AltME groups: search

About disreb: Sorry to be unclear originally. At the moment, it's 
R2 only (I'm currently sticking with the latest version of R2 because 
I understand that it has a more stable GUI), however I am very willing 
to incorporate changes for R3. I'm not yet sure what the best fashion 
of collaboration with the Google code site is, but hopefully I'll 
have some time to investigate tomorrow. Sorry for the late reply, 
but I have imperfect access to AltMe (it's firewalled at work and 
I forgot my password (ha!) so I don't have it working on the computer 
I'm programming disreb with). @Oldes, I hope you find it useful should 
you chance to use it! Thanks!

I often see an unchanging "internet busy" message when the computer 
awakes from sleep.

I need to click on the world name, as if I were change worlds, to 
break AltME's trance.

I want to put a second world on my computer / world server and in 
the past I spent a fair bit of time resetting worlds due to them 
becoming unreachable.

Tomc, wise.


I use Qtask since I know the notes will be there, or Qtask's Scratchpad.

Every time a computer crashes, or my celll phone resets, I'm SOOOOOOOOOOO 
happy.

AltME broken for me....


Background: this morning my Windows computer froze and I had to cycle 
the power on it. (AltME was running, but nothing to suggest that 
AltME was the cause of the problem).


After a reboot, AltME would not start -- complained there was a file 
it could not read.


No worries....I deleted the entire REBOL3 folder, and restarted AltME.


After it had downloaded 40+ meg of messages, all should have been 
back to normal. But the resync process got itself stuck, continually 
resyncing the SQLite group.


I have since tried downloading the whole world again; and I have 
uninstalled AltME completely and started again from scratch. Same 
problem.


Now, if I restart AltME, it looks okay at first. But, if I click 
into the SQLite group (or if someone posts a message to that group) 
the endless resync starts up again.


I am not seeing the problem on a different machine where I have not 
reinstalled AltME.

This is like the opposite of the ancient resync bug :)

***


I suspect the SQLite folder is somehow corrupt on the server; but 
the corruption only triggers trouble on a fresh install.....If so, 
we will all see it eventually :(

Can someone copy this to whoever maintains AltME? Thanks!

I'd just use encloak with some random text. If you think it's easy 
enough to get a system specific key, you might do that, but I don't 
know if users will be happy to find out that their passwords don't 
work anymore when they upgrade their PC or move to another computer.

its a choice I make.  and I know every single piece of data on my 
computer is vulnerable.

Even though I'm able to send e-mails from my home computer via rebol 
console using my host's SMTP Relay?

Back in time digression...


I have often noticed that it is unemployed as a method for complex 
testings.

In general it's faster and more easily readable than a serie of nested 
if / else.

But to do such, the programmer must know how testings can be complemented 
and other simplification technics.

The novice programmers (whatever the language) often find it difficult 
to do it correctly.

This is probably a gap in computer education. We don't learn anymore 
the basics of Boolean algebra.

At least for me it is an important criterion to determine the general 
level of someone in computer sciences. 
If I see too many nested if / else in a program.
I think the personn lacks of solid foundations in programming.

For instance, in R3 (can't check R2 right now on this computer) comparison 
is allowed to unset! and error! values can be done with operators 
if the unset/error value is on the left side of the operator, but 
not on the right. This is because operators redirect to actions, 
and action functions are different depending on their first argument 
(single-dispatch). The comparison actions for unset! and error! can 
compare to other values, but the comparson actions of other types 
don't support comparing to error/unset. The action! function that 
calls the action has a typespec for its first argument that doesn't 
allow error/unset, but the op! redirects to the internal action, 
not the action! function, and it works because it uses a DO trick 
instead of a standard function call.

why that ? the monitor run on the same computer than the serices 
no ?

No, the monitor may not be running on the same computer

Great, now I have AltME freezes and a cat that is jealous of my computer 
- double whammy to my typing.

1 is syntax for the "integer!" type, no semantics involved. The whole 
point of _data_ is that it has no semantics but a syntactic structure. 
That may not be REBOL's standard terms, but computer science instead.

I've a notion to build a business rules parser in Rebol. But as a 
self-taught hacker with no background in computer science, I'd welcome 
any advice on flattening the learning curve. The docs cover the low 
level parsing details well enough, but I'm looking for enlightenment 
on the higher level issues involved in designing a little domain 
level language. Given that Carl is pushing Dialects as the Big Idea 
in Rebol, it's surprisingly difficult to find much on the topic in 
the Rebol community. Or am I missing something? I'd welcome any Rebol 
specific or generic resources to help me get up to speed on the whole 
DSL thing...

I've got a radio frequency interference problem with my computer. 
When it's on, my mum's radio a few feet away behind a wall has an 
unacceptable level of noise added.

Does anyone have any suggestions for diagnosing / reducing the interference 
?

seriously, if you mean that you see funny stuff on the display, and 
you're using an analog connection to the monitor, try switching to 
DVI or HDMI (if that's one of the connectors on the computer). Just 
using an RGB to DVI convertor will might not do it since you still 
have part of the connection prone to interference

sorry, just re-read what you said - is the interference on the radio 
constant, or can you correlate it to activity on the computer (e.g. 
moving the mouse, hard disk activity, etc)?

line the computer case with it - or is it a laptop?

A possible complicating factor is that the shared wall between the 
radio and my computer has a power outlet on it, and an ethernet cable 
goes from my computer into it and down under the house, so those 
two things are both pretty close to the radio.
But I'll try lining my computer case first.
Thanks for the suggestions.

on my computer your annimation is lighting fast ... (maybe too fast) 
it's a very lively lizar lol

I found the Computer Language Benchmark Game a few weeks ago. Could 
be interesting to make REBOL and ORCA versions of those benchmarks.

Wikipedia: Constructor (computer science), a special method used 
in object oriented programming which puts the object's members into 
a valid state.

Another drawabck, if an existing user launch the chat from another 
one place (another directory, disk, or computer), the all the database 
is loaded again in local

This mean, there is as many different possible decimals between 0.0 
and 1.5 as between 1.5 and the highest possible 64-bit decimal, when 
talking floating points in a computer using the 64-bit IEEE 754 standard.

4 levels of equivalence, wow! Is that a record in computer languages? 
;-)

With your #[{ ... }]# suggestion, I think it looks pretty good, and 
could be extended with specification of an end delimiter. With so 
many computer languages of all different syntaxes, having a way to 
specify the delimiter allows it to flex to any situation. 
We could add a second string to the block, eg.
The end delimiter is END:
	#[{END} {... END}]#
or a simple newline char:
	#[{^/} {... ^/}]#
or a secure hash:
	#[{92838929838} {...92838929838}]#

The %rebol.r file is only meant to be used by the person who installs 
REBOL, for the purposes of adding custom stuff that is specific to 
a particular computer. Loading standard libraries will be handled 
by the module system instead. This is the same reason why we are 
planning to replace %user.r with a preferences file.

Every single broad decisision in R3 has been an enabling one for 
REBOL at large (both platform and language).   


Unfortunately, some things still require the core to be improved 
a bit, but we are nearing a point where REBOL will be able to fly 
on its own wings.   Just look at my attempt to get OpenGL to work 
with R3... it took me  10 hours of work from downloading the extension-enabled 
R3 version, downloading MS compiler, scrubbing the net for OpenGL 
reference material, libs, examples... and integrating all of this. 
 I've never coded OpenGL directly before... 


now imagine 100 of us doing this... that is what I see in REBOL's 
future within 2 years.  You will have things like trolltech QT bindings 
appearing, REBOL libs for any precise API out there... finally REBOL 
will be able to evolve with the rest of the world, and hopefully, 
impact its philosophy on the Computer Science more obviously...

if more people could actually USE REBOL daily, we'd see more of the 
philosophy of REBOL trickling into the industry.   People forget 
that REBOL is born out of a different perspective on computer science.

pekr yeah but when you computer is already filled with HTTP request 
adding more "SQL requests" slow downs your HTTP or at least that's 
the way i see it and that maybe too why all the database builders 
created another entry point called odbc

COLLECT is a quick programming function. It will get optimized out 
of mezz/library code, but will save time for programmers when their 
time is more important than the computer's, which is pretty often.

And we need platform-specific data too. It doesn't make sense to 
compare Windows and OSX, but it does make sense to compare R2 and 
R3 with each other on the same computer and OS. For that matter, 
there may be OSX version issues too.

