All right, do it. Oh my goodness! Krillin wants to be a Pride Trooper, dude. He's been here for too long. How's it going, everybody? Dodged away here back with some more Dragon Ball Fighter's rank matches, and today we are finally going to be trying to get into the rank of Pride Trooper. We're still a couple of thousand points away, and we're not the same rank as our opponents, so it might take a few matches, even if we do win all of them. But first, we got to win. Oh, and it doesn't look good. Wow, those were keyblasts? All right, maybe next time, Chousy. All right, I'm just a dude. I've really just been zoning out and playing Fighters for like the entire day. So I am more than warmed up. I, in fact, my hands are tired. Do I want to do this? Let's try this. I think that might miss. That would be good. We don't have... Oh, he went out. All right, take throw. Yep, we got to get your number back in. 6M. Nice. 6M actually does land, so that is going to be Genemba out of the game. Hopefully, meterless. Ah, it's not meterless, and I didn't stop. Dude, just because I should have went for the kill. I got to, I got to stop trying to save bar. That was happening during like the games I was playing earlier too. Just so many times, I was like, can I do this meterless? And then I'm like, oh, well, I immediately regret that. Please hit. Nice. All right, let's just get Genemba back in. Super Dash. Super Dash. Make sure we don't mess up the timing. If we hit, I probably just would have gone out into Yamcha or something like that. Maybe a knee drop. Oh, don't lag. Don't lag. We need this to be clean. Hey, Yamcha. Hey, my man. Let's go. No way to kill though, so we're just going to wait. Maybe, hold on. I probably, I might have been able to kill. I don't think this will. That would have been wild. That would have been wild if that killed. But yeah, this team really does a lot of damage with their supers. The destructive disc and the tri-beam combo. That's the, that's the sweet spot. Oh, Super Dash. Hold on. Hold on. We got to close closing these games.  I can admit, I can admit some faults. No, why would you think I want Super Dash? Just because I put the input in. The game should restrict me from sparking in situations like that. I did not mean to do all these, these sausage fingers, dude. How am I supposed to play fighting games with this? I'm, I'm sick. I'm sick. I'm panicking and I'm sick. At least he's, at least he sparks so we can maybe try to hold out the hope and maybe get into a 1v1 limit break situation. Oh my God, he's going crazy. Vanish. Oh, get him. Get him. Okay. Slow it down. Make sure we're taking our time. Kill that sparking blast. It's not going, I'm not, I'm not going slow enough. I can talk as slow as I want the games progressing. All right. Catch this to him. Don't block. Just catch this to him. All right. We're good. Oh, we're not good.   Level three. Hopefully he uses that some other way than a knockdown. Oh, there's the knockdown.  Let me get out of here.  I don't want to be here just as much as you don't want me here. I'm, no, please stop lacking. Oh, no. All right. Hold on. Hold on. It's over. I've mentally cracked. That's just an audible mix of them. I'm not, I'm not giving up. Let's go. You think just cause you got the neutral over me. How did I block that? Let's go. Half a bar. That's still not going to kill. Damn. Oh, even the change couldn't help me there. All right, but we got him down to low health. Did we just play neutral? Oh, let's go. Oh, let's go. I could tell him the clutch after, after he got hit by that 2L. I knew he was, I knew he was cracking too. So I had to go for the risky overhead. All right. Oh, only a thousand points. We have to win like five straight. All right, strap in boys. This is going to be an intense video. This is going to get intense. If that was the first game, I don't want to see the second, but I have to. That's the crazy part. Oh, just stab me like that.  Man, I could think of a million other things that would be less stressful right now. Come on, Krillin. Come on, Krillin. I know you got stubby arms, but you got to, you got to get some, some range. All right. Janem is down again. I didn't have, didn't not too many worrisome moments with that. Just the one time that he, ah, the EX legs. I got to be more careful in that range because this is damage. Why? Why'd they give you on that? Okay. Maybe I could, he's really super dashed like that. I got it. I tried to do the downwards keep. No, not Vegeta. We already know this character does bad. There we go. There we go. All right.  All right. All right. Level three. I'm just going to do it. Maybe switching out Krillin would have been a little bit. Oh, big lag. Maybe switching out Krillin would have been a little bit smarter, but you know, at this point, I got to start thinking about characters after Krillin. Ah, there's the EX legs. Anything he hits me with would have killed me, but he drops it entirely. And there's the normal legs. To be, I was running up into him. I wasn't thinking very strategically. He still has that sparking. He's saving it. Tickthroat. Nice. Another one lands. We got to start making him question that. I want to try to start getting in this, uh, stagger offense. Chow Tzu on a wake up. Still not. I don't think he's fallen for the staggers just yet. We need like one or two more tick throws. One or two should get him down. Overhead. So slow on defense. I think we should probably go for a level two spark. I think that might be the move. That might be the wave. I'm afraid he's gonna DP. He couldn't kill from that range anyway. All right. So we'll pop it here.  All right. I think am I going to do this? Am I really about to do this? Please? Is that going to kill? One, two. All right. All right. That's fine. That's fine. We did spark, which means Yanchun won't get to level three. But if we just, if we hurry up the tempo, hopefully we can finish this before. Yes. That's exactly what I'm talking about with the tempo. This isn't going to kill. Maybe wait. Tien kind of hurts where it's sparking still. Oh, no. Oh, get off of me. No, Tien, you know what? Take it, Tien. Die. Let's reset neutral, baby. Sorry, Tien. I know you did a great job. I just, you know, sometimes neutral.   I can't block. All right. We're good. All right. We got the super dash. Oh, all right. How many more games? Just tell me how many more games, Arxis, and I'll try to win as many games as I can. Oh, we need like, I don't know, two more at this rate. Oh, thank you. I thought I was going to get down heavy for that. That was a full screen practically. Nice. There's a down heavy. All right. Got to start changing up the approach coming in for those air dash overheads the same way every time. It's just not going to keep working. Get that sword away from me. Let's go. Maybe I could throw in a little TN or is that, uh, is that, uh, don't even think about it. Krillin, get this man. Hit him with the classic combo. Oh, yeah, that's that's death. No, I dropped it.  The Key Blast animation killed him really quickly there. It was like half the Key Blast. Back up. All right. This is where we change out just because that any blue health is good blue help to recover thought about down heavy. But that's all that's all I can say is I thought about it. My hands didn't even move to the heavy button. I was like, ah, nah, overheads. We blocked those overheads. We blocked those defense. All right, we out. Oh, we're back in overheads. We blocked those. All right. Well, we didn't do much blocking, but at least we survived. Wow. Seven bars. Let me spend some of this. Who needs seven bars on there on on person. Get get this out of here. Another successful super dash. Haha. All right. We're going to go for a little bit of extra damage here. But again, we don't want to keep too much. But to bring it back. Bring it back. Krillin. Don't drag and rush. Don't drag and rush. Get him. Yeah. Oh, sit down. Mix up. Well, you got it. Do it again. Oh, wow. He x-links very quickly. I tried to superdaster to make sure the timing wouldn't be any different. I'd still hit him, but yeah, if they act quick enough, they can still get out of that. Oh, it didn't kill deep through it. Damn, deep in through the sunlight. Okay. Uh, all right. Still have spark. I was making sure I was like, did I spark this game? No, we're good. Oh, what are you doing?  So yeah. Okay. We got a level two spark. That's the main reason I don't want to be killing any characters. Why didn't I down heavy that one? That one. I feel like I should have had more than enough time to actually physically try to stop it. Uh-oh. I tried to vanishing. Super late. Okay. Okay. Just Vegeta now. Bring Vegeta back in and let's try to work our way to stopping this. No. Out of there. Oh, he chased us with a super dash. Level one will kill. He opts to do it. We're going to get a free bar here. Level three. Oh, wait, are we going to get it? We're going to go to level four. Hey, four bars. Not too shabby. Nice down heavy. I fell for it. Didn't think he'd have the time. He gets another bar back. That's huge. We blocked those guard. Cancel saved me. I'm back in the corner.  I will forever remember that one. I can't block. I can't block for the life. Me drop it.  Don't send me back. Don't send me back. No. Just don't be too many points.  Let's go easy. How about how about less than 2000? I'll take less than 2000. Less than 2000.  That's like two matches. We're doing 2000. That hurt. That was crazy. Okay. Let's just try to focus on the good. Let's get back to it. Don't lag. Don't lag because we can definitely kill Tingohan here. If we're careful. All right, we're good. That should be Tingohan. Unfortunately, Janemba recovered way too quickly. So we're just going to settle for this. Get him out of here. All right, Janemba, come back in. All right, paging Janemba. Okay, what does he do on start? We throw Key Blast. I don't know why I got that impression of him. I just did. Really? All right. I'm not going to delay it. All right. Give him the feet. I probably should have just gone into a level three, but. Oh, I can't. Okay. I was like, I was like, I can't. Why can't I? Don't spark. Ah, he loves the guard cancel. Oh, that was a well deserved. Drop me, dude. Please. Ah, nice. I thought about switching out into Janemba, but I don't know what the way snap is. It's so dangerous now. Okay. I'm just going to do a level three. Um, maybe I should have gone into Yamcha's level one. It probably would have given me a similar knockdown situation with sliding. That wouldn't hit me. Dang. Okay. Uh, that's going to change the plan. Oh, Janemba's here. All right, we can kill Janemba one touch. Nope. Stop that. Well, not that touch. Really. I can't block these for anything. Okay. Big hit. Man, I wish I could block those guard cancels. I feel like once I start doing that, we could get, we can expect a little bit more damage. Get out. I was just hoping. All right. Don't switch back out into Janemba now, please. Do we waste sparking? The sparking will get us out of here free. Okay. That should be good. I'm just going to, you know what? Forget that. I'm not going to wait. I'm just going to do this level three. That'll get him from anywhere. I don't know if I could have vanished.  But he's allowed. Okay. We're back. Got a win on the board. Show me a thousand five hundred. I can't expect the full 2000. I totally get that. You know, I wouldn't, I wouldn't even want a full 2000. Oh, okay. You know what? Hey, that's not too bad. Not too bad at all. Not too bad. Dude, this is going to be so long. All right. Big dragon rush going to start the game off strong. Now, does he start with a reflect? Yes. No. No, that is a big no. Okay. Okay. Can't believe he didn't reflect there. Does he reflect here? Double two and let's go. Can't do it with Goku, but you can do it with TN.  We're all green. All right. As long as we play safe. We should be able to keep this lead. Oh, we got to switch out to somebody and we can't do it with Krillin. You know what? This is fine because a level three here with Yamcha is really nice. As long as we're in the corner. This level three is golden anywhere else. Not so much. All right. Don't spark or level three. Ah, another guard cancel. All right, blue health. Any blue health I'm going to start taking and he likes the EX leg. So we're going to back dash. Yep. Too slow on that one. I got to start reflecting after the bomb. Once you throw the key blast bomb, then reflect and wait for that super dash. Why do I do that? That assist is not good there. All right, we're going to guard cancel. Give me up. Oh, yes. Oh, we're just, we got it now. That down heavy has sent my confidence into it. Another stratosphere. We are, we are perfectly fine. Okay. Well, we didn't even hit Yamcha, but that's fine. Makes was there. We just didn't bring it home. Get off of me. Okay. Ah, couldn't tech. It's fine. Even that, even that killed a lot of sparking time. Which if you want to level three, ooh, that's a lot of sparking time too. Five by me. And remember, we're not wasting spark. Take that one. Nice. Nice. All right. Beautiful. Could not have gone better. Even Krillin still alive. Okay, let me see if I can't. Let me see if I can't do a little damage myself. Okay. Okay. Give me another, give me another, the same points you gave me last time. All right, dude. We're almost there. Oh, we're almost there. We got even more. Don't leave. Don't leave. Let's make this the last one. Okay. Okay. Fine. Fine. If we have to make it the last one, but the rule is house rule, you can't leave if you win. Hopefully that sounds even Stevens. I'd hate to, you know, set rules that favor me, but if you win, you can't leave. I'm nervous now, dude. Now that this is the last one and this might be the rank up. All right. Like the guard cancel. Remember. Oh, yeah. Dude, I'm going to Pride Trooper. Take me home. Take me home. I'm saying all this now, but when he starts, when he starts hitting those knees in the clutch, I'm going to, I'm going to regret saying it. All right. Do it. Oh my goodness. Krillin, what are you? He Krillin wants to be a Pride Trooper. Dude, he's been here for too long. Krillin's like, I'm not playing no more. Oh, well, I missed. He's playing still. Oh, that was nice. Probably should have tried to down heavy or something. Don't know why I didn't. Okay. This is it. This is it. This has the potential to be it. Get out of here. Big hit. Gotta watch the yoncha, sis. Get down. I'm sorry. Just so I couldn't make the most out of that big leg. We're just volleyball fisting around. Oh, okay. That would hit both of us. That could have actually been the only way you could have turned it around. Well, I mean, he could still turn it around if I start sucking and he starts playing God like, but please don't let that happen. Me just have any, if anything, just raw level three. Please say it. Please say it. Please say it. One, two, stop it. Just stop the toes. Oh, come on. Let me hit him one more time. Another person will just come on. I want it to celebrate. Okay. Show me pride, tripper dude. We're out boys. It's been. Do I have a thank you? It's been a long time coming. So if you've been here since we hit Super Saiyan Rose, make sure to go down below.

