I got like;
<p>Hello World</p>
And I want to it to be;
<p>Hello <span>World</span></p>
Is this possible by a javascript function? / or jQuery.
Oh yeah, and the p-element got an ID and the text inside the p-element is
variable but always consists of 2 words. I want a span around the last
word of the text by a javascript function.

Sorting a file then storing that into a new file using Python
Sorting a file then storing that into a new file using Python
so I have to sort a file in alphabetical order which isn't my problem. I
can do that, but my problem is writing that sorted list into a new file.
Here is what I have.
import os
os.chdir("/Users/User/Documents") #(I put my name where it says "User")
user_file = open("info.txt", "r")
file = user_file.read()
file_string = file.split("\n")
file_string.sort()
print(file_string) #This is here just so I can see that it sorted correctly
end_file = open("write.txt", "w")
for item in file_string:
end = end_file.write(str(item))
print(end)
Ok, so my info.txt is what needs to be alphabetized and it is just a list
of colors. So my last 4 lines is where I'm struggling. I'm trying to take
each item in the file_string and write those into a new file, but
print(end) gives me how many characters they are. What am I doing wrong?
Thanks

Print a Google Maps API v4 map with polygon
Print a Google Maps API v4 map with polygon
I am trying to print a map I have created with Google Maps API v3. The map
contains a polygon. I am using the pop-up method to try to print it:
var gmapPrint = function() {
var content = window.document.getElementById('map-canvas') // get you
map details
var newWindow = window.open(); // open a new window
newWindow.document.write(content.innerHTML); // write the map into the
new window
newWindow.print(); // print the new window
}
The map prints just fine, but the polygon is missing. At first, it seemed
as though the print dialog was popping up before the polygon was drawn on
the map, so I added a setTimeout. This did not fix the issue. I have also
tried using the static maps API, but the number of points in the boundary
of my polygon exceed the maximum URL size, even when encoded.
Has anyone had any success with this?

Error TF31004 connecting VS2012 to TFS
Error TF31004 connecting VS2012 to TFS
I am trying to setup a new connection to TFS with VS2012. Early on I was
able to add my TFS server and, using the Microsoft Git Provider, clone a
copy of the remote repository from within Visual Studio. Later, as I was
fiddling with things in Team Explorer trying to find the branch I wanted
to use, something broke. My local repository remains, but my connection to
the remote repository was somehow corrupted, as evidenced with this error:
TF31004: Unexpected error encountered while connecting to Team Foundation
Server at http: //my.server.com:8080/tfs. Wait a few minutes and try
again. If the problem persists, contact the server administrator ok help
Things I have tried to resolve this:
Wait and try again (as the error message suggested).
Restart Visual Studio.
Reboot my machine.
Reboot TFS server.
Use system restore to revert back before I installed msysgit and Microsoft
Git Provider, or had attempted to connect to the TFS server.
Review the MSDN help for the error (see below).
Search Stack Overflow (found one other related issue but did not seem to
apply).
The help page offers these tidbits, but none of them seem likely given
that I had, as I said, the connection working at one point:
The version of Team Foundation running on the local computer does not
match the version running on the Team Foundation Server server {name}.
The server returned HTML content instead of XML content.
The required Web service on the server could not be found.
Any ideas would be appreciated!

pick point on parabola so 2 conditions are true
pick point on parabola so 2 conditions are true
You have a parabola y=ax^2+bx+c. We know a,b & c. On this parabola you
have to pick a point A where the following conditions are true:
1) if you draw a tangent line in this point to the parabola, then the
middle point of the following 3 points has to be the midpoint of the other
two points (same distance):
-the point where the parabola touches the tangent line (point A)
-the intersection of the tangent line with the horizontal line drawn
through the vertex: y=(4ac-b^2)/4a.
-the intersection of the tangent line with the axis of symmetry = vertical
line through the vertex: x=-b/2a.
2) Normally, then also for the following 3 points the middle point is on
the same distance to the first and to the third point (all be it on a
different distance as Condition 1, depending on the shape of the
parabola).
-the intersection point of the horizontal line through point A and the
axis of symmetry
-the vertex
-the intersection point of the tangent line to the parabola in point A,
with the axis of symmetry
I know that the slope of the tangent line in a certain Ax will be 2a*Ax+b,
so you can calculate the tangent line through A to be equal to
y=(2aAx+b)(x-Ax)+Ay, but I'm not sure how to move from there to pick point
A so all conditions are still true.
All help is truly appreciated. These things can be pretty frustrating if
you're not mathematically inclined..
In this image, pick point A such that |AF| = |FE| and |ED| =|DB|. I can do
it geometrically, but apparently not algebraically.

Extracting a zip file in my machne givs me CRC error?
I have a large zip that contain hundreds of file. I've unzip'ed it in more
than one machine and didn't have any problem before. However, for this
particular machine (Ubuntu Server 12.04) I keep getting CRC error for some
of the files inside my zip. I've unzip'ed the same file it on anther
machine just to and its fine.
Any clue?

What kind of dock hardware will Ubuntu Touch use?
What kind of dock hardware will Ubuntu Touch use?
We've seen that Ubuntu Touch will be able to be used as a desktop when
docked with a keyboard and mouse. This is an extremely appealing future,
but what I'm wondering is where do you find that kind of hardware? Since
Ubuntu Touch is being designed for Android phones, it would make sense
that such a dock already exists for them, but I haven't seen any. Maybe I
haven't been looking hard enough. Will that be something that is released
after the official launch of Ubuntu Touch?

I have a little problem with jquery toggle function. Sometimes i can fix
it very fast but now im totally crazy about this. Im using jquery transit
plugin to animate a DIV
The code:
$(".grid-1").toggle( function() {
$(this).transition({ perspective: '170px', rotateY: '180deg' },
function() {
$(this).transition({ perspective: '170px', rotateY: '0deg' });
});
});
If i refresh the page this DIV (.grid-1) just disappear... where i make a
mistake ?

try to use if (e.KeyChar == (char)Keys.Enter && e.KeyChar == (char)Keys.N)
- but it's not working. I'm I right - using such code for keys
combination?

c++: vector of vector issue
c++: vector of vector issue
pI wrote a c++ code where i'm testing the running time of vector
push_back. I have a vector of vector. I called my main vector, mainVec,
and embedded vector, subVec. So, I push backed 2^20 elements into subVec
and then push backed subVec 2^20 times into mainVec. However, in the loop
of subVec-push_back I have a cout command which doesn't get executed. I
was hoping you can point out my mistake. /p pHere is the code (There is no
error in the code, though):/p precodevectorlt;intgt; subVec; vectorlt;
vectorlt;intgt; gt; mainVec; //Fills the subvector with 2^20 elements for(
size_t i = 0; i lt; (pow(2,20)+1); ++i) subVec.push_back(i); //Filling of
the maiVec with 2^20 subVec for( size_t j = 10; j lt; 21; ++j) { cout
lt;lt; pow(2,j) lt;lt; endl; clock_t t1 = clock(); //2^j times subVec is
push_backed for j lt; 21 for( size_t k = 0; k lt; pow(2,j); ++k )
mainVec.push_back( subVec ); t1 = clock()-t1; //Outputting to file cout
lt;lt; \t lt;lt; (float(t1) / CLOCKS_PER_SEC) lt;lt; endl; //ofs lt;lt;
pow(2,j) lt;lt; \t\t lt;lt; (float(t1) / CLOCKS_PER_SEC) lt;lt; endl; }

Wrong scope for my nested classes?
Wrong scope for my nested classes?
I'm fairly new to C# and programming in general. At work I monitor a very
large list of servers and websites associated with the application running
on the servers. Generally each application has a cluster of servers behind
it and roughly 6-10 different web-pages. So what I did was I created a
Servers class that will take in a server's name(s) and control the urls
that are associated with it. Now here's the part I'm struggling with. Each
url is going to have two values associated with it: the physical url and
the status of the url (online/offline). I came up with two ways of
handling this: either I create a 2D array (or list) OR create a url
subclass. The subclass method seemed like it would be better since I
thought accessing all the methods of the subclass would be easy... Well
right now I can't call them at all outside of the Servers class. This
makes me think I have an issue with the scope of the classes/methods.
Here's my Servers.cs code... What am I doing wrong?
public class Server
{
public List<string> serverNames = new List<string>();
public List<object> urlList = new List<object>();
public string[][] urlArr = new string[1][];
public Server()
{
}
public Server(string nm)
{
serverNames.Add(nm);
}
public void setName(string newName)
{
serverNames.Add(newName);
}

Server.Url url = new Server.Url(newUrl);

url.SetStatus(false);

how to create exception for char when the input should be int
how to create exception for char when the input should be int
try
{
int selection;
if(selection > 4 || selection < 1)
throw selection;
}
catch(int selection)
{
cout << "Menu selection out of range." << endl;
}
The above code works fine for int values that are out of range, but I
cannot get it to work if a char value is entered at (cin >> selection).
I have tried to post a catch block with an ellipsis [catch(...)] to
account for char entries but that does not work.
I have also tried a catch block with [catch(char selection)] but that does
not work either.
I would like to use an exception to handle this error as it would help in
my overall project in other menu type areas.

add each of these numbers to an array so that I can sort the numbers.

I have tried everything from array_push to call the $_POST['number1']
directly in the array itself. Every time I do echo $numArr all i get is an
empty array as an output.

How does Bootstrap 3 performance compare to Ratchet and Topcoat?
How does Bootstrap 3 performance compare to Ratchet and Topcoat?
I have been developing the prototype of an Android Tablet App using
Cordova(former Phonegap), Angularjs and Twitter Bootstrap 2. It turns out
that the performance of Bootstrap 2 is well known to be poor in embedded
devices. In addition, I noticed that Ratchet and Topcoat are the popular
alternatives, as they take care of the performance themes.
However, I know bootstrap 3 came out with focus on mobile first.
So, how does it compare in terms of performance?

How to retrieve the job and customer suffix field using the quickbooks API
How to retrieve the job and customer suffix field using the quickbooks API
We are building an application that gets data from a QuickBooks online
account using the QuickBooks Online API V2. According to the API
documentation, we can see that the "Suffix" field is supported for both
customer and job tables. However we have noticed this field is not being
returned in the API response. Below is a sample response for a job which
should have a suffix (the suffix is present in the quickbooks UI). Is this
a problem with the API, the API documentation, or our API request?

Access IBOutlet from another ViewController
Access IBOutlet from another ViewController
After read a lot of stuff about delegate concept, and a painfully session
of tests in the last four hours - I began use extern DataModel... to
change data between views in my app.
But for now I really need to access a UIImageView in a ViewController
without NavigationViewController.
As start point I had this question as example:
How do I set up a simple delegate to communicate between two view
controllers?
But I think his content is outdated since the quoted url as example in
wikipedia:
http://en.wikipedia.org/wiki/Delegation_pattern#Objective-C_example have
been excluded.
I'm using Storyboards and I've tried access the IBOutlet with restoration
id, tag id, extern... But with no luck :(
If I have FirstViewController and in SecondViewController I need to access
the UIImageView in the first one, how can I do this?

Exiting an Android app on back button press LibGDX
I have catched my back key and gave Gdx.app.exit();, then the app exits.
Till here its working fine. But, when i happen to a go to a different
screen and get back to my original screen and again press back button, the
app doesn't exit. I would like my app to exit always when I press back
button from a particular screen.
Thanks.

Updating row mapping after external sorting
Updating row mapping after external sorting
I've been using ng-grid (2.0.7) in an AngularJS (1.2.0-rc2) project with
an external search function. My external sort function is working so far,
even the grid data gets updated.
Unfortunately, the rows are keeping their previous order. How can I tell
the grid to update the row order? I don't want to mess around with ng-grid
internals like rowMap and rowCache ...
Thank you in advance for your help!

How can I hide URL from the user while still visiting that page? Or at

How to run script file.exp on php with date-picker parameters?
How to run script file.exp on php with date-picker parameters?
I have made ​​a part of the script but I'm stuck: This code
runs when i select the date from date-picker. I need to run file.exp with
date parameters from date-picker mm dd yyyy. I have a file report.php and
there:
<?
if (isset($_GET['debug'])) { define('DEBUG', true); }
if (isset($_GET['debug_url'])) { define('DEBUG_URL', true); }
if (defined('DEBUG')) header("Content-type: text/plain");
include "lib.php";
$date_to = $date_from = 0;
if (isset($_GET['date-from'])) { $date_from = $_GET['date-from']; }
if (isset($_POST['date-from'])) { $date_from = $_POST['date-from']; }
$date = make_date($date_from) ;
echo "$date_from";
if (preg_match('#^(\d{2})/(\d{2})/(\d{4})$#', $date_from, $matches)) {
$month = $matches[1];
$day = $matches[2];
$year = $matches[3];
} else {
echo 'invalid format';
}
echo "new day: $day";
It works ok i get new day ... but it not work with this command.
$s_command = '/full_path/file.exp
--day'.$day.'--month'.$month.'--year'.$year.'$
echo "$s_command \n";
exec($s_command, $output);
?>
In file.exp i have:
#!/usr/bin/expect -f
foreach {option value} $argv {
switch -glob -- $option {
--day {set day $value}
--month {set month $value}
--year {set year $value}
default { error "Unknown option $option!"
exit 0 }
}
}
Here is the rest of the code and we come to the command:
expect "week ending" { send "$month-$day-$year\r" }
I have to mention that using this file.exp i try to send date mm dd yyyy
to interface on telnet or tty. And also if i put date on static in this
file.exp and run it from command line it works.maybe the problem is this
global-variables(I do not understand them). Please help me :-)

How does this color matrix make image black and white?
How does this color matrix make image black and white?
I am learning about image processing and saw an implementation for how to
turn an image into black and white by changing the color matrix. Below is
the implementation of such a function from Craigs Utility Library:
ColorMatrix TempMatrix = new ColorMatrix();
TempMatrix.Matrix = new float[][]{
new float[] {.3f, .3f, .3f, 0, 0},
new float[] {.59f, .59f, .59f, 0, 0},
new float[] {.11f, .11f, .11f, 0, 0},
new float[] {0, 0, 0, 1, 0},
new float[] {0, 0, 0, 0, 1}
};
Bitmap NewBitmap = TempMatrix.Apply(Image);
I know from this article that the matrix represents RGBAW (red green blue
amber and white). So, from my understanding, the colormatrix is
multiplying each of the RGB colors with the array {.3f, .59f, .11f}.
However I believe I am missing the last step.
Where do the constants .3f, .59f, and .11f come from that make an image
black and white? How does this matrix multiplication make the image black
and white?

Unsupported major.minor version 51.0 Error With Eclipse When Trying to Reference Jar File
Unsupported major.minor version 51.0 Error With Eclipse When Trying to
Reference Jar File
I have a simple java sandbox project which I reference the code for
Xerces-For-Android. If I put the source code directly into the project,
I'm able to compile and run my test program successfully. However if I
make a jar file, then add that into my build path I get the Unsupported
major.minor version 51.0.
Reading several posts, the Unsupported major.minor version 51.0 seems like
it is an issue based on compilation of different java versions. The
version 51.0 looks to be java 7. To simply my testing, I uninstalled all
Java 7 installs from my machine, ensured that my eclipse projects point to
the same Java 6 JRE, and that my JAVA_HOME is set to Java 6u45. I also
restart eclipse to make sure my changes were in place.
I'm using Ant to create the jar file. The code is very simple and I even
specify the javac target to be 1.6.

How do I color labels for my pie chart in D3?
How do I color labels for my pie chart in D3?
I started out with the following example:
http://jsfiddle.net/nrabinowitz/GQDUS/
I am trying to get the labels for each arc to be the color of the arc.
I have gotten it to where it colors all the labels the same color. But I
do now know how to access each individual label and change the color.
In my code I have done the following for the last line:
arcs.append("svg:text").attr("transform", function (d){var c =
arc.centroid(d); x = c[0]; y = c[1]; h = Math.sqrt(x*x + y*y);
return "translate(" + (x/h * 100) + ',' + (y/h * 90) +
")";}).text(function(d){return
Math.round((d.data/total)*100)+"%";}).attr("text-anchor","middle").attr("fill","color_data.pop()");
This makes all the labels the first color in my array. However I need each
label to be a different color in the array. I am just not sure how to
access the labels so I can loop through and change the color.

Validate user input for file_get_contents PHP
Validate user input for file_get_contents PHP
In my php file I use a $_GET parameter to open a file on my server, like so:
$filename = $_GET["filename"];
$content = file_get_contents("/path_to_files/".$filename);
My question is, how do I make this more secure so the user cannot access
files in parent folders on the server? Is this something I need to do on
the server such as permissions and/or configurations? Or should $filename
be validated in my php file? Thanks in advance!

valid and you click on submit the page reloads and the inputs are placed
in the url address bar (i.e. method="get")
In the ajax method I have that set to POST but it doesn't appear to be
using the ajax call.
What did I do wrong?
$().ready(function() {
var $form = $(this);
//validate the inquiry form on keyup and submit
$("#inquiryForm").validate({
showErrors: function(errorMap, errorList)
{
for (var error in errorMap)
{
$.growl.error({ message: errorMap[error] });
}
},
onkeyup: false,
rules: {
fullName: {
required: true
},
email: {
required: true,
email: true
},
inquiry: {
required: true,
minlength: 5,
maxlength: 500
}
},
messages: {
fullName: "Your name is required",
email: "A valid email address is required",
inquiry: "Your inquiry is required and must have
between 5-500 characters"
},
submitHandler: function(form) {
$.ajax({
url: form_submit/inquiry_form/inquiry_form.php,
type: "POST",
data: $(form).serialize(),
success: function(response) {
$('#inquiryFormHolder').html("Your form was
submitted!");
}
});
return false;
}
});
});

MEMORY LEAK
Trying to dynamically implement an array in C++ with the following function.
I am not sure if the newArray needs to be deleted but right now it gives a
memleak.

newArray[i] = dynamicArray[i]; // Copy over old data
}
// Update private variables
delete [] dynamicArray; // Remove the old array (prevent
memory leak)
dynamicArray = newArray;

select-all checkbox in a jquery data table with column filter
select-all checkbox in a jquery data table with column filter
Does anyone know how to add a checkbox in the column-filter plugin header
of a jquery datatable? and when I check the checkbox, to trigger a
callback (where I will 'check' all the checkboxes in the table or
'uncheck', if case)?
And no, I am not talking about this:
http://jquery-datatables-column-filter.googlecode.com/svn/trunk/checkbox.html.
I just need a plain old simple checkbox, not that rich-checkboxed
dropdown. Something like on yahoo-mail - if you want an example.
In case it matters: + jquery-version: 1.8.3 + jquery.dataTables version:
1.9.4 + jquery.dataTables.columnFilter: 1.4.5

Avoiding SingleOrDefault null reference exception
Avoiding SingleOrDefault null reference exception
I'm adding parameters to insert information into a database and ran into a
a potential null reference exception. By using the SingleOrDefault LINQ
expression, I thought if an instance had no Tag called "Name" the Tag
would default to a null value. This is true as long as the instance has
some sort of Tag. If the instance has no tags at all, a null reference
exception occurs. It's a rare occurrence, but I still need a better way to
handle it. Is there a better way to solve this than catching the
exception?
cmd.Parameters.AddWithValue("@Name", runningInstance.Tag.SingleOrDefault(t
=> t.Key == "Name").Value);

How to accelarate insert into database in java?
I need insert many rows from many files like:
Identifier NumberValue
For each row I am looing if already exists in database row with
Identifier, if exists I will take its NumberValue and add NumberValue from
arriving row and update database. I have found that lookup in database for
each row (few millions of records total) takes many time. Does it make
sense create map and look before inserting in database in this map?
Thanks.

How to disable UserProfile table access with ASP.NET MVC4 custom membership
How to disable UserProfile table access with ASP.NET MVC4 custom membership
I am trying to use ASP.NET MVC4, while keeping the user data in NoSQL data
store.
I am implementing my own membership class, supporting both OAuth and forms
authentication, inherited from ExtendedMembershipProvider.
At some point, I noticed that the local data store 'UserProfile' table is
being filled out with OAuth users. Seems like the default generated code
in AccountController::ExternalLoginConfirmation is manipulating that table
directly.
I found an article on implementing a custom Profile Provider.
Yet this seems a huge overkill to my needs, since I can manage user
profile in the application.
Is there a clean way to disable to "Profile" feature? Is it legitimate to
edit the controller code, or it is rather hiding the real problem? If I
must have the "ProfileProvider" on my own, what is the mininal set of
methods I can implement to get it "happy"?
Thanks a lot.

