Nowadays I barely write code without an LLM, and my OSS productivity has gone through the roof. Look at what I've shipped on #Twig lately (more to come).
Steve Yegge's 8 levels of AI-assisted development described my last 2 years exactly.

But this isn't what I see at #Upsun: at the organization level, the challenges are different. So I tried to map a second scale, for AI engineering maturity in orgs: upsun.com/blog/8-stages-ai-e…

Most engineering teams already use AI. The real gap is whether the whole org is moving together. @fabpot maps 8 stages of AI maturity, from leadership silence to autonomous agents. See where your team stands 👉 upsun.com/blog/8-stages-ai-e…

As an OSS maintainer, my new rule is that anything a frontier model can find with some reasonable effort is a 0-day. Hence why I'm now shipping security releases on public holidays.

As an OSS maintainer, merging older maintained branches up can be challenging in case of conflicts. As agents are now good at following instructions and resolving conflicts, I've just created a SKILL for #symfony that automates most of the work (but keeping the human in the loop)

Deployed a new version of ai.symfony.com today - a bit more welcoming for starters to get into Symfony AI I hope :)

My favorite activity when coding: remove code
My new favorite activity with my coding agents: let them remove code they generated 😂
Also, I like removing cruft from AGENTS.md or SKILLS.md files
Writing code is also about removing code 😀
