When will those instances be available to be used as nodes in AWS EMR Clusters?

And yet, Microsoft Image Viewer still ignores EXIF image orientation metadata...

Oh! By the way, the site says "(This release contains support for new cameras such as the Canon EOS 5D, Nikon D50, D70s, and others.)"

Nikon D50, Canon EOS5D are not exactly "new"!

Re: Brierwood Design: So you wanna' build an analog RF simulator? Part I

This paper has two approaches I was thinking of:

1) Polymorphic numerical integration, to which one pass a function and the limits
2) Accumulating arrays.

One of the ideas I was tinkering the last couple of hours was to create a array of functions, so I can evaluate the entire array each time step. Resistors would be constant functions, capacitors and inductors would be transformations from the branch voltage and time to impedances.

I am just playing with the thought, but I may try somethinfg later this weekend. Unfortunately I work with enterprise IT architecture and as so I only get weekends to Haskell...

Funny! I was looking for someone implementing circuit simulation using Haskell!

Modified nodal analysis depends heavily on matrix inversions, and I am not sure this is the best "functional" approach.

What I really would like to check is whether it is possible to represent the branches by functions and then implement some kind of numeric integration directly over the circuit equations. In my point of view this would be the nirvana of circuit simulation!
