The solution is isblank(cell)=false

following Donald's comment:

This variable applies when binary logging is enabled.

All I had to do was:

1. disabled log_bin in my.cnf (#log_bin)
2. restart mysql
3. import DB
4. enable log_bin
5. restart mysql

That step out that import problem.

(Then I'll review the programmer's code to suggest an improvement)

Use .blur().

The blur event is sent to an element when it loses focus. Originally, this event was only applicable to form elements, such as <input>. In recent browsers, the domain of the event has been extended to include all element types. An element can lose focus via keyboard commands, such as the Tab key, or by mouse clicks elsewhere on the page.

$("#myInputID").blur(); 

To change the color universally, this code should sit in the NavigationController's viewDidLoad function:

class NavigationController: UINavigationController, UIViewControllerTransitioningDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Status bar white font
        self.navigationBar.barStyle = UIBarStyle.Black
        self.navigationBar.tintColor = UIColor.whiteColor()
    }
}

To change it per ViewController you would have to reference the NavigationController from the ViewController and write similar lines in that ViewController's viewWillAppear function.

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

Following are the steps that will definitely work:

1. Open CMD : Press Windows+R from keyboard or just type "cmd" in windows search
2. Type Following in cmd : netstat -aon | find ":8080" | find "LISTENING"
3. See the last column : There will be some number like 2816 or similar.(It will differ from this)
4. Now open Task Manager (Keyboard shortcut : Ctrl+Shift+Esc)
5. In that, go to Details Tab and under PID Column, search for the number you found in step 3
6. Right Click on it and select end process
7. Now happily go to Netbeans and Run your program

NOTE : If you are running your program for the first time in Netbeans, it takes some time. So don't worry if it takes time.

With rlang 0.4.0 we have curly-curly operators ({{}}) which makes this very easy.

iris1 <- tbl_df(iris)

multipetal <- function(df, n) {
   varname <- paste("petal", n , sep=".")
   mutate(df, {{varname}} := Petal.Width * n)

We can also pass quoted/unquoted variable names to be assigned as column names.

multipetal <- function(df, name, n) {
   mutate(df, {{name}} := Petal.Width * n)
}

multipetal(iris1, temp, 3)

It works the same with

multipetal(iris1, "temp", 3)

It seems that the class is not compiled by Eclipse.

Few pointers could be-

1. Check if the .class file exists in your output folder.To know your output folder Right Click on Project->Properties->Java Build Path(Check at bottom).
2. Check if Project->build Automatically is checked in the menu.
3. Check if the HelloWorld class is in src folder or not.Right Click on Project->Properties->Java Build Path(Check source tab).

Rephrasing one of the answers in this post, instead of using cmd.split(). Try to use:

import shlex

args = shlex.split(cmd)

Then feed args to subprocess.Popen.

Check this doc for more info: https://docs.python.org/2/library/subprocess.html#popen-constructor

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

You can use howfat which also displays dependency statistics:

npx howfat -r tree jasmine

I had a same problem and I fix it with the following steps:

1. check the event log and if you see the errors like "cash version is not available for the offline mode" follow the steps.
2. click on View => Gradle then new window will open.
3. click on the WIFI icon and then sync the Gradle. "if you see different errors from what I mentioned in number one, please go to the file -> project structure -> and there is suggestion"

Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote:

git ls-remote --tags /url/to/upstream/repo

(as illustrated in "When listing git-ls-remote why there's “^{}” after the tag name?")

xbmono illustrates in the comments that quotes are needed:

git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"

Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):

git push --follow-tags

See Push git commits & tags simultaneously.

Regarding Atlassian SourceTree specifically:

Note that, from this thread, SourceTree ONLY shows local tags.

There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015 since Dec. 2015.

A simple workaround:

see a list of only unpushed tags?

git push --tags

or check the "Push all tags" box on the "Push" dialog box, all tags will be pushed to your remote.

That way, you will be "sure that they are present in remote so that other developers can pull them".

I'm sure there are other ways to accomplish this, but one solution would be to use join through the Query Builder.

If you have tables set up something like this:

users
    id
    ...

friends
    id
    user_id
    friend_id
    ...

votes, comments and status_updates (3 tables)
    id
    user_id
    ....

In your User model:

class User extends Eloquent {
    public function friends()
    {
        return $this->hasMany('Friend');
    }
}

In your Friend model:

class Friend extends Eloquent {
    public function user()
    {
        return $this->belongsTo('User');
    }
}

Then, to gather all the votes for the friends of the user with the id of 1, you could run this query:

$user = User::find(1);
$friends_votes = $user->friends()
    ->with('user') // bring along details of the friend
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id')
    ->get(['votes.*']); // exclude extra details from friends table

Run the same join for the comments and status_updates tables. If you would like votes, comments, and status_updates to be in one chronological list, you can merge the resulting three collections into one and then sort the merged collection.

Edit

To get votes, comments, and status updates in one query, you could build up each query and then union the results. Unfortunately, this doesn't seem to work if we use the Eloquent hasMany relationship (see comments for this question for a discussion of that problem) so we have to modify to queries to use where instead:

$friends_votes = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id');

$friends_comments = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('comments', 'comments.user_id', '=', 'friends.friend_id');

$friends_status_updates = 
    DB::table('status_updates')->where('status_updates.user_id','1')
    ->join('friends', 'status_updates.user_id', '=', 'friends.friend_id');

$friends_events = 
    $friends_votes
    ->union($friends_comments)
    ->union($friends_status_updates)
    ->get();

At this point, though, our query is getting a bit hairy, so a polymorphic relationship with and an extra table (like DefiniteIntegral suggests below) might be a better idea.

Okay, I'm not going to tell you a magical way of doing it because there isn't. If you have an action attribute set for a form element, it will redirect.

If you don't want it to redirect simply don't set any action and set onsubmit="someFunction();"

In your someFunction() you do whatever you want, (with AJAX or not) and in the ending, you add return false; to tell the browser not to submit the form...

You might consider using double slashes on your directory e.g

app.get('/',(req,res)=>{_x000D_
    res.sendFile('C:\\Users\\DOREEN\\Desktop\\Fitness Finder' + '/index.html')_x000D_
})

Do I give them a name and extension; if so what?

You may name your Dockerfiles however you like. The default filename is Dockerfile (without an extension), and using the default can make various tasks easier while working with containers.

Depending on your specific requirements you may wish to change the filename. If you're building for multiple architectures, for example, you may wish to add an extension indicating the architecture as the resin.io team has done for the HAProxy container their multi-container ARM example:

Dockerfile.aarch64
Dockerfile.amd64
Dockerfile.armhf
Dockerfile.armv7hf
Dockerfile.i386
Dockerfile.i386-nlp
Dockerfile.rpi

In the example provided, each Dockerfile builds from a different, architecture-specific, upstream image. The specific Dockerfile to use for the build may be specified using the --file, -f option when building your container using the command line.

After rollback check your tables , be sure of deletion.

If there is a problem delete tables manually from database application like phpmyadmin ( I'm using sequel pro for mac ).

Correct your down methods in the migration .

Note : Do rollback then migrate .. Don't use migrate:refresh to notice where is the error been .

After that you may test with new db for testing. to detect where is the problem.

Also try reading this question

I found git here

C:\Users\<User>\AppData\Local\GitHubDesktop\app-0.5.8\resources\app\git\cmd\git.exe

You have to write file name (git.exe) in the end of path otherwise it will give an error=5

Or you can check here also.

C:\Program Files\Git\bin\git.exe

In the activity:

mAdapter.updateAt(pos, text, completed);
mAdapter.removeAt(pos);

In the your adapter:

void removeAt(int position) {
    list.remove(position);
    notifyItemRemoved(position);
    notifyItemRangeChanged(position, list.size());
}

void updateAt(int position, String text, Boolean completed) {
    TodoEntity todoEntity = list.get(position);
    todoEntity.setText(text);
    todoEntity.setCompleted(completed);
    notifyItemChanged(position);
}

Create UITextField Extension like this:

extension UITextField{
   @IBInspectable var placeHolderColor: UIColor? {
        get {
            return self.placeHolderColor
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor: newValue!])
        }
    }
}

And in your storyboard or .xib. You will see

shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="#f6eef1" />

    <stroke
        android:width="2dp"
        android:color="#000000" />

    <padding
        android:bottom="5dp"
        android:left="5dp"
        android:right="5dp"
        android:top="5dp" />

    <corners android:radius="5dp" />

</shape>

and inside you layout

<LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginBottom="10dp"
        android:clipChildren="true"
        android:background="@drawable/shape">

        <ImageView
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:src="@drawable/your image"
             android:background="@drawable/shape">

</LinearLayout>

 override func viewWillAppear(animated: Bool)
 {
 super.viewWillAppear(animated)

 NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil)
 NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil)

 }

 // MARK: - keyboard
 func keyboardWillShow(notification: NSNotification) 
{

if let userInfo = notification.userInfo {
if let keyboardSize = (userInfo[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
let contentInsets = self.tblView.contentInset as UIEdgeInsets
self.tblView.contentInset = UIEdgeInsets(top: contentInsets.top, left: contentInsets.left, bottom: keyboardSize.height, right:contentInsets.right)
                    // ...
                } else {
                    // no UIKeyboardFrameBeginUserInfoKey entry in userInfo
                }
            } else {
                // no userInfo dictionary in notification
            }
        }

func keyboardWillHide(notification: NSNotification) 
{
let contentInsets = self.tblView.contentInset as UIEdgeInsets
self.tblView.contentInset = UIEdgeInsets(top: contentInsets.top, left: contentInsets.left, bottom: 0, right:contentInsets.right)
 }

In some cases no "No module ..." can appear even on local files. In such cases you just need to mark appropriate directories as "source directories":

Wrap your two+ function calls in another function/method. Here are a couple variants of that idea:

1) Separate method

var Test = React.createClass({
   onClick: function(event){
      func1();
      func2();
   },
   render: function(){
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
});

or with ES6 classes:

class Test extends React.Component {
   onClick(event) {
      func1();
      func2();
   }
   render() {
      return (
         <a href="#" onClick={this.onClick}>Test Link</a>
      );
   }
}

2) Inline

<a href="#" onClick={function(event){ func1(); func2()}}>Test Link</a>

or ES6 equivalent:

<a href="#" onClick={() => { func1(); func2();}}>Test Link</a>

                {

                }
            }
        }
        private void OnGUI()
        {
            if (this.MainMenu)
            {
                this.RT_MainMenu = GUILayout.Window(this.ID_RTMainMenu, this.RT_MainMenu, new GUI.WindowFunction(this.Menu_MainMenu), "MainMenu", new GUILayoutOption[0]);
            }
        }

}

make sure you use the POST to insert the data. Actually you were using GET.

The best way of sending an error response would be return res.status(400).send({ message: 'An error has occurred' }).

Then, in your frontend you can catch it using something like this:

        url: your_url,
        method: 'POST',
        headers: headers,
        data: JSON.stringify(body),
    })
        .then((res) => {
            console.log('success', res);
        })
        .catch((err) => {
            err.response && err.response.data && this.setState({ apiResponse: err.response.data })
        })

Just logging err won't work, as your sent message object resides in err.response.data.

Hope that helps!

in Swift 3.0 or Later

passwordTextField.isSecureTextEntry = true

An easy way to do this is using the pandas library like this.

import pandas as pd
fields = ['star_name', 'ra']

df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print df.keys()
# See content in 'star_name'
print df.star_name

The problem here was the skipinitialspace which remove the spaces in the header. So ' star_name' becomes 'star_name'

What I have found is that simply wrapping code in the componentDidMount or componentDidUpdate with a setTimeout with a time of 0 milliseconds ensures that the browser DOM has been updated with the React changes before executing the setTimeout function.

Like this:

componentDidMount() {
    setTimeout(() => {
        $("myclass") //  $ is available here
    }, 0)
}

This puts the anonymous function on the JS Event Queue to run immediately after the currently running React stack frame has completed.

var Hello = React.createClass({
    render: function() {
      return (
        <div className="divClass">
           <img src={this.props.url} alt={`${this.props.title}'s picture`}  className="img-responsive" />
           <span>Hello {this.props.name}</span>
        </div>
      );
    }
});

This works for me, 12.04, python2.7.6

sudo apt-get install libxml2 libxml2-dev libxslt1-dev
sudo apt-get install lxml

Here is a simplified version of the 2-step approach using build and commit, without shell scripts. It involves:

1. Building the image partially, without volumes
2. Running a container with volumes, making changes, then committing the result, replacing the original image name.

With relatively minor changes the additional step adds only a few seconds to the build time.

Basically:

docker build -t image-name . # your normal docker build

# Now run a command in a throwaway container that uses volumes and makes changes:
docker run -v /some:/volume --name temp-container image-name /some/post-configure/command

# Replace the original image with the result:
# (reverting CMD to whatever it was, otherwise it will be set to /some/post-configure/command)   
docker commit --change="CMD bash" temp-container image-name 

# Delete the temporary container:
docker rm temp-container

In my use case I want to pre-generate a maven toolchains.xml file, but my many JDK installations are on a volume that isn't available until runtime. Some of my images are not compatible with all the JDKS, so I need to test compatibility at build time and populate toolchains.xml conditionally. Note that I don't need the image to be portable, I'm not publishing it to Docker Hub.

This code will verify the json independently of param object order.

var isEqualsJson = (obj1,obj2)=>{
    keys1 = Object.keys(obj1);
    keys2 = Object.keys(obj2);

    //return true when the two json has same length and all the properties has same value key by key
    return keys1.length === keys2.length && Object.keys(obj1).every(key=>obj1[key]==obj2[key]);
}

var obj1 = {a:1,b:2,c:3};
var obj2 = {a:1,b:2,c:3}; 

console.log("json is equals: "+ isEqualsJson(obj1,obj2));
alert("json is equals: "+ isEqualsJson(obj1,obj2));

I managed to load an application.properties file in external path while using -jar option.

The key was PropertiesLauncher.

To use PropertiesLauncher, pom.xml file must be changed like this:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>  <!-- added -->
                <layout>ZIP</layout> <!-- to use PropertiesLaunchar -->

For this, I referenced the following StackOverflow question: spring boot properties launcher unable to use . BTW, In Spring Boot Maven Plugin document(http://docs.spring.io/spring-boot/docs/1.1.7.RELEASE/maven-plugin/repackage-mojo.html), there is no mention that specifying ZIP triggers that PropertiesLauncher is used. (Perhaps in another document?)

After the jar file had been built, I could see that the PropertiesLauncher is used by inspecting Main-Class property in META-INF/MENIFEST.MF in the jar.

Now, I can run the jar as follows(in Windows):

java -Dloader.path=file:///C:/My/External/Dir,MyApp-0.0.1-SNAPSHOT.jar -jar MyApp-0.0.1-SNAPSHOT.jar

Note that the application jar file is included in loader.path.

Now an application.properties file in C:\My\External\Dir\config is loaded.

As a bonus, any file (for example, static html file) in that directory can also be accessed by the jar since it's in the loader path.

As for the non-jar (expanded) version mentioned in UPDATE 2, maybe there was a classpath order problem.

I had the same question, and have spent all day trying out different packages.

I had originally used matlibplot: and was not happy with either mapping categories to predefined colors; or grouping/aggregating then iterating through the groups (and still having to map colors). I just felt it was poor package implementation.

Seaborn wouldn't work on my case, and Altair ONLY works inside of a Jupyter Notebook.

The best solution for me was PlotNine, which "is an implementation of a grammar of graphics in Python, and based on ggplot2".

Below is the plotnine code to replicate your R example in Python:

from plotnine import *
from plotnine.data import diamonds

g = ggplot(diamonds, aes(x='carat', y='price', color='color')) + geom_point(stat='summary')
print(g)

So clean and simple :)

I had the same problem, and it was caused by line for insecured registry in: /etc/default/docker

Check these steps.

1. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check TCP/IP is enabled.
2. Open SSMS in run, and check you are able to login to server using specfied username/password and/or using windows authentication.
3. repeat step 1 for SQL native client config also

You cannot auto increment the char values. It should be int or long(integers or floating points). Try with this,

CREATE TABLE discussion_topics (
    topic_id int(5) NOT NULL AUTO_INCREMENT,
    project_id char(36) NOT NULL,
    topic_subject VARCHAR(255) NOT NULL,
    topic_content TEXT default NULL,
    date_created DATETIME NOT NULL,
    date_last_post DATETIME NOT NULL,
    created_by_user_id char(36) NOT NULL,
    last_post_user_id char(36) NOT NULL,
    posts_count char(36) default NULL,
    PRIMARY KEY (`topic_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

Hope this helps

If you are doing machine learning and use tensorflow, many float are of 'float32', not 'float64', and none of the methods mentioned in this thread likely to work. You will have to first convert to float64 first.

x.astype('float')

before round(...).

 ymin, ymax = axes.get_ylim()

If you are using the plt api directly, you can avoid calls to axes altogether:

def myplotfunction(title, values, errors, plot_file_name):

    # plot errorbars
    indices = range(0, len(values))
    fig = plt.figure()
    plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')

    plt.ylim([-0.5, len(values) - 0.5])
    plt.xlabel('My x-axis title')
    plt.ylabel('My y-axis title')

    # title
    plt.title(title)

    # save as file
    plt.savefig(plot_file_name)

   # close figure
    plt.close(fig)

First at all i'm seing your code and you haven't any controller. So i suggest that you use a controller. I think you have to use a controller because your variable {{myStyle}} isn't compile because the 2 curly brace are visible and they shouldn't.

Second you have to use ng-model for your input, this directive will bind the value of the input to your variable.

This was build with Xcode 10.1 and Swift 4

Perfect combination "Alamofire"(4.8.1) and "SwiftyJSON"(4.2.0). First you should install both pods

pod 'Alamofire' and pod 'SwiftyJSON'

The server response in JSON format:

{
  "args": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip;q=1.0, compress;q=0.5", 
    "Accept-Language": "en;q=1.0", 
    "Host": "httpbin.org", 
    "User-Agent": "AlamoFire TEST/1.0 (com.ighost.AlamoFire-TEST; build:1; iOS 12.1.0) Alamofire/4.8.1"
  }, 
  "origin": "200.55.140.181, 200.55.140.181", 
  "url": "https://httpbin.org/get"
}

In this case I want print the "Host" info : "Host": "httpbin.org"

Alamofire.request("https://httpbin.org/get").validate().responseJSON { response in
        switch response.result {
        case .success:
            print("Validation Successful)")

            if let json = response.data {
                do{
                    let data = try JSON(data: json)
                    let str = data["headers"]["Host"]
                    print("DATA PARSED: \(str)")
                }
                catch{
                print("JSON Error")
                }

            }
        case .failure(let error):
            print(error)
        }
    }

Keep Calm and happy Code

Use the package plyr with lapply to get frequencies for every value (level) and every variable (factor) in your data frame.

library(plyr)
lapply(df, count)

Columns("A:E").Select

Can be directly replaced by

Columns(1).Resize(, 5).EntireColumn.Select

Where 1 can be replaced by a variable

n = 5
Columns(n).Resize(, n+4).EntireColumn.Select

In my opinion you are best dealing with a block of columns rather than looping through columns n to n + 4 as it is more efficient.

In addition, using select will slow your code down. So instead of selecting your columns and then performing an action on the selection try instead to perform the action directly. Below is an example to change the colour of columns A-E to yellow.

Columns(1).Resize(, 5).EntireColumn.Interior.Color = 65535

Also, if you set your build target device, the problem will go away when you testing and debugging. The code signed is only need when you trying to deploy your app to an actually physical device

I changed mine from "myIphone" to simulator iPhone 6 Plus, and it solves the problem while I'm developing the app.

Add all event listeners when a window loads.Works like a charm no matter where you put script tags.

window.addEventListener("load", startup);

function startup() {

  document.getElementById("el").addEventListener("click", myFunc);
  document.getElementById("el2").addEventListener("input", myFunc);

}

myFunc(){}

Alternate solution

Create a column that will store the month:

data['month'] = data['date'].dt.month

Create a column that will store the year:

data['year'] = data['date'].dt.year

You can use the spring-boot-starter dependency. This will not have the web stuff.

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

One line answer would be

myseries.to_frame(name='my_column_name')

Or

myseries.reset_index(drop=True, inplace=True)  # As needed

You can easily make your own 'AlertView' and use it everywhere.

alertView("You really want this?");

Implement it once:

private void alertView( String message ) {
 AlertDialog.Builder dialog = new AlertDialog.Builder(context);
 dialog.setTitle( "Hello" )
       .setIcon(R.drawable.ic_launcher)
       .setMessage(message)
//     .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
//      public void onClick(DialogInterface dialoginterface, int i) {
//          dialoginterface.cancel();   
//          }})
      .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialoginterface, int i) {   
        }               
        }).show();
 }

Add the annotation @Repository to the implementation of UserDaoImpl

@Repository
public class UserDaoImpl implements UserDao {
    private static Log log = LogFactory.getLog(UserDaoImpl.class);

    @Autowired
    @Qualifier("sessionFactory")
    private LocalSessionFactoryBean sessionFactory;

    //...

}

• Run this inside your project root directory i am using in laravel root directory.

vendor/bin/phpunit --filter 'Your method name'

Example with custom method name.

 /** @test //Initilize this for custom method name, without test keyword

  public function only_logged_in_user_see_dashboard()
  {
    $response = $this->get('/dashboard')
                   ->assertRedirect('/login');

*/
 public function testBasicTest()
 {
  $this->assertTrue(true);
 }

this error occurs when required memory allocated for execution is less than memory required for running process. By default, Node memory size is 512 mb to increase this you need to type the following command :

node --max-old-space-size= <NewSize> <fileName>

If you're encountering this in Jupyter/Jupyerlab while trying to pip install foo, you can sometimes work around it by using !python -m pip install foo instead.

As sjdh also mentioned, ggplot2 comes to the rescue. A more intuitive way without making a dummy data set is to use xlim:

library(ggplot2)
eq <- function(x){sin(x)}
base <- ggplot() + xlim(0, 30)
base + geom_function(fun=eq)

Additionally, for a smoother graph we can set the number of points over which the graph is interpolated using n:

base + geom_function(fun=eq, n=10000)

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

In my case it was python path issue.

#1 First set your PYTHONPATH

#2 then set DJANGO_SETTINGS_MODULE

(venv) shakeel@workstation:~/project_path$ export PYTHONPATH=/home/shakeel/project_path
(venv) shakeel@workstation:~/project_path$ export DJANGO_SETTINGS_MODULE=my_project.settings
(venv) shakeel@workstation:~/project_path$ django-admin dbshell
SQLite version 3.22.0 2018-01-22 18:45:57
Enter ".help" for usage hints.

otherwise python manage.py shell works like charm.

The solution to this was just to change the USB cable, having enabled ADB Integration via

One option is to declare a default value for 'new_field':

new_field = models.CharField(max_length=140, default='DEFAULT VALUE')

another option is to declare 'new_field' as a nullable field:

new_field = models.CharField(max_length=140, null=True)

If you decide to accept 'new_field' as a nullable field you may want to accept 'no input' as valid input for 'new_field'. Then you have to add the blank=True statement as well:

new_field = models.CharField(max_length=140, blank=True, null=True)

Even with null=True and/or blank=True you can add a default value if necessary:

new_field = models.CharField(max_length=140, default='DEFAULT VALUE', blank=True, null=True)

use desc tablename from Hive CLI or beeline to get all the column names. If you want the column names in a file then run the below command from the shell.

$ hive -e 'desc dbname.tablename;' > ~/columnnames.txt

where dbname is the name of the Hive database where your table is residing You can find the file columnnames.txt in your root directory.

Try this elegant UIView extension for constraints. You can do constraints easy as:

 - firstView.coverWholeSuperview()
 - firstView.constraints(size: CGSize(width: 44, height: 44), centerX: view.centerXAnchor, centerY: view.centerXAnchor)
 - firstView.constraints(top: view.topAnchor, 
                         leading: secondView.leadingAnchor, 
                         bottom: view.bottomAnchor, 
                         trailing: secondView.trailingAnchor, 
                         padding: UIEdgeInsets(top: 12, left: 12, bottom: 12, right: 12))

Here is extension, just copy it to your project.

I had the same problem. I'm no expert but this is the solution we used: Before you filter your data, first create a temporary column to populate your entire data set with your original sort order. Auto number the temporary "original sort order" column. Now filter your data. Copy and paste the filtered data into a new worksheet. This will move only the filtered data to the new sheet so that your row numbers will become consecutive. Now auto number your desired field. Go back to your original worksheet and delete the filtered rows. Copy and paste the newly numbered data from the secondary sheet onto the bottom of your original worksheet. Then clear your filter and sort the worksheet by the temporary "original sort order" column. This will put your newly numbered data back into its original order and you can then delete the temporary column.

Kotlin & clean, so you don't have to refactor before code review:

private fun addQueryParameters(url: String?): String? {
        val uri = URI(url)

        val queryParams = StringBuilder(uri.query.orEmpty())
        if (queryParams.isNotEmpty())
            queryParams.append('&')

        queryParams.append(URLEncoder.encode("$QUERY_PARAM=$param", Xml.Encoding.UTF_8.name))
        return URI(uri.scheme, uri.authority, uri.path, queryParams.toString(), uri.fragment).toString()
    }

You can use any parent methods. For this you should to send this methods from you parent to you child like any simple value. And you can use many methods from the parent at one time. For example:

var Parent = React.createClass({
    someMethod: function(value) {
        console.log("value from child", value)
    },
    someMethod2: function(value) {
        console.log("second method used", value)
    },
    render: function() {
      return (<Child someMethod={this.someMethod} someMethod2={this.someMethod2} />);
    }
});

And use it into the Child like this (for any actions or into any child methods):

var Child = React.createClass({
    getInitialState: function() {
      return {
        value: 'bar'
      }
    },
    render: function() {
      return (<input type="text" value={this.state.value} onClick={this.props.someMethod} onChange={this.props.someMethod2} />);
    }
});

Object to array

$array = (array) $players_Obj;  

$object = new StdClass;
$object->foo = 1;
$object->bar = 2;

var_dump( (array) $object );

Output:

array(2) {
    'foo' => int(1)
    'bar' => int(2)
}

The problem is that dataTable is not defined at the point you are calling this method.

Ensure that you are loading the .js files in the correct order:

<script src="/Scripts/jquery.dataTables.js"></script>
<script src="/Scripts/dataTables.bootstrap.js"></script>

You've almost done it. However setting flex: 0 0 <basis> declaration to the columns would prevent them from growing/shrinking; And the <basis> parameter would define the width of columns.

In addition, you could use CSS3 calc() expression to specify the height of columns with the respect to the height of the header.

#productShowcaseTitle {
  flex: 0 0 100%; /* Let it fill the entire space horizontally */
  height: 100px;
}

#productShowcaseDetail,
#productShowcaseThumbnailContainer {
  height: calc(100% - 100px); /* excluding the height of the header */
}

#productShowcaseContainer {_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
_x000D_
  height: 600px;_x000D_
  width: 580px;_x000D_
}_x000D_

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div> element, it would be achieved without using calc() as follows:

<div class="contentContainer"> <!-- Added wrapper -->
    <div id="productShowcaseDetail"></div>
    <div id="productShowcaseThumbnailContainer"></div>
</div>

#productShowcaseContainer {
  display: flex;

It looks like you are trying to use (almost) straight up C code here. Go has a few differences.

• First off, you can't initialize arrays and slices as const. The term const has a different meaning in Go, as it does in C. The list should be defined as var instead.
• Secondly, as a style rule, Go prefers basenameOpts as opposed to basename_opts.
• There is no char type in Go. You probably want byte (or rune if you intend to allow unicode codepoints).
• The declaration of the list must have the assignment operator in this case. E.g.: var x = foo.
• Go's parser requires that each element in a list declaration ends with a comma. This includes the last element. The reason for this is because Go automatically inserts semi-colons where needed. And this requires somewhat stricter syntax in order to work.

For example:

type opt struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}

var basenameOpts = []opt { 
    opt {
        shortnm: 'a', 
        longnm: "multiple", 
        needArg: false, 
        help: "Usage for a",
    },
    opt {
        shortnm: 'b', 
        longnm: "b-option", 
        needArg: false, 
        help: "Usage for b",
    },
}

An alternative is to declare the list with its type and then use an init function to fill it up. This is mostly useful if you intend to use values returned by functions in the data structure. init functions are run when the program is being initialized and are guaranteed to finish before main is executed. You can have multiple init functions in a package, or even in the same source file.

    type opt struct {
        shortnm      byte
        longnm, help string
        needArg      bool
    }

    var basenameOpts []opt

    func init() { 
        basenameOpts = []opt{
            opt {
                shortnm: 'a', 
                longnm: "multiple", 
                needArg: false, 
                help: "Usage for a",
            },
            opt {
                shortnm: 'b', 
                longnm: "b-option", 
                needArg: false, 
               help: "Usage for b",
            },
        }
    }

Since you are new to Go, I strongly recommend reading through the language specification. It is pretty short and very clearly written. It will clear a lot of these little idiosyncrasies up for you.

Try this:

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let indexPath = tableView.indexPathForSelectedRow() //optional, to get from any UIButton for example

    let currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell

    print(currentCell.textLabel!.text)

If I understood well, you want to remove a specific character only if it is at the beginning or at the end of the string (ex: ||fo||oo|||| should become foo||oo). You can create an ad hoc function as follows:

function trimChar(string, charToRemove) {
    while(string.charAt(0)==charToRemove) {
        string = string.substring(1);
    }

    while(string.charAt(string.length-1)==charToRemove) {
        string = string.substring(0,string.length-1);
    }

    return string;
}

I tested this function with the code below:

var str = "|f|oo||";
$( "#original" ).html( "Original String: '" + str + "'" );
$( "#trimmed" ).html( "Trimmed: '" + trimChar(str, "|") + "'" );

You can usee the following code: week_start = str(datetime.today() - timedelta(days=datetime.today().weekday() % 7)).split(' ')[0]

# docker exec -d container_id command 

Ex:

# docker exec -d xcdefrdtt service jira stop 

Try this tag on the pages that use the ActiveX control:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE10">

Note: this has to be the very first element in the <head> section.

Since you are always initialising self.listMyData to an empty list in clkFindMost your code will always lead to this error* because after that both unique_names and frequencies are empty iterables, so fix this.

Another thing is that since you're iterating over a set in that method then calculating frequency makes no sense as set contain only unique items, so frequency of each item is always going to be 1.

Lastly dict.get is a method not a list or dictionary so you can't use [] with it:

Correct way is:

if frequencies.get(name):

And Pythonic way is:

if name in frequencies:

The Pythonic way to get the frequency of items is to use collections.Counter:

from collections import Counter   #Add this at the top of file.

def clkFindMost(self, parent):

        #self.listMyData = []   
        if self.listMyData:
           frequencies = Counter(self.listMyData)
           self.txtResults.Value = max(frequencies, key=frequencies.get)
        else:
           self.txtResults.Value = '' 

max() and min() throw such error when an empty iterable is passed to them. You can check the length of v before calling max() on it.

>>> lst = []
>>> max(lst)

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    max(lst)
ValueError: max() arg is an empty sequence
>>> if lst:
    mx = max(lst)
else:
    #Handle this here

If you are using it with an iterator then you need to consume the iterator first before calling max() on it because boolean value of iterator is always True, so we can't use if on them directly:

>>> it = iter([])
>>> bool(it)
True
>>> lst = list(it)
>>> if lst:
       mx = max(lst)
    else:
      #Handle this here   

Good news is starting from Python 3.4 you will be able to specify an optional return value for min() and max() in case of empty iterable.

How about creating a function to hijack the reject and return it ?

function createRejectablePromise(handler) {
  let _reject;

  const promise = new Promise((resolve, reject) => {
    _reject = reject;

    handler(resolve, reject);
  })

  promise.reject = _reject;
  return promise;
}

// Usage
const { reject } = createRejectablePromise((resolve) => {
  setTimeout(() => {
    console.log('resolved')
    resolve();
  }, 2000)

});

reject();

At first you need to have enabled curl extension in PHP. Then you can use this function:

function file_get_contents_ssl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_REFERER, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3000); // 3 sec.
    curl_setopt($ch, CURLOPT_TIMEOUT, 10000); // 10 sec.
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

It works similar to function file_get_contents(..).

Example:

echo file_get_contents_ssl("https://www.example.com/");

Output:

<!doctype html>
<html>
<head>
    <title>Example Domain</title>
...

Though this isn't a DIRECT answer to your question, I just encountered a similar problem, and thought I'd mentioned it:

I had an instance where it was instantiating a new (no doubt very inefficent) record for data.frame (a result of recursive searching) and it was giving me the same error.

I had this:

return(
  data.frame(
    user_id = gift$email,
    sourced_from_agent_id = gift$source,
    method_used = method,
    given_to = gift$account,
    recurring_subscription_id = NULL,
    notes = notes,
    stringsAsFactors = FALSE
  )
)

turns out... it was the = NULL. When I switched to = NA, it worked fine. Just in case anyone else with a similar problem hits THIS post as I did.

In [21]: df = pd.DataFrame([(1,2,3), ('foo','bar','baz'), (4,5,6)])

In [22]: df
Out[22]: 
     0    1    2
0    1    2    3
1  foo  bar  baz
2    4    5    6

Set the column labels to equal the values in the 2nd row (index location 1):

In [23]: df.columns = df.iloc[1]

If the index has unique labels, you can drop the 2nd row using:

In [24]: df.drop(df.index[1])
Out[24]: 
1 foo bar baz
0   1   2   3
2   4   5   6

If the index is not unique, you could use:

In [133]: df.iloc[pd.RangeIndex(len(df)).drop(1)]
Out[133]: 
1 foo bar baz
0   1   2   3
2   4   5   6

Using df.drop(df.index[1]) removes all rows with the same label as the second row. Because non-unique indexes can lead to stumbling blocks (or potential bugs) like this, it's often better to take care that the index is unique (even though Pandas does not require it).

You can use annotate your method with @Scheduled(cron ="0 1 1 * * ?").

0 - is for seconds

1- 1 minute

1 - hour of the day.

You need to put SongsTableSeeder into file SongsTableSeeder.php in the same directory where you have your DatabaseSeeder.php file.

And you need to run in your console:

tl;dr

Instant.now()

java.time

The troublesome old date-time classes bundled with the earliest versions of Java have been supplanted by the java.time classes built into Java 8 and later. See Oracle Tutorial. Much of the functionality has been back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

Instant

An Instant represents a moment on the timeline in UTC with a resolution of up to nanoseconds.

