iPad's competitor from RIM

[viktoras d.]

 IPad soon will have a serious competitor - PlayBook from producers of 
Blackbery:

http://na.blackberry.com/

Will Revolution, oops, LiveCode run on that (QNX Operating System)? It 
claims to be Flash compatible as well.

Re: E-mailing data file

[viktoras d.]

Hi Charles,

what if, instead of sending data as an attachment of an e-mail, user 
saved data into a ftp directory on a web server. In this case the only 
thing to send would be the url or name of data file. Of course in this 
case you will need to ensure 24/7 availability of your ftp directory. 
However this scheme simplifies implementatin and would not even require 
any cgi coding at all.

Thank you Colin, Mark!

Changing point of view is refreshing! I rolled out a solution which is 
getting unreasonably complex using all the revXML stuff and finally got 
suck... Now after seeing your examples I  realized that the simplest way 
to display xml with known schema is to transform it by simply replacing 
xml tags with html in the source text and setting htmltext of field to 
it (!).

I'm not sure this can be done in one line, but...

place a browser control and a button onto your stack and then:

local tBrowserID

answer file "where is the file?"

if it is not empty then
put revBrowserOpen(the windowID of this stack, "file:" & it) into

revBrowserSet tBrowserID, "rect", the rect of image "browserimage"

The specific 'bits' that grabbed my attention were these:

"HyperNext V4 coming soon! "

and

"Coming soon - with many enhancements and versions for

Mac OS X - Intel native builds.
Windows 7.
Linux beta."

Now as this is, as far as I can tell, a one-man, kitchen-sink operation
(Um; how did RunRev start?) and Hypernext is, at present, FREE, the
developer is under no real need to keep punters happy, so, also
"coming soon" could be extremely subjective.  I have written to
the info address asking about time-frames.

The thing that interests me most is that there is a Linux version in 
the pipeline.


Now at a time when 'some' IDE development companies seem to be slacking
off on Linux development here's a person doing quite the opposite (of 
course

as s/he in non-commercial we cannot assume her/his motives are the same
as commericla operations); presumably this is not just for the fun of

after all porting all that stuff over from Mac and Win to Linux may 
not be all that easy.


This company needs watching as they may yet produce a viable competitor.

Hi Randal,

you
can only shell out commands to it. It would be *very cool* to get this

One more alternative is to use netpbm (http://netpbm.sourceforge.net/).

Re: Language comparisons: "Lua" - simpler and faster than RevTalk?

[viktoras d.]

the sad fact is that many languages out there have a simpler mechanism 
(implemented via libraries) to access and manipulate image pixels. 
RevTalk does not have such a library and manipulation of image pixels is 
therefore unfortunately very slow and awkward :-(


A year ago I put a suggestion for an enhancement in the QC for "more 
efficient pixel access in images" #7636.
However its status is still unconfirmed. Maybe I have to change severity 
from enhancement to critical to make this report more noticeable :-)

Wilhelm Sanke wrote:
A quote from a website: "An increasing number of software developers 
are making use of the simplicity and power behind employing a Lua 
script interface".


I came across "Lua" when searching for image-filter algorithms on the 
web.


"Lua" is being described for example as "an extensible extension 
language (especially for C-languages)" and is written in C itself - 
similar here to the Rev engine which is written in C++. Generally - 
judging on the basis of my limited experience with Lua - I do not 
think that Lua is simpler than RevTalk, but when it comes to image 
processing a few features stand out as even more "higher-level", and 
in that sense "simpler", than RevTalk.


As Lua remains nearer to C, I assume that the execution of Lua scripts 
will be faster than such written in RevTalk. I do not know whether Lua 
scripts are compiled at runtime or build time.


A number of image tools integrate Lua in the form of flter plug-ins or 
for other tasks:


- "Adobe Photoshop Lightroom" uses Lua for its user interface and to 
create plugins (see the "Lightroom SDK Guide").


- "Gimp", the open-source and cross-platform Photoshop competitor uses 
"Gluas", a Lua environment plug-in - ("Gluas is a GIMP plug-in 
providing an environment for testing algorithms for image processing, 
using the Lua interpreter. The environment contains a simple editor 
for entering the algorithms.")


- "DogLua" is based on a 'gluas' plugin spec developed initially for 
GIMP.


Other programs in this category are

- "Dogwaffle",  "Artweaver", "Anim Studio", "TwistedBrush", "TexGen 
0.61" ("is designed to meet all your needs of creating textures"), and 
also a new "Lua Image Processor".--


I want to address here only three aspects of Lua:

1. Coordinates of pixel positions and its RGB elements

A typical skeleton script in Lua looks like this:

 "for y=0, height-1 do
   for x=0, width-1 do
r,g,b = get_rgb(x,y)

-- do your stuff here, in this case
-- process the rgb values

 set_rgb (x,y,r,g,b)
end
   progress(y/height)
  end"

A near equivalent to this in RevTalk would be:

"repeat with i = 0 to theight -1
  repeat with j = 0 to twidth -1
   put chartonum(char i * twidth * 4 + j * 4 + 2 of idata) into R
   put chartonum(char i * twidth * 4 + j * 4 + 3 of idata) into G
   put chartonum(char i * twidth * 4 + j * 4 + 4 of idata) into B

-- manipulate the RGB values here

   put numtochar(R) into char i * twidth * 4 + j * 4 + 2 of idata
   put numtochar(G) into char i * twidth * 4 + j * 4 + 3 of idata
   put numtochar(B) into char i * twidth * 4 + j * 4 + 4 of idata
 end repeat
end repeat"

To speed up this Rev skeleton script the computations could  of course 
be condensed and placed also outside the inner loop, at least partially:


"put twidth * 4 into trow
repeat with i = 0 to theight -1
 put i * trow into ti
  repeat with j = 0 to twidth -1
   put ti + j * 4 into tij
   put chartonum(char tij + 2 of idata) into R
   put chartonum(char tij + 3 of idata) into G
   put chartonum(char tij + 4 of idata) into B

-- manipulate the RGB values here

   put numtochar(R) into char tij + 2 of idata
   put numtochar(G) into char tij + 3 of idata
   put numtochar(B) into char tij + 4 of idata

 end repeat
end repeat".

It is obvious that Lua needs only the two plain x,y coordinates to 
determine the position of a pixel and its RGB components. The more 
complex computations necessary in the Rev script are running 
internally "under the hood" of Lua - predefined in C, meaning that in 
this case Lua is using syntax elements of a higher level than Rev.

If you want something small, light and customizable to start from, there is

Re: Rev for Linux (was Re: iPadding around?)

[viktoras d.]

what about creating our own Debian based Linux distribution?.. We would 
give it a name of Revolinux with most of the system management utilities 
(or GUIs for these) written in RevTalk, its own software repositories. 
This would provide a lot of opportunities and motivation to test and 
polish Revolution on Linux. Revolution engine could also be an integral 
part of the distribution, well, the paid version of it ;-). And it could 
be released with integrated and pre-configured onRev server as well.

Sarah,
I aggree that the iPad offers an opportunity for Rev developers once
RevMobile is there and working. As you mentioned the in-house market and the
vertical market will have a device that can change a lot of workflows. 


Just consider connecting a bar-code scanner to the iPad and you have an
inventory system that can very well be integrated into an existing IT
infrastructure.

Or consider connecting a credit-card reader/mobile printer and you change
your whole buisiness from a fixed point of sale to a mobile one as Apple
does in its stores.

Consider hospitals with their need for mobile access to data and data input.

I know of some buisinesses that are just waiting for a device of that form
factor to change the way they do their retail and inventory.

Since I have the feeling that Rev is mostly used in vertical markets and
seeing how these markets have a tendency to go mobile this might well be an
opportunity for Rev developers.

And although I see some problems with the Appstore, as far as distribution
of software especially for small companies and even single person companies
it takes a lot of problems out marketing a product.

From the help text:

This stack is a tribute to the memory of Bill Marriott — one of his 
last little side projects was the initial Mandelbrot Explorer stack, 
which he offered to the RunRev mailing list as an example of the power 
of the Revolution environment. Bill worked out the calculation 
handlers after teaching himself the basic math of complex numbers in a 
few days, and put together a stack that created black-and-white images.


With the view that a fitting tribute to Bill's memory would be a Rev 
project, I expanded his stack to create color images, moved the 
controls into a palette, and stored the calculated dwell values in a 
customprop so that colorization could be adjusted without 
recalculation, which speeds things up considerably especially for high 
iteration parameters. The colorization scheme is mine but many other 
algorithms are possible.


Bill's contributions to RunRev will long be with us. His brief foray 
into fractals was a tiny sideline, but when you use this stack you can 
remember him.

[OT] dedicated server hosting in the UK, Australia and the USA

[viktoras d.]

sorry for this off-topic. I am struggling to find out prices for 
dedicated hosting on virtualized Linux servers and many hosting websites 
seem to hide their prices. Many of them offer to fill up a questionnaire 
with server configuration settings so they can call back and negotiate 
the price. This is quite unusual for me as pricing plans in my own 
country are not usually treated as commercial secrets or something that 
is hidden from customer and look like this:


plan
D10 > 10 GB 256 MB > 3 Mbps 30% Xeon 29 Lt/mėn. (7.6 £/month)
D20 > 20 GB 512 MB > 5 Mbps 40% Xeon 39 Lt/mėn. (10.2 £/month)
D30 > 30 GB 768 MB > 7 Mbps 50% Xeon 49 Lt/mėn. (12.8 £/month)
D40 > 40 GB 1024 MB > 9 Mbps 60% Xeon 59 Lt/mėn. (15.5 £/month)
D60 > 60 GB 1536 MB > 12 Mbps 80% Xeon 79 Lt/mėn. (20.8 £/month)
D80 > 80 GB 2048 MB > 15 Mbps 100% Xeon 99 Lt/mėn. (26.05 £/month)
G100 > 100 GB 4 GB > 20 Mbps 2 x Xeon 299 Lt/mėn. (78.68 £/month)
G200 > 200 GB 8 GB > 40 Mbps 4 x Xeon 399 Lt/mėn. (105 £/month)

G400 > 400 GB 16 GB > 80 Mbps 8 x Xeon 599 Lt/mėn. (157.63 £/month)

Can anyone tell what the prices are for anything like plans in between

Re: [Mandelbrot] Code Samples/Comparisons

Well written! It was a pleasure to read, you need to put at least part 
of this text somewhere on the http://www.runrev.com/ website :-)


All the best!
Viktoras

Bill Marriott wrote:


Thanks so much for taking the time to do this! But I think it's a *great*
example, and I am going to show you why.

Let's start out with a few observations:

- How "practical" is this? I took a closer look at the site.

http://shootout.alioth.debian.org/u64/benchmark.php?test=mandelbrot&lang=all&box=1 



The goal of the routine is to generate a mandelbrot image in the .PBM
format. Now, this has some relevance I suppose in testing CPU 
performance,
but not exactly in the real world. How many programs read PBM, for 
one? None
on my Mac, but Photoshop and Paint Shop Pro could read it on my 
Windows PC.

How fun is it to run this program, then load the result up in a graphics
editor? About as much fun as punch-card, batch programming.

- The original Pascal program (or at least your transliteration of it) 
*has
a bug!* Give the output file an extension of .pbm and load it into a 
program

that can read that format. You'll find that the image is skewed more and
more as the dimensions increase.

http://revuser.com/mandel/orig-600.png

In either Pascal or revTalk, as coded, it's going to be a challenge to 
find

out where that bug lies.

- It doesn't seem like it was that hard to "transliterate" the original
Pascal code. I was impressed by the similarities, actually. Even then, 
there
are portions of your revTalk version that are a little more readable. 
Since

the vast majority of this is mathematics, and we're not out to reinvent
algebraic notation, you're right that it's not the best showcase. Math is
going to be math in any programming language. It's certainly not *less*
readable. What makes it hard is the Mandelbrot formulas and especially 
the
encoding into .pbm format (which is what requires all those bit 
operations.

(Maybe all of the examples from that site are like this?)

- Pascal is considered a pretty "easy" language. Did you check out 
what the

"solution" looks like in Java?

http://shootout.alioth.debian.org/u64/benchmark.php?test=mandelbrot&lang=javaxint&id=3 



In C++?

http://shootout.alioth.debian.org/u64/benchmark.php?test=mandelbrot&lang=gpp&id=5 



Woah! :)

- Well our performance is a is a bit disappointing relative to the 
"command

line" Pascal version, we *do* beat out variants of PHP, Python, Ruby, and
Perl, depending on what your processor was versus the one used for the
benchmarks.

- You were able to add a nice GUI file selector dialog trivially. Now,
imagine that your goal isn't to produce a .pbm image, but rather to show
something on-0screen the user could interact with in some way. Things
get more interesting. This is where Rev starts to shine. The
further away you get from "pure" math and have to get into user 
interface,
interaction with local and remote file systems, manipulating data 
sets, and

business logic issues, the better we look. Our language abstracts the
operating system, so developers don't need to be concerned with the 
proper

API to call for common tasks.

- Most (but not all) of us are not using Rev to generate Mandelbrot data.
We're creating usable applications for business tasks, entertainment and
educational software, database front-ends, etc. It might well be that 
this
site/link is all about these kinds of math-intensive routines. I 
didn't look
too closely at them, admittedly. What I did like about Viktoras' 
suggestion
was that he found a site with some sample code in a variety of 
languages. I

think it's healthy for us to look for such examples and discover the
strengths and weaknesses that emerge when we try to express them in 
revTalk.


My take on the "productivity" equation is that it's not merely the 
number of

lines of code produced, and it's ultimately not even how fast the code
executes. In most situations, it's how long it takes to express the
algorithm, and debug it later on. To encapsulate algorithms in 
flexible user

interfaces. To take things to an extreme: a routine
built with machine code or assembly will always execute faster than one
built in a high-level language. But how many of us could sit down and 
write

a database front-end in assembly? How long would it take? How usable and
adaptable would it be?

Another way to look at things is from the artist's viewpoint. There are
people who will never touch digital photography because they are 
expert at

the analog process. There are illustrators who will never give up their
charcoals. There are Lego builders who spurn the non-rectangular 
bricks! And

thank heaven for them, because I respect the desire for control and
attention to nuance. In a similar vein, other languages can indeed reward
sweating details like what kind of number you're trying to store, 
manually

allocating and releasing memory, etc.

We're not promising to be the tool that lets you rewrite OpenGL or even
build a competitor t

Re: Code Samples/Comparisons

[viktoras d.]

what about using task/code examples from 
http://shootout.alioth.debian.org/. Revcoders (us, runrev ltd?..)  will 
still have to write quality examples in Rev which would be a challenge 
:-) Quality of the code there is good enough as computer language 
benchmarks game aims to create the shortest and fastest running 
executables for all the open source languages out there. So both number 
of lines, speed of execution and memory use are taken into account..


I think for the community of revcoders it would be interesting to 
compare revTalk in that context too :-).

Bill,

I will say the same thing I said to Kevin's recent post:

The


question we were asking was "Which language is going to be easier in day to
day use"? For example, the code on the PHP comparison was based on an
example posted on a site that *teaches* how to write PHP. So clearly its of
a standard that is used in the real world. If you're an expert coding in
PHP
every day you can shorten it. Same with the revTalk example as it happens.

  

What is simply needed is a bibliography.

The fact that the PHP example comes from a site that teaches PHP is a huge
blow to any argument that Rev is manipulating example to their own benefit.
But that fact is not evident on the pdf.

We don't need Rev users to 'create' examples, no matter how real life they
are, as they will always be subject to the 'they've been manipulated by Rev'
accusations.

Better to find on line examples of code in each of the languages listed,
especially from sites that supposedly 'teach the language', and then do the
Rev equivalent.

If I were to manipulate anything, I'd then try to include these examples on
'teach Rev' sites, like Devin Assay's, and include that in the bibliography
as well.

As, has already been said, you are not going to persuade the 'real
programmers' by line counts and code readability, and they'll continue to
argue that the code examples are poor and they can do better. But for anyone
new to programing, or actually open minded enough to be considering any or
all alternatives, links to real examples of other language code and learning
sites, and actual equivalent examples in Rev are going to be effective, and
if they follow the links to Learn Rev sites, lead them to the next step down
the path of giving Rev a try.

illustrations of how revTalk can be shorter and/or more readable, please
either post them to the list or mail directly to me -- bill.marriott (at)

If you are able to replicate the functionality with a revTalk example, all

programming challenges, things everyone building software can relate to. And
of course, areas where revTalk really shines.

While it won't be the same as getting "recognized experts" [in those other

Whatever the answer, Andre raised a very relevant point, with which I
  

fully agree, that Rev is not well served by using a comparison against what
others feel is very poor code. [...]

To truly demonstrate Rev's ability against other code, get the code
written by a recognised expert in that language (somebody like Bruce Eckel
for Java and C++). Yes, it would cost money but I believe it would be money
well spent.

Re: Rev 4.0 article on TheServerSide

[viktoras d.]

...a few more thoughts related to making revTalk sound more 
"professionally".  Description of programming in revTalk as English-like 
might sound OK and attract masses of beginner programmers from the UK, 
USA, Australia or New Zealand but it can also be rephrased into a 
description which would have more appeal for experienced programmers 
worldwide. I guess it would be more useful to emphasize revTalk not as 
"unprofessionally" "English-like" but as "very proffesional" "*Literate 
programming*".


Here it comes, the definition 
(http://en.wikipedia.org/wiki/Literate_Programming): "The literate 
programming paradigm, as conceived by Knuth, represents a move away from 
writing programs in the manner and order imposed by the computer, and 
instead enables programmers to develop programs in the order demanded by 
the logic and flow of their thoughts. Literate programs are written as 
an uninterrupted exposition of logic in an ordinary human language, much 
like the text of an essay."

Re: Interactive image overlays

[viktoras d.]

I am also always using graphics, not images when I need to display 
clickable or non-clickable irregularly shaped regions of larger images 
(maps, species pictures, etc.) It is very convenient, indeed, and it is 
easy to make them more responsive to user actions like for instance 
changing colors of border or background on mouse enter, mouse click, 
mouse leave, etc... Or even darkening color with each iteration of 
displaying, so that the first polygons displayed become gradually 
darker, and the last are always the most bright ones :-)

BNig wrote:

it is well known but often overlooked that when using a graphic
(transparent/noop) as an irregulary shaped 'hot spot' over an image that you
can put two or more irregulary shaped areas into one graphic. You can do
this by putting the points of the second graphic after the points of the
first graphic but you separate them by an empty line.
For example you have a map and you want to make the USA clickable but Alaska
and Hawaii are not part of the contiguous USA. In that case you could make
one graphic with the points of the continental USA appended by the points of
Alaska and the points of Hawaii. You would only need one graphic to take
care of the clicks to the USA.

on mouseLeave
   set the ink of me to "noop"
end mouseLeave

  

in the behavior of the overlay graphic.

Re: 3D in Revolution Needs Your Help

[viktoras d.]

Hi Lynn,

For some reason my messages bounce from the use-revolution server. 
Trying again...


Err, I was in that list too, but now, pressed to the limit by 
consequences of the economical crisis, I moved from one country to 
another which does not happen too frequently in ones life. Will be 
paying as soon as I am able to do this... B.t.w. I tried to register 
with the system and submit the bugs, but later it won't let  me in with 
my user name and password, so there are things that does not work as 
expected. I also think it is worth considering Bryan's suggestion of 
lowering the price tag - this would attract more than just 15 "of us".


All the best!

Hello all,

Several months ago we set up a team to create Franklin 3D, after talking
with quite a few Revolution users about a founder's program. Franklin 3D
adds a powerful 3D game engine to Revolution. This is all following
conversations Ive had over the last several years (quite a bit at the Las
Vegas RunRevLive) about having 3D support for Revolution.

My team at Paradigma, as most know, is focused on the database market. We
put together a separate team to tackle this problem.

We set up a founder's program so that we could pay for an engineering team
to bring this product to fruition on Windows and Mac OS X for a 1.0 release.
About 15 people in the community said they would participate when it reached
a beta release, and pre-purchase Franklin 3D to help this happen. This
number is about 1/3 more than what we need to complete. Founders get the
full year of updates after release, plus have a direct voice in the features
we incorporate into 1.0. Future features are driven by customer feedback. We
have a private beta list ready for those who participate.

The Windows version beta is available for download on the Franklin 3D
website at http://www.franklin3d.com. The Mac version is the one that has
the biggest cost - at this point, I can say it compiles, and we are
estimating 2-3 months to deliver the 1.0 Windows AND Mac OS X release. This
project is driven solely by our ability to pay the developers for their
work.

We reached the point about two weeks ago, and unfortunately none of those
who said they would participate have placed an order yet.

We need your help in bringing this to fruition. If you previously said you'd
pre-purchase, please follow through and do it. If you have an interest in 3D
games or 3D simulations, check it out at http://franklin3d.com/.

If you are one of those who asked for Linux after our first announcements of
the founder's program - Linux will happen only after a 1.0 launch. The best
way to have a say in a Linux version is to participate. A Linux version will
never pay for itself unless its part of a complete platform launch.

Re: Performance of RevMedia on matrix diagonalization

[viktoras d.]

Hi Piero,

declaring local/global variables in functions and handlers should 
slightly add to speed. Populating arrays in advance with zeros so that 
array size won't change inside loops might also be of some value. 
However, please correct me if I am wrong, VB6 is compiled while 
Revolution is interpreted, therefore much slower. Did you try 
implementing same algorithm in other interpreted languages (javascript, 
php, perl, etc?) it would be interesting to do some benchmarking :-)


Using native functions: matrixMultiply(firstArray, secondArray), 
transpose(array) where possible would also increase speed as they are 
really fast.


Best wishes

I am completely new to Revolution. I have downloaded the RevMedia alpha
version and played a bit with it. I was impressed by how fast I was able to
port a little VB6 code to RevMedia. This code diagonalizes a symmetric
matrix using the Jacobi algorithm. I checked against the VB6 code and I got
exactly the same results in the same number of iterations so that numerics
is the same. However the RevMedia code is at least one order of magnitude
slower than the VB6 one. For instance a 50x50 matrix is diagonalized in a
couple of seconds in VB6 and it tooks more than a minute on RevMedia. I know
that RevMedia is not meant for numerical intensive calculations; however, I
would like to use it in a scientific teaching context so some power is
needed. I wonder if anybody much expert than me can try the code using the
most powerful Revolution Studio and if there is a clever way to deal with
matrix algebra.

Re: Transcript should be called Transcript

[viktoras d.]

Hi Richmond,

quite possibly. I found something like this while googling for revTalk 
(sorry I am not sure if this is correct ):
Le language, nommé /revTalk/, utilise des phrases en anglais, ce qui 
réduit la complexité de développement d'applications.


While it is true it is somehow out of context in the sentence which is 
written in French. Being a non-native English speaker I would possibly 
prefer "Human language-like programming language" otherwise one assumes 
he must first learn English before he can start writing software in 
revTalk. Besides it is not the reason some of us started programming in 
revTalk. Completeness and simplicity of the development cycle for GUI 
software for 3 platforms is the likely reason. In fact most other 
programming languages and SQL are also based on English language syntax 
so it is not a unique feature at all ;-)

Re: Transcript should be called Transcript

I usually say "Runtime Revolution IDE". Most people here (in Europe) 
have at least heard about it. But it is called Revolution in the tiobe 
programming community index 
(http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html). And 
there is absolutely no reason to avoid word "script". Not the name of 
the language but the result of its use in business is what matters... 
There are other languages widely in use with non-aggressive and totally 
non-cool names also including the word "script" like Smalltalk, 
JavaScript, JavaFX Script, ABAP, Lua, Ada, Alice, Focus, Groovy, Boo, 
Clean, Euphoria, Squirrel and even MOO and MUMPS (!!!) etc...

Re: Releasing Memory and Virtual Memory

OK, that's also possibly why I have been experiencing strange crashes 
upon loading large images into a hidden stack, reading their image data, 
importing RGB values into a table in sqlite database, deleting image and 
closing. Then if I open another image within the same handler 
application mysteriously crashes PC with 2 GBytes of RAM... Vote cast.

I certainly have run afoul of this problem, that there is no garbage

enough job on a machine with small enough memory, caused the app to 
crash.

There are certainly ways this behaviour could be improved, without

Re: Edu Ware Revlets

[viktoras d.]

Hi Sivakatirswami, thanks Malte!

I told its half-baked :-). Here it loads on 3 out of 4 computers, so 
something is going wrong in certain cases. Maybe, as Malte pointed out, 
system setup or stray processes are to blame. Occasionally I notice some 
strange interaction with flash - complex flash animations become jagged 
when revolution is loaded. But as revlet technology is in its 
pre-release stage, I too feel very optimistic about its future.


Best,
Viktoras

Did you happen to have had another revLet open in the same browser 
session? I do see revlets hang on load sometimes and I would be 
interested if others had too. A Browser restart (and killing 
eventually remaining stray processes) does fix the problem, but for 
sure I have seen loading just halt. I am not too scared about that, 
given that the plugin still is pre release Software though, but maybe 
it is worth to mention, because maybe it has to do with some system 
setup.


@Viktora:. Impressive stack. Very nice. It took quite a while to load, 
but the result is awesome.

Hello all,

A quick update on Franklin 3D - the 3D game and rendering engine for
Revolution.

We are going to be able to expose Franklin 3D for Revolution very soon to
founders - I want one more example stack update. We have demo stack just
about ready - some tasty bits:

- Rendering includes OpenGL, two "software" renderers and Direct X 9
(Windows only)
- Loading a Quake Map
- Unnative UI (there is a UI engine built right into it)
- 2D sprite engine
- Collision detection/gravity
- Custom Scene Nodes
- Movement
- Terrain Rendering
- Rendering to Texture
- Split Screens (more to come on this - shows multi camera views - maybe
multiplayer games...)

Some of the effects aren't quite right yet, that's why the delay.

That's the first batch of examples. There's one in the works that show how
to handle call backs - several more coming.

The demo stack will let you locate the media folder, select windows size,
select renderer.

Here's my top five Why This is Cool:

- hardware accelerated graphics - both 3D AND 2D
- lots of model formats supported, game and not game (like OBJ)
- OpenGL gives you a great cross-platform option when the Mac OS X version
is available
- A lot of stuff like collision detection/gravity is REALLY easy
- Useful for simulations, 3D viewers for graphics catalogs and more

Founders will be able to pre-order, get codes right away and get into a
private Google Group. Licenses will include 12 months of updates. The
licensing system will be very similar to how Valentina works.

Ill post other details soon.

People sometimes state funny "facts" or ask questions about my part of

to :-) . B.t.w we are not that far away on the edge of the world (check 
wikipedia entry on Geographical Centre of Europe or the Guinness Book of 
World Records on same subject), country is a member of the EU and NATO.


On the other hand if somebody asked me facts about Georgia, my first 
thought is far from the USA, I would not be able to list all names of 
the USA states or presidents, or even capitals of all Balkanian 
countries that make part of the Europe without digging deeper into my 
memory or asking google. Therefore I think this lack of knowledge is 
quite normal. Although the funny (and still somehow unpleasant) part of 
it is that "unknown" = "wild, uncivilized and dangerous place"

I had questions on politics and geography from hundreds years past for
countries such as France, China, India. Questions about the russian
revolution and african cleptocracies. Now, people can't locate my
country on a map... at least people know where Scotland is...

Re: RGB values for a color name

[viktoras d.]

what abou this: http://www.w3schools.com/HTML/html_colornames.asp ?

well you'll have to translate color names from hex, make an name-rgb 
array and get value for name (put array[color_name] into rgb).

TWAIN shell

[viktoras d.]

I found a piece of software that should allow me to automate 
communication with any TWAIN imaging device (camera, scanner, etc) from 
within my Rev applications on Windows: 
http://www.dosadi.com/acquire.htm. Unfortunately it is not free and 
limited to MS Windows only.


Does anyone know anything better than this ? Any TWAIN-like standards 
and related command line utilities to access imaging devices on MacOSX? 
Linux?

Re: Inefficient code - Solutions

[viktoras d.]

if binaryEncode allowed using an array (like binaryDecode(C*), the 
imagedata of img "myImg", outArray) instead of a predefined list of 
variables, then it would be possible to use array multiplication to 
extract and compare parts of an image e.g. multiply by [1,0,0,0] for 
alpha, [0,1,0,0] for red, etc. But it is not possible and running the 
loop to convert imageData to an array will be a major speed limitation 
anyway.


Some time ago I filled up an enhancement request 
http://quality.runrev.com/qacenter/show_bug.cgi?id=7636
. Or as said above a feasible alternative would be possibility to use 
arrays or at least lists in binaryDecode.

Re: my sqlite code is slow :(

[viktoras d.]

Hi, Björnke

make sure the "begin" and "commit" part is outside any loop, eg.

revExecuteSQL yourDbID, "BEGIN"
#loop starts here
repeat for each...
revExecuteSQL yourDbID, "INSERT INTO table VALUES()"
end repeat
#loop ends here
revExecuteSQL yourDbID, "COMMIT"


Without begin-commit stated explicitly, SQLite automatically does 
begin-commit for each insert statement and this is why it slows down  to 
1 insert per 1 hard disk rotation :-).


Viktoras

Björnke von Gierke wrote:
It seems that revcommitdatabase is doing the commit part, but not the 
begin part, and therefore it's utterly useless, am I seeing that right?


I tried to use begin/commit transaction, but it seemed to slow down 
even more. but i didn't experiment with that aproach much, so I 
understand that I am on the right track, and should be able to speed 
it up, if I'd use begin/commit correctly.

get the defaultFolder

When Revolution application starts up, the defaultFolder initially

standalones it  points to working directory of standalone application 
(if not changed by script).

Re: bignum unicode entities in htmlText?

[viktoras d.]

Thanks Devin, Richmond for even more hints!

Now I have my script almost working, it has to display both unicode and 
non-unicode in the same field, so I did this:


set the useUnicode to true
  set the itemdelimiter to "&"

  repeat for each item myItem in myInText
 if ";" is the last char in myItem and "#" is the first char in 
myItem then

put numtochar(char 2 to -2 of myItem) after myOutText
 else
repeat for each char myChar in myItem
   put myChar & null after myOutText
end repeat   
 end if
  end repeat  
set the unicodeText of fld "f1" to myOutText  

unfortunately it still leaves the last unicode entity undecoded in each 
unicode string, besides I would need special formatting of the output, 
so I will definitely need to think more :-).


Devin, the database is not mine (it belongs to the species2000 project), 
so I can not change anything what's inside, only try to display its 
contents. Now I wonder if MySQL itself has any function to do the 
decoding of these html entities in SELECT statement...


Richmond, I still have Revolution 2.6 besides the 3.5, so I haven't 
burnt all bridges to the old revonline repositories yet. Nice example, 
btw. cool graphical background (where from (url) ?)!


All the best and thanks again for your help!

Viktoras,

I'm jumping in here late, but wanted to add, when you save your 
HTMLtext with Chinese characters, you need to make sure than all of 
the font tags are saved with it. It seems that when you're using 
Unicode embedded in HTML you also have to tell Rev exactly what font 
and language to use to display it. It ends up coming out something 
like this:


lang="zh-CN">您离开讲国


The font face attribute will of course determine the exact font, 
therefore the look of the characters. Make sure it's a font that you 
can reasonably assume will be on the target computer. The font lang 
attribute determines which variant of Chinese you use, Simplified 
(mainland) or Traditional (Taiwan primarily). For Simplified use 
lang="zh-CN". For Traditional use lang="zh-TW". Note that Simplified 
and Traditional Chinese fonts are not interchangeable. There are 
Traditional font faces and Simplified font faces.


By the way, here's how to get a list of Simplified vs. Traditional 
fonts on your computer:


   put the fontNames into tfonts
   repeat for each line tFont in tfonts
  if the fontLanguage of tFont is "SimpleChinese" then
  -- or use this test to find Trad.
  -- if the fontLanguage of tFont is "Chinese" then
 put tFont & cr after tList
  end if
   end repeat

Having said all that, it might be better in the long run to store 
your Chinese text in your database as UTF-8. To do so, just put your 
unicode text into a variable and upload it to a database:


  put unidecode(the unicodeText of fld "MyUniFld","UTF8") into myVar
  ## store the contents of myVar in the database

Then when you are retrieving it, you reverse the process. (You have 
to make sure that the textFont for the destination field is set to a 
unicode-compatible font first. Usually if you just put it back into 
the field you got it from it's fine.)


  set the unicodeText of fld "myUniFld" to 
uniencode(myDataFromDB,"UTF8")


As I've said before, Unicode and Rev play together fairly nicely if 
you understand some basic concepts and know Rev's quirks. See my 
article at http://revolution.byu.edu/unicode/unicodeInRev.php for 
more details.

Re: Remote database access: Update

[viktoras d.]

I am glad it helped! One handy option is to make a few copies of that 
script each for different level of access. Eg. one q1.pl which allows 
SQL SELECTs only, other q2.pl that allows UPDATEs and INSERTs, yet 
another q3.pl which allows even more control over the database (DROPs, 
CREATE's, etc). Just make sure passwords are different and the regular 
expression in "unless" clause is updated with all the corresponding 
suspicious  patterns to prevent:

unless ($q=~m/pattern1_to_prevent|pattern2_to_prevent|etc.../i)

All the best!

Re: Remote database access: How?

[viktoras d.]

Maybe this has to be put into its own separate thread, but as it relates 
to MySQL anyway, here at

http://www.ekoinf.net/TxNav/
is a new dirty application of mine (released last weak, just before the 
e-biosphere09 event in London) to explore the Catalogue of Life 
taxonomic database. It is open source, so the dirty internals and the 
code is not encrypted. So far this is the only application for 
exploration of the Catalogue of Life on Mac.


The CaO database aims at collecting names and taxonomy of ALL living 
species on our planet (plants, fungi, insects, fish, viruses, bacteria, 
etc, etc). It has already accumulated 1 160 711 species which is more 
than half of all species known for science today. However if you dive in 
the coral reef you may see dozens of invertebrates that are not yet 
formally identified or described, so the numbers of unknown species are 
also very big numbers. The ISO image of the database can be downloaded 
from http://www.sp2000.org/. Database is in MySQL format.

Re: Remote database access: How?

[viktoras d.]

Hi Teresa,

a hile ago I have produced exactly such application to one of my 
clients. Client downloads it, the app communicated with mysql database 
on a remote server. I used a relay script written in Perl (so it should 
work everywhere, because Perl is omnipresent nowadays). It will pass 
nearly all sql except for alter, truncate, drop, modify, create. User 
must post two parameters - pasword and sql query to communicate with the 
database. Unfortunately both are submitted as clear text

: q.pl?p=[password]&q=[sql query]
and gets back the resultset in form of tab delimited text.

Here is the Perl script's (q.pl) source:
#! /usr/bin/perl -wT
#above string should point to perl installation directory on your server

use strict;
use CGI qw(:standard);
use DBI;

print header;
my $sth;
my $q=param('q'); #reads query data
my $p=param('p'); #reads password
my @line;

if ($p eq "password_to_check_goes_here") #if submitted password is 
correct then...

{
unless ($q=~m/alter |truncate|drop |modify|create/i) #unless dangerous 
strings apear in query string then...

{
my $dbh = 
DBI->connect("DBI:mysql:database=db_name:host=localhost","db_user","db_password") 
or die "$DBI::errstr\n";

  $sth = $dbh->prepare($q);
  $sth->execute();
while (my @line = $sth->fetchrow_array)
  {
  if (@line) {print join("",@line)."\n";}
  }
 $sth->finish();
$sth = $dbh->disconnect();
}
else
{
print "\err.#1000: Access denied"; #Wrong password
}
}
else
{
print "\err.#1001:\"$p\" Access denied"; #Potentially dangerous commands 
in query

}
exit 0;

and the clientside Revolution function (stack's script) is as simple as:

function Q vQ
local myServer
local myData

put "http://dommain.net/cgi-bin/q.pl"; into myServer
 put  "p=authentication password&" & "q=" & URLencode(vQ) into myData
  post myData to URL myServer
wait 1 sec
if it is not empty then

return it
  else
return "No matches found or timeout"
exit to top
  end if
end Q

Now it can send almost any sql statement or multiple statements and get 
back the result from any handler using:

get Q("SELECT * FROM invasions")

It works but sometimes timeouts may happen :-)...

Thanks to so many fantastic people in the Rev community. Special 
thanks to Geoff Canyon, Ken Ray, Trevor DeVore, and Richard Gaskin 
without whom I don't think I ever would have been able to do this.

Re: Arrays

[viktoras d.]

Hi Tom,

maybe something like this will do:
replace "Elliot and Cooper Roads" with "Elliot and Cooper Roads" && 
"[whatever needs to be paste]" & return in yourVariableWithData?

Tom Cole wrote:

Sarah,
Thanks. The sorts are MUCH faster when done in a variable. I'm not 
sure of the advantage of storing data in a custom property, but it's 
nice to know about. I'm forgetting arrays because now I need do only 
one thing to be burning through the data.


I have bird watching PLACES as one item. One is called Elliot and 
Cooper Roads. I've been to that street corner hundreds of times, and 
since I have seen over 8000 birds there, there are more than 8000 
records. I can put all of the records for this street corner at the 
top of the field (actually the "top" of the variable).



Elliot and Cooper RoadsFIRST VISIT TO THIS PLACE
Elliot and Cooper Roads
Elliot and Cooper Roads
Elliot and Cooper Roads
... thousands more
... thousands more
... thousands more
Elliot and Cooper Roads LAST VISIT TO THIS PLACE
Other Places
Other Places
Other Places

All I need is have a way to "cut and paste" from the first record for 
Elliot and Cooper Roads to the last and leave out the rest of the places.


Of course, I could write a repeating script that would gobble up the 
data a line at a time, but it would take forever. How can I scoop all 
the Elliot and Cooper records out of the data in one fell swoop?


If someone could show me how to do this, then I could employ it 
everywhere and my flat database would be screamin' fast and I would 
stay in Revolution.


I'm almost there!

Re: ODBC - Can use file DSN in Rev?

[viktoras d.]

a few years ago, before I learned Revolution, I did database 
applications for Windows in hta/javascript. It used dsn-less connection 
via ActiveX ADODB to a database where all tables were stored in plain 
text files. It could use Access files as well.


For plain text databases it was necessary to specify schema.ini file 
which needs to be put into the same folder with database tables. Here is 
an example of schema.ini contents:

[JoinedAquatics.csv]
ColNameHeader=True
MaxScanRows=0
Format=Delimited(;)
col1 = MasterID Long
col2 = CountryID Short
col3 = SpeciesID Text
col4 = EnvGroupID Text
col5 = FirstDate Short
col6 = SecondDate Short
col7 = VectorID Text
col8 = Vector2ID Text
col9 = ExpertID Text
col10 = VerifiedBy Text
col11 = Comments Text
[SpeciesData.csv]
ColNameHeader=True
MaxScanRows=0
Format=Delimited(;)
Col1=SpeciesID Text
Col2=Authority Text
Col3=CommonName Text
Col4=Taxon Text
Col5=Family Text
Col6=NativeHabitat Text
Col7=EcofunctionalGroup Text
Col8=NativeRangeTDWG2 Text
Col9=NativeRangeDetailsTDWG4 Text
Col10=NativeRangeInland Text
Col11=NativeRangeMarine Text
[SpSynonyms.csv]
ColNameHeader=True
MaxScanRows=0
Format=Delimited(;)
Col1=SpeciesID Text
Col2=Synonyms Text
[Countries.csv]
ColNameHeader=True

Here is the code snippet with some comments, database (folder with 
files) here is called "joined". Unfortunately I have never tried 
replicating this in Rev :-(:


function Dat_Q() {
MasterID = new Array;
CountryID = new Array;
Country = new Array;
SpeciesID = new Array;

<-snipping lots of variable declarations here->

// Create ADO Recordset
dbrcd = new ActiveXObject( "ADODB.Recordset" );

//Create the connection string
//this is how you would use Access databases:
//cString = "Driver={Microsoft Access Driver (*.mdb)};DBQ=Tables.mdb";

//and here is the actual code for text tables:
//cString = "Driver={Microsoft Text Driver (*.txt; 
*.csv)};Dbq=joined;Extensions=asc,csv,tab,txt;";


// Create SQL Statement
//sql = "SELECT habitat from tbTest";

if (sql) {sql=sql;}
else {sql = "SELECT COUNT('SpeciesID') FROM JoinedAquatics.csv"; 
QQ.SQLsent.value=sql;}


// Open connection to database
dbrcd.Open( sql, cString, 1, 3);
//dbrcd.Execute(sql);

// variable to store data
record = "";
// Loop through all the records found

while( !dbrcd.EOF )
{
  // Loop through each field in this record
  // and add contents to variable
  for( i = 0; i < dbrcd.Fields.Count; i++ )
   {
record+= dbrcd(i) + "";
switch (i)
{

case 0 : MasterID[sz]=""+dbrcd(i); break;
case 1 : CountryID[sz]="C"+dbrcd(i); break;
case 2 : Country[sz]=""+dbrcd(i); break;
case 3 : SpeciesID[sz]=""+dbrcd(i); break;
case 4 : Taxon[sz]=""+dbrcd(i); break;
case 5 : EnvGroupID[sz]=""+dbrcd(i); break;
case 6 : FirstDate[sz]=""+dbrcd(i); break;
case 7 : SecondDate[sz]=""+dbrcd(i); break;
case 8 : VectorID[sz]=""+dbrcd(i) ; break;
case 9 : Vector2ID[sz]=""+dbrcd(i) ; break;
case 10: PathwayID[sz]=""+dbrcd(i) ; break;
case 11: AlienHabitatID[sz]=""+dbrcd(i) ; break;
case 12: SpStatusID[sz]=""+dbrcd(i) ; break;
case 13: PopStatus2ID[sz]=""+dbrcd(i) ; break;
case 14: PopStatusID[sz]=""+dbrcd(i) ; break;
case 15: EcolImpactID[sz]=""+dbrcd(i) ; break;
case 16: ImpactOnUsesID[sz]=""+dbrcd(i) ; break;
case 17: InvHistoryID[sz]=""+dbrcd(i) ; break;
case 18: DonorArea[sz]=""+dbrcd(i) ; break;
case 19: NativeRangeMarine[sz]=""+dbrcd(i) ; break;
case 20: Reference[sz] =""+dbrcd(i) ; break;
case 21: Comments[sz]=""+dbrcd(i) ; break;
}
   }
  
  
  // Display the contents in Textfield
 
  //Move to the next record and loop

  dbrcd.MoveNext();
  record+="\n";
 sz++;
}

return (record);
}

function SQL_Q() {
sql=QQ.SQLsent.value;
QQ.QRez.value=Dat_Q();
}

In principle using this you could write database communicator ir jscript 
and communicate to it from within Revolution...

