Re: Gaussian pseudo-random numbers -- math issues
Selon Mark Smith [EMAIL PROTECTED]: Timothy, the only way I could find of doing what you want is called 'the polar form of the Box-Muller transformation'. Fortunately, it's not as bad as it sounds. :) I've copied an ADA implementation, and here it is: function polarBoxMuller pLength, pMean, pSdev put false into useLast repeat pLength repeat put ((random(101) - 1) * 0.02) - 1 into x1 -- generate a random number between -1 and +1 put ((random(101) - 1) * 0.02) - 1 into x2 put (x1 * x1) + (x2 * x2) into w if w = 1 then exit repeat end repeat if w 0 then put ln(w) * -2 into w -- rev barfs if w is zero if w 0 then put sqrt(w) / w into w -- ditto put x1 * w into y1 put x2 * w into y2 put pMean + y1 * pSdev comma after tList put pMean + y2 * pSdev comma after tList end repeat return char 1 to -2 of tList end polarBoxMuller This should give you a comma delimited list of (fairly) normally distributed numbers. Best, Mark ps. I enjoy this sort of thing, so thanks for the question!

I'd like to have a few lines of code that produces a sequence of numbers. (whole numbers would probably be okay). I'd like to specify the number of numbers generated. Let's call that Z. I'd like also to specify the desired mean and standard deviation. I'd like the function (is this a function??) to work in such a way that if Z is large, the set of numbers generated, if graphed as a frequency distribution, would be normally distributed, i.e., Gaussian. If Z is rather small, then the mean and standard deviation of the numbers produced will would only approximate the desired mean and standard deviation. Different runs would produce different actual means and standard deviations. If Z is very small, like 3 or 4, the numbers will look almost random. I hope I explained that clearly. Optionally, I might also be able to enter a variable that would specify the desired number of digits to the right of the decimal point. No favors are requested. I'd really be rather uncomfortable with a generous gesture. However, if someone has some code like this sitting around, and you're willing to share it, with a few notes about how to use it, I'd appreciate it. If not, it can't be helped. H... I wonder if some website somewhere would do the work for me. That could work... I looked around, but didn't find anything. Thanks in advance.

Re: OT: take-up of netbooks has been staggering
I think the keyboard size is ok (I can touch type on it). The only thing I think is bad are the trackpad buttons - they're in an uncomfortable place (either side of the trackpad), and they are very stiff. I have to use a mouse with it. From what I've read, it looks like others feel the same way about that. Maybe later versions of the AA1 will sort that out. Mind you, there are going to be so many of these netbooks, so I expect the quality of them to improve still further. I synch everything by Lotus Notes. I run Notes on a couple of Linux servers (linode.com), and under WINE on the AA1 (and on Vista and OS X). People think Notes is just email but it's far more. It's a distributed document database. So I store PDFs, web pages, code, executables, stacks (versioned with annotations), etc. all in Notes. It also means that I have everything replicated in multiple places (my laptops, and a server in Atlanta, and another in California) in case of disaster. I had my development laptop stolen a few years ago, but I only lost a couple of hours of work. But I know Notes is an acquired taste :-) It might be worth looking into using Gmail as a filesystem (using FUSE). I bought the AA1 to do Rev development on, but unfortunately that didn't work out. Maybe others will have better luck with that (could be it will work better on other versions of Linux). If the growth in netbook sales continues, in a year or so I can see there being more Linux laptops sold than Mac laptops. Rev could be very well positioned to take advantage of that. Whilst there are obviously masses of free dev tools for Linux, there is no easy route to visual programming (unlike Applescript or VB).

Background: When the user adds/inserts or updates a record, the current cursor is not up to date anymore and one has to create a new one that reflects these changes And of course it is good style to display the SAME data to the user after that action and not the first record of the new cursor.

Re: making a tooltip (for Japanese)
Nicolas, Go to the Rev Online User space mcgrath3 and look at my sample tooltips stack ToolTip Tricks. It shows many ways to play with tooltips that might help. Tom McGrath III On Oct 23, 2008, at 12:04 AM, Nicolas Cueto wrote: Hello List, I'd like to add a tooltip with Japanese text to objects, and am looking for suggestions on how to script it. My thought is to add a script to an object which uses both mousemove to show a field (i.e.,the tooltip) and send to trigger a hide field after a few seconds. The trigger (which is the card) will also need to put off hiding the field so long as the mouseloc has changed. The challenge for me is how to measure whether the mouse has moved or not. All I can figure out is to add a send command to the trigger-script in the card which'll compare mouselocs both before and after the second send command.

Re: making a tooltip (for Japanese)
Hi Tom, If I click the Run button on the Walkthrough pane of your stack and immediately thereafter click on the Changing Tooltips tab, I get an execution error. I think that Nicolas' problem is that Rev tooltips can't display unicode. He is probably trying to make his own tooltips and therefore needs to check the mouseControl in a mouseMove handler and is also likely to run into focus problems. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering http://economy-x-talk.com http://www.salery.biz Dutch forum: http://runrev.info/rrforum/ Benefit from our inexpensive hosting services.

Re: XML Data Problem
Dave wrote: The following in a string of XML data causes revCreateXMLTree() to return an error: a:DescriptionGorillaz Killers/a:Description Is there a way to handle this? revCreateXMLTree is correct to return an error; is an illegal character in XML. (One of two, the other is .) The 'right' way to handle this is for the XML to be valid; which would be done by either wrapping the offending text in a CDATA section: a:Description![CDATA[Gorillaz Killers]]/a:Description or by using entities in place of the offending characters: a:DescriptionGorillaz amp; Killers/a:Description However, if you don't have control over the XML, and want to parse it anyway, you could try using the dontparseBadData parameter to revCreateXMLTree, to encourage it to do its best. That will probably, but not definitely, let you get away with it - at least for that example. Failing that, if you can't get valid XML, and it's so invalid that revCreateXMLTree won't accept it even when asked to be more tolerant, and you want to parse it anyway, you might have to do some preprocessing to massage out known errors that you want to overlook.

Re: Another DB question
--- Klaus Major [EMAIL PROTECTED] wrote: Hi all, although I did not receive a response to my first DB questions, I dare to ask another question :-) Is it possible to directly search in the data of a db cursor? Or will on have to use a repeat loop through all the data in a cursor to find the desired data? Know what I mean? Background: When the user adds/inserts or updates a record, the current cursor is not up to date anymore and one has to create a new one that reflects these changes And of course it is good style to display the SAME data to the user after that action and not the first record of the new cursor. Regards Klaus Major Hi Klaus, It's a very old problem inherent to the SQL query model with database-independent front-ends: how to ensure that all clients have up-to-date data. And this gets even messier when you're taking transactions into account: changes to the database shouldn't be visible to another user until they have completed and the entire transaction is committed. That's why, in most modern databases, cursors are a 'snapshot' of the records that matched your criteria at the time of query execution. Some databases offer 'live' cursors that will fetch the latest information from the database when you 'move' to a record in the result set. That helps but still leaves you in the cold when you're looking at a record that gets updated by another user while you're idle. Of course, you could use a 'send in x seconds' refresh loop. The way FileMaker Pro and other database-tied front-ends do this, is by pushing update information from the database server to all the clients, based on some sort of publish-subscribe scheme.

If the growth in netbook sales continues, in a year or so I can see there being more Linux laptops sold than Mac laptops. Rev could be very well positioned to take advantage of that. Whilst there are obviously masses of free dev tools for Linux, there is no easy route to visual programming (unlike Applescript or VB). Agreed. Netbooks may well be the killer app to move Linux forward with consumers, esp. in the current economic climate where every dollar counts and the extra cost of a proprietary OS can add as much as 25% or more to the total cost of a cheap computer. I think sometime in the next five years we'll see the dawn of the Golden Age of Linux. I've been lurking on the Gnome UI list for some months now, and I'm impressed with the quality of the discussion there.

Actually there was no live resizing with any window in Mac OS 9. Live resizing appeared with Mac OS X but Rev did not set liveResizing property set to true by default when creating a stack using this system. Richard pointed out this more than five years ago... So, we may hope it will be changed before 2015 :-) In the meantime, as Klaus said, just set it by yourself. Best regards from Paris, Eric Chatonet.

