Click on NSBezierPath
I'm drawing a NSBezierPath line on my NSImageView. I'm creating
NSBezierPath object, setting moveToPoint, setting lineToPoint, setting
setLineWidth: and after that in drawRect of my NSImageView subclass I'm
calling [myNSBezierPath stroke]. It all works just like I want, but I
can't seem to use containsPoint: method... I tried implementing
if([myNSBezierPath containsPoint:[theEvent locationInWindow]]{
//do something
}
in -(void)mouseUp:(NSEvent*)theEvent of my NSImageView subclass but it's
never reacting and I'm sure I'm hitting that line... Am I doing something
wrong? I just need to detect if NSBezierPath is being clicked.
Cheers.

SQL Error: Every derived table must have its own alias
I know there are many questions that deal with this error but I've done

the zipcodes within a certain radius.

All my columns in the database are varchar. zipcode is the primary and I
would make it INT but it doesn't allow there to be 0's at the beginning of
the zipcodes. So I changed it to varchar and it allowed it. Thanks for the

passing bool array to a function
passing bool array to a function
I am passing a bool array to function and doing some modifications in the
passed array inside the function, the changes that I do in the function
are reflected in the original array that I passed to the function.For
example ,in the code below the output is 1 .Why am I getting this output ?
When we pass an integer variable for example ,the local variable maintains
its local value .How can I retain local copy of the original bool array
locally in the code below.
#include<iostream>
using namespace std;
void fun(bool A[30])
{
A[0]=true;
}
int main()
{
bool used[3];
used[0]=used[1]=used[2]=0;
fun(used);
cout<<used[0];

c# asynchronous server with beginReceive
c# asynchronous server with beginReceive
Hi stack overflow members. I'm struggling with some simple code but I
can't get it done. I have this asynchronous server which waits for
connections.
while (clientSocket.Connected)
{
try
{
clientSocket.BeginReceive(so.buffer, 0, 200, SocketFlags.None
, new AsyncCallback(wait),so);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
where so(shorted StateObject) it's my class:
internal class StateObject
{
public TcpClient client;
public byte[] buffer;
public StateObject()
{
buffer = new byte[200];
client = new TcpClient();
}
}
I use this class to put out the information on the callback function.
However I get the system lacked sufficient buffer space or because a queue
was full. I posted a short piece from the actual program. One interesting
issue, is that if I write:
while (clientSocket.Connected)
{
try
{
byte[] buffer = new byte[200];
clientSocket.BeginReceive(buffer, 0, 200, SocketFlags.None
, new AsyncCallback(wait),so);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
it will work, but I will not be able to pull out the buffer from the
asynchronous function(wait). I'm struggling with this and I can't find
answers.

Cognos Reports - No Prompt Page
Cognos Reports - No Prompt Page
I am new to Cognos reports, so bear with me.
I have a report that has two parameters (call them x and y). I have a
prompt page for x and y. The user can supply those values and click finish
to be taken to the report. I am looking for a way to only show that prompt
page if those parameters are not passed in the url string. If those
parameters are set, I want to go directly to the report. I have tried some
js to automatically act as though the finish button has been called, but I
am just getting cognos errors. Any suggestions as to how I can accomplish
this? The prompt page is having the prompt controls set to the values for
x and y in the url.
js -
<script type="text/javascript">
promptAction('finish');
</script>
cognos error -

SQL Using Case in Where clause for null values
SQL Using Case in Where clause for null values
I have a SQL query that I am trying to incorporate the possibility of null
responses in my selections.
Ultimately, this will end up in a SSRS report.
This query works fine, but any null values in p.ReferralReason will always
be returned. I would like the nulls to not be returned if the value of
@Reason is anything but '%':

I would like to incorporate all reasons with the @Reason = '%' If @Reason
is set to '%', I would like to include the null values, but I do not want
to include the null values if @Reason is set to anything else.
This is what I have tried, but it does not work:

Inherit from Python's and override __str__
Inherit from Python's and override __str__
I am interested in doing something similar to what Django is doing to
lists, e.g:
In django shell
In [4]: from TimePortal.models import Rules
In [5]: Rules.objects.all()
Out[5]: [<Rules: day_limit>]
I tried doing the following:
class TimeEntryList(list):
def __str__(self):
return ';'.join([str(i) for
i in self.__getslice__(0, self.__len__())])
Which seems to work in a normal Python shell:
In [54]: a=TimeEntryList(('1-2','2-3'))
In [58]: print a
1-2;2-3
In [59]: str(a)
Out[59]: '1-2;2-3'
However in my application a TimeEntryList instance is really a list of
TimeEntry objects defined like this:
class TimeEntry(object):
def __init__(self, start, end):
self.start = start
self.end = end
#self.duration = (self.end - self.start).seconds / 3600.0
@property
def duration(self):
return (self.end - self.start).seconds / 3600.0
@duration.setter
def duration(self, value):
self._duration = value
def __str__(self):
return '{} - {} '.format(dt.strftime(self.start, '%H:%M'),
dt.strftime(self.end, '%H:%M'),)
When I am printing a single entry everything is ok:
>>> print checker.entries[0]
08:30 - 11:00
When I try slicing, results are different:
>>>print self.entries[0:2]
[<TimePortal.semantikCheckers.TimeEntry object at 0x93c7a6c>,
<TimePortal.semantikCheckers.TimeEntry object at 0x93d2a4c>]
my question is:
How do I inherit from list, and define __str__ so that print only slices
works the following is output when issuing print self.entries[0:2]:
['08:30 - 11:00 ', '11:00 - 12:30 ']
I know this gives the desired out:
[str(i) for i in self.entries[:2]]
However my purpose here is learning a new technique and not necessarily
working with what I already know.

