File I/O
by greut, 1 comment
This document describes an interface for an abstract File I/O interface where web applications can interact with a file system, without any prior knowledge about the underlying filesystem. This interface can be used for e.g. an image preview before submitting a form or for saving a drawing from a canvas painting web application locally.

Algorithm Ink | Aza Raskin
by Xavier Lacot
Algorithm Ink is a port and extension of Context Free by Aza Raskin. The original grammar was originally conceived of by Chris Coyne. Algorithm Ink uses open-web, standards-based tools: no plugins required. You can even right-click to save the drawings. The caveat is that Firefox 3, and Opera 9.5 are the only browsers to fully support Canvas, so it may run slower on Safari, and not at all in Internet Explorer.
