 Okay, we are here today to present NuonCA. NuonCA is a development of the Fedora community, especially we did it together with the Fedora design team and the Fedora infrastructure team. Me is the part for the Fedora design team and I brought the colleague who actually did the work from the infrastructure team. So what is NuonCA? First some things before. How we see things is simple. What we need to do free software is simple contributors. And what we have to do is our users to convert them into contributors. Which means get them out for just using our software and do something. And so everything we do in Fedora is open so you can actually very easily contribute to our design. And one of the low hanging fruits we have in Fedora is simple the supplemental wallpaper. We have for each release we release normally each six months. We have a whole design for the release and we have a package with extra wallpapers. They are contributed from the community. I think each other distribution does that too. I know Yubuntu is doing that, Margea is doing that. I don't know, they are also from the Deben design team there in the audience. I don't know if Deben does it. They all do it. Zusevans to do it always but they never get it out. And it's a little bit problematic. Yubuntu is doing it with Flickr. Margea is doing it with Flickr. And we don't like to do it this way because we don't like to use somebody else's platform which makes us dependent. So we did all the time use our wiki to collect wallpapers. And that simply says that sucks because media wiki has not an upload limit. It has a limit to create thumbnails. And if you want to collect wallpaper you need a little thumbnail, e.g. that creates a whole mess. And then the second thing is we wanted to do it more open as we had it before. So as we had it in the wiki I collected the supplemental wallpaper and the design team did vote. And then we wanted to do it more open so we used our voting system from Fedora to actually make it possible that every Fedora company people can vote on the supplemental wallpaper. And that was done by hand from a colleague from Tosher. And that's an hard work if you have to add 120 possibilities for voting. That's not so nice to do in this voting system. And then I came up and said, guys we have to do something that happened last year in August at Flock. That's Fedora conference where the Fedora company people has come together. And we had a little smart head first and it was everybody quite yes to my idea. And two weeks later we had the first version running. And for Fedora 20 we actually could use Newang Sier for the vote. And now I give over to Pingu and he shows you Newang Sier a little bit. So the first thing I'm going to do is actually I'm going to move back from what Sierco just said. And simply show you how it looked before. So this is basically the wiki page where you add all the signals for all the image. And this is almost like the voting page was looking like. So you have the list of Fedora months. Each of them had a small info and you could click on it. And basically you would end up with the page which just shows you the picture. And eventually it was either directly the picture like this or you were going onto the wiki page. So this is when you have 120 links to click for every picture through a member and then order to get the 16 that you liked the most. It's a bit of a tedious task. So this is how it looked nowadays. It has its specific application. We have the front page where we actually display the winner from the last elections. Then you can see eventually if there is a link where you can vote and eventually if there are elections to which you can already contribute. So I'm going to walk you through. We first want to contribute your wallpapers. So there are a number of rules that you have to check. Of course you only allow some specific licenses, well open source licenses. There are minimum requirements from a technical point of view. So the picture has to be at least 1600 pixels wide and 1200 pixels high. But then once you've read through all of these you can basically contribute and upload your picture. You just provide the title. You can upload someone else's picture. So eventually you want to provide who is the original author of the artwork. Then if it's someone else then you actually want to link so that we actually know who is coming from. Then you can just upload your picture and select the license. Once this is done, the admin will just go through it. It will review the submissions. So here we have two submissions which I actually presented last year. You can see that the submitter is finger so that would be me. And you can see that the author is someone else. So in this case, the original author. And then the admin can just approve or deny you. Once this is done, then the submission period stops. And then the election opens. So this is what this table displays. There is one change which is going to open that's going to look like this one. The submission period which is open here, and the results are not published. Then you can have this one. The submission period is finished but then the vote is open. And finally the vote is finished so the results are published. And when you want to see how it looks for voting, so this is the interface that Ryan Lodge sitting on the back over there has designed. So instead of having a little list of links where you have to go through, you directly have the nice pictures. You can see them announced. Lightbox basically integration. So you see them a bit bigger and you have a better idea of how they will look on your screen. And you can just simply click on them. And one and two. And then once you've reached the limit, it directly says, well, this is the limit which you've reached. You can remove one. You can actually come back to the election. So you have 16 wall, you can choose up to 16 wall papers. So if you have no time, you can say, well, I just want 10 and then I have to go. So just press vote. And then thank you for voting. And then I can actually come back. And then instead of having to vote on 16 stills, since I already voted on some, then I only get the leftovers. So you can actually come back and vote in several time. But you can't change what you voted before. That's the only thing. And then once the time is over, then you actually get the results. So the results are simply a list of all the candidates and the number of votes which they add. So we are going to add the authors and the license for the artwork on this page as well. And there was a bit of a discussion in the design list on how many... So we want 16 wall papers, but do we want the user to vote on all 16s or do we want them to vote on 10 and then we still keep the top 16? So what we did is that for the elections, and I'm going to look at the real result, we actually did some statistics. So we have... Out of 16... You could have 16... Each person could vote on 16 wall papers. We have in total almost 1,553... Well, exactly 1,553 votes coming from 128 person. And this is the distribution. So we can see that out of 128 people, 67 voted on all 16 wall papers. So that's actually solved in our case the question. But as you can see, it's a much nicer interface. You can upload your artwork, the admin can review it to make sure it's valid, and then you can vote and nicely see the result from it. Yeah. And the best thing is it's free software, so other projects can use it too. And the part of what does for us the account system, federal account system, is just a plugin solution so other projects can use easily too and rewrite just a little bit and can have open votings like we have. Thank you very much.
