Annoying malfunctions that are currently unsolvable by IT although they are objectively bad problems

Software

Matlab created or tries to create a Folder .MathWorks in your home directory

Permanent Link:

Mathworks invented some Matlab-related "agent" which is supposed to run in your context when you use Matlab. However, this agent wants to copy its runtime environment to your home directory (600MB per computer it's running on!). To prevent that, IT modified the institute-specific startup wrapper to detect traces of the agent, demanding you to remove the folder before continuing.

You might notice this error message upon Matlab startup:

mkdir: cannot create directory ‘/data/hu_username/.MathWorks’: Not a directory

Please ignore it.
