O''Reilly Rails Cookbook on Rough Cuts
Subject says it all. Anybody taken a look yet?
http://www.oreilly.com/catalog/railsckbk/?CMP=ILC-GG7423313304&ATT=railsckbk
After buying the Ruby Cookbook and the other Rails book, I''m pretty
gunshy about another Rough Cuts purchase.

Better way of writing R code
Dear R forum,
(Pl note this is not a finance problem)
I have two data.frames as
currency_df = data.frame(current_date = c("3/4/2013", "3/4/2013", "3/4/2013", "3/4/2013"), issue_date = c("27/11/2012", "9/12/2012", "14/01/2013", "28/02/2013"), maturity_date = c("27/04/2013", "3/5/2013",

o''reilly''s arrogance
although basically hopeful of the company''s ''rough cuts'' venture, i am
insulted by the fact that o''reilly''s safari service offers important material
to its regular subscribers only if they pay extra for it. o''reilly''s material
on ajax is a good example: all of the introductory coverage is available only

extra digits added to data
I am having a problem with extra digits being added to my data which I think
is a result of how I am converting my data.frame data to xts.
I see the same issue in R v2.13.1 and RStudio version 0.94.106.
I am loading historical foreign exchange data in via csv files or from a sql
server database. In both cases there are no extra digits and the original
data looks like the following:

Instiki @ O''Reilly ETech 2005
Hi all,
Sorry if I should be posting this elsewhere--I couldn''t find an
Instiki specific mailing list, but the Instiki site is down.
I wanted to mention that my friend Tim Lauer and I are going to be
doing a short "high order bit" talk at the O''Reilly Emerging
Technologies conference, describing a particular use of Instiki which
we came up with:

[OT] O''Reilly Cookbooks
Hi,
Has anyone gotten the "roughcuts" of the Ruby and Rails cookbooks? If you have the Pragmattic Rails Cookbook is the O''Reilly worth it? Also can you download PDF''s of their "roughcuts". The website is kind of vague, it just mentions online access (whatever that means).
Thanks in advance.

Naive suggestions for (kinda) funding
First of all, don't shoot me if I got some things wrong.
I personally recommend (without much success :-)) to buy from www.cheeplinux.com (Definite Software), because I believe this is of some help to the CentOS project. At least, to some people involved in it (please correct me if I'm wrong).

How to read or write Geolocation (RFC6442) data in SIP/PJSIP messages ?
Hello,
I'm having a look at section 13.1 from SIP Connect v2 doc (see [1]).
It refers to RFC6442 which gives the following example (sorry for its
length):

Ruby at O''Reilly Rough Cuts
Not sure if this is old news or not, but it would appear that both the
Ruby Cookbook and a Rails book are now available for purchase at
O''Reilly Rough Cuts (something akin to PragProg''s beta book program):
http://rubyurl.com/nHz
http://my.safaribooksonline.com/?mode=roughcuts&srchtext=ROUGHCUTS
I haven''t tried them yet, but it definitely seems worth checking out.

exception_notification plugin not sending mails in development on localhost
Hi everyone,
So, I''ve got exception_notification working now, but not in
development mode on localhost. In my ApplicationController, I''ve
added:
local_addresses.clear
Shouldn''t that be enough?
Thank you!

Model.find(:all) where Model.association has more then 0 items?
Hi everyone,
I have a Department model that has_many people. How do I go about
finding all departments with more than 0 people?
Department.find(:all, :conditions => Department.people.size > 0)
That, of course, doesn''t work, but it was as close as I could come.
Thanks!

No.
It also is an artifact of code compiling architecture and OS dependent
features based on what they detect at configure time
It is an artifact of compiling non-type

I made some progress on my previous "systemfit" question but still not quite there
Surprisingly, I played around with some test code and below actually
creates equations that look correct.

restrictmat<-diag(6)
colnames(tempmat)<-c("AUD.l1","CHF.l1","CAD.l1","GBP.l1","EUR.l1","JPY.l

multivariate xts merge question
Hi,
I have an xts starting with a number of columns (currency pairs see below),
then I add new ones which are derived from existing ones (like adding the
moving average of a column) by merging the new columns one by one. These
get the name of the column they are calculated from concatenated with ".1".
All done by merge.xts, easy.
Now, I have a function (procState below) which generates

MySQL in dev, Postgres in prod - differences in "LIKE" query
Hi everyone,
I run MySQL in my dev environment, but Postgres in my production
environment (out of necessity). I''m having trouble finding a way to
write a query with a LIKE condition that is supported as case
insensitive in both databases.
Right now, I have this:
@query = "m" # for example
@people = Person.find(:all, :conditions => ["last_name LIKE ?", @query +
