to do to do to do to do. The stream don't like this. It's fine, Sarah. It looks good. I know. I know.  You want to spray, spray, spray the show and profile. Let's try it. You can do the entire show like that. It could be a milestone. Sure. It's true. Why not? Camera, if we get to this. No, it's fine. It's fine. It's fine. I was about relaxing. That's right. That's what it is. I was getting all stressed trying to pick a hat earlier. And I was like, you know what? That's not that's not the spirit of half Friday. So I just went and got one of my more comfortable hats. I'm like, I'm just wearing that. Right. Yeah. I I I'm also wearing my most comfortable hat. There you go. What if we just wore like bath robes for the show? The awkward. Go for it, Roger. Yeah. Do you take us off? Do I do the suit coat over the bathroom then? Why not? If that be kitschy or funny or, you know, hefty re hefty re. I don't like my bathroom. Yeah, my bathroom is old. I bought it at Target in tooth. And then 1988. Whoa, dude. My bathroom is that it's like that kind of material that's super plush and soft. And you think like, oh, this is the best. Doesn't breathe like Terry. So I'm like, I don't like wearing this. Mine used to be softer. That's old now. You would think it's older. It gets softer. No, it just gets thinner. It's like the red bear.  Yeah. Is that related to a brown bear? No, this is the bathrobe I bought when I went to college. My sister took me shopping for stuff. Tom, that's amazing. Gosh, no wonder it's the red bear. This is I'm very thrifty that way. This is something Roger and I have in common. Yes, frugal, I think is the flight. Yes, okay. You guys are ready? Yep. Here we go.

This is the Daily Tech News for Friday, December 8th, 2017, from DTNS headquarters in Los Angeles on Tom Merritt. And from Studio Feline, I'm Sarah Lane. And from Sailor Snub Studio, I am Shannon Morse. Sailor Snub's all like that. Roger Chang with us as well deep in the DTNS production basement. It's not a basement. No, in the east wing of our production. The east wing of our map. Let's start with a few tech things you should know. And pardon me, Amazon Echo and the Amazon Music Unlimited Service launched in 28 more countries Friday across South America and Europe. Amazon Music Unlimited is available on its own and works on iOS, Android, the web, Fire TV, PCs and Macs. KGI Securities Ming-Chi Kuo told investors in his most recent note that he believes Apple will bring the iPhone X's L-shaped battery design in a larger size to 6.5 inch and 5.8 inch OLED iPhones next year. Kuo also believes a 6.1 inch LCD phone will come with a regular rectangular battery. iPhone X, huh? You're one of those. Yeah, I'm one of those. Deal with it. That's fine. That's fine. I'm not judging. I'm an Android or OK. Just something to... You're not the only one, Shannon. Yeah, no. I'm not the only one. The Weekly Standard has joined Facebook's fact-checking initiative as well as joining the pointer international fact-checking network. Facebook's fact-checking system, if you remember, adds labels to news items found to be false by members of its fact-checking partnership. Now, let's move on to some top stories. Start with you, Shannon and Vidya. Whoo! Yeah, and Vidya announced the Titan V video card for machine learning. The Titan V features 110 teraflops, nine times that of the Titan X. Titan V will also get access to the Nvidia GPU cloud containers with optimized versions of popular machine learning development frameworks. The Titan V is available today for $2,999, three grand. I'll be picking up none of those. Yeah, totally. But they're not meant for me. They're meant for serious machine learning. So, people use these for Bitcoin mining, too. Yeah, Bitcoin mining would be great. And it's a big advance. It's funny to think that when Nvidia first started making these kinds of cards, it was like, wow, Nvidia really changing tactics, getting serious about high-level machine learning and business uses. Now it's just run-of-the-mill. It's DeRugura. Nvidia is the people who make your video game necessary gaming card, but also these kinds of chips that are essential for artificial intelligence, machine learning, et cetera. Sources tell Bloomberg that YouTube plans to launch a paid music service called Remix in March. The sources say that Warner Music has already signed on and talks are underway with Sony, Universal, and Merlin. Google introduced Google Play Music in 2011. Then YouTube Music Key in 2014, which became part of YouTube Red in 2016. I'm starting to lose track of all the YouTube paid offering. I am, too. Yeah, I've seen so many from them. I'm like, okay.  So, I'm wondering, is this Remix service going to be the same way, or is it going to be entirely similar? Further standalone, maybe, if for some reason. You know, I wonder, the whole idea of YouTube Red, I felt like was this initially, right? Yes, right? It was the premium YouTube with actual partners of networks that people know and would watch on TV. But perhaps this is some less bundled into Google Play Music offering that they feel a lot of people might want to buy. One would assume that they struck deals with the labels for Google Play Music. That's the thing. And then apparently struck them again for YouTube Music Key, and now are striking them a third time. But maybe what I'm hoping, not maybe what I'm hoping, is that maybe what they're doing is consolidating and saying, you know what, we're going to take Google Play Music, we're going to take Music Key, and we're going to put it in this new thing called Remix. That would make sense called Remix because you're remixing all of your services and simplify it because I really like Google Play Music. And as long as they don't lose those main features that I like, one of them is being able to store my own MP3s that I get from like little indie places that just aren't available from Spotify and Apple Music. I'm going to be cool with that. So either, I guess, don't get rid of it or make it better.  It's a little, it's kind of a funny name. But if it is actually YouTube saying we've remixed all of our paid offerings into this better one with more partners than ever, then maybe it makes more sense. It just makes me hear someone yelling, Remix. Me too, like scratching the record a few times. Yeah. Stories to tell writers that Didi Xuxing, the ride hailing service that is very popular in China, they bought Uber's service there. Plans to offer its ride hailing service in Mexico next year. This would be its first operation outside China. Something I've been keeping an eye on is, when are these big Chinese companies going to successfully make a move outside of their home territories? Some are, some are more successful than others at this, but nobody's really gone whole hog other than say Lenovo and Huawei maybe. So this would be one that's not a cell phone maker. Didi officials met with Pro Mexico, a government trade and investment organization last month. Mexico City is Uber's third largest market after Sao Paulo and Rio, and Cabify is the other big ride hailing service there operating in seven Mexican cities. Mexico City, and I think we were asking just the other day, I mean, that's a huge city. If you're going to run a ride hailing service, it's certainly going to cover a lot of ground there. Sao Paulo and Rio would be two other examples of huge cities where there's a lot of potential for growth. I could easily see Didi move into Brazil next after, let's say they try it in Mexico, it works out. They are partners with Uber in China still, even though they bought Uber service, there's still a residual partnership there. So it would be interesting how that plays out when they're direct competitors in this market. Because I think if you haven't, man, I don't want to say that because I'm not sure, but I know there's some relationships still going on in China. It's good to see this competition in the international market, especially if you're a visitor going to those international markets and maybe Lyft or Uber isn't necessarily available. It's nice to have other ones available too. So moving on, 9to5max says a home kit vulnerability in iOS 11.2 was shown to them which would allow unauthorized access. Apple has rolled out a server side fix that disables remote access to shared users. An update to iOS 11.2 is coming next week that will restore full functionality. The vulnerability only exists in iOS 11.2, not the earlier versions. So other than the information here in the news, we don't really know exactly how this vulnerability works, but that's not surprising given that the update is now rolling out. So we'll probably find out more about it once the fix rolled out. And I'm very curious myself as to what exactly or how exactly this vulnerability works. Yeah, I mean, taking what we do... iOS is really on a roll, aren't they? Yeah, no kidding. Apology, we had just talked about it. We were saying, wow, Apple had a very rare apology and then they patched this fix. It was last week. This time it's like, we'll get to it next week. And then there was that other texting issue that I had trouble with. It's like every week it's something new. I think there's some things we can glean from this too. If they disable remote access to shared users, it would make you think that the vulnerability is somehow an ability to get in and spoof yourself as a shared user if you know certain things about someone's iCloud account, like maybe just email address. You might not even have to hack into it because that's a pretty severe thing to say. You know what? We're just disabling shared users because that's one of the features of having smart locks is like, oh, I can delegate this to my kids and my friends. So the only... It could also be however the shared users, whatever protocol it's using to transmit that information from 0.8.2. So yeah, I'm just curious. I want to know more. I like to know all the details about these security vulnerabilities. Me too. Well, speaking of access, last month Google told Android developers they had 30 days to explain how an app that they put together using the accessibility APIs was actually helping a user with disabilities and not something else like hooking into the operating system without a good reason. And Google said, they can't do that. They're going to be removed from the Play Store. There was a big public outcry, a lot of backlash from app developers who say, well, hold on a second. This isn't necessarily for somebody with a specific accessibility need, but it's also not hurting anybody. So Google now says it is pausing its original decision for another 30 days while it considers, quote, responsible and innovative uses of accessibility services. Man, this is becoming a theme in technology, right? The idea that companies have to make judgment decisions over the uses of their technology. We're most familiar about this with Twitter and Facebook and posting of news or posting of controversial videos. But here again, somebody's saying, well, hold on, you may not think this is helpful to people with accessibility needs, but you're missing something or it's not harmful and it could be helpful to lots of different people. Sure, there was an example of, for example, a battery app which uses hooking into APIs to be able to shut down other apps that are hogging up your personal device, right? So it's about your, it's local stuff that you're doing for yourself, right? If you want a very good performing phone and this app helps, who are you really hurting? So I get it. In this case with the accessibility APIs, I believe LastPass, correct me if I'm wrong, but I believe LastPass was another one of these applications that was using that accessibility API and they quoted, they said that they were working with Google to come up with a fix for this issue since they were going to drop any apps that don't necessarily help with disability problems. So maybe LastPass is one of the reasons why they are pausing it. It would make sense. I think what LastPass does is it uses the API to populate password fields. It does the autofill. So it's like, again, it's like, well, if it's convenient for me, just kind of sex to roll that back again because it's a personal thing. The counter argument is that's not what that API is for. We are not developing it to be secure for that usage. So if you're using it that way and you break something or a vulnerability crops up, that's not something we're paying attention to because we're designing it for this use and that could cause problems. So what maybe Google might want to do is be like, okay, accessibility is one thing and then we'll just like duplicate that call something else and then we just monitor that whole part of the app world in some other way. There's accessibility and cool accessibility.  Well, no, that's really bad. I think that means something else. That professional life, I don't know. Profit, yeah, yeah, gotcha. Come back to me on that one. All right, we'll workshop that one out more.

