How to round up to the nearest 10 (or 100 or X)?
...
If you just want to round up to the nearest power of 10, then just define:
roundUp <- function(x) 10^ceiling(log10(x))
This actually also works when x is a vector:
> roundUp(c(0.0023, 3.99, 10, 1003))
[1] 1e-02 1e+01 1e+01 1e+04
..but if you want to round to a "nice"...

How to pass an ArrayList to a varargs method parameter?
...toArray(new WorldLocation[locations.size()]))
(toArray(new WorldLocation[0]) also works, but you would allocate a zero length array for no reason.)
Here's a complete example:

Relationship between SciPy and NumPy
...mespace is included into scipy when the scipy module is imported.
The log10 behavior you are describing is interesting, because both versions are coming from numpy. One is a ufunc, the other is a numpy.lib function. Why scipy is preferring the library function over the ufunc, I don't know off the t...

Algorithm to find Largest prime factor of a number
... very fast in general.
The best known method for factoring numbers up to 100 digits long is the Quadratic sieve. As a bonus, part of the algorithm is easily done with parallel processing.
Yet another algorithm I've heard of is Pollard's Rho algorithm. It's not as efficient as the Quadratic Sieve i...
