excited? just a little. the start of a new season left some liverpool fans literally jumping forjoy- and who can blame them? they are the european champions, after all, but becoming english champions is what they crave. after being pipped to the title last season, they began this one against newly promoted norwich. a big night for the visitors, but their premier league dream soon became a nightmare. an own goalfrom their captain, grant hambly, set the tone, as any early liverpool nerves quickly vanished. mo salah scoring a typically ruthless second, before norwich's defensive frailties were once again exposed by virgil van dijk. it was liverpool at their irresistible best, and by the time divock origi landed a fourth just after the break, even the most culinary norwich fan surely found it hard to stomach. to their credit they didn't crumble.

as the home side faded, the visitors flourished, finnish striker teemu pukki giving norwich some second—half consolation. still a comfortable 4—1 victory for the hosts, their latest title challenge off to a winning start. yes, liverpool's season is up and running. remember, they're looking for their first league title since 1990 — could this finally be their year? a tough season ahead though. the champions, manchester city, get their campaign under way later against west ham. no sergio aguero or marco silva in the starting line—up for manchester city as they begin their campaign away at west ham. there are four 3pm kick—offs, one of those crystal palace against everton,

before tottenham take on aston villa in the late kick—off. four games in scotland today. motherwell are taking on champions celtic at fir park. it's currently 1—1. later on, stjohnstone take on livingston, hamilton face kilmarnock and hearts welcome ross county. naomi osaka has returned to world number one, despite a straight sets defeat to serena williams in the quarter—finals of the rogers cup. williams beat osaka 6—3 6—4. it was the first time the pair had met since last year's us open final when williams argued with the umpire before osaka went on to win her first grand slam title. ash barty now drops off the top spot, following a run of tough results. wales, england and ireland all play world cup warm up matches this weekend as the build—up begins ahead of the rugby world cup. ireland take on six nations strugglers italy in dublin first up, before england face wales at twickenham tomorrow, it's an experimental irish side with 12 players to be cut from their squad before the tournament in japan

which starts next month. that's all the sport for now. this week, shutting down the net. speeding up border checks. and completing the circle of life. oh, everyone, calm down. we're here. the back—up has arrived! stand by, please. stand by, alexandra palace. switch out, regions, switch out. and cut to the palace. this is alexandra palace,

the birthplace of television. on 2 november 1936, the world's first regular high—definition public television service was broadcast from there. tvjoined radio and the printed word in bringing us entertainment and information, to bring us together and broaden our minds. but these days, information has another way of getting out. social media has given us all the power to say whatever we want and show whatever we want, and that has caused several governments big problems. some countries like china, iran and saudi arabia block news and discussions about topics they don't want their people to hear about. but many more countries will sporadically block social media sites, slow down internet speeds or even switch off net access altogether to try and stifle unrest and dissent at sensitive times.

and the country that shuts down net access the most is? india. and by far, the bulk of those shutdowns are in the disputed himalayan region of kashmir. this week, the indian government removed the special status of the part of the region that it administers. it was an unprecedented move that's seen schools closed, demos banned, leaders arrested and, of course, the internet shut down. a couple of weeks ago, david reid went to kashmir to find out more about the regular shutdowns that were happening there. as it turned out, he was one of the last foreign journalists to be allowed in. kashmir might look peaceful — it isn't. authorities here are fighting a long—running insurgency. many kashmiris and others say india is an occupier.

almost 50,000 have died in decades of violence. even before this week's clampdown, authorities regularly shut down the mobile internet, as i found during a recent visit. our business is an online food delivery service, it's the first online delivery service start—up in kashmir. more than ll0 times this year, kashmir‘s mobile internet has been cut off or throttled back, not great for sales of chicken wraps or spicy mutton curry. what do you do when the internet is off? every time we have to call our customers, our data base customers and we try to send an smss that we are serviceable. last time, we had pamphlets and we distributed them to colleges and schools. it's going back to the 19505 and working without internet and internet is a very important part of your life right now. normally it's only the mobile internet cut off, not domestic broadband. why don't you just use broadband? it's just too expensive. broadband is more expensive than 46

and everyone can't afford a connection at home. the measure is unpopular and there are suspicions it's less about security than just stifling dissent. they are claiming we are the largest democracy in the world, but it's not a democracy because you can't suppress the voice of dissent in a democratic system. i headed over to speak to kashmir‘s police. interestingly, their internet policy seems less about foiling militant operations, but more about preventing propaganda and rumour. we are here fighting a proxy war. we see a lot of content from our neighbourhood coming here and trying to create a propaganda which is absolutely not correct and at times, that leads to a serious law and order problem. kashmiris joke that the internet is just a switch on some bureaucrat‘s desk and there is a feeling that it's all a bit too easy. there is no transparency. some shutdowns in

