And the best Linux desktop distro of all is…

hen it comes to Linux, there is no one size fits all answer. But, unlike other desktop operating systems, Linux doesn’t try to squeeze you into a system’s that’s too large or too small. Instead, Linux offers a wide variety of distributions and one of them is likely be the right one for you.

Linux, you see, is a family of operating systems. They share the same father, but each distribution has its own personality and its own audience. For example, if you really wanted to, you can have a Linux distribution that looks and act like Windows XP, but which underneath its Microsoft-like surface is actually running Ubuntu Linux. Or, if that doesn’t strike your fancy, you can always make the popular Ubuntu distribution into a Mac OS X look-alike.

Better still, you can find a Linux that will do what you want it to do. After all, despite silly tales of how you have to be some kind of technical wizard who chants “awk, grep, sed” at a shell command prompt to use Linux, anyone can run Linux these days. The default Linux desktop KDE or GNOME graphical interfaces may not look quite like the ones you’re used to but they’re every bit as easy to use and as powerful. Yes, once in a blue moon you may need to modify a configuration file by hand, but you’ll need to do it no more often than a Windows user has to do the exact same kind of thing with the regedit command.

The real question isn’t, “Can I run Linux?” It’s “which Linux is best for me?” Here’s my guide to help you find the right one for you.

There’s No Reason to Wait for Windows 7 SP1

Waiting for Windows 7 SP1 before updating? Why? It’s ready to go today.

Historically, adopting the first version of any major Microsoft software release has been, well, a mistake. Sometimes, as with Windows NT, it took several iterations — until NT4 SP3 — before the operating system really worked well. And, with the far more recent Windows Vista fiasco in mind, no one could blame you for not aggressively looking into shifting your business desktops from Windows XP to Windows 7. But, more than six months after Windows 7 was released to manufacturing, it’s become clear that there’s no reason to wait for SP1 before moving up to Windows 7.

I’ve had little love for Windows over the years. But this time, while I can still give you chapter and verse on why a Linux desktop is worth considering, I have to say that I’m impressed by Windows 7. More to the point, after over a year of working with Windows 7 from late beta until now, I’ve found it more than stable enough to consider as a Windows XP replacement today.

People’s usual reasons for holding off on an upgrade until SP1 is fear that an early Windows version will break underneath them. That’s not the case here.

I have been beating the heck out of Windows 7 on a variety of systems and to coin a phrase, “It just works.” Along the way I have also run on the OS mainstream business software such as Microsoft Office, OpenOffice, QuickBooks, and dozens of other programs, and I’ve yet to find a need for Windows 7?s built-in XP virtualization. At the same time, I’ve also found that most everyday business peripherals such as printers, scanners, and the like also have no trouble with Windows 7.

This isn’t to say that you should just run out buy a few thousand Windows 7 licenses and start your conversion process tomorrow. That would be the height of folly. What I am saying is that you don’t need to wait until SP1 appears before starting a migration.

So why should you make the move? For me, the real corporate IT win isn’t in Windows 7 by itself. If you were to ask me to name one compelling reason to move from Windows XP SP3 to Windows 7, I couldn’t give you one.

But if you put Windows 7 together with Windows Server 2008 R2, then I think you get something that is well worth an enterprise’s time and money. Primarily, what I like is their combination of high-end networking services.

I’m not talking about cute — but not game-changing — services such as location-aware printing that makes sure your laptop users always and automatically use the right printer no matter where they are. No, it’s features such as BranchCache; DirectAccess; Secure Remote Connect; URL-based Quality of Service; and improved IPv6 support.

The net effect of all these services is to greatly improve your network’s overall performance. BranchCache makes it much easier for your branch offices to stay in sync with the central office’s servers. DirectAccess, Secure Remote Connect and IPv6 team up in a variety of ways to maximize the utility of your Internet connection, and URL-based Quality of Service helps make sure that your important network traffic gets the priority it deserves without requiring constant network administration tuning.

These advances may not mean much for a small company, but when you’re looking at hundreds to hundreds of thousands of PCs, all those network speed boosts add up to a considerable savings both for network management and overall worker performance.

Still, you should also keep in mind that, like it or lump it, you’re probably going to need to buy new computers when you move from Windows XP to Windows 7. While it’s relatively easy to upgrade from Windows Vista to Windows 7, it’s far more difficult to move from Windows XP to Windows 7. That said, your Windows XP systems aren’t getting any younger and their maintenance costs will only get higher.

It’s also a sad, but true, fact that some high-end equipment isn’t supported by Windows 7 or by its vendors. For example, Intel’s 82801ER SATA RAID disk controller, which was used in high-end Xeon workstations, doesn’t work well with Windows 7.

So, if you do elect to move to Windows 7 sooner rather than later, you should be certain to do your due diligence with both software and hardware. This means more than just checking Microsoft’s Windows Compatibility Center. You need to do hands-on testing. I strongly suspect that, in the end, when it comes to hardware you’ll find it cheaper to buy new computers than it will be to retrofit your older XP systems with Windows 7.

