Linux Mint releases Cinnamon, GNOME 2.x style desktop

Clement Lefebvre, lead developer of Linux Mint, has announced the first “fully stable” version of its new GNOME 2.x-like “Cinnamon 1.2? fork of the GNOME 3.x desktop environment is now available for not only Mint, but for Ubuntu 11.10, Fedora 16, OpenSUSE 12.1, Arch Linux, and Gentoo.

The Cinnamon interface looks and works a lot like the popular GNOME 2.x interface, but it’s built on top of the GNOME 3.x infrastructure. It was created because many people, including Linux’s creator, Linus Torvalds dislike the new GNOME 3.x interface. Lefebvre tried to work with the GNOME developers to make a more user-friendly GNOME, but they weren’t interested.

As Lefebvre explained when he launched the Cinnamon project, “I’m not going to argue whether Gnome Shell is a good or a bad desktop. It’s just not what we’re looking for. The user experience the Gnome team is trying to create isn’t the one we’re interested in providing to our users. There are core features and components we absolutely need, and because they’re not there in Gnome Shell, we had to add them using extensions with MGSE [Linux Mint Shell Extensions for Gnome 3] and since “We’re not interested in shipping Gnome Shell ‘as is,’ or in continuing with multiple hacks and extensions,” so Lefebvre and his team started working on Cinnamon.

Now Lefebvre states the Cinnamon “APIs [application programming interfaces] and the desktop itself are now fully stable!”. While documentation is still missing, Cinnamon brings back the GNOME 2.x style interface and adds new desktop effects and layouts, a configuration tool, and five new “applets.”

Closing Megaupload unlikely to even slow piracy down

The U.S. Department of Justice working in conjunction with New Zealand’s law enforcement agencies has taken down the popular file-storage and sharing site Megaupload. So, since Megaupload has been shut down, Internet piracy has gone down significantly, right? Right? Well, probably not, NPD market researcher Russ Crupnick said, “Only about 3 percent of the U.S. Internet audience relied on digital storage for legitimate purposes or piracy in the third quarter.”

So where is the file piracy going on? The same place it always has been: over BitTorrent and other peer-to-peer software powered networks. According to Crupnick, “Peer-to-peer systems like BitTorrent, which have little central coordination and are harder to stop, still have about three times as much usage among consumers as digital lockers.”

BitTorrent file sharing may account for far more than just 9% of Internet traffic. The latest research by Sandvine (PDF link), a broadband solution provider and analysis firm, shows that BitTorrent traffic took up 13.47% of all Internet traffic in the third quarter of 2011.

Beyond the desktop: Ubuntu Linux’s new Head-Up Display

Mark Shuttleworth, founder of Canonical Ubuntu Linux’s parent company, has announced that Ubuntu will be adopting a radical new change to the interface that will do away with the “menu” in the Windows, Icons, Menus, Pointer (WIMP) interface, which has defined the desktop for the last thirty years.

Shuttleworth states, “The menu has been a central part of the GUI since Xerox PARC invented ‘em in the 70?s. It’s the M in WIMP and has been there, essentially unchanged, for 30 years. We can do much better!” This new interface, which will first appear as a beta in April’s Ubuntu 12.04 release, is called Head-Up Display.

Weekend Anonymous attacks bring down major websites

The Internet-based hacker and protest group Anonymous is still ticked up by the Department of Justice’s (DoJ) takedown of Megaupload. Last week, Anonymous took down the DoJ, the Recording Industry Association of America (RIAA), the Motion Picture Association of America (MPAA), and Universal Music with a Distributed Denial of Service (DDoS) attack. Over the weekend, Anonymous brought down CBS, Universal Music, and Vivendi. Will Facebook be next?

While Universal Music and Vivendi, the French media giant that owns Universal, were brought down by a DDoS attack, CBS, ZDNet’s parent company, was hit by a Domain Name System (DNS) poisoning attack.

In the CBS attack, it appeared that the site itself had been hacked and all its content deleted. That wasn’t the case. The CBS site was fine. What actually happened was that DNS record for the site’s IP address was changed to a fake site that contained a single blank page. IF you’d attempted to reach any of CBS’s sub-sites, for a TV show’s page for example, you would have gotten only a generic 404 Not Found error message page.

The poor get poorer and the rich get richer with Apple’s iPad-based textbooks

Apple’s iBooks2’s reinvented textbooks really are something. They’re gorgeous, they’re fast, they’re real-time interactive with up to date information and they’ll only cost $14.99 or less. But, to use them, you’ll need an iPad–minimum list price: $499.

Can you afford that for your kids? Can your school board? I could, but I’ve been lucky enough to do well in my career and I only have the one daughter. There’s certainly no way that any county I’ve ever lived in during my life in West Virginia, Maryland, or North Carolina could afford to give every student from K to 12 an iPad. They’re lucky when they can provide any kind of computer seat for each kid.

That’s why there have been programs like the so-called $100 laptop: the OLPC (One Laptop per Child). The OLPC project aimed to put first low priced notebooks, the XO-1.5 and now tablets, the OLPC XO Tablet, into the hands of kids who don’t go to private schools.

These XO Tablet is powered by a 1GHz Marvell Armada PXA618 processor, and have a mere 512MBs of RAM. It can run a minimized version of Red Hat’s Fedora Linux with the simplified Sugar interface on top of that and it can also run Android. Price: $100.
