which shows the variation in air temperature measured at ten minutes
intervals (which I have converted into decimal days).
I'm attempting to compute the spectral properties of the time series in
order to see which periods are dominant. So far I have tried:
x = data(:,1);
y = data(:,2);
N = length(x);
% Time specifications:
Fs = 1; % samples per second, 10 minute samples
freq = 0:N-1; %Numerators of frequency series
freq = freq.*Fs./N;
% Fourier Transform:
X = fft(y)/N; % normalize the data
% find find nuquist frequency
cutOff = ceil(N./2);
% take only the first half of the spectrum
X = (X(1:cutOff));
% Frequency specifications:
freq = freq(1:cutOff);
% Plot the spectrum:
figure(i);
subplot(211);
plot(x,y);
subplot(212);
plot(freq,abs(X));
Is the sampling frequency specified here correct?
I am not convinced that I have done this correctly, could someone please
specify the correct or advised way of doing this? The reason I say that
this must not be correct is because I have a peak in the spectra at some
value that doesn't seem to mean much, and therefore would like to see how
someone who is experienced in performing these kinds of analysis would
tackle this.
I have the following data:

which shows the variation in air temperature measured at ten minutes
intervals (which I have converted into decimal days).
I'm attempting to compute the spectral properties of the time series in
order to see which periods are dominant. So far I have tried:
x = data(:,1);
y = data(:,2);
N = length(x);
% Time specifications:
Fs = 1; % samples per second, 10 minute samples
freq = 0:N-1; %Numerators of frequency series
freq = freq.*Fs./N;
% Fourier Transform:
X = fft(y)/N; % normalize the data
% find find nuquist frequency
cutOff = ceil(N./2);
% take only the first half of the spectrum
X = (X(1:cutOff));
% Frequency specifications:
freq = freq(1:cutOff);
% Plot the spectrum:
figure(i);
subplot(211);
plot(x,y);
subplot(212);
plot(freq,abs(X));
Is the sampling frequency specified here correct?
I am not convinced that I have done this correctly, could someone please
specify the correct or advised way of doing this? The reason I say that
this must not be correct is because I have a peak in the spectra at some
value that doesn't seem to mean much, and therefore would like to see how
someone who is experienced in performing these kinds of analysis would
tackle this.

Is there any api from sdk which allows to register own application to this

Why hints are not visible when a cursor is over them?
Why hints are not visible when a cursor is over them?
My question concerns visibility of hints in an application using
DevExpress (C#) controls. The application has a panel on which there are
several controls, and only one appears at a given moment. A user can
choose which control should appear by switching among them. The controls
have their bar with several buttons (different buttons for each type of
control).
The problem is that the hints on the buttons sometimes do not appear when
the mouse cursor is over them. They appear after opening the application,
but when the user switches to a control of the same type, the hints are
not visible. When the user switches to a control of another type, the
hints can appear, but not always (I could not find the rule). But always,
when the user goes to a window of another application and returns, the
hints appear. The property ShowScreenTipsInToolbars for the bar manager
has the value true during execution of the program.
Do you know the cause of this strange behavior? And what to do to make the
hints always visible when a mouse cursor is over the buttons? I am not the
author of the application (I was asked if it is possible to solve the
problem) and I cannot give too many technical details.

How to replace Linux Kernel error messages with my defined error messages?
How to replace Linux Kernel error messages with my defined error messages?
I have created a shell and when I give wrong number of arguments like
insufficient arguments to cp commands I receive the Linux shell error
message like what you will receive if you type cp fork.c as follows:
mysh> cp fork.c
cp: missing destination file operand after `fork.c'
Try `cp --help' for more information.
How can I bypass this error message and print my own error message like
Dude! this is an error ?

SERIOUS help port forwarding on my router?
SERIOUS help port forwarding on my router?
Okay, so I know that these kind of questions are pretty popular on SO, but
please hear me out. I have a belkin router, model F9K1102 v1. I also have
a Westell Dual Connection modem, model A90-220015-04. Now, I have done
port forwarding before, although it was with the same modem and a
different (Cisco) router. My modem is IP 192.168.0.47 and my router is
192.168.2.1. I followed the following tutorial to set up port forwarding
on the Belkin router:
http://portforward.com/english/routers/port_forwarding/Belkin/F9K1102v1/Apache.htm
And set up the following under "Virtual Servers":
Yet, whenever I try accessing my public IP (from whatsmyip.org) via my
iPhone on 4G, it can't find the server. The connection times out. Online
port sniffers say that port 80 isn't open. This is becoming very
frustrating and I really need it to work. Verizon is my ISP and I am
running Ubuntu Server 12.04, btw.
Any help towards resolving this would be GREATLY appreciated. Thanks in
advance!!

I'm trying to do is that if a domain name ($line) is a .com and has no
numbers then echo it. All of the preg_replace and strlen seems to be
working, but I can't get it to only perform the way I need. I need ot put
the preg_match outside of the <=40 rule as it may be causing confusion?

work, but I have to try and boot it up 3 times before it actually works
(then it is fine). iOS on the other hand just doesn't work.
I'm using Titanium 3.1.3.
I get the following messages in the console:
[INFO] : No module resources to copy
[INFO] : No CommonJS modules to copy
[INFO] : Compiling localization files
[INFO] : Skipping xcodebuild
[INFO] : Finished building the application in 13s 974ms
[INFO] : Running application in iOS Simulator
[INFO] : Launching application in iOS Simulator
[INFO] : Focusing the iOS Simulator
[INFO] : Application has exited from iOS Simulator
[INFO] : Project built successfully in 17s 497ms
Apparently there are no errors, but the simulator just doesn't pop up.
There are a few lines of code before all this I didn't include, but I
don't think those are important. Furthermore, I've looked all over the
internet and even Stackoverflow and I can't find a solution to my problem.

Sometimes, html pages generated with jstl don't render completely
Sometimes, html pages generated with jstl don't render completely
I am working with spring to make a web application. For UI, I use jstl.
But when I run the app on tomee, my page doesn't show up correctly. I have
looked at the html source code of the page in my browser and it's not
complete. It seems that jstl doesn't generate all the page. What can be
the reason of that ?

Try catch and re-throw exception
Try catch and re-throw exception
I saw some code the other day in one of our projects that uses a try catch
and re-throws the caught exception like this:
try
{
exceptionProneCode();
}
catch(Exception ex)
{
throw ex;
}
Nothing else was done with the exception in the catch block so I'm not
even sure why it's re-thrown. I can't see any benefit to actually throwing
the same exception again and doing nothing with the exception.
If you re-throw an exception that's caught in the catch block, how does C#
handle this? Does it get stuck in an infinite throw/catch loop? Or does it
eventually leave the try catch?

Linux C programming exec as user
Linux C programming exec as user
I have an program which I run as root. I would like the program to execute
another application as a normal user. I tried setgid() and it works, but I
can't then go back to root or another user. The program for the time being
is very simple;
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
int main(int argc, char *argv[] )
{
if ( argc != 2) {
printf("usage: %s command\n",argv[0]);
exit(1);
}
setgid(100);
setuid(1000);
putenv("HOME=/home/caroline");
putenv("DISPLAY=:0");
system(argv[1]);
seteuid(1001);
putenv("HOME=/home/john");
putenv("DISPLAY=:1");
system(argv[1]);
return 0;
}
How can I do this? It's like the action of command "su $user-c $command"
Respect R.

UILabels within a UITableView cell are overlaying each other in iOS7
UILabels within a UITableView cell are overlaying each other in iOS7
I didn't have this problem with iOS6, but am currently having it with
iOS7. I have a UITableView and you can see 8 cells at the time the view is
loaded. Each populated with different names from and array. If you scroll
down, the next two cells look good, but everything past that gets text
laid on top of it; That text being the contents of what was in the
previous cells. So the 10th cell will have what was in the first cell, as
well as what is supposed to be in the 10th cell laid on top of it.
Code:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [self.tableView
dequeueReusableCellWithIdentifier:CellIdentifier
forIndexPath:indexPath];
if (cell == nil)
{
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
//Create Label for Name inside cell
UILabel *name = [[UILabel alloc] initWithFrame:CGRectMake( 7.0,
5.0, 300.0, 30.0 )];
[name setText:[self.entriesArray objectAtIndex:indexPath.row]];
//Check to see if current person is a Parent or Child
NSString *class = [self.database
getCellDataWithMembership:[self.MembershipArray
objectAtIndex:indexPath.row] andColIndex:4];
if([class isEqualToString:@"CHILD"])
{
name.textColor = [UIColor colorWithRed:25.0f/255.0f
green:111.0f/255.0f blue:45.0f/255.0f alpha:1.0f];
name.font = [UIFont fontWithName:@"Helvetica-Bold" size:17.0];
}
[cell.contentView addSubview:name];
return cell;
}
My skill with Table views is makeshift at best. I've been reading lots of
documentation and researching solutions, but was not able to come up with
a solution. I just find it odd that it works perfect for iOS6, but not for
iOS7.
So it fetches a person's name from an array and I want to populate the
cells with those names. I was able to originally accomplish this using:
cell.textLabel.text = [self.entriesArray objectAtIndex:indexPath.row];
if([class isEqualToString:@"CHILD"])
{
cell.textLabel.textColor = [UIColor colorWithRed:25.0f/255.0f
green:111.0f/255.0f blue:45.0f/255.0f alpha:1.0f];
cell.textLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:17.0];
If I use that instead of the "name" UILabel actions from the first code
block, then it displays the names perfectly with no text overlay, but what
becomes an issue is the text color. If they are labeled as a CHILD then
they should be green text and bold. However, after scrolling down, every
person becomes green when they shouldn't be.
Sorry for the lengthy question. I've been working on this and racking my
brain around it and I just can't seem to figure it out. Any help would be
greatly appreciated.

Cordova Media API - playAudio() is slow
Cordova Media API - playAudio() is slow
Does anyone have experience with playAudio() being really slow?
When I run
playAudio('http://audio.ibeat.org/content/p1rj1s/p1rj1s_-_rockGuitar.mp3'),
it seems like it downloads the entire mp3 before even playing it.
Is there a way to start playing instantly? Or, is there a good example of
an implementation of the API that actually plays right away?

Django-CKEditor won't render images
Django-CKEditor won't render images
I've installed Django-CKEditor and configurated it for development purposes.
Now I can edit text and save it to db as text field. But with inserting
images I have major problems...
I can insert image and it seems to save properly to local host (to correct
folder) but when rendering image to preview or text editor I get only
broken image picture. Apparently I haven't configured settings.py
correctly. Main items from settings.py:
MEDIA_ROOT = ''
MEDIA_URL = '/media/'
STATIC_ROOT = ''
STATIC_URL = '/static/'
CKEDITOR_UPLOAD_PATH = 'media/uploads/'
CKEDITOR_UPLOAD_PREFIX = 'media/uploads/'
Also tried similar configuration than django-ckeditor testproject has but
faced similar broken rendering images.
I'm using windows environment for development
Any ideas what is wrong or where to start solving this?

Example have a frame on the website and 3 boxes inside and I can grab them
and position
them on the screen. And at the end to save it as PDF, Image or anything....
I am only throwing ideas, what would be the best approach to use that and
save it in some kind of viewable format, but simplest way doesn't need to
be complicated.
Thanks for help.
I am building the django website where I am using drag & drop html5
elements, what I would like to achieve is if I layout elements on the
screen to save it as PDF or Image or any available (simplest way) output
form.
I was looking at this solution:

mapping between two text file contain arabic characters c#
mapping between two text file contain arabic characters c#
I have text file contains data like as:
ID 1 Name Mary Mark 89 ID 2 Name Mai Mark 67
and I have another txt file contains data : ID Mobile 1 0993209320 2
0943043094
I want to create excel file which contains only two columns: Mobile
Message 0993209320 ID 1 Name Mary Mark 89 0943043094 ID 2 Name Mai Mark 67
to do this,I tried the following code, it works fine, and the required

file to Arabic, the code created excel file, but Empty, what should I do

How to load search data from twitter onto a website?
How to load search data from twitter onto a website?
I'm in the process of making a website that will show users the latest
tweets people have made about a few different topics. My idea was to use
python on the server to do a search through the twitter API every few
minutes, and after doing some parsing, drop the results into a database.
Then when users access the website, it would use javascript to access
either a python or php file on the server to fill in the divs on the site
with the tweets.
Is this the best way to manage what I want? A majority of the users will
be accessing the site from their phones, so I'd rather keep the load times
down as much as possible. Any advice would be appreciated.

Intel Pentium Floating-Point Division Bug, 1994 used on Python
Intel Pentium Floating-Point Division Bug, 1994 used on Python
This math equation...
(4195835 / 3145727) * 3145727 - 4195835
is supposed to equate to 0. According to the book Software Testing (2nd Ed),
If you get anything else, you have an old Intel Pentium CPU with a
floating-point division buga software bug burned into a computer chip and
reproduced over and over in the manufacturing process.
Using Python 2.7, I get -1050108 in command line.
Using Node I get 0, just as I would in the calculator
Any deeper explanation for this? This was originally brought up due to a
bug in the video game Disney's Lion King, 1994. I thought I would test the
equation on a few things.

MIPS multiplication via addition
MIPS multiplication via addition
I'm currently using QtSpim for a MIPS program. The objective is to use
addition to multiply. This is my code which is relatively straightforward:
.data
inputX: .word 5
inputY: .word 4
tempX: .word 0
constantOne: .word 1
finalX: .word 0
.text
main:
lw $t1, inputX
lw $t2, inputY
lw $t0, tempX
lw $t3, constantOne
lw $t4, finalX
beq $t2, $zero, Exit #when Y equals zero, X is already zero so exits.
Loop: beq $t2, $t3, yIsOne #when y is one skip rest of loop
add $t0, $t1, $t1 #actual "multiplication".
sub $t2, $t2, $t3 #what makes loop continue
bne $t2, $zero, Loop #while Y isnt yet 0.
yIsOne: add $t0, $t0, $t1 #adds X to 0 or the multiplied Xs
Exit:
sw $t4, finalX
When I run the program, I get this:
R8 [t0] = f
R9 [t1] = 5
R10 [t2] = 1
R11 [t3] = 1
R12 [t4] = 0
which was very baffling so I went through single-step and the first time
t0 should've had 5 added to its total, it became a. It stayed that way
until after my yIsOne jump, which is where it became f. Everything else
appears to work fine. It jumps back up for the loop correctly. t2 gets
subtracted by one every time. Any help is appreciated. Thanks.

How to custom format a cell in an AdvancedDataGrid in flex?
How to custom format a cell in an AdvancedDataGrid in flex?
I would like to create an AdvancedDataGrid where one of the cells requires
some layout work involving images and text. Here is the top level view of
the problem that I am trying to solve
(My grid looks like this - Property "name" in the first column and
Property "value" in the second)
<mx:AdvancedDataGrid showHeaders="false" defaultLeafIcon="{null}">
<mx:columns>
<mx:AdvancedDataGridColumn dataField="Property"
headerText="Property" backgroundColor="#E5EFF5" width="0.4"
wordWrap="true"/>
<mx:AdvancedDataGridColumn dataField="Value" headerText="Value"
backgroundColor="white" width="0.6"/>
</mx:columns>
</mx:AdvancedDataGrid>
(The dataProvider for the grid looks something like the following)
var retVal:ArrayCollection = new ArrayCollection([
{Property:'AA', Value:1},
{Property:'BB', Value: <Object that requires custom formatting when
displayed in the grid>},
{Property:'CC', Value:"Simple string"}
]);
Property BB alone has a more complex view involving laying out images and
text in a particular layout. Every other property has a simple string or
numeric value that does not require any special formatting.
Things like itemRenderer are proving to be too difficult to use for me
given that not all my column entries for a given column are formatted in
the same way when displayed inside the grid.
I am using an AdvancedDataGrid because it provides tree like navigation
within the grid (using children) and that is something that I will
eventually need.
An example would be helpful as I am new to flex.
Thank you.

Cropping an image taken from AVCaptureStillImageOutput
Cropping an image taken from AVCaptureStillImageOutput
I am trying to crop an image taken from AVCaptureStillImageOutput but
unable to properly crop at the correct rectangles.
My preview of camera video is 320x458 frame and the cropping rectangle is
present inside this preview frame which has the co-ordinates and size as
CGRectMake(60, 20, 200, 420).
After taking the picture, I receive the image from
NSData *imageData = [AVCaptureStillImageOutput
jpegStillImageNSDataRepresentation:imageDataSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
UIImage *finalImage = [self cropImage:image];
Afterwards I am trying to crop this actual image of size 1080x1920 with
the below function. I am getting a wayward clipping and the resultant
image is way out of the actual rectangle! ;(

CGRect rect = CGRectMake(60, 20, 200, 420);
CGSize boundSize = CGSizeMake(320, 458);
float widthFactor = rect.size.width *

send http request post with raw data in Javascript and retrieve with Perl
send http request post with raw data in Javascript and retrieve with Perl
experts, some questions to ask, very grateful for your guidance.
I saw some rest client like Chrome Postman provided 2 ways of Post
request: form data and raw data. I see raw data can be in JSON format. I
didn't know how to implement this request in Javascript.
How can I handle this request if I use Perl as server side language? How
to retrieve the JSON data from the request?
Does the Get method put arguments in url as "?name=value&", while Post
method in some format of data such as JSON/XML? Does that the main
difference of the 2 methods? Get arguments can be got by parsing url,
method type can from ENV variable value, so how the JSON data was
transmitted?

Webapp - Best method to limite usage of user
Webapp - Best method to limite usage of user
I'm building a webapp where I would like to limit the user of over using
the application.
I would like to limit how many time the user send email notification each
month.
The way I was thinking of doing this is by logging every notification with
user_id date time. So before Sending a notification I will select * WHERE
user_id Between Date and Date+30. And do a validation that the number of
entry is smaller then the limit.
Is there an easy and faster way to do this. I'm a bit nervous when I will
have 1/2 millions logging entry.

What can I do to show the menu on bottom of my application and not on top
action bar?
I'm trying to make an option menu in android like this link
http://developer.android.com/guide/topics/ui/menus.html#options-menu
but my developed menu shows not on bottom of my page but in top action bar.
my xml is bellow my_options_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
android:icon="@drawable/menu_addnew"
android:title="ÍÝï"
android:showAsAction="ifRoom"/>
<item android:id="@+id/help"
android:icon="@drawable/menu_addnew"
android:title="ÂïÞèåéá" />
</menu>
and my java code is
@Override
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_options_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.new_game:
//newGame();
return true;
case R.id.help:
//showHelp();
return true;
default:
return super.onOptionsItemSelected(item);

Java - Synchronized
Java - Synchronized
Hi i have made a something that extends thread that adds adds an object
that has a IP in it. then i made two instances of this thread and started
them. they use the same list.
I now want to use Synchronized to stop the concurrent update problem. But
its not working and i cant work out why.
My main class:
import java.util.*;
import java.io.*;
import java.net.*;
class ListTest2{
public static LinkedList<Peer> myList = new LinkedList<Peer>();
public static void main(String [] args){
try{
AddIp test1 = new AddIp(myList);
AddIp test2 = new AddIp(myList);
test1.start();
test2.start();
}
catch(Exception e){System.out.println("not working");}
}
}
My thread class:
class AddIp extends Thread{
public static int startIp =0;
List<Peer> myList;
public AddIp(List<Peer> l){
myList = l;
}
public synchronized void run() {
try{
startIp = startIp+50;
int ip = startIp;
InetAddress address = InetAddress.getByName("127.0.0.0");
Peer peer = new Peer(address);
while(ip <startIp+50){
ip++;
address = InetAddress.getByName("127.0.0."+ip);
peer = new Peer(address);
myList.add(peer);
if(myList.indexOf(peer)== (myList.size() -1)){}
else{System.out.println("Lost"+peer.peerIp);}
}
}catch(Exception e){}
}
}
Can anyone help me out here im lost for ideas thanks.

Syntax issue with python dictionary and multiprocessing script
Syntax issue with python dictionary and multiprocessing script
Hi I am trying to be able to start a thread from a dictionary entry using
this code below. The rest of the code in the script is known good and
fully functional. I cam gonna have to be able to choose from a bunch of
different subroutines so I want to remove as much boilerplate as possible
from the code. Thanks guys and gals!!!!
class worker_manager:
i = test_imports()
template('one': i.import_1, 'two': i.import_2);
def __init__(self):
self.children = {}
def generate(self, control_Queue, threadName, runNum):
p = multiprocessing.Process(target=self.template[threadName],
args=(control_Queue, runNum))
self.children[threadName] = p
p.start()
def terminate(self, threadName):
self.children[threadName].join
When I run this code I get this error:
File "dynamicTest1.py", line 53
template('one': i.import_1, 'two': i.import_2);
^
SyntaxError: invalid syntax
Anyone have any advice?

Experiences with ECL (Embeddeed Common Lisp)
Experiences with ECL (Embeddeed Common Lisp)
Waay back (July 2010), the question was asked:
Does anybody here have a experience with Common Lisp as a embedded
language (using ECL)? >If so, how good is ECL compared to Lua?
http://stackoverflow.com/users/388921/linkit
Which went off into how easy or otherwise Lua is. So far as I can see,
no-one addresseed the question about ECL. SO, Does anyone have experience
using ECL, and is it OK. Don't bother with how much you love or hate some
alternative embedded language, please just tell me about ECL. TIA

Regex Matching Unicode Characters acting oddly with different strings
Regex Matching Unicode Characters acting oddly with different strings
Ok, I am doing a unicode regex match on some strings.
These are the strings in question.
\u2018Mummy\u2019 Reboot May Get \u2018Mama\u2019 Director
\u2018Glee\u2019 Star Grant Gustin to Play The Flash in \u2018Arrow\u2019
Season 2
And I am using this regex to parse out the titles surround in unicode quotes.
regex = re.compile("\\u2018[^(?!\\u2018$)]*\\u2019",re.UNICODE)
using regex.findall() returns me
['u2018Mama\\u2019']
and
['u2018Glee\\u2019', 'u2018Arrow\\u2019']
This brings up two questions that I couldn't figure out. why isn't it
returning \u2018, where is the initial \?
Secondly, what is different. I can't see it. Finally, I replaced \u2018
and \u2019 with '. Then using this regex.
re.compile("'[^']*'")
It matches both in both strings. What is the difference here? What am I
missing in the unicode regex?
Thank you in advance.

SVG is not loading properly in Mobile Safari
SVG is not loading properly in Mobile Safari
I was able to get fonts to load in Android but when it came to iOs the
.svg file seems to not load properly.
In iOs, it seems that it is still using the default Apple font for
converting "Shruti" (Gujarati font). This conversion causes issues in font
rendering. Thats why I was resorting to supply the "Shruti" font by using
svg. However its not loading properly.
Here is the definition I am using :
@font-face {
font-family: "Shruti";
src: url('http://www.bhajansangrah.com/shruti.eot?') format('eot'),
url('http://www.bhajansangrah.com/shruti.woff') format('woff'),
url('http://www.bhajansangrah.com/shruti.ttf') format('truetype'),
url('http://www.bhajansangrah.com/shruti.svg#Shruti') format('svg');
} div { font-family: "Shruti", Verdana, Tahoma; }
Here is an example site: http://www.bhajansangrah.com/index.php?title=96
So for example, in line 1 we see that the text should be
"બાદશાહી
ગૌરવ બિરાજે,
ત્રાતાના
લલાટે,"
which appears fine on all browsers, including Android, except for Mobile
Safari (my guess is that its not loading the svg file properly)
In iOs (Mobile safari) it shows up as, incorrectly :

Overwriting class object due to string parsing issue
Overwriting class object due to string parsing issue
I am trying to read a fixed width text file and store each element to a
class object. Each row in the text file needs to be checked for which
parsing action must be performed. Rows 1000 and 1001 each need to be
parsed differently and rows 1002-1004 use the same parsing action. I am
reading the file and parsing correctly, but when I add elements to the
class object the object gets overwritten in each "if" statement. Then when

I am trying to read a fixed width text file and store each element to a
class object. Each row in the text file needs to be checked for which
parsing action must be performed. Rows 1000 and 1001 each need to be
parsed differently and rows 1002-1004 use the same parsing action. I am
reading the file and parsing correctly, but when I add elements to the
class object the object gets overwritten in each "if" statement. Then when
the object is added to a list the list contains empty lines. I feel like I
am taking the wrong approach. I am new to C# and I apologize if this has
been answered, but after many hours of searching I cannot find a solution.

unable to get child element to fadein when hovering over parent element
unable to get child element to fadein when hovering over parent element
I am new to JQuery and am currently attempting to get a child element to
fade in to display product information when the user hovers over the
parent element.
this is as far as I've got with out luck:
jquery:
$('.overlay-wrap').hover(function(){
$('.product-overlay', this).fadeIn(2000, "swing");
},
$('.product-overlay', this).fadeOut("fast");
});
html:
<div class="overlay-wrap">
<div class="product-overlay"><a href="#">Name of the
product</a></div>
</div>
css:
.overlay-wrap{
position:relative;
border:1px solid red;
width:200px;
height:200px;
}
.product-overlay{
position:absolute;
bottom:0px;
left:0px;
background:#000;
opacity:0.5;
padding:5px;
width:100%;
display:none;
}
.product-overlay a{
font-size:12px;
line-height:20px;
}
Heres a simplified JSFiddle of what I have so far.
Why isn't the child element fading in when I hover over the parent element?
Thanks

Chrome: jQuery Height not Setting on First Load
Chrome: jQuery Height not Setting on First Load
I've encountered a strange error ONLY in Chrome where height will not
properly set on load when being set via jQuery. The height will set find
on load when the browser is refreshed, but when you open a new tab or
first navigate to the page, the height is not properly set:
wrong:
right:
Here is my code:
jQuery(document).ready(function ($) {
var $grid = $(".tile-grid"),
$homeGrid = $(".home"),
$boxes = $grid.find("section"),
$window = $(window);
function resizeBoxes() {
var boxWidth = $boxes.first().not(".active").outerWidth();
$boxes.css("height", boxWidth);
}
function main() {
$window.on("resize", function() {
resizeBoxes();
});
resizeBoxes();
}
main();
});
Upon further investigation, I find that the function has been executed,
but that each box has been set to have a height of 9px, which seems to
indicate that an animation may be responsible for this. But when I remove
all animations, I still get the same result...
How do I fix this?

Storyboard returns new instance with old property instances iphone
Storyboard returns new instance with old property instances iphone
So i was working on storyboard and i ran into a corner. I created an int
array int[3] and i set values to 0. Then i changed first value on first
page, and second value on another page. I thought both pages has same
instance of int array but i noticed that the array has same values in both
views and same memory address.
So i made stuff more complicated. I created an NSMutableArray, on
viewDidLoad i set this array to nil, then i alloc and init it. I then add
one object to it. Next page - new array! New memory address, no elements.
So i add one element to this array - bam! Address is now the same as in
old view and there are two elements (old one and new one).
Yes i did release that array on dealloc on old view.
So i created static int, and incremented it in viewDidLoad
static int i = 0; i++;
Every time i open new page, with different memory address i get integer
incremented by one and printed out. This happens on empty project with
nothing altered.
My question: Why do i read in apple docs that storyboard creates new and
unique instance of views and then i see this "old value issue"?
UPDATE
Okay so i declare my array like this:
@property (retain, nonatomic) NSMutableArray *destroyedObjects;
Dealloc method:
- (void)dealloc
{
[_destroyedObjects release];
_destroyedObjects = nil;
[super dealloc];
}
Initialisation of the view itself:
- (DataViewController *)viewControllerAtIndex:(NSUInteger)index
storyboard:(UIStoryboard *)storyboard
{
// Return the data view controller for the given index.
if (([self.pageData count] == 0) || (index >= [self.pageData count])) {
return nil;
}
// Create a new view controller and pass suitable data.
DataViewController *dataViewController = [storyboard
instantiateViewControllerWithIdentifier:@"DataViewController"];
return dataViewController;
}
View did load of this controller:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
_destroyedObjects = nil;
_destroyedObjects = [NSMutableArray new];
}
Somwhere within the code i do this (this is done as soon as button in xib
is pressed):
[_destroyedObjects addObject:[NSNumber numberWithInt:[objectView
typeInteger]]];
How i see that values are bad? This is log when i init the view (NSLog
self) and when i set the value (log self and array):

Efficient way to merge multiple large XML files on android
Efficient way to merge multiple large XML files on android
Use Case: Think of an application that performs a daily backup of your
call log or messages and stores it into an XML file.
Now, I want to implement the ability to merge two or more files and create
one XML file. Some of the entries may be duplicate, some added, some
deleted.
I could create a Map and put all entries into it with "id" being the key
(which will be unique for each row). But this approach may cause memory
issues if the number of rows run into several thousands.
Can anybody suggest a better way of implementing this merge feature?

(which will be unique for each row). But this approach may cause memory
issues if the number of rows run into several thousands.
Can anybody suggest a better way of implementing this merge feature?

overriding Cart.php class doesn't work in prestashop
overriding Cart.php class doesn't work in prestashop
I am try to override the default Cart.php class. I put my Cart.php in
override/classes/Cart.php. but It doesn't make any changes in the output.
<?php
class Cart extends CartCore
{
print_r("sample test override");
die();
}
?>
my cart.php code is like above. Can anyone help me, is there any other
additional steps needed to override?

Retreiving Native Code Architecture from an Android App
Retreiving Native Code Architecture from an Android App
I'm working on an app which determines the native code architecture and
native libraries used by the apps installed on the device. Its similar to
running the following command.
aapt dump badging <file.apk location>
The package manager doesn't provide information about the native code like
this one or the native shared libraries. I can retrieve the native shared
libraries that the target app uses with the following code:
try {
Set<String> libs = new HashSet<String>();
String mapsFile = "/proc/" + android.os.Process.myPid() + "/maps";
BufferedReader reader = new BufferedReader(new FileReader(mapsFile));
String line;
while ((line = reader.readLine()) != null) {
if (line.endsWith(".so")) {
int n = line.lastIndexOf(" ");
libs.add(line.substring(n + 1));
}
}
Log.d("Ldd", libs.size() + " libraries:");
for (String lib : libs) {
Log.d("Ldd", lib);
}
} catch (FileNotFoundException e) {
// Do some error handling...
} catch (IOException e) {
// Do some error handling...
}
All I require is the native code architecture used by the app package. I
want to determine the compatible native code architecture from app
package. Any help?

