Hey everybody, I am Nathan from Nintendo Prime. Welcome back to our first scheduled video. Monday through Friday, we plan to have videos out just like this one at 11 a.m. central time. Now, there's a bit of a caveat on potentially tomorrow's timing due to a certain event happening in the gaming industry that we may or may not be covering live. Obviously if we're covering that live that will cause a delay in this video but we'll have to wait and see. Also, there's another event we might be doing shortly after this video is published but we'll again talk about that a bit later in this video cause we have eight big stories to talk to you about today and here is a little preview of them. Hopefully you're seeing something over on that list that's this a way that actually interests you. That being said, we do have a new channel for our Nintendo Prime podcast that I am encouraging you guys to go subscribe to. In fact, if you do subscribe and hit the bell icon on that new YouTube channel for our podcast, you will get a bonus entry in our Prime giving giveaway for the Nintendo Switch OLED bundle. So we have some cool bundle items happening with this and I am happy to tease another item that's going to go along with the Switch OLED bundle and that is a brand new satisfied grip intended for Switch OLED. So we're going to get the new Switch OLED specific version of the satisfied grip sent out along with the Switch OLED. I mentioned this is going to be a bundle so there's going to be more items in there as well. Obviously the winner of this bundle gets to choose a charity of their choice for $100. Now we do have a live stream you need to attend in order for us to announce that winner but if you are subscribed to our channel that's one entry and if you're subscribed to our second channel for the Nintendo Prime podcast that is a bonus entry. So get those entries in while you can, link's in the description to subscribe to those channels and in the pinned comment. And I appreciate all of you guys' support both on this channel and our brand new Nintendo Prime podcast channel. That being said, let's get into today's Nintendo news. So first up we have a small little note from the creator of Deku Deals. Deku Deals is a website we talked about during a video last week that puts up a lot of video game deals not just for Nintendo but other platforms as well. And Nintendo Life interviewed the creator of this website that's been around for a little while and there was one particular part of this that I thought was worth mentioning because in general, the guy who runs a website is just someone like you or me running a website. I've ran websites before, not necessarily always noteworthy to interview but there's something brought up that I don't think gets enough attention. So here was what the creator of Deku Deals was asked. How do you think Nintendo could better improve its eShop interface and usability? And he says, from a usability perspective, the eShop is just way too slow. The pages take much longer to load than they should and even the animations run poorly. It also has a little ridiculous that putting the console to sleep while the eShop is open will usually cause it to close with an error message next time you turn the console on. I've actually seen this happen myself. I kind of started to dismiss it as a minor annoyance but it does occur. And I think that this is just worth bringing up because obviously most of the time when we talk about the Nintendo Switch eShop, we're talking about how can it improve in terms of its content discoverability and presentation. We don't often talk about that. It's actually getting a bit long in the tooth, getting close to five years in, in terms of just how well it runs and the speed of it. It seemed a lot more snappy in 2017 but that might've just been my memory doing me dirty because, well, guess what? It could've been just a slow back then and it's just more noticeable today as everyone else is much snappier. So this is a situation where there isn't really much I think Nintendo's going to do about it this generation. Nintendo has a tendency to launch these things that seem to work and then don't really maintain them. So I don't know. This is one of those I just want Nintendo to do better but there's no real sign on when or if Nintendo is going to be doing better. So we're just kind of left to wonder, right? Next up, we've been following the ongoing Grand Theft Auto Trilogy sort of debacle since it launched. It's had a number of issues on multiple platforms including Nintendo Switch of course and was removed from PC for sale and they finally did a public response to all the criticism. And since we've been covering all the criticism and all the issues, I think it's only fair that we allow Rockstar to speak for themselves. They are the ones that control and own the IP. And they put out on Twitter, Grand Theft Auto, The Trilogy, The Definitive Edition is again available through Rockstar Games launcher for play and purchase. So this was the PC version that they removed due to issues. We sincerely apologize for the inconvenience and are working to improve and update overall performance as we move forward. Now they could be talking specifically just about the PC version since the first half of that Tweet does talk about bringing the PC version back but it's on their general Rockstar support Twitter. And yeah, it's the whole game across the board needs performance improvements, needs a lot of updates and maybe those updates will come, maybe they won't. Rockstar did outsource the GTA Trilogy as someone corrected me in a prior video. So we'll have to just kind of sort of wait and see on this approach. But all we can do is really hope for the best. The Grand Theft Auto is one of the biggest IPs in the world and deserves better. But there's a lot of IPs that deserve better but get treatment like this. So yeah, let's just hope for the best. And like in six months, the game is in a much better state. Now I did note by the way that even in the current state the game is in, there's millions of you that are going to still have a blast with these games because they're still really good games. So take that for what you will. All right, next up we have a bit of news on Shin Megami Tensei 5 and this news may be upsetting to some if it comes true but I'm also not going to overreact because I don't think it's that big of a deal. But it's a big enough deal to talk about because people worry about this. Shin Megami Tensei 5 might actually only be a temporary Nintendo Switch exclusive. It just came out last week. It is a Switch exclusive. Nintendo's helped market the game. But yeah, it might only be a temporary Switch exclusive because data miners have discovered in a file that talks about the versions and the target platforms that the game was targeting Switch PlayStation 4 and PC. Now it's possible that these are actually just left over little code bits and fragments from early development before Nintendo swooped in and helped make it a Switch exclusive. It's also possible that this is sort of like Octopath Traveler that was Switch exclusive but then later went to all platforms. So this is just something to keep in the back of our minds that Shin Megami Tensei 5 may still be Switch exclusive but it also might just be a timed exclusive. This is something we're not gonna know and hasn't been publicly talked about at this time. It's unlike Monster Hunter Rise where it was known before it came out on Switch that there would be a PC version a year later. So we knew that essentially there was going to be a delay but a one year exclusivity thing. In this case, that has not actually been announced but it wouldn't be surprising. I think the one upsetting aspect about this for Switch owners and this isn't, again, more people getting to play this amazing game is always better, right? PlayStation 4 and PC, bring it to Xbox as well, screw it. Everyone should get to enjoy the wonderfulness that is Shin Megami Tensei 5. But I will say this, if Shin Megami Tensei 5 was a multi-platform, where's our persona game? I think it's only fair that if we're sitting there showing up big for Shin Megami Tensei 5 that you're willing to treat us like all the other consumers out there and actually give us persona. So I'm all for this going multi-platform but if you're going to do that, Persona 5 and others better be coming to Switch. I'm just saying, okay, don't leave us in the cold while you bring something we have that's really great to other people. By the way, still bring it to other people because I truly believe and more people getting to play great games is better. Like if it'd be advantageous for Nintendo, I wouldn't even care if they put Breath of the Wild on PlayStation, Xbox and PC because more people to get to play than Mario. In fact, if Nintendo would start supporting PC the way Xbox and PlayStation do, even though PlayStation gives the games there later, at least they still do it, I think that would be a beautiful partnership. It'd actually help curb maybe some of the people that like to emulate by offering people a PC version of their older Nintendo Switch. I'm not saying like come out Nintendo and give us a PC version of, I don't know, Pokemon Brilliant Diamond, Shining Pearl tomorrow. But I am saying, hey, no Breath of the Wild, Splatoon 2, would it really be so bad if you had PC versions officially for that four years later? I don't know. Maybe you guys are gonna crucify me in the comments for that one. So this next story is one of our non-Nintendo stories but I like to make sure that we stay up to date as gamers on a lot of the major events happening in the video game industry. And today there's actually a massive Xbox event because Microsoft and the Xbox team are celebrating the 20 year anniversary of Xbox which also happens to also be the 20 year anniversary of Halo which launched on the OG Xbox back in the day with the Duke controller. Yes, I was there folks. There's something nostalgic about 20 years ago Xbox. So just wanna remind you guys that it isn't 10 a.m. Pacific a day or an hour after this video goes live. I am still undecided on if I'm going to be live streaming this event or not. I am leaning towards live streaming it depending on how long it is but we'll see. Normally this involves at least a half hour pre-show but again, we'll have to wait and see. I need to give this video a room to breathe as well. Maybe in fact we might launch this video if it's ready early just to make sure we're making time for that event. But we'll see. Supposedly it's gonna have a shadow drop of Halo Infinite multiplayer. There's been a ton of rumors around the multiplayer shadow dropping today and being announced at the event. It's also possible that some have said hey it's actually still gonna come in November but there's been a little bit of internal delays. We'll probably see a look at the Halo Infinite campaign potentially today and who knows what else, the whole event's not just going to be Halo.  