Re: Combine tv-out from raspberry with normal tv

are you talking about sending out your pi's video (and i would imagine audio as well) on an RF signal into the cable system? if so, you used to be able to back-feed a TV channel through cable systems. the CATV distribution amps had a directional coupler, where everything above 42Mhz went in the "for...

Re: Why does RPi need to pass FCC and CE?

generally any device that might emit radiation anywhere from 9khz to 300Ghz needs to be certified by the FCC. audio equipment (i.e. analog amplifiers in the audio range)normally doesn't have to be certified, because speaker wires have the conductors close enough together, that they don't emit. a cla...

resize root partition, but not to fill whole card

i'd like to resize the root partition on the raspi. it's a 4G image on an 8G card. the thing is, i want to keep a rather large pool of unused cells for wear leveling, so i only want to expand the partition by 1 or 2G. is there any safe way to do this?

Re: files and directorios permissions

it's a bad idea to set a file permission to 000. only root or the person that has write access to the folder can delete it, and i think the only thing that CAN be done with the file is to delete it. the only time anybody would ever want to use permission 000 is if only the presence of the file is re...

i'm not sure if you could dd the partitions to an NFS share, that might be one way to make a backup while the pi is running of it's possible.... you can copy all of the contents while the pi is running, but dd'ing it while it's running might not be such a good idea.... you are still writing log file...

Re: sd card life running a pi 24/7

no turbo settings, running "plain vanilla".

i did notice that the main partition is ext4. this uses journaling. this means a fair amount of writes during normal operation. wouldn't ext2 that doesn't have journaling have been a better choice for a flash drive?
