Programs & Examples On #Logout

Introduction

The ViewExpiredException will be thrown whenever the javax.faces.STATE_SAVING_METHOD is set to server (default) and the enduser sends a HTTP POST request on a view via <h:form> with <h:commandLink>, <h:commandButton> or <f:ajax>, while the associated view state isn't available in the session anymore.

The view state is identified as value of a hidden input field javax.faces.ViewState of the <h:form>. With the state saving method set to server, this contains only the view state ID which references a serialized view state in the session. So, when the session is expired for some reason (either timed out in server or client side, or the session cookie is not maintained anymore for some reason in browser, or by calling HttpSession#invalidate() in server, or due a server specific bug with session cookies as known in WildFly), then the serialized view state is not available anymore in the session and the enduser will get this exception. To understand the working of the session, see also How do servlets work? Instantiation, sessions, shared variables and multithreading.

There is also a limit on the amount of views JSF will store in the session. When the limit is hit, then the least recently used view will be expired. See also com.sun.faces.numberOfViewsInSession vs com.sun.faces.numberOfLogicalViews.

With the state saving method set to client, the javax.faces.ViewState hidden input field contains instead the whole serialized view state, so the enduser won't get a ViewExpiredException when the session expires. It can however still happen on a cluster environment ("ERROR: MAC did not verify" is symptomatic) and/or when there's a implementation-specific timeout on the client side state configured and/or when server re-generates the AES key during restart, see also Getting ViewExpiredException in clustered environment while state saving method is set to client and user session is valid how to solve it.

Regardless of the solution, make sure you do not use enableRestoreView11Compatibility. it does not at all restore the original view state. It basically recreates the view and all associated view scoped beans from scratch and hereby thus losing all of original data (state). As the application will behave in a confusing way ("Hey, where are my input values..??"), this is very bad for user experience. Better use stateless views or <o:enableRestorableView> instead so you can manage it on a specific view only instead of on all views.

As to the why JSF needs to save view state, head to this answer: Why JSF saves the state of UI components on server?

Avoiding ViewExpiredException on page navigation

In order to avoid ViewExpiredException when e.g. navigating back after logout when the state saving is set to server, only redirecting the POST request after logout is not sufficient. You also need to instruct the browser to not cache the dynamic JSF pages, otherwise the browser may show them from the cache instead of requesting a fresh one from the server when you send a GET request on it (e.g. by back button).

The javax.faces.ViewState hidden field of the cached page may contain a view state ID value which is not valid anymore in the current session. If you're (ab)using POST (command links/buttons) instead of GET (regular links/buttons) for page-to-page navigation, and click such a command link/button on the cached page, then this will in turn fail with a ViewExpiredException.

To fire a redirect after logout in JSF 2.0, either add <redirect /> to the <navigation-case> in question (if any), or add ?faces-redirect=true to the outcome value.

<h:commandButton value="Logout" action="logout?faces-redirect=true" />

or

public String logout() {
    // ...
    return "index?faces-redirect=true";
}

To instruct the browser to not cache the dynamic JSF pages, create a Filter which is mapped on the servlet name of the FacesServlet and adds the needed response headers to disable the browser cache. E.g.

@WebFilter(servletNames={"Faces Servlet"}) // Must match <servlet-name> of your FacesServlet.
public class NoCacheFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest req = (HttpServletRequest) request;
        HttpServletResponse res = (HttpServletResponse) response;

        if (!req.getRequestURI().startsWith(req.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER)) { // Skip JSF resources (CSS/JS/Images/etc)
            res.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
            res.setHeader("Pragma", "no-cache"); // HTTP 1.0.
            res.setDateHeader("Expires", 0); // Proxies.
        }

        chain.doFilter(request, response);
    }

    // ...
}

Avoiding ViewExpiredException on page refresh

In order to avoid ViewExpiredException when refreshing the current page when the state saving is set to server, you not only need to make sure you are performing page-to-page navigation exclusively by GET (regular links/buttons), but you also need to make sure that you are exclusively using ajax to submit the forms. If you're submitting the form synchronously (non-ajax) anyway, then you'd best either make the view stateless (see later section), or to send a redirect after POST (see previous section).

Having a ViewExpiredException on page refresh is in default configuration a very rare case. It can only happen when the limit on the amount of views JSF will store in the session is hit. So, it will only happen when you've manually set that limit way too low, or that you're continuously creating new views in the "background" (e.g. by a badly implemented ajax poll in the same page or by a badly implemented 404 error page on broken images of the same page). See also com.sun.faces.numberOfViewsInSession vs com.sun.faces.numberOfLogicalViews for detail on that limit. Another cause is having duplicate JSF libraries in runtime classpath conflicting each other. The correct procedure to install JSF is outlined in our JSF wiki page.

Handling ViewExpiredException

When you want to handle an unavoidable ViewExpiredException after a POST action on an arbitrary page which was already opened in some browser tab/window while you're logged out in another tab/window, then you'd like to specify an error-page for that in web.xml which goes to a "Your session is timed out" page. E.g.

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/WEB-INF/errorpages/expired.xhtml</location>
</error-page>

Use if necessary a meta refresh header in the error page in case you intend to actually redirect further to home or login page.

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>Session expired</title>
        <meta http-equiv="refresh" content="0;url=#{request.contextPath}/login.xhtml" />
    </head>
    <body>
        <h1>Session expired</h1>
        <h3>You will be redirected to login page</h3>
        <p><a href="#{request.contextPath}/login.xhtml">Click here if redirect didn't work or when you're impatient</a>.</p>
    </body>
</html>

(the 0 in content represents the amount of seconds before redirect, 0 thus means "redirect immediately", you can use e.g. 3 to let the browser wait 3 seconds with the redirect)

Note that handling exceptions during ajax requests requires a special ExceptionHandler. See also Session timeout and ViewExpiredException handling on JSF/PrimeFaces ajax request. You can find a live example at OmniFaces FullAjaxExceptionHandler showcase page (this also covers non-ajax requests).

Also note that your "general" error page should be mapped on <error-code> of 500 instead of an <exception-type> of e.g. java.lang.Exception or java.lang.Throwable, otherwise all exceptions wrapped in ServletException such as ViewExpiredException would still end up in the general error page. See also ViewExpiredException shown in java.lang.Throwable error-page in web.xml.

<error-page>
    <error-code>500</error-code>
    <location>/WEB-INF/errorpages/general.xhtml</location>
</error-page>

Stateless views

A completely different alternative is to run JSF views in stateless mode. This way nothing of JSF state will be saved and the views will never expire, but just be rebuilt from scratch on every request. You can turn on stateless views by setting the transient attribute of <f:view> to true:

<f:view transient="true">

</f:view>

This way the javax.faces.ViewState hidden field will get a fixed value of "stateless" in Mojarra (have not checked MyFaces at this point). Note that this feature was introduced in Mojarra 2.1.19 and 2.2.0 and is not available in older versions.

The consequence is that you cannot use view scoped beans anymore. They will now behave like request scoped beans. One of the disadvantages is that you have to track the state yourself by fiddling with hidden inputs and/or loose request parameters. Mainly those forms with input fields with rendered, readonly or disabled attributes which are controlled by ajax events will be affected.

Note that the <f:view> does not necessarily need to be unique throughout the view and/or reside in the master template only. It's also completely legit to redeclare and nest it in a template client. It basically "extends" the parent <f:view> then. E.g. in master template:

<f:view contentType="text/html">
    <ui:insert name="content" />
</f:view>

and in template client:

<ui:define name="content">
    <f:view transient="true">
        <h:form>...</h:form>
    </f:view>
</f:view>

You can even wrap the <f:view> in a <c:if> to make it conditional. Note that it would apply on the entire view, not only on the nested contents, such as the <h:form> in above example.

Unrelated to the concrete problem, using HTTP POST for pure page-to-page navigation isn't very user/SEO friendly. In JSF 2.0 you should really prefer <h:link> or <h:button> over the <h:commandXxx> ones for plain vanilla page-to-page navigation.

So instead of e.g.

<h:form id="menu">
    <h:commandLink value="Foo" action="foo?faces-redirect=true" />
    <h:commandLink value="Bar" action="bar?faces-redirect=true" />
    <h:commandLink value="Baz" action="baz?faces-redirect=true" />
</h:form>

better do

<h:link value="Foo" outcome="foo" />
<h:link value="Bar" outcome="bar" />
<h:link value="Baz" outcome="baz" />

• How to navigate in JSF? How to make URL reflect current page (and not previous one)

Instead of a button, put a link and navigate it to another page

<a href="logout.php">Logout</a>

Then in logout.php page, use

session_start();
session_destroy();
header('Location: login.php');
exit;

This works as of now - and is documented on facebook's site @ http://developers.facebook.com/docs/authentication/. Not sure how recently it was added to the documentation, pretty sure it wasn't there when I checked Feb-2012

You can programmatically log the user our of Facebook by redirecting the user to

https://www.facebook.com/logout.php?next=YOUR_REDIRECT_URL&access_token=USER_ACCESS_TOKEN

EDIT: Add logout action.

1. First of all prepare the app delegate file

AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (nonatomic) BOOL authenticated;

@end

AppDelegate.m

#import "AppDelegate.h"
#import "User.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    User *userObj = [[User alloc] init];
    self.authenticated = [userObj userAuthenticated];

    return YES;
}

2. Create a class named User.

User.h

#import <Foundation/Foundation.h>

@interface User : NSObject

- (void)loginWithUsername:(NSString *)username andPassword:(NSString *)password;
- (void)logout;
- (BOOL)userAuthenticated;

@end

User.m

#import "User.h"

@implementation User

- (void)loginWithUsername:(NSString *)username andPassword:(NSString *)password{

    // Validate user here with your implementation
    // and notify the root controller
    [[NSNotificationCenter defaultCenter] postNotificationName:@"loginActionFinished" object:self userInfo:nil];
}

- (void)logout{
    // Here you can delete the account
}

- (BOOL)userAuthenticated {

    // This variable is only for testing
    // Here you have to implement a mechanism to manipulate this
    BOOL auth = NO;

    if (auth) {
        return YES;
    }

    return NO;
}

3. Create a new controller RootViewController and connected with the first view, where login button live. Add also a Storyboard ID: "initialView".

RootViewController.h

#import <UIKit/UIKit.h>
#import "LoginViewController.h"

@protocol LoginViewProtocol <NSObject>

- (void)dismissAndLoginView;

@end

@interface RootViewController : UIViewController

@property (nonatomic, weak) id <LoginViewProtocol> delegate;
@property (nonatomic, retain) LoginViewController *loginView;


@end

RootViewController.m

#import "RootViewController.h"

@interface RootViewController ()

@end

@implementation RootViewController

@synthesize loginView;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)loginBtnPressed:(id)sender {

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(loginActionFinished:)
                                                 name:@"loginActionFinished"
                                               object:loginView];

}

#pragma mark - Dismissing Delegate Methods

-(void) loginActionFinished:(NSNotification*)notification {

    AppDelegate *authObj = (AppDelegate*)[[UIApplication sharedApplication] delegate];
    authObj.authenticated = YES;

    [self dismissLoginAndShowProfile];
}

- (void)dismissLoginAndShowProfile {
    [self dismissViewControllerAnimated:NO completion:^{
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
        UITabBarController *tabView = [storyboard instantiateViewControllerWithIdentifier:@"profileView"];
        [self presentViewController:tabView animated:YES completion:nil];
    }];


}

@end

4. Create a new controller LoginViewController and connected with the login view.

LoginViewController.h

#import <UIKit/UIKit.h>
#import "User.h"

@interface LoginViewController : UIViewController

LoginViewController.m

#import "LoginViewController.h"
#import "AppDelegate.h"

- (void)viewDidLoad
{
    [super viewDidLoad];
}

- (IBAction)submitBtnPressed:(id)sender {
    User *userObj = [[User alloc] init];

    // Here you can get the data from login form
    // and proceed to authenticate process
    NSString *username = @"username retrieved through login form";
    NSString *password = @"password retrieved through login form";
    [userObj loginWithUsername:username andPassword:password];
}

@end

5. At the end add a new controller ProfileViewController and connected with the profile view in the tabViewController.

ProfileViewController.h

#import <UIKit/UIKit.h>

@interface ProfileViewController : UIViewController

@end

ProfileViewController.m

#import "ProfileViewController.h"
#import "RootViewController.h"
#import "AppDelegate.h"
#import "User.h"

@interface ProfileViewController ()

@end

@implementation ProfileViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

}

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    if(![(AppDelegate*)[[UIApplication sharedApplication] delegate] authenticated]) {

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

        RootViewController *initView =  (RootViewController*)[storyboard instantiateViewControllerWithIdentifier:@"initialView"];
        [initView setModalPresentationStyle:UIModalPresentationFullScreen];
        [self presentViewController:initView animated:NO completion:nil];
    } else{
        // proceed with the profile view
    }
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)logoutAction:(id)sender {

   User *userObj = [[User alloc] init];
   [userObj logout];

   AppDelegate *authObj = (AppDelegate*)[[UIApplication sharedApplication] delegate];
   authObj.authenticated = NO;

   UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

   RootViewController *initView =  (RootViewController*)[storyboard instantiateViewControllerWithIdentifier:@"initialView"];
   [initView setModalPresentationStyle:UIModalPresentationFullScreen];
   [self presentViewController:initView animated:NO completion:nil];

}

@end

LoginExample is a sample project for extra help.

The folder being password protected has nothing to do with PHP!

The method being used is called "Basic Authentication". There are no cross-browser ways to "logout" from it, except to ask the user to close and then open their browser...

Here's how you you could do it in PHP instead (fully remove your Apache basic auth in .htaccess or wherever it is first):

login.php:

<?php
session_start();
//change 'valid_username' and 'valid_password' to your desired "correct" username and password
if (! empty($_POST) && $_POST['user'] === 'valid_username' && $_POST['pass'] === 'valid_password')
{
    $_SESSION['logged_in'] = true;
    header('Location: /index.php');
}
else
{
    ?>

    <form method="POST">
    Username: <input name="user" type="text"><br>
    Password: <input name="pass" type="text"><br><br>
    <input type="submit" value="submit">
    </form>

    <?php
}

index.php

<?php
session_start();
if (! empty($_SESSION['logged_in']))
{
    ?>

    <p>here is my super-secret content</p>
    <a href='logout.php'>Click here to log out</a>

    <?php
}
else
{
    echo 'You are not logged in. <a href="login.php">Click here</a> to log in.';
}

logout.php:

<?php
session_start();
session_destroy();
echo 'You have been logged out. <a href="/">Go back</a>';

Obviously this is a very basic implementation. You'd expect the usernames and passwords to be in a database, not as a hardcoded comparison. I'm just trying to give you an idea of how to do the session thing.

Hope this helps you understand what's going on.

Go to PHPMyAdmin in your browser

Settings > Features > Change the value of Login cookie validity > Save

NOTE: You will have to do this per session.

In Laravel 5.1+, you can use the value() instead of pluck.

To get first occurence, You can either use

DB::table('users')->value('name');

or use,

DB::table('users')->where('id', 1)->pluck('name')->first();

This can happen if you call

 .SingleOrDefault() 

on an IEnumerable with 2 or more elements.

Jim Tollan's answer works great, but I got the Error: Keyword not supported 'data source'. To solve this problem I had to change this part of his code:

// add a reference to System.Configuration
var entityCnxStringBuilder = new EntityConnectionStringBuilder
    (System.Configuration.ConfigurationManager
            .ConnectionStrings[configNameEf].ConnectionString);

to this:

// add a reference to System.Configuration
var entityCnxStringBuilder = new EntityConnectionStringBuilder
{
    ProviderConnectionString = new  SqlConnectionStringBuilder(System.Configuration.ConfigurationManager
               .ConnectionStrings[configNameEf].ConnectionString).ConnectionString
};

I'm really sorry. I know that I should't use answers to respond to other answers, but my answer is too long for a comment :(

<ToggleButton 
    android:id="@+id/togglebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textOn="Vibrate on"
    android:textOff="Vibrate off"
    android:onClick="onToggleClicked"/>

Within the Activity that hosts this layout, the following method handles the click event:

public void onToggleClicked(View view) {
    // Is the toggle on?
    boolean on = ((ToggleButton) view).isChecked();

    if (on) {
        // Enable vibrate
    } else {
        // Disable vibrate
    }
}

Check http://msdn.microsoft.com/en-us/library/dd203099.aspx

under Cryptography Application Block.

Don't know if you will get your answer, but it's worth a try.

Edit after Comment.

Ok then check this code.

using System.Security.Cryptography;


public static string DecryptEncryptedData(stringBase64EncryptedData, stringPathToPrivateKeyFile) { 
    X509Certificate2 myCertificate; 
    try{ 
        myCertificate = new X509Certificate2(PathToPrivateKeyFile); 
    } catch{ 
        throw new CryptographicException("Unable to open key file."); 
    } 

    RSACryptoServiceProvider rsaObj; 
    if(myCertificate.HasPrivateKey) { 
         rsaObj = (RSACryptoServiceProvider)myCertificate.PrivateKey; 
    } else 
        throw new CryptographicException("Private key not contained within certificate."); 

    if(rsaObj == null) 
        return String.Empty; 

    byte[] decryptedBytes; 
    try{ 
        decryptedBytes = rsaObj.Decrypt(Convert.FromBase64String(Base64EncryptedData), false); 
    } catch { 
        throw new CryptographicException("Unable to decrypt data."); 
    } 

    //    Check to make sure we decrpyted the string 
   if(decryptedBytes.Length == 0) 
        return String.Empty; 
    else 
        return System.Text.Encoding.UTF8.GetString(decryptedBytes); 
} 

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).

instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)

If you are using JDK 1.6 or higher then you can override the manifest attribute via e flag of Jar tool. (Read - Setting an Entry Point with the JAR Tool):

Example:

package pack;

public class Test
{
  public static void main(String []args)  
   {
     System.out.println("Hello World");
    }
}

Compile and run Jar tool,

c:\>jar cfe app.jar pack.Test pack/Test.class

Invoke app

c:>java -jar app.jar

import json
import urllib

url = 'http://example.com/file.json'
r = urllib.request.urlopen(url)
data = json.loads(r.read().decode(r.info().get_param('charset') or 'utf-8'))
print(data)

urllib, for Python 3.4
HTTPMessage, returned by r.info()

I think that your two examples are actually only one: the free() should occur only at the end of the process, which as you point out is useless since the process is terminating.

In you second example though, the only difference is that you allow an undefined number of malloc(), which could lead to running out of memory. The only way to handle the situation is to check the return code of malloc() and act accordingly.

The APK Scanner can be show the information of APK file on PC.
also, can be pull an apk file from the android device.
And can be link to other tools.(JADX-GUI, JD-GUI...)

enter image description here

This is because str.index(ch) will return the index where ch occurs the first time. Try:

def find(s, ch):
    return [i for i, ltr in enumerate(s) if ltr == ch]

This will return a list of all indexes you need.

P.S. Hugh's answer shows a generator function (it makes a difference if the list of indexes can get large). This function can also be adjusted by changing [] to ().

NSNumber may be good for you in this case.

NSString *inStr = [NSString stringWithFormat:@"%d", 
                    [NSNumber numberWithInteger:[month intValue]]];

Add .idea and *.iml to .gitignore, you don't need those files to successfully import and compile the project.

In the manifest:

<activity  android:name=".YourActivity"
android:screenOrientation="portrait"
android:configChanges="orientation|screenSize">

In your activity:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setContentView(R.layout.your_activity_layout);

var path = "path/to/myfile.png?foo=bar#hash";

console.log(
    path.replace(/(\?.*)|(#.*)/g, "")
);

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

All the other solutions work for Microsoft Edge (legacy) and on Windows 10 only. As of 2020, it will be discontinued and replaced by Microsoft Edge (Chromium based).

The solution that works with the new Edge on Windows 7, 8 and 10 is :

None of yours are solved my problem. But, I found a good solution for me to work properly right now. In between tags write this code:

<div style="position: fixed; z-index: -99; width: 100%; height: 100%">
  <iframe frameborder="0" height="100%" width="100%" 
    src="https://youtube.com/embed/**[CHANGE HERE WITH YOUR YOUTUBE VIDEO ID]**?autoplay=1&controls=0&showinfo=0&autohide=1">

</div>

It surprises me that this is a highly voted answers without mentioning the origin of MVVM. MVVM is a popular term used in Microsoft community and it is originated from Martin Fowler's Presentation Model. So to understand the motive of the pattern and the differences with others, the original article about the pattern is the first thing to read.

There's also COM.

There are technicalities, but I'd say the advantage is that you'll be able to call methods that you can define.

MSDN offers C# COM interop tutorials. Please search because these links do change.

To get started rightaway go here...

Method 1.

Using `ngModel`.

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="text" placeholder="Search..."  [(ngModel)]="searchValue">
      <button (click)="clearSearch()">Clear</button>
    </div>
  `,
})
export class App {
  searchValue:string = '';
  clearSearch() {
    this.searchValue = null;
  }
}

Plunker code: Plunker1

Method 2.

Using null value instead of empty quotation marks.

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="text" placeholder="Search..." [value]="searchValue">
      <button (click)="clearSearch()">Clear</button>
    </div>
  `,
})
export class App {
  searchValue:string = '';
  clearSearch() {
    this.searchValue = null;
  }
}

Plunker code: Plunker2

The below code stores the return value in to the variable retVal and then MsgBox can be used to display the value:

Dim retVal As Integer
retVal = test()
Msgbox retVal

I was also facing a similar issue ("no runnable methods..") on running the simplest of simple piece of code (Using @Test, @Before etc.) and found the solution nowhere. I was using Junit4 and Eclipse SDK version 4.1.2. Resolved my problem by using the latest Eclipse SDK 4.2.2. I hope this helps people who are struggling with a somewhat similar issue.

Set the anchor property of the control to hook to all sides of the parent - top, bottom, left, and right.

Here you go:

private Stream GenerateStreamFromString(String p)
{
    Byte[] bytes = UTF8Encoding.GetBytes(p);
    MemoryStream strm = new MemoryStream();
    strm.Write(bytes, 0, bytes.Length);
    return strm;
}

I am not sure about be the best way, but works fine and all code stays in your ArrayAdapter.

    this.context = context;

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.telefone_form, parent, false);

    tipoEditText = (EditText) view.findViewById(R.id.telefone_form_tipo);
    telefoneEditText = (EditText) view.findViewById(R.id.telefone_form_telefone);
    deleteImageView = (ImageView) view.findViewById(R.id.telefone_form_delete_image);

    final int i = position;
    final Telefone telefone = this.getItem(position);
    tipoEditText.setText(telefone.getTipo());
    telefoneEditText.setText(telefone.getTelefone());

    TextWatcher tipoTextWatcher = new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        @Override
        public void afterTextChanged(Editable s) {
            telefoneArrayAdapter.getItem(i).setTipo(s.toString());
            telefoneArrayAdapter.getItem(i).setIsDirty(true);
        }
    };

    TextWatcher telefoneTextWatcher = new TextWatcher() {
        @Override

        }

        @Override

        @Override
        public void afterTextChanged(Editable s) {

            telefoneArrayAdapter.getItem(i).setIsDirty(true);

You will also get this if git doesn't have permissions to read the config files. It will just go up in the hierarchy tree until it needs to cross file systems.

function converToLocalTime(serverDate) {

    var dt = new Date(Date.parse(serverDate));
    var localDate = dt;
    
    var gmt = localDate;
        var min = gmt.getTime() / 1000 / 60; // convert gmt date to minutes
        var localNow = new Date().getTimezoneOffset(); // get the timezone
        // offset in minutes
        var localTime = min - localNow; // get the local time

    var dateStr = new Date(localTime * 1000 * 60);
    // dateStr = dateStr.toISOString("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"); // this will return as just the server date format i.e., yyyy-MM-dd'T'HH:mm:ss.SSS'Z'
    dateStr = dateStr.toString("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
    return dateStr;
}

From MSDN:

A String object is a sequential collection of System.Char objects that represent a string.

So you can use this:

var howManyBytes = yourString.Length * sizeof(Char);

Assuming your project root is the current working directory, this should work:

// require built-in path module
path = require('path');

// require file relative to current working directory
config = require( path.resolve('.','config.js') );

If you have a process that already generates and returns an Image type, you can alter the bind and not have to modify any additional image creation code.

Refer to the ".Source" of the image in the binding statement.

XAML

<Image Name="imgOpenClose" Source="{Binding ImageOpenClose.Source}"/>

View Model Field

private Image _imageOpenClose;
public Image ImageOpenClose
{
    get
    {
        return _imageOpenClose;
    }
    set
    {
        _imageOpenClose = value;
        OnPropertyChanged();
    }
}

xml:space="preserve" has to work for all compliant XML parsers.

However, note that in HTML the line break is just whitespace and NOT a line break (this is represented with the <br /> (X)HTML tag, maybe this is the problem which you are facing.

You can also add 
 and/or 
 to insert CR/LF characters.

The Sony Tablet P is old, but it can switch between 32:15 and 32:30 for each app in landscape mode, and vice-versa in portrait mode, so that's a minimum range to aim for

Based on the answers provided, I decided to make a quick plugin to do this:

(function($){
    $.fn.moveTo = function(selector){
        return this.each(function(){
            var cl = $(this).clone();
            $(cl).appendTo(selector);
            $(this).remove();
        });
    };
})(jQuery);

Usage:

$('#nodeToMove').moveTo('#newParent');

What is the utility of an only one Ampersand? This morning, I made a launcher in the XFCE panel (in Manjaro+XFCE) to launch 2 passwords managers simultaneously:

sh -c "keepassx && password-gorilla"
or
sh -c "keepassx; password-gorilla"

But it does not work as I want. I.E., the first app starts but the second starts only when the previous is closed

However, I found that (with only one ampersand):

sh -c "keepassx & password-gorilla"

and it works as I want now...

Using an escaped string (a.k.a. escaped value):

width: ~"calc(100% - 200px)";

Also, in case you need to mix Less math with escaped strings:

width: calc(~"100% - 15rem +" (10px+5px) ~"+ 2em");

Compiles to:

width: calc(100% - 15rem + 15px + 2em);

This works as Less concatenates values (the escaped strings and math result) with a space by default.

Whilst M4N's answer (#if (!DEBUG)) makes most sense, another option could be to use the preprocessor to amend other flag's values; e.g.

bool isRelease = true;
#if DEBUG
    isRelease = false;
#endif

Or better, rather than referring to whether we're in release or debug mode, use flags that define the expected behavior and set them based on the mode:

bool sendEmails = true;
#if DEBUG
    sendEmails = false;
#endif

This is different to using preprocessor flags, in that the flags are still there in production, so you incur the overhead of if (sendEmails) {/* send mails */} each time that code's called, rather than the code existing in release but not existing in debug, but this can be advantageous; e.g. in your tests you may want to call your SendEmails() method but on a mock, whilst running in debug to get additional output.

This worked for me with log4j2 and xml parameters:

You cannot show an alert from a controller. There is one way communication from the client to the server.The server can therefore not tell the client to do anything. The client requests and the server gives a response.

You therefore need to use javascript when the response returns to show a messagebox of some sort.

OR

using jquery on the button that calls the controller action

<script>
 $(document).ready(function(){
  $("#submitButton").on("click",function()
  {
   alert('Your Message');
  });

});
<script>

This solution is deprecated

failure|fail|error() is deprecated and will be removed in 2.1, please use promise-style instead.

so you have to use

Project.update(

    // Set Attribute values 
    {
        title: 'a very different title now'
    },

    // Where clause / criteria 
    {
        _id: 1
    }

).then(function() {

    console.log("Project with id =1 updated successfully!");

}).catch(function(e) {
    console.log("Project update failed !");
})

And you can use .complete() as well

[checked 27 Nov 2020 and confirmed to be still accurate with Xcode 12.1]

The most convenient way these days: Xcode provides a code snippet to do this where you just have to enter the delay value and the code you wish to run after the delay.

1. click on the + button at the top right of Xcode.
2. search for after
3. It will return only 1 search result, which is the desired snippet (see screenshot). Double click it and you're good to go.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

This kind of an old post and in most cases I think the answer that has been upvoted the most will work for people.

In Lollipop on a GPE HTC M8 I was still having problems. The below steps worked for me.

1. Go to Settings
2. Tap on Storage
3. Tap on 3 dots in the top right
4. Tap on USB Computer Connection
5. UNCHECK MTP
6. UNCHECK PTP
7. Back in your console, type adb devices

Now you should get the RSA popup on your phone.

I'll tell you what worked for me:

int id = int.Parse(insertItem.OwnerTableView.DataKeyValues[insertItem.ItemIndex]["id_usuario"].ToString());

var query = user.First(x => x.id_usuario == id);
tbUsername.Text = query.username;
tbEmail.Text = query.email;
tbPassword.Text = query.password;

My id is the row I want to query, in this case I got it from a radGrid, then I used it to query, but this query returns a row, then you can assign the values you got from the query to textbox, or anything, I had to assign those to textbox.

Google helps a lot.

The above answers helped me to solve my issue specially the first answer. But adding to that point after the checking the version of python and we need it to be 64 bit version.

Based on the operating system you have we can use the following command to install tensorflow using pip command.

The following link has google api links which can be added at the end of the following command to install tensorflow in your respective machine.

Root command: python -m pip install --upgrade (link) link : respective OS link present in this link

POSIX is a standard for operating systems that was supposed to make it easier to write cross-platform software. It's an especially big deal in the world of Unix.

Unfortunately, there is a character limit so this will be in many parts. First thing to note is that return and print are statements, not functions, but that is just semantics.

I’ll start with a basic explanation. print just shows the human user a string representing what is going on inside the computer. The computer cannot make use of that printing. return is how a function gives back a value. This value is often unseen by the human user, but it can be used by the computer in further functions.

On a more expansive note, print will not in any way affect a function. It is simply there for the human user’s benefit. It is very useful for understanding how a program works and can be used in debugging to check various values in a program without interrupting the program.

return is the main way that a function returns a value. All functions will return a value, and if there is no return statement (or yield but don’t worry about that yet), it will return None. The value that is returned by a function can then be further used as an argument passed to another function, stored as a variable, or just printed for the benefit of the human user. Consider these two programs:

def function_that_prints():
    print "I printed"

def function_that_returns():
    return "I returned"

f1 = function_that_prints()
f2 = function_that_returns()

print "Now let us see what the values of f1 and f2 are"

print f1 --->None

print f2---->"I returned"

When function_that_prints ran, it automatically printed to the console "I printed". However, the value stored in f1 is None because that function had no return statement.

When function_that_returns ran, it did not print anything to the console. However, it did return a value, and that value was stored in f2. When we printed f2 at the end of the code, we saw "I returned"

We just open-sourced this jquery plug-in Github: tactivos/jquery-sew.

Short answer: I think tgbaggio is right. You hit HDFS throughput limits on your executors.

I think the answer here may be a little simpler than some of the recommendations here.

The clue for me is in the cluster network graph. For run 1 the utilization is steady at ~50 M bytes/s. For run 3 the steady utilization is doubled, around 100 M bytes/s.

From the cloudera blog post shared by DzOrd, you can see this important quote:

I’ve noticed that the HDFS client has trouble with tons of concurrent threads. A rough guess is that at most five tasks per executor can achieve full write throughput, so it’s good to keep the number of cores per executor below that number.

So, let's do a few calculations see what performance we expect if that is true.

Run 1: 19 GB, 7 cores, 3 executors

• 3 executors x 7 threads = 21 threads
• with 7 cores per executor, we expect limited IO to HDFS (maxes out at ~5 cores)
• effective throughput ~= 3 executors x 5 threads = 15 threads

Run 3: 4 GB, 2 cores, 12 executors

• 2 executors x 12 threads = 24 threads
• 2 cores per executor, so hdfs throughput is ok
• effective throughput ~= 12 executors x 2 threads = 24 threads

If the job is 100% limited by concurrency (the number of threads). We would expect runtime to be perfectly inversely correlated with the number of threads.

ratio_num_threads = nthread_job1 / nthread_job3 = 15/24 = 0.625
inv_ratio_runtime = 1/(duration_job1 / duration_job3) = 1/(50/31) = 31/50 = 0.62

So ratio_num_threads ~= inv_ratio_runtime, and it looks like we are network limited.

This same effect explains the difference between Run 1 and Run 2.

Run 2: 19 GB, 4 cores, 3 executors

• 3 executors x 4 threads = 12 threads
• with 4 cores per executor, ok IO to HDFS
• effective throughput ~= 3 executors x 4 threads = 12 threads

Comparing the number of effective threads and the runtime:

ratio_num_threads = nthread_job2 / nthread_job1 = 12/15 = 0.8
inv_ratio_runtime = 1/(duration_job2 / duration_job1) = 1/(55/50) = 50/55 = 0.91

It's not as perfect as the last comparison, but we still see a similar drop in performance when we lose threads.

Now for the last bit: why is it the case that we get better performance with more threads, esp. more threads than the number of CPUs?

A good explanation of the difference between parallelism (what we get by dividing up data onto multiple CPUs) and concurrency (what we get when we use multiple threads to do work on a single CPU) is provided in this great post by Rob Pike: Concurrency is not parallelism.

The short explanation is that if a Spark job is interacting with a file system or network the CPU spends a lot of time waiting on communication with those interfaces and not spending a lot of time actually "doing work". By giving those CPUs more than 1 task to work on at a time, they are spending less time waiting and more time working, and you see better performance.

If you don't like remembering SQL syntax, using Mig# you can simply:

var schema = new DbSchema(ConnectionString, DbPlatform.SqlServer2014);
schema.Alter(db => db.CreateTable("Customer")
     .WithPrimaryKeyColumn("Id", DbType.Int32).AsIdentity()
     .WithNotNullableColumn("First_Name", DbType.String).OfSize(50)
     .WithNotNullableColumn("Last_Name", DbType.String).OfSize(50)
     ...);

If you are not sure if it already exists, call DropIfExists before:

db.Tables["Customers"].DropIfExists();

You need to make it a generic method, like this:

public static T ConfigSetting<T>(string settingName)
{  
    return /* code to convert the setting to T... */
}

But the caller will have to specify the type they expect. You could then potentially use Convert.ChangeType, assuming that all the relevant types are supported:

public static T ConfigSetting<T>(string settingName)
{  
    object value = ConfigurationManager.AppSettings[settingName];
    return (T) Convert.ChangeType(value, typeof(T));
}

I'm not entirely convinced that all this is a good idea, mind you...

I just wanted to note here that Chrome also ignores page-break-* css settings in divs that have been floated.

I suspect there is a sound justification for this somewhere in the css spec, but I figured noting it might help someone someday ;-)

Just another note: IE7 can't acknowledge page break settings without an explicit height on the previous block element:

We monitor this from the application code, just to include the time required to establish/close the connection and transmit data across the network. It's pretty straight-forward...

Dim Duration as TimeSpan
Dim StartTime as DateTime = DateTime.Now

'Call the database here and execute your SQL statement

Duration = DateTime.Now.Subtract(StartTime)
Console.WriteLine(String.Format("Query took {0} seconds", Duration.TotalSeconds.ToString()))
Console.ReadLine()

Go to Windows--> Preference--->Java--->content assist--->Enable auto activation---(insert ._@abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ in auto activation triggers for java)

lsof -i tcp:port_number - will list the process running on that port

kill -9 PID - will kill the process

in your case, it will be

lsof -i tcp:3000 from your terminal find the PID of process

kill -9 PID

LINQ is the canonical example (for example, talking to a database), but in truth, any time you care more about expressing what to do, rather than actually doing it. For example, I use this approach in the RPC stack of protobuf-net (to avoid code-generation etc) - so you call a method with:

string result = client.Invoke(svc => svc.SomeMethod(arg1, arg2, ...));

This deconstructs the expression tree to resolve SomeMethod (and the value of each argument), performs the RPC call, updates any ref/out args, and returns the result from the remote call. This is only possible via the expression tree. I cover this more here.

Another example is when you are building the expression trees manually for the purpose of compiling to a lambda, as done by the generic operators code.

In my case the solutions above did not work I had to do the following:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(f)));

I finally found this link:

https://blogs.perficient.com/microsoft/2011/06/powershell-count-property-returns-nothing/

Well, it turns out that this is a quirk caused precisely because there was only one file in the directory. Some searching revealed that in this case, PowerShell returns a scalar object instead of an array. This object doesn’t have a count property, so there isn’t anything to retrieve.

The solution -- force PowerShell to return an array with the @ symbol:

Write-Host @( Get-ChildItem c:\MyFolder ).Count;

There is no best IDE. You make it as good as you get used using it.

@tvanfosson rocks with his answer.

However, I would suggest an improvement within js and a small controller check.

When we use @Url helper to call an action, we are going to receive a formatted html. It would be better to update the content (.html) not the actual element (.replaceWith).

More about at: What's the difference between jQuery's replaceWith() and html()?

$.get( '@Url.Action("details","user", new { id = Model.ID } )', function(data) {
    $('#detailsDiv').html(data);
}); 

This is specially useful in trees, where the content can be changed several times.

At the controller we can reuse the action depending on requester:

public ActionResult Details( int id )
{
    var model = GetFooModel();
    if (Request.IsAjaxRequest())
    {
        return PartialView( "UserDetails", model );
    }
    return View(model);
}

For Sybase the following works (with http://python-sybase.sourceforge.net)

import pandas.io.sql as psql
import Sybase

df = psql.frame_query("<Query>", con=Sybase.connect("<dsn>", "<user>", "<pwd>"))

You can do so by extending jQuerys functionality. This will shorten the amount of text you have to write for the selector.

$.extend($.expr[':'], {
        unchecked: function (obj) {
            return ((obj.type == 'checkbox' || obj.type == 'radio') && !$(obj).is(':checked'));
        }
    }
);

You can then use $("input:unchecked") to get all checkboxes and radio buttons that are checked.

To run the batch file when the VM user logs in:

Drag the shortcut--the one that's currently on your desktop--(or the batch file itself) to Start - All Programs - Startup. Now when you login as that user, it will launch the batch file.

Another way to do the same thing is to save the shortcut or the batch file in %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\.

As far as getting it to run full screen, it depends a bit what you mean. You can have it launch maximized by editing your batch file like this:

start "" /max "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" --comment "VM" --startvm "12dada4d-9cfd-4aa7-8353-20b4e455b3fa"

But if VirtualBox has a truly full-screen mode (where it hides even the taskbar), you'll have to look for a command-line parameter on VirtualBox.exe. I'm not familiar with that product.

Example

So, if we had a child element with an id of "child-element" and we wanted to get it's left/top position relative to a parent element, say a div that had a class of "item-parent", we'd use this code.

var position = $("#child-element").offsetRelative("div.item-parent");
alert('left: '+position.left+', top: '+position.top);

Plugin Finally, for the actual plugin (with a few notes expalaining what's going on):

// offsetRelative (or, if you prefer, positionRelative)
(function($){
    $.fn.offsetRelative = function(top){
        var $this = $(this);
        var $parent = $this.offsetParent();
        var offset = $this.position();
        if(!top) return offset; // Didn't pass a 'top' element 
        else if($parent.get(0).tagName == "BODY") return offset; // Reached top of document
        else if($(top,$parent).length) return offset; // Parent element contains the 'top' element we want the offset to be relative to 
        else if($parent[0] == $(top)[0]) return offset; // Reached the 'top' element we want the offset to be relative to 
        else { // Get parent's relative offset
            var parent_offset = $parent.offsetRelative(top);
            offset.top += parent_offset.top;
            offset.left += parent_offset.left;
            return offset;
        }
    };
    $.fn.positionRelative = function(top){
        return $(this).offsetRelative(top);
    };
}(jQuery));

Note : You can Use this on mouseClick or mouseover Event

$(this).offsetRelative("div.item-parent");

Remove element should clear out such errors. The reason behind this is the inherited settings. Your application will inherit some settings from its parent's config file and machine's (server) config files.
You can either remove such duplicates with the remove tag before adding them or make these tags non-inheritable in the upper level config files.

If you're writing GPLed code and using GNU autotools, then a portable way that takes care of the details on many OSes (including Windows and macOS) is gnulib's relocatable-prog module.

Here's a workaround for Binding Columns in the DataGrid. Since the Columns property is ReadOnly, like everyone noticed, I made an Attached Property called BindableColumns which updates the Columns in the DataGrid everytime the collection changes through the CollectionChanged event.

If we have this Collection of DataGridColumn's

public ObservableCollection<DataGridColumn> ColumnCollection
{
    get;
    private set;
}

Then we can bind BindableColumns to the ColumnCollection like this

<DataGrid Name="dataGrid"
          local:DataGridColumnsBehavior.BindableColumns="{Binding ColumnCollection}"
          AutoGenerateColumns="False"
          ...>

The Attached Property BindableColumns

public class DataGridColumnsBehavior
{
    public static readonly DependencyProperty BindableColumnsProperty =
        DependencyProperty.RegisterAttached("BindableColumns",
                                            typeof(ObservableCollection<DataGridColumn>),
                                            typeof(DataGridColumnsBehavior),
                                            new UIPropertyMetadata(null, BindableColumnsPropertyChanged));
    private static void BindableColumnsPropertyChanged(DependencyObject source, DependencyPropertyChangedEventArgs e)
    {
        DataGrid dataGrid = source as DataGrid;
        ObservableCollection<DataGridColumn> columns = e.NewValue as ObservableCollection<DataGridColumn>;
        dataGrid.Columns.Clear();
        if (columns == null)
        {
            return;
        }
        foreach (DataGridColumn column in columns)
        {
            dataGrid.Columns.Add(column);
        }
        columns.CollectionChanged += (sender, e2) =>
        {
            NotifyCollectionChangedEventArgs ne = e2 as NotifyCollectionChangedEventArgs;
            if (ne.Action == NotifyCollectionChangedAction.Reset)
            {
                dataGrid.Columns.Clear();
                foreach (DataGridColumn column in ne.NewItems)
                {
                    dataGrid.Columns.Add(column);
                }
            }
            else if (ne.Action == NotifyCollectionChangedAction.Add)
            {
                foreach (DataGridColumn column in ne.NewItems)
                {
                    dataGrid.Columns.Add(column);
                }
            }
            else if (ne.Action == NotifyCollectionChangedAction.Move)
            {
                dataGrid.Columns.Move(ne.OldStartingIndex, ne.NewStartingIndex);
            }
            else if (ne.Action == NotifyCollectionChangedAction.Remove)
            {
                foreach (DataGridColumn column in ne.OldItems)
                {
                    dataGrid.Columns.Remove(column);
                }
            }
            else if (ne.Action == NotifyCollectionChangedAction.Replace)
            {
                dataGrid.Columns[ne.NewStartingIndex] = ne.NewItems[0] as DataGridColumn;
            }
        };
    }
    public static void SetBindableColumns(DependencyObject element, ObservableCollection<DataGridColumn> value)
    {
        element.SetValue(BindableColumnsProperty, value);
    }
    public static ObservableCollection<DataGridColumn> GetBindableColumns(DependencyObject element)
    {
        return (ObservableCollection<DataGridColumn>)element.GetValue(BindableColumnsProperty);
    }
}

You can try something like this:

long x = somevalue;

double y = Double.longBitsToDouble(x);

If you have installed "react-native" globally then just open terminal/command line tool and type react-native -v you will get your answer.

And if you have installed "react-native" for a specific project then open terminal/command line tool and then navigate to your project and type react-native -v you will get your answer.

Issue is with remote server, can you login to the remote server and check if "scp" works

probable causes: - scp is not in path - openssh client not installed correctly

for more details http://www.linuxquestions.org/questions/linux-newbie-8/bash-scp-command-not-found-920513/

you can set Focus to a specific Cell by setting Selected property to true

dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;

to avoid Multiple Selection just set

dataGridView1.MultiSelect = false;

Android wifi ADB was earlier working on my IDE but after Updating Android Studio (my current is Android Studio 3.3) it is not working and always prompt as "Unable to connect to device......Same network"

After spending much time i was unbale to resolve the issue.

Then i tried - WIFI ADB ULTIMATE by

https://github.com/huazhouwang/WIFIADB/tree/master/WIFIADBIntelliJPlugin

It worked for me.

Working solution for me was first selecting the required text to edit and then using CTRL + F2 to select all matching data in the page. You may also use CTRL+Shift+L as suggested by @lesterCovax

Please Note: The above solution uses the inherent ability of VSCode editor to select similar text across the entire page, and therefore, be careful.

For me the above solution of Ctrl + ALT + Arrowkeys did not work as it caused the screen to change its display orientation against selecting the lines in VSCode.

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

Parse int is the tool you should use here, but like any tool it should be used correctly. When using parseInt you should always use the radix parameter to ensure the correct base is used

var currentValue = parseInt($("#replies").text(),10);

You are using the wrong parameters name, try:

if($_POST){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['text'];

//send email
    mail("[email protected]", "51 Deep comment from" .$email, $message);
}

git push origin amd_qlp_tester will work for you. If you just type git push, then the remote of the current branch is the default value.

Syntax of push looks like this - git push <remote> <branch>. If you look at your remote in .git/config file, you will see an entry [remote "origin"] which specifies url of the repository. So, in the first part of command you will tell Git where to find repository for this project, and then you just specify a branch.

Supported tags are: a, b, blockquote, br, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, img, li, ol, p, pre, small, span, strong, sub, sup, table, tcpdf, td, th, thead, tr, tt, u, ul

All the HTML attributes must be enclosed in double-quotes

Just another viewpoint. Performing an "or" in Prolog can also be done with the "disjunct" operator or semi-colon:

registered(X, Y) :-
    X = ct101; X = ct102; X = ct103.

For a fuller explanation:

Predicate control in Prolog

string result = arr.Aggregate("", (s, i) => s + i.ToString());

(Disclaimer: If you have a lot of digits (hundreds, at least) and you care about performance, I suggest eschewing this method and using a StringBuilder, as in JaredPar's answer.)

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

If you are using a virtual hosts configuration file, make sure the virtual host in question has the directive AllowOverride All somewhere like this:

<VirtualHost *:80>
        ...
    <Directory "directory/of/your/.htaccess">
        AllowOverride All
    </Directory>
</VirtualHost>

Basically, this states to allow processing of all .htaccess directives.

Generic types is a compile time abstraction. At runtime all maps will have the same type Map<Object, Object>. So if you are sure that values are strings, you can cheat on java compiler:

Map<String, Object> m1 = new HashMap<String, Object>();
Map<String, String> m2 = (Map) m1;

Copying keys and values from one collection to another is redundant. But this approach is still not good, because it violates generics type safety. May be you should reconsider your code to avoid such things.

For anyone looking how to do this in Kotlin DSL, here's a working example for build.gradle.kts:

tasks.register("bootRunDev") {
    group = "application"
    description = "Runs this project as a Spring Boot application with the dev profile"
    doFirst {
        tasks.bootRun.configure {
            systemProperty("spring.profiles.active", "dev")
        }
    }
    finalizedBy("bootRun")
}

An important point that the other answers forgot, is that "@keyword" is compiled into "keyword" in the CIL.

So if you have a framework that was made in, say, F#, which requires you to define a class with a property named "class", you can actually do it.

It is not that useful in practice, but not having it would prevent C# from some forms of language interop.

I usually see it used not for interop, but to avoid the keyword restrictions (usually on local variable names, where this is the only effect) ie.

private void Foo(){
   int @this = 2;
}

but I would strongly discourage that! Just find another name, even if the 'best' name for the variable is one of the reserved names.

You might want to use the Event Log ! Here's how to access it from C# http://support.microsoft.com/kb/307024/en

But whatever is the method that you will use, I'd recommend to output to a file every time something is appended to the log rather than when your process exits, so you won't lose data in the case of crash or if your process is killed.

Yess, possible with conditions:

If you have your app installed in the user phone and a server app communicating with this app, and there at last one of location service providers activated in the user phone, and some horrible android permissions!

In most of android phones there 3 location providers that can give exact location (GPS_PROVIDER 1m) or estimated (NETWORK_PROVIDER around 2-20m) and PASSIVE_PROVIDER (more in LocationManager official documentation).

1* App sends SMS to user's phone

Yess, can be server app or you create an android app if you want something automated, so you can do it manually by sending SMS from your default SMS app! I use Kannel: Open Source WAP and SMS Gateway and here (lot of APIs to send SMS )

2* App receives SMS at user's phone from the SMS sender

Yess, you can get all received SMS, and you can filter them by sender phone number! and do some actions when your specified sms received, basic tuto here (i do some actions according to the content of my SMS)

3* App gets location coordinates of the user's phone

Yess, you can get actual user coordinates easily if one of location providers is activated, so you can get last known location when the user have activated one of location providers, if those disabled or the phone don't have GPS hardware you can use Open Cell Id api to get the nearest cell coordinates(10m-10Km) or Loc8 api but those not available in all around the world, and some apps use IP location apis to get the country, city and province, here the simplest way to get current user location.

4* App sends location coordinates to the SMS sender via SMS

Yess, you can get sender phone number and send user location, immediately when SMS received or at specified times in the day.

(Those 4 yesses for you :) )

Viber and other apps that access to users locations, identify there users by there phone numbers by obligating them to send SMS to the server app to create an account and activate the free service (Ex:VOIP) , and lunch a service that can:

• Listen for location changes (GPS, Network or Cell Id)
• Send user location periodically(Ex: each 2 hours) or when user position changed!
• Stock user locations in file and create a map based on daily locations
• Receive SMS and update user location
• Receive server app commend and update user location
• Send events when user go inside or outside of a defined circle
• Listen for what user say and record it or open live voip call :s
• Maybe anything you think or u want to do :) !

And your application users must accept all of that when installing it, of corse i don't gonna install apps like this because i read permissions before installing :) and permissions maybe something like that:

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />    
<uses-permission android:name="android.permission.INTERNET" />
<-- and more if you wanna more -->

The final user will accept for something like that (those permissions of an android app u asked about):

This app has access to these permissions:

Your accounts -create accounts and set passwords -find accounts on the device -add or remove accounts -use accounts on the device -read Google service configuration

Your location -approximate location (network-based) -precise location (GPS and network-based)

Your messages -receive text messages (SMS) -send SMS messages -edit your text messages (SMS or MMS) -read your text messages (SMS or MMS)

Network communication -receive data from Internet -full network access -view Wi-Fi connections -view network connections -change network connectivity

Phone calls -read phone status and identity -directly call phone numbers

Storage -modify or delete the contents of your USB storage

Your applications information -retrieve running apps -close other apps -run at startup

Bluetooth -pair with Bluetooth devices -access Bluetooth settings

Camera -take pictures and videos

Other Application UI -draw over other apps

Microphone -record audio

Lock screen -disable your screen lock

Your social information -read your contacts -modify your contacts -read call log -write call log -read your social stream -write to your social stream

Development tools -read sensitive log data

System tools -modify system settings -send sticky broadcast -test access to protected storage

Affects battery -control vibration -prevent device from sleeping

Audio settings -change your audio settings

Sync Settings -read sync settings -toggle sync on and off -read sync statistics

Wallpaper -set wallpaper

# Method 1
f = open("Path/To/Your/File.txt", "w")   # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name)    # Write inside file 
f.close()                                # Close file 

# Method 2
with open("Path/To/Your/File.txt", "w") as f:   # Opens file and casts as f 
    f.write("Hello World form " + f.name)       # Writing
    # File closed automatically

There are many more methods but these two are most common. Hope this helped!

Adding on to the accepted answer. I ran into a similar problem and ended up using a user defined function that returned clob instead of varchar2. Here's my solution:

CREATE OR REPLACE TYPE temp_data FORCE AS OBJECT
(
    temporary_data NVARCHAR2(4000)
)
/

CREATE OR REPLACE TYPE temp_data_table FORCE AS TABLE OF temp_data;
/

CREATE OR REPLACE FUNCTION my_agg_func (p_temp_data_table IN temp_data_table, p_delimiter IN NVARCHAR2)
RETURN CLOB IS
  l_string CLOB;
BEGIN
  FOR i IN p_temp_data_table.FIRST .. p_temp_data_table.LAST LOOP
    IF i != p_temp_data_table.FIRST THEN
      l_string := l_string || p_delimiter;
    END IF;
    l_string := l_string || p_temp_data_table(i).temporary_data;
  END LOOP;
  RETURN l_string;
END my_agg_func;
/

Now, instead of doing

LISTAGG(column_to_aggregate, '#any_delimiter#') WITHIN GROUP (ORDER BY column_to_order_by)

I have to do this

my_agg_func (
    cast(
        collect(
            temp_data(column_to_aggregate)
            order by column_to_order_by
        ) as temp_data_table
    ),
    '#any_delimiter#'
)

Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).

The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.

Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).

For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.

data-interval="false"

Add this to the corresponding div ...

How about making a custom class containing an array, and use the array of your custom class.

UPDATED: Using prop instead of attr

 <input type="checkbox" name="vehicle" id="vehicleChkBox" value="FALSE"/>

 $('#vehicleChkBox').change(function(){
     cb = $(this);
     cb.val(cb.prop('checked'));
 });

OUT OF DATE:

Here is the jsfiddle

<input type="checkbox" name="vehicle" id="vehicleChkBox" value="FALSE" />

$('#vehicleChkBox').change(function(){
     if($(this).attr('checked')){
          $(this).val('TRUE');
     }else{
          $(this).val('FALSE');
     }
});

Thank you drifty0pine!

The first solution, it´s works!

[a relative link](../../some/dir/filename.md)
[Link to file in another dir on same drive](/another/dir/filename.md)
[Link to file in another dir on a different drive](/D:/dir/filename.md)

but I had need put more ../ until the folder where was my file, like this:

[FileToOpen](../../../../folderW/folderX/folderY/folderZ/FileToOpen.txt)

For a dictionary, you're best of encoding to JSON first. You can use simplejson.dumps() or if you want to convert from a data model in App Engine, you could use encode() from the GQLEncoder library.

Using Hex in Apache Commons:

String hexString = "fd00000aa8660b5b010006acdc0100000101000100010000";    
byte[] bytes = Hex.decodeHex(hexString.toCharArray());
System.out.println(new String(bytes, "UTF-8"));

A little more than was requsted but I use the extra timer code to track and alert if CPU usage is 90% or higher for a sustained period of 1 minute or longer.

public class Form1
{

    int totalHits = 0;

    public object getCPUCounter()
    {

        PerformanceCounter cpuCounter = new PerformanceCounter();
        cpuCounter.CategoryName = "Processor";
        cpuCounter.CounterName = "% Processor Time";
        cpuCounter.InstanceName = "_Total";

                     // will always start at 0
        dynamic firstValue = cpuCounter.NextValue();
        System.Threading.Thread.Sleep(1000);
                    // now matches task manager reading
        dynamic secondValue = cpuCounter.NextValue();

        return secondValue;

    }


    private void Timer1_Tick(Object sender, EventArgs e)
    {
        int cpuPercent = (int)getCPUCounter();
        if (cpuPercent >= 90)
        {
            totalHits = totalHits + 1;
            if (totalHits == 60)
            {
                Interaction.MsgBox("ALERT 90% usage for 1 minute");
                totalHits = 0;
            }                        
        }
        else
        {
            totalHits = 0;
        }
        Label1.Text = cpuPercent + " % CPU";
        //Label2.Text = getRAMCounter() + " RAM Free";
        Label3.Text = totalHits + " seconds over 20% usage";
    }
}

You can try this,

Step1: Override the Tabselected method in your activity

@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
    // When the given tab is selected, switch to the corresponding page in
    // the ViewPager.
    try {
    if(MyEventsFragment!=null && tab.getPosition()==3)
    {
        MyEvents.fragmentChanged();
    }
    }
    catch (Exception e)
    {

    }
    mViewPager.setCurrentItem(tab.getPosition());
}

Step 2: Using static method do what you want in your fragment,

public static void fragmentChanged()
{
    Toast.makeText(actvity, "Fragment Changed", Toast.LENGTH_SHORT).show();
}

I got it working with a call to something as simple as

function fb_login() {
  FB.login( function() {}, { scope: 'email,public_profile' } );
}

I don't know if facebook will ever be able to block this circumvention, but for now I can use whatever HTML or image I want to call fb_login and it works fine.

Not in CSS 2 as far as I'm aware. CSS 3 has more robust selectors but is not consistently implemented across all browsers. Even with the improved selectors, I don't believe it will accomplish exactly what you've specified in your example.

You can use SSH to create a tunnel and expose your container in your host.

You can do it in both ways, from container to host and from host to container. But you need a SSH tool like OpenSSH in both (client in one and server in another).

For example, in the container, you can do

$ yum install -y openssh openssh-server.x86_64
service sshd restart
Stopping sshd:                                             [FAILED]
Generating SSH2 RSA host key:                              [  OK  ]
Generating SSH1 RSA host key:                              [  OK  ]
Generating SSH2 DSA host key:                              [  OK  ]
Starting sshd:                                             [  OK  ]
$ passwd # You need to set a root password..

You can find the container IP address from this line (in the container):

$ ifconfig eth0 | grep "inet addr" | sed 's/^[^:]*:\([^ ]*\).*/\1/g'
172.17.0.2

Then in the host, you can just do:

sudo ssh -NfL 80:0.0.0.0:80 [email protected]

1.Go to "/Users/****/.gradle/wrapper/dists/gradle-.-all/*****".

2.Delete the "gradle-.-all.zip.lck" file.

3.Invalidate Cache and Restart.

What about using __proto__ for static methods?

function Foo(name){
  this.name = name
  Foo.__proto__.collection.push(this)
  Foo.__proto__.count++

}

Foo.__proto__.count=0
Foo.__proto__.collection=[]

var bar = new Foo('bar')
var baz = new Foo('baz')

Foo.count;//2
Foo.collection // [{...}, {...}]
bar.count // undefined

Download the Print.js from http://printjs.crabbly.com/

$http({
    url: "",
    method: "GET",
    headers: {
        "Content-type": "application/pdf"
    },
    responseType: "arraybuffer"
}).success(function (data, status, headers, config) {
    var pdfFile = new Blob([data], {
        type: "application/pdf"
    });
    var pdfUrl = URL.createObjectURL(pdfFile);
    //window.open(pdfUrl);
    printJS(pdfUrl);
    //var printwWindow = $window.open(pdfUrl);
    //printwWindow.print();
}).error(function (data, status, headers, config) {
    alert("Sorry, something went wrong")
});

Here you are:

let s = "hello Swift"
if let textRange = s.rangeOfString("Swift") {
    NSLog("exists")
}

Returning the new object fits with the REST principle of "Uniform Interface - Manipulation of resources through representations." The complete object is the representation of the new state of the object that was created.

There is a really excellent reference for API design, here: Best Practices for Designing a Pragmatic RESTful API

It includes an answer to your question here: Updates & creation should return a resource representation

It says:

To prevent an API consumer from having to hit the API again for an updated representation, have the API return the updated (or created) representation as part of the response.

Seems nicely pragmatic to me and it fits in with that REST principle I mentioned above.

Checkout the .SaveAs() method in Excel object.

wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)

Or following:

public static void SaveAs()
{
    Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass();
    Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);
    Microsoft.Office.Interop.Excel.Sheets wsSheet = wbWorkbook.Worksheets;
    Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];

    Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];

    thisCell.Value2 = "This is a test.";

    wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    wbWorkbook.SaveAs(@"c:\two.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

    wbWorkbook.Close(false, "", true);
}

If this is a simple Java project, You essentially create a new project and give the location of the existing code. The project wizard will tell you that it will use existing sources.

Also, Eclipse 3.3.2 is ancient history, you guys should really upgrade. This is like using Visual Studio 5.

ActiveModel::Dirty didn't work for me because the @model.update_attributes() hid the changes. So this is how I detected changes it in an update method in a controller:

def update
  @model = Model.find(params[:id])
  detect_changes

  if @model.update_attributes(params[:model])
    do_stuff if attr_changed?
  end
end

private

def detect_changes
  @changed = []
  @changed << :attr if @model.attr != params[:model][:attr]
end

def attr_changed?
  @changed.include :attr
end

If you're trying to detect a lot of attribute changes it could get messy though. Probably shouldn't do this in a controller, but meh.

      link: function (scope, element, attr, ctrl) {
        function inputValue(val) {

 });

I had the same problem and I found this is working:

if ($("#deliveryNext").attr('disabled')) {
  // do sth if disabled
} else {
  // do sth if enabled 
}

If this gives you undefined then you can use if condition also.

When you evaluate undefined it will return false.

The installer from the git homepage installs into /usr/local/git by default. See also this answer. However, if you install XCode4, it will install a git version in /usr/bin. To ensure you can easily upgrade from the website and use the latest git version, edit either your profile information to place /usr/local/git/bin before /usr/bin in the $PATH or edit /etc/paths and insert /usr/local/git/bin as the first entry (see this answer).

You are doing everything right, except passing your bundle path to asset() function.

According to documentation - in your example this should look like below:

{{ asset('bundles/webshome/css/main.css') }}

Tip: you also can call assets:install with --symlink key, so it will create symlinks in web folder. This is extremely useful when you often apply js or css changes (in this way your changes, applied to src/YouBundle/Resources/public will be immediately reflected in web folder without need to call assets:install again):

app/console assets:install web --symlink

Also, if you wish to add some assets in your child template, you could call parent() method for the Twig block. In your case it would be like this:

{% block stylesheets %}
    {{ parent() }}

    <link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}

       this.setState(
        {
            originId: input.originId,
            destinationId: input.destinationId,
            radius: input.radius,
            search: input.search
        },
        function() { console.log("setState completed", this.state) }
       )

this might be helpful

You've almost got it. Tell jquery you want to load only the script:

$("#myBtn").click(function() {
    $("#myDiv").load("trackingCode.html script");
});

1. Declare your jQuery between <script> and </script> in the <head>,
2. Wrap your .scroll() event within

$(document).ready(function(){
  //do something
});

I know this is an older question, but for reference, a really simple way for formatting dates without any data annotations or any other settings is as follows:

@Html.TextBoxFor(m => m.StartDate, new { @Value = Model.StartDate.ToString("dd-MMM-yyyy") })

The above format can of course be changed to whatever.

SELECT rest.field1
FROM mastertable as m
INNER JOIN table1 at t1 on t1.field1 = m.field
INNER JOIN table2 at t2 on t2.field = t1.field
WHERE t1.field3 = (SELECT MAX(field3) FROM table1)

Using the stat.* bit masks does seem to me the most portable and explicit way of doing this. But on the other hand, I often forget how best to handle that. So, here's an example of masking out the 'group' and 'other' permissions and leaving 'owner' permissions untouched. Using bitmasks and subtraction is a useful pattern.

import os
import stat
def chmodme(pn):
    """Removes 'group' and 'other' perms. Doesn't touch 'owner' perms."""
    mode = os.stat(pn).st_mode
    mode -= (mode & (stat.S_IRWXG | stat.S_IRWXO))
    os.chmod(pn, mode)

Like this

#if defined(LINUX) || defined(ANDROID)

I have just realized that my error was caused in the naming convention of my property file. When i used xxxx.xxxx.properties i got the error:

java.util.MissingResourceException: Can't find bundle for base name 'property_file name', locale en_US

Changing it to something like xxx-xxxx.properties works like a charm. Hope i help someone!

I removed the tag in the .project .

    <buildCommand>
        <name>org.eclipse.wst.jsdt.core.javascriptValidator</name>
        <arguments>
        </arguments>
    </buildCommand>

It's worked very well for me.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

So maybe you want to have this in your index.html to load the library, script, and initialize the app with a view:

<html>
  <body ng-app="yourApp">
    <div class="span12">
      <div ng-view=""></div>
    </div>
    <script src="http://code.angularjs.org/1.2.0-rc.2/angular.js"></script>
    <script src="script.js"></script>
  </body>
</html>

Then yourView.html could just be:

<div>
  <h1>{{ stuff.h1 }}</h1>
  <p>{{ stuff.content }}</p>
</div>

scripts.js could have your controller with data $scope'd to it.

angular.module('yourApp')
    .controller('YourCtrl', function ($scope) {
      $scope.stuff = {
        'h1':'Title',
        'content':"A paragraph..."
      };
    });

Lastly, you'll have to config routes and assign the controller to view for it's $scope (i.e. your data object)

angular.module('yourApp', [])
.config(function ($routeProvider) {
  $routeProvider
    .when('/', {
      templateUrl: 'views/yourView.html',
      controller: 'YourCtrl'
    });
});

I haven't tested this, sorry if there's a bug but I think this is the Angularish way to get data

this is output of this program

Scanner s=new Scanner (System.in);
int row, elem, col;

Systm.out.println("Enter Element to insert");
elem = s.nextInt();
System.out.println("Enter row");
row=s.nextInt();
System.out.println("Enter row");
col=s.nextInt();
for (int c=row-1; c < row; c++)
{
    for (d = col-1 ; d < col ; d++)
         array[c][d] = elem;
}
for(c = 0; c < size; c++)
{ 
   for (d = 0 ; d < size ; d++)
         System.out.print( array[c] [d] +"   ");
   System.out.println();
}

It could also be that you have a python3 system only. You therefore have installed the necessary packages via pip3 install , like pip3 install wheel.

You'll need to build your stuff using python3 specifically.

python3 setup.py sdist
python3 setup.py bdist_wheel

Cheers.

document.getElementById('myDiv').style.height = 500;

This is the very basic JS code required to adjust the height of your object dynamically. I just did this very thing where I had some auto height property, but when I add some content via XMLHttpRequest I needed to resize my parent div and this offsetheight property did the trick in IE6/7 and FF3

From http://developer.android.com/reference/android/app/Activity.html

public final void showDialog (int id) Added in API level 1

This method was deprecated in API level 13. Use the new DialogFragment class with FragmentManager instead; this is also available on older platforms through the Android compatibility package.

Simple version of showDialog(int, Bundle) that does not take any arguments. Simply calls showDialog(int, Bundle) with null arguments.

Why

• A fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog.
• Here is a nice discussion Android DialogFragment vs Dialog
• Another nice discussion DialogFragment advantages over AlertDialog

I have just came from solving this problem on and I would like to share the complete code that can download, save to the sdcard (and hide the filename) and retrieve the images and finally it checks if the image is already there. The url comes from the database so the filename can be uniquely easily using id.

first download images

   private class GetImages extends AsyncTask<Object, Object, Object> {
    private String requestUrl, imagename_;
    private ImageView view;
    private Bitmap bitmap ; 
      private FileOutputStream fos;
    private GetImages(String requestUrl, ImageView view, String _imagename_) {
        this.requestUrl = requestUrl;
        this.view = view;
        this.imagename_ = _imagename_ ;
    }

    @Override
    protected Object doInBackground(Object... objects) {
        try {
            URL url = new URL(requestUrl);
            URLConnection conn = url.openConnection();
            bitmap = BitmapFactory.decodeStream(conn.getInputStream());
        } catch (Exception ex) {
        }
        return null;
    }

    @Override
    protected void onPostExecute(Object o) { 
        if(!ImageStorage.checkifImageExists(imagename_))
        { 
                view.setImageBitmap(bitmap);
                ImageStorage.saveToSdCard(bitmap, imagename_); 
            }  
        }  
   }

Then create a class for saving and retrieving the files

  public class ImageStorage {


public static String saveToSdCard(Bitmap bitmap, String filename) {

    String stored = null;

    File sdcard = Environment.getExternalStorageDirectory() ; 

    File folder = new File(sdcard.getAbsoluteFile(), ".your_specific_directory");//the dot makes this directory hidden to the user
    folder.mkdir(); 
    File file = new File(folder.getAbsoluteFile(), filename + ".jpg") ;
    if (file.exists())
        return stored ;

    try {
        FileOutputStream out = new FileOutputStream(file);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
        out.flush();
        out.close();
        stored = "success";
    } catch (Exception e) {
        e.printStackTrace();
    }
     return stored;
   }

public static File getImage(String imagename) {

        File mediaImage = null;
        try {
            String root = Environment.getExternalStorageDirectory().toString();
            File myDir = new File(root);
            if (!myDir.exists())
                return null;

            mediaImage = new File(myDir.getPath() + "/.your_specific_directory/"+imagename);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return mediaImage;
    }
public static boolean checkifImageExists(String imagename)
{
    Bitmap b = null ;
    File file = ImageStorage.getImage("/"+imagename+".jpg");
    String path = file.getAbsolutePath();

    if (path != null)
        b = BitmapFactory.decodeFile(path); 

    if(b == null ||  b.equals(""))
    {
        return false ;
    }
    return true ;
}
  }

Then To access the images first check if it is already there if not then download

          if(ImageStorage.checkifImageExists(imagename))
            {
                File file = ImageStorage.getImage("/"+imagename+".jpg"); 
                String path = file.getAbsolutePath(); 
                if (path != null){
                    b = BitmapFactory.decodeFile(path);
                    imageView.setImageBitmap(b);
                }  
            } else { 
                new GetImages(imgurl, imageView, imagename).execute() ; 
            }

Reading input from keyboard is analogous to downloading files from the internet, the java io system opens connections with the source of data to be read using InputStream or Reader, you have to handle a situation where the connection can break by using IOExceptions

If you want to know exactly what it means to work with InputStreams and BufferedReader this video shows it

// Simplest way

var originalContent = $('select').html();

$('select').change(function() {
    $('select').html(originalContent); //Restore Original Content
    $('select option[myfilter=1]').remove(); // Filter my options
});

The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

Just copy this code to all components that you will drag.

