Well, I'm prepared to be even more confused. Hahaha. Don't worry. I think this might be easier. Yeah, in the previous episode, we were talking about how cryptocurrency has no central authority or central regulatory bodies to really oversee it. For me, that just sounds like a problem waiting to happen, really sounds like troubles. Because definitely, some people are gonna use it for criminal activities, you know. Exactly. That's one of the things that a lot of people talk about cryptocurrency is the fact that it's connected to crime, which is - you can say that for just about any currency, but cryptocurrency is like the major tool for criminals who are online. Because there's no regulatory body. There's anonymity. Just really a hotbed for a crime. Right. You've like - we've talked about the Silk Road before. Emm. Dark web. Yeah. Using the dark web that are connected to buy and sell goods. All those goods are sold or bought with cryptocurrencies. Because it's much harder to track and to trace. Yeah. It's nowadays the markets are trying to get people to have their name connected to their wallet, but not every market requires that. And so, there is a bunch of people out there that have cryptocurrencies that have just a wallet with no name attached to it. Yeah. Because that was the original aim, that was the original meaning of cryptocurrency, right? They don't want a centralized authority to control all these money transfers. Would there be a lot of money laundering in cryptocurrency? Yeah. Like cryptocurrency, just in like 2021 alone, there was something like $8.6 billion of money laundered using cryptocurrency. That's not even the beginning, like every year that happens, there is other issues involved with cryptocurrency. When you have so much crypto, you can actually use that to affect or inflate the market. You have people that have large sums of cryptocurrency, not only are they using it to launder money, but they are actually able to increase the value of the currency they have, by just selling it to each other for the same amount of money, which increases the amount of trades, which makes people think that it's worth more, and then people buy it for more. Oh, okay. I think I've heard of this. This is called wash trades, right? Right. It happens on the stock market too, gold markets, but it's rampant and in some markets with like cryptocurrency. Yeah. So, it's the whole idea is I have some cryptocurrency, I just sell it to you, you sell it back to me, I sell it to you, you sell it back to me. And so, by doing that we're trying to make it seem that large amount of this cryptocurrency is traded on the market, therefore inflating the value of it. Right. I think the other problem with cryptocurrency is a lot of people obviously use it for speculation. So, like really really - like gambling. Right. Just like buying stock, you want the value to go up. People are investing money in the cryptocurrencies. And when you see like the increase in like the value of Bitcoin over the years, went from something that was worth pennies to being worth thousands of dollars. I think it's worth $30,000 now, and it’s worth $60,000 I think at the beginning of the year something around there. And so, people can take a small investment and make their investment increase 10 times or maybe even a hundred times their original investment. It's a market for gamblers. However, like we talked about last time, most of these cryptocurrency, they do not really have the staying power. They will not be able to really maintain that high value over long term or keep growing. It's very volatile to go up and down fluctuate wildly. Mhm. Yeah, when we look at just like we mentioned Dogecoin earlier, but you could have like five Dogecoin for a penny in 2020. But ...

We kind of talked about NFTs before. And NFTs kind of share a basic background with cryptocurrency, but we haven't really gotten into cryptocurrency before. So I think this is where we can kind of get into it. Yeah. This is where everything started basically. First of all, cryptocurrency在中文叫加密货币. I think many people think of cryptocurrency, they think of Bitcoin 比特币 or even Dogecoin 狗狗币. But what exactly is cryptocurrency? Oh, cryptocurrency is just a currency that doesn't have a central government or authority controlling it. So when you have your dollar, your Renminbi, someone had to print that or control the amount of it. And rather than that, It’s usually the central bank, isn't it? Like the central bank. But rather than that, this is something that's online. And there's like a digital ledger that has a list of everyone who has bought or sold the currency. And so they know who has what and this can be like anonymous. And that's why a lot of people really wanted it. But nowadays a lot of the exchanges are kind of starting to collect your personal data for tax purposes and things like that. I see. so let me slow this down a little bit. There's no central authority. 一般来说我们生活中接触的货币, 不管是人民币或者说美金日元, 它都是由central bank一般都是央行来发行的, but cryptocurrency essentially there is no authority, no central authority, no government involved, and no regulatory bodies, 没有这种监管的机构. So It's just everything stored in a ledger. You said像一个账本, a digital ledger. Right. And some people can be anonymous. They can - you don't know who they are. They're just an account number, but others might have to register. They might have to have their personal data there. Yeah, so oftentimes if you're looking at the blockchain, you may not be able to know who the person is. But if you go to like, for example, the government will know who this person is because they've signed up for an exchange and that exchange has tied their account number to their name I see and you mentioned blockchain. This was one of the hottest buzzwords a few years back, blockchain, 区块链. Till this day I still don't know exactly what blockchain is, but I know this is the technology behind cryptocurrency, right? Blockchain made cryptocurrency possible. Yeah, it is basically just all the data. Blockchain is the ledger. You have to decrypt and encrypt all the data. So whenever someone buys or sells something using the cryptocurrency or whenever cryptocurrency is traded, it has to go through authorization and they have to run the blockchain. In order to do this, they're using hundreds of computers or thousands of computers and they go through a process that's referred to as mining. So sounds you're like mining for gold. And essentially, that's what you're doing by using your computer to help the blockchain process. You're going to get some sort of payment. Let me stop you there. So mining here就是挖矿. It's like you are mining for gold or mining for diamonds. And this is a way to make money in this cryptocurrency world? Yeah. because rather than have - like a government doing all the mining or regulation, everyone is pitching in to do the regulation or to do the mining to move the data or to move the currency from one person to another. Oh, I see it's like a community thing almost. I've heard of people doing the mining, 其实我自己朋友圈里面也有人去参与这种cryptocurrency的挖矿.

She was the wife of Lord Leofric, a powerful and wealthy nobleman. Lady Godiva was known for her generosity and love for the people of Coventry, but her husband, Lord Leofric, was a stern ruler who declared heavy taxes on the citizens. The people of Coventry suffered under the burden of these taxes, and their pleas to reduce taxes were ignored by the greedy ruler. Lady Godiva, however, felt sorry for all the struggles of the common people. Lady Godiva argued and argued with her husband from dawn to night, trying to persuade him to reduce taxes for the people of Coventry. Lady Godiva thought of new ways to raise money and even said she would write to the king. Unfortunately, Lord Leofric was stubborn and refused to reduce taxes. In the end, Lady Godiva lost her patience and she made a bold and strange proposal to her husband. She said that she would ride through the streets of Coventry, completely naked, if he would reduce taxes and help end the suffering of the people. Lord Leofric was shocked that she would even suggest this but eventually agreed to her terms. Leofric knew how shy his wife was so he was confident that she would never go through with riding naked through the city. The people of Coventry soon heard about Lady Godiva's promise which spread like wildfire through the city. The citizens were grateful for any hope of relief from their taxes and they waited for the day of her ride. Lady Godiva, determined to fulfill her promise and alleviate the suffering of the people, prepared for the ride.

You know, all my time dealing with you. Thank you. And other British people in general. Yeah. Again, I’m not trying to stereotype. And with all due respect. Okay. I do feel like British people have this tendency to be quite sarcastic in their speech. Emm, would you agree? I would say yes, to a certain extent. 对。就是，英国人说话的时候很喜欢反讽,就很喜欢说一些反话。安澜，你知道中文里管这个叫什么吗？ 不是阴阳吗？ 对，就是，你还知道阴阳啊，这个不错。我们有时候开玩笑就说：“老阴阳人了”。 Really. See， there we go. Okay. You can't even control it. So, I thought in today's episode, let us do a few phrases that British people would usually say, but they don't mean what they seem to mean. Okay. I think we did something quite similar in one of our live streaming episodes. Yeah. We actually did an entire life streaming like a pop quiz thing of you quizzing me on all these read between the lines, the hidden meaning of British sarcasm. Ok. So, today we give this quiz to you. So, see if you can understand the hidden meaning behind the sarcasm. So, let's begin. Okay. Well. Let's start, first of all, with requests. Now we all know that British people they tend to make requests very very overly polite. So, … Like this “could you…I was wondering if you could…” Would you most awfully be able, you know, that type of thing, really really exaggerated. So, if your boss says to you “could you do this for me when you have a minute?” What does that mean？ Could you do this for me when you have a minute？Although it sounds polite, what do you think it means？Three, two, one? I think it actually means “Do it now.” Yes. When someone says to you in English, when you have a minute, the implication is that it's only gonna take you a minute you need to do it now. Emm, I see. The request is a bit of a tricky one. Because sometimes people might actually be very polite in this situation or they're being polite. But it could also be they are just trying to hide what they truly mean behind the politeness. Exactly. We would also use it if we try to make a point that this person is probably not the best at time management. Mhm. I remember there's also a lot of sarcasm around, not sarcasm, but hidden meaning about good or bad when you say is good or quite good, it's not good or what was that about？ For example, what does it mean if I say “ it's quite good”? It's quite good. I think when you say it's quite good, that means it's not really that good? Actually, means very good. Then why can't you just say it's very good？ Well. We just don't like to say something is very, we don't like to use the word very. Because it's, it's a bit too strong. Okay. So, if you hear very from a British person, chances are they are being sarcastic. Yeah. Yeah. Okay. You also say “not bad”, right？ Yeah, that film’s not bad, that's generally means also good. 嗯，跟中文的“不错”差不多 Yeah, a little bit, but “不错” normally means it's very good, while in English is normally means it's good. It's not too exaggerated. I keep hearing you say things like not too bad actually. So, if I ask “how was your day, 安澜, and you say "not too bad actually". What does that mean？

So we're gonna continue with Mamma Mia, the jukebox musical. Yeah. one of… maybe the first or one of the first jukebox musicals I can think of anyway, yeah. There's so many more now. They are everywhere. There seems to be one every few years somebody changes or adds the music from a popular band or singer and they're everywhere. Yeah. Okay. So, in the previous episode, we were talking about the background. We also walked everyone through the story, which is a fun light-hearted story really, they were lots of like little twists, little plots, but the whole idea is pretty simple. Right? It's just a girl who is about to get married. She wants to find out who her father is. And then the whole story unravels. So Oliver, what do you think are some of the themes in this particular story or in the musical? Well. I'm gonna be honest, I've watched it a few times and I struggle to see any major themes if I'm being quite honest, it feels too light-hearted to have anything really deeper than that. On the surface. It just like, it's just a feel good, happy ending musical. Yeah. It feels like something you go out, you forget about the world for a little bit, and not really think about any major issues or anything life important. But interestingly, there are some deeper or bigger themes hidden underneath all these song and dance. First of all, surprisingly is feminism. Really, feminism. Think about the entire setting, think about the main character is a girl. And the main relationship is actually the relationship between her and her mother, and how they had misunderstandings, and then eventually they reconciliated. And also, the mom is a single mother, although we talk about who was she with, but the fact is she wasn't like so hopelessly in love or groveling at any of these men's feet. She was enjoying her life. She was enjoying her friendship with her best friends. They're all women. If you think about it, it’s a huge group of women, it's like a support group almost. That's true. I do remember the songs where they were singing and dancing and enjoying themselves and talking about the worries and everything together and doesn't Donna, the mother, doesn't she own the tavern on the island. Exactly. Where they all are. Yes, yes, there's no men involved there. It's all female owners and management and such. Yeah. Yeah, and there's nothing like this whole toxic competition between women. It's more like they're very supportive of one another, if you think about it to have a kid out of wedlock, not knowing who the father is even nowadays is still problematic. Right? So back in the days, there was probably more social stigma or supposed to be more social stigma. Yet with the support of her friends, nobody was, for lack of a better word, slut shaming her. No, you don't get that feeling at all throughout the show. You're right. Yeah, there was nothing... There's confusion over who the father is, but there's no judgment on anyone, which is quite nice. Yeah. That's good. Yeah. And the other thing is, the only one that actually judged her a little bit was her daughter. Her daughter originally was saying that “no, I don't want to be like you. When I have a kid, I want to know who the father is. I don't want to be like you”. But eventually they also reconciliated. And the mom, Donna, the character is not just, you know, when you see single mother character, the stereotypical single mother is always like toiling away, suffering, being very lonely, being very just like hard done by that sort of imagery. However, in this single parent household, they enjoy songs and dance and love and sunshine, happiness. I think that is also like a more of a positive take on what a single parent household could be.

