PyCharm 3.4 Community Edition does not support Tfs Integration

PyCharm 3.4 Community is a very fine IDE and I cannot complain. But for some of the stuff that I do I need to use Tfs as source control. I spent quite a few hours searching the web how to enable Tfs integration in PyCharm but I can't find a good documentation that says you can't not use in PyCharm. But IntelliJ IDEA feature comparison matrix shows that Tfs Integration is only available in Ultimate.  So it must be the case that Tfs Integration is only available in Professional version or it just does not work.

Unable to mount VirtualBox shared drive using 4.3.10

When mounting a shared drive in VirtualBox 4.3.10, got he following error in Linux box:

sudo mount -t vboxsf E_DRIVE vbox
mount: wrong fs type, bad option, bad superblock on E_DRIVE,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

This is caused by wrong symbolic link, to fix it do:

~$ sudo ln -sf /usr/lib/i386-linux-gnu/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf
