extending rails via /lib - problems
I wanted to group some functions which I use in some models in one
place. Controllers have application.rb and views have helpers but I
couldn''t find anything about models. Using the /lib directory seemed to
be the only way.
Alright... so I have something like this:
/lib/code.rb
class ActiveRecord::Base
def method_a(n)
.......
end
def method_b(n)
........
end

Understanding when flash gets reset (render vs. redirect_to)
All,
I have a controller action that will do a different "render (:action)"
call
depending on whether or not data is valid.
When the data is invalid - I set a flash element to hold a message.
However, when I post back to this controller action and have valid data,
I still have the flash element set, which I don''t want.
I believe this is because I did a render from the

Setting up a local shared mailbox
One: I have never set up an IMAP server before, so I thought I would ask
first before blindly stumbling around. The problem I am want to solve is
this: my wife and I have a "joint" email account that we both want to access
(we also have our own personal accounts, but that's beside the point.) I
posed the question to my local LUG, and several suggested setting up a local

XEN or KVM - performance/stability/security?
Hi all.
I am currently building a small test cloud based on Eucalyptus 2.0.3 and
CentOS 5.8 x64. I have a choice which hypervisor to use: KVM or XEN.
KVM is the default in CentOS 6 but I have read also many good things (for
example PV guest machines, isolation between Dom0 and DomU) about XEN.
Key factors from my opint of view are:
- stability (which one runs more smoothly on CentOS?)

Virtualization - what do You recommend?
Hi All.
I plan to use virtualization in my production environment. I plan to use one
of the following options:
- KVM;
- VMWare Esxi;
- VMWare Workstation.
I plan to install Windows 2008 as a guest. I want to use something like LVM
snapshots for backups. Stability is also very important, the guest will be
used as a production server.
Which option could You recommend and why?
Thank You very much

NFS mount auto remount in case of problems.
Hi All.
I have a setup in which I have two servers serving nfs share. The nfs
service is made highly available with pacemaker. When the primary
server goes down the secondary starts nfs service. Service IP is
floating between servers but they have NO "shared" storage/filesystem
so NFS state/connection information in case of failover is lost. I
have two clients. When the failover from

Memcached - replication?
Hi all.
I am thinking about installing memcached with replication, I've found
http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but
it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not
want to use client side "replication" (writing to two memcached nodes at
the same time) and haven't found other solution.
Are there any good, protocol

Monitoring bandwidth, latency, packet drop.
Hi all.
I am currently thinking about monitoring a network link (bandwidth,
latency, packet drop). I have a centos server which is connected to
providers network through a switch. How to test the link? Should I:
- use ICMP to ping gateway and collect staistics of time/packet loss/etc.
- use software like here:
