I am attempting to create a function which generates a CSV type file for use in excel by exporting data from a table in MySQL. So far I have got everything working except that I would like to substitute one of the variables in my table from 'Client ID' (a number) to 'Company Name' (a text value) so it makes the final exported file easier to read.

In [this FAQ question][1] it says that compression is used automatically when the browser supports it and that I don't need to modify my application in any way.
My question is, **does that apply to Channel API messages too?**
I have an application that needs to send relatively large JSON (text) data through a persistent connection and I'm hoping I can get things through faster if they are compressed.
If not, I can think of a workaround to have the server send just a ping through the channel when a big load comes through and have the browser then make a GET request to fetch it (and that would "automatically" compress it), but that would add the latency of another request.

I have source array, and I want to generate new array from the source array by removing a specified number of elements from the source array, I want the elements in the new array to cover as much as possible elements from the source array (the new elements are uniformly distributed over the source array) and keeping the first and last elements the same (if any).
I tried this :

{

for (int i = 1; i < inputArr.length ; i++)
{

{
System.out.println("i=" + i + " j= " + j);

{

a = removeElements(a, 6);
printArr(a);
}
I have made a test for(removeElements(a, 5) and removeElements(a, 4) and removeElements(a, 3)) but removeElements(a, 6); gave :
arr[0]=1.0
arr[1]=3.0

arr[4]=9.0
arr[5]=11.0
arr[6]=13.0
arr[7]=15.0

the problem is (arr[8]=0.0) it must take a value ..
How to solve this? is there any code that can remove a specified number of elements (and keep the elements distributed over the source array without generating zero in some elements)?

Threads T1 & T2 receive data from socket & add the object to the specific Q's for c1 to c200.
Infinite loop inside the run(), which calls LinkedBlockingDeque.take()
In the load run the CPU usage for the javae.exe itself is 40%. When we sum up the other process in the system the overall CPU usage reaches 90%.
By using JavaVisualVM the run() is taking more CPU and we suspect the LinkedBlockingDeque.take()
So tried alternatives like thread.wait and notify and thread.sleep(0) but no change.
The reason why each thread c1 to c200 having separate Q is for two reason,
1.there might be multiple request for c1 from T1 or T2
2.if we dump all req in single q, the seach time for c1 to c200 will be more and search criteria will extend.

After that I tried phpMyAdmin and there I found out that my csv was too big. I've split it in 5 using CSV Splitter. I've made the import for the first file. Everything went great. Than I tried to import the second one, but I got thos error:

I working on a website and i'm a bit stucked with the following problem and i hope that somebody can give me some help with it.
The website is http://www.clothesmakemen.com/Nieuwewebsite/casual.html
When you click on a thumbitem on the right the item loads with ajax without reloading the whole page, this is great. The problem is that the thumbitems disapear and i need them to be there. So i need some script that after clicking on a thumbitem the item loads without losing the thumbs on the right :)
Hope you guys can understand what i mean :D

One way I thought of doing it was to insert all the images into divs, and hiding all those divs, and one by one unhiding those divs and sliding them in.

The error from the emulator is "Unfortunately, appname has stopped". It was working fine, until I wrote a bunch of new code, and changed the manifest. Hopefully it's not the manifest, but my question is, how can I find out what line of code is the problem? The trace dump means nothing to me, and even though it's verbose, having ...11 more doesn't let me see the whole thing.
I don't really know what that error means. I've searched for it, but there seems to be a list of things it could mean. I've tried Project>Clean, I've tried messing with the manifest again, but I still get the error. I've checked/unchecked external libraries. Just done what people have suggested to do for other people getting the same error. So I'd really like to know, what line set it off?
Here is the output if this helps:

| android | error-handling | android-emulator | null | null | null | open | Android: How to get the specific line of code that threw an error
===
I'm getting a java.lang.NullPointerException right when the app launches and it shuts down. The error from the emulator is "Unfortunately, appname has stopped". It was working fine, until I wrote a bunch of new code, and changed the manifest. Hopefully it's not the manifest, but my question is, how can I find out what line of code is the problem? The trace dump means nothing to me, and even though it's verbose, having ...11 more doesn't let me see the whole thing.
I don't really know what that error means. I've searched for it, but there seems to be a list of things it could mean. I've tried Project>Clean, I've tried messing with the manifest again, but I still get the error. I've checked/unchecked external libraries. Just done what people have suggested to do for other people getting the same error. So I'd really like to know, what line set it off?
Here is the output if this helps:

- WCF application hosted on IIS7
- Basic HTTP binding - SecurityMode = TransportCredentialOnly and ClientCredentialType = Windows.
- .Net 4.0
- The app runs in a .Net 4.0 Application Pool using "ApplicationPoolIdentity".
- IIS connects to the file system using "Application Pass Through" authentication.
- The client and service both run under IIS - that is the client is a webste and the service is an IIS hosted WCF service.
What I would like to understand is that what user accounts are used at the various points in authenticating too and using the service.
- I understand that ApplicationPoolIdentity is a built in Windows account that is generated for each created application pool - is this the account under which w3wp.exe will run for the website?
- No credentials are specified between clent and server - and this is the most interesting point. When my client connects to my WCF application what identity is used to authenticate to the service. I presume the application pool identity of the app pool hosting client website?
- If so then what would happen if the two sites use two differnet app pools?
- Or does the service just require a valid account on the machine (or domain) and that is good enough to authenticate?
- If I changed the application pool to use a specific user account does this change anything? Again I presume as long as the client passes a valid machine account is that ok?
Also,,,
- What identity is used for the file system?
- What permissions does "ApplicationPoolIdentity" have on the machine and for the file system.
- Finally in the case of SQL Server Integrated security what identity is passed through to SQL server if my service talks to an SQL Server database.
Thanks in advance.

My java source files are encoded in UTF-8.
If I define my literal strings like this :
new Language("fr", "Français"),
new Language("zh", "中文")
It works as I expect when I use the string in the application by launching it from Eclipse as a RAP application :
![enter image description here][1]
But if fails when I launch the .exe built by the "Eclipse Product Export Wizard" :
![enter image description here][2]
The solution I use is to escape the chars like this :
new Language("fr", "Fran\u00e7ais"), // Français
new Language("zh", "\u4e2d\u6587") // 中文
There is no problem in doing this (all my other strings are in properties files, only the languages names are hardcoded) but I'd like to understand.
I thought the compiler had to convert the java literal strings when building [the bytecode](http://en.wikipedia.org/wiki/Java_class_file#The_constant_pool). So why is the unicode escaping necessary ? Is it wrong to use use high range unicode chars in java source files ? What happens exactly to those chars at compilation and in what it is different from the handling of escaped chars ?

The form works only with the `<input type="hidden" value="list" name="seek_stud">`. Could someone please explain me why is this line necessary(what does it actually do)? Because I found on Google that [B]hidden[/B] is used only when you submit some information(not visible to the user) in addition to what the user types, and I am not sending such additional information. :confused:
Thank you in advance! | 0 |

I'm using Blender version : 2.63a
Got Lamarche's script from here : https://github.com/jlamarche/iOS-OpenGLES-Stuff
What I did
- Installed the script as it is described in instructions
- Opened blender with default cube
- Tried to export Objective C header file of the default 3D
The header file is generated without any vertex data, any idea why this happens ?
Please provide any reference that might help me to load 3D model into iOS GL context with its texture.

Basically some function calls Bisection2 and this function calls either the passed function or it passes the function pointer to Bisection function.
in header I have
std::vector<double> F();
double F1(double m1, double m2);
double F2(double m1, double m2);
typedef double (MyClass::*MyClassFn)(double,double);
double Bisection(MyClassFn fEval,double min, double max,std::vector<double> args);
bool Bisection2(MyClassFn fEval1,MyClassFn fEval2,double xmin, double xmax, double ymin, double ymax,double *ax, double *ay,std::vector<double> args);
And my bisection functions look like this. I didn't include all the code because it's not necessary.
double MyClass::F1(double m1, double m2) {
m_m1 = m1;
m_m2 = m2;
F();
return m_my;
}
double MyClass::F2(double m1, double m2) {
m_m1 = m1;
m_m2 = m2;
F();
return m_mx;
}
double MyClass::Bisection(MyClass fEval,double min, double max,std::vector<double> args)
{
// Setting a lot of stuff here, including auxiliary and leftvalue...
MyClass *pObj = new MyClass(-1);
leftvalue = pObj->*fEval(auxiliary, left);
ightvalue = pObj->*fEval(auxiliary, right);
// Comparing and setting values here etc.
}
bool MyClass::Bisection2(MyClassFn fEval1,MyClassFn fEval2,double xmin, double xmax, double ymin, double ymax,double *ax, double *ay,std::vector<double> args)
{
// Setting some values here but these have nothing to do with the problem.
double yl;
double leftvalue, rightvalue, middlevalue;
MyClass *pObj = new MyClass(-1);
// Setting some values here but these have nothing to do with the problem.
std::vector <double> arg;
// pushing some values
yl = Bisection(fEval2,ymin,ymax,arg); // Here is the first way how I need to pass fEval2 to Bisection function.
arg.clear();
if(isnan(yl))
{
return M_NAN;
}
leftvalue = pObj->fEval1(xl, yl); // And here is the second way how I need to use fEval1.
//.....
}
And then I have basically a function what calls
`Bisection2(F1,F2, m_m2,0.0, 0.0, m_max2, &m_mu1, &m_mu2,args);
The Bisection2(...) call may be incorrect at the moment because I've changed the functions a lot since this worked last time. Last time I basically called F1 and F2 function pointers directly inside the functions instead of fEval's but I'm quite sure it was incorrect way after all even thought it seemed to work somehow.
Now leftvalue = pObj->*fEval(auxiliary, left); causes compiling errors:
error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘fEval (...)’, e.g. ‘(... ->* fEval) (...)’

My situation is following, I have two different bisection functions what will be called at some point in my code. Basically some function calls Bisection2 and this function calls either the passed function or it passes the function pointer to Bisection function.
in header I have
std::vector<double> F();
double F1(double m1, double m2);
double F2(double m1, double m2);
typedef double (MyClass::*MyClassFn)(double,double);
double Bisection(MyClassFn fEval,double min, double max,std::vector<double> args);
bool Bisection2(MyClassFn fEval1,MyClassFn fEval2,double xmin, double xmax, double ymin, double ymax,double *ax, double *ay,std::vector<double> args);
And my bisection functions look like this. I didn't include all the code because it's not necessary.
double MyClass::F1(double m1, double m2) {
m_m1 = m1;
m_m2 = m2;
F();
return m_my;
}
double MyClass::F2(double m1, double m2) {
m_m1 = m1;
m_m2 = m2;
F();
return m_mx;
}
double MyClass::Bisection(MyClass fEval,double min, double max,std::vector<double> args)
{
// Setting a lot of stuff here, including auxiliary and leftvalue...
MyClass *pObj = new MyClass(-1);
leftvalue = pObj->*fEval(auxiliary, left);
ightvalue = pObj->*fEval(auxiliary, right);
// Comparing and setting values here etc.
}
bool MyClass::Bisection2(MyClassFn fEval1,MyClassFn fEval2,double xmin, double xmax, double ymin, double ymax,double *ax, double *ay,std::vector<double> args)
{
// Setting some values here but these have nothing to do with the problem.
double yl;
double leftvalue, rightvalue, middlevalue;
MyClass *pObj = new MyClass(-1);
// Setting some values here but these have nothing to do with the problem.
std::vector <double> arg;
// pushing some values
yl = Bisection(fEval2,ymin,ymax,arg); // Here is the first way how I need to pass fEval2 to Bisection function.
arg.clear();
if(isnan(yl))
{
return M_NAN;
}
leftvalue = pObj->fEval1(xl, yl); // And here is the second way how I need to use fEval1.
//.....
}
And then I have basically a function what calls
`Bisection2(F1,F2, m_m2,0.0, 0.0, m_max2, &m_mu1, &m_mu2,args);
The Bisection2(...) call may be incorrect at the moment because I've changed the functions a lot since this worked last time. Last time I basically called F1 and F2 function pointers directly inside the functions instead of fEval's but I'm quite sure it was incorrect way after all even thought it seemed to work somehow.
Now leftvalue = pObj->*fEval(auxiliary, left); causes compiling errors:
error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘fEval (...)’, e.g. ‘(... ->* fEval) (...)’
I've tried to see help from here [http://www.parashift.com/c++-faq-lite/pointers-to-members.html#faq-33.2][1]
and also checked maybe different solved problems in these forums but still can't figure out what I'm doing wrong.
Thank you.

I am using FLARToolkit and it works fine, except the frame rate drops to ridiculous lows in certain lighting conditions. This is because Flash only uses the CPU for processing, and every frame it is applying filters, adjusting thresholds, and analyzing the pixels to find the marker pattern. Without any hardware acceleration, it can get really slow.
I did some searching and it looks like the fastest and most stable tracking library is Studierstube ( http://handheldar.icg.tugraz.at/stbtracker.php and http://studierstube.icg.tugraz.at/download.php ). Unfortunately, I am not a C++ developer. But it seems that the tracking is insanely fast using this tracker (especially since it isn't all CPU processing like Flash is).
So my plan is to build (or rather have someone build) a small C++ program that leverages this tracker, and then sends the marker position data every frame (only need 30 FPS) to my Flash client application to display back the video and some augmented reality experiences. I believe this would be done through a socket server or something right? Is this possible and fairly easy for someone who is a decent C++ developer? I would ask him/her but I am in search for such a person. | c++ | actionscript-3 | air | augmented-reality | socketserver | null | open | C++ socket server to Flash/Adobe AIR?

A few of us running either Mac OS X Snow Leopard or Lion and installing the FlashBuilder 4.6 eclipse plug-in are experiencing an issue where the plug-in simply does not show up in Eclipse. The installation adds a file under the <eclipse_installation>/dropins directory called **fb-4_6-plugin-encoded.link** that is supposed to tell Eclipse the location of the Adobe FlashBuilder installation.
The scenarios we have encountered are as follows:
- Installation works without any problems and the plug-in is registered.
- Plug-in is registered, but does not show up. Running Eclipse with `-consoleLog` shows no errors.
- Eclipse running with the -consoleLog switch says that the **fb-4_6-plugin-encoded.link** file is not accessible. Doing a `chmod 777` on the file fixes the issue and the plug-in is registered.
Here are the notes from the **README** that comes with FlashBuilder:
----------
> Flash Builder 4.6 supports installation as a plugin to an existing
> Eclipse instance.
> To do so:
> 1. Complete the installation process as described above.
> 2. Navigate to the installed Flash Builder installation location and open the utilities folder.
> 3. Run the executable Adobe Flash Builder 4.6 Plug-in Utility.app.
> 4. Select the language and click on OK.
> 5. Select the Flash Builder installation location if prompted.
> 6. Select the eclipse folder into which you want Flash Builder 4.6 to be plugged into and click Next. (Note: Your copy of Eclipse must be
> version 3.6/3.6.1/3.6.2/3.7, 32-bit, Cocoa, containing a folder named
> “dropins”).
> 7. Review the pre-Installation summary and click on Install.
> 8. Following installation it is recommended that you edit the eclipse.ini file for your Eclipse instance, so that it includes the
> following settings:
> -vmargs -Xms256m -Xmx512m -XX:MaxPermSize=256m -XX:PermSize=64m
----------
**Questions**
Is there any Eclipse magic that can be performed to further investigate the issue? Is there any way to manually register the FlashBuilder plug-in (or generally a dropins style plug-in)?

The $_REQUEST contains the history:

As an side issue, how can I ensure that the correct radio buttons are re-checked at data re-entry.
Advice and help, please.
Thanks

Here's how I `insert` an instance of `B` into the `map`:
{
cout << "-- 1\n";

cout << "-- 2\n";
m.insert(pair<string, A>( "b", B("bVal")));

As regards creation of instances, I read this as follows:
1. `B` gets created by my own code
1. that `B` gets copy-constructed into an `A` by `pair`
1. that last `A` instance then gets copied once more by the `map`, where it is inserted
Btw changing the `pair` in the `insert` line to a `pair<string, B>` did not do the trick, it only changed the 2nd step to create an `B` instead of the `A`, but the last step would *downgrade* it to an `A` again. The only instance in the map that remains until the map itself is eligible for destruction seems to be that last `A` instance.
What am I doing wrong and how am I supposed to get a derived class into a map? Use maps of the format
map<string, A*>

~B() { cout << "-B " << this << "\n"; }
};
Here's how I `insert` an instance of `B` into the `map`:
{
cout << "-- 1\n";
map<string, A> m;
cout << "-- 2\n";
m.insert(pair<string, A>( "b", B("bVal")));
cout << "-- 3\n";
}
cout << "-- 4 --\n";
The result of that:
-- 1
-- 2
+A 0051F620
+B 0051F620
*A 0051F5EC
*A 00BD8BAC
-A 0051F5EC
-B 0051F620
-A 0051F620
-- 3
-A 00BD8BAC
-- 4 --
As regards creation of instances, I read this as follows:
1. `B` gets created by my own code
1. that `B` gets copy-constructed into an `A` by `pair`
1. that last `A` instance then gets copied once more by the `map`, where it is inserted
Btw changing the `pair` in the `insert` line to a `pair<string, B>` did not do the trick, it only changed the 2nd step to create an `B` instead of the `A`, but the last step would *downgrade* it to an `A` again. The only instance in the map that remains until the map itself is eligible for destruction seems to be that last `A` instance.
What am I doing wrong and how am I supposed to get a derived class into a map? Use maps of the format
map<string, A*>
perhaps? | 0 |

===
So i've run into an annoying issue where i've set a wide border (15px) on a div and I have an element that is floated right inside of that div with a negative margin to top so that it slightly overlaps the border. This was working fine until I set the div to overflow-y:scroll and now instead of the the text overlapping the border the border overlaps the text. I'm at a loss as to why this occurs and how to fix it.

As the title suggests, I'm trying to inject a doctype at runtime on a page-by-page basis.
The application uses a single master with a gazillion content pages, so naturally I've tried inserting an `asp:contentplaceholder` control on the master, and using an `asp:content` control on the content page. This works in that the doctype element shows up when you view source, but it doesn't work in that the browser (IE8) is still running in Quirks mode for some god-forsaken reason.
Here's the placeholder on the master:
<asp:contentplaceholder id="doctype" runat="server" />
Here's the content panel on the page:
<asp:content contentplaceholderid="doctype" runat="server" >
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
</asp:content>
I'm a bit baffled as to why this isn't working, since the replacement should happen server-side, then the output gets sent to the browser with the doctype already in place...
Why am I doing this?
--------------------
I'm only doing this because specifying a doctype on the master means I would then need to go and fix the gazillion content pages before I can even begin to work on the assigned task. If I can figure out a way to inject a doctype via certain content pages, then I can effectively fix one page at a time until they are finished.
Which browsers does this affect?
--------------------------------
*Internet Explorer 8* is our primary target. It is, ironically, the browser that is effectively ignoring the injected doctype. When checking `document.doctype` at runtime after the DOM is loaded, it's returning `null`.
*Firefox* behaves differently. This technique actually works in Firefox, but doesn't really help [me] since all of our users are stuck with Internet Explorer 8. | asp.net | doctype | null | null | null | null | open | Why doesn't Internet Explorer 8 recognize the doctype when inserted at runtime?

pi = ProgressIndicator()
for x in somelongstuff:
do stuff
pi.update()
pi.print_totals()
Basically, it should output some kind of a progress bar with dots and dashes, and something like "234234 bytes processed" at the end.
I thought it would be nice to use it as a context manager:
with ProgressIndicator() as pi:
for x in somelongstuff:
do stuff
pi.update()
However there are a few things that concern me about this solution:
- extra amount of indentation makes the indicator feature appear more important than it actually is
- I don't want `ProgressIndicator` to handle any exceptions that might occur in the loop
Is this a valid use case for a context manager? What other solutions can you suggest?

if you add into jenkins start script the typical jvm system parameters for jmx:
-Dcom.sun.management.jmxremote.port=XXXX -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
you will always get
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: XXXX; nested exception is:
java.net.BindException: Address already in use
Excluding problems about /etc/hosts name resolutions or not free ports (already checked...).
Looking at documentation, jenkins' scripts are based on [winstone](http://winstone.sourceforge.net/). As far as I can see, winstone handles by itself another jvm process other than the one started via jenkins scripts.
I think both starting jvm and winstone inherit jvm system properties so the latter raises the exception above.
Following this thought, I tried removing the jvm parameters for jmx and setting them in a file winstone.properties (specifying --config parameter ) but this approach had no effects..

It basically loops over a list of HTML of a web auction site, if a user has not paid for to have the image shown in the main list. A default image is shown.
- My plugin use a jQuery Ajax request to load the auction page and find the main image to display as a thumbnail for any missing images. WORKS GREAT.
- The plugin finds the correct image url and update the HTML Dom to the new image and sets a new width.
The issue is, that the auction site tracks all pages views and saves it to a "recently viewed" section of the site "users can see any auctions they have clicked on"
ISSUE
- My plugin uses ajax and the cookies are sent via the jQuery ajax request. I am pretty sure I cannot modify the cookies in this request so the auction site tracks the request and for any listing that has a missing image this listing is now shown in my "recently viewed" even though I have not actually navigated to it.
1. Can I remove cookies for ajax request (I dont think I can)
2. Can chrome remove the cookie (only for the ajax requests)
3. Could I get chrome to make the request (eg curl, with no cookie?)
Just for the curious.

//adding a function to JQuery object
jQuery.slowEach = function( array, interval, callback ) {
if( ! array.length ) return;
var i = 0;
next();
function next() {
if( callback.call( array[i], i, array[i] ) !== false )
if( ++i < array.length )
setTimeout( next, interval );
}
return array;
};
//attaching a new method .slowEach()
jQuery.fn.slowEach = function( interval, callback ) {
return jQuery.slowEach( this, interval, callback );
};
// Show an element every half second
$('.reveal').slowEach( 500, function() {
$(this).show();
})
I just want to know if it's necessary to write the function plugin when I'm writing such method plugin, and whats the significance? If not, can I write the whole thing in the jQuery.fn.slowEach method without the function plugin?
Thanks!
