pypar

Following installation of openmpi, and numpy (both required), pypar:

download:
mkdir ~/downloads/pypar
cd ~/downloads/pypar
wget http://surfnet.dl.sourceforge.net/sourceforge/pypar/pypar-2.1.0_53.tgz
gunzip < pypar-2.1.0_53.tgz | tar xvf -

sudo python setup.py install

failed.

python setup.py install

failed, complaining about a lack of write ability.

sudo python setup.py install

again, then worked! import pypar works, too! Odd.

On reflection, I think I needed to:

python setup.py config
python setup.py build
sudo python setup.py install

Yes. From clean, that worked. Mostly. Actually, there was a complaint about '-fPIC' and '-m64' being files that couldn't be found. odd. Then, later, I found sudo apt-get install python-dev was required, to remove errors re: python.h not being found. This needed an update, upgrade and dist-upgrade to work and I'm now getting error on update. hmmmm. ---- later, on another machine I did: sudo apt-get install subversion; svn checkout http://pypar.googlecode.com/svn pypar-read-only; cd pypar-read-only/source/; sudo python setup.py install; exit log back in and python, import pypar shows it works.

OpenMPI

sudo apt-get install openmpi-common

Didn't install mpicc or mpirun or mpiexec

sudo apt-get install openmpi-bin

mpiexec now works, but pypar complained that mpicc was missing.

sudo apt-get install libopenmpi-dev

! I can't find file `ecrm1000'.

and many others. Try

sudo apt-get install tetex-extra

This took a while.

! LaTeX Error: File `lmodern.sty' not found.

install lmodern to fix:.

sudo apt-get install lmodern

Skype on ubuntu 64

$ wget http://download.skype.com/linux/skype_ubuntu-2.0.0.72-1_amd64.deb
$ sudo dpkg -i skype_ubuntu-2.0.0.72-1_amd64.deb
$ sudo apt-get lib32stdc++6
$ sudo apt-get install lib32stdc++6
$ sudo apt-get -f install

I think only lines, 1, 2, 5 are required. Line 5 (I think) fixes the missing packages, reported from line 2.

Ubuntu shortcut key modification.

$ gconf-editor

/apps/metacity/global_keybindings Edit 'run_command_1' etc, to the key-stroke. e.g. z to set left win button + z. Watch that there's no space there.

/apps/metacity/keybinding_commands Edit 'command_1' etc, to the command to run, e.g. gnome-terminal

..... didn't work. I found that pressing 'z' without the win button launched the terminal.

Try xbindkeys:

sudo apt-get install xbindkeys
sudo apt-get install xbindkeys-config
xbindkeys
xbindkeys-config

Tested. It worked.

.gz, .tar, .bz2, rar

$ gunzip filename.gz # to unzip


$ tar cvzf foo.tgz *.cc *.h # to create. works for directories, too.
$ tar xzf foo.tgz # to extract

$ gunzip < file.tar.gz | tar xvf -          # to extract.  $ bunzip2 filename.bz2          # extract  $ tar -xvf filename.tar      # extract   $ tar jxvf filename.tar.bz2

$ unzip filename.zip

$ bunzip xine.bz2

and rar / multipart rar:

unrar x 1strarfilename.rar


--------------------- groups of files

ls *.rar | xargs -i unrar x {}



Wow.  That CUNT Gavin is reading over my shoulder.  I blame the parents.

.tar.gz

(He's still whittering on, with everyone in the room ignoring him.  What a cunt, honestly)

.tar.gz:  to extract,

$ tar xvf filename.tar.gz
