The Opportunity for Parallelism Is Where You Find It
Multicore Can Be More Useful than You Might Think
Ponder this: " ... multicore processors are a hardware development that software is poorly equipped to utilise." That, writes Darryl Gove in his blog on multicore processing and quoting David Patterson's IEEE Spectrum article entitled "The Trouble with Multicore." Gove takes issue with Patterson; in Gove's view, multicore is the solution, not the problem.

A Petabyte: Not as Much as You Might Think
So Don't Waste What You Do Have: Oracle Unified Storage
From the days of thinking a petabyte of storage was unattainable and unnecessary to the present, when a petabyte is scarcely enough, follow along with Marc Hamilton whose blog on the subject leads readers, finally, to what he recommends as the solution: Oracle Sun Unified Storage.

Client Side Partition Alignment and Its Impact on Performance
Some Recommendations on How to Address the Problem
This blog is for users who create and access LUNs from their Sun Unified Storage appliances using either iSCSI or FC and who might not realize the impact on performance that client side partition alignment can exert. Blogger David Lutz characterizes this issue as generic rather than one that involves only Unified Storage appliances but adds, reassuringly, that achieving proper alignment is relatively simple.

    Presenter Console Extension Gives More Control to Slide Show Presentations
    Available with Oracle Open Office and Freely Downloadable with OO.o
    Slide presentations can be relatively stress-free according to Iain Curtain, who shares his recent experience using Open Office installed with the Presenter Console extension at the UK Hyperion conference. Its key feature is the way a presenter views the slide show versus the audience. The presenter is privy to a view of the upcoming slide, the slide notes, and a presentation timer, while the audience only see the current slide being presented.

    "Strategies for Solving the Datacenter Space, Power, and Cooling Crunch: Sun Server and Storage Optimization Techniques"
    Oracle Reduces Datacenter Space by 66%; Operating Costs by 30%
    Recognizing the possibility for economies in datacenter design and management, Oracle has taken on the challenge of finding those economies in its datacenters worldwide. Using the two-fold approach of optimizing power and reconfiguring datacenter real estate, the company has realized reductions in datacenter space of up to 66 percent and decreases in operating expenditures of up to 30 percent. The Oracle white paper "Strategies for Solving the Datacenter Space, Power, and Cooling Crunch: Sun Server and Storage Optimization Techniques" details how this was done.
    The Issue with Incompatible Cables
    Standards are Not Used by All Vendors
    If you have ever experienced incompatibility with cables, know that you are not alone. Joerg Moellenkamp takes a brief look at the common problem, noting that although there is a standard interface that connects DACs to the switches/NICs (SFF 8431), the reality of cable lock-in is quite different.

    VirtualBox Bug Disrupts Autoreset of Differencing Disks
    Blog Discusses Bug, Explains Differencing Disks and Immutable Images

    VirtualBox 3.2 and up, at least to version 3.2.4, ignores the autoreset property of differencing disks, according to The Grey Blog, whose author explains, "This basically means that, after stopping and starting a virtual machine, the differencing disks won't be wiped off automatically hence changes made into your guest instance will be persisted upon reboot." He also offers an introduction to differencing disks and immutable images in a secondary blog entry.
