Cloud computing represents a fundamental shift in the way technology services will be delivered to enterprises, forcing IT firms to re-look at how they operate now, according to Pat Gelsinger, chief executive officer of VMware, which provides software that enable creation of cloud computing infrastructure within corporate premises.

Gelsinger is convinced that not all major IT firms (including Indian ones) will survive this wave of technology transition. Change may mean sacrificing revenue in the short term said, Gelsinger, an Intel veteran rumoured to replace the retiring incumbent Intel CEO Paul Otellini, a rumour he denied.

Berlin filmmaker Sam Muirhead is attempting to live a completely open source life for one year. Here’s why.

The phrase ‘Open Source’, to many people, means ‘software you don’t have to pay for’—but really it’s so much more than that. It’s a way of thinking and working focused on transparency and collaborating with others. It’s about sharing ideas, plans, and developments for the benefit of the commons. And it’s definitely not just software.

I’ve been following open source closely over the last few years, but as a filmmaker, I never felt like I had skills to contribute to the movement’s development.

But then I realized that everyone, whether librarian, beekeeper, or mechanic, everyone can use the abilities they have in some way to make the world a little better, to help out a cause or an interest they feel is worthwhile. I felt sure that open source could use a filmmaker.

So I’ve started a somewhat insane plan to spread the word about open source, to get others thinking and talking about these ideas of collaboration, transparency, and modification—to show how far open source has come and how far it could go. This will be my Year of Open Source.

For one year I am trying to go as open source as possible, in all aspects of my life—the shoes I wear, the phone I use, even how I get around. I’m not buying any proprietary or traditionally copyrighted products unless all other options are exhausted. I’m looking for and switching to more open, transparent products which are replicable by others, trying to highlight the benefits of treating others as collaborators rather than competitors. I’ll be investigating how the open source philosophy might apply to different areas of life, where it fits well, and where it might not work. Is anybody working on an open source microwave? What would open insurance be like?

With Windows 8 pushing a “touch-first” desktop interface—Microsoft’s words, not ours—and with Valve’s Steam on Linux beginning to bring much-needed games and popular attention to the oft-overlooked operating system, there’s never been a better time to take Linux out for a test drive.

Dipping your toes into the penguin-filled waters of the most popular open-source ecosystem is easy, and you don’t have to commit to switching outright to Linux. You can install it alongside your current Windows system, or even try it without installing anything at all.

Ubuntu is the most popular Linux distribution for desktop and laptop Linux users, so we’ll focus on Ubuntu throughout this guide. For the most part, Ubuntu just plain works. It sports a subtle interface that stays out of your way. It enjoys strong support from software developers (including Valve, since Steam on Linux only officially supports Ubuntu). And you can find tons of information online if you run into problems.

A very open cloud

Businesses will double the amount of data they send across networks in the next few years. In the US, that means greater use of managed IP. Australia, though, like a lot of countries, is heading in the opposite direction.

Cisco’s Virtual Networking Index provides sophisticated forecasts of how we will use networks over the next few years. It estimates that the amount of data transferred by businesses will increase from 6 trillion gigabytes last year to 12 trillion by 2016. Or, if you prefer, 12,051 petabytes.

While Samsung is busy launching the Galaxy Grand and Micromax the A116 Canvas HD, Karbonn has launched the S1 Titanium.

All of them are big screen phablets (phone+tablets) and here is what is common and whats not.

  • Dual Sim
  • 1GB RAM
  • Android 4.1 (Jelly Bean)

Here is the difference, Lets see which one rocks.

Samsung Galaxy Grand Micromax A116 Canvas HD Karbonn S1 Titanium
Display Size 5″ 5″ 4.5″
Display Size 480 x 800, 187 ppi 720 x 1280 pixels, 294 ppi 540 x 960 pixels, 245ppi
CPU Dual Core 1.2 GHz Quad Core 1.2GHz
Quad Core 1.2GHz
Internal Memory 8 GB, expandable to 64 4 GB, expandable to 32 4 GB, expandable to 32
Bluetooth 4.0 2.0 2.0
Primary Camera 8 Megapixel
8 Megapixel 5 Megapixel
Secondary Camera 2 MP VGA VGA
Battery 2100 mAh 2100 mAh 1600 mAh
Estimated Pricing Rs. 21,500 Rs. 14,999 Rs. 10,999

Micromax has the best display, while Karbon has the snappiest Qualcomm Snapdragon processor. The Karbonn is the best value for money. The price difference of Rs. 4000 for Micromax is huge, Expect them to drop prices even before it is launched. If the price of Micromax is dropped to around Rs. 13,000 it would be worthy paying the extra over Karbonn.

Hackable Lego Robot Runs Linux

The Lego Mindstorms EV3 is the first major revamp of the Lego Group’s programmable robot kit since 2006, and the first to run embedded Linux.

Unveiled at the CES Show in Las Vegas yesterday, with the first public demos starting today at the Kids Play Summit at the Venetian Hotel, the $350 robot is built around an upgraded “Intelligent Brick” computer. Lego swapped out the previous microcontroller for a 300MHz ARM9 processor capable of running new Linux-based firmware. As a result, the kids-oriented Mindstorms EV3 offers far more programmability than the NXT series, which was last updated in 2009, says Lego.

Samsung announced an 8 core! yes an 8 core ARM processor which may power the Samsung Galaxy S4

Rather than a single eight-core chip, it has two quad-cores inside – one being a quad-core ARM Cortex A15 and the other a quad-core Cortex A7. The Cortex A15 deals with the tough stuff but passes off the easy tasks to the Cortex A7, or they can both be fired up to really show off. This means it’s strong enough to provide all the power you may need, while at the same time being smart enough to conserve energy when it can. If you’re wondering just how much difference the Exynos 5 Octa and other big.LITTLE chips will make when used in a device, ARM’s CEO Warren East said he expects “twice the performance and half the power consumption” compared to today’s best offerings.

Just when you thought, notebooks were dead and tablets where the future. Samsung has released the Chromebook, which may appeal to a new category of users. This product was the best sell on Amazon for Christmas.

I have been looking at light mobile devices which I can carry instead of a full fledged laptop, and I haven’t found one so far that meets my requirements. I need something which is light weight and has a good battery life. Essentially looking for something which can do Email and take meeting notes with presentations sometimes. Tried a tablet, but missed a proper keyboard. Besides I also wanted it to run Ubuntu, Thunderbird. Lets see if the Chromebook fit the bill ?

Here is what I liked about it.

  • Extremely light weight, 1.1 Kgs or 2.5 pounds
  • Dual Core ARM A15 processor (Samsung Exynos 5 Dual) gives better performance than Intel Atom.
  • 0.8 inch fan-less design
  • HDMI port and HD video playback
  • USB 3.0 and USB 2.0
  • Dual band WiFi
  • SD Card slot
  • 6.5 hours battery life, my Intel based laptop gives 2 hours battery life on a 6 cell battery. This one claims 6 hours with a 2 Cell!
  • 100 GB space for 2 years on Google Drive.
  • Yes you can run Ubuntu, however has some issues.
  • Good value for its price of US$250, 3G is for $330.

What I don’t like.

Has only 16GB storage, although you get 100 GB of google drive free

Hope it had a full fledged OS like Ubuntu, which allows you to run more offline applications. This device is designed in such a way thats it’s always connected.

ChrUbuntu: Ubuntu for Chromebook.

The team behind the Samba file, print, and authentication server suite for Microsoft Windows clients announced the release of Samba version 4 yesterday. This version includes significant new capabilities that offer an open source replacement for many enterprise infrastructure roles currently delivered exclusively by Microsoft software, including acting as a domain controller, providing SMB2.1 protocol support, delivering clustering, and offering a virtual filesystem (VFS) interface. It comes with Coverity security certification and easy upgrade scripts. The release notes include details of all changes.

Notably, this includes the first open source implementation of Microsoft’s Active Directory protocols; Samba previously only offered Windows NT domain controller functions. According to the press release, “Samba 4.0 provides everything needed to serve as an Active Directory Compatible Domain Controller for all versions of Microsoft Windows clients currently supported by Microsoft, including the recently released Windows 8.”

Samba 4 can join existing Active Directory domains and provides all necessary function to host a domain that can be joined by Microsoft Active Directory servers. It provides all the services needed by Microsoft Exchange, as well as opening up the possibility of fully open source alternatives to Exchange such as the OpenChange project.

While ARM is gaining a lot of momentum, the challenge with ARM until now was that every architecture is very different from different vendors and requires a separate kernel and entire OS stack.

With Linux Kernel 3.7, this has changed for the better.

ARM’s problem was that, unlike the x86 architecture, where one Linux kernel could run on almost any PC or server, almost every ARM system required its own customized Linux kernel. Now with 3.7, ARM architectures can use one single vanilla Linux kernel while keeping their special device sauce in device trees.

The end result is that ARM developers will be able to boot and run Linux on their devices and then worry about getting all the extras to work. This will save them, and the Linux kernel developers, a great deal of time and trouble.

Just as good for those ARM architects and programmers who are working on high-end, 64-bit ARM systems, Linux now supports 64-bit ARM processors. 64-bit ARM CPUs won’t ship until in commercial quantities until 2013. When they do arrive though programmers eager to try 64-bit ARM processors on servers will have Linux ready for them.

From PC World.

Ubuntu is a widely popular open-source Linux distribution with eight years of maturity under its belt, and more than 20 million users. Of the roughly 5 percent of desktop OSs accounted for by Linux, at least one survey suggests that about half are Ubuntu. (Windows, meanwhile, accounts for about 84 percent.)

The timing of this latest Ubuntu release couldn’t be better for Windows users faced with the paradigm-busting Windows 8 and the big decision of whether to take the plunge.

Initial uptake of Windows 8 has been unenthusiastic, according to reports, and a full 80 percent of businesses will never adopt it, Gartner predicts. As a result, Microsoft’s big gamble may be desktop Linux’s big opportunity.

So, now that Canonical has thrown down the gauntlet, let’s take a closer look at Ubuntu 12.10 to see how it compares with Windows 8 from a business user’s perspective.

 

Windows 8 Pro (x86) Ubuntu 12.10
License fee $39 to $69 upgrade Free
CPU architectures supported x86, x86-64 x86, x86-64, ARM, PPC
Minimum RAM 1GB, 2GB 512MB
Minimum hard-disk space 20GB 5GB
Concurrent multiuser support No Yes
Workspaces One Two or more
Virtualization Hyper-V KVM
License Not applicable GPL Open Source: Main, Non-GPL: Restricted
Productivity software included None LibreOffice

Apple may be considering switching from Intel processors to ARM chips used in iPhones and iPads for its range of Mac personal computers, said a media report. Published in Bloomberg, the report cited three anonymous sources who said Apple believes that the processors used in its mobile devices will be robust enough to power its line of computers. Intel chips have been used in Mac computers since 2005, while ARM’s processors have been used in iPhones and iPads since their respective launches in 2007 and 2010.