Abstract optically active spin defects in Van der Waals materials are promising platforms for modern quantum technologies. Here we investigate the coherent dynamics of strongly interacting ensembles of negatively charged boron vacancy 2665305 VBB 2665305 VBB, centers in hexagonal boron nitride, HBN, with varying defect density. By employing advanced dynamical decoupling sequences to selectively isolate different defasing sources, we observe more than five-fold improvement in the measured coherence times across all HBN samples. Crucially, we identify that the many-body interaction within the 2665305 VBB 2665305 VBB Ensemble plays a substantial role in the coherent dynamics, which is then used to directly estimate the concentration of 2665305 VBB 2665305 VBB. We find that at high ion implantation dosage, only a small portion of the created boron vacancy defects are in the desired negatively charged state. Finally, we investigate the spin response of 2665. We are article.tv, links in the description below.


coming. Yeah, so you know, let's begin here. We have a short time together. This is going to be a brief overview of the work we've done on internet in a box. So myself, Suyash, Tim Moody unfortunately couldn't make it here with us today. So to start with, I'm just going to show a quick video here of let's see if the sound works. It might not be lucky enough. Do we have a, oh, I think I know. Is that going to be the, I guess I should have tested this beforehand. Do you have, do you have a sound cable? Okay, let's try that again. But the unmute is under the slides. A learning hotspot. It could be used on the beaches of Haiti, to the remote woods of Northern Canada, to the Saharan desert in the central of Africa. It could also be used on a rocket ship headed to Saturn. This tiny affordable server brings the internet's crown jewels of open source free education and knowledge, including Wikipedia, thousands of Khan Academy videos, zoomable open street maps, electronic books, WordPress journaling, toys from trash electronics projects, and a whole lot more internet in a box is being used around the world. You could build this offline digital library for your school, your medical clinic, your prison, your region, or your very own family accessible with any nearby smartphone, tablet, or laptop. We are very proud to be working side by side with schools, clinics, and the libraries around the world. This free and powerful software can be easily installed on all types of hardware, from desktop computers to laptops, even a $35 Raspberry Pi. You don't need big expensive equipment to run this lightweight software. Internet in a box is a community driven open source project that greatly welcomes contributions from educators, librarians, IT workers, developers, and anyone else that wants to contribute to the project. To get answers to many questions, please go to faq.iiab.io. Also, check us out on GitHub at github.com forward slash iab. First question is what is internet in a box? It's a very simple device. It's basically what we're shipping as Wiki Project Med Foundation is we're shipping what you see in the picture there. I have one up here up front for those who wants to see internet in a box. And what we're shipping is we're basically shipping a Raspberry Pi 0W. It comes in a 3D printed plastic box held together by four screws. These boxes were donated by one of our volunteers within our movement. We put a 128 gigabyte SD card in this device, which is enough to hold all of English Wikipedia. So what you basically end up with, and as mentioned in that video, there's lots of content options from Khan Academy to other educational resources, including Wikipedia, including MDWiki. This is what we're shipping around the world. We manufacture these devices in Canada. They weigh about 35 grams. We've shipped them to a whole bunch of countries. So currently, we ship the devices at the cost of manufacturing. So we're shipping them for 50 US dollars to high income countries. And then we ship them for about 40 US dollars. We ship them for 40 US dollars for low and middle income countries. And that includes the cost of shipping. So when we ship to high income countries, we make about five dollars on the cost. When we ship to low income countries and middle income countries, we lose about five dollars per cost. And we charge the high income countries a little bit more to make it less expensive for the low and middle income countries. With respect to the number shipped, we began manufacturing and shipping these from Wikiproject Med Foundation. We began in 2017. So we've been doing this now for the last five years. Here's sort of the number of devices we've been shipping over the years. From 60 up to 80 dropped down a little bit during 2020-2021. And now we have seen a recent increase in 2022 to about 50 devices. With respect to where we have shipped them, we've shipped them around the world, you know, including Pakistan, Israel, Palestine, many places in the South Pacific, a number of countries in Africa, including the DRC, Botswana, Mali. The only places we have had trouble with devices arriving is Mexico. For some reason, the Mexico Postal Service, this eats up the internet in a box and they never arrive at the final destination. But, you know, we've had, we've shipped devices to Kinshasa and they've reached that destination. Sometimes it takes, you know, shipping doesn't take one, two weeks like with Amazon. We're looking at shipping times closer to, you know, one to three months. With respect to the breakdown of costs of this device, you know, the 128 gigabyte USD card costs about 20 USD. One of the issues with these devices, if you're going to make your own, is that there's lots of fake US, USD cards out there and you need to make sure that you find a natural real USB card when you're making your device. The Raspberry Pi's themselves, the zero W's are about 15 USD. If you buy them one at a time, they're less expensive than if you buy them in quantities. So, you know, usually Raspberry Pi will only sell one of these cards to a person at a time and they're like 10 to 12 USD. If you want to buy more than one, they increase the price to 15 USD each. So we're paying that sort of 15 USD per Raspberry Pi. And then shipping costs average out to about 10 USD to ship a package by airmail around the world. There's no tracking involved. It's just not worth paying that extra amount for tracking. You know, one of the things we'd love to support is we'd love to support other people within our movement, making these devices or assembling these devices and then distributing them locally in your own country or in your own region. And that could potentially cut down with, you know, on some of the shipping costs and, you know, sort of distribute the labor of assembling and manufacturing these devices. Now, we have, as I mentioned, we have an internet box here.  And if you click on Internet in a Box, you will be able to log on to this miniature computer in my hand and you will be see, you know, the two slices of information there. One is MD Wiki, which is sort of a medical version of Wikipedia and the other one is the whole English language Wikipedia. So once you, with some people's phones, Active Portal will pop up and that will bring you to the home page of Internet in a Box. On other phones, you need to open your browser and you need to type in HTTP colon front slash, front slash box.lan. And we've written that on all the boxes that we distribute just to help people get to that starting point. Make sure there's no S. The S stands for security. That requires online access to get an HTTPS site working. So all we've managed to do to get around that, we were just using HTTP. It's also possible to look at what the site looks like online. So you can, you know, sort of view a version of what's on the box or one version of the box by going to HTTPS, the lower link there, colon, front slash, front slash, IAB.me, front slash home. And you can see an example of what we're shipping. We will often customize these versions for different folks and add specific languages if people aren't interested in having boxes with specific languages. Anybody managed to log on? A few folks. Yeah, it's a little slow. You know, this is a Raspberry Pi 0W. One of the reasons why you went with this very lightweight server is one is, you know, the cost is low. Two is that they're super small and they're easy to ship and, you know, they come in just a normal envelope. So, you know, the people at customs won't realize it's something expensive and thus won't go exploring people's mail most of the time, except for Mexico. Okay, so that's sort of my overview of how