## why_no_777.txt
I received the following comment from a web developer after I told him I wouldn't make his volatile files directory chmod 777 so Apache could write to it.

"777 tends to scare sys admins, so I understand."

Here's my response:

"Yes, it scares us and it should scare you.

"Think of your account like an apartment. If you set your permissions to 777, anyone who can get into the building (onto the server) can make changes: raid your fridge, steal your cat, replace your pillows, or plant evidence pointing to a crime you didn't commit. Even if they did none of those things, you can get skeeved out by the possiblility.

## dconf annoyances
I see a few things in /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.preferences.gschema.xml that aren't in Gnome-tweak-tool.

So I make a change and then do a find to see where the changes were made: .config/dconf/user -- which is parsed by dconf.

$ dconf dump / |grep -C1 raise
[org/gnome/desktop/wm/preferences]
auto-raise=true

That can be changed on the command line.
