Box 2D Type Error in Flash

box2derror

If you are using Box2DFlash v2.1a with Adobe Flash Professional CS6, you may encounter the following error message upon trying to compile any of the examples under Box2DFlashAS3 2.1a\Examples\:

Source\Box2D\Dynamics\b2World.as, Line 871 1046: 
Type was not found or was not a compile-time constant: 
  b2Fixture.

This compile error occurs in Benchmark.fla, HelloWorld.fla, as well as because the project Target has been inadvertently set to Flash Player 9. Simply change the Target to Flash Player 10.3 or above to eliminate the compilation error.

GPG Key Updated

After nearly a decade, I have generated a new 4096-bit RSA PGP/GPG key. The new key reflects the latest OpenPGP best practices. You can also view my key transition announcement for instructions on obtaining this key. The transition announcement has been signed by both the old and new (replacement) key.

If you are using gpg, you may want to add the following to your ~/.gnupg/gpg.conf configuration:

personal-digest-preferences SHA512
cert-digest-algo SHA512

in order to prepare for the eventual migration off of SHA-1 in OpenPGP.

Bot Detection in Casual Games

An article on our work in using low-level input characteristics as a mechanism for bot detection has appeared in The Abstract, the official blog of the NC State Newsroom. Bot detection is one of many possible applications in the broader research context of how computational approaches to evaluating input interactions can be leveraged in order to better understand and predict the underlying cognitive processes of a user.
