Security risk? When one tries to create an account the html for the challenge is just text, ascii of the html. So that is not so good, though I don't know if it's related to your changes or not. -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Otherwise, how do you use a backend different from GLPK? I think something like "from_file=..." argument in MixedIntegerLinearProgram() should be implemented, and it ought to be compatible with "solver=...". Behind the curtains it can talk to GLPK, no problem... Dima > > Nathann > -- You received this message because you are subscribed to the Google Groups "sage-support" group.

It asked me for sage0's password, though I did not think it had one. I tried with oscarlazo's password which has root powers, but that didn't work either. oscarlazo@VIDEO-AF:~$ sudo -u sageserver ssh sage0@localhost echo Done sage0@localhost's password: Permission denied, please try again. sage0@localhost's password: Permission denied, please try again. sage0@localhost's password: Permission denied (publickey,password). How could the sage0, sage1,... passwords be changed? Thank you! Oscar -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Reasons: The main part of the spkg was created in Jena, my main co-worker is professor in Jena, and our computational results in human-readable form are available in Jena anyway. So, I guess the sources of the spkg will go to github (to finally convert it to the new spkg format), the data and documentation will be in Jena, and the main author will be in Cologne... > I could host the files fine at UW now -- the issues are resolved.
