Convert jmol file to png

Simple note, from time to time I am looking for command which convert my xyz file into png. Here is the command:

C="connect delete; rotate y 15; rotate x 20; spacefill 80; background white; zoom 110;"
for f in *.jmol; do echo "${f}"; echo "$C write $f.png; exit" | jmol -nL "${f}" -s - ; done 

First line set up config, in this case we disable bonds, rotate in y-plane an about 15 degree and in x-plane 20 degree, set background to white, zoom molecule and set size of atoms to 80%;

Remote PDB and Django

Recently I have had to debug some error in Django system. In fact the problem was somewhere inside views and the debug page did not give any important information (as usually) and randomly show different place in .py files where exception was raised. I could not put standard pdb debugger, cause the problem  appeared only on nginx+uwsgi setup. I could not reproduce it on internal django webserver.
How to put debugger in uwsgi environment? Of course we do not have access to terminal in that case but we can use remote debugger. I have found very small and simply debugger rpdb:
http://tamentis.com/projects/rpdb/ 
Simply install it by pip and then put in the code:

import rpdb; rpdb.set_trace()

By default, rpdb listen on 4444 port so the next step is to connect to it by e.g. nc:

$ nc zuzia 4444

[teodor@zuzia production]$ nc zuzia 4444
