11:40 pm
and the vice-rector for academic work and internationalization of education at the belarusian state university, candidate of technical sciences, viktor pavlovich, hello, hello, a question, as a candidate of technical sciences, tell me, squares, necessarily on the sides, large squares, what is it? we all know that in the digital sphere everyone operates with zeros and ones, this is any code, as a result , a set of zeros and ones is transformed, so the qr code contains a set of zeros and ones. black and white squares, they just denote zeros and ones, when the scanner reads them, it turns out to be a code, and what are these squares in the corners for? everything is quite simple, in fact, you can draw a bunch of squares, but the scanner must understand that this is a qr code, that's why it sees these three markers, these three squares, by them it determines, firstly, how to read there from above, down, down, up, left, right or vice versa, it understands the boundaries of this qr code, that's why it can be made large, small, at an angle read. because the scanner already determines
11:41 pm
the boundaries of the qr code and then begins reading this code. and why was a square chosen as a universal form? and it is easiest to read in fact, that is, if, for example, a barcode requires a special scanner, then for a qr code an ordinary phone is enough to read it. and squares, they are much easier to read, namely, with any camera. listen, well, ones and zeros, well, the information is encoded in words there, how is all this correct, in fact. there are a bunch of different tools, how to do it, qr code is used in many places, as a rule, it is, for example, the name of some domain, some payment method, payment confirmation there and so on, so - let's say, when you have some information, you encode it with special tools and get a barcode, it can be really different, you can even put a square with some logo in the center to enhance some visual effect, and the qr code will not suffer from this, it will be readable and it will be possible to decipher it, since we are talking about the qr code will not be damaged, but if something
11:42 pm
is damaged somewhere, it will not be read, or there is some limit, you can damage, i don’t know, half, 30%. yes, the qr code, in fact, seems to be just a set of simple squares, but in fact this is a very serious technological phenomenon, because even if up to 30% of the qr code is damaged, it will be readable, there are special algorithms, special mechanisms to read the qr code, even with a fairly significant...
11:43 pm
you can add another square, like this small, if you look, there is another small square in the lower right corner, thanks to it you can look at different angles to determine exactly at what angle the camera is relative to the qr code, and this allows you to read it in any state and get reliable information, i did a little more preparation, qr codes can be static and dynamic, tell me what the difference is, well, except for the name and the concept that static is static, dynamics is dynamics, static, i think it is quite clear. that is, there certain information is protected, which is constantly unchanged, for example, you come to a museum, read it and some page with information opens for you, this is all clear, but the dynamic one is more interesting, it is formed for certain operations, for example, for payment, and its lifespan can be from several minutes to several days, why is this done, for example, you need to pay, you are issued an invoice for payment, you pay and as soon as confirmation of payment comes, this code can change, this is also quite a convenient tool for implementing it.
11:44 pm
was one of the developers of this technology, suggested that we implement it, we had such a technology implemented in all our public catering points for the convenience of payment, implementation of new technologies in the production part of our university. you said that a qr code can be for several days, or maybe for years, do qr codes have an expiration date? statically no, it all depends on the creator of this qr code, that is, please, created information there sewed it will be maybe... yes, to what, to the fact that qr is not
11:45 pm
the only format of two-dimensional codes, there are several options, tell us, and which ones are used in which areas? yes, indeed, there are various options for name-dimensional coding, also data matrix, adt code, pdf1417 others, all this direction does not stand still, new new tasks arise that need to be solved, it is clear that the qr code has shown its effectiveness, but nevertheless for some highly specialized tasks it is desirable to strengthen it somewhere, somewhere improve, that's why...
