Why not to print in a pdf file the pages you are interested in (from the pdf version of the magazine) and then concatenate the various files into a single pdf ?

Re: MagPi 74 Missing code

Hi Brian,

Thank you very much. I've just ordered a copy of your book that I would like to use to teach my 15 year old dougther the fundamentals of game programming. The code is very useful to give her the feeling of what such a task is.

Again thanks for your very valuable work.

Re: My RPi model B+ won't turn on, is there any way to revive it?

Just to add some noise...
Do you know any other people living near to you and possessing a Raspberry like yours ?
If so why not to try a functioning set of power supply and Sd card ?

Re: omxplayer on startup: no module named omxplayer

Not sure since you did not show your script... but I suspect that you have to specify the full path of omxplayer.