Inner A Box has done this last year. I want to invite my colleague, Suyash, to come speak about some of the modifications he's making. Thank you, James. Thank you everyone for coming here. So yeah, like James introduced that device very well and while exploring this device and using in real things, I realized, we realized that something it is good that the size is very small and sometime it is challenging because if you want to place it in public places, then a size may be a challenge. So let me introduce myself. My name is Suyash Devedi and basically I'm from India and yeah, I'm currently having twice here as a comments photographer user group and I also serve at FCOM. So I think this slide is already covered that what is Internet in a box. So I am skipping and first image you can see that is already there and second one is a little bigger size with the enclosure where we can put it into the public places and the third slide is how it looks like to your mobile screen. The good thing of this device is that you can build your own. It doesn't require much engineering if you are if you have a colleague of some techie colleague so he can guide you how to build this and all the resources related how to build it is available. So basically during using this particular devices I found three problems. Not problems but enhancement which can improve the performance of device. First thing is that like the each and every other computers it should have some hardware based shutdown because you cannot you know directly plug out and shut it down. So first problem was that that we need to you know put some hardware based shutdown system. Another one was the enclosure because if you want to place it in like I earlier said in the public places like it is really very useful for the places like hospital where people are waiting with their patients and they can they want to explore more about the disease or anything extra so they can utilize that waiting time. And third thing like because you know since it has been primarily focused to those places where internet is a limit so same places sometime powers is also challenge. So these are these were the three challenges. So this is solution number one. There is a very tiny it's a hardly 20 cent add-on device where you can you know put a switch and wait for five second. If you keep pressing for five second it will hardware will get properly shut down and this is a quick click how this hardware means this Raspberry Pi the left one is the Raspberry Pi 0 which currently we are using this device and the middle one is Raspberry Pi 4 version which has more memory and it can covers and speed can get you can get the more speed. So yeah this is the quick solution all you need to put one momentary switch one LED indicator this is optional it will indicate that whether your machine is running and whenever you press this little button it will flash for few seconds it will be giving a indication that it is going to be shut down and that's it. So a little Python script is written for this and it is also available on github Okay I'll make sure that this slide will be available on common so you can go through that link also. So coming to the next solution that is enclosure. So enclosure was you know as I earlier said that sometimes the little size is challenging and we are very thankful to our colleague who is donating this 3d printed enclosure but here is a very quick acrylic based enclosure which you can this design is already available on commons so you can simply go to the acrylic 3d cutter center and get these enclosures. To like I earlier said that I have shared the all the links and codes related to that printed circuit board which helps you to make this device hardware shut down things and along with this design of the acrylic sheets. Third thing was like solar based power supply system. So we are just thinking and we are into the process where we are trying to make these devices powered by the solar energy so that it can run along and even you can put these devices to the your local village pump is not the Wikipedia village pump but the real one where you can utilize these devices not only for the education purpose but you can also these devices can also serve to the farmers to know the what type of crops are there and what type of diseases are coming and that it's remedy and so on so. So even it will be very helpful to as a you know information tool that these types of grants are available for the farmers or these types of you know applications or the farms are available they can simply download and then they then they can use it and that's it. So this third one that challenges under process. Any questions? Yeah please. Thank you both of you for this wonderful presentation. So the question is that these devices are for those people who don't have internet availability. So what if when we talk about villages where there is no internet but if there is no internet there there the smartphones are also challenged there. So how we are going to tackle these problems. If any village don't have problem sorry don't have internet there must be no good smartphone and this work with smartphone. So how you are going to tackle these problem. You know one use case of this was in Central America where you know the medical students would train in the large cities where they had access to lots of resources and then once these students graduated from medical school they were sent out to regions of Central America where there was no internet access. So all of a sudden you have all these newly graduated physicians who have no access to the resources that they're used to having and you know they're starting out in their career and they know barely anything and so you know that was a perfect use case as you know these students already had these newly minted doctors already had excellent cell phones but they just all of a sudden were in a region where there was no access and you know we're starting to see people in many regions where there's not great internet access and yet they still have smartphones. You know getting smartphones to everyone you know that's not going to be a solution that's going to come from us but there are you know lots of efforts specifically in India and other locations where large companies are working to make inexpensive cell phones that can be distributed to as many as possible. Yeah thank you very much my name is Ruby from Ghana. I'm very much intrigued about the work that you were doing regarding internet because I understand from my background how this is a very big problem. What I want to understand with the device that you use and I wanted to I want to know how many people can use it at the same time and secondly do you program the content on it before you ship it and what happens if the content needs to be updated do they ship it back for an update? Yeah so that's just what I wanted to know. Perfect yeah I'll take the first part of the question so if you open up this device so at the time 32 people can join and if we if you use some kind of extender like Y5 extender then you can means more people can log in at the same time and yeah second part yes yeah so you know with respect to the updating of content so you know we we compile these and fill up the sd card before we ship them so it's shipped with English Wikipedia and generally other resources already installed and and then with respect to updating you know it's difficult to get updates you know in the olden days when we used encyclopedias you know we had less expectations around the encyclopedia being updated in the prior months or weeks you know we would use the same set of encyclopedias for months years you know even a decade at a time and you know that was seen as being reasonably up-to-date. You know with respect to providing updates you know I know in Papua New Guinea there's a gentleman who's bought a whole bunch of these devices to distribute around the country and one of the things he struggles with is the internet in his location simply isn't good enough to download the entire Wikipedia for offline use so when he wants an update he just simply emails me he sends me another sd card or you know I grab one of my sd cards I put new content on it I mail him a new sd card and then he just pulls up the oldie sd card and he plugs in the new sd card and he continues on with the updated version but how often do you need to update it you know probably every couple of years is more than sufficient Hi I'm Davul, I'm one of the Gujarat in the equine quivered in a couple of questions here one is the stats the boxes that Suyash said which he's assembling or his team assembling are they the same boxes or numbers are the same within what your graph was showing or they're out of that number because I see your list of countries included in India as well so that's one thing the other is the stats of usage have you ever tried to conduct that kind of survey that how many people logged in different IPs recorded etc just as an interesting piece of session yep so so you know we did have a manufacturer slash assembler of these devices in India it was called Thingbits and they they made a bunch and they distributed a bunch from India to India but they have we're not quite sure why they're no longer doing so so we're looking for someone else in India interested in taking on that work these stats do not include the numbers distributed by someone other than us at Wiki Project Med Foundation so that's the first part of the question what was the second part again how how widely they are used like once you're distributed that data yep so you know ourselves and and Jorge did a study in Nigeria with respect to usage of these devices they were our previous versions so we were we were they only had like a 32 gigabyte SD card they didn't contain the full Wikipedia and we gathered some data around usage from they were put in health clinics in Nigeria and you know there was decent usage but the only way to actually calculate usage is you need to get the you need to get the device back yeah before you can pull the numbers off right and most of the time we're not doing that we did that for that small trial in Nigeria but that's the only yeah and sorry just one last quick question do they do the Raspberry Pi that we use does it support the other languages other scripts etc when I say script the the scripts in which we write uh other than English or Latin script yeah yeah so so you know there there is a massive quantity of content you can pick from to put on the device you can pick any language of Wikipedia that you want and you can put it on the device thank you hi James hi it's a great project like it is it sounds very interesting so this is it is only being used to consume the knowledge by using this particular data in mobile devices is there also plans to also give back the knowledge using this device using editing and stuff yeah so if you log on to the if you log on to the internet in a box that that we have sitting up here you can actually there's one there's three different modules on there there's md wiki there's wikipedia and there's a blank media wiki install and you can actually open that blank media wiki install and you can start writing on there yourself um and you will when you hit save you'll be saving and changing that version of media wiki that exists upon that individual box we don't have a method yet for that material to flow back into wikipedia but you know if you were to you know take a class have a class work on that one version of an article on that internet box then you could theoretically take it to some place where internet exists and you could re-put that you know into wikipedia okay thank you but complicated and requires some legwork perfect any other questions um i saw that was like what $50 or $40 right but do you have like a paid forward sort of thing or a donation account where you know if i don't need it but i think maybe someone's needed i could sort of put something in yeah certainly so you know this this um the distribution of the device is supported by a 503 um new york-based ngo called wiki project med foundation if you look at wiki project med foundation if you go to like md wiki.org um there's a donate button and you can donate to the charity that's you know we'll support the distribution of these devices but we've also seen many people you know like some devices have ended up in cuba um and you know people in ireland bought internet's in a box i ship them to ireland and then they put them in their suitcase and they carried them to cuba and then you know they fired them up in cuba so some region of the world people are you know they need to carry them across borders i imagine the same would be required for like north korea as you know the post is probably well checked there whether or not someone would you know bring in a device and sort of second set it up somewhere that would be a possibility so and yeah you know with with respect to sueyash's idea you know of you know we're we're looking at steps to make standalone devices where you know you have the battery included you have a solar panel included you have a bigger box um you know that can protect the device and sort of having something that's just ready to go out in a place where there is no electricity or there is no internet access and sort of you know you could put this in the center of a village um and you know this could be sort of your your your town pump where people could access um a library so thank you everyone for coming thank you and ruby are you up next excellent so we have another we have another qx flash internet in a box sort of related talk


Welcome to NPTEL course on groundwater hydrology and management, this is week 3 lecture 4. In this we are looking at some important components of groundwater hydrology and we have been defining what is groundwater, how is it stored and what are the key components. In today's lecture, we will be applying the understanding to differentiate the different Indian aquifers in the subcontinent. Since as I mentioned earlier, this course will be focused more on the Indian groundwater system, we will be looking at the Indian aquifers. At this point, I also want to stress that management of groundwater is very important for India. It is one of the most important freshwater resources in India, if not the most. It accounts to almost all of the rubby season cropping in major seasons and major regions of India. And also we are ranked number one in groundwater extraction. So the major types of Indian aquifers are hard rock aquifers of Peninsular India, which is present around 65% of India and it covers most of the surface area. The central India would be housing most of these hard rock aquifers. So aquifers were defined in the previous lecture wherein it is the unit of storage inside the groundwater profile where you have pore spaces and solid medium and water is filled in the pore spaces. The aquifers can be confined and unconfined. So what do you mean by hard rock aquifers? It is underlined by hard rock formations. The rock is hard, all rocks are hard, so you would ask me what is the difference? Hard rock means it is hard to crack and weather. So because of that, there is least weathering and the weathering is almost along a single line or a fracture. And because of that, there is less pore spaces. The rocks are kind of platey and are on top of the other with less space in between. Suppose you have a rock which is having different dimensions, it is not smooth, it is not circular, so what happens? They cannot overlay on each other and so there is space in between. However, if it is platey like this and there is only cracks in between, it still can gel together with less space and that less space gives rise to only less groundwater. So as the writing says on here, these rocks give rise to a complex and extensive low storage aquifer system, low storage because water takes time to get into this system and also it is hard to extract water out and it rapidly falls once you extract more and more water. And the permeability is very low. How much water can pass through the system is very low, pass through the rocks is very low. So there is both recharge low, storage space is low and also once you pull it out, the next recharge is very, very slow and there is no connectivity much between the aquifers. So this implies that the water in these aquifers is non-replenishable or not quickly replenishable and will eventually dry out when you use it continuously. Given that it is almost present in 65% of India, it is scary to say that this is the water that is being depleted constantly and is not being recharged. So all the benefits that the farmers and industries and domestic users were enjoying by using water from this hard rock aquifers will soon face a shortage if not now and their attitude in using water has to change or will be changed. What are the remaining aquifers? The remaining aquifers are called alluvial aquifers of the Indo-Gangetic plain or alluvial aquifers. So you do have alluvial aquifers in the southern plain in the Kaveri delta and in the western side along the Narmada region. So most of it is in the Indus, Ganges and Ramaputra region. But the majority of alluvial is formed in the Ganges Plains. So these are in the northern India and have significant storage spaces and hence are very valuable source of freshwater supply. The Ganges Basin, the Ganges area totally can support more than a billion population both using surface and groundwater. When you say a billion population is supported that means almost one person every seven of the world population is supported by the Ganges Basin. Such an important basin and there is a lot of groundwater storage there. However, due to excessive groundwater extraction and not as fast recharge rates which means the extraction is happening 10 times the natural recharge rate. You're taking a money like 10 times in a day and putting only once in a day the salary or let's take it a month. So that means you are extracting at a much faster pace than the natural recharge. These aquifers are always at risk of irreversible over exploitation. What do you mean by irreversible is once you go below a particular water level you cannot recharge the water and that actually would cause tremendous stress on the groundwater ecosystem in the Ganges Basin. Let's look at this visually because visually you could make more sense of what is happening and what are the driver forces. So principal aquifer system first we'll deal with the alluvium aquifers. Alluvium is the term which comes from deposition of minerals solids and sediments through water. So you have water carrying these sediments and it deposits along the way. These waters could come from the Himalayas and in between regions it carries a lot of sediment and the sediment are fine particles. If they get deposited then water can get into these sediments because of the pore space. Sediments have a lot of pore space. So most of the yellow region here which is the Indus, the Ganges, the Brahmaputra are all alluvial aquifers, very high yield. There is some here also due to the Ganges Basin and etc. And here you have some on the Cauvery Delta region. Here you could see on the Amar Madhavati region. What else do we have? We have the Lattrite in orange very less amount. So let's concentrate on the major aquifers. So first is your alluvial on the picture. And then you have the hard rock basalt aquifers. So the term basalt comes because of the nature of the rock, the name of the rock. And basalt itself is a hard rock. So in the previous slide when we mentioned hard rock aquifers, it is not the term given to the formation of the rock. It is the rock itself is a very hard rock and it doesn't disintegrate that fast. There are multiple types of hard rocks and that is what we are seeing here in this image. The blue color which represents the basalt and the orange color, more in the Lattrite and Limestone, etc. And granites, granites in the blue color all constitute your hard rock aquifers. In southern India, in Tamil Nadu and Kerala region, you have the cortite. And those also constitute your hard rock aquifers, very, very less groundwater potential and nieces, G and E, SIS. All these are your geological terms for the name of the rock. And the rock is a type of a hard rock because it doesn't have enough space, porosity is low, permeability is low. It is very hard to weather the rock. And because of that, there is less groundwater storage potential in these aquifers. Moving on, we also have a shale along the northeastern region, pretty much covering the northeastern region. And here you have the hilly regions, schist formation, very, very hard rock, not much groundwater potential. All those are the Himalayan regions. And you would expect a very less groundwater potential there. So the principal aquifer systems is, again, based on the geology. Okay, first is you need to have a container to pour the water. And that container or that storage unit is your groundwater aquifer. And the aquifer is a function of your geology. Names you see here is alluvial aquifer, et cetera. So here don't confuse it between the unconfined aquifer, confined aquifer and alluvial. Alluvial and the names you see here is predominantly the rock material. But when you say confined versus unconfined, it is the presence of an impermeable membrane or a rock surface and how it recharges. So it is more on a function of recharge, whereas here it is a function of the geologic material. Okay, so you can have a hard rock confined aquifer. You can have a hard rock unconfined aquifer. Okay, so the unconfined, confined can be added to your hard rock. And so there's only two types of aquifer system based on the recharge and movement of water, which is confined and unconfined. And the geology can be put in front as hard rock aquifer or alluvial, confined aquifer, alluvial, unconfined aquifer. Here we're just looking at the base material, which gives the space and rock materials for your porosity to happen and that porosity stores groundwater. Now we're going to take another map by the Geological Survey of India. The previous one was from the Central Groundwater Board, where they do a lot of work on groundwater, whereas this one is based purely on the geology. If you look closely, the geology doesn't change much between years or even decades, because only the weathering happens, but the material is the same. So if you go here and see quaternary, it is only going to be quaternary for 100 years, 1000 years. And it can change only the density or how it weathers. The geology is the same. It doesn't change much. Right? So this is a permanent property of the location. And depending on how it weathers, the porosity formation happens and in that groundwater can be charged. So based on the alluvial aquifers, you can also have the same method here. Most of Central India is having the Jurassic geology content. Whereas along with your Upper Pelsoic and Lower Mesoic of Himalaya geology type and your alluvial aquifer plane, where you have the Indus, Ganges, Brahmaputra, etc., those are the quaternary geology. So the geology also coincides with the alluvial aquifermatic. So that is what I wanted to show here, that your geology plays the key role in formation of these alluvial aquifers. And then when water comes in, the storage happens. And depending on the rainfall and your extraction, recharge and discharge, the groundwater yield and potential can be mapped. So you could see that both the aquifer map and the geology map are almost similar and they derive the names between each other. The geology plays the vital role. In hydrology, we call it hydrogeology, which means a geology which is used to explain the hydrological component. Here it is the groundwater storage. And so we call the groundwater parameters in the geology as hydrogeological components. Moving on, let's take a look at the groundwater potential and yield that happens in these different aquifers. The aquifers are mapped again as per how much chrome water you can extract per second. And it is given at yield at liters per second. Okay, so you have the alluvial and unconfined, the major aquifer systems. One of the major aquifer systems with 31% of the area, you have dark blue and light blue, which are covering them. You could clearly see that along the major channels of the Ganges basin, if I put the Ganges shape file on top of it, you could see all the major rivers and tributaries of the Ganges along this blue, dark blue area. And that area has almost more than 40 liters per second yield. And that matches with your quaternary map, which is a geology based on sedimentation. There's a lot of sediment smoothing and that's still a young soil. When we say young, because it's not stopped, still you have sediments coming and settling in and a position making these layers up. And these layers can give a way to confined and unconfined aquifers, as we discussed earlier. So here your alluvial aquifer system, which is one of the major aquifer system, is predominantly placed in the northern region and also along the coastal regions. Why would it be on the coastal region? Because most of these sediments from the inland are brought to the oceans and deposited. So while it comes to the ocean, the deposition happens right before it merges into the ocean. We call that as a delta or a fan. So water brings all the sediments and then when it hits the ocean, it starts to spread and deposit all the sediments. Now these sediments are fine particles, as I said, very small. And when they are put together, there's a lot of porosity, a lot of pore spaces in between. So that is where water can go in. To understand this better, you can think like a sponge. Take your normal sponge that you use to wash your vessels at home, a yellow sponge with a lot of holes in it. And that holes represent your porosity. So now if you fill water, what happens? The water goes into the holes and gets stored. And when you lift it, some water will come down, but still water