Because they couldnt hear the mother and she couldnt hear them. But in a bucket, it is like a Megaphone Itjust Amplifies the sound. They could hear her and she could hear them, so it was a win win situation. My work here is done. Except it is not. Now weve got Operation Mallard two we have indeed. She came back four weeks ago and started looking around my balcony, she moved to another planter which has lots of grasses in it and she has decided shes going to nest there. We now have 11 eggs and everything is fine and we have got about another week to go. Success, Operation Mallard, absolute success. Heres to the next one. Ian haslam, bbc news. Now its time for a look at the weather with louise lear. Best of the sunshine was certainly first thing, shower cloud developed in the letter stages of the morning, some quite heavy and slow moving, if you are out during the early evening, worth bearing in mind. Overnight showers tending to fade, under clearer skies we do it all again, temperatures are likely to fall close to orjust below freezing, blue tones denoting where we see frost first thing in rural areas. Chilly start to sunday, patchy mist easing away to sunny spells and scattered showers, once again these could be heavy with hail and thunder. All change for bank holiday monday, low pressure expected to come in off the atlantic, wet and windy weather arrives through northern ireland, gradually moving into southern scotland, north west england and wales, perhaps staying showery in the far north, and South East England should stay dry until the end of the afternoon. Top temperatures 7 12 celsius. Hello, this is bbc news. The headlines. A change in guidance on care homes from tuesday, residents in england will be able to visit relatives without having to self isolate when they return. India becomes the first country to record 400,00 coronavirus to record 400,000 Coronavirus Infections in a single day. Five people are arrested on suspicion of terror offences, including a 16 year old boy, as Police Target three locations across the uk. New Research Finds that around 1,000 rivers are the source of the majority of Plastic Waste in the ocean. And theres a warning that most of the uks summer Music Festivals could be called off because they cant get Covid Cancellation insurance. Now its time for click. This week how to uncover deadly secrets online. The secret codes attracting more women into cybersecurity. And tenet, the oscar winning secrets of making time go backwards. Audio tracks backwards. Welcome to click. We all know how easy it is to fake things online these days not even photos, voices or videos are safe, as we well know, right . Yes, weve worn fake clothes, we have faked our voices with software. Ive even been entirely faked with a virtual me although i am convinced that she looked ten years older. I Whole Heartedly agree. Later in the programme, were going to see the hollywood version of this, when we look behind the scenes at the film, tenet. Spoiler alert it wasnt all real. But these days, you dont need a big budget to do this. Just think of those Zoom Backgrounds that weve all been looking at. Admittedly, the edges of your hair do often give the game away, but these pictures are pretty good, a lot better than we would have imagined they could be five years ago. Harp glissando. So, check out the next advancements. This is where zoom can put meeting participants into a meeting room a real one thats not real, although i think something has gone wrong with the sizing here, dont you my seat� s way too low and youre far too small. Theres a variety of scenes. Do you want to meet me for a coffee . Look, here we are in a coffee shop. Yeah i will have a latte, please. Id say this is cute, but does it make you feel like were in the same room, really . No, i still feel like were on a zoom call. Maybe this is one for the audience, rather than the participants. But while there is plenty of fakery around, the truth is out there, as a certain fox once said, and there are some people who know where to look. The internet is just such a vast place, and like theres so much out there thats just public, so many ways that information can be manipulated. And even, like, political news can be manipulated in someone� s favour, so that is where i think open Source Intelligence is useful. 18 year old Computer Science Student Kenyon Lee has gone viral on tiktok by using so called open Source Intelligence, collecting and analysing publicly available data. His main trick. He guesses peoples exact height by finding other objects in the same shot and tracking down their exact dimensions. Woman how tall is spencer . Now, kenyon did do this test on a video of me that he found online and well come back to that later. Mainly on account of it being the most embarrassing video ive ever posted online. But we have some serious stuff to talk about first. But trust me on this. There are groups of people out there who are using open Source Intelligence techniques to do much more serious detective work. These are Anatoliy Chepiga and alexander mishkin, widely believed to have been responsible for the Salisbury Poisonings in 2018. This week, a collective of open Source Intelligence investigators revealed theyd also managed to link these two men to the bombing of a czech Ammunition Depot four years previously. That collective is