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

    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.

    Apple iPad 2 official Demo and Presentation

    Next Up: iPhone 5

    Next week Apple will spill the beans on the iPad 2, which can only mean one thing: It's time to start focusing on the iPhone 5 -- which will (probably) be announced in June.

    iPhone 5's digitizer panel?Like clockwork, 9 to 5 Mac on Friday uncovered a photo from a Chinese reseller of Apple parts that will get that process under way.

    The site suggests the unconfirmed part could be the digitizer panel for the next iPhone. Interestingly enough, the part appears to have a larger cutout section for a screen which could support earlier reports from DigiTimes that the new model will feature a four-inch display to compete with some Android devices.

    Besides being unconfirmed, the photo is problematic because the part doesn't appear next to anything -- giving it no scale. It could just as easily mean that the upcoming iPhone could be smaller if the screensize remains the same and the bezel shrinks. The screen could also be any other size, there's really no way to tell.

    Regardless if this is a legit part or not, it seems like Apple has a few changes in store for the next iPhone besides a larger screen.

    Jonny Evans of Computerworld reported last month that the new model is expected to run on a multi-core A5 CPU and may feature a dual-core graphics core. Evans also suggests that Apple will be getting into the NFC field after hiring veteran Benjamin Vigier as the Mobile Commerce Manager.

    Stay tuned. The iPhone 5 rumor mill is sure to heat up in the coming months. iDealsChina, the website that leaked the part photo, seems to hint that more photos will be popping up soon.

    Nokia embraces Windows Phone 7 as its primary mobile OS

    Nokia and Microsoft just dropped a bomb - the two leading companies will be joining forces for an extensive collaboration. Windows Phone 7 becomes the primary smartphone OS for Nokia, but Symbian and MeeGo remain in the picture as well.
    Following the recent internal memo of new CEO Stephen Elop, we knew there was change afoot, but this is a major change. It has been rumored many times and denied by Nokia, but now it's official and confirmed from the top of both companies.
    Changes at the top of Nokia saw big changes - the Group Executive Board is being replaced by the Nokia Leadership Team. The company will also restructures itself into two distinct businesses - Smart Devices and Mobile Phones. Each unit will be responsible for developing its own devices and marketing them.
    Both divisions will be headed by women - Mary McDowel will head the Mobile phones division, while Jo Harlow will take over the new Smart Devices division.
    Mobile Phones will take over the feature phone business, while Smart Devices will inherit Symbian and MeeGo and work closely with Microsoft to develop the new Windows Phone devices, but also offer their expertise to enhance the OS and also offer hardware know-how (in areas like imaging and more).


    Nokia and Microsoft will work to offer Windows Phone 7 devices in a "larger" range of price points (WP7 is exclusively high-end now) and countries, but also share a common development roadmap.
    Nokia will take an integral part in the future development of the Windows Phone 7 platform by using its expertise on hardware optimization, software customization, language support and scale.
    The Nokia/Microsoft cooperation runs deeper than the mobile phone manufacturing, they will build a whole ecosystem. Nokia Maps will become a core part of Microsoft's mapping services. Microsoft's Bing and adCenter will provide search and advertising services on Nokia Devices.
    The former Ovi Store will be merged into the Microsoft Marketplace. Nokia's operator billing with many operators will make it easier for consumers to purchase things from the Marketplace in countries where credit cards are less common.

    Symbian is still a big part of Nokia - they plan to sell 150 million devices in the coming years. However Nokia plans to turn Symbian into a "franchise platform", to recover at least a part of Nokia's investments in the platform.
    As for MeeGo, it will become an open source mobile operating system, focusing on next-generation products and long-term market exploration. There will be a MeeGo device out this year (maybe it will be announced this Sunday at the MWC) but as a whole MeeGo steps off as one of the main platforms for Nokia.
    Series 40 will be an essential part of Nokia's "web for the next billion" strategy. The strategy aims to bring affordable Internet access to developing markets with Ovi Browser (this one?) and web apps.
    Unfortunately, developers won't be able to use Qt as their programming platform for Windows Phone 7. Qt will still be the means to create apps for Symbian and MeeGo, but Microsoft will provide their own tools for creating Windows Phone 7 apps.
    Nokia plans 2011 and 2012 to be the transition years, in which they will build their "winning ecosystem" with Microsoft. After that they expect their net sales to grow faster than the market and the operating margin to reach 10% or more.
    Stephen Elop and Steve Balmer posted a joint open letter on Nokia Conversations, discussing the future. They finished with this:
