If you are using Logback, just put this logback-test.xml file into src/test/resources directory:

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>
<root level="INFO">
    <appender-ref ref="STDOUT" />
</root>
</configuration>

I encountered the same problem, and I fix it by creating a new subclass of UIButton and overriding the layoutSubviews: method as below :

-(void)layoutSubviews {
    [super layoutSubviews];

    // Center image
    CGPoint center = self.imageView.center;
    center.x = self.frame.size.width/2;
    center.y = self.imageView.frame.size.height/2;
    self.imageView.center = center;

    //Center text
    CGRect newFrame = [self titleLabel].frame;
    newFrame.origin.x = 0;
    newFrame.origin.y = self.imageView.frame.size.height + 5;
    newFrame.size.width = self.frame.size.width;

    self.titleLabel.frame = newFrame;
    self.titleLabel.textAlignment = UITextAlignmentCenter;

}

I think that the Angel García Olloqui's answer is another good solution, if you place all of them manually with interface builder but I'll keep my solution since I don't have to modify the content insets for each of my button.

Make sure the function is in the same DB schema as the table.

The asker should use STAS answer, but for readers who use prism and no galasoft/mvvmlight, they may want to try what I used:

In the definition at the top for window or usercontrol, etc define namespace:

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

And just below that definition:

<i:Interaction.Triggers>
        <i:EventTrigger EventName="Closing">
            <i:InvokeCommandAction Command="{Binding WindowClosing}" CommandParameter="{Binding}" />
        </i:EventTrigger>
</i:Interaction.Triggers>

Property in your viewmodel:

public ICommand WindowClosing { get; private set; }

Attach delegatecommand in your viewmodel constructor:

this.WindowClosing = new DelegateCommand<object>(this.OnWindowClosing);

Finally, your code you want to reach on close of the control/window/whatever:

private void OnWindowClosing(object obj)
        {
            //put code here
        }

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

Maybe you should try it with -quality 100 -size "1024x1024", because resize often gives results that are ugly to view.

I have replaced the printf calls with calls to warning in the C-code now. It will be effective in the version 2.17.2 which should be available tomorrow night. Then you should be able to avoid the warnings with suppressWarnings() or any of the other above mentioned methods.

suppressWarnings({ your code })

After trying out the other solutions and still not getting it to work, I found out what the problem was in my case. I changed contentType from "application/json" to "text/plain".

$.ajax(fullUrl, {
    type: "GET",
    contentType: "text/plain",
    xhrFields: {
         withCredentials: true
    },
    crossDomain: true
});

If you are making scripts that are interchangeable with other utilities, below flexibility may be useful.

Either:

command -x=myfilename.ext --another_switch 

Or:

command -x myfilename.ext --another_switch

Here is the code:

STD_IN=0

prefix=""
key=""
value=""
for keyValue in "$@"
do
  case "${prefix}${keyValue}" in
    -i=*|--input_filename=*)  key="-i";     value="${keyValue#*=}";; 
    -ss=*|--seek_from=*)      key="-ss";    value="${keyValue#*=}";;
    -t=*|--play_seconds=*)    key="-t";     value="${keyValue#*=}";;
    -|--stdin)                key="-";      value=1;;
    *)                                      value=$keyValue;;
  esac
  case $key in
    -i) MOVIE=$(resolveMovie "${value}");  prefix=""; key="";;
    -ss) SEEK_FROM="${value}";          prefix=""; key="";;
    -t)  PLAY_SECONDS="${value}";           prefix=""; key="";;
    -)   STD_IN=${value};                   prefix=""; key="";; 
    *)   prefix="${keyValue}=";;
  esac
done

There is no portable function that allows to check if a key is hit and continue if not. This is always system dependent.

Solution for linux and other posix compliant systems:

Here, for Morgan Mattews's code provide kbhit() functionality in a way compatible with any POSIX compliant system. He uses the trick of desactivating buffering at termios level.

Solution for windows:

For windows, Microsoft offers _kbhit()

you can use redis-cli INFO keyspace

localhost:8000> INFO keyspace
# Keyspace
db0:keys=7,expires=0,avg_ttl=0
db1:keys=1,expires=0,avg_ttl=0
db2:keys=1,expires=0,avg_ttl=0
db11:keys=1,expires=0,avg_ttl=0

You need to use Range and Value functions.
Range would be the cell where you want the text you want
Value would be the text that you want in that Cell

Range("A1").Value="whatever text"

Query has two syntax, the syntax you are using, last column represents orderBy, you just need to specify on what column you want to do orderBy +"ASC" (or) orderBy +"DESC"

Cursor c = scoreDb.query(DATABASE_TABLE, rank, null, null, null, null, yourColumn+" DESC"); 

Refer this documentation to understand more about query() method.

You didn't hear it from me, the PM for Razor, but in Razor 2 (Web Pages 2 and MVC 4) we'll have conditional attributes built into Razor(as of MVC 4 RC tested successfully), so you can just say things like this...

<input type="text" id="@strElementID" class="@strCSSClass" />

If strCSSClass is null then the class attribute won't render at all.

SSSHHH...don't tell. :)

Variables are available only in the scope you defined them. If you define a variable inside a function, you won't be able to access it outside of it.

Define variable with var outside the function (and of course before it) and then assign 10 to it inside function:

var value;
$(function() {
  value = "10";
});
console.log(value); // 10

Note that you shouldn't omit the first line in this code (var value;), because otherwise you are assigning value to undefined variable. This is bad coding practice and will not work in strict mode. Defining a variable (var variable;) and assigning value to a variable (variable = value;) are two different things. You can't assign value to variable that you haven't defined.

It might be irrelevant here, but $(function() {}) is a shortcut for $(document).ready(function() {}), which executes a function as soon as document is loaded. If you want to execute something immediately, you don't need it, otherwise beware that if you run it before DOM has loaded, value will be undefined until it has loaded, so console.log(value); placed right after $(function() {}) will return undefined. In other words, it would execute in following order:

var value;
console.log(value);
value = "10";

Before clear space (trim)

Then replace with RegEx .replace("/\xEF\xBB\xBF/", "")

I'm working on Javascript, I did with JavaScript.

If you are trying to delete empty spaces , try using ='' instead of is null. Hence , if your row contains empty spaces , is null will not capture those records. Empty space is not null and null is not empty space.

Dec  Hex     Binary    Char-acter Description
0    00  00000000      NUL        null

32  20  00100000      Space       space

So I recommend:

delete  from foo_table  where bar = ''

#or 

delete  from foo_table  where bar = '' or bar is null 

#or even better , 

delete from foo_table where rtrim(ltrim(isnull(bar,'')))='';

I think all these answers are missing the question. The problem was to "Round UP", not just "Round". It is my understanding that Round Up means that ANY fractional value about a whole digit rounds up to the next WHOLE digit. ie: 48.0000000 = 48 but 25.00001 = 26. Is this not the definition of rounding up? (or have my past 60 years in accounting been misplaced?

The issue occurred in my case because spring framework couldn't fetch the properties of nested objects. Getters/Setters is one way of solving. Making the properties public is another quick and dirty solution to validate if this is indeed the problem.

If you want to use this answer, I found out that when you are using MacDown on MacOs, you can <div style="text-align: justify"> at the beginning of the document to justify all text and keep all code formating. Maybe it works on other editors too, for you to try ;)

You can also use Select-Object like so:

Get-ChildItem "C:\WINDOWS\System32" *.txt -Recurse | Select-Object FullName

For me it only fetched new dependencies from Docker Hub with both --no-cache and --pull (which are available for docker-compose build.

# other steps before rebuild
docker-compose build --no-cache --pull nginx # rebuild nginx
# other steps after rebuild, e.g. up (see other answers)

1. set the classpath and compile

   javac -classpath "C:\Program Files\Java\jdk1.6.0_updateVersion\tools.jar" yourApp.java

2. create manifest.txt

   Main-Class: yourApp newline

3. create yourApp.jar

   jar cvf0m yourApp.jar manifest.txt yourApp.class

4. run yourApp.jar

   java -jar yourApp.jar

Here's a little script that I use to switch between recent branches:

#!/bin/bash
# sudo bash

re='^[0-9]+$'

if [[ "$1" =~ $re ]]; then
    lines="$1"
else
    lines=10
fi
branches="$(git recent | tail -n $lines | nl)"
branches_nf="$(git recent-nf | tail -n $lines | nl)"
echo "$branches"

# Prompt which server to connect to
max="$(echo "$branches" | wc -l)"
index=
while [[ ! ( "$index" =~ ^[0-9]+$ && "$index" -gt 0 && "$index" -le "$max" ) ]]; do
    echo -n "Checkout to: "
    read index
done

branch="$( echo "$branches_nf" | sed -n "${index}p" | awk '{ print $NF }' )"
git co $branch
clear

Using those two aliases:

recent = for-each-ref --sort=committerdate refs/heads/ --format=' %(color:blue) %(authorname) %(color:yellow)%(refname:short)%(color:reset)'
recent-nf = for-each-ref --sort=committerdate refs/heads/ --format=' %(authorname) %(refname:short)'

Just call that in a Git repository, and it will show you the last N branches (10 by default) and a number aside each. Input the number of the branch, and it checks out:

No body mentioned rpl? Using rpl you can replace any string. To convert tabs to spaces,

rpl -R -e "\t" "    "  .

very simple.

Bind a change handler, then just uncheck all of the checkboxes, apart from the one checked:

$('input.example').on('change', function() {
    $('input.example').not(this).prop('checked', false);  
});

Here's a fiddle

Tray this short way

  var lower = (str+"").toLowerCase();

I found this implementation very easy to use. Also has a generous BSD-style license:

jsSHA: https://github.com/Caligatio/jsSHA

I needed a quick way to get the hex-string representation of a SHA-256 hash. It only took 3 lines:

var sha256 = new jsSHA('SHA-256', 'TEXT');
sha256.update(some_string_variable_to_hash);
var hash = sha256.getHash("HEX");

Open angular.json file

1.change from

"schematics": {}

to

"schematics": {
           "@schematics/angular:component": {
                   "styleext": "scss"       
             }  
  }

2. change from (at two places)

"src/styles.css"

to

"src/styles.scss"

then check and rename all .css files and update component.ts files styleUrls from .css to .scss

If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

If you wish more look at: http://developer.android.com/intl/pt-br/guide/topics/resources/string-resource.html#FormattingAndStyling

function go(type, pageCount) {
    if ((type == 2 && pageCount == 0) || (type == 2 && pageCount == '')) {
        pageCount = document.getElementById('<%=hfPageCount.ClientID %>').value;
    }
}

<script>
    $.getJSON('http://www.whateverorigin.org/get?url=' + encodeURIComponent('hhttps://example.com/') + '&callback=?', function (data) {
        alert(data.contents);
    });

</script>

Include jQuery and use this code to get HTML of other website. Replace example.com with your website.

This method involves an external server fetching the sites HTML & sending it to you. :)

In PySpark(python) one of the option is to have the column in unix_timestamp format.We can convert string to unix_timestamp and specify the format as shown below. Note we need to import unix_timestamp and lit function

from pyspark.sql.functions import unix_timestamp, lit

df.withColumn("tx_date", to_date(unix_timestamp(df_cast["date"], "MM/dd/yyyy").cast("timestamp")))

Now we can apply the filters

df_cast.filter(df_cast["tx_date"] >= lit('2017-01-01')) \
       .filter(df_cast["tx_date"] <= lit('2017-01-31')).show()

Making your own itoa is also easy, try this :

char* itoa(int i, char b[]){
    char const digit[] = "0123456789";
    char* p = b;
    if(i<0){
        *p++ = '-';
        i *= -1;
    }
    int shifter = i;
    do{ //Move to where representation ends
        ++p;
        shifter = shifter/10;
    }while(shifter);
    *p = '\0';
    do{ //Move back, inserting digits as u go
        *--p = digit[i%10];
        i = i/10;
    }while(i);
    return b;
}

or use the standard sprintf() function.

<View
       android:id="@+id/view"
       android:layout_width="match_parent"
       android:layout_height="2dp"
       android:background="#000000" />

You can do that with Guava's Splitter.MapSplitter:

Map<String, String> properties = Splitter.on(",").withKeyValueSeparator(":").split(inputString);

You can use Google's Gson library to convert json to Hashmap. Try below code

String jsonString = "Your JSON string";
HashMap<String,String> map = new Gson().fromJson(jsonString, new TypeToken<HashMap<String, String>>(){}.getType());

Try to use this code to handle server disconnect:

var db_config = {
  host: 'localhost',
    user: 'root',
    password: '',
    database: 'example'
};

var connection;

function handleDisconnect() {
  connection = mysql.createConnection(db_config); // Recreate the connection, since
                                                  // the old one cannot be reused.

  connection.connect(function(err) {              // The server is either down
    if(err) {                                     // or restarting (takes a while sometimes).
      console.log('error when connecting to db:', err);
      setTimeout(handleDisconnect, 2000); // We introduce a delay before attempting to reconnect,
    }                                     // to avoid a hot loop, and to allow our node script to
  });                                     // process asynchronous requests in the meantime.
                                          // If you're also serving http, display a 503 error.
  connection.on('error', function(err) {
    console.log('db error', err);
    if(err.code === 'PROTOCOL_CONNECTION_LOST') { // Connection to the MySQL server is usually
      handleDisconnect();                         // lost due to either server restart, or a
    } else {                                      // connnection idle timeout (the wait_timeout
      throw err;                                  // server variable configures this)
    }
  });
}

handleDisconnect();

In your code i am missing the parts after connection = mysql.createConnection(db_config);

If you want to retrieve the key's value if it exists, you can also use

try:
    value = a[key]
except KeyError:
    # Key is not present
    pass

If you want to retrieve a default value when the key does not exist, use value = a.get(key, default_value). If you want to set the default value at the same time in case the key does not exist, use value = a.setdefault(key, default_value).

The following adds one line after SearchPattern.

sed -i '/SearchPattern/aNew Text' SomeFile.txt

It inserts New Text one line below each line that contains SearchPattern.

To add two lines, you can use a \ and enter a newline while typing New Text.

POSIX sed requires a \ and a newline after the a sed function. [1] Specifying the text to append without the newline is a GNU sed extension (as documented in the sed info page), so its usage is not as portable.

One more little tidbit that I just discovered. (This may be so basic that some haven't mentioned it, but it was important for my solution.) The "packages" folder ends up in the same folder as your .sln file.

We moved our .sln file and then fixed all of the paths inside to find the various projects and voila! Our packages folder ended up where we wanted it.

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

Locate config.inc.php file under C:\xampp\phpMyAdmin and open it in any editor. Find the following line:

$cfg['Servers'][$i]['password'] = '  ';

Enter the chosen password inside the quotes. Also, in order to make localhost/phpmyadmin ask for a username and password, find the following line:

$cfg['Servers'][$i]['auth_type'] = 'config';

Change the above line to:

$cfg['Servers'][$i]['auth_type'] = 'cookie';

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

With rails + arel, a more clear way:

# Table name: messages
#
# sender_id:    integer
# recipient_id: integer
# content:      text

class Message < ActiveRecord::Base
  scope :by_participant, ->(user_id) do
    left  = arel_table[:sender_id].eq(user_id)
    right = arel_table[:recipient_id].eq(user_id)

    where(Arel::Nodes::Or.new(left, right))
  end
end

Produces:

$ Message.by_participant(User.first.id).to_sql 
=> SELECT `messages`.* 
     FROM `messages` 
    WHERE `messages`.`sender_id` = 1 
       OR `messages`.`recipient_id` = 1

Alternatively, you can bring variables in from the outside scope by using closures with the use keyword.

$myVar = "foo";
$myFunction = function($arg1, $arg2) use ($myVar)
{
 return $arg1 . $myVar . $arg2;
};

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

<merge/> is useful because it can get rid of unneeded ViewGroups, i.e. layouts that are simply used to wrap other views and serve no purpose themselves.

For example, if you were to <include/> a layout from another file without using merge, the two files might look something like this:

layout1.xml:

<FrameLayout>
   <include layout="@layout/layout2"/>
</FrameLayout>

layout2.xml:

<FrameLayout>
   <TextView />
   <TextView />
</FrameLayout>

which is functionally equivalent to this single layout:

<FrameLayout>
   <FrameLayout>
      <TextView />
      <TextView />
   </FrameLayout>
</FrameLayout>

That FrameLayout in layout2.xml may not be useful. <merge/> helps get rid of it. Here's what it looks like using merge (layout1.xml doesn't change):

layout2.xml:

<merge>
   <TextView />
   <TextView />
</merge>

This is functionally equivalent to this layout:

<FrameLayout>
   <TextView />
   <TextView />
</FrameLayout>

but since you are using <include/> you can reuse the layout elsewhere. It doesn't have to be used to replace only FrameLayouts - you can use it to replace any layout that isn't adding something useful to the way your view looks/behaves.

For the benefit of searchers, there is another way you can produce this error message - by missing the $ off the script block name when calling it.

e.g. I had a script block like so:

$qa = {
    param($question, $answer)
    Write-Host "Question = $question, Answer = $answer"
}

I tried calling it using:

&qa -question "Do you like powershell?" -answer "Yes!"

But that errored. The correct way was:

&$qa -question "Do you like powershell?" -answer "Yes!"

Both the right answer. HTML5 follows strict rules and in HTML5 we can close all the tags. So, it depends on you to use HTML5 or HTML and follow an appropriate answer.

<img src='stackoverflow.png'>
<img src='stackoverflow.png' />

The second property is more appropriate.

For those who just want to track if js was enabled, how about using an ajax routine to store the state? For example, I log all visitors/visits in a set of tables. The JSenabled field can be set to a default of FALSE, and the ajax routine would set it to TRUE, if JS is enabled.

Method overloading is a compile time polymorphism, let's take an example to understand the concept.

class Person                                            //person.java file
{
    public static void main ( String[] args )
    {
      Eat e = new Eat();
       e.eat(noodle);                                //line 6
    }

   void eat (Noodles n)      //Noodles is a object    line 8                     
   {

   }
   void eat ( Pizza p)           //Pizza is a object
  {

  }

}

In this example, Person has a eat method which represents that he can either eat Pizza or Noodles. That the method eat is overloaded when we compile this Person.java the compiler resolves the method call " e.eat(noodles) [which is at line 6] with the method definition specified in line 8 that is it method which takes noodles as parameter and the entire process is done by Compiler so it is Compile time Polymorphism. The process of replacement of the method call with method definition is called as binding, in this case, it is done by the compiler so it is called as early binding.

As the alert method in JavaScript does not return a Boolean or yield the current thread, you must use a different method.

My number one recommendation requires a little CSS experience. You should instead create a div element that is fixed positionally.

Otherwise you could use the confirm() method.

confirm("Successful Message");
window.location.reload();

However, this will add a cancel button. Because the confirm method is not within an if statement though, the cancel button will still refresh the page like you want it.

Update

data.table v1.9.6+ now supports OP's original attempt and the following answer is no longer necessary.

You can use DT[order(-rank(x), y)].

   x y v
1: c 1 7
2: c 3 8
3: c 6 9
4: b 1 1
5: b 3 2
6: b 6 3
7: a 1 4
8: a 3 5
9: a 6 6

Another option is to ensure that the full qualified host name (FQDN) is listed in /etc/hosts. This worked for me on Ubuntu v11.10 without having to change the default Apache configuration.

Lets say to want to make default version as 10.19.0.

nvm alias default v10.19.0

But it will give following error

! WARNING: Version 'v10.19.0' does not exist.
default -> v10.19.0 (-> N/A)

In That case you need to run two commands in the following order

# Install the version that you would like 
nvm install 10.19.0

# Set 10.19.0 (or another version) as default
nvm alias default 10.19.0

I have an answer for you Yes, It is possible.

Go to

SQL Server Management Studio > select Database > click on attach

Then select and add .mdf and .ldf file. Click on OK.

It's somewhat cleaner as the other solutions because it doesn't use any hacks nor depends on Browser JS functions, e.g. works also in other JS environments.

You can also use a second image to give the effect of a button being pressed. Just add the "pressed" button image in the HTML before the input image:

<img src="http://integritycontractingofva.com/images/go2.jpg" id="pressed"/>
<input id="unpressed" type="submit" value=" " style="background:url(http://integritycontractingofva.com/images/go1.jpg) no-repeat;border:none;"/>

And use CSS to change the opacity of the "unpressed" image on hover:

#pressed, #unpressed{position:absolute; left:0px;}
#unpressed{opacity: 1; cursor: pointer;}
#unpressed:hover{opacity: 0;}

I use it for the blue "GO" button on this page

Because of double print function. I suggest you to use return instead of print inside the function definition.

def lyrics():
    return "The very first line"
print(lyrics())

OR

def lyrics():
    print("The very first line")
lyrics()

You need text() or html() for label not val() The function should not be called for label instead it is used to get values of input like text or checkbox etc.

Change

value = $("#telefon").val(); 

To

value = $("#telefon").text(); 

via https://speakerdeck.com/anguscroll/es6-uncensored by Angus Croll

It turns out, we can use spread operator:

var myArr = [...mySet];

Or, alternatively, use Array.from:

var myArr = Array.from(mySet);

This solution worked for me:

<body onload="setTimeout(function() { document.myform.submit() }, 5000)">
   <form action=TripRecorder name="myform">
      <textarea id="result1"  name="res1" value="str1" cols="20" rows="1" ></textarea> <br> <br/>
      <textarea id="result2" name="res2" value="str2" cols="20" rows="1" ></textarea>
   </form>
</body>

^(\(?[0-9]{3}\)?)((\s|\-){1})?[0-9]{3}((\s|\-){1})?[0-9]{4}$

Assuming you are validating US phone numbers, this will do the trick.

First, we allow 0 or 1 open parentheses to start \(?

Then, we allow 3 consecutive digits between 0-9 [0-9]{3}

After, we repeat the first step and allow 0 or 1 closing parentheses \)?

For the second grouping, we start by allowing a space or a hyphen 0 or 1 times ((\s|\-){1})?

This is repeated between the second and third grouping of numbers, and we check for 3 consecutive digits then four consecutive digits to end it. For US phone numbers I think this covers the bases for a lot of different ways that people might format the number, but is restrictive enough that they can't pass an unreasonable string.

Most answers here will work fine if you have just two conditions in your if-else. For more which is I guess what you want, you'll be using arrays. Every names corresponding element in names array you'll have an element in the hasNames array with the exact same index. Then it's a matter of these four lines.

names = "true";
var names = ["true","false","1","2"];
var hasNames = ["Y","N","true","false"];
var intIndex = names.indexOf(name);
hasName = hasNames[intIndex ];

This method could also be implemented using Objects and properties as illustrated by Benjamin.

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

You may use the String.split() method:

String[] tokens = str.split(",");

After that, use Double.parseDouble() method to parse the string value to a double.

double latitude = Double.parseDouble(tokens[0]);
double longitude = Double.parseDouble(tokens[1]);

Similar parse methods exist in the other wrapper classes as well - Integer, Boolean, etc.

You can use just JavaScript:

window.location = 'http://address.com';

Add script with query parameters

That was my case. It actually links to question #4485874, but I'm going to explain it here shortly.
When you try to require path/to/script.php?parameter=value, PHP looks for file named script.php?parameter=value, because UNIX allows you to have paths like this.
If you are really need to pass some data to included script, just declare it as $variable=... or $GLOBALS[]=... or other way you like.

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

Yes my dear friends said correctly. Layer is a logical partition of application whereas tier is physical partition of system tier partition is depends on layer partition. Just like an application execute on single machine but it follows 3 layered architecture, so we can say that layer architecture could be exist in a tier architecture. In simple term 3 layer architecture can implement in single machine then we can say that its is 1 tier architecture. If we implement each layer on separate machine then its called 3 tier architecture. A layer may also able to run several tier. In layer architecture related component to communicate to each other easily.
Just like we follow given below architecture

1. presentation layer
2. business logic layer
3. data access layer

A client could interact to "presentation layer", but they access public component of below layer's (like business logic layer's public component) to "business logic layer" due to security reason.
Q * why we use layer architecture ? because if we implement layer architecture then we increase our applications efficiency like

==>security

==>manageability

==>scalability

other need like after developing application we need to change dbms or modify business logic etc. then it is necessary to all.

Q * why we use tier architecture?

because physically implementation of each layer gives a better efficiency ,without layer architecture we can not implement tier architecture. separate machine to implement separate tier and separate tier is implement one or more layer that's why we use it.
it uses for the purposes of fault tolerance. ==>easy to maintain.

Simple example

Just like a bank open in a chamber, in which categories the employee:

1. gate keeper
2. a person for cash
3. a person who is responsible to introduce banking scheme
4. manager

they all are the related components of system.

If we going to bank for loan purpose then first a gate keeper open the door with smile after that we goes to near a person that introduce to all scheme of loan after that we goes to manager cabin and pass the loan. After that finally we goes to cashier's counter take loan. These are layer architecture of bank.

What about tier? A bank's branch open in a town, after that in another town, after that in another but what is the basic requirement of each branch

1. gate keeper
2. a person for cash
3. a person who is responsible to introduce banking scheme
4. manager

exactly the same concept of layer and tier.

use the following

It will return a true or false

I used below ms sql script pattern several times successfully which uses Try-Catch,Commit Transaction- Rollback Transaction,Error Tracking.

Your TRY block will be as follows

 BEGIN TRY
 BEGIN TRANSACTION T
 ----
 //your script block
 ----
 COMMIT TRANSACTION T 
 END TRY

Your CATCH block will be as follows

BEGIN CATCH
DECLARE @ErrMsg NVarChar(4000), 
        @ErrNum Int, 
        @ErrSeverity Int, 
        @ErrState Int, 
        @ErrLine Int, 
        @ErrProc NVarChar(200)
 SELECT @ErrNum = Error_Number(), 
       @ErrSeverity = Error_Severity(), 
       @ErrState = Error_State(), 
       @ErrLine = Error_Line(), 
       @ErrProc = IsNull(Error_Procedure(), '-')
 SET @ErrMsg = N'ErrLine: ' + rtrim(@ErrLine) + ', proc: ' + RTRIM(@ErrProc) + ', 
       Message: '+ Error_Message()

Your ROLLBACK script will be part of CATCH block as follows

IF (@@TRANCOUNT) > 0 
BEGIN
PRINT 'ROLLBACK: ' + SUBSTRING(@ErrMsg,1,4000)
ROLLBACK TRANSACTION T
END
ELSE
BEGIN
PRINT SUBSTRING(@ErrMsg,1,4000);   
END

END CATCH

Above different script blocks you need to use as one block. If any error happens in the TRY block it will go the the CATCH block. There it is setting various details about the error number,error severity,error line ..etc. At last all these details will get append to @ErrMsg parameter. Then it will check for the count of transaction (@@TRANCOUNT >0) , ie if anything is there in the transaction for rollback. If it is there then show the error message and ROLLBACK TRANSACTION. Otherwise simply print the error message.

We have kept our COMMIT TRANSACTION T script towards the last line of TRY block in order to make sure that it should commit the transaction(final change in the database) only after all the code in the TRY block has run successfully.

This applies for "Intellij Idea- 2020.1.2" on window

Navigate to "IntelliJ IDEA->File->Settings->Editor->Code Style->java".

When using laravel framework, I had some issues with using a route->back() function since it erased my hash. In order to keep my hash, I created a simple function:

$(function() {   
    if (localStorage.getItem("hash")    ){
     location.hash = localStorage.getItem("hash");
    }
}); 

and I set it in my other JS function like this:

localStorage.setItem("hash", myvalue);

You can name your local storage values any way you like; mine named hash.

Therefore, if the hash is set on PAGE1 and then you navigate to PAGE2; the hash will be recreated on PAGE1 when you click Back on PAGE2.

There is maybe a bit of a gotcha in the phrasing of the original question:

I need to check that two conditions are both true before enabling a button

The first thing to remember that the ng-disabled directive is evaluating a condition under which the button should be, well, disabled, but the original question is referring to the conditions under which it should en enabled. It will be enabled under any circumstances where the ng-disabled expression is not "truthy".

So, the first consideration is how to rephrase the logic of the question to be closer to the logical requirements of ng-disabled. The logical inverse of checking that two conditions are true in order to enable a button is that if either condition is false then the button should be disabled.

Thus, in the case of the original question, the pseudo-expression for ng-disabled is "disable the button if condition1 is false or condition2 is false". Translating into the Javascript-like code snippet required by Angular (https://docs.angularjs.org/guide/expression), we get:

!condition1 || !condition2

Zoomlar has it right!

• the Id selector is used when referring to a single unique element.
• The Class selector referrers a group of elements.

For example, if you have a multiple buttons that look the same, you should use class="mybutton" to have consistent styling.

In terms of performance:

CSS selectors are matched from right to left.

Therefore, .myClass should be "faster" than #myID because it misses out testing.

The performance speed is negligible for normally sized pages and you will probably never notice a difference so it's mostly just about convention.

Here is more info on why css is browsers match css selectors from right to left

Like this.

function printMousePos(event) {_x000D_
  document.body.textContent =_x000D_
    "clientX: " + event.clientX +_x000D_
    " - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);

MouseEvent - MDN

MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.

MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.

PHP mail function can send email in 2 scenarios:

a. Try to send email via unix sendmail program At linux it will exec program "sendmail", put all params to sendmail and that all.

OR

b. Connect to mail server (using smtp protocol and host/port/username/pass from php.ini) and try to send email.

If php unable to connect to email server it will give warning (and you see such workning in your logs) To solve it, install smtp server on your local machine or use any available server. How to setup / configure smtp you can find on php.net

If you want this in order to be able to return the List in a getter it would be better to do:

ImmutableList.copyOf(list);

Also, be aware of differences in casting, especially when working with bitmasks, due to casting to signed char:

bool a = 0x0100;
a == true;  // expression true

BOOL b = 0x0100;
b == false; // expression true on !((TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH), e.g. MacOS
b == true;  // expression true on (TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH

If BOOL is a signed char instead of a bool, the cast of 0x0100 to BOOL simply drops the set bit, and the resulting value is 0.

Whilst the listed answer is correct, may I suggest that if your column is to hold case sensitive strings you read the documentation and alter your table definition accordingly.

In my case this amounted to defining my column as:

`tag` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ''

This is in my opinion preferential to adjusting your queries.

In WPF there are certain 'container' controls that automatically resize their contents and there are some that don't.

Here are some that do not resize their contents (I'm guessing that you are using one or more of these):

StackPanel
WrapPanel
Canvas
TabControl

Here are some that do resize their contents:

Grid
UniformGrid
DockPanel

Therefore, it is almost always preferable to use a Grid instead of a StackPanel unless you do not want automatic resizing to occur. Please note that it is still possible for a Grid to not size its inner controls... it all depends on your Grid.RowDefinition and Grid.ColumnDefinition settings:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="100" /> <!--<<< Exact Height... won't resize -->
        <RowDefinition Height="Auto" /> <!--<<< Will resize to the size of contents -->
        <RowDefinition Height="*" /> <!--<<< Will resize taking all remaining space -->
    </Grid.RowDefinitions>
</Grid>

You can find out more about the Grid control from the Grid Class page on MSDN. You can also find out more about these container controls from the WPF Container Controls Overview page on MSDN.

Further resizing can be achieved using the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties. The default value of these properties is Stretch which will stretch elements to fit the size of their containing controls. However, when they are set to any other value, the elements will not stretch.

UPDATE >>>

In response to the questions in your comment:

Use the Grid.RowDefinition and Grid.ColumnDefinition settings to organise a basic structure first... it is common to add Grid controls into the cells of outer Grid controls if need be. You can also use the Grid.ColumnSpan and Grid.RowSpan properties to enable controls to span multiple columns and/or rows of a Grid.

It is most common to have at least one row/column with a Height/Width of "*" which will fill all remaining space, but you can have two or more with this setting, in which case the remaining space will be split between the two (or more) rows/columns. 'Auto' is a good setting to use for the rows/columns that are not set to '"*"', but it really depends on how you want the layout to be.

There is no Auto setting that you can use on the controls in the cells, but this is just as well, because we want the Grid to size the controls for us... therefore, we don't want to set the Height or Width of these controls at all.

The point that I made about the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties was just to let you know of their existence... as their default value is already Stretch, you don't generally need to set them explicitly.

The Margin property is generally just used to space your controls out evenly... if you drag and drop controls from the Visual Studio Toolbox, VS will set the Margin property to place your control exactly where you dropped it but generally, this is not what we want as it will mess with the auto sizing of controls. If you do this, then just delete or edit the Margin property to suit your needs.

After looking at the code you're having typos, here is the updated code

var clicks = 0; // should be var not int
    function clickME() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks; //getElementById() not getElementByID() Which you corrected in edit
 }

Demo

Note: Don't use in-built handlers, as .click() is javascript function try giving different name like clickME()

1) Download new PHP from the official site (better some zip). Old php directory rename to php_old and create again php directory and put there unzipped files.

In php.ini connect needed modules if you used something that was turned off by default (like Memcached etc.), but doesn't forget to add corresponding .dll files.

2) In my case, I had to update Apache. So repeat the same steps: download the new package, rename directories, create new apache directory and put their new files.

Now you can try to restart apache running apache_start.bat from xampp folder (better run this bat, than restart apache service from Windows services window, cause in this case in console you'll see all errors if there will be some, including lines in config where you'll have problem). If you updated Apache and run this file, in the list of services you'll see Apache2.2, but in description you can get another version (in my case that was Apache/2.4.7).

In case of Apache update you can get some problems, so mind:

• after you replace the whole directory, you may need to configure you apache/conf/httpd.conf file (copy virtual hosts from old config, set up DocumentRoots, permissions for directories, all paths, extend the list of index files (by default apache has only index.html so other index files will be just ignored and Apache will just list the site root directory in browser), configure you logs etc.)

• connect modules you need (if you used something that was not turned on by default like mod_rewrite etc.)

I had some issues playing on Android Phone. After few tries I found out that when Data Saver is on there is no auto play:

There is no autoplay if Data Saver mode is enabled. If Data Saver mode is enabled, autoplay is disabled in Media settings.

If you have access to the remote repo from a shell, just go into the .git (or the main dir if its a bare repo) and change the HEAD file to point to the correct head. For example, by default it always contains 'refs: refs/heads/master', but if you need foo to be the HEAD instead, just edit the HEAD file and change the contents to 'refs: refs/heads/foo'.

Had the same issue; validated HTML & found I was missing a name="email" attribute from an <input />. Always validate the HTML to be positive your HTML is valid. After I added it, validate() worked perfectly.

Well its very simple in controller you have somthing like this:

-- Controller

ViewBag.Profile_Id = new SelectList(db.Profiles, "Id", "Name", model.Profile_Id);

--View (Option A)

@Html.DropDownList("Profile_Id")

--View (Option B) --> Send a null value to the list

@Html.DropDownList("Profile_Id", null, "-- Choose --", new {  @class = "input-large" })

SELECT  (
    SELECT COUNT(*)
    FROM   user_table
) AS tot_user,
(
    SELECT COUNT(*)
    FROM   cat_table
) AS tot_cat,
(
    SELECT COUNT(*)
    FROM   course_table
) AS tot_course

I have one more solution. If anybody uses AngularJs : http://jsfiddle.net/ec9gn/30/

<div ng-controller='ctrl'>
    <img ng-mouseover="img='eb00eb'"  ng-mouseleave="img='000'"
         ng-src='http://dummyimage.com/100x100/{{img}}/fff' />
</div>

The Javascript :

function ctrl($scope){
    $scope.img= '000';
}

No CSS ^^.

This works fine for Laravel 5.6

<?php echo "$text"; ?>

In a different way

{!! $text !!}

It will not render HTML code and print as a string.

For more details open link:- Display HTML with Blade

I was working with a class that did not contain a reference to the context. So it was not possible for me to use runOnUIThread(); I used view.post(); and it was solved.

timer.scheduleAtFixedRate(new TimerTask() {

    @Override
    public void run() {
        final int currentPosition = mediaPlayer.getCurrentPosition();
        audioMessage.seekBar.setProgress(currentPosition / 1000);
        audioMessage.tvPlayDuration.post(new Runnable() {
            @Override
            public void run() {
                audioMessage.tvPlayDuration.setText(ChatDateTimeFormatter.getDuration(currentPosition));
            }
        });
    }
}, 0, 1000);

This seems homework-y, so I'll give a hint rather than a detailed explanation. Correct me if I've assumed wrong.

You're doing fine as far as bailing out when you see an even divisor.

But you're printing 'count' as soon as you see even one number that doesn't divide into it. 2, for instance, does not divide evenly into 9. But that doesn't make 9 a prime. You might want to keep going until you're sure no number in the range matches.

(as others have replied, a Sieve is a much more efficient way to go... just trying to help you understand why this specific code isn't doing what you want)

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

Standard xargs has no good way to do it; you're better off using find -exec as someone else suggested, or wrap the sed in a script which does nothing if there are no arguments. GNU xargs has the --no-run-if-empty option, and BSD / OS X xargs has the -L option which looks like it should do something similar.

For me when I created a file and saved it as python file, I was getting this error during importing. I had to create a filename with the type ".py" , like filename.py and then save it as a python file. post trying to import the file worked for me.

Swift 3 : Array() can be useful to do this .

Get Key :

let index = 5 // Int Value
Array(myDict)[index].key

Get Value :

Array(myDict)[index].value

>>> dic0 = {'dic0':0}
>>> dic1 = {'dic1':1}
>>> ndic = dict(dic0.items() + dic1.items())
>>> ndic
{'dic0': 0, 'dic1': 1}

Agile is a platform and scrum is a methodology to follow. Scrum recommends certain practices to be followed. Some of the basic scrum practices are following.

• Fixed length Scrum/Releases.
• Suggested meeting Structures (Release planning meeting, Sprint planning meeting, Sprint Review and Sprint Retrospective meetings)

• Scrum also recommends roles. Following are the roles recommended by Scrum.

   - Scrum Master
   - Developer Team
   - Product Owner
  

The Scrum, just like other Agile methodologies follow iterative approach.

Following are some other Agile methodologies.

• Extreme Programming.
• Agile unified process
• Dynamic System Development Method (DSDM)
• Feature Driven Development (FDD)
• Lean Software Development
• Kanban
• Scrum-ban

There are many scrum tool in the market. Yodiz is one of them that we use.

You've correctly diagnosed your problem, so good job. Once you call into your search code, the for loop just keeps right on going.

I'm a big fan of https://github.com/caolan/async, and it serves me well. Basically with it you'd end up with something like:

var async = require('async')
async.eachSeries(Object.keys(config), function (key, next){ 
  search(config[key].query, function(err, result) { // <----- I added an err here
    if (err) return next(err)  // <---- don't keep going if there was an error

    var json = JSON.stringify({
      "result": result
    });
    results[key] = {
      "result": result

  })
}, function(err) {
  console.log('iterating done');
}); 

I hope that helps!

I would recommend separating out all of the foreign-key constraints from your CREATE TABLE statements. Create all the tables first without FK constraints, and then create all the FK constraints once you have created the tables.

You can add an FK constraint to a table using SQL like the following:

ALTER TABLE orders ADD CONSTRAINT orders_FK
  FOREIGN KEY (m_p_unique_id) REFERENCES library (m_p_unique_id);

In particular, your formats and library tables both have foreign-key constraints on one another. The two CREATE TABLE statements to create these two tables can never run successfully, as each will only work when the other table has already been created.

Separating out the constraint creation allows you to create tables with FK constraints on one another. Also, if you have an error with a constraint, only that constraint fails to be created. At present, because you have errors in the constraints in your CREATE TABLE statements, then entire table creation fails and you get various knock-on errors because FK constraints may depend on these tables that failed to create.

This is very late, but I was wondering why energee's solution works: specifically, how the <object> element affects its parent elements.

tl;dr You cannot click on an anchor that has an <object> element in it because the click events are being captured by whatever is inside of the <object> element, which then doesn't bubble it back out.

jsfiddle

To expand on the symptom described in the original question: not only will an <object> element inside an anchor element cause the anchor to become unclickable, it seems that an <object> element as a child of any element will cause click, mousedown, and mouseup events (possibly touch events too) to not fire on the parent element, (when you are clicking inside the <object>'s bounding rect.)

<span>
    <object type="image/svg+xml" data="https://icons.getbootstrap.com/icons/three-dots.svg">
    </object>
</span>

document
    .querySelector('span')
    .addEventListener('click', console.log) // will not fire

Now, <object> elements behave somewhat "like" <iframe>s, in the sense that they will establish new browsing contexts, including when the content is an <svg> document. In JavaScript, this is manifested through the existence of the HTMLObjectElement.contentDocument and HTMLObjectElement.contentWindow properties.

This means that if you add an event listener to the <svg> element inside the <object>:

document
    .querySelector('object')
    .contentDocument  // returns null if cross-origin: the same-origin policy
    .querySelector('svg')
    .addEventListener('click', console.log)

and then click on the image, you will see the events being fired.

Then it becomes clear why the pointer-events: none; solution works:

• Without this style, any MouseEvent that is considered "interactive" (such as click and mousedown, but not mouseenter) is sent to the nested browsing context inside the <object>, which will never bubble out of it.

• With this style, the MouseEvents aren't sent into the <object> in the first place, then the <object>'s parent elements will receive the events as usual.

This should explain the z-index solution as well: as long as you can prevent click events from being sent to the nested document, the clicking should work as expected.

(In my test, the z-index solution will work as long as the parent element is not inline and the <object> is positioned and has a negative z-index)

(Alternatively, you can find a way to bubble the event back up):

let objectElem = document.querySelector('object')
let svgElemt = objectElem.contentDocument.querySelector('svg')

svgElem.addEventListener('click', () => {
    window.postMessage('Take this click event please.')
    // window being the outermost window
})

window.addEventListener('message', console.log)

no, the difference between + and \; should be reversed. + appends the files to the end of the exec command then runs the exec command and \; runs the command for each file.

The problem is find . -type f -iname '*.cpp' -exec mv {} ./test/ \+ should be find . -type f -iname '*.cpp' -exec mv {} ./test/ + no need to escape it or terminate the +

xargs I haven't used in a long time but I think works like +.

The first response is the best solution:

Add an onsubmit handler to the form (either via plain js or jquery $().submit(fn)), and return false unless your specific conditions are met.

More specific with jquery:

$('#your-form-id').submit(function(){return false;});

Unless you don't want the form to submit, ever - in which case, why not just leave out the 'action' attribute on the form element?

Writing Chrome extensions is an example of where you might have a form for user input, but you don't want it to submit. If you use action="javascript:void(0);", the code will probably work but you will end up with this problem where you get an error about running inline Javascript.

If you leave out the action completely, the form will reload which is also undesired in some cases when writing a Chrome extension. Or if you had a webpage with some sort of an embedded calculator, where the user would provide some input and click "Calculate" or something like that.

#!/bin/bash
password='complex=!password'
PGPASSWORD=$(echo $password) psql -h example.com -U example_user -d example_db -t -c "select * from example_table1" -o example_out.txt 

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

Update: Starting with Spring Boot v1.2.0.RELEASE, the settings in application.properties or application.yml do apply. See the Log Levels section of the reference guide.

logging.level.org.springframework.web: DEBUG
logging.level.org.hibernate: ERROR

For earlier versions of Spring Boot you cannot. You simply have to use the normal configuration for your logging framework (log4j, logback) for that. Add the appropriate config file (log4j.xml or logback.xml) to the src/main/resources directory and configure to your liking.

You can enable debug logging by specifying --debug when starting the application from the command-line.

Spring Boot provides also a nice starting point for logback to configure some defaults, coloring etc. the base.xml file which you can simply include in your logback.xml file. (This is also recommended from the default logback.xml in Spring Boot.

<include resource="org/springframework/boot/logging/logback/base.xml"/>     

As a workaround to this limitation, I use two rules to cover all the cases.

For example, if I want to allow or deny these 18 ports:

465,110,995,587,143,11025,20,21,22,26,80,443,3000,10000,7080,8080,3000,5666

I use the below rules:

iptables -A INPUT -p tcp -i eth0 -m multiport --dports 465,110,995,587,143,11025,20,21,22,26,80,443 -j ACCEPT

iptables -A INPUT -p tcp -i eth0 -m multiport --dports 3000,10000,7080,8080,3000,5666 -j ACCEPT

The above rules should work for your scenario also. You can create another rule if you hit 15 ports limit on both first and second rule.

1. Change the setting from built-in account to custom account and enter the other server's username and password.

2. Keep the setting as integrated (instead of classic mode).

Try this :

<button> @Html.ActionLink(" ", "DeletePhoto", "PhotoAndVideo", new { id = item.Id }, new { @class = "modal-link1", @OnClick = "return confirm('Are you sure you to delete this Record?');" })</button>

Thanks to @Cory's hint, i used this:

inputChangeHandler : function (event) {
    var stateObject = function() {
      returnObj = {};
      returnObj[this.target.id] = this.target.value;
         return returnObj;
    }.bind(event)();

    this.setState( stateObject );    
},

If using ES6 or the Babel transpiler to transform your JSX code, you can accomplish this with computed property names, too:

inputChangeHandler : function (event) {
    this.setState({ [event.target.id]: event.target.value });
    // alternatively using template strings for strings
    // this.setState({ [`key${event.target.id}`]: event.target.value });
}

Try out below drawable file. Create file named "circle" in your res/drawable folder and copy below code:

   <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >

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

    <stroke
        android:width="1dp"
        android:color="#4a6176" />

    <padding
        android:left="10dp"
        android:right="10dp"
        android:top="10dp"
        android:bottom="10dp"
         />

    <corners android:radius="10dp" />

</shape>

Apply it in your TextView as below:

<TextView
        android:id="@+id/tvSummary1"
        android:layout_width="270dp"
        android:layout_height="60dp"
        android:text="Hello World" 
        android:gravity="left|center_vertical"
        android:background="@drawable/round_bg">

    </TextView>

Is this what you are after? Just index the element and assign a new value.

A[2,1]=150

A
Out[345]: 
array([[ 1,  2,  3,  4],
       [ 5,  6,  7,  8],
       [ 9, 150, 11, 12],
       [13, 14, 15, 16]])

resetting seems a necessity to meet custom design specifications, especially on complex, non-boilerplate type design projects. It sounds as though normalizing is a good way to proceed with purely web programming in mind, but oftentimes websites are a marriage between web programming and UI/UX design rules.

Set return type to Void instead of void and return null

// Modify existing method
public static Void displayInt(Integer i) {
    System.out.println(i);
    return null;
}

OR

// Or use Lambda
myForEach(theList, i -> {System.out.println(i);return null;});

It might be a little late to the discussion but inevitably someone will stumble onto this post like I did. I found the answer I was looking for and thought I'd post my own take on it. The following JSfiddle includes how to layer .PNG's with transparency. Jerska's mention of the transparency attribute for the div's CSS was the solution: http://jsfiddle.net/jyef3fqr/

HTML:

   <button id="toggle-box">toggle</button>
   <div id="box" style="display:none;" ><img src="x"></div>
   <button id="toggle-box2">toggle</button>
   <div id="box2" style="display:none;"><img src="xx"></div>
   <button id="toggle-box3">toggle</button>
   <div id="box3" style="display:none;" ><img src="xxx"></div>

CSS:

#box {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:1;
}
#box2 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
      }
      #box3 {
background-color: #ffffff;
height:400px;
width: 1200px;
position: absolute;
top:30px;
z-index:2;
background-color : transparent;
      }
 body {background-color:#c0c0c0; }

JS:

$('#toggle-box').click().toggle(function() {
$('#box').animate({ width: 'show' });
}, function() {
$('#box').animate({ width: 'hide' });
});

$('#toggle-box2').click().toggle(function() {
$('#box2').animate({ width: 'show' });
}, function() {
$('#box2').animate({ width: 'hide' });
});
$('#toggle-box3').click().toggle(function() {
$('#box3').animate({ width: 'show' });
 }, function() {
$('#box3').animate({ width: 'hide' });
});

And my original inspiration:http://jsfiddle.net/5g1zwLe3/ I also used paint.net for creating the transparent PNG's, or rather the PNG's with transparent BG's.

