WordPress Twenty Twentythree: dark theme input fields
While the recent WordPress themes support dark modes quite well through their colour schemes, one still has to fiddle a little bit with manual CSS adjustments for the input fields.

How add a Python virtual environment to your Jupyter Kernel list

How to manage multiple Git repositories with a simple bash function
In the past I have already worked with a project that consisted of multiple Git repositories in a common project folder. For tracking each repository’s individual state together, Google’s repo tool was used.

How to include more symbols into your WordPress blog’s social link menu
For my blog, I use the WordPress theme Twenty Sixteen that supports adding links to my profile on typical social media sites like Facebook, Twitter, Instagram et al.

Bash: How to find all files modified on a certain day
The following bash function (e.g. stored in your ~/.bash_aliases) finds all files within a directory that was changed on a specific date.

This is an update to my 2015 post on horizontally aligning text in beamer columns with surrounding text. In this article, I am going to add the request to also justify alignment of all text. At the same time, I am simplifying the solution from last time:

How to create a nicely formatted Excel table from a pandas DataFrame using openpyxl
When I want to save the current state of a pandas DataFrame for “manual consumption”, I often write df.to_excel(‘foo.xlsx’) within my IPython session or Jupyter Notebook. However, the default style does not look pretty and often needs manual adjustments (e.g. column widths) to be usable. If you want to create custom reports from pandas, you…

How to use TeX comments to save yourself from always re-configuring TeXstudio
This posts documents an easy to miss feature supported by several LaTeX IDEs, TeXstudio in my case. They allow to cut short some otherwise tedious steps when switching between documents, by embedding a part of this variability into comments within the source files. This increases the portability of a document between TeX installations, increasing the…

How to use TikZ externalize with PGFgantt
I recently switched on tikzexternalize on a document with several figures created by TikZ in it. Activating this Tikz library has the advantage of compiling the figures only once (if unchanged), speeding up the creation of the completed document. As a nice side benefit, one gets the images as separate PDF files, which in my…

How to only color external links in LaTeX
Package hyperref is quite handy for making a compiled LaTeX document more accessible, by allowing to quickly jump to references (back to the text with package backref), section headings (from the table of contents) and weblinks. By default, links are marked by a coloured rectangles, which only appear on screen, not in print. If one…
