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

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

If you are using grunt to build your application, it's possible that during build the paths change. In this case you need to modify your grunt file like this:

copy: {
        main: {
            files: [{
                src: ['fonts/**'],
                dest: 'dist/fonts/',
                filter: 'isFile',
                expand: true,
                flatten: true
            }, {
                src: ['bower_components/font-awesome/fonts/**'],
                dest: 'dist/css/',
                filter: 'isFile',
                expand: true,
                flatten: false
            }]
        }
    },

from datetime import datetime, timedelta

yesterday = datetime.now() - timedelta(days=1)
yesterday.strftime('%m%d%y')

Start Day Time : SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), '00:00:00')

End Day Time : SELECT DATEADD(day, DATEDIFF(day, 0, GETDATE()), '23:59:59')

The best solution is not to use the same element for column and panel:

<div class="row">
    <div class="col-md-3">
        <div class="panel" id="gameplay-away-team">Away Team</div>
    </div>
    <div class="col-md-6">
        <div class="panel" id="gameplay-baseball-field">Baseball Field</div>
    </div>
    <div class="col-md-3">
        <div class="panel" id="gameplay-home-team">Home Team</div>
    </div>
</div>

and some more styles:

#gameplay-baseball-field {
  padding-right: 10px;
  padding-left: 10px;
}

Updated answer for ES6+ is here.

arr = [1, 2, 3]; 

arr.forEach(function(i, idx, array){
   if (idx === array.length - 1){ 
       console.log("Last callback call at index " + idx + " with value " + i ); 
   }
});

would output:

Last callback call at index 2 with value 3

The way this works is testing arr.length against the current index of the array, passed to the callback function.

Firebug shows this correctly because your Browser automagically fixes the bad markup for you. This behaviour is not specified anywhere and can (will) vary from browser to browser. Those tags are required by the DOCTYPE you're using and should not be omitted.

The html element is the root element of every html page. If you look at all other elements' description it says where an element can be used (and almost all elements require either head or body).

For those mentioning using Object.keys(localStorage)... don't because it won't work in Firefox (ironically because Firefox is faithful to the spec). Consider this:

localStorage.setItem("key", "value1")
localStorage.setItem("key2", "value2")
localStorage.setItem("getItem", "value3")
localStorage.setItem("setItem", "value4")

Because key, getItem and setItem are prototypal methods Object.keys(localStorage) will only return ["key2"].

You are best to do something like this:

let t = [];
for (let i = 0; i < localStorage.length; i++) {
  t.push(localStorage.key(i));
}

For me it was that I could not cluster my zookeeper.

This isn't an answer. I just want to show that IF NOT EXISTS(...) INSERT method isn't safe. You have to execute first Session #1 and then Session #2. After v #2 you will see that without an UNIQUE index you could get duplicate pairs (SoftwareName,SoftwareSystemType). Delay from session #1 is used to give you enough time to execute the second script (session #2). You could reduce this delay.

Session #1 (SSMS > New Query > F5 (Execute))

I've found that the command was wrong, correct command contains "broadcast" instead of "start":

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test from adb" -n com.whereismywifeserver/.IntentReceiver

I came up with this solution which works in my case where I have objects created on multiple threads and are serializable:

public abstract class ObjBase implements Serializable
    private static final long serialVersionUID = 1L;
    private static final AtomicLong atomicRefId = new AtomicLong();

    // transient field is not serialized
    private transient long refId;

    // default constructor will be called on base class even during deserialization
    public ObjBase() {
       refId = atomicRefId.incrementAndGet()
    }

    public long getRefId() {
        return refId;
    }
}

Additional information about removing/uninstalling composer

Answers above did not help me, but what did help me is removing:

1. ~/.cache/composer
2. ~/.local/share/composer
3. ~/.config/composer

Hope this helps.

@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the + operator fails for strings in EL (which is correct), then just do:

<c:out value="abc${test}" />

Or if abc is to obtained from another scoped variable named ${resp}, then do:

<c:out value="${resp}${test}" />

On the command prompt, do:

netstat -nb

If you want Selected.Value being worked you have to do following things:

1. Set DisplayMember
2. Set ValueMember
3. Set DataSource (not use Items.Add, Items.AddRange, DataBinding etc.)

The key point is Set DataSource!

The command JG simply means: Jump if Greater. The result of the preceding instructions is stored in certain processor flags (in this it would test if ZF=0 and SF=OF) and jump instruction act according to their state.

In Anjuta, go to the Build menu, then Configure Project. In the Configure Options box, add:

LDFLAGS='-lpthread'

Came here looking for an answer to the same problem, but I'm using WCF for NET Core. If you're in the same boat, use:

client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication = 
    new X509ServiceCertificateAuthentication()
    {
        CertificateValidationMode = X509CertificateValidationMode.None,
        RevocationMode = X509RevocationMode.NoCheck
    };

If your only goal by removing the listeners is to stop them from running, you can add an event listener to the window capturing and canceling all events of the given type:

window.addEventListener(type, function (event) {
    event.stopPropagation();
}, true);

Passing in true for the third parameter causes the event to be captured on the way down. Stopping propagation means that the event never reaches the listeners that are listening for it.

Keep in mind though that this has very limited use as you can't add new listeners for the given type (they will all be blocked). There are ways to get around this somewhat, e.g., by firing a new kind of event that only your listeners would know to listen for. Here is how you can do that:

window.addEventListener('click', function (event) {
    // (note: not cross-browser)
    var event2 = new CustomEvent('click2', {detail: {original: event}});
    event.target.dispatchEvent(event2);
    event.stopPropagation();
}, true);

element.addEventListener('click2', function(event) {
    event = event.detail && event.detail.original ?
        event.detail.original :
        event;
    // ... do something with event ...
});

However, note that this may not work as well for fast events like mousemove, given that the re-dispatching of the event introduces a delay.

Better would be to just keep track of the listeners added in the first place, as outlined in Martin Wantke's answer, if you need to do this.

If you'll check smaller than 10, you haven't to create a new function for that. Just assign a variable into brackets and return it with ternary operator.

(m = new Date().getMonth() + 1) < 10 ? `0${m}` : `${m}`

If all you're trying to do is select the first blank cell in a given column, you can give this a try:

Code:

Public Sub SelectFirstBlankCell()
    Dim sourceCol As Integer, rowCount As Integer, currentRow As Integer
    Dim currentRowValue As String

    sourceCol = 6   'column F has a value of 6
    rowCount = Cells(Rows.Count, sourceCol).End(xlUp).Row

    'for every row, find the first blank cell and select it
    For currentRow = 1 To rowCount
        currentRowValue = Cells(currentRow, sourceCol).Value
        If IsEmpty(currentRowValue) Or currentRowValue = "" Then
            Cells(currentRow, sourceCol).Select
        End If
    Next
End Sub

Before Selection - first blank cell to select:

After Selection:

Regarding the first (and great) answer from chris who proposed a solution to the situation where the class members are held as a "true composite" members (i.e.- not as pointers nor references):

The note is a bit large, so I will demonstrate it here with some sample code.

When you chose to hold the members as I mentioned, you have to keep in mind also these two things:

1. For every "composed object" that does not have a default constructor - you must initialize it in the initialization list of all the constructor's of the "father" class (i.e.- BigMommaClass or MyClass in the original examples and MyClass in the code below), in case there are several (see InnerClass1 in the example below). Meaning, you can "comment out" the m_innerClass1(a) and m_innerClass1(15) only if you enable the InnerClass1 default constructor.

2. For every "composed object" that does have a default constructor - you may initialize it within the initialization list, but it will work also if you chose not to (see InnerClass2 in the example below).

See sample code (compiled under Ubuntu 18.04 (Bionic Beaver) with g++ version 7.3.0):

#include <iostream>

using namespace std;

class InnerClass1
{
    public:
        InnerClass1(int a) : m_a(a)
        {
            cout << "InnerClass1::InnerClass1 - set m_a:" << m_a << endl;
        }

        /* No default constructor
        InnerClass1() : m_a(15)
        {
            cout << "InnerClass1::InnerClass1() - set m_a:" << m_a << endl;
        }
        */

        ~InnerClass1()
        {
            cout << "InnerClass1::~InnerClass1" << endl;
        }

    private:
        int m_a;
};

class InnerClass2
{
    public:
        InnerClass2(int a) : m_a(a)
        {
            cout << "InnerClass2::InnerClass2 - set m_a:" << m_a << endl;
        }

        InnerClass2() : m_a(15)
        {
            cout << "InnerClass2::InnerClass2() - set m_a:" << m_a << endl;
        }

        ~InnerClass2()
        {
            cout << "InnerClass2::~InnerClass2" << endl;
        }

    private:
        int m_a;
};

class MyClass
{
    public:
        MyClass(int a, int b) : m_innerClass1(a), /* m_innerClass2(a),*/ m_b(b)
        {
            cout << "MyClass::MyClass(int b) - set m_b to:" << m_b << endl;
        }

         MyClass() : m_innerClass1(15), /*m_innerClass2(15),*/ m_b(17)
        {
            cout << "MyClass::MyClass() - m_b:" << m_b << endl;
        }

        ~MyClass()
        {
            cout << "MyClass::~MyClass" << endl;
        }

    private:
        InnerClass1 m_innerClass1;
        InnerClass2 m_innerClass2;
        int m_b;
};

int main(int argc, char** argv)
{
    cout << "main - start" << endl;

    MyClass obj;

    cout << "main - end" << endl;
    return 0;
}

DateTimeFormatter in Java 8 is immutable and thread-safe alternative to SimpleDateFormat.

You can simply use setInterval utility and use arrow function as callback so that this will point to the component instance.

For ex:

this.interval = setInterval( () => { 
    // call your functions like 
    this.getList();
    this.updateInfo();
});

Inside your ngOnDestroy lifecycle hook, clear the interval.

ngOnDestroy(){
    clearInterval(this.interval);
}

If you are using Entity Framework like me, you should define Time out on Startup class as follows:

 services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"), o => o.CommandTimeout(180)));

According to Laravel Documentation states you can use this way:

$result->isEmpty();

The isEmpty method returns true if the collection is empty; otherwise, false is returned.

