Boeing 787s To Create Half a Terabyte of Data Per Flight 213
Qedward writes "Virgin Atlantic is preparing for a significant increase in data as it embraces the Internet of Things, with a new fleet of highly connected planes each expected to create over half a terabyte of data per flight. IT director David Bulman said: 'The latest planes we are getting, the Boeing 787s, are incredibly connected. Literally every piece of that plane has an internet connection, from the engines, to the flaps, to the landing gear. If there is a problem with one of the engines we will know before it lands to make sure that we have the parts there. It is getting to the point where each different part of the plane is telling us what it is doing as the flight is going on. We can get upwards of half a terabyte of data from a single flight from all of the different devices which are internet connected.'"

Hopefully, they meant a TCP/IP connection, not "Internet" connected ;-)

Admittedly sudo echo "1" creates the most powerful "1" there is, but it's still not quite enough to affect permissions checks on the redirection.

You don't want to run echo as superuser; a regular user can echo 1 to the program's own stdout just as easily as superuser. The shell is what opens the output file (/dev/landing-gear-doors), so you either need to run the shell as superuser or have a different program as superuser which opens the file. Either of these will work:
[dave@hal-787 ~]$ sudo sh -c 'echo "1" >
[dave@hal-787 ~]$ echo "1" | sudo tee

As far as I know, "sudo -i" is the best option. This way also the home directory is changed to /root, so that the configuration files (or history files) in the home directory of your regular user aren't suddenly owned by root.

If you find yourself doing commands needing sudo, try this.
sudo !!
!! will repeat the last command.
