Memory allocation of 3-d arrays for reading pixel data of images using
libjpeg
I am trying to copy the pixel data of an image to a matrix using libjpeg.
Something is going wrong with the pointers. Please help.
The problem in brief: I pass an int ***p pointer to a function which reads
pixel data. Within the function, I am able to access the elements
p[i][j][k] and perform operations on them but when I try to do the same in
main the program crashes. The main function is:
#include<stdio.h>
#include<stdlib.h>
#include<jpeglib.h>
#include"functions.h"
void main(void)
{
char * file="a.jpg";
int ***p; // to store the pixel values
int s[2]={0,0}; // to store the dimensions of the image
read_JPEG_file(file,p,s); // Function that reads the image
printf("%d",p[0][0][0]); // This makes the program crash
}
The file functions.h reads:
int read_JPEG_file(char * file, int ***p, int **s)
{
int i,j;
//-----------------libjpeg procedure which I got from the
documentation------------
struct jpeg_decompress_struct cinfo;
struct jpeg_error_mgr jerr;
cinfo.err=jpeg_std_error(&jerr);
FILE * infile; /* source file */
JSAMPARRAY buffer; /* Output row buffer */
int row_stride;
if ((infile = fopen(filename, "rb")) == NULL)
{
fprintf(stderr, "can't open %s\n", filename);
return 0;
}
jpeg_create_decompress(&cinfo);
jpeg_stdio_src(&cinfo, infile);
jpeg_read_header(&cinfo, TRUE);
jpeg_start_decompress(&cinfo);
row_stride = cinfo.output_width * cinfo.output_components;
buffer=(*cinfo.mem->alloc_sarray)((j_common_ptr) &cinfo, JPOOL_IMAGE,
row_stride, 1);
s[0]=cinfo.output_height;
s[1]=cinfo.output_width;
p=(int ***)malloc(s[0]*sizeof(int **));
for (i=0;i<s[0];i++)
{
p[i]=(int **)malloc(s[1]*sizeof(int *));
for (j=0;j<s[1];j++)
{
p[i][j]=(int *)malloc(3*sizeof(int));
}
}
while (cinfo.output_scanline < cinfo.output_height)
{
jpeg_read_scanlines(&cinfo, buffer, 1);
for ( i=0; i<cinfo.output_width; i++)
{
p[cinfo.output_scanline-1][i][0]=(int)buffer[0][0+3*i];
p[cinfo.output_scanline-1][i][1]=(int)buffer[0][1+3*i];
p[cinfo.output_scanline-1][i][2]=(int)buffer[0][2+3*i];
}
}
printf("%d",p[0][0][0]); // This works just fine
return 0;
}
I know that something is wrong with the memory allocation but I don't know
what. I tried another test program and successfully allocated a memory
block 500X500X500 integers long, and it was working-it was outputting
random integers without crashing- so lack of memory is not a problem.

Implications of $\|Ax\|_1\leq \|Bx\|_1$
Implications of $\|Ax\|_1\leq \|Bx\|_1$
Let us assume that $A,B\in\mathbb{R}^{m\times n}$ and $\|\cdot\|_1$ is the
(vector) norm-1 defined as $\|x\|_1=\sum_{i=1}^n|x(i)|$, and the induced
matrix norm is $\|A\|_1=\sup_{\|x\|_1=1}\|Ax\|_1$. Let us assume that:
$$ \|Ax\|_1 \leq \|Bx\|_1, \forall x\in\mathbb{R}^n. $$
What does this imply about $A$ and $B$? I can only tell that if $n=m$ and
$B$ is invertible then we may set $y=Bx$ so $x=B^{-1}y$, hence the above
inequality becomes:
$$ \|AB^{-1}y\|_1 \leq \|y\|_1, \forall x\in\mathbb{R}^n, $$
Therefore,
$$ \|AB^{-1}\|_{1}\leq 1 $$
But, I would be interested in the case where $B$ is not assumed to be
invertible and may also not be a square matrix.

How to properly use the IF Statement
How to properly use the IF Statement
Which one is correct and WHY
in both examples we have a function that determines if a certain string is
valid...
(using some other function that's not defined here)
private Validator = new Validator();
public Boolean IsValid(String foo)
{
if (Validator.Validate(foo))
{
return true;
}
else
{
return false;
}
}
in the second scenario we have a function that ends with a TRUE statement
and with no else.
private Validator = new Validator();
public Boolean IsValid(String foo)
{
if (!Validator.Validate(foo))
{
return false;
}
return true;
}
NOW INB4 please dont say that you can simply do it this way
return Validator.Validate(foo);
How to save a few lines its not what i want to know...but the implications
and unknown consecuences ( to me ) of using one method or the other.

skip elements in each function by conditions
skip elements in each function by conditions
how can I skip some elements in each function of jquery by the next
condition:
var number_of_td = 0;
$('td').each(function() {
if (number_of_td == 0) {
if ($(this).attr('id') == "1") {
//skip the next three elements:
//something like: $(this) = $(this).next().next().next();
}
}
else if (number_of_td == 1) {
if ($(this).attr('id') == "2") {
//skip the next two elements
}
}
else if (number_of_td == 2) {
if ($(this).attr('id') == "3") {
//skip the next element
}
}
else if (number_of_td == 3) {
if ($(this).attr('id') == "4") {
//skip the next element
}
}
else {
number_of_td++;
if (number_of_td == 4) {
number_of_td = 0;
}
}
});
for example:
<td attr="1"></td>
<td attr="6"></td>
<td attr="7"></td>
<td attr="9"></td>
//-------------------
<td attr="2"></td>
<td attr="5"></td>
<td attr="3"></td>
<td attr="6"></td>
//-------------------
<td attr="7"></td>
<td attr="2"></td>
<td attr="8"></td>
<td attr="6"></td>
if one of the 4th conditions exists, skip till the td element with attr=2.
in this example, the first td attribute is 1, so it skips till attr=2 and
not check the other elements (attr=6,7,9).
2 is not equal to 1, 5 is not equal to 2, 3 is equal to 3, so it skips
till attr=7, etc.
I hope you can understand my example.
any help appreciated!

Cannot set focus to a form field in a jQuery UI dialog on clicking a jQueryUI menu item
Cannot set focus to a form field in a jQuery UI dialog on clicking a
jQueryUI menu item
I've got a jQuery UI dialog containing a one-field form and the autoOpen
property is set to false at the beginning. There's another jQuery UI menu
on the page and the dialog's open function is binding to the click event
of the menu items. I've been trying to set focus to the only form field of
the dialog when the dialog is open on click of the menu items somehow no
luck. To pinpoint the cause I also added another test button and by
clicking that button I can set focus to the form field. So I'm pretty sure
it's the jQuery UI menu that is preventing the focus of the field. I
wonder if there's any way that I can circumvent this constraint. Any
insight is appreciated. Thanks!

How to connect a data center network to a cloud provider with VPN
How to connect a data center network to a cloud provider with VPN
We have our production environment on EC2 classic, and we have a lease on
some servers in a managed hosting environment. We would like to put a
portion of our backend service in the data center, but there is no
security built into the application yet, so we need to rely on private
networks and VPN. I think this will be easier once we migrate to VPC as
AWS already provides this kind of service, but we are not there yet.
Network Description
EC2 Classic puts all instances in 10.0.0.0/8. Our data center also has a
subnet within that range, but I suspect we can change that. There are two
routers at the data center that can connect an IPSEC VPN.
Service Description
The services running in the data center need to be able to initiate
connections to services in EC2 and also receive connections initiated by
services in EC2.
Ideas
I'm sure that if our services at the data center only needed to initiate
connections to services in EC2, then it would just be a matter of setting
up VPN endpoints in EC2 for the routers at the data center to connect to,
use a different subnet in the data center, and finally, route all
connections to 10.0.0.0/8 over the VPN.
For the other direction, is the best option to configure an extra route on
all EC2 instances that need to initiate connections to services in the
data center?

Desktop icons missing after "logging on" to 13.04
Desktop icons missing after "logging on" to 13.04
So I signed in to my Ubuntu 13.04 (dual booted) computer today and I
noticed something strange, the unity lancher had appeared as soon as I
signed in, but sign in box has stayed where it is and not disappeared,
along with the Ubuntu logo and white dots all over the screen. In addition
to this my desktop icons have disappeared.
Any advice as how I could go about getting rid of the login screen and
retrieve my icons?
Cheers.

Hausdorff spaces from continuous functions
Hausdorff spaces from continuous functions
The question is to prove a topological space is Hausdorff if for every $p$
in the space there exists a continuous function $f_{p}$ such that
$f^{-1}(0) = \{p\}.$ (The inverse here is implied as converse, not a
bijective inverse).
My thinking is that if we take the open subset of $\mathbb{R}$ $(-1;1)$
for each $f$ since the map is continuous we get open sets containing
$p_i,$ and it boils down to showing the intersection is empty. I can't
quite follow this important part through.
Thanks in advance.

Recieve 400 Bad Request when using Jquery Form Plugin
Recieve 400 Bad Request when using Jquery Form Plugin
I changed my code to using the Jquery Form Plugin so that I could upload
pictures. My original form was simple
$.ajax({
type: "POST",
url: "register.htm",
data:{
account_name: $('#regAccount_name').val(),
pwd: MD5($('#regPwd').val()),
fname: $('#regFname').val(),
lname: $('#regLname').val(),
},
success: function(data){
changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully
Registered');
},
error:function(e){
console.log("sendRegistration(): " + e);
}
});
but changed to this
var options = {
beforeSend: function()
{
//alert(MD5($('#regPwd').val()));
// document.getElementById('regPwd').value =
MD5($('#regPwd').val());
},
uploadProgress: function(event, position, total, percentComplete)
{
},
success: function()
{
changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully
Registered');
},
complete: function(response)
{
},
error: function(e)
{
console.log("sendRegistration(): " + e);
}
};
$("#regForm").ajaxForm(options);
However now I get a 400 Bad Request which I take it to mean the my
controller isn't even picking up the request. Here's my controller code:
@RequestMapping("/register.htm")
public String register(// @RequestParam("regProfilePic") File pic,
@RequestParam("regAccount_name") String account_name,
@RequestParam("pwd") String pwd,
@RequestParam("fname") String fname,
@RequestParam("lname") String lname,
ModelMap params){
setup();
System.out.println("Register");
service.registerUser(fname, lname, account_name, pwd);
return "MenuFrame";
}

How would I go about creating a random string of text for use with file
names?
I am uploading photos and renaming them upon completion. All photos are
going to be stored in one directory so their filenames need to be unique.
Is there a standard way of doing this?

When should I prefer a clone over an reference in javascript?
When should I prefer a clone over an reference in javascript?
at the moment I'm writing a small app and came to the point, where I
thought it would be clever to clone an object, instead of using a
reference.
The reason I'm doing this is, because I'm collecting objects in a list.
Later I will only work with this list, because it's part of a model. The
reference isn't something I need and I want to avoid having references to
outside objects in the list, because I don't want someone to build a
construct, where the model can be changed from an inconsiderate place in
their code. (The integrity of the information in the model is very
important.)
Additional I thought I will get a better performance out of it, when I
don't use references.
So my overall question still is: When should I prefer a clone over an
reference in javascript?
Thanks!

cakephp multiple domains & Configure::write
Running multiple domains on one install. In bootstrap I have:
Configure::write('Application.name', 'example1.com');
Configure::write('Application.name', 'example2.com');
What's the best way to define these variables so that I can check my main
domain and set them up all at once?

Currently following a checklists tutorial built with io6 in mind. I'm
using xcode 5, ios7 sdk. The tutorial hasn't been updated for IOS7 but I
didn't want to stop my learning so decided to go ahead and work with the
outdated tutorial and hopefully use it as a learning experience. Using
reading of official Apple docs and extensive googling as my guide along
the way.
Very early I've run into an issue already and not sure what is wrong. I
noticed that the autocomplete had part of the methods below crossed out (a
deprecation maybe?). The issue is definitely coming from the code below
because once I remove it the simulator loads the app fine.
Code causing crash:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:@"ChecklistItem"];
return cell;
}
Here is the stack trace:

Objective-C UICollectionView Scroll Up/Down
Objective-C UICollectionView Scroll Up/Down
Does anyone know, what method for UICollectionView, while scrolling
Up/Down. I need to change UICollectionView's Header while scrolling down.I
am doing own calendar View.
I have following method that creates header view for section
- (UICollectionReusableView *)collectionView:(UICollectionView
*)collectionView viewForSupplementaryElementOfKind:(NSString *)kind
atIndexPath:(NSIndexPath *)indexPath
{
ASCalendarHeaderView *calHeader = [self.calCollectView
dequeueReusableSupplementaryViewOfKind:kind
withReuseIdentifier:@"CalendarHeader" forIndexPath:indexPath];
calHeader.MonthYearLabel.text = [calendar
getCurrentMonthYear:calendar.today];
[calHeader setNeedsDisplay];
calHeader.MonthYearLabel.textAlignment = NSTextAlignmentRight;
if (indexPath.section){
[calendar getNextMonth:calendar.today];
NSLog(@"Some Text");
}
return calHeader;
}
But it increment month while I am scrolling up. Is there is method that
mean while scrolling up and while scrolling down separately?
Thanks

This is frustrating. I searched about it a lot but none of the results
help me. I tried subprocess but I still cant get it to work. Basically I
want to get this line to work:
appName = "ap01"
optna = "-server"
optnb = "-filename=c:/test.VS"
optnc = "-display=1"
os.system('start "VSM" "C:/bin/" {appName, optna, optnb, optnc} ')
In CMD I would simply type
CD C:/bin/
press enter and then:
ap01 -server -filename=C:/test.VS -display=1

About the EX1-9 of K&R
About the EX1-9 of K&R
Here's the text of Exercise 1-9 from the book 'The C programming language'
by Ritchie&Kernighan:
Write a program to copy its input to its output, replacing each string of
one or more blanks by a single blank.
To me the simplest way of solving that problem is writing
int single_byte = getchar();
while (single_byte != EOF) {
putchar(single_byte);
if (single_byte == ' ')
while ((single_byte = getchar()) == ' ')
;
else
single_byte = getchar();
}
though I was told (last night in the #c channel of irc.freenode.net) it
would be more readable getting rid of the nested while by implementing a
comparison between the last character saved and the one just read. What I
thought is kind of this:
int current_byte = getchar();
if (current_byte == EOF)
return 1;
putchar(current_byte);
int previous_byte = current_byte;
while ((current_byte = getchar()) != EOF) {
if (current_byte == ' ' && previous_byte == ' ')
;
else
putchar(current_byte);
previous_byte = current_byte;
}
that does not satisfy me at all: starting from the first if-statement (for
the case when there's nothing to read). Additionally I wish I could push
the last two lines before the while inside the loop; the less I should
distinguish the beginning from the rest of the execution, the happier I am
!

