It's so easy yet it took me quite a while to 'google' it out.

The problem: Being root you would like to resume another user's screen session. Let the user be A.

You 'become' him by

su A -

Then you would like to

screen -r

but unfortunately this gives you an error:

Cannot open your terminal '/dev/pts/0' - please check.

or something similar. The simple cause is that user A does not have the right to write into your (root's) terminal. This can be fixed by chmod'ing the above displayed file. For example:

chmod a+rwx /dev/pts/0

Do it as root and be aware that this is a severe security risk!

When you have e.g. an html file inside your repository and you want it to be displayed in your browers correctly, i.e. as html and not as plain text, this is what you need to do:

One needs to properly set the mime-type to "text/html".

Checkout the repository and do the following:

svn propedit svn:mime-type yourfile.html --editor-cmd vi

Here, vi is used as the editor.
enter "text/html", save and exit (:wq for vi)
Check if mime-type was changed

svn -R proplist

svn commit