bellingcat, and weve met its founder, eliot higgins, before. In 2014, it was just him, but now he has a foundation in the netherlands, 20 staff members, and a growing network of volunteers all across the world. I caught up with eliot again recently and he told me that flight logs of chepiga and mishkins trip to the uk in 2018 were revealed by a russian news site, and that showed that their Passport Numbers were only a few digits apart, which was to say the least, unusual. That caught the interest of bellingcat, in particular our investigator christo grozev. So, christo looked at these databases and discovered these two individuals didnt exist before 2012. Theyjust popped into existence in these databases in 2013, which was suspicious. He then approached basically an Information Broker who sold him these domestic passport registration documents, and stamped on them was the number of the Russian Ministry of defence. And it became clear they were not ordinary people, that these appeared to be russian intelligence officers. Bellingcat� s investigation didnt end there. Their evidence showed that scientists linked to the 2018 poisonings were following russian opposition leader, Alexei Navalny on 40 separate trips in 2020. That includes the journey where he was poisoned. It seems what we stumbled on with the skripal story, is this entire kind of network of russian assassinations using nerve agents. And that sounds completely insane, but, you know, we have the receipts. We have the phone records. We have everything to show this is happening. And this is basically unique to russia because russia has this massive amount of corruption where data, phone records, even if they are spies are freely available to anyone that does a bit of googling. What tools or software do you or your investigators use when youre looking at photographs and trying to work out where theyve been taken and when you are Tracking Information back across the internet . We have an online tool box, which is basically loads of links that anyone can go and look at and use them themselves. Probably one of the most powerful tools is google, google earth, google streetview. They are extremely useful. Resources now allow you to track aircraft, like flightradar, marine traffic allowing you to track vessels. Photographs and videos can now very convincingly be doctored, does that cause you a problem, or is that a new investigative stream for you 7 you have concern about deep fakes and there is concern on immediate social media reactions about things being retweeted. We approach stuff as evidence, so when we look at that kind of thing, we say, ok, here is a video of tom cruise playing golf. Can we find out the golf course . Or if someone is giving a speech, it is going to be from a longer piece of media. People dont give two minutes 20 seconds speeches. They are generally longer. So we look for that original footage. We look at the account who shared it. Is it shared by an official News Organisation . We look at the account behind it. Has it been shared before and where has that stuff been . You look at the different dimensions of that video both inside the video and how it has been shared and propagated online. Absolutely fascinating stuff. That was elliott higgins. I cannot put this off any longer. Time to go back to mr lee. You remember him . Time to go back to kenyon. The tiktok person. The problem is. The video he chose was my Ice Bucket Challenge from years ago which, if you have not seen, well, you are probably one of the lucky ones. I have seen it. I cant un see it. Ijust cant get enough of you. I was trying to raise money for a good cause so i decided to go full outrageous and i kind of forgot that the internet never forgets. Ok, here it comes. I decided to look at the Ice Bucket Challenge. I overlapped these two frames and marked the top of his head and scaled his height. This translate to. There was a point to all of this. Did he get your height right . He said 174. 75. Lets have a look. Oh, wow, 175 not bad, not bad at all. Not bad considering he did that from the dimensions of a bucket. Yeah, good thing he didnt use a 3. 5 inch floppy disk hello, and welcome to the week in tech. It was the weak us ridesharing firm lyft was sold to toyota. For 550 million. Tiktok said it would open a european transparency and Accountability Centre in ireland. The announcement followed concerns over how the chinese Social Media Giant serves its young users. The first Triple Drop Drone Hit the skies. This Electric Device can carry and deliver three separate loads although it can only stay in the airfor a maximum of 90 minutes. Two College Engineers Won Awards for their invention. That was an mit award, the green weevil. This remote controlled robot helps farmers stay safe while it levels and distribute the crop. It can dig itself out of grain as well. Grain weevil. This autonomous arm uses al to identify nearby apples, leaves and branches, all so it can plan the path for its pneumatic suction plucker. It can pick and deposit an apple in as few as seven seconds how do you like them apples . this is the huawei 2, the third iteration of its Folding Phone and easily the best yet. The Folding Screen is now protected inside the phone, which makes a lot of sense. It has been a pleasure over the last few years to be able to try out so many of these Folding Phones