly recommended! Hearing him talk about the history of software and his enthusiasm about the future of the industry lifted my spirits. It's great to see such passion from industry pioneers!

Java 21 introduced Virtual Threads. Do these make batch APIs obsolete in terms of maximizing throughput?

At AWS, I worked on projects using various languages: mostly Java, but also Typescript, Python, and Ruby. Small, autonomous teams meant leads "chose the right language" for each problem.

I love using LLMs, but I wasted time this weekend attempting to use AI to create an AWS Lambda function with Puppeteer. The models I tried, gpt-4o and Amazon Q, generated projects that failed at runtime. Even worse, they suggested solutions that threw me off course.
