Re: Newbie question re fields -- javascript
Dave - as with shell, do does a line - that is if you were to look at
the string you create with:
put alert (' myScore ');
it would span several lines. Imagine typing that into the script editor - it
would make no sense right? So you need to have the LiveCode as a single line
and not split over multiple lines like this. That is not to say the
Javascript / AppleScript etc has to be one line - so simply construct
multiline JavaScript that would work in an HTML file, get LiveCode to
produce this JavaScript and put it into a variable, then do the contents
of the variable in the browser.

Re: [OT] legality of DVD backup
In most countries this is what you would call legally defensible under faire use or the equivalent in your jurisdiction. There is no case I know of where someone has been prosecuted for copyright infringement by making a backup copy for personal use, given that they own a legal copy in another medium. However there is nothing to stop a copyright holder taking you to court, in which case it would be down to you to make a faire use or equivalent defence - and you could then have the privilege of being (as far as I know), the first person to loose such a case :) In the real world, you are extremely unlikely to be taken to court over this issue, as the industry has plenty to do taking clear cut cases of downloading pirated DVD's to court, and the last thing they want is to loose a faire use case and so set a precedent. A related issue is the obtaining and use of the software to actually do the decryption (which is why it can be hard to get a copy from a mainstream site - as Macrovision does its best to take action against distributers). A good account here is taken from the wikipedia articlehttp://en.wikipedia.org/wiki/DVD_Decrypter : Under United States' Federal law, making a backup copy of a DVD-Videohttp://en.wikipedia.org/wiki/DVD-Videoor an audio CD http://en.wikipedia.org/wiki/Red_Book_%28audio_CD_standard%29 by a consumer is legal under fair use http://en.wikipedia.org/wiki/Fair_useprotection. However, this provision of United States law conflicts with the Digital Millennium Copyright Acthttp://en.wikipedia.org/wiki/Digital_Millennium_Copyright_Actprohibition of so-called circumvention measures of copy protections http://en.wikipedia.org/wiki/Copy_protection. In the noted 321 case, Federal District Judge Susan Illston of the Northern District of Californiahttp://en.wikipedia.org/wiki/United_States_District_Court_for_the_Northern_District_of_California ,[5] http://en.wikipedia.org/wiki/DVD_Decrypter#cite_note-4 ruled that the backup copies made with software such as DVD Decrypter are in fact legal but that distribution of the software used to make them is illegal. As of the date of this revision, neither the US Supreme Courthttp://en.wikipedia.org/wiki/US_Supreme_Courtnor the US Congress http://en.wikipedia.org/wiki/US_Congress has taken definitive action on the matter.

Re: [OT] legality of DVD backup
Here is a good link for Faire Use - http://centerforsocialmedia.org/fair-use Oh - and another probably more important point which has nothing to do with the copying - is the issue of public broadcast, so while you can watch a DVD with friends at home, in a school is another matter - which is why a lot of schools will have licences explicitly taken out for this. For some reason I've never quite understood copyright lawyers seem to have it in for screenings in prisons for instance. Again the faire use issue comes in - if it is entertainment then there is no faire use defence, but if it is used for critical comment and analysis in an education setting, then there is more of a case Here is an example of the sort of generally accepted exemption within schools and colleges in the USA: - taken from this sitehttp://www.albion.edu/campusprograms/event-scheduling-and-program-policies/movie-viewing : *Face-to-face Exemption* Many of you may know that there is an exception to the public performance fees for college and universities. That exception is only in the case of face-to-face classroom instruction by a faculty member. The faculty member may show the film/movie outside the normal class period (at night for example), however, it is only for those students who are registered for the class. The movie must also be shown in spaces that are designated for instruction; therefore library screening rooms, residence hall or student union lounges, cafeterias do not qualify. A faculty member cannot show it for his/her class and then open it up to the rest of the campus. In order to invite others, the public viewing rights must be purchased. Acceptable attendance for films in which the copyright is not purchased only include students registered for the class, the instructor and guest lecturer(s).

OT: Invitation to some groovy LiveCode based co-learning!
Anyone out there interested in learning how to build upon their Rev ? LiveCode experience and learn how to integrate this with modern web frameworks? I'm taking the plunge, and have forked out silly amounts of money to buy a bunch of books, and think that there may be some other people on the list that would be interested in learning this stuff too? It will be a lot more fun in a group of a few of us - and well that's a lot more Live coding style isn't it :) I'm proposing taking a subject that I know very little about, learning a few steps and making some quick videos and LiveCode based example code, available each week, and supporting this with the option to take part in a Live Coding event via small live video conferencing. The live events will be limited to no more than 20 people. As a starting subject, I'm going to take a look at something which will be both useful to the community as a tool, and a little geeky so that well to be honest we don;t get too many people wanting to do it while we iron out the kinks on how to do this properly. *Groovy* The topic is going to be integrating LiveCode with Ruby on Rails like frameworks. To be even more geeky, I'm choosing the Java based version of Rails - Grails http://en.wikipedia.org/wiki/Grails_%28framework%29, which in turn is based on Groovy. We'll learn how to use LiveCode to script the command line tools that come with these frameworks and mix and match LiveCode front ends, and even server side code written in LiveCode. Anyone interested in accompanying me on my journey to learn more about these modern web frameworks and how they use object relational mapping, MVC, closures, naming conventions, and all sorts of other goodies (like integrating LiveCode with Java - Jan are you out there :) - feel free to join in. *What we will make* The practical part of the project is going to be to build an online database of open source handlers using these modern tools. That is we will get up a quick and dirty web site that is based on the LiveCode object model we are all familiar with - stacks, cards, groups and so forth to create a search-able repository of open source handlers. Grails, will allow us to create simple web services, around this database, one in which we can ad all sorts of cool things like folksonomy tagging, dependency graphing and the like. We'll start simple, frankly we will have to because this is not my field at all - but will I think end up with a useful community service and a shed load of groovy learning. *No teachers, no guarantees. We are all in this together!* So this is not going to be a course in any traditional sense. The aim is we learn from each other, in a bit more of a visual and fun way than we can do on an email list. I'm going to experiment with a number of features including live screen casting, that make this possible, but that won't be an essential part of the gig. That is turning up for the live events - is going to be an optional but fun part of the experience.

An easy way to pipe input into shell commands?
Is there a neat way to pipe input into shell commands from STDIN? The usual way I do it is to recreate everything as temporary files and then pass the file references - however it is both a hassle and can leave clutter around although I assume files stored in the tempname directory get cleared out properly on all platforms (anyone - I've not tested this cross-platform?). For smaller inputs (one liners) - you can construct a shell command which pipes an echo command - like this: put echo 'Hello world!' | commandLineThatTakesSTDIN into someShell put shell (someShell) But is you have a lot of text in a variable, that you want to pipe to a shell command this is not going to work - hence the need to write out to a temporary file. I'm just wandering if there is a way to do something like set the contents of STDIN from LiveCode, then just enter the shell command, or if this could be some form of feature request? ___ 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
Getting line endings straight.
Most of the time we don;t need to worry about line endings - Rev handles them for us transparently. However, sometimes when workign with external sources you can get bitten. I thought I'd post this to make sure I've got things straight, and hopefully clarify things for others. My understanding is as follows: 1. LiveCode uses the unix flavoured line ending character internally. That is LF or numtochar(10) in LiveCode 2. LiveCode translates text for you in the background when you use file url's, and open driver, open file, or open processcommands in text mode. For example when you use the normal file url syntax - ie put someText into url 'file:some.txt' 3. On OSX and Linux this is the same as LiveCode's internal line ending char = LF or numtochar(10) 4. On Windows LiveCode would translate the line endings to CRLF = numtochar(13) numtochar(10) 5. On older Mac Classic systems the line ending character is CR = numtochar(13) Some gotcha's: - A carriage return is numtochar(13) - however LiveCode internally thinks that CR = LF = numtochar(10) - On OSX LiveCode does not write out text using the systems native line endings - it uses the older Mac Classic line endings (presumably for easier compatability)! The last one I did not know. Personally I think it is bad behavior, though most OSX applications handle either form of text file absolutely fine - some command line tools expect the native unix style line endings (LF). If you want to use these tools - don't use file - for writing out text - use binfile. You can test this on your OSX system using the following in the message box: put Hello CR World into someText put the tempname .txt into someFile put someText into url (file: someFile) put url (binfile: someFile) contains numtochar(10) Have I got something wrong here - or should we really be asking RunRev to make it easy for us to read and write text files in native LF mode? Perhaps there should be an IDE property which we could set base on the platform, or perhaps they can tweek their background translation code to keep backward compatibility, while giving us native line endings on OSX? ___ 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
Database: INSERTS, speed and primary keys
I've spent the weekend refreshing on databases. I'm using LiveCode and also Trevor's fabulous sqlYoga, and beginning to realise how little I know about databases! The question I've got is about the database schema design and optimising it for the speed of adding records. * Exporting Handlers* I think I may be missing some basic things, as it seems to me that the only easy way to force an update to be unique is to use primary keys. You can use triggers but this seems like this would be slower. However if I uses a surrogate primary key (ie the usual auto-incremented numeric id field), for each updated record I need to check first whether it is already in the database before adding it - this is a lot of overhead in terms of finding the ids based on other fields. However I ran in to problems using composite primary keys, as the queries got a too complicated for me to track down the bugs in them easily. To elaborate on the example - in LiveCode each and every handler in the LiveCode environment can be uniquely identified by the following fields: 1. handler_name 2. handler_type (ie one of c,f,g,s standing for command, function, getprop, setprop) 3. location (the rugged id of the LiveCode control - ie control id 1387 of card id 1002 of stack Test) 4. hander_num (not usually useful - but there can be more than one identical handler in a script, only 1 is ever called) 5. handler_scope (p for private for example) From these elements you can define a unique reference to a given handler in script with the following type of key - test_Command,c,stack Test,1,p Which would refer to (the firsts instance of) a private command test_Command in script of the the stack Test. I've been using this way to refer to handlers for years and have a large library of code that manipulates references to handlers, ie: - hkey_EditScript hKey - put hkey_GetHandler (hKey ) into somehandler - put hkey_ExtractHandlerCalls (hKey ) into hKey s Therefore in database terminology hKey is a composite primary key, and you can make this a composite primary key. This has the advantage of enforcing that addition of keys to the database is normalized - that is adding an hKey that already exists fails to add a duplicate entry. The problem I am having is that while using a composite primary key is great for making the updates fast and simple - it is giving me headaches with the more complex joins and queries, I'm building in LiveCode / sqlYoga. However I do need these updates to be as fast as possible - a few ticks for adding several hundred records, as I want to automatically add them to the database every time a script is compiled. These are the options I can think of: 1. Stick to composite primary keys for the handler table, and battle through all the bugs / issues with using complex joins based on composite keys. 2. Use triggers - and unknown to me, not tested with regard to speed, and looks like it may be difficult to keep sqlite and online db in sync, as they may not share the same way of implementing triggers. 3. Use a staging table of some sort - use composite primary keys on this temporary table, and then at a later date (perhaps when the stack is saved) process this temporary table, moving the data into the db proper. 4. Asynchronously update the db - perhaps using a slave process, to maintain GUI responsiveness. 5. Something else? At the moment I am going for 3, as it seems to offer the best in terms of keeping the db design as conventional as possible, and speed in terms of GUI response. Any advice from the db experts out there? ___ 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

The issue is preventing adding of duplicate records. I want to prevent adding the same hKey, say: test_Command | c | stack Test | 1 to the database. Using INSERT with the primary key set to the autoincrement id field, you would get records like this: *id | name | type | location | hnum* 1 | test_Command| c | stack Test | 1 2 | test_Command| c | stack Test | 1 3 | another_Command | c | stack Test | 1 4 | another_Command | c | stack Test | 1 Only by making the primary key = name,type,location,hnum instead of id woudl you get a fast normalisation of the data inserted. ___ 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: Database: INSERTS, speed and primary keys
OK - not getting very far with that - Google is not my friend :)
Can you give me an idea of what the CREATE statement would look like?
CREATE TABLE 'handler' (
'name' VARCHAR(255) NOT NULL,
'type' VARCHAR(255) NOT NULL,
'location' VARCHAR(255) NOT NULL,
'handler_num' INTEGER NOT NULL,
PRIMARY KEY ('name', 'type', 'location', 'handler_num')
);
With a surrogate key:
CREATE TABLE 'handler' (
'id' INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
'name' VARCHAR(255) NOT NULL,
'type' VARCHAR(255) NOT NULL,
'location' VARCHAR(255) NOT NULL,
'handler_num' INTEGER NOT NULL,
);
So how do I create a secondary key from name,type,location,handler_num and
make sure that these combined columns are unique?

Only by making the primary key = name,type,location,hnum instead of

woudl you get a fast normalisation of the data inserted.
You can create an secondary key for those fields and still use your primary
key auto-increment field for a foreign key in other tables.

Deployment issues: sqlite?
I'm interested in the experience of people deploying Rev / LiveCode based app that use sqlite databases. What issues do you get when deploying to the various platforms? Is Linux OK? Also I'd like to provide an IDE plugin that creates and uses an sqlite database - this complicates things as the different IDE versions will have different driver versions, and pervious versions di have a number of bugs as far as I could tell - Livecode 4.5 seems to have fixed a good number of these. However, I'm not planning on doing anything fancy, so having an idea of how well basic sqlite functionality worked out of the box in earlier IDE's would give some encouragement.

Re: Rev on two minimalist Linux distros
Thanks for the report Peter. It's really useful to get a feel of what is and is not working on these minimalistic Linux distros. On 16 September 2010 08:22, Peter Alcibiades palcibiades-fi...@yahoo.co.ukwrote: I have finally fired up Rev Media 4.0 on two minimalist Linux distributions as a start on the effort to discover whether the problems are really due to not having all the necessary files installed, and whether they are due to the mulifarious nature of Linux. I began with Slitaz and Tiny Core, the latter of which gives new meaning to the expression 'minimalist'. It is gui userland Linux system in 11 Mb. If we still had floppies, it would just about be deliverable on a handful. It uses almost none of the standard components. All applications have to be installed from repository. Both of these distros run in memory, so they are super fast. If you do this at home with Tiny Core, you should probably go with 3.1, just out. I used 3.0. It has 2.6 kernel, BusyBox, Tiny X, FLTK graphical user interface and flwm window manager. Without getting too far into the recherche details, this is not your standard distro. This is as minimalist as X windows can get. Get it here: tinycore_3.1.iso The other distribution is Slitaz, less minimalist, this has a whole 30 Mb and runs OpenBox, so a standard GUI, though not one most folks here may be familiar with. It comes with XOrg and LXDE bits and pieces. Midori as web browser, leafpad editor. It is a usable desktop out of the box, unlike Tiny Core. Get it here: slitaz-3.0.iso I did not use these in VMs, but on a spare bare metal machine we now have available. There is not going to be any difference if you run from CD in live mode, or if you install on hard drive, since in either case they both load directly to memory. I don't use VMs for this stuff in the interests of eliminating as many variables as possible. I made no modification whatever to Slitaz, but on Tiny Core, using the terminal, was unable to cd to the USB drive on which I had placed Media. I therefore installed PCManFM from the repository, which brought down a modest bunch of dependencies, including Gtk2, all of which went by in a flash. I didn't make a note of the others but can find out what they were if anyone is interested. It would be nice to know what people think should be tested for to make this rigorous. What I did was two things. First, some minimal exercise of the IDE. Created a new mainstack, dragged objects onto it, resized them. This worked fine. The font (yes, singular is intended) could be resized fine. The dictionary displayed and worked fine. You can alternate between IDE and browse mode. Buttons work. Second thing was, when I had a stack, I then moved it to another virtual desktop, popped over to the virtual desktop and clicked it. It instantly went back to the first one, where Media was open. So virtual desktops do not work here. It does not look like the problems could be missing dependencies. Rev seems to work exactly the same if its in one of these totally minimalist environments, including with Tiny Core which has out of the box almost nothing the big ones have except what you absolutely have to have to run the kernel and a command line, or if it is full fledged and bloated like Gnome or KDE. The environment I have found where Rev doesn't work at all is Ion2 window manager. This is actually a very nice working environment, its becoming my favorite. Its a tiling and tabbing WM. You have tiles open, and your apps take up the entire tile, in a tab. The tiles sit side by side on the desktop. It handles pop-up windows in an unusual way, they all appear at the bottom of the tile you are in. Rev does not like this, and it crashes. When you get used to Ion and know the keyboard shortcuts, its simply superb, fast, intuitive and very easy. You start apps from the keyboard with auto fill to help. Everything else seems to work with Ion, so this may be an indication that Rev is not standards compliant on the desktop issue. So, tell me what else people want to see exercised, and I will do it, this is just a start. And next week I will hopefully have time to do a full scale slackware install and bash around with that. I am not all that lively lately, and the latest is, have a proper phone system to install in addition to a server.

