Moving back to EMC

Beginning of February 2014 I moved back from goPivotal to EMC.

Last year, VMware and EMC (USA) fostered a new company: gPivotal - everything cloud and agile. Among other resources, they also moved Greenplum over into this new startup. This happened in Germany during May/June. However, as some of you may know, I was not very happy with this move and end of last year I finally decided to leave goPivotal.

After submitting my resignation and publicly announcing that I'm looking for something new, I was contacted by a number companies, including EMC (Germany).

Turns out that the companies which upfront expressed the greatest interest are not really interested. And companies which you think they don't have what you are looking for - well, they turn around and offer you something even more interesting.

In the end, after considering various offers, I decided to move to the Digital Applications Work Group in EMC.

Cleanup and reuse unused Copy&Paste disk space occupied by VMware

Whenever you Copy&Paste (or Cut&Paste) something into or from a VMware instance, the software first copies the files into a temporary directory and later on sends the copy/move job to Windows. Since the Windows task is asynchronous, VMware has no chance to find out when this actually finishes - so it is supposed to clean up this temporary directory at boot time.

However, waiting for the next reboot can clog up quite some disk space (when I develop something I often have to copy many files around between several virtual machines and the desktop) - despite that Windows still likes to BSoD on me from time to time. And sometimes VMware does not get the cleanup right at reboot and the files are still there.

So I wrote myself a little Cygwin shell script (you should really consider installing Cygwin when you have to work on Windows) and the execution of this script is scheduled every night by the Windows Scheduler.

Greenplum Community Edition - Connections from the host system into the virtual machine

If you download the Greenplum Community Edition (GP CE) from the Greenplum website and if you want to connect tools like pgAdminIII from your host machine to the database inside the virtual machine, you have to disable the firewall. The CE is installed on CentOS and by default the firewall is enabled and blocks connections from outside to most ports.