There's gotta be more and Xbox could really use a nice little boost for 2022 even if a lot of what they talk about is not gonna be today. I mean, can we see perfect art? Can we see next games from Bethesda? There is a lot of stuff that we could see moving forward so we'll just have to keep our eyes peeled today but yeah, there's a high chance I'm probably gonna live stream react to it just because I try to do that for the bigger industry events and 20 years of Xbox seems like a pretty big industry event even if it's not Nintendo. All right, next up, we covered this a little bit on live stream last night but I wanted to talk about the fact that Doug Bowser is finally putting on his Reggie Fesame cap and responding to some controversies at Nintendo including Joy-Con Drift and N64 emulation on Switch. Now on the ladder there when it comes to the N64 emulation issue on Switch, he says we're constantly looking for ways to make our online features and those games better and continuing to add value through more services and more games as we go forward. We take the feedback very seriously and we're continuing to look at ways to improve the overall performance. For us, it's about quality, great content and great value and that last line is probably got a few Nintendo fans chuckling because quality, you could question, great content I think is a little bit unquestionable, great value can also be questioned as well just in general especially when we're talking about anything with Nintendo Switch online. So I'm not going to poke too much fun at it. He's just putting on his best Reggie Fesame face and just doing what he's supposed to do and that's spin negative stories in the positive ones. Reggie Fesame was a maestro at doing that and Doug Bowser is just following suit. I don't blame him. He's literally one of his primary jobs is to be a good PR person for Nintendo of Japan. So I mean this is kind of the response. I do like that they are listening to feedback but whether anything comes of it, we'll find out in due time. Now he does talk about the Joy-Con drift issue and he kind of reaffirms something that Nintendo's already stated but he's much more bold about that affirmation because last time Nintendo talked about Joy-Con drift they said that they have addressed it but also every controller's gonna drift. So they're like, oh they addressed it by not addressing it, they addressed it by admitting that yeah controllers are just gonna drift in general. It doesn't matter what we do, which you know somebody felt like it was a cop out but ignored the context of the whole response. So he just gets straight to the point. As we've gone through the first five and a half years of Nintendo Switch, which who wants to tell him? Do you want to tell him? Should I tell him? Hasn't been five and a half years Doug Bowser. Hey I'm just, you're the president and CEO of Nintendo of America. I'm just saying you might want to know how long your platform's been on the market. Now you personally might have had access to a Switch for five and a half years but the five-year anniversary's March 3rd of 2022. I'm just saying Doug Bowser, you just might want to remember how long it's been available publicly, not privately. I'm sure it's been five and a half years for you. Not us. Anyways, just a small little clip.  Anyways, we've observed gameplay and we've observed as people have returned units how they've worn and we've been making continuous improvements overall to the Joy-Con including the analog stick. This latest version, the Nintendo Switch OLED has the same updated analog stick that's now available in the original Switch and Nintendo Switch Lite. So in other words, this is exactly what Nintendo told us before but instead of like dancing around the topic by saying all controllers are gonna drift eventually which is a factually true statement and it just lets it some trepidation. They're supposedly used higher quality parts instead of you know, addressed something basically the core of the drift issue. Again, I can't test it. You probably can't test it. Nobody's really tested it. Time is just gonna tell if the newer Joy-Cons, newer Switch Lights, newer OG Switches start to have drift in a year because we're gonna need to give it some time. Switch OLED's still a little too new to know if it's suffering any major drift issues. Next up, speaking of industry-wide events. Now we talked about the Xbox event. Now we gotta talk about the Game Award. So we will be live streaming reacting to the Game Awards on December 9th and tomorrow's a big day because tomorrow is when all the award nominees are announced. They're doing this through a live stream at 9 a.m. Pacific Time which again is 11 a.m. Central Time and this is where I talked about if I end up doing a video tomorrow maybe it gets delayed because we'll be live streaming reacting to the TGA's. We'll have to wait and see on that. Just like today's video might have came out a bit earlier than my usual or my planned 11 a.m. slot just because yeah, we got another industry event to cover. So industry events obviously take a little bit of priority because they're live events and we wanna cover them as they happen. We don't wanna have to make you guys wait for that news. All right, so yeah, I'm pretty excited about it. Pretty excited about the nominees. Probably gonna be a big topic on the Nintendo Prime podcast this week again. Go subscribe to the podcast channel. So yeah, let's stay tuned for that. All right, our second to last story deals with Breath of the Wild 2 and it's a bit of a cop-out story but I still smile because Nintendo has been throwing out infographs and graphics advertising their games for next year like crazy and on every single graphic is the sequel to the legend of Zelda Breath of the Wild. There's not even like a proper title font or anything because they haven't announced the title of the game but Nintendo not only has it listed in their investors meetings that's still coming in 2022 they're actively advertising to consumers still after announcing that 2022 date earlier this year at E3 that they are going to really sit next year. It is a 2022 game. Now again, that doesn't mean there won't be delays. We don't have any exact release information release month, release quarters, timing of the year, holidays, summer, spring. We don't know anything other than it's supposedly coming next year but it is nice to see Nintendo confidently reminding people, hey, Breath of the Wild 2, the sequel to Legend of Zelda Breath of the Wild, it's coming in 2022. I find that to just be a little bit reassuring on the worry that we might have that it gets delayed out of 2022 but it still could get delayed. Zelda games seem to always get delayed. I just hope that maybe this is the exception. After all, it's had almost as much development time as the original Breath of the Wild and the engines already made, the visual style already exists. So the only real excuse for it to get delayed to 2023 would be COVID, right? COVID messing up the development cycle. I guess we'll find out, won't we? Next up is our last story and we're returning the Shin Megami Tensei 5 again because yeah, you guys probably guessed it at this point. Like pretty much any Nintendo Switch game that comes out, it's fully playable on PC emulators. At this time, it actually took a day. It wasn't fully playable, day one in a good state, you could load it up but now a day after it came out, obviously we're now on the Monday after it came out, it is fully playable on at least two PC emulators right now and we have some news updates on this directly from the emulators themselves. So it says this one comes from the Rio Jinx on Discord, mentioned that Shin Megami Tensei 5 aka Persona without the heart is playable.  It's also possible to run past 30 FPS with B-Sync disabled, the tab key toggles it as it has a dynamic frame rate and won't speed up. However, known issues in this emulator is that shaders don't cache, so the game relies on your driver's cache, expects shader compilation, stuttering, resolution scaling is very inconsistent and doesn't seem to work with most of the time and there are a few reports of crashing. It also is running on the popular Switch emulator Yuzu, who is claiming they can get the game running all the way to AK. So it says, yeah, Shin Megami Tensei 5 is playable, day one in Yuzu, survived the post-apocalyptic nightmare at up to 8K resolution and don't forget to disable the frame limiter for a buttery smooth dynamic FPS experience. Don't worry about stutter, our shader cache will keep hiccups to a minimum, even if you close and reopen the game. And then yeah, obviously throughout this, you have actually seen it, a video of it running on Yuzu this whole time. So the footage of Shin Megami Tensei 5 you saw was actually one being ran on an emulator. So I don't know what to think about a story like this. It's both good news and bad news. Like it's good news for people like gamers that are trying to get options to enjoy their Switch games besides Switch. It's also bad news for people like the people who made the game or Nintendo who are trying to prevent piracy. Now, granted, not everyone enjoying this game through emulation is pirating the game, but we can't ignore that it's obviously part of the equation. So this is again one of those stories, just like with Metroid Dread and Pokemon Brilliant Diamond Shining Pearl, since that leaked super early. It's gonna be a story of Breath of the Wild too. It's gonna be a story with any Switch game moving forward. The Switch is just an easy system at this point in 2021 to emulate. Its hardware is obviously 2015 tech that 2021, 2022 technology can absolutely shred in terms of performance. So it's not really surprising to see it emulated and the Switch is using more modern architecture. So it's not using some special power PC or some other weird architecture that doesn't functionally run well on current hardware. It's using, you know, Maxwell level of stuff, which, yeah, that's PC architecture. So that's another reason why it's so much easier to emulate. So, hey, it is what it is. That's right, I brought that phrase into this video. I think it's the first time I've said it. Maybe. You guys can let me know. Maybe get the counter up and down in the comments if it's been more. Anyways, thank you folks so much for tuning in. I am Nathan Robodes from Nintendo Prime and yeah, I know I didn't have any special image up in here, just let my rotating desktop background go, yeah.  I had a lot going on because we have that Xbox 20th anniversary event coming up, so, yeah.


Have you ever wondered what makes you unique?  And where is all of this information found? Well the answer to these questions all boil down to DNA, and today we will explore what makes up this important substance. In eukaryotes, DNA is found in the nucleus, where it is stored and packaged into thread-like structures known as chromosomes, which we can see in the presented diagram. These are found in almost every one of your cells, and these chromosomes contain genes and are inherited from your parents, and this is why you look similar to both of them. Now let's discuss the structure of DNA, specifically we are going to cover the basic unit of it, known as nucleotides, and these are compounds consisting of three molecules, which are a deoxyribose sugar, a phosphate group, and a nitrogenous base. And we can see this structure here to the right. There are four types of nucleotides, each of which contain different nitrogenous bases, and these bases include guanine, cytosine, thymine, and adenine, or G-C-T-A, respectively. And on the right side we can see what these bases look like. Whilst there are four different nitrogenous bases, the sugar and phosphate group are all the same in every nucleotide. Now let's talk about the bonding between the nitrogenous base and the sugar. These two molecules are paired by an N-glycosidic bond. When the two compounds are bonded, they form a nucleoside. Now note, it is not a nucleotide, which contain phosphates. So you may be wondering how do all of these nucleotides bind together? The sugars from one nucleotide bond covalently with the phosphate of the following nucleotide in the chain. This is called a phosphodiester bond, and these bonds are the high strength ones that form the backbone of DNA. Looking at the diagram shown here, there is a nucleotide and these bond together with adjacent nucleotides, via the spots indicated in the red circles. Then note that this high covalent bond strength makes the backbone difficult to break apart. So this is what this looks like. As we can see, the covalent bonds form the backbone, which is made up of alternating sugar and phosphate molecules. The bonds within this backbone, including those inside the nucleotide, are called phosphodiester bonds. Now we are going to talk about how the nitrogenous bases from one strand undergo hydrogen bonding with the bases from another strand, which forms the overall double-stranded DNA. Now this bonding is complementary, meaning that guanine binds with cytosine, and thymine binds with adenine. The reason why this occurs is because thymine and adenine can bond together with two hydrogen bonds, whereas cytosine and guanine bond together with three. Now when these two strands bond together via complementary bonding, they form the double-stranded structure of DNA, which creates a double helical shape as seen here. Another point to cover is the fact that DNA is bound to proteins. These proteins are called histones, and they help in the process of condensing DNA so that it can fit inside the nucleus. So essentially, DNA is tightly coiled, and it wraps around histone proteins so that it can be nicely packaged as chromatins within the nucleus. Now during cell division, chromatins duplicate and condense even further to become chromosomes, otherwise they just exist as chromatin network. The image seen here is a karyotype, which is the set of 46 chromosomes found within most of your cells in the body. As you can see, there are 23 pairs of these chromosomes, and this is because you get 23 from the maternal side and 23 from the paternal side. Each pair of chromosomes is known as a homologous pair.  Here, this is a karyotype of a genetic male, as we have an X and a Y chromosome. In summary, today we learnt that DNA has two strands that are made of a backbone, which consists of alternating sugar and phosphate molecules, and nucleotide bases, which undergo complementary bonding. And remember that this occurs between adenine and thymine, or cytosine and guanine. We also learnt that the two strands form a double helix. Lastly, we explored that in eukaryotes, DNA is condensed, coiled, and stored in the cells nucleus as chromatin or chromosomes.


Hey friends and welcome back to my channel. I am Yoshida and this is Norris Cove. So I have been slacking. I must admit I've slacked in my faith planning. This was my last spread and I didn't even make it so obviously that was June 9th. So I can't believe I thought because I was sick and oh no, I take that back. So this was the 10th. So I attempted and this particular time I was like I need to just get something done and this is what I was supposed to do. So I love the simplicity of this and I think I'm going to do that again. Matter of fact, these pages need to be taped because y'all have bled through so I just that so I love the simplicity of this. So what I'm gonna do, I haven't even thought about it and I'm not in my filming order. I have a filming order that I like to film in but I realize that I have not faith plans and I'm like I am slacking. So what I like about faith planning or creating a spread for my faith planning is that I can just create whatever I want. I can do whatever I want. So I try not to, I'm in my washi tape here. I try not to overdo it. I like it simple but at the same time I want it pretty if that makes any sense. I think I'm gonna use this one. I haven't used that. I want to pair that with something else though. Um, you know what? I use some of my petals. I did. I use some of my petals and I like those. So I may use some petals. I'm gonna use that and I just don't know. I'm just gonna wing it and go for it and then I'm gonna just make some lines. I'm trying to use, you'll be sent a lot of washi because I'm trying to use washi that I have not used and some of this washi, like I said, I've had since I first started planning and I just tried to buy up all the washi. So we're gonna just keep it simple, but I really enjoyed faith planning, but I had got back sick. So I just didn't do anything in my faith planner. So so now we got some petals going on here and I think that is enough of those. Ooh, vibrant, pretty. And I'm just gonna write. And I see we got some turquoise. So to bring that turquoise back in, let me see what I got here. And I'm gonna use this turquoise mouth liner. Yeah, let me tell you something. How about I just realized this comes off? I just realized that because it came off by accident and that's how I figured it out. So here I'm just gonna outline and my turquoise mouth liner, the date, and then up under the date, I'm going to put the scripture. So now I have that and per usual, I need a quote, gender 52. I'm going to see if they have something that matches what I'm looking for. Oh, I love this here. It says, he makes me as sure footed as a deer enabling me to stand on mountain heights. I'm gonna, so that's in the corner. Let me see. What else we have? Oh, I love this. I am fearfully and wonderfully made songs 139 14. Bam. That's what we need. That's all we need. It says, be still and know that I am God. I'm going to sit that right here. Oh, sure. I got some bees. So I'm gonna take that up because one day I might want to use some bees. Okay. So that is it, you guys. I hope you enjoyed this faith plan with me. If I didn't speed it up, basically I just use washi tape, which I can't remember where I got it from. And I love this one. I think I've used this one before. And washi tape and some pedals that I got from Walmart. And that's it. And my sticker book from Agenda 52 just for some nice quotes. I'm done. I'm finished. I love it. And I hope you do too. If you are new to my channel, please hit the subscribe button, come back for more content. Also hit the notification bell so that you are notified whenever I upload content. And I would love to welcome you to the Cove. Thank you all so much for watching. And I will see you in my next video. Bye.


All the readings, the homework assignments, and the quizzes will be available through the MyOpenMath site. To get there, first, go to www.myopenmath.com. Now if you haven't already done so, you may need to register as a new student. So let's do that first. Filling out the form is pretty straightforward. Your instructor will give you a course ID and an enrollment key to sign up for the correct course. Then, once you've signed up, or when you return to the site, go ahead and log in. And you'll get to a page that may look something like this. Over here in this courses you're taking are the list of courses that you've registered for. So if you already have an account, or if you've been using MyOpenMath, there will be some other courses that you have here. Or in later semesters, there may be new courses that you have. Or you may want to just search for a course, and you can do that as well under the Enroll in New Class. But let's take a look at this Math 1006 course. And this takes you to the main course page. And if you click on the triangles, it'll open up the section. Now as you open up more and more sections, your screen can get a little bit cluttered up. So here's a useful thing to do. Go over to this Isolate tab, and that will isolate the current section.  And if you need to navigate back to the main page, you can navigate along the bar up top. So each section is broken down into a couple of different parts. Here we have the online text. So clicking on that will take us to the text for the course. The text opens up in a new tab, so if you want to get back to the site, go ahead and click back on the original tab. Each section has a set of homework problems. And we'll talk about those in more detail later. At the end of every chapter, there's going to be a chapter quiz. Wait, don't click on the quiz! Before you take the quiz, which will affect your grade, you may want to look at the practice quiz first to know what to expect. This is a set of problems from the chapter. These are review problems for the quiz. Once you're done, you can go back to the navigation tab, which will take you back to the main page. And if you think you're ready, you can take the actual quiz by clicking on it. But be warned, these are timed, which means that once you start, you have a certain amount of time to finish. And there are no extensions on this time once you've begun.


I'm going to talk about how to fill in the truth table for the AND, the conjunction of a sentence. First, you fill in the truth values for P, which is always true, true, false, false. And for Q, or the second statement, which is always true, false, true, false. This guarantees you have all of the combinations you need. For AND to be true, both statements have to be true. So here in the first column I have P is true and Q is true. So P AND Q is true. In every other case where I have P true here but Q is false, that means because they're not both true, the P AND Q statement has to be false. In the third row, P is false, Q is true, so they have to vote. Because they're not both true, P AND Q, the conjunction is false. In the last example, they're both false, so P AND Q is false.


