Real-Time Push ::: RE: vancouver ruby on rails conference

[Colm Toolan]

Steve,

There have been many versions of push over of years. I was involved in
Slingshot from CSK Software '96 thru' '99. Once you get past "pull
masquerading as push", all of the solutions are similar to some extent.

I like the Lightstreamer stuff because it's "streaming Ajax", which is nice
for the Ruby on Rails fans and because it looks like a fairly professional
packaging product.

But then I'm not a techie - or hadn't you guessed? :-)

Just van de Broecke has been demonstrating what he calls "pushlets" since
about 1998. Is it any different?
