The reduced instruction set computer, or RISC, is a microprocessor CPU design philosophy that favors a simpler set of instructions that all take about the same amount of time to execute. The most common RISC microprocessors are AVR, PIC, ARM, DEC Alpha, PA-RISC, SPARC, MIPS, and IBM's PowerPC. The idea was inspired by the discovery that many of the features that were included in traditional CPU designs to facilitate coding were being ignored by the programs that were running on them. Also these more complex features took several processor cycles to be performed. Additionally, the performance gap between the processor and main memory was increasing. This led to a number of techniques to streamline processing within the CPU, while at the same time attempting to reduce the total number of memory accesses.

If you read my post on "checkpoint friendly" bags back in July you may be wondering what is going on with this program. Starting on 16 August, the TSA announced they were ready allow compliant "checkpoint friendly" bags through the X-ray machines while remaining in the bags. The TSA always...
Good news on the Dell netbook front
Fri, 05 Sep 2008 18:47:52 -0700
Just a quick update now that I have a minute to sit down tonight. I heard from my Dell rep this afternoon that, although it's not available on the Dell K-12 education pages, the Inspiron Mini 9 is available to all education customers in quantity. Here's...

This is not a PC you load with additional hardware, or much additional software. This is more like a cell phone, something you toss in your backpack and use on-the-run. by Dana Blankenhorn
Yes, we know it's a problem. No, we have no budget.

A survey by data center infrastructure company Voltaire indicates that while a vast majority of data center professionals believe that running a green data center will become a mission-critical agenda item, they haven't set aside the money to support it. Close to 90 percent of the executives...
Possible AMD Q4/08 desktop processor roadmap surfaces
Fri, 05 Sep 2008 10:46:19 -0700
CHW.net has published what seems to be on the face of it a convincing looking AMD Q4 08 processor roadmap that gives us a glimpse into what AMD has in-store for us over the coming months. by Adrian Kingsley-Hughes
Red Hat buys Qumranet, adds gasoline to the spreading VDI bonfire
Fri, 05 Sep 2008 07:56:36 -0700
VDI, somewhat ironically, may also work well for market mover Microsoft as it seeks to slow the momentum to outright web-based and OSS/LAMP-supported applications and services for large businesses. Microsoft must realize that enterprises have had it with the high cost of maintaining and managing the traditional Windows OS in...
