3,745,354 | 3,745,355 | Learning C++ right? | <p>Since I have been mostly using script languages in the past time but now want to go to the "high-performance" level I decided to learn C++ some time ago.</p>
<p>I looked at some "beginner" tutorials and bought an O'reilly C++ pocket reference book (it's really helpful). My problem is that I now know all the basics but I'm not good enought to program a more complicated game, for example, yet.</p>
<ul>
<li>Do I have to get one of those thick C++ books for further learning?</li>
<li>I'm going to use C++ on Windows mainly. What APIs beside Win32 are important for me?</li>
<li>My goal would be to write a small interpreter for a programming language I've though of - I managed that in several scripting languages already, what API/Library knowledge do I need in C++ to write one?</li>
</ul>

I'm to calculate the average of all the elements in the second array and finally have both sets of data stored in respective arrays of primitive data types.</p>
<p>Of course the task is easy so the question isn't directly about it - rather, about the <em>array</em> part. As I don't know how many pairs I'll have to store, I use two ArrayLists to store it. The spec strictly points that in the end, however, both ints and doubles have to be store in primitive arrays - and here comes my question. Is there some faster way to do this than just copying the ArrayList to a primitive type array? I can't use an array from the beginning since I don't know the size or even an upper bound and using toArray() also woulnd't work as I have to have primitive int[] and double[] in the end, not objects of Integer[] and Double[].</p>

So I have created various games before in Java, using buffers and graphics to draw lines and stuff. How do I do that stuff in android? I looked at some online guides, and they all seem to create a class to extend a View object, and the class will overrule the onDraw method, where they can cause the Canvas or something to draw a line.</p>
<p>But what if you want to draw a line based on user input? That method wouldn't work then would it?</p>
<p>For example, what is the simplest code for which I could draw a circle where the user touches the screen?</p>

<pre><code> <Category('Analyze', 'True', 'False', 'False', 'FINAL')>
</code></pre>
<p>Now this is not the same instance. By this I mean, I get all the values from the database and create the dictionary. Then after a while I get an id and retrieve the instance from the database. Now they are not the same objects. I now have to check if it's in the dictionary, but:</p>
<pre><code>instance in disctionary

<p>Will return false. Now I could go the ugly way and iterate over the dictionary checking if all the values match, however does Python have a more clever way to do this? I mean something like the equivalent of Comparable in Java?</p>

4,077,031 | 4,077,032 | Javascript Callback Timing | <p>I feel foolish for asking something so trivial, but I really want the best-practices answer (I'm not looking for a "setTimeout" solution unless nothing else is possible -- though I doubt that is the case).</p>
<p>The quick over-view: I have an array which I want to push to from within a callback. After I've populated the array I then want to use it, outside of the callbacks.</p>
<p>The practical use: I have an array of cities, I want to geocode them with Google's API and populate an array with all of the resulting LatLng's. Later I will create marker objects with them, add them to a clusterer, whatever.</p>
<pre><code>coder = new google.maps.Geocoder();
$places = ['Truro, NS', 'Halifax, NS', 'Sydney, NS', 'Dartmouth, NS'];
all_the_pins = Array();
for(i in $places){
var $place = $places[i];
coder.geocode({address:$place}, function(res, stat){
switch(stat){
case 'OK':
all_the_pins.push(res[0].geometry.location);
break;
}
});
}
console.log(all_the_pins);
</code></pre>
<p>EDIT: to clarify the issue:
The problem isn't a question of scope or whether or not the <code>all_the_pins</code> variable is global or not, if you were to examine <code>all_the_pins</code> within the callback you will see that it is the same variable (which is being pushed to). The problem is that because the pushes happen within the callback they don't happen before the <code>console.log</code> is run below.</p>
