Programs & Examples On #Workflow foundation

I was getting the same exception, but in my case I am using PowerShell to run commands So, I fixed this with an instruction to unblock multiple files first. PS C:\> dir C:\executable_file_Path\*PowerShell* | Unblock-File and then use the following to load the package & 'C:\path_to_executable\php.exe' "c:\path_to_composer_.phar_file\composer.phar "require desired/package

It's the null conditional operator. It basically means:

"Evaluate the first operand; if that's null, stop, with a result of null. Otherwise, evaluate the second operand (as a member access of the first operand)."

In your example, the point is that if a is null, then a?.PropertyOfA will evaluate to null rather than throwing an exception - it will then compare that null reference with foo (using string's == overload), find they're not equal and execution will go into the body of the if statement.

In other words, it's like this:

string bar = (a == null ? null : a.PropertyOfA);
if (bar != foo)
{
    ...
}

... except that a is only evaluated once.

Note that this can change the type of the expression, too. For example, consider FileInfo.Length. That's a property of type long, but if you use it with the null conditional operator, you end up with an expression of type long?:

FileInfo fi = ...; // fi could be null
long? length = fi?.Length; // If fi is null, length will be null

const x = {obj1: 1, pass: 2, obj2: 3, obj3:26};

const objectWithoutKey = (object, key) => {
  const {[key]: deletedKey, ...otherKeys} = object;
  return otherKeys;
}

console.log(objectWithoutKey(x, 'pass'));

You cannot play two animations since the attribute can be defined only once. Rather why don't you include the second animation in the first and adjust the keyframes to get the timing right?

Place ojdbc6.jar in your project resources folder of eclipse. then add the following dependency code in your pom.xml

<dependency>
<groupId> oracle </groupId>
 <artifactId>ojdbc6</artifactId>
 <version>11.2.0</version>
  <scope>system</scope>
  <systemPath>${project.basedir}/src/main/resources/ojdbc6.jar</systemPath>
</dependency>

you could use class for all your checkboxes, and do:

$(".check_class").click(function() {
  $(".check_class").attr("checked", false); //uncheck all checkboxes
  $(this).attr("checked", true);  //check the clicked one
});

Netcat sends one packet per newline. So you're fine. If you do anything more complex then you might need something else.

I was fooling around with Wireshark when I realized this. Don't know if it helps.

Another solution is to use a Predicate, then you can use this in any filter:

public static <T> Predicate<T> distinctBy(Function<? super T, ?> f) {
  Set<Object> objects = new ConcurrentHashSet<>();
  return t -> objects.add(f.apply(t));
}

Then simply reuse the predicate anywhere:

employees.stream().filter(distinctBy(e -> e.getId));

Note: in the JavaDoc of filter, which says it takes a stateless Predicte. Actually, this works fine even if the stream is parallel.

About other solutions:

1) Using .collect(Collectors.toConcurrentMap(..)).values() is a good solution, but it's annoying if you want to sort and keep the order.

2) stream.removeIf(e->!seen.add(e.getID())); is also another very good solution. But we need to make sure the collection implemented removeIf, for example it will throw exception if we construct the collection use Arrays.asList(..).

Symmetric Key Cryptography : Symmetric key uses the same key for encryption and decryption. The main challenge with this type of cryptography is the exchange of the secret key between the two parties sender and receiver.

Example : The following example uses symmetric key for encryption and decryption algorithm available as part of the Sun's JCE(Java Cryptography Extension). Sun JCE is has two layers, the crypto API layer and the provider layer.

DES (Data Encryption Standard) was a popular symmetric key algorithm. Presently DES is outdated and considered insecure. Triple DES and a stronger variant of DES. It is a symmetric-key block cipher. There are other algorithms like Blowfish, Twofish and AES(Advanced Encryption Standard). AES is the latest encryption standard over the DES.

Steps :

1. Add the Security Provider : We are using the SunJCE Provider that is available with the JDK.
2. Generate Secret Key : Use KeyGenerator and an algorithm to generate a secret key. We are using DESede.
3. Encode Text : For consistency across platform encode the plain text as byte using UTF-8 encoding.
4. Encrypt Text : Instantiate Cipher with ENCRYPT_MODE, use the secret key and encrypt the bytes.
5. Decrypt Text : Instantiate Cipher with DECRYPT_MODE, use the same secret key and decrypt the bytes.

All the above given steps and concept are same, we just replace algorithms.

import java.util.Base64;    
import javax.crypto.Cipher;  
import javax.crypto.KeyGenerator;   
import javax.crypto.SecretKey;  
public class EncryptionDecryptionAES {  
    static Cipher cipher;  

    public static void main(String[] args) throws Exception {
        /* 
         create key 
         If we need to generate a new key use a KeyGenerator
         If we have existing plaintext key use a SecretKeyFactory
        */ 
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        keyGenerator.init(128); // block size is 128bits
        SecretKey secretKey = keyGenerator.generateKey();

        /*
          Cipher Info
          Algorithm : for the encryption of electronic data
          mode of operation : to avoid repeated blocks encrypt to the same values.
          padding: ensuring messages are the proper length necessary for certain ciphers 
          mode/padding are not used with stream cyphers.  
         */
        cipher = Cipher.getInstance("AES"); //SunJCE provider AES algorithm, mode(optional) and padding schema(optional)  

        String plainText = "AES Symmetric Encryption Decryption";
        System.out.println("Plain Text Before Encryption: " + plainText);

        String encryptedText = encrypt(plainText, secretKey);
        System.out.println("Encrypted Text After Encryption: " + encryptedText);

        String decryptedText = decrypt(encryptedText, secretKey);
        System.out.println("Decrypted Text After Decryption: " + decryptedText);
    }

    public static String encrypt(String plainText, SecretKey secretKey)
            throws Exception {
        byte[] plainTextByte = plainText.getBytes();
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        byte[] encryptedByte = cipher.doFinal(plainTextByte);
        Base64.Encoder encoder = Base64.getEncoder();
        String encryptedText = encoder.encodeToString(encryptedByte);
        return encryptedText;
    }

    public static String decrypt(String encryptedText, SecretKey secretKey)
            throws Exception {
        Base64.Decoder decoder = Base64.getDecoder();
        byte[] encryptedTextByte = decoder.decode(encryptedText);
        cipher.init(Cipher.DECRYPT_MODE, secretKey);
        byte[] decryptedByte = cipher.doFinal(encryptedTextByte);
        String decryptedText = new String(decryptedByte);
        return decryptedText;
    }
}

Output:

Plain Text Before Encryption: AES Symmetric Encryption Decryption
Encrypted Text After Encryption: sY6vkQrWRg0fvRzbqSAYxepeBIXg4AySj7Xh3x4vDv8TBTkNiTfca7wW/dxiMMJl
Decrypted Text After Decryption: AES Symmetric Encryption Decryption

Example: Cipher with two modes, they are encrypt and decrypt. we have to start every time after setting mode to encrypt or decrypt a text.

Edited:

You should really be using openssl_encrypt() & openssl_decrypt()

As Scott says, Mcrypt is not a good idea as it has not been updated since 2007.

There is even an RFC to remove Mcrypt from PHP - https://wiki.php.net/rfc/mcrypt-viking-funeral

You can also specify the exact values for each gr

0 2,10,12,14,16,18,20 * * *

It stands for 2h00, 10h00, 12h00 and so on, till 20h00.

From the above answer, we have:

The comma, ",", means "and". If you are confused by the above line, remember that spaces are the field separators, not commas.

And from (Wikipedia page):

*    *    *    *    *  command to be executed
-    -    -    -    -
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    +----- day of week (0 - 7) (0 or 7 are Sunday, or use names)
¦    ¦    ¦    +---------- month (1 - 12)
¦    ¦    +--------------- day of month (1 - 31)
¦    +-------------------- hour (0 - 23)
+------------------------- min (0 - 59)

Hope it helps :)

EDIT:

• don't miss the 1st 0 (zero) and the following space: it means "the minute zero", you can also set it to 15 (the 15th minute) or expressions like */15 (every minute divisible by 15, i.e. 0,15,30)

It looks like you're writing PHP, in which case you want:

<?
$arr=array('us'=>'United', 'ca'=>'canada');
$key='ca';
echo $arr[$key];
?>

Notice that the ('us'=>'United', 'ca'=>'canada') needs to be a parameter to the array function in PHP.

Most programming languages that support associative arrays or dictionaries use arr['key'] to retrieve the item specified by 'key'

For instance:

Ruby

ruby-1.9.1-p378 > h = {'us' => 'USA', 'ca' => 'Canada' }
 => {"us"=>"USA", "ca"=>"Canada"} 
ruby-1.9.1-p378 > h['ca']
 => "Canada" 

Python

>>> h = {'us':'USA', 'ca':'Canada'}
>>> h['ca']
'Canada'

C#

class P
{
    static void Main()
    {
        var d = new System.Collections.Generic.Dictionary<string, string> { {"us", "USA"}, {"ca", "Canada"}};
        System.Console.WriteLine(d["ca"]);
    }
}

Lua

t = {us='USA', ca='Canada'}
print(t['ca'])
print(t.ca) -- Lua's a little different with tables

Some people argue that a method should have a single point of exit (e.g., only one return). Personally, I think that trying to stick to that rule produces code that's harder to read. In your example, as soon as you find what you were looking for, return it immediately, it's clear and it's efficient.

Quoting the C2 wiki:

The original significance of having a single entry and single exit for a function is that it was part of the original definition of StructuredProgramming as opposed to undisciplined goto SpaghettiCode, and allowed a clean mathematical analysis on that basis.

Now that structured programming has long since won the day, no one particularly cares about that anymore, and the rest of the page is largely about best practices and aesthetics and such, not about mathematical analysis of structured programming constructs.

Perfectly worked for me

jQuery('#datetimepicker1').datetimepicker({
    use24hours: true,   
    format: "YYYY-MM-DD HH:mm ",
    defaultDate: new Date(),
    });

This work for me now and today at Angular version 9

1. Install via npm this: npm i @types/jquery just add --save to setup globally.
2. Go to tsconfig.app.json and add in the array "types" jquery .
3. ng serve and done.

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

Starting with Jackson 2.6, a property can be marked as read- or write-only. It's simpler than hacking the annotations on both accessors and keeps all the information in one place:

public class User {
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private String password;
}

rails generate migration add_index_to_table_name column_name:uniq

or

rails generate migration add_column_name_to_table_name column_name:string:uniq:index

generates

class AddIndexToModerators < ActiveRecord::Migration
  def change
    add_column :moderators, :username, :string
    add_index :moderators, :username, unique: true
  end
end

If you're adding an index to an existing column, remove or comment the add_column line, or put in a check

add_column :moderators, :username, :string unless column_exists? :moderators, :username

that evidently powershell's cmdlets such as copy-item, test-path, etc do not support alternate credentials...

It looks like they do here, copy-item certainly includes a -Credential parameter.

PS C:\> gcm -syn copy-item
Copy-Item [-Path] <String[]> [[-Destination] <String>] [-Container] [-Force] [-Filter <String>] [-I
nclude <String[]>] [-Exclude <String[]>] [-Recurse] [-PassThru] [-Credential <PSCredential>] [...]

If using AngularJS 1.2 you can use 'track by' to tell Angular how to compare objects.

<select 
    ng-model="Choice.SelectedOption"                 
    ng-options="choice.Name for choice in Choice.Options track by choice.ID">
</select>

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

Your datatype is wrong, change datatype for dataType.

Just set the environment variable to the EXACT path to gcc.exe like this:

C:\Program Files (x86)\CodeBlocks\MinGW\bin\gcc.exe

How about

if($_SERVER['REQUEST_METHOD'] == 'POST')

To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.

SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC

If you care for it to be in the same order as before you can use a common table expression for that:

;WITH CTE AS (
    SELECT TOP 1000 *
    FROM [SomeTable]
    ORDER BY MySortColumn DESC
)

SELECT * 
FROM CTE
ORDER BY MySortColumn

The following example validates an XML file and generates the appropriate error or warning.

using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;

public class Sample
{

    public static void Main()
    {
        //Load the XmlSchemaSet.
        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.Add("urn:bookstore-schema", "books.xsd");

        //Validate the file using the schema stored in the schema set.
        //Any elements belonging to the namespace "urn:cd-schema" generate
        //a warning because there is no schema matching that namespace.
        Validate("store.xml", schemaSet);
        Console.ReadLine();
    }

    private static void Validate(String filename, XmlSchemaSet schemaSet)
    {
        Console.WriteLine();
        Console.WriteLine("\r\nValidating XML file {0}...", filename.ToString());

        XmlSchema compiledSchema = null;

        foreach (XmlSchema schema in schemaSet.Schemas())
        {
            compiledSchema = schema;
        }

        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add(compiledSchema);
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
        settings.ValidationType = ValidationType.Schema;

        //Create the schema validating reader.
        XmlReader vreader = XmlReader.Create(filename, settings);

        while (vreader.Read()) { }

        //Close the reader.
        vreader.Close();
    }

    //Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

The preceding example uses the following input files.

Methinks the word "console" is causing the confusion.

If you want to emulate an old-style full/half duplex console, you'd use something like this:

$('console').keyup(function(event){
    $.get("url", { keyCode: event.which }, ... );
    return true;
});

event.which has the key that was pressed. For backspace handling, event.which === 8.

In lieu of explicit initialization, initialization of members in classes works identically to initialization of local variables in functions.

For objects, their default constructor is called. For example, for std::string, the default constructor sets it to an empty string. If the object's class does not have a default constructor, it will be a compile error if you do not explicitly initialize it.

For primitive types (pointers, ints, etc), they are not initialized -- they contain whatever arbitrary junk happened to be at that memory location previously.

For references (e.g. std::string&), it is illegal not to initialize them, and your compiler will complain and refuse to compile such code. References must always be initialized.

So, in your specific case, if they are not explicitly initialized:

    int *ptr;  // Contains junk
    string name;  // Empty string
    string *pname;  // Contains junk
    string &rname;  // Compile error
    const string &crname;  // Compile error
    int age;  // Contains junk

I had the same issue with my Android development using Android studio. Solutions provided are general and did not help me ( at least for me). After hours of research I found following solution and may help to android developers who are doing development using android studio. modify the setting as below Preferences ->Build, Execution, Deployment -> Instant Run -> un-check the first option.

With this change I am up and running. Hope this will help my dev friends.

Alphanumeric characters and all of

~ - _ . ! * ' ( ) ,

are valid within an URL.

All other characters must be encoded.

These are literals and are described in section 3.10 of the Java language spec.

By the use of slice operator with step parameter which would cause evaluation of the queryset and create a list.

list_of_answers = answers[::1]

or initially you could have done:

answers = Answer.objects.filter(id__in=[answer.id for answer in
        answer_set.answers.all()])[::1]

The only thing which worked for me is this

fetchData()
  .subscribe(

    }
  ).add(() => {
       //Called when operation is complete (both success and error)
  });

What about this small piece of code:

function splitME(str, size) {
    let subStr = new RegExp('.{1,' + size + '}', 'g');
    return str.match(subStr);
};

Here's a shell script I made for myself:

#! /bin/sh

for device in `adb devices | awk '{print $1}'`; do
  if [ ! "$device" = "" ] && [ ! "$device" = "List" ]
  then
    echo " "
    echo "adb -s $device $@"
    echo "------------------------------------------------------"
    adb -s $device $@
  fi
done

Try moving the lapsList function out of your class and into your render function:

render() {
  const lapsList = this.state.laps.map((data) => {
    return (
      <View><Text>{data.time}</Text></View>
    )
  })

  return (
    <View style={styles.container}>
      <View style={styles.footer}>
        <View><Text>coucou test</Text></View>
        {lapsList}
      </View>
    </View>
  )
}

#testdiv {
   border-left: 1px solid;
}

See the MDN documentation on border.

I did it this way, where 'struts2ActionName' is the struts2 action in my case. You may use any url instead.

var urlAdditionCert =${pageContext.request.contextPath}/struts2ActionName";
$("#dialogId").load( urlAdditionCert).dialog({
    modal: true,
    height: $("#body").height(),
    width: $("#body").width()*.8
});

Make sure that you add daemon off; to you nginx.conf or run it with CMD ["nginx", "-g", "daemon off;"] as per the official nginx image

Then use the following to run both supervisor as service and nginx as foreground process that will prevent the container from exiting

service supervisor start && nginx

In some cases you will need to have more than one process in your container, so forcing the container to have exactly one process won't work and can create more problems in deployment.

So you need to understand the trade-offs and make your decision accordingly.

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

An alternative approach with vue-cli version 3 is to add a .env file in the root project directory (along side package.json) with the contents:

PORT=3000

Running npm run serve will now indicate the app is running on port 3000.

You can try below code:

$("Your button id or class").live("click", function(){

    $('#detailInfo').html('set your value as you want');

});

Good Luck...

Its important to remember Python 3 has a different way to represent strings - they are byte arrays.

Using Django 1.9 and Python 2.7 and sending the JSON data in the main body (not a header) you would use something like:

mydata = json.loads(request.body)

But for Django 1.9 and Python 3.4 you would use:

mydata = json.loads(request.body.decode("utf-8"))

I just went through this learning curve making my first Py3 Django app!

Hi please check the below link

https://www.postgresql.org/docs/current/xfunc-sql.html

EX:

CREATE FUNCTION sum_n_product_with_tab (x int)
RETURNS TABLE(sum int, product int) AS $$
    SELECT $1 + tab.y, $1 * tab.y FROM tab;
$$ LANGUAGE SQL;

The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.

Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.

In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.

Good way to do this is to use mkdirp module.

$ npm install mkdirp

Use it to run function that requires the directory. Callback is called after path is created or if path did already exists. Error err is set if mkdirp failed to create directory path.

var mkdirp = require('mkdirp');
mkdirp('/tmp/some/path/foo', function(err) { 

    // path exists unless there was an error

});

Utilize the output of built-in repr to deal with \r\n\t and process the output of re.escape is what you want:

re.escape(repr(a)[1:-1]).replace('\\\\', '\\')

As an alternative answer, if you Visual Studio SSDT or possibly Red Gate Sql Compare, you could simply run a schema comparison, script it out, drop the old database (possibly make a backup first in case there would be a reason that you will need that data), and then create a new database with the script created by the comparison tool. While on a very small database this may be more work, on a very large database it will be much quicker to simply drop the database then to deal with the different triggers and constraints that may be on the database.

Table A 
+--------+-----------+
| A-num  | text      | 
|    1   |           |
|    2   |           |
|    3   |           |

|  25  |  04.08.2003  |     4  |
|  26  |  05.03.2003  |     4  |

I will update field text in table A with

UPDATE `Table A`,`Table B`
SET `Table A`.`text`=concat_ws('',`Table A`.`text`,`Table B`.`B-num`," from                                           
",`Table B`.`date`,'/')
WHERE `Table A`.`A-num` = `Table B`.`A-num`

and come to this result:

Table A 
+--------+------------------------+
| A-num  | text                   | 
|    1   |  24 from 03 08 2003 /  |
|    2   |  22 from 01 08 2003 /  |       
|    3   |                        |
|    4   |  25 from 04 08 2003 /  |
|    5   |                        |
--------+-------------------------+

where only one field from Table B is accepted, but I will come to this result:

Table A 
+--------+--------------------------------------------+
| A-num  | text                                       |

        window.history.replaceState({path:newurl},'',newurl);
        }
    }

    function setActiveTab(tab) {
        $('.nav-tabs li').removeClass('active');
        $('.tab-content .tab-pane').removeClass('active');

        $('a[href="#tab-' + tab + '"]').closest('li').addClass('active');
        $('#tab-' + tab).addClass('active');
    }

    // Set active tab
    $url_params = new URLSearchParams(window.location.search);


    // Get active tab and remember it
    $('a[data-toggle="tab"]')
        .on('click', function() {
        $href = $(this).attr('href')
        $active_tab = $href.replace('#tab-', '');

        $url_params.set('tab', $active_tab);
        updateURL($url_params.toString());
    });

    if ($url_params.has('tab')) {
        $tab = $url_params.get('tab');
        $tab = '#tab-' + $tab;
        $myTab = JSON.stringify($tab);
        $thisTab = $('.nav-tabs a[href=' + $myTab  +']');
        $('.nav-tabs a[href=' + $myTab  +']').tab('show');
    }

You can do:

for item in my_list[::-1]:
    print item

(Or whatever you want to do in the for loop.)

The [::-1] slice reverses the list in the for loop (but won't actually modify your list "permanently").

Let's assume you have such history

---o---o---o---M---W---x-------x-------*
              /                      
      ---A---B

Where A, B failed commits and W - is revert of M

So before I start fixing found problems I do cherry-pick of W commit to my branch

git cherry-pick -x W

Then I revert W commit on my branch

git revert W 

After I can continue fixing.

The final history could look like:

---o---o---o---M---W---x-------x-------*
              /                       /     
      ---A---B---W---W`----------C---D

When I send a PR it will clearly shows that PR is undo revert and adds some new commits.

You can also use DBMS_METADATA:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN') 
from dual

You can also go to the bin folder inside your gradle installation folder and correct the JAVA_HOME parameter in gradle.bat file. In my case, my JAVA_HOME was set to c:\Program files\java\bin The JAVA_HOME in gradle.bat was set to %JAVA_HOME%\bin\java.exe.

I corrected the JAVA_HOME in gradle.bat and it worked.

Thank you!!!

If you happen to be using Windows 8 and up, here's how to get to it:

• The newer Microsoft SQL Server Configuration Manager is a snap-in for the Microsoft Management Console program.

• It is not a stand-alone program as used in the previous versions of Microsoft Windows operating systems.

• SQL Server Configuration Manager doesn’t appear as an application when running Windows 8.

• To open SQL Server Configuration Manager, in the Search charm, under Apps, type:

  SQLServerManager15.msc for [SQL Server 2019] or

  SQLServerManager14.msc for [SQL Server 2017] or

  SQLServerManager13.msc for [SQL Server 2016] or

  SQLServerManager12.msc for [SQL Server 2014] or

  SQLServerManager11.msc for [SQL Server 2012] or

  SQLServerManager10.msc for [SQL Server 2008], and then press Enter.

Got to this question because I was looking for a way to select multiple words with mouse click on VS Code, which should be achieved by using alt+click, but this keybinding wasn't working (I think it is something related to my OS, Ubuntu).

NOTE calling parent method via super will only work on parent class, If your parent is interface, and wants to call the default methods then need to add interfaceName before super like IfscName.super.method();

interface Vehicle {
    //Non abstract method
    public default void printVehicleTypeName() { //default keyword can be used only in interface.
        System.out.println("Vehicle");
    }
}


class FordFigo extends FordImpl implements Vehicle, Ford {
    @Override
    public void printVehicleTypeName() { 
        System.out.println("Figo");
        Vehicle.super.printVehicleTypeName();
    }
}

Interface name is needed because same default methods can be available in multiple interface name that this class extends. So explicit call to a method is required.

This is what worked for me

If you can move to SQL Server 2008, you can take advantage of the FILESTREAM support which gives you the best of both - the files are stored in the filesystem, but the database integration is much better than just storing a filepath in a varchar field. Your query can return a standard .NET file stream, which makes the integration a lot simpler.

GNU Rush may be the most flexible and secure way to accomplish this:

GNU Rush is a Restricted User Shell, designed for sites that provide limited remote access to their resources, such as svn or git repositories, scp, or the like. Using a sophisticated configuration file, GNU Rush gives you complete control over the command lines that users execute, as well as over the usage of system resources, such as virtual memory, CPU time, etc.

this code work very well for me: this return the value of selected option. $('#select_id').find('option:selected').val();

Both commands are correct :

mvn clean install -Pdev1
mvn clean install -P dev1

The problem is most likely not profile activation, but the profile not accomplishing what you expect it to.

It is normal that the command :

mvn help:active-profiles

does not display the profile, because is does not contain -Pdev1. You could add it to make the profile appear, but it would be pointless because you would be testing maven itself.

What you should do is check the profile behavior by doing the following :

1. set activeByDefault to true in the profile configuration,
2. run mvn help:active-profiles (to make sure it is effectively activated even without -Pdev1),
3. run mvn install.

It should give the same results as before, and therefore confirm that the problem is the profile not doing what you expect.

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

You're almost there. Simply use:

//form[@id='myform']//input[@type='submit']

The // shortcut can also be used inside an expression.

The include path is set against the server configuration (PHP.ini) but the include path you specify is relative to that path so in your case the include path is (actual path in windows):

C:\xampp\php\PEAR\initcontrols\header_myworks.php

providing the path you pasted in the subject is correct. Make sure your file is located there.

For more info you can get and set the include path programmatically.

You have to include the expression for your calculated column:

SELECT  
ColumnA,  
ColumnB,  
ColumnA + ColumnB AS calccolumn1  
(ColumnA + ColumnB) / ColumnC AS calccolumn2

overflow-x: hidden; works perfect for me.

All these methods don't modify original value, returns new strings.

var city_name = 'Some text with spaces';

Replaces 1st space with _

city_name.replace(' ', '_'); // Returns: Some_text with spaces

Replaces all spaces with _ using regex. If you need to use regex, then i recommend testing it with https://regex101.com/

city_name.replace(/ /gi,'_');  // Returns: Some_text_with_spaces 

Replaces all spaces with _ without regex. Functional way.

city_name.split(' ').join('_');  // Returns: Some_text_with_spaces

Most answers here explain conceptual difference and implementation details of both. However I was unable to find explanation about difference in application which IMO is the most important and the OP asked about. So let me reopen this topic...

Once someone told me that its how you use it that makes a difference!

Exactly. In 90% cases you can obtain object reference using either Factory or DI and usually you end up with latter. In another 10% cases using Factory is only correct way. These cases include obtaining objects by variable at runtime parameters. Like this:

IWebClient client = factoryWithCache.GetWebClient(url: "stackoverflow.com",
        useCookies: false, connectionTimeout: 120);

In this case getting client from DI is not possible (or at least requires some ugly workaround). So as a general rule to make decision: if a dependency can be obtained without any runtime calculated parameters then DI is preferred, otherwise use Factory.

                "arn:aws:s3:::your_bucket_name/*"
            ]
        }
    ]
}

Adding both "arn:aws:s3:::your_bucket_name" and "arn:aws:s3:::your_bucket_name/*" to policy congiguration fixed the issue for me.

Convert.ChangeType() doesn't correctly handle nullable types or enumerations in .NET 2.0 BCL (I think it's fixed for BCL 4.0 though). Rather than make the outer implementation more complex, make the converter do more work for you. Here's an implementation I use:

public static class Converter
{
  public static T ConvertTo<T>(object value)
  {
    return ConvertTo(value, default(T));
  }

  public static T ConvertTo<T>(object value, T defaultValue)
  {
    if (value == DBNull.Value)
    {
      return defaultValue;
    }
    return (T) ChangeType(value, typeof(T));
  }

  public static object ChangeType(object value, Type conversionType)
  {
    if (conversionType == null)
    {
      throw new ArgumentNullException("conversionType");
    }

    // if it's not a nullable type, just pass through the parameters to Convert.ChangeType
    if (conversionType.IsGenericType && conversionType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
    {
      // null input returns null output regardless of base type
      if (value == null)
      {
        return null;
      }

      // it's a nullable type, and not null, which means it can be converted to its underlying type,
      // so overwrite the passed-in conversion type with this underlying type
      conversionType = Nullable.GetUnderlyingType(conversionType);
    }
    else if (conversionType.IsEnum)
    {
      // strings require Parse method
      if (value is string)
      {
        return Enum.Parse(conversionType, (string) value);          
      }
      // primitive types can be instantiated using ToObject
      else if (value is int || value is uint || value is short || value is ushort || 
           value is byte || value is sbyte || value is long || value is ulong)
      {
        return Enum.ToObject(conversionType, value);
      }
      else
      {
        throw new ArgumentException(String.Format("Value cannot be converted to {0} - current type is " +
                              "not supported for enum conversions.", conversionType.FullName));
      }
    }

    return Convert.ChangeType(value, conversionType);
  }
}

Then your implementation of GetQueryString<T> can be:

public static T GetQueryString<T>(string key)
{
    T result = default(T);
    string value = HttpContext.Current.Request.QueryString[key];

    if (!String.IsNullOrEmpty(value))
    {
        try
        {
            result = Converter.ConvertTo<T>(value);  
        }
        catch
        {
            //Could not convert.  Pass back default value...
            result = default(T);
        }
    }

    return result;
}

Yes, this is possible by using worksheet events:

In the Visual Basic Editor open the worksheet you're interested in (i.e. "BigBoard") by double clicking on the name of the worksheet in the tree at the top left. Place the following code in the module:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Intersect(Target, Me.Range("D2")) Is Nothing Then Exit Sub
        Application.EnableEvents = False 'to prevent endless loop
        On Error Goto Finalize 'to re-enable the events      
        MsgBox "You changed THE CELL!"
    End If
Finalize:        
    Application.EnableEvents = True
End Sub

I hope to give a really short answer:

seed make (the next series) random numbers predictable. You can think every time after you call seed, it pre-defines series numbers and numpy random keeps the iterator of it, then every time you get a random number it just gonna call get next.

e.g.:

np.random.seed(2)
np.random.randn(2) # array([-0.41675785, -0.05626683])
np.random.randn(1) # array([-1.24528809])

np.random.seed(2)
np.random.randn(1) # array([-0.41675785])
np.random.randn(2) # array([-0.05626683, -1.24528809])

You can notice when I set the same seed, no matter how many random number you request from numpy each time, it always gives the same series of numbers, in this case which is array([-0.41675785, -0.05626683, -1.24528809]).

It is possible to save a "list" of labels in keras model directly. This way the user who uses the model for predictions and does not have any other sources of information can perform the lookup himself. Here is a dummy example of how one can perform an "injection" of labels

# assume we get labels as list
labels = ["cat","dog","horse","tomato"]
# here we start building our model with input image 299x299 and one output layer
xx = Input(shape=(299,299,3))
flat = Flatten()(xx)
output = Dense(shape=(4))(flat)
# here we perform injection of labels
tf_labels = tf.constant([labels],dtype="string")
tf_labels = tf.tile(labels,[tf.shape(xx)[0],1])
output_labels = Lambda(lambda x: tf_labels,name="label_injection")(xx)
#and finaly creating a model
model=tf.keras.Model(xx,[output,output_labels])

When used for prediction, this model returns tensor of scores and tensot of string labels. Model like this can be saved to h5. In this case the file contains the labels. This model can also be exported to saved_model and used for serving in the cloud.

You do it by stacking case labels:

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7: 
    case 12:
    ...
    break;
    ...
}

you can also use the randomizeMatrix function in the R package picante

example:

test <- matrix(c(1,1,0,1,0,1,0,0,1,0,0,1,0,1,0,0),nrow=4,ncol=4)
> test
     [,1] [,2] [,3] [,4]
[1,]    1    0    1    0
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "frequency",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    0    1    0    1
[2,]    1    0    0    0
[3,]    1    0    1    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "richness",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    1    0    0    1
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0
> 

The option null.model="frequency" maintains column sums and richness maintains row sums. Though mainly used for randomizing species presence absence datasets in community ecology it works well here.

This function has other null model options as well, check out following link for more details (page 36) of the picante documentation

    Row row=sheet.getRow(0);
    CellStyle style=null;

    XSSFFont defaultFont= wb.createFont();
    defaultFont.setFontHeightInPoints((short)10);
    defaultFont.setFontName("Arial");
    defaultFont.setColor(IndexedColors.BLACK.getIndex());
    defaultFont.setBold(false);
    defaultFont.setItalic(false);

    XSSFFont font= wb.createFont();
    font.setFontHeightInPoints((short)10);
    font.setFontName("Arial");
    font.setColor(IndexedColors.WHITE.getIndex());
    font.setBold(true);
    font.setItalic(false);

    style=row.getRowStyle();
    style.setFillBackgroundColor(IndexedColors.DARK_BLUE.getIndex());
    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);
    style.setFont(font);

If you do not create defaultFont all your workbook will be using the other one as default.

You can set up a background with your GIF file and set the body this way:

body{
background-image:url('http://www.example.com/yourfile.gif');
background-position: center;
background-size: cover;
}

Change background image URL with your GIF. With background-position: center you can put the image to the center and with background-size: cover you set the picture to fit all the screen. You can also set background-size: contain if you want to fit the picture at 100% of the screen but without leaving any part of the picture without showing.

http://www.w3schools.com/cssref/css3_pr_background-size.asp

Hope it helps :)

Here’s how:

using System.Runtime.InteropServices;

[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

const int SW_HIDE = 0;
const int SW_SHOW = 5;

var handle = GetConsoleWindow();

// Hide
ShowWindow(handle, SW_HIDE);

// Show
ShowWindow(handle, SW_SHOW);

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

You can use the inbuilt readline package, see docs here. I use stream to create a new output stream.

var fs = require('fs'),
    readline = require('readline'),
    stream = require('stream');

var instream = fs.createReadStream('/path/to/file');
var outstream = new stream;
outstream.readable = true;
outstream.writable = true;

var rl = readline.createInterface({
    input: instream,
    output: outstream,
    terminal: false
});

rl.on('line', function(line) {
    console.log(line);
    //Do your stuff ...
    //Then write to outstream
    rl.write(cubestuff);
});

Large files will take some time to process. Do tell if it works.

Use PHP_EOL which outputs \r\n or \n depending on the OS.

You may wish to consider self-certifying your projects:

Self-certification, digital certificate, digital signatures

I didn't think your question was very clear, but if all you need is a unique file name...

import uuid

unique_filename = str(uuid.uuid4())

as noted here, this is what worked best for me:

sudo apt-get install python3 python3-pip python3-setuptools

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10

Since this is a matter of finding files, let's use find!

Using GNU find you can use the -regex option to find those files in the tree of directories whose extension is either .h or .cpp:

find -type f -regex ".*\.\(h\|cpp\)"
#            ^^^^^^^^^^^^^^^^^^^^^^^

Then, it is just a matter of executing grep on each of its results:

find -type f -regex ".*\.\(h\|cpp\)" -exec grep "your pattern" {} +

If you don't have this distribution of find you have to use an approach like Amir Afghani's, using -o to concatenate options (the name is either ending with .h or with .cpp):

find -type f \( -name '*.h' -o -name '*.cpp' \) -exec grep "your pattern" {} +
#            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And if you really want to use grep, follow the syntax indicated to --include:

grep "your pattern" -r --include=*.{cpp,h}
#                      ^^^^^^^^^^^^^^^^^^^

function getCheckedValue(radioObj, name) {

    for (j = 0; j < radioObj.rows.length; ++j) {
        for (k = 0; k < radioObj.cells.length; ++k) {
            var radioChoice = document.getElementById(name + "_" + k);
            if (radioChoice.checked) {
                return radioChoice.value;
            }
        }
    }
    return "";
}

The whole point of getting things out as IEnumerable is so you can lazily iterate over the contents. As such, there isn't really a concept of an index. What you are doing really doesn't make a lot of sense for an IEnumerable. If you need something that supports access by index, put it in an actual list or collection.

I always do this to download the packages:

pip install --download /path/to/download/to_packagename

OR

pip install --download=/path/to/packages/downloaded -r requirements.txt

And when I want to install all of those libraries I just downloaded, I do this:

pip install --no-index --find-links="/path/to/downloaded/dependencies" packagename

OR

pip install --no-index --find-links="/path/to/downloaded/packages" -r requirements.txt

Update

Also, to get all the packages installed on one system, you can export them all to requirement.txt that will be used to intall them on another system, we do this:

pip freeze > requirement.txt

Then, the requirement.txt can be used as above for download, or do this to install them from requirement.txt:

pip install -r requirement.txt

REFERENCE: pip installer

You can use toSql method - the easiest way

DB::table('users')->toSql();

And also if you have bindings in your query and want to see the query with bindings. You cant use somthing like that:

$query = DB::table('table')->whereIn('some_field', [1,2,30]); 

$sql_with_bindings = str_replace_array('?', $query->getBindings(), $query->toSql());

dd($sql_with_bindings);

On heroku server (readonly filesystem), If you want runtime compilation of css (its not recommended but you can do it), make sure you have done settings like below -

# inside config/application.rb
config.assets.enabled = true
config.assets.prefix = Rails.root.join('tmp/assets').to_s

# If you are using sass then keep gem outside of asset group
 gem 'sass-rails',   '3.1.4'

# inside config/environments/production.rb
config.assets.compile = true

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

In my particular case, I have PHP configured to use PHP-FPM (FastCGI Process Manager). When executing phpinfo() from CLI I saw correct timezone that I had set in the php.ini, however it was still incorrect in the browser and causing my code to fail. I simply needed to restart the php-fpm service on the server.

service rh-php56-php-fpm restart

You may also need to restart the httpd service if you edited the php.ini

service httpd restart

What is the difference between Attribute and Property?
What is the difference between Feature and Function? What is the difference between Characteristic and Character? What is the difference between Act and Behavior?

Its just a change in context.

Object,Product,Personality,Person

A Person Acts in a Behavior. A Personality has Characteristics of a given Character. A Product has Feature that derive Functionality. An Object had Attributes that give it Properties.

For what purpose is this function useful?

One particular usage is counting with a dictionary. Let's assume you want to count the number of occurrences of each element in a given list. The common way to do so is to make a dictionary where keys are elements and values are the number of occurrences.

fruits = ['apple', 'banana', 'peach', 'apple', 'pear']
d = {}
for fruit in fruits:
    if fruit not in d:
        d[fruit] = 0
    d[fruit] += 1

Using the .get() method, you can make this code more compact and clear:

for fruit in fruits:
    d[fruit] = d.get(fruit, 0) + 1

I like RDC's response, but why limit the JSON returned to have only arrays at the top level? I needed to allow a dictionary at the top level, so I modified it thus:

extension String
{
    var parseJSONString: AnyObject?
    {
        let data = self.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

        if let jsonData = data
        {
            // Will return an object or nil if JSON decoding fails
            do
            {
                let message = try NSJSONSerialization.JSONObjectWithData(jsonData, options:.MutableContainers)
                if let jsonResult = message as? NSMutableArray {
                    return jsonResult //Will return the json array output
                } else if let jsonResult = message as? NSMutableDictionary {
                    return jsonResult //Will return the json dictionary output
                } else {
                    return nil
                }
            }
            catch let error as NSError
            {
                print("An error occurred: \(error)")
                return nil
            }
        }
        else
        {
            // Lossless conversion of the string was not possible
            return nil
        }
    }

Open command prompt with admin access and type the following commands there .

a)

tasklist

it displays list of all available services . There you can see the service you want to stop/start/restart . Remember PID value of the service you want to force stop.

b) Now type

taskkill /f /PID [PID value of the service] 

and press enter. On success you will get the message “SUCCESS: The process with PID has been terminated”.

Ex : taskkill /f /PID 5088

This will forcibly kill the frozen service. You can now return to Server Manager and restart the service.

Try:

pwd=`pwd`

or

pwd=$(pwd)

Notice no spaces after the equals sign.

Also as Mr. Weiss points out; you don't assign to $pwd, you assign to pwd.

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

I noticed one error in Dave Ward's answer (perhaps a recent change?): The query string paramaters are in request.query, not request.params. (See https://stackoverflow.com/a/6913287/166530 )

request.params by default is filled with the value of any "component matches" in routes, i.e.

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

and, if you have configured express to use its bodyparser (app.use(express.bodyParser());) also with POST'ed formdata. (See How to retrieve POST query parameters? )

You can add the application folder to your path from a command prompt using:

setx PATH "%PATH%;c:\MinGW\bin"

Note that you will probably need to open a new command window for the modified path setting to go into effect.

This assumes that the content is in column B on each sheet (since it's not clear how you determine the column on each sheet.) and the last row of that column is also the last row of the sheet.

$xlCellTypeLastCell = 11 
$startRow = 5 
$col = 2 

$excel = New-Object -Com Excel.Application
$wb = $excel.Workbooks.Open("C:\Users\Administrator\my_test.xls")

for ($i = 1; $i -le $wb.Sheets.Count; $i++)
{
    $sh = $wb.Sheets.Item($i)
    $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
    $city = $sh.Cells.Item($startRow, $col).Value2
    $rangeAddress = $sh.Cells.Item($startRow + 1, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
    $sh.Range($rangeAddress).Value2 | foreach 
    {
        New-Object PSObject -Property @{ City = $city; Area = $_ }
    }
}

$excel.Workbooks.Close()

If you read a list from text file, you may get the last empty line as a list element. You can get rid of it like this:

list.pop()
for i in list:
   i[12]=....

I found a solution.

background-size:100% auto;

The function returns a static 2D array

const int N = 6;
int (*(MakeGridOfCounts)())[N] {
 static int cGrid[N][N] = {{0, }, {0, }, {0, }, {0, }, {0, }, {0, }};
 return cGrid;
}

int main() {
int (*arr)[N];
arr = MakeGridOfCounts();
}

You need to make the array static since it will be having a block scope, when the function call ends, the array will be created and destroyed. Static scope variables last till the end of program.

Just add parenthesis around the query:

set @user = 123456;
set @group = (select GROUP from USER where User = @user);
select * from USER where GROUP = @group;

Make sure that you are zipping all dependencies in a folder structure as python/[Your All Dependencies] to make it work as per this documentation.

https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html#configuration-layers-path

You have to look how this is called:

someObject.equals(someOtherObj); 

This invokes the equals method on the instance of someObject. Now, inside that method:

public boolean equals(Object obj) {   if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj?     return true;//If so, these are the same objects, and return true   } 

You can see that this is referring to the instance of the object that equals is called on. Note that equals() is non-static, and so must be called only on objects that have been instantiated.

Note that == is only checking to see if there is referential equality; that is, the reference of this and obj are pointing to the same place in memory. Such references are naturally equal:

Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place 

Further note that equals() is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:

FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing. 

Try git checkout -f master.

When switching branches, proceed even if the index or the working tree differs from HEAD. This is used to throw away local changes.

When checking out paths from the index, do not fail upon unmerged entries; instead, unmerged entries are ignored.

When back button is pressed, ignore interactive pop with screen edge gesture.

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    
    if isMovingFromParent, transitionCoordinator?.isInteractive == false {
      // code here
    }
  }

The accepted answer has a couple of shortcomings:

• Don't target IDs in your JavaScript code. Use classes and data attributes to avoid repeating your code.
• It is good practice to hide with CSS on load rather than with JavaScript—to support non-JavaScript users, and prevent a show-hide flicker on load.

Considering the above, your options could even have different values, but toggle the same class:

<select class="div-toggle" data-target=".my-info-1">
  <option value="orange" data-show=".citrus">Orange</option>
  <option value="lemon" data-show=".citrus">Lemon</option>
  <option value="apple" data-show=".pome">Apple</option>
  <option value="pear" data-show=".pome">Pear</option>
</select>

<div class="my-info-1">
  <div class="citrus hide">Citrus is...</div>
  <div class="pome hide">A pome is...</div>
</div>

jQuery:

$(document).on('change', '.div-toggle', function() {
  var target = $(this).data('target');
  var show = $("option:selected", this).data('show');
  $(target).children().addClass('hide');
  $(show).removeClass('hide');
});
$(document).ready(function(){
    $('.div-toggle').trigger('change');
});

CSS:

.hide {
  display: none;
}

Here's a JSFiddle to see it in action.

The function below works perfectly for me:

// Note this *is* JQuery, see below for JS solution instead
function replaceText(selector, text, newText, flags) {
  var matcher = new RegExp(text, flags);
  $(selector).each(function () {
    var $this = $(this);
    if (!$this.children().length)
       $this.text($this.text().replace(matcher, newText));
  });
}

Here's a usage example:

function replaceAllText() {
  replaceText('*', 'hello', 'hi', 'g');
}

$(document).ready(replaceAllText);
$('html').ajaxStop(replaceAllText);

You can also use do a direct replacement like so:

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

But be careful with it since it may affect the tags, css and scripts as well.

EDIT: As for a pure JavaScript solution use this method instead:

function replaceText(selector, text, newText, flags) {
  var matcher = new RegExp(text, flags);
  var elems = document.querySelectorAll(selector), i;

  for (i = 0; i < elems.length; i++)
    if (!elems[i].childNodes.length)
      elems[i].innerHTML = elems[i].innerHTML.replace(matcher, newText);
}

This is very easy to use, just copy-paste the code. You can use your own star image in background.

I have created a variable var userRating. you can use this variable to get value from stars.

Enjoy!! :)

CSS properties should be set by cssText property or setAttribute method.

// Set multiple styles in a single statement
elt.style.cssText = "color: blue; border: 1px solid black"; 
// Or
elt.setAttribute("style", "color:red; border: 1px solid blue;");

Styles should not be set by assigning a string directly to the style property (as in elt.style = "color: blue;"), since it is considered read-only, as the style attribute returns a CSSStyleDeclaration object which is also read-only.

npm >= 2.0.0

This feature was implemented in the version 2.0.0 of npm. Example:

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

Any of the following paths are also valid:

../foo/bar
~/foo/bar
./foo/bar
/foo/bar

The local package will be copied to the prefix (./node-modules).

npm < 2.0.0

Put somelocallib as dependency in your package.json as normal:

"dependencies": {
  "somelocallib": "0.0.x"
}

Then run npm link ../somelocallib and npm will install the version you're working on as a symlink.

[email protected] /private/tmp/app
+-- [email protected] -> /private/tmp/somelocallib

My best advice would be that there is no standard tree data structure because there are so many ways you could implement it that it would be impossible to cover all bases with one solution. The more specific a solution, the less likely it is applicable to any given problem. I even get annoyed with LinkedList - what if I want a circular linked list?

The basic structure you'll need to implement will be a collection of nodes, and here are some options to get you started. Let's assume that the class Node is the base class of the entire solution.

If you need to only navigate down the tree, then a Node class needs a List of children.

If you need to navigate up the tree, then the Node class needs a link to its parent node.

Build an AddChild method that takes care of all the minutia of these two points and any other business logic that must be implemented (child limits, sorting the children, etc.)

I try almost everything in here to solve this problem... I share here the answer that help me:

Another way to resolve the issue :

• in IIS console, go to application pool managing your site, and note the identity running it (usually Network Service)
• make sure this identity can read KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog (rigth-click, authorisations)
• now change the identity of this application pool to Local System, apply, and switch back to Network Service

Credentials will be reloaded and EventLog reacheable

$('#dialog').draggable({ handle: "#tblOverlay" , scroll: false });

    // Pop up Window 
          <div id="dialog">

2. scroll : Prevent popup window to go beyond parent page or out of current screen.

For somebody who is interested in a such map because you want to reduce footprint of autoboxing in Java of wrappers over primitives types, I would recommend to use Eclipse collections. Trove isn't supported any more, and I believe it is quite unreliable library in this sense (though it is quite popular anyway) and couldn't be compared with Eclipse collections.

import org.eclipse.collections.impl.map.mutable.primitive.IntObjectHashMap;

public class Check {
    public static void main(String[] args) {
        IntObjectHashMap map = new IntObjectHashMap();

        map.put(5,"It works");
        map.put(6,"without");
        map.put(7,"boxing!");

        System.out.println(map.get(5));
        System.out.println(map.get(6));
        System.out.println(map.get(7));
    }
}

In this example above IntObjectHashMap.

As you need int->object mapping, also consider usage of YourObjectType[] array or List<YourObjectType> and access values by index, as map is, by nature, an associative array with int type as index.

new Operator

• This is used to create object from a constructor function
• The new keywords also executes the constructor function

function Car() {
  console.log(this) // this points to myCar
  this.name = "Honda";
}

var myCar = new Car()
console.log(myCar) // Car {name: "Honda", constructor: Object}
console.log(myCar.name) // Honda
console.log(myCar instanceof Car) // true
console.log(myCar.constructor) // function Car() {}
console.log(myCar.constructor === Car) // true
console.log(typeof myCar) // object

Object.create

• You can also use Object.create to create a new object
• But, it does not execute the constructor function
• Object.create is used to create an object from another object

const Car = {
  name: "Honda"
}

var myCar = Object.create(Car)
console.log(myCar) // Object {}
console.log(myCar.name) // Honda
console.log(myCar instanceof Car) // ERROR
console.log(myCar.constructor) // Anonymous function object
console.log(myCar.constructor === Car) // false
console.log(typeof myCar) // object

They are the same.

Both mean that when coming in to the load balancer, the request will be directed to the server that served the first request (and has the session).

YES it is almost possible to forced you have to call to methods in the same order and at the same time this ones are:

System.gc ();
System.runFinalization ();

even if is just one object to clean the use of this two methods at the same time force the garbage collector to use the finalise() method of unreachable object freeing the memory assigned and doing what the finalize() method states.

HOWEVER it is a terrible practice to use the garbage collector because the use of it could introduce an over load to the software that may be even worst than on the memory, the garbage collector has his own thread which is not possible to control plus depending on the algorithm used by the gc could take more time and is consider very inefficient, you should check your software if it worst with the help of the gc because it is definitely broke, a good solution must not depend on the gc.

NOTE: just to keep on mind this will works only if in the finalize method is not a reassignment of the object, if this happens the object will keep alive an it will have a resurrection which is technically possible.

You can use .filter() or .find(). One difference that filter will iterate over all items and returns any which passes the condition as array while find will return the first matched item and break the iteration.

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

If you need only display the trimmed value then I'd suggest against manipulating the original string and using a filter instead.

app.filter('trim', function () {
    return function(value) {
        if(!angular.isString(value)) {
            return value;
        }  
        return value.replace(/^\s+|\s+$/g, ''); // you could use .trim, but it's not going to work in IE<9
    };
});

And then

<span>{{ foo | trim }}</span>

The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...

 // pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {
    return new Date(anyDateInMonth.getFullYear(), 
                    anyDateInMonth.getMonth()+1, 
                    0).getDate();}

If you are creating an array whose main feature is it's length, rather than the value of each index, defining an array as var a=Array(length); is appropriate.

eg-

String.prototype.repeat= function(n){
    n= n || 1;
    return Array(n+1).join(this);
}

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

Example:

parser.add_argument('-s', '--simulate', action='store_true')

This is a typical scenario where subtype polymorphism helps. Do the following

interface I {
  void do();
}

class A implements I { void do() { doA() } ... }
class B implements I { void do() { doB() } ... }
class C implements I { void do() { doC() } ... }

Then you can simply call do() on this.

If you are not free to change A, B, and C, you could apply the visitor pattern to achieve the same.

add this css in your stylesheet

        -o-background-size: cover;
        margin: 0;
        padding: 0;
    }

FIDDLE

Here's a clean solution:

function test(str){
    //Note: should be /(abc)|(def)/i if you want it case insensitive
    var pattern = /(abc)|(def)/;
    return !str.match(pattern);
}

Java 7 introduced stricter verification and changed the class format a bit—to contain a stack map used to verify that code is correct. The exception you see means that some method doesn't have a valid stack map.

Java version or bytecode instrumentation could both be to blame. Usually this means that a library used by the application generates invalid bytecode that doesn't pass the stricter verification. So nothing else than reporting it as a bug to the library can be done by the developer.

As a workaround you can add -noverify to the JVM arguments in order to disable verification. In Java 7 it was also possible to use -XX:-UseSplitVerifier to use the less strict verification method, but that option was removed in Java 8.

I solved this issue by installing the Nuget package: Microsoft ASP.NET Web API 2.2 Client Libraries. This in turn installed newtonsoft.json version 6.04

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

brbcoding have been able to help me with the appropriate coding i needed, here is it

HTML

<input type="checkbox" id="checkme"/>
  <input type="submit" name="sendNewSms" class="inputButton" disabled="disabled" id="sendNewSms" value=" Send " />

Javascript

 var checker = document.getElementById('checkme');
 var sendbtn = document.getElementById('sendNewSms');
 // when unchecked or checked, run the function
 checker.onchange = function(){
if(this.checked){
    sendbtn.disabled = false;
} else {
    sendbtn.disabled = true;
}

}

Somebody was asking about list of formatting mailing addresses, and I think this is what he was looking for...

