 Good afternoon. I am really delighted to be here to address the faculty members who are participating in engineering mechanics. So, I am going to talk about some topics that are very close to my heart. IT literacy through open source software. IT of course refers to lot of things, not just programming, it also refers to simulation, buying train tickets online and stuff like that. So, we are actually going to talk about that and how to do it through open source software. And I am going to talk about two methods that we have adopted to spread this. One is through something called textbook companion. The other one is spoken tutorials. I will explain both of these. So, I have four parts in my talk. These are the four things and I will begin with free and open source software. I will first explain why free and open source software is important to us. This is one of the most important slides in my talk. First of all, it is important to realize that the commercial software is very expensive. Some of us may not realize this because software is not very expensive for academic institutions and whereas it becomes lot more expensive. And of course, you know, it is not clear how many of our, well, it is not clear whether we even know the price of software, especially our students. There are heavy penalties if unauthorized software is used by industry. I have some stories here. I would like to share them with you. First of all, this story from Italy. There was a software raid in one of the Italian companies and during the raid, they identified one illegal copy of Microsoft Office and there was an out-of-court settlement so that there would be no court case filed against this company. And the out-of-court settlement was this company would count the total number of machines it had all over the world and multiply that by per copy cost of MS Office and that would be given as damages. And as a result, this company ended up paying 20 million dollars as damages for having used one and only one illegal copy of Microsoft Office. And of course, 20 million dollars correspond to about 130, 135 crore in the current exchange rate. Now, the next one, I want to tell you about an experience we had in this very same room. In this very same room, I was teaching the controls part of the embedded systems course at IIT Bombay. There were about 25 students in the class. They were pursuing M. Taken PhD and I asked the students how many of them had used Sylab. I was going to use Sylab in this course and out of 25 students, only one raised his hand and in fact, I became really angry and sorry, in fact, I scolded him why he used Sylab, why did he not use MATLAB like everybody else. Then he told me that he worked in an embedded systems company before coming to IIT for higher studies. That is, out of the 25 students, he was the only one who had gone and worked in a company before coming to IIT for higher studies and whereas everybody else, all the other 24 students had come directly after their studies. Either they had done bachelors, they were doing masters or they were done masters and they came for PhD and they had not worked outside. This single person worked in an embedded systems company in Pune and he wanted to use MATLAB. And of course, it was a startup small company. Probably, it had only some four or five people in the whole company. The annual turnover itself would have been just about 5 to 10 crore and so his boss told him that a copy of MATLAB for them would be very expensive. Can somebody guess? I see that some of you are responding in this, can somebody guess what is the price of MATLAB for this embedded systems company? You can reply on chat. What is the cost of SILAB? Somebody says 1 lakh, somebody says 2 lakh. All right. So, somebody says freeware. Sorry, I am not talking about SILAB. Sorry, I am talking about MATLAB. What is the cost of MATLAB for industry? He wanted to use MATLAB. His boss told him MATLAB was too expensive. So, people have said 23 lakhs, 7.5 lakhs, 25 lakhs, 10 lakhs, 5 lakhs. Okay. Fine. Fair enough. You have given enough feedback. His boss told him that, remember it is an embedded systems company. It is an embedded systems company. Finally, whatever they develop should be embedded in an IC and should be delivered. That is whatever they create using MATLAB should be delivered. And he wanted to remember, he wanted to use MATLAB in his company. And his boss told him MATLAB was too expensive. And what is the cost of MATLAB? That is the question. So, his boss told him a copy of MATLAB for the unlimited use that they had in mind would cost 2 crore rupees. 