AltME groups: search

The launch environments are different in that the shebang path is 
used by the shell to know what to do with the script. You can also 
run a REBOL script in the linux terminal with: rebol -qs script.r 
and it will be the same script as under Windows. It might look a 
little ugly, but you could wrap your windows REBOL scripts in a shebang 
script.

Yes, I'm searching for a simple way to start my rebol script under 
linux wihtout having to write long command lines becauseI use the 
include wrapper from Lad too. So the line would become really long.

Maybe a starter script is the way to go.

And, is there a list of required libX... ?

Regarding the shebang line, if you edit a script with one on Windows, 
you'll have to make sure that the shebang line still ends with just 
an LF

I have one strange effect, that a Rebol script using a DLL works 
on Windows whereas on Linux I get a SEGVAULT.


How can I best track this down? I tried GDB but didn't made it to 
load rebol, include script, script etc. until I could start the whole 
thing.

Is there a "simple" way to get more information than just: SEGVAULT? 
Is it always a memory-problem?

Command/View needs X just like View does, even if you are just doing 
console stuff. Have you tried a Command build, or Core?

Gab, thanks for clearifying. BTW: Is this somewhere documented? I 
think its a quite importan piece of information.

I think there is a list of needed lib files that some distros may 
not include in the basic install. I assume they can be added....

That was the first thing that came to mind, but I'm playing around 
with a similar scenario and it doesn't work for me either.

like this 
dtach -A /tmp/mydtachsocket -z bash

yes, then you can hit Control - \ to disconnect, and dtach -a /tmp/mydtachsocket 
to reconnect

wow .. it has a text gui :)s

found a rpm, and it's working.  Thanks!

I have a problem with a CRON job. Running it by hand works, but it 
looks like it's not working if run via CRON.

How can I write some message to the system logfile from inside a 
shell script? Is there a command for this?

I won't be physically near that box now for a couple of days.  I'll 
test it again when I'm able.

Ok, when Cheyenne is started, it searches for a %httpd.cfg file in 
the same directory. If it doesn't find it, it writes down a default 
one. So if your cheyenne binary doesn't have the rights to write 
in its directory, that would the cause of the error.

oh no, it's quite a different file name ....

You can use Gab's workaround for that : write a small shell script 
that run cheyenne and run the script with sudo.

not seeing this request to write a cofiguration file at present

I was installing ubuntu Jeos, and it seems to find the NICs, and 
gets the UTC time etc.  But when it starts up, ifconfig -a only shows 
the local loop adaptor.
And if I try and startup eth0, it says it doesn't exist.
Ideas?

Since Gutsy, the first couple of lines of /etc/iftab


# This file is no longer used and has been automatically replaced.

# See /etc/udev/rules.d/70-persistent-net.rules for more information.


The system for naming / managing eth0 eth1 has changed.  I had to 
mess a file in the path above to get my eth0 back.

One is a Via Rhine and the other a Realtek chipset

Here's another JeOS annoyance .. I installed on a  Compaq PC with 
USB keyboard. It asked me about keyboard type etc ... and I think 
I manually selected USA.

But when it boots up, it doesn't recognize the keyboard anymore :(

So, I am going to have to reinstall, give it a fixed ip address so 
that I can ssh into it

As far as I know, there is no USB module in JeOS. JeOS is designed 
to be run inside a Virtual Machine, not as a Virtual Machine Host.

Connecting and using certain sites has often been really difficult, 
like ubuntu updates, ubuntuforums, my bank's online banking, and 
rebol.org, to name a few. Rebol.org I've noticed has been really 
slow.

Wait a minute, before the upgrade, I did a *hardware* upgrade, replacing 
the motherboard and 32-bit cpu for a 64-bit one. This is when 'eth0' 
changed to 'eth1' and I had to muck about to fix it.  <--- This is 
probably related to the network problems.
(So much happened since then, I keep forgetting about this.)
My solution is probably to do a fresh 64-bit install.

