for click. this week, hate for sale. the ultraviolet cleaning squad. and halo, will you be joining team xbox? hey, welcome to click. now, as more and more places start to open up here in the uk there are some people who are starting to think about whether travelling or going abroad for a summer holiday is a possibility. and is safe. and that's why today, lara is not at home, she is at an airport.

yes, that's right. i'm not going any further than heathrow airport, though. i have to say it is amazingly quiet, here. wow, so what are you up to, then? we've been given some behind—the—scenes access to take a look at some of the technology that is being used to help keep the airport covid safe. 0k, we'll have more on that later in the programme, so see you in a bit. first we are going to return to something we often talk about on this programme, the battle that social media companies are fighting against extremist content and hate speech. normally companies like facebook, twitter, and more recently tiktok are the ones making the headlines, but there are other outlets for extreme views, too. for example, it is totally possible to buy racist and far right products from some of the world's biggest online retailers. james clayton has been investigating. it's a sad reality that racism is alive and well online, but it might surprise you that

some of the biggest companies in the world are selling racist material and products online. our investigation has also found that online retailers own algorithms often promote racist products which they are then benefiting from financially. to the degree that algorithms can learn, they can also be taught to be more responsible, otherwise these companies essentially just throw their hands in the air and say yes, we are going to make it easier for you to be an extremist. the black lives matter movement has been an awakening for many, notjust people but companies too. after george floyd's death, chief executive after chief executive stood up and declared themselves and their organisations behind the movement, including amazon's jeff bezos and google‘s sundar pichai.

but have these companies been practising what they preach? i wanted to find out, so i decided to do some online shopping. first up, the undisputed heavyweight of online retail, amazon. you may be surprised to see that white power flags are being sold on the platform. they're not called white supremacist flags, but, if you reverse google search it, you will see that they definitely are. now, i am a tech reporter, i'm not an expert in neo—nazi flags. but, when i clicked on that flag, something caught my eye. in the "frequently bought together" box, amazon was suggesting another flag with a symbol i'd never seen before. i so i decided to look it up, and, yeah, it's another neo—nazi flag. amazon was suggesting to me, content, neo—nazi content, that i didn't even know existed. and if i click on that nazi

flag, i get more nazi stuff suggested too. some of the comments on these flags are pretty critical. "disgusted", writes one shopper. this is a neo—nazi flag, says another. but others are very happy. this person says that the flag would be great for use in parades, and thanks amazon for making it happen. so, next time you see a far right march, and you see flags on display, it is possible that they were bought on amazon. amazon may have profited from them. the weirdest part about this is how easy it is to land on white supremacist material, without me ever having typed in anything to do with white supremacy. we need to demand that the companies that are providing these algorithms don'tjust sort of say it's the algorithm's fault, it's not our fault, they need to constantly be on top of, what is their algorithm recommending, and making sure that they are fine tuning it so that people cannot game the system or, worse yet, that somebody who is just

on the periphery of some extremist movement doesn't get deeper into that movement and its subculture because the algorithm took them there. these symbols matter. they are the emblems of the extremist, racist far right. the christchurch shooter, for example, wore these two symbols. there's lots more i could show you on amazon, but let's take another example, this time, the kkk, the ku klux klan, from another online retailer, wish. now, wish doesn't have any explicit kkk merchandise but it does have this old 1960s cartoon. however, if i click on "related items" suddenly i'm offered a load of things that are associated with the kkk. in fact, the first two items suggested are a hood and a white power sticker. there also suggestions for neo—nazi flags, white power rings, etc, etc.

the algorithm thinks that i'm interested in white supremacy and so that's what it's offering me, and there's more. the far right extremist movement, the boogaloo boys, is banned on facebook. members of the movement have been charged with terrorism offences. one man has been accused of killing state officials. type "boogaloo" into wish, however, and you get a load of military equipment. the military equipment itself isn't labelled as boogaloo, but the algorithm thinks that's what you might be interested in. it wasn't just this. all three online retailers we looked at, amazon, google and wish, all had boogaloo content for sale. despite them being banned on other platforms. all three have now taken down those products. on google, too, we found racist literature for sale. now, we thought about this and decided not to show it to you.

here's what the companies told us. first off, amazon removed everything that we showed them. they said... "the products in question are no longer available and we have taken action on the bad actors that offered the products and violated our policies." google, too, removed everything we showed them, saying... "we don't allow ads or products that are sold on our platforms that display shocking content or promote hatred, intolerance, discrimination or violence." and wish told us... "we are working hard to remove these items and taking additional steps to prevent such items appearing again. it's notjust these companies we could have focused on. many other online retailers also have problematic products for sale. the big question now is, what should and shouldn't stay up, and how can companies moderate their platforms so that they don't profit from hate?

wow, well, that was james clayton, who is with me now online. james, i got the feeling that these items were only taken down when you notified these platforms. do you think they really are actively hunting for offensive items? that's the million—dollar question. in a way, there is no way of knowing, because they wouldn't actively advertise every time they took something down. when you do approach these companies and say, look, this is the kind of thing that you are either selling or you have on your platform, they say, oh, we didn't realise, we will take it down straightaway. but there's clearly an issue there, around how they moderate the platform. no matter how many human moderators you throw at a platform, it'sjust numerically impossible to take down the amount of content that they would need to. there is one crucial difference with this. than facebook and twitter. because facebook have, as they always say, billions and billions of posts they have to deal with, whereas when you are actually an online retailer, the amount

of products that you are actually selling is way fewer. so, that defence doesn't quite work when it comes to online retail. i guess this is just another example of the algorithm doing theirjob, and doing them well. the company is actively promoting other racist stuff. the algorithm knows that lots of people who type in "boogaloo", are interested in military stuff, and so it promotes and suggests military equipment. others might say it's not a particularly smart move to suggest military equipment to an organisation that has links to the extreme right and to terrorist offences. some of the items and symbols are not just racist, they have been appropriated. right, the swastika was and still is a hindu sign, and a lot of these new neo—nazi signs are old pagan signs. this is why the algorithm's so important, because if you are typing in "kkk" or "white

supremacy", it's pretty clear what you're searching for. are they platforms? are they publishers? how much responsibility do they want to take? you could argue that amazon could say look, we are libertarians, we think that we should sell everything. we don't make judgment calls on that. but, when amazon comes out and supports black lives matter, at that point, they do have a value system, and i think the big question here is, is supporting black lives matter and having this kind of product for sale, are they compatible? james, fascinating stuff. thanks for doing that report for us. hello and welcome to the week in tech. it was the week twitter announced plans to ban and suspend accounts linked to the conspiracy theory qanon whose supporters believe there are people plotting against the president of the usa. campaigners suggested that the test and trace programme in the uk breaks gdpr data rules as it was launched without carrying out an assessment of its effect on privacy.

the uk government said there was no evidence of data being used unlawfully. spotify has launched podcasts with video. it is only with a selection with of new podcasts for now. apple has announced plans for the tech giant and its entire supply chain to become carbon neutral from 2030. those of you with a craving for fancy futuristic food with a smaller carbon impact than the original, the bacon and pork belly in this sandwich isn't from a living pig. the meat was grown in a lab. the creators, higher state say that it is the first to produce a lab grown pork from 50% cultivated cells. and what do you get if you cross a machine learning and thermal cameras? that's right, a virtual hand. researchers at cornell university have designed a wrist—mounted device that continuously tracks the entire

human hand in 3d, as well as vr and human computer interfacing, it could be used in sign language translation. google‘s pixel buds have finally come to the uk this week, nine months after they were first announced. so, so i've been seeing how they stack up next to some other big brand wireless earphones. of course, the apple airpods pro and the snappily titled sony wfiooo xm3s. i am wearing the pixel buds now, and google has designed them to lie flat within your ears, so they have a low profile, which i appreciate, because you don't catch them if you are taking off your shirt or if you are wearing a hat. all three of these come with a case that recharges your earbuds. google‘s is designed to look like a stone, which is very nice, and it fits in that tiny extra pocket in yourjeans. sony's case is the outlier, because it's comparatively huge. i'm not a big fan of this rose gold effect lid, because the paint has started

to chip off. the big question of course is, how do they sound? i was never the sort of person to spend about £200 on a pair of headphones. until about two years ago my boss convinced me to buy these, because the audio quality and the noise cancellation were outstanding. and i never regretted it, because i wore them every day on the way to work, on flights, things like that. and the sony in—ear buds come fairly close to that sound quality. when i got the airpods pro, i was disappointed, because they cost more than any of these other headphones. but they just didn't sound as good. everything sounded a little bit duller. the pixel buds probably ran somewhere in between in terms of audio richness, but there is a problem with these. whatever i'm listening to, whether it's spoken word or music, there is a low level quiet hissing noise the entire time, almost like you are listening to songs on a cassette tape rather than a clean digital copy. and it's most noticeable if you are listening to music in bed at low volume. not everyone can hear it. my housemate couldn't hear the hissing noise but i could, and so could lots of other people complaining on the google message boards. for a sound product,

that's a fundamental problem. another weird thing about the pixel buds is that they don't have noise cancellation, and the sony and airpods pro both have really good noise cancelling for something so small. the pixel buds are at the end of the price scale where you would expect to have it. here is a quick look at some of the other features. the sonys come out top for battery life, and i've never had a problem with any of these running out, because they all recharge when you put them back in the case, the pixel buds and airpods pro have the added bonus of a wireless charging case, and both of them are also sweat resistant, while the sonys are not, although i used to wear them at the gym all the time, and they haven't broken yet. one little thing i'm really glad that the pixel buds get right is that they play a low battery noise at the same volume as the music you've been listening to, which is really important if you are trying to fall asleep. for some reason i cannot understand, the airpods pro play a really loud low battery noise, even if you are playing

music at the quietest volume and so many times, i've fallen asleep with these in, and then suddenly... battery alert noise it makes mejump out of my skin every time. apple, please fix this. but that is a small issue compared to the hissing on the pixel buds. google says the hissing is rare, and it will fix it with a software update, but these first came out in the us in april and it's still not fixed, so i suppose we'll have to wait and see. after months in isolation the idea of coming to a bustling airport, let alone getting on an actual plane can be slightly unnerving. here at heathrow things are quieter than usual, but they are doing everything they can to try and make the place covid safe with a fair bit of help from technology. let's go and take a look. these robots were previously used to kill off hospital—acquired infection, but now there is one in each terminal employed to disinfect. nothing, it is focusing on the

most common touch points. it uses uv light, and viruses don't have the resistance and immune system to uv, so you could say it kills the virus. the only way we could see it working was through the window of this conference room. there is a good reason we couldn't go in, for the first few seconds that it is on, the room smells of burning skin, apparently. so, to avoid any nasty burns, it needs to get its work done when no one is around. its motion and vibration sensors double—checking that no—one has appeared unexpectedly. but at least it is pretty speedy. in the airport, this robot can disinfect 18,000 square metres in a minimum space of two and a half hours. it disinfects, not cleans, so it is nice to send this into a washroom, disinfect it, then it is safe for the cleaning staff to go in, then they can clean.

in an airport it is notjust about cleaning overnight. a place like this is usually pretty busy and that means that people's hands going on the same surfaces quite a lot, especially somewhere like an escalator. the solution here could also lie in uv light. this escalator has been retrofitted with one underneath the belt, so it means that every time it goes round, it is being sanitised. and the whole route we take through the airport seems to have been carefully considered. stickers on lift buttons, wrappers on escalator handles, so think about your antibacterial spray but from a virus point of view. you wrap that around the escalator handle and it basically gives you several months of virus—free touching, and what we do is we have a technical check that we can make, our bio technicians do this on a regular basis to see what the viral load is on those touch points, they can make sure that that wrapper is

working and fully functioning. it is used in a number of different places. we have them on lift buttons, escalators and also importantly on trolley handles. there is also a mandatory mask wearing, and other safety features are being trialled, like this camera detection system tracking people's temperatures. the only thing that seems to be missing right now is somewhat unsurprisingly, the passengers. that's really interesting stuff. i suppose the big question is, with all of that make you feel safer about flying? exactly. it would certainly make me feel safer about being in the airport, but then i got to get on the flight, and you could think about using some of these technologies on a plane, obviously before the passengers got down, but you still don't want to be sitting next to someone who has got coronavirus.

good point. cheers, mate. we will see you in a bit. now, are you counting down to the next generation of video games consoles and will you be team xbox or team playstation? that decision often rests on the exclusive games and franchises that each offers. the sony line—up for the ps5 has written received universal acclaim from the gaming community but nothing xbox has revealed has set pulses racing but all that could be about to change, thanks to the biggest franchise xbox has, halo. halo hero the master chief is xbox's not so secret weapon in the next generation console showdown with playstation. the new game, halo infinite has action centred around the master chief, tackling a bad—tempered space bad guy

who leads the distinctly unfriendly sounding banished. i sat down with bonnie ross, head of things halo at microsoft and phil spencer of xbox to talk about the master chief's next gen outing. as far as the next gen consoles are concerned is it that graphics so sharp you can see sweat on the brow of an alien before you dispatch them with zero load times or is there more to it than that? obviously you have got ten times the processing power, but for us it is about the universe, and the suspension of disbelief. we have spoken before about agency, how players chosen as one of those things that really connects you to the story. you now have more choice in the decisions that you make as master chief, which i do think, in the long run, it is a mechanism

for connecting you more to the story that is there. halo infinite is arguably the biggest and most important launch title for the new xbox. to date it has generated about £5.5 billion in sales, shifting 77 million copies across the franchise lifetime. the first halo combat evolved for the original xbox back in 2001, developed by bungie it combines storytelling incredibly lush visuals. successful sequels followed before the developers bungie departed the microsoft games studios and on to make their own sci—fi looter and shooter, destiny, which left 315 industries to produce halo four and five, both commercially successful games which had a mixed response from fans.

i think with halo four we told a beautiful story, i'm proud of what we did with campaign, but we fell down on content, we are probably trying to do some me too, trying to focus on what other games were doing versus thinking about halo. with halo five it is like we reversed our learning. i think the halo five story is a fine story, i think it is a great halo story with master chief at the focus, and in multiplayer, i'm incredibly proud of what we did. so, first time up at the back, i hope that we are learning together and making sure that we get it right this time. it is a new game on a new console so the master chief has a new kit to play with including this, the grapple shot. and at the drop shield which provides master chief with temporary cover.

plenty of old favourites, of course, return. halo infinite wasn't the only next series xbox game microsoft showed off, and the standouts included a new fable title from playground games who previously brought us, forza horizon, and there's a new forza game with visuals so sharp they should carry a health warning. on this evidence xbox seems to have got some of its mojo back. we will find out if it is enough to face down the challenge playstation 5, when xbox series x launches later this year. that was mark. looks like the next generation console war is hotting up. that is it a must for the moment. from me on the sofa,

and from lara at arrivals. you can keep up with our team throughout the week on social media on youtube, facebook, and instagram. thanks for watching, and we will see you soon. goodbye. we haven't seen any prolonged, settled summer sunshine for a long time now. the next couple of days stay pretty unsettled by the rain or showers and unseasonably windy for the time of year but for wednesday onwards, high pressure builds in quietens things down for a few days at least with temperature warming up in the south. so far today, the strongest of the winds and rain have been through scotland. a cluster of

showers further west. some of these will drift further inland throughout the remainder of the afternoon. sunny spells and scattered showers to close out sunday with temperatures peaking between 14—23. to the evening some of those showers will start to fade away but there is another area of low pressure going to push on from the south—west and thatis to push on from the south—west and that is going to bring a spell of wet weather. particularly across parts of north wales and north west england. this area of low pressure will drift its way steadily north and east on monday. the strongest of the winds on the southern flank of that low as well. we could get an inch or two inches of rain across north wales, north—west england for a time. the rain pushing its way into scotland. somewhat fragmented light and patchy rain moving to the midlands and south—east and you have got that when the wind strengths, too. gusts widely close to 30 mph, may be a0 mild an hour plus in some thatis may be a0 mild an hour plus in some that is unusual, really, for the end

ofjuly and that is unusual, really, for the end of july and leaves that is unusual, really, for the end ofjuly and leaves the temperature is disappointing. mid to high teens in the north and may be 21 degrees down to the south. now, moving out of monday into tuesday, a quieter day. sunny spells and a few quieter showers but when direction sweeney ma ntle showers but when direction sweeney mantle north—westerly. not a particularly one day, really, 13—16 for scotland and highest values if we get some sunshine of 21 degrees in the south—east. as we move into wednesday here is that area of high pressure building for a time at least low pressure is trying to move then click on its heels but before that we will start to drag up some warmth across the south so we could come across parts of southern and central england, see temperatures into the high 20s, maybe 30 degrees and we haven't actually had 30 degrees so far this july so certainly a better end to the week with a little bit of patchy rain arriving back into northern ireland on sunday.

good afternoon. the government has defended its decision to re—impose a 1a—day quarantine for travellers entering the uk from spain, following a spike in the number of new cases in the country. europe's biggest travel company, tui, has cancelled all holidays to mainland spain for the next two weeks, after foreign office advice against all non—essential travel. charlotte gallagher has the latest. just in time, these people board one of the last flights out of spain before that midnight deadline. some passengers made

it back to the uk
