Strange Stack Overflow Error in Sudoko Backtracker
(Disclaimer: There are maybe 20 different versions of this question on SO,
but a reading through most of them still hasn't solved my issue)
Hello all, (relatively) beginner programmer here. So I've been trying to
build a Sudoku backtracker that will fill in an incomplete puzzle. It
seems to works perfectly well even when 1-3 rows are completely empty
(i.e. filled in with 0's), but when more boxes start emptying
(specifically around the 7-8 column in the fourth row, where I stopped
writing in numbers) I get a Stack Overflow Error. Here's the code:
import java.util.ArrayList;
import java.util.HashSet;
public class Sudoku
{
public static int[][] puzzle = new int[9][9];
public static int filledIn = 0;
public static ArrayList<Integer> blankBoxes = new ArrayList<Integer>();
public static int currentIndex = 0;
public static int runs = 0;
/**
* Main method.
*/
public static void main(String args[])
{
//Manual input of the numbers
int[] completedNumbers = {0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0,3,4,
8,9,1,2,3,4,5,6,7,
3,4,5,6,7,8,9,1,2,
6,7,8,9,1,2,3,4,5,
9,1,2,3,4,5,6,7,8};
//Adds the numbers manually to the puzzle array
ArrayList<Integer> completeArray = new ArrayList<>();
for(Integer number : completedNumbers) {
completeArray.add(number);
}
int counter = 0;
for(int i = 0; i < 9; i++) {
for(int j = 0; j < 9; j++) {
puzzle[i][j] = completeArray.get(counter);
counter++;
}
}
//Adds all the blank boxes to an ArrayList.
//The index is stored as 10*i + j, which can be retrieved
// via modulo and integer division.

for(int i = 0; i < 9; i++) {
for(int j = 0; j < 9; j++) {
if(puzzle[i][j] == 0) {
blankBoxes.add(10*i + j);
containsEmpty = true;
}
}
}
filler(blankBoxes.get(currentIndex));
}
/**

*/
public static boolean checkDupl(int[] testArray) {
for(int i = 0; i < 8; i++) {

for(int j = i + 1; j < 9; j++) {

* 0, and the index beforehand is rechecked.
*/
public static void filler(int indexOfBlank) {
//If the current index is equal to the size of blankBoxes, meaning
that we
//went through every index of blankBoxes, meaning the puzzle is
full and correct.
runs++;
if(currentIndex == blankBoxes.size()) {

//Adds one to the value of that box.
puzzle[row][column] = (puzzle[row][column] + 1);
//Just used as a breakpoint for a debugger.

}

}

public static boolean checkSingleColumn(int column) {
int[] singleColumn = new int[9];

singleColumn[i] = puzzle[i][column];
}
return checkDupl(singleColumn);
}
public static boolean checkSingleBox(int row, int column) {
//Makes row and column be the first row and the first column of
the box in which
//this specific cell appears. So, for example, the box at
puzzle[3][7] will iterate
//through a box from rows 3-6 and columns 6-9 (exclusive).
row = (row / 3) * 3;
column = (column / 3) * 3;
//Iterates through the box
int[] newBox = new int[9];
int counter = 0;
for(int i = row; i < row + 3; i++) {
for(int j = row; j < row + 3; j++) {
newBox[counter] = puzzle[i][j];
counter++;
}
}
return checkDupl(newBox);
}
}
Why am I calling it a weird error? A few reasons:
The box that the error occurs on changes randomly (give or take a box).
The actual line of code that the error occurs on changes randomly (it
seems to always happen in the filler method, but that's probably just
because that's the biggest one.
Different compilers have different errors in different boxes (probably
related to 1)
What I assume is that I just wrote inefficient code, so though it's not an
actual infinite recursion, it's bad enough to call a Stack Overflow Error.
But if anyone that sees a glaring issue, I'd love to hear it. Thanks!

importantly, I read somewhere that apple will complain about warnings in

1) Will Apple complain about warnings in your code?
2) Am I handling deprecated methods correctly?
3) Is there way to turn deprecated method method warnings off?

How do you add mysql-connector-java-5.1.26 to Eclipse Android Developer Tools
How do you add mysql-connector-java-5.1.26 to Eclipse Android Developer Tools
I want the following line of code to work in Eclipse Java but apparently I
need to import/add mysql-connector-java-5.1.26 to my eclipse android
project so I can send a mySQL query via an android device.
Class.forName("com.mysql.jdbc.Driver");
How can I add the mySQL library to a current project? I've seen other
tutorials about doing this here at stack overflow but they've been kind of
unspecific and just say "just ADD it to your current project" but that's
where I'm stumped.
Most tutorials online just tell you how to start a new project from
scratch, but I'm working with an android application.
Do I go to File>Import? and then select the .zip with the mySQL files? Or
do I select the folder or something? I'm doing this on a Mac.
Thanks.

Backbone: Scroll event not firing after back button is pressed
Backbone: Scroll event not firing after back button is pressed
As you can see here, when you click on an image and then click back,
Chrome doesn't let you scroll down anymore. I'm using the following
function to change the primary view of my Backbone application:
changeView: function(view, options) {
if (this.contentView) {
this.contentView.undelegateEvents();
this.contentView.stopListening();
this.contentView = null;
}
this.contentView = view;
if (!options || (options && !options.noScroll)) {
$(document).scrollTop(0);
}
this.contentView.render();
},
This function is called every time the route changes. As you can see, I'm
resetting the scroll position every time the primary view changes (so that
the user doesn't land on the middle of a view after scrolling down on the
previous view). However, when the user presses the back button, the scroll
event isn't firing at all if you try to scroll down. If you try to scroll
up, however, then the scroll positions seems to get reset to a position
further down the page, after which scrolling works normally.
Any ideas on what the cause might be?

Efficient use of sockets in c#
Efficient use of sockets in c#
I am using Sockets in C#.
I am using this to connect:
client = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
client.Connect(remoteEP);
I send a message using client.send...
I receive a message using client.receive...
I have read to maximise the performance of using sockets I should use
Ayscn Sockets.
Is this true and is there an optimised buffer number to use? e.g
buffer[256] (etc).
Also, on the Server side I assign a thread to an incoming client request.
Once the work is completed i close the socket. I have found this a good
way to manage clients but I have also found suggestions that this is not
the best way to go. Really just need advice on the best way to go and why.
thanks..

Prevent inclusion of mean in boxplot legend
Prevent inclusion of mean in boxplot legend
In ggplot2 boxplot with added mean, is there a way to prevent the mean
from being included with the legend? I must use a large point size and
find its inclusion in the legend distracting. The conceptually closest
problem I could find, for removing the slash from the legend of outlined
bar charts, is at
http://www.cookbook-r.com/Graphs/Legends_%28ggplot2%29/#modifying-the-legend-box
That solution uses geom_bar twice to overlay one plot on another, the
second, outlined bar chart, without a legend. But is there a solution for
preventing the mean from appearing in the boxplot legend?
ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) +
geom_boxplot() +
stat_summary(fun.y=mean, colour="darkred", geom="point", shape=18, size=3) +
# idea from above website

PHP + Mysql and memcache or phpsessions
PHP + Mysql and memcache or phpsessions
I currently manage a game that handles around 8K daily users, the current
server setup is
VPS: 16GB+8cores+ 160GBSSD.
Handles 8K daily users that are generating 600K daily direct calls to the
mysql DB;
The situation is: The game is growing, and server response is slowing down.
So! I'm looking for options to avoiding having an incredibly slow server,
and saw Memcache as a viable solution, and studying it I came up with 2
questions, which are:
Is it safe to store ONE Key value per user, that contains all user data,
perhaps as a concatenated string that would be around 100 characters long,
and then update the DB every once in a while? ->that would mean having
thousands of keys at the same time.
The idea is not to replace mysql, just to aid it in the users session and
be able to update the DB every so often, for this situation would Sessions
or Memcache be the right way to go?
thank you very much :)

says it will mess up the dump. If 64-bit taskmgr does mess up the memory
dump of 32-bit processes, is there a way to convert the already-done
memory dump so that it will be properly analyzed?
Also, if you have full memory dump available, can a person re-create
processes and programs running before crash occurred?

http://blogs.msdn.com/b/tess/archive/2010/09/29/capturing-memory-dumps-for-32-bit-processes-on-an-x64-machine.aspx
I used 64-bit Windows 7's normal task manager (taskmgr) to dump the memory
of chrome processes, which are 32-bit, but then I read an article that
says it will mess up the dump. If 64-bit taskmgr does mess up the memory
dump of 32-bit processes, is there a way to convert the already-done
memory dump so that it will be properly analyzed?
Also, if you have full memory dump available, can a person re-create
processes and programs running before crash occurred?

iOS Static library for unity with App switching issue Facebook integration
iOS Static library for unity with App switching issue Facebook integration
These days i am writing a iOS static library for unity games facebook
integration. Static library functionality is done and it works perfect.
One issue i am facing is dont have any appdelegate inside my static
library code so i cant add
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
NSLog(@"openURL");
return [FBSession.activeSession handleOpenURL:url];
}
Anywhere. This method needed to control app switching when app switch to
get read or publish permissions. I created a demo project and added this
method to the app delegate of demo project and it works Perfect but if i
dont add this method to Appdelegate of demo project app switching does not
happen. I dont want the plugin user to add this method manually after
getting output from unity.
Is there any way to figure it out. So that app switching works perfect. Do
i need add an appdelegate to static library classes or something else.

What's wrong with the facebook login?
Whenever I log-in to Facebook I always go to this URL

log-in it would take me directly to my main news feed. This started
happening about 2 days ago.

Android - Coding onActivityResult for embedded startActivityresult in custom CursorAdapter
Android - Coding onActivityResult for embedded startActivityresult in
custom CursorAdapter
Within my project I have an activity with a multi-column ListView. This
ListView draws its data from a custom CursorAdapter that I've implemented
in a separate java module. I have listeners on a couple of the views
within the ListView's rows, and these are implemented within the
CursorAdapter. One of the listeners needs to edit the view content that
called it and save the data back to the underlying database.
Based on advice received here I've managed to code the
startActivityForResult. However, I can't find how or where to code the
onActivityResult routine in order to process the response from the dialog
activity. Has anyone any advice?
public class CustomCursorAdapter extends CursorAdapter {
private static final String TAG = CustomCursorAdapter.class.getSimpleName();
private static final int EDIT_TIME_REQUEST_CODE = 11;

intentTimeEdit.putExtra("Time", strTime);
// Set up intent to pass to dialog

if I run it locally on a macbook it works, I use node-phantom-simple
without socket.io and cluster support. I can't change the permissions on
the phantomjs binary, they stay always 700, and heroku support told me,
that i'm responsible for the permissions on the files via buildpack.
Any suggestions?

How to "unzip" then slice and find max for elements in a list of lists in Python
How to "unzip" then slice and find max for elements in a list of lists in
Python
I have a list of lists and need to find a way to find the max of the
numerical portion of element [0] of each list. I know it'll involve
slicing and finding max and think it'll involve the zip(*L) function but
don't really know how to get there. For example, what I have is a list of
lists that looks like this:
L = [['ALU-001', 'Aluminum', 50], ['LVM-002', 'Livermorium', 20],
['ZIN-003', 'Zinc', 30]]
and need to find the largest numerical portion (ex. 001) of the first
elements.

Android keyboard and remapping the CTRL key
Android keyboard and remapping the CTRL key
I have an Samsung Galaxy 10.1 running Android version 4.1.2. I am using
ssh to remotely connect to my main machine which runs Ubuntu 12.04 LTS.
Once I am connected I do all my work in emacs 24.3. I also have a
bluetooth keyboard.
My question is about remapping the Caps-Lock key to function as the Ctrl
key. I do this with my main machine by changing a setting in the terminal
options. I checked the options in juiceSSH and there appears to be no
equivalent. Perhaps there is a general way to do this with Android or the
Bluetooth Keyboard.
How can I remap the Caps-Lock character to function as the Ctrl character?
If you need more information let me know. Thanks in advance!

Ajax Posts but does not call Django View
Ajax Posts but does not call Django View
The Problem
After posting to my django view, the code seems to just stop halfway through.
I have an ajax post to a Django view that is hard coded to render a
specific response (see below). When I post to that view it should always
return that response, but for some reason the view out puts all of the
print statements, but not the query or the render. I know I'm being
redirected by my sever log (shown below).
Any idea what could be causing this behavior?

Associate specific SLF4J logger with Jetty embedded
Associate specific SLF4J logger with Jetty embedded
I'm trying to assign a specific SLF4J logger instance to my Jetty embedded
server using the following lines of code:
Logger myLogger = LoggerFactory.getLogger("Web Server");
Log.setLog((org.eclipse.jetty.util.log.Logger) myLogger)
where myLogger is an instance of org.slf4j.Logger. This returns a
ClassCastException since
org.slf4j.impl.Log4jLoggerAdapter cannot be cast to
org.eclipse.jetty.util.log.Logger`
How then can I go about this process?

Progromatically hide overflow button in Android
Progromatically hide overflow button in Android
I have a searchView widget in the action bar. I've seen a few guides to
hiding particular action bar buttons progromatically. However I want to
keep one other button there but hide the overflow button if I could to
conserve action bar space, and the overflow button isn't covered in any of
these other questions.
It would have to come back after the searchview is closed as well. I hope
to do this with a searchview listener.

How do I correctly proxy https traffic?
How do I correctly proxy https traffic?
I'm trying to set up a proxy server that can handle both http and https
traffic without prompting the browser about certificates (just like
tunlr.net).
So far I've tried to use Squid and Nginx.
While handling regular http traffic is a walk in the park, https is
proving very difficult.
Can anybody point me in the right direction?

im creating a control panel, and the control panel needs to know who's
logged in and if he is an admin, on just about ever page of this project.
right now to get this to work i have this in my header of every page:
$user = $this->ion_auth->user()->row();
$fname = $user->first_name;
$lname = $user->last_name;
$email = $user->email;
$uid = $user->id;
$avatar = $user->avatar;
however, im now thinking i should be able to do this in the model ya?
maybe using a helper or library? if im thinking correctly could someone
give me a rough step by step on how to do that? Ive never created a helper
or library in codeigniter.
I asked a similar question a while back but i dont think im doing it
correctly.

How to disable an eventHandler in pyqt?
How to disable an eventHandler in pyqt?
I need to disable the textChanged()-Signal of a QTextBrowser if I need to.
I want to do this because of this: Typing in a qtextbrowser, then through
the connection of textChanged() in realtime formating the content, and
re-setting it into the qtextbrowser triggers textChanged() and this again
the realtime formatting ... infinite loop. So I need to disable that the
formatting triggers textChanged().
How do I do this in pyqt4?

How do I create a list of user inputs?
How do I create a list of user inputs?
I am coding in Java and I have to create a program that accepts user
input, which I have done. But I am confused as to what statement I can use
to list those integer input by the user.
This is what I have so far:
//Biker's Journey Program
import java.util.Scanner;
public class lab2
{
public static void main( String[] args )
{
Scanner input = new Scanner( System.in);
int w;
int x;
int y;
int z;
int result;
System.out.print("Please enter the first day's traveled miles: ");
w = input.nextInt();
System.out.print("Please enter the second day's traveled miles: ");
x = input.nextInt();
System.out.print("Please enter the third day's traveled miles: ");
y = input.nextInt();
System.out.print("Please enter the last day's traveled miles: ");
z = input.nextInt();
System.out.print("The number of miles traveled was: ");
System.out.println()
result = (w + x + y + z) / 4;
System.out.printf("The average miles per day traveled is %d\n", result);
}
}
And this segment of code does the computing, I just can not figure out how
to get the integers listed like this this picture:

Calling a click event or JQuery function from the code behind VB.NET
Calling a click event or JQuery function from the code behind VB.NET
I have a JQuery (v1.8) which handles the code after clicking a hyperlink.
I would like to call that click or do anything else (as the clicking of
the link would) to enforce the JQuery to run from the code behind. Any
ideas?
JQuery code:
<script type="text/javascript">
jQuery(document).ready(function (){
jQuery('#lnkShowModule').toggle(
function (){
jQuery(this).html('Hide the Module');
jQuery('.hide-element').toggle();
},
function (){
jQuery(this).html('Show the Hidden Module');
jQuery('.hide-element').toggle();
}
);
});
and this is my link on the ascx control:
<a id="lnkShowModule" href="#"> show the hidden module</a>

Connect 4 game javascript diagonal checking from Southeast to Northwest
Connect 4 game javascript diagonal checking from Southeast to Northwest
This is related to the post "algorithm connect four javascript" answered
by user:462803 Koviko. I just used the codes of Koviko in my connect 4
javascript. But I encountered issue.
This is the codes of Koviko:
function isVictory(placedX, placedY) {
var i, j, x, y, maxX, maxY, steps, count = 0,
directions = [
{ x: 0, y: 1 }, // North-South
{ x: 1, y: 0 }, // East-West
{ x: 1, y: 1 }, // Northeast-Southwest
{ x: 1, y: -1 } // Southeast-Northwest
];
// Check all directions
outerloop:
for (i = 0; i < directions.length; i++, count = 0) {
// Set up bounds to go 3 pieces forward and backward
x = Math.min(Math.max(placedX - (3 * directions[i].x), 0),
circle.length );
y = Math.min(Math.max(placedY - (3 * directions[i].y), 0),
circle[0].length );
maxX = Math.max(Math.min(placedX + (3 * directions[i].x),
circle.length ), 0);
maxY = Math.max(Math.min(placedY + (3 * directions[i].y),
circle[0].length ), 0);
steps = Math.max(Math.abs(maxX - x), Math.abs(maxY - y));
for (j = 0; j < steps; j++, x += directions[i].x, y += directions[i].y) {
if (circle[x][y] == circle[placedX][placedY]) {
// Increase count
if (++count >= 4) {
return true;
break outerloop;
}
} else {
// Reset count
count = 0;
}
}
}
//return count >= 4;
}
I slightly edit the code. But that is the final code that is working with
my connect four game. The only problem is the Southeast to Northwest
traverse is not working, and it will only win this coordinates
Southeast-Northwest 6,0 5,1 4,2 3,3.
Though I have completed this in a hardcode way but I just want to finish
this game that using javascript math object for better runtime. Here is
the demo: http://jsfiddle.net/iahboy/Cwp8x/.
Thank you so much. Hope someone will help me.

I am running a Centos machine in Amazon cloud. Suddenly, I can't ssh into

When I run it from the command line sudo service sshd start I get an error
that Starting sshd: /etc/ssh/sshd_config: Permission denied. I tried to
set sshd_config permissions to either 644 or 600 - but I get the same

And it is not the limitation of the shell itself: I can start httpd
without any problems.

python: cooperative supercall of __getattr__
python: cooperative supercall of __getattr__
I'm working with somethign similar to this code:
class BaseClass(object):
def __getattr__(self, attr):
return lambda:'1'
class SubClass(BaseClass):
suffix = '2'
def foo(self):
return super(SubClass, self).foo() + self.suffix
class SubClass2(SubClass):
suffix = '3'
def foo(self):
return super(SubClass2, self).foo() + self.suffix
o = SubClass2()
print o.foo()
I'd expect to see output of '123', but I instead I get an error
AttributeError: 'super' object has no attribute 'foo'. Python isn't even
attempting to use the base class's __getattr__.
Without modifying the base class, and keeping the two super calls similar,
I'm not able to get the output I want. Is there any cooperative supercall
pattern that will work for me here?
I understand that super() overrides getattr in some way to do what it
needs to do, but I'm asking if there's any reasonable workaround that
allows a subclass's __getattr__ to be called when appropriate.

