Ouch, I see. We'd need at least two pools of kernels, rather than one in that case. A big advantage would be that it allows us to switch default and still have the other method available (if people can find the language switch). For that reason, I would think it might lead to a slightly smoother transition for cases where people have developed pages with cells embedded (which is what I usually do if I use sagecell in a class demo): language switching can be done on the page itself (provided one hasn't stripped away the language selector, which I realize I have usually done :-(). Changing the server definitely requires editing the HTML page, so that is never going to happen in the class room. The one thing that might save you there is the "share" button that comes with the (at this moment probably "error") output, where repointing the URL might be an option. I think it's worth considering if investing in having a py2 pool as well as a py3 pool of kernels available will help transition sufficiently to justify the cost. For me personally: I'm now on alert that I should always check sagecell demos before taking them to class. Whatever we do, we should make sure that there's a stable way of doing something over any semester-long period (and make it easy to find how to do that!). Tripping up people between their lecture prep and their lecture performance is just evil. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
