[sage-edu] sage in the clouds!
I just signed up for an account at http://cloud.sagemath.org and like what I see! Amazing job, guys, keep it up! I have 2 questions: (1) I had a heck of a time creating an account as the server did not like my password. I can see my students wasting class time with this. Any way this could be changed? (2) I currently use a server where I publish my worksheets to share with my students. I don't see this option in the cloud. Can one do the same in the cloud version? TIA, A.

SMC uses the password strength library, from Dropbox: https://tech.dropbox.com/2012/04/zxcvbn-realistic-password-strength-estimation/ Right now SMC is somewhat permissive allowing anything but "Very weak" passwords when creating an account; anything listed as very weak could trivially be cracked using a dictionary attack (the dropbox checker uses a dictionary of the top most common n-thousand weak passwords). I don't know what passwords you were trying, but I strongly encourage you to switch to a better system for choosing passwords for all your accounts (not just SMC), or maybe just use something like https://lastpass.com/. I don't want anybody to use SMC if they can't choose a password that isn't "very weak". If anything, I will probably change the password strength requirement in the other direction to require stronger passwords, rather than allowing weaker ones. (Of course I do have countermeasures in place to make an external dictionary attack very, very slow; however, if anybody ever got the password hash database, I want their work to be difficult. The passwords are hashed with 1000 iterations of Sha-512, in case anyone is interested.) > (2) I currently use a server where I publish my worksheets to share with my > students.

You would then add all your students as collaborators on the project. You can do this by clicking the settings "wrench" icon in a project, then pasting in a comma-separated list of email addresses next to "Collaborators" and clicking the button. When those people join SMC, they will automatically also see that project. You can put worksheets there for them to use. Moreover, as they use them, you can open them at the same time, see their cursors moving around, use the chat on the right, and if you are both using Google Chrome, you can type sage_chat() in a cell to get a video chat (very new feature). -- William > > TIA, > A.

Re: [sage-edu] sage in the clouds!
I had a hard time coming up with a passwd that was not so complicated that I could not remember it ever again! I use DropBox and had no problems there. The collaboration and chat features are nice. What if I want to share a worksheet on my blog? Sincerely, A.

If you forget your password there is a password reset option, which does work (unlike with sagenb.org, say). > I use DropBox and had no problems there. Dropbox itself has a password strength checker but they make *no requirements at all* about the password they let you use (their strength checker is only for your info). They also only require you to type your password once when you make your account, and don't validate your email address. Basically they got rid of all the standard "best practices" for account creation in order to absolutely minimize friction for people when signing up. In fact, I just created two random working Dropbox accounts while writing this paragraph (with random email address and bad password), to verify that the statements in it are true.Maybe Dropbox did this in order to maximize the "number of accounts" metric when trying to get investors (I don't know). Dropbox is surprisingly (to me) cavalier about security, given the nature of what they provide (for which security should be a big deal). > The collaboration and chat features are nice.

This is not *yet* implemented (SMC is very new still).The best you can do is print it to a pdf, and share that pdf, and also provide a link to the sagews file (which you can download and post somewhere, e.g., github). > > Sincerely, > A.

I should add that it is unclear if/when this sort of public sharing of user content will ever happen with SageMathCloud while it is part of University of Washington. There are very significant legal and other issues that are difficult to address. This is why publishing is turned off for sagenb.org. That said, the plan is that SageMathCloud will be spun off as a startup separate from the university if people are sufficiently interested in it (especially in premium accounts). -- William -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
