Evaluate $ \lim_{x\rightarrow{\frac\pi2 }} (\sec(x) \tan(x))^{\cos(x)}$
without L'Hôpital's rule – math.stackexchange.com
I have tried changing limit to $\lim_{x\rightarrow0}$ and use some
trigonometry identity ($\sin^2(x)+\cos^2(x) = 1$ and $\sin (x+\pi/2) =
\cos(x)$) but doesn't work I have no idea on how to do this …

How to show that $(\delta'f)(e)=\delta(\phi^* f)(e)$?
How to show that $(\delta'f)(e)=\delta(\phi^* f)(e)$?
I am reading linear algebraic groups.
I have a question in line 4 of the third paragraph of Page 66. How to show
that $(\delta'f)(e)=\delta(\phi^* f)(e)$ for all $f\in K[G]$? Here $G$ is
an algebraic group, $K$ is an algebraic closed field, $\delta' =
\operatorname{Ad} x(\delta) = d(\operatorname{Int} x(\delta))$,
$\phi=\operatorname{Int} x$, $\operatorname{Int} x(y) = xyx^{-1}$, $x, y
\in G$. Thank you very much.
I think that $\delta'f = d(\operatorname{Int} x(\delta))f$.

Remove x amount of elements with .remove()
Remove x amount of elements with .remove()
I am not seeing any clear documentation on removing a certain amount of
elements without it being in a specific order, of course there are many
ways to remove a list of say 5 items, if they are in that order. What if
there is elements that you don't want removed in between? Let me show you
an example
FIDDLE: Below is just pieces from this fiddle, it would be easier just
taking a look at the fiddle.
HTML
<div class="item empty">Empty</div>
<div class="item empty">Empty</div>
<div class="item editable">Editable</div>
<div class="item empty">Empty</div>
</div>
<button class="demo">Demo</button>
jQuery
$('.demo').click(function() {
var length = $('.item').length,
columns = 12/6,
addColumn = columns - length
//Set this for subtracting elements if addColumn is a negitive
if(addColumn < 0) {
//Want to remove the amount of items which is -2 in this case
$('.item.empty').eq(/*Remove whatever amount of addColumn */ ).remove()
}
//Equals -2
alert(addColumn)
});
So just to be clear, I am trying to remove the amount of .empty items
based on whatever the amount is passed into the addColumn variable in this
case its static set at -2.
So I ask if addColumn < 0 is a negative number then we do subtraction
using .remove() and I need to remove the amount of .empty items equal to
the addColumn variable.
12/6 comes from a 12 column grid and the 6 is a two column layout span6
span6 and so if the layout is set at 4 columns we need to remove 2
columns, which is where the -2 comes from.

Getting div id by GET in Javascript
Getting div id by GET in Javascript
Ciao
I need to create a dynamic form based on user selections.
I.e. in the first form field I select "John Smith", this will populate
(through an external php/mysql file ) the second select field "Artist,
Carpenter, Other", if I choose Artist I populate the third select field
with "Singer, Painter, Sculptor" and so on
Giving my incompetence on javascript, I spent the morning googling for
scripts and I found a cool tutorial here
It works, it's clean, but it updates only the div with id txtResult, which
is statically included in the js file (see lines 19 and 31 of
ajax_req.js). I thought I could pass the id name by GET, but I don't know
how to make the script recognize the variable.
This is the code:
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtResult").innerHTML=
xmlHttp.responseText;
}
}
I had in mind to pass by GET the id name and have something like this:
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("GET[idName]").innerHTML=
xmlHttp.responseText;
}
}
Can you please help me? I could change script too if you happen to know
something better
Ciao and thank you,
Ed

SQL- Getting maximum value along with all other columns?
I have a table, which can be seen as a evaluation of two courses in
several classroom tests, like this:
student_ID Evaluation Course1 Course2
------------------------------------------------------
1 5 88 93
2 4 70 87
1 5 93 90
2 5 99 91
3 3 65 60
3 4 88 70
I need to get the result of the Evaluation=5 for each student, if any. If
that student has more than one Evaluation=5, the query only show any one
of them. So for the above example table, the query result will be
student_ID Evaluation Course1 Course2
------------------------------------------------------
1 5 88 93
2 5 99 91
Of course in my real table, the "Courses" number is more than 2.
Thanks for the help.

How to create FlexSlider with flipping content
How to create FlexSlider with flipping content
I'm starting to get in to web development. I'm keenly interested on
minimal designs and flat UIs.
I was googling around and found some interested sites. This particular
site caught my eye which has a unique slideshow. I did a bit of snooping
with dev tools and found that the site uses Flexslider.
I would really like to know how to achieve this kind of effect.
A sample on Fiddle with 2 image slides with flipping content would be
really appreciated if possible to be provided.

How to increment a single number in a text file with PHP
How to increment a single number in a text file with PHP
I am writing a VoteBox (like/dislike box) in html and I cannot find how to
do this anywhere.
Basically, there will be a like and a dislike button. When one of them
gets clicked, it will forward the user to a page. And in that, I want some
PHP code that will increase the number in upvotes.txt/downvotes.txt
I have tried doing it with a database but the problem is I want anyone to
be able to use this without any setup.
i also want the front page to display the number of upvotes and the number
of downvotes
so its kinda like this (most of this isn't real code BTW im new to PHP):
//this is the code for upvote.html
$upvotes = get_data_from_TXT_file
$changedupvotes = $upvotes + 1
set_data_in_txt_file_to_$changedupvotes
Sorry if i havent explained this very well

Pretty new to Java, how to insert user-inputted string to direct a reference?
Pretty new to Java, how to insert user-inputted string to direct a reference?
(In java,) This may or may not be possible, I assume it is because it
seems to short-cutty/easy to not exist. Basically what I want to do is
have the user insert the name of a state, then it add one to that state's
counter, which is stored in a different class. I want to do this without
creating 50 if/else statements. Here's pseudocode which represents how I
would expect it to be done. (this code would be encapsuled in a while loop
in mainclass.java and the counters and state names are in a class named
state.java.)
Scanner userstate = new Scanner(System.in);
String statename = userstate.nextLine();
state.(statename).counter++;
in state.java:
public state(int counter){
}
public static state Alabama = new state(0);
For time's sake, I hope there is a shortcut similar to the above.

Facebook API: best way to get like, share, comment count for a page/group post?
Facebook API: best way to get like, share, comment count for a page/group
post?
What's the best way to get the like, share, comment count for a post?
I'm trying via FQL but it doesn't seem to give any data when the URL is a
FB post URL:
SELECT like_count, comment_count, share_count FROM link_stat WHERE
url="https://www.facebook.com/Macklemore/posts/10153256675935268"
When I get the post info via the Graph API Explorer:
386050065267_10153256675935268
It gives me the like count and share count and I can get the comment count

Weird thing is when I run that query in my app I don't get the share count
or like count. Am I doing something wrong? Is the data in the explorer
different from what apps have access to?
I know I can get the like count via
386050065267_10153256675935268/likes?summary=true
Biggest thing would be the missing share count.
So summary,
Can you get these stats via FQL? If not, how can you obtain the share
count via the graph API?
Thx.

Javascript string concatenation with a function behaves strange
Javascript string concatenation with a function behaves strange
I am trying to concate something like "string"+function(){return "string"}
in document.write() in javascript.
For example:
document.write("I don't know "+function(){if(true){return "why does it
concat?"}});
And it prints something like this bellow (see it running in the jsfiddle:
http://jsfiddle.net/sadaf2605/3AuLD/):
I don't know function (){if(true){return "why does it concat?"}}
I know I have written something very very silly but still why should it
print something like this? I am curious about that!

Skip before_filter defined with block
Skip before_filter defined with block
Is it possible to skip a before filter in using skip_before_filter when
the before_filter is defined with a block. For example:
class ApplicationController < ActionController::Base
before_filter do |controller|
# filter stuff
end
end
I know, that is it possible using the "normal" way of defining the filter
with a method name.

