SQLCE Issue: update requires the command clone to have a connection object
I am working on a new solution for an existing project. now I am facing
some troubles with the sql ce connection. I modified my connection with
the following class:
namespace CommonTools
{
/// <summary>
///
/// </summary>
public class SQLCEConnectorClass
{
private SqlCeConnection m_openConnection;
/// <summary>
/// Opens the SQLCE connection.
/// </summary>
/// <param name="connectionString">The connection string.</param>
/// <returns></returns>
public SqlCeConnection OpenSQLCEConnection(string connectionString)
{
bool isWorking = false;
while (!isWorking)
{
if (TryToConnect(connectionString))
{
isWorking = true;
}
else
{
// sleep for 100 ms to try the connection again
Thread.Sleep(100);
}
}
return m_openConnection;
}
/// <summary>
/// Tries to connect.
/// </summary>
/// <param name="connectionString">The connection string.</param>
/// <returns></returns>
private bool TryToConnect(string connectionString)
{
try
{
m_openConnection = new SqlCeConnection(connectionString);
if (m_openConnection.State == ConnectionState.Closed)
{
m_openConnection.Open();
return true;
}
}
catch
{
return false;
}
return false;
}
/// <summary>
/// Releases unmanaged and - optionally - managed resources.
/// </summary>
public void Dispose()
{
m_openConnection.Close();
m_openConnection.Dispose();
m_openConnection = null;
}
}
}
so it's possible to use the SQL CE with multiple user, otherwise it is
used by another process and I can not access from a different machine. I
changed also the following code segements:
ConnectionString = "DataSource='" + dbPath + fileName + "';
Password ='" + password + "';";
cn = sqlce.OpenSQLCEConnection(ConnectionString);
// only if the connection string is not empty and a connection to the
database was possible
if (ConnectionString != string.Empty)
{
// for the categories
string sql = "select * from Kategorien";
SqlCeCommand cmd = new SqlCeCommand(sql, cn);
var reader = cmd.ExecuteReader();
while (reader.Read())
{
categories.Add(Convert.ToString(reader[0]));
categoriesSAP.Add(Convert.ToString(reader[0]),
Convert.ToString(reader[1]));
}
}
else
{
XtraMessageBox.Show("Es konnte keine Verbindung zur Datenbank
hergestellt werden!", "Fehler", MessageBoxButtons.OK,
MessageBoxIcon.Error);
return;
}
sqlce.Dispose();
now I want to update my changes:
private void SaveTable()
{
try
{
DataRow[] rows = editedRows.ToArray();
dAdapter.SelectCommand.Connection =
sqlce.OpenSQLCEConnection(ConnectionString);
dAdapter.Update(rows);
int rowCount = dAdapter.Update(dTable);
}
catch (Exception ex)
{
XtraMessageBox.Show(ex.Message, "Fehler",
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
sqlce.Dispose();
}
the first change (SaveTable) will work, without any exception. the second
change does't work. I got the following exception at
dAdapter.Update(rows):
Update requires the command clone to have a connection object. The
Connection property of the command clone has not been initialized.
before I changed it to the new connection class, everything worked as
expected. any suggestions what I made wrong?
thanks, tro

Twitter4j Stream not Closing?
Twitter4j Stream not Closing?
I have been searching all over the internet for a way to stop the stream
of tweets from Twitter's Streaming API. I saw this bit of code, but
nothing happens when it is exicuted, and i still get tweets. I have also
tried to set the connection to null, which gave me an error:
Stream.shutdown();
How can i stop this stream? Thanks.
Here is some more of my code:
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true).setOAuthConsumerKey("xxxxxxxx").setOAuthConsumerSecret("xxxxxx").setOAuthAccessToken("xxxxxx").setOAuthAccessTokenSecret("xxxxxx");
TwitterStream twitterStream = new
TwitterStreamFactory(cb.build()).getInstance();
After this, i check a boolean to see wheather i should close the stream or
note. If flase, then i do. (sort of swapped around, but false = close
here). Here is that it is eclosed in:
if(!CheckTweets)
{
Stream.shutdown();
}
else
{
// Show Tweets....
}

Adding multiple partial views and first one is missing form
Adding multiple partial views and first one is missing form
I have the following:
_ImageGalleryPartial
@if (Model != null)
{
foreach (var item in Model)
{
@Html.Partial("_ImageItem", item);
}
}
_ImageItemPartial
@model WebsiteEngine.Models.PortfolioImage
@{
string url = VirtualPathUtility.ToAbsolute(String.Format("~/{0}",
Html.DisplayFor(m => m.FileName)));
}
@using (Html.BeginForm("DeleteImage", "Portfolio", FormMethod.Post, new {
@class = "deleteImageForm" }))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true);
@Html.HiddenFor(m => m.Name)
@Html.HiddenFor(m => m.FileName)
@Html.HiddenFor(m => m.Order)
@Html.HiddenFor(m => m.PortfolioID)
@Html.HiddenFor(m => m.PortfolioImageID)
<div class="span3">
<div class="item">
<a class="fancybox-button" data-rel="fancybox-button"
title="Photo" href="@url">
<div class="zoom">
<img src="@url" alt="Photo" />
<div class="zoom-icon"></div>
</div>
</a>
<div class="details">
<a href="#" class="icon deleteImage" data-form=""><i
class="icon-remove"></i></a>
</div>
</div>
</div>
}
When I inspect the page elements using Chrome dev tools, the first element
is missing the surrounding form. If I inspect the page source (using
right) click then the form is there. This lead me to believe some JS was
removing the form so I disabled JS but it was still missing.
If change _ImageGalleryPartial so it's like this (notice the addition of
an empty model):
@if (Model != null)
{
@Html.Partial("_ImageItem", new WebsiteEngine.Models.PortfolioImage());
foreach (var item in Model)
{
@Html.Partial("_ImageItem", item);
}
}
Then all the "correct" elements get a form but again, this first item
doesn't.
I'm still inclined to think this is a JS issue but I'm a little stumped as
disabling JS doesn't fix it. Is this some off behaviour with MVC?
Just to note, I have simplified my layout above, I do actually have one or
2 nested forms but assume that's Ok as everything else is Ok, it's just
this first partial that's broken.
Any ideas?

How to complexity
How to complexity
Please can any one provide with a better algorithm then trying all the
combinations for this problem.
Given an array A of N numbers,
find the number of distinct pairs (i, j) such that j >=i and A[i] = A[j].
First line of the input contains number of test cases T.
Each test case has two lines, first line is the number N,
followed by a line consisting of N integers which are the elements of
array A.
For each test case print the number of distinct pairs.
Constraints
1 <= T <= 10
1 <= N <= 10^6
-10^6 <= A[i] <= 10^6 for 0 <= i < N
I think that first sorting the array then finding frequency of every
distinct integer and then adding nC2 of all the frequencies plus adding
the length of the string at last. But unfortunately it gives wrong ans for
some cases which are not known help. here is the implementation.
code:
#include <iostream>
#include<cstdio>
#include<algorithm>
using namespace std;
long fun(long a) //to find the aC2 for given a
{
if(a==1) return 0;
return (a*(a-1))/2;
}
int main()
{long t,i,j,n,tmp=0;
long long count;
long ar[1000000];
cin>>t;
while(t--)

{

A bit of integration involving a continuous function
A bit of integration involving a continuous function
If $f$ is continuous on $[0,1]$ and if $\int_{0}^{1}f(x)x^ndx=0$ for
$n=0,1,2,3...$then $\int_{0}^{1}f^2(x)dx=0$.
This is how I proceeded. For $n=1$, $\int_{0}^{1}f(x)xdx=0$ . (Using by
parts) $\implies$ $x\int f(x)dx]_0^1-\int_{0}^{1}(\int f(x)dx)dx=0$. Let
$I(x)=\int f(x)dx$. Then $I(1)=\int_{0}^{1}I(x)dx$. For $n=2$ we have
$\int_{0}^{1}f(x)x^2dx= x\int xf(x)dx]_0^1-\int_{0}^{1}(\int xf(x)dx)dx=0$
In general for any $n$, $\int_{0}^{1}f(x)x^ndx=x\int
x^{n-1}f(x)dx]_0^1-\int_{0}^{1}(\int x^{n-1}f(x)dx)dx=0$.
Then I don't see how I can use this information to get the desired result.

Function instance variables inside a class
Function instance variables inside a class
I'm trying to implement a so-called static variable in my method, similar
to the decorator method described in this Stackoverflow thread.
Specifically, I define a decorator function as follows:
def static_var(varName, value):
def decorate(function):
setattr(function,varName,value)
return function
return decorate
As the example shows, this can be used to attach a variable to the function:
@static_var('seed', 0)
def counter():
counter.seed +=1
return counter.seed
This method will return the number of times it has been called.
The issue i am having is that this does not work if I define the method
inside a class:
class Circle(object):
@static_var('seed',0)
def counter(self):
counter.seed +=1
return counter.seed
If I instantiate a Circle and run counter,
>>>> myCircle = Circle()
>>>> myCircle.counter()
I get the following error: NameError: global name 'counter' is not defined.
My response to this was that maybe I need to use self.counter, i.e.
class Circle(object):
@static_var('seed',0)
def counter(self):
self.counter.seed +=1
return self.counter.seed
However this produces the error, AttributeError: 'instancemethod' object
has no attribute 'seed'.

How safety is Ubuntu Tweak Janitor for system?
How safety is Ubuntu Tweak Janitor for system?
I had some trouble with Tweak Janitor.
I cleaned my system with all checkboxes that was available.
After cleaning when I restarted PC I caught to text terminal it's all, smt:
Ubuntu 12.04.3 LTS nazar-desctop tty1
nazar-dezsctop login: // I typed correct login + password
nazar-dezsctop password:
and after log in next info:
7 packages can be updated
7 updatees are security updates
I got out from this trouble by next steps:
Stop LightDM with sudo stop lightdm
Install GDM with sudo apt-get install gdm
Start GDM with sudo start gdm
Run sudo dpkg-reconfigure lightdm to set the default display manager for gdm
Restart computer and login.
I wondering to know about safety usage of Ubuntu Tweak Janitor.
Question:
For example what happen if I'll try to use it again in the future?
If I had use LightDM what would happen?
Why ubuntu didn't tall me about these updates after cleaning?

.htaccess help needed
My main domain is red dot com it comes up with ssl as https www dot red
dot com I need to add multiple domains to the subfolders. For instance red
dot co dot uk would point to folder /var/www/html/uk or red dot tv would
point to folder /var/www/html/tv and so on.
My dns servers are pointing right, and I added virtual servers for each
domain but nothing worked so far because the .htaccess is not configured
properly, can someone give me an idea how to configure the virtual server
and .htaccess?
I also wanted to mention that I have 2 seperate ip addresses both pointing
to main domain

Git has --force flag in a lot of operations but when I use them I feel a
bit strange. Like ignoring warning messages in my code.
For example I just wanted to unstage a file and did this:
git rm --cached myfile.ext
git complained error:
the following file has staged content different from both the file and the
HEAD
I really don't care about this error and it seems not to be an issue - I
just want to leave my code as it is, but unstage the file. --force flag
simply solved this issue.
My question is about best practices as I was unable to find any
information about this issue - should one use force flags in git commands
or is it a bad practice?

double border around a container
double border around a container
I wanted to create an effect like this around my border, basically a
double sided border. Currently I am using an image as a background-image,
but the issue comes when I want to make the site responsive. So I want to
re-create this using CSS. Is this even possible?

fade a page in with jquery after a button is clicked
fade a page in with jquery after a button is clicked
with this jquery i can fade the page in after it loads:
<script type="text/javascript">
$(function() {
$('body').hide().fadeIn(1000);
});
</script>
now what i want to do is have it that function happen after a button is
clicked. for example, when the user goes to the page, there would be a
window with a clickable button. after the button was clicked then it would
do that fade in jquery loading the page with a fade in. i was thinking
that it would be some kind of form, but the problem is it needs to hide
the body when the page is loaded, and then fade in to the body after the
button is clicked.

Can std::async call std::function objects?
Can std::async call std::function objects?
Is it possible to call function objects created with std::bind using
std::async. The following code fails to compile:
#include <iostream>
#include <future>
#include <functional>
using namespace std;
class Adder {
public:
int add(int x, int y) {
return x + y;
}
};
int main(int argc, const char * argv[])
{
Adder a;
function<int(int, int)> sumFunc = bind(&Adder::add, &a, 1, 2);
auto future = async(launch::async, sumFunc); // ERROR HERE
cout << future.get();
return 0;
}
The error is:
No matching function for call to 'async': Candidate template ignored:
substitution failure [with Fp = std::_1::function &, Args = <>]: no type
named 'type' in 'std::_1::__invoke_of, >
Is it just not possible to use async with std::function objects or am I
doing something wrong?

Prevent website from resizing
Prevent website from resizing
On the website I'm currently fixing there are two divs displayed Inline.
On resizing the browser window, the div on the right automatically aligns
to fit under the first div instead of staying inline. My question is on
how to prevent this resize and to keep it standard on all screen sizes.
To display this issue, I've attached two screenshots.
Another issue: The screen is vertically scrollable which should not be the
case as the height of html, body or any of the div are not more than 100%
My CSS for the two main divs is as follows:
#menu{
position:absolute;
width:15%;
height:600px;
float:left;
margin-top: 10px;
margin-left: 40px;
}
#content{
position: absolute;
height:600px;
width:73%;
float:left;
margin-top: 10px;
margin-left: 290px;
}
The CSS for the inner 4 divs are as follows
.gallery-image-rest{
background: url('../images/thumbs/rest.jpg');
position: relative;
height:600px;
width:24%;
float: left;
margin-left: 15px;
/*display: inline-block;*/
text-align: center;
}
.gallery-image-replenish{
background: url('../images/thumbs/Replenish.jpg');
position: relative;
height:600px;
width:24%;
float: left;
margin-left:3px;
/*display: inline-block;*/
text-align: center;
}
.gallery-image-rejuvenate{
background: url('../images/thumbs/Rejuvenate.jpg');
position: relative;
height:600px;
width:24%;
float: left;
margin-left:3px;
/*display: inline-block;*/
text-align: center;
}
.gallery-image-reunite{
background: url('../images/thumbs/reunite.jpg');
position: relative;
height:600px;
width:24%;
float:left;
margin-left:3px;
/*display: inline-block;*/
text-align: center;
}
The code has a lot of redundancies but that is second priority as the
client needs the display to be correct before anything else.
Thanks guys.

threads to show progress in java
threads to show progress in java
Here's the situation: My code downloads a file from the internet, also
displays its size and filename.
The problem is that when I'm downloading that file, nothing appears in
that JTextArea and the frame is like "frozen" until the download is
complete.
I even tried to put a progress bar using swingworker class (i asked some
days ago requesting information and I didn't understand how to "integrate"
the swingworker methods you gave me before in my code. I was told that
using Matisse is not recommendable at all in that sort of cases. So I'm
not able to use swingworker.
I've been researching, and I think that the suitable way for me is using a
thread. With, or without a progress bar. Just looking for simple code, I'm
a beginner, thanks

C# how to deal with sessions left open
C# how to deal with sessions left open
I have a ConcurrentDictionary on server side holding on to all the
<SessionId, UserSessions> pairs.
When a new connection is established a cookie is assigned to a client
browser, perm or temp depending on the RememberMe option.
When clients call the LogOut function it removes the session from the
dictionary.
However, when the client browser is simply closed or crashed, and cookie
was per session or expired or deleted, the server side session object in
memory is remained in dictionary and becomes a ghost. Over time these
ghosts will stack up.
My question is, how to improve the design so that the dead sessions can be
cleaned up after they are expired?
I thought about making a timer service running a cleaning schedule, but it
feels not elegent. Is there a simpler way to do this without depending on
an external service?
My setup is .NET 4.5 and IIS8

Trouble runing a c++ project on Windows (Was coded on Linux)
Ok guys, I've been using Ubuntu for a while, so I've been coding all my
projects using NetBeans on ubuntu. Now, due to external causes I need to
code on Visual Studio/Windows. I know migrating projects from one OS to
another may be problematic so I made a new c++ project on Visual and
included all the .cpp files from my project. I'm having the next issues
when I run it, this is the output:

I know it may be caused by some library, these are the libraries I'm using

The program reads a .txt and generates a list of objects. I'll been trying
to figure it out but haven't been able to fix it! Thanks for your time!

Vague kernel exception on D3D11DeviceContext Update Subresource
Vague kernel exception on D3D11DeviceContext Update Subresource
I am developing a class for displaying 10-bit video streams using D3D11.
The solution I went for was to render each frame as a texture to a quad.
As such I have a function for updating the frame/texture from a YUV
surface:
void tenBitDisplay::SetTextureData(short int *yuvData) {
unsigned int size = m_width * m_height, chromaSize;
short int y1, y2, y3, y4, u, v, r, g, b;
DWORD *data;
chromaSize = size * 0.25;
data = new DWORD[size];
for(unsigned int k = 0, j = 0; k < size; k += 2, j++) {
y1 = yuvData[k];
y2 = yuvData[k + 1];
y3 = yuvData[k + m_width];
y4 = yuvData[k + m_width + 1];
u = yuvData[size + j];
v = yuvData[size + chromaSize + j];
convertYUV(y1, u, v, &r, &g, &b);
packRGB(data, r, g, b, k);
convertYUV(y2, u, v, &r, &g, &b);
packRGB(data, r, g, b, k + 1);
convertYUV(y3, u, v, &r, &g, &b);
packRGB(data, r, g, b, k + m_width);
convertYUV(y4, u, v, &r, &g, &b);
packRGB(data, r, g, b, k + m_width + 1);
if (k!=0 && (k+2) % m_width == 0)
k += m_width;
}
if (m_pTexture2D != NULL) {
m_pImmediateContext->UpdateSubresource(m_pTexture2D, 0, NULL,
data, m_width * 4, 0);
}
free(data);
}
Everything executes fine up until it reaches the
m_pImmediateContext->UpdateSubresource(m_pTexture2D, 0, NULL, data,
m_width * 4, 0); call. At some point during execution of this method, the
following exception is thrown:
First-chance exception at 0x751EC41F (KernelBase.dll) in app.exe:
0x0000087D (parameters: 0x00000000, 0x0273D328, 0x0273C760).
If there is a handler for this exception, the program may be safely
continued.
I am guessing this is a problem with the heap, stack or something else to
do with memory. I just can't figure out what precisely, and I have never
encountered such an issue and don't really have much knowledge about where
to start with debugging it. I have checked the preceding loop to make sure
there is no overrun on the buffer and everything is fine.

}
Everything executes fine up until it reaches the
m_pImmediateContext->UpdateSubresource(m_pTexture2D, 0, NULL, data,
m_width * 4, 0); call. At some point during execution of this method, the
following exception is thrown:
First-chance exception at 0x751EC41F (KernelBase.dll) in app.exe:
0x0000087D (parameters: 0x00000000, 0x0273D328, 0x0273C760).
If there is a handler for this exception, the program may be safely
continued.
I am guessing this is a problem with the heap, stack or something else to
do with memory. I just can't figure out what precisely, and I have never
encountered such an issue and don't really have much knowledge about where
to start with debugging it. I have checked the preceding loop to make sure
there is no overrun on the buffer and everything is fine.

Applying outer layer that wrapping two select statement
Applying outer layer that wrapping two select statement
I have two query which has successfully inner join
select t1.countResult, t2.sumResult from (
select
count(column) as countResult
from tableA join tableB
on tableA.id = tableB.id
group by name
)t1 inner join (
select
sum(column) as sumResult
from tableA
join tableB
on tableA.id = tableB.id
group by name
)t2
on t1.name= t2.name
The above query will return me the name and the corresponding number of
count and the sum. I need to do a comparison between the count and sum. If
the count doesnt match the sum, it will return 0, else 1. And so my idea
was implementing another outer layer to wrap them up and use CASE WHEN.
However, I've failed to apply an outer layer just to wrap them up? This is
what I've tried:
select * from(
select t1.countResult, t2.sumResult from (
select
count(column) as countResult
from tableA join tableB
on tableA.id = tableB.id
group by name
)t1 inner join (

How to get parameter in new google map street view url
How to get parameter in new google map street view url
The old street view I can obtain the parameter of ll= for lat and lng,
cbp= for getting heading and pitch from the Share URL such as below
https://maps.google.com/maps?q=London+Borough+of+Hillingdon,+United+Kingdom&hl=en&ll=51.544098,-0.474593&spn=0.0014,0.003484&sll=52.209371,0.117255&sspn=0.005516,0.013937&oq=london&hq=London+Borough+of+Hillingdon,+United+Kingdom&t=m&z=19&layer=c&cbll=51.544098,-0.474593&panoid=p3rE-jwzNFukt6tfwRCm8Q&cbp=12,244.19,,0,0.97
But the new streetview url changes to shorter and different way.

Both of this link open same street view with same camera view.
So is there any method I can get the ll= and cbp from new url?

Testing multiple scenarios under one Unit Test
Testing multiple scenarios under one Unit Test
This is how I am doing my unit test in groovy.
public void testSomeMethod() {
doSomething(1,2,3,4); //this is first test
doSomething(11,22,33,44); //this is second test
}
private void doSomething(a, b, c, d) {
assertEquals(a, actual)
}
Basically I am calling doSomething 2 times with different values under
same test. It might not be a good way to test But I just want to try it
out.
So, the problem is, if the first test fails second does't get executed.
Is there a way I can force it to print fail message and move on to next one?

Is there a way to add a Javascript-based Signature Pad to a Google Form to capture a responder's signature?
Is there a way to add a Javascript-based Signature Pad to a Google Form to
capture a responder's signature?
Is there a way to add in Thomas Bradley's Signature Pad plugin so that
someone who is filling out the Google Form would be able to sign the form?
Would it be possible to use the HTML Service option to create a custom
HTML form web app that can then still upload the responses into a Google
Spreadsheet?
The project I've been asked to look into involves an individual being able
to fill out a form but they would also like to be able to capture a
signature (essentially a web form replacing paper forms) and they would
like to do it all with Google since it is their preferred service. They
also prefer to use Google Spreadsheets.
I'm very new to Google App Scripts and have a beginner's understanding of
Javascript so I may very well misunderstand the uses and potential of
Google App Scripts. Any help or advice is much appreciated.

Sending/uploading xml file in POST method of RestAPI using Ruby
Sending/uploading xml file in POST method of RestAPI using Ruby
I have used HTTPClient for authentication of Rest API and then used file
upload method for uploading file
Code:
require 'HTTPClient'
clnt = HTTPClient.new(path)
clnt.set_auth(path, 'username', 'password')
File.open('E:\Project_Groundwork\RestAPI\RestAPI Docs\postHost.xml') do
|file|
body = [{ 'Content-Type' => 'application/xml; charset=UTF-8',
:content => '<hosts><host hostName="host100"

{ 'Content-Type' => 'application/xml',
'Content-Transfer-Encoding' => 'binary',
:content => file }]
io = clnt.post(path, body)
Above code authenticates successfully but after that returns '415
Unsupported Media type' error message. This error is returned when xml has
incorrect format. Though when I am sending xml data using 'RestClient'
Firefox Addon, then everything works fine.It means that my xml is correct.
Can anyone tell what am I doing wrong here.

not that familiar with a copy constructor, however. This is what I have
uptil now. Can someone please help me with this?

Right definition of HashMap for static variables
Right definition of HashMap for static variables
I have trouble with logical definition of the HashMap.
For example I create the following class to store some mandatory data, I
just wanna know that is it good implementation or not? I used static
HashMap because I need these HashMaps all over the time since my
application is alive.
public abstract class DataTable {
private static HashMap<String, String[]> mainData = new
HashMap<String, String[]>();
public static void putData(String[] data) {
// put some data
}
public static String[] getData(String alias) {
// return entered data with the given alias
}
}
Any suggestion would be appreciated...

My mysql table carshes and I can't find the reason
My mysql table carshes and I can't find the reason
I have an online game site, and I get this error on my site:
Warning: mysql_query(): Unable to save result set in
/home/fravianx/public_html/tx25/GameEngine/Database/db_MYSQL.php on line
2750
and here is the part of code that makes the error :
function getTrainingList() { $q = "SELECT * FROM " . TB_PREFIX . "training
where vref != '' AND eachtime<=(1000*(".time()."-commence))"; $result =
mysql_query($q, $this->connection); return
$this->mysql_fetch_all($result); }
the code itself looks fine (well, at least to me) but somehow it makes the
"training" table in mysql database to crash (doesn't do what it supposed
to be doing, which is creating troops on players accounts)
I have tried everything I could find online but still couldn't fix this :(
can you help me with this?

Sqrt function errors incorporating
Sqrt function errors incorporating
How would I incorporate the equation into my program? Basically adding a
new column of info when it compiles:
relative_error_per_cent = 100 *((my_sqrt_1(n) – sqrt(n)) / sqrt(n)
I know that it is suppose to go inside the for loop but what else is
missing? Im getting errors. Been trying at this for a while
#include <iostream>
#include <math.h>
using namespace std;
double my_sqrt_1(double n)
{
double x = 1;
for(int i = 1; i < 10; ++i)
x = (x+n/x)/2;
return x;
}
int main()
{
for(auto k : { -100,-10,-1,0,1,10,100})
{
double relative_error_per_cent = 100*((my_sqrt_1(n) – sqrt(n)) / sqrt(n))

Android - YouTube AdSense does not render on an Android WebView
Android - YouTube AdSense does not render on an Android WebView
I have a WebView in Android, and most things render fine. My Youtube
videos render fine, but the ads on them do not show up. I checked and
JavaScript is enabled. So I am not sure why the ads do not render.
Here is the code that I use:
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
webview = new WebView(this);
setContentView(webview);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(1);
webview.getSettings().setPluginState(PluginState.ON);
WebSettings webSettings = webview.getSettings();
webSettings.setLoadsImagesAutomatically(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setUseWideViewPort(true);
webview.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
webview.setWebChromeClient(new WebChromeClient(){});
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setAppCacheEnabled(true);
webSettings.setAppCachePath(getApplicationContext().getFilesDir().getAbsolutePath()
+ "/cache");
webSettings.setDatabaseEnabled(true);
webSettings.setDatabasePath(getApplicationContext().getFilesDir().getAbsolutePath()
+ "/databases");
webview.loadUrl("http://javatester.org/javascript.html");
}
Would anyone know why the AdSense ads do not render, and how I can make it
render?
Thanks!

android external storage encryption keys
android external storage encryption keys
Any one knows where android is keeping private keys for external storage
encryption? There is such option (ext storage enc) in some versions of
android 4.1+ (at least in samsung series).
The thing is that it warns you before encryption that if your phone breaks
you wont be able to recover data. I assume it is because as always
encryption keys are encrypted with user password. So user password alone
is useless and the keys are kept somewhere in tge internal memory.

Is it hardcoding to type out values in a formula?
Is it hardcoding to type out values in a formula?
I am working on a class assignment and one of the things covered in this
weeks text is hardcoding and how it is frowned upon.
My question is if I physically put in a value that is part of the formula,
is that considered hardcoding?
example: the volume of a sphere is (4/3) * PI * r^3 should I declare (4/3)
as variable in the beginning of my block code? or should I take it a step
further and declare the whole formula?
I hope what I am asking makes sense to everyone, and for a little extra
information here is the my code:

How to use Messagepack with JSON?
How to use Messagepack with JSON?
I am planning to use Messagepack in our project. Currently, we are using
JSON in our project and we are writing serialize JSON document into
Cassandra. Now we are thinking to use Messagepack which is an efficient
binary serialization format.
And I believe using MessagePack in our project is almost a drop-in
optimization. Below is my code which is serializing the JSON document
using ObjectMapper.
public static void main(String[] args) throws IOException {
final long lmd = System.currentTimeMillis();
Map<String, Object> props = new HashMap<String, Object>();
props.put("site-id", 0);
props.put("price-score", 0.5);
props.put("confidence-score", 0.2);
Map<String, Category> categories = new HashMap<String, Category>();
categories.put("123", new Category("0.4", "0.2"));
categories.put("321", new Category("0.2", "0.5"));
props.put("categories", categories);
AttributeValue av = new AttributeValue(); // using Jackson in this class
av.setProperties(props);
Attribute attr = new Attribute(); // using jackson in this class
attr.instantiateNewListValue();
attr.getListValue().add(av);
attr.setLastModifiedDate(lmd);
System.out.println(attr);
// serialize it
try {
String jsonStr = new ObjectMapper().writeValueAsString(attr);
// write into database
System.out.println(jsonStr);
} catch (JsonGenerationException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Both of my classes, AttributeValue and Attribute are using Jackson
annotations and making a JSON document for me.
Now I am not sure, how to use Messagepack in my above code as I am not
able to find clear documentation on it. Can anyone help me with that?

this is my output.php file:
<?php

<?php myText(); ?>

and last but not least, this is my outputFunction.php file:
<?php
include('variables.php');
function myText(){
echo "Your salary per month is: " . $_POST['salary'];
}
?>
Now you're thinking "why have he split up his code in different files?"
Well first of all, I split the variables from functions.php because I
wanted outputFunctions.php to get the variables from variables.php so i
could echo my `$_POST['salary']; . The function myText(); outputs the text
just fine, but it doesnt output the $_POST['salary'];.
I do not know why it doesnt work, I just wonder if you could be my extra
eyes and see if I've done some mistake.
PS! Don't down vote my question just because you think it's stupid. I am
having problem with this issue and been working on it for hours without
advancing anywhere.

