thick necks. Hi, we're live. Now you're laggy. Oh, because we started the. You were fine until you were. It's a little it's like it's like a second. Yeah. I can't tell if I see it or not. Maybe a little bit. But that's much more noticeable now that you're doing that. Yeah. Well, that's that's why it's yeah. No, I can see it a little. Hmm. Well, it's better than it was last week. Mm hmm. Yeah, that was rough. It was like a full second or two behind me. Yeah. Oh, boy.  I guess it is. Why? Why is that? Why is that? I was already on the World Series last week. I'm not sure what you mean. It's true. Oh, and I think to myself, what a wonderful world. I don't see you, Charlie. Trees are mostly brown. Mostly, I would say, well, it depends. Like a redwood is green because like a willow could be mostly white. Well, I guess just from the outside, I guess, you know, in terms of mass, mostly bark, mostly bark. Well, what you see in terms of color is the outside. So it really just be I wouldn't have anything to do with the mass, but the amount of volume, volume it takes. And then the and the because of volume fall. I told me the outside. I'm at the out the like surface area, surface area. Thank you. You mean not the mass, the surface area. Yes, that's right. That's right. Right. Right. Is better than that. All right, so we afford a new laptop. Why do you need a new laptop? I don't know. Oh, are you just having are you just having jealousy because there's new laptops out? Are we going to start now? Yeah, we could start now. I don't have to. I'm OK with looking at Instagram for another couple of minutes. I admire your dedication. Your dedication to the craft is exemplary. I showed up and showing up is half the battle. It is half the battle. You're absolutely right. Yes, it's just the other 50% that kind of completes it. But now we're about to do the other. All right, I'm going to hide. All right. Yep, let's get going. Here we go. Oh, I need control. Oh, I'm glad you said it right then. Almost was too late. OK, three, two, any last words? One, Daily Tech News Show is powered by its audience, not outside organizations. To find out more, head to DailyTechNewsShow.com slash support. This is the Daily Tech News for Monday, November 14th, 2016. I'm Tom Merritt joining me as she does on Monday's Ms. Veronica Belmont alongside. How are you? OK, how are you? I'm great. Great. This is our first week in a couple of weeks where we don't have a guest. But I'm really I'm actually very excited to talk about our topic. There's a there's a few different music pieces of news about online streaming. And we're going to talk about what streaming services we use and why. And you have a plan. Yeah, no, OK. You did know that was the topic, right? Yeah, you could you can hear me, right? Because I did actually have a response to that. What was your response? It was just delayed, maybe you didn't hear me. No, I didn't hear your response. Oh, I said it sounds like a plan. Well, no, that I did hear that. I was took a little bit for that to come. That was my response. All right. Hey, do you like to donate to nonprofits? I do and I donate to many. Well, now you can donate through Apple Pay. Apple Apple's now allowed allowing that they didn't allow that before. Why didn't they allow that before? That's weird, but I'm glad they had the door processing, you know, and the taking 30 percent like Apple didn't want to take 30 percent of charities. So they're I think that's probably what now here are some more top stories. Samsung has agreed to buy Harman International for eight billion dollars. Harman makes connected car and audio systems. You probably remember them as the speaker makers. They have Harman Kardon, right? Yeah, right. Harman Kardon JBL. They have acquired a lot of software over the years, though, as the speaker business started to shrink. So they make embedded systems now for cars. They make telematics. They make some security software for cars like like lock security. They have BMW Volkswagen Toyota amongst their clients. So Samsung is now going to have a top car software maker. They say they're going to keep them as a standalone subsidiary. Although Chief Strategy Officer at Samsung, Young Sohn, said Samsung will not get into the business of manufacturing cars. They just want to make the stuff for the manufacturers. All right. I'll believe it in in 10 years when I see them not having Samsung cars, because I bet they will. You'll believe it when you don't see that on the road. Ten years now. And I remember having recorded this podcast and claiming that, yes, there will probably be Samsung cars. I mean, certainly it makes sense for them to get into the the automotive software side of things that Apple's doing it, Google's doing it. Everybody's doing it. So I think this is a wise decision for them. Saying we're not going to get into the business of manufacturing cars, I think is is managing investor expectations. But if down the road a couple of years, if nothing else, somebody wanted to use the Samsung name on a car, you don't think they'd go for that? Yeah, if they can make money, absolutely. Why wouldn't they? Yeah, Microsoft briefly posted on its MSDN block that Visual Studio is coming to Mac OS. Details will be revealed at the Microsoft Connect Conference in New York later this week. The new Visual Studio will be based on Xamarin for Mac OS. Hopefully I'm saying that right, which Microsoft acquired earlier this year. The MSDN post has since been removed implying it was published accidentally in advance of the conference, which almost never happens. Just kidding. That always happens. It happens so often. Yeah. So Microsoft, sorry, it got up there. People saw it. We know the details and it looks fine. Now, some people are taking issues with the fact that this is really just Xamarin with a Visual Studio name slapped on it. But Microsoft has done some things to it to make it be able to share objects with the Windows version of Visual Studio. So even though it's not exactly the same piece of software, there is some compatibility between it. And, you know, I think we've lost the reaction of Microsoft doing things we never thought they would do because they've done so many of them. But, you know, transport yourself to 2001 when Microsoft is out there railing against the evils of Linux and deriding Apple and minimizing them as a competing platform. And the idea of them bringing Visual Studio to OS 10, or as it is now called Mac OS, seems impossible. Yeah. I mean, they're really getting into the, we just want to be the software makers for any operating system at this point. You know, we just want to make the best software possible for people to use across platforms. Yeah.  So this isn't as big of a step again as it would have been, but it is, it is a big tool for developers. I know a lot of developers complaining about the new MacBook Pros saying they're not as developer friendly, but that doesn't mean there aren't still a ton of people on legacy MacBook Pros and even buying the new MacBook Pro. So you've got developers that are going to use Visual Studio. Attacker's accessed more than 412 million user accounts at Friend Finder Network, including 339 million accounts at AdultFriendFinder.com, which by the way, if you don't realize, it's about being more than just friends. 15 million deleted accounts were in this hall and that is deleted accounts that were not properly purged. So even if you deleted your account on this website, it might be in this access batch. 62 million accounts came from cams.com, 7 million from penthouse.com. The attack occurred near the time a local inclusion flaw on AdultFriendFinder was disclosed. The company was attacked last year, exposing more than 4 million accounts that time.  This latest one does not. However, it does expose passwords. Some of them in plain text, others scrambled with the SHA-1 hash function, which is easily cracking. That's not good. That is not good security.  Yeah. What, Tom?  I was just going to add that a lot of people don't use their actual names and identities on this sort of thing, but they might still reuse passwords. So, yeah, getting email addresses and all that sort of thing is embarrassing in a situation like this. The fact that they've got plain text access to your passwords or easily crackable hash means that you need to make sure, if you were using the site, that you don't use that same password anywhere else. Depends on your priorities, I guess, which aspect of this is the worst. It's the most horrifying thing you've ever done. Yes, yes. I wonder if it was Zedynette or somebody else, but there was one article that interviewed some people who said, well, I never used any of my real information there anyway, which I thought. But if your email address and password are the same, that's kind of a, that point doesn't really matter all that much. As you just iterated. So, yeah, just, you know, use a password manager, change your passwords often. Don't use the same password across multiple services and change them frequently. That's the advice that we just give as a blanket statement of advice in terms of passwords. And it's still the best advice. Turn on that two-factor authentication if you can. I don't, it seems like it's maybe not available at adultfriendfinder.com to factor your account. I mean, it would be weird if they were advanced enough to do two-factor, but still using SHA-1 to hash their passwords, I don't know. And then still stored your passwords in plain text. In plain text, yeah. Why, why? An Indiegogo funding campaign for the Matrix Power Watch claims a fitness tracker can use your body heat to keep it charged. Zedynette Scott Stein reports it creates electrical current from temperature gradients and uses the transformer to amplify the charge. A heat from the low power processor is vented from the sides of the watch to maintain the gradient. The watch will track steps, calories, activity and sleep and has 50 meter water resistance. The Matrix Power Watch plans to ship next summer for $160 and the Indiegogo early bird price is $99. And I just want to say that I am going to make a, I'm going to make a prediction. Yeah, you know, it's a little early for the prediction show, but I'm just going to put this out there. But you're getting warmed up, I like it. It's going to, yeah, yeah, I'm getting warmed up because I'm going to say it's going to burn people. Oh, no, there's my prediction. It just detects something's going to go wrong. It's venting heat somewhere. Something's going to go wrong. I'm just going to put that out there. Probably I have no basis for this at all. No basis. All right. All right. Nothing about the company. It's just, you know, it's going to be 2017 