C++: Objects allocated on heap
|
<p>When we create an object using <em>new</em> it is allocated on the heap. But, what happens to the members of the class that we are instantiating? For example, </p>
<pre><code>class foo {
Bar x;
Bar *y;
foo() {
x = 10;
y = new Bar();
}
}
</code></pre>
<p>Here, x is an object while y is an instance of Bar. Are they both allocated on the heap? So if an object of foo <em>F</em> is created locally inside a method, what will happen to <em>y</em> when F goes out of scope?</p>
<p>Also, if <em>F</em> is created on the heap, when will we conclude that <em>F</em> is dangling (no one pointing to it)? Because, there may be no references to F but there may be references to <em>Y</em>.</p>

Comparing Java Beans with BeanComparator
|
<p>I am trying to compare 2 beans of the same class and determine what part of the beans (if any) do not match. This may include beans with internally nested beans of another class, but for the most part the classes will be matching. Basically I want to derive the first class from the database and compare it with a new copy which will inevitably update the data in the database that is not already the same as whats currently in there.</p>
<p>So basically I will need to loop through each variable in the bean and compare it with bean 2. If it matches...move onto the next. If it does not match, return the index of the variable so I know what field to update in the database. </p>
<p>Is this something I can do with apache commons BeanComparator? Or will I have to come up with my own custom tool?</p>

How should I execute Javascript files independently?
|
<p>Let's say I had an array of Javascript file names:</p>
<pre><code>["funScriptStuff.js", "jQuery.js", "dojo.js", "scriptyScript.js"]
</code></pre>
<p>how could I execute them independently of each other? </p>
<p>For example, let's suppose one script did some evil stuff like </p>
<pre><code>var undefined = true;
var window = "Windows 98";
</code></pre>
<p>and another script had code that relied on these global variables being unsabotaged</p>
<pre><code>if (a !== undefined) {
window.open(url);
}
</code></pre>
<p>if the first script ran first, it would ruin everything in the second one. Without changing anything in these script files, how can I run them independently of each other to prevent them from messing each other up?</p>
<p><strong>EDIT:</strong> I am not asking what Javascript patterns to use to prevent namespace collisions, like wrapping my code in a big closure and so forth. I know about those. I'm trying to create an environment where you can run arbitrary scripts that I have no control over without them stepping on each other's toes.</p>

Javascript, Do While Loop multiple options
|
<p>Can you please explain and show the right answer:</p>
<pre><code><p id="show"></p>
<script>
var a = "word1";
var b = "word2";
do {
color = prompt("Write a word1 or word2 to get out of loop", "");
} while (color != a || color != b);
document.getElementById("show").innerHTML=color;
</script>
</code></pre>
<p>It works when I delete 'b' option and leave as is only with 'a' option. So how can I use it for multiple options? Also, if you have a solution to keep it simple if I had 15 options for example, it will be great!</p>

Android: How to check if a DB field is blank and, if so, add a value like "Unnamed Record"?
|
<p>I am working off the Android Notepad Tutorial as a base. The problem is that when someone creates a record with a null name field, it shows up as a blank space in the listview and is unclickable, and therefore undeletable from the list. </p>
<p>I would like to have the program check for a null "name" field and replace it with the string "Unnamed Record" so that it comes up appropriately in the listview. Everything that I have tried so far has not worked correctly.</p>
<p>Another possible solution might be the give the name field an initial value of "Unnamed Record" but I am not sure that this would be effective.</p>
<p>Thanks.</p>

