It's not how you that's not how you aim. I want to aim through this Remember that Fine, I will fast travel out of here. I could try to Do the thing I got to get in here Skills to My little corner I came in So we got to aim this up there we go Mr. Stark, I can touch this guy I can see the Sun's okay. This is give me give me way Way fast travel locked. I'm doomed. I reload to save or reload the checkpoint. Can I do that? We have to I'm sorry guys. I just have a knack for breaking things All right, what are we doing? Get to the incinerator got it. I'll wait this night. There's the incinerator. Hope I'm not too late Looks like trouble Easy clap You okay? This gang's been terrorizing the whole neighborhood the last couple of days. There's probably more of this world I know man. It's crazy. Hey, what if I look around for some it's so wild I love it. I gotta go file an incident before it's a glow-in-the-dark spider-man man. It's crazy There's something there gotta move these bags out of the way No, oh here Back that way Hear my mother call That last bag got the business here. Please be here. Hope it still works looks like everything's here an old gadget prototype Looks kind of awesome. Why didn't I ever finish it?  I can make this work. We got a web bomb boys Not really. Yes. Oh, no, I need more challenge tokens yes More spiders are on upgrades. They can fire more shots mmm What's this? Increase the blast radius sure We're gonna test our bomb chat use R. Just like web bomb Okay, they're kind of making me do it It's so funny. Oh, it's too much jazz too much Oh It's too much This bomb is too good. I love it. They may spider-man so overpowered. That's just perfect So there is weather I mean, you know, I didn't even notice because it was subtle but it's raining right now Well, I don't know if it's ever rained in the daytime. I think the rain is always a Web alert Huh looks like MJ story just got published. I Think I'll find somewhere else to stay. She's probably busy with work. I wish Harry was in town. I could crash with him Yee, new level hmm someone left me a voicemail numbers block though I can get that one skill now. Oh, wait, I already got it. I think I know that voice is that That black Freestyle gaming with the button 11 months in the row. Everybody's showing some love in the chat. Thank you so much free style of gaming Ghost re-slip close to one year. Enjoy this game. Oh man.   Oh wait. No, that's not how you do this run Oh Man does that hurt? All right. We need some gadgets. Let's see up. We're gonna hit it Okay, spy the button spy the button does whatever a spiderbot can and we're gonna grab some electricity electricity electricity Hit this guy. We're gonna. Oh, no.

Oh The pain. Okay, then we're gonna grab this we're gonna good. Okay, hit him in the face and we're gonna They're all dead. I could fast travel to all of these All these years. Did they just unlock fast travel or am I just Am I dense because it's I've been I've been flying everywhere manually. Oh My goodness to available skill points That's really cool, I like the char jump epicenter Well, you can't say no to that chat You can't say no to that. All right. What's next? I Guess I can do a couple more research centers. These these ones I haven't done Well, I messed that up Somehow I end up behind that thing under pressure Station monitors water pressure down to the individual building structures above four stories use water towers to augment the city system The idea is to identify problems before they spread, you know Pressuring this building is all over the map. I need to find out why the water towers connect to the city's system at the Four-story mark. I'll scan the pipes. Try to see where this starts Pipes are fine up here. Whatever's causing this. It's lower


Yeah, we have a question from Dordo. He makes several times this question. He wants to know your opinion about the centralizing system on Bitcoin network Requiring personal data for usage and thought of future of that Yeah, I think the I think most of my talk was about this but I'll focus just on the revealing personal data part of it because a revealing personal data is not simply a matter of a Totalitarian financial surveillance system It's also market economy We already have a system for micro payments on the internet if you want to buy any content that Effectively is priced less than five dollars The price you pay is a micro violation of your privacy That is the micro payment system we have on the internet You give your data to be consumed analyze statistically correlated so that the messaging you receive is Narrow and narrower and narrower more and more conforming to the image of what Facebook thinks you want to hear to what Amazon thinks you want to buy etc We pay micro payments through micro violations of privacy our private data is the price of entry Into the micro economy and we can do much better than that because as we develop micro payments on top of network-centric Currencies we can instead pay with currency While retaining all of our privacy Bitcoin doesn't require you to identify yourself and That is not a bug that is a feature in fact Bitcoin makes it very difficult to overlay identity on top of it the way the blockchains the banks want to build or Because that's not secure when you concentrate personally identifiable information you get hacked We have not yet found a way to secure data Nobody can secure data City bank can't secure data the large internet retailers can't secure data the NSA can't keep its data in house The idea that some Bitcoin startup is going to start doing know your customer Identification and un-team money laundering collecting all the privately identifiable information That is both ridiculous and disastrous because what will happen is that information will leak and you Will lose your privacy once again, so Bitcoin does not do identity because that's part of the design and it's actually a very powerful Part of the design because it's the foundation of us having privacy anonymity is just another word for human right


11.45, so let's begin. Good morning, good evening, and good afternoon, depending upon which time zone you're joining us from. Welcome to this webinar being organized jointly by the Water Channel and IIT Delft. We have been organizing these webinars as a way of reaching out to former students of IIT, but also to the water sector at large. Through the webinars we share from time to time the latest in water management research and education that is coming out of IIT and indeed from the Water Channel. The webinars are free to attend and open to all. We see some value in keeping these webinars open. We think that by engaging in a certain amount of sharing and exchange as opposed to buying and selling the whole water sector benefits in a way which also benefits us as individual professionals and as organizations. We are happy to have at the webinar today someone who has been spearheading the idea of openness in water education and in data-driven water management at large. He is Hans van der Quest, senior lecturer at the Department of Water Resource and Ecosystems at IIT. As a teacher, Hans champions and promotes the use of open source tools for teaching and learning. As a specialist and in remote sensing and GIS, he keeps promoting and developing tools and data sets that are open and accessible to a wide range of people who work in the water sectors, students, teachers, water managers, farmers, government organizations and so on. The latest in this endeavor is a book called QGIS for Hydrological Applications which he has co-written with Kurt Menke. I hope I pronounce Kurt's name right and it is a book I would really recommend to all of us gathered here in this webinar and I will just share the link to the book in this chat box. This is an Amazon but this is a link on Amazon but the book is also available on several other platforms. So with that brief but hopefully sufficient introduction, I would like to hand things over to Hans himself. We look forward to hearing from him and learning about various opportunities for open source learning in water management that are out there but hopefully also to understand a bit how does the open source ecosystem work? What incentives do creators of open source material have? I'm sorry is the audio clear? Can everybody hear me? Okay, okay so I'll just go ahead. So I was saying in course of the webinar we also hope to understand a bit how the open source ecosystem works. What incentives do creators of open source teaching and learning material have to keep creating such material? If there is a business model underlying open source processes and so is open source really the future of learning? Before that I would like to point out some housekeeping stuff. We would like to keep this webinar interactive so we invite you to keep sharing questions and comments that come to your mind during the webinar. You can do that in the chat box here that you can see. We will keep collecting your questions and comments and discuss them during the Q&A session which will follow Hans's main presentation. So without further ado I would like to hand things over to Hans. Hans please take it away. So welcome everybody. I think the introduction by Abraham was okay. I will add a few more things during the presentation. You've seen these poll questions on your screen so if you haven't answered them yet please go ahead. We use that also to summarize in the end a bit the findings. Okay so welcome all especially our alumni. I've seen a lot of familiar names around. Great that you can attend and I hope these slides will help you to discuss with me at the end the things related to open education. We need to distinguish a bit that open source is used mainly for source code so open source software. I had already a previous webinar on open data so in that case we call it open data or open access and this one is about open education for water professionals and I made this presentation together with Raquel Dos Santos and Jepke Koster who both work in the Education Bureau and help me with gathering statistics and advising on the presentation. Now open education we have heard about a lot of terminology in the last few years like MOOCs, open courseware, e-learning and yeah what does it mean and why are we doing it. So I would like to pose a first question to you all like if you are a developer of courses why would you do what is the most important objective you want to achieve with e-learning? Still take a minute and you think about if you yourself can distribute educational materials why would you choose for e-learning what is the most important objective for you. I see there reach more people from far away places that's a good one to learn at our pace and suitabilities I think that's also a very good one cost effective yeah could be see a few more affordability for students yeah especially if it's about open education access ideas at the global level yeah fantastic okay see the answer still coming in very good we will report those after this webinar together with the video but let's have a look at what others came up with in during workshops that we had at IHC Delft so I'm also coordinating e-learning with our partners so if you're interested in that you can also contact me it's funded by the DHC2 program and these things came up with our meetings with for example WaterNet increasing the impact by training more people on water related topics improve the cost effectiveness also mentioned by US participants here to reduce the needs for students to travel between different hosting universities that happens of course a lot in our work especially if you work in a network facilitate the sharing of educational materials between the partners also very important the sharing component also use it to update existing curricula I'm going to talk a lot about that how you do that in a proper way in developing new innovative curricula and attract more participants in that way organize professional short course in an online format so you can offer them much more often than you do with the face-to-face courses and there's also a quality control that you can do in another way which needs to be developed for online it's always used as an excuse not to do it but I think it's there's also arguments to do it and improve the quality control with different e-learning approaches very important for you as alumni is with e-learning we can also support more the lifelong learning after graduation with IHE it doesn't stop science develops insights in the world develop and it's good if we keep in touch with each other and facilitate lifelong learning through online participation and it's green also very important these days I personally want to fly less for my work and I see that e-learning is a nice opportunity for me to organize trainings in any place in the world without flying and I think it's very important also for IHE to reduce our CO2 footprint and in these days we can even add to that today it came out in the news that 290 million school children are kept home because of corona what if the schools and the facilities were there for for e-learning then this time would not get lost and you can use it even as opportunity to learn new things through the internet so a lot of advantages of doing that here at IHE Delft we have different modalities for e-learning we have professional diploma courses that can also be used in so-called blended learning mode so you have face-to-face which is then mixed with online components and available on our website as online courses there's also online courses at the master level which can also be used for lifelong learning we are thinking more to moving to shorter courses instead of the full five ECTS ones that also reduces the price but we also think that there is a more interest in shorter components and I would be glad also to hear that from you in the discussion so you can make some remarks on that in the chat window for these you pay a tuition fee for these first two and we target their professionals which already have a bachelor level and are proficient in English we also test that then there are MOOCs there's open course where open educational resources and webinars like that like these that are offered for free where MOOCs we could offer also a small fee for a certificate if you want a certificate so there are different open modalities available so we had a nice MOOC from AFRI Alliance I'll come back to that later we had webinars several ones like these here you see an example in cooperation with Australian Water School where we all were in different parts of the world and we have open educational resources such as my YouTube channel on GIS for example but what does open really mean well there's a clear definition of open that's also used for open source software or open data so here this the definition talks about data but you can imagine also other kind of resources a piece of data is open not only if everybody is free to use it but also reuse it and redistribute it and there can only be two restrictions to that that is to attribute to the source so if I put my materials as open courseware on the web then and you want to reuse it then you need to attribute you need to say that it comes from from Hans van der Krust from IHE Delft and another restriction you could put on that is share a like which means that everybody who derives things from this as also to put an open license on it and share it in the open way then there are several licenses you can put on your open courseware or on your courseware in general and these are the completely open licenses it's a very boring topic so I'm not going to spend too much time on this we call this also copy left as a contrast with copyright and I think it's very important that you know that these ones are the real open licenses but in general we use different ones also at IHE Delft we don't use the real open license but we use the Creative Commons non-commercial license CC by NC also this presentation is licensed CC by NC and this means that everybody in the world can use these materials for free but you're not allowed to make your own business out of that so that means that universities abroad are free to use my materials I don't have a problem it's always good to ask but if you are going to give paid courses commercially then yeah then we have a problem so it's very important that if you develop course materials that you license it in a proper way and that you know why you put a certain license on that and of course we want to spread knowledge but we don't want to build the business too much in for others without getting revenues ourselves so then we have the traditional course development at IHE where we start with our MSE module so the lecturers here develop lots of course materials for master modules that are taught here at IHE Delft face-to-face and then some of these courses become available as short courses that you can join here at IHE also and sometimes we get specific requests to make courses for customers that can be government or private sector there's also subsidies for example from NAFIC to do that and then we sell parts of those existing modules as tailor-made trainings that's the traditional way it has some disadvantages and the first disadvantage is that teaching materials are mostly developed with subsidies because our education part receives a lot of subsidy money and that part doesn't have many requirements to innovate so there's no drive to innovate I put it very black and white of course it's up to the lecturer to innovate or not but given the money that comes in for this there's no real drive to innovate also the scholarships that many of our participants receive are not really an incentive to be competitive with the market the self-players are more driving the the competitiveness and that's increasing with the years but the scholarships aren't really doing that and by packaging your modules also as short courses that externals can follow you break the learning curve because each time you get external participants and you need to start over again with teaching the basics unless you put a requirement there to follow prep courses we do have requirements to follow the courses but it's very hard to test it so there's a nice opportunity for e-learning to introduce their prep courses then we got into this era where we need to do everything online and we see it in the strategies but nobody really has a great vision on why should we do it so I call this spaghetti and this means that yeah well we start from our msc modules and we open parts online and we produce different online stuff and all these arrows can be connected in a random way but there's no real strategy behind this even not a business model which is very important if we want to do it so therefore this first question that I ask you why should we do this and that's very important so now for something completely different if you know Monty python this comes of course from Monty python what if we want to redesign our education based on this new insights of e-learning and using the the technology that is available these days then we need to really look at different things that we know so where does the money enter the system and that is when we sell our tailor-made advice and training so here in the liaison office our colleague Mita is coordinating our tailor-made training and advice where companies government anybody can request specific trainings from our experts and are willing to pay for that and it's based on the market needs by definition which means that it gives us a billable time and a budget to develop the course materials and in that way also is an opportunity to innovate and be the state of the art so we should really use that to innovate in our teaching then what can we learn from the corporate sector well very strange picture here that I took in the supermarket some decades ago we only had a one type of peanut butter in the Netherlands was just made of peanut and some oil and maybe some sugar was added it was a very simple product but nowadays you can see so many flavors and so many brands and as you know this is the era of caramel sea salt so there's even caramel sea salt double roasted peanut butter available so basically we can learn a few things we can sell the same peanut butter with different labels for a different price and we can add value to the peanut butter we can add some cheap ingredients and basically double the price so that has to do with an economic principle that we need to know the value chain of our products and services so what is the value we're going to add and we can ask money for and where does our market want to pay for it so that's very important then what can we learn from online services that are available because going online with e-learning is very similar to online products that we use here you see the example from Dropbox it's also like Google Google Drive you can get the basic stuff for free and if you get convinced and really want to use extra features then you're going to pay so I'm a happy paid customer of Dropbox and I get all these extra features and I pay quite a nice fee every year for that and I'm willing to pay because I know what I get for that and I got teased by the basic product so that's what you can do that's what we call a freemium business model so there's a value chain but you start with a free product that could be our open education materials and then what can we learn from the open source business model which you might know I'm quite active in the