officers. Now it is time for Click. Mobile phones can be tracked. The

internet can be monitored. So why can't be predicted a riot? -- Why

Can't We predict a right? We will look at the technology behind this

week's riots. Just how much blame can we place on BlackBerry, Twitter

or Facebook. We take you on a journey into sound. All the latest

tech news and webscape. Over the last week, England has seen the

worst riots in living memory. What started as a protest at a police

shooting of a young man in London quickly escalated into several

nights of chaos. Shops were ransacked, police were attacked and

buildings burned. Unlike previous disturbances and demonstrations

this was not just one large mass of people moving through a city. Mops

appeared to spring from the way before disappearing again only for

a different group to so bring up someone else. How did they know a

way to meet and why did the police knocked me that? This is not the

first time that mobile phones and social networks have been used to

organise large crowds. We explained how Facebook had been used to build

a groundswell of support for uprisings in North Africa and the

Middle East and how Twitter had been used to disseminate

instructions to protesters in London after they had begun. Any

one, including the police, can monitor the chapter, as long as

they are looking in the right place. This time the rioters used a more

private way to get in message out, one which a boy did the days of the

authorities. -- avoided the view of the authorities. BlackBerry is the

most popular phone among young people in the UK. That is partly

down to the BlackBerry Messenger service. Only those invited to the

group can read them. That makes it difficult for police to see what is

being organised and spot clues as to where trouble might happen next.

Messages are encrypted before they leave the handset and the data is

transmitted to BlackBerry service in Canada before being sent on to

the recipient devices over the mobile phone networks. One of the

ways that have been communicating is by a BlackBerry Messenger

because it cannot be traced and is difficult for the police to track.

If it is technically possible I would like to see BlackBerry

Messenger disabled from 6pm at night to 6am in the morning to stop

the people co-ordinating these things from organising in the way

they have been. In the UK we have something called the Regulation of

investigatory Powers Act, Regulation of Investigatory Powers

Act, which allows police to monitor communications in some

circumstances. It is not a licence to sit through everyone's

Communications. -- sift through. The maker of BlackBerry, RIM said:.

We complied with the Regulation of investigatory Powers Act and co-

operate fully with police forces. They will already want to know his

records they want to see. -- whose records. In right situation, on

dark nights with covered faces, surely it should be possible to use

technology to trace those involved. One lawyer, a former advisor to the

government on covert policing, says it is far more difficult than you

might think. They are no doubt it responsible commercial entity that

will want to with this the police. It is questionable inveigled hands

whether they can offer that. It may be a breach of the Data Protection

Act. The Mutual Assistance Agreement is engaged and it becomes

more bureaucratic, time consuming and problematic. In the next few

weeks we will find out it ANA chronic evidence helps the police

to track down those responsible for scenes like these. -- electronic

evidence. The government has promised to look into whether it

would be right to stop people communicating by social media if

they know it there are putting social disruption. This is not

simply a demonstration of how social media can wreak havoc. As

events quickly unfolded local forums and services like Twitter

helped to keep some Londoners aware of rioting in their area. One

social media experts used his skills to post an inner piloting

the trouble spots. I started to put some of the riots on a Google Maps

and work out what they were. Quickly it became apparent the were

riots in different parts of London. So will I thought that we needed to

add this to work out that people could share with other people and

work out what was actually a right and what was a remark. Discounting

and sit in fact from online fiction almost requires the skills they did

it will detected. Some people were reporting that tanks were coming

into London. That was a message about tanks in Egypt from four

months ago. The difficulty is that you do not know whether something

is true or false. I was involved in making sure that established news

organisations were reporting on the same thing. I checked local

newspapers and saw what people wrote in their own blocks. And

seeing whether lots of different people were talking about the same

thing in different ways. The police have also turned to

social media hoping to identify rioters and looters. They posted

CCTV images on their website and Flickr. In a matter of a was the

Riot Clean Up bit her at her amassed $30,000. -- tweeter. A lot

of kids were not local. Twitter has brought more people here this

morning and writers last night. A thing that sends a very powerful

message. With me is the editor up of a take block, Mike Butcher.

