I've been professionally programming computers since November of 1968 and I can think of no application that is better suited for a computer than the recording of votes in an election. Each question on a ballot is 'binary' in nature. You vote for this guy or not.
It's not like it's a Material Requirements Planning system or a program for pivotal method solving for 100 unknowns from 100 simultaneous equations for crying out loud. All of this BS about these machines voting their own minds is just that BS. However, since the vast majority of the public still thinks that computers are magical machines they are easily led into the realm of tin-foil thinking about these machines.
Can you imagine what Diebold's insurance and bonding costs would be if they were to install code one these machines that tilted one way or the other. Does anyone realize that this code isn't hidden from simple testing, all one has to do is dump the core and look at the machine code to verify what it is doing.
It doesn't take a rocket scientist to verify this, it only takes a good ole hacker and this nation has tons of us.
The problem is not the binary nature of the problem, but the manner of implementation of tracking the results. They use MS Access and have mechanisms in the code whereby an entire table of results can be replaced by another table with no evidence whatsoever.
