For Ubuntu, oracle-java (7/8) installed. It'll be at this location /usr/lib/jvm and sudo access is required.
Create the file /etc/ld.so.conf.d/java.conf with the following entries:
/usr/lib/jvm/java-8-oracle/jre/lib/amd64
/usr/lib/jvm/java-8-oracle/jre/lib/amd64/server
Just source the virtualenvwrapper.sh script in your script to import the virtualenvwrapper's functions. You should then be able to use the workon function in your script.
And maybe better, you could create a shell script (you could name it venv-run.sh for example) to run any Python script into a given virtualenv, and place it in /usr/bin, /usr/local/bin, or any directory which is in your PATH.
Such a script could look like this:
# if virtualenvwrapper.sh is in your PATH (i.e. installed with pip)
source `which virtualenvwrapper.sh`
#source /path/to/virtualenvwrapper.sh # if it's not in your PATH

Convert UNIX timestamp to date in LibreOffice Calc
As it seems, OpenOffice's "day 0" is December 12th, 1899; that implies that January 1st, 1970 is day 25569 for OpenOffice. Now, if you divide a UNIX timestamp by 86400 (the number of seconds in a normal day), that will give you the number of days between the epoch and that timestamp (and some decimal, that you can use to calculate the time of day). And if you sum that number with 25569, you have an OpenOffice day for that timestamp.
Alright, let's put all the pieces together: let's say cell A2 contains a UNIX timestamp 1341104400, then this formula
=A2/86400+25569
will return a number. And if you format that cell as a date, DD/MM/YYYY HH:MM:SS, then you'll read a pretty "01/07/2012 01:00:00" there.
