Cooling Strategies for Ultra-High Density Racks
The simple answer to this problem would be to provision a data center so that it is capable of providing 20kW of redundant power and cooling to every enclosure. Unfortunately, this is simply not technically feasible or economically practical in almost any case. Making the wrong choices when specifying a data center for high density operation can needlessly increase the lifetime cost of the physical infrastructure by many times. The purpose of this paper is to outline practical and effective strategies for deployment of high density enclosures and blade servers.
Google unveils 'smart contact lens' to measure glucose levels
It uses a "tiny" wireless chip and a "miniaturised" glucose sensor embedded between two layers of lens material. The firm said it is also working on integrating tiny LED lights that could light up to indicate that glucose levels have crossed certain thresholds. But it added that "a lot more work" needed to be done to get the technology ready for everyday use. "It's still early days for this technology, but we've completed multiple clinical research studies which are helping to refine our prototype," the firm said in a blogpost.
How Natural Language Processing Makes Our Lives Easier and Improves Your Business
Talking to computers still requires programming languages but the ultimate goal of NLP is “to do away with computer programming languages altogether. Instead of specialized languages such as Java or Ruby or C, there would only be “human.”” The better a computer is capable of understanding natural language, the more applications there will be, but already NLP offers a lot of possibilities to help grow your business, save money and stay ahead of your peers.
The Year Ahead According to Rackspace
There’s a tacit agreement that many traditional security solutions just aren’t cutting it in our ever changing world of technology innovation. The NSA revelations and general scaremongering does not drive the market away from outsourcing, or from US companies, it drives them into wanting to do more on security, demanding more for their providers. 2014 will see continued investment in new security technologies especially around encryption. This will undoubtedly result in better security in the cloud and address some of those lingering doubts around the security of cloud-based platforms and systems.
Predictive Analytics Can Boost Enterprise Performance
"Using historical measures to gauge business and process performance is a thing of the past," said Samantha Searle, research analyst at Gartner. "To prevail in challenging market conditions, businesses need predictive metrics — also known as "leading indicators" — rather than just historical metrics (aka "lagging indicators")." Predictive risk metrics are particularly important for mitigating and even preventing the impact of disruptive events on profitability.
What makes innovation go wrong
Stephen Di Biase says innovation is "in our DNA. We evolved to get here." Di Biase, a longtime R&D executive, is now president of Premier Insights LLC, which provides consulting services about innovation to science-and-technology-based companies. He is on the advisory board of Clean Energy Trust, and he convenes a Chicago-area network of chief technology officers from companies that range from family-held firms to Fortune 500 companies. He spoke with Blue Sky Innovation about leadership, innovation in larger companies and thoughts for managers to consider when looking for new solutions.
IT mobility trend continues in 2014
It's pretty easy to conceptualize any software component as a resource, an element that does something for us. The problem with that very general approach is that it can lead to over-specifying. If you want to expose the functions of a programmable light switch, it's tempting to have verbs like On and Off and maybe status verbs like ReadState. These are nice, but they force an API into being not only functionally specific, but also limited in terms of what technologies can be used to implement it.
Web steps closer to baking-in support for NFC payments and data swapping
When implemented the spec would allow web pages and apps to read and write to NFC tags; to send and receive messages between NFC-enabled devices and provide a way to initiate a wireless connection via wifi or Bluetooth. The API would enable a range of capabilities for web sites and apps such as tapping two devices together to initiate a two player game; tapping devices to share data such as coupons or contacts; and tapping a device to read a message from an NFC tag.
Better software testing and improved quality starts with the culture
A testing expert who really knows his stuff adds enormous value to the project for the customer—and for the whole team by making their job easier rather than harder. Sadly, too many companies still view testing as more of a necessary evil than an opportunity. That's an attitude that Jim Holmes, Director of Engineering for Test Studio at Telerik, is doing everything he can to change.
Spy agencies around the world use radio signals to tap data from targeted systems
The technology, which has to be physically installed in most cases, has been available since at least 2008. It "relies on a covert channel of radio waves that can be transmitted from tiny circuit boards and USB cards inserted surreptitiously into the computers," according to the Times report. Data captured by the devices are sent to small briefcase-sized relay stations often set up miles away from the target system. The software has apparently allowed the NSA to do an end-run around whatever cybersecurity controls are installed on the compromised systems.
