Some miscellaneous useful software.

“Forget” your PDF password: use open-source PDFCrack. Installs easily on Mac command line (use gmake).

Looking for high-quality maps and “satellite” imagery of Hamilton? Try Map.Hamilton’s iMapper. The interface takes a few minutes of experimentation to figure out, and then it’s cool. Make sure you switch to Aerial Viewer (latest year) to get their ground imagery, which I think is actually generated by airplanes. It’s quite a bit higher resolution than Google Earth has.

Want to annotate your PDF files? Try Skim. Seems potentially easier than using OmniGraffle… (and cheaper…)
