Hi everyone, I''ve been playing around with the Globalize plugin for some days now but I can''t seem to make it work properly with my models. I''m currently using Postgres 8.0 for the database and needed to make some modifications with my migration file that was posted by Jake Morrison in the Globalize wiki...

I''m trying to figure out how to change the order of a list view and it''s obvious to me that I don''t understand what I get from a simple scaffold to know enough to alter it. If someone would be so kind to tell me what this means ... def list @placment_pages, @placements = paginate :placements, :per_page => 10 end @placement_pages, # I am guessing that this

I have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

Hi, I''m coding a little application to make couples profile. The problem is I just don''t know how to create my databases so that their are no bottlenecks and that I can have a relation. The way I see it is that their would be a user database and a profile database and they would link 2 to 1. Is this the right way? In the user db I would store their userid and some session info,

I am using getSymbols function from quantmod package to get price data from internet. Currently I have: my.ticker <- "IBM" getSymbols(my.ticker,src="google") This creates an xts object named my.ticker which contains historical price data for IBM. How can I call and manipulating this xts object using my original string my.ticker? I want to do: colnames(my.ticker) <-

Hi Yin, I second David's words. I use shared libs myself on debug builds, but static builds with gold on a local disk is pretty feasible. Before I used gold, I had to have 16GB of RAM on my laptop, now I need less than 8GB for static builds. On 28 January 2016 at 23:58, Yin Ma via cfe-dev <cfe-dev at lists.llvm.org> wrote: > It is O.K.

Hi John, It seems the dereferencing a NULL pointer is undefined behavior but Calling a function through a null pointer seems o.k. If so , for this place, we need comment out the check. http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#232 look at Notes from the October 2003 meeting.

The summary stats for the xin and yin variables below are correct. However, if I use plot(xin,yin), an exception is thrown saying that "object xin is not found." Also, it is apparent that I can't successfully replace the x and y vectors with values from xin and yin. The four plots on one panel are showing but the range of x and y is only [0,1], and therefore, it seems like an

i need to find the best ticker from the group of some tickers.? i also need to know on what basis we calculate the best ticker? i have some idea about the if the risk rate low, or the market price high we can say the ticker is best. but i dont know is it true. Anyone can help me . Thank you -- View this message in context:

Hi, For a small case, that calls NULL pointer function. LLVM explicitly converts It to a store because it thinks it is not reachable like calling undefvalue. In InstCombineCalls.cpp:930 I think it is not a right approach because calling null pointer function Will segfault the program. Converting to a store will make program pass Silently. This changes the behavior of a program.

Hi Duncan, To use select, usually, there is a compare before select. Presence of comparison will disable some opportunities to optimize some code. Select and Compare is not associative neither.

Hi, I have what I think is an easy question. I have a data frame, called stockdata, of stock prices that looks like this: date ticker close 1 01/02/1998 GE 24.667 2 01/05/1998 GE 25.104 3 01/06/1998 GE 24.771 4 01/07/1998 GE 24.979 5 01/08/1998 GE 24.750 6 01/02/1998 HIT 71.125 7 01/05/1998 HIT 72.313
