futurenet.com.script would complete, but as we were watching TV
any pop-up would be invisible behind the playback.
I brainstormed several schemes but nothing simple
did the trick.
Then one day I was tapping away in a terminal on
my laptop while copying the latest LXFDVD to a flash
drive. When the copy finished, as I was already in a
terminal, rather than fight trying to find the little
button on the DVD drive I just typed eject and the
drive pinged open. A lightbulb went on over my head
(is the eject command supposed to do that? – Ed).
So a quick edit to the script and that was it – each
time the recordings were all copied and it was ready
for the next flash drive, the script would just eject
the DVD drive on the PC. Brilliant... what could
possibly go wrong?
A few nights later we were sitting in the dark
watching a scary film. The copy finished just as the
tense bit of the film built, the DVD drive shot open
with a loud click and the pair of us jumped a couple
of feet! This finally gave me the nudge I needed to
drill a hole through the wall and run an Ethernet
cable to the theatre PC.

We’re glad you’ve gone with the more sensible solution
of drilling holes in walls.
You’re firewalled
There are lots of Raspberry Pi magazines and
information on projects out there. I could do without
your Pi User articles. I would prefer more info and
examples on your tutorials, especially on setting up
firewalls, security apps and encryption. I like your

Getting RC with the Pi
My ongoing project is to take old RC cars
and replace the receiver/controller IC
with a Raspberry Pi. I have tried a
number of different solutions such as
WebIOPi and Wyliodrin, but Les
Pounder’s article on Flask in LXF229 gave me another solution
that I have got working and which I really like.
Another aspect is to untether the car from the access point,
and I wonder if Les could do an article on setting up a peer-to-
peer ad-hoc network between an android tablet and a Raspberry
Pi? [Peter found a solution at http://bit.ly/LXF249point].
For the benefit of other people who don’t like doing things the
easy way, I have discovered that each of the three scrap RC cars
have a different receiver/control IC, but all the ICs have the same
pin-outs. I’m tempted to use an IC socket as the connector
between the Pi and the car. Also, it has been necessary to power
the Pi separately from the motors.
You can see an early attempt at http://bit.ly/LXF249picar.

I get your point, but as a Linux and open source
magazine we’re going to cover all the topics that
encompasses, and as the Raspberry Pi is very popular
we’d be silly to ignore that. Giving it just eight per cent
of the magazine each issue doesn’t seem outrageous.
But we are going to write about firewalls, as it turns out
Jonni is getting paranoid about IPv6. Again.