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

You did syntax declaration error, use proper setTimeout declaration

message:() => { 
  setTimeout(() => {this.setState({opened:false})},3000); 
  return 'Thanks for your time, have a nice day ! 
}

There are two ways to accomplish this,

1. LINQ to XML
2. XPath

The following are samples of using these approaches,

List<XElement> result = doc.Root.Element("emails").Elements("emailAddress").ToList();

If you use XPath, you need to do some manipulation with the IEnumerable:

IEnumerable<XElement> mails = ((IEnumerable)doc.XPathEvaluate("/emails/emailAddress")).Cast<XElement>();

Note that

var res = doc.XPathEvaluate("/emails/emailAddress");

results either a null pointer, or no results.

Use the following:

SELECT * FROM `calendar` WHERE DATE(startTime) = '2010-04-29'

Just for reference I have a 2 million record table, I ran a similar query. Salils answer took 4.48 seconds, the above took 2.25 seconds.

So if the table is BIG I would suggest this rather.

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

After some investigation and general hair-pulling the solution seems to be HTML2PDF. DOMPDF did a terrible job with tables, borders and even moderately complex layout and htmldoc seems reasonably robust but is almost completely CSS-ignorant and I don't want to go back to doing HTML layout without CSS just for that program.

HTML2PDF looked the most promising but I kept having this weird error about null reference arguments to node_type. I finally found the solution to this. Basically, PHP 5.1.x worked fine with regex replaces (preg_replace_*) on strings of any size. PHP 5.2.1 introduced a php.ini config directive called pcre.backtrack_limit. What this config parameter does is limits the string length for which matching is done. Why this was introduced I don't know. The default value was chosen as 100,000. Why such a low value? Again, no idea.

A bug was raised against PHP 5.2.1 for this, which is still open almost two years later.

What's horrifying about this is that when the limit is exceeded, the replace just silently fails. At least if an error had been raised and logged you'd have some indication of what happened, why and what to change to fix it. But no.

So I have a 70k HTML file to turn into PDF. It requires the following php.ini settings:

• pcre.backtrack_limit = 2000000; # probably more than I need but that's OK
• memory_limit = 1024M; # yes, one gigabyte; and
• max_execution_time = 600; # yes, 10 minutes.

Now the astute reader may have noticed that my HTML file is smaller than 100k. The only reason I can guess as to why I hit this problem is that html2pdf does a conversion into xhtml as part of the process. Perhaps that took me over (although nearly 50% bloat seems odd). Whatever the case, the above worked.

Now, html2pdf is a resource hog. My 70k file takes approximately 5 minutes and at least 500-600M of RAM to create a 35 page PDF file. Not quick enough (by far) for a real-time download unfortunately and the memory usage puts the memory usage ratio in the order of 1000-to-1 (600M of RAM for a 70k file), which is utterly ridiculous.

Unfortunately, that's the best I've come up with.

This is the implementation of endsWith:

String.prototype.endsWith = function (str) {
  return (this.length >= str.length) && (this.substr(this.length - str.length) === str);
}

Go to

https://github.com/Darkseal/bootstrap4-glyphicons

download and include in your code

<link href="bootstrap4-glyphicons/css/bootstrap-glyphicons.css" rel="stylesheet">

Value of string::npos is 18446744073709551615. Its a value returned if there is no string found.

You'll need to save as a blob, LONGBLOB datatype in mysql will work.

Ex:

CREATE TABLE 'test'.'pic' (
    'idpic' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
    'caption' VARCHAR(45) NOT NULL,
    'img' LONGBLOB NOT NULL,
  PRIMARY KEY ('idpic')
)

As others have said, its a bad practice but it can be done. Not sure if this code would scale well, though.

Try this:

alert($('#radiobutton')[0].checked)

singletonList can hold instance of any object. Object state can be modify.

List<Character> list = new ArrayList<Character>();
list.add('X');
list.add('Y');
System.out.println("Initial list: "+ list);
List<List<Character>> list2 = Collections.singletonList(list);
list.add('Z');
System.out.println(list);
System.out.println(list2);

We can not define unmodifiableList like above.

Late, but to show an easy solution using promises after their introduction in ES6, it handles asynchronous calls a lot easier:

You set the asynchronous code in a new promise:

var asyncFunct = new Promise(function(resolve, reject) {
    $('#link').animate({ width: 200 }, 2000, function() {
        console.log("finished");                
        resolve();
    });             
});

Note to set resolve() when async call finishes.
Then you add the code that you want to run after async call finishes inside .then() of the promise:

asyncFunct.then((result) => {
    console.log("Exit");    
});

Here is a snippet of it:

$('#link').click(function () {_x000D_
    console.log("Enter");_x000D_
    var asyncFunct = new Promise(function(resolve, reject) {_x000D_
        $('#link').animate({ width: 200 }, 2000, function() {_x000D_
            console.log("finished");             _x000D_
            resolve();_x000D_
        });    _x000D_
    });_x000D_
    asyncFunct.then((result) => {_x000D_
        console.log("Exit");    _x000D_
    });_x000D_
});

Consolodating other answers, per Joel, and hopefully improving slightly as I go:

You can do this with Regex.Replace():

string s = Regex.Replace (
    "   1  2    4 5", 
    @"[ ]{2,}", 
    " "
    );

Or with String.Split():

static class StringExtensions
{
    public static string Join(this IList<string> value, string separator)
    {
        return string.Join(separator, value.ToArray());
    }
}

//...

string s = "     1  2    4 5".Split (
    " ".ToCharArray(), 
    StringSplitOptions.RemoveEmptyEntries
    ).Join (" ");

There's a special variable for this in bash:

kill $!

$! expands to the PID of the last process executed in the background.

This works...

var string1 = "'foo'";_x000D_
var string2 = '"bar"';_x000D_
_x000D_
function removeFirstAndLastQuotes(str){_x000D_
  var firstChar = str.charAt(0);_x000D_
  var lastChar = str[str.length -1];_x000D_
  //double quotes_x000D_
  if(firstChar && lastChar === String.fromCharCode(34)){_x000D_
    str = str.slice(1, -1);_x000D_
  }_x000D_
  //single quotes_x000D_
  if(firstChar && lastChar === String.fromCharCode(39)){_x000D_
    str = str.slice(1, -1);_x000D_
  }_x000D_
  return str;_x000D_
}_x000D_
console.log(removeFirstAndLastQuotes(string1));_x000D_
console.log(removeFirstAndLastQuotes(string2));

Actually, this has nothing to do with the usual Windows / Unix \r\n vs \n issue. The TELNET procotol itself defines \r\n as the end-of-line sequence, independently of the operating system. See RFC854.

As an alternative to explicitly catching and handling the exception you could tell Oracle to catch and automatically ignore the exception by including a /*+ hint */ in the insert statement. This is a little faster than explicitly catching the exception and then articulating how it should be handled. It is also easier to setup. The downside is that you do not get any feedback from Oracle that an exception was caught.

Here is an example where we would be selecting from another table, or perhaps an inner query, and inserting the results into a table called TABLE_NAME which has a unique constraint on a column called IDX_COL_NAME.

INSERT /*+ ignore_row_on_dupkey_index(TABLE_NAME(IDX_COL_NAME)) */ 
INTO TABLE_NAME(
    INDEX_COL_NAME
  , col_1
  , col_2
  , col_3
  , ...
  , col_n)
SELECT 
    INDEX_COL_NAME
  , col_1
  , col_2
  , col_3
  , ...
  , col_n);

This is not a great solution if your goal it to catch and handle (i.e. print out or update the row that is violating the constraint). But if you just wanted to catch it and ignore the violating row then then this should do the job.

How do I print out my $ids and $nIds?

print "$ids\n";
print "$nIds\n";

I tried simply print $ids, but Perl complains.

Complains about what? Uninitialised value? Perhaps your loop was never entered due to an error opening the file. Be sure to check if open returned an error, and make sure you are using use strict; use warnings;.

my ($ids, $nIds) is a list, right? With two elements?

It's a (very special) function call. $ids,$nIds is a list with two elements.

It's probably easiest to use HttpURLConnection.

http://www.xyzws.com/Javafaq/how-to-use-httpurlconnection-post-data-to-web-server/139

You'll use JSONObject or whatever to construct your JSON, but not to handle the network; you need to serialize it and then pass it to an HttpURLConnection to POST.

It cant find the entry point for your program, in this case main(). Your linker settings are likely incorrect.

See this post here

This should get the id added.

ASP.NET MVC 5 and lower:

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "signupform" }))
   { } %>

ASP.NET Core: You can use tag helpers in forms to avoid the odd syntax for setting the id.

