0:00:04 > 0:00:08AFRICAN MUSIC
0:00:23 > 0:00:24This week on Click,
0:00:24 > 0:00:28we're in Africa for the start of a global campaign using these
0:00:28 > 0:00:31to bring computing to some of the poorest areas on the planet.
0:00:31 > 0:00:37And we'll show you how you could use them too, to protect your privacy.
0:00:37 > 0:00:39We discover the secret formula to predicting how
0:00:39 > 0:00:43popular your snaps will be before you post them.
0:00:43 > 0:00:47And we travel to San Francisco to see how shoppers are tapping into
0:00:47 > 0:00:51the biggest brains on the planet to help them decide what to buy.
0:00:56 > 0:00:59Welcome to Click. I'm Spencer Kelly.
0:00:59 > 0:01:02As teched up as we are, it's important to remember that
0:01:02 > 0:01:06two thirds of the world's population don't have access to
0:01:06 > 0:01:10a smartphone or a computer. That's five billion people.
0:01:10 > 0:01:12And for those who do want to get online,
0:01:12 > 0:01:16bridging that digital divide can be really, really difficult.
0:01:16 > 0:01:19We've reported in the past on how charities are helping out
0:01:19 > 0:01:23in poorer areas but now, two colourful entrepreneurs think
0:01:23 > 0:01:26they might have found a solution which funds itself.
0:01:26 > 0:01:31Dan Simmons has been to Kenya to witness the first day of a global campaign.
0:01:46 > 0:01:50The slums of Nairobi are some of the largest on the planet.
0:01:50 > 0:01:54Mathare is home to around half a million people, and although
0:01:54 > 0:01:58most don't have free access to some of life's basics,
0:01:58 > 0:02:03they are interested in, and want access to, computers and the Net.
0:02:04 > 0:02:09To grow, information is one of life's basics, and it's arriving here
0:02:09 > 0:02:13in a way and on a scale that's not been tried before.
0:02:16 > 0:02:19So far, most attempts to bridge the digital divide have
0:02:19 > 0:02:24revolved around communities sharing refurbished PCs or tablets.
0:02:24 > 0:02:27But now, one group has come up with an idea that could
0:02:27 > 0:02:31see 150,000 people here own their own computer.
0:02:31 > 0:02:35And it's all down to this, the humble flash drive.
0:02:35 > 0:02:40The mission starts today at a school somewhere down there.
0:02:48 > 0:02:50The WhyNot Academy has just been built.
0:02:50 > 0:02:53Like other schools in East Africa, it uses textbooks
0:02:53 > 0:02:59- and chalkboards to teach. - What is this?- Ears.- Ears.
0:02:59 > 0:03:04But in 2012 it was hooked up to the power grid, sort of unofficially.
0:03:04 > 0:03:07And now these two characters have arrived,
0:03:07 > 0:03:10it's been hooked up to the Net as well.
0:03:10 > 0:03:13The WhyNot Academy is officially connected to the internet.
0:03:13 > 0:03:15CLAPPING
0:03:21 > 0:03:23The makeshift solution, courtesy of a SIM card
0:03:23 > 0:03:28and a router hanging in a plastic bag, is classic Nissan and Franky.
0:03:28 > 0:03:32They're rough and ready entrepreneurs who just want to get things working
0:03:32 > 0:03:35rather than worry about how they might look.
0:03:35 > 0:03:38So they're making use of some cheap, old laptops too.
0:03:38 > 0:03:41This is now my Keepod.
0:03:41 > 0:03:46I use this little brain. But if Dominic needs now my computer,
0:03:46 > 0:03:49no problem. I take this out.
0:03:49 > 0:03:53He takes his Keepod, puts it in and starts working.
0:03:53 > 0:03:56They may not get the explanation first time round,
0:03:56 > 0:04:00but when the children are shown how they can say, "Hello, world"...
0:04:00 > 0:04:06- Hello, class!- ..interest quickly picks up. And everybody wants one.
0:04:07 > 0:04:12Next, headteacher Dominic hands out the flash drives which,
0:04:12 > 0:04:17importantly, each child gets to keep. It's why they call it Keepod.
0:04:19 > 0:04:23The laptops run directly from the small USB keys.
0:04:23 > 0:04:28No key, no laptop as they don't have a hard drive inside.
0:04:28 > 0:04:30In fact, any computer with a screen, keyboard
0:04:30 > 0:04:34and a basic processor will play the perfect host
0:04:34 > 0:04:37because each Keepod comes with its own operating system.
0:04:37 > 0:04:42This unique desktop version of Google's Android mobile OS
0:04:42 > 0:04:47makes any laptop or PC as simple to use as a smartphone.
0:04:47 > 0:04:51So whoever's USB or Keepod this is in here,
0:04:51 > 0:04:56whatever we browse will be kept on it so that next time they go online,
0:04:56 > 0:05:00they'll be able to go straight to where they were before.
0:05:00 > 0:05:01Obviously, you don't want to lose yours
0:05:01 > 0:05:07- or swap it out for somebody else's. - I see photos. Even, there's movies.
0:05:07 > 0:05:12- This is a new technology. Wonderful! - Talking to others, sending messages.
0:05:19 > 0:05:23Back in the office, another good piece of news comes in.
0:05:23 > 0:05:24This is calling the United States.
0:05:24 > 0:05:26They want to donate for the project.
0:05:29 > 0:05:30That's awesome.
0:05:30 > 0:05:33Even Arthur, the local PC repair man, is getting involved.
0:05:33 > 0:05:38He'll offer IT support and strip the hard drives out of the laptops.
0:05:38 > 0:05:42He can get up to 70 for these, so he's quite happy about it.
0:05:42 > 0:05:44They're using the Keepod.
0:05:44 > 0:05:46The first Keepods are being given away,
0:05:46 > 0:05:52but soon, they'll be sold for about 7 each, making a small profit,
0:05:52 > 0:05:54which should help pay for the project.
0:05:54 > 0:05:57It will help Africans help themselves.
0:05:57 > 0:06:00They are going to start to learn the skills of business.
0:06:00 > 0:06:04They are going to learn to read the story of people who have
0:06:04 > 0:06:06made it from nothing and through business,
0:06:06 > 0:06:10people who did not go to a lot of education but they made it.
0:06:11 > 0:06:13I mean, they are going to download viruses.
0:06:13 > 0:06:16They probably will download some sort of malware
0:06:16 > 0:06:18but it doesn't affect the hub that everybody uses.
0:06:18 > 0:06:20It's just the one individual.
0:06:20 > 0:06:24Anybody else can get on and carry on using things as normal.
0:06:25 > 0:06:27You are not allowed to put that on the Net!
0:06:31 > 0:06:35Backing up each Keepod is part of the plan but the steep learning curve
0:06:35 > 0:06:40and the economics of this inventive scheme will be a big test.
0:06:40 > 0:06:43Some fear the Keepods may be traded by parents for some meat to
0:06:43 > 0:06:48put on the table if they don't fully understand its potential value.
0:06:48 > 0:06:52And in many areas like Mathare, just getting electricity
0:06:52 > 0:06:55and then online will be tough.
0:06:55 > 0:06:58But here, the magic flash drives have arrived.
0:06:58 > 0:07:04Each owner feels like they have their own computer and the party has begun.
0:07:08 > 0:07:11Dan Simmons reporting from Kenya on the start of what could be
0:07:11 > 0:07:14a game changer for many.
0:07:14 > 0:07:16And if you'd like to get involved in that project,
0:07:16 > 0:07:20we're told that starter packs will be available to buy later this year
0:07:20 > 0:07:23which should allow anyone to supervise a version of that project
0:07:23 > 0:07:25anywhere they like.
0:07:25 > 0:07:28Now, while having an operating system on a portable drive
0:07:28 > 0:07:32like this isn't anything new, the ways of using it,
0:07:32 > 0:07:34like the Keepod project, are.
0:07:34 > 0:07:39And one reason you might want one of these is to protect your privacy
0:07:39 > 0:07:41because it's emerged that that's what
0:07:41 > 0:07:44CIA whistleblower Edward Snowden used his for.
0:07:46 > 0:07:49Last month, we discovered that Mr Snowden had been using
0:07:49 > 0:07:54an operating system called Tails, a version of Linux that,
0:07:54 > 0:07:58once on a flash drive or SD card, can be plugged into any computer
0:07:58 > 0:08:01and which makes it easier to go incognito on the Web.
0:08:03 > 0:08:07Tails includes super secure versions of common software.
0:08:07 > 0:08:09It uses high-level encryption for everything
0:08:09 > 0:08:14and accesses the internet via the Tor network, so wherever you surf,
0:08:14 > 0:08:18they'll find it much more difficult to work out who or where you are.
0:08:20 > 0:08:25Finally, it leaves no trace of what you were up to on the computer you used.
0:08:26 > 0:08:30Tails is free to download by anyone but before you do,
0:08:30 > 0:08:33you should know that, like any system offering security,
0:08:33 > 0:08:38it's not actually 100% secure and it's not suitable for certain tasks.
0:08:38 > 0:08:40So if it appeals, just make sure you're aware
0:08:40 > 0:08:43of its limitations as well as what it's capable of.
0:08:43 > 0:08:46OK, next up, a look at this week's Tech News.
0:08:47 > 0:08:51Police in Japan have arrested a man suspected of possessing guns
0:08:51 > 0:08:53made with a 3-D printer.
0:08:53 > 0:08:5627-year-old Yoshitomo Imura is believed to have kept
0:08:56 > 0:08:58the plastic guns at his home in Kawasaki.
0:08:58 > 0:09:01It's the first time firearms laws have been applied
0:09:01 > 0:09:05to 3-D printed guns, which can be lethal.
0:09:05 > 0:09:08easyJet is turning to drones to inspect its aircraft, saying
0:09:08 > 0:09:12it may introduce flying maintenance robots as early as next year.
0:09:12 > 0:09:14The drones, developed by the Bristol Robotics Centre,
0:09:14 > 0:09:17will be fitted with lasers and video cameras to scan
0:09:17 > 0:09:20the outside of the aircraft and report back to engineers.
0:09:21 > 0:09:22Forget gaming.
0:09:22 > 0:09:25The Norwegian army has found a slightly different use for the
0:09:25 > 0:09:29virtual reality headset Oculus Rift - driving a tank.
0:09:29 > 0:09:33Cameras on the armour show a 360 degree feed of the terrain,
0:09:33 > 0:09:35which helps soldiers to steer the vehicle.
0:09:35 > 0:09:39Testing is ongoing as army officials admit the picture quality
0:09:39 > 0:09:43isn't yet good enough to tell if the enemies are carrying weapons.
0:09:43 > 0:09:46And a new range of kitchen appliances that can be
0:09:46 > 0:09:50controlled by text message has gone on sale in South Korea.
0:09:50 > 0:09:54The LG models allow users to request a picture of the inside of their
0:09:54 > 0:09:58fridge be sent to their mobile phone so they can see what they've got.
0:09:58 > 0:10:01You can also ask this washing machine what it's up to to
0:10:01 > 0:10:04save getting into a spin over the laundry.
0:10:04 > 0:10:05Hm.
0:10:08 > 0:10:12Now, we all like to take pictures of what we're up to with friends, but
0:10:12 > 0:10:16have you ever wondered what makes a great photo, a popular picture?
0:10:16 > 0:10:18And here's a thought.
0:10:18 > 0:10:22If you did know that, would it change the pictures that you took?
0:10:25 > 0:10:27At the Massachusetts Institute of Technology,
0:10:27 > 0:10:31one researcher reckons he can predict which photos will be
0:10:31 > 0:10:35the most popular after analysing more than two million snaps
0:10:35 > 0:10:37posted to Flickr.
0:10:37 > 0:10:40His algorithm analyses colour and recognises objects.
0:10:41 > 0:10:44So, what's he learned?
0:10:44 > 0:10:47Miniskirts tend to make photos popular, bikinis and such,
0:10:47 > 0:10:50as well as, I guess, revolvers.
0:10:50 > 0:10:53And the ones that, you know, tend to reduce the popularity
0:10:53 > 0:10:59of photos are things such as laptops, spatulas and plungers, as well as...
0:10:59 > 0:11:01You know, some of the colours also tend to affect
0:11:01 > 0:11:04the popularity of photos, such as, you know,
0:11:04 > 0:11:08having brighter colours tends to make people click on them more
0:11:08 > 0:11:13often as compared to having, like, the dull or more outdoorsy colours.
0:11:13 > 0:11:16Actually, Aditya's colour analysis shows that these are the most
0:11:16 > 0:11:18likeable tones.
0:11:18 > 0:11:21So aim to include the ones on the right in your pictures.
0:11:21 > 0:11:24What do you hope will come of this study?
0:11:24 > 0:11:27Do you hope that we'll all become better photographers or do
0:11:27 > 0:11:30you just think that we'll all start putting more swimsuits
0:11:30 > 0:11:34and fewer plungers in our photos to get more likes?
0:11:34 > 0:11:37Part of the problem that I was hoping to help people solve was,
0:11:37 > 0:11:39I call this a problem of selfie selection.
0:11:39 > 0:11:41I guess people tend to take, you know, I don't know,
0:11:41 > 0:11:4750 or 100 photos and possibly select one or two out of them to upload.
0:11:47 > 0:11:50And maybe, if you have this objective way to figure out which one is
0:11:50 > 0:11:54likely to be more popular, it might save you some time
0:11:54 > 0:11:56and maybe you can do something else.
0:11:56 > 0:12:00You know, it's hard for me to say exactly how people could use this,
0:12:00 > 0:12:04but I think there's many more...
0:12:04 > 0:12:07There's a lot of space left to explore here.
0:12:07 > 0:12:11But is there a danger that if we all start taking these good photos,
0:12:11 > 0:12:13good photos will become boring?
0:12:13 > 0:12:17I mean, I don't know about you but if all my Facebook feed was,
0:12:17 > 0:12:20you know, full of women wearing swimsuits,
0:12:20 > 0:12:23I'd probably be spending all my time there.
0:12:23 > 0:12:25Well, armed with the knowledge of what sells,
0:12:25 > 0:12:28we aimed to take the most popular picture ever!
0:12:31 > 0:12:33- HE CLEARS THROAT - Well, look.
0:12:33 > 0:12:36It's got a revolver - a toy one - a mug from the BBC canteen
0:12:36 > 0:12:39and a swimsuit. So...
0:12:39 > 0:12:44Well, the results were slightly disappointing, to be honest.
0:12:44 > 0:12:45Do you think we missed something?
0:12:45 > 0:12:51Is it the woman with a lot of skin on show or is it the bikini
0:12:51 > 0:12:54that makes it a popular photo? Be honest.
0:12:54 > 0:12:58I'm almost certain it's the bikini itself. No.
0:12:58 > 0:12:59I'm just messing with you.
0:12:59 > 0:13:02It's actually the person wearing the bikini.
0:13:03 > 0:13:06OK, joking aside, it does seem that we're starting to discover
0:13:06 > 0:13:09more about what makes a photo popular.
0:13:09 > 0:13:13So let's add another dimension to the mix - time.
0:13:13 > 0:13:17What if your photo was shared as soon as you took it, together
0:13:17 > 0:13:22with your exact location, pinpointed and broadcast for everyone to see?
0:13:26 > 0:13:30This is what's happening in Stockholm right now.
0:13:31 > 0:13:35Instant Peeping is a Stockholm-based website that displays live
0:13:35 > 0:13:38Instagram posts on city maps around the world.
0:13:39 > 0:13:44Dubbed a real-time social media experiment by its creators,
0:13:44 > 0:13:46users - or peepers -
0:13:46 > 0:13:50can watch the pics pop up as they're taken in any of nine cities.
0:13:50 > 0:13:55The reaction from people so far has been positive overall and,
0:13:55 > 0:14:00depending on where they're from when looking at different countries,
0:14:00 > 0:14:03some countries have been talking more about the voyeuristic
0:14:03 > 0:14:08part of it and calling it, like, the big brother of Instagram,
0:14:08 > 0:14:12and some other people are really interested in the technology
0:14:12 > 0:14:14part of it, how it works.
0:14:14 > 0:14:18Instagram stores a lot of data alongside each picture -
0:14:18 > 0:14:21its location, timestamps, filters used and so on.
0:14:21 > 0:14:24And that means that Instant Peeping can plug the location data
0:14:24 > 0:14:29into Google Maps and precisely pinpoint each snap.
0:14:29 > 0:14:32And unless you revoke Instagram's access to your location,
0:14:32 > 0:14:35this information could be aggregated by any site which want wants
0:14:35 > 0:14:37to make use of it.
0:14:37 > 0:14:41It's an interesting question - who actually owns the data?
0:14:41 > 0:14:46It depends on how you interpret the policies, I suppose.
0:14:46 > 0:14:50Instagram or Google haven't contacted us yet.
0:14:51 > 0:14:53Wherever you look, though,
0:14:53 > 0:14:57it does seem that you're likely to come across some familiar faces.
0:14:57 > 0:15:01The most popular images right now, I would say, are selfies
0:15:01 > 0:15:04and also cats.
0:15:04 > 0:15:08Cats are a constant and selfies seem to be trending now.
0:15:10 > 0:15:16It started as an ambitious IBM research project in 2007 -
0:15:16 > 0:15:19to build a supercomputer which was capable of understanding
0:15:19 > 0:15:23questions and answering them quickly and accurately.
0:15:23 > 0:15:25Seven years on, Watson, as it became known,
0:15:25 > 0:15:30is moving with the times in that it's shrinking and going mobile.
0:15:30 > 0:15:32In fact, apps that use Watson will be
0:15:32 > 0:15:35available for your smartphone later this year.
0:15:35 > 0:15:39IBM has challenged companies to come up with clever ways of
0:15:39 > 0:15:42taking advantage of all that supercomputing heavyweight
0:15:42 > 0:15:45and Simmi Das has been to see one of them.
0:15:53 > 0:15:54Meet Nate.
0:15:54 > 0:15:58Nate sells outdoor gear at the North Face store in San Francisco.
0:15:59 > 0:16:05Now meet Watson, IBM's cognitive computing whizz.
0:16:05 > 0:16:08Three years ago, the supercomputer won the top prize
0:16:08 > 0:16:12on the popular American TV quiz show Jeopardy.
0:16:12 > 0:16:15Ask Watson a question in plain English
0:16:15 > 0:16:20and it uses sophisticated tech to speedily find the best answer.
0:16:20 > 0:16:21And we find...
0:16:24 > 0:16:27Not just a literature buff, Watson assists physicians with
0:16:27 > 0:16:31an immense job - keeping current on clinical trials.
0:16:32 > 0:16:34And soon, it'll help shoppers.
0:16:35 > 0:16:42San Francisco start-up Fluid is using it to power its expert personal shopper or XPS app.
0:16:42 > 0:16:44It's building a prototype for the North Face.
0:16:45 > 0:16:50Watson's computational might is the result of several technologies,
0:16:50 > 0:16:54including artificial intelligence and machine learning.