2 crore. Okay. So, somebody has written $99, not at all true. 2 crore rupees is what was told by his boss. And so, he told this student, this employee that MATLAB was too expensive. They could not afford. He could use C, Java and so on and so forth. But if he insisted on MATLAB, he could resign and go. He didn't want to. Okay. In the sun lever, such a famous company has only one copy of MATLAB. Anyone who wants to use MATLAB should come at 7.30 in the morning and occupy the chair. Nobody else can use MATLAB on that day. Vipro also has one copy of MATLAB. Those who want to use MATLAB should block their slot. I want to use it next Thursday 4 to 5. You block it now so that you get to use it. Okay. So, our, because of this, so I asked, we did a workshop with Vipro people, Mission 10x people on virtual labs, single bodied system lab. And I asked this person whom I was working with, what would Vipro do if somebody brought an illegal copy of MATLAB within their premises? So, he said three things. One, he will be dismissed. Two, he will be put in jail. Three, there will be a court case. Okay. So, why did Vipro, why should Vipro do all this? Why do you think Vipro should all do all this? Heavy penalty. They possess one copy only. Okay. Well, actually I have, I would ask this. Okay. So, the, actually I asked, how many computers do you think Vipro has? Remember the Italy story? What happened when there was one illegal software? Right? So, so that's the reason Vipro will go bankrupt if they apply that rule. So, because of this, our small and medium scale enterprises don't use any software. Commercial software is very expensive and they are not aware of open source software. We don't teach them in colleges. We don't teach our students how to use. Commercial software is like a book that they cannot take outside our college premises. Okay. This makes small companies uncompetitive and there is no alternative to FOS. Remember, this is a very important slide. There is no alternative to FOS, especially when you go to industry. Okay. But there are problems with the open source software and this is possibly one reason why people don't use open source software. It is that good documents are missing. People don't know how to use them and then there is a lack of support, wrong impression about the quality. So, we decided in our project that we would address these issues. These three we would address. Okay. Now, I am going to explain the procedure that we followed to address these issues using Sylab. Sylab is open source software. It is equivalent to MATLAB. Okay. So, I want to talk about that. It is a very good substitute for MATLAB. It has about 95% compatibility with MATLAB. It also has tool called XCOS. It is a great replacement for Simulink. So, Sylab and XCOS together can be used in the place of MATLAB and Simulink. It also has, of course, it is free and open source. It is easy to use. It has excellent computational environment. Whatever good tools that are available in MATLAB are also available in Sylab. For example, INPAC, ISPAC, LOPAC, same as MATLAB. These are all computational engines. These are the ones that ensure that the final result is correct. The computation happens fast and so on. And there are also, there are software packages that are not available for MATLAB, things like DASIL, ODE PAC and so on. Okay. Because of the licensing, because some software could say that if any other software uses this, that software should also become free. So, commercial software will not want to use that. Okay. How reliable is software? How reliable is Sylab? I do not know if anybody knows about CNES. CNES, you know, is Francis Isra. Okay. And you may not, even if you do not know CNES, you would know the product of, popular product of CNES. It, they launch Arian rockets. CNES relies on Sylab for many critical calculations. Okay. So, how do I know this? Well, actually in the world's first ever Sylab user conference, there was, on 1st July 2009, I was asked, I was invited as a keynote speaker and the Sylab team paid my airfare. I went there, I was a keynote speaker and I talked about the National Mission on Education through ICT. Okay. And there, a senior manager of CNES gave a talk. I have downloaded that talk. Let me see if I can get that for you. Okay. So, this senior manager's name is Cherry Martin of CNES. He gave a talk, use of Sylab for space mission analysis and flight dynamics activities. So, what is Sylab used for? Let me see if I can make this slightly bigger so you can read it little more easily. So, he says Sylab is now widely used in CNES in various engineering fields such as telecommunications, RF analysis, navigation, attitude control systems and then he says this presentation explains how Sylab is used at CNES and then he talks about, he went on talking about how, in how many different ways Sylab is used and let me go to the last slide. Okay. So, he says Sylab is widely used within CNES flight dynamics departments. It is used for all kinds of things, orbit propagation, orbit geometry, reference frames and models, etcetera, etcetera. Okay. So, his name is Terry Martin. CNES, if you just do a web search on this, you will look at this PDF file. It is available on the internet. So, you know that many of our satellites were placed in orbit by Ariane rockets and Ariane rockets themselves were launched based on calculations from Sylab. So, obviously if Ariane rockets can be launched with Sylab, we can very well use Sylab for our classroom activities. This is the talk that I talked about. Okay. So, let us get back. So, this is to tell you if somebody comes and tells you Sylab is buggy, do not use it, do not believe them. Okay. Sylab is great software. So, I am going to use Sylab to explain to you the things that we are doing to promote open source software. Okay. What are the problems to the open source software? Good documents are missing. There is a lack of support and wrong impression about the quality. One of the early projects that we started to address this difficulty was the textbook companion project. So, what is the textbook companion project? Basically, I will first tell you the motivation as to why we started this project for documentation. Remember, we are trying to get documentation for open source software and creation of documents is a very difficult task. You need people who are mature, people who are good in English, who do not make mistakes, who do not make spelling mistakes, do not make grammatical mistakes and you also need people who understand the subject. Right. But then these people are very few. They also cost a lot of money. So, how do we do this for open source software? We have a lot of students of course. So, what I thought was why do not we use students to create to address this documentation issue? Okay. So, unfortunately students are weak in documentation. You ask them to write a code they will write but ask them to write a report on it. They are going to do a bad job. So, we came up with this. I said let me see if we can solve an inverse problem. What is the inverse problem? Ask the students to create code for existing documents. Okay. So, that is what I have. Students can create code but not write documents. Okay. So, we solve the inverse problem. Good textbooks are good documents. So, we can say if you take a good textbook, people spend a lot of time to write good textbooks and in fact I spent 10 years writing my book Digital Control. In fact, it created a lot of problems at home. So, in fact I have promised my wife that I will not write textbooks anymore because it would take a lot of my time. People spend a lot of time writing good textbooks. So, if there is a good textbook it has good solved problems. Why do not we take the code and write, why do not we take solved examples and for them write Sylab code. Okay. In other words if you execute Sylab code it should give the answer given here. Okay. Let me see if I can, in fact I will show you shortly what I mean by this. These are known as textbook companions and good students from most colleges can do this. Let me see if I can, I have already opened this website. I have gone through this website called cloud.sylab.in. I hope you can see this. Right. Now what I want you to do is to select a book. I am going to execute one of these books and somebody select something. So, should I take something in fluid mechanics because many of you are from mechanical engineering. So, let me take fluid mechanics. Okay. And I have lot of books on this. Would you want to select a book now? Can you see it? So, should I select a Douglas? Okay. If you, somebody has said 7, book number 7. What is 7? Okay. Fluidization engineering by Daiso and Levenspiel. Okay. So, it says then which chapter? Okay. So, which chapter? Okay. Chapter 9. Solid movement, mixing, segregation and staging. Okay. What example? Vorticity. Somebody says vorticity. Anyway, let me just take one of them. Okay. You can see that I have made the font very large. Let me make it small so that you can see that there is code. Okay. Then I will make it bigger. Okay. Now let me execute it. So, when I execute, okay. When I execute, it actually, it actually, it actually, it sends this data to, it sends data to the cloud which is in Bangalore in this case. Garuda cloud is something that we are using. But anyway, this is all available for all of you. You can go and try it out later. What I will do is, let me take another example so that I can show some pictures also. Let me take control theory. Let me take automatic control systems. Let me take frequency domain analysis. Let me take an example. Let me take body plot. Okay. So, here is a program. You can see that there is a program for this problem. For this book, okay. This is the topic. This is the book. This is the chapter. This is the specific example. Okay. Let me execute this. What I will do is, I will come back. You can all try it out. This is cloud.sylab.in. And if you have good internet access, it will work. Okay. In case you do not have internet, you want to access this, all the books are available here. You see this textbook companion project. And if you press this, it says completed books. Let us go to completed books. Okay. Once again, it gives lots of topics. So, let us go to fluid mechanics. It says all these things are available. Let us take this Douglas. Okay. Here is the book. Author, contributor. Who is the contributor? Chakra, B.Tech. J. Chakra, B.Tech. Others IIT Bombay. So, we can take some other book. Let me see. Fox and McDonald, for example. So, this is written by Eswar Prasad, B.Tech. Student, Mechanical Engineering, NIT Trichy. And the college teacher who mentored him is Professor Shiv Prasad, Shivraj Deshbukh. Well, actually he is our student who did this mentoring. But then, generally, for every contributor, we expect the college teacher to be the mentor. And then, let me just see. Now, you can download all the examples of the entire book. Okay. Or you can download the PDF file of the entire book. Or you can choose a chapter. So, it is possible when you play around with this, you will realize that you can actually have lots of things. Now, you can download all the examples of the entire chapter. Okay. Download PDF works. You can see this coming down here. And it says all files have finished downloading. Let me click this. Here it is. So, this is what I downloaded just now. PsyLive Textbook Companion for Introduction to Fluid Mechanics by Fox and McDonald. By Eswar Prasad, who over-created it. Here is a description of the book. Okay. This is the thing that I downloaded. Let me make it bigger. Unfortunately, this font is not very good. Let me just go to first page. So, I made it very big. Okay. This is what I downloaded. Book details. Okay. So, I can say that here it is. Now, supposing I am going through a book, going through this book and I am going through example 3.01, then all I have to do is to click this. It will immediately take me to example 301. You make it bigger so I can actually see it. Okay. So, this whole thing is a 116 page book as you can see in the top. Right? The whole thing is a 116 page book. So, what we did was, let me come back to my talk. I wanted to give you a flavor of this textbook companion project and some people say, can we able to modify any complex system for the design purpose using PsyLive? Yes, we can do everything. Example, gear dynamics. Of course, you can do it. Text is not clear. Please share through desktop sharing that I cannot do. Some people say that it is very good. So, here is an example. We did an internship project during the summer of 2010. Fluid mechanics by Fox and McDonald. Control system designed by Smarajith Ghosh. Engineering mathematics by Kresig. Three more created by IIT Bombay students. So, when we did a pilot, we found that one student can complete one textbook companion in one month. Okay. So, good students from most colleges can do this. Students from all colleges can participate in this project. I have some... So, what is the procedure? One can choose any standard textbook, code the worked out examples into PsyLive, get the correctness certified by the subject expert, get Hondrarium and they get rupees 10,000 for students. For the mentors who are often college teachers, in fact, all of you can become mentors. You can ask your... The brightest student in your class to create textbook companion and we give you a Hondrarium of rupees 5000 rupees. And we give summer winter internship to create textbook companion. All the details are in our website, PsyLive.in. How to participate in that is available in our website. So, for example, if you see here on the left hand side, it says internship, guidelines for coding, Hondrarium, flow chart, completed books. So, flow chart actually tells you how to do that, how to participate in that is also given here. How the students can get internship is also explained here. So, textbook companions are community developed documentation for FOSS. We have a large number of books. In fact, we completed 200 books in progress 200. We are spending 10,000. We are giving to the student 5000. We are giving to the faculty member and then we have our own administrative work. So, that actually kind of doubles this. But then in 30,000 rupees, we are able to give this which you can even execute remotely. So, every textbook companion is available as a PDF file. It can be downloaded free of cost from SyLive.in. It can be printed as a book as well. And then to understand this, you need the original textbook. For example, let me show you, let me go back to this book. For example, if you want to understand this book, understand this code, you need the book. So, we give only code after code after code. Example 3.01, example 3.01 D, 3.03 and here is the result. If you run SyLive, this is what you would get 3.03, 4, so on and so forth. So, because we do not review anything from the textbook, there is no copyright violation. So, I already demonstrated this on Verodoc Cloud. Of course, we did this for SyLive, but we can extend this for other FOSS systems