update_attrbutes without saving?
Hello all,

saving to the database? (the counterpart of update_attributes but

person.update_without_saving(params[:person]) #update the in-memory
object.
# Process person object
.......

[Bridge] Re: Bridge Digest, Vol 31, Issue 6
Hello
You must add first:
vlan (tagged) to eth2
eth2 interface is not tagged by default and not know vlan-s .

to this ports (tagged or untagged)
So you can compare that all interfaces in linux by default are in one
vlan(but not tagged). (only for

Hi,
When a IPSec tunnel is established between two peers, I understand that the
"normal" situation is to have in a given moment two SAs, one for each
direction of the tunnel.
However, in one of my tunnels (peer P1 running GNU/Linux with setkey and
racoon; peer P2 is a Cisco router) there is a large number (around 19) of
SAs established (this has been observed in P1 with

Linux router performance
Hi,
I wonder about the performance of a Linux box used as router (I guest I''m
not the first :). Althought I know it mainly depends on the hardware, I''m
trying to find some references on the topic or comparations with other
routing solutions (FreeBSD box used as router, Cisco, etc). For example,

Legacy Table works-except edit?

Why would I be able to show these fields in the show and list, but not

Fwd: ¿Cómo generar informes con R sin utilizar LaTeX?
Victor,
Me parece que podrías investigar si Scribus puede generar e insertar la
salida de R en sus documentos, por lo que estás agregando a tu pregunta me
parece que BI no es el camino. Si lo haces, creo que a más de uno en esta
lista le interesará la experiencia. La alternativa sugerida por Emilio

How might one write this better?
I am trying to simulate the trajectory of the pension assets of one

Conceptual Design Question
Hi All,
I am making a DAM (seems to be the hip thing to do these days). It is
for the company that I work for. We have some really weird domain

wanted to run it by you gurus to ensure that I am not recompiling the
