Yep, path requires valid REBOL.  So, use dir/"042" if you need to 
do that.

Why couldn't paths do that for us ? ie. to-path "042" becomes a word...

All I want to do is smooth it out, so sparing others these surprising 
error messages.

that could be solvable: convert the part to a string (or file). block 
then has a string. if you do to-path block, you get dir/"042", but 
that should be ok (with new pathes). its not more "buggy" than making 
42 from 042 IMHO. would be nice to get this, and pathes ending with 
"/" :)

How safe is catch?
	

I have some rebol applications serving message communication (around 
1000 to 2000 messages per day mostly) running for more than half 
a year on Windows2000 Server without interruption since the last 
update of the OS for security reasons.

Recently I had to add some message splitting:
one-message -->  [message-part-1 message-part-2 message-part-3]

I used a construct similar to this

forever [
	until [new-messages-available]
	foreach message new-messages [
		catch [
			if not important [throw]

   do-some-heavy-message-processing-and data-completion-using-odbc
			if some-tests [throw]
			message-parts: split-messages message
			until [
				catch [
					message: first message-parts
					do-more-conversions
					if other-tests [throw]
					deliver message
					emtpy? message-parts: next message-parts
				]
			]
		]
	]
]

Now I saw two crashes in one day.
I was somehow able to reproduce the crash 
Invalid data type during recycle
 

by playing again the history of one to two weeks. But the crash happened 
always processing another message.

By saying "by playing again the history of one to two weeks", do 
you mean that this removes all the network activity ? Is ODBC removed 
too ?
Is the crash always on the same message ?

And just do some minimal ODBC activity to see if that still triggers 
it.

It doesn't seem to do much that is useful..

(DO first tries to LOAD the decompressed string.)

The decompressed string was identical to the original string. The 
compression/decompression has nothing to do with it. The problem 
is in loading a string of code copied straight from an editor or 
somewhere. If that code had been MOLDed first it would have been 
OK.
>> mold #"^M"

== {#"^^M"}        ;<--------- note the double escape, this string 
loads properly.

Peter: about your ticket -211 about GET... GET has nothing to do 
with that :)

3130 Bug: On Linux, CALL interferes with TCP port wakeup, 3159 Bug: 
Linux: system port interferes with TCP ports

using it for some hours to do remote calls thru tcp, works. did not 
work with older rebol. IMO fixed.

about: http://www.rebol.net/cgi-bin/rambo.r?id=3363&do you think 
FIND should stay as it is for compatibility? or it's better to change 
it?

i have a wish: integrating 'comment in some more dialects. parse, 
layout come to mind. could then be used for embedded documentation. 
what do you think?

[Cyphre | Gabriele]: Do you still need more information about the 
Win98 crash or is it solved?

If needed I can send an echoed trace log file to your email address.

Romano, Anton: the new error!s were introduced to rebol instead of 
"face in more than one pane" and simmilar console prints.
regarding this error
** Script Error: Invalid graphics face object
** Where: view
** Near: show scr-face
if new [do-events]


I have got it when one of face/size coordinates are lesser than 1.

#3687 : bitwise ops - it was submitted at the start of the /View 
1.3 project (2003/2004). 

Both MacOS 9 and Amiga /View 12.1 (big-endian MC 680xx / PowerPC) 
have this bug for bitwise operations on series.

I had to do a workaround for %gzip.r (painful slow byte per byte 
operations) and %rebzip.r (calculations with integers.)

Yes, Hooray for Romano's FTP!  Just remember to disable your previous 
Romano FTP patch (if you have one) from your user.r.  I added a version 
check around mine:

 if (system/version * 1.1.1.0.0) < 1.2.110.0.0 [ ; View1.2.110 has 
 Romano's FTP handler built in.

  do load-thru site/patch/ftp-romano-patch/ftp-patch53.r  ; the old 
  patch
	]

I do not know, if this is comparable.

If I work with ODBC, pull out the network connector  and catch the 
error with try [], sooner or later I can observe a consecutive fault 
 either at a different part of the program doing something totally 
unconnected with  that  or a GC fault.
Either way the process is no longer able to work as expected.


In server processes I help myself in this case with automatic closing 
and starting a new instance of the program.

