Android - after loading URL with webview can i change background color
I have a webview and im loading an external HTML form a site. I try to
change the background color using javascript function:
function changeBGC(color){
document.bgColor = color;
}
and that does not work. but if i load locally then im able to change the
background color. Is there some kind of security inhibiting me from
changing a web page i load into the webview externally ?

How do I use wildcards with php and mysql prepared statements?
How do I use wildcards with php and mysql prepared statements?
I have followed examples from other people on here who also had the same
problem but I can't get it to work. I just changed my code to use prepared
statements for safety and before the change I would get results from the
query using a certain string for $prof and now that same string won't
return any results. the query is empty every time. I don't receive any
errors.
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
$tempProf = $_POST["professor"];
$tempProfArray = explode("=",$tempProf);
$prof = $tempProfArray[1];
$postString = '';
$con=mysqli_connect("localhost","root",".......","......");
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
if(empty($prof)) {echo "notFound";}
else
{
$stmt = $con->prepare("SELECT * FROM professors WHERE name LIKE ?");
$prof = '%' . $prof . '%';
$stmt->bind_param('i', $prof);
$stmt->execute();
$profTemp = $stmt->get_result();
while ($profResult = $profTemp->fetch_assoc())

Open map location from Apple maps in my mapping app
Open map location from Apple maps in my mapping app
I'm developing an iOS mapping app. I would like to open a location from
the built-in maps app into my app. Ideally, my app would show up in the
Maps location sharing sheet along with Mail, Twitter, and Facebook. Is
this possible?
The best I've come up with is configuring my app as a routing app so that
Maps can send a routing request to my app, and using the destination as
the point being shared. There are a few problems with that, though. First,
my app doesn't do routing, so that's misleading to the user. Second, in my
opinion, there are too many steps for the user to get to the routing
options screen. Lastly, Apple might not approve an app that advertises
itself to the system as being a routing provider but doesn't actually do
any routing.
I've searched around quite a bit, but I haven't seen this question asked,
and I haven't found anything in Apple's documentation. Any suggestions?

Angularjs: Set form to dirty on model change [Advanced]
Angularjs: Set form to dirty on model change [Advanced]
I'm having a peculiar case on my hands. I'm using the number-polyfill for
input[type="number"] in my Angular app. Now, the problem with that is that
it's doesn't take into accound Angularjs's way of handling things.
Like, if I increment/decrement the input value programatically, the
ngModel associated with the input does not get the updated value.
I've resolved that by writing a custom directive, and passing the model
into the pollyfill
angular.module('appModule').
directive('type', ['$parse', '$timeout', function($parse, $timeout) {
restrict: 'A',
require: '?ngModel',
link: function($scope, iElement, iAttrs, ngModel) {
...
if iAttrs.type is 'number'
iElement.inputNumber(ngModel) // <-- THIS LINE
...
}
}
In the polyfill code, I've modified this:
increment = function(elem) {
...
if (model != null) {
model.$setViewValue(newVal);
}
...
}
which works perfectly. Now, the problem is that even after updating the
model's value, the associated form does not become dirty. In my code, it's
not possible to pass the form as an argument into this polyfill.
I tried using model.$dirty = true, but that's not working.
Any other way?

MVC Ajax Post Requirements
MVC Ajax Post Requirements
Does the ActionResult Method in the Controller require the attribute
[HttpPost] to successfully respond to an ajax post from JQuery?
$.ajax({
url: "~/../../User/AssignPermission",
type: "POST",
data: $.postify({ "p_permId": optionSelectedPerm.value, "p_UserId":
iUserId }),
cache: false,
success: function () {

},

}
});
Controller::
[HttpPost]
public ActionResult AssignPermission(int p_permId, int p_Userid)
{
blah blah blah dance with the provided Id's
persist new permission for user to Disk
return RedirectToAction("UserPermissions", "User", new {
uzrEditId = p_Userid });
}
I was successful getting back into the controller with a GET ( including
the data values as parameters) but this isnt allowing me to update the
View so I want to try a redirect but this will need a POST. Of course it
was a different ActionResult in the controller which danced with View
Model lists.. That should be pointless since UserPermissions", "User" does
that all in the beginning
function SwapPermission(optionSelectedPerm) {
$.ajax({
url: '~/../../User/AssignPermission',
data: $.postify({ "p_permId": optionSelectedPerm.value
}),

datatype: "json",

In our Oracle(11g)-based application, we are making heavy use of pipelined
functions. Now it turns out that error reporting from such functions is
difficult, as shown in the (cut-down) example below. The procedure exists
to be called from Java, and it shall receive errors occurring anywhere
during the PL/SQL execution.

I am using list in sencha touch 2.2.1. And I have to add css only on

But it add that 'gigaspace' class to whole list and not to active item.

Inverted Axis Panning Direction with 2 Range Axes in JFreeChart?
Inverted Axis Panning Direction with 2 Range Axes in JFreeChart?
I have a chart with 2 range axes. I have the datasets mapped properly to
the two axes, but when I pan the chart, they move in opposite directions
(one goes up, one goes down)? Is there a way to invert the pan direction
while maintain the order of the axis labels? I want negative values on top
of both axes, and positive on the bottom; I just need the movements
synced.
It's not obvious to me if the pan direction is setable in any way
(although I could see this being desirable).
I asked this on the official JFreechart Forum, but haven't had any luck
with replies yet.

TreeSet and compareTo() method. Single sort or multiple sorts
TreeSet and compareTo() method. Single sort or multiple sorts
Im currently working on a program, where im using a TreeSet to store
unique keys. I'm using a TreeSet, because I want them sorted.
As of now, I have been making a TreeSet object, and added the strings
one-at-a-time, when needed.
TreeSet set = new TreeSet();
set.add("How");
set.add("Are");
set.add("You");
Supposedly, the TreeSet uses the compareTo method in the Compareable
interface, to sort the strings. That would mean that the TreeSet would
have to do a sort each time I add a String to it.
Now my question is this: Would it be more efficient to create a HashSet
and then create the TreeSet after all strings are added to the HashSet?
TreeSet<String> treeSet = new TreeSet<String>(set);
My thoughts are going about whether the TreeSet would only need to do a
single sort that way.
Thanks in advance

Remove unvanted clicks in generated sound in AS3
Remove unvanted clicks in generated sound in AS3
I am having the following problem when generating sound wave in Flash.
This is the generator part :
const SAMPLING_RATE:int = 44100;
const TWO_PI:Number = 2 * Math.PI;
const TWO_PI_OVER_SR:Number = TWO_PI / SAMPLING_RATE;
const SAMPLE_SIZE:int = 8192 / 4;
function generateSine(fq:Number):ByteArray
{
var bytes:ByteArray = new ByteArray();
var sample:Number;
var amp:Number = 1;
for (var i:int=0; i<SAMPLE_SIZE; i++)
{
sample = amp* Math.sin(i * TWO_PI_OVER_SR * fq );
bytes.writeFloat(sample);
}
bytes.position = 0;
return bytes;
}
and this is the playback part:
function playbackSampleHandler(event:SampleDataEvent):void
{
var sample:Number;
for (var i:int = 0; i < SAMPLE_SIZE && soundData.bytesAvailable; i++)
{
sample = soundData.readFloat();
event.data.writeFloat(sample);
event.data.writeFloat(sample);
}
}
function onClickPlay(e:MouseEvent)
{
soundData= new ByteArray();
soundData.writeBytes(generateSine(440),0,generateSine(440).length);
soundData.position = 0;
morphedSound.addEventListener(SampleDataEvent.SAMPLE_DATA,
playbackSampleHandler);
soundChannel = morphedSound.play();
}
Quick explanation: I basically write values for the sine function into the
ByteArray and than playback handler reads that array and plays back the
sound. I write only one 8192/4 sample buffer.
Problem: My problem is that when you do this there are annoying clicks on
the end of sound, which are the artifacts of sine wave being cut on a
value other than 0. So my question is how can I avoid this?
Bonus: I would also like to know how can I generate for example exactly
100 ms of sine wave when buffers in Flash are so strict i.e. from 2048 to
8192 ?
Links: If it helps my code is based on this tutorial
http://www.bit-101.com/blog/?p=2669 and my own explorations.

Python list slicing efficiency
Python list slicing efficiency
In the following code:
def listSum(alist):
"""Get sum of numbers in a list recursively."""
sum = 0
if len(alist) == 1:
return alist[0]
else:
return alist[0] + listSum(alist[1:])
return sum
is a new list created every time when I do listSum(alist[1:])?
If yes, is this the recommended way or can I do something more efficient?
(Not for the specific function -this serves as an example-, but rather

The problem is I want the value of position_x (2170) and position_y

seems I'm not able to put
<xsl:value-of select="Root/Sensor/position_x" />
into the transform.
Is there a way to achieve this or am I going about this the wrong way?
EDIT:
If I try to have the line:
<g transform="translate(<xsl:value-of select="position_x"/>,<xsl:value-of
select="position_y" />)" id="S">
I get the error: '<', hexadecimal value 0x3C, is illegal in XML attribute

How to make the client perform a http post with php?
How to make the client perform a http post with php?
I'm building some efficiency tools for a crappy website. This website uses
http-posts for some of it's navigation. What I need is that when a user
runs a script on an url (redirect.php), I want the client to post to an
url on an external site, with some variables.
I know I could do this with javascript, creating a form and posting to it,
but I would prefer doing it with php if possible. It needs to be the
client that get's forwarded, because they are authenticated with the
website that I'm sending them to.

There is an urn which contains 3 marbles (2 black and 1 white). The person
who gets to pick the white marble gets to win $1000 whereas the individual
who picks the black marble walks away with nothing. The marbles that are
taken out are not replaced. Assuming that there are only 2 individuals,
how to show, using LIE that it does not matter whether you are the first
or second to pick the marble? Thanks

Retrieving count of a core data relation
Retrieving count of a core data relation
I searched high and low but I couldn't find exactly what I was looking
for. My question is similar to this, but slightly different:
Core Data - Count of Related Records
Let's say I have a Car entity which has a one to many relation with a
Person entity. This means that the car could have multiple people driving
it, but each person drives only one car.
I want to be able to execute only one predicate wherein I could achieve
the following:
All cars which are 'red'.
Return only the 'Year' and 'Color' attributes of the matching car.
Return a count of how many people are driving this car (i.e the size of
the NSSet of People inside each resulting Car).
Is it possible to do all this with one query?
I know how to do this with multiple queries. I would just use
setPropertiesToFetch and use a filtered predicate to achieve 1 and 2
above. I would then perform another count query (countForFetchRequest) on
the Persons entity for every car to find how many Person(s) drive each
car.
The key is the 3rd requirement above. I want to do everything in one
predicate and I don't want to bring all of the Person entity objects into
memory (performance) on the initial query. Furthermore it hurts to call
another countForFetchRequest query for each car.
What's the best way to do this?
Thanks!

zend server ce: Reset username
zend server ce: Reset username
I installed zend server on Ubuntu 12.04. I went to localhost:10082 to view
the console. I set a user name and password and then I was logged into the
console. The next day I tried logging in, but I must have forgotten the
user name.
How can I reset the user name?
I tried:
(1) Uninstall with apt-get purge `dpkg -l | grep zend | awk '{print $2}'`
(2) Reinstall, but the console does not ask me to set a user name and
password.
I also tried resetting my password because I thought the username was correct
(1) /usr/local/zend/bin/php /usr/local/zend/bin/gui_passwd.php <your new
password>
But still no luck.
How Can I remove everything and restart all over so I can reset the user
name?

do_shortcode doesnt extract WORKING shortcode
I've got strange problem. I'm making page via Ajax and I need Form plugin
there. It uses shortcodes and it work well in default templates (twenty
thirteen), but it's not installed.

[wp_caption] => img_caption_shortcode
[caption] => img_caption_shortcode
[gallery] => gallery_shortcode
[audio] => wp_audio_shortcode
[video] => wp_video_shortcode )
it's list of installed shortcodes and [Form] isnt there, but it works via
the_post(); My Ajax script looks like this:
echo "<div id=\"aside\">";
$post = get_page_by_title('right');
$code = "Form";
echo extracted_shortcode();
echo $post->post_content;
echo "</div>";
function extracted_shortcode() looks like this:
global $post, $code;
$pattern = get_shortcode_regex();
preg_match("/".$pattern."/s", $post->post_content, $matches);
if (is_array($matches) && $matches[2] == $code) {
$shortcode = $matches[0];

Can someone tell me where is problem? I'm doing this second day and
shortcode from gallery plugin at one of mine sites works well since 2
months.

Closing keyboard after button click (breaks if no EditText is focused on)
Closing keyboard after button click (breaks if no EditText is focused on)
I put this on my button listener:
InputMethodManager inputManager
=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),InputMethodManager.HIDE_NOT_ALWAYS);
It works perfectly for when the keyboard is up: it closes the keyboard and
then continues its execution. The problem is that when no EditText was
ever pressed (none of them are highlighted/focused on), it breaks and the
app "stops working".
I guess it would be nice if I could check if an EditText had ever been
pressed.

Windows Communication Foundation Callbacks
Windows Communication Foundation Callbacks
I have a WCF callback server.The server invokes callbacks on registered
clients every 2 seconds. After few hours, the communication channel on the
client gets aborted and the client stops receiving callbacks. No exception
is thrown on the server side. If I restart the client without restarting
the server; all is well and the client starts to receive callbacks again.
I am not sure what is causing the callback channel on the client side to
abort. Note that no exception is thrown on the server side. Simply
restarting the client solves the problem and the client starts receiving
callbacks again, I am not sure as to why the callback channel on the
client side is getting aborted in the first place after a few hours. Any
suggestions will be most helpful. Thanks.

php Frontend Scala/Play backend SOA - who has done it?
I am thinking of a large scale application that uses php in frontend and
scala in backend - communicating over rest. php would run on nginx. I feel
more comfortable with php (and javascript) in the frontend because it is
easier to find frontend-devs for this stack.
Do people have real life experiences with that setup?

Are there any edditional parameters to be set?

Another nonlinear ODE of second order.
Another nonlinear ODE of second order.
I have problems finding out whether this initial value problem has an
explicit form solution or if it is possible to grind out a term-by-term
representation of this solution using power series expansions.
\begin{equation}f^{\prime\prime}(x)-\frac{f(x)-a}{b}f^{\prime}(x)^2=0,\quad
x\in(0,1),\qquad f(1/2)=a,\,f^{\prime}(1/2)=\sqrt{2\pi b}.\end{equation}
where $a\in\mathbb{R}$ and $b>0$ are constants.
I have tried the following: Find a solution for the easier problem,
\begin{equation}f^{\prime\prime}(x)-\frac{f(x)-a}{b}f^{\prime}(x)=0,\quad
x\in(0,1),\qquad f(1/2)=a,\,f^{\prime}(1/2)=\sqrt{2\pi b}.\end{equation}
where $a\in\mathbb{R}$ and $b>0$ are constants. Now, solve the original
system with the $f^{\prime}(x)^2$ replacing the easier $f^{\prime}(x)$.
However, I can't make sense of substituting the squared term into my
calculations...
Any help or hint is greatly appreciated.

Printing out a binary tree with increased leading white spaces per level
Printing out a binary tree with increased leading white spaces per level
Lets say I have the tree a binary tree
0
1 2
3 4 5 6
7 8
At the moment I am printing them out traversing my tree in java (recursively)
private static void preorderTraverseTree(BinaryTree<Integer> tree,
Position<Integer> root) {
if (root != null) {
if (tree.hasLeft(root)) {
if(External(tree, tree.left(root))){
printQ(tree.left(root), true);
}
//if it not an external node, External(tree, Pos<Integer>)
else if(!External(tree, tree.left(root))){
//System.out.println(counter(3) + )
printR(tree.left(root), true);
//System.out.println("external");
}
preorderTraverseTree(tree, tree.left(root));
}
}
}
This is one part of the recursive the other part is the same but just for
the right roots rather than the left.
My printQ and R are as follow
private static void printQ(Position<Integer> result, boolean yes) {
if (yes) {
System.out.println("Y->Q" + result.element() + ":");
} else {
System.out.println("N->Q" + result.element() + ":");
}
}
private static void printR(Position<Integer> result, boolean yes) {
if (yes) {
System.out.println("Y->R" + result.element());
} else {
System.out.println("N->R" + result.element());
}
}
This just prints out the element at the node of which has been given in
and a statement true or false for Y and N to appear.
This prints out the following
Q0:
Y->Q1:
Y->Q3:
Y->R7
N->R8
N->R4
N->Q2:
Y->R5
N->R6 (R denotes an external node)
However my question is how can I get it to have leading white spaces to
denote the children for each node? Like so,
Q0:
Y->Q1:
Y->Q3:
Y->R7
N->R8
N->R4
N->Q3:
Y->R2
N->R8
Basically 3 white spaces per level, so 0 for the first, 6 for the second 9
for third and so on. Apart from Q0 which is the root of the tree, I wanted
this to have no white spaces.
EDIT: The children from the original ROOT are 1 and 2, so these should
have the same amount of whitespace before them
Things I have tried so far
Firstly I implemented a counter that counted 3 extra white spaces per
recursion, however I soon found that to be silly since it just printed
them all like a staircase.
I tried setting a boolean flag and making it add white space beforehand
dependent on whether the flag was true or false. Had no luck there
either...
Does anyone have an idea of how I could go about adding this in?
Cheers in advance,
Jim
PS: Post for any clarifications below
Lets say I have the tree a binary tree
0
1 2
3 4 5 6
7 8
At the moment I am printing them out traversing my tree in java (recursively)
private static void preorderTraverseTree(BinaryTree<Integer> tree,
Position<Integer> root) {
if (root != null) {
if (tree.hasLeft(root)) {
if(External(tree, tree.left(root))){
printQ(tree.left(root), true);
}
//if it not an external node, External(tree, Pos<Integer>)
else if(!External(tree, tree.left(root))){
//System.out.println(counter(3) + )
printR(tree.left(root), true);
//System.out.println("external");
}
preorderTraverseTree(tree, tree.left(root));
}
}
}
This is one part of the recursive the other part is the same but just for
the right roots rather than the left.
My printQ and R are as follow
private static void printQ(Position<Integer> result, boolean yes) {
if (yes) {
System.out.println("Y->Q" + result.element() + ":");
} else {
System.out.println("N->Q" + result.element() + ":");
}
}
private static void printR(Position<Integer> result, boolean yes) {
if (yes) {
System.out.println("Y->R" + result.element());
} else {
System.out.println("N->R" + result.element());
}
}
This just prints out the element at the node of which has been given in
and a statement true or false for Y and N to appear.
This prints out the following
Q0:
Y->Q1:
Y->Q3:
Y->R7
N->R8
N->R4
N->Q2:
Y->R5
N->R6 (R denotes an external node)
However my question is how can I get it to have leading white spaces to
denote the children for each node? Like so,
Q0:
Y->Q1:
Y->Q3:
Y->R7
N->R8
N->R4
N->Q3:
Y->R2
N->R8

Regarding simple inheritance in C#
Regarding simple inheritance in C#
I have a question regarding simple inheritance in C#.
Here is the code:
class Mammal
{
int age { get; set; }
public Mammal(int age)
{
this.age = age;
}
}
class Dog : Mammal
{
string breed { get; set; }
public Dog(int age, string breed)
: base(age)
{
this.breed = breed;
}
}
class Program
{
static void Main(string[] args)
{
Dog joe = new Dog(8, "Labrador");
Console.WriteLine("Joe is {0} years old dog of breed {1}", joe.age,
joe.breed); // gives error
}
}
This gives error since it cannot access the age and breed parameters. So I
make age and breed public in Mammal and Dog class respectively. This makes
the program to run fine.
But my question is shouldn't ideally the parameters be made private or
non-public and only accessed through public methods? If that's the case,
then how can I access the non-public parameters in Program class?
Thanks

Only getting Length of string for converting list to datatable
Only getting Length of string for converting list to datatable
I'm writing a program in C# VS 2012 WinForms and found this block of code
on StackOverflow to transfer a list to a datatable.
public static DataTable ToDataTable(List<String> data)
{
PropertyDescriptorCollection properties =
TypeDescriptor.GetProperties(typeof(String));
DataTable table = new DataTable();
foreach (PropertyDescriptor prop in properties)
table.Columns.Add(prop.Name,
Nullable.GetUnderlyingType(prop.PropertyType) ??
prop.PropertyType);
foreach (string item in data)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
table.Rows.Add(row);
}
return table;
}
I was wondering if there was a way to return the actual string itself and
not just the length of the string. If anyone can point me in the right
direction that would be much appreciated. Thanks.

Is it a good idea SEO-wize to nest sections inside articles?
Is it a good idea SEO-wize to nest sections inside articles?
I'm wondering which is the best way to go about grouping inside my site
pages.
I'm using wordpress, by default it puts every page contents inside an tag.
In my "Services" page, I have different ones. I'm wondering whether it
would be a good idea to group them in section tags so the structure would
be:
<article>
<h1>services</h1>
<section>service 1</section>
<section>service 2</section>
<section>service 2</section>
</article>
Would this be good for SEO, or should I use a different structure?

OpenWrt: LuCI: how to implement limited user access
OpenWrt: LuCI: how to implement limited user access
Goal: two users root and user. Root can access everything via
web-interface, but user should see only some parts of the menus.
One option would be to pass "sysauth" option to every module in question.
That is not very practical, because the user would see every menu entry
and would get login page for every menu he is not allowed to.
My idea is to figure out who is logged on and then do nothing in the
index() function of each restricted module. So far I couldn't find such a
function in LuCI API (http://luci.subsignal.org/api/luci/), that would
return a current logged user.
I know how to add additional users in OpenWrt/LuCI
(https://forum.openwrt.org/viewtopic.php?pid=163013#p163013). But it is
only a part of the solution.

Data is not deleted properly after running of Spec
Data is not deleted properly after running of Spec
In my RSpec file, I have used FactoryGirl to create objects that I have
used in my RSpec file. In my RSpec file I have used three objects A, B and
C where C is dependent on B and B is dependent on A. Here in RSpec file I
have written two test cases: one for testing index method of my controller
and another for update method. So I have created the objects which I have
used to test those two methods, as follows:
before(:each) do
@A = FactoryGirl.create(:A)
@B = FactoryGirl.create(:B)
@C = FactoryGirl.create(:C)
end
And here I am using test environment of Rails, so I am using corresponding
test database which I have already. So to clean the database after
running, I have written the following code:
after(:each) do
C.all.destroy
B.all.destroy
A.all.destroy
end
But the problem is that after running the spec, while I am checking the
tables corresponding to them I find that data is not deleted. Here I have
used DataMapper in my models. So can please anyone help me to fix this
problem i.e. to clean those tables after each run of spec. Thank you.

Why do GIL alternatives have an impact on performance?
Why do GIL alternatives have an impact on performance?
Coming from Java the whole Global Interpreter Lock (GIL) in Ruby and
Python is kind of startling. I have read a bit into the problem and found
in the Python documentation the following excerpt:
Can't we get rid of the Global Interpreter Lock?
The global interpreter lock (GIL) is often seen as a hindrance to Python's
deployment on high-end multiprocessor server machines, because a
multi-threaded Python program effectively only uses one CPU, due to the
insistence that (almost) all Python code can only run while the GIL is
held.
Back in the days of Python 1.5, Greg Stein actually implemented a
comprehensive patch set (the "free threading" patches) that removed the
GIL and replaced it with fine-grained locking. Unfortunately, even on
Windows (where locks are very efficient) this ran ordinary Python code
about twice as slow as the interpreter using the GIL. On Linux the
performance loss was even worse because pthread locks aren't as efficient.
What I did not found is the explanation behind the performance impact. I
have tried to find out what the technical reasons are, but could not find
any good discussion that nails it down.
Similar in Ruby, here I could find even less information. Are the reasons
the same?

Editing grid row data on bind
Editing grid row data on bind
Is it possible to edit each line on a grid as it is binding? I'd like to
sum a series of records and have it display on one line. I'm setting it up
as a multi-sourced table with an inner and outer join. RouteVersion is the
main table with InventDim/InnerJoin and SalesLine/OuterJoin.
My ultimate goal is to Display a line for each Route per site and the
RemainSalesPhysical sum for that Route on each site. Each route is tied
one to one with an Item.
I've tried this through table methods, but since I can't access the
current grid line's fields I don't know the specific route, or site, or
item (depending on what table the method is in).
Maybe I'm going about this the wrong way, does anyone have any suggestions
for me that can put me on the right path?

Both teams are coming into the Spanish Super Cup final after great
victories at the start of the Primera, Barcelona coming from a 7:0 victory
at home against Levante, while Atletico Madrid made a great victory over
Sevilla winning them on the road with a 3:1 result. Second match will be
played at Barcelona venue seven days from now.
Atletico continued good tradition against Sevilla, as they didn't lost
against them in last eight matches and confirmed that tradition with a 3:1
victory on the road last weekend, with scoring two goals in 79th and 92nd
minute of the match. Without their star player Falcao, Atletico made a
right step into new season, while they will try to get advantage of the
positive start and try to hurt Barcelona in the Spanish Super Cup. Last
season they managed to take the third position in the championship, while
they defeated Real Madrid in the Cup's final after overtime, meanwhile
they proved to be the best defensive team in the country. Midfielder
Thiago returns after suspension in the team, while the hosts have no
injury or suspension problems in front of this game.

only. Instead of id i need to pass the AppID. Any help would be

Esper last inserted Event
Esper last inserted Event
Is there a way to get the last inserted event in esper core prior to rule
completion?
Configuration cepConfig = new Configuration();
cepConfig.getEngineDefaults().getMetricsReporting().
setEnableMetricsReporting(true);
cepConfig.addEventType("Stream", Stream.class.getName());
EPServiceProvider cep =
EPServiceProviderManager.getProvider("myCEPEngine", cepConfig);
EPRuntime cepRT = cep.getEPRuntime();
EPAdministrator cepAdm = cep.getEPAdministrator();
EPStatement cepStatement = cepAdm.createEPL("select * from
Stream.win:length(100)") ;
cepStatement.addListener(new CEPListener());
Now for event insertion i am using this sample code
for (int i = 0; i < 500; i++) {
GenerateRandomStream(cepRT);
//Here I want get the last inserted event
}
Any help will be appreciated.

Split string to the right of delimiter
Split string to the right of delimiter
I am trying to obtain the string to the right of the delimiter "|" and
anything to the left can be ignored.
I tried the following, but it gives me the values to the left
Dim s As String = "John Smith | 09F2"
Console.WriteLine(s.Substring(0, s.IndexOf("|")))
Console.WriteLine(s.Split(CChar("|"))(0))
Console.ReadKey()
Result is: John Smith. I want the 09F2 value.
I also tried the following lines of code:
Dim strEmployeeInfo As String = cmbSelectEmployee.Text
Dim employeeID = Microsoft.VisualBasic.Right(strEmployeeInfo,
strEmployeeInfo.IndexOf("|"))
But the result of that is Smith | 09F2. Again I only need the 09F2

How to parse commandline parameter that occur multiple times
How to parse commandline parameter that occur multiple times
how to parse commandline parameter for that defintion:
myjar [-hv] [[--exclude PATTERN]...] dir
It should be possible to put multiple --exclude PATTERN and define exactly
one dir.
At the end it should match to this config class:
static class CliConfig {
public boolean verbose;
public List<String> filter;
public String dir;
}
This are some valid examples:
myjar -v --exclude *.jpg --exclude *.jpeg /tmp
myjar /tmp
myjar -h
I had a look to apache-commons-cli, jcommander and args4j but I couldn't
make it running for the --exclude PATTERN. They have this "multi variable"
options just for the last parameter. Or i overread it.
I'm free in choosing any library.
P.S.: This is similar to the linux program: ncdu

Macbook Pro boots successfully when using hard drive in USB enclosure but doesn't boot when connected internally
Macbook Pro boots successfully when using hard drive in USB enclosure but
doesn't boot when connected internally
Apologies for the long question. I will keep it as simple as I can.
Last week my Macbook Pro (13-inch, Mid 2010) started to act strange.
It started when I tried to open Skype and received an error complaining
that the program could not start because Skype could not read (or lock,
unfortunately I can't remember) it's skype.plist file.
I restarted my Macbook hoping that would fix the problem (and I hadn't
restarted in a while so I figured it was overdue).
My Macbook restarted and played the startup chime but then hung at the
grey startup screen with the spinning wheel. I thought nothing of it and
did a hard shutdown but no matter how many times I did, the Macbook never
advanced past the grey startup screen.
I tried to boot using Safe and Verbose mode and got the following error in
both cases:
BootCacheControl : Unable to open /var/db/BootCache.playlist: 22 invalid
argument
I googled the error and tried various solutions with no luck.
The Macbook would boot to the built-in Mountain Lion recovery partition.
At this point I decided to backup my data so I could mess with the hard
drive a bit more without fear of losing any data. I booted in to the
recovery partition and cloned my hard drive onto another using a USB
enclosure. It seemed to work OK and I verified all of my files were on the
backup hard drive by plugging it into another Macbook.
After cloning my hard drive I verified and repaired the disk and disk
permissions using the disk utility in the recovery partition but that had
no effect.
At this point I decided to reinstall Mountain Lion. I tried numerous times
to reinstall it with the hard drive inside the Macbook (both using the
recovery partition and a bootable Mountain Lion SD card) but couldn't get
it to install. Eventually I got it to install, but only when the hard
drive was placed in a USB enclosure. I knew this probably indicated a
bigger underlying problem but decided to go ahead anyway.
I installed Mountain Lion successfully but now it will not boot with the
hard drive connected inside the Macbook, only when it is used in my USB
enclosure. When the hard drive is placed in my USB enclosure it boots to
Mountain Lion without any problem.
With the hard drive inside the Macbook:
If the Macbook is booted as standard, it hangs on the grey startup screen
with spinning wheel
If it is booted in verbose mode, it seems to boot successfully (shows no
errors when the white text show up) and then hangs on a black screen with
a solid white cursor in the top left corner (I can type at this point but
it does nothing, it doesn't appear to be a terminal window)
If it is booted in safe mode, the progress bar appears, progresses to the
end and then hangs on the grey startup screen with spinning wheel
I noticed a lot of suggestions on the internet to replace the hard drive
cable to the motherboard. I did and it had no effect.
I've tried using another hard drive running a brand new install of
Mountain Lion and that behaves exactly the same (boots fine using a USB
enclosure but doesn't boot when connected internally).
I've booked an appointment at the Apple store but figured it was worth
posting the question anyway, in case anybody has a similar issue in the
future (hopefully I'll be able to post the answer, if nobody else does,
after a visit to the Genius bar).
Any suggestions?
Thanks for reading.

This programs takes a long time to close after the 'return;' on main()
This programs takes a long time to close after the 'return;' on main()
This is the code I am dealing with:
#include <iostream>
#include <map>
using namespace std;
static unsigned long collatzLength(unsigned long n) {
static std::map<unsigned long,int> collatzMap;
int mapResult = collatzMap[n];
if (mapResult != 0) return mapResult;
if (n == 1) {
return 1;
} else {
collatzMap[n] = 1 + collatzLength(n%2==0?n/2:3*n+1);
return collatzMap[n];
}
}
int main() {
int maxIndex = 1;
unsigned int max = 1;
for (int i=1; i<1000000; i++) {
//cout<<i<<endl;
unsigned long count = collatzLength(i);
if (count > max) {
maxIndex = i;
max = count;
}
}
cout<<maxIndex<<endl;
getchar();
cout<<"Returning..."<<endl;
return maxIndex;
}
When I compile and run this program (using Visual Studio 2012 and Release
build settings) it takes like 10 seconds (on my computer) to close after
the program prints "Returning..."
Why is that?
Note: I am aware that this program is bad written and that i probably
shouldn't be using 'static' on the collatzLength nor using a cache for
that function, but I am not interesting on how to make this code better, I
am just interesting about why does it take so much to close.

Search function mixed with json and php (sql)
I write a search system, this system has 4 pages/steps, on the first 3
pages are only checkboxes to find, my problem is, i create this checkboxes
per json, and i can read only names. To convert this data for checkboxes i
use:
<?php
$jsonData = json_decode($string5, true);
foreach ($jsonData as $item) :
?>
<label><input type="checkbox" name="<?php echo $item['name'] ?>" value=""
/><?php echo $item['name'] ?></label><br />
<?php
endforeach;

My questions are: How can i get values from checkboxes on the page/step 4
dynamicly? How can i from this json data create a sql query for search
results?

Cakephp generated javascript throws error onclick
Cakephp generated javascript throws error onclick
I have a group of tests in my system. It is possible for a test to be
paused. On the index page of my test controller, I use the following code
to display the tests.
<table>
<tr><th>ID</th><th>Name</th><th>Updated</th><th>Actions</th></tr>
<?php foreach ($tests as $test): ?>
<tr>
<td>
<?php echo $test['Test']['id']; ?>
</td>
<td class="actions">
<?php
$status = ($test['Test']['is_paused'] == 1) ? 'Un-pause' :
'Pause';
echo $this->Form->postLink($status,
array('controller'=>'tests', 'action' => 'pause',
$test['Test']['id'], 'admin' => 1), array('confirm'=>'Are you
sure?') );
?>
<?php
echo $this->Html->link('Edit', array('controller'=>'tests',
'action' => 'edit', 'admin'=>1, $test['Test']['id']));
?>
<?php
echo $this->Form->postLink('Delete',
array('controller'=>'tests', 'action' => 'delete',
$test['Test']['id'], 'admin'=>1), array('confirm'=>'Are you
sure?') );
?>
</td>
</tr>
<?php endforeach; ?>
</table>
This generates a list of tests and provides some action functions for each
one using postlink from the cakephp form helper. The one that is causing
problems is the pause button. Sometime when clicked it throws the
following error.
Uncaught TypeError: Object #<HTMLCollection> has no method 'submit'
I'm not super up on my JS and since the JS for this is automatically
built, I'm not sure how to fix this. The pause button will do nothing when
this issue occurs and I'm not even sure where to start debugging this.
Thank you to anyone who helps.

AS3 Mouse down not working
AS3 Mouse down not working
I have a button that has been added to the stage. When it is created, it
moves into the visible area of the stage, and calls an activate function,
which adds an event listener to it that looks for mouse down. For some

adding a listener to the object via the one that created it, but that
doesn't work either.

Arquillian Embedded Glassfish Certificate Expired
Arquillian Embedded Glassfish Certificate Expired
On Aug 14th, the gtecybertrust5ca certifcate used by Glassfish expired
causing my Arquillian tests that use an embedded Glassfish server to all
fail. I have verified I am using the latest JDK, 1.7.0_25-b17, and my
Maven libs are current.
This problem is similar to this one: Certificate has expired" in log by
starting Glassfish 3.1.2 except, I am using the Embedded version of
Glassfish via Maven, Arquillian and SureFire to run unit and integration
tests.
I have tried instructing Maven to use a local keystore, the one that comes
with the JRE, in an effort to keep the expired cert from being used.
Unfortunately, this didn't help either. Using the Maven debug flag, I can
see that the JDK is forked with the addition arguments.

</plugin>
I have also tried downloading the actual Glassfish server, exporting its
certificates gtecybertrust5ca and gtecybertrustglobalca from the keystore
at glassfish4\glassfish\domains\domain1\config\cacerts.jks and then
imported them into my JRE keystore marking them as trusted. This also
didn't work:
keytool -exportcert -keystore cacerts.jks -alias gtecybertrustglobalca
-file gtecybertrustglobalca.crt keytool -exportcert -keystore cacerts.jks
-alias gtecybertrust5ca -file gtecybertrust5ca.crt

Laptop connects to wrong wireless network
Laptop connects to wrong wireless network
I mostly have two wireless networks in range NP_LNK (low signal strength,
OPEN, owned by my nieghbour) and MY_LINK(Strong signal strength ,
Protected by a KEY, Owned by me)
and My laptop always connects to NP_LINK automatically. I have tried
deleting this network and changing settings but it appears again on next
boot.
Is there a way to permanently hide/ disable this network ?

How do I submit POST for cURL in Lithium
How do I submit POST for cURL in Lithium
I'm trying to create a custom Auth adapter for a legacy API. Let's call
the adapter TR42. Right now, I'm debugging TR42::check() so I'm using
hardcoded values:
<?php
class TR42 extends \lithium\core\Object {
public function __construct(array $config = []) {
$defaults = [
'scheme' => 'http',
'host' => 'localhost/tr42/mock_api_authenticate.php',
'action' => 'authLookup',
'fields' => ['username', 'password'],
'method' => 'POST'
];
parent::__construct($config + $defaults);
}
public function check($credentials, array $options = []) {
$postConfig = [
/**
* Should I be using 'body' or 'query' to submit POST fields?
*/
'body' => [
'username' => 'housni',
'password' => sha1('legacyHashedPassword'),
'action' => 'authLookup'
],
'query' => 'username=housni&password=' .
sha1('legacyHashedPassword') . '&action=authLookup',
];
$request = new Request($postConfig + $this->_config);
$stream = new Curl($this->_config);
$stream->open();
$stream->write($request);
$response = $stream->read();
$stream->close();
echo '<pre>' . print_r($response, true) . '</pre>';
die();
}
}
?>
The file http://localhost/tr42/mock_api_authenticate.php looks like this:
<?php
echo '<h1>This request is: ' . $_SERVER['REQUEST_METHOD'] . '</h1>';
if (!empty($_POST)) {
echo '<h1>YAY</h1>';
} else {
echo '<h1>NAY</h1>';
}
echo '<pre>' . print_r($_POST, true) . '</pre>';
?>
Since my cURL code submits a POST request, I'd expect my $_POST to be
populated in mock_api_authenticate.php but that's not happening because
the output from TR42::check()'s print_r() is:
HTTP/1.1 200 OK

It's saying the request is POST but the POST array (the last empty array)
is empty.
What am I doing wrong?

Linux boot drive refusing to reset
Linux boot drive refusing to reset
I used one of my USB sticks to create a live ubuntu disk intending to
clear it later, well I plugged it in to Linux Mint 15 today only to find
that I can not delete any of the files on it.
Is there a way to delete those files? Or is it just stuck forever? I also
tried putting it on windows only it was even worse there only allowing me
to see only 2.19 mbs of the total 16 gig drive. I was hoping that deleting
that would fix it once I got back to linux, it however did not.
Thanks for answering! I really need help on this one.

What determines what resolutions a laptop is willing to output over VGA?
What determines what resolutions a laptop is willing to output over VGA?
I'm responsible for several conference rooms and have setup 1080p
projectors and I provide both HDMI and VGA connectivity. HDMI for
DisplayPort and Mini-DisplayPort, and VGA as a fallback, universal option.
Contrary to what I expected, people seem to have much more trouble with
the HDMI than VGA, so VGA gets used a lot more than you'd think (even as
most workstation laptops made in the last 3-4 years have DisplayPort or
Mini-DisplayPort...). Also to my surprise, VGA outputs over 1080p on a
50ft cable run with very minimal degradation on certain laptops - other
laptops just don't offer 1080p as a resolution choice and top out at
1600x1200 or something else. Specific example: a ThinkPad W530 will do
1080p, a W520 won't, over VGA.
What determines what resolutions a laptop is willing to output over VGA?
I'm thinking this will come down to either a video driver that says it
supports only certain resolutions for output, or limitations of the RAMDAC
(which wouldn't be in play, at least DAC wise, on a digital output, but
WOULD on VGA, an analog output).
The basic reason for the question is that I noticed, say, a ThinkPad W520
with 1080p built in display, will output 1080p fine over DisplayPort to a
1080p projector, but will cap out at 1600x1200 (practically the same pixel
count, just a little shy) on VGA. Now, this wouldn't be surprising at all
except SOME laptops have no issue outputting 1080p over VGA, even with
lower native resolutions.
Why do I care? Well if there's some way I could enable it... for
situations where my users end up using VGA anyway, it's preferable for
display mirroring if they can output their laptop's native resolution,
which, you guessed it, is very often 1080p on 15" models.
DISCLAIMER: This is primarily a curiosity, I'm not claiming 1080p over VGA
is ideal by any means, but hey, if it works. I've seen HDMI start
artifacting more over same-length, same gauge cabling (up to 50' run in
certain rooms). If you think this is better suited to SuperUser, please
move it, but this is framed from an IT standpoint of something that
affects a real pool of users in a multiple conference room, 50+ deployed
laptop scenario.
