  • OpenShift for Platform as a Service Clouds

    At the Fedora 20 release party another guy stepped up and presented+demonstrated OpenShift, which was the most interesting new feature from Red Hat for me.

    I spent a few days to figure out how to make a simple conversion of a DBF file into a plain text file as comma separated values (CSV) or tab separated values (TSV) in a batch/command line way. I was almost setting up an OpenOffice.org server because it seamed to be the only packaged solution to…
