graphics site
About six months ago there was a reference to a site (in french) that
did a spectacular job of demonstrating R's graphical capabilities.
My bookmarks were recently wiped and I cannot find this site despite my
best googling.
Anyone have the address which I have done a miserable job describing?
Thanks.

Snom firmwares suck <--additional datapoint to consider
We have a large install of 360's running rev 4.1 with zero problems. I did
another, smaller install couple weeks ago with 40 360's running rev 5.3. In
both cases, the install was identical, same Asterisk version, same dialplan,
everything the same except the differences were:
1. Different firmware rev
2. Different physical LAN
Guess what? On the smaller install, lockups and reboots.

React on select_tag (onchange)
Hi,
I''m new in developint rails (but I love rails).
I would like to react on changing a field in the view (no model field)
from a selection box to show the number of rows (which I used in the
controller).
In the controller I read the params-hash:

@rowsperpage = params[''rowsperpage''].to_i

In the view I have the field, where I like to react directly.

IPSec tunnel
Hi!
I''m testing IPSec tunnels, having the following test schemma:
Host A - eth0: 192.168.1.67
eth1: 192.168.10.1
Host B - eth0: 192.168.1.254
eth1: 192.168.20.1
I''ve succesfully configured an IPSec tunnel in order to safely
communicate from 192.168.10.0/24 (which is obviously behind Host A), and
192.168.20.0/24 (obviously behind Host B)
