How do I get the path of the assembly the code is in?
...etimes gives you some funny results when using NUnit (where assemblies run from a temporary folder), so I prefer to use CodeBase which gives you the path in URI format, then UriBuild.UnescapeDataString removes the File:// at the beginning, and GetDirectoryName changes it to the normal windows format...
Detect the Internet connection is offline?
...n image may not really tell us anything, because we need a useful response from the communication mechanism in order to draw a good conclusion about what's going on. So again, determining the state of the internet connection as a whole may be more trouble than it's worth. You'll have to weight the...
What are the advantages of NumPy over regular Python lists?
...o efficiently implemented.
For example, you could read your cube directly from a file into an array:
x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))
Sum along the second dimension:
s = x.sum(axis=1)
Find which cells are above a threshold:
(x > 0.5).nonzero()

Can anyone explain IEnumerable and IEnumerator to me? [closed]
...erable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you can make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).

What is Ruby's double-colon `::`?
... CONSTANT = 4
end
end
end
You could access CONSTANT from outside the module as SomeModule::InnerModule::MyClass::CONSTANT.
It doesn't affect instance methods defined on a class, since you access those with a different syntax (the dot .).
Relevant note: If you want to go back...

How to print to stderr in Python?
...
I found this to be the only one short + flexible + portable + readable:
from __future__ import print_function
import sys
def eprint(*args, **kwargs):
print(*args, file=sys.stderr, **kwargs)
The function eprint can be used in the same way as the standard print function:
>>> print(...

According to http://blog.rodneyrehm.de/archives/35-Including-Data-From-Github.html, the problem in using
https://gist.github.com/user/605560c2961cb3025038/raw/b75d2...6e8/img.png
is that the b75d2...6e8 part varies per file (a quick experimentation confirms it is the git blob id). How...
Convert two lists into a dictionary
...stead (aliased to zip can reduce code changes when you move to Python 3).
from itertools import izip as zip
So that is still (2.7):
new_dict = {k: v for k, v in zip(keys, values)}
Python 2, ideal for <= 2.6
izip from itertools becomes zip in Python 3. izip is better than zip for Python 2 (...