QGIS community which is a beautiful community to to work with and the main thing is that we don't compete with the product itself so the product has a very high value so the QGIS software but it doesn't have a monetary value for us because everybody who works around in this community does a job with it so you either sell your services for people who need help with QGIS or you sell courses or even if you sell if you have free courses in it there can be revenues from that I'll come to that with the value chain and there are companies who want improvements they want maybe plugins developed so you can agree that that goes them back to the to the community and it becomes available for every user of QGIS so in that way we can improve the software increase the amount of users and build this very nice community where you can also become a part of so basically this means and now I'm going to disappoint a lot of our educators here in the virtual room sorry your educational material is very valuable but doesn't have monetary value but what we do sell is the experience so this is the good news you are the added value because you provide the experience as a known or renowned expert and the way you teach is added value so basically that becomes our value chain I'm going to present a nice case study and it's a nice coincidence that today also national water of Uganda is visiting us and they were a basis of this case study because in 2015 I was developing a tailor-made training for national water in Uganda in cooperation with FITAN's AVIDAS International and we agreed with all the stakeholders to publish the materials as open courseware on our open courseware website of IHE and they all agreed with that and that was great because that was the starting point for me to record all the lectures and put it on a youtube channel and embedded in eCampus that's our online platform based on Moodle also open source and also to record all the exercises and publish it there and then it gained momentum and here we are celebrating today our seven years of the open courseware website if you haven't looked at it please take a look it's on ocw.un-ihc.org we can also post it in the chat and at the end we will have a nice surprise for you there are some new courses to be announced but there you will also find this nice course that had to start with national water I hope many alumni from national water are also here so what's the benefit of that I could reuse those course materials so the origin is the tailor-made training and I could use it then back in our master modules and nowadays I use it as blended learning so we maximize the time in class on the exercises for the alumni you know there's always not enough time for for GIS classes and of course I'm passionate about it so I want to to teach you everything and now we found a way of combining this so we do teaching the theory by the videos that people can find on eCampus and we do the practice in class we do quizzes with Kahoot and in that way we build up a very nice class and I also reuse these materials in short courses or even in tailor-made trainings because and that's my advice if you want to go this way is make your things modular so you can for different customers package the different modules and it resulted in a few new products so there's an online course which is on QGIS that's a joint venture with Newland Geo information it's a paid course so next to the open courseware but then as an added value that you can receive the official QGIS certificate and you get support and there's this nice book that Abram already mentioned QGIS for hydrological applications by Kurt Menke and myself and that's also the same course materials but then yeah compiled in a very nice book with the latest updates in it so I can recommend that nice thing for you to know is that when you buy the book my share of the book goes to a fund here hosted here at IHE to support participants from the global south to join me in QGIS hack fest and in phosphor G events because we have a lack of especially female from the global south in this open source community got some remarks on social media that are only men from Europe of my age on the pictures so I really want to make a change in that so if you buy the book you really can help with filling my fund and see some IHE participants joining this and spread the word of the open source community in the rest of the world this brings me to probably the most important slide of this webinar where we where I worked out the value chain and what we see here is on the x-axis we see the price of a product we don't really need to define that further it can also be the income for the institute or the tuition fee or whatever and on the y-axis we see the number of participants and of course with open courseware or MOOCs open educational resources the number of participants is very high this is relative and because everybody can follow it for for free so the price is zero then the next step is with similar materials we can produce a book where people just pay a fixed amount but they don't get support they don't get face-to-face experience and they don't get certificate now some people want support and a certificate so they can go for the online course we are developing now also a new online course on the same as as the book so completely for QGIS for hydrological applications where you can get support and this official certificate will be ready in a few months hopefully then some people want face-to-face training and IHE experience come to Delft and I know the alumni now get a bit of a warm feeling and we also want that many people can do that but it comes at a cost so much less people can do that and you need probably also scholarships to do that so therefore we offer our face-to-face short courses here at IHE Delft it's the same material but then face-to-face then we come at the tailor-made trainings where we can give specific parts of those materials to our target group but also develop more materials so there's again what I said before where the innovation comes in and you develop the new innovative materials and then we can use the same stuff in our MSC so all these materials feedback and that makes this model a bit circular to to the different products and again it all starts with innovation and being cutting edge I try to renew all my materials every few months that's not for every topic of course the case but it's important that we are not teaching 20 years the same material so this brings me then to the freemium model that I use then for my GIS classes so if you can see in this table is that in all the modalities open courseware online course short course and tailor-made trainings the course materials are available there's no change there's even in the free products you get that because it has no monetary value then with the online course and the short course you get a tutor for tailor-made trainings you can even choose for tailor-made online trainings which would be a great modality that we don't see much yet but it's increasing the official QGIS certificate you can get that with the online course or the short course and you can opt for it in the tailor-made trainings well etc you can read this table and you see how this works and of course the tailor-made trainings are very flexible so the impact of this business model was that I got a few new customers so many people know me from the open materials from the youtube channel from social media and this brings nice customers and I'm very happy that van Oort one of the biggest dredging companies in the world wanted QGIS training also nice to know that they use QGIS they were silver sponsor also in that time and they're sponsoring now the Dutch the first Dutch hackfest that we have for QGIS in this month in a week so I helped them to develop QGIS course materials which was more targeting offshore and was really nice for me to develop that together with them and for the food and agricultural organization we organized trainings together with E-Leave on crop mapping for the MENA region using QGIS of course and we see a big increase in short course participants and self-payers my personal target was to beat of course the non-open source GIS course of my colleague and I'm happy to say that we easily reached that target now these webinars should also not be underestimated we see now 94 participants on the screen and that's very nice I recently had one in cooperation with the Australian Water School which was a very nice opportunity we talked about QGIS for hydrological applications and yeah there after the webinar they produced this nice map with where the participants who registered come from of course much less joined but still I think we had about four to five hundred participants but we see we really covered almost the whole globe and that's your market potential and if you could have this widespread with our courses then yeah we really can increase our impact so also very important to monitor that I'll come to that later let's talk a little bit about challenges we need to be aware about intellectual property rights and clauses in contracts or letters of agreements I hashed out here some experience that I had here and which undermines our business model because if you want to do this business model that I explained you also need to get agreements with your donors and customers on what you can do with the materials and if I want to have the CC buy and see license but allow IHE ourselves to still commercialize the products then the text that is here on the screen does not help and in fact we cannot use it ourselves so in summary this text says that everything we made for this customer becomes property of the customer so you lose your intellectual property other challenges of course your organization your colleagues need to be aware of the business model of a viable business model and of course we can have in the strategy that we need to do more online but the colleagues will not move if they don't know why we do this and what the business model is so it's an incentive for your colleagues to make more e-learning if they know why and transition always needs flexibility of the organization very important you will bump into a lot of probably rules and regulations that are not promoting e-learning but go against it we know from some of our cooperation projects that a certain percentage in some universities can only be online so normally these procedures are a bit outdated and we need 21st century procedures and rules investments needed to be ahead of the market that's important so if you feel that customers can steal your intellectual property if you want to develop your course materials then you better develop it before the customer can do that so you sell the product that was already done I did that for for QGIS with with the materials around the app the input app and the merchant plugin it's a very nice tool which uses your QGIS project you can make an app that you can use in the field all for free open source and we were the first ones of course developing the materials there and you can find it on GIS opencoursware.org where all the GIS opencoursware from IHE is hosted and we hope of course that customers want trainings in that and then we can sell the experience instead of the product another challenge is we do not do enough monitoring in evaluation to measure the impact of e-learning and to confirm the business model so it's very important to have a good framework for that in place and I'm going to show you a little bit about that and what is worrying me a lot and I hope some donors will watch this webinar or later on the video is come on this is a great opportunity we need not only the orange knowledge program where many people here got scholarships from to have face-to-face trainings but we need a green knowledge program and with little money we can support a lot of people who want to learn things especially from the global south the most emails I got from my online course was that it was too expensive but the rates are very cheap for for Europe and for United States for example but I can imagine that for the global south that's very very difficult so probably using different tariffs but also providing scholarships and I think even individuals who want to support or adopt a e-learning student can just make a contribution there because that's not expensive let's have a look at the monitoring and evaluation so as said we are running our IHE open courseware now for seven years and here we see the statistics for where our customers come from and who use the open courseware so the free materials and most come from Asia and Africa so that's nice that's also very much representative for our face-to-face classes that we give but although it's accessible for the whole world we see most participants come from those places this comes from google analytics and well as a GIS person I had to modify a little bit the map because it uses the mercator projection which gives a bit of a bias towards the countries that are close to the north and the south pole and we don't want that of course then these are the statistics for the last year for this year the last 365 days and very nice to monitor that and to find out what the peaks mean thanks to our colleague Yipke from the Education Bureau we find here two peaks and this first peak was generated by the AFRI Alliance MOOC where many hopefully of you already participated in and there's a second peak here that was when I had the webinar with the Australian Water School and this generated of course a big load on our open courseware website and we hope that many people who join these webinars follow these online courses and open courseware and this is a proof that yeah it's also really a good marketing tool because you get interest in this another important 21st century skill is to use social media and e-learning is very adapted to that so you can easily link your open educational resources so open educational resources are small products like a little video of a few minutes or very short yeah materials that you want to put out there on the internet you can easily embed that in your social media tweets or put it on instagram and then you can attract a lot of potential clients and of course you hope in your business model that people will not only use the free stuff but also go to the paid products because they get added value like support and the diploma and we should also realize and we see a lot of in the discussions here with lectures that yeah we don't realize that we are now teaching to the millennials and these millennials are very different than previous generations they are used to watch short videos their tension line is much lower than the 45 minutes that we have in class so maximum five minutes which is very hard for lecturers but you have to cut it in pieces and they watch it on their phone while they're multitasking with netflix and other activities so yeah we really should fit to that lifestyle and offer our course materials in that format and it's a great opportunity for us to publish these short videos on social media on twitter and linked in and youtube even has community channels so so use that then what's in it for you as a lecturer well you get a lot of dopamine from that so I am enough motivated to make more videos if I'm not too busy with my my regular job because you get a lot of compliments on internet on your on your products so people call it here a lifesaver or the best material they've seen well that's of course what you want that's also what your employer wants to see and you can tweet about it and you see that many people yeah respond to those tweets or like it and we can get all the metrics also from twitter and that encourages us to even promote it more and yeah for this webinar I for the Australian water school I made this little video with an overview of our course offerings especially the open ones and yeah more than five and a half thousand people viewed this post on linked in that's that's also very helpful I want to come to conclusions before we go to the discussions what is very important if you are at the the moment thinking of developing e-learning is that you need to define your objectives so what is the impact you want to achieve so why do you want to do this what are your target groups what is the efficiency that you want to achieve etc things that we discussed you have to define the value chain of your course materials products and services what do you want to give for free what do you want to have paid customers for are they willing to pay and how do your colleagues look at that you need to internalize that and you have to develop the business model really take time for that because you can only get your organization so far if the business model makes sense that also means that you need to establish a monitoring and evaluation framework to see if it really works like you think it works there is in this presentation a lot of assumptions from my side and yeah we just have to measure these things and learn from you if it if it works like that then you need to do marketing also don't underestimate that you need to work on change management you will meet a lot of resistance maybe in your organization that things are not up to date your protocols are not up to date and you need to work on that together and again scholarships are needed so my great request to donors who are watching this or private people who have have money to support students we need a green knowledge program where we can support many more participants to to follow these classes even for diploma online now the surprise of the day is because we celebrate the seven years open courseware at ihc delft if you would go now to the website we have a few new courses that i want to announce today there is a new one on irrigation management and development there's a new one on delta planning and management and there's one on experimental methods which is in spanish there's an e-book and english is also available so i hope this will be very useful for you and i hope you will follow us and you'll see the new things that are posted all the time and if you have ideas then we also like to hear that from you so that's also the the last question maybe abraham can can put that up before we start the discussion is yeah what would you like to see as open courseware on our platform with this final question i would like to open the the floor for a discussion there were already some questions posted here and i give the floor to abraham maybe you can moderate this thank you for your attention thank you so much hans for that great presentation um we are going to pivot to um questions and i'll put up the first question online here on the interface here which we received by email from banmali who asks that one shortcoming of conventional educational material is language and for those of whom english is not the first language we struggle to benefit from books papers and lectures in english excuse me well this problem persists with open education or is there greater possibility of multilingual higher education with open education processes and tools yeah thank you for this very nice question maybe some of you know that i i'm also specialized in the francophone part of the world and have been doing there a lot of project work we always tried to to ask donors to and programs there to convert our english materials to french there seems not to be much interest for that from that side but we still have to put on the pressure there but in e-learning especially there's an opportunity because you can run these in parallel in multiple languages well face to face you are bound to uh yeah the majority of the group that you have in the in the class so we are working on it and maybe a nice other uh surprise for you is that we are working currently on translating the qjs materials to french with an alumnus of us he is in algeria now working on that together with me so that will become available so there's also a role that you can take up there to if you think that your target group is interested in another language of the materials we have a dopc2 program of developing e-learning materials together with our partners so you could write a proposal i'm coordinating that part so you can contact me and then i can explain you how we can proceed um i will next put up a comment by brian reid who says let me increase the font size to a more readable level one challenge is pedagogy teaching science books are fine for facts and face to face is good for developing critical thinking e-learning is is is much harder to use for deep learning says brian reid how would you respond to that um yes that is indeed a case where we have to carefully look at in the design of our e-learning um in my observation it's not always the case it depends on how you do the e-learning so with the qjs class of this year we used blended learning again and i used the book in class and i found contrary to the expectations that critical thinking was not improved because people expect when there's a lecture in the room that they get instructions and therefore i'm thinking of moving it to completely e-learning with only some contact hours where we try to work on the critical thinking so basically people figure out themselves with the tools that are available online like google and like other like papers they can read about the topic to figure out themselves how things work and then we have face to face sessions which are not about instructions but about discussion and helping each other out when there's problems with the course materials in the e-learning platforms themselves you can introduce quizzes and also the way of doing dealing with the assignments can be different so i would say yeah in gis you still have to submit a map and an explanation of what we can see on the map and a discussion maybe a report so the different ways of mixing e-learning with the traditional ways but and there's also teamwork is possible in e-learning platforms but i agree this is something of concern for the quality but not necessary that e-learning per se reduces that critical thinking the next question is from Jean-Marc it comes from twitter he asks if open education is equivalent to online what would open education processes that are not online look like interesting question i have not thought about that in my definitions and what i know it's always online because people can easily access that probably if you provide free materials on a on a dvd or as a free book a hard copy then it becomes also open education so yeah not sure what this meant here or what thoughts are about that we hope that Jean-Marc responds to us with a follow-up in course of our discussion we look forward to that question from Ujwal is excuse me i have a cough hands for your online course what is the mode of interaction with the tutor yes that's a good one there's two sides to that an online course the participant wants support probably 24 hours per day when to contact the lecturer to have help on the other hand from the lecturers side we need to budget these things we need to deal in the organization that that there's a time writing for that that i achieve we write time so how much do you allocate for your support so from the lecturers point of view you want to keep it to a minimum without disturbing the learning process of the lecture so what we do is set up frequently asked questions or forum forum on the platforms where people can read previously asked questions most of the questions i receive for qgis in the online learning are questions that are already asked i would say 99.9 percent so the answer can be easily copied from previous emails or other resources um there are modes of operation where you use a virtual classroom i personally have not yet experienced with that but i like that if i'm going more maybe with the ids students to the learning experience where they do more online where we can have some moments in virtual classrooms to discuss things there are probably more possibilities but this is what what i know of sima inga from zambia is working in the water sector in the area of hydropower planning and also in the energy sector as renewable energy co-coordinator so her the question is do you have a schedule of online lectures that are planned already so that i can share it with my colleagues in my organization yes i g delft has a page on our website if you go to education and then you will find online courses and under that you find a list um with all the descriptions and when they take place for my qgis course it's a bit different it's not in that list for some procedural reasons that we hope to solve soon but um that one also is different in the sense that it has a continuous subscription so anytime you want to subscribe you stay two months in the system but it doesn't have a fixed start and end period because i think it makes sense also to have these things more flexible for our users um the next question is from brannis law who asks if there are any courses or books on qgis implementation for freshwater biodiversity research that's an interesting map yeah not that i know of uh i i since i published my book i got in touch with some other lecturers from other institutions who also got a lot of ideas of thematic qgis recipe books uh you can understand that such a book on qgis for hydrological applications is a niche you of course are all people from the water sector but many people in the world are not so more generic qgis books like the book from kurt menke himself discovered qgis has a much wider use but i'm i'm sure that there is interest in thematic books so if you have a good proposal for that or need help then uh yeah i can always be available to co-author or review or help you with it so the next one hans is a compliment and uh you mentioned that something that keeps you going something that keeps you sort of motivated to keep uploading stuff on youtube is uh is feedback in compliments and from du du ba who says uh he's a student in environmental modeling at cz u uh thanks for dr hans's tutorials he was able to perform one of the most important tasks of his thesis which is catchment delineation for hydrological modeling yeah thank you uh du du for your for your remark i i know you already also through twitter and your questions there and you will be coming here soon for an internship so we can collaborate further so this is a nice example of people who know me from uh the open course where i use the tutorials interact through social media and uh yeah then end up at ihc doing an internship for uh yeah learning more the next uh comment is from maria who says most online seminars are advertising for a specific project without critical pro and contra knowledge exchange often no neutral overview of different methods of practices as shown how can more knowledge exchange be promoted yeah that's a good one i uh i agree with you that this should be done more so online seminars should be a two way so always should include this part where we have uh question and discussion in in this format we uh we have half an hour for that i think that's a very decent and most often it's not the case uh so that should be always a part of it i think there should always be some uh some questions like we also did today where we interact with the audience uh during online seminars and webinars there's limited limited time for that but if you have more online courses with these virtual classrooms you can have more knowledge exchange you should also do more peer learning i also hope to learn from the participants of these webinars to get new ideas there are already some questions that i have never thought of that were ever asked so there's definitely space for that but we need to provide that space and be conscious about it uh the next question is a very specific one it's from Rehoboody who asks if there are any webinars around on pc raster i don't know if i pronounced that right yeah pc raster that's a that's a good one um today a new version of pc raster came out for 4.3.0 and i was immediately thinking if i wouldn't have had this webinar today i would have a new video on how to install it um webinars on that there is also a person who was here for an internship in summer and was working on with pc raster on the thesis and yesterday told me let's make a webinar on this so it will come uh we are working out the details so uh they will be there for sure i'm increasing also the video content on pc raster on my youtube channel so i'll keep you posted uh the next question is from Khalid i'll just increase the phone size of it so we can all read it Khalid asks Khalid is from the UAE national water center and he has a question about using satellite data and processing this data such as grace and grace fo it seems a lot of research recently focuses on using grace do you think there will be courses explaining the interactive use between grace and qgis well it's a it's a question of demand and supply here for economic principle so if you would look at questions asked in my youtube channel for example you will see that many people proposed to me to make courses on topics but yeah i also have a job and a life next to my youtube channel so we cannot offer all these things that are demanded and if you see the value chain curve that i showed you before it all starts with where the resources enter the system so if there is enough demand and then i can make it if it's a hobby and if i really feel like i can do that then i would do it myself so basically requests for certain things that's also in the open source world in general that's your least chance that these things happen your higher chances to engage start the project look for resources to gather and cooperate and then we can make this okay okay i think that that we have reached the end of the excuse me again we have reached the end of the questions and comments thanks a lot hans for your great presentation and thanks to all of you for joining in for and for your great questions and comments first of all thanks hans for pointing out that i made the mistake of using the terms open education and open source education interchangeably i understand now that open source pertains to code and we should be careful about which term to use where open source open data and open education i will not attempt to summarize the discussion here in real time but i would like to share with you that my takeaway is that the education sector or to put it more plainly the process of teaching and learning is set to change in profound ways in the coming years and it is great that some of the leading educational organizations such as it apart from several others do recognize this and are spearheading this change they're trying to be part of this change rather than resisting it and i think that's very important that institutions are doing it apart from highly motivated individuals such as hans and so thanks a lot this is perhaps a good point to mention that the next webinar will be on the topic of desalination and will take place in april or july and after that there'll also be a webinar in may so please follow the following links i will just put them up in the chat box to stay updated as the topics the speakers and the timings are finalized so and also on these links you will find a recording of the webinar from today this webinar it should be up at some point tomorrow at the latest and yeah thank you all for joining in thanks hans again thank you abram and also thanks to the whole team that made this possible including maria who invited all the alumni and jipka and rakel from the education bureau and wim glas for facilitation here thank you very much for the opportunity bye


growth is just thousands of stuff that you wouldn't even want to be called calling growth. Some of those thousands of steps are backwards. Who wants to talk about that? I grew so much this last year. I failed so much this last year. It was amazing. Who tells? Who says that? Some of your growth is your worst days that you've thrown away and thought, God help me. What? Hang on a minute. Go back and collect something that belongs to you in that. Don't move on before you went and took a seed from that sorrow that's for someone else that needs to figure something out. Thousands of small steps.


