Emulating the CRT for Video Games That Need It

Here is a good article about an effort that was made to make Stella, an Atari 2600 emulator, render the screen according the behavior of a CRT rather than an LCD. The differences are clear, and perhaps more interesting to folks who grew up playing games on such consoles :).
Whatever this case, this must have been an interesting programming problem.

A Maven build number plugin

Here is a plugin to:

get a unique build number for each time you build your project. So while your version may remain constant at 1.0-SNAPSHOT for many iterations until release, you will have a build number that can uniquely identify each build during that time. The build number is obtained from scm, and in particular, at this time, from svn. You can then place that build number in metadata, which can be accessed from your app, if desired.
The mojo also has a couple of extra functions to ensure you get the proper build number. First, your local repository is checked to make sure it is up to date. Second, your local repository is automatically updated, so that you get the latest build number. Both these functions can be suppressed, if desired.
Optionally, you can configure this mojo to produce a revision based on a timestamp, or on a sequence, without requiring any interaction with an SCM system. Note that currently, the only supported SCM is subversion.