0:16:54 > 0:16:57What Watson can do and its power is that it can ingest millions
0:16:57 > 0:16:58and millions of documents.
0:16:58 > 0:17:01What's called unstructured data, which is essentially anything that's
0:17:01 > 0:17:05written or spoken, it can digest, consume and learn from that content.
0:17:05 > 0:17:09As you ask it questions, it gets smarter and smarter.
0:17:09 > 0:17:12Content fed to Watson creates a corpus -
0:17:12 > 0:17:14a database stored in The Cloud.
0:17:14 > 0:17:18For the XPS app, it could include product catalogues and reviews.
0:17:18 > 0:17:20Think of it as Watson's cheat sheet.
0:17:21 > 0:17:24Can you tell me more about ABS technology?
0:17:26 > 0:17:31Watson also relies heavily on natural language processing or NLP.
0:17:32 > 0:17:35But that could create confusion.
0:17:35 > 0:17:38What happens when you're communicating in human language
0:17:38 > 0:17:41is you have expectations that the system on the other end
0:17:41 > 0:17:42is going to act like a human.
0:17:42 > 0:17:45So if it misunderstands something in a way a human wouldn't,
0:17:45 > 0:17:48it's frustrating, or worse, you get the wrong outcome.
0:17:48 > 0:17:51To use XPS, just ask a question.
0:17:53 > 0:17:56What technical pack is needed for an expedition to
0:17:56 > 0:17:59Fitz Roy, Patagonia, in the winter?
0:18:01 > 0:18:06XPS aims to offer the expertise of a star salesperson with some added convenience.
0:18:07 > 0:18:10Ever been shopping on a particularly busy day,
0:18:10 > 0:18:14maybe mother's or fathers' day, or worse, Christmas Eve?
0:18:14 > 0:18:17A salesperson might be hard to find, but an app?
0:18:17 > 0:18:19That you can just pull out of your bag.
0:18:19 > 0:18:22So you can type your questions in, you can actually speak to it
0:18:22 > 0:18:25and it will ask you questions back and it will give you products
0:18:25 > 0:18:28recommended along the way based on what you're talking about.
0:18:28 > 0:18:30And that's just the start.
0:18:30 > 0:18:33IBM is using Watson to tackle problems in Africa,
0:18:33 > 0:18:36like water sanitation and education.
0:18:36 > 0:18:38It's a tall order, one that'll test
0:18:38 > 0:18:42whether Watson lives up to its supercomputer status.
0:18:44 > 0:18:48Simmi Das with a massive brain in a tiny phone.
0:18:48 > 0:18:51Now, even if you're not using these as a full-on supercomputer,
0:18:51 > 0:18:53they are, of course, really useful.
0:18:53 > 0:18:57For example, they help us find stuff - bargains, businesses,
0:18:57 > 0:19:03buildings, people. But what happens if you don't want to be found?
0:19:03 > 0:19:08Well, Kate Russell has an app now that helps you avoid your friends.
0:19:08 > 0:19:09Here comes Webscape.
0:19:13 > 0:19:15The prolific use of social media
0:19:15 > 0:19:18and an apparent compulsion to friend everyone
0:19:18 > 0:19:24we meet has resulted in connections with hundreds of random people,
0:19:24 > 0:19:27not all of whom you want to stop and chat with.
0:19:27 > 0:19:30Cloak is an iPhone app that hooks into social networks
0:19:30 > 0:19:36Foursquare, Instagram, Twitter and Facebook, keeping track of where your
0:19:36 > 0:19:40so-called friends last checked in so you can avoid them if you want to.
0:19:44 > 0:19:48It calls itself the antisocial network tool,
0:19:48 > 0:19:52allowing you to flag certain people so you'll be alerted
0:19:52 > 0:19:55if they pop up close to where you are.
0:19:55 > 0:19:58If you're in a particularly unsociable mood,
0:19:58 > 0:20:00or you're up to something you'd rather keep private, you can
0:20:00 > 0:20:03set it up to alert you for everyone.
0:20:04 > 0:20:08Of course, this app does rely on your contacts checking in somewhere
0:20:08 > 0:20:12with Foursquare or posting a location-tagged image
0:20:12 > 0:20:14through Instagram, for instance.
0:20:14 > 0:20:18But those are just the kinds of people I like to avoid,
0:20:18 > 0:20:20so it works perfectly for me in that context.
0:20:25 > 0:20:29If you've ever felt frustrated about the lack of transparency some
0:20:29 > 0:20:33social platforms have when it comes to privacy, My Face Privacy is
0:20:33 > 0:20:39a free download that takes away the pain by managing everything for you.
0:20:39 > 0:20:42It works with Facebook, Twitter, LinkedIn and Google+,
0:20:42 > 0:20:45and using the plain language interface, you can
0:20:45 > 0:20:49set close friends and choose what you want to share with who.
0:20:49 > 0:20:53The software then updates your settings automatically without
0:20:53 > 0:20:54you needing to hunt through menus
0:20:54 > 0:20:58and dig deep into the complicated interface on each site.
0:21:04 > 0:21:07Even if you think you've got a handle on the privacy settings,
0:21:07 > 0:21:10software developers are constantly changing
0:21:10 > 0:21:13and tweaking stuff behind-the-scenes
0:21:13 > 0:21:16and My Face Privacy will keep an eye on that for you
0:21:16 > 0:21:19and automatically make any amendments necessary
0:21:19 > 0:21:23if a change affects the information you're sharing.
0:21:23 > 0:21:26Once you've set your own privacy settings, you can
0:21:26 > 0:21:30add additional accounts to organise your children's networks, too.
0:21:30 > 0:21:33It's a great way to make sure the whole family are safe.
0:21:38 > 0:21:42The London Underground has been running for 150 years
0:21:42 > 0:21:45and carries over a billion passengers each year.
0:21:45 > 0:21:48Running it is a complex city planning job
0:21:48 > 0:21:52and you can find out exactly how complex by playing Mini Metro.
0:21:55 > 0:21:58This is a bit like SimCity, where you have to make
0:21:58 > 0:22:01decisions about what resources to use where,
0:22:01 > 0:22:06setting up new lines to link the stations as they're built.
0:22:06 > 0:22:09And choose carefully because if your stations get overcrowded
0:22:09 > 0:22:13and your passengers can't get where they need to go,
0:22:13 > 0:22:16the game is over and you'll have to start from scratch.
0:22:16 > 0:22:19The early alpha build of the game is free to play online
0:22:19 > 0:22:22or as a Mac, Linux and Windows download,
0:22:22 > 0:22:26with the full version of the game, a premium upgrade, coming soon.
0:22:31 > 0:22:35The privacy bandwagon rolls on and this week, colourful antivirus
0:22:35 > 0:22:39software pioneer John McAfee has launched a messaging app.
0:22:39 > 0:22:43Chadder is free on Android and Windows phone 8.1
0:22:43 > 0:22:46and focuses on encryption and security.
0:22:50 > 0:22:53For iPhone users, a new way to share -
0:22:53 > 0:22:55Route Share lets you share your location
0:22:55 > 0:22:58and when you should arrive at your destination, with real-time
0:22:58 > 0:23:03updates via SMS, e-mail and other popular social platforms.
0:23:03 > 0:23:07Perfect for making sure whoever is expecting you has got the kettle on.
0:23:12 > 0:23:13Thank you, Kate.
0:23:13 > 0:23:18Kate's links are available at our website if you missed them.
0:23:18 > 0:23:22You'll also find clips from this week's programme and previous progs there, too.
0:23:22 > 0:23:24And if you'd like to get in touch with us,
0:23:24 > 0:23:27please use Google+, Facebook or Twitter or something called
0:23:27 > 0:23:30e-mail, which, I'm led to believe, is going to be big one day.
