president trump has visited the washington church damaged by protesters. his walkabout came after he issued a warning that he will deploy the army to end the widespread demonstrations. across the country. they were triggered by the death in police custody of the un—armed african american man, george floyd. protests against police brutality are continuing in dozens of american cities, despite the impementation of more than a0 curfews. the official post—mortem examination has declared mr floyd's death a homicide. derek chauvin, the officer seen kneeling on the victim's neck before he died, will appear in court next week. the music industry is to observe a day—long blackout on tuesday, in response to george floyd's death. a number of major record labels, have announced they are suspending business, and working with communities to fight racial inequality. some artists have also cancelled radio appearances and media interviews.

england has seen the biggest relaxation of the lockdown since it was imposed 10 weeks ago. there has been criticism from some scientists that this is too much too soon. with the latest — here's our health editor hugh pym. enjoying new freedom in england today to meet outdoors in larger groups with social distancing. the rules in wales changed today as well. scotland and northern ireland have already loosened the guidelines on meeting outdoors. so as the restrictions are eased, how will the authorities monitor the spread of the virus and try to keep it in check? a full testing and contact tracing system is seen as essential. as well as testing people, ministers say tracking down recent contacts of those who test positive will be vital to stopping the spread of the virus. contact tracers have been appointed and the system launched, but already there are concerns. one contact tracer who wanted to be anonymous told us he had been given very little work since the launch last thursday.

we've heard reports from some contact tracers that, since they started work in england last thursday, they've had very little, if anything, to do. what do you think is actually happening with the system? we've hired, as you all know, 25,000 people to work as contact tracers. and the level of incidence of disease has come down. so actually, we have more capacity than we need. this is a good thing. they were pressed for the numbers of people so far contacted and said those figures would be available soon. then there's the r — that's the virus reproduction number. this shows how fast the virus is spreading. anything above one is when an individual is infecting more than one other person.

the aim is to keep it below that, which means the virus is receding. the latest official estimate is a range between 0.7 and 0.9, which doesn't leave much headroom. data on infections and deaths will be closely scrutinised. the daily number of new cases has been falling. the line shows the rolling average — that's the trend — though that does not include people who have not been tested. that's thousands more. the figure for reported deaths has also been coming down steadily, but the rolling average has stalled in the last few days. in the last week or two, we have seen a relatively persistent steadying of the death numbers and a very long tail of this epidemic curve, if you like. we'll be watching closely to see if that is maintained and persistent or if even that increases in coming weeks. an extra a45 deaths have been added to the total because of delayed reporting in previous weeks. 0ne health leader has said this is a dangerous moment — and easing of lockdown measures should be painstakingly slow,

as scientists watch developments. hugh pym, bbc news. now on bbc news, it's time for click. this week, who's tracking your teams‘ computers? how taiwan is tackling covid with tech. and finding cuddly koalas with drones. hello, you. hope you're doing 0k. the weather's getting warmer here which means only one thing — any minute now you will hear my next—door neighbour's lawnmower whiz past and there's nothing i can do about it. sorry, lara. there is an app for that, you know,

don't you watch a programme called click? oh yes, i remember. good point! we were actually all meant to be outside this week at the hay festival, but alas it's not happening this year. yeah, i know. i'm going to miss the hay festival this year. hay is still online though and they've got loads of speakers who are giving talks from their homes — rather like the rest of us these days. yes. how are you finding working from home, spencer? um, well, i'm really lucky to be able to work from home, but the weird thing is, whenever i have worked at home in the past i have worked harder and longer than i have in the office, basically because i'm paranoid people will think i'm skiving off. yeah, i can understand that although, of course, not everybody‘s that conscientious. and speaking to a lot of friends i think the idea that moving forward many of us could be working from home more, even after the pandemic. well, while our bosses can't watch us in the way they would in the office there is some technology that might. with millions of us now working from home, managers are facing new challenges.

homeworkers are harder to monitor and so trust is vital. however, in recent weeks demand for software to monitor employees has surged in the us, so it seems not everyone is quite so trusting. while companies may argue that it's simply about maintaining productivity, others may feel that we're slipping into a time of creepy surveillance. so based on these concerns, new york times journalist adam satarino decided to conduct an unusual experiment. i wanted to see how this employee monitoring software worked. and so i thought the best way to do that would just be to turn it on myself so i downloaded the software on my computer, on my phone, and then i turned it around and gave my manager, my editor in san francisco access as well, just knowing that your supervisor was looking over my shoulder and could see screenshots of what was

on my computer screen, or a log of what websites i was visiting, that sort of change how you behave and how you perform yourjob. adam used monitoring software hubstaff. the software is now installed on over 100,000 company machines. it can snap screenshots of your computer every few minutes. other software on the market can even record your screen — and monitor every keystroke. i really did begin to feel that it was intrusive and over the top. it spits out this percentage which becomes kind of your productivity score that can be used to measure you. and so mine were always stubbornly low, which was surprising, i consider myself to be a fairly productive person. i am embarrassed to say i looked at that number and i was like, what?

what is going on here?! it kind of raises immediate questions — like what is this guy doing? so i should have known better, because when he explained that this really only measures the amount of time you're, you know, typing on your device and using your device and your laptop, that explained a lot. but knowing what else he was doing felt really weird and intrusive. and it was kind of gross, you know. it's like you're not only violating adam's privacy, you're sort of violating other people's privacy that he was communicating with by extension. adam's experiment was one manager monitoring one employee and the companies providing the software argue that this isn't a true reflection of how their customers use it. but that's not the reality of what really happens. what really happens is i have 100 employees and there's nobody who's going around looking at the detail of 100 employees. so really what they're looking for is just those basic insights that we talked about. and the detail is just there if it's needed, if something looks off, looks awry.

however, in the united states the sudden surge in demand has started to draw attention to the lack of legal protection for workers' privacy. and also, highlighted a power imbalance between employers and employees. governmental action is necessary to protect workers from being forced to treat their dignity in the employment bargain. in february, i did testify in congress in the subcommittee on labour and education, and this was an issue that was raised. this productivity tracking of employees and also the fate of the data that is collected. with millions more of us now working from home, dr ajunwa concerns have become even more pressing.

she told us that currently employers are currently allowed to secretly monitor employees as no federal law exists that requires them to inform their workers about surveillance. it's now a free for all. it's the wild, wild west. everybody is now subject to the same kind of minute monitoring as we previously thought was, you know, the plight of those poor factory or warehouse workers. and there's also the issue of employment discrimination that can arise from all this data collection. if you're taking screenshots, you might discover information about the employee that you perhaps would not have discovered in a traditional workplace. you might discover that the employee is of a different sexual orientation, so that could also give rise to discrimination on those grounds, or a different religion.

but in europe, where productivity monitoring of employees is still legal, there is much tighter oversight, and there are regulations around its use. in europe we have to tell people what we're doing and why, and ensure that we have lawful grounds for doing that. if an organisation has a legitimate interest in collecting the data for workforce productivity in certain areas, then it will be able to do so without consent, but it will still need to be transparent with its employees, telling them what it's doing and of course putting safeguards to protect the data. maybe we will see this sort of employee surveillance become the norm, but clearly it will stir quite some debate. after all, how would you feel if your boss was monitoring you? hello and welcome to the week in tech. it was the week that,

for the first time, twitter restricted access to one of president trump's tweets, saying it glorifies violence. it's the latest move in an escalating row between the president of the social media company over censorship and freedom of speech. a canadian court ruled that the case of senior huawei executive meng wanzhou, who is fighting expedition to the united states, can go ahead. and if 10,000 songs was not enough for your lockdown listening libraries, music streaming service spotify has now removed that limit. you can now save an unlimited number of tracks and dance like nobody‘s watching. if you're getting square eyes in lockdown, how about upgrading to a holographic 8k display? the display, developed by looking glass, has a massive 33.2 million pixels and is designed to give the appearance of 3d without needing glasses. although a little less likely to happen to you at the moment, when you next find yourself out at sea, would you trust an algorithm to help you if you went overboard? researchers at eth zurich and mit

developed the algorithm to help speed up search and rescue operations, by more accurately predicting where a floating person would drift. and finally, while some of us have been struggling to fill the free time inside, one developer built a robot companion to keep him company. engineer sharath naik created ewon using a raspberry pi powered by google assistant. ewon can detect and show emotions but can't currently follow you around the house. now, as lockdowns are starting to ease we're also beginning to see the economic consequences. and questions are being asked as to whether covid—19 could have been handled differently. well, one part of the world that managed to keep things business as usual, more or less, is taiwan. with direct flights to wuhan and densely packed cities, the strategy promised

to be a disaster. but no. by the 20th of may taiwan had had just seven covid—19 deaths. so where did all go so right? back in 2003 taiwan faced another epidemic which also originated on the chinese mainland — sars. this time around, the government immediately began testing and tracing specific parts of the population using, for example, travel data to see who'd just returned from wuhan together with health data pointing to those with recent health problems. those who were quarantined were monitored using location data from their mobile phones. the virus was stopped in its tracks before it had a chance to take hold in the community. so soi

but how did this democratic island persuade the people to allow such use of their data? well, last year we met taiwan's digital minister audrey tang who was part of the 2014 sunflower revolution, in which citizens stormed the parliament buildings demanding to be listened to. among the protesters, civic hackers like these who worked together using open data to solve issues in the public interest. they've since come up with transparent ways of giving ordinary people a bigger say in making decisions. after that occupation at the end of 2014, the entire cabinet started to learn the art of listening and skill. and today listening continues. so when a citizen reposted a warning from whistleblower dr li wenliang at the start of december, people took note. and so because of this we were able to gain precious time to set up the centre, epidemic command centre, even before we had the first confirmed local case.

