The presidential candidate of the People's Democratic Party, PDP Attiku Abu Bakar has told the people of Abia state not to waste their votes on any candidate that cannot win the election, assuring that a main opposition party will emerge victorious in the coming polls. Addressing a rally in Umwah here on Saturday, he warned voters against basing their choice of religious or tribal sentiments, recalling how PDP passed governments, admitting the country without playing any of those cards. Abia is PDP and PDP is Abia. In spite of that, we are very, very optimistic that in the forthcoming elections, you will come out and cast your vote for PDP. You have every reason to cast your vote for PDP because, let me tell you, PDP is going to win. PDP is going to win. Therefore, it is better if you are on a winning ticket than on a ticket that cannot take you anywhere. And therefore, it will appear to you not to be distracted by other political parties who may be playing other religious or ethnic card. In PDP, we have no religious or ethnic card. We play an Algerian card. A card that will bring everybody on board and a card that will bring, it will have a sense of belonging to every part of this country, to every religion, to every ethnicity.


Kind酷ja kya baozi International Day of Girls in Icities mini zwei For Indian lotus Children Chicken Women to be learn science technology algebra has where they were in position While an equality exists in every industry, this gap is most pronounced in STEM fields where less than one third of STEM roles globally are held by women. One of the main reasons for this gender divide is the lack of encouragement and mentorship to empower girls and young women to pursue leadership roles and develop the necessary skills and networks to successfully achieve their objectives. Adresing such challenges is a priority for the international girls in ICT day. It is with pride that I noted the fact that since 2011, nearly 380,000 girls and young women have taken part in more than 11,400 international girls in ICT day celebrations in 175 countries, featuring role models who inspire girls and young women to pursue STEM education and careers. In order for us not to lose momentum and to also keep our eyes on the ball, the girls in ICT day has become a global movement seeking to achieve digital gender equality. Dear friends, I am strongly convinced that change is not a title, change is a mindset, a habit. Girls can make invaluable contribution to society and deliver change, capable of profoundly impacting the community they live in, especially through digital. Forstaring a greater presence of girls and women in the tech sector generates much needed inclusivity in the design and development of digital tools and platforms. That's why the Telecommunication Development Bureau has launched numerous initiatives to encourage the participation of women and girls in ICT at all levels. Under the theme leadership, this year's Girls in ICT day will be celebrated on the 25th of April. I invite and encourage everyone to organize and take part in the countless different events to celebrate this special day. Feel free to get your inspiration for ideas from our website or by following us on hashtag Girls in ICT. Thank you and happy international girls in ICT day.


Spring Cleaning is here and Appalachian Wireless has the deal to get you started. Get a Samsung Galaxy S8 for a penny or a Galaxy S8 Plus for only $89.99 on the region's best network. Better service? Bigger savings? That's today's Appalachian Wireless. So your agreement requires you to store for details. The City of Preston's Barber now has a new vision for what it hopes to become. Last night, during a special city council meeting, the city's new strategic plan was presented to the council and the public. And like any good plan, it starts by cataloging the things the community already does well. What I see in Preston's Barber that's unique is right now there are a lot of moving pieces. There's a lot of activity. There are a lot of people coming into the community for tourism related things such as biking and, you know, rafting and that sort of thing. But you also have a small place that is very vibrant. You have a lot of small businesses here. You have a lot of music and arts and entertainment and that sort of thing. And so, you know, I think there's a great opportunity here in Preston's Barber. The plan offers a comprehensive look at how to strengthen the city's economy through such activities as building a high-speed broadband network and promoting the health care industry. It also addresses housing needs and the little things to improve the city's quality of life. In short, it creates a picture which Mayor Les Stapleton can already envision. Preston has a downtown, hometown field with some tech jobs, light manufacturing on the periphery ends of town. And we've got our youth coming back home to be a part of our community. Both men say the plan and the process behind it are important because the alternative of doing nothing leads nowhere.  You die on the vines, that's it. We can either move forward or die on the vines. We're set up for it. And we're going to move forward. My philosophy has always been you're always moving forward or you're moving back, but there is no doing nothing. And so, I think that while the momentum is good, you want to keep pressing forward and always trying to build upon that. And now we've got a purpose and the people are here, and that's going to see it. We've got a direction, and we're going to follow it. You can find a link to the full plan on the EKV-TV website. Reporting in Prestonsburg, I'm Ralph Davis for EKV News.


The new year stuff, you've got to be Jonathan, are you pals with him? No, he's a strange wee ranger man, I know Johnny well, but no, I know Johnny well, but no, no. Because you, in that only excuse, you are the main character. Listen, I think, I think Johnny must be, he must be doing something, I don't know what he's done, he got that contract with the baby, see, because it's, it's, it's, it's no very good now, I mean, he went off the boil, there's so much that he could have done. You know, I was, I was, I was maybe costy when he got put in gardening, leaving, I never done nothing like that, and I'm going, why do you know that? Because he's a great lad, and he's a good fund, and he would take it the way he's meant, never done him, and I'm thinking, he's listed probably when he's doing politicians and pop stars and everything, and that's not what he's supposed to be about. So, I mean, it does me, it's great, listen.  The best one for me was, you know, the petrol station or people ask you, they always ask you, what's your favourite thing? And I've never seen those I met the girls that was in there, No, no, I was one of the gunkers over here. Well, did that come through then? Well, I don't know. Is that because you were always full? I apparently had a bar when I used to have a bar in Glasgow. And my brother worked in the bar, and I was trying to open up a place called School Dinners. It's a restaurant, but you get whipped and all that. And get arrested. You can imagine why my... I was doing interviews, and I came into the bar, and I had to go on the bank scene checks and all the usual stuff. And my brother says, look, there's some girls here for interviews, for the School Dinners and for the restaurant. And I said, OK, something in the back of the bank. I came in and I said, where are the girls? And he was full Differ's pal, full Differ Rates having for Johnny. And apparently his pal was at the bar, speaking to my brother. And he says, what do you say? And he says, I, where's the girls? And that's when he came for me. He just changed it. He wears the buzz. He wears the buzz because it stopped way back then. It stopped big time. People say, say that and go, no, I don't say that.


Welcome to Digital Asset News or Dan for short. My name is Rob and today what I want to do is bring back Alan Sokolitsky. He's the Chief Financial Officer for Masterworks and we're here to talk about just the nuts and bolts of Masterworks. Alan, thanks for coming back again to answer some questions. Thanks for having me. Happy to be here. All right. So there's been a little bit of grumblings, especially with the issue with trust, especially in our markets, which spills over to other parts. So they're going to go over just the basics. First of all, what's Masterworks and why diversification? Second of all, we go through proof of reserves. We have some kind of proof of art, meaning that the things that you have bought as far as our pieces, how do we know such things? Also, 20% fee upon sale seems kind of cheap or kind of steep. And then lastly, how does the secondary markets work? So the first things first, Alan, just basically people have never heard of you or what's gone on. What is Masterworks? Yep. So Masterworks is it's basically the first company to make multi-million dollar works of art, so paintings, available to invest in on a fractional basis. So you can buy shares in a Banksy, a Bosquiat, a Warhol, all the major artists. You can come to our website, you sign up for an account. And ultimately, you can become a partial owner in one of these multi-million dollar paintings, somewhat along the lines of how if you buy shares of stock on the stock market, you're kind of a partial owner of a company to somewhat along those lines. There are a lot of differences, but nevertheless, the idea of being a partial owner is pretty much the same. You know, the art market, it's a nearly $2 trillion asset class. So we're not talking about something small. We're talking about something pretty gigantic. You see it around us in museums everywhere, and it's a really great diversifier for portfolio uncorrelated, and we think a lot of investors should consider it. Yeah, it's something to consider. And this is just to get everybody's head perfectly, is that it's not about getting into Masterworks and putting your entire life savings. It is a small diversification. This is mine right here. I got mostly in cash and real estate. But Masterworks, I've allocated a little bit to it. I think that's kind of how I would like to do things. It might be different for everybody else, but in this day and age, I mean, look, the S&P 500 today is December 22nd, 2022. And we're looking at almost a 20% drop this year alone in S&P 500. So if you're investing in S&P 500 and just saying, set it and forget it, it's kind of hurting right now. Same thing with the NASDAQ down 32%. And let's not forget our market itself. We're down market cap-wise 63% year over date. And that is not to include, or that actually includes everything, but if you're in a specific altcoin, you're hurting even more so. So again, Masterworks, how it worked for me, I called them up and I said, hey, I'm looking to invest in this. Tell me what it's all about. It took them between 30 and 45 minutes to get it through my head. What it actually was, they answered all my questions and they told me very specifically, Rob, the things that you want to do does not equal to what I just talked to the last person and the person before that. And they made it very crystal clear of what my goals could be, what I told them, and what they should or could do with Masterworks. So again, if you're just thinking about this or this is the first time you heard it, this is not the only place you can get answers before you can even invest. You have to talk to these guys and just to make sure if it's right for you. And I'll be honest with you, I've had other subscribers say, hey, they told me it wasn't for me. And that's fine. And I would I would really emphasize that we're basically, I'm not necessarily going to say we're the only platform that does this, but I'm pretty sure most platforms do not do this, which is to say, you can't actually just sign up on our website and automatically make an art investment. We actually don't allow any investors to invest in art until they've actually spoken to someone from our membership team, because we actually take risk management and our clients wealth very seriously. So we ultimately work with all of our clients to determine what is the appropriate allocation to art for your portfolio. And to be honest with you, in a lot of cases, we actually guide investors to have smaller allocations relative to what they might have thought they should invest. So we're probably one of the only platforms, if not the only platform that actually is willing to do something like that, guiding you to invest less than you might have thought you should. Yeah, sounds good. So let's let's do this, let's get into the whole trust aspect. So the first thing is this, we've got an issue here in crypto world, which is people say, I've got Bitcoin, I got a three on my exchanges, and all of a sudden poof, it's not there. That's called proof of reserves, proof of liabilities. How do we know Alan for everything with Mashworks that you guys have purchased the art? You haven't just like said, hey, we've got a Banksy, and here it is. How do we know? Yeah, so you know, this actually in some ways takes us back to early days in masterworks history, because when we were first trying to figure out what is the best way for us to even fractionalize the paintings in the first place, meaning how should we go about making them available on a fractional basis. The route that we took, which is to have every offering qualified by the SEC and have all the documentation on the SEC, that wasn't the only option. We had actually considered using blockchain, but what we quickly realized is because a lot of investors were sort of learning about art for the first time, the way that we wanted to make information available about all of our offerings was a way that would be as public and as transparent as humanly possible to give investors a lot of confidence in what we were doing. So that's a lot of the reason why we actually decided we are going to securitize these paintings. We're going to make them public vehicles with the Securities and Exchange Commission. So you can either go to our website where you'll see a link for every single painting. There's a link that will take you directly to the SEC's website, and you will get an extraordinarily lengthy document that is going to talk about everything related to that particular painting. It's going to give you a history of the artist, a history of the painting, who owned the painting before and who owned the painting before. That person, it's literally going to lay out in exhaustive