How do I calculate a point on a circle’s circumference?
...
The parametric equation for a circle is
m>x m> = cm>x m> + r * cos(a)
y = cy + r * sin(a)
Where r is the radius, cm>x m>,cy the origin, and a the angle.
That's pretty easy to adapt into any language with basic trig functions. Note that most languages will use radians for the a...
Order discrete m>x m> scale by frequency/value
I am making a dodged bar chart using ggplot with discrete m>x m> scale, the m>x m> am>x m>is are now arranged in alphabetical order, but I need to rearrange it so that it is ordered by the value of the y-am>x m>is (i.e., the tallest bar will be positioned on the left).

This is part of the collection initializer syntam>x m> in .NET. You can use this syntam>x m> on any collection you create as long as:
It implements IEnumerable (preferably IEnumerable<T>)
It has a method named Add(...)
What happens is the default constructor is called, an...
Sorting Python list based on the length of the string
...n an integer, not a boolean. So your code should instead read as follows:
m>x m>s.sort(lambda m>x m>,y: cmp(len(m>x m>), len(y)))
Note that cmp is a builtin function such that cmp(m>x m>, y) returns -1 if m>x m> is less than y, 0 if m>x m> is equal to y, and 1 if m>x m> is greater than y.
Of course, you can instead use the key para...

Can I keep Nuget on the jQuery 1.9.m>x m>/1.m>x m> path (instead of upgrading to 2.m>x m>)?
