Hi Nick: The arrangement that has been discussed between Carl S, myself and the owner of the server that I lease would be to host the ML on my server, under my domain. With the current traffic level, or even somewhat greater, there would be no cost. The list traffic from that server would then be redirected thru the current node, and I don't even think the address would have to change.

I had some domains on Hostmonster at one time. With one account, multiple domains could be hosted, but there was no seperation of permissions, which made it useful only if one hosted one's own domains.

It now looks like the ML is now (for the time being) recognizing me. -- In the 10 years that I have been on this mailing list there have been frequent outages - this last one was for over a week. That doesn't do the rebol community any good - and can certainly turn off prospective/new users. We have discussed in the past, using google groups. Carl has opposed that because he wishes to have intellectual property rights to the mail. Apparently google would claim that right. I would like to offer to host the ML on my server. My server is co-located with cniweb.net. In the 9 years that I have hosted domains and other service with cniweb, they have never interrupted service. Their technical support is top-notch. Their owner, Corey Johnson (no relation) is always right on the mark. Furthermore, Carl will have full property rights. I want to say also, that cniweb has been rebol-friendly in all ways from the very beginning No strings attached. Let me know. We can make this happen later in this week or the next one. One caveat.

On Thursday 12 February 2009, Henrik Mikael Kristensen wrote: The issue has been well known to RT for years: Linux is the hardest OS to support due to its very non-standardized nature. There are constant kernel and library changes. But RT usually asks regularly what people use the most, and then compile versions of REBOL to that Linux variant. The question was in fact asked again a few days ago, when the R3 version was going to be built. The answer was Ubuntu and an Ubuntu version was built. We've never had such problems with python or perl. We have never had to build perl or python on our machines. Although I have built newlisp. Thusly, I believe you are overstating the variance among linx distros. It has been a long time since I programmed in C and had to compile, but I believe a strategy for more flexible loading or static linking exists. Furthermore rebol 2 should be compiled for 64-bit. The year I started coding for compensation - 1989 - was the year of the Ashton-Tate dBase fiasco. And I was programming in dBaseIII+ and dBaseIV. I quote from the Wikipedia entry: a focus on future products without addressing the needs of the current customers. There's a cautionary tale there. I am glad that you are building for ubuntu. You should take great effort to ensure that rebol is in the repositories and that it includes a nice application of some sort. I would like to test such a build. If you are part of the development team did you see my email of Saturday 07 February 2009, subject Re: Inside R3's developement...? I am very concerned that no one replied to my problem there. Rebol has served me, my company and my customers very well for 9 years. It is a pleasure to work with and at least 50% more productive than python or perl in small, single-programmer projects. Even tho' I use it as the critical part of my productivity and production tools, I've stop doing any development for customers until a mature rebol with 64-bit compatibility is available. A 64-bit rebol 2 should have been built long ago. If but a few server farms start converting to 64-bit and rebol binaries become inoperable, there will be such a stink that rebol3 will never overcome.

Hi Mario: I'm Cc'ing this reply to the rebol mailing list, because frankly, the lack of concern showed regarding this issue is disturbing and the rebol community should have this stuck in their face.. On Wednesday 11 February 2009, you wrote: I've followed your description of running the Rebol on 64-bit Linux, but couldn't make it happen due to my insufficient understanding. libm.so.6 = l1bm.so.6 libc.so.6 = l1bc.so.6 ld-linux.so.2 = ld-l1nux.so.2 and made copies of the shared objects with those name changes, ported all to the ubuntu machine and I have rebol running. You can try getting a copy of 32-bit libm.so.6, renaming it to l1bm.so.6 and putting in the same directory (presumable /lib) - then do the same for libc.so.6 and ld-l1nux.so.2. So now you have /l1bm.so.6, /l1bc.so.6, ld-l1nux.so.2 Does that make it clearer. I did correct the paths using the vim -b mode, but then I didn't understand the shared objects and porting. Anyway, the question I have is whether it is possible to have a Rebol 276 running on a Debian 64-bit (Lenny) platform and how can I achieve this? I ended up going back to 32-bit ubuntu.

[REBOL] Re: HTTP Silent Redirect
On Monday 22 September 2008, [EMAIL PROTECTED] wrote:
Hello Rebol List,
I'm attempting to do a silent http redirect via REBOL
rather than an Apache mod_rewrite.
In Apache it could be written as:
RewriteRule ^secret_crush_prank/?$
/var/chroot/html/go/secret_crush_prank.html [NC,L]
If the client visited http://www.domain.com/secret_crush_prank
the client would be silently redirected to another page without
seeing the new URI location in the Address bar of the browser.
Hello Vonja: I'm not sure just what your end use is, and I'm a bit
confused about what you mean by silent redirect because to me
the term seems to be an oxmoron. So follows two code snippets:
one for a redirect: ( in python, but easy to translate to rebol)
def js_redirect(S,emit=None):
Compose a javascript redirection.
R = 'SCRIPT language=JavaScriptwindow.location=%s/script' % S
if emit: print R
else: return R
that should translate to something like (untested)
reb-redirect: func[URL][print rejoin[{SCRIPT
language=JavaScriptwindow.location=} URL {/script}]
But if you were doing something like a silent get url - like the
silentposturl method used by credit card authorizers, as an example -
here's an idea employing the rebol command line and another script
on my desktop:
res: read
http://bart.johnson.com/cgi-bin/baker/reb/baker.r/execute?task=List-Queries
;;Capturing the output from the script in the 'res variable suppresses any
;;output
and if I look at baker.dbg (the debug log for baker.r), I see that both the
'execute' path part and the 'task' name/value pair have been logged.
Does either of these help?

This worked great for the sample data set of 45 MB. this then failed on a 430+ MB file. i.e.. data: read/lines %file-name.log I then changed the direct read to use a port i.e.. data-port: open/lines %file-name.log.

Are there any suggestions? My guess is that I will need to; - pull in a fixed length block of data - read to the data until I reach the first occurrence of a newline - track the index of the location of the newline - continue reading the data until I reach the end of the data-block - once reaching the end of the data retrieved, calculate where the last record process ended - read the next data block from that point - continue until reaching the end of file Any other suggestions?

Sadly, I don't think are any DSL lanuages (in the classic sense) which are considered mainstream.

[REBOL] MySQL driver - trap warnings
Hello rebelers: My second favorite programming language is python :-) The python DB api for mysql has a feature that reports warnings from MySQL. I haven't used net-log, not sure how it works but I see from mysql-protocol ver 1.1.1 that DocKimbel is employing it. Perhaps it would be a good addition to a wish list to trap warnings, possible via net-log. Thanks Tim -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
