Some time ago I wrote a white paper entitled 'PUE is not the Holy Grail of data-centre efficiency'. I had quite a few comments, mostly disbelieving, about the underlying claim that server idle power was high whilst utilisation was low - clearly overshadowing any marginal improvements in PUE that we might be striving for.
Now I will share with those doubters some of the headline facts that need little further explanation:
In the spec_power web-site you will find the majority of commercial servers in terms of Average Watts (when running the spec_power software routine), Idle Watts (when doing 'nothing') and ssj_ops/Watt (a measure of how many of the spec_power operations can be cr... [More]

Apple could launch a new movie service before the end of the year or in early 2012, according to the Los Angeles Times. The paper says representatives from Apple have been meeting with studios to finalize deals that would allow users to buy movies through iTunes and then access them on any iOS-based device.
Although the Los Angeles Times didn't cite iCloud specifically, the report says Apple plans to "put movies in the cloud." That sounds similar to the music, iBooks and document storage features of the newly launched service, so it makes sense that iCloud serves as the backbone for a movie service. It's unclear if movies and TV shows would be downloaded to devices -- as it's curre... [More]

Pioneering computer scientist Dennis Ritchie passed away yesterday at age 70 after battling a long running illness. Ritchie was better known as a co-creator of Unix, but he also invented the C programming language back in 1971.
Jeong Kim, President of Alcatel-Lucent Bell Labs confirmed his passing earlier today. "Dennis was well loved by his colleagues at Alcatel-Lucent Bell Labs, and will be greatly missed. He was truly an inspiration to all of us, not just for his many accomplishments, but because of who he was as a friend, an inventor, and a humble and gracious man. We would like to express our deepest sympathies to the Ritchie family, and to all who have been touched in some wa... [More]

BlackBerry maker Research in Motion and phone networks in several countries were forced to apologize to tens of millions of users yesterday, after a server failure caused devices' Internet, email and Blackberry Messenger services to stop working. The server failed Monday at around 11:00am UK time at Blackberry's data center in Slough, England. The outage caused disruption for handset users in Europe, the Middle East and Africa.
RIM is yet to release a full statement regarding the problem, but a number of phone carriers used Twitter to keep customers informed, including T-Mobile who stated: "There is an issue with BlackBerry services at present. RIM are investigating this at presen... [More]

Summary: Whether you love Apple’s iPhone 4S or hate it, the device is going to have more than its share of ripple effects in the wireless world.
Apple’s iPhone 4S launch has encouraged some consumers and discouraged observers looking for an iPhone 5. Nevertheless, Apple’s iPhone 4S is going to have more than its share of ripple effects in the wireless world.
Whether the iPhone 4S is seen as a success or failure largely depends on whether it expands the market for Apple or is just seen as an incremental upgrade possibility.
Here’s a look at the fallout and the winners and losers.

Summary: In addition to the iPhone 4S, Apple used its October 4 event to officially launch iOS 5 and iCloud — which will be available on October 12, 2011.
In addition to the iPhone 4S, which clearly stole the show, Apple used its October 4 event to officially launch iOS 5 for iPhone, iPad, and the iPod touch and iCloud.
Unlike the iPhone 4S, which is only an incremental update, iOS 5 is a major upgrade that changes the complexion of Apple’s mobile OS and adds a number of new features.
Most notable new iOS 5 features:
Notification Center — Track new email, texts, friend requests, and more in one convenient location
iMessage — Send unlimited text messages v... [More]

Summary: When suppliers try to tie their technology to misleading catch phrases, does it really work for them or just create more market confusion?
Over the years, I’ve watched several attempts to brand products with a new catch phrase that shows a frantic rush for suppliers to look bigger than they really are. Often this begins with a generally accepted phrase. That phrase is then attached to something else in the hopes that it will make the product or service appear well known and acceptable. In the end, it is unnecessary confusing.
An example from long ago was when Oracle started describing their database clustering technology as “grid computing.” The folks ... [More]

Host Net India, Indian based network services company has launched shared hosting plans targeted towards bloggers, forum communities, personal websites, and small businesses.
Employing Cloud Linux is one feature that helps shared hosting become more of a reliable resource vs using Linux without the ability to limit one site's resources should they get a sudden influx of traffic. Cloud Linux ensures that other customers on a single shared hosting server can reach their sites while the site that is receiving a large influx of traffic if it goes to a certain extent can be throttled to ensure others are not impacted. This is a good compromise between standard shared hosting and a Virtual Privat... [More]

As a security researcher, I regularly come across software vulnerabilities. Some can have a deep and lasting effect on the way customers and clients view the security of the organization and some can have a fairly minimal impact. However, when there are applications susceptible to a few basic types of attacks, I struggle to understand how these can continue to slip through each phase of development and into production. Frankly these types of vulnerabilities are simply irresponsible and dangerous to the end users.
There are a handful of vulnerabilities that fit into this group; cross-site scripting (XSS) being one of them – and we find them in just about every application we test. An X... [More]
