Looks like the pieces are reversible, so the two L's and two S's are actually L, J, S, and Z.

Of course, it's only a failing strategy if adopting that strategy causes everyone to adopt the same strategy, which is very unlikely for most people.

This may be wrong for complex reasons. Similar minds making the same decision for the same reasons do not _causally_ influence each other, but that doesn't change the outcome, nor does it make it any less bad. For a fairly deep view into how one might formally describe this particular aspect of decision making, I strongly recommend: https://intelligence.org/files/TDT.pdf

That's the way it should be. Otherwise, you'd be incentivized to leave (dishonestly) positive reviews.

-----


I never claimed there was a good solution, because the point you make is very valid.

One per year? Compared to cars, food poisoning, bathtubs, ladders, and almost anything else you can think of, that's close enough to zero to be a non-issue.

If the receipts are anonymous, they can't prove how you voted, only that you were able to obtain a receipt. So what if we increase the supply of receipts enough to destroy the value of an individual receipt? For example, voting machines could drop duplicate receipts in a bucket that voters have access to.

-----


What you're buying isn't a vote, but a receipt. What if we could increase the supply of valid receipts enough to make them effectively worthless?

For example, voting machines could drop duplicate receipts into a bucket that voters are free to rummage around in.

-----


How would you tell the difference between a valid and invalid receipt when the voter came to verify it?

-----


Or just not have receipts and avoid the issue altogether.

-----


Sure, but there's a benefit to receipts: you can verify that your vote was counted correctly.

-----


Well, you can verify that the receipt says your vote was counted correctly. That assumes you both trust the receipt system and believe that whatever tampering was done to cause your Obama vote to become a Romney vote couldn't have possibly also resulted in the receipt providing incorrect information as well.

-----


Ideally, I think the complete list of votes (with receipt confirmation numbers, but no names, obviously) would be available for inspection.

I find that while a neighborhood filter gets the job done, its usability isn't great, for a number of reasons:

* You have to roughly know the boundaries of all the neighborhoods for the list of names to be useful

* A one-dimensional arrangement of names doesn't correspond well to the 2D relationships you probably care about.

* Many neighborhoods don't map well to regions I care about. I often find myself selecting Bernal Heights, Mission District, and Noe Valley to capture the idea of "the area around 24th and Valencia", for example.

Not to mention realtor creativity in deciding where an apartment is located. The Tenderloin? That's totally practically Nob Hill!

Or just show the subtitles after a short delay. Or show a word-by-word translation in realtime. Or both.

Is lifetime earning to cost a useful metric, though? There are costs outside of college that won't scale with that ratio. Extreme example: a 1000:1 ratio isn't much good if your lifetime earning is $1000, and a 2:1 ratio could mean you come out ahead by a few million dollars.

I get your argument, but the cost is far past $1.

$11,110 per semester out of state for guaranteed tuition plan and $1,185 in fees.

in state is $1,185 in fees and $2,248 per semester.

So here are starting and mid-career salaries (medians) for different colleges:

And I guarantee you 100k a year buys you a MUCH nicer house in Atlanta than in LA (further skewing the value).

Using UDIDs for authentication isn't a good idea for a serious app. Even if it were unspoofable, devices aren't users. Users have iPhones and iPod Touches and iPads; they upgrade; they sell devices to other users.

Let me rephrase - if I were making a game, I wouldn't bother with a username and password. What's the point? Just ask for a nickname when entering the high scores :)
