[REBOL] interacting with forms

[REBOL] time function

[REBOL] FTP problem Re:
We don't yet support using FTP proxies. The problem is that many (if not all, I don't know) FTP proxies return HTML rather than normal FTP responses. This causes us a problem for parsing that HTML since it can be totally different for each proxy. Sterling Hi, I once more tried to use the ftp stuff from Rebol. I'm using a dialup connection. For this I connected to the internet and tried to read the root directory of my ftp server, which gave the following error: read ftp://openip.org connecting to: openip.org ** User Error: Server error: tcp 500 Bad username format - format is user@host:port. ** Where: read ftp://openip.org I tried all kind of combinations of user:psw@host etc. with and without the port no success. I'm using an FTP proxy and have configured in the following way: system/schemes/ftp/proxy/host:"localhost" system/schemes/ftp/proxy/port-id: 21 system/schemes/ftp/proxy/type:'generic I can see that a ftp session is established but nothing happens. Any idea where the problem is? Robert M. Muench, Karlsruhe, Germany == ask for PGP public-key == When do you want to reboot today?

[REBOL] Web Hosting Sites that support Rebol? Re:(6)
I am still confused ... when you say "I had to upgrade my server in order to run Rebol" what does this mean? Do you have a separate physical machine located at their physical site which they maintain and do the admin work for - in this case, I understand, although I suspect that's a bit expensive. Or does it mean you get a separate copy of the server software on a shared machine and this gives you more extensive control of the server configuration than is available with most web hosters? I am not as familiar with this type of hosting arrangement, and would like to hear more of the details. Thanks.

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.

[REBOL] clean-path when arg is url? Re:(2)
Well, the reason that clean-path does not clean up URLs is that you may want that information. Take, as an example, FTP. For a file on your hard drive, the path: %/../../foo/bar/baz is the same as: %/foo/bar/baz zso clean-path can clean that up without loss of information. However, the URL: ftp://my.domain.com/../../foo/bar/baz may not be the same file as: ftp://my.domain.com/foo/bar/baz because my home directory may be in /home/me so I am really accessing a totally different file in the two cases. It is dangerous to play around with paths when you could be sitting in a virtual root directory but still with the ability to go back to the real root. Sterling Hi Joel, Not sure why clean path is limited to non urls. Why not put in a request for it to be modified, to [EMAIL PROTECTED] ? In the mean time there is function to clean http paths on the Rebol Examples page http://www.rebol.com/examples.html Clean HTTP-Path "To remove /../ from within HTTP URLs.

[REBOL] Round function Re:(5)
Larry wrote: Maybe one more small refinement? The way I learned to round is to round to nearest (as your function does), except where the least significant digit is 5. In that case, one should round even. For example: 1.4 rounds to 1 1.6 rounds to 2 1.5 rounds to 2 2.5 rounds to 2 3.5 rounds to 4 This extra step helps avoid bias when rounding a sequence of numbers which end in the digit 5. Otherwise the sum of the rounded sequence is not equal to the sum of the unrounded sequence. Another way of avoiding bias is to randomly round up or down when the last digit is 5. I think your system might be mistaken as it doesn't take into account the rounding of .0 1.0 1This is part of the sequence. 1.1 1 1.2 1 1.3 1 1.4 1 1.5 2 1.6 2 1.7 2 1.8 2 1.9 2 etc Of course, I could be mistaken.

[REBOL] Imperative vs. Functional Re:
Hi John, 1. The examples and scripts submitted to REBOL reflect the preferences that the most active REBOL programmers have acquired over years of imperative programming. Unlike other functional or hybrid programming languages, REBOL has rapidly attracted a surprisingly large following of mainstream programmers and as a result - no matter to what degree REBOL may encourage functional programming - these programmers bring their skills to REBOL, albeit imperative skills. 2. Recall that we have seen a number of users report that as they start scripting in REBOL, they automatically attempt to think of their program in terms that they have become used to based on their former programming experience. These same users also reported that after a short time they learned to see things the REBOL way, and judging from their messages, they felt it was a superior way of formulating solutions. Apparently these users where able identify their initial imperative view and recognized the merit of functional facilities provided by REBOL. Here REBOL's hybrid character proves itself useful in allowing the individual programmer to define the speed at which he is comfortable migrating from an imperative to a more functional paradigm, if he chooses to migrate at all. 3. The categorization of a programming language announces the kind of programming constructs the language supports to its potential future users and therefore should be based on the facilities it provides - as evidenced by its syntax and vocabulary. To describe a hybrid programming language - with a strong bias towards functional programming - as imperative, based on the choices its current, most active user base happens to make, is "disingenuous". Elan
[REBOL] Imperative vs. Functional Re:
My point is not that REBOL cannot be used for functional programming. Nor is it that functional programming languages cannot have imperative operations. My point is that describing REBOL as a `functional' language is disingenuous because, although it can support `functional' programming, it encourages an `imperative' style. The vast amount of `imperative' code present in the examples and the script library are evidence of this bias. It's enough I think, no? I remember similar discussion on this list some time ago, lead nowhere. It's starting to sound as opinion vs. opinion and noone seems to be willing to accept argument of opposite side. So, while the discussion can be informative for us all, maybe it's better to stop it to prevent us from flames.
