It's not even an issue with the nature of my projects (working on them has been intellectually stimulating and I've learnt a lot from the experience), but that they've been stuck with me months after the innovative aspects have given way to administrative tedium, and what was once a joy to work on (a chance to learn something new!) has become a chore.

That said, it's probably just me being a lazy sack of shit (occupational hazard from studying mathematics, though it was definitely worse once I became a full-time programmer). OP would probably fare better than I did should he decide to follow my path.

>The successor of the smallest non-useful number
Shit, that's exactly the wrong way around.
That should have been "successor of the largest useful number".

It's obviously a joke image.

...Right?

...and I forgot that 0 is non-negative as well. Which means that the correct solution should be to subtract 1 from everything (i.e., Albert has 7 and Bernard has 6).

Do I really have to spell it out?
Let B be any n*n square matrix other than the identity matrix.
Let A be the m*n zero matrix.
Then AB = A but B is not the identity.

If X is a random variable with probability density f(x) on <span class="math">(0,\:\infty)[/spoiler] (e.g. gamma distribution), and <span class="math">b[/spoiler] is a nonzero real, then the density of <span class="math">y=x^b[/spoiler] is <span class="math">f(y^{1/b}) \div \left( \abs{b}[y^{1/b}]^{b-1} \right)[/spoiler].

How does this generalize to random positive-definite matrices? If X is Wishart distributed, for example, what does the density of <span class="math">X^b = Q^TD^bQ[/spoiler] look like?