Hello from Embedded World in Nuremberg, where we're looking at the field of motor control and ST's long and proud history in that field. Jean-Marc Mathieu has joined me. Let's start by talking about the new motor control ecosystem that utilizes the STM32. You know, in motor control, the trend is moving from basic universal induction motors towards the PMSM motors with field-oriented control. And there are four main reasons for that. With PMSM motors with field-oriented control, you can reduce the noise of the motor, you improve the efficiency, you improve the reliability of the motor and then you reduce the overall form factor of the motors. Therefore, ST decided to develop a complete motor control ecosystem. When we talk about the ecosystem, we mean software algorithm, hardware boards, libraries, trainings, documentation, etc. And we are continuously improving this ecosystem. For instance, in 2014, we introduced a new version of the ecosystem, the version 4.0 in which we provide more accessibility to the motor control library. We give more accessibility to this library and we provide also new features like the high-frequency injection, the HFI, which is very interesting for applications which need full torque at low-speed or zero-speed applications like white goods in home appliances. Doesn't ST already offer a state-of-the-art motor control system? Yes, you can have the best software algorithm. The first step in motor control still remains to start the motor. And to start the motor, you need to know the basic parameters of the motors, the resistance, the impedance and the back EMF. And some people may have some issue to determine to identify those parameters because, for instance, the specification of the motor is missing or you do not have the right equipment to measure those parameters. And you may have a lack of know-how or lack of experience to measure those parameters. And besides this, it takes time to measure them and it can lead to errors. So how can developers solve those problems there? Very simple. We develop new features like the motor profiler. In fact, this motor profiler will automatically detect the parameter of the motors, then set up the software library and start the motors. So in other words, you plug and spin new motors within less than one minute and without any additional equipment. In the same spirit, we develop another feature which is called the one-touch tuning. And the purpose is to set up the speed controller according to the load plugged on the motors by changing only one parameter. So in other words, you tune the motors with only one parameter. Now these new features are on the software side of things. What about hardware? Good question about the hardware. In fact, with the hardware, we follow exactly the same spirit as we did on the software. Still to ease the accessibility of the motor control for everyone. So we develop a new offer, the motor control nuclear pack. So this nuclear pack is made of three different materials. A small low-voltage BLDC motor plus a driver board based on the L6230 and a nuclear board based on the STM32-S3 nuclear which operates six steps and field oriented control solution. And with this material, with this bundle, you will be able to evaluate easily the software solution for the motor control. And it would be very interesting to do fast prototyping and for education as well. Thank you very much for your time. You're welcome. Thank you.

I just came to some house and a family in Coimbatore. It's part of the Indian tradition that if somebody comes home, the first thing is always, the first form of welcome means a glass of water, always. So this lady brought a glass of water upon a tray. I looked at her, she looked like Kali to me. You heard of Kali, all of you? The non-Indian people, you heard of Kali? Kali is a terrible form of a goddess, tongue hanging out and blood oozing everywhere and all that. So I said, you're looking like Kali today, I don't want to drink this water. The moment you say that I don't want to drink water, this is another thing, you must know if you go to a South Indian home, if they bring water, you don't say no, you sip it, you understand? If you say no, they'll get terribly offended that you're refusing to drink water in their house. So now I know another kind of drama will begin. Then I said, okay, you sip the water first. She sipped it and said, no, not at all. That means she thinks I'm using her as a food taster and she says it's good water. What she means by that is I have not poisoned it.  Just give it to me a moment. She gave the water to me, I just held it in my hands for one minute and gave it back to her and I said, drink it. She drank it and burst into tears and started crying loudly. It is sweet, it is sweet, she is crying. I said, that's all it is.  You can either turn this sweet or make it poisonous, it's up to you. That's all it is. So the water today, we know about this in so many ways in India, Tirth. In every temple there's a Tirth because water is capable of memory and intelligence. Today much research has gone into this. Every molecule of water, water molecules which gather and make it to water cells, they have a phenomenal capability to remember things. Everything that happens around the water, it remembers. Everything that it comes in contact with, it remembers. It is alive. It is alive and intelligent. Water behaves just about the same way as human nervous system behaves. If you, if you take this water and just look at it with a certain emotion, immediately the molecular structure will change. If you look at it with a different kind of emotion, it will change differently. It is no more your grandmother talk. Even today in traditional southern Indian homes, if you go and see, water is kept like a deity all the time. With vibhuti, with sacred ash mirrored on it and properly worshipped every day it is worshipped before you drink because we've always been conscious that water has memory and if it has memory of the right things, it will do the right things within you. If it has memory of the wrong things, it will do wrong things within you.


Every year I want to be in a Christmas commercial. You think maybe I'll still have time to get cast in one? No. And this is the third year that I'm making my own Christmas commercial because I was in cast in one. So my friend Vittoria is here and she's helping me make this one extra special this year because she has a fancy camera and also I'm not by myself. So there's Vittoria. Hello. I am videographer for the day. I try to post these annual Etsy Christmas commercials way before Christmas so that if you're interested in purchasing something from the shop you can and gift it or whatever but it did not happen this year. And here we are on Christmas Eve and I'm going to finally share this year's Christmas commercial. This shop isn't really a shop. I just had skates. I pretty much already destroyed my vision board from 2022 because I'm making the one for next year. But I had skating on my vision board. One of my goals this year was to be in something that was Christmas-y and something that had to do with the skates. And two birds with one stone because this commercial is going to have both. Sometimes as an actor you get hired for something and then you don't get a job for like a month, weeks, whatever so you have time in between so something I love to do is come up with an idea, contact local filmmakers or friends that are filmmakers and create something. In the position of the filmmaker, the creative of all of this, I got heavily inspired by the Etsy commercials that are running. I always look at their commercials just to get like a vibe of it. It's like if I was in an Etsy commercial, what would it be? So my plan this year was to make the commercial 15 seconds like a short little spot and make it super emotional, heartwarming, like make somebody cry. I was very specific in everything I wanted but I still realized that my creative side in doing this, I'm still not great at it. I think I'm getting much better than like 2017, 18 me of like making random little things like this. Just some of the shots didn't work out because of my decision of how I wanted anything. So this was a really great learning opportunity for me, even though I'm just doing this for fun and I want to be in a Christmas commercial. Definitely recommend it if you are also an actor or a filmmaker. Do some little spots and experiment with your creativity and what you're doing, what camera you're using. Like I've been using my phone. I personally think it's fine where I know a lot of filmmakers are like, I need the specific camera, the specific lens, specific lighting. So it does make a difference but as somebody that's learning, I think just use your phone, just be creative, just have fun. Like that's how you're going to learn by doing it a bunch of times, not by trying to perfect something and like perfect how you're approaching it or how you're going to do it and then doing it. I really, really believe in doing it again and again and again until you get better at it and you're able to finally do it. And here is this year's Christmas commercial. Create your own traditions and share them with the ones you love. Etsy has it. Here's this same video but from 2020, if you want to see like my creative process of when I came up with the idea and hopefully I'll keep doing this maybe next year instead of me being like, okay, time to film the Etsy Christmas commercial, it'll be me filming a behind the scenes of filming an actual Etsy commercial. How fun would that be? I'm putting that on my goals board for next year. Where is Etsy based out of?