Re: [FOSS] On the creation of Rev to Web tools
On 15 September 2010 16:10, Malte Pfaff-Brill revolut...@derbrill.dewrote: I would be interested in how many people would really think they would be willing to invest some effort into various open source projects. I know David is a huge advocate of all things OSS. However, as Richmond pointed out pretty well, over the last 8 years I´ve spend in this community I have rarely seen OSS projects that took up momentum. I have been wondering why that is for quite a while now. My main thought is that it is not exactly easy to collaborate on rev Projects. It's mainly due to the economics of cooperating in Rev - too easy to develop solo, and partly due to the history of the community - it's average age is pre-open source / more share ware - so the culture is not there, and finally the community is a little small. For these reasons you need to do a little bit more than simply than place code up on server and declare it open under some undetermined license for a project to take off. This is partly due to the binary nature of stacks which makes it hard to use a version control system on rev projects, partly due to the lack of a place where projects like this could be hosted. The version control problem, is effectively solved now that we can create objects with IDs. It's a red herring anyway, as the majority of useful code can be shared under version control without problem. Current state: Everyone that tries to release stuff to the community is cooking her own soup. Though most people are very generous with sharing code on the lists and forums, there is no central repository where people can go to and collaborate on projects. We do have many sites spread all over the world with too many gems to dig out. Additionally we have revOnline. revOnline is a good place for consumers / prosumers though, not suitable for starting a collaborative effort to work on code. Especially libraries. Most of the stuff on revOnline is there for the visual stuff the stack does, or in a state where the lib is basically finished. So the only things an author that uploads to revOnline can gain is - giving examples what can be done - help someone solve a problem with a complex stuff (requires a lot of coordination and is usually easier done by mail) - show off what he has done. RevOnline does not work - it is not a collaborative environment, which is why it is easier for people to post urls to downloadable stacks than indicate there is a stack on revOnline. It should be replaced. What an author usually can not hope for is to benefit from changes other coders have made once a stack is released into the wild. I have no idea how many people here would really willing to dedicate time into OSS projects (my last try was rather frustrating, though it has been a few years since I last tried.) I might be willing to test the waters again in a couple of weeks. More on that later. Not many. They would when it works. The hard part is not the many, its the first 5. Ever tried to herd cats?

Agreed that would be hard short term, and probably doomed to fail long term. TWO ENVIRONMENT FRAMES ... Actions on the development environment do not work directly on the stuff we're developing but instead talk to the backend server that will follow the orders. WEB RUNNER CANVAS ... I have a Rev WebServer external ready for this project. Thats the second environment frame that I've mentioned above. It understands only Javascript. I don't see any need for this approach? perhaps you need to explain a bit more. What is wrong with getting the RevIDE to do all this client side? The only reason to do this server side that I can see is to build a business case around it. The RevIDe can do all this at lower cost - bandwidth etc, and there are no real maintenance issues with distributed rev tools nowadays. Don't get this. WEB SAFE TOOLS PALETTE INSPECTOR Replacing the tools palette with a Web tailored one with tools that we've scripted ourselves. They can mimic standard Revolution tools such as buttons and fields but they are not in fact creating Revolution buttons and fields but our own controls. We would also create our own inspector for setting properties of our own self made controls. I think this is almost right, except that the logic of replicating Rev controls is the wrong way round. Frankly the web controls are out of date, and less sophisticated no than those you find in JavaScript libraries. Also the audience and market is larger for people familiar with these existing JavaScript interfaces than the tiny Rev market. What is needed is to emulate the best and most robust JavaScript controls with Rev widgets - not the other way round. ... When we drop a button on the web runner screen, a POST call is made to the web server that picks this and creates a button javascript object, this is transparent to the developer. Again I can see absolutely no reason for the web server to do this - it's more work, and what is the benefit? The dragging components onto the canvas, can be done in the IDE. I demoed this at the last conference with widgets that are under version control on the server. This way Rev becomes a HTML5/JS/CSS development tool. We don't have the overhead of converting stacks to web because we're jumping that whole step working directly with HTML5 and friends. This solves control placement and interaction but does not solve script processing. In MVC terms (as you say) - the controllers and models can be on the server. This server side code could be on On-Rev, but equally there is no reason when any good robust server code could be used in any language, we just need to wrap so that the RevTalk based IDE handles it for us in the background. As an aside, the code I've been working on is based around the idea that we can have a more robust Rev based workflow (which speeds up native Rev development), and has the side effect of producing server based controller code - that can be ftp'd / transferred to the server and work there in exactly the same way as it does locally. The aim is to enable the sharing of this portable abstracted code, and build it into intuitive workflows so that it is generated in a natural way as part of coding in Rev. SCRIPT PROCESSING We would define a subset of RevTalk and create direct conversions from RevTalk to JS. As time went on we would implement more and more of RevTalk but some minimal subset should be enough for a start. Javascript is a wonderful language and converting scripts to it is the most safe option. Yes - I think we are on the same page here. I see a sub-category of shared code, which could be translated into JavaScript or other languages. People would do this in order to allow their projects to work with existing online frameworks, while allowing local prototyping in RevTalk. The workflow is natural, and allows for gradual evolution of code bases based on incremental incentives that benefit the end user. I think it could work, especially if it were part of an explicit open source / open content strategy by RunRev, in which they took and supportive but indirect role. The elegance of this approach is that we can begin with a fastCGI engine for the script processing by directly executing RevTalk script on the FastCGI process without translation I still don't see any advantage to this - maybe I am missing something? And FastCGI is AFAIK not the way to go now anyway? We could build this and release under BSD license which would enable business to use it in the commercial offerings and thus making it attractive and incentive sponsorship.

