 all right test test one two three four oh I see my moderators here so possibly live well don't see me moving yet but I hope people can hear the audio so if you can hear the audio then say something in chat my moderator hears me that's that's a big plus is it good the audio or is it bad because I'm getting all kinds of errors from YouTube saying that the audio stream current bit rate is lower than the recommended stream bit rate greetings from Thailand greetings back to Thailand must be late there already time zones I can hear very well okay that's that's perfect everything going well let me test the music then since I have this stream deck thingy I can turn on my PC audio and I think the lag between stream and chat is pretty big yeah that could be I have the stream setting currently too low latency I can go to ultra low latency the big issue is is that if I click the button it will end the stream but if you say that then for tomorrow I will put it to ultra low so then when we have the lecture tomorrow that there's at least not a lot of latency but the nice thing is of course it's YouTube so it has this DVR mode so if you just press pause and come back in like 10 minutes then you should be able to continue where where you left off which is not possible on Twitch so at least that's what I enabled so let me quickly try a little bit of background music just to make sure that that's not too loud and that you guys can hear that so let me actually start it so if I continue talking it's too loud can people still hear me above the music because for me it's a little bit difficult let's see so far so good I think hearing music perfect all right so also networks so that's really nice for the for the breaks so when we have the animated gifts and stuff you have the breaks and that's that's fun to listen to some audio so it's really good all right two minutes ago guys I'm gonna mute myself listen to music all right you can hear me but also the music that's good it's the music not too loud because if it is I have to scale it back a little bit a little bit lower and take like five decibels off then is this better I have to keep talking of course otherwise you don't know the more violence the more annoying scale it back all right scale it back back back back back all the way back how about this I know it's a lot of violence so so it's actually minus 20 decibels that's a lot I wasn't planning on talking over the music it's just that I don't want to have people's eardrums like burst out because of the because of the audio difference cool so let's switch to me then I mean press a button and then we should go to the lecture scene so welcome can people see me that's probably yes I'm having a little bit of issues with the camera it's because the light come from this way I should have brought my influencer ring with me let me actually shut down the music it's really annoying in my ears because it's like really now all right it's pretty backgroundy okay so perfect all right so then we know that for me talking over it it should be like minus 20 decibels and I'm gonna write down that it's like minus 15 when we are then in minus 20 if I am talking all right good so yeah I had some I look pretty ah thank you thank you thank you you look pretty as well yeah so I had some issues with the camera because of the weird lighting situation here I think I will have to bring my influencer ring when it's really sunny outside today it's pretty okay because we just have a little bit of rain and it's relatively cloudy but seems to all be going well good so there's a couple of things that I wanted to test so one of the things that I wanted to test is my drawing board because as people might have noticed I do like drawing during lectures and especially drawing when I explain stuff right so I used to use the board in the background and I was doing it on twitch which meant that you had to switch the full screen and back to like the lecture layout but will we good yeah I can see actually that there's a big delay and well you guys are behind I'm in front of you guys so wanted to test the drawing board so let's see if we can draw so anyone has a suggestion what I should be drawing because that's of course the big question greetings from Uganda alright big big greetings back to Uganda thanks for joining the stream gondas should be the same time zone as Germany right so at least it's afternoon for you guys so a fish all right fish let's draw fish let's see so fishes are living in the sea so I'm first going to draw a little bit of water right so because you need a little bit of water so drawing time alright then a fish so what kind of a color fish do I want the last one that I did was green so I think that this one's going to be purple so just a basic fish let's let's do big purpley eyes on the fish right it's just two eyes and it's like something like this and then let's make it blue right so the eyes are really like popping out and we want to do a fishy so let's do a little bit of reddish as well inside of the fish so I'm not gonna do a we're one hour head 302 okay so welcome let me see so fishy fishy fishy so we need a fin on the back so that's something that we we start off with nice red fin so it's gonna be a pretty tropical fish because of all of the colors so goldfish are generally not that beautiful colored but let's do a little bit of orange as well so it kind of looks like a gold fish we need to have something like this and then we need to have another fin right because they're fish so they need fins alright good but it seems that the drawing board is working so that's what I'm happy about that's what I'm happy about so during the lectures we can just use the drawing board and so we need to have like this they did this is going to be a really really beautiful beautiful fish again it's always difficult at least normally I prepared them beforehand the drawings that I do so anyway anyway this seems to work so I would say it's a test successful it's not that I'm gonna draw a massive fish but just wanted to check if it works so is there anything else that a fish really has that we should take care of it's going to be a freakishly scary fish again yeah well I don't see many fish during my normal daily life right if you ask me to draw a mouse that's kind of okay I'm a mouse geneticist so I know about mice but fishies are a little bit difficult for me gills oh yeah yeah that's what I'm forgetting that's why it doesn't look like a real fish so let's give it like a couple of gills over here doesn't really improve the doesn't really improve but hello everyone hello Mary Machiao thank you for joining the livestream draw a fat mouse draw a fat mouse wait wait wait I can I can do that really easily let me draw a fat mind I'm not gonna draw a mouse anyway enough drawing I think like we can we can draw that's the that's the main thing right that's what I was worried about that the drawing