Read text lines using QDataStream or QTextStream or neither from tcpsocket?
I am creating a simple TCP server, and have a slot/function built which
reads incoming text from a client (telnet connection) on a TCP socket.
I've used the Fortune code examples to help me, but had to remove
QDataStream since it didn't work as expected.
I want my readCommand function to collect incoming characters from a
telnet client connection, and once it finds a newline or return to remove
the typed command from the input buffer, remove /n and /r, add it to my
string list (commandList), and then echo the commands (seperate function).
Here's what I've got so far:
void MyServer::readCommand()
{
inBuffer += tcpSocketPtr->readAll();
// While newline is present, extract the command
int nextNewlinePos;
while ((nextNewlinePos = inBuffer.indexOf('\n')) > -1) {
commandList << inBuffer.left(nextNewlinePos);
inBuffer.remove(0,nextNewlinePos);
// Get rid of /n /r if present somehow
}
if (commandList.size() > 0)
{
echoCommand();
}
}
Before I start stripping /n and /r etc. manually, my gut is telling me
there is a better way to do this. Is QTextStream the way to go? Can
someone provide a simple(r) alternative to what I am trying to achieve?

Escape colon in url string
Escape colon in url string
I have a string:
$fonts = "Arial:400";
When I use that in a URL, the colon prints as %3A. How can I escape the
colon so that it prints as :? I have tried preg_replace and url_encode
with no luck. I'm sure its simple but I have searched.

why did Joshua Bloch decrement the "size" value of stack in the pop method in effective java?
why did Joshua Bloch decrement the "size" value of stack in the pop method
in effective java?
here is the code from Item 6, pg 24, chapter 2 of effective java 2nd
edition, by Joshua Bloch. In the pop method he defines, he uses
elements[--size]. I am wondering why he used --size, instead
elements[size--] should return the same correct?
public class Stack {
private Object[] elements;
private int size = 0;
private static final int DEFAULT_INITIAL_CAPACITY = 16;
public Stack() {
elements = new Object[DEFAULT_INITIAL_CAPACITY];
}
public void push(Object e) {
ensureCapacity();
elements[size++] = e;
}
public Object pop() {
if (size == 0)
throw new EmptyStackException();
return elements[--size];
}
/**

* doubling the capacity each time the array needs to grow.
*/
private void ensureCapacity() {
if (elements.length == size)
elements = Arrays.copyOf(elements, 2 * size + 1);

External PHP file returning error with the result?
I have an external PHP file which updates mysql database (this file is

require( $file . "/wp-load.php");
if (something){echo ($var);}

How to stop timer on killing app android
How to stop timer on killing app android
How do I stop my timer when I close my App (Using the Return/exit
button((Not home button)))?
When I close my App using the back button it's not in the task messenger,
but the timer (Sending notifications on events) is still running and
sending me notifications..
I thought as it is not in the tasks, and I use the return button to close
the timer would also stop.. When I open the app again after closing it it
does restart on it's mainactivity unlike opening it when I used the "home"
button..

After editing a destination path, editing motion tween no longer affects whole curve
After editing a destination path, editing motion tween no longer affects
whole curve
I created a motion tween, and at the final frame moved the symbol to its
destination. I was then able to manipulate the curve by dragging the
points, or using the subselection tool to invoke the bezier handles, and
everything looks smooth. However, if I then move the object, even a tiny
bit, future changes to the curve now no longer smoothly affect the whole
curve, but will bend and contort it in tiny subsections, resulting in a
very knotted curve, and the only way to get back there is to undo my way
up the stack to where I dragged the object in the destination frame and
redo my desired curve.
Clicking on the object and moving it is doing something to my editing
mode, but for the life of me I cannot see what it is. Might anyone be able
to tell me what it is, and what I would have to do (I am using Mac OS X
CS6) to return myself to being able to smoothly tweak the whole curve and
not just subsections?

Find the first non repetitive character in a string
Find the first non repetitive character in a string
I was asked this question in an interview. My answer: "create an array of
size 26. Traverse the string by each character and make counts of
characters in the array. Check the first non repetitive character by
traversing again in the string and checking the array if the character is
not repeated." What if the string contains large set of characters like
10000 types of characters instead of 26 types of alphabets.

Why does the while True loop apply to count in this circumstance? I dont

why notation pat ... means zero or more expressions in scheme macro pattern
why notation pat ... means zero or more expressions in scheme macro pattern
When I'm reading the macro part of The Scheme Programming Language, it
mentions that when you are trying to define a syntax extension using
define-syntax, you should use pat ... to specify zero or more expression
in the pattern. Why don't just use ... for zero or more expression, in
which case pat ... means one or more expressions?
Also, when the author gives definition of and as follows:
(define-syntax and
(syntax-rules ()
[(_) #t]
[(_ e) e]
[(_ e1 e2 e3 ...)
(if e1 (and e2 e3 ...) #f)]))
Why don't just write it like this:
(define-syntax and
(syntax-rules ()
[(_) #t]
[(_ e) e]
[(_ e1 e2 ...)
(if e1 (and e2 ...) #f)]))
I have tested this definition with some cases, and I didn't find any
problem with it.