Hello, everyone. So today I'm going to talk about browser fingerprinting, and in particular about an experiment that we did at EFF to measure how fingerprintable web browsers were called panopticlic. So let's start about, before we get to browsers, let's talk about identifying information. Now when we ask what kind of information identifies a person, we have some standard sort of answers. Like, oh, if I know their name and address, I probably know who they are. But there are some more surprising examples of identifying information. There's a paper by LaTanya Sweeney from the 90s that showed someone zip code and their date of birth and their gender, then you have about an 80% probability of being able to identify them uniquely. Now that's a bit surprising and counterintuitive, so let's see how it happens. If you start with 7 billion people on the face of the planet Earth, you rapidly narrow yourself down, if you know a zip code, to a group of about 20,000 or maybe 50,000 people, maybe in some cases 100,000, but not very many. And then you can divide that number by 365 because you know their birth date. You can divide by a more complicated number that's about 70 because you know how old a person is. And then you can divide in half again because you know whether they're male or female. And it turns out that if the zip code you started with had fewer than about 50,000 people in it, you now probably have a unique person at the end of this program. So there's a mathematical measure you can use to say how identifying a set of facts about a person is or how much information is required to identify someone. If you need more bits to identify them, then each bit doubles the number of possibilities. And if you're learning more facts about them, then each bit you learn halves the number of possibilities. So you can think of these as trading off against one another. So for instance, on the face of the planet Earth, with 7 billion of us people, you need about 33 bits to learn the identity of one of us. And if you learn someone's birth date, what day of the year they were born on, you learn about 8.51 bits. So if we talk about a random variable you might measure like someone's birth date, you can talk about the amount of information you learn when you learn a particular value of that random variable. So if we're talking about birth date and you learn that my birth date is the first of March, then you've learned 8.51 bits about my identity. If, however, you learn that my birth date is the 29th of February on a leap year, then you get a bit more information because the likelihood of that being true is only a quarter of what it would be for any other birthday. So you get more information, 10.51 bits, typically. So we call that first measurement the surprising or self-information of a fact you've learned. So a surprise that I was born on the 29th of February, 10.51 bits. And then we can talk about the entropy of this type of measurement, which is the expectation value of the surprise. So if you have a probability distribution, you measure the expectation across all of that. There's some formulas you can use to look at this. We have a paper on our website that has all the mathematics in a bit more detail if you're interested in it. A point to note is that you can't add surprises together. If you learn someone's birth date and then you learn what city they were born in, those two things are probably independent variables, not entirely but close to. So you could add the number of bits together. But if you already know someone's birth date and then someone tells you their star sign, you're actually not going to learn any more information. So if you want to know how two of these measurements add together, you need to do some fancy stuff with conditional probabilities. So what use is all of this theory? Well we can apply it to tracking web browsers. Now what do I mean by tracking web browsers? Two things.  And also if on a given day you go to two different websites and you maybe look up one fact on one and then another fact on another and then the question is could these two sites get together and combine the facts and get a deeper picture about you, either of those would be tracking. Now there are at least three ways that are widely discussed to track web browsers. You can use cookies, which are these little bits of information your computer will store and send back and sites can put serial numbers and tracking numbers in them. But of course we all know about, we're at DEF CON, everyone here knows about cookies, you all have browser settings to delete them or limit them. So we can survive cookie tracking. And IP addresses, everyone knows about IP addresses but IP addresses can be hidden by a proxy server or you can move from your house to your friend's house to the cafe to work and each time your IP address changes. Lastly there are these quite nasty things called super cookies, the most infamous example being flash cookies. They are essentially exactly like cookies except when you tell your browser not to set cookies, flash still has some other settings page that you haven't changed somewhere and so flash is still storing its own kinds of cookies. And you can think of these things as hoops that you have to jump through in order to get privacy on the web. If you want to not be tracked you have to avoid tracking by cookies, avoid tracking by IP addresses, avoid tracking by super cookies and then if you do that it's time to talk about whether you can be tracked by a fingerprint. So fingerprints are like Latanya Sway's example of tracking someone with some inane facts like their zip code and their date of birth. It turns out that the characteristics that web browsers have like the version of the browser, what operating system it's on, et cetera, combine together in the same way as those other facts and perhaps they make your browser unique. Now there are different degrees of uniqueness that you might get out of the version information on a browser. You might have complete global uniqueness. So you're sitting there in the third row, your browser is completely unique in the whole wide world and we know it. So when we see, we can track your browser. But perhaps that's not true. Even so, browser fingerprints may be a problem because they mean that your IP address combined with your fingerprint is uniquely identifying. So if you guys all have your laptops opening or surfing during my talk, please don't do that. But if you do, then perhaps there are 2,000 people behind a proxy server here at DEFCON or surfing at once and so that gives you some degree of anonymity except if you all have fingerprints that are not unique in the world but unique at DEFCON at least, then that would be a tracking mechanism. Another possibility is that fingerprints don't track you all the time, just whenever you go and delete your cookies, your fingerprint is unique enough to link your old cookie to your new one to give you a new copy of your old cookie back again, a zombie cookie if you like. And the last thing that makes fingerprints really nasty is that unlike cookies, they're automatically the same when different sites collect them. So if a website over here sees your fingerprint and a website over there sees your fingerprint, they see the same thing. If they both tracked you with cookies, they'd get different cookies and they'd have to have some sneaky process to link them together whereas fingerprints are automatically the same. So we heard a lot of rumors at EFF about fingerprints. We heard that some web tracking and analytics companies had started using them. We'd heard rumors that web-based DRM systems were using fingerprints to track people. We'd heard that they were being used as a backup authentication mechanism for financial systems which is maybe less of a problem than the first two. And we got really curious about how effective this method was. We were also worried about a more mundane question which is every single time you go to a website, almost all websites are configured to log your browser's user agent string. And we were wondering how much of a problem that was. So we decided to get some numbers to find out.   And if you click on that, you get a page that looks like this that says, oh, your browser appears to be unique, at least up to 20 bits, possibly more of identifying information coming from your fingerprint. And then there's this little table here showing what all the component measurements were and how identifying each of those were on their own. So you can see there's a user agent string, there are accept headers, plugin details, et cetera. Really telling stuff in there, this font. I'll talk about where these came from more in a second. So these are the eight measurements we had. These top three were just, they're just things that you always send to a web server when you ask for a page. The next four come from JavaScript. So there's a little bit of JavaScript that runs in the page and if your browser supports JavaScript and it doesn't have it disabled, the JavaScript will collect this information and send it back to us with an HTTP post command. And lastly, if you have Flash or Java installed, we'll go into Flash or Java or both and ask those plugins for your list of system fonts. So yeah, so we have these different measurements. It'll turn out that the two most problematic ones, they're all kind of problematic. The two most problematic ones are these plugins here and these fonts at the bottom. So there are a lot of things we didn't collect but which you could use to make these fingerprints even nastier. And in fact, it turns out we've since seen that there are companies in the private sector that will sell you a fingerprinting system that doesn't just do the kind of eight things we did, but actually also does a lot of this other stuff. One particularly nasty thing is you can measure the clock skew of a quartz crystal. That is how much faster or slower than another clock your computer is and that's very hard to hide and it's unique to your hardware rather than just your software. You can measure the characteristics of the operating system to TCP IP implementation. You can measure the order in which the headers show up. There's lots of stuff in the ActiveX, Silverlight and other Adobe libraries that we didn't have time to dig through and find the news but you can do that. There are quirks to the way that each browser has implemented JavaScript that could be identified with the right code. There's a really nasty bug that's just recently started being fixed in browsers where you can measure the history of a browser using CSS detection. And some of these things we didn't collect because we just didn't have time to implement them. Some we didn't collect because we didn't know about them. Once we put the site up, we got a lot of emails saying, hey, you could collect this thing as well. And lastly, some things like this CSS history, we weren't sure would be stable enough to include in a fingerprint without some kind of fuzzy matching code that we didn't have. So all of our results, I guess the point here is that all of our results should be taken as a kind of optimistic story about how much privacy you have. With a really good fingerprint, the fingerprint is more powerful and more revealing. So the way we handled the data off our site, we set a three month persistent cookie and we stored an encrypted IP address with a key that we threw away. And we used those primarily to avoid counting you twice. If you came back, we wanted to know if you were the same person with the same fingerprint or another person with the same fingerprint because those are two very different things. And we had an exception for that, which is if at a particular IP address, we saw cookie A and then cookie B and then cookie A again, we thought that's probably or at least potentially evidence that there are more than two computers behind that IP address that perhaps behind a NAT firewall that have the same fingerprint. And that could be important because it could be a sign that there's a corporate network there and there's some sysadmin who clones all the same code out onto all the machines every day. And so there are genuinely multiple machines with identical fingerprints there. And that gives the people in that office some protection. So we decided not to treat those as repeat visits from the same browser if they were interleaved. One thing to note is a lot of people were confused by the numbers we had on our site. Those use the cookies, but not the other methods of avoiding double counting because we had to compute that stuff on the fly for millions of visitors. The data set I'm presenting in this talk has more fancy control for that stuff. So we got a pretty big data set. We had two million hits, about a million distinct browser instances there. The people that we were measuring are not representative of the entire web user base. They're people who read slash dot or boing boing or come to the EFF site. And so they're more of a data set of privacy, people who know about and care about privacy. However, as I said before, you have to jump through three hoops to not be trackable already on the web. And so we think this is kind of the relevant data set to ask do people who block cookies and know about IP addresses and how to hide them and so forth end up being trackable by their fingerprints instead. And another point is that the data in this talk is all based on the first 470,000 odd instances. So the first half of the data set. Turned out people were really unique. 84% of the browsers that came to our test site were unique completely in the data set. If you split the data set up and say let's just look at the browsers that have either flash or Java installed and that's the relevant set if you're talking about desktop browsers, your uniqueness rates go up to 94% and only 1% have a fingerprint that we saw more than twice. So this is the same thing on a graph. Note that this graph has log axes. If you drew this graph of how common the different fingerprints were without log axes, you end up with a graph where the line runs exactly along this axis all the way and then exactly along this one. So in order to see any structure you have to put it on log scales. But the important thing to note is that 84% of the data is right down here in this section on the tail. It's unique. And then there's another group of people about 20,000 people who have an anonymity set size of two. I mean there were two browsers that had that fingerprint. You know a small group with three, four, five and then right up the other end you have a small number of browser fingerprints that were not very unique. The one right at the top is a Firefox instance that's not running JavaScript. So like a recent version of Firefox with no JavaScript, you have a decent amount of anonymity. There's an interesting statistical question that you might ask which is, okay, sure, you saw 94% or 84% uniqueness in your data set but that was only 500,000 people. Would people be less unique if we could get data for the whole one to two billion people who use the web? And this is an interesting statistical question. I have a theory about how to solve it involving multicolor simulations. You try a hypothesis probability distribution. You run it through a simulation. You see if it produces a graph that looks like that. But we didn't try to do this because in a sense our data set which is just a measurement of privacy conscious users is not meaningfully representative of the one to two billion browsers in existence. So if someone else has a less biased data set, you could do this statistical question. We didn't try. Now any graph that tries to show you everything that's going on in this data set is gonna be really complicated because it's half a million data points. But I'm gonna try with a couple of them. This one shows for each category of browsers. So Firefox, IE, Opera, Chrome, Android, iPhone, Conqueror, BlackBerry, Safari, and then a lump together collection of links and other text mode browsers. For each of those, how good or bad was it from a uniqueness trackability point of view? And so if you look at this graph, anything that's over here is a proportion of uniqueness. These things were completely unique in our data set. The other end we have the least revealing fingerprints. So let's take an example. Firefox is this black line. It follows this curve down here, where it has a little bit of a tail in the non-unique area. That's because some people had JavaScript turned off in Firefox or they were running Tor button and it shows up as Firefox. And then right up here, there's a very large number of unique Firefoxes. All of the desktop browsers aside from Firefox are like that but without this little tail of non-unique people. So generally desktop browsers are bad. The browsers that did well, iPhone, the iPhone does very well. It's not very fingerprintable. It's this purple line and there are quite a lot of iPhones that are not unique. That's perhaps not surprising because there aren't yet plug-ins and font variation on iPhones. Really, all you're talking about is what time zone you're in, what language you're in, maybe which version of the iPhone OS you have, but there's not very much to fingerprint an iPhone with. Android does almost as well, not quite as well because there are more iPhones than Androids, but those phone browsers look pretty good. In practice, of course, they have really bad cookie settings so people who use them probably get tracked by their cookies, but this was a good result for the phones. I'll let you guys ask more questions about these crazy graphs at the end. Now, if we look at the variables that we measured, we had these eight measurements and say which ones were the problematic ones. This table measures to first order, which they were. So user agent is pretty bad. It's 10 bits of information. Every time you log in your web server logs, the user agent, you expect on average that you're narrowing the population down to 1,000th of what it could have been if someone wants to browse anonymously. The things that were worse, plugins, 15.4 bits, fonts about 14 bits. So these things that your browser publishes are very revealing. If you wanna ask, okay, what is the distribution of different values for all of these things look like, you end up with this crazy graph here. It's in our paper as well. I can try to explain it. It says how many people, for each of these measurements separately, there are eight different measurements. For each one, how many people fell into an anonymity set size of K for each of the measurements? So an anonymity set size of one means you are completely unique because of your fingerprints or your font or your plugins. So you see up here, there are a lot of people who are unique, 200,000, 250,000 people who are unique just because of the plugins they had installed in their browser. There were 200,000 who are unique just because of their fonts. 20,000, 25,000 who are unique just because of their user agent, et cetera. As you go down here, these are less identifying values. And then along this line, we have right up to the end, having cookies enabled wasn't a very revealing fact. So if anyone has questions about, oh, what does this data look like? You can come back and study this graph and pour over it for half an hour or ask me questions about it. So another really interesting question you might have is, so sure, you can identify people, but don't these fingerprints change over time? Are they really a stable way to track someone if they could upgrade their browser or install a new font and suddenly the fingerprint would be different? And so we decided to check this. This graph shows the set of people who visited Pan OptiClick exactly twice. So we wanted to throw away people who might have been playing with the site, trying to optimize their uniqueness or tweak things. We just wanted people who came exactly twice with at least an hour or two in between the two visits they did. So they didn't just hit reload, they came back later.  And you can see as more time has passed, the likelihood that the fingerprint was different when they came back goes up. We measured this, by the way, with cookies. So there was a cookie that you could reliably use to see the same person and then you can see if the fingerprint changes. So actually fingerprints don't last very long. The half-life of these things is four or five days. So perhaps that's actually a really good sign. Perhaps fingerprints, while they're instantaneously identifying, aren't a stable way to track people over time. Unfortunately, this turned out not to be true. So the way we did that is we said, okay, your fingerprint has changed. Can we do some kind of fuzzy matching algorithm that we'll see if your fingerprint later after the change was uniquely tie-able to your fingerprint beforehand? And I implemented a really hacky algorithm to do this. It just says if only one of those eight measurements has changed and it hasn't changed very much and that maps to a unique fingerprint from beforehand, then let's guess that it's you. And it only tries to do this if you had something quite revealing like flash or Java installed. So this algorithm guesses about two thirds of the time, but when it does guess, it's 99% accurate. So it has a 99% chance of correctly guessing which fingerprint you changed from and less than 1% chance of getting it wrong. So even though fingerprints change quite fast, even though the half-life of a fingerprint is five days, actually you're still trackable once your fingerprint has changed. So there were really only four examples of categories of browsers that survived this. I mentioned them all quickly in passing. If you block JavaScript, perhaps with no script, the Firefox extension to do that, you're in pretty good shape. If you use TorButton, TorButton zaps the plugin list and the TorButton developers knew about a lot of these attacks and anticipated them in various ways. So TorButton, you don't have to use Tor. You can just use the little TorButton Firefox extension. You're in pretty good shape. If you use an iPhone or an Android and you manage the cookie problem, you're in pretty good shape. And lastly, this small percentage of systems that were behind firewalls appeared to have the same fingerprint. We saw about 3% of IP addresses that had multiple visitors coming from them exhibiting that kind of behavior. So that 3% of systems maybe has some kind of anonymity, although it's a bit hard to distinguish that from a browser's private browsing mode. And it would also be the case that if you implemented the clock skew hardware-based fingerprinting, you could probably tell people apart, even if they have a firewall and a cloned fingerprint. So currently, there aren't very many web browsers that do well. We also saw some other really interesting things. One interesting thing was that sometimes privacy enhancing technologies are the opposite. Something that's designed to hide your identity turns out to be the unique thing that tracks you. If you install a flash blocker, for instance, that has a unique signature that you can tell, okay, this browser has flash installed, but we're not getting an answer back from the flash plugin when we ask it for fonts. So people who've done that were all pretty much unique. People who've forged their user agents. Actually, something I forgot to say about this graph, let's go back here. Let's look at this graph here. Remember how I said this is the iPhone in pink, this pink line? And you go over here and these iPhones aren't very unique. And then there's a little group of iPhones up here on the right that is unique. What's going on there? Why are some iPhones unique? Well, it turns out if you look at this, actually a large portion of those iPhones aren't iPhones. This graph just believes the user agent string, but if you go and look, some of these have flash player installed and other stuff that gives them away is actually not being iPhones. They're desktop browsers masquerading as iPhones. And we scratched our heads when we saw this and thought, why are so many people pretending to be iPhones? And then we realized that actually AT&T had had a promotion for a long time where they gave you free Wi-Fi for your iPhone. And the only way they checked that was the user agent string. So I think they fixed that now. But the lesson here is, okay, that's funny, but also if you wanna fake your user agent string, you have to fake more than your user agent string. You have to fake all the other stuff that distinguishes an iPhone from a desktop machine. And if you don't, then you're in danger of creating yourself a unique fingerprint. Similarly, there was a very distinctive bunch of Firefox machines that supported Internet Explorer's ActiveX user data cookies. Okay, those are probably not Firefox. The exceptions to this problematic rule about privacy enhancing stuff, defeating your privacy, the noteworthy exceptions were NoScript and Tor button, which both are fingerprintable, but the amount you gain from having them turned on outweighs the amount you lose from them. Another lesson here is that there's a trade-off, well, sorry, actually, wrong slide. Another lesson here is that if you're designing an API that's gonna run inside a browser, you should never ever offer some call that returns a gigantic list of system information about the machine that you're running on. So this was true both of the plugin list where you just ask navigator.plugins, hey, give me the plugins on the system and you get back a list of all of them and the version numbers of all of them, because that's gonna make a lot of people unique. Similarly, don't return a list of all the fonts. If you really need to show people a particular font, make them ask about the specific font rather than being able to ask about all fonts at once. Perhaps an even better solution to this would be to not have your system fonts displayed in your browser at all. Perhaps if a website wants to render this crazy Frankenstein font I've got here, it should have to give you the TTF file along with the website. The problem here is that even if we block the bits of Java and Flash that give font lists back, there are some nasty websites out there that show that you can detect fonts using CSS, which is almost unblockable. You just render the font inside an invisible box and then measure how white it is, and so if the user has the font installed, the box is with A and if they don't have it installed, it's with B. And there's a little cute website called Flipping Typical that demonstrates this. So this stuff is hard to block. Another lesson is that finger printability trades off against debugability. So if you look at a user agent string, just a hypothetical one here, and this is the typical stuff it has in there. My operating system, I'm running X, particular hardware platform, my language, precise date that my gecko was built on, all this stuff, why is that in there? Like why does every website I go through need to know what date my browser was compiled on? Like what are we doing here? The answer is some people thought that maybe one day we'd wanna debug something. And when we did, wouldn't it be awesome if we'd already logged on the server side all of the stuff we could possibly want for debugging a client-side issue? And okay, fair enough, maybe occasionally there's some glitch somewhere where having this version information is useful. But there's a trade-off between privacy and debugability going on here. And right now, browsers are all configured right up at the extreme debugability and extreme non-privacy end of this spectrum. And at least perhaps when you enter a private browsing mode in your browser, it should be making that trade-off the other way around. The same is true of plugin lists. Right now, if you look in the plugin list and say, well, what version of Flash do you have? It's not Flash or Flash 10, it's Flash version 10.1 off of 53. And so all these little facts, you have 10 plugins and you get this much version information about all of them, it adds up. So the general lesson, right back at the start I said there were four kinds of attacks that you could use fingerprinting for. One is global uniqueness and in a lot of cases it looks like browsers are globally unique. Not all cases, but a lot of them. The second case where you have an IP address plus a fingerprint, there you're almost guaranteed to be able to track someone. And you can definitely undelete cookies that people have deleted and you can definitely link these things across websites. So this is a serious privacy problem. Right now the only things you can do are things that power users are gonna do. You can do no scripts, you can do tour button, but you can't tell your grandmother or whoever else, like just people who aren't really comfortable with complicated user interfaces to use these plugins. So that everyone else is gonna need to wait for the browsers to find a solution to this. Fortunately, they've sort of started. We've been talking to the Mozilla people and they're interested in attempting to fix some of this stuff at least in private browsing mode. Google is maybe a step behind, but also someone interested in trying to tackle this. So perhaps we can come back in a year or two and say we've made a small amount of progress on the problem. Anyway, that's all I have to say. As always, if you like the work we do, either this kind of technical stuff or our legal work support EFF, there's a membership booth over in the vendor area and I'll take questions if anyone has any.


Hey everybody today, we're gonna talk about the set up for the push-up so in any exercise The setup is half the battle if I can get in a good starting position Then it's much more likely and it's easier to cue myself to just stay in that position Rather than trying to find it through the rest of the exercise. I'm not gonna say that the perfect setup You know, maybe it doesn't exist Kind of exists so anything that's really normal for you is good I'm not gonna say that you're not gonna have any other issues if your setup is really good But it is a good way to ensure that you are Maximizing the likelihood of doing it. Well, so With the push-up Set up I always start people on their knees like if if they are a new client for me I start them on their knees because Most people don't understand the finish position and we talked about that in a previous video, right? Spent a lot of time on this. I like to start on the knee. Let me take these off. I like to start on the knees and just make sure someone can Reach like this with a nice round back People are gonna tend to stick their chest out and push like this with their pecs But their pecs won't get them The full finish and the mobility and stability and health neck Benefits that I'm looking for out of a rounded upper back finish position Okay, you might even feel a stretch in your upper upper back area Important when I do this reach I'm not reaching like this. This is not the same thing This is a crunch with a push with my neck and my six-pack ab muscles Instead instead of reaching with this part Look at all my shoulder mobility instead of reaching with this part towards the ceiling I'm trying to reach this part towards the ceiling So kind of like this Okay, not like this But like this Okay, so I want to make sure you can do that on your knees first. That's part of the setup Okay, we simplify the exercise teach you the new stuff and then say okay do it in this more complicated way And then you get better So that's part of it.  So I need to make sure that I set the hips back I'll bias people into their hips being a little higher Because it helps you feel the ab it looks kind of weird and when you do the push-up It's gonna feel kind of weird But it's a nice way to take some tension off of the hip flexor and ensure that your back is in a good position As you progress along you're gonna try to get your hips more in a straight line like this Okay, and then just throw on push-ups outside of that Last thing ankles I'm just looking for somewhere in the middle, right?


What's up, everyone? It's Takedown here. Welcome back to another video. Today, I'm gonna be sharing you the difference between Amazon FBA and selling on eBay. Now, I am a Canadian eBay reseller, but in the past, I have sold on Amazon FBA as well. And right now, I do choose eBay over Amazon, but I am considering going back, depending on the inventory that I do have in stock, and to see if it is worth it. So I decided to make this video. I think I made one in the past, back whenever I was selling on Amazon, but I don't think I did a full breakdown like I am in this video. And of course, there is gonna be a few things that I am gonna miss, but I am focusing on the key aspects between the two. So at first, whenever you're first starting out and selling on Amazon FBA, there is a couple items that you are restricted on selling.  If you click into that, it might tell you that you can get a letter from manufacturer to take the restriction away. That is very, very hard to obtain from my understanding. And over time, the more sales that you generate of things that are unrestricted, you will get a lot of those restrictions lifted over time from my understanding. Now, I never had it go that far. I never stuck with Amazon to get most of those restrictions lifted. I just switched over to eBay shortly after that. I only was on Amazon FBA for maybe five to six months, and then I switched over to eBay and solely sold on eBay. Some of the brands and products that you might be restricted on right off the get go is Marvel, Lego, Barbie, Hot Wheels, basically a lot of these top toy brands and other brands. And that will make it very difficult to find products when you're first starting out as well. For eBay, on the other hand, there's hardly any restrictions. There is a few items that are restricted, but they are common knowledge, and I'm not gonna list everything for eBay because there's a lot less restrictions than there were for Amazon FBA. Now, when it comes to shipping, shipping is why people usually choose Amazon FBA when they're starting out. It's compared to eBay, and I will explain why. So when it comes to shipping for Amazon FBA, you have to ship your products to an Amazon FBA warehouse, and whenever your product does sell on Amazon, they will ship that item to the customer, not you. So you ship your items to Amazon FBA warehouse, they ship their items to the customer. So that's one less thing that you have to worry about, having to make sure your shipments are on time. Amazon FBA, they do take care of that for you guys. Now whenever you ship your items to the Amazon FBA warehouse, you will get a discount here in Canada. It is through UPS, as long as you're doing the shipment through the Amazon app. What would have cost me $60 to ship? Only cost me 30, maybe $35 to ship it with the discount that Amazon gives with UPS. If you're in another country, it might be a different courier, but here in Canada, it is UPS. Now the one downfall with this, with Amazon FBA, is whenever it comes time for you to make a shipments to an Amazon FBA warehouse, they might request you to split up the shipments and send to multiple Amazon FBA warehouses, depending on what they ask you to do whenever you're trying to finalize it. For me, I never had that problem. I was able to ship all of my shipments to one warehouse, but I have seen a lot of people, it might ask them to split up two shipments, ship one box to one warehouse and ship another shipment to another Amazon FBA warehouse. That's one thing to remember as well. Now whenever it comes to eBay, you are responsible for shipping your items directly to the customer. And it has to be within the handling time that you select some of your making the listings. So for me, right now I have 10 days. Usually I ship within two days. Soon I might change that. I might switch mine from 10 days to maybe three or four days, but right now I leave it on 10 days just in case something comes up. I still have time to ship that item. As long as you ship within the handling time, you are okay. But with eBay, you are shipping your item when it sells directly to the customer. Now the final key point that I wanted to talk about is the fees. Amazon FBA has way more fees than eBay does and I am gonna break down most of them, but there is a lot more than I am listing here for Amazon FBA and I just wanted you guys to be aware of that. Now up first, there is two different plans that you can select. There is the individual plan, which is $1.49 per item that you do sell on Amazon and there is the professional plan, which is $29 a month.  