You can also get it on Google Home through the Anchor app and you can get it on the Anchor app at anchor.fm and that's a look at our top stories. Okay, so we're going to revisit a story that we've touched on before, but Shannon's got some good insight into what people are saying in the community about this. You may recall that Uber announced or revealed recently that they had been breached last year by a 20-year-old from Florida. The breach happened in October 2016. The names and driver license numbers of 600,000 drivers were exposed, U.S. drivers, particularly. Personal info of about 57 million riders was exposed like name, email address, phone, not credit card info, not travel info, but still. The Floridian who was accused of the breach paid a second person for services that involved accessing GitHub to obtain credentials for access to Uber data. Wasn't hacking GitHub. GitHub didn't suffer a breach itself. It was just stuff that was posted there and this guy paid that person to find it. Uber then allegedly paid this Floridian $100,000 through their bug bounty program and got him to agree to destroy the data according to Reuters and supposedly sign an NDA saying he wouldn't tell anybody about it. In the Reuters story, the attacker is said to be living with his mom in a small home trying to pay the bills. One source said Uber didn't want to prosecute an individual who did not appear to pose a further threat so they didn't want to make a big deal about it. Travis Kalanick allegedly knew of this payment and this breach but it is unclear who authorized the actual payment whether it was him or somebody else. Well, November 21st, new Uber CEO, Derek Ozerashahi, revealed this saying none of it should have happened and quote, I will not make excuses for it because Shannon, it's the law. They have to report this stuff. Right, exactly. And there's two major parts about the Uber story that have been floating around in the Infoset community for the past couple of weeks since this new story first broke. And a lot of people were making rumors and stuff but in the Reuters story itself has brought to light a lot more information. So with response to what the CEO said, you're right. It's definitely illegal to not disclose a hack in several different states across the United States and I believe there are five different states who are putting in motions against Uber because it is illegal to not disclose this information within a given timeframe. And I believe those different states have different timeframes for them to release that data. For example, California's is like 60 or 90 days, something around there that you have to disclose a hack before you end up getting sued for not disclosing it. So it's illegal in the first place but it also puts the people who are users and the people that are drivers in harm's way for a longer period of time because they don't know that that hack happened. So how do they know to protect themselves any more than they are already doing? Yeah, they have a right to know that it happened. Now I get what Uber was trying to do. This is classic pre-Cosmer Shahi Uber which is like, oh dude, it's just a guy in Florida. He's sorry, he's not gonna do it again. Let's not ruin his life. We're Uber, we can get away with anything. So we'll just shuttle it through the bug bounty system. Then it's not a breach because anytime someone finds a bug they may expose themselves to personal information like this as part of the breach but they report it responsibly as a breach and say I didn't copy the data, I destroyed any data that may have made it to me and that's what they after the fact sort of made it look like happened. Which is so not what happened. No, that's not what happened at all and we should make clear that responsible disclosure when it comes to hacks and when it comes to vulnerability assessments and finding these things with companies means that you are responsibly going to the company and saying, hey, this information is public. It's out there like anybody can access it. You should probably lock this down. They don't with before they contact the company they don't copy that to their own computer and then go, hey, by the way, this stuff is on your computer. You should lock it down. Like there's no reason for somebody to do that if they're responsibly disclosing it and they want to go through the bug bounty process. So what Uber did by going through hacker one which is the bug bounty company that helps distribute bug bounty money to all these different vulnerability assessors and security researchers. I feel like it's so immoral from an information security professional standpoint. It's very immoral for Uber to do that as a company because if I was like a bad guy hacker I would look at that and be like, ooh, I could do that too. I wonder if I could make $100,000 by saying it's a bug bounty when it's not actually a bug bounty. The line about Uber not wanting to ruin this poor man's life living in a small house with his mother and things very hollow to me as well. It's like, listen, Uber, it's not that it's ever okay for security breaches to happen but it's not as if Uber would be the first really big company with a lot of money and a lot of power in the last couple of years to be embarrassed by something like this, right? So that on its, you know, at face value is that's one issue but the whole kind of cover up about it and then to be like, well, we just didn't want to prosecute this poor person. That's such horse pucky. I, you know, it's like, it's an anonymous source, right? So, you know, we don't exactly know where that came from but that's like such a typical spin of Uber being like, oh, we're friendly. We just didn't, we wanted to be cool but it's like, no, they didn't want to be embarrassed. All right, Kurtle Potter with your horse pucky. I feel the same way and I should say I feel I don't have time to change it from a different word. I feel the same way that Sarah does. We don't have factual evidence saying like, oh, yeah, they didn't want to release this. So they're just wiping their hands and then telling them that, you know, he's got to sign this NDA but if he did in fact sign the NDA and if they did in fact go through the forensic analysis and decide to keep it quiet by not prosecuting him that just means that they were trying to keep it quiet for a year and then eventually the news came out and broke. So we all know about it which makes it so much worse that they waited so long.   Let's make it super sympathetic, right? That doesn't matter. He was able to access this data. And yeah, okay, Uber came in and made him delete it all, right? That doesn't matter. It was there for him to access who else could have also access that didn't tell Uber about it is the question. That's why you disclose these things not because the guy with the sick mother, she's not sick, I don't know. I don't even know if he has a mother. It's not because he was able to access it. It's because it was accessible. Yes. The fact that he did it means someone else could have done it and you need to know that like, hey, we don't know we think we got rid of it all but we don't know for sure. So you should be aware of this. I think this is a great learning experience for other companies because they'll look at Uber who of course Uber has tons of money. They'll be able to deal with all the court costs for all the different states and everything and I'm sure they're going to be sued in whatever courts it might end up being but other companies should look at this and consider the fact that it makes your customer relations so negative from the pure fact that they can't trust you and when it comes to security and privacy especially after this year's development of, you know IoT devices being insecure and everything with Equifax and all those different things. Customers are paying a lot more attention and Uber is not paying attention to their customers when it comes to that.  I found this.  They should be taken to court. It's even if though it's not his fault, it is the company's fault and that's the way it works. Yeah, it is. That's why they have lawyers. Yeah. Well, yeah, and like you say, this is immoral and it should not be seen as a precedent in any way for people to think, you know, go through the bug bounty program. That's what the bug bounty program is for. Do it responsibly. That's the best part of this. It's like, that's why there's a program so that companies can benefit from the intelligence of people outside their organizations that can be like, hey, let me help you put a little bandaid on this issue you got going on. And the whole kind of like under the table part of it is just like, Uber, hide it out. You know, how much do you learn? A lot of those bug bounty programs only pay a few thousand dollars for these kind of vulnerabilities and this hacker basically held it for ransom and got a hundred thousand dollars to keep it quiet. It was basically silencing money. So he got a lot more money for doing something that is immoral and illegal as opposed to going through the correct motions of the bug bounty and getting a few thousand dollars as opposed to a hundred thousand dollars. And my one of my biggest worries here is that other hackers are going to see this and do the same thing. And I really don't want them to. I want more people to be involved with the correct vulnerability disclosures that you're supposed to do with companies. And we could argue with maybe the maybe the bug bounty should be higher or not. But that's the issue here is the company shouldn't respond in the way that Uber respond. Right, right. Exactly. Well, it's it's we can I can think of similarities with lots of other things where issues being settled out of court happens. Oftentimes public is none the wiser. And then we all find out about it later and it looks really bad. At least that follows the legal legal process in those cases, but you're right. It's not that much different. Hey, thanks to everybody who participates in our subreddit. You can submit stories and vote on them at DailyTechNewsShow.Reddit.com and talk about stuff on our Facebook group as well. Facebook.com slash groups slash Daily Tech News show. What's in the mailbag there, Sarah? Well, you know, we we've it's been an interesting week for a lot of us and we've had so much feedback about Patreon changes and just the show in general and what people like and don't like and all that good stuff. We just got a really warm and fuzzy email from Chris who says he's a proud patron of DTNS and I thought we could all use a little holiday chair. So Chris says, regarding the Patreon changes, I know there's still uncertainty and confusion. I really appreciate you letting us know what's going on. Usually the people who are upset or angry, especially on the internet, are the ones who reach out. So I thought it was a good excuse for me to tell you some of the things I appreciate about your show. Daily Show that gives me a lot of interesting and informative content to listen to as I do various mundane tasks in life, love it. Keeping me informed about various tech things going on in the world, love it. An insolvable cast who are able to respectfully disagree. Thank you, Chris, for saying so with each other but actually have real discussions about complex issues that they might not have single or complete solutions. This is one of my favorite things about the show, says Chris says the variety of random discussions pre and post show like that too. And then he also kind of gives Tom a special shout out and says Tom's ability to argue whatever point is gone straight to what someone else is saying is actually my favorite thing about the show. Chris, Chris, Chris believes you have a gift, Tom. Do I though? Do I? Yeah, he says just nice things about us and says that, you know, he listens to the show every day and I will say Chris that it's true. A lot of times people who have issues or criticism or negative feedback are often the loudest or can seem that way when you're soliciting feedback from folks and it was very nice of you to point out the things that you like about the show and we appreciate it and hope other people feel the same way. Yeah, he just raised his Patreon pledge because he says I'm in a financial position to do so and I know the current changes will be costing you some supporters. So we really appreciate that, Chris. Also, he said Tom's ability compulsion to argue.  Yeah, and I'm not going to read this whole other, yeah, probably sometimes. I would, for the record, I would say I don't think that you're just like, and let me be the contrarian every time anyone says anything, but I do think that you go out of your way to try to, you know, got to look at both sides. Yeah, well, sometimes I do go out. No, I'm just kidding. Brandon from Idaho has a great email talking about credit card processing and the intricacies of it. If you're confused about stuff, you really should go read this. He used to work at an HOA. He said, I've researched and pitched payment systems to volunteer boards in the past. And most in my experience, when they see the fees involved, want nothing to do with it. And he talks about how communication strategy is really, you know, one of the fundamental issues with this sort of thing. So, you know, if you want to know a little bit more about that, go check out our show notes, dailytechnewshow.com, read Brandon's email. Thank you, Shannon Morris for joining us. Thank you. Shannon, where can people find out more about everything that you do online and elsewhere? People can find me. I'll pimp my tech thing. It's tekthing.com. We've been doing a lot of reviews lately, and we're going to be posting a bunch more videos throughout the month of December, gift guides, different places that you can go to make sure you get the best deal on products as you're buying things for the holidays. So definitely check it out over at tekthing.com and we're also on Twitter, which is at tekthing. Now, we are down, you know, usually our goal every month is to have one more patron than last month. That ain't gonna happen in December because we've lost more than 100 folks because of the anger at Patreon over the fee. And we understand that, you know, what we're trying to do is say, look, if you still want to support us, if you just don't want to support us anymore, that's a whole different situation that we understand. But if you still want to support our show, check out the fact that we have some fee compensation levels to make up the new fee. Or if you're at the dollar level and you're like, I'm kind of stuck, we have PayPal, we have Memberful, and we're looking at other options for folks and you can find all of them at dailytechnewshow.com. But we still think that, you know, the best way for us to keep in touch with you is patreon.com slash DTNS. And if you're like, I don't like any of those, check out our store. Or even if you like all of those, check out our store. It's still time to snag a holiday gift for that special someone or coworker. We got some hoodies. We got some born ready t-shirts. We got a mug. Go check it out at dailytechnewshow.com slash store. Hoodies and mugs, what's not to like? Maybe we'll even offer bathrooms at some point in the future. Think about it. Our email address is feedback at dailytechnewshow.com. We're live Monday through Friday at 4.30 p.m. Eastern, 2130 UTC, at alphageekradio.com and diamondclub.tv. And our own URL is, can you guess, dailytechnewshow.com. Yes, you can join us again on Monday when Tom will not forget to start the music during Sarah's read. Welcome, join us. We'll see you then. What do you mean by read? I mean, the thing she makes up on top of her head. This show is part of the Frog Pants Network. Get more at frogpants.com. I hope you have enjoyed this program. I don't know who created the wrap up move on and reset at the top. Was it you, Roger? No, it was BioCal. That was BioCal. That's so cool. Yeah, it's a little bit of scripty wizardry. Yeah, I didn't even ask what it was. I just automatically was like, oh, okay, I get it. Cool. I know, what a small but helpful addition to a spreadsheet. I was doing it manually before. You can do that, but it's like 10 times as many clicks. Yeah, this is great. BioCal, you so cool. He's so cool. He's so cool. He's a script and wizard. All right. All right. Show button. There's starting the top with remix. Tom has a gift. First, apple home kit, one more vulnerability. Ability in the eye of the beholder. Act 101 always disclose your hacks. Uber's horse, Pucky. Oh, Pucky. Uber held for ransom by a bug bounty hunter. Just a guy in Florida. Apple is finalizing a deal to acquire Shazam. The app to let you identify songs, movies, and TV shows by audio. This according to TechCrunch recodes says the deal is reportedly worth $400 million. I will say. Considering that Shazam was one of the first apps where I was like, oh my gosh, the iPhone is magic way back in the day that Shazam has been around forever. It still is magical to me. Yeah, I use it all the time. I mean, not every day, but like often I'll be like in the grocery store like, I don't know. I like this song. I have to know. You know, I use it in two. There are two big use cases for Shazam for me. One is I'm watching a TV show and there's music that they're using in the show. And I'm like, oh, what is that song? The other is I'm in a lift and whoever's driving has like their own music mix going on. Yeah. And you know, I could ask them, but sometimes I'm just like, what is that? It's the magic of it. And it's gotten so much better too about filtering out what it considers like a conversation, you know, and knowing the difference. It used to be finicky. Like if you were sitting at a, you know, a busy restaurant and there was music and somebody was talking and it would just get confused. I almost always get a result within two seconds, no matter how like ambiently loud it is otherwise. And basically you either get that result in two seconds or it's just doesn't know the song. And that's pretty rare that it doesn't happen. Right. Right. Yeah. Have you ever tried having a song into Shazam to see if it figures it out? I've tried. I tried to mix results. Soundhound was the app that would do that. Oh, it wasn't great at it. All right. Oh, Biocow is cool. That is true. Hide your hack for a mere 100,000 bucks. Bathroom Friday. What do we got? Remix. Uber has a $100,000 problem and a hack is one. Hide your hack, hack 101. Always disclose your hacks. App a home kit. One more vulnerability. Just a guy in Florida. I would have thought there had been more Florida man. Florida man, something. Isn't that like... I think that one's spent. That one's old. Is it not showbot.tv? Yeah, showbot.tv. Why isn't it loading? Well, it's not going to be for long because Biocow is making a showbot that will work for multiple places. So it'll eventually be, I think, dts.showbot.tv. Correct me if I'm wrong. I think one of my extensions is blocking it from running. So what do you guys think title was? Oh, Biocow says go to irc.showbot.tv. Or dts.showbot.tv. Either one of those works. Ah. Sorry. No, I accidentally clicked. You guys decide on the title. I'm busy. I say... It's not loading for me. Not even dts.showbot.tv. Let me try incognito mode. Incognito.  How do I not have skit downloaded? Title, I need a title. Uber has a $100,000 problem and a hack is one. Or Apple HomeKit, one more vulnerability. Or hack 101.0 is disclosure hacks. I like hack 101.0 is disclosure hacks. Yeah, I like that one too. That's a good one. We have consensus. I'm so messed up right now. I'm writing the names of the people on the show. Sarah Lane, Tom Merritt, Roger Moore, Shannon Morse. Roger Moore. Well, you know, I've been mistaken for... I just don't know why he didn't say anything. He just sat there the whole show. I think I was thinking Shannon Morse already like in my head. That's why I did that. Roger Moore. Do-de-dee-dee. So sad, but do-de-dee-dee. Roger Moore on the show. Who was the oldest actor to play James Bond? Really? Yeah. So hack 101.0 is disclosure hacks. Is that what you guys discuss? Yes. Thank you. That. Yeah, I forgot to make the blog post ahead of time, which always makes it a little bit of a scramble. Are y'all seeing any fires down there? Cereball fire was fairly close to me, but that one's well under control now. The other ones are a little a lot farther north from me. You've got one near you, Roger, but that one seems like it's starting to get under control now too. I see the smoke, but I don't see... Like, I don't actually see the flames, unlike the ones in the summer where I actually saw the hill. Yeah. The Thomas fire up in Ventura is the really bad one. Yeah. That one's threatening Carpenteria right now. Is that a Nexa Santa Clarita? It's near Ojai, in Ventura County. Ojai. Oh. Let's see. Oh. Ojai. Oh, well.  I thought this was easier. Skitch. What are you doing? Well, all I wanted to do with... You know, it's if you want to do something extremely simple that doesn't require Photoshop, like put two images together and then just save that as an image. I thought Skitch would be my best course of action, but I haven't really opened this in a while and it can be a little confusing to me. A lot of times when I open those things, they need updates before I can even use them. Well, I actually didn't even have it downloaded on this Mac, which is weird because it should have... I mean, I've had it for years, but whatever. Open an image. Fleepflurp.com goes to Shobat, apparently. Just because. But that's because BioCAD changed its host's file. So you could also change your host's file to take Fleepflurp.com. Fleepflurp. Fun with your host's file. On the next, Daily Tech News. Can we do that on the screensavers and... Oh, yeah, we did host files. I remember I messed with some host files on my machine at Tech TV because of that segment. I think because I was editing the article or something. I remember messing with the spies on the set and that was not good. Oh, good, the jackhammer's back. Oh, good. I don't know if you guys can hear it. It's my old pal, Jack. Can't hear it. Hey, Jack. It's a Jacques Hammer. Yes, he's French. You know the family guy one? And no, Monsieur, this is a Jacques Hammer. Oh, yeah, I don't know that. It does the... I shouldn't do it. Because Patrick Beja told me he was offensive. No, he is French. Oh, is that an offensive thing? We asked him once and he said, yeah, I kind of because he said, Rich, there's nothing remotely close to that sound or enunciation that they do. It's like you see an American every time you see them going, y'all got my guns. Yeehaw, Yankee Yankee. I like that you know what's funny is I didn't really think it was funny until you get the Yankee Yankee portion. Who was that? Then I laughed because that's funny. Yankee Yankee. It was the Yankee Yankee that really took it. Yeah, that's really what did it. I think it's true. W's got us once like, can you do that again? No. I don't think I could. I almost swallowed my gum. My kitties are all passed out right now. Mine too. Tired babies. Where are they tired from? I don't know. Well, I do know. Starbucks was up at 4 a.m. in my bedroom going and I was just like really? Four o'clock in the morning. Yeah, just like that. It's like why? No reason like you get out of bed and then she's just like goes in circles and starts purring and I'm like, okay. Well, that was possession. I'm bored.   Oh my gosh, I know like no helping with rent. You know, demanding food. Like, you know, I'm the only one who cooks ever. It's just, it's a really unfair situation with my cats. There's nothing cuter than how happy they are after they've like bugged me for half an hour and I finally get out of bed in the morning and they're like, party. Yep. Happy Friday. Let's eat. You know, like a very fun hour for everybody. Yeah. Our dogs are the same way. Ray will now just sit there. I like I'll open my eyes in the morning and Ray will just be sitting there staring like, how long? Have you been like that? I feel the heat of the cat eyes. Like even when my eyes are closed, it's like, I know when they're just there and the thing is, is that they're so good at like, if they see your eyes flutter, it's over. You can't just be like, nope. I'm going back to sleep. They know better. And then once I actually get up, you know, party USA, they're all. It's really cute though. It's actually motivating. It is. Makes me smile. Well, with a dog, at least a good sized dog, you can strap them to a harness and have them tow your sled. What? I'm just trying to think of a job that a cat could do. I guess rodent, rodent patrol would be one. You have too many songbirds in your area. You let the cats loose. Yeah. That's what my grandma used to prohibit the cats in her neighborhood from doing.  How would she prohibit the cat? Would she like, I mean, it didn't really work. I'm just saying she would try. Shake her finger at them vigorously. She would tell the neighbor boy not to shoot the songbirds with his BB rifle either. That worked better. Nothing better than a jackhammer though. That's all I got to say. Hey, if you are not a patron, get ready for a DTSLabs tomorrow. If you're a patron, you already have it. Everything you need to know about loot boxes with Patrick Beja and Scott Johnson. DTSLabs games coming in your feed tomorrow. Tomorrow, tomorrow, tomorrow. Then go to the store and buy a hoodie. Maybe. You know, there's somebody in your life that would want a DTSLabs hoodie, right? I don't have that money. Yes. What's those license holders start coming down in? I'm telling you hoodies. Who doesn't like a hoodie? Right. That's what I'm saying. In fact, if I could complain about living in a, you know, nice, warm, temperate climate, which I can't because I complain about anything. It's that because half the year, it's like too hot for hoodies, but a hoodie is so nice.  You kind of get the hood like a little pillow. In fact, I'd wear a hoodie if I didn't look like I was in pajamas, which I would. DTS grills. DTS grills. Yeah. Right. You know, kind of like a something understated. You know, we'll talk to Dave. What's possible to get DTS grills in the store? This is an interesting fact just because we were talking about things in here. Did you know that if you get a tattoo right here, right where? Hold on like at the like inside your lip. Oh gosh. Okay. Which is the thing that people do that it is semi-permanent. Oh, really? It's like because of the mucous membrane or whatever. Like you have to just get rid of the whole lip otherwise. The whole lip, it just goes away. And I know this because a friend of mine who's a little nut so she had a pizza tattoo.  Why did you do that? And she was like, Oh, don't worry. It'll be gone in like a year. It was. What? That's so weird. Oh, wait. You said it's never permanent. Semi-permanent. It's meaning it goes away. Oh, I thought you meant it never goes away. That's why it was usually a tattoo would never go away. But this is a tattoo that can. So you can do something like a tattoo that says pizza. I totally misunderstood that. Yeah. Yeah.  No, it's just a party trick where you're like, Look at this. I've got some pizza on my face. What do you want? What do you want to eat? Pizza. Right. And everyone said that's my party trick. I talked to you pretty funny. Can people just go back to juggling or yo-yo tricks? What do you mean go back to? There's no reason you have to choose. Get your pizza tattoo and do juggling. Well, I'm going to go get some work done. I'm going to go get some pizza and juggle it. Yeah. I need to eat lunch. I should probably do that. Pizza juggling. All right. Thanks, everybody. We'll see you Monday every weekend. Bye-bye everybody. Bye-bye.


All right. Well, welcome back to our second session, everybody. I'm very happy to introduce our next speaker, Professor Gennady Lebesna from the University of Minnesota. He has been a long time contributor to community of algebra in many, many deep and fascinating ways. And he is going to talk about our plus as a big cone Macaulay algebra and characteristic key. So, please. You have the floor. Thank you. I would like to thank the organizers for the invitation to speak. Well, let me start. So, I am going to talk about the fact that in characteristic P. R plus is going to Macaulay. Let me fix the notation. So, let R be a commutative Ethereum. Now K is the fraction field R plus the absolute closure is the integral closure. And that is the algebraic closure. Right now, Hofster and Hewneke celebrated the result in 1992. So, the result says that if R, excellent, Pan refuses to work. Just a minute. Let's see if I can fix it. I apologize if R is excellent. No, still doesn't. You can stop sharing and share it once again. Just a minute. Well, if this goes on. Doesn't work. I don't know what to do. This is very unfortunate. Let's see. Oh, now it started again. So, if R is excellent. Now, here it refuses to work on this page. It works. Here it works. But here it does. I have no idea what is going on. Let me try to do it on a different page. So, here is excellent. And the characteristic of the fraction field is P. Then R plus is Cohen McCoy. So, what does it mean that it's Cohen McCoy? That is, every system of parameters is a regular system. Since many of the listeners are graduate students, I understand. I need to explain everything. So, let me recall what an SOP is and what a regular sequence is. So, if D is the dimension of R, a sequence of D elements x1 through xD in R is a system of parameters. If and only if the dimension of R, the ideal they generate is equal to zero. That's number one. And number two, I just can't believe this. When I get to this part of the page, it doesn't write. It's very, very strange. It never happened before. So, this is very new to me. I don't know what to do. All right. I think I need to erase. I need to finish this on this page. So, I need to erase this thing and continue. I apologize. It's very strange. So, x1, xD is a regular sequence. And our module, xI, multiplication, xI. If multiplication by xI on M, x1 through xI minus 1, M is injective. The statement of the result of Hofstra and Unicare is that I need to erase, unfortunately, because I have