成人快手

Last night, the 成人快手 website went offline for about an hour - not something that happens very often. In fact, it was considered so unusual that for a while it was one of the most discussed topics on Twitter, with #bbcblackout becoming a top trending topic.

However, many of the explanations of what happened are hard to understand.聽 Controller of Digital Distribution Richard Cooper pointed to "multiple failures", citing failure in "aggregation of network traffic from the 成人快手's hosting centres to the internet" amongst other things. The editor of the 成人快手 News website, Steve Herrmann, simplified it further, saying that "routers" failed, as did the backup system - but what does this mean in layman's terms?

Simply put, websites consist of large amount of data - text, images, videos etc - which live on servers.聽 These are storage devices much like those found inside your computer, but many times larger.

When you type a web address into your browser, you are essentially giving it directions on how to find the server the website lives on. In turn, the website sends out directions on where your browser should look.聽 In fact, the 成人快手 website is so big that it is divided between quite a few servers - but in this case that's not where things went wrong.

What happened is that the technology that helps with the directions to the servers failed, as did all the technology that's in place as a back up measure.聽 So for just under an hour, the 成人快手 website appeared to have vanished - your browser couldn't find it, and in turn it couldn't send directions to your browser on how to find it.聽 It wasn't that the website had gone or been deleted - just that the connection wasn't working.

It's a bit like when you unplug your personal broadband router: not only can you not connect to the internet, but the internet can't connect to you.聽 That doesn't mean your computer doesn't work on its own, or that all your data is lost, or that you鈥檒l never be able to view your favourite websites again.

Of course, all technology breaks every now and then.聽 Fortunately the 成人快手 website is so large that it has dedicated teams working to keep it running 24/7 who managed to get most of bbc.co.uk back on its feet in under an hour.

Also, for more information about this story there's a useful article from 成人快手 News Technology.

Computer hacking is rarely out of the news, with reports today showing Australian Prime Minister Julia Gillard's emails have been accessed through a cyber attack on the Australian Parliament House email network.

Yet despite the attention that leaked information from high profile figures attracts, a study compiled by security firm McAfee has found that hackers are increasingly targeting intellectual property (for example, original ideas, inventions or designs) and business secrets from corporate networks.

Hackers can access information in a number of ways and if your credit card details have been taken, you'll soon find out. But McAfee's chief technology officer in Europe, Raj Samani, warns that with intellectual property the user may not even know information has been stolen as a cyber thief can just take a copy of it.

Last week I posted about Comic Relief鈥檚 Twit Relief campaign, which saw high profile tweeters auction off their 鈥榮uper follows鈥� for Comic Relief. The campaign raised over 拢285,000 with more than a hundred celebrities taking part and selling extras like a day out at the cricket or an evening of cocktails.

I spoke to several of the super tweeters taking part and was surprised to find out that they regularly interact with their followers and read a great number of tweets directed at them.

Duncan Bannatyne, another mega tweeter involved in the campaign, who regularly tweets to over 300,000 followers spoke to me about how small businesses can harness social media and what makes him tweet.聽

A few days before his lot went for 拢845 the star of 成人快手2鈥檚 Dragon鈥檚 Den told me he was more than happy with the amount he鈥檇 already raised.

鈥淚t鈥檚 a great amount of money that will do so much good for a fantastic cause.鈥�

There had been concerns that Twit Relief might create a class divide, so I wondered whether there was a part of him that was in it for the celeb rivalry or just a bit of an ego trip? His tone made it clear he couldn鈥檛 care less about competition.

鈥淢ost certainly not, I don鈥檛 care about this for me. It鈥檚 not about beating other people, it鈥檚 simply about using Twitter to help raise money for charity.鈥�

But with all the exposure he already gets I asked why he uses Twitter. 鈥淵ou get to interact with an awful lot of people,鈥� he tells me. 鈥淚t鈥檚 a great way of getting feedback on all sorts of things.鈥�

Bannatyne鈥檚 tweeting habits go far to support his claims about wanting greater engagement with his followers. My first communication with the entrepreneur from Clydebank was six months ago. I wanted to get out of my gym membership and tweeted him hoping to get a pardon from above. It of course wasn鈥檛 granted, but he did reply, which came as a surprise considering his status in the Twittersphere.

Examining his tweeting habits more closely I鈥檝e found that he regularly engages with his followers. Recent discussions have seen him give quite impassioned responses to issues such as bullying and you just have to look at the number of '@' comments to see how many people he tweets on a daily basis. So what sort of tweets is he likely to respond to?

鈥淚 prefer simple questions that require short or yes/no answers. I鈥檓 less likely to reply to a double-barrelled question.鈥�

This explains why he answered my Twitter query. It wasn鈥檛 an interview, nor a rude interrogation, but a simple question that he could answer easily 鈥� and that I鈥檇 probably have asked had I been sat next to him on a train.

As a man who knows business, would he recommend social networking to small companies?

鈥淎s much as you absolutely have to keep up-to-date with technology and not fall behind, when it comes to social networking I don鈥檛 think businesses should focus all their attention on it. You can get a phenomenal reach and Twitter can give you an advantage, but I think it鈥檚 a small one.鈥�

Both socially and in business, it鈥檚 important to remember the value of keeping things real and project who you are and what you do accurately. If you鈥檙e polite in person, don鈥檛 use the web to start being rude to people you don鈥檛 know.

If you run a business, make sure you know what you鈥檙e selling before you use social media to advertise it. We can鈥檛 expect the internet to do all the work for us and we shouldn鈥檛 hide behind it, but in our personal and professional lives it can help us unleash a huge amount of potential.

In the run-up to next year's Paralympic Games in London, disabled athletes and disability culture is set to become more prominent than ever before. I was born partially deaf, so I鈥檝e spent much of my life being very aware of everything deaf-related; from books to films and websites.

It's only in the last few years that I鈥檝e become more aware of different disabilities, and of news, arts and sport from a disability perspective. Here鈥檚 a few of the websites that have given me an insight into a rich and vibrant world I鈥檓 still getting to know.

Let's start with site. The broadcaster has the broadcasting rights for the 2012 games along with a great website that provides athletes鈥� video diaries, news items and inside stories. You can filter information by sport or by athlete, narrowing it down to the bits you鈥檙e interested in. There聽are聽also features on the history of the Paralympic Games, which is rarely covered in the mainstream press.

Additionally, the 成人快手 has an which will also help you find out who the key individuals are in the run up to 2012.

With blogs, opinion pieces, disability news and message boards, the 成人快手鈥檚 Ouch!聽blog has covered disability with humour, honesty and a fresh perspective ever since editor Damon Rose thought of the name for the site while taking a shower!

Regular columnists have their own unique take on disabled life, while the highlight of the site is the award-winning podcast, which is presented by comedian聽Liz Carr, and regularly manages to pull off the trick of being hilarious and informative at the same time.

There are two other disability sites I really enjoy. website has a range of sections for all tastes, covering a wide range of areas including travel, the arts and even motoring. There are聽some great columnists - look out for opinion pieces by Lorraine Hershon and Jane Muir in particular.

, meanwhile, is the website for Scope鈥檚 magazine, with news items, features and content from the magazine, balancing a focus on lifestyle with a strong sense of disability politics. I really enjoy the readers鈥� letters - which give a real insight into their views.

For people who are visually impaired, the 成人快手鈥檚 In Touch site features 鈥渘ews views and information for people who are blind or partially sighted,鈥� catering for people who would benefit from listening to programmes.

Another area of disability that has come to the fore in recent years is disability arts, with many artists across different media going on to achieve international renown.

features reviews of plays, films, music and exhibitions by disabled artists. There are聽also artist profiles and blogs (I enjoyed posts by Penny Pepper and Jon Adams), news, listings and an opportunity section that can help you get involved yourself!

Most importantly, the site gives you an idea of the newest work, with an insight into the thinking behind it. Sign up for their monthly newsletter to keep fully up to date.

If it鈥檚 theatre you鈥檙e interested in, are perhaps the best known disability theatre company, having worked with a range of disabled actors, writers and directors on a range of high-profile productions since they were founded in 1980.

Another prominent company is , a touring theatre company focusing on actors with learning disabilities. Then there鈥檚 , who produce plays presented in BSL (British Sign Language) and English, from a deaf cultural perspective. With all three companies, their sites help you find out about their current productions and where to see them (with performances in London and across the country) as well as the training, support and opportunities they offer.

I hope the sites I鈥檝e mentioned here give you a great start in finding out all about disability and particularly about disability sport before the Paralympics. Most of the sites also have a range of further links to other sites with even more information! So have a browse and explore a whole new world.

Charlie is a journalist and scriptwriter specialising in articles and films featuring deaf culture and sign language. He has written for the Guardian online and has contributed to programmes for Radio 4, while his films have won international awards. He also works in the arts, helping to make theatre accessible for deaf people.

As part of this year's Red Nose Day, Comic Relief has launched Twit Relief 鈥� or #twitrelief as you might have seen it referred to on Twitter.

It's the UK's first online auction of celebrity 'superfollows' where well-known tweeters will 'follow' the winning bidder in aid of Comic Relief. If you haven't yet delved into the Twittersphere and want to find out more, take a look at our article What is Twitter? by WebWise regular Guy Clapperton.

Lord of the Tweets himself Stephen Fry has already passed the 拢1,000 mark for his follow alone, despite the fact that the winner will be added to a seemingly not-so-exclusive list of 50,000 accounts which Stephen already follows. Yet where celebrities have such large audiences, a follow from them, without promise of friendship or even a cup of tea, is an accolade in itself. Twitter is a way of stamping your personality on the internet and if you've done some of the work yourself through a clever blog and regular updates, a celebrity follow can bring more attention to your own online brand.

Critics, like web personality Rob Manuel, are saying Twit Relief has "unexpectedly reignited class war" with others branding it an ego trip for the celebs involved. Yet with many offering a range of extras 鈥� from getting drunk with them to guided tours around a TV studio 鈥� they surely can't be that confident in the strength of their Twitter currency.

I spoke to a few of the super-tweeters taking part in the auction about their Twitter habits and was surprised to hear that rather than take the occasional fleeting glance at tweets from followers, they do in fact read all the ones that come their way. Oh dear. This means that presenter of the 成人快手's 'The Supersizers Eat', Giles Coren, must have seen my invite for a drink when he tweeted he was dining just 30 seconds from my flat. In my head he'd reply 'sure why not?' In reality I was a creepy stranger offering to ply him with alcohol in an East London flat. Eek! Needless to say he didn't reply.

The sense of a status divide is exacerbated by the simple truth that no one likes to be ignored and with some global megastars accruing up to 10,000 followers for every person they follow, there can't possibly be enough time for them to even read all their tweets, let alone reply. I struggle to find the energy to phone my own grandmother so I'd find being polite to 30+ people an hour challenging to say the least.

"If you've got a lot of followers, part of the pleasure is sharing stuff with them they might not come across in any other way" - Caitlin Moran

There's no doubting that some use Twitter to elevate their celebrity throne, or to promote their own products from perfumes to albums, but for many others, it's a genuine way of saying what's on their mind and engaging with their audience.

Times columnist Caitlin Moran has amassed almost 70,000 followers yet says she still reads all the tweets she receives, and estimates she replies to about one in twenty. Fellow writer India Knight has a substantial following of 30,000 and says she responds to about 75% of all tweets. Yet Knight doesn't seem to take her tweets too seriously. "How much are my tweets worth? Absolutely nothing, they're disposable nonsense" she tells me - "great in the moment, but completely ephemeral! Still, I hope my lot raises as much as it possibly can. Money buys malaria tablets so how can that be anything other than a good thing?"

"I love receiving and responding to quirky tweets. It鈥檚 all part of the joy of Twitter" - Jon Snow

I caught Jon Snow as he was about to board a flight to Japan to cover another tragedy that is now also at the heart of a global campaign for donations. The Channel 4 News presenter has passed 56,000 followers and reads all tweets that come his way, noting that most he responds to are about his choice of tie. When I ask him how much his tweets are worth, it's evident he's not taking part in Twit Relief to massage his ego. "I think I'd pay about 5p for my follow, but I'm throwing in an extra of a guided tour around the newsrooms, so let's say oh, five thousand pounds! It's all for a very good cause."

Class divide or no class divide, if a celebrity's followers are willing to donate to charity for a Twitter nod, then surely it's a market we shouldn't feel too worried about exploiting.

Hajar is part of the WebWise production team and has also made award-winning programmes for 成人快手 Radio. In her spare time she loves reading, writing and singing.

Earlier this week, I went to see Charlie Brooker present a hilarious new series of his Radio 4 comedy show So Wrong It's Right, starring some of the UK's finest comedians - for free.

In fact, during my time at the 成人快手 I've been to Broadcasting House to watch The Now Show being recorded, to Pinewood Studios to watch David Mitchell's team triumphing in a great episode of Would I Lie To You, and to the legendary studios at 成人快手 Television Centre more times than I can remember to watch great shows like You Have Been Watching, Grownups, The Omid Djalili Show and The Hairy Bikers' Cook Off, and all I had to pay for was my bus fare.

However, don't think for one second that this is a perk of my job. Not at all. In fact, anyone can go and watch a TV or radio show being recorded - as long as, like me, you're prepared to sign up on the website and queue with everyone else. That's right: you too can indulge in your secret passion for David Mitchell, Alexander Armstrong, Sandi Toksvig or even Bruce Forsyth by seeing them live in the flesh for absolutely nothing.

And this isn't just something for Londoners - most of the TV and radio shows might be recorded in big studios near the capital, but there are a plethora of one-off recordings and events held across the whole country. For example, the touring Bang Goes The Theory road show is very popular, and summer wouldn't be the same without the Proms, quite correctly billed as "The world's greatest classical music festival".

What's more, you can even come and have a nosy round our studios. If you want to see what your local 成人快手 stations are up to and how they work, you can come and look round a whole range of 成人快手 offices through the Tours website. I've been on the tour of Television Centre with friends and got to see areas of the 成人快手 even I, as a staff member, don't usually get to see.

So, with all this in mind, I highly recommend giving the 成人快手's Shows, Tours & Events site the once-over. Every time I look I find something worth going to, but if your favourite show isn't on there, don't despair: many shows are produced by independent production companies, who use other websites to advertise for audience members. External agencies include SRO Audiences (for shows like The Graham Norton Show, Dancing on Ice, Live At The Apollo and Mock The Week) and Applause Store (for Britain's Got Talent, Top Gear, Never Mind The Buzzcocks and QI).

You might have noticed that some of those programmes aren't aired by the 成人快手: that's because it's not just the 成人快手 looking for audience members. Broadcasters like Channel 4, ITV, Sky and more are always looking for people to come and enjoy their shows. You can register your details and apply for tickets for the shows you're interested in. You might not get accepted every time, but you could get to see your favourite programme recorded - without spending a single penny. And it's worth mentioning that the more times you attend the more likely it is that you'll be successful in getting tickets the next time you apply, as all of these ticket-suppliers keep a record of who can be relied upon to turn up.

In the mean time, while you wait for your tickets to come through, that great Radio 4 comedy I went to see being recorded, So Wrong It's Right, starts from tonight (Thursdays at half six) - and I highly recommend it.

How do you know what's going on in Libya? I doubt you're getting your first inklings from the next day's newspapers.

Today, news usually appears first on the web, or on social networking sites such as Facebook and Twitter. When there's an earthquake, for example, people tweet about it while it's still happening, and journalists now use Facebook updates, tweets and "twitpics" (photos uploaded with links from tweets) as sources. People are everywhere that journalists are not.

Journalists still do valuable on-the-spot reporting. Journalists and editors still spend hours filtering and interpreting vast amounts of material to compile pithy reports that tell compelling stories. But the idea of news is changing, and journalism is slowly moving from creating to collaborating and curating.

Obviously the news cycle now runs faster than ever. When I started writing about computers for the Guardian newspaper in 1983, news items appeared the next day but features could wait a week or two. With websites and blogs, stories usually appear within hours or minutes, and thanks to webcasts and live-blogs, you can even follow events as they unfold in real time.

But some things have been lost, including context and a sense of community. On the web, it's not so easy to tell the leading story from the humorous filler at the bottom of the page. The old journalistic trick of getting two people to present opposing views on facing pages has become a recipe for disaster, with the "pro" and "anti" versions being read by different groups of people.

Search engines like Google enable people to pick the stories they want to read, but there is no simple way of providing variety or balance. There's a lot to be said for the virtual personalised newspapers such as DailyMe. However, if people only see stories about topics in which they have already professed an interest, how will they learn anything new? If you buy a real newspaper every day, at least you'll get a range of topics and usually a range of views. Newspapers have to be broad enough to appeal to large groups of people: they can't be as specialised as blogs.

On the web, communities are shifting from newspapers to news aggregators. Instead of being a loyal Guardian reader, you might be a loyal Reddit or Digg user, because these sites share links to thousands of different news sources. This type of aggregation is terrific, but it can skew reporting and presentation. Everyone loves hits, and like pop music, news is becoming a hits business.

Today, as print circulations and advertising revenues decline, some companies are trying to build "gated communities" (registered members only) on the web. The hope is that if people are willing to pay for access to, for example, The Times and The Sunday Times, which are now behind "paywalls", the publisher gets some gate money and can also charge advertisers higher rates to reach them.

As a long-time newspaper journalist, I'd like this idea to work. As someone who was on the internet before the web was invented, and who now blogs for a living, I'll be amazed if it does.

Nowadays, people are often more interested in reading the same story on five or six different websites than in reading five or six different stories on one website.

I used to believe in a science fiction solution: the newspad. Everyone would have a thin, flexible paper-like LCD screen at home, and each day's newspaper would simply be downloaded overnight for reading over the breakfast table. Everything would be the same - news, features, adverts, etc - except the delivery system.

That's no longer believable because nobody wants a single source of news delivered at a single time, and nobody wants to pay 拢1 a day for it. Today, news has to be instantly available everywhere, from an infinite number of sources. If you're on Twitter, or a similar site, you may even be involved in making it.

Newspapers now face a difficult transition from paid-for physical copies to free virtual ones, and we don't know how that will turn out. However, it's clear that things ain't what they used to be. For better and worse, the web is remaking the news.
