I am using jQuery.ajax and setting the timeout to 60 seconds. So, if I do not get any response in 60 seconds, the call is aborted and an error is reported.
The problem now is any successive calls to the server after this point just keeps waiting, not just AJAX calls, even opening up a new page from the same server in a new window, just keeps waiting. The only way to get it working again is to restart the browser completely. What might be causing this?

No matter what functions of Canvas I used, even if I just use Canvas to draw a line, it will cause problem. The scenario is hard to describe clearly. I will try my best. Hope you know what I am talking about.
In my app, when users click a button, the popup panel which contains a DataGrid will show up. Under the popup panel, in RootLayoutPanel, I have a Canvas which draws some graphs. If Canvas and the DataGrid appeared in the same area (they "interlace"), the bug will appear (some unexpected weird scroll bars show up). On the other hand, if they don't appear in the same area, or I just do not let the Canvas start drawing if they interlace, then no problem at all. For example, if I move the Canvas away from underneath of popup panel which contains DataGrid,so that they do not interlace, DataGrid will have no problem.
I found someone have reported this bug in Google as well. And it is exactly what I encounter. But no one can answer why or provide some workaround.

We have been doing a fair amount of reading on SHA-2, Bcrypt, PBKDF2, and Scrypt. That being said, we are not security experts or cryptologists, and a lot of the technical aspects of the subject matter goes over our heads.
We understand the purpose of the blowfish derived algorithms and the benefit of a work factor. All make sense, and at this point we are leaning toward implementing either PBKDF2 or Bcrypt.
However, we were curious as to whether or not there was a benefit to using a SHA-2 algorithm in concert with either Bcrypt or PBKDF2. We had looked at the post:
http://security.stackexchange.com/questions/11552/would-it-make-sense-to-use-bcrypt-and-pbkdf2-together
But this is really more about using both Bcrypt and PBKDF2 together, and not a SHA-2.
Is there a benefit of leveraging a SHA-2 algorithm with either Bcrypt or PBKDF2? Or is it wasted effort/performance for no appreciable increase in actual security?
Thanks in advance for any insight anyone can provide.

In SQL Server 2008 R2 if I do:
select SYSDATETIMEOFFSET()
I get back GMT -6.
The TimeZone in Windows that SQL Server is running on is set GMT -7.
Any ideas why there is a difference? Is there somewhere in SQL Server I need to set the TimeZone?

It runs smoothly in chrome and IE9 (60 fps in chrome, a bit slower in IE but still smooth) but performs poorly in FF (currently tested in 13.0.1 and 14.0.1 build). It turns out that I have to largely decrease the number of object rendered in FF in order to make it smooth. But no such problem exists in IE and chrome.

window.msRequestAnimationFrame ||
function(callback, element){
window.setTimeout(callback, 1000 / 60);

function animate() {
requestAnimFrame( animate );
// ...some code for object to appear in order during a certain time, but does not affect the performance...
for( var i = 0, len = eyes.length; i < len; i++ ) {
var eye = eyes[i];
eye.update( mouse ); // rendering

The code specification should accord with that in the link http://paulirish.com/2011/requestanimationframe-for-smart-animating/ and have no problem in chrome and IE, but FF only.
Can anyone tell me how to improve this? Thanks
| javascript | html5 | firefox | canvas | requestanimationframe | null | open | canvas poor performance in FF
===
So I'm having a webpage locally running html5 canvas. It runs smoothly in chrome and IE9 (60 fps in chrome, a bit slower in IE but still smooth) but performs poorly in FF (currently tested in 13.0.1 and 14.0.1 build). It turns out that I have to largely decrease the number of object rendered in FF in order to make it smooth. But no such problem exists in IE and chrome.
I'm using requestAnimFrame method from shim as follows
window.requestAnimFrame = (function(){
return window.requestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.oRequestAnimationFrame ||
window.msRequestAnimationFrame ||
function(callback, element){
window.setTimeout(callback, 1000 / 60);
};
})();
My rendering code is
function animate() {
requestAnimFrame( animate );
// ...some code for object to appear in order during a certain time, but does not affect the performance...
for( var i = 0, len = eyes.length; i < len; i++ ) {
var eye = eyes[i];
eye.update( mouse ); // rendering
}
}
The code specification should accord with that in the link http://paulirish.com/2011/requestanimationframe-for-smart-animating/ and have no problem in chrome and IE, but FF only.
Can anyone tell me how to improve this? Thanks

