That's actually not meaningless, it precisely tells me when you use your computer.

No, the vast majority of those files are either Windows files or program files, most of which preserve their last modified time (i.e. last modified time is when the file was actually made, not when it was copied to the computer).

Also the inconsistency between "OK" and "Ok" on that last comic strip irritates me.

I think it's because each comes from a different person and every person has a different kind of diction.

Sine of Tangent of X:

Sin(Tan(X)).

That was the only thing I could think of as being meaningless.

I made a python script awhile ago to make charts from my IRCCloud logs.

There aren't any units on the Y axis, so I assume this is estimated wiener quotient or something.
Since Kerm has the most of this whatever-score, obviously, more is better. So no worries Tari, we normal folks are more or less in the middle of this graph. Not too good, but not too bad either!

How about a random "function"?

This got me thinking, is this even a function? Sure each input gave a single output, but asking the calculator to graph it again given the same input function will result in a different output...

EDIT: I had not thought very hard about how these numbers were generated and have been enlightened by Nik indeed, assuming the seed is part of the input, then there is nothing very special about these graphs! Although in a more hypothetical non-calculator related instance where no seed is needed and random numbers are plucked out of thin air, then such a graph would be entirely meaningless

Assuming the seed of the rand function is part of the input, you will have the same output for the same input.

I remember once making a Tunnel game that used randomized graph equations to draw roads. This got me thinking, is this even a function? Sure each input gave a single output, but asking the calculator to graph it again given the same input function will result in a different output...

Have a look at this Graph!
