hello. this is bbc news. the headlines: the bbc has learned that a man detained on suspicion of killing the british mp, sir david amess, had previously attended a government scheme to prevent radicalisation. the suspect — named as ali harbi ali — is thought not to have been put on a watchlist of subjects, of interest to the security services. russia has recorded more than 1,000 deaths from coronavirus in a single day for the first time since the start of the pandemic. the infection rate has also continued to soar as the authorities struggle to persuade people to get vaccinated. tens of thousands of italians have marched through the centre of rome, calling fora ban on the neo—fascist forza nuova party. its leaders were among those arrested after the headquarters of the nation's oldest trade union was stormed in a riot a week ago.
now on bbc news, time for click. this week — hong kong is changing and so is its wikipedia entry, but who is responsible? bringing the vikings to life for schools. and, i mean, how many ljs do you need on a song? for many of us, wikipedia embodies the true spirit of the internet — an enormous source of information created, edited and policed by volunteers around the world. and while it's certainly possible to tweak an entry about yourself or your company to add some "facts", the encyclopaedia's community of editors and fact—checkers have been famous hot on dragging you back to earth should you big yourself up too much.
hmm. but over the last couple of years, we've uncovered evidence that some of wikipedia's articles are being changed to present a particular country in a more positive light — and that's china. you remember what carl millerfound when we sent him to taiwan? yes — articles about taiwan's independence were being edited to swing more in line with china's view. although carl did point out that these views are not lies — after all, who is wikipedia to override the opinions of many people in the most populous country in the world? well, now, a click investigation has found evidence that wikipedia articles about hong kong are also being changed to be more pro—china, and the situation has escalated to the point where wikipedia's governing body has suspended several pro—beijing editors for abusing the platform.
so carl and danny have teamed up to ask whether wikipedia's open knowledge goals are really compatible with a world where different countries have different views on the truth. stephen mcdonell: tear gas, which is being fired. _ you can see from above behind them, the riot police have these two water cannon trucks. in hong kong, beijing has been clamping down on descent since the start of the protests in 2019. the clashes between the police and pro—democracy demonstrators may have subsided for now, at least. but the same cannot be said for the online world, where the battle for the narrative still continues. furious edit wars have been raging behind the scenes on wikipedia between pro—democracy and pro—beijing points of view. our team of investigators have spent weeks looking into these edits, mostly in chinese languages but also some in english. this article is about the yuen long attack in 2019 which saw about 100 men wearing white shirts attacking people in a transport station.
there were allegations that these men both had triad connections but were also in cooperation with the police, ultimately backed by beijing. but on the chinese wikipedia page of the incident, the second of these pictures was removed and then two days later, well over 100 further edits was made to the page. changes were being thrown back and forth between words such as �*rural factions�* to �*terrorists�* or �*conflict�* replacing �*terror attack�*. but worst still, the edit wars seem to have taken a nasty term — there are reports of threats being made to editors who are contributing what are at least seem to be pro—democracy edits. messages on private chat channels were designed to strike fear, which led to seven pro—beijing editors being banned from the site, some for the threatening messages and some accused of propagandising in the chinese narrative. these are edits that usually look at the event from a western prism and what chinese editors deem biased.
but to get a sense ofjust how real the situation is on the ground right now, we asked our bbc hong kong correspondent danny vincent to dig deeper. i met someone we�*re going to call �*john�*, who continues to edit articles on wikipedia relating to important events in hong kong�*s recent past, so a balanced viewpoint is presented. we gathered in a neutral location and under the cover of darkness. since the introduction of beijing�*s national security law, wikipedia seems to have become a much more hostile place. pro—beijing people often remove content that is sympathetic to the protests — tear gas being fired, image of barricades and the like. they also add their own content. pro—democracy editors tend to add content to shift the balance or the tone of the article. but in my experience, the pro—beijing editors are a lot more aggressive in droning up this information. it�*s now unfixable without external interference because they are
trying to rewrite history. while these editors may use state—registered e—mails and vpns to get across the internet that�*s otherwise banned in china, john says it�*s not a straightforward situation of beijing ordering the edits. there seems to be an overflow of patriotism in china and these changes are being carried out by people loyal to the communist party, but they are not paid for by the government and they are not all based in china, either. and in contrast tojohn in hong kong, there are others continuing their work editing wikipedia articles both in english and in chinese, but importantly from the safety of another country. �*dave�* lives in britain but as a pro—democracy editor, he fears for his family and friends back home, so he spoke to us anonymously. when i started doing my edits, pro—beijing
editors were ganging up to undo my edits. when i took my concerns to a higher level in wikipedia, the pro—beijing editors tried to use their numbers to crowd me out, so my voice did not get heard. we put all of this to wikimedia, the foundation responsible for wikipedia, to ask just how long they think the largest encyclopaedia can survive when it�*s become a battleground. we come at it from a very, very hardcore ideological perspective about neutrality, about freedom of expression, about quality, and we�*ll stick to that, and we�*ll stick to that no matter what. wikipedia�*s global. wikipedia is not localised to particular countries. as soon as we identify someone who is not behaving appropriately, we ban them, so it�*s quite simple. and that is exactly what wikipedia did last month when it banned seven pro—beijing editors. we tracked down yan,