detail anything and everything that you would want to know. And again, the reason why we wanted to do this through the Securities and Exchange Commission is because we knew that because this is an investment that a lot of investors have not thought about before, we need to do it in a way that is most likely to give investors the maximum amount of trust, and that's why we decided to do it this way. Gotcha. Okay, so that helps out a little bit with the transparency part. Let's talk about this one. 20% fees. Now, when I heard about this and I talked to the guys over there, just so you know on a very upfront, like this would be 20% fees, they laid it all out for me, but it's been over a year. I purchased a Banksy and a Bastiat, and I can't remember exactly how this all works. So Alan, could you break it down for us? Because some people would say, why don't I just invest into something like just put it all on the crypto because the crypto goes up 100%. It also goes down 99% sometimes. Yeah, so when it comes to the fees, for alternative investments, and let's just even put art aside, if some of your viewers invest in other alternative investments, whether it's private equity or hedge funds or others along those lines, the pretty standard management fees and performance fees for alternative investments in the industry is let's say 1.5% to 2% management fee and 20% of profits. Our business, we are basically, we think very much average or even slightly below, we're actually at 1.5% management fee and 20% profits. So we think we're pretty much right in the ballpark with other alternative investments. That 20% on profits, I just want to be clear what that specifically refers to, because let's just say in general, I can totally imagine that somebody who just hears the number 20% fee, that on its own is probably a little bit terrifying to hear, but that's a fee on profits. So as an example, let's say we have a painting that we make available for a million dollars, and let's say a few years go by, we sell the painting for $2 million, that means there's been a million dollars in profit, right? It went from one to two, that means a million dollars in profit. So 200,000 of that would go to us, and 800,000 of that goes to investors. And the reason why investors are so interested in having asset managers who actually have a fee on profits, and investors actually want managers to charge a fee on profits, is because it is probably the biggest and strongest form of incentive that you can give an investment manager to do a good job with what they're doing, because they know that the more they are able to generate in terms of performance, that means that they'll be able to generate more for their investors as well as generate more for themselves. You actually want that. Yeah, I'm okay with that, with paying those types of prices. And then, like we just took a look at the track record, not a little bit ago, but we can see that so far, I mean, annualized profits themselves are looking pretty reasonable, as far as like the pennies are sold, 33%, net of all costs in fees, 27%, golem, condo, so on and so forth. So yeah, I think it's just something to say that this is all after everything. Yeah, I mean, that's really, that's one of the important considerations. I think a lot of investors, if you focus too much on the fees alone, almost like in a vacuum, you sort of lose sight of what's, I think, significantly more important, which is, is the performance that the manager generating, is that performance still really good after you pay the fees? And I think what the performance of our platform has shown, I mean, we've sold paintings, you just ran through some of the example, we've sold paintings that had net returns, meaning after fees of over 30%, there have been a number over 25%, a number over 20%. So I think at the end of the day, what it goes to show is, if you are able to generate those types of performance numbers, especially in the market we're in today, that's really what matters most. And sometimes I kind of struggle bringing up the performance of stocks and bonds this year, because it has been challenging and it's been challenging for a lot of investors' portfolios, but it does in a way highlight one of the points I've been trying to make about fees, which is to invest in stocks these days, the fees you're going to pay are effectively zero. I mean, they're not literally zero, but they're close to zero. But despite the fact that you're paying close to zero, the stock market this year is still down nearly 20%. With bonds, you're also paying close to zero in terms of fees, but bonds are down over 10% this year too. So I guess it's all just a way of saying it's important to look at fees, but you need to give those fees some context. What's the performance you're getting for the fees? Yeah, that's a big thing. And that would actually leave me up to the next point here, and I'll kind of roll into this as the secondary markets. And before I roll into that, I would just say that now we talked about sharp ratios before, I'm not going to do it here. Again, there'll be a link in the description. You can check out what Alan talks about sharp ratios, but anything above one is doing pretty good. And 1.5 to almost two is utterly incredible. And we can see sharp ratios being quite high. But on top of that, there's just one little piece here I want to make mention. Less than 2.4% of artworks reviewed by Masterworks actually gets bought up and offered to persons. So Artist Market Analyze 7100 selected 74. They were offered 5677. And this is what they have. So again, it's not like they get every single one out there. They're trying to get the best because they're trying to give us a great return and go from there. That's the idea. I mean, I'm sorry to interrupt, but it's so important to emphasize this because the truth is we've had several paintings over the last few months. These are several multimillion dollar paintings that actually sold out in 15 minutes. So if you were to take that into consideration, and you would probably very quickly realize, wait a minute, if they have paintings that sell out in 15 minutes, they probably should want to buy up as many paintings as they possibly can and make those available because there's so much demand for what they're doing. However, we would be throwing the investment process entirely out the window if we actually decided to do that. We are entirely focused on generating attractive performance for our investors. And that requires being extremely selective. And if that means that our paintings sell out in 15 minutes and we're not just buying anything and everything under the sun, then so be it because we are committed to generating attractive performance. And then this will be leading to the next part about liquidity in the last question. So when we talk about these holds, because in our space, you can see like 100-200% increase in price in a week. That's just the bench of the beast. However, here, we're talking about year-long holds, two, three, five-year type of thing, right, Allen? The guidance that I give investors all the time is to expect three to seven years, roughly. That would be five years on average. I also point out though that there's some irony when I say that because most of the paintings that we've actually sold so far were opportunistic sales in the sense that we were approached and we were given very attractive offers for the paintings, so we decided to sell them sooner than our anticipated three to seven-year timeframe. Most of them actually got sold at two years. However, I'm always trying to sort of advise and caution investors that when you go into this, expect it to be three to seven. Doesn't mean it can't be shorter, but expect it to be three to seven. The long game. And then people ask me, well, what happens, Rob, because this is a very e-liquid market. I mean, it really is. So what happens if I need to get money out? Something happens and whatnot. There's a secondary market. And here, this is my account itself. If I go over to trading on the very top, from what I remember you telling me, Allen, it's after three months, after all of the shares have been purchased by the consumer or by the retail market, once they're all totally sold out, three months from then, then these shares, these fractionalized shares of fine art, get put on your secondary market and you can trade if you so need to. So I'm going to look at my Banksy. This is a gift shop. That's mine. So I bought it for $20 per share. Right now it's at a whopping $19.98. I'm okay. If something happens to me and I illiquidate, okay, I'll liquidate, but it's there for me. Is there something I'm missing now? You actually just explained it exactly the way that I would have explained it. You can see that there was that button on the right just now on the screen that said you don't have a Templom account signup. So Templom is basically the, it's a firm that we partnered with to sort of automate the trading that takes place on the secondary market. That's sort of been sort of a big advance for our business. We were very forward thinking when we first started Masterwork several years ago in even having a secondary market in the first place, but admittedly that secondary market, it operated kind of like a bulletin board. There was not a lot of automation. So yes, it functions, but you would imagine that something in this day and age should function a lot more efficiently than it did. So we've had, now we have this partner, you sign up for an account and basically there's a lot more automation that happens in the buying and selling. So think of it as, you know, a natural sort of progression and improvement in our business. And we are always looking to improve our business to every extent possible. Excellent. Alan, thanks again for stopping by. Everybody, if you're looking for more information, we did a deep dive into this. There's a link in the description. It looks just like this. And underneath there where it says deep dive video, you can go more in depth also to sign up or just to talk to the people over at Masterworks like we talked about in the beginning. You can do so, but just be aware it's going to be like a 30 to 45 minute conversation just like what I had. So Alan, I appreciate it. You stop and buy. Thanks so much for having me.


Ten more English expressions with the word NO from espressoenglish.net. NO is one of the most common verbs in English, and I know that you know what it means. But what you might not know is that we use this word in many idiomatic expressions, and you're going to learn ten of them today. Number one, for all I know. This expression means, according to the information I currently have, but implies uncertainty, like you don't actually have much information. For example, I'm not eating those mushrooms you found in the woods, they could be poisonous for all I know. Number two, know your stuff. If a person knows their stuff, it means they are very knowledgeable and skilled in that area. For example, this carpenter really knows his stuff because he has 30 years of experience. Number three, know the drill. This means to be familiar with a standard procedure or what is supposed to be done. For example, Nicole has organized the past three conferences, so she knows the drill. Number four, know where you stand. This means to be aware of your current position or situation. For example, I know where I stand and I'm not authorized to make that decision without consulting the director. Number five, it takes one to know one. This phrase is used to insult someone by saying that they are the same as the other person who they are criticizing, accusing or complaining about. For example, Bob says that John is a hypocrite but it takes one to know one. This means I think Bob is also a hypocrite. Number six, you don't know the half of it. This expression means that someone only knows about a small part of a situation but there is a much bigger issue that they are not aware of. For example, I heard you've been a bit busy with work these days. Oh, you don't know the half of it.  Number seven, not know what hit someone. If someone doesn't know what hit them, it means they are very surprised and shocked by an unexpected event that has a big negative impact on them. For example, when my wife left me for no reason, I didn't know what hit me. I'd been under the impression that our relationship was fine. Number eight, know no bounds. This expression describes something that is or seems to be without limit. For example, she's always coming up with new ideas. Her creativity knows no bounds. Number nine, what does he or she know? This question is used to say that someone does not know anything about a particular topic. For example, I wish my brother would stop giving me parenting advice. What does he know? He doesn't even have kids. Number ten, who knows? This expression is used when nobody probably knows the answer. For example, how long is this flight going to be delayed? Who knows? I guess it depends on how long it keeps raining. If you would like to learn more English idioms, click on the link in the video or in the description for more information about my English idioms course, which will help you discover, learn and practice idiomatic expressions. By the end of the course, you will have learned 260 common idioms used in everyday spoken English.


