event.key === "Backspace"

More recent and much cleaner: use event.key. No more arbitrary number codes!

input.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Backspace" || key === "Delete") {
        return false;
    }
});

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests

You can replace @requests with @complete_path_to_json_file

Note: @is important before the file path

You can extend PDOStatement class to capture the bounded variables and store them for later use. Then 2 methods may be added, one for variable sanitizing ( debugBindedVariables ) and another to print the query with those variables ( debugQuery ):

class DebugPDOStatement extends \PDOStatement{
  private $bound_variables=array();
  protected $pdo;

  protected function __construct($pdo) {
    $this->pdo = $pdo;
  }

  public function bindValue($parameter, $value, $data_type=\PDO::PARAM_STR){
    $this->bound_variables[$parameter] = (object) array('type'=>$data_type, 'value'=>$value);
    return parent::bindValue($parameter, $value, $data_type);
  }

  public function bindParam($parameter, &$variable, $data_type=\PDO::PARAM_STR, $length=NULL , $driver_options=NULL){
    $this->bound_variables[$parameter] = (object) array('type'=>$data_type, 'value'=>&$variable);
    return parent::bindParam($parameter, $variable, $data_type, $length, $driver_options);
  }

  public function debugBindedVariables(){
    $vars=array();

    foreach($this->bound_variables as $key=>$val){
      $vars[$key] = $val->value;

      if($vars[$key]===NULL)
        continue;

      switch($val->type){
        case \PDO::PARAM_STR: $type = 'string'; break;
        case \PDO::PARAM_BOOL: $type = 'boolean'; break;
        case \PDO::PARAM_INT: $type = 'integer'; break;
        case \PDO::PARAM_NULL: $type = 'null'; break;
        default: $type = FALSE;
      }

      if($type !== FALSE)
        settype($vars[$key], $type);
    }

    if(is_numeric(key($vars)))
      ksort($vars);

    return $vars;
  }

  public function debugQuery(){
    $queryString = $this->queryString;

    $vars=$this->debugBindedVariables();
    $params_are_numeric=is_numeric(key($vars));

    foreach($vars as $key=>&$var){
      switch(gettype($var)){
        case 'string': $var = "'{$var}'"; break;
        case 'integer': $var = "{$var}"; break;
        case 'boolean': $var = $var ? 'TRUE' : 'FALSE'; break;
        case 'NULL': $var = 'NULL';
        default:
      }
    }

    if($params_are_numeric){
      $queryString = preg_replace_callback( '/\?/', function($match) use( &$vars) { return array_shift($vars); }, $queryString);
    }else{
      $queryString = strtr($queryString, $vars);
    }

    echo $queryString.PHP_EOL;
  }
}


class DebugPDO extends \PDO{
  public function __construct($dsn, $username="", $password="", $driver_options=array()) {
    $driver_options[\PDO::ATTR_STATEMENT_CLASS] = array('DebugPDOStatement', array($this));
    $driver_options[\PDO::ATTR_PERSISTENT] = FALSE;
    parent::__construct($dsn,$username,$password, $driver_options);
  }
}

And then you can use this inherited class for debugging purpouses.

$dbh = new DebugPDO('mysql:host=localhost;dbname=test;','user','pass');

$var='user_test';
$sql=$dbh->prepare("SELECT user FROM users WHERE user = :test");
$sql->bindValue(':test', $var, PDO::PARAM_STR);
$sql->execute();

$sql->debugQuery();
print_r($sql->debugBindedVariables());

Resulting in

SELECT user FROM users WHERE user = 'user_test'

Array ( [:test] => user_test )

Use the ALTER USER command rather than trying to update a USER row. Keep in mind that there may be more than one 'root' user, because user entities are qualified also by the machine from which they connect

https://dev.mysql.com/doc/refman/5.7/en/alter-user.html

For example.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new-password' 
ALTER USER 'root'@'*' IDENTIFIED BY 'new-password' 

I've been trying to deploy a simple Angular 7 application, to an Azure Web App. Everything worked fine, until the point where you refreshed the page. Doing so, was presenting me with an 500 error - moved content. I've read both on the Angular docs and in around a good few forums, that I need to add a web.config file to my deployed solution and make sure the rewrite rule fallback to the index.html file. After hours of frustration and trial and error tests, I've found the error was quite simple: adding a tag around my file markup.

If you bracket the @ you can use it directly

declare @TEMP table (ID int, Name varchar(max))
insert into @temp values (1,'one'), (2,'two')

SELECT * FROM @TEMP 
WHERE [@TEMP].[ID] = 1

If by 'td value' you mean text inside of td, then:

document.getElementById('td-id').innerHTML

Yes. Use WindowBuilder Pro (provided by Google). It supports SWT and Swing as well with multiple layouts (Group layout, MiGLayout etc.) It's integrated out of the box with Eclipse Indigo, but you can install plugin on previous versions (3.4/3.5/3.6):

if the number has a decimal points, you can use below

using System;
using System.Text.RegularExpressions;

namespace Rextester
{
    public class Program
    {
        public static void Main(string[] args)
        {
            //Your code goes here
            Console.WriteLine(Regex.Match("anything 876.8 anything", @"\d+\.*\d*").Value);
            Console.WriteLine(Regex.Match("anything 876 anything", @"\d+\.*\d*").Value);
            Console.WriteLine(Regex.Match("$876435", @"\d+\.*\d*").Value);
            Console.WriteLine(Regex.Match("$876.435", @"\d+\.*\d*").Value);
        }
    }
}

results :

"anything 876.8 anything" ==> 876.8

"anything 876 anything" ==> 876

"$876435" ==> 876435

"$876.435" ==> 876.435

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

Stuarts' answer is correct, but if you are not sure if you are saving the titles in lowercase, you can also make a case insensitive search

There are a lot of answered questions in Stack Overflow with more data on this:

Example 1

Example 2

Use a command like:

git diff file_2.rb

See the git diff documentation for full information on the kinds of things you can get differences for.

Normally, git diff by itself shows all the changes in the whole repository (not just the current directory).

I spent a lot of time researching this and learning how it all works, after really messing up the event triggers. Since there was so much scattered info I decided to share what I have found to work all in one place, step by step as follows:

1) Open VBA Editor, under VBA Project (YourWorkBookName.xlsm) open Microsoft Excel Object and select the Sheet to which the change event will pertain.

2) The default code view is "General." From the drop-down list at the top middle, select "Worksheet."

3) Private Sub Worksheet_SelectionChange is already there as it should be, leave it alone. Copy/Paste Mike Rosenblum's code from above and change the .Range reference to the cell for which you are watching for a change (B3, in my case). Do not place your Macro yet, however (I removed the word "Macro" after "Then"):

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target, Me.Range("H5")) Is Nothing Then
End Sub

or from the drop-down list at the top left, select "Change" and in the space between Private Sub and End Sub, paste If Not Intersect(Target, Me.Range("H5")) Is Nothing Then

4) On the line after "Then" turn off events so that when you call your macro, it does not trigger events and try to run this Worksheet_Change again in a never ending cycle that crashes Excel and/or otherwise messes everything up:

Application.EnableEvents = False

5) Call your macro

Call YourMacroName

6) Turn events back on so the next change (and any/all other events) trigger:

Application.EnableEvents = True

7) End the If block and the Sub:

    End If
End Sub

The entire code:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target, Me.Range("B3")) Is Nothing Then
        Application.EnableEvents = False
        Call UpdateAndViewOnly
        Application.EnableEvents = True
    End If
End Sub

This takes turning events on/off out of the Modules which creates problems and simply lets the change trigger, turns off events, runs your macro and turns events back on.

If you are using java 8, you can create Comparator by this method:

Comparator.comparingInt(i -> i);

if you would like to compare with reversed order:

Comparator.comparingInt(i -> -i);

You can use Intent

Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
mIntent.putExtra("data", data);
startActivity(mIntent);

Another way could be using singleton pattern also:

public class DataHolder {

 private static DataHolder dataHolder;
 private List<Model> dataList;

 public void setDataList(List<Model>dataList) {
    this.dataList = dataList;
 }

 public List<Model> getDataList() {
    return dataList;
 }

 public synchronized static DataHolder getInstance() {
    if (dataHolder == null) {
       dataHolder = new DataHolder();
    }
    return dataHolder;
 }
}

From your FirstActivity

private List<Model> dataList = new ArrayList<>();
DataHolder.getInstance().setDataList(dataList);

On SecondActivity

private List<Model> dataList = DataHolder.getInstance().getDataList();

Just a tip!--make sure you up the z-index on the element you want to be over the embedded video. I added the wmode querystring, and it still didn't work...until I upped the z-index of the other element. :)

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

git rm --cached *.FileExtension

This must ignore all files from this extension

You can use to way below. It's very simple, but similar to the good answer given by Charlie Haley.

df1 = df.pop('b') # remove column b and store it in df1
df2 = df.pop('x') # remove column x and store it in df2
df['b']=df1 # add b series as a 'new' column.
df['x']=df2 # add b series as a 'new' column.

Now you have your dataframe with the columns 'b' and 'x' in the end. You can see this video from OSPY : https://youtu.be/RlbO27N3Xg4

Well, since your on a shared server, you can't do anything about it. They usually set the max execution time so that you can't override it. I suggest you contact them.

This error occurred for me when using window.location.reload(). Replacing with window.location = window.location.href solved the problem.

Try this piece of code:

$first = $string[0]; 
if($first == 'A' || $first == 'E' || $first == 'I' || $first == 'O' || $first == 'U') {
   $v='starts with vowel';
} 
else {
   $v='does not start with vowel';
}

Use printf("%ld",a);

Have a look at format specifiers for printf

SQL does not do that. The order of the tuples in the table are not ordered by insertion date. A lot of people include a column that stores that date of insertion in order to get around this issue.

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

I would use Joda Time, parse the time as a LocalTime, and then use

time = time.plusMinutes(10);

Short but complete program to demonstrate this:

import org.joda.time.*;
import org.joda.time.format.*;

public class Test {
    public static void main(String[] args) {
        DateTimeFormatter formatter = DateTimeFormat.forPattern("HH:mm");
        LocalTime time = formatter.parseLocalTime("14:10");
        time = time.plusMinutes(10);
        System.out.println(formatter.print(time));
    }       
}

Note that I would definitely use Joda Time instead of java.util.Date/Calendar if you possibly can - it's a much nicer API.

This streams PCM data but you could modify the code to stream mp3 or Speex

Java does have a logical XOR operator, it is ^ (as in a ^ b).

Apart from that, you can't define new operators in Java.

Edit: Here's an example:

public static void main(String[] args) {
    boolean[] all = { false, true };
    for (boolean a : all) {
        for (boolean b: all) {
            boolean c = a ^ b;
            System.out.println(a + " ^ " + b + " = " + c);
        }
    }
}

Output:

false ^ false = false
false ^ true = true
true ^ false = true
true ^ true = false

In my case I had to change the <VirtualHost *> back to <VirtualHost *:80> (which is the default on Ubuntu). Otherwise, the port 443 wasn't using SSL and was sending plain HTML back to the browser.

You can check whether this is your case quite easily: just connect to your server http://www.example.com:443. If you see plain HTML, your Apache is not using SSL on port 443 at all, most probably due to a VirtualHost misconfiguration.

Cheers!

Based on the existing answers, here's a step-by-step guide to sending automated e-mails over SMTP, using a GMail account, from the command line, without disclosing the password.

Requirements

First, install the following software packages:

• Expect
• OpenSSL
• Core Utils (base64)

These instructions assume a Linux operating system, but should be reasonably easy to port to Windows (via Cygwin or native equivalents), or other operating system.

Authentication

Save the following shell script as authentication.sh:

#!/bin/bash

# Asks for a username and password, then spits out the encoded value for
# use with authentication against SMTP servers.

echo -n "Email (shown): "
read email
echo -n "Password (hidden): "
read -s password
echo

TEXT="\0$email\0$password"

echo -ne $TEXT | base64

Make it executable and run it as follows:

chmod +x authentication.sh
./authentication.sh

When prompted, provide your e-mail address and password. This will look something like:

Email (shown): [email protected]
Password (hidden): 
AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==

Copy the last line (AGJ...==), as this will be used for authentication.

Notification

Save the following expect script as notify.sh (note the first line refers to the expect program):

#!/usr/bin/expect

set address "[lindex $argv 0]"
set subject "[lindex $argv 1]"
set ts_date "[lindex $argv 2]"
set ts_time "[lindex $argv 3]"

set timeout 10
spawn openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof 

expect "220" {
  send "EHLO localhost\n"

  expect "250" {
    send "AUTH PLAIN YOUR_AUTHENTICATION_CODE\n"

    expect "235" {
      send "MAIL FROM: <YOUR_EMAIL_ADDRESS>\n"

      expect "250" {
        send "RCPT TO: <$address>\n"

        expect "250" {
          send "DATA\n"

          expect "354" {
            send "Subject: $subject\n\n"
            send "Email sent on $ts_date at $ts_time.\n"
            send "\n.\n"

            expect "250" {
                send "quit\n"
            }
          }
        }
      }
    }
  }
}

Make the following changes:

1. Paste over YOUR_AUTHENTICATION_CODE with the authentication code generated by the authentication script.
2. Change YOUR_EMAIL_ADDRESS with the e-mail address used to generate the authentication code.
3. Save the file.

