 Okay. Good morning, everyone. Hi. Welcome to the second edition of the HPC Big Data and Data Science Dev Room here at FOSDEM. We are very happy to do this again after a very successful event last year. So this Dev Room is organized by four people. So Kenneth here, Ewan back in the video. I'm Roman on the other corner and myself. I'm Vasya. So please read out to us if you need anything like organizational or administrative or if you're a speaker and you haven't tried if your laptop is working. Okay. So this year we had, again, a lot of submissions. I think 42 or 43, maybe a few late ones. And we tried our best to accept as many as possible. That's why all the talks are short. So we have 15 full talks, 20-minute talks and five lightning talks in the middle. So as you will see, these year's trends evolve a lot around containers, machine learning and streaming and stream processing. So we've tried to somehow group the topics together. So in the beginning it's more, let's say, related to HPC topics and then gradually moving towards big data topics through data science, somehow like that. So I hope you all enjoy. You have an exciting day. I only have two requests for you. One is if there is an empty seat next to you and you can squeeze so that more people can sit, please do. And the second is please use the feedback forums on the website. So if you go to the schedule and you click on its talk, then underneath you will find a link where you can give feedback. So if you liked the talk or you didn't like the talk or if there's any comment you want to leave for us for next year or anything from great job guys to, I don't know, this didn't work at all. Please let us know so we can improve. Okay, so any questions? Okay, thank you. Enjoy the day.
