I own the sagenb.org hardware, and manage the servers, and here's what I think about how they should be used. Use of http://sagenb.org should be mainly for experimental use, and not something anybody should rely on. I make no stated -- even attempted -- guarantees about backups, privacy, security, stability, uptime, etc. That said, the wheels are in motion to start an off-campus service called "http://sagenb.com"; (which will initially contain a clone of http://sagenb.org), for which I will want to encourage as wide of usage as possible. It will generate revenue that will go toward supporting Sage development. -- William > > John > > On 7 February 2012 17:42, Jason Grout <[email protected]> wrote: >> On 2/7/12 11:09 AM, Gwyn wrote: >>> >>> A second problem I've encountered trying to use sage for this class: >>> >>> Initially, after I'd created a Sage notebook account, if I logged out >>> for more than (around) an hour and tried to log back in, I would >>> receive a message: >>> >>> "Username does not exist." >>> >>> I created the same username a second time with the same password and >>> signed in -- and my worksheets were all saved and fine. >>> >>> This lasted for about a week and a half, where every time I was signed >>> out, the server seemed to "forget" my username.