11:46 pm
some of your proposed solutions, you've already mentioned datamatrix, my colleagues went to the store and looked at how it all works, let's take a look too, you've definitely seen such stickers on products in stores, this is a data matrix code, a digital brother of a qr code, it is more focused on industrial production, but in everyday life it is an excellent assistant. all information about the product, manufacturer, composition, expiration date and other characteristics is sewn into this small square, it can be read using a mobile phone applications, called an electronic sign, by the way, a belarusian development, even a cow is written, the origin of the raw materials. the mobile application electronic sign is a service to
11:47 pm
help consumers, it was created so that everyone could choose high-quality and legal goods for themselves. and they counterfeit shoes, and milk, and fish, us. belarusian brands are good, that is , well-known, well-known in belarus in russia, so in principle belarusian products, well, such a risk zone, belarusian coca-cola is counterfeited, and quite decently, condensed milk, because it is made there using unique technologies, from whole milk, in belarus there is only one such enterprise, that is, in the post-soviet space it is truly such a unique product, the mobile service is free, it is simply installed and linked to a phone number, if the buyer sees on... or discovers a fake, he can report it to the regulatory authorities directly in the application, in addition to the public control function, the data from the application helps to understand the information that is written in small print on the label or for some reason it got worn out, and this is really a way out, for example, a life situation, you check, yes
11:48 pm
, their products are good, but the whole point is that they put this very thing on the blue so cleverly that you can’t always figure it out. so in order to get rid of this, there is a special application, you can scan this two-dimensional code to make sure that the expiration date will expire in 22 days. today in the country about thirty product groups are labeled, these are dairy products, tea, coffee, drinks and juices, laptops, mobile phones, shoes, tires, light industry goods, and this list is constantly expanding, in addition, a pilot project is being carried out on marking jewelry, today you can make sure that ... from the russian federation, for example, for this you can take a russian product and read it with a mobile application to make sure that everything is fine with it, it is in legal circulation and of high quality, a reasonable question,
11:49 pm
why is it the data matrix that is used in marking, this is a technological code, it is assigned not to the party about each unit goods, a unique identifier is difficult to counterfeit, can be read when damaged and, most importantly , can be microscopic, and can contain more information in a small area than other codes. the barcode that is applied to the pack identifies the product itself, as a unit, and the two-dimensional code that is presented here contains a barcode, a unique serial number that allows identifying each unit, that is, for example, these two packs of tea can be packaged at different times and gt on... will not tell about it, here directly the identification tool, which is presented here, will indicate that this tea was packaged, for example, in the twentieth year, and this in the twenty-second. already in the summer of 2025, the matrix date will displace the usual barcode at the checkout, during purchases, the scanner will read the two-dimensional code, thus
11:50 pm
the goods will be individually withdrawn from circulation in retail trade. this is a new level of protection against counterfeiting. the application will record that the goods have already been purchased for it, there is a receipt, which means that it can be re-... this is the science project nearby, today we study qr codes that's what's ahead. education, what's in interactive learning trends. be careful with quishen, when the picture can become malicious. in the digital dimension, how to revive archival content in search of history, we're going to vitebsk. only for our tv viewers, we choose the best routes. it's hard to believe that we are now exactly where the city of minsk once began. where are we going? first,
11:51 pm
safety, and you tell me where, you're driving. next stop - astersov. let's go! bye! and we're heading off on an exciting journey travel around our country. how? this memorial complex was created. the boys of our school, a searcher-local historian, a teacher of history and geography, brought a note from the newspaper, which described the battle on the nameless height, and the settlements of our area were indicated. alexander, i understand that your team selection as such does not exist, but if i wanted. i was taken, well, naturally, without problems. discover belarus together with the tv channel
11:52 pm
belarus 24. guys, whose erudition would be the envy of any adult. remembering school program, together with the project participants, i know. yulia, you have the floor. eleventh-graders burst into our intellectual air, and it's cool that they decided to pump up their knowledge before an important stage in their lives. is it true that the official language of new caledonia is english? history is not my favorite subject, that's probably why. new caledonia is a poisonous state, if i'm not mistaken, it is located in the ocean. whose wife was barbara rodivil? segismund ii had three wives, the first and third were habsburg sisters, the second one was barbara radivil. artem, did you answer option a? well, yes, what were you sure about? in the answer, well, what were you guided by? clearly not a history textbook, in front of you is a poster for a film about a mathematician and
11:53 pm
cryptographer who created a decryption machine in 1939, what was his name? watch on the belarus 24 tv channel . for those who have just joined us, i'll tell you, this is the science nearby project, today we are analyzing a qr code on a pixel, our guest is a projector on educational work, internationalization of education belarusian state university, candidate of technical sciences viktor kochin. viktor pavlovich, well, qr codes could not bypass the education sector, so let's take the example of the belarusian state university, where all this has already been implemented and works, we, as the leader, introduce all any new trends into our educational scientific process, but the qr code
11:54 pm
is more of an assistant for us, because our main activity is of course education, but nevertheless we try, after all, young people come, they sit in their phones and for them all these technologies are already close, that is, they do not need study them, and of course we have to go a lot over time, for example, we create various guides using qr codes, information about faculties, about specialties, now it is much easier to scan to see, now it makes no sense to print. some booklets, distribute them there, some to carry out work here, it is easier to hang a qr code somewhere and it will be clear, again, if there are some conferences here, we form a qr code for connecting to a wi-fi network, we try to use it as much as possible, i already talked about using qr codes today for payment in our canteens, this is the innovation that we also implemented at our place, in the future i think this direction will develop and we will monitor what is happening in the world to implement more and more new technologies, including in the field.
11:55 pm
study, and i am sure that in the heads of our series all this guys, of course, they are young scientists, young guys, more and more new ideas are born, i believe in them, and i am sure that in the future we will hear about them, we will come up with something interesting, it is even difficult to imagine that they can still be young people, they are very creative, well then the question about the future, qr code - that's it or something
11:56 pm
will happen next, you can assume today, oh, the world is changing so much now that now... what will happen in 5 years is very complicated, so dynamic, who could have imagined 5 years ago the development of science and technology that exists now, and what will happen in 5 years is already quite difficult to even predict, in this regard i like to listen to young people, how they fantasize, how they generate ideas and when they really live by it, that's it it is really very interesting for me, because besides everything else, i also teach children and i enjoy communicating with young guys who are really very smart and very motivated.