is stored in the sponge due to surface tension and holding capacity of the sponge. The same way, here your alluvial aquifers water gushes through it. So if you go and play in the beach with the sand, you pour water, water just flows through. And that constitutes an alluvial aquifer. And what happens is water goes through. It's easy for the water to go through and easy to extract the water. The alluvial aquifers are not as sandy as your beach, but still it can hold, and that is one of the reasons, it can hold the water for a longer time. So moving on, the hard rock areas are mostly in the central region. And semi-consolidated rocks. The rocks are hard and slightly weathered, not fully weathered. Those two constitute the major portion of the Indian aquifer system. So now if you look at this, is it very sustainable? Someone can ask me, is it sustainable to use so much water in a year if the major groundwater aquifer systems are hard rock and semi-consolidated? The answer is a simple no. If your major aquifer system is a hard rock, semi-consolidated rock, with very, very low porosity, which means low groundwater storage and low groundwater yield, you can see the yield here, just 1 to 25 liters per second max. Then what happens is your use does not justify the recharge rate and the geology in the country. So something serious would happen if we don't change the groundwater use pattern. Because we may be using it for improving the productivity, sustaining crops, fighting climate change, because when there's a flood or a drought, there's less water for the crops to grow. So you use groundwater, all these things are good. But if we don't use it cautiously, we will lose the groundwater because most of the aquifer is a hard semi-consolidated rock, unlike other regions of the world. The hilly areas are also present, mostly along the borders of the country on the north, and those have very, very low potential, less than a liter per second. And if you think how much water is needed for domestic use, you would understand that these waters are not that much conducive to use. That is why a lot of people walk miles to collect water for drinking and bring them back home. So if you go to the central part of India here, where you have the consolidated and semi-consolidated formations, there is a lot of lag in the recharge time, which means you might have a good rainfall year. You might have a good water availability. However, it takes longer time for the groundwater to recharge. And as a result, you would only see the benefits two or three years later. And this is a reason why people have to understand that just because we had a good year of rainfall doesn't mean our groundwater is going to come up. It will take time. So you should not deplete your groundwater because the next year could also be a drought year. So to fight the droughts, you have to be careful. It is like always a small amount of water should be kept as a safe limit. And we will be discussing these limits that the Central Ground Water Board has proposed in the next lecture. Moving on, there are multiple authors that have looked into this aquifer system of India because of the very high dependence and high utility of these aquifers. For example, this map from Germany, you could see that the Indus and the Ganges basins have very, very high yield and very high recharge. In the previous image, we saw the yield potential as liters per second. Here it is millimeters per year, which means a thickness of water per year. And here we're going to look at the recharge potential. So if the recharge is high, the yield is also high because if you can get water into the system, you can also get water out of the system easily. So that is why you see the same aquifers mapped where the yield was high. The recharge rate is also high. And these are mostly along the unconsolidated aquifers, okay? They're unconsolidated, they're unconfined, most of them. And they have a lot of pore spaces for storing the water. And if you plot the river networks along this, you can clearly see that wherever the major rivers are, especially the Perinean rivers, you see a healthy unconsolidated aquifer because there's always movement of sediments and rocks and that gives rise to this kind of an aquifer. And you have good recharge and yield. Let's take, for example, the Indus basin, the Ganges, tributaries, the Cauchy, all draining through Bangladesh would give a very good aquifer system. So in fact, the entire Bangladesh region is blessed with a good aquifer system. There are some water quality issues, but it's pretty good in terms of water, both surface water and groundwater. Similarly, a Brahmaputra region also has good groundwater yield, totally because of the aquifer led by the formation of unconsolidated sediments. Moving into the central location, it is formed by more complex crystalline hard rock aquifers, some of the regions are very high. So if you look at this region, it's almost as high, greater than 300 millimeters per year, is almost as high or higher than the Ganges basin in some regions. Why would that be possible? Because this region, if you know very carefully, this region is the western guard region, whereas you have a lot of these western guards and slopes, the big hill range change. And these hill ranges have a lot of erosion which gets deposited and that deposition becomes your aquifer. So if you have a hill region like this, the hill on the top is slowly eroding. So that's why when you go near hills, you see rocks falling down, you see a lot of small broken rock materials. Always there is erosion. The erosion happens because it is exposed to sunlight and water. These two elements would break the rocks very, very slowly. It's not like every day you can see a hill breaking. It's a very slow process and cumulative process. So when there's a big rainfall, what happens? Most of the erosion happens. All these broken materials are piled up along the foot of the hill. And you know that this side of the western guards gets a lot of rainfall compared to the rain shadow region. So on this side, there's a thick formation of aquifer because of your sediments and erosion and sediments. Both rivers also bring the water down. Along with the water, there's sediments which come down. So that forms a good aquifer and has very high recharge rate. So most of central India does not have that high recharge rate. It is very in the medium and low range. And then when you go to the South-Austral region and the Hilly regions, you have the minor groundwater basins with a very low recharge compared to the unconsolidated and complex and not many major rivers are present. If you look at the brown regions, there's not many major rivers present. So all the major rivers are in the alluvial aquifers. Look at this, Descaveri, Krishna, Madhavada, Brahmaputra, Ganges. And also you have the Hilly regions with good rainfall in the high complex, high-linked complex crystalline aquifers. So we've discussed aquifers, we've discussed the Indian aquifers and how the Indian aquifers are delineated based on the geology. And then after the geology, we looked at how it is based on the ground potential to store the water, which is the porosity as a function of the geology. And we came into terminologies like alluvial aquifer, hard rock aquifers, et cetera. Then we also looked at formations, how the rock is, what type of rock is formed in the geology map, along with the rivers in this particular image. We have clearly seen that there are multiple physical factors, river, rainfall, geology, which influence the type of aquifer and the yield in the aquifer. So this information should be carried forward. And if you see it, there's not much difference in the central India, but if you go to small scales, you will find some heterogeneity, which we will be discussing in the next lecture. I would like to conclude the chapter on Indian aquifers and we will be soon discussing the hydrological parameters to the ground water flow. Thank you.


The paper discusses the challenges faced by India in managing its solid waste, including inadequate collection, transport, treatment and disposal systems that impact the environment and public health. The paper highlights opportunities for sustainable solid waste management through waste segregation at source, specialized waste processing facilities, engineered landfill sites and waste to energy facilities. However, a key barrier to implementing these solutions is the shortage of qualified engineers and environmental professionals with experience in delivering improved waste management systems in India. This article was authored by Sunil Kumar, Stephen R. Smith, Jeff Fowler and others.