Swap Class of Element
Swap Class of Element
I have the following code:
<a href="#" class="more">text</a>
How can I toggle the class between "more" and "less" when clicked?
$('a').click(function (e) {
e.preventDefault();
var $this = $(this);
$this.toggleClass('more', 'less');
});
But I get the class changing from "more" to "" and not to less.
Thank You, Miguel

(CodeIgniter) Unable to add to Cart Class
(CodeIgniter) Unable to add to Cart Class
I've just started playing around with the shopping cart class for
CodeIgniter (version 2.1.4) and I've been following tutorials that help
explain it. But for some reason I am unable to successfully add a a simple
array to the cart.
Here is my implementation of the cart class:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Cart extends CI_Controller {
public function __construct() {
parent:: __construct();
}
public function index() {
$nav["navigation"] = $this->getCategory->getCategories();
$this->load->view("header");
$this->load->view("scripts");
$this->load->view("nav", $nav);
$this->load->view("cart");
$this->load->view("footer");
}
function add() {
$data = array(
"id" => "42",
"name" => "pants",
"quantity" => 1,
"price" => 19.99,
"options" => array("size" => "medium")
);
$this->cart->insert($data);
var_dump($this->cart->contents()); //This should output the array!
}
function show() {
$cart = $this->cart->contents();
echo "<pre>" . print_r($cart) . "</pre>"; //Nothing here either!
}
function update() {
$this->cart->update($data);
redirect(base_url()."cart");
}
function total() {
echo $this->cart->total();
}
function remove() {
$this->cart->update($data);
}
function destroy() {
$this->cart->destroy();
}
}
But if I go to the add function the var_dump just displays "array(0) { }".
Same result if I navigate to the show function.
Here is my autoload config showing that I have autoloaded the cart library
has been loaded:
$autoload['libraries'] = array("database", "session", "cart");
$autoload['helper'] = array("html", "url", "form");
I know it's something really simple and obvious I'm missing, but right now
I'm just left baffled. Any suggestions?

how the javascript compare the number and string?
how the javascript compare the number and string?
I know the meaning of ===, it will check whether the operand is identical
or notC so 1 === '1' will result false, but 1 == '1' result true, but
typeof 1 is number and typeof '1' is string, so how javascript compare 1
== '1', are there any converting, and how?

Left-floated div place below another div
Left-floated div place below another div
I have two divs whereas (div 1) is floated left while (div 2) is floated
right. I am creating a responsive layout where when the viewport changes,
(div 1) will go under (div 2). I created a simple image via MS Paint for
an easier illustration and also some code. Also, both contain dynamic
content so their heights must not be fixed.
No javascript (if possible) just plain CSS. I only know how to put div 2
under div 1 but not the other way around.
Does anyone know how I could achieve this?
HTML:
<div id="div1" style="float: left;">

</div>

MySQL: my.ini not read
MySQL: my.ini not read
I have MySQL 5.6 installed on Windows 7 64 Bit and I can't seem to get it
to read my my.ini file. I've put the file into the base installation
directory, the Windows directory and C:\, but it doesn't look like it's
being read, even though all paths are listed here:
http://dev.mysql.com/doc/refman/5.1/en/option-files.html
My my.ini file doesn't do much, I just took the my-default.ini as a base
and added [mysqld] max_allowed_packet=100000000 because that default limit
of 4MB is bad for BLOBs.
When I start mysql.exe and check the variable I find that it's still at
4MB, even after restarting the server (both via the services menu in the
control panel and via mysqld -shutdown + mysqld -startup) and restarting
Windows.
I have Windows 7, 64 bit. Can anyone help me, please?
Thanks in advance!

Concatinating values of a matching string in an arrray
Concatinating values of a matching string in an arrray
I have a string array[2] as follows:
1st Array 2nd Aray
"100101" "Testing123"
"100102" "Apple123"
"100101" "Dog123"
"100104" "Cat123"
"100101" "Animal123"
I would like to concatenate all elements of the 2nd array if the elements
in the first array match.
For example elements of the first array that match are "100101", "100101"
and "100101". So a string with the concatenated values of the respective
2nd array would be as follows:
"Testing123 Dog123 Animal123"
How could this be achieved elegantly?

Bootstrap 3 button-group and input-group in one row
Bootstrap 3 button-group and input-group in one row
if you have a look at the following example, you can see that the
input-group is bwloe the button-group:
http://bootply.com/81723
I already tried putting both groups into floating divs, but the browsers
still break the row. I noticed that ".btn-group, .btn-group-vertical"
contain a "display: inline-block". After commenting this line out, the row
doesn't break, but i don't have a space between both div (although I
thought to get one by "padding-right: 16px")

Oracle return custom type as SQL rows in package
Oracle return custom type as SQL rows in package
I'm aiming to define a custom type for an employee (ID and name), and then
a custom type for a table of employees. I have created a function within a
package that returns the table of employees type. All of this compiles
fine.
The problem is when I try to call the function and retrieve the results as
SQL rows, Oracle produces the error:
ORA-00902: invalid datatype
Package specification:
type t_employee is record
(
id number,
name varchar2(300),
);
type t_employees is table of t_employee index by pls_integer;
function get_employees(input1 varchar2) return t_employees;
Package body:
function get_employees(input1 varchar2)
return t_employees
is
employee_list t_employees;
begin
employee_list(1).id := 123;
employee_list(1).name := 'Stan';
employee_list(2).id := 456;
employee_list(2).name := 'Jan';
return employee_list;
end get_employees;
I call it through the apex SQL Workshop like so:
select * from table(my_pkg.get_employees('some input'))
This then gives the invalid datatype error. How can I return this custom
type as SQL rows (in the same way as if I was querying a standard table)?

pagination for setting the page size . I ran into one issue that when i
filtered the data and then done my own pagination then it does not work as
in Kendo grid in url there comes Grid-page-size which set first times and
it never changed .
How can i solve this ? It will be appreciable if anyone solved this problem?
Here is my code for grid :-
@(Html.Kendo().Grid(Model)
.Name("Grid")
.Columns(columns =>
{
columns.Bound(o => o.info).Title("Info").Width("150px");
columns.Bound(o => o.name).Title("Name").Width("90px");

neo4j cypher index query
neo4j cypher index query
I was used to use node_auto_index( condition ) to search for nodes using
indexes, but now i used batch-import (
https://github.com/jexp/batch-import/ ) and it created indexes with
specific names ( type, code, etc ). So, how to do a cypher query using
indexes on multiple properties ?
old query example :
START n = node : node_auto_index( 'type: NODE_TYPE AND code: NODE_CODE' )
RETURN n;
how to do the 'same' query but without node_auto_index and specific index
names ?
START n = node : type( "type = NODE_TYPE" ) RETURN n;

How to output currency symbols with Prawn?
I am trying to output currency symbols in Prawn with a helper method like
this:
def price(number)
@view.number_to_currency(number, :unit => "€")
end
I then use it like this:
price(@invoice.total)
Unfortunately it's not working and instead of € I get € in my PDF
documents.
(The same number_to_currency function works great outside of Prawn by the
way.)
Can anybody help?

MATLAB/Octave - Problems with mesh plot
MATLAB/Octave - Problems with mesh plot
I am trying to mesh the following function in Octave:
function C = istep(x)
A = x < 0.75
B = x > 0.25
C = A & B
endfunction
D = rand(10);
mesh(istep(D));
using 10x10 (random) matrix as an input. The mesh function however fails
and fires
invalid value for array property "zdata"
Note: Meshing D itself works fine. The function istep also returns 10x10
"matrix" with expected values. I suspect the error lies in the fact that
the internal format of the output is not treated as a matrix, but rather
as a data "array" or something more abstract. I am not sure how to change
it however.
Also, multiplying the output by eye(size(D)) solves the issue and allows
to plot the matrix (i suspect it casts the output to matrix
automatically). I do not find this very elegant though and would like to
avoid it if possible.
Edit: spy() works fine directly on the output, without need of
multiplication by eye()
Question: What shall I change in the code so I am able to plot the matrix
istep(D)?

Optimal number of database connections (node-mysql)
Optimal number of database connections (node-mysql)
By default, node-mysql limits the maximum number of mysql connections in a
connection pool to 10.
Is there an optimal number of connections I should set it to? ( is there a
number beyond which performance degrades, instead of increasing? )
Thanks

Google Script for Spreadsheet - how can I prompt the user to select a range?
Google Script for Spreadsheet - how can I prompt the user to select a range?
I've been doing a lot of work with Google Script to automate some peer
evaluation processes.
One result is a spreadsheet with a lot of review data that I need to sort,
group and summarize. The script is working fine for the hard-coded sort
column.
But I really want to be able to sort on different columns at different
times, and I'd like the sort/group/summarize script to prompt the user to
select the sort/group column at runtime.
I've explored the UI stuff a bit, but I haven't seen how to prompt the
user to select a range (or column or anything else) on the sheet.
Thanks in advance.

and
'our-services' => 'services/index'
i am calling index function of service controller in navigation bar as
$this->createUrl('/services/index')
and i have already tried it by removing first slash before services and
also by adding last slash after index but no luck.
I need to customize my url for any language i use. yeah for sure url will
be same for both language but the content of pages will be differ as per
language( text is working fine for each language as

Trigger image transition by hovering over a text link
Trigger image transition by hovering over a text link
OK, I'm a complete rookie and have gleemed the coding I have so far from
various resources online and adapted it to suit my needs, so be gentle :P
Basically, I have a nice CSS transition happening when hovering over an
image. However, I want to put a text link beneath said image, that will
trigger the same image transition when you hover over the text link. Is
this possible? I've been searching for a result for some time now and
still not cracked this one!

Comments only posting to most recent status update
Comments only posting to most recent status update
The news feed on the sites dashboard I'm working on has multiple items
from different users; and can also be commented on. However, whenever you
write a comment under each post, it only posts to the post at the top of
the feed (the most recent one). Comments are posted instantly by pressing
the enter key, which then runs this JS code which is on the index.php
page.
$(function(){
$('#comment_body').live( 'keypress' , function (e) {
var boxVal = $(this).val();
var sendTo = $('#to_id').val();
if ( e.keyCode == '13' ) {
e.preventDefault();
$.post( 'instantcom.php' , { 'comment_body' : boxVal ,
'activity_id' : sendTo } , function () {
// reload data or just leave blank
} );
$('#comment_body').val('');
}
} );
});
Then, the HTML for the comment box on each post is as follows:
<p align="center" style="height:45px;">
<input type="text" name="comment_body" id="comment_body"
style="margin-top:12px;border:1px solid blue
!important;width:329px;height:21px;" />
<span class=" glyphicons-icon camera"
style="position:relative;bottom:50px;left:155px;"></span></p>
<input name="type" type="hidden" value="a" />
<input name="activity_id" id="to_id" type="hidden" value="' . $act_item_id
. '" />
The ' . $act_item_id . ' is just a PHP variable which contains the unique
ID of the status update.
So then, any ideas as to why comments are only posting to the most recent
posts instead of the ones they're meant to post to?

Styling your action bar android

The general action bar in android is quite dull is there any way of
editing this bar in terms of colour, style and the position of icons
rather than having icons arranged right to left can you have a single icon
in the middle this is just an equiry about how far can you customize the
action bar or will you just have to nest images in layouts ?

I'm trying to create a messaging system that uses ajax that doesn't have
to reload when the message is submitted. I have a .js file that uses an

something wrong or because you cant use JQuery and Javascript in the same

How does one read JavaScript API like Mongoose
How does one read JavaScript API like Mongoose
I'm a java developer. I really like to learn javascript. I'm finding it
very difficult to pick-up a library and just learn/use it for two reasons:
1) There is no decent auto-complete. I've tried, eclipse, vjet, nodeclipse
and webstorm...each has its own frustrating set of issues. Maybe the
language is such that, autocomplete is super-difficult. 2) The API
documentation is extremely confusing. I guess it is because I'm new to
JavaScript.
For example, I wanted to figure what the callback function in
mongoose.connect method does and how to declare it. So I checked the api
doc. All it says is that the callback is a function...it doesn't say how
many params it takes, what the values of the params are under various
invocation scenarios...etc.
I feel like I'm missing something...
