This article is about erasing disc drives securely. Specially for SSD
drives, writing zeros or random data to discs is not good enough and
counterproductive.
One way to do secure erase (for disposal) is to begin with an encrypted

If you often mount and access a remote NFS share on your system, you
will probably want to know how to improve NFS file access performance.

So I finally moved my WordPress web sites to OpenShift.
OpenShift is a cloud based Platform-as-a-Service offering from RedHat. And while there is a learning curve I would say that so far it works great.
My implementation is a fully cloud based solution. Makes use of the following services:
Windows system administration is very mouse driven and to reach
all tools you need to browse through Windows explorer.
If you are like me and prefer to log on a limited privilege account and use Runas to perform admin tasks, you can open these consoles with the .msc file names …
Software package download proxy
