Cakephp get data from another model

Cakephp get data from another model

I'm developing an e-commerce website. I have 2 tables - Customers & Shipping
Field in Customers - id, name, address, city, postal & country Field in
Shipping - id, address, city, postal & country
The process flow, after the customer click checkout button, they need to
fill up shipping form (shipping - add.ctp).
But in add.ctp, i also want to show address from table customer. So, I can
put check button - Use this address as shipping address.
Anyone can help how the controller & add.ctp looks like? Thank You.

Find maximum value of a continuous function at a specific resolution

Find maximum value of a continuous function at a specific resolution

Imagine having a function that is continuous over a range [0.0,n]. Are
there any algorithms to find the maximum value of the function given a
minimum step size s more quickly than simple iteration? The simple
iteration is straightforward to program but the time complexity grows when
n / s is large.
double maxValue = 0;
double maxValueX = 0;
double s = 0.1 * n;
for (double x = 0.0; x <= n; x += s)
{
double value = someFunction(x);
if(value > maxValue) {
maxValue = value;
maxValueX = x;
}
}
I have tried this approach which is much quicker, but don't know if it
will get stuck on local maximums.
double min = 0;
double max = n;
int steps = 10;
increment = (max - min) / steps;
while (increment > s)
{
double maxValue = 0;
double maxValueX = X;
for (double x= min; x <= max; x+= increment)
{
double value = someFunction(x);
if(value > maxValue) {
maxValue = value;
maxValueX = x;
}
}
min = Math.Max(maxValueX - increment, 0.0);
max = Math.Min(maxValueX + increment, n);
increment = (max - min) / steps;
}

How to identify unbound variables for auto-including of modules using Template Haskell?

How to identify unbound variables for auto-including of modules using
Template Haskell?

Is it possible to use Template Haskell to pre-analyze a code, searching
for undefined symbols and including them, if they are defined elsewhere?
I.E, simulating Eclipse's auto-include for Java programs (except not
actually altering the source)?

alpha blending in opengl es not working

alpha blending in opengl es not working

I'm trying to vary the transparency of a texture drawn onto a quad, the
code below works fine except the alpha set with glColor4f has no effect.
What are the possible reasons for this? Is it likely to be a gl setting
somewhere else in the program?

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_COLOR, GL_ONE_MINUS_SRC_ALPHA);
glActiveTexture(GL_TEXTURE0);
glBindTexture(GL_TEXTURE_2D, textureId);
glColor4f(1.0f, 1.0f, 1.0f, 0.3f);
glVertexAttribPointer(vertexHandle, 3, GL_FLOAT, GL_FALSE, 0, quadVertices);
glVertexAttribPointer(normalHandle, 3, GL_FLOAT, GL_FALSE, 0, quadNormals);
glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0,
quadTexCoords);
glEnableVertexAttribArray(vertexHandle);
glEnableVertexAttribArray(normalHandle);
glEnableVertexAttribArray(textureCoordHandle);
glUniformMatrix4fv(mvpMatrixHandle, 1, GL_FALSE,
(GLfloat*)&modelViewProjectionButton.data[0] );

glDisableVertexAttribArray(vertexHandle);
glDisableVertexAttribArray(normalHandle);
glDisableVertexAttribArray(textureCoordHandle);

Visual Studio Toolbox - close toolbox

Visual Studio Toolbox - close toolbox

I wonder if ther is a way of confirming selection of a tool from MS VS
Toolbox / close toolbox. The opposite of:
ctrl+w .. ctrl+x
and
ctrl + alt + x
What I find really annoying is when I have to add an association between
two entities in model designer, and the one that I want to start with is
hidden behind toolbox.
If so, I have to use e.g. scrollbar to make toolbox loose focus.
Is there a way to confirm that I want to use selected control and hide the
toolbox?
(like shift+esc in VS6) ?

Import updating CSV into SQL Server

Import updating CSV into SQL Server

I'm looking for a simple solution (beginner to SQL) to allow the import of
data from my .csv file to my SQL DB.
I have a third party program that is updating my .csv file every 30
seconds and I want to put that updating information into my SQL DB. I
tried the importing & exporting wizard but it didn't work due to the .csv
file being utilized by the other third party program.
Getting the information into the SQL DB doesn't need to be in real time it
could just retrieve all the information when opening a saved sql query
file.
Thank you!

is my working correct? Vector equations and planes.

is my working correct? Vector equations and planes.

Is my working correct with regards to the following question? Any feedback
is appreciated.
Question: Find a vector equation for the plane that passes through the
points $A(1, 1,a),B(2, 0,&#8722;1)$ and $C(&#8722;2, 1,&#8722;1)$. If a
has the value $&#8722;1$, what can you say about the plane?
Is my working correct?
Vector $BA = <-1 , 1, 1+a>$ and vector $CA=<3, 0, 1+a>$
A normal vector to the plane $ABC$ is the vector product
$$n=BA x CA =<1+a, 4(1+a), - 3> $$
A vector equation for the plane is
$$r.n = (2,0,-1).(1+a, 4(1+a), -3) =5+2a$$
If $a=-1$ the plane has equation $r.(0,0,-3) = 3$
which has Cartesian equation $z=-1$ and this is a plane parallel to the
$x-y$ plane.

Derivatives and tangent to the line of a curve

Derivatives and tangent to the line of a curve

Find the equations of all tangent lines to the curve y=x/(x+1) that
intersect the point (1,2). Note that the point (1,2) does not lie on the
curve. Please simplify your final answer as much as possible.
This is what I have done so far. I don't know if it is correct.
1/(x+1)= -x-2/(x-1) [cross-multiplied] to get, x-1=-x^2 -3x -2
I made it equal to zero to get a quadratic equation of x^2 + 4x + 1 = 0 to
solve for x I got x = -2 +- root 3
I dont know what to do next.

jQuery Waypoint: FadeIn - FadeOut effect on scroll

jQuery Waypoint: FadeIn - FadeOut effect on scroll

I'm trying to create a fadeIn and fadeOut effect with elements on scroll.
I'm told this can be done with WayPoint. I've tried a variety of things,
but nothing seems to work, no fade in, no fade out, and no errors in the
console. Here is what I'm currently using:
<script type='text/javascript'>
$(window).load(function(){
$("#top-section").waypoint(function(){
$(this).fadeIn('slow');
},{
offset: 'bottom-in-view'
});
$(this).fadeOut('slow');
},{
offset: 'top-in-view'
});
});
</script>

Pass a generic Object to a list in a method - JAVA

Pass a generic Object to a list in a method - JAVA

I've two question, They may be silly questions but it got me confused now.
QUESTION 1:
I've this code:
private List<Car> carList;
public void setData(List<Object> list)
{
this.carListist = list;
}
But on this.carList = list I get a compiling error: incompatible types,
required: List<Car> but found List<Object>
My question is, why this error? Isn't List a list of objects type Car? So
why doesn't it accept an Object there?
QUESTION 2: I change the above code to the following and the error goes away:
private List<Object> carList;
public void setData(List<Object> list)
{
this.carListist = list;
}
public Object getValueAt(int row, int column) {
Car car = carList.get(row); //Compiling error here
switch(column)
{
(...)
}
(..)
Ther compiling error (signed in the code comment) is incompatible types,
required Car but found Object What I don't understand is, now list is
defined as an object list. Car is an object. Why car, as being an object,
is not accepted?
Anyway to fix this for both question 1 and 2?

Control RTMP chunk size - AWS Cloudfront

Control RTMP chunk size - AWS Cloudfront

I am developing a website where I am using flow player flash as my video
player. I am using AWS(EC2 + S3 + Cloudfront) to manage and store my
files. Using cloudfront RTMP I have setup my video streaming.
But the streaming is bit slow, like the buffer takes too long to play
small size of video, I have tested my internet speed, and rather then my
website other websites like youtube, vimeo works perfectly fine.
I have enabled cache on cloudfront and also the locations are set for best
performance.
Some how is it possible to control chunks size delivered from cloudfront?

Wordpress 3 parent pages are showing posts not their page content.

Wordpress 3 parent pages are showing posts not their page content.

I have a Wordpress 3.6.1 site at: http://ileap.org/
My top level pages (except the home page ) are showing posts not their
given page content. In the backend the content is right. The weird thing
is that the child pages work fine. Clicking around the nav to any child
page you get the appropriate content, its just the parents. Permalinks are
set to just Post Name, and I have changed the setting saved and then reset
to make sure its not that.
This has stumped me for 2 days now. any ideas?
I am running the metrovibes theme.

this.parentNode.parentNode.removeChild is removing the parent

this.parentNode.parentNode.removeChild is removing the parent

In my code the function displayUserTable appends some divs called
tUserBlock to the main div called centralWindow. When you click on a
tUserBlock a div pops up from the tUserBlock.onclick function called
userTableClickListener. I want to be able to close that popup when you
click on it so I've added an onclick function called userPopupClick with
the following code inside:
this.parentNode.parentNode.removeChild(this.parentNode);
But when it's clicked the centralWindow div (the main div) disappears
along with all the contents. But I just want to hide the popup div. I'm
not sure what I'm doing wrong?
Here's the code, the popup part is towards the bottom:
function displayUserTable() {
var tTop = 15;
var tUserBlock = [];
for (var z = 0; z < (UserData.length); z++) {
tUserBlock[z] = document.createElement('div');
tUserBlock[z].className = 'usertable_item';
tUserBlock[z].id = ('userblock' + z);
tUserBlock[z].style.width = "388px";
tUserBlock[z].style.height = "35px";
tUserBlock[z].style.top = tTop + "px";
tUserBlock[z].style.left = "25px";
tUserBlock[z].userID = z;
tUserBlock[z].onclick = userTableClickListener;
centerWindow.appendChild(tUserBlock[z]);
}
}
function userTableClickListener() {
var tID = this.userID;
var tPopup = document.createElement('div');
tPopup.className = 'usertable_popup';
tPopup.id = 'usertable_popup';
tPopup.onclick = userPopupClick;
centerWindow.appendChild(tPopup);
}
function userPopupClick() {
this.parentNode.parentNode.removeChild(this.parentNode);
}
