How to list subdirectories recursively with total size
Just a note to myself, as I always have a hard time understanding the find manpages. To list the directories and subdirectories up to a certain depth, “simply” enter: Option maxdepth states how deep the subdirectories should be listed, option type restricts output to directories (d).

If you use the Microsoft Sculpt Comfort Desktop with its gorgeously sculpted keyboard and the round pebblestone mouse, you might not need the brightly branded “Windows” button on the mouse.

How to horizontally align beamer columns with surrounding text
If you (like me) assumed that placing two columns width 50% textwidth next to each other would align with preceding or following text on a beamer slide, then you are mistaken (like me). Fortunately, a discussion on Bug #262: Provide more usable columns environment showed a viable solution in form of the optional argument onlytextwidth.…

How to use TikZ for inline polygons
The trick is to define inner sep=0pt when beginning the tikzpicture environment, as I learned from pgf bug report #172 minimum size in regular polygon fails for small length from last year.

Unfortunately, Python does not automatically reload packages and functions after an initial import foo, simply for performance reasons.

How to use custom colours in LaTeX
I will post short minimum working examples (MWEs) of minimal LaTeX documents, showing a certain feature in action. Though the well-maintained LaTeX Wikibook is a much more extensive resource than a collection of such examples could ever be, they show directly compilable examples compared to isolated snippets. I start simple: custom text colours, using different…

How to list size of directories in current folder
Note to self, it’s deceptively simple, once one manages to read the manpages properly: [code lang=”bash” gutter=”false”]du -hd 1 /path/to/directory[/code] If directory is the current folder, this shortens to: [code lang=”bash” gutter=”false”]du -hd 1[/code]
