is time for Click. It's your birthday, it's your birthday, it's


your birthday. That's all the BBC budget could stretch to. This week,


as the World Wide Web reaches a special milestone, Click looks at


its future and asks whether it is finally reaching maturity. Mobile


phones and cancer. We look at the latest research to find out if


children in particular are at risk. And the latest Tech News from


around the globe. And if you find this annoying, we have a handy way


to connect this to this. Welcome to n


important anniversary in the history of the World Wide Web. It


was originally conceived in 1989 but it was not until two years


later that it was launched to the rest of the world. In August of


1991, 20 years ago, British scientist Sir Tim Berners-Lee


sealed his place in history when he posted a summary of his big idea on


the internet. It didn't look like much but this summary was about to


make the internet a whole lot easier to get around. In the 1960s,


the internet was reserved for military and academia. It was


thought it was difficult to use and not much fun. Tim Berners-Lee


decided what the world needed was an easier way to navigate all the


data that were stored online. And a quick way to jump from one document


to another. The World Wide Web was born to a very modest start.


fact that a hotchpotch of people came up with this is one of the


main amazing things. A number of people played different parts.


Web has grown since then to billions and now hundreds of


billions of pages, where people meet, businesses trade, revolutions


rise, knowledge grows and animals do the funniest things. But over


the years, Tim, now Sir Tim, has high hopes that as the information


continues to grow, the scale of solutions will occasionally help us


make giant leaps forward. The thing explodes when somebody looks at a


piece of data and realises it connects with something else. It


could lead to the curing of disease or figuring out why this has


something to do with Alzheimer's or cancer. Or realise something about


global warming because we managed to get all the data about the state


of the world out there. continues to nurture his baby which


is no longer an infant and has arguably now come through its


adolescent years too. He is as excited as anyone about where it


goes from here. I have learnt the most exciting thing about this


technology is that people do with it things you could never imagine.


This week we will look at the next 20 years of the Web. Thinking about


what it might look like. With me is the Deputy Editor of Computer


Active. Welcome. And a professor who has a CV so long we do not have


time for it. He advises the government on all things web. In


fact, you are doing that today. Welcome. Starting with the big


question, what do you think the biggest change to the Web will be


in 20 years? It has got to be languages. The first ten years of


the Web, it was a medium mainly involving English and using the


Roman alphabet. Over the last few years we have seen a huge growth of


users from people who don't speak English. A move to allow Web


addresses to be written in other alphabets. Billions can get on the


internet through general support for their language. The other thing


is mobility. So they will get internet on smartphones or through


all sorts of services delivered on a range of devices, not necessarily


your standard laptop or desktop. are hearing now of the rise of the


app, on smartphones and personal computers. They do not technically


use the internet, they access the information on the internet in a


different way. Will that be the future? Do you think the Web has


had its day? I do not think the two are separate. Some apps, on their


own, have no connection to the internet. Most of the really


important apps are incredibly reliant on the internet for their


data. But they have only come along in the last two years and there is


a lot of evolution to go on in the next ten years. Back in 2003,


scientists said we have to keep open to the Web so anybody can


innovate. Is there a danger big companies are trying to lock down


parts of the internet for their own services in order to make money and


shut their competitors out? There are issues with monopolies but the


fact that in order to start up most companies or businesses, you might


take a couple of weeks or months of preparation to build machinery and


hire people. To start on the Web, you can start immediately and make


a product in an hour. That kind of innovation is always a threat to


the big companies. It may feel like Google is the only game in town


here but there are 6 billion pages of Mandarin they have not indexed.


Google is not the search engine of choice in China. And the Twitter


equivalent in China that put on 14 million users in two months. There


is a lot of space for people to enter the market. What we have with


the Web is the potential to get anywhere at any time at a price


that is marginal. There are the occasional reports you see that


suggests the Web is changing the way we think. It is affecting how


bothered we are to remember things because you can just go online to


check the facts. Is the Web changing the way our brains work or


the way we go about our thinking? Technology has always changed us,


ever since we developed the first tools. So you can argue the brain


has been changed and shaped by the tools available to us. This is not


new. Literacy did the same thing. Offloading certain search tasks is


exactly what we will do. But do we have the skills and ability to


review, create and generate stuff, that is the measure of human


intelligence. Thank you for your time. Next, this week's Tech News.


