Hey everyone, can you see the shared screen of the assignment for questions? Right. And you can hear me find there are no issues with the audio. Perfect. Okay. We can get started then. So welcome to this week's recitation. I'm going to walk through assignment for and also some general comments on what I've been seeing on the discussions on Piazza. And after that, you can ask all the questions on the chat if you have anything. Okay. So this assignment is about Web of Trust, which is basically about you building a network of people whom you can trust. And we do this using public key cryptography and GPG to verify each other's identities and build your web. Okay. So your first step is you have to create a GPG key. There's really good guide already here that you can take a look at. There are lots of tools that you can use to create GPG keys. You can use a command line tool called GPG. There are also several UI programs that you can use. Some names were mentioned in Piazza like Cleopatra. There are also many other tools are available for whichever platform you are using. Feel free to pick any of them and use it. Most of those tools also have reasonably good documentation. So it shouldn't be very difficult for you to generate the key. The most important thing that you have to remember when you're generating the key is that the name on the key has to match what is there in ASU system. You can use any email address. It doesn't matter, but there should not be a comment. The conditions on the name and the comment is an absolute requirement because that is what we use when we have validating your submission at the end of the assignment. Another important reason also is that you have to get your key signed by other students and they might rely on your name in order to validate your key and then sign it. Another very important thing is after you generate your key pair, please do not lose it. Back it up somewhere. It's very, very important because we will not sign multiple keys for you when you submit on Gradescope. And if you end up losing your private key, you will no longer be able to sign anybody else's keys and then we will not be able to score you correctly. So if you ever want, please do not lose your key. It's very, very important. If you are concerned about using an existing key that you already have, I would recommend that you just generate a key because it's not good practice to put your private key somewhere where you want to back it up. I definitely recommend generating a new key just for this assignment, but feel free to also use an existing key if you want to. So once you have generated your key, just like in the crypto assignment where you had to submit an empty file and then you actually get the ciphertext. Here you actually submit the public key that you generated onto Gradescope in the assignments named web of trust upload. And when you do the upload, the Gradescope grader is going to check if your key is valid and it's going to send you back the public key except that we also signed the public key that we just uploaded with our own private key. Now, after you get the signed key from Gradescope, it's highly recommended that you verify the signature using the public key that we are using for this course. You can download the public key from this URL here, which is there on the webpage with the assignment for description. In order to verify the public key, we're also giving you the fingerprint before you, in order to ensure that the key that you downloaded is good. In addition to also giving you the signed public key, we also give you an adversarial keeper, both a public key and a private key with the same email as your key, but with a different name. This is going to be used for a later part in the assignment. So we'll get to what the adversarial key is given to you later in this recitation. Once you've received your signed public key from Gradescope, you need to get your public key signed by at least 30 other students in the class. There are two really good manuals here on how you actually do the signing. The key challenge in this assignment, in this part of the assignment, of course, is you must verify that the signatures are from a valid key for this class. It's up to you to ensure that the signatures that you receive are actually generated by a key that's valid for the class. It's signed by something else not used in the class and not blacked by the Gradescope system. You will end up in that signature would not be counted towards your total 30. Please be sure to verify that you're getting signatures from valid public keys for the class. Right. So the signing is actually how you build your web of trust. When you actually certify someone else's public key using your signature generated by your private key, you're essentially certifying that the other person's public key can be trusted. And that's how you build your whole web. So please be sure to verify that the signatures are right. And you should also ensure that you actually sign valid keys. That's the next part of the assignment. You also need to sign at least 30 public keys of other students in the class. Right. We should also make sure that you do the signature properly. There are a couple of people who have been having issues importing the signature. We also have a discussion in there. I'll talk about it later in the recitation, but please be sure that you sign correctly. If you have any doubts, you can just make sure that you talk to other people who you sign make sure that your signatures are fine and makes also that the signature is coming from them are also done properly. Also be very careful on which keys you sign because if you sign in valid keys, you're also going to end up losing points. So if you don't sign any invalid keys, you will receive a whole score of 10 points. But depending on how many invalid keys you signed, the amount of points that you lose would vary. This is to illustrate that trust is an important part of the web of trust who should absolutely only trust a public key if you're sure it's valid and belongs to that person. If you were to randomly certify someone as owning a public key, that is going to break the fundamental trust in the whole web of trust and makes the whole web of trust not very trustworthy. Right. On the flip side though, if you get other people to sign your adversarial key that was