[REBOL] XML-RPC
I wrote a paper on XML (Extensible Markup Language) for: http://www.chipcenter.com/circuitcellar/february00/c0200r30.htm Why would we here care about a thing such as XML? The article covers such things as XML-RPC which is a Remote Procedure Calling system, and Distributed Objects. Any one want to run a big job on lots of computers using Rebol maybe? :-) Alas I wrote this paper in early December before I started using Rebol, would have been good to get it in the article. -- What is XML-RPC? XML-RPC is a Remote Procedure Calling protocol that works over the Internet. XML-RPC Specification: Simple cross-platform distributed computing, based on the standards of the Internet. It's a specification and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet. It's remote procedure calling using HTTP as the transport and XML as the encoding. It's designed to be as simple as possible, while allowing complex data structures to be transmitted, processed, and returned. An XML-RPC message is an HTTP-POST request. The body of the request is in XML. A procedure executes on the server and the value it returns is also formatted in XML. Ken MacLeod has more about XML and Distributed Objects on his site. SAX 1.0: The Simple API for XML SAX 1.0: a free API for event-based XML parsing. SAX is a standard interface for event-based XML parsing. What is an Event-Based Interface? There are two major types of XML (or SGML) APIs: tree-based APIs; and event-based APIs. A tree-based API compiles an XML document into an internal tree structure, then allows an application to navigate that tree. The Document Object Model (DOM) working group at the World-Wide Web consortium is developing a standard tree-based API for XML and HTML documents. An event-based API, on the other hand, reports parsing events (such as the start and end of elements) directly to the application through callbacks, and does not usually build an internal tree. The application implements handlers to deal with the different events, much like handling events in a graphical user interface. If your XML document were 20 MB large (or even just 2 MB), it would be very inefficient to construct and traverse an in-memory parse tree just to locate this one piece of contextual information; an event-based interface would allow you to find it in a single pass using very little memory.

[REBOL] WebCam CGI script Re:(11)
Some of the available free Unix's are: Note that the following NON-COMMERCIAL versions of freebsd, openbsd, and netbsd are all open-source - you get the source code with the O.S. for free. FreeBSD at http://www.freebsd.org - this is the one that runs sites like Yahoo, etc ... and the closest thing to the actual Berkeley Unix. The book, "The Design and Implementation of 4.4BSD Operating System" can even be used as a reference guide to the internals of this operating system. It has complete SMP support. This one is targeted squarely at x86 systems, only. OpenBSD at http://www.openbsd.org - this one is targeted for secure environments. The entire source was subjected to a 10 person, 1-1/2 year audit for security issues. Considering the latest attacks, if security is of concern, this is probably the guy to have. This one, is multi-platform. NetBSD at http://www.netbsd.org - this one is targeted for cross-platform support, and probably is implemented on more platforms than any other Unix known, bar-none. The commercial "version" of BSD is at http://www.bsdi.com - this one runs Thunderstone software (http://www.thunderstone.com) for ebay, and http://www.zdnet.com, probably the two busiest sites on the internet! In fact, this version probably supports most of the BIG commercial sites on the internet. The cost of this O.S. is based on traffic. An unlimited traffic license will set you back about $3000.00 for binary only and $5000.00 for source and binary. Full SMP (of course), with just about every IP-control bell and whistle possible. An all-in-one ISP package, for sure. -ron At 12:54 PM 02/12/2000 , [EMAIL PROTECTED] wrote: They don't currently run Rebol as Rebol didn't run on their operating system when last they checked.