After I upgraded my application to bootstrap 3.0.0 from bootstrap 2.3.2 it
doesn't layout very well, and it seems to be because of missing

NSURLConnection send data twice on server
NSURLConnection send data twice on server
I am creating an iPhone app where i need to send data to server. Using
NSURLConnection I'm able to send data but my data is getting send twice.
And I'm getting response only once. Can anyone suggest why is this
happening
Here is my code
NSURL *url=[NSURL URLWithString:[APIServiceURL geturl]];
NSMutableURLRequest *req=[NSMutableURLRequest requestWithURL:url];
NSString *msgLength=[NSString stringWithFormat:@"%d",[soapMsg1
length]];
[req addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[req addValue:@"http://tempuri.org/InsertPostComment"
forHTTPHeaderField:@"SOAPAction"];
[req setHTTPMethod:@"POST"];
[req setHTTPBody:[soapMsg1 dataUsingEncoding:NSUTF8StringEncoding]];
// Response

Accessing java member variable that has the name "type"
Accessing java member variable that has the name "type"
I am using a java library in which a class has a member named "type". If I
do something like this:
class MyClass{
public MyClass(){
type = 5;
}
public int type;
}
then the java compiler compiles it fine. But if I try to access it from
scala:
val x = new MyClass()
x.type = 10
I get this message:
identifier expected but 'type' found.
How do I work around this issue?
I am guessing this has come up before but I could not find a related
question.

Is there something like has_no_term
Is there something like has_no_term
I have a custom post type named 'Projecten' with a taxonomy called
'fases_projecten', in there i have 'concept', 'inontwikkeling' and
'gerealiseerd'. In my template I'm using the following code for displaying
changes between the sevral fases/terms.
`<?php if( has_term( 'concept', 'fases_projecten' ) ) { ?><div
class="status sActiveConcept"><?php } ?>`
For each fase I have a diffrent openingdiv class, but maybe it will happen
that the users of the website forget to choose a fase, witch mess up the
site completely because the openingtag of the div is missing.
So I was wondering if there exsists something like has no term.
What I already tried is
<?php if( has_term( '', 'fases_projecten' ) ) { ?><div
class="status"><?php } ?>
Also when I make do it like this:
<?php if( has_term( 'concept', 'fases_projecten' ) ) { ?><div
class="status sActiveConcept"><?php } ?>
<?php elseif( has_term( 'inontwikkeling', 'fases_projecten' ) ) { ?><div
class="status sActiveDeveloping"><?php } ?>
<?php elseif( has_term( 'gerealiseerd', 'fases_projecten' ) ) { ?><div
class="status sActiveFinished"><?php } ?>
<?php else( has_term( '', 'fases_projecten' ) ) { ?><div
class="status"><?php } ?>
It will not work, I get a servererror.
I hope I explained clear enough, my english is not so good though

A way to rotate plot in R
A way to rotate plot in R
Rotate a plot (with below rotation setting) seems to be impossible in R
according to Google.
So I am looking for a way to do that, but still no success till now.
Rotation setting :
The rotation center is the origin of plot ({0,0})
The given angle will be the angle between the y axis and the plot.
Here is a code where
a is something depending on angle and x axis length. (I think)
b is something depending on angle and y axis length. (I think)
:
speed <- cars$speed
dist <- cars$dist
plot(speed,dist, xlim=c(0,121), ylim=c(0,121))
xTemp <- speed
speed <- speed + (a)
dist <- dist + (b)
par(new=TRUE)
plot(speed,dist, xlim=c(0,121), ylim=c(0,121), col="red")
Any idea of a and b values ?
Here is for example a code in wich the plot is rotated by about 50 degrees
from the y axis (Notice that is is not a true rotation. speed value is
extended after rotation.. I don't now how to fix it.) :
speed <- cars$speed
dist <- cars$dist
plot(speed,dist, xlim=c(0,121), ylim=c(0,121))
xTemp <- speed
speed <- speed + dist
dist <- dist - xTemp
par(new=TRUE)
plot(speed,dist, xlim=c(0,121), ylim=c(0,121), col="red")

Compare two images irrespective of their size
Compare two images irrespective of their size
I just want to compare images like 2D diagrams (like diagrams in reasoning
questions). And I am giving a drawing editor like paint to draw diagrams.
So suppose one draw a image with a square and a circle and again draw a
image with a little bigger square and a smaller circle. The two images are
same but their figures sizes are different. I want to consider those two
images as same and not different.
Can anyone help me to start with?

Prove $\log_a(b)$ is irrational given that $a, b$ are positive distinct primes.
Prove $\log_a(b)$ is irrational given that $a, b$ are positive distinct
primes.
I know this is a classical proof by contradiction exercise, and there are
full solutions else where, doing a quick search I didn't find any, but I
would approach this question like this:
Suppose $\log_a(b) = \dfrac{p}{q}$ where $p,q \in \mathbb{Z}$ and
$\gcd(p,q) = 1$. Then this implies $a^{\frac{p}{q}} = b$ which implies
$a^p = b^q$. By the fundamental theorem of arithmetic we know $a^p$ has a
unique prime factorization and so does $b^q$. That means $a^p, b^q$ must
have the same unique prime factorization. If $p,q > 0$ then $a|a^p$ but
$a\not |b^q$ contradiction. Similar argument for if one of $p$ or $q$ less
than $0$.
Would this be a correct proof for this question, are there other common
different proofs?
Thoughts after seeing answers: My confusion for not being able to see the
answer right away was because I thought $\frac{p}{q}$ could be negative,
hence there is another possibility in the proof. But $\log_a(b) < 0$
implies $b < 1$ which is impossible since $b$ is a prime.

seven segment display with width
seven segment display with width
I'm in the process of making a seven segment display emulator in python
and have run into a small problem. What I have done is make a list for
each number that has a series of numbers representing a character, like so
["000", "001", "000", "001", "000"] This represents the number 1, with 0
been a space, 1 been a pipe character (|) and 2 been a dash.
This works fine for a width of 1 but I want it to be able to go to any
width. I've tried doing this by multiplying the character count by the
width e.g the number one with a width of two would look like ["000000",
"000011", "000000", "000011", "000000"]
The problem I am having is when it encounters a pipe character it will
print it on the same line rather than underneath it. Like so '| |' when it
should be like
|
|
I've tried using \n to print it on a new line but this messes everything
else up.
Any suggestions on how do this in a better way or how to fix my problem
would be appreciated.

