Display Java’s Swing menus correctly in Linux Mint’s GTK LaF

Since GTK 3 has been introduced Java Swing applications have a bug in displaying their menus when using the GTK Look and Feel (LaF).

At Linux Mint Cinnamon:

  • Wrong font color of activated checkbox and radiobutton menu items (the font has the same color as the background and appears unvisible)
  • No menu separators

ShowAllPorts – RS-232 Portlister

GPS-Logger, Messgeräte oder USB-zu-RS-232-Adapter werden i.d.R. über virtuelle serielle Schnittstellen (Port) angebunden. Das Herausfinden des Port-Namens, um die Datenübertragung zu einem Programm zu initiieren,  ist aber oft mühsam.

ShowAllPorts listet alle reellen und virtuellen seriellen Ports des Computers auf. Es arbeitet mit eingebauten Schnittstellen genauso wie mit USB-zu-RS-232-Adaptern zusammen. Es erkennt auf Wunsch den oder die zuletzt angesteckten Adapter und  zeigt an, ob ein Port belegt ist. ShowAllPorts läuft unter Windows®, GNU/Linux, Mac OS X® und Solaris.

EXE-files accidentally associated with an application

It is nearly impossible to associate a Windows EXE file to a normal application. The context command “Open with …” is not available for this file type.

But broken EXE-files or wrong commands in desktop shortcuts can ask for a application to start with. When your fingers are faster than your brain you cannot start EXE files anymore because Windows try to open them with the application selected before.

Unfortunately you cannot start any repair tools or even the registry editor to fix the problem manually now.

This how-to describes in a few steps how to bring your computer back working correctly.
