You could set the width of the abbrev column to a fixed pixel width, then set the width of the description column to the width of the DataGridView, minus the sum of the widths of the other columns and some extra margin (if you want to prevent a horizontal scrollbar from appearing on the DataGridView):

dataGridView1.Columns[1].Width = 108;  // or whatever width works well for abbrev
dataGridView1.Columns[2].Width = 
    dataGridView1.Width 
    - dataGridView1.Columns[0].Width 
    - dataGridView1.Columns[1].Width 
    - 72;  // this is an extra "margin" number of pixels

If you wanted the description column to always take up the "remainder" of the width of the DataGridView, you could put something like the above code in a Resize event handler of the DataGridView.

An enumerated type is basically a data type that lets you describe each member of a type in a more readable and reliable way.

Here is a simple example to explain why:

Assuming you are writing a method that has something to do with seasons:

The int enum pattern

First, you declared some int static constants to represent each season.

public static final int SPRING = 0;
public static final int SUMMER = 1;
public static final int FALL = 2;
public static final int WINTER = 2;

Then, you declared a method to print name of the season into the console.

public void printSeason(int seasonCode) {
    String name = "";
    if (seasonCode == SPRING) {
        name = "Spring";
    }
    else if (seasonCode == SUMMER) {
        name = "Summer";
    }
    else if (seasonCode == FALL) {
        name = "Fall";
    }
    else if (seasonCode == WINTER) {
        name = "Winter";
    }
    System.out.println("It is " + name + " now!");
}

So, after that, you can print a season name like this.

printSeason(SPRING);
printSeason(WINTER);

This is a pretty common (but bad) way to do different things for different types of members in a class. However, since these code involves integers, so you can also call the method like this without any problems.

printSeason(0);
printSeason(1);

or even like this

printSeason(x - y);
printSeason(10000);

The compiler will not complain because these method calls are valid, and your printSeason method can still work.

But something is not right here. What does a season code of 10000 supposed to mean? What if x - y results in a negative number? When your method receives an input that has no meaning and is not supposed to be there, your program knows nothing about it.

You can fix this problem, for example, by adding an additional check.

...
else if (seasonCode == WINTER) {
    name = "Winter";
}
else {
    throw new IllegalArgumentException();
}
System.out.println(name);

Now the program will throw a RunTimeException when the season code is invalid. However, you still need to decide how you are going to handle the exception.

By the way, I am sure you noticed the code of FALL and WINTER are both 2, right?

You should get the idea now. This pattern is brittle. It makes you write condition checks everywhere. If you're making a game, and you want to add an extra season into your imaginary world, this pattern will make you go though all the methods that do things by season, and in most case you will forget some of them.

You might think class inheritance is a good idea for this case. But we just need some of them and no more.

That's when enum comes into play.

Use enum type

In Java, enum types are classes that export one instance for each enumeration constant via a public static final field.

Here you can declare four enumeration constants: SPRING, SUMMER, FALL, WINTER. Each has its own name.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter");

    private String name;

    Season(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Now, back to the method.

public void printSeason(Season season) {
    System.out.println("It is " + season.getName() + " now!");
}

Instead of using int, you can now use Season as input. Instead of a condition check, you can tell Season to give you its name.

This is how you use this method now:

printSeason(Season.SPRING);
printSeason(Season.WINTER);
printSeason(Season.WHATEVER); <-- compile error

You will get a compile-time error when you use an incorrect input, and you're guaranteed to get a non-null singleton reference of Season as long as the program compiles.

When we need an additional season, we simply add another constant in Season and no more.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter"), 
    MYSEASON("My Season");

...

Whenever you need a fixed set of constants, enum can be a good choice (but not always). It's a more readable, more reliable and more powerful solution.

Freddy's answer helped me a lot to get this working. For the sake of completeness here's how you could implement hashing of the token:

private string ComputeHash(Guid input)
{
    byte[] source = input.ToByteArray();

    var encoder = new SHA256Managed();
    byte[] encoded = encoder.ComputeHash(source);

    return Convert.ToBase64String(encoded);
}

In CreateAsync:

var guid = Guid.NewGuid();
...
_refreshTokens.TryAdd(ComputeHash(guid), refreshTokenTicket);
context.SetToken(guid.ToString());

ReceiveAsync:

public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
{
    Guid token;

    if (Guid.TryParse(context.Token, out token))
    {
        AuthenticationTicket ticket;

        if (_refreshTokens.TryRemove(ComputeHash(token), out ticket))
        {
            context.SetTicket(ticket);
        }
    }
}

kindly use:

$('#myIframe').on('load', function(){
    //your code (will be called once iframe is done loading)
});

Updated my answer as the standards changed.

git branch --set-upstream master origin/master

This will add the following info to your config file:

[branch "master"]
    remote = origin
    merge = refs/heads/master

If you have branch.autosetuprebase = always then it will also add:

    rebase = true

In additions, now it is possible to do with class and static

'use strict'

class Foo {
 static talk() {
     console.log('talk')
 };

 speak() {
     console.log('speak')
 };

};

will give

var a = new Foo();
Foo.talk();  // 'talk'
a.talk();    // err 'is not a function'
a.speak();   // 'speak'
Foo.speak(); // err 'is not a function'

Try to connect to the repository using command line SVN to see if you get a similar error.

$ svn checkout http://svn.python.org/projects/peps/trunk

If you keep getting the error, it is probably an issue with your proxy server. I have found that I can't check out internet based SVN projects at work because the firewall blocks most HTTP commands. It only allows GET, POST and others necessary for browsing.

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

The python interpreter compiles the *.py script file and saves the results of the compilation to the __pycache__ directory.

When the project is executed again, if the interpreter identifies that the *.py script has not been modified, it skips the compile step and runs the previously generated *.pyc file stored in the __pycache__ folder.

When the project is complex, you can make the preparation time before the project is run shorter. If the program is too small, you can ignore that by using python -B abc.py with the B option.

Mozilla Developer Network has a nice description and example of onbeforeunload.

If you want to warn the user before leaving the page if your page is dirty (i.e. if user has entered some data):

window.addEventListener('beforeunload', function(e) {
  var myPageIsDirty = ...; //you implement this logic...
  if(myPageIsDirty) {
    //following two lines will cause the browser to ask the user if they
    //want to leave. The text of this dialog is controlled by the browser.
    e.preventDefault(); //per the standard
    e.returnValue = ''; //required for Chrome
  }
  //else: user is allowed to leave without a warning dialog
});

CSS rules are inherited by default - hence the "cascading" name. To get what you want you need to use !important:

form div
{
    font-size: 12px;
    font-weight: bold;
}

div.content
{
    // any rule you want here, followed by !important
}

You simply need to enable it in the config.php and you can use $this->input->get('param_name'); to get parameters.

PyTypeObject PyDict_Type=

PyTypeObject PyDict_Type=
{
  PyObject_HEAD_INIT(&PyType_Type),
                     "dict",
                     dict_print,

watch the name field, in gcc it compile without warning, but in g++ it will, i don't know why.

in gcc (Compiling C), -Wno-write-strings is active by default.

in g++ (Compiling C++) -Wwrite-strings is active by default

This is why there is a different behaviour. For us using macros of Boost_python generates such warnings. So we use -Wno-write-strings when compiling C++ since we always use -Werror

Here is the syntax using jQuery $.get

$.get(url, data, successCallback, datatype)

So in your case, that would equate to,

var url = 'ajax.asp';
var data = { ajaxid: 4, UserID: UserID, EmailAddress: EmailAddress };
var datatype = 'jsonp';

function success(response) {
// do something here 
}

$.get('ajax.aspx', data, success, datatype)

Note $.get does not give you the opportunity to set an error handler. But there are several ways to do it either using $.ajaxSetup(), $.ajaxError() or chaining a .fail on your $.get like below

$.get(url, data, success, datatype)
 .fail(function(){
})

The reason for setting the datatype as 'jsonp' is due to browser same origin policy issues, but if you are making the request on the same domain where your javascript is hosted, you should be fine with datatype set to json.

If you don't want to use the jquery $.get then see the docs for $.ajax which allows room for more flexibility

According to the Wordpress documentation, you should use wp_localize_script() in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.

See Codex

Example:

<?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>

To access this variable within in Javascript, you would simply do:

<script type="text/javascript">
    var url = WPURLS.siteurl;
</script>

The strategy of the accepted answer is correct, but here's a generalized example that works with the current version of React and Material-UI.

The flow of data should be one-way:

• the initialState is initialized in the constructor of the MyForm control
• the TextAreas are populated from this initial state
• changes to the TextAreas are propagated to the state via the handleChange callback.
• the state is accessed from the onClick callback---right now it just writes to the console. If you want to add validation it could go there.

import * as React from "react";
import TextField from "material-ui/TextField";
import RaisedButton from "material-ui/RaisedButton";

const initialState = {
    error: null, // you could put error messages here if you wanted
    person: {
        firstname: "",
        lastname: ""
    }
};

export class MyForm extends React.Component {

    constructor(props) {
        super(props);
        this.state = initialState;
        // make sure the "this" variable keeps its scope
        this.handleChange = this.handleChange.bind(this);
        this.onClick = this.onClick.bind(this);
    }

    render() {
        return (
            <div>
                <div>{this.state.error}</div>
                <div>
                    <TextField
                        name="firstname"
                        value={this.state.person.firstname}
                        floatingLabelText="First Name"
                        onChange={this.handleChange}/>
                    <TextField
                        name="lastname"
                        value={this.state.person.lastname}
                        floatingLabelText="Last Name"
                        onChange={this.handleChange}/>
                </div>
                <div>
                    <RaisedButton onClick={this.onClick} label="Submit!" />
                </div>
            </div>
        );
    }

    onClick() {
        console.log("when clicking, the form data is:");
        console.log(this.state.person);
    }

    handleChange(event, newValue): void {
        event.persist(); // allow native event access (see: https://facebook.github.io/react/docs/events.html)
        // give react a function to set the state asynchronously.
        // here it's using the "name" value set on the TextField
        // to set state.person.[firstname|lastname].            
        this.setState((state) => state.person[event.target.name] = newValue);

    }

}


React.render(<MyForm />, document.getElementById('app'));

(Note: You may want to write one handleChange callback per MUI Component to eliminate that ugly event.persist() call.)

This can also happen in case you have enabled ProGuard. In buildTypes set minifyEnabled false, shrinkResources false, useProguard false

You can view this dump from the UNIX console.

The path for the heap dump will be provided as a variable right after where you have placed the mentioned variable.

E.g.:

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${DOMAIN_HOME}/logs/mps"

You can view the dump from the console on the mentioned path.

Edit: Coming back to this answer after a year of security research, I realize it makes the rather unfortunate implication that you would ever actually compare plaintext passwords. Please don't. Use a secure one-way hash with a salt and a reasonable number of iterations. Consider using a library: this stuff is hard to get right!

Original answer: What about the fact that String.equals() uses short-circuit evaluation, and is therefore vulnerable to a timing attack? It may be unlikely, but you could theoretically time the password comparison in order to determine the correct sequence of characters.

public boolean equals(Object anObject) {
    if (this == anObject) {
        return true;
    }
    if (anObject instanceof String) {
        String anotherString = (String)anObject;
        int n = value.length;
        // Quits here if Strings are different lengths.
        if (n == anotherString.value.length) {
            char v1[] = value;
            char v2[] = anotherString.value;
            int i = 0;
            // Quits here at first different character.
            while (n-- != 0) {
                if (v1[i] != v2[i])
                    return false;
                i++;
            }
            return true;
        }
    }
    return false;
}

Well my 2 cents when it comes to the topic word 2007 docx, word 97-2004 doc, pdf and all other types of MS Office wishing to be "converted from y to z but in real they don't wanna be". In my experience so far, conversion with LibreOffice or OpenOffice can't be relied on. Though .doc documents tend to be better supported than word 2007's .docx. In general it's very hard to convert the .docx to .doc without breaking anything.

.docx also tend to be extremely useful for templating where .doc is not for being binary.

The conversion from .doc to PDF was most of the time quite reliable. If you can still influence the design or content of the word document then this might be satisfying, but in my situation documents were supplied from foreign companies where even after generating the .docx templates, in some scenario's, the generated .docx had to be slightly modified with supplement text before it was generated to a PDF.

WINDOWS BASED!

All this hiccup made me come to the conclusion that the only true reliable conversion method I found was using the COM class in PHP and let the MS Word or Excel Application do all the work for you. I'll just give an example on converting .docx to .doc and/or PDF. If you do not have MS Office installed, you can download a trial version of 60 days which would give you enough room for testing purposes.

the COM.net extension is by default commented out in the php.ini, just search for the line php_com_dotnet.dll and uncomment it like so

  extension=php_com_dotnet.dll

Restart the web server (IIS is not a pre, Apache will work just as well).

The code below is a demonstration on how easy it is.

  $word = new COM("Word.Application") or die ("Could not initialise Object.");
  // set it to 1 to see the MS Word window (the actual opening of the document)
  $word->Visible = 0;
  // recommend to set to 0, disables alerts like "Do you want MS Word to be the default .. etc"
  $word->DisplayAlerts = 0;
  // open the word 2007-2013 document 
  $word->Documents->Open('yourdocument.docx');
  // save it as word 2003
  $word->ActiveDocument->SaveAs('newdocument.doc');
  // convert word 2007-2013 to PDF
  $word->ActiveDocument->ExportAsFixedFormat('yourdocument.pdf', 17, false, 0, 0, 0, 0, 7, true, true, 2, true, true, false);
  // quit the Word process
  $word->Quit(false);
  // clean up
  unset($word);

This is just a small demonstration. I can just say that if it comes to conversion, this was the only real reliable option I could use and even recommend.

I think your example is a sensible approach, although you could simplify it slightly as:

@title = tokens[Title].strip! || tokens[Title] if tokens[Title]

Alternative you could put it on two lines:

@title = tokens[Title] || ''
@title.strip!

What even is ‘children’?

The React docs say that you can use props.children on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.

My simple explanation of what this.props.children does is that it is used to display whatever you include between the opening and closing tags when invoking a component.

A simple example:

Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no this keyword so just use props.children

const Picture = (props) => {
  return (
    <div>
      <img src={props.src}/>
      {props.children}
    </div>
  )
}

This component contains an <img> that is receiving some props and then it is displaying {props.children}.

Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component.

//App.js
render () {
  return (
    <div className='container'>
      <Picture key={picture.id} src={picture.src}>
          //what is placed here is passed as props.children  
      </Picture>
    </div>
  )
}

Instead of invoking the component with a self-closing tag <Picture /> if you invoke it will full opening and closing tags <Picture> </Picture> you can then place more code between it.

This de-couples the <Picture> component from its content and makes it more reusable.

Reference: A quick intro to React’s props.children

I add the following code to /root/.bashrc to run the code only once,

Please commit the container to the image before run this script, otherwise the 'docker_services' file will be created in the images and no service will be run.

if [ ! -e /var/run/docker_services ]; then
    echo "Starting services"
    service mysql start
    service ssh start
    service nginx start
    touch /var/run/docker_services
fi

The document.createEvent documentation says that "The createEvent method is deprecated. Use event constructors instead."

So you should use this method instead:

var clickEvent = new MouseEvent("click", {
    "view": window,
    "bubbles": true,
    "cancelable": false
});

and fire it on an element like this:

element.dispatchEvent(clickEvent);

as shown here.

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

I do recommend you to change the configuration of JDK used by NetBeans in netbeans.conf config file:

netbeans_jdkhome="C:\Program Files\Java\..."

Did you mean len(list1)-1?

If you're searching for other method, you can try list1.index(list1[-1]), but I don't recommend this one. You will have to be sure, that the list contains NO duplicates.

Note: Skip the part about CNAME yourdomain.com. (note the .) and the heroku addons:add "custom domains"

http://blog.heroku.com/archives/2009/10/7/heroku_casts_setting_up_custom_domains/

To summarize the video:

1) on GoDaddy and create a CNAME with

Alias Name: www
Host Name: proxy.heroku.com

2) check that your domain has propagated by typing host www.yourdomain.com on the command line

3) run heroku domains:add www.yourdomain.com

4) run heroku domains:add yourdomain.com

It worked for me after these steps. Hope it works for you too!

UPDATE: things have changed, check out this post Heroku/GoDaddy: send naked domain to www

This is the perfect code for uploading and displaying image through MySQL database.

<html>
<body>
<form method="post" enctype="multipart/form-data">
<input type="file" name="image"/>
<input type="submit" name="submit" value="Upload"/>
</form>
<?php
    if(isset($_POST['submit']))
    {
     if(getimagesize($_FILES['image']['tmp_name'])==FALSE)
     {
        echo " error ";
     }
     else
     {
        $image = $_FILES['image']['tmp_name'];
        $image = addslashes(file_get_contents($image));
        saveimage($image);
     }
    }
    function saveimage($image)
    {
        $dbcon=mysqli_connect('localhost','root','','dbname');
        $qry="insert into tablename (name) values ('$image')";
        $result=mysqli_query($dbcon,$qry);
        if($result)
        {
            echo " <br/>Image uploaded.";
            header('location:urlofpage.php');
        }
        else
        {
            echo " error ";
        }
    }
?>
</body>
</html>

If you want to uninstall when connected to single device/emulator then use below command

adb uninstall <package name>

else with multiple devices then use below command

adb -s <device ID> uninstall <package name>

You may use the typescript getter method for this scenario. Like this

public get width() {
  return window.innerWidth;
}

And use that in template like this:

<section [ngClass]="{ 'desktop-view': width >= 768, 'mobile-view': width < 768 
}"></section>

You won't need any event handler to check for resizing/ of window, this method will check for size every time automatically.

Exclude

Below code will retrieve all fields other than password within each document:

const users = await UserModel.find({}, {
  password: 0 
});
console.log(users);

Output

[
  {
    "_id": "5dd3fb12b40da214026e0658",
    "email": "[email protected]"
  }
]

Include

Below code will only retrieve email field within each document:

const users = await UserModel.find({}, {
  email: 1
});
console.log(users);

Output

[
  {
    "email": "[email protected]"
  }
]

Use this simple way hope it will helpful

foreach($array as $k => $value)
    {
      
        if($value == 'strawberry')
        {
          unset($array[$k]);
        }
    }

var upload = multer({dest: "./uploads"});
var mongo = require('mongodb');
var Grid = require("gridfs-stream");
Grid.mongo = mongo;

router.post('/:id', upload.array('photos', 200), function(req, res, next){
gfs = Grid(db);
var ss = req.files;
   for(var j=0; j<ss.length; j++){
     var originalName = ss[j].originalname;
     var filename = ss[j].filename;
     var writestream = gfs.createWriteStream({
         filename: originalName
     });
    fs.createReadStream("./uploads/" + filename).pipe(writestream);
   }
});

In your view:

<form action="/" method="post" enctype="multipart/form-data">
<input type="file" name="photos">

With this code you can add single as well as multiple images in MongoDB.

This works for me in Kotlin:

when(list.get(0)).thenThrow(new ArrayIndexOutOfBoundsException());

Note : Throw any defined exception other than Exception()

Greedy Quantifiers are like the IRS/ATO

If it’s there, they’ll take it all.

The IRS matches with this regex: .*

$50,000

This will match everything!

See here for an example: Greedy-example

Non-greedy quantifiers - they take as little as they can

If I ask for a tax refund, the IRS sudden becomes non-greedy, and they use this quantifier:

(.{2,5}?)([0-9]*) against this input: $50,000

The first group is non-needy and only matches $5 – so I get a $5 refund against the $50,000 input. They're non-greedy. They take as little as possible.

See here: Non-greedy-example.

Why bother?

It becomes important if you are trying to match certain parts of an expression. Sometimes you don't want to match everything.

Hopefully that analogy will help you remember!

