2009 Year of The Linux Desktop – Linux to Ship More Desktops than Windows

Jim Zemlin is executive director of the Linux Foundation has posted some interesting information and very bold prediction about Linux desktop:

For those that decry the constant prediction of the "year of the Linux desktop". I am happy to say that next year Linux may actually ship on more desktops than Windows or the Mac. That is right, I said next year. What is driving this? Two words: fast boot.

Download of The Day: CRON-O-Meter Open Source Dieting Software

CRON-O-Meter is free, open source, and cross-platform (Windows, Linux and Mac OS X) dieting software written in Java. It is a fully featured nutrition and biomarker tracking tool. Designed for practitioners of Caloric Restriction (CRON) Diets.

From the project site:

CR (Calorie Reduced) diets require a lot of information to perform optimally. In order to restrict caloric intake, but remain healthy, users of the diet must track their vitamin, mineral, and protein intakes with great care.

We aim to provide a complete solution to the CR dieter. Current open-source diet-tracking applications fall short in some vital respects. Either they are not detailed enough, or they suffer from critical usability flaws. We believe that a diet tracker must be effortless to operate for the activity for which it will be used most of the time, keeping track of the foods eaten in a particular meal.

To this end, we are developing CRON-O-Meter, an application that will take into account good usability design and dense functionality. It will provide diet advice, track consumption and exercise, and generally assist in all aspects of a CR diet.

Gartner Report: MS-Windows Is Collapsing

Wow, the researchers warn that Windows is collapsing and Linux / OS X replacing Windows:

Calling the situation "untenable" and describing Windows as "collapsing," a pair of Gartner analysts this week said Microsoft must make radical changes to the operating system or risk becoming a has-been.

In a presentation at a Gartner-sponsored conference in Las Vegas, analysts Michael Silver and Neil MacDonald said Microsoft has not responded to the market, is overburdened by nearly two decades of legacy code and decisions and faces serious competition on a whole host of fronts that will make Windows moot unless the Redmond, Washington developer acts.

This article explains why Windows is broken:

Two Gartner analysts said the words that enterprises dread, and that will move alternate operating system proponents to tears of joy: "Windows as we know it needs to be replaced." Microsoft's operating system (OS) development times are too long and they deliver limited innovation; their OSs provide an inconsistent experience between platforms, with significant compatibility issues; and other vendors are out-innovating Microsoft . That gives enterprises unpredictable releases with limited value, management costs that are too high, and new releases that break too many apps and take too long to test and adopt. With end users bringing their own software solutions into the office...well, it's just a heck of a sad story for Microsoft.
