Equivalent C++ to Python generator pattern
...ist in C++, just under another name: Input Iterators. For example, reading from std::cin is similar to having a generator of char.
You simply need to understand what a generator does:
there is a blob of data: the local variables define a state
there is an init method
there is a "next" method
ther...
Display date/time in user's locale format and time offset
...g methods will provide localized output.
Example:
// This would come from the server.
// Also, this whole block could probably be made into an mktime function.
// All very bare here for quick grasping.
d = new Date();
d.setUTCFullYear(2004);
d.setUTCMonth(1);
d.setUTCDate(29);
d.setUTCH...

Perl flags -pe, -pi, -p, -w, -d, -i, -t?
...ion :-)
The command line switches are all detailed in perlrun. (available from the command line by calling perldoc perlrun)
Going into the options briefly, one-by-one:
-p: Places a printing loop around your command so that it acts on each
line of standard input. Used mostly so Perl can beat ...
Fill SVG path element with a background-image

How can I shuffle an array? [duplicate]
...rray);
Implementing prototype
Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr...
Is False == 0 and True == 1 an implementation detail or is it guaranteed by the language?
...
False is a bool. It has a different type. It is a different object from 0 which is an integer.
0 == False returns True because False is cast to an integer. int(False) returns 0
The python documentation of the == operator says (help('==')):
The operators <, >, ==, >=, <=, an...
What is the correct syntax of ng-include?
...oting, it is important to know that ng-include requires the url path to be from the app root directory and not from the same directory where the partial.html lives. (whereas partial.html is the view file that the inline ng-include markup tag can be found).
For example:
Correct:
div ng-includ...
Why are Standard iterator ranges [begin, end) instead of [begin, end]?
... begin i end
and you immediately see that the range of elements from begin to i contains the elements A and B while the range of elements from i to end contains the elements C and D. Dereferencing i gives the element right of it, that is the first element of the second sequence.
Even the...
Saving images in Python at a very high quality
... elevation_angle is a number (in degrees) specifying the polar angle (down from vertical z axis) and the azimuthal_angle specifies the azimuthal angle (around the z axis).
I find that it is easiest to determine these values by first plotting the image and then rotating it and watching the current v...
