Open-source fractal maps
I'm interested in creating a game that uses fractal maps for more realistic geography. However, the only fractal map programs I have found are Windows-only, for example Fractal Mapper.

How do you compile OpenSSL for x64?
After following the instructions in INSTALL.W64 I have two problems: The code is still written to the "out32" folder. I need to be able to link to both 32-bit and 64-bit versions of the library on my workstation, so I don't want the 64-bit versions to clobber the 32-bit libs. The output is still 32-bit! This means that I get "unresolve...

Marshal C++ "string" class in C# P/Invoke
I have a function in a native DLL defined as follows: #include <string> void SetPath(string path); I tried to put this in Microsoft's P/Invoke Interop Assistant, but it chokes on the "string" class (which I think is from MFC?). I have tried marshaling it as a variety of different types (C# String, char[], byte[]) but every time I eit...

RAII vs. exceptions
The more we use RAII in C++, the more we find ourselves with destructors that do non-trivial deallocation. Now, deallocation (finalization, however you want to call it) can fail, in which case exceptions are really the only way to let anybody upstairs know of our deallocation problem. But then again, throwing-destructors are a bad idea b...
