<pre><code> // Setup an intent filter for all MIME based dispatches

try {
ndef.addDataType("*/*");
} catch (MalformedMimeTypeException e) {

ndef,
};
// Setup a tech list for all NfcF tags

</code></pre>
<p><strong>Problem</strong>: I have to put full path to the stylesheet file. So instead of /template/foo.css I have to put: <a href="http://hostname/directory/template/foo.css" rel="nofollow">http://hostname/directory/template/foo.css</a>. I can't set it statically beacause script can be placed in different servers and different locations. So it can be: <a href="http://foo.com/bar/foo.css" rel="nofollow">http://foo.com/bar/foo.css</a> or <a href="http://foo.com/foo.css" rel="nofollow">http://foo.com/foo.css</a>. </p>

2,525,519 | 2,525,520 | how to prevent growing activity stack in android | <p>I read somewhere that each time you call startActivity() to transition to a new screen, you are creating a new instance of that activity. This immediately raised a red flag to me.</p>
<p>In search of a way to prevent this issue, I read about using FLAG_ACTIVITY_REORDER_TO_FRONT. However I'm a little alarmed that this method is not used in any of the tutorials I've seen for opening a new screen in your app. So I think I might be missing something. I mean wouldn't you always want to make sure you're not creating a duplicate Activity? isn't this kind of a big deal and shouldn't tutorials address it? </p>
<p>I just want to make sure that I am understanding, and dealing with, this issue correctly, and using the commonly practiced way to transition between screens.</p>
<p>I understand in some cases you open a screen, do something, then close it using finish() and go back. But if an app has a complex 4 level hierarchy , and the user needs to be able to jump around between the screens?</p>

<p>And I want to just get the id and name using the reader, discarding and ignoring the rest. I tried using fieldnames but it still reads it in and sets it as "None". I noticed that the csv.DictWriter has an 'ignore' function but it seems the DictReader does not. Was hoping there was a more elegant way to do this versus just reading and then writing only the columns I want to another CSV and then reading that CSV using DictReader to do further processing.</p>

2,150,041 | 2,150,042 | python unpack little endian | <p><P>I'm trying to use Python read a binary file. The file is in LSB mode. I import the struct module and use unpack like this:</p>

print contents

<p><p>The data in the file is 0XC0000500 in LSB mode, and the actual value is 0X000500C0. So you can see the LSB mode's smallest size is per byte.
<p>However, I use a Mac machine, perhaps because of the version of my gcc or machine (I am not for sure. I just read the <a href="http://docs.python.org/library/struct.html" rel="nofollow">http://docs.python.org/library/struct.html</a> about the sizeof and sys.bitorder), the result from the above code is X0500C000, so the size of the LSB mode is 2Bytes.

<p>I will keep digging no matter this question is answered or not, and I will update if I ever get something.

174,793 | 174,794 | class properties that can be assigned only when creating object? | <p>It's possible in C# to write things such way:</p>
<pre><code>Instrument instr = new Instrument { ClassCode = "Hello", Ticker = "World" };
</code></pre>
<p>However to do that you have to add <code>set;</code> in the corresponding class:</p>
<pre><code>class Instrument
{
public string ClassCode { get; set; }
public string Ticker { get; set; }
}
</code></pre>
<p>This means that later someone can accidentally change value:</p>
<pre><code>instr.ClassCode.set = "Destroy"
</code></pre>
<p>And I don't want to allow that. I.e., from one hand I want a readonly property, from another hand i want to create objects like that:</p>
<pre><code>Instrument instr = new Instrument { ClassCode = "Hello", Ticker = "World" };
</code></pre>
<p>I'm not sure if this is possible. Probably I should use fields or something else instead of properties. I only want to have the syntax of the last sentence but keep things readonly at the same time.</p>
<p><strong>upd:</strong> In short no, readonly properties are not allowed in any way. Regular constructor and "get" should be used in this case.</p>

4,843,101 | 4,843,102 | Transfering data from a sensor to the iphone | <p>I have an external device (some kind of sensor) that can do a measurment. This sensor can be connected to a PC via Bluetooth or USB cable, and it also comes with its own software.
I want to develop an app for iphone that will analyze the data that this sensor is measuring (for example creating a graph, calculating some equations etc.).
How can i make my iphone to "recognize" this sensor, so the app will get the data that has benn measured from the sensor?
is there any manual which explain how to code this? our preffered way of transfering the data is via Bluetooth, so there will be no need of using cables.</p>
