Last week, I spent some time implementing various color manipulation
routines. The ultimate goal was to find a way to determine if a text in
a certain color was readable on a background with a different color.
Org-mode has a nice option which allows you to show
week-end days in a different color in your agenda. That means that Saturday
and Sunday (when I do not work) are fontified with org-agenda-date-weekend.
Last week, I worked on my
Google Maps for Emacs
extension. I've introduced a new format handling for locations which include
the longitude and latitude. The initial format was just a string describing
the location, which was obviously too limited.
