D’oh! My Vagrant NFS is slow…

Vagrant is great for various reasons. One of them is that you can describe, version and share your virtual development environments as code. By doing this, you can make sure your setup and the one of your colleagues are identical, which avoids “works on my machine” bugs and discussions. Or it helps you to be able to develop two projects without having to fiddle with configs, for example if you want to use https/443 in two projects, you don’t have to reconfigure your web server every time you switch from project A to project B.

Cassandra Test Lab [Tutorial]

Apache Cassandra is a really impressive piece of technology. When it comes to extreme performance requirements, it is definitely a solution one should look into. Yet many times people get bitten by the distributed nature and the fundamentally different process of data modelling, especially when coming from a relational background. Just reading the documentation probably won’t be enough to really get to know Cassandra. You will have to get your hands dirty. In this blog post we present a simple way to create your Cassandra cluster and experiment with data modeling, different configurations, cluster sizes, topologies, query performance etc. Weiterlesen