I'm freshly new with Pandas but I wanted to achieve the same thing, automatically avoiding column names with _x or _y and removing duplicate data. I finally did it by using this answer and this one from Stackoverflow

sales.csv

    city;state;units
    Mendocino;CA;1
    Denver;CO;4
    Austin;TX;2

revenue.csv

    branch_id;city;revenue;state_id
    10;Austin;100;TX
    20;Austin;83;TX
    30;Austin;4;TX
    47;Austin;200;TX
    20;Denver;83;CO
    30;Springfield;4;I

merge.py import pandas

def drop_y(df):
    # list comprehension of the cols that end with '_y'
    to_drop = [x for x in df if x.endswith('_y')]
    df.drop(to_drop, axis=1, inplace=True)


sales = pandas.read_csv('data/sales.csv', delimiter=';')
revenue = pandas.read_csv('data/revenue.csv', delimiter=';')

result = pandas.merge(sales, revenue,  how='inner', left_on=['state'], right_on=['state_id'], suffixes=('', '_y'))
drop_y(result)
result.to_csv('results/output.csv', index=True, index_label='id', sep=';')

When executing the merge command I replace the _x suffix with an empty string and them I can remove columns ending with _y

output.csv

    id;city;state;units;branch_id;revenue;state_id
    0;Denver;CO;4;20;83;CO
    1;Austin;TX;2;10;100;TX
    2;Austin;TX;2;20;83;TX
    3;Austin;TX;2;30;4;TX
    4;Austin;TX;2;47;200;TX

Because XMLHttpReponse synchronous operation is deprecated I came up with the following solution that wraps XMLHttpRequest. This allows ordered AJAX queries while still being asycnronous in nature, which is very useful for single use CSRF tokens.

It is also transparent so libraries such as jQuery will operate seamlessly.

/* wrap XMLHttpRequest for synchronous operation */
var XHRQueue = [];
var _XMLHttpRequest = XMLHttpRequest;
XMLHttpRequest = function()
{
  var xhr   = new _XMLHttpRequest();
  var _send = xhr.send;

  xhr.send = function()
  {
    /* queue the request, and if it's the first, process it */
    XHRQueue.push([this, arguments]);
    if (XHRQueue.length == 1)
      this.processQueue();
  };

  xhr.processQueue = function()
  {
    var call = XHRQueue[0];
    var xhr  = call[0];
    var args = call[1];

    /* you could also set a CSRF token header here */

    /* send the request */
    _send.apply(xhr, args);
  };

  xhr.addEventListener('load', function(e)
  {
    /* you could also retrieve a CSRF token header here */

    /* remove the completed request and if there is more, trigger the next */
    XHRQueue.shift();
    if (XHRQueue.length)
      this.processQueue();
  });

  return xhr;
};

AssemblyInformationalVersion and AssemblyFileVersion are displayed when you view the "Version" information on a file through Windows Explorer by viewing the file properties. These attributes actually get compiled in to a VERSION_INFO resource that is created by the compiler.

AssemblyInformationalVersion is the "Product version" value. AssemblyFileVersion is the "File version" value.

The AssemblyVersion is specific to .NET assemblies and is used by the .NET assembly loader to know which version of an assembly to load/bind at runtime.

Out of these, the only one that is absolutely required by .NET is the AssemblyVersion attribute. Unfortunately it can also cause the most problems when it changes indiscriminately, especially if you are strong naming your assemblies.

... and Trick #3 Multiline entries in an Xtable

Generate some more data

moredata<-data.frame(Nominal=c(1:5), n=rep(5,5), 
        MeanLinBias=signif(rnorm(5, mean=0, sd=10), digits=4), 
        LinCI=paste("(",signif(rnorm(5,mean=-2, sd=5), digits=4),
                ", ", signif(rnorm(5, mean=2, sd=5), digits=4),")",sep=""),
        MeanQuadBias=signif(rnorm(5, mean=0, sd=10), digits=4), 
        QuadCI=paste("(",signif(rnorm(5,mean=-2, sd=5), digits=4),
                ", ", signif(rnorm(5, mean=2, sd=5), digits=4),")",sep=""))

names(moredata)<-c("Nominal", "n","Linear Model \nBias","Linear \nCI", "Quadratic Model \nBias", "Quadratic \nCI")

Now produce our xtable, using the sanitize function to replace column names with the correct Latex newline commands (including double backslashes so R is happy)

<<label=multilinetable, results=tex, echo=FALSE>>=
foo<-xtable(moredata)
align(foo) <- c( rep('c',3),'p{1.8in}','p{2in}','p{1.8in}','p{2in}' )
print(foo, 
            floating=FALSE, 
            include.rownames=FALSE,
            sanitize.text.function = function(str) {
                str<-gsub("\n","\\\\", str, fixed=TRUE)

                return(str)
            }, 
            sanitize.colnames.function = function(str) {
                str<-c("Nominal", "n","\\centering Linear Model\\\\ \\% Bias","\\centering Linear \\\\ 95\\%CI", "\\centering Quadratic Model\\\\ \\%Bias", "\\centering Quadratic \\\\ 95\\%CI \\tabularnewline")
                return(str)
            })
@  

(although this isn't perfect, as we need \tabularnewline so the table is formatted correctly, and Xtable still puts in a final \, so we end up with a blank line below the table header.)

You have to use an image to change the actual size or form of the bullet itself:

You can use a background image with appropriate padding to nudge content so it doesn't overlap:

list-style-image:url(bigger.gif);

or

background-image: url(images/bullet.gif);

You may try:

wget --user-agent=Mozilla --content-disposition --mirror --convert-links -E -K -p http://example.com/

Also you can add:

-A pdf,ps,djvu,tex,doc,docx,xls,xlsx,gz,ppt,mp4,avi,zip,rar

to accept the specific extensions, or to reject only specific extensions:

-R html,htm,asp,php

or to exclude the specific areas:

-X "search*,forum*"

If the files are ignored for robots (e.g. search engines), you've to add also: -e robots=off

See the below code (taken from this post)

Put this code in a Module in VBA (Developer Tab -> Visual Basic)

Dim TimerActive As Boolean
Sub StartTimer()
    Start_Timer
End Sub
Private Sub Start_Timer()
    TimerActive = True
    Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End Sub
Private Sub Stop_Timer()
    TimerActive = False
End Sub
Private Sub Timer()
    If TimerActive Then
        ActiveSheet.Cells(1, 1).Value = Time
        Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
    End If
End Sub

You can invoke the "StartTimer" function when the workbook opens and have it repeat every minute by adding the below code to your workbooks Visual Basic "This.Workbook" class in the Visual Basic editor.

Private Sub Workbook_Open()
    Module1.StartTimer
End Sub

Now, every time 1 minute passes the Timer procedure will be invoked, and set cell A1 equal to the current time.

1. apktool1.5.1.jar download from here.

2. apktool-install-linux-r05-ibot download from here.

3. dex2jar-0.0.9.15.zip download from here.

4. jd-gui-0.3.3.linux.i686.tar.gz (java de-complier) download from here.

5. framework-res.apk ( Located at your android device /system/framework/)

Procedure:

1. Rename the .apk file and change the extension to .zip ,

it will become .zip.

2. Then extract .zip.

3. Unzip downloaded dex2jar-0.0.9.15.zip file , copy the contents and paste it to unzip folder.

4. Open terminal and change directory to unzip “dex2jar-0.0.9.15 “

– cd – sh dex2jar.sh classes.dex (result of this command “classes.dex.dex2jar.jar” will be in your extracted folder itself).

5. Now, create new folder and copy “classes.dex.dex2jar.jar” into it.

6. Unzip “jd-gui-0.3.3.linux.i686.zip“ and open up the “Java Decompiler” in full screen mode.

7. Click on open file and select “classes.dex.dex2jar.jar” into the window.

8. “Java Decompiler” and go to file > save and save the source in a .zip file.

9. Create “source_code” folder.

10. Extract the saved .zip and copy the contents to “source_code” folder.

11. This will be where we keep your source code.

12. Extract apktool1.5.1.tar.bz2 , you get apktool.jar

13. Now, unzip “apktool-install-linux-r05-ibot.zip”

14. Copy “framework-res.apk” , “.apk” and apktool.jar

15. Paste it to the unzip “apktool-install-linux-r05-ibot” folder (line no 13).

16. Then open terminal and type:

    – cd

    – chown -R : ‘apktool.jar’

    – chown -R : ‘apktool’

    – chown -R : ‘aapt’

    – sudo chmod +x ‘apktool.jar’

    – sudo chmod +x ‘apktool’

    – sudo chmod +x ‘aapt’

    – sudo mv apktool.jar /usr/local/bin

    – sudo mv apktool /usr/local/bin

    – sudo mv aapt /usr/local/bin

    – apktool if framework-res.apk – apktool d .apk

You're using message.Length which returns the number of characters in the string, but you should be using the nubmer of bytes to read. You should use something like:

byte[] messageBytes = uniEncoding.GetBytes(message);
stringAsStream.Write(messageBytes, 0, messageBytes.Length);

You're then reading a single byte and expecting to get a character from it just by casting to char. UnicodeEncoding will use two bytes per character.

As Justin says you're also not seeking back to the beginning of the stream.

Basically I'm afraid pretty much everything is wrong here. Please give us the bigger picture and we can help you work out what you should really be doing. Using a StreamWriter to write and then a StreamReader to read is quite possibly what you want, but we can't really tell from just the brief bit of code you've shown.

Old post I know. In order to run your app always in portrait mode even when orientation may be or is swapped etc (for example on tablets) I designed this function that is used to set the device in the right orientation without the need to know how the portrait and landscape features are organised on the device.

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

Works like a charm!

NOTICE: Change this.activity by your activity or add it to the main activity and remove this.activity ;-)

I had the similar issue. Probably check if you are using proxy.

If yes, set up the proxy before doing download:

nltk.set_proxy('http://proxy.example.com:3128', ('USERNAME', 'PASSWORD'))

I think that you only have to replace SHA1 function with SHA256 function with tatk code from link in Your post

I've found a solution for this

Create a custom transparent dialog and inside that dialog open the popup window:

dialog = new Dialog(context, android.R.style.Theme_Translucent_NoTitleBar);
emptyDialog = LayoutInflater.from(context).inflate(R.layout.empty, null);

/* blur background*/
WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();  
lp.dimAmount=0.0f;  
dialog.getWindow().setAttributes(lp);  
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND); 
dialog.setContentView(emptyDialog);
dialog.setCanceledOnTouchOutside(true);
dialog.setOnShowListener(new OnShowListener()
{
    @Override
    public void onShow(DialogInterface dialogIx)
    {
        mQuickAction.show(emptyDialog); //open the PopupWindow here
    }
});
dialog.show();

xml for the dialog(R.layout.empty):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_height="match_parent" android:layout_width="match_parent"
     style="@android:style/Theme.Translucent.NoTitleBar" />

now you want to dismiss the dialog when Popup window dismisses. so

mQuickAction.setOnDismissListener(new OnDismissListener()
{
    @Override
    public void onDismiss()
    {
        if(dialog!=null)
        {
            dialog.dismiss(); // dismiss the empty dialog when the PopupWindow closes
            dialog = null;
        }
    }
});

Note: I've used NewQuickAction plugin for creating PopupWindow here. It can also be done on native Popup Windows

Browsers may differ, and you should also remember to not trust any info generated by the client, that being said, the below statement works for me (Google Chrome v24 on Mac OS X 10.8.2)

var utcDate = new Date(new Date().getTime());

edit: "How is this different than just new Date()?" see here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

• If no arguments are provided, the constructor creates a JavaScript Date object for the current date and time according to system settings.
• Note: Where Date is called as a constructor with more than one argument, the specifed arguments represent local time. If UTC is desired, use new Date(Date.UTC(...)) with the same arguments. (note: Date.UTC() returns the number of millisecond since 1970-01-01 00:00:00 UTC)

Adding the 60000 * Date.getTimezoneOffset() as previous answers have stated is incorrect. First, you must think of all Dates/Times as already being UTC with a timezone modifier for display purposes.

Again, browsers may differ, however, Date.getTime() returns the number of milliseconds since 1970-01-01 UTC/GMT. If you create a new Date using this number as I do above, it will be UTC/GMT. However, if you display it by calling .toString() it will appear to be in your local timezone because .toString() uses your local timezone, not the timezone of the Date object it is called on.

I have also found that if you call .getTimezoneOffset() on a date, it will return your local timezone, not the timezone of the date object you called it on (I can't verify this to be standard however).

In my browser, adding 60000 * Date.getTimezoneOffset() creates a DateTime that is not UTC. However when displayed within my browser (ex: .toString() ), it displays a DateTime in my local timezone that would be correct UTC time if timezone info is ignored.

namespace MyNamespace
{
    public class MyMainClass
    {
        static void Main()
        {
            MyClass test = new MyClass();
        }
    }

    public class MyClass
    {
        void Stuff()
        {

        }
    }
}

You have no need for using a namespace then because it is all encompased in the same namespace.

If you are unsure of what namespace your class is located, type the class (case sensitive you wish to use) then with your cursor on the class, use CTRL + . and it will offer you a manual import.

you may be create function before so, update your function again using.

     Where  dbo.RESTORANTET.ID_Rest=@emri_rest
     RETURN @rankimi
END
GO

SELECT dbo.Afisho_rankimin(5) AS Rankimi
GO

Maybe a simpler solution is to set an overlay in front of your map using FrameLayout or RelativeLayout and treating them as regular buttons in your activity. You should declare your layers in back to front order, e.g., map before buttons. I modified your layout, simplified it a little bit. Try the following layout and see if it works for you:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:scrollbars="vertical"  
        class="com.google.android.gms.maps.SupportMapFragment"/>

        android:id="@+id/radio_group_list_selector"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:orientation="horizontal" 
        android:background="#80000000"
        android:padding="4dp" >

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

Actually now you can use generics in Python 3.5+. See PEP-484 and typing module documentation.

According to my practice it is not very seamless and clear especially for those who are familiar with Java Generics, but still usable.

Disclaim: the following suggestion could be an overhead depending on the situation. The function is only tested with MSSQL 2008 R2 but seams be compatible to other versions

if you wane do this with many Id's you may could use a function which creates a temp table where you will be able to DELETE FROM the selection

how the query could look like:

-- not tested
-- @ids will contain a varchar with your ids e.g.'9 12 27 37'
DELETE FROM table WHERE id IN (SELECT i.number FROM iter_intlist_to_tbl(@ids))

here is the function:

ALTER FUNCTION iter_intlist_to_tbl (@list nvarchar(MAX))
   RETURNS @tbl TABLE (listpos int IDENTITY(1, 1) NOT NULL,
                       number  int NOT NULL) AS

Since Java7 you can simply use FileNameExtensionFilter(String description, String... extensions)

A simple JFileChooser analog to the example would be:

JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new FileNameExtensionFilter("Text files", "txt"));

I know the question was answered long ago, but this is actually the simplest solution.

double example = 3.1416789645;
double output = Convert.ToDouble(example.ToString("N3"));

Following two steps worked perfectly fine for me:

1. Comment out the bind address from the file /etc/mysql/my.cnf:

   #bind-address = 127.0.0.1

2. Run following query in phpMyAdmin:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;

Do you want something as simple like:

#include <unistd.h>
sleep(3);//sleeps for 3 second

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

What Harley said, except the last point - it's not actually necessary to change the '/'s into '\'s before calling open. Windows is quite happy to accept paths with forward slashes.

infile = open('c:/folder/subfolder/file.txt')

The only time you're likely to need the string normpathed is if you're passing to to another program via the shell (using os.system or the subprocess module).

I came here looking for tidyverse function name - which I knew existed. Adding this for (my) future reference and for tidyverse enthusiasts: purrrlyr:invoke_rows (purrr:invoke_rows in older versions).

With connection to standard stats methods as in the original question, the broom package would probably help.

Just add this to your view:

<?php header("Access-Control-Allow-Origin: *"); ?>

I needed to change architecture to x86 from x64 in configuration manager and copy my 32 bit dll (C language - pcProxAPI.dll) into new folder this created.. This is on top of the steps described by "Sashus" below.

To quote the great explanation of Eric

What happens? Do you want the list of giraffes to contain a tiger? Do you want a crash? or do you want the compiler to protect you from the crash by making the assignment illegal in the first place? We choose the latter.

But what if you want to choose for a runtime crash instead of a compile error? You would normally use Cast<> or ConvertAll<> but then you will have 2 problems: It will create a copy of the list. If you add or remove something in the new list, this won't be reflected in the original list. And secondly, there is a big performance and memory penalty since it creates a new list with the existing objects.

I had the same problem and therefore I created a wrapper class that can cast a generic list without creating an entirely new list.

In the original question you could then use:

class Test
{
    static void Main(string[] args)
    {
        A a = new C(); // OK
        IList<A> listOfA = new List<C>().CastList<C,A>(); // now ok!
    }
}

and here the wrapper class (+ an extention method CastList for easy use)

public class CastedList<TTo, TFrom> : IList<TTo>
{
    public IList<TFrom> BaseList;

    public CastedList(IList<TFrom> baseList)
    {
        BaseList = baseList;
    }

    // IEnumerable
    IEnumerator IEnumerable.GetEnumerator() { return BaseList.GetEnumerator(); }

    // IEnumerable<>
    public IEnumerator<TTo> GetEnumerator() { return new CastedEnumerator<TTo, TFrom>(BaseList.GetEnumerator()); }

    // ICollection
    public int Count { get { return BaseList.Count; } }
    public bool IsReadOnly { get { return BaseList.IsReadOnly; } }
    public void Add(TTo item) { BaseList.Add((TFrom)(object)item); }
    public void Clear() { BaseList.Clear(); }
    public bool Contains(TTo item) { return BaseList.Contains((TFrom)(object)item); }
    public void CopyTo(TTo[] array, int arrayIndex) { BaseList.CopyTo((TFrom[])(object)array, arrayIndex); }
    public bool Remove(TTo item) { return BaseList.Remove((TFrom)(object)item); }

    // IList
    public TTo this[int index]
    {
        get { return (TTo)(object)BaseList[index]; }
        set { BaseList[index] = (TFrom)(object)value; }
    }

    public int IndexOf(TTo item) { return BaseList.IndexOf((TFrom)(object)item); }
    public void Insert(int index, TTo item) { BaseList.Insert(index, (TFrom)(object)item); }
    public void RemoveAt(int index) { BaseList.RemoveAt(index); }
}

public class CastedEnumerator<TTo, TFrom> : IEnumerator<TTo>
{
    public IEnumerator<TFrom> BaseEnumerator;

    public CastedEnumerator(IEnumerator<TFrom> baseEnumerator)
    {
        BaseEnumerator = baseEnumerator;
    }

    // IDisposable
    public void Dispose() { BaseEnumerator.Dispose(); }

    // IEnumerator
    object IEnumerator.Current { get { return BaseEnumerator.Current; } }
    public bool MoveNext() { return BaseEnumerator.MoveNext(); }
    public void Reset() { BaseEnumerator.Reset(); }

    // IEnumerator<>
    public TTo Current { get { return (TTo)(object)BaseEnumerator.Current; } }
}

public static class ListExtensions
{
    public static IList<TTo> CastList<TFrom, TTo>(this IList<TFrom> list)
    {
        return new CastedList<TTo, TFrom>(list);
    }
}

PPK's script is THE authority for this kind of things, as @Jalpesh said, this might point you in the right way

var wn = window.navigator,
        platform = wn.platform.toString().toLowerCase(),
        userAgent = wn.userAgent.toLowerCase(),
        storedName;

// ie
    if (userAgent.indexOf('msie',0) !== -1) {
        browserName = 'ie';
        os = 'win';
        storedName = userAgent.match(/msie[ ]\d{1}/).toString();
        version = storedName.replace(/msie[ ]/,'');

        browserOsVersion = browserName + version;
    }

The source code for the Android mobile application open-gpstracker which you appreciated is available here.

You can checkout the code using SVN client application or via Git:

• svn checkout http://open-gpstracker.googlecode.com/svn/trunk/ open-gpstracker-read-only
• git clone https://code.google.com/p/open-gpstracker/

Debugging the source code will surely help you.

Suppose you have two moneyboxes, red and white. You assign these moneyboxes only two children and they are not allowed interchange their boxes. So You have red or white moneyboxes(final) you cannot modify the box but you can put money on your box.Nobody cares (Modification-2).

Use below code for IMEI:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
String imei= tm.getDeviceId();

Worth mentioning that there are many different solutions which offer two way binding and play really nicely.

I have had a pleasant experience with this model binder - https://github.com/theironcook/Backbone.ModelBinder. which gives sensible defaults yet a lot of custom jquery selector mapping of model attributes to input elements.

There is a more extended list of backbone extensions/plugins on github

I had similar issue. Earlier I was using Maven 3 to build the project. After switching to maven 2 , I had the above error.

Solved it by switching to Maven 3.

If you really want this by pulling branches instead of push --mirror, you can have a look here:

"fetch --all" in a git bare repository doesn't synchronize local branches to the remote ones

This answer provides detailed steps on how to achieve that relatively easily:

You can extend the gallery and use some flag to disable scrolling when you want:

public class MyGallery extends Gallery {

public boolean canScroll;

public MyGallery(Context context, AttributeSet attrs) {
    canScroll = true;
    super(context, attrs);
}

public void setCanScroll(boolean flag)
{
    canScroll = flag;
}

@Override
public boolean onScroll(android.view.MotionEvent e1, android.view.MotionEvent e2, float distanceX, float distanceY) {
    if (canScroll)
        return super.onScroll(e1,e2,distancex,distancey);
    else
        return false;
}

@Override
public boolean onSingleTapUp(MotionEvent e)
{
    if (canScroll)
        return super.onSingleTapUp(ey);
    else
        return false;
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
    if (canScroll)
        return super.onFling(e1,e2,velocityX,velocityY);
    else
        return false;
}
}

I got rid of this warning by changing the "Swift 3 @objc Inference" build setting of my targets to "Default".

From this article:

Before Swift 4, the compiler made some Swift declarations automatically available to Objective-C. For example, if one subclassed from NSObject, the compiler created Objective-C entry points for all methods in such classes. The mechanism is called @objc inference.

In Swift 4, such automatic @objc inference is deprecated because it is costly to generate all those Objective-C entry points. When "Swift 3 @objc Inference" setting is set to "On", it allows the old code to work. However, it will show deprecation warnings that need to be addressed. It is recommended to "fix" these warnings and switch the setting to "Default", which is the default for new Swift projects.

Please also refer to this Swift proposal for more information.

Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

pip install numpy==1.19.3

this did the job for me.

You want the list items to line up next to each other, but not really be inline elements. So float them instead:

ol.widgets li { 
    float: left;
    margin-left: 10px;
}

I would recommend giving Trackjs a try.

It's error logging as a service.

It's amazingly simple to set up. Just add one <script> line to each page and that's it. This also means it will be amazingly simple to remove if you decide you don't like it.

There are other services like Sentry (which is open-source if you can host your own server), but it doesn't do what Trackjs does. Trackjs records the user's interaction between their browser and your webserver so that you can actually trace the user steps that led to the error, as opposed to just a file and line number reference (and maybe stack trace).

Just add

<item name="colorControlNormal">@color/white</item> 

to your current app theme.

The one-liner solution is more useful as a shibboleth than good code; good Perl coders will know it and understand it, but it's much less transparent and readable than the two-line copy-and-modify couplet you're starting with.

In other words, a good way to do this is the way you're already doing it. Unnecessary concision at the cost of readability isn't a win.

Rails starting from version 5.2.3 has upcase_first method.

For example, "my Test string".upcase_first will return My Test string.

I'm using intelliJ 15 community edition and I'm able to right click a file and select 'add to .gitignore'

First make the button invisible in xml file.Then set button visible in java code if needed.

Button resetButton=(Button)findViewById(R.id.my_button_del);
resetButton.setVisibility(View.VISIBLE); //To set visible

Xml:

<Button
android:text="Delete"
android:id="@+id/my_button_del"
android:layout_width="72dp" 
android:layout_height="40dp"
android:visibility="invisible"/>

You can convert the list to a set. A set cannot have duplicates. So if all the elements in the original list are identical, the set will have just one element.

if len(set(input_list)) == 1:
    # input_list has all identical elements.

Use this function. Don't forget to save the WhatsApp Number on your mobile before sending trigger the function.

private void openWhatsApp() {
        Uri uri = Uri.parse("smsto:"+ "12345");
        Intent i = new Intent(Intent.ACTION_SENDTO,uri);
        i.setPackage("com.whatsapp");
        startActivity(i);
    }

In reality, pretty much never. All you're doing is suggesting that the compiler make a given function inline (e.g., replace all calls to this function /w its body). There are no guarantees, of course: the compiler may ignore the directive.

The compiler will generally do a good job of detecting + optimizing things like this.

• Download Xcode 4.6.x from the Apple Dev Center: https://developer.apple.com/downloads/index.action
• Create a folder called Xcode4 within the Applications folder and drag-n-drop the downloaded dmg there.

• Open a terminal window

You cannot simply add number to datetime because it's unclear what unit is used: seconds, hours, weeks...

There is timedelta class for manipulations with date and time. datetime minus datetime gives timedelta, datetime plus timedelta gives datetime, two datetime objects cannot be added although two timedelta can.

Create timedelta object with how many seconds you want to add and add it to datetime object:

>>> from datetime import datetime, timedelta
>>> t = datetime.now() + timedelta(seconds=3000)
>>> print(t)
datetime.datetime(2018, 1, 17, 21, 47, 13, 90244)

There is same concept in C++: std::chrono::duration.

You can use this Autoit script to handle the login popup:

If WinExists("Authentication Required") Then
Send("username{TAB}")
Send("Password{Enter}")

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Some modifications were made on posted answer UnderWaterKremlin to make it python3 proof. A surprising result below as answer.

System specs:

• python =3.7.4,
• conda = 4.8.0
• 3.6Ghz, 8 core, 16gb.

import timeit

d = {x: x**2 for x in range(1000)}
#print (d)
print (len(d))
# 1000

print (len(d.keys()))
# 1000

print (timeit.timeit('len({x: x**2 for x in range(1000)})', number=100000))        # 1

print (timeit.timeit('len({x: x**2 for x in range(1000)}.keys())', number=100000)) # 2

Result:

1) = 37.0100378

2) = 37.002148899999995

So it seems that len(d.keys()) is currently faster than just using len().

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Go to Anaconda Naviagator, find spyder,click settings in the top right corner of the spyder app.click update tab

Use dict.items(); it can be as simple as following:

ship = collections.OrderedDict(ship.items())

For MinGW this worked for me:

• Right click project, select Properties
• Go to C/C++ General - Paths and Symbols - Includes - GNU C++ - Include directories
• Select Add...
• Select Variables...
• Select MINGW_HOME and click OK
• Click Apply and OK

You should now see several MinGW paths in Includes in your project explorer.
The errors may not disappear instantly, you may need to refresh/build your project.

If you are using Cygwin, there could be an equivalent variable present.

iOS 11.x Swift 4.0 Info.plist needs these two properties

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>We're watching you</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Watch Out</string>

And this code ... making sure of course your a CLLocationManagerDelegate

let locationManager = CLLocationManager()

// MARK location Manager delegate code + more

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch status {
    case .notDetermined:
        print("User still thinking")
    case .denied:
        print("User hates you")
    case .authorizedWhenInUse:
            locationManager.stopUpdatingLocation()
    case .authorizedAlways:
            locationManager.startUpdatingLocation()
    case .restricted:
        print("User dislikes you")
    }

And of course this code too which you can put in viewDidLoad().

locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.distanceFilter = kCLDistanceFilterNone
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestLocation()

And these two for the requestLocation to get you going, aka save you having to get out of your seat :)

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
    print(error)
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    print(locations)

I am not experiented .But i think XmlReader is unnecessary. It is very hard to use.
XElement is very easy to use.
If you need performance ( faster ) you must change file format and use StreamReader and StreamWriter classes.

exampleLabel.text = String(yourInt)

This is a very interesting bug. (In my opinion, it is a bug anyway) Nice find!

Regarding how to set it, I would recommend Camilo Martin's answer. But as to why, I'd like to explain this a bit if you guys don't mind.

In the CSS specs I found:

'padding'
Percentages: refer to width of containing block

… which is weird, but okay.

So, with a parent width: 210px and a child padding-top: 50%, I get a calculated/computed value of padding-top: 96.5px – which is not the expected 105px.

That is because in Windows (I'm not sure about other OSs), the size of common scrollbars is per default 17px × 100% (or 100% × 17px for horizontal bars). Those 17px are substracted before calculating the 50%, hence 50% of 193px = 96.5px.

The answer given by Simon works fine for me but you have to do it in the right sequence: First you have to be in the server that you want to insert data into which is [DATABASE.WINDOWS.NET].[basecampdev] in your case.

You can try to see if you can select some data out of the Invoice table to make sure you have access.

Select top 10 * from [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]

Secondly, execute the query given by Simon in order to link to a different server. This time use the other server:

EXEC sp_addlinkedserver [BC1-PC]; -- this will create a link tempdb that you can access from where you are
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [BC1-PC].testdabse.dbo.invoice; -- Make a copy of the table and data that you can use
GO

Now just do your insert statement.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks])
SELECT [InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks] FROM MyInvoice

Hope this helps!

Probably port is already in use. I face similar issue when i first run react-native run-android and then npm start. I solve it like this: First, get the id of the process running in port 8081: sudo lsof -i :8081

If you want to return a File to be downloaded, specially if you want to integrate with some javascript libs of file upload/download, then the code bellow should do the job:

@GET
@Path("/{key}")
public Response download(@PathParam("key") String key,
                         @Context HttpServletResponse response) throws IOException {
    try {
        //Get your File or Object from wherever you want...
            //you can use the key parameter to indentify your file
            //otherwise it can be removed
        //let's say your file is called "object"
        response.setContentLength((int) object.getContentLength());
        response.setHeader("Content-Disposition", "attachment; filename="
                + object.getName());
        ServletOutputStream outStream = response.getOutputStream();
        byte[] bbuf = new byte[(int) object.getContentLength() + 1024];
        DataInputStream in = new DataInputStream(
                object.getDataInputStream());
        int length = 0;
        while ((in != null) && ((length = in.read(bbuf)) != -1)) {
            outStream.write(bbuf, 0, length);
        }
        in.close();
        outStream.flush();
    } catch (S3ServiceException e) {
        e.printStackTrace();
    } catch (ServiceException e) {
        e.printStackTrace();
    }
    return Response.ok().build();
}

A more structured way to get this is to use UriBuilder. This avoids direct string manipulation.

var builder = new UriBuilder(Request.Url.Scheme, Request.Url.Host, Request.Url.Port);

I had the same exact problem and found the solution through the use of larachat.

Here's how to fix it you need to have your homestead.yaml file settings correct. If you want to know how its done follow Jeffery Way tutorial on homestead 2.0 https://laracasts.com/lessons/say-hello-to-laravel-homestead-two.

Now to fix Input not specified issue you need to ssh into homestead box and type

serve domain.app /home/vagrant/Code/path/to/public/directory this will generate a serve script for nginx. You will need to do this everytime you switch projects.

He also discussed what I explained in this series https://laracasts.com/series/laravel-5-fundamentals/

It works for me in all the browsers:

document.onkeydown = function(){
  switch (event.keyCode){
        case 116 : //F5 button
            event.returnValue = false;
            event.keyCode = 0;
            return false;
        case 82 : //R button
            if (event.ctrlKey){ 
                event.returnValue = false;
                event.keyCode = 0;
                return false;
            }
    }
}

the complete know how, i have included a example of the triggers and sequence

create table temasforo(
idtemasforo NUMBER(5) PRIMARY KEY,
autor       VARCHAR2(50) NOT NULL,
fecha       DATE DEFAULT (sysdate),
asunto      LONG  );

create sequence temasforo_seq
  start with 1
  increment by 1
  nomaxvalue;

create or replace
trigger temasforo_trigger
  before insert on temasforo
  referencing OLD as old NEW as new
  for each row
  begin
      :new.idtemasforo:=temasforo_seq.nextval;
    end;

From a quick google search it seems that the problem is a file or url couldn't be found be the HTTPservice.

Here are the links where I found this information:

Ugly PHP!

The JSON_UNESCAPED_UNICODE|JSON_UNESCAPED_SLASHES must be default, not an (strange) option... How to say it to php-developers?

The default MUST be the most frequent use, and the (current) most widely used standards as UTF8. How many PHP-code fragments in the Github or other place need this exoctic "embedded in HTML" feature?

I think you would want to add an 'onSelect' event handler to the initialization of your datepicker so your code gets triggered when the user selects a date. Try it out on jsFiddle

$(document).ready(function(){
    // Datepicker
    $('#datepicker').datepicker({
        dateFormat: 'yy-mm-dd',
        inline: true,
        minDate: new Date(2010, 1 - 1, 1),
        maxDate:new Date(2010, 12 - 1, 31),
        altField: '#datepicker_value',
        onSelect: function(){
            var day1 = $("#datepicker").datepicker('getDate').getDate();                 
            var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1;             
            var year1 = $("#datepicker").datepicker('getDate').getFullYear();
            var fullDate = year1 + "-" + month1 + "-" + day1;
            var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
            $('#page_output').html(str_output);
        }
    });
});

Do simple compare > and <.

if (dateA>dateB && dateA<dateC)
    //do something

If you care only on time:

if (dateA.TimeOfDay>dateB.TimeOfDay && dateA.TimeOfDay<dateC.TimeOfDay)
    //do something

    <script type="text/javascript">
        $(window).on('load',function(){
            setTimeout(function(){ alert(" //show popup"); }, 5000); 
        });
    </script>

I could resolve it by overriding Configuration in MyContext through adding connection string to the DbContextOptionsBuilder:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        if (!optionsBuilder.IsConfigured)
        {
            IConfigurationRoot configuration = new ConfigurationBuilder()
               .SetBasePath(Directory.GetCurrentDirectory())
               .AddJsonFile("appsettings.json")
               .Build();
            var connectionString = configuration.GetConnectionString("DbCoreConnectionString");
            optionsBuilder.UseSqlServer(connectionString);
        }
    }

Real life use case

At a Java-heavy company we had a python project that needed to go into a Nexus artifact repository. Python doesn't really have binaries, so simply just wanted to .tar or .zip the python files and push. The repo already had maven integration, so we used <packaging>pom</packaging> designator with the maven assembly plugin to package the python project as a .zip and upload it.

The steps are outlined in this SO post

From the HTTP core module docs:

1. Directives with the "=" prefix that match the query exactly. If found, searching stops.
2. All remaining directives with conventional strings. If this match used the "^~" prefix, searching stops.
3. Regular expressions, in the order they are defined in the configuration file.
4. If #3 yielded a match, that result is used. Otherwise, the match from #2 is used.

Example from the documentation:

location  = / {
  # matches the query / only.
  [ configuration A ] 
}
location  / {
  # matches any query, since all queries begin with /, but regular
  # expressions and any longer conventional blocks will be
  # matched first.
  [ configuration B ] 
}
location /documents/ {
  # matches any query beginning with /documents/ and continues searching,
  # so regular expressions will be checked. This will be matched only if
  # regular expressions don't find a match.
  [ configuration C ] 
}
location ^~ /images/ {
  # matches any query beginning with /images/ and halts searching,
  # so regular expressions will not be checked.
  [ configuration D ] 
}
location ~* \.(gif|jpg|jpeg)$ {
  # matches any request ending in gif, jpg, or jpeg. However, all
  # requests to the /images/ directory will be handled by
  # Configuration D.   
  [ configuration E ] 
}

If it's still confusing, here's a longer explanation.

a) If you want 0 when value is null

SELECT isnull(PartNum,0) AS PartNumber, PartID
FROM Part

b) If you want 0 when value is null and otherwise 1

SELECT 
  (CASE
    WHEN PartNum IS NULL THEN 0
    ELSE 1
  END) AS PartNumber,
  PartID
FROM Part

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

This function, based on the work by Laurenz Albe at https://www.cybertec-postgresql.com/en/index-your-foreign-key/, list all the foreign keys with missing indexes. The size of the table is shown, as for small tables the scanning performance could be superior to the index one.

UPDATE
as you can see correct solution in Learning answer, In SQL server management 2014 you can
1.click on "Edit Top 200 Rows"
and then
2.clicking on "Show SQL Pane (ctrl+3)"
and
3.removing TOP (200) from select query

Refer to Shen Lance answer there is not a way to edit Result of select query. and the other answers is only for normal select and only for 200 records.

Using LINQ, ofcourse. The below code would give you dictionary of item as string, and the count of each item in your sourc list.

var item2ItemCount = list.GroupBy(item => item).ToDictionary(x=>x.Key,x=>x.Count());

\d*\.\d*

Explanation:

\d* - any number of digits

\. - a dot

\d* - more digits.

This will match 123.456, .123, 123., but not 123

If you want the dot to be optional, in most languages (don't know about jquery) you can use

\d*\.?\d*

How to show uncommitted changes in Git

The command you are looking for is git diff.

git diff - Show changes between commits, commit and working tree, etc

Here are some of the options it expose which you can use

git diff (no parameters)
Print out differences between your working directory and the index.

git diff --cached:
Print out differences between the index and HEAD (current commit).

git diff HEAD:
Print out differences between your working directory and the HEAD.

git diff --name-only
Show only names of changed files.

git diff --name-status
Show only names and status of changed files.

git diff --color-words
Word by word diff instead of line by line.

Here is a sample of the output for git diff --color-words:

I also had the same error .. I did this to fix it

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets" />

change to

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v12.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

and it's done.

Re: SQL DevErr:The Network Adapter could not establish the connection VenCode20 Posted: Dec 7, 2011 3:23 AM in response to: MehulDoshi Reply

This worked for me:

Open the "New/Select Database Connection" dialogue and try changing the connection type setting from "Basic" to "TNS" and then selecting the network alias (for me: "ORCL").

www.somedomain.com is the domain/host. The subdomain is an important part. www. is often used interchangeably with not having one, but that has to be set up as a rule (even if it's set by default) because they are not equivalent. Think of another subdomain, like mx.. That probably has a different target than www..

Given that, I'd advise not doing this sort of thing. That said, since you're asking I imagine you have a good reason.

Personally, I'd suggest special-casing www. for this.

string host = HttpContext.Current.Request.Url.GetComponents(UriComponents.HostAndPort, UriFormat.Unescaped);;

if (host.StartsWith("www."))
    return host.Substring(4);
else
    return host;

Otherwise, if you're really 100% sure that you want to chop off any subdomain, you'll need something a tad more complicated.

string host = ...;

int lastDot = host.LastIndexOf('.');

int secondToLastDot = host.Substring(0, lastDot).LastIndexOf('.');

if (secondToLastDot > -1)
    return host.Substring(secondToLastDot + 1);
else
    return host;

Getting the port is just like other people have said.

This should do the job

//get a reference to the canvas
var ctx = $('#canvas')[0].getContext("2d");

//draw a dot
ctx.beginPath();
ctx.arc(20, 20, 10, 0, Math.PI*2, true);
ctx.closePath();
ctx.fill();

I used the solution below to export all datagrid values to a text file, rather than using the column names you can use the column index instead.

foreach (DataGridViewRow row in xxxCsvDG.Rows)
{
    File.AppendAllText(csvLocation, row.Cells[0].Value + "," + row.Cells[1].Value + "," + row.Cells[2].Value + "," + row.Cells[3].Value + Environment.NewLine);
}

grep -Fxvf file1 file2

What the flags mean:

-F, --fixed-strings
              Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.    
-x, --line-regexp
              Select only those matches that exactly match the whole line.
-v, --invert-match
              Invert the sense of matching, to select non-matching lines.
-f FILE, --file=FILE
              Obtain patterns from FILE, one per line.  The empty file contains zero patterns, and therefore matches nothing.

Because I don't like to have duplicate files (log4j.properties in test and main), and I have quite many test classes, they each runwith SpringJUnit4ClassRunner class, so I have to customize it. This is what I use:

import java.io.FileNotFoundException;

import org.junit.runners.model.InitializationError;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.util.Log4jConfigurer;

public class MySpringJUnit4ClassRunner extends SpringJUnit4ClassRunner {

    static {
        String log4jLocation = "classpath:log4j-oops.properties";
        try {
            Log4jConfigurer.initLogging(log4jLocation);
        } catch (FileNotFoundException ex) {
            System.err.println("Cannot Initialize log4j at location: " + log4jLocation);
        }
    }

    public MySpringJUnit4ClassRunner(Class<?> clazz) throws InitializationError {
        super(clazz);
    }
}

When you use it, replace SpringJUnit4ClassRunner with MySpringJUnit4ClassRunner

@RunWith(MySpringJUnit4ClassRunner.class) 
@ContextConfiguration("classpath:conf/applicationContext.xml") 
public class TestOrderController {
    private Logger LOG = LoggerFactory.getLogger(this.getClass());

    private MockMvc mockMvc;
...
}

I used this single line of code to create a new UIImage which is scaled. Set the scale and orientation params to achieve what you want. The first line of code just grabs the image.

    // grab the original image
    UIImage *originalImage = [UIImage imageNamed:@"myImage.png"];
    // scaling set to 2.0 makes the image 1/2 the size. 
    UIImage *scaledImage = 
                [UIImage imageWithCGImage:[originalImage CGImage] 
                              scale:(originalImage.scale * 2.0)
                                 orientation:(originalImage.imageOrientation)];

In case the precision is not known until runtime, this other formatting option is useful:

>>> n = 9
>>> '%.*f' % (n, numvar)
'135.123456789'

A simple way that solve my problem was:

npm cache clear

npm or a process controlled by it is watching too many files. Updating max_user_watches on the build node can fix it forever. For debian put the following on terminal:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

If you want know how Increase the amount of inotify watchers only click on link.

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

if we use same page to add/edit via submit button like below

<input type="hidden" value="<?echo $_GET['edit_id'];?>" name="edit_id">

then we should not use

isset($_POST['edit_id'])

bcoz edit_id is set all the time whether it is add or edit page , instead we should use check below condition

!empty($_POST['edit_id'])

Context

If you

1. want to force all users to have LF line endings for text files and
2. you cannot ensure that all users change their git config,

you can do that starting with git 2.10. 2.10 or later is required, because 2.10 fixed the behavior of text=auto together with eol=lf. Source.

Solution

Put a .gitattributes file in the root of your git repository having following contents:

* text=auto eol=lf

Commit it.

Optional tweaks

You can also add an .editorconfig in the root of your repository to ensure that modern tooling creates new files with the desired line endings.

# EditorConfig is awesome: http://EditorConfig.org

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
end_of_line = lf
insert_final_newline = true

You certainly can define functions in script files (I then tend to load them through my Powershell profile on load).

First you need to check to make sure the function is loaded by running:

ls function:\ | where { $_.Name -eq "A1"  }

And check that it appears in the list (should be a list of 1!), then let us know what output you get!

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

You can test it by using this snipped code:

private static void Main(string[] args)
{
   int threadCount = 0;
   try
   {
      for (int i = 0; i < int.MaxValue; i ++)
      {
         new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
         threadCount ++;
      }
   }
   catch
   {
      Console.WriteLine(threadCount);
      Console.ReadKey(true);
   }
}

When looking for the max performance you run into a lot of issue and potential bottlenecks. Running a simple hello world test is not necessarily going to find them all.

Possible limitations include:

• Kernel socket limitations: look in /proc/sys/net for lots of kernel tuning..
• process limits: check out ulimit as others have stated here
• as your application grows in complexity, it may not have enough CPU power to keep up with the number of connections coming in. Use top to see if your CPU is maxed
• number of threads? I'm not experienced with threading, but this may come into play in conjunction with the previous items.

A way to look at this is to consider the level of risk or harm.

Are you building an app with no users, POC/MVP? Are you a startup who needs to get to market and test your app quickly? If yes, I would probably just implement the simplest solution and maintain focus on finding product-market-fit. Use localStorage as its often easier to implement.

Are you building a v2 of an app with many daily active users or an app that people/businesses are heavily dependent on. Would getting hacked mean little or no room for recovery? If so, I would take a long hard look at your dependencies and consider storing token information in an http-only cookie.

Using both localStorage and cookie/session storage have their own pros and cons.

As stated by first answer: If your application has an XSS vulnerability, neither will protect your user. Since most modern applications have a dozen or more different dependencies, it becomes increasingly difficult to guarantee that one of your application's dependencies is not XSS vulnerable.

If your application does have an XSS vulnerability and a hacker has been able to exploit it, the hacker will be able to perform actions on behalf of your user. The hacker can perform GET/POST requests by retrieving token from localStorage or can perform POST requests if token is stored in a http-only cookie.

The only down-side of the storing your token in local storage is the hacker will be able to read your token.

You want to install the development package, which is libssl-dev:

sudo apt-get install libssl-dev

Hope this helps.

How I load Icons: Using Visual Studio 2010: Go to the project properties, click Add Resource > Existing File, select your Icon.

You'll see that a Resources folder appeared. This was my problem, I had to click the loaded icon (in Resources directory), and set "Copy to Output Directory" to "Copy always". (was set "Do not copy").

Now simply do:

Icon myIcon = new Icon("Resources/myIcon.ico");

This question has been answered over and over again :-) but why not.

First using tput is more portable in modern environments than manually injecting ASCII codes through echo -E

Here's a quick bash function:

 say() {
     echo "$@" | sed \
             -e "s/\(\(@\(red\|green\|yellow\|blue\|magenta\|cyan\|white\|reset\|b\|u\)\)\+\)[[]\{2\}\(.*\)[]]\{2\}/\1\4@reset/g" \
             -e "s/@red/$(tput setaf 1)/g" \
             -e "s/@green/$(tput setaf 2)/g" \
             -e "s/@yellow/$(tput setaf 3)/g" \
             -e "s/@blue/$(tput setaf 4)/g" \
             -e "s/@magenta/$(tput setaf 5)/g" \
             -e "s/@cyan/$(tput setaf 6)/g" \
             -e "s/@white/$(tput setaf 7)/g" \
             -e "s/@reset/$(tput sgr0)/g" \
             -e "s/@b/$(tput bold)/g" \
             -e "s/@u/$(tput sgr 0 1)/g"
  }

Now you can use:

 say @b@green[[Success]] 

to get:

Notes on portability of tput

First time tput(1) source code was uploaded in September 1986

tput(1) has been available in X/Open curses semantics in 1990s (1997 standard has the semantics mentioned below).

So, it's (quite) ubiquitous.

Kotlin? Here we go:

android {

    // ... (compileSdkVersion, buildToolsVersion, etc)

    defaultConfig {

        // ... (applicationId, miSdkVersion, etc)

        kapt {
            arguments {
                arg("room.schemaLocation", "$projectDir/schemas")
            }
        }
    }

    buildTypes {
        // ... (buildTypes, compileOptions, etc)
    }
}

//...

Don't forget about plugin:

apply plugin: 'kotlin-kapt'

For more information about kotlin annotation processor please visit: Kotlin docs

You are allowed to use IDs that start with a digit in your HTML5 documents:

The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.

There are no other restrictions on what form an ID can take; in particular, IDs can consist of just digits, start with a digit, start with an underscore, consist of just punctuation, etc.

But querySelector method uses CSS3 selectors for querying the DOM and CSS3 doesn't support ID selectors that start with a digit:

In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit.

Use a value like b22 for the ID attribute and your code will work.

Since you want to select an element by ID you can also use .getElementById method:

document.getElementById('22')

The method boolean shouldOverrideUrlLoading(WebView view, String url) was deprecated in API 24. If you are supporting new devices you should use boolean shouldOverrideUrlLoading (WebView view, WebResourceRequest request).

You can use both by doing something like this:

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    newsItem.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            view.loadUrl(request.getUrl().toString());
            return true;
        }
    });
} else {
    newsItem.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    });
}

If you are using angular version 8 please run the below command to fix this issue.

ng update @angular/cli @angular/core

Add scrolling="no" attribute to the iframe.

It should be

Intent myIntent = new Intent(this, Katra_home.class);
startActivity(myIntent);

You have to use existing activity context to start new activity, new activity is not created yet, and you cannot use its context or call methods upon it.

not an enclosing class error is thrown because of your usage of this keyword. this is a reference to the current object — the object whose method or constructor is being called. With this you can only refer to any member of the current object from within an instance method or a constructor.

Katra_home.this is invalid construct

Using the client instead of resource:

s3 = boto3.client('s3')
bucket='bucket_name'
result = s3.list_objects(Bucket = bucket, Prefix='/something/')
for o in result.get('Contents'):
    data = s3.get_object(Bucket=bucket, Key=o.get('Key'))
    contents = data['Body'].read()
    print(contents)

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]

# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]

# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

I thought of just adding some points missing in above answers. This diagram taken from here clearly states the what's really going on.

If I state again the real purpose of

• Split: Improves the parallel processing by distributing the processing load across different nodes (Mappers), which would save the overall processing time.

• Combine: Shrinks the output of each Mapper. It would save the time spending for moving the data from one node to another.

• Sort (Shuffle & Sort): Makes it easy for the run-time to schedule (spawn/start) new reducers, where while going through the sorted item list, whenever the current key is different from the previous, it can spawn a new reducer.

why not simply eg

var newList = list1.Union(list2)/*.Distinct()*//*.ToList()*/;

oh ... according to the documentation you can leave out the .Distinct()

This method excludes duplicates from the return set

I think you could use TIMESTAMPDIFF(unit,datetime_expr1,datetime_expr2) something like

select * from MyTab T where
TIMESTAMPDIFF(MINUTE,T.runTime,NOW()) > 20

You can use the NSDecimalRound function

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

be attention, if path to browser have space (as example "...\Program Files (x86)...") you need add double quotes to value of param.

Example:

-Dwebdriver.firefox.bin="D:\Program Files (x86)\Mozilla Firefox\firefox.exe"

All has been run successfully when added double quotes.

As input and output streams are just start and end point, the solution is to temporary store data in byte array. So you must create intermediate ByteArrayOutputStream, from which you create byte[] that is used as input for new ByteArrayInputStream.

public void doTwoThingsWithStream(InputStream inStream, OutputStream outStream){ 
  //create temporary bayte array output stream
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  doFirstThing(inStream, baos);
  //create input stream from baos
  InputStream isFromFirstData = new ByteArrayInputStream(baos.toByteArray()); 
  doSecondThing(isFromFirstData, outStream);
}

Hope it helps.

Also, does Jenkins delete the artifacts after each build ? (not the archived artifacts, I know I can tell it to delete those)

No, Hudson/Jenkins does not, by itself, clear the workspace after a build. You might have actions in your build process that erase, overwrite, or move build artifacts from where you left them. There is an option in the job configuration, in Advanced Project Options (which must be expanded), called "Clean workspace before build" that will wipe the workspace at the beginning of a new build.

Remove the width:100%; declarations.

Block elements should take up the whole available width by default.

This should remove the first element, and then you can return the remaining:

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
    _x000D_
myarray.shift();_x000D_
alert(myarray);

As others have suggested, you could also use slice(1);

var myarray = ["item 1", "item 2", "item 3", "item 4"];_x000D_
  _x000D_
alert(myarray.slice(1));

go to the side project panel, right click on references -> add reference and find System.Windows.Forms

Any time some error like this occurs (some namespace you added is missing that is obviously there) the solution is probably this - adding a reference.

This is needed because your default project does not include everything because you probably wont need it so it saves space. A good practice is to exclude things you're not using.

Check if a modal is open

$('.modal:visible').length && $('body').hasClass('modal-open')

To attach an event listener

$(document).on('show.bs.modal', '.modal', function () {
    // run your validation... ( or shown.bs.modal )
});

Use the System.Environment class.

The methods

var value = System.Environment.GetEnvironmentVariable(variable [, Target])

and

System.Environment.SetEnvironmentVariable(variable, value [, Target])

will do the job for you.

The optional parameter Target is an enum of type EnvironmentVariableTarget and it can be one of: Machine, Process, or User. If you omit it, the default target is the current process.

Overview of the services used by all sessions provides the distionary view v$session(or gv$session for RAC databases) in the column SERVICE_NAME.

To limit the information to the connected session use the SID from the view V$MYSTAT:

select SERVICE_NAME from gv$session where sid in (
select sid from V$MYSTAT)

If the name is SYS$USERS the session is connected to a default service, i.e. in the connection string no explicit service_name was specified.

To see what services are available in the database use following queries:

select name from V$SERVICES;
select name from V$ACTIVE_SERVICES;

I offen manage css/js plugin with composer which install it under vendor. I symlink those to the web/bundles directory, that's let composer update bundles as needed.

exemple:

1 - symlink once at all (use command fromweb/bundles/

ln -sf vendor/select2/select2/dist/ select2

2 - use asset where needed, in twig template :

{{ asset('bundles/select2/css/fileinput.css) }}

To replace anything that starts with "text" until the last character:

text.+(.*)$

Example

text             hsjh sdjh sd          jhsjhsdjhsdj hsd
                                                      ^
                                                      last character

text.+(\ 123)

Example

text fuhfh283nfnd03no3 d90d3nd 3d 123 udauhdah au dauh ej2e
^                                   ^
From here                     To here

Try:

move "C:\files\*.txt" "C:\txt"

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1

http://developer.android.com/reference/android/content/Context.html#BIND_ABOVE_CLIENT

public static final int BIND_ABOVE_CLIENT -- Added in API level 14

Flag for bindService(Intent, ServiceConnection, int): indicates that the client application binding to this service considers the service to be more important than the app itself. When set, the platform will try to have the out of memory killer kill the app before it kills the service it is bound to, though this is not guaranteed to be the case.

Other flags of the same group are: BIND_ADJUST_WITH_ACTIVITY, BIND_AUTO_CREATE, BIND_IMPORTANT, BIND_NOT_FOREGROUND, BIND_WAIVE_PRIORITY.

Note that the meaning of BIND_AUTO_CREATE has changed in ICS, and old applications that don't specify BIND_AUTO_CREATE will automatically have the flags BIND_WAIVE_PRIORITY and BIND_ADJUST_WITH_ACTIVITY set for them.

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=40760

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

The easiest way if you have

<div ng-repeat="person in data | filter: query"></div>

Filtered data length

<div>{{ (data | filter: query).length }}</div>

You needed to do something like this for the makefile:

LDFLAGS='-ldl'
make install

That'll pass the linker flags from make through to the linker. Doesn't matter that the makefile was autogenerated.

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

Use jQuery. You need to capture the click event and then go on to the website.

$("#myHref").on('click', function() {_x000D_
  alert("inside onclick");_x000D_
  window.location = "http://www.google.com";_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<a href="#" id="myHref">Click me</a>

I work for a company with hundreds of developers who obviously need to check Kafka messages on a regular basis. Employees come and go and therefore we want to avoid the setup (dedicated SASL credentials, certificates, ACLs, ...) for each new employee.

Our platform teams operate a deployment of Kowl (https://github.com/cloudhut/kowl) so that everyone can access it without going through the usual setup. We also use it when developing locally using a docker-compose file.

You can use string.Compare

    lst.Where(x => string.Compare(x,"valueToCompare",StringComparison.InvariantCultureIgnoreCase)==0);

if you just want to check contains then use "Any"

  lst.Any(x => string.Compare(x,"valueToCompare",StringComparison.InvariantCultureIgnoreCase)==0)

You can do this easily manually for each column like this:

df['A_perc'] = df['A']/df['sum']

If you want to do this in one step for all columns, you can use the div method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):

ds.div(ds['sum'], axis=0)

And if you want this in one step added to the same dataframe:

>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')
          A         B         C         D       sum    A_perc    B_perc  \

For those using EF Core with ASP.NET Core v1.0.0 I had a similar problem and used the following commands to correct it (@DavidSopko's post pointed me in the right direction, but the details are slightly different for EF Core):

Update-Database <Name of last good migration>
Remove-Migration

For example, in my current development the command became

PM> Update-Database CreateInitialDatabase
Done.
PM> Remove-Migration
Done.
PM> 

The Remove-Migration will remove the last migration you applied. If you have a more complex scenario with multiple migrations to remove (I only had 2, the initial and the bad one), I suggest you test the steps in a dummy project.

There doesn't currently appear to be a Get-Migrations command in EF Core (v1.0.0) so you must look in your migrations folder and be familiar with what you have done. However, there is a nice help command:

PM> get-help entityframework

Refreshing dastabase in VS2015 SQL Server Object Explorer, all of my data was preserved and the migration that I wanted to revert was gone :)

Initially I tried Remove-Migration by itself and found the error command confusing:

System.InvalidOperationException: The migration '...' has already been applied to the database. Unapply it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.

There are already suggestions on improving this wording, but I'd like the error to say something like this:

Run Update-Database (last good migration name) to revert the database schema back to to that state. This command will unapply all migrations that occurred after the migration specified to Update-Database. You may then run Remove-Migration (migration name to remove)

Output from the EF Core help command follows:

 PM> get-help entityframework
                     _/\__
               ---==/    \\
         ___  ___   |.    \|\
        | __|| __|  |  )   \\\
        | _| | _|   \_/ |  //|\\
        |___||_|       /   \\\/\\

LONG DESCRIPTION
    This topic describes the Entity Framework Core commands. See https://docs.efproject.net for information on Entity Framework Core.

    The following Entity Framework cmdlets are included.

        Cmdlet                      Description
        --------------------------  ---------------------------------------------------
        Add-Migration               Adds a new migration.

        Remove-Migration            Removes the last migration.

        Scaffold-DbContext          Scaffolds a DbContext and entity type classes for a specified database.

        Script-Migration            Generates a SQL script from migrations.

        Update-Database             Updates the database to a specified migration.

        Use-DbContext               Sets the default DbContext to use.

We can convert ararylist to array using 3 mrthod

1. public Object[] toArray() - it will return array of object

   Object[] array = list.toArray();

2. public T[] toArray(T[] a) - In this way we will create array and toArray Take it as argument then return it

      String[] arr = new String[list.size()]; 
       arr = list.toArray(arr);
   

3. Public get() method;

   Iterate ararylist and one by one add element in array.

Although it might look out of topic nobody bothered to check the ERRORLEVEL. When I used your suggestions I tried to check for errors straight after the MSI installation. I made it fail on purpose and noticed that on the command line all works beautifully whilst in a batch file msiexec dosn't seem to set errors. Tried different things there like

• Using start /wait
• Using !ERRORLEVEL! variable instead of %ERRORLEVEL%
• Using SetLocal EnableDelayedExpansion

Nothing works and what mostly annoys me it's the fact that it works in the command line.

if you don't want to create a UDF in VBA or you can't, this could be an alternative.

=Cell("Filename",A1) this will give you the full file name, and from this you could get the user name with something like this:

=Mid(A1,Find("\",A1,4)+1;Find("\";A1;Find("\";A1;4))-2)

This Formula runs only from a workbook saved earlier.

You must start from 4th position because of the first slash from the drive.

You must set your query base to the DN of the user in question, then set your filter to the DN of the group you're wondering if they're a member of. To see if jdoe is a member of the office group then your query will look something like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host '(memberof=cn=officegroup,dc=example,dc=local)'

If you want to see ALL the groups he's a member of, just request only the 'memberof' attribute in your search, like this:

ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host **memberof**

This one works for me it's not in one line but i hope it works for you.

<div>
<img src="attachment:image.png" width="500" height="300"/>
</div>

This seems to work fine, even with subdirectories:

find . -type f | xargs ls -ltr | tail -n 1

In case of too many files, refine the find.

If you are storing the type in your text (as you should be in this scenario), you can use the JsonSerializerSettings.

See: how to deserialize JSON into IEnumerable<BaseType> with Newtonsoft JSON.NET

Be careful, though. Using anything other than TypeNameHandling = TypeNameHandling.None could open yourself up to a security vulnerability.

Java 1.8 (as well as Groovy and Scala) has a thing called "Interface Defender Methods", which are interfaces with pre-defined default method bodies. By implementing multiple interfaces that use defender methods, you could effectively, in a way, extend the behavior of two interface objects.

Also, in Groovy, using the @Delegate annotation, you can extend behavior of two or more classes (with caveats when those classes contain methods of the same name). This code proves it:

class Photo {
    int width
    int height
}    
class Selection {
    @Delegate Photo photo    
    String title
    String caption
}    
def photo = new Photo(width: 640, height: 480)
def selection = new Selection(title: "Groovy", caption: "Groovy", photo: photo)
assert selection.title == "Groovy"
assert selection.caption == "Groovy"    
assert selection.width == 640
assert selection.height == 480