Attack coastal provinces with ships?
Attack coastal provinces with ships?
I've just started my first game as the Ottomans, and my 10 regiment army
is taking a long time to conquer Albania, so I sent some Light Ships,
Galleys and Cogs over to help. They are in the sea next to the province,
but I can't figure out how to have them support the siege or attack the
one enemy ship present.
I selected the Light Ships and clicked the Detach Blockade button, but
that didn't seem to change anything. The image of the city on the siege
popup shows it's a port city if that matters.

Damn Small Linux with XAMPP Linux to create a webserver on a P4 machine or Mele A2000
Damn Small Linux with XAMPP Linux to create a webserver on a P4 machine or
Mele A2000
A couple of days I'am busy to figure out to create a powerful light weight
server that can be used as webserver to serve some simple sites that using
PHP and mod-rewrite.
The P4-box (actually a laptop, dell latitude c640) i'm using came with
windows XP Prof. The problem is that windows consumes more memory and has
some TCP/IP stack problems (it is limited) because it can only serve up to
10 (and 40 with a hack) connections a time.
Before this have also bought a Mele A2000 ARM device (china thingy) that
comes with Android 4.0, a nice little box that is quiet and is power
friendly, just 5 watts. On this device I also tried several things but
doens't get ARM linux on it and all software solutions on Android uses
Lighttpd which does not support mod rewrite like Apache.
So i start searching the net for a linux distro for the P4-box and found
many, to figure out what is the best, it is very difficult for me because
of my Windows background (don't want a headless system). Tried several
ones and then I found Damn Small Linux (or DSL), looks great and works
okay on a very small footprint. Exactly what i'm looking for.
Then I search on DSL+Apache+PHP+mySQL and found the XAMPP Linux version (I
use also XAMPP on Windows to test websites, and found a blog that XAMPP
must be working on DSL). I found only information how to do it but there
is no iso or disk image around with these two worlds combined (at least i
didn't find it).
I tried to setup a diskimage (2GB) with use of VMWare, that is working
great. The idea is to first try it in VMWare and after that convert the
disk to a physical disc without damaging systems or hardware. I have used
the DSL install to setup a debian installation (the "install to harddrive"
option in the tools menu. Reboot and works okay.
After this i downloaded XAMPP Linux
(http://www.apachefriends.org/en/xampp-linux.html) and follow the
instructions on this page. Installed it as superuser but get errors at the
install, one about SQL (something with syntax error in a command-line
utility) and one error the end (something I didn't understand) but install
proceeds and completes.
Then I tried to run 'lampp' or 'xampp' and the only thing I see is
floating point exceptions (see image) and doesn't look ok.
In short, my questions are:
Is there a DSL+XAMPP image around that I can use (can make my life much
easier ;-))
If not, what i'm doing wrong (is it really possible or is there something
wrong with the latest version of both?)
Is there a lightweight distro with XAMPP installed or
PHP+Apache+mod_rewrite+mySQL available? ARM or x86?
Or is it better to take my hands of this and try to figure out to hack
windows stack to get more connections
Or do you have other suggestions?

many, to figure out what is the best, it is very difficult for me because
of my Windows background (don't want a headless system). Tried several
ones and then I found Damn Small Linux (or DSL), looks great and works
okay on a very small footprint. Exactly what i'm looking for.
Then I search on DSL+Apache+PHP+mySQL and found the XAMPP Linux version (I
use also XAMPP on Windows to test websites, and found a blog that XAMPP
must be working on DSL). I found only information how to do it but there
is no iso or disk image around with these two worlds combined (at least i
didn't find it).
I tried to setup a diskimage (2GB) with use of VMWare, that is working
great. The idea is to first try it in VMWare and after that convert the
disk to a physical disc without damaging systems or hardware. I have used
the DSL install to setup a debian installation (the "install to harddrive"
option in the tools menu. Reboot and works okay.
After this i downloaded XAMPP Linux
(http://www.apachefriends.org/en/xampp-linux.html) and follow the
instructions on this page. Installed it as superuser but get errors at the
install, one about SQL (something with syntax error in a command-line
utility) and one error the end (something I didn't understand) but install
proceeds and completes.
Then I tried to run 'lampp' or 'xampp' and the only thing I see is
floating point exceptions (see image) and doesn't look ok.
In short, my questions are:
Is there a DSL+XAMPP image around that I can use (can make my life much
easier ;-))
If not, what i'm doing wrong (is it really possible or is there something
wrong with the latest version of both?)
Is there a lightweight distro with XAMPP installed or
PHP+Apache+mod_rewrite+mySQL available? ARM or x86?
Or is it better to take my hands of this and try to figure out to hack
windows stack to get more connections
Or do you have other suggestions?
how to check if a specific user is signed into google hangout
how to check if a specific user is signed into google hangout
Is there an API call to check if a specific user (whose google+ id is
known) is signed into Google Hangout or not ?
The application I am working on requires me to show a Google Hangout
button to customer X only when customer Y is already logged into a Google
Hangout.
I have already checked the People Google+ API as well as the Hangout API
and I cannot find any call will provide me this info.
Please let me know if this is possible.
Thanks,

iOS Facebook login, handle different access tokens and determine users identity
iOS Facebook login, handle different access tokens and determine users
identity
I have a couple of questions regarding facebook integration and
authentication in my social networking iOS application.
First of all, Users of my application are required to create an account
and login before any content is available to them.
I have a separate backend system, so regular account registration inside
my application is supported. When a user is logged in to an account he or
she is supplied an access token which is used for future backend-requests,
such as image-uploads.
Secondly, A user can choose to log in with Facebook, and thereby acquire
an access token from the successfully opened FBSession.
This leads to my first question: How do I use the access token acquired
from Facebook to authenticate my users with my backend system? Should I
send the acquired token to my backend and have the system use that token
for this particular user until further notice, or is there another way to
go about this?
--
Now lets say that I solved the problem in the first question...
My second question: Imagine that a user created an account and logged in
the normal way (i.e. without facebook) The next time that user wants to
use the application, he or she chooses to log in with facebook.
Now, In my backend-system, how would I know that these two users are the
same, connect them and thereby be able to load the same content for both
cases? Is it even possible to have hybrid accounts that supports double
logins like that? A regular registration only requires email, username and
password, so I cannot think of a way to determine that a
facebook-loggedin-user is the same user as a normal-loggedin-user.
I Hope the above makes sense.

Script works with PHP 5.4.16, but not PHP 5.3.3... where is the faulty code?
I'm a beginner in php, and... I was just trying to create this... dynamic
indexing/document_display script using php... What I was trying to do
isn't really important to the question, however. The thing is... my script
does exactly what I want it to do, when hosted on a WAMP server with php

error

creating a generic static method in java
creating a generic static method in java
I wanted to create a static method which prints the contents of an array.I
wrote one for String[] as below
public static void print(String[] a){
for(String x : a){
System.out.print(x+", ");
}
System.out.println();
}
I thought I could create a method which takes in a generic type ,and
modified the code as below
public class ArrayPrinting<E> {
public static void printArray(E[] a){
for(E x : a){
System.out.print(x+", ");
}
System.out.println();
}
public static void main(String[] args) {
String[] a = {"A","B","C","D","E"};
}
}
But,this gives a compiler error
'Cannot make a static reference to the non-static type E'
So,how do I create such a method?or is it impossible ? Since this is a
static method, I wonder how I can invoke the method without creating an
instance. A call like
ArrayPrinting<E>.printArray(a) doesn't look right ..
Can someone help?

wpf do propertychangedcallback's occur immediately on propertychanges?
wpf do propertychangedcallback's occur immediately on propertychanges?
My general understanding is that when the propertychanges, the local
callback is immediately performed. So I can assume that happens
immediately. However, a bound property's callback will not take place till
the binding propagates, which may not occur immediately. is this correct?

Wordpress stylesheets and other files not linking up
Wordpress stylesheets and other files not linking up
I've uploaded a clients wordpress site to a test domain: 101share.co.uk .
I had everything working on localhost and changed the urls and stuff
before uploading, from http:// localhost/wincheapguesthouse/ to
http://101share.co.uk .
After uploading and importing the database the result I get seems to be
that many files are not being found, but they are there. In the source
code if I look for , it can't find it. But if I look for or
"http://101share.co.uk/wp-content/themes/retlehs-roots-16aad54/assets/css/app.css"
Then I'm able to find it.
Have I got something wrong with the data base or is there a url I need to
change, I can't change each link because I don't know exactly how much it
is effecting.
I stressing out a little over this because it's a clients site and I need
to get things working for them to see. So any help would be very much
appreciated.

Server Socket disconnects and stops listening
Server Socket disconnects and stops listening
This is a problem I never figured out. I've asked many people, and they
don't even know. Anyways, lets get to the problem. Here's what I tried to
do... Create a client and a server. The client connects to the server, and
sends a message to it every 3 minutes (I reduced the time for testing).
There has to be two independent threads however (one for the client and
server). What I found was, the client would continue to send messages, but
the server would no longer listen on port 1234.

PrintWriter(sendChat.getOutputStream());
while(true){
Thread.sleep(1000); // normally
180000
writer.println("Hello Server!");
}
}catch(Exception err){
err.printStackTrace();
}
}
}).start();
}
}

Is there a way to use an existing function as a part of a class? If yes, how?
Is there a way to use an existing function as a part of a class? If yes, how?
I have a function that I want to use in different classes. Is this possible?
Example:
int getNumber()
{
// do something here that will use some values like:
int number = num * pi;
return number;
}
class Human
{
int num;
// other member
int getNumber(); // same as above
}
class Robot
{
int num;
// other member
int getNumber(); // same as above
}
The getNumber() function can be short as return num; or long depends on
the computation that will happen inside the function.
The num value inside the getNumber() is the num member of both Human and
Robot class. Although, these classes do not have the parent-child or
friend relationship.

Import single csv file with one data field going to separate table
Import single csv file with one data field going to separate table
I know this one is probably a long shot but I thought I would at least
ask. Say I have a csv file with a list of Products with the following 4
columns/data fields (Product ID, Name, Alias, UOM) that I would like to
import into a database that has 2 tables. One table is the Product table
(Product ID, Name, UOM), second table is Product Alias table with these 2
columns(Product ID, Alias), where each Product ID may have 0 to many alias
names. Is there any way I could treat the Alias column different by the
fact it has a different separator between the comma's like ";" or a period
"." to separate the 0 to many alias names for a given Product ID.
Therefore during the csv import, when it gets the 3rd comma, it would
import that data into this 2nd table but import a new record with
repeating Product ID's for as many alias names are in that comma field.
Hopefully I explained that well enough, let me if I didn't. I'm more
interested in the possible processing of doing this regardless of what
code that is being using but python would be the preferred route.

I have a row of icons on my page and i want to create a wave animation
effect when user hovers over them with the cursor.
I'm using this basic code for starters:
$('#icons > li')
.hover(function() {
$(this).animate({
'top': (-1 * hover_distance)
}, hover_speed);
}, function() {
$(this).animate({
'top': 0
}, hover_speed);
})
;
And it looks OK. But there is one issue: when you move your cursor
frantically over the icons, the animation queue for every icon is becoming
filled with lots of actions (up, down, up, down, up, down, etc) and icons
is going up and down lots of times even if you stop to interact with the
icons.
I want my icons to complete only one cycle (up and down) and then stop the
animation. I'm looking for a most elegant (short, simple, light) solution
for this.
P/S: And you can't just use stop() because it will prevent the "wave
effect" (i.e. when you move your cursor with one fast stroke over the
icons and they move up and down in response, like a real wave).

C: Trying to free malloc'd char array returned from function results in an error
C: Trying to free malloc'd char array returned from function results in an
error
I have a function to convert a short to a byte array here
char *GetBytesShort(short data)
{
char *ptr = (char *) malloc(sizeof(short));
memcpy(ptr, &data, sizeof(short));
return (char *) *ptr;
}
And, in my main.c, I call the function like this
char *data = GetBytesShort(10);
free(data);
However, whenever I try to free the memory, I get an error First-chance
exception at 0x5896586E (msvcr110d.dll) in Project1.exe: 0xC0000005:
Access violation reading location 0x00000004.
If there is a handler for this exception, the program may be safely
continued.
I'm using Visual Studios 2012 Ultimate edition. I've already set the
language to C in Properties -> C/C++ -> Advanced -> Compile As, but to no
avail. And my files have the .c extension, and not the .cpp
Thanks in advance!

Java Main Method, Parameters Differences
Java Main Method, Parameters Differences
I've started learning Java and I was wondering the difference between:
public static void main (String [] args) {}
and
public static void main (String args[]) {}
As you can see they look almost exactly the same but my question here is,
should the '[]' be before the args or after the args? I have a Java
beginners guide and it shows me examples with the '[]' after the args. I
would be grateful if someone could tell me the correct way.
Thanks!.

How to send keystrokes (F5) from terminal to an process?
How to send keystrokes (F5) from terminal to an process?
I'm using an Raspberry Pi in combination with Chromium (kiosk mode) to
show up some stats. The Pi doesn't have an connected keyboard so I
searched for a solution to send keystrokes from the terminal to the
Chromium (tab) process. Normal input does work but how do I send something
like F5 (special key; browser refresh) via this solution?
# pidof chromium

BIDS "Start Debugging" button not working
BIDS "Start Debugging" button not working
This is a very strange issue. In BIDS/Visual Studio, the "Start Debugging"
button does not run the active package that I am working on. Instead it
opens another package in the project (always the same one) and runs that
one instead. I can only run the active package by right clicking on it in
Solution Explorer and selecting "Execute Package". I run BIDS on three
separate machines and the other two machines do not do this. Is this
button programmable? I have not found any setting for this button.
Has anyone else seen this?

While loop in another while loop to echo data from SQL
While loop in another while loop to echo data from SQL
I have 2 tables, table 1 and table 2.
I want to echo all in table 1, an each time I echo all in table 1 I want
to echo all in tabel 2.
I know I can't write a code this form:
while($var = mysqli_fetch_assoc($result))
{
echo $var['data'];
while($var2 = mysqli_fetch_assoc($result2))
{
echo $var2['data2'];
}
}
So how am I supposed to write the code ???

Flash AS3 run function after Exit frame
Flash AS3 run function after Exit frame
i really need some AS3 Script for run some function when i leave a specfic
frame.
my reason is to put some function to stop video and resume my sound of mp3
player AFTER i exit the frame that contain FLV playback .
i use this script and it`s work great in FLash projector but
stage.invalidate(); cause the Third party application maker like Swfkit
and Zinc Not responding after i try to exit from flv playback frame.
Here is my Script :
stage.invalidate();
mene.addEventListener(Event.RENDER,exitingF);
mene.addEventListener(Event.REMOVED_FROM_STAGE, removedF);
function exitingF(e:Event):void{
controller.gotoAndStop(2);
pausePosition = sndChannel.position;
sndChannel.stop();
isPlaying = false;
}
function removedF(e:Event):void{
mene.stop();
controller.gotoAndStop(1);
sndChannel = soundClip.play(pausePosition);
isPlaying = true;
}
all i need is some another way to say flash run some script right after
exit specfic frame ( go to another frame )

how do i split large SQL database backup files in .net?
how do i split large SQL database backup files in .net?
I am working on backing up and restoration of SQL Database. I am new to
this.I have an issue related to Backup process. I have SQL database and I
am using BACKUP and RESTORE classes to perform backup and restore of
database. I want to make my program more efficient using split backup. I
have aprx 15 to 20 GB of data. so I want to split my my backup files in
specified limit lets say 8-10 GB. I can do this using below SQL
statements:
BACKUP DATABASE AdventureWorks
TO DISK = 'C:\Backup\MultiFile\AdventureWorks1.bak',
DISK = 'C:\Backup\MultiFile\AdventureWorks2.bak',
DISK = 'C:\Backup\MultiFile\AdventureWorks3.bak'
GO
But I want to do this by using Microsoft.SqlServer.Management.Smo.Backup
classes. And I want to get the size of my backup files. Because my
criteria is to split file if my database size exceeds 10 GB otherwise it
will not split my file. SO my issue is how can I get Size of my database
when taking backup. Looking forward to this and Sorry for inconvenience.
Thanks in advance. Quick response is appreciated.

Exception not thrown Java
Exception not thrown Java

The catch statement (Line 1) does not handle the overflow exception as
such the output keeps on printing "asdsdf" without throwing an exception.
Can anyone tell me why an infinite loop is not handled as an exception ?.
Or that's the way it's designed and supposed to work ?

Reduce fan speed of ATI GPU with radeon open source driver
Reduce fan speed of ATI GPU with radeon open source driver
I have a Radeon HD 6950 connected to two screens on a machine running
archlinux.
Recently I changed from the proprietary to the open source driver due to
dropped catalyst support. Unfortunately by default the fans are very noisy
by default - apparently the power saving mechanisms do not work properly.
I set /sys/class/drm/card0/device/power_method to profile and
/sys/class/drm/card0/device/power_profile to low. This seems to work
# cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 800000 kHz
current engine clock: 249990 kHz
default memory clock: 1250000 kHz
current memory clock: 1250000 kHz
voltage: 900 mV
PCIE lanes: 16
Unfortunately it does only help a little with the fan noise. I also tried
dynpm which doesn't really seem to have an effect (possibly due to the
dual head setup).
Previously, with the catalyst drivers, I had issues with fan noise after
suspend, but I was able to use the "ATI Overclocking Utility" to reduce
both shader and memory frequency which muted the fans.
Also I have dual boot windows running and there is no issue with fan noise
in idle on Windows.

QDialog not painting in loop
QDialog not painting in loop
So I have a QDialog class that's launched from a QMainWindow. The
constructor sets up the UI. I declare the object in the QMainWindow, then
i call the method that loops in the QDialog class. The result is that when
the QDialog is shown(dialog->show() is in the constructor) the window
appears without the layout. After the loop completes the layout is then
shown.
I've tried using exec() instead, but then the method does not execute
until after the dialog is closed.

recording live stream video from tv card using ffmpeg at window
I want to record live stream every 1 second from tv card(tv signal) using
ffmpeg in window.
first of all, to record live video from tv card, I tried below.
First I tried this.
ffmpeg -list_devices true -f dshow -i dummy
then the result is

so I tried
ffmpeg -f dshow -i video="SKYTV HD USB Maxx Video Capture" -r 20 -threads
0 D://test.mkv
But it didn't work. the Error message is
"[dshow@000000000034d920] Could not run filter

I use the device called 'SKYTV HD USB Maxx Video Capture' for getting tv
signal(TV card).
The First way deosn't work, I tried different way.
ffmpeg -y -f vfwcap -i list
then the result is "

so I tried
ffmpeg -y -f vfwcap -r 25 -i 0 D://out.mp4
then, there is some out.mp4 file in D drive but the file is nothing. (I
think it is not TV signal)
what should i do to record live video every 1 second from tv card(tv

tvcard(Because I want to get tv signal, there are many channels).
Please help..!

Link to a different page within an included file, to be loaded on the same parent file
Link to a different page within an included file, to be loaded on the same
parent file
I hope this question makes sense because it seems simple, yet I can't work
out exactly how to word it in an understandable way.
Basically - I have an Ajax system for loading content onto an HTML file
via a seperate PHP file. This is to not need the actual page the browser
has loaded to change, only the content.
What I would like to do it be able to create a link WITHIN one of the
loaded content pages, which will change the content to another page via
the parent. For example:
Load the 'menu' page using Ajax, onto a div contained in the main page
Click a link on the 'menu' page, and a different page is loaded onto the
same div on the main page
Cheers

link_to path ActiveRecord call
link_to path ActiveRecord call
I have users and projects, and I'm trying to create a link to the project
by searching for the project using an ActiveRecord call. This is my
link_to:
<%= link_to "Project ABC" User.first.projects.where('title' => 'Project
ABC') %>
I know that this is not in the routes.rb, so how would I be able to make
it so I can do something like this where I write a query to get the
project and then show it? Would I do something like:
<%= link_to "Project ABC"
show_project_path(User.first.projects.where('title' => 'Project ABC')) %>
If so, would I need anything special in my controller?

Thanks.

Can a UICollectionViewLayout have supplementary view in front of cell?
Can a UICollectionViewLayout have supplementary view in front of cell?
I'm aiming to have a static header with the cells passing underneath as
the user scrolls. I've created the functionality I'm looking for, however
if the supplementary views have a high zIndex than the cell, it blocks the
didSelectItemAtIndexPath: method.
Is there a way to work around this?

This is what I have already. It searches column B in sheet 1 for #N/A and
deletes the row.
Sub DeleteErrorRows()
On Error Resume Next
Range("B:B").SpecialCells(xlCellTypeConstants, 16).EntireRow.Delete
On Error GoTo 0

What I would like is for it to copy that row onto sheet 2 and then delete?
So I can have a record of what was deleted.
Any help would be much appreciated. Thanks!

PHP MVC- Integrating Controllers and Views
PHP MVC- Integrating Controllers and Views
I am trying to build a web application using MVC design pattern in PHP.
But before starting I tried to implement a small mvc application and
cannot figure out how to deal with following scenario.
I created Index_Controller ,Index_Model and index directory which acts as
controller, model and view for Index page respectively. I tried to
integrate FileUploader in that Index page and created
FileUpload_Controller , FileUpload_Model (because I will store Image
Captions and other data related to file(s) in database) and fileupload
view. Now I am able to view Index Page from this URI :
http://localhost/mvc/index/ and the FileUpload Plugin using this URI :
http://localhost/mvc/fileupload/ but how could I integrate the
FileUploader Plugin in Index and some other (if required) pages. Accessing
http://localhost/mvc/fileupload/ only is meaning less and It should be
integrated in some other views.
I am confused on what should be created using Model , View And Controllers
. I think the way I have created FileUpload Plugin is wrong. I used MVC
for FileUpload because I have to deal with Database also. I think I am not
clear on for what type of entity should I create Models , Views and
Controllers.
Any guideline and help will be much more appreciated. Thank you.

dynamic routing with muiltiple $routeParams AngularJS
dynamic routing with muiltiple $routeParams AngularJS
Using parameters as identifiers to fetch content:
$routeProvider.when('/:category', {
templateUrl: '/views/category.html'
});
But what if I have a second tier?...
$routeProvider.when('/:category/:service', {
templateUrl: '/views/service.html'
});
This works fine for following links with $locationProvider.html5Mode(true)
<a href='/{{items.category}}/{{item.service}}'></a>
However directly invoking a link through address bar
x.com/xCategory/xService does not work.
$routeProvider matches :category before seeing second parameter :service
templateUrl for the /:category route is always taking precedence.
x.com/xCategory/xService will always fetch templateUrl for x.com/xCategory
I'm using nginx rewrite rules so I can fully support pushState:
location / {
try_files $uri /index.html;
}
What is going on here?

