LabVIEW and other programming notes, code snippets and utilities.

• Scale 8bit picture to quarter size.vi
  Scale picture to 1/4 size using a simple for loop. Very handy when you do not have NI VISION and handle video etc images using the build-in picture functions.
• ISO 8601 date and time.vi
  Returns current date and time as string in the ISO 8601 format, for example "2008-01-09T11:57:56".
• Update single key in INI file safe.vi
  Ever found that updating INI file using built-in LabVIEW functions wipes out any comments you have made in the file? I did, and here is a solution.
• mswd.vi
  Mean Square Weighted Devidiant.

To backup to a network volume, open Terminal and type (on 1 line):

  defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Then you'll be able to see mounted network drives in the Time Machine!
Beware that for total system recovery, when you boot from an OS X install DVD, the line above will fail as you cannot override the preferences on the DVD. My solution would be to install the OS from the DVD, then change the preference, then connect to the network drive and recover your data.
