AltME groups: search

so, I'm somewhat pessemistic about a community collaboration on such 
a project.


Pessimism implies something can fail�what can fail here?  Centralized 
information does not exist.  Building a site that centralizes information 
instantly accomplished the goal, as long as it can be updated by 
the very creation of information.  If it was nothing but an RSS transponder 
it would already accomplish something.


The trick to all of this is simply opening everything up.  Which 
brings up another great example, you blog, and your blogs have 0 
comments.  I blog (to a more private forum not computer related), 
I get anywhere between 20 and 100 comments.  But it is because I'm 
linked off a centralized feed.


People need to be invited in, given places to go, and know that things 
are happening.

what I want to do is feed date data and let the graph program automatically 
generate the x-axis labels.

Brian and Pekr, you can easily define where your foreign! value (garbage) 
would start, but you cannot define in a *general* way where it should 
end. You can only define that on specific cases and with specific 
rules. That's Gabriele's point. 


For example, let's see how an invalid input could be parsed using 
a theoretical foreign! type (represented below as quoted string for 
easier reading).

Test input string to parse: "123 abc 4c5.6"

Possible alternative outputs from a relaxed LOAD:

[123 abc "4c5.6"]
[123 abc 4 "c5.6"]
[123 abc 4 c5.6]
[123 abc 4 c 5.6]
[123 abc "4c" 5.6]
...

Question: which one is the correct output that LOAD should produce?

Answer: you can't know until you ask me what I wanted to express.


You cannot expect from LOAD to know how to handle invalid data (and 
to determine where it ends), the best thing LOAD can do is to stop 
on syntax error. If you have hints or rules on how should foreign 
be parsed, then write some parse rules and use string! parsing.


LOAD/else is a nice REP, but again it can only work on specific data. 
You cannot feed it with *any* data and expect it to work.

Sunanda - those a good points. So search the rebol web server log 
and see what the key words were that got hits from the SE. Start 
building pages that maximize those key words, have links back to 
your main Rebol sites and feed the SE with these links. Its an interative 
process that takes time and effort. At the moment all we see is time 
being spent.

Hey Riechart, we need a way to feed messages automatically into AltME 
 - to allow an email feed to reach it.

Reichart,
 

1. Are there plans to provide an RSS feed (or multiple feeds) trigger 
by AltMe world activity? 

I would like to be alerted to my RSS reader when updates are made. 

It is not so necessary for Rebol3 but I am proposing an Altme use 
where activity might start out less frequent. 


2. Is the AltME export capability that Rebol3 has for the public 
groups a general use feature of a SafeWorld?

So�.


We have already put RSS, iCal, and iFrame feeds (syndication) into 
Qtask.  If you post these in a Rebol project calendar (on Qtask), 
then you can create a feed from it, and post it publicly!  You can 
even post the entire JavaScript Calendar into the page of a public 
website (like Rebol.org, etc.)

Uae the rebol.org feed .. the rebol.net one is broken

now, how do I send a page feed to the printer ... ?

tried insert port #{0c} but the paper won't feed :(

If you can issue a DOS command (REBOL/Command or some betas with 
Call enabled), try this:
    echo ^l > prn
(That's a ctrl+L character, not a caret then L)
That should force a form feed

i would use grhams solution and feed what rebol sees back into the 
input-field. so user sees something is wrong.

;To make the following work with a USB printer, do the following:

; 1. share the printer, noting the name given to the shared printer.

; 2. from the command line type: net use lpt1 \\laturk-ws-2\EPSONSty 
/persistent:yes

; 3. put said command line in autoexec.nt so you don't have to type 
it each time.

printer: func [
    "Sends text to printer on //prn."
    [catch]
    Text [string!]    "The text to be printed."
    /Page    "Append Carriage Return (CR) and Page Feed."
    ][
    throw-on-error [
        secure [
            %//prn [allow write]
        ]
        write %//prn Text
        if Page [write/binary %//prn "^(0D)^(page)"]
        Text
   ]
]

It would be nice to have an RSS Feed for the "What's new " section 
on the Script Library home page.

Sunanda, Can it be a manually maintained xml file until it can be 
automated?  I am doing that for my internal blog until I add the 
automation code to blog. r (that I expect Carl already has on his 
version).  I have a trigger for when a blog article is added to use 
"editor ftp://...../rss.xml"to make whatever additions that I want 
to expose via RSS.  It's suboptimal but I don't have any complaints 
from the people that they have to visit the pages to see What's New. 
 And since they weren't visiting regularly to poll for What's New 
anyway, if the RSS feed it updated a few hours later it is still 
an improvement.

Check out the front page of REBOL.org:
-- it tells you the latest message on the ML: when and what.

-- the RSS feed tells you all the latest action, including new/updated 
threads on the ML.

or just make them an rss feed so that you can bring them anywhere?

I would welcome more open AltME design - it is a good app. But maybe 
on rebol.org we could list on-line rebol related worlds, and provide 
free accounts, and maybe later on we can come up with mechanism, 
how to feed some info into db .... to be searchable

No need for second guessing -- REBOL.org already has the "feed me 
a plain text" link -- use the Download script link for that.
That's simplicity......Isn't it!?

Carl knows the problem ... well at least I had the chance to talk 
to him once trhu a feed back... and also there was a ticket in the 
past ... i remember... but then

Think of iterated function as another way of "show". Only that this 
show is called multiple times on a real show. One time for each row. 
so you can feed different data (and offsets!). Looks like multiple 
faces, needs space for one.

I would have thought, that it was something about feeding a new event 
into the system with the face as a target. That is: creating a entirely 
new event and feed it into the event system.

For those that want to set up there own site, OK, but then what they 
should do is feed an RSS to the central site.

But in postscript, it ignores the line feed, carriage returns :(

You've already seen my psd2draw.r script .. I just feed the same 
block thru my ps dialect to get the postsrcript and write that to 
a file.

Thanks for the feed back, all is most welcome. I will try to avoid 
read/line if it is bad, is there a list of things I can't expect 
to load?  Should I convert them to some symbolic value & then convert 
them back again for the final output?

I don't yet understand why a block would be easier to parse than 
lines, by easier do you mean more efficient or easier to create the 
code?

The optional rules (inside parents) are to change the behavior based 
on lines read previously so I don't yet understand any concept that 
would let me avoid those. 

I need the code to be very simple (like me) so I can understand how 
it is operating. I know my implementation goes against the Rebol 
ethos of  small & efficient but perhaps in time I can understand 
enough to make it so & also start using relative expressions properly 
so it can be simple to understand.

I think, for the way Geomol is thinking, that his best approach would 
be to enforce his heirarchical structure on the writer, he might 
need to make his rigor as a pre-make-doc dialect that would feed 
to make-doc dialect.  Not hard to do, or he can bypass altogether. 
 Lots of room for experimentation, since the source is there.  Tremendous 
advances can be made by good experiments.

I don't think you can do that 100% within rebol, but Printfile seems 
to let you spool PS from a watched directory. Store a PDF or PS file 
in that specific directory and it will be printed. Printfile can't 
run as a service or in the background it seems.

It's easier under Linux where you can employ PDF2PS and just feed 
it to LPR, which will then print it.

is ^J the line feed ?

well, I was trying to say that I had not realized this was possible... 
and its quite cool... we can actually use that in some ways  ...


 make rules which make parse become an event handler for example ! 
  the moment you feed a string some value, parse will start treating 
 it...

I have a question on the above parse by Oldes on Feb 8th.  
If you feed in a [a b c d e f] you will get a-b-c-==false

How can you change the parse so that it will put a dash in between 
all characters, without defining each character?

this may bot be a well formed thought but ... the ability to directly 
feed a port into parse

If you don't feed it the VMware image, you must at least choose the 
VirtualBox installation option

Actually I'm playing with festival on linux  ;) REBOL festival Client 
 with visual interface to feed the festival software running in server 
mode only take 10 lines  I love REBOL :))). So now on linux I can 
make my Computer speech me  the Carl's blog content while I'm in 
the mean time reading the French forum new posts ;)

The core of the problem is that OSS people write their software, 
then they move on. After all, they cannot spend all their time on 
it, because they need to feed themselves.

it sucks because those with the vision can only do so much on their 
time.  although everyone is happy to say free things are great, free 
things aren't worth any $$ and thus, you get none to feed your children 
when you work on them.

