Hey, welcome back everybody. Jeff Frick here with theCUBE. We're in Reno, Nevada at the Inner Bike Show. It's a big show all about bikes and mountain bikes, but we're here really to talk about e-bikes, because e-bikes is this new class of really transportation, not really new. Turns out that Gazelle's been making them since 2002. So we're at the Royal Dutch Gazelle event, an adjunct event next to Inner Bike, and we're excited to see they're releasing a bunch of new bikes, and really dig into what are these e-bikes all about. We've been told that the United States is a little bit behind. You're starting to see them show up. Is it a last mile vehicle? Is it a primary vehicle? What are the laws and regulations? And we're really excited to have our first guest. She's been dealing with this for years and years and years. It's Karin Wiener. She is a co-owner of the new wheel. Karin, great to see you. Thanks, thanks for having me. Absolutely, so give us a little background on the new wheel. Where are you guys? How long have you been around? What's your focus? Yeah, the new wheel is located in San Francisco and Marin County in Larkspur. We opened in 2010, so about eight years ago. Excuse me, out of our apartment, because we realized that nobody was really seeing the opportunity in this transportation alternative. And so we were seeing what was happening in Europe, which, like you said, has been happening for a while. And we realized that, gosh, San Francisco is the perfect place. It's an obvious match. An electric bike, which basically amplifies your pedaling power, acts exactly like a bicycle, except for you're always in your best shape and having your best day and having the most fun. And so we started with basically one bike, or three bikes, and we had a mobile shop that we would ride from farmer's market to farmer's market. Then we opened our first store in 2012, and we're still in that location in Bernal Heights in San Francisco, and we focus on curating high-quality electric bikes that are gonna work really well in San Francisco, which, as you know, is a really rugged, especially in terms of elevation gain environment. So what if we could talk about some things, some myths or not myths? So one thing is, while we came here as we were really looking at e-bikes is really a last-mile vehicle. And that's kind of in the line of smart cities and kind of this multimodal transportation. Do you have a Lyme scooter to the Caltrain? Maybe it's your car, maybe you've got your own bike. But what I'm hearing here is these things are a lot more than last-mile vehicles. These are actually substitution vehicles for a significant amount of car rides, not just the two miles run down to the store to get some milk or to get some cereal or to get some coffee, but a much heavier load on these things. Yeah, it's very, very interesting. So if we look to Europe, the e-bike started as a replacement for bicycle trips in kind of urban environments for people who are maybe getting older or whatever. And the bike, and an e-bike works really well for just intercity transportation. There's been an interesting kind of development in Europe in the last, say, four or five years, which is the rise of the speed electric bike. You can, with a very small battery, you can ride 40 to 60 miles. 40 to 60 miles. Yeah. And that means that you can ride from one city to another. So now what we're seeing is across the Netherlands, actual bicycle superhighways that cover maybe, you know, five to 20 miles, and that becomes a reasonable bicycle ride on the daily basis. And that's really exciting. It's something that is unlike basically any other form of transportation. It's not a motorcycle. It's not that heavy duty. You don't need a license or insurance or anything like that. You're still getting exercise and you're getting where you need to go. Right. So let's talk about the speed because the speed is an interesting thing and I think the speed is what dictates some of the regulations. So we see in San Francisco got inundated with the Lyme scooters and there's boosted boards and one-wheels and all sorts of kind of contraptions with these great high capacity batteries and these itty-bitty little motors. So the form factors are numerous but all of them seem to be gated around 20 miles an hour, which I think is the regulation to keep them from being considered a scooter, you know, internal combustion scooter. So you're talking about speed bikes. So they've got bikes here today that one goes like 28 miles an hour. So how are the regulations keeping up with a bike that goes 28 miles an hour? So it's developing slowly. It's developing based on models that have already been tested and used in Europe. In California, there was actually a model legislation passed, I think three years ago. Which defined three types of electric bikes and defines them as bicycles. So type one is a bicycle that goes to 20 miles an hour and basically you have to be pedaling. Type two is a bicycle that also goes to 20 miles an hour but can have a throttle. Now this is a very Asian type of electric bike. It's not quite as polished but usually they're lower cost. And then type three is this 27 mile an hour type. Still a bicycle, you're required to wear a helmet. And there are some places that you're not allowed to ride them like on shared pedestrian paths. And so what's good about this is it's creating a model for different local and regional governments to create rules. It's taking time. But what's exciting is that there is a model. So the scooters and the one wheels are all operating under kind of this DMV law that is kind of type one. It is kind of type one but it's also kind of like it seems really unclear. I think there's an opportunity in electric bikes for it to be very clear. And I think we're on the way to that. It's just going to take some time. Now in terms of the actual utility, obviously this is a Dutch company. They don't have great weather in Holland as we know. San Francisco as you mentioned is a rugged place. Not to mention the fact it's about as rough as it gets for parked cars getting broken into. So what do you see from your customers in terms of the actual utility? Carrying stuff home from the store, survivability in the streets, not getting stolen. I mean these are not inexpensive pieces of gear. So what's kind of the experience you've seen with your kind of long history in this space in the city? So what I've seen is that what you use matters a lot. So the type of bike that you choose out of the gate is going to dictate first of all how well it's going to last. And second of all, how well it's going to work in the first place. The other thing is that the way, it's not only the bicycle. You also have to have the right lock and you have to have the right bag and the right setup to give you the actual full utility potential of the bicycle. And that's where specialists and retailers really come in. You also need service. So most people have owned bicycles in their lifetime and have maybe stretched one train. Stretching a chain takes about 2,000 miles on a bike. An e-bike rider usually stretches a train in a little under a year because suddenly your bicycle is your preferred mode of transportation for thousands of miles of errands and urban duties and pleasure that you never had before on a bicycle. So it's a switch in terms of how people understand the maintenance that they need on their bike but also what kind of tools they need. Like a great lock. And it turns out that you actually can lock a bike safely. Not overnight on the street, but at any time of day, there are locks that work really, really well to keep a bike safe. So next thing on touch basis is kind of the evolving technology. So we're hearing over and over that really the battery technology is getting this just huge boost from autonomous cars because now there's huge investments in battery. You've probably seen tremendous developments both in the batteries and the propulsion systems and the technology in these bikes since you've been at this for eight years. How's that kind of changing? And how's that opening up, maybe the opportunity to people that maybe didn't want a shorter range, a six, a 10, a 12, a 15, wherever the older kind of range models were. Battery technology that originated in laptops and now is being used in cars and autonomous vehicles totally changed the potential for electric bikes and it changes, it will change so many things about your bicycle. For example, not too far down the road, I believe that there will be anti-theft devices on every electric bicycle that you buy.  So when you put a battery on a bike, it changes everything about what it can do. Right now it's assist, in the future it will be many things. There was this switch about eight years ago from old, very heavy, very polluting batteries to lithium ion batteries. And it means that you can have a bicycle that is, that you can lift, you know, that weighs between maybe 35 and 60 pounds that will take you anywhere from 25 to 100 miles. And that's a game changer.  Integrating activity into your life can change your life in all sorts of ways. It can reduce stress. The funniest one was this guy came in, this family had had a baby like six months ago.  She's a much happier woman now. So I mean all sorts of things happen. People love their bikes. What surprises them I think the most, most often is just how many miles they're accruing on their odometer. And that makes them excited from a health standpoint, from an environmental standpoint. And just from a joy in your daily life standpoint, when we all live with a lot of stress and a lot of multitasking and taking 20 minutes on your bike and just having a great relaxing time is unbeatable. Right. Well thanks for, Karin, take it a few minutes and sharing the story and nothing but success for the store. Thank you very much. All right, she's Karin, I'm Jeff. Thanks for watching theCUBE we're at the Royal Dutch Gazelle bike event outside of Interbike in Reno, Nevada. Thanks for watching.


Coming up on D T N S Windows 11 acts like old Microsoft when it comes to browsers. Way most trucking arm expands on the I 10 corridor and why Blackberry became an example of bad corporate security instincts. D T N S starts now. This is the Daily Tech News for Wednesday, August 18th, 2021 in Los Angeles. I'm Tom Merritt in wet Salt Lake City. I'm Scott Johnson. And in drizzly Southern California. I'm Roger James shows producer. We were just talking about old timey TV shows and why they didn't have a narrative arc. If you'd like that wider conversation become a member. Get our expanded show Good Day Internet at patreon.com slash D T N S where you can join our top patrons like Eric Holm, Carmine Bailey, John and Becky Johnston. Let's start with a few tech things you should know. Two stories released to Apple's security policies today. One Germany Digital Agenda Committee Chief Manuel Hoferlin wrote a letter to Apple CEO Tim Cook asking the company to reconsider its CSAM filtering plans. Also Apple has appealed a copyright decision at loss to Corellium, which makes simulated iPhone software that security researchers and others may use to examine how the devices function. Apple makes a version of its software available to security researchers, but it is more restricted than what Corellium offers. Apple settled most of the claims with Corellium out of court. Now on to Intel, they're planning to shut down its real sense computer vision division and an effort to focus on its core chip business. Real senses portfolio includes stereoscopic, lidar and coated light cameras across various form factors. Intel said it will continue to meet commitments already made to existing real sense customers. Apple announced its share play feature will not ship with the initial release of iOS 15. It's been disabled in the iOS developer beta six company made a shareplay development profile available for devs to keep working on integration. This is the one where you can watch something along with somebody else on FaceTime. Company plans to release the feature in a software update later this fall. Nikkei Asia's sources say the surge in COVID-19 has slowed down Apple, Google and Amazon shift to production from China to Vietnam. Google Pixel 6 and Apple's latest AirPods and upcoming MacBooks were reportedly intended to shift to Vietnam for production. Smart Home products from Amazon recently shifted to Vietnam as well and have also faced delays due to a surge in cases of the virus. T-Mobile confirmed 7.8 million current users and more than 40 million past or prospective customers who applied for credit had information stolen in a data leak. This data included names, date of birth, drivers license and social security numbers. It did not include phone numbers, account numbers, pins or passwords. However, a different leak included 850,000 prepaid customers. And that one did include pins and those pins have since been reset. The company is offering impacted parties two years of identity protection services. Wow, it's pretty good. Alright, let's talk about trucking. Yeah, let's do it. Let's do it. I got way more info about Waymo's autonomous trucking arm. By the way, this is not an arm that hangs out of the side of your truck. We're talking about that part of their business. Waymo via it's called. It's building a trucking hub in partnership with RIDAR in Dallas, Texas. The company has been testing its Waymo driver platform on class eight trucks with companies like JB Hunt on Interstate 45 between Houston and Fort Worth down there in Texas. The new hub that is building or that it's building will help Waymo via expand operations beyond I-45 onto I-10, I-20 and connect with Waymo's Phoenix operations. I am telling you the day that I went and saw Logan in movie theaters and I saw those autonomous driving trucks. I thought that is a reality. I can get my head around and Tom we're finally heading toward Logan town. Yeah, blow the horn. I think I think Waymo via may be the more commercially viable part of Waymo before its passenger car services, even though they're offering commercial passenger car service in Phoenix, it's very limited. It has not been expanding. It's even been some scuttlebutt that some of the engineers are leaving Waymo on the vehicle side. But Waymo via seems to be trucking along real strong here and that seems to be industry wide. We are seeing trucking logistics oriented autonomous vehicles leading the way in commercial viability. This indicates I mean the partnership with Ryder is smart. Ryder's got a huge fleet. And so part of this will be fleet maintenance and making sure that the trucks are good. And as they are able to ramp up autonomous trucks, they'll just go right into that fleet. You still need some humans on board. So they'll be able to draw from that pool because these are not level five autonomous trucks. In fact, I think it's with Daimler that Waymo via is investigating level four autonomous trucks. Level four means you still need some human supervision. They and they have to be on predetermined routes.  But when you're talking about trucks, you stick them on a controlled access highway like the interstate system in the United States. And they do really well. And it's more efficient. Does seem like I mean, it's not quite as the cry crow flies when you're talking about these routes. But it is make a lot more sense than an average driver who's just in a car and how many stops they might make and how many random decisions they might have to make. This is just loaded up and send it. So for now people in there until we get to a further certification. But my question is, should that industry start worrying about, you know, job loss? This is one of those questions that always comes up. I tended to lean into the idea that oftentimes we don't see it right away. But these kinds of innovations lead to other and better jobs, maybe even in the same industry, maybe to support these new initiatives, whatever. But, you know, it's easy to look at this if you're a driver or otherwise involved in that industry and go, Great, computers are going to take over the freight business. What are we going to do? Well, this is one of those industries that's worth paying attention to because in general, people overreact to automation. Automation doesn't necessarily lead to job loss.  It meant that you could now hire those same people for other jobs and provide services that you couldn't before. Ideally, we will see improved customer service because companies who cheap out on customer service won't have to because they'll be saving all this money on automation. However, in trucking, you don't have as much of a clear path to transferable skills. So eventually when you're like, Yeah, these trucks can drive themselves, they don't even need a person on board. A truck driver can't go like, Oh, well, so I've got an obvious place to go and now provide benefit to the company that they couldn't afford before. So that that is something to get ahead of now as this ramps up is like, how are you going to help truck drivers transition to other jobs? The other jobs will be there. But they may require some retraining, they may require some skills that this this could be an area where that where it has a bigger impact, I think. All right, time for another China crackdown update. 10 cents we chat was listed in a government notice Wednesday. The government of China accused 43 apps of illegally transferring contact lists and location data. We chat, of course, a super app in China used for everything. That's a big one. Alibaba's e-reader was on this list. iQiyi was also on this list. That's a video service. The apps have until August 25th to fix the issues. China is set to pass its new data privacy law this week. This is China's version of the GDPR, although with more provisions for government access, whereas the GDPR usually applies to governments and private companies. Tuesday, the government issued new draft guidelines on anti competitive practices that forbid blocking of competitors products from platforms, forbids paying cash for fake reviews and forbids taking competitor data and more. This is very similar to other anti competitive rules being considered in other parts of the world. China's President Xi also announced Tuesday that he encourages, quote, high income individuals and businesses to do more to repay society. This is where you need a little Kremlin ology or Politburo ology or whatever you call it in China, which people are taking this to mean, hey, big tech bigwigs making a lot of money, you need to just come up with things to do to keep me from coming at you. Still, 10 cent posted a 29% rise in Q2 profit. It's gaming revenue, which is under fire, slowed a little. Also, I think people are just not gaming as much as they tended to go back out after lockdowns. But fintech picked up the slack. 10 cent doubled its overseas revenue in 2020 to 7% of total sales, still small, but that may be a pathway forward for 10 cent is to do a lot more overseas. In the earnings call 10 cent President Martin Lau warned investors to expect more regulations from China. But noted that quote, regulation of the internet is a global trend and it's not just limited to China. It's actually happening in the US in Europe. But China is really a bit ahead in terms of the execution of the more structural regulation framework first in regulation. Martin Lau is like China China. Lau also said from our understanding, the government actually wants to foster a long term sustainable development of the internet industry. Basically, I read that to mean like, Dear government, look at us, we're going to be a team player. Lau also said our attitude during this wave of regulation, we want to embrace this environment fully and we want to establish ourselves as fully compliant, please. Also good news for Baidu. You may think of Baidu as like the big search engine in China, which it is. But Baidu is trying to change that perception a little bit announcing a second generation AI chip, the Kunlun two can be used for autonomous driving and has entered mass production. That's music to President Xi's ear, because that's what he wants people to do, shift a little at that energy off the social platforms on the hardware start making some chips domestically. Baidu also showed off a concept Robo car and redesigned its taxi app with ambitions of making autonomous taxis available commercially in some cities within the next couple years. Baidu also announced four new products with its smart voice assistant in them, including a smart screen and TV. So Baidu has got the message like, Yeah, we have a platform the search engine. Sure. But look at all the hardware we're making. We're making chips domestically like trying to win points. Yeah, I kind of when you mentioned this earlier in prep and even again here. That's my biggest takeaway here is it feels like they don't think they're well they meaning the government don't necessarily think sustainability and strength comes in the form of tech talk came up or is over here and all these social services and we got huge gaming companies and these services and internet sort of social networks are not the long game. The long game is a little bit more traditional. If you think about it, it's us making actual stuff that the rest of the world is going to want that we're going to want and will make us, you know, more viable everywhere. And I think that's probably probably true. We can have all kinds of conversations and arguments about how they get there. And if this regulation is actually healthy in the long run or or whatever, there's a lot of, you know, political stuff around that as well. But at the end of the day, I think I kind of agree with this idea of you can't it can't all just be is everyone using us to search? Is everybody using us to post their videos? And is everybody using us to talk to each other? Those are cool. And I think you can still have those and they certainly already do in a very major way. But if I were them, if I were any government, I would try to push toward, I don't know, a more hardware based actual tangible based sort of change to that kind of, you know, the technology space in my country. So I don't know, it's hard to argue with. Let me argue with it then. Because the problem is, that's not where the demand is. And there are lots of companies who do it way better than you. China is not really expecting to market to the rest of the world. They love that. But first, they'd like self sufficiency, they, they would like Huawei to be able to build a Huawei phone without having to rely on the United States. And they've got years to go before that happens. Usually, you let the market decide, even China lets the market decide in technology, where the money should go. What President Xi is doing now is really worrying investors worldwide investors in Chinese companies, because he's saying, I'm not going to let the market decide anymore. I'm going to decide. And I'm going to decide that they spend money on something that the investors have thought others do better. And that has investors really getting cold saying like, Okay, so you're hurting the business that's doing well, and you want them to pour money into the business that they haven't been competitive in doesn't sound like a good business plan. To me, I think I'll drop my stock and you've seen stock even with these good revenue numbers dropping for a lot of these Chinese companies because of that. Well, it'll be interesting to pay attention to that one. You'll follow all of that stuff right on this show. All right, let's talk about BlackBerry, you know, the phones, remember them? Well, it's not really phones anymore. They're now a security and industrial software company. They announced Tuesday, the discovery of battle lock vulnerability in its QNX operating system. QNX is using cars, factory machinery, medical devices. You could even find this stuff on the International Space Station, which is pretty cool. Other companies like Microsoft announced and patched the battle lock vulnerability in May. So you might ask yourself why did it take BlackBerry so long to address this thing? Well, political sources say BlackBerry initially denied battle locks affected or that it did affect QNX, although US Cyber Security and Infrastructure Security Agency or CISA believed it did. So when CISA finally convinced them BlackBerry, they created a patch like you think they might, but said it preferred to reach out to customers privately to warn them of the flaw rather than make a public announcement. Except BlackBerry also admitted it didn't have a complete list of everybody that used QNX because BlackBerry licenses QNX to be included in products that it doesn't necessarily sell or doesn't sell at all. Political says CISA has had to create a PowerPoint to explain to BlackBerry what might happen if they didn't publicly tell everybody about this vulnerability. And the head of CISA Cyber Division, Eric Goldstein said this, while we are not aware of any active exploitation, we encourage users of QNX to review the advisory BlackBerry put out today and implement mitigation measures, including patching systems as quickly as possible, unquote, he did not comment on BlackBerry's delay in the announcement. Boy, yeah. So I could feel the anger already of several people in the audience against BlackBerry. But before you tar BlackBerry with your brush, keep in mind that there goes so many other companies that you don't hear about all the time because they didn't have CISA on their back because the security vulnerability wasn't as high profile. This this is high profile because QNX is in everything. It's an embedded system. It's in ATMs. It's in factory controlling. And that's why BlackBerry didn't have a comprehensive list of who's using it because BlackBerry provides QNX to other OEMs who make products. And BlackBerry doesn't have their customer lists. It just knows like, oh yeah, we they pay us for using QNX. So what was going on here is the old fashioned way of thinking of like, well, we don't want the bad guys to know the vulnerability is out there, except that it was revealed in May that it's out there. So even though you didn't say it was in QNX, then the bad guys were looking at QNX to see if it also was there. That never works. Usually the bad guys will find it anyway. Second was we didn't want the embarrassment, you know, we wanted to go privately to our clients say, hey, you need to fix this, but we don't want the blowback because we're a security company and we don't want to look bad. Those days are over. Every company has these things and what makes you look bad is not confronting it. The modern way, the 2021 way is to go like, hey, good news, we found a vulnerability. Here's how to fix it. We don't think it's actively exploited. Everybody get on it. Okay, good job team. We found the vulnerability, which is what Microsoft and others did back in May. So this is, it's not good news in that it's BlackBerry not moving with the times and an acting old fashioned, but they're not the only ones. It's a corporate culture thing that really just needs to be stamped out. It's probably worth mentioning too that, you know, there is a mindset. If this was, if you told me this company was Technotronics Incorporated LLC.com or whatever, and they have this vulnerability, I'd go, oh, interesting. Okay, well, it sounds like everyone's on it. They're gonna have to deal with it and ceases all over them and all this. But because it's BlackBerry, our brains go, gink, it's BlackBerry and it's fun to hate on them because they sure, boy, they sure have just screwed up back in the day and now look at them screwing up again. Like there's a little bit of that mentality going on and it's hard to avoid. But yeah. Well, folks, if you try to hide the BlackBerry patch, you end up in a thorny situation. All next week is DTNS Experiment Week. While much of the world vacations in the summer, we're swapping out our normal DTNS show and trying out some new show ideas hosted by DTNS producers and contributors. So instead of just taking the show down for a summer vacation, we're going to give you a Chris Ashley barbecue tech show, a Jen Cutter state of video gaming, Rob Dunwood with the second look at tech, Rich Strothalino's Ask a Luddite and a few more. It all starts next week, Monday, August 23rd, right here on the DTNS Feeds. This story is going to make you feel like it's 1999. Windows 11 is changing how users manage the default browser. When you install a new browser, the first time you click on a link, you'll still be given a choice to select a browser and always use this app. That hasn't changed from Windows 10. However, here's what has changed. If a browser prompts you to make it the default or you just plunge into the settings yourself, things will be more complicated.  One of those categories is web and under web you can choose from any installed browser or look for an app in the Microsoft Store. Pretty simple. Here's one downside to consider. When you choose that as the default, it doesn't change the setting for all extensions, just most of them. Remember that. Keep that in mind because that goes partway to explaining why Microsoft is doing this. In Windows 11, the categories are gone. When you go into default settings, it doesn't say email, web, etc. Instead, you choose an app. It's a list of apps and you can search, choose an app and then go in and assign that app to defaults by extension type. For browsers, you're given multiple options. HTML, HTML, HTML, PDF, SHTML, SVG, WebP, XHT, XHTML, FTP, HTTP and HTTPS. So if you want to change your default browser from settings, you have to make that a browser the default for each type.  It's fast, secure and built for Windows 11. You're going to get nagged. Microsoft describes this as giving customers control of defaults. A Microsoft spokesperson told the Verge it's meant to let users quote, customize and control defaults at a more granular level, eliminating app categories and elevating all apps to the forefront of the defaults experience. And granted, our technical pointed out, SHTML not handled in Windows 10 when you changed the default web app. So this is giving you that control right up front. The Verge's Tom Warren found that Firefox is already adapted to this. And so when you go into Firefox and say, make this the default browser, it handles it for you without you having to go into the default app settings. But none of the other browsers have done that yet.  Windows 10 already ignored the default browser in search and the taskbar widget. And Windows 11 ignores the default browser choice in all widgets and search, sending all users to Microsoft Edge for those. So a lot of people frustrated, Scott, about this one. Yeah, my first feeling is okay, I'd like, I like my extensions to be proper, you know, to work well, whatever that may mean. If I install something new on a computer, and it just kind of knows, well, I should be the the king of your PDFs now. I kind of like that. I don't have to dink with it. I kind of know I installed it for that reason. And it's going to work. And if I want to go change it, I can I can change, you know, where things go. Now this is a lot of extensions. They're all web, not all, but they're very web centric extensions. Right. And chances are, I'd kind of like an all or not. Let me be granular. They can go fine. Yeah. Let me have a switch that says I would like all of these to default to Firefox or Chrome or whatever it is I'm choosing or all of them to Edge. That's why I don't necessarily buy their whole we're giving you more power and more tools and more whatever you're giving us more busy work if we truly want to like avoid Edge and use something else. I happen to think Edge is pretty good right now in a decent choice for desktop operating system or a desktop browser solution. That aside, I don't like this feeling of like, well, it's sort of all set for that now. But if you want to use something else, you better come in here and really noodle around on the details. I think you're asking a lot of people. Remember, Microsoft is not a person. There's not Bob Microsoft that sat down and made this policy. Microsoft is a lot of people are their employees of Microsoft who feel like, you know what? The more we can nudge people to use Edge, the better and maybe they'll get frustrated. But whatever. Yes, they're likely are. But there are also engineers who thought this literally like I believe thought like, no, this is better. Give them give people control over this. Let's put it in the beta, see how it works and we can adjust from there. So hopefully what happens is those engineers rule the day, uh, and they are able to hear Scott and go like, Oh, you just want to select all. Yeah, great. Yeah, we can put that in there or make it even easier. Bring back the categories and let me say I'll let you handle it or I'll click here to customize, which granted is more like what Windows 10 was doing. So maybe they don't want to do that.  If your idea was like, we put it out there to hear what people think and will adjust, adjust. There's a lots of us who don't like this and want an easier way to set a default browser. Yeah, right. I agree. And there may not be a Bob Microsoft, but there is a Microsoft Bob.  