Dismissing popover, then popToRootViewController, EXC_BAD_ACCESS
|
<p>I am getting a crash when I <code>popToRootViewController</code>, this is the way I have it set up.</p>
<p>I have: </p>
<pre><code>@property (nonatomic, retain) UIPopoverController *popover;
</code></pre>
<p>in dealloc:</p>
<pre><code>[popover release];
</code></pre>
<p>when a button is pressed</p>
<pre><code>if (self.popover == nil) {
DetailViewController *detailView = [[[DetailViewController alloc] init] autorelease];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(GoToTest:) name:TestDetailPressed object:detailView];
self.popover = [[[UIPopoverController alloc] initWithContentViewController:detailView] autorelease];
self.popover.delegate = self;
[self.popover presentPopoverFromRect:frame inView:self.scrollView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
</code></pre>
<p>My <code>DetailViewController</code> is essentially just a <code>UITableView</code>. When a row is selected, I post a notification back to this current class for GoToTest:</p>
<pre><code>- (void)GoToTest:(NSNotification *)notification {
if ([self.popover isPopoverVisible]) {
[self.popover dismisspopoverAnimated:YES];
[self handleDismissedPopover:self.popover];
}
[self.navigationController popToRootViewControllerAnimated:NO];

self.popover.delegate = nil;
[[NSNotificationCenter defaultCenter] removeObserver:self name:TestDetailPressed object:nil];
}
- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
[self handleDismissedPopover:popoverController;
}
</code></pre>
<p>When I run it in Instruments, I get the zombie message for</p>
<pre><code> -[UIPopoverController _popoverDismissAnimationCompleted]
</code></pre>
<p>and the <code>UIViewController</code> has a refCt of -1 at that point.</p>

C# Variable Name To String
|
<p>I have variable</p>
<pre><code>public string MyVariable;
</code></pre>
<p>I need use name of variable as string. Example:</p>
<pre><code>var a = MyVariable.NameVariable();
// a = "MyVariable"
</code></pre>
<p>How i may to do this?</p>
<p>I would like to create your miniORM (NHibernate is too heavy and requires a separate library). At the moment the problem is that I have to point out a bunch of constants. For example:</p>
<pre><code>public const string FieldIdRules = "idRules"
</code></pre>
<p>And then to make transactions in relation samonapisannom profiler.
I saw that Hibernate does not need to specify the text value (for the ratio of fields). I want to implement the same.</p>
<p>Sorry my bad english</p>

JQuery textarea value is empty
|
<p>This type of question tends to immediately get a negative vote. If you have the answer, please help! Thanks.</p>
<p>I have a script that adds a textarea to the dom. When I enter data and later try to retrieve it the value returns empty.</p>
<p>This successfully sets the value of the textarea:</p>
<pre><code>$("textarea").each(function(){
$(this).val("ASDFASDF");
});
</code></pre>
<p>This successfully sets the css background property of the textarea:</p>
<pre><code>$("textarea").each(function(){
$(this).css({"border":"2px solid red"});
});
</code></pre>
<p>But this does not return the value:</p>
<pre><code>$("textarea").each(function(){
alert($(this).val());
});
</code></pre>
<p>I've tried .text(), .html(), .value - they all return nothing! It doesn't alert "undefined" or null but simply an empty value.</p>
<p>I can't figure out why.</p>
<p>Thanks in advance for the suggestions. </p>
<p><strong>MORE INFO</strong></p>
<p>HTML is:</p>

What is the right place to store persistent app data before exiting?
|
<p>I have a single <code>Activity</code> application with a data container that is populated at the launch of the application from a JSON formatted private text file. When exiting the application, whether it's a graceful exit or forced one, the the data must be written back to the text file.</p>
<p>Android documentation <a href="http://developer.android.com/reference/android/app/Activity.html#onDestroy%28%29" rel="nofollow">states</a> that application data shouldn't be saved in the onDestroy method.</p>
<p>I have now overwritten the following methods to make sure the data is stored at exit:</p>
<pre><code>protected void onStop() {
persistenceManager.storeIfChanged();
super.onStop();
}
protected void onPause() {
persistenceManager.storeIfChanged();
super.onPause();
}
</code></pre>
<p>The <code>storeIfChanged</code> methods writes the application data to the text file if it has changed since last save. <strong>My question is</strong>, does this guarantee the application data is saved no matter how the application is terminated (unless it's force majeure). <strong>Secondly</strong>, is it superfluous to do the saving in both onStop and onPause?</p>

How to get some elements from html source and convert them to readable text?

