Hi everyone,
We'd like to announce a beta of the new version of the Sage cell server.
We've set it up at:
aleph2.sagemath.org
It uses websockets (via SockJS, so it falls back to older techniques if
the browser doesn't support websockets) and has been pretty much
completely rewritten to use much more of the new IPython framework.
While hopefully the only changes from aleph you'll notice are that it is
more responsive (something like 25-50% faster for updates on interacts,
it feels like), it also lays the groundwork for interactive javascript
controls and other features we've wanted for a long time.
So please, test it out: aleph2.sagemath.org (if you've embedded aleph in
any webpages, you should be able to just change the address to
aleph2.sagemath.org). Sometime soon, we'll switch aleph.sagemath.org
over to the new version. If you find an issue with aleph2, please let
us know.
Volker and Ivan (and others interested in clients other than our
provided web client): are there libraries on Android and iOS that let
you use websockets naturally, instead of the polling model in aleph
version 1? I found
http://stackoverflow.com/questions/4501121/websockets-client-for-objective-c-preferrably-ios-compatible
and
http://stackoverflow.com/questions/6347499/websocket-library-for-android-ios-and-flash
that seem to indicate that you can incorporate websockets into an app:
SocketRocket for iOS:

Autobahn for Android: http://autobahn.ws/android
A huge thanks to Ira Hanson, Steven Johnson, and Alex Kramer who worked
tirelessly on this during the summer. And also a huge shoutout to the
IPython team for the great foundation we were able to build on.
We aren't quite ready for a final release. I'll be packaging things up
better over the next month or two.
Thanks,
Jason
