Update on January 23, 2010: Thrifty 404 is not related to the Fast 404 project. Thrifty 404 is designed to handle missing or relocated content while Fast 404 is designed to handle 404s for arbitrary files (discussed at #76824: Drupal should not handle 404 for certain files).
This utility module replaces the standard "Page not found" page with one that includes a search form populated with search terms taken from the URL. It's designed as a thrifty replacement for the Search 404 module on sites that are experiencing high load from repeated 404 errors (and the expensive search queries that Search 404 automatically runs on each page load).

This modules allows for the creation of two dimensional (2D) QR barcodes.
QR codes are a popular type of two-dimensional barcode. They are also known as hardlinks or physical world hyperlinks. QR Codes store up to 4,296 alphanumeric characters of arbitrary text. This text can be anything, for example URL, contact information, a telephone number, even a poem! QR codes can be read by an optical device with the appropriate software. Such devices range from dedicated QR code readers to mobile phones.
QR Codes has an open, pluggable, architecture allowing administrators to decide what encoding engine they want to use for barcode image generation. Currently the module implements 3 engines as sub modules:
