Nolan, I agree with you, Java is a GREAT language. Even MS admits
major programmer productivity gains (vs. C++). My problem with Rod
is that I think Java belongs on the server and not on the client.
Rod seems to think that Sun's server biz is going to die unless
Java clients are a success, which to me is the wrong of looking at this.

But in a previous post
--- you said ----
Well then, enlighten me!!!
You keep saying Java is great, but you are not giving very many
reasons why. So far, the only reason you have mentioned is because
you feel that java will reduce trafic between client and server,
which I disagree with. If you have other reasons written in
another post, then just provide the link.
-----------------------
that sounds like a contradiction to me, but never the less, I'll bite.
What is the network traffic for a simple MouseDrag...
Dumb X-Terminal:
----------
Every mouse move has to be sent to verify if it crossed
over a boundary into a place you're interested in. If so
you have to send back the icon image to display over that
area.
Java/NC
-------
ZERO!
all events are handled locally and only if you do something
like actually drop the object and it has to fetch objects
from the server is there ANY network traffic.
Reduction???
------------
For openers just count how many pixels you cursor crossed over
and multiply that by about 64 bytes (Probably more depending on the
packet size of your network) and that give you a *SMALL* idea
of how much you save.
More examples???
---------------
A simple button press: send one image to show a
selected Icon, another to show the unselected icon.
Window moves: the WHOLE WINDOW IMAGE for each mouse location.
Iconifiy/DeIconify window: ....
Well you get the picture (well, maybe if you're on a X-Term
you'll have to wait till someone quits moving the mouse.. |
