Which remote desktop solution is easiest and fastest to set up for users?
I want to add the possibility to start a remote desktop session from a TwoToReal discussion. The most obvious way would be to add a button somewhere that allows the asker to initiate the session and send the information regarding IP, etc. to the other answerers. This would be send directly to them in some form of e.g. a `vnc://` or similar link. This brings up several questions: 1. Has anyone experience with this? 2. Which application should be supported? [UltraVNC][1]? [TeamViewer][2]? [NoMachine][3]? There is a [comparison][4], but it does not tell about how aspects like how easy it is to install, use, etc. [1]: http://en.wikipedia.org/wiki/UltraVNC [2]: http://en.wikipedia.org/wiki/TeamViewer [3]: http://en.wikipedia.org/wiki/NX_technology [4]: http://en.wikipedia.org/wiki/Comparison_of_remote_desktop_software

How can I tell pylint to accept my Django imports?
I know there is [django-lint][1], which does linting for Django apps. However, I am using some of the ORM classes inside another app, which is not a full Django app. For that to work, I have the following three lines in my Python file: import settings from django.core.management import setup_environ setup_environ(settings) Running pylint over that file gives jabber_listener.py:3: [F] Unable to import 'settings' jabber_listener.py:5: [F] Unable to import 'django.core.management' jabber_listener.py:39: [F] Unable to import 'django.utils.encoding' jabber_listener.py:40: [F] Unable to import 'django.core.urlresolvers' jabber_listener.py:41: [F] Unable to import 'django.contrib.sessions.models' jabber_listener.py:42: [F] Unable to import 'django.contrib.auth.models' jabber_listener.py:44: [F] Unable to import 'accounts.models' As pylint does not execute the script, it obviously does not get the Python paths right. Any idea, how I can now tell pylint to set it up correctly? [1]: http://nschum.de/src/emacs/company-mode/

Is there a library for Skype to be used in Python/C?
For TwoToReal we use Jabber/XMPP to pull in experts in real-time whenever a user has a new question. This works fine but has also some limitations. We would like to also be able to access experts through Skype -- so far only [Skype4Py][1] allows that. It has, however, serious drawbacks as it requires a running Skype GUI and is limited to one Skype instance per machine. So, is there some backend support or library available that scales? It would be nice to have Skype support e.g. in [spectrum.im][2], which is a multi-transport library for Jabber/XMPP. [1]: http://sourceforge.net/projects/skype4py/ [2]: http://spectrum.im
