Help me deliver these videos to you faster!

Editing and compressing h.264 video for screencasts has become insanely expensive in terms of time. A 40 minute 720p video can take up to four or more hours on the final compression. My goal is to be able to deliver these videos to you faster, but I need your help! Please donate any amount to help me purchase faster hardware, allowing me to deliver videos faster to you.

Hi Jay,

Thanks for your tutorials, they are very good.
I want to ask you if you can speak about separating of files in javascript or Ext, because after we have much code in a single file it’s hard to understand.
And also another question. I didn’t understood exactly how Panels and Layouts work. Is this like in swing you have a panel and a layout for this panel, or not, because sometime when I put a grid in a panel which has a layout he makes to not appear anything from all code, and firebug or safari developer doesn’t complain about errors.
Thanks again and have a nice day.

Regards
Jay Garcia

Hi Zavos,

The separation of files can be done in many ways. The important thing is organization of your classes in namespaces.

Panels are extensions of containers, which can contain children, and add things like toolbar support, etc.

Layouts are tools that Containers use to visually organize child items on the screen. Have you considered looking at Ext JS in action? It is well elaborated on there.

Ext JS Screencast #008 will focus on other layouts

I am really pleased to see some screencasts about ExtJS, even happier to see that they are very visual! Keep up the great work!!
