Hi, this is Allison Sheridan of the NoCellicast podcast, hosted at podfeed.com, a technology geek podcast with an ever so slight Apple bias. Today is Sunday, February 12, 2023, and this is show number 927. Well, we got a big show for you this week, so let's jump right in with another interview by Bode Grimm, the awesome host of the Kilowatt podcast. That's a podcast you should go subscribe to, of course, when you're done listening to this show. Anyway, the Kilowatt podcast is a show all about electric vehicles and alternative energy. Now, the interviews he got us from CES have nothing to do with electric vehicles. They're just things he thought would be fun for the NoCellicastaways. Hey, everybody, Bode here, and I have a really cool interview for you today. Honestly, this is not a company that I would normally cover on my show or just in general, but it was such a neat demonstration that I decided to ask them if they'd be willing to be interviewed, and they were. And that company is Tonys. If you don't know or have never heard of Tonys, like I was a week ago, Tonys is a really cool tech device for kids three and up. They provide screen-free entertainment for kids. The Tonys device is a speaker that allows children to independently listen to audiobooks or age-appropriate songs. There are two parts to the Tonys system. The first part is this really cool, soft, squishy, huggable box, which is equipped with Wi-Fi and, like I mentioned, a speaker. And it's got two little ears on the top, and those ears are used for volume control. And also on the top, it has this little lit-up square, and that brings us to the second part of the Tonys system, which is the Tonys itself. And these are just little figurines equipped with RFID. And the child just puts the figurine on the top of the box, and then it plays the content for that figurine. I got to interview Cole from Tonys, and he is going to explain all of the features of this device. All right, I'm here with Cole, and Cole is with Tonys. Could you please tell me what Tonys is? Yeah, so Tonys is a squishy, screen-free audio speaker. It's designed for kids as young as two years old to play with all their favorite characters, whether it's a Disney princess, Sesame Street, Paw Patrol. And all you do is you put your favorite character on top of the box. I'm putting Peppa Pig on top of the box, and you'll start hearing Peppa Pig. Peppa Pig is going to play music, audio books, stories, and educational content, and you work it by pressing the big ear to turn the volume up. Volume down is the little ear, and it's entirely tactile, so a two-year-old can work this without any help from mom or dad or grandma or grandpa. And so if you want to change tracks, you just slap the side of the box. If you want to fast-forward, you just tilt the box to the left. If you want to go to the right, it reminds it. And then there's a headphone jack as well. Yeah, I saw that you have branded headphones out there. In addition to the regular headphones, you can just plug in with it. Yes, so any headphone will work with the box. Ours are built so it's got a lower decibel rating, so it's not going to hurt a developing child's ear. One-year-old to two-year-olds can wear headphones and not worry about volume hurting them.  Because I'm almost 50 years old and deaf and it still hurts my ears. Absolutely. That's cool. So you have some branding here. You mentioned Peppa Pig and Paw Patrol. You have Disney branding. What else you got here? I can certainly mention we have these, they're called creative Tonys. So these Tonys that are in white packaging and they have little ears on them. And these come blank. So we have a My Tonys app and we have a lot of grandparents, whether they're, I have a grandparent who lives in Minneapolis where I live. Her grandkids live in South Africa and so every morning she records a new message on her phone on her My Tonys app and she says hi to her grandkids and her grandkids wake up in South Africa, put the Tony on top and they get to hear a new message from Grandma and Grandpa every single day. And that's because this is Wi-Fi. This is Wi-Fi. I don't know if we mentioned that at the beginning. It's been a long day. Yes. But that is so neat. So every single day, I was under the assumption when, I forget her name. I was just talking to her, I'm so embarrassed. She was very nice. When she mentioned that, I just assumed that it was like a one time thing. So if you're a grandparent, you live in a completely different continent. You could say hello to your grandkids. That's right. And we have a lot of parents who are maybe military parents or we have certainly at this company salespeople who are traveling away from their family using that My Tonys app to always send a message to their kids back home wherever they might be on the planet is a great way to stay in touch and to stay engaged. And then the kids have the agency. So this is something that they use all by themselves. This is their box. And so they can always listen to whenever they want that new message from Grandma and Grandpa and they don't have to wait for a face time. They don't have to wait for a phone call. They have complete autonomy of when they want to connect with their grandparent, relative parent, what have you. Man, that is so cool. I'm telling you, this is the design is very kid friendly. It's just a cube with a green box on the top where the kid puts the. What did you call the Tonys Tony? And then it just plays the the minority book that's in between 30, 90 minutes. Yes. So every character is going to be anywhere from 25 minutes to three hours long depending on it. So some of them are just audio books like our Shrek or Peter Rabbit, which is just an audio book experience. Some of them are just music like Coco Melon or Counting Songs Tony. But the majority of our figurines are going to be a mix between audio books and music. And then how much is the cube and then how much range wise are the Tonys? Yes, great question. So the Tony box is 99 99. It comes with a figurine right out of the box. So it's a great value right out of the box. And then all the figurines themselves range anywhere from 1499 to 1799 or 1999, depending on how long the content is for each character. And so also we like to say at Tony is when you're listening to audio, you're tuned in. When you're watching a screen, you're tuned out. So you're allowing kids to think for themselves what a fire truck might look like or what a story might unfold in their imagination compared to the screen type of entertainment. Thank you so much. Tell people how they can buy one. Yeah, absolutely. So you can go to your local Target, local Best Buy. You can go to Amazon and you can go to Tonys.com or the kind of main distribution. But if you have independent toy shops in your local geography, our independent toy stores will be happy to see you as well to look for Tonys. Awesome. And that is it. Thank you so much. I appreciate you. Thank you very much. I want to thank Cole for agreeing to be interviewed. It was definitely the end of the day at CES. And everybody was tired and ready to go home on a Saturday night. So Cole was very nice and stayed a little bit to chat. So I appreciate that. If you want to learn more about Tonys, go to Tonys.com. Well, thanks so much for this, Bodhi. What an inventive toy. I just love the idea of being able to send an audio message to my grandkids every day. I have a couple of granddaughters that are turning three very soon. That might be on my list. But also one of my granddaughters is absolutely obsessed with Coco Mellon. So she would really love what he was talking about there. I have a feeling the feature she would love the most would be slapping the side of it to change what it's playing. In October, I had a gentleman named Darcy Hegerty on Chichat Across the Pond to talk about the process he uses to create video screencasts for the video tutorial podcast, Screencast Online. I wanted to talk to him at the time about his methods because he created a process that is vastly different from how I normally do mine for Screencast Online. For my last few tutorials, I have followed what I'm calling the Darcy method and I have some observations about how I'm actually liking it better than my own process that I've been using for years. So before I can explain why I liked his method better, I need to explain the differences in our workflows and I'll start with mine. For at least a week or so before I start recording, I test every single feature of the software I'm going to teach. As I poke all of the buttons, I keep a mind map open in the awesome IThought software. I throw concepts onto the mind map with brief explanations of each one. As I start to get a mess of nodes, I then start to organize them in order to kind of tell a story. For example, I might decide to teach an entire tool and then march through its settings at the end or the tool might be better explained by jumping in and out of settings as the need arises in the use of that particular tool. When I'm done working out the story I want to tell, I make sure to flesh out any details I didn't already understand. I write a little bit of the intro and then I start doing my recordings. Now we use ScreenFlow as our recording, editing, and producing software for Mac apps, but iOS apps are actually more reliably recorded using QuickTime. ScreenFlow can record iOS devices, but as a collective, the screencasts online tutors have found it can be kind of hit or miss on how well it continues to work when you're trying to do these recordings. So for iOS, we record in QuickTime, we import the file into ScreenFlow, and then we separate the audio track from the video track, and then we go to town editing. Now I'll describe the process for MacOS as it's easier to explain the Darcy method differences if I stick to just that one platform. I also need to explain the geometry of how I work, because it highlights some of the advantages of the Darcy method.  My microphone is on a boom arm that comes out diagonally between those two devices. When I'm recording, I set the MacBook Pro as the primary display, and I rotate the microphone so I'm speaking into it at the correct angle. It's not the most ergonomic positioning to sit at my desk, because I'm kind of crooked over at an angle, but since I do the editing on the big display, I'm switching back and forth enough that I don't get that crook in my neck. Now on the big display, I've got ScreenFlow taking up the left two-thirds of the screen, and the right third is the mind map. I look at the mind map for a very small section of what I want to demonstrate, maybe practice it once in the app, and then I hit record for both audio from my mic and video from the Mac's internal display. I can usually only do like three minutes max before I have to stop. ScreenFlow asks to import the clip and name it on import, and I need to choose whether to drop it in immediately or drag it into the timeline manually. Now you might think it would be good to just jump right back in and keep recording to stay in the flow, but I tend to edit the shortcut right away, especially when I'm doing Mac recordings. The problem is if I record too much, it's not uncommon for the screens to change significantly, so going back and doing a re-record of a small piece if I find a mistake is impossible. Now I pride myself on the fewest number of page curl transitions to cover up moving items on the screen, so that's one of the reasons I do it in small chunks. I do a chunk, I edit, I chunk, I edit, I chunk, I edit. So this means the process is to review the mind map, record a couple of minutes, edit a couple of minutes, review the mind map, record a couple of minutes, edit a couple of minutes, and so on and so on.  Once I step away from recording, it's really hard to get back into it again. I've recently gotten a new interface for my big girl microphone, the Elgato Wave XLR. My previous USB interfaces were too slow, and I used to get pops and clicks because it was too slow, so that meant constant voiceover recordings were required during the editing process. Now, while the Wave does a much better job, I do get the occasional pop or click. I also get road or airplane noise that I didn't notice while recording, so those require a voiceover recording as well.  As I mentioned, the mic is on a boom arm between the big screen and the laptop to my right. I record video and audio looking at the laptop screen, so the mic is slightly to my left, but when I'm editing, it's on the big screen and the mic is now to my right. Now, when I do this switch to go over and start doing these voiceovers, I try to position it the same distance and angle as I flip back and forth, but it's not at all uncommon for me to get it wrong, and a voiceover bit will sound very obviously dubbed in. Overall, the process I've just described is tedious. It gives me opportunities to walk away and procrastinate, and it's really hard to keep in the flow. All right, Darcy's method is much different. I'm not sure how he gathers his original ideas of how to tell the story, but he writes out an entire written script for the full tutorial video. That sounds like something I can do, right? I'm really comfortable writing scripts. He starts by recording a scratch version of the audio from the script. Then, while listening to that scratch audio, he records the video without talking. After he's gotten the video recorded, he goes back in and he records a good version of the audio to match the video. For my tutorials on touch-retouch and under my roof, I used what I'll call the modified Darcy method, or maybe the Darcy method with a pod feet twist. The touch-retouch tutorial was 90% iOS-based, while the under my roof tutorial was 90% on the Mac. I think the benefits of the Darcy method are more evident in recording on the Mac, and I'll elaborate on why. When I created the under my roof tutorial, I still started by creating a mind map, but I found I didn't flesh it out nearly as much as I normally do. Part of that might be because I know the under my roof tool so well already, I've been using it for years and years and years, but I found out that I wanted to start writing the script very early in the process. I also found that I couldn't stand to wait until I had the entire script written before starting to record. I normally delay recording till the last possible moment because it's so hard to do, so this was a good sign that I was really itching to record. I wanted to practice the new method and recording audio from a script is a very easy lift for me, so I got started really quickly. First benefit, I start recording sooner because the Darcy method is easier. I wrote about 10 minutes worth of script with a reasonable stopping point, and then I used ScreenFlow to record the audio in one cut. I'm not saying I didn't make any mistakes, but it didn't stop and start like I do when recording audio and video at the same time. Since I was only recording audio and the script was on my big display, my mic was on my right side. When I stopped and edited out the few mistakes and did any voiceovers, my mic placement was identical, so it did not sound like a bad dub. In the Allison method, when doing a voiceover, I had to listen to what I had tried to say, memorize it, and then re-record. My skills at memorization aren't great, so I'd clip out the bare minimum, which was often a small segment of a sentence. It was hard to get the intonation to match with the rest of the sentence. Since with the Darcy method I have a script, I could re-record a much longer segment so the cadence and intonation sounds exactly the same. There's our second benefit. Voiceovers sound just like the original, because of the angle and because of the script. Now I'm calling my new method the modified Darcy method because of how he does the audio. I told you he records a scratch version of the audio, then records the video, then records a final version of the audio. I'm not sure how he reads a script for the final audio while actually watching the video at the same time to ensure he says things at the correct time. My method was to do a good audio take, and then record the video. There are some challenges to my process, which might explain why he does two audio takes, but I'll get to those in a moment. When I first started on this new method, I simply read through my script in a normal cadence. But when I went to record the video, I realized I hadn't left myself nearly enough time to execute some of the steps. Now it's not difficult to cut the audio and yet add a pause after the fact, but it does make it hard to record the video when the audio is already moved on. I felt rushed like, oh wait for me, wait for me, I'm still recording video. As I created later segments of the script, I learned to type in intentional pauses, so I remembered to give myself a little bit of time in the appropriate places while recording the video. Now it's hard to actually start recording the video, because you have to ask GreenFlow to do two things at the same time. You have to tell it to play back the audio recording, but also start a video recording session. Now it's up to the task, but the timing of that is tricky. I have to back up the scrubber by a few minutes, hit play, then invoke the video recording, wait for it to let me start, and then sit there and wait until the audio catches up to where I need to be. If I'm having timing trouble, I can stop the audio in ScreenFlow, finish a step and go back to ScreenFlow and restart, but that does add some editing steps. When you flip to ScreenFlow, even though it's on a different screen, the menu bar will change on the main screen, and that just won't do. After I learned to put in pauses, I found I could catch up and doing the steps on the video without too much trouble. Then after recording the video and dropping it in, I could fix any timing problems by putting in freeze frames in the video. Freeze frames are super easy in ScreenFlow. You click in the timeline, grab the scrubber, and just kind of pull the video apart. Then you put the scrubber back at the cut point and hit Command-Shift-F, and that adds a one-second freeze frame. It's really easy to stretch and shrink those to match the audio. If the audio needed a pause to wait for the video, I wouldn't necessarily make dead air while I completed those steps. In ScreenFlow, you can cut a video clip, hold down the Option key, and then stretch or shrink the video to slow it down or speed it up. It's a really great tool to know because it makes your tutorials far less boring. We use it all the time when a step requires typing in text, for example. Nobody wants to watch you painstakingly peck out a sentence, so we speed it up and drop it under the audio where we say what we're doing. So now we've gotten to the first downside. Getting the timing right on reading the script is a little bit tricky. While getting the timing just right on the audio for the script when not recording the video simultaneously is challenging, that downside is far outweighed by how much easier it is to do one thing at a time. As humans, we're convinced that we can multitask, but it's been proven in many, many tests that we aren't actually multitasking. We're rapidly task switching. Even though I repeatedly practice the steps I'm going to demonstrate in a video screencast, it's really hard to remember what I want to say at the same time I'm executing the task. You should see how many takes and retakes I do for the shortest, simplest tasks. It's not uncommon for me to have to edit a segment that ends up only being two minutes long, but it was eight minutes of fumbles either in what I say or what I do on screen. So now we're back to another benefit. Recording only one thing at a time is way easier. Now because recording audio and video at the same time is so difficult, it's stressful and it becomes exhausting. I found that with two separate tasks, I simply enjoyed myself ever so much more. I should add one caveat to this though. Both of the applications on which I tested the new process were very well behaved applications. I didn't run into any glitches or unexpected results. Under my roof in particular is a rock solid application and one I know really well so that definitely helped make creating the tutorial more enjoyable. On the timing of the video and audio recordings with respect to each other, there's one thing I need to work on. JF Press said as my editor for the screencast online videos and he said that my timing was such that I tended to start doing an action in the video slightly before I explained the steps. It's a much more natural thing to have the explanation come slightly in advance before starting to demonstrate a step. JF was able to correct for this, but that's a lot of rework that I can remove if I can get that timing right before sending it to him. I love that JF gives me very gentle suggestions on improvement whenever possible because it helps me improve my craft. The final benefit to the modified Darcy method is that when I'm done, I have a nearly perfect transcript of the entire tutorial. I'm convinced that this transcript could cut costs in creating the subtitles, but I haven't convinced the screencast online team to suggest it to the company they use for transcription. Whether they need it or not, there's a big benefit to me. While there's no substitute for a video tutorial to learn a tool, there's still value in the blog post I do that explains the capability of software Android using. With the transcripts, if I haven't already told you about an application, I now have a nice framework from which to start a blog post. For example, I've done tutorials on Under My Roof and Touch Retouch, as I've mentioned, both of which have a lot of capability and I've never told you about either of them. Actually, Touch Retouch, I told you about a really long time ago, but it does so much more than it used to, and Under My Roof is a grown-up version of a tool called Home Inventory that I did tell you about, but now I could teach you about the new stuff and I've already got a script written that I can use to help work out what I want to tell you. I want to briefly circle back on the Darcy method with iOS. I still like using the Darcy method for iOS, but the benefits aren't as great because it's so much easier to demonstrate things on iOS apps for a video tutorial. The screens are much more predictable, so if I mess up the audio, I just pause a heartbeat and rerecord, and I'll know, for example, that my cursor hasn't moved to the wrong spot on the screen, the menu bar hasn't changed, it's just so much easier to record iOS. I think I'll probably still keep using the Darcy method for iOS, but the benefits just aren't as big. The bottom line is that I'm really enjoying the Darcy method, or the Modified Darcy method, and I plan to keep on using it and refining it until I can call it my own. Are you fatigued by too many subscriptions, but you'd still really like to support the work we do here at the Podfeat Podcast? Did you know that you could go to podfeat.com slash PayPal and just choose an amount that shows the value you get out of the shows? I don't set a goal of making money off the shows, but it does cost money for servers and software and hardware, so every little bit you can contribute will make you a real hero in my books. Whenever Steve and I go on our wild adventures, I found myself learning something new about how to use our technology when away from home. The problems and solutions evolve over time. I wanted to give you a few things we learned on our Antarctica, Argentina, Brazilian trip, some of which are successes and some of which are failures. For many years, I've sung the virtues of Google Five for international data for our cell phones. The model is pretty cool. You get one primary SIM card with voice and data, and up to four or maybe it was five, I forget which, data only cards. You pay a monthly fee of $20, and then it's only $10 per gigabyte up to six gigabytes, and after you hit that limit, you don't pay any more, but you can keep using more data. Because Steve and I could share a plan, we knew we'd never pay more than $80 no matter how much data we used. The other beauty of this plan is that you can turn it on and off at will, so you only pay the $20 per month while you're using it. Now, for a long time, I didn't understand one subtlety of this plan. While it is $20 per month, if your trip extends across two billing cycles, you'll actually pay $40 for the service, bringing the potential cost to $100 for a trip. We found this out when I loaned the cards to Dorothy when she went to Ireland and visited Bart, and she ended up paying $20 more than I had promised her. When we went on vacation with our kids, it worked out to be a pretty good deal because I could pass out all the data cards and pay no more than I would for just one of us. It was a hassle-free way to go because I knew I could stick the cards in and go to pretty much any country in the world and it would work. However, on the Mac Geek app, fairly often, I've heard Dave Hamilton talking about getting a data plan through a site called esimdb.com. I didn't pay much attention to it because I assumed that paying for two cards for Steve and me would be an inefficient way to use data, making the total cost more and a hassle to track. Before we left for Antarctica, I decided to check it out anyway and I am sure glad I did. International data plans have gotten way, way, way cheaper than back when I originally set up Google Fi. Dave recommends esimdb.com because it's a broker for data providers all over the world. You enter either the country or region you're going to visit and you'll see a list of options from different companies vying for your business. They offer different duration plans so you could choose like one day, three days, 15 days, 30 days and within those durations they offer different amounts of data. Let's say you're going to be in Spain for three days, you might only need a gigabyte or maybe 500 megabytes. But if you're going to South America for two weeks, you might want a longer plan with lots of data. At first, I searched for Antarctica and I discovered there is no cell data on the entire continent. That wouldn't end up being a problem because we ended up having satellite internet on the ship but it was still interesting. I was also surprised that satellite coverage existed that far South. We'll get into that a little bit later. On esimdb.com you can also choose a plan with voice service but immediately increase the cost to a level I didn't think was worth it. I knew that my friends and family could use FaceTime Audio in an emergency since they're mostly on iOS. As it turned out, Lindsay was able to call me on Telegram Audio so even if she had been on Android, it would have been possible to talk in voice without paying for a voice plan. The newer iPhones have the capability to use multiple eSims and they have no physical Sims. This paralyzed me at first because I already understood how to sit in a tiny airplane coach seat and change out microscopic digital cards without dropping them. What was this sorcery of an electronic SIM? How could it even work? Well, when you download an app like the one for GigSky, which is the company I ended up choosing for our international data, you tell it the same info you did on the esimdb.com website. You choose the plan and then you put in your credit card information. The other cool part of this is that you can always top up your plan if you run low. I didn't test this but I suspect you need to top up before you actually run out so it's probably a good idea to open the app from time to time. Now for the pricing. Steve and I each paid $14.40 for five gigabytes for 30 days. So we had 10 gigabytes total for 30 days for less than $30. I mean, it was unbelievable. We actually didn't end up needing five gigabytes but how could I turn down less than $30 for the two of us? Had I stuck with Google Fi, it would have been $100 because we did straddle a billing month. So we saved $70 by going to esimdb. Most people we met on the trip just let AT&T or Verizon start charging them for international data. That cost $10 per day. I'm not sure if they were charged while we were in Antarctica but even if they weren't, we were in Argentina for six days so that would have been $60 per person or $120 for the two of us. And again, we paid less than $30. Out of the five gigabytes we each paid for, I ended the trip with 1.8 gigabytes left over and Steve had 3.2 gigabytes left over. So even at $14.40 each, I could have bought an even less expensive data plan. Needless to say, I'm now a big fan of esimdb. Let's talk about photos. Before we left for the trip, Steve and I updated our M1 Max and our iPhones 14 Pro to macOS Ventura and iOS 16 respectively. We turned on the new shared photo library feature and we ran some tests so we were sure we understood how it worked. We wanted to have a shared photo library so that every picture either of us took on the trip would be on all of our devices. In the camera app, you can enable the shared library so that every photo you take goes into it until you disable the shared library button. Our plan was to keep our photos separate until we go on a trip where we're likely to want each other's photos. When we got home, we simply open the camera app, tap the shared library icon to toggle it off. I have to say that having a shared library on this trip was positively liberating for me. Steve and I have a habit of taking the exact same photos of the exact same thing because we don't want to have to ask the other person to send them to us. On this trip, I actually took far fewer photos with my iPhone because I could see Steve capturing what we were seeing. That allowed me to be more in the moment enjoying things that I normally am. I did take artistic photos or I worked with panoramas to try to capture the grandeur of the waterfalls and I was able to use my big girl camera to get some fantastic close-up photos of the penguins. Together, we got complimentary photos instead of duplicates. Since we had good data connectivity in Argentina, our photos happily zoomed up to the cloud and backed each other's copy of the shared library. It was awesome. Now every night, I put my memory card from my big girl camera into my Mac, pulled the photos into our shared library. While in Argentina, the photos happily went up to the cloud and back down to our phones in the shared library. But there was one huge problem. Remember I told you that Steve and I upgraded and enabled the shared library on our M1 Macs? Well, Steve decided before we left that it would be prudent to not bring his M1 Mac, but instead to bring his 2016 Intel MacBook Pro on the trip instead, just in case something happened to his backpack. This strategy saved him a few years ago when we went to Peru and his backpack was stolen. He was very glad that he'd been smart enough to carry his old laptop instead of his new one. Now the problem with this strategy for this particular trip was that the 2016 MacBook Pro cannot be upgraded to macOS Ventura. Neither of us remembered that this would become a problem. The MacBook Pro on macOS Monterey received none of the photos we were taking because they were all in the shared library and it didn't know anything about shared libraries. He was so bummed. That meant that in order to use his Mac to write posts to friends and family, he had to connect his iPhone to his Mac using a lightning cable like an animal and import them images manually. As it turned out, once we got on the ship, that was the only way either of us could do it because the internet was so slow. I ran a ping test and the latency was comically bad from Antarctica. In the terminal, if you type ping www.apple.com, it will show you how long the data packets to take to go from your computer to Apple servers and back. You could use any website, but Apple's are really fast, so it's a good one to use. From my house, this is normally, I don't know, 5, 10, 15 as much as 20 milliseconds to get to Apple, but it was taking more on the order of a full second over satellite internet on the ship. Not only that, it was dropping around three out of 10 packets that it sent. To be fair, though, it was extraordinary that we were able to even get this satellite service being so far south from the equator. You see, geosynchronous satellites sit at the equator, but they have a wobble to their path and they call that inclination. This makes a path look like a wave going above and below the equator over the course of 24 hours. Most geosynchronous satellites have a very small inclination, like a half a degree, but that inclination isn't big enough to be able to see around the curvature of the Earth to Antarctica. To hit the South Pole, for example, only a few geosynchronous satellites have an inclination big enough, 8.7 degrees, and at that, it's only for four hours per day that that inclination allows it to be far enough down to be seen at the South Pole. Now, we were at around 65 degrees south of the equator on the ship, so we had access for much of the day. I put a link in the show notes to usap.gov where you can read more if you're interested. Now, rather than complain about one second ping times, we were delighted to have even this tiny pipe to get our messages back home, but it did hamper our whole photo strategy. I did the same dance as Steve, importing my photos manually from my iPhone to my Mac on the ship. I also used my big girl camera to get super cool close-ups of penguins, as I mentioned before, and I imported them to my Mac as well. Now, I never figured out a batch method to move the big girl method, the big girl photos from my Mac back to my iPhone so I could show them off to other folks on the ship. I did airdrop a few of the best of the best, but it seems that there should have been a way to push the photos the other way. I met a woman on the ship who had a better strategy that I will be deploying in the future. She bought one of those SD card adapters with a lightning connector for less than 20 bucks. She connects the SD card adapter to her iPhone, puts in her big girl camera's SD card, and then the iPhone recognizes it in Apple Photos and offers to import all new photos. If I'd done that, I could have then connected the iPhone to my Mac and pulled both the iPhone and big girl camera images into my Mac and back them up from there. Now, while I tried to be very rigorous with my process, I knew that manually importing photos while the shared library was still active would assuredly cause duplicates. I don't have my final count, but I've been cleaning up my photos since I've been home, and there's at least 500 duplicates because of that process. Oh, I'd rather have duplicates than missing photos. Now, speaking of backups, when Steve and I traveled to Ecuador and Peru a few years ago, we employed a good backup strategy that saved us when Steve's backpack got stolen. We carried two external SSDs and we daily backed up our photos from our phones, Steve's camcorder, and his GoPro and my big girl camera. But the smartest thing we did was we swapped backup drives. So I was carrying his and he was carrying mine. In the airport in Cusco, Peru, when Steve's backpack was stolen, he lost not only his laptop, but also his camcorder, his GoPro, and by the way his passport, but that's a whole other story. While that was a very, very sad day, imagine if we hadn't swapped backup drives. All of his photos of the Galapagos and Machu Picchu would have been gone. Needless to say, we did the same thing on this trip. If you learn anything from this tech and travel post, consider following our lead and carrying backup drives and swap them with one of your fellow travelers whenever you're moving around. Now, the ship we were on was pretty small, only 150 passengers. That meant that after a few days, it was pretty easy to have collected quite a few new friends. When we'd get back from our excursions, we'd always talk about what we'd seen, and invariably someone would say they'd gotten a great photo of someone else on the excursion. Immediately, the words you would hear would be, air drop it to me. All day, every day, they would be happily swapping photos around, and it was amazing how well and how often it worked. The sad part was that the Android people just kind of sat there lonely and left out. I wonder how many people go through an experience like that and maybe switched iOS as a result. I actually felt sorry for them. Now, Apple recently changed the settings for AirDrop, which was something I needed to teach people on the trip. In order to receive something via AirDrop from someone you've just met, you need to set it to accept from everyone. Now, if you're up to date on iOS, you can't leave it set to everyone anymore. You can only change it to everyone for 10 minutes. Leaving everyone open was a surefire way to get photos, you may not want to receive, so I think it was a good change. But this also gave me an excuse to lecture my fellow passengers on keeping their phones up to date. If I was helping them, and in the AirDrop settings, it said everyone, instead of everyone for 10 minutes, I knew they had not kept their phone up to date. I'd point to the giant red number on their settings app and tell them that task number one, when they got home, was to run that update. Now, I thought I was quite clever to show them how to simply search for AirDrop within settings. Instead of trying to remember where Apple had buried it in settings. But on the very last day of the trip, when we were in Iguazu Falls, one of the tour guides offered to send a cool compilation photo of the falls in normal times, a drought year, and a flood year. He said that he would AirDrop into all of us, again, leaving out our Android brethren. He then explained a much easier way to change AirDrop settings that I didn't know about. Pull down in the upper right to reveal Control Center. Press and hold on the airplane mode icon in the upper left box that has all of the network connections options, like Wi-Fi and Bluetooth. One of the options on that page that comes up will be AirDrop, where you can select between no one, contacts, and everyone for 10 minutes. I was so excited to learn this new trick on how to change AirDrop settings, I had to share it with you. By the way, you don't have to click on the airplane itself. You can click on pretty much any one of those buttons in that area. But I find that the other ones tend to get toggled off, but for some reason, airplane mode doesn't. So that's why I choose to push on the airplane. Now on the ship, I realized that my Mac was trying desperately to sync photos to iCloud, which was A, never going to work on that internet service, and B, it was jamming up the itty-bitty internets for us and everyone else on the ship. I had to take the drastic step of shutting off iCloud. Now, if you've been listening to me for any length of time, you know that turning off iCloud is asking for pain and suffering when you have close to 100,000 photos. When I got home, my Mac checked all 94,322 photos one by one until it was sure they were all synced properly. Now it used to take like three or four weeks to do it, but this time it was only three days, something they've done it's doing a lot faster now. But during that three days, my Mac's library didn't receive any new photos and the worst part was it gave me zero feedback. It was annoying, but I suffered through it. And when I shut off iCloud, I knew what I was doing, getting myself into this agony with the photos, but I forgot what else would happen. When I got back home and I went to save some files to my new Silicast folders, I noticed that all of my documents were gone. I eventually discovered the archived copy it had automatically created, but it wasn't until I turned iCloud back on that the real iCloud folder came back. It's a bit scary there for a moment and I had to remember to delete that archive copy when I turned iCloud drive back on. I also learned how much I depend on using the continuity features of iOS with macOS. For example, I sometimes need to type something into my phone, but I'll just type it on my Mac or my iPad that has a keyboard and then I'll copy it and tap on my phone and hit paste. I logged out of iCloud and I lost all continuity features too. It made me appreciate even more the convenience you get when you go all in on Apple. And one of the big weirdnesses on the trip was messaging. While my beloved Telegram worked flawlessly for sending images to groups of people of iOS and Android persuasion alike, the Messages app had lots of problems. I knew I wouldn't have my real phone number since I was using an eSIM from another provider, so I made sure that the Messages app was set to send and receive from two of my email addresses. But here's the weirdnesses. First of all, I could send a text-only message to anyone on iOS. That worked. But I couldn't send a message with an included photo to anyone on iOS. I also couldn't send a text-only message to a group of people who were on iOS, so I couldn't send them one person. I could only write text to one person. And I couldn't send any kind of message of any type to even a single person on Android. If anyone knows why that happened, I'm all ears. I've never seen that before. Now in my beloved Telegram, I noticed something nifty. While on the ship, if I uploaded an image to someone on Telegram, as you would expect, it would be super slow and take forever to put the image in. But if I uploaded that exact same image to a second person or to a group in Telegram, it would be super fast. I knew they stored your data in the cloud, but it appears that they can recognize the same content and they simply don't upload it a second time. Now other folks on the ship were using WhatsApp to communicate with friends and family at home, and it worked equally well for them. WhatsApp is owned by Meta, and I've sworn off all services from Meta, including Facebook and Instagram. Now I never liked the interface on WhatsApp anyway, and I only knew three people who used it, and I convinced them to move over to Telegram, so it wasn't a big loss for me. Now over the years, I've always traveled with my laptop and my 12.9 inch iPad Pro. The Mac is essential because I write an email travel log every day telling folks about our adventures. I've tried doing it on the iPad, and it takes me about five times as long, especially trying to embed photos into these letters. It's very hard to carve out the time on these trips to write this document as it is, so anything that makes it take longer is a non-starter. So that's why I carry my Mac. Now I've always had huge laptops with a 15 inch for six years, and then for two years with a 16 inch. So I bring the iPad along for everything but writing the travel log. I do use the iPad Pro to watch movies on the plane, for example, because the battery life is so amazing. On our trips to Iceland and the Eclipse trip in Chile, there was a lot of time on buses. Even though the final email had to be written on the Mac, I often brought the iPad along to work on a rough draft without photos, and it was a big help to get that done during that dead time while we were stuck on buses. But now I have a 14 inch MacBook Pro with also amazing battery life. I found I didn't find myself reaching for the iPad at all. The 14 inch doesn't weigh that much more than the 12.9 inch iPad with a magic keyboard. I did watch a movie on it on the way there, but I could just as easily have watched it on my Mac. For the next big trip we take, I very well might not take my iPad Pro. Carrying both is really heavy, so my back would thank me. And last June I told you about a magnetic wallet I got from King Guard, along with a case I bought from them. All together, total cost 20 bucks. This magnetic wallet holds just two cards and it sticks to the iPhone's MagSafe connector. I kept it connected to my phone for a couple of weeks when I first got it, but over time I stopped using it regularly since I carry a purse. But you know what? On the ship it was the perfect accessory, held my magnetic key card for a cabin, along with my phone when I tuteled off to eat or drink. You can't leave the cruise ship without scanning your rim key and you have to scan in when you get back on so they know they didn't leave you with the penguins. Having the magnetic wallet for my key card was ideal and I will be bringing it with me on every trip from now on. And one of the fun things about this trip was that I got to do tech support for my new friends. On the very first day of our trip with the alumni group, while we were still in Buenos Aires at a hotel, a woman named Linda walked up to our table and she said, Do you have an Apple watch? When we said yes, she plopped down at our table and said, Why does my phone know the new time in Buenos Aires? But my watch is stuck on the time in New Jersey. That was a great question, Linda. We tried several easy things while chatting with her, including restarting the watch, but we were unable to fix it. We ran out of time at breakfast, but the next day we were waiting for our lunch at the hotel restaurant and Steve saw Linda out in the lobby. He dragged her over to our table so we could work on it some more. She turned out to be hilariously entertaining so it was really fun to work on this for her. I'd like to take full credit for figuring it out, but this one was definitely a team effort between Steve and me. It turned out that Linda's phone wasn't paired with her watch. The reason Linda didn't notice sooner that her watch was impaired was because it was a cellular Apple watch. While at home, it was happily using its own connection to receive email and text notifications and do all of the other things an Apple watch can do. But as soon as she left the US, her cellular connection was gone so the watch stopped getting any kind of updates including accessing the time servers. Now, Linda had given us a clue. She told us early on that she'd recently gotten a new phone. Evidently in the transaction with Apple, no one told her she'd need to pair the watch with a new phone.  