<form asp-controller="Account" asp-action="Register" method="post" id="signupform" role="form"></form>

There is something wrong with the accepted answer, it sometimes (randomly) brings a clipped response from server. I do not know why, I did not investigate the faulty cause of the accepted answer because this code worked perfectly for me:

import paramiko

ip='server ip'
port=22
username='username'
password='password'

cmd='some useful command' 

ssh=paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(ip,port,username,password)

stdin,stdout,stderr=ssh.exec_command(cmd)
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)

stdin,stdout,stderr=ssh.exec_command('some really useful command')
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)

Wasted a lot of time on this silly issue!

add a cd command to where your batch file resides at the first line of your batch file and see if it resolves the issue.

cd D:\wherever\yourBatch\fileIs

TIP: please use absolute paths, relative paths ideally should not be an issue, but scheduler has an difficult time understanding them.

Another way to set an option element:

var select = element(by.model('organization.parent_id'));
select.$('[value="1"]').click();

Use an array, not a string, as given as guidance in BashFAQ #50.

Using a string is extremely bad security practice: Consider the case where password (or a where clause in the query, or any other component) is user-provided; you don't want to eval a password containing $(rm -rf .)!

It's really not an 'either/or' situation. AJAX stands for Asynchronous JavaScript and XML, and JQuery is a JavaScript library that takes the pain out of writing common JavaScript routines.

It's the difference between a thing (jQuery) and a process (AJAX). To compare them would be to compare apples and oranges.

<?php
print date('M d, Y', strtotime('+7 days') );

Your code was right except you are not passing the JSON keys as strings.

It should have double or single quotes around it

{ "field1": "hello", "field2" : "hello2"}

$.ajax(
   {
      type: 'post',
      url: 'superman',
      data: { 
        "field1": "hello", // Quotes were missing
        "field2": "hello1" // Here also
      },
      success: function (response) {
        alert(response);
      },
      error: function () {
        alert("error");
      }
   }
);

And for those who are looking for when you have to concatenate a char to a String rather than a String to another String as given below.

char ch = 'a';
String otherstring = "helen";
// do this
otherstring = otherstring + "" + ch;
System.out.println(otherstring);
// output : helena

If you want to convert a single VARBINARY value into VARCHAR (STRING) you can do by declaring a variable like this:

DECLARE @var VARBINARY(MAX)
SET @var = 0x21232F297A57A5A743894A0E4A801FC3
SELECT CAST(@var AS VARCHAR(MAX))

If you are trying to select from table column then you can do like this:

SELECT CAST(myBinaryCol AS VARCHAR(MAX))
FROM myTable

TL;DR

To get the token in a single oneliner:

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | awk '/^deployment-controller-token-/{print $1}') | awk '$1=="token:"{print $2}'

This assumes that your ~/.kube/config is present and valid. And also that kubectl config get-contexts indicates that you are using the correct context (cluster and namespace) for the dashboard you are logging into.

Explanation

I derived this answer from what I learned from @silverfox's answer. That is a very informative write up. Unfortunately it falls short of telling you how to actually put the information into practice. Maybe I've been doing DevOps too long, but I think in shell. It's much more difficult for me to learn or teach in English.

Here is that oneliner with line breaks and indents for readability:

kubectl -n kube-system describe secret $(
  kubectl -n kube-system get secret | \
  awk '/^deployment-controller-token-/{print $1}'
) | \
awk '$1=="token:"{print $2}'

There are 4 distinct commands and they get called in this order:

• Line 2 - This is the first command from @silverfox's Token section.
• Line 3 - Print only the first field of the line beginning with deployment-controller-token- (which is the pod name)
• Line 1 - This is the second command from @silverfox's Token section.
• Line 5 - Print only the second field of the line whose first field is "token:"

XPath 1.0, which is what MS implements, does not have the idea of a default namespace. So try this:

XDocument xdoc = XDocument.Load(@"C:\SampleXML.xml");
XmlNamespaceManager xnm = new XmlNamespaceManager(new NameTable()); 
xnm.AddNamespace("x", "http://demo.com/2011/demo-schema");
Console.WriteLine(xdoc.XPathSelectElement("/x:Report/x:ReportInfo/x:Name", xnm) == null);

#include <QFile>
#include <QCoreApplication>
#include <QTextStream>

int main(int argc, char *argv[])
{
    // Create a new file     
    QFile file("out.txt");
    file.open(QIODevice::WriteOnly | QIODevice::Text);
    QTextStream out(&file);
    out << "This file is generated by Qt\n";

    // optional, as QFile destructor will already do it:
    file.close(); 

    //this would normally start the event loop, but is not needed for this
    //minimal example:
    //return app.exec();

    return 0;
}

1) for example HTML code:

<ul>
    <li>
        <a href="#">firstlink</a>
        <span><a href="#">second link&lt;/a>
    </li>
</ul>

and css rules:

1) ul li a {color:red;} 
2) ul > li > a {color:blue;}

">" - symbol mean that that will be searching only child selector (parentTag > childTag)

so first css rule will apply to all links (first and second) and second rule will apply anly to first link

2) As for efficiency - I think second will be more fast - as in case with JavaScript selectors. This rule read from right to left, this mean that when rule will parse by browser, it get all links on page: - in first case it will find all parent elements for each link on page and filter all links where exist parent tags "ul" and "li" - in second case it will check only parent node of link if it is "li" tag then -> check if parent tag of "li" is "ul"

some thing like this. Hope I describe all properly for you

MySQL function example:

Open the mysql terminal:

el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>

Drop the function if it already exists

mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Create the function

mysql> create function hello(id INT)
    -> returns CHAR(50)
    -> return 'foobar';
Query OK, 0 rows affected (0.01 sec)

Create a simple table to test it out with

mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)

Insert three values into the table yar

mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3  Duplicates: 0  Warnings: 0

Select all the values from yar, run our function hello each time:

mysql> select id, hello(5) from yar;
+------+----------+
| id   | hello(5) |
+------+----------+
|    5 | foobar   |
|    7 | foobar   |
|    9 | foobar   |
+------+----------+
3 rows in set (0.01 sec)

Verbalize and internalize what just happened:

You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50) containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5) for each row returned by yar.

@Ahamed has a point, but if you're insisting on using lists so you can have three arraylist like this:

ArrayList<Integer> first = new ArrayList<Integer>(Arrays.AsList(100,100,100,100,100));
ArrayList<Integer> second = new ArrayList<Integer>(Arrays.AsList(50,35,25,45,65));
ArrayList<Integer> third = new ArrayList<Integer>();

for(int i = 0; i < first.size(); i++) {
      third.add(first.get(i));
      third.add(second.get(i));
}

Edit: If you have those values on your list that below:

List<double[]> values = new ArrayList<double[]>(2);

what you want to do is combine them, right? You can try something like this: (I assume that both array are same sized, otherwise you need to use two for statement)

ArrayList<Double> yourArray = new ArrayList<Double>();
for(int i = 0; i < values.get(0).length; i++) {
    yourArray.add(values.get(0)[i]);
    yourArray.add(values.get(1)[i]);
}

If you're comfortable with numba it allows to create a fast short-circuit (stops as soon as a NaN is found) function:

import numba as nb
import math

@nb.njit
def anynan(array):
    array = array.ravel()
    for i in range(array.size):
        if math.isnan(array[i]):
            return True
    return False

If there is no NaN the function might actually be slower than np.min, I think that's because np.min uses multiprocessing for large arrays:

import numpy as np
array = np.random.random(2000000)

%timeit anynan(array)          # 100 loops, best of 3: 2.21 ms per loop
%timeit np.isnan(array.sum())  # 100 loops, best of 3: 4.45 ms per loop
%timeit np.isnan(array.min())  # 1000 loops, best of 3: 1.64 ms per loop

But in case there is a NaN in the array, especially if it's position is at low indices, then it's much faster:

array = np.random.random(2000000)
array[100] = np.nan

%timeit anynan(array)          # 1000000 loops, best of 3: 1.93 µs per loop
%timeit np.isnan(array.sum())  # 100 loops, best of 3: 4.57 ms per loop
%timeit np.isnan(array.min())  # 1000 loops, best of 3: 1.65 ms per loop

Similar results may be achieved with Cython or a C extension, these are a bit more complicated (or easily avaiable as bottleneck.anynan) but ultimatly do the same as my anynan function.

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

Just adding and formalizing @David 's solution from above:

Note that jQuery functions are chainable and return 'this' so that multiple invocations can be called one after the other (e.g $container.css("overflow", "hidden").css("outline", 0);).

So the improved code should be:

(function() {
    var ev = new $.Event('style'),
        orig = $.fn.css;
    $.fn.css = function() {
        var ret = orig.apply(this, arguments);
        $(this).trigger(ev);
        return ret; // must include this
    }
})();

The documentation is misleading.
I have the following code running in production

DECLARE @table TABLE (UserID varchar(100))
DECLARE @sql varchar(1000)
SET @sql = 'spSelUserIDList'
/* Will also work
   SET @sql = 'SELECT UserID FROM UserTable'
*/

INSERT INTO @table
EXEC(@sql)

SELECT * FROM @table

Introduction

The remote server has sent you a RST packet, which indicates an immediate dropping of the connection, rather than the usual handshake.

Possible Causes

A. TCP/IP

It might be TCP/IP issue you need to resolve with your host or upgrade your OS most times connection is close before remote server before it finished downloading the content resulting to Connection reset by peer.....

