 Hello Hello, this is a test. Can people hear us and is our audio balanced? Simo, can you say something? Yeah, sure. I'll say that the hack MD link should be provided in the in the mails that you receive Any other place where it was Richard? Oh, I think just the mail. So for this course registered people get the hack MD and Yeah, yeah, and different organizations have our own zoom rooms where we can like discuss stuff further. So if your organization has Provided such a zoom room or have organized such a zoom group them join join the other instructors there You can also talk there Yeah But the hack and these the main way we are we are going to have like discussion In this course. So that way everybody of us instructors not only us here in the stream Can answer any questions that you have and we already have a like a icebreaker in there. So if you feel like like Type something about how you Using scientific computing and what are you expectations and yeah, how do you start on Computing then it would be interested to hear what kind of people we have in the course. Yeah so here, I've just shared the hack MD and While you open it and you see It looks like a document You can scroll down and see where People are writing things if you go up to the top you can switch to edit mode and then Write stuff here and it appears here And this is really the way that we keep everything together in the course so Yeah, so as you notice we're in a live stream So you can't directly ask us questions, but in a course with a hundred people online No one's really gonna do that anyway Instead you can write your questions here at any time and we have multiple people Who are watching this and will be answering the questions live? also, whoever is teaching at the time will be watching the questions and And we can react directly there. We'll also share it during break times like this I'll also mention that sometimes The hack and the kind of get a bit slow if there's a lot of questions a lot of people editing at the same time So if you don't have it like if you don't feel like editing and you just want to watch the discussion there or Just focus on the stream Then you can leave it at the show mode and that will help everybody's life because it will like reduce the load on the hack I'm the inside. Yeah And if there's Yeah, correct. Yeah, and if this is anything like our previous courses, there'll be a lot of questions and comments there so If they don't get distracted by it There's also like if you if Richard you want to scroll a bit up. There's instructions or like hints like you might will notice that the screen is pretty weirdly like it's like this kind of like a Not not a landscape type of a screen Stream but but this top down stream There's a reason for it and reason for it is that it not everybody has access to multiple monitors And that's why we have this cream in this kind of a top-down perspective so that You can arrange your screens or different view Windows that you have in different places so that you can more easily like manage Things for these today's material. We are mostly told having going to have the screen going and then of course they have Can be questions But in the later days, we'll also run a lot of commands lots of stuff on the terminal No, or Separate kind of a like a access to today. It's busy cluster and and for that You probably have to manage multiple windows and it's easier to manage them by by locking them in certain places and and working with that So so if you want to organize your screen in a similar fashion as suggested there if you have like a full HD Laptop screen or something that might be a good idea Yeah Yeah, and let's see so Today we have multiple Well a lot of different sessions, it's sort of a starting day We you do learn about some important resources But overall it's a very like general starting point Yes, so so so basically today's topics are a bit more like Like introductory but at the same time you can learn a lot Like we are going to go through a lot of like interesting things that might help you along your way but we want to go like start softly and Like give you a custom get your custom to the system system that we have and I get you accustomed to do the world of Scientific computing because it's it's not only about Well, there's a lot of things you will learn today It's not only about like running programs if there's lots of things involved in it and We have a multiple different views that we are going to be Taking throughout the day at scientific computing from in like how it's organized to to what tools can you use? How do you work and personal views from? People who have gone through the whole ringer and and lots of time for questions that you can ask of us and of our talk People who are talking Yeah, let's see. We're starting to get some answers now. Yeah, like Simo, have you had formal training in programming or computer science? Yeah, some like I'm a physicist by background. So I've had some Training in HPC like our physics programs and it's it's busy coding in physics and and programming in computer science and But I would say still say that when I started actually using the systems when I actually started to do scientific computing No, no, well, it gives me a like a backbone or like a like this kind of a foundation to start build upon but it didn't Teach me like it taught me like 5% of the things so yeah, it it's it's you Unfortunately in this kind of it's a it's more of a craft than than a science sometimes that you learn by doing and and some of these things well, you you only learn by by Experiencing them yourself and we try to of course make it so that you don't have to like Experience them the hard way that we have probably gone through. Yeah Although, yeah, I had this metaphor like We learned well by doing it wrong many times Actually, this is what we'll be saying in the next talk, but yeah, like my theory is We learned well by doing things wrong many times So it's okay to like learn and struggle and so on But also like you tell a child You better be safe or you'll learn it the hard way Hopefully the hard way isn't getting a bunch of boiling water poured on you metaphorically Yes So Richard how did you start with computing? Actually, we'll talk about that Shortly, maybe we can okay. I'll answer that Um Well answer in a couple minutes or maybe one minute Yeah, like we we first first off like I we can go through a bit of the schedule like this topic Goes to the to our first talk quite soon Where we will be having an interesting talk between Richard and and Samantha One of the persons who have gone through this whole whole learning curve of competition competition, so from from beginning to Coming PhD, so there's a there's a whole View there and and this kind of a ringer that everybody goes to like this kind of a Crucible where you where you become Fluent in the computations. Yeah, it's it's it can be hard, but it can it doesn't have to be Painful and we of course try to make it Less painful for everybody and that's why we have these kind of a courses and we try to like get you accustomed to the lingo of the of the subject. Yeah