Should we be blaming the technology you? You can use it to make good

phone calls or bad for an calls. It is a power using the technology to

amplify an existing situation. At the same time social media and the

BlackBerry can be used to bring the community together. How realistic

is it that BlackBerry Messenger could be shut down at particular

flashpoints like riots or protests Kris -- --? Obviously it is cutting

off a said this. But in extreme circumstances like terrorist

attacks the mobile phone network you shut down for various reasons.

The BlackBerry Messenger service is run by Research In Motion. The

BlackBerry network would take those SIM parts of the network. -- SIM

hearts. People could switch to other replications. They do not

necessarily only carried one handset. It is not just about

taking one type of service up the network. People will find other

means. I am sure you will have views on this but please get in

touch with us. The latest Tablet launch has not

gone to plan. A German court has granted Apple an injunction

except for the Netherlands. -- Alexei have. They said they would

act immediately to defend their intellectual property rights.

Facebook has launched its own Messenger this week. It works

across different platforms to both iPhone and Android phones. Uses

will also be able to send SMS messages to mobiles. It comes among

the head of Apple's release which also includes an integrated

messenger. 22 fate apple stores have been discovered in China.

Earlier this month we discovered five baked apple shops in the same

city. The retail watchdog has said that a hot line for people to

report them. We all none at least one of them.

You may very well be one of them. I am talking about audio files,

people who spend a disproportionate amount of time and money in the

pursuit of sound perfection. Have you wondered whether these people

are wasting their money? There are small things anyone can do to

improve the quality of their sound system without blowing get that

balance. We have been looking at the evolution of home audio. The

breathtaking sounds of a live orchestra. Everyone is aiming for

one thing. The hairs on the back of unit. A bunch of musicians in your

living room may be impractical, but that is the idea when you listen to

a recording of the BBC Philharmonic. And her wit his record it is the

first state of high quality sound reproduction. The equipment is

formidable. The thing in the middle records the whole orchestra. Other

microphones report each individual instrument in case it needs a boost.

We have a sound maestro who has the best years in the business. All the

microphones are patched into imports in the floor. They are

converted into digital signals. The whole thing is digitised and then

we arrived at the centre of the studio, which is these sound desk.

When setting up your system, if the speakers are not pointing to your

ears, you name is the top notes. The speakers are designed for the

person sitting at the desk. Even at the back of the control room miss a

lot of those high frequencies. I asked them to come over here and it

These days there are many soundbox. But there is a special kind of

audiophile bat spends above and beyond most of us. Welcome to high-

end audio. You are looking at around �10,000 worth of speakers

being made. High Speed Two coats each ranging different speaker

frequencies. there are projections of how loudspeakers may behave

before even building them. That is his and a colleague or echoless

chamber - -- chamber. He still has to spend a lot of time testing

prototypes. The more we can spend on it, materials and construction

and research and development, the closer we can get the idea of this

perfect Speaker with a beautifully flat frequency response, without

any Cabinet coloration. He is trying to get better stereo imaging.

But the biggest obstacle is space which this acoustic professor is

all too aware of. You do not get the true sound of the orchestra

because the living room you have to put the sound through is nothing

like a concert hall and you cannot take that out of the equation. It

will bounce off the walls and you will hear the effects and

reflections. So you have an augmentation of the sound that

would never happen in a real concert hall. So it always sounds

different are the real space. You can get rid of those imperfections

by putting in the could mean. Or perhaps scatter the sound. So put

things that would make the sound bounced off in different directions.

That can be specialist material or things like bookcases. That makes

the groom appeared eager. Because your living room is too small and

the reflections arrive early. If they arrive early, you can get them

to bat in different directions are we to Piers bigger. There is more

take on the way. These people think it is worth going back in time to

search for the sound of the future. One idea that has been around since

the 70s is a wave field synthesis system. A circle of a one UN -- of

a number of deer hide speakers that creates a surround-sound blanket.

In this case, it is a cafe. Listeners inside feel they can

point directly at a source. It laughs in the face of me a stereo.