She happily agreed to let us do that. After running the pairing process, it offered to download her watch configuration from an iCloud backup. Once we did that, she was 100% in business. At this point, we basically became legends in our tech support skills. Okay, maybe not legends, but we're definitely spread that we knew what we were doing. Our new friend Carol simply could not get internet while on the ship. She was very disinclined to bother me.  I love doing this. And whenever I'd suggest we work on it, she often didn't have her phone with her. Can't blame her. She couldn't do anything with it. So I wasn't able to help her over and over and over again. We kept making connections and I wasn't able to help her. She was also very skilled at throwing in information to obfuscate the root cause. Unlike Linda, who'd given us a very good clue, she said things like, well, it all started when they made me install a two-factor authentication app. I didn't understand what that had to do with this. Anyway, finally, on the last day on the ship, I got her to bring her phone to me. In order to connect to the ship's internet, at least once per day, you had to navigate to wifi.ponent.com and enter a username and password that we were issued on the first day. They gave Steven me two login, so of course I had to go back and get three more because we had a lot of devices with us. I asked Carol if she'd gone to that webpage on the day I was diagnosing the problem and she said, no, what are you talking about? I've never been to that page. I don't know what you're talking about. What is this username and password login nonsense? So we toddled over to the front desk. I arm wrestled the recalcitrant woman behind the counter to give Carol a login. She said, well, she got one when she came in and I said, no, she doesn't have one. She said, give it to her. Anyway, I entered the credentials and Carol was connected. She was beside her with self with awe at my incredible technical skills and was happy to finally have internet on the very last day of the cruise. I sure wish I'd been able to fix it for her sooner. Now I'm going to change the name of the third person I helped because her situation revealed so many frightening security issues. We're going to call her Martha. No offense to the lovely Marthas out there. I just picked the name out of a bag. So Martha could not get into email on the ship and she couldn't send text messages but she could browse the web. Since this was clearly not a connectivity problem, I was baffled at what could be the root cause. When we got back to Buenos Aires, she still couldn't send messages or receive email. She eventually mentioned that she'd gotten some emails from Google about some security alert but she'd ignored them. I reviewed the messages and then I looked at in her settings on her iPhone and there was a red alert on her account name in settings. I dove in and it was telling her that she needed to re-authenticate to her Google account. I asked her if she knew her Google login and she proudly pulled out a piece of paper from her purse with all of her important usernames and logins on it. I was suitably horrified. I was even more horrified when I scanned the list of passwords and I saw the same pattern of four numbers in every single one of her passwords.  Yep, the same four digits. Now, even though she said she didn't have any important passwords on that piece of paper, remember that password resets go to your email. So if someone had stolen her purse, she'd lost her phone, lost her email password and it wouldn't take a rocket scientist to guess her four digit passcode to get into her phone to access said email. She would have been owned in every sense of the word. We had a short chat about one password and I told her that when she gets home, I'm going to help her get started. She's not ready quite yet, but I'm not going to stop badgering her until I get her started with one password. Once I found the right password or email on her little scrap of paper, I entered it in his settings in her iPhone and immediately all of her emails came flowing in. Back in 2019, I interviewed Eric Matheson from Omnicharge about their full range of power banks. Shortly after that, I bought one of their USB-C power delivery banks and it is one of the most useful devices I travel with. It sports 20,000 milliamp hours of capacity and has two USB-C ports with power delivery and two USB-A ports. Now the newer model they have supports 100 watt charging, which means they can quickly charge a MacBook Pro. My four year old model is only 65 watts, but it can still charge my laptop just a little bit more slowly. With modern Macs, having a spare battery around isn't as important, but for travel with a bunch of peripherals, it's super handy and I'll explain why. Steve and I made a rule years ago that when we check into a hotel or a ship or stay at someone's house, we will always keep the same side of the bed as we do at home. Now we made this rule not because we would feel weird swapping sides, but rather so we wouldn't fight over who got the best side that had the bedside table and reachable outlets. When we arrived on the ship, Steve realized that while his side had a table, there were zero outlets. I graciously loaned him my omnicharge power bank. That gave him four outlets for his devices. Now this was way overkill for his phone and his watch, but allowed to have them buy his bedside where he wanted them at night and then during the day, he moved the power bank to the counter in the room to recharge it. He was delighted with his solution. The other reason it was super useful on this trip was because the ship had European outlets when we assumed it was going to have Argentinian outlets.  Using the omnicharge, he could charge his device at night using no power outlet and no adapters at all. During the day while we were out and about, he could take up one of those precious adapters to charge the battery. Now note that this device can also be plugged in to charge with one USB-C port while using the other USB port to charge a laptop and you can be using the two USB-A ports to charge a phone and a watch. It can even do data transfer via USB to your laptop to your phone. We didn't need to do it, but it's a good thing to know that you can. Now I'm toying with the idea of buying myself the new Omni 20C Plus for 250 bucks and giving Steve my old one so he would always have power when he needs it and I wouldn't have to share. Now the funniest tech and travel story of the trip actually happened to our new friends, Bob and Nancy Ellen. Part of our trip was to Iguazu Falls which is an amazing place. It's the second largest set of waterfalls in the world right behind Victoria Falls. There are 275 falls spanning 1.75 miles. As we rode to the hotel, our guide told us that they have capuchin monkeys in the area. She explained that these little monkeys are very clever and know how to open the sliding glass doors to the balconies of the hotel rooms. So be sure to lock your doors. When we checked into the hotel, the person behind the counter repeated the exact same thing. After our hike, we all went down to the massive infinity pool. I'm serious, this thing was giant. It was 50 meters by 25 meters. Anyway, we went down there to have a nice little swim after our hot hike. We were hanging out with Nancy Ellen and Bob when someone said, Hey look, there's monkeys on one of the balconies. We were all enjoying the spectacle when Nancy Ellen said, Bob, is that our balcony? Followed by, I'm not sure I locked the door when I came in from admiring the view. Well, Bob scampered up to the room only to find their mini bar completely rated and monkeys all over the balcony eating Reese's peanut butter cups and other treats. While you might be enjoying this story at Bob and Nancy Ellen's expense, you might also be wondering what the tech angle is to this story. Well, on top of the Reese's and other treats, one of the monkeys stole the spare battery for Bob's Canon DSLR camera. At first, the monkey dropped it and then wandered off when they couldn't figure out how to eat it, but they came back later and took it to parts unknown. You know what? The joke's on the monkey though. It wasn't a genuine Canon battery. It was a cheap knockoff from Amazon. If you comb the archives of podfeed.com, you'll find that as far back as 2006, I started trolling the audience to try to get someone to listen to the nocella cast from Antarctica. Back then, I used to regularly review the list of countries from which someone had accessed the site and I had 93 countries by then, but no one had ever come from Antarctica. I know Antarctica is in a country, Tom. Just stay with me here. Anyway, in 2008, someone named Michael wrote in a comment that he was planning a trip to Antarctica and he said he was going to make sure to get a photo of him with his iPod and the show art from the continent. But to my memory, I never even heard from him after the trip. And you know the old adage, if you want to have something done right, sometimes you just have to do it yourself. I've included a photo in the show notes of me wearing my podfeed shirt, holding up my iPhone, playing the nocella cast on the ship with the coast of Antarctica in the background. The bottom line is that on every big trip, I learned new things about how to use our tech on vacation that we take for granted when at home. I learned not to leave the camera batteries out with monkeys around. We learned not to bring it all back on trips. I debated whether to bring my big girl camera along to Antarctica, but even with all the faffing about with importing photos, I got some absolutely terrific photos of penguins that I would have never gotten without it. While the iPad Pro probably won't take the next trip with us, I think I'll still carry my big girl camera. I hope you enjoyed learning about what worked and what didn't on our grand adventure to Antarctica. All right, that's going to wind us up for this week.

This is stock number 11092A. We are here at Summit Automotive in Fond du Lac, Wisconsin. You're new and used like-duty truck headquarters. Today we are checking out this Super Clean 2016 Chevy Silverado Double Cab 6.5 foot short box. This truck has the 5.3 liter V8 motor. It has been fully safety and inspected by our service shop as a fresh oil and filter change. All the fluids have been checked and topped off. And this truck is 100% ready to go. Summit White is the color. We shoot all of our videos in 1080p, 60 frames per second. So if you have HD capabilities on your computer, tablet, or smartphone device, turn them on right now because it is definitely the best way to check out the quality and condition of the truck before seeing it in person. This one has the HID headlamps, the LED running lights. And if you'd like to check out all the photos on this truck in the upper right hand part of your screen is a link to our website. Click that and check us out there. This one comes with the 20 inch factory alloy rims with the chrome covers. No scuffs or scrapes on that rim. It does have Falcon, Wild Peak, AT tires. These are 275, 55R20s and they have probably about, I'd say, 50 to 60% of the tread left on them. Front fender is in excellent shape. I didn't see any dents or dings on there. Headlight lenses are nice and clear. And like I said, this one does have the HID headlamps and the LED running lights. And it is a custom package, so more of the entry level, but you do get the nice headlamps and running lights with this truck. The roof, I'm sorry, the hood on this truck is in really nice shape. Didn't see any major dents or dings on there. And the passenger side fender is in nice condition as well. The only thing I really noticed on this truck is this chrome cover does have just a little bit of peeling going on it. But other than that, the rest of the truck is in really nice shape. And as you go down this side of the truck, take note of how clean the body is, how reflective and mirror-like that paint is. We take these HD videos, so if you are far away, or even if you're close by and just can't make the trip down, you can still see the truck here, the truck, and have confidence in the vehicle that you're looking at, because we realize that these are used trucks and they're not all going to be perfect. And that's why we do the videos so that you can get the most accurate representation possible. And that's also why we offer the Summit Auto Fastpass option in the upper right-hand part of your screen. A link right to our website where you can apply for financing, get pre-approved, see a payment quote, even appraise a trade all from the comfort of your own home. So when you do get here, all you have to do is drive the truck, love it, and you'll be all set to go. Back tires have just as much tires as the front tires. And you can see the frame and underbody is in pretty nice shape. Those box rails have absolutely no corrosion, and that's where you always want to look on the underneath of a truck for corrosion. So those box rails, because that's what will be the most... It'll be the thing that goes first. Lower rockers other than a little bit of dust on there look pretty good. Didn't see any corrosion on them. And as we go down the rest of the side of the truck looks really good box. I didn't see any dents or dings. You get the rear bumper steps. No dents or dings on that rear bumper. And it does have a full towing package, which includes a receiver hitch four pin and seven pin wiring. The tailgate is in really nice shape as well. And it does have a locking tailgate. This one also has the LED bed lighting, which those lights right up there. They light up with the cargo lamps. And it does come with a factory Chevy drop-in bed liner. Tailgate shuts nice and solidly.  And for full disclosure, this back room is in excellent shape as well. Down the rest of the side of the truck looks really good. Inside the custom package gives you the gray cloth interior. There are no rips or tears on the seats. They are in really nice shape. Comes with factory all-weather floor mats. Carpeting is in nice condition as well. Auto headlamps. And you do get the factory brake controller. Tilt steering wheel, power windows, power locks, and power mirrors. And as we hop inside the truck here, turn the ignition on so you can see the miles and everything. This one has 77,656 miles. You do get that digital speedometer. Instrument cluster is very nice and clean. You get cruise controls on the left. Steering wheel is in nice shape. Didn't see any major scuffs or scrapes on that. And you do get a six-speed automatic transmission with the optional tap shift. This one does have AM FM radio. And it does have Bluetooth capabilities.

Hi, I'm Zor. Welcome to Unisor education. I would like to start a new chapter called statics and in particular we will talk about equilibrium today. Now this lecture is part of the course called Physics for Teens and it's presented on Unisor.com website. It's a free course. No financial strings are attached, no advertisement. So I do suggest you to go to this website for this lecture and all others because all the lectures are arranged in logical sequence because sometimes you can find it just by accident on YouTube but anyway just I have to tell you that this is part of the course. So take the course. And by the way there is a prerequisite course for this which is called Mass for Teens and it's also on the same website. In particular it's very important to have a very good knowledge of vectors and calculus to really be comfortable in the course of physics. So if you are not that comfortable I do suggest you to take the Mass for Teens course first and then go to the physics. Alright so let's talk about equilibrium. Statics is I would say more ancient kind of mechanics than dynamics. Dynamics is all about motion. Statics is about bridges, buildings, about different aspects of life of the people even before they started thinking about what exactly kind of forces are involved in in our everyday life and what kind of quantitative measure of their movements that we can introduce. So all these Newton's laws etc. they are all subsequent to this. In the beginning people had to build buildings and that's probably one of the most important stimulus to think about statics. And obviously in particular they were concerned about equilibrium. So what is equilibrium? Well equilibrium is a state of all the forces combined together which result in no movement basically. So if you have let's say one particular object let's talk about point object and you have many different forces applied to this. If as a result of this the object does not move we are saying that the forces are balancing each other and altogether this is a state of equilibrium basically state of rest so to speak. Now an example for instance if I'm standing right now on the floor within the frame reference associated with earth let's say I'm not really moving anywhere right so I'm standing still and why because I have two major forces applied to my body which is my weight which goes down and the reaction of the floor which basically goes back up and these two forces are equal in magnitude and opposite in direction which means they balance each other. So obviously we all understand that the forces are vectors because they have magnitude and direction and the combined action of all the forces obeys to the laws of vector algebra. So if every vector is associated with every force is associated with a vector and these vectors of all the forces applied to one particular object sum together giving the null vector that is the condition of equilibrium. Now another condition of example of equilibrium is actually the building for instance the building stands now what kind of forces are acting on each brick for instance well there is a pressure from above there is its own its own weight and there is again a reaction from the from the bricks underneath. If you have a bridge for instance and there is some weight on the top of the bridge a car let's say again the car presses down to the bridge with its weight but the bridge has certain elasticity because it's probably built of steel. Steel has certain elasticity and it actually supports the car and it doesn't fall down. So again the car standing on the bridge is at equilibrium. All right so we will basically learn about equilibrium by considering certain examples and that's exactly what I would like to do. So example number one is you have the following construction. So this is the weight of this particular point object and it's hanging on two threads. Now this thread, thread A is horizontal now the thread B is at angle phi. So this is some kind of a knot which ties together all these threads. The thread which leads to the weight the thread to which leads to one support one wall or whatever and another one. Now my question is what kind of tensions of these two threads actually can be observed based on the weight of this particular object. So there is a tension which goes this way and the tension which goes this way. This is TA, this is TB and the combination of three vectors this one, this one and this one should give me a zero vector, null vector and that's the condition of equilibrium. So now this point is not moving. In this and many other cases we actually can do this not moving condition we can express it in different ways as equations, equality of the forces. So what I'm going to do is first I'm going to project all my forces to a horizontal line. Now this force on the horizontal line has no projection because it's perpendicular, right? So the weight doesn't really contribute to movements left or right. Now the force TA therefore must be balanced by projection of TB on the horizontal line. TA is already completely horizontal, right? So TA is the magnitude of the vector which goes to the left, magnitude. TA is not in this case, now if I will put the line on the top that would be a vector but this is just the magnitude of the vector. So magnitude of this vector should be able to the magnitude of projection of the TB and the projection of TB is TB times cosine of phi. So this is a result of this particular point not moving horizontally. It's also not moving vertically. So what are projections of all my vectors onto the vertical line? Now this is 0 so TA does not contribute to any vertical movement since it's a horizontal vector. Now this is definitely down and this is up and the up would be now this is also phi so this is TB times sine of phi is equal to W. Again W in this case is not a vector it's a magnitude of the vector. This is a vector. Now these are two equations with two unknowns TB and TA which I can find and knowing the magnitude of these vectors and knowing their direction basically I have solved the problem right? Alright so how can I solve? Obviously I can find TB from here TB is equal to W divided by sine of phi and now I can find TA which is TB times cosine which is W cosine divided by sine phi or if you wish cotangents of phi. So this is now the problem is solved. Now let's consider another problem. So I would like to use these examples to basically illustrate what the equilibrium is and how conditions of equilibrium can be basically calculated. Now in this case I have an inclined plane with big object here with the thread goes around the pulley down and the smaller object here and I know that masses I know masses but I have to find out is what is the angle when these are balance each other. So this is a state of equilibrium. This is given to me. Masses are given. Question is what's the angle? Okay now let's just do exactly the same thing as before. Now this force is always going down and this is mg. Now this force also down this is capital MG but in this case it's very convenient to break it into two components. One component goes down perpendicularly to the plane and it's very important because there is a reaction of the plane which is equal to in magnitude. Let me just make it really equal. Something like this. So this is mg times sine phi right? This is phi and this is phi. Now and this one no this is cosine I'm sorry this is mg cosine phi and this is mg sine phi. So the mg cosine phi is completely balanced by reaction of the force and this force which is mg sine phi. Since we are in balance in equilibrium is completely balanced by tension. So mg sine phi is equal to tension. On the same hand the tension is balancing this force. It's the same tension. This is the same thread the same tension. Obviously assumed that there are no friction etc and this is ideal. All ideal conditions obviously. From which we can very easily find sine phi is equal to m over capital M and phi is equal to arc sine m over capital M. That's it. We found the angle where everything is in balance. If this angle will be greater then the bigger mass would just pull to the left. If the angle is smaller there is no friction right? Now this smaller mass would go down and if we are in equilibrium this is the condition of equilibrium. So basically these are a couple of very simple examples of the state of equilibrium. A state of rest when all the forces acting onto the same object are nullifying each other. So basically if you have a bunch of forces of i where i is one two etc and so you have n forces applied to the same point object. So talking about point object and all the forces it's at rest if sum of all these vectors is equal to null vector. So that's the condition of equilibrium and these are a couple of examples which kind of illustrate it. Okay that's it. I would suggest you to read the notes for this lecture. Every lecture for this and every other course which is on the Unisor.com. It has notes. It also has exams. So I do suggest you to go through the website to have a complete course at your disposal. That's it. Thank you very much and good luck.


Good morning sub traders welcome back good to see you on this lovely Thursday how's everybody doing good to see you good morning Grant good to see you Sam well I'm gone everybody here who everybody can hear me loud and clear good all right well listen couple exciting things moving on this morning look good little pops going on this one thing let me tell you just gonna see the roots that was an unbelievable stock it had some I guess has some great earnings yesterday you could see the stock was five dollars let me just blow this up so you guys can see a little bigger stock had a really nice move I mean went from almost six pop away to about 13 damn that's some big move over there the only thing that freaked me out this morning was this pop right here around like 740 we had I know a lot of you guys are jumping into it and trading it because you know we start trading here about 745 stock literally ran from 1320 all the way up to about 15 and then this little slingshot here was absolutely gross I mean that thing was pretty scary it is a very very volatile stock and you know what when I was looking over here on level four looks like there's a lot of how could I say it probably just could probably say a little bit different than me but it seems like a lot of like people testing it I'll show you what I'm talking about so I back in the old days will call them flash orders and a flash order just in order to put all these orders out there and then pull it cancel it pull it you see all these orders right here these are flash orders you know they put an order out there they cancel it they change your mind that means could be a lot of algorithm stuff like that I know Josh is having class today with at Cybertry University you know please hopefully everybody enjoyed yesterday's classes but a lot I think has to do you know these are the things you have to learn and understand so you won't get caught up on that because you want to be on the wrong side of stock like this but but but there are a couple of stocks moving will keep a close eye on them and you know I got a couple other ones want to go out there and share Dario good to see you all welcome very much on YouTube and everyone else alright so let's go talk about what happened yesterday now yesterday honestly I didn't really think it was the greatest day but we did have some really nice movers I want to start off with put this on a two day chart right here so I thought the ucar was fabulous I mean this thing started right around here right around this 560 and what time was that she was a little bit of a laycomer and you know we were sitting there trading in the trading room and you know we post those things out there all of a sudden stock literally went from like 585 and right around 10 o'clock and then I had this little shake right here and move right here around 1006 I think that's where everybody started getting into a little bit and that was the nice move from that 635 all the way up to a beautiful 920 and you're talking about within 30 minutes and had this little slingshot right here and kind of kind of flattened out got kind of ugly after a little while but she wasn't that bad when we first found it which started moving right around these time these prices right around that $6 price range really nice mover nice stock a lot of you did pretty well this one also a lot of you remember we trade this a couple of days ago early in the month I look here in the long term chart right here you could see that the stock basically ran from 60 cents to $3 it was unbelievable that day well she had a good move yesterday but then you know listen I think we saw the writing on the wall we knew this was going to be you know a typical shake you know a little short squeeze right here ran from 160 all the way to about 260 came right back down it got halted so many times and you know the big thing for everybody was in the cyber room we mentioned a couple of times we said guys don't get caught up on the stock don't look at what happened a couple of days ago I think it's going to happen to get there you know there's a lot of day traders are probably jumping into it just take the money and run it did exactly what we thought it was going to do ocean was also it's pretty funny at you know ahi ocean sounds like next next next stock should probably be tuna but this stock also was probably was the best stock in pre-market yesterday I mean this was basically it but once the market opened up she wasn't so friendly she came all the way back down to 680 but this is where a lot of you hear that we hear yesterday here in the morning meeting you could see that this stock went from 570 all the way up until about 9 o'clock rent about $8 a share and you know even if you showed up late this was great yesterday actually if you're watching this video you could always go back and you can always go back and you can watch yesterday's recording on our YouTube channel but right here everyone saw the stock go from that $7 name nice popped about eight that's not bad a dollar move I mean that was a pretty pretty nice pop right there and also last but not least Carvana was good in the afternoon stock had a good move now Carvana you could see it right here you know it's funny I was watching you know obviously just for some of you know know this Carvana was $350 stock I mean you look at it where it's now and you saw the run that I had you'd be like wow that's a hell of a run this thing has a long way to go but anyway I was watching TV they're starting to advertise and doing everything so I don't know maybe maybe they got some funding I know they had good earnings and they did they beat earnings so Carvana looks like it's probably make a little bit of comeback but just be very be very careful of Carvana because it's not the easiest stock to trade like it used to okay so that's the point I want to keep an eye and one of the stock I want to throw in the mix you know I'm a big fan of boil okay now boil right here just want to bring this up boil also was $120 stock the stock got decimated got destroyed well she's been on a pretty decent move you know she's got this little resistance levels right around here around this 320 she's been coming back let me show you here on the long term chart you could see she's been on like a little bit of a trend this is not a day trade okay this has to be a swing trade and it's got to get past this just on the $4 price price range but you could trade several thousand shares of the stock you know just I would probably I'm going to probably I still own it and I own it I'm kind of like flat right now but I'm averaging up if it continues to go higher so you know as a swing trade you know because boil got so crushed everything else I would keep a close eye on it now what's moving in this morning let's go over a couple of stocks that's that which came up on the watch list now there's this one right here it's up about 145% LC FY it started on $8 ran all the way to $20 now that is all pre-market now this is the issue with the stock it is extremely volatile some of you are probably getting some alerts seeing people talking about it on their watch list this is probably already a category 5 okay and you know if you're in class and you win the class of Josh yesterday and he's talking about charts and everything else part of that category of classes that we teach is you know the big thing we teach is called the three T's tradable trend and trap well the stock is not tradable you can't get in out of it you can really blow up your account you got to be an advanced trader to trade it I know it sounds beautiful see a stock over 8 to 20 but it can go from 20 back down to 8 and you can blow up your account so if you're an advanced trader it's going on my watch list but you got to be one of those traders that make you know six figures a higher to trade it you know to make to kind of be up your alley now if you still feel tempted you want to do it just don't go out there and trade a lot of it maybe trade you know 50 shares 100 shares you know I mean so if it moves a dollar you can make 100 bucks 100 shares so that's where you got to look at us mentally could the stock make a big move well listen even even a small stock like that you got to be a little concerned so next stock that also made the watch list right here is the stock right here is PIXY now we trade the stock in the past the stock you could see it got really beat up right here PIXY actually had a nice move you know you can see here early in the morning now what I like about the stock right here is this so there are some buyers right here that just showed up that are holding up here around 260 but if you notice the buyers are pulling their orders okay so that really makes people skeptical I don't know if I'm really that much of a buyer as much like I said it's got some support levels it's holding here since about 530 this morning so you know what it's not a bad looking stock it's inexpensive it's got a very good spread it's very trade so that one we'll put it on our watch list roots is already on the watch list we already talked about that one just once again very volatile big big swings a lot of flash orders in it I know some people logging in late right now whatever it is just be very very careful when it comes to that now a couple of the stocks out there I want to bring up Brian says the in the cybergroup room the AGLE yeah so AGLE is got a huge runner up the only issue with AGLE is this you know we're not a fan of trading stocks under a dollar okay she's moving unbelievable I don't know if they're oh it's a pharmaceutical stock too maybe they must have came out with something pretty good because it's up about 600% I'm not a fan trading stocks like this because what happens with these stocks you deal with tens of a penny all that stuff right there but I will admit you do get iceberg orders on the stock okay and you could see right here let me just show you here it's kind of hard to read so there was a big iceberg order right here you could see it right here around 10 cents we're already already at 1070 okay and zoom in over here a little bit a million share buyer of 50 cents you know it's kind of hard to read on the iceberg orders out here let me see if I can read it on NASDAQ book viewer AGLE is NASDAQ book viewer so you can see a little bit 18,000 30,000 yeah this is all you know like I said you're still getting orders on it and I would just be very cautious about it I mean some of you here