If you are just planning to upload file to S3 and do not need to manipulate them else do anything to them before they end up on the server.  Then I suggest you just use the plugin.

simply install 

script/plugin install http://svn.techno-weenie.net/projects/plugins/attachment_fu/

after that just follow the instructions on http://clarkware.com/cgi/blosxom/2007/02/24 you should be up and running in no time with the help of this plugin

Lets assume you don’t want to use the plugin

But why would we not want to use the plugin:?

1. Way more code than you need for the task at hand
2. No simple way to manipulate the file or extract data from it before sending to S3


So now that we are going to perform this operation manually there are a few things you will need for this example. You will need to install the mp3info gem as root at command prompt.
gem install mp3info
gem install aws-s3
Say yes to any dependencies once those two gems successfully install you will have to restart your webserver and they will be ready to use in your application

I’m going to skip over a lot here because I don’t know how you want to configure your application however the steps are pretty simple create some scaffold. Make an upload form.
and then save the data. I’m only going to show you the model code. I believe everything is self explanatory from there. I will be happy to field any questions if anyone cares to ask. Enought chit chat show me the code

        File.open(”#{tmplocal}/#{tmpname}”, “w”) { |file| file.write(@file_data.read) }
        mymp3 = Mp3Info.open(”#{tmplocal}/#{tmpname}”)        self.id3tags     = mymp3.tag
        self.bitrate     = mymp3.bitrate
        self.samplerate  = mymp3.samplerate
        self.samplerate  = mymp3.samplerate
        self.mpeg_version= mymp3.mpeg_version
        self.layer       = mymp3.layer
        self.length      = mymp3.length
        self.file_size   = @file_data.size
        mymp3.close
        File.delete(”#{tmplocal}/#{tmpname}”)
        self.mp3_url = get_file_url
      end
    end
   end
   def get_file_url
    “#{user_id}/xrays/#{id}/song/#{@file_data.original_filename}”
   end
   def connect_to_amazon
     Base.establish_connection!(:access_key_id=> AppConfig.ec2["access_key"], :secret_access_key => AppConfig.ec2["secret_key"])
   end
end

That is really the meat and potatoes. It is all hanging out in the model nicely tucked away. getting the data out of S3 is simple and is left as an exercise for the reader. Obviously you need to insert your own access_key and secret key. I’m not making any assumptions about the configuration of your application and thus this is entirely us to you the reader as well. Hope this helps someone..

It just throws this weird error:
Unable to open external editor…
(com.adobe.flexbuilder.ui.osx_3.0.194161)
Sort of more about the error here…

With a little research it seems that this is a problem with the System Editor settings with Eclipse itself (which Flex Builder is based, for the noobs like I me).

So taking a bit of a shot in the dark I looked through com.adobe.flexbuilder.ui.osx_3.0.194161, and it didn’t seem to have anything other then commands to open system editable? files. So just deleted the package from the plugins folder (actually i moved it to a plugins-disabled folder in the main Flex directory), and holy crap it worked!

So far I and my co-developer Sean, and our intern Derek haven’t come across any other errors, or changes in performance, just the unfettered ability to double-click FLAs and watch them load in Flash.

Give it a try and lemme know if your results vary. Though I suppose you should be doing so at your own risk…

At any rate the budget was good, but the timeline was a little tight, and I was still getting my head around AS3 and the new Flash 9 features.

So I had this idea:

I’m working with a bunch of designer’s who are really good with illustrator, and keyframe animating, but don’t have the time to animate all the movements (each head, body, upper arm x2 lower arm x2, legs, hands, feet… well you get the idea). So I needed a way to reduce the number of animations that the designers would be needed for, but also not create too many Tweeners or other hard coded animation solutions. I really needed bones, but those don’t seem to be arriving for a while, so the next best thing was automatically animated elbows (and knees). Fortunately for me the illustrator I was working with designed the robot’s arms and legs with even length upper and lower lengths so I could do some trig and get this:

[-]^?View Code ACTIONSCRIPT

1 2 3 4

var theta:Number = Math.acos((distance/2)/limbL)*180/Math.PI;   this.limb.rotation = baseRotation - theta; this.omoLimb.rotation = theta * 2;


Click and drag the hand or foot to see the automagic joint rotation

AS3 Joint class source file

Right now it’s limited to even length bones, but my little brother with the physics and math degrees, says he has a better equation, so as soon as I have time I’ll update the classes. A public SVN repository is in the works too, stay tuned.

I’ll post about my experiences with red5 at a later time. However, for now I think you should check out this excerpt from the rsyslogd man pages. We are using rsyslog in the hopes that we can log all the red5 events to a centralized server for easier reporting. Check back for updates on that. As always if you like this article please digg it and or leave a comment so we don’t feel like we are talking to ourselves…. Enjoy

This type of highlighting seems trivial. However to do it in rails in a nice elegant way is not obvious. So without further a do, I present my method. This method dis-involves the controller which makes for a cleaner more centralized place for managing your highlighted navigation.

