Reason #1: it uses a library written in C. Reason #2: It is not required to write a wrapper. In Java you need lots of wrappers and layers for reasonable abstraction and simplification, in Ruby you don't need this. that leads to much simpler code that can be faster. For example somewhere I have read that Ruby on Rails is actually faster than standard Java J2EE applications, simply because it does not have the many layers in between. PS: glad you like kde-mouse :-) @clayne, I have not done a test, but I believe the Ruby version is faster. Reason #1: it uses a library written in C. Reason #2: It is not required to write a wrapper.

Regardless, you stumbled over yourself with the JPEG example. Using the previous theorem you set forward, "don't repeat yourself" you shouldn't have to repeat all of that complexity with the JPEG writer. WRAP it. They give you that complexityso that you're not left high and dry WITHOUT the complexity when you need it. For your standard run of the mill JPEG compression you should easily be able to write a wrapper function and/or augmentation functions to handle complex one-offs. btw: using your kde-mouse and it rocks.