If you are using md-select and ng-repeat ing md-option from angular material then you can add ng-model-options="{trackBy: '$value.id'}" to the md-select tag ash shown in this pen

Code:

<md-select ng-model="user" style="min-width: 200px;" ng-model-options="{trackBy: '$value.id'}">_x000D_
  <md-select-label>{{ user ? user.name : 'Assign to user' }}</md-select-label>_x000D_
  <md-option ng-value="user" ng-repeat="user in users">{{user.name}}</md-option>_x000D_
</md-select>

define "display it dynamically" ? that implies the table is being built via javascript and some sort of Ajax-y update .. if you just want to build the table using PHP that's really not what I would call 'dynamic'

If you mean to do aggregation you can use the aggregation features of the ORM:

from django.db.models import Count
Members.objects.values('designation').annotate(dcount=Count('designation'))

This results in a query similar to

SELECT designation, COUNT(designation) AS dcount
FROM members GROUP BY designation

and the output would be of the form

[{'designation': 'Salesman', 'dcount': 2}, 
 {'designation': 'Manager', 'dcount': 2}]

I went into wp-config/ and deleted the object-cache.php and advanced-cache.php and it worked fine for me.

c(df$x, df$y)
# returns: 26 21 20 34 29 28

if the particular order is important then:

M = as.matrix(df)
c(m[1,], c[2,], c[3,])
# returns 26 34 21 29 20 28 

Or more generally:

m = as.matrix(df)
q = c()
for (i in seq(1:nrow(m))){
  q = c(q, m[i,])
}

# returns 26 34 21 29 20 28

If you find the above to be ugly. You should consider using a DSL for constraints. Such as SnapKit Makes constraint API much more user-friendly

view.snp.makeConstraints { make in
    make.edges.equalToSuperview()
}

I use the following command in order to remove conflict using command line

svn revert "location of conflict folder" -R
svn cleanup
svn update

for reverting current directory

svn revert . -R

NEQ is usually used for numbers and == is typically used for string comparison.

I cannot find any documentation that mentions a specific and equivalent inequality operand for string comparison (in place of NEQ). The solution using IF NOT == seems the most sound approach. I can't immediately think of a circumstance in which the evaluation of operations in a batch file would cause an issue or unexpected behavior when applying the IF NOT == comparison method to strings.

I wish I could offer insight into how the two functions behave differently on a lower level - would disassembling separate batch files (that use NEQ and IF NOT ==) offer any clues in terms of which (unofficially documented) native API calls conhost.exe is utilizing?

Try to put

doc.fromHTML($('#target').get(0), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

instead of

doc.fromHTML($('#target').html(), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.

In the case the first arg is '-v', then do your conditional ps -ef, else in all other cases throw the usage.

#!/bin/sh
case $1 in
  '-v') if [ "$1" = -v ]; then
         echo "`ps -ef | grep -v '\['`"
        else
         echo "`ps -ef | grep '\[' | grep root`"
        fi;;
     *) echo "usage: $0 [-v]"
        exit 1;; #It is good practice to throw a code, hence allowing $? check
esac

If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.

#!/bin/sh

usage ()
 {
  echo "usage: $0 [-v]"
  exit 1
 }

unset arg_match

for arg in $*
 do
  case $arg in
    '-v') if [ "$arg" = -v ]; then
           echo "`ps -ef | grep -v '\['`"
          else
           echo "`ps -ef | grep '\[' | grep root`"
          fi
          arg_match=1;; # this is set, but could increment.
       *) ;;
  esac
done

if [ ! $arg_match ]
 then
  usage
fi

But, allow multiple occurrences of an argument is convenient to use in situations such as:

$ adduser -u:sam -s -f -u:bob -trace -verbose

We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:

$ adduser -u sam -s -f -u bob -trace -verbose

An int (or any other data type for that matter) is already stored as bytes in memory. So why not just copy the memory directly?

memcpy(arrayOfByte, &x, sizeof x);

A simple elegant one liner that will also work with any other data type.

If you need the bytes reversed you can use std::reverse

memcpy(arrayOfByte, &x, sizeof x);
std::reverse(arrayOfByte, arrayOfByte + sizeof x);

or better yet, just copy the bytes in reverse to begin with

BYTE* p = (BYTE*) &x;
std::reverse_copy(p, p + sizeof x, arrayOfByte);

If you don't want to make a copy of the data at all, and just have its byte representation

BYTE* bytes = (BYTE*) &x;

As an alternative to the chosen answer, and with the same safe semantics of Marcel's, here is a compact way of using a Python dictionary to specify the values. It has the benefit of being easy to modify as you add or remove columns to insert:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  insert='insert into Songs ({0}) values ({1})'.
        .format(','.join(meta_cols), ','.join( ['%s']*len(meta_cols) ))
  args = [ meta[i] for i in meta_cols ]
  cursor=db.cursor()
  cursor.execute(insert,args)
  db.commit()

Where meta is the dictionary holding the values to insert. Update can be done in the same way:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  update='update Songs set {0} where id=%s'.
        .format(','.join([ '{0}=%s'.format(c) for c in meta_cols ]))
  args = [ meta[i] for i in meta_cols ]
  args.append( songid )
  cursor=db.cursor()
  cursor.execute(update,args)
  db.commit()

$today_day = date('D'); //Or add your own date
$start_of_week = date('Ymd');
$end_of_week = date('Ymd');

if($today_day != "Mon")
    $start_of_week = date('Ymd', strtotime("last monday"));

if($today_day != "Sun")
                    $end_of_week = date('Ymd', strtotime("next sunday"));

This new issue is caused by the latest version of Android.

Go to your project root folder, open gradle.properties, and add the following options:

org.gradle.daemon=true

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

org.gradle.parallel=true

org.gradle.configureondemand=true

Then add these changes in your build.gradle file:

dexOptions {
        incremental = true
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
}

How to change your global broadcast to LocalBroadcast

1) Create Instance

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2) For registering BroadcastReceiver

Replace

registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

With

localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3) For sending broadcast message

Replace

sendBroadcast(intent);

With

localBroadcastManager.sendBroadcast(intent);

4) For unregistering broadcast message

Replace

unregisterReceiver(mybroadcast);

With

localBroadcastManager.unregisterReceiver(mybroadcast);

In Swift 3.1 I have added this extension to UIView

import Foundation
import UIKit
import CoreGraphics


extension UIView {
    func gradientOfView(withColours: UIColor...) {

        var cgColours = [CGColor]()

        for colour in withColours {
            cgColours.append(colour.cgColor)
        }
        let grad = CAGradientLayer()
        grad.frame = self.bounds
        grad.colors = cgColours
        self.layer.insertSublayer(grad, at: 0)
    }
}

which I then call with

    class OverviewVC: UIViewController {

        override func viewDidLoad() {
            super.viewDidLoad()

            self.view.gradientOfView(withColours: UIColor.red,UIColor.green, UIColor.blue)

        }
}

Try the following:

Uninstall-Package Newtonsoft.Json -Force

Followed by:

Install-Package Newtonsoft.Json -Version <press tab key for autocomplete>

You can also use a function within stat_summary to calculate the mean and the hjust argument to place the text, you need a additional function but no additional data frame:

fun_mean <- function(x){
  return(data.frame(y=mean(x),label=mean(x,na.rm=T)))}


ggplot(PlantGrowth,aes(x=group,y=weight)) +
geom_boxplot(aes(fill=group)) +
stat_summary(fun.y = mean, geom="point",colour="darkred", size=3) +
stat_summary(fun.data = fun_mean, geom="text", vjust=-0.7)

I use this:

public static bool ToBoolean(this string input)
        {
            //Account for a string that does not need to be processed
            if (string.IsNullOrEmpty(input))
                return false;

            return (input.Trim().ToLower() == "true") || (input.Trim() == "1");
        }

If you're stuck with pre-5.10, then the solutions provided above will not fully replicate the say function. For example

sub say { print @_, "\n"; }

Will not work with invocations such as

say for @arr;

or

for (@arr) {
    say;
}

... because the above function does not act on the implicit global $_ like print and the real say function.

To more closely replicate the perl 5.10+ say you want this function

sub say {
    if (@_) { print @_, "\n"; }
    else { print $_, "\n"; }
}

Which now acts like this

my @arr = qw( alpha beta gamma );
say @arr;
# OUTPUT
# alphabetagamma
#
say for @arr;
# OUTPUT
# alpha
# beta
# gamma
#

The say builtin in perl6 behaves a little differently. Invoking it with say @arr or @arr.say will not just concatenate the array items, but instead prints them separated with the list separator. To replicate this in perl5 you would do this

sub say {
    if (@_) { print join($", @_) . "\n"; }
    else { print $_ . "\n"; }
}

$" is the global list separator variable, or if you're using English.pm then is is $LIST_SEPARATOR

It will now act more like perl6, like so

say @arr;
# OUTPUT
# alpha beta gamma
#

do like this

set classpath=%classpath%(ur jarfile);

Various ways to make a singleton object:

1. As per Joshua Bloch - Enum would be the best.

2. You can use double check locking also.

3. Even an inner static class can be used.

Something like that should be what you need

private void button1_Click(object sender, RoutedEventArgs e)
{
    // Create OpenFileDialog 
    Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();



    // Set filter for file extension and default file extension 
    dlg.DefaultExt = ".png";
    dlg.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"; 


    // Display OpenFileDialog by calling ShowDialog method 
    Nullable<bool> result = dlg.ShowDialog();


    // Get the selected file name and display in a TextBox 
    if (result == true)
    {
        // Open document 
        string filename = dlg.FileName;
        textBox1.Text = filename;
    }
}

Yes. From the DTD

<!ELEMENT table
     (caption?, (col*|colgroup*), thead?, tfoot?, (tbody+|tr+))>

So it expects one or more. It then goes on to say

Use multiple tbody sections when rules are needed between groups of table rows.

