Try using Response.SetCookie(), because Response.Cookies.Add() can cause multiple cookies to be added, whereas SetCookie will update an existing cookie.

I find that if I specify .row:nth-of-type(..), my other row's elements (for other formatting, etc) also get alternating colours. So rather, I'd define in my css an entirely new class:

.row-striped:nth-of-type(odd){
  background-color: #efefef;
}

.row-striped:nth-of-type(even){
  background-color: #ffffff;
}

So now, the alternating row colours will only apply to the row container, when I specify its class as .row-striped, and not the elements inside the row.

<!-- this entire row container is #efefef -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Field Greens with strawberry vinegrette</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$30/salad</small>
        </div>
    </div>
</div>

<!-- this entire row container is #ffffff -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Greek Salad</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$25/salad</small>
        </div>
    </div>
</div>

First off, BigDecimal.multiply() returns a BigDecimal and you're trying to store that in an int.

Second, it takes another BigDecimal as the argument, not an int.

If you just use the BigDecimal for all variables involved in these calculations, it should work fine.

Open up your git bash and type

echo $HOME

This shall be the same folder as you get when you open your command window (cmd) and type

echo %USERPROFILE%

And – of course – the .ssh folder shall be present on THAT directory.

You should use hash (#) tables, That you actually looking for because variables value will remain till that execution only. e.g. -

declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table

When above two and below two statements execute separately.

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

The error will show because the value of variable lost when you execute the batch of query second time. It definitely gives o/p when you run an entire block of code.

The hash table is the best possible option for storing and retrieving the temporary value. It last long till the parent session is alive.

From cppreference when incrementing iterators:

You should prefer pre-increment operator (++iter) to post-increment operator (iter++) if you are not going to use the old value. Post-increment is generally implemented as follows:

   Iter operator++(int)   {
     Iter tmp(*this); // store the old value in a temporary object
     ++*this;         // call pre-increment
     return tmp;      // return the old value   }

Obviously, it's less efficient than pre-increment.

Pre-increment does not generate the temporary object. This can make a significant difference if your object is expensive to create.

I ran into this problem a lot when attempting to use SVG with react.

I ended up using quite a dirty fix, but it's useful to know this option existed. Below I allow the use of the vector-effect attribute on SVG elements.

import SVGDOMPropertyConfig from 'react/lib/SVGDOMPropertyConfig.js';
import DOMProperty from 'react/lib/DOMProperty.js';

SVGDOMPropertyConfig.Properties.vectorEffect = DOMProperty.injection.MUST_USE_ATTRIBUTE;
SVGDOMPropertyConfig.DOMAttributeNames.vectorEffect = 'vector-effect';

As long as this is included/imported before you start using react, it should work.

Create a folder and create another 2 folders inside it like old and new. add relevant jar files to the folders. then open the first folder using IntelliJ. after that click whatever 2 files do you want to compare and right-click and click compare archives.

Another way you can achieve a pause between animations is to apply a second animation that hides the element for the amount of delay you want. This has the benefit of allowing you to use a CSS easing function like you would normally.

.star {
  animation: shooting-star 1000ms ease-in-out infinite,
    delay-animation 2000ms linear infinite;
}

@keyframes shooting-star {
  0% {
    transform: translate(0, 0) rotate(45deg);
  }

  100% {
    transform: translate(300px, 300px) rotate(45deg);
  }
}

@keyframes delay-animation {
  0% {
    opacity: 1;
  }
  50% {
    opacity: 1;
  }
  50.01% {
    opacity: 0;
  }
  100% {
    opacity: 0;
  }
}

This only works if you want the delay to be a multiple of the animation duration. I used this to make a shower of shooting stars appear more random: https://codepen.io/ericdjohnson/pen/GRpOgVO

It's not true SOAPpy does not work with Python 2.5 - it works, although it's very simple and really, really basic. If you want to talk to any more complicated webservice, ZSI is your only friend.

The really useful demo I found is at http://www.ebi.ac.uk/Tools/webservices/tutorials/python - this really helped me to understand how ZSI works.

I think this is what you're looking for.

List<String> columnData = new List<String>();

using(SqlConnection connection = new SqlConnection("conn_string"))
{
    connection.Open();
    string query = "SELECT Column1 FROM Table1";
    using(SqlCommand command = new SqlCommand(query, connection))
    {
        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                columnData.Add(reader.GetString(0));
            }         
        }
    }
}

Not tested, but this should work fine.

The Address() worksheet function does exactly that. As it's not available through Application.WorksheetFunction, I came up with a solution using the Evaluate() method.

This solution let Excel deals with spaces and other funny characters in the sheet name, which is a nice advantage over the previous answers.

Example:

Evaluate("ADDRESS(" & rng.Row & "," & rng.Column & ",1,1,""" & _
    rng.Worksheet.Name & """)")

returns exactly "Sheet1!$A$1", with a Range object named rng referring the A1 cell in the Sheet1 worksheet.

This solution returns only the address of the first cell of a range, not the address of the whole range ("Sheet1!$A$1" vs "Sheet1!$A$1:$B$2"). So I use it in a custom function:

Public Function AddressEx(rng As Range) As String

    Dim strTmp As String

    strTmp = Evaluate("ADDRESS(" & rng.Row & "," & _
        rng.Column & ",1,1,""" & rng.Worksheet.Name & """)")

    If (rng.Count > 1) Then

        strTmp = strTmp & ":" & rng.Cells(rng.Count) _
            .Address(RowAbsolute:=True, ColumnAbsolute:=True)

    End If

    AddressEx = strTmp

End Function

The full documentation of the Address() worksheet function is available on the Office website: https://support.office.com/en-us/article/ADDRESS-function-D0C26C0D-3991-446B-8DE4-AB46431D4F89

Creating an isolate scope is undesirable. I would avoid using the scope attribute and do something like this. scope:true gives you a new child scope but not isolate. Then use parse to point a local scope variable to the same object the user has supplied to the ngModel attribute.

app.directive('myDir', ['$parse', function ($parse) {
    return {
        restrict: 'EA',
        scope: true,
        link: function (scope, elem, attrs) {
            if(!attrs.ngModel) {return;}
            var model = $parse(attrs.ngModel);
            scope.model = model(scope);
        }
    };
}]);

A nonetype is the type of a None.

See the docs here: https://docs.python.org/2/library/types.html#types.NoneType

@XmlRootElement is not needed for unmarshalling - if one uses the 2 parameter form of Unmarshaller#unmarshall.

So, if instead of doing:

UserType user = (UserType) unmarshaller.unmarshal(new StringReader(responseString));

one should do:

JAXBElement<UserType> userElement = unmarshaller.unmarshal(someSource, UserType.class);
UserType user = userElement.getValue();

The latter code will not require @XmlRootElement annotation at UserType class level.

As a variation on the accepted answer you could also use the change_column_default method in your migrations:

def up
  change_column_default :profiles, :show_attribute, true
end

def down
  change_column_default :profiles, :show_attribute, nil
end

Rails API-docs

You could also do this:

$dump = print_r($variable, true);

If you want to open inside the app itself instead of leaving the app you can import SafariServices and work it out.

import UIKit
import SafariServices

let url = URL(string: "https://www.google.com")
let vc = SFSafariViewController(url: url!)
present(vc, animated: true, completion: nil)

      new AsyncRoute({path: '/demo/:demoKey1/:demoKey2', loader: () => {
      return System.import('app/modules/demo/demo').then(m =>m.demoComponent);
       }, name: 'demoPage'}),
       export class demoComponent {
       onClick(){
            this._router.navigate( ['/demoPage', {demoKey1: "123", demoKey2: "234"}]);
          }
        }

Thanks, I found your answers convincing but in my case, I must use the T properties:

log(n!) = T(n·log n) =>  log(n!) = O(n log n) and log(n!) = O(n log n)

to verify the problem I found this web, where you have all the process explained: http://www.mcs.sdsmt.edu/ecorwin/cs372/handouts/theta_n_factorial.htm

Just use the ES6 find() function in a functional way:

var data=[{name:"Afghanistan",code:"AF"},{name:"Åland Islands",code:"AX"},{name:"Albania",code:"AL"},{name:"Algeria",code:"DZ"}];

let country = data.find(el => el.code === "AL");
// => {name: "Albania", code: "AL"}
console.log(country["name"]);

or Lodash _.find:

var data=[{name:"Afghanistan",code:"AF"},{name:"Åland Islands",code:"AX"},{name:"Albania",code:"AL"},{name:"Algeria",code:"DZ"}];

let country = _.find(data, ["code", "AL"]);
// => {name: "Albania", code: "AL"}
console.log(country["name"]);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

I have had over 8 million files in a single ext3 directory. libc readdir() which is used by find, ls and most of the other methods discussed in this thread to list large directories.

The reason ls and find are slow in this case is that readdir() only reads 32K of directory entries at a time, so on slow disks it will require many many reads to list a directory. There is a solution to this speed problem. I wrote a pretty detailed article about it at: http://www.olark.com/spw/2011/08/you-can-list-a-directory-with-8-million-files-but-not-with-ls/

The key take away is: use getdents() directly -- http://www.kernel.org/doc/man-pages/online/pages/man2/getdents.2.html rather than anything that's based on libc readdir() so you can specify the buffer size when reading directory entries from disk.

I have been hunting around trying to solve this one for a while and none of the suggested updates to bash seemed to be working. What I discovered was that some point my npm root was modified such that it was pointing to a Users/USER_NAME/.node/node_modules while the actual installation of npm was living at /usr/local/lib/node_modules. You can check this by running npm root and npm root -g (for the global installation). To correct the path you can call npm config set prefix /usr/local.

public void AnalyseArray(ArrayList<Integer> array) {
  // Do something
}
...
ArrayList<Integer> A = new ArrayList<Integer>();
AnalyseArray(A);

print

For your own classes, just def a __str__ method

public IList<Splitting> get(Guid companyId, long customrId) {    
    var res=from c in Customers_data_source
            where c.CustomerId = customrId && c.CompanyID == companyId
            from s in Splittings_data_srouce
            where s.CustomerID = c.CustomerID
            select s;

    return res.ToList();

Java EE is actually a collection of technologies and APIs for the Java platform designed to support "Enterprise" Applications which can generally be classed as large-scale, distributed, transactional and highly-available applications designed to support mission-critical business requirements.

In terms of what an employee is looking for in specific techs, it is quite hard to say, because the playing field has kept changing over the last five years. It really is about the class of problems that are being solved more than anything else. Transactions and distribution are key.

As others have said, you can/should prepend the string with @ (though you could also just escape the backslashes), but what they glossed over (that is, didn't bring it up despite making a change related to it) was the fact that, as I recently discovered, using \ at the beginning of a pathname, without . to represent the current directory, refers to the root of the current directory tree.

C:\foo\bar>cd \
C:\>

versus

C:\foo\bar>cd .\
C:\foo\bar>

(Using . by itself has the same effect as using .\ by itself, from my experience. I don't know if there are any specific cases where they somehow would not mean the same thing.)

You could also just leave off the leading .\ , if you want.

C:\foo>cd bar
C:\foo\bar>

In fact, if you really wanted to, you don't even need to use backslashes. Forwardslashes work perfectly well! (Though a single / doesn't alias to the current drive root as \ does.)

C:\>cd foo/bar
C:\foo\bar>

You could even alternate them.

C:\>cd foo/bar\baz
C:\foo\bar\baz>

...I've really gone off-topic here, though, so feel free to ignore all this if you aren't interested.

Commons-net surely. :) Most open source projects use it these days.

I Created this simple program to get HSV Codes in realtime

import cv2
import numpy as np


cap = cv2.VideoCapture(0)

def nothing(x):
    pass
# Creating a window for later use
cv2.namedWindow('result')

# Starting with 100's to prevent error while masking
h,s,v = 100,100,100

# Creating track bar
cv2.createTrackbar('h', 'result',0,179,nothing)
cv2.createTrackbar('s', 'result',0,255,nothing)
cv2.createTrackbar('v', 'result',0,255,nothing)

while(1):

    _, frame = cap.read()

    #converting to HSV
    hsv = cv2.cvtColor(frame,cv2.COLOR_BGR2HSV)

    # get info from track bar and appy to result
    h = cv2.getTrackbarPos('h','result')
    s = cv2.getTrackbarPos('s','result')
    v = cv2.getTrackbarPos('v','result')

    # Normal masking algorithm
    lower_blue = np.array([h,s,v])
    upper_blue = np.array([180,255,255])

    mask = cv2.inRange(hsv,lower_blue, upper_blue)

    result = cv2.bitwise_and(frame,frame,mask = mask)

    cv2.imshow('result',result)

    k = cv2.waitKey(5) & 0xFF
    if k == 27:

For me, the problem was in my IBAction with a UIButton.

When you Ctrl+Drag to create an IBAction from a UIButton, make sure to select "UIButton" from the Type dropdown. The default selection of AnyObject causes the app to crash when you tap on the UIButton.

Step 1: Define attributes in $appends
Step 2: Define accessor for that attributes.
Example:

<?php
...

class Movie extends Model{

    protected $appends = ['cover'];

    //define accessor
    public function getCoverAttribute()
    {
        return json_decode($this->InJson)->cover;
    }

My well intended answer is to use this tiny bit of JS: https://github.com/rhroyston/clock-js

clock.now   --> 1462248501241
clock.time  --> 11:08 PM
clock.weekday   --> monday
clock.day   --> 2
clock.month --> may
clock.year  --> 2016
clock.since(1462245888784)  --> 44 minutes
clock.until(1462255888784)  --> 2 hours
clock.what.time(1462245888784)  --> 10:24 PM
clock.what.weekday(1461968554458)   --> friday
clock.what.day('14622458887 84')    --> 2
clock.what.month(1461968554458) --> april
clock.what.year('1461968554458')    --> 2016
clock.what.time()   --> 11:11 PM
clock.what.weekday('14619685abcd')  -->     clock.js error : expected unix timestamp as argument
clock.unit.seconds  --> 1000
clock.unit.minutes  --> 60000
clock.unit.hours    --> 3600000
clock.unit.days --> 86400000
clock.unit.weeks    --> 604800000
clock.unit.months   --> 2628002880
clock.unit.years    --> 31536000000

See .offset() here in the jQuery doc. It gives the position relative to the document, not to the parent. You perhaps have .offset() and .position() confused. If you want the position in the window instead of the position in the document, you can subtract off the .scrollTop() and .scrollLeft() values to account for the scrolled position.

Here's an excerpt from the doc:

The .offset() method allows us to retrieve the current position of an element relative to the document. Contrast this with .position(), which retrieves the current position relative to the offset parent. When positioning a new element on top of an existing one for global manipulation (in particular, for implementing drag-and-drop), .offset() is the more useful.

To combine these:

var offset = $("selector").offset();
var posY = offset.top - $(window).scrollTop();
var posX = offset.left - $(window).scrollLeft(); 

You can try it here (scroll to see the numbers change): http://jsfiddle.net/jfriend00/hxRPQ/

It worked for me, when I set error_reporting in two places at same time

somewhere in PHP code

ini_set('error_reporting', 30711);

and in .htaccess file

Problem :

Problem 1
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - Installation request for laravel/framework (locked at v5.8.38, required as 5.8.*) -> satisfiable by laravel/framework[v5.8.38].

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Solution :

if you using xampp just remove ' ; ' from

;extension=mbstring

in php.ini , save it, done!

It's a great question, but be warned that you're treading in dangerous waters here. When you're deleting code you will have to make sure you're compiling and testing often.

One great tool come to mind:

NDepend - this tool is just amazing. It takes a little while to grok, and after the first 10 minutes I think most developers just say "Screw it!" and delete the app. Once you get a good feel for NDepend, it gives you amazing insight to how your apps are coupled. Check it out: http://www.ndepend.com/. Most importantly, this tool will allow you to view methods which do not have any direct callers. It will also show you the inverse, a complete call tree for any method in the assembly (or even between assemblies).

Whatever tool you choose, it's not a task to take lightly. Especially if you're dealing with public methods on library type assemblies, as you may never know when an app is referencing them.

What you're looking for is:

if($variable === NULL) {...}

Note the ===.
When use ==, as you did, PHP treats NULL, false, 0, the empty string, and empty arrays as equal.

 Small devices (landscape phones, 576px and up)
@media (min-width: 576px) { 
  #my-content{
   width:100%;
 }

// Medium devices (tablets, 768px and up)
@media (min-width: 768px) { 
  #my-content{
   width:100%;
 }
 }

// Large devices (desktops, 992px and up)
@media (min-width: 992px) { 
display: none;
 }

// Extra large devices (large desktops, 1200px and up)
@media (min-width: 1200px) {
// Havent code only get for more informations 
 } 

This worked for me

.container { 
  overflow: hidden; 
  .... 
} 

#sidebar { 
  margin-bottom: -5000px; /* any large number will do */
  padding-bottom: 5000px; 
  .... 
}

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT

Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.

For the length of 6, recursiveness doesn't matter a lot.

function random(len) {_x000D_
  let result = Math.floor(Math.random() * Math.pow(10, len));_x000D_
_x000D_
  return (result.toString().length < len) ? random(len) : result;_x000D_
}_x000D_
_x000D_
console.log(random(6));

EDIT: Per @sshow's comment, if you're trying to run your node app on port 80, the below is not the best way to do it. Here's a better answer: How do I run Node.js on port 80?

Original Answer:

If you want to do this to run on port 80 (or want to set the env variable more permanently),

1. Open up your bash profile vim ~/.bash_profile
2. Add the environment variable to the file export PORT=80
3. Open up the sudoers config file sudo visudo
4. Add the following line to the file exactly as so Defaults env_keep +="PORT"

Now when you run sudo node app.js it should work as desired.

It's in your home folder but it's hidden by default.

Typing the below commands in the terminal made it visible for me (only the .m2 folder that is, not all the other hidden folders).

> mv ~/.m2 ~/m2
> ln -s ~/m2 ~/.m2

DateTime values in T-SQL are stored as floats. You can just subtract the dates from each other and you now have a new date that is the timespan between them.

declare @birthdate datetime
set @birthdate = '6/15/1974'

--age in years - short version
print year(getdate() - @birthdate) - year(0)

--age in years - visualization
declare @mindate datetime
declare @span datetime

set @mindate = 0
set @span = getdate() - @birthdate

print @mindate
print @birthdate
print getdate()
print @span
--substract minyear from spanyear to get age in years
print year(@span) - year(@mindate)
print month(@span)
print day(@span)

If your mapTypeId is SATELLITE or HYBRID

well, it is just a watermark, you can hide it if you change the <div> that has z-index=100 I use

setInterval(function(){
    $("*").each(function() {
        if ($(this).css("zIndex") == 100) {
            $(this).css("zIndex", "-100");
        }
    })}
, 10);

or you can use

map.addListener('idle', function(e) {
    //same function
}

but it is not as responsive as setInterval

Below UITableViewDataSource will help you for swipe delete

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return YES if you want the specified item to be editable.
    return YES;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [arrYears removeObjectAtIndex:indexPath.row];
        [tableView reloadData];
    }
}

arrYears is a NSMutableArray and then reload the tableView

Swift

 func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
            return true
        }

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == UITableViewCellEditingStyleDelete {
        arrYears.removeObjectAtIndex(indexPath.row)
        tableView.reloadData()
    }
}

I hope this one should work:

Integer.valueOf(mEdit.getText().toString());

I tried Integer.getInteger() method instead of valueOf() - it didn't work.

Okay so you are trying to get a bitmap from a file? Title says URL. Anyways, when you are getting files from external storage in Android you should never use a direct path. Instead call getExternalStorageDirectory() like so:

File bitmapFile = new File(Environment.getExternalStorageDirectory() + "/" + PATH_TO_IMAGE);
Bitmap bitmap = BitmapFactory.decodeFile(bitmapFile);

getExternalStorageDirectory() gives you the path to the SD card. Also you need to declare the WRITE_EXTERNAL_STORAGE permission in the Manifest.

As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx

Template

<form [formGroup]="mainForm" ng-submit="submitForm()">
  Global Price: <input type="number" formControlName="globalPrice">
  <button type="button" [disabled]="mainForm.get('globalPrice').value === null" (click)="applyPriceToAll()">Apply to all</button>
  <table border formArrayName="orderLines">
  <ng-container *ngFor="let orderLine of orderLines let i=index" [formGroupName]="i">
    <tr>
       <td>{{orderLine.time | date}}</td>
       <td>{{orderLine.quantity}}</td>
       <td><input formControlName="price" type="number"></td>
    </tr>
</ng-container>
  </table>
</form>

Component

import { Component } from '@angular/core';
import { FormGroup, FormControl, FormArray } from '@angular/forms';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular 6';
  mainForm: FormGroup;
  orderLines = [
    {price: 10, time: new Date(), quantity: 2},
    {price: 20, time: new Date(), quantity: 3},
    {price: 30, time: new Date(), quantity: 3},
    {price: 40, time: new Date(), quantity: 5}
    ]
  constructor() {
    this.mainForm = this.getForm();
  }

  getForm(): FormGroup {
    return new FormGroup({
      globalPrice: new FormControl(),
      orderLines: new FormArray(this.orderLines.map(this.getFormGroupForLine))
    })
  }

  getFormGroupForLine(orderLine: any): FormGroup {
    return new FormGroup({
      price: new FormControl(orderLine.price)
    })
  }

  applyPriceToAll() {
    const formLines = this.mainForm.get('orderLines') as FormArray;
    const globalPrice = this.mainForm.get('globalPrice').value;
    formLines.controls.forEach(control => control.get('price').setValue(globalPrice));
    // optionally recheck value and validity without emit event.
  }

  submitForm() {

  }
}

About list

First a very important point, from which everything will follow (I hope).

In ordinary Python, list is not special in any way (except having cute syntax for constructing, which is mostly a historical accident). Once a list [3,2,6] is made, it is for all intents and purposes just an ordinary Python object, like a number 3, set {3,7}, or a function lambda x: x+5.

(Yes, it supports changing its elements, and it supports iteration, and many other things, but that's just what a type is: it supports some operations, while not supporting some others. int supports raising to a power, but that doesn't make it very special - it's just what an int is. lambda supports calling, but that doesn't make it very special - that's what lambda is for, after all:).

About and

and is not an operator (you can call it "operator", but you can call "for" an operator too:). Operators in Python are (implemented through) methods called on objects of some type, usually written as part of that type. There is no way for a method to hold an evaluation of some of its operands, but and can (and must) do that.

The consequence of that is that and cannot be overloaded, just like for cannot be overloaded. It is completely general, and communicates through a specified protocol. What you can do is customize your part of the protocol, but that doesn't mean you can alter the behavior of and completely. The protocol is:

Imagine Python interpreting "a and b" (this doesn't happen literally this way, but it helps understanding). When it comes to "and", it looks at the object it has just evaluated (a), and asks it: are you true? (NOT: are you True?) If you are an author of a's class, you can customize this answer. If a answers "no", and (skips b completely, it is not evaluated at all, and) says: a is my result (NOT: False is my result).

If a doesn't answer, and asks it: what is your length? (Again, you can customize this as an author of a's class). If a answers 0, and does the same as above - considers it false (NOT False), skips b, and gives a as result.

If a answers something other than 0 to the second question ("what is your length"), or it doesn't answer at all, or it answers "yes" to the first one ("are you true"), and evaluates b, and says: b is my result. Note that it does NOT ask b any questions.

The other way to say all of this is that a and b is almost the same as b if a else a, except a is evaluated only once.

Now sit for a few minutes with a pen and paper, and convince yourself that when {a,b} is a subset of {True,False}, it works exactly as you would expect of Boolean operators. But I hope I have convinced you it is much more general, and as you'll see, much more useful this way.

Putting those two together

Now I hope you understand your example 1. and doesn't care if mylist1 is a number, list, lambda or an object of a class Argmhbl. It just cares about mylist1's answer to the questions of the protocol. And of course, mylist1 answers 5 to the question about length, so and returns mylist2. And that's it. It has nothing to do with elements of mylist1 and mylist2 - they don't enter the picture anywhere.

Second example: & on list

On the other hand, & is an operator like any other, like + for example. It can be defined for a type by defining a special method on that class. int defines it as bitwise "and", and bool defines it as logical "and", but that's just one option: for example, sets and some other objects like dict keys views define it as a set intersection. list just doesn't define it, probably because Guido didn't think of any obvious way of defining it.

numpy

On the other leg:-D, numpy arrays are special, or at least they are trying to be. Of course, numpy.array is just a class, it cannot override and in any way, so it does the next best thing: when asked "are you true", numpy.array raises a ValueError, effectively saying "please rephrase the question, my view of truth doesn't fit into your model". (Note that the ValueError message doesn't speak about and - because numpy.array doesn't know who is asking it the question; it just speaks about truth.)

For &, it's completely different story. numpy.array can define it as it wishes, and it defines & consistently with other operators: pointwise. So you finally get what you want.

HTH,

In addition to what Tichodroma said, you might end up using this syntax:

outputString=$(python myPythonScript arg1 arg2 arg3)

Lodash has got _.mapValues() which is identical to Underscore.js's _.mapObject().

You need to convert the $old_date back into a timestamp, as the date function requires a timestamp as its second argument.

<!DOCTYPE html>
<html>
<body>
<button onclick="myFunction()">Try it</button>

<script>
function myFunction()
{
    alert("Hello!");
}
</script>

</body>
</html>

Copy Paste this in an HTML file and run in any browser , this should show an alert using javascript.

$('#btnSaveComments').click(function () {
    var comments = $('#txtComments').val();
    var selectedId = $('#hdnSelectedId').val();

    $.ajax({
        url: '<%: Url.Action("SaveComments")%>',
        data: { 'id' : selectedId, 'comments' : comments },
        type: "post",
        cache: false,
        success: function (savingStatu`enter code here`s) {
            $("#hdnOrigComments").val($('#txtComments').val());
            $('#lblCommentsNotification').text(savingStatus);
        },
        error: function (xhr, ajaxOptions, thrownError) {
            $('#lblCommentsNotification').text("Error encountered while saving the comments.");
        }
    });
});

I may be a bit late to the party but this method works for me and is easier than the COALESCE method.

SELECT STUFF(
             (SELECT ',' + Column_Name 
              FROM Table_Name
              FOR XML PATH (''))
             , 1, 1, '')

Regex's aren't really the best tool for the job here. As others have said, using a combination of str.strip() and str.split() is the way to go. Here's a one liner to do it:

>>> data = '''\n\tName: John Smith
... \n\t  Home: Anytown USA
... \n\t    Phone: 555-555-555
... \n\t  Other Home: Somewhere Else
... \n\t Notes: Other data
... \n\tName: Jane Smith
... \n\t  Misc: Data with spaces'''
>>> {line.strip().split(': ')[0]:line.split(': ')[1] for line in data.splitlines() if line.strip() != ''}
{'Name': 'Jane Smith', 'Other Home': 'Somewhere Else', 'Notes': 'Other data', 'Misc': 'Data with spaces', 'Phone': '555-555-555', 'Home': 'Anytown USA'}

I'm very late in the game, but this might help others. I hit this same problem with $.get and I didn't want to blindly turn off caching and I didn't like the timestamp patch. So after a little research I found that you can simply use $.post instead of $.get which does NOT use caching. Simple as that. :)

To simplify Amiram Korach's solution:

dtList.RemoveAll(s => string.IsNullOrWhiteSpace(s))

No need to use Distinct() or ToList()

//a[text()='programming quesions site']/@href 

which basically identifies an anchor node <a> that has the text you want, and extracts the href attribute.

Service vs Factory

The difference between factory and service is just like the difference between a function and an object

Factory Provider

• Gives us the function's return value ie. You just create an object, add properties to it, then return that same object.When you pass this service into your controller, those properties on the object will now be available in that controller through your factory. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Factory are a great way for communicating between controllers like sharing data.

• Can use other dependencies

• Usually used when the service instance requires complex creation logic

• Cannot be injected in .config() function.

• Used for non configurable services

• If you're using an object, you could use the factory provider.

• Syntax: module.factory('factoryName', function);

Service Provider

• Gives us the instance of a function (object)- You just instantiated with the ‘new’ keyword and you’ll add properties to ‘this’ and the service will return ‘this’.When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Services are used for communication between controllers to share data

• You can add properties and functions to a service object by using the this keyword

• Dependencies are injected as constructor arguments

• Used for simple creation logic

• Cannot be injected in .config() function.

• If you're using a class you could use the service provider

• Syntax: module.service(‘serviceName’, function);

Sample Demo

In below example I have define MyService and MyFactory. Note how in .service I have created the service methods using this.methodname. In .factory I have created a factory object and assigned the methods to it.

AngularJS .service

module.service('MyService', function() {

    this.method1 = function() {
            //..method1 logic
        }

    this.method2 = function() {
            //..method2 logic
        }
});

AngularJS .factory

module.factory('MyFactory', function() {

    var factory = {}; 

    factory.method1 = function() {
            //..method1 logic
        }

    factory.method2 = function() {
            //..method2 logic
        }

    return factory;
});

Confused about service vs factory

AngularJS Factory, Service and Provider

Angular.js: service vs provider vs factory?

You cannot do that in Standard C++.

I'm posting this because it is the only correct answer. Your question asks how to do it in C++. Well, you can't do it in C++. You can do it in Windows, POSIX, Linux, Android, but all those are OS-specific solutions and not part of the language standard.

Standard C++ does not have a networking layer at all.

I assume you have this wrong assumption that C++ Standard defines the same scope of features as other language standards, Java. While Java might have built-in networking (and even a GUI framework) in the language's own standard library, C++ does not.

While there are third-party APIs and libraries which can be used by a C++ program, this is in no way the same as saying that you can do it in C++.

Here is an example to clarify what I mean. You can open a file in C++ because it has an fstream class as part of its standard library. This is not the same thing as using CreateFile(), which is a Windows-specific function and available only for WINAPI.

I'm new in R, but I was using this easy method that works for me:

sample_of_diamonds <- diamonds[sample(nrow(diamonds),100),]

PS: Feel free to note if it has some drawback I'm not thinking about.

Several sites provide reasonable cheat sheets or HOWTOs for tables and images. Top on my list are:

• Pandoc readme, specifically tables

• RStudio's RMarkdown, more details in basics (including tables) and a rewrite of pandoc's markdown.

Pictures are very simple to use but do not offer the ability to adjust the image to fit the page (see Update, below). To adjust the image properties (size, resolution, colors, border, etc), you'll need some form of image editor. I find I can do everything I need with one of ImageMagick, GIMP, or InkScape, all free and open source.

To add a picture, use:

![Caption for the picture.](/path/to/image.png)

I know pandoc supports PNG and JPG, which should meet most of your needs.

You do have control over image size if you are creating it in R (e.g., a plot). This can be done either directly in the command to create the image or, even better, via options if you are using knitr (highly recommended ... check out chunk options, specifically under Plots).

I strongly recommend perusing these tutorials; markdown is very handy and has many features most people don't use on a regular basis but really like once they learn it. (SO is not necessarily the best place to ask questions that are answered very directly in these tutorials.)

Update, 2019-Aug-31

Some time ago, pandoc incorporated "link_attributes" for images (apparently in 2015, with commit jgm/pandoc#244cd56). "Resizing images" can be done directly. For example:

![unchanged image](foo.jpg)
![much-smaller image](foo.jpg){#id .class width=30 height=20px}
![half-size image](foo.jpg){#id .class width=50% height=50%}

The dimensions can be provided with no units (pixels assumed), or with "px, cm, mm, in, inch and %" (ref: https://pandoc.org/MANUAL.html, search for link_attributes).

(I'm not certain that CommonMark has implemented this, though there was a lengthy discussion.)

You need additional plugin for this.

take a look at this plugin

There's a definite need to get the last element of a dictionary, for example to confirm whether the latest element has been appended to the dictionary object or not.

We need to convert the dictionary keys to a list object, and use an index of -1 to print out the last element.

mydict = {'John':'apple','Mat':'orange','Jane':'guava','Kim':'apple','Kate': 'grapes'}

mydict.keys()

output: dict_keys(['John', 'Mat', 'Jane', 'Kim', 'Kate'])

list(mydict.keys())

output: ['John', 'Mat', 'Jane', 'Kim', 'Kate']

list(mydict.keys())[-1]

output: 'Kate'

You can do this, I am using

DataTable 1.10.5

using this code:

var versionNo = $.fn.dataTable.version;
alert(versionNo);

This is how I insert new record on my DataTable using row.add (My table has 10 columns), which can also includes HTML tag elements:

function fncInsertNew() {
            var table = $('#tblRecord').DataTable();

            table.row.add([
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "2011/04/25",
                    "Edinburgh",
                    "5421",
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "<p>Hello</p>"
            ]).draw();
        }

For multiple inserts at the same time, use rows.add instead:

var table = $('#tblRecord').DataTable();

table.rows.add( [ {
        "Tiger Nixon",
        "System Architect",
        "$3,120",
        "2011/04/25",
        "Edinburgh",
        "5421"
    }, {
        "Garrett Winters",
        "Director",
        "$5,300",
        "2011/07/25",
        "Edinburgh",
        "8422"
    }]).draw();

If you have a very limited number of levels, you could try converting y into factor and change its levels.

> xy <- data.frame(x = c(1, 2, 4), y = c(1, 4, 5))
> xy$w <- as.factor(xy$y)
> levels(xy$w) <- c("good", "fair", "bad")
> xy
  x y    w
1 1 1 good
2 2 4 fair
3 4 5  bad

contentType: 'application/x-www-form-urlencoded'

If you have N consumers then:

JMS Topics deliver messages to N of N JMS Queues deliver messages to 1 of N

You said you are "looking to have a 'thing' that will send a copy of the message to each subscriber in the same sequence as that in which the message was received by the ActiveMQ broker."

So you want to use a Topic in order that all N subscribers get a copy of the message.

In the build.gradle file for your app module, add this to the defaultConfig section (under the android section). This will write out the schema to a schemas subfolder of your project folder.

javaCompileOptions {
    annotationProcessorOptions {
        arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
    }
}

Like this:

// ...

android {
    
    // ... (compileSdkVersion, buildToolsVersion, etc)

    defaultConfig {

        // ... (applicationId, miSdkVersion, etc)
        
        javaCompileOptions {
            annotationProcessorOptions {
                arguments += ["room.schemaLocation": "$projectDir/schemas".toString()]
            }
        }
    }
   
    // ... (buildTypes, compileOptions, etc)

}

// ...

Also a good script, although my laptop ran out of memory, but this was on a very large table

I needed a multilevel dropdown menu in css. I couldn't find an error-free menu that I searched. Then I created a menu instance using the Css hover transition effect.I hope it will be useful for users.

Css codes:

#AnaMenu {
width: 920px;            /* Menu width */
height: 30px;           /* Menu height */
position: relative;

Using a Temp Table outside of pl/PgSQL

Outside of using pl/pgsql or other pl/* language as suggested, this is the only other possibility I could think of.

begin;
select 5::int as var into temp table myvar;
select *
  from somewhere s, myvar v
 where s.something = v.var;
commit;

Use capital HH to get hour of day format, instead of am/pm hours

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

Nice solutions, but I wonder why nobody is giving the solution for windows.

If you are using windows you just have to "Run as Administrator" the cmd.

I stumbled over the same question and I've found a solution.

First make sure you upgrade to LESS 1.6 at least. You can use npm for that case.

Now you can use the following mixin:

.if (@condition, @property, @value) when (@condition = true){
     @{property}: @value;
 }

Since LESS 1.6 you are able to pass PropertyNames to Mixins as well. So for example you could just use:

.myHeadline {
   .if(@include-lineHeight,  line-height, '35px');
}

If @include-lineheight resolves to true LESS will print the line-height: 35px and it will skip the mixin if @include-lineheight is not true.

Are you trying to make it responsive? If you are then I would just recommend the following:

.tales {
  width: 100%;
}
.carousel-inner{
  width:100%;
  max-height: 200px !important;
}

However, the best way to handle this responsively would be thru the use of media queries like such:

/* Smaller than standard 960 (devices and browsers) */
@media only screen and (max-width: 959px) {}

/* Tablet Portrait size to standard 960 (devices and browsers) */
@media only screen and (min-width: 768px) and (max-width: 959px) {}

/* All Mobile Sizes (devices and browser) */
@media only screen and (max-width: 767px) {}

/* Mobile Landscape Size to Tablet Portrait (devices and browsers) */
@media only screen and (min-width: 480px) and (max-width: 767px) {}

/* Mobile Portrait Size to Mobile Landscape Size (devices and browsers) */
@media only screen and (max-width: 479px) {}

I use this

import android.app.Activity;
import android.support.annotation.StringRes;
import android.widget.Toast;

public class ExitApp {

    private static long lastClickTime;

    public static void now(Activity ctx, @StringRes int message) {
        now(ctx, ctx.getString(message), 2500);
    }

    public static void now(Activity ctx, @StringRes int message, long time) {
        now(ctx, ctx.getString(message), time);
    }

    public static void now(Activity ctx, String message, long time) {
        if (ctx != null && !message.isEmpty() && time != 0) {
            if (lastClickTime + time > System.currentTimeMillis()) {
                ctx.finish();
            } else {
                Toast.makeText(ctx, message, Toast.LENGTH_SHORT).show();
                lastClickTime = System.currentTimeMillis();
            }
        }
    }

}

use to in event onBackPressed

@Override
public void onBackPressed() {
   ExitApp.now(this,"Press again for close");
}

or ExitApp.now(this,R.string.double_back_pressed)

for change seconds need for close, specified miliseconds

ExitApp.now(this,R.string.double_back_pressed,5000)

Try jamspell - it works pretty well for automatic spelling correction:

import jamspell

corrector = jamspell.TSpellCorrector()
corrector.LoadLangModel('en.bin')

corrector.FixFragment('Some sentnec with error')
# u'Some sentence with error'

corrector.GetCandidates(['Some', 'sentnec', 'with', 'error'], 1)
# ('sentence', 'senate', 'scented', 'sentinel')

You have 2 choices:

1) Either specify the column name list (without the identity column).

2) SET IDENTITY_INSERT tablename ON, followed by insert statements that provide explicit values for the identity column, followed by SET IDENTITY_INSERT tablename OFF.

If you are avoiding a column name list, perhaps this 'trick' might help?:

-- Get a comma separated list of a table's column names
SELECT STUFF(
(SELECT 
',' + COLUMN_NAME AS [text()]
FROM 
INFORMATION_SCHEMA.COLUMNS
WHERE 
TABLE_NAME = 'TableName'
Order By Ordinal_position
FOR XML PATH('')
), 1,1, '')

Yet another functional solution for Python 2:

from functools import partial

map(partial(map, int), T1)

Python 3 will be a little bit messy though:

list(map(list, map(partial(map, int), T1)))

we can fix this with a wrapper

def oldmap(f, iterable):
    return list(map(f, iterable))

oldmap(partial(oldmap, int), T1)

You should just use android studio for this process. It is just simpler. But first run this command in your react native app directory:

For Newer version of react-native(e.g. react native 0.49.0 & so on...)

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

For Older Version of react-native (0.49.0 & below)

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

Then Use android studio to open the 'android' folder in you react native app directory, it will ask to upgrade gradle and some other stuff. go to build-> Generate signed APK and follow the instructions from there. It's really straight forward.

It should be:

cursor.execute ("""
   UPDATE tblTableName
   SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
   WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))

You can also do it with basic string manipulation,

cursor.execute ("UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server='%s' " % (Year, Month, Day, Hour, Minute, ServerID))

but this way is discouraged because it leaves you open for SQL Injection. As it's so easy (and similar) to do it the right way^tm. Do it correctly.

The only thing you should be careful, is that some database backends don't follow the same convention for string replacement (SQLite comes to mind).

This works for me:

git fetch
git rebase --autostash FETCH_HEAD

As of in python 3 id is assigned to a value not a variable. This means that if you create two functions as below, all the three id's are the same.

>>> def xyz():
...     q=123
...     print(id(q))
...
>>> def iop():
...     w=123
...     print(id(w))
>>> xyz()
1650376736
>>> iop()
1650376736
>>> id(123)
1650376736

Not with CSS. You could do it with JavaScript easily, though, by canceling the default event handling for those elements. In jQuery:

$('a span:nth-child(2)').click(function(event) { event.preventDefault(); });

You can use PowerShell.

New-Service -Name "TestService" -BinaryPathName "C:\WINDOWS\System32\svchost.exe -k netsvcs"

Refer - https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/new-service?view=powershell-3.0

we can use

 element[role="ourRole"] {
    requried style !important; /*for overriding the old css styles */
    }

Here is my object inspector that is more readable. Because the code takes to long to write down here you can download it at http://etto-aa-js.googlecode.com/svn/trunk/inspector.js

Use like this :

document.write(inspect(object));

    byte[] seed = (SALT2 + username + password).getBytes();
    SecureRandom random = new SecureRandom(seed);
    KeyGenerator generator;
    generator = KeyGenerator.getInstance("AES");
    generator.init(random);
    generator.init(256);
    Key keyObj = generator.generateKey();

My solution is to define a merge function. It's not sophisticated and just cost one line. Here's the code in Python 3.

from functools import reduce
from operator import or_

def merge(*dicts):
    return { k: reduce(lambda d, x: x.get(k, d), dicts, None) for k in reduce(or_, map(lambda x: x.keys(), dicts), set()) }

Tests

>>> d = {0: 0, 1: 1, 2: 4, 3: 9, 4: 16}
>>> d_letters = {0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d, d_letters)
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f', 6: 'g', 7: 'h', 8: 'i', 9: 'j', 10: 'k', 11: 'l', 12: 'm', 13: 'n', 14: 'o', 15: 'p', 16: 'q', 17: 'r', 18: 's', 19: 't', 20: 'u', 21: 'v', 22: 'w', 23: 'x', 24: 'y', 25: 'z', 26: 'A', 27: 'B', 28: 'C', 29: 'D', 30: 'E', 31: 'F', 32: 'G', 33: 'H', 34: 'I', 35: 'J', 36: 'K', 37: 'L', 38: 'M', 39: 'N', 40: 'O', 41: 'P', 42: 'Q', 43: 'R', 44: 'S', 45: 'T', 46: 'U', 47: 'V', 48: 'W', 49: 'X', 50: 'Y', 51: 'Z'}
>>> merge(d_letters, d)

It works for arbitrary number of dictionary arguments. Were there any duplicate keys in those dictionary, the key from the rightmost dictionary in the argument list wins.

Here's your problem:

int latitude = (int) (location.getLatitude());
int longitude = (int) (location.getLongitude());

Latitude and Longitude are double-values, because they represent the location in degrees.

By casting them to int, you're discarding everything behind the comma, which makes a big difference. See "Decimal Degrees - Wiki"

If I remember my QBasic, right, left and mid do something like this:

>>> s = '123456789'
>>> s[-2:]
'89'
>>> s[:2]
'12'
>>> s[4:6]
'56'

If you allow 3rd party libs, you can use Guava's ImmutableMap to achieve literal-like brevity:

Map<String, String> test = ImmutableMap.of("k1", "v1", "k2", "v2");

This works for up to 5 key/value pairs, otherwise you can use its builder:

Map<String, String> test = ImmutableMap.<String, String>builder()
    .put("k1", "v1")
    .put("k2", "v2")
    ...
    .build();

• note that Guava's ImmutableMap implementation differs from Java's HashMap implementation (most notably it is immutable and does not permit null keys/values)
• for more info, see Guava's user guide article on its immutable collection types

Use a AJAX function which will call a php page synchronously and then in that page you can put the php usleep() function which will act as a delay.

function delay(t){

var xmlhttp;

if (window.XMLHttpRequest)

{// code for IE7+, Firefox, Chrome, Opera, Safari

xmlhttp=new XMLHttpRequest();

}

else

{// code for IE6, IE5

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xmlhttp.open("POST","http://www.hklabs.org/files/delay.php?time="+t,false);

//This will call the page named delay.php and the response will be sent to a division with ID as "response"

xmlhttp.send();

document.getElementById("response").innerHTML=xmlhttp.responseText;

}

If you want to plot a single line connecting all the points in the list

plt.plot(li[:])

plt.show()

This will plot a line connecting all the pairs in the list as points on a Cartesian plane from the starting of the list to the end. I hope that this is what you wanted.

Off the top of my head, here is a quick list, roughly sorted by frequency of use, of predefined attributes I actually use in a big project (~500k LoCs):

Flags, Serializable, WebMethod, COMVisible, TypeConverter, Conditional, ThreadStatic, Obsolete, InternalsVisibleTo, DebuggerStepThrough.

If you want to use global variable i of file1.c in file2.c, then below are the points to remember:

1. main function shouldn't be there in file2.c
2. now global variable i can be shared with file2.c by two ways:
   a) by declaring with extern keyword in file2.c i.e extern int i;
   b) by defining the variable i in a header file and including that header file in file2.c.

One very important thing to keep in mind when using a Regex based query - When you are doing this for a login system, escape every single character you are searching for, and don't forget the ^ and $ operators. Lodash has a nice function for this, should you be using it already:

db.stuff.find({$regex: new RegExp(_.escapeRegExp(bar), $options: 'i'})

Why? Imagine a user entering .* as his username. That would match all usernames, enabling a login by just guessing any user's password.

In C++11:

static const int a[] = {10, 20, 30};
vector<int> vec (begin(a), end(a));

Seems like database is not up. It might be due to restarting machine and the instance is not set to autostart and it so not started munually after starting from services Screen.

This is a good source for answering this question.

But this question is a kind of a always truth answere "Yes. Both."

It depends on your architecture. If you're going to work on a 16-bit machine or less, it can't be 4 byte (=32 bit). If you're working on a 32-bit or better machine, its length is 32-bit.

To figure out, get you program ready to output something readable and use the "sizeof" function. That returns the size in bytes of your declared datatype. But be carfull using this with arrays.

If you're declaring int t[12]; it will return 12*4 byte. To get the length of this array, just use sizeof(t)/sizeof(t[0]). If you are going to build up a function, that should calculate the size of a send array, remember that if

typedef int array[12];
int function(array t){
    int size_of_t = sizeof(t)/sizeof(t[0]);
    return size_of_t;
}
void main(){
    array t = {1,1,1};  //remember: t= [1,1,1,0,...,0]
    int a = function(t);    //remember: sending t is just a pointer and equal to int* t
   print(a);   // output will be 1, since t will be interpreted as an int itselve. 
}

So this won't even return something different. If you define an array and try to get the length afterwards, use sizeof. If you send an array to a function, remember the send value is just a pointer on the first element. But in case one, you always knows, what size your array has. Case two can be figured out by defining two functions and miss some performance. Define function(array t) and define function2(array t, int size_of_t). Call "function(t)" measure the length by some copy-work and send the result to function2, where you can do whatever you want on variable array-sizes.

I have faced this issue so many times and I was surprised that many of these don't work.

I simply deserialize the string with Newtonsoft.Json and I get cleartext.

string rough = "\"call 12\"";
rough = JsonConvert.DeserializeObject<string>(rough);

//the result is: "call 12";

You can check it from your command prompt by running gem help commands and then selecting the proper command:

Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.
kirti@kirti-Aspire-5733Z:~$ 

Now from the above I can see the command environment is helpful. So I would do:

kirti@kirti-Aspire-5733Z:~$ gem help environment
Usage: gem environment [arg] [options]


  Common Options:
    -h, --help                       Get help on this command
    -V, --[no-]verbose               Set the verbose level of output
    -q, --quiet                      Silence commands
        --config-file FILE           Use this config file instead of default
        --backtrace                  Show stack backtrace on errors
        --debug                      Turn on Ruby debugging


  Arguments:
    packageversion  display the package version
    gemdir          display the path where gems are installed
    gempath         display path used to search for gems
    version         display the gem format version
    remotesources   display the remote gem servers
    platform        display the supported gem platforms
    <omitted>       display everything

  Summary:
    Display information about the RubyGems environment

  Description:
    The RubyGems environment can be controlled through command line arguments,
    gemrc files, environment variables and built-in defaults.

    Command line argument defaults and some RubyGems defaults can be set in a
    ~/.gemrc file for individual users and a /etc/gemrc for all users. These
    files are YAML files with the following YAML keys:

      :sources: A YAML array of remote gem repositories to install gems from
      :verbose: Verbosity of the gem command. false, true, and :really are the
                levels
      :update_sources: Enable/disable automatic updating of repository metadata
      :backtrace: Print backtrace when RubyGems encounters an error
      :gempath: The paths in which to look for gems
      :disable_default_gem_server: Force specification of gem server host on
    push
      <gem_command>: A string containing arguments for the specified gem command

    Example:

      :verbose: false
      install: --no-wrappers
      update: --no-wrappers
      :disable_default_gem_server: true

    RubyGems' default local repository can be overridden with the GEM_PATH and
    GEM_HOME environment variables. GEM_HOME sets the default repository to
    install into. GEM_PATH allows multiple local repositories to be searched for
    gems.

    If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
    HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
    proxy server.

    If you would like to push gems to a private gem server the RUBYGEMS_HOST
    environment variable can be set to the URI for that server.

    If you are packaging RubyGems all of RubyGems' defaults are in
    lib/rubygems/defaults.rb.  You may override these in
    lib/rubygems/defaults/operating_system.rb
kirti@kirti-Aspire-5733Z:~$ 

Finally to show you what you asked, I would do:

kirti@kirti-Aspire-5733Z:~$ gem environment gemdir
/home/kirti/.rvm/gems/ruby-2.0.0-p0
kirti@kirti-Aspire-5733Z:~$ gem environment gempath
/home/kirti/.rvm/gems/ruby-2.0.0-p0:/home/kirti/.rvm/gems/ruby-2.0.0-p0@global
kirti@kirti-Aspire-5733Z:~$ 

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

As mentioned in other answers, there are multiple ways to generate a table of contents automatically. Most are open source software and can be adapted to your needs.

What I was missing is, however, a visually attractive formatting for a table of contents, using the limited options that Markdown provides. We came up with the following:

Code

## Content

**[1. Markdown](#heading--1)**

  * [1.1. Markdown formatting cheatsheet](#heading--1-1)
  * [1.2. Markdown formatting details](#heading--1-2)

**[2. BBCode formatting](#heading--2)**

  * [2.1. Basic text formatting](#heading--2-1)

      * [2.1.1. Not so basic text formatting](#heading--2-1-1)

  * [2.2. Lists, Images, Code](#heading--2-2)
  * [2.3. Special features](#heading--2-3)

----

Inside your document, you would place the target subpart markers like this:

<div id="heading--1-1"/>
### 1.1. Markdown formatting cheatsheet

Depending on where and how you use Markdown, the following should also work, and provides nicer-looking Markdown code:

### 1.1. Markdown formatting cheatsheet <a name="heading--1-1"/>

Example rendering

Content

1. Markdown

• 1.1. Markdown formatting cheatsheet
• 1.2. Markdown formatting details

2. BBCode formatting

• 2.1. Basic text formatting

  • 2.1.1. Not so basic text formatting

• 2.2. Lists, Images, Code

• 2.3. Special features

---

Advantages

• You can add as many levels of chapters and sub-chapters as you need. In the Table of Contents, these would appear as nested unordered lists on deeper levels.

• No use of ordered lists. These would create an indentation, would not link the number, and cannot be used to create decimal classification numbering like "1.1.".

• No use of lists for the first level. Here, using an unordered list is possible, but not necessary: the indentation and bullet just add visual clutter and no function here, so we don't use a list for the first ToC level at all.

• Visual emphasis on the first-level sections in the table of content by bold print.

• Short, meaningful subpart markers that look "beautiful" in the browser's URL bar such as #heading--1-1 rather than markers containing transformed pieces of the actual heading.

• The code uses H2 headings (## …) for sections, H3 headings (### …) for sub-headings etc.. This makes the source code easier to read because ## … provides a stronger visual clue when scrolling through compared to the case where sections would start with H1 headings (# …). It is still logically consistent as you use the H1 heading for the document title itself.

• Finally, we add a nice horizontal rule to separate the table of contents from the actual content.

For more about this technique and how we use it inside the forum software Discourse, see here.

For recent SQL:

select * from v$sql

For history:

select * from dba_hist_sqltext

I would suggest not to use list-style-image, as it behaves quite differently in different browsers, especially the image position

instead, you can use something like this

ol.widgets,
ol.widgets li { list-style: none; }
ol.widgets li { padding-left: 20px; backgroud: transparent ("image") no-repeat x y; }

it works in all browsers and would give you the identical result in different browsers.

Try this:

String hourMinute = DateTime.Now.ToString("HH:mm");

Now you will get the time in hour:minute format.

It worked: Project Properties -> ProjectFacets -> Runtimes -> jdk1.8.0_45 -> Apply

In case you also need to check if nextProps.blog is not undefined ; you can do that in a single if statement, like this:

if (typeof nextProps.blog !== "undefined" && typeof nextProps.blog.content !== "undefined") {
    //
}

And, when an undefined , empty or null value is not expected; you can make it more concise:

if (nextProps.blog && nextProps.blog.content) {
    //
}

You need to make sure the IIS Management Console is installed.

POP UP WINDOWS IN APPLET

hi guys i was searching pop up windows in applet all over the internet but could not find answer for windows.

Although it is simple i am just helping you. Hope you will like it as it is in simpliest form. here's the code :

Filename: PopUpWindow.java for java file and we need html file too.

For applet let us take its popup.html

CODE:

import java.awt.*;

import java.applet.*;

import java.awt.event.*;

public class PopUpWindow extends Applet{

public void init(){

Button open = new Button("open window");

add(open);

Button close = new Button("close window");

add(close);

 Frame f = new Frame("pupup win");

  f.setSize(200,200);




 open.addActionListener(new ActionListener() {

                 public void actionPerformed(ActionEvent e) {
                     if(!f.isShowing()) {
                         f.setVisible(true);
                     }


                 }

              });
 close.addActionListener(new ActionListener() {

                 public void actionPerformed(ActionEvent e) {
                     if(f.isShowing()) {
                        f.setVisible(false);
                     }

                 }

              });

 }

}




/*
<html>

<body>

<APPLET CODE="PopUpWindow" width="" height="">

</APPLET>

</body>

</html>

*/


to run:
$javac PopUpWindow.java && appletviewer popup.html

if none of the above solutions worked for you.

in my case phpmyadmin was using a deferent configuration file(php.ini). to know what config file used by phpmyadmin :

go /usr/share/phpmyadmin then edit index.php file and make it start with this

<?php
phpinfo();
die();
// ...

now when you visit localhost/phpmyadmin you can search for php.ini.

you can tell where the config file is , in my case it was /etc/php/7.3/apache2/php.ini

now you need to update upload_max_filesize and post_max_size and you may need to change upload_tmp_dir

save your changes and then run sudo service apache2 restart

now everything should be OK

You could tell wget to not download the contents in a couple of different ways:

wget --spider http://www.example.com/cronit.php

which will just perform a HEAD request but probably do what you want

wget -O /dev/null http://www.example.com/cronit.php

which will save the output to /dev/null (a black hole)

You might want to look at wget's -q switch too which prevents it from creating output

I think that the best option would probably be:

wget -q --spider http://www.example.com/cronit.php

that's unless you have some special logic checking the HTTP method used to request the page

}

For example:

you can use:

df %>% filter(!is.na(a))

to remove the NA in column a.

Here's a general example with obvious delimiters (X and Y):

(?<=X)(.*?)(?=Y)

Here it's used to find the string between X and Y. Rubular example here, or see image:

Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).

It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).

But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.

A good example: here

And a good documentation from Mozilla: here

Consider the code below:

public class X
{
    public void methodA() // Base class method
    {
        System.out.println ("hello, I'm methodA of class X");
    }
}

public class Y extends X
{
    public void methodA() // Derived Class method
    {
        System.out.println ("hello, I'm methodA of class Y");
    }
}
public class Z
{
public static void main (String args []) {

    //this takes input from the user during runtime
    System.out.println("Enter x or y");
    Scanner scanner = new Scanner(System.in);
    String value= scanner.nextLine();

    X obj1 = null;
    if(value.equals("x"))
        obj1 = new X(); // Reference and object X
    else if(value.equals("y"))
        obj2 = new Y(); // X reference but Y object
    else
        System.out.println("Invalid param value");

    obj1.methodA();
}
}

Now, looking at the code you can never tell which implementation of methodA() will be executed, Because it depends on what value the user gives during runtime. So, it is only decided during the runtime as to which method will be called. Hence, Runtime polymorphism.

Another way to generate the serialVersionUID is to use >Analyze >Run Inspection by Name from the context menu ( or the keyboard short cut, which is ctrl+alt+shift+i by default) and then type "Serializable class without 'serialVersionUID'" (or simply type "serialVersionUID" and the type ahead function will find it for you.

You will then get a context menu where you can choose where to run the inspections on (e.g. all from a specific module, whole project, one file, ...)

With this approach you don't even have to set the general inspection rules to anything.

As was previously answered, you can cast back and forth between signed and unsigned without a problem. The border case for signed integers is -1 (0xFFFFFFFF). Try adding and subtracting from that and you'll find that you can cast back and have it be correct.

However, if you are going to be casting back and forth, I would strongly advise naming your variables such that it is clear what type they are, eg:

int iValue, iResult;
unsigned int uValue, uResult;

It is far too easy to get distracted by more important issues and forget which variable is what type if they are named without a hint. You don't want to cast to an unsigned and then use that as an array index.

I just did it the old way i know that its not right but its a quick fix.

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

Note that if you're using Sublime as your commit editor, you need the -n -w flags, otherwise git keeps thinking your commit message is empty and aborting.

Even if the test gurus say that we should not do it: I do. In some context it makes a lot of sense to have parameters to drive the test in the right direction, for example:

• which of the dozen identical USB cards should I use for this test now?
• which server should I use for this test now?
• which XXX should I use?

For me, the use of the environment variable is good enough for this puprose because you do not have to write dedicated code to pass your parameters around; it is supported by Python. It is clean and simple.

Of course, I'm not advocating for fully parametrizable tests. But we have to be pragmatic and, as I said, in some context you need a parameter or two. We should not abouse of it :)

import os
import unittest


class MyTest(unittest.TestCase):
    def setUp(self):
        self.var1 = os.environ["VAR1"]
        self.var2 = os.environ["VAR2"]

    def test_01(self):
        print("var1: {}, var2: {}".format(self.var1, self.var2))

Then from the command line (tested on Linux)

$ export VAR1=1
$ export VAR2=2
$ python -m unittest MyTest
var1: 1, var2: 2
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK

And finally, without using floating point hacks:

function genpasswd(n) {
    // 36 ** 11 > Number.MAX_SAFE_INTEGER
    if (n > 10)
        throw new Error('Too big n for this function');
    var x = "0000000000" + Math.floor(Number.MAX_SAFE_INTEGER * Math.random()).toString(36);
    return x.slice(-n);
}

In general, you either have to specify $(OBJDIR) on the left hand side of all the rules that place files in $(OBJDIR), or you can run make from $(OBJDIR). VPATH is for sources, not for objects.

Take a look at these two links for more explanation, and a "clever" workaround.

Difference between Paint() and Repaint() method

Paint():

This method holds instructions to paint this component. Actually, in Swing, you should change paintComponent() instead of paint(), as paint calls paintBorder(), paintComponent() and paintChildren(). You shouldn't call this method directly, you should call repaint() instead.

Repaint():

This method can't be overridden. It controls the update() -> paint() cycle. You should call this method to get a component to repaint itself. If you have done anything to change the look of the component, but not its size ( like changing color, animating, etc. ) then call this method.

Unit Testing - As the name suggests, this method tests at the object level. Individual software components are tested for any errors. Knowledge of the program is needed for this test and the test codes are created to check if the software behaves as it is intended to.

Functional Testing - Is carried out without any knowledge of the internal working of the system. The tester will try to use the system by just following requirements, by providing different inputs and testing the generated outputs. This test is also known as closed-box testing or black-box.

Acceptance Testing - This is the last test that is conducted before the software is handed over to the client. It is carried out to ensure that the developed software meets all the customer requirements. There are two types of acceptance testing - one that is carried out by the members of the development team, known as internal acceptance testing (Alpha testing), and the other that is carried out by the customer or end user known as (Beta testing)

Integration Testing - Individual modules that are already subjected to unit testing are integrated with one another. Generally the two approachs are followed :

1) Top-Down
2) Bottom-Up

You DO NOT have to provide a body for getters and setters IF you'd like the automated compiler to provide a basic implementation.

This DOES however require you to make sure you're using the v3.5 compiler by updating your web.config to something like

 <compilers>
   <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
    <providerOption name="CompilerVersion" value="v3.5"/>
    <providerOption name="WarnAsError" value="false"/>
  </compiler>
</compilers>

To install 32-bit Java on Windows 7 (64-bit OS + Machine). You can do:

1) Download JDK: http://javadl.sun.com/webapps/download/AutoDL?BundleId=58124
2) Download JRE: http://www.java.com/en/download/installed.jsp?jre_version=1.6.0_22&vendor=Sun+Microsystems+Inc.&os=Linux&os_version=2.6.41.4-1.fc15.i686

3) System variable create: C:\program files (x86)\java\jre6\bin\

4) Anywhere you type java -version

it use 32-bit on (64-bit). I have to use this because lots of third party libraries do not work with 64-bit. Java wake up from the hell, give us peach :P. Go-language is killer.

To align horizontally it's pretty straight forward:

    <style type="text/css"> 
body  {
    margin: 0; 
    padding: 0;
    text-align: center;
}
.bodyclass #container { 
    width: ???px; /*SET your width here*/
    margin: 0 auto;
    text-align: left;
} 
</style>
<body class="bodyclass ">
<div id="container">type your content here</div>
</body>

and for vertical align, it's a bit tricky: here's the source

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
  <title>Universal vertical center with CSS</title>
  <style>
    .greenBorder {border: 1px solid green;} /* just borders to see it */
  </style>
</head>

<body>
  <div class="greenBorder" style="display: table; height: 400px; #position: relative; overflow: hidden;">
    <div style=" #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
      <div class="greenBorder" style=" #position: relative; #top: -50%">
        any text<br>
        any height<br>
        any content, for example generated from DB<br>
        everything is vertically centered
      </div>
    </div>
  </div>
</body>
</html>

Solution utilizing JS Map:

const merge = (arr1, arr2, prop) => {
    const resultMap = new Map(arr1.map((item) => [item[prop], item]));
    arr2.forEach((item) => {
        const mapItem = resultMap.get(item[prop]);
        if (mapItem) Object.assign(mapItem, item);
        else resultMap.set(item[prop], item);
    });
    return [...resultMap.values()];
};

const arr1 = new Array({name: "lang", value: "English"}, {name: "age", value: "18"});
const arr2 = new Array({name : "childs", value: '5'}, {name: "lang", value: "German"});

console.log(merge(arr1, arr2, "name"));

Which produces:

In View the code is:

<script language="javascript" type="text/javascript">
    function SubmeterForm(id)
    {
        if (id=='btnOk')
            document.forms[0].submit(id);
        else
            document.forms[1].submit(id);
    }
</script>


<% Html.BeginForm("ObterNomeBotaoClicado/1", "Teste01", FormMethod.Post); %>
<input id="btnOk" type="button" value="Ok" onclick="javascript:SubmeterForm('btnOk')" />
<% Html.EndForm(); %>
<% Html.BeginForm("ObterNomeBotaoClicado/2", "Teste01", FormMethod.Post); %>
<input id="btnCancelar" type="button" value="Cancelar" onclick="javascript:SubmeterForm('btnCancelar')" />
<% Html.EndForm(); %>

In Controller the code is:

public ActionResult ObterNomeBotaoClicado(string id)
{
    if (id=="1")
        btnOkFunction(...);
    else
        btnCancelarFunction(...);
    return View();
}

There are many other binaries that need to be linked so I think it's much better to try something like sudo update-alternatives --all and choosing the right alternatives for everything else besides java and javac.

Try to use toISOString(). It returns string in ISO8601 format.

GET method

javascript

$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
    console.log(result);
});

c#

[HttpGet]
public JsonResult DoGet(DateTime date)
{
    return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}

POST method

javascript

$.post('/example/do', { date: date.toISOString() }, function (result) {
    console.log(result);
});

c#

[HttpPost]
public JsonResult Do(DateTime date)
{
     return Json(date.ToString());
}

A related question has been asked before: What is “above-the-fold content” in Google Pagespeed?

Firstly you have to notice that this is all about 'mobile pages'.
So when I interpreted your question and screenshot correctly, then this is not for your site!

On the contrary - doing some of the things advised by Google in their guidelines will things make worse than better for 'normal' websites.
And not everything that comes from Google is the "holy grail" just because it comes from Google. And they themselves are not a good role model if you have a look at their HTML markup.

The best advice I could give you is:

• Set width and height on replaced elements in your CSS, so that the browser can layout the elements and doesn't have to wait for the replaced content!

Additionally why do you use different CSS files, rather than just one?
The additional request is worse than the small amount of data volume. And after the first request the CSS file is cached anyway.

The things one should always take care of are:

• reduce the number of requests as much as possible
• keep your overall page weight as low as possible

And don't puzzle your brain about how to get 100% of Google's PageSpeed Insights tool ...! ;-)

Addition 1: Here is the page on which Google shows us, what they recommend for Optimize CSS Delivery.

As said before, I don't think that this is neither realistic nor that it makes sense for a "normal" website! Because mainly when you have a responsive web design it is most certain that you use media queries and other layout styles. So if you are not gonna load your CSS first and in a blocking manner you'll get a FOUT (Flash Of Unstyled Text). I really do not believe that this is "better" than at least some more milliseconds to render the page!

Imho Google is starting a new "hype" (when I have a look at all the question about it here on Stackoverflow) ...!

It appears to only be availabe using the mysqlnd driver.
Try replacing it with the integer it represents; 1002, if I am not mistaken.

Basically @classmethod makes a method whose first argument is the class it's called from (rather than the class instance), @staticmethod does not have any implicit arguments.

Assuming the original date is in cell A1:

=DATE(YEAR(A1), MONTH(A1), DAY(A1)-180)

If you want the ASCII value of all the characters in a String. You can use this :

String a ="asdasd";
int count =0;
for(int i : a.toCharArray())
    count+=i;

and if you want ASCII of a single character in a String you can go for :

(int)a.charAt(index);

I stumbled on an article and this worked best for me

1. Open up the config.inc.php file within the phpmyadmin dir with your favorite code editor. In your local MAMP environment, it should be located here:

Hard Drive » Applications » MAMP » bin » config.inc.php

2. Do a search for the phrase $cfg[‘UploadDir’] – it’s going to look like this:

$cfg['UploadDir'] = '';

3. Change it to look like this:

$cfg['UploadDir'] = 'upload';

4. Then, within that phpmyadmin dir, create a new folder & name it upload.

5. Take that large .sql file that you’re trying to import, and put it in that new upload folder.

6. Now, the next time you go to import a database into phpMyAdmin, you’ll see a new dropdown field right below the standard browse area in your “File to Import” section.

For Android 7, Galaxy S6 Edge:

1. Settings > Developer Options > Turn the switch ON > Debugging Mode (Turn On)

If Developer Options is not available then

2. Settings > About Device > Software Info > Build number (Tap It 7 time)

Now perform step 1. Now it should work, if its still not working then perform these steps. It worked for me.

Datepicker in german (Deutsch):

$.datepicker.regional['de'] = {
    monthNames: ['Januar','Februar','März','April','Mai','Juni',
    'Juli','August','September','Oktober','November','Dezember'],
    monthNamesShort: ['Jan','Feb','Mär','Apr','Mai','Jun',
    'Jul','Aug','Sep','Okt','Nov','Dez'],
    dayNames: ['Sonntag','Montag','Dienstag','Mittwoch','Donnerstag','Freitag','Samstag'],
    dayNamesShort: ['Son','Mon','Die','Mit','Don','Fre','Sam'],
    dayNamesMin: ['So','Mo','Di','Mi','Do','Fr','Sa'],
    firstDay: 1};
 $.datepicker.setDefaults($.datepicker.regional['de']);

For me git add -p is the most useful way (and intended I think by git developers?) to review all unstaged changes (it shows the diff for each file), choose a good set of changes that ought to go with a commit, then when you have staged all of those, then use git commit, and repeat for the next commit. Then you can make each commit be a useful or meaningful set of changes even if they took place in various files. I would also suggest creating a new branch for each ticket or similar activity, and switch between them using checkout (perhaps using git stash if you don't want to commit before switching), though if you are doing many quick changes this may be a pain. Don't forget to merge often.

You could use the window size and hard code the breakpoints. Using Angular:

angular
    .module('components.responsiveDetection', [])
    .factory('ResponsiveDetection', function ($window) {
        return {
            getBreakpoint: function () {
                var w = $window.innerWidth;
                if (w < 768) {
                    return 'xs';
                } else if (w < 992) {
                    return 'sm';
                } else if (w < 1200) {
                    return 'md';
                } else {
                    return 'lg';
                }
            }
        };
    });

Your code has lots of errors.

• You are mixing up dm$Day and dm$day. Probably not the same thing
• Your column headings are Date and Visits. So you would access them (I'm guessing) as dm$Date and dm$Visits
• In the date field you have %Y-%m-%d this should be %m/%d/%Y

The following code should plot what you want:

dm$newday = as.Date(dm$Date, "%m/%d/%Y")
plot(dm$newday, dm$Visits)

This looks like a problem with line endings in your code. If you're going to be using all these other scientific packages, you may as well use Pandas for the CSV reading part, which is both more robust and more useful than just the csv module:

import pandas
colnames = ['year', 'name', 'city', 'latitude', 'longitude']
data = pandas.read_csv('test.csv', names=colnames)

If you want your lists as in the question, you can now do:

names = data.name.tolist()
latitude = data.latitude.tolist()
longitude = data.longitude.tolist()

A quick way to execute some time-consuming operation in any constructor is by creating an action and run them asynchronously.

new Action( async() => await InitializeThingsAsync())();

Running this piece of code will neither block your UI nor leave you with any loose threads. And if you need to update any UI (considering you are not using MVVM approach), you can use the Dispatcher to do so as many have suggested.

A Note: This option only provides you a way to start an execution of a method from the constructor if you don't have any init or onload or navigated overrides. Most likely this will keep on running even after the construction has been completed. Hence the result of this method call may NOT be available in the constructor itself.

I just wrote this for another question, then stumbled here.

library(lubridate)

#' Calculate age
#' 
#' By default, calculates the typical "age in years", with a
#' \code{floor} applied so that you are, e.g., 5 years old from
#' 5th birthday through the day before your 6th birthday. Set
#' \code{floor = FALSE} to return decimal ages, and change \code{units}
#' for units other than years.
#' @param dob date-of-birth, the day to start calculating age.
#' @param age.day the date on which age is to be calculated.
#' @param units unit to measure age in. Defaults to \code{"years"}. Passed to \link{\code{duration}}.
#' @param floor boolean for whether or not to floor the result. Defaults to \code{TRUE}.
#' @return Age in \code{units}. Will be an integer if \code{floor = TRUE}.
#' @examples
#' my.dob <- as.Date('1983-10-20')
#' age(my.dob)
#' age(my.dob, units = "minutes")
#' age(my.dob, floor = FALSE)
age <- function(dob, age.day = today(), units = "years", floor = TRUE) {

age(seq(my.dob, length.out = 6, by = "years"))
# [1] 31 30 29 28 27 26

That error is due to missing of modules in pyinstaller. You can find the missing modules by running script in executable command line, i.e., by removing '-w' from the command. Once you created the command line executable file then in command line it will show the missing modules. By finding those missing modules you can add this to your command : " --hidden-import = missingmodule "

I solved my problem through this.

I believe that using "cbind" is the simplest way to add a column to a data frame in R. Below an example:

    myDf = data.frame(index=seq(1,10,1), Val=seq(1,10,1))
    newCol= seq(2,20,2)
    myDf = cbind(myDf,newCol)

Use:

Target= "_blank" property of anchor tag

For dynamic SQL use:

'IN(' ||array_to_string(some_array, ',')||')'

Example

DO LANGUAGE PLPGSQL $$

DECLARE
    some_array bigint[];
    sql_statement text;

BEGIN

    SELECT array[1, 2] INTO some_array;
    RAISE NOTICE '%', some_array;

    sql_statement := 'SELECT * FROM my_table WHERE my_column IN(' ||array_to_string(some_array, ',')||')';
    RAISE NOTICE '%', sql_statement;

END;

$$;

Result: NOTICE: {1,2} NOTICE: SELECT * FROM my_table WHERE my_column IN(1,2)

A Bcrypt hash can be stored in a BINARY(40) column.

BINARY(60), as the other answers suggest, is the easiest and most natural choice, but if you want to maximize storage efficiency, you can save 20 bytes by losslessly deconstructing the hash. I've documented this more thoroughly on GitHub: https://github.com/ademarre/binary-mcf

Bcrypt hashes follow a structure referred to as modular crypt format (MCF). Binary MCF (BMCF) decodes these textual hash representations to a more compact binary structure. In the case of Bcrypt, the resulting binary hash is 40 bytes.

Gumbo did a nice job of explaining the four components of a Bcrypt MCF hash:

$<id>$<cost>$<salt><digest>

Decoding to BMCF goes like this:

1. $<id>$ can be represented in 3 bits.
2. <cost>$, 04-31, can be represented in 5 bits. Put these together for 1 byte.
3. The 22-character salt is a (non-standard) base-64 representation of 128 bits. Base-64 decoding yields 16 bytes.
4. The 31-character hash digest can be base-64 decoded to 23 bytes.
5. Put it all together for 40 bytes: 1 + 16 + 23

You can read more at the link above, or examine my PHP implementation, also on GitHub.

It's really a matter of opinion. In your example, System.out.println(5) would be slightly more efficient, as you only refer to the number once and never change it. As was said in a comment, int is a primitive type and not a reference - thus it doesn't take up much space. However, you might want to set actual reference variables to null only if they are used in a very complicated method. All local reference variables are garbage collected when the method they are declared in returns.

As other have mentioned you can't display an image in an alert. The solution is to show it on the webpage.

If I have my webpage paused in the debugger and I already have an image loaded, I can display it. There is no need to use jQuery; with this native 14 lines of Javascript it will work from code or the debugger command line:

function show(img){
 var _=document.getElementById('_'); 
 if(!_){_=document.createElement('canvas');document.body.appendChild(_);}
 _.id='_';
 _.style.top=0;
 _.style.left=0;
 _.width=img.width;
 _.height=img.height;
 _.style.zIndex=9999; 
 _.style.position='absolute';
 _.getContext('2d').drawImage(img,0,0);
}

Usage:

show( myimage );

Tried @hellslam's and @silverfighter's answers. I found a race condition holding my tests back. In my case I'm running mocha tests and in the before function of the test I want to erase the entire DB. Here's what works for me.

var con = mongoose.connect('mongodb://localhost/mydatabase');
mongoose.connection.on('open', function(){
    con.connection.db.dropDatabase(function(err, result){
        done();
    });
});

Java 8 implementation (List initialized with 60 zeroes):

List<Integer> list = IntStream.of(new int[60])
                    .boxed()
                    .collect(Collectors.toList());

• new int[N] - creates an array filled with zeroes & length N
• boxed() - each element boxed to an Integer
• collect(Collectors.toList()) - collects elements of stream

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

Whatever your separator is in your ls.dat, you can specify it to gnuplot:

set datafile separator "\t"

There's also the pygame.freetype module which is more modern, works with more fonts and offers additional functionality.

Create a font object with pygame.freetype.SysFont() or pygame.freetype.Font if the font is inside of your game directory.

You can render the text either with the render method similarly to the old pygame.font.Font.render or directly onto the target surface with render_to.

import pygame
import pygame.freetype  # Import the freetype module.


pygame.init()
screen = pygame.display.set_mode((800, 600))
GAME_FONT = pygame.freetype.Font("your_font.ttf", 24)
running =  True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.fill((255,255,255))
    # You can use `render` and then blit the text surface ...
    text_surface, rect = GAME_FONT.render("Hello World!", (0, 0, 0))
    screen.blit(text_surface, (40, 250))
    # or just `render_to` the target surface.
    GAME_FONT.render_to(screen, (40, 350), "Hello World!", (0, 0, 0))

    pygame.display.flip()

pygame.quit()

python install it by default but if not install you can install it manual use following cmd (for linux only )

for python3 :

sudo apt install python3-pip 

for python2

sudo apt install python-pip 

hope its help.

Here is a different approach using mix-blend-mode: difference, that will actually invert whatever the background is, not just a single colour:

div {_x000D_
  background-image: linear-gradient(to right, red, yellow, green, cyan, blue, violet);_x000D_
}_x000D_
p {_x000D_
  color: white;_x000D_
  mix-blend-mode: difference;_x000D_
}

<div>_x000D_
  <p>Lorem ipsum dolor sit amet, consectetur adipiscit elit, sed do</p>_x000D_
</div>

I suggest you take a look at the code on kevinsawicki/http-request, its basically a wrapper on top of HttpUrlConnection it provides a much simpler API in case you just want to make the requests right now or you can take a look at the sources (it's not too big) to take a look at how connections are handled.

Example: Make a GET request with content type application/json and some query parameters:

// GET http://google.com?q=baseball%20gloves&size=100
String response = HttpRequest.get("http://google.com", true, "q", "baseball gloves", "size", 100)
        .accept("application/json")
        .body();
System.out.println("Response was: " + response);

You should start with the Wikipedia Filename page. It has a decent-sized table (Comparison of filename limitations), listing the reserved characters for quite a lot of file systems.

It also has a plethora of other information about each file system, including reserved file names such as CON under MS-DOS. I mention that only because I was bitten by that once when I shortened an include file from const.h to con.h and spent half an hour figuring out why the compiler hung.

Turns out DOS ignored extensions for devices so that con.h was exactly the same as con, the input console (meaning, of course, the compiler was waiting for me to type in the header file before it would continue).

you didn't complete your try statement. You need and except in there too.

JOIN t2 ON (t2.id = t1.id AND t2.date = t1.date)

var a = 5.467;
var truncated = Math.floor(a * 100) / 100; // = 5.46

This problem can be solved efficiently using the numpy_indexed library (disclaimer: I am its author); which was created to address problems of this type. npi.indices can be viewed as an n-dimensional generalisation of list.index. It will act on nd-arrays (along a specified axis); and also will look up multiple entries in a vectorized manner as opposed to a single item at a time.

a = np.random.rand(50, 60, 70)
i = np.random.randint(0, len(a), 40)
b = a[i]

import numpy_indexed as npi
assert all(i == npi.indices(a, b))

This solution has better time complexity (n log n at worst) than any of the previously posted answers, and is fully vectorized.

Since you are going to use this in a login page. Here is a code I used in a Login page using Material-UI

<Grid
  container
  spacing={0}
  direction="column"
  alignItems="center"
  justify="center"
  style={{ minHeight: '100vh' }}
>

  <Grid item xs={3}>
    <LoginForm />
  </Grid>   

</Grid> 

this will make this login form at the center of the screen.

But still IE doesn't support the Material-UI Grid and you will see some misplaced content in IE.

Hope this will help you.

For some reason I could not get this to work with the proposed answers, but I found another variation, using select, that worked for me:

models.Post.find().sort('-date').limit(10).select('published').exec(function(e, data){
        ...
});

Has the api perhaps changed? I am using version 3.8.19

To fetch column name, instead of using readlines() better use readline() to avoid loop & reading the complete file & storing it in the array.

with open(csv_file, 'rb') as csvfile:

    # get number of columns

    line = csvfile.readline()

    first_item = line.split(',')

Is it possible that the date could actually be outside that range? Does it come from user input? If the answer to either of these questions is yes, then you should always check - otherwise you're leaving your application prone to error.

You can format your date for inclusion in an SQL statement rather easily:

var sqlFormattedDate = myDateTime.Date.ToString("yyyy-MM-dd HH:mm:ss");

you can calculate it as :

import math
def sigmoid(x):
  return 1 / (1 + math.exp(-x))

or conceptual, deeper and without any imports:

def sigmoid(x):
  return 1 / (1 + 2.718281828 ** -x)

or you can use numpy for matrices:

import numpy as np #make sure numpy is already installed
def sigmoid(x):
  return 1 / (1 + np.exp(-x))

This is basically Muhammad Saqib's answer except two diffs:

1: Adds width and height function parameters.

2: This is a small nuance which can be ignored... Saying 'As Bitmap', instead of 'As Image'. 'As Image' does work just fine. I just prefer to match Return types. See Image VS Bitmap Class.

Public Shared Function ResizeImage(ByVal InputBitmap As Bitmap, width As Integer, height As Integer) As Bitmap
    Return New Bitmap(InputImage, New Size(width, height))
End Function

Ex.

Dim someimage As New Bitmap("C:\somefile")
someimage = ResizeImage(someimage,800,600)

You can bootstrap. Now a days, almost all websites are developed using bootstrap. You can simply add bootstrap link in head of html file. Now simply add class="btn btn-primary" and your button will look like a normal button. Even you can use btn class on a tag as well, it will look like button on UI.

You can have only one public class in a file else you will get the error what you are getting now and name of file must be the name of public class

I am not sure what you understand by "execute from the Command line interface", but you're probably looking after the following select statement:

select * from dba_users;

or

select username from dba_users;

this worked for me..

 function getScrollbarWidth() { 
    var div = $('<div style="width:50px;height:50px;overflow:hidden;position:absolute;top:-200px;left:-200px;"><div style="height:100px;"></div>'); 
    $('body').append(div); 
    var w1 = $('div', div).innerWidth(); 
    div.css('overflow-y', 'scroll'); 
    var w2 = $('div', div).innerWidth(); 
    $(div).remove(); 
    return (w1 - w2); 
}

Although this is somewhat old I would like to add a slightly improved version that really changes column order. Here are the steps (assuming we have a table TAB1 with columns COL1, COL2, COL3):

1. Add new column to table TAB1:

alter table TAB1 add (NEW_COL number);

1. "Copy" table to temp name while changing the column order AND rename the new column:

create table tempTAB1 as select NEW_COL as COL0, COL1, COL2, COL3 from TAB1;

1. drop existing table:

drop table TAB1;

1. rename temp tablename to just dropped tablename:

rename tempTAB1 to TAB1;

LibHaru

Haru is a free, cross platform, open-sourced software library for generating PDF written in ANSI-C. It can work as both a static-library (.a, .lib) and a shared-library (.so, .dll).

Didn't try it myself, but maybe it can help you

I'm not sure if this is a good solution but it removed the error. I commented out the line:

from numpy._distributor_init import NUMPY_MKL 

and it worked. Not sure if this will cause other features to break though

The maven dependency plugin can potentially solve your problem.

If you have a pom with all your project dependencies specified, all you would need to do is run

mvn dependency:copy-dependencies

and you will find the target/dependencies folder filled with all the dependencies, including transitive.

Adding Gustavo's answer from below: To download the dependency sources, you can use

mvn dependency:copy-dependencies -Dclassifier=sources

(via Apache Maven Dependency Plugin doc).
