Even though it's an old app, Google Talk continues to be a really popular app. It's no wonder - it's reliable, easy to use and much simpler than some of the more flashy IMs out there. If you're just getting started with the app, or you have a few doubts, we've answered the top questions about Google Talk below. Take a look...

How to sign up

This couldn't be easier. You need a Google Account, which you can get here. If you have an email address that ends with gmail.com, googlemail.com or you've got a personalized Google domain, then you don't need to do anything - your login details are also your Google Talk login information.

Then, download and install the Google Talk desktop client. The installation process is very easy, and when you see the login screen appear, just enter the login details mentioned above. That's it! As soon as you see the main interface appear, you're free to start chatting!

Copy and paste is one of the most-used functions in Microsoft Word. In Word 2010, though, there’s a function called the Spike that might be even more useful for moving text and pictures around a document.

The Spike is an extended clipboard feature of Word 2010. It allows you to remove two or more items from different parts of a document and reinsert them as a group in a new location in the document.

This can be very handy for editing large documents, piecing together research projects, arranging agendas, compiling reports and more.

So you've been making masterpieces on your camera phone...but when you get your hands on the video, everything's upside down! If you're using super-app VLC media player, you'll be really pleased to hear that rotating it back so you can watch it comfortably is really easy. Even better, VLC lets you rotate freely, so even if your video is at a funny angle, you're guaranteed to be able to watch it perfectly straight.

Rotating video in VLC;

1. Open your video in VLC and pause it so you can fix it without missing anything
2. In the menu, go to Effects and Filters > Geometry and enable the Rotate checkbox
3. You'll then be able to rotate your video in real time, so you'll be able to spot exactly when you've managed to turn it back to where it's supposed to be!

Bear in mind that this is a temporary solution. If you want to rotate your video and save it with the correct orientation, your best bet is to use a video editor like VirtualDub or Avidemux. If you'd like a tutorial on this, let us know in the comments!

The recent closure of Megaupload highlights the risks of using a cloud based service to backup and store data. Of course, backing-up your data to an external hard drive isn't without risks but there is one that's significantly reduced - the threat of losing access to your data due to sites being shutdown.

We've already compiled and compared a list of other cloud backup solutions so here are five of the best desktop backup alternatives for Windows and Mac:

TimeMachine

(Mac):

Apple's easy to use discreet backup solution. Constantly backsup your data without slowing down your Mac so that you can effectively "go back in time" and restore files and data. Note however that some people have found it unreliable at times - it may start-off well but may become erratic over time.

SuperDuper!

(Mac):

SuperDuper! creates exact clones of your Mac's hard drive so you have a full backup of all your data, including permissions, user profiles and private settings. Simply select the target and destination drives and start backing up. You can specify exactly which files you want to transfer and which you'd like to omit.

Carbon Copy Cloner (CCC)

(Mac):

Carbon Copy Cloner is free, simple to use and backsup only those files and folders that you want it to. Just connect your external hard drive to your Mac, CCC will automatically detect it and off you go. You can also schedule automatic backups at specific times and create disk images with it.

Norton Ghost

(PC)

Norton's Anti-Virus is a nightmare but its backup solution is a much better package. Norton Ghost is probably the closest thing to Time Machine on a PC and backs-up your entire hard drive – or just selected folders – to another partition, networked drive or an external storage device. Norton Ghost can also create an exact copy of your hard drive with all the existing files, programs and settings and provides restoration points.

USB Image Tool

(PC)

USB Image Tool is one of the simplest PC backup solutions you'll find. It's free, straightforward and automatically detects USB devices connected to your computer and scans them before asking you whether you'd like to create an image backup or restore a previously backed-up image. USB Image Tool can create images of USB memory sticks and MP3 players that are mounted as USB drives.

Yesterday's big announcement by Apple was the release of iBooks Author and iBooks 2. iBooks Author is a Mac application and Apple's attempt at revolutionizing educational books whether they be textbooks, cookbooks, history books, picture books and more for iPad. With it, you can create all of the above and more via a classically easy to use Apple interface. iBooks 2 is the application you need to view publications created in iBooks Author.

To get you started quickly, there are lots of Apple-designed templates that merely require you to add your own text and drag and drop images.

To add interactive photo galleries, movies, Keynote presentations, 3D objects and more, there are simple widgets which make things very easy indeed. The widgets are one of the outstanding features of iBooks Author. They enable you to add everything from a photo gallery to a Keynote (Keynote ’09 v5.1.1 or later) presentation and can be easily identified in your Table of Contents. You can also add a voice-over to make it easier for sight-impaired readers to read your books.

Ever tried to watch AVI movies on your iPhone? Then you’ve probably already worked out that the Apple device sadly doesn’t support playback of AVI video.

Thankfully, there is a way around this issue and there are at least two ways to play AVI files on an iPhone, iPod touch or iPad. Here I’ll explain how it’s done, first by converting your video file and prepping it for your iOS device, or alternatively by using an app called Air Video to stream video files from your computer to your iPhone.

Do this…

Use a conversion tool to convert AVI movies to iPhone format. I recommend Format Factory because it’s free and it has built-in output settings for converting to particular mobile devices, including the iPhone.

Mozilla has released the latest Alpha version of Firefox - Firefox 11 Aurora. Most of the major changes in Firefox 11 Aurora are in the Android version, which now finally supports Adobe Flash and has a native Android interface. Syncing has been temporarily removed, however.

For Windows and Mac users the User Account Control panel has been withdrawn after installation and you can now import bookmarks from Chrome.

Other changes are mainly under the hood, including more support for HTML5 and Google's SPDY protocol for faster site loading can now be tested. In addition, there's support for 3D web page visualization and HTML5 video controls have been redesigned. There are no major changes to the appearance.

Note that Firefox 11 Aurora is an developmental release and therefore can be unstable and may not work with many add-ons. If you want the stable version (version 9), you can download it here for Windows and Mac.

Download Firefox 11 Aurora for Windows or Mac.

It seems fitting that the first OnSoftware post of 2012 should pay homage to some of the great articles we published last year.

There was much to talk about in the world of software and apps in 2011, and testament to this is that we published more blog articles last year than any other in our history. If you don’t have time to go back and read them all (there’s a staggering 581 of them!) then at least go back and revisit our ten most popular posts of last year in terms of visits.

The list makes for an interesting overview of what was on the minds of computer users last year (upgrading to Windows 7/Mac OS X Lion, getting onto Google +, social media privacy - and Minecraft!) Take a trip back down memory lane by checking out the posts:

When Tom put out his guide to getting onto Google + before anyone else, everyone wanted to be his friend.

It's been a long time in coming but the beta version of XBMC 11 has now been released. Version 11 "Eden" adds lots of new features and improvements to the open source home theater software for both Mac and Windows.

The most notable changes are Addon Rollbacks and vast improvements to the default skin Confluence.

There are also significant speed increases thanks to what's known as "Dirty-region rendering", a new JPEG decoder, a simpler, better library, additional protocol handling, better networking support, better handling of unencrypted BluRay content and structures, adjustable display refresh rates in OSX (to match the already available feature in Windows and Linux), AirPlay support, an upgraded weather service, and much more.

You can find details of all the new additions and changes to XBMC in the changelog.

Although not finished yet, there are also important changes in progress to XBMC Live to make it more like a full “*Buntu” version of XBMC with major changes to the boot and install process.

Skitch, the popular image annotation and screenshot tool for Mac, is now available as an iPad app. That means more possibilities for personalizing photos and sharing with friends and family, no matter where you happen to be.

In August Evernote purchased Skitch and has subsequently been adding features to the program to prep it for its release on iPad. This version of Skitch has a useful home screen that gives you a multitude of different options. You can edit an image on your iPad or snap a new photo, capture a screenshot, annotate a map to make directions even more understandable or even just sketch on a completely blank canvas. Skitch also has its own web browser with handy features that make marking up webpages quick and simple.

In addition, Skitch for iPad has numerous drawing tools that are all easy to make use of. You can move around objects on the image with your finger, draw arrows to highlight certain aspects of the picture, add in shape or text, crop the canvas as you like and use your finger for freehand drawing. When you're done, you can save your new drawings and annotations to Evernote and share via email, Twitter and more.

Best of all, Skitch for iPad is completely free and very easy to use. Sharing and editing images on the go has never been easier.

Mac users can get some free Skype credit by signing-up to test Skype's new "Click to Call" service which allows Mac users to make calls from directly within their browser.

The service is in closed beta and you have to take a survey first and sign a non-disclosure agreement with Skype to test it. You're then entitled to an unspecified amount of free Skype credit for calling landlines and mobiles as a thank you gift. In addition, a "larger gift" will be given to the top contributor.

Successful applicants will be contacted over the next few days and you can get started with the survey here. Remember that it's only open to Mac users.

Mozilla has released the final version of Firefox 9 beta meaning it won't be long before it is confirmed as the next stable version of Firefox.

The latest update features improvements to Javascript that Mozilla claims boosts performance by over 30 percent. Mozilla has also tweaked Javascript with something called Type Inference for faster loading times. The other improvement is greater theme integration and swipe navigation for Mac OS X users.

Mozilla's frequent update policy still isn't popular with users - especially because they don't seem to deliver major improvements and break add-ons. Let's hope when the final version of Firefox 9 is confirmed, the transition will be smoother and the improvements more noticeable.

You can download Firefox 9 beta final for Windows and Mac or just wait for it to update automatically.

Apple have just launched iTunes Match but what is it exactly? In a nutshell, it's basically part of iCloud and makes it possible to access your iTunes collection from anywhere with iTunes 5.1 or higher. This also provides a handy backup of your music if anything happens to your PC, Mac or iPhone.

In addition, iTunes Match can clean your iTunes library by replacing those tracks obtained from outside the iTunes store with official iTunes store versions. This is useful for example if you have lots of ripped CD's or music downloaded from other sites that either aren't labelled very well or are of poor sound quality. iTunes Match will replace poor quality tracks with 256kbps versions.

iTunes Match isn't a free service. It costs $24.99 a year which isn't bad if you're a heavy iTunes user on multiple devices with a rather disorganized music collection.

Note that once you've uploaded your iTunes collection, you can stream it to your Apple devices in the same way as you can with Spotify. There's also a 25,000 track limit although those you have purchased via iTunes don't count towards this total.

The initial scanning and uploading process can take quite a long time especially if you've got a large iTunes library. Once a song is uploaded, a cloud symbol will appear next to it to let you know it's done.

For Spotify users, iTunes Match isn't really offering anything new but for those that rely on iTunes a lot, it's a practical service.

Voddler has the potential to be a great film service although the lack of film choice in the Spanish pilot version and general usability still need much improvement for it to be really popular.

Just under two years ago we were on the first blogs to test and review video-on-demand service Voddler plus we brought you an exclusive interview with co-founder Mathias Tönnesson. We've now had chance to see how far it's come as Voddler starts a wider European-wide roll-out in Spain. Note that Voddler is still only available in limited regions.

Voddler started out as purely a desktop client but the company soon decided to integrate it with a web based service after numerous security breaches and complaints about usability from users.

To stream films in your browser, you need to download the desktop client. There is also an offline client available for download which allows you to play films you have paid for without a net connection.
