Techworld.com - The downside of the cloud
Techworld.com - The downside of the cloud: "Saving work and expense is a key reason why cloud services are expected to grow in the next few years. Last year, 4 percent of worldwide IT spending went to cloud services, and by 2012 that figure will be 9 percent, according to research company IDC. Because of its cost and space requirements, data storage is a prime candidate for using cloud technology, and IDC predicts storage will grow from 8 percent to 13 percent of cloud spending in that same period."

Why a 'Google Web Drive' Won't Kill Windows, the PC or Anything Else | Epicenter from Wired.com
Why a 'Google Web Drive' Won't Kill Windows, the PC or Anything Else | Epicenter from Wired.com: "There are two essential problems with the whole cloud computing paradigm that no one has really solved.
The first is trust. It’s one thing to trust your e-mail to Google, it’s another thing to trust the company with the entirety of your digital life. Forget problems of security and privacy, even the basic issue of server downtime leaves many people cold.
The other big issue with online storage is that, for most of us, documents like spreadsheets, word processor files and the other formats that Google Docs understands are not what’s taking up the majority of space on our drives. Is the fabled GDrive going to store and sync my 200 or so gigabytes of mp3 files? For free? Somehow I doubt it. What about movies? If you’re like most of us GDrive will likely affect only your Documents folder — maybe four or five gigs worth of files, but hardly a substitute for your hard drive. Microsoft’s Live Sync service already offers exactly that and it hasn’t changed the way we use Windows, nor has it made us throw out our hard drives."

EETimes.com - Going green with DDR3 memory
EETimes.com - Going green with DDR3 memory: "Industry experts concede that about 82 percent of the $500 million bill for a typical large data center is going toward the facility's mechanical and electrical infrastructure.
For the data center server, one contributor to this higher power density is the memory subsystem. A typical 1U server requires a 600 to 1,000-W supply for its power. These high-end servers used in data centers support between 16 to 18 DRAM slots. On a DDR3 (double data rate 3) system, each single slot draws on average 9 W, using a typical 2-Gb module. The total memory subsystem power is around 144 to 162 W, which is nearly 25% of the available power for the system. Multiplying this by the power draw of 40,000 to 80,000 servers in a typical data center translates to between 5 to 13 MW (megawatts), just for the memory subsystem. Over 13,000 American homes can be powered using that same amount of power"

Cloud Computing 2009 New Year’s Resolutions
Written by Michael Sheehan on Dec 29th, 2008 | Filed under: Cloud Computing, General, GoGrid, Hosting, Industry, ServePath
new_years_hat The start of a New Year is upon us so it is time to get a list together of things that you will do (or do your best to do) in the coming year. Everybody has their own personal Resolution lists, but what about your Business ones? How are you going to remain competitive? What steps are you going to take to cut your budget to remain lean and mean? Are you going to stick with your current methods or adopt some new strategies?
Here are some “Resolutions” that you can think about as you ready your business for 2009.
1. Invest some time in understanding the term “Cloud Computing” – there are several easy-to-understand definitions and movies that have come out that make Cloud Computing a bit more understandable. This one was done at the 2008 Web 2.0 Expo. Then came the GoGrid “Cloud Computing in Plain English”. Recently, there is a new “In Plain English” from the actual Common Craft folks (whom we got our inspiration from). And here is a more technical presentation that came out recently. Regardless, there are lots of sources out there for quick understandings. I have been maintaining a Bookmark RSS feed as well of many of the Cloud Computing blogs and sites. Subscribe to that feed for updated links. Also, read through the popular Cloud Computing Group on Google. Lastly, you can check Wikipedia for their ever evolving definition of Cloud Computing.
2. Do some research on different Cloud Providers – no Cloud Computing provider is the same, and the differentiation is continuing. Last year (2008), I introduced the idea of the Cloud Pyramid which has Cloud Applications (SalesForce) at the top, then Cloud Platforms (Google App Engine or Microsoft Azure) in the middle and finally Cloud Infrastructure (GoGrid and Amazon EC2) as the bottom foundation. Also hooked into it are Cloud Extenders (e.g., Amazon’s SQS) and Cloud Aggregators (RightScale). It’s pretty obvious that there are many choices to be made and that these are very specific to the type of business you are running. In fact, we will be further segmenting the IaaS (Cloud Infrastructure) section more over the next few weeks. Briefly, GoGrid is now being positioned as a “CloudCenter” (which is essentially, a DataCenter equivalent but in the Cloud). More on that later. In the meantime, compile a series of questions for yourself and for your prospective provider. We will get a list together of things you might want to ask (post to come).
3. Review your IT Budget – If you are like most companies out there, you are going through your 2009 budgeting (or have done so already and are probably on your 10th revision now). One way to make your CFO happy is to reduce your Capital Expenditures (CapEx). The easiest way to do that is to really take a hard look at Cloud Computing. If you can slash your CapEx spend by downsizing your physical server footprints, you can easily upsize that same footprint in the Cloud.
4. Empower your Programmers – Cloud Computing offers something new to Programmers: the ability to programmatically control their IT infrastructure. Using an API, Programmers can skin the functionality provided by Clouds as well as develop “intelligent” applications that scale dynamically, for example.
5. Empower your IT Staff – Be sure that you don’t ignore your IT Staff as you look at the Cloud as a physical IT infrastructure alternative. They have some best practices and standards that should be incorporated in what your IT strategies will be. Let them experiment with the Cloud so that they fully grasp what it can do for your organization. They may tell you that it is a great direction to go in, or, they may say that your current infrastructure simply cannot be ported to the Cloud. There may also be some hybrid solutions (like GoGrid’s Cloud Connect) that will give them the best of both worlds.

Finding distinction in 'infrastructure as a service' | The Wisdom of Clouds - CNET News
To briefly recap the cloud market for context, commercial cloud computing has traditionally been seen as consisting of three distinct offerings:
software as a service (SaaS): Complete application systems delivered over the Internet on some form of "on-demand" billing system. Examples include Salesforce.com, WebEx, and Workday.
platform as a service (PaaS): Development platforms and middleware systems hosted by the vendor, allowing developers to simply code and deploy without directly interacting with underlying infrastructure. Examples include Google AppEngine, Microsoft Azure, and Force.com.
infrastructure as a service (IaaS): Raw infrastructure, such as servers and storage, is provided from the vendor premises directly as an on-demand service. Examples include Amazon Web Services, GoGrid, and Flexiscale.
What Randy is arguing, however, is that there is a clear distinction between the service ecosystem approach of Amazon Web Services (which he calls an infrastructure Web service) and a more utilitarian infrastructure-focused cloud service such as the ones many of the hosting companies-turned-cloud providers have produced, including GoGrid, Flexiscale, and Rackspace CloudServers. He calls those companies providers of "cloud centers."

Engineering Windows 7 : Windows 7 Energy Efficiency
Engineering Windows 7 : Windows 7 Energy Efficiency: "The base hardware platform is really dictated by the system manufacturer. The customer gets the ultimate choice when they buy a system—the customer can buy a system with ultra-efficient hardware components or can buy a system with components that favor performance over power consumption. There are desktop and mobile PCs in all kinds of form factors, with varying capabilities and power consumption levels. Some mobile PCs have a normal 3 or 6-cell battery, while others have an extended 9-cell battery or another external battery that can be added to the computer. The challenge for Windows is to be energy efficient across the wide range of hardware in the Windows ecosystem. Looking at a modern laptop, here is where the power goes:

Frequently Asked Questions - Mininova
Frequently Asked Questions - Mininova: "Mininova is entirely written by us (the admins) in PHP. It doesn't use any template or other system, because they are all too slow. Mininova is running on 4 webservers, 4 database servers, 2 search servers, one NFS server, and one load balancer (plus 5 additional servers for the forum, blog and the ads).
We use LightTPD as webserver because with a lot of hits it's just faster than Apache (which we used to run). Mininova makes heavy use of XCache to cache compiled PHP scripts.

We use LightTPD as webserver because with a lot of hits it's just faster than Apache (which we used to run). Mininova makes heavy use of XCache to cache compiled PHP scripts.

IBM Completes ILOG Business Events Planning Acquisition | Business 2.0 Press: "IBM has just completed its $340 million acquisition of ILOG Inc. ILOG is a Pairs based business rules engine maker. The systems provide business intelligence and allow executives to make better decisions based on events analysis. IBM was interested in taking over ILOG as IBM felt the merger would allow businesses to process and monitor more complex events with the ILOG systems. More companies are beginning to enter the events planning space, including Oracle and Streambase."
Multivariate normal distribution - Wikipedia, the free encyclopedia
Multivariate normal distribution - Wikipedia, the free encyclopedia: "Multivariate normality tests
Multivariate normality tests check a given set of data for similarity to the multivariate normal distribution. The null hypothesis is that the data set is similar to the normal distribution, therefore a sufficiently small p-value indicates non-normal data. Multivariate normality tests include the Cox-Small test [3] and Smith and Jain's adaptation [4] of the Friedman-Rafsky test."