Also, are you using wireless networking? I have a machine running 
Hardy and ended up needing ndiswrapper to get wireless working well. 
The following instructions worked for me: http://ubuntuforums.org/showthread.php?t=766560

I haven't done it myself, but someone posted about it a while back...let 
me find the thread...

Thanks for the link. I remember seeing the original announcement. 
So it looks like a pretty easy hack.

ldd    will list dependencies for any object or binary.
Tracking which package (as Robert mentions can be a pain, but)

after  apt-get install apt-file   and  apt-file update   it gets 
easier.

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"

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).  :>)

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)

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.

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.

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

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 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....

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 :-)

Using a cheap Gigabyte H4670 videocard ... and an Athlon dual core 
3000 ... so a slow CPU.

So what is everyone's fav flavour of Linux now a days?

It's been years, since I used Linux on a daily bases. But Ubuntu 
seems to be popular among the young people at university.

Still, Debian. I like that you can start very small, has a very powerful 
package manager and works really great.

Gobo, Unbuntu, Debian

So far three...


I'm going to put together a list of applcation I run regularly, and 
then we can weigh this again...

Debian;  The best development model, (ala REBOL).  Deliver when ready 
and ignore the peanut gallery shouting "it's late!"  ;)  


Off-topic; Sadly, my second favourite wiki-forum-chat-combo-thingy, 
TikiWiki, is moving toward the ever useless every 6 months release 
cycle.  Not a valid model for a volunteer workforce, imho.

A related question. Which desktop?

I'm using Gnome.

I REALLY don't like Gnome.  I prefer to use Enlightenment but it 
has an extremely slow developement cycle and takes a while to get 
it configured to where it is really useful.  It has it's downsides 
but I've never found a desktop/window manager that even comes close 
to what Enlightenment does.

Tikiwiki is actually a very cool concept, most people don't realize 
how cool it is....(it is a wiki that works offline).

does anybody know a video player for linux that supports those apis? 
(not just nvidia, ati too)

Had a power outage in town, and my red hat server had to be shut 
down uncleanly since although it was protected by a UPS, the screen 
wasn't.  On rebooting, the raid array had become critical with one 
of the drives dead.  Unfortunately the good drive had developed a 
corrupted file system as well :(

There's a FAQ on the site about Ext3 access.

i had a read/write driver installed on windows and used it regularly 
without problems.

anyone using ZFS then? I'm tired of being bound to an OS with a file 
system.

ZFS: I looked a bit into it. I think it's a very nice FS. OSX has 
only read support, so not of much value.

That's why I asked. It's an informal poll, but not a secret one :)

RedHat. (but Ubuntu will do as well). I would just say go for the 
one that has the largest community.

RedHat as a business is doing well.

Although it will download quite a bit more during the installation 
process.

Debian, as many small Live Cds use it as a base

There is a porting difference between Ubuntu and Debian, though; 
and between Ubuntu versions

that's a ubuntu variant?

I run R3-alpha A33 Linux/Fedora 2.6.18 (http://www.rebol.com/r3/downloads/r30-core-a33-p421.gz) 
in a Kubuntu 8.10 CD-Live ( I think it's based on Debian ) and it 
seems to work ( I can chat )

And then, I download Rebol View 2.7.6 for Fedora (http://www.rebol.com/downloads/v276/rebview-fedx86.tar.gz) 
and it run perfect in a Kubuntu 8.10 CD-Live, better than Rebol View 
2.7.6 for Libc6, Debian (http://www.rebol.com/downloads/v276/rebview-linx86.tar.gz),for 
the last you need to install libstdc++5 and gcc-3.3-base.

I'm a big fan of puppy too! That's my main prob with most linux...bloat. 
Is not bloat the reason we are trying to get away from windows?

Since Debian 5 is out. Is there a simple upgrade path from 4 to 5? 
I know about "apt-get upgrade" but does this  work without any hassels?

Well, I run a xen DomU but not on a LVM setup. So a backup is not 
that simple as doing a snapshot.

or is there a daytime server for ubuntu...I searched google but no 
luck.

