3,601,947 | 3,601,948 | Where is the default parameter in Python function | <p>I think many people have seen the python's function which receives default parameters. For example:</p>
<pre><code>def foo(a=[]):
a.append(3)
return a
</code></pre>
<p>If we call this function using foo(), the output will append integer '3' each time after the call.</p>
<p>When this function is defined, a function object named 'foo' is defined in the current environment, and also the default parameter values are evaluated at this time. Every time when the function is called without a parameter, the evaluated parameter value will be changed according to the code.</p>
<p>My question is, <strong>where is this evaluated parameter exist?</strong>
<strong>Is it in the function object or it is in the method object when calling the function?</strong>
Since everything in python is a object, there must be some place to hold the name->value binding of 'a'-->evaluated parameter. Am I over-thinking this problem?</p>

How the adb works in detail if i start the debug process? Can anybody help me with this problem? I spent 16 hours of finding out what the problem is, but the only things I found out are that the problem has nothing to do with the installation of the eclipse, the adt plugin or the android sdk installation. Something with the connection between the emulator or my real device dont work.
If i create a new project and only change the appname or the text in the standard textview, then the app can be launched on the devices. If i do more changes for example create a new layout or something then the app wont work anymore. I am very frustrating in finding out whats wrong with the adb but till now i dont have luck to solve the problem. I hope someone can help me and others with the same problem. thanks.</p>

1,405,104 | 1,405,105 | Line 6 of this Javascript program is confusing me | <p>In the function <code>takeNormal()</code> below, there is a line that I don't understand at all. It is: </p>

<p>Specifically, in this function reduce, it has all these different arguments (are they arguments?). How are they processed by reduce? Are they handled one after the other? Or, for example, does <code>Math.min</code> do anything to <code>text.length</code>? How do the different parts in reduce interact and what does reduce ultimately do to them?</p>
<pre><code> function splitParagraph(text) {
function indexOrEnd(character) {
var index = text.indexOf(character);

1,149,691 | 1,149,692 | Should I schedule an operation performed in an Android custom Application class onCreate() method? | <p>I have an Android application which depends on the value returned by a webservice. This value changes only once a week. Clients should detect this changed value, but the exact time they detect this change is not really important, 12 to 24 hours later should be no problem.</p>
<p>My current implementation starts an IntentService in the onCreate() method of my custom Application class which retrieves the value from the webservice. I also persist the last retrieved value in the SharedPreferences, so the application does not have to wait until this value is retrieved.</p>
<p>Now my question is if it is necessary to schedule the retrieval of this value after it's first retrieval in the onCreate() method, lets say after 12 hours. I know the onCreate() method is called only once in the lifecycle of an application, but I do not know how likely it is an application will be terminated by the Android system. Is it reasonable to assume that the application will be terminated enough times so that scheduling is not necessary? And in the case I should schedule the operation, what will be the best way to achieve this?</p>

2,123,413 | 2,123,414 | NSLocale is mostly empty - where are the attributes? | <p>I really just want to know whether the user has set the iPhone to 12 hour mode for time display.</p>
<p>The NSLocale class seemed to be describing (in vague unspecific terms without any examples or apparently useful methods) what I was after.</p>
<p>So I have created some NSLocale objects like so:</p>
<p>NSLocale *systemLocaleApparently = [NSLocale systemLocale];
NSLocale *currentLocaleWithLotsOfGoodies = [NSLocale autoupdatingCurrentLocale];</p>
<p>When I inspect these objects using the debugger or NSLog(), the best I can get is something along these lines:</p>
<p>{type = system, identifier = ''} </p>
<p>The current locale has an ID string in it, but nothing else.</p>
<p>From the documentation, I can lookup values from the locale, and one of these is an NSCalendar object. So I get that back and have a look at it, and it tells me it is "gregorian".</p>
<p>All of which is apparently of use to somebody... but what I would really like is a nice big dictionary of attributes showing all of the actual system properties, mainly so that my NSDateFormatters don't keep blowing up when a user chooses 12 hour format even though I have forced the formatters to use en_US_POSIX locale and a fixed setDate format.</p>
<p>(I'm sure NSCalendarDate never used to have these problems...)</p>
<p>Hopefully I am missing something blatantly (and probably embarrassingly) obvious, but perhaps someone kind would share it with me. Please :)</p>

3,622,539 | 3,622,540 | Editing a Photo | From ( X by Y ) to ( A by A ) | <p>When I upload my Facebook photo there are no requirements on the x and y dimensions of the photo. However Facebook finds a way to insert a 50px by 50px photo that is not distorted into the news feed. </p>
<p>The only way you could do this, unless I am mistaken, is by cropping the image so that x and y are equal and then scaling to 50px by 50px.</p>
<p>But I never see any photos with like half a face or off-centered. So how do they determine how to do the cropping. Are they using some sort of face detection algorithm or are users required to to this centering manually?</p>

5,376,719 | 5,376,720 | C++ implicit conversions | <p>Several comments on a recent answer of mine, <a href="http://stackoverflow.com/questions/862858/what-other-useful-casts-can-be-used-in-c/862896#862896">http://stackoverflow.com/questions/862858/what-other-useful-casts-can-be-used-in-c/862896#862896</a>, suggest that my understanding of C++ conversions is faulty. Just to clarify the issue, consider the following code:</p>
<pre><code>#include <string>
struct A {
A( const std::string & s ) {}
};
void func( const A & a ) {
}
int main() {
func( "one" ); // error
func( A("two") ); // ok
func( std::string("three") ); // ok
}
</code></pre>
<p>My assertion was that the the first function call is an error, becauuse there is no conversion from a const char * to an A. There is a conversion from a string to an A, but using this would involve more than one conversion. My understanding is that this is not allowed, and this seems to be confirmed by g++ 4.4.0 & Comeau compilers. With Comeau, I get the following error:</p>
<pre><code>"ComeauTest.c", line 11: error: no suitable constructor exists
to convert from "const char [4]" to "A"
func( "one" ); // error
</code></pre>
<p>If you can point out, where I am wrong, either here or in the original answer, preferably with reference to the C++ Standard, please do so.</p>
<p><strong>And the answer from the C++ standard seems to be:</strong> </p>
<blockquote>
<p>At most one user-defined conversion
(constructor or conversion function)
is implicitly applied to a single value.</p>
</blockquote>
<p><strong>Thanks to Abhay for providing the quote.</strong></p>