Use like this:

when(
  fooDao.getBar(
    Matchers.<Bazoo>any()
  )
).thenReturn(myFoo);

Before you need to import Mockito.Matchers

Firstly Strings are immutable in java, you have to assign the result of the replace to a variable.

fieldName = fieldName.replace("watever","");

You can use also use regex as an option using String#replaceAll(regex, str);

fieldName = fieldName.replaceAll(",$","");

iframe have "sandbox" attribute that may block pop up etc

For a String constant you have no choice other than escaping via backslash.

Maybe you find the MyBatis project interesting. It is a thin layer over JDBC where you can externalize your SQL queries in XML configuration files without the need to escape double quotes.

Careful when doing a Find Loop that you don't get yourself into an infinite loop... Reference the first found cell address and compare after each "FindNext" statement to make sure it hasn't returned back to the first initially found cell.

RxJS6 (without compatibility package installed)

There's now an EMPTY constant and an empty function.

  import { Observable, empty, of } from 'rxjs';

  var delay = empty().pipe(delay(1000));     
  var delay2 = EMPTY.pipe(delay(1000));

Observable.empty() doesn't exist anymore.

How about:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    row.parentNode.removeChild(row);
}

And, if that fails, this should really work:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    var table = row.parentNode;
    while ( table && table.tagName != 'TABLE' )
        table = table.parentNode;
    if ( !table )
        return;
    table.deleteRow(row.rowIndex);
}

You can use the build job step from Jenkins Pipeline (Minimum Jenkins requirement: 2.130).

Here's the full API for the build step: https://jenkins.io/doc/pipeline/steps/pipeline-build-step/

How to use build:

• job: Name of a downstream job to build. May be another Pipeline job, but more commonly a freestyle or other project.
  • Use a simple name if the job is in the same folder as this upstream Pipeline job;
  • You can instead use relative paths like ../sister-folder/downstream
  • Or you can use absolute paths like /top-level-folder/nested-folder/downstream

Trigger another job using a branch as a param

At my company many of our branches include "/". You must replace any instances of "/" with "%2F" (as it appears in the URL of the job).

In this example we're using relative paths

    stage('Trigger Branch Build') {
        steps {
            script {
                    echo "Triggering job for branch ${env.BRANCH_NAME}"
                    BRANCH_TO_TAG=env.BRANCH_NAME.replace("/","%2F")
                    build job: "../my-relative-job/${BRANCH_TO_TAG}", wait: false
            }
        }
    }

Trigger another job using build number as a param

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

Trigger many jobs in parallel

Source: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/

More info on Parallel here: https://jenkins.io/doc/book/pipeline/syntax/#parallel

    stage ('Trigger Builds In Parallel') {
        steps {
            // Freestyle build trigger calls a list of jobs
            // Pipeline build() step only calls one job
            // To run all three jobs in parallel, we use "parallel" step
            // https://jenkins.io/doc/pipeline/examples/#jobs-in-parallel
            parallel (
                linux: {
                    build job: 'full-build-linux', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                mac: {
                    build job: 'full-build-mac', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                windows: {
                    build job: 'full-build-windows', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                failFast: false)
        }
    }

Or alternatively:

    stage('Build A and B') {
            failFast true
            parallel {
                stage('Build A') {
                    steps {
                            build job: "/project/A/${env.BRANCH}", wait: true
                    }
                }
                stage('Build B') {
                    steps {
                            build job: "/project/B/${env.BRANCH}", wait: true
                    }
                }
            }
    }

That is the mode with which you are opening the file. "wb" means that you are writing to the file (w), and that you are writing in binary mode (b).

Check out the documentation for more: clicky

I would also trim the input field, cause a space could make it look like filled

if ($.trim($('#person_data[document_type]').val()) != '')
{

}

A fun way to do it with pure JDK, in one duty line:

String[] array = new String[] { "Bill", "Bob", "Steve","[Bill]","1,2,3","Apple ][" };
String join = " and ";

String joined = Arrays.toString(array).replaceAll(", ", join)
        .replaceAll("(^\\[)|(\\]$)", "");

System.out.println(joined);

Output:

Bill and Bob and Steve and [Bill] and 1,2,3 and Apple ][

A not too perfect & not too fun way!

String[] array = new String[] { "7, 7, 7","Bill", "Bob", "Steve", "[Bill]",
        "1,2,3", "Apple ][" };
String join = " and ";

for (int i = 0; i < array.length; i++) array[i] = array[i].replaceAll(", ", "~,~");
String joined = Arrays.toString(array).replaceAll(", ", join)
        .replaceAll("(^\\[)|(\\]$)", "").replaceAll("~,~", ", ");

System.out.println(joined);

Output:

7, 7, 7 and Bill and Bob and Steve and [Bill] and 1,2,3 and Apple ][

You can use for it the is operator. You can then check if object is specific type by writing:

if (myObject is string)
{
  DoSomething()
}

You can use GREATEST function with not nullable fields. If one of this values (or both) can be NULL, don't use it (result can be NULL).

select 
    if(
        fieldA is NULL, 
        if(fieldB is NULL, NULL, fieldB), /* second NULL is default value */
        if(fieldB is NULL, field A, GREATEST(fieldA, fieldB))
    ) as maxValue

You can change NULL to your preferred default value (if both values is NULL).

You can add listener all video events nicluding ended, loadedmetadata, timeupdate where ended function gets called when video ends

$("#myVideo").on("ended", function() {_x000D_
   //TO DO: Your code goes here..._x000D_
      alert("Video Finished");_x000D_
});_x000D_
_x000D_
$("#myVideo").on("loadedmetadata", function() {_x000D_
      alert("Video loaded");_x000D_
  this.currentTime = 50;//50 seconds_x000D_
   //TO DO: Your code goes here..._x000D_
});_x000D_
_x000D_
_x000D_
$("#myVideo").on("timeupdate", function() {_x000D_
  var cTime=this.currentTime;_x000D_
  if(cTime>0 && cTime % 2 == 0)//Alerts every 2 minutes once_x000D_
      alert("Video played "+cTime+" minutes");_x000D_
   //TO DO: Your code goes here..._x000D_
  var perc=cTime * 100 / this.duration;_x000D_
  if(perc % 10 == 0)//Alerts when every 10% watched_x000D_

Just a slight addition to the above solution if you are having problem with downloaded file's name...

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.Name + "\"");

This will return the exact file name even if it contains spaces or other characters.

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

SET STATISTICS TIME ON

SELECT * 

FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;

SET STATISTICS TIME OFF;

And see the message tab it will look like this:

SQL Server Execution Times:

   CPU time = 0 ms,  elapsed time = 10 ms.

(778 row(s) affected)

SQL Server parse and compile time: 

   CPU time = 0 ms, elapsed time = 0 ms.

Use directly

$paymentDate = strtotime(date("d-m-Y"));
$contractDateBegin = strtotime("01-01-2001");
$contractDateEnd = strtotime("01-01-2015");

Then comparison will be ok cause your 01-01-2015 is valid for PHP's 32bit date-range, stated in strtotime's manual.

String interpolation is going to be included with Python 3.6 as specified in PEP 498. You will be able to do this:

name = 'Spongebob Squarepants'
print(f'Who lives in a Pineapple under the sea? \n{name}')

Note that I hate Spongebob, so writing this was slightly painful. :)

Enter the date as a native value 'yyyymmdd' to avoid regional issues:

select cast('17530101' as datetime)

Yes, it would be great if TSQL had MinDate() = '00010101', but no such luck.

Try this $('div').myFunction();

This should work

$(document).ready(function() {
 $('#btnSun').click(function(){
  myFunction();
 });

function myFunction()
{
alert('hi');
}

Just push to the branch that the pull request references. As long as the pull request is still open, it should get updated with any added commits automatically.

The simplest solution:

List<String> list = Files.readAllLines(Paths.get("path/of/text"), StandardCharsets.UTF_8);
String[] a = list.toArray(new String[list.size()]); 

Note that java.nio.file.Files is since 1.7

As a note of caution this answer provided by the user above me is correct.

SharedPreferences preferences = this.getActivity().getSharedPreferences("pref",0);

However, if you attempt to get anything in the fragment before onAttach is called getActivity() will return null.

This is what I use. I do this first query to find the sessions and the users:

select s.sid, s.serial#, p.spid, s.username, s.schemaname
     , s.program, s.terminal, s.osuser
  from v$session s
  join v$process p
    on s.paddr = p.addr
 where s.type != 'BACKGROUND';

This will let me know if there are multiple sessions for the same user. Then I usually check to verify if a session is blocking the database.

SELECT SID, SQL_ID, USERNAME, BLOCKING_SESSION, COMMAND, MODULE, STATUS FROM v$session WHERE BLOCKING_SESSION IS NOT NULL;  

Then I run an ALTER statement to kill a specific session in this format:

ALTER SYSTEM KILL SESSION 'sid,serial#'; 

For example:

ALTER SYSTEM KILL SESSION '314, 2643';

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

For anyone going through this error and you've tried updating versions and making sure effects core is present etc and still scratching your head. Check the documentation for animate() and other syntax.

All I did was write "Linear" instead of "linear" and got the [this.easing] is not a function

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'Linear'); //bad

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'linear'); //good

or:

usleep(NUMBER_OF_MICRO_SECONDS);

Found this question here that seems to ask the same thing: Newline character sequence in CSS 'content' property?

Looks like you can use \A or \00000a to achieve a newline

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

Or put your logic into a tidy little class.

public class PrettyPrintingMap<K, V> {
    private Map<K, V> map;

    public PrettyPrintingMap(Map<K, V> map) {
        this.map = map;
    }

    public String toString() {
        StringBuilder sb = new StringBuilder();
        Iterator<Entry<K, V>> iter = map.entrySet().iterator();
        while (iter.hasNext()) {
            Entry<K, V> entry = iter.next();
            sb.append(entry.getKey());
            sb.append('=').append('"');
            sb.append(entry.getValue());
            sb.append('"');
            if (iter.hasNext()) {
                sb.append(',').append(' ');
            }
        }
        return sb.toString();

    }
}

Usage:

Map<String, String> myMap = new HashMap<String, String>();

System.out.println(new PrettyPrintingMap<String, String>(myMap));

Note: You can also put that logic into a utility method.