Take it away. Hi, this is Nika Montford of the snobbo West show back with another episode of Teching While Black. In this segment, I bring awareness to an innovative black leader in technology. This week's spotlight is on Vanessa White, the first black woman to lead a NASA center. She will serve as the 13th director of the Johnson Space Center, where she will spear head space flight missions, the International Space Station mission operations and the Orion program. A native of South Carolina, she earned a bachelor of science in materials engineering and a master of science in bio engineering from Clemson University. No stranger to the NASA community. She is a 30 year veteran of NASA. She began her career at NASA in 1989 as an engineer who managed several space shuttle missions among numerous prestigious awards, which she's earned to NASA outstanding leadership medals and to NASA achievement medals are both in the rank. As I've said many times before, history is truly being made in real time every single day. So today we celebrate Vanessa White in the here and now. To find out more about her and her work, you can follow her on Twitter at the underscore White. Join me next time as I highlight another black tech innovator. When we are aware of all innovative voices, especially those in underrepresented groups, the tech community thrives. Thank you, Nika. Oh, Vanessa White is impressive. I've been to Johnson Space Center before. You have. Yeah. Did you think of me when you were there? Well, I hadn't met you yet. But I do now. But I think fusion energy is an area of intense research because it involves creating energy from pushing atoms together rather than splitting them apart. That results in much less of a chance for explosions and less toxic waste. It's generally quite a bit safer and better for the environment than nuclear fission. We confuse atoms all day long. That part isn't a problem. The big barrier is ignition, basically getting a reaction that sustains itself and produces more energy than you put into it. Science magazine reports that scientists of Lawrence Livermore National Laboratory aimed 192 laser beams at a sphere of deuterium and tritium housed in a gold cylinder. The shots vaporized the gold, which produced x-rays that imploded the capsule and sparked a sustained fusion reaction for 20 nanoseconds. Yeah, not terribly long, but hey, we did better than we've ever done. And they put in 1.9 megajoules to make it happen and got out 1.35. So about 70%. They didn't get more out yet than they put in. But before you start razzing Lawrence Livermore lab, that's eight times better than the lab had managed before. And it puts them much closer to achieving full ignition. Of course, there's a matter of how you sustain it for more than 20 nanoseconds and all of that to follow. But hey, getting closer, right? Yeah, that's awesome. I think that's super cool. I feel like you and I since maybe our high school years have been told that cold fusions on its way, we're going to find a way to do this is all going to happen. And this is as close as we've got. And hey, if you got to vaporize a little gold once in a while, what's the harm? Yeah, this is hot fusion, by the way. This is not called this cold fusion. But yeah, cold. Remember that it was like the great it was like coffee cup. Yeah, it's never going to happen. That was around the time I went to the Johnson space letter. All right, let's check out the mail bag. Nathaniel in Salkum says, hey, folks, first off, you're doing a great job on the show. Thank you, Nathaniel. I'm looking to buy my first 3d printer, and I realized been a while since I've heard anything on DTNS on this topic. How about a roundup of where things are in the industry and a look at where the tech was a few years ago and where it could go next. Also looking forward to the great August experimental week. Nathaniel, thank you. I'm glad to look forward to experiment week. This is a great question. 3d printers have not been in the tech news and I have a few reasons why I think that is a lot of the 3d printing investment and innovation is happening at the industrial level. So you're getting a lot of like 3d printing food, 3d printing industrial parts that's happening, and it's not at the consumer level that you can buy. And while we do touch on industrial and enterprise on the show, our focus is consumer. But it's been a long time, Scott, since we've talked about a consumer level 3d printer product that caught everybody's attention. Yeah, and certainly it has, you know, it's probably got its fandoms larger than it's ever been, but you don't hear about it as much to think for the reasons you mentioned. But also, I think this is actually a good sign. This is a sign that we are maturing in that space. And when it starts happening, or the big money is spent on the more of the corporate level or we're printing 3d rockets or whatever it is, people are printing at that level and they're using titanium and steel and other crazy materials.  This is true of almost anything kind of starts huge giant mainframe computers. Now you're walking around with a phone in your pocket. Sometimes it takes a long time, but this feels like progress to me and it doesn't mean that there aren't amazing things happening in the creator community or otherwise with personal 3d printers. It's just that we're now past that stage of this is a weird anomaly that only three people in the whole neighborhood have and now we're to this place where. Oh my gosh, this entire restaurant was prefab by a 3d printer. I can't believe it like that. That's progress. We're moving. There was a time late 80s early 90s where personal computers faded away. There were there was a lot of enthusiasm for it in the early mid 80s. Personal computers kind of faded away and everybody thought of personal computers as a business thing. Now you do that of a business.  And it wasn't until the late 90s, mostly with the Internet that everybody started needing a computer and people like, oh, well, maybe I do need one at home, even if I'm not Bob business. So I don't know why everybody's Bob today. That's just so I think 3d printing is kind of in that same stage where there was a lot of enthusiasm, a lot of press around, look what you can do in your home for an affordable amount. Now there's all the people who were using amigas, the analog of them using 3d printers, you just don't hear about as much. You know, we know someone who's in this business, maybe we can reach out and get them on. But if anybody is in there themselves and an expert on it or knows a great expert to talk to email us feedback at daily technewshow.com.