Not unlike the mongrel/ruby coupling. You'll be working all on client side. No wasted bandwidth or extra CPU power required. You need, in my opinion, the server running to be able to develop in an environment that is equal to your deployment option so that you don't end up with cycles such as: 1 - build stuff in Rev 2 - convert it to web 3 - run it and it does not work or does not layout right 4 - back to Rev If you're constantly building and tweeking inside a HTML5 enabled window, you get the following benefits: 1 - You avoid any conversion need since you are already on the deployed environment 2 - WYSIWYG approach, what you see on the canvas is exactly what the client will see, no need to compile or translate anything This way we maintain one of the strongest features of Rev which is being able to develop incrementally avoiding the overhead of compile-debug-code loops.

Re: Reducing flash with revVideoGrabber - any suggestions?
AFAIK - you've done the best that you can do with rev based hacks. Maybe you could contact Kevin and ask for the source code? I think there are a few other people that would really like this external improved and it would make a great open source project - especially if you could put a small ransom on it? On 13 September 2010 12:32, Ben Rubinstein benr...@cogapp.com wrote: I'm working on a kiosk which will regularly record short clips of video. At a certain point in the sequence I open the video grabber and start previewing the video; subsequently I start recording, then switch back to preview, then close the VG altogether. Rinse, repeat. Each time the VG is initialised, the VG rectangle goes white for approximately three quarters of a second. Unfortunately in our design the screen is mostly very dark, so the white shows up really strongly. I've tried various things to reduce this - eg tying the video grabber to a featureless borderless sub-stack the size of the video rectangle, and hiding it, putting it offscreen, or putting it behind the mainstack while it initialises. Most of these fail altogether. The best I've managed to do is with the substack hidden; initialise the VG, start previewing, and give it a full second before showing the substack (I've noticed when the video actually starts, it also sometimes (?) appears dark, and takes a few frames to come to a balance - presumably this is down to the camera). Doing it this way I still get a white flash, but it's extremely short. Although the substack is hidden, the flash appears where the substack is. So I can manipulate the position of the flash, by moving the hidden substack before I initialise the VG, and then moving the substack into the correct position immediately before making it visible, after the VG has had its second to 'warm up'. If the hidden substack is moved entirely offscreen, then the whole thing fails; there's no flash, but when the substack is moved back into position and shown, there's no video either, just a white rectangle. However, if the hidden substack is partially onscreen, partially off, then the white flash is limited to the area-that-would-be-visible-if-the-substack-wasn't-hidden, and when the substack moved to the correct position and shown, it all works correctly. Hence the best I've managed to do is move the the substack so far off the bottom right of the screen that there's just one pixel it of it onscreen; the white flash is then reduced to a single pixel. Unfortunately because the overall design of the kiosk is very dark, this is still visible - but a lot less intrusive than what we started with. Although having to warm up the VG a second before I want to use it is a bore I can easily fairly easily accomodate this within the control flow. So I do now have a reasonable workaround (confession: I hadn't got this far when I started writing this email). But is this the best one can do? Is there a better approach altogether that I've missed? (The obviously completely different approach is to initialise the VG once when the kiosk launches, and leave it running all day, hiding and showing the preview/record stack as necessary. However this is going to be in a high-traffic and high-profile location, from launch, and there's not long before launch; so I'm nervous about doing this without more time for soak testing, given various anecdotes I've heard about drifting sync etc. But if there's contrary experience that this can work reliably, I'd be interested to hear about that also.)