Suddenly, he caught up the hen, ran out of the room, opened the door of the castle, which the giant had left open, and descended the beanstalk as fast as he could. His mother was glad to see him again, and surprised at seeing the hen, which laid them three gold eggs every day. Jack’s mother took them to the next town and sold them, and soon became extremely rich. Some time afterwards, Jack made another journey up the beanstalk to the giant’s castle; but first he dyed his hair and disguised himself. The old giantess did not recognise him, and dragged him in as she had done before to eat him; but once more she heard her husband coming and hid him in the box, not thinking that it was the same boy who had stolen the hen. She put him into the same box, and told him stay there, or the giant would eat him. Then the giant came in, saying: “Fee, fa, fie, fo, fum, I smell the breath of an Englishman.” “Oh!” said his wife, “it is only the farmer, who has just been here. We cannot spare him for your dinner.” Then the giant sat down, and when he had eaten half an ox, he told his wife to bring his moneybags to him. She instantly went and fetched two large bags full of gold; and then left him to go about her usual housework. The Ogre counted out the gold twice, and then put it into the bags and tied them up. In a few minutes, Jack heard him snore. He escaped the box, seized the bags, and hurrying out of the castle, safely carried them home.

And it has been a long time, Oliver. Hello, it has been a very long time, yes. But I'm very happy to be back. It's nice to be back. So what is the first musical we're gonna talk about now that you're back？ I thought because it's been such a long time, maybe you would like to choose something for today. Okay. I was hoping you would ask that. Before I say the name of the musical, I want you to listen to this music. (Music) Does it sound familiar to you？ It does. I think I recognize the band who made those songs. Okay, so you know which musical we're gonna talk about today. I can take a very good guess, yes. And it is ? I’m guessing it's going to be Mamma Mia, the musical made around the music of ABBA, the songs we just heard. Yeah, I mean, I sort of got the feeling that Mamma Mia wouldn't be your top picks. It's not in my top ten, no. Yeah, because it's so lighthearted. It's such a fun musical and you like the heavier stuff like you want it miserable instead of lighthearted. It is more my style is the heavier hitting musicals with deeper messages, but I do enjoy a nice, lighthearted musical as well sometimes. There's a place for them, definitely there is . Yeah, I mean musical theater is supposed to be more lighthearted, right? Especially compared to things like opera. Oh, definitely so. Compared to opera and the standard plays, in many cases, musicals are the the lighthearted, forget the world for one evening and jump into a story with good music. You can dance and sing to later, things like that, musicals are a good escape. Okay, so Oliver, since you know a lot about musicals, even the ones that you don't particularly favor, can you give us a little bit of the background like when was the premiere and just a general background? Okay, yeah. So the musical first of all, it came out in 1999 in London. So that was when it premiered in London. And a year later in 2000, it made the trip over to the US, it has been all around the world since then. It is popular in many places, more than 50 countries and it's been on all of the continents. So it's a very, very popular musical. Yeah. It is very popular and has been on Broadway in West End, in London for so many years. So this musical is called a jukebox musical点唱机音乐剧jukebox is, you know the olden days when you go to a bar there is like a jukebox where you can put in a coin and you can choose the music you wanted to play. So why is it called jukebox musical? It's actually a really popular thing nowadays. Lots of bands are getting their own musicals. ABBA was one of the first, but since then there have been lots of them. They're called jukebox musicals because they use music that wasn't designed for the musical. It was released by a band. You could buy it in a shop or nowadays you can download it and listen to it online, but it's not connected to the musical. People have used that and made the musical around it, rather than the other way, which is more common. Yeah, it's basically, the traditional musicals, they are completely like original songs. They were written for this particular musical. But a jukebox musical is, first of all, there is a very popular singer or very popular band. And then because their albums or their songs are so popular, people... the producers decided to make a whole musical based on their existing music. That's exactly yeah. They're kind of using the popularity of the music that's already there to create a musical. So they make a story to fit the music rather than in the traditional way they make the music to fit the story. So it's kind of a reverse, but it does mean they're really popular with audiences because everybody knows the songs, everybody can sing along. So they're really popular. Especially if you're a fan of the band or the singer. Definitely yeah.