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

example:

<TextView
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    android:text="To:"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    tools:layout_editor_absoluteX="7dp"
    tools:layout_editor_absoluteY="4dp"
    android:id="@+id/textTo"/>

I had to do something similar to Sean and ilalex's answer.
But I had too many options to explicitly define the sort order for and only needed to float certain entries to the front of the list ... in the specified (non-natural) order.
Hopefully this is helpful to someone else.

public class CarComparator implements Comparator<Car> {

    //sort these items in this order to the front of the list 
    private static List<String> ORDER = Arrays.asList("dd", "aa", "cc", "bb");

    public int compare(final Car o1, final Car o2) {
        int result = 0;
        int o1Index = ORDER.indexOf(o1.getName());
        int o2Index = ORDER.indexOf(o2.getName());
        //if neither are found in the order list, then do natural sort
        //if only one is found in the order list, float it above the other
        //if both are found in the order list, then do the index compare
        if (o1Index < 0 && o2Index < 0) result = o1.getName().compareTo(o2.getName());
        else if (o1Index < 0) result = 1;
        else if (o2Index < 0) result = -1;
        else result = o1Index - o2Index;
        return result;
    }

//Testing output: dd,aa,aa,cc,bb,bb,bb,a,aaa,ac,ac,ba,bd,ca,cb,cb,cd,da,db,dc,zz
}

The RegExp constructor creates a regular expression object for matching text with a pattern.

    var pattern1 = ':\\(|:=\\(|:-\\(';
    var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';
    var regex = new RegExp(pattern1 + '|' + pattern2, 'gi');
    str.match(regex);

Above code works perfectly for me...

Interesting. How are you generating your JSON on the server end? Are you using a library function (such as json_encode in PHP), or are you building the JSON string by hand?

The only thing that grabs my attention is the escape apostrophe (\'). Seeing as you're using double quotes, as you indeed should, there is no need to escape single quotes. I can't check if that is indeed the cause for your jQuery error, as I haven't updated to version 1.4.1 myself yet.

Another option:

Replace the string delimiter with a single character, then split on that character.

string input = "abc][rfd][5][,][.";
string[] parts1 = input.Replace("][","-").Split('-');

Let's assume an 8 bit computer with 8 bit addresses (and thus only 256 bytes of memory). This is part of that memory (the numbers at the top are the addresses):

  54   55   56   57   58   59   60   61   62   63   64   65   66   67   68   69
+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+
|    | 58 |    |    | 63 |    | 55 |    |    | h  | e  | l  | l  | o  | \0 |    |
+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+----+

What you can see here, is that at address 63 the string "hello" starts. So in this case, if this is the only occurrence of "hello" in memory then,

const char *c = "hello";

... defines c to be a pointer to the (read-only) string "hello", and thus contains the value 63. c must itself be stored somewhere: in the example above at location 58. Of course we can not only point to characters, but also to other pointers. E.g.:

const char **cp = &c;

Now cp points to c, that is, it contains the address of c (which is 58). We can go even further. Consider:

const char ***cpp = &cp;

Now cpp stores the address of cp. So it has value 55 (based on the example above), and you guessed it: it is itself stored at address 60.

As to why one uses pointers to pointers:

• The name of an array usually yields the address of its first element. So if the array contains elements of type t, a reference to the array has type t *. Now consider an array of arrays of type t: naturally a reference to this 2D array will have type (t *)* = t **, and is hence a pointer to a pointer.
• Even though an array of strings sounds one-dimensional, it is in fact two-dimensional, since strings are character arrays. Hence: char **.
• A function f will need to accept an argument of type t ** if it is to alter a variable of type t *.
• Many other reasons that are too numerous to list here.

try something like this

echo "yours ip addresses are:"
ifconfig | grep "inet addr" | cut -d':' -f2 | cut -d' ' -f1

linux like systems

put this inside your Manifest like this in No fullscreen Mode

android:windowSoftInputMode="stateVisible|adjustPan" 

in your manifest

<activity
    android:windowSoftInputMode="stateVisible|adjustPan"
    android:name="com.example.patronusgps.MainActivity"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Yes, you understood correctly. CountDownLatch works in latch principle, the main thread will wait until the gate is open. One thread waits for n threads, specified while creating the CountDownLatch.

Any thread, usually the main thread of the application, which calls CountDownLatch.await() will wait until count reaches zero or it's interrupted by another thread. All other threads are required to count down by calling CountDownLatch.countDown() once they are completed or ready.

As soon as count reaches zero, the waiting thread continues. One of the disadvantages/advantages of CountDownLatch is that it's not reusable: once count reaches zero you cannot use CountDownLatch any more.

Edit:

Use CountDownLatch when one thread (like the main thread) requires to wait for one or more threads to complete, before it can continue processing.

A classical example of using CountDownLatch in Java is a server side core Java application which uses services architecture, where multiple services are provided by multiple threads and the application cannot start processing until all services have started successfully.

P.S. OP's question has a pretty straightforward example so I didn't include one.

Swift 3, iOS 10

func call(phoneNumber:String) {
        let cleanPhoneNumber = phoneNumber.components(separatedBy: CharacterSet.decimalDigits.inverted).joined(separator: "")
        let urlString:String = "tel://\(cleanPhoneNumber)"
        if let phoneCallURL = URL(string: urlString) {
            if (UIApplication.shared.canOpenURL(phoneCallURL)) {
                UIApplication.shared.open(phoneCallURL, options: [:], completionHandler: nil)
            }
        }
  }

   .disabled{ pointer-events: none }

will disable the click event, but not the tab event. To disable the tab event, you can set the tabindex to -1 if the disable flag is true.

<li [routerLinkActive]="['active']" [class.disabled]="isDisabled">
     <a [routerLink]="['link']" tabindex="{{isDisabled?-1:0}}" > Menu Item</a>
</li>

Both the field name and the value should be url encoded. format of the post data and query string are the same

The .net way of doing is something like this

NameValueCollection outgoingQueryString = HttpUtility.ParseQueryString(String.Empty);
outgoingQueryString.Add("field1","value1");
outgoingQueryString.Add("field2", "value2");
string postdata = outgoingQueryString.ToString();

This will take care of encoding the fields and the value names

Thanks to RandomUs 1r for this observation:

changing it to display:inline-block; solves that issue. – RandomUs1r May 14 '13 at 21:59

I tried it myself for a top navigation menu bar, as follows:

First style the "li" element as follows:

display: inline-block;
width: 7em;
text-align: center;

Then style the "a"> element as follows:

width: 100%;

Now the navigation links are all equal width with text centered in each link.

You can use the -as operator. If casting succeed you get back a number:

$numberAsString -as [int]

you could put the style in container div menu with:

<div style="position:relative; z-index:10">
   ...
   <!--html menu-->
   ...
</div>

Given

• asyncFn function
• array of items

Required

• promise chaining .then()'s in series (in order)
• native es6

Solution

let asyncFn = (item) => {
  return new Promise((resolve, reject) => {
    setTimeout( () => {console.log(item); resolve(true)}, 1000 )
  })
}

// asyncFn('a')
// .then(()=>{return async('b')})
// .then(()=>{return async('c')})
// .then(()=>{return async('d')})

let a = ['a','b','c','d']

a.reduce((previous, current, index, array) => {
  return previous                                    // initiates the promise chain
  .then(()=>{return asyncFn(array[index])})      //adds .then() promise for each item
}, Promise.resolve())

Query to add column with comment are :

alter table table_name 
add( "NISFLAG"    NUMBER(1,0) )

comment on column "ELIXIR"."PRD_INFO_1"."NISPRODGSTAPPL" is 'comment here'

commit;

Or you can do like this:

your_df.to_excel( r'C:\Users\full_path\excel_name.xlsx',
                  sheet_name= 'your_sheet_name'
                )

I just find this solution but in my case it doesn't work:

@OneToMany(cascade = CascadeType.ALL, targetEntity = MyClass.class, mappedBy = "xxx", fetch = FetchType.LAZY, orphanRemoval = true) 

orphanRemoval = true has no effect.

put display:block on the anchor element. and/or zoom:1;

but you should just really do this.

a#parentdivimage{position:relative; width:184px; height:235px; 
                 border:2px solid #000; text-align:center; 
                 background-image:url("myimage.jpg"); 
                 background-position: 50% 50%; 
                 background-repeat:no-repeat; display:block; 
                 text-indent:-9999px}

<a id="parentdivimage">whatever your alt attribute was</a>

Before we try to solve the invalid character problem, the lack of curly braces around the if and else if statements is wreaking havoc on your program's logic. Change it to this:

if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}
else 
     System.out.println("Invalid user input.");

Much clearer! It's now actually a piece of cake to catch the bad characters. You need to move the else statement to somewhere that will catch the errors before you attempt to process anything else. So change everything to:

if( /* insert your check for bad characters here */ ) { 
     System.out.println("Invalid user input.");
}
else if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}

also put (main/assets/htmls/name.gif) [with this html adjust to the size]

<html style="margin: 0;">
<body style="margin: 0;">
<img src="name.gif" style="width: 100%; height: 100%" />
</body>
</html>

declare in your Xml for example like this (main/res/layout/name.xml): [you define the size, for example]

<WebView
android:layout_width="70dp"
android:layout_height="70dp"
android:id="@+id/webView"
android:layout_gravity="center_horizontal" />

in your Activity put the next code inside of onCreate

web = (WebView) findViewById(R.id.webView); 
web.setBackgroundColor(Color.TRANSPARENT); //for gif without background
web.loadUrl("file:///android_asset/htmls/name.html");

if you want load dynamically you have to load the webview with data:

// or "[path]/name.gif" (e.g: file:///android_asset/name.gif for resources in asset folder), and in loadDataWithBaseURL(), you don't need to set base URL, on the other hand, it's similar to loadData() method.
String gifName = "name.gif";
String yourData = "<html style=\"margin: 0;\">\n" +
        "    <body style=\"margin: 0;\">\n" +
        "    <img src=" + gifName + " style=\"width: 100%; height: 100%\" />\n" +
        "    </body>\n" +
        "    </html>";
// Important to add this attribute to webView to get resource from outside.
webView.getSettings().setAllowFileAccess(true);

// Notice: should use loadDataWithBaseURL. BaseUrl could be the base url such as the path to asset folder, or SDCard or any other path, where your images or the other media resides related to your html
webView.loadDataWithBaseURL("file:///android_asset/", yourData, "text/html", "utf-8", null);
// Or if you want to load image from SD card or where else, here is the idea.
String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
webView.loadDataWithBaseURL(base + '/', yourData, "text/html", "utf-8", null);

suggestion: is better load gif with static images for more information check https://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

That's it, I hope you help.

As can be seen from previous posts, one can argue that if class functionality needs to be circumvented then something is wrong in the class architecture. That might be true, but one cannot always restructure or refactor the class structure on a large mature project. The various levels of change management might be one problem, but to keep existing functionality operating the same after refactoring is not always a trivial task, especially if time constraints apply. On a mature project it can be quite an undertaking to keep various regression tests from passing after a code restructure; there are often obscure "oddities" that show up. We had a similar problem in some cases inherited functionality should not execute (or should perform something else). The approach we followed below, was to put the base code that need to be excluded in a separate virtual function. This function can then be overridden in the derived class and the functionality excluded or altered. In this example "Text 2" can be prevented from output in the derived class.

public class Base
{
    public virtual void Foo()
    {
        Console.WriteLine("Hello from Base");
    }
}

public class Derived : Base
{
    public override void Foo()
    {
        base.Foo();
        Console.WriteLine("Text 1");
        WriteText2Func();
        Console.WriteLine("Text 3");
    }

    protected virtual void WriteText2Func()
    {  
        Console.WriteLine("Text 2");  
    }
}

public class Special : Derived
{
    public override void WriteText2Func()
    {
        //WriteText2Func will write nothing when 
        //method Foo is called from class Special.
        //Also it can be modified to do something else.
    }
}

Were I you I would do something like this:

Before doing anything please keep a copy (better safe than sorry)

git checkout master
git checkout -b temp 
git reset --hard <sha-1 of your first commit> 
git add .
git commit -m 'Squash all commits in single one'
git push origin temp

After doing that you can delete other branches.