Best scaleable way to find many keywords in a large amount of text?
|
<p>Ever few minutes around 500 paragraphs are supposed to be submitted to the database in a table called "Content" (this number will go to over 2,500 in a few months).
There is another table called "Keywords" which has over 4,000 rows (and is expected to grow to over 10,000).</p>
<pre><code>Keywords
+------------+-------------------+
| Keyword_id | keyword |
+------------+-------------------+
| 1 | "Venture Capital" |
| 2 | "Financing" |
+------------+-------------------+
</code></pre>
<p>The question is: <strong>What is the best way to scale a solution where each keyword is cross-referenced among an incoming paragraphs of text to see if there is a match?</strong></p>
<p>Since I'm not concerned about where in the paragraph there is a match (my only concern is that there IS a match);
<code>if(preg_match()){}</code> could possibly work but even at the low-end that's 2,000,000 times you're running over a paragraph searching for a keyword.
Plus, correct me if I'm wrong, preg_match is pretty expensive.</p>
<p>One of the possibilites that crossed my mind was to keep an array of the keywords in the cache instead of having to call on the DB for every row.
That would definitely help speed things up I think.</p>
<p>I'm not concerned with this being only in PHP.
If this section of the application needs to be in Python (correct me if I'm wrong, but I hear Python is a lot less expensive at parsing text), then I'm all ears.</p>

Issue with sending form in jquery

<p>I am working on a function that lets people log in to their accounts and the form should be sent without reloading the page. The problem is, with my current code the form values are not sent for some reason. What is wrong with my code?</p>
<p><strong>Jquery</strong></p>
<pre><code><script type="text/javascript">
$(document).ready(function() {
$('#form form').submit(function(){
$("#form :input").attr("disabled", true);

$("#form :input").attr("disabled", false);
});
return false;

Reading lines from Python queues
|
<p>I'm dipping my toes into Python threading. I've created a supplier thread that returns me character/line data from a *nix (serial) /dev via a Queue.</p>
<p>As an exercise, I would like to consume the data from the queue one line at a time (using '\n' as the line terminator).</p>
<p>My current (simplistic) solution is to put() only 1 character at a time into the queue, so the consumer will only get() one character at a time. (Is this a safe assumption?) This approach currently allows me to do the following:</p>
<pre><code>...
return_buffer = []
while True:
rcv_data = queue.get(block=True)
return_buffer.append(rcv_data)
if rcv_data == "\n":
return return_buffer
</code></pre>
<p>This seems to be working, but I can definitely cause it to fail when I put() 2 characters at a time.</p>
<p>I would like to make the receive logic more generic and able to handle multi-character put()s.</p>
<p>My next approach would be to rcv_data.partition("\n"), putting the "remainder" in yet another buffer/list, but that will require juggling the temporary buffer alongside the queue.
(I guess another approach would be to only put() one line at a time, but where's the fun in that?)</p>
<p>Is there a more elegant way to read from a queue one line at a time?</p>

How to show number of unpublished articles?
|
<p>I recently started an article directory using wordpress, and theme by dimox and plugin and plugin by artilcesss dot com.</p>
<p>On homepage it shows number registered authors and and published posts. </p>
<p>It is using %2$s for registered authors and %1$s for number of published articles in main index template.</p>
<p>I have so many unpublished articles too, so my question is that is there any way to show the number of unpublished articles (only counts) on the homepage? </p>
<p>Update:</p>
<p>thanks for the answers, it is useful for users like me, I am not expert in this, here is the code.</p>
<pre><code><p><?php global $numposts, $users; printf(__('We have <strong>%2$s</strong> registered authors and <strong>%1$s</strong> published articles till the date.', 'article-directory'), $numposts, $users); ?></p>
</code></pre>
<p>And this will show the output:</p>
<p>We have 24 registered authors and 43 published articles till the date.</p>
<p>(24 and 43 numbers are current statistics)</p>

JQuery Offset problem
|
<p>I have a div on page load has the css "Display:none; position:absolute"</p>
<p>There is a jQuery click event on a label that shows this div</p>
<p>Before I do .fadeIn() on I find the width and height of the window and set the offset of the div to try place to div in the centre of the screen. </p>
<p>This div also has a close image that has a jQuery click event that sets the div to fade out</p>
<p>The first time I open the div the div is positioned correctly on the screen, if I close the div and open it the div moves further right and down. It keeps on doing this until I do a full page refresh</p>

<p>It's not the easiest to read, but it basically takes the count of the list and subtracts 1 from it, and uses that for the IndexOf method to get the last item that was added to the list.</p>

Visual studio 2010 web application deployment

When I try to compile my web app, by clicking on "publish website" it tells me "Publish succeeded" but the deployment folder is empty. I even checked to see whether I have syntax errors. I have none, that I could locate. I also did some extensive googling but no satisfactory answer. What is causing this? Am I missing something here? Is it a bug from Visual Studio 2010? Your help would be very much appreciated.</p>

<p>I was wondering if there is any advanced library in Python which could let me do all of this. Please give me suggestions.