Frank's Compulsive Guide to Postal Addresses: http://www.columbia.edu/~fdc/postal/ Doesn't help much with street-level issues, however.

My work uses a couple of tools to assist with this: - Lexis-Nexis services, including NCOA lookups (you'll get address standardization for "free") - "Melissa Data" http://www.melissadata.com

Had the error today on a 12c and none of the existing answers fit (no duplicates, no non-deterministic expressions in the WHERE clause). My case was related to that other possible cause of the error, according to Oracle's message text (emphasis below):

ORA-30926: unable to get a stable set of rows in the source tables
Cause: A stable set of rows could not be got because of large dml activity or a non-deterministic where clause.

The merge was part of a larger batch, and was executed on a live database with many concurrent users. There was no need to change the statement. I just committed the transaction before the merge, then ran the merge separately, and committed again. So the solution was found in the suggested action of the message:

Action: Remove any non-deterministic where clauses and reissue the dml.

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

Use the body.onload event instead, either via attribute (<body onload="myFn()"> ...) or by binding an event in Javascript. This is extremely common with jQuery:

$(document).ready(function() {
    doSomething($('#myDiv'));
});

see http://api.jquery.com/prev/

var link = $("#me").parent("div").prev("h3").find("b");
alert(link.text());

Not completely entirely a direct answer to the original question, but relevant for the curious quickly trying to visually understand their cookie information storage planning without implementing a complex limiter algorithm, this string is 4096 ASCII character bytes:

"abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmn"

This isn't much of an answer, but I'd say that works just fine, personally

Having said that, since it doesn't matter what the values are (you've used 0, 1, 2), I'd use a meaningful string in case you ever wanted to output the current value.

Here is a simple example of chaining decorators. Note the last line - it shows what is going on under the covers.

############################################################
#
#    decorators
#
############################################################

def bold(fn):
    def decorate():
        # surround with bold tags before calling original function
        return "<b>" + fn() + "</b>"
    return decorate


def uk(fn):
    def decorate():
        # swap month and day
        fields = fn().split('/')
        date = fields[1] + "/" + fields[0] + "/" + fields[2]
        return date
    return decorate

import datetime
def getDate():
    now = datetime.datetime.now()
    return "%d/%d/%d" % (now.day, now.month, now.year)

@bold
def getBoldDate(): 
    return getDate()

@uk
def getUkDate():
    return getDate()

@bold
@uk
def getBoldUkDate():
    return getDate()


print getDate()
print getBoldDate()
print getUkDate()
print getBoldUkDate()
# what is happening under the covers
print bold(uk(getDate))()

The output looks like:

17/6/2013
<b>17/6/2013</b>
6/17/2013
<b>6/17/2013</b>
<b>6/17/2013</b>

I was having the issue previously in XAMPP localhost with phpmyadmin version 4.2.11.

Increasing the timeout in php.ini didn't helped either.

Then I edited xampp\phpMyAdmin\libraries\config.default.php to change the value of $cfg['ExecTimeLimit'], which was 300 by default.

That solved my issue.

Re-migrate approach for a cleaner plate.

This can painlessly be done IF other apps do not foreign key models from the app to be renamed. Check and make sure their migration files don't list any migrations from this one.

1. Backup your database. Dump all tables with a) data + schema for possible circular dependencies, and b) just data for reloading.
2. Run your tests.
3. Check all code into VCS.
4. Delete the database tables of the app to be renamed.
5. Delete the permissions: delete from auth_permission where content_type_id in (select id from django_content_type where app_label = '<OldAppName>')
6. Delete content types: delete from django_content_type where app_label = '<OldAppName>'
7. Rename the folder of the app.
8. Change any references to your app in their dependencies, i.e. the app's views.py, urls.py , 'manage.py' , and settings.py files.
9. Delete migrations: delete from django_migrations where app = '<OldAppName>'
10. If your models.py 's Meta Class has app_name listed, make sure to rename that too (mentioned by @will).
11. If you've namespaced your static or templates folders inside your app, you'll also need to rename those. For example, rename old_app/static/old_app to new_app/static/new_app.
12. If you defined app config in apps.py; rename those, and rename their references in settings.INSTALLED_APPS
13. Delete migration files.
14. Re-make migrations, and migrate.
15. Load your table data from backups.

Java. Matrix multiplication.

For me this worked:

INSERT INTO [MyTable]

           ,'2023-01-27 14:52:50.000')

If you are using underscoreJs then you can simply use _.isEqual function and it compares all keys and values at each and every level of hierarchy like below example.

var object = {"status":"inserted","id":"5799acb792b0525e05ba074c","data":{"workout":[{"set":[{"setNo":1,"exercises":[{"name":"hjkh","type":"Reps","category":"Cardio","set":{"reps":5}}],"isLastSet":false,"index":0,"isStart":true,"startDuration":1469689001989,"isEnd":true,"endDuration":1469689003323,"speed":"00:00:01"}],"setType":"Set","isSuper":false,"index":0}],"time":"2016-07-28T06:56:52.800Z"}};

var object1 = {"status":"inserted","id":"5799acb792b0525e05ba074c","data":{"workout":[{"set":[{"setNo":1,"exercises":[{"name":"hjkh","type":"Reps","category":"Cardio","set":{"reps":5}}],"isLastSet":false,"index":0,"isStart":true,"startDuration":1469689001989,"isEnd":true,"endDuration":1469689003323,"speed":"00:00:01"}],"setType":"Set","isSuper":false,"index":0}],"time":"2016-07-28T06:56:52.800Z"}};

console.log(_.isEqual(object, object1));//return true

If all the keys and values for those keys are same in both the objects then it will return true, otherwise return false.

If you want to run the scripts in parallel and give them different arguments you can do like below.

import os
os.system("python script.py arg1 arg2 & python script.py arg11 arg22")

just as a .crt file is in .pem format, a .key file is also stored in .pem format. Assuming that the cert is the only thing in the .crt file (there may be root certs in there), you can just change the name to .pem. The same goes for a .key file. Which means of course that you can rename the .pem file to .key.

Which makes gtrig's answer the correct one. I just thought I'd explain why.

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

//import com.google.gson.JsonObject;  
JsonObject complaint = new JsonObject();
complaint.addProperty("key", "value");

Here's a simple method to do it: The (ip >> 8), (ip >> 16) and (ip >> 24) moves the 2nd, 3rd and 4th bytes into the lower order byte, while the & 0xFF isolates the least significant byte at each step.

void print_ip(unsigned int ip)
{
    unsigned char bytes[4];
    bytes[0] = ip & 0xFF;
    bytes[1] = (ip >> 8) & 0xFF;
    bytes[2] = (ip >> 16) & 0xFF;
    bytes[3] = (ip >> 24) & 0xFF;   
    printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);        
}

There is an implied bytes[0] = (ip >> 0) & 0xFF; at the first step.

Use snprintf() to print it to a string.

var newDate = new Date();
newDate.setTime(unixtime*1000);
dateString = newDate.toUTCString();

Where unixtime is the time returned by your sql db. Here is a fiddle if it helps.

For example, using it for the current time:

document.write( new Date().toUTCString() );

I ran into the problem of not having set my sources root folder (project window--right click folder, mark directory as > sources root). If you don't set this IDEA doesn't parse the file.

Mine is using LOCATE in mysql:

LOCATE(substr,str), LOCATE(substr,str,pos)

This function is multi-byte safe, and is case-sensitive only if at least one argument is a binary string.

In your case:

mysql_query("
SELECT * FROM `table`
WHERE LOCATE('{$needle}','column') > 0
");

Webkit's support for scrollbars is quite sophisticated. This CSS gives a very minimal scrollbar, with a light grey track and a darker thumb:

::-webkit-scrollbar
{
  width: 12px;  /* for vertical scrollbars */
  height: 12px; /* for horizontal scrollbars */
}

::-webkit-scrollbar-track
{
  background: rgba(0, 0, 0, 0.1);
}

::-webkit-scrollbar-thumb
{
  background: rgba(0, 0, 0, 0.5);
}

This answer is a fantastic source of additional information.

You also can use in this form:

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

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

I think I found a way to do this with the Compile Include=".\Code***.cs" What I wanted is to include code recursively under my Code folder.

Here is the project file sample.