have been for a while Brian so you know a little bit about it how to trade it but just be a little cautious on it this stock will probably would have been halted if the market opened up though alright now I looked over the New York stock and change I don't know if I really see anything there you got this stock of 3 million shares 3 million shares trade 11% but just kind of flat you know New York stock and change very very rare to find anything and then overall as brand name stocks I'm not seeing too much I mean Tesla is probably coming down a little bit it's been having a huge rally Pixie that's the one that we just found earlier just looking at the most active Nikola has been doing pretty well for us but she's kind of died out the last two three days pretty much does it ok so I don't really see anything more out there anyone else anyone else see anything out there that that we did not call out what do we got we got one two three four five stocks not the greatest list not the greatest but you know listen you know what happens when the market opens up there's always something that will show up alright alright so just let everybody know a couple of quick announcements remember you got we got class today phase one lesson three and four I will be at Nasdaq today so if everyone here wants to come and watch make sure you subscribe to our YouTube channel and our Twitter and it's going to be live on Twitter will put the post a link up there in the trading room and I told you if anyone here wants to come and join us you got that little qr code on a top left hand corner just take your phone and just click on it and go from there Kevin on YouTube just wants to be safe out so could you check out the QQQs so listen to QQQs I mean we had a big rally it's not really going anywhere when you look over here on the cheap little stock already hit 88 cents yeah so GLE just put it here 88 cents I think he's pushing the problem with the QQQs is this you're not going to see all the orders a lot of algorithms very difficult to see the orders out there and you're dealing with a 300 all stock you know what I mean it's all about less less risk more reward right Kevin a little slow this morning but we can change it could change any time Grant it's a very well said very well said alright so let's get back to the market opened up we got about 15 I mean let's marks we open up 15 minutes don't forget about classes don't forget about me I'll be watching my show me on Nasdaq and cyber traders you see something say something and one last thing before we go we had a lot of new members that joined us yesterday we did an eight o'clock event and we did a 12 o'clock you could always go back and review it if you're one of our new members here in the cyber group room please don't buy anything you're just here to watch just to see everything that we preached everything we talked about and see and put our money where our mouth is and most importantly to see the other traders know how to think for themselves because we're always looking to recruit new traders to be part of our family good luck everyone happy trading be safe and we'll see you back here at 230


You need a financial advisor with the freedom to focus on your specific needs. Whatever your goals, Reid Potter can create a game plan tailored to you. Call Reid at 432-0777 at Pikeville, Kentucky to learn more. So we got to come to Heinemann Settlement School today to celebrate AT&T delivering 75 free laptops to the students in the summer program here. And so there were 50 that were going to younger kids like middle school-ish age and 25 going to high school students. AT&T's $2 billion three-year commitment aims to address the digital divide by providing resources and connectivity to underserved communities across the country. These are laptops, 75 of them, that are going to be used by these students who participate in these programs and they can take them home. So digital inclusion is about access, about affordability, but also about adoption and having the tools to be able to navigate the online world. Speaking at the event, Lieutenant Governor Coleman emphasized the significance of this initiative stating we are all still working hard to bring hope and opportunity here. I think everyone knows that there are lots of challenges that people in the Kentucky phase and it's really been amplified by the flood that occurred a year ago and so we're just really trying to help children to have the same tools and the same opportunities that children anywhere else in the country might have and providing them with a laptop like this is really one of the ways that we can help do that. To see the looks on their faces and to have so many of those kids say, I've never had a computer before. This is my first computer. It tells you how important it is but also the connectivity that's going to teach them about with internet access, the responsibility now they have to take care of this device is even more important, I think, in some ways. Well, I came to school really not knowing really much that this was going to happen but all of a sudden someone said it and then I was very happy which this is late in the day so I can't wait to actually get this. The laptops distributed during the event were not only assist students in their summer reading programs but will also enable participants in the creative writing program to enhance their skills and unleash their creativity. I'm just so proud of Governor Bashir's commitment to continue to be an Education First Administration and what the pandemic taught us more than anything was the importance of connectivity and how much we depended on it as students, as employees and so we want to make sure that we bring that access all across Kentucky so we actually established the very first office of broadband that Kentucky's ever had for the purpose of continuing to deploy funds that we received from the federal government for increasing our connectivity all across Kentucky. Our goal is to bring high-speed internet to every corner of Kentucky for our students, for our workers, for our small businesses and for communities to have that kind of access that they've never had before. Lieutenant Governor Coleman's visit extended beyond the school's premises as she took the opportunity to announce nearly $170,000 to benefit Letcher County. These funds will be allocated to various projects aimed at enhancing the community's infrastructure, recreational opportunities and tourism. Reporting from Mountain Top News, I'm Ethan Miller.


Yeah, it's Like you like you mentioned I pitch a little differently than most guys, but I Really enjoyed just watching the physical gifts these guys are blessed with I mean I Just came off the field you know half an hour ago and Chad Green was throwing a Flat ground, you know, he's not even on a mound, but he's throwing pitches I would guess 90 miles an hour, so he's throwing stuff just casually harder than I've I can throw if I got a running start so You know, I just enjoy watching these guys up close and standing like I stood behind Nick Nelson throwing a Bullpen today, and it's just like my first impression was it is so hard to hit, you know, it's just Pitchers were so used to being on that that end that sometimes when we step on the other side and watch our teammates pitch I got to standing on Garrett's flat grounds today, too. It's just like I don't know how these guys hit it I really don't it's amazing I You know what I think I think they brought me in to help with with some of those the bridge the gap between the starters and and Chappy, so I want to be consistent. I want Booney to know what he's gonna get every day when he's put me out there and To me it doesn't matter if it's the sixth seventh eighth You know ninth if I need to it really doesn't matter. I've been fortunate I've pitched for a long time I've done just about every role you can do so I'm ready to go, you know, I'll miss Zach for for that time But I'll try to keep his his seat in the bullpen warm until he gets back


How many people know about the benefits of rechargeable 9 volt batteries? Hey, what's happening? NJRoot22.com here with another Tech Tip Vlog. And for anyone that doesn't already know, rechargeable batteries have come a long way in the past few decades. Back in the day, all rechargeable batteries were pretty much nickel cadmium. They were awful batteries. They were comparable for high drain devices and suffered from what they call the memory effect, which they totally forgot how much juice they had. The new standard for most rechargeable batteries is nickel metal hydride, NIMH. They have excellent capacity with no memory effect and they can be used hundreds of times and pay for themselves many times over. While we use nickel metal hydride batteries in mostly the AA and AAA formats, we never gave much thought to 9 volt batteries until recently. Now there are two kinds of 9 volt rechargeable batteries that you need to know about. You have nickel metal hydride and lithium ion rechargeable. Now just as a comparison here, most cell phones and laptop batteries use lithium ion batteries because they offer a stable voltage throughout the discharging process, whereas nickel metal hydride batteries, the voltage goes down as they lose charge. Now when it comes to 9 volt batteries, most applications are smoke detectors, tools and toys. We recommend getting both kinds of rechargeable 9 volt batteries, the nickel metal hydride and the lithium ion. And try them out in all your applications. See which ones give you the proper life because some apparently work better in some devices than others. But none of these can really outlast the standard alkaline battery from what we've seen. And also they have the super duper lithium ion non-rechargeable batteries as well. Some of them can last 10 years in a smoke detector. But the money saved for these rechargeable batteries is not a bad idea. You may want to use those long lasting batteries in locations that are out of reach. Lastly, it's essential to note that the various 9 volt batteries must be charged in their designated charger, otherwise you will run into a major risk of fire or even explosion. You can see this little chart here came with one of my recent purchases and it tells you clearly that you can't charge really any other battery. So that's it. If you haven't given 9 volt rechargeable batteries a whirl, it's worth looking into as we all don't mind saving a few extra bucks each year.