No Database Selected JPA Persistence
No Database Selected JPA Persistence
I have connections to my database running. I can execute the following

However, after setting up JPA and a persistant class, I always get a "No

when a program is trying to add WordBlock (which is my class extending
UserControl) to StackPanel's content in DoSend method, it sometimes
(actually quite often, especially when query returns more than one result)
throws an ArgumentException, it surely has something to do with Threading
(SearchThreadEngine is a method running in in second thread), but I am
weak in the topic, and don't know why it is happenig. So, I will gladly
accept any help. Here's a stack trace:

Partial call back from Ajax Extender Calender date changes
Partial call back from Ajax Extender Calender date changes
I am using the ajaxToolkit:CalendarExtender control. I want to call a
server method after the date has changed. I am currently using:
OnClientDateSelectionChanged="function
ddd(){__doPostBack('DateTextBox','') ;}"
This will do a partial post back in IE but in Chrome it will do a full
post back. I have thought of calling a jquery method for the
OnClientDateSelectionChanged event. I have failed on an .Ajax call but on
a Post back call it does a partial callback. But, i do not get a chance to
select a date. Using this jquery bypasses the chance to select a date. Any
advice would be great.
thanks

UISearchDisplayController in DetailView only displays results once
UISearchDisplayController in DetailView only displays results once
I implemented a UISearchDisplayController on both sides of a
MasterViewController. In the Detail view, it works fine with the first
item selected from the MasterView.
However, if I choose another Detail item, the search will not display any
object even though NSLog tells me it found all of the expected cells:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *feedTableIdentifier = @"unread";
Post *thepost=nil;
if (tableView ==
self.searchDisplayController.searchResultsTableView) {
NSLog(@"in a search");
thepost = [self.filteredFeedArray objectAtIndex:indexPath.row];
} else {
NSLog(@"NOT in a search");
thepost = [self.fetchedResultsController
objectAtIndexPath:indexPath];
}
NSDate *tmpDate=[NSDate date];
if (thepost.read) {
tmpDate=thepost.read;
feedTableIdentifier = @"read";
} else if (thepost.date) {
tmpDate=thepost.date;
feedTableIdentifier = @"unread";
}
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:feedTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:feedTableIdentifier];
}
((UILabel *)[cell viewWithTag:1]).text = thepost.title;
NSDateFormatter *df=[[NSDateFormatter alloc] init];
df.dateFormat = @"EEEE, MMMM d, YYYY";
((UILabel *)[cell viewWithTag:2]).text = [df stringFromDate:tmpDate];
((UILabel *)[cell viewWithTag:3]).text = [self
flattenHTML:thepost.excerpt];
return cell;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
if (tableView ==
self.searchDisplayController.searchResultsTableView) {
NSLog(@"in a search: %d", [_filteredFeedArray count]);
return [_filteredFeedArray count];
} else {
NSLog(@"NOT in a search: %d", [[[_fetchedResultsController
sections] objectAtIndex:section] numberOfObjects]);
return [[[_fetchedResultsController sections]
objectAtIndex:section] numberOfObjects];
}
}
Both detail and searchresult Table view have samely named Prototype cells.
Can someone tell me what I am doing wrong here and how I could properly
reset my UISearchViewController whenever switching Detail items?

How do you program time?
How do you program time?
This might sound like a weird question, but how can you program time
without using the API of a programming language? Time is such an abstract
concept, how can you write a program without using the predefined function
for time.
I was thinking it would have to be calculated by a count of processor
computations, but if every computer has a different speed performance how
would you write code to iterate time.
Assuming the language the program is written in doesn't matter, how would
you do this?

Python socket not sending host name
Python socket not sending host name
I am using an asyncore.dispatcher client on python to connect to a server
developed in C running on a PC. Here's the code snippet on the client that
connects to the server:
class DETClient(asyncore.dispatcher):
def __init__(self, host, port):
asyncore.dispatcher.__init__(self)
self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
self.connect((self.host,self.port))
On the server side, my C code is looking for two parameters, TCPPeerName
and TCPPeerAddr.
It seems that the python code is not passing the hostname at all, because
my server gets a NULL for PeerName.
Do I have to do anything to specifically make the asyncore client to send
the PeerName when establishing a connection?

Strange JavaScript collapse behaviour in VS2012
Strange JavaScript collapse behaviour in VS2012
Visual Studio 2012 offers me the possibility to collapse this function
(see the little "-" icon on the left).
Sometimes he arbitrarely decide I can't do that.
Can someone explain why and how to fix it? I want to collapse every
function in my code: can I do this? How?
It looks like placing $.get, $('selector') or $.each calls in my code is
causing the issue but, since it mostly looks like a random behaviour, I
can't tell for sure.
Here's some random piece of code which is causing the issue:
function ComputeHigherZIndex() {
var highest = null;
$('#@(mdi.ContainerDivId)').find('.dynawindow').each(function () {
var current = $(this).css("z-index");
if (highest == null || highest < current) {
highest = current;
}
});
return highest;

(see the little "-" icon on the left).
Sometimes he arbitrarely decide I can't do that.
Can someone explain why and how to fix it? I want to collapse every
function in my code: can I do this? How?
It looks like placing $.get, $('selector') or $.each calls in my code is
causing the issue but, since it mostly looks like a random behaviour, I
can't tell for sure.
Here's some random piece of code which is causing the issue:
function ComputeHigherZIndex() {
var highest = null;
$('#@(mdi.ContainerDivId)').find('.dynawindow').each(function () {
var current = $(this).css("z-index");
if (highest == null || highest < current) {
highest = current;
}
});
return highest;
}

Issue with # in URL with a Wordpress theme?
Issue with # in URL with a Wordpress theme?
I am having a severe problem and have no clue about what is going on... I
will specify the general issue which is causing multiple issues on this
Wordpress powered portal.
Steps to reproduce:
Visit the URL: http://gamersgeographic.com/en/ (or any post on this site)
Append #abc or #anything to the URL
The URL tries to resolve for a second and magically deletes the "#" and
instead changes to /abc or /anything , which of course does not exist and
gives a 404 page not found.
Even if the local anchor with #abc exists, behaviour is the same.
Now, consider the case below:
Visit http://gamersgeographic.com/monster-hunter-diary-1/
Comment link appends a #comments or #respond depending on whether a
comment is there or not.
Both the anchors exist on the single post page
Still it redirects after finding them, to /comments and gives 404
Direct URL with #comments works e.g.
http://gamersgeographic.com/monster-hunter-diary-1/#comments works but
when I change any base URL to #comments, it redirects to 404...
I have tried several combinations with Permalinks, so it is not a problem
with that. I even wrote my own Comment link generator in php with just a
plain href="#comments"
but still no luck...
If you need any further information about any function's code in
theloop.php or anything please let me know.
Thanks in advance ! Regards

Event Driven programming - non linear code
Event Driven programming - non linear code
I have the following code (logic) in PHP:
$fp = fopen('fp.txt', 'w');
if ($msg == 'say') {
fwrite($fp, 'Hello world!');
}
$msg = 'done';
To convert this into asynchronous event driven code, the author of node
for PHP developers suggests I refactor it like this.
$fp = fopen('fp.txt', 'w');
if ($msg == 'say') {
fwrite($fp, 'Hello world!');
$msg = 'done';
} else {
$msg = 'done';
}
And then,
fs.open('fp.txt', 'w', 0666, function(error, fp) {
if (msg == 'say') {
fs.write(fp, 'Hello world!', null, 'utf-8', function() {
msg = 'done';
});
} else {
msg = 'done';
}
});
You'd clearly see, there is code duplication. 'msg = "done"' is repeated.
Can this be avoided? Code duplication is bad practice right?
Is event driven programming always like this?

Putting Results of for loop into a data frame in R
Putting Results of for loop into a data frame in R
I have a function that will return a numeric class object, here is a
simplified version:
count.matches <- function(x) {
ifelse(!is.na(a[,x] & a[,2]),1,0)
}
it just produces an object of 0s and 1s. For example
count.matches(4)
[1] 0 0 0 0 1 1 0
I just want to do a simple for loop of this function and store the results
in a data frame, i.e. each time the function loops through create a
column, however I am having trouble.
p <- data.frame()
my.matches <- for(i in 2:100) {
p[i,] <- count.matches(i)
}
This produces nothing. Sorry if this is a really stupid question, but I
have tried a bunch of things and nothing seems to work. If you need any
more information, please let me know and I will provide it.

I am trying to decipher the following line of JavaScript code:

Specifically the ? followed by the !. Is that a comparison operator?

