Tag 4 – Erste Eindrücke von der Mexikanischen Arbeitswelt
Mehr Bilder gibt’s die Tage, am ersten Tag wollte ich mich noch etwas zurück halten…
Mein Vorstellungsgespräch bei einer mexikanischen IT-Firma findet um 17:00 Uhr im German Centre statt. Nach einer halben Stunde Taxi-Fahrt (daran kann man sich hier echt gewöhnen) bin ich von deutschen Logos umgeben. Passkontrolle und ab in den ersten Stock. Dann werde ich abwechselnd auf Englisch und Spanisch ausgequetscht. Macht Spaß. Ich hab den Job. Aber auch noch das Vorstellungsgespräch nächste Woche Dienstag abwarten und dann entscheiden. 😉
Abends gehen wir nochmal zum Teakwondo-Zentrum. Ab Mittwoch wird mittrainiert. Auf dem Weg zurück komme ich nicht umher mir Milch und Müsli zu kaufen. Ein bisschen Tradition muss sein. 🙂
Irgendwie ein anstrengender Tag, Jetlag noch immer nicht überwunden. 22:30 Uhr schlafen gehen. Gute Nacht.
La Habitacion Azul – Tag 3
Heute morgen sind wir umgezogen. Eine heikle Angelegenheit über die etwas wackelige und sehr schmale Wendeltreppe eine Etage nach oben. Der TÜV Rheinland ist nicht überall 😉
Jose, ein argentinischer Mexikaner, der mal in Spanien gearbeitet hat, zudem “BWL-Professor” ist, zeigt uns ein nettes mexikanisches Restaurant. Es gibt auch Sachen, die nicht scharf sind. Mein Glück. 🙂
Der zweite Tag
Mit dem Taxi zum Walmart: Bier und leckeres Essen besorgt. Dann zurück ins Hostel… Zum Abschluss noch ein paar Bilder:

Leckeres Essen aus dem Supermercado. |
Cerveza! |
Die Reise und Tag 1
Heute geht’s los!
IPython adds Web Interface to Python Programs or HowTo Run AICCM (ab initio Cyclic Cluster Model) from a Webbrowser
interface running in the browser, that connects to a running IPython Kernel. In principle, this adds a web interface to every Python program. To understand how amazing this is, just imagine how much it costs to develop a professional web interface for an application, called Notebooks. The only thing you need is the Tornado Web Server [2].
educational quantum chemical program written in Python with C extensions. It is developed by me and my colleagues in the group of Prof. Bredow at the Mulliken Center for Theoretical Chemistry at the University of Bonn. In the following HowTo it is assumed that AICCM is installed on your system. For download and installation instructions on AICCM please go to the AICCM website.
– If you haven’t already done so, you need to add lib/python to your PYTHONPATH.
To make this permanent, add this line to your .bashrc or .zshrc, depending on the shell you use.
2. Installation of IPython
– Get IPython 0.12
wget http://archive.ipython.org/release/0.12/ipython-0.12.tar.gz
– Install IPython
3. Start IPython with enabled web interface
ipython notebook
IPython starts a webbrowser displaying the dash board where all Notebooks are listed.
Click on new Notebook. A new window opens where you can enter your Python code.
4. Running a calculation
A minimal input for AICCM calculating the Hartree-Fock total energy of the Nitrogen molecule is:
import aiccm
molecule = ase.Atoms(‘2N’, [(0., 0., 0.), (0., 0., 1.1)])
calc_AICCM = aiccm.aseinterface.AICCM()
molecule.set_calculator(calc_AICCM)
e_molecule = molecule.get_potential_energy()
print ‘Total Energy: %5.2f Hartree’ % e_molecule
Copy and paste this into the shell into the browser. The code is executed by pressing CTRL+ENTER.
If the session is saved it appears in your IPython dashboard after you hit the reload button!
This is awesome! A big thanks to the developers of IPython!

Update to Ubuntu 11.10 breaks i386 applications (Crossover Office, Skype, etc)
The reason is that there are x86_64 packages for applications like Skype, Crossover Office, etc that are in reality for the i386 architecture. Ubuntu does not know how to resolve the dependencies.
One solution is to use the i386 packages and try to let Ubuntu resolve the dependencies.
The second solution, which is the one I tried is to enable multiarch. And this is how it is done:
echo foreign-architecture i386 | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch
Then install the required libraries for the i386 architecture:
sudo apt-get install libxss1:i386 libqtcore4:i386 libqt4-dbus:i386
Logitech MX1000 bluetooth mouse fails after system update
My good old bluetooth mouse “Logitech MX1000 Laser” stopped working after the last system upgrade to Ubuntu 11.10. I had this already after the last system upgrade and this time I decided to blog about it so it might help others.
The problem is, that the dongle switches to bluetooth mode and somehow the system does not manage to successfully pair it.
This is why it might be best to disable bluetooth for this mouse. Mine is very old, so I wonder if this is better for newer models.
If one gets tired of disabling bluetooth in the applet everytime with the help of a second mouse 😉 just do the following:
1. As root edit the file:
sudo vim /lib/udev/rules.d/62-bluez-hid2hci.rules
2. Find the lines:
# Logitech devices
KERNEL==”hiddev*”, ATTRS{idVendor}==”046d”, ATTRS{idProduct}==”c70[345abce]|c71[34bc]”,
RUN+=”hid2hci –method=logitech-hid –devpath=%p”
and change them into:
KERNEL==”hidraw*”, ATTRS{idVendor}==”046d”, ATTRS{idProduct}==”c70[345abce]|c71[34bc]”,
RUN+=”hid2hci –method=logitech-hid –devpath=%p”
Winner of the Nobel Prize in Physics 2011 Saul Paulmutter in Bonn
The American astrophycicist and winner of the Nobel Prize in Physics 2011 Saul Paulmutter visited Bonn as part of the collaboration ‘Supernova Factory’ in that
Prof. Marek Kowalski of the Institute of Physics in Bonn is being a part of.
He gave a stunning lecture in the overcrowded Wolfgang Paul Lecture Hall.
It was his first public lecture after receiving this outstanding award together with
Brian P. Schmidt and Adam G. Riess “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae”.
