Is it possible that the iPhone can somehow send data or some control command to the computer's com ports via USB cable? Maybe use inline assembly language for instance? Thanks!
When you speak to your colleagues or you want to convince your client to use Coldfusion for some new project and not some other technology or language they heard of before, which arguments do you use?
I'm asking because I'd like to make presentation to put in my company's portfolio and seems that I can't find any real life, non development kind of arguments. Yes, cfquery and cffunction access="remote" make our lives easier, but client doesn't care too much about us, right?
Language : C++

I have an exe calling a DLL, in which when I allocate (new) the memory for class A (which is in DLL) it returns me a non-local heap pointer.
I try to new other classes which are in DLL and "new" returns a valid heap pointer for them, its only Class A which is not being allocated properly.
I am on windows and validating the heap by this function call :
_CrtIsValidHeapPointer ( (const void *) pPtr )
I am seriously confused why this only happens with new-ing Class A and no other class ?

For those of you who are into programming not just for the money. I would like to know which benefits you would like to have (or already have).
OK, maybe taking away the money factor will limit this question too much. I am surprised to see that most companies have a fixed set for their benefits package. Were you able to negotiate something new or just your salary? What things have you seen out there and/or value most?
I am not sure what language or how to do this, but I am looking to have a word on a page, and when clicked, it will reveal more underneath. If it is clicked again, that stuff will hide away again? Any ideas?

Hi,
I have some PHP code that sends a section of html code including some inline Javascript code by curl to google. When i get it back from Google translated into the language that i chose, the Javascript code has been translated too.
Any ideas as to how i can stop Google translating my inline JavaScript code?
Thanks,

We are programming a new web application framework (Second WAF). I was wondering if we should support cookieless sessions or not.
Who use it and who needs it?
I've got several pre-commit hooks that I would like to run before each commit. Right now, they are all just shell-scripts, so I know i could just concatenate them to get them all to run. In the future though, additional scripts may be written in Perl, PHP, or some other language as well.
How can I run several different scripts as part of a single pre-commit hook?
I'm trying to find out what a binormal is in the context of graphics programming but coming up short, I saw on a site that the binormal was being calculated as the corss between the normal and tangent (i.e. cross(normal, tangent)), is this the correct way to calculate a binormal?
I am following the BigNerdRanch iOS Programming book and I am on this one chapter that deals with UITableViewController. I have been wondering however where UITableViewController finds out about its delegate and dataSource. Currently I have it as
@interface ItemsViewController : UITableViewController <UITableViewDataSource, UITableViewDelegate>
But there is nothing that looks like:
[self.tableView setDelegate:self]
I am just wondering how the UITableViewController finds out about its delegate and dataSource
how does this work?
in irb:
>> class A
>> b = [1, 2,3]
>> end
=> [1, 2, 3]
Is b an instance variable? class variable? how would I access b from
outside the class? Is it used for meta-programming?
Hello everyone,
I'm using the rails-settings gem, and I'm trying to understand how you add functions to ActiveRecord classes (I'm building my own library for card games), and I noticed that this gem uses one of the Meta-programming techniques to add the function to the ActiveRecord::Base class (I'm far from Meta-programming master in ruby, but I'm trying to learn it)
module RailsSettings
class Railtie < Rails::Railtie
initializer 'rails_settings.initialize', :after => :after_initialize do
Railtie.extend_active_record
end
end
class Railtie
def self.extend_active_record
ActiveRecord::Base.class_eval do
def self.has_settings
class_eval do
def settings
RailsSettings::ScopedSettings.for_thing(self)
end
scope :with_settings, :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}')",
:select => "DISTINCT #{self.table_name}.*"
scope :with_settings_for, lambda { |var| { :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}') AND
settings.var = '#{var}'" } }
scope :without_settings, :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}')",
:conditions => 'settings.id IS NULL'
scope :without_settings_for, lambda { |var| { :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}') AND
settings.var = '#{var}'",
:conditions => 'settings.id IS NULL' } }
end
end
end
end
end
end
What I don't understand is why he uses class_eval on ActiveRecord::Base, wasn't it easier if he just open the ActiveRecord::Base class and define the functions? Specially that there's nothing dynamic in the block (What I mean by dynamic is when you do class_eval or instance_eval on a string containing variables)
something like this:
module ActiveRecord
class Base
def self.has_settings
class_eval do
def settings
RailsSettings::ScopedSettings.for_thing(self)
end
scope :with_settings, :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}')",
:select => "DISTINCT #{self.table_name}.*"
scope :with_settings_for, lambda { |var| { :joins => "JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}') AND
settings.var = '#{var}'" } }
scope :without_settings, :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}')",
:conditions => 'settings.id IS NULL'
scope :without_settings_for, lambda { |var| { :joins => "LEFT JOIN settings ON (settings.thing_id = #{self.table_name}.#{self.primary_key} AND
settings.thing_type = '#{self.base_class.name}') AND
settings.var = '#{var}'",
:conditions => 'settings.id IS NULL' } }
end
end
end
end
I understand the second class_eval (before the def settings) is to define functions on the fly on every class that 'has_settings' right ? Same question here, I think he could use "def self.settings" instead of "class_eval.... def settings", no ?

Hi, I am learning the Opengl graphic programming at Eclipse. Can someone tell me the difference between GLUT application and SDL application, so that I can dig into either one of them? Tks.
I need to develop a geometry library in python, describing points, lines and planes in 3d space, and various geometry operations. Related to my previous question.
The main issue in the design is if these entities should have identity or not. I was wondering if there's a similar library out there (developed in another language) to take inspiration from, what is the chosen design, and in particular the reason for one choice vs. the other.
hello I'm new to PHP programming and I migrated from ASP .net to PHP..

I have just recently graduated from High School and I am looking for something productive to do over the summer. I was thinking of possibly learning a new language that can give me an edge in school or a good project to pursue that will look good on my resume for future jobs. Also how would I go about getting a job right out of high school or interning for a company for the summer?
Thanks in advance.

I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.
After several Google searches, it appears that the way to create PDFs in Rails from HTML and CSS (versus a new markup language) is to use Prince.
With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the whats and hows.
Hello,
I know it's not really a programming question but I don't know where to ask it.
Should i use a captcha in my sign up form ?
Facebook, twitter, foursquare, gowalla etc... don't use one (or not a visible one). Is there an invisible catpcha on theses sites ?
Thank you
Hi, Im a newbie in XML and i have some questions
Can XML be used in stead of normal database (store data in a tuple and column) in website?
XML is built to share information easier (from my understanding) such as can share cross platform and in different language used so Is it secure to store secure data in XML?
thank you so much
This question was inspired by what-features-would-you-like-to-see-added-to-c. anBasically, C++ is a great general-purpose language. But perhaps too general and feature-rich... multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could just go on. Is there any one feature / aspect of C++ that you would like taken away, to make our lives easier as C++ developers?
One feature per answer, please.
Basically, I've got a homework task of programming a text based battle simulator in Python. Obviously I've gone with pokémon...
I would like the enemy to be randomly selected, however I don't know how to randomly select from a list...
foo = ['a', 'b', 'c', 'd', 'e']
from random import choice
print choice(foo)
This is what I've been told to try but I've got no modules or anything imported...
How can I make this work,
appreciated.
