first element to "\0" to clear content of array. Can anyone explain for
me. Thank a lot.

Yii Time Table genaration
Yii Time Table genaration
I am new to yii framework. As a project we do a school information
management system. In that system we have to create a time table.
The time table has 5-days(Monday-friday) as columns and 8 periods as rows.
In a cell there should be two dropdown lists for subject and corresponding
teacher. All together there are 80 dropdown lists.So I have to write code
for all 80 dropdowns.
Is there any way to minimize the code for dropdowns or can anyone suggest
a better way to do this.
(In the beginning of the time table form class is select and according to
that subjects are updated to dropdowns. From the subject can select the
corresponding teacher)

Different text color for each class object?
Different text color for each class object?
I'm making some kind of "game score tracker". Here's how the app currently
works:
User adds players by typing a name into EditText and then clicking ok button.
After the user finished adding new players, he presses "start game" button
and a new activity opens.
Players are added to Parcelable extra and taken to the next activity.
In the next activity, a user has a spinner, EditText and +, - buttons.
After the user selects a certain player from the spinner, types in a
certain score and then either a + or -, a new TextView will appear
containing Player name and score.
Example: If there are 3 Players "James, John and Robert". The user then
adds 5 points to James, 10 points to John and 15 points to Robert. This is
how TextViews will look like:
James 5
John 10
Robert 15
Then if user will do the exactly same thing again, this will happen:
James 5
John 10
Robert 15
James 10
John 20
Robert 30
So as you can see, I don't keep the same TextView for each player but I
keep adding them (I do want that, I want the user to be able to see his
actions, when he clicked - and when +. But is there a way to somehow set a
color for each user? Example: James will be blue, John will be red and
Robert will be green. How do I pre-determine the color of each Player's
TextView?
Player class:
public static class Player implements Parcelable{
String name;
int score;
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(score);
dest.writeString(name);
}
public Player(Parcel source){
score = source.readInt();
name = source.readString();
}
public Player(){
}
public static final Parcelable.Creator<Player> CREATOR = new
Parcelable.Creator<Novaigra.Player>() {
@Override
public Player createFromParcel(Parcel source) {
return new Player(source);
}
@Override
public Player[] newArray(int size) {
return new Player[size];
}
};
}
Can I add some kind of color palette to the activity when players are
being added so that a user can pre-determine a color or something?

Ember.js pushState router takeover Laravel route
Ember.js pushState router takeover Laravel route
I'm developing a Laravel/Ember.js app where Laravel serves a general role
of a backend framework and RESTful data supplier and Ember.js partially
for the client side.
So far it works fine. However I want Ember.js to take control for some of
the sub-urls.
Say I have /members route in Laravel which serves Ember app and I want
sub-consequent URL to take advantage of pushState w/ Ember like so:
/members/add, /members/edit/1 etc.. instead of /members#/add,
/members#/edit/1
With Ember this is easily achieved:
App.Router.reopen({
location: 'history', //instead of 'hash'
rootURL: '/members'
})
and it works fine when I click on the links.
However, when I refresh the page Laravel router kicks in with .htaccess
which tries to serve every url through laravel's index.php in public
folder. Here's Laravel original .htaccess file:
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
I'm no expert in Apache URL rewriting, so what I need to do is tell
.htaccess to rewrite everything that follows /members (/members/add,
/members/view etc..) back to /members route so Ember.js would take over
and redirect appropriately.
I was trying to do something like this, but it didn't work:
<IfModule mod_rewrite.c>
Options -MultiViews
Options +FollowSymLinks
IndexIgnore */*
RewriteEngine On
RewriteCond %{REQUEST_URI} /members
RewriteRule (.*) members
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
Any help on this topic of url rewriting is appreciated. Thanks!

Can I use ArrayList in a class which extends Thread?
Can I use ArrayList in a class which extends Thread?
Is it possible to use an ArrayList within a class that extends Thread? I
have written some code to read from Bluetooth serial which was working,
but I've added an ArrayList to keep track of what I'm reading. However I'm
getting NullPointException on any line that accesses results. I know that
ArrayList is not thread safe (although I may not understand fully what
that means) so I may be trying to do impossible things but I thought I
would check with the experts as ArrayLists are otherwise very easy to work
with.

Create Xcode project for existing cross-platform file structure
Create Xcode project for existing cross-platform file structure
I am creating a C++ static library which is meant to be compilable on
Windows, OSX/iOS, or Linux. At the moment, the existing directory
structure is:
LibraryRoot
.git - git repository
Core - core OS independent source code
OSX - OSX specific code, including Xcode project files
Windows - Windows specific code, including developer studio project
files
Linux - Linux stuff
I dont understand how to create the project using this file structure
within Xcode. It seems that Xcode wants to create a directory with the
project name and put a new repository and project files inside, which is
not what I want here. Also I'm not sure how to make Xcode recognize the
git repository which is above the directory which is intended to host the
Xcode project files. I don't need to create any special makefile or rules
outside of the Xcode project file.
Is doing it this way possible with Xcode?

How to change the default blue color?
I can fetch color from database. But can't use inline css to apply color

Using angular ng-repeat properly
Using angular ng-repeat properly
So i'm fairly new to angular and what i'm trying to do is take a json
collection that is obtained from a RESTful call and loop through each one
to display their value while associating its designated id in a href.
below you will find what I have tried:
<div class="span2">
<!--Sidebar content-->
Search: <input ng-model="query">
Sort by:
<select ng-model="orderProp">
<option value="name">Alphabetical</option>
<!--option value="age">Newest</option>
<option value="-age">Oldest</option-->
</select>
</div>
<div class="span10">
<!--Body content-->
<ul class="documents">
<li ng-repeat="document in documents | orderBy:orderProp"
class="thumbnail">
<a
href="#/rest/{{document.document_id}}">{{document.title}}</a>
</li>
</ul>
<pre>{{ documents | json }}</pre>
</div>
the Shttp call:
function DocListCtrl($scope, $http)
{
console.log('getting documents data');
$http.get('/*RESTful call here*/').success(function(data)
{
$scope.documents = data;
});
$scope.orderProp = 'name';
}
when I run the page i get my list no problem using the
<pre>{{ documents | json }}</pre>
but the ng-repeat fails to implement.
What exactly am I doing incorrectly with the ng-repeat call that fails to
list my data the way i wish?
Thanks for the help

UITextView Attributed Text
UITextView Attributed Text
I have a UITextView I want to apply attributes to. It can hold 5
characters per line. When I set the attributedText to my
NSMutableAttributedString, spaces within the string are removed. For
example:
NSMutableAttributedString *moreThan5spaces = [[NSMutableAttributedString
alloc] initWithString:@" AAA"]; //7 spaces and then text
self.textView.attributedText = moreThan5spaces;
When I do this, the text "AAA" should appear on the 2nd line, starting
with 2 spaces in front of it. I will use underscores to represent space in
this example:
//I want this:
_____
__AAA
//But I get this:
_____
AAA
When the characters wrap to a new line, spaces are removed. How can I
prevent this?
I have a UITextView I want to apply attributes to. It can hold 5
characters per line. When I set the attributedText to my
NSMutableAttributedString, spaces within the string are removed. For
example:
NSMutableAttributedString *moreThan5spaces = [[NSMutableAttributedString
alloc] initWithString:@" AAA"]; //7 spaces and then text
self.textView.attributedText = moreThan5spaces;

How does SLComposeViewController display the displaying viewController in background?
How does SLComposeViewController display the displaying viewController in
background?
I thought if we display something modally, the viewController in
background will be completely filled.
Yet SLComposeViewController did it differently. We can still see the
viewController in background partially.
How did they do so?
Is this new in iOS 6?

Pagination having issues with page id
Pagination having issues with page id
If i have 10 data in page=1 in pagination,another page having i.e page=2
having another 10 data.and after that page=3 doesn't contain any data.if i
select previous button then that page goes in page-1,page=-2.....and if i
press next button,it will also going on like page=2,page=3 and so on.So
how to disable prev and next button if the record is no longer available

PHP /or/ PYTHON : How to code a script to get e-mails of top 1 mil web

You are about to be provided with information to
start your own Google.
Some people posted comments and said this can not
be done because google has 1 million servers and we do not.
The truth is, google has those many servers for trolling
purposes (e.g. google +, google finance, youtube the bandwidth consuming
no-profit making web site, etc ).
all for trolling purposes.
if you wanted to start your own search engine...
you need to know few things.
1: you need to know how beautiful mysql is.
2: you need to not listen to people that tell you to use a framework
with python, and simply use mod-wsgi.
3: you need to cache popular searches when your search engine is running.
4: you need to connect numbers to words. maybe even something like..
numbers to numbers to words.
in other words let's say in the past 24 hours people searched for
some phrases over and over again.. you cache those and assign numbers
to them, this way you are matching numbers with numbers in mysql.
not words with words.
in other words let's say google uses 1/2 their servers for trolling
and 1/2 for search engine.
we need technology and ideas so that you can run a search engine
on 1 or 2 dedicated servers that cost no more than $100/month each.
once you make money, you can begin buying more and more servers.
after you make lots of money.. you probably gonna turn into a troll
too like google inc.
because god is brutal.
god is void-state
it keeps singing you songs when you are sleeping and says
"nothing matters, there is simply no meaning"
but of course to start this search engine, you need a jump start.
if you notice google constantly links to other web sites with a
trackable way when people click on search results.
this means google knows which web sites are becoming popular
are popular, etc. they can see what is rising before it rises.
it's like being able to see the future.
the computer tells them " you better get in touch with this guy
before he becomes rich and becomes un-stopable "
sometimes they send cops onto people. etc.
AMAZON INC however..
will provide you with the top 1 million web sites in the world.
updated daily in a csv file.
downloadable at alexa.com
simply click on 'top sites' and then you will see the downloadable
file on the right side.
everyday they update it. and it is being given away for free.
google would never do this.
amazon does this.
this list you can use to ensure you show the top sites first in your
search engine .
this makes your search engine look 'credible'
in other words as you start making money, you first display things
in a "Generic" way but at the same time not in a "questionable" way
by displaying them based on "rank"
of course amazon only gives you URLS of the web sites.
you need to grab the title and etc from the web sites.
the truth is, to get started you do not need everything from web sites.
a title and some tags is all you need.
simple.
basic.
functional
will get peoples attention.
i always ask questions on SO but most questions get deleted. here's
something that did not get deleted..
How do I ensure that re.findall() stops at the right place?
use python, skrew php, php is no good.
do not use python frameworks, it's all lies and b.s. use mod-wsgi
use memcache to cache the templates and thus no need for a template engine.
always look at russian dedicated servers, and so on.
do not put your trust in america.
it has all turned into a mafia.
google can file a report, fbi can send cops onto you, and next thing you know
they frame you as a criminal, thug, mentally ill, bipolar, peadophile, and
so on.
all you can do is bleed to death behind bars.
do not give into the lies of AMERICA.
find russian dedicated servers.
i tried signing up with pw-service.com but i couldn't do it due to
restrictions with their russian payment systems and so on..
again, amazon's web site alexa.com provides you with downloadable
top 1 mil web sites in the form of a csv file.
use it.
again, do not give into python programmers suggesting frameworks for python.
it's all b.s. use mod_wsgi with memcache.
again, american corporations can ruin you with lies and all you can do is
bleed to death behind bars
again, a basic search engine needs : url, title, tags, and popular searches
can be "cached" and words can be connected to "numbers" within the mysql.
mysql has capabilities to cache things as well.
cache once, cache twice, and you will not need 1 million servers in order
to troll.
if you need some xdotool commands to deal with people calling you a troll
here it is;
xdotool key ctrl+c
a=`xclip -o`
b=`echo "$a" | sed -e 's/^ *//g' -e 's/ *$//g'`
xdotool key Tab Tab Tab Return
xdotool type '@'
xdotool type "$b"
xdotool type --clearmodifiers ', there can not be such thing as a `troll`
unless compared to a stationary point, if you are complaining, you are not
stationary. which means you are the one that is trolling.'
xdotool key Tab Return
create an application launcher on your gnome-panel, and then select the
username in the comments section that called you a 'troll' and click the
shortcut on the gnome-panel.
it will copy the selected username to the clipboard and then hit TAB TAB
TAB RETURN
which opens the comment typing box. and then it will type @ + username +
comma, and then the rest. ..........................................

is there any account recovery gem for ruby on rails that uses SMS?
is there any account recovery gem for ruby on rails that uses SMS?
I was wondering if there was any account recovery gem for a ruby on rails
password allowing the app to send the user to his sms a pin to reset their
password in the event the user forgets it? Googled but didn't see
anything, figured I would ask here in case my google search string was
just poorly written.

List directory files in a DataGrid
List directory files in a DataGrid
I have searched many topics and can't find an answer on using the WPF
DataGrid to list file name contents from a directory. I am able to output
the contents in a ListBox but have no idea how to add items to a Column in
DataGrid.
This works for a ListBox
string path = "C:";
object[] AllFiles = new DirectoryInfo(path).GetFiles().ToArray();
foreach (object o in AllFiles)
{
listbox.Items.Add(o.ToString());
}
How can I do the same with a DataGrid? Or atleast place strings from an
array into a DataGrid Column?

Files saved with Ubuntu is not visible in Windows 8
I have dual booted my laptop with ubuntu 12.10 and windows 8. When I
download some file via ubuntu (e.g a pdf) and save it on a windows
partition(NTFS), I do not see it through windows 8. Even when I set to
view hidden files, the files do not appear. But when I boot with Ubuntu I
see the file is there.
What is the issue here. This is not a very good experience for me. Please
let me know how to fix the issue.

Decompose floating-point number
Decompose floating-point number
Given a floating-point number, I would like to separate it into a sum of
parts, each with a given number of bits. For example, given 3.1415926535
and told to separate it into base-10 parts of 4 digits each, it would
return 3.141 + 5.926E-3 + 5.350E-8. Actually, I want to separate a double
(which has 52 bits of precision) into three parts with 18 bits of
precision each, but it was easier to explain with a base-10 example. I am
not necessarily averse to tricks that use the internal representation of a
standard double-precision IEEE float, but I would really prefer a solution
that stayed purely in the floating point realm so as to avoid any issues
with endian-dependency or non-standard floating point representations.
No, this is not a homework problem, and, yes, this has a practical use. If
you want to ensure that floating point multiplications are exact, you need
to make sure that any two numbers you multiply will never have more than
half the digits that you have space for in your floating point type.
Starting this this kind of decomposition, then multiplying all the parts
and convolving, is one way to do that. Yes, I could also use an
arbitrary-precision floating-point library, but this approach is likely to
be faster when only a few parts are involved, and it will definitely be
lighter-weight.

How to make the whole record readonly in openerp7
How to make the whole record readonly in openerp7
I know to make a field readonly with the "readonly" attribute. Is it
possible to make the entire record readonly. That means that all field in
a form should be readonly on a condition.
One insignificant way i found is to make this
attrs="{'readonly':[('state','=','close')]}" in all the fileds present in
the form.
<field name="responsible_id" class="oe_inline" attrs="{'readonly':
<field name="type" attrs="{ 'readonly':[('state','=','close')]}"
class="oe_inline"/>
<field name="send_response"
attrs="{'readonly':[('state','=','close')]}"/>[('state','=','close')]}"/>
However i don't think this be the right one. I expect some way to put
readonly attribut common for the form. Kindly suggest.
In my example, People can view all the records and edit only their own
records.
Thank You.

Developing ASP.Net with reportviewer / wizard - missing UI options
Developing ASP.Net with reportviewer / wizard - missing UI options
I'm new to C# .net web development and I'm trying to learn how to create a
simple reporting site from online walkthroughs etc. I'm a SQL Dev by
trade... So I'm probably missing something basic.
Here's the instructions I'm working from
(http://msdn.microsoft.com/en-us/library/ms252123.aspx): 1. Make sure that
the top-level Web site is selected in Solution Explorer. 2. Right-click on
the Web site and select Add New Item. 3. In the Add New Item dialog box,
select Report Wizard, enter a name for the report file, and then click
Add.
The problem is, "Report Wizard" is not on the list of installed items in
the add item dialog box. In fact there is nothing report related on the
list.
I'm using Microsoft Visual Studio Express for Web, which AFIK includes the
correct report components. I created the project as a website (File -> New
Website, ASP.Net Website)
I bet I'm missing something that will earn me a face palm, but I've
searched high up and low down and wasted the best part of a day. I'd
appreciate any help! Thanks

Using box-sizing to create an inside border
Using box-sizing to create an inside border
I want to create an HTML table where each cell is clickable, and clicking
on a cell adds a border to the single div within the cell. I want that
div's border to exist entirely within the existing confines of the td that
contains it, without resizing the table or its cells at all. I can't seem
to make this happen correctly.
This previous question seems to address the same issue and points to some
articles about the box-sizing CSS options. I have a fiddle where I tried
to implement this without success: http://jsfiddle.net/YsAGh/3/.
* {
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
}
<table>
<tr>
<td><div>1</div></td>
<td><div>2</div></td>
<td><div>3</div></td>
</tr>
....
</table>
Here's what currently happens. The border causes the containing td to grow
to accommodate the div's border.
How can I add the border to the div without it affecting the containing
table?

contains it, without resizing the table or its cells at all. I can't seem
to make this happen correctly.
This previous question seems to address the same issue and points to some
articles about the box-sizing CSS options. I have a fiddle where I tried
to implement this without success: http://jsfiddle.net/YsAGh/3/.
* {
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
}
<table>
<tr>
<td><div>1</div></td>
<td><div>2</div></td>
<td><div>3</div></td>
</tr>
....
</table>
Here's what currently happens. The border causes the containing td to grow
to accommodate the div's border.
How can I add the border to the div without it affecting the containing
table?

Break Batch Script Execution during Pause
Break Batch Script Execution during Pause
I'm developing a complex, long-running batch script, and came upon a
little issue when debugging. I have a command-line window open to the root
path of the script, so I can type myscript.bat to fire it off for testing.
I am using PAUSE commands between statements to watch the behavior of the
script. However, I discovered that typing CTRL+C during a PAUSE command to
cancel execution is simply interpreted as a key to continue execution,
rather than breaking the script as intended.
I know I can simply kill/close the command window, but it's a little
annoying to navigate back to the correct path in a new command-window
every time. Is there a way to properly break a batch script's execution
easily while it is currently in a PAUSE?
Edit: It looks like PAUSE works fine in simple scripts, as indicated by
@dbenham. However, if you have multiple PAUSE statements nested inside of
a FOR iteration, then you can't break in the middle of the FOR iteration -
only at the end. Here is a sample script that demonstrates the issue:
@echo off
for /l %%y in (2008, 1, 2013) do (
echo 1
pause
echo 2
pause
echo 3
pause
echo 4
pause
echo 5
pause
)
If you try to terminate any of the first four PAUSE statements, you will
find that your terminate command is ignored and execution continues
anyway. But once you reach the end, to the fifth PAUSE, you do get the
terminate prompt (in the example output below, I was pressing CTRL+C at
every prompt):
Z:\>test
1
Press any key to continue . . .
2
Press any key to continue . . .
3
Press any key to continue . . .
4
Press any key to continue . . .
5
Press any key to continue . . .

Best way to update Tomcat 7 of Ubuntu Server 12.04
Best way to update Tomcat 7 of Ubuntu Server 12.04
Ubuntu Server 12.04 repository has Tomcat 7 in version 7.0.26. I prefer
using this installation because it creates the user, init script and log
rotation configuration.
What would you suggest to keep it updated with the latest version:
download from tomcat.apache.org, copy the jars and diff the configuration
files or use the Debian repository?
Thanks, Philip

Can the following proof concerning irrationality of square roots be improved?
Can the following proof concerning irrationality of square roots be improved?
Is the following proof too lengthy? Can it be made shorter, yet still be
elaborate?
Prove that there is no rational number whose square is $\sqrt{12}$.
Suppose $p, q \in \Bbb Q$. Of course, both elements cannot both be even if
they are expressible in a rational field. Suppose there was a rational
number such that $$({p \over q})^2 = 12$$
then $p^2 = 12q^2$. This implies $p^2$ (and therefore $p$) is even since
an odd number multiplied by itself gives an odd number. Since any number
multiplied by an even number is even, this implies the RHS is even.
Thus, the RHS must be divisible by 4, so the result is $p^2 = 3q^2$. This
implies that there is no rational whose square is $\sqrt{3}$, as the RHS
isn't divisible by 4 when q is odd. Since $4\sqrt{3}$ yields an irrational
number, there is no rational whose square is 12. QED.

html form enctype=multipart/form-data
Hi I'm trying to create a form that will load images following some web
examples but I can't get the images to load. I'm working on my personal
fedora box running apache. Is there some settings that I have to do
differently with Apache? Here's my form script that should be uploading
image:
<form name ="input" enctype="multipart/form-data" action =
"addPhotograph.php" method = "get">
<table>
<tr>
<th>Title:</th> <td><input type="text" name
="photoname"></td>
</tr>
<tr>
<th>Photograph:</th> <td><input type="file" id="file"
name="file" accept="image/*"></td>
</tr>
<tr>
<th>Photographer:</th><td><input type=""
name="photographer"></td>
</tr>
<tr>
<th>Genre:</th><td><input type = "" name="genre"></td>
</tr>
<table>
<input type="submit" value = "Submit">
</form>
And Here's my PHP script:
<?php
$uploaddir = '/var/www/html/photodb';
$uploadfile = $uploaddir . basename($_FILES['file']['name']);
echo '<pre>';
if (move_uploaded_file($_FILES['file']['name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.\n";
} else {
echo "Possible file upload attack!\n";
}
echo 'Here is some more debugging info:';
print_r($_FILES);
print "</pre>";
?>
When I add an image through the form the php form fails saying "Possible
file upload attack!" I guess this means either the file was not able to be
moved or the file was not uploaded?
I'm doing this for my college assignment any response or other idea is
dearly appreciated :).

and then open up a page listing all the notices with in that board
(similar to subreddits in reddit).

Also, in the error traceback, the board_name variable value is preceded by
a 'u' before the quoted string, e.g:

If I'm getting the url pattern wrong or haven't explained the problem well
enough, please let me know as any help would be greatly appreciated.

A few notes:
The code seems to not be reachable, as there is an exit statement before

int32 is typedef'ed but you shouldn't care too much about it.
This piece of code is from a language's runtime in a compiler, for anyone

Querying an array field that contains hashes in mongoDB?
Querying an array field that contains hashes in mongoDB?
I have a problem in fetching the data from database. I have a array type
column in mongodb database, in which i am saving hash type data in each
array index. I have to get data on the basis of that hash match from the
data base.
My data in database is saving like this
{
"_id" : ObjectId("521603970ff5fa4b47000018"),
"message_text" : "#cricket #badminton #sachin #tendulkar #ibl

The query column is the array type column.
During searching i make a hash again form matching it like follows

How to store dynamically built lists in database in a natural way so that they are just ready for reads?
How to store dynamically built lists in database in a natural way so that
they are just ready for reads?
For a social network site, I need to store dynamic lists for each entity(&
millions of such entities) which are:
frequently appended to
frequently read
sometimes reduced
lists are keyed by primary key
Need to consider for easy scaling & administration by small team &
starting out with just 1 or 2 medium sized VPS(s) & adding more as data &
load grows.
I'm already storing some other type of data in mysql but for these storing
dynamic lists, MySQL is not anyway ideal. I know that I could store my
data in an RDBMS in such a way that using JOIN(s) I'll be able to generate
those lists but I'm trying to avoid JOINs altogether to make the system
easy scalable & instead store prepared lists in a natural way. Since lists
are of variable length, storing list items as columns within a row is not
possible.
So how do I solve this ? Should I use another database for this data,
probably the one that provide adding variable no of columns to keyed by a
primary key. Something like Cassandra ?

Drupal 7 content without article tag
Drupal 7 content without article tag
I would like to use drupal, but after searching for a long time I cannot
find anything that allows me to put the main content outside of an article
tag. I really don't like putting php into a wiki text box and would like
to know if there is a way to make the main content a div or something.

I tried my questions's answers on stackoverflow having same problem but

way
1) i checked whether json content encoding is correct or not
obj.info()

2) i decoded the response_str in utf-8
json.loads(response_str).decode("utf-8")

Parse error on line 1:

surprisingly following link of rescued my sleep. JSONDecodeError:

Basically i was using exact code to get json response in both cases , but
whats wrong with the second json response, only difference i noticed that
the structure of second json response was different from first one.

Network traffic filtering by developing a Linux kernel module
Network traffic filtering by developing a Linux kernel module
I am trying to make my own network traffic filter. To achieve this, I am
building a Linux kernel module using netfilter and getting access to all
the network packets. In order to filter these captured network packets I
need to use a separate program (*filter_prog*) which I have developed. The
output of this *filter_prog* determines whether the packet will be allowed
to go through or not.
My query is, how can I use this *filter_prog* in a kernel module?
Secondly, is the approach correct? or there is an alternative approach
which is more easy to implement and is fast.
Thanks for any help.

Link only available for my own app
I upload some data to my server with my app. I send the data to a PHP-File
on the server and this PHP write the data in my database. This works fine.
But currently I have the link to this PHP unsave in my Android-code.
Is there a possibility to save this link or make my PHP only for my app
available?

Android - can no longer see google Maps after going to production
Android - can no longer see google Maps after going to production
All,
I have been banging my head over this one for a few weeks now. I got
google maps v2 setup for debug following all of their directions. I got my
debug key based on the debug.keystore and everything worked great.
I was then releasing my application to the Google Play Store and followed
the instructions on how to generate my release key and I generated my
Google API Key using the Sha1 of the release key as the instructions
state.
I released my application to the store and everything works great. Here is
the problem though, I can no longer get the maps to show up even when
switching back to the debug API key.
Currently to debug I have been releasing a build to Beta, waiting 3 hours,
and then fixing accordingly. Luckily my map work has stabilized on this
application but I would still like to understand what is going on.
Any ideas anyone?

Derivative of logarithmic function
Derivative of logarithmic function
If the function $f(x)=\log_{2x}x^2$ is given, what is $f'(4)$?
I tried to use the formula for derivative of logarithm but here the base
is $2x$, so it made me confused.
Note that the answer is $1/(18\ln 2)$.

Django Session Not Working - New Cart For Each Item
Django Session Not Working - New Cart For Each Item
I'm working on a simple e-commerce site (following the Coding for
Entrepreneurs course). I have view for the cart (below). I'm having a
problem with the session - each time I add an item to the cart it gets
added to a new cart, when they should be all added to the same cart for
that session. I'm new to Django, and can't see where I'm going wrong here.
Any advice on how to get each item added to go into the same cart would be
much appreciated.

Opening port so that pgAdmin on Windows 7 can connect to PostgreSQL on Debian on VirtualBox
Opening port so that pgAdmin on Windows 7 can connect to PostgreSQL on
Debian on VirtualBox
Hello all :) I'm a having a little trouble connecting this.
On Windows 7 about my Debian 6 on VitualBox configured with Host-only
Adapter:
>nmap -T4 -A -v 192.168.56.1
[...]
5432/tcp unknown postgresql
On the Debian, PostgreSQl is listening:
>netstat -tulpn
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 2432/postgres
tcp6 0 0 :::5432 :::* LISTEN 2432/postgres
.. and the port is opened
>iptables -nL
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0./0 tcp dpt:5432
.. and Postgres is accepting all the connections in postgresql.conf
listen-addresses = '*'
port = 5432
In Windows I have this error message from pdAdmin:
Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "192.168.56.1" and accepting TCP/IP
connections on port 5432?
If you encounter this message, please check if the server you're trying
to contact is actually running PostgreSQL on the given port.
Test if you have network connectivity from your client to the server
host using ping or equivalent tools. Is your network / VPN / SSH tunnel /
firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available
IP addresses on the server machine initially. In order to access
the server over the network, you need to enable listening on the
address first.
For PostgreSQL servers starting with version 8.0, this is controlled
using the "listen_addresses" parameter in the postgresql.conf file.
Here, you can enter a list of IP addresses the server should listen
on, or simply use '*' to listen on all available IP addresses. For
earlier servers (Version 7.3 or 7.4), you'll need to set the
"tcpip_socket" parameter to 'true'.
You can use the postgresql.conf editor that is built into pgAdmin III
to edit the postgresql.conf configuration file. After changing this
file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error
message, it's still unlikely that you encounter a fatal PostgreSQL
misbehaviour. You probably have some low level network connectivity
problems (e.g. firewall configuration). Please check this thoroughly
before reporting a bug to the PostgreSQL community.
Best regards

Hi All, I have this select query above using UNION ALL. There is a column
called Value and VariableID in tmp_datasets table. I need to create 2
separate columns and name them val1 for variableID is 1 and val2 if
variableID is 4. If i use UNION ALL it works it creates 2000 records with
the first 1000 as val1 records and next 1000 as val2 records but does not
separate out into 2 sep columns. How do I sep this value column in 2 sep
columns as stated above.

Is ARM supported on WinPhone8 at all?
Is ARM supported on WinPhone8 at all?
I'm facing a weird issue, somewhat similar to this. I have a Windows Phone
8 native DLL project, mostly C++ but with an ARM assembly source in it.
The source is in ARM mode (i. e. not Thumb). C++ is compiled to Thumb.
The app crashes when C++ tries to call into an assembly routine. The call
command in the disassembly is BLX with an immediate offset - it's supposed
to switch mode back to ARM, unconditionally, but somehow it doesn't.
I have the details of the exception. The exception code is 0xc000001d
(invalid operation), and the value of the PC in the crash context struct
is 0x696d5985. That's impossible in either mode - it's misaligned, bit
zero is one. The BLX instruction goes 1b f0 0c eb - if you decipher,
that's a two-part Thumb-style BLX all right, with a 4-aligned
displacement. The T flag in the crash context is SET (CPSR=0x60000010).
I don't have a device, but the crash log from a beta tester is pretty
conclusive. I have a debug log record right before the call into assembly.
Then the crash.

arm-linux-gnueabi compiler options
arm-linux-gnueabi compiler options
I am using, arm-linux-gnueabi-gcc to compile C programs for ARM processor
in Linux. However, I am not sure what is the default ARM mode for which it
compiles.
For example, for the C code:
test.c
unsigned int main()
{
return 0x1ffff;
}
arm-linux-gnueabi-gcc -o test test.c
now, when I look at the disassembly of main() function with objdump, I can
see:
arm-linux-gnueabi-objdump -d test
<main>:
push {r7}
add r7, sp, #0
movw r3, #65535 ; 0xffff
movt r3, #1
mov r0, r3
mov sp, r7
pop {r7}
bx lr
it appears that this is disassembly for Thumb mode of ARM (because of the
push instruction).
How can I display the disassembly as follows:
.sect ".text"
.global _fn
_fn: MOVW A1,#65535
MOVT A1,#1
BX LR
or this
.sect ".text"
.global _fn
_fn: LDR A1, CON1
BX LR
.sect ".text"
.align 4
CON1: .word 0x1ffff
I saw this example here:
http://e2e.ti.com/support/development_tools/compiler/f/343/t/40580.aspx
however, I am unable to view the disassembly the way it is displayed there.
Thanks.

C function headers location: .h or .c?
C function headers location: .h or .c?
Suppose we have function (external only considered here) int foo(int a,
char *b), normally there will be a header that goes with it documenting
what the function does, what each parameter and return value does, etc.
It'll probably be in doxygen format too. My habit is that such header
should go into .h files because that's where the interface is defined and
reader should have all the information in that place. But a lot of people
keep such headers in C file where the actual implimentation goes. I've
seen this in the Linux kernel code also. So was I wrong? Which would you
prefer?

Ember.js ember-model leak issue?
Ember.js ember-model leak issue?
While working on a simple gallery app I realized that my ember app is
slowly eating up memory.
I created a very simple app to demonstrate the issue: index.html app.js
test.js.
Test setup:
Test 1 enters a route and then returns back: Link to Test 1
Test 2 repeats Test 1 100 times. Link to Test 2
From what I can see via Chrome->Profile->Snapshot Test 2 consumes
significantly more memory then Test 1.
Can somebody help me understand what's causing that issue?

How can I implement a two-way bound ComboBox with an "Add New" option?
How can I implement a two-way bound ComboBox with an "Add New" option?
I have a ComboBox that I would like to bind to a property on my class.
However, I would like to intercept the binding process when the first item
in my ComboBox is selected.
The reason is because I have populated my ComboBox with a list of
selectable values. However, I would like for my first item in the list to
be an "Add New..." option. When the user selects "Add New...", I want to
display a new record entry screen that the user can use to add an
additional option to the ComboBox. Once the user creates the new record,
the record will be selected from within my ComboBox.
I imagine this is a scenario that has been encountered numerous times
before. Basically, I want to databind a ComboBox but give my user's the
ability to add options and update the list within the ComboBox.
What is the correct way to do this?

Getting number of bytes of a bitmap
Getting number of bytes of a bitmap
Goal is to show progress of jpeg encoding from bitmap. I have couple of
bitmaps that need to be encoded. So I get the total number of bytes as was
suggested here:
for (var i:int = 0; i < bitmaps.length; i++)
{
bmp = bitmaps[eobj.currentImage];
total_bytes += bmp.getPixels(bmp.rect).length;
}
Then I'm trying to show progress when doing asychronous encoding. I get a
ProgressEvent which gives me bytesLoaded. So I calculate the progress like
so:
total_loaded_bytes += event.bytesLoaded;
var percentage:int = ((total_loaded_bytes / total_bytes) * 100);
However, total_bytes does not add up to total bytes loaded. Total bytes
loaded is way highter.

Difference Between controller and controller.content
Difference Between controller and controller.content
I have an ArrayController and was using {{#each item in controller}} to
iterate over the items in the controller. This was working fine while
using the same controller however after switching controllers I ran into
some weird behavior which stopped the items to being rerendered. Switching
to {{#each item in controller.content}} solved this problem. However I am
not sure how this even happened.
What's the difference between controller and controller.content in an each
expression (or any where else).

Why is textFieldwithPlaceHolderText undefined for one view controller that conforms to UITextFieldDelegate?
Why is textFieldwithPlaceHolderText undefined for one view controller that
conforms to UITextFieldDelegate?
I have two UIViewController sublcasses, both of them conform to the
UITextFieldDelegate protocol. IOW, I have these classes.
# MyVC1.h

# MyVC1.m
@interface MyVC1 () {
// Private variable, so not a property
UITextField *_myTextField;
}
@end
@implementation MyVC1

{
_myTextField = [self textFieldwithPlaceHolderText:@"*Text"];
}
@end
SAME CODE for MyVC2 class, except of course the class name.
However, and this is the strange part, my code compiles for MyVC1, but NOT
for MyVC2. For MyVC2, compiler says "No visible @interface for "MyVC2"
declares the selector "textFieldwithPlaceHolderText". What am I missing
for MyVC2? I've double- and triple-checked!

Audio driver ctoss2k.sys is causing excessive DPC lag and music playback
is not smooth. How can I solve it?
My audio card is an Auzentech x-fi prelude and I have the latest drivers
installed, on windows 7 64 bit. Running a trace showed that ctoss2k, it's
driver, was causing the most latency by an order of magnitude, which
apparently is causing my audio to occasionally skip and stutter.
Is there any combination of card settings to change/enable/disable,
changing the sample rate etc, that would solve the problem? And otherwise,
are there any third party drivers that would fix the issue?

What is the hyperplane bundle (as defined in Fulton's *Young Tableaux*)?
What is the hyperplane bundle (as defined in Fulton's *Young Tableaux*)?
On page 142 of Fulton's Young tableaux, he says that on any projective
space $\Bbb{P}^\ast(V)$ there is a hyperplane line bundle $\mathcal{O}(1)$
described by a quotient line $ V \to L$ whose fiber over a point is the
line $L$. What exactly does this mean?
From what I understand of the hyperplane bundle, it is the bundle over
$\Bbb{P}^n$ whose the total space is constructed from specifying the
transition functions
$$\begin{eqnarray*} \varphi_{ij} : &U_i \cap U_j& \to \Bbb{A}^1 \\
&(x_0,\ldots,x_n)& \mapsto \frac{x_i}{x_j}\end{eqnarray*}$$
where $U_i,U_j$ are the standard affine covers of $\Bbb{P}^n$. More
specifically, the total space $E$ is the disjoint union $\bigsqcup U_i
\times \Bbb{A}^1$ modulo the equivalence relation $(j,u,a) \sim
(i,u,\varphi_{ij}(u)(a))$. How does this construction agree with what
Fulton is saying (and what is he really saying)?

None, Some and conditionnal treatments
None, Some and conditionnal treatments
I would like to get this thing:
a variable named abc must be None, except if the result of complicated
treatments is true. I wrote a beginning of answer but it doesn't work:
def abc={
None
copie.getRoot().asInstanceOf[DefaultMutableTreeNode].children() foreach ({
site => <...more things after...>
}
in the you can find the result e.g. Some(site)
but the compiler does not accept this order, I mean "None" followed by
some conditions eventually finishing by Some(xxx). and if I put "None"
after the conditions, the result will always be "None" of course, and it's
not what is expected.
can you tell me if this way can work, and how? Or otherwise how can I
proceed?
thanks

Issue with JS and dynamic select form fields -
Issue with JS and dynamic select form fields -
Currently I have a select form field (which I will refer to as state)
which needs to dynamically populate another select form field (which I
will refer to as school). The use case is that the user selects their
state, and based on that state chosen, they are presented with selects for
a school that populate that state.
The states are read from a flat file (data.php) and stored in $state_arr,
and the schools are read from the same flat file, stored in $stateSchool.
To complicate the matter, the select fields are heavily stylized.
The following code populates the state select based on the flat file:
<div id="stateField" class="selectStyled">
<select class="singleField styled" name="kp_state"
id="kp_state">
<option value="default">STATE</option>
<?
foreach ( $state_arr as $state_abv )
{
echo '<option value="' . $state_abv .
'">' . $state_abv . '</option>';
}
?>
</select>
</div><!-- //selectStyled -->
This part works fine… and appropriately populates the state field. The
issue is that when the user selects their state, it's not changing the
school select form. The code I'm using for the school select form is as
follows:
<div id="schoolField" class="selectStyled">
<select class="longField styled" name="kp_school1"
id="kp_school1">
<option value="default">CURRENT SCHOOL</option>
</select>
</div><!-- //selectStyled -->
The JS that I'm using to try to get the above schoolField to populate is
as follows:
<script>
var kp_dropdownOpts = {}
$(function(){
<?php
foreach ($state_arr as $sa)
{
if ( isset($stateSchool[$sa]) )
{
foreach ($stateSchool[$sa] as $value)
{
?>
window.kp_dropdownOpts.<?php echo $sa; ?> += '<option
value="<?php echo $value; ?>"</option>';
<?php
}
}
}
?>
$('#kp_state').change(function(){
var state = $(this).val();
var len = 0;
for (var o in window.kp_dropdownOpts[state]) {
len++;
}
if(len > 0){
var newDrop = window.kp_dropdownOpts[state];
$('#kp_school1').html(newDrop.replace('undefined', ''));
}
else {
$('#kp_school1').html('<option value="default">No Schools
Listed For Your Area</option>');
}
});
});
</script>
In addition, I have the following code which styles the drop downs:
// Iterate over each select element
function custom_select()
{
if($('select').length)
{
$('select').not('.s-hidden').each(function() {
// Cache the number of options
var $this = $(this),
numberOfOptions = $(this).children('option').length;
// Hides the select element
$this.addClass('s-hidden');
// Wrap the select element in a div
$this.wrap('<div class="select"></div>');
// Insert a styled div to sit over the top of the hidden
select element
$this.after('<div class="styledSelect"></div>');
// Cache the styled div
var $styledSelect = $this.next('div.styledSelect');
// Show the first select option in the styled div
$styledSelect.text($this.children('option').eq(0).text());
// Insert an unordered list after the styled div and also
cache the list
var $list = $('<ul />', {
'class': 'options'
}).insertAfter($styledSelect);
// Insert a list item into the unordered list for each select
option
for (var i = 0; i < numberOfOptions; i++) {
$('<li />', {
text: $this.children('option').eq(i).text(),
rel: $this.children('option').eq(i).val()
}).appendTo($list);
}
// Cache the list items
var $listItems = $list.children('li');
// Show the unordered list when the styled div is clicked
(also hides it if the div is clicked again)
$styledSelect.click(function(e) {
e.stopPropagation();
$('div.styledSelect.active').each(function() {
$(this).removeClass('active').next('ul.options').hide();
});
$(this).toggleClass('active').next('ul.options').toggle(0,
function(){
$('ul.options').jScrollPane();
});
});
// Hides the unordered list when a list item is clicked and
updates the styled div to show the selected list item
// Updates the select element to have the value of the
equivalent option
$listItems.click(function(e) {
e.stopPropagation();
$styledSelect.text($(this).text()).removeClass('active');
$this.val($(this).attr('rel'));
$list.hide();
/* alert($this.val()); Uncomment this for demonstration! */
});
// Hides the unordered list when clicking outside of it
$(document).click(function() {
$styledSelect.removeClass('active');
$list.hide();
});
});
}
}
I recognize this is fairly complicated. At least for me it is... It's the
styling of the drop downs, which is throwing this off (I think). I have
tried to be as thorough as I can here so as to give you a better idea of
what the issue is and the problem I can't seem to conquer. The current
codebase is here:
http://www.summerserver.com/elance/1
Currently there are only school data for the states of IL and NE, so
choosing any other state should bring up the "No Schools Listed For Your
Area" selection.
I can't thank you all enough for helping me with this problem. I have
literally been trying to figure this out for the last 5 days, with no
luck. I've scoured the internet, and I'm truly at a loss... If there is
any information I've left out, please let me know and I'm more than happy
to provide it. Thank you again.

echo '<option value="' . $state_abv .
'">' . $state_abv . '</option>';
}
?>
</select>
</div><!-- //selectStyled -->
This part works fine… and appropriately populates the state field. The
issue is that when the user selects their state, it's not changing the
school select form. The code I'm using for the school select form is as
follows:
<div id="schoolField" class="selectStyled">
<select class="longField styled" name="kp_school1"
id="kp_school1">
<option value="default">CURRENT SCHOOL</option>
</select>
</div><!-- //selectStyled -->
The JS that I'm using to try to get the above schoolField to populate is
as follows:
<script>
var kp_dropdownOpts = {}
$(function(){
<?php
foreach ($state_arr as $sa)
{
if ( isset($stateSchool[$sa]) )
{
foreach ($stateSchool[$sa] as $value)
{
?>
window.kp_dropdownOpts.<?php echo $sa; ?> += '<option
value="<?php echo $value; ?>"</option>';
<?php
}
}
}
?>
$('#kp_state').change(function(){
var state = $(this).val();
var len = 0;
for (var o in window.kp_dropdownOpts[state]) {
len++;
}
if(len > 0){
var newDrop = window.kp_dropdownOpts[state];
$('#kp_school1').html(newDrop.replace('undefined', ''));
}
else {
$('#kp_school1').html('<option value="default">No Schools
Listed For Your Area</option>');
}
});
});
</script>
In addition, I have the following code which styles the drop downs:
// Iterate over each select element
function custom_select()
{
if($('select').length)
{
$('select').not('.s-hidden').each(function() {
// Cache the number of options
var $this = $(this),
numberOfOptions = $(this).children('option').length;
// Hides the select element
$this.addClass('s-hidden');
// Wrap the select element in a div
$this.wrap('<div class="select"></div>');
// Insert a styled div to sit over the top of the hidden
select element
$this.after('<div class="styledSelect"></div>');
// Cache the styled div
var $styledSelect = $this.next('div.styledSelect');
// Show the first select option in the styled div
$styledSelect.text($this.children('option').eq(0).text());
// Insert an unordered list after the styled div and also
cache the list
var $list = $('<ul />', {
'class': 'options'
}).insertAfter($styledSelect);
// Insert a list item into the unordered list for each select
option
for (var i = 0; i < numberOfOptions; i++) {
$('<li />', {
text: $this.children('option').eq(i).text(),
rel: $this.children('option').eq(i).val()
}).appendTo($list);
}
// Cache the list items
var $listItems = $list.children('li');
// Show the unordered list when the styled div is clicked
(also hides it if the div is clicked again)
$styledSelect.click(function(e) {
e.stopPropagation();
$('div.styledSelect.active').each(function() {
$(this).removeClass('active').next('ul.options').hide();
});
$(this).toggleClass('active').next('ul.options').toggle(0,
function(){
$('ul.options').jScrollPane();
});
});
// Hides the unordered list when a list item is clicked and
updates the styled div to show the selected list item
// Updates the select element to have the value of the
equivalent option
$listItems.click(function(e) {
e.stopPropagation();
$styledSelect.text($(this).text()).removeClass('active');
$this.val($(this).attr('rel'));
$list.hide();
/* alert($this.val()); Uncomment this for demonstration! */
});
// Hides the unordered list when clicking outside of it
$(document).click(function() {
$styledSelect.removeClass('active');
$list.hide();
});
});
}
}
I recognize this is fairly complicated. At least for me it is... It's the
styling of the drop downs, which is throwing this off (I think). I have
tried to be as thorough as I can here so as to give you a better idea of
what the issue is and the problem I can't seem to conquer. The current
codebase is here:
http://www.summerserver.com/elance/1
Currently there are only school data for the states of IL and NE, so
choosing any other state should bring up the "No Schools Listed For Your
Area" selection.
I can't thank you all enough for helping me with this problem. I have
literally been trying to figure this out for the last 5 days, with no
luck. I've scoured the internet, and I'm truly at a loss... If there is
any information I've left out, please let me know and I'm more than happy
to provide it. Thank you again.