Hi and welcome to the session. Let us discuss the following question which is let A be the matrix of order 3 by 3 with the elements 3, 2, 5, 4, 1, 3, 0, 6, 7, express A as some of 2 matrices such that one is symmetric and the other is skew symmetric. Now before moving on to the solution let's recall what is a symmetric and skew symmetric matrix. Any square matrix A is said to be symmetric if A transpose is equal to A and any square matrix A is said to be skew symmetric if A transpose is equal to minus A. Now let us also recall an important theorem which will be very helpful for this question that is for any square matrix A with real number entries A plus A transpose is a symmetric matrix A minus A transpose is a skew symmetric matrix. This is the key idea for this question. Now let's see its solution. We are given a matrix A of order 3 by 3 with elements 3, 2, 5, 4, 1, 3, 0, 6, 7. So first of all we will find out A transpose. Now transpose of a matrix is obtained by interchanging the rows and columns of that matrix. So here A transpose will be a matrix of order 3 by 3 with elements 3, 4, 0, 2, 1, 6, 5, 3, 7.   Thus we can express A as a sum of symmetric and skew symmetric matrix. So that means here we need to find two matrices that is the matrix P which is equal to 1 by 2 into A plus A transpose and matrix Q which is given by 1 by 2 into A minus A transpose. So first of all let us find out A plus A transpose which will be equal to the matrix A that is the matrix of order 3 by 3 with elements 3, 2, 5, 4, 1, 3, 0, 6, 7 plus the matrix A transpose with elements 3, 4, 0, 2, 1, 6, 5, 3, 7. Now we know that to add two matrices we are there corresponding elements. So this will be equal to the matrix of order 3 by 3 with elements 3 plus 3 that is 6, 2 plus 4 that is 6, 5 plus 0 that is 5, 4 plus 2, 6, 1 plus 1, 2, 3 plus 6, 9, 0 plus 5, 5, 6 plus 3, 9 and lastly 7 plus 7 that is 14. Now the matrix P is given by 1 by 2 into A plus A transpose. So the matrix P will be equal to 1 by 2 into A plus A transpose that is the matrix of order 3 by 3 with elements 6, 6, 5, 6, 2, 9, 5, 9, 14 and to multiply a matrix with a scalar we multiply each element of that matrix by the scalar that is 1 by 2. So here we will get the matrix of order 3 by 3 with elements 3, 3, 5 by 2, 3, 1, 9 by 2, 5 by 2, 9 by 2 and 7. Now let us check whether the matrix P is symmetric or not. So let us find out P transpose which will be a matrix of order 3 by 3 with elements 3, 3, 5 by 2, 3, 1, 9 by 2, 5 by 2, 9 by 2, 7 which is equal to the matrix P itself. Thus here the matrix P is a symmetric matrix. Now let us find out the matrix A minus A transpose. So here this will be equal to the matrix A that is the matrix of order 3 by 3 with elements 3, 2, 5, 4, 1, 3, 0, 6, 7 minus A transpose that is the matrix of order 3 by 3 with elements 3, 4, 0, 2, 1, 6, 5, 3, 7. Now here we will subtract each element of matrix A transpose from the corresponding elements of matrix A and thus this will be equal to the matrix of order 3 by 3 with elements 3 minus 3 that is 0, 2 minus 4, minus 2, 5 minus 0, 5, 4 minus 2, 2, 1 minus 1, 0, 3 minus 6, minus 3, 0 minus 5, minus 5, 6 minus 3, 3 and 7 minus 7, 0. Now the matrix Q is given by 1 by 2 into A minus A transpose. So let us find out the matrix Q which is equal to 1 by 2 into the matrix A minus A transpose which is this one. So Q will be equal to 1 by 2 into the matrix of order 3 by 3 with elements 0, minus 2, 5, 2, 0, minus 3, minus 5, 3, 0. And here also we will multiply each element of this matrix by the scalar 1 by 2. So this will be equal to the matrix of order 3 by 3 with elements 0, minus 1, 5 by 2, 1, 0, minus 3 by 2, minus 5 by 2, 3 by 2, 0. Now let us take whether Q is this Q symmetric matrix or not. So let us find Q transpose which will be given by the matrix of order 3 by 3 with elements 0, 1, minus 5 by 2, minus 1, 0, 3 by 2, 5 by 2, minus 3 by 2, 0 which is equal to minus Q thus Q is a Q symmetric matrix. Now let us find the matrix given by P plus Q. So this will be the matrix of order 3 by 3 with elements 3, 3, 5 by 2, 3, 1, 9 by 2, 5 by 2, 9 by 2 and 7 plus the matrix of order 3 by 3 with elements 0, minus 1, 5 by 2, 1, 0, minus 3 by 2, minus 5 by 2, 3 by 2 and 0. And this will be equal to the matrix of order 3 by 3 with elements 3 plus 0, 3, 3 plus minus 1, 2, 5 by 2 plus 5 by 2 that is 5, 3 plus 1, 4, 1 plus 0, 1, 9 by 2 plus minus 3 by 2 that is 3, 5 by 2 plus minus 5 by 2, 0, 9 by 2 plus 3 by 2 that is 6, 7 plus 0, 7 which is equal to the matrix A thus the matrix A can be expressed as the matrix of order 3 by 3 with elements 3, 3, 5 by 2, 3, 1, 9 by 2, 5 by 2, 9 by 2, 7 plus 3 by 3 with elements 0, minus 1, 5 by 2, 1, 0, minus 3 by 2, minus 5 by 2, 3 by 2, 0 where this is a symmetric matrix and this is a skew symmetric matrix thus we have expressed A as the sum of a symmetric and a skew symmetric matrix. With this we finish this question and the session as well. Hope you must have understood the question. Goodbye, take care and have a nice day.
