If you will ever have to go through the hell of debugging Qt-applications, you might face the problem of printing the contents of QString objects. If you call print on a QString object in gdb, the output will most probably look like the following: {static null = {<No data fields>}, static shared_null = {ref =... » read more

Moreover, code documentation is essential in projects where teams with several people work on the same code base. Thus, the... » read more

Well, you’re right 😉 There you go:... » read more
Hey, I figured out that nautilus, the file browser of GNOME, has a nice feature of adding scripts to the context menu (right click). For instance, you can place the following two scripts in ~/.gnome2/nautilus-scripts/ and make them executable (chmod +x).

The initial version assumes that all pdf files have the same name pattern and end with a number: \documentclass[a4paper,landscape]{article} \usepackage{pdfpages} \usepackage{forloop} \begin{document} \newcounter{ct} \forloop{ct}{1}{\value{ct} < 8}%... » read more

One can set the caption font with \SetAlCapFnt, but then the complete caption (including caption label and caption text) will be changed. I can provide... » read more
