everyone can be a host on clubhouse. it is an audio — only social network where celebrities, entrepreneurs and pretty much anyone with an account can hold their own show. you can even drop into a discussion. what was the learning experience like for you to put that reduction together? it has had 4 million downloads in the last month and attract good $100 million worth of investment. find an event, topic or interview that picks your interest and go in. were free to stay silent and listen or even join in conversation yourself if you feel brave enough to raise a hand. after the chat ends, the room disappears and there was no option to listen again. let's keep going and have fun because it is a bleep up at the end of the day. now, of course, dropping in on unmoderated conversations means there is a chance of hearing something controversial or offensive is that it'll be interesting to see how harassment and misinformation is handled on an audio platform. certainly, there are technologies around audio monitoring and listening but deploying them, right, also creates a certain dynamic with the community in terms of, you know, these conversations are being recorded and tracked and all of that stuff. but clubhouse are not alone in the move to audio—based social networking and the tech giants are working on their own versions. facebook is set to be building a competing product but way ahead is twitter with this offering spaces. sometimes there is nothing more meaningful than to hear somebody�*s voice. i hope that because of that unique interaction between the text space, live nature of twitter, and the connection back to spaces that it will be big. how does anyone moderate audio? to do so with audio requires us to think about things like muting controls, being able to invite people to the conversation to speak and knowing when to have somebody say ok, time to pass the microphone. knowing whether or not you want to close a space so people can feel safe, depending on the nature of the topic, or make it more open to others. feel free to have a conversation about anything, even something controversial. but do so in a way that feels inclusive, respectful, and empathetic. the buzz around clubhouse and other tech companies getting in on the conversation shows at least there is an appetite for this format, certainly one talking point is that audio could signify the next game changer for social media. now, spence, something has been bugging me focal —— some travel to what is going on with your click sign? it is one that has been sent to me. this is a cardboard version of an important part of my life, the bbc micro. isn't it lovely? that's really cool.- that's really cool. both of these have _ that's really cool. both of these have been - that's really cool. both of these have been made i that's really cool. both of these have been made byi that's really cool. both of. these have been made by a former computing teacher now a stem champion who has been teaching technology in a very unusual way, teaching technology in a very unusualway, namely teaching technology in a very unusual way, namely using cardboard. hello, i'm alan 0'donohue! i'm here in my home at the cardboard museum of computing! for me, it started with this cardboard mac classic. one of the first computers that had a mouse with a graphic user interface. yeah, i certainly do remember the first apple macintosh computer, debuted by stevejobs back in 1984. so, i had no idea when i built this cardboard version that it might lead to some more cardboard computers, and then maybe even a whole museum? and this is just such a beautiful bbc micro. so i started making these during the lockdown, and i think it's a really nice activity to get you away from your screen, to be thinking about computers and technology, but in a different way. and if you fancy making your own models, then these paper cut—outs are available online. we have a microzbit, codebug, a memory device, an arduino. it's a very small, pocket—sized museum that people can download. and the inspiration seems to be catching. since i started sharing some of these projects online, other people have been inspired to build some themselves, just using cake or lego... inspiring technology doesn't have to be all coding and computer chips. we've got to be careful that we're not forcing too much technology on ourselves and our children. just spend some time unplugged, away from the computer, and see what you can create. though, i'm not sure i've got space at home for the largest piece in alan's home museum — a section of what's widely regarded as the very first programmable electronic digital computer. that's a lot of cardboard! but i do know where it lives in real life, over in the uk's bletchley park — alex humphreys has been to check it out. you may have seen bletchley park in the movies — yep, that one with benedict cumberbatch playing alan turing. of the codebreakers. beeping and whirring the uk's smartest minds, who, through sheer determination and extreme intellect, managed to break the secret code the germans used to send tactical messages from berlin to forces on the ground. this is the very latest, the bbc microcomputer... but i'm here to celebrate a different hero, perhaps one of education — the bbc micro. it's turning a0 this year! these computers were launched back in the �*80s, and the aim was to get kids programming. and it worked! it was so successful. and as result, many in the uk would have started on one of these. it was made by acorn computers, the so—called apple of the united kingdom. around 1.5 million units were sold. and thanks to a government subsidy, it