Result: You are going to have a branch with only 2 commits.

Use git log --oneline to see your commits in a minimalistic way and to find SHA-1 for commits!

Isn't this exactly what squashing a rebase does? Just squash everything except the last commit and then (force) push it.

I've had my drivers installed and the Arduino connected through an unpowered usb hub. Moving it to an USB port of my computer made it work.

You can use the following:

plt.hold(True)

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

@RequestBody : Annotation indicating a method parameter should be bound to the body of the HTTP request.

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public void handle(@RequestBody String body, Writer writer) throws IOException {
    writer.write(body);
}

@ResponseBody annotation can be put on a method and indicates that the return type should be written straight to the HTTP response body (and not placed in a Model, or interpreted as a view name).

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public  @ResponseBody String helloWorld() {
    return "Hello World";
}  

Alternatively, we can use @RestController annotation in place of @Controller annotation. This will remove the need to using @ResponseBody.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

Strings in Python are immutable meaning you cannot replace parts of them.

You can however create a new string that is modified. Mind that this is not semantically equivalent since other references to the old string will not be updated.

You could for instance write a function:

def replace_str_index(text,index=0,replacement=''):
    return '%s%s%s'%(text[:index],replacement,text[index+1:])

And then for instance call it with:

new_string = replace_str_index(old_string,middle)

If you do not feed a replacement, the new string will not contain the character you want to remove, you can feed it a string of arbitrary length.

For instance:

replace_str_index('hello?bye',5)

will return 'hellobye'; and:

replace_str_index('hello?bye',5,'good')

will return 'hellogoodbye'.

As mentioned, try to kill ipython notebook processes properly by first going to the "running" tab in your ipynb/jupyter browser session, and then check open terminals on your console and shut down with ctrl-c. The latter should be avoided if possible.

If you run an ipython notebook list and continue to see running ipython servers at different ports, make note of which ports the existing notebooks are being served to. Then shut down your TCP ports:

fuser -k 'port#'/tcp 

I'm not sure if there are other risks involved with doing this. If so, let me know.

I don't think that you need to use each(), you can use standard for loop

var children = $element.children().not(".pb-sortable-placeholder");
for (var i = 0; i < children.length; i++) {
    var currentChild = children.eq(i);
    // whatever logic you want
    var oldPosition = currentChild.data("position");
}

this way you can have the standard for loop features like break and continue works by default

also, the debugging will be easier

 <style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">@color/colorAccent</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">@color/teal</item>
</style>





new AlertDialog.Builder(new ContextThemeWrapper(context,R.style.AlertDialogCustom))
            .setMessage(Html.fromHtml(Msg))
            .setPositiveButton(posBtn, okListener)
            .setNegativeButton(negBtn, null)
            .create()
            .show();

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

$(".overdue").each( function() {
    alert("Your book is overdue.");
});

Note that ".addClass()" works because addClass is a function defined on the jQuery object. You can't just plop any old function on the end of a selector and expect it to work.

Also, probably a bad idea to bombard the user with n popups (where n = the number of books overdue).

Perhaps use the size function:

alert( "You have " + $(".overdue").size() + " books overdue." );

I came across this error message through a silly mistake. A classic example of Python giving you plenty of room to make a fool of yourself. Observe:

class DOH(object):
def __init__(self, property=None):
    self.property=property

def property():
    return property

x = DOH(1)
print(x.property())

Results

$ python3 t.py
Traceback (most recent call last):
  File "t.py", line 9, in <module>
    print(x.property())
TypeError: 'int' object is not callable

The problem here of course is that the function is overwritten with a property.

I created one more list by sorting Jaspers list by device RAM (I made my own tests with Split's tool and fixed some results - check my comments in Jaspers thread).

device RAM: percent range to crash

• 256MB: 49% - 51%
• 512MB: 53% - 63%
• 1024MB: 57% - 68%
• 2048MB: 68% - 69%
• 3072MB: 63% - 66%
• 4096MB: 77%
• 6144MB: 81%

Special cases:

• iPhone X (3072MB): 50%
• iPhone XS/XS Max (4096MB): 55%
• iPhone XR (3072MB): 63%
• iPhone 11/11 Pro Max (4096MB): 54% - 55%

Device RAM can be read easily:

[NSProcessInfo processInfo].physicalMemory

From my experience it is safe to use 45% for 1GB devices, 50% for 2/3GB devices and 55% for 4GB devices. Percent for macOS can be a bit bigger.

In addition to accepted answer, I would like to propose one more wider solution that can find a 2D set difference of two dataframes with any index/columns (they might not coincide for both datarames). Also method allows to setup tolerance for float elements for dataframe comparison (it uses np.isclose)

import numpy as np
import pandas as pd

def get_dataframe_setdiff2d(df_new: pd.DataFrame, 
                            df_old: pd.DataFrame, 
                            rtol=1e-03, atol=1e-05) -> pd.DataFrame:
    """Returns set difference of two pandas DataFrames"""

    union_index = np.union1d(df_new.index, df_old.index)
    union_columns = np.union1d(df_new.columns, df_old.columns)

    new = df_new.reindex(index=union_index, columns=union_columns)
    old = df_old.reindex(index=union_index, columns=union_columns)

    mask_diff = ~np.isclose(new, old, rtol, atol)

    df_bool = pd.DataFrame(mask_diff, union_index, union_columns)

    df_diff = pd.concat([new[df_bool].stack(),
                         old[df_bool].stack()], axis=1)

    df_diff.columns = ["New", "Old"]

    return df_diff

Example:

In [1]

df1 = pd.DataFrame({'A':[2,1,2],'C':[2,1,2]})
df2 = pd.DataFrame({'A':[1,1],'B':[1,1]})

print("df1:\n", df1, "\n")

print("df2:\n", df2, "\n")

diff = get_dataframe_setdiff2d(df1, df2)

print("diff:\n", diff, "\n")

Out [1]

df1:
   A  C
0  2  2
1  1  1
2  2  2 

df2:
   A  B
0  1  1
1  1  1 

diff:
     New  Old
0 A  2.0  1.0
  B  NaN  1.0
  C  2.0  NaN
1 B  NaN  1.0
  C  1.0  NaN
2 A  2.0  NaN
  C  2.0  NaN 

You can make use of System#nanoTime(). Get it before and after the execution and just do the math. It's preferred above System#currentTimeMillis() because it has a better precision. Depending on the hardware and the platform used, you may otherwise get an incorrect gap in elapsed time. Here with Core2Duo on Windows, between about 0 and ~15ms actually nothing can be calculated.

A more advanced tool is a profiler.

This example shows how to use a list of multiprocessing.Pipe instances to return strings from an arbitrary number of processes:

import multiprocessing

def worker(procnum, send_end):
    '''worker function'''
    result = str(procnum) + ' represent!'
    print result
    send_end.send(result)

def main():
    jobs = []
    pipe_list = []
    for i in range(5):
        recv_end, send_end = multiprocessing.Pipe(False)
        p = multiprocessing.Process(target=worker, args=(i, send_end))
        jobs.append(p)
        pipe_list.append(recv_end)
        p.start()

    for proc in jobs:
        proc.join()
    result_list = [x.recv() for x in pipe_list]
    print result_list

if __name__ == '__main__':
    main()

Output:

0 represent!
1 represent!
2 represent!
3 represent!
4 represent!
['0 represent!', '1 represent!', '2 represent!', '3 represent!', '4 represent!']

This solution uses fewer resources than a multiprocessing.Queue which uses

• a Pipe
• at least one Lock
• a buffer
• a thread

or a multiprocessing.SimpleQueue which uses

• a Pipe
• at least one Lock

It is very instructive to look at the source for each of these types.

It means there is an extension=... or zend_extension=... line in one of your php configuration files (php.ini, or another close to it) that is trying to load that extension : ixed.5.2.lin

Unfortunately that file or path doesn't exist or the permissions are incorrect.

1. Try to search in the .ini files that are loaded by PHP (phpinfo() can indicate which ones are) - one of them should try to load that extension.
2. Either correct the path to the file or comment out the corresponding line.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

On MacOS: add source ~/.bash_profile to the end of ~/.zshrc. Then this profile will be in effect when you open zsh.

I use the following aliases.

[alias]
    lol = log --graph --decorate --pretty=oneline --abbrev-commit
    lola = log --graph --decorate --pretty=oneline --abbrev-commit --all

It has more info in the color scheme than aliases that I saw above. It also seems to be quite common, so you might have a chance of it existing in other's environment or being able to mention it in conversation without having to explain it.

The __repr__ method simply tells Python how to print objects of a class

Short answer:

As written in xsd:

<xs:attribute name="minOccurs" type="xs:nonNegativeInteger" use="optional" default="1"/>
<xs:attribute name="maxOccurs" type="xs:allNNI" use="optional" default="1"/>

If you provide an attribute with number, then the number is boundary. Otherwise attribute should appear exactly once.

There's an easy way to produce this error:

    $joe = null;
    $joe->anything();

Will render the error:

Fatal error: Call to a member function anything() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/casMail/dao/server.php on line 23

It would be a lot better if PHP would just say,

Fatal error: Call from Joe is not defined because (a) joe is null or (b) joe does not define anything() in on line <##>.

Usually you have build your class so that $joe is not defined in the constructor or

Maybe jQuery UI does what you are looking for. Its composed out of many handy helper functions like making objects draggable, droppable, resizable, sortable etc.

Take a look at sortable with connected lists.

public static void main(String[] args) {

try {

    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    Document doc = docBuilder.newDocument();
    Element rootElement = doc.createElement("CONFIGURATION");
    doc.appendChild(rootElement);
    Element browser = doc.createElement("BROWSER");
    browser.appendChild(doc.createTextNode("chrome"));
    rootElement.appendChild(browser);
    Element base = doc.createElement("BASE");
    base.appendChild(doc.createTextNode("http:fut"));
    rootElement.appendChild(base);
    Element employee = doc.createElement("EMPLOYEE");
    rootElement.appendChild(employee);
    Element empName = doc.createElement("EMP_NAME");
    empName.appendChild(doc.createTextNode("Anhorn, Irene"));
    employee.appendChild(empName);
    Element actDate = doc.createElement("ACT_DATE");
    actDate.appendChild(doc.createTextNode("20131201"));
    employee.appendChild(actDate);
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);
    StreamResult result = new StreamResult(new File("/Users/myXml/ScoreDetail.xml"));
    transformer.transform(source, result);
    System.out.println("File saved!");
  } catch (ParserConfigurationException pce) {
    pce.printStackTrace();
  } catch (TransformerException tfe) {
    tfe.printStackTrace();}}

Let's say you have a button with the text, "Click Me". What width should that button be?

First, you definitely don't want the button to be smaller than the text. Otherwise, the text would be clipped. This is the horizontal compression resistance priority.

Second, you don't want the button to be bigger than it needs to be. A button that looked like this, [          Click Me          ], is obviously too big. You want the button to "hug" its contents without too much padding. This is the horizontal content hugging priority. For a button, it isn't as strong as the horizontal compression resistance priority.

Use the "contents" function:

$('#some-id').contents().find('html').html("some-html")

This is an old post but for anyone wanting to use variables as @centurian said the single quotes mean nothing will be expanded.

A simple way to get variables in is to do string concatenation since this is done by juxtaposition in bash the following should work:

sed -i -e "s/$var1/$var2/g" /tmp/file.txt

Maybe try this? It seems the problem is solved after remove all the handlers in my case.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

logging.basicConfig(filename='output.log', level=logging.INFO)