11:57 pm
whether there are some barriers, of course, there are barriers, information security is an extremely relevant area, now it is probably number one, and specialists in this area, they are now the most in demand, what is the reason for this, there really are a lot of scammers, the entire digital sphere, it is permeated with various technologies, of course, there is a temptation to counterfeit something, steal, sell it there and so on, so the qr code is also not on the sidelines here, but the main reason for these frauds is the human factor. you always need to watch where you scan, you don’t need to scan everything, you need to look so that these are really verified stands, let’s say you go to a museum, there you need to see that this is really a qr code , not just some kind of pasted somewhere incomprehensible and how, but it really is belongs to that museum and so on and so forth, here you just need to really get information, watch, analyze, this is the most important thing, because there will always be
11:58 pm
scammers trying to deceive everyone, steal and so on, we live in a digital world, alas. you, of course, literally explained on the fingers, well , in fact, not the simplest topic, thank you , thank you very much for coming, that's how good luck only to good, smart students, thank you, the qr code has also become a kind of
11:59 pm
guide between man and history, my colleagues could not resist and went on a trip in time. on the line is ancient vitebsk and bailiffs. honor and respect of all living in the village or in the city, a combination of high intelligence, measuredness, but also lightning-fast reaction in actions. this is how you can briefly describe the profession, which in the territory of the vitebsk region and the polotsk district, these lands are called the cradle of belarusian statehood, originated more than 4.5 centuries ago. then in the 15th century, their on...
12:00 am
bailiff, somewhere investigation of the court, bailiff, notary notarial functions performed, here we are everything was laid out, shown, accessible. in all forms. research work on data search turned into a unique exhibition called bailiff on the pages of history. here is described the path of the formation of the profession decade by decade, century by
12:01 am
century. all historical papers that are presented, archival originals of documents. different years had different legislative systems. and we all know very well and are proud that already in the 16th century on the territory of belarus there was a system that was unique for europe. level of execution of court decisions. already with the second edition of the statute of the grand duchy of lithuania, the activities of the bailiff were described, formalized and regulated. the bailiffs then still performed the work of a notary and even went to
12:02 am
the area as police officers. by the way, how their uniform changed at the exhibition can also be traced. and now without leaving home. archival documents, portraits of bailiffs from the past, photos of professional attributes will appear on your mobile phone in one click, thanks, of course, to qr codes. exhibition in mobile format was. was created this year, the project was created with the support of polotsk state university, directly polotsk state university assisted us in digitizing, the presented exhibition, here are presented six periods, all of them contain qr codes link to polotsk, to the website of polotsk state university. if you still prefer to get acquainted with the new in offline mode. the exhibition can be viewed in vitebsk, in the building of the department of compulsory execution of the main the vitebsk region justice department, and if you still prefer the mobile version, then the qr codes are already posted on the website of the main
12:03 am
justice department of the vitebsk region. for convenience, all information is divided into six parts of historical stages, each of them has its own qr code, a few seconds and you get into the past, getting to know it in literally an hour, although ... this path to the formation of the profession of a bailiff took almost half a thousand years, there are many associations with the qr code, something similar to a crossword puzzle, someone even finds a resemblance to a photo from space, but this is about the external, if we talk about functionality, i would compare the qr code with a door, it opens access to a new space, and we ourselves can create it, as they say now? surf the internet, generating a personal qr code is really not difficult in principle, all because in this topic science is nearby.

12:06 am
from ... hundreds of dreams were passed on, and here are all this as if i would correct in my works, here are our flags, dzerablechy, glad, here are these the legend itself, this is how it was written, already about 50 years ago, because i was a trotter in my childhood, because i loved it from my childhood, i wanted
12:07 am
to become an artist. kind of clubs, here are the first flocks, clubs, the club of the udzyalians, these are the tsyalyats such vuskiya growing white, because there are eumens, they are glad, lads, here they are and now they are living, in the lads they are all bald, was given and they would be so reasonable, that's why the geats apostled likhvan, like everyone else... i think about every family, like him. kashevskiy udzial's horns, because he doesn't step with dears, so persistent, practical, so, and at the same time and their dzetsi is like that, that ’s my face, because their nature is like that, yes, that’s how it is in every dzetsi, i say, such are the ears of the cossacks, no bread , no kalatush zvaryts, poor.
12:09 am
he himself is a tulabian, for he is a lad, a young man, he has disbanded everyone, and at the same time this is a joy for us to live, to be related, to marry and to remember, three periods of life for each of us, so we must this period of our life, each of us must well, here you go, then he will be a happy man. i'm collecting all the expanses since childhood, only there were no buildings, there was nothing, and the club was built in the 50s, the first clubs were built, until 63 years old...