one of them. he lives abroad now, but used to organise events in china, teaching citizens there how to edit wikipedia. he denies misusing the platform and says that the removal of active pro—beijing editors is detrimental to the neutrality of wikipedia as a whole. wikipedia, especially chinese wikipedia, is a balance that anti—beijing forces and the pro—beijing forces must maintain a balance and people agree on a compromise in order for the project to proceed. and the thing is you�*re removing one side from — you�*re removing the pro—beijing voices for — from this platform and of course, the balance is going to tilt towards the anti—beijing forces within wikipedia. as it turns out — and i have deep experience talking to people all over the world and meeting wikimedians — the idea that people in china, for example, are so brainwashed that they can't even conceive of the idea of neutrality is just completely false. so many people are able to say "ok, here's my view of the world, but i understand there are
other views of the world and that an encyclopaedia should present an explanation of all these various viewpoints ina fairway. the way wikipedia works is that while anyone can edit an article, higher—level administrators act as the ultimate decision—makers. they are vetted and elected by a community of writers within each country, which wikipedia says is crucial to preserving the integrity of the people�*s encyclopaedia. but yet, in recent weeks, 12 administrators from mainland china have each had their wikipedia privileges revoked. those administrators that were elected fair and square, even years ago or decades ago, they were elected by the community. from yan�*s perspective wikipedia is still missing the beijing viewpoint, so he is setting up an alternative to wikipedia in china — albeit one that will be censored. we are going to do — basically use all wikipedia�*s content — chinese wikipedia�*s content — and we build a mirror site, we build a fort
of wikipedia in china. it is going to be better than wikipedia�*s current competitors in china because we are providing unintelligible information from just unintelligible from wikipedia in china and people will have a better platform to actually write about encyclopaedia articles. the biggest thing that's preventing mainland chinese people from expressing the viewpoint of mainland china's people is the chinese government who don't allow them to edit wikipedia, so the idea that we are somehow excluding china is absurd — we welcome with open arms our editors from china. hello and welcome to the week in tech. it was the week that the us became the world�*s largest bitcoin miner after regulations banning the practice have taken effect in china. defence company ghost robotics added an assault rifle
to a robot dog. and australia�*s space agency announced its first mission to the moon. it will collaborate with nasa on building a 20kg rover to collect lunar soil containing oxides. separate equipment will be used to try and extract oxygen. another space news this week, star trek captain william shatner became the oldest person to launch into space. the nonogenarian was a passenger aboard jeff bezos�* blue 0rigin rocket. it�*s the second successful crewed trip into suborbital space for the company this year. flying taxi firm vertical aerospace says its cars will be in the skies in the uk by the mid 2020s. the mini aircraft are emission—free and would be able to transport four people at a time at speeds up to 120 miles an hour. artist anicka yi�*s new exhibition was unveiled at london�*s tate modern museum. called in love with the world, it features robot sea—like creatures called aerobes floating around the human visitors. the exhibit is open till mid january next year. and finally this week,
another robot sharing space with humans, this time in california. meet leonardo, or legs on board drone — leo for short. researchers at caltech wanted to create a bipedal robot that can jump and fly to develop a new form of locomotion. leo can also ride a skateboard and walk on a slack line. the right music makes things better. it can change our mental state, add emotion to movies and and even help us move when it is hard to keep putting one step in front of the other. yet while so many of us consume music, playing an instrument feels out of reach. but you no longer need 10,000 hours to create something beautiful. you just need a different kind of instrument.
# this is the harmony engine, adding layers of extra vocals # to my voice in real—time. the program first recognises which note i am singing, and then adds layers based on music theory or even user input. the company who makes this are behind autotune, which is everywhere and pop music, and if you have ever listened to a billie eilish song, you have already heard it used to great effect. # what do you want from me, why don�*t you run from me... that sounds familiar. this is the thing, though. i didn�*t realise that was technology! you analyse the pitch of the song you are singing it, you slice of your head, and then put the head back on. that is really how it works in a kind of silly sort of explanation. the new product, autotune slice has only been out a week. it automatically cuts a vocal melody into a playable musical
keyboard. but is all this tech taking too much skill out of music creation? musicians and recording engineers who understand every aspect of the recording process, and those guys are probably rolling their eyes, laughs, "we had to learn all this stuff, and now companies are trying to make tools so that they don�*t have to do the hard work that we did, to learn our craft, learn our trade." if you are more of a drummer than a singer, dubler might hit the spot, using al to learn your version of different bits of a drum kit. now you have to train the system by recording a few takes. ts—ts—ts—ts — that�*s my hi—hat. and now dubler knows roughly what i mean with different drum sounds turning my enthusiastic though amateur beatboxing into a full drum kit. beatboxes.
unlike many music plug—ins, dubler also works without needing any external audio software, though it does work with digital audio workstations. this is the newly released uno synth pro, which glories in its analog sounds, juicy and rich. which, at around £550 or $750 for the desktop version, might prove a bit too rich for a beginner. though it is easy to make something sound good with very little effort. so here we go. synth arpeggio plays. nice! and you can change the feel of the sound by using these bits. sound changes. lowering the barriers to creativity can help musicians who struggle with mobility. like yurina, an avid pianist who is connected to a respirator and unable to leave her house, so she is controlling this grand piano at yokohama city hall remotely. it is part of a project between
yamaha and tokyo university of the arts. when yurina presses a key, the auto—accompanied piano plays along with her. she practised playing her side slightly ahead of time, as it takes about 100 milliseconds for her piano signal to reach the concert hall. none of these new creativity tools detract from the massive benefits of learning a physical instrument. in fact, i think they complement each other. technology at its best, giving the gift of music to everyone. most of us have had our lives impacted by cancer in some way. i have, i know that you have too. but it can be tricky to support someone you love going through it, because you cannot necessarily really understand what they are going through. but one app is hoping to help by creating a community of cancer patients to be able to share theirjourneys.
reielle was diagnosed with a rare form of cancer back in 2019, and has since undergone operations, chemotherapy and ivf egg collection. sometimes i feel lonely because i am literally one in a million. this spring, reielle started using a new app designed for cancer patients. i knew instantaneously it would be a place where i could message people, we could connect and communicate, and that is what i really needed. the day before i started chemotherapy i was a bag of nerves, and i turned to the app and then i had loads of messages of encouragement and support. i ended up asking a lot of questions to people, has anyone had this happen to them. i spoke to a lot of girls about getting manicured, sometimes you can lose your femininity and bring that back is amazing, it is what i need. alike was launched by two—time cancer survivor brad gudger. over 1500 people have
signed up so far. the problem with relying on pre—existing social media is you cannot find people. alike takes the best bits of a social media platform and repurposes it specifically for the cancer community. you can filter based on age, and in future we want to enable people to filter based on location, providing something that can be with you right through diagnosis, treatment, recovery and in some cases with people at the end of our lives. many are keen to keep up with the latest research as well, but this can be challenging as new findings shared by academics or medics can be hard to decipher. and that�*s where medivizor comes in. a service that scans the web, translating the latest studies into patient—friendly email updates. when my late mother was diagnosed with cancer, i was amazed that the plain
english availability of accurate, timely information was really horrible. so how does the process work? i take it you have a team of people who are collecting all this information and translating it into something people can understand. it�*s a combination of algoriths that are crawling the internet. prioritising information based on what is important, and also people assisting the machine to refine this conversion from scientific language into layman, or almost layman terms. the basic service is free for patients but the company is funded by paid versions, including one for private doctors. taking matters into your own hands, though, can have its downsides. of course the important thing is recognising that at that time they are most vulnerable. so where information is quite empowering, you have to make sure it is the right information, notjust based on an algorithm which could unfortunately scare
the patient sometimes. because two people could have cancer, and have different concerns about their cancer diagnosis. i don�*t know about you, but my kids are having a completely different school experience to the one that i had when i was young. how about you ? theyjust seem to be able to do teaching so much better these days. mm, maybe there isjust more weight being given to the idea that different children learn in different ways. i think you are right. and in fact some kids, my boy included, learn really well through computer games. and i expect marc cieslak would have done too. since 2007 the assassin�*s creed videogames have allowed players to bump off bad guys throughout periods of history as varied as renaissance italy to ancient greece. the most recent entry in the series, assassin�*s creed: valhalla, transports the action to the ninth century as vikings attempt to settle in britain, something that doesn�*t go down that well with the locals.
