Pragmatic Studio''s Advanced Ruby training is coming up next month (early registration ends soon!), and folks often ask what to expect in our advanced classes. You might also be wondering how Rails developers will benefit from attending this public class. So I asked Dave Thomas and Chad Fowler (the instructors) to share a few of their thoughts on the Advanced Ruby class in this short

I was looking at Justin Gehtland''s blog. There are instructions on getting started with Streamlined, however gems returned an error that streamlined was not in the repository. I guess Justin is putting the preparations down ? Stuart

Hi Folks - Just a quick reminder before the end of the year... We have a new Ruby Studio coming up on February 27-29th, taught by Dave Thomas and Chad Fowler.

In two weeks, Dave Thomas will be in Pasadena doing a three-day Rails workshop. I''m about to sign up for it. I figure three intense days with Dave and a few dozen other Rails developers will produce huge learning leaps for me. Then it occurred to me that it might be useful to ask the list if anyone has attended one of these workshops before and, if so, how valuable you found

Hello I'm trying to make survival curves for some longevity data - 100 males and 100 females, some of which are still living (not dead at the end of survey) I would like to make sex specific survival curves as time on the X axis, proportion alive on the Y, and a line for each sex (two lines) Data looks like this: Focal DOB DOD Longevity Sex 1 89-04-20 na

Hi all, I have a dataset consisting of 5 columns and over 5000 rows. Each row gives information about an individual animal, including longevity, i.e. at what age an animal died. For the model I use I need to create n rows for each animal, n being its longevity, and a new column 'survival' with a binary 0/1 outcome. When an animal died e.g. at age 5, there have to be 5 rows of identical

Can survreg() handle interval-censored data like the documentation says? I ask because the command: survreg(Surv(start, stop, event) ~ 1, data = heart) fails with the error message Invalid survival type yet the documentation for Surv() states: "Presently, the only methods allowing interval censored data are the parametric models computed by 'survreg'"

I''ve uploaded the B1.12 version of AWDwR. The major changes include: - Justin Gehtland''s new chapter on Web 2.0 - James Duncan Davisdon''s chapter on deployment (this is an interesting one---JDD has strong opinions on how a Rails application should be deployed, and the chapter mirrors this. You''ll find it short and easy to follow). - I changed the

The following code snippet allows you to update multiple DOM elements in a single Ajax call in Rails (1.1): # pass in a hash of domid=>template name def update_many(options) render :update do |page| options.each do |k,v| page.replace_html k, render(:partial=>v) page.visual_effect :highlight, k end end end So, if you wanted to update the

Hello, Say I want to make a multiple regression model with the following expression: lm(y~x1 + x2 + x3 + ... + x_n,data=mydata) It gets boring to type in the whole independent variables, in this case x_i. Is there any simple way to do the metaprogramming for this? (There are different cases where the names of the independent variables might sometimes have apparent patterns or not)

Our Mephisto install kills Mongrels and causes Apache to pound the CPU. This started when we moved to Apache+mod_proxy_balancer+Mongrel. Here''s what we know: The following things are working OK, except when used in the combination listed above: mongrel, mongrel_rails, MySQL, Apache, mod_proxy_balancer. We believe these are all OK because we moved five other Rails apps to this

Does BTRFS perform any journal and/or filesystem structure alignment (for benefit to SSD longevity and SSD, RAID array and large-sector device performance) at present? ext4''s Ted Tso will deliver 128KB alignment with the next release of e2fsprogs (ie 1.41.4) [1], so perhaps it''s a good idea for btrfsprogs also, if not already available? Daniel --- [1]

i'm sure there's a simple answer to this -- i already understand that newer kernels than the ones shipped with the official release aren't officially supported but there is the elrepo kernel repository here: http://elrepo.org/linux/kernel/el7/x86_64/RPMS/ with a mixture of long-term (lt) and mainline (ml) kernels. i assume that the mainline kernels pretty closely track the latest
