Sometimes the packages in Ubuntu are outdated (e.g. the geometry package in Ubuntu 12.04, see this forum) and it is necessary to manually include the package.
The easiest way for me is to just download the package from ctan, e.g. for the geometry package
find duplicate labels
when you get the warning:
There were multiply-defined labels
you could use following reftex command within emacs
M-x reftex-find-duplicate-labels

To install musescore on ubuntu flavors, like lubuntu or xubuntu, it might be the easiest, to use wine to install it. The "normal" way by using the repository did not work for me on Lubuntu 12.04, that means it did not install the latest version 2.0
sudo apt-add-repository ppa:mscore-ubuntu/mscore-stable sudo apt-get update sudo apt-get upgrade

Inkscape vector graphics (.svg) appear a little bit blurry when used in libre office impress (Version: LibreOffice 3.5.7.2, Build ID: 350m1(Build:2)), especially when text is visible on the graphics.
I think the easiest workaround is to export the inkscape graphic as a .png bitmap
File -> Export Bitmap
I got good results with the default settings (90 dpi).
The generated png can then be included into Impress.
There's a cool add-on (ExpandAnimations) for Libre Office Impress out there that let's you export a Libre Office presentation, even with animated (appear, disapper) effects.
You can download it at
https://raw.github.com/monperrus/ExpandAnimations/master/dist/ExpandAnimations-0.4.oxt
Open it with Libre Office.
Once the add-on is installed you can export animated presentations to pdf via
In Inkscape (from version 0.48) you can include mathematical symbols using Latex. In the menu bar go to
Extensions->Render->LaTeX Formula
and write your formula. Note that the formula will appear below your drawing area. So it might be necessary to zoom out to see the formula.
If you don't see the menu entry it might be necessary to install latex, dvips, pstoedit. In Ubuntu you can open a terminal (Ctrl + T) and insert following line (followed by the enter key. You are asked for your root password.)
If your matlab version is too old to support the function
datetime
you could use following lines to print date and time
c = fix(clock);
time = date;
dateANDtime = sprintf('%s-%i:%i:%.0f', time, c(4),c(5),c(6));dateANDtime e.g. 15-Mar-2015-21:29:46
If you need to read in a hdf5 file (.h5) in matlab, use the function h5read.
The syntax is
data = h5read(filename,datasetname);
The "filename" is obvious, e.g. /the/path/to/the/file/name.h5. The "datasetname" can be found by using the tool hdfview or by using the linux terminal tool h5ls