For norman new submition bug about error (unrecognised symbol ) when 
loading libraries .so files I have maybe the solution or explanation 
to this problem.... When you look to the error message on loading 
libraries submitted by norman in his post we can see that the problem 
is related to external needed library for example libSDL, libncurse, 
libogg  do not need other libs But  GTK and gthread need previous 
load of glib, libgdk, libpango, libgmodule, libpng, libint, libgtrhread 
and the list is long ;)...

write/append does not give back an error when writing to a disk without 
enough space

just do this

insert/dup mem-st: make string! 100'000 "1" 100'000
counter: 0
forever [
    write/append %/A/mem-tst mem-st
    probe counter: counter + 1
]

then you will see that it runs without writing

But OSes often signal the program of such an error after they detect 
it. Do the REBOL internals react to such a signal?

BrianH: Yes, I do not expect write to check for available disk space. 
But I expect an error, if an action is not successful. And this I 
do check and react according to the outcome.

From what I can determine the bug where select/skip on a string locks 
up the interpreter is related to bug #3327  My guess is that because 
/skip isn't skipping properly then it sometimes finds itself in a 
forever loop trying skip at the same point repeatedly.  Shall I submit 
this as a new bug references the expected relationship between these 
two or do we want to extend the description of #3327 to include this 
information as well?

Install but do not select .r association option, then uninstall - 
problems.

To fix this situation, rename currentuser/software/rebol/view key 
to viewold - this allows reinstall which you should do this time 
with .r association then uninstal works ok.

Did Dide submit his bug above ? It sounded like he wanted me to do 
it. :)

this looks strange:
>> o: make object! [test-word: none]

>> do bind probe reduce [to set-path! 'test-word to lit-word! 'test-contents] 
in o 'self
[test-word: 'test-contents]
== test-contents
>> probe o

make object! [
    test-word: none
]

simplified:

>> do probe reduce [to set-path! 'tst-word 1]
[tst-word: 1]
** Script Error: tst-word has no value
** Near: tst-word: 1

do probe reduce [to set-path! 'tst-word 1] should set tst-word without 
protests

I needed to handle this:


foreach [path value] [a 1 o/b 2] [do reduce [to set-path! path value]]

funny and "stupid" example:

do reduce [sp: to set-path! [] 1]

yarg... 'try was changed.. I just spent a half hour trying to figure 
out why a -short- peice of code would work!

USAGE:
    TRY block

DESCRIPTION:

     Tries to DO a block and returns its value or an error. ;What happend

     TRY is a native value.

It has nothing to do with TRY at all.

what does this mean?


   * Generate 64 bits of randomness from a good, well-seeded random 
   number generator;

ie. how large a seed do I need to get 64 bits ?

http://www.jwz.org/doc/mid.html
	

 In summary, one possible approach to generating a Message-ID would 
 be:

    * Append "<".


    * Get the current (wall-clock) time in the highest resolution to 
    which you have access 

    (most systems can give it to you in milliseconds, but seconds will 
    do);


    * Generate 64 bits of randomness from a good, well-seeded random 
    number generator;


    * Convert these two numbers to base 36 (0-9 and A-Z) and append the 
    first number, 

    a ".", the second number, and an "@". This makes the left hand side 
    of the message ID be only about 21 characters long.


    * Append the FQDN of the local host, or the host name in the user's 
    return address.

    * Append ">".

what do you want to do?

I am not sure if rebol serial ports do work without that. I wanted 
simply my rebol tool to find our device on whatever port (autoscan) 
and it imo hangeg the app, even if I used open/direct/no-wait

I used to do so for python scripts... it was really cool... no one 
saw the shell, until a crash occured, in which case all the prints 
where available for copy/paste.

My up cursor gives me an escape sequence on the screen in the rebol 
console.  How do I configure my console to recall the last line?

Do you see any text ?  Or, do you have to install some postscript 
fonts?

Do you have an idea of how hard it would be to do a port ?

Do you know how to print in Linux ?

How do you get browse to invoke the default browser?

I always thought it would be better to do the requester in rebol 
anyway, then we are all concerned to improve it.

Go for it.  I must admit Gnome and KDE are getting that 'smooth' 
feel.  What are us crusty old CLI coders going to do  :)

I think there's no need for that, however.
All you need to do is this:

then you symlink it in the /etc/rcx.d/ dirs (your distro will have 
ways to do this automatically)

but how do I acess files on drives other than the Root ?? (I am copletely 
new to linux, so bear with me if I am missing something completely 
obvious)

Hi Phil,


*nix doesn't use drive-letters, so _all_ drives show up somewhere 
under the root as directories. _Where_ they show up is up to you 
;-)

Drives are "named" /dev/hda1 (first paritiion on first disk), /dev/hdb3 
(third partitiion on second drive), etc ...