Extracting TTL value for an A record
Extracting TTL value for an A record
I am doing some dns stuff and I require to do an A record lookup for an
SRV and extract ttl and ip address from it:
I was able to extract ip using the following code, but how do I extract TTL?
l = res_query(argv[1], ns_c_any, ns_t_a, nsbuf, sizeof(nsbuf));
if (l < 0)
{
perror(argv[1]);
}
ns_initparse(nsbuf, l, &msg);
l = ns_msg_count(msg, ns_s_an);
for (i = 0; i < l; i++)
{
ns_parserr(&msg, ns_s_an, 0, &rr);
ns_sprintrr(&msg, &rr, NULL, NULL, dispbuf, sizeof(dispbuf));
printf("\t%s \n", dispbuf);
inet_ntop(AF_INET, ns_rr_rdata(rr), debuf, sizeof(debuf));
printf("\t%s \n", debuf);

How do I perform this regex in order to extract the value of the variable
How do I perform this regex in order to extract the value of the variable
You can test everything out here:
I would like to extract the value of individual variables paying attention
to the different ways they have been defined. For example, for dtime we
want to extract 0.004. It also has to be able to interpret exponential
numbers, like for example for variable vis it should extract 10e-6.
The problem is that each variable has its own number of white spaces
between the variable name and the equal sign (i dont have control on how
they have been coded)
Text to test:
dtime = 0.004D0
case = 0
newrun = 1
periodic = 0
iscalar = 1
ieddy = 1
mg_level = 5
nstep = 20000
vis = 10e-6
ak = 10e-6
g = 9.81D0
To extract dtime's value this REGEX works:
(?<=dtime =\s)[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?
To extract dtime's value this REGEX works:
(?<=vis =\s)[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?
The problem is that I need to know the exact number of spaces between the
variable name and the equal sign. I tried using \s+ but it does not work,
why?
(?<=dtime\s+=\s)[-+]?[0-9]*\.?[0-9]+([eE][-+]?[0-9]+)?

How to debug selenium webdriver through eclipse using maven and junit
How to debug selenium webdriver through eclipse using maven and junit
I have a bunch of selenium webdriver tests in eclipse. How can I run them
in debug mode through eclipse so I can properly debug them instead of just
outputting stuff to the log?
When I run the tests I use the following command line: mvn -Dtest=testName
test -Dconf=MyPropertis.properties
but I don't know how to do this through eclipse.

iOS 7: Misplaced View Frame for "Label - Label" will be different at run time
I just finished an app on iOS 6 and bought a developer account a week ago
so haven't had much time playing with the iOS 7 SDK. Just downloaded the
Golden Master version and trying to upgrade my app to be compatible with
iOS 7.
I received a lot of warnings saying "Misplaced View Frame for "Label -
Label" will be different at run time." and i am unable to run the program.
The project contains tableview and its is parsing and displaying xml feed
from an rss.
Anyone knows how to fix this issue? Thanks a lot in advance!

How do I center a container in my HTML/CSS?
How do I center a container in my HTML/CSS?
I have developed a website as part of my assignment. As I am new to
html/css I could not figure some problems out of my code. The assignment
specifications says that the screen size should be in certain size so that
majority browsers can open it and the user should not experience any
scroll activties. So I have used div to divide the whole page to fit the
size. However, the container(In my code named as 'box') is set to the left
side of the brower body and I have to set it centred, but I do not know
how to fix it. Can anyone give me some help, please and thank you.

Switch statement inside a foreach loop - not getting expected results
Switch statement inside a foreach loop - not getting expected results
So I am trying to loop though items that are in a listbox in my
application. The list box will allow you to select multiple items to which
I have a method tied to each item in the listbox. I have a counter
variable incremented each time the loop works.When I use the foreach loop
with the switch statement below, it does the first item correct, but then
loops through the same item again. I know I am missing something as it is
supposed to go to the next item in the listbox and not the same item.
string reportname = lstbxReports.SelectedValue.ToString();
int i = 0;
foreach (var report in reportname)
{
switch (reportname)
{
case "Overview":
{
if (i < 1)
{
PrintOverview(filename);
}
else if (i >= 1)
{
PrintOverviewAppend(filename);
}
break;
}
case "Sources":
{
if (i < 1)
{
PrintSource(filename);
}
else if (i >= 1)
{
PrintSourceAppend(filename);
}
break;
}
}
i++
Any thoughts or suggestions on how I can get the foreach loop to go to the
next item in the selected listbox?
Also, this is just a snippet as I have about 11 case items to loop through.
