Both the public beta of /View and the current rlse of /Core blew up instead of running. Yes, that's the demo effect! :) I hope you tested rebol on that machine _before_ the demo... I didn't report it at the time because the box was Debian Unstable, and assumed that maybe the guy who set it up was just a little too close to the edge. Since then, I've seen traffic on this list indicating that others have had problems with REBOL on Debian, so perhaps my experience wasn't so unique or box-owner-dependent after all??? Yes, problem was the guy running the box, not Debian not even it's unstableness. The root of the problem lies in rebol using an _ancient_ library called termcap. Debian does not have this library in it's normal distribution but in _oldlibs_ as it is very old it is compiled against libc5. As other libraries and rebol are compiled against libc6 and those two don't mix the crash occurs. The guy running the box just has not removed the old libtermcap. He surely has no programs depending on it anymore. The workaround is to remove the libtermcap and make link from libncurses to libtermcap. So, it is not Debian's fault that the guy wanted to keep an old libc5 library installed. Sure Debian is somewhat harder to install than RedHat. But it has some other virtues (atleast for power users and opensource enthusiasts). And for my part, no I was not up for the task either and had libtermcap installed once, but that has been long gone. I surely wondered about the problem for a long time. I would suggest REBOL to include a warning to the readme on this. It seems that a lot of people have debian installed with the libtermcap.

[REBOL] REBOL does not work on Debian Linux 2 2 Re:(2)
Quoting [EMAIL PROTECTED] ([EMAIL PROTECTED]): Hi, long time ago I had mysterious segmentation faults in Debian. I am no Linux expert, but it was some problem with libc5/libc6 incompatibility. Yes, they don't mix. If they are linked to same program the program dumps a core. I'm very disappointed with Linux shared libraries compared to Amiga's. If Linux developers make everything dependant on everything and can't guarantee backwards compatibility, I'd rather use statically linked executables. Libraries on Linux are different from Amiga, but they are not that bad once you get used to them. The main advantage over Amiga libraries is that you can easily have several versions of libraries on same system and when properly used and the system is installed correctly they don't interfere with each other. You could not do this on Amiga always when updating libraries one risked the stability of the system. All Amiga libraries were not that good on compatibility.

[REBOL] Network related problem with the Experimental releases
Hi, I am suffering with a problem with the experimental releases of Rebol. I am unable to read data over HTTP from anywhere but my own domain. I have tried to tweak with the proxy settings, but with no success. I am hoping there is something I have overlooked and someone on th list could give me some assistance. I am also cc:ing this mail to [EMAIL PROTECTED], although I have reported this problem also earlier. With Core 2.3 networking works without a proxy. With proxy set works HTTP fine. FTP, FINGER and maybe some others don't. This is of course not a big problem as it is possible to specify different proxy servers for different protocols. Netscape works though fine with FTP. Using Experimental Core without proxy allows me to read files only from this domain (abo.fi) no other that I've tested works. FTP works fine without proxy. If proxy is on I can not read files over http even from this domain. Also FTP is not working but this was expected. Something has changed between the released versions and the experimental versions. As one works and other don't. I have tested this program on Linux (libc6), Windows98, BeOS and FreeBSD. All tests were on this same machine and gave same results. At work experimental version of Core works like a charm. If any of you have any ideas to solve this problem it would be great. Yours, Jussi P.S. Enhancement request: Would it not be possible to determine the type of proxy automatically? I have not had to know it for installation of any other program. It would make installing rebol easier for common users. -- Jussi HagmanCS in Åbo Akademi University Studentbyn 4 D 33 [EMAIL PROTECTED] 20540 Åbo [EMAIL PROTECTED] Finland

So the problem seems not to be just with proxy but with REBOL. Some more

Hi, After coding on the C64 and before hitting the bed I'll write quickly... Quoting [EMAIL PROTECTED] ([EMAIL PROTECTED]): Another idea that was brought up was that you could have more than one view of the command line args available, so those that want the separation of args would have it in a block somewhere, and those that want just a doable string would have it somewhere else.

To get the arguments in a block has definately it's uses. And there is no idea giving arguments in some rebol-specific way, as you suggested earlier. About doable arguments, you said (I already clipped that part away, sorry) that it is inefficient, maybe so but the args are parsed only once and starting rebol takes it's time anyway...

[REBOL] Text to CW !!!
Hi,
I saw a perl script in USENET news that coded text to CW -alphabets,
the author of script challenged others to do the same with a shorter
program. I thought to do it in REBOL. Here it is, much shorter than
the original perl -script, that was actually very badly written, but
unfortunately a bit longer than the shortest (and very unreadable)
perl script. This script is a bit broken (because I tried to take
every byte off that I could). And almost unreadable. It is certainly
not a good example how one should program in REBOL. I post it
here just because there might be some interested in it. Here it comes
(about 210 bytes :)
REBOL[]foreach c system/script/args[s: copy{ }x: index?
find{etianmsurwdkgohvfüläpjbxcyzqö*54*3***2***16***7***8*90}c until[s:
head insert s either odd? x["."]["-"](x: to-integer x - 1 / 2) = 0]prin s]
And a little more readable version:
REBOL[]
foreach char system/script/args [
str: copy " "
pos: index? find
"etianmsurwdkgohvfüläpjbxcyzqö*54*3***2***16***7***8*90" char
until [
str: head insert str either odd? pos ["."]["-"]
(pos: to-integer pos - 1 / 2) = 0
]
prin str
]
It is supposed to be used from the commandline, but it is easy to
alter do otherwise. I'll repeat this, if you want to use this code
snippet in your program do yourself a favor and fix it, currently it
is hmm... feature rich :) It does not like spaces in input and
also unknown characters produce a crash.
Have fun,

Quoting [EMAIL PROTECTED] ([EMAIL PROTECTED]): Hi Paul, you wrote: At the sametime I'm thinking of BEOS. They have a beautiful product but their pricing is keeping the OS out of the hands of the people that could make it a player. I may be wrong but I don't think BEOS will ever be a contender simply because the owner is so intent in making money from day one. Actually, if I recall correctly, their pricing is relatively low. Correct me if I'm wrong, but I recall having received an email from them, when their Intel version began shipping. The price I believe I saw then was about $40 - $60. Have they raised their prices since? I find BeOS pricing quite accepatble, they are selling a bundle of the operating system and a book called BeBible for $80. OS without the book is $70. I checked pricing in Finland and noticed that BeOs is priced a little below Windows 9x and considerably below Windows NT/2000. So I'd say that Be is probably not making so much money out of their OS, just trying to get their expences covered.

[REBOL] [REBOL] Recursive data structures Re:
Quoting [EMAIL PROTECTED] ([EMAIL PROTECTED]): I need some help about recursive data structures (stacks, queues, trees, etc) Which is the best method in Rebol for the creation and manipulation of these structures? Example: The following is a simple C code for insertion and deletion of stack elements. How can be rewritten in REBOL? Why would you want to implement a linked list in REBOL, when there are integrated types BLOCK and LIST. So an easy implementation of stack or queue is just to manipulate a BLOCK. I see no need to reimplement a linked list, you probably wouldn't come even close to the native implementation of LIST or BLOCK. If you want to have a binary tree you can implement it as nested BLOCKs. For example following tree 1 / \ 2 3 / \ 4 5 can be expressed as [1 [2 4 5] 3] (that's [value left-sub-tree right-sub-tree]). Functions to manipulate it should be quite straightforward to implement (Haven't tried :).