generated to you from great scope with a different name but the same email as the key you uploaded, you can actually get extra credit for taking people into signing the adversarial public key that they should not have done. Right. So they're tricky. I've already seen that a lot of people are trying multiple ways to do it. So please be careful which key you sign. Make sure you validate it as a good key and not an adversarial key so that you will not end up losing any points. And finally, once you have collected 30 signatures and if you got any signatures for your adversarial key, you need to submit all these files that are listed here on the submission server along with the read me that's going to have your name, your SUID and what do you think about GBG and key signing here and also a description of how you manage to get other people to sign your adversarial key. The submission server is currently not open right now. Please check back in a few days here. Adam would add the link here and if you don't hear back from us very soon, feel free to put a post on Piazza and one of us will get back to you on it. So that's the description of the assignment. I see there's a question that I will come back to it. I'm just going to give you a couple of other points that I'm seeing based on the discussions on Piazza. One of the important challenges that a lot of people have been having is how do you verify the signature that's generated from great scope using the courses keep it right.  So I'm not going to give you the exact command. But in general, what you would have to do is first import the courses public key that's linked to from part two of assignment for here. Verify the fingerprint on that public key and then use the GPG command or if you're using a UI, whatever UI mechanism is there for you to verify that the course course key has the fingerprint that's mentioned here. And then you can be sure that the course public key that you have downloaded is correct and then just on the verification command and it'll tell you whether it's correct. So you find the courses public key again, repeating it you find the courses public key on the part two of assignment for page on Adams website. Please download it from there and verify the signature that you get from great scope. Another important problem that a lot of people have been facing is the whole cross platform issue where you just ask GPG to display the output on the standard output and then you redirect it to a file which is going to mess up if you were to send that file to someone else using a different platform. For instance, maybe you sign someone who's using a Mac and then you sign their key on Windows and you send it to them and they're not able to verify your signature that you gave them. So rather than using redirection, please use the dash dash output flag that's there for GPG. If you're using a UI it must be possible to say ask it to save the signature or any output from there into a specific file. So please do that do not do redirection that is going to mess up a lot of things if you start going across operating systems. The other important thing is that you should share the signed public key that you get from great scope and not the public key file that you generated before you upload it to great scope because the file that you get from great scope is signed using the courses there and if someone else were to check your key, they would not be able to verify if your key was signed. So when you ask someone else to sign your key, be sure to give them something signed from great scope and not without the course signature. The last thing that I wanted to point out is a couple of people are asking, now what if I get a signed public key from someone else? Does it mean that I need to go re-sign all the keys that I signed because I have a new signature from another person? The signature is conceptually different from the key, regardless of how many extra signatures you keep tacking on. Any signature that you created before you received any new signatures is not going to change. The signature is basically someone else certifying that your key is correct. It does not affect any signatures that you create using your keys. So you don't have to worry about it. You don't have to do anything. And in addition, GPG can also import new information like if you get three new signatures, GPG is smart enough to figure out that this is a public key that I already know and here are some new signatures for this public key. I'm just going to add them together in my internal database. So you don't have to worry about any of that. GPG would make sure everything is working fine. So that's some of the things that I wanted to point out based on the discussions that I saw on Piazza. So we already have a question here. How do we verify validity? Could you please elaborate a bit more, verify the validity of what exactly, it's not very clear to me what you're trying to validate. You can just post it on the chat. That's good enough. I mean, well, if anybody else has any questions, please feel free to post it on the chat and. So we do have a new question here, but I'm just going to quickly address the follow up to the previous question that I was answering. To the person that's clarified the question being asked is how do we verify if a key is valid or adversarial. I'm not going to answer that because that's part of the assignment. Okay. It's not very tricky. You can figure it out, but not going to tell you how to do it. Okay. So the next question that we have is, so do you lose points if you sign? So do you only lose points if you sign adversarial keys? What if you sign an invalid key that is not adversarial? Like if someone messed up the name spelling in their key, hadn't submitted it to Grayscope yet, and you still signed the key with a misspelled name, would you lose points? So you wouldn't lose points for part five where you need to sign invalid keys, but you probably would not get points for when you need to sign other people's public key. But regardless, I would say be very careful on which keys you sign. If you have any kind of doubt that this is not a valid key that you should sign, I would recommend that you don't sign. I would say don't risk it. That's the whole point of the web of trust. You don't want any sort of chances. You want, when you make a signature, you want to be certain that this is the key that belongs to that specific person. There should be no room for doubt anywhere. So I would err on the side of caution and not sign a key if you don't trust it. I hope that answers the question. If it doesn't, please post a follow-up. I'll be happy to clarify. If anybody else has any questions, feel free to post it on the tab. So the question here, just to clarify, importing a key is not the same as signing the key. That is correct. Importing a key is not the same operation as signing a key. Importing just means that you're just adding the key to your GPG database in your machine, where assigning is when you actually certify that the key is trustworthy and that is done using your private key. So they are not the same. Importing is perfectly safe to do. Feel free to import as many keys as you want, but be very careful on which keys you sign. And also, if you want to verify the signature created by another student in the class, you would need their public key to verify. I hope that answers the question. If anybody has any questions or any follow-up, please feel free to post it on the tab. So we have another question here. Do you have a recommendation for how to find people to share keys with? I've been doing it on Gradescope. Sorry, I think the person meant, I've been doing it on Piazza, but it feels like it takes forever. No specific recommendation, sorry. No specific recommendation really, how you can find people to get them to sign a key. A lot of people have been finding people to sign their key on Piazza. They create signing threads where they just post their keys and ask if someone else can sign their key. You could write that, but I think a lot of people have already hit 30 signatures and so probably they might not reply because they don't necessarily need more signatures. But Piazza is definitely one way to get signatures. The other problem, of course, is they've been not meeting in person anymore during the lecture or anything, so it's very difficult to get signatures from there. Feel free to reach out to other students through multiple ways. You can maybe find their profile, contact them outside of Piazza, maybe shoot them an email if you find their profile of some kind from ASU's website and ask them if they could sign. There may be other communication channels. There are a couple of communication channels discussed on Piazza, but I'm a little hesitant to also recommend them because you need to be careful. We don't control it, so if you accidentally sign someone's adversarial key, that's on you and not on us. Feel free to reach out. Usually in the real world, a lot of this is done in person, but since we don't meet people directly, it's a little tricky, but if you have some time, you have multiple ways of reaching out, I think you'll be able to figure it out. Also something just to add, even though a lot of people are not necessarily replying right now, there could still be people who would be interested in receiving more signatures and also giving out signatures because it's recommended that you get signatures from more than exactly 30 people to ensure that there are no problems and someone claims to have signed yours, but then didn't sign yours or something went wrong in the whole signing process, etc. So I would also recommend, don't aim for just 30 signatures. Try to be safe and get a lot of signatures so that there would be at least 30 of them valid in the big set of signatures you received. So we have another question here. If the person doesn't have the CSC 365 S20 key in their hearing, is it best not to sign their key? I'm not really sure if I understood your question correctly because my understanding of a key ring is the local GBG database that I maintain. I'm not sure how you can check if someone else has imported the CSC 365 S20 course key into their local key ring because you probably don't have access to their key ring. Okay, we have clarification from someone else. They probably meant if it hasn't been signed by their, by the course key. I'm also going to err on the side of caution and not answer that question. Yeah, sorry. Use your best judgment. Decide if you want to take the chance. It's fully on you. I'm definitely not going to make a recommendation for that. So we have another question here. Did you say that the grade scope submission will be up soon? Yes, I believe that the submission service will be up soon. I'm just not sure if it's going to be on grade scope or if it's going to be somewhere external. I would say just wait it out a bit. Collect your signatures. Don't necessarily wait until the submission server comes up because the submission is independent from you getting everybody's signature and writing all the read me and stuff. But yes, it should be up soon. We probably wouldn't take it too close to the deadline, but it's computers. There's no guarantee. But we will try to get it up as soon as possible and give you enough time before the deadline so you can still submit troubleshoot if there are any issues. Sorry, I don't have a more specific and better answer. We would likely also announce on Piazza. So keep monitoring the discussions there to see if you see announcements from one of the TAS or from Adam. So we have another question here. If someone gets people to sign their adversarial key by changing the name or the UID on the adversarial key and stripping out the course signature. Does that count? I am not certain if the adversarial key that you get from grade scope is signed with the course signature. I haven't checked. So that's why I'm not sure. We have clarification. Thank you. It is signed by the course key. But yes, if you still get someone to sign your adversarial key without the course signature as long as the signature on the key is valid and you can verify the signature. Then using GPG, then we would also be able to verify the signature on the adversarial key that would count. Like I said earlier in the recitation, the signature is different from the key. The signature is just a certification stating that the key can be trusted. It's not really associated with the key. So yes, if you do still get the key signed. Even if it doesn't have any additional signatures along with it and you can verify the signature locally using GPG, it should be good enough. That's what I would say. I hope that answers the question.

The Prime Minister and the BJP said that the Congress Party has done nothing in 70 years. There is a list here of all the assets that the Congress Party has helped build. These assets have been built using public money. Thousands and thousands of crores of rupees over the last 70 years. Now the Prime Minister is in the process of selling the crown jewels of this country. I am going to read what is being sold and you can guess to which monopolist it is being sold. Frankly this entire list is going to go to only three or four people. And these are the sectors that those three or four people are interested in. So, roads 1.6 lakh crores, 26,700 kilometers of national highways, railways 1.5 lakh crores, 400 stations, 150 trains, railway tracks and woodsheds, power transmission 42,300 circuit kilometers of transmission network, power generation 40,000 crores, 6,000 megawatts of hydro solar wind assets. Natural gas pipeline 25,000 crores, 8,000 kilometers of gale pipeline, petrol pipeline 4,000 kilometers, Indian oil and HPCL pipelines. 22,000 crores, telecom 35,000 crores, 2.86 lakh kilometers of Bharat net fiber optics, warehousing 29,000 crores, 210 lakh metric tons of food storage. Who is this designed to hurt? This is designed to hurt our farmers. This is designed to make sure that one person gets a monopoly in the agricultural system of India. Mining 20,000 crores, 160 coal mines, airports 21,000 crores, 25 airports. You know who the airports are going to, who they have been going to, these 25 will also go there. Ports, 13,000 crores, 31 projects, 9 ports, you know who that is going to go to. Stadiums, 11,000 crores, 2 national stadiums. So, this is what is being given away, what is being gifted. There is an excuse they have come up with that we are leasing this. Let us suppose you give 25 airports and you are helping create a monopoly of one person owning all the airports. Fine, 40 years later we have a discussion but by that time the game is over. So, it is not a question of whether it is being sold or it is partially sold, it is a question of control. You are giving them full control for 40 years to do whatever they want. You think 26,700 kilometers of national highway is languishing in this country? Where? There is not a single national highway that is languishing, go anywhere, it is full. Road sector is not languishing, railway sector is not languishing, power transmission sector is not languishing, mining sector is not languishing, telecom sector is not languishing, warehousing is not languishing. So, what is she talking about? Which sector here is languishing? Even stadiums are not languishing. So, now you are telling me that roads are not being utilized? That by giving it to private person the road will suddenly start getting utilized? It is getting utilized right now. You are telling me railway trains in India are not getting utilized? You are telling me power generation, natural gas pipelines are not getting utilized? Thousands and thousands and thousands and thousands of crores have been put into that to create that asset. Now you are going to take a little bit of rent from that asset and you are going to give the asset to these people and what is going to happen after 40 years? Who knows? Who knows what is going to happen after 40 years? Now, the government clearly has mishandled the economy. The government clearly does not know what to do. They have basically destroyed what the UPA built. And now as a last resort they are selling everything that we had helped create. We have dealt earlier with a monopoly in India. It used to be called the East India Company. It enslaved this country. It was basically a monopoly. That is what is happening now. We are heading into enslavement. So that is something that has to be understood. Demonetization, GST, the way they designed it, is designed to do two things. Number one, it is designed to kill the informal sector. Destroy the informal sector because an informal sector person, if you do demonetization, he doesn't have the cash flow to save his business. His business dies. You can go and ask any small person, small businessman that if you give him a shock like demonetization, he can't survive. And GST as it is designed today is essentially a tax on small and medium businesses. It is targeted to hurt them by making them formalize themselves at tremendous cost. Whereas a large company has no problem. A large company can hire 5 or 10 accountants and say, you know, we'll fill GST, but that individual shopkeeper or mithaiwala or person who is running a small shop, he doesn't have the infrastructure to get those accountants. So he just dies. So those two ideas were to destroy the informal sector. The three farm laws are to destroy the informal sector in agriculture and to ensure that monopolists can come into that sector. Mr. Modi believes that large monopolists can transform this country. He does not realize that when you create such large monopolies, you cannot give jobs to people. And when you cannot give jobs to people, it leads to social tension, social anger and then social explosion. So you will see a dramatic increase in violence. You will see a dramatic increase in anger. You will see millions of youngsters who simply cannot have a future and they will look at the houses of these monopolists and they will wonder what went wrong with India. That's what is happening. Mr. Modi is not the Prime Minister. He is an instrument. He is doing a particular job for these people.


My name is Richard De Palma. I teach here at Harold S. Vincent High School. I teach chemistry, biology, and greenhouse techniques. STEM is an amalgam of science, technology, engineering, and mathematics, and probably going to be the necessity for the future in sustainability with respect to natural resources and energy consumption. Science, technology, engineering, and mathematics are the amalgam that we'll need to produce the sustainability that the future of this planet is going to have to have. My name is Will Allen. I'm a farmer and the founder and CEO of Growing Power. This is a very science-based kind of learning, working on a farm. They might come here at first, and they don't understand it. They might think that they don't like it, but after they get involved, they really become passionate about it. I think our students are, this next generation is going to be very important in terms of making that happen. Because for kids to learn about their food system, they have to do it in a very hands-on way that leads to, I believe, academic excellence. But we must pass on and make it possible for them to learn about the food system. And right now, not in all of our schools, are we teaching young people about our food system and how important it is to them. But we need to start doing that. I'd say about 20% to 25% of the students are getting it. They're finding out that what's going on here is what's going to be going on in the future. It's fascinating to see the students generate ideas and then to be able to put an idea together and then test it. I'm a junior at Benson High School, and I am studying greenhouse techniques. I like science because it helps me learn more about my environment and what's around me. I never really got to work with fish or plants, and I'm learning new things about them every day. I like science and math because it's different. It shows me something new every day. The fish, they don't like to stay still. They're hopping all around. And you've got to keep focused and make sure you get all the right measurements in the length of the fish. Hands-on learning is different from using a book because you're actually doing it yourself as that arena, and you actually have more fun with it.


Hey, everyone. What's up? It's Rob. Welcome back to day two of Polymer Summit. I am joined right now with Monica Dinkalescu. Monica is emceeing day two of Polymer Summit right now. On top of that, you also gave a talk yesterday on the importance of being lazy. For anybody who hasn't seen your talk yet, can you summarize what you mean by that, why it's important for developers to be so lazy? Yeah. I think one of the things that I don't enjoy doing is reinventing a lot of wheels. I try to be the laziest developer possible. I try to use things that other people have built. In particular with Polymer, I try to use other people's elements. If you build something that authenticates me or gives me a nice fast list, I'm going to use that and not do extra work that I don't have to. Yeah. One of the things that you mentioned was, you were kind of freaked out about doing authentication, which is like a legit fear. I got that same fear. In your talk, you talked about using Firebase to do that, and how it kind of streamlined that for you. In a nutshell, how did Firebase make that easier for you? Firebase is really awesome because you can create a project on the Firebase console, but then Chris on our team and Elliot and a bunch of people have written these amazing Polymer fire elements, which are Polymer elements that work with Firebase. So you can declaratively connect to Firebase, and there's one element that lets you authenticate magically, and it's basically you put an element on a page and you call that thing.login, and that's it. That's how you sign in. Right on. Now, for folks who haven't seen your talk yet, but are about to go watch your talk, and if you can have them do one thing, what would that one thing be? OMG. You should go to mojibrag.firebaseapp.com, which is this dumb social network that I built for this talk, where basically everything you type gets translated to emoji, and everybody just writes emoji at each other, and it serves no purpose at all. So go check it out. But it's internationalized, and translate things for me. If you speak any languages that you don't see in the dropdown, make sure you send me a PR. That's right, right. PRs, not issues, folks. Okay. So, Monica, thank you so much for being with us.  Get out of here. Yeah. You out there, keep watching on the live stream. I'm Rob, reporting live from Palmer Summit. Stay with us. Bye.


