Hello and welcome to the session. In this session first we will discuss limits. If we have that as x tends to a fx that is the given function tends to l then this l is called the limit of the function fx and this is symbolically written as limit as x tends to a fx is equal to l. There are two ways in which x could approach a number a either from left or from right that is all the values of x near a could be less than a or could be greater than a. So this leads to two limits the right hand limit and the left hand limit limit x tends to a plus fx this is the expected value of f at x equal to a given the values of f near x to the right of a and this value is called the right hand limit of fx at a then limit x tends to a minus fx is the expected value of f at x equal to a given the values of f near x to the left of a this value is called the left hand limit of fx at a then the limit of a function at a point is the common value of the left and right hand limit if they coincide and is denoted by limit x tends to a fx this is the limit of the function fx at x equal to a this happens when the left hand limit and the right hand limit of the given function at x equal to a coincides consider the function fx given by 2x plus 3 then x is less than equal to 0 and 3 into x plus 1 when x is greater than 0 we need to find limit x tends to 0 fx first let's find the left hand limit of fx at x equal to 0 that is limit x tends to 0 minus fx now in this case we will consider fx as 2x plus 3 because we have fx is equal to 2x plus 3 when x is less than equal to 0 so this becomes limit x tends to 0 minus 2x plus 3 then we substitute x equal to 0 minus h now as x approaches 0 h also approaches 0 so we get limit h approaches 0 2 into 0 minus h plus 3 that is this is equal to limit h tends to 0 minus 2h plus 3 now when we put h equal to 0 in this we get this to be equal to 3 so we have limit x tends to 0 minus fx is equal to 3 that is the left hand limit comes out to be equal to 3 now let's consider the right hand limit that is limit x tends to 0 plus fx now in this case we will take fx as 3 into x plus 1 as x is greater than 0 in this case so we get this is equal to limit x tends to 0 plus 3 into x plus 1 now here we will substitute x as 0 plus h as x tends to 0 h also tends to 0 so we get limit h tends to 0 3 into 0 plus h plus 1 now we simply substitute h equal to 0 in this and we get this equal to 3 that is we get limit x tends to 0 plus fx is equal to 3 this is the right hand limit so we get the left hand limit is equal to the right hand limit that is equal to 3 so we get limit x tends to 0 fx is equal to 3 next we discuss algebra of limits we consider two functions f and g such that limit x tends to a fx and limit x tends to a gx exist then we have limit x tends to a fx plus gx is equal to limit x tends to a fx plus limit x tends to a gx then next is limit x tends to a fx minus gx is equal to limit x tends to a fx minus limit x tends to a gx then limit x tends to a fx into gx is equal to limit x tends to a fx into limit x tends to a gx then limit x tends to a fx upon gx is equal to limit x tends to a fx upon limit x tends to a gx and also the particular case of this third property if we have that function gx is some constant lambda that is limit x tends to a lambda fx this would be equal to lambda into limit x tends to a fx if we consider fx to be a polynomial function fx is a polynomial function if we have fx is equal to a naught plus a 1x plus a 2x square plus and so on up to an xn where ai is a real number such that an is not equal to 0 for some natural number n then limit x tends to a fx which is a polynomial function is equal to f of a and if we have the function fx to be a rational function that is fx is of the form gx upon hx where g and hx are polynomials such that hx is not equal to 0 then in that case limit x tends to a fx would be equal to g of a upon h of a if in case we get h a is equal to 0 then we get two cases when ga is not equal to 0 and when ga is equal to 0 then we have ga is not equal to 0 and h a is equal to 0 then limit does not exist and if we have ga equal to 0 and h a equal to 0 then this is of the form 0 upon 0 then in this case we try to rewrite the function that is we factorize the numerator the denominator and we cancel the factors which are causing the limit to be of the form 0 upon 0 let's try and find the limit x tends to 3 x square minus 9 upon x minus 3 now when we put x equal to 3 in the numerator and in the denominator we get the form 0 upon 0 so what we do is we factorize the numerator and the denominator so we get x plus 3 into x minus 3 upon x minus 3 we cancel x minus 3 and x minus 3 and we put x equal to a in the term which is left that is limit x tends to 3 x plus 3 when we put x equal to 3 in this we get this equal to 6 so our answer is 6 evaluation of an important limit which will be used in the sequel is given as for any positive integer n limit x tends to a x to the power n minus a to the power n upon x minus a is equal to n into a to the power n minus 1 this expression would be true even if n is any rational number and a is positive let's evaluate the limit x tends to a x to the power 12 minus a to the power 12 upon x minus a this is of the form limit x tends to a x to the power n minus a to the power n upon x minus a so this would be equal to n into n is 12 so 12 into a to the power n minus 1 that is 12 minus 1 which is equal to 12 into a to the power 11 so this is the answer now we consider limits of trigonometric functions we have a very important theorem which is used in calculating limits of some trigonometric functions which says that let f and g be two real valued functions with the same domain such that f x is less than equal to g x for all x in the domain of definition then for some a if limit x tends to a f x and limit x tends to a g x exist then limit x tends to a f x is less than equal to limit x tends to a g x another important theorem that we have is sandwich theorem according to which we have let f g and h be real functions such that f x is less than equal to g x is less than equal to h x for all x in common domain of definition for some real number a if limit x tends to a f x is equal to l is equal to limit x tends to a h x then we have limit x tends to a g x is equal to l another important limit is limit x tends to 0 psi x upon x is equal to 1 and limit x tends to 0 1 minus cos x upon x is equal to 0 let's evaluate limit x tends to 0 1 minus cos x upon x square this could be written as limit x tends to 0 now 1 minus cos x can be written as 2 sine square x upon 2 upon x square now x square can be written as x upon 2 the whole square multiplied by 4 that is this is equal to 1 upon 2 limit x tends to 0 sine x upon 2 upon x upon 2 the whole square as x tends to 0 x upon 2 also tends to 0 so this is equal to 1 upon 2 limit x upon 2 tends to 0 sine x upon 2 upon x upon 2 the whole square we know that limit x tends to 0 sine x upon x is equal to 1 so this is equal to 1 upon 2 into 1 square which is equal to 1 upon 2 so this is the answer this completes the session hope you have understood the concept of limits


I'm Colin Daniels, I'm digital editor here at Ad Weekend. Today we have Craig Robertson of NBC and we're gonna be talking about diversity, LGBT inclusion and how we can best support the community. Craig, thank you so much for joining us today. Oh, thank you Colin, really appreciate the invitation. Can you explain to your role at NBC and what all you do? My official title is Executive Vice President and Chief Diversity Officer for NBC Universal. I get to work across the entire company, including Telemundo, our film, our television businesses to help make sure that we are fostering a culture of diversity, equity and inclusion, working with those business leaders to drive progress in their workforce to make sure that our content is speaking to an increasingly diverse domestic and global audience. Touching on the diversity and inclusion, I feel like no matter what one of your guys says that channels that you look to, you can always see various color representation, ethnicity along with LGBT representation, that such a cool aspect that a few networks, a lot of them can't do, but you guys just so organically do that. I would agree with you, and I think that comes from a couple different places. The company, going back over a hundred years, has a really unusual and groundbreaking sort of approach to diversity, equity and inclusion. We had Nat King Cole, the iconic singer and Christmas song, Chestnuts Roasting in an Open Fire. We had a primetime television show with him in 1956. Same time, same station. See you later. In that same year, he was doing a live show and was attacked by a white mob on stage. We knew that we had to start as a company looking like a country. Then if we take a look at LGBTQ, as you described, the first kiss between women was on, our network in the 90s, the first lesbian wedding was on, our show in the 90s, Will and Grace in 1998. And what seems sort of prosaic and normal now was controversial then, something that we are very much trying to do and we know there is certainly work to be done and that is this concept of something you alluded to, of casual inclusion. For so long, characters, whether they were black characters or Hispanic characters or LGBTQ characters or characters who were wheelchair users, the entire reason for their character revolved around that aspect when really in the outside world, you meet people who are multi-dimensional, who happen to use a wheelchair or who happen to be black. People fell in love with Jack as a character, so someone who may have had a negative feeling about people who are members of the community saw him and liked him and learned to love him and as facile as it sounds, it actually helps change people's perceptions. And you are far too young to remember this television show. Way, way too young, but somebody in your family will remember your parents or your grandparents and that is the show Julia. If you talk to anybody of a certain age in the black community, they will remember gathering around the television with their families to watch Julia because they were so proud to see themselves portrayed in that way much the way the LGBTQ community embraced Will and Grace and much as we hope and know they are going to embrace our upcoming reboot of queer as folk. It goes so far to helping people of any age realize that they are not alone and that there is life for you. When doing shows and creating like reboots like queer or spoken stuff, is there like a specific way that you guys kind of bring in the opinions of those in the community that would work for the company to kind of give their opinion, be like, okay, like this is something that we can relate to or these are some questions that I might have? These shows are very often almost always created by people who are members of the community. So they don't need a great deal of guidance. They're writing about their truth and we have a very, very large, very large and robust LGBTQ employee resource group and we selectively use the group oftentimes to sort of get their thoughts on some of the shows that we have coming out. But I have to tell you because the creators themselves are so diverse, they're getting it right. On the topic of Outer NBC Universal, I have to say that we were the first LGBTQ group to march under an identifying banner in the New York St. Patrick's Day parade in 2050. It made global headlines and it opened the door for other groups that have been trying to march for literally decades to then march the next year under identifying banner. What the organizers kept saying is, well, members of the community have been able to march forever. We've had LGBTQ people marching and we said, yes, but they couldn't say they were. There's a difference. Having that distinction and having so many of our senior leaders march with us is still one of the things that when I'm on the old-end grayer that I will sit back and look back and think as really a defining moment for the company and for our community. I know we touched on a little bit like Queer's Folk that reboot. Are there any other shows or any other initiatives that you all are working on that are coming up that we can all look forward to? On the film side, we have an upcoming release called Bros. And it is the first romantic comedy from a major studio that is about two gay men and their relationship. It's the first major studio film where every principal actor, whether they're playing a character who's a member of the community or not, is a member of the community. 10 years from now, we'll be talking about that and it'll sound quaint. But again, today it's rather groundbreaking. And are there any company initiatives that you guys do internally to celebrate diversity and inclusion, whether that's LGBT or through race and ethnicity? Like a lot of companies, we honor heritage months. One of the things that we decided this year was to take the month aspect out of it. We're not going to ignore it or put more emphasis in the month that is designated. We know the genesis of pride, but we shouldn't have to wait until June to talk about the importance of LGBTQ rights and freedoms. I believe we're still the only major news organization that has verticals on our digital platform, NBCNews.com. We have NBC Out, NBC Latino, BLK and Asian America. Those four verticals that I mentioned get literally millions of views is because they're part of the larger NBCNews.com and they rotate some of their primary stories on the homepage. So we're really using the power of the entire company to bring more eyeballs to stories that other people aren't even covering or many other people would not have normally seen. And my final question is if I'm a company or somebody who's like, I want to bring in that, I want to find what advice would you have for them who are trying to make an effort or who are now realizing after watching this, where it's like, oh, I'm not making an effort. Like what advice would you give them to try to seek that out? I am guessing that you have the resources right in your own company that you have probably not spoken to. Find someone in your company at whatever level and say, I realize, I know that I need to expand my list of contacts. How can you help me? What organizations do I not know about? Because there are organizations out there that will help connect them. But you just have to ask for the help. And I guarantee you that in any organization, there's somebody who is either involved through their own work, volunteering through, through their church, through their temple, through some other group who can connect them with people who can be helpful to being more effective, more diverse storytellers. Thank you so much, Craig, for taking the time to talk with us and interview people. Absolutely, thank you. Always a pleasure.


Well, yeah. The usual suspects are added again. Let's talk about Zelda's 35th anniversary. Let's talk about the games up on the screen, Twilight Princess HD, The Wind Waker HD, and why two video game journalists are still adamant these games are coming despite some issues. This year the original Legend of Zelda game reaches its 35th anniversary. While we don't have any campaigns or other Nintendo Switch games planned, we've been working on this game and watch system. Hey folks, so today we are starting a brand new giveaway. There's a link down in the description for it. We are giving away two copies of Skyward Sword HD. We will be announcing the winners of those copies the day before Skyward Sword HD comes out on July 15th next month. I decided to start the giveaways early instead of waiting for July 1st because well, I want to get the copies to people in time and I'm going to be gone at the end of July. So it would actually make not a lot of sense to keep running giveaways while I'm gone. How am I going to announce the winner when I'm out here? So we're going to have a Skyward Sword HD giveaway happening from now all the way through the 15th of July. It'll be every single video. You can get additional entries by commenting on the videos and all that jazz as well. So commenting, liking, all that. It'll be explained in the description. But good luck to everybody. Now look, I'm not going to sit here and pretend that all of our coverage of the 35th anniversary of Zelda has been correct over the last couple months. In fact, it appears none of it was correct. We have video after video reporting on rumors and reports from various game journalists and obviously other inside sources that told us a lot of different things were going to happen for Zelda's 35th anniversary. Everything from the pipe dream of Ocarina of Time HD and Majora's Mesh HD, which I was consistent in saying I didn't think was going to happen, all the way to things like things I thought were probable like the Wind Waker and Twilight Princess HD. Obviously we talked about the potential of a game and watch at one point, which we did end up getting and things like a custom switch system as a possibility, just a possibility not necessarily you know rumored and a bunch of other potential things in there or from the Oracle series and Grezzo doing things and the history that suggests that Grezzo has something in the works. Reality is that obviously none of this stuff has come to pass and well we can't dismiss the fact that the you know producer of the Legend of Zelda series could have been telling a fib to allow Skyward Sword to have its own little window of success. We also have to understand that at least as far as the facts bear out at the moment there are no further plans beyond the Zelda game and watch for the 35th anniversary. They didn't even label Breath of the Wild 2 or Skyward Sword HD as part of that celebration so those are just things that are going to happen. But what's interesting is a lot of the Twilight Princess HD and Wind Waker HD stuff had a lot of confirmation from things like Andy Robinson from Video Game Chronicle and Jeff Grubb from Gainsby to Video Game Journalists who obviously have reputations on the line when they talk about this kind of stuff. Now we all know investigative journalism and reporting is not always 100% accurate and plans do change. We need to be at least willing to admit that sometimes there might be plans and targets for things and those plans and targets change. We just have to look all the way back to the fact that you know Breath of the Wild was supposed to release in 2015. We didn't get it till March of 2017. So we already have public examples of plans changing let alone plans changing for things that are not yet announced. So yeah but obviously when we talk about this because we're about to bring up Andy Robinson and Jeff Grubb again because obviously they've been getting a ton of flak over the lack of Twilight Princess and the Wind Waker HD news. We have to take this in its proper context. They were wrong. They were also wrong about there being a Zelda 35th celebration. Beyond Game and Watch I suppose. So we have to keep this in mind because these two are at it again and despite being wrong they're doubling down. Now what does that mean? I don't know. Now my personal expectation is we're going to get Twilight Princess HD and the Wind Waker HD on Switch eventually. We just had Fatal Frame Maiden of the Blackwater confirmed it's coming to Switch and that is a game that didn't exactly sell that well and is on Wii U. I think it's just a no-brainer that the Wind Waker HD and Twilight Princess HD will come to Switch at some point. After all we've gotten a Zelda something every year of Switch. This year it happens to be Skyward Sword HD. Next year the plan seems to be Breath of the Wild too. So we'll see but here is what Andy Robinson and Jeff Grubb had to say in response to everything. We'll start with move with Jeff Grubb. He goes on the 15th and he said this shortly after the Zelda Direct ended or the Zelda Direct or the Nintendo Direct ended. He said I think we're not getting Wind Waker and Twilight Princess for the 35th because Nintendo isn't sure if we'll get Breath of the Wild 2 in 2022. So if it needs a Zelda thing next summer and fall it's good to have that in reserve. Still that's weird. I'm not pretending to have a perfect insight into Nintendo but this lines up with the company's recent strategy of holding these kinds of games even after they're ready. Pivot 3 Deluxe was done for months before we got it okay. That's his take anyways. His evidence is proof. Andy Robinson his original tweet back in February 2017 said for those disappointed with the Skyward Sword remaster Wind Waker and Twilight Princess are 100% coming this year. So that's at least one good 3D Zelda which I remember chastising and being like that's two good 3D Zelda's but obviously personal opinions there. That's what he said back in February. Well he looks like he's wrong. His response to that tweet on June 15 says update on this for everyone who's now flooding my mentions predicting dates is a fool's game and I should have never used 100% in the original tweet. Zelda fans sit tight. So he's saying hey you know what these games are going to come. They're just not coming when I thought they were going to come. And the problem I think you run into with people like Jeff Grubb, Andy Robinson and video game journalists is that they tend to and it's not just them. This happens with real leakers like Emily Rogers. This happens with you know other people even like Digital Foundry, Tom Phillips, Machizuki out at Bloomberg. What happens when they talk about these things is they have factual information but they mix in their own opinions right which is something we do as a YouTube channel. I understand you want to create a conversation and throw your opinion in the mix but you can't treat your opinion as if it's fact. As an example I've been predicting for a long time. This is just a prediction. I have no proof or evidence that SwitchPro if it does exist and does come out this year will be announced in September and release this holiday. I've been predicting that for a long time. This is despite Machizuki over at Bloomberg telling us we're getting it in September or October. So despite others saying it's going to be you know rumoredly announced before E3 none of that matters to me with my own personal predictions but this is obviously Andy Robinson going like hey you know this is what I heard and it's 100% coming this year and he's wrong. Now he's double announced it. Okay yeah sure I shouldn't have said that. Making it sound like he was just predicting it was coming this year when he definitively stated it was coming. You can't definitively state something. You know unless you want to say like it's your opinion like if someone asked me you know in a live stream, what do you think the chances are of Breath of the Wild to actually releasing in 2022? And I say 100%. Well the question framed my response. The question was what are my thoughts right? What do I think? So in that case it's clearly an opinion not a fact right? But that it gets hard when you throw an unquestionable tweet on Twitter like Andy Robinson did where nobody was necessarily asking him. He wasn't replying to somebody. He's just throwing out there it's 100% coming this year. You have to understand your rank and position. Me as a YouTuber if I say something like that it's pretty easy to point out it's an opinion but when you're an actual person who works in the video game industry works as a journalist in that industry and your job is to give factual information it comes across as well and as what it is and he never bothered to correct himself after by the way. He knew people ran with his tweet and were reporting on it including other video game journalists out that's like IGN and stuff and he didn't correct himself.  He let it go. Him and Jeff Grubb both let it ride. They let it ride. They didn't correct anyone. So I think it's interesting when you see these two people doubling back down on Twilight Princess HD and the Windbreaker HD coming out this year or coming out next year. Actually I have to feel like they're they're moving the goalposts right and you know this is where you get into a little bit of that Nostradamus effect where essentially you know if you keep saying and you keep moving the goalposts and you keep moving things you're eventually going to be right and it's just a very difficult world to live in because I don't really feel like Jeff Grubb and Andy Cortes were like trying to or Andy Robinson sorry was trying to mislead us. I think they truly believed based on things that they have seen or heard that it was coming this year and that we were going to get a 35th celebration even though that at this point appears to be not true. So obviously when we're talking about this kind of information I don't know. I mean what do people expect? I guess I could ignore these journalists but I also kind of look at things like hey look there are certain things I want to talk about and if a journalist is going to give me an excuse to talk about it I will. I do believe my personal belief my opinion is the Windmaker HD and Twilight Princess HD are coming to switch eventually maybe next year maybe 2023. I have no idea but that's just based on the track record of Nintendo porting basically everything we use including now Fatal Frame made into the Blackwater over to switch. It just makes too much sense that we've gotten all the other switch ports why would we not get these ones that you know it just I don't understand the logic behind it and very well Grezzo or somebody else could already be working on them I have no idea and obviously there are some theories out there that well maybe we are going to get them maybe Aegean Omo was telling a fib and once Skyward Story HD is out and then out for a month or two they'll drop the details of the next director or something that's always possible but again we have to work under the presumption that Nintendo's lying and the only evidence I have of Nintendo lying intentionally has been for things related to hardware anyways I don't know I'm curious on your thoughts on all of this it's always rough waters when you're covering rumors and stuff anyways right there's a reason I label everything the way that I do because I don't know that any of this stuff is true I'm just reporting what's out there and what it sounds interesting to me Twilight Princess HD and the Windmaker HD are very interesting to me they're some of my favorite games in the Zelda franchise and I obviously want to play them on my switch so if there's going to be stuff that comes out about it I'm probably going to talk about it like I just did in this video but this is with the context of these people were wrong but maybe they're right it's a fickle thing I do not envy their positions I don't know if I was of like a big video game journalist I would open my mouth as much as these people do it does create fun conversations however and it does give us something to talk about and I am you know doing this YouTube thing because I like having fun conversations and I like talking about things so I guess they're feeding what I like to do but are they necessarily feeding what you like that's a question I have for you what do you guys think about what these journalists are doing uh and obviously how I'm handling it and other content creators handle covering them because is it what you want I don't know let me know down in the comments I am with interrobang that's from the center prime I want to thank you so much for tuning in and I'll catch you in the next video


Welcome back to our meds smarter lecture series where we're taking a smarter approach to preparing future physician Before we get started if you'll take just a quick minute and click that like button and also Subscribe and turn the bell on so that you'll be notified when we post new videos. So now that we have processed T cell activation. Let's talk about how we activate B cells and undergo class switching So what happens first? Well, our T helper cell is going to be activated as the T cell Occurs and then our B cell receptor mediated endocytosis occurs Okay, so we're taking that activated T helper cell and we are activating our B cell by Presenting an antigen to it that is going to endocytose that particular antigen into the cell, okay? So step one Step two and Then we have exogenous antigen being presented on an MHC2 and recognized by the TCR of the T helper cell step three is going to be Right here in the middle. So we're taking that antigen. We're presenting it on the MHC to Our TCR on the T helper cell all right and then step four here our CD 40 receptor on the B cell Which is over here on the right and white is going to bind the CD 40 lag end on the T helper So which is the green square structure on the left? So step number four is where we have that binding of the CD 40 receptor and the CD 40 lag end between the T helper and the B cell Then on step five our T helper cells secrete cytokines that will determine the immunoglobulin class switching of beta cells So coming out of the T helper cell are these Various cytokines that are secreted that will then determine the type of immunoglobulin That the base that the B cell switches to so this is step number five and then the final step for class switching of B cells Activating the B cells undergoing class switching and affinity maturation and beginning to produce antibodies So all of this will then move forward to produce those antibodies Step six so we just talked about how our antibodies are created undergoing class switching using T helper cells B cells So let's talk about the actual structure and function of antibodies First and foremost on the right here in this picture. This is what an antibody looks like We have several different components to it. We're gonna talk about that right now. So our fab Area or location is over here on the right side. It is the two Arms of the Y if you look at this it does look like a Y The two arms of the Y are going to be our fab and this is where our variable hyper variable regions occur We have a light and a heavy chain that will come and to recognize our antigens So the light here is going to be the L's and the H is the heavy So you have two heavy chains two light chains that all compose the fab of an antibody Beyond that our FC region is the post of the Y or the long arm of the Y and that is down here it goes To the region of IgM or IgG and it fixes complements heavy chains here Contribute to both the FC and the fab regions. Okay, so your heavy chains make up that long arm as well as the Forks All right So you have two heavy chains make up the long arm and the forks It is the long ones and then your light chains is only found in the fab region Over on the outside as they interact only with the heavy chains in the fab region What does fab mean? All right, this is fragment antigen binding. Okay, so what does that tell you? That tells you that in this region up here is where the antigens are going to bind. All right So if you can remember fragment antigen binding That's where the binding occurs of the antigens that will then go with the FC region to present those particular antigens To IgM IgG and fixed complement. All right, let's look at the FC region a little bit closer here The FC region has what we know as the five C's Okay, the FC region is constant. It doesn't change. It doesn't matter. What antigen we're talking about It doesn't change. They will always be the same. It has a carboxy terminal end Okay, it binds complement. So there's your fifth C of complement binding it has carbohydrate side chains that help compose it and The FC region confers the isotype. So are we talking about IgM IgG IgD? whatever Those are the five C's associated with the FC region of the antibody If you found this material helpful for your studying, please like and consider subscribing to the channel Also, share this video so that more people can benefit from it like you have


It's time for Mackie Gabb and listener Bruce brings us our quick tip of the week with a follow-up from last week There is a very simple way to show or hide normally invisible files in the Finder and that is by pressing command shift period More quick tips like this plus your questions answered today on Mackie Gabb 9 79 for Monday, May 1st 2023 Looks and welcome to Mackie Gabb the show where you send in tips like that and it was That that particular tip came from Bruce and Eric and Ben and Wayne and so many of you I missed it during the show because I wasn't paying attention Next time I endeavor to do better, but you send in quick type quick tips like that We share your quick tips you send in your cool stuff found we share cool stuff found you send in your questions We try to answer your questions. We stitch it all together into an agenda and the goal is such that by doing all of that and Following through the agenda we each learn at least five new things every single time we get together Sponsors for this episode include collide comm slash mgkolide.com slash m g g We'll talk more about what you will get when you go there But it's awesome zero trust tailor-made for octa cool stuff For now here in Durham, New Hampshire. I'm Dave Hamilton And here in Fairfield, Connecticut. This is John of Brown and here in lead in Hampshire's pilot Pete listening to the British jets going home overhead.  Right kind of down the road from us both. So all right. Let's Let's get into this cool stuff There's quick tips here because we have yet another follow-up In fact, we've got some great quick tip follow-ups here. We were talking in episode 978 about The the tip for moving messages moving among messages in mac os and using control tab or shift control tab And scott says rather than using control tab, which I find unnatural to use within an application He says I use it to shift between applications I simply changed the keystroke in settings keyboard keyboard shortcuts app shortcuts messages to use command up arrow and command down arrow That makes more sense to me. This is one of the coolest things about mac os that you can set Your own keystrokes to do things and you can make them system-wide Or app specific so that they aren't getting in the way of what command up arrow and down arrow do in other apps It's very cool. And and then he shares. I like that So thank you for that scott. He also shares a bonus tip, which is sort of a quick tip revisited He says if you've got contacts pinned You can use command one through command nine to access Up to you know, you can have nine contacts pinned and or And you can access them that way by the way pinning contacts is not just about Individual contacts you can pin group chats as well So if you have a like a family group chat or a work group chat That you want to pin you can pin that too It's you can anything that's a chat can be pinned so Hopefully lots of quick tips there for you. I don't know. Yeah, that's what I got. Yep That's what we got for today Uh, actually, no, that's not true. We have more john. We have one from henry also a reference to show. Yes, we do Um last week's ios safari tip reminded me of another feature available when the address bar is fully visible If you swipe left or right on the address bar You'll switch to your next or previous tab and if you're on the very last tab swiping left will open a new tab You can tell you're on the last tab if there is no hint of another address bar peaking into the right of your current address bar By the way tapping on that little bit that peaks in will also take you to the next tab Similar thing on the left for previous tab, but those require more precision Than swiping. Yeah, I find that harder to do Interesting. Yeah. Yeah, and this is on iphone. Uh, and maybe ipad. I can't remember how Probably not ipad because on ipad you actually get to see your tabs at the top. So yes, this is on iphone. Yeah Yeah, I like uh, that's good. That's good. Yeah, I um I like it all um I noticed the other day if you are If if you are a twitter user who recently lost your ability to use sms for two factor authentication If you like had a check mark before and then it went away Uh, you now you need the the check mark in on twitter in order to have two two factor authentication Using sms and so it will force you the next time you log in after you lose your check mark to uh To to to change that or if you haven't been using it, you can't use sms unless you pay the eight bucks a month However There is still the possibility of using two factor authentication on twitter You just have to do it with like the you know the the one time passwords And I think maybe there's another way to do it But I you know, I just changed mine to using one time passwords which for me I store in in one password And uh, and so now I'm back to having 2fa on on twitter and you don't have to pay for the the privilege I guess sms messages probably cost them something in fact. I'm certain they do that's sort of how that works So they probably limit that to just people who are paying them But but you can still do two factor authentication on twitter just You have to You have to go in and actually do it again. So it was not obvious to me the path that they sent me down It was like, oh, you just lose the ability to do 2fa. I'm like, I don't like that that sort of worries me Well, good news. You can go get it back. Just Just knock on the door a little bit harder I recently guys, you know, I've had fiber for a couple of years john mp I recently changed My connection I moved it as I mentioned I think on the show from the office over to the house because the house has the generator and I just want all the network Gear over there so that I don't have to deal with you know, it just has an automatic generator So all good to go. So in doing that I moved from Even though it's sort of the same provider They changed brand names I moved from having a ppp oe connection To having a dhcp connection which All else being equal is way better. My ip address doesn't change three times a day anymore. In fact, it doesn't change at all anymore I don't need to have a router that supports ppp oe even though I still do right like it's a it's a better way of Going about it. The one thing though is that unlike cable modems The fiber at least my fiber connection and for those of you that I've talked with who are also using dhcp on fiber The fiber connection Stores your the mac address the hardware ethernet address of your router In the provider's database and the provider is the only one who can change it, right with a cable modem Your cable modem grabs the the mac address when it powers up And if you need to change like if you get a new router You just power cycle your cable modem and then it lets you put your new router in no problem You don't have to make any phone calls. You don't have to open a support ticket With fiber that is not the case. You do have to open a support ticket to change Well, I mean fine But I knew this going in and so what I did was I asked the the tech Because I could I could have gotten this information myself But it's way better if I get what they think my mac address is so I asked the tech I said Tell me what your system says my mac address is now that I'm set up with my router and all of that stuff And he was like sure, you know, he showed it to me on his computer screen and I put it in my Entry in one password that also logs me into You know my provider's website like to pay the bill and all that stuff And so now I have the mac address for the Device that is authenticated to use on my account Most routers will let you do what's called mac address cloning So if my router blows up and I need to put a new router in I know what mac address to tell it to masquerade as to let me back in So you don't have to open a ticket So I don't have to open a ticket at 3am on a sunday morning when I have no idea if they're going to be there to answer and and help me Right So well, that's great. Yeah, can I go get mine off of my Can I just look at my I should be able to look at my router see what the mac address is and that would be it right Correct You just want to make sure you grab the mac address of the wan port that you are using Some routers have multiple ports that can be used for the the wan Like the Synology routers for example have two They have two and one of the here's a here's another, you know So now the tangential quick tip on the Synology routers Uh at least the rt6600 the current one The uh, and this is probably true of others There's one wan port and then there's a four port switch for the LAN Right port one on that four port switch can also be used for the wan if you want to have like fail secondary backup or Yeah, in your case you were using cable and I was I've I've I've turned off cable. I have it all wired up It take it'll take me a couple hours to like call them and have them turn it back on I wanted to stop paying them 40 bucks a month. So it's fine um However, even without using a secondary connection. I'm not using my wan port I am using my LAN one port for my fiber connection because That port is the only port of the five on my router that supports 2.5 gig ethernet and my Device from my my provider also supports well, it'll support up to 10 gig ethernet So I figured why not give it the head room I don't need these other, you know, I don't need the one port there. I connected to a bigger switch anyway So That's why I can't just read the bottom of my router and say I know what my wan ports IP mac address is I do know what my wan ports mac address is But that's not the one that my fiber provider knows because I've they've never seen it Well, is the so that begs the question for me is is the other one Is that limited to one gig? It is It is unclear in the documentation I had to ask support this because I was like, I think there's something broken with my router I'm like, I'm only getting 2.5 on the on the LAN one port not on the wan port. They're like, you know, that's as design Like, okay. It was just worded Yeah, flip that around you'd want your Wan port to be the one that handles the most traffic in your backup to be if you got a limit one Here's why it's not I think I didn't ask them this once they confirmed for me that it that it was what I was seeing I was like, okay, great. I know what to do. Perfect. I'm on it the reason I think that they do this p is because That way you as if they're only going to pay to put one 2.5 gig port on there by putting it as the first port of the the the you know the the LAN switch And giving it the option of being used on the wan you now as the user have the option of saying, okay I want to use that 2.5 gig port for my wan or I want to use it for my LAN connection because maybe I want to plug it into like a network storage device that Uh, that would benefit from from having that right and arguably that might be the smart move for me too Like I I don't know that I would ever wind up using more than One gig, you know on my internet connection Whereas maybe I would use more than one gig on my on a NAS drive Yeah, because because even though the rest of the ports and we'll get into this a little bit here just to explain But even though the rest of the ports on the switch are only one gig per second if you have Two devices connected to you know each port Then each of those gets one gig per second And that means they can each talk to the 2.5 gig port at their own full speed So assuming the device on the 2.5 gig port is capable of transmitting data You know of like the hard drives on your NAS can can you know generate data that fast then great Okay, you could you could talk to multiple devices at at full speed Gotcha, does that make sense that does actually yeah, okay that at first it didn't it's like well That's just silly. Why would you not have your your wan port being the fastest one? Oh That sound means I get to tell you about our sponsor collide and they have some big news If you're an octa user, they can get your entire fleet to a hundred percent compliance How well if a device isn't compliant the user can't log into your cloud apps until they fix the problem It's it's that simple literally collide patches one of the major holes in zero trust architecture Device compliance without collide it struggles to solve basic problems like keeping everyone's os and browser up to date Unsecure devices are logging into your company's apps because there's nothing there to stop them Collide is the only device trust solution that enforces compliance as part of authentication And it's built to work seamlessly with octa the moment collides agent detects a problem It alerts the user and gives them instructions to fix it.