There's a file, which describes the mapping, where your drives are 
put, in Rebol

print read %/etc/fstab


the first two columns show where ich drive is put in the directory 
tree (and then some more info)

or you can do 

call "mount"

which displays the currently mounted drives.

Pekr; On my Debian system, I had to do an
  apt-get install libstdc++5
to get an older sdk version running.
I don't know Fedora's package manager but under Debian you would
  apt-get install libstdc++6
to get the shared libraries required.

Under GNU/Linux, having various shared libraries around isn't great, 
but it rarely hurts things.
the ldd command will show what shared libraries are required.

well, its not that we can't right now... like you show, load can 
be called anywhere.


 (though I am going to admit I would not have figured out such an 
 elegent way to do it, *I* am not yet able to use the force... <ahem> 
 parse with such skill, MASTER JEDI  ;-) ... 


but did you see how much is needed to make that work and the twist 
of redefining a rule within the evaluated expression?  parse is supposed 
to scream in speed... having a load directive integrated would be 
MUCH faster IMHO, and would be MUCH simpler for the new guys on the 
block and us oldies too...  try to explain the above to the average 
joe and well... there goes the parser...  I only 'SEE' your example 
cause I've become able to fit parser in my mind, and I realize that 
even within the advanced REBOLer crowd... not everyone really grasps 
the parser...


one question though, does the set [value pos] define the word globally 
even if the entire above code is within a context which has a value 
and pos defined?

do I need to return some value, or run cheyenne with some options 
?

If you are trying to run a CGI, best to do it with Core, not View
Looks like your script *has* started, but fails.

I've got this other little project to do.

but I want to do that on the box itself using Cheyenne.

brian, you can do like me, and just forward your address to gmail 
:) i did so for the spam filtering. and now i'm starting to appreciate 
the rest of gmail.

Things do seem to be getting better in email land.

My canada.com account I had delegated as the 'send spam here' as 
I got harvested when they changed to a new service.  Today, expecting 
to troll through the hundreds of viagra ads, I got none.

I haven't cleard the mailbox in a few weeks, and all I got was a 
job offer.  A real one.  This job was not for me, it was .Net related 
but no spam.  Hmmm.

I think gmail use humans as the training... any spam I get I tell 
the gmail about... thus with millions of users... they have a perfect 
trraining engine, which allows them to get only "real" spam and they 
probably just do a content match.

Gabriele, I've just been going through
http://en.wikipedia.org/wiki/Comparison_of_Linux_distributions


and I'm attracted to distros that aren't too far from a root distro, 
eg. Ututo based on Gentoo, or Ubuntu based on Debian. Also, I've 
tried Slackware on some older machines recently and it has spawned 
several distros, so Slackware might be good. I want to do audio work 
so I'll be looking for a kernel compiled for low-latency audio.

Linux DLL interface question: it looks to me, that if I declare


    settimeofday: make routine! [tv [struct! []] tz [struct! []] return: 
    [integer!]] libc.so "settimeofday"

and


    tv: make struct! [tv_sec [int] tv_usec [int]] reduce [seconds 0]

then

    settimeofday tv null-struct

works, but if I do instead:


    settimeofday make struct! [tv_sec [int] tv_usec [int]] reduce [...] 
    null-struct

, then it doesn't work. Can somebody confirm this?

anyway - it would be cool to have really small thingy, which is able 
to do webserving, proxy (eventually), sendmail .... well, as for 
webserving purposes, I can imagine very small distro, with just cheyenne 
and rebol :-)

I don't care about the firewall too much, because I don't want my 
server to do it at all - that is what is router and DMZ for.

Yes, generic servers make you do a lot of work for such things. SME 
Server and indeed ClarkConnect are custom-made for the things you 
want. SME Server has more integrated user management, but ClarkConnect 
is easier to put extra software on that is not part of the standard 
distribution

well, we will have the flexibility to do so being able to link INTO 
rebol.  but obviously not for the beginners.

Do I need to add my machine name to the users ?

My Windows 2003 server failed to update to service pack 2.  Either 
I find a way to revert the changes, or I need to reinstall :(

I'm thinking I should setup a Linux server and run my 2003 as vmware 
instead.  Anyone can suggest the "best" or "most" compatible linux 
platform? 

I do have Suse10 on another box and was running vmware server on 
it... but when I did some kernel updates ( I wasn't thinking ), it 
all stopped working and I have to reinstall the Suse10 again :(

Unfortunately, this indeed seems to be how it behaves from the command 
line. So you can't do that, or start it automatically, unless you 
never start it from the graphical desktop

It's a long-standing bug, and even the current Windows version seems 
to do something similar

Newbie to Ubuntu ... how do I install Rebol on Ubuntu s that I can 
double click on a .r file and it to run Rebol ?