Re: Pattern recognition of basic shapes in Rev
On 17 August 2010 19:30, Randall Reetz rlre...@gmail.com wrote: I am working on two such filters. The first is a brute force recognizer looking for matches to standard shapes (point, line, angle, triangle, rectangle, polygon, oval, conic and cylindric sections) and how closely a user drawing matches platonic forms of these (exp. right and equilateral triangles, square, right rectangle, golden rectangle, parallelogram, circle) at any rotation. The second filter is one I have been working on for 15 years and is a universal pattern engine which does the same as above but without a set of arbitrarily pre-defined target shapes. From the self-evolving AI perspective from which I work, I consider the first filter set cheating and embarrassing (but hey, it is far easier to pull off). By the way, anyone can copy a code library or algorithm. I am always interested in the ways different people go about solving problems like this. The way I attack a problem is by collecting salient data. What can I know about these user created polygons (number of points (or line segments), vertice angles between segments, relative segment lengths, relative distance of each vertices from the object's center of area, open or closed, etc.)? Once this data is collected and stored for all user polygons, it can be compared with the same data collected from platonic shapes. How would you go about solving this problem? I'd Google for a library :) But that's because it is not the problem I'm interested in, but a tool that would improve the user experience. It's also because I'm pretty sure it's a problem that soon will be addressed by the gesture recognition stuff in the OS, and developing my own hack would well just be another hack. If I were to do it now, my guess would be to avoid logical solutions based on knowledge of geometry, and to take one of the C++ based genetic algorithm libraries out there and train it on a set of user data. I did play with both neural networks and GA's in MetaCard, and used some of that work in music composition. Certainly very interesting areas - but right now I just want the user to be able to draw polygons with their finger :) ___ 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

I'd like to emulate the behavior of some software which allows you to draw rough shapes by hand and recognises whether you want to draw a circle, triangle, rectangle etc. The tools would allow you to use the freehand pen polygon tool to sketch and then replace the sketch with an appropriately placed polygon or button.

Re: ANN] Translating your Rev stacks into web apps
OK - I was not thinking of anything detailed, but in principle I would think that a good number of people on this list researching how to get into web app development and leverage their Revolution experience would research these two alternatives, both have been covered in discussions on this list. In simple terms PhoneGap is an open source JavaScript framework which allows you to create mobile phone app's using your basic (ish) knowledge of standard web technologies. In particular you are able to create iPhone applicationshttp://phonegap.pbworks.com/Getting-Started-with-PhoneGap-%28iPhone%29by using standard html markup calling the PhoneGap JavaScript library and compiling these suing Xcode. The resulting mobile apps are designed to run on iPhone / Android / Palm / Blackberry / Windows Mobile and Symbian platforms. As it is open source there is no charge for the code, but for iPhone development you would need to pay your $99 blood money to Apple. I've not used it myself, but am looking at interfacing it with Revolution, by creating a set of open source libraries that would translate between Revolution widgets and PhoneGap code / widgets. In many ways this is similar to the aims of Rodeo. I think it would be particularly strong if Rodeo used or interfaced with the open source PhoneGap framework, as this may make the eventual aims of supporting an iPhone app store submission service easier to implement? In contrast TileStack http://tilestack.com/ is not so interesting I think - it looks like a more or less complete clone of HyperCard written in JavaScript - like Rodeo it is a hosted service, and like Rodeo i don't think the JavaScript is an open source framework - it is not specifically designed for mobile or webkit / HTML5 - so that is another difference. If anyone has more detailed experience of either of these products I'd be interested in their experience. I know that early versions of PhoneGap were pretty limited - but it has been around for a while now.

Re: Have you discuss here already that Apple changed SDK to allow cross-tools ?
There is no lock-in with Unity - or so it seems to me. As I understand it it outputs source code to Xcode, which you can tweak and enhance as you wish. If that is the case then Apple need not fear platform lock-in - and so they could agree to license it - though no decision has been made yet as far as I know. I'm not sure Unity outputs source code - I have only gathered this is the case from other posts - but if it did then according to the lock-in logic Apple would have nothing to fear.

This has been troubling me. Steve jobs is reputed to have said: “Something like HyperCard on the iPad? Yes, but someone would have to create it” at the Apple’s shareholder meetinghttp://www.macworld.com/article/146739/2010/02/2010appleshareholdermtg.htmlsome time in early 2010. The closest source to this I can find is herehttp://www.macworld.com/article/146739/2010/02/2010appleshareholdermtg.html(the relevant section below is at the bottom of the article): As usual, there were also a number of off-beat comments and questions, ranging from suggestions that Apple invest in Tesla Motors (Jobs: “We were thinking of a toga party, actually”) to a request for a flagship Apple Store in Cupertino (“I’ll pass that on to our retail team”), to a suggestion that Apple partner with Nintendo (strategic alliances are hard, but possible if it’s worth it), to a desire for a simple programming language on the iPad (“Something like HyperCard on the iPad? Yes, but someone would have to create it”). Jobs declined to comment on the possibility of a Verizon-network iPhone. So it was a casual remark - not thought through maybe? I'd be tempted to be generous on this one - and figure that he meant what he said. If so it would be real interesting to ask on what legal and technical basis someone could do that. I don't think his answer would be along Rodeo lines - that is you'd have to create web app's. So perhaps it is worth asking along which lines a real HyperCard app could be made on the iPhone? How about a community drafted letter - one directed specifically at this question and to clarify his thinking on this? What would such a letter look like? Which is the best open platform out there to draft such a letter together and collect signatures? NB - I'd be tempted to think that one possible answer which would square the circle (with regard to Apples concerns with a middle layer lock in) - is if the HyperCard app on the iPhone was open source. Then there would be no lock-in against Apples interest as if they or any Apple developers wanted to improve and add platform specific features they would have the power to do that? That is surely part of the logic behind why JavaScript is OK. ___ 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
Rodeo: 2 questions
Hi Jerry, I'm still reading about Rodeo and trying to evaluate whether to take the plunge. there are a couple of things I don't quite get: 1. The web apps being served by On-Rev: Rodeo server is a highly-scaleable, secure, n-tier architected cloud solution. So there is no way to author and then serve from our own servers, and that means a minimum $10 a month fee for hosting. What about bandwidth? What if someone creates a wildly popular webapp - can they serve some content from a CDN? Any ideas how you would charge for that? 2. Is there any specific strategy offered by On-Rev in your server set-up that allows true scalability and load balancing across regions etc? Or are we realistically going to be stuck with a single shared or perhaps even private server without the ability to scale that? OK for a the vast majority of apps this won't be an issue - but having the option to scale in the event is still an issue. ___ 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

It is not exclusivity that is being asked for. It does not matter that Rev was offered for one platform or many.

