[REBOL] Automation query... Re:
Hi TBrownell, you wrote: Hi. What is the best way to run a script on a timer basis? I have a script that that fires off another that checks a pop account every minute and then runs any scripts it finds. This is a bit thick, but it works... N: repeat 100 [wait 60 do %popreader.r] You can use forever, i.e. forever [ wait 60 do %popreader.r ] This is lacking as... A. If it hits an error it stalls. use try, i.e. forever [ wait 60 if error? set/any 'error try [ do %popreader.r ] [ date: replace form now "/" "-" logfile: to file! join "error-" [date ".log"] save logfile mold disarm error ] ] (this will log each error into its own file called error-date-time.log) and - more importantly - it should continue executing. B. It picks up values from all the scripts it generates via email That I don't understand. Where are these values coming from? Remember, REBOL does garbage collection, so I would assume - depending on how popreader.r is written - that old values are garbage collected whenever you rerun popreader.r, because popreader.r will reuse the same words it used previously. When the words are reused the old values become orphaned and are garbage collected. So you shouldn't be accumulating any garbage. But then again, I haven't seen popreader's source, so what do I know? In any event, it should be possible to write popreader.r in such a way that you don't accumulate stuff over several runs. Hope this helps, ;- Elan [ : - ) ]

[REBOL] Find speed Re:(2)
Hi,
regarding memoizing. There is a class of functions, that must use
some kind of memoizing to work at all, I think. The number of the
possibilities for parameters does not matter, you can store only
important results (depending on what you consider important - eg.
expensive or recent results...)
Because I used a non-real-life example for testing, here is
something more adequate for memoizing purposes:
Block/find time: 14.5 count: 7771
Block/bfind time: 5.875 count: 7771
Hash/find time: 28.5 count: 7771

Hi, Ladislav,
if you are interested only in an associative array,
then a properly implemented hash should beat the
hell out of even a binary search on large data.
I guess it depends somewhat on the quality of the
hash function and other aspects of the implementation.
So, if you can beat the Rebol hash, which is probably compiled
c-code, with your binary search written in interpreted Rebol,
then RT had better take a look at their Rebol hashes.
Would you like to share some test source code with us
so we can try to duplicate and analyze your results?
Thanks!
-galt
p.s. Does memo-ize only make sense when there are a limited
number of possibilities for the parameters? If the space of
possible
values is very large and requests could come in a sort of
random or rarely repeating way then the memo-ize trick wouldn't
do much good, would it?

Well, it all depends on HOW they will be updating the site and what is it on the site they will be updating? I've written a script which allows people to update a site of news headlines by sending an e-mail to an e-mail address. If you know WHICH content you want them to update, you can do the same. Here is my script: http://www.bebits.com/app/1226 The other way to do it is to set up a site with Web-based forms from which they can update content. The situation I have is that I'm going to do up a web-site for my sister's company. I want to be able to implement a consistent style for the site and yet have my sister or her staff do the updates. Since they are not familiar with Web pages (and I don't think they should have to be), I was looking for some sort of automated process.

[REBOL] An experiment with RTF Re:
Hi Brett, would you consider using AbiWord? It's a beautiful, open source, portable word processor (still in prelease, but it rocks). The advantage is that uses an XML based page description language that can easily be parsed using REBOL's XML parser and then converted into the appropriate HTML. you can download a copy at http://www.abisource.com Advantages: 1. AbiWord has a relatively small footprint (compared to MS Word). It loads much faster. 2. You can download the source and you could conceivably add a button that a) saves the current file, b) starts up REBOL and has REBOL parse the saved file, and c) posts the file to the Web site. 3. AbiWord is similar enough to MS Word that I would think that anyone who can use MS Word will be able to figure out AbiWord quite easily. 4. Big plus: You do not place your solution in the hands of a 3rd party. I.e. you control what your software does. With MS Word, if Microsoft decides to change something about MS Word, and you happen to rely on that feature, and your sister's company wants to use the new improved version of MS Word, they will have to keep two versions of MS Word around, which may cause confusion, take up alot of hard drive space, and conceivably occassionally crash the computer. I think we should adopt AbiWord as standard front end for text and XML oriented interactive solutions that include REBOL as a scripting component.

[REBOL] Find speed Re:(3)
Hi Ladislav,
your test function is responsible for the results you get, not the hash!
The critical code in the time-blk function is
start: now
loop :count :block
finish: now
When you test the hash function, your timing function (time-blk) loops over
the block:
[
random/seed 1
c: 0
blk: make hash! []
repeat i n [
d: random m
if not find blk d [
c: c + 1
insert blk d
]
]
] 0.05
This block includes the CREATION of the hash and INSERTING items into the
hash. Certainly creating a hash and inserting items into the hash is not
the same thing as searching in a hash and the time required to CREATE the
data structure and INSERT items into the data structure should not be part
of the value reported for the time required to SEARCH in the data structure.
Inserting an element into a hash is by nature of hashing algorithms far
more time consuming than inserting an element into a block. Hashes are
optimized for locating an element at the penalty of consuming more time for
insertion. To correctly identify the time it takes to locate an element in
a hash, you must separate the insertion of the element into the hash from
the time you calculate to retrieve the element in the hash.
If you separate insertion from the search in a hash, you must do the same
for the blocks as well. Only then will you be able to compare values that
reflect how long it takes to SEARCH in the different series types you are
testing!

Hi Tom, What version of libtermcap does your Linux box have installed? (Look in /lib) If you don't have a file or symlink named libtermcap.so.2, you can *probably* make a symlink with that name to whatever version of libtermcap you have installed. what about trying "ldd rebol" to see the dependencies? It helped me in problems identification with libc versioning ...

[REBOL] Changing relative paths to absolute ones.
Hello. I have been monitoring the progress of REBOL since its first release but only now I will start to use it to do something usefull. I created a simple script to read a web page and to send it to an email address (send user@host read http://www.server). The problem is that there are lots of relative references in this page (IMG SRC="/somedir/file.gif") and I need to change all of these references to an absolute path (IMG SRC="http://www.server/ somedir/file.gif"). I think the problem would be solved if I search for all =" and change it to ="http://www.server . How can I do that? Note that I didn't even understood the REBOL syntax yet. :) Thanks. -Bruno
[REBOL] Com port parameters. Setting How? Re:(2)
I found another (and smallest) serial to tcp/ip program at http://www.emtec.com My understanding is you cannot access the com port directly from Rebol. However, I used IPComserver a program by http://www.iox.co.za to essentially give the Com port a tcp/ip port. Then I could use Rebol with tcp/ip through IPComserver to talk to my device.

[REBOL] Previous version Re:
Quoting [EMAIL PROTECTED] ([EMAIL PROTECTED]): Hi, Has anyone got the previous version of Rebol/core for Linux libc6, I asked my ISP to install the new version on their servers, unfortunately the new version isn't working Then they have some other problems, Rebol/core for Linux libc6 works fine for me. It could be the old thing with mixing libc5 and libc6, though. they copied over the old version What kind of an administrator copies over old and working versions.

[REBOL] Netscape vs. Explorer ??? Re:
Hi Ralph, Is there any way you can avoid the comma? Some Options.. 1. Encode it, and see if MSIE and NN can still handle it. 2.
