4,088,941 | 4,088,942 | Can i code C++ for non-os x based frameworks and such on Xcode? | <p>I have just begun learning C++ through a flemmish government funded course. I was given 'thinking in c++' by Bruce Eckel as my educative material.</p>
<p>Besides learning c++ i'm also picking up objective-c on my own as I go, my long-tearm goal is to be a independent osx/ios dev, but i have to learn an succeed in c++ for the funding to continue. Betting on two horses and such.. you're getting the picture, i'm sure. </p>
<p>So now it begins. I have to choose an IDE. Xcode seems only to serve the os x oriented C++ development as far as I understand... Am i right? </p>
<p>I would consider other IDE's like eclipse or even go linux and what not, but in the end, long term, I'm going to be coding in Xcode because of my independent ambitions... So it would be really convenient if I could get started with Xcode right away, nice and comfy, so i don't have to divide my 'learning curve' an lose valuable time</p>
<p>So the question nice and short; is it possible to code C++ for non-osx based sources and frameworks and what not. More importantly, can i learn everything in the book by Eckel if i stick to Xcode?</p>
<p>I'm a new kid on the block. Forgive stupid questions and wrong usage of dev lingo. </p>
<p>much obliged.</p>

166,864 | 166,865 | Using non-hashable Python objects as keys in dictionaries | <p>Python doesn't allow non-hashable objects to be used as keys in other dictionaries. As pointed out by Andrey Vlasovskikh, there is a nice workaround for the special case of using non-nested dictionaries as keys:</p>
<pre><code>frozenset(a.items())#Can be put in the dictionary instead
</code></pre>
<p>Is there a method of using arbitrary objects as keys in dictionaries?</p>
<p><strong>Example</strong>:</p>
<p>How would this be used as a key?</p>
<pre><code>{"a":1, "b":{"c":10}}
</code></pre>
<p><strong>It is extremely rare that you will actually have to use something like this in your code. If you think this is the case, consider changing your data model first.</strong></p>
<p><strong>Exact use case</strong></p>
<p>The use case is caching calls to an arbitrary keyword only function. Each key in the dictionary is a string (the name of the argument) and the objects can be quite complicated, consisting of layered dictionaries, lists, tuples, ect.</p>
<p><strong>Related problems</strong></p>
<p>This sub-problem has been split off from <a href="http://stackoverflow.com/questions/1600591/using-a-python-dictionary-as-a-key">the problem here</a>. Solutions here deal with the case where the dictionaries is not layered.</p>

3,427,655 | 3,427,656 | Difference between creating a global variable, vs one in a constructor function in JavaScript | <p>If I declare a global variable x as:</p>
<pre><code>var x = "I am window.x";
</code></pre>
<p>x will be a public property of the window object.
If I call a global function (without using "call", "apply" or attaching it to another object first), the window object will be passed in as the context (the “this” keyword).
It is like it is siting the x property on the current context, which happens to be the window.</p>
<p>If, however, I declare a variable in the same way inside a function, then use that function as a constructor, the property x will not be a public property of the object I just constructed (the current context). I am happy (I know I can do this.x = …), but it just seems like a bit of a contradiction.</p>

So in this case, the enum definition must be doing something to prevent that.

And this code is used in production, almost everywhere?</p>

struct MyInterface {
MyInterface() {
InterfaceList().push_back(this);

class MyImplementation: public MyInterface {
public:
MyImplementation() {
}
// ...
};
MyImplementation impl;

<p>This doesn't seem to work. For reasons I don't understand, the constructor of MyInterface never gets called - I would have thought that the instance of the derived class would call it at startup. I know it's possible to do something along these lines since I've seen other libraries doing it - but haven't managed to figure out what it is that I'm doing wrong.</p>
<p>Thanks :)</p>
<p>Edit: Sorry, missed a pair of braces and a reference. InterfaceList() is a function that returns a reference to a vector.</p>
<p>Edit part 2: Have now got it working in a reduced example, but can't get it to work in the files for the derived implementations - but that technique is working in another project. There must be something slightly different in those files which is causing it to fail - but it appears the problem isn't in the code I posted. Don't really want to post big chunks of my employer's projects though so I guess I'll have to keep fiddling myself. Thanks for the suggestions so far though :)</p>