Re: Arrays instead of Sql

[viktoras d.]

Tom,

sort the data in variable instead of field using field only to display 
results, not for the data processing, or at least lock screen before 
sorting and then unlock screen. This will be much faster.


When putting data into field again lock screen and unlock afterwards. 
This will prevent field trying (slowwwly) to display its contents while 
these are being loaded into it.

I've written here before about a bird database I have. Several times.

I just have a few items in a record: 
birdname,birdnotes,place,placenotes,date  However, there are about 
18000 birds (records) and I've got them all in one field in Rev now 
and it's too slow to sort.


If I have to learn sql and so on, this may never get done, but if I 
stay in my familiar Rev environment I will be off and running. Is 
there a sample database stack where someone has used arrays to store 
the data for fast retrieval or some related script to help me learn 
how arrays could be used?


How can I place those records in arrays and then draw data to make 
cool sorts and views?  I'm not new at all to Rev; only to arrays.


I just need ideas on how to sort the data fast.

Thanks (again!)

Re: ODBC - Can use file DSN in Rev?

Hi Scott,

The simplest way is using SQLite files, then you even do not need ODBC, 
and this will be 100% crossplatform and works "out of the box".

Will Revolution work with a FileDSN to make an ODBC connection to a

I'd like to make my app self-contained and avoid making the user

Any knowledge out there on this subject?

Re: App on Linux - really slow... any ideas why?

[viktoras d.]

Hi, Ken,

same here.. When I did tests of my app on Puppy, it launches the 
splashscreen window and then crashes. Similarly on Slax, it starts and 
then crashes when the dropdown menu is being called. Both these Linuxes 
are based on slackware.


However the recent Ubuntu liveCD also prompts to choose Xorg or Vesa 
option, so you may wish to test it there too.


Viktoras


Ken Ray wrote:

ok, it should be very easy to test this.  Boot Puppy and pick the VESA
option.  Won't that tell you at least if its down to Xorg?



I DL'ed puppy, but I can't get Rev to run in it - it looks like it's
launching but never does; what do I need to do?

Re: App on Linux - really slow... any ideas why?

[viktoras d.]

PC Acer TravelMate 2300,  Celeron 1.5 GHz, upgraded to 2 Gb RAM. I 
tested my app (AALite sqlite database browser) on a few distributions 
and found that it is completely usable on  Ubuntu 8.10 Intrepid Ibex 
(Gnome), but starts and then crashes Puppy; starts, works but finally 
crashes on Slax (KDE), both are Slackware based.  Did not notice any 
large speed loss on Ubuntu or any other Linux distribution though... All 
these tests were done with operating systems loaded completely into RAM 
from liveCDs. I also removed all the options that I do not need at the 
moment when compiling (no printing, no fonts, no table) Going to do more 
testing on other Linux distros...


As far as I remember previously applications compiled with RR 2.6 used 
to work on Puppy without any problems.

I've got a basic PC (Dell Dimension 4600 running a P4 at 2.66GHz with 2GB

complex app (my stick figure animaton program "Stykz") that loads about 8
libraries has  a few front and back scripts and when it opens it displays a
main window and 4 floating palettes.

The app is built with the Rev 3.5 engine and when I launch it on Windows, it
takes about 5 seconds from initial launch to idle. When I do this on Ubuntu
it is agonizingly slow, taking 25-30 seconds to come to an idle state. And
after this, everything is like molasses - windows take seconds! to redraw,
mouse messages aren't recognized immediately, etc.

I haven't done much on Linux except StackRunner, which was very lightweight,
but my overall question is: are there any "gotchas" I should know about
related to Linux that might account for significantly affecting performance?

I use DropDMG for this. It allows you to add background images,

I think the background has to be an image file.
Very neatly, you can add an alias to the Applications folder to your disk image.


A technique that I use is to make a read-write disk image that way I
want and save it.
Then any time I release a new version, I open the r/w image, copy
across the new app, close the dmg and then use DropDMG to convert it
to a read-only image (which actually creates a new copy rather than
converting the existing one).
This saves a lot of trouble.

one more SQLite GUI - written in Rev...

[viktoras d.]

Dear Colleagues,

well, ok, hmmm, errr [trembling hands], announcing my first public 
release of an application :):


http://ekoinf.net/AA

This adds one more SQLite editor to the plethora of already existing 
ones. This is expected to become a more universal tool, but at the 
moment it is just SQLite frontend. All feedback, critics, bug reports go 
to vikto...@ekoinf.net.


B.t.w. how do I customize dmg image folder? I would like to add some 
explanatory notes like "Drag the AALite icon into Applications folder". 
But I do not know yet how to do this on my mac :-[ ... Will it accept an 
html document as a background (where to put it then?).


All the best,
Viktoras
P.S. changing my own primitive table object to the datagrid is in future 
plans. This is not open source release, however one more application 
will be released just before the e-biosphere event (June 1-3) - and this 
one will be definitely open source.

[OT] where all the databases go...

[viktoras d.]

What does Oracle plan to do with MySQL?
Oracle: MySQL will be an addition to Oracle’s existing suite of database 
products, which already includes Oracle Database 11g, TimesTen, Berkeley 
DB open source database, and the open source transactional storage 
engine, InnoDB.

---
Berkeley DB 
(http://www.oracle.com/technology/products/berkeley-db/index.html) - 
well known and used by Perl programmers. Berkeley DBases can be treated 
as ordinary or associative arrays (hashes) in Perl; previously created 
and maintained by Sleepy Cat Software.

---
TimesTen - in memory SQL database 
http://www.oracle.com/technology/products/timesten/index.html.

Luckily Oracle releases them for free under terms of "Oracle Technology 
Network Developer License", unluckily this prohibits any commercial use 
of the software (need to buy an appropriate license)...

Re: Serialising arrays

[viktoras d.]

Hi Steve,

arrayEncode outputs an array in binary form (for binary storage or 
transfer), not text. When you need to transform array into list do: 
combine myArray using return and tab. After this array myArray becomes a 
list of key-value pairs:

keyvalue
key   value
key   value
...
key   value

Now if you do
split myArray by return and tab
myArray becomes an array again.

this case.


When viewed in a text editor, it looks like:


random characters

Using lineOffSet, I'm finding the first and last lines of the

Any pointers? Is this the best way to save arrays to text?

Re: Can Rev turn text to speech and record it?

[viktoras d.]

just one more idea concerning work flow optimization, 'cause now it 
looks like the vendor wants to be enslaved by machine. What if not the 
server calls the vendor, but the vendor calls the server and listens for 
a report ? I still can not imagine the vendor (if suddenly something 
goes wrong ) being forced to respond to tons of calls per day until the 
problem gets finally fixed. He should be busy with communicating to 
people not the machine. What if the vendor fails to write down an 
important number, how can he get it repeated ? Will the vendor be able 
to respond to midnight calls (e.g. 4.00 AM) and write down everything 
correctly? If the vendor does not respond will server be able to stop 
calling? Will the stopped calling event be postponed or lost?


