382,382 | <p>Is there any way in JavaScript how to find out user clicked through the same domain 2 or more times? </p>
<p>I need to popup a window after user clicked anywhere on the site for 3 times. I know how to do it after one click - with <code>document.referrer</code> or <code>addEventListener</code>, but then I'm lost.</p>
<p>I need something that will capture all click events (not only links) and count them. </p>

382,383 | <p>I am working on an ASP.NET page that we, in code impersonate the requesting user. We are using the following code to start impersonating.</p>
<pre><code>Dim impersonationContext As System.Security.Principal.WindowsImpersonationContext
Dim currentWindowsIdentity As System.Security.Principal.WindowsIdentity
currentWindowsIdentity = CType(User.Identity, System.Security.Principal.WindowsIdentity)
impersonationContext = currentWindowsIdentity.Impersonate()
</code></pre>
<p>After this we have validated that the application is running under the proper context by calling:</p>
<pre><code>System.Security.Principal.WindowsIdentity.GetCurrent().Name
</code></pre>
<p>This returns the proper identity of the user, and file access and other items appear to be using their account. However when using the Microsoft Application Data Application Block SqlHelper class to call out to a database using a trusted connection authentication fails for the "NT AUTHORITY\ANONYMOUS LOGON" user.</p>
<p>We can re-validate after the failure that the current identity is still our desired account and NOT the ANONYMOUS LOGIN account.</p>
<p>Does anyone have an idea why this is? Or more specifically how we can get around it?</p>
<p><strong>Edit</strong>
Some additional information about how the calls from these pages work.</p>
<p>We do the impersonate call from the .aspx page.</p>
<p>After we impersonate we call out to a "business logic" assembly that is referecned.</p>
<p>We know that the context identity is still correct here.</p>
<p>After that, the "business logic" assembly calls another assembly that actually executes the trusted connection call. We cannot modify this "data access" assembly, the authentication exception is reported by this assembly as well.</p>

382,449 | <p><strong>Closed as exact duplicate of <a href="https://stackoverflow.com/questions/228164/on-design-patterns-when-to-use-the-singleton">this question</a>. But reopened, as the other Singleton questions are for general use and not use for DB access</strong></p>
<p>I was thinking of making an internal data access class a Singleton but couldn't convince myself on the choice mainly because the class has no state except for local variables in its methods. </p>
<p>What is the purpose of designing such classes to be Singletons after all?<br>
Is it warranting sequential access to the database which is not convincing since most modern databases could handle concurrency well?<br>
Is it the ability to use a single connection repeatedly which could be taken care of through connection pooling?
Or Is it saving memory by running a single instance? </p>
<p>Please enlighten me on this one. </p>

382,464 | <p>When I upload a file to a site using the ASP:File control the FileName property is different in IE and Firefox. In Firefox, it just provides the name of the file, but IE provides the full path to the file.</p>
<p>I have worked around this by adding the code:</p>
<pre><code>Dim FileName As String = file.FileName
If FileName.LastIndexOf("\") > 0 Then
FileName = FileName.Substring(FileName.LastIndexOf("\") + 1)
End If
</code></pre>
<p>But I'm not sure why that would be different between the different browsers. Does anyone know the reason for this?</p>
<p>Thanks.</p>

382,466 | <p>I never actually thought I'd run into speed-issues with python, but I have. I'm trying to compare really big lists of dictionaries to each other based on the dictionary values. I compare two lists, with the first like so</p>
<pre><code>biglist1=[{'transaction':'somevalue', 'id':'somevalue', 'date':'somevalue' ...}, {'transactio':'somevalue', 'id':'somevalue', 'date':'somevalue' ...}, ...]
</code></pre>
<p>With 'somevalue' standing for a user-generated string, int or decimal. Now, the second list is pretty similar, except the id-values are always empty, as they have not been assigned yet.</p>
<pre><code>biglist2=[{'transaction':'somevalue', 'id':'', 'date':'somevalue' ...}, {'transactio':'somevalue', 'id':'', 'date':'somevalue' ...}, ...]
</code></pre>
<p>So I want to get a list of the dictionaries in biglist2 that match the dictionaries in biglist1 for all other keys <em>except</em> id.</p>
<p>I've been doing </p>
<pre><code>for item in biglist2:
for transaction in biglist1:
if item['transaction'] == transaction['transaction']:
list_transactionnamematches.append(transaction)
for item in biglist2:
for transaction in list_transactionnamematches:
if item['date'] == transaction['date']:
list_transactionnamematches.append(transaction)
</code></pre>
<p>... and so on, not comparing id values, until I get a final list of matches. Since the lists can be really big (around 3000+ items each), this takes quite some time for python to loop through.</p>
<p>I'm guessing this isn't really how this kind of comparison should be done. Any ideas?</p>

382,478 | <p>I've read a lot recently about how writing multi-threaded apps is a huge pain in the neck, and have learned enough about the topic to understand, at least at some level, why it is so. </p>
<p>I've read that using functional programming techniques can help alleviate some of this pain, but I've never seen a simple example of functional code that is concurrent. So, what are some alternatives to using threads? At least, what are some ways to abstract them away so you needn't think about things like locking and whether a particular library's objects are thread-safe.</p>
<p>I know Google's MapReduce is supposed to help with the problem, but I haven't seen a succinct explanation of it.</p>
<p>Although I'm giving a specific example below, I'm more curious of general techniques than solving this specific problem (using the example to help illustrate other techniques would be helpful though). </p>
<p>I came to the question when I wrote a simple web crawler as a learning exercise. It works pretty well, but it is slow. Most of the bottleneck comes from downloading pages. It is currently single threaded, and thus only downloads a single page at a time. Thus, if the pages can be downloaded concurrently, it would speed things up dramatically, even if the crawler ran on a single processor machine. I looked into using threads to solve the issue, but they scare me. Any suggestions on how to add concurrency to this type of problem without unleashing a terrible threading nightmare?</p>

382,479 | <p>I am using log4net in my .NET 3.5 console application and would like the log messages I generate to be seen in both the console standard out and the RollingFileAppender. The file output is working like a charm, but I am seeing a stream of status messages flowing to the console standard out when I execute. I would like to skip all the status information and only see the same messages I am programmatically generating to the log file.</p>
<p>Here is an example of what I see after I run my app:</p>
<pre><code>log4net: XmlHierarchyConfigurator: Configuration update mode [Merge].
log4net: XmlHierarchyConfigurator: Logger [root] Level string is [DEBUG].
log4net: XmlHierarchyConfigurator: Logger [root] level set to [name="DEBUG",value=30000].
log4net: XmlHierarchyConfigurator: Loading Appender [Console] type: [log4net.Appender.ConsoleAppender]
log4net: PatternParser: Converter [message] Option [] Format [min=-1,max=2147483647,leftAlign=False]
</code></pre>
<p>and it keeps on going until it describes the whole instantiation of the logger object.</p>
<p>How do I turn this off? Can I? I've tried all sorts of config file settings, but nothing makes these go away! Grrr...</p>

382,480 | <p>Given a variable <code>foo</code> of type <code>FooClass*</code> and a member variable in that class named <code>bar</code>, is the distance between <code>foo</code> and <code>&(foo->bar)</code> the same in any situation with some constraints:</p>
<ol>
<li><p><code>FooClass</code> is a non-POD type.</p></li>
<li><p>We know that <code>foo</code> will always point to an instance of <code>FooClass</code>, and not some subtype of it.</p></li>
<li><p>We only care about behaviour under a single compiler and a single compilation; that is, the value this may result in under gcc is never used in code compiled with MSVC, and it is never saved to be re-used between compilations. It is computed in the binary and used in the binary, and that is it.</p></li>
<li><p>We don't use a custom <code>new</code>, although some instances of the class may be stack-allocated and some heap-allocated.</p></li>
<li><p>There is no explicit <code>ctor</code> for <code>FooClass</code>; it relies upon the compiler-generated one (and each of the fields in <code>FooClass</code> is either POD or default-constructable).</p></li>
</ol>
<p>I can't find a guarantee either way on this in the standard (nor did I expect to), but my rudimentary testing with gcc leads me to believe that it will always be the case there. I also know that this guarantee is made for POD-types, but let us assume this type can't be POD.</p>
<p><strong>An update/clarification:</strong> this is just for a single compilation of a single binary; the calculated offsets will never leave that single execution. Basically, I want to be able to uniquely identify the fields of a class in a static map and then be able to lookup into that map for some macro/template/EVIL trickery. It is merely for my own amusement, and no life support machines will rely on this code.</p>

<p>I use a "Globals" record set up in the main form to store all global vars, have one element of that called Globals.AppInitialized (boolean), and set it to False in the Initialization section of the main form. </p>
<p>At the main form's OnShow event (all forms are created by then), I test Globals.AppInitialized; if it's false, I run my "Initialization" stuff, and then finish by setting Globals.AppInitialized := True.</p>
<p>This seems to work pretty well, but is it the best approach? Looking for insight from others' experience, ideas and opinions. TIA..</p>

382,576 | <p>I have a .xib file containing a UIView and 2 UILabel subviews linked to a class named Note with outlets assigned to each label appropriately, the definition for this class contains the following.</p>
<pre><code>@interface Note : UIView {
IBOutlet UILabel *time;
IBOutlet UILabel *content;
}
</code></pre>
<p>I'm constructing this with the following code</p>
<pre><code>NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"Note" owner:self options:nil];
note = [nibViews lastObject];
[self addSubview:note];
</code></pre>
<p>Now, in my Note class dealloc phase, I'm not releasing either time or content, but I'm wondering if I should? </p>
<pre><code>- (void)dealloc {
[super dealloc];
}
</code></pre>
<p>I'm assuming I don't because I'm not explicitly retaining these objects anywhere in my code, and I don't synthesize these into getter/setters. But I don't know enough about nib unarchiving to know whether I should be releasing these in my dealloc phase or not?</p>

set par3=%3
set therest=%???
echo the script is %0
echo Parameter 1 is %par1%

<p>Running <code>mybatch opt1 opt2 opt3 opt4 opt5 ...opt20</code> would yield:</p>

Parameter 1 is opt1
Parameter 2 is opt2
Parameter 3 is opt3

382,602 | <p>Quick design question.</p>
<p>ClassA has a method called DoSomething(args)</p>
<p>In DoSomething(), before it can actually do something, it needs to do some preparatory work with args. I believe this should be encapsulated within ClassA, (as opposed to doing the prep work outside and passing it in) as nothing else needs to know that this prep work is required to DoSomething.</p>
<p>However, it's where the actual preparatory work code belongs that is making me think.</p>
<p>The preparatory work in my particular example is to create a list of items, which satisfy a certain condition, from args.</p>
<p>My hunch is that I should create a new class, ListOfStuff, which takes args in its constructor and put this preparatory work here.</p>
<p>From a TDD-perspective, I think this is the right choice. We can then unit test ListOfStuff til our heart is content. If we had put the preparatory work in a private method of ClassA, we'd have only been able to indirectly test it through testing DoSomething().</p>
<p>But is this overkill? Since adopting the TDD and DI approach, I've seen the number of classes that I write multiply - should I be worried?</p>
<p>Ta.</p>

382,603 | <p>So in Ruby there is a trick to specify infinity:</p>
<pre><code>1.0/0
=> Infinity
</code></pre>
<p>I believe in Python you can do something like this</p>
<pre><code>float('inf')
</code></pre>
<p>These are just examples though, I'm sure most languages have infinity in some capacity. When would you actually use this construct in the real world? Why would using it in a range be better than just using a boolean expression? For instance</p>
<pre><code>(0..1.0/0).include?(number) == (number >= 0) # True for all values of number
=> true
</code></pre>
<p>To summarize, what I'm looking for is a real world reason to use Infinity.</p>
<p><strong>EDIT</strong>: I'm looking for real world code. It's all well and good to say this is when you "could" use it, when have people <em>actually</em> used it.</p>

<p>This <code>@measured</code> directive doesn't seem to work with raw python. What is it?</p>

382,633 | <p>We are using <a href="http://checkstyle.sourceforge.net/index.html" rel="nofollow noreferrer">CheckStyle</a> to enforce our style standards. One of the style rules we opted to include was the <em>NeedBraces</em> module.</p>
<p><em><a href="http://checkstyle.sourceforge.net/config_blocks.html#NeedBraces" rel="nofollow noreferrer">NeedBraces</a></em> specifies that every block type statement (such as <code>if</code>, <code>else</code>, <code>for</code>) must have opening and closing curly braces. However, as far as I can tell it isn't working entirely correctly.</p>
<p>This example will trigger a CheckStyle error.</p>
<pre><code> if (true)
{
System.out.println("20");
}
else
System.out.println("30");
</code></pre>
<p>Because the else case doesn't have braces. However, the next example fails to trigger a CheckStyle error.</p>
<pre><code> if (true)
{
System.out.println("20");
}
else
if (true)
{
System.out.println("30");
}
</code></pre>
<p>This should have failed because of the missing braces on the else case, but checkstyle lets it pass. After double checking the documentation, I can't find any reason why this isn't working right. </p>
<p>So...
<strong>Can the CheckStyle module "NeedBraces" work with nested if/else blocks?</strong>
Any ideas?</p>

<p>The answer to this question begs <a href="https://stackoverflow.com/questions/387008/is-there-a-checkstyle-rule-to-force-if-else-keywords-to-be-on-the-same-line-in">another question</a>: is there a rule to flag the above undesirable code as a violation?</p>

382,675 | <p>I am looking for a way to position a div (it would be a pop-up that would be activated by a user hovering and/or clicking much like lightbox) over an a split iframe where the top iframe is content from my server and the bottom iframe is content from another server. Like this:</p>
<pre>
----------------------------------------
| |
| Upper |
| |
| ------------------- |
| | DIV | |
--------- -------|
| | | |
| -------------------- |
| |
| Lower |
| |
----------------------------------------
</pre>
<p>Basically it looks like a box that is split horizontally between the top (upper) and bottom (lower; the external content) and a DIV that hovers over the two so there is overlap on both the top and the bottom.</p>
<p>By the way, I also posted another question re: ajax versus iframes for external content and what I should use in this instance. So the lower (external content) doesn't necessarily have to be an iframe depending on the answer to that.</p>

382,711 | <p>I was looking at sql inner queries (bit like the sql equivalent of a C# anon method), and was wondering, can I return more than one value from a query?</p>
<p>For example, return the number of rows in a table as one output value, and also, as another output value, return the distinct number of rows?</p>
<p>Also, how does distinct work? Is this based on whether one field may be the same as another (thus classified as "distinct")?</p>
<p>I am using Sql Server 2005. Would there be a performance penalty if I return one value from one query, rather than two from one query?</p>

<pre><code>replace -x "must " A2input.txt
replace -x " a" -f -s ## A2input.txt
replace -x to -s ## -a A2input.txt
replace -x faith -f "unequivocal" A2input.txt
</code></pre>
<p>And it'd be nice if I could just alias it to something short and simple like "a", "b", "c", "d", etc...</p>
<p>However, some of those arguments have a quote, which is messing up the alias. Does anyone know how to actually escape the double quotes? I've tried things like '\"' and \" but nothing seems to work. </p>
<p>I'm using tcsh as my shell.</p>

382,797 | <p>I teach a one semester University course in systems analysis and design. Topics include design patterns, UML, OOP, software development lifecycles, and the history, benefits and drawbacks of various methodologies (such as Agile/SCRUM/BDUF/Waterfall.)</p>
<p>Students who enter the course should have <em>some</em> exposure to programming, but in reality I've seen everything from people who are highly fluent in one or two modern languages to those who can barely pass the FizzBuzz test. </p>
<p>My question is two-fold: how much programming experience do you think students need before exposure to these topics (or do you think they should learn them before they learn to code), and second, what do you feel would be fair and appropriate ways to pre-test them at the start of the class, knowing that there is no consistent language or platform in their background?</p>

382,880 | <p>My team is working on a conversion project to convert one product (but with many facets) from VB6 to .Net (we have over ~300k LOC). Before I got on board, the decision was made that regardless of the location of the assembly, or folder structure, all classes / structs will be in one namespace:</p>
<p>.</p>
<p>They even go as far as changing auto-generated application settings designer code, resource designer code, and such to force uniformity. How do I convince them that namespace use is good? What is the proper use of namespace and what are the pros and cons? I guess I am having a tough time understanding why my colleagues would go through so much hassle to save a few using lines. Any external, reputable references to support your argument would be much appreciated. Please help!</p>

382,993 | <p>A colleague of mine recently got bitten badly by writing out of bounds to a static array on the stack (he added an element to it without increasing the array size). Shouldn't the compiler catch this kind of error? The following code compiles cleanly with gcc, even with the <code>-Wall -Wextra</code> options, and yet it is clearly erroneous:</p>
<pre><code>int main(void)
{
int a[10];
a[13] = 3; // oops, overwrote the return address
return 0;
}
</code></pre>
<p>I'm positive that this is undefined behavior, although I can't find an excerpt from the C99 standard saying so at the moment. But in the simplest case, where the size of an array is known as compile time and the indices are known at compile time, shouldn't the compiler emit a warning at the very least?</p>

382,998 | <p>Does anyone know exactly what Windows XP does when you click "Repair" on a network connection? I'd like to do the same programmatically or from a command line.</p>
<p>I did a Google search and found <a href="http://windowsitpro.com/article/articleid/41060/what-actions-occur-when-i-click-repair-on-a-network-connection-in-windows-xp-and-later.html" rel="nofollow noreferrer">this article</a>, which has a good explanation, but I don't think it's complete. I can reliably reproduce a condition where I lose network connectivity and clicking the Repair button fixes the problem, but running the commands in that article does not.</p>

383,026 | <p>I find this comes up a lot, and I'm not sure the best way to approach it. </p>
<p><strong>The question I have is how to make the decision between using foreign keys to lookup tables, or using lookup table values directly in the tables requesting it, avoiding the lookup table relationship completely.</strong></p>
<p>Points to keep in mind:</p>
<ul>
<li><p>With the second method you would
need to do mass updates to all
records referencing the data if it
is changed in the lookup table.</p></li>
<li><p>This is focused more
towards tables that have a lot of
the column's referencing many lookup
tables.Therefore lots of foreign
keys means a lot of
joins every time you query the
table.</p></li>
<li>This data would be coming from drop
down lists which would be pulled
from the lookup tables. In order to match up data when reloading, the values need to be in the existing list (<em>related to the first point</em>).</li>
</ul>
<p>Is there a best practice here, or any key points to consider?</p>

383,058 | <p>I am using Jruby and rails 2.2.2. My problem is I have a migration that is not being correctly written to the database schema.</p>
<p>Here is my migration: </p>
<pre><code>class CreateNotes < ActiveRecord::Migration
def self.up
create_table(:notes, :options => 'ENGINE=MyISAM') do |t|
t.string :title
t.text :body
t.timestamps
end
execute "alter table notes ADD FULLTEXT(title, body)"
end
</code></pre>
<p>Here is what it produces on in schema.rb</p>
<pre><code>create_table "notes", :force => true do |t|
t.string "title"
t.text "body"
t.datetime "created_at"
t.datetime "updated_at"
end
add_index "notes", ["title", "body"], :name => "title"
</code></pre>
<p>I have two question:</p>
<ul>
<li>How do I get <code>'ENGINE=MyISAM'</code> into the schema?</li>
<li>Why did my execute statement become <code>add_index "notes", ["title", "body"], :name => "title"</code>? and how do I force migrations to leave it as an execute statement?</li>
</ul>
<p>Thanks to Christian Lescuyer for the answer. However, when I tried this nothing changed. I uncommented the config.active_record... line but, my schema has not changed. I have tried this in jruby and on ruby 1.8.6 with rails 2.2.2 and edge rails and there is not changes in the schema. Can anybody tell me what I am doing wrong?</p>

383,101 | <p>i'm having a hard time with Xcode; for some reason, it just won't let me pass a variable from one view controller class to another. It should work, i was basically just copying/pasting from my other classes (it works on all of them... except this one). I've been at it all night long, tried everything i could think of and still it remains.</p>
<p>Here's the view controller class where I'm making the call:</p>
<h2>ResultadosViewController.h:</h2>
<pre><code>#import <UIKit/UIKit.h>
#import "Filme.h"
#import "Festival.h"
#import "Top10Discos.h"
#import "Peca.h"
@class DetalhesViewController;
@interface ResultadosViewController : UIViewController
{
// Navegation
DetalhesViewController *dvc;
BOOL isViewPushed;
// What i'd really like to pass lol
NSArray *array_resultados;
}
@property (nonatomic, retain) NSArray *array_resultados;
@property (nonatomic, readwrite) BOOL isViewPushed;
@end*
</code></pre>
<h2>ResultadosViewController.m:</h2>
<pre><code>#import "ResultadosViewController.h"
#import "DetalhesViewController.h"
#import "Filme.h"
#import "Peca.h"
#import "Top10Discos.h"
#import "Festival.h"
@implementation ResultadosViewController
@synthesize isViewPushed, array_resultados;
(...)
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic -- create and push a new view controller
if (indexPath.row == 2)
{
if(dvc != nil)
[dvc dealloc];
NSString *ffs = [[array_resultados objectAtIndex:indexPath.row] TituloFilme];
dvc = [[DetalhesViewController alloc] initWithNibName:@"DetailedView" bundle:[NSBundle mainBundle]];
**resultadosControllerCell.array_resultados = [self array_resultados];**
*"Request for member 'array_resultados' in something not a structure or union"*
//Push the view controller to the top of the stack.
[self.navigationController pushViewController:dvc animated:YES];
}
}
</code></pre>
<p>And here's the other class i want to send the array into:</p>
<h2>DetalhesViewController.h:</h2>
<pre><code>#import <UIKit/UIKit.h>
#import "Filme.h"
#import "Festival.h"
#import "Top10Discos.h"
#import "Peca.h"
@interface DetalhesViewController : UIViewController
{
// Navegacao
NSArray *array_resultados;
}
@property (nonatomic, retain) NSArray *array_resultados;
@end
</code></pre>
<p>I'm not sure if any of you would to see the .m file for this class; in that case, just ask.</p>
<p>Thanks in advance,
Hal</p>
<p>PS: tried with other variables (other types too), cleansed/rebuilt, recreated xib file, you name it... i'm outta tricks :(</p>

383,104 | <p>When testing in any language, how does everybody <strong>phrase their assertion messages</strong>?</p>
<p>I see three obvious ways:</p>
<pre><code># assume failure
assert (4-2) == 2, "Subtracting 2 from 4 doesn't equal 2"
# describe success
assert (4-2) == 2, "Subtracting 2 from 4 should equal 2"
# be vauge with failure
assert (4-2) == 2, "Subtracting 2 from 4 is broken"
</code></pre>
<p>This is obviously a simple example, but you get the idea. What is the standard practice? What do you do? Why?</p>

383,194 | <p>A lot of times when reading about web developping on the internet I hear that you should split up your javascript and css files into multiple files.<br>
Like split up your css files in a:</p>
<ul>
<li>clear.css</li>
<li>base.css</li>
<li>page_specific.css</li>
</ul>
<p>Or that you should even split those up into files containing positioning, colour and typography information.</p>
<p>But isn't it true that a browser is only allowed to make two simultaneous http requests? Splitting the files up into that many would create a whole load of http requests. Isn't it better to just split them into two files, a page specific and and a base/clear css file? and then send them with loads of cache headers? </p>
<p>I understand that splitting up the files is easier for development but shouldn't speed be more important?</p>

As a second part of my question: if there are UTF-8 encoded strings being sent back as a response, I guess I would then need another function to get it back into a Delphi string format. I understand the limitations of such Unicode support in this way.</p>

<blockquote>
<p>Note: ECMAScript defines an internal [[prototype]] property of the internal Object type. This property is not directly accessible with scripts, but it is the chain of objects referred to with the internal [[prototype]] property that is used in property accessor resolution; the object's prototype chain. A public prototype property exists to allow the assignment, definition and manipulation of prototypes in association with the internal [[prototype]] property. <strong>The details of the relationship between to two are described in ECMA 262 (3rd edition) and are beyond the scope of this discussion.</strong></p>
</blockquote>
<p>What are the details of the relationship between the two? I've browsed through ECMA 262 and all I've read there is stuff like:</p>
<blockquote>
<p>The constructor’s associated prototype can be referenced by the program expression constructor.prototype,</p>
<p>Native ECMAScript objects have an internal property called [[Prototype]]. The value of this property is either null or an object and is used for implementing inheritance.</p>
<p>Every built-in function and every built-in constructor has the Function prototype object, which is the initial value of the expression Function.prototype</p>
<p>Every built-in prototype object has the Object prototype object, which is the initial value of the expression
Object.prototype (15.3.2.1), as the value of its internal [[Prototype]] property, except the Object
prototype object itself.</p>
</blockquote>
<p>From this all I gather is that the [[Prototype]] property is equivalent to the <code>prototype</code> property for pretty much any object. Am I mistaken?</p>

383,211 | <p>I'm spending a bit of time with Erlang, and I'm wanting to apply TDD to code I'm writing.</p>
<p>While <a href="http://www.erlang.org/doc/apps/eunit/chapter.html" rel="noreferrer">EUnit</a> in the standard lib provides a nice traditional unit testing framework for testing regular style code, there doesn't seem to be anything to help specifically with testing concurrent code, which is used a LOT in Erlang.</p>
<p>Note that we're talking Erlang here, which uses message passing (as opposed to shared state) for communication between concurrent processes, so techniques for unit testing concurrent code in shared state languages may not be applicable.</p>
<p>Anyone found a good way to test concurrent code in Erlang?</p>

<pre><code>/// <exception cref="IndexOutOfRangeException">if index is less than 0

public T this[int index] { get { return myArray[index]; } }

<p>I am thinking about the case when this class would be used from a .NET language that indexes arrays starting from 1. I don't know much about the topic, but is the second version better than the first by any means?</p>

383,307 | <p>A simple question</p>
<p>Consider this piece of code in C#</p>
<pre><code>String a;
String b;
String c;
1. a =
2. b =
3. //Comment
4. c = "a String";
</code></pre>
<p>During compilation, it was fine, but i hit an error when I run my application. From my logs, the error occur at the above.</p>
<p>Question: </p>
<p>Is the error caused by the comment in line 3? </p>
<p>The error is "Object reference not set to an instance of an object" </p>
<p>I'm guessing the compiler treats the above code as 1 statement.</p>
<p>This code resides in the code behind of an aspx page. (aspx.cs)</p>
<p>//Backstory//</p>
<p>The aspx was tested in the test servers and was file. However after we deployed the page to the production server, there is an error at pageload(), the line where the error occur is at line 1 of my code example above.</p>
<p>It is just my suspicion that the error is caused by the comment.</p>
<p>Am I right?</p>

