The Problem with Electronic Voting Machines.

This is my favorite excert from the article:

We need to start treating voting software like we treat any other high-reliability system. The auditing that is conducted on slot machine software in the U.S. is significantly more meticulous than what is done to voting software. The development process for mission-critical airplane software makes voting software look like a slapdash affair. If we care about the integrity of our elections, this has to change.

The solutions he suggest involve making a paper audit trail so votes can be manually counted if a recount is needed, and making the software source code open source so that the entire community of programmers can work towards improving it and correcting security problems and bugs.
