please help me to prove this exercise in modern algebra

please help me to prove this exercise in modern algebra

Suppose $W$ be a free R-module with basis $X=\{x_1,...,x_n\}$ . If $\phi:
W \rightarrow W$ is an R-module endomorphism with matrix $A$ relative to
$X$ , then the determinant of the endomorphism $\phi$ is defined to be the
determinant $|A| \in R$ and is denoted $|\phi |$. How to show $|\phi |$ is
independent of the choice of $X$?
thanks in advanced..

IBM System X M4 Series Servers Oracle Linux Support

IBM System X M4 Series Servers Oracle Linux Support

Is Oracle Linux runnable/compatible with the M4 Series of the IBM System X
Servers?
In their compatibility website, most compatible machines listed are those
from Dell and HP..there are IBM system x..but all are of older models..
(This is the link of the tested configurations/compatible machines for
Oracle Linux:
http://linux.oracle.com/pls/apex/f?p=102:1:2850003747338068:pg_R_27262430945134281:NO&pg_min_row=1&pg_max_rows=20&pg_rows_fetched=20)
We currently have no machines to test the Oracle Linux if it will work...
If you guys could confirm for me if it will work on IBM System x M4 series
that would be great and appreciated :)
This is for one of our clients who would like to run Oracle Linux on one
of their machines that they will purchase from us.

I need the recurrence relation for Fabonacci with Life Span = 2.999
I think it will be
f(n) = 1 where n%2 = 0 & n > 2 and f(n) = 2 where n%2 = 1 $ n > 2

Redirect after persist Symfony2 form and Doctrine

Redirect after persist Symfony2 form and Doctrine

on an web application based on Symfony2 I'm developing a page in which I
can insert a new record on my DB. The Insert operation works properly,
anyway actually after the confirmation the datas are correctly inserted
but the web application return me on the same form that I used to insert
the data. How can I redirect the page to another route, for example to the
page that show me new inserted data?
Here the action in my Controller used to create the new record:
public function newAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(new AnagraficaType(), new
Anagrafiche() );
if ($request->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
$anagrafica = $form->getData();
$em->persist($anagrafica);
$em->flush();
}
}
return $this->render('AcmeMyBundle:Anagrafica:new.html.twig',
array('form' => $form->createView()));
}
Here the part of routing.yml used for the page to create the new record:
AcmeMyBundle_newAnag:
pattern: /anagrafica/new
defaults: { _controller: AcmeMyBundle:Anagrafica:new}
Here the part of routing.yml for the page that permit me to show detailed
a single record of my 'anagrafica' objects in DB:
AcmeMyBundle_showAnag:
pattern: /anagrafica/{id}
defaults: { _controller: AcmeMyBundle:Anagrafica:show }
requirements:
_method: GET
id: \d+
Here the action in my controller that manage the page to show detailed a
single record of my 'anagrafica' objects in DB:
public function showAction($id)
{
$em = $this->getDoctrine()->getEntityManager();
$anagrafica = $em->getRepository('AcmeMyBundle:Anagrafiche')->find($id);
if (!$anagrafica) {
throw $this->createNotFoundException('Unable to find anagrafica
post.');
}
return $this->render('AcmeMyBundle:Anagrafica:show.html.twig', array(
'anagrafica' => $anagrafica,
));
}
This is the view new.html.twig:
{% extends 'AcmeMyBundle::layout.html.twig' %}
{% block title %}{% endblock %}
{% block body %}
{{ form(form) }}
{% endblock %}
This is the Form Type:
<?php
namespace Acme\MyBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class AnagraficaType extends AbstractType
{
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\MyBundle\Entity\Anagrafiche',
'cascade_validation' => true,
));
}
public function buildForm(FormBuilderInterface $builder, array
$options)
{
// Create the form
$builder->add('nome', 'text', array('label' => 'Nome: ',
'required' => false));
$builder->add('cognome', 'text', array('label' => 'Cognome: ',
'required' => false));
$builder->add('data_nascita', 'date', array('label' => 'Data
nascita: ', 'required' => false));
$builder->add('luogo_nascita', 'text', array('label' => 'Luogo
Nascita: ', 'required' => false));
$builder->add('indirizzo', 'text', array('label' =>
'Indirizzo: ', 'required' => false));
$builder->add('telefono', 'text', array('label' => 'Telefono:
', 'required' => false));
$builder->add('email', 'text', array('label' => 'Email: ',
'required' => false));
$builder->add('save', 'submit');
}
public function getName()
{
return 'anagrafica';
}
}
I need to extract the id of the new persisted record, and automatically
redirect to the /anagrafica/$id route (AcmeMyBundle_showAnag) after the
confirmation of the form.
Suggestion? Thanks.

How to embed the latest vine videos automatically?

How to embed the latest vine videos automatically?

How do I embed the latest vine videos automatically? I know you can embed
each video alone but I want to automatically embed it so that it is not so
inconvenient to have to copy and paste the code to my website everytime. I
found a website vinalwidget.com that lets you display the latest vine
video THUMBNAILS, but not videos, using an iframe code generated from that
site. Its kind of neat and convenient but like I said, it is only
thumbnails that links to a video page. If this can be achieved, then is it
possible to do it using videos instead??

wpf textbox errortemplates in a Managed Addin Framework Addin

wpf textbox errortemplates in a Managed Addin Framework Addin

I've created a textbox style to contain a validation.errortemplate for use
in a UserControl class. If the UserControl is loaded in the normal,
non-MAF way, I can see the validation rule kicking in and getting visual
feedback (thick red border, a circular bang to the right of the textbox,
and an error message-in-a-tooltip) -- everything works the way I expect it
to.
However... if I load that same UserControl in as an AddIn, I lose the
visuals. (I do see the error tooltip behaving correctly, so I know my
validation rule is firing; I just don't see the border and bang symbol.
My AddIn, by the way, is based on MSDN's example for an
'addin-which-provides-a-usercontrol.'
I know a few of the limitations of an AddIn (e.g., video won't play in an
AddIn UserControl); is this another limitation, or am I screwing up?
Thanks in advance!

Visual Studio 2012 Update 3 - initializer list & variadic templates

Visual Studio 2012 Update 3 - initializer list & variadic templates

Recently I have installed Visual Studio 2012. After the installation I
updated my IDE with update 3 to guarantee functionality of my programs on
Windows XP.
Everything is working well, but I still can not use initializer list and
variadic templates! Do I need any extra updates to get this working with
Visual Studio 2012?

difference between mult, multu simulating in c

difference between mult, multu simulating in c

I'm writing a c program and decodes mips 32 bit instructions and simulates
their functionality minus the bitwise part. I don't know how I should be
differentiating between signed and unsigned operations here.
For instance, given registers rd and rs, i need to multiply and put the
result in in rd.
for the mult instructions, it's as simple as this:
reg[rd] = reg[rs] * reg[rt];
What should the multu instruction be? Do I need to be doing bitwise
operations on the contents of the registers first?
I also need to do:
-add, addu, -div, divu -sub, subu
Is it the same distinction in functionality for all of them?

ThrowCards in python

ThrowCards in python

Given is an ordered deck of n cards numbered 1 to n with card 1 at the top
and card n at the bottom.
The following operation is performed as long as there are at least two
cards in the deck:
Throw away the top card and move the card that is now on the top of the
deck to the bottom of the deck.
My task is to find the sequence of the last k discarded cards and the last
remaining card.
Each line of input contains two non-negative numbers
n, where n ¡Ü 5000
k, where k < n
For each input line produce two lines of output.
The sequence of k discarded cards
The last remaining card.
See the sample for the expected format.
Sample input
7 2
19 4
10 5
6 3
4000 7
Output for sample input
Last 2 cards discarded: [4, 2]
Remaining card: 6
Last 4 cards discarded: [2, 10, 18, 14]
Remaining card: 6
Last 5 cards discarded: [9, 2, 6, 10, 8]
Remaining card: 4
Last 3 cards discarded: [5, 2, 6]
Remaining card: 4
Last 7 cards discarded: [320, 1344, 2368, 3392, 832, 2880, 1856]
Remaining card: 3904
My code will keep printing out the exact answers but with None on the
following line.
I am so confused why it will print None after each output.
Here is my code:
def throw_card(n,k):
lst=[]
bst=[]
for i in range(1,n+1):
lst.append(i)
while lst[0]!=lst[1] and len(lst)>1 and n<=5000 and k<n:
bst.append(lst.pop(0))
if len(lst)==1:
break
else:
lst.append(lst[0])
lst.remove(lst[0])
print('Last',k,'cards discarded: ',bst[n-(k+1):])
print('Remaining card: ',lst.pop())
print(throw_card(7,2))
print(throw_card(19,4))
print(throw_card(10,5))
print(throw_card(6,3))
print(throw_card(4000,7))
my output:
Last 2 cards discarded: [4, 2]
Remaining card: 6
None
Last 4 cards discarded: [2, 10, 18, 14]
Remaining card: 6
None
Last 5 cards discarded: [9, 2, 6, 10, 8]
Remaining card: 4
None
Last 3 cards discarded: [5, 2, 6]
Remaining card: 4
None
Last 7 cards discarded: [320, 1344, 2368, 3392, 832, 2880, 1856]
Remaining card: 3904
None

Missing one column when using Google chart API

Missing one column when using Google chart API

I did compare my code to the example code from Google and I couldn't find
anything different. I have no idea why my chart only display 2 data
columns instead of 3. Is it because of my browser (I'm using Chrome) ? I
tried with IE and had the same problem.
Google's example code:Example
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>Chart</title>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">google.load('visualization', '1',
{packages: ['corechart']});</script>
<script type="text/javascript">
function drawVisualization2() {
var data = google.visualization.arrayToDataTable([

['27/09/2013', 4.0, 9.0, 4.0],
['29/09/2013', 5.0, 8.0, 4.0]
]);
var options = {title : 'Daily usage of heaters',
vAxis: {title: "Minutes"},
hAxis: {title: "day"},
seriesType: "bars",
series: {2: {type: "line"}} // This is not the root of the problem. If I
change it to 3, the chart can be displayed normally but it will not have
the average line anymore.
};
var chart = new
google.visualization.ComboChart(document.getElementById('chart2_div'));chart.draw(data,
options);}google.setOnLoadCallback(drawVisualization2);
</script>
</head>

Can anyone give me an advise ?
Thank you very much.

Getting Variables Passed In URL Laravel

Getting Variables Passed In URL Laravel

Probably a basic question but I can't seem to get it.
I am wanting to grab the variable in my url to my controller.
// index view
@foreach ($paymentInfos as $p)
<tr>
<td><a href="{{ URL::action('AdminController@getPackingSlip',
array('order_id' => $p->order_id)) }}"> {{ $p->order_id
}}</a></td>
<td>{{ $p->lastname }} {{ $p->firstname }}</td>
<td>{{ $p->buyer_email }}</td>
</tr>
@endforeach
// route
Route::get('printpackingslip', 'AdminController@getPackingSlip');
// Controller
class AdminController extends BaseController {
/**
* Display a listing of the resource.
*
* @return Response
*/
public function getPackingSlip()
{
$rules = array('order_id' => 'order_id');
return View::make('admin.packingslip')->with($rules);
}
}
When you click on the link it goes to
www.domain.com/printpackingslip?order_id=3
I do not know how to grab the order_id=3 in my controller.
Also would I be better off using the :(num) to generate a URI of
/printpackingslip/3 or does it not matter?
For example:
// in my first view have:
<td><a href="{{ URL::to('printpackingslip', array('order_id' =>
$p->order_id)) }}"> {{ $p->order_id }}</a></td>
// then my route:
Route::get('printpackingslip/(:num)', 'AdminController@getPackingSlip');
Thanks!

Java anonymous override doesn't work

Java anonymous override doesn't work

I am currently experiencing a weird issue with anonymous method override
and inherits. It's difficult to explain clearly, so to begin with here is
a representation of my code :
public abstract class A {
public void draw() {
someAction();
}
}
public class B {
// Other methods
}
ArrayList< A > listA = new ArrayList< A >();
B objectB = new B() {
@Override
public void draw() {
someActionOverriden();
}
}
listA.add( objectB );
for( A item : listA ) {
item.draw();
}
The thing is : the draw() method that is override anonymously is never
called. I presume this may be because "item" is of class A, and so it
never goes to the anonymous method, but is there a way to implement this
kind of design?

Multi Dimensional array, display certain values from array index

Using jquery handler in Angular

Using jquery handler in Angular

I have been using Angular for a bit and really find myself much more
efficient and produce many few lines of code than I did in Backbone and
jquery. However, I work with other developers that are primary creating in
Backbon/jquery components/controls we all share. Since these are complex
components/controls that I cannot rewrite in Angular I need to find a way
to use them from within Angular.
In the specific case I am dealing with a control that create a dialog that
lets users created entries in a series of help request systems or log
bugs. This code is working in a number of applications. Here is a simple
example :
<div class="foo">Help</div>
And then the handler.
$(".foo").ShowHelp({project:"myproject", app:"MyApp"});
Note "foo" is used to position the dialog.
In Angular I tried to create add an ng-click directive and in my
controller handle the click, but ShowHelp is not invoked. This is the
angular code:
<div class="foo" ng-click="doShowHelp()">Help</div>
In the controller I have
$scope.doShowHelp = function() {
console.log("in doShowHelp");
$(".foo").ShowHelp({project:"myproject", app:"MyApp"});
};
I see the log message in the console, but nothing seems to happen. Any
ideas on what I am doing wrong.
Thanks in advance

How do I find out the value of these dwFlags constants?

How do I find out the value of these dwFlags constants?

I'm looking at the MSDN documentation for ChangeDisplaySettings. For the
dwFlags option, you can pass in 0 or one of the other listed flags.
However, I can't figure out how to reference those flags directly, nor
figure out what their actual long value is to use in their stead.
I'm making these calls from a C# application using this:
[DllImport("User32.dll")]
public static extern long ChangeDisplaySettings(ref DeviceMode lpDevMode,
int dwflags);
Is there a way I can reference the flags directly, or, barring that, find
out what their actual values are?

ImeAction Search is changed to Done after tapping

ImeAction Search is changed to Done after tapping

I have an Edittext for searching on Listview. I have set imeOption to
'IME_ACTION_SEARCH' so that softkeyboard will show search key on it. The
problem is when I tap on search key on keyboard if edittext contains no
text in it, the search key changes to 'Done' instead of dismissing the
keyboard. If the Edittext contains some text in it the search key works
well.

no space between navbar and items after in the new bootstrap?

no space between navbar and items after in the new bootstrap?

So i'm messing around with the new bootstrap V3, and there is absolutely
one thing that is driving me insane. There is no space btween a fixed top
navbar and the item that follows it. I've tried changing the padding on
the item(whether it be jumbotron or carousel) and the padding on the
navbar to no avail. Its literally driving me insane. any fixes?

Python if statement troubleshooting

Python if statement troubleshooting

Python Version : 2.7
Just wondering what is wrong with the following code :
def bmi_cat(bmi):
if bmi < 18.5:
return "underweight"
elif (bmi >=18.5 or bmi < 25):
return "normal"
elif (bmi >=25 or bmi < 30):
return "overweight"
else:
return "obese"
Basically if i enter 17 it gives me the correct answer, but it gives me
normal for anything above 18.5 (3000 gives normal instead of obese,etc...)

CSS clear:both not working for table cell with a background image?

CSS clear:both not working for table cell with a background image?

I'm developing an email and would like an image to show up only on a
mobile device.... SO I created an empty with a span inside, and styled the
span to have a background image.
The problem is, I'd like the image to take up a whole row, instead of
being right next to the headline. I tried clear:both and display:block but
I'm not sure why it's not working. I also tried setting the width to 100%
but that just throws everything off... any suggestions?
http://jsfiddle.net/pEDSn/
<table id="headline_body_copy_top" width="532" border="0" cellspacing="0"
cellpadding="0">

C# DateTime.ParseExact with backslashes in format

C# DateTime.ParseExact with backslashes in format

I've got some sub directories that are named with dates like so:
C:\SomeDirectory\201309\01
C:\SomeDirectory\201309\02
C:\SomeDirectory\201309\03
C:\SomeDirectory\201309\04
C:\SomeDirectory\201309\05
etc.
What I'm trying to do is get the directory listing and then use Linq to
limit my results based on a date range.
I've got it working like so:
string path = @"C:\SomeDirectory";
DateTime f = new DateTime(2013, 9, 1);
DateTime t = new DateTime(2013, 9, 3);
DateTime dt;
var dirs =
Directory.GetDirectories(path, "*.*", SearchOption.AllDirectories)
.Where(d => DateTime.TryParseExact(
d.Substring(Math.Max(0, d.Length - 9)).Replace("\\", null),
"yyyyMMdd",
CultureInfo.Invarient,
DateTimeStyles.None,
out dt)
&& f <= dt
&& dt <= t);
I would, however, like to change the TryParseExact portion so that I don't
have to replace the backslash - like so:
DateTime.TryParseExact(
d.Substring(Math.Max(0, d.Length - 9)),
@"yyyyMM\dd",
CultureInfo.Invarient,
DateTimeStyles.None,
out dt)
But, it seems TryParseExact does not like that format. I was thinking this
may have something to do with the CultureInfo - but I was unable to track
down a possible solution to help me with the backslash.
Any assistance would be greatly appreciated!

C# TCPClient - Data Mismatch

C# TCPClient - Data Mismatch

I need some help. I have a simple server-client application using C#
TCPClient
The problem that I am having is that when a client sends a message to
server, the server returns a 4 bytes response containing an number.
But, every 3 or 4 responses the bytes are in the same wrong place.
For example:
server response with a byte array containing an integer 243:
byte[0] => 243 byte[1] => 0 byte[2] => 0 byte[3] => 0
The client receives the 4 bytes as follows:
byte[0] => 0 byte[1] => 0 byte[2] => 243 byte[3] => 0
This is an integer number of 15925248 not 243.
Here's the snippet of server code. the code executes when client sends a
message:
byte[4] resp = new byte[4]; Buffer.BlockCopy(BitConverter.GetBytes(243),
0, resp, 0, 4); clientStream.Write(resp, 0, resp.Length);
clientStream.Flush();
Here's the snippet of client code to receive:
Byte[] rec = new Byte[4] {0xx0, 0x00, 0x00, 0x00}; if (netStream.CanRead)
{ int numberOfBytesRead = 0; do { numberOfBytesRead = netStream.Read(rec,
0, rec.Length); } while (netStream.DataAvailable); }
I have done the following: - verified that the server indeed is sending
the byte array correctly.
I don't know what am I doing wrong here. Or is there a bug in my code or not.
Please help me.

Find duplicate lists where element order is insignificant but repeat list elements are significant

Find duplicate lists where element order is insignificant but repeat list
elements are significant

I've got an odd problem where I need to find duplicate collections of
items where the order doesn't matter but the presence of duplicate values
within a collection does matter. For example, say I have the following
list of lists:
lol = [
['red'],
['blue', 'orange'],
['orange', 'red'],
['red', 'orange'],
['red', 'red'],
['blue', 'orange', 'red'],
['red', 'orange', 'blue']
]
In my case, the unique collection would be:
unique_lol = [
['red'],
['blue', 'orange'],
['orange', 'red'],
['red', 'red'],
['blue', 'orange', 'red']
]
And the information I'm looking to obtain are the duplicate lists:
dup_lol = [
['orange', 'red'],
['blue', 'orange', 'red']
]
I don't care which duplicate is reported as the duplicate, i.e. ['orange',
'red'] vs ['red', 'orange'], just that the duplicate combination is
reported. I first tried to use a set of frozensets:
sofs = {frozenset(x) for x in lol}
However, this approach gets tripped up by the ['red', 'red'] list, which
gets converted to ['red']:
set([frozenset(['red']),
frozenset(['orange', 'red']),
frozenset(['blue', 'orange', 'red']),
frozenset(['blue', 'orange'])])
Plus, this doesn't give me the duplicates, just the unique ones, and I
cannot run difference against the list of lists anyway.
I'm sure I can iterate over the parent lists brute force style, but I feel
like I'm missing something simple. I almost need a dictionary where the
key is the ordered list, and the value is the number of times that
combination appears, but that lists cannot be dictionary keys and that
just sounds odd anyway.

Code-Test-Code cycle in Amazong Cloud (AWS)

Code-Test-Code cycle in Amazong Cloud (AWS)

I new to Amazon AWS and want to create a cloud-based REST API in Node.js.
Usually I develop the program along with testing it. It means I write some
tests, and then write the code that makes those tests run successfully. So
in a typical programming session, I may run the tests or the app tens of
times.
When I do this locally it is easy and quick. But what if I want to do the
whole process on Amazon cloud? How does this code-test-code cycle look
like? Should I upload my code to AWS every time I make a change? And then
run it against some server address?
I read somewhere in the documentation that when I run a task for a few
minutes (for example 15min), Amazon rounds it up to 1hour. So if in a
typical development session I run my program 100 times in an hour, do I
end up paying for 100 hours? If yes, then what will be the solution to
avoid these huge costs?

C++ CreateProcess - System Error #2 can't find file - what is wrong with my file path?

C++ CreateProcess - System Error #2 can't find file - what is wrong with
my file path?

I am trying to open a pdf via firefox with CreateProcess(), I am a
beginner and know nothing about using CreateProcess, but in my last
question someone pointed out the MSDN on it... it shows that:
To run a batch file, you must start the command interpreter;
set lpApplicationName to cmd.exe and set lpCommandLine to the
following arguments: /c plus the name of the batch file.
Therefore I created a batch file that runs perfectly fine with the
system() command, there are no problems with the batch file.
I can't figure out why the system can't find the file and I don't know if
its the batch file, the exe in the batch file, the pdf doc in the batch
file or the location of cmd.exe... Any help is greatly appreciated...
void openPDF(char scansQueue[][MAX_NAME], int index)

Trying to understand foreign key syntax

Trying to understand foreign key syntax

Just starting out with SQL. I understand the idea of foreign keys just
fine, but I'm trying to learn the syntax of how to implement them and
reading the sqlite page just gives me more questions than answers. Is
there any difference in the following two lines?
CREATE TABLE child(x REFERENCES parent(id));
CREATE TABLE child(FOREIGN KEY x REFERENCES parent(id));
Also, from my understanding, columns are specified by the "table.column"
format, so I'd want to type "parent.id" above, but it seems all the
reading I've done says "parent(id)". What's the difference between the two
and why use parent.id sometimes and parent(id) others?
Are we not supposed to bind any kind of affinity (I think I'm using the
terminology correctly) to the foreign keys because it should just use
whatever the parent key uses?
I have more questions, but this is a good start. Thanks in advance for any
help!

Android screen capture delay due to writing data in the file

Android screen capture delay due to writing data in the file

I have a rooted device and i successfully capture the screenshot of

os.writeBytes("/system/bin/screencap -p " + path + "; \n");`
but in the command i provide the path where i want to save the file and
system take time to write the image in the file. so I want to know can we
directly take the image data from process in the form of bytes because I
want to send the current image to the server immediately.

Dynamic Array in C

Dynamic Array in C

Array by definition is a chunk of contagious memory locations. What i
understand from Dynamic is that we can allocate memory at run time. So for
Dynamic Array lets say we allocate 100 memory spaces at run time. Now we
perform some other operation and allocate few memory spaces for other
variables. Since the array we created was meant to be Dynamic so i suppose
we can add more elements t it occupying more memory spaces. But what i
fail to understand is how this is going to be contagious because the next
memory addresses are per-occupied and Arrays by definition are supposed to
be Contagious???

Blink upon incoming call android

I am developing an android app, where I want make the home screen blink
upon incoming call. I tried calling the below startblinking() method
within a activity and the screen blinks fine.
But, when I try to call the same method within the Ring state of a

the service class doesnt have a window.
The method getWindow() is undefined for the type PhoneListener
..
private void startblinking()

timerforblinking.scheduleAtFixedRate(new TimerTask()
{
@Override

getWindow().setAttributes(layoutParams);
timerforblinking.purge();
timerforblinking.cancel();
}
}
});
}
}, 0, 500);
Is there a possible workaround to achieve the screen blinking upon
incoming calls.
Please help.Thanks!

Extract content of Zip file after reading Zip file from Exchange server through JavaMail

Extract content of Zip file after reading Zip file from Exchange server
through JavaMail

Here is the program which reads the content of a ZIP file.
http://www.java2s.com/Code/Java/File-Input-Output/ReadingtheContentsofaZIPFile.htm
But my problem here is this line : ZipFile zf = new
ZipFile("C:/ReadZip.zip");
In above ZipFile constructor it is passing path of the ZIP file.
In my case I don't have that ZIP file stored anywhere. In my case I am
first reading that ZIP file from the exchange email account through
JavaMail API and then I need to read the content of that ZIP file.
Through JavaMail I am able to connect to exchange and read the email and
extract the attachment and then see if that attachment is a zip file - all
that is working - now I have the zip file - how I dynamically pass to
ZipFile constructor ZipFile zf = new ZipFile("C:/ReadZip.zip");
Really appreciate your help in this. I need to get this done over the
weekend.
Thank you.

Returning a response in Flask

Returning a response in Flask

I have a code like this
def find_user(user_id):
if not users.lookup(user_id):
return jsonify(success=False, reason="not found")
else:
return users.lookup(user_id)
@app.route(...)
def view1(...):
user = find_user(...)
if user:
do_something
return jsonify(success=True, ....)
The point is I have a helper function and if condition is met I want to
return the response right away. In this case if user is not found, I want
to return a request stating the request failed and give a reason.
The problem is because the function can also return some other values (say
a user object) .
Ideally this is the longer code
def view(...)
user = users.lookup(user_id)
if not user:
return jsonify(success=False....)
# if user is true, do something else
The whole point of the helper function find_user is to extract out common
code and then reuse in a few other similar apis.
Is there a way to return the response directly? It seems like this is a

NoClassDefFoundError, jar is present

NoClassDefFoundError, jar is present

I am attempting to use the com.integralblue.HttpResponseCache
compatibility library with my Android application. I have copied its jar
file together with its dependency, com.jakewharton.disklrucache, into the
"libs" folder of my project.
When running the program, any call on HttpResponseCache causes the program
to fail with a NoClassDefFoundError on com.jakewharton.disklrucache. Both
JARs are present in the libs folder and can be imported. Google search
turns up absolutely nothing.
How do I solve a NoClassDefFoundError when all required JARs are present?

JavaScript How to make an image to change color onmouseover?

JavaScript How to make an image to change color onmouseover?

I have a button and an image and want them to change color onmouseover.
The button changes color fine:
<script>
function secondColor(x) {
x.style.color="#000000";
}
function firstColor(x) {
x.style.color="#ffaacc";
}
</script>
<input onmouseover="secondColor(this)" onmouseout="firstColor(this)"
type="submit"><br>
How can I do the same thing with the image? Is there any way:
<img src="..." ......
Or do I have to have a second image to replace the first one onmouseover
and this is the only way?

Decipher - Excessive wake lock

Decipher - Excessive wake lock

I am getting message in log as below and then app is dying:
Excessive wake lock in domain.mobile.app.MusicPlayer pid zzz held xxxx
during yyyy
My application is a music player. I didn't obtain any wake lock in initial
version and player kept playing for hours without any stop. Then I decide
to make things clever and added the wake lock. So far so good, player
didn't change playing pattern if I play big music fragment for example CD
image with duration of 74 minutes. However if I split the images on tracks
and release and obtain lock for every separate track, I am getting a
message as in subject approximately after 30 minutes playiback and my
application gets ejected. As work around I can simply return to my
original idea to do not use the lock. However I obtained a curiosity why
it behaves in this way and what numbers in error message mean, perhaps it
will give me some clue. more details : I am obtaining PARTIAL_WAKE_LOCK
once and then play with acquire and release during track changing.
Interesting that some gentleman was complaining about stopping app doing
network communication here Application running in background getting
closed due to Excessive Wake lock error I have a solution for him, since
in my cases phone can keep connection in active state for hours, but
unfortunately I am black out from answering questions.
Attention experts moderators of the system, I highly respect your
experience and unbelievable brain power but be even smarter and do not try
to point me to some other questions and tell it is duplicate, ok?

I want to delete a worksheet when I delete a row in another worksheet (EXCEL 2007)

I want to delete a worksheet when I delete a row in another worksheet
(EXCEL 2007)

In my workbook, I have a worksheet that contains a list of form-names,
with each form-name in a separate row. For each of these rows, there is a
separate worksheet with that form-name containing information about that
form.
I would like to include this functionality:
When the user deletes a row from the first worksheet, the corresponding
worksheet is also deleted.
My initial approach tried using the Worksheet_Change event to trigger code
to capture the form-name from the row deleted, and then to delete the
worksheet with that name, but I cannot capture that data since the row is
already deleted.
Is this functionality possible? Thanks.