So 安澜, one of the other episodes we talked about British people being sarcastic usually saying words with a hidden meaning. Oh, yeah. But I've noticed another quality of British people… Okay. which I see again in you a lot. Don't worry, It's a good thing! The understatement, so like the modesty, 英国人很喜欢自谦, 甚至是自我嘲讽. 安澜is a typical example. So if one day he's done something great, if he has made some sort of achievement, if I say congratulations, that's such a job well done. 安澜would give me some joke, some self-deprecating humor就是那种自嘲或者自我贬损的这种幽默. And that I've come to know that is not just you, that is actually a quality of British people. Yeah, I would say British people like making jokes about themselves. Even as a country when we display our country or we present our country to the rest of the world, we also still use lots of self-deprecating humor even though it was years ago now. But I think one of the best examples is the Olympics that were held in London over 10 years ago and the opening and closing ceremonies. It was filled with jokes. It was filled with jokes about England, and it was filled with jokes about the UK. I think this is something cross-culturally, it's quite difficult to understand, especially for Chinese because we focus a lot on national pride. Yeah, we can complain about our country, but it's rather unthinkable for a lot of people to make fun of ourselves in that way. Again, this is no judgment not saying which side is good or bad. But I've really noticed in the UK this ability to laugh at yourself and not to take yourself too seriously. That's true. I would say British people we like to laugh at ourselves, we don't really take ourselves too seriously. And it seems as a good thing. It's not seen as a negative. It doesn't mean that we have low self-esteem. Is the country, isn't it？ Is the country. It's our culture where being seen as modest and humorous are seen as positive traits. They're seen as virtues.

Jack was a thoughtless boy, but very kind-hearted and affectionate. There had been a hard winter, and after it the poor woman was very ill. Jack was unemployed and they gradually grew dreadfully poor. The widow saw that there was no way to stop Jack and herself from starving. They had to sell the only thing that they had left - their cow; so one morning she said to her son, “I am too weak to go myself, Jack, so you must take the cow to market for me, and sell her.” Jack liked going to market very much; but as he was on the way, he met a butcher who had some very large, green beans in his hand. Jack stopped to look at them, and the butcher told the boy that they were very valuable, and persuaded him to sell the cow for those beans! And Jack was so silly that he agreed to give his cow for some worthless beans. When he brought them home to his mother instead of the money she expected for her nice cow, she was furious and upset, shouting at Jack for his stupidity. He was very sorry; but, he said, he might as well make the best of his bargain, so he put the seed-beans into the ground close to the cottage. After he planted the beans, Jack went to bed. The next morning when he got up, he found that the beans had grown, till the bean stalks had reached the sky and Jack couldn’t even see the top of the bean stalk. Greatly surprised, Jack called his mother, and they both gazed in amazement at the beanstalk, which was not only very high, but was thick enough to bear Jack’s weight. “I wonder where it goes?” said Jack to his mother; “I think I will climb up and see.” His mother didn’t want him to climb such a dangerous height, but Jack managed to persuade her to allow him to start climbing it. He knew that there must be something wonderful in the beanstalk. Jack instantly began to climb, and went up and up on the ladder-like bean till everything he had left behind him, the cottage, the village, and even the tall church tower, looked tiny, and still he did not see the top of the bean stalk. Jack felt a little tired, and thought for a moment that he would go back again; but he was so curious that he didn’t want to give up. So after resting for a moment he went on, and at last reached the top of the bean, and found himself in a beautiful country, surrounded by trees; and not far from the place where he had got off the beanstalk was a fine and strong castle. Jack was surprised that he had never heard of or seen this castle before and was thinking who could possibly live there. While Jack was standing looking at the castle, a very strange-looking woman came out of the wood and walked towards him. Jack took off his hat to the old lady, and she said, pointing to the castle, “Boy, that castle belongs to you. A wicked giant killed your father, and took it from your mother; you must win it back from the monster who now has it.” As she stopped speaking, she suddenly disappeared, and of course Jack knew she was a fairy. He was surprised; however, he walked up to the castle door and knocked, and an old giantess came out. She did not wait until he spoke, but pulled him in at once, for she ...