Good afternoon. It's a pleasure to be here. It's my first time here. I'm from Brazil. And I apologize for the presentation. It's not perfect. I have lost my luggage. I'm from Brazil and my luggage was lost during two days. Some hours ago we received the components for the demonstration with the material for the demonstration. And they saw it to us a little bit rush with the presentation. At least I'm here. I lost my luggage in the morning and afternoon before I arrived here. I'm talking to you about the scientific micropipers for microcontrollers in the IEP. Why scientific micropipers? I'm a physicist. But I work a lot with computational physics. And I try to use IoT, microcontrollers, programming, using the formalization that is needed for sensor data. So I put a critical view about the many sensors that IoT are making available for billions of people. But this data of these sensors should be analyzed in terms of error, precision, how many digits, etc. MicroPython is a pre and open source implementation of 523. It's not. It's 100% compatible. It's something like 98, 99% compatible. Because it was meant to work with tens, for example tens, k bytes of the wrong. It's a pie to three, but very optimized. It was created by Demi and George. He's a physicist of Gauss II. And it was created three, four years ago. And he created the pie board, the first board, the language. And there is a community around him. So the site of the MicroPython, there is a test drive. Sometimes it is online, really. And there are documentation, etc. There is no audio here for the images, the firmware. For example, for many boards, five board one, five board light, and Wi-Fi that I'm showing here. And the, well, MicroPython until 2015 had only two boards, two hardware boards. By board and Wi-Fi. Wi-Fi with Wi-Fi. But in the beginning of last year, we had some releases, like MicroPython ported it for ESP8266, BBC MicroBeat for more than one million children from Nightpeak Kingdom. It was given for children of 11 to 12 years old. And you can also buy BBC MicroBeat. Wi-Fi 2 with Wi-Fi and Bluetooth. Low Pi, it was the first microcontroller with Wi-Fi, Bluetooth, and Lada. And it was, naturally, MicroPython. And the other board, side Pi with C ports, side ports. OpenEV, it runs MicroPython and has a camera, a little camera, what optimizes to machine vision. All these boards run MicroPython. These two don't run MicroPython, not even. You have to install MicroPython. So, for example, by board, the first board, this version is a new one, but the first one was almost the same. Wi-Fi, the second board, Wi-Fi first. MicroPython project for ESP8266 last year. BBC MicroBeat, and you can, yes, there is Python here. And you can develop without installing any software. You can use the browser to develop. It's very important for children and parents to have a simple tool to develop. Wi-Fi 2, okay. Low Pi, and OpenEV, a new version. It will be released, I think, next month. And the older version. So it has a very small board in microcontroller with a camera using MicroPython. Okay. And the, sorry, I don't have time in the rush. The free memory of these boards, these board boards, sorry, is between 8K bytes, BBC MicroBeat, only 8K bytes to almost 100K bytes of a pipeline. Okay. So to develop for MicroPython, it's different from developing to Python, because you have your memory constraint very important. And about the demonstration, first I'll show almost the last one. This microcontroller, this board is low Pi with a lot of, okay, so you can have some kilometers of the communication, 20 kilometers per second, approximately, until just some kilometers, depending on the region. BBC MicroBeat, here, excellent price, and it has been used for one million children. And this year, there will be a MicroBeat for an international version. There is the other countries. So MicroBeat is now an organization, not the only rich one. And it's simple to remember when you are running, not in front of a lot of people. Okay. And I will use this. For example, it's very simple to use. I recommend to use MicroPython in the interpretable mode, interactive mode. You can also make scripts, of course. And so I use a terminal using USB serial connection. Okay. To enter in MicroPython on the first board. It's a new version of the first board. Okay. So this common. It's zeroes, MicroPython, almost the last version. Okay. There is a new version in general. And it's not the compiler language. Yes, it's Python. Okay. It's like a microcomputer. You have a microcontroller. Running Python almost has an operating system. So it's the dream of Python users. Only Python. It's not the leader, it's not the macOS, not Windows. Only Python. Almost full Python. Okay. And, well. Some immodulis are already loaded. For example, the Python model has a lot of subimodulis. For example, information. The third information of this model, microcontroller. You have here about 100 k bytes. And the flash memory is something about 90 k bytes. There are some files there. So it shows less. And yes. You have the reviews of the version of the five-word. And it's very simple to read. I show a sensor connected to the ADC analog to digital converter of this model. This model has some inputs with 12 bits of the analog to digital converter. And to read the ADC part, it's very simple. It's one line of code. Okay. Yes. I have read the model. It is oscillating because I have here infrared rangefinder of the sharp here. It can measure the distance between 10 to 150 centimeters. So I will run a script. Okay. And this is what I'd like to show that. Today data is stable. The physical quantity is stable. They read it is not stable. You have a lot of noise. All the sensors have noise. All the physical quantities, I'm a physicist. All the measures of the physical quantities in the world have errors, uncertainties. And the IoT community is forgetting this important thing. When we are publishing a system of data, it's important to take into account this reality. So the quantity here is not stable, the distance. And I will run another script to show the statistics of these readings. Okay. So the distance of my hand was 17 centimeters with a standard deviation without a statistical treatment. It was a huge, more than 1 centimeter, the standard deviation. With a statistical treatment removing some peaks, some data not good. It was reduced. And now I will show when I increase the distance, when I increase the distance, the error is increased. For example, they have to increase it more. So the error is increased with the distance. It's not constant. Here I will import another script with unscented calculation. So I have imported a module. I have created a module from Python to micro Python. Calculate the unscented errors from error propagation. Here I have to put the obstacle here. So we have 70 centimeters, which are error of 1 centimeter. But if the distance is increased, the error is increased. Okay. And this is done by error propagation, sensitive propagation. It's called very simple scripts. This code is a class. And it's possible to run in machines, in micro Python boards with free memory, as well free memory. There's no problem. And this code was not available before. Here I will present another board. Here I have ESP8266 microcontroller, configured to be micro Python. And the serial part is a little bit different. There is a lot of sense connected here. It's a BME-280 sensor with pressure, humidity, and temperature. All of them have unscented errors. So I will show a statistics. Oh, before. Just to show that this microcontroller has about 28 K bytes of rerun. Okay. I will show the reading of the sensor. Oh, yes, it's working. So we have the pressure reading. It has a lot of noise. And I run the same sensor with other configurations. Because this sensor has many modes of reading. And in this new configuration, the error is a lot smaller. So it's very important to understand the sensors. The PDF of the sensor has about 52 pages. It takes a little time. So the sensitivity is just 4, instead of a very huge one before. And the web server running on this micro Python mode. And it shows the three quantities physical quantities with the errors. And you have here, you can see that the errors. For example, we know before measurement parameters that you can configure the error estimation of the sensor. And the majority of people expose the data sensor without showing the error. The error is there. It's very important. And the scientific model is available for micro Python. The math model is available. Not exactly the same for all words. For example, we should be committed. It's very limited. You have for Python a fast Fourier transform in a simpler code available for micro Python. It's very fast. And you can compare with a super computer where it won some years ago. With a Python that is here. It's comparable to a pre-won calculator in fast Fourier transform using micro Python. And I participated in this project. Where there is an IoT experiment where all the sensors will have control of errors and circuits. So we have the responsibility to show for the community about 10 sensors, all of them controlling the details of the measurements. And all the development using micro controllers and S back by is done with a Python or micro Python. Thanks very much. Thank you very much.


Good afternoon. Welcome to the Envoy presentation. I'm going to be done from the Envoy. I'm based in the US. Today I'm going to do a presentation about Envoy. Before I introduce Envoy, I would like to first talk about Envoy physical. In the first half of 2015, it was the beginning of development. The founder of Envoy is like fire. The Envoy project was over-sourced in 2016. It shattered a lot of attention from the community, Google and IBM and other large companies all paid attention to this project. When I was in Google at the time, I also joined the development of Envoy CNCF. Since then, Envoy has made a lot of contributions to their community. And last year, Envoy became the third graduation project at CNCF. So that's the history. So I would like to now address why Envoy was developed. In the industry, in the micro-service networking, in many cases, multiple languages or infrastructures and protocols are used and also there are different levels of load balance and different levels of observability. But it's very difficult to get unified observability. For example, retry, circuit breaking, rate limiting and other distributed systems. Meanwhile, Envoy also needed to implement authentication and authorization. That means we need a per-language library in most of its code, but it's not very practical, unless this is multinational companies. And you only use two or three languages. And also Envoy is designated a team to manage the libraries and language framework. Otherwise, this is extremely difficult. And also debugging in micro-service is very difficult. It's highly probable that you won't fail. And also there's limited visibility into the components, such as hostages and load balancers, databases, cache, etc. And of course there are features such as circuit breaking and retry. These are multiple and partial implementations. It's very difficult to achieve. Also libraries are incredibly painful to upgrade. For example, if you have CVE, you need to upgrade for the applications and build them before upgrading in this code service. So Envoy is developed to address these issues. The main objective of Envoy is to make the network transparent to applications. And when network and application problems do occur, it should be easy to determine the source of the problem. And you can do this via Envoy. So applications don't have to pay attention to these features. And Envoy can help you to achieve all these functions, such as authorization and retry, etc. Now Envoy uses sidecar. Here each rectangle is here where net is part. On each part we will have a sidecar proxy. Under each application we can connect to the network and then communicate through sidecar proxy. So Envoy can do this order copy of the application. And then it can offer all those functions like this nation. These are the considerations when Envoy was designed. As we can see in the diagram, Envoy is an out-of-process architecture. It has an epsilon-2tcp filter. And it also has htpl7 filter architecture. And it's also designed with htp2 first. It has its own service to Envoy. And there are routine management including house checking and other load-balancing functions that other proxies don't support. It has as-in-class observability. Other stats are sent by Envoy, which means the format of the stats is unified. Another presentation at three o'clock. I will talk about more about observability in service mesh. This is another advantage of Envoy. Envoy is a universal data plane. We call this XDS API, which means Discover Service. Discover Service includes LDS, Listener Discover Service, CDS Buster Discover Service, and also Secret Discover. There are altogether seven or eight. And the latest one is a TDS and out-of-checking LTDS. This API is based on GIPC streaming. We use protocols to define these APIs and send them to Envoy, so GIPC. The advantage of this is when you extend your Envoy, you can avoid a pre-prosecutive. You can control the rest with your control plane. In the dynamic environment of cognitive, you don't need to manually restart different envoys so as to read the different configurations. This is the basic architecture of Envoy. In every Envoy, there are multiple workers. Each worker represents a process. Each worker has their own filters. The traffic is here. The connection is generated. Then they go through the filters, for example, L4L8 filters, and then it's connected with HTTP, ALC, and then it will go through the service route too and connect with the upstream connection pool. Envoy supports a lot of exposure. As mentioned before, there is L4L7 filter. Actually, Envoy itself works for small portion of Envoy code. Most of them are for L4L7 filters, for example. It can be a complete HTTP L4 level filter. The service filter is also another kind of filter at HTTP level. There are settings as filters. We also have logos and tracing and house tracker. For this, it's expandable. As we all know, for example, in Envoy, there are using filters and logos, which are also transfer software. Retro analysis can also be used by extension app. Since we open-sourced in 2016 in Asia, a lot of companies adopt Envoy. Here it's just a small amount of adopters. Actually, in China, a lot of companies, including Armin, that also adopt Envoy. Now, I would like to invite Mr. Tsing, who seems to have a lot of news about the use of Envoy in Envoy. First of all, I want to thank you for the introduction of Envoy and Leo Zhang for support in his early stage. His Chinese actually is not the same as what we used to speak. I would like to talk about how we use Envoy in NetEase. Because time is limited, I will just talk about our use case first. Internally, we have a service mesh, a macro-service spring work, and when we use Envoy, what kind of work we have done. And second, internally, we have some demands and we want to achieve through Envoy. And how can we expand and have the expansion of Envoy to meet our purpose? Internally, we have a department responsible for e-commerce. And they have the service mesh structure, but it's different from the whole existing service mesh. And they are using the engines. And they use console for service discovery. Engines, as you know, they simply plug in to extend. But they connect the console and they have a console plug to achieve service discovery. So, a service discovery cannot be healed by the business. But for their part, at that time, they do not have the service mesh concept and they are more practical. And they do not have clear demands, for example, for control board. And they do not have a configuration interface. And actually, based on the current status, we hope that we can use open source to combine with our internal resources. So, with that, we come up with a plan so we want to shift from engines, from current plan that is in the list. So, at the top there, this is data for each service they have a proxy and that they have the control board here that we use instead. And we adopt the version of 1.1 to 1.5 and with our test, we found some problems. For example, we do not use main component mix and so we create it here. And we mainly use component called pilot. And for business, previously the business side is on the cloud frame. And in terms of service, we need to connect to K-Buds. And for this plan, in terms of data listening, previously when we were connecting to service, we need to use engines and we need to use <IP_ADDRESS> to go to process because we want to shift from old plan