What seems wrong with this bash script?
I found an initscript that for some reason insists on starting the
specified application as the root user. I can't wrap my head around why it
is doing this, any hints? The script runs on Redhat Enterprise Linux 5.9.

How remap CTRL-key to Alt right (tried everything)
How remap CTRL-key to Alt right (tried everything)
My specs: Xubuntu 13.04, which uses (what I believe) Xorf as X Window
Manager.
Intro: some weeks ago I switched to Linux (Xubuntu). I configured
everything to work only with my keyboard without ever using the mouse.
Works like a charm. But recent, I wanted to remap the [ctrl] to
[capslock]. ~/.xmodmap seems not working. I found the answer here:
**/usr/bin/setxkbmap -option "ctrl:nocaps"** does the trick. I putted the
command as autostart.
Works fine until I got RSI-like issues with my left pink the last days. My
pink tingles weird and causes much pain at the end of day (even I'm using
ergonomic keyboard!). I tried everything to avoid this, like the correct
posture and taking breaks, weight lifting. Nothing helps. Then I looked
closer to my keyboard flow. I noticed I use the spacebar most, on second
the [Capslock]-button that behaves like [ctrl]. But I have no pain in my
thumbs. I dont use the right [Alt], so it would be better if I remap the
[ctrl]-key to [alt-key], so I can activate [ctrl] with my thumb.
What have I done?
Tried this: /usr/bin/setxkbmap -option "ctrl:alt_R" Not working.
Tried this: /usr/bin/setxkbmap -option "ctrl:Meta_R" Not working.
Tried the .xmodmap configuration. I start xev, pressed the right [alt] key
and it gives me keycode 108. [ctrl] gives me 37. So i create up ~/.Xmodmap
and map: keycode 108 = Control_L and reboot. Not working.
I've searched through the forums a lot, but have not found a solution. Any
suggestions how manage the right Alt+key behave as [ctrl]-key?
Thanks in advance for your appreciated help.
================== Edit: found the answer! Without the open source spirit,
I would never able to find my way here. And everyone benefits too!
The answer is..... bumbumbrrrrr...

Text alignment issue in a quote banner
Text alignment issue in a quote banner
as you can see on this JSFiddle and on picture below, I'm struggling to
get the signature placed as I want in my banner (I want it at the bottom

line of the text is not perfectly aligned horizontally to the middle of
the block (there's more space to the right than to the left). How could I
fix this and have full control on the signature position? Many thanks,

In PHP would this be deemed correct?
In PHP would this be deemed correct?
I already wrote a post about an issue I had before about this but I had
that issue taken care of. Like my last post I have a form, text-box and a
button. I have everything done with this including Printing the original
word, Printing the number of characters in the word, Printing the word in
all caps and Printing the word in reverse order. My only issue I'm having
is trying to get whatever text I enter and then click the button to output
to Print the first letter of the word and Print the last letter of the
word. I've been doing a lot of looking around of PHP.net and I found that
substr is used to return a part of a string that I could use. The only
issue is when I write the code for it and try to execute my program it
errors out on that specific line. I'm not looking for the answer but could
someone just take a look and see what I'm doing wrong because I understand
everything completely but this is the only thing I'm hung up on.
$first = substr($_POST['entertext']);
echo "The first letter of the word is " . $first. "<br />\n";
$last = substr($_POST['entertext']);
echo "The first letter of the word is " . $last. "<br />\n";

Jersey framework override contoller methods or REST request filtering
Jersey framework override contoller methods or REST request filtering
I need to implement a controller for processing requests whith filter use
Jersey framework. For example:
.../myservice/book - display a list of all books.
.../myservice/book?chapter=1,5 - display 1 and 5 books chapters.
.../myservice/book?page=10,50 - display 10 and 50 books pages.
.../myservice/book?chapter=1,5&page=10,50 - display 1 and 5 books chapters
and only 10 and 50 book pages.
I can't use .../myservice/book/chapter/1,5/page/10,50, because possible
situation: .../myservice/book/7 - display book 7 and filters described
above can be applied here. Is it possible to implement it in this way:
public class TestController {
@Path("/book")
@GET
public Object getBook() {
// return a list of all books
}
public Object getBook(@QueryParam("chapter") String chapter) {
// return books chapters
}
public Object getBook(@QueryParam("chapter") String page) {
// return books pages
}
public Object getBook(@QueryParam("chapter") String page,
@QueryParam("page") String page) {
// return books chapters and pages
}
}
Or to add all kinds of filters in one method and verify the presence of a
large number of conditions?

Postgresql: how to correctly create timestamp with timezone from timestamp, timezone fields
Postgresql: how to correctly create timestamp with timezone from
timestamp, timezone fields
I have a table with a timestamp without time zone. YYYY-MM-DD HH:MM:SS
and a field "timezone" that is either "P" for Pacific or "M" for Mountain.
I need to create a field of type "timestamp with time zone"
Given the two fields I have, is there a way to do this that correctly
accounts for Daylight Saving Time?
Specifically: timestamp: 2013-11-03 01:00:00 timezone: "P" would become:
2013-11-03 01:00:00-07
and timestamp: 2013-11-03 03:00:00 timezone: "P" would become: 2013-11-03
01:00:00-08

MySQL - given multiple associations, how to get latest association for

Let's say I have two tables (non-essential rows omitted):
Table `pages`
page_id | page_key
1 | home
2 | about
and
Table `page_versions`
page_id | page_version | page_title | page_content
1 | 2 | Home | Lorem Ipsum...

If each page has multiple page_versions, how do I query the database such
that I get all pages associated to their latest page_version?
Essentially:

global operator + override clash detection

My code is is clashing with a 3rd party library. I define this:
inline __m128 operator + (__m128 a, __m128 b)

}
but get
error C2084: function '__m128 operator +(const __m128,const __m128)'

I can't change the 3rd party library and they don't #define anything which
identifies this operator as having been defined. Is there a way (perhaps
using SFINAE) that anyone knows of to allow their definition to prevail?

Error moving jQuery slider with iScroll5 beta
Error moving jQuery slider with iScroll5 beta
I'm working on iScroll5 Beta. I want to make a magazine style mobile webpage.
http://bit.ly/1b7FQco
When I swipe left or right, it works well and slider would move to right
position. But there is a problem. When I drag a slider point on bottom
bar, "scrollTo(-320 * e.target.value, 0, 500);" is works well. And then I
swipe up and down on color page, unsuspected page would be shown. I'm not
good at writing English. So I made a movie when I swipe it.

After watching this video, you would know what the problem is.
Here's codes.

var myScroll;
function loaded () {
myScroll = new IScroll('#wrapper', {
scrollX: true,
scrollY: false,
momentum: false,
snap: true,
snapSpeed: 400,
tap: true,
click: true
});
myScroll.on("scrollEnd", function() {
$('#slider-1').val(myScroll.currentPage.pageX);
});
$('#slider-1').bind('mouseup', function(e) {
myScroll.scrollTo(-320 * e.target.value, 0, 500);

I have a segment of code that attaches the current file to an e-mail

Instead of attaching the whole document to this email I want to copy tabs

Flash builder: datagrid remove item - index out of bound
I have an issue wich i can't solve atm, a little helo would be much
appreciated. A local XML file is loaded into a HTTPservice and load the
data into a Datagrid. The local file cotains information about locally
stored files.
Just to be secure and sure, when the AIR app loads, i want to run through
the loaded datagrid and check if the local file exists. If it doens't
exist, i want to detele the row in the datagrid.
Doing that i get this annoying error: The supplied index is out of bounds.
I know that, deleting an element in the datagrid will result in new
indexes wich causes this error.
Thanks for your advice!

class after div "row", with the name ".career-nav", but it didnt work,
then I commented that and started to write mediaqueries. But as I am new
in Foundation Framework I am not sure that I did the right query,
therefore I want to know, which method is the best one for such
adjustement and what I missed in my code. Thank you!

Java Enum Methods
I would like to declare an enum Direction, that has a method that returns
the opposite direction (the following is not syntactically correct, i.e,
enums cannot be instantiated, but it illustrates my point). Is this
possible in Java?
Here is the code:

this.code=code;
}

public int getCode() {

Magento Admin Create Order not showing Custom Options
Magento Admin Create Order not showing Custom Options
I have simple products with custom options in my store. They work
perfectly from the front end, but if I try to add an order from the admin
section, The custom options do not show up.
I only have this problem if the type of custom option is a dropdown, multi
select, radio buttons, or check boxes. If it is a text field, date or
anything else, it works fine.
I am assumming i need to make some changes to something in the

area, but no clue what i should try.
Looking a bit further, I found this

file controls the configure window at about line 320 which calls the
configure window up. Not sure if this helps any

Left menu disappears from screen
Left menu disappears from screen
The problem I'm having is as follows:
This website I'm working on has a left menu, then content. The menu on the
left should be visible at all times. On my screen this works just fine,
but on smaller screens (<=1280pxx720px) the menu will disappear partially.
So what I would like is that either the menu stays there somehow, or some
sort of scroll bar appears (just the vertical scroll bar), so you can
scroll to the menu.
I hope there's someone out there with an answer!

Handling mouse events on a QQuickItem
Handling mouse events on a QQuickItem
I have created a basic QML application which uses QQuickView for creating
a view, and has custom QQuickItems in it. I want to handle mouse events on
one such QQuickItem by reimplementing the mousepressevent(QEvent *)
method. However, when I run the application and click on the QQuickItem,
no call is made to mousepressevent(QEvent *) method.
The header file of the QQuickItem looks like this:
#include <QQuickItem>
#include <QSGGeometry>
#include <QSGFlatColorMaterial>
class TriangularGeometry: public QQuickItem
{
Q_OBJECT
public:
TriangularGeometry(QQuickItem* parent = 0);
QSGNode* updatePaintNode(QSGNode*, UpdatePaintNodeData*);
void mousePressEvent(QMouseEvent *event);
private:
QSGGeometry m_geometry;
QSGFlatColorMaterial m_material;
QColor m_color;
};
Note: I am making use of scenegraph to render the QuickItem.
This is a snippet from the cpp file:
void TriangularGeometry::mousePressEvent(QMouseEvent *event)
{
m_color = Qt::black;
update(); //changing an attribute of the qquickitem and updating the
scenegraph
}
I can handle mouse events from the application but, as per my
requirements, I need to handle it by overriding the method
mousePressEvent(QMouseEvent *event).
I have created a basic QML application which uses QQuickView for creating
a view, and has custom QQuickItems in it. I want to handle mouse events on
one such QQuickItem by reimplementing the mousepressevent(QEvent *)
method. However, when I run the application and click on the QQuickItem,
no call is made to mousepressevent(QEvent *) method.
The header file of the QQuickItem looks like this:
#include <QQuickItem>
#include <QSGGeometry>
#include <QSGFlatColorMaterial>
class TriangularGeometry: public QQuickItem
{
Q_OBJECT
public:
TriangularGeometry(QQuickItem* parent = 0);
QSGNode* updatePaintNode(QSGNode*, UpdatePaintNodeData*);

How do I create a prefix like jQuery does?
How do I create a prefix like jQuery does?
How do I create a prefix like the one jQuery uses? For example, in jQuery
I can use:
$(".footer").css('display', 'none');
and I'd like to enable a similar syntax, like this:
google('.footer').chrome('display', 'none');
I have searched Google for an answer, but couldn't find it.

java client send class and server execute a method from this files
java client send class and server execute a method from this files
Im working on a little project.
My client send a java file :
public class Calc {
public int add(String a, String b){
int x = Integer.parseInt(a);
int y = Integer.parseInt(b);
return x + y;
}
}
My server receive this file in his package. There is no problem for this.
What i want its to excecute 'public int add' in my server with parameter
send by client. For example: my client connects to server. He send
Calc.java and with a String add("1","2") My server receive this and
execute the function to finnaly return the result.
But i dont know how to do this... i just find "execute" but ihavent a main
method in Calc.java
Is this possible to do that ? With what method ?

Why not directly instantiate services in Android?
Why not directly instantiate services in Android?
I was wondering why the direct instantiation of a service class through a
constructor is not recommended. I couldn't find anything related to it.
Here is a very basic example:
Service class:
public class SomeRandomClass extends Service {
private final Context mContext;
public SomeRandomClass(Context context) {
this.mContext = context;
}
}
And inside main Activity/Service:
SomeRandomClass class = new SomeRandomClass(this);
class.someMethod();
The post here states that it is not a good idea to instantiate services
directly and one should use startService() instead but why? If I
instantiate my service like this I have a variable directly to the service
and I can call methods instead of having to bind to it to be able to call
methods on my service.
The only advantage I can see by using startService() is that Android keeps
track of my service but the disadvantage that I have to bind to the
Service to communicate with it. On the other hand by calling the
constructor directly I have easy communication but if my activity/service
get's killed/terminated the "sub" service is killed as well (I'm not using
a activity but other service).
Anything else why it is discouraged?

Calling nc/netcat in python with variable
Calling nc/netcat in python with variable
I am attempting to call netcat/nc from inside a loop, passing the lcv as
the last octet in the command. I am seem to be running into an issue due
to the fact that the variable is in the middle of the command. What I
would like to do is:
for i in 1 to 50
print i
nc -nvv 192.168.1.i 21 -w 15 >> local_net.txt
So far I have tried:
os.system("nc -nvv 192.168.1.",i,"21 -w 15 >> local_net.txt")
and
subprocess.call(["nv","-nvv 192.168.1.",i,"21 -w 15 >> local_net.txt")
Is there an easier way to reference an LVC from within a command executing
a system command?

Seperating intergers from a string properly (no regex)
Seperating intergers from a string properly (no regex)
I need to isolate all integers from a string, list them, and print their
sum and the # of integers. My issue is that my current code will split,
for example, 456 into 4, 5, and 6, and treat them as separate integers.
Unfortunately regex is not an option.
What i have so far:
def tally(text):
s = ','.join(x for x in text if x.isdigit())
numbers = [int(x) for x in s.split(",")]
num=len(numbers)
t=sum(numbers)
print ('There are', num, 'integers in the input summing up to', t)
..
What i need: input:'34 ch33se 34e8 3.4'
output: [34 33 34 8 3 4 ]
im getting now is [3 4 3 3 8 3 4]

Why can't the complier find this operator
Why can't the complier find this operator
I'm trying to write overloads of operator<< for specific instantiations of
standard library containers that will be stored in a boost::variant.
Here's a small example that illustrates the problem:
#include <iostream>
#include <vector>
std::ostream & operator<<( std::ostream & os, const std::vector< int > & ) {
os << "Streaming out std::vector< int >";
return os;
}
std::ostream & operator<<( std::ostream & os, const std::vector< double >
& ) {
os << "Streaming out std::vector< double >";
return os;
}
#include <boost/variant.hpp>
typedef boost::variant< std::vector< int >, std::vector< double > >
MyVariant;
int main( int argc, char * argv[] ) {
std::cout << MyVariant();
return 0;
}
Clang's first error is
boost/variant/detail/variant_io.hpp:64:14: error: invalid operands to
binary expression ('std::basic_ostream<char>' and 'const std::vector<int,
std::allocator<int>>')
out_ << operand;
~~~~ ^ ~~~~~~~
I realize that the #include <boost/variant.hpp> is in an odd place. I'm
pretty sure the problem had to do with two-phase name lookup in templates,
so I moved the #include in an attempt to implement fix #1 from the clang
documentation on lookup. Fix #2 from that documentation isn't a good
option because I believe adding my overloaded operator<< to the std
namespace would lead to undefined behavior.
Shouldn't defining my operator<<s before the #include allow the compiler
to find the definitions?

Finding prominent frequencies from FFT
Finding prominent frequencies from FFT
Im trying to find the prominent peaks in an audio signal (piano recording)
using STFT. This is what Ive done so far 1. Obtain the envelope of the
time domain signal 2. Determine the peaks in the enveloped signal and use
them as note onsets 3. perform FFT for the samples between each 2
consecutive onsets.
Now that I have the FFT, I want to find the peaks corresponding to the
notes played... when i try using the findpeaks function at some points it
says its an empty matrix. Im not sure how exactly to do this so need some
help urgently...... Thank you

adapter to a ListView. The code runs fine doing the last line of onCreate
where I call setAdapter(...) but then it fails in the next line at the end
of onCreate. The code runs without errors when I do comment out the
setAdapter method.
Here are some of the logs.

php resize image on upload
php resize image on upload
I got a form where the user is inserting some data and also uploading an
image.
To deal with the image, I got the following code:
define ("MAX_SIZE","10000");
$errors=0;
$image =$_FILES["fileField"]["name"];
$uploadedfile = $_FILES['fileField']['tmp_name'];
if($image){
$filename = stripslashes($_FILES['fileField']['name']);
$extension = strtolower(getExtension($filename));
if (($extension != "jpg") && ($extension != "jpeg") &&
($extension != "png") && ($extension != "gif")){
echo ' Unknown Image extension ';
$errors=1;
} else{
$newname = "$product_cn."."$extension";
$size=filesize($_FILES['fileField']['tmp_name']);
if ($size > MAX_SIZE*1024){
echo "You have exceeded the size limit";
$errors=1;
}
if($extension=="jpg" || $extension=="jpeg" ){
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
}else if($extension=="png"){
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
}else{
$src = imagecreatefromgif($uploadedfile);
}
list($width,$height)=getimagesize($uploadedfile);

$filename = "../products_images/".$newname;
$filename1 = "../products_images/thumbs/".$newname;
imagejpeg($tmp,$filename,100); //file name also indicates
the folder where to save it to
imagejpeg($tmp1,$filename1,100);
imagedestroy($src);
imagedestroy($tmp);
imagedestroy($tmp1);
}
}

function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
I've wrote some notation in the code since im not really familiar with
those functions.
for some reason, it doesn't work.
when I'm going to the folder "product_images" OR "product_images/thumbs" I
can't find any image uploaded.
Any idea what's wrong with my code? there should be 60px width image, and
25px width image.
NOTE:
variables that you don't know where they were declared such as $product_cn
were declared before that block of code which works prefectly fine(tested
it). If you still want a glance at it, feel free to ask for the code.
Thanks in advance!

Eclipse: Examine classloading problems/how to inspect deeply nested variables in debug view
Eclipse: Examine classloading problems/how to inspect deeply nested
variables in debug view
I am trying to fix some class loading problems that I ran into by
examining why class loaders fail to find the respective offending class
(here: org.eclipse.jdt.internal.compiler.env.INameEnvironment). However,
Eclipse (GGTS to be more precise) fails to show/determine the variable
contents I am interested in in this regard ("path" & "res", see attached
screenshot).
Is it possible to determine them somehow? I was unable to see them in the
variables and watch view (other variables like ucp are inspectable). I
downloaded a SDK from here https://jdk7.java.net/download.html (hoping
that it is a fast debug build) but that does not seem to make a
difference. Maybe there are other means to figure out this sort of class
loading (Class Not Found) problems?
Btw. I am using Groovy/Grails if that matters.

And this div has a absolute position and I have set the

firefox, you can see the right edge of the div cannot move by "20%". Has
someone else encountered with the similar problem before? I really
appreciate your help. Many thanks!

Drop an index in postgresql
Drop an index in postgresql
I had created an index wrongly and now im trying to drop that index. Since
the datas are large for my table, dropping index is taking lot of time. Is
there any other way to drop the index quickly?

Passing an array of ints as an argument in C++?
Passing an array of ints as an argument in C++?
I made a function in C++ to find the length of an array. I find the sizeof
the array passed in the argument and divide it by the sizeof the variable
type. This should work but it always returns 1! Am I missing something
obvious? Or does this have to do with pointers and memory? This is my
code:
#include <iostream>
using namespace std;
int lengthOf(int arr[]);
int main() {
int x[] = {1,2,3,0,9,8};
int lenX = lengthOf(x);
cout << lenX;
return 0;
}
int lengthOf(int arr[]) {
int totalSize = sizeof arr;
cout << totalSize << endl;
int elementSize = sizeof(int);
return totalSize/elementSize;
}
Output (should be 6 instead of 1):
4
1
I am fairly new so excuse me if this is a bad question.

Does my node server need to manually end the response before the function ends?
Does my node server need to manually end the response before the function
ends?
I have a node server and I'm using express to process POST requests to it.
My question is, do I have to call response.end() before my processing
function ends or will that happen automatically?
Why I'm asking is because my server works as expected for the first few
requests, then it starts throwing "request timeout" errors, so I'm trying
to track down the issue.
I should also note that I always send something in the response using
response.send() if that makes any difference.

Distance of two Rectangle Center's Connecting Line Outside of the Rectangles
Distance of two Rectangle Center's Connecting Line Outside of the Rectangles
Well excuse me for the long title, i dont really know how to call it.
I would like you to explain me how to calculate the image's red line's
length, knowing the rectangles position and dimensions.
Context: I need this for a 2d game collision response since when the
length is negative it means not only they are intersecting but also that
length is the distance they have to repel each other to stop being
collided. If there's an easier way to do this, even better.

Calling perl script from perl
I have a perl script which takes 2 arguments as follows and calls
appropriate function depending on the argument. I call this script from
bash, but i want to call it from perl, is it possible?
/opt/sbin/script.pl --group="value1" --rule="value2";
Also the script exits with a return value that I would like to read.

Move an image down
Move an image down
I am developing a webpage for images on a carousel. How can I move an
image down in a DIV, or even center it vertically?
Here is my CSS code:
.carousel .item {
height: 900px;
background-color: #777;
}
.carousel-inner > .item > img {
display: block;
margin-left: auto;
margin-right: auto
}
Here is a URL to the webpage in question to show you that the image is too
high: http://www.canninginc.co.nz/canluciddream/screenshots.html
EDIT
Ok, I have edited the code by changing the:
margin-top: 50px;
I am still after the image to be lower in the div. I can increase the top
margin, but this leaves a white background. What would be the best way to
move the image a little bit lower?

Auto Layout with UITabBarController
Auto Layout with UITabBarController
I'm trying to shift to Auto Layout in my app, but I'm having some trouble
with my UITabBarController. Basically, I have two buttons on my home
screen, and I want them to have equal sizes, one 50 pixels from the top of
the screen and one 50 pixels from the bottom.
The issue is that when I do this:
NSArray* verticalConstraints = [NSLayoutConstraint
constraintsWithVisualFormat:@"V:|-50-
[buttonOne(150)]" options:0 metrics:nil
views:NSDictionaryOfVariableBindings(buttonOne)];
[self.view addConstraints:verticalConstraints];
verticalConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:
[buttonTwo(==buttonOne)]-50-|" options:0 metrics:nil
views:NSDictionaryOfVariableBindings(buttonOne, buttonTwo)];
[self.view addConstraints:verticalConstraints];
The bottom button is 50 pixels from the bottom of the view, which is 568
points tall, when the height of self.view should be the screen height
minus the tab bar's height (the navigation bar is hidden). The majority of
this padding is eaten up by the height of the tab bar.
My questions is: Why is my view controller's view not resizing so that it
doesn't count the space under my tab bar as part of its height?

points tall, when the height of self.view should be the screen height
minus the tab bar's height (the navigation bar is hidden). The majority of
this padding is eaten up by the height of the tab bar.
My questions is: Why is my view controller's view not resizing so that it
doesn't count the space under my tab bar as part of its height?

gdb: Cast memory address to an STL object
gdb: Cast memory address to an STL object
I have a memory address that i know is an STL object. Say the address is
0x603340, and I know there is a map there
How do I display the contents of this memory as said object from gdb?
I tried this:
p ('std::map<std::string, std::string*, std::less<std::string>,
std::allocator<std::pair<std::string const, std::string*> > >'*) 0x603340
which gets me:
No symbol "std::map<std::string, std::string*, std::less<std::string>,
std::allocator<std::pair<std::string const, std::string*> > >" in current
context.
Any idea what am I doing wrong? Thanks.

How to replace all capture groups if it is generated dynamically?
How to replace all capture groups if it is generated dynamically?
Consider the following code:
function Matcher(source, search) {
var opts = search.split('');
for (var i = 0; i < opts.length; i++) {
opts[i] = '(' + opts[i] + ')';
}
opts = opts.join('.*');
var regexp = new RegExp(opts, 'gi');
source = source.replace(regexp, function () {
console.log(arguments);
return arguments[1];
});
return source;
}
You call the function passing the source as the first parameter and what
you need to match as the second one.
What i need is to replace all capture groups with a bold tag around the
coincidence.
As an example, consider the following:
var patt =
/m([a-z0-9\-_]*?)r([a-z0-9\-_]*?)i([a-z0-9\-_]*?)e([a-z0-9\-_]*\.[a-z]+)/gi;
var newFileName = fileName.replace(patt,
"<strong>m</strong>$1<strong>r</strong>$2<strong>i</strong>$3<strong>e</strong>$4");
This code is a response from Terry (thanks by the way) but the problem
here is that you need to know exactly what you want to replace, and i need
it dynamically.
Any thoughts?

Restriction of "new" keyword in Javascript
Restriction of "new" keyword in Javascript
I have this JS code:
var A = {};
A.new = function(n) { return new Array(n); }
It works well in all browsers, but when I try to obfuscate it with
obfuscator, it shows an error.
Is it a valid JS code? I looked into specification, but didn't find
anything. I know, that browsers sometimes accept syntactically wrong code,
but I want to write syntactically correct code.

Submit App for iOS 7 Now?
Submit App for iOS 7 Now?
Now that the GM is out, can we send the Binary compiled for iOS 7 only to
the App Store? Or Do we have to wait until September 18?
It seems that Review requires Apps to run iOS 7 now so I'm kinda in a
stump here. It took them 2 weeks to tell me that which is weird because up
to this point iOS 7 was still in Beta. I'm trying to communicate with them
about it though since iOS 6.1.3 is the only official iOS atm. Is this
another waiting game or can I just build against the GM release and try
submitting again?
From my recollection it should be the the Final Build that's allowed to be
submitted, correct?
Thanks!

Looking for master thesis topics in neural networks
Looking for master thesis topics in neural networks
I'm looking for a thesis topic that satisfies the scope of a masters
thesis and is relevant to the current literature in Neural Networks.
I have knowledge inRestricted and Conditional Restricted Boltzmann
Machines, Extreme Learning Machines, Convolutional Neural Networks,
Recurrent Neural Networks, Multi-layer Perceptrons, Sparse Autoencoders,
Deep Belief Nets, and so on
It is difficult to choose one of these topics as they are very interesting
but broad in scope. However, I'm looking for something specific to work
on. To illustrate further my field of interest, I did some work on NLP,
time series, and object recognition research problems.

Checking result of EXPECT_* macros in GTest or run code when ASSERT_* failed
Checking result of EXPECT_* macros in GTest or run code when ASSERT_* failed
I have written C++ tests with GTest which basically work like this
MyData data1 = runTest(inputData);
MyData data2 = loadRegressionData();
compareMyData(data1,data2);
with
void compareMyData(MyData const& data1, MyData const& data2)
{
ASSERT_EQ(data1.count, data2.count);
//pseudo:
foreach element in data1/data2:
EXPECT_EQ(data1.items[i], data2.items[i]);
}
Now I would like to save the data1 contents to a file IFF the test fails
and I don't see an elegant solution yet.
First approach: Make compareMyData return the comparison result. This
can't work with the ASSERT_EQ which is fatal. Writing if (!EXPECT_EQ(...))
doesn't compile so the only way I found is
bool compareMyData(MyData const& data1, MyData const& data2)
{
EXPECT_EQ(data1.count, data2.count);
if (data1.count != data2.count)
return false;
//pseudo:
foreach element in data1/data2:
{
EXPECT_EQ(data1.items[i], data2.items[i]);
if (data1.items[i]!= data2.items[i])
return false;
}
}
Not very elegant :-(
Second idea: Run code when the test failed
I know I can implement ::testing::EmptyTestEventListener and get notified
if a test fails, but that doesn't give me the data I want to write to file
and it is "far away" from the place I'd like it to have. So my question
here is: Is there a way to run code at the end of a test if it failed
(e.g. catching an exception?).
To ask more general: how would you solve this?

Remove Last instance of a character and rest of a string
Remove Last instance of a character and rest of a string
I'm sure this is easy and I know I can use split, pop and join for this.
If I have a string as follows:
foo_bar_one_two_three
Is there a cleaner way w/ regex's to return: foo_bar_one_two?
Thanks

Redirecting Console.WriteLine() to Textbox
Redirecting Console.WriteLine() to Textbox
I'm building this application in Visual Studio 2010 using C#.
Basically there are 2 files, form1.cs (which is the windows form) and
program.cs (where all the logic lies).
//form1.cs
public partial class Form1 : Form
{
//runButton_click function
}
//program.cs
class Program
{
static void Main()
{
while(blah-condition)
{
//some calculation
Console.WriteLine("Progress " + percent + "% completed.");
}
}
}
There is a Run button and a blank textbox.
When the user hits the Run button, program.cs will perform some task and
constantly printing out the progress using Console.WriteLine() onto the
console (command prompt).
Question: How can I print to the textbox on form1 instead of printing into
command prompt? I will need to print the progress constantly without any
user action.
Thanks in advance!
By the way, it doesn't have to be a textbox, it can be a label or
something else that can take text. I chose textbox because it makes more
sense to me.

I am working on android quiz game and dont know how to write code that
save score of every user at the end of game with differnt id on server

prefer to use sqlite database but dont know much about this. If someone
know about this problem plz help me with example of some code.

How to close the ADO connection if the database connection fails while inside a transaction
How to close the ADO connection if the database connection fails while
inside a transaction
I am using ADO via C++, and let's suppose that I have begun a transaction
via ADO when the connection drops out.
I wish to abandon my database changes and close my ADO database connection
object, in order to return to another code module which can display an
error message (without leaving this module in a dodgy state).
The problem is:
1) I cannot close the database connection because the error
adErrInTransaction (0x800a0cae) is thrown (connection object cannot be
explicitly closed while in a transaction)
2) I cannot rollback the transaction because the error 0x8000ffff is
thrown (catastrophic failure, .... connection failure)
This appears to be a catch 22 situation. Had it been that the transaction
was not started then calling Close on the ADO connection succeeds, but
unfortunately with the transaction open I appear to be stuck!
Is the only solution to record the fact that it's failed within a
transaction, so that when the database connection is restored, I can
complete the rollback before attempting anything else?
This was tested with SQLServer 2008 if it's relevant, though I don't
really want a SQLServer-specific solution.

MySQL query based on time range, group users, and sum values over a sliding window
MySQL query based on time range, group users, and sum values over a
sliding window
I want to create a new Table B based on the information from another
existing Table A. I'm wondering if MySQL has the functionality to take
into account a range of time and group column A values then only sum up
the values in a column B based on those groups in column A.
Table A stores logs of events like a journal for users. There can be
multiple events from a single user in a single day. Say hypothetically I'm
keeping track of when my users eat fruit and I want to know how many fruit
they eat in a week (7days) and also how many apples they eat.
So in Table B I want to count for each entry in Table A, the previous 7
day total # of fruit and apples.
EDIT:
I'm sorry I over simplified my given information and didn't thoroughly
think my example.
I'm initially have only Table A. I'm trying to create Table B from a query.
Assume:
User/id can log an entry multiple times in a day.
sum counts should be for id between date and date - 7 days
fruit column stands for the total # of fruit during the 7 day interval (
apples and bananas are both fruit)
The data doesn't only start at 2013-9-5. It can date back 2000 and I want
to use the 7 day sliding window over all the dates between 2000 to 2013.
The sum count is over a sliding window of 7 days
Here's an example:
Table A:
| id | date-time | apples | banana |
---------------------------------------------
| 1 | 2013-9-5 08:00:00 | 1 | 1 |
| 2 | 2013-9-5 09:00:00 | 1 | 0 |
| 1 | 2013-9-5 16:00:00 | 1 | 0 |
| 1 | 2013-9-6 08:00:00 | 0 | 1 |
| 2 | 2013-9-9 08:00:00 | 1 | 1 |
| 1 | 2013-9-11 08:00:00 | 0 | 1 |
| 1 | 2013-9-12 08:00:00 | 0 | 1 |
| 2 | 2013-9-13 08:00:00 | 1 | 1 |
note: user 1 logged 2 entries on 2013-9-5
The result after the query should be Table B.
Table B
| id | date-time | apples | fruit |
--------------------------------------------
| 1 | 2013-9-5 08:00:00 | 1 | 2 |
| 2 | 2013-9-5 09:00:00 | 1 | 1 |
| 1 | 2013-9-5 16:00:00 | 2 | 3 |
| 1 | 2013-9-6 08:00:00 | 2 | 4 |
| 2 | 2013-9-9 08:00:00 | 2 | 3 |
| 1 | 2013-9-11 08:00:00 | 2 | 5 |
| 1 | 2013-9-12 08:00:00 | 0 | 3 |
| 2 | 2013-9-13 08:00:00 | 2 | 4 |
At 2013-9-12 the sliding window moves and only includes 9-6 to 9-12.
That's why id 1 goes from a sum of 2 apples to 0 apples.

| id | date-time | apples | banana |
---------------------------------------------
| 1 | 2013-9-5 08:00:00 | 1 | 1 |
| 2 | 2013-9-5 09:00:00 | 1 | 0 |
| 1 | 2013-9-5 16:00:00 | 1 | 0 |
| 1 | 2013-9-6 08:00:00 | 0 | 1 |
| 2 | 2013-9-9 08:00:00 | 1 | 1 |
| 1 | 2013-9-11 08:00:00 | 0 | 1 |
| 1 | 2013-9-12 08:00:00 | 0 | 1 |
| 2 | 2013-9-13 08:00:00 | 1 | 1 |
note: user 1 logged 2 entries on 2013-9-5
The result after the query should be Table B.
Table B
| id | date-time | apples | fruit |
--------------------------------------------
| 1 | 2013-9-5 08:00:00 | 1 | 2 |
| 2 | 2013-9-5 09:00:00 | 1 | 1 |
| 1 | 2013-9-5 16:00:00 | 2 | 3 |
| 1 | 2013-9-6 08:00:00 | 2 | 4 |
| 2 | 2013-9-9 08:00:00 | 2 | 3 |
| 1 | 2013-9-11 08:00:00 | 2 | 5 |
| 1 | 2013-9-12 08:00:00 | 0 | 3 |
| 2 | 2013-9-13 08:00:00 | 2 | 4 |
At 2013-9-12 the sliding window moves and only includes 9-6 to 9-12.
That's why id 1 goes from a sum of 2 apples to 0 apples.
Javascript Split String at First Numeric

I am trying to split a UK postcode string to only include the initial
letters. For example, 'AA1 2BB' would become 'AA.'
I was thinking something like the below.
var postcode = 'AA1 2BB';
var postcodePrefix = postcode.split([0-9])[0];
This does not actually work, but can someone help me out with the syntax?
Thanks for any help.

TMP = String.format("%-25s %25s", STRING1, STRING2);
Whenever I print TMP, it doesn't seem to properly print the table the way

For example:
STRING1 = Test1 & Test12 STRING2 = Hello
Print:
Test1 Hello
Test12 Hello
Why is that happening?

Unexpected behavior when extracting minima using turnpoints (Pastecs package in R)
Unexpected behavior when extracting minima using turnpoints (Pastecs
package in R)
So I have some data, height.

V3 V4 V5 V6 V7
V8 V9 V10 V11 V12
V13 V14 V15
0.0000000 -3.1486232 39.1502937 -2.8437808 -24.7633269
-35.4022061 -36.2401943 46.4133021 -19.1868097 0.4067331
22.6768200 -38.8550971 -41.3161054
V16 V17 V18 V19 V20
33.0446273 41.4934899 19.9558741 3.3477473 0.3611974
I then apply turnpoints(), and use extract() to get what looks like a
logical vector indicating the positions of the minima.
tp = turnpoints(height)
pitpositions = extract(tp, peak = FALSE, pit = TRUE)
print(pitpositions) # [1] 0 1 0 0 0 0 1 0 1 0 0 0 1 0 0 0 0 0
I would expect that height[pitpositions] would give the values of the
minima, and that height[!pitpositions] would give the values of the
non-minima.
The latter works as expected:
> height[!pitpositions]
V3 V5 V6 V7 V8
V10 V12 V13 V14 V16
V17 V18 V19

V20
0.3611974
But the former doesn't, and I don't know how to interpret the results:
> height[pitpositions]
V3 V3 V3 V3
0 0 0 0
So my questions are:
Why is this happening?
How can I get the result that I'm looking for (basically the opposite of
height[!pitpositions]?
Thanks!

Edit:
To answer question number 2, I can get what I'm looking for using
height[tp$pits]. tp$pits seems to have the same information as
pitpositions, but when I print out pitpositoins I get a series of TRUE
FALSE, whereas when I print out tp$pits I get a series of 0 1. I would
have thought these were equivalent, as 0 == FALSE and 1 == TRUE.
