Emacs Org-mode: Improve HTML export’s source block readability
The default colors used in Org-mode’s HTML export, e. g. the bright yellow, make the source code blocks unreadable. The following commands replaces the colors for improved readability:
FILE=notes.html sed -i 's/#0000ff/#000080/g' "$FILE" sed -i 's/#00ff00/#008000/g' "$FILE" sed -i 's/#00ffff/#008080/g' "$FILE" sed -i 's/#ff0000/#880000/g' "$FILE" sed -i 's/#ff00ff/#800080/g' "$FILE" sed -i 's/#ffff00/#808000/g' "$FILE"
Gnome Shell: Add keyboard shortcuts for switching to workspaces > 4

and paste your shortcuts in dconf's format, e. g.:

SSH-Verbindungen: ZeitĂĽberschreitungen vermeiden
Wenn nach einer Weile der Inaktivität eine SSH-Verbindung abbricht, kann es helfen, in der Konfigurationsdatei /etc/ssh/ssh_config bzw. ~/.ssh/config das Senden von Lebendigmeldungen (ServerAliveInterval, standardmäßig aus) zu aktivieren. Zusätzlich kann die Zahl der geduldeten, aufeinanderfolgenden Verluste solcher Nachrichten angepasst werden (ServerAliveCountMax, standardmäßig 3):
ServerAliveInterval 180 ServerAliveCountMax 3
Nähere Informationen können der Manpage ssh_config(5) entnommen werden.

Emacs in terminal: set background color
When running GNU Emacs in terminal (emacs --no-window-system), the background color can be set by the following command in Emacs' configuration file ~/.emacs:
(set-face-background 'default "brightwhite")
The available colors can be listed by M-x list-colors-display. Set the TERM environment variable to e. g. xterm-256color before starting Emacs, if there are too few colors listed.
Firefox: disable pdf.js system-wide
Create a file mozilla.cfg in Firefox’ installation directory (Ubuntu: /usr/lib/firefox; Windows: C:\Program Files\Mozilla Firefox) with content
pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");
Create a file local-settings.js in the subdirectory defaults/pref with content
lockPref("pdfjs.disabled", true);
Restart Firefox. In about:config, the setting of pdfjs.disabled is now set to true and is locked/cannot be changed any more.

Verwendung von Vektorgraphiken in LibreOffice
Im aktuellen LibreOffice 4.4.2 scheint die Verwendung von Vektorgraphiken inzwischen einigermaĂźen stabil und brauchbar zu sein, inkl. Export nach PDF. SVG geht in LibreOffice zwar schon seit 3.4, meine bisherige Tests mit Versionen einschlieĂźlich 4.3.2 hatten aber bisher immer nicht akzeptable Programmfehler aufgezeigt.
