Deleting pictures and data in social networks



A comment or photo is quickly and easily posted onto a social online network. But how can you get rid of them again? Users of Facebook and some other social networks can delete the comments and pictures that they post on their walls.
“As long as you have an account, users can delete by themselves wall entries on the profile pages of others,” says German social network spokesman Martin Boit.
Just call up the comment you want to delete, roll the mouse over it until an X appears in the corner and click on it — that’s all.
Those who would like to remove their tracks must only remember where they left them. Clicking on those entries and pictures is just as easy as posting a message. But you must remember that once you delete something, it cannot be restored if you change your mind.
Facebook and other platforms also offer the opportunity to completely delete their profile.
“Every Facebook user is the owner of their data and has full control of it. This includes the fact that every user can delete their data on Facebook,” said a Facebook spokeswoman.

Versions - 20.12

2012 hasn't even begun, and yet we've already got a number of reasons to look forward to the coming year. Let's take a look at some technology coming our way the next year



Operating systems
As far as operating systems go, 2012 looks set to be a bumper year. With a slate of Windows 8 tablets expected to release, we'll finally get a proper look at Microsoft's vision of the future of Windows. Not to mention Windows Phone 8, which also should make an appearance before the year is out.
On the Google side of things, Android 4.0 (aka Ice Cream Sandwich) has been heralded as the best version of Android yet; and devices running Google's latest should start making their way to our shores in early 2012. The long-rumoured Google Tablet appears set to become a reality next summer.
As always, huge things are expected from Apple's next OS updates, iOS 6 andMac OS X 10.8; as of now, though, little is known of either. Similarly, BlackBerry fans will have to wait until the end of the year for a glimpse ofBlackberry 10.
Gaming consoles
We can't wait to finally see Nintendo's Wii U in action. The original Wii revolutionised motion-control in gaming and became the most popular console in the world; but it's since faded a little due to dated hardware and a dearth of quality third-party titles.
The Wii U represents Nintendo's answer to those criticisms — with HD graphics on par with the current competition, a stellar legacy of innovation and Nintendo's formidable stable of games, the Wii U is easily one of the most anticipated 2012 launches in gaming.
Right up there with the Wii U, though, is the PlayStation Vita. Going by its powerful specifications alone, the Vita is quite exciting; when you also consider that it claims to deliver PS3-level graphics and a full array of control options in a hand-held device, it becomes positively drool-worthy. As always, rumours abound about the next generation of Microsoft's and Sony's consoles.
Will 2012 see the release of the PlayStation 4 or Xbox 720 or whatever else they might be called? It's unlikely; however, given all the evidence pointing to something big coming our way at the end of next year, an announcement or two doesn't seem outside the bounds of possibility.
Truly smart
Meanwhile, ASUS is keeping the flag flying with its sheer out-of-left-field designs. The company that gave us the excellent Transformer Prime tablet — which turned into a capable net-book with the addition of a keyboard dock — is once again pushing the boundaries with the ASUS Padfone.
The Padfone is a 4.3-inch smartphone (reportedly running Android 4.0 at launch) that integrates with a 10.1-inch display dock, effectively enabling it to serve as either a phone or a tablet. And if that wasn't enough to pique your interest, the Padfone will also be running on a quad-core Tegra 3 chipthus making it one of the most powerful smartphones around.
Say cheese!
In terms of sheer potential, the gadget we're most intrigued is from the field of photography. We're not alone in having such high hopes for the Lytro Light Field Camera; it's been described as the biggest thing to happen to photography since it went digital.
What's all the fuss about? Well, the Lytro camera uses light-field technology to capture all the light information from a given scene comprehensively enough to create what the company calls ‘living pictures'. You can adjust the focus of these living pictures at your own leisure, or even convert them into 3D images.
While it does have its limitations right now, the “shoot now, focus later” USP that Lytro is going with is undeniably exciting, and provides a solid platform to build on. The technology used in the camera isn't new; however, until now, it's solely been the province of those with research labs and supercomputers.

The desktop in your palm: Nokia N900



With the Nokia N900, the Finnish company dumps Symbian for this chunky, hugely powerful ‘pocket computer' that runs the Maemo OS. Nokia has broken the mould with the N900 replacing the company's usual Symbian OS with Maemo, which is a more advanced system.


The hardware is similarly powerful, with a pull-out QWERTY, a 600MHz ARM A8 processor, 1GB of RAM, 32GB of storage and a touch screen that's lushly high resolution, even if it is sadly only resistive rather than capacitive.


As a result, it's uncommonly wide and chunky, but it is excellent for viewing video and browsing the web, and Maemo is easy to use, despite a sometimes unresponsive touch screen – and this is one of the dwindling band of phones that still comes with a stylus. Nokia has added a little kickstand for hands-free video viewing.


Despite the open-source nature of the OS, the Maemo application portal is somewhat short of options, and while Facebook is included, this phone isn't geared for social networking. However, multiple IM clients and VoIP for cheaper calls are on offer.


The web browser is the main attraction on the N900. It seamlessly shifts between Wi-Fi and 3G connectivity, offers full Flash compatibility and packs the new Firefox Mobile browser.


The only problem is that the power of it makes you miss the multi-touch slickness of the iPhone or Desire all the more.


The music player on the N900 is also great fun. There are widgets for easy access on the home screen and it'll sync tracks from your Windows 7 home PC too. Storage is impressive, with 32GB on board and the option to add a further 16GB through microSD, and internet radio is supported out of the box. Slick wireless home networking is also built in. Despite a low quoted talk time, in reality the N900 has the best performing battery on test, making this phone an attractive option to anyone not put off by its ugliness and lack of slickness in other areas.


LOVE : The power of the N900 is in its processor, and because Maemo is open source, the web is awash with easy ways to modify and upgrade it


HATE : Most people will find it too big, in our view. The resistive touch screen can be frustratingly inaccurate at times


I SAY : The N900 is a powerful, versatile device, but over-sized, ugly and sorely lacking the multi-touch slickness of the Desire or iPhone

BlackBerry Bold 9700



The emailing executive's weapon of choice, the BlackBerry Bold 9700 is the smartest BlackBerry to date. The BlackBerry Bold 9700 is the best RIM has to offer, with the most tech crammed into any in the BlackBerry range, a quality feel and nicely tactile QWERTY keyboard.


The 9700 is a top-drawer messaging device. From the simple email set up to integrated multiple IM clients – Windows Live Messenger, Google Talk et al – and the single, streamlined inbox, it's a compulsive chatterer's dream come true.


The QWERTY keyboard is excellent, perfect for emailing on the hoof, while battery life is better than average, giving you about a day and a half of frequent emailing.


In addition to the headline features, you get a rather average 3.2-meg camera with flash, fast HSDPA browsing – this also helps with email attachments and of course you also get A-GPS with BlackBerry Maps and Wi-Fi.


Onboard memory is only 256MB, but there's a microSD slot and the 9700 ships with a 2GB card.


The 9700 runs the well-rounded BlackBerry 5.0 OS, which integrates messaging, phone and app functions so well that you won't even know you're multi-tasking.


The BlackBerry App World is under-stocked when compared to Apple's huge, ever-growing App Store, but the apps here do at least favour usefulness over time wasting.


‘Gwabbit', for instance, pulls out new contacts from your inbox.


With basic but functional music controls and a 2.4-inch screen, albeit a fairly high-res one, the 9700 isn't any kind of multimedia giant, but it does the job. There's a proper headphone socket, too.


The Bold 9700 is not the best all-round smartphone and anyone looking for multimedia features should go elsewhere.


However, for those who absolutely have to be in touch at all times, this can't be beaten.


That there's a respectable set of secondary functions is just a bonus, adding to the overall feel of quality and reliability that this phone effectively exudes.


LOVE - The Bold is a fantastic device for messaging, with a great keyboard and rock-solid email reception and delivery


HATE - The OS isn't as stable as some other smartphones, and the App World could do with a few more wares to sell


I SAY - The best BlackBerry out there at the moment. When the BlackBerry OS 6.0 arrives, it'll be even better

JooJoo takes on the iPad



With the war between tablets heating up, the iPad is under pressure yet again, this time from the JooJoo developed by Singapore-based Fusion Garage. A larger screen, USB connectivity and a web-based Linux OS are just some of the perks it offers, so lets watch these two tablets fight it out!


Experience
The JooJoo should be as responsive as the iPad, and there's a choice of small keyboard for one-handed typing or a standard-sized one. Multi-tasking and Flash support also give the JooJoo an edge. However, it seems unlikely that the JooJoo will be the untrammelled pleasure to use that the iPad is, and as for apps and buying books, music and movies, it's a clear second best.
Winner: iPad


Processor
Inside the JooJoo you'll fi nd a 1.6GHz Intel Atom processor compared to the iPad's 1GHz A4 microchip. The JooJoo's extra speed allows it to multi-task with no slowdown – just swipe your finger to scroll between open windows, and flick one away to close it.
Winner: JooJoo


Battery
Both have rechargeable lithium polymer batteries, but the iPad has double the lifespan, giving ten hours with Wi-Fi on to the JooJoo's five.
Winner: iPad


Camera
The JooJoo has a front-facing camera for video conferencing – this is rumoured for the next-gen iPad, but isn't there on the existing model.
Winner: JooJoo


Screen
The JooJoo's screen is bigger than the iPad's, at a whopping 12.1-inches to the iPad's 9.7. The 1366x768 resolution means it's able to show videos in 720p HD too.
Winner: JooJoo


Operating system
Instead of a desktop OS, JooJoo uses a web-based, Linux one, so you'll need to be online if you want to use it – hence there's only 4GB of storage compared to the iPad's 64GB. That's fine for basic computing, but not if you want to store media.
Winner: iPad


Portability
The JooJoo's bigger screen makes it a hefty 1.1kg. The iPad's just 0.68kg.
Winner: iPad


Connectivity
The JooJoo sports a USB port, unlike the iPad. It also has nWi-Fi and Bluetooth 2.1+EDR, just like the iPad.
Winner: JooJoo


Final verdict
There's a lot to like about the JooJoo. It's got a great screen, it multi-tasks and has Flash compatibility, and the look and build quality are Apple-ishly impressive. If you want a tablet mainly for web browsing and so don't need much storage, the JooJoo is a top device. Else, it's iPad all the way…