For example (note the angle brackets are retained for the e-mail address):

send "AUTH PLAIN AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==\n"
send "MAIL FROM: <[email protected]>\n"

Lastly, make the notify script executable as follows:

chmod +x notify.sh

Send E-mail

Send an e-mail from the command line as follows:

./notify.sh [email protected] "Command Line" "March 14" "15:52"

i'm new to this but a switch statement will defenitely work

#include <stdio.h>

enum mycolor;

int main(int argc, const char * argv[])

{
enum Days{Sunday=1,Monday=2,Tuesday=3,Wednesday=4,Thursday=5,Friday=6,Saturday=7};

enum Days TheDay;


printf("Please enter the day of the week (0 to 6)\n");

scanf("%d",&TheDay);

switch (TheDay)
 {

case Sunday:
        printf("the selected day is sunday");
        break;
    case Monday:
        printf("the selected day is monday");
        break;
    case Tuesday:
        printf("the selected day is Tuesday");
        break;
    case Wednesday:
        printf("the selected day is Wednesday");
        break;
    case Thursday:
        printf("the selected day is thursday");
        break;
    case Friday:
        printf("the selected day is friday");
        break;
    case Saturday:
        printf("the selected day is Saturaday");
        break;
    default:
        break;
}

return 0;
}

My preferred way is a bit long, but has some advantages over the other answers:

• It can combine an indefinite number of arrays at once
• It can combine arrays with non-arrays (objects, strings, integers, etc.)
• It accounts for the possibility that one or more of the arrays may contain objects
• It allows the user to choose the base of the new array (0, 1, etc.)

Here it is:

Function combineArrays(ByVal toCombine As Variant, Optional ByVal newBase As Long = 1)
'Combines an array of one or more 1d arrays, objects, or values into a single 1d array
'newBase parameter indicates start position of new array (0, 1, etc.)
'Example usage:
    'combineArrays(Array(Array(1,2,3),Array(4,5,6),Array(7,8))) -> Array(1,2,3,4,5,6,7,8)
    'combineArrays(Array("Cat",Array(2,3,4))) -> Array("Cat",2,3,4)
    'combineArrays(Array("Cat",ActiveSheet)) -> Array("Cat",ActiveSheet)
    'combineArrays(Array(ThisWorkbook)) -> Array(ThisWorkbook)
    'combineArrays("Cat") -> Array("Cat")

    Dim tempObj As Object
    Dim tempVal As Variant

    If Not IsArray(toCombine) Then
        If IsObject(toCombine) Then
            Set tempObj = toCombine
            ReDim toCombine(newBase To newBase)
            Set toCombine(newBase) = tempObj
        Else
            tempVal = toCombine
            ReDim toCombine(newBase To newBase)
            toCombine(newBase) = tempVal
        End If
        combineArrays = toCombine
        Exit Function
    End If

    Dim i As Long
    Dim tempArr As Variant
    Dim newMax As Long
    newMax = 0

    For i = LBound(toCombine) To UBound(toCombine)
        If Not IsArray(toCombine(i)) Then
            If IsObject(toCombine(i)) Then
                Set tempObj = toCombine(i)
                ReDim tempArr(1 To 1)
                Set tempArr(1) = tempObj
                toCombine(i) = tempArr
            Else
                tempVal = toCombine(i)
                ReDim tempArr(1 To 1)
                tempArr(1) = tempVal
                toCombine(i) = tempArr
            End If
            newMax = newMax + 1
        Else
            newMax = newMax + (UBound(toCombine(i)) + LBound(toCombine(i)) - 1)
        End If
    Next
    newMax = newMax + (newBase - 1)

    ReDim newArr(newBase To newMax)
    i = newBase
    Dim j As Long
    Dim k As Long
    For j = LBound(toCombine) To UBound(toCombine)
        For k = LBound(toCombine(j)) To UBound(toCombine(j))
            If IsObject(toCombine(j)(k)) Then
                Set newArr(i) = toCombine(j)(k)
            Else
                newArr(i) = toCombine(j)(k)
            End If
            i = i + 1
        Next
    Next

    combineArrays = newArr

End Function

It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************  TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif

StackTrace

This Highly depends on what you are looking for... But this should get the class and method that called this method within this object directly.

• index 0 = Thread
• index 1 = this
• index 2 = direct caller, can be self.
• index 3 ... n = classes and methods that called each other to get to the index 2 and below.

For Class/Method/File name:

Thread.currentThread().getStackTrace()[2].getClassName();
Thread.currentThread().getStackTrace()[2].getMethodName();
Thread.currentThread().getStackTrace()[2].getFileName();

For Class:

Class.forName(Thread.currentThread().getStackTrace()[2].getClassName())

FYI: Class.forName() throws a ClassNotFoundException which is NOT runtime. Youll need try catch.

Also, if you are looking to ignore the calls within the class itself, you have to add some looping with logic to check for that particular thing.

Something like... (I have not tested this piece of code so beware)

StackTraceElement[] stes = Thread.currentThread().getStackTrace();
for(int i=2;i<stes.length;i++)
  if(!stes[i].getClassName().equals(this.getClass().getName()))
    return stes[i].getClassName();

StackWalker

StackWalker StackFrame

Note that this is not an extensive guide but an example of the possibility.

Prints the Class of each StackFrame (by grabbing the Class reference)

StackWalker.getInstance(Option.RETAIN_CLASS_REFERENCE)
    .forEach(frame -> System.out.println(frame.getDeclaringClass()));

Does the same thing but first collects the stream into a List. Just for demonstration purposes.

StackWalker.getInstance(Option.RETAIN_CLASS_REFERENCE)
    .walk(stream -> stream.collect(Collectors.toList()))
    .forEach(frame -> System.out.println(frame.getDeclaringClass()));

Either set the enum name to be the same as the string you want or, more generally,you can associate arbitrary attributes with your enum values:

enum Strings {
   STRING_ONE("ONE"), STRING_TWO("TWO");
   private final String stringValue;
   Strings(final String s) { stringValue = s; }
   public String toString() { return stringValue; }
   // further methods, attributes, etc.
}

It's important to have the constants at the top, and the methods/attributes at the bottom.

According to javadocs:

@Deprecated
public int getYear()

Deprecated. As of JDK version 1.1, replaced by Calendar.get(Calendar.YEAR) - 1900.

Returns a value that is the result of subtracting 1900 from the year that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone.

Returns: the year represented by this date, minus 1900.

See Also: Calendar

So 112 is the correct output. I would follow the advice in the Javadoc or use JodaTime instead.

If you open the php.ini file in wamp, you will find these two lines:

smtp_server
smtp_port

Add the server and port number for your host (you may need to contact them for details)

The following two lines don't exist:

auth_username
auth_password

So you will need to add them to be able to send mail from a server that requires authentication. So an example may be:

smtp_server = mail.example.com
smtp_port = 26
auth_username = [email protected]
auth_password = example_password

Not sure why the grep method is not working for me when using npm test. This works though. I also need to specify the test folder also for some reason.

npm test -- test/sometest.js

you can use .find so in your example

   var projects = [
            {
                value: "jquery",
                label: "jQuery",
                desc: "the write less, do more, JavaScript library",
                icon: "jquery_32x32.png"
            },
            {
                value: "jquery-ui",
                label: "jQuery UI",
                desc: "the official user interface library for jQuery",
                icon: "jqueryui_32x32.png"
            },
            {
                value: "sizzlejs",
                label: "Sizzle JS",
                desc: "a pure-JavaScript CSS selector engine",
                icon: "sizzlejs_32x32.png"
            }
        ];

let project = projects.find((p) => {
    return p.value === 'jquery-ui';
});

project.desc = 'your value'

You should be able to do something like this:

For Docker* add this line:

RUN apt-get update && \
    apt-get install -y libxml2-dev && \
    docker-php-ext-install soap

*: For debian based images, ie. won't work for alpine variants.

From Django docs:

The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.

So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.

I'm a mathematician and I have seen and needed big-O O(n), big-Theta T(n), and big-Omega O(n) notation time and again, and not just for complexity of algorithms. As people said, big-Theta is a two-sided bound. Strictly speaking, you should use it when you want to explain that that is how well an algorithm can do, and that either that algorithm can't do better or that no algorithm can do better. For instance, if you say "Sorting requires T(n(log n)) comparisons for worst-case input", then you're explaining that there is a sorting algorithm that uses O(n(log n)) comparisons for any input; and that for every sorting algorithm, there is an input that forces it to make O(n(log n)) comparisons.

Now, one narrow reason that people use O instead of O is to drop disclaimers about worst or average cases. If you say "sorting requires O(n(log n)) comparisons", then the statement still holds true for favorable input. Another narrow reason is that even if one algorithm to do X takes time T(f(n)), another algorithm might do better, so you can only say that the complexity of X itself is O(f(n)).

However, there is a broader reason that people informally use O. At a human level, it's a pain to always make two-sided statements when the converse side is "obvious" from context. Since I'm a mathematician, I would ideally always be careful to say "I will take an umbrella if and only if it rains" or "I can juggle 4 balls but not 5", instead of "I will take an umbrella if it rains" or "I can juggle 4 balls". But the other halves of such statements are often obviously intended or obviously not intended. It's just human nature to be sloppy about the obvious. It's confusing to split hairs.

Unfortunately, in a rigorous area such as math or theory of algorithms, it's also confusing not to split hairs. People will inevitably say O when they should have said O or T. Skipping details because they're "obvious" always leads to misunderstandings. There is no solution for that.

I Reject Embedded JDK ( in 32bit ) because embedded JDK is 64bit

Right click your Project -> Open Module Setting -> SDK Location -> Uncheck Use embedded JDk then set your JDK Path, eg in Ubuntu /usr/lib/jvm/java-8-openjdk-i386

There is a slightly better way to access attached files. You could use template reference variable to get an instance of the input element.

Here is an example based on the first answer:

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="file" #file (change)="onChange(file.files)"/>
    </div>
  `,
  providers: [ UploadService ]
})

export class AppComponent {
  onChange(files) {
    console.log(files);
  }
}

Here is an example app to demonstrate this in action.

Template reference variables might be useful, e.g. you could access them via @ViewChild directly in the controller.

I might suggest 2 things.

1) If your query takes a lot of time because it´s using several tables that might involve locks, a quite fast solution is to run your queries with the "NoLock" hint.

Simply add Select * from YourTable WITH (NOLOCK) in all your table references an that will prevent your query to block for concurrent transactions.

2) if you want to be sure that all of your queries runs in (let´s say) less than 5 seconds, then you could add what @talha proposed, that worked sweet for me

Just add at the top of your execution

SET LOCK_TIMEOUT 5000;   --5 seconds.

And that will cause that your query takes less than 5 or fail. Then you should catch the exception and rollback if needed.

Hope it helps.

...and in case you wanted to link your main statically, in your Jamfile add the following to requirements:

<link>static
<library>/boost/system//boost_system

and perhaps also:

<linkflags>-static-libgcc
<linkflags>-static-libstdc++

The normal usage of static is to access the function directly with out any object creation. Same as in java main we could not create any object for that class to invoke the main method. It will execute automatically. If we want to execute manually we can call by using main() inside the class and ClassName.main from outside the class.

you can do it with Procedure also so i have a procedure for this

 DELIMITER $$
 CREATE PROCEDURE copyTo()
       BEGIN
               DECLARE x  INT;
            DECLARE str varchar(45);
              SET x = 1;
            set str = '';
              WHILE x < 5 DO
                set  str = (select source_col from emp where id=x);
            update emp set target_col =str where id=x;      
            SET  x = x + 1;
                END WHILE;

       END$$
   DELIMITER ;

I'd rather recommend you to use Volley to make GET, PUT, POST... requests.

First, add dependency in your gradle file.

compile 'com.he5ed.lib:volley:android-cts-5.1_r4'

Now, use this code snippet to make requests.

RequestQueue queue = Volley.newRequestQueue(getApplicationContext());

        StringRequest postRequest = new StringRequest( com.android.volley.Request.Method.POST, mURL,
                new Response.Listener<String>()
                {
                    @Override
                    public void onResponse(String response) {
                        // response
                        Log.d("Response", response);
                    }
                },
                new Response.ErrorListener()
                {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        // error
                        Log.d("Error.Response", error.toString());
                    }
                }
        ) {
            @Override
            protected Map<String, String> getParams()
            {
                Map<String, String>  params = new HashMap<String, String>();
                //add your parameters here as key-value pairs
                params.put("username", username);
                params.put("password", password);

                return params;
            }

        queue.add(postRequest);

From near the beginning of the PIL Tutorial:

Once you have an instance of the Image class, you can use the methods defined by this class to process and manipulate the image. For example, let's display the image we just loaded:

     >>> im.show()

Update:

Nowadays theImage.show() method is formally documented in the Pillow fork of PIL along with an explanation of how it's implemented on different OSs.

If you want more than just direct table grants (e.g., grants via roles, system privileges such as select any table, etc.), here are some additional queries:

System privileges for a user:

SELECT PRIVILEGE
  FROM sys.dba_sys_privs
 WHERE grantee = <theUser>
UNION
SELECT PRIVILEGE 
  FROM dba_role_privs rp JOIN role_sys_privs rsp ON (rp.granted_role = rsp.role)
 WHERE rp.grantee = <theUser>
 ORDER BY 1;

Direct grants to tables/views:

SELECT owner, table_name, select_priv, insert_priv, delete_priv, update_priv, references_priv, alter_priv, index_priv 
  FROM table_privileges
 WHERE grantee = <theUser>
 ORDER BY owner, table_name;

Indirect grants to tables/views:

SELECT DISTINCT owner, table_name, PRIVILEGE 
  FROM dba_role_privs rp JOIN role_tab_privs rtp ON (rp.granted_role = rtp.role)
 WHERE rp.grantee = <theUser>
 ORDER BY owner, table_name;

With bash:

Create an array of entries with ( ) and get the count with #.

FILES=(./*); echo ${#FILES[@]}

Ok that doesn't recursively count files but I wanted to show the simple option first. A common use case might be for creating rollover backups of a file. This will create logfile.1, logfile.2, logfile.3 etc.

CNT=(./logfile*); mv logfile logfile.${#CNT[@]}

Recursive count with bash 4+ globstar enabled (as mentioned by @tripleee)

FILES=(**/*); echo ${#FILES[@]}

To get the count of files recursively we can still use find in the same way.

FILES=(`find . -type f`); echo ${#FILES[@]}

All you need to do is change the string within the java.text.SimpleDateFormat constructor to: "MM-dd-yyyy HH:mm:ss".

Just use the appropriate letters to build the above string to match your input date.

onSaveInstance will be called if a user rotates the screen so that it can load resources associated with the new orientation.

It's possible that this user rotated the screen followed by pressing the back button (because it's also possible that this user fumbled their phone while using your app)

Worth noting that when you inspect a string using the interactive python shell or a Jupyter notebook, the \n and other backslashed strings like \t are rendered literally:

>>> gotcha = 'Here is some random message...'
>>> gotcha += '\nAdditional content:\n\t{}'.format('Yet even more great stuff!')
>>> gotcha
'Here is some random message...\nAdditional content:\n\tYet even more great stuff!'

The newlines, tabs, and other special non-printed characters are rendered as whitespace only when printed, or written to a file:

>>> print('{}'.format(gotcha))
Here is some random message...
Additional content:
    Yet even more great stuff!

It could be built with easiest way:

Alert Dialog with Custom View and with two Buttons (Positive & Negative).

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()).setTitle(getString(R.string.select_period));
builder.setPositiveButton(getString(R.string.ok), null);

 builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    // Click of Cancel Button

   }
 });

  LayoutInflater li = LayoutInflater.from(getActivity());
  View promptsView = li.inflate(R.layout.dialog_date_picker, null, false);
  builder.setView(promptsView);

  DatePicker startDatePicker = (DatePicker)promptsView.findViewById(R.id.startDatePicker);
  DatePicker endDatePicker = (DatePicker)promptsView.findViewById(R.id.endDatePicker);

  final AlertDialog alertDialog = builder.create();
  alertDialog.show();

  Button theButton = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
  theButton.setOnClickListener(new CustomListener(alertDialog, startDatePicker, endDatePicker));

CustomClickLister of Positive Button of Alert Dailog:

private class CustomListener implements View.OnClickListener {
        private final Dialog dialog;
        private DatePicker mStartDp, mEndDp;
    public CustomListener(Dialog dialog, DatePicker dS, DatePicker dE) {
        this.dialog = dialog;
        mStartDp = dS;
        mEndDp = dE;
    }

    @Override
    public void onClick(View v) {

        int day1  = mStartDp.getDayOfMonth();
        int month1= mStartDp.getMonth();
        int year1 = mStartDp.getYear();
        Calendar cal1 = Calendar.getInstance();
        cal1.set(Calendar.YEAR, year1);
        cal1.set(Calendar.MONTH, month1);
        cal1.set(Calendar.DAY_OF_MONTH, day1);


        int day2  = mEndDp.getDayOfMonth();
        int month2= mEndDp.getMonth();
        int year2 = mEndDp.getYear();
        Calendar cal2 = Calendar.getInstance();
        cal2.set(Calendar.YEAR, year2);
        cal2.set(Calendar.MONTH, month2);
        cal2.set(Calendar.DAY_OF_MONTH, day2);

        if(cal2.getTimeInMillis()>=cal1.getTimeInMillis()){
            dialog.dismiss();
            Log.i("Dialog", "Dismiss");
            // Condition is satisfied so do dialog dismiss
            }else {
            Log.i("Dialog", "Do not Dismiss");
            // Condition is not satisfied so do not dialog dismiss
        }

    }
}

Done

You can achieve this with the background-size property, which is now supported by most browsers.

To scale the background image to fit inside the div:

background-size: contain;

To scale the background image to cover the whole div:

background-size: cover;

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

make sure the database you want to import to is created, then you can import the dump with

sudo -u postgres -i psql testdatabase < db-structure.sql

If you want to overwrite the whole database, first drop the database

# be sure you drop the right database !!!
#sudo -u postgres -i psql -c "drop database testdatabase;"

and then recreate it with

sudo -u postgres -i psql -c "create database testdatabase;"

Sorry not sure what was going on this worked in the end:

You can fill a hidden field from your JavaScript code and do an explicit postback from JavaScript. Then from the server side, check that hiddenfield and do whatever necessary.

This will work if you are not blocking.

If you are planing on doing sleeps, its absolutely imperative that you use the event to do the sleep. If you leverage the event to sleep, if someone tells you to stop while "sleeping" it will wake up. If you use time.sleep() your thread will only stop after it wakes up.

import threading
import time

duration = 2

def main():
    t1_stop = threading.Event()
    t1 = threading.Thread(target=thread1, args=(1, t1_stop))

    t2_stop = threading.Event()
    t2 = threading.Thread(target=thread2, args=(2, t2_stop))

    time.sleep(duration)
    # stops thread t2
    t2_stop.set()

def thread1(arg1, stop_event):
    while not stop_event.is_set():
        stop_event.wait(timeout=5)

def thread2(arg1, stop_event):
    while not stop_event.is_set():
        stop_event.wait(timeout=5)

i got the same problem and i notice that my security config has diferent TAGS like the @Xenolion answer says

<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </domain-config>
</network-security-config>

so i change the TAGS "domain-config" for "base-config" and works, like this:

<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </base-config>
</network-security-config>

There are 2 issues with your code:

1. The result is stored in int which can handle only a first 48 fibonacci numbers, after this the integer fill minus bit and result is wrong.
2. But you never can run fibonacci(50).
   The code
   fibonacci(n - 1) + fibonacci(n - 2)
   is very wrong.
   The problem is that the it calls fibonacci not 50 times but much more.
   At first it calls fibonacci(49)+fibonacci(48),
   next fibonacci(48)+fibonacci(47) and fibonacci(47)+fibonacci(46)
   Each time it became fibonacci(n) worse, so the complexity is exponential.

The approach to non-recursive code:

 double fibbonaci(int n){
    double prev=0d, next=1d, result=0d;
    for (int i = 0; i < n; i++) {
        result=prev+next;
        prev=next;
        next=result;
    }
    return result;
}

This is what I ended up using inside my .bat file. Windows only of course.

set CURRENT_DIR=%cd%
mkdir ./directoryToExtractTo
cd ./directoryToExtractTo
jar xvf %CURRENT_DIR%\myJar.jar
cd %CURRENT_DIR%

Passing data from one Activity to Activity in android

An intent contains the action and optionally additional data. The data can be passed to other activity using intent putExtra() method. Data is passed as extras and are key/value pairs. The key is always a String. As value you can use the primitive data types int, float, chars, etc. We can also pass Parceable and Serializable objects from one activity to other.

Intent intent = new Intent(context, YourActivity.class);
intent.putExtra(KEY, <your value here>);
startActivity(intent);

Retrieving bundle data from android activity

You can retrieve the information using getData() methods on the Intent object. The Intent object can be retrieved via the getIntent() method.

 Intent intent = getIntent();
  if (null != intent) { //Null Checking
    String StrData= intent.getStringExtra(KEY);
    int NoOfData = intent.getIntExtra(KEY, defaultValue);
    boolean booleanData = intent.getBooleanExtra(KEY, defaultValue);
    char charData = intent.getCharExtra(KEY, defaultValue); 
  }

<input type="checkbox" name="check1" value="checkbox" onchange="showMe('div1')" /> checkbox

<div id="div1" style="display:none;">NOTICE</div>

  <script type="text/javascript">
<!--
   function showMe (box) {
    var chboxs = document.getElementById("div1").style.display;
    var vis = "none";
        if(chboxs=="none"){
         vis = "block"; }
        if(chboxs=="block"){
         vis = "none"; }
    document.getElementById(box).style.display = vis;
}
  //-->
</script>

There are two ways to implement this:

1.

    $date = strtotime(date);
    $new_date = date('d-m-Y', $date);

2.

    $cls_date = new DateTime($date);
    echo $cls_date->format('d-m-Y');

As an answer strictly in line with your question, I support cleytus's proposal.

You could also use a marker interface (with no method), say DistantCall, with several several sub-interfaces that have the precise signatures you want.

• The general interface would serve to mark all of them, in case you want to write some generic code for all of them.
• The number of specific interfaces can be reduced by using cleytus's generic signature.

Examples of 'reusable' interfaces:

    public interface DistantCall {
    }

    public interface TUDistantCall<T,U> extends DistantCall {
      T execute(U... us);
    }

    public interface UDistantCall<U> extends DistantCall {
      void execute(U... us);
    }

    public interface TDistantCall<T> extends DistantCall {
      T execute();
    }

    public interface TUVDistantCall<T, U, V> extends DistantCall {
      T execute(U u, V... vs);
    }
    ....

UPDATED in response to OP comment

I wasn't thinking of any instanceof in the calling. I was thinking your calling code knew what it was calling, and you just needed to assemble several distant call in a common interface for some generic code (for example, auditing all distant calls, for performance reasons). In your question, I have seen no mention that the calling code is generic :-(

If so, I suggest you have only one interface, only one signature. Having several would only bring more complexity, for nothing.

However, you need to ask yourself some broader questions :
how you will ensure that caller and callee do communicate correctly?

That could be a follow-up on this question, or a different question...

If you want to hide just the axis text keeping the grid lines:

frame1 = plt.gca()
frame1.axes.xaxis.set_ticklabels([])
frame1.axes.yaxis.set_ticklabels([])

Doing set_visible(False) or set_ticks([]) will also hide the grid lines.

string St = String.Format("{0,-20} {1,5:N1}\r", names[ctr], hours[ctr]);
richTextBox1.Text += St;

This works well, but you must have a mono-spaced font.

This is how I solved it based on this post with some minor tweaks. This solution does not require creation of any additional classes.

SSLContext sc = SSLContext.getInstance("SSLv3");

KeyManagerFactory kmf =
    KeyManagerFactory.getInstance( KeyManagerFactory.getDefaultAlgorithm() );

KeyStore ks = KeyStore.getInstance( KeyStore.getDefaultType() );
ks.load(new FileInputStream( certPath ), certPasswd.toCharArray() );

kmf.init( ks, certPasswd.toCharArray() );

sc.init( kmf.getKeyManagers(), null, null );

((BindingProvider) webservicePort).getRequestContext()
    .put(
        "com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory",
        sc.getSocketFactory() );

Dynamitey is an open source .net std library, that let's you call it like the dynamic keyword, but using the a string for the property name rather than the compiler doing it for you, and it ends up being equal to reflection speedwise (which is not nearly as fast as using the dynamic keyword, but this is due to the extra overhead of caching dynamically, where the compiler caches statically).

Dynamic.InvokeGet(d,"value2");

Another option is to use the Apache Maven Shade Plugin: This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies.

add this to your build plugins section

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-shade-plugin</artifactId>
</plugin>

A simple but dirty trick is to simply add the offset you want to the image you are using as background. it's not maintainable, but it gets the job done.

The problem is that, even in 2014, devices handle screen resize events, as well as scroll events, inconsistently while the soft keyboard is open.

I've found that, even if you're using a bluetooth keyboard, iOS in particular triggers some strange layout bugs; so instead of detecting a soft keyboard, I've just had to target devices that are very narrow and have touchscreens.

I use media queries (or window.matchMedia) for width detection and Modernizr for touch event detection.

I've seen a lot of variation in answers for how to do this, so I thought I'd summarize them here (plus add a 4th method of my own invention):

(1) Add a unique cache-busting query parameter to the URL, such as:

newImage.src = "image.jpg?t=" + new Date().getTime();

Pros: 100% reliable, quick & easy to understand and implement.

Cons: Bypasses caching altogether, meaning unnecessary delays and bandwidth use whenever the image doesn't change between views. Will potentially fill browser cache (and any intermediate caches) with many, many copies of exactly the same image! Also, requires modifying image URL.

When to use: Use when image is constantly changing, such as for a live webcam feed. If you use this method, make sure to serve the images themselves with Cache-control: no-cache HTTP headers!!! (Often this can be set up using a .htaccess file). Otherwise you'll be progressively filling caches up with old versions of the image!

(2) Add query parameter to the URL that changes only when the file does, e.g.:

echo '<img src="image.jpg?m=' . filemtime('image.jpg') . '">';

(That's PHP server-side code, but the important point here is just that a ?m=[file last-modified time] querystring is appended to the filename).

Pros: 100% reliable, quick & easy to understand and implement, and preserves caching advantages perfectly.

Cons: Requires modifying the image URL. Also, a little more work for the server - it has to get access to the file-last-modified time. Also, requires server-side information, so not suitable for a purely client-side-only solution to check for a refreshed image.

When to use: When you want to cache images, but may need to update them at the server end from time to time without changing the filename itself. AND when you can easily ensure that the correct querystring is added to every image instance in your HTML.

(3) Serve your images with the header Cache-control: max-age=0, must-revalidate, and add a unique memcache-busting fragment identifier to the URL, such as:

newImage.src = "image.jpg#" + new Date().getTime();

The idea here is that the cache-control header puts images in the browser cache, but immediately markes them stale, so that and every time they are re-displayed the browser must check with the server to see if they've changed. This ensures that the browser's HTTP cache always returns the latest copy of the image. However, browsers will often re-use an in-memory copy of an image if they have one, and not even check their HTTP cache in that case. To prevent this, a fragment identifier is used: Comparison of in-memory image src's includes the fragment identifier, but it gets stripped of before querying the HTTP cache. (So, e.g., image.jpg#A and image.jpg#B might both be displayed from the image.jpg entry in the browser's HTTP cache, but image.jpg#B would never be displayed using in-memory retained image data from when image.jpg#A was last displayed).

Pros: Makes proper use of HTTP caching mechanisms, and uses cached images if they haven't changed. Works for servers that choke on a querystring added to a static image URL (since servers never see fragment identifiers - they're for the browsers' own use only).

Cons: Relies on somewhat dubious (or at least poorly documented) behaviour of browsers, in regard to images with fragment identifiers in their URLs (However, I've tested this successfully in FF27, Chrome33, and IE11). Does still send a revalidation request to the server for every image view, which may be overkill if images only change rarely and/or latency is a big issue (since you need to wait for the revalidation response even when the cached image is still good). Requires modifying image URLs.

When to use: Use when images may change frequently, or need to be refreshed intermittently by the client without server-side script involvement, but where you still want the advantage of caching. For example, polling a live webcam that updates an image irregularly every few minutes. Alternatively, use instead of (1) or (2) if your server doesn't allow querystrings on static image URLs.

(4) Forcibly refresh a particular image using Javascript, by first loading it into a hidden <iframe> and then calling location.reload(true) on the iframe's contentWindow.

The steps are:

• Load the image to be refreshed into a hidden iframe. This is just a setup step - it can be done long in advance the actual refresh, if desired. It doesn't even matter if the image fails to load at this stage!

• Once that's done, blank out all copies of that image on your page(s) or anywhere in any DOM nodes (even off-page ones stored in javascript variables). This is necessary because the browser may otherwise display the image from a stale in-memory copy (IE11 especially does this): You need to ensure all in-memory copies are cleared, before refreshing the HTTP cache. If other javascript code is running asynchronously, you may also need to prevent that code from creating new copies of the to-be-refreshed image in the meantime.

• Call iframe.contentWindow.location.reload(true). The true forces a cache bypass, reloading directly from the server and overwriting the existing cached copy.

• Once it's finished re-loading, restore the blanked images. They should now display the fresh version from the server!

For same-domain images, you can load the image into the iframe directly. For cross-domain images, you have to instead load a HTML page from your domain that contains the image in an <img> tag, otherwise you'll get an "Access Denied" error when trying to call iframe.contentWindow.reload(...).

Pros: Works just like the image.reload() function you wish the DOM had! Allows images to by cached normally (even with in-the-future expiry dates if you want them, thus avoiding frequent revalidation). Allows you to refresh a particular image without altering the URLs for that image on the current page, or on any other pages, using only client-side code.

Cons: Relies on Javascript. Not 100% guaranteed to work properly in every browser (I've tested this successfully in FF27, Chrome33, and IE11 though). Very complicated relative to the other methods.

When to use: When you have a collection of basically static images that you'd like cached, but you still need to be able to update them occasionally and get immediate visual feedback that the update took place. (Especially when just refreshing the whole browser page wouldn't work, as in some web apps built on AJAX for example). And when methods (1)-(3) aren't feasible because (for whatever reason) you can't change all the URLs that might potentially display the image you need to have updated. (Note that using those 3 methods the image will be refreshed, but if another page then tries to displays that image without the appropriate querystring or fragment identifier, it may show an older version instead).

The details of implementing this in a fairy robust and flexible manner are given below:

Let's assume your website contains a blank 1x1 pixel .gif at the URL path /img/1x1blank.gif, and also has the following one-line PHP script (only required for applying forced refresh to cross-domain images, and can be rewritten in any server-side scripting language, of course) at the URL path /echoimg.php:

<img src="<?=htmlspecialchars(@$_GET['src'],ENT_COMPAT|ENT_HTML5,'UTF-8')?>">

Then, here's a realistic implementation of how you might do all this in Javascript. It looks a bit complicated, but there's a lot of comments, and the important function is just forceImgReload() - the first two just blank and un-blank images, and should be designed to work efficiently with your own HTML, so code them as works best for you; much of the complications in them may be unnecessary for your website:

// This function should blank all images that have a matching src, by changing their src property to /img/1x1blank.gif.
// ##### You should code the actual contents of this function according to your page design, and what images there are on them!!! #####
// Optionally it may return an array (or other collection or data structure) of those images affected.
// This can be used by imgReloadRestore() to restore them later, if that's an efficient way of doing it (otherwise, you don't need to return anything).
// NOTE that the src argument here is just passed on from forceImgReload(), and MAY be a relative URI;
// However, be aware that if you're reading the src property of an <img> DOM object, you'll always get back a fully-qualified URI,
// even if the src attribute was a relative one in the original HTML.  So watch out if trying to compare the two!
// NOTE that if your page design makes it more efficient to obtain (say) an image id or list of ids (of identical images) *first*, and only then get the image src,
// you can pass this id or list data to forceImgReload() along with (or instead of) a src argument: just add an extra or replacement parameter for this information to
// this function, to imgReloadRestore(), to forceImgReload(), and to the anonymous function returned by forceImgReload() (and make it overwrite the earlier parameter variable from forceImgReload() if truthy), as appropriate.
function imgReloadBlank(src)
{
  // ##### Everything here is provisional on the way the pages are designed, and what images they contain; what follows is for example purposes only!
  // ##### For really simple pages containing just a single image that's always the one being refreshed, this function could be as simple as just the one line:
  // ##### document.getElementById("myImage").src = "/img/1x1blank.gif";

  var blankList = [],
      fullSrc = /* Fully qualified (absolute) src - i.e. prepend protocol, server/domain, and path if not present in src */,
      imgs, img, i;

  for each (/* window accessible from this one, i.e. this window, and child frames/iframes, the parent window, anything opened via window.open(), and anything recursively reachable from there */)
  {
    // get list of matching images:
    imgs = theWindow.document.body.getElementsByTagName("img");
    for (i = imgs.length; i--;) if ((img = imgs[i]).src===fullSrc)  // could instead use body.querySelectorAll(), to check both tag name and src attribute, which would probably be more efficient, where supported
    {
      img.src = "/img/1x1blank.gif";  // blank them
      blankList.push(img);            // optionally, save list of blanked images to make restoring easy later on
    }
  }

  for each (/* img DOM node held only by javascript, for example in any image-caching script */) if (img.src===fullSrc)
  {
    img.src = "/img/1x1blank.gif";   // do the same as for on-page images!
    blankList.push(img);
  }

  // ##### If necessary, do something here that tells all accessible windows not to create any *new* images with src===fullSrc, until further notice,
  // ##### (or perhaps to create them initially blank instead and add them to blankList).
  // ##### For example, you might have (say) a global object window.top.blankedSrces as a propery of your topmost window, initially set = {}.  Then you could do:
  // #####
  // #####     var bs = window.top.blankedSrces;
  // #####     if (bs.hasOwnProperty(src)) bs[src]++; else bs[src] = 1;
  // #####
  // ##### And before creating a new image using javascript, you'd first ensure that (blankedSrces.hasOwnProperty(src)) was false...
  // ##### Note that incrementing a counter here rather than just setting a flag allows for the possibility that multiple forced-reloads of the same image are underway at once, or are overlapping.

  return blankList;   // optional - only if using blankList for restoring back the blanked images!  This just gets passed in to imgReloadRestore(), it isn't used otherwise.
}

function forceImgReload(src, isCrossDomain, imgDim, twostage)
{
  var blankList, step = 0,                                // step: 0 - started initial load, 1 - wait before proceeding (twostage mode only), 2 - started forced reload, 3 - cancelled

        {

          if (iframe.contentWindow.stop) iframe.contentWindow.stop();
          if (iframe.parentNode) iframe.parentNode.removeChild(iframe);
        }
      }
    : null);
}

Then, to force a refresh of an image located on the same domain as your page, you can just do:

forceImgReload("myimage.jpg");

To refresh an image from somewhere else (cross-domain):

forceImgReload("http://someother.server.com/someimage.jpg", true);

A more advanced application might be to reload an image after uploading a new version to your server, preparing the initial stage of the reload process simultaneous with the upload, to minimize the visible reload delay to the user. If you're doing the upload via AJAX, and the server is returning a very simple JSON array [success, width, height] then your code might look something like this:

// fileForm is a reference to the form that has a the <input typ="file"> on it, for uploading.
// serverURL is the url at which the uploaded image will be accessible from, once uploaded.
// The response from uploadImageToServer.php is a JSON array [success, width, height]. (A boolean and two ints).
function uploadAndRefreshCache(fileForm, serverURL)
{
  var xhr = new XMLHttpRequest(),
      proceedWithImageRefresh = forceImgReload(serverURL, false, null, true);
  xhr.addEventListener("load", function(){ var arr = JSON.parse(xhr.responseText); if (!(arr&&arr[0])) { proceedWithImageRefresh(false); doSomethingOnUploadFailure(...); } else { proceedWithImageRefresh(true,[arr[1],ar[2]]); doSomethingOnUploadSuccess(...); }});
  xhr.addEventListener("error", function(){ proceedWithImageRefresh(false); doSomethingOnUploadError(...); });
  xhr.addEventListener("abort", function(){ proceedWithImageRefresh(false); doSomethingOnUploadAborted(...); });
  // add additional event listener(s) to track upload progress for graphical progress bar, etc...
  xhr.open("post","uploadImageToServer.php");
  xhr.send(new FormData(fileForm));
}

A final note: Although this topic is about images, it potentially applies to other kinds of files or resources also. For example, preventing the use of stale script or css files, or perhaps even refreshing updated PDF documents (using (4) only if set up to open in-browser). Method (4) might require some changes to the above javascript, in these cases.

That's not true Jeff.

You simply have to select a folder within your IIS 7 Manager UI (e.g. Images or event the Default Web Application folder) and then click on "HTTP Response Headers". Then you have to click on "Set Common Header.." in the right pane and select the "Expire Web content". There you can easily configure a max-age of 24 hours by choosing "After:", entering "24" in the Textbox and choose "Hours" in the combobox.

Your first paragraph regarding the web.config entry is right. I'd add the cacheControlCustom-attribute to set the cache control header to "public" or whatever is needed in that case.

You can, of course, achieve the same by providing web.config entries (or files) as needed.

Edit: removed a confusing sentence :)

The C language does not support pass by reference of any type. The closest equivalent is to pass a pointer to the type.

Here is a contrived example in both languages

C++ style API

void UpdateValue(int& i) {
  i = 42;
}

Closest C equivalent

void UpdateValue(int *i) {
  *i = 42;
}

It's easy

    // MARK: - Gradient

        case bottomLeft
        case topCenter
        case center
        case bottomCenter
        case topRight
        case centerRight
        case bottomRight
        var point: CGPoint {
            switch self {
            case .topLeft:
                return CGPoint(x: 0, y: 0)

        self.colors = colors
        self.locations = (0..<colors.count).map(NSNumber.init)

Use like this:-

let fistColor = UIColor.white
let lastColor = UIColor.black
let gradient = CAGradientLayer(start: .topLeft, end: .topRight, colors: [fistColor.cgColor, lastColor.cgColor], type: .radial)
gradient.frame = yourView.bounds
yourView.layer.addSublayer(gradient)

Usually when I get these kinds of errors, opening the __init__.py file and poking around helps. Go to the directory C:\Python27\lib\site-packages\sklearn and ensure that there's a sub-directory called __check_build as a first step. On my machine (with a working sklearn installation, Mac OSX, Python 2.7.3) I have __init__.py, setup.py, their associated .pyc files, and a binary _check_build.so.

Poking around the __init__.py in that directory, the next step I'd take is to go to sklearn/__init__.py and comment out the import statement---the check_build stuff just checks that things were compiled correctly, it doesn't appear to do anything but call a precompiled binary. This is, of course, at your own risk, and (to be sure) a work around. If your build failed you'll likely soon run into other, bigger problems.

You can use the length() method on File which returns the size in bytes.

You can use .addAll() to add the elements of the second list to the first:

array1.addAll(array2);

Edit: Based on your clarification above ("i want a single String in the new Arraylist which has both name and number."), you would want to loop through the first list and append the item from the second list to it.

Something like this:

int length = array1.size();
if (length != array2.size()) { // Too many names, or too many numbers
    // Fail
}
ArrayList<String> array3 = new ArrayList<String>(length); // Make a new list
for (int i = 0; i < length; i++) { // Loop through every name/phone number combo
    array3.add(array1.get(i) + " " + array2.get(i)); // Concat the two, and add it
}

If you put in:

array1 : ["a", "b", "c"]
array2 : ["1", "2", "3"]

You will get:

array3 : ["a 1", "b 2", "c 3"]

By default, you should be able to toggle the Internet access to your emulator with F8 (on Windows) and Fn + F8 (on Mac OS X) - I think F8 also works for Linux, but I'm not 100% sure.

With this shortcut, you get the ACTION_BACKGROUND_DATA_SETTING_CHANGED dispatched.

Hope that helps.

Step 1: Add the bean class into the dataFormat list:

<dataFormats>
    <json id="jack" library="Jackson" prettyPrint="true"
          unmarshalTypeName="{ur bean class path}" /> 
</dataFormats>

Step 2: Marshal the bean prior to the client call:

<marchal id="marsh" ref="jack"/>

If the above doesn't work for you, try this:

.btn:focus {outline: none;box-shadow: none;border:2px solid transparent;}

As user1933897 pointed out, this might be specific to MacOS with Chrome.

I faced the same issue in my scenario as follow:

I created textbook table first with

create table textbook(txtbk_isbn varchar2(13)
primary key,txtbk_title varchar2(40),
txtbk_author varchar2(40) );

Then chapter table:

create table chapter(txtbk_isbn varchar2(13),chapter_title varchar2(40), constraint pk_chapter primary key(txtbk_isbn,chapter_title), constraint chapter_txtbook foreign key (txtbk_isbn) references textbook (txtbk_isbn));

Then topic table:

create table topic(topic_id varchar2(20) primary key,topic_name varchar2(40));

Now when I wanted to create a relationship called chapter_topic between chapter (having composite primary key) and topic (having single column primary key), I faced issue with following query:

create table chapter_topic(txtbk_isbn varchar2(13),chapter_title varchar2(40),topic_id varchar2(20), primary key (txtbk_isbn, chapter_title, topic_id), foreign key (txtbk_isbn) references textbook(txtbk_isbn), foreign key (chapter_title) references chapter(chapter_title), foreign key (topic_id) references topic (topic_id));

The solution was to refer to composite foreign key as below:

create table chapter_topic(txtbk_isbn varchar2(13),chapter_title varchar2(40),topic_id varchar2(20), primary key (txtbk_isbn, chapter_title, topic_id), foreign key (txtbk_isbn, chapter_title) references chapter(txtbk_isbn, chapter_title), foreign key (topic_id) references topic (topic_id));

Thanks to APC post in which he mentioned in his post a statement that:

Common reasons for this are
- the parent lacks a constraint altogether
- the parent table's constraint is a compound key and we haven't referenced all the columns in the foreign key statement.
- the referenced PK constraint exists but is DISABLED

You are not returning a response object from your view my_form_post. The function ends with implicit return None, which Flask does not like.

Make the function my_form_post return an explicit response, for example

return 'OK'

at the end of the function.

I had same problem. Try the following command. This solved my problem.

sudo apt-get install libapache2-mod-php5

Remove the last characters from a string

TXTB_DateofReiumbursement.Text = (gvFinance.SelectedRow.FindControl("lblDate_of_Reimbursement") as Label).Text.Remove(10)

.Text.Remove(10)// used to remove text starting from index 10 to end

This helped me get close to what I needed and I will throw this out there for anyone else who needs it.

If you are looking for the value in the first cell in the selected column, you can try this. (I chose the first column, since you are asking for it to return "3", but you can change the number after Cells to get whichever column you need. Remember it is zero-based.)

This will copy the result to the clipboard: Clipboard.SetDataObject(Me.DataGridView1.CurrentRow.Cells(0).Value)

The fluent way:

public static String fileNameWithOutExt (String fileName) {
    return Optional.of(fileName.lastIndexOf(".")).filter(i-> i >= 0)
            .map(i-> fileName.substring(0, i)).orElse(fileName);
}

You can also change the data type to bigInt and it will solve your problem, it's not a good practice to keep integers as strings unless needed. :)

ALTER TABLE T_PERSON MODIFY mobile_no BIGINT;

You can stop the image from overlapping it's edges by clipping the image and applying a wrapper element which sets the blur effect to 0 pixels. This is how it looks like:

HTML

<div id="wrapper">
  <div id="image"></div>
</div>

CSS

#wrapper {
  width: 1024px;
  height: 768px;

  border: 1px solid black;

  // 'blur(0px)' will prevent the wrapped image
  // from overlapping the border
  -webkit-filter: blur(0px);
  -moz-filter: blur(0px);
  -ms-filter: blur(0px);
  filter: blur(0px);
}

#wrapper #image {
  width: 1024px;
  height: 768px;

  background-image: url("../images/cats.jpg");
  background-size: cover;

  -webkit-filter: blur(10px);
  -moz-filter: blur(10px);
  -ms-filter: blur(10px);
  filter: blur(10px);

  // Position 'absolute' is needed for clipping
  position: absolute;
  clip: rect(0px, 1024px, 768px, 0px);
}

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.

In your case, this should work:

<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">

This is happening because there is an unhandled exception in your Web service, and the .NET runtime is spitting out its HTML yellow screen of death server error/exception dump page, instead of XML.

Since the consumer of your Web service was expecting a text/xml header and instead got text/html, it throws that error.

You should address the cause of your timeouts (perhaps a lengthy SQL query?).

Also, checkout this blog post on Jeff Atwood's blog that explains implementing a global unhandled exception handler and using SOAP exceptions.

Try like this;

Uri.GetLeftPart( UriPartial.Authority )

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

Check out this plugin:

moment-countdown

moment-countdown is a tiny moment.js plugin that integrates with Countdown.js. The file is here.

How it works?

//from then until now
moment("1982-5-25").countdown().toString(); //=> '30 years, 10 months, 14 days, 1 hour, 8 minutes, and 14 seconds'

//accepts a moment, JS Date, or anything parsable by the Date constructor
moment("1955-8-21").countdown("1982-5-25").toString(); //=> '26 years, 9 months, and 4 days'

//also works with the args flipped, like diff()
moment("1982-5-25").countdown("1955-8-21").toString(); //=> '26 years, 9 months, and 4 days'

//accepts all of countdown's options
moment().countdown("1982-5-25", countdown.MONTHS|countdown.WEEKS, NaN, 2).toString(); //=> '370 months, and 2.01 weeks'

A few years late, but here is another alternative.

For x = LBound(arr) To UBound(arr)
    sname = arr(x)  
    If InStr(sname, "Configuration item") Then  
        'Do nothing here, which automatically go to the next iteration
    Else
        'Code to perform the required action
    End If
Next x

Solved the issue for me :

    Range(Cells(1, 1), Cells(100, 1)).Select

    For Each xCell In Selection

    xCell.Value = CDate(xCell.Value)

    Next xCell

A quick search of the docs for the ListView class has turned up getChildCount() and getChildAt() methods inherited from ViewGroup. Can you iterate through them using these? I'm not sure but it's worth a try.

Found it here

Note: With ConcurrentMap you can use the more efficient

values.putIfAbsent(NoteColumns.CREATED_DATE, now);

I prefer the less verbose solution and avoid methods like IsTrue or IsFalse or their like.

Since it is in the directory data/, You need to do:

file path is '../../data/file.json'

$.getJSON('../../data/file.json', function(data) {         
    alert(data);
});

Pure JS:

   var request = new XMLHttpRequest();
   request.open("GET", "../../data/file.json", false);
   request.send(null)
   var my_JSON_object = JSON.parse(request.responseText);
   alert (my_JSON_object.result[0]);

the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)

=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679

So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)

In addition to the ioctl() method Filip demonstrated you can use getifaddrs(). There is an example program at the bottom of the man page.

The steel is far from hot, but I combined @abatishchev's solution with the answer from this post and got to this result. Hope it's useful:

public static class GlobalVars
{
    private const string GlobalKey = "AllMyVars";

    static GlobalVars()
    {
        Hashtable table = HttpContext.Current.Application[GlobalKey] as Hashtable;

        if (table == null)
        {
            table = new Hashtable();
            HttpContext.Current.Application[GlobalKey] = table;
        }
    }

    public static Hashtable Vars
    {
        get { return HttpContext.Current.Application[GlobalKey] as Hashtable; }
    }

    public static IEnumerable<SomeClass> SomeCollection
    {
        get { return GetVar("SomeCollection") as IEnumerable<SomeClass>; }
        set { WriteVar("SomeCollection", value); }
    }

    internal static DateTime SomeDate
    {
        get { return (DateTime)GetVar("SomeDate"); }
        set { WriteVar("SomeDate", value); }
    }

    private static object GetVar(string varName)
    {
        if (Vars.ContainsKey(varName))
        {
            return Vars[varName];
        }

        return null;
    }

    private static void WriteVar(string varName, object value)
    {
        if (value == null)
        {
            if (Vars.ContainsKey(varName))
            {
                Vars.Remove(varName);
            }
            return;
        }

        if (Vars[varName] == null)
        {
            Vars.Add(varName, value);
        }
        else

Building off some of the good answers already given, here is a purely Storyboard / Interface Builder-based solution that works in iOS 7.0+

Set the UITextView's User Defined Runtime Attributes for the following keys:

textContainer.lineFragmentPadding
textContainerInset

The syntax for find in mongodb is

    db.<collection name>.find(query, projection);

and the second query that you have written, that is

    db.test.find(
    {shapes: {"$elemMatch": {color: "red"}}}, 
    {"shapes.color":1})

in this you have used the $elemMatch operator in query part, whereas if you use this operator in the projection part then you will get the desired result. You can write down your query as

     db.users.find(
     {"shapes.color":"red"},
     {_id:0, shapes: {$elemMatch : {color: "red"}}})

This will give you the desired result.

This should work.

app = angular.module('plunker', [])

app.controller 'MainCtrl', ($scope) ->
  $scope.users = ['bob', 'sean', 'rocky', 'john']
  $scope.test = ->
    console.log $scope.users

HTML:

<input ng-repeat="user in users" ng-model="user" type="text"/>
<input type="button" value="test" ng-click="test()" />

To omit all falsey values but keep the boolean primitives this solution helps.

_.omitBy(fields, v => (_.isBoolean(v)||_.isFinite(v)) ? false : _.isEmpty(v));

let fields = {_x000D_
str: 'CAD',_x000D_
numberStr: '123',_x000D_
number  : 123,_x000D_
boolStrT: 'true',_x000D_
boolStrF: 'false',_x000D_
boolFalse : false,_x000D_
boolTrue  : true,_x000D_
undef: undefined,_x000D_
nul: null,_x000D_
emptyStr: '',_x000D_
array: [1,2,3],_x000D_
emptyArr: []_x000D_
};_x000D_
_x000D_
let nobj = _.omitBy(fields, v => (_.isBoolean(v)||_.isFinite(v)) ? false : _.isEmpty(v));_x000D_
_x000D_
console.log(nobj);

Drag & Drop

To install apk in avd, just manually drag and drop the apk file in the opened emulated device

The same if you want to copy a file to the sd card

<parent>
    <groupId>com.dummy.bla</groupId>
    <artifactId>parent</artifactId>
    <version>0.1-SNAPSHOT</version>     
 </parent>

 <groupId>com.dummy.bla.sub</groupId>
 <artifactId>kid</artifactId>

You mean you want to remove the version from parent block of B's pom, I think you can not do it, the groupId, artifactId, and version specified the parent's pom coordinate's, what you can omit is child's version.

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

Check that your templates.html are in /usr/lib/python2.5/site-packages/projectname/templates dir.

Python has the syntactical requirement that code blocks (after if, except, def, class etc.) cannot be empty. Empty code blocks are however useful in a variety of different contexts, such as in examples below, which are the most frequent use cases I have seen.

Therefore, if nothing is supposed to happen in a code block, a pass is needed for such a block to not produce an IndentationError. Alternatively, any statement (including just a term to be evaluated, like the Ellipsis literal ... or a string, most often a docstring) can be used, but the pass makes clear that indeed nothing is supposed to happen, and does not need to be actually evaluated and (at least temporarily) stored in memory.

• Ignoring (all or) a certain type of Exception (example from xml):

  try:
      self.version = "Expat %d.%d.%d" % expat.version_info
  except AttributeError:
      pass # unknown
  

  Note: Ignoring all types of raises, as in the following example from pandas, is generally considered bad practice, because it also catches exceptions that should probably be passed on to the caller, e.g. KeyboardInterrupt or SystemExit (or even HardwareIsOnFireError – How do you know you aren't running on a custom box with specific errors defined, which some calling application would want to know about?).

  try:
      os.unlink(filename_larry)
  except:
      pass
  

  Instead using at least except Error: or in this case preferably except OSError: is considered much better practice. A quick analysis of all python modules I have installed gave me that more than 10% of all except ...: pass statements catch all exceptions, so it's still a frequent pattern in python programming.

• Deriving an exception class that does not add new behaviour (e.g. in scipy):

  class CompileError(Exception):
      pass
  

  Similarly, classes intended as abstract base class often have an explicit empty __init__ or other methods that subclasses are supposed to derive. (e.g. pebl)

  class _BaseSubmittingController(_BaseController):
      def submit(self, tasks): pass
      def retrieve(self, deferred_results): pass
  

• Testing that code runs properly for a few test values, without caring about the results (from mpmath):

  for x, error in MDNewton(mp, f, (1,-2), verbose=0,
                           norm=lambda x: norm(x, inf)):
      pass
  

• In class or function definitions, often a docstring is already in place as the obligatory statement to be executed as the only thing in the block. In such cases, the block may contain pass in addition to the docstring in order to say “This is indeed intended to do nothing.”, for example in pebl:

  class ParsingError(Exception): 
      """Error encountered while parsing an ill-formed datafile."""
      pass
  

• In some cases, pass is used as a placeholder to say “This method/class/if-block/... has not been implemented yet, but this will be the place to do it”, although I personally prefer the Ellipsis literal ... in order to strictly differentiate between this and the intentional “no-op” in the previous example. (Note that the Ellipsis literal is a valid expression only in Python 3)
  For example, if I write a model in broad strokes, I might write

  def update_agent(agent):
      ... 
  

  where others might have

  def update_agent(agent):
      pass
  

  before

  def time_step(agents):
      for agent in agents:
          update_agent(agent)
  

  as a reminder to fill in the update_agent function at a later point, but run some tests already to see if the rest of the code behaves as intended. (A third option for this case is raise NotImplementedError. This is useful in particular for two cases: Either “This abstract method should be implemented by every subclass, there is no generic way to define it in this base class”, or “This function, with this name, is not yet implemented in this release, but this is what its signature will look like”)

I give an example up on Group By between two table in Sql:

Select cn.name,ct.name,count(ct.id) totalcity from city ct left join country cn on ct.countryid = cn.id Group By cn.name,ct.name Having totalcity > 2

You can try SharpZipLib for that. Is is open source, platform independent pure c# code.

Remove method will causes a lot of shift of list elements. I think is better to make a copy:

...
new_list = []
for el in obj.my_list:
   if condition_is_true(el):
      new_list.append(el)
del obj.my_list
obj.my_list = new_list
...

Summary of the alternatives:

capture this:

auto lambda = [this](){};

use a local reference to the member:

auto& tmp = grid;
auto lambda = [ tmp](){}; // capture grid by (a single) copy
auto lambda = [&tmp](){}; // capture grid by ref

C++14:

auto lambda = [ grid = grid](){}; // capture grid by copy
auto lambda = [&grid = grid](){}; // capture grid by ref

example: https://godbolt.org/g/dEKVGD

The stdout of the process started by the docker container is available through the docker logs $containerid command (use -f to keep it going forever). Another option would be to stream the logs directly through the docker remote API.

For accessing log files (only if you must, consider logging to stdout or other standard solution like syslogd) your only real-time option is to configure a volume (like Marcus Hughes suggests) so the logs are stored outside the container and available for processing from the host or another container.

If you do not need real-time access to the logs, you can export the files (in tar format) with docker export

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

Skip all of this. Download Microsoft FUZZY LOOKUP add in. Create tables using your columns. Create a new worksheet. INPUT tables into the tool. Click all corresponding columns check boxes. Use slider for exact matches. HIT go and wait for the magic.

In which way do you want it dynamic? If you want the popup to successfully map to the background, you need to create two backgrounds. It requires both the use of element() or -moz-element() and a filter (for Firefox, use a SVG filter like filter: url(#svgBlur) since Firefox does not support -moz-filter: blur() as yet?). It only works in Firefox at the time of writing.

I still need to create a simple demo to show how it is done. You're welcome to view the source.

Since pandas 1.0.0 df.sort_values has a new parameter ignore_index which does exactly what you need:

In [1]: df2 = df.sort_values(by=['x','y'],ignore_index=True)

In [2]: df2
Out[2]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

Try with this script, maybe will be useful:

SELECT CAST('TRUE' as bit) -- RETURN 1
SELECT CAST('FALSE' as bit) --RETURN 0

Anyway I always would use a value of 1 or 0 (not TRUE or FALSE). Following your example, the update script would be:

Update Table Set BitField=CAST('TRUE' as bit) Where ID=1

mkdir()

creates only one directory at a time, if it is parent that one only. other wise it can create the sub directory(if the specified path is existed only) and do not create any directories in between any two directories. so it can not create smultiple directories in one directory

mkdirs()

create the multiple directories(in between two directories also) at a time.

I am currently using Android Studio 1.4.

For importing and adding libraries, I used the following flow ->

1. Press **Alt+Ctr+Shift+S** or Go to **File --> Project** Structure to open up the Project Structure Dialog Box.

2. Click on **Modules** to which you want to link the JAR to and Go to the Dependency Tab.

3. Click on "**+**" Button to pop up Choose Library Dependency.

4. Search/Select the dependency and rebuild the project.

I used the above approach to import support v4 and v13 libraries.

I hope this is helpful and clears up the flow.

According to the jQuery documentation, shorthand CSS properties are not supported.

Depending on what you mean by "total padding", you may be able to do something like this:

var $img = $('img');
var paddT = $img.css('padding-top') + ' ' + $img.css('padding-right') + ' ' + $img.css('padding-bottom') + ' ' + $img.css('padding-left');

If you are using PostgreSQL, this is the right way to get it. This is just an assumption where as you have a book table TITLE and PRICE column with populated data. Here's the query

SELECT xpath('/bookstore/book/title/@lang', xmlforest(book.title AS title, book.price AS price), ARRAY[ARRAY[]::TEXT[]]) FROM book LIMIT 1;

tl;dr

A generator expression is probably the most performant and simple solution to your problem:

l = [(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")]

result = next((i for i, v in enumerate(l) if v[0] == 53), None)
# 2

Explanation

There are several answers that provide a simple solution to this question with list comprehensions. While these answers are perfectly correct, they are not optimal. Depending on your use case, there may be significant benefits to making a few simple modifications.

The main problem I see with using a list comprehension for this use case is that the entire list will be processed, although you only want to find 1 element.

Python provides a simple construct which is ideal here. It is called the generator expression. Here is an example:

# Our input list, same as before
l = [(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")]

# Call next on our generator expression.
next((i for i, v in enumerate(l) if v[0] == 53), None)

We can expect this method to perform basically the same as list comprehensions in our trivial example, but what if we're working with a larger data set? That's where the advantage of using the generator method comes into play. Rather than constructing a new list, we'll use your existing list as our iterable, and use next() to get the first item from our generator.

Lets look at how these methods perform differently on some larger data sets. These are large lists, made of 10000000 + 1 elements, with our target at the beginning (best) or end (worst). We can verify that both of these lists will perform equally using the following list comprehension:

List comprehensions

"Worst case"

worst_case = ([(False, 'F')] * 10000000) + [(True, 'T')]
print [i for i, v in enumerate(worst_case) if v[0] is True]

# [10000000]
#          2 function calls in 3.885 seconds
#
#    Ordered by: standard name
#
#    ncalls  tottime  percall  cumtime  percall filename:lineno(function)
#         1    3.885    3.885    3.885    3.885 so_lc.py:1(<module>)
#         1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}

"Best case"

best_case = [(True, 'T')] + ([(False, 'F')] * 10000000)
print [i for i, v in enumerate(best_case) if v[0] is True]

# [0]
#          2 function calls in 3.864 seconds
#
#    Ordered by: standard name
#
#    ncalls  tottime  percall  cumtime  percall filename:lineno(function)
#         1    3.864    3.864    3.864    3.864 so_lc.py:1(<module>)
#         1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}

Generator expressions

Here's my hypothesis for generators: we'll see that generators will significantly perform better in the best case, but similarly in the worst case. This performance gain is mostly due to the fact that the generator is evaluated lazily, meaning it will only compute what is required to yield a value.

Worst case

# 10000000
#          5 function calls in 1.733 seconds
#
#    Ordered by: standard name
#
#    ncalls  tottime  percall  cumtime  percall filename:lineno(function)
#         2    1.455    0.727    1.455    0.727 so_lc.py:10(<genexpr>)
#         1    0.278    0.278    1.733    1.733 so_lc.py:9(<module>)
#         1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}
#         1    0.000    0.000    1.455    1.455 {next}

Best case

best_case  = [(True, 'T')] + ([(False, 'F')] * 10000000)
print next((i for i, v in enumerate(best_case) if v[0] == True), None)

# 0
#          5 function calls in 0.316 seconds
#
#    Ordered by: standard name
#
#    ncalls  tottime  percall  cumtime  percall filename:lineno(function)
#         1    0.316    0.316    0.316    0.316 so_lc.py:6(<module>)
#         2    0.000    0.000    0.000    0.000 so_lc.py:7(<genexpr>)
#         1    0.000    0.000    0.000    0.000 {method 'disable' of '_lsprof.Profiler' objects}
#         1    0.000    0.000    0.000    0.000 {next}

WHAT?! The best case blows away the list comprehensions, but I wasn't expecting the our worst case to outperform the list comprehensions to such an extent. How is that? Frankly, I could only speculate without further research.

Take all of this with a grain of salt, I have not run any robust profiling here, just some very basic testing. This should be sufficient to appreciate that a generator expression is more performant for this type of list searching.

Note that this is all basic, built-in python. We don't need to import anything or use any libraries.

I first saw this technique for searching in the Udacity cs212 course with Peter Norvig.

Usually the better way is to trigger an event (click) instead of calling the method directly.

I will put a small comparison table here (just to have it somewhere):

Servlet is mapped as /test%3F/* and the application is deployed under /app.

http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S%3F+ID?p+1=c+d&p+2=e+f#a

Method              URL-Decoded Result           
----------------------------------------------------
getContextPath()        no      /app
getLocalAddr()                  127.0.0.1
getLocalName()                  30thh.loc
getLocalPort()                  8480
getMethod()                     GET
getPathInfo()           yes     /a?+b
getProtocol()                   HTTP/1.1
getQueryString()        no      p+1=c+d&p+2=e+f
getRequestedSessionId() no      S%3F+ID
getRequestURI()         no      /app/test%3F/a%3F+b;jsessionid=S+ID
getRequestURL()         no      http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S+ID
getScheme()                     http
getServerName()                 30thh.loc
getServerPort()                 8480
getServletPath()        yes     /test?
getParameterNames()     yes     [p 2, p 1]
getParameter("p 1")     yes     c d

In the example above the server is running on the localhost:8480 and the name 30thh.loc was put into OS hosts file.

Comments

• "+" is handled as space only in the query string

• Anchor "#a" is not transferred to the server. Only the browser can work with it.

• If the url-pattern in the servlet mapping does not end with * (for example /test or *.jsp), getPathInfo() returns null.

If Spring MVC is used

• Method getPathInfo() returns null.

• Method getServletPath() returns the part between the context path and the session ID. In the example above the value would be /test?/a?+b

• Be careful with URL encoded parts of @RequestMapping and @RequestParam in Spring. It is buggy (current version 3.2.4) and is usually not working as expected.

When you put default, its called default export. You can only have one default export per file and you can import it in another file with any name you want. When you don't put default, its called named export, you have to import it in another file using the same name with curly braces inside it.

Why don't u use:

<script>
$('input').keyup(function(){
if(($('#eng').val().length > 0) && ($('#spa').val().length > 0))
    $("#submit").prop('disabled', false);
else
    $("#submit").prop('disabled', true);
});
</script>

Then delete the onkeyup function on the input.

Here is my approach for importing .sql files to MS SQL:

1. Export table from MySQL with --compatible=mssql and --extended-insert=FALSE options:

   mysqldump -u [username] -p --compatible=mssql --extended-insert=FALSE db_name table_name > table_backup.sql

2. Split the exported file with PowerShell by 300000 lines per file:

   $i=0; Get-Content exported.sql -ReadCount 300000 | %{$i++; $_ | Out-File out_$i.sql}

3. Run each file in MS SQL Server Management Studio

There are few tips how to speed up the inserts.

Other approach is to use mysqldump –where option. By using this option you can split your table on any condition which is supported by where sql clause.

I usually do like this:

from numpy import log as ln

Perhaps this can make you more comfortable.

My way to go (when there is no appropiate way to insert special chars) via CSS:

-ms-word-break: break-all;
word-break: break-all;
word-break: break-word;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;

In version r75 of three.js, you should use:

var loader = new THREE.TextureLoader();
loader.load('texture.png', function ( texture ) {
  var geometry = new THREE.SphereGeometry(1000, 20, 20);
  var material = new THREE.MeshBasicMaterial({map: texture, overdraw: 0.5});
  var mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);
});

1. type Ctrl+Alt+S (or go to Preferences)
2. go to the Plugins tab, press "Browse repositories" button
3. search:
   Visual Paradigm SDE for IntellIJ (Community edition) Modelling Case Tool
4. install it.

You need to install proper software. Now it should works well.

I guess that UML Class Diagram is only available on Ultimate Edition.

To show UML diagram click right mouse button on specific class -> Diagrams -> Show diagram... Or you can in editor click Ctrl+Alt+Shift+U. You could append new classes to diagram by drag and drop. On the top of window you could choose more options. To save UML you should just click on save icon.

line-height does fix it, but you might have to make it pretty large: on my setttings I have to increase line-height to about 1.8 before the <sup> no longer interferes with it, but this will vary from font to font.

One possible approach to get consistent line heights is to set your own superscript styling instead of the default vertical-align: super. If you use top it won't add anything to the line box, but you may have to reduce font size further to make it fit:

sup { vertical-align: top; font-size: 0.6em; }

Another hack you could try is to use positioning to move it up a bit without affecting the line box:

sup { vertical-align: top; position: relative; top: -0.5em; }

Of course this runs the risk of crashing into the line above if you don't have enough line-height.

My two cents... This is the way I understand it. (Feel free to correct me if I'm wrong)

It's time to throw out everything you know about pass by value / reference.

Because in JavaScript, it doesn't matter whether it's passed by value or by reference or whatever. What matters is mutation vs assignment of the parameters passed into a function.

OK, let me do my best to explain what I mean. Let's say you have a few objects.

var object1 = {};
var object2 = {};

What we have done is "assignment"... We've assigned 2 separate empty objects to the variables "object1" and "object2".

Now, let's say that we like object1 better... So, we "assign" a new variable.

var favoriteObject = object1;

Next, for whatever reason, we decide that we like object 2 better. So, we do a little re-assignment.

favoriteObject = object2;

Nothing happened to object1 or to object2. We haven't changed any data at all. All we did was re-assign what our favorite object is. It is important to know that object2 and favoriteObject are both assigned to the same object. We can change that object via either of those variables.

object2.name = 'Fred';
console.log(favoriteObject.name) // Logs Fred
favoriteObject.name = 'Joe';
console.log(object2.name); // Logs Joe

OK, now let's look at primitives like strings for example

var string1 = 'Hello world';
var string2 = 'Goodbye world';

Again, we pick a favorite.

var favoriteString = string1;

Both our favoriteString and string1 variables are assigned to 'Hello world'. Now, what if we want to change our favoriteString??? What will happen???

favoriteString = 'Hello everyone';
console.log(favoriteString); // Logs 'Hello everyone'
console.log(string1); // Logs 'Hello world'

Uh oh.... What has happened. We couldn't change string1 by changing favoriteString... Why?? Because we didn't change our string object. All we did was "RE ASSIGN" the favoriteString variable to a new string. This essentially disconnected it from string1. In the previous example, when we renamed our object, we didn't assign anything. (Well, not to the variable itself, ... we did, however, assign the name property to a new string.) Instead, we mutated the object which keeps the connections between the 2 variables and the underlying objects. (Even if we had wanted to modify or mutate the string object itself, we couldn't have, because strings are actually immutable in JavaScript.)

Now, on to functions and passing parameters.... When you call a function, and pass a parameter, what you are essentially doing is an "assignment" to a new variable, and it works exactly the same as if you assigned using the equal (=) sign.

Take these examples.

var myString = 'hello';

// Assign to a new variable (just like when you pass to a function)
var param1 = myString;
param1 = 'world'; // Re assignment

console.log(myString); // Logs 'hello'
console.log(param1);   // Logs 'world'

Now, the same thing, but with a function

function myFunc(param1) {
    param1 = 'world';

    console.log(param1);   // Logs 'world'
}

var myString = 'hello';
// Calls myFunc and assigns param1 to myString just like param1 = myString
myFunc(myString);

console.log(myString); // logs 'hello'

OK, now let’s give a few examples using objects instead... first, without the function.

var myObject = {
    firstName: 'Joe',
    lastName: 'Smith'
};

// Assign to a new variable (just like when you pass to a function)
var otherObj = myObject;

// Let's mutate our object
otherObj.firstName = 'Sue'; // I guess Joe decided to be a girl

console.log(myObject.firstName); // Logs 'Sue'
console.log(otherObj.firstName); // Logs 'Sue'

// Now, let's reassign the variable
otherObj = {
    firstName: 'Jack',
    lastName: 'Frost'
};

// Now, otherObj and myObject are assigned to 2 very different objects
// And mutating one object has no influence on the other
console.log(myObject.firstName); // Logs 'Sue'
console.log(otherObj.firstName); // Logs 'Jack';

Now, the same thing, but with a function call

function myFunc(otherObj) {

    // Let's mutate our object
    otherObj.firstName = 'Sue';
    console.log(otherObj.firstName); // Logs 'Sue'

    // Now let's re-assign
    otherObj = {
        firstName: 'Jack',
        lastName: 'Frost'
    };
    console.log(otherObj.firstName); // Logs 'Jack'

    // Again, otherObj and myObject are assigned to 2 very different objects
    // And mutating one object doesn't magically mutate the other
}

var myObject = {
    firstName: 'Joe',
    lastName: 'Smith'
};

// Calls myFunc and assigns otherObj to myObject just like otherObj = myObject
myFunc(myObject);

console.log(myObject.firstName); // Logs 'Sue', just like before

OK, if you read through this entire post, perhaps you now have a better understanding of how function calls work in JavaScript. It doesn't matter whether something is passed by reference or by value... What matters is assignment vs mutation.

Every time you pass a variable to a function, you are "Assigning" to whatever the name of the parameter variable is, just like if you used the equal (=) sign.

Always remember that the equals sign (=) means assignment. Always remember that passing a parameter to a function in JavaScript also means assignment. They are the same and the 2 variables are connected in exactly the same way (which is to say they aren't, unless you count that they are assigned to the same object).

The only time that "modifying a variable" affects a different variable is when the underlying object is mutated (in which case you haven't modified the variable, but the object itself.

There is no point in making a distinction between objects and primitives, because it works the same exact way as if you didn't have a function and just used the equal sign to assign to a new variable.

The only gotcha is when the name of the variable you pass into the function is the same as the name of the function parameter. When this happens, you have to treat the parameter inside the function as if it was a whole new variable private to the function (because it is)

function myFunc(myString) {
    // myString is private and does not affect the outer variable
    myString = 'hello';
}

var myString = 'test';
myString = myString; // Does nothing, myString is still 'test';

myFunc(myString);
console.log(myString); // Logs 'test'

You can do like this in more natural way,

case expression
when condtion1
   function
when condition2
   function
else
   function
end

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

you should change that to define the plugin only once and do twice execution areas...like the following...and the generateDirectory should be set (based on the docs)..

<plugin>
  <groupId>org.jvnet.jaxb2.maven2</groupId>
  <artifactId>maven-jaxb2-plugin</artifactId>
  <version>0.7.1</version>
  <executions>
    <execution>

It seemed to me that you are fighting against single artifact rule of maven...may be you should think about this.

It's important to add that the main difference of running mvn with -U and without -U is that -U will override your local SNAPSHOT jars with remote SNAPSHOT jars.

Local SNAPSHOT jars created from local mvn install in cases where you have other modules of your proj that generate jars.

Example:

URL imageURL = this.getClass().getClassLoader().getResource("Gui/icon/report-go-icon.png");
ImageIcon iChing = new ImageIcon("C:\\Users\\RrezartP\\Documents\\NetBeansProjects\\Inventari\\src\\Gui\\icon\\report-go-icon.png");      
btnReport.setIcon(iChing); 
System.out.println(imageURL);

Looks like you are confusing Html.ActionLink() for Url.Action(). Url.Action has no parameters to set the Target, because it only returns a URL.

Based on your current code, the anchor should probably look like:

<a href="@Url.Action("RunReport", "Performance", new { reportView = Model.ReportView.ToString() })" 
   type="submit" 
   id="runReport" 
   target="_blank"
   class="button Secondary">
     @Reports.RunReport
</a>

you need /q at the end

MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q

exit() should do it.

d={1:'a',2:'b'}
sum=0
for i in range(0,len(d),1):
   sum=sum+1
i=i+1
print i

OUTPUT=2

As @Arnab and @Mike pointed out, an array is not a list. Few differences are 1) arrays are fixed size during initialization 2) arrays normally support lesser operations than a list.

Maybe an overkill in most cases, but here is a basic 2d array implementation that leverages hardware array implementation using python ctypes(c libraries)

import ctypes
class Array:
    def __init__(self,size,foo): #foo is the initial value
        self._size = size
        ArrayType = ctypes.py_object * size
        self._array = ArrayType()
        for i in range(size):
            self._array[i] = foo
    def __getitem__(self,index):
        return self._array[index]
    def __setitem__(self,index,value):
        self._array[index] = value
    def __len__(self):
        return self._size

class TwoDArray:
    def __init__(self,columns,rows,foo):
        self._2dArray = Array(rows,foo)
        for i in range(rows):
            self._2dArray[i] = Array(columns,foo)

    def numRows(self):
        return len(self._2dArray)
    def numCols(self):
        return len((self._2dArray)[0])
    def __getitem__(self,indexTuple):
        row = indexTuple[0]
        col = indexTuple[1]
        assert row >= 0 and row < self.numRows() \
               and col >=0 and col < self.numCols(),\
               "Array script out of range"
        return ((self._2dArray)[row])[col]

if(__name__ == "__main__"):
    twodArray = TwoDArray(4,5,5)#sample input
    print(twodArray[2,3])

If you are on MAMP

Check your port number as well generally it is

Host localhost

Port 8889

User root

Password root

Socket /Applications/MAMP/tmp/mysql/mysql.sock

I know this is an old question and I probably won't help, but many Linux distributions(e.g., ubuntu) have a "Live cd/usb" function, so if you really need to run this script, you could try booting your computer into Linux. Just burn a .iso to a flash drive (here's how http://goo.gl/U1wLYA), start your computer with the drive plugged in, and press the F key for boot menu. If you choose "...USB...", you will boot into the OS you just put on the drive.

How to specify the JDK version?

Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source & target or (3) with release.

Spring Boot

1. <java.version> is not referenced in the Maven documentation.
   It is a Spring Boot specificity.
   It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :

   1.8

Feel free to use it if you use Spring Boot.

maven-compiler-plugin with source & target

2. Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties are equivalent.

That is indeed :

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

is equivalent to :

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

source

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

maven-compiler-plugin with release instead of source & target

3. The maven-compiler-plugin 3.6 and later versions provide a new way :

   org.apache.maven.plugins maven-compiler-plugin 3.8.0 9

You could also declare just :

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time it will not work as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release : a new JVM standard option that we could pass from Java 9 :

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

The first way (<java.version>) is allowed only if you use Spring Boot.

For Java 8 and below :

About the two other ways : valuing the maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

From Java 9 :

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?

It is not a problem if the JDK referenced by the JAVA_HOME is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap JVM option with as value the path of the rt.jar of the target version.

An important thing to consider is that the source and the target version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.

To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.

How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?

For example, if your JAVA_HOME refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <compilerVersion>1.8</compilerVersion>      
        <fork>true</fork>
        <executable>D:\jdk1.8\bin\javac</executable>                
    </configuration>
</plugin>

You could have more details in examples with maven compiler plugin.

It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.

Why the compiler plugin is traced in the output at the execution of the Maven package goal even if you don't specify it in the pom.xml?

To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId : org.apache.maven.plugins) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.

In the output of the mvn help:effective-pom command, you could see the declaration of these core plugins in the <build><plugins> element, for example :

...
<plugin>
   <artifactId>maven-clean-plugin</artifactId>
   <version>2.5</version>
   <executions>
     <execution>
       <id>default-clean</id>
       <phase>clean</phase>
       <goals>
         <goal>clean</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.6</version>
   <executions>
     <execution>
       <id>default-testResources</id>
       <phase>process-test-resources</phase>
       <goals>
         <goal>testResources</goal>
       </goals>
     </execution>
     <execution>
       <id>default-resources</id>
       <phase>process-resources</phase>
       <goals>
         <goal>resources</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <executions>
     <execution>
       <id>default-compile</id>
       <phase>compile</phase>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
     <execution>
       <id>default-testCompile</id>
       <phase>test-compile</phase>
       <goals>
         <goal>testCompile</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
  ...

You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.

Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.

Lets say I'm trying to render the below HTML.

let myHTML = "<p>Go to this <a href='https://google.com'>website </b></p>";

JSON.parse(JSON.stringify(myHTML)) This would give you a HTML element which you can set using innerHTML.

Like this document.getElementById("demo").innerHTML = JSON.parse(JSON.stringify(myHTML));

People are storing their HTML as an object here. However the method I suggested does the same without having to use an Object.