along with strong messaging about hand washing and social distancing, taiwan was keen to emphasise the benefits of wearing masks. in taiwan, people care about each other. and we build masks as something that, a, reminds you to wash your hand properly and, b, protects you from touching your mouth. and that is the main benefit of masks — to the person who wears it. while shunning of course we know once a majority of people in the same place to start wearing medical masks, they start protecting each other. the peer pressure only takes effect if a majority of people in a room wear a mask. mask production was ramped up from 2 million to 20 million a day and, to combat panic buying, they were rationed. then the hacking community stepped in with a series of real—time mask

maps to show the nearest points to you where they were still available. as maps became more popular, more volunteers came on board, and features like voice activation for the visually impaired were added. we trust the people a lot. sometimes the people trust back. and the people who trust back first gets their applications, their innovations amplified by the government into essentially civil engineering infrastructure. so that more than 10 million people use it in a participatory way to keep each other accountable. and here's another product of this higher level of trust between people and government. when rumours started to circulate online that toilet rolls were made of the same kind of paper as masks, toilet rolls started to run out. in response, taiwan's premier was enlisted to quash this misinformation with a meme. he shows his bottom wiggling a little bit and says that "we only

have one pair of buttocks each". and then a table that says the masks are produced using domestic material and tissue paper are produced using south american material and these two do not overlap. and this would absolutely viral. we make sure that these ideas travel faster than conspiracy theories, than rumours, by using cute dog memes so that the press conferences get translated by the spokesdog that explains hand sanitation rules, social distancing, mask use, and things like that and in many languages. and so this is literally our spokesdog and often go very viral. can you understand why not all governments think like you and, therefore, why populations don't trust their governments?

back when we encountered sars we had to barricade an entire hospital unannounced. there was no fixed time limit and that was barely constitutional. there was a severe trust crisis. and so we know how it was like because it was very chaotic. it's just that the entire society gets inoculated by that it experience. the important thing is that as a society we need to start deliberating about, for example, data use. the robust civil society takes control of most of the data applications or do you want a surveillance state or do you want the multinational companies to play that role? and that decision must be made by the entire society by the time that a next wave comes or a next mutation comes that will determine how your society responds to it. that was audrey tang talking to me earlierfrom taiwan. and now we go even further across the rld. yeah, see, a little while ago

nick kwek decided he had had enough of the uk and he moved to australia to explore the country. three weeks after he arrived he went into lockdown and hasn't left his apartment since. hi, nick. oh no. how's it going? hello! great to see you guys. yeah, it's been amazing. i feel like i really have managed to grasp what australia's all about from the inside of these four white walls. erm, i'm so glad that i moved from the other side of the world to now remain inside this cell. oh no! lockdown is easing there now, isn't it? i mean, are you hoping to start your touring soon? that's right. on monday the pubs are going to be open, so i'll be queueing immediately after this. oh, i bet you will be! now, before going into lockdown you did actually go to film some pieces for us, didn't you? that's right. well, i looked across the australian technological landscape and i thought what better way to start than go and cuddle some koalas or kangaroos?

and i wasjet—lagged anyway so i thought i'd pop out during the night. in the dead of the night something is afoot. two feet, in fact, and a jump. westpac little ripper group and myself are sleep to track down some roving roos or the occasional wandering walla by. we're not fussy. table, check, carpet, check, two unmanned aerial vehicles, check, check. i'm out with the same team behind the slick sharkspotter drones i've covered before. with the bushfires and the animals that have been affected we've now taken the amazing technology that we've out on the beaches for the last three years and we've put it over the bushland. now they've turned nocturnal and their new targets are considerably cuddly creatures. you can see kangaroo, kangaroo, kangaroo.

you can see they really stand out against the background. we're filming before sunrise during the coldest part of the day. so the new thermal cameras fixed to the drones can work properly. as well as being able to serve a huge swathe of land in the blink of an airborne eye, the drone's thermal capabilities can help in other ways. a thermal signature makes animals much easier to see at night. their natural internal temperatures making them visible even in the most dense of treetop canopies. and the different individual temperatures of the animals can be recorded, therefore making them more distinct between species. different animals show up at different temperatures. they have different fur that insulates them. so it's just a matter of picking them out so you can see quite easily that there's a whole lot of kangaroos in this field. we fly over an area and there's a kangaroo that seems removing a little bit differently, not as efficient as it usually would, not normal movement patterns,

then we'll focus on that. and if we bring the drone a little bit closer and they don't move and they don't scare or a human gets closer to them and they don't move or don't scare then we know that something is probably wrong with its health and we will focus on identifying that and passing that on to rescuers. dr grant hamilton from queensland university of technology is also using drones to monitor koalas. he's devised an algorithm to automatically detect animals in the outback using computer vision. 0n the right—hand side we have the artificial intelligence algorithm working and on the left—hand side we have the thermal imagery. it's a koala. initially it was falsely detecting kangaroos, for example, as koalas.