383,347 | <p>Let's say I've got an object <code>Customer</code> with a couple properties (<code>ID</code>, <code>FirstName</code>, <code>LastName</code>). I've got the default constructor <code>Customer()</code>, but then I've also got a <code>Customer(DataRow dr)</code>, since I load this object from a database and that's a simple way to do it.</p>
<p>I frequently come to a point where I want to set up another constructor, <code>Customer(int ID)</code>, for times when I want to load a <code>Customer</code> but I haven't made the trip to the database yet. The simplest way to me seems to be like so:</p>
<pre><code>Customer(int ID)
{
DataTable dt = DataAccess.GetCustomer(ID);
if (dt.Rows.Count > 0)
{
// pass control to the DataRow constructor at this point?
}
else
{
// pass control to the default constructor at this point?
}
}
</code></pre>
<p>It makes sense to reuse the code that's already in the DataRow constructor, but I can't figure out a way to call that and return what it gives me. Through Googling, I've found information about constructor overloading with the <code>: this()</code> syntax, but all those examples seem backwards or incompatible with what I'm trying to do. </p>
<p>So there's a gap in my understanding of constructors, but I can't seem to sort it out. What am I missing?</p>

// check
int firstLaunch = [[NSUserDefaults standardUserDefaults] integerForKey:@"mySetting"];
// set
[[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"mySetting"];
</code></pre>
<p>Now for development purposes, I'd like to be able to remove the saved data and go back to the defaults, without having to remove the app and re-install it each single time. Is there a quick way to do that? I thought resetStandardUserDefaults would do the job, but it doesn't.</p>

383,389 | <p>I recently wanted to get a decend IDE for my PHP side-projecs, and by searching SO found Eclipse+PDT. Although it's not quite at the level of Visual Studio yet, it's pretty nice and better than Notepad++ for this purpose. I can even debug somewhat, although it's pretty glitchy.</p>
<p>But there is one thing that is bugging me. It seems to have some kind of weird performance issue, whereupon it it uses lots of CPU about once a minute or so. By itself this is not noticeable, but if you do something else at the same time (like watch a movie, or play Quake 3), it produces an annoying hicup now and then.</p>
<p>Granted, my computer is not state-of-the-art (Sempron 2200+ with 1GB of RAM), but then it's certainly more than enough for all of this.</p>
<p>Another performance question is that I'm used to Visual Studio where IntelliSense pops up as soon as you type a compatible symbol. Here you have to wait for a moment. Is there any way to make it open up instantly?</p>
<p>P.S. Perhaps there's an even better <strong>freeware</strong> IDE for PHP?</p>
<p><b>Added:</b> It was suggested by Stefan Schmidt to change Auto-Activation speed. It seems that there is a bug with this. The smaller I set it, the more it fails to open at all. For example, when it's 200, it opens mostly all the time when there is something to open. At 10 it doesn't open (at least) for static class members. What gives?</p>

383,402 | <p>In <a href="https://stackoverflow.com/questions/377716/javascript-automatic-gettersetters-john-resig-book">another question</a>, a user pointed out that the <code>new</code> keyword was dangerous to use and proposed a solution to object creation that did not use <code>new</code>. I didn't believe that was true, mostly because I've used <a href="https://en.wikipedia.org/wiki/Prototype_JavaScript_Framework" rel="nofollow noreferrer">Prototype</a>, <a href="https://en.wikipedia.org/wiki/Prototype_JavaScript_Framework" rel="nofollow noreferrer">Script.aculo.us</a> and other excellent JavaScript libraries, and everyone of them used the <code>new</code> keyword.</p>
<p>In spite of that, yesterday I was watching Douglas Crockford's talk at YUI theater and he said the exactly same thing, that he didn't use the <code>new</code> keyword anymore in his code (<a href="http://www.youtube.com/watch?v=ya4UHuXNygM&t=50m23s" rel="nofollow noreferrer">Crockford on JavaScript - Act III: Function the Ultimate - 50:23 minutes</a>).</p>
<p>Is it 'bad' to use the <code>new</code> keyword? What are the advantages and disadvantages of using it?</p>

383,405 | <p>I'm working on a small GreaseMonkey script where I would like to embed a jQuery plugin (Markitup) so that the script is fully self contained (images + js) except for jQuery which is served from google.</p>
<p>I found the site <a href="http://www.greywyvern.com/code/php/binary2base64" rel="noreferrer">http://www.greywyvern.com/code/php/binary2base64</a> which says that you can embed javascript with the href if you base64 encode the script, much like serving images as basse64 from CSS.</p>
<pre><code><script type="text/javascript" href="data:text/javascript;base64,dmFyIHNjT2JqMSA9IG5ldyBzY3Jv..."></script>
</code></pre>
<p>So i tried that but couldn't get it to work at all, using Firefox 3.0.5 on OS X.</p>
<p>I put together a small test page to isolate the problem but couldn't get it to work at that page either.</p>
<pre><code><!DOCTYPE HTML>
<html>
<head>
<title>Title</title>
<meta charset="utf-8">
</head>
<body>
<script href="data:text/javascript;base64,YWxlcnQoJ2FzYWRhc2QnKTsK"></script>
<script>alert('a');</script>
</body>
</html>
</code></pre>
<p>The base64 string (YWxlcnQoJ2FzYWRhc2QnKTsK) says <code>alert('asadasd');</code> so I'm supposed to get two alerts but the only one I see is the second one where the alert is located as text inside the script tag.</p>
<p>Am I doing something wrong or why isn't this working, any ideas?</p>

383,416 | <p>If I am using <code>ReaderWriterLockSlim</code> to acquire read/write locks, do I need to make my variables <code>volatile</code> or use <code>Interlocked.Increment</code>?</p>
<p>For example, would the code in the <code>Add</code> method below work fine, or does it need enhancement?</p>
<pre><code>public class AppendableList<T> { // semi-immutable; supports appending only
private T[] data = new T[16];
private ReaderWriterLockSlim rwLock = new ReaderWriterLockSlim();
public int Count { get; private set; }
public T this[int index] {
get {
rwLock.EnterReadLock();
try { return data[index]; } finally { rwLock.ExitReadLock(); }
}
}
public void Add(T item) {
rwLock.EnterUpgradeableReadLock();
try {
if (Count == data.Length)
reAllocateArray(); // upgrades to write lock
data[Count++] = item; // do I need to use Interlocked here?
} finally { rwLock.ExitUpgradeableReadLock(); }
}
}
</code></pre>
<p><strong>EDIT:</strong> I'm trying to write a light-weight, fast and simple list that allows multiple threads to access its data concurrently (sort of producer-consumer buffer). I have edited the code above removing the simplifications I used before, so the issue should be clearer now. It seems to me that this code is thread-safe, but I am not sure whether all threads will see the updated value of <code>Count</code> right after exiting the upgradeable lock.</p>
<p><strong>EDIT 2</strong>: The "Write" lock here is used to indicate writing to the <em>array reference</em>, not the array elements. I'm assuming this is sufficient (since the data itself is immutable). I guess that I need to use Interlocked when incrementing <code>Count</code>. Is that true?</p>

383,444 | <p>Is it possible to do a google map lookup using the google maps API from a UK postcode? I know you can search by UK postcode on their website, but this converts to lat / long. I don't have access to the PAF database to be able to convert to long / lat.</p>
<p>An example:</p>
<p>Users have an item to sell. One of the details of that item is a postcode, where the user / item is located. When the items are displayed on the front end of the website, there needs to be a google map of the items location generated using the postcode.</p>
<p>If this is possible, how do I do it?</p>

383,480 | <p>Have created a c++ implementation of the Hough transform for detecting lines in images. Found lines are represented using rho, theta, as described on wikipedia:</p>
<blockquote>
<p>"The parameter r represents the distance between the line and the origin, while θ is the angle of the vector from the origin to this closest point "</p>
</blockquote>
<p>How can i find the intersection point in x, y space for two lines described using r, θ?</p>
<p>For reference here are my current functions for converting in and out of hough space:</p>
<pre><code>//get 'r' (length of a line from pole (corner, 0,0, distance from center) perpendicular to a line intersecting point x,y at a given angle) given the point and the angle (in radians)
inline float point2Hough(int x, int y, float theta) {
return((((float)x)*cosf(theta))+((float)y)*sinf(theta));
}
//get point y for a line at angle theta with a distance from the pole of r intersecting x? bad explanation! >_<
inline float hough2Point(int x, int r, float theta) {
float y;
if(theta!=0) {
y=(-cosf(theta)/sinf(theta))*x+((float)r/sinf(theta));
} else {
y=(float)r; //wth theta may == 0?!
}
return(y);
}
</code></pre>
<p>sorry in advance if this is something obvious..</p>

383,510 | <p>We have a large Java application that run as applet or Java Web Start. And it grow more and more. Typical a user need only a small part of the classes. Because Java does not know which class can it found in which jar file that it load all jar files until it find the class. If it will load a class that not exist (for example a resource bundle) then it load all jar files. This reduce the start time on a small bandwidth very large.</p>
<p>Is there a small framework with which we can load the plugins only if needed? Or better if needed and on background?</p>
<p>Of course the framework should not delay the start time self with it large size.</p>
<p>I think it should use a URLClassLoader for downloading.</p>

383,550 | <p>im just starting to learn flex and im trying to understand how Flex does remoting? From what i have read it looks like Flex provides a LifeCycle data services war which sits on your server and intercepts your remote calls , is this close?</p>
<p>Im concerned that if i use this option that 1. Ill have to add an extra war to my server - the lifecycle data service war and 2. That i will have to pay for a license for each instance i use on each cpu.</p>
<p>Is there an easier [free] option out there which i can use to call my remote java objects from within my flex mxml?</p>
