At the end of the [helpers] section in ~/.subversion/config add (tomado de http://brainvisa.info/repository.html)

editor-cmd = kate
diff-cmd = kompare_svn
diff3-cmd = kdiff3_svn
merge-tool-cmd = kdiff3_svn


Here kompare_svn is the script (base their mine merged)

#!/bin/sh
exec kompare "$6" "$7"

And kdiff3_svn is the script

#!/bin/sh

if [ "$#" != "3" ]; then
if [ "$#" != "4" ]; then
outfile=`mktemp`
res=0
# kdiff3 --L1 "$4" --L2 "$6" --L3 "$8" -out "${outfile}" "$9" "${10}" "${11}" && cat "${outfile}" || res=1
kdiff3 -out "${outfile}" "${10}" "${11}" "$9" && cat "${outfile}" || res=1
if [ -f "${outfile}" ]; then
rm -f "${outfile}"
fi
if [ -f "${outfile}.orig" ]; then
rm -f "${outfile}.orig"
fi
exit $res
fi
fi
if [ "$#" -gt 3 ]; then
exec kdiff3 -out "$4" "$1" "$2" "$3"
else
exec kdiff3 "$1" "$2" "$3"
fi


Alternativamente
#!/bin/sh
kdiff3 -m $1 $2 $3 -o $4 1>&2

Remember to make both scripts executable

Greek font in MAXIMA

Acquiring and installing a Greek font on your system is an important addition — it allows all those Greek characters, common in mathematical expressions, to be displayed properly. Here is a link to a free font:

SPIonic.ttf

For Windows systems, place this font in the directory \Windows\Fonts. For Linux, place it in /usr/share/fonts (there may be some distribution-dependent variations in this location). Next, for all platforms, run wxMaxima and go to the menu item "Edit ... Configure ... Style tab", select "Use Greek Font", then click the "Greek" button, navigate to and select the font you have just installed.

The change should take effect immediately. To test the ability of wxMaxima to render correctly, type examples of Greek characters in wxMaxima using this notation:

%Omega;
Ω
%omega;
ω

The results shown above indicate success. If your typed strings reappear in the output unchanged, something went wrong — go over the instructions above and repeat any steps you missed.

Thereafter activate this font in wxMaxima, from Edit>Configure>Style>Use greek font

dyndns.org

The following is an extension to https://www.dyndns.com/services/dns/dyndns/howto.html

In order to have a dynamic dns address, do the following:

- Open an account at http://www.dyndns.com/

- Now we have to install a client to update the ip address everytime we have a new IP address: in this case from synaptic I chose ddclient (see also http://www.dyndns.com/support/clients/ )
# sudo apt-get install ddclient

To configure ddclient, edit the file /etc/ddclient.conf and run
the tool in https://www.dyndns.com/support/tools/clientconfig.html
In the webpage of ddclient: http://ddclient.wiki.sourceforge.net/ you can learn how to configure it.
A tutorial for configuring ddclient in dyndns.org is https://www.dyndns.com/support/kb/using_ddclient_with_dyndns_services.html


Another tools for linux are
- ndyndns >> http://code.google.com/p/ndyndns/
- and the ones in https://www.dyndns.com/support/clients/unix.html


In order to check if ddclient is working...
$ nslookup earendil.dyndns.org
You can also try to go to
https://www.dyndns.com/support/tools/dnsquery.html
and in the field Query and Record Type: write down earendil.dyndns.org


OPEN THE PORTS IN THE ROUTER... PORT FORWARDING
http://portforward.com/
https://www.dyndns.com/support/kb/routers_and_port_forwarding.html

To see if you can access the computer from outside, check that the ports are open with https://www.dyndns.com/support/tools/openport.html


Finally, install OPENVPN ( https://www.dyndns.com/support/kb/using_openvpn_with_dyndns.html )
