Git Symlinks in Windows
Our developers use a mix of Windows and Unix based OS's. Therefore, symlinks created on Unix machines become a problem for Windows developers. In windows (msysgit), the symlink is converted to a text file with a path to the file it points to. Instead, I'd like to convert the symlink into an actual W...
Functional programming - is immutability expensive? [closed]
...bvious disadvantages of a functional quicksort implementation. In the following, let’s consider this reference implementation in Haskell (I don’t know Scala …) from the Haskell introduction:
qsort [] = []
qsort (x:xs) = qsort lesser ++ [x] ++ qsort greater
where lesser = (filter (<...
Is Python strongly typed?
...design choice made when + was implemented, but not really a necessity following from the language's semantics. In fact, when you overload + on a custom type, you can make it implicitly convert anything to a number:
def to_number(x):
"""Try to convert function argument to float-type object."""

lenses, fclabels, data-accessor - which library for structure access and mutation is better
... putting twice is the same as putting once, or rather, that the second put wins.
put l b1 (put l b2 a) = put l b1 a
Note, that the type system isn't sufficient to check these laws for you, so you need to ensure them yourself no matter what lens implementation you use.
Many of these libraries als...
What does O(log n) mean exactly?
...t's versatile as an example. Plus I got to use robots in my explanation! A win all-around. (Also, it looks like your answer was made before I was even a member on StackOverflow to begin with!)

Password hashing functions have now been built directly into PHP >= 5.5. You may now use password_hash() to create a bcrypt h...
What is the performance of Objects/Arrays in JavaScript? (specifically for Google V8)
