include google analytics in my js file
Would there be any drawbacks including the google analytics script in my
javascript file? Any suggestions?
HTML file:
<!DOCTYPE html>
<title>Include Analytics</title>
<script src=/js/myjsfile.js></script>
<p>No other Javascript in this document.
myjsfile.js:
window.onload = function(){
// my other functions
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new
Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-xxxxxxxx-x', 'domain.se');
ga('send', 'pageview');

how to upload multiple files in one
how to upload multiple files in one
I have made a code that let me upload multiple files but in separate
I was trying to upload a multiple files in one input where i set my input
tag into
<input type="file" multiple="" name="file1">
I selected 3 images but only 1 image was uploaded..
here is my VIEW before changing my input:
<?php echo form_open_multipart('test'); ?>
<p>
<?php echo form_label('File 1: ', 'file1') ?>
<input type='file' name='file1' id='file1'>
</p>
<p>
<?php //echo form_label('File 2: ', 'file2') ?>
<input type='file' name='file2' id='file2'>
</p>
<p><?php echo form_submit('submit', 'Upload them files!') ?></p>
and here is my CONTROLLER
function index()
{
if (isset($_POST['submit']))
{
$this->load->library('upload');
$config['upload_path'] = './upload_documents/';
$config['allowed_types'] = 'jpg|png|gif|jpeg|JPG|PNG|GIF|JPEG';
$config['max_size'] = '0'; // 0 = no file size limit
$config['max_width'] = '0';
$config['max_height'] = '0';
$config['overwrite'] = TRUE;
$this->upload->initialize($config);
foreach($_FILES as $field => $file)
{
// No problems with the file
if($file['error'] == 0)
{
// So lets upload
if ($this->upload->do_upload($field))
{
$data = $this->upload->data();
//alert("nice");
}
else
{
$errors = $this->upload->display_errors();
die();
}
}
else{
echo "alksjdfl";
die();
}
}

Probability - exactly one of A and B occurs
Probability - exactly one of A and B occurs
A and B are events that are subsets of the sample space. C is the event
that exactly one of A and B occurs.
1) Write an expression for C in terms of unions, intersections and
complements involving the events A and B
2) Let P be a probability defined on the events of the sample space. Write
an expression for P(C) in terms of P(A), P(B) and P(A¿B). Give proof of
your result.
Would I be right in saying that 1) is just
C=(AUB)-(A¿B)
Or would it be? (A¿B^c)U(A^c ¿B)

I have problem with pack function, when using Card Layout. I created 1
JFrame which include JPanel(in cardlayout) and this JPanel contains two
JPanels. ... so when I run my program the windows is resized to biggest
JPanel in program and i cant dynamicly resize it.
now screens: my background1(smaller background) class when i run program
only with this panel has width like 200 http://i41.tinypic.com/scfi88.jpg
when i run my program with added background2 the background gets width of
it so it looks for like 400 http://i41.tinypic.com/2lu742x.jpg so it gets
width of my background2 panel
code: main class:
public class main extends javax.swing.JFrame {
private JPanel mainPanel;

mainPanel.add(card1,"card1");
mainPanel.add(card2,"card2");
CardLayout cl = (CardLayout) (mainPanel.getLayout());
cl.show(mainPanel, "card1");
mainPanel.revalidate();
mainPanel.repaint();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
}
public static void main(String args[]) {

How can I implement tf history command in C#?
How can I implement tf history command in C#?
I would like to implement the following command using TFS programming API:
tf history /stopafter:1 /version:W /recursive /format:detailed /noprompt .
I have some code, but it tries to inspect local workspace info and there
is none. So, I am back to nothing.
How is it done?

How do I calculate roll, pitch, yaw from a unit vector?
How do I calculate roll, pitch, yaw from a unit vector?
I am provided a unit vector giving a direction in x, y, z coordinates, and
that the roll is defined as about the x axis, pitch around y, yaw around
z. I'm trying to determine how to calculate roll, pitch, and yaw given the
unit vector. I can see that the information should be there, but after
looking in to it for a bit, I've been unable to find the correct method of
doing this. How do I go about doing this?

My company is getting spammed by itself, or rather by it's Qmail, we've
got a few automated processes sending out e-mails with Qmail and Zend
Mail.
I'm not a expert in either of these, (I know literally nothing about
them), and the 'spam e-mails' are Qmail telling us that a series of

Is there a way for me to locate what is generating these error e-mails? Or

how to insert a piece of text in all headers in a document with VBA
how to insert a piece of text in all headers in a document with VBA
all the answers I can find (and all the examples elsewhere on the web) are
about very complicated insert operations (only on 1 header, or only odd
pages, or not using select, or some such). How do you insert a simple
piece of text into all headers in a word document using VBA? Thanks.

I'd like to know how would i generate a template with Java using Apache

details of n students by plugging in each student info into those place
holders. Please read carefully I do not want to create pdf's using a
template created outside, no, I want to create the template itself using
Java then use the template again in Java. thanks.

Merge Sort in place for python (Cant find what is wrong)
Merge Sort in place for python (Cant find what is wrong)
I was reading about merge sort(In place) in my algorithm book (Intro to
algorithms 3rd edition Cormen), and I decided to implement it in Python.
The problem is that I can't find what I am doing wrong... I saw some code
in C++, but even with that I can't fix it.
Here is my code:
def MERGE(A,start,mid,end):
L=[0]*(mid - start + 1)
for i in range(len(L) - 1):
L[i] = A[start+i]
L[len(L) - 1] = 100000 # centinel, (fix)
R=[0]*(end - mid + 2)
for j in range(len(R) - 1):
R[j] = A[mid+j]
R[len(R) - 1] = 100000
i = 0
j = 0
k = start
for l in range(k,end):
if(L[i] < R[j]):
A[l] = L[i]
i = i + 1
else:
A[k] = R[j]
j = j + 1
def mergeSort(A,p,r):
if p < r:
mid = int((p+r)/2)
mergeSort(A,p,mid)
mergeSort(A,mid+1,r)
MERGE(A,p,mid,r)
A = [20, 30, 15, 21, 42, 45, 31, 0, 9]
mergeSort(A,0,len(A)]
When I run the code I have some index problems:
File "myrealmerge.py", line 9, in MERGE
R[j] = A[mid+j]
IndexError: list index out of range
I know that this my be a "dumb question" and that there is some related
post, but I tried the suggestions in there and It does not work for me...
Can anyone help me? T Thanks!

How do I access the command line argument variable when making an alias in Terminal?
How do I access the command line argument variable when making an alias in
Terminal?
I'm making a few aliases to speed up my development processes.
Right now I'm trying to make a cdls which is quite obviously a cd
{arbitrary-file} && ls {arbitrary-file}
I was under the impression that alias cdls='cd $@ && ls $@ would work, but
it looks like I was mistaken about $@ carrying the argument (file path)
since this sends me back to my $HOME directory every time.

MATLAB GUI Zoom with multiple plots
MATLAB GUI Zoom with multiple plots
I have 2 plots in a MATLAB gui and i want to link them together so a zoom
on one plot zooms the other.
Unlike similar questions i have seen on linking plots neither my x data or
y data is shared by either graph, but it is related.
My data consists of the heights of land measured by a plane flying over
them over a period of 5 seconds.
Plot 1 : The height of land
y: height = [10,9,4,6,3];
x: time = [1,2,3,4,5];
Plot 2 : land coordinates
y: latitude = [10,20,30,40,50];
x: longitude = [1,2,3,4,5];
If the user zooms in the x axis on Plot 1, for example showing the first 3
seconds of flight I want to zoom the x and y-axis of Plot 2 so only the
first 3 longitude & latitude coordinates in the longitude & latitude
arrays are shown.
Is this possible?

The problem with this, when, in browser I use "view page source" I see the

CLR Hosting in C++ : how to use Type.InvokeMember with out Parameter
CLR Hosting in C++ : how to use Type.InvokeMember with out Parameter
I'm doing some work with CLR Hosting (with C++). I followed the sample
that microsoft provided and I can load .net runtime and load assemblies,
create some object instance and so on.
Now I have a question about using _Type.InvokeMember.
virtual HRESULT __stdcall InvokeMember (
/*[in]*/ BSTR name,
/*[in]*/ enum BindingFlags invokeAttr,
/*[in]*/ struct _Binder * Binder,
/*[in]*/ VARIANT Target,
/*[in]*/ SAFEARRAY * args,
/*[in]*/ SAFEARRAY * modifiers,
/*[in]*/ struct _CultureInfo * culture,
/*[in]*/ SAFEARRAY * namedParameters,
/*[out,retval]*/ VARIANT * pRetVal ) = 0;
I can use other overload version of it to invoke the object method
successfully. However, now I want to invoke a method with a out/ref
parameter like:
double TestOutParam(out double output);
The tricky part is the modifiers. I've tried passing a boolean array or
even creating a dotnet ParameterModifier to fill with it. All I get is
0x80131533. COR_E_SAFEARRAYTYPEMISMATCH.
Here is my sample code:
CComSafeArray<VARIANT> parameters; //The InvokeMember Args Array
parameters.Create(2L,0L);
parameters.SetAt(0,_variant_t(input)); //The first parameter
double dbResult=0;
_variant_t outParam,vtOutput;
outParam.vt= VT_R8;
outParam.dblVal=0;
parameters.SetAt(1,outParam,0);//The second parameter
CComSafeArray<VARIANT> parameterMods; //The ParameterModifier Array
parameterMods.Create(1L,0L);
auto parameterModifier=DotNetParameterModifier::Create(2); //Create a
dotnet ParameterModifier
parameterModifier->SetItem(0,false);
parameterModifier->SetItem(1,true);//Set 2nd item to true, means the 2nd
parameter is out parameter
parameterMods.SetAt(0,parameterModifier->GetVtObject(),0);//GetVtObject
return the VARIANT point the ParameterModifier
/*A wrapper of the _type.InvokeMember. The actual code is
HRESULT hr = _typePtr->InvokeMember(bstrMethodName,
static_cast<BindingFlags>(
BindingFlags_InvokeMethod | BindingFlags_Instance | BindingFlags_Public),
NULL, vtObject,parameters, parameterModifier,NULL,NULL,&vtRetValue);
*/
_variant_t
boolResult=this->InvokeMember("TestOutParam",parameters,parameterMods);
parameterMods.Destroy();
parameters.Destroy();
if(boolResult.boolVal)
return outParam.dblVal;
return 0;

Getting started with ARM or STM microcontrollers
Getting started with ARM or STM microcontrollers
I'm not too good with all this microcontrollers stuff.
I've used to handle with AVR assembler. But i'd like to get some knowledge
on ARM (or specific for STM MCUs) assembler and C.
Is there any book like 'quick guide' to ARM (or STM specific) assembler?
Thanks in advance.
Sorry for my broken English.

Reorder table from jqueryUI sortable array
Reorder table from jqueryUI sortable array
Hello thanks for taking a look at this.
I am using jquery ui sortable on an <ul> whose id's increment from 0 - 16.
It creates an array like this when you sort.
var arr = ["1", "2", "4", "5", "6", "3", "10", "7", "8", "9", "17", "11",
"12", "13", "14", "15", "16"]
I have a method that I pass the list into to. Currently im trying to just
move the row to the new position, but I might have to repaint the table.
Here's the method.
positionColumns: function(list) {
var _this = this;
if (!list) list = this.order;
$(list).each(function(i, val) {
if (parseInt(val, 10) !== _this.order[i]) {
work(val, _this.order[i]);
console.log(list);
console.log(_this.order[i]);
} else {
return;
}
});
function work(from, to) {
var table = $('#dealbook-table');
var rows = $('tr', table);
var cols;
rows.each(function(i, row) {
cols = $(row).children('th, td');
console.log(cols);
cols.eq(from).detach().insertBefore(cols.eq(to));
});
}
},
Any help would be appreciated.

What is the difference between the org.junit package and the junit.framework package?
What is the difference between the org.junit package and the
junit.framework package?
Whenever I use a Junit assert in my code, my IDE (Intellij IDEA 12)
politely offers to static-import it for me:
import static junit.framework.Assert.assertTrue;
However, it always gives me the choice of importing either the "org.junit"
version or the "junit.framework" version:
import static org.junit.Assert.assertTrue;
I can't find a clear answer online about what the difference is between
these two packages - is there a difference? If so, what is it? They both
come out of exactly the same Junit4 jar, so what's going on?

jQuery input selection - adding up totals inside a repeater
jQuery input selection - adding up totals inside a repeater
have two textboxes defined like so, which are inside a repeater:
<asp:TextBox ID="txtHours" runat="server" CssClass="text misch"
Width="50px" Text='<%# Eval("laborHours") %>'/>
<asp:TextBox ID="txtCosts" runat="server" CssClass="text misc"
Width="50px" Text='<%# Eval("totalCosts") %>'/>
i also have two boxes where i want to put totals:
<asp:TextBox ID="txtMiscH" runat="server" CssClass="text hours"
Width="200px" />
<asp:TextBox ID="txtMisc" runat="server" CssClass="text add" Width="200px" />
when the value in the repeater changes, i want to add them up and put in
the appropriate total boxes.
this is where i am now:
//add up miscaleneous mnumbers
//dollar amoungs
$("input[class~='misc']").change(function (event) {
var sum = 0;
var num = 0;
alert("X");
$("input[class~='misc']").each(function (event) {
alert("X");
num = parseInt($(this).val()) || 0;
sum = sum + num;
});
$("input[id*='txtMisc']").val(sum);
$("input[class~='add']").trigger('change');
});
//hours
$("input[class~='misch']").change(function (event) {
var sum = 0;
var num = 0;
$("input[class~='misch']").each(function (event) {
num = parseInt($(this).val()) || 0;
sum = sum + num;
});
$("input[id*='txtMiscH']").val(sum);
});
but it does not look like the first option works at all.
also i saw that there are different ways to select input
input[class~ or input[class* or input[class^
am i using the wrong one?
i guess because misc is also part of misch, it does the calculations for
hours, even when i only update the misc costs box. please hep. would
renaming class type be the easiest way to fix this?

Creating lists from subtrees
Creating lists from subtrees
For an application I'm writing, I need to create flat lists from a tree
based structure which contain the items of the sublist.
For example, if I had this tree:
-a
|-b
|-c
|-d
I'd like to create lists from the left and right leaves recursively, so
for example:
[a][b,c,d]. [b][c,d], [c][d]
etc
So far I'm storing my tree as a tuple like so:
(1.0,(0.5,(0.25, (0.125,'d'),(0.125,'c')),(0.25,'b')),(0.5,'a'))
I have a function which prints the information on the leaves:
def printTree(tree, prefix = ''):
if len(tree) == 2:
print tree[1], prefix
else:
printTree(tree[1], prefix + '0')
printTree(tree[2], prefix + '1')
(This is a Huffman).
I've tried creating a function whoneich replaces the print statements with
list() statements, but that didn't work.
Does anyone have any ideas about how I could go about this?

FPDF Footer on last page using {nb}
FPDF Footer on last page using {nb}
I have seen quite a few questions on this but not definitive answer. Im
using FPDF to dynamically create PDF with values form a DB, I only want a
footer on the last page, seeing as its values are based on DB values the
PDF could be 2,3,4 pages long. So i started messing around with the
footter of FPDF like so
function Footer()
{
$this->SetY(-15);
$this->SetFont('Arial','I',8);
//Page number
$pagenumber = '{nb}';
if($this->PageNo() == 2){
$this->Cell(173,10, ' FOOTER TEST - '.$pagenumber, 0, 0);
}
}
This retruns the value "FOOTER TEST - 2" on the second page and if i set
the if to "<=2" will put the same on page one and two, GREAT! it
recognises $pagenumber as 2 or if i had 3 pages as 3, so it can see that i
have however many pages, however, when i change the code to:
function Footer()
{
$this->SetY(-15);
$this->SetFont('Arial','I',8);
//Page number
$pagenumber = '{nb}';
if($this->PageNo() == $pagenumber){
$this->Cell(173,10, ' FOOTER TEST - '.$pagenumber, 0, 0);
}
}
Thinking that it output the last page once, adding that to the if
statement will make it work, it doesn't display anything, like the if
statement cant recognize the value for $pagenumber, is this because it is
a string or int trying to compare to the opposite or something else?
Any help greatly appropriated.

When should bug fixing and end to end testing happen in a Sprint?
When should bug fixing and end to end testing happen in a Sprint?
Our sprint duration is 2 weeks during which we develop some features and
test them by developers. then we release the product to the end to end
testing team and the sprint ends. The testing team will test and report
back to us for bug fixing after our sprint has ended in their own sprint.
One idea is that when a sprint ends we should have a bug-free and
deliverable product. This means that we should be changing our sprint
duration to 3 weeks and spend the last week for testing and bug fixing so
that we're sure that end of sprint means a deliverable product.
But that's not realistic, we don't know how long testing takes.

How do I invoke a method that takes a "Collection
How do I invoke a method that takes a "Collection
The method signature looks like this:
public void addThemAll(Collection<? extends T> c)
Which essentially just adds every element of the collection to my
LinkedList. But I keep trying to feed this method an Array or a Linked
List and I always get an error. For example:
double[] myarray = new double[]{3.4, 4.5, 8.6};
mylist.addThemAll(myarray);
I'm sure this is something straightforward, but I can't find an example
online that just passes an array/linked list into a method like this.

I have tested http://www.phash.org/demo/ . There are three algorithms it

DCT suggests 1-2 as similar. But it doesn't find 1-4 as similar.
Can you suggest different libs, algorithms especially to find 1-4 as
similar? As I said before my aim is to find (1,2,3,4) as similar and

Do I must need to dispose FileStream object
Do I must need to dispose FileStream object
I am pretty depressed by my programming knowledge but do we really need to
dispose FileStream Object ?
Reason I am asking is because code is throwing "File being used by another
process" exception once in 100 cases and for a moment as if i try again(to
download file using file stream) it works fine.
Please refer to this question for code.
Since it only happening once in 100 or so making me so confused and it's
happening on production server so can't debug at all, but works perfectly
on my development machine...

TCPDF writeHTML()
TCPDF writeHTML()
I am working on two column layout input comes from an editor which has
images and text. Images can come as one column or full width. Everything
works fine when I insert images in one column. But when I insert image as
2 column it fits perfectly in the column but the text after that is
somewhat not aligned.
Text covers the after space correctly but when it goes to second column
some space from the top till where the image ends on the first column is
blank and starts after that.
if ($this->myResetColumn) {
$this->resetColumns();
$this->setEqualColumns($this->myCols, $this->myWidth);
$this->setXY($this->GetX(), $this->GetY());
$this->selectColumn();
}
$this->writeHTML($content, true, false, true, false, $align);
Second Question
It there a way, I can make few checks while the writeHTML() function is
executing or I have to change the function itself, which will not be a
good idea to change the source code. For AddPage, I override it, after the
line at the end like this
$this->startPage($orientation, $format, $tocpage);
if (condition) {
// some function call
}
but writeHTML() is a lengthy function to override and it will lose many
options it has.
I am working on two column layout input comes from an editor which has
images and text. Images can come as one column or full width. Everything
works fine when I insert images in one column. But when I insert image as
2 column it fits perfectly in the column but the text after that is
somewhat not aligned.
Text covers the after space correctly but when it goes to second column
some space from the top till where the image ends on the first column is
blank and starts after that.
if ($this->myResetColumn) {
$this->resetColumns();
$this->setEqualColumns($this->myCols, $this->myWidth);
$this->setXY($this->GetX(), $this->GetY());
$this->selectColumn();
}
$this->writeHTML($content, true, false, true, false, $align);
Second Question
It there a way, I can make few checks while the writeHTML() function is
executing or I have to change the function itself, which will not be a
good idea to change the source code. For AddPage, I override it, after the
line at the end like this
$this->startPage($orientation, $format, $tocpage);

}

Mysql query with if exists check in where clause
Mysql query with if exists check in where clause
I have two tables (A and B) where my query compares a calculation from
table A with a range in table B and then insert a corresponding value to
the range(also in table B) in the third table(table C) based on dates.
However,it is a possibility that table A may not have data for everyday
and for those days i want to enter the value against the second lowest
range.
I am looking for a way to embed IF EXISTS in the WHERE clause something
like this:
SELECT B.value from TableB B INNER JOIN TableA A ON A.id=B.id WHERE B.id=4
and (IF DATA EXISTS) B.v1+B.v2 between A.min and A.max (ELSE Choose the
second lowest A.min)
The query above is an example to explain what i am trying to do, hence, it
is not a valid query. I do not want to use a subquery for obvious
performance issues.
I will appreciate any help.Thanks in advance :)

C++ memory leaks with unordered_map
C++ memory leaks with unordered_map
I've discovered that I have a memory leak somewhere in my application but
I've been having trouble narrowing it down. I've tried using the function
_CrtDumpMemoryLeaks as instructed in this example but it doesn't show file
names. So, I've been trying to find the first point of memory leaks (as
there seem to be quite a few according to the output) by placing calls to
this dump function at various points. It seems that I am getting a lot of
them straight away very early in my constructors for objects.
Upon further investigation, I seem to be getting them with definitions for
std::unordered_map even to the point where having a simple main function
that just declares a local variable has a memory leak.
For example the following code produces a memory leaks:
void main()
{
_CrtDumpMemoryLeaks(); // executing this line, no memeory leaks found
std::unordered_map<int, int> intMap;
_CrtDumpMemoryLeaks(); // executing this line, memeory leaks found
}
I'm completely confused at this point and get the feeling that chasing
this is not going to help me find the memory leak that I am originally
noticed.
Any help is very much appreciated.

Complex number equals method
Complex number equals method
I'm making a complex number class in Java like this:
public class Complex {
public final double real, imag;
public Complex(double real, double imag) {
this.real = real;
this.imag = imag;
}
... methods for arithmetic follow ...
}
I implemented the equals method like this:
@Override
public boolean equals(Object obj) {
if (obj instanceof Complex) {
Complex other = (Complex)obj;
return (
this.real == other.real &&
this.imag == other.imag
);
}
return false;
}
But if you override equals, you're supposed to override hashCode too. One
of the rules is:
If two objects are equal according to the equals(Object) method, then
calling the hashCode method on each of the two objects must produce the
same integer result.
Comparing floats and doubles with == does a numeric comparison, so +0.0 ==
-0.0 and NaN values are inequal to everything including themselves. So I
tried implementing the hashCode method to match the equals method like
this:
@Override
public int hashCode() {
long real = Double.doubleToLongBits(this.real); // harmonize NaN bit
patterns
long imag = Double.doubleToLongBits(this.imag);
if (real == 1L << 63) real = 0; // convert -0.0 to +0.0
if (imag == 1L << 63) imag = 0;
long h = real ^ imag;
return (int)h ^ (int)(h >>> 32);
}
But then I realized that this would work strangely in a hash map if either
field is NaN, because this.equals(this) will always be false, but maybe
that's not incorrect. On the other hand, I could do what Double and Float
do, where the equals methods compare +0.0 != -0.0, but still harmonize the
different NaN bit patterns, and let NaN == NaN, so then I get:
@Override
public boolean equals(Object obj) {
if (obj instanceof Complex) {
Complex other = (Complex)obj;
return (
Double.doubleToLongBits(this.real) ==
Double.doubleToLongBits(other.real) &&
Double.doubleToLongBits(this.imag) ==
Double.doubleToLongBits(other.imag)
);
}
return false;
}
@Override
public int hashCode() {
long h = (
Double.doubleToLongBits(real) +
Double.doubleToLongBits(imag)
);
return (int)h ^ (int)(h >>> 32);
}
But if I do that then my complex numbers don't behave like real numbers,
where +0.0 == -0.0. But I don't really need to put my Complex numbers in
hash maps anyway -- I just want to do the right thing, follow best
practices, etc. And now I'm just confused. Can anyone advise me on the
best way to proceed?

First, I just want to say I recently started with programming, so I'm not
very good. This is my problem:
x = int(input("Write a number between 1-100: "))
while x > 100:
x = int(input("The number must be less than 101: "))
while x < 1:
x = int(input("The number must be higher than 0: "))
else:
print ("The number is:",x)
There's a way to cheat the code by doing this:
Write a number between 1-100: 101
The number must be less than 101: 0
The number must be higher than 0: 101
The number is: 101
I basically don't want the user to be able to write a number higher than
100 or lower than 1.
I'm sorry for the bad explanation but I tried my best and, one again, i

How can I use Twitter Bootstrap Dropdowns to include the first item as a toggle?
How can I use Twitter Bootstrap Dropdowns to include the first item as a
toggle?
Twitter Bootstrap Dropdowns Docs show the following syntax for a dropdown:
<div class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown
trigger</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
<li role="presentation"><a role="menuitem" tabindex="-1"
href="#">Menu Item 1</a></li>
...
</ul>
</div>
But instead I'd like the first item (Drowdown trigger above) to be
included in the menu items.
Can you suggest a strategy to trigger a dropdown menu from a list
including all items?
Here's an example HTML format of what I'm after.
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
<li role="presentation"><a class="dropdown-toggle btn"
data-toggle="dropdown" href="#">General Support <b
class="caret"></b></a></li>
<li role="presentation"><a role="menuitem" tabindex="-1"
href="#">Sales</a></li>
<li role="presentation"><a role="menuitem" tabindex="-1"
href="#">Accounting</a></li>
</ul>
My actual use case is a little more complex and is the reason I can't
simply use an HTML select input.

how to add where clause in formtype symfony2
how to add where clause in formtype symfony2
its been days now that am looking for the 'how' of this problem. I just
learned symfony2 and i cant find a way to this, i've tried different stuff
found on the net but i could not get any to work.
Here is my problem, I have a form PictureType in which i include another
entity Collection (which is a collection of picture or if you prefer an
album of picture).
When the user uploads his picture he needs to select in which album he
wants to put it.
My problem is that I cant figure out how to tell in my PictureType to
select ONLY the collections of the current user.
here is my pictureType
$builder
->add('file')
->add('collection', 'entity', array(
'class' => 'AppPictureBundle:Collection',
'property' => 'name'
));
I want to insert after property something like this
Where 'user_id' = $this->getUser()
I have a manyToOne on Collection target User and a ManyToOne on picture
target collection.

How to setup context sharing between GPUImage and cocos2d to capture gameplay video
How to setup context sharing between GPUImage and cocos2d to capture
gameplay video
I'd like to capture video from cocos2d gameplay in my app. I can just
simply use glReadPixels, but it's very slow. I found out that
GPUImage/GPUImageMovieWriter uses more advanced approach, but I have to
setup context sharing between GPUImage and cocos2d
Anybody knows how to make that?
I've tried to push GPUImage's sharegroup into cocos2d, but I have no luck:
container = [CCGLView viewWithFrame:CGRectMake(116, 37, 480, 640)
pixelFormat:kEAGLColorFormatRGB565 depthFormat:0 preserveBackbuffer:NO
sharegroup:[[[GPUImageContext sharedImageProcessingContext] context]
sharegroup] multiSampling:NO numberOfSamples:0];
Any help would be appreciated.

Named arguments call in C# with variable parameter number
Named arguments call in C# with variable parameter number
Suppose I have the following C# function:
void Foo(int bar, params string[] parpar) { }
I want to call this function using named arguments:
Foo(bar: 5, parpar: "a", "b", "c");
The compiler gives error message: "Named arguments cannot precede
positional" since I have no name before "b" and "c".
Is there any way to use named arguments without manually representing
params as an array?

parsing success callbacks from ajax call
parsing success callbacks from ajax call
I have a backbone object that I'm calling save on. How do I know what
comes back in the ajax call. Looking at the code for the project I got put
on, I see some people just have a generic
success: function (data) {
console.log(data);
Then other times, I see:
success: function (library, response) {
console.log(library);
console.log(response)
I'm confused on how you would know you would have I presume a library or
response object, vs a general data. When I look at the second example, I
am looking at the output of
console.log(response);
and I see response has three attributes:
Notifications
Response
ResponseStatus
Response itself looks like Object {Id="12345", href="the/href", Name="asdf"}
So it looks like a Javascript object to me, but then when I try to do
console.log(response.Name);
I always get undefined even though I can see the value.
So I'm trying to understand how the callback in an ajax calls. Like when
you can use an actual library object, response object, vs a data object,
and how I can go about parsing the results properly. Thanks in advance!

simple Ruby Input and Output Exercise log
simple Ruby Input and Output Exercise log
I have a project in my programming class. This is my assignment: Create a
program that allows the user to input how many hours they exercised for
today. Then the program should output the total of how many hours they
have exercised for all time. To allow the program to persist beyond the
first run the total exercise time will need to be written and retrieved
from a file.
This is the code I have so far:
File.open("exercise.txt", "r") do |fi|
file_content = fi.read
puts "This is an exercise log. It keeps track of the number hours of
exercise. Please enter the number of hours you exercised.
hours = gets.chomp.to_f
end
output = File.open( "exercise.txt", "w" )
output << hours
output.close
end
What else to do I have to add?

T-SQL Creating Dynamic Tables and Populating
T-SQL Creating Dynamic Tables and Populating
Im fairly new to T-SQL and could use some help with a Script I am writing.
The purpose of the script is to create dynamic tables and populate them
with related data. Currently Im getting a vague error which Im guessing is
caused because Im missing some syntax. The script is below. The idea is
that I will run the script one time to create and load these tables. This
process is part of a data migration project. Here's the error Im receiving
when I "Execute" the script. Any tips or suggestions are appreciated.
Thanks ahead of time.

Im fairly new to T-SQL and could use some help with a Script I am writing.
The purpose of the script is to create dynamic tables and populate them
with related data. Currently Im getting a vague error which Im guessing is
caused because Im missing some syntax. The script is below. The idea is
that I will run the script one time to create and load these tables. This
process is part of a data migration project. Here's the error Im receiving
when I "Execute" the script. Any tips or suggestions are appreciated.
Thanks ahead of time.

Is it safe to return a VLA?
Is it safe to return a VLA?
The following code uses the heap:
char* getResult(int length) {
char* result = new char[length];
// Fill result...
return result;
}
int main(void) {
char* result = getResult(100);
// Do something...
delete result;
}
So result has to be deleted somewhere, preferably by the owner.
The code below, from what I understand, use an extension called VLA, which
is part of C99, and not part of the C++ standard (but supported by GCC,
and other compilers):
char* getResult(int length) {
char result[length];
// Fill result...
return result;
}
int main(void) {
char* result = getResult(100);
// Do something...
}
Am I correct in assuming that result is still allocated on the stack in
this case?
Is result a copy, or is it a reference to garbage memory? Is the above
code safe?

C++ Fix for checking if input is an integer
C++ Fix for checking if input is an integer
for example, if I enter "2a", it does not show an error nor asks the user
to re-input the value. how do i fix this?
while (std::cin.fail())
{
std::cout << "ERROR, enter a number" << std::endl;
std::cin.clear();
std::cin.ignore(256,'\n');
std::cin >> dblMarkOne;
}
std::cout << "" << std::endl;