board wouldn't work I've been dragging it with me for a couple of weeks in my bag now and I was worried that it would have been damaged or that the cables wouldn't work I tried drawing this morning but every time that I used the pen it started freaking out but seems to be okay now so that's good alright so drawing test completed successfully so we can use that so if anyone has questions during the lectures and stuff and I think that a drawing would be a good explanation then we can just do a little drawing it's definitely a fish yeah well you can see that it's a fish right like the water level makes the illusion complete right that without a water level it would just be like what the hell is this kind of animal with the red thingy on the on the top looks pretty good alright so next thing that I wanted to test is of course notepad so you should be seeing notepad I hope you guys are seeing it so let me actually start typing a little bit of code right so we are going to make my little script little script and then we are going to set my working directory to my D drive just because we can and I'm going to save it as test dot r I'm going to save it as test 3.r that's not bad plus plus yeah and code highlighting works is it visible is it not too small so if it's too small then code is readable okay yeah because I made it a little bit smaller compared to like on Twitch I can make it a little bit more small but I think that what I had it at was quite okay so let's do a little plot right so I need some data for that so let's take the volcano data set I don't know exactly what that's called it's data volcano or something let me take it so then we switch to r so let me see if that works no yes seems to work going to our don't know if there's a data volcano I think there's a volcano that's not what I was looking for that's not so let's search for it data's oh it's in data sets alright so we just have to load the library library data sets alright and then we do data volcano is it found like this this is the example good so that works alright so let's switch back to notepad so it's just library data sets and then it's directly active which is really nice and then filcano cano is what we can use and then we can do things like an image of it so without using the standard our example something like this should be good the only problem that I'm having is that when I'm searching to help it opens it up in the in my chat screen so I can't see the chat when I'm looking at the help for our which is a little bit of drawback so why does it find it here but not here doesn't really matter too much you guys can see the R window is the R window readable and when I do a plot can you guys is this is this all visible I think so right this should be readable if you guys can read the notepad plus plus window then this should be doable as well so I hope that that works out yeah the text is not that different in size might be a little bit smaller shouldn't go smaller it's all visible alright perfectly well alright then there's only one thing left to check and that's checking if I can show you guys some websites so let's go to hit up why not let's go to my hit up that seems to be okay although the text here is a little bit small what's a website that we generally use during the R course was the R help file thingies right so let me see if I can open up one of these and there it is pretty pretty good so that this is pretty pretty visible so that's a lot bigger actually than it probably should be but G network to yeah we can we can show G network to right just I don't know what's up with my typing yeah so that's pretty visible as well that's pretty visible as well very good very good seems to all work all right then there's so we had Firefox we had notepad we had R we had the drawing window we have the command oh no we didn't try the command window yet but that's visible I think I have to shut down the other ones and also the PowerPoint then is it all the way back there like it should be all the way on top here but it's just a command prompt so for when you want to install packages or something like that right like if you go to the D drive so you just say D double point CD D drive CD hit up and then we do our CMD install our CTL or something don't I have a nice example say they CTL mapping our CMD install our CTL let me see if that's visible that is pretty small I think very small yeah okay so let me edit the properties properties so go to like font size 20 these font size 24 then I think this is a lot better this makes the text right at least it seems to seems to be okay ish so it's just that it that it's black on black which of course is not the best thing to do but normally we would have like a notepad window on top of it right so you would only see like half of it so let me actually try that out so we would have something like this and then we would have the notepad on the background so we would type the commands in notepad and then copy paste them down to to this but this this seems to be okay ish you can control scroll yeah but then it doesn't tell me what the size is so it's just messing with the with the settings to make sure that that it remembers it for now for next time all right good good good so then there's only two more things to try and that's the animated gifs for the breaks so during the breaks I generally will not be here so I will do a I can just keep my microphone on so let me switch to the first break I think I like it like I made I took the old layout for the breaks and then make them a little bit newer so it pops a little bit more which is nice and the code is also correct now faiz Ahmed hello from Pakistan hello back to you Pakistan thanks for joining we're almost done with the test it's not a very long stream I was just wanting to make sure that everything is visible we might actually want to ban someone to see if that works just thinking about it because we haven't used the moderator tools on YouTube at all so who is willing to be banned from the channel for a short while so that we can check if that works in case we get any people that like throw things in chat which is not appropriate because I have no idea how banning people work okay so we can just hide the user I can make some a moderator I can report someone that's not what we want to do put user in timeout alright so let me see I'm just gonna put my moderator in timeout for like a little bit hold up I can use another account so I just timed out my you that's that's bad I am very sorry moderator there is no way to undo this alright I made a huge mistake I made a huge mistake 300 seconds is five minutes and it also deletes all of the messages oh that's that's horrible oh that's not as fine grained as I would have hoped alright so back to moderator status I'm sorry moderator I think I have too much power in this case and timeout for five minutes is also really really long I'm really