Details for iPhone web app development (UPDATED)

Submitted by on

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.

button_to HTML options not completely intuitive

Submitted by on

While working on a site in Rails tonight I was adding a button_to that I wanted a JS confirmation requester. Well, based on my albeit beginner knowledge of Rails I thought the following would work:
[source:ruby]
< %= button_to "Empty Cart", :action => :empty, :confirm => "Really empty your cart?" %>
[/source]

Programming for kids, and older kids

One fault that could be levied at the computer industry is that they've lost a lot of the out-of-the-box creativity experience from the early days, back in the 80's when every computer you bought came out of the box with a programming language that anyone (with a manual or two) could start writing their own Hello World apps. Back then most people didn't learn to program at college, they learned from their $200 home computers.
