[sage-devel] Review ticket #13649
Hi, is anybody willing to review #13649<http://trac.sagemath.org/sage_trac/ticket/13649>? It consists of implementing two/three new methods which are actually aliases for existing methods, so it's quite easy to check if it's correct or not.

Re: [sage-devel] Sage-5.4 virtual appliance
I tried the new VM, it works well, except for a few things: - it would be nice to have some way for changing the keyboard layout for "the rest of us" who don't live in the US :P - Chrome complains about the IcedTea plugin being out of date 2012/11/21 Volker Braun > Google's v8 consistently beats other implementations by a wide margin. I'm not really sure there is such a great difference, especially in a "somehow limited" environment such a VM, but OK I was just curious. I have nothing against Chrome, but IMHO since Sage is a strongly FLOSS oriented project, we should warn users that they're about to download and use a proprietary browser if they use the virtual machine. Just for the sake of clarity. Anyway, if there's any way I can help to replace Chrome with Chromium in the VM I'm glad to "get my hands dirty". ;) BTW for the issue about being unable to use the host browser, isn't there any way to read the provided token that Sage outputs on the screen? Then maybe we could be able to alert the user with a message, or even better set up a mini web server with a PHP page, say [VM-IP]/access-sage.php that then could redirect the user to the localhost of the VM with the correct access token. What do you think about this idea? Or maybe there is a way to trick SageNb and generate always the same access token.

You say "This is not an option for the virtual machine, you can't start a host browser from within the VM." But actually, if you correctly set the XDG variables correctly, sage -notebookwill automatically start the browser for you. It will be even simpler because you don't need to have two different users... I can have a look if you help me to solve the looping issue. Also, can you clarify why you're running Chrome in the VM?

For the former, I think yes but haven't tried, for the latter I can assure you the installation is the standard Ubuntu way, so you can set up the first user account with the name that you want. You can pre-install any software package (or system file for that matter) and the DVD will contain it, so when you install the system you have what you need. > 3) allow adding of new sources.list.d files to the install target easily? > Absolutely yes. Apart from allowing you to chroot and then simply use "sudo add-apt-repository" you can also manually copy a file in that directory. If you need information about UCK feel free to contact me.

The only exception to this would be the Macbook Air without an external SuperDrive. BTW Nicolas is there a specific reason you're planning to use the "hackish and dirty" Remastersys instead of a pure Ubuntu editing tool like UCK?

[sage-devel] Building documentation fails on 5.4-rc2
Hi, I'm trying to upgrade from Sage 5.4 rc0 to rc2. A lot of stuff compiled fine, but then the installation failed when building documentation.

"my" students gave me a positive feedback in general even if there were those technical problems, so I think Sage is quite amazing if you show it in a good way (I personally simply had to translate/adapt the tutorial of "Learning Sage" by Paul Lutus, it's very good). I have to admit when I saw Sage at first in high school (3 years ago) I was scared by the web interface... but now that I tried it again it felt quite easy. I don't really know what has changed for me. :) I totally agree with the chat system, but IMHO for that to work you would also need to setup user "groups", something like Facebook has.

No, PPAs contain binaries and also the corresponding sources, you have to successfully build a package in order to upload it to the PPA for other people to download it.

But my humble question is: why should Sage risk to donate the hard work to companies such Apple (only an example) which use open source to make money without giving back?