a problem with the iPad, which is very surprising to me. So, the statement is that if R is a local commutative Ethereum excellent ring, then R plus has the property that it is Coint Macaulay. A Coint Macaulay R module and Coint Macaulay represents that every system of parameters is a regular sequence on R plus, on the module. So, that's the statement. Now, why is this resultant? Because if the existence of a Coint Macaulay module over a ring is that the ring has many nice properties. And the statement of the Hofstra-Unicare result is that every domain, every local domain as long as it is excellent has such a Coint Macaulay module and moreover it is fairly simple and easy to understand. It's R plus, the integral closure of the ring inside the algebraic closure of the fraction key. Unfortunately, the bottom part of every page seems to be unusable. That's very strange. So, the proof, the original proof was quite long and complicated. However, in the year 2007, Heunek and Lubesnik published a fairly short proof of a very similar result. Not exactly the same, but a very similar result. So, they published a considerably shorter proof. The entire paper is only six pages long. The entire paper. And if you consider that the introduction and the list of references take up about two pages, then the proof itself only takes four pages. So, I would recommend to the young people who are listening to read the paper because it's a very short paper and with really a minimum of effort you can get a lot of understanding of how local cohomology works for proving a major result because it is a major result, in fact, that our class is quite difficult. So, since I have a problem with using the bottom of the page, I don't know if I can fit this into a single page, but we'll see. So, let me state the main result of the Heunek and Lubesnik paper. If our prime is an r-algebra and r-double prime is an r-prime algebra, then the map, the inclusion or the map, r-prime to r-double-1, prime induces a map on local cohomology. So, the map is from h i sub m of r-prime to h i sub m of r-double-prime. Now, what is m where m is the maximum ideal? So, here I am assuming that this is it, but not allow me to write. Very strange. I don't know what to say. So, the inclusion or the map of r-algebras or more generally, a map of r-modules induces a map on local cohomology with support in any ideal, of course, but in particular with support in the maximum ideal of r. If you assume that r is a local ring. All right. So, now I need to go to a new page because of this very peculiar problem. So, theorem. You'll make it a Desnick 2007. Assume that the characteristic of the fraction field is p and r, r is a surjective image, a Gorenstein local ring a. Let r-prime be an arse of algebra, k-bar is, I hope you remember, it's the algebraic closure of the fraction field k of r.  So, r-prime is an arse of algebra of k-bar, finite as an r-module over r. Let smaller than the dimension of r be an integer. Then there is. So, there is an r-prime sub-algebra, k-bar, that is, r sits inside r-prime and this sits inside k-bar, so that the inclusion of r-prime into r-prime induces the map. So, that's the map h i sub m of r-prime to h i sub m of r-prime is 0. All right? The paper... Oh, there is something in the chat. All right, so this must be about the paper. All right. So, the statement is that if you have a finite extension of r inside the algebraic closure of the fraction field, then there is a bigger finite extension of that r-prime with the property that all intermediate local cohomology with support on the maximal ideal vanish as you go to r-prime. That's under the assumption that r is a local ring, a local domain. The characteristic of the fraction field is p and r is a surjective image of a Goronstein local ring. So, you can see that here the assumption on the ring r is slightly different than in the result of Hoxter-Hunigate. Hoxter-Hunigate assumed that, in their result, assumed that the characteristic was p, r was local, and it was a local commutative netherian, of course, and it was excellent. So, here the assumption that r is excellent is replaced by the assumption that r is a surjective image of a Goronstein local ring. And the two assumptions are not equivalent. So, strictly speaking, these are two different theorems because they are proven under two different assumptions. However, let's see, it still allows me to write Tham, oh, no, this is it. I can't write it anymore. All right, so, what? Just a minute. So, in 2016, Vietnamese mathematician Tham Hoan Kui proved the same thing under the assumption is r double prime finally generated. So, that's the question. Well, let's see. I thought as an r-algebra. All right. And there is an r-prime sub-algebra. Yeah, I didn't say it here. I should have said that r double prime is not only finally generated as an r sub-algebra. It is a finite extension of r. So, both r-prime and r-prime are finite extensions of r. All right? So, that's the statement. Unfortunately, it still does not allow me to write below the line. This is very, very strange. I don't know what to tell you why this is happening. Okay. So, Tham Hoan Kui proved that the same is true. The same holds under the assumption that r is a surjective image of a coin makoli. And it was known. It was known that every excellent ring, every excellent commutative material and so on, is a surjective image, a local. So, every excellent local... I'm omitting everything else. Local commutative, netherian, and so on. Ring is a surjective image of a local coin makoli ring. Local coin makoli commutative, netherian, and so on. So, therefore, the result of Tham Hoan Kui proves or unites the two theorems, the Hofstra-Hunike theorem and the Heunike-Lebesnik theorem in one result. The proof follows the lines of the paper by Heunike-Lebesnik and it provides, therefore, a much simpler proof of the original result of Hofstra-Hunike. All right, so now let's go back to the statement of the Heunike-Lebesnik result. And what does it mean about r plus? All right, so it says here that certain local homology vanishes in the image. The paper by what? There is a chat. The paper by Kui is the following. Okay, so is r double prime independent of just a minute. Is r double prime independent of the i? I think here is that there is an r prime so that is equal to zero. This map is equal to zero for every i smaller than the dimension of r. For every i smaller than the dimension of r. But even if I didn't say it, yeah, but if you have, finally, many r double primes, then you can take the compositor, that is the smallest suborgibor that contains all of them. And it will be the suborgibor in which local homology in every dimension, in every degree smaller than the dimension vanishes. All right, so you can certainly make r double prime independent of i as long as i is smaller than the dimension. And there will be many r double primes. So now the question is, what does this have to do with r plus? r plus is not mentioned in the theorem. So what does the theorem have to do with r plus? So here is the corollary of the theorem h i sub m of r plus is equal to zero for all i smaller than the dimension of r. All right, so why is this? Here is a proof. Well, r plus is the limit over all r primes that are finite extensions of r inside the algebraic closure k bar of k. Right, and therefore local homology commutes with direct limits, so h i sub m of r plus is the direct limit of h i sub m of r prime.  