 Okay, next up we have George, who will be telling us about Debian for the elderly. Thank you. Thank you. So, we shall begin with the Latin Citation. O Tempora, or Boris. So, it is about Kikaro, who was born very, very long time ago. And he said that when he thought about young people who are insolent, who don't do things as they should. So, from this confidence, we have links to Wikipedia and other places where this idea is developed. However, in some countries, elderly people become numerals. Now, this is the stack of ages building somewhat pyramid in China. And you see that there are not so many elderly people, but you see this part. This part is going up and up. And in a few years, the situation in China will be the same as in Europe currently. So, when I began to design this conference, I did not know your age. So, I built it for an average attendee, but you are not average attendees. So, here are results governed by a website who made some inquest about the age of developers. And as it appears, the age pyramid of developers is much different from the age pyramid of general population. Of course, less people are young. So, I suppose that I am twice as aged as many people here. However, I act as a teacher in French public school, and I know many, many students which are younger than you. So, beware. I suppose you were insolent youngsters. Next generation will be worse. So, I am not yet retired. These are not my usual students. It is a computer social club, and these people accepted to make a little experiment with me to attend a few presentations about freedom in software and what that can imply. So, I already said that. I shall talk about the first computer I saw. When I saw my first computer, there was no computer. I just have big cards and punch holes in the cards, and after some time, maybe, the printer gave a result. That was in 1976. When you saw a computer for the first time, maybe you were very young, and maybe your parents were using it. And maybe they were playing. Maybe at that time, justics were news. At that time, phones were not that type of phone, that type. There are obvious differences. So, people born in the 50s have some difficulties to extract the telephone from their pockets. They often ask for very detailed explanation. When I began giving some courses for older people, they asked for many detailed explanations before becoming more fluent. At that time, people often have had a single job in their own life. Many people have been shorter in schools than you do now. I knew, personally knew, many diseases. Maybe you never knew them. And that's obvious. People who were born in the 50s now are more than 60 years old. Have you ever imagined you can reach such an age? Another striking point. Active elderly people are often women. Maybe because they live longer. Now, I shall talk about the little computer club, which accepted to make the short experiment with me. So, this club is named Les Libertés Numériques. And we met once a month from last March. I explained exactly what we should do. And it was about teaching new techniques in computer science with Debian. And explained how we can protect our privacy. And how far smartphone laptops are inviting our life. You can find some reports at this web address. So, invitations, etc. Maybe some of you already know this film, Nothing to Hide. So, the first meeting was about the film, Nothing to Hide. It's a young German artist who agrees with a group of hackers to allow a special application on his phone. And it is an ordinary spy application. It will just take data like geolocation and metadata about communication. And the attendants, they were 40 people, were most captivated by some testimonials. And those testimonials came from last World War II. And they made a comparison between the work made by the East German police, secret police, after the partition of Germany in two parts. And these spies had less information than Google, Facebook, Amazon, etc. can access now. As I announced during the presentation of the film, Nothing to Hide, the club was invited to install Firefox because it provides better tools to protect privacy. And some plugins, which you probably know, you block origin, Lightbeam, which can evidence the presence of spying programs. First demonstration was just to show how many spies are watching you when you go on the website of LaPost.fr, which is the French post. Here is it. Okay. Maybe some of you know, you block origin, which blocked. Oh, it was 57, a few seconds before. And now 61. I don't know why many other websites try to put some new data and interact with me. I only wanted to see my emails, but many people seem to be interested. I allowed JavaScript. Here is a comparison. The Deutsche Post, the German Post, apparently they knew bad experiences with the secret policy. So the secret policy, excuse me. So less data are given to spies. So what about other national posts? I never tried the Chinese Post or Taiwanese Post. So the question arises, is my computer spying me or is my telephone spying me? The discussion comes on the possible or impossible verification that what my software is doing. So it is important to use free LibreSoft1 because closed software cannot be audited. So I proposed, as I said, a USB stick for people who cannot easily install Debian on a computer, which can boot in a computer and provide a Debian distribution instantly. This one can be seen on a website, usb.freedeck.org. So as my club wanted, I used some of the... Oh, I have a strange phenomenon. Okay, the image is clean here. But the feedback I have is with many glitches. Okay, so you cannot recognize people. The images have been a little bit touched. So here are works about privacy using Firefox. Further meetings were about WebRTC and comparison with Skype. Many elderly people like to have communication with their sons, daughters, grandsons, granddaughters, etc. So when you have access to a high enough bandwidth, you can use Skype. So we made the demonstration about WebRTC. Unfortunately, the demonstration shows that it is still in beta state in this year. Things are improving quickly, but the attendees had a very interesting question about how can we trust that WebRTC is less invasive than Skype. So, yes, I already said that. Ah, yes, people appreciated a lot that WebRTC was able to work. Whatever the computer, whatever the phone, you are not tied to a particular type of computer. Here are explanations about how the negotiation is made before establishing a communication. So as a conclusion and just before questions. So Debian and the Canopyx variant which I presented seems to be well accepted by elderly people. Providing, they can be over, they can be helped to use it on their computer, which is equipped with Windows by default. And there are many protections around Windows to protect the system against the user. I had more questions coming from the members of the elderly club than I have usually from young students. And often the questions were wiser. If you watch the photos carefully, you probably saw that all people are using pencils and paper. How many people are using paper and pencil? One, two, three, four, five. I noticed also that elderly people are not so impressed by free bleeding edge computers. So when I present a computer which is five years or ten years old, oh, okay, very well. You are able to make it work. Oh, nice. How can I reuse my old computer? I got many, many interesting questions from attendees when they saw the film, Nothing to Hide. So the question of privacy is important and more important than I hear it from young people. And like everybody here, old people need to give some sense to their practice. And it is very explicit. I saw it very explicitly during the functioning of the club. And this club will work in the next month, too. Have you got any questions? Please? Oh, please talk. Oh, hello. So I got the opposite problem. In my cell phone, there's always big buttons. Wipe out my browsing history, clean off all my private data. If my finger just moves too close, it'll wipe out all my private data and everything. So I just hate that. And then I've been real old. I hate when my cell phone gets in one second to read some message and it disappears. I always can't read it fast enough. And I make the characters bigger and it pushes them outside the box. It don't fit in the box. And I use the Big Maps application. I make the maps bigger, but the road name gets smaller. So I'm always losing. And when I use the dictation, when you're talking to your cell phone and it types for you, it all uses these cool words like cause, like I said, because it says C-U-Z, thinking like I'm some kind of young person to make my letters to my mom look embarrassing. Yes. I suppose you are talking about the user interface. The user interface doesn't fit the general profile for elderly people. So I think there is a great work to be done. And that work can be done by volunteer people. I think I strongly believe that the Debian community can give a strong development to it. I really like the point you're making about the increase, the larger interest among elderly people in privacy. And I think you're tying it to the decades we've lived through and what we've seen before. World War II, these things are not that long ago. They're fairly recent that human beings were there who are still here now. Not too many, but we know we were raised with these concerns. And one place I see that come up so often is as a woman and as an older person, when someone asks me to do something on the cell phone, and I say, I do not like to use the cell phone for privacy reasons. They will send me to some, if I tell them I don't like something, they'll assume it's because I don't understand it. I don't know how to use Google and that's why I won't use Google. There's this assumption of not understanding it rather than understanding that, actually I think I understand some of these things better than you do. There's a problem here and I'd like to talk about it. And I think this comes up in the separating of the young people from the older people. The younger people are saying, the way you're doing it is really, really great and the reason the older people don't like it is because they're ignorant, rather than because there are some concerns there that are different, some different concerns. I agree, I agree. However, I teach very young people, I teach pre-graduate students, and I see that when we explain things, so when we have time to explain things, they accept that I am what is called in French, Nordinos, which translate to computer service, I suppose, and they see that my approach can be faster than theirs because I use a syntax. So I don't know whether I reply exactly to your question, but I don't reply to my students when they try to pull me in the new interfaces. I rather prefer showing them that they are missing something when they do not use old methods at some points. So you're showing them an alternative? That is possible for students who attend a course, which is known as Sciences de l'Information, that is computer science at a very light level, and they have two hours each week. For other students, the only interesting thing is to see that when they learn very basic things about Shell, for example, they are able to do amazing things which they couldn't do with graphic user interfaces. You know, you can do something with a knife, which is more acute than what you can do with a spoon. That's all the time we have for questions. Thank you, George, for your thoughtful talk.