This time I would to represent data by a function like :
def f3(c,t):
resultat=0
test=t-c[0]
if (test<0):
resultat = c[1]
else:
resultat = c[1]+c[2]*(t-c[0])+c[3]*(t-c[0])*(t-c[0])+c[4]*(t-c[0])*(t-c[0])*(t-c[0])
return resultat
t is a time vector and c[0] is a threshold (c[i] for the polynomial coefficients)
*(by the way the data can be represented by this function because I used it to generate the data example!)*
The function error is given by :
def e3(p,temps,y):
error = 0
i=0
for t in temps:
error = error + (f3(p,t)-y[i])**2
i=i+1
#cont = min(0,p[0])
#error = error +10000*(cont*cont)*(cont*cont*cont*cont)
return error
p3=[10,250,0,0,0] and T_out is a vector
The fitting operation is :
p3_min = fmin(e3,p3[:], args=(temps,T_out),xtol=0.0001,ftol=0.0001)
This instruction works very well for "classic" polynomial function but
for the f3 function (with a 'if' in it), p3_min is not as optimized as expected.
I tried to implement constraint like p[0]>0 or increase the number of iterations but I cannot manage to get the expected value.
Has anyone ever tried to fit data with a "threshold" function?
I would be grateful to get some help.

As some of you probably already saw, is there an error... because this don't work: ( item.SubItems.Add(dynamicbutton);)
So my first question is how can i show the button on the same line of the other info.
And my seccond question is maybey more advanged. How can i make an eventhandler for al these button dynamicly, and send some arguments with it...
Like in html / javascript it was something like :
<button OnClick="DoStuff(5,true);">do it!</button>
But how would that be in C#???

Further investigation showed that in my memory usage test my app was over 70mb in 5 minutes of testing. My native email app was only using 40mb. This cannot happen
I am using ARC and what I thought was that if I use something like
@property(nonatomic, strong)NSString *string;
ARC will dealloc this automatically. It doesn't seem to be doing that at all.
What I would like to know is if I can reduce my memory by using `dealloc` in my code (when I switched to ARC it deleted all my `dealloc` methods) or if there is another way to speed up my app.
To give you more information on what the app does here is a list of key points:
-Gets mail messages from webservice along with pdfs
-Stores arrays to check if messages have been read, deleted, or unread
-Mail tab checks for new messages from the webservice everytime someone clicks on the tab
-Same check for pdf files
Any information will help me a lot.

I've got a bit of an interesting question. Hope it's not already answered (wait, yes I do!) but I've looked and couldn't find it. (Hopefully not because it's not possible)

However in my join table (group_events), I have additional columns which provide extenuating circumstances to the event... I want this information to be available on the event object. (For example, whether attendance is mandatory or not etc)

Hello,
I'm trying to test whether the following calculation :

*where x & y are the values of the magnetic field's x & y axis, returned by the magneticField property, (in microTeslas)..*
can successfully convert those values into degrees
for that reason I've written the following bit of code :
#import "MyGameViewController.h"
#import "TestDegrees.h"
@interface MyGameViewController()
{
TestDegrees *test;
}
@end

counter++;

I am learning Java, and the following scenario hit my head:
class MyThread extends Thread {
void run(){
//a heavy function
}
}
And now in the main thread, I invoke this thread as:
public static void main(...){
new MyThread().start();
System.gc(); //just a request..
//end of main thread too.
//Reference to that MyThread object is now zero.
}
I ran that code. It seems the thread is still alive. The program ends when **all** the threads quit.
My questions:
- When the reference count is zero, wont the thread be eligible for GC? If it is really eligible, what is the behaviour of garbage collection? Will the thread be terminated?
- I know its a bad thing to do but is it well defined to not have `otherThread.join()` in `main()`?
I have a few explanation of myself (but I do not know how right I am -- the reason I made a post here):
- JVM maitains a reference to the thread as long as it is **active**. So ref count is never really zero.
- The executing function has an implicit `this` reference, so the ref count is again not zero.
Am I correct in any of the explanations above? Or is there any other explanation altogether?

I have class named "config" that have private string variable named "param".
I need to get from "config" class "param" variable sometimes as int type sometimes as bool type or string.
As I understand I need create 3 properties in config class,each property have to convert type,
as follow:
the first property converts string to int,
the second converts string to bool,
the third property gets me the string value.
The class should look something like this:
class Config
{
private string param;
public int
{
get
{
return int.parse(param);
}
}
public bool
{
get
{
return bool.tryparse(param);
}
}
public string
{
get
{
return param;
}
}
}
But I dont know how can those properties be used in accordance
to the variable type that I want to get out of class.
I hope you can help me!!
Thank you in advance!

My question is this. I need to write some in-house programs to do administrative tasks on all of our users in GMail. Is using OAuth the best way to go? All I really need to do is log in as the gmail administrator and run some automated tasks on each user account/data.
If OAuth is the best way to go, do I use the gmail domain key?
Thanks in advance, | 0 |

Now that the new and shiny Eclipse 4.2 is out of the oven, it feels more stable and somewhat snappier, *but* I instantly felt a dislike for some details of its UI:
- I find the "curved" look of the main toolbar distracting and it seems to me that it does not mix well with any other element in my desktop. It could just be a color issue, but the toolbar is prevalent enough to merit a specific mention.
- The default colors do not work well with the TFT/TN displays of the laptop and both desktop computers that I am using. The various gradients seem completely washed out, the tab separators are practically invisible and the toolbar curve looks totally weird.
It's also almost impossible to tell which view is active - Eclipse 3.x used a unique blue color for the active tab header. Juno uses a color-reversal in all inactive tabs, which probably sounds more visible, but in my opinion that effect is lost because the active tab is still in a shade of gray which is lost in the overall gray-ness of the new UI...
So, how do I get back to a more reasonable look and feel? Is there somewhere a theming option that would help?
PS.1: I use Eclipse/GTK on Linux...
PS.2: What happened to all the colors in Juno, anyway?
PS: Can we keep the new splash screen, though? *That* one, I like...

The engine is working fine, and is able to validate the CA trust, the validity period of the server certificate.
But what I'm missing is a validation that the certificate subject name matches the server name to which I'm connecting.
What's the best way to implement it, considering all the SSL extensions like [subject alternative names][1], etc?
I tried simply checking the subject name, but it doesn't work even with `google.nl`, the subject in the cert is `google.com`, and `google.nl` is only to be found in the alternative names extension.

I need to perform mathematical calculations on these entries and am looking for a more elegant formula/method than I've come up with so far.
I know about 1904 date system and * or / by 24 to convert back and forth, the problem is getting a formula that will recognize the text entry as a negative time value.
I've tried value(), *1, which both work on the text fields if the number is positive, but the "-" seems to mess those up. Even paste-special/add fails to recognize these as numbers.
Here's what I came up with that gets the job done, but it's just so ugly to me:
=IF(LEFT(E5,1)="-",((VALUE(RIGHT(E5,LEN(E5)-1)))*-1.0),VALUE(E5))
Obviously my text entry is in cell E5 in this example.
This works, so I'm not desperate for a solution, but for educational purposes (and smaller code) I'd like to know if there's a better way to this. Does anyone have a suggestion for something shorter, easier?
Thanks.
P.S. - an interesting tidbit here, I use Excel at work, but not at home, so I uploaded a sample spreadsheet to Google Docs, and it actually handles the Value() command on those entries properly. Weird, huh?
Thanks again for any suggestions.

How can you test if a string is a substring of any instance of a regular expression?
For example, all the instances of the regex
RA = /^a{1,2}c{1,2}$/
are
'ac', 'acc', 'aac', 'aacc'.
The string 'cc' is not an instance of the regex but is a substring of two instances of the regex. How can you test that 'c' has such a property?
Equivalently, how can you get (in general) a regex whose instances are all substrings of any instances of another regex.
For the example above, the regex
RB = /^a{0,2}c{0,2}$/
has the instances
'', 'c', 'cc', 'a', 'ac', 'acc', 'aa', 'aac', 'aacc'
which are all the substrings of the instances of RA.
How can you calculate such a RB from RA for any regex RA?
Thanks in advance!

extra_context = {
'user': list_user,
'time': str(list_time),
'latlng': list_latlng
}
All of the above variables are datatype of `python list`. Now i want to use these variable in Gmap v3 javascript. I found a following snippet for google map: (posting the main part)
<script type="text/javascript">
var map ;

var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {

center: latlng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};

var flightPlanCoordinates = [ {% for ip in latlng %}{{ ip }}{% endfor %}];
for(var i in flightPlanCoordinates){
var marker = add_marker(flightPlanCoordinates[i][0], flightPlanCoordinates[i][1],"Some title!","html for info box");

});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
return marker;
}
The above code shows a marker accoriding to the `latlng` list passed from the context. But the problem is occurring at that time when i also tried to pass `time and user` with the same way. It shows nothing on the Map. By the way i tried with this coide:
var user = [{% for i in user %}{{ i }}{% endfor %}];
var timestamp = [{% for y in time %}{{ y }}{% endfor %}];
Is that the right way? I am new in javascript i wrote according the `latlng` code.
I tried with `alert(timestamp)`. Nothing happens :(
Another problem is i have to pass these three parameter to `add_marker`
java script method. TO do this i have to run three for loop concurrently. Posting the pseudo code:
var user = [{% for i in user %}{{ i }}{% endfor %}];
var timestamp = [{% for y in time %}{{ y }}{% endfor %}];

There is other inputs that are also being submitted, so I am using this for each:
$a=$_REQUEST['request'];
foreach ($a as $name) {
foreach ($name as $key => $desc) {
if ($desc !== '') {
$note.= $key;
$note.= $desc;
}
}
}
This gets all the data fine if the user checks ONE checkbox, but if the user checks both checkboxes, only the value of the FIRST checkbox is shown.
What do I need to do here in order to get both values? | 0 |