If you want to know this, it exists an open source library called aFileDialog that it is an small and easy to use which provides a file picker.

The difference with another file chooser's libraries for Android is that aFileDialog gives you the option to open the file chooser as a Dialog and as an Activity.

It also lets you to select folders, create files, filter files using regular expressions and show confirmation dialogs.

The easiest solution would be to use Wireshark and trace the HTTP tcp flow.

You should place Scanner input = new Scanner (System.in); into the main method rather than creating the input object outside.

If you have a custom/self-signed certificate on server that is not there on device, you can use the below class to load it and use it on client side in Android:

Place the certificate *.crt file in /res/raw so that it is available from R.raw.*

Use below class to obtain an HTTPClient or HttpsURLConnection which will have a socket factory using that certificate :

package com.example.customssl;

import android.content.Context;
import org.apache.http.client.HttpClient;
import org.apache.http.conn.scheme.PlainSocketFactory;

Key points:

1. Certificate objects are generated from .crt files.
2. A default KeyStore is created.
3. keyStore.setCertificateEntry("ca", cert) is adding certificate to key store under alias "ca". You modify the code to add more certificates (intermediate CA etc).
4. Main objective is to generate a SSLSocketFactory which can then be used by HTTPClient or HttpsURLConnection.
5. SSLSocketFactory can be configured further, for example to skip host name verification etc.

A message has a header part and a message body separated by a blank line. The blank line is ALWAYS needed even if there is no message body. The header starts with a command and has additional lines of key value pairs separated by a colon and a space. If there is a message body, it can be anything you want it to be.

Lines in the header and the blank line at the end of the header must end with a carraige return and linefeed pair (see HTTP header line break style) so that's why those lines have \r\n at the end.

A URL has the form of http://host:port/path?query_string

There are two main ways of submitting a request to a website:

• GET: The query string is optional but, if specified, must be reasonably short. Because of this the header could just be the GET command and nothing else. A sample message could be:

  GET /path?query_string HTTP/1.0\r\n
  \r\n
  

• POST: What would normally be in the query string is in the body of the message instead. Because of this the header needs to include the Content-Type: and Content-Length: attributes as well as the POST command. A sample message could be:

  POST /path HTTP/1.0\r\n
  Content-Type: text/plain\r\n
  Content-Length: 12\r\n
  \r\n
  query_string
  

So, to answer your question: if the URL you are interested in POSTing to is http://api.somesite.com/apikey=ARG1&command=ARG2 then there is no body or query string and, consequently, no reason to POST because there is nothing to put in the body of the message and so nothing to put in the Content-Type: and Content-Length:

I guess you could POST if you really wanted to. In that case your message would look like:

POST /apikey=ARG1&command=ARG2 HTTP/1.0\r\n
\r\n

So to send the message the C program needs to:

• create a socket
• lookup the IP address
• open the socket
• send the request
• wait for the response
• close the socket

The send and receive calls won't necessarily send/receive ALL the data you give them - they will return the number of bytes actually sent/received. It is up to you to call them in a loop and send/receive the remainder of the message.

What I did not do in this sample is any sort of real error checking - when something fails I just exit the program. Let me know if it works for you:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */
#include <sys/socket.h> /* socket, connect */
#include <netinet/in.h> /* struct sockaddr_in, struct sockaddr */
#include <netdb.h> /* struct hostent, gethostbyname */

void error(const char *msg) { perror(msg); exit(0); }

int main(int argc,char *argv[])
{
    /* first what are we going to send and where are we going to send it? */
    int portno =        80;
    char *host =        "api.somesite.com";
    char *message_fmt = "POST /apikey=%s&command=%s HTTP/1.0\r\n\r\n";

    struct hostent *server;
    struct sockaddr_in serv_addr;
    int sockfd, bytes, sent, received, total;
    char message[1024],response[4096];

    if (argc < 3) { puts("Parameters: <apikey> <command>"); exit(0); }

    /* fill in the parameters */
    sprintf(message,message_fmt,argv[1],argv[2]);
    printf("Request:\n%s\n",message);

    /* create the socket */
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) error("ERROR opening socket");

    /* lookup the ip address */
    server = gethostbyname(host);
    if (server == NULL) error("ERROR, no such host");

    /* fill in the structure */
    memset(&serv_addr,0,sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    serv_addr.sin_port = htons(portno);
    memcpy(&serv_addr.sin_addr.s_addr,server->h_addr,server->h_length);

    /* connect the socket */
    if (connect(sockfd,(struct sockaddr *)&serv_addr,sizeof(serv_addr)) < 0)
        error("ERROR connecting");

    /* send the request */
    total = strlen(message);
    sent = 0;
    do {
        bytes = write(sockfd,message+sent,total-sent);
        if (bytes < 0)
            error("ERROR writing message to socket");
        if (bytes == 0)
            break;
        sent+=bytes;
    } while (sent < total);

    /* receive the response */
    memset(response,0,sizeof(response));
    total = sizeof(response)-1;
    received = 0;
    do {
        bytes = read(sockfd,response+received,total-received);
        if (bytes < 0)
            error("ERROR reading response from socket");
        if (bytes == 0)
            break;
        received+=bytes;
    } while (received < total);

    if (received == total)
        error("ERROR storing complete response from socket");

    /* close the socket */
    close(sockfd);

    /* process response */
    printf("Response:\n%s\n",response);

    return 0;
}

Like the other answer pointed out, 4096 bytes is not a very big response. I picked that number at random assuming that the response to your request would be short. If it can be big you have two choices:

• read the Content-Length: header from the response and then dynamically allocate enough memory to hold the whole response.
• write the response to a file as the pieces arrive

Additional information to answer the question asked in the comments:

What if you want to POST data in the body of the message? Then you do need to include the Content-Type: and Content-Length: headers. The Content-Length: is the actual length of everything after the blank line that separates the header from the body.

Here is a sample that takes the following command line arguments:

• host
• port
• command (GET or POST)
• path (not including the query data)
• query data (put into the query string for GET and into the body for POST)
• list of headers (Content-Length: is automatic if using POST)

So, for the original question you would run:

a.out api.somesite.com 80 GET "/apikey=ARG1&command=ARG2"

And for the question asked in the comments you would run:

a.out api.somesite.com 80 POST / "name=ARG1&value=ARG2" "Content-Type: application/x-www-form-urlencoded"

Here is the code:

#include <stdio.h> /* printf, sprintf */
#include <stdlib.h> /* exit, atoi, malloc, free */
#include <unistd.h> /* read, write, close */
#include <string.h> /* memcpy, memset */

I have a simple form to submit testimonials, I also was having trouble clearing the form, what I did was after the query is submitted successfully I and before redirecting to another page I cleared the imputs $name =''; ect. The page submitted and redirected with no errors.

Font Squirrel did not work for me. I uploaded a font for conversion to multiple font format for IE support. It performed onversion, which I was able to download. I then uploaded content to my server per specs. I was only either able to get Firefox or IE to work but not both. The solution that worked for me was The Mo Bullet Proofer link above.

baseKey choice;
if (Enum.TryParse("HKEY_LOCAL_MACHINE", out choice)) {
     uint value = (uint)choice;

     // `value` is what you're looking for

} else { /* error: the string was not an enum member */ }

Before .NET 4.5, you had to do the following, which is more error-prone and throws an exception when an invalid string is passed:

(uint)Enum.Parse(typeof(baseKey), "HKEY_LOCAL_MACHINE")

Simple, create multiple accordian div each representating one anchor tag like:

<div>
<div class="accordion">

</div>
<div class="accordion">

</div>
</div>

It adds up some markup. But works like a pro...

URL construction is tricky because different parts of the URL have different rules for what characters are allowed: for example, the plus sign is reserved in the query component of a URL because it represents a space, but in the path component of the URL, a plus sign has no special meaning and spaces are encoded as "%20".

RFC 2396 explains (in section 2.4.2) that a complete URL is always in its encoded form: you take the strings for the individual components (scheme, authority, path, etc.), encode each according to its own rules, and then combine them into the complete URL string. Trying to build a complete unencoded URL string and then encode it separately leads to subtle bugs, like spaces in the path being incorrectly changed to plus signs (which an RFC-compliant server will interpret as real plus signs, not encoded spaces).

In Java, the correct way to build a URL is with the URI class. Use one of the multi-argument constructors that takes the URL components as separate strings, and it'll escape each component correctly according to that component's rules. The toASCIIString() method gives you a properly-escaped and encoded string that you can send to a server. To decode a URL, construct a URI object using the single-string constructor and then use the accessor methods (such as getPath()) to retrieve the decoded components.

Don't use the URLEncoder class! Despite the name, that class actually does HTML form encoding, not URL encoding. It's not correct to concatenate unencoded strings to make an "unencoded" URL and then pass it through a URLEncoder. Doing so will result in problems (particularly the aforementioned one regarding spaces and plus signs in the path).

I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:

<input type="checkbox" ng-model="entity.isChecked">

Whenever the user checks or unchecks the checkbox the entity.isChecked value will change too.

If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.

When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners array. The listeners in this array get called after the model value has been set, avoiding this problem).

<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">

... and in the controller ...

var model = {};
$scope.model = model;

// This property is bound to the checkbox in the table header
model.allItemsSelected = false;

// Fired when an entity in the table is checked
$scope.selectEntity = function () {
    // If any entity is not checked, then uncheck the "allItemsSelected" checkbox
    for (var i = 0; i < model.entities.length; i++) {
        if (!model.entities[i].isChecked) {
            model.allItemsSelected = false;
            return;
        }
    }

    // ... otherwise ensure that the "allItemsSelected" checkbox is checked
    model.allItemsSelected = true;
};

Similarly, the "Check All" checkbox in the header:

<th>
    <input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>

... and ...

// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
    // Loop through all the entities and set their isChecked property
    for (var i = 0; i < model.entities.length; i++) {
        model.entities[i].isChecked = model.allItemsSelected;
    }
};

CSS

What is the best way to... add a CSS class to the <tr> containing the entity to reflect its selected state?

If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr> element to dynamically add or remove the class whenever the entity property changes:

<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">

use async:false attribute along with url and data. this will help to execute ajax call immediately and u can fetch and use data from server.

function functABC(){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        async:false
        success: function(data) {
            return data;
        }
    });
}

I install go launcher on mine, (Windows 8)=> preferences => Screens => Screen orientation => vertical (disable QWE keyboard)

This is not possible with CSS selectors. But you could use two classes instead of one, e.g. status and important instead of status-important.

Use This Code

@echo off
:: Get the current directory

for /f "tokens=* delims=/" %%A in ('cd') do set CURRENT_DIR=%%A

echo CURRENT_DIR%%A 

(echo this To confirm this code works fine)

LocalDate localDate = LocalDate.parse( new SimpleDateFormat("yyyy-MM-dd").format(date) );

Express 4.x

To get a URL parameter's value, use req.params

app.get('/p/:tagId', function(req, res) {
  res.send("tagId is set to " + req.params.tagId);
});

// GET /p/5
// tagId is set to 5

If you want to get a query parameter ?tagId=5, then use req.query

app.get('/p', function(req, res) {
  res.send("tagId is set to " + req.query.tagId);
});

// GET /p?tagId=5
// tagId is set to 5

Express 3.x

URL parameter

app.get('/p/:tagId', function(req, res) {
  res.send("tagId is set to " + req.param("tagId"));
});

// GET /p/5
// tagId is set to 5

Query parameter

app.get('/p', function(req, res) {
  res.send("tagId is set to " + req.query("tagId"));
});

// GET /p?tagId=5
// tagId is set to 5

You have to add attribute newline="\n" to open function like this:

with open('file.csv','w',newline="\n") as out:
    csv_out = csv.writer(out, delimiter =';')

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

Far as I know we can't instantiate an abstract class

There's your error right there. Of course you can instantiate an abstract class.

abstract class Animal {}
class Giraffe : Animal {}
...
Animal animal = new Giraffe();

There's an instance of Animal right there. You instantiate an abstract class by making a concrete class derived from it, and instantiating that. Remember, an instance of a derived concrete class is also an instance of its abstract base class. An instance of Giraffe is also an instance of Animal even if Animal is abstract.

Given that you can instantiate an abstract class, it needs to have a constructor like any other class, to ensure that its invariants are met.

Now, a static class is a class you actually cannot instantiate, and you'll notice that it is not legal to make an instance constructor in a static class.

/// <summary>
/// map properties
/// </summary>
/// <param name="sourceObj"></param>
/// <param name="targetObj"></param>
private void MapProp(object sourceObj, object targetObj)
{
    Type T1 = sourceObj.GetType();
    Type T2 = targetObj.GetType();

    PropertyInfo[] sourceProprties = T1.GetProperties(BindingFlags.Instance | BindingFlags.Public);
    PropertyInfo[] targetProprties = T2.GetProperties(BindingFlags.Instance | BindingFlags.Public);

   foreach (var sourceProp in sourceProprties)
   {
       object osourceVal = sourceProp.GetValue(sourceObj, null);
       int entIndex = Array.IndexOf(targetProprties, sourceProp);
       if (entIndex >= 0)
       {
           var targetProp = targetProprties[entIndex];
           targetProp.SetValue(targetObj, osourceVal);
       }
   }
}

The steps below are for Eclipse Indigo Classic Version.

1. Help->Install New Software...
2. Point to Eclipse Indigo Site, If not available add the site "Indigo - http://download.eclipse.org/releases/indigo"
3. Work with the above site
4. Look at "General Purpose Tools"->Marketplace Client
5. After installing, restart Eclipse and you can find Marketplace in "Help->Eclipse Marketplace..."

getDrawable() is deprecated. now you can use

imageView.setImageDrawable(ContextCompat.getDrawable(this,R.drawable.msg_status_client_read)) 

When you create your Process object set StartInfo appropriately:

var proc = new Process 
{
    StartInfo = new ProcessStartInfo
    {
        FileName = "program.exe",
        Arguments = "command line arguments to your executable",
        UseShellExecute = false,
        RedirectStandardOutput = true,
        CreateNoWindow = true
    }
};

then start the process and read from it:

proc.Start();
while (!proc.StandardOutput.EndOfStream)
{
    string line = proc.StandardOutput.ReadLine();
    // do something with line
}

You can use int.Parse() or int.TryParse() to convert the strings to numeric values. You may have to do some string manipulation first if there are invalid numeric characters in the strings you read.

The best solution I could find was listening to the scroll event on the window and set the scrollTop to the previous scrollTop if the child div was visible.

prevScrollPos = 0
$(window).scroll (ev) ->
    if $('#mydiv').is(':visible')
        document.body.scrollTop = prevScrollPos
    else
        prevScrollPos = document.body.scrollTop

There is a flicker in the background of the child div if you fire a lot of scroll events, so this could be tweaked, but it is hardly noticed and it was sufficient for my use case.

I am guessing you are trying to mix Asp code and JS code and at some point it's breaking or not excusing the binding calls correctly.

Perhaps you can try using a delegate instead. It will cut out the complexity of when to bind the click event.

An example would be:

$('body').delegate('.menu li','click',function(){
   var $li = $(this);

   var shouldAddClass = $li.find('a[href^="www.xyz.com/link1"]').length != 0;

   if(shouldAddClass){
       $li.addClass('active');
   }
});

See if that helps, it uses the Attribute Starts With Selector from jQuery.

Chi

Nesting (and) closures

Using closures for maintaining the scope of variables (in our case, the success callback function parameters) is the natural JavaScript solution. With promises, we can arbitrarily nest and flatten .then() callbacks - they are semantically equivalent, except for the scope of the inner one.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(function(resultB) {
            // more processing
            return // something using both resultA and resultB;
        });
    });
}

Of course, this is building an indentation pyramid. If indentation is getting too large, you still can apply the old tools to counter the pyramid of doom: modularize, use extra named functions, and flatten the promise chain as soon as you don't need a variable any more.
In theory, you can always avoid more than two levels of nesting (by making all closures explicit), in practise use as many as are reasonable.

function getExample() {
    // preprocessing
    return promiseA(…).then(makeAhandler(…));
}
function makeAhandler(…)
    return function(resultA) {
        // some processing
        return promiseB(…).then(makeBhandler(resultA, …));
    };
}
function makeBhandler(resultA, …) {
    return function(resultB) {
        // more processing
        return // anything that uses the variables in scope
    };
}

You can also use helper functions for this kind of partial application, like _.partial from Underscore/lodash or the native .bind() method, to further decrease indentation:

function getExample() {
    // preprocessing
    return promiseA(…).then(handlerA);
}
function handlerA(resultA) {
    // some processing
    return promiseB(…).then(handlerB.bind(null, resultA));
}
function handlerB(resultA, resultB) {
    // more processing
    return // anything that uses resultA and resultB
}

Try this simple function to add an dictionary item if it does not exist or update when it exists:

    public void AddOrUpdateDictionaryEntry(string key, int value)
    {
        if (dict.ContainsKey(key))
        {
            dict[key] = value;
        }
        else
        {
            dict.Add(key, value);
        }
    }

This is the same as dict[key] = value.

for index in a:

This will cause index to take on the values of the elements of a, so using them as indices is not what you want. In Python, we iterate over a container by actually iterating over it.

"But wait", you say, "For each of those elements of a, I need to work with the corresponding element of m. How am I supposed to do that without indices?"

Simple. We transform a and m into a list of pairs (element from a, element from m), and iterate over the pairs. Which is easy to do - just use the built-in library function zip, as follows:

for a_element, m_element in zip(a, m):
  s[a_element] = m_element

To make it work the way you were trying to do it, you would have to get a list of indices to iterate over. This is doable: we can use range(len(a)) for example. But don't do that! That's not how we do things in Python. Actually directly iterating over what you want to iterate over is a beautiful, mind-liberating idea.

what about operator.itemgetter

Not really relevant here. The purpose of operator.itemgetter is to turn the act of indexing into something, into a function-like thing (what we call "a callable"), so that it can be used as a callback (for example, a 'key' for sorting or min/max operations). If we used it here, we'd have to re-call it every time through the loop to create a new itemgetter, just so that we could immediately use it once and throw it away. In context, that's just busy-work.

Nowadays, considering such compilers as Intel C++ which extremely optimizing C code, it is very hard to compete with compilers output.

Can you guys please check this out i think it is awesome and easy to understand.

i = 0
First_Value = 0
Second_Value = 1

while(i < Number):
       if(i <= 1):
                  Next = i
       else:
                  Next = First_Value + Second_Value
                  First_Value = Second_Value
                  Second_Value = Next
       print(Next)
       i = i + 1

print(df.to_csv(sep='\t', index=False))

Or possibly:

print(df.to_csv(columns=['A', 'B', 'C'], sep='\t', index=False))

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();
        return jsonString.toString();
    } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
    }

}

I'm guessing this is a homework question, so you probably want to go here. It has a tutorial explaining linked lists, gives good pseudocode and also has a C++ implementation you can download.

I'd recommend reading through the explanation and understanding the pseudocode before blindly using the implementation. This is a topic that you really should understand in depth if you want to continue on in CS.

For those people using Python, you may consider using Selenium Wire, which can set request headers, as well as provide you with the ability to inspect requests and responses.

from seleniumwire import webdriver  # Import from seleniumwire

# Create a new instance of the Firefox driver (or Chrome)
driver = webdriver.Firefox()

# Create a request interceptor
def interceptor(request):
    del request.headers['Referer']  # Delete the header first
    request.headers['Referer'] = 'some_referer'

# Set the interceptor on the driver
driver.request_interceptor = interceptor

# All requests will now use 'some_referer' for the referer
driver.get('https://mysite')

To calculate gradients, the machine learning community uses Autograd:

"Efficiently computes derivatives of numpy code."

