After reading [this](http://stackoverflow.com/questions/849684/jpanel-size-by-inner-components) I tried (in jython):

pan = JPanel()
pan.add(JLabel('beer'))
pan.add(JButton('get one', actionPerformed=printer))
pan.setMinimumSize(panel.getPreferredSize())
frame.add(pan)

however the panel can still be shrunk so far that it cuts off its components (in a JFrame or [here](http://stackoverflow.com/questions/11408971/use-button-as-renderer-for-list)), even if I apply the minimum size to the frame. How does one prevent this? ( I assume the preferred size I am getting si not what I want since with the default layout manager it seems to be the size of the largest subcomponent, but if I change it to e.g. `GridBagLayout` it seems to get smaller 9apply minsize to frame and try) | swing | jpanel | jython | null | null | null | open | Prevent JPanel from cutting off subcomponents

Specifically, you just need to create the suffix array of the text, sort it, and then instead of doing binary search to find the range so that you can figure out the number of occurences, you just compute the `LCP` for each succesive entry in the suffix array.
Although using a binary search to find the number of occurences of a pattern is obvious I can't figure out how the `LCP` helps find the number of occurences here.
For example for this suffix array for "banana":
LCP Suffix entry
N/A, a
1 , ana
3 , anana
0 , banana
0 , na
2 , nana
how does the `LCP` help to find the number of occurences of "banana" or "na" is not obvious to me.

The motion.magneticField.field.z shows the correct value (always the same value even when i initialize the CMMotionManager with a different device rotation).
How does this come?
Are the euler angles from CMAttitude not calculated agains the reference frame?
Any ideas how i get the euler angles calibrated to north?

I have around 25 properties of 4000 items (this is an intranet app, I do paging client side).
All the other browsers (IE9 too) work perfectly.
The warning appears when the received rest array is mapped to the collection of models after a fetch to the server.
This message appears as IE8 has [a limit of around 5 million operations][1] and it shows an annoying warning message when it reaches it.
I don't know how I can reach this limit with what it appears to me not a really huge amount of data.
I've learned that this limit can be increased by manipulating the windows registry on the client or with a [patch][2] Microsoft provides.
A more elegant solution is to use a workaround as described [here][3] that will insert a setTimeout on long running operation resetting the operation counter in IE8.
Now after the successful fetch of the data, backbone calls the parse method that will use internally the underscore.js map function.
I'd like to apply the workaround code without touching the underscore.js or backbone.js source code. Is this possible?

I've tried a number of solutions written in PHP (curl, multi curl, a couple of DIY curl parallel options) but none of them are fast enough.

I want to start off by saying I am not sure how to properly word what I am aiming to do, so there may be plentiful examples on how to do what I am trying to do, I just cannot find them.
That being said my explanation might be a bit wordy so I appreciate any and all help.
I am including a new feature on a previously created .Net webpage and sql database. The code currently returns a DataSet from the database and binds it to a datagrid. From there it is loaded into a table on the webpage. What my new column needs to do is take the primarykey from the current row and use it to call a stored procedure to get more data.

I want to do the following:--
1. I want to have a mysql localhost server and have a table in it in which i will keep username and password.
2. I will create a webpage with login option and once user clicks on submit then i will autenticate the user using the database i create above.
Following is what i did as of now:--
I am new to mysql and php too. I did a lot of search but was not able to understand what exactly i installed in my machine.
I downloaded mysql and installed it. I see a mysql cmd prompt. I create a database and i created a table in it.
Now how to i create a user? I tried creating it using
CREATE user xyz;
but it says attempting to connect and connection failed (what exactly is it trying to connect?)
I did a search for accessing a localhost server and i got the code which is
<?PHP
$user_name = "root";
$password = "";
$database = "addressbook";
$server = "127.0.0.1";
$db_handle = mysql_connect($server, $user_name, $password);
$db_found = mysql_select_db($database, $db_handle);
if ($db_found) {
print "Database Found ";
mysql_close($db_handle);
}
else {
print "Database NOT Found ";
}
?>
which looks fairly decent to me.

I included this **$.ajaxSetup** as I desperated attempt, but it has no effect.

public interface ReturnableScriptMethodSPI extends Runnable {
public String getDescription();
public String getFunctionName();
public String getCategory();
public void setArguments(Object[] args);
public Object returns();
}
This interface is then generated to a javascript function definition as follows:
public String generateScriptBinding() {
bindings.put("this"+method.getFunctionName(), method);
String scriptx = "function " + method.getFunctionName()+"() {\n"
+ "\tvar args = java.lang.reflect.Array.newInstance(java.lang.Object, arguments.length);\n"
+ "\tfor(var i = 0; i < arguments.length; i++) {\n"
+ "\t\targs[i] = arguments[i];\n"
+ "\t}\n"
+ "\tthis"+method.getFunctionName()+".setArguments(args);\n"
+ "\tthis"+method.getFunctionName()+".run();\n"
+ "\tvar tmp = this"+method.getFunctionName()+".returns();\n"
+ "\treturn tmp\n;"
+"}";
return scriptx;
}
...where bindings is a Bindings object as part of the class the generateScriptBinding() belongs to. Note that this method doesn't do the heavy lifting, it merely creates a string to pass to the heavy lifter--the Rhino script engine...more specifically, Sun's version.
Now for the most part, this works pretty well, but as the interface implementations grow, I'm beginning to see the following error:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: TypeError: GetMyGroups is not a function, it is sun.org.mozilla.javascript.internal.NativeJavaObject. (<Unknown source>#4)
Now, GetMyGroups is just one implementation of ReturnableScriptMethodSPI so the errors look exactly the same but with a different name swapped in for GetMyGroups.
Has anyone seen this error before and can comment on why it occurs as well as what the generator code might be doing wrong to cause the function definition to cause such an error?
Many thanks in advance!

In my application I have RootViewController as the app launches it adds a subview called "AuthCheck". In it I perform authentication checks displaying to user details of what's happening. In the AuthCheckController I have a call back method to handle async auth process as shown below.
- (void)shellAuthRequired: (ServiceResponse *)response {
[super shellAuthRequired:response];
if (response.hasError) {
[self showTryAgainAlert: response.errorText];

//[self.navigationController pushViewController:intview animated:YES];
[self.view addSubview:intview.view];
}
In this method as you see I forward the user to a new screen where I display necessary auth related details and the screen will have an continue button. When user clicks on "Continue" I load a new SubView called "WebViewController". Code below
-(IBAction)btnContinueToClicked:(id)sender
{
WebViewController *wview = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:nil];
[self.view addSubview:wview.view]
}
I get the exception "[IntroViewViewController performSelector:withObject:withObject:]: message sent to deallocated instance 0xd062f50" when I add new subview to be forwarded to.
What is causing this error?

It seems like "learn_params()" can deal with NaNs and the node state combinations that do not occur in the dataset. When I apply dirichlet priors to smoothen the 0 values, I get 'sensible' MLE distributions for all nodes. I have copied the script where I do this.

I'm getting the following javascript error:

I checked and the yii.debugtoolbar.js lib is installed under 'assets/84af4f51'. I also stepped through the php code and confirmed registerScriptFile() is being called for this file in YiiDebugToolbar.php.
Kind of stuck what's going on here. Is it a bug or is there some setup step I missed?

I'm currently stuck on what is (I hope a newby) problem with a rails project (this is my first rails project and so I apologise if I miss anything crucial). I've been at this for a couple of hours and can't seem to find any solutions. I have tried the solutions to the following threads with no avail.
[connect to local MySQL server through socket][1]
[Can't connect to local MySQL server through socket][2]
[Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)][3]
[Can't connect to local MySQL server through socket '/tmp/mysql.sock'][4]
The list goes on, anyway some of the threads are similar to my situation others are just clutching at straws. Let me give you a quick overview of my situation.
- The project has been developed on a mac
- I have recently set up a test server as a means of learning the deployment process
- The server is running Ubuntu Server 12.04
I managed to follow some tutorials to set it up including the [Capistrano][5] deployment tutorial up to the point of:
$ rake RAILS_ENV=production db:schema:load
which was where I first encountered the Can't connect to local MySQL server error.
if I run it with --trace I get the following output:
** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)

I would like to point out that the location /usr/share/ruby-rvm/gems/ruby-1.9.2-p318@rails_3_2/gems/mysql2-0.3.11/lib/mysql2/client.rb is valid. Also, mysql is running and I can access it with:
mysql -u production -p
I'm not sure how you could possibly need any more info from me but obviously if you do, let me know and I'll happily oblige, any help that you can give would be very much appreciated
Thanks in advance

| mysql | ruby-on-rails | ubuntu | null | null | null | open | Rails application unable to connect to mysql, Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2) (Mysql2::Error)
===
Hello lovely people of the stack!
I'm currently stuck on what is (I hope a newby) problem with a rails project (this is my first rails project and so I apologise if I miss anything crucial). I've been at this for a couple of hours and can't seem to find any solutions. I have tried the solutions to the following threads with no avail.
[connect to local MySQL server through socket][1]
[Can't connect to local MySQL server through socket][2]
[Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)][3]
[Can't connect to local MySQL server through socket '/tmp/mysql.sock'][4]
The list goes on, anyway some of the threads are similar to my situation others are just clutching at straws. Let me give you a quick overview of my situation.
- The project has been developed on a mac
- I have recently set up a test server as a means of learning the deployment process
- The server is running Ubuntu Server 12.04
I managed to follow some tutorials to set it up including the [Capistrano][5] deployment tutorial up to the point of:
$ rake RAILS_ENV=production db:schema:load
which was where I first encountered the Can't connect to local MySQL server error.
if I run it with --trace I get the following output:
** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
Can't connect to local MySQL server through socket '/var/run/mysqld/mysql.sock' (2)

Note that I have changed the location of the socket variable to correspond with what I believe is the .sock file on ubuntu as this differs from a standard install on mac OSX.

I'm not sure how you could possibly need any more info from me but obviously if you do, let me know and I'll happily oblige, any help that you can give would be very much appreciated

I have one table called flow_data
There is two attributes category and views.
category is int type and views is int type.
category has 1-5(for example num 0 is video and num 1 is pics) and numbers of view is based on how many times users click.
I want to query data that top5 views for each category.
SELECT DISTINCT id, cat, title, file , type , tags FROM flow_data ORDER BY views LIMIT 5
It only returns top5 views not based on each category.
Any thought? Thank you advance.

Hi,
i'm trying to animate the image of a UIButton between two different image.
Let's say i have two square images, on RED, on BLACK.
When i touch my Button, i want the image of the uibutton to loop from both images, in a smooth animation.
the loop animation must start whenever the user touch down the button and canceled when he touch Up inside or drag exit.
Here is what i do now :
-(void)startAnimation:(UIButton *)obj {
[UIView animateWithDuration:1 delay:0 options:(UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat) animations:^{
[obj setAlpha:0];
[obj setImage:[UIImage imageNamed:@"animated_on"] forState:UIControlStateNormal];
[obj setImage:[UIImage imageNamed:@"animated_on"] forState:UIControlStateHighlighted];
[obj setImage:[UIImage imageNamed:@"animated_on"] forState:UIControlStateDisabled];
[obj setImage:[UIImage imageNamed:@"animated_on"] forState:UIControlStateSelected];
} completion:^(BOOL finished) {
[obj setAlpha:1];
[obj setImage:nil forState:UIControlStateNormal];
[obj setImage:nil forState:UIControlStateHighlighted];
[obj setImage:nil forState:UIControlStateDisabled];
[obj setImage:nil forState:UIControlStateSelected];
}];
}
-(void)stopAnimation:(UIButton *)obj {
[obj.layer removeAllAnimations];
}
- (void)touchDownAnimation:(id)obj {
[self startAnimation:obj];
}
- (void)dragEnterAnimation:(id)obj {

}
- (void)dragExitAnimation:(id)obj {

}
- (void)touchUpInsideAnimation:(id)obj {
[self stopAnimation:obj];
}
- (void)viewDidLoad
{
[super viewDidLoad];
CGRect frame = CGRectMake(110, 180, 100, 100);
UIImageView *animatedButtonBackground = [[UIImageView alloc] initWithFrame:frame];
[animatedButtonBackground setImage:[UIImage imageNamed:@"animated_off"]];
[self.view addSubview:animatedButtonBackground];
UIButton *animatedButton = [UIButton buttonWithType:UIButtonTypeCustom];
[animatedButton setFrame:frame];
[animatedButton addTarget:self action:@selector(touchDownAnimation:) forControlEvents:UIControlEventTouchDown];
[animatedButton addTarget:self action:@selector(dragEnterAnimation:) forControlEvents:UIControlEventTouchDragEnter];
[animatedButton addTarget:self action:@selector(dragExitAnimation:) forControlEvents:UIControlEventTouchDragExit];
[animatedButton addTarget:self action:@selector(touchUpInsideAnimation:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:animatedButton];
}
it's kinda works, but involving an UIImageView in the process looks like a bad trick to do what i want...

it's kinda works, but involving an UIImageView in the process looks like a bad trick to do what i want...

It shows a select field with a modified behaviour. It does not use the standard picker, but a custom-built panel of the class test.view.Select. On initializing the main panel, the onMaskTap event of the select field gets modified so that it creates the custom select panel (if necessary), sets a link to it via the "caller" variable and shows it. On tapping a button, the modal Select window sets the appropriate value in the underlying select field and hides itself.
This works fine in Windows/Chrome, Android, IPhone - but not on the IPad. Here the modal popup windows shows only once. On subsequent taps it does not show. If, however, a alert window is shown on the tap action (line 24), then first the alert shows and then the popup.

Because I'm using ABS, it isn't possible to load the fragment directly in the xml file. This'll throw a ClassCastException. | 0 |

I have a calendar (using jQuery FullCalendar). And I want to implement a recurrence structure to the calendar. The best way would be to use a standard, such as iCal RRULE.
But what i'm trying to figure out is, what is the best way to store it in a MySQL database?
A simple (varchar field), containing: RRULE:FREQ=DAILY;INTERVAL=1;BYDAY=TU,WE,FR;UNTIL=20110713T075959Z;WKST=SU
Once I have it 'stored' in the database, how would I go about 'pulling' the data from the database to parse the recurrence to display onto my calendar?
Any help would be greatly appreciated. | php | date | recursion | calendar | fullcalendar | null | open | How to Store and Parse RRULE data
