All,
As usual it never rains but it poors. I have a number of questions, and was wondering if anyone else on the list could help.
1) Is it possible to configure linux to turn an ATX pc off when you run halt?
2) Who was the person on mondays IRC who had started a open tshirts project?
3) Does anyone know if and what is happening on 29/04/01 with regard National linux day? We only have 29 days left to plan!
4) And finally, I currently refuse to buy a DVD player(as in Hi-fi seprate) for a number of reasons, most notably I feel that region coding is an infringment on my rights. But I do feel alot happier with the idea of playing DVD's from linux with the DeCSS(or similiar) code. Can anyone advise on what I would need to play DVD's full screen(or even better 16:9 on a normal screen) with normal stereo sound out the sound card.
4-b) What would I then require to output the sound to a AC-3 decoder?
Thanks
D

Yes.
As other people have said the way this actually happens is that Linux requests that the APM BIOS (Advanced Power Management) shut down the power supply.
In order to to that the Linux Kernel needs to be configured to use APM - some are and some aren't. As an example the kernel images from Debian don't use APM by default. If you build the kernel yourself it's one of the options you can pick - if you turn on APM support you can leave all the other APM related options at their default values and the power off will start working.
Of course the "power off" isn't completely off and you may find the BIOS has the capability to start the machine back up at a specific time, so you can use that to get the PC to start up at the beginning of surtime, say, do some work with the net and shutdown again afterwards.

I don't know, sorry.

The impression I have is that there will be some demo Linux systems running, demonstrations of the Linux install process and some people installing Linux for Punter after they (the punters) have signed a suitable disclaimer. I guess there will also be questions from the punter which we will do our best to answer.
If anyone else knows more perhaps they could let us all know.

I have never really looked into this, but a quick web search turned up a few references which may be woth checking out:
http://gape.ist.utl.pt/ment00/linuxdvd.html http://home.germany.net/100-5083/ http://lurch.ucd.ie/~conormc/linux/dvd.html http://xine.sourceforge.net/ http://www.linuxvideo.org/
4-b) What would I then require to output the sound to a AC-3 decoder?
AFAIK DVDs are recorded using MPEG (which version I can't remember) in which case I would expect that was is recorded on the disk is an encrypted MPEG system stream. In the that case the playback sequence is that the data stream is decrypted returning it to an MPEG system stream, the system stream is de-multiplexed into separate audio and video components each of which is fed to an approriate decoder. Whethe ryou would have to get the various bits separately or whether there is a player that does everything end to end I don't know. It should certainly be possible to construct a player from bits as MPEG video and Audio decoders are freely available.

Other people have already answered this, but basically read the howtos for ACPI and APM stuff.

All,
Many of you should know of ESR or Eric S Raymond. He is a well know Hacker and writter on the subject of hackers and hacking. He is most famous for writting the book "The Cathedral and the bazaar". If any of you have looked at his web page (and you should) http://www.tuxedo.org/ you will notice he has written a number of essays and articles on hacking and hackers.
But his latest essay has to one of his most bazaar yet http://tuxedo.org/~esr/writings/sextips/
as the URL suggests is his article on how geeks can score! Well I thought it was an interesting read:o)
Also of note on this site is the jargon file which is a dictionary for hackers http://www.tuxedo.org/jargon which is also published as the book "the New hackers dictionary" which is worth a read, aspecially the appendices.
Thanks
D

To turn off ATX power supplies on shut down is an option when you build the kernel. You may have to use real mode shut down, othewrwise the PC may hang.
As for regionless DVD players, I have a Panasonic DVD-A160 multi region player bought from Richer Sounds which is great :-)
Hope That Helps
