<p><a href="http://stackoverflow.com/questions/5032131/is-there-a-java-or-ruby-library-for-generating-mobi-ebook-documents">Is there a Java or Ruby library for generating MOBI ebook documents?</a></p>
<p>The answer basically gives a link to amazon and discusses using command line tools which is not really satisfactory for a web app. I want a regular jar file w/ an api that i can invoke without any nasty process invocation.</p>
<p>Does anyone know of a FOSS library that provides this functionality ? I would rather simething like ITEXT that allows me to build the document and then writes the mobi file rather than something that converts an already ready PDF into the MOBI.</p>

4,424,783 | 4,424,784 | iPhone:Tabbar item actions are not happening | <p>I created a window application, which has a tabbar controller with four tabbar items. Each tabbar items are linked with a tableview. I have also set Navigation bar for each tabbar items.
I have appdelegate file, which calls the first tableview controller of which is set for first tabbar item.
I am trying to retrieve and do an action whenever a tabbar item is clicked. For that, i tried to add
"- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item" and
"- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UITableViewController *)viewController"</p>
<p>in my first tableview controller, but it is not at all responding whenever i click any tabbar items.
My question is, if i create a window based application and added tabbar controller, tableview and navigation bar in .XIB file, is it not possible to access and do an action programatically whenever a tabbar item is clicked? (or) Am i doing anything wrong? </p>
<p>Please help me to resolve this and share your ideas.</p>

<pre><code>foo = {}
foo_foo = {}
bar = None
def changes_foo():
...do some stuff to foo...
class EditThread(threading.Thread):
def __init__(self):
setup()

del foo[key]
bar = [key, value]
foo_foo[key] = value
def print_the_bar():
print bar

5,225,407 | 5,225,408 | When to use on("selector") and when on("selector", "selector") | <p>Using jQuery <code>on()</code> version 1.7. I bind my events usually like this:</p>
<pre><code>$(".foo").on("click", function() {
console.log("foo clicked");
})
</code></pre>
<p>Now after seeing someone elses code, I seen you also can bind like this, specifying a secondary parameter for a specific element (Not sure why it was written like this):</p>
<pre><code>$(document).on("click", ".bar", function() {
console.log("bar clicked");
})
</code></pre>
<p>As seen in this <a href="http://jsfiddle.net/JWUyn/1/" rel="nofollow"><strong>fiddle</strong></a>, they both do the same thing.</p>
<p>I always bind directly to the element as in the first code sample and never have any issues.</p>
<p>When would I need to use the other way of binding and what is the benefit of one over the other?</p>

4,336,630 | 4,336,631 | Instantiating a nib object to present in a view | <p>I have a LegendViewController that shows a legend. Originally, I just plopped an UIImageView in there. However now, we need a few legends and I want to reuse the LegendViewController. So I created a new initializer:</p>
<pre><code>- (id)initWithView:(UIView *)view withNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
[self initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
[self.view addSubview:view];
}
return self;
}
</code></pre>
<p>So now this works assuming I pass in a UIView object. For one of my legends, I was wondering if I could load a .xib into my view controller without an image or a UIView object. I have a very simple legend where I just want some color coded squares (UIViews with colors), and some text (UILabels). I can create this in a standalone .xib file, but I wasn't sure how I could load it into my LegendViewController. I've got so far as:</p>
<pre><code>UINib *nib = [UINib nibWithNibName:@"HealthLegend" bundle:nil];
</code></pre>
<p>where HealthLegend is my standalone .xib file with my data. Or can this not be done and I need to either create an image in some drawing program, or draw the code manually in drawRect? Thanks.</p>

1 first line/row is a tool/status bar which I don't know how to access

2. next line is my app name like "Hello World".

<p>I have something like this:</p>

// }
// It will print the name and dob of all the students inserted because I've created

<p>If a variable is created in one case it's values can't be used in another case?

Now I want to release a very small bugfix update, but in the time between my last release and now, I've upgraded Xcode to 3.2.3 and upgraded my test iPhone to 4.0.</p>
<p>Since these are very simple changes, I want my iOS 3.1.2 users to be able to get these fixes but it looks like Xcode wants me to build for iOS 3.2. That doesn't really go back far enough for me.</p>
<p>I've done some research (mostly around SO) and learned that it's possible to use SDK 3.2 and simply set the Deployment Target to 3.1.2. But if I do that, how can I do a basic sanity check of my app's compatibility with that OS, given that I have a brand new development environment and SDK? My physical hardware is now OS 4, and the iPhone Simulator that ships with Xcode doesn't seem to simulate OS 3.1.2.</p>
<p>Is it possible to get an older version of the SDK to test my code? Do I have any other options?</p>

3,722,099 | 3,722,100 | Modern C++ Game Programming Examples | <p>To what extent are modern C++ features like:</p>
<ol>
<li>polymorphism, </li>
<li>STL, </li>
<li>exception safety/handling, </li>
<li>templates with policy-based class design, </li>
<li>smart pointers</li>
<li>new/delete, placement new/delete</li>
</ol>
<p>used in game studios? I would be interested to know the names of libraries and the C++ features they use. For example, Orge3D uses all modern C++ features including exceptions and smart pointers. In other words, if I would be looking for an example for a game library using modern C++, I would go to Orge3D. But I don't know if these features deter game studios from using Orge3D. </p>
<p>Further I don't know if there are other examples. For example, I used Box2D some time before briefly, but it uses only placement new, and class keyword as the C++ features. Even encapsulation is broken in these classes as all members are public. </p>
<p>Ideally, if C++ features would be the best match for all situations, these would be used most often. But it seems not. What are the impedances? The obvious one is having to read stacks of books, but that's half a reason only. This question is a follow up on "<a href="http://stackoverflow.com/questions/829656/c-for-game-programming-love-or-distrust">C++ for Game Programming - Love or Distrust?</a>" (From the responses there I got an impression that many C++ features are still not used in games; which is not necessarily the way it <em>should</em> be).</p>

4,467,276 | 4,467,277 | Is it possible to make the execution of a program skip fprintf-statements/How to create my own fprintf-function? | <p>In my C++-code there are several fprintf-statements, which I have used for debugging. Since I might need them again, I would prefer not to comment them out for the moment.
However, I need the execution of the program to be fast, so I would like to avoid them being printed out, as they are for the moment (I redirected stderr to a file).</p>
<p>Preferably this would be determined by the user passing an argument to the program, which I would extract like this:</p>
<pre><code>main (int argc, char *argv[])
{
int isPrint=0;
if (argc > 1 ) {
isPrint = atoi ( argv[2]);
}
}
</code></pre>
<p>I thought of renaming fprintf to another name, and then from that function do a fprintf-call using the same parameters, based on the value of <strong>isPrint</strong>; however, then I realized that fprintf can have so many different kind of arguments and a various number of arguments; and that I don't know any generic way of declaring my own function with those requirements.</p>
<p>So I wonder how to create a function,which works exactly like fprintf, but which takes the extra parameter <strong>isPrint</strong>; or how to solve the above problem in another way.</p>
<p>Complementary information after first post:
One solution would be to add this before each fprintf-statement:</p>
<pre><code>if (isPrint == true )