I have downloaded the Debian version of View ... if I double click 
on the Rebol executable I getthe desktop .... if I then click on 
the Console the desktop dissapears but I dont get a console.
Any ideas ?

the thing is, one thing is to do it generally, because you don't 
have the energy for design, but another thing is to actually defend 
it as a good development method. that is why I think also that Linux 
as a desktop won't move forward. Perhaps now the best parts of Linux 
is actually what came out in the beginning, with the original GNU 
tools and not new tools being developed today.

I've been playing with Kubuntu on and off for a month or so. Sometimes, 
after updates to the system, something breaks.

I would like to know what is the best way of backing up and restoring 
the system.
I think the best way might be to copy partitions back and forth.
I have a few LiveCDs like the System Rescue CD.
What do you guys do ?

When you do a new installation, it's good to put your /home directory 
on a different partition. That way, you can backup just your data, 
or wipe the root partition and re-install the system withoug loosing 
your data and settings

That has been the way to do it for many years...

The filename "syncro.r" indicates that this file is of type "r document". 
The contents of the file indicate that the file is of type "plain 
text document". If you open this file, the file might present a security 
risk to your system.


Do not open the file unless you created the file yourself, or received 
the file from a trusted source. To open the file, rename the file 
to the correct extension for "plain text document", then open the 
file normally. Alternatively, use the Open With menu to choose a 
specific application for the file.

I'm looking to replace my mailer (The Bat! on windows) to a linux 
solution for ubuntu. what would you guys recommend? Claws? Evolution? 
Sunbird? Or something like mutt or pine? Or even some emacs solution? 
What do you think?

To help do the transition, I wrote a rebol script that converts a 
native The Bat! mail database to a directory tree structure mirroring 
the contents in the open Berkeley format,  mbox, as found in the 
Unix world.

But I want to do it a bit different these days. I want use a totally 
stripped down Debian with XEN support. Any further server applications 
like web-server, mail-server, xpeers etc. will go into one or more 
virtual machines.

Regarding EC2: yes, you have to do persistent storage outside of 
EC2. The logical choice for that is Amazon S3. You can install an 
S3 driver for the FUSE filesystem on Linux and use it transparently, 
if you keep the performance characteristics in mind

Syllable Server doesn't have graphics, sound, etc. beyond just the 
standard audio system that comes with the Linux kernel and the lightweight 
DirectFB and SDL libraries. You need SDL to run QEmu, which we include 
to do virtualisation. You can still run QEmu as a daemon and control 
it remotely, via VNC for example

Usually in this case, an older X11 library needs to be installed 
as well. But you can do:

I wanted to do some image processing.. I will have to write it in 
core than

I just downloaded vmware image of CentOS (based upon RedHat enterprise) 
and would like to run httpd automatically after my system starts. 
How do I do that? I can log into X, start services config tool and 
start httpd manually, but I would like to run it after the system 
boot. httpd is configured in /etc/rc.d/init.d/httpd .... don't remember 
where to put it to have it started automatically ....

Here under OS X, <Home> returns #"^A", so I can do this to use it:


view layout [key with [keycode: #"^A"] [alert "Home was pressed"]]

Anyone know what I need to do to get view running on Ubuntu 7.10 
?  libstdc++.so.5 is missing.  And sym linking to ibstdc++.so.6.0.9 
doesn't work.

If one wishes to run a View encapped application on a server distro 
of ubuntu, is this all one has to do http://softinnov.org/cheyenne/blog.cgi?view=0014
?

imho;  Ubuntu is the current up and comer.  Ubuntu ships with a defaut 
set of packages more tuned for running Gnome as the desktop.  Kubuntu 
ships with a default KDE setup.  The Ubuntu family is spin off of 
Debian ... Debian is my personal favourite.  The RHEL branches don't 
seem to do it for me quite as much.  Ubuntu is well supported with 
a growing community and a fairly well off benefactor.   Canonical 
is funded.  I'm pretty sure they still support the WeShipIt program 
where you can order CD's for free - shipping paid by Canonical.  
Pretty sweet.  But imho Debian is a little more solid; years between 
releases.  Canonical likes to stick to a 6 month updgrade schedule. 
 So you get new shiny every 6 months, but ... running a business 
on it, I prefer the soak time Debian affords.