If you have a page that is remaining inactive for a long time and because

every 8 minute. Meanwhile the server crashes let's for 20 minutes. The
question is what type of refresh I have to do into the page so that after
an hour if I come back and want to navigate to the page. I assume that
server is live again. Is there any type of refresh do that?

Need help setting up a logic behind a Facebook notification system style
Need help setting up a logic behind a Facebook notification system style
I want build a notification system to my website, similar to Facebook. The
notifications don't need to be in real time.
This is what I have in mind:
User create an event (upload a new photo, add a new comment, like a photo,
or even an administration alert to all users)
Run a cronjob every 5 minutes to add the notifications into the
notifications table:
id|id_content|type_of_content_enum|affected_user_id|date|seen_bool
The cronjob, will run several functions for each type of notification, for
example:
add_photos_notification() // This function will check all photos added in
the past 5 minutes, and insert a row in the notification table, for each
user following this person. The function will group all photos added into
the past 5 minutes, so the follower don't get many notifications for the
same type of content. Resulting in a notification like: User X added Y
photos in his profile.
add_admin_notification() // This function will check all news added by the
administration of the site in the past 5 minutes, and insert a row in the
notification table, for each user on the system ...
Is this a correct approach to build a notification system?
Is it possible to miss an event, running a cron every 5 minutes where
functions retrieve the past 5 minutes events?
To be safe, do you think an alternative could be checking all events where
a field 'notified' is not true? The same function that will grab the
events where 'notified' = false, update it to true after adding that
notification into the notifications table.
Thanks,

Android - Getting activity object from startActivity
Android - Getting activity object from startActivity
Folks,
I need to get the instance of the Activity that was created when
startActivity() is called. However, startActivity() returns a void value.
I guess startActivity() doesn't wait until the Activity is created.
Is there a different way for me to get hold of the activity that was just
created on the call to startActivity? Or, perhaps I can create an Activity
instance myself and register it somewhere so that startActivity can find
it.
Thank you in advance for your help.

Peter

Rails validate model with attribute
Rails validate model with attribute
I need to do a custom validation that checks if the attribute being
updated is less than another attribute on that record. I tried doing this:
validates :team_size, :numericality => { :greater_than_or_equal_to =>
self.users.count }
But it comes back with the error:
NoMethodError (undefined method `users' for #<Class:0x007fcda9a548e8>):
I also tried doing a before_save hook with a method like this:
def validate_team_size
if self.team_size < self.users.count
errors[:base] << "Custom message."
end
end
But it just ignores it - I'm assuming because the team_size attribute
hasn't been updated yet so I'm checking the old value. Also tried using
after_save which is just before it commits but no luck either.

Angular $event undefined in Firefox
Angular $event undefined in Firefox
As said in the angular api docs, ng-mouseenter makes event object
available as $event.
HTML:
<div ng-mouseenter="enter('test', $event)">Enter mouse over here</div>
JS:
$scope.enter = function(data, $event) {
console.log($event.x);
};
Use this fiddle and notice that...
in chrome the log gives: 77 (or another number)
And firefox gives the log: undefined.
Am I using $event the wrong way or does $event not work in Firefox?

What is the use of structure having only one element?
What is the use of structure having only one element?
Example:
struct dummy
{
int var;
};
Why structures like this are used? Mostly I have seen them in some header
files.
The atomic_t type is also defined like this. Can't it be defined simply
using:
typedef int atomic_t;
Example:
struct dummy
{
int var;
};

Why are my instance variables not existing across methods of the same class in ruby?
Why are my instance variables not existing across methods of the same
class in ruby?
I am doing the ruby koans and I am on the DiceSet project. I've made the
DiceSet class but my instance variables don't seem to persist with the
instance like I thought they would. My code is
class DiceSet
attr_reader :values
@values = []
puts @values.class
def roll(number_of_rolls)
(1..number_of_rolls).each do |roll|
puts @values.class
@values << (1..6).to_a.sample
end
return @values
end
end
The koan then uses my DiceSet class with
dice = DiceSet.new
dice.roll(5)
puts dice.values.class
assert dice.values.is?(Array)
I put the puts commands in there to follow whats happening with the
@values instance variable and only the first puts @values.class says its
an Array class. All the others are returning NilClass. Am I using instance
variables incorrectly or is there something else I am missing? Do instance
variables get deallocated after a method call?

Specify locale in string resource identifier
Specify locale in string resource identifier
Is it possible to reference a string resource by locale, in XML?
For example, what if I want to read the French version of a string
resource no matter what locale I'm currently in. This can be done in Java
but can it be done in XML?
In other words, is there anything like this? @string-fr/my_string

Attribute duplication importing HoloEverywhere and ActionbarSherlock in Eclipse
Attribute duplication importing HoloEverywhere and ActionbarSherlock in
Eclipse
I have been struggling with this problem for hours now. I have tried all
tips I found at StackOverflow, but they did not help me.
The problem:
I have imported HoloEverywhere in Eclipse. I then imported
ActionbarSherlock into HoloEverywhere, as is said here only to get a bunch
of errors. Also, R.java is not being generated for the HoloEverywhere
project (I tried cleaning all projects, didn't work).
Judging by the log output, I'd say there are repeating attribute names in
the ActionbarSherlock and HoloEverywhere projects. How do I fix that?
Here is part of the log:

How can I combine these jQuery .on() functions?
How can I combine these jQuery .on() functions?
Here is my code. The swipes are for anywhere in the document, the click is
for the close img, but they execute the same code. Any advice? It's not an
overly big deal, but I would like smaller, cleaner code if I can. This is
for a modal type window.
$(document).on("click", "#close", function () {
ttl.html(docTitle + air);
window.history.pushState({}, docTitle + air, docURL);
}).on("swipeleft swiperight", function () {

EAR generated using ANT doesn't work on Websphere 8.5
EAR generated using ANT doesn't work on Websphere 8.5
The object is to build .ear by using ANT then deploy it on Websphere 8.5
with wsadmin.
Manually, the ear file is generated from a jar file and after deployment,
the web application works very well.
But if I use the ear generated by ANT, after deployment (by hand or by
wsadmin), I always have this error :
SRVE0255E: A WebGroup/Virtual Host to handle /WebApp$%7Blogout.url%7D has
not been defined.
SRVE0255E: A WebGroup/Virtual Host to handle localhost:9080 has not been
defined.
Someone knows which might invoke this problem. I met this message before
while my colleague deploy on websphere with a war file directly from a
Tomcat server.
Thanks in advance.

How do I plot a number of categorical variables on a graph in R?
How do I plot a number of categorical variables on a graph in R?
I have about 10 categorical variables - pay1, pay2, ... , pay10 each
having values either 'Yes' or 'No'. I would like to plot the count of each
of these variables on a graph. For example - bar1 on the chart should
refer to the variable 'pay1' reflecting the total number of observations
divided between 'Yes' and 'No'('Yes' on top of 'No' or vice versa) This
scheme should be consistent with all the 10 variables on the chart. If I
am able to display the percentage of 'Yes' and 'No' for each bar, even
better. Would someone be able to help out on this?
TIA.

This compiles fine.

PHP wildcard redirection script?
PHP wildcard redirection script?
So I just moved my site from /blog to / (root) directory. Now for those
people who know previous /blog URL, I want to redirect them to new URL
(/).
So I have put this index.php file in /blog dir:
<?php
header( 'Location: http://www.abc.com' ) ;
?>
and it works. But I want this: When a user visits any blog post from old
url like http://abc.com/blog/sample-post then instead of redirecting to
abc. com, it should redirect to abc. com/sample-post
I think it may also be done by .htaccess redirection but I dont know
htaccess method.
Please give me code for this :)

Can't install or deploy h2-console for JBoss
Can't install or deploy h2-console for JBoss
I've been working through the instructions here:
http://www.jboss.org/jdf/quickstarts/jboss-as-quickstart/h2-console/#deploy_the_h2_console/
However, I can't figure out what is meant by this line of the
instructions: "Deploy the console by copying the
QUICKSTART_HOME/h2-console/h2console.war to the
$JBOSS_HOME/standalone/deployments directory."
After installing the greeter quickstart, I did not have an "h2console.war"
anywhere. So I downloaded all of the quickstarts from here:
http://www.jboss.org/jdf/quickstarts/jboss-as-quickstart/ after which I
had that file.
I then copied that file to the suggested folder, but that didn't seem to
do anything as the suggested localhost does not load the console.
I've searched high and low but the documentation on h2-console
installation seems sketchy at best. What am I missing?

How to filter which attributes I want to delete in Python class?
How to filter which attributes I want to delete in Python class?
There are certain attributes from the class I allow to be deleted. But,
others are forbidden to be deleted.
class klass:
a = 1
b = 2
def __delattr__(cls, attr):
if attr=='a':
pass # go ahead, delete attribute a
elif attr=='b':
raise TypeError("Bad boy/girl, you shouldn't delete attribute b")
del klass.a
del klass.b
This code does not work. What's wrong with the code? Both attributes are
still being deleted. I am using Python 3 by the way. __delattr__ does not
seem to work. Please note, I don't want to instantiate the class (I don't
want foo = klass(); del foo.a; / I want del klass.a;). Thanks.

Hartl's RoR Chapter 8.2.5 - UsersController sign_in undefined
I'm going through Hartl's RoR Tutorial, Chapter 8.2.5
(http://ruby.railstutorial.org/chapters/sign-in-sign-out#sec-signin_upon_signup)
and I couldn't get the "User Pages signup with valid information should
create a user" test to past, with the following messages:
1) User Pages signup with valid information should create a user
Failure/Error: expect {click_button submit}.to change(User, :count).by(1)
NoMethodError:
undefined method `sign_in' for #<UsersController:0x007fcdb3b066d8>
I was able to solve this by using
include SessionsHelper
in the users_controller.rb. I want to make sure that this was what was
implied, and that I am not doing something wrong as I couldn't find the
instructions for including SessionsHelper in the text.

Safari/touchscreen issue with jQuery custom sliding function
Safari/touchscreen issue with jQuery custom sliding function
I am using a premade short jQuery code for a slider to use a special
offer. Here is the jQuery code for the slider:
$(function() {
$(".slider").draggable({
axis: 'x',
containment: 'parent',
drag: function(event, ui) {
if (ui.position.left > 170) {
$well = $(this).closest('.well'); //Select only the
respective well element.
$well.fadeOut(500, function(){
$well.delay(1000).addClass( "disappear" );
$well.prev(".showup").delay(500).removeClass( "disappear" );
});
} else {
// Apparently Safari isn't allowing partial opacity on text
with background clip? Not sure.
// $("h2 span").css("opacity", 100 - (ui.position.left / 5))
}
},
stop: function(event, ui) {
if (ui.position.left < 171) {
$(this).animate({
left: 0
})
}
}
});
$('.slider')[0].addEventListener('touchmove', function(event) {
event.preventDefault();
var el = event.target;
var touch = event.touches[0];
curX = touch.pageX - this.offsetLeft - 40;
if(curX <= 0) return;
if(curX > 200){
$well = $(this).closest('.well'); //Select only the respective
well element.
$well.fadeOut();
$well.addClass( "disappear" );
$well.add('<h2>Erbjudandet använt</h2>');
}
el.style.webkitTransform = 'translateX(' + curX + 'px)';
}, false);
$('.slider')[0].addEventListener('touchend', function(event) {
this.style.webkitTransition = '-webkit-transform 0.3s ease-in';
this.addEventListener( 'webkitTransitionEnd', function( event ) {
this.style.webkitTransition = 'none'; }, false );
this.style.webkitTransform = 'translateX(0px)';
}, false);
});
The HTML for displaying the slider is as such:
return "<link rel='stylesheet'
href='http://www.infid.se/wp-content/themes/simplemarket/anvandstyle.css'>
<script
src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js'></script>

<div class='showup disappear'><h2>Erbjudande använt</h2></div>
<div class='well'>
<h2><strong class='slider'></strong> <span>Använd

</div>
</div>";
And here is the relevant CSS:
.disappear:before {content: "<h2 style='color:#101010;'>Erbjudande
använt</h2>";}
.disappear{display:none;}
The problem with this code is when I add multiple instances of the slider.
It works fine on my computer (1440px width), but when I use it on my
iPhone I can only select one. Just any point in the right direction would
be good, for example if the problem is with the slider or the device. A
working instance can be found here: http://infid.se/mandag/.

HTML, CSS, Jquery help needed
HTML, CSS, Jquery help needed
Hey in my last topic I made a mistake by not putting the css and Jquery in
it. So i've tyed a little more and build a menu in CodePen.
Now the problem i've is that still it doesnt work. I searched but coudn't
find it so thats why i put it here.
http://codepen.io/anon/pen/djwih
HTML is good, css probely not and i'm almost sure that the jquery is good.
Can someone check this for me and correct my mistakes?
On the top i've a logo on the left side and menu has to be on the right
side. The menu has in the correct html an width of 1200px and is margin:0
auto;. But the logo is on the same height as the menu so that's why i've
put #menu ul float:right;.
Thanks in advance for your help!!

AngularJS application hosted on Github pages (gh-pages) ajax crawling
AngularJS application hosted on Github pages (gh-pages) ajax crawling
anyone knows if is possible to make an AngularJS with client-side
navigation crawlable by search engines if it is hosted on Github?
Let's say, my application has 3 client-side urls:
http : //my-example-application.com/#!/home
http : //my-example-application.com/#!/documentation
http : //my-example-application.com/#!/download
These URL's will not be seen by the search engines because they are served
on the client side, but according to Google Ajax applications
recommendations to help search engines the dynamic content generated by a
javascript application could be cached previously, so the crawlers would
search for a cached version of the previous pages on these URL's:
http : //my-example-application.com/?_escaped_fragment_=/home
http : //my-example-application.com/?_escaped_fragment_=/documentation
http : //my-example-application.com/?_escaped_fragment_=/download
This could be accomplished via url rewriting on a web server, but do we
have any alternative if we are hosting the dynamic page on Github?

Animation Using To Much Memory iOS7
Animation Using To Much Memory iOS7
I have a series of .png images loaded into an animation, which works fine,
but when I switch to another view, the memory that the animation uses is
not freed up. Which takes up more and more memory every time you return to
that view until eventually the app quits due to too much memory pressure.
Is there anything I can put in view diddisappear or another method to free
this memory from the animation when the view is changed?
Also this only seems to happen in with my 4S running iOs 7. On my 4S with
6.1.2 it runs smoothly.

HTML Symbol Entity - How to Float
HTML Symbol Entity - How to Float
How do you allow for a HTML symbol entity to float fixed to the browser
screen. It is for a Sign-In page and I want to have a down arrow float
next to a sign in link roughly 25px from left and 10 px from top in the
corner of the page. Thank you

ForkJoinPool.getActiveThreadCount() overestimating thread count
ForkJoinPool.getActiveThreadCount() overestimating thread count
Why ForkJoinPool.getActiveThreadCount() can overestimate the number of
threads? While the ForkjoinPool itself doesnt describe the real reason, it
appears that the rest state of the computing thread (while waiting for the
forked one to join) may be causing it. Not sure why this occurs.

How do I print just the even or odd chars in an array?
How do I print just the even or odd chars in an array?
Lets say I have string: 'firetruck'. And I split that string up into the
individual letters and put them into an array called T for example. So now
T[] looks like {f,i,r,e,t,r,u,c,k}. How can I just print the even chars so
my print statement looks like 'frtuk' and the odd looks like 'ierc'. This
is what I got so far:
import java.util.Scanner;
import java.util.Arrays;
public class StringFun {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String even_odd = sc.next();
char[] t = even_odd.toCharArray();
System.out.println(Arrays.toString(t));
//I can't get this next part to work.
for(int i = t[0]; i < t.length; i = i + 2){
System.out.println(Arrays.toString(t[i]));
}
}
}

Operations with cell array
Operations with cell array
I have 1153 cells that have different values. I was wondering how should I
take for instance the log,sum for the cells separately. I was trying
something lile: S=cellfun(@log,price) but is not working.

Logic In Random Generation
Logic In Random Generation
<?php
$gender = array(
'Male'=>30,

At the moment I am trying to generate a random value based on a weighted

chance. I had a feeling that the logic in the code was wrong, so I ran
script a 100 times, and normally you would get 30 Males, however that
wasn't the case. Is there a smarter way to do this?

Creating child records with Ember-Model
Creating child records with Ember-Model
I've been wrestling with what should be a simple task, using Ember-Model +
Ember.js + Ember-Model-Firebase-Adapter to create child records of a
parent record.
Can anyone provide a quick example of creating a Post and creating related
Comment too boot? Currently on mobile so I can't provide the code I've
been toying with, but later I can. I've been receiving a can't call save
on undefined error when attempting
post. get('comments').save();
I've tried defining post by
var post = App.Post.find();
But this is incorrect. I'm overlooking something simple, any insight or
quick examples out there? Would really appreciate some help.
[EDIT]
Thanks for the help so far. Currently getting an error which I'm looking
into:
Uncaught TypeError: Object [object Object] has no method 'create'
Here's my current controller:
App.PostController = Ember.ObjectController.extend({
newMessage: null,
actions: {
saveComment: function() {
var post = App.Post.create();
var comment = post.get('comments').create({message:
this.get('newMessage')});
comments.save();
post.save();
this.set('newMessage', null);
}
}
});
Should I be setting it as an array controller?
Here are my models:
App.Post = Ember.Model.extend({
id: attr(),
name: attr(),
comments: Ember.hasMany("App.Comment", {key: 'comment_ids'})
});
App.Game.url = "/posts";
App.Comment = Ember.Model.extend({
id: attr(),
message: attr(),
post: Ember.belongsTo('App.Post', {key: 'post_id'})
});
App.Comment.url = "/comments";

Is there a method that i can use to simply find a file location? I'm

ios7 view height error
ios7 view height error
Im playing with ios7 now, find that my view bounds became full screen eg.
before 320*460 now 320*480 with 20px status bar over my view, I know ios7
starts to support full screen layout, and has a
self.edgesForExtendedLayout = UIRectEdgeNone;
to set, but, this line seems work only when the navigation bar is shown,
i cant upload screenshots, and in ios6 view seems normal, and 320*460, in
ios7 its 320*480, status bar covers view contents, if I use a navigation
bar and set self.edgesForExtendedLayout = UIRectEdgeNone; view frame
became 320*416, leaves 20 for status bar and 44 for nav bar, but my app is
a custom top bar, not using navigation bar here.
if change the frame of window, window moves down by 20 px, but status bar
seems clipped and a black 320*20 bar is shown,
any method to make both iOS 6 and ios7 happy?

Multiple dates picker that allows for weekday selection
Multiple dates picker that allows for weekday selection
I'd like to have a datepicker widget that allows for:
multiple date selection
weekday selection, i.e. click "monday" in the calendar and have all
mondays highlighted.
unselecting days that have been highlighted by using the weekday selection
I've looked into Keith Wood's jQuery datepicker and into MultiDatesPickr,
but my JavaScript is very weak and I'm not completely sure of what I have
to do next to extend one of these datepickers and implement this kind of
functionality.
One other option would be to have standard checkboxes outside the input
field, each labeled as a day of the week, and clicking them would
highlight the relevant days in the calendar.
Not sure if it's entirely relevant or useful information, but I'm using
Django 1.5 as the backend and trying to use this as a custom Admin Form
widget.

I also can't stop rails server with Ctrl-C. It displays Stoping... but
just stays like that?
After fired up rails s server it looks really correct.

Java Scanner Error : Exception in thread "main" java.util.NoSuchElementException: No line found
Java Scanner Error : Exception in thread "main"
java.util.NoSuchElementException: No line found
I am trying to get user input but I keep getting the error: No Line Found
The line number is referencing "input = fileS.nextLine();" as the source
of the error
System.out.print("Is this table a simple table? Please check document to
confirm, If YES please Enter Y If NO please Enter N \n");
Scanner fileS = new Scanner(System.in);
input = fileS.nextLine();
input = input.trim();
input = input.toLowerCase();
tableCount ++;
fileS.close();
That is my code, I understand that if I used fileS.hasNextLine() it would
avoid this error But this skips the user input all together.
What am I missing here?
The scanner is in a public function
Thanks in advance!

I'm debugging using visual studio 2010. I want to break when a memory

changed in hundreds of places in the code. I want to find the place in the
code when it is actually changed. How can I do it?

I'm trying to get rid of a certificate warning. I have the following code
that executes before anything else, and forces the user to the https
version of the URL:
if((!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] == "") &&
($_SERVER['REMOTE_ADDR'] != '127.0.0.1')){
$redirect = "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
header("Location: $redirect");
exit();
}
This redirects to the correct URL, but it seems to leave an SSL warning in
its wake:
In the console I get this:
(The page at https://mysite.com/special-offer/ displayed insecure content
from http://mysite.com/special-offer/.)
However if I visit the url ($redirect) directly, no SSL warning is given.
All resources are being served over https.

How to determine similarity between source and mutliple strings in python?
How to determine similarity between source and mutliple strings in python?
Assuming I have the following source string:
Humpty dumpty <span id="1">sat</span> on a wall, humpty dumpty had a great
fall. All of <span id="two">the kings</span> horses and all the kings men.
and a few other strings in a list, each string is separated by a new line:
Humpty dumpty sat on a wall, humpty dumpty had a great fall. All of the
kings horses and all the kings men.
Humpty dumpty sat on the wall, all of the kings horses and all the kings men.
There is a humpty dumpty who had sat on the wall, and all of the kings
horses and all the kings men.
Humpty dumpty sat on some wall, humpty dumpty had a great fall. All of the
kings horses and all the kings men couldn't put him together again.
Humpty dumpty this is a completely related sentence.
I want to be able to starting with the target string, find out which of
the "other strings in the list" that most closely match the source string
using python. Is there some best way to come up with some "score" in the
comparison between the source string and target string pairs and based on
some criteria be able to determine which string is most closely matched to
the source string? (In this case, the string most similar should be the
1st string, as it is the source string without any of the "".

AS3 Is there a simple way of creating this array?
AS3 Is there a simple way of creating this array?
I'll have some task for the user to do, so I'll make an Array(false,
false, false, ... number of tasks) and each element will become true when
completed, so I'll know when all will be completed and witch one is still
incomplete. Usually I create an int to count the tasks when created, and
that decrease, but I need to control each item this time (you didn't
complete this one...), not only the global progress.
So, I got only the number of tasks:
var Ctrl:Array = new Array();
for(var i=0; i<numberOfTasks; i++){ Ctrl.push(false); }
If I have a lot of tasks, this way may take a while freezing the
execution. Is there some "automatic" way?

scala pattern matching nested cases
scala pattern matching nested cases
I try to match after some case applied. Kind of nested cases/matches:
val x1 = 1
val str = x1 match { // scala.MatchError: 1 (of class java.lang.Integer)
case x if(x > 1) => "x"+x match {case "x1" => "yes"}
}
println (str)
It fails with scala.MatchError exception.
Is it possible? It seems I've seen something similar.

