How to expense $(a+b)^\alpha$ into multinomial with $\alpha \in \mathbb{R}$?
As we all know, the binomial expension is as follows $$ (a+b)^2 = a^2 +2ab
+b^2. $$ When the power number is a real number, not a integral, how to
expense $(a+b)^\alpha$ into multinomial with $\alpha \in \mathbb{R}$?

Does anyone have any idea how to run an interpolation search on a linked list in C++?
Does anyone have any idea how to run an interpolation search on a linked
list in C++?
int List::interpolationSearch(int id){
Node low = head;
Node mid;
Node high = tail;
}
I don't have any code, I just have absolutely no idea how I would do this
with the exception of assigning a few temporary nodes to the head and the
tail in order to set the the search range into which I would run the
interpolation. Basically this is all I've been able to come up with by
observing the interpolation search used with arrays. With those three
things in mind, I'm searching for an id, but here's where the problem
comes in. How do I know where to tell the method where to start searching.
I've seen the code for an array but I can't figure out how to do it here.

Disable right click menu on click
Disable right click menu on click
I am trying to build a minesweeper game with php and jquery. This means I
want the user to be able to right-click elements to mark areas as a
potential bomb or a questionmark. Now I have the right click event and the
code works, however if I don't alert anything I get the menu with inspect
element etc. I've tried throwing in some return false's but they haven't
helped. How can I stop the menu appearing on right-click?
$('.overlay').mousedown(function(event) {
switch (event.which) {
case 1:
//left click code
break;
case 3:
theID = event.target.id;
if ($('#'+theID).is(":visible") &&
$('.bomb_'+theID).css("visibility") == "hidden"
&& $('.mystery_'+theID).css("visibility") == "hidden"){
$('#'+theID).css("background", "none");
$('.bomb_'+theID).css("visibility", "visible");

Have tried to add event.preventDefault(); under the mousedown function but
this doesn't change anything. Also tried it under case 3:.

Access Jquery UI using primefaces
Access Jquery UI using primefaces
I am building a JSF application and want to convert a simple h:link to
look like a button using jquery ui button widget. I am using JSF2 and
primefaces 3.5.
I manually added the jquery-ui.js and have the following xhtml:
<h:link styleClass="linkGr"
outcome="#{listadoUsuario.verUser(user.username)}">ver</h:link>
<script>$(".linkGr").button({icons: {primary: "ui-icon-pencil"},text:
false});</script>
Having this in a page works fine, but in other pages, I see the following
error:
TypeError: Object function (f,h,e){var
g=f.split(".")[0],j;f=f.split(".")[1];j=g+"-"+f;if(!e){e=h;h=b.Widget}b.expr[":"][j]=function(k){return
!!b.data(k,f)};b[g]=b[g]||{};b[g][f]=function(k,l){if(arguments.length){this._createWidget(k,l)}};var
i=new
h();i.options=b.extend(true,{},i.options);b[g][f].prototype=b.extend(true,i,{namespace:g,widgetName:f,widgetEventPrefix:b[g][f].prototype.widgetEventPrefix||f,widgetBaseClass:j},e);b.widget.bridge(f,b[g][f])}
has no method 'extend'
I noted that this happens in pages where primefaces adds the
jquery-plugins.js.
I tried not including the jquery-ui javascript manually since I see the
jquery-plugins adds the button widget, but the problem is when adding
jquery-plugins (not including jquery-ui.js) I cannot see how to convert
the link to a button. The function button is not available in $. Can
somebody guide me on how to use primefaces included button method?
Thanks in advance!

Function with multiple if or with a "big" return?
Function with multiple if or with a "big" return?
I would like to know if one of this two solution is better than the other :
Version 1:
bool myFunction()
{
if (A)
return false;
if (B)
return false;
if (C)
return false;
if (D)
return false;
return true;
}
Version 2 :
bool myFunction()
{
return (!A && !B && !C && !D);
}
I guessed that version 2 may be a bit less efficient as we may have to
calculate the whole boolean expression to know if it's true or false. In
the first version, if A is false, it returns false, without calculating B,
C or D. But I find second version much more readable.
So what is the best way to do that ?
Thank you.

