Linux Kernel 3.0 Features, What’s New


Linux Kernel gets next milestone, Linux 3.0 is now available to the general public.
The announcement of Linux 3.0 comes from the founder Linus Torvalds himself as he mailed it to the Linux Kernel Mailing list.
“As already mentioned several times, there are no special landmark features or incompatibilities related to the version number change, it’s simply a way to drop an inconvenient numbering system in honor of twenty years of Linux. In fact, the 3.0 merge window was calmer than most, and apart from some excitement from RCU I’d have called it really smooth.”
Beyond the numbering scheme change, this kernel includes POSIX alarm timer support, a just-in-time compiler for BPF packet filters, a new sendmmsg() system call, ICMP sockets, the merging of the Xen backend driver (completing the long process of getting Xen Dom0 support into the kernel), namespace file descriptors, and more.
Other New Features in Linul Kernel 3.0

    1. Btrfs: Automatic defragmentation, scrubbing, performance improvements

    ICANN Approves New Top-Level Domains, So Prepare For .Whatever


    A handful of not very descriptive top-level domains, such as .com, .net, .org, as well as country-specific TLDs are  what the web is currently made of, but this is about to change drastically.
    ICANN (Internet Corporation for Assigned Names and Numbers), the international authority over top-level domain names, has approved the expansion of generic TLDs which will allow companies and organizations to create domains for their branda (such as .coke) or simply create generic names (such as .car or .green).
    The option won’t come cheap, though: The application fee alone is $185,000, and the annual fee is $25,000. Still, we can imagine large corporations spending millions on these very soon. If you’re in the business of making phones, owning a “.phone” TLD sounds like a great idea — if you can afford outbidding other phone manufacturers.
    “ICANN has opened the Internet’s addressing system to the limitless possibilities of the human imagination,” said Rod Beckstrom, president and CEO of ICANN. “No one can predict where this historic decision will take us.”
    We can safely predict one thing: Expect lots of legal disputes over company trademarks with regard to new TLDs.
    Applications for new generic TLDs will be accepted from January 12, 2012, to April 12, 2012. New domains should appear within a year.

    Skype to be sold to Microsoft


    One of the largest and most interesting of the social media start-ups of late has definitely been Skype. The video messaging system, which allows users to video message friends and families long distance, and even routes phone calls through the internet for a nominal fee has been a huge success. With the advent of webcams coming standard on most laptops and the world looking for even more ways to connect, Skype has become a major asset in the media industry.
    That, I suppose, is why there was such competition to buy them, but in the end Microsoft won out. The deal, done through investor group Silver Lake, reportedly cost Microsoft $8.5 billion – in cash. Microsoft’s press release from their news site asserts that the deal will help out both companies, bringing a wider audience to the Skype market and boosting Microsoft’s communications portfolio.
    The press release goes on to highlight that Skype will now be connected with Microsoft’s phone systems as well as with Xbox Live and Kinect, popular gaming devices. Therefore, Skype now has more avenues to connect via messaging, and Microsoft can add them to their long list of successes.
    Skype, which was founded in 2003, was originally bought by eBay in 2005 and then bought by Silver Lake in 2009. Since that acquisition, Skype has shown vast improvement and reach over its now global market, making it a viable option for Microsoft to buy.
    Of course, these types of deals take time and there are many more hoops the deal must jump through in order to be legitimate. Despite this, Microsoft’s press release states that they hope the deal will be settled by the end of this year.
