In my case autoPlay not working but autoplay is working fine

I only used this

<script src="plugins/owlcarousel/owl.carousel.js"></script>

no owl.autoplay.js is need it & my owl carousel version is @version 2.0.0

hope this thing help you :)

This only hovers the navbar when you are not on a mobile device, because I find that hovering the navigation does not work well on mobile divices:

    $( document ).ready(function() {

    $( 'ul.nav li.dropdown' ).hover(function() {
        // you could also use this condition: $( window ).width() >= 768
        if ($('.navbar-toggle').css('display') === 'none' 
            && false === ('ontouchstart' in document)) {

            $( '.dropdown-toggle', this ).trigger( 'click' );
        }
    }, function() {
        if ($('.navbar-toggle').css('display') === 'none'
            && false === ('ontouchstart' in document)) {

            $( '.dropdown-toggle', this ).trigger( 'click' );
        }
    });

});

Note for anyone running Vagrant: this can be caused by a bug with their shared folders. Specify NFS for your shared folders in your Vagrantfile to avoid this happening.

Simply adding type: "nfs" to the end will do the trick, like so:

config.vm.synced_folder ".", "/vagrant", type: "nfs"

Just make the property !important in your css file so that background color doesnot change on mouse over.This worked for me.

Example:

.fbColor {
    background-color: #3b5998 !important;
    color: white;
}

If you use the JQuery library you can use the .hover() event which merges the mouseover and mouseout event and helps you with the timing and child elements:

$(this).hover(function(){},function(){});

The first function is the start of the hover and the next is the end. Read more at: http://docs.jquery.com/Events/hover

You are observing this behaviour because your array is not sequential - it has keys 0 and 2, but doesn't have 1 as a key.

Just having numeric indexes isn't enough. json_encode will only encode your PHP array as a JSON array if your PHP array is sequential - that is, if its keys are 0, 1, 2, 3, ...

You can reindex your array sequentially using the array_values function to get the behaviour you want. For example, the code below works successfully in your use case:

echo json_encode(array_values($input)).

Since you have not replied to my comment above, I am posting a solution for both.

You are missing ' in Extended Properties

For Excel 2003 try this (TRIED AND TESTED)

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

BTW, I stopped working with Jet longtime ago. I use ACE now.

        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +

                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

For Excel 2007+

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xlsx" + 
                        ";Extended Properties='Excel 12.0 XML;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.

For example:

Create Table Employee(   
    Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,  
    Emp_SSN Numeric Not Null Unique,  
    Emp_FName varchar(16),   
    Emp_LName varchar(16) 
)

i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.

Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.

Select Distinct Emp_LName
From Employee

You may have many employees with the same last name, but you only want each different last name.

Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.

((ViewGroup) findViewById(android.R.id.content));// you can use this in an Activity to get your layout root view, then pass it to findAllEdittexts() method below.

Here I am iterating only EdiTexts, if you want all Views you can replace EditText with View.

SparseArray<EditText> array = new SparseArray<EditText>();

private void findAllEdittexts(ViewGroup viewGroup) {

    int count = viewGroup.getChildCount();
    for (int i = 0; i < count; i++) {
        View view = viewGroup.getChildAt(i);
        if (view instanceof ViewGroup)
            findAllEdittexts((ViewGroup) view);
        else if (view instanceof EditText) {
            EditText edittext = (EditText) view;
            array.put(editText.getId(), editText);
        }
    }
}

dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )

As others have pointed out, you can also use the equivalent built-in math.hypot():

dist = math.hypot(x2 - x1, y2 - y1)

if not myList:
  print "Nothing here"

You have to create __init__.py on the Models subfolder. The file may be empty. It defines a package.

Then you can do:

from Models.user import User

I have python 2.7.13 and 3.6.2 both installed. Install Anaconda for python 3 first and then you can use conda syntax to get 2.7. My install used: conda create -n py27 python=2.7.13 anaconda

here is the code

    import React, { Component } from 'react';
    import logo from './logo.svg';
    import './image.css';
    import Dropdown from 'react-dropdown';
    import axios from 'axios';

    let obj = {};

    class App extends Component {
      constructor(){
        super();
        this.state = {
          selectedFiles: []
        }
        this.fileUploadHandler = this.fileUploadHandler.bind(this);
      }

      fileUploadHandler(file){
        let selectedFiles_ = this.state.selectedFiles;
        selectedFiles_.push(file);
        this.setState({selectedFiles: selectedFiles_});
      }

      render() {
        let Images = this.state.selectedFiles.map(image => {
          <div className = "image_parent">

              <img src={require(image.src)}
              />
          </div>
        });

        return (
            <div className="image-upload images_main">

            <input type="file" onClick={this.fileUploadHandler}/>

Googling around, the popular answer seems to be "just turn off safe mode":

SET SQL_SAFE_UPDATES = 0;
DELETE FROM instructor WHERE salary BETWEEN 13000 AND 15000;
SET SQL_SAFE_UPDATES = 1;

If I'm honest, I can't say I've ever made a habit of running in safe mode. Still, I'm not entirely comfortable with this answer since it just assumes you should go change your database config every time you run into a problem.

So, your second query is closer to the mark, but hits another problem: MySQL applies a few restrictions to subqueries, and one of them is that you can't modify a table while selecting from it in a subquery.

Quoting from the MySQL manual, Restrictions on Subqueries:

In general, you cannot modify a table and select from the same table in a subquery. For example, this limitation applies to statements of the following forms:

DELETE FROM t WHERE ... (SELECT ... FROM t ...);
UPDATE t ... WHERE col = (SELECT ... FROM t ...);
{INSERT|REPLACE} INTO t (SELECT ... FROM t ...);

Exception: The preceding prohibition does not apply if you are using a subquery for the modified table in the FROM clause. Example:

UPDATE t ... WHERE col = (SELECT * FROM (SELECT ... FROM t...) AS _t ...);

Here the result from the subquery in the FROM clause is stored as a temporary table, so the relevant rows in t have already been selected by the time the update to t takes place.

That last bit is your answer. Select target IDs in a temporary table, then delete by referencing the IDs in that table:

DELETE FROM instructor WHERE id IN (
  SELECT temp.id FROM (
    SELECT id FROM instructor WHERE salary BETWEEN 13000 AND 15000
  ) AS temp
);

I got 500 (but didn't see anything in the browser), until I put

Why not just make the server return the names?

["Woodland Hills", "none", "Los Angeles", "Laguna Hills"]

Then create the <option> elements using JavaScript.

$.ajax({
    url:'suggest.html',
    type:'POST',
    data: 'q=' + str,
    dataType: 'json',
    success: function( json ) {
        $.each(json, function(i, value) {
            $('#myselect').append($('<option>').text(value).attr('value', value));
        });
    }
});

Yet another option uses structs:

struct func_opts {
  int    arg1;
  char * arg2;
  int    arg3;
};

void func(int arg, struct func_opts *opts)
{
    int arg1 = 0, arg3 = 0;
    char *arg2 = "Default";
    if(opts)
      {
        if(opts->arg1)
            arg1 = opts->arg1;
        if(opts->arg2)
            arg2 = opts->arg2;
        if(opts->arg3)
            arg3 = opts->arg3;
      }
    // do stuff
}

// call with defaults
func(3, NULL);

// also call with defaults
struct func_opts opts = {0};
func(3, &opts);

// set some arguments
opts.arg3 = 3;
opts.arg2 = "Yes";
func(3, &opts);

Depends on what you need, you have a couple of choices, you can do:

// this will replace the first occurrence of "www." and return "testwww.com"
"www.testwww.com".replace("www.", "");

// this will slice the first four characters and return "testwww.com"
"www.testwww.com".slice(4);

// this will replace the www. only if it is at the beginning
"www.testwww.com".replace(/^(www\.)/,"");

__all__ is very good - it helps guide import statements without automatically importing modules http://docs.python.org/tutorial/modules.html#importing-from-a-package

using __all__ and import * is redundant, only __all__ is needed

I think one of the most powerful reasons to use import * in an __init__.py to import packages is to be able to refactor a script that has grown into multiple scripts without breaking an existing application. But if you're designing a package from the start. I think it's best to leave __init__.py files empty.

for example:

foo.py - contains classes related to foo such as fooFactory, tallFoo, shortFoo

then the app grows and now it's a whole folder

foo/
    __init__.py
    foofactories.py
    tallFoos.py
    shortfoos.py
    mediumfoos.py
    santaslittlehelperfoo.py
    superawsomefoo.py
    anotherfoo.py

then the init script can say

__all__ = ['foofactories', 'tallFoos', 'shortfoos', 'medumfoos',
           'santaslittlehelperfoo', 'superawsomefoo', 'anotherfoo']
# deprecated to keep older scripts who import this from breaking
from foo.foofactories import fooFactory
from foo.tallfoos import tallFoo
from foo.shortfoos import shortFoo

so that a script written to do the following does not break during the change:

from foo import fooFactory, tallFoo, shortFoo

The size of the numerical types is not defined in the C++ standard, although the minimum sizes are. The way to tell what size they are on your platform is to use numeric limits

For example, the maximum value for a int can be found by:

std::numeric_limits<int>::max();

Computers don't work in base 10, which means that the maximum value will be in the form of 2ⁿ-1 because of how the numbers of represent in memory. Take for example eight bits (1 byte)

  0100 1000

The right most bit (number) when set to 1 represents 2⁰, the next bit 2¹, then 2² and so on until we get to the left most bit which if the number is unsigned represents 2⁷.

So the number represents 2⁶ + 2³ = 64 + 8 = 72, because the 4th bit from the right and the 7th bit right the left are set.

If we set all values to 1:

11111111

The number is now (assuming unsigned)
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255 = 2⁸ - 1
And as we can see, that is the largest possible value that can be represented with 8 bits.

On my machine and int and a long are the same, each able to hold between -2³¹ to 2³¹ - 1. In my experience the most common size on modern 32 bit desktop machine.

int indexOf(Object o) This method returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.

Looking for a one line option:

    <div class="jumbotron bg-dark"> got a team? </div>        

https://getbootstrap.com/docs/4.0/components/jumbotron/

Add the following CSS:

For the parent div:

style="display: flex;"

For child div:

style="align-items: stretch;"

You can access this by

Right click on instance (IE SQLServer2008)
Select "Properties"
Select "Security" option
Change "Server authentication" to "SQL Server and Windows Authentication mode"
Restart the SQLServer service
    Right click on instance
    Click "Restart"

Just for anyone else reading this: This worked for me on 2012 SQL Server too. Thanks

arr.sort(function(a,b) {
    a = a.toLowerCase();
    b = b.toLowerCase();
    if( a == b) return 0;
    if( a > b) return 1;
    return -1;
});

In above function, if we just compare when lower case two value a and b, we will not have the pretty result.

Example, if array is [A, a, B, b, c, C, D, d, e, E] and we use the above function, we have exactly that array. It's not changed anything.

To have the result is [A, a, B, b, C, c, D, d, E, e], we should compare again when two lower case value is equal:

function caseInsensitiveComparator(valueA, valueB) {
    var valueALowerCase = valueA.toLowerCase();
    var valueBLowerCase = valueB.toLowerCase();

    if (valueALowerCase < valueBLowerCase) {
        return -1;
    } else if (valueALowerCase > valueBLowerCase) {
        return 1;
    } else { //valueALowerCase === valueBLowerCase
        if (valueA < valueB) {
            return -1;
        } else if (valueA > valueB) {
            return 1;
        } else {
            return 0;
        }
    }
}

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.

In the Controller, you can use the javax.json to convert and manipulate this.

Download and add the .jar to the project libs and import the JsonObject.

To create an json object, you can use

JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();

To read it from String, you can use

JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();

In PHP, Encryption and Decryption of a string is possible using one of the Cryptography Extensions called OpenSSL function for encrypt and decrypt.

openssl_encrypt() Function: The openssl_encrypt() function is used to encrypt the data.

Syntax is as follows :

string openssl_encrypt( string $data, string $method, string $key, $options = 0, string $iv, string $tag= NULL, string $aad, int $tag_length = 16 )

Parameters are as follows :

$data: It holds the string or data which need to be encrypted.

$method: The cipher method is adopted using openssl_get_cipher_methods() function.

$key: It holds the encryption key.

$options: It holds the bitwise disjunction of the flags OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING.

$iv: It holds the initialization vector which is not NULL.

$tag: It holds the authentication tag which is passed by reference when using AEAD cipher mode (GCM or CCM).

$aad: It holds the additional authentication data.

$tag_length: It holds the length of the authentication tag. The length of authentication tag lies between 4 to 16 for GCM mode.

Return Value: It returns the encrypted string on success or FALSE on failure.

openssl_decrypt() Function The openssl_decrypt() function is used to decrypt the data.

Syntax is as follows :

string openssl_decrypt( string $data, string $method, string $key, int $options = 0, string $iv, string $tag, string $aad)

Parameters are as follows :

$data: It holds the string or data which need to be encrypted.

$method: The cipher method is adopted using openssl_get_cipher_methods() function.

$key: It holds the encryption key.

$options: It holds the bitwise disjunction of the flags OPENSSL_RAW_DATA and OPENSSL_ZERO_PADDING.

$iv: It holds the initialization vector which is not NULL.

$tag: It holds the authentication tag using AEAD cipher mode (GCM or CCM). When authentication fails openssl_decrypt() returns FALSE.

$aad: It holds the additional authentication data.

Return Value: It returns the decrypted string on success or FALSE on failure.

Approach: First declare a string and store it into variable and use openssl_encrypt() function to encrypt the given string and use openssl_decrypt() function to descrypt the given string.

You can find the examples at : https://www.geeksforgeeks.org/how-to-encrypt-and-decrypt-a-php-string/

What you asked for is:

IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
    BEGIN
       DROP TABLE ##CLIENTS_KEYWORD

       CREATE TABLE ##CLIENTS_KEYWORD(client_id int)

    END
ELSE
   CREATE TABLE ##CLIENTS_KEYWORD(client_id int) 

IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
    BEGIN
       DROP TABLE ##TEMP_CLIENTS_KEYWORD

       CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int)

    END
ELSE
   CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int) 

Since you're always going to create the table, regardless of whether the table is deleted or not; a slightly optimised solution is:

IF OBJECT_ID('tempdb..##CLIENTS_KEYWORD') IS NOT NULL
   DROP TABLE ##CLIENTS_KEYWORD

CREATE TABLE ##CLIENTS_KEYWORD(client_id int) 

IF OBJECT_ID('tempdb..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
   DROP TABLE ##TEMP_CLIENTS_KEYWORD

CREATE TABLE ##TEMP_CLIENTS_KEYWORD(client_id int) 

For mine was caused by the imported library project, type something in build.gradle and delete it again and press sync now, the error gone.

I found that AlertifyJS is a better alternative and have a Bootstrap theme.

alertify.alert('Alert Title', 'Alert Message!', function(){ alertify.success('Ok'); });

Also have a 4 components: Alert, Confirm, Prompt and Notifier.

Exmaple: JSFiddle

If your string contains non-ASCII characters - it's better to do it this way: s.toUtf8().data() (or s->toUtf8().data())

If you don't need any features which YAML has and JSON doesn't, I would prefer JSON because it is very simple and is widely supported (has a lot of libraries in many languages). YAML is more complex and has less support. I don't think the parsing speed or memory use will be very much different, and maybe not a big part of your program's performance.

I've assumed a named JSONArray is a JSONObject and accessed the data from the server to populate an Android GridView. For what it is worth my method is:

private String[] fillTable( JSONObject jsonObject ) {
   String[] dummyData = new String[] {"1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7", };
  if( jsonObject != null ) {
      ArrayList<String> data = new ArrayList<String>();
      try {
          // jsonArray looks like { "everything" : [{}, {},] }
          JSONArray jsonArray = jsonObject.getJSONArray( "everything" );
          int number = jsonArray.length(); //How many rows have got from the database?
          Log.i( Constants.INFORMATION, "Number of ows returned:  " + Integer.toString( number ) );
                  // Array elements look like this
          //{"success":1,"error":0,"name":"English One","owner":"Tutor","description":"Initial Alert","posted":"2013-08-09 15:35:40"}
          for( int element = 0; element < number; element++ ) { //visit each element
             JSONObject jsonObject_local = jsonArray.getJSONObject( element );
             //  Overkill on the error/success checking
             Log.e("JSON SUCCESS", Integer.toString( jsonObject_local.getInt(Constants.KEY_SUCCESS) ) );
             Log.e("JSON ERROR", Integer.toString( jsonObject_local.getInt(Constants.KEY_ERROR) ) );
                if ( jsonObject_local.getInt( Constants.KEY_SUCCESS) == Constants.JSON_SUCCESS ) {
                   String name = jsonObject_local.getString( Constants.KEY_NAME );
                   data.add( name );
                   String owner = jsonObject_local.getString( Constants.KEY_OWNER );
                   data.add( owner );
                   String description = jsonObject_local.getString( Constants.KEY_DESCRIPTION );
                   Log.i( "DESCRIPTION", description );
                   data.add( description ); 
                   String date = jsonObject_local.getString( Constants.KEY_DATE );
                   data.add( date );
                }
                else {
                    for( int i = 0; i < 4; i++ ) {
                        data.add( "ERROR" );
                    }
                }
          }
  }  //JSON object is null
  catch ( JSONException jsone) {
      Log.e( "JSON EXCEPTION", jsone.getMessage() );
  }
      dummyData = data.toArray( dummyData );
  }
  return dummyData;

}

We do this kind of XML parsing all the time. The key is defining where the parsing method will leave the reader on exit. If you always leave the reader on the next element following the element that was first read then you can safely and predictably read in the XML stream. So if the reader is currently indexing the <Account> element, after parsing the reader will index the </Accounts> closing tag.

The parsing code looks something like this:

public class Account
{
    string _accountId;
    string _nameOfKin;
    Statements _statmentsAvailable;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read node attributes
        _accountId = reader.GetAttribute( "accountId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                switch( reader.Name )
                {
                    // Read element for a property of this class
                    case "NameOfKin":
                        _nameOfKin = reader.ReadElementContentAsString();
                        break;

                    // Starting sub-list
                case "StatementsAvailable":
                    _statementsAvailable = new Statements();
                    _statementsAvailable.Read( reader );
                    break;

                    default:
                        reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }       
    }
}

The Statements class just reads in the <StatementsAvailable> node

public class Statements
{
    List<Statement> _statements = new List<Statement>();

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();
        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {
            if( reader.IsStartElement() )
            {
                if( reader.Name == "Statement" )
                {
                    var statement = new Statement();
                    statement.ReadFromXml( reader );
                    _statements.Add( statement );               
                }
                else
                {
                    reader.Skip();
                }
            }
            else
            {
                reader.Read();
                break;
            }
        }
    }
}

The Statement class would look very much the same

public class Statement
{
    string _satementId;

    public void ReadFromXml( XmlReader reader )
    {
        reader.MoveToContent();

        // Read noe attributes
        _statementId = reader.GetAttribute( "statementId" );
        ...

        if( reader.IsEmptyElement ) { reader.Read(); return; }

        reader.Read();
        while( ! reader.EOF )
        {           
            ....same basic loop
        }       
    }
}

best answer written by Dmitri Korotkevitch:

Speaking of the installation, SQL Server 2008 allows you to set authentication mode (Windows or SQL Server) during the installation process. You will be forced to choose the strong password for sa user in the case if you choose sql server authentication mode during setup.

If you install SQL Server with Windows Authentication mode and want to change it, you need to do 2 different things:

1. Go to SQL Server Properties/Security tab and change the mode to SQL Server authentication mode

2. Go to security/logins, open SA login properties

a. Uncheck "Enforce password policy" and "Enforce password expiration" check box there if you decide to use weak password

b. Assign password to SA user

c. Open "Status" tab and enable login.

I don't need to mention that every action from above would violate security best practices that recommend to use windows authentication mode, have sa login disabled and use strong passwords especially for sa login.

for flexibility with different formats, use:

$dt = DateTime::createFromFormat('m/d/Y H:i:s', '08/04/2010 22:15:00');
echo $dt->format('g:i A')

Check the php manual for additional format options.

I'm blind, and have been programming for about 13 years on Windows, Mac, Linux and DOS, in languages from C/C++, Python, Java, C# and various smaller languages along the way. Though the original question was around configuring the environment, I think it's best answered by looking at how a blind person would use a computer.

Some people use a talking environment, such as T. V. Raman and the Emacspeak environment mentioned in other answers. The more common solution by far is to have a screen reader which runs in the background monitoring OS activity and alerting the user via synthetic speech or a physical braille display (generally showing somewhere from 20 to 80 characters at a time). This then means a blind person can use any accessible application.

So, I personally use Visual Studio 2008 these days, and run it with very few modifications. I turn off certain features like displaying errors as I type since I find this distracting. Prior to joining Microsoft all my development was done in a standard text editor like Notepad, so once again no customisations.

It is possible to configure a screen reader to announce indentation. I personally don't use this, since Visual Studio takes care of this, and C# uses braces. But this would be very important in a language like Python where whitespace matters. Finally, Emacspeak does make use of different voices/pitches to indicate different parts of syntax (keywords, comments, identifiers, etc).

Connecting to PostgreSQL via SSH Tunneling

In the event that you don't want to open port 5432 to any traffic, or you don't want to configure PostgreSQL to listen to any remote traffic, you can use SSH Tunneling to make a remote connection to the PostgreSQL instance. Here's how:

1. Open PuTTY. If you already have a session set up to connect to the EC2 instance, load that, but don't connect to it just yet. If you don't have such a session, see this post.
2. Go to Connection > SSH > Tunnels
3. Enter 5433 in the Source Port field.
4. Enter 127.0.0.1:5432 in the Destination field.
5. Click the "Add" button.
6. Go back to Session, and save your session, then click "Open" to connect.
7. This opens a terminal window. Once you're connected, you can leave that alone.
8. Open pgAdmin and add a connection.
9. Enter localhost in the Host field and 5433 in the Port field. Specify a Name for the connection, and the username and password. Click OK when you're done.

Here's another way to convert byte[] to long using Java 8 or newer:

private static int bytesToInt(final byte[] bytes, final int offset) {
    assert offset + Integer.BYTES <= bytes.length;

    return (bytes[offset + Integer.BYTES - 1] & 0xFF) |
            (bytes[offset + Integer.BYTES - 2] & 0xFF) << Byte.SIZE |
            (bytes[offset + Integer.BYTES - 3] & 0xFF) << Byte.SIZE * 2 |
            (bytes[offset + Integer.BYTES - 4] & 0xFF) << Byte.SIZE * 3;
}

private static long bytesToLong(final byte[] bytes, final int offset) {
    return toUnsignedLong(bytesToInt(bytes, offset)) << Integer.SIZE |
            toUnsignedLong(bytesToInt(bytes, offset + Integer.BYTES));
}

Converting a long can be expressed as the high- and low-order bits of two integer values subject to a bitwise-OR. Note that the toUnsignedLong is from the Integer class and the first call to toUnsignedLong may be superfluous.

The opposite conversion can be unrolled as well, as others have mentioned.

With React Hook, form is made super easy (React Hook Form: https://github.com/bluebill1049/react-hook-form)

i have reused your html markup.

import React from "react";
import useForm from 'react-hook-form';

function Test() {
  const { useForm, register } = useForm();
  const contactSubmit = data => {
    console.log(data);
  };

  return (
    <form name="contactform" onSubmit={contactSubmit}>
      <div className="col-md-6">
        <fieldset>
          <input name="name" type="text" size="30" placeholder="Name" ref={register} />
          <br />
          <input name="email" type="text" size="30" placeholder="Email" ref={register} />

          </button>
        </fieldset>
      </div>
    </form>
  );
}

You can also do like this:

- command: "{{ item }}"
  args:
    chdir: "/src/package/"
  with_items:
    - "./configure"
    - "/usr/bin/make"
    - "/usr/bin/make install"

Hope that might help other

-Wall and -Werror compiler options can cause it, please check if those are used in compiler settings.

OR you can use pandas:

>>> import pandas as pd
>>> L = [(1,2),(2,3),(4,5),(3,4),(6,7),(6,7),(3,8)]
>>> df=pd.DataFrame(L)
>>> df[1]
0    2
1    3
2    5
3    4
4    7
5    7
6    8
Name: 1, dtype: int64
>>> df[1].tolist()
[2, 3, 5, 4, 7, 7, 8]
>>> 

Or numpy:

>>> import numpy as np
>>> L = [(1,2),(2,3),(4,5),(3,4),(6,7),(6,7),(3,8)]
>>> arr=np.array(L)
>>> arr.T[1]
array([2, 3, 5, 4, 7, 7, 8])
>>> arr.T[1].tolist()
[2, 3, 5, 4, 7, 7, 8]
>>> 

Try this: accumulate function, along with operator add performs the running addition.

import itertools  
import operator  
result = itertools.accumulate([1,2,3,4,5], operator.add)  
list(result)

I had the same issue. Those old files are formatted like a tab-delimited file. I've been able to open my problem files with read_table; ie df = pd.read_table('trouble_maker.xls').

Try this:

$zip = new ZipArchive;
$zip->open('myzip.zip', ZipArchive::CREATE);
foreach (glob("target_folder/*") as $file) {
    $zip->addFile($file);
    if ($file != 'target_folder/important.txt') unlink($file);
}
$zip->close();

This will not zip recursively though.

You are a victim of branch prediction fail.

What is Branch Prediction?

Consider a railroad junction:

_{Image by Mecanismo, via Wikimedia Commons. Used under the CC-By-SA 3.0 license.}

Now for the sake of argument, suppose this is back in the 1800s - before long distance or radio communication.

You are the operator of a junction and you hear a train coming. You have no idea which way it is supposed to go. You stop the train to ask the driver which direction they want. And then you set the switch appropriately.

Trains are heavy and have a lot of inertia. So they take forever to start up and slow down.

Is there a better way? You guess which direction the train will go!

• If you guessed right, it continues on.
• If you guessed wrong, the captain will stop, back up, and yell at you to flip the switch. Then it can restart down the other path.

If you guess right every time, the train will never have to stop.
If you guess wrong too often, the train will spend a lot of time stopping, backing up, and restarting.

Consider an if-statement: At the processor level, it is a branch instruction:

You are a processor and you see a branch. You have no idea which way it will go. What do you do? You halt execution and wait until the previous instructions are complete. Then you continue down the correct path.

Modern processors are complicated and have long pipelines. So they take forever to "warm up" and "slow down".

Is there a better way? You guess which direction the branch will go!

• If you guessed right, you continue executing.
• If you guessed wrong, you need to flush the pipeline and roll back to the branch. Then you can restart down the other path.

If you guess right every time, the execution will never have to stop.
If you guess wrong too often, you spend a lot of time stalling, rolling back, and restarting.

This is branch prediction. I admit it's not the best analogy since the train could just signal the direction with a flag. But in computers, the processor doesn't know which direction a branch will go until the last moment.

So how would you strategically guess to minimize the number of times that the train must back up and go down the other path? You look at the past history! If the train goes left 99% of the time, then you guess left. If it alternates, then you alternate your guesses. If it goes one way every three times, you guess the same...

In other words, you try to identify a pattern and follow it. This is more or less how branch predictors work.

Most applications have well-behaved branches. So modern branch predictors will typically achieve >90% hit rates. But when faced with unpredictable branches with no recognizable patterns, branch predictors are virtually useless.

Further reading: "Branch predictor" article on Wikipedia.

As hinted from above, the culprit is this if-statement:

if (data[c] >= 128)
    sum += data[c];

Notice that the data is evenly distributed between 0 and 255. When the data is sorted, roughly the first half of the iterations will not enter the if-statement. After that, they will all enter the if-statement.

This is very friendly to the branch predictor since the branch consecutively goes the same direction many times. Even a simple saturating counter will correctly predict the branch except for the few iterations after it switches direction.

Quick visualization:

T = branch taken
N = branch not taken

data[] = 0, 1, 2, 3, 4, ... 126, 127, 128, 129, 130, ... 250, 251, 252, ...
branch = N  N  N  N  N  ...   N    N    T    T    T  ...   T    T    T  ...

       = NNNNNNNNNNNN ... NNNNNNNTTTTTTTTT ... TTTTTTTTTT  (easy to predict)

However, when the data is completely random, the branch predictor is rendered useless, because it can't predict random data. Thus there will probably be around 50% misprediction (no better than random guessing).

data[] = 226, 185, 125, 158, 198, 144, 217, 79, 202, 118,  14, 150, 177, 182, ...
branch =   T,   T,   N,   T,   T,   T,   T,  N,   T,   N,   N,   T,   T,   T  ...

       = TTNTTTTNTNNTTT ...   (completely random - impossible to predict)

So what can be done?

If the compiler isn't able to optimize the branch into a conditional move, you can try some hacks if you are willing to sacrifice readability for performance.

Replace:

if (data[c] >= 128)
    sum += data[c];

with:

int t = (data[c] - 128) >> 31;
sum += ~t & data[c];

This eliminates the branch and replaces it with some bitwise operations.

_{(Note that this hack is not strictly equivalent to the original if-statement. But in this case, it's valid for all the input values of data[].)}

Benchmarks: Core i7 920 @ 3.5 GHz

C++ - Visual Studio 2010 - x64 Release

Java - NetBeans 7.1.1 JDK 7 - x64

Observations:

• With the Branch: There is a huge difference between the sorted and unsorted data.
• With the Hack: There is no difference between sorted and unsorted data.
• In the C++ case, the hack is actually a tad slower than with the branch when the data is sorted.

A general rule of thumb is to avoid data-dependent branching in critical loops (such as in this example).

Update:

• GCC 4.6.1 with -O3 or -ftree-vectorize on x64 is able to generate a conditional move. So there is no difference between the sorted and unsorted data - both are fast.

  (Or somewhat fast: for the already-sorted case, cmov can be slower especially if GCC puts it on the critical path instead of just add, especially on Intel before Broadwell where cmov has 2 cycle latency: gcc optimization flag -O3 makes code slower than -O2)

• VC++ 2010 is unable to generate conditional moves for this branch even under /Ox.

• Intel C++ Compiler (ICC) 11 does something miraculous. It interchanges the two loops, thereby hoisting the unpredictable branch to the outer loop. So not only is it immune to the mispredictions, it is also twice as fast as whatever VC++ and GCC can generate! In other words, ICC took advantage of the test-loop to defeat the benchmark...

• If you give the Intel compiler the branchless code, it just out-right vectorizes it... and is just as fast as with the branch (with the loop interchange).

This goes to show that even mature modern compilers can vary wildly in their ability to optimize code...

Here is a wget script in Python:

# From python cookbook, 2nd edition, page 487
import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print

What you need is nm and its -D option:

$ nm -D /usr/lib/libopenal.so.1
.
.
.
00012ea0 T alcSetThreadContext
000140f0 T alcSuspendContext
         U atanf
         U calloc
.
.
.

Exported sumbols are indicated by a T. Required symbols that must be loaded from other shared objects have a U. Note that the symbol table does not include just functions, but exported variables as well.

See the nm manual page for more information.

The code above exports data without the heading columns which is weird. Here's how to do it. You have to merge the two files later though using text a editor.

SELECT column_name FROM information_schema.columns WHERE table_schema = 'my_app_db' AND table_name = 'customers' INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/customers_heading_cols.csv' FIELDS TERMINATED BY '' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY ',';

Use a resize sensor from the css-element-queries library:

https://github.com/marcj/css-element-queries

new ResizeSensor(jQuery('#myElement'), function() {
    console.log('myelement has been resized');
});

It uses a event based approach and doesn't waste your cpu time. Works in all browsers incl. IE7+.

well distinct can be slower than group by on some occasions in postgres (dont know about other dbs).

tested example:

postgres=# select count(*) from (select distinct i from g) a;

count 

10001
(1 row)

Time: 1563,109 ms

postgres=# select count(*) from (select i from g group by i) a;

count
10001
(1 row)

Time: 594,481 ms

so be careful ... :)

One way to do that would be to upload your script on Colab and download it in .py format from File -> Download .py

I ran into the same situation where when I copied the formula to another cell the formula was still referencing the cell used in the first formula. To correct this when you set up the rules, select the option "use a formula to determine which cells to format. Then type in the box your formula, for example H23*.25. When you copy the cells down the formulas will change to H24*.25, H25*.25 and so on. Hope this helps.

EDIT (26/08/2017): The solution below works well with Angular2 and 4. I've updated it to contain a template variable and click handler and tested it with Angular 4.3.
For Angular4, ngComponentOutlet as described in Ophir's answer is a much better solution. But right now it does not support inputs & outputs yet. If [this PR](https://github.com/angular/angular/pull/15362] is accepted, it would be possible through the component instance returned by the create event.
ng-dynamic-component may be the best and simplest solution altogether, but I haven't tested that yet.

@Long Field's answer is spot on! Here's another (synchronous) example:

import {Compiler, Component, NgModule, OnInit, ViewChild,
  ViewContainerRef} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

@Component({
  selector: 'my-app',
  template: `<h1>Dynamic template:</h1>
             <div #container></div>`
})
export class App implements OnInit {
  @ViewChild('container', { read: ViewContainerRef }) container: ViewContainerRef;

  constructor(private compiler: Compiler) {}

  ngOnInit() {
    this.addComponent(
      `<h4 (click)="increaseCounter()">
        Click to increase: {{counter}}
      `enter code here` </h4>`,
      {
        counter: 1,
        increaseCounter: function () {
          this.counter++;
        }
      }
    );
  }

  private addComponent(template: string, properties?: any = {}) {
    @Component({template})
    class TemplateComponent {}

    @NgModule({declarations: [TemplateComponent]})
    class TemplateModule {}

    const mod = this.compiler.compileModuleAndAllComponentsSync(TemplateModule);
    const factory = mod.componentFactories.find((comp) =>
      comp.componentType === TemplateComponent
    );
    const component = this.container.createComponent(factory);
    Object.assign(component.instance, properties);
    // If properties are changed at a later stage, the change detection
    // may need to be triggered manually:
    // component.changeDetectorRef.detectChanges();
  }
}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

If @myInt is zero it means no rows in the table: it would be NULL if never set at all.

COUNT will always return a row, even for no rows in a table.

Edit, Apr 2012: the rules for this are described in my answer here:Does COUNT(*) always return a result?

Your count/assign is correct but could be either way:

select @myInt = COUNT(*) from myTable
set @myInt = (select COUNT(*) from myTable)

However, if you are just looking for the existence of rows, (NOT) EXISTS is more efficient:

IF NOT EXISTS (SELECT * FROM myTable)

Taking what I feel are the best aspects of the previous examples, here's what I came up with:

class Struct:
  '''The recursive class for building and representing objects with.'''
  def __init__(self, obj):
    for k, v in obj.iteritems():
      if isinstance(v, dict):
        setattr(self, k, Struct(v))
      else:
        setattr(self, k, v)
  def __getitem__(self, val):
    return self.__dict__[val]
  def __repr__(self):
    return '{%s}' % str(', '.join('%s : %s' % (k, repr(v)) for
      (k, v) in self.__dict__.iteritems()))

Instead of String you are trying to get custom POJO object details as output by calling another API/URI, try the this solution. I hope it will be clear and helpful for how to use RestTemplate also,

In Spring Boot, first we need to create Bean for RestTemplate under the @Configuration annotated class. You can even write a separate class and annotate with @Configuration like below.

@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
       return builder.build();
    }
}

Then, you have to define RestTemplate with @Autowired or @Injected under your service/Controller, whereever you are trying to use RestTemplate. Use the below code,

@Autowired
private RestTemplate restTemplate;

Now, will see the part of how to call another api from my application using above created RestTemplate. For this we can use multiple methods like execute(), getForEntity(), getForObject() and etc. Here I am placing the code with example of execute(). I have even tried other two, I faced problem of converting returned LinkedHashMap into expected POJO object. The below, execute() method solved my problem.

ResponseEntity<List<POJO>> responseEntity = restTemplate.exchange(
    URL, 
    HttpMethod.GET, 
    null, 
    new ParameterizedTypeReference<List<POJO>>() {
    });
List<POJO> pojoObjList = responseEntity.getBody();

Happy Coding :)

use the command below

python -m pip install mysql-connector 

From the docs:

"a UNIQUE index permits multiple NULL values for columns that can contain NULL"

This applies to all engines but BDB.

A simple AJAX call to your server, and then the serverside logic to get the ip address should do the trick.

$.getJSON('getip.php', function(data){
  alert('Your ip is: ' +  data.ip);
});

Then in php you might do:

<?php
/* getip.php */
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');

if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
  $ip=$_SERVER['HTTP_CLIENT_IP'];
}

Here's a relatively easy method to do this. Throw a GridView into your layout, setting the stretch mode to stretch the column widths, set the spacing to 0 (or whatever you want), and set the number of columns to 2:

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:verticalSpacing="0dp"
        android:horizontalSpacing="0dp"
        android:stretchMode="columnWidth"
        android:numColumns="2"/>

</FrameLayout>

Make a custom ImageView that maintains its aspect ratio:

src/com/example/graphicstest/SquareImageView.java

public class SquareImageView extends ImageView {
    public SquareImageView(Context context) {
        super(context);
    }

    public SquareImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SquareImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
    }
}

Make a layout for a grid item using this SquareImageView and set the scaleType to centerCrop:

res/layout/grid_item.xml

<?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

    <com.example.graphicstest.SquareImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"/>

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"
        android:layout_gravity="bottom"
        android:textColor="@android:color/white"
        android:background="#55000000"/>

</FrameLayout>

Now make some sort of adapter for your GridView:

src/com/example/graphicstest/MyAdapter.java

private final class MyAdapter extends BaseAdapter {
    private final List<Item> mItems = new ArrayList<Item>();
    private final LayoutInflater mInflater;

    public MyAdapter(Context context) {
        mInflater = LayoutInflater.from(context);

        mItems.add(new Item("Red",       R.drawable.red));
        mItems.add(new Item("Magenta",   R.drawable.magenta));
        mItems.add(new Item("Dark Gray", R.drawable.dark_gray));
        mItems.add(new Item("Gray",      R.drawable.gray));
        mItems.add(new Item("Green",     R.drawable.green));
        mItems.add(new Item("Cyan",      R.drawable.cyan));
    }

    @Override
    public int getCount() {
        return mItems.size();
    }

    @Override
    public Item getItem(int i) {
        return mItems.get(i);
    }

    @Override
    public long getItemId(int i) {
        return mItems.get(i).drawableId;
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        View v = view;
        ImageView picture;
        TextView name;

        if (v == null) {
            v = mInflater.inflate(R.layout.grid_item, viewGroup, false);
            v.setTag(R.id.picture, v.findViewById(R.id.picture));
            v.setTag(R.id.text, v.findViewById(R.id.text));
        }

        picture = (ImageView) v.getTag(R.id.picture);
        name = (TextView) v.getTag(R.id.text);

        Item item = getItem(i);

        picture.setImageResource(item.drawableId);
        name.setText(item.name);

        return v;
    }

    private static class Item {
        public final String name;
        public final int drawableId;

        Item(String name, int drawableId) {
            this.name = name;
            this.drawableId = drawableId;
        }
    }
}

Set that adapter to your GridView:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    GridView gridView = (GridView)findViewById(R.id.gridview);
    gridView.setAdapter(new MyAdapter(this));
}

And enjoy the results:

# Pygame Example  

import pygame, sys  
from pygame.locals import *

pygame.init()  
DISPLAYSURF = pygame.display.set_mode((400, 300))  
pygame.display.set_caption('IBM Emulator')

BLACK = (0, 0, 0)  
GREEN = (0, 255, 0)

fontObj = pygame.font.Font('freesansbold.ttf', 32)  
textSurfaceObj = fontObj.render('IBM PC Emulator', True, GREEN,BLACK)  
textRectObj = textSurfaceObj.get_rect()  
textRectObj = (10, 10)

try:  
    while True: # main loop  
        DISPLAYSURF.fill(BLACK)  
        DISPLAYSURF.blit(textSurfaceObj, textRectObj)  
        for event in pygame.event.get():  
            if event.type == QUIT:  
                pygame.quit()  
                sys.exit()  
        pygame.display.update()  
except SystemExit:  
    pass

You can use a global variable within other functions by declaring it as global within each function that assigns a value to it:

globvar = 0

def set_globvar_to_one():
    global globvar    # Needed to modify global copy of globvar
    globvar = 1

def print_globvar():
    print(globvar)     # No need for global declaration to read value of globvar

set_globvar_to_one()
print_globvar()       # Prints 1

I imagine the reason for it is that, since global variables are so dangerous, Python wants to make sure that you really know that's what you're playing with by explicitly requiring the global keyword.

See other answers if you want to share a global variable across modules.

There are MYSQL functions you can use. Like this one that resolves the user:

SELECT USER();

This will return something like root@localhost so you get the host and the user.

To get the current database run this statement:

SELECT DATABASE();

Other useful functions can be found here: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Angular 4+: Use renderer.selectRootElement with a CSS selector to access the element.

I've got a form that initially displays an email input. After the email is entered, the form will be expanded to allow them to continue adding information relating to their project. However, if they are not an existing client, the form will include an address section above the project information section.

As of now, the data entry portion has not been broken up into components, so the sections are managed with *ngIf directives. I need to set focus on the project notes field if they are an existing client, or the first name field if they are new.

I tried the solutions with no success. However, Update 3 in this answer gave me half of the eventual solution. The other half came from MatteoNY's response in this thread. The result is this:

import { NgZone, Renderer } from '@angular/core';

constructor(private ngZone: NgZone, private renderer: Renderer) {}

setFocus(selector: string): void {
    this.ngZone.runOutsideAngular(() => {
        setTimeout(() => {
            this.renderer.selectRootElement(selector).focus();
        }, 0);
    });
}

submitEmail(email: string): void {
    // Verify existence of customer
    ...
    if (this.newCustomer) {
        this.setFocus('#firstname');
    } else {
        this.setFocus('#description');
    }
}

Since the only thing I'm doing is setting the focus on an element, I don't need to concern myself with change detection, so I can actually run the call to renderer.selectRootElement outside of Angular. Because I need to give the new sections time to render, the element section is wrapped in a timeout to allow the rendering threads time to catch up before the element selection is attempted. Once all that is setup, I can simply call the element using basic CSS selectors.

I know this example dealt primarily with the focus event, but it's hard for me that this couldn't be used in other contexts.

UPDATE: Angular dropped support for Renderer in Angular 4 and removed it completely in Angular 9. This solution should not be impacted by the migration to Renderer2. Please refer to this link for additional information: Renderer migration to Renderer2

Essentially, PHPStorm = WebStorm + PHP, SQL and more.

BUT (and this is a very important "but") because it is capable of parsing so much more, it quite often fails to parse Node.js dependencies, as they (probably) conflict with some other syntax it is capable of parsing.

The most notable example of that would be Mongoose model definition, where WebStorm easily recognizes mongoose.model method, whereas PHPStorm marks it as unresolved as soon as you connect Node.js plugin.

Surprisingly, it manages to resolve the method if you turn the plugin off, but leave the core modules connected, but then it cannot be used for debugging. And this happens to quite a few methods out there.

All this goes for PHPStorm 8.0.1, maybe in later releases this annoying bug would be fixed.

I got this problem on freeBSD. It seems lapack packages are missing, I solved it installing them (as root) with:

pkg install lapack
pkg install atlas-devel  #not sure this is needed, but just in case

I imagine it could work on other system too using the appropriate package installer (e.g. apt-get)

I do it like Bradley Braithwaite suggests in his blog:

app
    .factory('searchService', ['$q', '$http', function($q, $http) {
        var service = {};

        service.search = function search(query) {
            // We make use of Angular's $q library to create the deferred instance
            var deferred = $q.defer();

            $http
                .get('http://localhost/v1?=q' + query)
                .success(function(data) {
                    // The promise is resolved once the HTTP call is successful.
                    deferred.resolve(data);
                })
                .error(function(reason) {
                    // The promise is rejected if there is an error with the HTTP call.
                    deferred.reject(reason);
                });

            // The promise is returned to the caller
            return deferred.promise;
        };

        return service;
    }])
    .controller('SearchController', ['$scope', 'searchService', function($scope, searchService) {
        // The search service returns a promise API
        searchService
            .search($scope.query)
            .then(function(data) {
                // This is set when the promise is resolved.
                $scope.results = data;
            })
            .catch(function(reason) {
                // This is set in the event of an error.
                $scope.error = 'There has been an error: ' + reason;
            });
    }])

Key Points:

• The resolve function links to the .then function in our controller i.e. all is well, so we can keep our promise and resolve it.

• The reject function links to the .catch function in our controller i.e. something went wrong, so we can’t keep our promise and need to reject it.

It is quite stable and safe and if you have other conditions to reject the promise you can always filter your data in the success function and call deferred.reject(anotherReason) with the reason of the rejection.

As Ryan Vice suggested in the comments, this may not be seen as useful unless you fiddle a bit with the response, so to speak.

Because success and error are deprecated since 1.4 maybe it is better to use the regular promise methods then and catch and transform the response within those methods and return the promise of that transformed response.

I am showing the same example with both approaches and a third in-between approach:

success and error approach (success and error return a promise of an HTTP response, so we need the help of $q to return a promise of data):

function search(query) {
  // We make use of Angular's $q library to create the deferred instance
  var deferred = $q.defer();

  $http.get('http://localhost/v1?=q' + query)
  .success(function(data,status) {
    // The promise is resolved once the HTTP call is successful.
    deferred.resolve(data);              
  })

  .error(function(reason,status) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.error){
      deferred.reject({text:reason.error, status:status});
    }else{
      //if we don't get any answers the proxy/api will probably be down
      deferred.reject({text:'whatever', status:500});
    }
  });

  // The promise is returned to the caller
  return deferred.promise;
};

then and catch approach (this is a bit more difficult to test, because of the throw):

function search(query) {

  var promise=$http.get('http://localhost/v1?=q' + query)

  .then(function (response) {
    // The promise is resolved once the HTTP call is successful.
    return response.data;
  },function(reason) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.statusText){
      throw reason;
    }else{
      //if we don't get any answers the proxy/api will probably be down
      throw {statusText:'Call error', status:500};
    }

  });

  return promise;
}

There is a halfway solution though (this way you can avoid the throw and anyway you'll probably need to use $q to mock the promise behavior in your tests):

function search(query) {
  // We make use of Angular's $q library to create the deferred instance
  var deferred = $q.defer();

  $http.get('http://localhost/v1?=q' + query)

  .then(function (response) {
    // The promise is resolved once the HTTP call is successful.
    deferred.resolve(response.data);
  },function(reason) {
    // The promise is rejected if there is an error with the HTTP call.
    if(reason.statusText){
      deferred.reject(reason);
    }else{
      //if we don't get any answers the proxy/api will probably be down
      deferred.reject({statusText:'Call error', status:500});
    }

  });

  // The promise is returned to the caller
  return deferred.promise;
}

Any kind of comments or corrections are welcome.

You need to change your code to the following:

@RestController
public class IndexController implements ErrorController{

    private static final String PATH = "/error";

    @RequestMapping(value = PATH)
    public String error() {
        return "Error handling";
    }

    @Override
    public String getErrorPath() {
        return PATH;
    }
}

Your code did not work, because Spring Boot automatically registers the BasicErrorController as a Spring Bean when you have not specified an implementation of ErrorController.

To see that fact just navigate to ErrorMvcAutoConfiguration.basicErrorController here.

Try this code

HashMap<String, String> map = new HashMap<String, String>();
map.put("EmpID", EmpID);
map.put("UnChecked", "1");

import pandas as pd
df = pd.DataFrame([{'Product': 'Coke', 'Prices': [100,123,101,105,99,94,98]},{'Product': 'Pepsi', 'Prices': [101,104,104,101,99,99,99]}])
print(df)
df = df.assign(Prices=df.Prices.str.split(',')).explode('Prices')
print(df)

Try this in pandas >=0.25 version

Select all of the packages that are not up to date and update them.

Use the following:

type file.txt | findstr /v ERROR | findstr /v REFERENCE

This has the advantage of using standard tools in the Windows OS, rather than having to find and install sed/awk/perl and such.

See the following transcript for it in operation:

C:\>type file.txt
Good Line of data
bad line of C:\Directory\ERROR\myFile.dll
Another good line of data
bad line: REFERENCE
Good line

C:\>type file.txt | findstr /v ERROR | findstr /v REFERENCE
Good Line of data
Another good line of data
Good line

• Left mouse click on the bulb of error line
• Click Edit Include path
• Then this window popup

• Just set Compiler path

Not sure if it's what you mean, but you can do this:

plot(1:10, xaxt = "n", xlab='Some Letters')
axis(1, at=1:10, labels=letters[1:10])

which then gives you the graph:

If you want to obfuscate, use this:

System.out.println( 1 & Boolean.hashCode( true ) >> 1 );  // 1
System.out.println( 1 & Boolean.hashCode( false ) >> 1 ); // 0

Maybe wrong path..? Check your .classpath file.

Another option is to add it to the jest.config.js file after the module.exports definition:

process.env = Object.assign(process.env, {
  VAR_NAME: 'varValue',
  VAR_NAME_2: 'varValue2'
});

This way it's not necessary to define the environment variables in each .spec file and they can be adjusted globally.

If you have a preference for Java 8 streams as your coding style then this can be achieved using just JDK primitives.

String hex = "0001027f80fdfeff";

byte[] converted = IntStream.range(0, hex.length() / 2)
    .map(i -> Character.digit(hex.charAt(i * 2), 16) << 4 | Character.digit(hex.charAt((i * 2) + 1), 16))
    .collect(ByteArrayOutputStream::new,
             ByteArrayOutputStream::write,
             (s1, s2) -> s1.write(s2.toByteArray(), 0, s2.size()))
    .toByteArray();

The , 0, s2.size() parameters in the collector concatenate function can be omitted if you don't mind catching IOException.