Re: OT: take-up of netbooks has been staggering
It was various issues with the engine and the IDE. Problems with hanging and crashing, memory leaking, the script editor being very slow, the backdrop not working properly (window decorations disappearing until next restart), virtual desktops not working, etc. Maybe some of those issues are related to the plugins I was using. On OS X I've not used any plugins for about a week, and I've not had a single crash (although I've had a couple of lockups that are known bugs). I hope the other issues with Rev are addressed in the next six months to a year. I now have a netbook that's lying idle. The resolution of the laptop was not a problem for me, as I used revNavigator instead of tools like the application browser, and in place of property inspectors. However, as revNavigator might be the thing that was causing the crashes, if I can't use that in future then maybe the resolution would be a problem when working with the normal Rev IDE.

Re: OT: take-up of netbooks has been staggering
I still use my eee 701 quite a bit-- but converted it to WinXP awhile ago. XP runs great on it, but the screen is small at 800 x 480. Using some 3rd party drivers I can scale it to 1024 x 768, but it's a bit hard to read. One of my favorite uses for my eee is to remote control my Mac (always online) via LogMeIn for testing plugins and projects. The screen scaling of LogMeIn is great and allows me to view my MacBook at full resolution. The new eee 901 and 1000 are both 1024 x 600 display. Sadly, the 1000 has the right shift-key so far out of place, it's impossible to touch type w/out actually 'swapping' it with the up arrow key. But, I did see where one could purchase the 1000H (120 Gb Hard drive, Atom processor) for ~ $300 from Ebay using MS Live Search (just go to www.live.com and enter in eee 1000H).

[ANN] and Re: Problem with mask
I have uploaded a sample stack containing 8 different scripts for creating masks and generating oval images. http://www.sanke.org/Software/ThreeMasks.zip. Stack Three Masks demonstrates and lets you compare the approaches of Jim Hurley, Scott Rossi, and my own. All examples use the same basic selelection procedure with a draggable, resizable, and reshapable and already grouped selection graphic (applying the same routines I use for my selection graphic of stack Seamless Tiles 2), which makes it easy to compare the effects of a specific identical size and shape of the selection graphic across the 8 examples. There are three examples based on Jim's script: - The first uses his almost unchanged script, which produced the mask problem with flattened edges on the right and at the bottom. - In the second exampled I have reversed the direction of Jim's within-scan, with the result that now the edges appear on the left and on top Because of the different edge effects I am not sure if the mask problem is caused by a bug in the within-function or could rather be remedied by more precise (?) scan routines. I have tried to change this part of the script in various ways, but without success. Maybe Bernd Niggemann' approach, which I could not yet include here, will show other possibilities. - The workaround-solution of the mask problem in the third example based on Jim's script combines the two examples above. I use a scan in two directions producing two masks with edges at different places. I then combine the two masks, which then results in a perfectly rounded mask without any flattened edges. All oval images produced by the above examples display a slight roughness. Scott Ross's approach, taking a snapshot from the rect of the selection graphic, produces oval images with a very smooth fringe. As my selection tool is already a grouped one, in my minor necessary adaptation of Scott's script the grouping and later ungrouping of the oval graphic was no longer needed, as was also the resetting the templategroup. I am wondering if we could avoid or suppress the flickering that appears when taking the snapshot? In my own 4 examples no masks are created by script. I use prefabricated masks in the form of imported invisible images that are then adapted to the size and shape of the oval selection graphic. Hence, basically only 4 script lines are needed to crop the image and apply the mask. The masks selected as examples are named plain oval, small fringe, wide fringe, and transition.

Re: OT: take-up of netbooks has been staggering
Hi, i can confirm, that the right shift key is really difficult to use. I modified the registry to swap the right shift key with the cursor up key. I just put REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout] @= Scancode Map=hex:00,00,00,00,00,00,00,00,3,00,00,00,\ 36,00,48,E0,\ 48,E0,36,00,\ 00,00,00,00 in a .reg file and imported it. After a restart the cursor up key was/is shift and the right shift is the cursor up key. That´s it.

Hi Wilhelm, Wilhelm Sanke wrote: I am wondering if we could avoid or suppress the flickering that appears when taking the snapshot? just add a 'lock screen' after the mouseUp in the script of Scott's version and the flicker is gone. the beauty of Scott's approach is that he has the alphadata antialiased, which makes for the sharp edges. That from what I understand, this is because he groups the graphic and if you take a snapshot from a group you get antialiased alphadata. I take a simple snapshot of the image and the oval overlaid and get alphadata which is not antialiased, that makes the visible pixels. (at least you dont get the flat sides of the within-approach) For what Jim originally wanted, a masked picture with an oval mask, Scott's solution seems the one, that makes the finest masks. thank you for providing the side by side comparison of the different approaches regards Bernd -- View this message in context: http://www.nabble.com/-ANN--and-Re%3A-Problem-with-mask-tp20139760p20140779.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: OT: 3rd-Party iMovie Titles that Don't Suck?
Judy, I would guess the titles are not pixelating due to iMovie, but probably because of the format you are exporting in? You can get very nice looking titles from iMovie by exporting using this process: http://www.dvcreators.net/how-do-i-export-a-high-quality-movie/ Give that a try and see how your titles look in the exported movie. Also, what is your destination for the movie? Playing in Rev from disc? a web page? On Oct 21, 2008, at 10:20 PM, Judy Perry wrote: Are you serious?!?!? Bummer!

Josh, Thanks, I will try that link. Will get back to you. I export movies for a variety of playback (DVD, YouTube, webpage...). I usually try to use the highest export settings but maybe I just haven't a clue! ;-) Judy On Thu, Oct 23, 2008 at 4:21 PM, Josh Mellicker [EMAIL PROTECTED] wrote: Judy, I would guess the titles are not pixelating due to iMovie, but probably because of the format you are exporting in?

Re: Two DB questions
Klaus, It seems that you come from an old fashioned DB background (i.e., dBaseII, etc) where the idea of a record number meant something. If you read up on the history of SQL, you'll see that one of reasons for SQL was to get rid of the concept of a record number. In fact when you join two or more tables, what would the record number represent since the table that you are returning doesn't actually exist in the database (it's created on the fly). However, there IS a way that Revolution is particularly good at: Return your records as a list (as opposed to a record set) and then go to the line number (which becomes the record number) and use items to get at the various fields. As long as your returned data isn't too large, it should be very fast. As to your second question (how do you know if a table has any data in it), I've always used SQL to give me that answer: SELECT COUNT(*) FROM mytable Any SQL database worthy of the name should have at least this aggregate function. PostgreSQL at least, doesn't require the GROUP BY clause with COUNT(*) and I suspect others would be the same. If the record count is 0, there hasn't been any data entered. It won't choke if there are no tables since in this case, zero is a valid answer. len morgan ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Bernard, This is off topic to this topic but I'm just catching up on a 100 odd List posts and was reading your drama regarding crashing Rev, and having been in a similar situation where mine kept crashing but everyone else's worked happily I too agree with those that there is something with 'your peculiar situation' which is the cause of the problem. Not necessarily Rev, the OS, plug-ins, but a combination of the lot. So the fact that you have stacks going into and out of Notes strikes me as peculiar. Does Notes compress and uncompress? Is it UTF-8 or UTF-16? What about encryption? Is there any possibility that the process of inputting and outputting stack files changes just one character within the stack file and that this then has a fatal effect on Rev? Maybe numToChar(29) or numToChar(30) and Notes produces results that upsets certain Rev plug-ins? Glad to see you are enjoying some stability on OSX at the moment.

Re: [ANN] and Re: Problem with mask
Recently, Wilhelm Sanke wrote: Scott Ross's approach, taking a snapshot from the rect of the selection graphic, produces oval images with a very smooth fringe. As my selection tool is already a grouped one, in my minor necessary adaptation of Scott's script the grouping and later ungrouping of the oval graphic was no longer needed, as was also the resetting the templategroup. I am wondering if we could avoid or suppress the flickering that appears when taking the snapshot? Yes, there are probably a couple of ways to eliminate the visible selection/creation of the mask (which is surprisingly more trouble than expected), but the intention of this stack to was to demonstrate the process for Jim Hurley. This was not intended to be a finished tool/library for developers. I believed it would be more informative for Jim to see what was was happening rather than keeping process hidden.
