What makes the availability of both primitive and object-wrapped values in JavaScript useful?
- by Delan Azabani
I wrote a blog post a while ago detailing how the availability of both primitive and object-wrapped value types in JavaScript (for things such as Number, String and Boolean) causes trouble, including but not limited to type-casting to a boolean (e.g. object-wrapped NaN, "" and false actually type-cast to true). My question is, with all this confusion and problems, is there any benefit to JavaScript having both types of values for the built-in classes?Read the article

About to migrate :string but I'm thinking :text might be better. Performance/Purpose?
- by Sam
class CreateScrapes < ActiveRecord::Migration def self.up create_table :scrapes do |t| t.text :saved_characters t.text :sanitized_characters t.string :href t.timestamps end end def self.down drop_table :scrapes end end I'm about to rake db:migrate and I'm think about the attribute type if I should be using text or string. Since saved_characters and sanitized_characters will be arrays with thousands of unicode values, its basically comma delimited data, I'm not sure if `:text' is really the right way to go here. What would you do?Read the article

In Android OS or Java, what's the difference between a character sequence and a string????
- by K-RAN
For the API (Android SDK API version 8) functions whose definitions list character sequence parameters, I can feed the function String instead. Best part is that they work the same way, no hassle, no warnings. Is there a difference between the two types? And more importantly, is there an inherent danger if I send the function a String instead of a character sequence??? Thanks for any clarifications!!! :DRead the article

- by Chas. Owens
If a string in Perl 5 passes looks_like_number, it might as well be a number. For instance, my $s = "10" + 5; results in $s being assigned 15. Are there any cases where a string does not behave like it's numeric equivalent would have?Read the article

Detect when a new property is added to a Javascript object?
- by UICodes
A simple example using a built-in javascript object: navigator.my_new_property = "some value"; //can we detect that this new property was added? I don't want to constantly poll the object to check for new properties. Is there some type of higher level setter for objects instead of explicitly stating the property to monitor? Again, I don't want to detect if the property value changed, but rather when a new property is added. Ideas? thanksRead the article
