The Top 7 Best Linux Distributions for You

linuxThere are various approaches to answering this question. The broad answer is: "any of them," but that's not very helpful if you're just looking for a place to start.

The problem is, there never can be one best Linux distribution for everyone, because the needs of each user tend to be unique. Telling someone who's looking for a good introductory distribution to try Gentoo, for instance, would be a mistake because for all its positive qualities, Gentoo is decidedly not a beginner's distro.

All too often, Linux aficionados will tend to list the distributions they like as the best, which is fair, but if they are not aware of their audience, they could suggest something that does not meet that person's needs. Finding a good Linux distribution is like finding a good match in an online dating service: good looks aren't the only quality upon which to judge a Linux distro.

To help users discover the Linux distribution that's best for them, this resource will definitively list the best candidates for the various types of Linux users to try. The use-case categories will be:

  1. Best Desktop Distribution

  2. Best Laptop Distribution

  3. Best Enterprise Desktop

  4. Best Enterprise Server

  5. Best LiveCD

  6. Best Security-Enhanced Distribution

  7. Best Multimedia Distribution

Once you find the best Linux distribution for your needs, you can visit our Linux Migration Guides to assist you in installing and using the one you'd like to try.
Best Linux Desktop Distribution

There are a lot of Linux distributions that have the primary focus of becoming the next best desktop replacement for Windows or OS X. Of all the categories in this list, this is the most sought-after, and contentious, group of distros.

While it would be ideal to include many distributions on this list, the reality is that there really needs to be just one "best" Linux distribution. For early 2010, that distro has to be Canonical's Ubuntu.


Ubuntu edges out its closest contenders, Fedora and openSUSE, because its development team is constantly focused on the end-user experience. Canonical and the Ubuntu community have spent a lot of time and resources on bringing ease-of-use tools to this distribution, particularly in the area of installing Ubuntu and installing applications within Ubuntu.

In addition, Ubuntu's level of support for its desktop products is highly superior, which is important in this class of distributions since it is the most likely to contain users new to Linux. Both the official and unofficial Ubuntu documentation is robust and searchable, a big plus.
Best Linux Laptop Distribution

Laptop distributions almost fall into the same category as desktop users, but there are a number of key differences that make the criteria for evaluating a good laptop distribution important. Power management, docking tools, and wireless ease-of-use are critical to users on the go, as is having a distro that meets those needs.

Right now, the best laptop distribution is openSUSE, one of the lead contenders for the desktop honors. On the laptop, openSUSE shines with great connectivity tools, such as an easy-to-use networking toolset that not only handles WiFi connectivity, but also CDMA/cellular modem connections.

Create and Run Virtual Machines With virt-manager

Virtual machines make administrative live so much easier. Not only can you test out new operating systems (without damaging your currently running OS), you can test new features, you can sandbox your web sites, you can develop new security models...the list goes on and on. But just as there are numerous reasons why you would want to run a virtual machine, there are numerous ways to create a virtual machine.

You have already seen my articles on virtualization, here on If not check out "Virtualbox offers simple, easy to use virtual solutions" and "Installing Virtual Machines in VMWare". Another virtual machine solution is virt-manager. The virt-manager tool is a GUI tool that can use either QEMU or KVM as its hypervisor. Unlike VirtualBox or VMWare, there are a few tools that have to be installed, but more importantly, your CPU must be able to support hardware virtualization. So before we get into the installation of any of the tools (and the setting up of your virtual machines) it's best to run a simple test to find out if your hardware will support this technology.

Please get the information on, It was posting about virtualization that can help us and it's article is friendly and easy to be applied.


How Chrome OS and Clouds Can Alter Your Company's View of Computing

Chrome OS is Google's attempt to create a fast, simple, and secure netbook. The popularity of Chrome OS netbooks depends on a large number of applications becoming Web-based and on the emergence of cloud computing as a way to reduce the cost of maintaining and managing data centers. We believe that Chrome OS will impact your data center strategy and change the way you view desktop computing.

Today, many workers carry expensive, heavy, Windows notebooks loaded with the applications they use and their data. A few carry netbooks to complement their bigger notebooks because netbooks are small, convenient to carry, and provide very fast access to the Web. And almost all of us that work carries a smartphone such as the iPhone or Motorola Droid that provides us with email, thousands of Web-based applications, and very fast access to the Web. The popularity of smartphones for accessing the Web and running Web-based applications are proof that the way we view desktops is changing rapidly from the 1980's view of desktops fostered by Microsoft.

Given some applications that workers need are not yet Web-based, many of us still need our notebooks. But if you look at the types of activities that you do each day, you will discover that many of them involve accessing the Web. Many people write and edit documents, search for information on the web, create/update web sites using various tools, write programs using various scripting languages, create demos, create presentations and spreadsheets, read/create lots of email, manage their calendar, or use applications such as Photoshop, etc.

Many of the activities that you do each day involve accessing the Web. You don't need a notebook for that. Because most people are using Windows notebooks (95 percent of the over one billions PCs are running Windows), you are probably using Microsoft Office, which is not Web-based (yet!) to write documents and create presentations. However, there are other productivity tools that are Web-based. The problem is that the formats they use are not always compatible with Microsoft Office formatting. Fortunately, many application developers and ISVs understand that Web-based applications are the future and as a result are creating Web-based versions of their applications. Cloud providers and some ISVs such as IBM are making their applications available on clouds, allowing you to pay usage fees versus spending large sums of money on licensing contracts.

IT managers are always looking to reduce data center costs and increase business agility. They have had some early successes with server virtualization, but server virtualization is mostly a manual process requiring much system administration. It lacks the automation capabilities that will become visible with clouds. IT managers must now begin thinking about using clouds (internal and/or public) and turning applications into Web-based applications. CFO/CIOs also want to lower the cost of computing in their companies. They would like nothing more than to reduce the costs of purchasing expensive notebooks, replacing hard drives and batteries, and purchasing software for almost all employees and hiring employees to help workers keep their notebook software up-to-date.

How will Chrome OS (netbooks) impact your data center strategy? First, a bit about Chrome OS. There have been many discussions around Chrome OS replacing Windows even though Google has made it clear that Chrome OS is not intended to replace Windows. But with the announcement of Chrome OS, Google is saying that desktop environments like Windows are obsolete. Google is also saying that many people don't need Microsoft Office and many of the other Windows applications.

Google is trying to shift you toward a vision of cloud computing in which applications are not stored on your hard drive, but rather in clouds accessed through a Web browser. Millions and millions of users are already using clouds today even if they don't realize it. In the future, you will be accessing the Web and running Web applications from various types of devices using browsers versus carrying around notebooks with big hard drives loaded with applications.

Chrome OS is not intended to be a sophisticated operating system. It is just the Chrome browser optimized to run on a slimed down Linux kernel. Chrome OS applications are Web-based, meaning there will be no native applications stored on a hard drive, and all of the data is in the cloud. You will not be installing or maintaining any software. Chrome OS will not be downloadable to existing PCs. It will come pre-installed on new, netbook-like devices similar to small computers with a screen, touchpad, and a full size keyboard. They won't have hard drives; instead, they will have solid-state drives.

The goals for Chrome OS are security, simplicity, and speed. Chrome OS eliminates much of the conventional startup process. There is no searching for drives and other devices and the starting up of background applications and services like we find on Mac and Windows personal computers. It automatically updates itself with available updates/patches delivered automatically over the Web. User data is stored encrypted and all data is synched to the cloud. Chrome OS follows Google's successful debut of Android, which is also hosted on a Linux kernel. Android is being used in millions of smart phones such as the Motorola Droid.

How will you use Chrome OS netbooks? You will write papers, create spreadsheets, listen to music, etc. using Web-based applications. Chrome OS supports Google's services, but third party Web-based applications are also expected to be developed in the same manner as tens of thousand Linux applications have been developed. In addition, many applications that are not currently Web-based will, over time, become Web-based. One question that some users are asking about Chrome OS is “What do I do when the cloud is down?” Answer: “What do you do when your Windows notebook is down and your applications and data are stored on it?”

How will the advent of Chrome OS along with clouds alter your company's view of computing? The introduction of cloud computing into your data center in the form of public clouds and/or internal clouds facilitates the use of Chrome OS netbooks, both internally and externally. As many of the applications that you use are made available via clouds, the need for expensive notebooks with applications stored on hard drives will drop. To get the maximum benefit from Chrome OS netbooks in a cloud-based data center, ISVs and custom applications need to be made Web-available.

The security, simplicity, speed, and low cost of Chrome OS netbooks can drive your company to expedite the use of cloud computing in the data center. The cost savings from the use of Chrome OS netbooks versus expensive desktops and notebooks, and the cost savings from the use of clouds are large. Chrome OS is faster, safer, and cheaper than Windows. Chrome OS netbooks don't require monthly maintenance to keep them running, and they will also eliminate most of the people costs associated with helping users keep their notebook operating systems and applications updated/upgraded. Because applications are browser based and not stored on your notebook, you do not have to worry about upgrading to the next release of software. We envision the time when your work computer and your home computer are the same: Chrome OS netbooks.

As an IT manager, you should pay little attention to Microsoft's comments around Chrome OS. Microsoft's Ballmer is baffled by what is going on at Google indicating that he does not know why anyone needs two client operating systems. How many does Microsoft have? The reason Microsoft is taking shots at Chrome OS is that Chrome OS will make it very difficult for Microsoft to raise the prices on its Windows 7-based netbooks. This is something Microsoft decided to do after its low end Windows PCs and notebooks market was cannibalized by cheap netbooks powered by a low cost version of Windows XP. Learn more


Smartbook Playing Field Wide Open for Linux

There's been a lot of technology predictions for the upcoming year, with Linux playing a big part in the future direction of tech. Fortunately, we won't have to wait long to see how some of those predictions will play out: it's just a mere three more days until the start of the Consumer Electronics Show (CES) in Las Vegas.

Even before the 2010 CES show starts on January 7, as early as tomorrow, Jan. 5, Google is expected to formally announce their upcoming smartphone, the Nexus One. Nexus One, rumored to be based on HTC's Passion device, is expected to be sold with complete Google branding and a pure Android platform. More importantly, Google may be planning to sell the device as an unlocked GSM phone, which means anyone can buy the device and then get a calling plan separately with any carrier they want with a compatible GSM network.

Beyond that, as if that would not be big enough news, look for more Android-based offerings--from phones to tablet devices--showing up at the CES event proper.

In the meantime, a new buzzword may be dominant at the Vegas electronics show: smartbooks. First seen from Sharp in November with their NetWalker PC-71 device, these handhelds are, as you might expect from the name, somewhere between a smartphone and a netbook. These ultra-small devices are always connected to the Internet via 3G cellular networks and will provide productivity apps, via their Linux platforms, for users.

Even though this class of device was out last fall, the big reveals will be staged at CES later this week, from Qualcomm and Sharp, to name two manufacturers. With ARM-based chips and Linux as the OS reducing the costs of these devices, analysts are predicting that if smartbooks are accepted by consumers, smartbooks could become real profit generators for hardware makers.

Curiously, there won't be much competition for Linux-based mobile offerings at CES. Apple isn't expected to announce its rumored tablet device until January 26, and Windows Mobile continues to struggle with declining market share.

This decline in Windows Mobile is interesting, because it seems to belie one of the main arguments against Linux on mobile devices: that Linux devices are limited in their functionality by their lack of applications.

This argument was most recently framed in a Wall Street Journal article about the rise of smartbooks at CES, which felt the need to highlight a caveat about these devices: "But smartbooks running Linux or its offshoots, such as Google Inc.'s Android, won't run applications like Microsoft Word or Apple's iTunes. Early netbooks that ran Linux ran into customer resistance and were quickly replaced with Windows-based models."

Which is followed up by this rather expected comment: "'Customers will likely continue to choose Windows netbook PCs over Linux smartbooks for these same reasons,' predicts Ben Rudolph, a Microsoft senior manager for Windows." Learn more

Get One, Give One Shares Benefits of LF Membership

As you get your holiday shopping done, you may find yourself wondering what you can get for the student in your life. Thanks to a new Linux Foundation program, if you sign up for an individual membership with the Linux Foundation, the Linux Foundation will donate a free one-year student membership either to a student you know, or students who are seeking a sponsored membership.

This is a great deal, because it allows new members a way to share the benefits of the Linux Foundation to students who might not otherwise be able to sign up for Linux Foundation membership.

Here's how the new program works: for every new individual member who joins the Linux Foundation before January 31, 2010, the Linux Foundation will give a free membership to a student for one year. Students who are interested in obtaining a sponsored membership can sign up on a waiting list and will be sponsored on a first-come, first-serve basis.

When they join the Linux Foundation, new individual members can elect to either sponsor a student on the waiting list or can request the membership be given to a friend or family member. To sponsor a specific student, new members should list the student's name and email address in the order comments on the checkout page.

Any student, whether specified or on the waiting list, will be required to show proof of student status in the form of a valid student ID.


Canonical’s opportunity to simplify Ubuntu

Ubuntu has led the Linux community’s efforts to improve on form, not simply function, and thereby make the Linux experience as good or better than Mac OS X in terms of usability. Mark Shuttleworth, founder and CEO of Canonical, the company set up to shepherd development and commercialization of Ubuntu, is the heart of that effort.
As announced on Thursday, however, Shuttleworth is resigning as Canonical CEO to focus on improving the Ubuntu user experience:

From March next year, I’ll focus my Canonical energy on product design, partnerships and customers. Those are the areas that I enjoy most and also the areas where I can best shape the impact we have on open source and the technology market.

Is this good or bad for Ubuntu? And what about Canonical?

Canonical is reportedly doing $30 million per year in sales, and is working on some significant projects that may establish it as the de facto Linux distribution for Netbooks, if it isn’t already. (Ubuntu is arguably the community choice for personal computers.)

Even so, Linux still has a long way to go to match the user experience of Mac OS X, or even Windows. Shuttleworth has given me a sneak peak of his vision for where Ubuntu can go from a UI perspective.

I was blown away. This is a man who “gets it.”

Even so, he and the Ubuntu community still have a ways to go to match Microsoft or Apple in user experience, and certainly in market share. To get there, Ubuntu needs Canonical, and Canonical needs Shuttleworth fixated on improving Ubuntu’s user experience.

When I asked what his resignation as CEO means for Ubuntu, and his involvement with it, Shuttleworth responded:

I don’t expect to be less visible, just have stronger management for the business units.