We got an exclusive from Aptara answering viewer questions. This was a viewer comment that I received on a recent Aptara video. Specific questions and concerns were mentioned. I promised a response to the submitter. I sent it to Aptara. They delivered fast. This video, not so fast. Sorry. It took me a while to get this together. Cover the main topics brought up here from the viewer email. This is direct from Media Relations or Aptara corporate. Here we go. Let's start with the first question. This is the actual text that was on the response on the video. This is AG, we're going to call them. I was going to post this to this video. You're just going to have to watch this general video to get your response. He asked a number of different questions and made some points here. First one is, use your discount link, went to their site and it was still $100. Let me start by saying I have a discount link. This is the answer from Aptara. Everyone, there is a referral link in the description of this video. It's very easy to use. You click on it, I have tested it and we have this backup from Aptara. It does work. Let me just go through the particulars here. Use the link and receive 30% off their pre-ordered deposit of $100. Which is refundable. If you want to put a pre-order in for Aptara, use the link and there is a $100 deposit. If you use the link, you will get a $30 discount and it will only be a $70 deposit.  In any case, use the link after the person you refer selects their vehicle configuration. Select the battery type, color and so forth. Any additional upgrades for the pre-order, they will be directed to the checkout page. When you configure it, it's going to say $100 deposit. In other words, when it's in the shopping cart, it's going to say $100 deposit. Only when you proceed to the next step at checkout, will the $30 deposit discount towards the pre-order be applied. When payment details are requested. It appears as though you're not getting the discount or that the link doesn't work. The link does work. You do get the discount. You have to proceed to the checkout when payment details are requested. The $30 discount will be applied. So it's at the end of the process, not the beginning of the process where the discount is applied. Just a side note from them here. If you try to reserve a vehicle through a referral link, the website will read $100 until you reach the checkout page. As long as it's in the cart, it's going to say $100 when you get to the checkout page, the 30% discount is applied. This is called some confusion. They say they're unsure of an easy fix at this time. This referral program has been up for quite a while. There's been a lot of referrals, I'm sure. They don't want to mess up the past referrals and so on and so forth. Anyway, let's just go to the summary on this. On the referral program, it works. You just have to get to the checkout page to have the $30 discount applied. Once they ask for payment information, it'll be discounted from $100 to $70. Aptare knows you're confused. It does not appear immediately and they're working on it. In other words, when you configure it, it's going to say deposit to $100. When you get to checkout, when you apply the payment method, the $30 discount will be applied. That's the way the system works. They know everybody's confused about it, but they're working on it. The link works. I have a link in this description. Please use the link to pre-order in Aptare. I believe there's about 18,000 orders right now. Their first year production is going to be about 10,000 estimated. Getting an order in now is going to ensure that you're going to probably be able to get near Aptare by 2023, perhaps. I hope that solves that problem. Moving on to the next question. Many customers, and this is Agent's second question, many customers will be from overseas. They do not offer any shipping cost information guidance. He goes on to comment it's unprofessional and so forth. Let's see what Aptare has to say about shipping cost in international sales. This is Aptare's response. We plan to sell Aptare worldwide. It's always been the intention. Though it may take some time to be fully certified. I'm going to try to put a link here, one of these little things up in the corner, to my previous video on homologation. That is what we're talking about here. And we'll go through this on the summary of this response. So they are planning that it's going to take some time to get certified. They're going to be announcing further details on the timeline, pricing and delivery information via your Aptare US account page. Closer to the start of initial US deliveries towards late 2022, which is Q4 2022, you will get an Aptare US account page when you order an Aptare and that's pretty easy to work with. And this is where they're going to announce the details on the shipping and international sales and so forth. Now I have a summary here. This is the shipping cost question. International sales are coming and again I'm going to try to put a link to my last video here, or it's certainly in the description about homologation. When they say that it's going to take some time to certify homologation is a term that's used in the auto industry, other industries too perhaps, where they have to meet certain requirements in every country they plan to sell the car to. Now the EU is considered I guess one country, but there are some minor differences in between the countries North America, Canada, South America, then you get into Asia. The point is this homologation process is a way of certifying the vehicle across all these geographic areas. And it's complex and there's a lot of detail that has to go into it. Every part has to be listed. Every part has to be certified. Every requirement for each and law has to be followed for each independent country. So it's complex. The Lord's time mother is just going through this right now and this is what's going to happen now. And it says details will be announced late 2022 on your APTERRA account page. You have an order there's going to be an account page 4th quarter 2022 we're going to announce it. Just let me say one thing about international sales. APTERRA is planning on using a dodge Viper model for manufacturing this vehicle designed by Sandy Monroe. This is a variable, this is a factory that can be upsized or downsized depending on demand. Now what they're going to do is they're going to have basically six components that are going to be supplied by APTERRA and by first tier suppliers to the automotive industry. These basically six components are going to be shipped to this factory and they're going to be assembled at this factory and the APTERRA is going to be built there and shipped out of there. Now these factories or these micro factories I guess you could call them are going to be placed where the highest demand is for the vehicle. If there's a lot of demand for APTERRA in the UK they're going to put one in the UK so this is going to be a factor with the shipping cost less. But those are the plans of APTERRA that's how it's going to work. Anyway international sales yes. Commodulation yes. Details late 2022 on your account page. Third question I think this is the third question. I have two down here. Now he's talking about using a key your phone as the key for the vehicle. He also has a question about whether the auto system is going to be Android auto and so forth. Let me just add in addition to this email response APTERRA has a lot of videos and webinars online on different aspects of the vehicle that go into great detail. I remember from the past viewings that there are a number of these videos about the auto system, the control system the operating system of the vehicle and so forth in its design and its ongoing. Now as far as the you can look up those videos that's a very good source for all this information on this to get an idea of what they're talking about. Now the main issue here is he's talking about doesn't want to use his phone as a key. What happens if it gets lost or damaged? Okay so let's see here. This is you're going to add facts on the website to the user interface system and the phone acting as a key so they're working on it. This is just a basic rundown of how it's going to work. The vehicle will recognize that as you try to open the door we have not made a final selection on this and they're going to use proximity detection to unlock the doors. Giving these either Bluetooth to be a smartphone, through an app through a proximity key like the Rivian has that little thing you can clip on your belt and carry around Tesla in addition to using your phone or an app they have a card that you touch on a spot on the car. These are all possibilities. They haven't finalized this design yet. I would imagine this has to do with a lot of things including supply chain. Once inside you can open the door through the center screen controls. So the driver side door will be open then the other one will open with the screen. The doors will have manual pull handle for emergency so there's going to be a manual overwrite as well. Okay this is very cool. When you're in the app terror it is on. There's no buttons to start. You just put it in gear and go. Very cool. The vehicle recognizes you and you don't have to fumble, you don't have to do anything, you don't have to enter any code. Boom. The vehicle will automatically lock itself when you leave. So we leave it automatically locks itself. It recognizes you're not inside. And there's going to be further information on this whole system once we have finalized the design. We have a solution in place which will allow access to the vehicle with a mobile device. I'll be able to provide final solution closer to the start of production. So I hope that gives you an idea. Let's just go through the summary response on this. Door will open when you approach. The method is not finalized yet but the cell phone will not be the only way this is going to be enabled. And once you get in the car, so you walk up, door will open get in, it will just run and then when you exit it will lock automatically. So this is a very cool system. Tesla has a similar system. I'm sure Rivian, I've not looked into it, has a very similar system. So no, the cell phone will not be the only means of entry. They are going to work on a fax page regarding this. And again there are a number of videos on different aspects of the car that will likely include comments on this. So that's the answer on the phone key. I hope that was clear. This is just a summary on the Aptara response. This was very quick and professional by Aptara. It took me some time to get this video together. I'm sorry about that. They covered the key points that this viewer asked well. There are some aspects generally, you know, not enough information and so forth, but the key points were covered very well by Aptara. They gave solid answers and honestly best response I've gotten so far from a company when I send questions in. They inspire confidence in my opinion I have down here. When they say they don't have something finished, they're not saying oh, we're going to do that and it's going to be great. They say hey, we're working on it. We're going to let you know when we're finished. This is how we're planning now. This is very transparent, a very kind of honest response. Then some background. I have a video on the founders. They have a very transparent, very honest appeal to their character as well and it's reflected in the company. So that's another big plus by Aptara. Overall I give it a star, a gold star. That should be gold, not gray. So Aptara I have down here, building a new vehicle from scratch and many systems are still being worked out and finalized. There was an Aptara before. The body design is based on this, on that Aptara because that is an optimal design. It has been tweaked and improved but you're going to understand this is the Aptara too. This is a completely new vehicle. Clean sheet from the ground up. Absolutely other than the shape, very little relationship to the prior Aptara. There's prototype, alpha, beta, and pre-production vehicle. They're now on the beta stage. The beta stage is going to work out all of these systems. It's going to be very close to production and that's the stage they're at. They haven't finalized the betas. They've built a few, they've built a number of them, but they're still working on it. We have to give them some time to do this. We have to have confidence in the design and engineering teams involved. I do. I think they're doing a great job. They've got Roush involved. They've got Sandy Monroe involved. These are some top tier players. That's where we are with the Aptara. We have to cut the Aptara some slack in my opinion. The response to the Aptara 2A based on my channel stats is exploding. There is growing interest in this vehicle. You can expect the website to run slower times and so forth. This vehicle as I said in my last video is the new VW Bug only better. The VW Bug was the most manufactured vehicle ever made and it still holds that record. Execution is everything and finance is everything, but certainly this vehicle has the potential to be a really big game changer and I think we've got to allow them to develop. This is MXUX.

