I wanted to buy an Android tablet but I bought an iPad

Today I went to buy a new tablet for myself, replacing the old iPad that I was not using much. As you can guess by looking at my blog I am an Android fan so I wanted to buy an Android tablet but instead of that I came home with an iPad. I had no other choice here in the Netherland really, I mean really.

Performance of my new laptop

Couple of days ago I got my new laptop (Dell M4700) to replace my old one. I was interested in how it performed compared to my old laptop, to make it more interesting I added my desktop (AMD) to the comparison as well.

VirtualBox vs VMware Player vs KVM

I was testing the performance of VirtualBox and VMware Player when i thought maybe i should test one of the more bare metal hypervisors like xen, kvm or esxi. Xen needs more config than kvm and esxi is without actual host so i decided to try out kvm because it is the easiest one to setup.

VirtualBox 4.2 vs VMware Player 5

Yesterday i tested the performance of VirtualBox and i thought it should be nice to see how it compares against the famous VMware. I chose to test the VMware Player instead of the workstation because it is free. The first big difference between VirtualBox and VMware Player was that the Player did not allow more than 4 cpu's to be assigned.

VirtualBox 4.2 performance in Ubuntu 12.04

I am using VirtualBox for a long time now, although i know there is an performance penalty i never bothered to check how big it was. I got curious and though maybe I should test this to see how it works out. This is not an scientific test or anything fancy just a simple tests that show a difference in performance between the hardware and VirtualBox 4.2.

Security experts are in the old Testers position?

We all know that testing is important and since more and more companies started doing agile we all have learned that testing needs to be done on the go and not at the end of our software development. Where couple of years ago it was very hard to find teams with testers in them now you can find a lot of them.
