Update: This has moved to my portfolio.

This is an example of a dynamic form which serves as an email builder. It is a genericized version of one I wrote for my employer.

It uses jQuery and jQuery Cookie and works in Safari and Firefox. It was last updated on 2008 May 14 to fix Firefox compatibility.

This is an example of my attempt to separate HTML, CSS, and JS into separate sections. Note that for simplicity purposes the document is one HTML file.

Interruptible link-dest Backup Solution

I was inspired by Time Machine for every Unix out there to use the link-dest technique for backing up one external disk to another, however I found some limitations in its implementation, so I modified the script.

  1. Moved Source and Destination into variables.
  2. Added a Progress directory so the script can be interrupted and resumed.
  3. Added an exclude file to the Source directory so that the External disk’s special folders (Spotlight, etc) are not copied.
  4. Added the -E flag to rsync so it copies Extended Attributes on Mac OS X (remove if you are not using Mac OS X).
  5. Added the -x flag to rsync so it does not span disks.
  6. Added the –delete flag to rsync so if rsync fails upon re-running the script files deleted from the source are deleted from the Progress directory.
  7. Modified the Date format to mimic Time Machine’s.
  8. Modified the Destination so that it directly uses it rather than a subdirectory.
  9. Modified the symbolic link command so it removes the old Latest link and creates the new one in one step.
  10. Use && to ensure commands don’t occur if rsync fails.

The script (Updated to fix bug):

#!/bin/sh

source="/Volumes/Gray"
destination="/Volumes/Gray Backup"

mkdir -p "$destination/Progress"
rsync -aPEx --delete --exclude-from="$source/.exclude" \
            --link-dest="$destination/Latest" \
            "$source" "$destination/Progress" \
    && date=`date "+%Y-%m-%d-%H%M%S"` \
    && mv "$destination/Progress" "$destination/$date" \
    && ln -sfh "$date" "$destination/Latest"