We're gonna continue that and we're gonna talk a little bit about cars as IoT devices. Em, in the previous episode, in the basic one, we were talking about mostly about these smart home devices like we were joking about our fridge talking smack about us behind our backs, and all these you said like thermostat setting or setter or like smart locks. But cars that seems like, I don't know, it seems pretty big as an IoT right? It has a lot of built ins. YEAH. We think about a car today. They already have a lot of sensors already built in. They have the thermostat, they have things related to GPS, they have light sensors and so when it gets dark outside, your front lights will automatically turn on. So there are already tons of IoT devices in the car. However, our future cars will not just have IoT devices, but will be in a sense A IoT device themselves when we go to more like self driving cars. Self driving cars, those cars that you don't have to drive, right? It just drives on its own. Right, Let me get this straight. That means our car will be if we see all of these devices in the internet of things or on the internet of things, if we see them as dots, in the future these cars our car will be one dot containing lots of bells and whistles Yeah, because like all the cars will be interacting with each other. They are going to connect probably to a network of some sort. And they are going to know the position of other cars as those cars are moving around so that the cars can kind of avoid, but it can also be a way to manage the traffic system. Because if there's a network that all the cars are connected to, and then the traffic lights are connected to those, they don't have to follow a regular schedule. They can see ok, if we turn this light red now then the cars that are going can move through and then we can change this light to be green. And It'll help the flow of traffic in the long run. Wow, that kind of blows my mind basically in the future when everyone switches to self driving cars, every car is connected to the internet of things. That basically means we'll be in an almost automated ultra smart system or sort of like transportation infrastructure, then we no longer have to worry about things like traffic jam, congestion collision any of that. Yeah, we can avoid a lot of it. I mean there are still going to be some of those things. There will be accidents, there will be collisions from time to time. No system is perfect, but it will definitely be reduced quite a bit. (em) Now there is this idea of cloud computing everything these days is on the cloud, as they say. Now we're going to possibly move into a new field called Fog computing . Hang on a minute, so I haven't even figured out fully how cloud computing works now. People are now the old technology is moving on towards fog computing like 雾计算,从云计算到雾计算 . What is fog computing? Like we have cloud computing like data is stored on the network rather than on your computer, so you can access that data anywhere. (yeah) But fog computing is where they eliminate the need for the internet where we don't have to even go on the internet. So all the devices themselves in one area create their own network. And so It's kind of like a fog in one area. There's lots of cars over here and they all have their own network and so they kind of referred to that as a fog rather than being like in the cloud on the internet. It's a fog that's outside of the internet. They're all kind of just working together. So instead of controlling every car with an internet based or cloud based system, now they get rid of the cloud and just cars will connect with one another. Right. So it'll be less centralized, it'll be decentralized from a network. Things can still connect to a network. But in a situ

So what are we gonna talk about today? Today we're gonna be talking about the internet of things or IoT. The internet…The IoT中文叫做物联网。internet是互联网，IoT, internet of things 是物，就是物件的物，物联网. I mean, I have seen the definition somewhere and it seems to be referring to all the things are connected rather than the computers. Could you walk us through the basic definition of IoT? So, basically, IoT is just a group of things that are interconnected. They can be on the internet or through their own network, but it's not computers. It's like devices that have sensors in them and software that they used to communicate. And so it might be a button somewhere that you push and it communicates with something, or it might be a temperature sensor that we used to find out the weather in our smartphones. So, is it like one of those, for example, if I've got like a smart fridge refrigerator, that can be part of IoT? Right. Yeah. That's one of those IoT devices. Emm. And IoT means they are actually able to connect with each other and what communicate? Yeah. They basically they inter communicate on their own. When we use the internet, we go online and we look up Information, but an IoT device connects to the internet or through another network, and sends Information to a hub or to another device directly, without any human interaction necessarily. Okay, starts to sound a bit creepy. So my refrigerator can be sending things about my home to another refrigerator, for example, your refrigerator? Well. It's not just gonna go talk to another refrigerator. However, you know you have your phone, and you probably have an APP on your phone that you can use to connect to the refrigerator, and then look at what's inside of your refrigerator or maybe your refrigerator will send you some Information saying “you only have two eggs”, you might want to order two more or more.