From Austin, Texas, it's theCUBE, covering Pure Storage Accelerate 2019, brought to you by Pure Storage. Welcome back to theCUBE, the leader in live tech coverage. I'm Lisa Martin with Dave Vellante. We've got a pretty cool guest coming up next, guys. You may have seen him here on theCUBE before. He is back, Matt Harris, the head of IT for Mercedes AMG Petronas Motorsport. Matt, welcome back. Good afternoon, how are you? Good, we got the car over there, lots of excitement. One of the coolest sports I've ever become involved with, Formula One is this incredible mix of technology, strategy, all these crazy things. You guys at Mercedes have been partners, customers of Pure for about, what, four or five years now? 2015 as a customer, and we became partners in 2016. I wonder if they like to say Mercedes AMG Petronas Motorsport has had five consecutive years of both constructors championships, drivers championships. You're at a great position on both for 2019. Give us a little bit of a history about the product that you put out on track every other week and how Pure Storage is a facilitator of that. Yeah, okay, so it's an interesting story for those that are interested in Formula One, because what you see on the track looks the same, but realistically, every time it goes out the garage, it'll be different. That level of difference could be a simple wing change or configuration, always based on data that we're learning from during a race weekend. But every week, we also have a different car dependent on the track we're going to. So we have two different worlds that are basically we iterate on a minute by minute, hour by hour, and day by day at the track. But in the factory, that could be the same sort of iteration, but it could also be into weekly or monthly or year for a car. So all of that is based on data. So everything we do as a business is revolves around data. We never make a change to the car without being able to back it up with empirical knowledge. Even if the driver turns around and tells us they feel something called they believe something, we will always make sure we have data to back up that decision. So access to data is critical. Compute performance, whether it's high performance compute for our CFD, for instance, whether it's for you as an end user, access to data is critical across everything that we do. It's time critical. Time is our currency really as a business. If we slow down your job, generally that probably means that you've got less time to make the correct decision, or maybe you have to turn it into a guess or a hunch, which that's never a good place to be in our sport. No, I would thank God. If I recall from our conversation last year, there are rules that say how many people you can have in your entourage, like 60 I think it was, right? Yes. And at the time I think you said you got like 15 allocated to data. Is that ratio kind of still holding? Still exactly the same in our track side environment, that's still the same. In the factory, we have more than that. Depending on how many people and what time of day and what day of the week. So on a Friday, a practice day, we can have a minimum, there'll be 30 people in our race support room. We'll be looking at data along with those other 15. But you can have the whole aero department or design department or logistics, whoever can still be looking at data from the track real time. So we can have as many as 4 to 500 looking at data if they want to and if it's the right thing going on. Earlier in the season, you generally get more people looking as the season goes on. It's probably more aero focused, maybe mechanically if we've got something new or maybe the engine division. Again, in a completely separate building in the UK, 40 miles apart, they've got another set of people that will be looking and trawling through data real time from the, but looking really at the power unit rather than the chassis side.  Is that still about the same or is that growing? From a car perspective, it's just under half a terabyte, but we produce up to another half a terabyte of other supporting data, whether that GPS data, weather data, video, audio, whatever it would be, other information to help with the strategy side of things. So we're around seven, I would have said 750 to one terabyte per race weekend. And each car has about 300 sensors. I think when we spoke with you last year, or maybe a year and a half ago, it was about 200. So that's increasing in terms of all of the data being captured every race weekend. But one of the things that Madda says is, you know, where IT at Mercedes is not that unlike IT at other groups who really rely on high performance systems, but you do put out a new product every two weeks and this really extreme range of conditions, your product is extremely expensive and it's pretty sexy. But the portability factor, you have to set up IT shop, how many, 20 weekends a year, and set it up in what, 36 hours and take it down in six? Yeah, and I always joke about the taking it down in six is a bit like a Benny Hill sketch. It's obviously choreographed and well rehearsed, but we have all the same systems as any normal business would have. The track side environment is very different though. We don't have air conditioning, so all the IT equipment has to work at the natural ambient air temperature of the country we're in. This year, believe it or not, Germany and Hungary have been our biggest challenge we've had for the last probably three to four years, because they had 45 degree ambient air temperature. So forget humidity for a minute, which is another kettle of fish probably affects us a bit more maybe than the systems. But we're only chucking that air as fast as we can across the components. So we're not putting any cooling into what is probably around the tolerance of most IT systems. So we had to rely basically on air throughput to turn around and keep it cool. Now the benefit with Pure is actually it doesn't create any heat either. There's no real heat generation. So it's quite tolerant, which helps us because it doesn't create more. But the environment we put it into is quite special. But what we're doing is what any business would want to do, access to email, file systems, what we're trying to do is give it in a performance fashion. People need to make a decision. So in qualify, in for instance, those 300 sensors, that information that we've got from the car, we've got minutes to make a decision based on data. If it takes you too long to get the data off, you can't then look at the data to make a decision. So we have to make sure data ingest from the car and then basically multi-access from everybody in the factory or the track side is performant enough to make a decision before the car goes back out again. Otherwise, we're wasting track time. So you've always had data in this business, like early days was all analog, and it obviously progressed. In thinking about what you want to do going forward with data, what kind of information or capabilities don't you have that technology in the future could address? Yeah, so interesting one is technology in the future. If you know what it is, let me know. But with what we know right now, I think a lot of it's going to be about having the ability to have persistent storage, but actually the dynamic of the compute resource. So looking at things like Kubernetes or anything like that to turn around and have dynamic resource spin up as and when required to do high performance compute calculations based on the data, maybe to start giving us some automated information. I'm going to be careful with the ML AI. It's for our business. It's not quite as simple as others because our senior management are very technically capable and they just see it as advanced statistical analysis. So unless you program it, it's not going to give you an answer. Now, we've started to see some things this year where actually the computer is teaching us things we didn't ask it to. So we have got some areas where we're beginning to learn that that's not necessarily the case now, but for us, that access to data moving forward, it's probably going to be the compute combined with that underlying storage platform that's going to be critical. On stage you heard Rob and people talking about the ability to have that always present storage layer with the right compute. That's something for us is going to be critical because otherwise we're going to waste money and have resource sat doing nothing. Is security an issue for you? I mean, it's an issue for everybody, but is it a game of honor?  So it's an interesting one inside the sport, actually no because a few years ago there was a very high profile case where data went between two teams and there was 100 million pound fines exclusion from the sport for a season. So that's too big. You don't mess with that, right? But also if you think of that from our perspective, we've got the Daimler star on here. We cannot afford to have any of that brand reputational rubbing off on Daimler. So that's a no-no. Other teams I can't talk for, but we're all fairly sensible between ourselves. What will be interesting moving forward is what technologies are in our sport that actually other, whether they're motor manufacturers or not is their technology in there that they're interested in? Maybe the battery technology from the power unit side of things. Is it the power unit itself? Are other things actually more interesting to those other places? Is it legal for you, by the rules of the sport, to monitor just data or capture data, whether it's visual or whatever, from your competitors? Yeah, so anything that's public is fair game. Okay. So we get given all the teams actually, we get a standard set of three or four different streams of information around GPS timing and some video feeds and audio feeds and they're publicly consumable by the teams when I say public for a second. And those feeds, we can do what we like with. You know, they're there for us to infer information, which we do a lot of, is what helps our strategy team to turn around and actually predict what we might or might not need to do as far as a pit stop or tire degradation. And that's where the human element must come in too, understanding the competition, like two football coaches who know each other, right? Well, yes. And now if you think, if you add to that, the human element of, well, what happens if one team's strategy person changes? Are they going to make a different call based on the same data? Is their hunch different? Do they think they know better? Yeah, within a team, you can have that discussion. So what happens in another team where their car's not as performance or their mindset maybe they're thinking differently? Or maybe a team's got the most performant car at the moment and they think that they're going to do X and we're like, well, we're going to do something different then to try and actually catch them out. So do we now do the normal thing? So let's look at- Great gamification, I love it. Exactly. Let's look at, I'll make a prediction. 