by that point anyway. So maybe things will be better in the world, but you know, it's probably that's what's going to happen. I think it might burn people in its battery life and ability to charge. Scott Stein got his hands on it and was able to look at it and see that it worked. But as he says in his article, and I saw several other people say the same thing, he didn't get to use it for a week. So, you know, I mean, any watch would work for the amount of time that he had to play with it. He said that he did see that the thermal activation would connect and he would see a connection, although it would go on and off sometimes depending on how good of a contact it made with his arm. And the other thing is calling this a watch is legit because it does tell time, but it is really just a fitness tracker. It doesn't do much else. It doesn't connect to a smartphone. It doesn't do notifications. This is just a fitness tracker. In fact, it doesn't even do heart rate because that would do be too power intensive. But it is. I'm already guessing like all the emails people being like, it doesn't store enough power to burn you. And I know this in my rational brain. I don't care. It's going to find a way. It's somehow going to overcome that. Well, that's the other thing is the prototype design is not terribly pretty, according to Scott, but they have they have mockups of what it will look like when it chips that is so whether they can actually keep that heat vented properly and make the pretty design is something interesting. All of this, you know, I mean, this is poking holes in something which we do, but the idea that you could have a workable product that wouldn't need to be charged that can that can just use your your conductive heat, even if it's very simple, pretty great. Yeah. And here I am pooping all over it and it hasn't even launched yet. I should not I should not be so harsh on things before I've had a chance to look at them. It's a good point. We could consider all kinds of other power sources for this thing. I think it was that added not poop as a power source, but but solar and kinetic energy. Like you could if you could combine those into a watch suddenly you can start to create a little bit more power. Maybe it could have a heart rate tracker at that point. Eugene Kaspersky of antivirus maker Kaspersky Labs wrote a blog post complaining that Microsoft's bundling of Windows Defender in Windows 10 is anti competitive Windows 10. If you don't realize it detects and uninstalls unsupported antivirus programs during upgrades. Kaspersky complains that developers don't have enough time, even if they're part of the preview program, to develop compatible software. So and there's no going back and saying, Hey, Kaspersky's antivirus is now up to date. Can you reinstall it instead of Defender? So he's like, we don't have enough time and we get uninstalled because of that. Windows also displays a warning screen that Windows Defender is turned off from times to time. Even if you have an active and upgraded third party antivirus protecting your system. And he says it's unclear to people that turning Windows Defender off will turn off the third party system, so they need to clear that up. They need to give us more time and he's filed complaints in the European Union and Russia. I think that sounds pretty reasonable, frankly. I think that's kind of gnarly. Yeah, I go back and forth on this. On the one hand, I don't think it's monopolistic behavior for an operating system to have its own security like we want that. And it's a little bit like consumer to say you should give us more time to upgrade security. If if you're made and if that means you're you're making consumers wait for updates that could otherwise be installed, right? But at the same time, if you're going to allow third parties, then I think you do need to play nice and having, honestly, I don't know about the disabling antivirus because there isn't enough time. I'm a little unclear on what Kaspersky means because plenty of other software makers are able to update their apps in time for Windows 10 updates. So I'm not sure why he says security in particular has a problem with that. I wonder if it has to do with, you know, if people build, you know, basically figure out the, how am I trying to say here? So if there's a new update to Windows 10, for example, they need some time to figure out what new vulnerabilities are happening in that update and then be able to patch those appropriately. So that to me, that makes sense in comparison to other kinds of software programs out there, but it would it would also make sense for me that that Windows Defender could run in tandem with the is there a reason why they can't leave them running also there? Can they're not they will collect. They will go there and use up system resources and there's a few other reasons. I there should be a way for an antivirus maker to update its software to work with the new updates, right? Even if it hasn't figured out all the vectors and just push updates to that as it goes. The Defender warning that kind of implies that you're not protected, even if you are is bad and Windows should absolutely change that in my opinion. It's bad and they should feel bad. I don't know if they should feel that, but they should change it. Whatever, whatever they feel, they should definitely change that. I'm not sure that it's anti-competitive though. It's it's different than bundling in a browser, right? Like bundling as a security is something we would like software to do. So if I just want to give you a warning if for some reason you start hearing loud alarms and I have to leave, there is a strong smell of something burning in the toaster in the office right now. So hopefully hopefully that will get taken care of. Yeah, no smell ambition. Yeah, TechCrunch reports on MIT's computer science and artificial intelligence lab development of Mover for wireless VR headsets at MOVR. Mover uses millimeter wave technology, same thing being used for 5G experiments to deliver multiple gigabytes per second. Mover does require a line of sight for transmission. So right now the prototype uses programmable mirrors to detect and direct the signal. This is different than the twenty two hundred and twenty dollar Vive add-on that went on sale last week to make the Vive wireless. Oh, I want that. I want that so bad. I know it's too expensive, though. It's a little expensive and you have to be able to translate the Chinese pre-order page. That was another thing that gets in the way of people updating this. But but here we have in one week Vive and now this MIT development moving us towards those wireless VR headsets. So before we've even all decided whether we think VR is real or not, we're making some some good advances, which is great. Also, revelation. I'm looking at this thing the whole time I've been reading this story as MoVR. You know, of course, it's MoVR. Of course, it's MoVR. Like, I don't know why I didn't see that till you said it. Yeah, I think it's it's actually a pretty good name for it, too. That's a great great little acronym. And yeah, this is that's in a lab. So we're not going to see this one as soon. But the nice thing about it, unlike the HTC add-on, it's smaller. They think they can get it down to smartphone size as far as the device you need to have attached to you somewhere. And HTC Vive One could be up to backpack size when they add the battery life to it. Also, it's cross platform. They're like this this could work for anything. It could work for an Oculus. It could work for a PlayStation VR could work for anything. It doesn't really matter. That's awesome. I was talking a lot about VR this weekend and, you know, just the sheer size of all the devices still is problematic for for a wider adoption, I think, unfortunately. And although I did kind of come to the conclusion that I was like, maybe I should get Lasik so I can use VR better. I don't have to have my glasses in the way. I'm like, I'm really thinking of getting like eyeball surgery just so my VR experience is better. Like, I need to find a few more use cases of that first. Suddenly, all of the eye doctors in our audience just decided to order VR headsets for their waiting rooms. It'll be so much more comfortable if you don't have to wear your glasses. Yeah, exactly. Oh, just entertain yourself with our VR headset. By the way, we offer Lasik surgery if it's uncomfortable using that. It's a good neck good neck exercise that we're in those headsets after a while. Good for strengthening those weakening muscles we have from looking down at our phones all the time. I see everything finds a way. Life finds a way when you when you lose your when you lose your next grade from smartphones, someone offensive heavy VR headset for you. It's protopia. That's what it is. Ah, right. Of course. How could I forget? Thanks to all those who participate in our little protopia right here at Daily Tech News Show are subreddit is Daily Tech News Show dot Reddit dot com. Submit stories and vote on them there. Now, one of the bigger stories of the day. We've left out of top stories just because we want to talk about it here. Google released a redesigned Google Play music app for Android iOS and the web on Monday. If users opt in, the app can now recommend music based not only on your tastes, but your location and activities. Now, there's a side story here, which goes along with every new Google thing, which is do you want it to track you and aggregate this information? But if you do, you'll get better recommendations. And so in this this morning, I tried it and it gave me a morning coffee and a workout playlist because it knew I was up at home and it knew it was morning. So it's like, hey, we think you might be doing these sorts of things. And that's the idea. They want to surface different playlists. Like when you're at work, you might get a work playlist. They're a combination of machine learning and human curation. So don't forget that Google owns Songza, which was a company that focused specifically on human curated playlists for various situations. You can also get a personalized playlist available for offline listening if you're a subscriber. Yeah, go ahead. Oh, no, I was just saying, oh. Yeah, well, that's a good point. Rhapsody also announced, well, they didn't really announce it was actually in a real networks filing because Rhapsody isn't publicly owned, but there are 42 percent owned by real networks that they posted a profit of more than $1.6 million in Q3 on record revenue of $54 million. Rhapsody recently rebranded its music app to Napster because it owns the rights to use the name Napster. This story is from today, just even though I said real