My co-worker just got an iPod so I thought I would try and encode a DVD onto it (an unencrypted DVD that I own, for backup purposes only, not to be used for public performances, etc, only I looked at it, I shut it off when someone looked over my shoulder...blah blah). The ffmpeg that comes stock on RHEL4 is insufficient to do the transcoding. I built a newer version and mucked around a bit and got this going. I have a simple wrapper (there are numerous versions of such scripts floating around).

This happens to me when I'm importing photographs, I end up with files called .JPG or .jpeg and I prefer .jpg.

for file in *.JPG
do

Say you have some files named a100 to a200 that you want to rename to b200 to b100 (it really does happen).

y=200
for x in `seq 100 200`
do
   mv a$x b$((y--))
done

seq is a fairly useful tool, it can also take a reversed list.

for x in `seq 200 -1 100`
do
printf "$x "
done

There are probably a million better ways to do these, but these are tricks that I keep using (I'm well on my way to becoming an old crusty unix guy :-( )


I purchased a Proxima DPP6850 off ebay. Because the projector is a few years old, it doesn't have any component video capability. It has composite, s-video and two rgbvh (VGA) inputs.


The Internet Control Message Protocol (ICMP) has many messages that are identified by a "type" field. I use the types to specify what actions to take in my custom iptables config.

Digital AV Out

To watch Gamecube games in progressive scan, you need to have a gamecube with digital out. Since 2004, Nintendo took the digital port off the gamecube. You can get your gamecube replaced with a model with the port directly from Nintendo.


  • Black/Blank Screen First time I tried it, kernel boots then nothing.

Sleeping

First problem, sleeping, the SATA bridge doesn\'t sleep properly and therefore doesn\'t come back after resume. The infamous SATA ACPI patch at http://lkml.org/lkml/2005/9/23/97 seems to have solved this for me. I added the patch to the latest FC4 rpm and renamed (to be polite).
