 So good morning everyone another day here of depth conf in Taiwan It's great to see you here in the morning and people are still streaming in into the venue and we are Having here the first talk of the day in the room sheshawn which with George Kazna da but there are different ways to pronounce the name for example It's a Turkish name so it could be Hasna da but like if you speak it in French where you are living in France, right? Then you could also say Kazna da, but you can also we can also call you just a George. Yes, okay This is great. So thanks for being here and you're having two sessions So one session today and one session tomorrow is a workshop tomorrow And people can attempt the workshop even if I did not attend the conference today. Yeah, so So yeah, it's great to have you especially because you have been working over many years already with People in Asia for example in India and Praveen Kumar and others So and we're really looking forward here and with more details from your talk So a round of applause for George. Thank you so the title of the conference is pocket debian in my school and so I just take pocket debian and I shall be talking and Rebooting my computer in real time. So This will be just a minute I developed a debian pocket because there were issues with Using debian on computers in my school All the teacher did not want to have a foreign system They just prefer Windows OS and the rooms are used by every teacher and So there is some mainstream and I struggle against that mainstream culture But with the students it is way easier Because every machine has been configured in my school to boot like mine That is it will recognize immediately when USB stick has been switched on and boot on the USB stick So just a minute my students are generally Surprised to see how fast The boot can be so I have the complete boot Screen here I make just a little adjustment In order to have the same image on my computer and on the common screen so Screens This one should be I start my talk again So this one So here it is I am teacher in Dunkirk, which is the Northest part of France and in lycée Jean Bar. I belong to a few Organization and association a full April which are free software organization in France Offset which used to be an international free software association and I am Debian developer for a few years So teacher side when you use computers in French schools How can we know that something is useful just break it and what it is broken You see immediately whether it was useful or not As I am in charge of the school network My colleagues asked me whenever something breaks. So here are the question in Order of decreasing importance The first thing they must do is to take the attendance. So if that doesn't work They are lost Then I cannot access internet The computer is way too slow No, but that's window. I explained them But they cannot hear it. I Cannot print PDF files. Oh, that's quite a new feature of our school computers the printers are windows based and I Don't know why the drivers are not correctly configured. I cannot read my USB stick because all colleagues come with video or images or Short talk on a USB stick and there are often issues then the student size So first question nothing works. Oh, it should be very easy, but When nothing works, I have nothing to do. Oh very well, but Unfortunately I come and everything works again and my password never works. So this is the second line of defense But I can change the student's password. So that doesn't the computer is way too slow So this is always about Windows which is making We don't know what Where is the application it is the last line of defense of my students They don't find the application then all my work suddenly disappeared. Oh, you know students never say they work so it is the ultimate line of defense but so and Just a remark. How can be this computer so old? You know in French schools generally computers are five years old or even more and young people look to have like to have just breaking news This computer is five years old and That is interesting. It works very well when used with Debian I have been pushing newly new solutions for a long time in my school With the few success Between 2005 2010 We had the complete room Using Gnolinix it was a distribution to make physical measurements and a few teacher Teaching that curriculum so each of them knew the peculiarity of this room And they knew that it was not windows, but that did not disturb Them so they could use it and it worked Later More people came in the same room because of the curriculum has disappeared from French programs and then they are required to use windows because My operating system was very foreign However, the US issue Nowadays every people is using Android. So people are not Rigid as they used to be so when something new appears they just adapt However My colleagues are still resisting the change. For example, all of them want Microsoft office, I don't know why because students only have access to LibreOffice Fortunately enough both are compatible for the files issued by teachers We can suspect that this is due for to Microsoft Landing free as in free beer free licenses So this has got a long success Among the oldest bootable media based on Gnolinix, you can count we freed a city it was live CD room with an educational distribution It was made by members of the association offset between yours 2002 and 2007 and the most successful release Which was tempt version 1.5 has been downloaded from a source for more than 100 or thousand times in year 2005 The feedback we got Taught us that People enjoyed Empowering old computers in a virus safe environment Because in primary school, which was our main target Computers may be 10 years old and at that time They were using Windows 95 in 2005 and you can imagine how many viruses they got every day So for 10 years now bootable USB sticks are more convenient than DVD ROMs Just become because one can save some personal content on them and So it is slightly customizable Freduc USB is the hell of Freduc city you have here Useful you are L usb dot Freduc dot org You can find every explanation here It is a derivative of the Canopix distribution made by Klaus Knopper, which maintains this custom Debian distribution regularly Used to be one new version each year at least I remaster it at a deep level So I uncompressed completely the file system make some changes and fold it again How do my students react to such an environment? So when they see that for the first time They It is easy to Save them just use the USB stick plug it in and start your computer After a lot so it's not that difficult and as far as I could see The tame of adaptation of my students is roughly 20 seconds Ten years ago they sent me oh the windows is a bit strange Nowadays they are very proud to recognize Gnolinx, but because they know something about Gnolinx. So teams are changing As they generally succeed to do the work I assign them they are proud and I say them that they are officially becoming hacker and hackers Girls appreciate to hear the name hackers, which is the feminine form of hacker in French language I don't have enough time to develop the few application we have here I shall show you in the last minutes or during the costume session. So there are some specific Scientific applications here pie acido basic. It is about chemistry Jonglage, it is about mechanics of the point For example, you can take a film of somebody playing with balls for example football ball and make Make a simulation Using the rules of physics and see how it works Pie make a video. So this is about measurement on video files, but there are many of them Let us take let us talk about Scientific experimentation During the workshop I shall mostly talk about The XPI's box which our chairmaster knows because we are working with that So this box features Something like no oscilloscope with four channels and a much much more, but back to Experiments, you know that currently people make confusion between science and faith Both are different things If we go back in European history the Maybe you know the history of Galileo Galilei Who was shoot because he pretended by our was turning? at the same time the holy office that is the Christian Topmost authority Used the books which are not really free license Free licensed It is Bible. You cannot change the Bible if you are not in this topmost office so Galileo we were shoot and On the contrary he was proposing free science because people Were invited to recompile his knowledge Of course you needed some drivers some Hardware you needed to have something to Absorb the sky So we did not see by my cavideo and Wanted to make the focus on expires So it is a small embedded system when I say it is more it is real small this size and Around top when my students drop it it still works. Okay, that makes a big difference With the oscilloscopes Just try to throw an oscilloscope and you will see whether it works Longer so this one is released and the free licenses both For the software and for the hardware Currently there is one free license for hardware which is released by c er and The OHL license is a good license for free software Ah students who have to learn coding and programming Recognize that new Linux is a good distribution because it was made by hackers and Targeted to hackers at the begin. So you can find acute tools that that is for example If you want to make something in a cook You can use a knife. A knife is something sharp. You can do very precise things with a knife When you are using Windows tools, it is like making it with a spoon Very difficult to make sharp things with a spoon And you have loads of libraries just one apity install away When my students are using Windows, they generally use not pad plus plus They use B stick comes with a Gini pre-configured and they have quite the same environment and Most of the teachings begin with JavaScript and Python more precisely Python version 3 However to feel the advantage coming with Debian they must to be somewhat advanced so They need to have a personal project and then they feel the gain of having powerful distribution So that's all We can begin the question session if we have some time left. I just deploy here view of educational applications Coming with the Debian pocket So are there any questions? Yeah, there's a microphone from you Do you have any reason to use? Knopics instead of Debian live which is in my opinion is more easy to configure and so it is just an historical reason When fast live distribution existed Knopics was among the first and Freduc city was just a few months before it was based on an over Live system which was made by Raphael Herzog But we stick to Debian a tool no pics because of that and I am trying to use Debian live Which is a powerful system. So I Could make the same distribution, but at some time it's broke I did not understand why so I must learn it and I feel it is more powerful Yes, you are right. I'm not sure. I just went for several years ago to remastering topic CD And I think this process is quite Stressful and Debian life is yes. Yes. Yes. I I know So we have one minute left some other question Thank you for the talk Have you already looked at Debian edu? so We should begin to work together The reason why I did not collaborate with Debian edu is because in I am not rude in my school So I cannot deploy a system like Debian edu. We already have system based on Debian but with some proprietary additions and That cannot be changed so I focused on Developing an environment with educational application which Debian edu is not currently There are a few links to Educational application for and users, but the main focus of Debian edu as I Thought maybe it is different now is rather for assist admin Working in schools. Okay. Yes, you're right about the main purpose. I managed to To deploy it actually in just in one room in one in one classroom and It helped me to deploy Lftp, no Booting booting via network. Yes Yes, that was the way we booted in the room which I must Give back to Windows in the past. So Unfortunately, this is ancient history for me But maybe that can change because times are changing students are knowing Increasingly aware of no Linux and maybe young teachers know how it works. So as older teachers Finishing the career Maybe some change will happen soon and we shall work together. I think it is the way to go Thank you Okay, thank you very much and a round of applause for George. Thank you for the talk Thanks