to new plan. So, we do not want to have much change. At the invoice side, we want to have the configuration. As we said, we need to use proper configuration in the URL. We have a service name and we need to get the service cloud first. If you are familiar with engines, you know one way in engines, for example, e-write, we can get the service name, service cloud but actually we do not have this function here so we need to have the extension on the existing filter through the collection managing filter we made some minor changes and then we have a rewrite of host and pass. The data level change is not enough. We also use the control level. We need to cooperate at the control level. This is for the pilot from Instail. We need to have a configuration of RDS for the current scheme. For the e-commerce website, it is mainly on ATV protocol because invoice support listener so we only use one of the portal that is enough for us. This is a specific access route and first we have a URL to visit 127 route and directly point to <IP_ADDRESS> portal and then visit URL service path. Then we can get the service cloud and then through RDS, we can transfer to the cluster and the cluster is KBUS workload and it corresponded to a work point. Next I will talk about internal demand because for e-commerce, when they do have literally development, they have a lot of small environments because our service has been divided into around 300 microservice. If developers just change a few services when they do test, they do not want to deploy all these hundreds of thousands of services in their testing environment. So we have multi-environment governance internally. We have this kind of concept. So for every part, they only test the part they revised and they just upgrade the existing service and for the rest, they will use the original service for a lot of developers or QA. Every environment is different. So there is the problem of public using of environment. So when we connect to mesh at the proxy level through invoice or sidecar, how can we solve the problem? How do we do it? First, our scheme is that through control level we can have directed fruit through control level. At the development level, we have source labor to have some certain directions through this label. We can, through source label, we can point to upstream cluster. But for that scheme, it is suitable for the previous scenario but there are some white box here. The white box means for some services they do not have a correspondent part that have the same color. So if the color do not have a correspondent color service then they need to be downgraded. So it's not so feasible. So we come up with another plan. So from the slide you can see here. First of all for this scheme, we want to support L4 and L7. That means it can support ATP and TCP protocol. And for the coloring through Ingress, we can add some black and cookie to add the color for a specific service at the invoice side. They have inbound and outbound. Inbound and outbound are different. Inbound is at the website, at the entry level. Through cookie or header, they mark the color and inbound will get the color and through IDS and find the correspondent cluster. Then invoice, when transferred to upstream invoice, they are not using HTTP cookie. We are using H8 Proxy protocol. We do some extension. From the website picture you can see this is the principle. When we have the TCP connection and we will send PP package and there is a parameter here. It will state the attribute of the color. So between invoice through TCP protocol, they can identify the color attribute in outbound side. When they do the traffic transit, there are some problems that cannot be solved. So later I will explain why it cannot be solved. Here there is an example and there are two services. There are two services. The first person in four services, we will get the person information. From the slide you can see there are two different colors and the white means public version. Red and green correspond to the developer's version. The green want to get the information in the green database and the red want to get the database information from the lab to white. There are motions on problems to not be solved on outbound side. And there is no context but public. And on the outbound side. That means the color information from inbound, then we need the service for the instance. in the sense that the color of the work should be otherwise out and cannot get very professional color. And also, it is a natural color of your query or if it's a service called, if you have a C1, you need to have a center. Also, if you have your intranet, you can have a C1, you also need to present a federation. So that's a fundamental thing. Thank you, Ms. Witte. We are in introduction on the introduction of A&Y in the 90s. So the naturalization of the fabric is very unique because of the protection of the environment of seeing this kind of utilization. And it also allows the rewrite supported by the invoicing. So most of them can be implemented by doing this and use this function as a format. So this is the content of our presentations. Thank you for your listening. And if you would like to join any project related to A&Y, you're welcome to talk to me. And the project is also recruiting with your attention. Thank you. Thank you very much. Please take your time. Please take your time. Okay, thank you very much. to achieve low-high-endness and low-latency. CoreBase is a return-by-safe bus bus, and a lot of it has been used for a long time. And also there are some out-of-the-end should be to use the library for the NJ2TP and a lot of course supports have been used for a long time. I want to ask you about the performance of the material writing with the addition of raw material. Well, the performance of the material writing was the addition of raw material. There's no problem, but it's a trade-off between Amazon and other functions. You cannot have as many functions as possible without being able to try to make sure there's kind of almost deterrence and there's a wide support of all protocols. I'm wearing a coat right now. There's a team in Alibaba. That's working on this Alibaba. We're open to each other. Do you have many covers? Please send me an email. I can reach the person in Alibaba, and I'll have some future opportunities. Thank you. Any questions? Can we be more humble? Do you have a deeper-ever matching in-house form? Or do you have several... So, on the portal, can we have a different release? So, you need to do in-depth to get several parts of what you want to see. You need to do the matching before you know what you want to match with. So, you have different protocols to mention. This is a matching approach. You can compose the parts of this protocol and you know the function of the protocol and then it's given to the conversion. Now, we have this in the virtual, but it serves the TLS. You can understand the protocol. You can see the link, whether it's TLS or not. So, you can separate them and send them to different approaches. So, the different protocols in the protocol. Do you have a presentation? So, of course, you can do a presentation of the extension through a loaner. I don't know how difficult it is. It is too cold. If you have a loaner, you can also do an extension through a loaner. And currently, I would choose... What's the next step? Oh, what's the next step? You need six months to make some progress in the center.


Item Number – SCP-473 Object Class – Euclid Special Containment Procedures A 5 km area surrounding SCP-473 is off-limits to all personnel. Human testing in this range is prohibited without O5 approval. Above all, loss of human life within this 5 km area must be prevented. A further 20 km distance is to be secured by no less than two Foundation Combat Units at all times. Any unauthorized vessels entering this area are to be sunk, and their crew eliminated. Vessels approaching the site but remaining outside of the 20 km kill zone may be boarded and turned away with the use of Class A amnestics. Description – SCP-473 is a wrecked Spanish galleon, typical of those used in the early 16th century. It is resting on the ocean floor at coordinates expunged. SCP-473 was brought to the attention of the Foundation after the loss of a research vessel operated by P.A. University. A search and rescue team which approached SCP-473 reported audio anomalies like giggling and pleading for help. They reported voices in English, Spanish, and an unrecognized language. Agents embedded in the wreck immediately moved to cancel the search, declaring the crew and vessel lost. Note – though the wreck is designated SCP-473, anomalies present may be due to cargo within the wreck. Further investigation of this is advised against at this time. Proximity effects – phenomena encountered by ships approaching SCP-473 include disembodied voices which may have knowledge of Foundation personnel and operations and minor physical disturbances such as unidentified vibrations and impacts on the ship. Electrical disturbances are common, causing primary and emergency lighting to fail. This results in absolute darkness within a ship which, combined with persuasive voices created by SCP-473, causes extreme disorientation. Spatial in the area are advised to confirm the physical presence of anyone they are in communication with and to ignore any voices that have no discernible source. Periodic cries for help from the water, coming from the direction of SCP-473, are to be expected and ignored. Sharp objects and weapons are to be secured in locked containers, while within 20 kilometers of SCP-473. Addendum 1 – Interview SCP-473-B Interviewed J – Executive Officer of the Foundation vessel which identified and sonographed SCP-473. Interviewer – Dr. Halen, SCP-473 Project Lead Forward – A Foundation destroyer sailed within 500 meters of SCP-473 before retreating to a distance of 3 kilometers and sinking. Evacuation of the ship was successful, accepting the captain, but 16 hands were lost during the three hours the crew awaited rescue. Below is an interview with the highest ranked surviving officer. Begin log, April 17th, 2000 – Dr. Halen, our destroyer sank minutes after locating SCP-473. Why don't you start by explaining how your ship was damaged? XO – Well, I know what happened, just not how. As we got closer to the site, these voices got louder. Below decks started reporting some hard knocking against the hull. It got rough as we got close. The ship started to vibrate a bit, and some of the electronics shorted out. The captain ordered us to turn around, tried to get us out of there, but by the time we'd come about, they'd already started in on the bolts. Dr. Halen, could you explain, please? XO – It started to fall apart from the inside. Screws, bolts, nails in the damn furniture, it all started getting knocked out or unscrewed. Even some of the stuff welded in place. The voices got bad too, and the bastards were always so matter of fact and calm, even while they were rattling the ship all to hell and taking everything apart. One of them was talking about all the great things he could show me. Another was gibberish I couldn't make out, but she was pissed. We could all hear the voices, there were just no bodies to go with them. It got hard to tell which voices were our crew and which were the damn… whatever they were. Dr. Halen – When was the last time you saw Captain XO – He gave the order to turn around and told me to handle things on the bridge while he checked something below deck. I didn't know he was missing until after I gave the order to abandon ship, and everyone was in the rafts but him. God, if that had only been the end of it. We started rowing away from the wreck and we heard him yelling for help. It was far off, toward the shipwreck. He and I served together for years. We helped bring in SCP – I know it was him. I figured he'd gotten knocked overboard or something. And I gave the order for a raft to go get him. Watch them get close to the horizon, must have been two or three kilometers from the shipwreck when they just went under. No sound to it, like a kid's bobber getting pulled under by a fish on the line. I've seen men die, but I know I sent those guys someplace a lot worse. It wasn't long after that Daniel started whispering to me about what a bastard I was, how I sent them all to die for nothing. He said the only way to make it right was to jump out of the raft and join him. Maybe I would have too, if not for the other guys on my raft. We spent hours rowing, with our friends screaming for help behind us. Even when they were far behind us, they didn't stop whispering in our ears. My friend told me it was the most beautiful thing he'd ever seen. He never was religious, but he said that he'd found God. He said he only wanted me to see what God had shown him. We don't leave our people behind, we just, we don't. End log. Closing Statement Professor Boer and Associates present on a research vessel are confirmed to have been acquired by SCP-473. Recommend extreme measures be taken to prevent personnel and civilians from expiring in close proximity to SCP-473. Currently advise maintaining containment at present location due to the inherent danger of recovery and the threat of exponential strengthening through acquisition of class D subjects at any given site. Note, interview subject Jay's corpse was found in his quarters on April 24th, 2001. Suicide is suspected. A note nearby read, I shouldn't have left them. Testing of SCP-473 as a possible cognitohazard is recommended. Number 2 Continuing research has found that one professor word led the doomed university expedition to the site of SCP-473. Though his research notes appear to have been lost with him, his last outgoing email includes some context of his expedition. Sent. 115. 2000. Word. Samantha, you're right, the research papers are wordy and I could never put my opinion in them anyway. You already know that he led a small army south to Ecuador and eventually killed the high priest in charge of appeasing Supai, but it seems that he also captured his two daughters and arranged to have them sent back to Spain as examples of the indigenous population. Sick bastard, one of them is trophies or worse. Anyway, the ships manifest listed a number of cultural artifacts in the girl's personal belongings. On that list was an item that I think represented the God himself, and that is the real prize. The manifest lists all manner of gold and artifacts that the university would love to have, even if we don't hit the jackpot on this one. Still, I can't help but get excited about the prospect of bringing back the Incas on Holy Grail. All the best. PS. Let's keep this quiet. It'd be a disaster if someone beat us there.
