How can you embed flash on a page and still have it validate?

asked by Dion Davis, a student in Phoenix

Maintaining page validation while embedding flash can be a pain for anyone. Most people try to drop the swf onto their page in dreamweaver, in this case dreamweaver will try its best to write a little code for you to make it work. The problem is that it doesn’t validate. In my opinion the easiest way to accomplish this is use the SWFObject JavaScript.

Is it possible to create a private variable in a Javascript “object”?

asked by Caustic Dave from Michigan

Private variables can be created by using the ‘var’ syntax before defining the variable.
That limits its scope to within the object it was created in.

Example

function fName(){
   //functions are objects in javascript
   var firstname = “steve”;
   // firstname is a private variable for the object fName 
}

lastname = “albridge” ;
// lastname is a global/public variable

Firefox has become the defacto standard for web developers across the globe. Through easily available extensions it is a indisposable tool for professional web workers.I didnt realise how much of my productivity was tied into firefox until my Mac went bust and I had to re-install firefox. Like all developers, over time I had accumulated quite a few nifty time-saving Firefox Extensions and bookmarklets like The Web Developer Toolbar, ColorZilla color picker, Firebug debug console and the Tiny HTML validator.

My Fresh Install of firefox was lacking all these extensions and i spent quite a bit of time finding and installing them again and syncing my bookmarks [ which existed across Foxmarks and Delicious ] only to find that I had neglected to manually backup my saved passwords, Having being born with the attention span of a goldfish i struggle to manage passwords and ids across multiple websites, so the loss of my auto-filled passwords had made life hell.

Hoping to avoid this scramble next time around I decided to investigate the various options available for backing up firefox profiles.
