"So what is an “augmented reality catalog”? Apparently you’ll be able to take your phone, point it toward a piece of furniture in the catalog, and see an “X-ray” depiction of the unit. So you’ll get to see what holds the furniture together, but it will also be augmented with links to video clips, 3D models, and digital how-to guides. The paper Ikea catalog isn’t going away anytime soon, but the retailer said it really wanted to bring some digital interaction to it."
HTTP has been the most successful application protocol ever invented, by a wide margin.
“SPDY” is a drop-in replacement for HTTP networking that
should be invisible to both clients and servers.
It was cooked up at Google, and is built into Chrome and Firefox,
and a lot of the servers at Google use it.
Mike Belshe, who’s sort of seen as the guy behind SPDY,
used to work for Google but doesn’t any more."
SPDY does not replace HTTP; it modifies the way HTTP requests and responses are sent over the wire. This means that all existing server-side applications can be used without modification if a SPDY-compatible translation layer is put in place. When sent over SPDY, HTTP requests are processed, tokenized, simplified and compressed. For example, each SPDY endpoint keeps track of which headers have been sent in the past requests and can avoid resending the headers that have not changed; those that must be sent are sent compressed.
