Opera have released version 10 of their browser, now with Opera Unite and Opera Turbo included.

Opera Unite gives your web browser the ability to deliver content as well as consume it. The standard download includes a number of Unite applications, with more available for download from the application directory. The bundled applications include a file sharing server that allows you to make files available to the world (as well as allowing the world to upload content to your machine), a virtual fridge door for you to share notes with friends and family (pictured), a media player that allows you to play content from your Unite equipped machine remotely, an instant messaging server, a photo sharing application and a web server for serving your own web content.

The inclusion of Opera Turbo in the new browser marks the migration to the desktop of a technology that has long been a key feature of Opera's Mini product. Opera Turbo speeds up your browsing session by compressing content at Opera proxy servers before delivering it to your machine - particularly useful for those on low bandwidth connections.

Opera 10.10 is available free from www.opera.com for Windows, Mac OS X and Linux.

We're intrigued to hear what you, our lovely readers, think about Opera's advancements. They have an excellent, solid browser base and some truly unique additional features... are you tempted to make the switch?

One program people I know miss when they've tried to switch to Linux is iTunes. Like it or not, Apple's desktop app has gained the reputation of being the place to buy music and video downloads. But iTunes on Linux? Fuhgettaboutit.

That leaves an opportunity for someone in the Linux community to step up and deliver an alternative. Enter Canonical, who may be preparing to do just that in time for the release of Lucid Lynx.

Over at LaunchPad, there's a blueprint called Ubuntu One Music Store which states its goal as "to deliver the ability to purchase music from within a desktop music player." There's nothing much yet for details on the associated wiki, so there's no telling yet what exactly might be in the works.

As Joe Panettieri points out at WorksWithU, Canonical CEO Mark Shuttleworth mentioned Amazon during a press call for the launch of Karmic Koala. Unlike Apple, Amazon was more than happy to show Linux users some love - offering a downloader for purchases from their MP3 store. They're also pretty chummy already thanks to that whole cloud thing.

Even if the Ubuntu One Music Store ends up being an affiliate app powered by Amazon, it could provide a decent revenue stream for Canonical. It's also one more feature that could entice users to give Linux a try on their desktop.

We've had a love-hate relationship with Adobe Air since it arrived on our desktops. Ram-hungry apps had us seeing red. Still, a few killer apps helped drive adoption - apps like TweetDeck, Times Reader 2.0, and DeskTube. As Air continued to develop, it got leaner and meaner and now version 2 has arrived in beta. Adobe Air 2 is now here, and it's ready to get down to business.

Air 2 features a number of tweaks, updates, and feature additions. For starters, the Air 2 ships with Flash 10.1 beta - which adds GPU acceleration support and so far seems to kick my CPU's ass less often. Air 2 also boasts tighter integration with operating systems and can now access certain mass storage devices like USB flash drives, digital cameras, and flash memory cards. Air 2 can also tap into your computer's microphone.

Webkit has been updated, as has the SquirrelFish Extreme Javascript engine. Those two changes combine for a reported 50% gain on SunSpider benchmarks. There's also added multi-touch and gesture support and better printing and networking (including the ability to listen for incoming socket connections). Got a gigantic display? Air 2 supports a maximum window size of 4095x4095 - a 42% increase, though likely not one you'll benefit from at home.

Processor usage and memory consumption have been addressed, with many Air apps reporting about half the CPU utilization of Air 1. TweetDeck on my system is using about 20Mb less RAM. More efficient use of my hardware? Now that you can enjoy at home.

For more details about Adobe Air 2 check out the embedded clip of Kevin Lynch's presentation from MAX or head over to Adobe Labs, where you can also download the new version. Downloads are available for Windows, Mac, and Linux.

So far, the Air 2 beta feels like a major step in the right direction for Adobe. As more developers begin taking advantage of the possibilities now available and optimizing their apps for the new version, you may just see some pretty cool things happening on Air 2.

Jay posted yesterday about the arrival of bookmark sync on Chromium for Mac, and it appears as though Linux users have been invited to the dance as well.

After finishing the updates on my Ubuntu 9.10 dual-boot, I gave the --enable-sync command line switch a go on my 64-bit Chromium install. Sure enough, sync is now working on Linux. Head to the wrench menu and press "Synchronize my bookmarks," enter your credentials, and within a few seconds your bookmarks appear.

The change is certainly making my work day a heck of a lot easier. With the LastPass extension already handling my logins and passwords and Chromium now providing cross-platform access to my bookmarks, jumping back and forth between Linux and Windows is a much smoother process.

Chromium (and Chrome) on Linux is shaping up rather nicely. I'm in agreement with the devs on this thread - it feels speedier than its Windows counterpart. With about 80% of my computing time spent in a web browser, Linux is becoming a more compelling option for me - thanks to the Chromium project.

1. Selective sync. Ability to choose which files or folders get sync'd to which computers.

2. Watch any folder. Sync folders outside the My/Dropbox folder (thus essentially replicating the functionality of SugarSync). This would be sweet, though I wonder how it would affect the current simplicity and performance of the app.

3. Share folders without forcing other members to lose space. I'd be interested to see how they handle this one. It could open up loopholes for vastly expanded storage space for groups of people.

4. Email files to Dropbox. Use an email address to upload files to your dropbox space.

5. Mac resource fork support. Perhaps the most cryptic of the requests. The resource fork is essentially metadata attached to the file that helps the Mac OS understand the file better. It defines things like custom icons, window sizes, menu definitions and the like. It is also how Mac OS can do extension-less file names. These things are generally stripped by backup programs (like Dropbox). This would be an extremely useful feature for Mac users.

Media center application Boxee has grabbed a lot of headlines over the past year or two, and for good reason: Boxee provides Mac, Linux, and Windows users with an excellent solution for watching internet video on a TV. While web browsers were generally designed for viewing text and images with video thrown in as an afterthought, Boxee was designed to look and feel more like a consumer electronics application that you can navigate from the couch with a remote control.

Boxee can access online video from services including Hulu, Joost, and BBC's iPlayer. You can use it to enjoy audio and video podcasts. And you can access local media stored on your hard drive.

But despite all of its features, Boxee is still alpha software. That's going to change next month. Boxee is set to launch the first beta version of its software at an event in New York on December 7th. I suppose the day will continue to live in Infamy, although I doubt that decades from now we'll still be talking about it as the date that Boxee went beta.

The new version will have a new user interface, improved navigation, a user-controlled queue, and a new TV and movie search function among other changes.

I have no idea if Egoboo's original creator named this thing, or if the name came later on after the mantle had been handed down a few times -- and I had absolutely no idea what that word meant... until I punched it into Google! Check out the definition, if you feel the need to know. If not, read on!

Egoboo is a (90 megabyte!!) 3D Rogue-like game. Rogue is a very, very old game -- the original adventure game, really -- and Egoboo builds on its legacy, throws in a little hack-and-slash... and it's even a bit of a RPG! There is loot, there are gribbly monsters that are out to eat your face, and there are plenty of pretty zones to explore (plus there's a map editor!)

To top it all off, it's fully cross-platform (Windows, Mac AND Linux) and has a thriving forum community. It's free of course. Oh, and It's quite brutal. I died several times very quickly, so I'd recommend reading the guide before you jump in.

Download Egoboo (yes, their site is so old it even uses frames! OK, iframes, but still...)

Distraction is the enemy of focus. If you work at a computer all day, the possibilities for distraction are limitless. One way to stay focused is to use the technique of a firmly regimented working period followed by a short break period that I first came across at Merlin Mann's 43 Folders site. His technique suggested using 10 minutes of work followed by 2 minutes of rest, but the recently popular Pomodoro Technique suggests using 25 and 5. Whatever periods you use, the cross-platform Adobe Air based Focus Booster application is just the timer you need to keep you on task.

Focus Booster is a tiny timer that allows you to set a work and rest period, then away you go. You can focus entirely upon your work knowing that a rest period is coming soon, and you can check out your Facebook / Twitter / blog comments / whatever it is you fancy when the time comes.

Skype has been providing cheap and free VoIP, chat, and video conferencing features for Windows, Mac, and Linux for years. But just because a program works on Linux doesn't mean it's open source, and the Linux client for Skype has been just as closed a platform as the Mac and Windows versions. That's not to say that developers haven't been able to build third party add-ons and tweaks for Skype. But the source code hasn't been available, which limits the ability of the open source community to really contribute to Skype for Linux.

But it looks like that's going to change. This weekend Olivier Faurax contact Skype customer support about the availability of an RPM package for installing Skype on Mandriva Linux, and he received a reply that indicated that the Linux client for Skype would be made open source in the near future.

I was a bit skeptical, since customer service folks don't always know what's going on in the minds of management, so I sent a request for more information to Skype's corporate communications office, and it turns out that yes, Skype does plan to make its Linux client open source in the future.

It's not entirely clear when the shift will take place. But it should make it much easier for third party Linux developers to ensure that there are up to date packages for Skype for a variety of popular Linux distributions including Mandriva, Ubuntu, PCLinuxOS, Fedora, and others. It also means that we could start seeing third party applications built around Skype code or more powerful third party plugins for Skype that enhance the application's functionality.

You can read the official statement from Skype after the break.

We've already mentioned other ways to power up Google Chrome. Before extensions arrived on the developer channel, Userscripts and bookmarklets were your only options. Both are still great ways to add some kick-ass functionality to Chrome. If you're running the stable or beta builds, you may want to stick to them for now.

• 10 handy Userscripts for Google Chrome users
• 15+ handy bookmarklets for Google Chrome (and other browsers, too!)

Now, onto the extensions!

The folks at Mozilla have released the first mockup showing what Firefox 4.0 may look like on Linux... and it looks an awful lot like the Windows version.

Firefox 4.0 isn't due out for another year or so, but the developers have already stated a few goals for the project. One idea is to move the browser tabs above the location bar. Another is to consolidate the menus into a few tabs that will hang out next to the location bar. Both movies will free up space, allowing more of the browser to be dedicated to displaying web pages.

If the end result looks familiar, that's because it looks an awful lot like the default layout in the Google Chrome web browser.

Mozilla has also released some mockups of Firefox 3.7 for Linux. One of the most notable changes is that the interface will be more consistent across platforms. Firefox 3.7 for Linux will use the same Forward/Back buttons as the Mac and Windows versions, for example. The edges of the browser, tabs, and other elements will also be curved rather than angled, which will make the browser look more like the mac and Windows versions.

At this point, both the Firefox 3.7 and 4.0 mockups represent proposed changes and not finished products, so things may change by the time these browsers are actually released.

We've been looking at Ubuntu 9.10 for a while now in anticipation of the big day. It's finally here, and the full release of Karmic Koala is now available for download.

As usual, there are plenty of ways to get your hands on the new OS. Unlike Windows 7, that includes certified, honest to goodness torrents straight from Canonical. They're already fairly well seeded, so P2P downloads should be nice and speedy.

To save you sifting through the massive list of links, here are the three big ones:

• Desktop, 32-bit [torrent] [direct download]
  
• Desktop, 64-bit [torrent] [direct download]
• Netbook Remix 32-bit [torrent] [direct download]

There's also a new release of WUBI [direct download] for those of you who want to do a hands-free Ubuntu 9.10 install from the comfort of your current Windows desktop.