FullCalendar no refetch events
I have worked with fullcalendar smoothly for a while, now I feel the need
to implement some changes. I need to filter the events, this has been
helpful http://jsfiddle.net/QMyFu/337/, but I can not reset the filters
and redisplay all events,
javascript code:
$('#boton').click(function(){
$("#calendar").fullCalendar( 'refetchEvents' );
});
html code:
<button id="boton">Reload</button>
here I made a fiddle http://jsfiddle.net/pablop22/eT26Q/2/
any suggestions are welcome

Where Does Direct3D11 Allocate Resource Objects?
Where Does Direct3D11 Allocate Resource Objects?
I've been reading up on Direct3D11 a lot (including right here on stack
overflow!) and in all my research I haven't been able to conclusively
answer this question:
When a Resource object (i.e. a Buffer or a Texture object) is created, for
example with pDevice->CreateBuffer(), where is it stored? On system RAM or
on the GPU's Video-RAM? Or am I entirely misunderstanding the fundamental
nature of what a Resource object is?
Obviously whatever data you populate the resource with (such as vertex and
index arrays) is stored wherever you - the programmer - placed it, but
once you map that data to the Resource where is it copied? (I'm assuming
that, since Resources have to be mapped and unmapped for read/write
protection the mapped data is in fact copied, perhaps to VRAM). Moreover,
where is the Resource object itself instantiated?
Thanks in advance for any and all help!

binding value of text box to an object's property on canvas
binding value of text box to an object's property on canvas
I will appreciate it if experts could give me direction on following
scenario?
Consider a set of entries or we can just focus on one edit box for sake of
simplicity which its input has to be bound to a canvas. let's say user has
to be able to modify the angle of a line in the edit box using keyboard
while this edit box having two arrows (up/down arrow to increase or
decrease a value in the edit box) so mouse would be another option to
change the value and also losing focus should be the third element of
affecting line on canvas. this works almost but my major challenge here is
that sometimes user might remove the value from text box and re-enter a
new value. this is affecting line (or arc or any object) to disappear. how
can this issue be addressed and resolved?
Any advice will be appreciated.

Magento IWD Onepage Checkout and SagePay Issue
Magento IWD Onepage Checkout and SagePay Issue
We have a site developed in Magento with the SagePay Payment Gateway
Integration. With the default Magento Checkout, the Payment is working
fine. But as soon as we turn on the IWD Onepage Checkout extension, we are
not getting any response from the Sagepay server. Instead we are getting
the following error. "Payment has failed, please reload checkout page and
try again. Your card has not been charged."
We really appreciate your help to solve this problem.

then it will auto send the form to gmail when i run the php page, it will

Programming languages without static properties/methods?
Programming languages without static properties/methods?
Well I wonder if there are OO programming languages that do not have
statics in their language construct(either static keyword or anything
equivalent to declare something as static), therefore eliminating the
presence of static properties/methods. Statics are not really OOP, they
are procedural code in disguise and usually are considered bad smells in
OO software.
If a language has powerful dependency injection support while does not
support statics/globals, it will enforce way better OO practices. I
personally think in Java and C# statics should be removed from language
core by their next releases. But until then, I'd like to know if there
already exist programming languages that already eliminate the presence of
static bad smell?

