TinyDNS as a Puppet Module

As a data center operator we are in need of DNS handling for our internal servers and appliances. Handling IP’s for everything is not really an option and also changes to servers are much easier to handle if we can use assigned domain names instead of IP addresses. When we started looking at open source DNS servers for the Linux operating system there are really 2 bigger contestants out there in the market: Bind and TinyDNS. This said Bind pretty much owns the market. That comes with advantages and disadvantages. One big advantage of Bind over TinyDNS is the amount of documentation and support on the community. It’s been around for so long you find pretty much any answer to any question you’ll ever have. The big downsides of Bind are its size and the fact that it is used all around. So obviously security vulnerabilities are mostly exploited on commonly used systems since you get more bang for your buck.

The Myth of the Specialized Programmer

Ever heard of it? Apparently there is this mystical creature who is a master of his trade, knows all the tricks in the book and is generally just untouchable. He is the only one that can really solve the programming issues or even come up with any form of useful code in this particular programming language. Hmm... so if I learned to program Java that automatically disqualifies me from successfully programming in C? Or PHP? Or Visual Basic?