networks Rhapsody and Napster. Yeah, that was all very that brings me back. Yeah, all of a sudden, we're doing Buzz Out Loud 2006. But no, this story is today. And that combined with Amazon Unlimited Music, which is Amazon's standalone music service. It's not part of Amazon Prime, although you get a discount if you're Amazon Prime. That launched in the US or last month and it's launching in the UK today. Means that streaming music is the stuff that's where everybody is going. And I think this has been apparent for a long time. We've had lots of hand wringing about whether you can make enough money off of it, but everyone's getting into the game. And Veronica, the curious thing about this is Google polishing up its app. Amazon getting into the game. We're seeing all kinds of different regional music apps like QQ Music, KK Box, Angami and Melon. And yet Spotify's got 44 percent of the global market share. At least that's what Midia says as of Q2, like almost half of the market share is Spotify. Let me just guess. What streaming service do you use? Spotify. Yeah. My wife uses Spotify. I asked people in our analysts like what they use. None of them use Spotify, at least none of the ones that were there when I asked the question. So there's another half to this story, right? There there are always this 56 percent of don't. I for one use Google music. And so I think this is a good conversation for us to have because the way we use music apps is changed. And what Spotify delivers you they think is what's keeping their market share up. And so we see these other companies trying to come up with other ways to entice you over. So let's start. Just tell me like why do you use your music apps the way you do? You know, I didn't. I was an RDO user in terms of what streaming service I kind of got in bed with early in the game. Initially, I'd had MP3s for years and years, of course, like everybody else of our age range did. And then when I switched over to streaming, I just really like the simplicity of being able to have it syncing to all my devices wherever I was. And Spotify just, you know, for the bank for its buck is that there's so much there's so much music there. I mean, they really have no problem getting artists to bring their their content to Spotify. But, you know, that's not really a problem across the board anymore these days unless you're doing something like I don't know what the more specific labels are like. But yeah, Taylor's for things like title, you know, James, the album album on there or Taylor Swift is not on Spotify these days, stuff like that. Little little things here and there that can be annoying. But at the end of the day, not a deal breaker for me. But yeah, I just like the price is great. I like having it sink across all my devices. And I really do like the curation that they do. I tend to find that a lot of the playlists that they create are enjoyable for me. And I like that discoverability factor. I mean, I'm not listening to radio the way I used to. So being able to have a method for discovering new music that's outside of my immediate bubble is really nice. And typically, I just use Spotify for having background music when I'm at work during the day. I can't really listen to a lot of vocal tracks when I'm trying to concentrate. So I listen to like atmospheric type stuff. And Spotify has a great selection of that as well. So it kind of and now that it's doing podcasts and video sometimes and things of that nature, it's really kind of expanded its repertoire quite nicely. And I don't really see a reason to try other things. And even in the in the Google ecosystem, you know, we just got a Google got a Google home. And I like it very much. But I, you know, I asked it to play some jazz music when I was cooking dinner last night. I actually picked jazz from Spotify. It didn't default. Oh, really? Yeah. I mean, it might have been Ryan's account, my husband's account. So maybe that was what it was. But I know that if whether I have an Amazon Echo or if I have a Google home, you know, they're I'm able to use Spotify because it's the biggest one and I know it's going to be there. Yeah, I think that is one of the big reasons that Google is polishing up this app right now is Google home. They're hoping will bring a lot of people into Google music. But of course, they're integrated with Spotify as is Amazon Echo, which is another advantage to Spotify. It's it's why Netflix took off in the early days was you could get Netflix on every video player. And now that's a reason why every new home theater system, whether it be, you know, it's if it's Maxbox or PlayStation or any number of home theater devices, they all come with Netflix integrated because now that it's become so popular, that's a selling point. Netflix doesn't have to try to get on these devices anymore. They are being begged to be on these devices, it seems. Yeah, I think Spotify is kind of the Netflix of music in that regard. Now, the number two in global ranking is Apple music at 19 percent. I think that is explainable in large part, not entirely, but in large part by iOS users saying, oh, I like living in this ecosystem. Let me try it out and then sticking with it. We had a couple of people in the Slack say just that like they used to be on Spotify and then when Apple music came out, they switched to it to try it out and they liked it and it just works well with their ecosystem. So there's an ecosystem advantage there for Apple that I don't think is translatable to others. I don't know that Google could pull off the same thing, for instance, with the Pixel. Yeah, I think it's because Apple just also has a reputation built around music now as well, especially with the acquisition of Beats and just being, you know, the the iPod being so ingrained in our collective subconscious is being the music device of a generation. You know, people tend to equate those two things. So that definitely gives them a leg up. Google doesn't really have that as much. Like people kind of know that they have music or that they can store their music that way. But I don't know if it's top of mind in the same way. Now, here's where I do think Google has an advantage that they don't tout as often and I don't think we think of as often, which is YouTube. Looking at streaming hours and this survey is only for the US but it does include non paid services like Pandora and YouTube. Pandora is the number one in the US and Q2 for streaming hours at 30 percent. Number two is YouTube at 27 percent and number three is Spotify at 18 percent. So the other thing that Google is doing here is saying, hey, we know that Spotify is great for discovery. So we're going to try to help with that by making this personalized playlist based on your listening habits and providing these context sensitive playlists that also are informed by your habits as well as curation, right? And what people probably don't understand is even if they've never used Google music, as soon as they sign into this and try it, it will work better because they do listen to YouTube. I think we all underestimate just how much music we watch and listen to on YouTube. Yeah, I mean, I love using YouTube for music. That's that is one of the big reasons I actually go to youtube.com is to watch music videos because they're so hard to just see out in the world these days like YouTube is kind of the place to go like Vivo is like where you go to see music videos now. And that's that's a big win for them. Yeah, and I don't think I don't think Google music is going to succeed unless they make a bigger deal out of that. And that there is a little brand confusion there with Google and YouTube. One of the things I started using Google music because it was at the time the only way that you could combine your catalog of owned music with the streaming music seamlessly in the playlist and it works great for that. Amazon does that now too and a few other services have added that. But I still think Google is the easiest way to do that. I was thrilled when they launched YouTube red because suddenly just by being a Google music subscriber suddenly I got no advertisements on YouTube and I got access to their originals and I got offline playback. Again, I don't think they're doing enough to let people know like you get all of these sorts of things. Right. So I think Spotify is going to continue to be the one that's top of mind to dominate. Yeah. Yeah. But yeah, I I don't use iTunes match because they don't match everything.  Remember when that I never did it for that reason, I'm like, I'm not going to lose all my remaining MP3s because you guys just decide to delete them for some reason. I don't know. Seems like a bad thing. And I did use it would be me. I'm the one who went to tuberculosis, the rare the rare deals fair enough. Fair enough. You've got the mark. But that's not really why I did it. I did it because I stopped using it because with iTunes, it wouldn't match anything less than 30 seconds. And I'm weird. I got little less than 30 second music things like from They Might Be Giants. I've got old commercials that I like to have just, you know, thrown in my playlist from the 40s and 50s for atmosphere. It wouldn't match any of that stuff and it wouldn't even match some of my my nerdy or weirder songs. Whereas Google Music just said, hey, look, that's your song. It's up here. We don't care how long it is.  Now it's there. You can put it in your playlist. And so that's why I ended up using Google Music. But I don't think a lot of people care about that. I don't think that's a very common concern. I mean, maybe maybe they do. That would be an interesting survey to kind of to kind of run of how many people actually do that. I'm sure those those numbers are out there somewhere. Yeah, it's not for me. It's not a make it or break it kind of feature. Now, OK, last question. If Spotify, if if someone were to come up with a service that would compel you to turn away from Spotify, can you can you imagine what it would be that they would have to offer you?  