124. gnome-activity-journal and zeitgeist

It may not be advertised widely, but zeitgeist + journal might help save your behind when you're in a hurry and can't find a file.

aptitude show zeitgeist
" Zeitgeist is a service which logs the user's activities and events (files opened, websites visited, conversations held with other people, etc.) and makes the relevant information available to other applications."

And that it does. A service without an interface isn't terribly useful -- so you will want to install gnome-activity-journal as well.

Chances are that zeitgeist is already running on your system, so that you only need to install gnome-activity-journal, which is present in the repos, and then you'll get access to all the old data you've been accumulating.

123. Adding python support to nwchem under debian

I've posted the general build instructions for nwchem 6.0 with mpi support here: http://verahill.blogspot.com.au/2012/03/nwchem-60-with-openmpi-support-on.html

However, those instructions don't include python support.

0. Download,  extract nwchem and install blas etc. as shown in http://verahill.blogspot.com.au/2012/03/nwchem-60-with-openmpi-support-on.html

1. Edit nwchem-6.0/src/config/makefile.h
Change line 1962 from

EXTRA_LIBS +=    -lnwcutil  -lpthread -lutil -ldl

to

EXTRA_LIBS +=    -lnwcutil  -lpthread -lutil -ldl -lz -lssl

2. Install python headers
sudo apt-get install python2.7-dev

3. Execute the following commands (one by one or by putting them in a shell script)

export LARGE_FILES=TRUE
export TCGRSH=/usr/bin/ssh
export NWCHEM_TOP=`pwd`
export NWCHEM_TARGET=LINUX64
export NWCHEM_MODULES="all python"
export PYTHONHOME=/usr
export PYTHONVERSION=2.7
export USE_MPI=y
export USE_MPIF=y
export MPI_LOC=/usr/lib/openmpi/lib
export MPI_INCLUDE=/usr/lib/openmpi/include
export LIBRARY_PATH=$LIBRARY_PATH:/usr/lib/openmpi/lib
export LIBMPI="-lmpi -lopen-rte -lopen-pal -ldl -lmpi_f77 -lpthread"
cd $NWCHEM_TOP/src
make clean
make nwchem_config
make FC=gfortran

It should work fine and after a long build you'll have python enabled binaries.

4. Testing
You can test whether there's python support by creating test.nw with

python
for n in range(1,6):
        print n, n*2,n**2
end
task python

and running it with 

mpirun -n 1 nwchem test.nw

which gives

  NWChem Input Module
                                -------------------


                               NWChem Python program
                               ---------------------
for n in range(1,6):
        print n, n*2,n**2
1 2 1
2 4 4
3 6 9
4 8 16
5 10 25
1 2 1
2 4 4
3 6 9
4 8 16
5 10 25
 Task  times  cpu:        0.0s     wall:        0.0s

Done.


Note:
for ROCKS/CENTOS it was not necessary to edit src/config/makefile.h


The relevant parts in the the build configuration are

export NWCHEM_MODULES="all python"
export PYTHONHOME=/opt/rocks
export PYTHONVERSION=2.4

Other than that, just follow http://verahill.blogspot.com.au/2012/03/building-nwchem-60-on-rocks-543centos.html

For LINUX64 look at lines 1960-1964

Change line 1962 to

122. DVB-T in VLC on Debian Wheezy

For some reason me-tv has stopped working properly today  (20/4/2012)-- I can't change the channels, screen size or drop down the menus. In order to quit, you have to kill the application. Something's clearly amiss. (Edit 22/5/2012: seems to be this bug https://bugs.launchpad.net/ubuntu/+source/me-tv/+bug/958751 -- 09/01/2013: it's been fixed now ) kaffeine, although a KDE app, also works well, and is very simple to set up -- the EPG  also works better than vlc.

This is Kaffeine, not VLC

This is me-tv, not VLC

Oh well.

Given that it's Friday night I had to come up with a quick fix.

I've got a Leadtek 1000 DTS, which lspci makes show up as
01:06.0 Multimedia controller: Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01)

See item 7 in http://verahill.blogspot.com.au/2012/01/debian-testing-64-wheezy-small-fixes.html if your card isn't recognised (Hint: enable PnP in the bios)

So, where's what I did:
1. Install gnome-dvb-*
sudo apt-get install gnome-dvb-daemon gnome-dvb-client vlc

2. Set up your tv card:
gnome-dvb-setup

This bit's easy. Just click your way through. Eventually you'll realize that while gnome-dvb sets up channels ok, it only support recording -- not tv watching. And the whole totem + gnome-dvb-daemon? Not working yet it seems.

3. Start vlc
vlc ~/.config/gnome-dvb-daemon/channels_DVB-T.conf

If all went well you are now watching TV!
You should have a list over channels in your playlist (ctrl+L).
The EPG support could perhaps be better (me-tv is awesome) but you'll find rudimentary listings by going to Tools/Program Guide.

As for me-tv...it might be the same as this bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=667731


 Looking at /var/cache/apt/archives I don't see anything obvious:
