Thanks to Claude Code, it’s no longer a question of whether AI productivity gains exist for building software or not.

The questions are now more how do we structure job roles & companies given these gains and what will be the impact on tech workers?

This is what’s top of mind for me.

LibreOffice 26.2 is here: a faster, more polished office suite that you control - TDF Community Blog We’re pleased to announce the release of LibreOffice 26.2, the newest version of the free and open source office suite trusted by millions of users around the world.

This is where my opinion has landed as well. Most of the “typing” is done by LLMs for my own code these days, but I’m still in my IDE, reading, watching the diffs go by, interrupting to tell it to do something differently, refactoring regularly to make sure the code is legible.

v4.29 is out!

Eyes on AI Eyes on AI is a game that helps you understand how AI-powered surveillance impacts your life and community.

This is a fascinating tool! I just went through the exercise, and the personalized report at the end was really thought provoking. eyeson-ai.org

Block employee says the company dangled a 75% pay raise to get her to stay after layoffs — but she decided to quit "I saw my company discard half of my peers and double my pay," the former Block employee wrote. "That's not an honor. It feels shameful."

I have a friend who’s argued AI tools will let tech companies do more with fewer people, but pay them more as revenue per employee rises.

I was skeptical, but Block laying off 40% of its staff and giving the remaining employees a 75% raise has given me second thoughts.

A Guide to Which AI to Use in the Agentic Era It's not just chatbots anymore

Every few months, I write an updated, idiosyncratic guide on which AIs to use right now.

My new version has the most changes ever, since AI is no longer just about chatbots. To use AI you need to understand how to think about models, apps, and harnesses. open.substack.com/pub/oneusefu...

If you haven't yet changed how you teach and evaluate thanks to AI, you probably need to. This is not something that educators asked to happen, but it is worth noting what is out there - in this case an OpenClaw tool designed to cheat.

From an AI user perspective, the four big leaps so far in ability:
1. GPT-3.5 (ChatGPT, November 2022)
2. GPT-4 (Spring 2023)
3. Reasoners (starts with o1-preview, but the real deal was o3, Spring 2025)
4. Workable agentic systems (Harness + good reasoner models, December 2025)

🚀 We just shipped v0.226!
