Facebook has chat application launched, Not yet seen, check them out now. When you log in, you will see the pop up notification.
I just recently known there is a technology call Comet on the server side. which is really incredible. So what it basically does is: it is able to push the data to client side (browser) when there is update, which means you dont have to refresh the page to see the update or so. My guess is the facebook implements some kind of server technology like this to get their chat application running.
And as mentioned by the article in Wikipedia I gave the link above (UP THERE), it needs a lot of servers to make them works smoothly especailly for a busy site like Facebook. Ha, seems Facebook are working hard to push the possibility to the limit.
As I mentioned in last article I wrote, developer position will become more difficult to get, but I think it over, if we focus on the technology, and keep pushing the technology to the threshold, which in turn will require other business to keep up with the tech. and so, it creates the needs for more developers.
So it is just your choice of being a good or bad programmer, as well as having wonderful or stressful career. I think it applies to every kind of industry. Focus on what you doing, and keep doing it the best, I suggest.