and see this new category of devices emerge and all the manufacturers have had such different approaches. Huaweis was always unusual because it wrapped the folding display outside the device, which looked cool, but it did leave the display vulnerable. This time they are taking a leaf out of samsung. There is a secondary display on the outside of the device. Actually, they have taken a few leaves out of samsungs book as well this time. This is very similar to the galaxy z fold2. To the speaker, the camera bunk and the chunky edge. I thought Folding Phones might be the end of every phone looking the same but here we are. It is a much better design. The screen snaps into place. And it does leave a gap, which is a big improvement over samsungs design. This is a big improvement. This is the first one of these id feel comfortable enough to throw in my gym bag like a regular telephone. Another fantastic bit of engineering. When i first started using it, it felt really comfortable in my hand. I couldnt quite put my finger on why. Ive been very scared of dropping these Folding Phones because they are typically very expensive and fragile, but with this one, i neverfelt like i was going to drop it. It sat comfortably in my hand and this is why, the phone is wedge shaped, which moves the centre of gravity closer into your right hand, so when youre holding it here, there is less weight over here. It weighs 300g, more than a regular phone, but because of this, it does not feel like it. I also like the outside display because, when it is closed, it is a full size regular phone with no compromise. You get pretty much the same experience as you would with a regular smart phone, including the great camera array. Great stuff. That was chris fox. The secret services have always been. Secret. But it seems that some things in the world in espionage a change. M15 has just joined instagram. But other areas have not. For example, the number of women working in the field stands at just 16 . But a School Competition is hoping to change that. To see the role that women have taken over the years in cybersecurity, i first took a trip back in time to look at some pretty special computers and the coders that used them. Im here, at the National Museum of computing at Bletchley Park, a place full of computers and memories, not least of the world war ii codebreaking. Today, it is largely associated with the man who broke the previously unbreakable german code. Alan turing. His efforts gave the allies the edge. 63 of those working out of Bletchley Park were women, many of them working on the world famous colossus. The Job Description they gave to women were different to those given to men so, if you go and look at the paper records, you will find that women are described as typists or translators or clerical staff. And that disguises what they were actually doing and this is because men were on a different pay scale so the Code Breakers had different job titles to women, who were on a different pay scale, but it did not tell you anything about the quality of what they were doing. What should alan turings legacy be . Ive been writing a book that is trying to get away from the sepia tinted view. Of what he was and what he should stand for. He was always looking at the future, he was sort of like almost Science Fiction and thinking about these Amazing Things like machine learning, which was obviously completely impossible in the late 1940s. While many women were employed in Code Breaking in the 1940s, the imbalance in numbers between Men And Women In Cybersecurity Today is huge. But to help put things right. The National Cybersecurity centres cyberfirst girls competition is trying to find the next generation of female codebreakers. It involves solving puzzles i to do with coding and logic. Cryptography, cybersecurity networking. And its really fun. Promotes the idea that girls can code. Its officially competition day and i am very excited. We will be looking at the topics now. J in the semifinals we could see the leaderboard, and i remember everyone was rushing to do more challenges. 12 and 13 year old girls from across the uk have been competing in this years challenge, which has moved online. You may think that is where it should be, anyway, but it is a collaborative and creative process. We need to succeed at our mission to keep the uk safe, to keep people in the uk safe to work and live online. And we need all kinds of people to do that, just to represent the society we are working for, but also to get all of these different perspectives. And girls sometimes bring a different perspective. And some would argue that women have a real knack for it. Women are good at linguistics, i which makes them irreplaceable at any natural language processing services. They are also very attentive j to detail and good at paying pattern recognition, and overall, patience, which are requirements for any science related jobs. | with an abundance of all those qualities, this years contenders are certainly feeling the pressure. Having battled their way through ethical hacking, cryptography, decoding, logic tasks and much more. While waiting to find out who wins this year, i spoke to an ex finalist, who is now studying cybersecurity at university. And because she is set on a career in the field afterwards, we had to keep her identity under wraps. I