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.

.SYNOPSIS
  Time-base One-Time Password Algorithm (RFC 6238)

.DESCRIPTION
  This is an implementation of the RFC 6238 Time-Based One-Time Password Algorithm draft based upon the HMAC-based One-Time Password (HOTP) algorithm (RFC 4226). This is a time based variant of the HOTP algorithm providing short-lived OTP values.

-- cd to the current finder window folder in iTerm. Or drag a folder onto this script to cd to that folder in iTerm.
-- found this script in the comments of this article: http://www.macosxhints.com/article.php?story=20050924210643297

-- Instructions for use:
-- paste this script into Script Editor and save as an application to ~/Library/Scripts/Applications/Finder/cd to in iTerm
-- run via the AppleScript Menu item (http://www.apple.com/applescript/scriptmenu/)
-- Or better yet, Control-click and drag it to the top of a finder window so it appears in every finder window.
-- Activate it by clicking on it or dragging a folder onto it.

-- Another nice touch is to give the saved script the same icon as iTerm.