The sad state is also that we have this strange and powerfull urge 
to feed... and working on software for free... is usually done by 
need, or Academia, cause they can.

If you call it .. so what?  You can't feed it parameters.

when I upload my script, I don't feed it with full path, just !#rebol 
-cs, if the interpreter is from the same directory ....

Sorry to feed. A more complete test script :

Not really, just emulate the immersiveness.  I dealt with 16 lines 
of 64 characters for so many years that my little utility (in menta-space) 
uses a 32 by 80 character screen but all the output is normal text 
(with those confounded carriage returns).  We used shadows blocks 
extensively and I got so used to the technical docs being single 
letter command away...Just pineing.  Aside from that, is there a 
way to feed the string  $1,000,000  into block parsing?

Some of the things people do are utterly ridiculous.  They compile 
assembly to DOS .COM files and claim the resulting hex bytes constitute 
program code because you can feed them into the console.  Other approaches 
obfuscate the code beyond belief to where you really can't make the 
slightest change to them--they are effectively not source, but the 
result of a bizarro compilation--often written using some kind of 
assistive tool or calculator.

I have to occassionally access websites that make heroic efforts 
only to work in IE. Banks mainly.

They sniff the user-agent  ID string....If you try faking that they 
feed you javascript that crashes other browsers.
Somehow, they think insisting on IE is safer.

Means I have to manually set their sites to the most restricted set 
of IE settings possible -- after all, why should I trust a bank that 
thinks that way?

Having REBOL formatted output is / can be a good idea: REBOL.org 
will supply its RSS that way if you ask it nicely:

http://www.rebol.org/cgi-bin/cgiwrap/rebol/rss-get-feed.r?format=rebol

But *automatically* supplying a different version to a bot than that 
you would show to a human is called cloaking and the search engines 
don't like it at all.

If they spot what you are doing, they may ban you from their indexes 
completely.

As I said, the RSS feed is explicitly intended to feed data to other 
programs for formatting, so it doesn't (perhaps can't) look nice.

All the info is available in human friendly ways elsewhere on the 
site, eg:

script library changes: http://www.rebol.org/cgi-bin/cgiwrap/rebol/script-index.r

Hi, I'm looking into Chris' emit-rss.r script, however, when I run

that we still are in the Keep it simple ability ;)

feed eatch other ;) no feed it other ;)

Would someone please give me an example of how to feed data from 
a sqlite db into a rebgui table?

rebol.org library already have tagging for the scripts.


Both in terms of levels ["Beginner" "Intermediate" "Advanced"] as 
well as the domain ["cgi" "gui"] etc...


Perhaps there is a way to feed the cookbook examples into rebol.org 
and let the Library be the holding place for future cookbook examples.


There are '3 major' rebol sites (those with rebol in the domain). 
And they are rebol.com, rebol.net, rebol.org.

It is not incredibly clear whether certain docs should be in .org 
or .net. 


Other suggestion to consider is how can we leverage off works done 
in various sites and avoid duplication. Why not let rebol.org be 
the host for cookbooks as well?


I would think new comers will prefer to find both cookbook examples 
and other contributed scripts all in one location. Rebol.org also 
lets you search the mailing list.

RebXML: I did some testing with rebxml, the documents I used can 
be found here:
 http://www.simplix.de/rebol/resources/xml/xmltests.zip

There is also a simple script that reads the XML docs in and writes 
them back.

Some problems I found:
- empty attributes, I have fixed this in the zip

- entities in content: all should be escaped, because they can be 
found there, otherwise a " gets "
- comments after last element missed
- comments before first element - missing line feed
- missing PIs in output


Another question: encoding - it seems that all output files will 
be written in iso-8859-1 ?

anyone here had issues with receiving Form feed characters in XML 
(which are illegal in XML 1.0) ?

as someone who tried to watch the proceedings of the last devcon, 
it was not so much the video feed that was of value but the slide 
content, audio and perhaps the role altme played in proviiding feedback/questions 
from those not present , perhaps a tool could be built to facilitate 
this process ?.

is there one (cannot feed more than one from here) brave soul connected 
from europe and with VLC or QT?

just over an hour and still no video feed ... at http://www.colellachiara.com/devcon05/live.html

Perhaps there isn't going to be a feed ..

this is like an apple keynote... where people debate whether there 
will be a live feed or not up to about 5 minutes before the show 
starts :-)

I recall last year it was Jaime and Gabriele that setup all the video 
equipment and the feed... maybe just not enough time.

Shame about no feed from Italy ...


Petr .... webcam in Rebol may be a bit ambitious .... we cant even 
get access to real time sound. !

I wish you had the feed,  it is a real shame this is so hard to make 
happen!

may thanks reichart for this feed !

Can anyone help answer this question --- received as a Feed back 
message on REBOL.org. Thanks!
=====
Does Rebol support cyrillic?
I can't see symbols in my language in this simple program:

view layout/size [button "Нажми" [alert "Привет!"]] 400x300

How come that Rebol doesn't support UTF-8? Or maybe there is another 
way to see Russian letters on buttons?..
3 days of googling...nothing...

 example: view layout/size [button "Нажми" [alert "Привет!"]] 
 400x300
=====

I could construct a block of functions, a block of parameters, and 
a data variable . and feed them to the first function, gradually 
removing them from the blocks and passing them in the callbacks?

Is there an easy way to suppress a carriage return and line feed 
when hitting the enter button?

For example:  I'd like to be able to do this:
Guess # 1:  XXX <enter> "  Nope, too high, guess lower"
Guess # 2: YYY <enter> "  Nope, too low, guess higher" ...

Can this be done with the ASK somehow?

if i want a generic sum, people feed [ 1 2.5 3 ], it would be faster 
in rebcode, so makes sense. with hand-typecheck it would be slower. 
I guess its to rare to worry about, but i would keep the option.

but main reason is, its easier to remember, set seti setd add addi 
addd would be first thoughts.

I want to be able to go to websites, feed data to forms and fill 
them out and then grab the results .. where the forms are generated 
dynamically in javascript

Maybe something for Rebol as well:


dsandler writes "Researchers at Rice University have just released 
version 0.7 

of FeedTree, a peer-to-peer system for distributing Web feeds faster. 
Instead of 

polling feeds independently, FeedTree users cooperate to share news 
updates 

using multicast in Pastry, a scalable p2p overlay network. FeedTree 
reduces the 

update delay for existing RSS and Atom feeds to a few minutes without 
putting 

extra stress on the webserver (anyone who's ever been temporarily 
banned by 

Slashdot's RSS feed knows this is a real concern). Feed publishers 
can also 

choose to push digitally signed updates for immediate, tamper-proof 
delivery to 

subscribers. The client software (download) runs on Linux, OS X, 
and Windows, 
and works with any desktop feed reader." 
 
http://rss.slashdot.org/Slashdot/slashdot?m=3816

I guess one problem with a multicast tree is that if you're disseminating 
your RSS feed this way, you may not know how many subscribers there 
are.

just need more indians ... but not enough food to feed them I guess.

How to use Adobe PostScript language files properly.: http://www-cdf.fnal.gov/offline/PostScript/AdobePS.html

you also find a link to:)
PostScript Sins: http://www.byte.com/art/9508/sec13/art3.htm
Gripes: http://www.cs.wisc.edu/~ghost/doc/gripes.htm

There is a bug with printing multiple pages on certain HP printers. 
After the first page, some char is missing, that causes it to wait 
until you press the Online button or page feed button. I really would 
like that to be fixed. The work-around is to print to a file and 
have it printed using Printfile under Windows.

so for the other bug: I mentioned earlier that some printers I tried 
it on directly, will cause the printer to pause after the first page 
is printed. Then I need to press paper feed or reset the printer 
to get the rest out. Using Printfile for Windows solves that, but 
that program is really old and I don't want to rely on it in the 
future if my project is moved to Linux clients. I suspect there is 
just one char missing at the end of the PS file, but I don't truly 
know what causes it.

what I do to cause the error is make a ps file with postscript.r 
and then feed it directly to the printer. In windows I print directly 
to LPT1: to produce it. Under Linux I print it via LPR.

I've also seen a Laserjet 4500 lock completely up, when you feed 
it a specific postscript or PDF file.

I call gswin32c.exe and feed it parameters to use the win32pr driver, 
which sends a bitmap to the printer given as a parameter in the same 
call.

from Andrew Martin

Printer: func [Text [string!] /Page] [
    secure [
        %//prn [allow write]
    ]
    write %//prn Text
    ; Append Carriage Return (CR) and Page Feed.
    if Page [write/binary %//prn "^(0D)^(page)"]
    Text
]

ghostscript can generate pcl from postscript ... and then you can 
feed it to the driver

you feed a postscript layout through a parser, which fills in dynamic 
values and then it's run through postscript.r and then it's fed through 
system-print to the appropriate printing method.

just thought I'd share this list I built while coaching someone in 
using liquid last night...

SANITY PRESERVING KNOWLEDGE WHEN USING LIQUID:
--------------------------------------------


#1:  liquid isn't a bully  - liquid shares its state, but asks for 
data (pulls, observes, etc) from its subordinates ("parents"), not 
the other way around (it doesn' push or force feed, like a highly 
inneficient signal messaging engine).


#2:  liquid is lazy by default - unless a plug or one of its observers 
 ("children") is stainless, nothing will process automatically (thus, 
faces usually are set to stainless, so that they refresh automatically).

#3:  liquid has several computing modes in a single base class.  
  * linking is for once sided dependencies
  * piping is for inter-dependencies or synchronisation
  * containment is for data storage
  * linked-containment is for processed data storage   


#4:  liquid mutates - plugs automatically change computing modes 
when you call some methods like linking, piping and filling.  depending 
on the order of these operations, a plug may "stick" to its previous 
computing mode.  e.g. a piped node remains piped, even you attempt 
to link it to something.


#5:  liquid is alive - remember that as you are setting up a liquid 
network, your plugs will start receiving messages as you are building 
up the tree, meaning that the process() (and other) functions might 
be triggered before every expected connections are done. always verify 
the integrity of the data before starting the process.  (i just got 
stumped by this one again, 5 minutes ago).


#6:  liquid is a collection of droplets - each plug should do one 
thing or manage one step of a process.  the more you break up the 
network, the better you will be at making it stable, reusable, flexible, 
and fast.


#7:  liquid is highly memory efficient - !plug uses shared classes. 
 so all the liquid operations are in a sub-object called a valve. 
 Thus, when you call internal functions, remember they are within 
the valve, and you must supply the plug as its first argument.  my-plug/valve/stats 
my-plug


#8:  liquid is volubile - its slim-based verbose & indented console 
printing engine (vprint) is YOUR BEST FRIEND.  use it profusely, 
to understand the chain of events and what the hell is going on.

This is not really about Cheyenne .. but what is the better approach. 
 Using RSP to completely build your page and display it from your 
datasources, or to dynamically construct the page with javascript 
and then feed the data in Ajax like ?

At this time, and I far as I know, there should be live video feed 
of the sessions available on the Net.

Th URL will probably be disclosed on the Devcon Website the thursday 
morning. And of course, on Altme.

I guess there will be also video recording, but can't say for sure.

For those who can't come to Paris, the Video feed should be there 
:
http://www.sahores-conseil.com/?q=node/2

Video feed quality is excellent

refresh if the feed freezes

Is the link to teh video feed ON the website?  As in here somewhere? 
 http://devcon2007.rebdocproj.org/index.html

Anton, is your feed choppy? Sound drop-outs every 10 seconds or so?

Thanks to all who made the feed available!

Carl starts talking and the feed stopped!

The quality of the feed from France is very nice.

DevCon is over. But it was a QuickTime feed.

If you skim the transcript of the Altme group during DevCon2007, 
you can see the frustrations cuuased by the narrow channel between 
the meeting room and the rest of the world.

I think partially because the live feed was not a top priority for 
the organisers

One idea: If 50 people paid USD15 to be Internet Participants at 
 DevCon2008 that could fund a much better channel for them

We need a simple system to pass the video feed around, we think we 
found a service that works well...we need to talk to Mark (at Qtask) 
about what he finally liked best.

I would like to see a presentation system with concurrent audio feed 
from the presenter.