The primary thing required is a method for creating navigation items. I choose to put my method / helper. in the app/helpers/application_helper.rb that way it will be available to all all of my views. The method I chose to use is

[-]^?View Code RUBY

1 2 3 4 5 6 7 8 9 10 11

def nav_selected_no_span(hash_name, selectedkey ) result ="" hash_name.each do |item| if(item[0].to_s== selectedkey) result +="<li class="selected"+item[0].to_s.gsub(" ", "_").downcase+" selected">"+link_to(item[0].to_s,item[1].to_s)+"</li>" else result +="<li class=""+item[0].to_s.gsub(" ","_").downcase+" ns">"+link_to(item[0].to_s,item[1].to_s)+"</li>" end end return result end

This function is fairly, simple what it allows you to do in your view is, make an unorded list of your navigation items. You would use this method most likely in your app/views/layout/application.rb. An example of the navigation from howcuteismypet.com is:

[-]^?View Code RUBY

6 7 8

<ul> <%= nav_selected_no_span([["Vote On Pets",home_path],["Best / Worst",best_worst_path],["Most Recent",most_recent_path]], params[:location] ) %> </ul>

The important thing to notice is the params[:location] the function above says that if params[:location] matches one of the names like “Vote On Pets” then highlight that item. Pretty simple. Then in your css you can define the rules that make something selected. Now you may be wondering where params[:location] is set. And you would be correct to wonder that. That parameter is actually set in your routes file believe it or not. As an example i’ll show you the route for “Vote On Pets”. located in config/routes.rb your could do something like this.

map.home '', :controller => 'index', :action => 'index', :location=>'Vote On Pets'

if you wanted most recent you would do something like this

map.most_recent '/most_recent', :controller=>'index',:action=>'recent',:location=>'Most Recent'

The location parameter is sent to the helper and the correct items is selected. So I hope this helps you in your efforts to stay dry and much more organized.

Questions and comments are very welcome on this blog. We like to know we are not talking to ourselves, so if you would like further explanation please feel free to post a comment.

I’m not sure what he meant by a cervical shaped accordion though… Circular maybe? hopefully?

source files for the xml’d accordion

The Actionscript

[cc lang='actionscript']
private function init()
{
var request:URLRequest = new URLRequest(”wp-content/xml/images.xml”);
loader = new URLLoader(request);
loader.addEventListener(Event.COMPLETE, loadComplete);
}

private function loadComplete(evt:Event)
{
data = XML(evt.target.data);
trace(data.panel.length());

accord = new accordion(500, 400, data.panel.length(), 20);

for(var i:int=0; i < data.panel.length(); i++)
{
var panel:MovieClip = new NavPanel(data.panel[i].name);
var contents:MovieClip = new ImgHolder(data.panel[i].img);
accord.addPanel(panel, contents);
}
addChild(accord);
accord.openPanel(1);
}
[/cc]

The XML

<?xml version="1.0" encoding="UTF-8"?>

Something that has been solved hundreds of times. However I didn’t want to fuck around with a special user interface framework like http://developer.yahoo.com/yui/. Since I use prototype on almost every project since its inception, I decided to just roll out my own solution using the prototype library as a base. It turns out that the implementation was incredibly simple. I have attached a working example for your copy and paste pleasure. The javascript is incredibly simple. The entire javascript programming was less than 25 lines.

I fucked around with getting these bounding values so you don’t have to. I think you will find this useful if a client says to you, “now how do I jump to a state”. You will need the prototype library for this to work. I use it for element selection. If you know how to get the element in other ways then you likely don’t need me to tell you how to change this code. If you would like to download prototype click here.

make sure you include the prototype library before the code for you map.

First the select box that you will need somewhere on your UI

Select location Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware District of Columbia Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota Ohio Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming

The javascript you no doubt need, is the zoom to state code. It is basically a large switch statement with sensible latitudes and longitudes for zooming and centering. So here it is

So added 4 input fields, for name, email, subject, and message, and used those names as the instance names. then i put some labels in them, since i was planning on doing some nice ON_FOCUS text relacement. but before going much farther i needed to check to see if the alignment was right, and tested the movie.
At which point I quite unexpectedly got this error:

Error: Error #2078: The name property of a Timeline-placed object cannot be modified.
	at flash.display::DisplayObject/set name()
	at flash.display::Sprite/flash.display:Sprite::constructChildren()
	at flash.display::Sprite$iinit()
	at flash.display::MovieClip$iinit()


And I hadn’t even imported the form class I had used a dozen times before…

Solution

The Flash IDE has some reserved instance names stored in it that will give you immediate warnings when you try to use them (try entering name txt) name isn’t one of the reserved words, but—at least for input text fields—it should be.
Seems like they could have saved users some time and frustration by reserving that word in the IDE so that it can’t be entered.

It has a really good post about how he decided on the syntax for the bezier Tween. It also includes a terrific example that applies it to a Papervision3D camera object.

Also:

• For those not already familiar with Tweener there are some decent flas here.
• And some pretty neat tricks (especially tip 3) for the more experienced Tweenerers here.

Happy Tweenering.