Okay, so everyone, thanks for coming and for your opportunity to have a demo effect of course, but let's see at the demo I'm going to undo that. So I would be honest, I'm the team co-maintenor for the module for the graphics, let's say memory management and graphics. Submission would be my deal and then there would be young people and in this place and then we have proper clouds. But I have a kind of history with having remotely access devices because usually any device that you are going to do with new data will be closer to the factory than your home, so either you will be traveling. Better now? Okay, thanks you. Yeah, so there will be always remote, so there is a certain amount of pain in the right to access them, so I decided to share my experiences with you. So I'm going to briefly go over what it actually means in this context that I'm talking about and then we'll go about the open source solution that there is for this issue. So the question is to how remotely access machine property development, so it's kind of different for many developers when they are accessing, they are mostly using the HSA and locally. So in order to kind of open it up a more we need to kind of think what it means to be using remotely. So when you have a device on your desktop, you would be using it. But nowadays anymore so much, but it used to be, it would be using serial port, it would be back some early booting issues. For example when you use a KMS there will be deadlock and together else it won't come up. So that will be a way of like the last result. Nowadays it's going to be harder because fewer parts will be having serial port, but it's easily accessed port. So there is nowadays the USB debug port and even for the USB 3.0 you have an alternative. But the support is kind of like, I've tried to set it up a few times. In mainline it's correctly hard to get working. So I think net console is kind of go to solution, but that can solve only so much. So I have highlighted points in the slide that normally be for traditional use to be remotely accessed. Not only the remote desktop, so for somebody purely working on the 3D side and the user space, they are probably fine with the desktop user. But for the kernel you really want to know if you're kernel mode setting is working and if you want to go to BIOS and you want to be able to fix that BIOS. Because usually, yeah, especially the new devices, the BIOS will be a little bit flaky at times. And then for that you need to keyboard and mouse or SSH, why not? Even if the chips have been in the use for remote accessing, but it's not been in the positive side lately. And then it's the USB sticks, that's also something, so you probably want to download the BIOS to somewhere and then also be booting whatever you get to report from somebody that it's not working on this specific distro. So you want to be like booting that with distro also, so all that. And power control is pretty so. Martin is still here, but for example the kernel team. So there are various solutions for depending on how much money you need for controlling the power of the devices. But that's of course something. Definitely be yhdening the plugs if you have the device on your desk. It's simply not doing anything, but so you need to be able to do that remotely too. So here it's kind of a simplified. I have assembled the system here on my desk, but it would probably be easier to look up from the slide. So this is what you would be kind of expecting for through it. And it's also shouldn't for, let's say open source, contribute or it probably shouldn't be too expensive either. There are lots of KVM IP solutions of course, but you can't modify those and you can't reverse engineer them. To start with something open would be kind of a nice touch. So I have been looking and trying quite a few different things. And I came down with these for at least current time. So I'm always looking for the next kind of alternative. So it's not a Raspberry Pi unfortunately. So it's a vehicle phone for back, because the Raspberry Pi won't give you the USB gadget. And then the Raspberry Pi zero that do get you that they can be. Well, you have to do soldering if you want to power them from a easy power supply. So I think one idea here is because we are going to be deploying in lab environment. And I won't be necessarily there to do the soldering. So it has to be kind of be able to be put together by the lab engineers. And then I'll just be able to use that machine. So for the vehicle phone black, it will basically be, the main line camera will be running. But obviously PI hasn't been completely perfect with all the bad things. So the performance if you are, for example, looking to do some network routing with the device. It's going to be on the bad side. But they also have been working on kind of building of the, you know, you can download, you can flash it. And it will go where from, right? It's 4.4, I think. So it's not that open. And then there's, yeah, there are also, I'm not sure how much main line is being run on those. These single board computers, because for example, when I tried the main line camera, I found that there has been for half a year. So regression in the vehicle phone black device 3, that it will basically make the USB. That's unusable before you revert that. So it's, so yeah. You know, that's just if you want to get those cheap off the shelf components, you might have to end up using the AI provided terminal in this case, for example. So yeah. And then the linking HDMI center will be, you just order it from your random eBay vendor and they ship it to you. It's about 30 euros. And it will basically work out of the box. But I know that there are a lot of hackers here. So I guess there is a lot of reverse engineering and you can, there are alternative firmware to the device. You can basically get it to go up to full HD and then do pretty much all the resolutions down from full HD. But even if you get it, when you ship it to you from the eBay, it will be doing both 720p and then full HD. But it will be downstaying the full HD to the 720p. But that's actually quite convenient because when you are, for example, running benchmarks on your remote device, you're probably going to be comparing to somebody. The recorder probably had full HD display or nowadays would be 4K2, but full HD is still kind of standard for performance. So you will actually get the preferred amount numbers called the full HD, but you only use the 720p. And when you're over, well, you're going to be getting connections to whatever site you need to be accessing. And then it has some quirks to the device, so it's sitting UDP, luggage of zero length, so that's not exactly illegal. But most of the software currently in the latest version of it, I think it won't match with that. So you probably want to be doing firewalls from those. So yeah, it's quite straightforward when you get the cable connected to the device. You can tell the device it's always on, even when your machine isn't putting any HD in your signal, so you will actually get no signal. So it's convenient, but you need to check the proper effort. Even if you would be using SSH to launch the performance like benchmark, you would be viewing them from the screen easily. And then you have more G-streamer, but unfortunately with this specific device, G-streamer is rattling when you are doing kernel mode setting or whatever mode setting, kind of resetting the encoder. Time-stamping numbering and that will stay down G-streamer, unfortunately. So if somebody is expert in European emails, you know, because G-streamer otherwise actually will result in a smaller latency between interactions and then the video. So I prefer that. And then I will tell you also, this recorder takes everything, you know, you can also, if you're interested in only the picture part of the screen, it's easy to strip it out and then you will be saving some of that video. And also because not all networks are creating equal UDP, kind of difficult things, so you can combine with the legal complex here, just make it the proxy either with visual cats or we can do it the way. But I guess you might feel that UDP is now being replaced by a commercial product. There are some patches, there was even one that could be switched. Yeah, so, but you will do it with a much lesser load, so you will be able to do other UDPs with, for example, transferring files into legal complex. So for controlling, of course, as this is going to be about the open source usage, and we already have a great USB gadget stack in the Linux kernel, so you basically don't need anything else. So from the Bigelobon black, you will be plugging the USB gadget cable to the host device and that's it, you won't be able to have your mouse, keyboard, serial port and any masteries gadget there. So basically that will fulfill most of the needs when you already have the display with the HDMI in order. And this is the way at least. How I started it, when you really, really just need to get down to the command line and you can write to the... Hit the grid, or you now like to hit packages like raw. Here I will highlight it, so it's a bit like you would be programming local or something, you try to hit that button, it will go a little bit too far, you need to come back a little bit. And with the keys, of course, there will be, because the hit protocol will only give you the changes for the keys, so you have to be a little bit smarter and write a grid that will hide in for you, but it's easy to generate those even for all lengthy command decisions. And then there is a caveat that, if you're wondering why it's not working, you probably don't have to play correctly for your... So when the demo, there was time, I think I go through the rest of the slides and then let's see for the demo. So from what I've described here, because you might have some delay with your network, it might be more beneficial instead of sending the complete hit report from the remote machine, the destination task, send an indication that I want. But don't press for a period of time because otherwise you will be hitting those sticky keys and going to that, you know, script that you have been running. And then how many was brought up when I demoed this at our office? So yeah, it's going to be one press per second. Currently you can get to 60 frames per second with the native encoder, but then it's only HDMI and we're not sure how long this will be available. I hear that. How many will be even better if I'm not necessarily on the decoding side because it's not a thing for them, but it might be in the future. Okay, so how much do I have? Seven minutes, so. Okay, so it's... I'm hopeful to have this from that. And if there are any questions in the... Again, please ask out my question. It could be not related, but I was presenting about making the remote access. I've been accessing the message remotely for quite a long time, trying to come up with something smart, including QR codes and webhams, and trying to find what's most end-recommends part. This is something that... Well, it wasn't like a few minutes ago. So I guess then it's... If any questions, not then I will have to... Okay. So if you're not specifically trying to debug it this way, have you looked into other options, like using the GPU for rendering, but I'm looking after trying to forget something BNC like? Yeah, so as I'm working with the Ion 15 driver, we are not even... I'm not even on the display side, but in the memory management. So usually when something goes south, we don't maybe even get any buffers, we just get the UFI console. So it's kind of... So I haven't been doing that, but that is of course an option, and it should be pretty easy to do with the... You can have prime export of the display surface. Any other question? So if not then I will thank you.