Dealing with CORS and Cookie domain across subdomains
Dealing with CORS and Cookie domain across subdomains
I'm having difficulty reconciling some conflicting information from
StackOverflow and other sources regarding the use of calls across
sub-domains. Consider these two independent sites that share a common
domain:
site #1: www.myDomain.com
site #2: sub.myDomain.com
Requirements:
(1) Site #1 must be able to execute an AJAX call to site #2 by way of
sub.myDomain.com/handler.ashx.
(2) Site #1 and Site #2 must be able to read each other's cookies.
These requirements lead me to the following questions:
(1) Does the handler code located at sub.myDomain.com/handler.ashx need to
alter its response headers to allow CORS? I know that I can write a call
like this:
resp.Headers.Add("Access-Control-Allow-Origin","*");
…but from what I read, this will expose the handler to all domains. I just
want to limit the calls to those originating from *.myDomain.com. What if
I don't include the CORS header at all? What's the default behavior?
(2) Do Site #1 and/or Site #2 need to tweak the Domain property of
HttpCookie in order for the two sites to read each other's cookies?
What if I don't touch the Domain properties at all? What's the default
behavior? Some forum responses suggest that cookie scope will be limited
to the subdomain, while others suggest the entire domain is in scope
(which is what I want) in which case no action would be required on my
part.
Thanks.

Front end development: where to start?
Front end development: where to start?
I'm very sorry if that question has been asked already, couldn't find
anything closely related though.
By now I've pretty much learned HTML/HTML5, CSS/3, learned using JQuery
(not saying there's nowhere to improve, obviously there is). I really want
to start learning front-end dev (client MVC, etc). I've started learning
backbone.js, but it turns out i'm having difficulties learning it. Am I
missing something? I've read "JS: Good Parts" and Javascript Garden is
basically my go-to source yet I still get confused.
I'd appreciate any recommendations as to what I should learn/practice
first, thanks :)

Oh-My-Zsh rails3 plugin aliases fail in rails 4
Oh-My-Zsh rails3 plugin aliases fail in rails 4
My rails version is 4.0.0. I'm using Oh-My-Zsh and I like it for it's hugh
plugin repository and intelligence. However, I've activated the rails3
plugin which is supposed to give me aliases mentioned in this oh-my-zsh
wiki. I have tried several of them like rg, rgbm, rgbm, rs but all of them
shows this error:
ruby: No such file or directory -- script/rails (LoadError)
Is this an incompatibility error of rails 4 environment and rails3 plugin
of oh-my-zsh? Is there a way to fix it? Thanks in advance.

Sticky Footer Creating Infinite Scrolling
Sticky Footer Creating Infinite Scrolling
Just what the title says! Feel free to have a look here at this WordPress
(Genesis) site we created a while back. The sticky footer plugin I created
(with some generous assistance from all you fine folk here) is working
well, but it keeps creating this weird infini-scroll effect.
Any idea what's happening here? I'm stumped, though I suspect there's
something in the jQuery I'm not knowledgeable enough about to fix.
Thanks for any assistance you can offer!

ddf standard xml format returns no records
I am using the code below to query the CREA DDF/RETS to retrieve listings

If I do not specify the format, PHRETS defaults to Compact-Decoded format

PEAR Install out of memory
PEAR Install out of memory
I am trying to install PEAR into WAMP on Windows Server 2008.
When I do:
V:\wamp\bin\php\php5.4.12>php go-pear.phar
I get:
PHP Fatal error: Allowed memory size of 262144 bytes exhausted (tried to
alloca
te 91 bytes) in Unknown on line 0
Fatal error: Allowed memory size of 262144 bytes exhausted (tried to
allocate 91
bytes) in Unknown on line 0
I have tried to solve the error via Googling but all I get is people
saying to increase PHP memory limit. This is not the problem.
I have two php.ini files, one in Apache one in PHP. I don't know why there
is two but regardless I have set the memory_limit in both to 4096MB, and I
still get the error.
How can this be fixed so I can install PEAR?

Sitecore ECM how to track the same user's activities in different target audiences
Sitecore ECM how to track the same user's activities in different target
audiences
We are using Sitecore 6.5, and the Email Campaign Manager 1.3.3 rev.130212
is installed.
Currently, when i add a Sitecore user, for example 'UserA' to multiple
target audiences, lets say 'TargetAudience_A' and 'TargeAudience_B', after
I send out these two target audiences, 'UserA' clicks the link in the
email which comes from 'TargetAudience_A', then the link will bring user
to the site, user visits several pages, Sitecore Analytics will be able to
track 'UserA' VisitPageCount and Value, and creates the corresponding
campaign of 'TargetAudience_A' with that data.
When the user open the email send from 'TargetAudience_B' and clicks the
link, visits the site, NO campaign is created for 'TargetAudience_B' in
the database, I can see all the data should use to create a new campaign
for 'TargeAudience_B' is used to update campaign of 'TargetAudience_A'.
All the link in the sent email has been modified by Sitecore, the
corresponding campaign id is added, which make the link looks like
this:'httP:xx.domain.com/?ec_camp=xxxx&ec_as=xxxx'.
Seems Sitecore just adds a Id to the url, but not create a campaign for
the 'TargeAudience_B' with that Id.
I use this sql query to check the visits data:
Select * From Visits join Automations on Visits.CampaignId =
Automations.CampaignId
Where Automations.data = '{EmailTemplateId}'
the data column on Automations table is the email template id of the
target audience.
Does any one know how to track one user's activities for multiple
campaigns, is that possible to do? Or is this something which needs to be
fix by Sitecore?
Any help will be much much appreciated.
Thanks

For instance: the displaced ball floats around. (Assuming we're talking

would be on earth, with gravity.)

IMDB API to search based on country of origin
IMDB API to search based on country of origin
As mentioned on the title, is there such API from IMDB that allows
developer to search a certain movie title / person based on the country of
origin.
For example:
I want to query the person John Doe, but only if he/she is German. Or if,
i want to search the title Snickers but only if such movie is German
movie.
I know there are several API that fetch data from IMDB such as:
[1]: http://www.imdb.com/xml/find?json=1&nr=1&tt=on&q=transformer
[2]: http://developer.rottentomatoes.com/docs
[3]: http://api.themoviedb.org/2.1/
Unfortunately, none of them provide options to search based on country of
origin.
Does anyone know any reliable data source which provide this option? Thx.

PHP regex to find value of Apache Tile attribute
PHP regex to find value of Apache Tile attribute
I want to use PHP to search a directory of files (views.xml files) and
pull out values from any attributes named "window_title_key".
The attributes look like this:
<put-attribute name="content" value="/WEB-INF/views/login/content.vm"
type="velocity" />
<put-attribute name="window_title_key" value="window_title_login_page"
type="string"/>
For each file, I want to ignore all lines except those that start with
<put-attribute name="window_title_key".
Then, on those lines, I want to extract the value of that attribute. In
this example, the value would be window_title_login_page.
I want the result to be an array of all of the values of all
window_title_key attributes.
What is the regex pattern I should use?
It should be flexible enough to allow for variable whitespace.

The attributes look like this:
<put-attribute name="content" value="/WEB-INF/views/login/content.vm"
type="velocity" />
<put-attribute name="window_title_key" value="window_title_login_page"
type="string"/>
For each file, I want to ignore all lines except those that start with
<put-attribute name="window_title_key".
Then, on those lines, I want to extract the value of that attribute. In
this example, the value would be window_title_login_page.
I want the result to be an array of all of the values of all
window_title_key attributes.
What is the regex pattern I should use?
It should be flexible enough to allow for variable whitespace.
Can't find action bar (Sherlock) inside root view
Can't find action bar (Sherlock) inside root view
I'm trying to find my activity's Action Bar's spinner so I can selectively
show and hide it (setNavigationMode does not work for my purposes). I
tried this code, but the Action Bar doesn't appear to be in my activity's
(which is an extension of SherlockFragmentActivity) root view.
private View findActionBarSpinner() {
View rootView = findViewById(android.R.id.content).getRootView();
List<View> spinners = traverseViewChildren( (ViewGroup) rootView );
return findListNavigationSpinner(spinners); // implement according to
your layouts
}
All I get for rootView is a FrameLayout containing the RelativeLayout
defined in my layout file (with only the elements within). I don't see
anything that looks like an Action Bar or a spinner, and and sure enough
traverseViewChildren (in the link above) returns an empty list.
I also tried, in the spirit of this answer, View rootView =
getWindow().getDecorView().findViewById(android.R.id.content).getRootView();.
The result was the same.
I'm making the call to findActionBarSpinner inside onOptionsItemSelected.
(Though I can't access it, the action bar is fully visible and working
properly at this point, so I doubt it's an issue of trying to access it at
the wrong part of lifecycle.)
Any ideas?

Decorating the ng-click directive in AngularJs
Decorating the ng-click directive in AngularJs
I've been looking into modifying the AngularJS ng-click directive to add
some additional features. I have a few different ideas of what to use it
for, but a simple one is to add Google Analytics tracking to all
ng-clicks, another is to prevent double clicking.
To do this my first thought was to use a decorator. So something like this:
app.config(['$provide', function($provide) {
$provide.decorator('ngClickDirective', ['$delegate', function($delegate) {
// Trigger Google Analytics tracking here
return $delegate;
}]);
}]);
But this won't work as decorators are fired on instantiation, not when the
expression in the directive is met. So in this case it would do the
analytics when an element with the directive loads, not when the element
is clicked.
So on to the real question. Is there some way for a decorator to get at
the element that the directive is instantiated on? If I could, from the
delegate, get to the element I could bind my own click event on it to
trigger in addition to the ng-click.
If not, how would you go about adding something on all ng-clicks?

C# - How to Doublebuffer Controls via Bufferimage?
C# - How to Doublebuffer Controls via Bufferimage?
I've read lots of attempts to double buffer C# Controls. But they just
don't work. I'm trying to do that with a TextBox. The background is
erased, the text drawn and the flickering is visible. So I thought the
only true way of doublebuffering is to use an off-screen image. I can't
paint everything by myself so I need to make my Control / TextBox paint
itself to the image ? How do I do that ? All I have is a hdc from the
image and I have somehow to smuggle it in a PAINTSTRUCT or PaintEventArgs
right ?
// protected override void WndProc(ref Message m)
// protected override void OnPaint(PaintEventArgs e)
// ...
These double buffering techniques were NOT working:
setting DoubeBuffered via reflection
SendMessage with WM_SETREDRAW
SuspendLayout / ResumeLayout
Anyways I would like to know how to double buffer in C# with an image. And
maybe someone else needs to use this technique as well.

Diameter protocol CCR request not routable
Diameter protocol CCR request not routable
I am using the jdiameter stack from http://i1.dk/JavaDiameter/ for my
diameter implementation. The initial CER request goes through fine but on
sending a CCR request i get a error as "not routable". Can anyone help me
out with this?. Also I am looking to build a Diameter call charging client
and have gone through mobicents, but am unable to get started on the same
due to lack of basic tutorials as to how to go about it. P.S. there is
already a similar question posted some time back but that failed to
resolve my query.

Draw a dashed and dotted bezier curve in QML
Draw a dashed and dotted bezier curve in QML
I've seen there is an example implementation of Bezier curvein QML, but
I'm looking for a hint how to implement dashed or dotted bezier curve
line. As far as I see, tha authors of Bezier curve example are using
QSGGeometryNode to store inside QSGGeometry with a QSGFlatColorMaterial
material applied on it. Then they simply create list of points and draw
segments between them.
Is it possible to store more than one QSGGeometry inside QSGGeometryNode?
(to be able to draw each "dashed" segment separately, or is there a
possibility to write a shader, which will be applied to
QSGFlatColorMaterial and will render this line as dashed?
Any hint would be highly appreciated! :)

Search for string and convert it to date
Search for string and convert it to date
Hello i have in one table string which looks like this xxxxxxxxx
day.month.year xxxxxxxxx. For date format is not used DD.MM.YYYY but is
used also D.M.YYYY, depends hov many numbers date has. Question is how to
search for string: left max 2 characters before first . then search for
cahracters between . and . and then search for 4 characters after second .
This will by numbers for day, month and year. When this values will be
know then those numbers convert to date. example: text 1.1.2013 text -
find particular numbers and create from this date. I have no possibility
to create separate column with date.
Any suggestion will be mostly welcome

WPF Login GUI for MySql Server
WPF Login GUI for MySql Server
Hi all I'm new to the C# world & visual studio 2012.....i've created a
database in MySql & have created several users with different permissions
to the only database on the server. I want to create a login GUI with WPF
which will allow any of the users i've created in MySql server to login.
Is this possible without writing the connection string with all the
usernames and passwords in the code? Any help will be appreciated.

Node JS, createServer, and the Event Loop
Node JS, createServer, and the Event Loop
Behind the scenes in node, how does the http module's createServer method
(and its callback) interact with the event loop? Is it possible to build
functionality similar to createServer on my own in userland, or would this
require a change to node's underlying system code?
That is, my general understanding of node's event loop is
Event loop ticks
Node looks for any callbacks to run
Node runs those callbacks
Event loops ticks again, process repeats ad-infinitum
What I'm still a little fuzzy on is how createServer fits into the event
loop. If I do something like this
var http = require('http');
// create an http server and handle with a simple hello world message
var server = http.createServer(function (request, response) {
//...
});
I'm telling node to run my callback whenever an HTTP request comes in.
That doesn't seem compatible with the event loop model I understand. It
seems like there's some non-userland and non-event loop that's listening
for HTTP requests, and then running my callback if one comes in.
Put another way — if I think about implementing my own version version of
createServer, I can't think of a way to do it since any callback I
schedule will run once. Does createServer just use setTimeout or
setInterval to constantly recheck for an incoming HTTP request? Or is
there something lower level, more efficient going on. I understand I don't
need to fully understand this to write efficient node code, but I'm
curious how the underlying system was implemented.
(I tried following along in the node source, but the going is slow since
I'm not familiar with the node module system, or the legacy assumptions
w/r/t to coding patterns deep in the system code)

ModalPopupExtender from Server Side Code in c#
ModalPopupExtender from Server Side Code in c#
I had a nightmare getting this going.
Adding the ModalPopupExtender to a form is easy, you drop it on and tell
it the two required controls parameters
PopupControlID="MyModalPanel" TargetControlID="ButtonToLoadIt" And it just
works fine, but is triggered by a client side click of the Target Control.
If you want to do some server side code behind??? how to do it ?

Parsing XML in Groovy with namespace and entities
Parsing XML in Groovy with namespace and entities
Parsing XML in Groovy should be a piece of cake, but I always run into
problems.
I would like to parse a string like this:
<html>
<p>
This is a <span>test</span> with <b>some</b> formattings.<br />
And this has a <ac:special>special</ac:special> formatting.
</p>
</html>
When I do it the standard way new XmlSlurper().parseText(body), the parser
complains about the   entity. My secret weapon in cases like this is
to use tagsoup:
def parser = new org.ccil.cowan.tagsoup.Parser()
def page = new XmlSlurper(parser).parseText(body)
But now the <ac:sepcial> tag will be closed immediatly by the parser - the
special text will not be inside this tag in the resulting dom. Even when I
disable the namespace-feature:
def parser = new org.ccil.cowan.tagsoup.Parser()
parser.setFeature(parser.namespacesFeature,false)
def page = new XmlSlurper(parser).parseText(body)
Another approach was to use the standard parser and to add a doctype like
this one:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
This seems to work for most of my files, but it takes ages for the parser
to fetch the dtd and process it.
Any good idea how to solve this?

of test, PHPUnit always hits 404 (observable by asserting the response
codes - the one I expect and the one that PHPUnit receives), thus failing
the tests.
I have added all code in respective files as this REST API's readme
instructs:
• I have added a module specific for REST: /application/modules/api. • In
my application.ini, I have the following:
autoloaderNamespaces[] = "REST_"
rest.default = "xml"
rest.formats[] = "json"
rest.formats[] = "xml"
resources.frontController.plugins.ErrorHandler.class =
"Zend_Controller_Plugin_ErrorHandler"
resources.frontController.plugins.ErrorHandler.options.module = "default"
resources.frontController.plugins.ErrorHandler.options.controller = "error"
resources.frontController.plugins.ErrorHandler.options.action = "error"
resources.router.routes.rest.type = Zend_Rest_Route
• In my application/bootstrap.php:
public function _initREST()
{
$frontController = Zend_Controller_Front::getInstance();
// set custom request object
$frontController->setRequest(new REST_Request);
$frontController->setResponse(new REST_Response);
$frontController->addModuleDirectory(APPLICATION_PATH . '/modules');
// Add the REST route for the API module only
$restRoute = new Zend_Rest_Route($frontController, array(),
array('api'));
$frontController->getRouter()->addRoute('rest', $restRoute);
}
• In my /application/modules/api/Bootstrap.php:
public function _initREST()
{
$frontController = Zend_Controller_Front::getInstance();
// Register the RestHandler plugin
$frontController->registerPlugin(new
REST_Controller_Plugin_RestHandler($frontController));
// Add REST contextSwitch helper
$contextSwitch = new REST_Controller_Action_Helper_ContextSwitch();
Zend_Controller_Action_HelperBroker::addHelper($contextSwitch);
// Add restContexts helper
$restContexts = new REST_Controller_Action_Helper_RestContexts();
Zend_Controller_Action_HelperBroker::addHelper($restContexts);
}
• Out of my own experiments, I have also added a line
$autoloader->registerNamespace('REST_') to my /public/index.php where
$autoloader refers to an instance of Zend_Loader_Autoloader.
• My test's location:
/tests/application/modules/api/controllers/RestClassTest.php • This is my
one of my tests for getAction():
public function testGetAction()
{
$this->request->setMethod('GET');
// Have tried other variations of URI too but all bear same result
(getting 404) in tests indicating that routing is not set at the
fundamental level.
$this->dispatch('/api/learn-to-rest?id=51fc287fc55ffc4006410bca');
$body = $this->getResponse()->getBody();
$json = json_decode($body, true);
$this->assertEquals('John Doe', $json['name']);
$httpResponse = $this->getResponse()->getHttpResponseCode();
$this->assertEquals(200, $httpResponse);
}
• And this is my getAction():
public function getAction()
{
$request = $this->getRequest();
$objectId = $request->getParam('id');
// Validation for ID
$this->_validateMongoObjectIdAction($objectId);
// Perform DB record selection
$records = new Db_Collection_Class(new Db_Mongo_Class);
$result = $records->findInCollection(array('_id' => new
MongoId($objectId)));
if ($result === null) {
// Source: http://www.w3.org/Protocols/HTTP/HTRESP.html
$this->getResponse()->setHttpResponseCode(404);
}
// Dispatch records in JSON format
$this->_helper->json($result);
}
It is true that I am setting a 404 for no-result-found situation but
confining specifically at getAction, it is hitting 404 with test for a
recognized valid ID as well.
I checked numerous resources (including the example provided by this API
and Matthew O'Phinney's post:
http://www.mwop.net/blog/228-Building-RESTful-Services-with-Zend-Framework.html)
and all instruct to follow the same things that I am already doing. It is
evident that I am missing something they are telling or am not
comprehending some factor. I'll be obliged if anyone guides me where I'm
doing what wrong.
Thanks in advance.
I am new to Zend Framework and am trying to implement a RESTful controller
in Zend and trying to write unit tests for my controller. I am following
