HBase is massively scalable -- and hugely complex

Apache HBase describes itself as "the Hadoop database," which can be a bit confusing, as Hadoop is typically understood to refer to the popular MapReduce processing framework. But Hadoop is really an umbrella name for an entire ecosystem of technologies, some of which HBase uses to create a distributed, column-oriented database built on the same principles as Google's Bigtable. HBase does not use Hadoop's MapReduce capabilities directly, though HBase can integrate with Hadoop to serve as a source or destination of MapReduce jobs.

Fedora tips its hat to mobility, cloud, big data

The latest release of Fedora, nicknamed "Heisenbug," is a step towards making Fedora a player in the mobile arena. Fedora 20 also includes more support for cloud, and this is also the first release that supports cheap, low-power ARM processors as a primary architecture, in addition to Intel and AMD chips.

AirMagnet breaks new ground in wireless spectrum analysis

Everyone needs a Wi-Fi spectrum analyzer, but there are times when analyzing cellular spectrum is also essential. Fluke Networks' new AirMagnet Spectrum ES provides a broad range of capability at a very attractive price. Spectral analysis, a longstanding fixture in electronics and manufacturing test, and, more recently as a valuable tool for understanding coverage, interference, and other elements of Wi-Fi, is the art and science of extracting meaning and insight from wireless systems at Layer 1 -- radio waves.

SQL Server 2014 pushes the pedal to the metal

SQL Server 2014 is a significant release with two overarching themes: cloud and speed -- or, to be specific, Azure integrations and in-memory OLTP (online transaction processing). Truth be told, I'm more excited about the speed features than the cloud stuff, but I also understand there is a growing portion of the customer base that is heading to cloud-based operations, and these shops will find the cloud features useful.

First look: Docker is a better way to deploy your apps

A long time ago, a computer program was a stack of punch cards, and moving the program from computer to computer was easy as long as you didn't drop the box. Every command, instruction, and subroutine was in one big, fat deck. Editors, compilers, and code repositories have liberated us from punch cards, but somehow deploying software has grown more complicated. Moving a program from the coding geniuses to the production team is fraught with errors, glitches, and hassles. There's always some misconfiguration, and it's never as simple as carrying that deck down the hall.
