Okay, back to the agenda, ladies. I think I said, this thread is about usability.
Regardless of the fact that pyjamas v0.x could be faster with all developers following the DEVELOPER.RULES there will always be a potential necessity to present some indicators upon startup, because we have a weak link between the loading index.html (blank by default) and the boostrap JavaScript file that provides the actual application. Whatever type of failure occurs, it's necessary to provide some feedack that an operation is going on and takes some time. Just in general, not directly related to the pyjs startup, I think it's good to review the "Response Times: The 3 Important Limits" [1] by Jakob Nielsen once again. [1] http://www.useit.com/papers/responsetime.html In accordance to the DEVELOPER.RULES I announce that I will now come up with a suggestion of an "Ajax spinner" on the pyjs.org website, and push the changes to repository at SF. I have looked at the options online, looks like we can only use a GIF file for the actual spinner, because Animated PNG and pure CSS animation is not supported by all major browsers yet. Here are some of the resources I looked at: a) http://www.ajaxload.info (generates Ajax loaders in GIF format) b) http://preloaders.net (generates Ajax loaders in GIF an APNG) c) http://cssload.net (generates Ajax loaders in CSS3) d) http://www.netwaver.com/21/8-ajax-loading-icon-generators/ (an article from 2009 mentioning even more options) I hope it's okay that I take a generated binary (i.e. a GIF file) and document the source where I took it from (e.g. ajaxload.info). I cannot see any license concerns that this brings with it. Any objections? Peter