One security firm says it has uncovered the most sustained and


widespread series of hacking attacks on a single source ever. In


the report, it says more than 72 institutions, including the UN,


defence firms and the International Olympic Committee, were


systematically attacked over five years. There is speculation the


Chinese government is behind the attacks. But it isn't known who's


responsible and the Chinese government refuses to accept any


responsibility. It is now OK to mash-up music and videos without


asking for permission. If you are in the UK, that is. It is part of


the British government's relaxation of copyright laws. Copywriting


media for personal use or 'format shifting' is no longer against the


law. Even though most of us have been doing it for ages. And the


makers of the BlackBerry have launched a new line of smartphones.


The first is the updated operating system, BlackBerry 7. It includes


the all touch-screen Torch. The company's first touch screen phone.


It's been updated with mobile payments and a digital compass. The


popular BlackBerry Messenger is being integrated into some apps,


meaning people will not have to leave the application to chat. A


couple of weeks ago we talked about podcasting and we asked you what


you thought made a good podcast. We got a lot of emails and tweets like


this one. This person thinks his podcast is the best. Then we had


more insightful feedback as well. Like this one. It says, what makes


a good podcast is the same as a good radio station. Content first,


then a presenter who is worth listening to. In fact, we have had


so much feedback that we invited LJ Rich to come back to give us


another sound bite, this time to share some industry secrets on ways


to improve the output. Making your broadcast sound better does not


have to cost any money. Like programmes, they benefit from some


structuring. A few short items with presenters in between. Keep your


listeners interested by propping up the show with other voices. We keep


it tightly formatted, so we have eight minutes on air and then we


edit it down. If your voice over is recorded in the studio, it can have


little echo. Like this. A few different acoustic backgrounds can


also add interest. But do not be afraid to get out and about.


Natural sound sets the scenery. Once you have sorted your content,


there are free programmes on the internet that can give you extra


control of the sound. For example, Audacity is free sound editing


software that lets you stick your sound together. Professional radio


programmes tend to have a constant sound level. There are no overly


loud bits that make listeners keep messing with their audio control.


Free programs can normalise your files for you. Although lots of


sites will help you upload and host a podcast, the quick way to get


your audience is to upload pre- recorded files and let listeners


access them through iTunes or by clicking on the RSS link. With


radio broadcasting, you have an on- air audience that can listen to you


as it goes out and there is an audience that will download it


later. That changes the way you think about radio. Some people may


download your podcast after its release date. That does not mean


you have to ditch time-sensitive content, just add a bit of


background information or context. Be consistent and get your audience


used to when they can expect the next episode. These tips are on our


website. Follow them and you never know, you may make it to the top of


Given that we are using these more and more every year and usually


close to our heads, it is understandable that mobile phones


have been the focus of health concerns ever since we started


using them. But now two decades on, what is the truth? Are they a


health risk and should we be thinking twice about letting our


children use them at such an early age?


The International Agency for Research on Cancer has reclassified


mobile phones recently. The UN agency has fallen short of saying


mobile phones are definitely hazardous. Instead they have re-


classified mobile phones as possibly carcinogenic. The


reclassification was the result of a meeting held here at the


headquarters in Lyon of the world's leading scientists. They reviewed


experimental data on animal research but also the longest


running research project into the use of mobile phones by brain


cancer sufferers. The strongest evidence came from the evidence of


cancer in humans. There was evidence that there may be an


association between the use of mobile phones and certain types of


brain cancer. The body representing the interests of the mobile


industry followed up the findings, saying that the classification


suggested that a hazard is possible but not likely. While they


acknowledge that some mobile phone users may be concerned, they said


that present safety standards remain valid and there was need for


further research. Research into health and mobile phones has been


beset with difficulties. We have been using them for a relatively


short time. Cancers can take decades to develop. It is an area


replete with debate. Most scientists seem to agree about one


thing. If mobile phones are hazardous, children may be more


vulnerable than the rest of us to their possible ill-effects. If the


penetration of the electromagnetic waves goes four centimetres into


the brain, four centimetres in an adult brain is just the temporal


lobe. Not many important functions there. In a child, the more central


brain structures are going to be exposed. In addition, kids have a


skull which is thinner and less protected. There are many reasons


that make them absorb more radiation.


European research just published in America's Journal of the National


Cancer Institute has concluded children who use mobile phones are


at no greater risk of developing brain cancer than those who don't.


Critics say the research is too short-term and the data it used out


of date. Certainly for parents giving their children mobile phones


helps to keep tabs on them when they are out and about in a world


full of hazards. But if the hazard is the mobile phone itself, we


would be well advised to take precautions. Text, hands-free, use


a landline, the sort of advice that many would like to see passed on to


customers. After 20 or so years with mobile


phones, some experts say there is nothing to worry about. The UN said


there might be a problem. Others believe there is definitely an


issue. It is up to us whether to decide to dismiss the warnings or


to take minor precautions to make sure those most vulnerable do not


blame us if the most dire predictions turn out to be correct.


Another thing about modern smartphones is that many of them do


not have physical buttons. When you are typing e-mails or texts you


have to use the on-screen keyboards with the tiny keys. I don't know


about you but sometimes I miss having a full-size physical


keyboard. Kate Russell has a solution to my fat fingers.


If you are all fingers and thumbs when it comes to touch screen


keyboards, Android owners can find some relief when connected to a


desktop machine through wi-fi. The wi-fi keyboard application is free


to download unless you change your input method to hook up with your


computer's keyboard. Then you can input text through your browser.


You can also connect to your computer using a USB cable. This


works best in terms of latency. It takes a little more technical know-


how to set up. Launch the application icon for full


instructions. It is worth noting that any text you input through


your browser could potentially be recorded, so don't do your internet


banking. If you have a lot of text to reply to, I can see this saving


a lot of frustration and random auto corrects.


You, dear viewer, are such an interesting person with so many


fascinating friends. You should have a museum dedicated to you. Now


you can at Intel. By linking your Facebook account the account


creates a visualisation of all the texts, videos, images and connects


them. This three-minute sequence is built using a snapshot of the media


that is connected to your account. All accompanied by piano music. My


favourite is the end room where you see pictures of your friends and


family being sorted by robotic arms. When you are complete you can share


the exhibition on your wall with a series of stills. It is a shame you


cannot share the whole animation sequence.


If you have trouble understanding the drivel posted on Twitter, this


next site will not help you. It might make you laugh. The URL is a


little complicated. And yes, dot, that can be dot...slash.. Don't


worry, it is on the website. You just enteryour Twitter handle and


the application will draw a random selection of its words and phrases


that you have used to suggest what your next tweet might be. I found


it more fun putting in the user names of some of Twitter's biggest


personalities, comedians, and some of the more outspoken celebrities.


It is a fascinating and random glimpse inside their minds. The


results can be surreal to say the least. But entertaining enough to


pass a few minutes at lunchtime. With the school holidays in full


swing the children are running around everywhere, fighting over


the best toys, waggling their tails. I am of course talking about the


kind with four legs. You can watch them to your heart's content on the


Mead Open farm GoatCam. The Webcam shows their seven nanny goats and


two kids rambling about enjoying their first summer. Tune in quick


because the camera only feeds live until the beginning of September.


Don't you hate it when you have got an itch you cannot scratch?


If you have any suggestions for a future Webscape get in touch. You


can e-mail us or tweet us. Those are the contact details if you have


any ideas about the future of the web. Don't forget, everything from


the programme is on the website. That includes a link to Click on


the radio. The Web is not the only technology


celebrating an anniversary this week. The click radio team is


celebrating the 30th birthday of MS dos. That's it. Thank you For


A week ago, we were suffering for with an uncomfortably warm night.


But at the moment it is much pressure. It is going to be a cool


day. Temperatures are rather disappointing for August and


feeling even fresher because of the strength of the wind. It is kind to


be wet in places as well. Bands of Shari rain also tracking their way


southwards. Before they arrive, parts of north-east England and the


Midlands will hate this might well have some sunshine. Blue skies for


East England it -- a East Anglia and the south-east. Sunny spells


for much of the south coast of England. Shell was not too far away


from the south-west. Some of them get blown through here on a fairly


brisk wind. Also most of Wales. Much of the south-east of Wales and


the West Midlands will start with some more cloudy in north Wales and


a cloudy start in Northern Ireland. The breeze is going to make it feel


particularly miserable on the Moray coastline. Temperatures struggling


through the day. The wind is making it feel really quite chilly. Some


sunny spells in south-west Scotland. It will disappear from southern


areas as the cloud develops more widely. Some places will stay dry.


But nowhere is going to be particularly one. Temperatures at


very best, 20 Celsius. The rain does peter out, it makes it through


the evening, but one of two are scattered showers, most of us will


have a dry night. It will bring cooler air. It will -- it will be a


chilly night again. Temperatures down to single digits. Tuesday


looks like being a largely dry day. The area of high pressure keeping


things settled. A weather front will arrive on Wednesday. On


Tuesday, most of us will be dry. Temperatures nothing spectacular.