ASP.NET chatting design and speed issues
|
<p>Ok. I am making a random chatting website here, and the website needs to know each user's new visit datetime and a randomID in order to retrieve the messages he/she made in a chatting room. When a user comes in to my website, he/she gets a unique random ID and start to talk to another person. Every comments they make gets saved in a database along with a randomly assigned chatroomID. Then, the database loads the messages in the chatroom (every 1 second) by identifying the users' new visit dates to the chatroomID and retrieving all the users' messages associated with the chatroomID in chronological order (from the new visit date). Do you think that this is a well-designed way to create a random chatting website and if not is there a better design alternative? :D If I reload the messages from the database every 1 second, won't there be speed or traffic issues? If I am not clear on my explanation, plz leave msg and ask me for the details.</p>

Call by reference-stream and char in c++

<p>My latest homework assignment is to write a program that reads a textfile and outputs the number of lines, words and characters.</p>

file_put_contents() not over writing, just appending
|
<p>I have a simple <code>file.txt</code> which needs to be over written every time I run a certain php code.</p>
<pre><code>$msg ="string";
$file = 'file.txt';
$opn = file_get_contents($file);
$opn .= $msg;
file_put_contents($file, $opn);
</code></pre>
<p>The code works perfectly, It added the string I want it to add, but It is appending it to the former. I want it to erase it blank and then write.</p>
<p>I've read the manual <a href="http://php.net/manual/en/function.file-put-contents.php" rel="nofollow">http://php.net/manual/en/function.file-put-contents.php</a>
I am not using the <code>FILE_APPEND</code> argument either.</p>
<p>It's a simple thing that I'm not seeing. Help me out.</p>
<p><strong>EDIT:</strong></p>
<p>Here is the whole code. I'm getting some data from a site. The data is in this format <code>12.222 AAA</code> and I am trying to save that to a text file to easily access later.
But for some reason something does not work. The scraper works perfectly, and the <code>file_put_contents()</code> woks perfectly if I set the <code>$item="string";</code> but it does not work when when <code>$item</code> is set to equal the code below. If I echo $item I get what I want.</p>
<pre><code><?php
include('simple_html_dom.php');
$html = file_get_html('http://site.com/boom');
// find the thing in the span
foreach($html->find('div') as $article) {
$item = $article->find('span', 0)->plaintext;
echo $item;
$file = 'file.txt';
$fh = fopen( 'file.txt', 'w' );
fclose($fh);
$opn = file_get_contents($file);
$opn .= $item;
file_put_contents($file, $opn);

PHP Array count and get element values
|
<p>I'm pretty new to PHP and programming so I'm having troubles with this thing.</p>
<p>The purpose of the whole situation is to read a column from tab delimited file (already did that), get all different items in it, count them individually and put them in table with <br><br>Column1[item value - label], Column2[count].</p>
<p>I have the whole column in 1 dimension array. Now, I want to list all the items there and their counts beside. The problem is, I could have more than 10 different items, even more, so I can't do it manually (name 10 variables and count each) like this:</p>
<pre><code>$arr = array("complete","fail","complete","exit","fail","fail","complete");
function isComplete($value){
return ($value == "complete") ? true : false;
}
$complete = array_filter($array, 'isComplete');
<tr>
<td>Complete</td>
<td><?php echo count($complete)?></td>
</tr>
-- > Complete = 3
</code></pre>
<p>I want to avoid manually creating every function for each value because values can differ from file to file.</p>
<p>The number of items in $array can go up to 20+k so I need all automated. Can someone help me with this?</p>

Get the list of a class's variables & methods in Python

<p>If I have the following class, what's the best way of getting the exact list of variables and methods, <em>excluding</em> those from the superclass?</p>
<pre><code>class Foo(Bar):
var1 = 3.14159265
var2 = Baz()
@property
def var3(self):
return 42
def meth1(self, var):
return var
</code></pre>
<p>I want the tuple <code>('var1','var2','var3','meth1')</code> with minimum overhead. This is being run in a Django environment, which seems to be putting some of it's class instance variables in the read-only <code>__dict__</code> variable; a feat which I can't find a way to replicate.</p>
<p>Here's what I'm seeing while playing with it, any suggestions beyond trimming out the <code>__*</code> from the dir() or manually listing them?</p>

>>> a
<__main__.Foo instance at 0x7f48c1e835f0>
>>> dict(a)

Check if a file is writable before writing to it
|
<p>I'm trying to create a script which will check if a file is writable before writing to it,</p>
<p>Making sure the script doesn't exit prematurely.</p>
<p>I've gotten this far</p>
<pre><code>$meta =stream_get_meta_data($file);
while(!is_writable($meta['uri'])){
sleep(rand(0,3));
$meta=stream_get_meta_data($file);
echo("sleeping\n");
}
$csv = fopen($file, 'a+')or die("can't open file");
</code></pre>
<p>When I test the script with $file open, it blocks on the sleeping part even after $file is closed.</p>
<p>I'm fairly new to PHP, so there might be a processing paradigm that i'm not aware of.</p>
<p>Any help would be very welcome.</p>
<p>EDIT : The reason I entered this into a while loop is to continually check if the file is open or not. Hence it should only exit the while loop once the file is finally writable.</p>
<p>The sleep is simply to replicate a person trying to open the file.</p>

details of finding 2nd smallest element in unsorted array
|
<p>Let me make things clear:
I want to know more about the implementation of the "best" ALGORITHM how to find 2nd smallest element in array, which is described here:</p>
<h2><a href="http://stackoverflow.com/questions/3715935/algorithm-find-index-of-2nd-smallest-element-from-an-unknown-array">Algorithm: Find index of 2nd smallest element from an unknown array</a></h2>
<p>First, I am completely clear about the ALGORITHM how to find 2nd smallest element in array.
The best solution is O(n+lg(n)-2) which can be achieved by first obtaining the smallest element S and then searching the smallest element of S's competitors. Read here:
<a href="http://stackoverflow.com/questions/3715935/algorithm-find-index-of-2nd-smallest-element-from-an-unknown-array">Algorithm: Find index of 2nd smallest element from an unknown array</a></p>
<p>What I cannot understand is how to implement it. </p>
<p>Especially, after finding the smallest element, how to track back those competitors of the smallest element such that I can find 2nd smallest element in those competitors?</p>
<hr>
<h2>NO NEED TO SORT. Quicksort is O(nlg(n)) which is worse than O(n+lg(n)-2).</h2>
<p>There have been too many people talking about the best solution while nobody actually gave an implementation. Besides, I found the best solution is just theoretical best. It is very hard to implement it following that "best" solution.</p>

How to convert a decimal into time, eg. HH:MM:SS
|
<p>I am trying to take a decimal and convert it so that I can echo it as hours, minutes, and seconds.</p>
<p>I have the hours and minutes, but am breaking my brain trying to find the seconds. Been googling for awhile with no luck. I'm sure it is quite simple, but nothing I have tried has worked. Any advice is appreciated!</p>
<p>Here is what I have:</p>
<pre><code>function convertTime($dec)
{
$hour = floor($dec);
$min = round(60*($dec - $hour));
}
</code></pre>
<p>Like I said, I get the hour and minute without issue. Just struggling to get seconds for some reason.</p>
<p>Thanks!</p>

Add a timeout when creating a new Socket
|
<p>I have a local network with DHCP and a few PCs. One of these should be my Server and get automatically connected to all others (clients). My idea was this:
First, I create a server on every client (CServer) that is listening for a client programm from the server (SClient). When the SClient connects to a CServer, the SClient sends the CServer his IP, so he knows there will be the server on this IP. Then after trying all IPs in his IP range (e.g. 192.168.1.xxx), he starts the real server and all the clients connect to the known server IP.
But when I try the following, the SClient just freezes at the first IP, when trying to connect to 192.168.1.0. How can i define a timeout or something similar that lets the SClient drop the unsuccessful connection and going on with 192.168.1.1?</p>
<pre><code>import java.lang.*;
import java.io.*;
import java.net.*;
class SClient {
public SClient() {
for(int i = 120; i < 125; i++){
try{
InetAddress addr = InetAddress.getLocalHost();
String addrs = addr+"";
String ip = addrs.substring(addrs.indexOf("/")+1);
Socket s1 = new Socket("192.168.1." + i, 1254);
OutputStream s1out = s1.getOutputStream();
DataOutputStream dos = new DataOutputStream (s1out);
dos.writeUTF(ip);
dos.close();
s1out.close();
s1.close();
}catch(IOException e){}
}
}
}
</code></pre>
<p>and</p>
<pre><code>import java.lang.*;
import java.io.*;
import java.net.*;
class CServer {
public CServer() throws IOException{
ServerSocket s = new ServerSocket(1254);
while(true){
Socket s1=s.accept();
InputStream s1In = s1.getInputStream();
DataInputStream dis = new DataInputStream(s1In);
String st = new String (dis.readUTF());
System.out.println(st);
dis.close();
s1In.close();
s1.close();
}
}

Why does Android allocate more memory than needed when loading images
|
<p>Folks, I don't <em>think</em> that this is a duplicate and is NOT one of those how do I avoid OOMs questions. This is a genuine quest for knowledge so hold off on those down votes please...</p>
<p>Imagine I have a JPEG of 500x500 pixels. I load it as ARGB_8888 which is as "bad as it gets".</p>
<p>I would expect Android to allocate 500x500x4 bytes = a little under 1MB however, look at a heap dump and you will see that Android allocates significantly more, often factors of 5-10 times greater. </p>
<p>You frequently see questions on here about OOMS where the stack trace shows a heap request of say 15MB and it is ALWAYS much larger than is required simply to hold the bytes of the image. The OP usually catches some downvotes then is bombarded with stock answers and comments about using less memory (thanks Romain!) and in scaling. I think there is more than meets the eye here.</p>
<p>Anybody know why this is?</p>
<p>If there is no apparent answer, I will put together an SSCCE if it helps.</p>
<p>PS. I assume that JPEG vs PNG etc is irrelevant since we're talking about the memory usage of the backing bitmap which is simply x times y times BPP - or am I being slow?</p>

Make subcategories in template script
|
<p>I really need help with a script i have bought, the script has some categories, but i also need sub categories, so i added an extra field in the table traffic_categories. The original traffic_categories has id and category, but i have added sub_id also, so if the category is a main category it has 0 in sub_id, but if the category is a sub category it has the main category id in the sub_id field.. Simple..</p>
<p>The problem is the script hava an advanced template system i can´t figure out how works.
Here is the script that gets the categories from mysql:</p>
<pre><code>$result = mysql_query('SELECT category FROM traffic_categories WHERE sub_id = 0 ORDER BY category ASC;');
$iCat=2;
$CONF['categories'] = array(); $TMPL['cats'] = '';
while(list($TMPL['cat']) = mysql_fetch_row($result)) {
$TMPL['cath'] = str_replace(' ', '+', $TMPL['cat']);
$TMPL['cats'] .= base::do_skin('menu/cats');
$CONF['categories'][] = $TMPL['cat'];
$TMPL['last'] = $iCat++ % 4 === 0 ? ' last' : '';
}
</code></pre>
<p>and here is cats.html:</p>
<pre><code><div class="one-fourth{$last}">
<h5><a href="/cat/{$cath}">{$cat}</a></h5>
<ul class="categoryList">
Here i want the subcategories--><li> - <a href=""></a></li>
</ul>
</div>
</code></pre>
<p>and in my frontpage.html where the categories will be showed is just {$cats}.</p>
<p>So if someone please can help me show the subcategories inside the list in cats.html where is have written "Here i want the subcategories-->", then i will be really glad, thanks.</p>

Check a list<string> for matches to a userdefined string
|
<p>I am having difficulties finding a suiteble way as to search a <code>List<></code> of strings i have for matches to a user specified string, I am not even sure i am going about it in the best way but what i got so far is:</p>
<pre><code> // This is the input string.
string input = userDefinedStr.ToLower(); //New variable and made into lower cases.
for (int i = 0; i < listBox1.Items.Count; i++)
{
if (listBox1.Items[i].ToString().IndexOf(input, stringComparison.OrdinalIgnoreCase) >= 0)
{
listBox1.SetSelected(i, true);
}
else
{
MessageBox.Show("Sorry, There was no matches found.", "An oupps happend!");
}
}
</code></pre>
<p>The problem is that there can be more the one string in the <code>List</code> that contains the userdefined string and i guess that the best way is actually to display all the <code>List<string></code> matches in the <code>listBox1</code> instead of just marking the first one found. </p>
<p>Or can it be done in another more effective way?!? </p>
<p>I am new to C# and coding in general so i dont feel like i know the best way, i have read so many articles and postings but i cant find the one pointing me in the right direction on this.</p>

$p = substr($perms, -1);
if ($count > 0 && $p >= 4)
print $url;
else
throw new \Exception(sprintf("File %s not accessible from Web!", $t));
}
</code></pre>
<p>This works most of the times but fails if, for instance, that file is in a Virtual Host directory or in a linked folder. Is there any better way? </p>

Android: layout background changes when resuming

<p>This is extremely odd behavior. When I load my activity for the first time, everything is fine... the layout background is transparent, as it should be, and which I specified in my xml file.</p>
<p>But when I go to another activity and return to the original activity, the background image is set to an image from my res/drawable directory. There is nowhere in my code that the image is referenced, and there is no call to change the background image anywhere. </p>
<p>I solved the problem by setting the background color to transparent in onResume(), but I cannot for the life of me, understand why it was doing this. Does anyone have any insights?</p>

PHP Form (post) Repeating input in a tabel
|
<p>I have a form (with post method) that takes the following input:<br>
- a certain name<br>
- a number<br>
- 3 checkboxes </p>
<p>All this input gets generated and calculated in a table.(html code within the php)<br>
Everything gets properly calculated and displayed in a table. </p>
<p><strong>So my question:</strong><br>
How do i make it possible after giving all those input to give in more input?<br>
Meaning i have made a hyperlink that goes back to the form itself (where i can give the input).<br>
So i can give in new data, and after submiting that again the table now contains 2 rows of values insteed of just 1. </p>
<p>Not really sure what exactly i need for this. (i use 2 php files, one for the form, then another one where the table gets displayed (and where all my calculations are placed).</p>

what exactly are built-in types in Python?
|
<p>I keep hearing "everything is an object" in both Ruby and Python world. Well, what are built-in functions then? Can someone explain that in layperson English?
For example: </p>
<pre><code>file=open(abc.txt)
</code></pre>
<p>open is a built-in function. Is it an object? Is it a method? Of what class?</p>
<p>How did we even end-up with <strong>functions in Python</strong> if everything is an object? I mean, shouldn't we be having class, objects, methods and attributes, instead of functions? I thought we had functions in languages like C. Python, Ruby and Java had classes, objects, attributes, methods.</p>
<p>In Ruby (<strong>irb</strong>), you could do something like <code>1.class</code> and this will give you <code>Fixnum</code>it will show you which class it belongs to. I don't seem to be able to do this in Python shell. Is there an equivalent?</p>
<p>FYI:</p>
<ul>
<li>I am using Python 2.7</li>
<li>relatively new to programming so please use layperson English. For instance, I read in one of the answers "But everything is an object in the sense that it can be assigned to a variable or passed as an argument to a function" --- no idea what that means.</li>

selecting from Jquery success result
|
<p>I'm trying to update a part of a page after the success of an asynchronous post.</p>
<p>So I have:</p>
<pre><code>success: function (data, status, xhr) {
var elementName = "#div" + gridName;
var findResult = $(data).find(elementName);
$(elementName).html($findResult);
</code></pre>
<p>Now when I view data the HTML looks like:</p>
<pre><code><div class="t-grid-header">
<div class="t-grid-header-wrap">
<table cellspacing="0">
</code></pre>
<p>but when I inspect the HTML from findResult it looks like:</p>
<pre><code><DIV class=t-grid-header>
<DIV class=t-grid-header-wrap>
<TABLE cellSpacing=0>
</code></pre>
<p>This is not 'good' Html so I can't use it. So how do I get good HTML. findResult.html() doesn't work because the call is too late. The conversion has already happened.</p>
<p>How do I proceed?</p>

jquery append to element when it appears with ajax displaytag
|
<p>Lets say I may (but also may not) have an element with class <code>order</code> in my DOM.
It maybe create on page load but also, after successful ajax request. My question is, how can I add some live event, that will append something to my element based on it class?</p>
<p>Flow would be like this:</p>
<p>1.Opening page, jQuery searchs for elements with class <code>order</code>, if found, appends something to them (for this question lets say its text <code>"text string"</code><br/>
2.I do an ajax request<br/>
3.After ajax request jQuery searchs again for class <code>order</code> and append if found</p>
<p>There is one condition, I DON'T want to trigger any function searching for elements after ajax request, I'd prefere some magic trick with <code>.live()</code> function, if it is possible of course.</p>
<p><strong>EDIT</strong> Exact problem</p>
<p>What I was really trying to achive, is appending an img to certain class within newly loaded DOM.
<br/>From the beginning:</p>
<ol>
<li><p>I tried to implementing sortable/paginable table with displaytag and ajax.</p></li>
<li><p>Then adding (also Ajax) search list filtering.</p></li>
<li><p>After table is reloaded with Ajax, append images (up or down icon depending on sorting type)</p></li>
</ol>
<p>See my answer for results</p>

How to determine the bit order allocation at compile time?
|
<p>as we all known, for some compilers:</p>
<pre><code>struct T{
char bits: 4; // 3:0
};
</code></pre>
<p>and for others:</p>
<pre><code>struct T{
char bits: 4; // 7:4
};
</code></pre>
<p>since this is not specified by the standard. ( I do think this (the arithmetic meaning) should be specified by the standard, and the actual physical allocation is another issue that can't be specified. )</p>
<p>However, I want my code to be more generic, so I tried:</p>
<pre><code>union helper{
unsigned char b:1;
unsigned char c;
constexpr helper(unsigned char i): c(i){}
};
constexpr int lsb_defined_at_top(){ return helper(1).b;}
enum{
LSB_AT_DEFINED_AT_TOP = lsb_defined_at_top()
};
</code></pre>
<p>but the compiler (gcc 4.7.2) complains:</p>
<p>error: accessing 'helper::b' member instead of initialized 'helper::c' member in constant expression</p>
<p>I wonder is there any way to determine this at compile time ...</p>

PHP Twitter Style Date
|
<p>I am wanting to format my date with a Twitter style format however all the examples only have the x hours ago. What I would like...if possible, is:</p>
<pre><code>- X min ago
- X hours ago
- Yesterday
- Thursday (or other days)
- 17 December
</code></pre>
<p>X min/hour ago and yesterday are pretty self explanatory but the day should be used if the date is greater than today and yesterday and the day falls within the current week (week starting Sunday).</p>
<p>The 17 December is if the date is greater than any day in the current week.</p>
<p>I am hoping this can be done. Cheers</p>

Script causing 500 Internal Server Error

<p>My site has been suffering "500 Internal Server Error" often of late, and host has advised that this bundle.css.php script might be the reason why ...</p>
<pre><code><?php
ob_start('ob_gzhandler');
header('Content-Type: text/css');
$files = split(",",$_GET['files']);
foreach($files as $key=>$val){
if(file_exists($val.'.css')){

}else{
echo "\n\n/*** File \"$val\" does not exist. ***/\n\n";
}
}
?>
</code></pre>
<p>In the words of my host ...</p>
<p>"It is trying to buffer all of output into ob_gzhandler. It is taking a very insecure list of parameters passed in GET variable 'files', and is then trying to include those files into the output. I'm not sure exactly what list of parameters is being passed, but I suspect there is a bug somewhere in your scripts that is passing a large array of file names to this script, and thus trying to build a buffered object that is too large."</p>
<p>This is well beyond my expertise, so any advice to fix the problem would be much appreciated. Many thanks.</p>

Getting screen height before first display?

