You can use StrCSS as well, it creates isolated classnames and much more! Example code would look like. You can (optional) install the VSCode extension from the Visual Studio Marketplace for syntax highlighting support!

source: strcss

import { Sheet } from "strcss";
import React, { Component } from "react";

const sheet = new Sheet(`
  map button
    color green
    color red !ios
    fontSize 16
  on hover
    opacity .5
  at mobile
    fontSize 10
`);

export class User extends Component {
  render() {
    return <div className={sheet.map.button}>
      {"Look mom, I'm green!
      Unless you're on iOS..."}
    </div>;
  }
}

or you can simply try this in inline css

<textarea style="::placeholder{color:white}"/>

You can use the data in inline

 <style>   
 td { text-align: justify; }
 td:after { content: attr(data-content); display: inline-block; width: 100%; }
</style>

<table><tr><td data-content="post"></td></tr></table>

I agree with shadow. You could use the onmouseover and onmouseout event to change the CSS via JavaScript.

And don't say people need to have JavaScript activated. It's only a style issue, so it doesn't matter if there are some visitors without JavaScript ;) Although most of Web 2.0 works with JavaScript. See Facebook for example (lots of JavaScript) or Myspace.

it makes the assignment visible to subprocesses.

$ foo=bar
$ bash -c 'echo $foo'

$ export foo
$ bash -c 'echo $foo'
bar

You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()).

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        if (game != 1) {
            requestAnimFrame(loop);
        }
    }
}

Or alternatively you could simply skip the second if condition and change the first condition to if (isPlaying && game !== 1). You would have to make a variable called game and give it a value of 0. Add 1 to it every game.

Yes, in my perspective there is no reason why you should write your own. Most of the Open Source BPM/Workflow frameworks are extremely flexible, you just need to learn the basics. If you choose jBPM you will get much more than a simple workflow engine, so it depends what are you trying to build.

from os.path import dirname, realpath, join

Update:

If you happen to "copy" settings.py through symlinking, @forivall's answer is better:

~user/
    project1/  
        mysite/
            settings.py
        templates/
            wrong.html

    project2/
        mysite/
            settings.py -> ~user/project1/settings.py
        templates/
            right.html

The method above will 'see' wrong.html while @forivall's method will see right.html

In the absense of symlinks the two answers are identical.

TLDR; technically space sorts before exclamation mar, and can be used by preceding it with ' or - (which will be ignored in sorting), but exclamation mark follows right after space, and is easier to use.

On windows 7 at least, a minus sign (-) and (') seem to be ignored in a name except for one quirk: in a name that is otherwise identical, the ' will be sorted before -, for example: (a'a) will sort above (a-a)

Empty string will sort above everything else, which means for example aa will sort above aaa because the 'empty string' after two a letters will sort before the third 'a'.

This also means that aa will be sorted above a'a because the 'empty string' between two a letters will sort above the ' mark.

What follows then is, ' alone will sort first, because technically it's an empty string. However adding for example letters behind it will sort the name as if the ' didn't exist.

Since the first 'unignored' character (as far as I know) is space, in case you want to sort 'real names' above others, the best way to go would be ' followed by space, and then the name you want to actually use. For example: (' first)

You can of course top that by using more than one space in the strong, such as (' firster) and (' firstest) with two and three blanks before the f.

While minus sign sorts below ' in otherwise similar name, there's no other difference in sorting (that I know of), and I find minus sign visually clearer, so if I want to put something on top of list, I'd use minus followed by space, then the 'actual name', for example: (- first file -)

If you are worried about using space on the filename, then exclamation mark (!) is the next best thing - and since it can appear as first character on a string, it's easier to use.

Try something like this:

DECLARE @userData TABLE(
    name varchar(30) NOT NULL,
    oldlocation varchar(30) NOT NULL
);

INSERT INTO @userData (name, oldlocation)
SELECT name, location FROM myTable
INNER JOIN otherTable ON ...
WHERE age > 30;

This function will clear the sheet data starting from specified row and column :

Sub ClearWKSData(wksCur As Worksheet, iFirstRow As Integer, iFirstCol As Integer)

Dim iUsedCols As Integer
Dim iUsedRows As Integer

iUsedRows = wksCur.UsedRange.Row + wksCur.UsedRange.Rows.Count - 1
iUsedCols = wksCur.UsedRange.Column + wksCur.UsedRange.Columns.Count - 1

If iUsedRows > iFirstRow And iUsedCols > iFirstCol Then
    wksCur.Range(wksCur.Cells(iFirstRow, iFirstCol), wksCur.Cells(iUsedRows, iUsedCols)).Clear
End If

End Sub

It usually happen when your have included the dependency and it won't have repository reference like mavenCentral() or jcenter() etc to download it

What I usually do identify such dependency is set gradle to work offline, Android studio will automatically show a dependency which is not locally available, then look for the dependency details in their providers github page like from which repository to pick from and update your repositories and sink it. Hope it will work

Use the below command to get the first row from a CSV file or any file formats.

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

I haven't done this in a while, but I had to go through this same thing once.

<img src="about:blank" alt="" />

Anyways, the rendering of about:blank is actually very fast in all browsers that I tested. I just threw it into the W3C validator and it didn't complain, so it might even be valid.

Edit: Don't do that; it doesn't work on all browsers (it will show a 'broken image' icon as pointed out in the comments for this answer). Use the <img src='data:... solution below. Or if you don't care about validity, but still want to avoid superfluous requests to your server, you can do <img alt="" /> with no src attribute. But that is INVALID HTML so pick that carefully.

Test Page showing a whole bunch of different methods: http://desk.nu/blank_image.php - served with all kinds of different doctypes and content-types. - as mentioned in the comments below, use Mark Ormston's new test page at: http://memso.com/Test/BlankImage.html

The same problem happened to me using PostgreSQL I cleared all migrations in migrations folder and in migrations cache folder, and then in my PGADMIN ran:

delete from django_migrations where app='your_app'

You should use $.map for this:

var array = ["one", "two", "three"];

var el = $.map(array, function(val, i) {
  return "<span>" + val + "</span>";
});

$(".element").html(el.join(""));

Simply restate the target field & condition;

where (field like "*AA*" and field not like "*BB*")

There is build in forEach loop for array in ECMAScript 5th Edition.

var buttons = document.getElementsByClassName("navButton");

Array.prototype.forEach.call(buttons,function(button) { 
    button.setAttribute("class", "active");
    button.setAttribute("src", "images/arrows/top_o.png"); 
});

This solution is working with MySQL 5.0
Create a table - mytable.
The schema does not material. What matters is the number of rows in it.
So, you can keep just one column of type INT with 10 rows, values - 1 to 10.

SQL:

set @tempDate=date('2011-07-01') - interval 1 day;
select
date(@tempDate := (date(@tempDate) + interval 1 day)) as theDate
from mytable x,mytable y
group by theDate
having theDate <= '2011-07-31';

Limitation: The maximum number of dates returned by above query will be
(rows in mytable)*(rows in mytable) = 10*10 = 100.

You can increase this range by changing form part in sql:
from mytable x,mytable y, mytable z
So, the range be 10*10*10 =1000 and so on.

Just write:

private static double balance = 0;

and you could also write those like that:

private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

Add a tabIndex attribute to the body:

<body tabIndex=0 >

This is the only solution that also works when Javascript is disabled.

Add ontouchmove to the html element:

<html lang=en ontouchmove >

For examples and remarks see this blogpost:

Confirmed on iOS 13.

These solutions have the advantage that the hovered state disappears when you click somewhere else. Also no extra code needed in the source.

To limit what you run as sudo, you could run

python non_sudo_stuff.py
sudo -E python -c "import os; os.system('sudo echo 1')"

without needing to store the password. The -E parameter passes your current user's env to the process. Note that your shell will have sudo priveleges after the second command, so use with caution!

You can use openopt package and its NLP method. It has many dynamic programming algorithms to solve nonlinear algebraic equations consisting:
goldenSection, scipy_fminbound, scipy_bfgs, scipy_cg, scipy_ncg, amsg2p, scipy_lbfgsb, scipy_tnc, bobyqa, ralg, ipopt, scipy_slsqp, scipy_cobyla, lincher, algencan, which you can choose from.
Some of the latter algorithms can solve constrained nonlinear programming problem. So, you can introduce your system of equations to openopt.NLP() with a function like this:

lambda x: x[0] + x[1]**2 - 4, np.exp(x[0]) + x[0]*x[1]

HTML:

<div class="bool-answer">
  <div class="answer">Nej</div>
</div>

CSS:

.bool-answer {
    border-radius: 50%;
    width: 100px;
    height: 100px;
    display: flex;
    justify-content: center;
    align-items: center;
}

From bash 4.0 onward, you can use Brace Expansion with fixed length strings. See below for the original announcement.

It will do just what you need, and does not require anything external to the shell.

$ echo {01..05}
01 02 03 04 05

for num in {01..05}
do
  echo $num
done
01
02
03
04
05

CHANGES, release bash-4.0, section 3

This is a terse description of the new features added to bash-4.0 since the release of bash-3.2.

. . .

z. Brace expansion now allows zero-padding of expanded numeric values and will add the proper number of zeroes to make sure all values contain the same number of digits.

It took me a little while but finally figured out. Custom xpath that contains some text below worked perfectly for me.

//a[contains(text(),'JB-')]

Use field state $touched The field has been touched for this as shown in below example.

<div ng-show="formName.firstName.$touched && formName.firstName.$error.required">
    You must enter a value
</div>

Thank you. I believe that a complete example could be good for anyone else who have the same issue:

import pandas as pd
import numpy as np

path = r"C:\Users\fedel\Desktop\excelData\PhD_data.xlsx"

x1 = np.random.randn(100, 2)
df1 = pd.DataFrame(x1)

x2 = np.random.randn(100, 2)
df2 = pd.DataFrame(x2)

writer = pd.ExcelWriter(path, engine = 'xlsxwriter')
df1.to_excel(writer, sheet_name = 'x1')
df2.to_excel(writer, sheet_name = 'x2')
writer.save()
writer.close()

Here I generate an excel file, from my understanding it does not really matter whether it is generated via the "xslxwriter" or the "openpyxl" engine.

When I want to write without loosing the original data then

import pandas as pd
import numpy as np
from openpyxl import load_workbook

path = r"C:\Users\fedel\Desktop\excelData\PhD_data.xlsx"

book = load_workbook(path)
writer = pd.ExcelWriter(path, engine = 'openpyxl')
writer.book = book

x3 = np.random.randn(100, 2)
df3 = pd.DataFrame(x3)

x4 = np.random.randn(100, 2)
df4 = pd.DataFrame(x4)

df3.to_excel(writer, sheet_name = 'x3')
df4.to_excel(writer, sheet_name = 'x4')
writer.save()
writer.close()

this code do the job!

Not quite an answer (not “using Developer Tools”), but there is a third-party tool for it: IECookiesView from NirSoft. Hope this helps someone.

This will happen before ReactDOM.render() takes control of the root <div>. I.e. your App will not have been mounted up to that point.

So you can add your loader in your index.html file inside the root <div>. And that will be visible on the screen until React takes over.

You can use whatever loader element works best for you (svg with animation for example).

You don't need to remove it on any lifecycle method. React will replace any children of its root <div> with your rendered <App/>, as we can see in the GIF below.

Example on CodeSandbox

index.html

<head>
  <style>
    .svgLoader {
      animation: spin 0.5s linear infinite;
      margin: auto;
    }
    .divLoader {
      width: 100vw;
      height: 100vh;
      display: flex;
      align-items: center;
      justify-content: center;
    }
    @keyframes spin {
      0% { transform: rotate(0deg); }
      100% { transform: rotate(360deg); }
    }
  </style>
</head>

<body>
  <div id="root">
    <div class="divLoader">
      <svg class="svgLoader" viewBox="0 0 1024 1024" width="10em" height="10em">
        <path fill="lightblue"
          d="PATH FOR THE LOADER ICON"
        />
      </svg>
    </div>
  </div>
</body>

js-xlsx library makes it easy to convert Excel/CSV files into JSON objects.

Download the xlsx.full.min.js file from here. Write below code on your HTML page Edit the referenced js file link (xlsx.full.min.js) and link of Excel file

<!doctype html>
<html>

<head>
    <title>Excel to JSON Demo</title>
    <script src="xlsx.full.min.js"></script>

            var arraybuffer = oReq.response;

            /* convert data to binary string */
            var data = new Uint8Array(arraybuffer);
            var arr = new Array();
            for (var i = 0; i != data.length; ++i) arr[i] = String.fromCharCode(data[i]);
            var bstr = arr.join("");

            var worksheet = workbook.Sheets[first_sheet_name];
            console.log(XLSX.utils.sheet_to_json(worksheet, {
                raw: true

Nice question and comments - learnt much from the replies here :)

As an additional example, note that you can also mix body and routes e.g.

[RoutePrefix("api/test")]
public class MyProtectedController 
{
    [Authorize]
    [Route("id/{id}")]
    public IEnumerable<object> Post(String id, [FromBody] JObject data)
    {
        /*
          id                                      = "123"
          data.GetValue("username").ToString()    = "user1"
          data.GetValue("password").ToString()    = "pass1"
         */
    }
}

Calling like this:

POST /api/test/id/123 HTTP/1.1
Host: localhost
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer x.y.z
Cache-Control: no-cache

username=user1&password=pass1


enter code here

Try this. If a.b is undefined, it will leave the if statement without any exception.

if (a.b && a.b.c) {
  console.log(a.b.c);
}

This works for me across all browsers greater than version 6 (IE7, 8, 9, 10, etc, Chrome 3 up to what it is now, and FF ver 3 up to what it is now):

//test if running in IE or not
        function isIE () {
            var myNav = navigator.userAgent.toLowerCase();
            return (myNav.indexOf('msie') != -1 || myNav.indexOf('trident') != -1) ? true : false;
        }

Please note that newer versions of MPL have a shortcut for this task. An example is shown in the other answer to this question: https://stackoverflow.com/a/11386056/42346

The code below is for illustrative purposes and may not necessarily be optimized.

    y1 = np.cos(x)
    y2 = (x**2)
    y3 = (x**3)
    yn = (y1,y2,y3)
    COLORS = ('b','g','k')

    for i,y in enumerate(yn):
        ax = fig.add_subplot(len(yn),1,i+1)

        ax.plot(x, y, ls='solid', color=COLORS[i])

I finally went for a similar solution to the one that Sascha provided, however with some little adjusting, since I'm setting the cookies explicitly in PHP:

// excecute this code if user has not authorized the application yet
// $facebook object must have been created before

$accessToken = $_COOKIE['access_token']

if ( empty($accessToken) && strpos($_SERVER['HTTP_USER_AGENT'], 'Safari') ) {

    $accessToken = $facebook->getAccessToken();
    $redirectUri = 'https://URL_WHERE_APP_IS_LOCATED?access_token=' . $accessToken;

} else {

    $redirectUri = 'https://apps.facebook.com/APP_NAMESPACE/';

}

// generate link to auth dialog
$linkToOauthDialog = $facebook->getLoginUrl(
    array(
        'scope'         =>  SCOPE_PARAMS,
        'redirect_uri'  =>  $redirectUri
    )
);

echo '<script>window.top.location.href="' . $linkToOauthDialog . '";</script>';

What this does is check if the cookie is available when the browser is safari. In the next step, we are on the application domain, namely the URI provided as URL_WHERE_APP_IS_LOCATED above.

if (isset($_GET['accessToken'])) {

    // cookie has a lifetime of only 10 seconds, so that after
    // authorization it will disappear
    setcookie("access_token", $_GET['accessToken'], 10); 

} else {

  // depending on your application specific requirements
  // redirect, call or execute authorization code again
  // with the cookie now set, this should return FB Graph results

}

So after being redirecting to the application domain, a cookie is set explicitly, and I redirect the user to the authorization process.

In my case (since I'm using CakePHP but it should work fine with any other MVC framework) I'm calling the login action again where the FB authorization is executed another time, and this time it succeeds due to the existing cookie.

After having authorized the app once, I didn't have any more problems using the app with Safari (5.1.6)

Hope that might help anyone.

Notwithstanding the advice not to modify Object.prototype, this can still be really useful for testing, within a limited scope. The author of the accepted answer changed it, but is still setting Object.id, which doesn't make sense to me. Here's a snippet that does the job:

// Generates a unique, read-only id for an object.
// The _uid is generated for the object the first time it's accessed.

(function() {
  var id = 0;
  Object.defineProperty(Object.prototype, '_uid', {
    // The prototype getter sets up a property on the instance. Because
    // the new instance-prop masks this one, we know this will only ever
    // be called at most once for any given object.
    get: function () {
      Object.defineProperty(this, '_uid', {
        value: id++,
        writable: false,
        enumerable: false,
      });
      return this._uid;
    },
    enumerable: false,
  });
})();

function assert(p) { if (!p) throw Error('Not!'); }
var obj = {};
assert(obj._uid == 0);
assert({}._uid == 1);
assert([]._uid == 2);
assert(obj._uid == 0);  // still

If you want to $broadcast use the $rootScope:

$scope.startScanner = function() {

    $rootScope.$broadcast('scanner-started');
}

And then to receive, use the $scope of your controller:

$scope.$on('scanner-started', function(event, args) {

    // do what you want to do
});

If you want you can pass arguments when you $broadcast:

$rootScope.$broadcast('scanner-started', { any: {} });

And then receive them:

$scope.$on('scanner-started', function(event, args) {

    var anyThing = args.any;
    // do what you want to do
});

I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

GitHub here https://github.com/DukeOfMarshall/PHP---JSON-Email-Verification/tree/master

<?php

# What to do if the class is being called directly and not being included in a script     via PHP
# This allows the class/script to be called via other methods like JavaScript

if($_GET['address_to_verify'] == '' || !isset($_GET['address_to_verify'])){
    $return_array['error']              = 1;
    $return_array['message']            = 'No email address was submitted for verification';
    $return_array['domain_verified']    = 0;
    $return_array['format_verified']    = 0;
}else{
    $verify = new EmailVerify();

    if($verify->verify_formatting($_GET['address_to_verify'])){

As others have suggested, you could use the following:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';   # 'foo \1 bar' is an error.
my $var = "start middle end";
$var =~ s/$find/$replace/ee;

The above is short for the following:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
$var =~ s/$find/ eval($replace) /e;

I prefer the second to the first since it doesn't hide the fact that eval(EXPR) is used. However, both of the above silence errors, so the following would be better:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
$var =~ s/$find/ my $r = eval($replace); die $@ if $@; $r /e;

But as you can see, all of the above allow for the execution of arbitrary Perl code. The following would be far safer:

use String::Substitution qw( sub_modify );

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
sub_modify($var, $find, $replace);

what about such a MultiMap impl?

public class MultiMap<K, V> extends HashMap<K, Set<V>> {
  private static final long serialVersionUID = 1L;
  private Map<K, Set<V>> innerMap = new HashMap<>();

  public Set<V> put(K key, V value) {
    Set<V> valuesOld = this.innerMap.get(key);
    HashSet<V> valuesNewTotal = new HashSet<>();
    if (valuesOld != null) {
      valuesNewTotal.addAll(valuesOld);
    }
    valuesNewTotal.add(value);
    this.innerMap.put(key, valuesNewTotal);
    return valuesOld;
  }

  public void putAll(K key, Set<V> values) {
    for (V value : values) {
      put(key, value);
    }
  }

  @Override
  public Set<V> put(K key, Set<V> value) {
    Set<V> valuesOld = this.innerMap.get(key);
    putAll(key, value);
    return valuesOld;
  }

  @Override
  public void putAll(Map<? extends K, ? extends Set<V>> mapOfValues) {
    for (Map.Entry<? extends K, ? extends Set<V>> valueEntry : mapOfValues.entrySet()) {
      K key = valueEntry.getKey();
      Set<V> value = valueEntry.getValue();
      putAll(key, value);
    }
  }

  @Override
  public Set<V> putIfAbsent(K key, Set<V> value) {
    Set<V> valueOld = this.innerMap.get(key);
    if (valueOld == null) {
      putAll(key, value);
    }
    return valueOld;
  }

  @Override
  public Set<V> get(Object key) {
    return this.innerMap.get(key);
  }

  @Override
  etc. etc. override all public methods size(), clear() .....

}

You can use some JavaScript methods like below

1. self.location="http://www.example.com/index.php";

2. window.location.href="http://www.example.com/index.php";

3. document.location.href = 'http://www.example.com/index.php';

4. window.location.replace("http://www.example.com/index.php");

For a API v3 solution, refer to:

http://blog.enbake.com/draw-circle-with-google-maps-api-v3

It creates circle around points and then show markers within and out of the range with different colors. They also calculate dynamic radius but in your case radius is fixed so may be less work.

In PHP DateTime (PHP >= 5.3)

$dt = new DateTime();
$dt->setTimezone(new DateTimeZone('UTC'));
echo $dt->getTimestamp();

This is based on Jim's answer,

SELECT
    @field_text + SPACE(@pad_length - LEN(@field_text)) AS RightPad
   ,SPACE(@pad_length - LEN(@field_text)) + @field_text AS LeftPad

Advantages

• More Straight Forward
• Slightly Cleaner (IMO)
• Faster (Maybe?)
• Easily Modified to either double pad for displaying in non-fixed width fonts or split padding left and right to center

Disadvantages

• Doesn't handle LEN(@field_text) > @pad_length

You can use git submodule status or optionally git submodule status --recursive if you want to show nested submodules.

From the Git documentation:

Show the status of the submodules. This will print the SHA-1 of the currently checked out commit for each submodule, along with the submodule path and the output of git describe for the SHA-1. Each SHA-1 will be prefixed with - if the submodule is not initialized, + if the currently checked out submodule commit does not match the SHA-1 found in the index of the containing repository and U if the submodule has merge conflicts.

A solution where the logo is truly centered and the links are justified.

The max recommended number of links for the nav is 6, depending on the length of the words in eache link.

If you have 5 links, insert an empty link and style it with:

class="hidden-xs" style="visibility: hidden;"

in this way the number of links is always even.

You may find likr

$('.class').find('tag').attr('src');

Try with your IP Address , I think you can access it by internet.

Differences might not be meaningful in a typical use case, but using the standard DOM functionality

$("#el")[0].outerHTML

is about twice as fast as

$("<div />").append($("#el").clone()).html();

so I would go with:

/* 
 * Return outerHTML for the first element in a jQuery object,
 * or an empty string if the jQuery object is empty;  
 */
jQuery.fn.outerHTML = function() {
   return (this[0]) ? this[0].outerHTML : '';  
};

Center x = x + 1/2 of width

Center y = y + 1/2 of height 

If you know the width and height already then you only need one set of coordinates.

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

If you are using chosen, a jquery plugin, then to refresh or clear the content of the dropdown use:

$('#dropdown_id').empty().append($('< option>'))

dropdown_id.chosen().trigger("chosen:updated")

chosen:updated event will re-build itself based on the updated content.

As I don't like using putty in Windows as a workaround, I created a very simple utility ssh-agent-wrapper. It scans your .ssh folders and adds all your keys to the agent. You simply need to put it into Windows startup folder for it to work.

Assumptions:

• ssh-agent in path
• shh-add in path (both by choosing the "RED" option when installing git
• private keys are in %USERPROFILE%/.ssh folder
• private keys names start with id (e.g. id_rsa)

UsedRange represents not only nonempty cells, but also formatted cells without any value. And that's why you should be very vigilant.

Alternate syntax,

git fetch origin remote_branch_name:local_branch_name

since basestring isn't defined in Python3, this little trick might help to make the code compatible:

try: # check whether python knows about 'basestring'
   basestring
except NameError: # no, it doesn't (it's Python3); use 'str' instead
   basestring=str

after that you can run the following test on both Python2 and Python3

isinstance(myvar, basestring)

Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).

I think you are converting the data a bit more than you need to. Once you create the buffer with the proper encoding, you just need to write the buffer to the file.

var base64Data = req.rawBody.replace(/^data:image\/png;base64,/, "");

require("fs").writeFile("out.png", base64Data, 'base64', function(err) {
  console.log(err);
});

new Buffer(..., 'base64') will convert the input string to a Buffer, which is just an array of bytes, by interpreting the input as a base64 encoded string. Then you can just write that byte array to the file.

Update

As mentioned in the comments, req.rawBody is no longer a thing. If you are using express/connect then you should use the bodyParser() middleware and use req.body, and if you are doing this using standard Node then you need to aggregate the incoming data event Buffer objects and do this image data parsing in the end callback.

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

You can check out libvideo. It's much more up-to-date than YoutubeExtractor, and is fast and clean to use.

You can use assertThrows(), which allows you to test multiple exceptions within the same test. With support for lambdas in Java 8, this is the canonical way to test for exceptions in JUnit.

Per the JUnit docs:

import static org.junit.jupiter.api.Assertions.assertThrows;

@Test
void exceptionTesting() {
    MyException thrown = assertThrows(
           MyException.class,
           () -> myObject.doThing(),
           "Expected doThing() to throw, but it didn't"
    );

    assertTrue(thrown.getMessage().contains("Stuff"));
}

Python 2.X

There is a unicode-csv library which should solve your problems, with added benefit of not naving to write any new csv-related code.

Here is a example from their readme:

>>> import unicodecsv
>>> from cStringIO import StringIO
>>> f = StringIO()
>>> w = unicodecsv.writer(f, encoding='utf-8')
>>> w.writerow((u'é', u'ñ'))
>>> f.seek(0)
>>> r = unicodecsv.reader(f, encoding='utf-8')
>>> row = r.next()
>>> print row[0], row[1]
é ñ

Python 3.X

In python 3 this is supported out of the box by the build-in csv module. See this example:

import csv
with open('some.csv', newline='', encoding='utf-8') as f:
    reader = csv.reader(f)
    for row in reader:
        print(row)

Try svn revert filename for every file you don't need and haven't yet committed. Or alternatively do svn revert -R folder for the problematic folder and then re-do the operation with correct ignoring configuration.

From the documentation:

 you can undo any scheduling operations:

$ svn add mistake.txt whoops
A         mistake.txt
A         whoops
A         whoops/oopsie.c

$ svn revert mistake.txt whoops
Reverted mistake.txt
Reverted whoops

I had this or a similar problem after installing Tomcat.

The other answers didn't quite work, but got me on the right path. I answered this at https://stackoverflow.com/a/20762179/3128838 after discovering a YouTube video showing the exact problem I was having.

Your case is an extreme one, but here is a solution for others that fits a more common scenario of wanting to style fewer than 4 borders exactly the same.

border: 1px dashed red; border-width: 1px 1px 0 1px;

that is a little shorter, and maybe easier to read than

border-top: 1px dashed red;  border-right: 1px dashed red; border-left: 1px dashed red;

or

border-color: red; border-style: dashed; border-width: 1px 1px 0 1px;

In angular 4+ we can use innerHTML property instead of ng-bind-html.

In my case, it's working and I am using angular 5.

<div class="chart-body" [innerHTML]="htmlContent"></div>

In.ts file

let htmlContent = 'This is the `<b>Bold</b>` text.';

This might give you a good insight

ConcurrentHashMap achieves higher concurrency by slightly relaxing the promises it makes to callers. A retrieval operation will return the value inserted by the most recent completed insert operation, and may also return a value added by an insertion operation that is concurrently in progress (but in no case will it return a nonsense result). Iterators returned by ConcurrentHashMap.iterator() will return each element once at most and will not ever throw ConcurrentModificationException, but may or may not reflect insertions or removals that occurred since the iterator was constructed. No table-wide locking is needed (or even possible) to provide thread-safety when iterating the collection. ConcurrentHashMap may be used as a replacement for synchronizedMap or Hashtable in any application that does not rely on the ability to lock the entire table to prevent updates.

Regarding this:

However, iterators are designed to be used by only one thread at a time.

It means, while using iterators produced by ConcurrentHashMap in two threads are safe, it may cause an unexpected result in the application.

This is kind of a philosophical question (which perhaps only Microsoft can truly answer), since it's doing exactly what the documentation says.

System.IO.Path.Combine

"If path2 contains an absolute path, this method returns path2."

Here's the actual Combine method from the .NET source. You can see that it calls CombineNoChecks, which then calls IsPathRooted on path2 and returns that path if so:

public static String Combine(String path1, String path2) {
    if (path1==null || path2==null)
        throw new ArgumentNullException((path1==null) ? "path1" : "path2");
    Contract.EndContractBlock();
    CheckInvalidPathChars(path1);
    CheckInvalidPathChars(path2);

    return CombineNoChecks(path1, path2);
}

internal static string CombineNoChecks(string path1, string path2)
{
    if (path2.Length == 0)
        return path1;

    if (path1.Length == 0)
        return path2;

    if (IsPathRooted(path2))
        return path2;

    char ch = path1[path1.Length - 1];
    if (ch != DirectorySeparatorChar && ch != AltDirectorySeparatorChar &&
            ch != VolumeSeparatorChar) 
        return path1 + DirectorySeparatorCharAsString + path2;
    return path1 + path2;
}

I don't know what the rationale is. I guess the solution is to strip off (or Trim) DirectorySeparatorChar from the beginning of the second path; maybe write your own Combine method that does that and then calls Path.Combine().

With GNU Parallel you can do:

cat a.txt | parallel 'command1 {}; command2 {}; ...; '

There is this extensions that adds an event listener to attribute changes.

