creating something to draw the gravitational pull of consumers. jon, thank you so much. now it's time for a look at the weather with ben rich. just about all of us are going to get wet weather tonight and into tomorrow. rain spreading east and some of it will be quite heavy. there may be some travel problems, may be flooding. you see the wet weather moving quite slowly east overnight. you can see the dark blue and green, very heavy downpours and may be some lightning. quite windy, especially over the north of scotla nd especially over the north of scotland but mild, 9—12. tomorrow, the rain stalling over eastern parts. eastern england into south—eastern scotland will see persistent rain. into the afternoon, the rain may move away from the south—east and it may fizzle elsewhere. further west, south—east and it may fizzle elsewhere. furtherwest, blue skies and sunshine, the odd shower. next

week, very unsettled, showers and longer spells of rain, and brisk wind. hello this is bbc news. the headlines. democrats leading the impeachment inquiry into president trump issue a legal order demanding that the white house hand over more documents. the un's human rights chief questions a decision by hong kong's government to ban the face masks frequently worn by pro—democracy demonstrators. the government indicates it could clarify its new brexit offer after the eu called for ‘fundamental changes‘. the wife of an american diplomat leaves the uk after becoming a suspect in an investigation into a crash which killed 19—year—old harry dunn in northamptonshire.

now on the bbc, it's time for click. this week, microsoft boss satya nadella uncovering state—led internet manipulation. and abominable animation. 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 weaponized. states have and are weaponizing 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, wikipedia's attack. 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? the repeating editing articles on the english and chinese wikipedia and they wipe out the taiwan open and just keep the china. saying taiwan is part of china, part 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 to amidst a general rising atmosphere of intimidation. taiwanese wikipedians or people that voice anti chinese opinions on wikipedia, they get attacked and trolled and abused and doxxed on wikipedia regularly attacked. what does wikimedia global think of all of this? is it because they're american and they just don't know. the hostile word. well it's not. and lost in translations.

heather ford has researched political edits on wikipedia. whenever you have a group are. 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 1600 times where across 20 topics or so wikipedia was changed to broadly bring its content closer to the chinese government's line. volunteer efforts of wikipedia. our own investigation has managed to find nearly 1600 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 in fact rioters. academic shirley yu thinks that trying to tell your story is really the natural behavior 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 primarily over the past four decades has really framed the china story

and the interpretation of based on a western philosophical and political economic framework and i think today china does owe the world a china story told by itself in from a china's perspective, i think it's not only chinese privilege. it's 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 people from the diaspora you know patriotic chinese are editing these you know wikipedia entries but to say that is also to ignore that larger structural coordinated strategy of the government has to manipulate these platforms. heather ford isn't surprised at all to see that 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 prioritized 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 1500 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. whatwe do not know is who was behind these edits. we don't know why they were done. 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 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 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 mobilize 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'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, the idea that geopolitical 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.

for the hero seven. osteoarthritis patients are testing the world's first smart glove for at home treatment thanks to a pilot run by pilots in the 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, moxie uses al to recognise its surroundings and features a camera, sensors 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 bedbath just yet. we're here at microsoft's future decoded event which is looking at ii 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, 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 take 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 and 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. the duo is essentially two smartphones together running google android instead of windows. the overload is much less. i'm saying in context on a web browser on one side, i'm using edge on one side and i'm looking at my mail on the other. 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. the curse of the demo. 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. 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 that's an everyday scenario. but samsung bendy screen they've pulled it off with a few reliability issues, huawei seem to have done the same thing. so was microsoft trying to do that? or did itjust take a different route to a different direction? different direction. in fact, i've been using even the samsung fold, it's a beautiful device. we've worked with 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, it all as you and i do that 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. now here on click, 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 camera in live action are now incorporated into animation. before we used to do it all in 2d, we used to film with a camera locked up and on top of a table so everything had to move moving 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 an interactive render and as you can see i can interactively move character around in 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 the inspiration for the amazing cloud koi flight scene in the movie. here's our final image which touches on the lighting for the sequence. 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. 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. no shortage of rain in the forecast for the next 2a hours. many parts of the uk, today wasn't a bad day. quite a lot of cloud but a favoured few saw some sunshine. further west the cloud was thickening. we saw some outbreaks of rain. you can see on the satellite picture, the big swirl of cloud, the low pressure to the north—west. this cloud is a frontal system pushing east,

moving slowly and bringing heavy and persistent rain. tonight if you're travelling overnight, a lot of rain which will be big puddles, surface water and spray on the road, pretty poor conditions. drying up a bit in the west late in the night. windy, especially over the northern half of scotland but it will be mild with lows of 9—12. tomorrow morning, this rain over eastern parts of the uk and it will be very slow—moving. central and south—eastern scotland, right the way down the eastern side of england, heavy rain falling. maybe some thunder and lightning. 40, 50 millimetres of rain in places. the met office yellow warnings in force, the lowest tier of warning. it has been so wet lately, another dollop of rain may give some localised flooding problems. this rain is likely to pivot through the day.

a chance the southeast may brighten up and parts of east anglia as well. further north, the rain may fizzle and break apart. to the west, a different day, blue skies and sunshine to be had, temperatures 12—17. the late state sunshine in the west comes courtesy of this area of high pressure but it doesn't last long. by monday, the low pressure is back. quite a deep, lumbering low that's going to bring the frontal system eastwards through monday to start the working week. this rain fizzling as it moves to the east of the country but behind it in northern ireland and scotland, the rain clears and we have a mix of sunny spells and thundery showers. temperatures about where they have been. 12-16. a windy day, especially in the far north—west. we keep the strong wind into the middle of the week. a mixture of sunny spells and showers. that's the theme through the week, showers or longer spells of rain, and it will often be windy.