Cyphre, onmy computer  with your mandelbrot-int.r script i get :

rebol 2 VM 2.7.6.31 : 0:00:03.904
rebol 3 (2.100.95a): REBOL Elapsed 0:00:04.354   


my computer in intel core i5  750 , 4Go DDR3 1333MHz Gygabyte P55UD3 
 

so maybe you should upgrade  ( and i'm sur where i lost most of the 
time where in the consol exists)

(oh and i had a 3D game running on the computer at same time...)

yeah but i like the  benchmarks based on deprecated harware ... as 
you could see  on a today's computer (and not even to top mark one) 
 the gap betwin R2 and R3 isn't so wide as stated by cyphre...

actually for example on windows 7 some HD video flash players are 
making  the explorer aero stack to hang and crash  so the desktop 
crash and i just have to reboot to use the computer again

I was quite surprised to see that Gmail and others accepted emails 
sent directly from a MTA on home computer...(I thought that I would 
need to make all testing from remote servers).

could there be any problem with running two cheyennes on different 
http ports on same computer ?

Working fine now. Seems very stable. Can only get a websocket connection 
on localhost, no connection from another computer on the same subnet.

Any problem in computer science can be solved by adding another indirection.

Has anyone ever seen the "Call" word not work? I've been trying to 
simply call %/c/rebol/view.exe and it shows up in task manager but 
I never see the application. It's not just that particular app either. 
The funny thing is I was successful doing that at my work computer.

It's been broken for so long, I no longer have the computer where 
I originally wrote it back in 2000 and posted it to the mailing list. 
It's still in my head though, so I'll collect it by Tuesday evening 
and start working. In brief:

- I don't know about installation on platforms other than Windows. 
Someone else will have to chime in here. Too ambitious for 2.7.7.

- Windows 2000+ support is still broken. Multi-user support is broken 
(same thing, really).

- Folder usage was mostly fixed in 2.6.3, but the registry is still 
misused. Registry migration will be needed.

- Non-admin installation should be possible, including user-specific 
file associations.

- Installation was broken altogether in the 2.7.x series - it doesn't 
work at all, not even to 2.6.3 levels.

- No-install usage of View needs better support. This means UI support 
too, if need be. VIew should be able to be a portable app.

Keep in mind that portable app usage of directories is completely 
different than installed usage, and needs to be.

2.7.7 kakks on an Atom chip single board computer running an embedded 
Ubuntu.   From desktop -> REBOL Demos

Seg Fault.   Should I care? (meaning, is Atom even on the expected 
to worky thingy)  I doubt the company will let me use any /View technology, 
but it would be nice to have for personal one-offs.   Some of it 
works, most of i

t kakks.   Always just the Get Smart  "missed it ... by that much" 
  :)

I found that OpenSolaris is awfully slow even when compared to slow 
Linux distributions like Ubuntu but that may be just my computer 
since OpenSolaris doesn't support that much hardware. Booting it 
took 10 minutes already but the whole system felt very sluggish. 
Some of the features it has are really nice though. The ZFS video 
where some guy used a big hammer to destroy running harddrives to 
show off ZFS handling it without any problems was cool :) What I 
would like to see Rebol run on is Haiku, especially since you develop 
native apps for it with C++ which usually is quite horrible although 
I have to say that the BeOS api makes C++ programming quite a bit 
less horrible.

And my major priorities that have been keeping me away from my computer 
for the last few months are near their end.

ICarii, as mentioned, I made a floodfill in my paint program. You 
can try it with:

do http://www.fys.ku.dk/~niclasen/rebol/canvas099.r
(Works best under Windows.)


On a modern computer, it fill with about the same speed in REBOL 
as DPaint did on an A500 computer 20+ years ago. I also made a rebcode 
version, which fills the entire screen almost instantly. That version 
isn't out there.

That is platform-and-computer-specific. And the user files will be 
in a different place for each user - that's the whole point of them. 
Is it really so hard to put files in the standard user directories?

The only weirdness in Vista/7 comes from the need to support roaming 
profiles. Windows is built around multi-user, multi-computer use 
over a whole enterprise. It took them a while, but they are finally 
starting to get it right in Vista/7. The only sucky things come from 
having to run apps that don't play by the 10+-year-old rules. So, 
would you prefer that those workarounds be gone and not be able to 
run AltME on Vista/7?

Works for me on XP (normally I would have 7 but that computer needs 
rebuilding). Right-click menu, ^V and read clipboard:// .

Nice, a tool that prevents you from using your computer, unless you 
tell them that you really want to

How come? Computer is started. User may start a program on Monday 
that needs to load cURL extension. May decide to start a program 
on Tuesday that needs to load 0MQ extension

I tell you what is so surprising about the results:


Since the result is the loop body execution time, it looks, that 
the loop body in Peter's computer works ten times faster. Gabriele, 
Davide, and Peter, could you please post here your result of the 
following expression?:

>> time-block [now/precise] 0,05
== 2.3651123046875E-6


 it looks that your processor works faster, Peter: your result is 
 the loop body execution time, which is about ten times shorter, than 
 the loop body execution time Ga

gemol if you want i can sell you minutes of use of on my computer 
:P

To carl concerning the timing problems noticed on my computer i got 
those result (windows seven; CPU core i 5 750, DRR3 1333 Mhz; R3 
a 97)

>> dt [loop 10 [wait 0.0001]]
== 0:00:00.000016

>> dt [loop 100 [wait 0.0001]]
== 0:00:00.000084

>> dt [loop 1000 [wait 0.0001]]
== 0:00:00.000783

>> dt [loop 10000 [wait 0.0001]]
== 0:00:00.007763


As you can see on my coputer my timings are lower than expected so 
sthis issue is related to CPU horse power.

Basically, if all your apps support this then it will be safe to 
turn on Automatic Updates and let your computer reboot itself if 
necessary, at least on Windows 7 (and maybe Vista).

Hosting Webkit wouldn't help here: The whole point to HTML5 etc. 
acceptance is that people don't have to install another program - 
they can just use their existing web browser. Hosting Webkit would 
only help us if we want to display existing web browser code; it 
wouldn't be necessary for generating code to run in Webkit, because 
the copy of Webkit that people would be displaying your GUI in would 
usually be a separate program, often on a separate computer. And 
HTML/JS/CSS is just text - we can generate text already.

yes, you can have several unrelated sets, just like you have unrelated 
apps or files on your current computer  :-)

Ok, except that the power of REBOL was that it can run under 40 different 
OS !

Nowadays, it runs good for R2/View under Windows and MacOS... Linux 
lots of problems because there's so many version of Linux...

And for R3/GUI we have Windows version... and when Windows 8 will 
be released... not sure it will work.

Community has falling down and it is hard with no open source to 
attrack new developpers... I know host-kit is hybrid open source 
model...

Real question in 2011 is : port language on JVM because every computer 
and device (except iPhone) has a JVM in order to reach the mass market.

Make it popular and then we can found money, people to work on small 
VM that make the power of Power.

Nicolas, those 40 different OSes weren't really 40 different OSes, 
they were mostly different builds for at most a dozen different OS 
variants. Most of those OS variants are now no longer developed, 
or have changed so significantly that they are essentially different 
OSes now. The platforms that RT is actively supporting now for R3 
covers the vast majority of the current market, more than would be 
expected for an alpha product, and the host kit allows you to port 
it to the most obscure OS you want, as long as it can work on the 
scale that REBOL works at (not your microwave).


every computer and device (except iPhone) has a JVM in order to reach 
the mass market

 - Of the most popular smartphone platforms, only RIM and Symbian 
 (sometimes) have a JVM; iPhone, Android, WP7, and WebOS don't.

After looking in dictionary on my computer, I'll say contents (plural) 
is more correct english.

The plural form:

the things that are held or included in something : he unscrewed 
the top of the flask and drank the contents | he picked up the correspondence 
and scanned the contents.
The singular:

the amount of a particular constituent occurring in a substance : 
milk with a low-fat content.

I do remember how QNX Photon used such a trick to share screen content. 
You defined X*Y area of the screen (imagine empty translucent face) 
and all events got via that "filter", so that you know what to send 
to target computer, and then the event was propagated to cause an 
action (at least that is how I understood it back then)

pekr,  there are things in Computer science which just are.   Just 
like there are things in maths, which just have to be accepted. 


R3 isn't inventing much of anything here, its actually much closer 
to normal boolean algebra than R2 ever was... FINALLY.   


in binary algebra, normally, things are right padded when sizes don't 
match... that's just how the maths behind it where defined long ago.


binary manipulation is an advanced topic, and you can't assume anything.

Last 3 or 4 months. I've been averaging about 1 day a week in front 
of a computer. I spend more time in my car.

INCLUDE has the drawback to be already used for other purposes in 
computer languages (like preprocessor).
We simply could peek a synonym, they are many.

COMPRISE, CONSIST, CONTAIN, HOLD, CONTAIN, BEAR, CARRY, INTEGRATE.

maybe i wasn't clear. Sorry i readed my post and some things appears 
not to be clear anough... 


1) Rebol runtime environement already exists that's the VM you install 
on your computer when you want to run scripts 

But a) it's not called a runtime environement  b) it's need disappears 
when you use REBO/SDK to "hide" your industrial secrets or when you 
don't want on purpose the client to install or know that  it's rebol 
behind.


2) by speudo compiling (byte code compilation) you allow people that 
need it to be a step closer to the hardware but keeping the portability 
effect so a rebol VM in my opinion should be able to  run both  a 
speudo binary file or a text script rebol file. Of course  like in 
java people would feel the need to share their software with embeded 
 Rebol Runtime Environement.


3) Having a runtime environement is the best modular way ...  core 
will be the base then you have View and lot of othe modules that 
wil clip to rebol. for example if i  put  import  "oracle" at the 
begining of my script then rebol runtime environement knows that 
he need the oracle package and goes to rebol.com to retrieve it and 
install it to the proper rebol runtime place in order for the vm 
to find it. Something close to what apt-get is to debian. REbol Environement 
doesn't comes with the whole thing but if the script tells it he 
can expend it selves in the fastest way. Well this runtime organisaton 
in  fact already exists but it's not pushed to it's extend, you know 
the point where the good idea become the best idea. the rebol/view 
2 implies a /desktop which implies a local scrit library (like a 
cache) to store the rebol script see the idea is there but once again 
it's not pushed to it's limits. Only rebgui used this system to store 
an extension to rebol.


4) by being closer to what people extend as an output you make them 
interessted in your input . To be more explicite by giving to peope 
what they are used to get in the end of their creation process then 
you allow them to be confident in your solution and to be more interressted 
on the way you propose to build your software.


5) i took java and .net as main example but if you look closely this 
is an expending tendency. For example Adobe Flash do that.


6) the other interrest in the compiled way is to merge the source 
code and the related resourcies at the same place (1.exe  file for 
example) and then forbiding the people to change their contents ... 
and this leaded then to the skining my application modo. Wich is 
just the we don't merge in the resulting binary the resourcies . 
In rebol we can already easyly build a script merger with data to 
output a .r file containing both but then people can still extract 
the ressourcies and change them etc...

one trivial but important question: 


OK rebol is a programing language that get most of its interest when 
used in the internet area.

So for example i use my brand new software made in rebol  it connects 
to internet and check for version update.

Updating a software from the software itself is a common feature 
now in day.


But with rebol how do we do that mechanics ? ok i can log to the 
webserver where are stored the release i can do a CRC comparasoin 
betwin 

my software and the  one on the distant server repository. So i get 
to know if the repository is different from the version installed 
on my computer.

Once my local copy is aware the distant repository evolved i can 
download the new copy.

And that's where the poblems appears ... I can't make the new version 
downloaded from the server to be subtituated like all the other software 

made in c, C++ etc... does. What i mean is i can do 97% of the update 
from the webtask but the automatic stop the current app and launch 
the new version is 
not possible...


if you want to better understand what i mean think about your firefox 
update for example

 at your firefox start it performs a version check then download the 
 new version
then close the current running firefox and launch the new one.

Does rebol 3 will introduce that kind of mecanics ?

and since rebol script are  most of the time very tiny in size  i 
don't see the interest of having an updated scheme looking like what 
is done on the other laguages. I htink it should be a cool thing 
to be able somehow to substitute anytime the file on my computer 
and then  autoreload it in memory without having to restart the application 
and if i could trash out  from memory of the VM the previous script 
that wuld be even nicer ....

but yes brianh you got the point when you relay on hardware then 
you have to choose what technology you support i know rebol main 
target is to be hardware / OS / driver abstracted .. but then you 
have a toy language anyone laught about that  can't bring anyway 
the same thing on every OS computer a part some very basic features 
like networking, encryption etc...

well problem is when you have several chips then you have to design 
alot of bus wich enhance alot the price of the computer imagine those 
computer have over a hundred or a thousand processor

and that's not even using the grace of my new hardware   i use that 
rebol script on my desktop computer or on netbook the results will 
be the same even if my desktop is hella goliath and my netbook is 
hella the small thing ... So people will say hey that's fantastic 
same animation run anywhere with same results (much or less ) but 
i would say  ... hum no

A little note about FUNCT vs. FUNCTOR: The word "functor" has a specific 
meaning in computer science, and that meaning is *not* what FUNCT 
does. There is no standard CS term for what FUNCT does, nor is there 
a standard English term. Any word we use would therefore have to 
be made up. FUNCT is not a bad made-up word: it's short, which is 
good for a function that will be used often in user code, and it 
starts with the same letters as FUNC and FUNCTION without being either 
one of those words.

I think, Carl deside these thing by trying to figure out, what makes 
most sense for a new one to programming. Or trying to make a more 
humane less computer technical language.

R3 doesn't have anything like R2's system/user. For all we know symbols 
could be garbage collected. In 32biit R3 though, afaik you will not 
reach the total number of possible words until you have already hit 
the limits of the memory address space first. Does someone have a 
computer with enough RAM to test this? I only have 4 GB.

And what about purchasing a faster computer ? 

(I'm in a deep shit right know, I don't understand what he's talking 
about)

From HELP MOD: "Compute a nonnegative remainder of A divided by B."
MOD can produce negative results as seen above.

From HELP MODULO: "Wrapper for MOD that handles errors like REMAINDER."

So REMAINDER must give wrong result in some cases. What does REMAINDER 
say:

From HELP REMAINDER: "Returns the remainder of first value divided 
by second."

That's what I expect a modulo operation to do. A modern definition 
is given by Knuth in "The Art of Computer Programming" using floored 
division, and this seems to be also the definition, Wolfram Alpha 
use. So I would say, REMAINDER give the correct answer in the second 
case, but not in the first.


As I see it, REBOL have 3 modulo functions, and none of them operate 
as expected, if Knuth's definition is used.

Considering the fact, that any REBOL code is loaded first (in the 
computer, but your brain should follow a similar procedure when reading 
it), i.e. handled as the "Data exchange dialect"/"Load dialect" (pick 
the one you prefer) before being (eventually, but not necessarily) 
submitted to any other interpreting function (like DO, etc.), the 
specially escaped format is useful, since it increases the expressivity 
of the "Data exchange dialect"/"Load dialect" (pick your preferred 
one).

I dont need to be too accurate just +- 5 seconds....


my server's time seems to be drifting. I've seen this before on an 
another computer...does a bad battery affect the time even if the 
power remains on?

GrahamC, thank you for passing this around.  I did get part way to 
a solution, as noted on your site.  Strange as it may seem, I am 
able to get to the network drives if I run a copy of REBOL that I 
download and leave with the name it came with, namely rebol-view-278-3-1. 
 The copy of REBOL that was giving me trouble was the same rebol-view-278-3-1, 
but I had renamed it to rebview to make a desktop shortcut work. 
 I had the name "rebview" in the shortcut so that I would not have 
to change the shortcut if I ever got an upgraded version of REBOL 
with a different name, like maybe rebol-view-279.  So my first problem 
with WIndows 7, REBOL, and network drives seems fixed.  


I still am not to a full solution to my Windows 7 issues.  I have 
some REBOL scripts that use the "call" command to run powershell. 
 Powershell then runs a powershell script to extract stuff from an 
EXCEL spreadsheet, which then is manipulated by the REBOL script. 
 Actually it's a bit messier.  I run a REBOL program launcher on 
the C drive which runs a REBOL script on a network drive.  The script 
on the network drive calls powershell with parameters to make powershell 
run a powershell script.  The powershell script extracts EXCEL data, 
and the calling REBOL script then makes a report of the extracted 
data.  


When I try to do this, the result from powershell is that I am not 
allowed to run scripts on that computer.  I am aware of this feature 
of powershell, and I have done what has worked for Windows XP (set-executionpolicy 
remotesigned).  I can run powershell directly, and execute scripts 
located on a network drive.  When a REBOL script that worked on XP 
calls powershell on WIndows 7, it won't go.  I am not expecting any 
help with this last issue at this time because the "call" does work 
in some cases (call/shell "notepad") (call/console/show "powershell"), 
so I still have several things to try, and if none work I am plotting 
a work-around.

Had the chance to read Git for Computer Scientists.

Any system that has a "rebase" cannot be all bad. ;)

Ah, I was going to lie down and watch TV on my computer in the other 
room :)

I would like to see some support for automatic logging of events.


Rebol currently has two "hooks" to allow "Front-end" code to execute 
automatically in the REBOL.r and USER.r files.

I would like to see another "hook" to allow "Back-end" code to execute 
automatically whenever Rebol stops its current evaluations for any 
reason such as encountering the HALT, QUIT, or any error which causes 
Rebol to stop evaluation.  