Algorithm as figure and without italic and bold formatting?
I want to include an algorithm in my latex document, however without
printing most of it in italic and all the keywords in bold font like it's
done by default by e.g. the algorithmicx package. I like this simple
style:
(screenshot of a part of page 3 of
http://research.microsoft.com/pubs/68869/naacl2k-proc-rev.pdf)
The only thing I'd like to add to this style are line numbers. Can anyone
help me, how I get the formatting of the screenshot and the line numbers?
Thanks :-)
So, here is what I have until now:
\documentclass{article}
\usepackage{algorithm}
\usepackage{algpseudocode}
\usepackage{algpascal}
\begin{document}
\alglanguage{pascal}
\begin{algorithm}
\caption{Paull's algorithm}

\State Assign an ordering $A_{1}, ..., A_{n}$ to the nonterminals of the
grammar.
\For{i = 1}{n}
\Begin
\For{j = 1}{i-1}
\Begin
\State for each production of the form $A_{i} \rightarrow A_{j} \alpha$
\End
\End
\end{algorithmic}
\end{algorithm}
\end{document}
This ends up as
Based on this I want the following changes:
do and begin shall be on the same line
end shall be vertically aligned to it's associated for (see first
screenshot of this post).
Integration as a figure or at least without a black border and with a
caption below the algorithm would be prefered
bold formatting for keywords should be turned off

function wpa_date_archive_post_types( $query ){
if( $query->is_main_query() && $query->is_date() ):
$query->set( 'post_type' , array( 'movie' ) );
$query->set( 'tag' , '1994' );//For testing pupose I put a
hard coded value...
$query->set( 'post_status' , array( 'publish' ) );
endif;
}
add_action( 'pre_get_posts', 'wpa_date_archive_post_types' );
WP generates the following query:
SELECT
SQL_CALC_FOUND_ROWS wp_posts.*
FROM
wp_posts
INNER JOIN
wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
WHERE
1=1
AND
YEAR(wp_posts.post_date)='1994'--WP gets 1994 here from an URL
parameter (year)
AND
(wp_term_relationships.term_taxonomy_id IN (24) )
AND
wp_posts.post_type IN ('movie')
AND
(wp_posts.post_status = 'publish')
GROUP BY
wp_posts.ID
ORDER BY
wp_posts.post_date DESC
LIMIT
0, 5
I want to remove the following line from the final query:
AND
YEAR(wp_posts.post_date)='1994'
I tried to add this PHP code
// ...
if( $query->is_main_query() && $query->is_date() ):
$query->set( 'post_type' , array( 'movie' ) );
$query->set( 'year' , 0 );
$query->set( 'tag' , '1994' );
$query->set( 'post_status' , array( 'publish' ) );
endif;
// ...
But I get a blank page. How can I disable year from sql query ?

Javscript Code isn't working under XP
Javscript Code isn't working under XP
I am using this JS code for show and hide some div elements on my side -
it is working perfectly on W7/W8 and all browsers, but for XP it doesn't
work at all, am I something missing about JS libraries supported in XP or
something?
Thanks for any replies in advance.
<script type="text/javascript">
var divState = {};

divState[div] = false;
}
}
divid.style.display = (divid.style.display == 'block' ? 'none'

Restore Whole Sticky Note on Windows 7
Restore Whole Sticky Note on Windows 7
I accidentally removed my Sticky Note on Windows 7 and now I've been
trying to get it back. I searched at %AppData%\Microsoft\Sticky
Notes\StickyNotes.snt and could see some of the text that was in my Sticky
Note. How can I get back all of the text? I used signs like * and | in the
note, will this cause any trouble?

I've a variable like:
<?php

?>
my html is like:
<input type="text" value="<?php echo $val; ?>" name="xyz" />
But the input can't show all the text because having "/' is in the middle
of them. But I need the text field to show abc"def'ad . Any idea how to do
it using HTML (not js)?

How to customize a backend running job completion message?
How to customize a backend running job completion message?
Here is the situation, I am running a command (my own executives), in bash
shell (Ubuntu), say something like this:
[newbie@office currentCaseAFolder]$ FEMSolver &
So that the FEMSolver job is now running in backend, and let's say it
needs around five to ten minutes. But I have more than one cases. so
[newbie@office currentCaseAFolder]$ cd ../currentCaseBFolder
[newbie@office currentCaseBFolder]$ FEMSolver &
[newbie@office currentCaseBFolder]$ cd ../currentCaseCFolder
[newbie@office currentCaseCFolder]$ FEMSolver &
[newbie@office currentCaseCFolder]$ cd ../currentCaseDFolder
[newbie@office currentCaseDFolder]$ FEMSolver &
[newbie@office currentCaseDFolder]$ cd ../../postprocessingFolder
After a coffee time, I come back, and hit return key, some simulations
have finished. so it will show me
[2] + Done FEMSolver &
[4] + Done FEMSolver &
[newbie@office postprocessingFolder]$
But this does not give me the clear information from which folder the job
was sent!! I hope it could somewhere and somehow be customized to have
this effect:
[2] + Done FEMSolver & (from folder currentCaseBFolder)
[2] + Done FEMSolver & (from folder currentCaseDFolder)
[newbie@office postprocessingFolder]$
Any ideas?

