Non-blocking UDP datagram replicator

A class that listens to a UDP port and collects all the datagrams and then rebroadcasts those datagrams to other ports. This is useful for several reasons. I use it when stress testing UDP clients because I can subscribe to 1000 client sockets while only really having a single legitimate datasource.

Integer IP Addresses

I know that every couple of years I need the snippet of code that helps me convert the integer version of an IP address back and forth to a string. You would think that after all this time I’d be able to write it blind.

Simplify Unit Testing With Dependency Injection

After you read a bit about dependency injection you might say “So what? There isn’t much of a practical gain” and an the surface I actually agree with you, I mean how many instances are there where we really need to be able to create infinate class permutation without using subclassing? I believe the [...]

Comparison of Continuous Integration Servers

Tivo Detection: Network Discovery

I’m sure that you know if you have a Tivo or not, but I’m providing a class based on the “Tivo Connect Automatic Machine Discovery Protocol Specification” that will listen for the Tivo UDP heartbeat and provide a notification when the heartbeat is detected.
Usage:
