Here is a function to compute the weighted r-squared with Python and Numpy (most of the code comes from sklearn):

from __future__ import division 
import numpy as np

def compute_r2_weighted(y_true, y_pred, weight):
    sse = (weight * (y_true - y_pred) ** 2).sum(axis=0, dtype=np.float64)
    tse = (weight * (y_true - np.average(
        y_true, axis=0, weights=weight)) ** 2).sum(axis=0, dtype=np.float64)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse

Example:

from __future__ import print_function, division 
import sklearn.metrics 

def compute_r2_weighted(y_true, y_pred, weight):
    sse = (weight * (y_true - y_pred) ** 2).sum(axis=0, dtype=np.float64)
    tse = (weight * (y_true - np.average(
        y_true, axis=0, weights=weight)) ** 2).sum(axis=0, dtype=np.float64)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse    

def compute_r2(y_true, y_predicted):
    sse = sum((y_true - y_predicted)**2)
    tse = (len(y_true) - 1) * np.var(y_true, ddof=1)
    r2_score = 1 - (sse / tse)
    return r2_score, sse, tse

def main():
    '''
    Demonstrate the use of compute_r2_weighted() and checks the results against sklearn
    '''        
    y_true = [3, -0.5, 2, 7]
    y_pred = [2.5, 0.0, 2, 8]
    weight = [1, 5, 1, 2]
    r2_score = sklearn.metrics.r2_score(y_true, y_pred)
    print('r2_score: {0}'.format(r2_score))  
    r2_score,_,_ = compute_r2(np.array(y_true), np.array(y_pred))
    print('r2_score: {0}'.format(r2_score))
    r2_score = sklearn.metrics.r2_score(y_true, y_pred,weight)
    print('r2_score weighted: {0}'.format(r2_score))
    r2_score,_,_ = compute_r2_weighted(np.array(y_true), np.array(y_pred), np.array(weight))
    print('r2_score weighted: {0}'.format(r2_score))

if __name__ == "__main__":
    main()
    #cProfile.run('main()') # if you want to do some profiling

outputs:

r2_score: 0.9486081370449679
r2_score: 0.9486081370449679
r2_score weighted: 0.9573170731707317
r2_score weighted: 0.9573170731707317

This corresponds to the formula (mirror):

with f_i is the predicted value from the fit, y_{av} is the mean of the observed data y_i is the observed data value. w_i is the weighting applied to each data point, usually w_i=1. SSE is the sum of squares due to error and SST is the total sum of squares.

The str.split method will automatically remove all white space between items:

>>> str1 = "a    b     c      d"
>>> str1.split()
['a', 'b', 'c', 'd']

Most of the answers seem to be for svn+ssh, or don't seem to work for us.

For http access, the easiest way to log out an SVN user from the command line is:

rm ~/.subversion/auth/svn.simple/*

Hat tip: http://www.yolinux.com/TUTORIALS/Subversion.html

For Swift 3 it's:

label.textAlignment = .center

If you're finding by Contains then it'll be like this

    $("input[id*='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Starts With then it'll be like this

    $("input[id^='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Ends With then it'll be like this

     $("input[id$='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is not a given string

    $("input[id!='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which name contains a given word, delimited by spaces

     $("input[name~='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is equal to a given string or starting with that string followed by a hyphen

     $("input[id|='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

There are several possibilities:

1. You're facing a server problem. The server does not have any mail server. So your mail is not working, because your code is fine and mail is working with type.

2. You are not getting the posted value. Try your code with a static value.

3. Use SMTP mails to send mail...

If you're using some plugin which takes string and use construct Regex to create Regex Object i:e new RegExp()

Than Below string will work

'^\\S*$'

It's same regex @Bergi mentioned just the string version for new RegExp constructor

Mostly this is caused with an issue in your React/Client app. Adding this line to your client package.json solves it

"proxy": "http://localhost:5000/"

Note: Replace 5000, with the port number where your server is running

If you are using jQuery then:

HTML:

 <a id="openMap" href="/map/">link</a>

JS:

$(document).ready(function() {
    $("#openMap").click(function(){
        popup('/map/', 300, 300, 'map');
        return false;
    });
});

This has the benefit of still working without JS, or if the user middle clicks the link.

It also means that I could handle generic popups by rewriting again to:

HTML:

 <a class="popup" href="/map/">link</a>

JS:

$(document).ready(function() {
    $(".popup").click(function(){
        popup($(this).attr("href"), 300, 300, 'map');
        return false;
    });
});

This would let you add a popup to any link by just giving it the popup class.

This idea could be extended even further like so:

HTML:

 <a class="popup" data-width="300" data-height="300" href="/map/">link</a>

JS:

$(document).ready(function() {
    $(".popup").click(function(){
        popup($(this).attr("href"), $(this).data('width'), $(this).data('height'), 'map');
        return false;
    });
});

I can now use the same bit of code for lots of popups on my whole site without having to write loads of onclick stuff! Yay for reusability!

It also means that if later on I decide that popups are bad practice, (which they are!) and that I want to replace them with a lightbox style modal window, I can change:

popup($(this).attr("href"), $(this).data('width'), $(this).data('height'), 'map');

to

myAmazingModalWindow($(this).attr("href"), $(this).data('width'), $(this).data('height'), 'map');

and all my popups on my whole site are now working totally differently. I could even do feature detection to decide what to do on a popup, or store a users preference to allow them or not. With the inline onclick, this requires a huge copy and pasting effort.

Late but document fragment could be a node:

function hasChild(el){
    var child = el && el.firstChild;
    while (child) {
        if (child.nodeType === 1 || child.nodeType === 11) {
            return true;
        }
        child = child.nextSibling;
    }
    return false;
}
// or
function hasChild(el){
    for (var i = 0; el && el.childNodes[i]; i++) {
        if (el.childNodes[i].nodeType === 1 || el.childNodes[i].nodeType === 11) {
            return true;
        }
    }
    return false;
}

The below code solves two problems: 1) dynamically set the selected value of the dropdownlist and 2) more importantly to create a dropdownlistfor for an indexed array in the model. the problem here is that everyone uses one instance of the selectlist which is the ViewBoag.List, while the array needs one Selectlist instance for each dropdownlistfor to be able to set the selected value.

create the ViewBag variable as List (not SelectList) int he controller

//controller code
ViewBag.Role = db.LUT_Role.ToList();

//in the view @Html.DropDownListFor(m => m.Contacts[i].Role, new SelectList(ViewBag.Role,"ID","Role",Model.Contacts[i].Role))

Visual Studio 2015 does include Xamarin Starter edition https://xamarin.com/starter

Xamarin Starter is free and allows developers to build and publish simple apps with the following limitations:

• Contain no more than 128k of compiled user code (IL)
• Do NOT call out to native third party libraries (i.e., developers may not P/Invoke into C/C++/Objective-C/Java)
• Built using Xamarin.iOS / Xamarin.Android (NOT Xamarin.Forms)

Xamarin Starter installs automatically with Visual Studio 2015, and works with VS 2012, 2013, and 2015 (including Community Editions). When your app outgrows Starter, you will be offered the opportunity to upgrade to a paid subscription, which you can learn more about here: https://store.xamarin.com/

This error can happen because some MFC library (eg. mfc120.dll) from which the DLL is dependent is missing in windows/system32 folder.

Reduce() is..

• The reduce() method reduces the array to a single value.
• The reduce() method executes a provided function for each value of the array (from left-to-right).
• The return value of the function is stored in an accumulator (result/total).

It was ..

let array=[1,2,3];
function sum(acc,val){ return acc+val;} // => can change to (acc,val)=>acc+val
let answer= array.reduce(sum); // answer is 6

Change to

let array=[1,2,3];
let answer=arrays.reduce((acc,val)=>acc+val);

Also you can use in

1. find max

    let array=[5,4,19,2,7];
    function findMax(acc,val)
    {
     if(val>acc){
       acc=val; 
     }
    }

    let biggest=arrays.reduce(findMax); // 19

2. find an element that not repeated.

    arr = [1, 2, 5, 4, 6, 8, 9, 2, 1, 4, 5, 8, 9]
    v = 0
    for i in range(len(arr)):
    v = v ^ arr[i]
    print(value)  //6

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

You can execute

git status -s

This will show modified files name and then by copying the interested file path you can see changes using git diff

git diff <filepath + filename>

$state.go($state.current, $stateParams, {reload: true, inherit: false});

I would recommend using jQuery with this function:

$(document).ready(function(){
 $('#about').addClass('expand');
});

This will add the expand class to an element with id of about when the dom is ready on page load.

use printf with "%05d" e.g.

printf "%05d" 1

I seem to remember that Internet Explorer gets confused if the accept-charset encoding doesn't match the encoding specified in the content-type header. In your example, you claim the document is sent as UTF-8, but want form submits in ISO-8859-1. Try matching those and see if that solves your problem.

I have changed my 'href' -> 'src'. So from this:

<link rel="stylesheet" href="dist/photoswipe.css">

to this:

<link rel="stylesheet" src="dist/photoswipe.css">

It worked. I don't know why, but it did the job.

As of 2018-04-20 Git for Windows has a bug which effectively limits the file size to 4GB max using that particular implementation (this bug propagates to lfs as well).

If you have PHP installed you could use the builtin server.

php -S 0:8080

This isn't really possible in HTML unless you use absolute positioning or javascript. So one solution would be to give this CSS to #bottom_link:

#bottom_link {
    position:absolute;
    bottom:0;
}

Otherwise you'd have to use some javascript. Here's a jQuery block that should do the trick, depending on the simplicity of the page.

$('#bottom_link').css({
    position: 'relative',
    top: $(this).parent().height() - $(this).height()
});

To create list of lists, you need to separate them with commas, like this

coin_args = [
    ["pennies", '2.5', '50.0', '.01'],
    ["nickles", '5.0', '40.0', '.05'],
    ["dimes", '2.268', '50.0', '.1'],
    ["quarters", '5.67', '40.0', '.25']
]

Honestly, much as I love sed for appropriate tasks, this is definitely a task for perl -- it's truly more powerful for this kind of one-liners, especially to "write it back to where it comes from" (perl's -i switch does it for you, and optionally also lets you keep the old version around e.g. with a .bak appended, just use -i.bak instead).

perl -i.bak -pe 's/\.jpg|\.png|\.gif/.jpg/

rather than intricate work in sed (if even possible there) or awk...

You can use cactoos library with provides reusable object-oriented Java components. OOP is emphasized by this library, so no static methods, NULLs, and so on, only real objects and their contracts (interfaces). A simple operation like reading InputStream, can be performed like that

final InputStream input = ...;
final Bytes bytes = new BytesOf(input);
final byte[] array = bytes.asBytes();
Assert.assertArrayEquals(
    array,
    new byte[]{65, 66, 67}
);

Having a dedicated type Bytes for working with data structure byte[] enables us to use OOP tactics for solving tasks at hand. Something that a procedural "utility" method will forbid us to do. For example, you need to enconde bytes you've read from this InputStream to Base64. In this case you will use Decorator pattern and wrap Bytes object within implementation for Base64. cactoos already provides such implementation:

final Bytes encoded = new BytesBase64(
    new BytesOf(
        new InputStreamOf("XYZ")
    )
);
Assert.assertEquals(new TextOf(encoded).asString(), "WFla");

You can decode them in the same manner, by using Decorator pattern

final Bytes decoded = new Base64Bytes(
    new BytesBase64(
        new BytesOf(
            new InputStreamOf("XYZ")
        )
    )
);
Assert.assertEquals(new TextOf(decoded).asString(), "XYZ");

Whatever your task is you will be able to create own implementation of Bytes to solve it.

You could walk up through the parents, noting their position within their parent, until you arrive at the Form.

Edit: Something like (untested):

public Point GetPositionInForm(Control ctrl)
{
   Point p = ctrl.Location;
   Control parent = ctrl.Parent;
   while (! (parent is Form))
   {
      p.Offset(parent.Location.X, parent.Location.Y);
      parent = parent.Parent;
   }
   return p;
}

Provides a space before %c conversion specifier so that compiler will ignore white spaces. The program may be written as below:

#include <stdio.h>
#include <stdlib.h>
int main()
{
    char ch;
    printf("Enter one char");
    scanf(" %c", &ch); /*Space is given before %c*/
    printf("%c\n",ch);
return 0;
}

Maybe you have no Comments record with such primary key, then you should use this code:

try:
    comment = Comment.objects.get(pk=comment_id)
except Comment.DoesNotExist:
    comment = None

the over partition keyword is as if we are partitioning the data by client_id creation a subset of each client id

select client_id, operation_date,
       row_number() count(*) over (partition by client_id order by client_id ) as operationctrbyclient
from client_operations e
order by e.client_id;

this query will return the number of operations done by the client_id

I was hunting around for an answer to this question. I found this helpful. The pattern wasn't apparent in the documentation for with_items.

https://github.com/ansible/ansible/issues/39389

- hosts: localhost
  connection: local
  gather_facts: no

  tasks:
    - name: set_fact
      set_fact:
        foo: "{{ foo }} + [ '{{ item }}' ]"
      with_items:
        - "one"
        - "two"
        - "three"
      vars:
        foo: []

    - name: Print the var
      debug:
        var: foo

I am guessing that you are running the file using Run | Run File (or shift-F6) rather than Run | Run Main Project. The NetBeans 7.1 help file (F1 is your friend!) states for the Arguments parameter:

Add arguments to pass to the main class during application execution. Note that arguments cannot be passed to individual files.

I verified this with a little snippet of code:

public class Junk
{
    public static void main(String[] args)
    {
        for (String s : args)
            System.out.println("arg -> " + s);
    }
}

I set Run -> Arguments to x y z. When I ran the file by itself I got no output. When I ran the project the output was:

arg -> x
arg -> y
arg -> z

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

The best way is to use this line:

var mapUrl = "http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=16900+North+Bay+Road,+Sunny+Isles+Beach,+FL+33160&aq=0&sll=37.0625,-95.677068&sspn=61.282355,146.513672&ie=UTF8&hq=&hnear=16900+North+Bay+Road,+Sunny+Isles+Beach,+FL+33160&spn=0.01628,0.025663&z=14&iwloc=A&output=embed"

Remember to replace the first and second addresses when necessary.

You can look at work sample

mYear.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View arg1, int item, long arg3) {
                if (mYearSpinnerAdapter.isEnabled(item)) {

                }
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

If you want to create dynamically/runtime data table in VB.Net then you should follow these steps as mentioned below :

• Create Data table object.
• Add columns into that data table object.
• Add Rows with values into the object.

For eg.

Dim dt As New DataTable

dt.Columns.Add("Id", GetType(Integer))
dt.Columns.Add("FirstName", GetType(String))
dt.Columns.Add("LastName", GetType(String))

dt.Rows.Add(1, "Test", "data")
dt.Rows.Add(15, "Robert", "Wich")
dt.Rows.Add(18, "Merry", "Cylon")
dt.Rows.Add(30, "Tim", "Burst")

In addition to what Dario stated about the Delegates you could execute a delegate with several parameters:

Predefine your delegate:

Private Delegate Sub TestThreadDelegate(ByRef goodList As List(Of String), ByVal coolvalue As Integer)

Get a handle to the delegate, create parameters in an array, DynamicInvoke on the Delegate:

Dim tester As TestThreadDelegate = AddressOf Me.testthread
Dim params(1) As Object
params(0) = New List(Of String)
params(1) = 0

tester.DynamicInvoke(params)

Had similar issue that could not be solved by any solution above. My project uses CocoaPods. I noticed that along with errors I got a warning with the following message:

Uncategorized: Target 'Pods' of project 'Pods' was rejected as an implicit dependency for 'Pods.framework' because its architectures 'arm64' didn't contain all required architectures 'armv7 arm64'

So solution was quite simple. For Pods project, change Build Active Architecture Only flag to No and original error went away.

You can use:

$("#tagscloud span").text("Your text here");

The same code will also work for the second case. You could also use:

$("#tagscloud #WebPartCaptionWPQ2").text("Your text here");

This is similar to, but more general than, @Jacob Relkin's solution:

This is ES2015:

const randomChoice = arr => {
    const randIndex = Math.floor(Math.random() * arr.length);
    return arr[randIndex];
};

The code works by selecting a random number between 0 and the length of the array, then returning the item at that index.

Here is another example of a recursive copy function that lets you copy the contents of the directory (including sub-directories) one file at a time, which I used to solve this problem.

import os
import shutil

def recursive_copy(src, dest):
    """
    Copy each file from src dir to dest dir, including sub-directories.
    """
    for item in os.listdir(src):
        file_path = os.path.join(src, item)

        # if item is a file, copy it
        if os.path.isfile(file_path):
            shutil.copy(file_path, dest)

        # else if item is a folder, recurse 
        elif os.path.isdir(file_path):
            new_dest = os.path.join(dest, item)
            os.mkdir(new_dest)
            recursive_copy(file_path, new_dest)

EDIT: If you can, definitely just use shutil.copytree(src, dest). This requires that that destination folder does not already exist though. If you need to copy files into an existing folder, the above method works well!

#i'm also maintaining insertion order here
Map<Integer,ArrayList> d=new LinkedHashMap<>();
for( int i=0; i<2; i++)
{
int id=s.nextInt();
ArrayList al=new ArrayList<>();
al.add(s.next());  //name
al.add(s.next());  //category
al.add(s.nextInt()); //fee
d.put(id, al);
 }

It has at least been suggested, but also rejected. I don't think there is another way, short of repeating the test or re-organizing the code. It is sometimes a bit annoying.

In the rejection message, Mr van Rossum mentions using return, which is really sensible and something I need to remember personally. :)

In kotlin your_edittext.isCursorVisible = false

Your [hidden] will work but you need to check the css:

<input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden" />

And the css:

[hidden] {
  display: none !important;
}

That should work as you want.

This is the way Visual Studio is designed: One solution, one Visual Studio (VS) instance.

Besides switching between solutions in one VS instance, you can also open another VS instance and open your other solution with that one. Next to solutions there are as you said "projects". You can have multiple projects within one solution and therefore view many projects at the same time.

I had the same issue. I think it would be appropriate to check whether your class can be compiled or not. Click recompile (Ctrl+Shift+F9 by default). If its not working then you have to investigate why it isn't compiling.

In my case the code wasn't autocompiling because there were hidden errors with compilation (they weren't shown in logs anywhere and maven clean-install was working). The rootcause was incorrect Project Structure -> Modules configuration, so Intellij Idea wasn't able to build it according to this configuration.

Go to magento/var/report and open the file with the Error log record number name i.e 673618173351 in your case. In that file you can find the complete description of the error.

For log files like system.log and exception.log, go to magento/var/log/.

if you use external libraries in your program and you try to pack all together in a jar file it's not that simple, because of classpath issues etc.

I'd prefer to use OneJar for this issue.

Enable CORS on backend server or add chrome extensions https://chrome.google.com/webstore/search/CORS?utm_source=chrome-ntp-icon and make ON

No,its check like if string is "john" OR "mary" OR "peter" OR "etc."

you should check using ||

Like.,,if(str.equals("john") || str.equals("mary") || str.equals("peter"))

1. Set Custom Structure: /%postname%/

2. Set Category base: . (dot not /)

3. Save. 100% work correctly.

open: function () {

    var win = $(window);

    $(this).parent().css({
        position: 'absolute',
        left: (win.width() - $(this).parent().outerWidth()) / 2,
        top: (win.height() - $(this).parent().outerHeight()) / 2
    });
}

I've made a little modification to split files based on size of each part.

##############################################################################
#.SYNOPSIS
# Breaks a text file into multiple text files in a destination, where each
# file contains a maximum number of lines.
#
#.DESCRIPTION
# When working with files that have a header, it is often desirable to have
# the header information repeated in all of the split files. Split-File
# supports this functionality with the -rc (RepeatCount) parameter.
#
#.PARAMETER Path
# Specifies the path to an item. Wildcards are permitted.
#
#.PARAMETER LiteralPath
# Specifies the path to an item. Unlike Path, the value of LiteralPath is
# used exactly as it is typed. No characters are interpreted as wildcards.
# If the path includes escape characters, enclose it in single quotation marks.
# Single quotation marks tell Windows PowerShell not to interpret any

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

When you make your URL /about-us/ (with the trailing slash), it's easy to start with a single file index.html and then later expand it and add more files (e.g. our-CEO-john-doe.jpg) or even build a hierarchy under it (e.g. /about-us/company/, /about-us/products/, etc.) as needed, without changing the published URL. This gives you a great flexibility.

I wonder why nobody mentioned the Minted package. It has far better syntax highlighting than the LaTeX listing package. It uses Pygments.

$ pip install Pygments

Example in LaTeX:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage{minted}

\begin{document}
\begin{minted}{python}
import numpy as np

def incmatrix(genl1,genl2):
    m = len(genl1)
    n = len(genl2)
    M = None #to become the incidence matrix
    VT = np.zeros((n*m,1), int)  #dummy variable

    #compute the bitwise xor matrix
    M1 = bitxormatrix(genl1)
    M2 = np.triu(bitxormatrix(genl2),1) 

    for i in range(m-1):
        for j in range(i+1, m):
            [r,c] = np.where(M2 == M1[i,j])
            for k in range(len(r)):
                VT[(i)*n + r[k]] = 1;
                VT[(i)*n + c[k]] = 1;
                VT[(j)*n + r[k]] = 1;
                VT[(j)*n + c[k]] = 1;

                if M is None:
                    M = np.copy(VT)
                else:
                    M = np.concatenate((M, VT), 1)

                VT = np.zeros((n*m,1), int)

    return M
\end{minted}
\end{document}

Which results in:

You need to use the flag -shell-escape with the pdflatex command.

For more information: https://www.sharelatex.com/learn/Code_Highlighting_with_minted

You can use the response.text to write to a file:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("resp_text.txt", "w")
file.write(response.text)
file.close()
file = open("resp_content.txt", "w")
file.write(response.text)
file.close()

Maybe you could look at why they are complaining. If a php file has a newline after the ending ?>, php will output it as part of the page. This is not a problem unless you try to send headers after the file is included.

However, the ?> at the end of a php file is optional. No ending ?>, no problem with a newline at the end of the file.

Package version are very important.

I found some stable combination that works on my Windows10 64 bit machine:

pip install numpy-1.12.0+mkl-cp36-cp36m-win64.whl
pip install scipy-0.18.1-cp36-cp36m-win64.whl
pip install matplotlib-2.0.0-cp36-cp36m-win64.whl

A easy way to install pyodbc is by using 'conda'. As conda automatically installs required dependencies including unixodbc.

conda --ugrade all (optional)

then conda install pyodbc

it will install following packages:

libgfortran-ng: 7.2.0-hdf63c60_3 defaults mkl: 2018.0.3-1 defaults mkl_fft: 1.0.2-py36_0 conda-forge mkl_random: 1.0.1-py36_0 conda-forge numpy-base: 1.14.5-py36hdbf6ddf_0 defaults pyodbc: 4.0.17-py36_0 conda-forge unixodbc: 2.3.4-1 conda-forge

public changeAttr(int id)
{
    list.Find(p => p.IdItem == id).FieldToModify = newValueForTheFIeld;
}

With:

• IdItem is the id of the element you want to modify

• FieldToModify is the Field of the item that you want to update.

• NewValueForTheField is exactly that, the new value.

(It works perfect for me, tested and implemented)

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

I tend to use Homebrew on Mac. It will install and configure all the stuff for you.
http://mxcl.github.com/homebrew/

Then you should be able to install it with brew install mcrypt php53-mcrypt and it'll Just Work (tm).

You can replace the 53 with whatever version of PHP you're using, such as php56-mcrypt or php70-mcrypt. If you're not sure, use brew search php.

Do also remember that if you are using the built in Mac PHP it's installed into /usr/bin you can see which php you are using with which php at the terminal and it'll return the path.

Check this:

  let cloned = source.map(x => Object.assign({}, x));

rsync -rvc --delete --size-only --dry-run source dir target dir

Stream::anyMatch

Since Java 8 you could use Stream::anyMatch.

setA.stream().anyMatch(setB::contains)

If you added the key-string pairs in Info.plist (see Murat's answer above ) and still getting the error, try to check if the target you're currently working on has the keys.

In my case I had 2 targets (dev and development). I added the keys in the editor, but it only works for the main target and I was testing on development target. So I had to open XCode, click on the project > Info > Add the key-pair for the development target there.

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

The VirtualHost would look like this:

NameVirtualHost IP_Address:443

<VirtualHost IP_Address:443>
    SSLEngine on
    SSLCertificateFile /etc/pki/tls/certs/ca.crt    # Where "ca" is the name of the Certificate
    SSLCertificateKeyFile /etc/pki/tls/private/ca.key
    ServerAdmin webmaster@domain_name.com
    DocumentRoot /var/www/html
    ServerName www.domain_name.com
    ErrorLog logs/www.domain_name.com-error_log
    CustomLog logs/www.domain_name.com-access_log common
</VirtualHost>

Did your server use the new registration ID returned by the GCM server to your app? I had this problem, if trying to send a message to registration IDs that are given out by the old C2DM server.

And also double check the Sender ID and API_KEY, they must match or else you will get that MismatchSenderId error. In the Google API Console, look at the URL of your project:

https://code.google.com/apis/console/#project:xxxxxxxxxxx

The xxxxxxxxx is the project ID, which is the sender ID.

And make sure the API Key belongs to 'Key for server apps (with IP locking)'

I have spent many hours trying to build a fat static library that will work on armv7, armv7s, and the simulator. Finally found a solution.

The gist is to build the two libraries (one for the device and then one for the simulator) separately, rename them to distinguish from each other, and then lipo -create them into one library.

lipo -create libPhone.a libSimulator.a -output libUniversal.a

I tried it and it works!

For me, this one works well (thanks to the last comments for pointing out the directory /var/lib/docker/):

chroot /var/lib/docker/containers/2465790aa2c4*/root/

Here, 2465790aa2c4 is the short ID of the running container (as displayed by docker ps), followed by a star.

Use "default"!!!

    string myString = default;
    double myDouble = defaul;

    if(!String.IsNullOrEmpty(myString))
       myDouble = 1.5;

    return myDouble;

This is happen because another instance of sql server is running. So you need to kill first then you can able to login to SQL Server.

For that go to Task Manager and Kill or End Task the SQL Server service then go to Services.msc and start the SQL Server service.

"A program doesn't run any faster when it is read from a ".pyc" or ".pyo" file than when it is read from a ".py" file; the only thing that's faster about ".pyc" or ".pyo" files is the speed with which they are loaded. "

If you are using Jackson to deserialize the response body, one very simple solution is to use request.getResponseBodyAsStream() instead of request.getResponseBodyAsString()

The error your seeing is probably due to a non-MySQL created directory in MySQL's data directory. MySQL maps the database structure pretty directly onto the file system, databases are mapped to directories and tables are files in those directories.

The name of the non-working database looks suspiciously like someone has copied the mysql database directory to a backup at some point and left it in MySQL's data directory. This isn't a problem as long as you don't try and use the database for anything. Unfortunately the information schema scans all of the databases it finds and finds that this one isn't a real database and gets upset.

The solution is to find the mysql.bak directory on the hard disk and move it well away from MySQL.

@Entity(name = "someThing") => this name will be used to identify the domain ..this name will only be identified by hql queries ..ie ..name of the domain object

@Table(name = "someThing") => this name will be used to which table referred by domain object..ie ..name of the table

ULTIMATE SOLUTION Detecting if a radio button has been checked using onChang method JQUERY > 3.6

         $('input[type=radio][name=YourRadioName]').change(()=>{
             alert("Hello"); });

Getting the value of the clicked radio button

 var radioval=$('input[type=radio][name=YourRadioName]:checked').val();

I just happened to come by your question and i have a solution. But its in jquery. Its too simple.

$('iframe').contents().find('body').css({"min-height": "100", "overflow" : "hidden"});
setInterval( "$('iframe').height($('iframe').contents().find('body').height() + 20)", 1 );

There you go!

Cheers! :)

Edit: If you have a Rich Text Editor based on the iframe method and not the div method and want it to expand every new line then this code will do the needful.

Even though it's convenient to use, it seems like the convert-to-hash solution costs quite a lot of performance, which was an issue for me.

#!/usr/bin/perl
use Benchmark;
my @list;
for (1..10_000) {
    push @list, $_;
}

timethese(10000, {
  'grep'    => sub {
            if ( grep(/^5000$/o, @list) ) {
                # code
            }
        },
  'hash'    => sub {
            my %params = map { $_ => 1 } @list;
            if ( exists($params{5000}) ) {
                # code
            }
        },
});

Output of benchmark test:

Benchmark: timing 10000 iterations of grep, hash...

Try to toggle height.

function toggleTextArea()
{
  var limitedHeight = '40px';
  var targetEle = document.getElementById("textarea");
  targetEle.style.height = (targetEle.style.height === '') ? limitedHeight : '';
}

$(function (){
    $('body').on('keypress','.sobitie_snses input',function(e){
        if(e.keyCode==13){
            $(this).blur();
            var new_fild =  $(this).clone().val('');
            $(this).parent().append(new_fild);
            $(new_fild).focus();
        }
    });
});

most of error are because U use wrong object to set the prorepty or function. Use console.log(new_fild); to see to what object U try to set the prorepty or function.

The specific problem is that you're declaring a new variable instead of assigning to an existing one:

char * ret = new char[strlen(array) + 1 + 1];
^^^^^^ Remove this

and trying to compare string values by comparing pointers:

if (array!="")     // Wrong - compares pointer with address of string literal
if (array[0] == 0) // Better - checks for empty string

although there's no need to make that comparison at all; the first branch will do the right thing whether or not the string is empty.

The more general problem is that you're messing around with nasty, error-prone C-style string manipulation in C++. Use std::string and it will manage all the memory allocation for you:

std::string appendCharToString(std::string const & s, char a) {
    return s + a;
}

You can check Announcing the official release of the Visual C++ Build Tools 2015 and from this blog, we can know that the Build Tools are the same C++ tools that you get with Visual Studio 2015 but they come in a scriptable standalone installer that only lays down the tools you need to build C++ projects. The Build Tools give you a way to install the tools you need on your build machines without the IDE you don’t need.

Because these components are the same as the ones installed by the Visual Studio 2015 Update 2 setup, you cannot install the Visual C++ Build Tools on a machine that already has Visual Studio 2015 installed. Therefore, it asks you to uninstall your existing VS 2015 when you tried to install the Visual C++ build tools using the standalone installer. Since you already have the VS 2015, you can go to Control Panel—Programs and Features and right click the VS 2015 item and Change-Modify, then check the option of those components that relates to the Visual C++ Build Tools, like Visual C++, Windows SDK… then install them. After the installation is successful, you can build the C++ projects.

In addition to the Javascript solutions above, you can also use an HTML 5 solution by marking the radio buttons as required in the markup. This will eliminate the need for any Javascript and let the browser do the work for you.

See HTML5: How to use the "required" attribute with a "radio" input field for more information on how to do this well.

Let's say you have one more commit at the bottom (oldest), then this becomes pretty easy:

Now, using below will easily server the purpose.

git diff k73ud oldestCommit

In computer terms, new Date() and regular expression solutions are slow! If you want a super-fast (and super-cryptic) one-liner, try this one (assuming m is in Jan=1 format). I keep trying different code changes to get the best performance.

My current fastest version:

After looking at this related question Leap year check using bitwise operators (amazing speed) and discovering what the 25 & 15 magic number represented, I have come up with this optimized hybrid of answers:

function getDaysInMonth(m, y) {
    return m===2 ? y & 3 || !(y%25) && y & 15 ? 28 : 29 : 30 + (m+(m>>3)&1);
}

Given the bit-shifting this obviously assumes that your m & y parameters are both integers, as passing numbers as strings would result in weird results.

JSFiddle: http://jsfiddle.net/TrueBlueAussie/H89X3/22/

JSPerf results: http://jsperf.com/days-in-month-head-to-head/5

For some reason, (m+(m>>3)&1) is more efficient than (5546>>m&1) on almost all browsers.

The only real competition for speed is from @GitaarLab, so I have created a head-to-head JSPerf for us to test on: http://jsperf.com/days-in-month-head-to-head/5

It works based on my leap year answer here: javascript to find leap year this answer here Leap year check using bitwise operators (amazing speed) as well as the following binary logic.

A quick lesson in binary months:

If you interpret the index of the desired months (Jan = 1) in binary you will notice that months with 31 days either have bit 3 clear and bit 0 set, or bit 3 set and bit 0 clear.

Jan = 1  = 0001 : 31 days
Feb = 2  = 0010
Mar = 3  = 0011 : 31 days
Apr = 4  = 0100
May = 5  = 0101 : 31 days
Jun = 6  = 0110
Jul = 7  = 0111 : 31 days
Aug = 8  = 1000 : 31 days
Sep = 9  = 1001
Oct = 10 = 1010 : 31 days
Nov = 11 = 1011
Dec = 12 = 1100 : 31 days

That means you can shift the value 3 places with >> 3, XOR the bits with the original ^ m and see if the result is 1 or 0 in bit position 0 using & 1. Note: It turns out + is slightly faster than XOR (^) and (m >> 3) + m gives the same result in bit 0.

I'm aware this is an old question, but it's one of the first I found when I was looking for an answer to this very question. I haven't seen this solution discussed anywhere else, so let me know if there's something foolish about doing this.

select into is used in pl/sql to set a variable to field values. Instead, use

create table new_table as select * from old_table

Revisited in 2015:

<img src="http://imageurl" style="width: auto; height: auto;max-width: 120px;max-height: 100px">

I've revisited it as all common browsers now have working auto suggested by Cherif above, so that works even better as you don't need to know if image is wider than taller.

older version: If you are limited by box of 120x100 for example you can do

<img src="http://image.url" height="100" style="max-width: 120px">

In order to execute simple queries and return to my shell script, I think this works well:

$ sqlite3 example.db 'SELECT * FROM some_table;'

No one has mentioned using negative inset values for legend. Here is an example, where the legend is to the right of the plot, aligned to the top (using keyword "topright").

# Random data to plot:
A <- data.frame(x=rnorm(100, 20, 2), y=rnorm(100, 20, 2))
B <- data.frame(x=rnorm(100, 21, 1), y=rnorm(100, 21, 1))

# Add extra space to right of plot area; change clipping to figure
par(mar=c(5.1, 4.1, 4.1, 8.1), xpd=TRUE)

# Plot both groups
plot(y ~ x, A, ylim=range(c(A$y, B$y)), xlim=range(c(A$x, B$x)), pch=1,
               main="Scatter plot of two groups")
points(y ~ x, B, pch=3)

# Add legend to top right, outside plot region
legend("topright", inset=c(-0.2,0), legend=c("A","B"), pch=c(1,3), title="Group")

The first value of inset=c(-0.2,0) might need adjusting based on the width of the legend.

Use

=LEFT(B2, 2)*3600000 + MID(B2,4,2) * 60000 + MID(B2,7,2)*1000 + RIGHT(B2,3)

There are two different ways to implement inserting data from one table to another table.

For Existing Table - INSERT INTO SELECT

This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. It is good practice to always list them for readability and scalability purpose.

----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

For Non-Existing Table - SELECT INTO

This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.

----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

Just by adding sudo to command will work, as it would run it as a superuser.

sudo pip install --upgrade pip

It is advised that you should not directly do it though - please see this post

For InnoDB tables, Percona has a recovery tool which may help. It is far from fail-safe or perfect, and how fast you stopped your MySQL server after the accidental deletes has a major impact. If you're quick enough, changes are you can recover quite a bit of data, but recovering all data is nigh impossible.

Of cours, proper daily backups, binlogs, and possibly a replication slave (which won't help for accidental deletes but does help in case of hardware failure) are the way to go, but this tool could enable you to save as much data as possible when you did not have those yet.

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

Try using the net use command in your script to map the share first, because you can provide it credentials. Then, your copy command should use those credentials.

net use \\<network-location>\<some-share> password /USER:username

If you install the third party package:

npm i cordova-check-plugins

You can then run a simple command of

cordova-check-plugins --update=auto --force

Keep in mind forcing anything always comes with potential risks of breaking changes.

As other answers have stated, the connecting NPM packages that manage these plugins also require a consequent update when updating the plugins, so now you can check them with:

npm outdated

And then sweeping update them with

npm update

Now tentatively serve your app again and check all of the things that have potentially gone awry from breaking changes. The joy of software development! :)

In addition to the nconf module mentioned in this answer, and node-config mentioned in this answer, there are also node-iniparser and IniReader, which appear to be simpler .ini configuration file parsers.

Avro is a row-based storage format for Hadoop.

Parquet is a column-based storage format for Hadoop.

If your use case typically scans or retrieves all of the fields in a row in each query, Avro is usually the best choice.

If your dataset has many columns, and your use case typically involves working with a subset of those columns rather than entire records, Parquet is optimized for that kind of work.

I would recommend using imagesLoaded.js javascript library.

Why not use jQuery's $(window).load()?

As ansered on https://stackoverflow.com/questions/26927575/why-use-imagesloaded-javascript-library-versus-jquerys-window-load/26929951

It's a matter of scope. imagesLoaded allows you target a set of images, whereas $(window).load() targets all assets — including all images, objects, .js and .css files, and even iframes. Most likely, imagesLoaded will trigger sooner than $(window).load() because it is targeting a smaller set of assets.

Other good reasons to use imagesloaded

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.

Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597

This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.

Update:

To set this configuration, add the following attribute to the modal div:

[config]="{focus: false}"

Update 2:

To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.

 ngAfterViewChecked() {
    // This dirty hack is needed to force focus on an input element of a modal.
    if (this.el.nativeElement.classList.contains('ng-untouched')) {
        this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
    }
}

Try the following function implemented in Swift 3.0 and above

func delayWithSeconds(_ seconds: Double, completion: @escaping () -> ()) {
    DispatchQueue.main.asyncAfter(deadline: .now() + seconds) { 
        completion()
    }
}

Usage

delayWithSeconds(1) {
   //Do something
}

I'm not entirely sure what you mean by "current milliseconds" but I'll assume it's the number of milliseconds since the "epoch," namely midnight, January 1, 1970 UTC.

If you want to find the number of milliseconds since the epoch right now, then use System.currentTimeMillis() as Anubian Noob has pointed out. If so, there's no reason to use any of the new java.time APIs to do this.

However, maybe you already have a LocalDateTime or similar object from somewhere and you want to convert it to milliseconds since the epoch. It's not possible to do that directly, since the LocalDateTime family of objects has no notion of what time zone they're in. Thus time zone information needs to be supplied to find the time relative to the epoch, which is in UTC.

Suppose you have a LocalDateTime like this:

LocalDateTime ldt = LocalDateTime.of(2014, 5, 29, 18, 41, 16);

You need to apply the time zone information, giving a ZonedDateTime. I'm in the same time zone as Los Angeles, so I'd do something like this:

ZonedDateTime zdt = ldt.atZone(ZoneId.of("America/Los_Angeles"));

Of course, this makes assumptions about the time zone. And there are edge cases that can occur, for example, if the local time happens to name a time near the Daylight Saving Time (Summer Time) transition. Let's set these aside, but you should be aware that these cases exist.

Anyway, if you can get a valid ZonedDateTime, you can convert this to the number of milliseconds since the epoch, like so:

long millis = zdt.toInstant().toEpochMilli();

While installing the node modules for mocha I had tried the below commands

• npm install
• npm install mocha
• npm install --save-dev mocha
• npm install mocha -g # to install it globally also

and on running or executing the mocha test I was trying

• mocha test
• npm run test
• mocha test test\index.test.js
• npm test

but I was getting the below error as:

'Mocha' is not recognized as internal or external command

So , after trying everything it came out to be just set the path to environment variables under the System Variables as:

C:\Program Files\nodejs\

and it worked :)

Keep in mind that MySQL has a maximum row size limit

The internal representation of a MySQL table has a maximum row size limit of 65,535 bytes, not counting BLOB and TEXT types. BLOB and TEXT columns only contribute 9 to 12 bytes toward the row size limit because their contents are stored separately from the rest of the row. Read more about Limits on Table Column Count and Row Size.

Maximum size a single column can occupy, is different before and after MySQL 5.0.3

Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 255 before MySQL 5.0.3, and 0 to 65,535 in 5.0.3 and later versions. The effective maximum length of a VARCHAR in MySQL 5.0.3 and later is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used.

However, note that the limit is lower if you use a multi-byte character set like utf8 or utf8mb4.

Use TEXT types inorder to overcome row size limit.

The four TEXT types are TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. These correspond to the four BLOB types and have the same maximum lengths and storage requirements.

Basically $(this).fadeOut().next().fadeIn(); is what you require

Use: https://wa.me/1XXXXXXXXXX

Don't use: https://wa.me/+001-(XXX)XXXXXXX

The pre-filled message will automatically appear in the text field of a chat. Use https://wa.me/whatsappphonenumber?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and urlencodedtext is the URL-encoded pre-filled message.

Example: https://wa.me/1XXXXXXXXXX?text=I'm%20interested%20in%20your%20car%20for%20sale

To create a link with just a pre-filled message, use https://wa.me/?text=urlencodedtext

Example: https://wa.me/?text=I'm%20inquiring%20about%20the%20apartment%20listing`

After clicking on the link, you’ll be shown a list of contacts you can send your message to.

You need to implement RefreshTokenProvider. First create class for RefreshTokenProvider ie.

public class ApplicationRefreshTokenProvider : AuthenticationTokenProvider
{
    public override void Create(AuthenticationTokenCreateContext context)
    {
        // Expiration time in seconds
        int expire = 5*60;
        context.Ticket.Properties.ExpiresUtc = new DateTimeOffset(DateTime.Now.AddSeconds(expire));
        context.SetToken(context.SerializeTicket());
    }

    public override void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);
    }
}

Then add instance to OAuthOptions.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/authenticate"),
    Provider = new ApplicationOAuthProvider(),
    AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(expire),
    RefreshTokenProvider = new ApplicationRefreshTokenProvider()
};

You could use iotop. It doesn't rely on a kernel patch. It Works with stock Ubuntu kernel

There is a package for it in the Ubuntu repos. You can install it using

sudo apt-get install iotop

Shortest Yet !!!

=f.hidden_field :title, :value => "some value"

Shorter, DRYer and perhaps more obvious.

Of course with ruby 1.9 and the new hash format we can go 3 characters shorter with...

=f.hidden_field :title, value: "some value"

Inside class definitions you can only declare static members. They have to be defined outside of the class. For compile-time integral constants the standard makes the exception that you can "initialize" members. It's still not a definition, though. Taking the address would not work without definition, for example.

I'd like to mention that I don't see the benefit of using std::string over const char[] for constants. std::string is nice and all but it requires dynamic initialization. So, if you write something like

const std::string foo = "hello";

at namespace scope the constructor of foo will be run right before execution of main starts and this constructor will create a copy of the constant "hello" in the heap memory. Unless you really need RECTANGLE to be a std::string you could just as well write

// class definition with incomplete static member could be in a header file
class A {
    static const char RECTANGLE[];
};

// this needs to be placed in a single translation unit only
const char A::RECTANGLE[] = "rectangle";

There! No heap allocation, no copying, no dynamic initialization.

Cheers, s.

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

Weak Reference http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/ref/WeakReference.html

Principle: weak reference is related to garbage collection. Normally, object having one or more reference will not be eligible for garbage collection.
The above principle is not applicable when it is weak reference. If an object has only weak reference with other objects, then its ready for garbage collection.

Let's look at the below example: We have an Map with Objects where Key is reference a object.

import java.util.HashMap;   
public class Test {

    public static void main(String args[]) {
        HashMap<Employee, EmployeeVal> aMap = new 
                       HashMap<Employee, EmployeeVal>();

        Employee emp = new Employee("Vinoth");
        EmployeeVal val = new EmployeeVal("Programmer");

        aMap.put(emp, val);

        emp = null;

        System.gc();
        System.out.println("Size of Map" + aMap.size());

    }
}

Now, during the execution of the program we have made emp = null. The Map holding the key makes no sense here as it is null. In the above situation, the object is not garbage collected.

WeakHashMap

WeakHashMap is one where the entries (key-to-value mappings) will be removed when it is no longer possible to retrieve them from the Map.

Let me show the above example same with WeakHashMap

import java.util.WeakHashMap;

public class Test {

    public static void main(String args[]) {
        WeakHashMap<Employee, EmployeeVal> aMap = 
                    new WeakHashMap<Employee, EmployeeVal>();

        Employee emp = new Employee("Vinoth");
        EmployeeVal val = new EmployeeVal("Programmer");

        aMap.put(emp, val);

        emp = null;

        System.gc();
        int count = 0;
        while (0 != aMap.size()) {
            ++count;
            System.gc();
        }
        System.out.println("Took " + count
                + " calls to System.gc() to result in weakHashMap size of : "
                + aMap.size());
    }
}

Output: Took 20 calls to System.gc() to result in aMap size of : 0.

WeakHashMap has only weak references to the keys, not strong references like other Map classes. There are situations which you have to take care when the value or key is strongly referenced though you have used WeakHashMap. This can avoided by wrapping the object in a WeakReference.

import java.lang.ref.WeakReference;
import java.util.HashMap;

public class Test {

    public static void main(String args[]) {
        HashMap<Employee, EmployeeVal> map = 
                      new HashMap<Employee, EmployeeVal>();
        WeakReference<HashMap<Employee, EmployeeVal>> aMap = 
                       new WeakReference<HashMap<Employee, EmployeeVal>>(
                map);

        map = null;

        while (null != aMap.get()) {
            aMap.get().put(new Employee("Vinoth"),
                    new EmployeeVal("Programmer"));
            System.out.println("Size of aMap " + aMap.get().size());
            System.gc();
        }
        System.out.println("Its garbage collected");
    }
}

Soft References.

Soft Reference is slightly stronger that weak reference. Soft reference allows for garbage collection, but begs the garbage collector to clear it only if there is no other option.

The garbage collector does not aggressively collect softly reachable objects the way it does with weakly reachable ones -- instead it only collects softly reachable objects if it really "needs" the memory. Soft references are a way of saying to the garbage collector, "As long as memory isn't too tight, I'd like to keep this object around. But if memory gets really tight, go ahead and collect it and I'll deal with that." The garbage collector is required to clear all soft references before it can throw OutOfMemoryError.

The easiest solution is to convert your categorical variable to a factor prior to the subsetting. Bottomline is that you need a factor variable with exact the same levels in all your subsets.

library(ggplot2)
dataset <- data.frame(category = rep(LETTERS[1:5], 100), 
    x = rnorm(500, mean = rep(1:5, 100)), y = rnorm(500, mean = rep(1:5, 100)))
dataset$fCategory <- factor(dataset$category)
subdata <- subset(dataset, category %in% c("A", "D", "E"))

With a character variable

ggplot(dataset, aes(x = x, y = y, colour = category)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = category)) + geom_point()

With a factor variable

ggplot(dataset, aes(x = x, y = y, colour = fCategory)) + geom_point()
ggplot(subdata, aes(x = x, y = y, colour = fCategory)) + geom_point()

Using lxml:

from lxml import etree

# create XML 
root = etree.Element('root')
root.append(etree.Element('child'))
# another child with text
child = etree.Element('child')
child.text = 'some text'
root.append(child)

# pretty string
s = etree.tostring(root, pretty_print=True)
print s

Output:

<root>
  <child/>
  <child>some text</child>
</root>

LTRIM(RTRIM(FCT_TYP_CD)) & ') AND (' & LTRIM(RTRIM(DEP_TYP_ID)) & ')'

I think you're missing a ) on both of the trims. Some SQL versions support just TRIM which does both L and R trims...

First things first, i'd not like that as a user.

The best way to do is probably using a small flash applet that plays your sound in the background.

As it has more pixels in height, things like GCRectMake that use coordinates won't work seamlessly between versions, as it happened when we got the Retina.

Well, they do work the same with Retina displays - it's just that 1 unit in the CoreGraphics coordinate system will correspond to 2 physical pixels, but you don't/didn't have to do anything, the logic stayed the same. (Have you actually tried to run one of your non-retina apps on a retina iPhone, ever?)

For the actual question: that's why you shouldn't use explicit CGRectMakes and co... That's why you have stuff like [[UIScreen mainScreen] applicationFrame].

in HTML, you do this backwards: You define a text input:

<input type="text" list="browsers" />

and attach a datalist to it. (note the list attribute of the input).

<datalist id="browsers">
  <option value="Internet Explorer">
  <option value="Firefox">
  <option value="Chrome">
  <option value="Opera">
  <option value="Safari">
</datalist> 

This would have been a comment under Brad's answer, but I don't have a high enough reputation.

Recently I found that I needed the key of the multidimensional array too, i.e., it wasn't just an index for the array, in the foreach loop.

In order to achieve that, you could use something very similar to the accepted answer, but instead split the key and value as follows

foreach ($mda as $mdaKey => $mdaData) {
    echo $mdaKey . ": " . $mdaData["value"];
}

Hope that helps someone.

I think the closest to the OP's intuition is an inline if statement:

df['que'] = (df['one'] if ((df['one'] >= df['two']) and (df['one'] <= df['three'])) 

.val() is for input elements, use .html() instead

Vertical tab was used to speed up printer vertical movement. Some printers used special tab belts with various tab spots. This helped align content on forms. VT to header space, fill in header, VT to body area, fill in lines, VT to form footer. Generally it was coded in the program as a character constant. From the keyboard, it would be CTRL-K.

I don't believe anyone would have a reason to use it any more. Most forms are generated in a printer control language like postscript.

@Talvi Wilson noted it used in python '\v'.

print("hello\vworld")

Output:

hello
     world

The above output appears to result in the default vertical size being one line. I have tested with perl "\013" and the same output occurs. This could be used to do line feed without a carriage return on devices with convert linefeed to carriage-return + linefeed.

Or if you need to set the value of found:

found = Value1.StartsWith("abc")

Edit: Given your edit, I would do something like:

found = Value1.Substring(0, 5).Contains("abc")

For me only way to delete project was switch language to English (UK) - from Polish and then button "DELETE" worked. If anyone have problem with not working or missing options in Google Cloud Platform I suggest switching to english after that everything works like charm...

Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!

import pandas as pd
import numpy as np

df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )

# Create an index list from the set of dates in both data frames
Index = list(set(list(df1.index) + list(df2.index)))
Index.sort()

df3 = pd.DataFrame({'df1': [df1.loc[Date, 'c'] if Date in df1.index else np.nan for Date in Index],\
                'df2': [df2.loc[Date, 'c'] if Date in df2.index else np.nan for Date in Index],},\
                index = Index)

df3

keystore simply stores private keys, wheras truststore stores public keys. You will want to generate a java certificate for SSL communication. You can use a keygen command in windows, this will probably be the most easy solution.

Try this with below RE

• \b start of word word boundary
• \W+ any word character
• \1 same word matched already
• \b end of word

• ()* Repeating again

  public static void main(String[] args) {
  
      String regex = "\\b(\\w+)(\\b\\W+\\b\\1\\b)*";//  "/* Write a RegEx matching repeated words here. */";
      Pattern p = Pattern.compile(regex, Pattern.CASE_INSENSITIVE/* Insert the correct Pattern flag here.*/);
  
      Scanner in = new Scanner(System.in);
  
      int numSentences = Integer.parseInt(in.nextLine());
  
      while (numSentences-- > 0) {
          String input = in.nextLine();
  
          Matcher m = p.matcher(input);
  
          // Check for subsequences of input that match the compiled pattern
          while (m.find()) {
              input = input.replaceAll(m.group(0),m.group(1));
          }
  
          // Prints the modified sentence.
          System.out.println(input);
      }
  
      in.close();

You will need to have a function which replaces \n to \\n in case data is not a string literal.

function jsonEscape(str)  {
    return str.replace(/\n/g, "\\\\n").replace(/\r/g, "\\\\r").replace(/\t/g, "\\\\t");
}

var data = '{"count" : 1, "stack" : "sometext\n\n"}';
var dataObj = JSON.parse(jsonEscape(data));

Resulting dataObj will be

Object {count: 1, stack: "sometext\n\n"}

The most basic and easiest way to understand (I think):

import java.util.Scanner;

public class ToUpperCase {
    static Scanner kb = new Scanner(System.in);

    public static String capitalize(String str){
        /* Changes 1st letter of every word 
           in a string to upper case
         */
        String[] ss = str.split(" ");
        StringBuilder[] sb = new StringBuilder[ss.length];
        StringBuilder capped = new StringBuilder("");
        str = "";

        // Capitalise letters
        for (int i = 0; i < ss.length; i++){
            sb[i] = new StringBuilder(ss[i]); // Construct and assign
            str += Character.toUpperCase(ss[i].charAt(0)); // Only caps
            //======================================================//

            // Replace 1st letters with cap letters
            sb[i].setCharAt(0, str.charAt(i)); 
            capped.append(sb[i].toString() + " ");  // Formatting
        }
        return capped.toString();
    }

    public static void main(String[] args){
        System.out.println(capitalize(kb.nextLine()));
    }
}

SQL*Plus uses &1, &2... &n to access the parameters.

Suppose you have the following script test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

Edit:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

so that your login/password won't be visible with another session's ps

Use the code below. See it working here http://jsfiddle.net/usmanhalalit/3HPz4/

     });

     $('#name2').change(function(){
         $('#name option[value=""]').attr('selected','selected');
     });
 });

Use Ajax for this.

Build a function that will fetch the current page via ajax, but not the whole page, just the div in question from the server. The data will then (again via jQuery) be put inside the same div in question and replace old content with new one.

Relevant function:

http://api.jquery.com/load/

e.g.

$('#thisdiv').load(document.URL +  ' #thisdiv');

Note, load automatically replaces content. Be sure to include a space before the id selector.

Your function worked for me after changing its declaration to this ...

Function processArr(Arr As Variant) As String

You could also consider a ParamArray like this ...

Function processArr(ParamArray Arr() As Variant) As String
    'Dim N As Variant
    Dim N As Long
    Dim finalStr As String
    For N = LBound(Arr) To UBound(Arr)
        finalStr = finalStr & Arr(N)
    Next N
    processArr = finalStr
End Function

And then call the function like this ...

processArr("foo", "bar")

Remove the server from IDE and install again to it.

If you want to post parameter in okhttp as body content which can be encrypted string with content-type as "application/x-www-form-urlencoded" you can first use URLEncoder to encode the data and then use :

final MediaType MEDIA_TYPE_MARKDOWN = MediaType.parse("application/x-www-form-urlencoded");

okhttp3.Request request = new okhttp3.Request.Builder()
    .url(urlOfServer)
    .post(RequestBody.create(MEDIA_TYPE_MARKDOWN, yourBodyDataToPostOnserver))
    .build();

you can add header according to your requirement.

You can try this it has worked for me.

Using anytime package:

library(anytime)

anydate("2009-01")
# [1] "2009-01-01"

It should be like that

public static void main(String[] args) {
        EchoServer0 e = new EchoServer0();
        // TODO Auto-generated method stub
        e.listen();
}

Your variable of type Object truly doesn't have such a method, but the type EchoServer0 you define above certainly has.

