RIght now I have a script that I run. When I run it and it hits this line, it starts printing stuff because run.sh has prints in it.

Now notice that
1000 % 8 same bucket as 2000 % 8
1000 % 10 same bucket as 2000 % 10
1000 % 20 same bucket as 2000 % 20

in other words, it would lead to many collisions.
This is because the factorization of 1000 (2...

[a-z0-9_-]
Whether that would cause this problem or not, I don't know.
Additional notes:
The first and last characters are allowed to be any character that isn't - or _ rather than being restricted to a-z0-9
a-z0-9 doesn't include uppercase characters. You need a-zA-Z0-9 for that.

How do I efficiently iterate over each entry in a Java Map?
...
To summarize the other answers and combine them with what I know, I found 10 main ways to do this (see below). Also, I wrote some performance tests (see results below). For example, if we want to find the sum of all of the keys and values of a map, we can write:

Exception in thread "main" java.lang.StackOverflowError
Second try.
Now the idea is even simpler. Primitives in Java can be stored on the stack. So, let's declare a lot of doubles, like double a1,a2,a3.... This script can write, compile and run the code for us:

Compile it via:

And now we're in a place where we can test it:

size = 100000
repeat = 10000
print timeit.timeit(
'np.min(a); np.max(a)',
setup='import numpy as np; a = np.arange(%d, dtype=np.float32)' % size,

Note the cursor is now on the r. Then it outputs d, which overwrites the r and gives us:
