Vulnerability discussion

Use secure virtual memory. The system’s virtual memory swap file stores inactive physical memory contents, freeing physical memory. By default on some systems, the swap file is unencrypted. This file can contain confidential data, such as documents and passwords. Using secure virtual memory will secure the swap file at a cost of slightly slower speed (because Mac OS X must encrypt and decrypt the secure swap file).

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
