This year we're going upriver along the Dijle, from Leuven to Mechelen. The Lamot conference center offers a beautiful auditorium with view of the tower of St Rumbold, as well as lots of additional spaces for workshops, activities, or just to hang out and have a beer.

The part of the open source world that is strongly anti AI has done itself a disservice by shaming and dog piling maintainers. The result is that people are concealing their AI use. Instead we need responsible disclosure, people have to be able to disclose their AI use without fear of repercussions.

7 June

Would love to see a standard emerge like PROCESS.md or PROVENANCE.md where people can disclose if AI was used or not, and if so which model and tools, how they approach engineering, testing, validation, etc.

I don't see myself accepting AI PRs, for the simple reason that I do not have the will or bandwidth to adequately review them. Reviewing and subsequently adopting human code is already a significant amount of unpaid work, based on a tenuous social contract. Applying it to LLM code does not work.

When I merge code into my project that code is now mine. I have to test it, release it, maintain it. I have to deal with it forever after. I will be judged for it if it sucks. You may think you're donating nuggets of gold, but what I'm getting is puppies who may or may not have rabies.