[REBOL] Assurance of portable rebol scripts
Dear rebolers Before I start I would like to say how much I am enjoying rebol and seing how it can solve pratical web programming problems in a simple manner. So far so good. The rest of my email seeks to stimulate some debate on some of the trust/security issues of mobile code. What is the perceived model for assuring rebol scripts as they fly 'round the web doing their clever messaging and powerful programming thang? Certainly the problem of mobile and possibly malicious code hasn't started here (ActiveX, javascript etc), although isnt the inbuilt networking capabilitie one of the selling-points of rebol. Ergo there needs to be a model of how we can make best use of the technology, whilst maintaining a certain level of trust in the software as we download and run it. I see two possible limitations within the current rebol programming space as currently defined (please correct me if I'm wrong): 1. Rebol scripts are text-based and interpreted. As well as this being a great feature in terms of portability etc, it is also a limitation in as much as it means scripts can be easily altered, possibly in a malicious manner as they flow around the internet. At least with standard programs there is less of a risk of reverse compilation and modification. 2. There is no interface to external modules (e.g. native applications, the command-line etc). In the pursuit of cross-platform portability perhaps - it has been decided that there is no native interface to third party modules written in other applications. This means it will be difficult to digitally sign rebol scripts (e.g. PGP?) to ensure they are received as intact and as the author intended. Just think of the damage caused by melissa and her ilk - what might be the analagous scenario in rebol - is it conceivable?? How do we convince the corporate world that there is a solid security model behind the rebol approach? in anticipation, Luke Emmet
[REBOL] Your invaluable assistance Re:
Hi Tim, I enjoyed reading your description of your personal history and your project. I don't know very much about web programming, but I'll help when I can. You wrote: P.S. I've got some ideas for a rebol "librarian", that could fetch reusable subroutines like the one the Eric wrote, and insert them into a project file. More about that later. I'm not sure how necessary a project file is for REBOL programming, at least at this stage. I never got to the point in C where I needed a project file, but my understanding is that project files are handy to speed up the process of compilation (so that you don't have to recompile files if their code hasn't changed), and to link in compiled libraries. I think with REBOL you don't have to do (can't do) anything more complicated than including files. A lot of us have written utilities for this. I have one on rebol.org called dore.r that is a big help. It indexes all the *.r files below the REBOL home directory. Then you can do my-script.r with just: dore my-script; takes a word! argument and, dore/maybe my-script will do that script only if it hasn't been done. This is the statement I use as an equivalent to an include statement. Also, dore/list my-script will print out a list of functions and objects defined in that script. I could send you the latest version if you're interested. See you, Eric

Great, someone who knows about XML and REBOL! I have just begun researching XML and was thinking about how it relates to REBOL. Can REBOL be used in place of XML? I would like to hear other's thoughts on the matter. Here are my comparisons for some of the 7 points about XLM listed on http://www.w3.org/XML/1999/XML-in-10-points 1. XML is a method for putting structured data in a text file REBOL can be used in exactly the same manner. 2. XML looks a bit like HTML but isn't HTML Looking like HTML is a bad thing in my opinion. Having to match the word of start and end tags is brain-dead. It takes more space and makes it inconvenient to change tag types. REBOL's open brace/close brace is as clean as you can get. In my text editor I can easily find the end of a REBOL block by using the 'jump to other bracket' command. 3. XML is text, but isn't meant to be read Unlike XML, REBOL claims to be readable by non-experts. I'm not really sure if REBOL can live up to this claim; it is a computer language and uses punctuation in 'weird' and very specific ways. However I think it is a noble goal to strive for. 4. XML is a family of technologies Are the examples given (Xlink, XSL, etc) equivalent to REBOL dialects? REBOL seems to be its own "family of technologies." Witness REBOL/View, REBOL/Command, etc. Extensions and dialects are created in REBOL itself. REBOL/Command seems to be the equivalent of DOM. DOM is described as "a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents". If you're scripting you'll be using REBOL itself to do this job. From compiled languages you'll access REBOL scripts and databases via REBOL/Command. Will Command be usable for compiled languages other than C/C++? 5. XML is verbose, but that is not a problem This point talks about how the text format of XML is larger than binary formats and how with compression and large hard-drives this isn't an issue. The same applies to REBOL, but even more so since it is less verbose than XML. 10. XML is license-free, platform-independent and well-supported The most important statement in point 10 is "The large and growing support means that you are also not tied to a single vendor." REBOL Technologies is trying to be platform independent by producing binaries for popular platforms, but this is no substitute for being free and open-source. REBOL/Command is a most vital REBOL component and may not be freely available as REBOL/Core is. Once you've chosen REBOL you're committed big-time. -Karl Robillard
[REBOL] hostname parse rule

Your name-rule requres a let-char then it permits for none and then goes to end.
