Compiling Muesli Fortran

Here is the code you need to compile and install the free numerical and graphical MUESLI library, developed by Édouard Canot [1].
sudo apt-get install 'libatlas-dev liblapack-dev zlib1g-dev libreadline6-dev imagemagick \ 
libx11-dev libpng12-dev g++ gfortran' #installing dependencies
 Note: for Ubuntu 10.04 replace "libatlas-dev" by "libatlas-headers")

tar xvfj muesli-linux-all-2.6.3_2012-05-03.tar.bz2 #untar

cd muesli-linux-all-2.6.3_2012-05-03/GNU_GFC
./configure --f90=gfortran --blas=/usr/lib/ --lapack=/usr/lib/lapack/ #configuring

make -s distclean #clean your distribution from previous installation
make -s (or for detailed output: make MODE=verbose) #compiling; this will take some time

cd tests #testing
make #make the test files
./run_all #run all the made test files

cd ..
make install #installing

cd tests/fgl #testing fgl
make #make the test files
./run_all #run all the made test files

Ubuntu 12.04 & Cinnamon

Hello again,

Precise Pangolin

Those who will try Ubuntu 12.04 & have a multitouch touchpad will notice the new feature (when enabled)!

Some not very apparent new features (relative to 10.04 & not 11.04 or 11.10!) are:
  • Installation time (i.e; start of copying files to notification or required reboot): 6~7 minutes.
  • Properties of an image in the image viewer gives you the folder name the image is located in & the ability (which I like) to open this folder by clicking the name.
  • Two-finger scrolling: In the "Mouse and Touchpad" settings, under Touchpad I enabled horizontal scrolling (which I do not understand why it is not enabled by default) & chose "Two-finger scrolling" instead of "Edge scrolling". The latter was not comfortable in my case; I sometimes couldn't lock the scroll & use it, but with the two-finger option (which needs some time to get used to) is much better; I can now use two fingers anywhere on the pad to scroll not just verticall or horizontally but in any direction (i.e; both vertical & horizontal).

Cinnamon

I'd also like share with you the relatively new desktop graphical user interface (GUI): Cinnamon. Below are two images of the desktop, which unlike Gnome 2 which has two panels, has only one main panel.

Cinnamon might very well appeal to Gnome 2 users who do not wish to switch to neither Gnome 3 that Fedora employs nor Ubuntu's new Unity.

A particular feature employed in Cinnamon that adds to Gnome 2 that I really appreciate is a graphical feature. What I really like is the Mac-like drop-down window when saving a file. All I can show you is the screenshots below:

Ubuntu 12.04LTS (Precise Pangolin)




Ubuntu 12.04LTS, otherwise known by Precise Pangolin, is coming soon; it is currently in Beta 2 testing. The final release should come in April. Here are a couple of images:

Welcome

Welcome to the blog!

This blog has been set up to include posts about, as the name implies, computation & physics. This includes posts mainly about:
  • Linux & Ubuntu,
  • the shell (aka terminal),
  • programming (this is going to be rare as there are lots of other better online resources),
  • physics, astronomy*, astrophysics,
  • scientific software, computational (astro)physics,
  • what ever I see interesting for such a blog,
  • & the like.

If you're interested in the above combination of topics then I suggest you follow the blog by email** (bottom of page).

Also note that this blog is a students blog; I am still a student learning the above mentioned topics!

Welcome aboard!

*I might also refer you my website &/or blog!
**The frequency of posts will be low, so I won't be filling up you're inbox.