india are frivolous. according to this tracker run by a delhi—based ngo, the mobile internet was cut off 30 times in rajasthan last year. no insurgency there. and at least four of those were to prevent cheating in police recruitment exams. authorities say shutdowns are signed off by magistrates and audited. we have to take their word for it. the audits are secret. our tracker is built around exposing reality of the internet shutdowns, the quantum of internet shutdowns in india. what we demand of the government is transparency. there is no government published data on shutdowns. but we also have to rely on citizens reportage. india is probably one of the strongest democracies to utilise this policy, which is problematic.

india cuts off the internet more than any other country. ok, the population here is enormous and much of the time, india's internet has been pretty open. select censorship, but without a china—style content firewall. that said, critics contend that countries are taking india's lead, cutting off comms in a crisis. by the way, they also say shutdowns actually increase violence. what you are doing, if anything, in curtailing access to the internet is disallowing people the ability to organise, again, peaceful demonstrations which are well within the confines of the law. it creates a disrupted communication environment which potentially induces more chaos, more violence. this week's clampdown has meant a complete communications blackout — internet, phone, tv. the un's special rapporteur has called it draconian and kashmir has been gagged, cut off from the rest of the world. that was david reid in kashmir.

of course, there are many parts of the world including here in the uk where governments don'tjust shut down the media or the internet to try and control public conversation. but that also has consequences. it was an attack streamed live on the internet by someone apparently determined to use social media to spread a message of hate. if you can't control what's being uploaded, stop the uploads. during the christchurch massacre, thousands upon thousands of videos were being uploaded to facebook and uploaded to youtube and you could see tens of thousands of views. people all across the world, watching this content. we will look at the role social media played and what steps we can take. they are the publisher, not just the postman. we know that that content will have radicalised people and they were sort of saying, "0h, it's a problem with our ai,

"our ai is not recognising this content, " but they should have just shut it off. carol cadwallader is the journalist report facebook and cambridge analytica story to the mainstream and she is the main voice in the new netflix documentary which tells the story of how users' data was gathered and analysed to try to influence elections. she has campaigned to get facebook to work harder to stop the spread of violent content, hate speech and fake news across its network. everything that has sort of enabled us to develop as a country and become the society that we have is directly under threat now. instead of shutting websites down, authorities in the west go for the financial jugular. the settlement imposes a record—breaking $5 billion penalty. this fine was for deceiving users about how it used their data. but if the threat of fines doesn't

pull facebook and other social media platforms into line, might we start to see even more countries block access completely? carol cadwallader thinks it's still possible to avoid both fines and censorship. one of the really amazing statistics about facebook that i heard is that one in seven people that facebook employs to do content moderation works on german content, and that's because germany has very strong laws around hate speech and if you don't get it down, you are going to be fined. i think my colleague at the guardian, alex hood, worked out what it would cost to have the same levels of german content moderation across the world and it would cost facebook something like 0.5% in profit. hello, and welcome to the week in tech. it was the week in which british airways passengers were left stranded after 300 were delayed

or cancelled because of it problems. ouch. 500,000 bank customers were asked to change their pin for their monzo bankcards after it problems. ouch. and japan's newest flying car took off the first time without anyone in it and sort of bumped back to earth again with everyone standing well back there. bit of work to do. there was light at the end of the car tunnel, though. hyundai unveiled its plan to make a solar car that is up to 60% powered by the sun. it follows recent announcements from toyota that it will provide solar panels for its hybrid prius and a new manufacturer, lightyear. britain's nhs is to set up an artificial intelligence unit to help work out patterns in clinical trials, existing treatments and patient flows. this is the russian military‘s new stealth drone. the okhotnik, which means "hunter", took a 20—minute flight but found nothing.

samsung has revealed its biggest smartphone to date. the galaxy note 10 plus comes with a new gesture—controlled guest pen. it supports 5g and has a depth—sensing camera on the back that might help you measure the hole in your pocket if you buy one. and finally, let's all wear a tail. researchers in japan say their ll—motored motored creation helps with balance, climbing, carrying stuff and looking like a monster. it's the future. get over it. the history and the politics surrounding israel are, of course, highly contentious but its situation in the world has made it a focal point for new security tech start—ups. stephen beckett has met a company whose technology looks set to rapidly change the way that borders and checkpoints are policed

around the world. physical borders and checkpoints have been around for almost as long as civilisation itself but one thing that goes hand—in—hand with intensive checks is queueing, potentially long waits while each vehicle is manually inspected for contra band or even security threats. i'm here in tel aviv to see how one company is using artificial intelligence to rethink the way those checks are done. this is uveye, the first of its kind advanced threat recognition system that scans the underside of your vehicles. dramatic video aside, the uveye system has been using borders and checkpoints around the world. it's key selling point — the promise of detecting unexpected items under moving vehicles faster than any human possibly could. the question is, how could they do that without compromising on safety? this is sort of where you might do in a normal inspection. down on the ground with a mirror

that lets you see under the car. from here i can see the edges quite well but the middle is a bit of a mystery to me. of course, professional security would have more knowledge and hopefully a better torch but without raising the car up, they would still struggle to see in as much detail as the system can. hidden under the ground are five high—res cameras that activate when the vehicle is detected. in about a second, they take thousands of photos that are then combined to create a high—res model of the underside of the vehicle. as you can see, a very high resolution. you can read the writing. you can read that this volkswagen was made in poland. doing checks by eye like this could still take a human a long time. that's why the real idea is to have deep learning algorithms do it for you, automatically analysing the images for anything that shouldn't not be there. this is a typical 300g of size, ok?

and this is1 kilo. and now it's scanning for threats. you can see the automatic detection, we found the three boxes. i mean, these ones, ithink i would have spotted those ones but this one down here... this one was very hard. we didn't spot it before the system did. just like our own fingerprints, tiny details in the images like the part numbers or even small scratches can be used to create a unique identifier for each vehicle. that means that even if you were to, say, change your numberplate, the system can still recognise your car if it's seen it before. ai—powered systems like these are only as good as the data they're trained on. here to create the data, uveye had to hire hundreds of rental cars from around their office and scanning those cars taught the system what a normal undercarriage is supposed to look like and knowing what normal looks like means the system can do

more than just spot contraband. at our next stop they are using the system to help keep tel aviv‘s buses on the road. when a bus leaves the depot, they drive over a uveye detector, just like with the cars, the huge image that comes out can be scanned for unexpected items, but they can also spot if there is a maintenance issue like an oil leak or other damage. the latest version of the system uses even more cameras to create a 360—degree view of an entire vehicle. so notjust the undercarriage, but the sides as well. that means things like scratches, dents and tyre damage could also be picked up. earlier this year car companies volvo and toyota revealed they were investing in the tech, so in the future we could see it being used when you buy, sell or even rent a car. you can imagine that might save, 01’ even cause a few arguments with hire companies.

in the meantime, though, security is still the main focus of the system. the question is, do we feel comfortable handing over this kind of responsibility to an ai? classical music plays. here at the barbican's life rewired season, a rehearsal is taking place. but it's no ordinary rendition. an array of cameras is tracking the musicians' every move. now from there, artificial intelligence is analysing what's being seen, so it could be deciding on what gender, what ethnicity or what age it thinks someone is, but it is also keeping track of their emotions. this experience is meant to illustrate the difference between what a machine sees and what a human can see.

and right now there is clearly quite a big difference. sight machine uses a mix of old computer algorithms and cutting—edge ai, much like that used by self—driving vehicles orfor reading biometric data. it then recreates its findings in a picture or as text. yet... first of all, it thinks david is between four and six years old, then it says david could be up to 100 years old. there is definitely something not quite accurate here. i have to say, every time i have looked up at the screen, and ai has been tracking my emotions, it doesn't have anything to do with what, at least what i think i know about myself, or what is happening right at that moment. to ai, emotion comes down to certain premises. one, there is such thing as emotions, right?

which seems self—evident. if you look throughout history, different cultures at different times have used very different languages and very different taxonomies to describe what we talk about as emotions, right? also, typically in computer vision systems, there are six emotions — fear, happiness, sadness, disgust, anger, and that is pretty questionable as well. i think if we imagine our emotional lives, they are far more complicated than that. trevor has worked with this tech a lot, and he says he wasn't anticipating greater accuracy. he's not trying to rubbish all the good that al can do, though — merely to highlight what he views as the pitfalls. i think we want to have a lot of faith in technologies that are going to be smarter than us, that are going to be more objective and fair than us, and i think what the performance shows is that we're very far away from that. of course this system doesn't represent the ability of all ais, and not everything it

suggests is wrong. but many of the decisions it makes are based on limited opinions orfactors, and of course the machines will keep learning. this isjust a reminder that when it comes to emotion, 01’ some more nuanced concepts, ai is not a patch on us yet. classical music continues. brilliant, that was lara and her quartet. i am on a different stage right now, this one belongs to the alexandra palace theatre, recently renovated after laying derelict for 80 years. and what an amazing space it is, don't you think? in the 1930s this was also a cinema, and that's where we're going next. to the latest box office blockbuster. the lion king opening theme plays. the idea of embracing something that

