Just for fun, I decided to set up an oracle database on one of my computers. Ended up taking most of the day though, because the Oracle installer is so broken on Linux...

Case in point: I went around looking for the sqlplus binary, and all there is in the bin directory was a sqlplus directory. The installer insists that sqlplus is already installed and refuses to let me reinstall it. So I redid the install from the beginning, and when I watched it in another window, I saw it create the sqlplus executable, and then overwrite it with a sqlplus directory. What kind of junk is this?! I've done several Oracle installs on other platforms (albeit an older version) and the installers were not nearly as crappy.