Is the use of records the solution to all latch problems in VHDL
Is the use of records the solution to all latch problems in VHDL
I was recently told that the solution to all (most) problems with
unintended latches during VHDL synthesis is to put whatever the
problematic signal is in a record.
This seems like it's a little bit too good to be true, but I'm not that
experienced with VHDL so there could be something else that I'm not
considering.
Should I put all my signals in records?

How to add a table using pdfstamper with itextsharp, in c# or even in vb?
I want to use a function to insert a table to a existing pdf like:
Private Shared Function wTable(ByVal cols As Integer) As
iTextSharp.text.Table
Dim table As New iTextSharp.text.Table(cols)
With table
.WidthPercentage = 100
.BorderWidth = 0
.Cellpadding = 1
.Cellspacing = 0
.TableFitsPage = False
.CellsFitPage = True
.AutoFillEmptyCells = True
.Widths = New Single() {20, 80}
End With
Dim font As iTextSharp.text.Font = font8
Dim fontBold As iTextSharp.text.Font = font8Bold
Dim c As Cell = New Cell(New Phrase("Allacci Sparsi", fontBold))
c.SetHorizontalAlignment("center")
table.AddCell(c, 0, 0)
Dim str As String = "Il termine di esecuzione dei lavori è
stabilito all'art. 14 del Foglio Condizioni e di seguito definiti
in Tabella 1. " _
& "All'art. 16 del 'Foglio Condizioni' sono
definiti i riferimenti per l'applicazione
delle penali in caso di ritardo
nell'esecuzione delle opere richieste. " _
& " All'art. 17 del 'Foglio Condizioni'
sono definiti i criteri per l'incentivo
sulla celerità di intervento."
c = New Cell(New Phrase(str, font))
c.SetHorizontalAlignment("left")
table.AddCell(c, 0, 1)
Return table
End Function
then call it using stamper like:
Dim reader As iTextSharp.text.pdf.PdfReader = Nothing
Dim stamper As iTextSharp.text.pdf.PdfStamper = Nothing
Dim cb As iTextSharp.text.pdf.PdfContentByte = Nothing
Dim rect As iTextSharp.text.Rectangle = Nothing
Dim pageCount As Integer = 0
Try
reader = New iTextSharp.text.pdf.PdfReader(sourcePdf)
rect = reader.GetPageSizeWithRotation(1)
stamper = New iTextSharp.text.pdf.PdfStamper(reader, New
System.IO.FileStream(outputPdf, IO.FileMode.Create))
cb = stamper.GetOverContent(1)
Dim ct = New ColumnText(cb)
ct.Alignment = Element.ALIGN_CENTER
ct.SetSimpleColumn(36, 36, PageSize.A4.Width - 36, PageSize.A4.Height
- 300)
ct.AddElement(wTable(2))
ct.Go()
stamper.Close()

How do you create an index on the tables themselves in a database?
How do you create an index on the tables themselves in a database?
I'm using APSW to wrap my SQL code in python, like so:
connection=apsw.Connection("dbfile"); cursor=connection.cursor()
cursor.execute("create table foo(x,y,z)")
cursor.execute("create table bar(a,b,c)")
cursor.execute("create table baz(one,two,three)")
I plan on using a gui framework to display these table names (and
subsequently their columns and rows). I would also like to sort these
table names by different criteria.
Is there a way to create an index on the tables themselves to be used for
sorting--e.g.:
cursor.execute("CREATE INDEX index_name ON foo")
Thanks in advance.

2D array isn't created as expected in C#
2D array isn't created as expected in C#
In a simple C# console application I have the following:
class Program
public static void Main()
{
string s = Console.ReadLine(); //User enters the string: "integer,
space, integer". Eg., "3 3"
string[,] myArray = new string[s[0], s[0]];
..
..
..
}
Upon debugging, the value of myArray will show string[53, 53], but I'm
expecting string[3, 3]. However, if I Console.WriteLine(s[0]), it prints
"3".
I've tried
string[,] myArray = new string[(int)s[0], (int)s[0]];
with the same result.
Where are the 53's coming from?

std::tr1::bind compile error binding to gluDeleteQuadric()
std::tr1::bind compile error binding to gluDeleteQuadric()
I'm using VS2008 with std::tr1 installed. Here's a stripped down program
that's not compiling:
#include <functional>
#include <windows.h>
#include <GL/glu.h>
void takeQuadric(GLUquadric* obj) {}
int main()
{
std::tr1::bind(&takeQuadric,std::tr1::placeholders::_1);
std::tr1::bind(&gluDeleteQuadric,std::tr1::placeholders::_1); // error
C2825: '_Fty': must be a class or namespace when followed by '::'
return 0;
}
The second bind call fails, probably because the function is declared with
APIENTRY:
void APIENTRY gluDeleteQuadric (
GLUquadric *state);
My WinDef.h says that APIENTRY is WINAPI and that WINAPI is __stdcall
#define WINAPI __stdcall
...
#define APIENTRY WINAPI
Anyone know why it fails to bind and if there is a way I can bind directly
to gluDeleteQuadric?