Oh, if somebody gave me this, I might I might stop. You know, I don't think so because the only thing that drives me nuts about Spotify is that they have a lot of great playlist features on mobile that don't translate over to the desktop client. And so I'd like to see that, but I have a feeling they're going to be fixing that or making them more widely available. They had these great daily mixes that aren't available on desktop but are like right on the top of your playlist for for mobile. But yeah, I mean, I can already download to my device if I want to. If I want to have things offline for for for playing when I'm not on the internet or connected for some reason, airplane mode, whatever. So I don't really know what that what that killer feature would be for me to make me switch. I think it would have to be more like Spotify would lose features for the tier that I pay for for it to really be an issue. I mean, I'm not I use it every day and I can't think of any reason why I what else what more I would need. I mean, it would have to be something pretty spectacular or free for me to make the switch. I think I guess price would really be the thing. Price is what Amazon is trying to tempt you with. Google actually and Apple both offer the ability to use those playlists across devices. Although with Google, it has to be in a browser and with Apple has to be in iTunes. But yeah, I don't I haven't seen anybody come up with the killer feature that makes me think, oh, the Spotify users are going to want to leave. It I think it would have to be selection. It would have to be some kind of a hit playlist.  But Discover Weekly is already so good for so many people. Right. Yeah, I don't know. That would be hard to convince even if it was true. And maybe it would be with ease of use data consumption. I don't know. I think it would have to be a new feature. Honestly, the more we talk about it would have to be something that we haven't thought of that we didn't know we needed. Or all of what I'm already getting, but literally free. But yeah, or or or like two dollars a month. Problem is that's not going to happen because the the music companies are only wanting to get more money out of these streaming services. They're they're not letting up the pressure. I'd be curious what the audience would would want to see if they can, you know, I as a product person, I can't even think of what I would want more if I were designing the product myself. So sometimes wisdom of crowds when you guys have a better idea. Yeah, send us your ideas. We want to hear not only how you listen to music, but what is that one feature that you would like to see in a music app that you're not seeing that would sway you to move, whether it's from Spotify or some other service to something else. By the way, you may have noticed it didn't disclose that my wife works in YouTube right there. She technically still does. But at the end of this month, she will no longer. She's changing jobs. She has a job. Don't worry. It's going to be great. She's very excited about it. And I will disclose that once that becomes a real thing. But yes, so technically my wife still works at YouTube for the moment. But she won't by December. Congrats, Eileen. Yeah, congrats. I'm very excited for a new job. And I can't wait for her to be ready to tell people what it is. Indeed. Let's get to our pick of the day from Soren in Denmark, who said, I just wanted to mention that I swear by freedom by F secure. I remember a while back, we asked people to send in their VPM picks. This is Soren. He says, I haven't done extensive research into the deeper workings of it. But F secure seems trustworthy, especially because they employ Miko Hipponen, who I respect deeply for his extensive knowledge of security. I, too, respect Miko. He's great. Also, they have apps available for all the major platforms, makes it incredibly easy to use the service, just the press of a button on my Android phone. It's not free, but it's also not terribly expensive either. I don't remember the exact price. By the way, I also just wanted to mention that I really appreciate the fact that you have started sending the summary newsletter of the week's most important stories. So it's great to catch up. That's awesome. So two picks for one. One is F Secures VPN. And the other is if you didn't know anyone who backs the show at the $5 a month level or more, gets a weekly summary of tech news and an original column post from me. Just about one of the issues we've been talking about. Thank you, Soren, from Denmark. Send your picks to us, folks. Feedback at dailytechnewshow.com. And you can find more picks at dailytechnewshow.com slash picks. Well, that is our Manic Monday. Ladies and gentlemen, Veronica, I'm very thankful you were here. Well, thank you for having me. And I wanted to say I had a very nice experience this weekend. Tom, I think I'll get a kick out of this. I met a young woman while she's, she's, you know, she's old enough to be gainfully employed at Google at this point. But she said that she went to college to get a CS degree because she was a buzz out loud listener. And she disagreed with me about something and wanted to be able to have the skills to back up her opinions about technology. And I was like, that's funny. I'm doing what I'm doing with Molly. So if you want to get into technology, find a woman who you disagree with and use that as your impetus to become informed about the topics you care about. What a positive use for the fact that there is no greater power than the urge to correct someone on the internet. I know somebody is wrong on the internet. I'm going to get a computer science degree. But I think it was it really warmed my heart and it was really nice to hear. And, you know, it's nice. I've had so many awesome role models in technology throughout the year. So it was it was it was just pretty pretty cool. And it gave me it gave me happy thoughts to think that people still remember Buzz Out Loud. Yeah, that's pretty nice. It makes me happy to affect Dr. Carl, who was once Carl the med student, had a picture on his Facebook this weekend and he was in his Buzz Out Loud shirt. It still hasn't fallen into tatters somehow. So that was cool as well. He never told me she never told me what she disagreed with me about, though. So I have to find her. I didn't I didn't get that part of the story. So I have to I have to complete the circle, have to know what it was and if she was right or if I was right, I'll never know. Yeah, maybe maybe she figured maybe finally after she got her degree, she she changed her mind and agreed with you. That's why she was. Yeah, if she has a CS degree, she definitely is probably more qualified on certain topics than I am. Well, thank you, Veronica. And I'm glad the toasters didn't come to get you Battlestar Galactica style. Yeah, so far, the building has not burned down. So I guess I'm in good shape. OK, anything else to tell folks about where they can find you? Um, yeah, robot.io is the company that I am doing product for. It's it's an awesome bot that lives in Slack and soon to be Microsoft teams as well in that launches. So we're working hard to to expand to other platforms as well. But if you want a cool tool for tracking team recognition, head over to robot.io. Thank you. And thanks to every single person who supports this show. You guys are the best.

This show is part of the frog pants network. Get more at frogpants.com. Diamond Club hopes you have enjoyed this program. All right. Good show. What should we call it? I like it runs on people. That's pretty funny. It runs on people. Kind of like two factors. Your real friend. Can you hear me? Yeah, it's going to burn people. First, do no harm. No harm. It's about more than just being friends. It's going to burn people. Oh, it's from Captain Jack. He just added the comma. Spotify. It's like Netflix for music. It's just true. Technically. The matrix was right. By the deep ether stream. Toaster fire. Toaster fire. Toaster fire. Deep ether stream. Toaster fire. That's for the fire. Don't cross the music streams. No toaster tech. Hmm. I really can't pick one. Yeah. Nothing. You like it runs on people, right? Veronica, you like it runs on people. I think that's funny. That one's winning, too. It runs on people. It runs on people. It runs on people. It runs on people. It runs on people. It runs on people. I love it. Good show. All righty. I'm going to head out. Thanks, guys. I don't know. I don't know. Is that the voice you use at the national voice? Yes. By the way, I started playing Civ 6. It's intense. It is intense. I started way too high level and I was just getting the poop kicked out of me. I went down to Prince or something just to get my bearings. I don't understand how they keep doing it.  There is a lot of it's smoother now. It's smoother and more complex at the same time. It made it easier for you to play to know what's going on. At the same time, it's like some of my old tricks from Civ 2 days, some of them haven't worked for a while.  My favorite thing is that you can link a military unit with a settler or with another non-military unit so they can protect them when they're going around. It's a good feature. And putting like locating the entertainment centers and the religious centers around the city. Super cool. I'll talk about this later. Bye. Too late now. What have you been playing? Music wise? Game wise. No. My GPU died. I can't play anything. I can play on the Xbox. You can play Civ on your laptop. I can. You have an Xbox. You have a TV. If Ellie is there. Brian talks about that all the time, how he can't use the TV for anything. Other than watching videos. Even when we watch his own shows on it, it's pretty much just for the kids. I split between myself, Jen and Ellie. I guess Ellie is still young enough. The problem with Brian's kids is that we watch a lot of SNL. That's probably okay. I watch 80s action movies which has explosions. That's the thing. All those 80s and 90s movies have a lot of blowing up people, but they don't have anything to replace them. You don't see them blow up. That was the whole thing about the A team. They could shoot people and it's like they were either the worst shots in history. You guys sure use a lot of ammunition for not doing anything. I think that's part of the problem why we were so desensitized. Because it wasn't realistic enough. That's the argument the PTA used against the Three Stooges. Kids see that. They'll poke each other in the head. Honestly, I not sure. I agree with that. A lot of the TV violent studies have been pretty inconclusive whether it actually raises aggression or not. I think it's like anything else. People have a predisposition to it. I think it probably has if we kept studying it, we'd have a lot of the probability. But only has a truly dangerous effect in someone who was already prone to it anyway. That's just a hypothesis. That's actually the truth. Hypothesis. I remember we studied this when I was in journalism school at UT. Most of the violence in children's studies were not as big as the one in the sample sizes. A lot of them didn't find any effect anyway. Of course, that was 15 years ago. That was 1994. Wow, that sounds like 20 years ago, isn't it? Yes. You know, it's weird because I remember when people used to say that when I was in high school, 20 years ago, that I was like, excellent. What did they say? It's loading so slowly. Come on, come on. Oh, it's about Patricon. Special thanks. We got a special thanks. Yay. Oh, this is their video. I'll have to watch this. They did a video about Patricon and they must have used me. My interview. I feel used in a good way. They were really like the three stooches growing up. I thought it was okay. I thought they were really boring. I preferred Abbott and Costello. It's not exactly the same thing as clowns, but it was a little bit like, I don't know. I liked Abbott and Costello. Laurel and Hardy were on the cusp for me. They were a little too dry. I think part of it is that Slapstick evolved in that. After Laurel and Hardy, where everything kind of had a rhythm to it. Abbott and Costello was part of that Saturday or Sunday. Actually, they might have been Saturday. Channel 11, they would show the Bowery Boys, Mom Pluck Kettle, the Abbott and Costello, and then often like a King Kong movie or a Fred Astaire movie or something like that. Yeah, like in here, they had the Abbott and Costello, but those are all right after the Saturday morning cartoon block. Yeah, it must have been on Saturdays. It couldn't have been Sundays because my dad would have been watching football. We had never seen him.  And then for fun, they might throw in a Godzilla or a Gamera movie. Right. Every once in a while, we'd get a good Godzilla for sure. Okay, so here, what's interesting is that was done because these independent television stations needed to find cheap content that they could afford to license and show. What would be the equivalent of those? Those things were at the time, what 30 to 40 years old in most cases. Yeah. 30 to 40 years. So this would be like showing 70s TV shows. So I mean, me TV is kind of like that. Yeah, yeah, yeah. I know like for a lot of on demand streaming sites they often backfill their catalog with stuff that's like pretty, pretty old. Yeah, because it's cheaper and they can probably get it as a large, like you can get our 50s collection. Although no one's done like a Dragnet or any of the big popular ones from the 50s. What's the one where he was the attorney? Perry Mason? Yeah, like shows like that. Those were pretty big ones. And Twilight Zone. Twilight Zone they used to have. They show that on sci-fi. I don't know if they still do. They used to. I guess you have to be really old to really appreciate Perry Mason. Not to mention knowing what we know about law, we would say, you know what, that's just a little too aspirational. We're too sophisticated for Perry Mason now, legally speaking. Too cynical. Like that would never fly. Objection, your honor. Perry Mason, if he had to face off and judge Judy's court. You know, one of these days we all be able to do virtual characters well enough that you can make that happen. You could. You could just feed in to machine learning all of the Perry Mason episodes and all the Judge Judy episodes and have it spin on. Invariably, they all turn out to be very unsatisfying. Like, not Judge Judy and Perry Mason, but like a lot of these mashups. It's a big thing with comic books now to kind of do that like, oh, let's throw it on the board. I think Star Trek Doctor Who comic. Yeah, exactly. Or Batman and whatever. And they always sound cool. Actually, a good one is the Predators vs. Aliens movies. Wouldn't it be cool if you get the Predators and Aliens? They never work out as good as you want them to because they just sound better on paper. Exactly. And I think part of it is a majority of those are kind of moneymaking. That's all they think of. It's like, well, we don't really want a sophisticated plot. We just want to shoot this. It's a lot of copies. Yeah. Just for a lot of tickets. You know, let's see a rival this weekend. I want to see it. Is it good? Is it as good as I think it's going to be? No, because I want to manage your expectations. But yeah, it was really good. I enjoyed it and I had read the short story last year for Sword and Laser. And so I knew the twists. I knew the turns. I knew what was going to happen. I still enjoyed it. Eileen loved it and she had no idea what was coming. So she enjoyed it quite a bit. I see that. Alien vs Predator comics were actually they were halfway decent. I would give you that. I think it depends because it was a pretty long line. Oh, Beatmaster. It said the Alien vs Predator comics were mostly awesome. The Dark Horse Act, that was one of the things Dark Horse did very well. It was to take movie licenses and make them into halfway decent comics. Yeah. I like that Marvel is putting out these Star Wars comics. I've been reading them a lot. But I do miss Dark Horse being involved with them. There is a tangible difference between the styles. Part of it is that Marvel not art style, but bringing unified storytelling parameter to all the comics. So even though you get different art styles, you get different story creators, but they are very obviously working within a shared universe. Whereas Dark Horse, I mean, for good or ill, I guess, let the reigns loosen a little bit. Well, they were allowed at the time, they were allowed to have an incredible amount of creative leeway. I mean, a lot of the stuff with the sith came through Dark Horse. The back history, I think that's what people like. All these things that are hinted at in the movies, you can finally understand and explore which is cool. I don't know, it's going to be weird. I'm wondering there's going to be there's going to be a level of landing I think is going to happen because they are trying to have a tough, tough task that they have given themselves to create quality stories in a 100% shared universe. I mean, even the Star Trek spin-offs were like, weren't they all sort of after the next generation crew, like after everyone moved on? Isn't that the whole reason why what's in the comics? No, the TV series they weren't all Yes, it was original series the next generation, then Deep Space Nine sort of was coincident with the end of next generation and coincident with the beginning of Voyager and then Enterprise was the first one that went back prior to all of the series. So Deep Space Nine, I guess in their universe would have been like 10, 15 years later? No, Deep Space Nine starts in season 5 of Next Generation like there's a crossover episode where Ensign Rowe gets off Deep Space Nine and they meet Cisco because originally Michelle Forbes was going to be a cast member and then decided she didn't want to get stereotypes or typecast. She was one of the best characters in Next Generation. She really was. And you know what's her name who's the character that replaced her? What's her name? Oh, on Kira? Yeah, Kira. It wasn't a satisfying She was good, but I don't know if it was the actress or the character though, because the character because she was Native Bajoran 100% was a different character than Rowe who had been a Bajoran with Federation loyalties But there's something about Rowe is very much like the school girl that like sneaks out to light a light to huff on a cigarette. Oh yeah, totally. That edge. It's just an edge of your character. They've done a lot to build that up. Alright, I think I've got everything published here. So excited to find out if I've accurately published the show. Bajoring Beatmaster says Bajorans were a boring culture. I didn't know too much other than their religious aspect and the fact that they built a spaceship that could fly with the solar winds. I thought that whole thing was a little much. Well, the whole Bajoran mysticism was the underpinnings of Cisco's entire storyline because he was the emissary there's the emissary to the wormhole aliens. Yeah. I always find that kind of where they wormhole aliens and not just beings.  Like, aren't the dominion the alien the empire? Alright. We'll leave you, we'll leave the solution to that problem as an exercise for the listener. Thank you everyone for watching. We'll be back with Patrick tomorrow. Goodbye.


This is the beautiful city of Barcelona. Welcome to you all, Martin Tyrone, Alan Smith, new commentary of El Clasico, and it should be beautiful football played by both Barcelona and Real Madrid, Alan. Yeah, and what a privilege it is to be here, Martin. Couldn't get a ticket for London Money in the town today. This is going to be a classic, another El Clasico, I'm sure. Griezmann. He wants to run at them with the ball. It's good to see. Cross towards Messi at the near post. And that's into the gloves with the goalkeeper, not the hardest thing he'll have to do today by any means. Sergio Busquets. Now it's Suárez. Got in the way. Here's the home team lineup. Marc-André Testeghan starts in goal. Nelson Samedo starts with Jordi Alba as the fullbacks. Ivan Rakitich plays with Sergio Busquets in central midfield. Luis Suárez is the lone striker today. This is the Real Madrid lineup. Tiba Kutwa starts in goal. Sergio Ramos plays with Rafael Varan in central defence. Eden Azar starts with Nisius Jr. They'll play wide. Karim Benzema is the lone striker today. Azar was a foul. The referee's seen the situation and he can play off. Good work from him. Eden Azar is offside. Samedo. Ivan Rakitich. It's messy. Well, the special talent on view today. We've got Lionel Messi against that Eden Azar. What do you think about that, Alan? Wonderful to watch when these two are on song and I hope they are today because if they are, they are going to give us a real treat. Messi. Corner to come now. Come in from the corner. Nelson is with them. They've created chance after chance. He will do well to reach it but he couldn't keep it. Now Casimiro. Able to intercept here. Messi. Not really tested the goalkeeper but sometimes... The Barcelona shape looks like this. Marc Andre to Stegen starts in goal. Piquet starts alongside. Climo Longuele in the centre of defence. Luis Suarez will be the main striker here. Dicepbe. Ray on the drix side. Luka Modric plays with Tony Klose in the centre of the park. And leading the line today is Karim Benzema. Well, they've lost it. It's his dear devil style of attacking. Could well make the difference here, Lee. Well, his ability on the ball is second to none. Just watch how close he keeps. And he's broken free. That again, once he gets into his stride, he just strolls past players. What a lovely turn to do it inside your own penalty area. Down the short. A fairly routine for any goalkeeper. It's a Barcelona corner. And Sculpt from the cross. And it's a verbally to take back possession. It's the high pressure, high intensity approach. Goodness, he was right on top of the situation to get them all back for his team. Messi, highly promising but they got nothing out of it. Could they make something happen? And the throw in forthcoming.