think definitely there is pressure to do well. I had to prove myself because im a girl, just initially a leap, and then i was hooked to. You see all these women who are inspirational and you want to live up to them and you dont want to let all the other women down and you want to help inspire the young people yourself. Back to the competition, and The Moment Of Truth is upon us. I really enjoyed the logical coding ones, but i also really enjoyed cybersecurity, because it required you to think in different ways and use different methods of hacking. It really makes you think of how easy it actually. Is to access other peoples data and how important i it is to keep your computer safe. I i had to connect a circuit board, and then once you covered your hand, it would start beeping. We figured out those Beeping Noises were morse code, like dots and dashes, and we wrote those down and found out what those were. In the cryptography section, if you have. Nneded to send, like, a coded message to someone, i learnt a lot of different types of codes. I think a cybersecurityjob is now an option for me. Congratulations to the girls at highgate, wow what an inspiring story one of the few films i got to see the cinema last year was tenet, as a massive geek, i absolutely loved it. And you watched something twice . The second time, with subtitles, which i recommend, because it helps you understand what on earth is going on. This is a film where half of the story is going forwards and half the story is going backwards at the same time, in the same scene maybe it is no surprise that it won the oscar for best Visual Effects . Yeah, and if you did see it, and you wondered how they got cars crashing and buildings exploding in both directions at the same time, well, the answer may surprise you. Inversion. Aim and pull the trigger. You arent shooting the bullet. Youre catching it. Whoa. Doing Visual Effects for a Christopher Nolan film, i imagine is different from the majority of Big Budget Hollywood Films with l a lot of Visual Effects. Because his approach is very much about finding ways to film practical elements. Wherever possible, we wanted to find ways of filming real components and mixing it up a little bit so they felt very. Real in the real world, but still had that slightly odd kind of thing, it wasnt just a case of filming forwards scenes and reversing them, l it was more than that. More interesting and more complicated. A good example was when we have cars pulling away quickly and they| are in an inverted car. You would expect the wheels to spin or throw some gravel out backwards. What we did for those, we found a way of dragging a car backwards while its wheels were spinning forwards, so we threw dirt out backwards, so was in the wrong direction. L so we inverted the thing, all the way, sucking dust| back into the wheels. That was the sort of approach where we found a practical. Real world event and then just sort of turned its on its head i a little bit so it felt real but wrong. You want to crash a plane . Not from the air, dont be so dramatic. Well, how big a plane . That part is a little dramatic. The plane crashing into a building, talking to people since the film came out, everyone assumes that. That is largely cg, or must be, l components of that must be cg. But in reality, that i was actually achieved as a practical event, where we used a full size, real plane, and built a set. And all of the Pyro Explosions and everything is in the shot for real. There were Visual Effects involved in that we had l to clean out the tow ropes and added jet blast to the engines and cgi trees to be burnt, but really the vast majority, the chunk of that shot was in camera, and so it is i kind of turning it on its head again a little bit in that people assume it is cg| or there are some major components of it that are cg. But it isnt. The end scene in the film contains a lot of big explosion events, and there are. Combinations of forwards and backwards explosions. You cant train an explosion to be backwards. So we had to had one. And a half of that shot. We certainly did that a lot for. Where there is the minefield i sequence and people in trucks running up and down the hill and mines going off, we used a combination of practical shot elements, but also cg explosions, which had to incidentally match exactly the practical ones because they were right next to each other. Another major event in The Battle Scene was where a building is simultaneously. Blown up by an inverted group of people and a normal group of | people, so it is simultaneously| exploding and imploding. So, we built two large or they were one third scale ten storey buildings, i two matching buildings, and we filmed each of them from a matching camera angle, and we blew one up at the top and one at the bottom. And then we could reverse the film and composites the two together, reverse one of the films and composite the two together, so this building had a sort of simultaneous exploding and imploding event. This reversing the flow of time. Doesnt us being here now mean it never happened . Talks backwards. 0k i think spencer has gotten a bit carried away. As ever, i think you can find us on the right order on social media, youtube, and instagram on bbc click. Talks backwards. Ill leave him to it. Thanks for watching, and well see you soon talks backwards.
