I'm not going to talk about a star cluster obviously, (although I'd like that :) ) but about a server cluster. Basically we're talking about a bunch of servers that work together to perform certain tasks.

These tasks can vary from doing file operations, running databases, to doing some sort of complex math calculations.

If you upgrade from php4 to php5 you'll see the following error when you're trying to save png files.

gd-png: fatal libpng error: zlib error

The thing is that in php5, the quality range changes for imagePNG from 0-99 to 0-9. therefore you need to change your code to relect this, e.g.

imagepng('','', 9);

This is a small tutorial on how to use embedded fonts in the library with Actionscript 3.0 / 2.0.

You have to follow the next 4 steps to correctly embed and use library fonts in your code.

1. Add the font to the library - right click the library panel and select 'New Font'. From the 'Font' drop down select the font you want to embed and give it a name in the 'Name' field. The name can be the same with the font.