Controlling JComponents from other classes
Controlling JComponents from other classes
Is it possible to control instances like variables, jcomponents, timer in
other external classes?
For example this is my Class1
public class Class1 extends JFrame {
JLabel lbl = new JLabel("Hello");
public Class1() {
super("Class1");
Container c = getContentPane();
setLayout(null);
c.add(lbl);
lbl.setBounds(0,0,100,20);
Class2.process();
setSize(200,100);
setLocationRelativeTo(null);
setVisible(true);
}
public static void main(String var[]) {
new Class1();
}
}
You can see there's Class2.process(); Here's the other class externally
but in the same folder
public class Class2 {
public static void process() {
// I want to control lbl from Class1 class inside this method like
// lbl.setVisible(false);
}
public static void main(String args[]) {
//
}
}
Is it possible? Sorry. I can't find answers on other website.

ArrayList of ArrayLists in Recursion
ArrayList of ArrayLists in Recursion
I've been working on a larger project, and ran into a problem which I have
replicated here in a much simpler fashion. What I'm trying to do is to add
an ArrayList of Integers into another ArrayList. The problem is that every
ArrayList I add into the larger ArrayList gets updated as if they were all
the same.
public class RecursionTest {
static ArrayList<Integer> test = new ArrayList<Integer>();
static ArrayList<ArrayList<Integer>> test1 = new
ArrayList<ArrayList<Integer>>();
public static void testRecurse(int n) {
test.add(n);
if (n % 2 == 0) {
test1.add(test);
}
if (n == 0) {
for (ArrayList<Integer> a : test1) {
for (Integer i : a) {
System.out.print(i + " ");
}
System.out.println();
}
return;
}
testRecurse(n - 1);
}
public static void main(String[] args) {
testRecurse(10);
}
}
The output I get is:

Can someone explain to me what is happening here? And perhaps suggest a
work around for such a situation.
I've been working on a larger project, and ran into a problem which I have
replicated here in a much simpler fashion. What I'm trying to do is to add
an ArrayList of Integers into another ArrayList. The problem is that every
ArrayList I add into the larger ArrayList gets updated as if they were all
the same.
public class RecursionTest {
static ArrayList<Integer> test = new ArrayList<Integer>();
static ArrayList<ArrayList<Integer>> test1 = new
ArrayList<ArrayList<Integer>>();
public static void testRecurse(int n) {
test.add(n);
if (n % 2 == 0) {
test1.add(test);
}
if (n == 0) {
for (ArrayList<Integer> a : test1) {
for (Integer i : a) {
System.out.print(i + " ");
}
System.out.println();
}
return;
}
testRecurse(n - 1);
}
public static void main(String[] args) {
testRecurse(10);
}
}
The output I get is:
10 9 8 7 6 5 4 3 2 1 0
10 9 8 7 6 5 4 3 2 1 0
10 9 8 7 6 5 4 3 2 1 0

Rails: Passing variable from form to model
Rails: Passing variable from form to model
I have a form, where users can upload a picture and can choose a watermark
from a list. The value in the field is then the URL of the watermark (for
simplification in development). I need to pass the chosen watermark_url to
the model, so that rmagick can add the watermark. I use paperclip for the
uploads.
In my model I have the following:
class Image < ActiveRecord::Base
...
attr_accessor :watermark_url
has_attached_file :picture, :processors => [:watermark], styles: {
thumb: '100x100>',
medium:{
geometry: '300x300>',
watermark_path: Rails.root.join(watermark_url),
position: "Center"}
}
end
watermark_url is a field in the form and in the database (which would not
be necessary). Then I get the following error: undefined local variable or
method `watermark_url'.
Am i missing something here?
Thank you in advance for helping!

Decentralized Task Scheduling Techniques in .NET
Decentralized Task Scheduling Techniques in .NET
I have been trying to learn more details on CLR 4.0. and the ThreadPool
and the different strategies that Microsoft recommended. I consider myself
fairly up-to-date on a lot of these topics, and use threading and
concurrent code on a daily basis.
I have been goign back through the Parallel Patterns and Practices again
recently, and am a bit caught on the Decentralized Scheduling Techniques
section which gives a brief overview of 'Work Stealing' and local vs
global thread queues.
The questions I have are:
1) Is work stealing opt-in or opt-out? Same for using local thread queues?
Or does this happen by default with CLR 4.0?
2) Do we have control over whether we are using local or global thread
queues? If so, through what API calls?

Which iOS version to target
Which iOS version to target
I will describe my situation briefly and would be very grateful for some
competent advice.
I have recently started learning iOS development and I am half way on this
book:http://rads.stackoverflow.com/amzn/click/0321821521 which is for
iOS5.
Now, there maybe an application I will start writing in a month or so. My
first questions were: which iOS version should I target, iOS6, or iOS7?
My one concern is that I've seen that supporting both iOS6 and iOS7 maybe
a lot of work/complicated, and due to my level of experience I am not sure
if this is good thing to do??.
Shall I still go on with the book I mentioned?
I'd be grateful if someone can answer my questions.

Python Function Return
Python Function Return
If I want to return more that one variable from a function in Python I
have been doing the following:
def foo():
firstName = 'Bob'
lastName = 'Jones'
return [firstName, lastName]
Then if I wanted to find only the first name I would do this
[firstName, dummy] = foo()
However, say I initially had the function
def fooInitial():
firstName = 'Bob'
return firstName
and I called this from many parts of my code, if I wanted to add the
lastName as another output the way I have been doing, I would have to
change everywhere else in my code that was calling it.
Is there a way to do something similar to Matlab where calling a = foo()
gives me the first name (not the first and last in a list) and [a,b]=foo()
gives me the first and last?