Now the theorem says that for every such r prime, there is another r prime that is a finite extension of r and sits inside k bar so that the image of the local homology module in that of this r prime and that other r double prime is zero. So this, therefore, every local homology module of every r prime in this limit is equal to zero. So that's a consequence of the theorem. Therefore, h i sub m of r plus is equal to zero for all i smaller than the dimension of r. And this looks like something that everybody knows is equivalent to the property that a module is going and it is indeed equivalent under the assumption that the module is finitely generated as an r module. Here, there is no such assumption. r plus is not finitely generated. So yet, it is still true that if the local homology of a module vanishes in degrees strictly smaller than the dimension of r, I should say, if the local homology modules of r plus vanish in degrees strictly smaller than the dimension of r, then r plus is quite Macaulay. So let me recall what Macaulay means. Macaulay is defined in terms of in terms of sequences. All right. So where did I state the no, I think I stated it here. I think I didn't state the theorem of Hoxter-Hunikey. So the theorem of Hoxter-Hunikey says that if r is an excellent local commutative Nazarian ring, then the r plus is quite Macaulay in the sense that every in the sense that every in the sense that every system of parameters is a regular system, it is a regular sequence. All right. Sorry. So how are you going to show that the vanishing of local homology below the dimension of the ring implies that every system of parameters is a regular sequence. So here is another corollary. This is something I can prove. H every system of no, no, it still works in this part of the screen. Every system of parameters of r is a regular sequence on r plus. Here is a proof. So let corollary basically says that r plus is a coin Macaulay r-algebra. So let x1 and so on through x d be a system of parameters. So d is the dimension of we are going to we will prove by induction on j that x1 through xj is a regular sequence. So if j is equal to 1 done since r is a chain and therefore multiplication by x1 on r plus is injective. So we assume j is bigger than 1 and x1 through xj-1 is a regular sequence. So we set it equal to x1 through xt for all t smaller than j9 what did I do for all t here is where it refuses to work. So I need to continue here. So for t it is x1 through xt for t smaller than or equal to j-1. So there is a short exact sequence. The short exact sequence 0 to r plus modulo i t-1 r plus to r plus modulo i t-1 r plus to r plus modulo i t r plus to 0 here is multiplication by xt so this induces or produces a long exact sequence of local co-homology with supporting m.  So this shows that, like I said, the only associated primes of r plus modulo x1 through x j minus 1 r plus are the minimal primes of the ideal x1 through x j minus 1 and since since x j is not in any of the minimal primes it is regular on r plus doesn't allow me to write it's a regular on r plus modulo x1 through x j minus 1 r plus alright so this shows that x1 through x d is a regular sequence on r plus so this means that the main result of the Hewne-Kirou-Beslin paper indeed shows that r plus is going on calling now what about the proof of the main result the proof of the main result uses the following the proof of the proof of the main result of Hewne-Kirou-Beslin uses the following the main result of the Hewne-Kirou-Beslin paper is what I stated in the beginning that for every finite extension are prime of r there is a bigger extension of r still finite as an r module so that the maps on the local cohomology modules are all 0 assuming that the degrees of those local cohomology modules are smaller than the dimension so uses the following two facts number one the Frobenius section on local cohomology so r prime to r prime to r prime and the map says every element to the pth power induces an action f over star on local cohomology modules this is called the Frobenius section on local cohomology and this exists only in characteristic p in characteristic 0 it's unavailable and secondly local dology it says the following fm is a finitely generated r module and minus i is isomorphic to h i sub m so a now keep in mind that a is the the Goranstein ring that surjects m i no longer can write and m little n is the dimension of a this was mentioned in the statement of the result of uniculobesnic in the beginning that the hypothesis on the ring r is that it's a surjective image of a Goranstein local ring a now the star so the star over here is the Matlis dual model so my time is almost up I cannot say anything about the proof but like I said the proof itself is fairly short the paper is only six pages long and the proof itself is only four pages and with everything that I have said in the talk the proof of the remaining things are only three pages long I would strongly urge especially younger people who are interested in seeing how local go homologies use and the proofs of major results to read the paper because for a minimum effort it's a fairly short proof only three pages and you'll get a substantial result an understanding of a substantial result in commuter to Bolsheva and the last two minutes I'd like to mention an amazing an absolutely amazing very recent development by Bargav he is an Indian mathematician who lives in America brilliant Indian mathematician I should say and he has a question in the chat can any our prime be coin Macaulay can any other prime be coin Macaulay well in principle I don't see why not but I doubt because if there was if there was a coin Macaulay finitely generated extension finite extension of R then it would make the coin Macaulayness of R plus unnecessary so even if it exists it would be a rare case in most cases for most rings R there wouldn't be a finite extension that is coin Macaulay so Bargav proved the following flat R the domain local and commutative and etherean excellent and so on of of mixed characteristic residual characteristic the periodic completion R plus is coin is an absolutely amazing result that completes decades of work in this area the proof is not at all simple it uses major machinery developed by Barton Scholtze prismatic cohomology it's called and the idea of the proof as he writes in the paper is suggested by our paper with a unicorn so if you plan on ever reading his paper I would suggest that you start with reading very short paper of ours which I should repeat once again is only six pages long and that's all thank you everybody for listening thank you Gennady are there any questions or comments if not let's all thank Professor for an excellent talk an amazing result


You have to go all the way back to last year, December 1st. Last time BSU women's hockey team suffered a loss since then. They've rattled off six straight, including last night in a thrilling overtime win. Their last non-conference game of the season this afternoon. They go for the sweep over Mercyhurst. No score first period, but Kiki Radke changes that. Sneaks one past the keeper for her third of the year.  Look at the pass from Celine Frappier to Summer Ray Dobson for the goal. That'll tie it at one. Then the third BSU thinks they have the go-ahead goal that's ratty with her second of the night. But this gets reviewed, and the rest signals no goal for goalie interference, so stays one-one. Then the Lakers take advantage just moments later. Brooke Hartwick top corner on the break. That ends up the game winner. Tough one for the beavers. The winning streak is snapped. Two-one is your final score.