You know this thing that returns an AI-generated image from keywords? It should probably show an ROG Strix Scar 15 when given the word's gaming laptop. Yes, this is a classic. The latest iteration is called G533, and it has everything a gamer might need, kitchen sink included. Tag along as we give you a quick tour of the new Asus ROG Strix Scar 15 G533. As expected, the built quality is top-notch, with a combination of plastic and aluminum that is very tough, thanks to the structural supports on the inside. The design includes a transparent part of the base and an RGB backlit ROG logo on the back. Then we have the signature armor caps, which you can customize through Asus's website and 3D print later. Asus borrows tech from its productivity and business laptops, sacking the traditional numpad and integrating it into the touchpad. The keyboard has 2mm travel distance and per-key RGB backlight, controllable via the Aura app. Going to the sides, we find two full-sized plus two Type-C USB ports, one of which is Thunderbolt 4. There's also an HDMI 2.1, so you can connect an external screen with 8K resolution or a 4K one with a 120Hz refresh rate. The LAN port has a bandwidth of 2.5 gigabits. There are two displays to choose from, both supporting Dolby Vision HDR and Adaptive Sync, 300Hz Full HD or 240Hz QHD. We chose the latter for our review and we could totally recommend it since it has high maximum brightness, good contrast, and full sRGB and DCI-P3 color coverage. In other words, expect a cinema-grade picture quality, and it's really immersive thanks to the thin bezels and the quad-speaker audio setup. By the way, you can play as much as you want since our tests show no PWM across all brightness levels. Such a screen, in combination with powerful hardware, often leads to short battery life. Not this time, the G5 33 has a 90Wh unit that manages to last through 11 hours of web browsing or 7 hours of video playback. The ROG Strix SCAR 15 G5 33 is well-future-proofed, with two Sodom slots for DDR5 memory, plus two M.2 PCI-X4 slots with support for Gen4 drives. Of course, these are the latest-generation modules. Although the G5 33 can be ordered with up to RTX 3080 Ti, we decided to test a more affordable configuration with the 1.5-bit G5 33. It's powerful enough to run games like the Witcher 3 at ultra settings, with about 150 FPS on average. You can bring up the resolution to QHD or 4K, and still get good frame rates and smooth gameplay. All configures are available on the G5 33, and the G5 33 is available on the G5 33. As for the cooling, there is one heat pipe shared between the processor and the GPU, with two more dedicated to each of them. They are connected to four heat sinks, where two arc-flow fans dissipate the heat. A sixth heat pipe is also available on the G5 33, and the G5 33 is also available on the G5 33, and the G5 33 is also available on the G5 33, and the G5 33 is also available on the G5 33, and the fans dissipate the heat. A sixth heat pipe is cooling the graphics memory and the VRMs, while the CPU sports a liquid metal thermal compound. This is a beast of a setup, as you can see in our temperature test. The Core i9-12900H in our configuration runs its P-Cores at nearly 4 GHz for the entirety of the test, while the E-Cores barely drop below 3 GHz. All of that by sustaining 121 Watts in long runs. Incredible! There are no issues with the GPU cooling as well. The G5 33 keeps its max TGP. Our opinion is that if you can afford it, the Scar 15 should be on your shortlist, as it provides great qualities for both gamers and creators, and looks unique while doing so. Top notch CPU and GPU performance, professional grade display, strong construction, and stacked with RGB. Do you need anything else? Of course, we can't leave it without cons, so we'll mention the lack of a web camera and SD card slot, but we know that most gamers will not even notice their absence. That's why we're awarding this notebook with our Editors' Choice Award. Of course, we've done a lot more tests, and you can check out all the results in our in-depth review on laptopmedia.com. You'll find the link in the description below the video.


So far we have derived the scattering amplitude for zero Kelvin lattice. Then we went ahead and evaluated the scattering amplitude for finite temperature. Then we introduced the energy conservation through a delta function and derived the time correlation which is correlated to the double differential scattering cross section for a scattering system. Now I will introduce you to the correlation functions in space of real time and real space to q space and to q omega space which is important. Because many of our experimental results sometimes we will be talking about the real space, sometimes we may talk about q space and their correlations and sometimes in planning of the experiment sometimes will depend on this with this as start or lecture 5. So we have derived the scattering law of a system. By scattering law what I mean is this. I wrote d2 sigma d omega d prime sorry this will become a E prime is a Fourier transform over sum over jj prime vj vj prime q and then there is a statistical average and sum over all possible sides distinct and non-distinct. So we have derived the scattering over ensemble average with the where we have used the statistical average. Now as a simplistic assumption if I take away the side dependence of the potential if I say that all the potential all the sides are same then this part I can just take out of the summation and it is k prime by k because of the flux normalization and I can write as average of v square q I am sorry it is not it is slightly wrong. So I was writing d2 sigma d omega d E prime and this comes out as I have one v square q when you take away the side dependence average value of that of the potential it comes out of the summation series its average over that and also we have got a summation over jj prime of an ensemble average of v to the power minus iq dot rj0 a time correlation function which is averaged over all the possible values of energy with the statistical weightage which is p lambda given by p lambda beta is 1 by kT Maxwell Boltzmann distribution and partition function is z. So with that we can write d2 sigma by d omega d E prime as n into k prime by k m by 2 pi h square square v square q sorry that v square q multiplied by the factor sq omega sq omega is known as scattering law for the system its expression is this 1 by 2 pi hn Fourier transform over this statistical average of correlation function at time t. So this is actually q dependent and we take away the time dependence over a time Fourier transform I get the q and omega dependence. Similarly from this sq omega this correlation function if you go in the other direction from q space if I try to go to r space again I have to put a Fourier transform and I have to write and I can go to real space also from the q space but then I have to integrate out I will take away all the constant factors I have to do an integration over q space and then I have to write down is the ensemble average of that and you have to do a Fourier transformation over q now so that means I was in momentum transfer and time space if I go do a Fourier transformation over q I go to real space and time similarly if I go and do a Fourier transformation over omega where h cross omega is energy transfer I go to an omega space and if I do a Fourier transform back on time I go to iqt from here. So this is an interesting way of looking at our data we collect our data in sq omega space our data we collect in terms of not sq omega sq omega space in terms of scattering log for a system which is a function of q and omega. For example for a diffraction experiment we know q is equal to 4 pi by lambda sin theta so this is the momentum transfer and we know that we collect the intensity as a function of q we get this kind of Bragg pic which I showed you the Bragg pic so this is in q space and we get intensity as a function of q from here if you want to go to the real space I have to do a Fourier transform I can go to g of r correlation functions in r going one step ahead for inlustric experiments if I am in real space one Fourier transform will take me to on r will take me to q space and time space one more Fourier transform will take me to q space and energy transfer space. So these are the correlation functions in q omega space qt space real time and momentum transfer and this is the physical system whose expression we are seeking. So this is known as a greens function when you go to real space and time which is a Fourier transform over q d3q q to the power minus iq dot r of the correlation function summed over all the sides this is what is interesting in this derivation. So now the prescription for real space and time to q omega space is Fourier transform over energy and momentum. This is what I have written down here that sq omega is a double Fourier transform I am sorry it is d3 here also you can write so this is so I have one Fourier transform over space and another Fourier transform over time to go to scattering law space q in q and omega to n omega. So now I have written it down specifically here that I have sq omega iqt and g of rt and now I can tell you that if I just talk about a diffraction experiment in many ways I can do it. I can do it by setting omega equal to 0 then it will be sq omega equal to 0 and I can also do it as an integration over omega and these two I will take up in the next part of my lecture.


Prusa Slicer. Is it the best slicer for 3D printing? Let's take a look. My name's Jim and this is the edge of tech. So I've been using Prusa Slicer since July of 2019. I've pretty much swapped all of my printers over to Prusa Slicer now. I really really like it. Now I really liked Kira as well, but Prusa Slicer is super simple to use. It's very easy to configure and I just love the quality of the prints that I got from it. So I slowly started bringing all of my printers over to Prusa Slicer one by one. Today we're going to go through, install Prusa Slicer, configure it for the first time, set up this Ender 5 Plus as a printer inside of Prusa Slicer. You could do that for any printer. You just need to change your bed size and your build volume, which is not that big a deal. We're going to go through adding a print. We're going to go through all of the configuration and I'll show you all the different tabs. Prusa Slicer is really cool. So it has beginner all the way to advanced modes. So you can see little tabs if you're starting out or you can expand it to see all the advanced stuff in the advanced part. It's real easy to use. We're going to walk through it step by step. I'm going to show you how to do it and by the end of this video, you're going to have your first printer set up on Prusa Slicer and ready to slice a print. If you've ever wanted to stop your print and change the color once or even multiple times, Prusa Slicer makes it really easy to do. If you need to throw magnets in your print, maybe you need to pause, throw a couple magnets in and then keep going. You can do that too and it only takes two clicks. By the end of this video, we're going to have you up and rolling and you're going to be able to use Prusa Slicer like a pro. In the description below, you're going to find everything you need for Prusa Slicer and I'm also going to throw files out there for some of my printers to get you started with a profile you can begin with. What I would do is take those profiles and use them as a starter profile and then build off of them. Dial your printer in using the steps and the settings we're going to go through today. That way your printer prints awesome too. Well, I think it's about time to do it. Let's roll. So the first thing we want to do is install Prusa Slicer by going to prusa3d.com forward slash Prusa Slicer. Right in the center right now, they have the download latest version, but I like to go to software, drivers, firmware and manual just in case that button is not in the center in the future. Right here in the center, you'll see all the different versions you can download. I have windows, so we're going to download the windows one right here. When it gets done, run it and you'll see these settings here. Now, I like to use all printers in mine and I just hit next. Yes, I want a desktop icon hit next and then hit install. When you're done installing, you'll get the icon on your desktop and double click it. When it opens, you'll get this window right here. It's the window that opens when you first open Prusa Slicer for the first time. We hit next on that window. The next window here takes us to all the Prusa printers. If you have a Prusa printer, this is where you want to choose which printer you have and which one you're going to print with. I don't currently have a Prusa printer, but that's okay. We're going to hit next. If you have a Prusa SL1, you can choose it there. I'm using the Ender 5 Plus, so we'll choose Creality under other vendors. The one they have in here is the Ender 3 and I'm going to leave that in with the .4 nozzle, so we'll hit next. What I want to do is set up a custom printer. We're going to define a custom printer profile by clicking this little box right here. Once we click that box, we're going to actually go down under the custom profile name and give it a name. In my case, I'm going to type in Ender 5 Plus because that's the printer we're going to add. Click next. What type of firmware we are using? Marlin, so you want to choose your firmware. I use Marlin, so we'll hit next. Now we're into the bed size. In the Ender 5 Plus, we have 350 by 350 by 400, so we'll type 350 and 350 in there. It is rectangular. I don't have any texture files or any model files to load. If you did, you could actually load those here now, but I don't have any. This is good. We're going to go to the next screen. Once we get into this screen, we want to tell it what nozzle size we have and what filament diameter we're using. In our case, .4 and 1.75. The next is going to be the extruder and bed dumps that we want to use for our filament. In my case, I like to start my co-exit about 210. I usually print it at 220, but I like to start at 210. My bed temperature at 60. We'll hit next. This is where you can add in pretty much any of the pre-loaded profiles for filament. You can check them all here. When you choose the different generic Prusa or Creality printers there, it will actually show you the different types of filaments that are pre-loaded here. You can actually go down right here and click all as well and then hit next. I like automatic updates to check and I like the automatic built-in presets to update as well. I'm going to leave those checked there and click next. Reload from disks. You don't have to do anything from here. If you want to reload, you can, but that doesn't have anything to do with our setup now. The next thing is your view mode. Remember, I talked about simple all the way to expert or advanced. What I'm going to do is put it on expert to show you all the settings. You can leave it on simple or whatever you want, but I'm going to leave it on expert for now. Hit finish and that's it. Now that the initial config is done, this is your build surface in Prusa Slicer. You can drag it and move it around just like any other slicer. We're going to go up here to print settings to start though. This is where we look at all the different printer settings and I'm going to start on the general tab. One thing we need to do is change the Z height, so the max print height to 400, because that's what our Ender 5 Plus uses. As you can see, the 350 by 350 is in here because we set that earlier. We can go down the list. We don't need to change the Z offset or extruders or anything else in here, but you can go through it and check it out if you want to change anything, but it's all pretty easy stuff. Now, every section I do, I'm going to save. Hit the little button there and then click save. We'll go to custom G code. This is where you can add your starting and ending G code. I'm going to add some custom start G code because we need to add the G29 for the Ender 5 Plus because it has the BL touch. This is the G code I use on all of my printers currently that have ABL on them. I copied and pasted them in. Like I said, the G29 is in there. Then I can put that in the file in the description below as well. The End G code, I'm going to paste mine in as well. I'll copy that and paste that in right here. This is the End G code that I use on all my printers as well. Take the space out of there. Now my start in End G code is in. I should be set and I don't need to do anything else so I'm going to save it. The next thing I want to do is machine limits.  This is the settings I like to use so you can pause your screen and check these out. I just saved those. I like to spare a little time so you don't have to watch me type them all in. Extruder here is what size nozzle, your layer height limits. Your min, your max, all that stuff. Your retraction is down here. I'm going to change mine to five for my under five plus. We might have to dial that in a little bit but I started five on all my new profiles. You can go through and check any of these. Don't forget to save. All that is good. Now notes. You can type any notes you want about this printer in this section and then this tells you any dependencies on all of that section. So we can keep moving. There's nothing special there. This section is your filament section and it has everything to do about all of your filament. So we start at the top with the filament tab and we can go through and right here is your extrusion multiplier. This is the same thing as flow rate in Kira. So if you need to change your flow rate, maybe you did your E steps and flow with the video I have. This is where you would do it in that extrusion multiplier there. You can do color. You can do the cost of the filament. Maybe it's $20 a kilogram so we can throw that in there. You can change your temperatures and all of that. So we save that. We can go to cooling and I like to keep my fans always on. So I just do that because I print mostly PLA. So I want to check this box right here to keep my fans always on. The next cool feature is auto cooling and you can see that right here. Now auto cooling will vary your fan depending on the print and you can read the little blurb about it right here if you want to. But I like to use it but I like to use it a little less drastic at 80 to 100%. You can change it as much as you want but that's where you do change it. I save my settings and I move to advanced. Once you're in advanced you can actually do a lot in this tab. You can change the type of filament you're using by any of these right here. You can change the speed. Maybe there's a speed override you need. Any of the speed settings or cooling or anything like that with like cooling moves and stuff is going to be down there. We're going to hit save because I don't need to change anything and go to filament override. Now I don't change any of the filament overrides here. You can see there's length and there's a lift of Z. But if you have a special filament maybe you need to change this. You can do that there. Another custom gcode tab. Some notes if you want to take notes on this specific filament and dependencies. There are a couple on this one. Nothing special we need to look at. The next one I like to look at is the print settings. This has everything to do with all of your different print settings. So we're on the layers and perimeters tab and we can change this. I'm going to go to 0.12 just for the heck of it. This is your first layer height. You can actually change this to a percentage. I like to do mine at 105%. So if you click over here it'll ask you if you want to go to percent instead of millimeters. You say okay and it'll change that to 105%. You can do millimeters or percent whatever you prefer. Three perimeters is your walls and Kira. I don't mind three in this case. Why not? If you want to do vase mode that's spiralized vase and then down here are the solid layers. So the top and bottom. There's a lot of extra stuff down here with perimeters and your Z-seam. You can do a random or nearest or lined or rear. I like to keep mine aligned and we'll go to infill. You can change your infill right here to make it anything you