I am having some issues running 276 rebview on the fractured Xandros 
that comes on an Asus Eee Netbook ... anyone else trying Rebol on 
an Eee (mine is just a linux Atom 900A)

I have put eeeBuntu on a LiveUSB (the base version was only about 
600 Mb ISO ) and may install that as my debian

To use a port under 1024 in linux you have to be root

I did notice something strange, though - enough failed attempts at 
opening a listening port, and rebol can't open any more.  Have to 
start a clean session

Gabriele, that's odd ... the linux versions are cheaper!  And i have 
quite a few spare XP licenses ...

It depends on which country you live in. Installing XP on it is not 
a simple task though - you need to PXE boot your installer.

I recommend awxLink if you want to use it with XP - it's a lot easier 
than trying to get software to install on D itself.

That wasn't enough, that box needs to run a View program (and basically 
just that, though since now it's there it also runs Skype etc.). 
It was a replacement for a old (10 years old, and it was low spec 
back then) PC that literally exploded.

probably, it was the power supply. i didn't open it is there really 
was no point. the pc still works after replacing the power supply 
with one I had around, though i don't think it would last more than 
a couple months, and it's too old to be used for anything.

Those power supplies can make a rather loud bang with smoke etc :)

We can't be the only ones wondering how to do this, so I will check 
google for a tool to monitor installs....

Anton, thanks, I'll take a look

What distribution is that? Both rpm and dpkg allow you to build a 
binary package from a source package automatically.

if you have different distros/versions it can be a bit more complicated, 
depending on dependencies and so on.

I use debian. How can I create such a binary package from a source 
package? Any reference to this?

Is there a Debian-format source package? Then creating the binary 
version shouldn´t be hard, although I don´ t know the command

If you don´t have a Debian package, then it would be quite a lot 
of work to create one

never did such a thing myself, though

Well, in Rebol/View 2.7.6.4.2, I can paste the multiply sign (copied 
from ascii-math.r) straight into the console and it shows correctly. 
In a field, however, it shows incorrectly, eg. if I try to paste 
it in the field:
	view layout [f: field]
I get two characters,  'Ã' and a dotted box, displayed instead.

The binary information is correct, it's just not rendered correctly, 
for if back in the console I do:
	probe f/text
then I get the multiply symbol displayed correctly again.

So it looks like View face/text rendering is expecting 8-bit ascii 
of some encoding.
Probably ISO/IEC_8859-1

Yes, it will be an 8-bit single character encoding system. I believe 
on Windows, it is the system default CodePage and on Mac it is MacRoman. 


Your message shows the 'square-root' sign in AltME on a Mac and 'Capital 
A with a tilde on top: in Windows.


Perhaps you could describe the first of the two characters displayed.

On more close inspection, what I see here in a Rebol/View 2.7.6.4.2 
view face/text looks very much like ISO/IEC_8859-1.

The A with tilde on top is what I see here in Altme in wine on linux. 
(Makes sense.)

I don´t think X needs to be running. In any case, this also happens 
on some Linuxes with X running. It´s one of a few errors that currently 
prevent R2 from running on a number of Linuxes

Does anybody know what must be the size of /usr/sbin/suexec with 
Apache 2.0.52 or where I could find this info ?

Actually, I have :

[[root-:-wpc3104] /]# find -name suexec -ls

7819049   20 -r-x--x---   1 root     root        18684 Mar 26 04:43

A Web server of my client was hacked yesterday and I'm trying to 
find what could have been changed.

I'm an old unix user (student time) so linux is a cousin. I'm not 
totally lost, but don't know exactly where I'm.
So how can I make the package manager checking ?

I have a new Webserver to install.

I have the choice of the OS to install. Don't know wich one to choose. 
Any opinion of wich is best ?
- Debian 4.0 + Plesk 8.2
- Fedora core 7.0 + Plesk 8.2
- Ubuntu 8.04 LTS + Plesk 8.6
