Flash and Open Source
Anders Schneiderman asks: "I'm involved in a project that's planning to create open source toys for educating people around complicated policy questions (e.g., policy on prescription drugs). We'd really like to use Flash as our main language, but we're concerned about the fact that the major Flash development tools cost $500--more than some of the community group folks we want to involve can afford. I took a look at Sourceforge, and while there are plenty of projects that offer ways to create Flash for free, there didn't seem to be any v.1 general development tools. Did I miss something? If you want to build Flash and you don't want to pay $500, how do you do it (aside from copying somebody else's, which as Bill Gates told us is just bad, bad, bad)? And if there aren't any powerful open source tools for it, any thoughts on why?"
This is a problem I've hit before. Unfortunately the open source community hasnt produced any Flash development tools since many users of OSS are anti-flash. This is mainly due to the fact that no matter how glitzy, Flash is still not supported by the W3C as an accepted internet standard. Plus PHP works wonders with graphics. Nevertheless, maybe it's time we asked Macromedia to help us out??
SVG is a W3C approved vector graphic and animation XML language. Development tools for it are coming right along. There is a good series about SVG on XML.COM. The author demonstrates many flash features using SVG.
Flash is a well-designed format, and the format is known and documented. It could be used for more things. I'd like to see a PowerPoint replacement that used Flash, for example. PowerPoint files are incredibly bulky; Flash is compact. Plus, you could put your presentations on web pages without much hassle.
Flash is also useful for user interface design. Many video games use Flash for the 2D API. That approach could help the open source community transition from bitmap-based to form-based APIs.
And just having a good open-source draw program for when you need a diagram on a web page would be a big help. It's annoying that Linux documentation seldom has useful diagrams. And if there are diagrams, they're raster images that can't be usefully edited. A good Flash-based lines-and-boxes program, like early Visio, would be valuable.
Macromedia's tools have a keyframe animation mindset, but that's not inherent in the Flash format. It's just a Macromedia bias. There are lots of interesting things to do with Flash and its object stream / event stream format.
Actually, no they wouldn't get sued, and Flash rather open. In fact, there is Ming, an extension for PHP, and even FreeMovie, http://freemovie.sourceforge.net/, which is currently moving to support the following:
FreeMovie/C#
FreeMovie/Java
FreeMovie/Perl
FreeMovie/PHP
FreeMovie/Python
FreeMovie/Rebol
FreeMovie/Ruby
FreeMovie/Tcl
FreeMovie/VB
FreeMovie/VB.Net
So the real question is, "How do you want to flash today?"

dude. the ability to make embeded apps that work better than Java and are more powerful than Javascript is invaluable.
I got a buddy who is doing a web development class and he chose flash for his app so that the User does not need to download a new page everytime a serverside script updates information.
faster than Java, nice looking than Java, and has all the power of a serverside script without all the page reloads....NICE!!!!
I am the Alpha and the Omega-3
Being a beginning Flash developer myself, I can attest that it's probably next to impossible to produce a full-bore "budget" tool to create Flash files.
This isn't HTML we're talking about here. Flash files use coordinated timelines, compressed files, and loads of user interaction to do what it does, and it's not cheap. You can't just open the source code and peek inside. It's probably going to be some time before any open source project can produce the complexity Macromedia's put into six versions of their product.
As others have pointed out, though, you don't really need to use Flash. 99% of the time it's just that: flash, pretty animations which are implemented badly by non-professionals in order to make their site look cooler than it needs to. Most people honestly just want the information. You should consider this.
However, if you're persistently determined to use Flash, then I'd recommend buying a used copy of an Flash 4 on eBay or somewhere. It's certain to be better than any of the open source products currently available.
The reason Flash isn't more "open source" is because it is ultimately a proprietary technology under the tight control of the Macromedia company. Although Macromedia has released a publicly available description of the internal flash file format, this in itself does not an open-source standard make:
* The description Macromedia released is incomplete in some areas, and has not been kept up to date with more recent versions of Flash.
* I've used Macromedia's documentation to write a Perl library that outputs and modifies flash movies. I've found format to be highly optimized for playback unfortunately; you can't do much to modify existing movies in interesting ways (aside from moving existing elements around the screen, rearranging letters and so on).
* Macromedia has not released a description of the Flash *project* file (thus giving them a tight reign over authoring tools). Significant information is lost when a project is published in the (documented) flash format - information that would lend itself to making more dynamic and interesting sites.
* Macromedia likely does not view the prospect of 3rd party authoring tools as being a good thing, since Macromedia is largly an authoring tools company.
Finally, I'm a bit perplexed why you would choose Flash as a good tool for educating people about "complicated policy questions" - this strikes me as something that would be served better by a more dynamic text-oriented approach (such as a Slash-code based site).
One of the problems with Flash is that it doesn't lend itself to sites which have a large amount of interaction between their users and the site authors. You can do it, but it's a huge pain-in-the-ass.
So I'm assuming you want to create a flashy presentation, and not much else.
The W3C SVG page may be found here. Probably the most popular browser plug-in is made by Adobe and you can get it here (RedHat 7.1 and Solaris 8 versions of the plug-in are somewhat hard to find but are still available).
You might also wish to check out some of Adobe's demos. Jasc has a Win32 app called WebDraw that can come in handy, too.
Please read the whole comment before moderating...
As I understand it, the question can be translated as:
"We're developing a new education product in Flash. Instead of hiring developers to help us design the interface, we would like to call it 'open-source' so we can get people to work on our product for free. We're really too cheap to even supply a basic development tool to our workers, so can we mooch off someone else's work by using a free product?"
Please forgive me if I'm assuming too much, but it really sounds like you want someone to have duplicated Flash and put it on the market for free. Now, having stated something that could be considered "flamebait", I will give you some advice.
-- Don't use Flash. I know that a lot of the tech-heads here on Slashdot will say this as enitre comment and get moderated up for it. I happen to not use Flash, but I do also happen to realize that there are very valid reasons for using it, and that education is one of Flash's core markets.
If you are not willing to pay your developers or at least buy them a tool for their work, use HTML. Most likely, the people on this project will already have a preferred HTML editor, which will enable you to just use CVS or another versioning system to check in the documents.
What bothers me about this whole post, though, is that it epitomizes the "bottom-feeder" attitude of companies that really want to profit from people's hard work without paying those people for that work. To avoid this, I would recommend gathring a core development team and paying for the tools that you believe that team needs. Then, you can release your product so that the masses can update it, with the caveat that the people updating it will need a development tool that they will have to pay for on their own. Everyone goes home happy: you sell a product, your development team gets paid a small amount plus experience, and your customers can update the product on their own accord and with their own tools.
Open-source software usually fulfills a need of the developer(s). I would say that the reason that there aren't free Flash development tools is that either a) Flash is such a good product that the people who use it are willing to pay for it or b) not that many people feel a need to use Flash. It's probably some of both.
Another thing: how do you release a Flash product as "open-source"? Do you distribute your product's SWF files to the target audience? I'm not sure how that would work. Is this something you have considered?
I apologize if I read too much into your statement. I hope that you really did have good intentions and weren't just riding on the "free [as in beer] is cool" bandwagon. I'd appreciate a good response from the original poster or someone who is involved in a similar project. At face value, it seems that there are a lot of "holes" in this project plan that haven't quite been addressed.
Simpli - Your source for San Jose dedicated servers and colocation!
There are a few tools for Flash and Open Source, but they are pretty much code oriented. The first is Ming, which can be found at:
http://www.opaque.net/ming/
The second is libswf, created by SGI. I'm not sure of the status of the license, but the source _is_ available.
ftp://ftp.sgi.com/sgi/graphics/grafica/flash/
Both libraries are accessible from PHP.
As far as vector tools, Sodipodi is an incredibly cool vector editor. Unfortunately, at this time it is only svg, but you may find it useful.People have for quite a while wanted flash for sodipodi, and all one has to do is tie the Open Source flash libs to the UI. But nobody has done it. Read a post about it on the Sodipodi web site.
I hope you find this helpful.
Finally, I'm a bit perplexed why you would choose Flash as a good tool for educating people about "complicated policy questions" - this strikes me as something that would be served better by a more dynamic text-oriented approach (such as a Slash-code based site).
I couldn't agree more. Perhaps the reason why these policy quesitons remain complicated is that the people put in charge of creating educational tools have no clue about how to deliver simple, succinct answers.
Flash indeed.
Takahashi Rumiko made beats! DON, taku, DON, taku. . .
There is a reason the BLINK tag is dead.
that is not an accurate or mature attitude towards flash. yes.. the blink tag is dead, and for good reason, but in case you haven't seen any promotional websites for things such as movies or events lately, you might be interested in knowing that your version of the future of the web is boring. Yes, a good website is one that offers dialup and text only browsers lusers an escape trap, but flash has some very entertaining possibilities on the web. Of course it has no place on a site like slashdot.. but fine.. move on from sites that use it.. you are seriously missing out.
I happened to have loved the recent E.T. website, completely done in flash. The sounds, images, and interactivity were very interesting.
Sorry about your connection, or browser, or lack of interest in web media. It must be boring where you live.
flaimbait? perhaps.
As for the slashdot question,
If you want to build Flash and you don't want to pay $500, how do you do it
you do it with swish.
it's not as fancy but it will do the basics.