we were even detecting humans and even hot car bonnets. but that's the whole point that you go back and you retrain the algorithm. so the algorithm gets better and better and better to the point now we're better than humans are at detecting koalas. all of the algorithms that have been developed to date is processing back at a university, so there's no in field processing. so we're now going to work with the universities and the institutions, take their datasets and algorithms that they've started to develop, layer it over our technology, which enables us to do these surveys at night in the field and get real—time data back. and that's the key. someone who knows a thing or two about the state of australian animals is dr michael pyne. when i first started here 20 years ago we admitted just three koalas in the whole year and last year we admitted almost 600 koalas.

he sees real value in an up—to—date digital census. these surveys are done intermittently, maybe every ten years, and in many areas they're not done at all, it's just estimates. technology such as drones, you know, using those thermal cameras, can mean a large area can be covered in short periods of time, you know, relatively cheaply, to get those numbers so we know how many koalas are there and that makes all the difference. only if we know what's there can we manage what's there and be able to make, you know, decisions about the future. as well as the fires and the underlying issue of drought, chlamydia is a huge problem putting koalas under threat. so staff at currumbin have been using tech of their own to help diagnose the disease. we can take a swab, we can use this little unit here called the genie 3 and it will detect whether there's chlamydia or not from that swab within 25 minutes. so it's amazing technology that we can actually take out into the field, which makes all the difference to us being able to start treatment appropriately and at the end of the treatment,

you know, decide whether we've been successful with the treatment or not. a lot of work remains to be done and, in fact, it's the very beginning of the important work to find out what's left. the other thing to consider, though, is that this is just one bushfire season. and australia has bushfires regularly. so unless we get a good count now we're not going to be able to get any idea of what happens next time. that was nick, who, as we speak, is setting up a tent on the pavement outside his local pub ready for the grand opening. and that's it from us for this week. you can keep up with the team throughout the week on instagram, youtube, facebook, and twitter @bbcclick. thanks for watching and we will see you soon. bye— bye.

hello there. on monday, the temperature reached 28 celsius, and it was the warmest day of the year so far in northern ireland. and whilst it's going to be another very warm day for many today, the outlook is for it to turn much, much cooler. what's happening? well, we've been dominated by high pressure for weeks now, which has brought us the warm and sunny weather. the high is retreating into the atlantic, and to the north of that weather front, there is much cooler air. that cooler air will get swept down across the whole of the country later this week as a northerly wind develops. there is likely to be some rain around as well. now early morning, we've got rain across the far north of scotland. otherwise, it's dry, clear, temperatures typically 8—11. and once any early mist

and fog patches clear away from england and wales, it's going to be another sunny, warm day for many places. but we've got rain in northern scotland, where it's cooler, and we could see showers and cloud developing further south across scotland into the far north of england later, and also potentially in northern ireland. so here, temperatures will be 22 degrees. the highest temperatures are likely to be towards the southeast of england, say, 27 in the london area. it will be as windy as it's been over the past few days also. so we've got cooler air heading ourway. there's also going to be some rain in that cooler air, but it could prove rather hit and miss, and of course there were large parts of the country that were extremely dry during may. and we're uncertain as to how much rain there will be on wednesday across east anglia and the southeast of england. maybe a bit wetter across other parts of england and into wales, and probably largely dry in northern ireland

and the western side of scotland. but there will be a stronger northerly wind, which will make it feel cooler everywhere. temperatures are continuing to drop away, probably peaking at 20 degrees in the south east. and those temperatures actually are near—normal, really, for this time of year. given how warm it's been, this is going to be a bit of a shock to the system. move things to thursday, and those temperatures fall even further, perhaps a few degrees below average for this time in june. thursday, there'll be a lot of cloud around. it may not be quite as windy. at one stage, it looked like most showers will be in the north. now it looks like they're moving further south across england and wales. where's the high pressure by the end of the week? here, well away from the uk. we'll be dominated by low pressure, stronger winds, cooler air and potential showers on friday.

this is bbc news, i'm mike embley with the latest headlines for viewers in the uk and around the world. a warning from president trump that he will deploy the army to end the widespread protests across the country triggered by the death in police custody of the unarmed african american man, george floyd. if a city or a state refuses to take the actions that are necessary to defend the life and property of their residents, then i will deploy the united states military, and quickly solve the problem for them. in minneapolis, the official post—mortem examination finds the death was a homicide. the victim's brother tells demonstrators, violence would not bring the changes, the black community deserves.
