You've found your way through the twisty maze of little passages (or is that the maze of twisty little passages?) to a web site that's focused mainly on the OpenVMS operating system. Herein are discussed such topics as OpenVMS systems management and programming, tuning, operations automation, security, disaster recovery planning, hardware configuration and specification and more.
If you have an interest in any of these fields, you will probably find something to read here.
There are even sometimes articles that are not related to OpenVMS (or even computers). In the past, there's been stuff about linux, space, web standards, and even general programming.
If you're still wondering what this is all about, the tag cloud might give you a quick overview.