When I remove the tableView or use window base template, it kept crashing with the console stated the same error, something like it couldn't find this entity name.

This value I then set to a global variable defined at the start of my script so I can reference the value again and again... the value with determine the user language for instance.</p>
<pre><code>// define my global var at the top of my script..
var globalOpCo = "";
// I then try to give this a value in the next function I call...
$.ajax({

ASP.NET: Thread-safety in a file-based database
|
<p>I have worked a bit with ASP.NET before. I was using a MS SQL server to store and retrieve data to display in some dynamic pages in one project I started to learn ASP.NET a bit. Now I am about to start a new project but this time I would like to store the data in a file-based database , like say, an Access file. This project is also a hobby project and I'm not afraid of the scaling problem because perhaps only 3 users will be using the application at the same time and no be data traffic will be expected.</p>
<p>Now , about my question: using a MS SQL database there is no problem with several users reading-writing to the Db at the same time because the DB engine will take care of this, but using a file-based database with ADO.NET will be a problem in that case, am I right? </p>
<p>What I mean, do I need to take care of multiuser synchronization myself (using some synchronization mechanism, lock, mutex, whatever) to guarantee thread safety when working with the database or does ADO.NET takes care of that as well?</p>
<p>Should I use perhaps a singleton class for the data layer? </p>

Using in range(..) in an if-else statment
|
<p>python 2.7</p>
<p>Is it possible to do this:</p>
<pre><code>print "Enter a number between 1 and 10:"
number = raw_input("> ")
if number in range(1, 5):
print "You entered a number in the range of 1 to 5"
elif number in range(6, 10):
print "You entered a number in the range of 6 to 10"
else:
print "Your number wasn't in the correct range"
</code></pre>
<p>I find if I put a number between 1 to 10 it always falls to the else statement.</p>
<p>Is this an incorrect use of in range in an if-else statement?</p>
<p>Many thanks in advance,</p>

<p>In PHP I see that</p>
<pre><code>$_SERVER['HTTP_REFERER']

<p>Or does it only work if a user clicks on a link that takes them to page B?</p>

Cloning android source code repo into a different directory
|
<p>I followed instructions at <a href="http://source.android.com/source/download.html" rel="nofollow">http://source.android.com/source/download.html</a> to build android source code on Mac OS X. Created case-sensitive image of size 8.5 GB and gave make for 'full-eng' target in lunch command, After sometime got this error complaining about insufficient disk space :</p>
<pre><code>prebuilt/darwin-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-ar: out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/libwebcore.a: No space left on device

make: *** Deleting file `out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/libwebcore.a'
</code></pre>
<p>Is 8.5GB not sufficient to build, instructions say 8Gig is enough.Did i miss something.?</p>
<p>Now I want to create another case-sensitive image of size say 12GB and build it, can simple copy of files from 8.5GB volume to 12GB volume work? Or is there any special command (git clone or something.. sorry noob to git) to copy the entire repo so that all git projects will copy safely.</p>

jQuery if javascript is disabled/enabled?
|
<p>I was <a href="http://tutsplus.com/lesson/slides-and-structure/" rel="nofollow">watching this video tutorial</a> and I noticed he said that he's added this: </p>
<p><code>$('html').addClass('js');</code> </p>
<p>He said that if javascript is disabled, then the class won't show, but if it is enabled, the class will show. I don't understand how that works. How does jQuery know if JS is enabled, and to apply a certain class when JS is enabled/disabled? There's no if statement. I'm a tad bit confused. </p>
<p>"If HTML has a class of JS, javascript is available, if not, JS is not available". I don't understand that. </p>
<p>He also mentioned a "JavaScript hook"..?</p>
<p>Watch from 2:30 to 3:40, it's where he explains it but I don't understand.</p>
<p>Thanks!</p>
