• Plotting and Animating 2D points with 'headings'

  - by mellort

  I will have a set of data (x, y, heading), and I need to animate it in real-time. I am currently using matplotlib to animate (x, y) and it works fine, but I would really like to have some way to indicate heading, ie what direction the object is facing. What would be the best library for this? It seems like PyGame might be able to help me out, but would I have to roll out my own graphing library for it? Thanks

• how can you find out if an NSObject has a certain property?

  - by strawtarget

  Let's say in Apple API version 1.0, there is a class NSFoo with a property 'color'. API 1.1 adds property 'size'. I want to know whether I can use the getter: myFoo.size [myFoo respondsToSelector:@selector(getSize)] doesn't work as expected. What's the correct way to find out if an object has a property? Thanks!

• What's the reason I can't create generic array types in Java?

  - by devoured elysium

  What's the reason Java doesn't allow us to do private T[] elements = new T[initialCapacity]; ? I could understand .NET didn't allow us to do that, as in .NET you have value types that at run-time can have different sizes, but in Java all kinds of T will be object references, thus having the same size(correct me if I'm wrong). What is the reason?
