Why is WinRT unmanaged? [closed]
... That won't do, even a company as big as Microsoft cannot afford to create and support a specific WinRT version for every language binding. Nor is it necessary, given that these languages already support COM.

Regular expression: find spaces (tabs/space) but not newlines
...on only considers two white space characters: the horizontal tab (U+0009), and a breaking space (U+0020).

How does '20 seconds' work in Scala?
...
There are a few things going on.
First, Scala allows dots and parens to be omitted from many method calls, so 20 seconds is equivalent to 20.seconds()*.
Second, an "implicit conversion" is applied. Since 20 is an Int and Int has no seconds method, the compiler searches for an impli...
Python - abs vs fabs
...n (if it can't, it throws an exception). It then takes the absolute value, and returns the result as a float.
In addition to floats, abs() also works with integers and complex numbers. Its return type depends on the type of its argument.
In [7]: type(abs(-2))
Out[7]: int
In [8]: type(abs(-2.0))

One of the event handles I wait on is a " StopThread " event so that I can break out of the loop. This event is signaled when from my overridden ...

shutdown -r — Restarts.
shutdown -l — Logs off.

How to duplicate virtualenv

To generate a requirements file, go into your original virtualenv, and run:

What is the best way to count “find” results?
...
find <expr> -type f -printf '.' | wc -c
It will be more reliable and faster than counting the lines.
Note that I use the find's printf, not an external command.
Let's bench a bit :
$ ls -1
a
e
l
ll.sh
r
t
y
z
My snippet benchmark :
$ time find -type f -printf '.' | wc -c

...see an exception like the one you have described.
The usual approach for handling such issues is to register event log sources at installation time (under an administrator account), then assume that they exist at runtime, allowing any resulting exception to be treated as unexpected if a target even...
