Behavior of first_or_create
I just ran across a weird glitch (IMHO) in find_or_create. The arguments passed to it are *not* added to the conditions for the ''first'' part. This is odd, given that it''s intended to replace find_or_create_by_* methods, which *did* use the specified values as conditions.
I''m unsure on whether this behavior is entirely undesirable, but it''s definitely

one master table to hold symbols: good or bad idea?
(This is may be more of a db design question than a rails question.)
Summary:
I''m thinking of creating a single AR class to hold constant symbol
values and use it for :has_many_through relations whenever I need a
constant symbol. Is this a good idea or a bad idea?
Details:
I notice that I have a lot of models that contain just a name string:

DAHDI/ZAP overlap dialing
Hi,
I have a PRI euroisdn link between an Alcatel PBX and Asterisk.
I'm having some trouble with overlap dialing.
Suppose I dial '874053' from an Alcatel extension ('7034') where '87' is an Alcatel prefix of type "ARS Prof.Trg Grp Seiz.with overlap".
I'm expecting Asterisk to receive '1004053' (where '100' is a prefix which always shows

Uniqueness and sql serialize
Hi fellow programmers,
I was looking for how to keep integrity in some financial transactions and
I saw this "This could even happen if you use transactions with the
‘serializable’ isolation level." in the uniqueness page

How this is possible with the serializablo

Rescuing Overwritten Pools
Hi All,
I have a usb drive (80gb) that was formatted as zfs and had my music
collection on it when I inadvertently used a bug in freenas to recreate as
a new zfs volume which no longer seems to contain my music. It used the
80gb rather then the clean 2Tb that I intended it to use.
The overwrite is not catastrophic as the drive only contained the FLAC rips
of my own music collection,

Rescuing svn repo from *IDIOTS*
Hello,
A moron has checked in a DVD iso into subversion.
How can I undo the damage, and make the repo a sensible size again?
Also, is there a cunning way to get subversion to say: "Oi! Moron!
This file is huge, you can't check it in!" ?

Rescuing from REXML::ParseException
Hello,
When I call an action with some invalid XML or JSON data a parse
exception gets raised from within Rails/Ruby (REXML or
ActiveSupport::JSON). The problem that I''ve got is how to handle these
exceptions. In my application_controller.rb I have the following for
debugging purposes:

SELinux and daemons - clever way to change default locations?
I'm sure you've seen this before:
You need to slightly tweak the default installation of a major daemon -
let's say you're running a big MySQL database and you need to put it on
a different filesystem, mounted (for example) as /db
So you move /var/lib/mysql to /db/mysql (and preserve all the file
attributes, including SELinux), change /etc/my.cnf accordingly, start
mysqld -

Too clever for my own good.
I just spent a couple of hours trying to track down a maddening tricky
problem.
Here''s the backstory...
I''m developing in OSX using locomotive and rails 1.1.2
My application suddently started behaving very inconsistently. I would
go to a controller and the first time I went there, everything would
work fine. If I refreshed, or hit another action, I would start getting

Wine or AOL being so clever?
Just installed Aim for win 98 using Wine, and it ended up putting a nice
Aim icon on my KDE desktop with the wine command in to start aim - i.e.
wine "/mnt/win98/Pro...."
This is getting really smooth!

Is there a clever way to page a group of extensions?
I want to be able to dial a 'pager' extension from an phone on my
asterisk server, and have it ring all other extensions *except* the
extension from which I am calling (because call waiting is enabled on
most extensions by default) - effectively giving me the ability to
page all other extensions from any phone. The solutions I've come up
with so far (individual contexts for each

Who has the clever Polycom upgrade system?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I remember someone wrote a great document concerning Polycom server
provisioning that provided a way to ensure that updates to the firmware
did not overwrite customizations. I'll be damned if I can remember
where I saw it. It may have been discussed during a VUC session or may
have been on this list.
Either way, I'm unable to google my way

clever ways to "share" an extension between sip and fxs
Using Asterisk 1.6.1.9, I'm looking for a way to "share an extension"
between a SIP phone (Cisco 7940) and a SLT on a FXS port of a Cisco 1760
(via sip) -- at any given time I want to be able to pick up either phone
and it should be "bridged" to the other - just like having two SLTs on the
same copper pair.
The goal is to have a cheap cordless telephone sit right next

Clever R syntax for extracting a subset of observations
I know that if:
x = seq(1,10)
d = c(7,3,2)
and if I say
y = x[d]
then I get the vector y as (7,3,2). Very clever! This idea is used
intensively with the boot library.
Now consider the following code (which works):
---------------------------------------------------------------------------
library(boot)
sdratio <- function(D, d) {
return(sd(D$x[d])/sd(D$y[d]))

how to be clever with princomp?
Hi all,
I have been using princomp() recently, its very useful indeed, but I have
a question about how to specify the rows of data you want it to choose.
I have a set of variables relating to bird characteristics and I have been
using princomp to produce PC scores from these.
However since I have multiple duplicate entries per individual (each bird
had a varying number of chicks), I only want
