 record all of the talks and there's no chance that anything that learners can say or do that can appear in the stream. And this also means that we can immediately take and we can immediately release the videos online to everyone, which is something that's always been a problem with other courses we do. So I'm Richard Darst, I work for Altoscientific Computing and Enrico is here with me. Hello. Who also works for Altoscientific Computing. Yep. And we also have one of the benefits of this Twitch method is that we have other universities taking part. So we have a big group of people from the University of Oslo who are watching, who are watching the other own meeting. So we'll have some parts together and then we'll break up for different parts between the two universities in the first lesson. So we'll see how this goes. Yep. So as you may have noticed, we're sharing a vertical screen here instead of the traditional horizontal thing. So this is one of our theories. So normally when you see a screen share, it's the landscape mode. But whenever you need to follow along yourself with a web browser or something, that ends up taking up most of your screen, so you're not able to follow along. So we've arranged this so that you can put the stream or shared screen on half your screen and the other half is available for you to have your own web browser follow along to your work. Also we have one other thing. We have HackMD. Enrico, would you like to talk about how that works? Yeah, actually, if you want to show my window. Sure. You all got an email or at least most of you because somebody registered a few minutes ago. You should have received an email and in this email there's this HackMD. So the idea of HackMD is that it's like Google Docs, but you know, well, it's a little bit easier maybe to edit all at the same time. And what is useful is that you see now the window, you should see the same window if you have the link, and then you click on the pencil on top. And you know, you can just start editing it. So the top part I wrote it here, it's basically what Richard was explaining, this teaching material and this is how we could arrange your browser window and terminal window so that you can have all in the same room. But what is nice of HackMD that if you join, you can actually ask something here, you know, or for example, we could test it right now. Let's do a nice breaker. If you all visit this HackMD link, you can put your mouse into one of these spots and start typing, you know, what do you wish to learn today? And this is nice rather than using a chat because how can I say, the question stays for the future, we can take more time to answer some difficult questions, we can, you know, it's more asynchronous in this sense. So should we all test it? Should we all try to, what do I wish to learn today? That's what I wish to learn. I think this is one of the most interesting parts of doing it this way, because really, you don't need voice to ask a question. And in fact, using voice means that only one person can talk once, but here everyone can ask, can ask and answer questions at the same time. And we have some dedicated people that are watching the HackMD and will answer every question you may have. It's also nice because this, you know, let's say that somebody asked a question, here somebody wrote how to look cool like the hacker in the movies, and I can, and I can even write a comment, you see. Yep. So you can also interact with each other and when we can interact with you, you can have nested comments. They all kind of, you know, nest nicely. And then if there's too many people, if, let's say that the number of people right here at the same time, now there's 18, and that's manageable, you can always switch here with, if you click on the I, and then it's just like a rendering of what we are typing. So you can just watch, you know, if you don't have any question, and if you don't need to comment on anything. And Rico, can you say again how you edit HackMD? Yeah. So basically in this, now what I'm showing you is what you see when you open the link. The link, by the way, I didn't mention it's also at the bottom of this stream. In the very bottom, we have the course page, we have this HackMD chat. And so if you also can click there if you don't find it. And then you click the pencil here on top. And then you can start editing and kind of chatting in a synchronous way. Yeah. Okay. So if you have any questions, if you have HackMD, you can always ask. And if you're in some of the other chat things you can ask there, we should have people watching all of these and we can, well, keep it going. Yeah. So, um, yeah. Should we begin then? It's right at the time. Yeah. Oh, HackMD, you may have a lot of information overload here. So basically there will be um, two, well, there will be lots of people asking questions and lots of answers that it will stay here for the future. So you can always return to it later and follow up afterwards. So, um, should we begin? Yes.