But if the vendor calls the server a few times per day as he wishes, and 
listens to a report, the situation becomes more humane.


All the best an happy Easter !

Hi, Richard,

I would avoid this esp. if customer has to pay for a call. Many 
customers would disable this feature if it were present because it is 
quite dangerous. It would be more efficient to put a record into a 
centralized database where vendor can collect, see and read all the 
relevant "warnings of the day".

Hi Sadhu,

regarding the autoformat -  hit tab key and this will adjust all

Saving. Hmmm. Did not noticed that except in cases where there are many

Well there is always the associated confusion when faced with new
choices and missing choices where they were once expected, the usual
learning curve, and of course, I'd rather proceed without having to read
all the doco.  Also, disclaimer, I'm not trying to document bugs with
any precision such as 'how to duplicate' etc.  It's just that I have
noticed issues.  So I thought I'd bring it up to see what response was
forthcoming?

Example:  the save doesn't seem to save!  At least, not always.  Eeek,
good thing I kept some backup copies, else I would have lost work.

Example: the auto formatting doesn't work as well as it use to.
There was formerly a choice called format this handler, which fixed all
the identing problems (I often use VI which is such a powerful editor,
but then pasting into Rev could count on the formatting being fixed).
My off-identing is no longer fixed by the editor.

Example: the tool palette, the one on the left with the buttons for
text fields, labels and so forth, seems to go missing.  How to get it
back seems to be inconsistent, sometimes I can choose (something,
different things) on the tools drop down and that does it, sometimes
not.

This is on Windows XP professional.

I bumped into other stuff as well but in this post I'm just sort of
bringing up the general topic - are these well known issues other
people have vocalized and are being looked at, or am I just in need of
instruction or what?

Thanks for listening, 
Sadhu

Re: [even more OT] Talking Heads

[viktoras d.]

but then what is the status of java? There are tons of open source apps 
in java (http://java-source.net/), but a.f.a.i.k. java is not open 
source otherwise IBM wouldn't urge SUN to make it OSS: 
http://news.cnet.com/2100-1007_3-5165427.html. Well, it is 5 years old 
"news".

Richmond, they were probably right.  The essence of open source is that you
have access to the source code and the ability to modify it.  If your stuff
had been written in (say) Python, this would be true, anyone can get Python
on OSS terms and conditions.  Written in Rev, even if you distribute your
source, they have no access to it without agreeing to the non-open source
terms and conditions of the Rev license.  


Probably Richard Gaskin is mistaken for a similar reason in saying that "All
open source applications that run on Windows, Mac, or any other non-FOSS OS
are just as "proprietary" as any Rev project released under similar
license."

No, not really.  If its OSS, you have the source, and you have free access
(not financially, but as in speech) to any tools required.  And indeed to
the source code of those tools.  So you can port it to any OS you like,
including non-free ones. The fact that if so ported it then runs on a
non-free OS however does not say anything about whether the app itself is
free. It is free in virtue of having been written in OSS tools and in virtue
of the fact that users have the OSS rights.

I'm not doctrinaire about the use of non-OSS apps and tools (obviously,
being a Rev licensee!).  Use them all we want.  But it is quite important to
see things for what they are, and it is fair enough, stuff written in Rev
cannot be OSS.  Whether this matters is a different issue.

A while ago I wrote a message to one of the high-ups at Ubuntu offering
to let them have FREE linux versions of a couple of programs I made about
6 years ago about Phonetics using RR.

They were refused on the grounds that, while I was entitled to distribute
standalones free, they were built using proprietary software.

Personally I thought they were being a bit silly.

Re: [OT] Open Source, EULA - the Big Bad Bogeyman

one more "laud" case, not software, but still related:

Listers,

Unfortunately I missed the recent frenzy regarding "Illegal Creativity".

I do not wish to fan that fire here, but do wish to point you to a Landmark
case going on right now involving a very small group of hobbyists, Open
Source Software, and an apparently wealthy individual and his company.

This case has huge implications not only for software developers and
software uses but is rattling around many legal blogs as well. If the
'Illegal Creativity' thread was of interest to you then I highly recommend
following a couple of the links below. If you like David and Goliath you
might also find this interesting :-)

As way of a VERY brief background; a group of model train hobbyists got
together and started an Open Source project written in Java - the Java Model
Railroad Interface (JMRI). Quite a while later KAM Industries came along,
took some of the code, created their own commercial program, patented some
aspects of the program and then started demanding royalties for every
downloaded copy of JMRI.

This eventually ended up in court and in the first instance the ruling was
in favour of KAM Industries. A single individual has mainly represented the
JMRI community and although the ruling was far less than the U$200,000+
sought, the financial impact was beyond this individual's means, even so,
with the help of donations, this individual continued to pursue the case to
a higher appeal court. KAM Industries thus far has spent over U$1,000,000 on
the case.

The result of the Appeal was only last Aug 13th 2008 and reversed the
decision of the lower court. But this is not the end, as of 11 Feb 09 KAM
Industries is seeking damages of U$6,000,000+

You can get a detailed JMRI sided view of the saga here:

http://jmri.sourceforge.net/k/updates.html

Other links pointing to outside perspectives on the implications can be
found here:

http://jmri.sourceforge.net/k/news.html#CAFCruling1

Two I like are the Larry Lessig Blog and Slashdot thread:

Larry Lessig is a Prof. of Law at Stanford, a board member of the Creative
Commons project, and named one of Scientific American's Top 50 Visionaries,
for arguing "against interpretations of copyright that could stifle
innovation and discourse online."

This slashdot thread, make sure you scroll down, discusses EULA's and how
binding they really are.

http://yro.slashdot.org/article.pl?sid=07/08/25/2059231&from=rss

If you are so swayed, you may wish to support this legal battle, the
Donations page is here:

http://jmri.sourceforge.net/k/donations.shtml

Again, I do not wish to re-ignite any recent threads on this List, I post
this here purely as a pointer to Lists, Forums and Blogs much closer to the
coal face and frequented by individuals more qualified to help in such
matters.

Who'd watch TV when you have real life?

Re: silly text editing question

[viktoras d.]

Hi Bob,

I used the following in my table object:
assuming table header (tab delimited list of column names) is stored in 
tabHeader variable


set the itemdelimiter to tab
put (((word 2 of the selectedLine of me) - 1) + \
 the number of items in (char 1 to (word 2 of (the 
selectedchunk of me)) of me)) mod \

 (the number of items in tableHeader) into itemNo
  if itemNo is 0 then
 put the number of items in tableHeader into itemNo
  end if
  answer itemNo

It works correctly as long as cell contents do not exceed cell size. 
Once contents of the cell exceed its size, click on the next cell 
selects text of the previous one and you get the wrong number...


Best wishes
Viktoras

Re: Call for ban (was Re: illegal creativity?)

[viktoras d.]

I started the thread, received all opinions, made my decisions, now 
there is no reason it should continue. As  the one who started now I 
"formally" declare thread "illegal creativity" CLOSED.


Randal replied with intention to give an advice and discuss, and even if 
his opinion is quite different, he did not offend anyone directly, nor 
promoted illegal activity, so a ban wouldn't be fair. No ban, let it be 
peace, please...