Control to ensure that the lockin does not migrate to any software platform that is offering pan-platform middleware - whether that be Adobe or RunRev. The fear is that cross platform development incentivises prioritising the lowest common development, and the largest installed user base - which by most accounts will soon be Android. Apple thinks it has an edge by competing on the basis of design quality and constant innovation in the hardware and OS - which it needs to trickle down to developers. If a tool maker does not implement the latest features fast enough then the cutting edge products are dragged down waiting for the tool makers to implement features, which they are only motivated to do when the market is big enough. So the fear, which is justified IMO, is in lock-in to proprietary middle ware that Apple does not and cannot control. The question I am asking is are there not other ways to square the circle - and would open source be one of those ways? If it were then you might expect some of those iPhone platforms that export modifiable / open source code to be accepted some time soon.

Cloud computing: scalable DB
I'm looking into an application which needs a highly scaleable back end database. One with low up front costs and yet won;t fall over if it suddenly takes off. I've noticed Jerry and others describing On-Rev in terms of cloud storage - but AFAIK it is a simple shared host, and there are no services on offer with regard to scaling or true cloud computing? So - I am looking at using true cloud based database solutions. On-Rev would provide that administrative functions but web plugins on users own web sites would directly call the cloud computing backend. I'm looking to prototype this in revWeb and then implement the plugins in a suitable AJAX framework. It seems to be that this is now a reasonable approach to take given the existing state of these services - but I'm only reading about them and would love some feedback from others on the list. In particular I am looking at using Amazon - either their SimpleDBhttp://developer.amazonwebservices.com/connect/entry.jspa?externalID=2552categoryID=146, or their Relational Database Servicehttp://aws.amazon.com/rds/?ref_=pe_8050_15319810, but maybe also Google equivalent services?

This kind of problem is easily solved with the above solutions and harder to code with plain old relational systems. I particularly like the idea of not having to get into complex relational db design, but using simple parallel tables and doing the joins in the application layer ( ie revTalk) - seems the way to go to me - if you can break the data into object-like chinks where your parallel queries retrieve small quantities of data that you use revTalk to massage - sounds great.

Re: revigniter - Model-View-Controller in Rev terms?
Hi Ralf - I'm going to take a second look at revIgnitor - and pretty much agree with the entire approach and the mapping of MVC concepts to Rev. I am looking forward to integrating my code into your framework :) This is how I see the mapping: *View* Yes the visual appearance of the interface that lays out the data on screen ready for interaction. But specifically it includes any presentation logic such as code for resizing the view, or changing it's visual appearance. Also in general I feel that views map to groups with behaviors - therefore the Datagrid is a view. you should be able to drag and drop views onto cards and ideally nest them within each other, and to do this in a way which is completely independent of your particular applications logic and data. These views usually have custom properties that allow you to get and set their data in a standard way and also to change their appearance - a test of their MVC'ness is the ability to move them around and use them as is without editing their code in any way. I have found it very useful to test out views precisely this way by keeping them in an external library and testing the ability to drag and drop them into a variety of situations (manually or under script control). It would be possible to consider some cards or even stacks as views - so far I don;t do that - but it is possible for instance to automatically create stacks as dialogues which contain group views - so for instance I use the standard video, image, xml, and tree views to display data in a window using a command such as display_Image someUrl which creates a new stack, and copies the image view to that stack. It's a side effect of creating a good view that you also create some good dialogue stacks. *Models* I've not done that much on these and intend to use Trevors sqlYoga, and / or the work that Ralf has done. The important bit for me is the ability to move from arrays to databases - so I have an abstraction layer that uses arrays, but can easily be switched to XML or a database. *Controllers* The glue. I agree with Ralf that the best place usually for this code is the card script. And in simple terms it does everything else required to glue the views to the data. It is where the code that really defines the logic of your application is. I have a way of creating this code which automatically creates a basic interface - so this is often where I start coding -dragging a few basic views onto screen to display the data, and gradually defining the model. At the end I create new custom views for the application - perhaps by cloning one of the existing ones and if it is useful adding it to the library. ___ 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

So i decided not to wait any longer for the ipad dream, and to launch my first app as mac and windows desktop !! I also decided to dig javascript as it has become so central nowadays; being at the heart of webBrowsers. Wanted to share views on that : I identified SproutCore framework and wondered if Jerry is working with that kind of framework!? It seems there is now 3 approaches to javascript-webapps : - thin client (all done on server side, eg that standard dynamic CMS sites on-rev excells at) - fat client (static HTML5 CSS with lots of Javascript all around that can directly interact with data servers, like SproutCore) - and.. a sportive approach.. which I thought off with on-rev, which is a dynamic CMS using .irev scripts the most and as little javascript as possible, and possibly jQuery scripts to keep cross-browser compatibility... .. and that is where RevIgniter, which I found so impressive seem to go! : This version includes a new library, which lets you write jQuery code for event handling, animation and Ajax interactions using revTalk. Now sproutCOre has a touch librairy and an IDE just out of the oven... and with phoneGap still being ok with apple new strategy.. it seems like an interesting doable route for mainstream information orientated iphone apps. [and we'll soon see what rodeo brings in that arena too!] I'll be testing those 2 frameworks shortly and let know.. and of course any views, maybe on a separate thread? -- as far as the main subject of this thread was... Kevin's annoucement, to make it short : I'm ok not to have any money back from the mobile program (to be crude about it...) BUT I would like A) to get ANDROID mobile instead of iPhone (seems fair! eventhough i'll ditch my dream regarding iPad). If we get maemo, window mobile and android : we'll be kings! and thankfull to runrev!! Because if ever one wants to cover the whole lot of mobiles, javascript and HTML open up : iPhone, webOs, and Blackberry.. another good reason to consider javascript as language n°2 as a complement to xTalk! and B) Also just ONE MORE STEP for the on-rev : the possibility to have closed STACKS instead of opened .irev so that a market can develop there (this is a year long awaited request!) To my view the revWeb plugin is kind of useless road which I would not pursue at great expense, since javascript seems to provide the fuel for webapps now (demos at SproutCore). I must was enthousiastic at first but just cannot make it to rely on that one. I would prefer that a minimal audio/video library be made, like the datagrid enhancement of last year (simple fade in and out, cross fademix, minimal reverb, tone correction and normalization) and possibility to ouput a compressed quicktime format. It is important to be able to produce good quality audio/video by program too since runrev claims to be a media platform. -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Thoughts-on-Kevin-s-announcement-tp2172675p2215870.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 ___ 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: Will revCGI be made available (not just revServer)?

I'm not exactly sure what it is, but when I asked if it was a module per se I was told it was not. That's a good thing, IMO, since it would be next to impossible to install it on a shared host if it were. I'd like to know as well - personally I fear ti will be worse than that and the revServer that you can install will be a complete integrated server that you will need you own dedicated server for - in which case it would be impossible to install on a shared host, and worse still pretty unlikely that existing hosting providers could be talked into installing it (which they might if it were an Apache module with appropriate security audit / certification). I don't know this to be the case - but nothing said so far publicly indicates anything other than the equivalent of a company could freely install it to run their own server.

Re: Thoughts on Kevin's announcement
Jerry - it would be good to outline a little more clearly how Rodeo works / fits into the picture of how to develop apps on iPhone for Rev developers. I'm not clear - so I guess perhaps others are not. At present you have to make iPhone apps using either: 1. Cocoa Touch http://en.wikipedia.org/wiki/Cocoa_Touch and Objective Chttp://en.wikipedia.org/wiki/Objective-Cusing Xcode and the the iPhone SDK http://en.wikipedia.org/wiki/IPhone_OS#iPhone_SDK 2. Use open web standards and Xcode with or without open source frameworks such as PhoneGaphttp://phonegap.pbworks.com/Getting-Started-with-PhoneGap-%28iPhone%29 3. Other? You could also just create iPhone tailored web sites (with or without JavaScript frameworks to help out): - http://news.cnet.com/8301-13579_3-10295121-37.html - http://www.mobiletopsoft.com/board/7600/google-voice-web-app-now-available-to-iphone-and-webos.html I'm sort of assuming that Rodeo is an app written in Cocoa Touch/Objective C/Xcode which reads and writes structured data to the web server. You therefore have an authoring app and a web service. The web service is able to customize an Xcode project, and therefore create an app from this data for you, which you then aim to submit to the App store. Questions: - Is this right? - Is this not simply using web services to do the same thing as any other framework that automatically generates Objective C for Xcode - and therfore could fall foul of the originally written clause on the new license? I am trying to choose between the web app approach, the PhoneGap approach and Rodeo - thanks ___ 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

What I got from the article is that the journalist was saying Apple is not a threat to Nintendo at all, because they are really producing two different non-competing products. And my take is that Apple is not producing anything in the way of end user software on the gaming front anyway. They are providing a way to get software to the end user that small developers could never have hoped for prior to the iPhone. Have to disagree there Bob: 1.

Re: Check out Jerry's new videos -- ALICE port
Yes I did - but this was a very very long time ago - back when i was using MetaCard (some time last century - so I can't vouch for the code quality). I was interested at the time in using it for customer service and game applications... and in the end I figured it was better to simply run an Alice server and call it as a web service than have to maintain an extra code base.

Me too! Actually, in the same way that it looks like the future of consumer oriented operating systems at Apple is going to be the iPhone OS, it also looks like the (consumer oriented) Linux of the future is going to be Android. For me, this bodes well in the longer term for Revolution. That is because at last RunRev will be forced to prioritize both Linux (ie Android) and to create a robust open source development strategy. I'm NOT talking here about open sourcing all of the Revolution engine - but because of the way I understand RunRev are proposing developing for Android, it does seem that there will be a need to start to engage with a wider open source community. This is because the Rev engine will be called by Android front end widgets - which in turn will be open source. In other words the front end will be open source and the Rev back end closed. This in turn will mean that belatedly RunRev will inevitably be led down the path of learning how to use classic open source community building strategies. This in turn will have spin off benefits for the server side integration with other open source platforms. I'd predict that in time, Apple will open up, and we'll get Rev on iOS, so while I love the iPad and iPhone platforms as consumer oriented hardware (and will have to shelve 2 iPad related projects) - I'm secretly really pleased about the new focus on Android :) ___ 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
