Ternary operation in CoffeeScript
...ffeescript doesn't support javascript ternary operator.
Here is the reason from the coffeescript author:

When should I use Kruskal as opposed to Prim (and vice versa)?
...m.co.uk/showthread.php?t=232168.
Kruskal's algorithm will grow a solution from the cheapest edge by adding the next cheapest edge, provided that it doesn't create a cycle.
Prim's algorithm will grow a solution from a random vertex by adding the next cheapest vertex, the vertex that is not current...
When should I use double instead of decimal?
...850
Decimal: 600000.0000000000
As you can see, even though we are adding from the same source constant, the results of the double is less precise (although probably will round correctly), and the float is far less precise, to the point where it has been reduced to only two significant digits.

Pythonic way to print list items
...int(*myList, sep='\n')
You can get the same behavior on Python 2.x using from __future__ import print_function, as noted by mgilson in comments.
With the print statement on Python 2.x you will need iteration of some kind, regarding your question about print(p) for p in myList not working, you can...

Negative weights using Dijkstra's Algorithm
...neral. For example, consider this graph:
Assume the edges are directed from left to right as in your example,
Your algorithm will work as follows:
First, you set d(A) to zero and the other distances to infinity.
You then expand out node A, setting d(B) to 1, d(C) to zero, and d(D) to 99.

Why should I use the keyword “final” on a method parameter in Java?
... Use the keyword final when you want the compiler to prevent a
variable from being re-assigned to a different object.
Whether the variable is a static variable, member variable, local variable, or argument/parameter variable, the effect is entirely the same.
Example
Let’s see the effect in ...