How to group by seconds without the ISODate decimal part in MongoDB
How to group by seconds without the ISODate decimal part in MongoDB
I wanted to query the database in order to find the number of post per
second to feed into a graph to show activity trend. I use
spring-data-mongo but for now, the first step is to do this in the mongo
shell before worrying about how to do from java.
I used the aggregation framework on it as shown below:
db.post.group({
key:{dateCreated: 1},
cond: { dateCreated:
{
"$gt": new ISODate("2013-08-09T05:51:15Z"),
"$lt": new ISODate("2013-08-09T05:51:20Z")
}
},
reduce: function(cur, result){
result.count += 1
},
initial: {count:0}
})
The result is encouraging but is seems because of the decimal part of the
ISODate, the count seems wrong as it does group per seconds with the
decimal making each count 1.
[
{
"dateCreated" : ISODate("2013-08-09T05:51:15.332Z"),
"count" : 1
},
{
"dateCreated" : ISODate("2013-08-09T05:51:15.378Z"),
"count" : 1
},
{
"dateCreated" : ISODate("2013-08-09T05:51:15.377Z"),
"count" : 1
},
// many more here
]
Is there a way to just consider only the seconds part as in result like
below:
[
{
"dateCreated" : ISODate("2013-08-09T05:51:15Z"),
"count" : 5
},
{
"dateCreated" : ISODate("2013-08-09T05:51:16Z"),

How can I find unknown number x between specific numbers?
Given Values
Min number=2
Max Number=50
increment number=7
x=? needs to be find.
If the correct answer is one of below...How can I find the correct number
that guessed. using given values...
(2,9,16,23,30,37,44)
If this question is hard than, answer below question... :) it is same thing
I would just like to know if it is possible to truncate a sequence to
reset back to its original starting number? in Oracle
Query:
select DBMS_METADATA.GET_DDL('SEQUENCE','SEQ') from dual
Result doesnt give me the original start with value, it only gives the
current value
CREATE SEQUENCE "SEQ" MINVALUE 2 MAXVALUE 50 INCREMENT BY 7 START WITH
9 CACHE 20 NOORDER NOCYCLE

Dynamic Routing with two Dashes in path AngularJS
Dynamic Routing with two Dashes in path AngularJS
I have an interesting problem, I have this rule for routing
'/upload_image/:lat-:lng' , where lat and lng are geo-coordinates
when i try to access with a path like this
(/upload_image/42.04648822804604--71.65695190429688" where the first dash
is the separator between lat and lng as defined in the rule above, but
what happens actually when i try to access $routeParams lat =
42.04648822804604- and lng = 71.65695190429688, this is false coordinates,
angularjs took the second dash as separator between two parameters
according to the rule above, any solution to make it pick up the first
dash always? ( i know i can use other separator than dash but interested
to know if there is a solution + dash is nicer although).

fine as of now, (even my Relay class file) but I am trying to make it into
a full fledged proxy. How could I incorporate elements to send data to the
server, and send the response back to the client? Sort of like a

After creating a customer successfully, I can inspect the object with:
Rails.logger.debug("single card object has:

But, a few days ago, the volume of this errors increased greatly, and for
a lot of url's that I don't even have in my website.
I saw the answers here(Django's SuspiciousOperation Invalid HTTP_HOST
header) and I understand why I'm getting this, but I need to know how to
avoid this increasing my server security.
I'm using Django 1.5, Apache, mod_wsgi and python 2.7, debian hosted on
linode.
Since I upgraded from django 1.3 to django 1.5, I started receive some
error messages, for example: "ERROR (EXTERNAL IP): Internal Server Error:
/feed/". With this traceback:

Django passing view url variables inside a template
Django passing view url variables inside a template
I feel like this is going to be an embarrassing question but I can't find
the answer I've tried google but I am getting fairly frustrated so I just
decided to ask here. I've got this code snippet inside a template file in
django
{% url cal.views.month year month "next" %}
I run the code and get this error Reverse for 'courseCalendar.views.month'
with arguments '(2013, 9, u'next')' not found
Why is it that when I try to pass variables in a string it puts the u in
there as well. This is very frustrating and I would really appreciate
someones two cents.
Edit: Everything works fine if I don't include the string "next" and use a
variable instead like the year and month variables so it's not a url
problem or template problem.
