Google Wave: Tell me what it's good for

[kpreid]

I'm on Google Wave (by way of my participation in GSoC 2009). Tell me what's worth my time to do with it.

My ID is apparently kpreid.switchb.org@googlewave.com. (kpreid was taken, hmph.)

Since I can't do it, you should make a Go playing application!

Hm. I don't know whether that's possible directly on the Wave platform, but I saw they allow embedding 'gadgets', which might eventually support Caja and therefore Caja-CapTP and I could build a Go application on that and it would make a good simple demo...

I was wondering if Wave could serve for some kind of collaborative programming environment using Caja -- I haven't read their docs though. (Imagine someone's written an 'active essay': a literate program that does some kind of simulation, say. And you and your friends read it actively, trying things out, changing the code and seeing how that changes the behavior.)

Wave does support Caja-using OpenSocial gadgets; I just tried it with a gadget like the Caja example (http://code.google.com/p/google-caja/wiki/GettingStarted), hosted at my domain, and it worked. There doesn't seem to be any way to see the gadget URL and I don't know that there's any interaction with the rest of the wave, though.

Great.

I've been learning Javascript lately but haven't got around to Caja yet. (My first Javascript program, whee: http://wry.me/toys/palindromedary/ )

1. Action refers to this page, so hitting return isn't a 404.
2. Stray /div tag.
3. No need to use anything but IDs.
4. No specific delay is needed; the important thing is doing things after this event's handling has finished.
5. This helps respond to the delete key (using keydown) as well as responding at least after blur if non-keyboard-based input is used. (I haven't found a way to respond to all modifications immediately.)

Thank you!

[asviraspossible.livejournal.com]

Give me an invitation :)

[kpreid.livejournal.com]

Hah. Having any to give out is not automatic and I don't know what the schedule is.

[kpreid.livejournal.com]

I've got invitations to give out now, but I see (http://asviraspossible.livejournal.com/2009/10/31/) that you found one already.

[asviraspossible.livejournal.com]

Yeah, thanx. I have 18 invitations left :)
