So, repetition is the mother of all learning they say. You damn right it is. And you can do it in AS3 of course. Not the fastest choice out there but that’s not the point. NN’s are usually not that fast but they’re useful in so many ways.

So, here is my implementation of a neural network multi-layer-perceptron made in AS3, set to learn a simple XOR problem. It uses 2 inputs neurons , 2 hidden layers, each having 2 neurons and one output neuron. It takes about 2 seconds to train it using 10.000 epochs, but then you can save a snapshot of the NN memory as a byteArray, save it to the server and load it back again in an instant without requiring a new training.  I didn’t take the time to thoroughly document the classes just yet but I’m sure you’ll find them pretty easy to use.

I’ve joined the campaign to end IE6 for quite a while now. My page even showed in black and white if viewed in IE6 (for nostalgic users) but seems a campaign or hundreds of them are not enough to solve this.  Seems you can win this battle with politics and technical arguments. You need a revolution.

So from now on, my site (and any website I will build) will not display to IE6 users.  They don’t need logos advising them to let the web evolve, or hear about the pain of the developers. No! They need brute force. If the web won’t work they must change their browsers. How can we convert those 20% other way ? I say fuck’em!

Viva La Revolución

In case this happens follow these steps:

1. Extract the runjettyrun_1.0.1.jar in the eclipse plugin directory
2. Extract the jetty-6.1.6.jar in the lib directory of the previous jar.
3. Edit the file org\mortbay\jetty\webapp\webdefault.xml and change the “useFileMappedBuffer” to false. It should look like the following:

1
2
3
4

<init -param>
      <param -name>useFileMappedBuffer</param>
      <param -value>false</param>
</init>

4. Pack everything back up and overwrite the runjettyrun jar in the plugin directory.
5. If you still get the error after step 4 start eclipse.exe with -clean and then recreate the Jetty configuration. (It just need to replace whatever jar’s it copies in your workspace .plugins dir)

If you have a problem with quotes in Windows 7, try to switch the keyboard layout from “United States – International” to “US”

After installing Windows 7, I discovered the following behavior in the code editor: Pressing the quote (‘) or double-quote (“) key once would have no effect. Pressing any key after that would produce both the double quote character and the next character.

The problem is caused but by regional settings – I solved it by switching from “United States – International” to “US” keyboard layout.

Go to Control Panel->Region and Language->Keyboards and Languages tab->click Change keyboards… where you add English (United States) – Us to the list and then select it as default from the top drop down list.

It’s a work in progress but curently I’ve made codecs for the following formats:

• PointLineCAD 3D objects (*.p3d)
• Photoshop images (*.psd, *.pdd)
• ZSoft images (*.pcx)
• Truevision TGA (*.tga, *. icb, *.vda, *.vst, *.win)
• Windows icon files (*.ico)
• GIF images (*.gif – static and animated gifs)
• JPEG images (*.jpg. *.jpeg, *.gfif)
• PNG (Portable network graphic) images (*.png)
• Windows Bitmap images ( *.bmp, *.rle, *.dib)
• Adobe Shockwave Flash (*.swf)

As I said before, the way you provide the source doesn’t really matter. You can zip up all your images in an archive and as source you can just point to the file inside the zip.

1

<adm :ExtendedImage id="img" source="archive.zip://image.png" />

This way, you greatly reduce the number of requests to the server. But this is not all. Source can be also provided as a base64 encoded string, or as plain text (only p3d can take advantage of this since the p3d file is plain text as well).