took what technology has to offer to create a photo real version of this story, as told through the eyes of what would feel like a documentary, a live action documentary crew, was an exciting prospect for us. disney refers to this as a live—action film, which is a bit misleading, but i think it is tonally correct, because we did use those techniques, and hopefully it does feel like something that was actually photographed, even though every shot — with the exception of one, actually, every shot in the film is completely computer—generated. and every performance is animated. we built it using tools to create essentially a completely digital 3d environment, and then you have 3d digital animals that are in that environment, and that's how you would do the final render of it, whether it was a marvel movie or whether it was a film like this. but since we already have those assets we could bring that into this consumer facing vr system, using in this case the unity game engine, and because we now have

this environment and vr, we can have people enter into the digital set and be able walk around and look at it as though we were on a scout, and it allowed me to hire someone like caleb deschanel, who is a great cinematographer, who i've known for a long time and wanted to work with, but had no background in visual effects — and we made it user—friendly, so he could walk around with us, with the production designer, the visual effects supervisor and the director, look at the set, say, ok, we should put the camera here, let's see the lion rehearse the scene, and the ad would hit the button and run the animation cycle, we would watch like you would in a regular set, you think about where he wants the light, we could move the sun if we had to, move some trees around, so we had a full live—action film crew in vr, operating camera equipment as though it were a live—action set. but we always tried to limit ourselves in what you could achieve in real life, and that is what gave it the aesthetic that people are reacting so well too. all right, let me see

what we are dealing with here. it's a lion! phase one is this whole virtual shoot, where we do rough animation, we build rough versions of the sets, they look like rough video games, and you put it together, and you shoot every shot, and now you have a complete edit of the whole movie with dialogue and temporary music, and you really have every shot. it is notjust a study, these are choices that jon and caleb and the other filmmakers were putting into place. every one of those shots is like a 3d file, a data file, that comes here to mpc london and we have a layout department that works out all the space and all, and imports all those cameras and lines it up and makes sure the scene is going to work. animation department jumps right on the characters and starts creating the super delicate, fine performances. the environments and sets department creates the entire african savannah, painstakingly making literally thousands of plants and trees and rocks. life's not fair.

is it, my little friend? and the lighting department and the simulation departments which add the movement of the water and the movement of the fur, they all come in and complete the realism, so the world, the character in the world, the way the light works off those materials, the way every blade of grass is moving, everything has to be just right. we're here! everyone, calm down, we are here. the backup has arrived! at its core, cinema comes from the tradition of illusion, and melies, and using all of these tools to make the audience believe they are seeing something that they are not. and that is part of the delight, i think, of something that is effects driven, especially if there is a wonderful story behind it to carry it. you must take your place... in the circle of life. lion roars. that was fascinating, wasn't it. if you liked that, then you might like to watch the full 20 minute chat with jon favreau,

which is on our youtube channel. there he goes into everything from iron man and star wars to digital doubles and deepfakes. well worth a look, youtube.com/bbcclick is the address. don't forget we also live on facebook, instagram and twitter, at @bbcclick. thanks for watching and we will see you soon. hello. if you are on the move this weekend or have any outdoor plans, the weather could still cause a hindrance. we've got a risk of flash flooding and some further downpours at times, but we could also see gales cause issues across england and wales through the rest of today. we could see winds quite widely gust 40, 50, maybe 60 mph,

more especially around the coasts, but even inland that's strong enough to bring a few branches down and bring further travel disruption. showers in the south ease a little bit. further heavy rain in parts of northern england, northern ireland, and some thunderstorms in scotland, too. tonight, they will ease a little bit, but further downpours can be expected, and temperatures tonight between 10 and 15. as we go into tomorrow, the winds in southern areas will ease a little bit. the best chance of some sunshine here, but a few thunderstorms developing later. we'll see the breeze pick up across scotland and northern ireland, making it feel that bit cooler, but we will see brighter weather develop to the north and west later. in parts of central and southern scotland, towards the far north and north—east of england, we could see some of the wettest spots, with again that risk of flooding.

good afternoon. national grid has said it will "learn the lessons" after nearly a million people across england and wales lost power yesterday. it confirmed to the bbc that although two power stations had failed simultaneously, it's not thought to have been the result of a cyber attack. the regulator ofgem has demanded an urgent report into what went wrong. thousands of train passengers were stranded, ipswich hospital lost

power and homes throughout the country were