B. Kannel Bug

Note that there are some issues with TCP window scaling on some Linux kernels after v2.6.17. See the following bug reports for more information:

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.17/+bug/59331

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/89160

C. PHP & CURL Bug

You are using PHP/5.3.3 which has some serious bugs too ... i would advice you work with a more recent version of PHP and CURL

https://bugs.php.net/bug.php?id=52828

https://bugs.php.net/bug.php?id=52827

https://bugs.php.net/bug.php?id=52202

https://bugs.php.net/bug.php?id=50410

D. Maximum Transmission Unit

One common cause of this error is that the MTU (Maximum Transmission Unit) size of packets travelling over your network connection have been changed from the default of 1500 bytes. If you have configured VPN this most likely must changed during configuration

D. Firewall : iptables

If you don't know your way around this guys they would cause some serious issues .. try and access the server you are connecting to check the following

• You have access to port 80 on that server

Example

 -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT`

• The Following is at the last line not before any other ACCEPT

Example

  -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited 

• Check for ALL DROP , REJECT and make sure they are not blocking your connection

• Temporary allow all connection as see if it foes through

Experiment

Try a different server or remote server ( So many fee cloud hosting online) and test the same script .. if it works then i guesses are as good as true ... You need to update your system

Others Code Related

A. SSL

If Yii::app()->params['pdfUrl'] is a url with https not including proper SSL setting can also cause this error in old version of curl

Resolution : Make sure OpenSSL is installed and enabled then add this to your code

curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST, false);

I hope it helps

Sorry for necro. I have too run into the same issue and found out that rJava expects JAVA_HOME to point to JRE. If you have JDK installed, most probably your JAVA_HOME points to JDK. My quick solution:

Sys.setenv(JAVA_HOME=paste(Sys.getenv("JAVA_HOME"), "jre", sep="\\"))

I was wondering why I was getting that big warning message on Ubuntu 16.04 (which comes with Git 2.7.4), but not on Arch Linux. The reason is that the warning was removed in Git 2.8 (March 2016):

Across the transition at around Git version 2.0, the user used to get a pretty loud warning when running "git push" without setting push.default configuration variable. We no longer warn because the transition was completed a long time ago.

So you won't see the warning if you have Git 2.8 and later and don't need to set push.default unless you want to change the default 'simple' behavior.

Plug in your device and run adb shell which will get you a command shell on your device. You don't have permission to read /storage/emulated/ but since you know it's in subdirectory 0 just go cd /storage/emulated/0 and you will be able to look around and interact as aspected.

Note: you can use adb wirelessly as well

Warning: this is not safe if executed from multiple sessions at the same time (see caveats below).

Another clever way to do an "UPSERT" in postgresql is to do two sequential UPDATE/INSERT statements that are each designed to succeed or have no effect.

UPDATE table SET field='C', field2='Z' WHERE id=3;
INSERT INTO table (id, field, field2)
       SELECT 3, 'C', 'Z'
       WHERE NOT EXISTS (SELECT 1 FROM table WHERE id=3);

The UPDATE will succeed if a row with "id=3" already exists, otherwise it has no effect.

The INSERT will succeed only if row with "id=3" does not already exist.

You can combine these two into a single string and run them both with a single SQL statement execute from your application. Running them together in a single transaction is highly recommended.

This works very well when run in isolation or on a locked table, but is subject to race conditions that mean it might still fail with duplicate key error if a row is inserted concurrently, or might terminate with no row inserted when a row is deleted concurrently. A SERIALIZABLE transaction on PostgreSQL 9.1 or higher will handle it reliably at the cost of a very high serialization failure rate, meaning you'll have to retry a lot. See why is upsert so complicated, which discusses this case in more detail.

This approach is also subject to lost updates in read committed isolation unless the application checks the affected row counts and verifies that either the insert or the update affected a row.

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

I got this error, hope this will help someone:

const firstName = 'Joe';
const lastName = 'Blogs';
const wholeName = firstName + ' ' lastName + '.';

The problem was that I was missing a plus (+) between the empty space and lastName. This is a super simplified example: I was concatenating about 9 different parts so it was hard to spot the error.

Summa summarum: if you get "SyntaxError: missing ; before statement", don't look at what is wrong with the the semicolon (;) symbols in your code, look for an error in syntax on that line.

This should work:
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Try to update your compiler, I'm using GCC 4.7 on Windows 7 Starter x86 with MinGW and it compiles fine with the same options both in C99 and C11.

Another alternative could be using:

divID = "question-" + (i - -1);

Subtracting a negative is the same as adding, and a minus cannot be used for concatenation

Edit: Forgot that brackets are still necessary since code is read from left to right.

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

I found the pipe operator did not work for me when using option 3 to concat several MP4s on a Mac in the accepted answer.

The following one-liner works on a Mac (High Sierra) to concatenate mp4s, with no intermediary file creation required.

ffmpeg -f concat -safe 0 -i <(for f in ./*.mp4; do echo "file '$PWD/$f'"; done) -c copy output.mp4

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

Michael Richardson's solution is great. If you would like to subtract dates (because Google will point you here if you search for it), you could also say:

var date1 = moment( "2014-06-07 00:03:00" );
var date2 = moment( "2014-06-07 09:22:00" );

differenceInMs = date2.diff(date1); // diff yields milliseconds
duration = moment.duration(differenceInMs); // moment.duration accepts ms
differenceInMinutes = duration.asMinutes(); // if you would like to have the output 559

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

var from = document.referrer;
console.log(from);

document.referrer won't be always available.

We have used the combination of:

1. Cobian Backup for scheduling/maintenance

2. ExpressMaint for backup

Both of these are free. The process is to script ExpressMaint to take a backup as a Cobian "before Backup" event. I usually let this overwrite the previous backup file. Cobian then takes a zip/7zip out of this and archives these to the backup folder. In Cobian you can specify the number of full copies to keep, make multiple backup cycles etc.

ExpressMaint command syntax example:

expressmaint -S HOST\SQLEXPRESS -D ALL_USER -T DB -R logpath -RU WEEKS -RV 1 -B backuppath -BU HOURS -BV 3

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

In fact to stopping the service we must use the method stopService() and you are doing in right way:

Start service:

  Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
  startService(myService);

Stop service:

  Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
  stopService(myService);

if you call stopService(), then the method onDestroy() in the service is called (NOT the stopService() method):

  @Override
    public void onDestroy() {
      timer.cancel();
      task.cancel();    
        Log.i(TAG, "onCreate() , service stopped...");
    }

you must implement the onDestroy() method!.

Here is a complete example including how to start/stop the service.

You can try:

apt-cyg install curl

You can use the in operator:

if "blah" not in somestring: 
    continue

            MessageBox.show("Incorrect Email Id.");
        }

Change = to == i.e if (strcmp("hello", "hello") == 0)

You want to compare the result of strcmp() to 0. So you need ==. Assigning it to 0 won't work because rvalues cannot be assigned to.

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

You can have it embedded (build action set to Resource) as well, this is how to retrieve it from there:

private static UnmanagedMemoryStream GetResourceStream(string resName)
{
    var assembly = Assembly.GetExecutingAssembly();
    var strResources = assembly.GetName().Name + ".g.resources";
    var rStream = assembly.GetManifestResourceStream(strResources);
    var resourceReader = new ResourceReader(rStream);
    var items = resourceReader.OfType<DictionaryEntry>();
    var stream = items.First(x => (x.Key as string) == resName.ToLower()).Value;
    return (UnmanagedMemoryStream)stream;
}

private void Button1_Click(object sender, RoutedEventArgs e)
{
    string resName = "Test.txt";
    var file = GetResourceStream(resName);
    using (var reader = new StreamReader(file))
    {
        var line = reader.ReadLine();
        MessageBox.Show(line);
    }
}

Steps that worked for me on Ubuntu 8.04.2 to remove postgres 8.3

1. List All Postgres related packages

   dpkg -l | grep postgres
   
   ii  postgresql                            8.3.17-0ubuntu0.8.04.1           object-relational SQL database (latest versi
   ii  postgresql-8.3                        8.3.9-0ubuntu8.04                object-relational SQL database, version 8.3
   ii  postgresql-client                     8.3.9-0ubuntu8.04                front-end programs for PostgreSQL (latest ve
   ii  postgresql-client-8.3                 8.3.9-0ubuntu8.04                front-end programs for PostgreSQL 8.3
   ii  postgresql-client-common              87ubuntu2                        manager for multiple PostgreSQL client versi
   ii  postgresql-common                     87ubuntu2                        PostgreSQL database-cluster manager
   ii  postgresql-contrib                    8.3.9-0ubuntu8.04                additional facilities for PostgreSQL (latest
   ii  postgresql-contrib-8.3                8.3.9-0ubuntu8.04                additional facilities for PostgreSQL
   

2. Remove all above listed

   sudo apt-get --purge remove postgresql postgresql-8.3  postgresql-client  postgresql-client-8.3 postgresql-client-common postgresql-common  postgresql-contrib postgresql-contrib-8.3
   

3. Remove the following folders

   sudo rm -rf /var/lib/postgresql/
   sudo rm -rf /var/log/postgresql/
   sudo rm -rf /etc/postgresql/
   

Kindly try below on postman :-

Hope this will help someone in future.

The "in" in Linq-To-Sql uses a reverse logic compared to a SQL query.

Let's say you have a list of integers, and want to find the items that match those integers.

int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

var items = from p in context.Items
                 where numbers.Contains(p.ItemId)
                select p;

Anyway, the above works fine in linq-to-sql but not in EF 1.0. Haven't tried it in EF 4.0

You can try something like below

$($.parseHTML(<<table html string variable here>>)).find("td:contains('<<some text to find>>')").first().prev().text();

I know its an old question and lots of answers are helpful but in my case, I faced with the same error unluckily the reason was different. (Spring boot version 2.0.5.RELEASE) If you are using

IntelliJ idea 2018.1.5 or above and you set JDK version as JDK 11

the same exception occurred. After updating the

JDK version as 8

the error is gone.