Why is my ASCII char to int conversion failing?
Why is my ASCII char to int conversion failing?
According to the chart here:
http://www.idautomation.com/barcode-faq/code-128/
This character:
Ë
equates to the value 103.
Yet this code:
string barcode = textBoxRawCode128.Text.Trim();
. . .
int runningTotal = ConvertToASCIIInt(barCode[0]);
. . .
private int ConvertToASCIIInt(char valToConvertToASCII)
{
const int ASCII_ADJUSTMENT_VAL = 32;
return valToConvertToASCII - ASCII_ADJUSTMENT_VAL;
}
...when the value in the textbox and thus of barcode is "ËTry another
string.", thus where barcode[0] is "Ë", returns a value of 171 instead of
103...???
And according to this chart: http://www.adams1.com/128table.html, the
value corresponding to 103 is ‡, but when I set barCode to "‡Try another
string.", the returned value is 8193...??? Curiouser and curiouser...
Note: A related/preliminary post is Is this code for calculating Code128
barcode check digits correct?

Return child class from parent's static method
Return child class from parent's static method
I just learned about this fancy new feature of PHP 5.4. JsonSerializable!
This is perfect for my app.
My app uses DateTime objects, and when I json_encode them, I get the
following (by running json_encode([new DateTime])):
[{"date":"2013-09-11 15:39:22","timezone_type":3,"timezone":"UTC"}]
Depending on what timezone_type is, the timezone value may be different. I
haven't found a good way to parse this object in JavaScript.
So, I decided to create my own DateTime class, and have it serialize to
JSON how I wanted.
class SerialDateTime extends DateTime implements JsonSerializable{
public function jsonSerialize(){
return ['timestamp' => $this->getTimestamp()];
}
}
When I now run json_encode([new SerialDateTime]), I get this:
[{"timestamp":1378914190}]
That's much easier to parse in JavaScript.
So, I figured this was a fine solution, but I discovered a problem. Static
methods! SerialDateTime::createFromFormat returns a DateTime object!
If I do: json_encode([SerialDateTime::createFromFormat('m/d/Y',
'10/31/2011')]), I get:
[{"date":"2011-10-31 15:46:07","timezone_type":3,"timezone":"UTC"}]
Why is this happening? Why doesn't SerialDateTime::createFromFormat return
me a SerialDateTime object?!
How can I fix this, or do I need to override all the static methods from
DateTime in SerialDateTime? If I do that, how would I even make a new
SerialDateTime from the createFromFormat method? How can I "cast" a
DateTime object to SerialDateTime?
I thought of a workaround, but there's got to be a better way:
public static function createFromFormat($f, $t, $tz=NULL){
$dateTime = call_user_func(
array('SerialDateTime', 'parent::createFromFormat'),
$f, $t, $tz
);
$ret = new self();
return $ret->setTimestamp($dateTime->getTimestamp());
}
Could I maybe use __callStatic and return
call_user_func_array(array(__CLASS__ , 'parent::'.__FUNCTION__),
func_get_args()); or something?

Deterministic python generator for K disparate M-sized subsets of a set
Deterministic python generator for K disparate M-sized subsets of a set
I'm looking for an efficient way to generate many M-sized subsets from a
set S, of size N.
Ideally I would like to generate all of these, but because I'm using them
for other computations, this becomes infeasible.
Instead, I would like to generate K disparate subsets of S, such that the
K chosen subsets minimize the sum of the size of the all pairwise
intersections between the K subsets.
In other words If I have K subsets And I take the pairwise intersection of
all of those subsets. And then I sum the size of all of those sets
together. I get as low of a number as I can.
Basically, I want these subsets to be as "far away" from each other was
possible. I've been trying to think of how I would go about doing this,
but I'm drawing a blank.
To simulate it in the meantime I've written this function
def subset_split(full_set, M, K):
np.random.seed(0) # repeatibility
seen = set([])
subset_list = []
for kx in xrange(K):
np.random.shuffle(full_set)
failsafe = 0
while True:
np.random.shuffle(full_set)
subset = tuple(full_set[0:M])
if not subset in seen:
seen.add(subset)
subset_list.append(subset)
break
failsafe += 1
if failsafe > 100:
break
return subset_list
which just generates K random subsets that haven't been seen before. But
this isn't exactly what I want, because I want those K subsets to be
repeatable and to not accidentally be close to each if they don't have to
be.

Calling WCF Service from JavaScript
Calling WCF Service from JavaScript

EmberJS, how to query the model with getter functions?
EmberJS, how to query the model with getter functions?
I don't know if I asked correctly, but instead of having the collection of
data, I would like to compute the data based on parameter. Something like:
var date = new Date();
var events = model.getEvents(date);
{{#each event in events}}
event
{{/each}}
The difference being here that getEvents does both the fetching from
server, plus local computation and transformation before returning the
collection.