GNU/Linux commands are fairly standard across the board.  It's the 
config, and helper apps that diverge the most.  (That alone causes 
a mess in GNU/Linux land but POSIX is POSIX).  Things don't really 
diverge low-level till you enter the other free unix clones like 
FreeBSD.  One thing to watch on the horizon is OpenSolaris.  If it 
rolls out as it should, it could well be the player to take in Linus. 
 And Ian Murdoch (the man beside Debra in Debian) works at Sun now, 
so ...


In short, Ubuntu good.   :)   But, I prefer it's parent, Debian. 
 If you check the IRC channels on Freenode, #debian is ruthless, 
brooks no guff, with awesome technical support.  #ubuntu seems a 
little more people friendly and perhaps more likely to effectively 
help new users.  Umm, don't go asking Ubuntu questions on #debian. 
 They seem to have a little bit of jealousy toward the younger upstart 
with all the flash cash.  :)


distrowatch.com will tell you pretty much anything you want to know.

Oh, and if do have a spare hour or two, don't forget to test Syllable. 
 There is a group here for it.  Some of the principals of Syllable 
development are rebols at heart.  :)  The Desktop can be tested from 
a Live Boot.

Crappy.   I had Kubuntu 6 Live do that on a lot of the machines I 
tried, but that was X and the mouse duking it out.  Never had a Debian 
install fail, but I have had to boot single user to tweak X11 config, 
but that all went away with the transition to Xorg.  ... knocks on 
wooden brain ... so far.

I justed installed Kubuntu on this machine BUT the installed leaves 
a lot of room for improvement.If I had never installed a Linux distro 
before,Kubuntu for the normal Windows user would have them saying 
"f*** Linux. The install gui does not have a progress bar and when 
it is done installing, it does not let the user know the install 
is done and what to do next :( Mandriva on the other hand has an 
excellent install gui. If the major distros could work on a unified 
install gui it would be worth its weight in salt. I did see an effort 
to that end by 2 different ppl but they can not work together because 
of design/programming ideas :( Linux on the desktop works well once 
installed/configed but still it not made for joe six pack

yeah; one of the last frontiers; ease of use.  But it is progressing. 
 It's a little bit too sad that the y2k thing gutted IT money (not 
that the whole .com thing didn't need a good slap to the face) but 
there were some corporate players taking all their funny money and 
setting up OSS departments.  That died an untimely death imho, while 
corporate got mad about spending billions to protect against fudiciary 
responsibility around legacy code and then got nothing in return. 
 No more funny money for the IT department ... since?  So now we 
rely on one of "us" to get the itch and dig in.   Some do.  But it 
is time consuming and somewhat boring clicking through the same installer 
screen 1000 times to cover (some fraction of) all  the bases.  :)

Yeah if you do go bash, (I'm not sure how you get your file list) 
ls -F will append @ to links instead of looping over test -h

or do I need to use a shell script ?

Yes; there are quite a few ways to secure Secure Shell ... but you 
do have to stay on your toes.  Just turning it on ... bad idea.  
;)  With most distros that is ... Cygwin included.  There are copies 
that default to lockdown and you have to work to open them up, but 
those are the exception still.   Assigning ports above 1024 is always 
smart, and the $40 firewall routers can easily be setup to forward 
port 22 or 80 etc, to a usermode port.  You might still get broken 
into, but at least not with root access.  And hey, iptables is fun 
stuff.  Light reading.  :)


And, just because I'm being gabby ... rsync is a wonderful tool if 
you have multiple nodes and want hot backups.  This article expalins 
how to set it up, and while doing so, explains setting up ssh keys 
and locking things down.
http://www.debianhelp.co.uk/rsync.htm

btiffin, ok, so using a key with ssh looks like a good thing to do 
then. It's on my list.... :)

Thanks but this isn't really such a great piece of code (Windows 
API is doing the real job), even if it fills a gap in REBOL (at least 
for Windows). Btw, in my company, we're using Gab's pdf-maker for 
years now to generate and print all our documents. I made this library 
only because I needed a direct printing solution for a customer and 
I must admit it was a fun work to do.

But this is the merit, everybody could do it (OK almost everybody, 
not me for example), but you did it.  Printing points up dual problem, 
first it is definitely against Cross-platformity, but second if anybody 
intents to work seriously (make real aplications) definitely need 
it.

who wants to clone Crystal Reports ?
  

We would need a /bloat refinement to do that. :-)

That shouldn't be hard to code in PS. Anyway, now I just need to 
code it in Draw, and let the printer:// scheme do the work.

What I tried to do was create a print template that the user can 
define.
