Do anybody else agree with me? :-) Actually, I do. The concept of relativity goes back to Gallileo (the mathematical device for converting from one frame of reference to another is called a "Gallilean transform"). The key insight of Einstein's theories is the identification of WHAT IT IS that every- thing else is relative to. I have read that Einstein considered calling his theory "The Theory of Absolutes" precisely because the central issue is that the speed of light (and NOT some priveleged spacetime coordinate system) is the absolute for the issues he was investigating. Enough rant. The real point is that the phrase "everything is relative" has been so abused by our short-attention-span popular culture that many thoughtful people of my acquaintance find it annoying or distasteful. By analogy, the concept of separation of authority between federal and local government is fundamental to the U.S. Constitution. However, the phrase "states' rights" became so thoroughly associated with a particular position -- opposition to the civil rights movement -- that its connotations outweigh its literal meaning and it has almost disappeared from common use.

Hi Steve, What I've done is certainly NOT something one could slip into an application and have the full functionality of TCP/IP/SLIP (or PPP) for client and server that you seek. Sorry if I seemed to imply that. What I have done, mostly to see what could be done and to learn the raw elements of PPP/IP/UDP/TCP, was to program PARTS of these variously in VB, C and Assembly language and test them on a Win/PC, Linux and a PIC16C84. I began with PPP and cut many corners (my versions certainly would NOT connect to every ISP going, nor handle all authentication/compression conditions/options). But I did get a PIC to dial the (external) MODEM and connect to a few ISPs (some more reliably than others). I then verified that ICMP worked (handling system events and doing things like PING). It was quite exciting to see the first PING reply come back from a distant node on the net! :) I added some IP capabilities so that I could test UDP and TFTP. Basically, I put in only enough to get to the next step, not to meet any particular or rigid specifications or to create general API functionality. I began elements of the TCP stack (enough to say there was one present) but ran out of memory, time, interest, and motivation :) I'd learned what I wanted to: that a small PIC chip was probably inadequate for the purpose. But also that one did NOT need a Pentium and Windows (or even a 386 and Linux) to do networking. I hope the story is a bit interesting to you, but sorry I cannot offer anything concrete for you to drop into a real micro/networking application. I think we're both at about the same point and looking for the same things :) Might I ask what SLIP/IP/TCP stack you've used that's 42k? Is it generally available? Re emWare, as I see it, it simply pushes the problem from one place to another... admittedly to a larger computer where it's more easily solved. But that seems like "cheating" to me ;) Although you may already be aware, I pass on these reference for you or anyone who's interested in these topics (these are not meant to be exhaustive, inclusive or anything other than interesting): http://www.circuitcellar.com/eiw_proc/98ewi/proceedings.htm http://www.circuitcellar.com/pastissues/articles/Tom106/text.htm http://www.chipcenter.com/circuitcellar/july99/c79bl1.htm http://www.picoweb.net/ http://www.circuitcellar.com/pastissues/articles/Loewen108/Loewen-108.pdf I was in correspondence with the author of this last article, and we were both pursuing something very similar at the same time. His published article might spur others interested in networking tiny processors. You'll get an idea of the corners that must be cut to accomplish such feats with limited resources. And also why I've decided that for many/most applications of interest to me, I'd prefer greater capabilities... like using a high-level language, more advanced processor... but NOT to the extent of today's full-blown PCs and O/Ss. I think the small footprint, integrated networking, and powerful/flexible syntax of REBOL has attracted a number of us "low end" application people, in the hope that it might offer the best of many worlds for our applications.

Martin, You're quite right that many 32-bit CPU's have dropped considerably in price.

There is no absolute space or time, and even if any observer would explain the universe with the same law, each observer would see a "different" universe.

Sure, we all have our visions, but trying to sell a product from this kind of claim is not fair (nor honourable), IMHO. Anyway, I did mean the sentence "sorry about having that opinion", as I know it's probably of the deepest irrelevance to the great people at REBOL Tech. Anyway, now I've had room for my frustration ;-) BTW, if REBOL Tech. _do_ want to cite Einstein, better make it "Everything should be as simple as possible, but not simpler".

[REBOL] Declaring Arrays Re:
Hi Phil! [EMAIL PROTECTED] wrote: Is it possible to use a variable to declare the size of an array ? my-array: array [3] I see your problem right here. You don't declare arrays, you create arrays, like this: my-array: array 3 == [none none none] Note that array is a function, which can take any integer or block value as a parameter. To use a variable you do something like this: j: 3 ; Assigning 3 to j (no declaration needed) == 3 my-array: array j ; A function call, not a declaration == [none none none] my-array: array reduce [j] ; reduce needed to evaluate j here == [none none none] my-array: array [3 3] ; multidimensional == [[none none none] [none none none] [none none none]] See?

[REBOL] Extraction Re:
Hi Chuck, I'm just going to point you in the right direction, without giving you a precise answer, as I believe everyone who wants to get the most out of REBOL needs to take the time to learn the power of Parse. So your answer lies in here http://www.rebol.com/user-guide/parse.html And here's a hint data: copy "" page: read bigpage.html#section1 parse page [skip thru "!-- content block A --" copy data to "!--end content block A --"] write/append destination1.html data Cheers, Allen K -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, 29 October 1999 5:11 AM To: [EMAIL PROTECTED] Subject: [REBOL] Extraction Howdy, I'm trying to figure out how to extract blocks from one file into their own respective pages.

My bigpage.html file has about 180 content blocks, and those ~180 content blocks need to be extracted to 12 different destination pages.

[REBOL] New REBOL Dictionary, Beta 2.2
A new REBOL Dictionary has just been posted to our site. Thousands of changes have been made. New words, new descriptions, new examples, new links, and much more. http://www.rebol.com/dictionary.html (374K) Or, you can download the REBOL compressed version: http://www.rebol.com/dictcomp.r (82K) If you find errors, let us know at [EMAIL PROTECTED] We still have additional improvements that we want to make, but we didn't want to delay publishing what we've got. We will also be adding new index tables that will include only words for particular categories (like the old Alpha version of the dictionary). -Carl

REBOL *must* be basing dates on a stored Julian day number. They should give us a word 'julian that returns the julian day no for a given date, and some other word to convert it to a date. The Julian day number accounts for leapyears, number of days in each month, etc. There are a number of "epoch" dates corresponding to Julian day number zero.