I think jed has jed found an interesting thing Yeah, I've actually run into this myself, but um Jed says just wanted to send in this warning question mark So I have mint mobile and never needed a lot of data But last fall in this spring. I'm noticing that if I have maps on for an hour or three and a minute and I'm driving kids to various sports and social stuff. My data hit its cap I just checked the map eight Up 20 gigs this weekend. That's in like three to four hours. So I may be going back to ways or google maps Just thought I would let people know Um, and yeah, you can see this dave if you go to um, uh Settings cellular it'll list Your various apps and how much data they use and and I actually had Had this happen when I switched over to 5g all of a sudden I blew my data cap in like less than an hour Is that because you were doing a bunch of speed tests? No, no, I wasn't oh No, and then I looked and I I did the same thing, you know I looked in settings cellular and weather was taking up gigabytes of data. It's like why Yeah, I remember you saying that now. Yeah. Yeah. Yeah, that's interesting Fascinating Huh The only time I had maps take up data like that was like on a long road trip You know last summer we drove to florida It it but I don't I don't recall it hitting my cap right away I mean I hit the I hit the cap that month and that's why I switched on limited like that So you did so probably but maps um Maps chewed up that much like gigabytes of data I think what it was is we were just on the road for two days and And so I wasn't on wi-fi and so you know, I tend to like for instance, uh I listened to sirius xm Cheap cheap cheap pilot not that not that audio takes up a lot, but cheap pilot trick here folks So we pay for the sirius xm from a wife's car And so I get the app on my phone and I listened to sirius xm on my phone Using apple carplay so why pay for two radios when you get the app and an apple carplay Yeah, they're probably gonna hear that and shut that down now. No, I don't know how they could but um, yeah, that's right No, that's a smart. I like that tip. I like that. Yeah, I I I can't imagine why Maps would use gigabytes of data like this like it doesn't It doesn't make sense to me We haven't heard if if others are out there seeing that they'll let us know feedback at mackeycap.com like We definitely want to know Where feedback at mackeycap.com Feedback at mackeycap.com. That's true um I when when his email came in I looked because I just reset my cellular stats, uh, two months ago on February 22nd So about two months ago, uh, and I use maps almost exclusively While driving right it is my mapping app Um, and I have the same provider. I use mint not that that's relevant here, but um in two months Maps is used for me a grand sum total of 500 less than 500 469 megabytes of cell data Um, and that's in my top 10 apps, right like in terms of data usage And I've done I did a trip down to new york like I've I've done some longer road trips But I use maps all the time So I'm just I'm I'm curious as to what it would take to get it to burn 20 gigs of data. That's interesting That's a lot my my biggest one for the last two months is speed test At 2.2 gigs speed tests, especially on 5g if you're getting um You know if you're getting that that you know 100 to 200 to 300 megabit per second connection That will chew up, you know a quarter gig per speed test Uh, just why I yeah interesting and by the way Uh the part about being on mint mobile that is relevant is You know mint is a a an mvno for t-mobile meaning they use t-mobile's network, right? Because they're an mvno, there's some part about the deal I'll say that means they Can't or don't Show when you're on 5g versus the 5g uc or whatever t-mobile calls it like the the ultra wideband, you know, whatever Whatever that is, but mint does support the 5g uc or uw or whatever it is. It just doesn't show it On iphones, you know like it does if you had a t-mobile connection You'd either see 5g or 5g uc. I think john m verizon uc 5g and 5g uw I think but uh he'll he'll confirm eventually Yes, I've seen that before yeah um But like though you do get those speeds with mint even though you're not seeing the the distinction happen it with the 5g Thing and so yeah, I've I've had some speed tests on mint that are like over 400 megabits per second on 5g Which is amazing, but that's why I burned 2.2 gigs One other thing about maps though briefly is that uh, that they're slowly getting the functionality of ways I've gone off of ways they they alert to speed checks and hazards and that sort of thing. It just needs more people playing I report the hazards report report the speed checks. Yeah, although, you know syria and her infinite lack of wisdom Spirit, you know, hey syria. Oh, sorry. Hey, yes lady, uh Speed check at this location Yeah You deserve that pete. Yeah, I did For those that didn't hear it. She said that's all good. Yeah, thanks a lot. Yeah. Yeah. Yeah, but yeah, you'll you'll say. Yes lady Speed check at this location. I can't show you that while driving. It's like oh dear god make it stop Make it stop. That's right. Yeah. Yeah I'm trying to figure out where I was when I just recently got a A speed test for it was like 420 megs a second. I think it was local here. It's maybe boston or something, but Yeah, you can 5g 5g can be fast. It's fun. Yeah. Yeah yeah All right. Well, if you do see the maps using that up folks, let us know like this this would be an interesting data point But I'm hoping that it's unique to jed and especially hoping that it was unique to just that weekend for you jed Not happening all the time Uh, we got a couple of follow-ups about our discussion on tail scale in 976 Uh, including a big discussion Kind of follow on discussion in our discord channel, which I'll I'll put a link to but um You know, I talked about in 976 how I'm using Tail scale to get to my specific machines and then how I have my Synology vpn for if I want to get to the whole network and then I have You know a separate vpn I use private internet access if I just want to get to the outside world and not deal with, you know My home network or whatever And many of you including robert pointed out that you can Use tail scale to To be that outward vpn And it's You set up one of your devices That's you know, sort of permanently at your house or office or whatever You use tail scale and you set that up as an exit node And what that means is that not only can it be a device that you can just attach directly to That it can also be your path out to the internet just like a normal vpn And the nice part is you don't have to set up a normal vpn You don't even have to have a router that will let you do that because tail scale will do it So it just needs to be an always on device So your network if you have a nas like a Synology distation or something That's the perfect place to do it But it gets even better and this was the part that blew my mind when somebody Really explained this to me in a way that it finally sunk and it was I think mq richards I want to say in our in our discord. I can't remember off the top of my head Something like that The the post is out there. So you get full credit but The idea was you know, you don't have to put tail scale on all of your computers You only need to put it on one device in your network and the reason is It supports something called being a subnet router And what that will do is let you connect use that one tail scale device to be the gateway to your network Which means that not only do you not have to install tail scale on all your other devices You don't need to meaning you can access devices like printers where you couldn't install tail scale Anyway, even if you wanted to so you set up the and and and The idea is you really only need to set up one device at home with tail scale Turn on exit node and subnet routing capabilities for it And there's docs about how to do this. It's really not all that complicated and then When you're connected to your tail scale You can you're you know, you're going through a vpn if you want to get to the outside world no matter where you are and you can get to your inside world just by Without needing to put tail scale on anything. So I immediately did that I'm going to stop running tail scale on all of my computers except for my my Synology disk station and and that'll be that but It's kind of blew my mind that this is the right way to do this It makes life way way way simpler because you can just be connected to tail scale all the time on your phone and your laptop And no matter where you are You just get to all your devices as though you are at your home or your office wherever your primary network is Does that make sense peat? Did I did I explain that right? Pete you are muted that there's I knew you were trying to talk to me Yeah, kind of lost me a little bit but okay, it's that's why I asked yeah So So I have it on the Mac mini in the basement and that's the one I run is perfect node when I run when I want to run it right um But I have to have it on my laptop if I want to be on that network Correct, okay, you would you would want it on your mobile devices your laptops Your phone my iPad your phone your iPad the things that aren't that are going to be traveling away from home with you But and I need it on my on my Synology drive my NAS drive in order to See that's what I'm saying It with the subnet router you don't need it on more than one device At home because if you let's say you make your mac mini right your tail scale device And it can be your exit node if you want it to be you turn that on or off And you if you go enable subnet routing now that mac mini will not just be a gateway to the outside world Aka the exit node it will be a gateway to the inside world via subnet routing It they use that subnet routing is the wrong term right exit node For some reason like the english equivalent of that makes good sense It should be an you know inbound node, right? So it is just the path to your network and then you use your your local network ip's and you can get to everything From wherever and it doesn't matter where you are right. Okay. That's beautiful then because correct I mean I still love it because the fact is You know with my other show I put I have a ton of data. Well, I need to offload that from my laptop So that I don't have gigabytes and gigabytes of of past shows that I don't have anymore So I put that on a NAS only folder But I can't access that from the outside world until tail scale came along last right Now I can get to it from anywhere in the world and I there is no harm In it that I found in having tail scale on more than one device in your network So what you're doing with it on your mac mini and on your your NAS like there's no reason to stop that necessarily But there's also no reason to set that up necessarily you just set it up on one And then add this subnet routing a k a the inbound node And and then you could hit you via your mac mini you could access your your Synology all the time anyway Then let me ask this and it may be because what I do now is I go to the tail scale app Yep, or you know right up in the top in the menu bar and I go down to Network devices my devices Yeah And it shows my disk station there I click on that and it copies the IP address of my disk station Then I go to finder and I hit connect and I use that IP address. I no longer need to do that. I can just go to my 168.4 Correct. That's correct. You would use the same local IP address Whether it was whether you're in Dubai or in lee new Hampshire or in the living