| I searched high and low for solutions to the "extract animated GIF frames in Python" | |

| on several partial examples around the web (mostly Stack Overflow). | |
| There are two pitfalls that aren't often mentioned when dealing with animated GIFs - |

Let's say somebody temporarily got root access to your system, whether because you "temporarily" gave them sudo rights, they guessed your password, or any other way. Even if you can disable their original method of accessing root, there's an infinite number of dirty tricks they can use to easily get it back in the future.
While the obvious tricks are easy to spot, like adding an entry to /root/.ssh/authorized_keys, or creating a new user, potentially via running malware, or via a cron job. I recently came across a rather subtle one that doesn't require changing any code, but instead exploits a standard feature of Linux user permissions system called setuid to subtly allow them to execute a root shell from any user account from the system (including www-data, which you might not even know if compromised).
If the "setuid bit" (or flag, or permission mode) is set for executable, the operating system will run not as the cur

| if [ "$#" -eq 1 ]; then stdinmsg=$(cat); fi | |
| exec <"$0" || exit; read v; read v; read v; exec /usr/bin/osascript - "$@" "$stdinmsg"; exit | |
| -- another way of waiting until an app is running | |

| repeat until my appIsRunning(appname) | |
| tell application "Messages" to close window 1 | |
