fastest MD5 Implementation in JavaScript
...int plus has incremental mode. It doesn't have Base64 o/p but it does have raw o/p (i.e. array of 32-bit int insead of string).
JQuery MD5 plugin: Very simple down to earth but doesn't seem to have raw mode.
JavaScript-MD5: Not as fancy or fast as Spark but simpler.
Example from CryptoJS:

What is the difference between `sorted(list)` vs `list.sort()`?
..., here's our setup:
import timeit
setup = """
import random
lists = [list(range(10000)) for _ in range(1000)] # list of lists
for l in lists:
random.shuffle(l) # shuffle each list
shuffled_iter = iter(lists) # wrap as iterator so next() yields one at a time

How exactly does a generator comprehension work?
...mber from 1 to 10. You can do this in Python:
>>> [x**2 for x in range(1,11)]
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]
here, range(1,11) generates the list [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], but the range function is not a generator before Python 3.0, and therefore the construct I've used is...

What's invokedynamic and how do I use it?
...d to be dumb data holders.
Considering this simple record:
public record Range(int min, int max) {}
The bytecode for this example would be something like:

What characters are forbidden in Windows and Linux directory names?
...klist of characters, you could use a whitelist. All things considered, the range of characters that make sense in a file or directory name context is quite short, and unless you have some very specific naming requirements your users will not hold it against your application if they cannot use the wh...
Getting individual colors from a color map in matplotlib
...0.99923106502084169, 0.74602077638401709, 1.0)
For values outside of the range [0.0, 1.0] it will return the under and over colour (respectively). This, by default, is the minimum and maximum colour within the range (so 0.0 and 1.0). This default can be changed with cmap.set_under() and cmap.set_o...
What's the hardest or most misunderstood aspect of LINQ? [closed]
...g to do a join without the join operator will result in O(n^x): from i1 in range1 from i2 in range2 from i3 in range3 from i4 in range4 where i1 == i2 && i3 == i4 select new { i1, i2, i3, i4}. And I've actually seen this written before. It works, but very slowly.

Pick a random element from an array