Took me a while to find this but note that if you have a spacing error you will also get the same error:

[: =: unary operator expected

Correct:

if [ "$APP_ENV" = "staging" ]

vs

if ["$APP_ENV" = "staging" ]

As always setting -x debug variable helps to find these:

set -x

if you want to do very quick plots with secondary Y-Axis then there is much easier way using Pandas wrapper function and just 2 lines of code. Just plot your first column then plot the second but with parameter secondary_y=True, like this:

df.A.plot(label="Points", legend=True)
df.B.plot(secondary_y=True, label="Comments", legend=True)

This would look something like below:

You can do few more things as well. Take a look at Pandas plotting doc.

This is usually caused by duplicates in the query specified in USING clause. This probably means that TABLE_A is a parent table and the same ROWID is returned several times.

You could quickly solve the problem by using a DISTINCT in your query (in fact, if 'Y' is a constant value you don't even need to put it in the query).

Assuming your query is correct (don't know your tables) you could do something like this:

  MERGE INTO table_1 a
      USING 
      (SELECT distinct ta.ROWID row_id
              FROM table_1 a ,table_2 b ,table_3 c
              WHERE a.mbr = c.mbr
              AND b.head = c.head
              AND b.type_of_action <> '6') src
              ON ( a.ROWID = src.row_id )
  WHEN MATCHED THEN UPDATE SET in_correct = 'Y';

I find another way of doing the same thing by using @PathParam. Here is the code sample.

@GET
@Path("data/xml/{Ids}")
@Produces("application/xml")
public Object getData(@PathParam("zrssIds") String Ids)
{
  System.out.println("zrssIds = " + Ids);
  //Here you need to use String tokenizer to make the array from the string.
}

Call the service by using following url.

http://localhost:8080/MyServices/resources/cm/data/xml/12,13,56,76

where

http://localhost:8080/[War File Name]/[Servlet Mapping]/[Class Path]/data/xml/12,13,56,76

the chsh program will let you change your default shell. It will want the full path to the executable, so if your shell is fish then it will want you to provide the output given when you type which fish.

You'll see a line starting with "Shell:". If you've never edited it, it most likely says "Shell: /bin/bash". Replace that /bin/bash path with the path to your desired shell.

tomcat is designed as JSP servlet container. Apache is designed PHP web server. Use apache as web server, responding for PHP request, and direct JSP servlet request to tomcat container. should be better implementation.

you can use if statement like below

select CONCAT(if(affiliate_name is null ,'',affiliate_name),'- ',if(model is null ,'',affiliate_name)) as model from devices

Depending on your exact requirements, you may do best with a jagged array of sorts with:

List<string>[] results = new { new List<string>(), new List<string>() };

Or you may do well with a list of lists or some other such construct.

const should have been the default in C++. Like this :

int i = 5 ; // i is a constant

var int i = 5 ; // i is a real variable

Like Vito mentions, this error occurs after Java updates as the path:

C:\ProgramData\Oracle\Java\javapath

is added to the Path environment variable, causing Eclipse to run using the wrong java version.

To fix the problem:

1) Right-click on Computer and choose Properties.

2) Click Advanced system settings

3) Click Environment Variables...

4) Find the Path variable in the System variables section.

5) Choose it and click Edit...

6) Find and delete the above mentioned path.

This fixed it for me. I should mention that I already have the path:

c:\Program Files\Java\jdk1.7.0_21\bin

in the Path variable, but the new path was added to the beginning of the Path variable and therefore resolution would use that path first.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

You can access the fields by indexing the object array:

foreach (object[] item in selectedValues)
{
  idTextBox.Text = item[0];
  titleTextBox.Text = item[1];
  contentTextBox.Text = item[2];
}

That said, you'd be better off storing the fields in a small class of your own if the number of items is not dynamic:

public class MyObject
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Content { get; set; }
}

Then you can do:

foreach (MyObject item in selectedValues)
{
  idTextBox.Text = item.Id;
  titleTextBox.Text = item.Title;
  contentTextBox.Text = item.Content;
}

( find YOURDIR -type d | sort -r;
  find yourdir -type f ) |
grep -v /CVS | grep -v /SVN |
while read f; do mv -v $f `echo $f | tr '[A-Z]' '[a-z]'`; done

First rename the directories bottom up sort -r (where -depth is not available), then the files. Then grep -v /CVS instead of find ...-prune because it's simpler. For large directories, for f in ... can overflow some shell buffers. Use find ... | while read to avoid that.

And yes, this will clobber files which differ only in case...

No matter what $action is, it will always either not be "add" OR not be "delete", which is why the if condition always passes. What you want is to use && instead of ||:

(!isset($action)) || ($action !="add" && $action !="delete"))

One thing I see here to optimize.

While I do agree that the balls hit when the distance is the sum of their radii one should never actually calculate this distance! Rather, calculate it's square and work with it that way. There's no reason for that expensive square root operation.

Also, once you have found a collision you have to continue to evaluate collisions until no more remain. The problem is that the first one might cause others that have to be resolved before you get an accurate picture. Consider what happens if the ball hits a ball at the edge? The second ball hits the edge and immediately rebounds into the first ball. If you bang into a pile of balls in the corner you could have quite a few collisions that have to be resolved before you can iterate the next cycle.

As for the O(n^2), all you can do is minimize the cost of rejecting ones that miss:

1) A ball that is not moving can't hit anything. If there are a reasonable number of balls lying around on the floor this could save a lot of tests. (Note that you must still check if something hit the stationary ball.)

2) Something that might be worth doing: Divide the screen into a number of zones but the lines should be fuzzy--balls at the edge of a zone are listed as being in all the relevant (could be 4) zones. I would use a 4x4 grid, store the zones as bits. If an AND of the zones of two balls zones returns zero, end of test.

3) As I mentioned, don't do the square root.

I'm using Eclipse Classic 3.7.1.

The solution is: Window > Preferences > General > Editors > Sctructured Text Editors > Task Tags and checking "Enable searching for Task Tags" checkbox.

I fear this might turn out to BE the long way round but could depend on how big your data set is – presumably more than four months for example.

Assuming your data is in ColumnA:C and has column labels in Row 1, also that Month is formatted mmm(this last for ease of sorting):

1. Sort the data by Name then Month
2. Enter in D2 =IF(AND(A2=A1,C2=C1),D1+1,1) (One way to deal with what is the tricky issue of multiple entries for the same person for the same month).
3. Create a pivot table from A1:D(last occupied row no.)
4. Say insert in F1.
5. Layout as in screenshot.

I’m hoping this would be adequate for your needs because pivot table should automatically update (provided range is appropriate) in response to additional data with refresh. If not (you hard taskmaster), continue but beware that the following steps would need to be repeated each time the source data changes.

5. Copy pivot table and Paste Special/Values to, say, L1.
6. Delete top row of copied range with shift cells up.
7. Insert new cell at L1 and shift down.
8. Key 'Name' into L1.
9. Filter copied range and for ColumnL, select Row Labels and numeric values.
10. Delete contents of L2:L(last selected cell)
11. Delete blank rows in copied range with shift cells up (may best via adding a column that counts all 12 months). Hopefully result should be as highlighted in yellow.

Happy to explain further/try again (I've not really tested this) if does not suit.

EDIT (To avoid second block of steps above and facilitate updating for source data changes)

.0. Before first step 2. add a blank row at the very top and move A2:D2 up.
.2. Adjust cell references accordingly (in D3 =IF(AND(A3=A2,C3=C2),D2+1,1).
.3. Create pivot table from A:D

.6. Overwrite Row Labels with Name.
.7. PivotTable Tools, Design, Report Layout, Show in Tabular Form and sort rows and columns A>Z.
.8. Hide Row1, ColumnG and rows and columns that show (blank).

Steps .0. and .2. in the edit are not required if the pivot table is in a different sheet from the source data (recommended).

Step .3. in the edit is a change to simplify the consequences of expanding the source data set. However introduces (blank) into pivot table that if to be hidden may need adjustment on refresh. So may be better to adjust source data range each time that changes instead: PivotTable Tools, Options, Change Data Source, Change Data Source, Select a table or range). In which case copy rather than move in .0.

The function match works on vectors:

x <- sample(1:10)
x
# [1]  4  5  9  3  8  1  6 10  7  2
match(c(4,8),x)
# [1] 1 5

match only returns the first encounter of a match, as you requested. It returns the position in the second argument of the values in the first argument.

For multiple matching, %in% is the way to go:

x <- sample(1:4,10,replace=TRUE)
x
# [1] 3 4 3 3 2 3 1 1 2 2
which(x %in% c(2,4))
# [1]  2  5  9 10

%in% returns a logical vector as long as the first argument, with a TRUE if that value can be found in the second argument and a FALSE otherwise.

The ld returned 1 exit status error is the consequence of previous errors. In your example there is an earlier error - undefined reference to 'clrscr' - and this is the real one. The exit status error just signals that the linking step in the build process encountered some errors. Normally exit status 0 means success, and exit status > 0 means errors.

When you build your program, multiple tools may be run as separate steps to create the final executable. In your case one of those tools is ld, which first reports the error it found (clrscr reference missing), and then it returns the exit status. Since the exit status is > 0, it means an error and is reported.

In many cases tools return as the exit status the number of errors they encountered. So if ld tool finds two errors, its exit status would be 2.

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

Use the @RequestParam to pass a parameter to the controller handler method. In the jsp your form should have an input field with name = "id" like the following:

<input type="text" name="id" />
<input type="submit" />

Then in your controller, your handler method should be like the following:

@RequestMapping("listNotes")
public String listNotes(@RequestParam("id") int id) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes", this.notesService.listNotesBySectionId(id, person));
    return "note";
}

I'm using Xcode 8.1 (8B62) with a deployment target set to 10.1 and I haven't had much luck with the override options mentioned above. However checking the "Hide status bar" option in Deployment Info did the trick for me.

I hope this helps.

As you can see here, when you have more values there is a better approach.

http://jsfiddle.net/MsYGJ/

temp = {}
// Store each of the elements in an object keyed of of the name field.  If there is a collision (the name already exists) then it is just replaced with the most recent one.
for (var i = 0; i < varjson.DATA.length; i++) {
    temp[varjson.DATA[i].name] = varjson.DATA[i];
}
// Reset the array in varjson
varjson.DATA = [];
// Push each of the values back into the array.
for (var o in temp) {
    varjson.DATA.push(temp[o]);
}

Here we are creating an object with the name as the key. The value is simply the original object from the array. Doing this, each replacement is O(1) and there is no need to check if it already exists. You then pull each of the values out and repopulate the array.

NOTE
For smaller arrays, your approach is slightly faster.

NOTE 2
This will not preserve the original order.

You can implement like a below logic. Suppose you want an array of values.

let test = [ {name:'test',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:30},
             {name:'test3',lastname:'kumar',age:47},
             {name:'test',lastname:'kumar',age:28},
             {name:'test4',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:29}]

let result1 = test.map(element => 
              { 
                 if (element.age === 30) 
                 {
                    return element.lastname;
                 }
              }).filter(notUndefined => notUndefined !== undefined);

output : ['kumar','kumar','kumar']

Have you tried using Form.ShowDialog() instead of Form.Show()?

ShowDialog shows your window as modal, which means you cannot interact with the parent form until it closes.

Just in case someone else is recently getting into this same issue, I'm using React Native 0.59.8 (tested with RN 0.60 as well) and I can confirm some of the other answers, here are the steps:

1. Uninstall the latest compiled version of your app installed you have on your device

2. Run react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

3. run cd android/ && ./gradlew assembleDebug

4. Get your app-debug.apk in folder android/app/build/outputs/apk/debug

good luck!

From MSDN Documentation

nvarchar [ ( n | max ) ]

Variable-length Unicode string data. n defines the string length and can be a value from 1 through 4,000. max indicates that the maximum storage size is 2^31-1 bytes (2 GB). The storage size, in bytes, is two times the actual length of data entered + 2 bytes

Update: I wrote a solution that doesn't require reading the entire file in one go. It's too big for a stackoverflow answer, but can be found here jsonstream.

You can use json.JSONDecoder.raw_decode to decode arbitarily big strings of "stacked" JSON (so long as they can fit in memory). raw_decode stops once it has a valid object and returns the last position where wasn't part of the parsed object. It's not documented, but you can pass this position back to raw_decode and it start parsing again from that position. Unfortunately, the Python json module doesn't accept strings that have prefixing whitespace. So we need to search to find the first none-whitespace part of your document.

from json import JSONDecoder, JSONDecodeError
import re

NOT_WHITESPACE = re.compile(r'[^\s]')

def decode_stacked(document, pos=0, decoder=JSONDecoder()):
    while True:
        match = NOT_WHITESPACE.search(document, pos)
        if not match:
            return
        pos = match.start()
        
        try:
            obj, pos = decoder.raw_decode(document, pos)
        except JSONDecodeError:
            # do something sensible if there's some error
            raise
        yield obj

s = """

{"a": 1}  


   [
1
,   
2
]


"""

for obj in decode_stacked(s):
    print(obj)

prints:

{'a': 1}
[1, 2]

What type of sql database are using (MSSQL, Oracle etc)? I believe what you have written is correct.

You could also write the first query like this:

SELECT s.sid, s.name
FROM Supplier s
WHERE (SELECT COUNT(DISTINCT pr.jid)
       FROM Supplies su, Projects pr
       WHERE su.sid = s.sid 
           AND pr.jid = su.jid) >= 2

It's a little more readable, and less mind-bending than trying to do it with GROUP BY. Performance may differ though.

unique_ptr is the light-weight smart pointer of choice if you just have a dynamic object somewhere for which one consumer has sole (hence "unique") responsibility -- maybe a wrapper class that needs to maintain some dynamically allocated object. unique_ptr has very little overhead. It is not copyable, but movable. Its type is template <typename D, typename Deleter> class unique_ptr;, so it depends on two template parameters.

unique_ptr is also what auto_ptr wanted to be in the old C++ but couldn't because of that language's limitations.

shared_ptr on the other hand is a very different animal. The obvious difference is that you can have many consumers sharing responsibility for a dynamic object (hence "shared"), and the object will only be destroyed when all shared pointers have gone away. Additionally you can have observing weak pointers which will intelligently be informed if the shared pointer they're following has disappeared.

Internally, shared_ptr has a lot more going on: There is a reference count, which is updated atomically to allow the use in concurrent code. Also, there's plenty of allocation going on, one for an internal bookkeeping "reference control block", and another (often) for the actual member object.

But there's another big difference: The shared pointers type is always template <typename T> class shared_ptr;, and this is despite the fact that you can initialize it with custom deleters and with custom allocators. The deleter and allocator are tracked using type erasure and virtual function dispatch, which adds to the internal weight of the class, but has the enormous advantage that different sorts of shared pointers of type T are all compatible, no matter the deletion and allocation details. Thus they truly express the concept of "shared responsibility for T" without burdening the consumer with the details!

Both shared_ptr and unique_ptr are designed to be passed by value (with the obvious movability requirement for the unique pointer). Neither should make you worried about the overhead, since their power is truly astounding, but if you have a choice, prefer unique_ptr, and only use shared_ptr if you really need shared responsibility.

I would argue against "abstract" tests. I think a test is a concrete idea and doesn't have an abstraction. If you have common elements, put them in helper methods or classes for everyone to use.

As for testing an abstract test class, make sure you ask yourself what it is you're testing. There are several approaches, and you should find out what works in your scenario. Are you trying to test out a new method in your subclass? Then have your tests only interact with that method. Are you testing the methods in your base class? Then probably have a separate fixture only for that class, and test each method individually with as many tests as necessary.

The above solution returned null in case of .rar file, using URLConnection.guessContentTypeFromName(url) worked in this case.

One way is to add a unique number to the end of the url:

$('#inquiry').load('/portal/?f=searchBilling&pid=' + $('#query').val()+'&uid='+uniqueId());

Where you write uniqueId() to return something different each time it's called.

usually when i work with remote location teams it is important for me that i have prior knowledge what change done by other teams in same file, before i follow git stages untrack-->staged-->commit for that i wrote an bash script which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on main branch

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | grep "modified" | awk "{print $2}" `
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool FETCH_HEAD $file ;
done

in above script i fetch remote main branch (not necessary its master branch)to FETCH_HEAD them make a list of my modified file only and compare modified files to git difftool

here many difftool supported by git, i configure 'Meld Diff Viewer' for good GUI comparison .

You can use a css selector combination a well

driver.find_element_by_css_selector("#fruits01 [value='1']").click()

Change the 1 in the attribute = value css selector to the value corresponding with the desired fruit.

Synchronized simply means that multiple threads if associated with single object can prevent dirty read and write if synchronized block is used on particular object. To give you more clarity , lets take an example :

class MyRunnable implements Runnable {
    int var = 10;
    @Override
    public void run() {
        call();
    }

    public void call() {
        synchronized (this) {
            for (int i = 0; i < 4; i++) {
                var++;
                System.out.println("Current Thread " + Thread.currentThread().getName() + " var value "+var);
            }
        }
    }
}

public class MutlipleThreadsRunnable {
    public static void main(String[] args) {
        MyRunnable runnable1 = new MyRunnable();
        MyRunnable runnable2 = new MyRunnable();
        Thread t1 = new Thread(runnable1);
        t1.setName("Thread -1");
        Thread t2 = new Thread(runnable2);
        t2.setName("Thread -2");
        Thread t3 = new Thread(runnable1);
        t3.setName("Thread -3");
        t1.start();
        t2.start();
        t3.start();
    }
}

We've created two MyRunnable class objects , runnable1 being shared with thread 1 and thread 3 & runnable2 being shared with thread 2 only. Now when t1 and t3 starts without synchronized being used , PFB output which suggest that both threads 1 and 3 simultaneously affecting var value where for thread 2 , var has its own memory.

Without Synchronized keyword

    Current Thread Thread -1 var value 11
    Current Thread Thread -2 var value 11
    Current Thread Thread -2 var value 12
    Current Thread Thread -2 var value 13
    Current Thread Thread -2 var value 14

    Current Thread Thread -1 var value 14
    Current Thread Thread -1 var value 17
    Current Thread Thread -3 var value 16
    Current Thread Thread -3 var value 18

Using Synchronzied, thread 3 waiting for thread 1 to complete in all scenarios. There are two locks acquired , one on runnable1 shared by thread 1 and thread 3 and another on runnable2 shared by thread 2 only.

Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11

    <tr>
       <td>

Here is another way of converting a xml to pandas data frame. For example i have parsing xml from a string but this logic holds good from reading file as well.

import pandas as pd
import xml.etree.ElementTree as ET

xml_str = '<?xml version="1.0" encoding="utf-8"?>\n<response>\n <head>\n  <code>\n   200\n  </code>\n </head>\n <body>\n  <data id="0" name="All Categories" t="2018052600" tg="1" type="category"/>\n  <data id="13" name="RealEstate.com.au [H]" t="2018052600" tg="1" type="publication"/>\n </body>\n</response>'

etree = ET.fromstring(xml_str)
dfcols = ['id', 'name']
df = pd.DataFrame(columns=dfcols)

for i in etree.iter(tag='data'):
    df = df.append(
        pd.Series([i.get('id'), i.get('name')], index=dfcols),
        ignore_index=True)

df.head()

You will have to use some sort of network sniffer if you want to get at this sort of data and you're likely to run into the same problem (pulling out the relevant data from the overall network traffic) with those that you do now with Wireshark.

Agree with Jewes, XmlReader is the better way to go, especially if working with a larger XML document or processing multiple in a loop - no need to parse the entire document if you only need the document root.

Here's a simplified version, using XmlReader and MoveToContent().

http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.movetocontent.aspx

using (XmlReader xmlReader = XmlReader.Create(p_fileName))
{
  if (xmlReader.MoveToContent() == XmlNodeType.Element)
    rootNodeName = xmlReader.Name;
}

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

Update: I've published a full skeleton Angular 2 project with OAuth2 integration on Github that shows the directive mentioned below in action.

One way to do that would be through the use of a directive. Unlike Angular 2 components, which are basically new HTML tags (with associated code) that you insert into your page, an attributive directive is an attribute that you put in a tag that causes some behavior to occur. Docs here.

The presence of your custom attribute causes things to happen to the component (or HTML element) that you placed the directive in. Consider this directive I use for my current Angular2/OAuth2 application:

import {Directive, OnDestroy} from 'angular2/core';
import {AuthService} from '../services/auth.service';
import {ROUTER_DIRECTIVES, Router, Location} from "angular2/router";

@Directive({
    selector: '[protected]'
})
export class ProtectedDirective implements OnDestroy {
    private sub:any = null;

    constructor(private authService:AuthService, private router:Router, private location:Location) {
        if (!authService.isAuthenticated()) {
            this.location.replaceState('/'); // clears browser history so they can't navigate with back button
            this.router.navigate(['PublicPage']);
        }

        this.sub = this.authService.subscribe((val) => {
            if (!val.authenticated) {
                this.location.replaceState('/'); // clears browser history so they can't navigate with back button
                this.router.navigate(['LoggedoutPage']); // tells them they've been logged out (somehow)
            }
        });
    }

    ngOnDestroy() {
        if (this.sub != null) {
            this.sub.unsubscribe();
        }
    }
}

This makes use of an Authentication service I wrote to determine whether or not the user is already logged in and also subscribes to the authentication event so that it can kick a user out if he or she logs out or times out.

You could do the same thing. You'd create a directive like mine that checks for the presence of a necessary cookie or other state information that indicates that the user is authenticated. If they don't have those flags you are looking for, redirect the user to your main public page (like I do) or your OAuth2 server (or whatever). You would put that directive attribute on any component that needs to be protected. In this case, it might be called protected like in the directive I pasted above.

<members-only-info [protected]></members-only-info>

Then you would want to navigate/redirect the user to a login view within your app, and handle the authentication there. You'd have to change the current route to the one you wanted to do that. So in that case you'd use dependency injection to get a Router object in your directive's constructor() function and then use the navigate() method to send the user to your login page (as in my example above).

This assumes that you have a series of routes somewhere controlling a <router-outlet> tag that looks something like this, perhaps:

@RouteConfig([
    {path: '/loggedout', name: 'LoggedoutPage', component: LoggedoutPageComponent, useAsDefault: true},
    {path: '/public', name: 'PublicPage', component: PublicPageComponent},
    {path: '/protected', name: 'ProtectedPage', component: ProtectedPageComponent}
])

If, instead, you needed to redirect the user to an external URL, such as your OAuth2 server, then you would have your directive do something like the following:

window.location.href="https://myserver.com/oauth2/authorize?redirect_uri=http://myAppServer.com/myAngular2App/callback&response_type=code&client_id=clientId&scope=my_scope

Actually I believe de-normalising the tags table might be a better way forward, depending on scale.

This way, the tags table simply has tagid, itemid, tagname.

You'll get duplicate tagnames, but it makes adding/removing/editing tags for specific items MUCH more simple. You don't have to create a new tag, remove the allocation of the old one and re-allocate a new one, you just edit the tagname.

For displaying a list of tags, you simply use DISTINCT or GROUP BY, and of course you can count how many times a tag is used easily, too.

How about this?

CREATE FUNCTION dbo.StripWWWandCom (@input VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @Input

    SET @Work = REPLACE(@Work, 'www.', '')
    SET @Work = REPLACE(@Work, '.com', '')

    RETURN @work
END

and then use:

SELECT ID, dbo.StripWWWandCom (WebsiteName)
FROM dbo.YourTable .....

Of course, this is severely limited in that it will only strip www. at the beginning and .com at the end - nothing else (so it won't work on other host machine names like smtp.yahoo.com and other internet domains such as .org, .edu, .de and etc.)

Who do you trust?

I've always considered this area too critical to trust a third party to manage the runtime security of your application. Once that component is cracked for one application, it's cracked for all applications. It happened to Discreet in five minutes once they went with a third-party license solution for 3ds Max years ago... Good times!

Seriously, consider rolling your own for having complete control over your algorithm. If you do, consider using components in your key along the lines of:

• License Name - the name of client (if any) you're licensing. Useful for managing company deployments - make them feel special to have a "personalised" name in the license information you supply them.
• Date of license expiry
• Number of users to run under the same license. This assumes you have a way of tracking running instances across a site, in a server-ish way
• Feature codes - to let you use the same licensing system across multiple features, and across multiple products. Of course if it's cracked for one product it's cracked for all.

Then checksum the hell out of them and add whatever (reversable) encryption you want to it to make it harder to crack.

To make a trial license key, simply have set values for the above values that translate as "trial mode".

And since this is now probably the most important code in your application/company, on top of/instead of obfuscation consider putting the decrypt routines in a native DLL file and simply P/Invoke to it.

Several companies I've worked for have adopted generalised approaches for this with great success. Or maybe the products weren't worth cracking ;)

The update from 3.2.x to 3.3.x broke some of the solutions explained here and on other threads because of the change: "Added transforms to improve carousel performance in modern browsers."

If you are using Bootstrap 3.3.x there's a solution here:
http://codepen.io/transportedman/pen/NPWRGq

Basically you need to add the "carousel-fade" class to your carousel so that you have:
<div class="carousel slide carousel-fade">

And then include the following CSS:

/*
  Bootstrap Carousel Fade Transition (for Bootstrap 3.3.x)
  CSS from:       http://codepen.io/transportedman/pen/NPWRGq
  and:            http://stackoverflow.com/questions/18548731/bootstrap-3-carousel-fading-to-new-slide-instead-of-sliding-to-new-slide
  Inspired from:  http://codepen.io/Rowno/pen/Afykb 
*/
.carousel-fade .carousel-inner .item {
  opacity: 0;
  transition-property: opacity;
}

.carousel-fade .carousel-inner .active {
  opacity: 1;
}

.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  left: 0;
  opacity: 0;
  z-index: 1;
}

.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
  opacity: 1;
}

.carousel-fade .carousel-control {
  z-index: 2;
}

/*
  WHAT IS NEW IN 3.3: "Added transforms to improve carousel performance in modern browsers."
  Need to override the 3.3 new styles for modern browsers & apply opacity
*/
@media all and (transform-3d), (-webkit-transform-3d) {
    .carousel-fade .carousel-inner > .item.next,
    .carousel-fade .carousel-inner > .item.active.right {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.prev,
    .carousel-fade .carousel-inner > .item.active.left {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.next.left,
    .carousel-fade .carousel-inner > .item.prev.right,
    .carousel-fade .carousel-inner > .item.active {
      opacity: 1;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
}

If you are after the side effects that happen within the loop, I'd personally go for the range() approach.

If you care about the result of whatever functions you call within the loop, I'd go for a list comprehension or map approach. Something like this:

def f(n):
    return n * n

results = [f(i) for i in range(50)]
# or using map:
results = map(f, range(50))

Building on the answer of JMax, use this formula for the dynamic named range to make the solution work for multiple rows:

=OFFSET(Sheet2!$A$1,MATCH(INDIRECT("Sheet1!"&ADDRESS(ROW(),COLUMN(),4))&"*",Sheet2!$A$1:$A$300,0)-1,0,COUNTA(Sheet2!$A:$A))

Please remember, if a WHERE clause is added, the cross join behaves as an inner join. For example, the following Transact-SQL queries produce the same result set. Please refer to http://technet.microsoft.com/en-us/library/ms190690(v=sql.105).aspx

Change the number of @grid-columns. Then use -offset. Changing the number of columns will allow you to control the amount of space between columns. E.g.

variables.less (approx line 294).

@grid-columns:              20;

someName.html

<div class="row">
  <div class="col-md-4 col-md-offset-1">First column</div>
  <div class="col-md-13 col-md-offset-1">Second column</div>
</div>

try this. It will solve your problem.

 var lastDayOfMonth = DateTime.DaysInMonth(int.Parse(ddlyear.SelectedValue), int.Parse(ddlmonth.SelectedValue));
DateTime tLastDayMonth = Convert.ToDateTime(lastDayOfMonth.ToString() + "/" + ddlmonth.SelectedValue + "/" + ddlyear.SelectedValue);

Perform rotation using transform: rotate(xdeg) and also apply overflow: hidden to the parent component to avoid overlapping effect

.div-parent {
   overflow: hidden
}

.div-child {
   transform: rotate(270deg);
}

TestGameTable.class.getResource("/unibo/lsb/res/dice.jpg");

• leading slash to denote the root of the classpath
• slashes instead of dots in the path
• you can call getResource() directly on the class.

The short answer: no.

The long answer:

Fixed formats work better for HTML emails. In my experience you're best off pretending it's 1999 when it comes to HTML emails. Be explicit and use HTML attributes (width="650") where ever possible in your table definitions, not CSS (style="width:650px"). Use fixed widths, no percentages. A table width of 650 pixels wide is a safe bet. Use inline CSS to set text properties.

It's not a matter of what works in "HTML emails", but rather the plethora of email clients and their limited (and sometimes deliberately so in the case of Gmail, Hotmail etc) ability to render HTML.

Step 1: check the return code: if($content === FALSE) { // handle error here... }

Step 2: suppress the warning by putting an error control operator (i.e. @) in front of the call to file_get_contents(): $content = @file_get_contents($site);

I don't know what you mean by "data dont get lost". Here's how you pass a normal 2D array to a function:

void myfunc(int arr[M][N]) { // M is optional, but N is required
  ..
}

int main() {
  int somearr[M][N];
  ...
  myfunc(somearr);
  ...
}

I know there is already an answer - and this is an old question - but I was wondering the same thing and after finding this answer I did a little experimentation on my own and had (IMO) a worthwhile addition to the discussion.

The non-visible characters can still be used in a folder name - a placeholder is inserted - but the sort on ASCII value still seems to hold.

I tested on Windows7, holding down the alt-key and typing in the ASCII code using the numeric keypad. I did not test very many, but was successful creating foldernames that started with ASCII 1, ASCII 2, and ASCII 3. Those correspond with SOH, STX and ETX. Respectively it displayed happy face, filled happy face, and filled heart.

I'm not sure if I can duplicate that here - but I will type them in on the next lines and submit.

?foldername

?foldername

?foldername

Use this query to check what is the Sequence Key with Schema and Table,

SELECT pg_get_serial_sequence('"SchemaName"."TableName"', 'KeyColumnName'); // output: "SequenceKey"

Use this query increase increment value one by one,

SELECT nextval('"SchemaName"."SequenceKey"'::regclass); // output 110

When inserting to table next incremented value will be used as the key (111).

Use this query to set specific value as the incremented value

SELECT setval('"SchemaName"."SequenceKey"', 120);

When inserting to table next incremented value will be used as the key (121).

A functional requirement describes what a software system should do, while non-functional requirements place constraints on how the system will do so.

Let me elaborate.

An example of a functional requirement would be:

• A system must send an email whenever a certain condition is met (e.g. an order is placed, a customer signs up, etc).

A related non-functional requirement for the system may be:

• Emails should be sent with a latency of no greater than 12 hours from such an activity.

The functional requirement is describing the behavior of the system as it relates to the system's functionality. The non-functional requirement elaborates a performance characteristic of the system.

Typically non-functional requirements fall into areas such as:

• Accessibility
• Capacity, current and forecast
• Compliance
• Documentation
• Disaster recovery
• Efficiency
• Effectiveness
• Extensibility
• Fault tolerance
• Interoperability
• Maintainability
• Privacy
• Portability
• Quality
• Reliability
• Resilience
• Response time
• Robustness
• Scalability
• Security
• Stability
• Supportability
• Testability

A more complete list is available at Wikipedia's entry for non-functional requirements.

Non-functional requirements are sometimes defined in terms of metrics (i.e. something that can be measured about the system) to make them more tangible. Non-functional requirements may also describe aspects of the system that don't relate to its execution, but rather to its evolution over time (e.g. maintainability, extensibility, documentation, etc.).

There is another way to do this. In case you need to set only one parameter, for example 'height':

TextView textView = (TextView)findViewById(R.id.text_view);
ViewGroup.LayoutParams params = textView.getLayoutParams();
params.height = ViewGroup.LayoutParams.WRAP_CONTENT;
textView.setLayoutParams(params);

In Python 3.6 the fastest way is still the WouterOvermeire one. Kikohs' proposal is slower than the other two options.

import timeit

setup = '''
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randint(32, 120, 100000).reshape(50000,2),columns=list('AB'))
df['A'] = df['A'].apply(chr)
'''

timeit.Timer('dict(zip(df.A,df.B))', setup=setup).repeat(7,500)
timeit.Timer('pd.Series(df.A.values,index=df.B).to_dict()', setup=setup).repeat(7,500)
timeit.Timer('df.set_index("A").to_dict()["B"]', setup=setup).repeat(7,500)

Results:

1.1214002349999777 s  # WouterOvermeire
1.1922008498571748 s  # Jeff
1.7034366211428602 s  # Kikohs

If is from a text file and and presuming name file are surrounded by white spaces this is a way:

$a = get-content c:\myfile.txt

$b = $a | select-string -pattern "\s.+\..{3,4}\s" | select -ExpandProperty matches | select -ExpandProperty value

$b | % {"File name:{0} - Extension:{1}" -f $_.substring(0, $_.lastindexof('.')) , $_.substring($_.lastindexof('.'), ($_.length - $_.lastindexof('.'))) }

If is a file you can use something like this based on your needs:

$a = dir .\my.file.xlsx # or $a = get-item c:\my.file.xlsx 

$a
    Directory: Microsoft.PowerShell.Core\FileSystem::C:\ps


Mode           LastWriteTime       Length Name
----           -------------       ------ ----
-a---      25/01/10    11.51          624 my.file.xlsx


$a.BaseName
my.file
$a.Extension
.xlsx

My answer is focused to a extended case derived from the one exposed at top.

Suppose you have group of elements from which you want to hide the child elements except first. As an example:

<html>
  <div class='some-group'>
     <div class='child child-0'>visible#1</div>
     <div class='child child-1'>xx</div>
     <div class='child child-2'>yy</div>
  </div>
  <div class='some-group'>
     <div class='child child-0'>visible#2</div>
     <div class='child child-1'>aa</div>
     <div class='child child-2'>bb</div>
  </div>
</html>

1. We want to hide all .child elements on every group. So this will not help because will hide all .child elements except visible#1:

   $('.child:not(:first)').hide();
   

2. The solution (in this extended case) will be:

   $('.some-group').each(function(i,group){
       $(group).find('.child:not(:first)').hide();
   });
   

You could wrapping the transaction over try..catch or even reverse them, here my example code I used to in laravel 5,, if you look deep inside DB:transaction() in Illuminate\Database\Connection that the same like you write manual transaction.

Laravel Transaction

public function transaction(Closure $callback)
    {
        $this->beginTransaction();

        try {
            $result = $callback($this);

            $this->commit();
        }

        catch (Exception $e) {
            $this->rollBack();

            throw $e;
        } catch (Throwable $e) {
            $this->rollBack();

            throw $e;
        }

        return $result;
    }

so you could write your code like this, and handle your exception like throw message back into your form via flash or redirect to another page. REMEMBER return inside closure is returned in transaction() so if you return redirect()->back() it won't redirect immediately, because the it returned at variable which handle the transaction.

Wrap Transaction

$result = DB::transaction(function () use ($request, $message) {
   try{

      // execute query 1
      // execute query 2
      // ..

      return redirect(route('account.article'));

   } catch (\Exception $e) {
       return redirect()->back()->withErrors(['error' => $e->getMessage()]);
    }
 });

// redirect the page
return $result;

then the alternative is throw boolean variable and handle redirect outside transaction function or if your need to retrieve why transaction failed you can get it from $e->getMessage() inside catch(Exception $e){...}

127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

Use PHP's empty() function. The following things are considered to be empty

"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)

For more details check empty function

configure your php.ini like this

SMTP = smtp.gmail.com

[mail function]
; XAMPP: Comment out this if you want to work with an SMTP Server like Mercury

; SMTP = smtp.gmail.com

; smtp_port = 465

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = postmaster@localhost

Try manually setting the levels of the factor on the x-axis. For example:

library(ggplot2)
# Automatic levels
ggplot(mtcars, aes(factor(cyl))) + geom_bar()    

# Manual levels
cyl_table <- table(mtcars$cyl)
cyl_levels <- names(cyl_table)[order(cyl_table)]
mtcars$cyl2 <- factor(mtcars$cyl, levels = cyl_levels)
# Just to be clear, the above line is no different than:
# mtcars$cyl2 <- factor(mtcars$cyl, levels = c("6","4","8"))
# You can manually set the levels in whatever order you please. 
ggplot(mtcars, aes(cyl2)) + geom_bar()

As James pointed out in his answer, reorder is the idiomatic way of reordering factor levels.

mtcars$cyl3 <- with(mtcars, reorder(cyl, cyl, function(x) -length(x)))
ggplot(mtcars, aes(cyl3)) + geom_bar()

I too got the same problem
I downloaded get-pip.py from https://bootstrap.pypa.io/get-pip.py

and then ran python2.7 get-pip.py for installing pip2.7

and then ran the pip install command with python2.7 as follows

For Ubuntu/Linux:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

For Mac OS X:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

this should work just fine as it did for me :)

Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

This question already has the answer for defining function pointers, however they can get very messy, especially if you are going to be passing them around your application. To avoid this unpleasantness I would recommend that you typedef the function pointer into something more readable. For example.

typedef void (*functiontype)();

Declares a function that returns void and takes no arguments. To create a function pointer to this type you can now do:

void dosomething() { }

functiontype func = &dosomething;
func();

For a function that returns an int and takes a char you would do

typedef int (*functiontype2)(char);

and to use it

int dosomethingwithchar(char a) { return 1; }

functiontype2 func2 = &dosomethingwithchar
int result = func2('a');

There are libraries that can help with turning function pointers into nice readable types. The boost function library is great and is well worth the effort!

boost::function<int (char a)> functiontype2;

is so much nicer than the above.

As in Oracle you can use NVL function in MySQL you can use IFNULL(columnaName, newValue) to achieve your desired result as in this example

SELECT column_name from table_name WHERE IFNULL(column_name,'') NOT LIKE '%_%';

try,

str_list = " ".join([str(ele) for ele in numlist])

this statement will give you each element of your list in string format

print("The list now looks like [{0}]".format(str_list))

and,

change print(numlist.pop(2)+" has been removed") to

print("{0} has been removed".format(numlist.pop(2)))

as well.

Add the following dependency to your pom.xml

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.5.2</version>
</dependency>

This problem occured to me in raspberry pi. I had logged in through VNC client The problem persisted despite setting and exporting the GOPATH. Then Ran the "go get" command without sudo and it worked perfectly.

If you are only trying to change the include paths for a project and not for all solutions then in Visual Studio 2008 do this: Right-click on the name of the project in the Solution Navigator. From the popup menu select Properties. In the property pages dialog select Configuration Properties->C/C++/General. Click in the text box next to the "Additional Include Files" label and browse for the appropriate directory. Select OK.

What annoys me is that some of the answers to the original question asked do not apply to the version of Visual Studio that was mentioned.

This does not have anything to do with character encodings such as UTF-8 or ASCII. The string you have there is URL encoded. This kind of encoding is something entirely different than character encoding.

Try something like this:

try {
    String result = java.net.URLDecoder.decode(url, StandardCharsets.UTF_8.name());
} catch (UnsupportedEncodingException e) {
    // not going to happen - value came from JDK's own StandardCharsets
}

Java 10 added direct support for Charset to the API, meaning there's no need to catch UnsupportedEncodingException:

String result = java.net.URLDecoder.decode(url, StandardCharsets.UTF_8);

Note that a character encoding (such as UTF-8 or ASCII) is what determines the mapping of characters to raw bytes. For a good intro to character encodings, see this article.

I had similar issue. The fix was ensure that your ctrollers are not only defined within script tags toward the bottom of your index.html just before the closing tag for body but ALSO validating that they are in order of how your folder is structured.

<script src="scripts/app.js"></script>
<script src="scripts/controllers/main.js"></script>
<script src="scripts/controllers/Administration.js"></script>
<script src="scripts/controllers/Leaderboard.js"></script>
<script src="scripts/controllers/Login.js"></script>
<script src="scripts/controllers/registration.js"></script>

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

I wrote this a few months prior to the inclusion of git-credential in TortoiseGit. Given the number of large security holes found in the last few years and how much I've learned about network security, I would HIGHLY recommend you use a unique (minimum 2048-bit RSA) SSH key for every server you connect to.

The below syntax is still available, though there are far better tools available today like git-credential that the accepted answer tells you how to use. Do that instead.

Try changing the remote URL to https://[email protected]/username/repo.git where username is your github username and repo is the name of your repository.

If you also want to store your password (not recommended), the URL would look like this: https://username:[email protected]/username/repo.git.

There's also another way to store the password from this github help article: https://help.github.com/articles/set-up-git#password-caching

SHOW CREATE TABLE bar;

you will get a create statement for that table, edit the table name, or anything else you like, and then execute it.

This will allow you to copy the indexes and also manually tweak the table creation.

You can also run the query within a program.

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

I'm unsure of the context on why this was needed, so this may not return enough information for you but this is what I was able to do:

if(typeof(ModelName).GetProperty("Name of Property") != null)
{
//whatevver you were wanting to do.
}

In my case I'm running through properties from a form submission and also have default values to use if the entry is left blank - so I needed to know if the there was a value to use - I prefixed all my default values in the model with Default so all I needed to do is check if there was a property that started with that.

A Java String is internally always encoded in UTF-16 - but you really should think about it like this: an encoding is a way to translate between Strings and bytes.

So if you have an encoding problem, by the time you have String, it's too late to fix. You need to fix the place where you create that String from a file, DB or network connection.

Try this

java -jar <jar-file-name>.jar

After importing the scripting runtime as described above you have to make some slighty modification to get it working in Excel 2010 (my version). Into the following code I've also add the code used to the user to pick a file.

Dim intChoice As Integer
Dim strPath As String

' Select one file
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False

' Show the selection window
intChoice = Application.FileDialog(msoFileDialogOpen).Show

' Get back the user option
If intChoice <> 0 Then
    strPath = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Else
    Exit Sub
End If

Dim FSO As New Scripting.FileSystemObject
Dim fsoStream As Scripting.TextStream
Dim strLine As String

Set fsoStream = FSO.OpenTextFile(strPath)

Do Until fsoStream.AtEndOfStream = True
    strLine = fsoStream.ReadLine
    ' ... do your work ...
Loop

fsoStream.Close
Set FSO = Nothing

Hope it help!

Here's a one liner (yes, it is similar to user333700's, but a little more straightforward):

>>> import numpy as np
>>> arr = np.array([[ 0.96488889, 0.73641667, 0.67521429, 0.592875, 0.53172222], 
                [ 0.78008333, 0.5938125, 0.481, 0.39883333, 0.]])
>>> print arr[arr.all(1)]
array([[ 0.96488889,  0.73641667,  0.67521429,  0.592875  ,  0.53172222]])

By the way, this method is much, much faster than the masked array method for large matrices. For a 2048 x 5 matrix, this method is about 1000x faster.

By the way, user333700's method (from his comment) was slightly faster in my tests, though it boggles my mind why.

@media (max-width: @iphone-screen) {
  background-attachment:inherit;    
  background-size:cover;
  -webkit-background-size:cover;
}

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

Why are you using WMI? Can't you use the standard .NET functionality?

System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName;

None of the solutions above worked for me, I tried same app with different device it worked. Finally I noticed that the application is disabled.

1. Go to setting/apps (on the phone)
2. If it is disabled, remove it

That was the solution for my case

Decimal is a value type, so if you wish to check whether it has a value other than the value it was initialised with (zero) you can use the condition myDecimal != default(decimal).

Otherwise you should possibly consider the use of a nullable (decimal?) type and the use a condition such as myNullableDecimal.HasValue

From your other posts, I guess you want to learn a new language to get new skills. My advice is that the language is not really important, what is important is the quality of its community (advice, but also existing code you can read and learn from) and the available libraries/frameworks. In this respect, I think the "C family" is not the best choice for you: web libraries and frameworks are few, not portable and not great, and coding style of code you can study varies a lot and may confuse you a lot (although C is my favorite language).

I would advise to just learn C, and try to really understand the concept of pointers, then move to other languages more adapted to the web (Python or JavaScript comes to mind - or even Java). Also, in the C family, Objective-C has the best mix of power and simplicity in my opinion, but is a niche player.

string filePath = @"C:\styles\MyStyles.css"; 
string siteURL = "http://example.org/";

    { 
        if (!System.IO.File.Exists(filePath)) 
            throw new FileNotFoundException("File not found.", filePath);                     

        SPFolder libFolder = oWeb.Folders[libraryName]; 

        // Prepare to upload 
        string fileName = System.IO.Path.GetFileName(filePath); 
        FileStream fileStream = File.OpenRead(filePath); 

        //Check the existing File out if the Library Requires CheckOut
        if (libFolder.RequiresCheckout)
        {
            try {
                SPFile fileOld = libFolder.Files[fileName];
                fileOld.CheckOut();
            } catch {}
        }

        // Upload document 
        SPFile spfile = libFolder.Files.Add(fileName, fileStream, true); 

        // Commit  
        myLibrary.Update(); 

        //Check the File in and Publish a Major Version

This may be because you didn't have the access right to push a commit to a branch such as master. You can ask the maintainer to give you the right to push commits.

Get comfortable with zip. It comes in handy when dealing with column data.

df['new_col'] = list(zip(df.lat, df.long))

It's less complicated and faster than using apply or map. Something like np.dstack is twice as fast as zip, but wouldn't give you tuples.

In ascending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]))

or in descending order you can use:

sorted_data= sorted(non_sorted_data, key=lambda k: (k[1],k[0]),reverse=True)

R is an environment for statistical data analysis and graphics. MATLAB's origins are in numerical computation. The basic language implementations have many features in common if you use them for for data manipulation (e.g., matrix/vector operations).

R has statistical functionality hard to find elsewhere (>2000 Packages on CRAN), and lots of statisticians use it. On the other hand, MATLAB has lots of (expensive) toolboxes for engineering applications like

• image processing/image acquisition,
• filter design,
• fuzzy logic/fuzzy control,
• partial differential equations,
• etc.

You can use

$objWorksheet->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
$objWorksheet->getActiveSheet()->getColumnDimension('A')->setWidth(100);

or define auto-size:

$objWorksheet->getRowDimension('1')->setRowHeight(-1);

Late simple example:

from os import path, getcwd, chdir

def print_my_path():
    print('cwd:     {}'.format(getcwd()))
    print('__file__:{}'.format(__file__))
    print('abspath: {}'.format(path.abspath(__file__)))

print_my_path()

chdir('..')

print_my_path()

Under Python-2.*, the second call incorrectly determines the path.abspath(__file__) based on the current directory:

cwd:     C:\codes\py
__file__:cwd_mayhem.py
abspath: C:\codes\py\cwd_mayhem.py
cwd:     C:\codes
__file__:cwd_mayhem.py
abspath: C:\codes\cwd_mayhem.py

As noted by @techtonik, in Python 3.4+, this will work fine since __file__ returns an absolute path.

I landed on this question as I was looking for a clean iterator of columns only (Series, no names).

Unless I am mistaken, there is no such thing, which, if true, is a bit annoying. In particular, one would sometimes like to assign a few individual columns (Series) to variables, e.g.:

x, y = df[['x', 'y']]  # does not work

There is df.items() that gets close, but it gives an iterator of tuples (column_name, column_series). Interestingly, there is a corresponding df.keys() which returns df.columns, i.e. the column names as an Index, so a, b = df[['x', 'y']].keys() assigns properly a='x' and b='y'. But there is no corresponding df.values(), and for good reason, as df.values is a property and returns the underlying numpy array.

One (inelegant) way is to do:

x, y = (v for _, v in df[['x', 'y']].items())

but it's less pythonic than I'd like.

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

Try:

def (value1, value2) = '1128-2'.tokenize( '-' )

Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/

Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):

=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))

To translate your specific example, you would use:

=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))

Use mysql_num_rows(), to check if rows are available or not

$result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName' LIMIT 1");
$num_rows = mysql_num_rows($result);

if ($num_rows > 0) {
  // do something
}
else {
  // do something else
}

Not the best answer and not the cleanest, but I think it's more permissive. Like if you want to use the same filters for all of your checks. Actually .filter() works with an array and return a filtered array (wich I find more easy to use too).

var str1 = 'hi, how do you do?';
var str2 = 'regular string';
var conditions = ["hello", "hi", "howdy"];

// Solve the problem
var res1 = [str1].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));
var res2 = [str2].filter(data => data.includes(conditions[0]) || data.includes(conditions[1]) || data.includes(conditions[2]));

console.log(res1); // ["hi, how do you do?"]
console.log(res2); // []


// More useful in this case
var text = [str1, str2, "hello world"];

// Apply some filters on data
var res3 = text.filter(data => data.includes(conditions[0]) && data.includes(conditions[2]));
// You may use again the same filters for a different check
var res4 = text.filter(data => data.includes(conditions[0]) || data.includes(conditions[1]));

console.log(res3); // []
console.log(res4); // ["hi, how do you do?", "hello world"]

You can just move node_modules into a / folder.

How it works

FROM node:0.12

WORKDIR /worker

COPY package.json /worker/
RUN npm install \
  && mv node_modules /node_modules

COPY . /worker/

• View.getContext(): Returns the context the view is currently running in. Usually the currently active Activity.

• Activity.getApplicationContext(): Returns the context for the entire application (the process all the Activities are running inside of). Use this instead of the current Activity context if you need a context tied to the lifecycle of the entire application, not just the current Activity.

• ContextWrapper.getBaseContext(): If you need access to a Context from within another context, you use a ContextWrapper. The Context referred to from inside that ContextWrapper is accessed via getBaseContext().

How about this?

#include <cstdio>

int main()
{
    unsigned int n = 1;
    char *p = 0;

    p = (char*)&n;
    if (*p == 1)
        std::printf("Little Endian\n");
    else 
        if (*(p + sizeof(int) - 1) == 1)
            std::printf("Big Endian\n");
        else
            std::printf("What the crap?\n");
    return 0;
}

I believe if you used the double data type, the re-calculation in Excel would work just fine.

Did a quick google. Seems that to find the file size you do this,

long size = f.length();

The differences between the three methods you posted can be found here

getFreeSpace() and getTotalSpace() are pretty self explanatory, getUsableSpace() seems to be the space that the JVM can use, which in most cases will be the same as the amount of free space.
