5,460,481 | 5,460,482 | How to set or export display variable through java code? | <p>We are required to add <code>export DISPLAY=:0.0</code> in tomcat's startup file and batch server's startup file. This is to make java see the X11 Display libraries on Unix and run our applet. Without this export in the startup files, the applet throws a Headless Exception.</p>
<p>Though this explicit export makes the java applet run, it disrupts the other applications running on the server. Is there a way where I can make this <code>export DISPLAY=:0.0</code> run from within java code instead of adding it to startup files? And if it is possible, would that be a good approach?</p>
<p>I have already tried setting the system property to <code>-Djava.awt.headless=true</code> , but it didn't work. As the link given above <a href="http://java.sun.com/developer/technicalArticles/J2SE/Desktop/headless/" rel="nofollow">http://java.sun.com/developer/technicalArticles/J2SE/Desktop/headless/</a> also says that setting headless=true would work only for few components like Canvas, Panel but it will not work for the top level components.</p>
<p>So I feel the only option left for me is using <code>export DISPLAY=:0.0</code>. This is making my applet work when set in the startup files but causes problem for other applications running in the server. So if anybody could help me to make <code>export DISPLAY=:0.0</code> work such that it doesn't interfere with other applications in the server. One way I thought was to export the display through code. </p>
<p>Any help would be highly appreciated.</p>

458,123 | 458,124 | BaseAdapter or ArrayAdaptor - Android | <p>I am going to make a grid of images and I am trying to figure out whether to use an array adaptor or a baseadaptor. While the <a href="http://developer.android.com/resources/tutorials/views/hello-gridview.html">GridView example</a>, stores the data in an array, it uses a BaseAdapter rather than a ArrayAdaptor. I am curious why this is. One thing I noticed about an ArrayAdapter, is that its constructor takes a <code>textViewResourceId</code> for some unknown reason - although the documentation say the getView can be used to make it work with other kinds of views as well. So, if I want a fixed grid of images for a menu, which class would you recommend choosing?</p>

5,160,330 | 5,160,331 | Explicit casting to uint when there is no such operator | <p>I have written a simple wrapper around a <code>ulong</code> with a private data member. I want to be able to cast the wrapper to <code>ulong</code> to retrieve the data. I want it to be illegal to cast to <code>uint</code> and lose data, so I did not write an explicit cast to <code>uint</code>. You can imagine my surprise when C# allowed me to cast to <code>uint</code> without complaint and did not throw an exception even though the high bits were lost. </p>
<p>Here is my test code:</p>
<pre><code>class Program {
static void Main(string[] args) {
ULongWrapper a = new ULongWrapper(0xfffffffffUL);
ulong b = (ulong)a;
uint c = (uint)a;
Console.WriteLine("{0:x}", b);
Console.WriteLine("{0:x}", c);
}
}
class ULongWrapper {
private ulong data;
public ULongWrapper(ulong data) {
this.data = data;
}
public static explicit operator ulong(ULongWrapper x) {
return x.data;
}
}
</code></pre>
<p>Which prints:</p>
<pre><code>fffffffff
ffffffff
</code></pre>
<p>This seems like unwanted behavior, since I want casts to <code>uint</code> to fail at compile time! The compiler is using the <code>ulong</code> explicit cast operator and then somehow implicitly casting that result to a <code>uint</code> without bounds checking. Is this a bug in C#, and if not, why?</p>

4,251,516 | 4,251,517 | Efficient data structure for Zobrist keys | <p>Zobrist keys are 64bit hashed values used in board games to univocally represent different positions found during a tree search. They are usually stored in arrays having a size of 1000K entries or more (each entry is about 10 bytes long). The table is usually accessed by <code>hashKey % size</code> as index. What kind of STL container would you use to represent this sort of table? Consider that since the size of the table is limited collisions might happen. With a "plain" array I would have to handle this case, so I thought of an unordered_map, but since the implementation is not specified, I am not sure how efficient it will be while the map is being populated. </p>

2,441,304 | 2,441,305 | Supporting iOS versions prior to 4.0/3.2 and problems with NSClassFromString | <p>I'm currently developing iPhone applications that -- for the time being -- need to be supported on versions prior to 4.x.</p>
<p>When I want to use something 4.x or 3.2 specific, I would use the usual approach of checking if a given class exists, i.e.:</p>
<pre><code>if(NSClassFromString(@"SomeClass")) {
// do stuff here
}
</code></pre>
<p>This mostly works, except when it doesn't.
Let me explain:</p>
<p>Classes like:</p>
<ul>
<li>UIMoviePlayerViewController (only available on 3.2+ according to the documentation)</li>
<li>UIGestureRecognizer subclasses (like UIPanGestureRecognizer; UITapGestureRecognizer, etc.)</li>
</ul>
<p>Actually resolve to valid classes, as if they were already available on private APIs on earlier versions.
Is this the case, or am I missing something?</p>
<p>This is really bad, since the <code>NSClassFromString()</code> approach is actually recommended by Apple.</p>
<p>To be on the safe side, I'm currently checking the OS version instead of doing runtime checking for the classes existence.</p>
<p>Anyone else having this problem?
Thanks.</p>

