Why does Date.parse give incorrect results?
...e Input Side
All implementations store their date values internally as 64-bit numbers that represent the number of milliseconds (ms) since 1970-01-01 UTC (GMT is the same thing as UTC). This date is the ECMAScript epoch that is also used by other languages such as Java and POSIX systems such as UNI...
How do i create an InstallShield LE project to install a windows service?
... different. The biggest difference for me right now is the removal of the Windows Installer project. Now we are being forced to use the InstallShield LE (Limited Edition). The problem here is that I write a ton of Windows Services and I can't see how to setup InstallShield LE. It appears that we (m...
Regular expression to allow spaces between words
...^(\w[\w ]*\w)?$
If you want to only allow single space chars, it looks a bit different:
^((\w+ )*\w+)?$
This matches 0..n words followed by a single space, plus one word without space. And makes the entire thing optional to allow empty strings.

Iterate over the lines of a string
... if nl == '': break
yield nl.strip('\n')
at least, it's a bit less verbose. The need to strip trailing \ns unfortunately prohibits the clearer and faster replacement of the while loop with return iter(stri) (the iter part whereof is redundant in modern versions of Python, I believe...
How to write the Fibonacci Sequence?
...== 1, fib(0) == 0, and fib(n) to be:
fib(n-1) + fib(n-2)
Where n is an arbitrary integer. This means that fib(2) for example, expands out to the following arithmetic:
fib(2) = fib(1) + fib(0)
fib(1) = 1
fib(0) = 0
# Therefore by substitution:
fib(2) = 1 + 0
fib(2) = 1
We can calculate fib(3) th...

What's the difference between lists and tuples?
...of__() # 9088
Due to the smaller size of a tuple operation, it becomes a bit faster, but not that much to mention about until you have a huge number of elements.
Permitted operations
b = [1,2]
b[0] = 3 # [3, 2]
a = (1,2)
a[0] = 3 # Error
That also means that you can't dele...
