kcollins:  I have Rebol 2.7.6 running with zero problems on 64-bit 
Ubuntu Hardy fresh install, with no hackery...

old post..  x_x   I need to visit more often

And you can search with: apt-cache search <lib name fragment> to 
see what the packagename might be. Or use atptitude and press / to 
search and than N for next hit. Than + to install.

Anybody see what is wrong with this script? It is supposed to call 
ImageMagick to reduce the size of specific jpeg files in a directory. 
 It processes a few files, then locks up my computer.

rebol []
files: sort read %.
num: length? files
print ["Number of files in directory: " num newline]
count: 0
foreach file files [
	if all [find file ".JPG" not find file "Nain-"][
		newfile:  join "Nain-" file
		call/console reduce ["convert" file "-resize 25%" newfile]
		count: count + 1
		prin [count " "]
	]
]
print "DONE"

Never mind. It work now.

What was the problem ?

I was going to suggest putting a short wait after the call.

I think it will call imagemagick a lot of times without wait, like 
Anton suggests.

Either the /console refinement fixed it (I should have tested one 
more time before posting), or else using trace fixed it by slowing 
it down (kind of a wait substitute).  :>)

I've got mail for root ending up in /var/mail/root ... is there any 
way I can get this mail redirected to my gmail account?

I looked at the etc/aliases but you can't seem to alias to outside

the most simple way is to create a file /root/.forward with your 
email address in it

otherwise, you can use the virtusertable file to control what happens 
on incoming mail. you can send to a local user, forward to another 
address, run a command, and so on. (eg. you could call rebol, filter 
with your spam filter, then SEND to gmail, or whatever)

Thanks .. I'll look at that.

Can I keep a Rebol script running by starting it with: 
	script-name.r &

if the script has a shebang line? It seems this makes some problems.

Looks like using: nohup script-name.r & works.

Robert;  You may want to look at   screen   as well.  Pretty powerful.

What's "screen"? I''m using Linux without any GUI.

man screen

;-)

although terse I wasn't intending to be flippant

I used screen enough years ago i would have to re read the man page 
to use it now

No, no problem. It's just THAT obvious to try but screen is that 
general...

screen may not be installed by default.  And I think it may be best 
described as a multiple process enabled session multiplexor disguised 
as a teminal program

Another option is dtach, which allows you to detach from and reattach 
to a terminal session even if you completely disconnect from the 
machine in the interim.

dtach looks alot like all I ever used screen for anyway

thanks

or just >/dev/null </dev/null 2>/dev/null :-)

Gab, yes of course ;-) that's the "through the desert on your knees" 
approach.

Guys, thanks a lot. As always there is more than one way to do it.

Interesting problem to face, if some people think Linux is illegal 
to copy.

Yeah, we're brainwashed by the intellectual property industry

I don't usually, as I like to remain gullible, but I'm calling bullpies 
on the original e-mail.

btiffin, Are you saying you do not believe the e-mail? I find it 
hard believe the pro-microsoft stuff but the ignorance of Linux I 
do not doubt. I taught HS in NYC for 6 years and most teachers were 
clueless of computers in general.

Yeah, I'm calling bull on the original, but it's just a spidey-sense 
more than faith in humanity.  I did like the one comment mentioning 
some people thinking "it's illegal to erase Windows from my harddrive".

I've met people who think that what the original message said is 
true, so I think it's plausible.

Who has got better Linux support - AMD or NVidia? I am looking for 
MB with embedded gfx chipset, being able to utilise FullHD, so it 
has contain H.264, VC-1 hw codecs, and Linux must be able to support 
it ...

I'm not aware of any video decoding acceleration on linux, though 
there may be ways to get it I guess. it surely is not mainstream.

I would say NVidia.

thanks!

I set up a system with AMD 780 chipset a month ago and put Ubuntu 
on it. Installed Ati drivers and it works :)
Movies, 3d games.... It works....
Also tried same system with nvidia 9600 and it also works...
Driver support is becoming better every day....

this is good to know. What we are looking for is HW acceleration 
of H.264 and VC-1 support.

That's confined to add on cards.  I doubt you'll find that on motherboards 
yet.

Vladimir, video works very well on Linux, but it is not HW accelerated 
AFAIK. The ATI driver seems to have some support of it (but I'm not 
really sure, just getting XVideo support working took many days...), 
but I'm not aware of any video player taking advantage of that.

Petr, if you are writing your own video player, maybe you can do 
something, but don't expect it to be easy (well, maybe you can just 
stick to one specific version of the driver). Why do you want to 
do this? Isn't software playback good enough? 720p H264 works fine 
on this machine which is an old Athlon XP 2600+. Do you really need 
1080p? If so, isn't a cheap laptop MB able to give you that in software 
already?

Gabriele - I did rather extensive read on the minimal config of the 
thing, and it is like that:


- we are looking for embedded solution, we are space limited for 
our device, so no place for external gfx card either

- forget 1080p, unless you are about to use monstroze performance 
CPU, which will be power hog in a kiosk system

- so - you have to use HW, which contains codecs directly - ATI 680G 
chipset is minimum, 780 or 790 is beeter. nVidia 8200 or 9400 (Ion 
platform), VIA S3 500 family, Intell Poulsbo chipset

- with above, you don't need so much powerfull CPU, dualCore Atom 
would be able to play your video

- this one page is a good reference - http://www.tomshardware.com/reviews/amd-780g-chipset,1785-3.html


We are still investigating the situation. We started our work for 
Windows, but would like to move to Linux in the long run instead. 
We want to use ffmpeg project, but we will have to see, if its playback 
somehow utilises HW acceleration, or not. We will also look into 
projects like mplayer and VLC. Another problem I read about is, that 
so called HW acceleration is not always utilised. E.g. H.264 is not 
so clearly defined as mpeg2, and hence there is already plenty of 
videos, which are in MKV container, H.264, but using some super-set 
of features, which will not be supported by HW acceleration anyway 
... so - lot's of work for us :-)
