JSON is a universal data format. It provides an uncommonly effective bridge for moving data between systems and between languages. It is rendering the X in AJAX superfluous. JSON is also really simple. This talk will spend several seconds to fully explain the entire JSON language. There will also be a first look at a new JSON solution to the Cross Domain Problem. ...

Discoverer of JSON Recommends Suspension of HTML5

"There is much that is attractive about HTML5," says Douglas Crockford, known to millions of developers as the discoverer of JSON (JavaScript Object Notation), the widely used lightweight data-interchange format.

JavaScript’s objects are soft and currently the language does not include any means to harden them, so an attacker can easily access the fields directly and replace the methods with his own. Fortunately, JavaScript provides the means to construct durable objects that can perfectly guard their state by using a variation of the Modul... (more)

Douglas Crockford's Blog DRM is sometimes called an enabling technology, in that it is supposed to enable new business models. But it is really a disabling technology. As DRM fails, there have been suggestions that the name be changed to something that includes the word enabling; give it a better image; something more right than rights. DRM isn't just a disabling technology, it is also a disabling contractual framework. To sell a DVD device, you must make a deal with the DVD Copy Control Association in order to use the CSS copy protection system that was broken nine years ago. ... (more)
