A Practical Glossary and Discussion of Relevant Terms, Concepts, Models, and Measures
An important aspect of ERM is the strong linkage between measures of risk and measures of overall organizational performance. Thus, this glossary begins with a description of some key corporate performance measures, after which successive elements of the ERM process (risk assessment, measurement, modeling, management applications, monitoring, and oversight) are described.
OLTP Performance of Exadata vs SSDs vs Violin Memory Flash Array
Ashminder Ubhi writes about his experience of running some performance tests against Exadata, SSDs and Violin Memory. The approach was to test the storage performance of the three configurations so he used the great SLOB OLTP type benchmarking tool developed by Kevin Closson. SLOB is very easy to setup and each test run is always consistent unlike some of the other available tools.
Being more agile with Acceptance Test-Driven Development (ATDD)
ATDD seems to offset the increase in development efforts since it allows the whole team to collaboratively discusses acceptance criteria, with examples, and then distills them into a set of concrete acceptance tests before development begins. This ensures that everyone has the same shared understanding of what is actually being built. It may also facilitate a better shared understanding and definition of what it means to be Done.
Five smartphone and tablet trends from Mobile World Congress
This year's MWC may have been lacking in high-end smartphone launches, but the "W" stands for "world" and lower-cost models shown this week are needed to open up the mobile-phone market to more people globally. Here are some of the trends that indicate where the smartphone market is headed.
What's wrong with the Gartner Hype Cycle for Cloud Computing, 2012?
There is a big difference between the description of phases of the cycle on the curve, such as "Trough of Disillusionment," and the report's table of contents, which labels sections by describing the transition between phases. The curve shows Infrastructure as a Service (IaaS) on the upslope of the trough, yet Gartner places it in a section titled "Sliding in to the Trough." This creates two very different perceptions.
An introduction to Firefox OS for mobile developers: Q&A with Andreas Gal, Mozilla
With the first device manufacturers expected to launch Firefox OS devices at Mobile World Congress this month and with major network operators inline to release them to consumers in early 2013, Mozilla’s new operating system (OS) is starting to make waves. Firefox OS is open-source, Linux-based and Web-friendly. mobiForge gets the low-down from Mozilla’s vice president of mobile
Applying big data approaches to information security a challenge
Unlike conventional security approaches that are focused largely on blocking attacks, the new approaches emphasize breach detection and response almost as much as breach prevention. The goal is to help companies block the threats they can while helping them detect and respond to the ones they miss. Instead of deploying point products and perimeter defenses, companies need to adopt a security model that is based on actual threats and threat intelligence, Coviello said.
New Hadoop distributions proliferate
Just in time for the O'Reilly Strata conference, three companies in the tech world have announced new distributions of Apache Hadoop, the open-source, MapReduce-based, distributed data analysis and processing engine. Hortonworks Data Platform (HDP) 1.1 for Windows,EMC/Greenplum Pivotal HD, and the Intel Distribution for Apache Hadoop have all premiered this week on the big data stage.
Asian users go DIY with BYOD
Companies in Asia are not rendering enough IT support to help employees use personal devices for work as part of the bring-your-own-device (BYOD) movement. This is pushing workers to find their own ways to access corporate networks or data via their gadgets, and inadvertently risks creating security holes for potential company data loss or theft.
Microsoft Strikes Back At Amazon With Windows Azure Community Portal
Microsoft unveiled the Windows Azure Community portal, which provides dozens of popular open source applications and language runtimes contributed by partners. Even more recently, Microsoft took this a step further and made the images from the portal available directly in the Azure console, so they can be easily deployed onto Azure infrastructure. By making it easier to deploy third-party apps on its cloud, Microsoft is helping to grow its own ecosystem while increasing the utilization of its infrastructure.
