I just stumbled on another reason to dislike Matlab: the stupid inconsistency of the short-circuit behavior of the elementwise logical operators: the statement

Bash scripts are handy for putting a bunch of longer running jobs in one batch. In some occasions it can be useful to know which command is running at the moment, especially when the commands do not generate output themselves or this output is redirected to files.

I'm experimenting with using a Subversion repository through Git. That way I can keep better track of my own (experimental) work, without polluting/destabilizing the central Subversion repository with small incremental commits. Git comes with a svn sub-tool that takes care of all the interfacing between the local git repository …