How to run Unit Tests in Angular with dependency on a global

How to run Unit Tests in Angular with dependency on a global

I'm trying to use a i18n module called lingua in a new angular project
(based on ng-boiletplate). You can find this module and a short
instruction on github
I think it's a great approach bringing gettext style i18n to angular. The
integration as mentioned on the github readme did work flawlessly.
But with the integration as it is, based on a manual bootstrap of angular
I'm not able to run my tests.
angular.element(document).ready(function() {
Lingua.init(document, function() {
angular.bootstrap(document, ['modulename']);
});
});
My project is at the moment based on the angular phonecat tutorial. Ang
when running the tests I get this error because of the global i18n which
should be declared in the "Lingua.init" method before the bootstrap of
angular.
ReferenceError: i18n is not defined in /path/to/lingua/lingua.js (line 54)
Is there a possibility to run that custom bootstrap before the tests get
executed? Or is there a way to mock the global?
I'm pretty new to angular, but i realy like the gettext style compared to
other i18n modules for angular out there.
I'm in hope someone can give me a hint, because this problem is annoying
me for days now ;-(

Perl Old Number of Element in Hash Assignment Error

Perl Old Number of Element in Hash Assignment Error

I was learning Perl Objects. I wrote a simple constructor in a module file
my_module.pm:
#!/usr/bin/perl -w
#
package my_module;
use strict;
use warnings;
use diagnostics;
sub new {
my $class = shift;
my %params = @_;
my $self=bless{

_para2=>$params{'mypara2'}
},$class;
return $self;
}

and I am creating an object in a main file main.pl:
#!/usr/bin/perl -w
use strict;
use warnings;
use diagnostics;
use lib::my_module;
sub _start(){
print "Main Function Started\n";
create_schedules::new(
'mypara1' => 'This is mypara1',

);
}
_start();
As soon as I run main.pl, I got following error:
Main Function Started

(W misc) You specified an odd number of elements to initialize a hash,
which is odd, because hashes come in key/value pairs.

Unique device identification

Unique device identification

We are developing in-house web-based application for viewing data reports
while targeting on smartphones and tablets. Our customer asked us for
possibility that only certain devices could access the content. Hence we
use technologies based on javascript/HTML5 we are no capable of reading
unique ID like IMEI or device uuid. The idea is to be able to automaticly
create time-independent fingreprint of device with abovementioned
technologies.
The question is are we able to create unique device fingerprint with
javascript/HTML5?
The clue might be information available or known by browser (e.g.
http://browserspy.dk/)

jQuery ajax returning unexpected data type

jQuery ajax returning unexpected data type

attempting to implement some server side error checking for input in the
very useful "handsontable" jscript library.
the following call works great:
jQuery.ajax({
url: "index.php?option=com_catalogscontroller=batchsave",
data: {"formData": querydata.getData().splice( 0, 1 ) },
dataType: 'JSON',
type: 'POST',
success: function ( response ) {
if( response.success ) {
} else {
querydata.loadData( response.data );
}
}
});
I thought the most effective way to do error checking is on the server
(PHP) side, to create a multidimensional array to track any errors
discovered by the server and then return that array with the form data in
the same ajax call. So I modified the server code to return both the form
data and the error array back to the javascript ajax call. i.e.:
if( !empty( $errors ) ) // $errors is an multi dimensional array same size
as the form data
$result['success'] = false;
$result['msg'] = 'There were errors detected';
$result['data']['form'] = $formData;
$result['data']['errors'] = $errors;
}
echo json_encode( $result );
and then on the client side, the javascript routine above has been
modified to:
jQuery.ajax({
url: "index.php?option=com_catalogscontroller=batchsave",
data: {"formData": querydata.getData().splice( 0, 1 ) },
dataType: 'JSON',
type: 'POST',
success: function ( response ) {
if( response.success ) {
} else {
formErrors = response.data.errors; // formErrors is a global
querydata.loadData( response.data.form );
}
}
});
The original function of the form is preserved (the form data is retrieved
and properly inserted in the html), but formErrors returns with a result
to me that is baffling. An alert immediately after the assignment 'alert(
formErrors )' shows something like a list:
true,true,false,true,true
and I can also alert on a specific index without problem e.g. alert(
formErrors[0][2] ); would display 'false'. But outside of the ajax call,
the array seems to be inaccessible, giving 'undefined' errors. And both in
the ajax call, and in routines outside of the ajax call alert( typeof
formErrors ) displays 'object' and alert( formErrors) gives the same comma
list as above, but I don't want an object, I am expecting an array OR i'd
be happy with an object as long as i could access it by indices. What am I
missing here?

I understand that somehow these 2 scripts need to be combine but I really
do not know how.
