Voting Machines Vs. Slot Machines

dmh20002 writes "Being a Nevada resident and knowing people who write code for slot machines, I was aware of the stringent measures the state of Nevada uses to vet the security of slot machines. The Nevada Gaming Control Board audits everything about them, both physical and soft, for unintentional and intentional security holes. Hearing the hoopla on voting machines, the contrast was obvious. Slot machines are about money, which is more important than votes, apparently. Now the state of Nevada is looking at electronic voting machines and plan to apply some of the same safeguards. Just applying the Nevada technical standards for gaming machines and vendors to voting machines would be a start, since there don't seem to be any standards for voting machines. A funny/sad sideline is that in Nevada, every year or two a programmer or engineer goes to jail for exploiting slot machines."

He still gets everyone from 0 - .33X coming to him, but now gets half the people from .33X - .75X, stealing business from guy 2, who promptly moves to .66X to make up for it. Eventually they end up at .49X and .51X (or both at .50X if you want), glaring at each other, each still getting 50% of the business, any intermediate gains lost.

That's why when you count ballots you have representatives of both parties present so that they can all witness what's going on rather than having to trust a ballot counter.

Shortly after this happened, Sandia National Labs came in and audited the Gamining Control Board for free. Turns out they were interested in the gaming industry since they are the only other place where EPROM use is so critical and they had interest in finding out how the board handled it.

      At any rate, Sandia produced a huge report that showed the Board's short comings including being understaffed in the Electronic Services Division. The Board took the report to the legislature and got a budget approved that allowed them to hire more engineers to work in the lab.

    Then consider the real difference choosing a different president or governor will make to your life: not much, really. The two dominant political parties have grown very similar to each other. They'll rarely try to make a significant change (and most changes they attempt will be cancelled out by the other party in the next election). So not only is a vote unlikely to pay off, but that payoff isn't likely to change very much.

    Thus, looking at all the possibilities, a rationally self-interested person will not waste his time voting. The hour+ it takes out of your day is actually much more valuable than the tiny chance that the vote you cast actually has a benefit to your life.

  30. Not in the casino I worked in... Re:Audit trail by Don'tTreadOnMe · · Score: 3, Informative

    I am not familiar with the gambling business, but I know it wouldn't be that hard to alter the slot machine payout ratio from a programming perspective. ~1 line of code, in fact.

    I worked in a casino management company in South Dakota, so this experience applies there:

    It would be very hard to cheat like that for very long. The programs for the slot machines are on a single PROM, and that PROM is registered with the Gaming Commission after exhaustive testing.

    The PROM is installed in the gaming device, and the device cannot be powered up during business hours unless the gaming commission has checked the PROM, watched you put it into the machine, and then sealed it into place with tamper-proof tape that only the Gaming Commission has access to. (They have a little box that they plug the PROM into which tells them if the chip is acceptable or not.)

    Furthermore, the Gaming Commission can come by your casino, any time they want, with no prior notice, and have you open the machines to ensure that the tape is still in place, or to pull the chips for testing.

    I was paid to watch the per centages paid ouit by the slots and the tables to make sure they were within acceptable range. At one Tribal Gaming establishment that we ran, the machines had a lot of play (1,000+ games per day) and tehy _always_ paid out what they were supposed to. If they deviated, we checked them for mechanical malfunction, and then we looked at staff and guests to see if someone had a new scam going. (The easiest is to request a fill on the coin bucket, and then hand the money to your friend instead of putting it into the machine. But that was very easy to catch, too. And look out at the Tribal Gaming establishments: >$100 is a federal offense, so we called the FBI to take care of any shmucks stealing from the tribe.)

    So, if your gaming establishment is having a bad month, tweaking the payout won't help much: Every game was random, and just as likely to pay the jackpot as the previous game.