To install:

pip install autograd

Here is an example:

import autograd.numpy as np
from autograd import grad

def fct(x):
    y = x**2+1
    return y

grad_fct = grad(fct)
print(grad_fct(1.0))

It can also compute gradients of complex functions, e.g. multivariate functions.

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

For firefox links appear to be "special". The only way I was able to get this working was to use the createEvent described here on MDN and call the initMouseEvent function. Even that didn't work completely, I had to manually tell the browser to open a link...

var theEvent = document.createEvent("MouseEvent");
theEvent.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
var element = document.getElementById('link');
element.dispatchEvent(theEvent);

while (element)
{
    if (element.tagName == "A" && element.href != "")
    {
        if (element.target == "_blank") { window.open(element.href, element.target); }
        else { document.location = element.href; }
        element = null;
    }
    else
    {
        element = element.parentElement;
    }
}

If you have downloaded pio-3.17 On eclipse: right click on the project folder -> build path -> configure build path -> libraries -> add external jars -> add all the commons jar file from the "lib". It's worked for me.

I edit Mark Rajcok's focusMe directive to work for multiple focus in one element.

HTML:

<input  focus-me="myInputFocus"  type="text">

in AngularJs Controller:

$scope.myInputFocus= true;

AngulaJS Directive:

app.directive('focusMe', function ($timeout, $parse) {
    return {
        link: function (scope, element, attrs) {
            var model = $parse(attrs.focusMe);
            scope.$watch(model, function (value) {
                if (value === true) {
                    $timeout(function () {
                        scope.$apply(model.assign(scope, false));
                        element[0].focus();
                    }, 30);
                }
            });
        }
    };
});

Handlebars now supports {{else if}} as of 3.0.0. Therefore, your code should now work.

You can see an example under "conditionals" (slightly revised here with an added {{else}}:

    {{#if isActive}}
      <img src="star.gif" alt="Active">
    {{else if isInactive}}
      <img src="cry.gif" alt="Inactive">
    {{else}}
      <img src="default.gif" alt="default">
    {{/if}}

Note, that file path does not have to be in second column of svn st output. For example if you modify file, and modify it's property, it will be 3rd column.

See possible output examples in:

svn help st

Example output:

 M     wc/bar.c
A  +   wc/qax.c

I suggest to cut first 8 characters by:

svn st | cut -c8- | while read FILE; do echo whatever with "$FILE"; done

If you want to be 100% sure, and deal with fancy filenames with white space at the end for example, you need to parse xml output:

svn st --xml | grep -o 'path=".*"' | sed 's/^path="//; s/"$//'

Of course you may want to use some real XML parser instead of grep/sed.

Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote:

git ls-remote --tags /url/to/upstream/repo

(as illustrated in "When listing git-ls-remote why there's “^{}” after the tag name?")

xbmono illustrates in the comments that quotes are needed:

git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"

Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):

git push --follow-tags

See Push git commits & tags simultaneously.

Regarding Atlassian SourceTree specifically:

Note that, from this thread, SourceTree ONLY shows local tags.

There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015 since Dec. 2015.

A simple workaround:

see a list of only unpushed tags?

git push --tags

or check the "Push all tags" box on the "Push" dialog box, all tags will be pushed to your remote.

That way, you will be "sure that they are present in remote so that other developers can pull them".

That code doesn't work very well i fixed it a little bit

var el = $('.caja-pago');
var elpos_original = el.offset().top;

 $(window).scroll(function(){
     var elpos = el.offset().top;
     var windowpos = $(window).scrollTop();
     var finaldestination = windowpos;
     if(windowpos<elpos_original) {
         finaldestination = elpos_original;
         el.stop().animate({'top':400},500);
     } else {
         el.stop().animate({'top':windowpos+10},500);
     }
 });

Eclipse Link, for many reasons, but notably I feel like it has less bloat than other main stream solutions (at least less in-your-face bloat).

Oh and Eclipse Link has been chosen to be the reference implementation for JPA 2.0

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

You can also go into the directory where you have your pip.exe or pip3.exe located. For me it was on my D drive so here is what I did:

D:\>cd python

D:\python>cd Scripts

D:\python\Scripts>pip3.exe install tweepy

Hope it helps

I would turn it into CSV form, like so:

$string_version = implode(',', $original_array)

You can turn it back by doing:

$destination_array = explode(',', $string_version)

      }
     else 
     {
     $("button").html("Hide");

      }

       });

   });

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

If you're using underscore, you can use bind.

E.g.

if (this.options.destroyOnHide) {
     setTimeout(_.bind(this.tip.destroy, this), 1000);
}

It's not possible using CSS, but using a CSS preprocessor like less or SASS.

From PostreSQL 9.2 Range Types are supported. So you can write this like:

SELECT user_id
FROM user_logs
WHERE '[2014-02-01, 2014-03-01]'::daterange @> login_date

this should be more efficient than the string comparison

From Java Tips: Difference between ear jar and war files:

These files are simply zipped files using the java jar tool. These files are created for different purposes. Here is the description of these files:

• .jar files: The .jar files contain libraries, resources and accessories files like property files.

• .war files: The war file contains the web application that can be deployed on any servlet/jsp container. The .war file contains jsp, html, javascript and other files necessary for the development of web applications.

Official Sun/Oracle descriptions:

• The J2EETM Tutorial: Web Application Archives
• The Java Archive (JAR) File Format: The Basics

Wikipedia articles:

• WAR file format (Sun)
• JAR file

I got it working by this:

if ($request->getMethod() == 'POST') {
    $username = $request->request->get('username');
    $password = $request->request->get('password');

    // Do something with the post data
}

You need to have the Request $request as a parameter in the function too! Hope this helps.

you can use this code as replacement for table align

table 
{
    margin:auto;
}

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

I have a python 2 and python 3 version of this code. I know that the question was asked for python 2 but now (8 years later lol) people will probably be using python 3.

Python 3 Code:

import random
number = str(random.randint(1, 10000000))
comma_placement = 4
print('The original number is: {}. '.format(number))
while True:
    if len(number) % 3 == 0:
        for i in range(0, len(number) // 3 - 1):
            number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
            comma_placement = comma_placement + 4
    else:
        for i in range(0, len(number) // 3):
            number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
    break
print('The new and improved number is: {}'.format(number))        

Python 2 Code: (Edit. The python 2 code isn't working. I am thinking that the syntax is different).

import random
number = str(random.randint(1, 10000000))
comma_placement = 4
print 'The original number is: %s.' % (number)
while True:
    if len(number) % 3 == 0:
        for i in range(0, len(number) // 3 - 1):
            number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
            comma_placement = comma_placement + 4
    else:
        for i in range(0, len(number) // 3):
            number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
    break
print 'The new and improved number is: %s.' % (number) 

You can't compare a specific point in time (such as "right now") against an unfixed, recurring event (8am happens every day).

You can check if now is before or after today's 8am:

>>> import datetime
>>> now = datetime.datetime.now()
>>> today8am = now.replace(hour=8, minute=0, second=0, microsecond=0)
>>> now < today8am
True
>>> now == today8am
False
>>> now > today8am
False

DateTime values should be inserted as if they are strings surrounded by single quotes '20201231' but in many cases they need to be casted explicitly to datetime CAST(N'20201231' AS DATETIME) to avoid bad execution plans with CONVERSION_IMPLICIT warnings that affect negatively the performance. Hier is an example:

CREATE TABLE dbo.T(D DATETIME)

--wrong way
INSERT INTO dbo.T (D) VALUES ('20201231'), ('20201231')

--better way
INSERT INTO dbo.T (D) VALUES (CAST(N'20201231' AS DATETIME)), (CAST(N'20201231' AS DATETIME))

This seems to be clean.

public enum Plane{

/**
 * BOEING_747 plane.
 */
BOEING_747("BOEING_747"),

/**
 * AIRBUS_A380 Plane.
 */
AIRBUS_A380("AIRBUS_A380"),

;

private final String plane;       

private Plane(final String plane) {
    this.plane= plane;
}

Plane(){ 
    plane=null; 
}


/**
 * toString method.
 * 
 * @return Value of this Enum as String.
 */
@Override
public String toString(){
   return plane;
}

/**
 * This method add support to compare Strings with the equalsIgnoreCase String method.
 * 
 * Replicated functionality of the equalsIgnorecase of the java.lang.String.class
 * 
 * @param value String to test.
 * @return True if equal otherwise false.
 */
public boolean equalsIgnoreCase(final String value){
    return plane.equalsIgnoreCase(value);
}

And then in main code:

String airplane="BOEING_747";

if(Plane.BOEING_747.equalsIgnoreCase(airplane)){
     //code
}

You can also try this approach..

public static <E> E[] pickRandom_(int n,E ...item) {
        List<E> copy = Arrays.asList(item);
        Collections.shuffle(copy);
        if (copy.size() > n) {
            return (E[]) copy.subList(0, n).toArray();
        } else {
            return (E[]) copy.toArray();
        }

    }

Whenever we are trying to connect to URL,

if server at the other site is running on https protocol and is mandating that we should communicate via information provided in certificate then we have following option:

1) ask for the certificate(download the certificate), import this certificate in trustore. Default trustore java uses can be found in \Java\jdk1.6.0_29\jre\lib\security\cacerts, then if we retry to connect to the URL connection would be accepted.

2) In normal business cases, we might be connecting to internal URLS in organizations and we know that they are correct. In such cases, you trust that it is the correct URL, In such cases above, code can be used which will not mandate to store the certificate to connect to particular URL.

for the point no 2 we have to follow below steps :

1) write below method which sets HostnameVerifier for HttpsURLConnection which returns true for all cases meaning we are trusting the trustStore.

  // trusting all certificate 
 public void doTrustToCertificates() throws Exception {
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    public X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }

                    public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        return;
                    }

                    public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {
                        return;
                    }
                }
        };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HostnameVerifier hv = new HostnameVerifier() {
            public boolean verify(String urlHostName, SSLSession session) {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost())) {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
    }

2) write below method, which calls doTrustToCertificates before trying to connect to URL

    // connecting to URL
    public void connectToUrl(){
     doTrustToCertificates();//  
     URL url = new URL("https://www.example.com");
     HttpURLConnection conn = (HttpURLConnection)url.openConnection(); 
     System.out.println("ResponseCode ="+conn.getResponseCode());
   }

This call will return response code = 200 means connection is successful.

For more detail and sample example you can refer to URL.

$("#yourdivid textarea, #yourdivid input, #yourdivid select").attr('disabled',true);

you can use localStorage for storing the json data:

the example is given below:-

let JSONDatas = [
    {"id": "Open"},
    {"id": "OpenNew", "label": "Open New"},
    {"id": "ZoomIn", "label": "Zoom In"},
    {"id": "ZoomOut", "label": "Zoom Out"},
    {"id": "Find", "label": "Find..."},
    {"id": "FindAgain", "label": "Find Again"},
    {"id": "Copy"},
    {"id": "CopyAgain", "label": "Copy Again"},
    {"id": "CopySVG", "label": "Copy SVG"},
    {"id": "ViewSVG", "label": "View SVG"}
]

localStorage.setItem("datas", JSON.stringify(JSONDatas));

let data = JSON.parse(localStorage.getItem("datas"));

console.log(data);

Aside from the clear: both hack, you can skip the extra element and use overflow: hidden on the wrapping div:

<div style="overflow: hidden;">
    <div style="float: left;"></div>
    <div style="float: left;"></div>
</div>

Short Answer:

You likely want to use gpg instead of openssl so see "Additional Notes" at the end of this answer. But to answer the question using openssl:

To Encrypt:

openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data

To Decrypt:

openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

Long Answer:

Your best source of information for openssl enc would probably be: https://www.openssl.org/docs/man1.1.1/man1/enc.html

Command line: openssl enc takes the following form:

openssl enc -ciphername [-in filename] [-out filename] [-pass arg]
[-e] [-d] [-a/-base64] [-A] [-k password] [-kfile filename] 
[-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p] [-P] 
[-bufsize number] [-nopad] [-debug] [-none] [-engine id]

Explanation of most useful parameters with regards to your question:

-e
    Encrypt the input data: this is the default.

-d    
    Decrypt the input data.

-k <password>
    Only use this if you want to pass the password as an argument. 
    Usually you can leave this out and you will be prompted for a 
    password. The password is used to derive the actual key which 
    is used to encrypt your data. Using this parameter is typically
    not considered secure because your password appears in 
    plain-text on the command line and will likely be recorded in 
    bash history.

-kfile <filename>
    Read the password from the first line of <filename> instead of
    from the command line as above.

-a
    base64 process the data. This means that if encryption is taking 
    place the data is base64 encoded after encryption. If decryption 
    is set then the input data is base64 decoded before being 
    decrypted.
    You likely DON'T need to use this. This will likely increase the
    file size for non-text data. Only use this if you need to send 
    data in the form of text format via email etc.

-salt
    To use a salt (randomly generated) when encrypting. You always
    want to use a salt while encrypting. This parameter is actually
    redundant because a salt is used whether you use this or not 
    which is why it was not used in the "Short Answer" above!

-K key    
    The actual key to use: this must be represented as a string
    comprised only of hex digits. If only the key is specified, the
    IV must additionally be specified using the -iv option. When 
    both a key and a password are specified, the key given with the
    -K option will be used and the IV generated from the password 
    will be taken. It probably does not make much sense to specify 
    both key and password.

-iv IV
    The actual IV to use: this must be represented as a string 
    comprised only of hex digits. When only the key is specified 
    using the -K option, the IV must explicitly be defined. When a
    password is being specified using one of the other options, the 
    IV is generated from this password.

-md digest
    Use the specified digest to create the key from the passphrase.
    The default algorithm as of this writing is sha-256. But this 
    has changed over time. It was md5 in the past. So you might want
    to specify this parameter every time to alleviate problems when
    moving your encrypted data from one system to another or when
    updating openssl to a newer version.

Additional Notes:

Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups?

To use GPG to do the same you would use the following commands:

To Encrypt:

gpg --output encrypted.data --symmetric --cipher-algo AES256 un_encrypted.data

To Decrypt:

gpg --output un_encrypted.data --decrypt encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

With docker data volumes it's very easy to expose xorg's unix domain socket inside the container.

For example, with a Dockerfile like this:

FROM debian
RUN apt-get update
RUN apt-get install -qqy x11-apps
ENV DISPLAY :0
CMD xeyes

You could do the following:

$ docker build -t xeyes - < Dockerfile
$ XSOCK=/tmp/.X11-unix/X0
$ docker run -v $XSOCK:$XSOCK xeyes

This of course is essentially the same as X-forwarding. It grants the container full access to the xserver on the host, so it's only recommended if you trust what's inside.

Note: If you are concerned about security, a better solution would be to confine the app with mandatory- or role-based-access control. Docker achieves pretty good isolation, but it was designed with a different purpose in mind. Use AppArmor, SELinux, or GrSecurity, which were designed to address your concern.

Another pure Java variation:

public boolean isWithin30Days(Calendar queryCalendar) {

    // 1. Take the date you are checking, and roll it back N days
    Calendar queryCalMinus30Days = Calendar.getInstance();
    queryCalMinus30Days.setTime(queryCalendar.getTime());
    queryCalMinus30Days.add(Calendar.DATE, -30); // subtract 30 days from the calendar

    // 2. Get respective milliseconds for the two Calendars: now & queryCal minus N days 
    long nowL = Calendar.getInstance().getTimeInMillis();
    long queryCalMinus30DaysL = queryCalMinus30Days.getTimeInMillis();

    // 3. if nowL is still less than the queryCalMinus30DaysL, it means queryCalendar is more than 30 days into future
    boolean isWithin30Days = nowL >= queryCalMinus30DaysL;

    return isWithin30Days;
}

This works in Oracle:

insert into pager (PAG_ID,PAG_PARENT,PAG_NAME,PAG_ACTIVE)
          select 8000,0,'Multi 8000',1 from dual
union all select 8001,0,'Multi 8001',1 from dual

The thing to remember here is to use the from dual statement.

Put your test in the same package, but a different source folder (src/main/java vs. src/test/java) and make those methods package-private. Imo testability is more important than privacy.

You can add nulls to the ArrayList, and you will have to check for nulls in the loop:

for(Item i : itemList) {
   if (i != null) {

   }
}

itemsList.size(); would take the null into account.

 List<Integer> list = new ArrayList<Integer>();
 list.add(null);
 list.add (5);
 System.out.println (list.size());
 for (Integer value : list) {
   if (value == null)
       System.out.println ("null value");
   else 
       System.out.println (value);
 }

Output :

2
null value
5

Use these 4 simple commands

Step 1 : git checkout <branch_name>

This is obvious to go into that branch.

Step 2 : git pull -s recursive -X theirs

Take remote branch changes and replace with their changes if conflict arise. Here if you do git status you will get something like this your branch is ahead of 'origin/master' by 3 commits.

Step 3 : git reset --hard origin/<branch_name>

Step 4 : git fetch

Hard reset your branch.

Enjoy.

Selection is its own object within VBA. It functions much like a Range object.

Selection and Range do not share all the same properties and methods, though, so for ease of use it might make sense just to create a range and set it equal to the Selection, then you can deal with it programmatically like any other range.

Dim myRange as Range
Set myRange = Selection

The very simple "catch all" solution is this:

System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

The solution from sebastian-castaldi is a bit more detailed.

I found a solution that may be a bit of an edge case and I didn't try it on other OS than Windows 10, but I think it's worth noticing.

If you find yourself working with J2V8 and nodejs, you can run a simple javascript function returning you the pid of the java process.

Here is an example:

public static void main(String[] args) {
    NodeJS nodeJS = NodeJS.createNodeJS();
    int pid = nodeJS.getRuntime().executeIntegerScript("process.pid;\n");
    System.out.println(pid);
    nodeJS.release();
}

If you want to do the background explicitly, you must be certain that you draw behind the current elements on the canvas.

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
// Add behind elements.
ctx.globalCompositeOperation = 'destination-over'
// Now draw!
ctx.fillStyle = "blue";
ctx.fillRect(0, 0, canvas.width, canvas.height);

It is not possible at all. Variable names aren't communicated within Java (and might also be removed due to compiler optimizations).

EDIT (related to comments):

If you step back from the idea of having to use it as function parameters, here's an alternative (which I wouldn't use - see below):

public void printFieldNames(Object obj, Foo... foos) {
    List<Foo> fooList = Arrays.asList(foos);
    for(Field field : obj.getClass().getFields()) {
         if(fooList.contains(field.get()) {
              System.out.println(field.getName());
         }
    }
}

There will be issues if a == b, a == r, or b == r or there are other fields which have the same references.

EDIT now unnecessary since question got clarified

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

Would it not be better to use java.util.Observable and java.util.Observer that will cause the table to update?

Try select substr(orderno, 1,2) from shipment;

Try this:

string foo = @"D:\Projects\Some\Kind\Of\Pathproblem\wuhoo.xml";

The problem is that in a string, a \ is an escape character. By using the @ sign you tell the compiler to ignore the escape characters.

You can also get by with escaping the \:

string foo = "D:\\Projects\\Some\\Kind\\Of\\Pathproblem\\wuhoo.xml";

Most of the times these terms Web Server and Application server are used interchangeably.

