Free backup app - Genie Games Backup

Despite its name, Genie Games Backup is a general purpose backup utility for Windows that lets you make backups of any files you want, and run the backup either manually or on an automatic schedule.

As it turned out this wouldn't work, it kept adding "?confirm=Really empty your cart?" to the URL instead of doing a popup. A bit of fiddling later I realized that to work correctly the additional arguments to button_to need to be arrays, e.g.:

Details for iPhone web app development (UPDATED)

Some details have been made available by The University of Washington on how to develop web applications for iPhone - lots of basics in there, like keeping a good separation of HTML and CSS, but also some specifics on e.g. the screen width, some limitations in place, etc. Mandatory reading for anyone doing iPhone apps.

UPDATE: Apparently someone didn't like the info being posted publically, so someone posted a copy of the iPhone details elsewhere.
