// bit_cast<Dest,Source> is a template function that implements the

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Working around offsetof limitations in C++

Working around offsetof limitations in C++:

There is sometimes a situation in which one needs to get the relative offset of a structure field, common examples of this include serialization frameworks which aid to serialize objects, vertex attributes for rendering (D3D, GL.), etc.

The most common technique for getting this information is through the offsetof macro defined in stddef.h. Unfortunately using the macro in C++ comes with a new set of restrictions that prevent some (subjectively valid) uses of it.

Source indexing for github projects

Symbol Servers

I'm assuming you are familiar with symbol servers - you might not have one set up yourself for your own projects, but you probably use Microsoft's public symbol server for downloading symbols for system DLLs.

For your own projects it might be useful to set up a symbol server - I won't go into how you do that here since it's well documented elsewhere, but basically you just set up a folder somewhere - say X:\symbols\ or \servername\symbols or even http://servername.foo/symbols/ which has a defined tree structure:

symbols/
symbols/mymodule.pdb/
symbols/mymodule.pdb/123456789012345678901234567890122/
