  - by Edward Tanguay

• How do I define constant values of UIColor?

  - by mobibob

  I want to do something like this, but I cannot get a cooperative syntax. static const UIColor *colorNavbar = [UIColor colorWithRed: 197.0/255.0 green: 169.0/255.0 blue: 140.0/255.0 alpha: 1.0]; I suppose that I could define macros, but they are ugly.

• How to define and use Python generators appropriately

  - by Morlock

  I want to define a generator from a list that will output the elements one at a time, then use this generator object in an appropriate manner. a = ["Hello", "world", "!"] b = (x for x in a) c = next(b, None) while c != None: print c, c = next(b, None) Is there anything wrong or improvable with the while approach here? Is there a way to avoid having to assign 'c' before the loop? Thanks!

For example: the polynomial represented by [-1, 2, -3, 4, -5] would be returned as: "-5x**4 + 4x**3 -3x**2 + 2x**1 - 1x**0" def polyToString(poly): standard_form='' n=len(poly) - 1 while n >=0: if poly[n]>=0: if n==len(poly)-1: standard_form= standard_form + ' '+ str(poly[n]) + 'x**%d'%n else: standard_form= standard_form + ' + '+str(poly[n]) + 'x**%d'%n else: standard_form= standard_form + ' - ' + str(abs(poly[n])) + 'x**' + str(n) n=n-1 return standard_form

• How to define colors in XCodes' Interface Builder?

  Hi, I would like to copy colors between elements in the interface builder or define them using RGB values. I.e. copy the background color of a button to another button without duplicating the button. Or: Enter an exact RGB code using the interface builder.

• Define Rails Model Persistent Attributes in Model File

  - by Kevin Sylvestre

  I recently played with MongoDB in Rails using Mongoid. I like the ability to define attributes for models within the model file (as opposed to in migrations): class Person include Mongoid::Document field :name, :type => String field :birthday, :type => Date end For projects that cannot use a schema-less database, does a similar feature exist? Any gems or plugins that generate schemas from a similar syntax would be greatly appreciated. Thanks.