want. You can change the fill pattern. You can do top fill, bottom fill, anything you want to do right in the section here. There's a ton of features you can just walk through them and if you hover over them they'll tell you what all of them are. So we save if you change anything. If not go to skirts and brim. This is where I like to do. With the Ender 5 Plus I'm just going to do one loop for a skirt because it's quite a big bed. And six millimeters away is fine. If you're going to do a skirt you can change this to the height. I'm sorry to one layer and that's what I like to do is just one layer on that. And if you're going to do a brim is what I meant. You can change it here. The next one is support material. You can hit this to generate supports or you can take that off. There's auto-generate supports right here. There is raft layers. There's all sorts of different options that you can do that I usually don't play too much with on a normal basis. The next one I like to look at is your speed tab. This is where you can change your speeds for pretty much everything for your infill. These are the settings I like to do. You can see them in the orange. You can pause your screen and see those and then we'll hit save and go forward. Multiple extruders. I don't have multiple extruders so we'll just leave most of this default. But if you did you can change it all right in here. Maybe a little ooze prevention or have to do with the wipe tower. All that is right in there. So I don't do anything there but that is where you would find that setting. So the next one is advanced. You can do everything you need to do with extrusion widths, overlaps, flow, some more slicing things like if you have a gap or maybe a resolution or an elephant foot compensation that we're going to talk about in a minute. But I like to do a little bit of changes and you can see those there. So this one right here is your output. I don't do anything with this tab. Notes again. You can take notes and hear your dependencies. And once you walk through all those I'd save that and you are done. Now across the top here we have a simple mode. As you can see you got rid of some stuff and I'll show you that here. It definitely gets rid of a bunch of those tabs and this is perfect. If you're just starting out you don't need to see all those tabs. If you click expert it adds quite a few more options in there. So if you want to use simple mode go for it. If you want to use expert that's okay too. Let's load a print on here. So I'm just going to go into my 3D prints and maybe just grab something quick. Maybe this AA battery holder like this right here. And as you can see it drops it on the plate. That is a really cool thing. You can move it around at the top here. Here's an auto center or an auto placement button. So once you move it all around there you can click this and it'll actually center it back. If you click this button you can actually multiply many times and then recenter them like that if you want. I like that there's a back button right here and there's a forward button if you want to redo. So you can undo and redo things if you messed up which is really cool. So once you get it all set maybe you want to tip it sideways. So go over here to rotate maybe tip it over this way or that way. And then maybe turn it a little bit here. You can do all that. One of the cool things is to place flat on face. So you can hit that button and click any of those highlighted areas and it'll go flat on that face. Maybe center it again. On the right side you'll see supports. You can do build plate for enforcers only or everywhere. And this is your infill percentage over here. If you want to brim you can click that little checkbox there. Down here is where you change the print itself. So maybe we want to go to 150%. We can do that and make it bigger or smaller. You can do anything you want to do and then hit that little slice button and you'll see it exported. It's going to take five hours eight minutes or if you have stealth mode four hours 58 minutes. You can hit export and then save that. I loaded a new print here to show you some really cool things. We can walk down through the layers after it's sliced and this is a little bit bigger print. But if you click this button on any of the layers it'll actually allow you to do a color change. And if you right click it you can change that color. So maybe I want to do a yellow and a blue moai. So I go to that layer. I hit the color change and then you can see right in the slicer what it's going to look like. Maybe we want to do another one right here. So hit it again and then right click. Oops, my bad. Right click there and maybe we want to use pink. Now how about red? Let's use red. We'll click OK. And then next thing you know you have a three color moai. And that'll actually automatically stop and pause the printer so you can change the filament out at that layer. Go down here and hit that slice button again and you can see what it looks like fully sliced as we pull it down. And that is a really cool feature that's built right in. I really love that feature. If we want to add something like a magnet so you can come down maybe one of the first layers. Click over here again and then click pause print. Then you can actually put a note in so this will actually tell you on the printer place magnet in base. So at that layer your printer will pause. It'll tell you it should show you that blurb that you just typed print magnet in base. And you'll see a gray line right here where any pause is. So that's not a bad layer. That's actually a pause line. You can hit slice again and that'll slice that pause in and show you the whole thing completed. And that's a pretty cool thing. I really love these features because it makes it real easy in the top left here. You can actually see the pause and then all three colors at what layers they're going to pause to let you change the color out too. So that'll show you that in the top left and it's just a really cool interface. I sliced this again and we have a little elephants foot so I think we should fix that. So we go to print settings advanced and you see an elephant foot compensation right down here. Now by default this is turned on to 0.2 but you can take it away. You can add or subtract more if you want to. But I wanted to point that out that it is by default turned on at 0.2 and that's a really cool thing. The next thing we can do up in the top right is these are all different. The settings, your filament is right here and right now we're looking at the Ender 5 plus filament because that's what we loaded. But why don't we change that? So we go into your filament settings. We click that little gear. It'll take you straight there. Maybe we want it 220. Maybe we want it a yellow filament. So we click yellow. We hit OK. And now we have a yellow filament at 220. And you know what? We're going to save that under a different name because this yellow filament is totally different. So we'll call it yellow filament. It can be maybe Creality. We'll call it yellow Creality. How about that? And it's PLA so we'll put PLA. We'll hit OK. So now we have a yellow Creality PLA filament right here in the settings. So we can bounce back and forth between any filament you load in here. You can actually do that with anything in this section. So once you add the yellow or any other colors in, it'll see it there. And you can add printers and print settings the same way. So I want to click on... Why don't we click on the Ender 3 here? And we can actually go into Filaments. And you can see all the Creality presets that loads when you click that preset for the Ender 3. Maybe you have a PETG you want to run for generic on the Ender 3. You can go in here and see actually what settings are running for PETG. You can change the color. You can see they're using 240 and 70, which is good. So as you can see, the Moai is on an Ender 3 bed now. But I want to create an Ender 5 profile. So I'm going to click the gear next to the Ender 3 and go into the General tab. And we need to make some setting changes for the Ender 5. So maybe we go up here to Set. We change this to 235 and 235 for the X and Y. And then we're going to hit OK once we get that done. And we're going to change this to 300 because that's how tall the Z is on an Ender 5. Then we're going to go up here and hit Save. And we're going to change this to Creality if I could type. We're going to change this to Creality Ender 5. And that's going to save that Ender 5 preset. It's going to save that Ender 5 preset right in your presets now. We have an Ender 3, an Ender 5 Pro, and an Ender 5 Plus. That is how easy it is to add printers in Prusa Slicer. It's so easy. Once you get your settings, you may want to import or export. By doing that, go up to File and Import or Export right here. If you want to import a config bundle or a config file here, you can do that. Or you can do the same thing for exporting a config or a config bundle, which means the print settings, filament, and printer. That's a pretty cool thing. We go back here to this. I want to show you right down here in the corner. You can click this little icon here and save it directly to a SD card or a microSD card that's in your computer. I thought that was a really cool feature. If we go back to the build plate and you go to Help, there's some really cool keyboard shortcuts too. So I wanted to point this out because not a lot of people know that Prusa Slicer has the keyboard shortcuts. If you look through here, you can kind of study what they are and use them how you want. And I think it's a really cool feature of Prusa Slicer. Just another really cool thing that they add in. And that's about it. So that's it. We're done. We actually set up Prusa Slicer. We configured it for an Nr5 Plus. We configured some filaments. We walked through a whole bunch of settings. We've checked out some of the really cool features, including adding different colors in a single print. And I think you're on your way to using Prusa Slicer from now on. As far as it being the best slicer for 3D printing, I think it is. But I think you need to try it, even if it's just one print or a couple prints to dial it in. And then let me know in the comments what you think of Prusa Slicer after you set it up for your printers. I mean, it is real easy. If you have an Nr3, the profile is already there. You just take their profile and you build on it. Don't forget in the description below, there's going to be a link to a couple of my profiles that you can use. So feel free to check those out.  Remember, Prusa Slicer is free and free is good. Joseph Prusa and the team over there do a really good job of keeping it updated, of throwing out release candidates for everybody to check out, and then adding features all the time. Well, I hope you learned something today. And as always, keep printing.
