We have previously provided a Quickstart guide to standing up Rackspace cloud
servers (and have one for Amazon servers as well). These are very low cost
ways of building reliable, production ready capabilities for enterprise use
(commercial and government). And Bryan Halfpap has provided a Quickstart
guide which shows you how to build a Hadoop Cluster (leveraging Cloudera’s
CDH3). Using Bryan’s guide you can have a Hadoop Cluster up and running
in under 20 minutes.
With this post we would like to provide you with some additional tips that
flow from these other posts. We will show you how to build clusters even
faster using another common tool in community use, Whirr.
What is Whirr? Apache Whirr is a set of libraries for running cloud
services. Here is more from http://whirr.apache.org/
Whirr provides:
A cloud-neutral way to run services. You don’t have to worry a... (more)

parsing plugins.
The interface and behavior of M3 stayed exactly the same, however now it is
much easier to obtain data f... (more)

automates deploying your Silverlight applications to SharePoint and can
really save you a bit of time. We took a look at how the Visual Web Part
works in VS11 a while back. Now, let’s see what happens when we use
Silverlight.
To work with Silverlight,you can either create a new project or simply add a
new item to an existing project. I’ll start by creating a new project by
choosing the item SharePoint 2010 Silverlight Web Part. Remem... (more)
The Internet is a great resource, but it is sometimes too much to wade
through hundreds of web pages looking for tips about using Tomcat with a
database. So we at Monitis have done it for you! Below are some of the more
useful tips found in various places on the Internet.
Tip #1 – Don’t Ignore Database Performance
Webapps typically use databases. So, you have to tune the webapp along with
the database if you want optimal performance. Take our advice. Performance
test the database and define an appropriate database connection pool
