• How can I merge properties of two JavaScript objects dynamically?

  - by JC Grubbs

  I need to be able to merge two (very simple) JavaScript objects at runtime. For example I'd like to: var obj1 = { food: 'pizza', car: 'ford' } var obj2 = { animal: 'dog' } obj1.merge(obj2); //obj1 now has three properties: food, car, and animal Does anyone have a script for this or know of a built in way to do this? I do not need recursion, and I do not need to merge functions, just methods on flat objects.

• Why doesn't Apple make private APIs inaccessible?

  - by Howiecamp

  If Apple doesn't want developers using private APIs in the iPhone SDK, why don't they do something like mark the classes and/or methods with whatever the Objective-C equivalent of C#'s "internal" keyword? If the APIs are spread amongst multiple binaries, Apple could refactor them into dedicated private-API-only binaries to make this easier for them.

• What method should be used for searching this mysql dataset?

  - by GeoffreyF67

  I've got a mysql dataset that contains 86 million rows. I need to have a relatively fast search through this data. The data I'll be searching through is all strings. I also need to do partial matches. Now, if I have 'foobar' and search for '%oob%' I know it'll be really slow - it has to look at every row to see if there is a match. What methods can be used to speed queries like this up? G-Man

  - by Sheehan Alam

  I have a very basic data class that is subclassed from NSObject. I declare a few strings, make sure they have properties (nonatomic, copy), and synthesize them. The only method I implemented was dealloc() which releases my strings. Can any memory problems arise from just this? Are there any other methods I need to implement?

• Getting started with nbehave

  - by dotnetdev

  Hi, I am looking at using BDD, however, when evaluating the stories/conditions I write (using nBehave), how do I check if the story passes? Do I write another library with test methods? For example, if I want to test a site for having a link called "About", do I write a method which can check this and then another method in another class library which can call the method to check the link via lambda syntax and add the relevant test and bdd attributes? Thanks

• Is there any way to delete an HttpOnly cookie from C# Selenium tests?

  - by BenA

  I have a set of C# Selenium tests that need to delete a cookie that has the HttpOnly flag set. Unfortunately the DefaultSelenium.GetCookie() and DefaultSelenium.DeleteCookie() commands aren't able to access the cookie, because it has that HttpOnly flag set. I've confirmed this by removing the flag by hand, and checking that subsequent calls to either of those methods are then happily able to manipulate the cookie in question. Is there any other way to do this via the Selenium .NET client driver? All ideas welcome!

• main vs initialize in Ruby

  - by Dave

  Okay, so I've looked through a couple of my ruby books and done some googling to no avail. What is the difference between main and initialize in Ruby? I've seen code that uses class Blahblah def main some logic here end #more methods... end and then calls it using Blahblah.new. Isn't new reserved only for initialize? if not, then what's the difference between the two?

• Processing image data in java me

  - by Trimack

  Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  If you have the binary number 10110 how can I get it to return 11111? e.g a new binary number that sets all bits to 1 after the first 1, there are some likewise examples listed below: 101 should return 111 (3 bit length) 011 should return 11 (2 bit length) 11100 should be return 11111 (5 bit length) 101010101 should return 111111111 (9 bit length) How can this be obtained the easiest way in Java? I could come up with some methods but they are not very "pretty".

• Convert UTF-16 to UTF-8 under Windows and Linux, in C

  - by DooriBar

  I was wondering if there is a recommended 'cross' Windows and Linux method for the purpose of converting strings from UTF-16LE to UTF-8? or one should use different methods for each environment? I've managed to google few references to 'iconv' , but for somreason I can't find samples of basic conversions, such as - converting a wchar_t UTF-16 to UTF-8. Anybody can recommend a method that would be 'cross', and if you know of references or a guide with samples, would very appreciate it. Thanks, Doori Bar

• rails declarative authorization, permit all actions for controller?

  - by SooDesuNe

  using the delcarative_authorization gem for rails, is there a shortcut to allow a role access to all controller actions? privileges do # default privilege hierarchies to facilitate RESTful Rails apps privilege :manage, :includes => [:create, :read, :update, :delete] end isn't sufficient, because I have more controlling methods than just CRUD in my controllers. Something like: role :foo do has_permission_on :bar, :to =>[:all] end would be perfect, but I'm not finding it in the docs.
