Suppose we will fetch some Amazon AWS news into a MongoDB database. These few lines made it possible with the use of Groovy and the Gmongo module:
A substantial part of the people I encounter present using OSX on a Macbook. I am not sure how much of these people use Apple’s Keynote for presenting, but I like Keynote very much for various reasons, like a cleaner interface. This blogpost is about some handy tips and tricks I learned using a few years of presenting around the world. If you don’t use OSX, this blogpost is probably not for you.
After we find out how replication works with MySQL lets look at mongoDB
Use the following steps to implement mongoDB Replication:
Yesterday I received a mail from Microsoft: “Congratulations 2012 Microsoft MVP”. For the third year I may call myself Microsoft MVP.

In my previous post about perf I showed how it can be used to determine the function which is used the most systemwide.
Yesterday, I installed a fresh Java EE application server to run a test on an application I was working on. The installation of the application server was as simple as unzipping a distribution archive. As with most application servers, the server could be started by running a shell script from the command line. This was all familiar to me, as I already had another instance of the same server installed on my MacBook. However, when I tried to run the script, I got surprised by an error message:
