I have reworked the code a bit and added some simple synchronization, just to guarantee that the whole shared memory region is updated atomically.

What problems did you encounter? I have experience with c++ and the windows api, so I might be able to help

Essentially this adds a Module method (same as a class method aka a "static" method) called __add_one_arg_setter to the module.
For a real explanation of the class << self thing look at this old stackoverflow question:
m

The method does some metaprogramming. It takes a class and for every instance ...

I post this here as alternative method, more or less performat of other?

num = 5
a = &#91;2, 3, 4&#93;
a&#46;sort&#46;find{|x| x >= num} || a&#46;first # =>2


That will only work if the array is sorted. It will return the first element that's greater than num, not necessarily the closest ...

I would probably use min_by with the difference to the target number. It's O(n) and no temporary array.

There exist multiple methods for transforming continouus time circuits to discrete time.
See:
Impulse Invariance
Bilinear Transform
Matched Z-Transform

I also recommend this paper where another method called topology-preserving transform is introduced

I think opening a modern file dialog from within ruby is actually not possible.
You would need to call methods like SetOptions or Show through the function pointers in the IFileDialog VTable, and I don't think you can do this in ruby.
Reimplementing a file dialog in ruby would also be a huge task.
I ...

1) enum is a list of specific integer values that are accessed by their name
You can think of it that way, though it's not technically true. An enum value like D_Mon is of some enum type (in your example its an unnamed enum type), but it is guaranteed to be implicitely convertible to its ...

So you don't want a sample and hold? I'm not quite sure what you mean by this:

Can you explain a bit more what you want to achieve?

No, unfortunately not without using stage0. I don't think there's a way to type NaN in the code module, is there?
