Node.js is an open source runtime environment for server-side and network
based applications. Node.js contains all the components needed to build a
functioning website. But, you need to think of Node.js as a big tool box.
As with any other art form, going to the tool box over and over to perform
the same task is not productive. The concept of tool reuse is used in all
forms of artistry and development is no exception.
What Is a Web Framework
In general, frameworks are code libraries that are created to save people a
lot of time and unnecessary work for repetitive tasks. A framework is a
universal environment that has several key features that distinguish it from
a regular library:
Inversion of control - The control flow of the application is dictated by the
framework, not the code using the framework. Default behavior - Provide a
default set of behaviors yieldi... (more)
One of the great benefits of utilizing a language like Node.js is the wide
assortment of 3rd party modules that are at your disposal. From calculating
the validity of credit card numbers, to managing network connections, the
Node Package Manager (npm) repository has hundreds of thousands of packages
available to you. This article will explain how you can load modules into
Loading and Referencing a Module
In Node.js, modules are accessed either by their name or the file path on the
system. Non-system modules referenced by name will eventually be mapped
into a fil... (more)
PowerShell is definitely gaining momentum in the windows scripting world but
I still hear folks wanting to rely on Unix based tools to get their job
done. In this series of posts I’m going to look at converting some of the
more popular Unix based tools to PowerShell.
The Unix “find” command searches through one or more directory trees of a
file system, locating files based on some user specific criteria. By
default, find returns all files below the current working directory. It
also allows you to perform an action to be taken on each matched file.
In my PowerShell script ... (more)
Last week I posted a PowerShell function library for Microsoft’s newly
introduced search engine at Bing.com. The function library was
appropriately named PoshBing. There was a log of interest in the script so I
quickly moved it off my blog and onto a CodePlex project under PoshBing.
Working on the command line is fun and all, but since I spend a good portion
of my time accessing my twitter account, I figured it would be a bit of fun
to integrate it with my previously released PoshTweet PowerShell twitter
So, after an hour or so of coding it up and creating the @askbing ... (more)

Monitoring Your Network with PRTG - Overview, Installation, and Configuration
In my first article in this series, I talked about the PRTG Network Monitor
from Paessler and how we decided to use it for our DevCentral migration from
our IT datacenter into a cloud provider. In this article, I’m going
to talk about the core of PRTG’s monitoring: it’s sensors.
What is a Sensor?
As the PRTG folks state: A sensor is the “heart” of the PRTG
installation. In it’s essence, a sensor is the term PRTG uses for a
monitor. When you t... (more)
