many and scotland. temperatures for many in the west holding onto double figures. the band of rain and wind sweeps eastwards throughout monday. a little bit brighter across scotla nd a little bit brighter across scotland and northern ireland with some heavy showers but the rest of the week will stay unsettled and often windy. hello this is bbc news. the headlines: writing in two sunday newspapers,

borisjohnson urges the eu to show that it's willing to compromise with the uk on a brexit deal. police in hong kong charge protestors with batons and use tear gas once again — a day after the government bring in emergency legislation banning the use of face—masks. roman catholic bishops are gathering at the vatican this morning, as the pope opens a three—week synod focusing on the amazon region of latin america. more british success at the world athletics championships in doha — as both the men and women's 100 metre relay teams win silver medals. now on bbc news, it's time for click. this week, microsoft boss satya nadella uncovering state—led internet manipulation. satya nadella uncovering state—led and abominable animation. satya nadella uncovering state—led look at him. he's a yeti.

some call it fake news, some call it disinformation, online manipulation, or even information warfare. the tech giants call it coordinated inauthentic activity. false news articles on facebook, bots amplifying questionable opinions on twitter. what we now know is that nation states have and are weaponising these techniques to their own ends; russia to interfere with elections, china to spread disinformation. but there is one place which hasn't been associated with deliberate

disinformation recently. and that's wikipedia. it's the largest collection of human knowledge ever created, arguably the first digital wonder of the world, the font of all internet knowledge. it has nearly six million pages, with a staggering 18 billion page views every month, and it was created in the best spirit of the internet. transparent, nonprofit making, and open for everyone to read and edit. we may have been naive to believe everything that we read on facebook. but surely wikipedia's army of volunteer editors and fact checkers can keep disinformation under control. well, now click investigates evidence of a possible strategy by the chinese state to manipulate wikipedia for its own propaganda aims. here's carl miller. edit wars stemming from genuine differences of opinion have been part and parcel of wikipedia

since the very beginning. so is vandalism, which is why wikipedia has created ways to combat it, with a mixture of bots and editors with special powers patrolling the platform day and night. but what's to stop people or even worse, governments and regimes, from manipulating the site for their own ends? it's something that's bothered me instinctively for over a year now. what first got me on this track were these two documents. both initially written in chinese, but we had them translated into english. one is written by a chinese official. the other was written by a couple of academics. they present a playbook for how wikipedia operates — strategies to influence the platform and argue there are strong reasons for doing so. strategies such as creating teams to edit on the platform, and cultivating opinion leaders, and using different rhetoric to change and rebalance china's image. both papers stress what a vital source of information wikipedia is for the people around the world

who read it, but complain that it contains misleading and prejudiced content against china's national and governmental image. but this isn'tjust a problem to be confronted by volunteers, in the words of one of the papers, the chinese state should act proactively too. one of the places mentioned is taiwan, situated to the south east of mainland china. the island is regarded by china as a renegade province, but many in taiwan dispute this understanding. so if a war on wikipedia is going to be fought anywhere, it's going to be there. armed with this information, i went to meet some taiwanese wikipedians at a hackathon in the capital city taipei. this is a very crazy year. yeah, a lot of taiwanese. wikipedian's attack and left. later on, they pointed me to some examples of the kind of manipulation they say is happening on wikipedia on chinese—related issues.

one concerns the very nature of taiwan itself; is it an independent nation or in fact a province of china? they repeating editing power articles on the english and chinese wikipedia, and they wipe out the taiwan open and they wipe out the taiwan opinion and just keep the china one. repeating itself, taiwan is part of china, one of the provinces of china. it's not like outright vandalism it's just like pruning the language. shifting the language to kind of go from one thing to another. how long will it be been going on for? years. years? and examples kept flowing, such as the senkaku islands, a disputed territory actually, but which for a while was china's inherent territory, at least in mandarin on the wiki data pages. although there are elected office holders with powers to take down or lock articles, some of taiwan's wikipedians fear

that these elections for these positions have been targeted amidst a general rising atmosphere of intimidation. so taiwanese wikipedians or people that voice anti—chinese opinions on wikipedia, they get attacked and trolled and abused and docs on wikipedia regularly attacked. what does wikimedia global think of all of this? is it because they're american and theyjust don't know the word? the hostile word. it's lost in translations. heather ford has researched political edits on wikipedia. whenever you have a group of motivated and well—resourced people who are taking a particular political line on wikipedia articles, that they can very easily overwhelm the volunteer efforts of wikipedia. our own investigation has managed to find nearly 1,600 times where, across 20 topics or so, wikipedia was changed to broadly

bring its content closer to the chinese government's line. i tracked down an expert on chinese social media and cybersecurity to give me a broader sense of how this all fitted in. telling the china story has become a really important concept and idea in the last couple of years in chinese politics. they think that the rest of the world has wrong views of them, misunderstands them, and in order to do good politics for them, they need to project a good image. looking at the articles on the recent protests in hong kong, the english and chinese versions are completely different from one another. this time, the edit war between a couple of editors saw 52 changes in the space of a single day, arguing over the goals of the protesters, and small language tweaks constantly such as whether they were protesters or, infact, rioters. academic shirley yu thinks that

trying to tell your story is really the natural behaviour for any up and coming superpower. china feels like a hong kong issue is my issue. "i own the issue therefore i own the voices on the issue "and i should own the verdicts on the issues." everything that china is primarily interested in and concerned about is to defend its political positions. it's all about china. the anglo—saxon world's primarily over the foreign debt over the past four decades has really framed the china story and the interpretation of china based on a western follow article interpretation of china based on a western philosophy in the political economic framework. and i think today china does owe the world a china story told by itself and from a china's perspective. i think it's not only chinese privilege is really a responsibility. we really don't know how widespread all this is across the vast expanse of wikipedia's multilingual entries. and it is impossible for us to verify whether the chinese government really is ultimately

responsible for any of it. absolutely conceivable that you know like people from the diaspora, you know, patriotic chinese are editing these wikipedia entries. but to say that is also to ignore that larger no structural coordinated strategy of the government has to manipulate these platforms. heather ford isn't surprised at all to see the states might be getting involved. i'm surprised it's taken this long actually. i mean, when you consider the fact that wikipedia is not only the fifth most popular website in the world, when you ask siri or you ask google questions now using the knowledge engine is from wikipedia. so it is a prioritised source of knowledge and facts about the world. and if you can influence that, then you are influencing how people are understanding and perceiving what the truth is.

that is fascinating stuff. and carl's with me now in our underground bunker somewhere. carl, how sure can we be that these manipulations are being done under instruction from the chinese state? and also how sure can we be that it is really widespread? we know there were 1,500 tendentious edits in our own investigation across roughly 20 different wikipedia entries, and we know that all of them pointed in certain ways towards chinese geopolitical interests as far as we can tell. what we do not know is who was behind these edits. we don't know why in fact they were done, but most importantly we can not make a direct link between any of those edits and the chinese government themselves. 0k. so you've put this to the wikimedia foundation which is the kind of overarching body that oversees wikipedia. what's their reaction? broadly they're saying that whatever

you're actually doing on the site if you're systematically doing it for political gain that really is against the very reason why wikipedia was really created. but the problem is that we've heard the same from facebook and other web 2.0 companies where they're basically saying, "well, it "violates our terms and conditions." but people still do it. the ace in the hole for wikipedia would be that they're now passing these links that we've sent them and all the evidence that we have to their tens of thousands of community editors and volunteers wikimedia, the foundation is not actually responsible for the content, that would be the volunteers themselves. which of course is a huge benefit for them. they can mobilise all these people around the world who will constantly patrol and protect the site. and in fact do return many of the edits that we saw at least back to their original state actually quite quickly. doesn't this come down to different definitions of the truth? of course it's worth remembering that, at least in the eyes of the authors of the papers we covered, they were simply

being motivated by desire to correct western misconceptions and biases regarding china. you know, you've got with wikipedia this kind of vision of the open internet, open knowledge, open source, but then in stark contrast you have this another kind of newer perhaps but rising idea and that is the kind of increasing power of states online. you know, the idea that geo political battles will now be fought online too, and that places like wikipedia may be becoming too important or too powerful for states to really ignore in their struggles over the truth and in defining what people believe. carl, how absolutely fascinating. thank you so much for the research. hello and welcome to the week in tech. it ruled that courts in the eu can order facebook to remove users comments to have been deemed illegal. the eu also brought

in new repair laws. white goods will have to be built to be longer lasting. makers will also have to replace replacement parts for up to... parts for up to 10 years. elon musk unleashed starship — the shuttle is expected to take its first test flight later this year. and gopro has allowed bloggers to bolt on and new... and gopro has allowed bloggers to bolt on a new mic... after mixed reviews for the hero seven. osteoarthritis patients are testing the world's first smart love thanks to a pilot run by hospitals in madrid. it can be programmed by doctors to heat up, vibrate and perform physical therapy whilst patients rest at home. the firm behind the glove says this makes it easier and cheaper for health services to treat patients. and finally a bright—eyed robot assistant is helping out nurses at a hospital in texas.

