A perfect storm is converging on data centers worldwide. Like any hurricane, it’s driven by heat energy: in this case the waste heat from ever-denser racks of blade servers.  Every watt of IT power can require as much as 2.5 watts for cooling, and the combined business and environmental impact of the energy needed is driving interest in the green data center.

The Clarkdale Review: Intel’s Core i5 661, i3 540 & i3 530

I swear this is the longest it’s taken for an Intel architecture to penetrate the market. We first met Nehalem on November 3rd, 2008. It came to us as a high end quad-core processor and took a full year to make it to more affordable motherboards in the form of Lynnfield. Even with P55 motherboard prices down at the magical $99 marker, Intel relinquished control of the $100 – $200 CPU market without a Nehalem to compete down there. Instead we were left with a choice between Penryn, the update to Intel’s 2006 Conroe architecture, or Phenom II, AMD’s low-cost Nehalem competitor. The choice was simple.

GIGABYTE GeForce GT-240 HDMI Video Card

As enthusiasts, we’re always interested in the latest monster video cards: the expensive, high-end products that blast through benchmarks fand play all your games with buttery-smooth frame rates at the highest resolutions with all the settings maxed out- and sucking a not inconsiderable amount of electricity while doing so! But these products represent only a tiny fraction of the number of video cards sold; the low-to-mid-end cards comprise the bulk of the market. Besides, a GTX285 or Radeon 5870 isn’t the ideal solution for every situation: considerations from a limited budget to building a small, quiet system come into play. Read more…

Goodbye to the GIMP

It’s a sad time for Ubuntu users. Canonical has announced that it is removing the GNU Image Manipulation Program, aka GIMP, from the default Ubuntu installation routine.

Canonical hosted its biannual Ubuntu Developer Summit (UDS) last week in Dallas, Texas. I was one of many open source software developers who attended the event and participated in the collaborative process of planning Ubuntu 10.04, the next version of the popular Linux distribution. An important part of the 10.04 roadmap that emerged during UDS is a tentative plan to remove the GIMP, the GNU Image Manipulation Tool, from the default Ubuntu installation. Although this decision is viewed by some as controversial, the reasoning behind it is valid.
