 We're doing this with a mixed stream and a zoom so we have a stream on Twitch which is available to everyone because well why not make our knowledge free and then we have a private zoom for the people at who have registered so for private discussions on doing the actual exercises so you don't need to be in that zoom to take part in this course so you can just watch the stream and then probably learn something and do things by yourself you can even make your own private zoom meetings or whatever to work on exercises while watching us so as Enrico said Friday this is like watching tv together so we have the program you're following along and trying to learn something so we have something here a HackMD document um let me bring that up here so in this document to arrange ourselves some yeah there we go so if you're watching via our own link you see it down below and um where is it here we go you see it down below and the purpose of this is this is our chat so if you're using the zoom chat then you ask a question and either get an answer right away or not and it's too late but here you can ask questions like this here so you can type okay I'm typing yeah maybe you can see my pointer here yeah so here the pointer is not aligned with what you see on the screen that's interesting okay so you can write a question like this and then answer so this allows asynchronous and threaded discussions going on at the same time and then we take this whole thing and we'll publish it at the end so all of the questions and answers are available and this is really important this is one of the best ways to make um like to have this interaction interaction going on here um let's see so note you'll notice that we have a vertical aspect ratio in our window here so this is a very important thing also so you can have the stream vertically using half of your screen and the other half available for you either the hack and deed ask questions or your own windows to do your own um like your own problems and things like that like to work on the exercises yourself so take some time to arrange the windows right now yeah uh recommended layout is at the top of the hack empty where the you have a vertical window for the stream and then a terminal uh and a another browser window for the hack empty if you only have one uh one screen to use oh we should also say how the hack and deed works a little bit more uh i need to switch to my desktop so hack and deed has a several buttons up here there's view mode and edit mode so in view mode you see it like this and you see for example our recommended layout so web browser on one side you have your terminal you have browser with hack and deed or your own um like your own web browser there looking at our pages and then down below are the questions and answers to edit it you come up here and you choose edit and then you scroll to the bottom so hack and deed can easily become overwhelming with basically so many questions that you're following along and people are asking things all the time but that's okay so just let it be and you can always come back later and review things we also use hack and deed to send you links and stuff like that for example where we are what exercises to do at the bottom we'll have that information there okay so any other introductory info simo yeah maybe maybe i should introduce myself for the people who were here on friday well people anyways but so hi everybody my name is simo tuomisto i'm um i can't remember my title now but but basically i'm a i'm a guy who's working in alto ski comp maintaining the cluster and software stack on the cluster especially and i'm doing a lot of other stuff related to that yeah and i'm richard dars i work also work for alto scientific computing and my official title is staff scientist and well like simo i do almost anything that is needed okay so while we're getting started please open up the hack and deed and you see an icebreaker here please try to answer this question and you can tell us a little bit about yourself and why you're here yes it's like this course is it's very very general it's supposed to well be helpful for anybody in alto outside of alto the answers are pretty generic to all of the its busy clusters that are available and if you're just starting your work with scientific computing if you're a veteran there's hopefully some information for you anyways yeah so i guess it's noon should we get started yeah so let's see um i'm going to share my screen and show the course page here i have so many monitors open that it's hard to manage everything okay here we go