also, other open source software also. At this point, we will just see whether we can extend this. I mean, we can extend this. I want to go to the next topic now. What are the FOSS activities at IIT Bombay? By the way, FOSS stands for Free and Open Source Software. We are working on Python, working on OpenForm. How many of you use Fluent, which is a computational dynamics, fluid dynamics software? I think CFD is taught in most mechanical engineering departments. So, this OpenForm is an amazing open source equivalent and then I am going to explain to you later how we can conduct workshops for you. It is FOSS alternative to Fluent. That means you can legally download and use it. And if there are any electronics engineers amongst you, we have a software called OSCAD, which is a FOSS alternative to ORCAD. OpenFormal for computer science people and then we are also working on giving a FOSS alternative to LabView. Some of you might know is used for data acquisition and control. Python is a very good software that we support at IIT Bombay. It is a very powerful programming language equivalent to C. In fact, CBAC has introduced it in their curriculum. We can learn even if there is no much of prior programming background, it is very popular. It is used in MIT in Boston, UT, Austin, etc. CBAC has introduced Python. And then I already told you OSCAD is a replacement for ORCAD. It is available through OSCAD.in. You can tell your friends in electronics department, electrical engineering department and instrumentation engineering department to try out this software OSCAD.in. Now for you, let us see whether I can go to CFD.Fossy.in because you are all mechanical engineers or chemical engineers. You are likely to be interested in fluid mechanics. So, this is the computational fluid dynamics software called OpenForm. But the way you look at it is go to CFD.Fossy.in and then you can see a lot of things are there, home, teachers, downloads. I was looking for Spokane tutorials. So, it is actually available already. If I click this, so for example, I can even play this. Hello and welcome to the Spokane tutorial on modeling turbulent flow in a lead driven cavity using OpenForm. In this tutorial, I will show you solving turbulent case in OpenForm and plotting streamlines in ParaView and so on. To record this tutorial, I am using Linux operating system to version 12.0 and press enter or type LS and press enter. So, let me just see flow. This is the turbulent flow. This is flow over flat play, simulating Hagen-Poisel flow in OpenForm and so on. So, these are available, but it is also available. In fact, we have, it says for basic level OpenForm tutorials, click here. These are advanced tutorials. Nothing has come. This is our website which I am going to show later. I will show you, I will take this opportunity to explain to you how to locate our videos. For example, I was trying, I was showing you something from OpenForm. You can see this here. OpenForm, in what language? Of course, it is available only in English at this point. So, let me locate the tutorials. So, all the 12 tutorials come. The first one says installing and running. Second one is says creating simple geometry, creating curved geometry, simulating flow, supersonic flow, 2D laminar flow, turbulent flow. How to do all of this in OpenForm is explained here. So, I would encourage all of you to go by press it, installing and running. So, you can actually see this. And welcome to the spoken tutorial on installing and running OpenForm and ParaView. In this tutorial, I will show you how to install and run, solve a late-driven cavity case. To record this tutorial, I am using Linux operating system. I can even make a full screen. OpenForm version 10.04, OpenForm version 2.1.0. I can of course go. ParaView version 3.5. A little advance. Please visit our website on this. Scroll down. It tells you how to install it. In the command terminal, type mkdir space dash p, the OpenForm website. So, here is 3D. I am just going to fast. I do not expect you to understand this, but I want you to know how to use it. Let me see whether he has some figures. There is some figure. Scroll down the object inspector menu and go to mesh parts. Uncheck internal mesh. So, you can see that how to do this. So, I told you about OpenForm. About Sylab, we have already seen quite a bit. Openformal for formal verification of software and hardware. And then we are also building a false alternative to LabView. We have open source hardware. We also have a hardware project where our students are working on it. So, I talked to you about two activities. One is the textbook companion. And the second one is the spoken tutorial. The textbook companion you have already seen. Now, about spoken tutorials you saw, but I will give a little more information on spoken tutorial. How we can download the PDF format of books on cloudsylab.in. Please explain. I will see whether I can explain that. So, actually this is where you are supposed to download PDF. Is there any quiz? Yeah, there is a quiz. For people who undergo our workshop, I will explain that. Do you have any plan for open source workshop in future? We are ready to conduct workshops. I am going to explain that shortly. Could you guide on any open source software, finite element analysis, which could substitute high end software similar to the one you have for CFDS? Yes, look at this openform. Openform is that software. We can conduct workshops for you. What else? Will there be any training course for CFD? Yeah, we will conduct a workshop on openform for you. I am going to explain to you how to do that. So, I am going to cloud.sylab.in. It is a lot faster now. So, I was going to show you control theory with the chapter. Let me just see. You see that the plot has come. If you want, I can download it. I think right click. Copy, save images and so on and so forth. So, all that is possible. So, let me go back. I think I have to go here. So, here a PNG file, I close this from here. Now, for example, I can change the value here. So, instead of 2500, suppose I want to make it 5000. So, now I got some other plot, but you can see here now. You can see here now it is 5000 because I made it 5000. So, that works. And of course, you can write your own code here. Let me delete this. And then I can say 4, well, yeah, 4 plus 2 is okay. Execute. It gives answer as 6. Then I can say things like A equals 1, 2, 3, 4, 5, 6, 7, 8, 0. Then I say determinant of A. Then calculate the eigenvalues using spectrum command. And then execute. It gives the answer, right. So, actually in cloud.silav.in, you can carry out your own calculation. But you can also carry out many of these calculations. Let me go back to the slide. Okay, I am going to talk to you about supercantitorials in the remaining time. And I am going to tell you how our team is glad to organize workshops for you. And because of the shortage of time in this, we actually wanted to conduct a silav workshop as a part of this. But then we found that it was too tense. You had already too many things to teach. So, what we decided was that I will give an overview of whatever we are doing. And then we will tell you how to participate in this. And then you can contact us. So, I am going to explain to you how to do that. Okay. What is a supercantitorial? Well, actually I can create a demo also. Let me do a small demo for you. How to create a supercantitorial? It is actually very easy. I am going to use a recording software for doing this. I am going to record a part of the screen. And I am going to do this using silav. So, I am going to record this part of it. Let me start the recording. Good afternoon. Welcome to this demonstration on the creation of a supercantitorial. Let me create a matrix 1, 2, 3, 4, 5, 6, 7, 8, 0. Let me calculate the eigenvalues using the spectrum command. Let me create a 3D plot. Okay. I will bring it inside. I think that will be good enough to get an idea. Thanks for joining Goodbye and Jay Hind. So, when I do that, I have already created this tutorial. 4, 5, 6, 7, 8, 0. Let me calculate the eigenvalues using the spectrum command. Let me create a 3D plot. Okay. I will bring it inside. I think that will be good enough to get an idea. Thanks for joining Goodbye and Jay Hind. Okay. So, you notice that it is extremely easy whatever I created. In fact, you know, this is something that I can... Good afternoon. Welcome to this demonstration. I can advance so that you know that I am not talking. 3D plot. It is a recording and I created that recording for you. Okay. I will bring it inside. So, this is how a supercantitorial is created. In case you are interested in creating a tutorial, I can show you where it is available. In case some of you want to know how to create a tutorial, using popularly available software. So, we have something called spoken tutorial technology. And we will do it only in English. Okay. So, for example, what is a spoken... How does one create it using CAM Studio? By the way, CAM Studio is available on Windows. So, you can create it using this. Right. Okay. Now, I told you about training. In fact, now that I am here, if you come here, you see these workshops, certificates, organizing workshops. You click that. And let me make this slightly bigger so that you can see this. And if you come down, you would see who is handling these workshops for different states. For example, for West Bengal and Odisha, Pail Mukherjee, for Goa, it is Sriptimore, Gujarat, Madhukrithi Srivastava, phone number is given for all of these people. Through them, we conduct all workshops including Wappan firm, including Sylab. We can conduct it in your own college for your own students. Right. So, what is a spoken tutorial? It's an audio video tutorial of 10-minute duration. It is created for self-learning. It is a screencast. Whatever seen on the screen and spoken can be recorded, which is what I demonstrated to you. I created a matrix. Then I calculated the eigenvalue. I recorded it and I played it back. So, this is something you can also do. But then what we do is we create spoken tutorials. We put in a lot of effort so that it is suitable for self-learning. Right. That is the reason why I'm confidently telling you that we are in a position to conduct workshops in your own college for your own students. Right. So, it takes only 1 MB per minute. In a CD, you can pack about 10 hours of spoken tutorials. The spoken tutorials are available at spoken-tutorial.org and videos are available for free download. Dubbing. We can dub only the audio. In fact, let me see if I can play some of that. In this page, I have some. Let me see if I can play Hindi. Okay. That is Hindi. Let me play Marathi. So, it says first C program. So, it is possible. Of course, in this, what I have is different other things. So, what you would have noticed is our videos are in English. For example, I played you C programming. Video was in English, but the spoken part is in Marathi. It's available in all over 22 languages. And of course, I can play all of this, but then it will take time. So, I will skip this. On our website, of course, all of them are available. Just to give some numbers, let me just show you how many we have. For example, we have 121 in Bengali in English, 472. Gujarati, 224. Hindi, 200. Marathi, 206. Nepali, 99. Punjabi, 49. Sanskrit, we have 30. Tamil, we have 214. Of course, for us, all languages are equal. It is a question of enough translators and people who give voice and dub. And the moment we find them, we can do that. Actually, we are doing badly in the northeastern languages. For example, if you see, Bodo, we have only one. We have Kasi, we have only one. We would like to dub these in larger number. I said I will play Sanskrit. Let me just play, see if I can find it. I can select all first categories. Librofiskalk, parijayaha. Ittasmin spoken tutorial madhyay. Swagatam. Asmin pathay, vayampathamaha. Librofiskalk, ittasya, parijayaha. Okay. So, you get an idea of what it is. So, video is in English, but audio is in mother tongue. And it is useful for children who are weak in English without affecting employment. Okay. All you need to use it is an ordinary desktop or a laptop or Akash and an earphone for listening, as a 20 rupee phone that you get in the flights will do. We restrict ourselves only to open source software. So, every tutorial of ours can be practiced by everyone. So, for example, what I mean by this is, okay. What I want to do is, this is the way I want all of you to practice if you want. Is Sylab running here? Okay. Let me, I will just demonstrate using Sylab here. Let me go to Sylab and let me select English. Let me locate the tutorials because I want to explain to you how to learn by this. So, let me say getting started. Okay. What I am going to do now is I am going to, what I call as un-maximize. Have you seen, have you done something like this? You listen to a command, pause it, try it out on this. You should have them side by side. Okay. In fact, this is what faculty member from Government College Amravati told me. I conducted a CEP TechWip course there and they said, it is known as side by side method. Anyway, I will come to that. So, how does one use spoken tutorial? Listen to a command, pause it, try the command on the software. If it works, go to the next command. If not, rewind and listen to it. Repeat until the tutorial is completed. Okay. So, then we said if the spoken tutorials are suitable for self-learning, why do not we conduct workshops through them? Okay. These are known as self-workshops, spoken tutorial-based education and learning through free, fast, steady workshops. Okay. And our workshops are of only two hour duration. Okay. Remember, on our internet site, I gave you the, I told you how to locate the names and phone numbers of our contact people. So, those are all available there. Okay. And they will help you conduct these two hour workshops. During the two hour, you will learn some of the possible tutorials and learn the methodology to use the tutorials. You can complete the reminder at your leisure easily. Okay. We also conduct online tests about two weeks after the workshop. This is also offered free of cost. And we give certificates for people who pass online tests. And the students learn at a convenient pace, learn using a language of their choice, and all can come to the same level. Remember, each one has got a headphone and they listen to it. They practice side by side. And we can provide high-tech solutions to linguistic minorities also. And of course, we, this helps national integration. All students learn from the, all students and also faculty members learn from the same tutorial from Kashmir to Kanyakumari. It's quite different from train the trainer program. Everyone