Instant instant = Instant.now();

The toString method generates a String object with text representing the date-time value using one of the standard ISO 8601 formats.

String output = instant.toString();  

2016-06-27T19:15:25.864Z

The Instant class is a basic building-block class in java.time. This should be your go-to class when handling date-time as generally the best practice is to track, store, and exchange date-time values in UTC.

OffsetDateTime

But Instant has limitations such as no formatting options for generating strings in alternate formats. For more flexibility, convert from Instant to OffsetDateTime. Specify an offset-from-UTC. In java.time that means a ZoneOffset object. Here we want to stick with UTC (+00) so we can use the convenient constant ZoneOffset.UTC.

OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC );

2016-06-27T19:15:25.864Z

Or skip the Instant class.

OffsetDateTime.now( ZoneOffset.UTC )

Now with an OffsetDateTime object in hand, you can use DateTimeFormatter to create String objects with text in alternate formats. Search Stack Overflow for many examples of using DateTimeFormatter.

ZonedDateTime

When you want to display wall-clock time for some particular time zone, apply a ZoneId to get a ZonedDateTime.

In this example we apply Montréal time zone. In the summer, under Daylight Saving Time (DST) nonsense, the zone has an offset of -04:00. So note how the time-of-day is four hours earlier in the output, 15 instead of 19 hours. Instant and the ZonedDateTime both represent the very same simultaneous moment, just viewed through two different lenses.

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

2016-06-27T15:15:25.864-04:00[America/Montreal]

Converting

While you should avoid the old date-time classes, if you must you can convert using new methods added to the old classes. Here we use java.util.Date.from( Instant ) and java.util.Date::toInstant.

java.util.Date utilDate = java.util.Date.from( instant );

And going the other direction.

Instant instant= utilDate.toInstant();

Similarly, look for new methods added to GregorianCalendar (subclass of Calendar) to convert to and from java.time.ZonedDateTime.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Do what Spectravideo328 answered and:

Try to UNCHECK the iOS 7 and later box and CHECK the iOS 6 and prior box in the asset catalog. There seems to be a bug with the iOS 7 Launch Image. (These both have the same Launch Images except for the 320x480 one)

Hope this helps, it did help for me!

In the general case, the answer is No.

However, you can set the debugger to break at the point where the exception is first thrown. At that time, the key which was not present will be accessible as a value in the call stack.

In Visual Studio, this option is located here:

Debug → Exceptions... → Common Language Runtime Exceptions → System.Collections.Generic

There, you can check the Thrown box.

For more specific instances where information is needed at runtime, provided your code uses IDictionary<TKey, TValue> and not tied directly to Dictionary<TKey, TValue>, you can implement your own dictionary class which provides this behavior.

I encounter similar problem when installing oracle 11gR2 on Windows 2012 server. the problem is solved when I run cmd.exe as Admistrator privilege and run "lsnrctl start LISTENER".

You can also try below:

Map.Entry<String, Integer> entry = myMap.firstEntry();
System.out.println("First Value = " + entry);

When you use the start command to a website it will use the default browser by default but if you want to use a specific browser then use start iexplorer.exe www.website.com

Also you cannot have http:// in the url.

Debugging build step failures is indeed very annoying.

The best solution I have found is to make sure that each step that does real work succeeds, and adding a check after those that fails. That way you get a committed layer that contains the outputs of the failed step that you can inspect.

I don't know if you are still having this problem, but I had the same problem and had a different fix than what was listed in the other answer. I did install XAMPP under C:\xampp\, and my user is an admin, but there was also something else.

I had to manually go give my user full access to the C:\Users\XAMPP\ directory. By default (at least on my machine) Windows did not give my admin user rights to this new user's directory, but this is where XAMPP stores all of it's config files. Once I gave myself full access to this, everything worked perfectly.

Hope this helps!

UPDATE!

In retrospect, I think that I must have accidentally typed in "C:\Users\XAMPP\" as the install folder during the installation process. So I think the most important thing is to make sure that the user you are actually signed into Windows as when you start XAMPP has full access to the folder that it was actually installed to.

There are only two ways to put a value into an array, and one is just syntactic sugar for the other:

a[i] = v;
*(a+i) = v;

Thus, to put something as the 4th element, you don't have any choice but arr[4] = 5. However, it should fail in your code, because the array is only allocated for 4 elements.

You've to create empty constructor because JAX-RS initializes the classes... Your constructor must have no arguments:

@XmlRootElement
public class Student implements Serializable {

    public String first_name;
    public String last_name;

    public String getFirst_name() {
        return first_name;
    }

    public void setFirst_name(String first_name) {
        this.first_name = first_name;
    }

    public String getLast_name() {
        return last_name;
    }

    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }

    public Student()
    {
        first_name = "Fahad";
        last_name = "Mullaji";
    }


 public Student()
    {
    }
}

I had this error too because in the file where I used @Transactional annotation, I was importing the wrong class

import javax.transaction.Transactional; 

Instead of javax, use

import org.springframework.transaction.annotation.Transactional;