You're only paying $30 a month compared to $1.50 per sale that you do make. If you're selling less than 20 items per month, you might as well stick with the individual plan and only pay $1.50 per item that you do sell. On top of that, there is monthly storage fees, fulfillment fees, there is an FBA label service that is optional, but it is 20 cents per item.  So whenever your item is in their warehouse, they scan it, it comes directly to your store and everything is done like that. So it covers up the bar code that is on the product to an Amazon bar code. So if you do not go and do that yourself, you are charged 20 cents per item and that does add up if you are doing larger shipments. There is an FBA prep service fee, which is also charged per item and that is 50 cents to a dollar per item. Now that is for things and items that should be bubble wrapped, a sticker for a suffocation sticker. So if it isn't a clear poly bag, it needs to have a suffocation sticker on it. And poly bags, if required, if you're sending stuff like plush toys, they usually require it to be in a poly bag with the suffocation sticker. So basically if you forget to, or if you just go and make a shipments and you ship it to Amazon FBA, they receive it, but it wasn't shipped and the items aren't how they're supposed to be shipped with if it's a breakable and it needs to be in bubble wrap. Like I just explained a bit, the plush toys and the poly bags with the suffocation sticker, they will charge you 50 cents to a dollar per item for them to do it. So you do want to make sure that you are, if you are creating a shipment to Amazon FBA, it will tell you that this item needs to have bubble wrap, this item needs to have a suffocation sticker and be in a poly bag. If you don't ship it with those items, the way that it tells you to, you will be charged the 50 cents to a dollar per item to have Amazon FBA employees do it. So do keep that in mind. So when it's all said and done, that is a ton of fees that you do have to pay when you are selling on Amazon FBA. Now when it comes to fees for eBay, there is the final value fee, which is between 12 to 14%. For most of my items, video games, comics, things like that, it's near the 14% mark. So I usually calculate my fees at 14% to keep it safe. But there also is a promoted listing fee. This one is optional and you select the ad rate per cents. And if it sells from the promoted listing, then you have to pay that percentage. So let's say you're using the promoted listing ad rates and you select 5%. Whatever your item does sell for, if it does sell via the promoted listing, then you have to pay the 5% on the total value of the item. So the item plus what the shipping is, you have to pay the 5% on that, as well as the 14% for the final value fee, and as well as you will have to obviously ship the item to the customer. So keep that in mind. I do that sometimes, but I don't do more than 5% depending on the item. Sometimes paying the 5% fee means that I'll be able to sell it quicker, but it depends on how much I'm selling the item for. I don't do the promoted listings for every item and I don't always do 5%. Sometimes it's only 2%. It depends on the item, depends on how quick I want to move it, and it depends on how much I'm selling the item for. But this is the difference between Amazon FBA and eBay and the fees alone in my opinion is one of the main reasons why I decided to switch from Amazon FBA and go to eBay back a couple years ago because even though I have to ship directly to the customer, I learned how to do that. I learned how to ship things safely, on time, accurately, and how easy it was. It's so easy to ship on eBay, ship directly to the customer, and that is my go-to right now. Even on Facebook Marketplace and Kijiji if somebody wants something shipped, I can ship Canada-wide all across the United States as well. Usually people just pay me the shipping or I do also offer shipping discounts if I sold that way. If it's on eBay, it's super easy to ship as well. So, when you're starting out seeing the FBA label service whenever they're putting the labels on your items for you, that is very appealing. Whenever you see that there is the shipping advantage so you ship directly to Amazon FBA but when the item sells, they ship it to your customer. That is appealing but at the end of the day, the fees alone on Amazon is way high than it is on eBay. I'd rather take control of my shipments and have to ship my things on my own now rather than leave it up to Amazon and have to pay those outstanding fees unless you are selling a ton a month. The fees versus what you sell does outweigh it so if you're selling a ton a month, you might want to do Amazon FBA but for me, I'm selling average on month. I would much rather do eBay right now. If my sales per month do go up quite a bit, I might have to debate on which one I want to do but Amazon to me is easier starting out but the fees do add up and eBay to me is way easier because you're in control and you are handling everything on your own and if there's a mistake, it's not an Amazon FBA employee, it's solely on you so you do have to take responsibility if you do make a mistake. But hope you guys did like this video sharing the difference between Amazon FBA and eBay and I'll see you guys in the next video. Please take care, peace.


We turn to thank you. Mr. you have the floor I'd like to make a three-point the first point is that I think we all agree that there's a synchronized slowdown And with a potential there might have recession and there are minefield of a trigger to the orders geopolitical factors anything can trigger Some of the economy pushing some of the economy into the recession My question number one is that how can you cope with it? Do we have a right tools to cope with that you're let to talk about monetary game and basically monetary is losing its effectiveness and Good chance that when you know Lower your interest to further and further down with the easy monetary policy actually you create your big That bomb down the road and there's a good possibility that we might end up financing the garbage project For all of those three we're gonna pay the price. My more concern is on the fiscal policy yesterday I guess all your branches mentioned that now because money to policy is tied up in many countries Fiscal might be the only game with the low interest rate, but with all this populism rising in many countries everybody particularly populist politicians are trying to win the election and we do slowly growing or sometimes Decreasing pie. I guess most of the fiscal policy run the risk of ending up Just give away rather than spending in the more productive sectors or facilitate the structure investment and the third thing is that during the 2008 crisis we have a global coordination. We all remember G20 played a very instrumental role I remember that in 2009 and so G20 all the leaders agreed to Stand still and rollback of all protections to measures and that helped a lot to avoid the worst outcome of the 2008 crisis Now we don't have it and we conveniently say, you know so-called New normal about this low interest rate and all the stuff But I don't think we can hide it behind this new normal about lack of international coordination And this is very worrisome particularly for country in Asia because you know Asia has been following our globalization and then we had a crisis two and years ago with all this capital flow and Then we recovered and no ten years ago. We have this global finance crisis But now the question is that if the global coordination or the role of G20 is no longer there if we have a crisis Where can you rely on? Unfortunately, I'm very happy to tell that we haven't made a lot of progress Since the two ten years ago crisis we have created something called Right now they call it RFA regional finance arrangements Europe's ESM Asia has come up with something called C M I M basically it's a multilateralized swap between ASEAN 10 countries and Japan Korea China Even though it's a walk in the progress we had made a lot of progress, but at the same time there are many missing Blocks missing links in terms of the paid in capital because it's all promises But there's no actual paid in capital for example And we don't know how to coordinate once the crisis hits us between IF IMF and This regional finance arrangements and many bilateral swaps So this is also a big concern for many Asian countries and Finally, I just want to mention that no there's something called we agreed on the G20 capital flow measures for Microprudential purpose and in Korea the case in 2008 crisis Even though we had almost no exposure to US house movies market and we had we are sitting on a pretty big amount of Reserve at the time 20 260 billion dollars still because we have a Relatively large short-term debt We are hit by the international investors. There was a pull out of money It was only when we entered with the Federal Reserve Swiping range of the three thirty billion dollars that the hemorrhage stopped But actually when you look at it this short-term debt is another really short-term debt The large chunk of it is fictional debt. It's sort of I don't want to be too technical But it's a forward-sale position of foreign banks in Korea. So after that we implemented two measures basically we charge the bank levy and No, if it's a less than one year borrowing in the inflow stage they have to pay additional 10 base point and another thing is that all those Delivered positions should be linked and limited by the capital base And we did this to measure the what we found out is that the capital inflow does not change in terms of the amount But basically the structure changed. It's much more longer term. It's much more stable and this kind of no capital flow measures of For potential micro prudence of purpose. I guess it should have been more encouraged and explored I am a fit much more positive on that which is a little bit Hesitant toward that but I think you know, this is just something without global coordination particularly we have to Explore more and finally about this, you know, we mentioned about this resetting of capitalism and Because of this perception or actual happening of inequality I agree that we got to do something about it. But what we found out is that We have a now a little left-leaning government which emphasized a lot about justice Fairness equality, but it's all great in saying as a cause, but when you try to implement it You have this nightmare who define justice who define fairness and so all the good intentions Often end up with the pretty bad results as they say the road to hell is paved with good intentions So I'm not saying the efforts is not worthwhile But rather what I'm trying to point out the the risk Particularly on the populism and trying to address this inequality issue You try to push too far and how to find the right equilibrium Is it something we have to all struggle in each countries? Thank you. Thank you very much Oh a lot of potential questions for you in the discussion
