Hi Devs, Consider below testcase. $cat test.cpp #include <vector> #include<type_traits> typedef int _int4 __attribute__((vector_size(16))); typedef union{ int data[4]; struct {int x, y, z, w;}; _int4 vec; } int4; typedef int4 int3; int main() { static_assert(std::alignment_of<int4>::value <= alignof(max_align_t), "over aligned!"); } $clang++ -m32 error:

Hello r users, I have to deal with int8 data with R. AFAIK R does only handle int4 with `as.integer` function [1]. I wonder: 1. what is the better approach to handle int8 ? `as.character` ? `as.numeric` ? 2. is there any plan to handle int8 in the future ? As you might know, int4 is to small to deal with earth population right now. Thanks for you ideas, int8 eg: human_id

I''m interested in working on a message board application that uses ruby on rails. I''d like to see something end up similar to vBullieten, but with more of a 37signals type of less-is-more philosophy... mostly meaning less need for preferences and settings and configurations. I''ve checked rubyforge, and it looks like there are various forum apps uploaded there, some

I ran into this issue too. My solution was to add an "onUpdate" function to the sortable that tests the container to see if it''s got any children or not: function is_empty(container) { if ($(container).hasChildNodes()) { Element.removeClassName($(container),''empty''); } else if (!$(container).hasChildNodes()) {

Hi, I''m getting the error below, and I''m not sure where to find "acts_as_list" ...

So I seem to be having an issue with trying to install acts_as_list in rails 2.2.2?

I got it to work by changing scheduled_end_date= nil to self.scheduled_end_date= nil. I believe these statements should be equivilent. I don''t know Ruby/Rails well enough to know when, if or why that should matter. Can someone educate me please? I want to believe this framework is ready for production work, but silently dropping data is a very big problem. I expect that I''ve

Hi ! There must be something I don''t understand clearly in acts_as_list I have a list of gallery entries (images + text), model is GalleryEntry.

Well I definitely cannot use them as numeric because join is the main reason of those identifiers. About int64 and bit64 packages, it's not a solution, because I am releasing a dataset for external users. I cannot ask them to install a package in order to exploit them. I have to be very carefull when releasing the data. If a user just use read.csv functions, they by default cast the

Hi, How are people specifying models which act_as_list? I''m thinking that it would be possible to check that acts_as_list instance methods have been added to a class using something like this: describe Page, "acts_as_list" do it "should act as a list" do Page.ancestors.should be_include(ActiveRecord::Acts::List::InstanceMethods) end it "should use

in a single table inheritance model, rails will automatically set the scope for acts_as_list to the ''type'' field as well as any other scope conditions we provide. Is there a way to disable this? i want to use STI but I want acts_as_list to disregard the class type when getting/setting positions. thanks alan

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

The files are in my vendor/plugins/acts_as_list folder so I have: lib/active_record/acts/list.rb

Right, they are identifiers. Storing them as String has drawbacks: - huge to store in memory - slow to process - huge to index (by eg data.table columns indexes) Why not storing them as numeric ?