<p>I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided.</p>
<p>How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows,</p>

<p>i.e. an external function ("doSomething") which has $(document).ready inside it. I'm confused because isn't the code under $(document).ready triggered when the DOM is loaded ? Its like having an event handler inside a function (?). Does this form of code make sense to anyone ? Thanks.</p>

Calculating an average, minimum, and maximum, from an imported file (.txt)

<p>I have a project where I need to read in data from a .txt file and run some calculations on it. No arrays allowed.</p>

<p>firstname lastname age scores</p>
<p>example</p>
<p>Brian Moore 55 8 4 3 6 13 2 4 7</p>
<p>I need to print the data with just the initials of the person (first two letters of each name), and find an average for the scores.</p>
<p>This is what I started with, but I am really just stumped at this point, which means getting started. I feel like if I can get one line down, it's just a matter of making loops to create the rest.</p>

int scoreSum = 1;
while (inputOne.hasNext()) {
int scoreList = inputOne.nextInt();
System.out.println(scoreList);
scoreSum = scoreSum + scoreList;
scoreCounter++;

ASP Security Exception: Same but different
|
<p>Raking my brain and I have tried many of the "solutions" found online. Basically we are demoing this application from a vendor and the initial install worked fine. The application is actually four different applications. On our Windows server we have our main site, with four applications inside of it for the vendor. All of these were using the default application pool. Everything was working.</p>
<p>They asked us to updated the software and things went to hell. Updating involved deleting all the old files and replacing them with the new ones they sent us and then updating our SQL database. We we finished two of the applications had the error:</p>
<pre><code>Exception Details: System.Security.SecurityException: Request for the permission of type
'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' failed.
</code></pre>
<p>I have found many answers regarding this. Change the Load User Profile to ture, tried that, Unblock all the dll files, tried that. Mess with the trust level, tried that. I have since separated the applications into their own pools (at the advice of the vendor but they seem to have no clue) and after messing with it a ton, I now have three of the applications running, oddly enough one of the ones initially running is the one that is not running. The thing is the application was running initially, all we did was updated the files to newer versions.</p>
<p>My question I guess is where is the System.Web.AspNetHostingPermission called? Is that just a general level Asp application thing? I am pulling out my hair about this and we might just have to tell the vendor to take their product elsewhere if we can't get it running, but I am 99% sure it's a server setup issue. Thing is, I've never dealt with software where the update process is, delete all your files and replace them with the ones in this zip file.</p>
<p>Any thoughts on this. I feel like I have tried most of the obvious solutions but need some deeper thoughts.</p>

Can I have an application always open on Android?
|
<p>I don't know much about Android multitasking but I thought I'd ask the question before I attempt my project.</p>
<p>Is there a way I can program an Android application (aimed at Android 4.0+ only) to always be open in the background and keep all the network connections alive and the UI "drawn" so that when I open it, it ALWAYS opens instantly and I can use it instantly even if the tablet is doing something else?</p>
<p>Thanks.</p>

Assigning values to elements of list
|
<p>When I have a for loop:</p>
<pre><code>for row in list:
row = something_or_other
</code></pre>
<p>It seems that sometimes I can assign a value (or append/extend etc.) directly to <code>row</code> and the <code>list</code> changes accordingly, and sometimes I have to do something roundabout like:</p>
<pre><code>for row in list:
list[list.index(row)] = something_or_other
</code></pre>
<p>What gives?!?</p>

Replacing tokens in a string from an array
|
<p>Let's say I have a string</p>
<blockquote>
<p>This $0 is $2 $1. Still, \$$3 is a lot to pay for a puppy.</p>
</blockquote>
<p>and an array of replacements</p>
<pre><code>array('puppy', 'cute', 'ridiculously', '1300')
</code></pre>
<p>What would be the cleanest way to replace the tokens in the string with the corresponding items in the array, letting me backslash-escape the token character (in this case <code>$</code>)? I also want to replace unmatched tokens with the empty string.</p>