made by diligent robotics, it uses al to recognise its surroundings and features a camera and gripper to pick up objects. don't worry, the humanoid bot is only running errands at present, so there is no chance of a robot bloodbath just yet. so there is no chance of a robot ——bedbath just yet. we're here at microsoft's future decoded event, which is looking at al and how it may change workplaces across the world. back in the day, microsoft changed everything with windows making itself the most valuable company in the world. and bill gates the richest person in the world. but then things went a little wrong. mostly because microsoft missed the mobile revolution and fell well behind apple and google. but then, as we told

you earlier this year, along came new boss satya nadella with a master plan to return microsoft to its former glory. well, now dave lee has caught up with the man himself to find out how that reinvention is going. this week, microsoft chief executive, satya nadella, was in new york to show off a range of new devices the firm has been working on. but before showing them to the world, microsoft invited me to seattle and into their lab, a place where the firm's devices are conceived and perfected in a number of curious and, as you'll see, painful ways. engineers here are able to prototype and make design modifications on the fly. going through many different iterations before settling on the final design that will get mass produced in china. but that doesn't happen until it's gone through a series of extensive and unusual tests. this is microsoft's human factors lab, it's here where they test their new devices for how they're going to look, how they're going to feel —

including under different lighting conditions like when you're at home or if you're in bright sunlight. the work that takes place in the human factors lab is a closely guarded secret. in fact, it's a closely guarded secret even once the products they've made are released to the public. as far as these people are concerned, if they've done theirjob properly, you won't notice their efforts. this machine is monitoring my brainwaves to see how much concentration it takes to perform certain tasks, such as typing. and this test is looking at how much muscle strain i endure when i open a laptop. something that didn't seem too strenuous to me but is apparently very important. to find out what i'm going through, a wire the width of a human hair is implanted into my hand and then monitored for activity. and then we have our ears to think about. microsoft is following apple and amazon and samsung in coming out with its own so—called smart earbuds.

these are devices that you stick in your ear to hear things, obviously, but also you can use touch gestures to interact with your computer. what we have is a small amount of prototypes that it took to design surface earbuds. and it was a long journey — it was roughly three years. we scanned thousands of ears and we took data from that. we also took the approach ofjust trying it on. i mean, we can take a tonne of data from the ear scans and inform us of general shape, but it really comes down to making the prototype and putting it in people's ears, so hundreds and hundreds of people will come through this lab. try it on, give us feedback, and then we go through another iteration. microsoft's big secret at the new york event were these two folding devices the surface neo, the surface duo. the neo is essentially two tablets hinged together running a modified version of windows designed to work

either across two screens or on two screens independently. and the duo is essentially two smartphones together running google android instead of windows. the overload is much less. i'm staying in context on a web browser on one side i'm using edge on one side and i'm looking at my neo on the other. i have a calendar on one side i have my mail on the other but it's structured in a way that you're actually optimizing and feeling good about being productive. the devices have been a long—term passion project of a microsoft chief product officer. he's very attached to this idea. the devices won't come out until late next year. before then, a few glitches need to be ironed out. i'll open mail here. it's a pen. it just touches a little bit better with a pen. oh, yeah. microsoft has taken a different approach to their rivals. samsung's galaxy fold, for example,

is already on the market, and that has a screen that goes all the way across the hinge. although some users have complained that that screen isn't particularly reliable. this is the biggest range of hardware microsoft has ever launched in a single year. adding new lines to the side of its business that, in less than a decade, has become worth more than $5 billion a year to microsoft. we were the first to create the two in one category where no one thought that that could be done. we then created even the desktop that could become a canvas for creativity with studio, we created holo lens that brought what was digital and physical together. and we've continued to innovate, and so therefore this two—screen innovation is what we think is fantastic for the kinds of things that we care a lot about — which is productivity, creativity, pen input. to be able to have teams on one side and then to be able to take notes, like,

that's an everyday scenario. but samsung bendy screen, they've pulled it off with a few reliability issues, they seem to have done the same thing — huawei. so was microsoft trying to do that? or did itjust take a different route to a different direction? in fact, i've been using even the samsung, it's a beautiful device. we've worked very closely with them on getting our software on samsung and so we think that that's great innovation too. so i celebrate whenever new computers and new computing is created, because i think that's what the world needs if anything. one of the other things we want to sort of do is that consumption is great, right? i mean more browsing, more shopping, more binge watching, all as you and i do. but also more creativity and more productivity is also great. we want that balance to some degree. the last ten years has been more about consumption, less about creation, and we want to swing that balance to the right place. that was dave lee. you know we love keeping tabs on the latest movie—making techniques, especially cgi and animation. so kate russell has gained extremely rare access to dreamworks studios in los

angeles. to look at the secrets of animated film making with a look at their latest release — abominable. of course! really? no. shrek, kung fu panda, how to train your dragon, just a few of the film series created by dreamworks animation studios. hey! what are you doing out here? and their newest film, abominable, has released in the states and topped the weekend box office. as animation techniques improve, the amount of time it takes to make these movies increases exponentially. take this guy for example. the original shrek in 2001 took six terabytes of data and around five million hours of render time. for abominable, we had 150 terabytes of used space that'll be archived, and then we had another 150 terabytes of temp space just for effect simulations and all that data.

and we used about 181 million render hours. work on abominable began seven years ago. so why does it take so long to get the original idea from paper to screen? making an animated movie is almost like you're making a live action movie. and all the technicalities of a camera in live action are now incorporated into animation. before we used to do all in 2d, we used to film with a camera locked up and on top of a table, so everything had to move down on the paper. but with this kind of technology, the camera's inside the drawing and we move the camera around the drawing, in that we find the character, and we have to build the whole world that way. back in the shrek days, you would basically try and light and render a scene, and you would wait and wait and wait to see an image, and then you can make your changes and you wait and wait again. and so the feedback loop, which is critical for the artists, has really improved.

so this is a moonray interactive render, and as you can see, i can interactively move the character around and space change the camera but i can also go through and actually start making lighting changes, and as i do that, the feedback is almost instantaneous. but the overall time has increased. so that's why the overall render hours has increased, because we're just doing much more complex lighting calculations. so how animated films are made here has changed massively over the last couple of decades, with more data meaning more detail. the shot is around 120 frames or 220 frames, and that's about 14 feet of animation. so that means this shot should take an animator two weeks to do. technology might be at the heart of realising an artist's vision, but very often the soul of an idea comes directly from the natural world. take these koi carp in the lagoon here at the dreamworks campus.

they were an inspiration for the amazing cloud koi flight scene in the movie. here's our final image which touches on the lighting for the sequence. they really did an amazing job. and the results were far from abominable. guys, what are you doing up here? get away from her. i'm calling the police. he's not dangerous. look at him. he's a yeti. brilliant! that was kate in la. and that's it for this week. but don't forget, as always, you can find us throughout the week on facebook, instagram, youtube, and twitter at bbc click. you'll also find us on wikipedia. look it up. thanks for watching.

hello there. it has been a soggy start to our sunday across northern and eastern parts of the uk. as we head onto the afternoon the heaviest of the rain is confined to eastern england and east anglia, lincolnshire and east anglia with heavy rain and the risk of some minor flooding heavy rain and the risk of some minorflooding and heavy rain and the risk of some minor flooding and atrocious conditions on the roads. this is the culprit. this is fronts here which has almost been stationary across the north and east of the country becoming more confined to the south—east as i mentioned. for scotland, a slow improvement through the afternoon with a little bit dry weather developing. a few showers across the west and across the east where it remains blustery in the northern isles. heavy rain in lincolnshire and down into east anglia which could cause further issues. for much of northern

ireland, wales and the south—west of england some good spells of sunshine but a few showers in the midlands. it starts to turn windy as well as this develops in the south—east for southern inland and wales. but in the sunshine we should see highs of 17 in the south—west. generally the low to mid teens further north. feeling cooler where you have that strong wind on the east coast. dry for a while tonight on the ridge of high pressure but then it frontal system pushes in in western areas and the rain will be quite heavy and also strong winds and severe gales across the north—west of scotland. tied in with this area of low pressure you can see tightly packed isobars which is the reason for the gales and severe gales. that weather front slowly pushes its way eastward. it will weaken and fragment as it reaches much england and wales but will still bring a rather cloudy and damp day, quite breezy as well. the heaviest rain further north. the scuds brighten up

into the afternoon but it stays very windy with gusts of a0 to 50 miles an hour but further south in a blustery day as well. temperature was a few degrees down what you have had over the weekend, 12 to around 15. an unsettled day on monday and it looks like it will remain u nsettled it looks like it will remain unsettled for the rest of this week, often windy as well. winds coming in from the atlantic soak temperatures around the seasonal average. spells of rain followed by sunshine and showers. some sunshine, it's not all doom and gloom.

good afternoon. tens of thousands of demonstrators have again taken to the streets in hong kong, defying a ban on wearing face masks, which has been imposed under a new emergency law. police used tear gas and charged with batons to try to break up the crowds. the protests began injune over plans to allow peoit‘s the latest in months of street protests, wdemanding greater democratic freedoms our china corrspondent robin brant reports. standing and