valhalla�*s developers have worked really closely with historians and archaeologists to ensure historical accuracy and real locations like this one, portchester castle on england�*s south coast, appear in the game. we tried to research the kind of people we would meet there but also their habit, the way they would talk, the way they would live their daily lives. i tire of raiding, harold. and the idea is notjust the aesthetic but also philosophical, what are their thoughts of the period, what are they looking for in their daily lives? but what do you do with all that research and work, after it�*s been put to work building the world in the game? the developers have removed the violence from the game, replacing it with quests which are designed to allow the player to gain greater historical insight about the period. valhalla is the third assassin�*s creed game
to feature this element, called discovery tour: viking age. we must exit the fjord, sail right. how did you approach the discovery tool, was it a case of taking the weapons and killing out of it? i think the idea is that people can enjoy these locations while learning about them. we have created these quests that are basically around empathy, because videogames have a strong component to make people learn, because we feel what our avatars and what the characters are living through. then i shall observe and hopefully learn some new tricks of my own. one of the most famous viking settlements in the uk was in york, and it is here we find thejorvik viking centre, home to a vast array of period artefacts — some of which provided inspiration for the developers. and it�*s here we also find writer and broadcaster danny wallace, who has had a long association
with the assassins creed series, providing the voice of one of the game�*s characters, historian sean hastings. hello, am i speaking out loud, hello? i think back to my history lessons at school, and a man or a lady would stand up and talk to me for a very long time about crop rotation or spinning jennies. and all i can remember is that you have to leave one field fallow, that is very important. however, thanks to kind of getting involved in these games, you find yourself engaging with those worlds much more. so if you suddenly see something and it catches your eye, and you are like, "i wonder how they made shoes," or "i wonder what they ate", you can go over there and you can find out yourself. the discovery tour will find its way into classrooms and 52 schools across the uk. as a result of the collaboration between the game�*s publishers ubisoft and ukie, the british games industry�*s trade body. ukie�*s educational arm digital schoolhouse will see this version of the game used as a teaching tool across a wide variety of subjects including history, art, english and computing. most teachers will agree,
that when you are teaching children, passive consumption of knowledge has limited retention value long—term. the best way to get children to learn and to develop a deep and full understanding, which they can then apply later on down the line, is by getting them actively involved in doing something that is engaging. do not lose your course through the storm! so in the future, when we want to learn something, as well as consulting a book or research with the help of the internet, some of us mightjust pick up a games controller as well. where am i? jotunheim! i wish history was taught like that when i was at school, i would have been brilliant at it! i know, it reminds me of when i tried to learn a language using a mind palace in virtual reality, in 10 minutes i learned so much more than i could have done in a lot of time doing it normally. fires a different part of the brain, doesn�*t it? go on, say something. speaks spanish. anyway, that is it
from us this week. as ever, you can keep up with the team on social media, find us on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching and... speaks spanish. bye! hello there. we�*ve got some cloudy and damp weather around for the first part of sunday. quite a contrast, then, because we got some decent sunshine through saturday, the best of it across southern england, the midlands, wales and east anglia and the far north of scotland as well. but late in the day we did see some rain start to come down around the dunblane area. that really is the first signs
of this band of rain that�*s showing up on the radar picture, pretty extensive and heavy across northern scotland and england, getting into north wales as well. and even further southwards, over the next few hours a few patches of rain across the south of wales and south—west england as well, leaving across the midlands, east anglia, south—east england and some dry weather north of scotland for the next few hours. a mild start to the day on sunday. 11 to 30 degrees widely, a legacy of cool and clinging on across the parts of northern scotland, where it should be a bright start. but otherwise, extensive cloud to start the day on sunday, the rain initially heavy in scotland, but later and patchy quickly to the morning. but i think across northern ireland, scotland and northern england, these areas will be prone to spots of rain even into the afternoon, so for some it will stay on the damp side. but at the same time, we should start to see some gaps in the cloud opening out in the south with a few sunny spells in southern england, southern wales and the south midlands. for monday, we�*ll start to see some stronger south—westerly
winds moving in. so monday will be a windier kind of day, particularly across western areas, with layers of crowd and outbreaks of rain spilling in. not so much across eastern areas, but if you do see some sunshine, it�*s likely to be very hazy. there�*s going to be a lot of high cloud in the sky, so bright rather than sunny in those drier moments. temperatures will be mild, 15—18 degrees pretty widely, and it gets even milder still on tuesday. the winds coming from a long way south, but then we�*ve got this slow—moving weather front bringing some intense bursts of rain to the west. perhaps across wales, perhaps across cumbria. some of these areas could see localised surface water flooding issues. but again, eastern areas not seeing much in the way of rain, really. we could see some sunny spells breaking through. if that happens across the south—east we could see temperatures climb to 20 or even 21 degrees celsius. very, very mild indeed. that mild weather stays with us for the first half of the week before temperatures gradually get close to normal towards the end of the week.
this is bbc news. welcome, if you�*re watching here in the uk or around the globe. i�*m rich preston. our top stories: a man suspected of killing the british member of parliament, david amess has been named as ali harbi ali. it�*s understood he�*d previously been referred to a counter—extremism programme. the prime minister and leader of the opposition paid their respects at the scene of the attack, as a review begins into the threats faced by politicians. russia records more than 1,000 deaths from coronavirus in a single day for the first time since the start of the pandemic. mass protests in rome, as tens of thousands of italians call for a ban on the neo—fascist forza nuova party, over its involvement in a riot a week ago.
