Re: [sage-devel] Trac vs Wiki passwords
trac and wiki accounts used to be linked (same username, same password). I changed my password on trac and it worked, but i can not use it on the wiki. Unfortunately, i am travelling and i do not have access to my previous password. How are the two system currently related ? Not at all. You can't currently change your wiki password. Basically through a series of hacks, we had hooked the wiki's authentication up to trac, but I think that broke when the wiki was moved off of boxen last summer. Oh, was that heavily advertised? I think we probably still have quite a bit of documentation that says both have the same password... On a slight tangent: I personally don't care for our current wiki, MediaWiki -- it has caused us numerous issues over the years (e.g. memory hog on boxen), and is a bit of a pain to administer. I'm not really aware of any modern wiki platforms (other than gollum, which didn't handle large wikis like ours when I checked it out 1.5 years ago), but if anyone has any thoughts on the matter I would be happy to discuss it (maybe in a different thread). I don't know that moving all that content/links would be worth the effort. -- You received this message because you are subscribed to the Google Groups sage-devel group.

Re: [sage-devel] Re: questions about option: inplace vs copy
Is there a convention for functions returning larger objects? For example if M is an immutable matrix, would it give more speed to have something like M.__mul__(M, immutable=True)? -- Jori Mäntysalo

Speed? I don't know, this is a real question. I just thinked about difference between matrices, graphs and posets. For matrices we have the set_immutable() function. Posets are always immutable. Graphs can be made immutable at creation time, and a copy() can return a mutable graph from immutable (or immutable from mutable). Would we gain anything if - for example - cartesian_product() would have a immutable-option? -- Jori Mäntysalo