sorry I hope that that will not be an issue that that will really not be an issue okay so let's try the other break seems to work as well again the same kind of layout that we had for the bioinformatics course I just added a little bit of flowers and made the title be coffee dot break equals true or coffee break true because it looks more programming so I think that all works so should be good we should be more in a setup for tomorrow then you're trying to circumvent your ban that's going to be an auto report to YouTube no welcome back welcome back it should I make this account of a moderator to I will make this make this account a moderator as well so interesting interesting but that was not really what I was expecting like there's no real fine grain being able to like remove a single message which I was hoping to be able to do in that sense that's a shame alright sounds very good sounds very good if anyone has any questions like if some like you guys are here right for an R programming lecture or something like that it's a test stream but if you have a question then we could do a little example program or something like that since I'm here anyway and I reserved an hour and it's now 20 minutes in so can do some more stuff and could listen to some more music let's add some music in the background just so that we it's really loud for myself so and this is probably also not going to work when I talk over it I shouldn't mess too much with audio shouldn't mess too much with audio that's everything that I wanted to test so most of the things work I can put people in timeout I can delete messages on Mars by just saying delete one message and that was not actually what I was expecting but I think it's a pretty successful test for for YouTube so let's just go back to the PowerPoint let me see if actually everything works if I start scrolling through it so I already did the lecture for tomorrow so it's relatively similar to last year's lecture it's a little bit different use the new layout pretty happy with the layout actually if anyone has any comments to the layout let me know the only thing that I really changed this time is use the yellow color which is showing up in my logo here use it also in the in the bullet points so I think it looks good it might be a little bit too yellowish but I'm a big fan of yellow so why not change a bunch of these figures and yeah I think we're all set for tomorrow so tomorrow we will have the course overview and introduction so that will be a relatively long lecture so the lecture will be around three hours I guess but that's because we don't really have that many assignments I'm also redoing the assignments so for the students that are following the course it's always good to do the assignments from last year it's also good to watch the lectures from last year then you know kind of what you can expect there won't be massive changes in the lectures the only real thing which will change of course is the lectures that you guys provide me with right because it's for you guys to learn I already had a little video up asking for some comments and suggestions let me actually look at that because some people wanted to have string manipulation with our so doing kind of text editing or pet changing parts of text I think that's a good idea that's not in the current lecture series but I think we can do something like that so text analysis in R and then the other one was multiple regression and econometry I'm not that good in econometry but we can add a little bit of econometry in there because I think that like the course is for you guys so if you have any suggestions and say well we really really want to do that then we can just do that so and I'm here to make you guys happy right like I already know how to program and it's you guys that are following the course that want to learn how to program in R so of course the basics we will explain so the first five six seven eight lectures will be very standard very similar to the lectures that we did in 2021 but if you have very specific requests or think like no I really really really want to do X with R and it can be anything that you want right let me see because I actually wanted to check that as well so I'm trying to install the emoji library R because emoji is it's always fun to do stuff with emojis it's really not found no because I need to have a string so I need to put quotes around it alright so because I actually like R because you can actually do some fun stuff with it so I have to look for the code but I made it for a colleague of mine so it should be in colleagues and then I made this for Dica so I'm wondering if this will work actually on stream so because you can use R to make could not find function emoji yeah I want to have library emoji font alright install packages that's not gonna work and it'll start installing a whole bunch of packages as well and then like I like doing a kind of animations with R so things like this so I hope that that actually comes out pretty well on stream so it's something that I made just to show how easy it is to do like little animated GIF kind of style things with R so if you guys want to learn how to do something like this so that you can impress your friends and colleagues by having a cow move and rotate across the screen in your R window then we can definitely add like a little something like that but that seems to work as well so I think that's kind of it so thank you guys for joining thank you guys for all of the feedback my moderator is back good so you you learned your lesson in timeout I hope it's good that I didn't ban you because I didn't see any like unban command so probably when I ban you it's forever and ever that would be fun yeah that would be fun right to learn something like like that like I like doing stuff like that a lot it's just that it takes like a lot of tinkering to make it work really well but in the end it's just making a whole bunch of plots right as soon as you make like 24 plots per second it looks like it's moving so you can have restarted by just copy pasting in the code so and the cow comes in and then like the banana peel falls on his head and he like flips around and all of this is like little pieces of code and then the little ghost emoji comes out we can we can do more we can do a lot more you can you can go really crazy with the emoji library good let's switch to my finish screen then so the finish screen is there so that when I am intending to end the stream that it automatically mutes my microphone and all of the headsets and stuff so I just wanted to check if this works so for now thank you guys so much for being here it's just a little 30-minute test stream if you have any suggestions on some topics that you want to learn definitely definitely let me know and for now I will say goodbye and I will see you guys tomorrow at 2 so enjoy the rest of your day and thank you for being here
