similar to: "humanizing" model attributes presentation

After searching arround I found a quite smart solution to me for binding form fields to model in an active way. I use aggregations with single value objects such as class Percentage attr_accessor :value def initialize(value) @value = (value.is_a? String) ? value.tr('' %'', '''').to_f : value end def to_s return unless value

This might be a problem with postgresql, but I''m not sure. In a migration I have renamed a table so I wanted to rename a sequencer as well. It looks like: execute "ALTER TABLE global_vacations_id_seq RENAME TO vacations_id_seq;" execute "ALTER TABLE vacations ALTER COLUMN id SET DEFAULT nextval(''vacations_id_seq''::regclass);" But the process of

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

Hi, I'm using rsync for a couple of things but I am at a point where I could not find a solution for my problem. this is what I want to do: rsync only the files i_* from a directory from machine A to machine Bi and delete them from machine B if they on longer exist on machine A. so I use the command: rsync -azv --stats -e ssh --delete i_* user@host:/dir/ When using this command the files

I have strange error that happens after couple of hours. Some instances start to respond on any request with status code 500. Log file unicorn.stderr.log gets populated with this error: app error: undefined method `each'' for nil:NilClass (NoMethodError) /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.1.2/lib/rack/utils.rb:267:in `initialize''

Dear R users, I have data on 4 types of interest rates. These rates evolve over time and across regions of countries . So for each type of interest rates I want to run a regression of rates on some other variables. So my regression for one type of interest rate will be I_{ij}_t= a +regressors +error term. where I_{ij}_t is the absolute difference in rates between two locations i and j at time

Hi, I would like to generate a correlation matrix with a particular structure. For example, a 3n x 3n matrix : A_(nxn) aI_(nxn) bI_(nxn) aI_(nxn) A_(nxn) cI_(nxn) aI_(nxn) cI_(nxn) A_(nxn) where - A_(nxn) is a *specified* symmetric, positive definite nxn matrix. - I_(nxn) is an identity matrix of order n - a, b, c are (any) real numbers Many attempts have been unsuccessful because a

Greetings, I would like to estimate a spectral coherence between two timeseries. The stats : spectrum() returns a coh matrix which estimates coherence (squared). A basic test which from which i expect near-zero coherence: x = rnorm(500) y = rnorm(500) xts = ts(x, frequency = 10) yts = ts(y, frequency = 10) gxy = spectrum( cbind( xts, yts ) ) plot( gxy $ freq, gxy $

I want to use ActiveRecord outside of Rails to do processing on large tables. I want to be able to process the rows as they are retrieved rather than having to store the results in an intermediate array. Any suggestions? Looks like I could hack the adapter to provide an accessor to the underlying DBI handle. Anything cleaner than that?

As soon as I use Model.find(:all, :include => [...], :limit => 3) I loose associations and can''t do :conditions on joined tables. I''m not able to do pagination in such association. Only solution I came up with is this beast: # I set up a paginator: @reos_pages = Paginator.new self, Reo.count(conds.join('' AND ''),

Here's the code and compilation steps: #include <stdint.h> typedef unsigned int uint128_t __attribute__((mode(TI))); typedef struct{ uint64_t l[5]; } s; void f(s * restrict r, const s * restrict x, const s * restrict y) { uint128_t t[5] = {0, 0, 0, 0, 0}; #define BODY(i,j) { int i_ = i < j ? i : j; int j_ = i < j ? j : i; uint128_t m = (uint128_t) x->l[i_] *

Hello, I'm starting to write a C function that gets a list and a matrix from R. I'm using .Call because I've undertood that this is recommended to handle lists (am I wrong?). My problem is that I can pass the matrix as a vector, but not as a 2D array. For example, in the following simple C program: #include <R.h> #include <Rdefines.h> SEXP printListElement(SEXP list,

One piece of code I'm writing has a lot of intermediates, and I'm trying to optimize down the number of memory accesses. Here's a snippet from the start of the function, where I think there is some low-hanging fruit: # BB#0: pushq %rbp pushq %r15 pushq %r14 pushq %r13 pushq %r12 pushq %rbx movq %rdx, %rcx movq %rdi, -16(%rsp) # 8-byte Spill movq (%rsi), %rdi movq

Hi, I have a few questions regarding copy and save_finish methods. How can I get a filename or processing mail from the parameters you get in that methods? How could I use the logger you use for dovecot inside my plugin? Thanks, Sebastjan -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I wanna modify Dovecot source code.For that,I need to know how can we log a special message into Dovecot source code? I tried to write a function to write a message in a file and added it to Dovecot source code,but it didn't work. I'm wondering if we can use Dovecote logging functions,but I don't know what are those functions and how can we use them. Thanks in advance. --
