Why can a matrix 'protect' itself and how can I implement real
restrictions to custom classes?
I have been trying to get my ahead around validity of objects. I have read
Hadley's advanced programming and get what he says about he says about
aiming at your feet (with a gun):
"R doesn't protect you from yourself: you can easily shoot yourself in the
foot, but if
you don't aim the gun at your foot and pull the trigger, you won't have a
problem"
So this holds for S3. Looking for a more rigorous implementation I looked
into S4. The man page to setValidity brought up the following:
setClass("track",
representation(x="numeric", y = "numeric"))
t1 <- new("track", x=1:10, y=sort(stats::rnorm(10)))
## A valid "track" object has the same number of x, y values
validTrackObject <- function(object) {
if(length(object@x) == length(object@y)) TRUE
else paste("Unequal x,y lengths: ", length(object@x), ", ",
length(object@y), sep="")
}
## assign the function as the validity method for the class
setValidity("track", validTrackObject)
## t1 should be a valid "track" object
validObject(t1)
## Now we do something bad
t2 <- t1
t2@x <- 1:20
## This should generate an error
## Not run: try(validObject(t2))
Bottom line: If I do not add validObject to the initializer or constructor
there's little I can do. Also this post from Martin Morgan and
bioconductor's Seth Falcon was interesting, still though I could always
t2@x <- 1:1111.
I guess there's not much I can do about this? Though the matrix class for
example makes me wonder if there's an option.
a <- matrix(c(1:12),3,4)
cbind(a,"somechar")
# or similarily
a[1,1] <- "b"
Obviously all elements of a matrix have to be of the same class. So that's
why once a character is added all elements are coerced to the common
denominator, which is class character.
So my question is: How is this possible? In which way is the matrix class
defined, that it can protect the restriction "some class for all elements"
by any means? And is there a way to implement such a restriction to a
custom class, too?
E.g.: class of class 'customlist' that has to be a named list and names
being restricted to only be two chars long.

importing 20k details in php using csv
importing 20k details in php using csv
I'm trying to insert a csv file with at least 20k lines, and it prompts my
browser to kill it self, I guess its taking up a lot of memory and its
processing it really slow, I'm also doing this for export and still the
same problem it takes too much time that the browser wanna kill it self.
Do you have any suggestions on how am I supposed to make it easier and

Web client works on GlassFish 4, but not on GlassFish 3
I'm developing some enterprise web site using Java EE 6 technology. My
collegue was assigned working on web client and he develops it on his PC
using JSF 2.1 and GlassFish 4.0. When I tried running that web client on
my PC, which at first had GlassFish 3.1 instaled, it didn't work. Not a
single line of xhtml code was rendered on my web browser.
Later on, I installed GlassFish 4 and deployed application on it and look
at miracle - it worked! So basicaly, my question is simple: Why does that
happend? Why can't I run web client on older version of GlassFish server?
P.S. No error or warning is recorded on server's log when I try to run it
on GlassFish 3.1.

Closed form of the limit of a sequence (weighted average)
Closed form of the limit of a sequence (weighted average)
I have a sequence, which can actually be seen as Riemann-Stieltjes
integration with a binomial distribution. $\rho \in (0,1)$.
$$ S_N
:=‡"_{n=0}^{N}ƒÏ^{N-n}(1-ƒÏ)^{n}\binom{N}{n}\left(\frac{n}{N}\right)^\theta
$$
Using convexity/concavity of $(n/N)^\theta$ I can show the sequence
declines/increases with N. The sequence is also bounded between 0 and 1. I
wonder if there is a closed form limit of this sequence.
I appreciate any thoughts on this.

Is it possible to install Microsoft Office without a CD?
Is it possible to install Microsoft Office without a CD?
I have been a Windows user since... well... always. Now I decided to try
Linux Ubuntu, and found out it looks way much better.
The problem is, I am a student and constantly need Microsoft
Word/Excel/Powerpoint, and LibreOffice just isn't the same thing. When I
have to update something on Excel, when I open the same archive on Windows
some formatation of it is changed. That's why I would like to install
Microsoft Windows.
I do not have the installation CD. However, I already have the Microsoft
Office installed on Windows. I have tried the convenient methods to
install it through PlayOnLinux, but I keep stuck on this part
http://i.stack.imgur.com/2GPmT.png
From:Can Wine support Office 2007?
My question is: Can I install it through the archives it created on
Windows when it was there installed or would I really need the CD for that
and, therefore, not being able to install? Would I be able to borrow a CD
from someone?
Thank you.

Word/Excel/Powerpoint, and LibreOffice just isn't the same thing. When I
have to update something on Excel, when I open the same archive on Windows
some formatation of it is changed. That's why I would like to install
Microsoft Windows.
I do not have the installation CD. However, I already have the Microsoft
Office installed on Windows. I have tried the convenient methods to
install it through PlayOnLinux, but I keep stuck on this part
http://i.stack.imgur.com/2GPmT.png
From:Can Wine support Office 2007?
My question is: Can I install it through the archives it created on
Windows when it was there installed or would I really need the CD for that
and, therefore, not being able to install? Would I be able to borrow a CD
from someone?
Thank you.
Null bytes when using xlwt to make valid excel file
Null bytes when using xlwt to make valid excel file
I'm using Python 2.7 and attempting to automate downloading an excel file
from a website using the mechanize library. I used CharDet to discover the
original encoding for the file, which is "iso-8859-2". In order to
properly separate the data into columns based on the data read by
mechanize, I have an intermediary step storing the data to a text file.
fileobj = open("data.txt", 'wb')
fileobj.write(response.read())
fileobj.close()
To create the Excel file, I am using the xlwt module.
book = xlwt.Workbook(encoding = "utf-8")
sheet = book.add_sheet('sheet1')
After this, I read through the text file and attempt to decode the text
and encode it into utf-8 form with
for line in fileobj:
line = line.decode("iso-8859-2").encode("utf-8", "ignore")
The problem is that attempting to iterate over the file using Python's csv
default reader reports an error that there are null bytes. Placing the
encoded text in a .txt file shows there are no null bytes in the lines
themselves, so I am not sure where the problem is coming from.

R language: Maximize function subject to another function
R language: Maximize function subject to another function
I am interested to know how can I maximize a function f(x) = x/y subject
to x + y = 100 using R. I know a couple of packages like optim or optimize
that helps to do it but it requires a vector of values for the parameters
to be optimized over. I would like to know if I could do it without the
use of the values.
Any advice or help would be appreciated.
Thanks !!

SQL Truncate Error when Inserting UUID
SQL Truncate Error when Inserting UUID
I'm building a database driven PHP application that uses UUID's to store
each row of data. The application currently generates the UUID's using the
following query:
SELECT UUID()
which generates an output similar to 84058227-294c-11e3-916a-7a7919b2b2bc.
Many online sources suggest that UUID's be stored in BINARY(16) to improve
overall application performance. But when I attempt to insert the UUID
into the database, I receive the following error:
Warning: #1265 Data truncated for column 'x' at row x
I realize that this error occurred because the UUID was too large for the
column to store, and that this issue can be easily fixed by simply
increasing the amount of characters the column may store (ex: BINARY(20)),
but I fear that doing so may reduce the application's performance in the
future.
Considering that so many online sources suggest using BINARY(16) to store
UUID's, I'm assuming that I have made a mistake.
Could someone please point me in the right direction?
For extra information, here is the code I'm using (in PHP) to insert data
into the database:
//PDO Query
$this->query(
INSERT INTO users
(
user_id, //the UUID is stored in this column
taxonomy_id,
user_email,
user_password,
user_salt,
user_activation_key,
user_is_administrator
)
VALUES(?,?,?,?,?,?,?)
',
array(
$this->uuid(), //method that generates UUID
$taxonomy_id,
$user_email,
$user_password,
$user_salt,
$user_activation_key,
$user_is_administrator
)
)
);
and the method that generates each UUID:
public function uuid()
{
$uuid = $this->query("SELECT UUID() AS uuid");
return $uuid[0]['uuid'];
}

Adding columns to a data table
Adding columns to a data table
I have a data.frame (or a matrix or any other tabular data structure
object for that matter):
df = data.frame(field1 = c(1,1,1),field2 = c(2,2,2),field3 = c(3,3,3))
And I want to copy part of its columns - given in the vector below:
fields = c("field1","field2")
to a new data.table that already has 1 or more columns:
dt = data.table(fieldX = c("x","x","x"))

In my iPad app (XCode 5, ios7, ARC, Storyboards), I'm trying to read the

Composition of objects vs functions: Should I use one method interfaces or delegates?
Composition of objects vs functions: Should I use one method interfaces or
delegates?
C# is a multi paradigm language. With nesting interfaces and classes one
can get a composition of objects. This way a certain problem can be broken
down to a number of simple ones giving each component its own piece of the
puzzle to solve. The same trick can be done in a slightly different
manner, one can make a composition of functions each of which is
responsible of solving its own little task while all combined and
interconnected they give the answer to the main problem.
Following SOLID principles I found myself in a situation where 95% of my
interfaces carry just one method named do-something and the name of the
interface is something-doer. The class that implements such interfaces is
DI'ed with the a few components required to fulfill whatever that method
is supposed to do. Such approach is basically making a closure over a
function by hands. If so, why wouldn't I just go with delegates that do it
naturally and for free (no typing necessary)? If I go all the way
converting single method interfaces to delegates I will eliminate 95% of
them from my code making it look like written in functional language. But
this seems like a right thing to do unless there is some bold reason to
stick with interfaces. Is there?
delegates?
C# is a multi paradigm language. With nesting interfaces and classes one
can get a composition of objects. This way a certain problem can be broken
down to a number of simple ones giving each component its own piece of the
puzzle to solve. The same trick can be done in a slightly different
manner, one can make a composition of functions each of which is
responsible of solving its own little task while all combined and
interconnected they give the answer to the main problem.
Following SOLID principles I found myself in a situation where 95% of my
interfaces carry just one method named do-something and the name of the
interface is something-doer. The class that implements such interfaces is
DI'ed with the a few components required to fulfill whatever that method
is supposed to do. Such approach is basically making a closure over a
function by hands. If so, why wouldn't I just go with delegates that do it
naturally and for free (no typing necessary)? If I go all the way
converting single method interfaces to delegates I will eliminate 95% of
them from my code making it look like written in functional language. But

How to get the DeleteParameter value in to the Code behind?
How to get the DeleteParameter value in to the Code behind?
I have a ListView that enables deleting, I also use SQLDatasource as
DataSource of the ListView, I have these 2 tables:
News table that contains news_id, title, etc.. and
Feedback table that contains feedback_id, comment, news_id(FK), etc...
I can delete a record that doesn't have comments but I get this error when
I try to delete a News that has a comments, the comments is from the table
'Feedback' that has a foreign key 'news_id' from the table 'News', I know
that to resolve this is I need to delete the records from the Feedback
table first. How can I achieve it? I'm thinking of using OnItemDeleting
Event in ListView and execute a query:
DELETE FROM Feedback WHERE news_id = @news_id
and then it can proceed to execute the DeleteCommand in the SQLDataSource
that is:
DeleteCommand="DELETE FROM [News] WHERE [news_id] = @news_id"
but then I got this error:
Must declare the scalar variable "@news_id".
this is my DeleteParameter:
<DeleteParameters>
<asp:Parameter Name="news_id" Type="Int32" />
</DeleteParameters>
how can i get the news_id from the DeleteParameter? any answer is
appreciated, thanks.

Using loops to compute factorial numbers, Java
Using loops to compute factorial numbers, Java
I'm trying to compute the value of 7 factorial and display the answer, but
when I tried to look up a way to do this I kept finding code that was
written so that a number first had to be put in from the user and then it
would factor whatever number the user put in. But I already know what
number I need, obviously, so the code is going to be different and I'm
having trouble figuring out how to do this.
I tried this at first
public class Ch4_Lab_7
{
public static void main(String[] args)
{
int factorial = 7;
while (factorial <= 7)
{
if (factorial > 0)
System.out.println(factorial*facto…
factorial--;
}
}
}
But all it does is display 7*7, then 6*6, then 5*5, and so on, and this
isn't what I'm trying to do. Does anyone know how to do it correctly?

How to find value of an attribute in a sub child node of an XML?
How to find value of an attribute in a sub child node of an XML?
I have a XML which has the following structure:

<TestResultAggregation testName="MyOrder">
<Counters error="0" failed="1" timeout="0" aborted="0" inconclusive="0"/>
<InnerResults>
<UnitTestResult testName="TestMethod3" outcome="Failed">

</StackTrace>
</ErrorInfo>
</Output>
</UnitTestResult>
<UnitTestResult testName="TestMethod2" outcome="Passed">
<Output>
</Output>
</UnitTestResult>
</InnerResults>
</TestResultAggregation>
When the result of 'outcome' attribute in 'UnitTestResult' is 'failed', I
have to display the value of 'ErrorInfo' and 'StackTrace' nodes too. The
catch here is that the above schema is not fixed. For eg,

Replacing special chars in a string with a single unique char
Replacing special chars in a string with a single unique char
I have a string like so:
string inputStr = "Name*&^%LastName*#@";
The following Regex will replace all the special chars with a '-'
Regex rgx = new Regex("[^a-zA-Z0-9 - _]");
someStr = rgx.Replace(someStr, "-");
That produces an output something like: Name---LastName---
How do I replace '---' with a single '-' so the output looks like this:
Name-LastName
So the question is how do I replace all the special chars with a single '-'?
Regards.

Apply Column Filtering in Gridview in asp.net
Apply Column Filtering in Gridview in asp.net
I have a gridview which is populated at runtime with a table with unknow
number of columns which are not known before hand.
I want to apply column filtering on all columns with Drop Down List.
How can I achieve it. Using Jquery, Linq or simple C sharp Coding.
Any help be highly appreciated

Beginner Java Program to repeat user phrase
Beginner Java Program to repeat user phrase
My first post, so be gentle.
I am in an Intro to Programming class. We are covering loops after doing
the variables, classes, getters/setters, and constructors. I understand
how loops work. However, My confusion is in the directions. I have the
bare bones set up, but the instructions confuse me as I am trying to
figure out putting a method within another (if I understand correctly).
The directions are as follows:
UML Class Diagram: Learning Outcomes: „h Declare a class that is intended
to be instantiated „h Declare a method to provide a functionality „h
Create an instance of the class you declared „h Access the method using
the dot operator „h Increase your familiarity with UML class diagrams „h
Review the use of Scanner „h Create a project called LabParrot „h Add 2
files to the project: Parrot.java and ParrotTest.java „h In Parrot.java do
the following: „X Create a public class called Parrot „X Inside the class
create a public method called speak. The method speak has one String
parameter named word and no return value (i.e. return type void) The
method header looks like this: public void speak(String word) „X The
parrot repeats anything he is told. We implement this behavior by printing
the word passed as an argument. „h In ParrotTest.java create the main
method Inside the main method do the following: „X Create an instance of
Scanner named input „X Create an instance of Parrot named myParrot You
create a new instance by calling the default constructor like this: Parrot
myParrot = new Parrot(); „X Read in a text (i.e. use Scanner to let the
user choose what s/he would like to say to the parrot); make sure to
prompt the user before you read in the text Create a String variable
called text to temporarily store the input read „X Call the method speak
of the instance myParrot and pass the variable text as argument NOTE: the
variable name passed does not have to match the parameter name The method
call looks like this: myParrot.speak(text); Sample Output1: What would you
like to say to the parrot? hi hi Sample Output2: What would you like to
say to the parrot? how are you? how are you?
My code so far is this:
import java.util.Scanner;
public class LabParrot {
//begin method public void static void(String [] args) {
//set up variables
char String = word;
Scanner input = new Scanner(System.in);
//Obtain user input
System.out.println("What would you like to say to the parrot?");
word = input.nextLn();
}
}
Did I put everything in the correct place so far? Sorry if this seems
silly. I don't have too many similar examples to this assignment to figure
it out.

JoGL not drawing within a loop
JoGL not drawing within a loop
I have working on an OBJ model loader in JoGL for a few days, and can
obtain the vertices in the array draw: draw[face][vertex][x,y,z,or w] I
have tried several ways to render this array (i.e. VBO's) but none have
worked so far. I decided to attempt to render the face within a loop,
however, when I run the program nothing is rendered. Here is my code:
for(int i = 0; i < draw.length; i++){
gl.glBegin(GL.GL_TRIANGLE_STRIP);
//start drawing
for(int i2=0;i2<draw[i].length;i2++){
float[] xyzw = new float[4];
//grab all the vertex values
for(int i3=0; i3<draw[i][i2].length;i3++){
xyzw[i3]=draw[i][i2][i3];
}
gl.glColor3f(1.0f, 0.0f, 0.0f); // Set the current
drawing color to red
gl.glVertex3f(xyzw[0], xyzw[1], xyzw[2]);
}
gl.glEnd();
}
The peculiar thing is if I do this:
for(int i = 0; i < draw.length; i++){
gl.glBegin(GL.GL_TRIANGLE_STRIP);
//start drawing
for(int i2=0;i2<draw[i].length;i2++){
float[] xyzw = new float[4];
//grab all the vertex values
for(int i3=0; i3<draw[i][i2].length;i3++){
xyzw[i3]=draw[i][i2][i3];
}
gl.glColor3f(1.0f, 0.0f, 0.0f); // Set the current
drawing color to red
gl.glVertex3f(xyzw[0], xyzw[1], xyzw[2]);
gl.glVertex3f(0.0f, 0.0f, 0.0f); // Top
gl.glColor3f(0.0f, 1.0f, 0.0f); // Set the current
drawing color to green
gl.glVertex3f(1.0f, 0.0f, 1.0f); // Bottom Left
gl.glColor3f(0.0f, 0.0f, 1.0f); // Set the current
drawing color to blue
gl.glVertex3f(0.0f, 0.0f, 1.0f); // Bottom Right
}
gl.glEnd();
}
then I get a contorted shape, however without those extraneous vertices
nothing is rendered.

How to set a String ViewModel property on ReadioButton Check usin WPF?
How to set a String ViewModel property on ReadioButton Check usin WPF?
I am new to WPF and here I am trying to set a simple string property of my
viewModel when a particular radio button is checked on my window.
class ViewModel
{
string LanguageSettings
}
XAML looks like following:
<RadioButton Name="OptionEnglish" GroupName="LanguageOptions"
IsChecked="{Binding LanguageSettings}" Content="English"
HorizontalAlignment="Right" Width="760" />
<RadioButton Name="OptionChinese" GroupName="LanguageOptions"
IsChecked="{Binding LanguageSettings}" Content="Chinese" />
All I want here is that when English is selected I want Language Settings
to be set as English and same for Chinese. Is there any simple way to do
it? I also looked into some IValueConverter examples. Do I really need to
do that? is there any straightforward way to set that property?

jQuery increasing and decreasing div height based on scroll positioning

jQuery increasing and decreasing div height based on scroll positioning.
Was wondering if any of you know of any way to do this in a good way.
Let's say i have a div with and id of "scroll-element" And when i scroll
down the page, let's say down like 500px it starts to increase to about
200px when scrolling down and decreasing to 0px when i scroll back up. I
tried a few methods but none have worked so far.

Math library against own library in C#
Math library against own library in C#
So we tried developing a math class in C# and we did. Comparing results
with the original math class for System.Math shows that we are always late
a little or a lot (trig methods particularly).
But the wonder comes when we are using basic methods like Absolut value
which does not contain loads of code apart from
if(value < 0) return -value;
else return value;
and still we are far behind.
I cannot make this abs method any smaller, using the ternary operator will
not help either I guess.
Is it because the System.Math would be written in C? Would it go faster if
we write it in native language, though it seems it won't change much I
read. Finally, could a dll work faster than a class and if so why and if
not ...well why too?
Thanks already.

How does this curl command differ from my php code?
How does this curl command differ from my php code?
I am simply trying to duplicate this curl command in PHP:
curl -X POST -H 'Content-Type: application/xml' -u username:password
https://api.company.com/api/path
This is the PHP code I am using:
$ch = curl_init("https://api.company.com/api/path");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/xml"));
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch); // $response is null
$info = curl_getinfo($ch); // $info['http_code'] is 400
While my shell command is successful and I get data back from the server,
this PHP code fails -- the server returns a 400 error. As far as I know,
the PHP code and the shell command are effectively identical, so what's
the difference I am missing?

Unfocus on all JTextFields
Unfocus on all JTextFields
How do i change the focus to be on a different JTextField? Currently when
my application loads, it is picking (what appears to be) a random
JTextField to set focus to!
I've tried
text.setFocusable(true);
text.requestFocusInWindow();
text.requestFocus(true);
text.requestFocus();
but no luck here. I've also tried How to UnFocus a JTextField but i
haven't had any luck with this working either.
The reason why I would like to not focus on the JTextFields is to avoid
the hints from not appearing when the application first loads. See image:
As you can see from the image, there is no hint on one of the JTextFields...
Any ideas? Thanks in advance..

Rotating camera around an off center sprite
Rotating camera around an off center sprite
I am making a 2d top down game. When the user moves their mouse I want the
sprite to basically point to the mouse. I was able to get that part
working if the sprite is in the center of the screen it works fine.
My problem is I want the sprite to be in the lower fourth of the screen
So what I have tried is setting the camera to the players position
rotating it and then moving it back to having the player at 1/4 of the way
up the screen but in that he case he just orbits the center of the camera
instead of the camera rotating around him.
This is my code so far that I have worked out.
mouseX = Gdx.input.getX();
mouseY = Gdx.input.getY();
Vector3 mouse = new Vector3(mouseX, mouseY, 0);
Main.cam.unproject(mouse);
Vector3 pos = new Vector3(currx, curry, 0);
pos.sub(mouse);
vec.set(pos.x, pos.y);
angle = vec.angle();
Main.cam.position.set(currx, curry, 0f);
float camAngle = -getCameraCurrentXYAngle(Main.cam)+180;
e.setRotations(angle);
setPosition(currx, curry);
Main.cam.rotate((camAngle - angle)+180);
s_.setRotation(angle);
Main.cam.position.set(currx, curry+(Main.VIEWPORT_HEIGHT/4), 0f);
public float getCameraCurrentXYAngle(OrthographicCamera cam){
return (float)Math.atan2(cam.up.x,
cam.up.y)*MathUtils.radiansToDegrees;

What's the standard way of implementing an automaton with not-transitions?
What's the standard way of implementing an automaton with not-transitions?
The naive implementation of a FA would have the node look like:
struct Node {
string label;
Node*[char] trans;
}
But what if one of your transitions is "![a]" (anything but the char 'a').
And your alphabet is too huge to store all possible chars that are not
'a'. Do you see what I mean?

Why doesn't this produce ambiguous implicit error?
Why doesn't this produce ambiguous implicit error?
I expected this code to fail with "error: ambiguous implicit values",
however it does in fact compile and run:
object AmbiguousImplicitsShouldntCompile extends App {
class A {def x = 1}
class B extends A { override def x = 2}
def f(implicit i: A) = i.x
implicit val a = new A
implicit val b = new B
println(f) // prints 2
}
Is this a bug in scala? Or is this correct behavior? I tried reading the
Scala Language Specification for anything relevant, but the parts on
implicit parameter resolution and overloading resolution are quite dense.

uses the async-twitter library to connect/authorize with twitter.
How can I turn the following code into a mobile compatible site so it does
the following:
1) Works with Safari on iOS (Apple Devices)
2) Is centered on mobile devices instead of being off center...

Want to show the domain with full page url without shoing the forwarded domain
Want to show the domain with full page url without shoing the forwarded
domain
I'm forwarding a domain to another using IFRAME. so what ever the link is
it shows only the domain, not the path. Is it possible to show the path in
this case?? I only want to hide the domain on which the site is hosted and
want to show the domain which I'm forwarding.
ex: newdomain.com forwarding to olddomain.com now its showing
newdomain.com all time. But I want to show the path of the page after
newdomain.com in url

Kendo grid group header customize to show the value and more
Kendo grid group header customize to show the value and more
I have a Kendo grid that is groupable. The initial display needs to show
all data items with no groupings displayed, i.e no 'group' and
'groupHeaderTemplate' are defined.
The grid contains a column (Suspension) where the value displayed is a
translated dataitem value, i.e. if value > 10, display '*'.
When the user drags the Suspension column header cell to group, how can
you customize the group header to show the value that it is grouping on
plus the display 'value', i.e. 10-* ?

Performing Analytics over Cassandra DB
Performing Analytics over Cassandra DB
I am working for a small concern and very new to apache cassandra.
Studying about cassandra and performing some small analytics like sum
function on cassandra DB for creating reports. For the same, Hive and
Accunu can be choices.
Datastax Enterprise provides the solution for Apache Cassandra and Hive
Integration. Is Datastax Enterprise is the only solution for such
integration. Is there any way to resolve the hive and cassandra
integration. If so, Can I get the links or documents regarding the same.
Is that possible to work the same with the windows platform.
Is any other solution to perform analytics on cassandra DB?
Thanks in advance .

Pass URL as parameter in silex controller
Pass URL as parameter in silex controller
I want to pass a url as parameter to a controller as like below:
$api->get('/getfile/{fileurl}', function(Request $request, $fileurl){
//do something
}
Here {fileurl} can be a valid http url. However, the above mapping isn't
working and resulting 404(may be because of the slashes in the {fileurl}
part?) . How to solve it to accept the $url in $fileurl variable?

Creating new instance of esri map
Creating new instance of esri map
I have an esri arc gis map. I create my map div, load that data to the map
via an ajax call. On a hyper link the jquery dialog is opened and the map
and data is loaded in there. Works great until I close and open a new
link. The same map appears and nothing changes.
V is the line number passed in from the hyper link. On each click of a new
hyper link V is changing but the map data isnt. In my dialog on the close
event i reloaded the whole page while this worked it was inefficient. The
best solution i've seen is using the map.destroy method but any time I put
that in the code it destroys the map before it even opens. Let me know if
you need anything else.
Thanks
Here is the code:
function loadData(v)
{
var varId = v;
var regType = 1;//MSA
var d =
{
varId: varId,
regionType: regType,
};
$("#loading").show();
$.ajax({
type: "GET",
url: WebRoot + "ws/GIS.asmx/CensusData",
data: d,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
fipsData = data.d;
openBox(v, d);
init(varId);

OOP and Persistence
OOP and Persistence
In the spirit of ask don't tell and never let an object get into an
invalid state oop design, I'm wondering how persistence would be handled
in a dynamic environment.
For a contrived example, imagine you need to write a POS application for
an airline. You can only sell seats that are available. Seats are grouped
such that plane -> sections -> rows -> seats. If a section is unavailable
then all rows and therefore seats in that section are also unavailable.
And obviously if a row in unavailable then all seats in the row are also
not available.
Now the environment is highly dynamic in that maintenance personnel may be
making sections, rows, or seats available/unavailable frequently. Further,
imagine it's somewhat expensive to build the airplane object graph.
However without constructing the entire graph for each sale attempt I
don't see how you can keep business rules out of the persistence layer,
which in my mind is an absolute must.
Is oop just not a viable choice for this kind of problem?

Can not download sources with Intellij Idea community 12.1.4 and maven 3.0.5
I click "download sources and documentation" in Intellij Idea Community
Edition 12.1.4 and get error that sources can not be downloaded. But when
I try:
mvn dependency:sources
All sources are downloaded.
What is the problem?
P.S. I have checked that Idea use the same maven that use in console.
There are not any "off line" mode buttons triggered in Idea.

JSF + Primefaces + CRUD: Running a custom query
JSF + Primefaces + CRUD: Running a custom query
OOTB I've got two database tables. They have several columns mostly of
varchar types, each have an int id column as the primary key. I'm using
Netbeans and JPA and have a pretty cool PrimeFaces generic app that I've
altered to use the auto generated Entity.java, Controller.java and
Facade.java pages. However, I'm PrimeFaces and JPA... I would like to
write a "new" query and run it. I've spent hours googling and testing
different ways with zero success. I simply want to know the easiest way to
either add a new query to the Entity's NamedQueries list for example:

So how do I get my custom query to populate this data table? Currently,
using the default "items" from TUnitsController WILL populate this table,
but I have found it EXTREMELY frustrating to try and customize anything
with JPA or Jquery. The CRUD auto generated pages are really complicated
and restricting.
OOTB I've got two database tables. They have several columns mostly of
varchar types, each have an int id column as the primary key. I'm using
Netbeans and JPA and have a pretty cool PrimeFaces generic app that I've
altered to use the auto generated Entity.java, Controller.java and
Facade.java pages. However, I'm PrimeFaces and JPA... I would like to
write a "new" query and run it. I've spent hours googling and testing
different ways with zero success. I simply want to know the easiest way to
either add a new query to the Entity's NamedQueries list for example:
Here's the first table called t_units as it's formal name in mysql.
@Named("tUnits")
@Entity
@Table(name = "t_units")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "TUnits.findAll", query = "SELECT t FROM TUnits t"),
@NamedQuery(name = "TUnits.findById", query = "SELECT t FROM TUnits t
WHERE t.id = :id"),
@NamedQuery(name = "TUnits.findByMake", query = "SELECT t FROM TUnits
t WHERE t.make = :make"),
@NamedQuery(name = "TUnits.findByModel", query = "SELECT t FROM TUnits
t WHERE t.model = :model"),
@NamedQuery(name = "TUnits.findByYear", query = "SELECT t FROM TUnits
t WHERE t.year = :year"),
@NamedQuery(name = "TUnits.findByFuelType", query = "SELECT t FROM
TUnits t WHERE t.fuelType = :fuelType"),
@NamedQuery(name = "TUnits.findByOrigPurchaseDate", query = "SELECT t
FROM TUnits t WHERE t.origPurchaseDate = :origPurchaseDate"),
@NamedQuery(name = "TUnits.findByOwner", query = "SELECT t FROM TUnits
t WHERE t.owner = :owner"),
@NamedQuery(name = "TUnits.findByOperator", query = "SELECT t FROM
TUnits t WHERE t.operator = :operator"),
@NamedQuery(name = "TUnits.findByDecommFlag", query = "SELECT t FROM
TUnits t WHERE t.decommFlag = :decommFlag"),
@NamedQuery(name = "TUnits.findByPoNum", query = "SELECT t FROM TUnits
t WHERE t.poNum = :poNum"),
@NamedQuery(name = "TUnits.findByServiceNum", query = "SELECT t FROM
TUnits t WHERE t.serviceNum = :serviceNum"),
@NamedQuery(name = "TUnits.findByOrigPurchasePrice", query = "SELECT t
FROM TUnits t WHERE t.origPurchasePrice = :origPurchasePrice"),
@NamedQuery(name = "TUnits.myNewQuery", query = "select t from TUnits
t where t.decommFlag = 'false'")})

So how do I get my custom query to populate this data table? Currently,
using the default "items" from TUnitsController WILL populate this table,
but I have found it EXTREMELY frustrating to try and customize anything
with JPA or Jquery. The CRUD auto generated pages are really complicated
and restricting.