I have a _categorySelector (ListPicker) populated using :
_categorySelector.ItemsSource = App.ViewModel.Items.Select(m =>
m.Category).Distinct().ToList();
On the SelectionChanged event handler, I want to filter to
MainLongListSelector with the selected value of the ListPicker.
I have this so far, that doesn't work:
private void _categorySelector_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
var query = (from jj in App.ViewModel.Items
where (_categorySelector.SelectedItem as
Parameter).Category == jj.Category
select jj).ToList(); //doesn't work
var qq = App.ViewModel.Items.Select(mm => mm.Category).Distinct();
//doesn't connect selected item content to query
MainLongListSelector.ItemsSource = query;
}
I have List< Parameter > = App.ViewModel.Items where Parameter has a
string Category. In the List, there are 30 Parameters with 4 distinct
Category (Head, Neck, Ears and Throat). The list populates the

sending mass email using java mail API
sending mass email using java mail API
I have a requirement of sending emails to approximately 15,000 email
addresses. Content of the email is same for all. I talked to my mail
server administrator and according to him I can send only 500 emails/
hour. I wrote an utility using java mail API to achieve this. I am
creating a connection(transport.connect()) and then reusing it. My utility
will be running for approx 30 hours to send all 15,000 emails. The
question I have "Is there any limit on number of emails being sent per
connection? And is there any time out issues I could run into? Should I
close the connection and get a new connection at some interval? like after
sending 100 emails or after 1 hour?"

Tomcat possible memory leak
Tomcat possible memory leak
The university I work at uses a Tomcat/Railo server to render ColdFusion
pages. For about 6 months (before I was hired) the servers have been
randomly crashing at different times, usually runnign service railo_ctl
restart has fixed hte issue, however lately this hasn't been working as
well.
Over the past two weeks I've narrowed the issue down, and I'm fairly sure
Tomcat where the issue is coming from. I've never used Tomcat, so I'm not
sure where to start. I have reviewed the Catalina.out files, and looked at
the time when the servers crashed and found this error message:

The university I work at uses a Tomcat/Railo server to render ColdFusion
pages. For about 6 months (before I was hired) the servers have been
randomly crashing at different times, usually runnign service railo_ctl
restart has fixed hte issue, however lately this hasn't been working as
well.
Over the past two weeks I've narrowed the issue down, and I'm fairly sure
Tomcat where the issue is coming from. I've never used Tomcat, so I'm not
sure where to start. I have reviewed the Catalina.out files, and looked at
the time when the servers crashed and found this error message:

Program prints an extra row with value 10 after each input
Program prints an extra row with value 10 after each input
I've got this simple program:
#include <stdio.h>
int main()
{
int c;
while ( ( c = getchar()) != EOF)
printf("%d %c\n", c, c);
return 1;
}
However for some reason when executing i get an extra value ten at the end:
a
97 a
10
b
98 b
10
abc
97 a
98 b
99 c
10
What is the value 10 and where does it come from? How do I stop it from
occurring?

Tomcat Server permission issue
Tomcat Server permission issue
I'm trying to deploy a simple Spring MVC app on a tomcat-hosting site. The
problem is that when I try to start the application I get the following

I know it's due to the policy restrictions imposed by the hosting service,
but I don't know how to solve this, how to modify the application (it's a
sample Spring MVC app you can download here) to work correctly.
Here are the permissions granted by the hosting file. Tomcat version is 6.
grant codebase "file:/home/hostingjava.it/" {
permission java.util.PropertyPermission "*", "read";
permission java.lang.RuntimePermission "getAttribute";
permission java.io.FilePermission "/home/hostingjava.it//-",
"read,write,delete";
permission java.lang.RuntimePermission
"accessClassInPackage.org.apache.tomcat.util.*";
}
Any idea?

I know it's due to the policy restrictions imposed by the hosting service,
but I don't know how to solve this, how to modify the application (it's a
sample Spring MVC app you can download here) to work correctly.
Here are the permissions granted by the hosting file. Tomcat version is 6.
grant codebase "file:/home/hostingjava.it/" {
permission java.util.PropertyPermission "*", "read";
permission java.lang.RuntimePermission "getAttribute";
permission java.io.FilePermission "/home/hostingjava.it//-",
"read,write,delete";
permission java.lang.RuntimePermission
"accessClassInPackage.org.apache.tomcat.util.*";
}
Any idea?

Moving Around A Canvas Without Using Scrollbars
Moving Around A Canvas Without Using Scrollbars
Background:
I have a program using Tkinter as the basis of the GUI. The program has a
canvas which is populated with a large number of objects. Currently, in
order to move all objects on the screen I am simply binding a movement
function to the tag 'all' which of course moves all objects on the screen.
However, it is vital for me to keep track of all canvas object positions-
i.e. after every move I log the new position, which seems unnecessarily
complicated.
Question:
What is the best way to effectively scroll/drag around the whole canvas
(several times the size of the screen) using only the mouse (not using
scrollbars)?
My Attempts:
Apologies if this is a trivial question, I have implemented scrollbars and
found several guides to setting up scrollbars, but none that deal with
this particular requirement.
Thank you for any help!
Example of disused scrollbar method:
from Tkinter import *
class Canvas_On:
def __init__(self, master):
self.master=master
self.master.title( "Example")
self.c=Canvas(self.master, width=find_res_width-20,

verticalbar=Scrollbar(self.master,orient=VERTICAL)
verticalbar.pack(side=RIGHT,fill=Y)
verticalbar.config(command=self.c.yview)
self.c.config(xscrollcommand=horizontalbar.set,
yscrollcommand=verticalbar.set)

Can I use AngularJS 'ng-view' in TideSDK 1.3.1beta?
Can I use AngularJS 'ng-view' in TideSDK 1.3.1beta?
I've got a simple TideSDK application going, using AngularJS. Works nicely.
Recently as I started adding features, I replaced my single ng-include
with ng-view and Angular routing. It works great in Chrome, but errors
galore in TideSDK.
Is it possible to use ng-view in an application built with TideSDK 1.3.1beta?

Attach CSV created with fputcsv to email
Attach CSV created with fputcsv to email
I have a function that compiles a custom CSV file using fputcsv. I also
have it email to an address submitted through a prior form via POST. I'm
sending headers so that way when the function is called, it just downloads
the CSV, but I'm unsure how to have it email AND attach the CSV, then
download the CSV.
Here is the entire function -
//SEND EMAIL
$emailTo = $_POST['$submitemail'];
$mailHeader = "From: **********r\n";
$mailHeader .= "Reply-To: ***********\r\n";
$mailHeader .= "MIME-Version: 1.0" . "\r\n";
$mailHeader .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$message = "Here is an email.... attach CSV too!";
$subject = "Email with text and CSV";
mail($emailTo, $subject, $message, $mailHeader);
//GATHER DATA
$user_ID = $id;
$query = "SELECT * FROM hours WHERE user_ID = '$user_ID' ORDER BY date ASC";
$query2 = "SELECT * FROM users WHERE ID = '$user_ID'";
$result = $db->query($query);
$result2 = $db->query($query2);
$row2 = $result2->fetch_object();
$full_name = $row2->full_name;
$organization = $row2->organization;
$importantstuff = array('Hours for - ' . $full_name, 'Site - ' .
$organization);
if (!$result) die('Couldn\'t fetch records');
$headers = $result->fetch_fields();
foreach($headers as $header) {
$head[] = ucfirst($header->name);
}
//START GENERATING CSV
$fp = fopen('php://output', 'w');
if ($fp && $result) {
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="report-'.
$full_name .'.csv"');
header('Pragma: no-cache');
header('Expires: 0');
fputcsv($fp, array_values($importantstuff));
fputcsv($fp, array_values($head));
while ($row = $result->fetch_array(MYSQLI_NUM)) {
$row[1] = $full_name;
fputcsv($fp, array_values($row));
}
die;
}
So, this is where I get a little lost because I am sending the headers
before I actually have the entire CSV created, hence I can't attach them
to an email before everything is done. I'm not sure how I would accomplish
both in the same function. Can I?

