The end of the raised floor data center? Maybe not

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“At some point in the future, I think we’re likely to see most of the power and cabling overhead with the raised floor used mainly for water piping to serve cooling needs of close-coupled cooling systems.”Robert McFarlane

Today’s WhatIs.com Word of the Day is raised floor, a data center construction model in which a slightly higher floor is constructed above the building’s original concrete slab floor, leaving the open space created between the two for wiring or cooling infrastructure.

Although raised floors have been the norm in the modern-day data center, we have recently begun to see a return to construction that puts power and cooling above the hardware instead of below it.  It’s being pushed as being a “green data center” solution.  For one thing, putting the cooling system in the ceiling and allowing physics to let the cold air fall uses less power.

Overheard talking about noisy text

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
Text analytics — also known as text mining or text data mining — helps organizations identify and understand what people think about them, their products and their services. The software, which combines advanced search techniques with speech-pattern-recognition capabilities, allows users to quickly scour mountains of unstructured or free-form text in the hope of identifying trends in customer sentiment that will ideally lead to positive change.

Mark Brunelli, Text analytics tools require serious devotion to customers

Today’s WhatIs.com Word of the Day is noisy text, electronically-stored communication that cannot be categorized properly by a text mining software program.

Predictive modeling – rolling the dice in the real world

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Predictive modeling allows for more informed marketing decisions and more effective resource allocation. Instead of blasting the same offers to everyone, you can target multiple offers by segment or focus on particular customer groups based on current or potential value.”

Colleen Ryan, Predictive Modeling: Turning Data Into Insight

Today’s WhatIs.com Word of the Day is predictive modeling. It’ s used a lot in customer relationship management (CRM) and enterprise resource planning (ERP).

Colleen Ryan does an excellent job explaining how predictive modeling works. While it might seem like voodoo, it’s really mathematical. Remember learning about probability and outcome back in sixth grade? Well, in the real world, its not just about rolling a pair of dice.

Or maybe it is.

Maybe trying to predict outcomes of any kind is still just…gambling.

Overheard talking about Cassandra

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
For many years, open source was seen as a trailing effort to proprietary projects. In the big data/NoSQL space, this has been turned on its head. Cassandra is a really good example of how openness is leading the development of next-generation infrastructure technology.” — Joe Brockmeier

Today’s WhatIs.com Word of the Day is Cassandra, a highly-scalable NoSQL open source database system that was created for Facebook but has since become a top-level project over at the Apache Software Foundation.  Cassandra’s claim to fame? She can handle hundreds of thousands of requests per second.  According to Apache,  the largest Cassandra production cluster as of this writing exceeds 300 terabytes of data over 400 machines.

Overheard talking about coaxial cables

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
Coaxial cables use a single copper conductor at the center, insulated by a plastic layer and a braided metal shield, which blocks interference. Coaxial cables are hard to install, but can support greater cable lengths than twisted pair.” — Carrie Higbie

Today’s WhatIs.com Word of the Day is conductor. Conductivity, in general, is the capacity to transmit something, such as electricity or heat.

An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. A substance that does not conduct electricity is called an insulator or dielectric material.

Overheard talking about Digg and Cassandra

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
Built on mostly open source software and commodity hardware, Digg dropped its open source MySQL database in favor of Cassandra, a non-relational, “NoSQL” database that was developed by Facebook and handed over to the Apache Software Foundation.” — Rob Barry

Today’s WhatIs.com Word of the Day is Digg, a social news site that allows members to raise the visibility of stories they like best and bury stories they don’t like. Digg was launched back in 2004.

Overheard talking about security-awareness training

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
Too many companies rely on the computer-based security training courses that each employee must complete once a year to meet compliance requirements.” — Bob Rudis

Today’s Whatis.com Word of the Day is security awareness training, a formal process for educating employees about corporate policies and procedures for working with information technology (IT).

With all the pressures a busy security manager has to deal with, documenting end user security awareness is often low on the list.  That’s why computer-based training (CBT) is so popular.

Unfortunately, CBT can be boring.  It’s SO boring, in fact, that in education it’s often referred to as “drill and kill.”

At last, it seems as if security end user awareness trainers are taking a look at how elementary school educators keep drills interesting — they turn them into games and personalize them.

For instance, if you were an elementary teacher and had to get your students through a daunting amount of word problems to prepare students for standardized testing, you might substitute the names the textbook uses in the word problems for that of your own students and insert students photos or drawing next to the problem.

Or you might turn a drill into a game of Pictionary or Jeopardy or Wheel of Fortune.  The bottom line is that anything you can do to make learning fun is as important for adult learners as it is for young ones.

Overheard talking about careers in business process management

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
“Recruiters aren’t yet specifically looking for candidates who are certified in BPM. In fact, of 67 BPM job descriptions the Gartner researchers examined, not one included a requirement for BPM certification. Instead, most were seeking hard skills such as Business Process Modeling Notation (BPMN) and Six Sigma, and soft skills such as change management.” — Anne Stuart

Today’s WhatIs.com Word of the Day is business process professional.  The Association of Business Process Management Professionals is offering a new certification for business process pros which is renewable every three years.

Overheard talking about context-aware network access control

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
quotes and quotations “There are techniques that can determine the context of access — the type of device, where it’s accessing from, who the user is, [whether it’s] legitimate access to this data or application — and use those techniques to begin to build a policy around what is and what is not appropriate for these devices, which are usually not managed, period.” — Scott Crawford

Today’s WhatIs.com Word of the Day is context-aware network access control (CANAC)an approach to managing the security by granting access to network resources according to contextual-based security policies. The endpoint device is granted access, quarantined or blocked from the network depending on the device’s type, location, identity and the operating system or applications running on it.
