Most Efficient Timer?
I've been thinking about timers recently and thought I run this by the list to see what other Rev experts thought. I guess the way to set this is up is: Can you script a more efficient timer? -- The way I usually build asynchronous timers uses a send in structure like the following: (simplified for example) local tCurrTime on runTimer if not the uAllowTimer of me then exit runTimer if (the millisecs tCurrTime + 1000) then put the millisecs into tCurrTime put the long time into fld 1 end if send runTimer to me in 100 millisecs end runTimer The above example checks the value of the milliseconds 10 times a second and puts the result into a locked field after one second has elapsed. But it also generates 10 messages a second, and it occurred to me that another way to do this is to use the wait x with messages construct which I'm guessing evaluates time many more times a second, but at a lower level than send in: local tCurrTime on runTimer repeat forever if not the uAllowTimer of me then exit runTimer wait until (the millisecs tCurrTime + 1000) or \ (not the uAllowTimer of me) with messages put the millisecs into tCurrTime put the long time into fld 1 end repeat end runTimer Both of the above routines provide the same output. However, when viewing the %CPU use on a Mac OSX system with the Activity Monitor, CPU usage is clearly dependent on the frequency of the send in message: with 100 milliseconds frequency, the first handler runs at about 15% usage, and with 50 milliseconds frequency runs at about 30% usage (makes sense). Amazingly, the wait x with messages handler runs at less than 1% usage. And because with messages does not block other messages from being sent, this seems a very efficient way to run a timer. Obviously the above is useful only in situations requiring accuracy of 1 second or less, but at first glance I can't see any drawback to using this method. Can you?

Increasing the frequency increases the chance of getting it right (but doesn't guarantee it). One uncertainty about the wait condition with messages is that it isn't documented how frequently the condition is evaluated. I was told once that wait ... with messages was inefficient because it was constantly evaluating the condition. However, this doesn't seem to be the case. From some simple testing (calling a function in the condition), I find that the time between evaluations varies, ranging from about 5 to 256 milliseconds (when no other activity is taking place). So for 1-second accuracy, I don't see any drawbacks. Cheers Dave ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Is Windows a Virus? No, Windows is not a virus. Here's what viruses do: They replicate quickly - okay, Windows does that. Viruses use up valuable system resources, slowing down the system as they do so - okay, Windows does that. Viruses will, from time to time, trash your hard disk - okay, Windows does that too. Viruses are usually carried, unknown to the user, along with valuable programs and systems. Sigh... Windows does that, too. Viruses will occasionally make the user suspect their system is too slow (see 2) and the user will buy new hardware. Yup, that's with Windows, too. Until now it seems Windows is a virus but there are fundamental differences:Viruses are well supported by their authors, are running on most systems, their program code is fast, compact and efficient and they tend to become more sophisticated as they mature.

The one that hogs the system is when you wait for a system condition to change: wait until the mouse is up, repeat while the mouse is down, that sort of thing. Even then it's okay if you're actually _doing_ something. The problem enters in when you have something like repeat while the mouse is down set the loc of me to the mouseLoc end repeat The problem here is that as fast as the system is able you're setting the loc of the object to the exact same value (because most of the time the mouse isn't moving). Specifically, there is nothing wrong with wait 55 ticks with messages. Further, you will still see a responsive system with wait 0 ticks with messages. In that video game I programmed a year back, I have a delay loop to keep the game from running too fast on very fast systems. It keeps track of how long it needs to wait to update the screen. On slower systems, that value can decrease to 0, or even -1 or -3, so the code executed is wait -3 ticks with messages It still works. regards, Geoff Canyon [EMAIL PROTECTED] ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

Re: barcode scanner
In many cases this is true. But think about the case where you are scanning identical items. It would nice to be able to type 10 and then scan the item instead of scanning each identical item. Suppose you want to route the item somewhere. You need to be able to enter the routing information. How about using a scanner to log in? You would probably want to type a password. If you just want to scan an item and then go to the next item and scan it, then not being able to tell where the input is from is fine. But in all the other cases you probably just want the scanned information going to a specific field (container) and it would be nice not to have to force the focus to that field with an addition mouseclick or tab(s) etc. Michael On Nov 27, 2004, at 10:48 AM, Frank D.

Amazingly, the wait x with messages handler runs at less than 1% usage. And because with messages does not block other messages from being sent, this seems a very efficient way to run a timer. Obviously the above is useful only in situations requiring accuracy of 1 second or less, but at first glance I can't see any drawback to using this method. Can you? None that I can see, but I managed to get myself confused on the issue: if you only want a time sent once a second, why not just send it in 1 second rather than polling several times a second? I guess Scott was concerned about the smoothness of the time display ticking over. If you send every 1 second, and there is something holding up message processing, the timer may be late to update. Increasing the frequency increases the chance of getting it right (but doesn't guarantee it). Wouldn't any issues that would delay the firing of a one-second timer also delay a 1/10th second timer as well? Anything that's going to stop a 1 second message is also going to stop a 1/10 second message as well. It's possible I suppose for send...in to take slightly longer than a second, so when a visible display is ticking over I generally use something like 55 ticks, which should (virtually) guarantee that it will tick over. My brain's hurting thinking about this. But if you send in 55 ticks, there's a good chance you won't have hit the next second when the message is handled, and so the timer display won't update until the next time through. So you're likely to get a visibly uneven update. If you send in 1 second, it's probably going a fraction more than I second between the send and the point where the display is updated. Eventually, you're going to see a 2 second jump in the display. wait...with messages is perfectly fine to use. The one that hogs the system is when you wait for a system condition to change: wait until the mouse is up, repeat while the mouse is down, that sort of thing. Even then it's okay if you're actually _doing_ something. The problem enters in when you have something like The repeat until the mouse is down problem I can understand. But I need more convincing about wait. wait until (x + y 1000) with messages -- assume x y are script locals or globals wait until the mouse is up with messages wait until myFunction() with messages -- assume myFunction returns true or false Won't the frequency at which the conditional is evaluated be the same? If it gets evaluated as soon as nothing else is happening, then you'd expect all three to be processor intensive. But it doesn't seem to happen that way. On the other hand, I can't see what determines the frequency either. Cheers Dave ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
Re: barcode scanner
In that case it would likely depend on the scanner and on the interface between the scanner and the computer. In some cases this might not be possible to distinguish, in others it may depend on the configuration of the scanner, and in others it might require an external for Rev. Since the barcodes rarely use letters other than a possible 'X' (ISBN #s), one workaround might be to create a 'simulated' numeric keypad on the letter keys, then trap these and handle them specially for your purposes (with a keyDown handler); for example: Y=7 U=8 I=9 H=4 J=5 K=6 N=1 M=2 ,=1 space=0 Not a very elegant solution, but it could be made to work, and would rarely if ever interfere with a barcode scanner.

It would nice to be able to type 10 and then scan the item instead of scanning each identical item. Suppose you want to route the item somewhere. You need to be able to enter the routing information. How about using a scanner to log in? You would probably want to type a password. If you just want to scan an item and then go to the next item and scan it, then not being able to tell where the input is from is fine. But in all the other cases you probably just want the scanned information going to a specific field (container) and it would be nice not to have to force the focus to that field with an addition mouseclick or tab(s) etc. Michael On Nov 27, 2004, at 10:48 AM, Frank D.

Roger, Actually you can set the linesize of the line or polygon tool; you can have both your arrow and line size. What you need apparently is more intermediate points in order to control rate of drawing between end points. One way to do this would be with, you guessed it, Turtle Graphics. (You would want the version that does vector graphics, not bit map.) For example, you could control the motion between any two points A and B as follows: on mouseUP put 0,0 into A put 300,300 into B startTurtle setXY A setheading direction(B) put distance(B) into d put 3 into s --Or whatever works for you repeat round(d/s) times forward s --Perhaps a wait here end repeat setxy B --Just to take care of the rounding error end mouseUP And you could iterate this to take you through a sequence of points.

One approach to making a timer more efficient is to minimize when the field is updated. It takes about 1.5 ms to update a field. It takes 1.7 ms to update a field and then unlock the screen. Here are some ideas: Only update a field if the new value is not the same as the previous. Calculate the delay each time to make the next scheduled time at 100 ms after the second. Do not update if the number of pending messages is greater than some amount. Even though it might take more time, you might want to experiment with unlocking the screen after an update.

However, taking a look at the CPU usage shows this simple routine runs around 14% to 15% or so processor usage. The wait x with messages apparently uses next to nothing. So while efficient script-wise, send in appears to require significant more engine power to run. That's my take on this anyway without knowing the details about Rev's inner workings. You may say what's the big deal about 15% CPU usage? It may not be an issue for many folks. In my case, it is a big deal: moving images around a card, swapping the icons of buttons, scrolling text in fields, all this stuff adds up and places higher demands on the engine. Anything I can do to reduce these demands enhances the ability of my apps to play nice with others. FWIW, I've come across other things that contribute to CPU use. From the above, running a timer and updating the time in an unlocked field requires about 4 to 5 times as much usage as when placing text in a locked field. Locking the screen before updating a number on on-screen items can place very high demands on CPU usage if done frequently. You may recall the jukebox project I posted some time ago -- I consistently ran into memory problems when trying to move all those bubbles around the screen. I tried everything I could of the get the processor use down and on a whim tried removing the lock screen instructions from my scripts. Not only did processor use become manageable but Rev was fast enough to update the 25 or so images without major delay. This may not work for all situations but it's a good trick to keep in mind.

To get started, use this simplified syntax for the password method. (The key method is less suited to those new to this.) encrypt source using cipher with [ password ] pass_phrase [ at bits bit ] where that in brackets is optional and the x symbols are expressions. This can be simplified to this: encrypt source using cipher with pass_phrase I plan to suggest a default cipher. If that idea is adopted, then the command will simplify more. If there is an error, 'result()' returns non-empty. The encrypted value is in the variable 'it'. It will be larger than source. Use bf-cbc to start for the cipher value. To find other ciphers to try, use cipherNames()--except on OS X for now. A current weakness is that the default salt value is empty, which will make the encryption slightly weaker. This will probably be fixed soon. For most people, procedures in using encryption have greater weaknesses than this, so I wouldn't worry about it (for now). (Here is how you crack a cipher with a Cray: You call up the company and ask for the head engineer and offer him a Cray for the keys.)

Tabs navigation Script for windows!
Hi everyone, Hope you had the great monday I had! So here's ma fonkee email for nofemba 2004! Because Im in a great mood, I've restored all my links on Monsieurx and here's my gracious contribution to help out the poor of us windoze boxes users, work smooth and smooth as we usually like to... If anyone can point me out to the mac and linux way of things, shortcut wise regarding these keys, I'd really appreciate it for an improved tip... And there's a Nitrous plugin coming to exploit this in all its variations too! This weekend probably... Why this script? In moft windows, control-Tab (and control-Shift-tab) allow you to navigate across different tabs in a tab pane in any application - except, you guessed it, RunRev! Control-Tab hides the palettes while on the mac control-alt-tab does - funny too, the tools menu hints at control-t which doesn't always work! This is already is a bugzilla suggestion. Relax! So pending N. Dayakar's email, and RunRev's network upgrade, my impatience and fortuite skills, I told myself this should be trivial right? well, it wasn't rawkeyup... it wasn't set the selectedline of btn thetabs , it wasn't set the hilitedline (or text) of btn thebats (for the trivia, it wont work either, it's for fields only)... The right command was select line 2 of btn thetabs in a rawkeydown! Newbies, behold, even an expert tries it all! Scripting an english language like conversation with the computer would imply a minimum of english language intelligence right? Go figure... Rant? No, a long awaited XOS feature I want and getting closer each day! But I go for the tabs right now... Here's your script N! You'll have to adapt it to your button's name naturally... It was implemented as is and tested into the new ControlsBrowser plugin soon available at MonsieurX.com (some irrelevant parts of the script were removed to prevent confusion). Sweet scripting dreams Xavier http://monsieurx.com RunRev Nitrous Plugins -- The following script should be inserted into a card script (first in the line of events so that a card tabbed button will respond, If you have multiple tabs, look at the focus functions in the revdocs to adapt it...

Re: Most Efficient Timer?
With send times that short, I would not be too worried about most of those readings. The 2% usage for a 1 second timing is a bit more meaningful, and even this is not too bad (though I suspect it could be better). Bear in mind that if running these tests in the dev environment, some of that percentage will be due to added overhead of the development environment. You should likely test this with standalone apps to get a more meaningful measurement. On a 500MHz G4 (OS 10.3.6), I created a new mainstack with a single checkbox. The checkbox script is: on x send x to me in 1 second set the hilite of me to not the hilite of me end x And the mainstack script: on openStack send x to button Check in 1 second end openStack I then saved this and saved it as a standalone. Activity monitor (updating every 2 sec) reports: The Rev IDE with the stack open (and no others): keeps shifting between 0.5%, 1%, 1.9%, 2%... The standalone app: about the same, except that it occasionally drops as low as 0.4%, and I did see *one* flash of 3%. Now changing the update interval to 0.5 sec: CPU usage actually flashes from *zero* to as high as nearly 5%. Now changing the update interval to 5 sec: CPU usage switches from zero to about 1.9 or 2 percent. Hint: most of the time (CPU perspective) the usage is zero. When updating the checkbox, the usage can jump to as high as nearly 5% for a brief period of time. My guess is that the activity monitor is biased toward giving the higher readings. I used the command-line 'time' utility to measure the runtime of the standalone. The results after a few seconds were: real0m14.617s user0m0.890s sys 0m0.230s Combining user with system CPU time of the process yields about 1.12 seconds, out of 14.617 seconds that the process was running. This would suggest about 7.7% CPU usage. Bear in mind that this includes startup time, displaying the window, initializing the engine, etc. Now after a somewhat longer run: real1m6.203s user0m1.200s sys 0m0.350s This suggests usage of 1.55 second over the course of 66.203 seconds, for about 2.34% CPU usage. Notice that this is much lower, and this is likely due to the fact that much of the startup time, etc. from the runs is a one-time issue. Next experiment: I created a new mainstack and saved it, then saved it as a standalone (no objects or scripts). Now I run the 'time' command on this standalone: real0m47.594s user0m0.530s sys 0m0.250s This would be 0.78 second over 47.594 seconds, or 1.64% CPU usage -- with *NO OBJECTS OR SCRIPTS*. This time is likely taken up by the Rev engine, so it would seem that the actual CPU usage of my little checkbox mechanism is only about 2.34 - 1.64 = 0.7% CPU usage. Hmm You can't always judge a book by its cover. Do note that these percentages will likely decrease slightly with longer runtimes (flattening out because of startup time, initialization, etc.), but I have no reason to run the tests for that long, I think I made my point here.

On the runrev.com website you cn find the differences
between Dreamcard and the other Revolution editions :
http://www.runrev.com/section/platform.php
When I opened the documentation to find more
information for the 'encrypt' command, I noticed at
the bottom of the text that it is part of the SSL
Encryption library
So it could be that 'encrypt' doesn't work inside
Dreamcard --
Definitely the case - on http://revolution.runrev.com/section/whats_new.php
it says
Industrial strength encryption
Encrypt and decrypt data for all commerce and secure applications using
industrial strength encryption (Revolution only).
so it's pretty clear that it would not be supported in Dreamcard (and
certainly it never returns any value for me, in Dreamcard).
however, you can sue a simple 'compress'
/ 'decompress' pair as a subsitute codec :
--
put compress(field password) into \
URL binfile:password.bin
--
put decompress(URL binfile:password.bin) into \
field password
Or, since you never need to retrieve the password, but merely ensure that
it has been reproduced
put binarydecode(H32, md5Digest(field password my secret string),
myVar)
put myVar into URL file:password.hex
and subsequently
put URL file:password.hex into correctValue
put binarydecode(H32, md5Digest(field password my secret string),
myVar)
if myVar correctValue then
password is wrong ...
end if
It's always a good idea to include an md5digest in
your file to make sure nobody has tinkered it.
Yep. I'd go with that too, just to be extra sure no-one has tinkered with
it improperly.
BTW - if you are using Dreamcard, do you plan to distribute the stack with
the player ?
Dreamcard won't allow you to build standalones. If you distribute the
stack, you'll need to be careful about password protecting the stack - raw
stacks can be easily read in any text editor which could make your
password mechanism too clear to the enterprising student.

I can give my opinion that might hold you until you get an authoritative answer. 1. There are some optional portions. In most cases they can be simply left empty, but in some cases you need a flat of some sort. So you might have a seven arg function like this: function encrypt source, cipher, usePassword, passOrkeyVal, useSalt, saltOrIV, bits 2. The other reason is error handling. The only option for a function is throwing an error. (See try and throw in the Transcript Dictionary.) The error in 'result()' and the data in 'it' are used other places, so for many these are not new concepts.

Suppose I have a stack file with some reusable functions and constants in it - e.g. for doing math How do I store the constants in my reusable stack and then make them available to the rest of the app when I load the stack? If I have some functions, how do I do the same kind of thing with them? I am still not clear on the use of 'insert script' or custom properties. If somebody could show me how this works with the following constant and function, I would be very grateful e.g. my library stack contains ... a constant called 'HalfCircle' with a value of 180.0 a function called 'degreestoradians' defined as function degreestoradians degrees return (degrees/180.0) * 3.1415926 end function How do I store these in my library stack? How do make them available to the rest of my app when the library stack is loaded?

Re: QT-MP3?
Hello Richard, In beetwin possible others ways, To test the procedure : 1.- Drag'n drop the movie (demux files only) over iTunes. 2.- Export the file as MP3 from the iTunes Advanced menu. To drive it from within Rev : 3.- Build the automation process in driving it trought applescript or QuickKeysX from within Rev.

AirTunes and REV
Has anyone figured out how to send to an Airport Express with AirTunes? I know that the music is wrapped in Apples new compression scheme and then decoded. Also, Dolby files are wrapped and then unwrapped and then decoded at the stereo. SOOOo if REV could pass to the airport express and do the wrapping then this would be easy.

How do make them available to the rest of my app when the library stack is loaded? You can't store re-usable constants :-( Constants have to be declared in every script that uses them. The easiest way to to make them functions rather than constants. Make your stack with the stack script containing all your math functions e.g. function halfCircle return 180 end halfCircle function degreestoradians degrees return (degrees/180.0) * 3.1415926 end function When you need to access these functions in another stack file, go to the Inspector for that client stack and set the Stack files to include your Math stack. This will make sure that the file containing your Math stack is included in any build. In the startup routines i.e. preOpenStack or openStack, include a line saying: start using stack Math Now you can call your halfCircle or degreestoradians functions from anywhere in the client stack or it's sub-stacks. There are other ways to achieve the same result, but this is the one I use most of the time.

Streaming tunes through Airport Express with AirTunes is a snap. It powered my gal's birthday party a couple months back. Good times. But doing it from Rev may be less of a snap. That is, unless Trevor has more goodies in store in his externals collection. :) In the meantime, could you let iTunes be the engine and drive it with Rev via AppleScript? -- Richard Gaskin Fourth World Media Corporation ___ [EMAIL PROTECTED] http://www.FourthWorld.com ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
Reusable Code (again)
Sorry, I meant to ask for a variable example, not a constant. My question is this then ... How do I have my reusable stack introduce a global variable that can be passed around in an application that uses the stack? Can I declare a global variable in the stack script of the reusable stack and then use the 'start using' construct that was described earlier? Does this avoid having to declare the same global variable in the rest of my app? Best Gordon e.g. my library stack contains ... a constant called 'HalfCircle' with a value of 180.0 a function called 'degreestoradians' defined as function degreestoradians degrees return (degrees/180.0) * 3.1415926 end function How do I store these in my library stack?

Re: Reusable Code (again)
No, it doesn't really work with either globals or constants, although again, you can fake it with handlers. Suppose you have a global in the Math stack called gVar. You can set it from anywhere using a special handler in the Math stack script: on setGlobal newSetting global gVar put newSetting into gVar end setGlobal And then retrive the value at any time: function readGlobal global gVar return gVar end readGlobal Using the do command, you could make these general global setting reading handlers but for starters, it's easier to follow this way. This is a way to get around having to declare the global in every script where you need it.

stacks interacting over LAN? (newbie)

Well this might be a little too involved but one solution might be: qt-WAV/AIFF-mp3 You could use the EnhancedQT external to convert to a temporary wave/aiff file. Then send that file to something like the lame http://sourceforge.net/projects/lame/ mp3 encoder executable using the command line. The lame executable isn't too big and could be hidden in the app bundle on OS X I think. The EnhancedQT external currently only supports exporting using a dialog but adding an option to just export and audio track to a high quality WAV/AIFF without any additional options wouldn't be too difficult. -- Trevor DeVore Blue Mango Multimedia [EMAIL PROTECTED] ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