went into more than 80% of primary schools in the country. tom is the man in charge of the bbc micro exhibit at the national museum of computing. he told me a bit more about why it was so successful. it had a very good programming language with it, bbc basic, and that meant it was really good in education and was used well by industry as well. it was one of the fastest industries about, for its time when it launched, so streaks ahead of the competition for a very low price point, really. ok, so i'm getting to play on a real micro. i am playing a game called chuckie egg. it's taken me about a quarter of an hour to work out the controls. this is so cool, i love it. but i'm not the only one playing. the museum invited gamers across the country to take part in the microlympics, giving players a chance to play classic bbc micro games on like repton, citadel, and elite on emulators online. a far cry from the likes of fortnite and roblox, but it gives kids a chance to experience what their parents might have played back in the �*80s. they're very different! like, the overall concept, and also the controls, you've got to be more focused. i normally play, like, games like mario kart, like, the graphics are quite different. it was a lot more simplistic and also like, the sounds. it was still interesting and just as fun. i find the controls quite difficult. - very. i thought they were quite random, like, you have 0, s, and t, which are far apart on the keyboard. thousands of kids and adults alike have since found inspiration for coding in its descendants, the bbc micro:bit, and its version 2, which launched in october. and so the legacy of this great british computer lives on. 0h! that brings it all back, it really does! chuckie egg, repton, elite, brilliant! seriously, the bbc micro is the reason that i do what i do today, and why i fell in love with computers. so, happy birthday, bbc micro, mwah! that was probably a bit much, actually. anyway, that is it for the short cut of clip this week. the full player version is available on a player right now. �* , y ., is available on a player right now. ~ , , ., is available on a player right now. ~' , now. as ever you can keep up with the team throughout the week and social media. one de sceaux youtube, instagram, facebook, and twitter @bbcclick. —— finds on. facebook, and twitter @bbcclick. -- finds on. thanks for watching. _ @bbcclick. -- finds on. thanks for watching. bye-bye. - hello again, we've got mild and windy weather as we head on into the weekend. but for some of us it's also going to work out to be pretty wet. we've got a slow—moving weather front across western areas, and along the front, pulses of thicker cloud, pulses of heavier rain working in. now, we are going to see those rainfall totals continue to mount up. always the heaviest rain over the high ground across western areas, we have a number of flood warnings in force in scotland, one or two for england, we've some enforced as well into wales and across the south of wales, the met office amber weather warning because through the course of saturday, over the hills, over the high ground, 100—200mm of rain is forecast, but of course all that rain falling on the high ground will work down into those river catchments and just increase the risk of seeing some flooding issues then into wales. and the rain here is pretty heavy at the moment as well, further north and west, something a little bit drier for a time in scotland and across eastern england. but it is going to be a mild start to the day, wherever you are, on saturday. so, for saturday, most of us will have at least some rain at times, it's going to be windy and mild, however, across parts of eastern england and perhaps central england as well, it looks like it's going to be brighter, hazy sunshine around and very, very mild indeed. so, real mixed fortunes from place to place. not a bad start to the day in scotland, probably a nice sunrise to start off across parts of eastern england. further west, the rain pouring down, the rain turning heavier for a time in north ireland, turning wet in scotland through the afternoon. now, temperatures for all of us will be on the mild side, 12—14 degrees pretty widely. however, across eastern england, 16 degrees or so is possible — very, very mild for the time of year. our weather front�*s still on the charts, then, through saturday night and into sunday, although the activity starts to wane somewhat, so the rain won't be as heavy and it will start to turn a good deal drier for scotland and northern ireland, with much more in the way of sunshine here for the second half of the weekend. it's across parts of england that we'll probably see some rain, perhaps starting to wiggle back towards wales, but it doesn't look like it will be quite as extensive or quite as heavy. another mild one coming up, another fairly windy day. again, it's across eastern england that we'll see the highest temperatures on sunday, highs of around 15 degrees or so. into next week, well, we've got another of these slow—moving weather fronts moving into western portions of the uk. so, again, there's a risk of some further localised flooding into the new week. this is bbc news. a reset for transatlantic relations as president biden recommits to nato and pledges to earn back europe's trust. america is back. the transatlantic alliance is back. and we are not looking backward, we are looking forward together. america's top diplomat speaks exclusively to the bbc about the biden team's approach to the world. whatever it is, not a single nation can reveal whether defectively. we have to work together.