No need to mess around with settings just remove the quotes and spaces from the font-family:

this

body {font-family: "DroidSerif Regular", serif; }

becomes this

body {font-family: DroidSerifRegular, serif; }

Default Export (export default)

// MyClass.ts -- using default export
export default class MyClass { /* ... */ }

The main difference is that you can only have one default export per file and you import it like so:

import MyClass from "./MyClass";

You can give it any name you like. For example this works fine:

import MyClassAlias from "./MyClass";

Named Export (export)

// MyClass.ts -- using named exports
export class MyClass { /* ... */ }
export class MyOtherClass { /* ... */ }

When you use a named export, you can have multiple exports per file and you need to import the exports surrounded in braces:

import { MyClass } from "./MyClass";

Note: Adding the braces will fix the error you're describing in your question and the name specified in the braces needs to match the name of the export.

Or say your file exported multiple classes, then you could import both like so:

import { MyClass, MyOtherClass } from "./MyClass";
// use MyClass and MyOtherClass

Or you could give either of them a different name in this file:

import { MyClass, MyOtherClass as MyOtherClassAlias } from "./MyClass";
// use MyClass and MyOtherClassAlias

Or you could import everything that's exported by using * as:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass and MyClasses.MyOtherClass here

Which to use?

In ES6, default exports are concise because their use case is more common; however, when I am working on code internal to a project in TypeScript, I prefer to use named exports instead of default exports almost all the time because it works very well with code refactoring. For example, if you default export a class and rename that class, it will only rename the class in that file and not any of the other references in other files. With named exports it will rename the class and all the references to that class in all the other files.

It also plays very nicely with barrel files (files that use namespace exports—export *—to export other files). An example of this is shown in the "example" section of this answer.

Note that my opinion on using named exports even when there is only one export is contrary to the TypeScript Handbook—see the "Red Flags" section. I believe this recommendation only applies when you are creating an API for other people to use and the code is not internal to your project. When I'm designing an API for people to use, I'll use a default export so people can do import myLibraryDefaultExport from "my-library-name";. If you disagree with me about doing this, I would love to hear your reasoning.

That said, find what you prefer! You could use one, the other, or both at the same time.

Additional Points

A default export is actually a named export with the name default, so if the file has a default export then you can also import by doing:

import { default as MyClass } from "./MyClass";

And take note these other ways to import exist: 

import MyDefaultExportedClass, { Class1, Class2 } from "./SomeFile";
import MyDefaultExportedClass, * as Classes from "./SomeFile";
import "./SomeFile"; // runs SomeFile.js without importing any exports

Use pwd to search from any directory you are in, recursing downward

grep -rnw `pwd` -e "pattern"

Update Depending on the version of grep you are using, you can omit pwd. On newer versions . seems to be the default case for grep if no directory is given thus:

grep -rnw -e "pattern"

or

grep -rnw "pattern"

will do the same thing as above!

 * The cost to add or delete an element into a known location in the list 
   (i.e. if you have an iterator to the location) is O(1). If you don't 
   know the location, then you need to traverse the list to the location
   of deletion/insertion, which takes O(n) time. 

** The deletion cost is O(log n) for the minimum or maximum, O(n) for an
   arbitrary element.

In the spirit of providing functionality, go to your .profile or .bashrc file located at /home/usr/ and at the bottom add the line:

alias enw='emacs -nw'

Now each time you open a terminal session you just type, for example, enw and you have the Emacs no-window option with three letters :).

The performance of the suggested answer is fine. According to the MongoDB documentation:

When a $sort immediately precedes a $limit, the optimizer can coalesce the $limit into the $sort. This allows the sort operation to only maintain the top n results as it progresses, where n is the specified limit, and MongoDB only needs to store n items in memory.

Changed in version 4.0.

So in the case of

db.collection.find().sort({age:-1}).limit(1)

we get only the highest element WITHOUT sorting the collection because of the mentioned optimization.

You can have text value of #Crd in its variable .

$(document).on('click', '#Crd', function () {
     var Crd = $( "#Crd option:selected" ).text();
});

The "best" way to share a Jupyter notebook is to simply to place it on GitHub (and view it directly) or some other public link and use the Jupyter Notebook Viewer. When privacy is more of an issue then there are alternatives but it's certainly more complex; there's no built-in way to do this in Jupyter alone, but a couple of options are:

Host your own nbviewer

GitHub and the Jupyter Notebook Veiwer both use the same tool to render .ipynb files into static HTML, this tool is nbviewer.

The installation instructions are more complex than I'm willing to go into here but if your company/team has a shared server that doesn't require password access then you could host the nbviewer on that server and direct it to load from your credentialed server. This will probably require some more advanced configuration than you're going to find in the docs.

Set up a deployment script

If you don't necessarily need live updating HTML then you could set up a script on your credentialed server that will simply use Jupyter's built-in export options to create the static HTML files and then send those to a more publicly accessible server.

Not only check but GETTING admin rights automatically
aka Automatic UAC for Win 7/8/8.1 ff.: The following is a really cool one with one more feature: This batch snippet does not only check for admin rights, but gets them automatically! (and tests before, if living on an UAC capable OS.)

With this trick you don´t need longer to right klick on your batch file "with admin rights". If you have forgotten, to start it with elevated rights, UAC comes up automatically! Moreoever, at first it is tested, if the OS needs/provides UAC, so it behaves correct e.g. for Win 2000/XP until Win 8.1- tested.

@echo off
REM Quick test for Windows generation: UAC aware or not ; all OS before NT4 ignored for simplicity
SET NewOSWith_UAC=YES
VER | FINDSTR /IL "5." > NUL
IF %ERRORLEVEL% == 0 SET NewOSWith_UAC=NO
VER | FINDSTR /IL "4." > NUL
IF %ERRORLEVEL% == 0 SET NewOSWith_UAC=NO


REM Test if Admin
CALL NET SESSION >nul 2>&1
IF NOT %ERRORLEVEL% == 0 (

    if /i "%NewOSWith_UAC%"=="YES" (
        rem Start batch again with UAC
        echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
        echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"
        "%temp%\getadmin.vbs"
        del "%temp%\getadmin.vbs"
        exit /B
    )

    rem Program will now start again automatically with admin rights! 
    rem pause
    goto :eof
)

The snippet merges some good batch patterns together, especially (1) the admin test in this thread by Ben Hooper and (2) the UAC activation read on BatchGotAdmin and cited on the batch site by robvanderwoude (respect). (3) For the OS identificaton by "VER | FINDSTR pattern" I just don't find the reference.)

(Concerning some very minor restrictions, when "NET SESSION" do not work as mentioned in another answer- feel free to insert another of those commands. For me running in Windows safe mode or special standard services down and such are not an important use cases- for some admins maybe they are.)

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

                {
                    //do your stuff here
                    company.Id= 2;
                    company.Name= "Sample"
                }

Profiting from the MS Excel 365 function UNIQUE()

In order to enrich the valid solutions above:

Sub ExampleCall()
Dim rng As Range: Set rng = Sheet1.Range("A2:A11")   ' << change to your sheet's Code(Name)
Dim a: a = rng
a = getUniques(a)
arrInfo a
End Sub

Function getUniques(a, Optional ZeroBased As Boolean = True)
Dim tmp: tmp = Application.Transpose(WorksheetFunction.Unique(a))
If ZeroBased Then ReDim Preserve tmp(0 To UBound(tmp) - 1)
getUniques = tmp
End Function

If you want to update the app icon in the taskbar, then Update following in main.js (if using typescript then main.ts)

win.setIcon(path.join(__dirname, '/src/assets/logo-small.png'));

__dirname points to the root directory (same directory as package.json) of your application.

As a general rule, when on Debian or Ubuntu and you're missing a development file (or any other file for that matter), use apt-file to figure out which package provides that file:

~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h

A quick glance at each of the packages that are returned by the command, using apt show will tell you which among the packages is the one you're looking for:

~ apt show libssl-dev
Package: libssl-dev

N: There is 1 additional record. Please use the '-a' switch to see it

You can do it if you wrap your text into a span like:

a {_x000D_
  color: red;_x000D_
  text-decoration: underline;_x000D_
}_x000D_
span {_x000D_
  color: blue;_x000D_
  text-decoration: none;_x000D_
}

<a href="#">_x000D_
  <span>Text</span>_x000D_
</a>

If you are using an MVC framework with routes and actions:

$(document).ready(function () {
    $('a[href="' + this.location.pathname + '"]').parent().addClass('active');
});

As illustrated in this answer by Christian Landgren: https://stackoverflow.com/a/13375529/101662

You have invalid chars in your source. If you don't have any valid non ascii chars in your source, maybe in a double quoted string literal, you can simply convert your file back to ascii with:

tr -cd '\11\12\15\40-\176' < old.c > new.c

Edit: method with iconv will stop at wrong chars which makes no sense. The above command line is working with the example file. Good luck :-)

This worked for me. It's simple for simple objects.

class Person {_x000D_
  constructor(firstName, lastName) {_x000D_
    this.firstName = firstName;_x000D_
    this.lastName = lastName;_x000D_
  }_x000D_
  getFullName() {_x000D_
    return this.lastName + " " + this.firstName;_x000D_
  }_x000D_
_x000D_
  static class(obj) {_x000D_
    return new Person(obj.firstName, obj.lastName);_x000D_
  }_x000D_
}_x000D_
_x000D_
var person1 = {_x000D_
  lastName: "Freeman",_x000D_
  firstName: "Gordon"_x000D_
};_x000D_
_x000D_
var gordon = Person.class(person1);_x000D_
console.log(gordon.getFullName());

I was also searching for a simple solution, and this is what I came up with, based on all other answers and my research. Basically, class Person has another constructor, called 'class' which works with a generic object of the same 'format' as Person. I hope this might help somebody as well.

