WIP #1 Geosphere

I love tri-geospheres, Aren't they lovely?

KFold cross validation implementation in C++

While working with neuronal or bayesian network for diagnosis one of the most important thing you need to do is to choose correctly the trainning and the testing sets.

I've just made a little implementation of the K-fold cross validation technique in C++ because after looking for it I couldn't found anything on that language.

I hope it will be useful for you, you can find it here

Compiler options for small executables

Yesterday I installed VS 2008 to try to get my things working on it. It gaves me a lot of errors while trying to compile my introsystem but after a while I got it working

The problem on that point was that after generate the final .exe file, it didn't work with kkrunchy (from ryg) compressor giving me the following error:

- ERROR: files with exports or tls data are not supported

I started to go throw all the options of the compiler/link again and luckily I got it working.

Here you can see the options I've used. I just included the ones I've changed from the original template that VS generate for a simple Win32 project

You can grab the base project source from here
