Why? It sounds incredibly pretentious. I think most people would appreciate Plain English [0].

The number of such mazes is also on OEIS under A007341: http://oeis.org/A007341

Once upon a time dialup was all some of us had, 24/7.

Somehow we coped.

One such system is Hashcash [0], there is an extension for Thunderbird [1] which uses it.

The only thing is that legitimate mass emails (think mailing lists) will be delayed as well, unless some sort of exception is added.

(Fully) Homomorphic Encryption is necessary for this. One of the paper's authors (Craig Gentry) is also the creator of FHE. To quote the paper:

>Using indistinguishability obfuscator for NC^1 together with any (leveled) fully homomorphic encryption (FHE) scheme with decryption in NC^1 (e.g. [Gen09b, BV11, BGV12, Bra12, GSW13])

    Paper: http://eprint.iacr.org/2013/451.pdf

I have not read through the paper (yet, I plan to).

Very nice observation, and yes, natural numbers only. I believe it could be modified to allow for negative numbers.

There is no evidence that this is a Senator or anyone in a position of power. It is more likely that it is just a bored intern.

According to this calculator [0], in one month, you can expect to earn $20,724.53 dollars (ignoring price changes, difficulty changes, and operating costs). This seems too good to be true, however. Invoking the old adage, "In a gold rush, sell shovels."

I wonder what effect all this has on the Bitcoin economy. If everyone begins doing this, then it will become extremely difficult to mine any Bitcoin without any sort of gear. Feathercoin [1] appears to try and stop this, although I am not sure how effective it is.

There is a transcript at explainxkcd (explainxkcd.com/wiki/index.php?title=1190:_Time#Transcript). Perhaps somebody could clean it up and then use it to estimate how long each frame should last.
