From: Obsolete Skills (specifically Programming in Java):

"Colleges, however, notorious for teaching things that will never be useful in the real world, have latched on to Java as this wave of the future."

While trying to write a CUPS filter, I needed to add an image to a PostScript document. There are some handy PostScript functions for importing design elements in direct PostScript, but I only managed to get the PNG function working which embeds an image using ASCII85 encoding. The only problem: how to encode a PNG image into ASCII85.

Jarmor "is a tiny collection of java filters implementing ASCII armors" - which includes ASCII85, but aside from the source code, I found the download package didn't contain any examples, only tests and API documentation. Some people will find that perfectly adequate, but I prefer some simple examples so I can quickly use the code: EncodeFile will take the filename of an image as an argument and output an ASCII85 encoded version suitable for use in a PostScript document (place the unzipped .java file in the 'src' directory of the unzipped 'jarmor-1.0-src' download and compile in the usual manner).

If you have some Java code which doesn't have a GUI but uses AWT and "launches" an application (rather than executing solely from the command line), then you should investigate Using Headless Mode in the Java SE Platform.

As part of my structured Ph.D. I must take 4 final year undergraduate modules in my first year. The assessment for my Natural Computing module is to write a conference paper based on the topics covered in the course: my submission is a Travelling Salesman Problem Genetic Algorithm.