QSorting an array of doubles
QSorting an array of doubles
I'm new to using qsort, and I'm attempting to qsort a predefined array of
doubles, unfortunately the result I receive is all 0's after the array has
been sorted using qsort. I'm completely lost, and any advice would be
greatly appreciated. Here is the code I am using to sort this array of
doubles.
static int compare (const void * a, const void * b){
if (*(const double*)a > *(const double*)b) return 1;
else if (*(const double*)a < *(const double*)b) return -1;
else return 0;
}
double stuff[] = {255, 1, 5, 39.0};
qsort(stuff, 4, sizeof(double), compare);
int i;
for(i = 0; i < 4; i++){
printf("%d %s", stuff[i], " ");

How can I restructure HTML to remove nested spans using JavaScript?
How can I restructure HTML to remove nested spans using JavaScript?
I need to use JavaScript to reformat input HTML so that the resulting
output HTML is always a sequence of <p> nodes containing only one or more
<span> nodes and each <span> node should contain exactly one #text node.
To provide an example, I'd like to convert HTML which looks like this:
<p style="color:red">This is line #1</p>
<p style="color:blue"><span style="color:yellow"><span
style="color:red">This is</span> line #2</span></p>
To HTML which looks like this:
<p style="color:red"><span style="color:red">This is line #1</span></p>
<p style="color:red"><span style="color:red">This is</span><span
style="color:yellow"> line #2</span></p>
Additional, somewhat tangential information:
The text is within a TinyMCE editor. The HTML needs to conform to this
pattern to make the application more usable and to provide a PDF output
engine with usable HTML (wkhtmltopdf has line height issues if the HTMl
gets too complex and nested spans cause editing in TinyMCE to be
non-intuitive)
jQuery is not available. Prototype.JS is available in the parent window
but not directly in this document. I'm capable of reformatting jQuery code
to pure JavaScript myself but can't actually use jQuery in this instance
:-(
Yes, I have existing code. The logic is clearly so horribly wrong that
it's not worth sharing right now. I'm working to improve it right now and
will share it if I can get it even reasonably close so it would be useful
I really do know what I'm doing! I've just been staring at this code too
long and so the proper algorithm to use is evading me right now...

Visual C , Arrays as field variables
Visual C , Arrays as field variables
I'm writing a program for opinion poles and I use the class 'Person',
class Person
{ protected: //field variables
int a; //just an example without importance
...
int answer[Nquestions]; //Nquestions is a constant. answer = {0,2}.
public: //constructor + methods
};
The compiler doesn't accept the array. 'Mixed types non supported', it
says. Is there a workaround of this problem?
Thanks and regards
Uwe

How to create a CouchDB View to join documents based on multiple, non-unique fields
How to create a CouchDB View to join documents based on multiple,
non-unique fields
I have a database with documents in the following forms:
{"Type" : "A", "Date": "2013-09-19", "Week" : "A", "Day" : "Mon"}
{"Type" : "B", "Week" : "A", "Day" : "Mon", "Class" : "xyz"}
How do I create a view that will list all the classes (from doc.Type =
"B") for a specific date (from doc.Type = "A")? Essentially it means
matching the "Week" and "Day" fields. I have found examples (mostly based
on Christopher Lenz's solution) but these are matching based on just one
field being matched, which is unique in one of the document types.

Joining 2 Database Tables Getting A Sum Value Output
Joining 2 Database Tables Getting A Sum Value Output
I am wanting to group values together based on which user it assigned to.
Here are the tables:
TABLE1 ID, COMPANY_ID, OPPORTUNITY, DATE_CREATE
TABLE2 ID, ASSIGNED_BY_ID
The two fields that link the two tables together are: TABLE1 > COMPANY_ID
and TABLE2 > ID
Basically I need to do a statement similar to this:
SELECT SUM(OPPORTUNITY) AS total FROM table1 WHERE DATE_CREATE BETWEEN
'$fromdate' AND '$todate' AND ASSIGNED_BY_ID=1 FROM table2
I know I have to join the two tables together where COMPANY_ID from table1
= ID from table2
But I have no idea how to impliment this in the statement.
Any help would be appreciated.
Thanks, Andy

dividing two variables in javascript
dividing two variables in javascript
ok, so I am trying to make a midpoint calculator in JavaScript for fun and
to practice with the language, The formula is pretty simple, it is just x1
+ x2 / 2 and y1 + y2 / 2, I want the user to be able to define the x and y
coordinates, and this is what I have come up with:
alert("welcome to nate's midpoint calculator!");
var x1 = prompt("type your first x coordanate!");
var y1 = prompt("excelent!, now your first y coordanate!");
var x2 = prompt("now type your second x coordanate!");
var y2 = prompt("and finally, your last y coordanate!");
var midText = ("your midpoints are: ");
var comma = (",");
var exclam = ("!");
var two = (2)
var x1x2 = (x1 + x2 / two);
var y1y2 = (y2 + y2 / two );
alert(midText + x1x2 + comma + y1y2 + exclam);
for some reason, this is not calculating correctly and turning in wrong
answers, go ahead and try it out. it may be some weird misstype from me, I
am fairly new to javascript, only having worked with the language for an
hour or two. any help would be very much appreciated! thanks in advance!

for some reason, this is not calculating correctly and turning in wrong

how to position column names vertically in datagridview in vb.net
how to position column names vertically in datagridview in vb.net
I appologise in advance if my question may appear silly to you but I have
a problem with positioning column names in a dataGridview vertically. I'm
populating DataGridView using flowing code:
Dim StrQwery As String = "SELECT * FROM employees WHERE employee_id =
(select MAX(employee_id) FROM employees AND registered = 'UNREGISTERED';
Dim smd As MySqlCommand
smd = New MySqlCommand(StrQwery, myconn)
smd.CommandType = CommandType.Text
Dim da As New MySqlDataAdapter(smd)
Dim cb As New MySqlCommandBuilder(da)
Dim ds As New DataSet()
da.Fill(ds)
GridView1.DataSource = ds.Tables(0)
If n = 1 Then
If Not Page.IsPostBack Then
GridView1.DataBind()
End If
Else
GridView1.DataBind()
End If
everything works perfectly except that I need to position account
attributes like name, position, ID number etc not horizontally but
vertically. Something like this:
|NAME | John |
|SURNAME | Philips|
|POSITION| Manager|
and I can't find a way how to do it. Can anyone give me a hint in my
problem please?
many thanks in advance.

Setting up web payment using paypal
Setting up web payment using paypal
I'm working on a project and they have are planning to add a feature web
payment. I'm glad to say that our client is a technical person and told me
to use the paypal. This is my first time integrating a web payment. I've
read some docs in developers.paypal and i'm planning to use the paypal
express checkout.
Furthermore I'll be developing this using only client side (Angularjs), is
it right decision for me to use paypal express checkout? Will I encounter
some security issue here since its client side? The main idea is upon
successful payment I have to sync an http request that will trigger that
the user has paid.
Sample idea
.success(function(){
$http.post(...)
});

android receives updates from MSSQL database
android receives updates from MSSQL database
I create a native Android app for a university (Java). This app should
show some data (exams, grades etc.) and implements a chat. All this data
is stored on a MSSQL-Server. I am downloading this data via JSON.
My current problem is the chat and update function. Does anyone know how
to realise a Java webservice where the clients can register and the
webservice is checking on the database, if there is an update and/or new
message.

Application is being killed while on background
My application always ends at some point while on background. I have read
that when the cpu usage of the application is low, the application is
being killed automatically. I already included a partial wake lock on my
onCreate method in my application using this code:
powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
"MyWakeLock");
Then on pause:

Log.w("OnPause", "OnPause");
}
I really don't know how to prevent my application being killed. I also
tried using full wake lock but it is deprecated. Any ideas on how will I
keep my application alive on background? I never want my application to be
killed while on background. Thanks!

Currently, I'm matching to the regex:

Which works, except for instead of void <init>(java.lang.String) I just
get void (java.lang.String).
I'm a bit mistified where <init> has gone off too...I've tried several
different ways to coax it back, but so far no luck.
Thanks folks!

Count the number of unique words and occurrence of each word in this program?
Count the number of unique words and occurrence of each word in this program?
CSCI-15 Assignment #2, String processing. (60 points) Due 9/23/13
You MAY NOT use C++ string objects for anything in this program.
Write a C++ program that reads lines of text from a file using the
ifstream getline() method, tokenizes the lines into words ("tokens") using
strtok(), and keeps statistics on the data in the file. Your input and
output file names will be supplied to your program on the command line,
which you will access using argc and argv[].
You need to count the total number of words, the number of unique words,
the count of each individual word, and the number of lines. Also, remember
and print the longest and shortest words in the file. If there is a tie
for longest or shortest word, you may resolve the tie in any consistent
manner (e.g., use either the first one or the last one found, but use the
same method for both longest and shortest). You may assume the lines
comprise words (contiguous lower-case letters [a-z]) separated by spaces,
terminated with a period. You may ignore the possibility of other
punctuation marks, including possessives or contractions, like in "Jim's
house". Lines before the last one in the file will have a newline ('\n')
after the period. In your data files, omit the '\n' on the last line. You
may assume that the lines will be no longer than 100 characters, the
individual words will be no longer than 15 letters and there will be no
more than 100 unique words in the file.
Read the lines from the input file, and echo-print them to the output
file. After reaching end-of-file on the input file (or reading a line of
length zero, which you should treat as the end of the input data), print
the words with their occurrence counts, one word/count pair per line, and
the collected statistics to the output file. You will also need to create
other test files of your own. Also, your program must work correctly with
an EMPTY input file – which has NO statistics.
Test file looks like this (exactly 4 lines, with NO NEWLINE on the last
line):
the quick brown fox jumps over the lazy dog.
now is the time for all good men to come to the aid of their party.
all i want for christmas is my two front teeth.
the quick brown fox jumps over a lazy dog.
Copy and paste this into a small file for one of your tests.
Hints:
Use a 2-dimensional array of char, 100 rows by 16 columns (why not 15?),
to hold the unique words, and a 1-dimensional array of ints with 100
elements to hold the associated counts. For each word, scan through the
occupied lines in the array for a match (use strcmp()), and if you find a
match, increment the associated count, otherwise (you got past the last
word), add the word to the table and set its count to 1.
The separate longest word and the shortest word need to be saved off in
their own C-strings. (Why can't you just keep a pointer to them in the
tokenized data?)
Remember – put NO NEWLINE at the end of the last line, or your test for
end-of-file might not work correctly. (This may cause the program to read
a zero-length line before seeing end-of-file.)
This is not a long program – no more than about 2 pages of code
Here is what I have so far:
#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
#include<cstring>
using namespace std;
void totalwordCount(ifstream &inputFile)
{
char words[100][16]; // Holds the unique words.
char *token;
int totalCount = 0; // Counts the total number of words.
// Read every word in the file.
while(inputFile >> words[99])
{
totalCount++; // Increment the total number of words.
// Tokenize each word and remove spaces, periods, and newlines.
token = strtok(words[99], " .\n");
while(token != NULL)
{
token = strtok(NULL, " .\n");
}
}
cout << "Total number of words in file: " << totalCount << endl;
}
void uniquewordCount(ifstream &inputFile)
{
char words[100][16]; // Holds the unique words
int counter[100];
char *tok = "0";
int uniqueCount = 0; // Counts the total number of unique words
while(!inputFile.eof())
{
uniqueCount++;
tok = strtok(words[99], " .\n");
while(tok != NULL)
{
tok = strtok(NULL, " .\n");
inputFile >> words[99];
if(strcmp(tok, words[99]) == 0)
{
counter[99]++;
}
else
{
words[99][15] += 1;
}
uniqueCount++;
}
}
cout << counter[99] << endl;
}
int main(int argc, char *argv[])
{
ifstream inputFile;
char inFile[12] = "string1.txt";
char outFile[16] = "word result.txt";
// Get the name of the file from the user.
cout << "Enter the name of the file: ";
cin >> inFile;
// Open the input file.
inputFile.open(inFile);
// If successfully opened, process the data.
if(inputFile)
{
while(!inputFile.eof())
{
totalwordCount(inputFile);
uniquewordCount(inputFile);
}
}
return 0;
}
I already took care of how to count the total number of words in the file
in the totalwordCount() function, but in the uniquewordCount() function, I
am having trouble counting the total number of unique words and counting
the number of occurrences of each word. Is there anything that I need to
change in the uniquewordCount() function?

I already took care of how to count the total number of words in the file
in the totalwordCount() function, but in the uniquewordCount() function, I
am having trouble counting the total number of unique words and counting
the number of occurrences of each word. Is there anything that I need to
change in the uniquewordCount() function?
What is required to build up a basic sqlite database server on my laptop
What is required to build up a basic sqlite database server on my laptop
Thank you for the time reading this.
I am planning on creating an Android app that is communicating with my own
SQLite database server\webpage that is located on my private laptop. I
have no previous knowledge/experience with PHP nor hosting a webpage in
this case. My question is what is required to make the most basic online
database server so I could easily and very basically request and fetch
SQLite queries within the Android app from the database that is on my
laptop. Are there any programs I have to own? Also my first intentions is
for it to work on my local network(My Wifi at home), and then make it
global.
Any help is appreciated, Thanks.

Soundcloud api - tracks info - replace file
Soundcloud api - tracks info - replace file
A simple question about the soundcloud API, but I can't fnd this info, and
can't make the test by myself since I don't have a pro account: If a user
update (replace) a file, how could I know it? Is the id replaced? Or the
date changed? Thanks

basic_string of unsigned char Value Type
basic_string of unsigned char Value Type
So, string comes with the value type of char. I want a string of value
type unsigned char. Why i want such a thing is because i am currently
writing a program which converts large input of hexadecimal to decimal,
and i am using strings to calculate the result. But the range of char,
which is -128 to 127 is too small, unsigned char with range 0 to 255 would
work perfectly instead. Consider this code:
#include<iostream>
using namespace std;
int main()
{
typedef basic_string<unsigned char> u_string;
u_string x= "Hello!";
return 0;
}
But when i try to compile, it shows 2 errors, one is _invalid conversion
from const char* to unsigned const char*_ and the other is initializing
argument 1 of std::basic_string<_CharT, _Traits,
_Alloc>::basic_string...(it goes on)
EDIT: "Why does the problem "converts large input of hexadecimal to
decimal" require initializing a u_string with a string literal?" While
calculating, each time i shift to the left of the hexadecimal number, i
multiply by 16. At most the result is going to be 16x9=144, which
surpasses the limit of 127, and it makes it negative value.
So, what should i do?

Reading WebGLRenderTarget pixel data in Three.js
Reading WebGLRenderTarget pixel data in Three.js
I have created a sculptable terrain with height displacements using GLSL
shaders in Three.js. It's done via two THREE.WebGLRenderTargets to
accumulate the sculpted heights in a fragment shader. The vertices of the
mesh are then displaced with this texture via vertex texture fetching in a
vertex shader.
However, I need the updated terrain to be a collision for a CPU-based
rigid body system. How do I get the updated height data from a
THREE.WebGLRenderTarget?

Use java to perform binary shifts
Use java to perform binary shifts
I have to take a binary data in java and perform shifts on it. For e.g.
11110000 when I right shift it by 2 , i.e. 11110000>>00111100
The problem is that, I don't know how to store such a data in Java, as the
byte type converts it to decimal format. I need to use the bit at position
6 and XOR it with some other value.
I just need to know how I can achieve the ability to store binary data and
perform the required shifts.

what is wrong with my method for avg?
what is wrong with my method for avg?
Yes, I know there are a lot of methods here. It's part of the assignment.
In this code everything works as intended except that when numbers are
entered that equal sum<=100, the "average" output is wrong. For example:
if I put in 8,10,19 and zero to exit the output is count 3 sum 37 average
9.25.... the average should be 12.3333. Now, if i enter in 8, 10, 99 the
output is count 3 sum 117 and average 39 which is correct. Why is it
working for sum>100 but not sum<=100??? I don't get it. What am I missing?

