Ghosts in the Machine
Recently I could not use Meld to view the differences between two files. I ran Meld from the terminal and saw the following error message:
OSError - Errno 13 Permission denied
I tested Meld on two other systems. No problems. I tried a different user account on the same computer. Same error message.
I reinstalled some packages. No change.
Meld is a Python app. A little digging around the web revealed a possible clue. I checked the permissions of /dev/shm. The permissions were 0755 rather than 1777. I have no idea how the permissions changed.
I restored the permissions. I then could again run Meld.
This is how a person wastes two hours of life chasing ghosts in the machine.
