I have an arbitrary program written in any language, and it is a binary (ie foo.exe), that will print out output to stdout constantly every 3-5 seconds. Is there a way that I can have a web application designed in rails that will print the output of this program to the browser every 3-5 seconds in realtime, preferably even in an ajax manner. thanks -- Posted via http://www.ruby-forum.com/.

Is there some way to tail -f a file and print whatever tail -f gets to the browser on the client side. I''m thinking periodically call remote can do it.

I am using periodically call remote on a page to do an action similar to top on unix. I would like this periodically call remote to act on milliseconds and not seconds. Is there a way for it to go faster than 1 second frequency or is that the fastest? Also, is there a better way of doing this than sending ajax calls every second because it does seem kind of messy.

How do you push a client? For example, how does www.meebo.com know when someone sends an IM to you and send that to your browser. Using firebug, I noticed they do only have a periodic check of 30 seconds. They do not really have something polling every 1 second. Do they open a port on your computer when you log in , so your computer acts as a listening server? Thanks -- Posted via

How would you change your session key when you open a new tab. Say I''m in firefox, and I have a tab opened. I have a session key holding the session variable ''test''. When I open another tab, they will share the same session key , and if I modify test on that new tab, it will affect the old tab. Is there a way to change the session key this new tab uses? Thank
