Hearts is a little card game for four persons.
A computer version of the game comes with Microsoft Windows and is a pretty popular little thing. When I switched to using Linux, I really wanted to play it, but I didnt find anything at all, so I decided to write it myself and here it is.
Enhancements:
Fixed all known bugs:
- The card passing was always to the right.
- Portability issue regarding setting the random seed (std::random_shuffle + std::srand issue).
- A lot of processes were left running.
- Only one match (ie, a series of games until a player gets 100 points) was possible.
- Status bar tells the user what he he should do at every step (play, give cards right, etc.)

Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.