mac upgrading native php with homebrew, not getting it to work
mac upgrading native php with homebrew, not getting it to work
I tried to update the native php of my mba from 5.3.X to 5.4.X I did this:
brew tap homebrew/dupes brew tap josegonzalez/homebrew-php brew update
brew install php54
This installs php 5.4 on /usr/local/cellar/php54 now when doing which php,
it gives me /usr/bin/php
I tried to add this to ~/.bashrc : export PATH=/usr/local/cellar/php54:$PATH
Now when i re-open terminal and type which php it still tells me php is
located in /usr/bin/php
Is there a good way to fix this issue?

if (currentScale != initialScale) return;
if (currentPage > 1) {
--currentPage;
img.src = document.getElementById("page" + zeroPad(currentPage, 2) +
"url").value;
}
});
Is there anything I can do, code-wise, to capture these events in Android
4.2.2?
I have written a mobile web application that uses the JQuery mobile
swipeleft and swiperight events but these are not working on a Samsung
Galaxy S4 running Android 4.2.2. Running the web application in either the
standard web browser or in Chrome has the same issue: the swipe events are
not detected.
The following is how I am trying to detect the events which works fine in
other devices I have tested it on, even Android devices (but not Android
4.2.2):
$('#showImage').on("swipeleft", function (event) {
if (currentScale != initialScale) return;
if (currentPage < maxPage) {
++currentPage;
img.src = document.getElementById("page" + zeroPad(currentPage, 2) +
"url").value;
}
});
$('#showImage').on("swiperight", function (event) {
if (currentScale != initialScale) return;
if (currentPage > 1) {
--currentPage;
img.src = document.getElementById("page" + zeroPad(currentPage, 2) +
"url").value;
}
});

Encryption failed in Sipdroid Voip calls in android
Encryption failed in Sipdroid Voip calls in android
As I working on an app where I need to integrate VOIP calls in it.
After going through internet I found Sipdroid source code for free VoIP
calls & it is open source code too. As I integrated the following code it
is working good. But I want to encrypt and decrypt the data conversation
before sending and after receiving respectively. As I am not getting any
idea of integrating encryption and decryption in Sipdroid code, can anyone
help me with this. As I am struggling a lot with the following issue any
small help will me appreciated.

Rails 3, adding joins to default_scope for association of current_user
Rails 3, adding joins to default_scope for association of current_user
In my app i have a schema of Users and Tickets, each User can be
subscribed to many Tickets and viceversa.
For each ticket i fetch from the database, i want to display if
current_user is subscribed or not to the ticket itself.
An example of my query is as follows:
@tickets = current_user.tickets.limit(10).order('created_at DESC')
Can i do it using a default_scope with a join in Ticket model?, i need it
to return an additional field with a simple true or false, or nil.

.NET - high memory usage by clr.dll and native heaps
.NET - high memory usage by clr.dll and native heaps
I have been performing memory leak analysis using DebugDiag for a .NET
application which has shown continuous increase in memory.
After several test dumps and then capturing dumps over a day, I see that
the module clr.dll has 5.08 MB of allocations in first dump, 286.4 MB of
allocations in second and 609.56 MB in the third.
Specifically, the rise is in allocations caused by
clr!DoNDirectCall__PatchGetThreadCall+7b which has 894.33 KB allocation in
first, 280.85 MB in second and 601.13 MB in third. Here are some of the
call stacks from the third dump -

What could be causing this and how do I find out more about this ?
Also, my code uses the avaliable C# methods to run remote WMI queries and
retrieve that data.
In addition, my Native Heaps usage also increases. There are 40 native

increases. Its total usage goes from 67.57 MB to 1.59 GB to 3.82 GB. What
could be the cause of this, and is this related to clr's usage ?

Updating a .jar file that is in use
Updating a .jar file that is in use
I have a C# program that updates and then launches a Java application.
Before actually launching Java, it checks for updates to the .jar files
that program uses. It's possible that multiple people are running the
application on a given machine at one time (it could be a terminal server)
or that the same user is running multiple instances of the program. If
other people are running the application, the .jar file will be in use and
can't be updated. I'm trying to work around this.
My preference would be to rename the .jar file and update it. All the
people currently running the application can still use the renamed jar
file. Windows won't let you rename a file that's in use, either (though I
think Unix systems will).
I noticed that with Windows Explorer, though, you can copy/paste a jar
file and overwrite a .jar file that's in use. How does that work, and can
I somehow do something similar in my updater/launcher program?
Are there any other approaches I might use?
I have a C# program that updates and then launches a Java application.
Before actually launching Java, it checks for updates to the .jar files
that program uses. It's possible that multiple people are running the
application on a given machine at one time (it could be a terminal server)
or that the same user is running multiple instances of the program. If
other people are running the application, the .jar file will be in use and
can't be updated. I'm trying to work around this.
My preference would be to rename the .jar file and update it. All the
people currently running the application can still use the renamed jar
file. Windows won't let you rename a file that's in use, either (though I
think Unix systems will).

On the Github website they list what branches have been merged into
master. I would like to know how to list those branches through the Github

Youtube android player api getCurrentTimeMillis only updates every 1 second
Youtube android player api getCurrentTimeMillis only updates every 1 second
I'm using the Youtube player android api (latest version, fetched from
https://developers.google.com/youtube/android/player/). In my app I've
added a timer that calls the player's getCurrentTimeMillis method every
200 msec. The problem is that the method returns the same value for each
second that passes by. for example, I get the following output after the
running the app:
1877 1877 1877 1877 1877 2878 2878 2878 2878 2878 3879 3879 3879 3879 3879
4880 4880 4880 4880 4880 5881
As you can see, the time effectively updates every 1 second (5 timer
ticks). The same happens with a timer delay of 100 msec (every 10 ticks).
This of course, does not happen with the javascript api or the AS3 api.
Does anyone have any idea why it happens and how can I get a higher
resolution?
I tried the same app on the Nexus 7 and Galaxy Nexus (both running android
4.3) and got the same results.
Thanks in advance! Roy

Excel Date Format Change
Excel Date Format Change
I receive a CSV file from an external data source with the dates formatted
as shown below. I need to "convert" whatever is coming over into a date
that can be sorted properly. I've tried text to columns, formulas,
importing as text, etc but nothing will change this data into a usable
format. Each date comes over in one cell. I've had to clean data in the
past but the techniques used in the past are not working with this set. If
anyone has any ideas I would greatly appreciate the help. Thank you.

Remain status on checkbox, when refresh
Remain status on checkbox, when refresh
New to php, and sql. But here is the thing. I have a page that displays a
table from a database, based on certain criteria. The table is loaded
anytime I refresh the page. I am using this as a list of tasks for
service.
I'va added a column with checkboxes for service-personell to mark
everytime service has been done, ie. using this as a tasklist. But when u
refresh page, or close browser to visit the page again, the checkboxes are
listed as unchecked(of course)
I was just wondering how to maintain the status of checkboxes for a
certain time? Maybe cookies? If so I need some guidance.
My php
{foreach ($list as $key => $row)
{
echo '<tr class="xcrud-row-' . $i . '"><td class
="check_row"><div><input type="checkbox" name="status"
></div></td>';
if($this->is_numbers) echo '<td class="xcrud-num">' .
($key + $start + 1) . '</td>';}

The code is from quantitize.js. Thanks alot.
# has no method 'palette'"
I am learning to use the quantitize.js but getting the error "Uncaught
TypeError: Object # has no method 'palette'". I don't know what is wrong.
PLease help. Thanks.
