Upgraded my live blog - you can now opt to have the most recent updates show up at the top of the page. I have pretty comprehensive notes from several sessions now, including the deep dive into the new Realtime API. https://simonwillison.net/2024/Oct/1/openai-devday-2024-live-blog/
This is what my edit interface looks like - I'm using the Django admin to add new "live update" rows attached to the entry.
