 The one thing is really great about this conference is the shepherding session. So there is this person, this is a professor in Spain. And she is also an airline programmer. So it just fits directly to it. So I share my slideshow of how I'm going to present. And she give me a more structured to my talk. So you can talk about these things. Let's take the slides. So I made some modifications. So yeah, thanks to Laura, whatever though, I able to have a much better presentation.