Server side

It depends on which language you use.

In Java/Java EE:

• Jetty 7.0 supports it (very easy to use) V 7.5 supports RFC6455 - Jetty 9.1 supports javax.websocket / JSR 356)
• GlassFish 3.0 (very low level and sometimes complex), Glassfish 3.1 has new refactored Websocket Support which is more developer friendly V 3.1.2 supports RFC6455
• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete. See Arun GUPTA's article WebSocket and Java EE 7 - Getting Ready for JSR 356 (TOTD #181) and QCon presentation (from 00:37:36 to 00:46:53) for more information on progress. You can also look at Java websocket SDK.

I would use return null; to indicate that there is no data to be returned

self.view.backgroundColor = UIColor.redColor()

In Swift 3:

self.view.backgroundColor = UIColor.red

passing the xml content as string.

table1 

ID   int
XML  CLOB



import oracle.jdbc.OraclePreparedStatement;
/*
Your Code
*/
 void insert(int id, String xml){
    try {
        String sql = "INSERT INTO table1(ID,XML) VALUES ("
                + id
                + "', ? )";
        PreparedStatement ps = conn.prepareStatement(sql);
        ((OraclePreparedStatement) ps).setStringForClob(1, xml);
        ps.execute();
        result = true;
        } catch (Exception e) {
        e.printStackTrace();
    }
  }

Another example of the solution. Will look like the following

CodePen link there.

  <choose-file layout="row">
    <input id="fileInput" type="file" class="ng-hide">
    <md-input-container flex class="md-block">
      <input type="text" ng-model="fileName" disabled>
      <div class="hint">Select your file</div>
    </md-input-container>
    <div>
      <md-button id="uploadButton" class="md-fab md-mini">
        <md-icon class="material-icons">attach_file</md-icon>
      </md-button>
    </div>
  </choose-file>   

.directive('chooseFile', function() {
    return {
      link: function (scope, elem, attrs) {
        var button = elem.find('button');
        var input = angular.element(elem[0].querySelector('input#fileInput'));

        button.bind('click', function() {
          input[0].click();
        });

        input.bind('change', function(e) {
          scope.$apply(function() {
            var files = e.target.files;
            if (files[0]) {
              scope.fileName = files[0].name;
            } else {
              scope.fileName = null;
            }
          });
        });
      }
    };
  });

Hope it helps!

Create Border

Create an xml file (e.g. "frame_image_view.xml") with the following content in your drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="@dimen/borderThickness"
        android:color="@color/borderColor" />
    <padding
        android:bottom="@dimen/borderThickness"
        android:left="@dimen/borderThickness"
        android:right="@dimen/borderThickness"
        android:top="@dimen/borderThickness" />
    <corners android:radius="1dp" /> <!-- remove line to get sharp corners -->
</shape>

Replace @dimen/borderThickness and @color/borderColor with whatever you want or add corresponding dimen / color.

Add the Drawable as background to your ImageView:

<ImageView
        android:id="@+id/my_image_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/frame_image_view"
        android:cropToPadding="true"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter" />

You have to use android:cropToPadding="true", otherwise the defined padding has no effect. Alternatively use android:padding="@dimen/borderThickness" in your ImageView to achieve the same. If the border frames the parent instead of your ImageView, try to use android:adjustViewBounds="true".

Change Color of Border

The easiest way to change your border color in code is using the tintBackgound attribute.

ImageView img = findViewById(R.id.my_image_view);
img.setBackgroundTintList(ColorStateList.valueOf(Color.RED); // changes border color to red

or

ImageView img = findViewById(R.id.my_image_view);
img.setBackgroundTintList(getColorStateList(R.color.newColor));

Don't forget to define your newColor.

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.

Define the Entity class in Hibernate.cfg.xml

<mapping class="com.supernt.Department"/>

While creating the sessionFactory object Load the Configuration file Like

SessionFactory factory = new AnnotationConfiguration().configure("hibernate.cfg.xml").buildSessionFactory();

The previous answers explain why implementing an interface explicitly in C# may be preferrable (for mostly formal reasons). However, there is one situation where explicit implementation is mandatory: In order to avoid leaking the encapsulation when the interface is non-public, but the implementing class is public.

// Given:
internal interface I { void M(); }

// Then explicit implementation correctly observes encapsulation of I:
// Both ((I)CExplicit).M and CExplicit.M are accessible only internally.
public class CExplicit: I { void I.M() { } }

// However, implicit implementation breaks encapsulation of I, because
// ((I)CImplicit).M is only accessible internally, while CImplicit.M is accessible publicly.
public class CImplicit: I { public void M() { } }

The above leakage is unavoidable because, according to the C# specification, "All interface members implicitly have public access." As a consequence, implicit implementations must also give public access, even if the interface itself is e.g. internal.

Implicit interface implementation in C# is a great convenience. In practice, many programmers use it all the time/everywhere without further consideration. This leads to messy type surfaces at best and leaked encapsulation at worst. Other languages, such as F#, don't even allow it.

Alias version of Adam's updated answer:

You must write correct full path. Don't use '~/Library/Android/sdk'

vi ~/.bashrc

export ANDROID_HOME=/Users/{UserName}/Library/Android/sdk
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

source ~/.bashrc

You'll want to use Get-ChildItem to recursively get all folders and files first. And then pipe that output into a Where-Object clause which only take the files.

# one of several ways to identify a file is using GetType() which
# will return "FileInfo" or "DirectoryInfo"
$files = Get-ChildItem E:\ -Recurse | Where-Object {$_.GetType().Name -eq "FileInfo"} ;

foreach ($file in $files) {
  echo $file.FullName ;
}

To avoid error, an important point about the new dataset is the name of independent variable. It must be the same as reported in the model. Another way is to nest the two function without creating a new dataset

model <- lm(Coupon ~ Total, data=df)
predict(model, data.frame(Total=c(79037022, 83100656, 104299800)))

Pay attention on the model. The next two commands are similar, but for predict function, the first work the second don't work.

model <- lm(Coupon ~ Total, data=df) #Ok
model <- lm(df$Coupon ~ df$Total) #Ko

Actually you cannot set multiple headers Access-Control-Allow-Origin (or at least it won't work in all browsers). Instead you can conditionally set an environment variable and then use it in Header directive:

SetEnvIf Origin "^(https?://localhost|https://[a-z]+\.my\.base\.domain)$" ORIGIN_SUB_DOMAIN=$1
Header set Access-Control-Allow-Origin: "%{ORIGIN_SUB_DOMAIN}e" env=ORIGIN_SUB_DOMAIN

So in this example the response header will be added only if a request header Origin matches RegExp: ^(https?://localhost|https://[a-z]+\.my\.base\.domain)$ (it basically means localhost over HTTP or HTTPS and *.my.base.domain over HTTPS).

Remember to enable setenvif module.

Docs:

• http://httpd.apache.org/docs/2.2/mod/mod_setenvif.html#setenvif
• http://httpd.apache.org/docs/2.2/mod/mod_headers.html#header

BTW. The }e in %{ORIGIN_SUB_DOMAIN}e is not a typo. It's how you use environment variable in Header directive.

We found a different solution to a problem with the same symptom:

We saw this error when we updated the project from .net 4.7.1 to 4.7.2.

The problem was that even though we were not referencing System.Net.Http any more in the project, it was listed in the dependentAssembily section of our web.config. Removing this and any other unused assembly references from the web.config solved the problem.

Try to use the latest com.fasterxml.jackson.core/jackson-databind. I upgraded it to 2.9.4 and it works now.

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.4</version>
</dependency>

If you need to break based on the value of elements that are already in your array as in your case (i.e. if break condition does not depend on run-time variable that may change after array is assigned its element values) you could also use combination of slice() and indexOf() as follows.

If you need to break when forEach reaches 'Apple' you can use

var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];
var fruitsToLoop = fruits.slice(0, fruits.indexOf("Apple"));
// fruitsToLoop = Banana,Orange,Lemon

fruitsToLoop.forEach(function(el) {
    // no need to break
});

As stated in W3Schools.com the slice() method returns the selected elements in an array, as a new array object. The original array will not be changed.

See it in JSFiddle

Hope it helps someone.

One more option is require-dir-all combining features from most popular packages.

Most popular require-dir does not have options to filter the files/dirs and does not have map function (see below), but uses small trick to find module's current path.

Second by popularity require-all has regexp filtering and preprocessing, but lacks relative path, so you need to use __dirname (this has pros and contras) like:

var libs = require('require-all')(__dirname + '/lib');

Mentioned here require-index is quite minimalistic.

With map you may do some preprocessing, like create objects and pass config values (assuming modules below exports constructors):

// Store config for each module in config object properties 
// with property names corresponding to module names 
var config = {
  module1: { value: 'config1' },
  module2: { value: 'config2' }
};

// Require all files in modules subdirectory 
var modules = require('require-dir-all')(
  'modules', // Directory to require 
  { // Options 
    // function to be post-processed over exported object for each require'd module 
    map: function(reqModule) {
      // create new object with corresponding config passed to constructor 
      reqModule.exports = new reqModule.exports( config[reqModule.name] );
    }
  }
);

// Now `modules` object holds not exported constructors, 
// but objects constructed using values provided in `config`.