Following are some of the key differences in features of Web Server and Application Server:

• Web Server is designed to serve HTTP Content. App Server can also serve HTTP Content but is not limited to just HTTP. It can be provided other protocol support such as RMI/RPC
• Web Server is mostly designed to serve static content, though most Web Servers have plugins to support scripting languages like Perl, PHP, ASP, JSP etc. through which these servers can generate dynamic HTTP content.
• Most of the application servers have Web Server as integral part of them, that means App Server can do whatever Web Server is capable of. Additionally App Server have components and features to support Application level services such as Connection Pooling, Object Pooling, Transaction Support, Messaging services etc.
• As web servers are well suited for static content and app servers for dynamic content, most of the production environments have web server acting as reverse proxy to app server. That means while servicing a page request, static contents (such as images/Static HTML) are served by web server that interprets the request. Using some kind of filtering technique (mostly extension of requested resource) web server identifies dynamic content request and transparently forwards to app server

Example of such configuration is Apache Tomcat HTTP Server and Oracle (formerly BEA) WebLogic Server. Apache Tomcat HTTP Server is Web Server and Oracle WebLogic is Application Server.

In some cases the servers are tightly integrated such as IIS and .NET Runtime. IIS is web server. When equipped with .NET runtime environment, IIS is capable of providing application services.

This appears to be a variable naming convention in Node.js control-flow code, where a reference to the next function to execute is given to a callback for it to kick-off when it's done.

See, for example, the code samples here:

• http://blog.mixu.net/2011/02/02/essential-node-js-patterns-and-snippets/

Let's look at the example you posted:

function loadUser(req, res, next) {
  if (req.session.user_id) {
    User.findById(req.session.user_id, function(user) {
      if (user) {
        req.currentUser = user;
        return next();
      } else {
        res.redirect('/sessions/new');
      }
    });
  } else {
    res.redirect('/sessions/new');
  }
}

app.get('/documents.:format?', loadUser, function(req, res) {
  // ...
});

The loadUser function expects a function in its third argument, which is bound to the name next. This is a normal function parameter. It holds a reference to the next action to perform and is called once loadUser is done (unless a user could not be found).

There's nothing special about the name next in this example; we could have named it anything.

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

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

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

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

const express = require("express");

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

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

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

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

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

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

You need to define a route to handle form posts:

const multer = require("multer");

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

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


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

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

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

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

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

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

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

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

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

Using SQL SERVER 2005, you can try

SELECT  i.name AS IndexName,
        OBJECT_NAME(ic.OBJECT_ID) AS TableName,
        COL_NAME(ic.OBJECT_ID,ic.column_id) AS ColumnName
FROM    sys.indexes AS i INNER JOIN 
        sys.index_columns AS ic ON  i.OBJECT_ID = ic.OBJECT_ID
                                AND i.index_id = ic.index_id
WHERE   i.is_primary_key = 1

Quick and dirty work around which did it for me, not actually coloring the icon, but surrounding it with a label or badge in the color you want;

<span class="label-important label"><i class="icon-remove icon-white"></i></span>
<span class="label-success label"><i class="icon-ok icon-white"></i></span>

So to upgrade scikit-learn package, you have to follow below process

Step-1: Open your terminal(Ctrl+Alt+t)

Step-2: Now for checking currently installed packages along with the versions installed on your conda environment by typing conda list

Step-3: Now for upgrade type below command

conda update scikit-learn

Hope it helps!!

Then just Select:

var list = source.Select(s=>new { ID = s.ID, Name = s.Name }).ToList();

(edit) Actually - the names could be inferred in this case, so you could use:

var list = source.Select(s=>new { s.ID, s.Name }).ToList();

which saves a few electrons...

you can also just change your delete to a select *

and test your selection

the records selected will be the same as the ones deleted

you can also wrap your statement in a begin / rollback if you are not sure - test the statement then if all is good remove rollback

for example

SELECT * FROM table WHERE id BETWEEN 79 AND 296

will show all the records matching the where if they are the wants you 'really' want to delete then use

DELETE FROM table WHERE id BETWEEN 79 AND 296

You can also create a trigger / which catches deletes and puts them into a history table

so if you delete something by mistake you can always get it back

(keep your history table records no older than say 6 months or whatever business rules say)

One line version:

String text = ((Spinner)findViewById(R.id.spinner)).getSelectedItem().toString();

UPDATE: You can remove casting if you use SDK 26 (or newer) to compile your project.

String text = findViewById(R.id.spinner).getSelectedItem().toString();

If SQL Server edition is 2005/2008, you can use DMVs to calculate the row count in a table:

-- Shows all user tables and row counts for the current database 
-- Remove is_ms_shipped = 0 check to include system objects 
-- i.index_id < 2 indicates clustered index (1) or hash table (0) 
SELECT o.name, 
 ddps.row_count 
FROM sys.indexes AS i 
 INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID 
 INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID 
 AND i.index_id = ddps.index_id 
WHERE i.index_id < 2 
 AND o.is_ms_shipped = 0 
ORDER BY o.NAME 

For SQL Server 2000 database engine, sysindexes will work, but it is strongly advised to avoid using it in future editions of SQL Server as it may be removed in the near future.

If you want a TRIE implemented as a Python class, here is something I wrote after reading about them:

class Trie:

    def __init__(self):
        self.__final = False
        self.__nodes = {}

    def __repr__(self):
        return 'Trie<len={}, final={}>'.format(len(self), self.__final)

    def __getstate__(self):
        return self.__final, self.__nodes

    def __setstate__(self, state):
        self.__final, self.__nodes = state

    def __len__(self):
        return len(self.__nodes)

    def __bool__(self):
        return self.__final

    def __contains__(self, array):
        try:
            return self[array]
        except KeyError:
            return False

    def __iter__(self):
        yield self
        for node in self.__nodes.values():
            yield from node

    def __getitem__(self, array):
        return self.__get(array, False)

    def create(self, array):
        self.__get(array, True).__final = True

    def read(self):
        yield from self.__read([])

    def update(self, array):
        self[array].__final = True

    def delete(self, array):
        self[array].__final = False

    def prune(self):
        for key, value in tuple(self.__nodes.items()):
            if not value.prune():
                del self.__nodes[key]
        if not len(self):
            self.delete([])
        return self

    def __get(self, array, create):
        if array:
            head, *tail = array
            if create and head not in self.__nodes:
                self.__nodes[head] = Trie()
            return self.__nodes[head].__get(tail, create)
        return self

    def __read(self, name):
        if self.__final:
            yield name
        for key, value in self.__nodes.items():
            yield from value.__read(name + [key])

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

Read this post as a good resource on this implementation/usage. Dynamically creating keys in JavaScript associative array

THanks!

Use SimpleDateFormat as aix suggested to format the current time into a string. You should use a format that does not include / characters etc. I would suggest something like yyyyMMddhhmm

The OP is trying to count the number of properties in a JSON object. This could be done with an incremented temp variable in the iterator, but he seems to want to know the count before the iteration begins. A simple function that meets the need is provided at the bottom of this page.

Here's a cut and paste of the code, which worked for me:

function countProperties(obj) {
  var prop;
  var propCount = 0;

  for (prop in obj) {
    propCount++;
  }
  return propCount;
}

This should work well for a JSON object. For other objects, which may derive properties from their prototype chain, you would need to add a hasOwnProperty() test.

If you are already using the networkx library, then you can implement a tree using that. Otherwise, you can try one of the other answers.

NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.

As 'tree' is another term for a (normally rooted) connected acyclic graph, and these are called 'arborescences' in NetworkX.

You may want to implement a plane tree (aka ordered tree) where each sibling has a unique rank and this is normally done via labelling the nodes.

However, graph language looks different from tree language, and the means of 'rooting' an arborescence is normally done by using a directed graph so, while there are some really cool functions and corresponding visualisations available, it would probably not be an ideal choice if you are not already using networkx.

An example of building a tree:

import networkx as nx
G = nx.Graph()
G.add_edge('A', 'B')
G.add_edge('B', 'C')
G.add_edge('B', 'D')
G.add_edge('A', 'E')
G.add_edge('E', 'F')

The library enables each node to be any hashable object, and there is no constraint on the number of children each node has.

The library also provides graph algorithms related to trees and visualization capabilities.

The --net=host option is used to make the programs inside the Docker container look like they are running on the host itself, from the perspective of the network. It allows the container greater network access than it can normally get.

Normally you have to forward ports from the host machine into a container, but when the containers share the host's network, any network activity happens directly on the host machine - just as it would if the program was running locally on the host instead of inside a container.

While this does mean you no longer have to expose ports and map them to container ports, it means you have to edit your Dockerfiles to adjust the ports each container listens on, to avoid conflicts as you can't have two containers operating on the same host port. However, the real reason for this option is for running apps that need network access that is difficult to forward through to a container at the port level.

For example, if you want to run a DHCP server then you need to be able to listen to broadcast traffic on the network, and extract the MAC address from the packet. This information is lost during the port forwarding process, so the only way to run a DHCP server inside Docker is to run the container as --net=host.

Generally speaking, --net=host is only needed when you are running programs with very specific, unusual network needs.

Lastly, from a security perspective, Docker containers can listen on many ports, even though they only advertise (expose) a single port. Normally this is fine as you only forward the single expected port, however if you use --net=host then you'll get all the container's ports listening on the host, even those that aren't listed in the Dockerfile. This means you will need to check the container closely (especially if it's not yours, e.g. an official one provided by a software project) to make sure you don't inadvertently expose extra services on the machine.

If you don't want to commit, or want to commit later (commit message will still be prepared for you, which you can also edit):

git revert -n <commit>

As of C# 9(.net 5 or .net core 3.1), you may want to use records as it does Value Based Equality.

If you can comment out code and your program still works, then yes, that code was optional.

.strip() with no arguments (or None as the first argument) removes all whitespace at the start and end, including spaces, tabs, newlines and carriage returns. Leaving it in doesn't do any harm, and allows your program to deal with unexpected extra whitespace inserted into the file.

For example, by using .strip(), the following two lines in a file would lead to the same end result:

 foo\tbar \n
foo\tbar\n

I'd say leave it in.