Stereo at home is very simply... It relies on the feeling that

something is moving in the sound field. Stereo also depends on this

idea of experience in the sound desk between the speakers. We have

a large sound -- large space where people can experience that feeling.

Currently, this system could set you back about �200,000. But this

kid only cost one-tenth of that and is running on a household PC. This

step closer to home. But assuming you do not have time or space for

128 because, how about just 14? Another all be but goody has been

given a modern twist. With six speakers at the height, and four on

the ceiling and four on the floor, sound can be placed anywhere. This

demonstration used as a connect Controller to help you move it

around. We are looking at have been 5.1 surround-sound. In the future

you might want three-dimensional sound. So we are looking at the

only a new level of experience into the mix. In this set-up, the

computer works out how to direct the sound once you tell it where

the speakers are. This is still some years from mass-production.

But the sound processing programmes can be down that -- downloaded. It

can be used with only one speaker as well. It is a great example of

how the quest for perfect sound reproduction always comes back to

individual preference. Of course, everybody hears the world Evenley

but one thing experts agree on is how to buy a ticket. Try it and if

you like it, buy it. Just do not get our reporter

started on commerce. It will be there all day.

Here on Click, we are always receding links. You suggest them on

e-mail or post them online. The problem is, we never know were

there a link is safe to click on. If it comes from an unknown source,

the best thing to do is pass it on to Kate Russell who can take it out

for you. A good rule of thumb for the

internet is be careful where you put your mouse pointer. You never

know what might be lurking behind that harmless looking URL. Viruses

are always a potential risk if you do not recognise the sender of the

link. Even your friends can send you something nasty if they have

been infected with the virus themselves. That is why you might

want to bookmark this link. Feed this website a URL and it will spit

out a report that you can rely on. It is free and easy to use which is

great when you consider how much heartache it can save you. Some PC

security programmes Oprah this feature as well but if yours does

not, this is a good free alternative. -- offer. So feel you

need never suffer from viruses again.

I showed you an online contact card last month and now I will go one

better with a free business card up for your smartphone that led to

share contact instantly. Set up and leading your social account is very

easy and then you are ready to share. If you have somehow been

transported back in time and the person you are trying to connect

with does not have a mobile or at least the application installed,

you can also e-mail it straight from your hand said. And it gives

your meetings contexts, saving a GPS marker with a business card to

remind you where you met. This information is also stalled on the

dashboard along with any notes on meetings you want to add. It can be

very handy with the terrible memory I have. It isn't everything but

sometimes it is good to know how small something years, especially

when it comes to mobile technology. This website is not particularly

sophisticated but when you tell it the size of your monitor, it will

display items in their real size. If you are feeling generous, you

about the looting, it is worth remembering there are other

important stories as well. Like the crisis unfolding in East Africa.

ball-watching. Good morning. It may not be the

forecast you want at this time of year but we lose the bulk of the

wet weather and it is a slow improvement this weekend. After a

disappointing start, it may Brighton today. Bright rather than

sunny. There may be some rain Deraa -- towards the south-east. It will

be a mild start to our weekend across the UK, particularly across

central and eastern areas. It will be another warm and humid feel want

the news that rain to the south- east corner. Already we can see the

improvement along the Dorset coast and through the Isle of Wight. To

London at 9am, it will be cloudy, grey and wet. The same for East

Anglia. There will be an improvement eventually. Glimpses of

sunshine to the east of the Pennines. The cloud and rain that

is clearing from the Northern Isles. A wet start. A few showers across

western Scotland. A better morning in Northern Ireland but it will be

cloudy. 13 degrees expected with a light breeze. Cloud for Wales. It

will be a rainy morning. We are optimistic the crowd will tend to

live and bright and somewhat in one or two places as the rain eases.

Some sunny spells. With some sunshine coming through, it will

feel humid in the south-eastern corner. Temperatures around 21-23

degrees. Further west, stubborn thicker cloud resulting in lower

temperatures. There may be drizzly showers but on the whole, not a bad

affair. Taking a look at Saturday, the Kent coast baby affected with

drizzly weather. But we are hopeful of sunshine coming through on