room. Okay, correct Yeah, Dubai or the living room. That's a much better way. Yeah, see that's that's the marketing phrase right there Yep, okay Yeah, it right it it it keeps you from having all these different addresses for the same devices All that being said Because of the Boy Scout enemy always be prepared right, uh If you are if you know that you're going to be accessing your Synology a bunch from remote You don't and and you're going to need to rely on that because of this data folder that you said you had out there I would not be too Hasty to remove tail scale from the Synology because Once you do it is reliant on your Mac mini being up and running and not having crashed or you know, like Murphy's law, right? So yeah, so like There's a world where it's okay to do both is I guess what I'm saying Yeah, you turn the Mac mini off. It won't work Correct, but leave that on there. It'll work even with the Mac now you got to back up, right? You know, so yeah, yeah It's still it says that these guys at tail scale are brilliant They are yeah, they um, we have a question in the the chat at mackeykev.com slash discord from uh p.m. Conaway Saying uh, can you only use those features if you have a custom domain? I'm using a google account No, I am also using a google account and a hundred percent of the features. We've just talked about work So in and most of us who signed up for tail scale early on Are doing the google account way because that's the only way it was possible to do it early on Now you can sign up with a custom domain and in fact, they just came out with new pricing plans That add more features to all of this including Giving you up to three users for free not just one user for free, which is huge However, those of us on google accounts still only get one user for free Because you have to be on a custom domain to add more than one user to your account And I believe somebody please correct me if i'm wrong that All of those users need to be on the same domain That's how it does what it does and this is why at the moment anyway, they're working on it They say but at the moment you can only have one gmail User per domain because otherwise they would let every gmail user gmail.com user Onto every other gmail.com users account and that would be Super bad. So they're not doing that now that being said my wife has a separate Computer her own iMac And I just put my tail scale account on there. So I don't need another user Correct if you're fine with someone having full access to everything and also being logged into your google account Which is fine with your wife and then you're great. Yeah exactly exactly And you could get creative and and create a second gmail account That's only used for these purposes and then it doesn't matter. Yeah, but I just got an idea though Mom's 97 lives in a nursing home Her only connection to the outside world is the ipad and that thing is always giving her trouble I need to put tail scale on her ipad Yes, so I can give her support remotely Yes, you know, it's frozen up. I can't get email to do this or that. Yeah, yeah, you can let me hang on mom I'll take care of that. Yeah. Yeah, right right right. Yep Yeah, no tail scale Thank goodness for tail scale. They also it's worth reading their article again It's linked in the show notes at macgeekab.com or mgg.fm slash 979 if you want to go right there And it'll be in your email box if you sign up for our weekly emails at macgeekab.com but they talk about why they are able to offer a free plan for free and how that works and how they are able to Not just make you the customer or you the product, right? You are we are still the customer They know that by doing this They see more uptake on their paid plans and and so it's the freemium model not the We're going to sell your data model. Uh, and they're very transparent about all this So it is worth giving a good read All right, um More questions, let's uh, let's go to craig here Craig says Does anyone use the logitech circle view home kit camera? We have a few and all of them cut out daily showing no response The fastest and only way I've found to resolve it is to switch off the power Uh, you know cycle the power on the camera and that works every time until the next time It's not ideal, especially if we're away and I can't access the plugs I'm considering buying a couple of wemo smart sockets. So if we are away theoretically I should be able to turn them off and on remotely to solve the cut out problem If it happens while I'm away. Does anyone else? Have these cameras have you had this problem and have you found a solution and several of you? Uh reported using these cameras and seeing this exact problem So maybe not so many of the logitech circle view home kit cameras need to be purchased going forward That's a little psa Anecdotally anyway, you know, there's there's like four people. So, you know Factor that into your your purchasing decisions I have found this though That the the symptom that craig Highlighted is that he goes into the home app and it says no response on the kind of the You get that main sort of dashboard screen, right? And you see your favorite devices and your cameras and all that stuff on the on the dashboard screen for home kit Uh The cameras will say no response there. I see that sometimes with the cameras I have I have a combination of ufi cameras, which are, you know, direct to home kit support and I have a bunch of non Home kit cameras like ring and and like a fos cam camera and and others that I use home bridge to connect to home kit and Equally with both of those the ufi home kit cameras and the non, you know via home bridge cameras I will Routinely see the same no response in the dashboard However, if I tap on the camera and force it to go and like try and talk to the camera It wakes right up and I see the image live right there and good to go. So There is something about home kit being perhaps impatient on waiting for a response back from the camera I don't know what it is But if you do see this issue before you presume that you have a camera that's just bogus Tap on it and dig in and see because You might you might be pleasantly surprised. You might also be, you know Unpleasantly frustrated. I can't promise what's gonna happen. I can just share what happens with me and others that I know Do you use any home kit cameras Pete do you use home kit at all? Uh, I don't I need to okay. Um, I don't know. I don't know. I I don't rely on home kit I use home kit as sort of the convenient aggregate of all of the other things that I use because Like sure, I could run the ufi app or the ring app to see Each of you know, the separate cameras that I have in those obviously But launching the home app is super convenient because it I have everything aggregated there I've set up home bridge, which is a Open source engine. I have it running on my disk station, but you could run it on your mac I'll put a link in the show notes So I have home bridge running which which essentially becomes a gateway for all non many not all most most non home kit devices to be Visible in and controllable in home kit. It's it's quite nice. So I use home kit as kind of the the the convenience Default way to look at it. It's nice because it's available on my max And so I don't have to have the ring software on my mac I can just launch the home app and see things But it's kind of buggy is as bryman row in the chat says Home kit is just buggy garbage. Well, that's true, but it's convenient garbage It's right at the tip of my fingers So I but I wouldn't rely on the home. I may have misstated the home app is different than home kit No, no the home app is your view into home kit. Okay. Yes. Yes. So well So I misstated it then I I use it a little bit when s lady won't turn off a later turn on a late I can open the home app and go all right, you know, let's go my favorite one is hey s lady You know turn on the living room lamp and I get the error the google I don't know why you get that error. I've seen it too. Yeah, you get it more than You needed to have installed to make this work isn't there. I'm like that has nothing to do with google It's a it's a phillips hue light And I just told s lady turn it on and she wants a google app for it. I'm like, no The phillips hue light is home kit native Yeah That's why it's particularly frustrating That was a really kind way of communicating that sentiment piece Okay, you know, yeah, so I do want to take a baseball bat and go hit that home bridge down in the basement and Yeah, yeah Yeah, yeah Yeah, no home bridge has been great because again, it just sort of aggregates all these things together and it's Now that they have Native home bridge for Synology. I don't have to run it in a docker container and manage that It's an I don't think I should say that but I I'm pretty sure yeah um Now that they have that I think it's through Synology community or something like it it really is not It it it's not for The faint of heart. I'm gonna say that but it's pretty good You know, there's some of the configurations of getting it set up with each of your Different things is a little bit of a deal but you can do it if you're listening to the show You can do it. I have faith in you and if you have any trouble come to our discord and ask I'm there, you know, there's others there using home bridge. Like it's a good place to it's a good resource that like Yeah, what I haven't done yet though and I had a discussion when I was down in Tennessee with my nephew this week And he's gonna he's getting ready to do it and I went, you know, that's not a bad idea It's setting up a DMZ and putting all those internet of things devices on that Separate from you're talking about a guest network not yeah Not a DMZ is sort of the opposite of what you would want to do right Okay, well, I think he used the term DMZ, but I'm thinking okay I want a zone where I put where I put all those internet of things that can't access my network Oh, yeah, no, that's not what most routers what DMZ means Is and it's it it's, you know demilitarized zone is the term and so this is already a misnomer But fine, you know is it is a way of setting one device as The one that gets all of the traffic that just floods into the outside of your network that your your router by nature of its sort of de facto firewall capabilities keeps out like normally Unsolicited packets that arrive at your router's doorstep are just Ignored because your router doesn't know what to do with them, right? You know unless you've set up some port forwardings then it'll forward them But a DMZ on most routers is port forward everything that I haven't told you about to this other device and let it handle it Okay, so it's a missed misstatement of terms that yeah, but what it what it sounds like he's doing is setting up a separate You know a a a guess network. Yeah, like yeah a guess network or or you know some version of that where it's it's Segregated so that those things can only talk to the outside world and not impact his other devices the problem with that I've always had is What convenience are you giving up for that with something like a ring camera for example?  It works totally fine Like it's it's it's great. So that would work fine But what if you've got a device that's like, uh, you know a foscan camera or something where it can do both And you can talk to it locally Which would be all of your home kit devices you're talking with locally Right. So, you know, you're you have to get on that network in order to talk directly to Correct instead of your Yeah, so I I've always sort of felt like That's a it is a solution But it's a baby versus the bathwater solution. You're just like it's your you know We talk about the the continuum between security and convenience and that's way closer to security than convenience Well, and you and I have a different and john we have different Needs, I mean in the show that that we are Isolated enough that uh, that there's not a lot now He's in a in an apartment slash townhome complex where there's a lot of wi-fi networks able to interact with each other and People can they're gonna interfere with each other, but they're not going to interact with each other.  They're better now early on they were totally open Totally. Oh, and that wouldn't whether you're you know alone in the country or in an apartment building like the The easiest attack vector is the same. It's come in over the internet And poke that hole in your You know off-brand camera or off-brand printer that has you know, security swiss cheese in its default linux core Embedded linux core that where all the passwords are you know like defaults or whatever And and then it has and then once you're in once you you know have root access on that device Then you you know and presumably that device is connected to the network now you have access just like you're on the network So that yeah that issue I mean it's still potential Today, but as you said like many most many I don't want to say most many including most of the The top name brand vendors have gotten better about this, but there's still those holes So I get it like I get the desire of doing this you just I don't know it it feels like more trouble than it's worth for most people Yeah, interesting. Yeah, interesting point. So I'm actually glad I brought it up now I see less of a need for it than than initially when he mentioned, you know, yeah Yeah, I mean if there's a need for it, but it's gonna introduce complications that You can route around but it's you know, it's gonna be You're gonna be the one. Well, here's what's gonna happen. Let me tell you folks.  What do I need to do? What do I need to do? So I stop everything I'm doing and and then we try and figure this out and I Ask well, what did you change? I didn't change anything and then you know within about 15 minutes We get to well, I mean I I did that thing that I mentioned on the show. It's like that that's when I that's when I hit my Particularly frustrated moment. We're like, what did you do that? Right, I told you you idiot I told you not to do that I told you so You know, it's just one of it's like but it like this is true of all of the things that we all do all of the time I mean, thank you for letting me, you know, use you as the the punching bag on that one, Pete But like this is this is the the the thing is you you presume some of the ripple effects of the the changes that we make to our networks and our computers and our phones like any device And then there are the ripple effects that actually happen the ones that we didn't predict and That's why this show exists. So you send your questions in feedback at mackeykev.com. It's great.  All right, john Maybe we can do a couple more questions before we have to run today. This has been fun Uh, do you well first do you have like do you how do you use home kit? Uh, no You See see how john see what john just did I intentionally didn't ask a yes or no question and it didn't matter. It didn't matter. I love it No, I really really don't use it um Yeah, when I look at the home app I think My apple tv is part of the club my uh Home pod minis are part of the club, but that's really it So you could use home bridge to join all of your smart things devices to the club And and it doesn't preclude you from using your smart things devices the way you currently do It just adds that convenience layer of putting everything together In that one interface that's that that's accessible on all of your max and in control center and like all that stuff So like I do recommend doing the home bridge thing It if if you have a blend of home kit and non home kit devices because when it works Home kit is super convenient. Uh, it's just that you know, we're talking about maybe 60 of the time All right, take us to uh, take us to listen to john. We've got a couple of apple watch things to talk through. Yeah um John says I somehow developed a problem on my 24 inch iMac. I try to unlock with my apple watch and nothing happens It works fine on my macbook pro on the iMac I went to touch id and password and flipped the switch to enable apple watch But as soon as I do it flips back to off That's frustrating. Um, both devices are on the same apple id and as I said it works on my macbook pro Any idea of what is wrong and how to fix it Um I don't know. This is a rough one guys um I mean i've uh on my system. I've had the apple watch setting disabled But turning it back on worked. I never heard of it turning itself off again uh I mean a few thoughts one restart. I'm sure you've done that already, but you know can't hurt Um, make sure you have latest software updates. I seem to recall some of the recent ones had something to do with the watch Um, and the third thing maybe it's a cache. Isn't it always? Oh, that's a good idea. Yeah, maybe clean things up with onyx maintenance cleaning options I like that idea Yeah, I I mean, I've certainly seen this where when it says that it's on it doesn't work And and in those scenarios turn it off reboot turn it back on often Fixes it you've got to have your watch near you've got a pair And and maybe that's part of the issue here Like is the watch close enough is bluetooth on on the mac like it uses both bluetooth and wi-fi and I don't know probably the phase of the moon or something But it it yeah I like the idea of cleaning caches because if you can't get it to even attempt to turn on The rest is obviously an on starter. So yeah Huh Yeah Yeah, but mine I had turned off and I didn't realize I went into system settings and Typed in unlock and it came up with the ability to go right to you know allow your app watch to unlock your mac So I turned it on it came right on so I don't know what uh I've just been using the fingerprint ID, you know, that's On your on your a laptop. Yeah laptop. Yeah, it just seems that's it because when I need to turn it on I'm already touching the keyboard anyway. So it's right there and comes right on Yeah, and I don't know I'm assuming that capability has stayed with all the latest generation laptops Yes. Oh, yeah. Yeah, that's that's a that's a yeah, that's a so the need to turn it on with your apple watch is almost Less secure because you could be in the next room and someone could you know open your machine and turn it You'll get a little notification on your watch that how how often have you learned to ignore that? Oh, I'm I'm real good at ignoring that Yeah, yeah Yeah, I I noticed, you know lately I have been wearing my apple watches less Uh, or my apple why I guess I have to I'm my og one and I have the you know the serious five I've been wearing them less Simply because I've been enjoying wearing my you know my mechanical watches. I I love my mechanical watches. Um and I have noticed Two things like first of all where I really miss it Most regularly is my iMac in the office doesn't unlock anymore. I have to type my password fine. Okay Uh, but whatever like that's fine. I wish my phone could be that Like if my phone's in close proximity and unlock couldn't it unlock my mac like wouldn't that be an interesting way to do Anyway, um, I digress the other thing that I've noticed to your point Pete is phantom taps on my wrist I will be wearing a mechanical watch that does not have haptic capabilities And I will look at my wrist because I am certain I got a notification And I am wrong. So the yeah, uh, that's that's a real phenomena too. I read about it years ago about Uh, people feel the phone vibrating in their pocket. Yeah that too. Yeah, I don't notice that as much anymore But I have yeah Yeah, yeah Crazy. All right Let's stay with apple watch here and see maybe this is a little bit of a geek challenge But john you might have an answer for for mr. Mike here Uh, all right. Well, we'll see um Mike says I'm thinking of dumping at&t for cricket But the ladder doesn't have a cellular watch plan. Can I keep my watch on at&t and switch My phone plan to cricket Um Well, I only have a wi-fi watch so I I couldn't test this myself But um, they have an article calling setup mobile on apple watch and it's kind of confusing, Dave Okay, Pete. Um So they have one section and it says your iphone and apple watch must use the same network provider Okay, that's one statement. That's clear Um, unless the watch was set up for a family member who doesn't have an iphone If you change network providers on your iphone, you need to remove the previous service plan on your apple watch and sign up for a new plan Okay, so the way I read that is you got to reset up your carrier access on the watch Yeah so I wonder I would love to hear from somebody who's tried this right because I think I think that little clause in the middle there is separate from the others, right? Because if we take that out the The but You know if we say your iphone and apple watch must use the same network provider If you change network providers on your iphone You need to remove the previous service plan on your apple watch and sign up for a new plan Okay, like that makes sense This this little clause of unless the watch was set up for a family member who doesn't have an iphone I think lives on an island. I don't think it's related to the rest of those two statements uh However, you might be on to something here like If I have an iphone on mint mobile which mint at least at the moment doesn't have Uh an apple watch plan. I don't think unless it changed this morning or something. I'm not aware but Uh, let's presume I would I can't add my apple watch to the plan like you john I don't have a cellular apple watch. So this is a non issue for me But we'll go with this right so I can't have my apple watch to the plan And because I use mint on my iphone my presumption was There was no world where I could get an apple watch and put it on say at&t or you know one of the the you know Blessed carriers that can talk to apple watch However, what if I treat my apple watch like it is a family Uh member You know owned by a family member who doesn't have an iphone And attach it to at&t My guess is what that would mean is I would have to have it on a different apple id And it couldn't be on my apple id. This is a guess But my presumption is that as soon as The watch sees that it is connected to my Main apple id the one that was also connected to my phone. It's gonna say. Oh, no, no, no These have to be the same I could be wrong about that But my I would not surprise me if that if it needs to be a completely separate thing So that that watch and that phone don't share notifications. They don't share any of that stuff They're just you know, one is they're both members of the same family plan and that's the extent of their Relationship for lack of a better term But I don't know I I'm I'm guessing at this but I'm I'm get I'm I I wouldn't be surprised Can you even have an apple watch independent of an iphone? I don't even remember Well, that that's what they're saying pete is yes If you don't have an iphone If you're part of a family plan your family member can set up your apple watch without You having an iphone and therefore it can be on A carrier separate from your non-existent iphone But I think that's the the key point is your non-existent