Click on NSBezierPath
I'm drawing a NSBezierPath line on my NSImageView. I'm creating
NSBezierPath object, setting moveToPoint, setting lineToPoint, setting
setLineWidth: and after that in drawRect of my NSImageView subclass I'm
calling [myNSBezierPath stroke]. It all works just like I want, but I
can't seem to use containsPoint: method... I tried implementing
if([myNSBezierPath containsPoint:[theEvent locationInWindow]]{
//do something
}
in -(void)mouseUp:(NSEvent*)theEvent of my NSImageView subclass but it's
never reacting and I'm sure I'm hitting that line... Am I doing something
wrong? I just need to detect if NSBezierPath is being clicked.
Cheers.

Model binder can't handle double.MAX string representation back to double?
Model binder can't handle double.MAX string representation back to double?
Right now I have a ViewModel with a property double Maximum. On the view
side it's kept in a hidden input.
When post backing the values, the binding silently fails. I had to put a
breakpoint on this line:
if(ModelState.IsValid)
and check which ModelState property had an error. Then I found that this
double Maximum property had an error with the following message:
The parameter conversion from type 'System.String' to type 'System.Double'
failed. See the inner exception for more information.
On the view side inspecting the HTML with Firebug I can see that the
hidden input has this value:
1.79769313486232E+308
which correctly represents double.MAX constant.
I found this Scott Hanselman post from 2005 which deals with something
similar:
Why you can't Double.Parse(Double.MaxValue.ToString()) or
System.OverloadExceptions when using Double.Parse
Is there something wrong with my app config or this direct conversion from
string back to double is not supported? I think it should handle it
without errors.
Note: I tried changing the hidden input value with Firebug and did as
Scott mentions on his post: I subtracted 1 from the last digit...
1.79769313486231E+308
and did a postback again just to find the model binder handled it
correctly this time.

All my columns in the database are varchar. zipcode is the primary and I
would make it INT but it doesn't allow there to be 0's at the beginning of
the zipcodes. So I changed it to varchar and it allowed it. Thanks for the

Arduino + bluetooth + power supply + switcher
Arduino + bluetooth + power supply + switcher
I'm completely new in this field, so I need your help!!
I'd like to remotely control inside the house (bluetooth or wifi) some
appliances (lamp, fan...).
I would like to have a controllable system from my Windows pc (C# as a
programming language) and from my tablets/smartphones (phonegap solution
'cause I have different OS). If the phonegap solution it is not possible
no problem. that's a surplus, I just need it for my pc.
I think that one idea could be having just one board with a bluetooth/wifi
module and connected to different high voltage output letting me the
choice of switching off/on some appliances.
The other idea could be having one board for each appliances but maybe
this would cost a lot.
Overall can I connect the bluetooth board/shield to different devices
without pairing them everytime?
If you can please suggest me some good tutorials and some good places
where I could buy everything :-)
Thank you very very much!!

When are global variables actually considered good/recommended practice?
When are global variables actually considered good/recommended practice?
I've been reading a lot about why global variables are bad and why they
should not be used. And yet most of the commonly used programming
languages support globals in some way.
So my question is what is the reason global variables are still needed, do
they offer some unique and irreplaceable advantage that cannot be
implemented alternatively? Are there any benefits to global addressing
compared to user specified custom indirection to retrieve an object out of
its local scope?
As far as I understand, in modern programming languages, global addressing
comes with the same performance penalty as calculating every offset from a
memory address, whether it is an offset from the beginning of the "global"
user memory or an offset from a this or any other pointer. So in terms of
performance, the user can fake globals in the narrow cases they are needed
using common pointer indirection without losing performance to real global
variables. So what else? Are global variables really needed?

Unique function to read different streams
Unique function to read different streams
I'm looking for a way to read file and stdin stream using a unique void
function in C. I'm trying to use this function:
#define ENTER 10 //'\n' ASCII code
........
void read(FILE *stream, char *string) {
char c;
int counter = 0;
do {
c = fgetc(stream);
string = realloc(string, (counter+1) * sizeof(char));
string[counter++] = c;
} while(c != ENTER && !feof(stream));
string[counter-1] = '\0';
}
but it's working only with stdin stream. When I'm using a text file, the
file content isn't visible outside the function. I'm calling this function
like:
read(stdin, inputString);
read(inputFile, fileContent);
and only works right in the first case.
P.S.: Initially, inputString an fileContent have been declared as
char *inputString = malloc(sizeof(char));
char *fileContent = malloc(sizeof(char));
and I know fgetc returns int, the char by char reallocation are expensive
(but I need to use only the necessary memory) and EOF or '\n' are stored
in string (but are replaced by 0-terminator after).

Weird behaviour with jQuery datepicker in IE10
Weird behaviour with jQuery datepicker in IE10
I have added a jQuery datepicker to my MVC application and it seems to be
working perfectly in all browsers except for Internet Explorer.
On click of the cell the calendar control appears but clicking through the
months using the navigation icons seems to stop after varying amount of
clicks. The date cells then become unclickable and I am unable to set the
date.
Has anyone ever seen this issue before? And if so was there a solution
available?
My javascript code is as follows:
$(document).ready(function () {
$('#expirydate').datepicker({ dateFormat: 'dd/mm/yy', changeMonth:
true, changeYear: true });
});
And my HTML is as follows:
<label for="expirydate">Expiry Date:</label>
<input type="text" id="expirydate" class="datepicker" name="expirydate"
/><br />

packageManager.getInstalledPackages(0) doesn't return all apps
packageManager.getInstalledPackages(0) doesn't return all apps
I'm using
PackageManager packageManager = getPackageManager();
List<PackageInfo> mApps = packageManager.getInstalledPackages(0);
to retrieve a list of all installed apps. However, the list doesn't
contain all installed apps, some (like Twitter, for example) are missing.
To test this, I'm using
int length = mApps.size();
for(int i=0; i<length; i++){
PackageInfo info = mApps.get(i);
Log.i(TAG, "Package: " + info.packageName);
}
com.twitter.android and others aren't among the logged strings, even
though they are installed on the phone.
P.S.: I've also tried
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> mApps =
getPackageManager().queryIntentActivities(mainIntent, 0);
which shows Twitter, but doesn't (obviously) return processes that can't
be launched via the launcher, such as "Download Manager" or "System UI". I
need a method that returns both system apps and third-party apps reliably.

Immidate command during MySQL Transaction
Immidate command during MySQL Transaction
During a sign up process, I'm using a Transaction to enclose all the
operations involved in the setup of an account so that in the event of a
problem they can be rolled back.
The last item that occurs is a billing process so that if payment is
successful, the Commit operation is called to finalise the account
creation, if say, the user's card is declined, I roll back.
However, I am wondering what the best way is to write a log of the
attempted billing to the database without that particular write operation
being 'covered' by the transaction protecting the other database
operations. Is this possible in MySQL? The log table in question does not
depend on any others. Holding on to the data in the application to write
it after the rollback operation is somewhat difficult due to legacy
payment libraries created before we started using transactions. I'd like
to avoid that if MySQL has a solution.

how to parse results of joint query in hibernate
how to parse results of joint query in hibernate
In my project I have 2 beans (Demande & Candidat ), and I want to execute
a join query with Hibernate like this:
String squery="select d.date_demande, c.nom, c.prénom from Demande d ,
Candidat c where d.id_candidat=c.id_candidat";
SQLQuery query=session.createSQLQuery(squery);
The issue is that I don't know which object this query returns. I want to
put the result of this query in a list so I can use it in a jsp file
easily.

Webapplication common resources & Loadbalance
Webapplication common resources & Loadbalance
I am about to implement load balancing with apache webserver and two
tomcat servers.
The war deployed on both tomcats has common resources like images and css
folders, which are quietly large, so if some change happens in image i
have to do a copy and past again in the other war file deployed.
I am looking out to try to map a fix directory for both the war files that
will fetch from common folder. (i.e Tomcat 1 and Tomcat 2 will access css
folder from C:\css\ same for images )
I tried writing servlet that deployed images but that was not feasible.
Any other way to work around for high availability for resource serving ?
Please Assist if you have any idea.

Unqualified IDs and Template Classes
Unqualified IDs and Template Classes
I've been writing a custom class for a circular list, called CList. I've
been basing it off a homework assignment I completed a long while ago with
a lot of copy paste so I don't exactly remember exactly everything I've
been writing works.
Anyway, simply trying to include the .h file causes me the error on the
using namespace std line:
main.cpp:11: error: expected unqualified-id before ';' token
As well as two errors pointing to a function in my code:
In file included from main.cpp:9:
CList.h:119: error: non-template 'CIterator' used as template
CList.h:119: note: use 'CList<T>::template CIterator' to indicate that it
is a template
This is the function in question:
template <class T>
typename CList<T>::CIterator<T> CList<T>::push(T const& v)
{
size++;
Node<T>* p = new Node<T>(v);
if (this -> size_ == 1)
{
head = p;
tail = p;
p -> next = p;
p -> prev = p;
}
else
{
tail -> next = p;
p -> next = head;
p -> prev = tail;
head -> prev = p;
tail = p;
}
return CIterator(p);
}
I don't really understand what the error here is. I am telling the
function to return a CIterator of a CList, and am denoting that this
function is part of the CList class. That is what I understand when I read
the line
typename CList<T>::CIterator<T> CList<T>::push(T const& v)
Why does it think that CIterator is the template when clearly T is the
template? I'm just confused.

Here is a piece of code:
int* linenump;

printf("----\n");
linenump = malloc(sizeof(int));
printf("*****\n");
The program only print out ---- then stopped, pop up a window says that
the program has stopped, I paste the code in VS then build&run it, no
errors, the program works fine.
It's a console application.
So, what I want to know is, in what situation that this will happen? and
how should solve it?

Did a simple deployment of sharePoint Hosted App from Visual Studio... it
worked - but I want to understand the limits of what I can do from visual
studio.
I see no aspx page cs codebehind in the solution. Any way to do that? I
added a c# class, but will I be able to reference it? so, If I want to
bind SPO List data to a asp.net gridview, where/how should I do that?

How to build a simple string from a multidimensional array?
How to build a simple string from a multidimensional array?
Basically, I have a multidimensional array that I need to build into a
simple string.
Quite an easy question, although it has been eating away at me for quite
some time now since I can't seem to nail it.
Here is an example of how my array could look with just 3 questions within
it:
[["question1","answer1","answer2","answer3","answer4"],["question2","answer1","answer2","answer3","answer4"],["question3","answer1","answer2","answer3","answer4"]]
For example, D.rows[0][0] would be "question1" and D.rows[2][3] would be
"answer3", just to clarify.
Here is how it must be saved into a string as:
question1,answer1,answer2,answer3,answer4
question2,answer1,answer2,answer3,answer4
question3,answer1,answer2,answer3,answer4
Each element must have a comma between them, and each question must be
separated by a line-break.
I had this working with a foreach loop in PHP, although I decided to
convert all my code to Javascript and I am no expert when it comes to
Javascript or multidimensional arrays.
Thanks in advance!

How does CUDA handle multiple updates to memory address?
How does CUDA handle multiple updates to memory address?
I have written a CUDA kernel in which each thread makes an update to a
particular memory address (with int size). Some threads might want to
update this address simultaneously.
How does CUDA handle this? Does the operation become atomic? Does this
increase the latency of my application in any way? If so, how?
Thank you very much!

unable to connect to ClearDB Mysql from NodeJS on Heroku server
unable to connect to ClearDB Mysql from NodeJS on Heroku server
ANy idea how can I connect from NodeJs to the Mysql ClearDB on Heroku?
I was able to connect to the ClearDB Mysql runing on Heroku from Navicat,
I even created a table called t_users. But I'm having problems connecting
from NodeJs from Heroku.
This is my code, it is very simple: everything works find until it tries
to connect to MySQL
web.js:
var express = require("express");
var app = express();
app.use(express.logger());
var mysql = require('mysql');
var connection = mysql.createConnection({
host : 'us-cdbr-east-04.cleardb.com',
user : 'b32fa719432e40',
password : '87de815a',
database : 'heroku_28437b49d76cc53'
});
connection.connect();
app.get('/', function(request, response) {
response.send('Hello World!!!! HOLA MUNDOOOOO!!!');
connection.query('SELECT 1 + 1 AS solution', function(err, rows, fields) {
if (err) throw err;
response.send('The solution is: ', rows[0].solution);
});
});
var port = process.env.PORT || 5000;
app.listen(port, function() {
console.log("Listening on " + port);
});
This is what I got when I run on the command line: Heroku config

Why does a wrong override compile ? (MinGW)
Why does a wrong override compile ? (MinGW)
I have this code :

};
class B : public A

virtual void operator()(std::complex<double>* input_spectrum,

I don't get why it compiles ? The const qualifiers are different, so it
should throw an error, doesn't it ?. Running under MinGW 4.8

Saving "post" link in Chrome
Saving "post" link in Chrome
So I've filled out a form and it's returned a result. Now if this was a
"get" request, I'd see all the parameters in the URL, and be able to send
the link to someone else to reproduce the result. However, I believe this
is sent as a post request, so sending the link just goes back to the
original page.
Is there anyway to generate a link that reflects the parameters sent for a
post request? I think even if it's redone as a get request it'll work
fine, the form probably won't care where it's getting it's data from.

C# calling external method (delegate) from within
C# calling external method (delegate) from within
I'm generating and executing C# from within a C# program using as
described here.
As you can see, one can call "Execute" method of the compiled code via
classType.GetMethod("Execute").Invoke(instance, args).
The variable args is an object array of parameters to be passed to the
Execute method. I've been able to pass things relatively easy and without
issue using this system.
Now here's the big issue... I need to pass a callback function (eg a
Delegate) so that the Execute method will be able to signal stuff to the
main program. I've been trying to pass a typed Delegate that matches the
signature, but it failed (wouldn't even run). Next I tried passing a
Delegate without specifying the type which also failed (this time it
failed at when the call was attempted). I also tried passing it as a
normal object and cast it back inside the generated code, but it didn't do
anything different.
Since I'm not this much into C#, I think I'm missing something very basic.
Also, I don't have a valid test case code...but it shouldn't be too
difficult to work with the link I provided above..

How can i fix it so i will be able to see Hebrew characters instead of
this unicoding?
Thanks!
I have a mysql database and i'm using phpMyAdmin. I have a table contains
names in Hebrew (defined as VARCHAR and "uft8_general_ci") I tried to
fetch these names and print them as JSON array using the following php
code:
// array for JSON response
$response = array();
// include db connect class
include 'db_config.php';
// connecting to db
//$db = new DB_CONNECT();
$mysqli = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);
/* check connection */
if ($mysqli->connect_errno) {
printf("Connect failed: %s\n", $mysqli->connect_error);
exit();
}
/* change character set to utf8 */
if (!$mysqli->set_charset('utf8')) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
} else {
printf("Current character set: %s\n", $mysqli->character_set_name());
}
// get all contacts from contacts table
$result = $mysqli->query("SELECT * FROM myList");
// check for empty result
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
$response[] = $row;
}
// echoing JSON response
echo json_encode($response);
} else {
// no contacts found
$response["success"] = 0;
$response["message"] = "No contacts found";
// echo no users JSON
echo json_encode($response);
}

How to get keys and values from a dictionary
How to get keys and values from a dictionary
So I have a dictionary that is set up like:
Dictionary<DateTime, List<Double>>
The date and times are months I pull from an excel spreadsheet and then my
integers is the dollar amount. The columns look like this:
7/1/10 | 6/1/10
----------------
100.00 | 90.00
----------------
3.00 | 20.00
----------------
35.00 | 10.00
and so on and so forth for about 6 months. I need to get these keys and
the values. I need to put it into my database. For example for the values
100.00, 3.00, 35.00 they all coordinate with month 7/1/10 (the first key
has the 3 Values under it and etc.)
Could someone just show me how to iterate over these things? When I
debugged my dictionary put's all the info in correctly but I can't pull
them back out.

Implementing colspan on DIVS

My requirement is to merge similar valued and sibling DIVS into single DIV
as colspan. For that I have an approach like below
$('#head > div').each(function(){
$(this).find('.l-item').each(function(){
var txt = $(this).text();
$(this).siblings().filter(function(){
return $(this).text() == txt;
});
});
});
It seems like it will mess with the DOM, any other solution for this please..

Applescript - Run Multiple Instances of an App in Mac OSX
Applescript - Run Multiple Instances of an App in Mac OSX
I was hoping one of you kind folks could help me write a script that would
open another instance of Transmission.
From my online research, I took a stab at making my own and compiled the
following script for AppleScript Editor.
do shell script "open -n -a '/Volumes/2 TB/App/Transmission.app'"
However, i get the following error message, "There is already a copy of
Transmission running. This copy cannot be opened until that instance is
quit."
Can anyone tell me what I'm doing wrong?
Thanks!

JS callback when ignoring geolocation permission request?
JS callback when ignoring geolocation permission request?
When utilizing JS geolocation on a web page, the browser asks the user if
they want to allow or deny the webpage to access their location.
navigator.geolocation.getCurrentPosition(showPositionFunction,
errorFunction);
The showPositionFunction is what is called if the user grants geolocation
access. errorFunction is called if the user deny's geolocation access or
if the geolocation fails for some reason.
But most browsers also allow you to ignore the geolocation permission
question. For Chrome and Firefox, you can simply hit the X button to close
the permission dialog, neither allowing or denying geolocation access. Is
there a callback for this event?

regex: plus sign vs asterisk
regex: plus sign vs asterisk
The asterisk or star tells the engine to attempt to match the preceding
token zero or more times. The plus tells the engine to attempt to match
the preceding token once or more.
Based on the definition, I was wondering why the plus sign returns more
matches than the asterisk sign.
echo "ABC ddd kkk DDD" | grep -Eo "[A-Z]+"
returns
ABC DDD
echo "ABC ddd kkk DDD" | grep -Eo "[A-Z]*"
returns ABC

I'm trying to create an editor that have several hotkeys. This editor will
be have some function each ke we press. (btw, sorry if my english bad :D )

ta.getInputMap().put(keyStroke_1, keyStrokeAndKey_1);

'Interesting' orthogonal martices?
'Interesting' orthogonal martices?
I'm working with an algorithm that takes as part of its input an
orthogonal matrix with real entries. I'm trying to understand how the
specification of this matrix affects performance of the algorithm. It's
very difficult to do this analytically, so I'm working experimentally for
now.
I'm loking for examples of orthogonal matrices that are in some sense
'interesting' or 'extreme'. Obviously the identity matrix is one choice.
Another choice might be the matrix that is 'least sparse' in the sense
that the sum of the absolute values of the entries is as large as possible
(is there a name for this?). Another choice is a random sample from the
Gaussian orthogonal ensemble.
Can anyone suggest some other examples?
Many thanks.

string letters = "a,b,c,d,e,f";
if (letters.Contains("a"))
{
return true;
}
if (letters.Contains("b"))
{
return true;
}
if (letters.Contains("c"))
{
return true;
}
I want to do away with having to have three compare lines of code.
Thanks!

Linux: Disable Laptop Touchpad Using In-Build Sensor
Linux: Disable Laptop Touchpad Using In-Build Sensor
These days many laptop devices come with a touchpad that have sensor next
to them. By double clicking these sensor (or single clicking on some of
them) the touch pad is disabled until the sensor is double clicked again.
However, this happens only in Windows.
Ever since I have switched to Linux (using Arch Linux this time) this
shortcut method does not work.
Although I have seen a couple of scripts to disable touchpad and some
packages available on the internet, it's good to be able to have it done
by an easy method as using the in-built sensor.
Anyone knows how we can do this?

Tooltip Not Showing Up When No Validation Error WPF
Tooltip Not Showing Up When No Validation Error WPF
I searched and did not see a solution.
I can only get the validation to show the tooltip if I do not set a
tooltip in the combo box tooltip property. I would like to see the
validation error tooltip when one is present otherwise show the tooltip
from the combobox property. The validation tooltip shows up fine when I
remove the text from the tooltip property (i.e. from the property panel
for the combo box).
The XAML in Application.Resources (App.XAML)for the tooltip to show the
validation error is
<Style x:Key="StandardComboBoxStyle" TargetType="{x:Type ComboBox}">
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="True">
<Setter Property="ToolTip" Value="{Binding
RelativeSource={x:Static RelativeSource.Self},
Path=(Validation.Errors)[0].ErrorContent}"/>
</Trigger>
</Style.Triggers>
</Style>
I also use a validation template for the Combobox as follows. This is in
the UserControl.Resources section within the user control cs file.
<ControlTemplate x:Key="comboBoxValidationTemplate">
<DockPanel Name="myDockPanel">
<Border BorderBrush="Red" BorderThickness="3">
<AdornedElementPlaceholder Name="MyAdorner" />
</Border>
<TextBlock Text="*" FontWeight="Bold" FontSize="18"
Foreground="Red" DockPanel.Dock="Left" />
</DockPanel>
</ControlTemplate>
The control itself is defined as follows. Note that there are other
references not defined here (but hopefully not pertinent - feel free to
let me know if questions).
<ComboBox x:Name="ExposureTime" SelectedValuePath="Content"
Text="{Binding ExposureTime, Mode=TwoWay,

BlackBerry 10: Load GroupDataModel data into a JSON file?
BlackBerry 10: Load GroupDataModel data into a JSON file?
I have a ListView in QML using a cpp GroupDataModel that is created from a
.json file in the assets folder. Items from this ListView are removed and
added to. In cpp how do I get the GroupDataModel data into the JSON file?
I know there is this:
JsonDataAccess jda;
jda.save(huh?, "/app/native/assets/employees.json");
How do I get the GroupDataModel data into a QVariant to put in the first
parameter of that function? I can't just stick my m_model GroupDataModel
in there; it causes an error.

Toggle state in c# - wpf
Toggle state in c# - wpf
I want to make a function to work in toggle(switch) mode when i press a
key and i really can't figure how to do it. I tried lots of ways and only
the "RegisterHotKey" method is working fine. But "RegisterHotKey" is
overwriting the mapped key from the game and this is not what i need. So
i'm trying to use "GetKeyState". The code below it's only working for one
position no matter what i change...:
private void mw_KeyDown(object sender, KeyEventArgs e){
bool toggle = true;
bool sw = (toggle = !toggle);
int tog = (GetKeyState(Key.Tab));
if ((tog & 1) == 1)
{
if (sw)
{
System.Windows.MessageBox.Show("go to second position...!");
}
}
else
{
System.Windows.MessageBox.Show("go to first position...!");
}
}
Any idea or suggestion how can i do this ?

Installation error mySQL with visual c++ 2010
Installation error mySQL with visual c++ 2010
So I've just installed mySQL (5.6) to use with visual c++ 2010 and i've
encountered an error.
I'm using the tutorial located here:
http://dev.mysql.com/doc/refman/5.6/en/connector-cpp-apps-windows-visual-studio.html
At the part where it states to include the directory c:/Program
Files/mySQL/lib/opt I found that my installation doesn't have this
directory. The only lib folder that contains an opt folder in my mySQL
installation is the folder under C:\Program Files\MySQL\Connector C++
1.1.3\lib\opt
Should I be linking this file to the additional directoried, or have I
done something wrong?
I ask that you don't refer me to some tutorial and instead provide a
step-by-step explanation. I have been looking at quite a few tutorials but
they all seem to be using older version of both mySQL and VC++.
Thank you for your time.

Connected via SSH Tunnel, but IP address stays the same
Connected via SSH Tunnel, but IP address stays the same
I have installed SSH Tunnel on my phone, and can connect to an ssh account
I created on my server. Whenever I enable sshtunnel, it says it's
connected, but the ip address does not change. I created a simple php-page
on my webserver that shows the ip address plus current time. The time is
updated each time, so it's not a caching problem.
How can I get this working?

Convert pinyin to Chinese Character
Convert pinyin to Chinese Character
I want to take pinyin (english) as an input and return Chinese characters
that user can choose from. I saw that this has been implemented in many
place (support by OS keyboards and various websites), but can't find a
library to do it.
Or possibly even doing it myself if it's not that complex or require large
amount of data.

Remove duplicate string in an array
Remove duplicate string in an array
i'm new to c++ and i'm looking for a way to remove duplicate strings from
an array of strings that looks like this: string exempleArray[]=
{"string1", "string2", "string1"}; after the code it should look like
this: "string1", "string2", but the order doesn't matter at all. Thanks a
lot for your time.

Phonegap camera crash on android 4.1.2, samsung galaxy s3, HTC
Phonegap camera crash on android 4.1.2, samsung galaxy s3, HTC
I think a lot of developers are familier with this problem of phonegap
crashes/restarts after getting a picture from camera / library on android
4.1.2.
After many searches of many solutions I want to put some order into this
problem and I wish you could help me understand what is the current
solution. Note: the current stable phonegap version is 2.9.0.
Using fileURI and not dataURL, because the encoded base64 is too big for
the DOM to handle.
Editing (not via phonegap build config.xml) the android manifest file and
add the following line to every activity:
android:alwaysRetainTaskState="true" android:launchMode="singleTask".
Limit the resolution using targetWidth/targetHeight, because the image is
to big which causes memory over load. and reducing quality..
Switch off the
"Do not keep actitivies"
option in android settings.. which is ofcourse not a real solutions
becaues we can't ask users to do that..
Again, editing the android manifest (with discarding phonegap build
service) and add:
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"
<uses-feature android:name="android.hardware.camera"
android:required="false"/>
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="10"/>
<activity android:configChanges="orientation|keyboardHidden" />
Using an external camera plugin (not phonegap's):
links to all these solutions are here:
http://community.phonegap.com/nitobi/topics/phonegap_camera_crash_on_android_4_1_2_samsung_galaxy_s3_htc
Now.. After this literature review.. Does anyone know which combination
works? please help!

How to check if a local user account still have the same password
How to check if a local user account still have the same password
I have a PowerShell script which does the following on Windows 7 computers:
Get a random password from a secure server-side application
reset the password of a specific local user account using this password value
As a next step, I want to periodically check if the password saved on the
server is still valid. For now, I am using ValidateCredentials from
System.DirectoryServices.AccountManagement.PrincipalContext (see
Powershell To Check Local Admin Credentials) but it involves to unencrypt
the password and send it back to the computer just for this purpose.
Do you see any better way to check if password is still valid avoiding to
use clear text password ? Is it possible to compare some hash, or anything
else ?
Regards.

why buffer memory allocation error in opencl
why buffer memory allocation error in opencl
I execute the OpenCL program on an NDRange with a work-group size of 16*16
and work-global size of 1024*1024. The application is matrix
multiplication. When the two input matrix size are both little, it works
well. But when the size of input matrix becomes large, for example, larger
than 20000*20000, it reports error "CL_MEM_OBJECT_ALLOCATION_FAILURE" in
the function of enqueuendrangekernrl.
I am puzzled. I am not familiar with memory allocation. What's the reason?

How to get web service sub group XML data as a list?
How to get web service sub group XML data as a list?
Sub XML elements are returning as a long strings of x = "y" in a list with
a length of 1. How can I get sub xml elements to return into a useful data
set so I don't have to write string parsing code?
Details:
I call a web service with suds as normal like this:
myWebServiceData=client.service.getMethod("P1", "P2", "P3")
It Returns a dictionary as I would like however it looks like this:
myWebServiceData = { elm1: "data1", elm2: "data2", elm3: "[(data3){ elm4 =
data4 elm5 = data5 elm6 = data6 }]
So any data under data4 is a list with a length of 1. like this:
print myWebServiceData['elm4'][0]
elm4 = data4 elm5 = data5 elm6 = data6
However my xml looks like this (as seen in my logger):
<elm1>data1</elm1>
<elm2>data2</elm2>
<elm3>
<elm4>data4</elm4>
<elm5>data5</elm5>
<elm6>data6</elm6>

how to hide spinner after the content loads
I'm using pjax to load content and while the content is loading, I show a

$('a[data-pjax]').pjax().live ("click", function () {

This works fine, however, after the content loads the loader still stays
there.
Where should I call $(#loader).hide() to hide the loader after the content

How to create variable name with integer appended to the end?
How to create variable name with integer appended to the end?
I want to create a for loop that will fill a bunch of arrays with data in
c++. Now to save space and in the future once more arrays are added which
they will, I have the for loop. Each array for demonstration purposes is
called Array# (# being a number) The point of the for loop would be to set
a constant with maximum arrays, then cycle through each array filling by
appending i to the end of the Array name.
For example in pseudo code:
for (i = 1; i < numberofarrays; i++)
{ fill (Array & i) with ("Array" & i & "-default.txt")}
