hackware 

Software that works well but is difficult to maintain due to the fact that it was written in haste and without consideration for tasteful or proper design.

Most of the stuff I write at work is total hackware.

Hackward Compatible 

When a user writes workaround code to deal with a software bug, and then the programmer later fixes the bug which breaks the workaround code. It is not hackward compatible.

User: This update broke the software!
Programmer: No, the update fixes the software, it simply is not hackward compatible.