5 Unusual Ways To Build Strong English Vocabulary. Vocabulary lessons are quite easy to teach and students love them because of the many exciting games teachers usually implement. In this article, we want to share several unusual ideas for building strong English vocabulary that will definitely help you in your classroom. 1. Play Doe Word Building. You can approach any age group with this activity a stirrer or always visual spatial types of learners. Plus, it is scientifically proven that the human brain creates strong connections between hands-on experiences and abstract concepts like words. So, if you want to help your students remember new words better, offer them spelling those words with Play Doe or Plasticine. You can also use watercolors, markers and any other materials for this activity. Make sure you choose vocabulary related to a particular topic or a linguistic point, like a common spelling pattern. 2. Greek and Latin word roots. This language point is extremely difficult to both ESL and EFL students. However, teaching root words is necessary for building wide-range vocabulary, practicing spelling and building strong reading and writing skills. Before actual teaching, explain what root words are. Root word, a special part that has a meaning but can't stand alone. For example, odd has a meaning to hear or listen. Together with a prefix or a suffix it makes a word related to listening, audio, audience, audible, etc. Compare root words with base words. Base word, it is a word itself. It can be used without any other additional parts and can be complete. If they are being paired with suffixes or prefixes, their meaning changes or modifies. For example, the word happy is a stand-alone word. If you add a prefix un, its meaning changes completely. Teach explicitly. Create an anchor chart for the root words you've selected. Use a picture, a definition, and a list of words containing the same root. Practice root words from the set regularly by playing a root of the day or week game. Evaluate your student's understanding of roots with other writing and reading activities. 3. Interactive word wall. A word wall is a set of words displayed in large visible letters on a surface in the classroom. A usual approach to creating a word wall is based on alphabetical order. However, for EFL and ESL learners it is better to use interactive word walls that focus on a specific topic or concept, and are supported by pictures and even real objects so that students could easier make connections between different words. Use word walls as a pre-reading routine and as a part of your vocabulary lessons to train spelling and writing. Possible activities can be chanting, clapping, tracing, word guessing games as well as writing and reading stories containing the words from the wall. To set your word wall, select a set of words, 5 per week would be enough, and place them on a board. Those who do the work, do the learning. So, encourage students to help you. 4. Labeling real objects. Again work on building connections. This is a great activity for older students as they can easily incorporate this activity into their everyday life, so give it as a part of their homework to label things in their house or office. With younger learners, make labels in your classroom. 5. Find a native speaking pen pals. This activity may be challenging for you as a person because you will need to find a teacher from a native speaking country and offer a language exchange. If you want your students to succeed in English, don't be afraid to make a post in our Facebook community, there are thousands of teachers from all over the world. Together you will be able to create dozens of fun activities that students will definitely love. Do you want to teach English abroad or online? Take a TEFL course. Have fun implementing these five activities in your vocabulary lessons. You can easily adjust all of them to online classes using these tools.


Tuesday, October 11th was National Coming Out Day, but Boston University's Center for Gender, Sexuality, and Activism has an entire week of pride planned.  Be proud of yourself and who you are and talk with other people who share your same identities and be able to bond over that and like, I don't know, connect with them. For many students, the CGSA events have provided that space and connection. I feel that the CGSA truly emphasizes not only just a safe space, but also provides opportunities for collaboration and also just an overall place for us just to come together and just have a good time. Like just having that community where you can celebrate yourself and celebrate other people is really important. Establishing a safe queer space on college campuses has proven increasingly important with one in five Gen Z now identifying as LGBTQ according to a 2022 ballot poll, and the average age to come out is 20. Coming out is a pivotal moment for a queer person, and having a day to honor that means everything.  As you can see, the CGSA is full of pride this week. For more information about their events, visit their Instagram and be sure to stop by 100 Bay State Road to check out What's in Store. For BUTV10, I'm Annie Main.