Call this before the query:

set define off;

Alternatively, hacky:

update t set country = 'Trinidad and Tobago' where country = 'trinidad &' || ' tobago';

From Tuning SQL*Plus:

SET DEFINE OFF disables the parsing of commands to replace substitution variables with their values.

std::queue<myclass*> that's it

Here is an example:

html_code +="<td>" +
            "<select name='[row"+count+"]' data-placeholder='Choose One...' class='chosen-select form-control' tabindex='2'>"+
                "<option selected='selected' disabled='disabled' value=''>Select Exam Name</option>"+
                "<?php foreach($NM_EXAM as $ky=>$row) {
                echo '<option value='."$row->EXAM_ID". '>' . $row->EXAM_NAME . '</option>';
               } ?>"+
            "</select>"+
        "</td>";

Or

echo '<option value=\"'.$row->EXAM_ID. '\">' . $row->EXAM_NAME . '</option>';

Try this

var div = document.getElementById("test");
var spans = div.getElementsByTagName("span");

for(i=0;i<spans.length;i++)
{
  alert(spans[i].innerHTML);
}

You could simplify the above equations using the following:

boolean flag = sqlInt != 0;

If the int representation (sqlInt) of the boolean is 0 (false), the boolean (flag) will be false, otherwise it will be true.

Concise code is always nicer to work with :)

Use this method:

$_product = wc_get_product( $id );

Official API-docs: wc_get_product

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

the problem is that href is href="#" you must remove href="#" in all tag

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

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

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

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

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

In this example above IntObjectHashMap.

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

https://github.com/blueimp/JavaScript-Load-Image is a modern javascript library that can not only extract the exif orientation flag - it can also correctly mirror/rotate JPEG images on the client side.

I just solved the same problem with this library: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images

Great answers, but if you look for a singe line do all, you can concatenate, alias and enjoy the convenience:

git add * && git commit -am "<commit message>"

It is a single line but two commands, and as mentioned you can alias these commands:

alias git-aac="git add * && git commit -am " (the space at the end is important) because you are going to parameterize the new short hand command.

From this moment on, you will be using this alias:

git-acc "<commit message>"

You basically say:

git, add for me all untracked files and commit them with this given commit message.

Hope you use Linux, hope this helps.

Note you can add the Microsoft.AspNetCore.WebUtilities nuget package from Microsoft and then use this to append values to query string:

QueryHelpers.AddQueryString(longurl, "action", "login1")
QueryHelpers.AddQueryString(longurl, new Dictionary<string, string> { { "action", "login1" }, { "attempts", "11" } });

Declare @phoneNumber int

select @phoneNumber=Isnull('08041159620',0);

Give error :

The conversion of the varchar value '8041159620' overflowed an int column.: select cast('8041159620' as int)

AS

Integer is defined as :

Integer (whole number) data from -2^31 (-2,147,483,648) through 2^31 - 1 (2,147,483,647). Storage size is 4 bytes. The SQL-92 synonym for int is integer.

Solution

Declare @phoneNumber bigint

Reference

another important point is that Random.nextInt(n) is repeatable since you can create two Random object with the same seed. This is not possible with Math.random().

Not sure if your issue was fixed and how. But I faced the same issue while trying to make a tomcat instance running.

• The port was not in use.
• There was no firewall issue.
• Tomcat instance was starting up fine.

I changed the custom shutdown script and this issue was fixed. Old Script:-

export CATALINA_HOME=/home/lrsprod/ELA/tomcat6/apache-tomcat-6.0.35 $CATALINA_HOME/bin/catalina.sh stop

Added catalina base to it.

export CATALINA_BASE=/home/lrsprod/ELA/tomcat6/ela_instance export CATALINA_HOME=/home/lrsprod/ELA/tomcat6/apache-tomcat-6.0.35 $CATALINA_HOME/bin/catalina.sh stop

That did the trick.

Try this

function setAttribs(elm, ob) {
    //var r = [];
    //var i = 0;
    for (var z in ob) {
        if (ob.hasOwnProperty(z)) {
            try {
                elm[z] = ob[z];
            }
            catch (er) {
                elm.setAttribute(z, ob[z]);
            }
        }
    }
    return elm;
}

Edit

gulp-util is deprecated and should be avoid, so it's recommended to use minimist instead, which gulp-util already used.

So I've changed some lines in my gulpfile to remove gulp-util:

var argv = require('minimist')(process.argv.slice(2));

gulp.task('styles', function() {
  return gulp.src(['src/styles/' + (argv.theme || 'main') + '.scss'])
    …
});

Original

In my project I use the following flag:

gulp styles --theme literature

Gulp offers an object gulp.env for that. It's deprecated in newer versions, so you must use gulp-util for that. The tasks looks like this:

var util = require('gulp-util');

gulp.task('styles', function() {
  return gulp.src(['src/styles/' + (util.env.theme ? util.env.theme : 'main') + '.scss'])
    .pipe(compass({
        config_file: './config.rb',
        sass   : 'src/styles',
        css    : 'dist/styles',
        style  : 'expanded'

    }))
    .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'ff 17', 'opera 12.1', 'ios 6', 'android 4'))
    .pipe(livereload(server))
    .pipe(gulp.dest('dist/styles'))
    .pipe(notify({ message: 'Styles task complete' }));
});

The environment setting is available during all subtasks. So I can use this flag on the watch task too:

gulp watch --theme literature

And my styles task also works.

Unofficial 64-bit installers for NumPy and SciPy are available at http://www.lfd.uci.edu/~gohlke/pythonlibs/

Make sure that you download & install the packages (aka. wheels) that match your CPython version and bitness (ie. cp35 = Python v3.5; win_amd64 = x86_64).

You'll want to install NumPy first; From a CMD prompt with administrator privileges for a system-wide (aka. Program Files) install:

C:\>pip install numpy-<version>+mkl-cp<ver-spec>-cp<ver-spec>m-<cpu-build>.whl

Or include the --user flag to install to the current user's application folder (Typically %APPDATA%\Python on Windows) from a non-admin CMD prompt:

C:\>pip install --user numpy-<version>+mkl-cp<ver-spec>-cp<ver-spec>m-<cpu-build>.whl

Then do the same for SciPy:

C:\>pip install [--user] scipy-<version>-cp<ver-spec>-cp<ver-spec>m-<cpu-build>.whl

Don't forget to replace <version>, <ver-spec>, and <cpu-build> appropriately if you copy & paste any of these examples. And also that you must use the numpy & scipy packages from the ifd.uci.edu link above (or else you will get errors if you try to mix & match incompatible packages -- uninstall any conflicting packages first [ie. pip list]).

Just change moveCamera to animateCamera like below

Googlemap.animateCamera(CameraUpdateFactory.newLatLngZoom(locate, 16F))

It's a pity that both of the answers analyze the problem but didn't give a direct answer. Let's see the code.

Z = np.array([1.0, 1.0, 1.0, 1.0])  

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B
Nlayers = Z.size
N = 3
TempLake = np.zeros((N+1, Nlayers))
kOUT = np.zeros(N + 1)

for i in xrange(N):
    # store the i-th result of
    # function "func" in i-th item in kOUT
    kOUT[i] = func(TempLake[i], Z)

The error shows that you set the ith item of kOUT(dtype:int) into an array. Here every item in kOUT is an int, can't directly assign to another datatype. Hence you should declare the data type of kOUT when you create it. For example, like:

Change the statement below:

kOUT = np.zeros(N + 1)

into:

kOUT = np.zeros(N + 1, dtype=object)

or:

kOUT = np.zeros((N + 1, N + 1))

All code:

import numpy as np
Z = np.array([1.0, 1.0, 1.0, 1.0])

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B

Nlayers = Z.size
N = 3
TempLake = np.zeros((N + 1, Nlayers))

kOUT = np.zeros(N + 1, dtype=object)
for i in xrange(N):
    kOUT[i] = func(TempLake[i], Z)

Hope it can help you.

First you have load session library.

$this->load->library("session");

You can load it in auto load, which I think is better.

To set session

$this->session->set_userdata("SESSION_NAME","VALUE");

To extract Data

$this->session->userdata("SESSION_NAME");

I've tried all of these solutions excluding the COBOL answer... lol

None of these solutions were good enough. I needed randoms in a fast for int loop and I was getting tons of duplicate values even in very wide ranges. After settling for kind of random results far too long I decided to finally tackle this problem once and for all.

It's all about the seed.

I create a random integer by parsing out the non-digits from Guid, then I use that to instantiate my Random class.

public int GenerateRandom(int min, int max)
{
    var seed = Convert.ToInt32(Regex.Match(Guid.NewGuid().ToString(), @"\d+").Value);
    return new Random(seed).Next(min, max);
}

Update: Seeding isn't necessary if you instantiate the Random class once. So it'd be best to create a static class and call a method off that.

public static class IntUtil
{
   private static Random random;

   private static void Init()
   {
      if (random == null) random = new Random();
   }

   public static int Random(int min, int max)
   {
      Init();
      return random.Next(min, max);
   }
}

Then you can use the static class like so..

for(var i = 0; i < 1000; i++)
{
   int randomNumber = IntUtil.Random(1,100);
   Console.WriteLine(randomNumber); 
}

I admit I like this approach better.

To check your MySQL version on your mac, navigate to the directory where you installed it (default is usr/local/mysql/bin) and issue this command:

./mysql --version

Alternatively, to avoid needing to navigate to that specific dir to run the command, add its location to your path ($PATH). There's more than one way to add a dir to your $PATH (with explanations on stackoverflow and other places on how to do so), such as adding it to your ./bash_profile.

After adding the mysql bin dir to your $PATH, verify it's there by executing:

echo $PATH

Thereafter you can check your mysql version from anywhere by running (note no "./"):

mysql --version

It looks like derivedFactor from the mosaic package was designed for this. In this example, it would look something like:

library(mosaic)
myfile <- mutate(myfile, V5 = derivedFactor(
    "1" = (V1==1 & V2!=4),
    "2" = (V2==4 & V3!=1),
    .method = "first",
    .default = 0
    ))

(If you want the outcome to be numeric instead of a factor, wrap the derivedFactor with an as.numeric.)

Note that the .default option combined with .method = "first" sets the "else" condition -- this approach is described in the help file for derivedFactor.

Actually, to properly support sorting, filtering, etc. a CollectionViewSource should be used as a link between the DataGrid and the list, like this:

<Window.Resources>
  <CollectionViewSource x:Key="ItemCollectionViewSource" CollectionViewType="ListCollectionView"/>
</Window.Resources>   

The DataGrid line looks like this:

<DataGrid
  DataContext="{StaticResource ItemCollectionViewSource}"
  ItemsSource="{Binding}"
  AutoGenerateColumns="False">  

In the code behind, you link CollectionViewSource with your link.

CollectionViewSource itemCollectionViewSource;
itemCollectionViewSource = (CollectionViewSource)(FindResource("ItemCollectionViewSource"));
itemCollectionViewSource.Source = itemList;

For detailed example see my article on CoedProject: http://www.codeproject.com/Articles/683429/Guide-to-WPF-DataGrid-formatting-using-bindings

If you want to convert all elements of a to a single numeric vector and length(a) is greater than 1 (OK, even if it is of length 1), you could unlist the object first and then convert.

as.numeric(unlist(a))
# [1]  10  38  66 101 129 185 283 374

Bear in mind that there aren't any quality controls here. Also, X$Days a mighty odd name.

Use jps to list running java processes. The command returns the process id along with the main class. You can use kill command to kill the process with the returned id or use following one liner script.

kill $(jps | grep <MainClass> | awk '{print $1}')

MainClass is a class in your running java program which contains the main method.

If you are using babel, you bind 'this' using ES7 bind operator https://babeljs.io/docs/en/babel-plugin-transform-function-bind#auto-self-binding

export default class SignupPage extends React.Component {
  constructor(props) {
    super(props);

  handleSubmit(e) {
    e.preventDefault(); 

    const data = {

    } 
  }

  render() {

    const {errors} = this.props;

    return (
      <div className="view-container registrations new">
        <main>
          <form id="sign_up_form" onSubmit={::this.handleSubmit}>

  }

}

For anyone checking this using python 3:

If you want to print the following output "100% correct":

python 3.8: print("100% correct")
python 3.7 and less: print("100%% correct")

A neat programming workaround for compatibility across diff versions of python is shown below:

Note: If you have to use this, you're probably experiencing many other errors... I'd encourage you to upgrade / downgrade python in relevant machines so that they are all compatible.

DevOps is a notable exception to the above -- implementing the following code would indeed be appropriate for specific DevOps / Debugging scenarios.

import sys

if version_info.major==3:
    if version_info.minor>=8:
        my_string = "100% correct"
    else:
        my_string = "100%% correct"

# Finally
print(my_string)

Based on @carlosfigueira 's answer, I looked further into WebClient's methods and found UploadValues, which is exactly what I want:

Using client As New Net.WebClient
    Dim reqparm As New Specialized.NameValueCollection
    reqparm.Add("param1", "somevalue")
    reqparm.Add("param2", "othervalue")
    Dim responsebytes = client.UploadValues(someurl, "POST", reqparm)
    Dim responsebody = (New Text.UTF8Encoding).GetString(responsebytes)
End Using

The key part is this:

client.UploadValues(someurl, "POST", reqparm)

It sends whatever verb I type in, and it also helps me create a properly url encoded form data, I just have to supply the parameters as a namevaluecollection.