In my experience, it’s often easier and less expensive to swap out machines than it is to upgrade them no matter what the operating system. With PCs at near historic lows in terms of price for CPU power, RAM, and disk space, now may actually be a good time to move to Windows 7.

Yes, I know, I know. Budgets are tight all over. On the other hand, since Windows 7 is proving to be remarkably stable and work-ready already why not upgrade now and reap the benefits from Windows 7?s more advanced networking features today? After all, sooner or later, probably sooner, you’re going to need to update your desktop operating systems. Better to upgrade now than before broken systems force your hands into an ad hoc migration situation.

Chrome 4: King of the Web browser hill?

Firefox 3.6 has just come out and it’s great. There’s only one problem. Google has released the new version of Chrome, version 4, and it’s even better.

This new version retains its speed lead over other browsers. I tested it on one of my Dell 530S desktop PCs. This PC is powered by a 2.2GHz Intel Pentium E2200 dual-core processor with an 800MHz front-side bus. It has 4GB of RAM, a 500GB SATA (Serial ATA) drive, and an Integrated Intel 3100 GMA (Graphics Media Accelerator) chipset and was running Windows XP SP3. On this machine, Chrome ripped by Firefox 3.6 on the SunSpider JavaScript benchmark test with a mark of 530.8 milliseconds compared to Firefox 3.6’s 1007.0 milliseconds.

While faster than Firefox, Chrome 4 isn’t a great deal faster than Chrome 3.x. On the same machine, my older copy of Chrome came in with a time of 553.0 milliseconds. I was unable to test this production version of Chrome on Linux or a Mac because those versions are still in beta.

Speed, though, isn’t the real news in this latest version of Chrome. This time around it’s the addition of features that demands your attention.

Record-setting Linux

I know the value of Pi, the irrational number you get when you divide the circumference of a circle by its diameter, as far as 3.14159 and after that I’m clueless. Recently, though, French software engineer, Fabrice Bellard, calculated the value of Pi out o 2.7 trillion numbers… with a souped-up but otherwise ordinary home PC running Red Hat’s Fedora Linux.

Bellard, best known for being the founding developer of FFMpeg, the highly respected audio/video program for converting music and movies from one format to another, took on Pi not because he was “especially interested in the digits of Pi, ” but because he was interested “in the various algorithms involved to do arbitrary-precision arithmetic. Optimizing these algorithms to get good performance is a difficult programming challenge.” You can say that again.

To pull this off, Bellard used a PC running an 2.93 GHz 64-bit Intel Core i7 CPU with just over 6GBs of RAM. The only thing really extraordinary about his record-setting PC was that he used 7.5 TB (TeraBytes) of disk storage. This consisted of five Seagate Barracuda 7200.11 1.5 TB hard disks. These are high-performance drives with 3 Gbps (Gigabit per second) SATA (Serial ATA) interfaces.

The IE Fix is in

I still think that the safest thing you can do about your Web browsing habits is to switch from IE (Internet Explorer) to Firefox or some other browser. But, if you’re wedded to IE 7 or 8 — please, please stop using IE 6–Microsoft has made a fix available for all versions of IE. If you’re reading this and you haven’t upgraded your copy of IE yet, do yourself a favor, do it now. I’ll wait for you.

OK, using updated IE or some other browser now? Good. Now, for the bad news, it turns out that Microsoft knew about this critical bug since last August!.

Some people are making excuses for Microsoft that five months isn’t too long for them to fix this, and seven other serious IE bugs. Please. Give me a break. Serious security bugs are found and fixed in open-source software in days or weeks. Why should Microsoft get a free pass?

Google’s Chrome OS: Tomorrow’s Desktop Today?

Sometime in 2010, Google will release Chrome OS, its take on a netbook operating system. It will be far more than just that though. It’s an entirely new take on the desktop operating system. While a final version is still months away from release there’s already enough of Chrome available that we can begin to see what it’s going to look like.

or starters, Chrome OS is Linux. To be exact, it owes a lot of its genes to Ubuntu. But, that’s all under the surface. You won’t need to know a shell command from the GNOME desktop to use it. As a matter of fact, you won’t need to know anything about the traditional Linux desktops — KDE or GNOME — either. Chrome OS’s interface is Google’s Chrome browser. If you can use a Web browser, you’ll be able to use Chrome OS.

That’s not the case now. Today, you have two choices if you want to try Chrome OS. The first is to build it yourself using Google’s instructions. While this is trivial enough for an expert Linux user, it’s not for anyone else. The easier way to give it a try is to visit Chrome OS Blog, a fan site for Chrome OS that features frequent builds of Chrome OS that you can either run off a USB stick or as a virtual machine using Sun’s VirtualBox.

Either way, you should keep in mind that you’re working with a sketch of an operating system. This is no way, shape, or form an operating system that’s ready for prime-time yet. Between it, and recent public comments from Matthew Papakipos, Chrome OS’ engineering director, you can see where Google is heading with its netbook operating system.