188,250 | 188,251 | Floating Point Numbers | <p>This seems like a real simple question but I just to want clear my doubt. I am looking at code which some other developer wrote. There are some calculations involving floating-point numbers.</p>
<p>Example: <code>Float fNotAvlbl = new Float(-99);</code> Why is he creating a new object? What would happen if we do <code>Float fNotAvlbl = -99;</code>(-99 is used as flag here to indicate Not Applicable) Later down the code, we define: </p>
<pre><code>fltValue1 = 0.00f;
fltValue2 = 0.00f;
</code></pre>
<p>and populate these two values with a method call which returns float. After that we again convert these two values into Float Objects with:</p>
<pre><code>fltVal1 = new Float(fltValue1);
fltVal2 = new Float(fltValue2);
</code></pre>
<p>and than do a comparison <code>if(fltVal1.compareTo(fNotAvailable) == 0) do something.</code><br>
Is it all because compareTo expects Wrapper Class Objects?</p>
<p>I apologize if this is a real basic question.</p>

<p>Is there an inherent difference in using <code>.prop()</code> over <code>.data()</code> ? </p>
<p>I see in the documentation that not removing a property can result in memory leaks in versions of IE prior to IE9. But are there any other performance issues or other issues with using the new <code>prop()</code> method?</p>
<p>Syntax from the site:</p>
<pre><code>var $para = $("p");
$para.prop("luggageCode", 1234);

1,338,871 | 1,338,872 | Noob question about a statement in a Java program | <p>I am beginner to java and was trying out this code puzzle from the book head first java which I solved as follows and got the output correct :D</p>

d.playTopHat();
}
}
</code></pre>
<p>Output is ::</p>
<p>bang bang ba-bang
ding ding da-ding</p>
<p>Now the problem is that in that code puzzle one code snippet is left that I did not include..it's as follows</p>
<p>d.snare=false;</p>
<p>Even though I did not write it , I got the output like the book. I am wondering why is there need for us to set it's value as false even when we know the code is gonna run without it too !??</p>
<p>I am wondering what the coder had in mind ..I mean what could be the possible future use and motive behind doing this ?</p>
<p>I am sorry if it's a dumb question. I just wanna know why or why not to include that particular statement ? It's not like there's a loop or something that we need to come out of. Why is that statement there ?</p>

5,260,674 | 5,260,675 | Made a website in ASP.NET 4.0, my web host is on ASP.NET 2.0 | <p>I developed a website using Microsoft Visual Web Developer 2010. I'm not a serious programmer, but I can get by if the software is user-friendly enough. Anyway, I have come to learn that the website I developed was on <strong>ASP.NET 4.0</strong> -- I think it might be 4.0.30319, as I look in my computer-->c:/-->windows-->microsoft.net-->framework.</p>
<p>Anyway, the webhosting company I'm with has <strong>ASP.NET 2.0</strong> installed on their servers. Consequently, when I uploaded my site, I get a runtime error, telling me that my web.config is wrong, or whatever. But I'm positive that it's because my website is in 4.0, and their servers are on 2.0.</p>
<p>Well, this is a company website, so it needs to get up ASAP. I know I could switch hosts and all that, but does anybody know of an easier fix? I tried deleting the web.config and the site loaded, but it was all screwed up. The site works fine in my localhost. </p>
<p><strong>So the long and short of it -- is there anything I can do to make my site work on a server that has only the ASP.NET 2.0 framework?</strong></p>

2,388,036 | 2,388,037 | Accesing Non Inherited members, via base class | <p>I have an Abstract class called <code>Function</code> which has 2 inheriting classes (actually 6, but for example 2).</p>
<p>The first inheriting class will be called <code>Push</code>, the other <code>Lift</code>.</p>
<p>The base class will have simple methods and members like <code>Execute(int Distance)</code>, <code>Direction</code> etc..</p>
<p>But the child classes will have individual and unique members, for instance <code>Push</code> will have <code>int friction</code>, and <code>Lift</code> will have <code>int gravity</code> (My one is btw more complicated)</p>
<p>So if I have a <code>List< Function ></code>, how would I edit the <code>gravity</code> member if the object were <code>Lift</code> or the <code>friction</code> if it were <code>Push</code>?</p>
<p><em>Please do not say "Why not make Friction and gravity the same int, and put it in the base class."</em></p>
<p>I was thinking that the base class could have <code>getData()</code> and <code>setData()</code>, which would take an Array and the child classes can use data in the array and handle it differently whilst being able to send different data too.</p>
<p>EDIT: For people stuck with this problem, if possible use a property grid it works much better and is not error prone.</p>