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="15.0" DefaultTargets="BuildTarget">
    <PropertyGroup>
        <OutputType>Library</OutputType>
    </PropertyGroup>
    <PropertyGroup>
        <StartupObject />
    </PropertyGroup>
    <PropertyGroup>
        <RootNamespace>Autogen</RootNamespace>
    </PropertyGroup>
    <ItemGroup>
        <Compile Remove="@(Compile)" />
        <Compile Include=".\Code\**\*.cs" />
    </ItemGroup>
    <Target Name="BuildTarget">
        <Message Text="Build selected" Importance="high"/>
    </Target>
</Project>

You could try something like this:

echo 'maps.google.com' | rev | cut -d'.' -f 1 | rev

Explanation

• rev reverses "maps.google.com" to be moc.elgoog.spam
• cut uses dot (ie '.') as the delimiter, and chooses the first field, which is moc
• lastly, we reverse it again to get com

I liked Marc's answer, but needed the Contains matching to be CaSe InSenSiTiVe.

This was the solution:

bool b = listOfStrings.Any(s => myString.IndexOf(s, StringComparison.OrdinalIgnoreCase) >= 0))

Assign primary key in hibernate

Make sure that the attribute is primary key and Auto Incrementable in the database. Then map it into the data class with the annotation with @GeneratedValue annotation using IDENTITY.

@Entity
@Table(name = "client")
data class Client(
        @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private val id: Int? = null
)

The default tooltip can be edited by using the title attribute

<input type='file' title="your text" />

But if you try to remove this tooltip

<input type='file' title=""/>

This won't work. Here is my little trick to work this, try title with a space. It will work.:)

<input type='file' title=" "/>

If you have a text file with loads of packages you need to add the -r flag

pip install --upgrade --no-deps --force-reinstall -r requirements.txt

$("#myDiv").hide();

will set the css display to none. if you need to set visibility to hidden as well, could do this via

$("#myDiv").css("visibility", "hidden");

or combine both in a chain

$("#myDiv").hide().css("visibility", "hidden");

or write everything with one css() function

$("#myDiv").css({
  display: "none",
  visibility: "hidden"
});

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

#include<stdio.h>
#include<string.h>
main()
{
  int i=0,n;
  int j=0;
  char str[]="        Nar ayan singh              ";
  char *ptr,*ptr1;
  printf("sizeof str:%ld\n",strlen(str));
  while(str[i]==' ')
   {
     memcpy (str,str+1,strlen(str)+1);
   }
  printf("sizeof str:%ld\n",strlen(str));
  n=strlen(str);
  while(str[n]==' ' || str[n]=='\0')
    n--;
  str[n+1]='\0';
  printf("str:%s ",str);
  printf("sizeof str:%ld\n",strlen(str));
}

Try this.

This works even for tables with constraints (foreign key relationships). Alternatively you can just drop the database and recreate, but you may not have the necessary permissions to do that.

mysqldump -u[USERNAME] -p[PASSWORD] \
  --add-drop-table --no-data [DATABASE] | \
  grep -e '^DROP \| FOREIGN_KEY_CHECKS' | \
  mysql -u[USERNAME] -p[PASSWORD] [DATABASE]

In order to overcome foreign key check effects, add show table at the end of the generated script and run many times until the show table command results in an empty set.

There are two ways to fix this:

1. Unix Way (simple and recommended)
2. Homebrew Way

1. Unix Way: In 4 simple steps

1. Execute which git in the terminal to know the location of your git executable. Open that directory & locate gitk inside the bin folder. Copy the path --- typically /usr/local/git/bin
2. Edit your ~/.bash_profile to add the location of local git & gitk in the paths or, simply copy-pasta from the sample written below.

Sample bash_profile:

# enabling gitk
export PATH=/usr/local/git/bin:$PATH

If you don't have a bash_profile want to learn how to create one, then click here.

3. This step is relevant if you're using El Capitan or higher & you run into an unknown color name “lime” error. Locate gitk executable (typically at /usr/local/bin/gitk), take a backup & open it in a text editor. Find all occurences of lime in the file & replace them with "#99FF00".
4. Reload bash: source ~/.bash_profile

Now, run gitk

2. HomeBrew way

Updates - If you do not have homebrew on your mac, get it installed first. It may require sudo privileges.

• brew update
• brew doctor
• brew link git
• added /usr/local/Cellar/git/2.4.0/bin to path & then reload bash & run gitk
• No luck yet? Proceed further.
• Run which git & observe if git is still linked to /usr/bin/git
• If yes, then open the directory & locate the was a binary executable.
• Take its backup, may be save with a name git.bak & delete the original file
• Reload the terminal - source ~/.bash_profile

The url portion of a request (GET and POST) can be limited by both the browser and the server - generally the safe size is 2KB as there are almost no browsers or servers that use a smaller limit.

The body of a request (POST) is normally* limited by the server on a byte size basis in order to prevent a type of DoS attack (note that this means character escaping can increase the byte size of the body). The most common server setting is 10MB, though all popular servers allow this to be increased or decreased via a setting file or panel.

*Some exceptions exist with older cell phone or other small device browsers - in those cases it is more a function of heap space reserved for this purpose on the device then anything else.

If you know the filename, this is an easy way with basic commands:

List all the commits for that file.

git log -- path/to/file

The last commit (topmost) is the one that deleted the file. So you need to restore the second to last commit.

git checkout {second to last commit} -- path/to/file

//It is working
#include<iostream>
using namespace std;
void main()
{
    int a[5];
    int temp=0;
    cout<<"Enter Values"<<endl;
    for(int i=0;i<5;i++)
    {
        cin>>a[i];
    }
    for(int i=0;i<5;i++)
    {
        for(int j=0;j<5;j++)
        {
            if(a[i]>a[j])
            {
                temp=a[i];
                a[i]=a[j];
                a[j]=temp;
            }
        }
    }
    cout<<"Asending Series"<<endl;
    for(int i=0;i<5;i++)
    {
        cout<<endl;
        cout<<a[i]<<endl;
    }


    for(int i=0;i<5;i++)
    {
        for(int j=0;j<5;j++)
        {
            if(a[i]<a[j])
            {
                temp=a[i];
                a[i]=a[j];
                a[j]=temp;
            }
        }
    }
    cout<<"Desnding Series"<<endl;
    for(int i=0;i<5;i++)
    {
        cout<<endl;
        cout<<a[i]<<endl;
    }


}

If you're on Windows, you may find the config file my.ini it in this directory

C:\ProgramData\MySQL\MySQL Server 5.7\

You open this file in a text editor and look for this section:

# The TCP/IP Port the MySQL Server will listen on
port=3306

Then you change the number of the port, save the file. Find the service MYSQL57 under Task Manager > Services and restart it.

import csv

hello = [['Me','You'],['293', '219'],['13','15']]
length = len(hello[0])

with open('test1.csv', 'wb') as testfile:
    csv_writer = csv.writer(testfile)
    for y in range(length):
        csv_writer.writerow([x[y] for x in hello])

will produce an output like this

Me You
293 219
13 15

Hope this helps

The simplest way to handle this case is by using getattr(). You can adapt this example to your needs:

from bs4 import BeautifulSoup

source_html = """
<span class="ratingsDisplay">
    <a class="ratingNumber" href="https://www.youtube.com/watch?v=oHg5SJYRHA0" target="_blank" rel="noopener">
        <span class="ratingsContent">3.7</span>
    </a>
</span>
"""

soup = BeautifulSoup(source_html, "lxml")
my_ratings = getattr(soup.find('span', {"class": "ratingsContent"}), "text", None)
print(my_ratings)

This will find the text element,"3.7", within the tag object <span class="ratingsContent">3.7</span> when it exists, however, default to NoneType when it does not.

getattr(object, name[, default])

Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise, AttributeError is raised.

You can just pass a Date object:
For current date:

$('#calendar').fullCalendar({
    defaultDate: new Date()
});

For specific date '2016-05-20':

$('#calendar').fullCalendar({
    defaultDate: new Date(2016, 4, 20)
});

For my situation, it was a naming conflict problem. Adding $J solves it.

//Old code:
function () {
    var extractionDialog;

    extractionDialog = $j("#extractWindowDialog").dialog({
        autoOpen: false,
        appendTo: "form",
        height: "100",
        width: "250",
        modal: true
    });

    $("extractBomInfoBtn").button().on("click", function () {
        extractionDialog.dialog("open");
    }

And the following is new code.

 $j(function () {
    var extractionDialog;

    extractionDialog = $j("#extractWindowDialog").dialog({
        autoOpen: false,
        appendTo: "form",
        height: "100",
        width: "250",
        modal: true
    });

    $j("extractBomInfoBtn").button().on("click", function () {
        extractionDialog.dialog("open");
    });
});

Hope it could help someone.

I would recommend a Set implementation where the use case is limit to referencing or search for existence and Tuple implementation where the use case requires you to perform iteration. A list is a low-level implementation and requires significant memory overhead.

From this reference:

If you acquire a table lock explicitly with LOCK TABLES, you can request a READ LOCAL lock rather than a READ lock to enable other sessions to perform concurrent inserts while you have the table locked.
