AltME groups: search

effectivly true... if you have a connection and the world_name-server 
goes away you do not loose the connection you have.

If you had a pkt tracer check out the traffic going to 66.218.43.215 
port 5500

;Interesting every second the client send a request that looks like
cmd: live data:  [world-name binary64]
;and the server replies with this
cmd: lookup data: ok

In the case above the "client" is my private AltMe world server. 
So the traffic is being sent from my server to the nameserver every 
second. I guess is a way to keep the ownership of the free AltMe 
world names.

Thank you, and yes we did.  The error that happened today was fixed, 
and an additional check is now being made to prevent that from happening 
again in the future.


One thing I can clearly say is that each problem has been unique, 
and each time one happens (a severe failure) we stop everything and 
jump on it, and in addition to correcting the current problem, write 
code to prevent the same problem from happening in the future.


We have been down less than Live Journal, which has millions of people, 
and hundreds of servers for the same time period.  So we rock!

Modesty is a disease, and it wastes time, and truncates communication,

Yes, see windows group .. I tried it a couple of weeks ago.

Well, then.. you best be getting over to the Blog Chat group and 
get on Anton's case.. I see a quote there that's obviously out of

oy. Talk about a crappy duty. Sorry, Graham ;-)

If i  paid $.02 for every time someone felt the need to criticize 
my $.02 worth, I'd owe AT LEAST a $1.50 by now.

This job is reminding me more and more why "data is code is data" 
could be a good thing.

A compile stage for web apps is just not right, anyhow.

yay :-)

what's the best way of restarting a server application each night 
?  Use something like launch/quit .. between certain hours, but without 
setting some flag on the file system, how to ensure that it only 
happens once daily?

a:  "123.456.789"

find/any/with   a  "*.456.789" "123"

The /with refinement allows you to use alternatives to * and ? wildchars:

>> a: "123.456.789"
== "123.456.789"
>> find/with a "x.456.789" "xy"
== "3.456.789"
>> find/with a "y.456.789" "xy"
== "123.456.789"

In some cases I've done that Graham, I've also made a special "startup" 
EXE for a script that runs, waits a bit, the DOes the script, to 
give things a chance to shut down. I've also done it where the app 
was simple and I could just DO a module to refresh it. That gets 
trickier if you have a more complex app that maintains state and 
such.

My stuff has all been manually restarted, though sometimes remote, 
and not timed, but that shouldn't be an issue. Another thing you 
could do is put a shutdown timer in your script, and then have a 
CRON job run that starts a new instance.

I guess a cron job that signals my application to restart would be 
the best thing then

Some of them are natives, and some are mezzanine code.

That gives you a choice: use the natives for speed, or the mezzanines 
for convenience.

I was just gathering a good minimum set for another introductory 
article. I think I'll leave most of the iteration bits out for this 
stage.

Or just point out the basics.
9/10 I just use 'loop or 'foreach.
Other people probably have a different preferred subset.

hmm, that's a good thought. I'll keep the coverage small: 'while 
'loop 'foreach should cover most beginner needs
It might be a good idea to menation 'break as well

not sure what you are trying to do, but the following is a better 
natural form once you get your string stuff INTO Rebol ... because 
REBOL will see it as its own datatypes, rather than as strings. [193.194.70.123

Anyone know if there is a private group here for religous discussion

I guess you want an output that shows a text-list with the hostname 
joined to the port?

digit: charset [#"0" - #"9"]
letter: charset [#"a" - #"z" #"A" - #"Z"]
char:  charset ["/<>^/  :" #"a" - #"z" #"A" - #"Z"]

or is this supposed to be a 'trick' question that I am slow to catch?

I am not a Christian.


But, given that Easter always falls on a Sunday, there should not 
be an 'Easter Monday'.

Holiday 'in lieu' for Easter may be something that is technically 
correct.

Easter falls on the first sunday after a certain full moon,  if I 
recall

most likely the third fullmoon of the year  but there is a more complicated 
way of knowing ....

>> x: now/year
== 2005
>> x // 19
== 10
>> a: x // 19
== 10
>> b: x / 100
== 20.05
>> c: x // 100
== 5
>> d: b / 4
== 5.0125
>> e: b // 4
== 5.00000000000007E-2
>> f: (b + 8) / 24
== 1.16875
>> g: b - f + 1 / 3
== 6.62708333333333
>> h: 19 * a + b - d - g + 15 / 30
== 7.11368055555556
>> i: c / 4
== 1.25
>> k: c // 4
== 1
>> l: (32 + e + e + i + i - h - k) // 7
== 5.48631944444444
>> m: a + (11 * h) + (22 * l) / 451
== 0.463302691549642
>> month: h + l - (7 * m) + 114 / 31
== 3.9792542309404
>> day:  h + l - (7 * m) + 114 // 31
== 30.3568811591525

so according to that March 30 2005 should be easter (but it is not 
a sundy) prolly the 27th  then

easter?: func [ {given a year returns the date of easter.

I ahve a easier time maling the function than the library header

If you upload a script without a Library header, one should be inserted 
automatically.....You just need to update it to have the right values.


Several people have claimed that it should be possible to get 99% 
of the right values by analysing the script automatically. So far, 
no one has demonstrated a header-writer. Maybe you could write one 
first!?

Not as far as I can see.

For no explicable reason, not all scripts on the "old" library made 
it to the "new" one.

That was not a deliberate quality/triage choice -- just some somehow 
slipped the net.

here's the old rebol.org list, probably a few missed gems in there. 
http://web.archive.org/web/20021208011501/www.rebol.org/fl-list.html

Plus there were a load of unpublished scripts in the old REBOL.org......I'll 
just officially describe some of them as "weird".

From my perspective it's only been months, and even that is a little 
too long :-)

Where is the URL I can point folks to for learning about how to set 
up a Rebol3 account? I seem to have lost the bookmark for it.

Brian, I have already sent a link to your site to several people. 
 They like it (they are none Rebol users).

So to cut the discussion, I have added the Easter day function to 
the Library. It is the same as the TomC func a few lines up.

loop, repeat, for. I'm not covering iterating through a list yet.

Well, I take a brief glance at iterating through a list in the last 
part of the chapter.

But Rebol sound port is buggy.  At the moment I am working on a FMOD 
interface (www.fmod.org)

heh. the rebol-unit author said that he wasn't maintaining it and 
I could do whatever I wanted with it as if that were a *bad* thing 
:-D

That's good. I'll probably keep playing with this one a bit, partly 
for the learning experience as much as anything else.

Run is done by RebolTof, Belgium developper, who works for Belgium's 
army.
So RUn was develop and is used in real case.


He has also done RAPId (Rebol API Documentor), a JavaDoc like Document 
generator for Rebol
 https://sourceforge.net/projects/rapid/


For the english doc, contact him directly [christophe-:-coussement-:-mil-:-be]

Thanks for both of those links, DideC. I am very interested in taking 
a closer look at RAPId!

dumb question: is there a REBOL build with AGG available yet?

Are any plans being made to make a rebol build to take advantage 
of the AMD Athlon 64 FX CPU?

argh, I hate it when I can think of a million better ways to run 
the place I'm working. 

Especially since I know I'm wrong!

Is there a rebol script to download Open Financial Exchange data 
from a bank?

I'm not just a bad spelling, I'm just dyslexic, I'm not just high 
functioning autistic, I also have a primitive pattern buffer.

The embarrassing thing is that this is not the first time I've accidentally 
erased a part of my site. I still hadn't learned my lesson, I guess. 
:-)

no, it's only a half-dozen files, and I have the output. It's a minor 
matter to fix.

A benchmark comparison site for various languages.

Brian, from the language shootout FAQ : 
    Why don't you include REBOL™?
    REBOL™ is a commercial product.

A stat I use is based on Moore's Law....size (for same feature set) 
 makes REBOL a win every time.

aha, that is similar to Christopher Alexander's "Quality without 
a name" ("A Timeless Way of Building", much better IMO than "A Pattern 
Language")

a good architecture takes an open space and divides it into places 
where stress for the human is minimized.

heh. I think I've been referred to that title before by a Ruby person. 
Twice now. Okay, I'll go look at the library.

He started writing a book on "The Nature of Order" but not sure if 
ever completed...

All right, that's two books on hold at the library. I'm cheap. I 
read a book a couple times, then decide if I want to buy it :-)

In the other Rebol worlds we had a group of books

It has a drop directory for playlist updating

Just wanted to give everyone a piece of advice regarding spyware 
and how to really keep it from effecting you.  Permissions is the 
key word here.  Disable all access to prone registry keys and startup 
directories and other entry points.  Its extremely effective.

I might make a util some time for doing all this so that before you 
install software you can quickly undo the changes.

another tip : make everyone run as a limited user in XP

There are many Colin.  I would get more specific if I had more time. 
 But the browser keys for internet explorer in both and default users 
key as well as any established user keys.  Also a mus tis the RUN 
keys in the same.  Deny access for the proper group your account 
or others accounts on the machine are using.  There is also the shell 
key you would  want to protect also as many viruses like to alter 
the shell line.  Put permissions on autoexec.bat autoexec.nt  win.ini 
system.ini config.sys  and config.nt also.

hum, I need a dll built up from a mathlab project...

oh its, not my project, its the opposite, trying to find someone 
to convert a third party mathlab project into a easy to use stand-along 
rebol dll with only one .h file to translate...

its current a multi-file ordeal with some mathlab scripts ...

and cpp, + .h files all mixed up...  and a dll for some funcs...

I don't know... but mathlab has a compiler which is supposed to allow 
creationg of C object modules or dll files for easier integration 
outside of mathlab... (thats what it says on the web site anyways)

I once "translated a matlab script to Rebol and was amazed how Matlab 
computed square-root

anyway I doubt about the correctness of such a program

yet there lies a paper which has code along with it which allows 
us to select obects in an image merely by painting vague strokes 
on them...

and its coded in mathlab...

Can anyone give me a good tip for a free tape backup program that 
is able to backup workstations (windows) on a LAN via UNC names like 
\\my-system\c$

Bo has written such a utlity .. that also backs up to a ftp directory

I have a program I made myself also.

It would be nice for a rebolish way to interface to tape drives and 
dvd writers

Hi, does someone know a good development environment which can create 
DLLs and simplifies COM programming? I want to create some wrapper 
DLLs for Rebol that use COM objects. But I really don't want to hack 
through MBs of MS header files etc.

Hmm... my Pascal knowledge is a bit rusty ;-)) Thanks.

My son Josh wrote a tutorial on this.  I don't remember at the moment 
exactly where he put it, maybe on his web site, but I will find out. 
 A very simple, to the point how-to.

There's a Free clone of Delphi out there called Free Pascal with 
a GUI-alike called Lazarus, but I doubt its COM support is that good, 
and they can't do the GUI as well because the best features of Delphi's 
GUI are patented by Borland. I think Microsoft licenses those patents 
for Visual Studio.

Josh, thanks for the link. My problem isn't creating the DLL part 
but getting the COM part done in a simple way. Writing the wrapper 
for Rebol is done quite fast.

Do you mean that it has a bnf parser included?

Except that being a pure object environment, you have a lot of small 
methods that accept very specific messages, so you don't really create 
dialects, though you can take the first step and create a vocabulary. 
It just doesn't get used the same way. I'm not a real Smalltalker, 
only tinkered a bit a long time ago, so someone correct me if I'm 
wrong.

Yes. Any Rebol code can change the way the language functions:
>> copy: func [a] ["hijacked"]
>> b: copy "123456"
>> b
== "hijacked"


As dialects are implemented in Rebol they can change the way the 
langauge functions.

dialects are interpreters, which you can write in rebol. as interpreters, 
they can change everything. from rebol they inherit datatypes/syntax, 
which saves a lot work and makes things consistent. and the binding, 
which makes it easy to have variables in dialects and share them 
with rebol. the nice thing it, they keep their context. if you just 
pass strings and use regexp, you can do dialects in perl too, but 
the strings don't keep their context. which means sharing namespaces/locals 
with interpreters is less comfortable upto impossible.

I am working on a "REBOL powerpack". A set of libraries to help developers 
jump-start development. Check the REBOL powerpack group for details.

Funny question: What's a good iconic metaphor for "Save file"? Okay, 
we're used to have a floppy-disk-icon to click on, but do all people 
now-a-days remember what floppy disks were? I can't imagine a working 
successor, though. An USB-stick pixeled on a 16x16 pixel grid?  Not 
too easily recognised, I assume ... Any suggestions?