learns from the same video. And about 75% of the students pass online tests. So, we conduct about 3000 workshops per year. At present colleges, we have gone to about 1000 colleges. It is likely that in many of your colleges, we have already conducted these workshops. Maybe there is somebody who is already ready to conduct these workshops for you. They can conduct open form workshops for you. They can conduct sila workshops for you. And now we are going to schools also. There are many interesting case studies, but I'll skip this because of, we are running out of time. So, we are ready to conduct workshops on many of these. And then, and it is done absolutely free of cost. It requires only two hours. And maybe in your college, there is somebody who knows this already, who can already conduct these workshops for you. A lot of people are coming to our website. I showed you. In fact, let me show one other thing, one other feature that we have on our website. So, if you see here, you will see the workshops that are happening. For example, upcoming events and workshops, you can actually monitor that. For example, tomorrow, there are workshops in Namakal, Coimbatore, Chobhari, Virudunagar, Isawal, Una, Kanchipuram, lots of other places. You can just see where these workshops are happening. They are happening all over the country. Typically, okay, actually our staff member is in Tamil Nadu. There seems to be a lot of workshops happening in Tamil Nadu. But the states where this is happening in a big way, if you visit this place, let me just come here. See this. I clicked that. Workshop statistics, okay. The maximum number of workshops have taken place in Gujarat. We have trained 42,000 students there. Tamil Nadu comes second. Third one is Maharashtra. Madhya Pradesh, Uttar Pradesh and so on. Various states are coming. You can also go through this like this. Those of you who are concerned that in your state, we are not doing enough, please come and contact us. We would like to contact as many workshops because anyway, these are all conducted free of cost. And you can also see this. I press this India map. So, it took me to this India map. Let me take this to Gujarat. You can actually see the, for example, 845 workshops have taken place. The latest one is Katraj and then Uttar Sanda, Karad. So, let me take this Surat. It says that where did this workshop take place? It happened in Surat. It happened in this college. Srimati Thanuban and Manubai Trivedi College of Information Sciences. 67 students participated. So, you can actually see this for your state. I can of course sort it by city here. So, you can see that workshops happening in Ahmedabad. You can see the first categories that are taking place. You can actually sort by workshop, sort by number of students. Now, you click it again. So, this college says, Chottubai College says that they trained 1,632 students in Linux on a given day, 18th of January 2012. You can see that on 20th of February 2013, recently in Rajkot RK University, they trained 400 people on C and C++. So, such a facility is available. We are providing all this absolutely free of cost. You can make this available to your students. So, let me come back. I would like to wind up. I have only 5 minutes. So, the vision is there is no programmer shortage in 5 years. As I mentioned earlier, I conducted a TechWip course in Amravati Government College, Engineering College. I conducted a latex self workshops. Participants made latex based presentations at the end. And they said side-by-side learning is method. Side-by-side learning method is very effective. Just to say that in Government College Engineering, Amravati, where the participants were in the age group 30 to 50, at the end of it, the teachers, they made presentations using latex after just a 2-hour self-workshop on latex. So, this we are conducting in a big way, latex workshops. By the way, all the slides were made using latex. So, I will now go to, I call this side-by-side learning method. Remember that video on one side and software on this side do it side-by-side. I am going to skip all this. I am ready to, we are ready to transfer Spokane Tutorial Technology to all interested people. Our project is funded by NMEI CT, MHRD Government of India. To conclude, Spokane Tutorials and FAS have the potential to improve your employment potential. Actually, what I mean by this is your students employment potential. Spokane Tutorial is imparting IT skills to a large number of students already. It is also beginning to get adopted in universities. It is a useful tool in all skills development as well. It is a powerful tool for a multilingual country like ours. We invite you to benefit from our activities. We also invite you to collaborate with us. So, thank you. Those of you are interested in participating in either textbook companion or Spokane Tutorial can contact us. Thanks for joining. Goodbye and Jai Hind.