How to do wildcard bean mapping in Spring MVC?
How to do wildcard bean mapping in Spring MVC?
I'm trying to do RESTful URL mapping in Spring 2.5. This essentially
means: /fetch/(something) should all be matched to controller fetch
And the controller will do something according the parameter (something)
I add this to my spring config:
<bean id="fetchController" class="(package).fetchController"
scope="singleton"/>
<bean id="fetchService"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/fetch/*">fetchController</prop>
</props>
</property>
</bean>
and add the following to my web.xml
<servlet-mapping>
<servlet-name>springGlobal</servlet-name>
<url-pattern>/fetch/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>springGlobal</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>

Angular.js - re-open and add dependencies to an already bootstrapped application
Angular.js - re-open and add dependencies to an already bootstrapped
application
Is there a way to inject a late dependency to an already bootstrapped
angular module? Here's what I mean:
Say that I have a site-wide angular app, defined as:
// in app.js
var App = angular.module("App", []);
App.directive("fancy-table", ...)
And in every page:
<html ng-app="App">
Later on, I'm reopening the app to add logic based on the needs of the
current page:
// in reports.js
var App = angular.module("App")
App.controller("ReportsController", ['$scope', function($scope) {
// .. reports controller code
}])
Now, say that one of those on-demand bits of logic also requires their own
dependencies (like ngTouch, ngAnimate, ngResource, etc). How can I attach
them to the base App? This doesn't seem to work:
// in reports.js
var App = angular.module("App", ['ui.event', 'ngResource']); // <-- raise
error when App was already bootstrapped
I realize I can do everything in advance, i.e -
// in app.js
var App = angular.module("App", ['ui.event', 'ngResource', 'ngAnimate',
...]);
Or define every module on its own and then inject everything into the main
app (see here for more):
// in reports.js
angular.module("Reports", ['ui.event', 'ngResource'])
.controller("ReportsController", ['$scope', function($scope) {
// .. reports controller code
}])
// in home.js
angular.module("Home", ['ngAnimate'])
.controller("HomeController", ['$scope', '$http', function($scope, $http){
// ...
}])
// in app.js, loaded last into the page (different for every page that
varies in dependencies)
var App = angular.module("App", ['Reports', 'Home'])
But this will require I initialize the App everytime with the current
page's dependencies.
I prefer to include the basic app.js in every page and simply introduce
the required extensions to each page (reports.js, home.js, etc), without
having to revise the bootstrapping logic everytime I add or remove
something.
Is there a way to introduce dependencies when the App is already
bootstrapped? What is considered the idiomatic way (or ways) to do this?
I'm leaning towards the latter solution, but wanted to see if the way I
described could also be done. thanks.

Exposing CORBA Services as Web Services with Apache CXF?
With Axis2 you can expose a CORBA Service as Web Service as described in
the docs: http://axis.apache.org/axis2/java/core/docs/corba-deployer.html
Is this possible with CXF, too? There are Corba samples, but as I
understand, they are a Web Service clients that internally go to a Corba
Server, which is never exposed as Web Service, is it?

how to detect if FTP is working or not onremote machine?
how to detect if FTP is working or not onremote machine?
I have 3 machines(A, B & C) connected to a Router. A,B & C are in same
subnet. All these three machines are interconnected using STAF. I am using
machine A as an FTP server & machine B as an FTP client. Using STAF
command from machine C I am starting FTP program (TCL script) on machine
B.
Now the question is, How C will know whether FTP traffic is flowing
between A & B?

using and overloading a template member function of a base class?
using and overloading a template member function of a base class?
In the following, struct Y overloads X's member function f. Both overloads
are template functions, but take different arguments (typename and int),
to be explicitly specified:
struct X
{
template <typename> static bool f() { return true; }
};
struct Y : public X
{
using X::f;
template <int> static bool f() { return false; }
};
int main()
{
std::cout << Y::f <void>() << " " << Y::f <0>() << std::endl;
}
This prints 1 0 using gcc, as expected. However, clang (3.3) complains that
[...] error: no matching function for call to 'f'
std::cout << Y::f <void>() << " " << Y::f <0>() << std::endl;
^~~~~~~~~~~
[...] note: candidate template ignored: invalid explicitly-specified argument
for 1st template parameter
template <int> static bool f() { return false; }
^
i.e., can only see Y's version. I've tried
using X::template f;
instead, with no success. The same happens for non-static (template)
member functions. So is this a bug?

Adding callback to jquery .submit() to read error responses from uploads
Adding callback to jquery .submit() to read error responses from uploads
I've got an iframe #uploadTarget which I'm using for image uploads:
function uploadImage(){
if ($('#imageUploader').val().length > 0){
$('#uploadingIndicator').show();
// set form params such that it uploads image
$('#uploadForm').attr("action", uploadUrl);
$('#uploadForm').attr("enctype", "multipart/form-data");
$('#uploadForm').attr("target", 'uploadTarget');
// submit for image upload
$('#uploadForm').submit();
resetFormAttributes();
//console.log($('#uploadTarget').contents().find('body').text());
} else {
resetFormAttributes();
$('#uploadForm').submit();
}
}
When image upload is done, the page inside the iframe executes javascript
which calls doneUploading outside the iframe.
In the event where the file is too big or an error occurred and an error
page is displayed in the iframe, the doneUpload function is not called.
Is it possible to have some sort of a callback function that triggers
after $('#uploadForm').submit() completed (in which case I'll read the
page for error responses)?
If not, how would I read error responses being returned inside the iframe?

With a JS Regex matching exact word but not hypenated words starting with said word
With a JS Regex matching exact word but not hypenated words starting with
said word
I could not find a match to this question.
I have a string like so
var s="one two one-two one-three one one_for"
and my function is as follows
function replaceMatches( str, word )
{
var pattern=new RegExp( '\\b('+word+')\\b','g' )
return str.replace( pattern, '' )
}
the problem is if I run the function like
var problem=replaceMatches( s,'one' )
it
returns two -two -three one_four"
the function replaces every "one" like it should but treats words with a
hyphen as two words replacing the "one" before the hyphen.
My question is not about the function but about the regex. What literal
regex will match only the words "one" in my string and not "one-two" or
"one-\w"<--you know what I mean lol
basically
var pat=/\b(one)\b/g
"one one-two one".replace( pat, '')
only replace the exact match "one" and not the one in "one-two" the "one"
on the end is important to, the regex must work if the match is at the
very end Thank you, sorry if my question is relatively confusing. I am
just trying to get my learn on, and expand my personal library.

Specific PhpStorm and XAMPP configuration?
I want to move from Netbeans 7 to PhpStorm 6 (Windows7 x64) due to some
reasons but cannot arrange in the same 'netbeans' manner my configuration,
in which my source files live outside of htdocs folder of XAMPP and every
time I change sources I expect them to be immdediately uploaded to htdocs
for preview in browser at localhost. Up to this time I have seen only
those PhpStorm+XAMPP configurations, which define source folder inside of
c:\xampp\htdocs, which is not my preferred style, sorry. Articles I have
seen so far:

Prevent double submission of form using jQuery
Prevent double submission of form using jQuery
Problem:
I have a script where the user can press the keys C or M to choose an
option. Once either key is pressed the form will be submitted. Since there
is a strict rule that each option can be submitted once, some press
multiple times.
Question:
How can I prevent users from submitting the form again after they have
pressed the C or M key? I want them to be able to press either key once
the page refresh after submission.
Code in PHP / jQuery:
if (in_array($checkstring, $footer))
{
echo '
<script type="text/javascript">
$(document).ready(function()
{
$(window).keypress(function(e)
{
if (e.which == 99)
{
$("input#left").val( 1 );
$("form").submit();
}
else if (e.which == 109)
{
$("input#right").val( 1 );
$("form").submit();
}
});
'.$warning.'
});
</script>
';
}