2019 is going to be another Mercedes-AMG Petrinus Motorsport year. Shhh. Not good, there you go. Not good, there we go. So at the end of the season, all of the data that you have collected from the cars, all the sensors, all the weather data, GPS, et cetera, how does peer facilitate in the off season the design of the 2020 car, for example? Where does it play in things like computational fluid dynamics? Yeah, okay, so all of our production data is on pure. Whether it's on a rail or blade somewhere, it's on pure storage across the site. So they're involved whether you're talking about design, whether you're talking about finite element analysis for high performance, or the CFD, using high performance compute systems, everything's on pure. So from that point of view, it's making sure we're using the right resource in the right place to get the best performance. Now, CFD's an interesting one, because we're regulated by the FIA about the amount of compute that we can use. Now, because of that, you want it to be as efficient as you possibly can. It's not speed, but the efficient use of CPU time. So if a CPU is waiting for data, that's wasted, okay? So for us, it's trying to make sure that whole ecosystem is as efficient as we can. That's obviously an integral part of everything we do. So whether we're wind tunnel testing, whether we're in the dyno, the simulators, but everything basically comes back to trying to understand and correlate the six or seven different places we generate data, trying to make sure that when there's a change in the simulator, we understand that change in the real world or in a dyno or in CFD. So all of that, what pure do is allow us to have that single place to go and look, high performance, always available. And for me, I don't have to have a storage admin. You know, we've got a team of people that actually are thinking about that for us at Pure. You know, they're as invested in us these days. You know, I walk around here, I'm very fortunate. I get to see all of the senior guys here and they're asking me what's going on and house things with SQL or Oracle because they know exactly what we're doing and they're trying to say what's coming. So things like object engine and PSO, we've been talking to Pure about using that over the coming months, but what we're not having to do at the moment is go out and learn it. Actually, they're coming in and they're telling us all about it. So they become a virtual extension to my team, which is just amazing. Yeah, far more efficient. You're able to focus on a much more things that drive value for the business. As we look at some of the things like the Evergreen business model, what were some of the big, aha, Pure is the right solution for us back in 2015? Was that part of it? So Evergreen and Love Your Storage were two things at the time that were just incredible for us. Because Love Your Storage was basically, you could have an array and basically you could use it and there was no commitment, no anything, but if you liked it, you could keep it, obviously paying for it. And when we did that in the factory, basically within a week I've been in there, the team were like, whoa, hang on, that's going nowhere. So that was a nice, easy one. But Evergreen was an interesting one, which has only really, truly for me, I've always bought into it, but the last probably 18 months, we've used it time and time and time again because the improvements with the speed of X90 coming in, VME drives, when we were looking at capacity, what we did was we turned around and said, well, actually we can buy more dense units in an X90. So we're only buying the extra capacity but we were getting new technology. Right, innovations. All that innovation that Pure are putting into their products, we're getting it. So today when they were talking about the memory-based access and a few other things, I was sat there going, oh, I can use that. Oh, and there's no work for me either, there's no effort. The only thing I've got to worry about is whether I've got capacity for those modules to go in. So Evergreen has worked several times because I don't have to go back to the CAP export and go, can I have another X million pounds please? Why? I need some more storage. Yeah, but you bought some the other day. Yeah, well, that one, I'd need to get rid of it because I need a bigger one. And I don't have to do that now. I just go and I'm telling them what the increase is for, which actually they can choose then if they want the increase. They know what the business benefit is rather than just IT has got to turn around and either replace it because of age or the new version doesn't support, it's not an upgrade from the old one. I was looking at some of your stats in the case study that's currently online and I imagine these numbers have gone up. It's 68% reduction in data center rack space and saving 100,000 pounds a year in operating costs. Yeah, that would have been probably two years ago-ish roughly those figures. And the operating cost is a huge improvement for us. CAPEX is probably the biggest one for me though and moving forward with cost caps coming into Formula One, that type of thing is going to be invaluable because not having to do a forklift upgrade of your storage. Well, I wouldn't know what I would do if I had to upgrade what I'd now own from Pure. I can't even imagine what, I don't want to turn around and tell my bosses what that's going to cost. Well, it sounds like you really attacked the OPEX side with R&D, with Pure R&D. I kind of like that, shifting labor to R&D because you don't want to spend labor on managing storage arrays. It makes no sense for your business. Okay, what do you want Pure to spend R&D on now? What problem can they solve for you? Where's the pain? So, Array C is going to help, if I'm really honest. That actually is going to help fill a hole quite well for us because we weren't really sure what to put some of that less hot data. And we were like, well, where are we going to start to put this now? Because we were beginning to fill up the array and the blades. But actually with Array C now, we can actually use that different class of storage actually to keep it still online, still be able to do some machine learning AI in the future when that comes around. But actually I can now have more longevity out of my existing array and blades. So that's brilliant and coming. I think having, I need to be careful because I know some things that are coming. The active sync in Array is brilliant and we've been using that since it came out. Having that similar or same ability in blade when it comes will be very advantageous. Yeah, having those blade enclosures, we've gone to multi chassis flash blade over the last six weeks. So that for us is great. Once we can start to synchronize between those two then that's another big one for us for resiliency, for fault tolerance, but also workload movement. That thing I said about a persistent storage layer, I'm not going to need to care where it is and it will be worked out by the storage and that orchestration layer. So it can have the storage and the compute in the right place. Wow, great story Matt as always. And I think as Pierre calls this the unfair advantage coming to life best of luck for the rest of the 2019 season. I'll take it. Thank you. All right, we'll see you next time. Thank you for it. For Dave Vellante, I'm Lisa Martin. You're watching theCUBE from Pure Accelerate in Austin, Texas.


Hi, Psych2Goers, and welcome back to another video. Have you ever been betrayed? Did you see it coming? If not, do you ever wish you could have known beforehand if someone was going to betray you? As much as you want to give people the benefit of the doubt, being betrayed is more common than you would like to think. Between romantic and platonic relationships, have you ever felt like betrayal is unavoidable? While you can't control how other people act, did you know that there are always ways to tell when someone is going to betray you? They're subtle and easy to miss if you don't know what to look for, so here are nine signs someone is about to betray you. Number one, they're only there when it's convenient for them. Have you ever had a friend that was only there whenever there was something they wanted? They're there for you when you're having fun, but the second you need their comfort and support, they're suddenly busy. While it's hard to accept, people who do this generally don't care about you or your feelings. They're not real friends, meaning they're likely to betray you when there's nothing else to gain. Yikes. When you notice someone doing this to you, you may want to reconsider your friendship and find some friends who truly care. Number two, they've begun to act out of character. Have you ever thought you knew someone, only to see them start doing things you never expected? For example, your shy and reserved friend suddenly begins to hang out with a more popular friend group, so their behavior and mannerisms transform completely. While people change every day, sudden and drastic changes could mean that they have reinvented themselves and aren't the same person they once were. They could be more inclined to betray you as part of their new persona. Watch out. Number three, they've begun to distance themselves from you. Have you ever noticed anyone pulling away from you? It could be making up excuses to avoid you or unfollowing you on social media even. While there could be other reasons for this, it's a big sign they're preparing to betray you. Putting distance between you two generally means they're becoming less emotionally invested in you, meaning they could be pulling away to avoid the guilt of betraying you afterwards. How nice of them. Number four, they begin to give you underhanded, insincere compliments. Has anyone ever said the following to you? You actually look nice today. Or I would have never expected it, but you did surprisingly well. Wait, what? While they may sound like compliments, if you look a little deeper, they're underhanded jabs. People often speak this way when they're jealous of you and want to bring you down without being obvious about it. If you've noticed someone doing this, it's likely they don't really like you and are more inclined to betray you.  Have you ever accidentally heard someone gossiping about you? Was it a friend who gossips about others to you? But you never thought they'd treat you the same way.  It's not only a big indicator of a fake friend, but it's a sign someone is capable of and likely to betray you. On guard. Number six, they tell many small lies.  Whoa, pants on fire.  If someone is lying about minor things like where they got something or who they talked to, they may have the capability to lie about bigger things. A genuine person wouldn't lie even about small things because trust and communication are key factors in any relationship. Number seven, they dodge your questions. Has anyone ever answered your questions with fine or another question? Much like telling small lies, it may not seem like a huge issue, but it's a big sign they're not trustworthy and have something to hide. Avoiding your questions generally means someone is preparing to or already has betrayed you. Number eight, they conceal their phone from you. Okay, picture this.  If they're hiding their phone from you, they probably have a reason why. It's a secretive and distrusting habit, meaning it's probably a good sign they'll betray you and your trust and your confidence. And number nine, they change account passwords that you know. Talk about foreshadowing. Has anyone ever removed your fingerprint from their phone without telling you? It's a big indicator they no longer trust you and are pulling away from you. There's also probably a reason why they don't want you to have access to their accounts anymore, which hints that there's something they're hiding. If someone you know has recently begun to hide their information, they could be preparing to betray you. The most important thing to remember about betrayal is that it isn't your fault. You can't control how others act, so all you can do is try to avoid such people who betray others. It can take months or even years to get over. But with a little timely vigilance, you can help protect yourself from its lethal clutches. Keeping an eye out for these signs can surely help you spot betrayal coming from a mile away and take measures to tackle it. We hope we were able to give you insight into some of the telltale signs of impending betrayal creeping towards you. Do you think these nine signs will help you do that? Have you ever encountered these in real life? Leave a comment down below about your encounters with them if you'd like. Please feel free to share any thoughts you have as well.

Your role models, not only for other young entrepreneurs but more importantly also for businesses like ourselves as well. We frankly could not address in our business model many of these societal issues if we don't link in firmly with the creativity and the passion and the strong purpose driven models that you have created. You're therefore role models for many people beyond what you can imagine yourselves.