Age Verification PHP
Age Verification PHP
I'm using a script that works wonderfully to verify age for a website I'm
working on. Currently it's using a dropdown menu to select the Month, Day,
Year. I was hoping it was possible to change the dropdown to have the user
input the Month, Day, Year instead.
Here is the code:
<?php
define('MIN_AGE', 21); // Enter the minimum age that your
website visitors must be to view your content (replace 18 with
your number)
define('COOKIE_DAYS', 30); //Enter the number of days you
would like the cookie to last (replace 30 with your number)
// BE CAREFUL EDITING ANYTHING BELOW THIS LINE //
date_default_timezone_set('America/Los_Angeles');
function get_birth_drops($year = '', $month = '', $day = '')
{
$out = '';
$year = $year ? $year : '';
$month = $month ? $month : '';
$day = $day ? $day : '';
$month_select = '<label>MM: <select name="bmonth"
id="bmonth"><option value=""></option>';
for($i = 1; $i <=12; $i ++)
{
$selected = ($i == $month) ? ' selected':'';
$month_select .= '<option value="' . $i . '"' .
$selected . '>' . $i . '</option>';
}
$month_select .= '</select></label>';
$day_select = ' <label>DD: <select name="bday"
id="bday"><option value=""></option>';
for($i = 1; $i <=31; $i ++)
{
$selected = ($i == $day) ? ' selected':'';
$day_select .= '<option value="' . $i . '"' .
$selected . '>' . $i . '</option>';
}
$day_select .= '</select></label>';
$year_select = ' <label>YYYY: <select name="byear"
id="byear"><option value=""></option>';
for($i = 2010; $i >= 1950; $i --)
{
$selected = ($i == $year) ? ' selected':'';
$year_select .= '<option value="' . $i . '"' .
$selected . '>' . $i . '</option>';
}

$out = $month_select . $day_select . $year_select;
return $out;
}
function calculateAge($birthday){

}
?>
Any thoughts? Thanks a ton!

WinJS Promise progress function does not get executed
WinJS Promise progress function does not get executed
I am trying to create a basic promise with a progress function like:
asyncCall().then(function () {
that.output("complete");
},
null,
function(v) {
that.output(v);
}).done();
function asyncCall() {
return new WinJS.Promise(function (complete, error, progress) {
progress("some progress");
setTimeout(function () {
complete();
}, 1000);
});
}
I would expect this to output 'progress' for 1 second and then display
'complete'; however, 'progress' is never outputted. Debugging the
javascript, the progress function gets called on the promise object
however it gets to this code (line 1447 of base.js) and listeners is
undefined:
function progress(promise, value) {
var listeners = promise._listeners;
if (listeners) {
Any idea what I'm missing to handle the progress event?

anti-replay attack for secure cookies?
anti-replay attack for secure cookies?
In the system that i'm working on, we are having some session cookies on
the client side that we need to protect against the replay attack ! So I
find the following paper
http://www.cse.msu.edu/~alexliu/publications/Cookie/cookie.pdf from this
forum
http://security.stackexchange.com/questions/7398/secure-session-cookies. I
really like the way that they put things together. There is only one
problem with this and that is the use of SSL session key (this is used for
anti-replay purpose). I have some problems to get this parameter in my
code (we use .Net framework and the server is running on IIS7.0). So I was
wondering whether anyone has implemented this method for his/her system
and whether you have a suggestion on replacing this parameter with another
one.
BTW, I know that server side sessions are more secure than client side
cookies, but my team currently prefers cookies than sessions.
Thanks

Parsing SEC RSS Title field using regex
Parsing SEC RSS Title field using regex
All, I have an RSS feed from the SEC with company title as follows; e.g.,
10-Q - What ever INC (0000123456) (Filer)
so the general structure is:
form_name + whitespace + dash + whitespace + company_name + " (" +
SIC_Number + ") (Filer)"
I need to extract the company_name and SIC_Number. Note the form_name can
have a dash, and the company name will have white spaces. This can be done
(I'm using python) by using the re.split function for the dashes, and
again for the brackets, but it's ugly.
What would the proper RegEx be?

Git: send commit to another branch so I can merge back, without switching branches
Git: send commit to another branch so I can merge back, without switching
branches
So I have 2 branches, the main one and the one I'm working on a parallel
release.
A --> B --> C (master)
\
-> E --> F (parallel)
The parallel branch will always merge from master. Always. And modify upon
it.
A --> B --> C --> D --> H (master)
\ \ *merge*
-> E --> F --> G --> J (parallel)
This is easy to do if I switch branches. But, if I'm working on parallel,
can I do this without switching branches? The problem with switching is
that it takes a long time to go back and forth (specially with Unity 3D,
because it keeps rebuilding the library)!
So say I'm on F, while master is still on A. Then I wanted to make few
commits on master B and C then merge them into G. How would I do it,
again, without switching branches?

Python's ConfigParser: Cross platform line endings?
Python's ConfigParser: Cross platform line endings?
Does anyone know how Python deals with ConfigParser line endings in the
different OSes? Because it follows the Windows INI format. But what about
Linux?
(As you know, Windows text line endings are typically CRLF, and Unix's are
CR.)
I want users of my app to take their config files (.INI files) easily from
Windows to Linux and I'd like to know if that's going to be problematic.
If it does use different line endings for Unix and Windows, what do you
recommend?

Using CSS properties in CSS selectors?
Using CSS properties in CSS selectors?
Context: I have three spans, A B C D (in that order). Based off of what is
put in a form next to these spans, I turn the visibility off or on of
these spans.
There's a line break in A and C that makes the display something like this :
A
B C
D
But if I hide C this ends up being :
A
B D
because the line break is not displayed.
What I'd like to do is add some other element (C') that would display if B
is displayed and C isn't. So that , if C isn't there, I can still get the
line break:
A
B (C')
D
I'm pretty sure this is possible by using a combination of class-based CSS
switching and the :after pseudo-selector, but I'd rather like to avoid
having to go in and modify the Javascript to change from the current
display:show/none mechanisms. So my question ends up being :
Is it possible to 'inspect' currently set styles (such as 'display') in
CSS rules ? I'd like to be able to do something similar to the attribute
mechanism where I can do :
A[display='show']~B[display='none']:after {
content : '\a';
}
But just looking at the selectors I don't see how I could accomplish this
without declaring new classes.

Android UI without using classic android UI
Android UI without using classic android UI
I'm starting to learn android development and i learned that to make a GUI
you can use the "android classic UI" (button, textfield...etc).
I was wondering how was the angry birds (or any other "nice looking" UI)
UI was done. I guess they didn't used the "classic android UI"
I just want to know what do they use?
I know a lot of you will get mad at me for asking this kind of question.
Sorry but it's a question that i have in mind for a long time now.
Thank you!

SELECT Only Records With Duplicate (Column A || Column B) But Different (Column C) Values
SELECT Only Records With Duplicate (Column A || Column B) But Different
(Column C) Values
I apologize for the confusing title, I can't figure out the proper wording
for this question. Instead, I'll just give you the background info and the
goal:
This is in a table where a person may or may not have multiple rows of
data, and those rows may contain the same value for the activity_id, or
may not. Each row has an auto-incremented ID. The people do not have a
unique identifier attached to their names, so we can only use
first_name/last_name to identify a person.
I need to be able to find the people that have multiple rows in this
table, but only the ones who have multiple rows that contain more than one
different activity_id.
Here's a sample of the data we're looking through:
unique_id | first_name | last_name | activity_id
---------------------------------------------------------------
1 | ted | stevens | 544
2 | ted | stevens | 544
3 | ted | stevens | 545
4 | ted | stevens | 546
5 | rachel | jameson | 633
6 | jennifer | tyler | 644
7 | jennifer | tyler | 655
8 | jennifer | tyler | 655
9 | jack | fillion | 544
10 | mallory | taylor | 633
11 | mallory | taylor | 633
From that small sample, here are the records I would want returned:
unique_id | first_name | last_name | activity_id
---------------------------------------------------------------
dontcare | ted | stevens | 544
dontcare | jennifer | tyler | 655
Note that which value of unique_id gets returned is irrelvant, as long as
it's one of the unique_ids belonging to that person, and as long as only
one record is returned for that person.
Can anyone figure out how to write a query like this? I don't care what
version of SQL you use, I can probably translate it into Oracle if it's
somehow different.

From that small sample, here are the records I would want returned:
unique_id | first_name | last_name | activity_id
---------------------------------------------------------------
dontcare | ted | stevens | 544
dontcare | jennifer | tyler | 655
Note that which value of unique_id gets returned is irrelvant, as long as
it's one of the unique_ids belonging to that person, and as long as only
one record is returned for that person.
Can anyone figure out how to write a query like this? I don't care what
version of SQL you use, I can probably translate it into Oracle if it's
somehow different.
Flex-box: Align last row to grid
Flex-box: Align last row to grid
I have a simple flex-box layout with a container like:
.grid {
display: flex;
flex-flow: row wrap;
justify-content: space-between;
}
Now I want the items in the last row to be aligned with the other.
justify-content: space-between; should be used because the width and
height of the grid can be adjusted.
Currently it looks like
Here, I want the item in the bottom right to be in the "middle column".
What is the simplest way to accomplish that? Here is a small jsfiddle that
shows this behaviour.
