Source code (coming soon) of some of my smaller software experiments:
- MailHeaderDump -- collects attributes of mail messages that reside in a user's server-based message store for later analysis. Used as a data collection tool in a study of e-mail behavior. (Pure Java with JNLP, 2006)
- AB2StarTAC -- dumps Mac OS X Address Book in StarTalk format, for downloading to StarTAC mobile phone (Java Mac OS X Tool, 2003)
- MakeIndex -- Submits a file to the Mac OS X FBC (Find by Content) indexer. (Java Mac OS X Tool, 2003)
- AvTest -- Aviation test Web app., as running on flyjohn.com (WebObjects Java App., 2003)
- MimeTypes -- Dumps a list of what LaunchServices thinks are the types ("kind string") and application for a certain list of MIME types & extensions. This is not a friendly tool, but it's an example of asking LaunchService these questions. Will be obsoleted by UTIs in 10.5. (Java Mac OS X Tool, 2003)
- filecmp -- compares two Mac OS 9 Extensions Manager "Save as" text output and flags changes. Useful to know how a system was modified over time. Pretty much moot now. (Pure Java, 199x)

Older content being converted to the new structure:
Politics: Review the U.S. Declaration of Independence. It has an excellent summary of the purpose of government (paragraph 2). One that we need to remember and start applying again.
Privacy: A suggested privacy instruction to send vendors, and a list of actions to protect your privacy.