So my name is Rich Meggison. I'm the tech lead for the Linux System Roles project, and I'm here today to talk to you about how you can use Linux System Roles to manage standard operating environments. So the problem I want to talk about is, how do you manage a lab which has a diverse mix of machines and frequently changing requirements? So I need to manage and enforce a standard operating environment across all of my machines. I need to be able to keep up to date with security requirements and industry best practices, and I need to automate as much of this as possible. In case you're not familiar with Ansible, it's a tool for automating software management using an SSH-based protocol and simple YAML file configuration. It has a large library of support for many different software and devices, and supports a wide variety of platforms. Linux System Roles are a set of Ansible Roles used to manage operating system components. They provide a consistent interface to those components on different platforms and OS versions. They abstract the configuration interface from the implementation. So for example, the network role can be used to manage network settings for both the init scripts method and the network manager method. Similarly for the time sync role, it can be used to manage both NTP and crony. In most cases, the maintainers of the packages in Fedora and REL and in some cases, the upstream maintainers of those components, also contribute to the roles. So that way we can keep the role in sync with the actual component that it's being used for. Some of our roles are supported on REL6 and REL7. Some are not. For example, the session recording or T-LOG role is new for REL8. So we don't have support for that on REL6 or REL7. Also all roles work with a REL7 controller. So that would be an older version of Ansible like Ansible 2.8 and Gingya 2.7. So this is important if you have a dedicated Ansible controller node that you can't easily upgrade. You can use that node to deploy all of our roles. We also have a collection in Ansible Galaxy. It's under the Fedora namespace. It's called linux underscore system underscore roles. So by now we have quite a few roles that we have developed. We have some ones that have just come out such as SSH, VPN, SSHD, and crypto policies. In addition to these new roles, some of the existing roles have several new features such as the storage role now supports Lux encryption, the network role supports wireless and DNS options, and there's many, many more. And then also have listed some of the new roles we have planned in the pipeline. So these are the components used for managing my standard operating environment. Ansible provides the automation framework. System roles allows us to provide a consistent software management interface for a wide variety of system components across a diverse mix of platforms. The use of relatively static playbooks provides consistency in how the settings are applied. So once I get my playbooks debugged and working the way I want and I don't have to change them, then I don't have to worry about testing them. You know, I don't have to change them and then worry if I broke something. If I don't change it, I don't have to test it. So the use of the dynamic inventory allows me to add, remove host, update host groups and keep my settings up to date. And then if I keep my inventory and playbooks in Git, I can use a GitHub style workflow to redeploy when something has changed. So here we have an example of an Ansible play that applies several roles to all machines. This is my baseline common SOE configuration. So I have common settings that I want to apply to all my machines, kernel settings, security settings, time sink, kernel dump, and many more. In addition, I'm using the T-LOG role to report all login sessions to my lab machines. And I'm using the VPN role to ensure that all traffic is encrypted between my lab machines in case some services cannot use TLS. And then I'm using the network role to create a bonded link for a management plane or a backplane. One thing to notice here is that order matters. So we must do these lower level settings such as kernel settings and crypto policies first. And in some cases, they may actually have to reboot the machines in order to be applied before I can move on to what I'll call the higher level settings. So here's an example of my main inventory file. So this defines the host, the host groups, and some host and group specific settings. So for example, settings that would need a host name or a list of host names. But all of my other config is in group vars files. This inventory file I might keep and get, but I can also dynamically generate it. So this is my all.yaml. This is where I keep my common baseline configuration that I apply to all nodes. My kernel settings, crypto settings, time sync, SSHD, and lots more. So I can then add or override these with group specific settings in group vars files. So typically I would keep this and get and I would probably have to update this frequency frequently as new policies and new requirements require. So some of my machines are clients and some of my machines are servers. So these are plays that I would use for dedicated clients. The host notation means all hosts that are not in the logging servers group are my logging clients, for example. So I don't have a separate group vars inventory files for these. These settings are also in the all.yaml file. So here's some plays that do the additional management required for nodes in the dedicated server groups. So note that some system roles can manage both client and server hosts, such as the logging and metrics roles. But some roles are dedicated to one or the other. So we have a separate NBDE client and separate NBDE server role. And so here are the settings which are applied to the nodes in the logging servers group. This is in the logging servers.yaml group vars file. This configures the logging servers to ingest logs from the test lab machines and it stores those logs in local directories, one directory per host. So I could also use this to forward to some external log aggregator if I wanted. And then the same applies to metric servers and NFS servers. I have a group vars files for each one of those. All right, it's time for the demo. So I have a prerecorded demo. It's just going to use the collection. So I'm using our Linux system roles collection. I'm also using the Oasis roles collection for Man'sville Galaxy. I'm going to deploy three hosts. One of which is a server and two of which are clients. And I'm going to apply my SOE to all of them. And then I'm going to log in and check and make sure my settings are working. Setting up a standard operating environment using Ansible. This is the playbook that I'm using. Baseline setup, logging servers, metric servers. It's set up for, I have a main file. Before I define my hosts variables that depend on host settings. So now let's take a look at the group vars, my baseline, kernel settings, crypto policy, firewall, time sync. This is also where I have my client settings too. So you can see I have NFS client settings in here. I have my logging client settings in here. As you can see, I'm using the rel client. Look at the logging servers. So this is where I have my settings for my logging server. So I'm just logs from coming in from all the clients. And then I write them out to a logged or NFS server. So I have my storage volumes that I'm using on my NFS servers, server settings. I can see if our settings were applied. So let's take one of the servers. Well, the logging metrics and NFS server are all the same hosts here. So let's just find the IP address of that host and let's log into that server. First thing you see is that session recording is working. The session is being recorded. There's some various things here. Check and see if our NFS exports are working. So export FS reports the data volume that's being shared. Let's check our exports file. That looks correct. There's the data volume. Let's check our VPN IPsec traffic. You can see we have a log in this directory. We have subdirectories for each host client that we're gonna see what the logs look like from one of our clients. You can see there are a lot of logs here. Sub D service. Server settings were applied. We should have a sub directory here for each one of the clients. Create a file in the NFS shared directory. The next thing we'll do is we'll log into a client and we'll see if we can see that file from the client. So there it is. So we'll log out here. Let's look at our inventory again. Session here is also being recorded. NFS share and there's the file that we created on the server. We can DF output. We can see that the slash data directory is being NFS mounted from our server machine. Let's check the IPsec VPN traffic here. So we can see that to the server machine there is a lot of traffic in and out. So we're not doing anything directly. We can create a file there and then see if we can see it on the NFS server. Let's log back into the server machine. Let's see if our network settings were applied. So we were going to create a bridge. There's our two ethernet devices. There's our bridge and our bond. Okay. Demo is done. So here's some links to documentation and references. So there's our landing page. Here's our Ansible Galaxy page for our collection. And there's some other information and I'll have the links to this demo posted pretty soon with the other links to the other demos. Please provide us feedback. We'd love to hear what you have to say. There's a link to our IRC, our email. You can file issues at that link on our GitHub landing page or you can file issues and pull requests. Each role has an individual repo under our GitHub organization. You can file issues there as well and let us know. All right. Thank you very much. Thank you for your talk. We have some questions here. So if you could please go to them. Okay. Sure. That's under Q and A. Oh, okay. Do you remember how much time it took for the playbook and the demo to execute? I think it takes about, I wanna say about 10 minutes. Give or take. Let's see. Is the demo session code available on GitHub? Yes, it's available under rich M on GitHub under my rich M. User account. It's called devcom 2021. I need to clean it up a little bit and then I'll publish it under the Linux system roles landing page somewhere where we have our other demos.