iphone as soon as you have an iphone Now they need to be on the same plan That would be my guess but I like this little geek challenge and there's a loophole here There's a loophole in the language. The question is is there the same technical loophole and my guess is no Because otherwise we'd hear about people doing this all the time But maybe it's just something we haven't heard about Great. Yep. Kurt Kurt noticed something Kurt says I have a 2021 m1 iMac with eight gigs of ram running monoray still and says oh, this is interesting This this actually well now it's possible that this My theory holds He says I open a lot of windows between browsers and office products when I first got the mac with all the programs running I would get the message saying I was using most of my memory and running out of memory Recently the memory issue or at least the alert does not happen. Did apple fix something? so You might remember if you've listened to this show for more than about six weeks That there was a period of time where we were talking a lot about All of these memory alerts that we were getting on our max and what you know out of memory alert What does it mean? Do I need to pay attention to it? How do I pay attention to it? What do I do to fix it? What do I do? Is it anything or is it nothing? and We had a lot of speculation there were certain things that you look at and okay, you're running out of swap space You're you know doing this. Okay. That's bad. This is bad. But these sort of generic non specific memory errors did exist and a lot of the sort of conjecture and conclusions that we came to was Eh, it doesn't seem to be anything to do Just ignore it and now We stopped hearing about all of those messages and curt noticed this So i'm wondering if curt's right. Did apple fix it? There have been updates to monoray, you know security updates But apple has been known to bake some things into these updates that go beyond security, especially nuisance fixes So did they remedy this problem? Or did they just simply Rerealign the alert threshold so that it wasn't so annoying because if we were hearing about it regularly here I also know who else was hearing about it a lot more frequently, right, you know So like I really I wonder if that threshold was just like somebody said all right If we're not going to be specific about this and tell users what they need to do How to to fix it then we can't be getting these phone calls And so it just raised the tolerance level. I don't know. I again more conjecture I don't know where they fixed it outright. Or did they fix it? Right? Who knows? Who knows? You know If they fix that I've got a list of things I'd like to have them take a look at now that uh, that's off their list because Especially in ventura like say core audio and ventura. I'm just Is there a problem with core audio and ventura pete? I you know what here Dave? I got a suggestion We can find out okay upgrade your podcasting machine to ventura and see if that works. Okay. Okay. Oh, wait a minute You tried a minute already wait. This sounds very familiar It sounds like you tried that and it was a total disaster. It was a total disaster Speaking of avoiding disaster pete You got a cool stuff found for us my friend today Um, I I do hang on hang on. Okay. Yeah. Okay. So I had to find out which one which one we were talking about um So in in my regular updates for security I got a warning that came across my desk Last week and it said the fbi warns against using the phone charging stations that scammers are using to attack your phone So when traveling, you know, we drain our batteries on devices most airports hotels Public places have free charging areas and usb ports, you know, like under the seats in the waiting area that sort of thing Yep Beware. All right There's a thing called juice checking and you should avoid using free charging stations at airports hotels Shopping centers that sort of thing and here's how it works a scammer puts a malware Or a monitoring software into a public usb port and that gives them the ability to steal data off of your phone Or even lock your phone up, you know, it could take passwords addresses banking information all that you you know How you have your entire life on that little thing in your pocket? They can get to it What can you do you ask to stop such a thing?  Yeah juice jack defender and I found one on amazon for for less than six dollars And essentially what it is it's a little usb a to usb a Plug like a pass through device. Yeah pass through device and what it boils down to is it Doesn't have any wires inside it that allow data to transfer only power Ah So you can still charge your device, but there's no route in there by which data can pass in order to Take data off your phone or to put a virus or data onto your phone. That sort of thing. So Right there if you're traveling a lot highly recommend that if you don't carry a battery pack Something to recharge yourself Then then have one of these little devices for less than five less than six bucks Plugged into the end of your charging cord for public use and never Grab a Look, there's a cord Right, right, right. Yeah. Well, let me just use that g. What could go wrong, right? Yeah, they can put data on there there is a there is A safety mechanism in the iphone where you have to allow the device that you plugged into trust this device To trust this device screen. Thank you. Yeah, exactly But let's say you you grab a cord that you just found and you plug it into your computer to charge It's gonna say trust this device. Well, yeah, it's my computer. Of course. Yeah, that's fair And there's no telling that there isn't something in there. Yep. Um, that's how You know that the iranian centrifuges were yeah, no, you're right. Yeah years ago. Yep Cool. All right. Well on the uh charging front john you had a cool stuff found to share with us for today Yeah, yeah, so um I got this for my birthday because I put it on my wishlist, Dave. Nice. Um What do you do if you're out and about and you need to charge your apple watch, but there's no charging station anywhere Well, maybe you should get this device that I found called portable charger for apple watch And it's a little battery pack 1000 milliamp hours. So you will get a couple of charges at least Um That's really it. Yeah. Yeah, what how much is it? It's like 15 bucks. There you go. Yeah good option For uh, when you're on the road, you need to charge. So for the listeners that can't see what we're looking at It's basically the size of a keychain. Yes Mm-hmm. Yeah little key fob That is awesome. The one thing I will share about this is it has a battery in it Which means if you're flying on a plane it needs to stay in your carry-on You can't just put it in your charger bag as a spare and and forget about it because you can't put batteries In a checked bag. How so unless you could disable it turn it off. Yeah, right, right Yeah, that's a whole another thing There is for 12 dollars a two pack Of these little things that I carry and I have I always keep one of them Actually, I keep one in my travel like my carry-on and I also have one in my charger bag Because for 12 bucks, they're cheap and it is just a usba to apple watch puck Similarly a little keychain thing. I keep a spare of these all the time. I have one in my car It is super handy to have these around And uh, and I've even been known to just give them away if if you come up to me and ask Do you have an apple watch charger? I can borrow. It's like nope. I have one you can have here you go Because they're 12 bucks. So now now I now I just I'm gonna put myself in the poor house because everybody's gonna come up Hey, everybody will be at Dave's after the show. That's right. Yeah Speaking of what you would see at Dave's after the show. I uh, I've I've been you know, I you know me I I like my nases my network storage devices and I like them to be able to run As hardware transcoding for my media library for my plex library and all of that stuff and synology Up until very recently was not including hardware transcoding engines in their devices and so I started looking elsewhere talked about qnap and qnap Has some devices certainly has some devices that are very much built for transcoding I found another brand though called terra master and I've been I got one of their terra master f4 423 It's a four bay nas. It's got a cellar on chip in it for which has Transcoding it's a it's the cellar on n 50 95. So it's a quad core And it'll do you know 4k transcoding it I've been testing it for a while. It's fantastic I like it's web-based user interface Much better than uh, the qnap interface It's it's actually very similar to the synology web interface. The one thing I will say it is Dollar for dollar less expensive than the qnap For you know features for per dollar However, and so compared to if you want just something that's going to do hardware transcoding And you don't want to wait for you know, the perfect synology new model to appear that would do it This is a good option to look at the issue Is that synology Has way more features In terms of its apps than terra master or qnap have neither of them has And an analog to the synology office suite, which I find to be spectacular I love being able to use synology office.  It's awesome. That doesn't exist on terra master But if you're looking for a a nap they do have cloud syncing So you can run your own, you know private net private cloud Just like your own private dropbox terra master has that they have native apps for mac and iphone and ipad as well as you know windows and and such and android And you know, it's a it's a solid nas offering and I like what they're doing. It's pretty cool How's your price point Dave? Um, you know the one that I have with this celeron in it bear is 499 So that's you know, that's that's about 150 bucks less than you'd spend on a synology It's about the same price you'd spend on a qnap. So um, so yeah, I've been I've been uh I've been happy with it. You know, it's a it's a it's like I said, it's a solid offering So that's uh, that's where we go Always good to see competition and things like that because it keeps us the other prices down Well, and it keeps like the feature set is sort of the important thing like the fact that this exists The fact that qnap is doing what they're doing the fact that we've been saying what we've been saying and I I will I will reiterate that You know, our community's voice has been no small part Of why Synology took a second look at transcoding on what they're doing the marius hosting's community Similar, right? Like we we definitely, you know joined Joined a similar mission with marius on this and and and he joined with us. So it it's But you know like it's good to have these things out there so that you can see what the options are And compare and contrast. Yeah, it's good. The competition is great. I agree That's what we got time for today folks. Thanks for hanging out with us. Sounds like the band is playing the band's playing man Champing at the bit as it were Yeah We chomp at the bit We chomp at the bits we champ the horse champs at the bit, but do we Here on the show what is what we're doing like chomping at the bits or are we chomping and spitting the bits And then you get the bits and your You your computer your iphone takes the bits and transforms them back into an analog signal that goes into your ear holes And then that's what we did here. I don't know. It's something about the bits All right, uh That's what we got you got anything else to share john No Thanks for hanging out with us.
