Windows vs. Linux vs. OS X: CIO John Halamka Tests Ubuntu

As part of his ongoing effort to find a secure, stable, user-friendly alternative to the Windows desktop operating system, CareGroup CIO John Halamka got to know Ubuntu.


Last summer, CareGroup CIO John Halamka began looking for a viable alternative to the Microsoft Windows desktop operating system. After 16 years using Windows, he had enough of its instability and the countless updates that automatically installed themselves on his computer—often at inopportune times, like when he was in the middle of a presentation. As CIO of a health-care organization and affiliated medical school with 40,000 employees and 9 million patient records, Halamka has to be sure that the computers in the hospital, its administrative offices and medical school are secure, stable and easy to use.

Windows vs. Linux vs. OS X: CIO John Halamka Tests SUSE

With Linux, Google and Apple beginning to threaten Microsoft’s desktop dominance, the time was right for Halamka to investigate the options. Last July, he quit Windows cold turkey and used a MacBook running OS X as his sole computing machine to see how it stacked up against Windows. In August, he worked with two Linux distributions: Red Hat Enterprise Linux and Fedora Core. The following month, he returned to Windows XP to more clearly see how its stability, reliability, security and ease of use compared with the other operating systems. reported on Halamka’s experiences using each operating system and about their future in his enterprise in Windows vs. Linux vs. OS X.

Since that story was published, Halamka has also investigated two other Linux distributions: enterprise-ready SUSE and consumer-friendly Ubuntu. He used each distribution as his exclusive computing platform for a month, as he did with Mac OS X, Red Hat Enterprise Linux, Fedora and Windows XP.

Halamka’s month with Ubuntu concludes his formal operating system evaluations. What follows are the details of his experience running Ubuntu and his plans for his company’s enterprise desktops and laptops moving forward. Will he finally replace Windows forever with OS X or Linux? You’ll see...

Configuration: Dell D420 subnotebook running Ubuntu Feisty Fawn (release 7.04). The OS comes with the OpenOffice productivity suite, which consists of word processing, spreadsheet and presentation programs, the Firefox Web browser, Evolution 2.10.1 for e-mail, the Gimp image editor, F-spot photo manager, the Rhythmbox music and movie player, and a vast library of free and proprietary software. Halamka added Adobe Acrobat, Flash, Java, RealPlayer and multimedia codecs to his computer from the library.


Eight Reasons NOT to Use Linux in the Enterprise

Seven Financial Reasons to Use Linux in the Enterprise

Ubuntu is a consumer-friendly distribution of Linux based on the Debian operating system. The major difference between Debian and Ubuntu is that Debian adheres to a strict philosophy around free software—not free as in zero cost, but in the sense that users are “free” to modify and redistribute the software. Debian discourages the use of non-free, proprietary and copyrighted software by making users install such programs on their own. For example, if you want to install Adobe’s Acrobat PDF reader on a computer running Debian, you have to find, install and configure the software yourself.

Ubuntu, by contrast, gives users access to a broader array of software, including proprietary programs, and makes it easy for users to install those programs. To install Adobe Acrobat on a computer running Ubuntu, you simply select it from a software library that comes with Ubuntu, and the operating system installs it for you.

Debian’s stringent politics extend to the Firefox Web browser, too. Even though Firefox is open source, the browser isn’t bundled with Debian because the Firefox logo is trademarked. (Instead, Debian computers come with a browser called Ice Weasel; it’s exactly the same as Firefox except it has a different logo.)

Although Halamka supports the notion of free software—at least in theory—he knows Debian is not the right thing for his enterprise. He says:

“At the risk of sounding like a software atheist, I really care about getting my work done via a reliable, stable operating system and not about the philosophical subtleties of Firefox vs. Ice Weasel artwork. This is likely one reason that corporate CIOs are wary of Linux on the desktop: They have mission-critical operations to run, and worrying about which icon is used to launch a browser is about as relevant as arguing how many angels can dance on the head of a pin.”

<< Introduction    |   What He Liked >>

What he liked:

In Ubuntu, Halamka found a well supported, intuitive operating system that offered great flexibility and a solid update management system. Though he went into the evaluation with some concern that Ubuntu would prove too consumer-oriented and wouldn’t be robust enough for his rigorous needs as a knowledge worker, the OS met all of his criteria and exceeded his expectations.

“It may not have all the enterprise management tools that SUSE has, but Ubuntu is not just a play-games-and-listen-to-music operating system,” says Halamka.

Ubuntu is an African word that awkwardly translates to, “I am what I am because of who we all are.” Mark Shuttleworth, founder of the Ubuntu project, was born and raised in South Africa.

Like Apple developers, Ubuntu software engineers focus heavily on usability. The result is an intuitive graphical user interface that features just three menu offerings: applications, which is where you find all your software programs; places, which opens your hard drive and any peripheral drive you may attach; and system, which consists of all the utilities you need to maintain your computer system, including libraries of available applications. Ubuntu looks and feels more like a Mac, and Halamka certainly grew fond of his MacBook.

SUSE, by contrast, looks and feels more like Windows. It features a Start button, which, when you push it, shows the applications you used most recently and a control panel. Halamka preferred Ubuntu’s user interface to SUSE’s because it was simpler and more straightforward, but he notes that SUSE might be more appropriate for workers used to Windows.

Halamka was also impressed with Ubuntu’s Synaptic Package Management System, a graphical tool that allows users to search from three different catalogs—or libraries—of software. Ubuntu automatically installs any software you select.

The OS is particularly cognizant of the distinction between proprietary and open-source software. An Ubuntu menu selection called Restricted Driver Manager lists the non-free software running on a user’s computer and provides management tools for specific proprietary applications that do not adhere to the free-software principles. And if you choose proprietary software from one of the catalogs, the OS notifies you that you’re doing so.

For example, when Halamka installed the Intel PRO/Wireless 3945 ABG wireless card, the Ubuntu installer told him that the wireless card required a non-free Intel driver and asked him if it was OK to install it. He clicked the Yes button, the computer installed it, and his wireless card began working immediately. The reason his computer prompted him—and the reason he might not have wanted to install it—is that even though the software may not cost anything to install, the intellectual property behind it may be proprietary so the Ubuntu project can’t automatically bundle them with the operating system software. Also, the Ubuntu community doesn’t support proprietary software. (For more information on what it takes to install Ubuntu and extra applications, see 10 Steps for Installing Ubuntu.)

Halamka preferred Ubuntu’s Synaptic Package Manager and Update Manager to SUSE’s Yast approach to system preferences and administration for a variety of reasons. For one thing, he says, Yast isn’t as easy to use as Synaptic. “Yast is supposed to search Novell's preconfigured repositories, but it did not seem to work for me,” says Halamka. “I received update notifications on existing packages but did not find the same rich application repository that I found with Ubuntu.”

To be fair, the CIO adds, Yast’s functionality may be more limited because SUSE is designed for controlled, corporate implementations, in which it’s important to have a more locked-down computing environment.

What’s more, when Halamka wanted to configure software on his Lenovo laptop running SUSE, he didn’t always find the tools in Yast; sometimes they were filed under the Utilities menu. In Ubuntu, all systems tools are in one menu, he says.

Ubuntu’s update manager also allowed Halamka to run older software versions without constantly pestering him to upgrade to the most recent version. While using SUSE, he had to downgrade his version of Evolution to apply a Novell patch that would speed the application’s startup time. Unfortunately, whenever he launched the older version of Evolution, he was always prompted to upgrade to the most recent version. Halamka found these recurring prompts, which he couldn’t disable, annoying.

Finally, when Halamka removed programs from his Dell, Ubuntu figured out all the dependencies between applications and automatically removed other, shared programs that were no longer necessary. “I never saw that on SUSE,” he says.

In addition to Ubuntu’s user-friendly interface and management tools, Halamka was taken with the “amazing amount of support” the community provides online. Desktop and laptop support is a key part of Ubuntu’s mission.

Halamka had noted the stability of some operating systems, such as Mac OS X and SUSE. They worked so well, he said, because they were configured to the hardware on which they were running. The not-so-great experiences he had with Red Hat Enterprise Linux and Fedora could in part be chalked up to the fact that the operating systems hadn’t been configured to the Lenovo laptop he was using at the time.

Even though Ubuntu wasn’t preconfigured specifically for his Dell laptop, Halamka had the same smooth user experience with Ubuntu that he had with OSes that were preconfigured to hardware. He experienced no lockups or crashes when he “woke” his computer from sleep mode, as he had with Red Hat Enterprise Linux and Fedora. His computer also reconnected to wireless networks without a hitch on waking from hibernation, which was an initial problem with SUSE. He had no problems using his laptop or any of the applications on it, except for Evolution, during his month with Ubuntu and even while he traveled in Japan.

All in all, Halamka gave Ubuntu a big thumbs-up for its user interface, management tools and support. He felt the Ubuntu community had done a bang-up job developing an OS that was easy to install and required little configuration.

<< Configuration    |   What He Disliked >>

What he disliked:

The two major problems Halamka experienced with Ubuntu were the same ones he encountered with SUSE: The operating system doesn’t support CareGroup’s secure EAP-FAST wireless network, and Evolution, his e-mail client, took six minutes to start up.

With regard to Evolution e-mail, SUSE actually has an advantage over Ubuntu, at least for now. Novell’s SUSE engineers created a patch for Evolution that makes the application start more quickly, in about 20 seconds. But since that patch hasn’t been worked into the current version of Evolution on Ubuntu, Halamka had to use the standard distribution of Evolution. Halamka expects that Novell will contribute the code it developed for Evolution to the open-source community, whereupon it will probably be integrated into forthcoming versions of Ubuntu, which are released every six months.

The only other problem Halamka ran into was with MIDI music files. Ubuntu doesn’t natively support them, he says, so when he tried opening one, the OS prompted him to choose from a list of packages available to play the file. He selected Kmid, and Ubuntu automatically installed the program. Yet, he still couldn’t play the file. He searched the Web for an answer and found conflicting approaches to the problem, each of which, he says, required many command line operations. After an hour of troubleshooting, he gave up and removed all the programs he had installed in the process, including Kmid, which was the easiest part of the whole tedious process, thanks to Synaptic. “I’ll play MIDI files on my Mac, which just works,” he says.