This could allow for some kind of automatic logging of  QUIT, HALT 
or ERROR as well as capturing the error messages.  It would be nice 
to allow capturing of any other information such as the script name, 
computer name, current timestamp, and where in the script the evaluation 
stopped, and how it stopped.


I would use this to log all of my scripts that is invoked (put the 
code in REBOL.r file) and then the termination conditions defined 
so they could be triggered automatically.  With such a function, 
I could even have certain selected scripts send an automatic SMS 
messages to my phone if certain scripts errored out etc.



I'd like to propose a new function called WHEN that can be used to 
trigger code at a terminating event.

WHEN  block  /all

For any specified terminating condition, evaluates what follows it.

Arguments:

block [block!] - Block of terminating events (conditions followed 
by values)
Refinements:

/all - Evaluate all terminating conditions (do not stop at first 
true terminating condition)


The WHEN command would be used to define code to be evaluated whenever 
a termination condition of any kind occurred in which continued evaluation 
will stop.

Examples:
WHEN/ALL [

 HALT?	[ print "This script will HALT now" ]  ; code to be evaluated 
 before the HALT is evaluated

 QUIT?	[ print "This script will QUIT now" ]   ; code to evaluate 
 befoe the QUIT is evaluated 

 ERR?	[ print "An error was discovered"  ]   ;code to evaluate after 
 an error is captured, but before the message is printed
	END?	[
		  print "Script about to end"
		  if  now/time  >  23:00:00  print "Stopped after 11 pm"

  ]                                                              ; 
   code to evaluate whenever the current evaluation has stopped for 
  any reason
	]


Note:  HALT?, QUIT?, ERR?, END? are all logic values which become 
true depending upon how evaluations will be stopped.

END? will always be true and one of the other terminating conditions 
will always be true.

What do you think?

Question: I created my fork.

And now I created a branch on my computer, but where am I supposed 
to work exactly ? 

I mean, I only see the source files in a sub dir called /red-system

It's amazing how much more approachable this system is compated to 
everything else out there - save for the very early teaching examples 
in computer science history

I.E: the rebol's VM size is small, that's an adventage if I work 
on a computer with 1.44Mo flopydisk as main support, it's just stupid 
if I have 1Tera e sata hard drive. Or rebol vm runs everywhere your 
script the same, you take area-tc and surprise it doesn't work on 
windows seven on linux and macOS X.  Or it's easy to do networking 
with rebol. If you do TCP or UDP yes if you do something else you 
are unable to proceed ... see that's always double side half truth 
in rebol and that's really what I don't want to see in Red this is 
not a big contribution but it's important enough for me to be said.

Well the claimed speed improvement is confusing me.
R3 slower than R2 on the Geomol's computer, uh !

And sorry but I also think that the memory footprint of the bytecodes 
is outrageous :-)

It's not really junk!, it's human text, encoded as humans see fit, 
gibberish or deep meaning symbolic.

Funny, when I first implemented KWATZ!, I called it gibberish!, but 
I found KWATZ! better suited and more interesting. And it kinda give 
you the same feeling, as when you see a computer go down with a "Guru 
Meditation". :)


And if you don't mind, I may start poking around in your wiki as 
btiffin on GitHub. Feel free to tear any writings apart.

The idea with the wiki is, that it's for everybody to edit, so it's 
not really "mine". And as I have very little time for documentation 
right now, I will only contribute a little. It may be needed to step 
in at some point and clear things up, make different pages consistent 
with each other etc., and that may be me, who does that, but it could 
be somebody else too. For the dictionary, it may be an idea to write 
a script, which does most of the documentation (I think, there's 
an old REBOL script for that lying around somewhere, which may be 
suited with some modification). system/words may be needed to do 
that properly, and that's not in World yet. I produce LaTeX output 
with my NicomDoc format, so I'm covered there with the documentation, 
I'll do (a proper manual).

Regarding cortex.w - is that in the far-plan?

Yes, the binary will be as basic as possible. I even consider removing 
definitions of natives from the binary, as it's possible to define 
them in cortex.w. Same could be done with datatypes with a little 
change to World. Then the binary could only define MAKE and DATATYPE! 
(and probably also SYSTEM), and the rest could be build from that. 
It's a good idea to split the doc up in a native section and a mezzanine 
section. And then there's rebol.w, which will make it possible to 
run even more REBOL scripts. There could be a dictionary for that 
too.