Usage:

<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<script type="text/javascript"
  src="https://cdn.rawgit.com/meetselva/attrchange/master/js/attrchange.js"></script>

Bind attrchange handler function to selected elements

$(selector).attrchange({
    trackValues: true, /* Default to false, if set to true the event object is 
                updated with old and new value.*/
    callback: function (event) { 
        //event               - event object
        //event.attributeName - Name of the attribute modified
        //event.oldValue      - Previous value of the modified attribute
        //event.newValue      - New value of the modified attribute
        //Triggered when the selected elements attribute is added/updated/removed
    }        
});

It will return the following format like

appending zero in start for the hours as well if it is less than 10

Here it is using ES6 syntax

const getTimeAMPMFormat = (date) => {
  let hours = date.getHours();
  let minutes = date.getMinutes();
  const ampm = hours >= 12 ? 'PM' : 'AM';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  hours = hours < 10 ? '0' + hours : hours;
  // appending zero in the start if hours less than 10
  minutes = minutes < 10 ? '0' + minutes : minutes;
  return hours + ':' + minutes + ' ' + ampm;
};
console.log(getTimeAMPMFormat(new Date)); // 09:59 AM

I know the devil is in the detail (especially where people's personal data is concerned), and that it would be very nice to have properly capitalised names, but the above kind of hassle is why the pragmatic, time-conscious amongst us use the following:

SELECT UPPER('Put YoUR O'So oddLy casED McWeird-nAme von rightHERE here')

In my experience, people are fine seeing THEIR NAME ... even when it's half way through a sentence.

Refer to: the Russians used a pencil!

All the answers that I can see here, including the currently "accepted" one, is actually wrong in that they set:

scrollTop = scrollHeight

Whereas the correct approach is to set:

scrollTop = scrollHeight - clientHeight

In other words:

$('#div1').scrollTop($('#div1')[0].scrollHeight - $('#div1')[0].clientHeight);

Or animated:

$("#div1").animate({
  scrollTop: $('#div1')[0].scrollHeight - $('#div1')[0].clientHeight
}, 1000);

QMessageBox includes static methods to quickly ask such questions:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    while (QMessageBox::question(nullptr,
                                 qApp->translate("my_app", "Test"),
                                 qApp->translate("my_app", "Are you sure you want to quit?"),
                                 QMessageBox::Yes|QMessageBox::No)
           != QMessageBox::Yes)
        // ask again
        ;
}

If your needs are more complex than provided for by the static methods, you should construct a new QMessageBox object, and call its exec() method to show it in its own event loop and obtain the pressed button identifier. For example, we might want to make "No" be the default answer:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)

You can easily pick image from asset without UIImage(named: "green-square-Retina").

Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.

See this Stackoverflow answer for reference.

Without FileReader, we can use URL.createObjectURL method to get the DOMString that represents the object ( our image file ).

Don't forget to validate image extension.

<input type="file" id="files" multiple />
<div class="image-preview"></div>

let file_input = document.querySelector('#files');
let image_preview = document.querySelector('.image-preview');

const handle_file_preview = (e) => {
  let files = e.target.files;
  let length = files.length;

  for(let i = 0; i < length; i++) {
      let image = document.createElement('img');
      // use the DOMstring for source
      image.src = window.URL.createObjectURL(files[i]);
      image_preview.appendChild(image);
  }
}

file_input.addEventListener('change', handle_file_preview);

Let me to recommend you a jQuery plugin for nice modal alers. It doesn't requires jquery UI.

Demo: http://www.webmasters.by/images/articles/jquery.alerts/index.html

Try using

for i in a :
  print(i[0])

i represents individual row in a.So,i[0] represnts the 1st element of each row.

And if you didn't want to use strict equality, you could use exists:

myFunction(strings.exists { x => customPredicate(x) })

I didn't see anyone answer this correctly. So I'm posting it here. In order to get columns to show up you need to specify the following line.

lvRegAnimals.View = View.Details;

And then add your columns after that.

lvRegAnimals.Columns.Add("Id", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);

Hope this helps anyone else looking for this answer in the future.

The two other answers given are for mkdir(1) and not mkdir(2) like you ask for, but you can look at the source code for that program and see how it implements the -p options which calls mkdir(2) repeatedly as needed.

Here is one more possible way using reshape:

a_norm = (a/a.sum(axis=1).reshape(-1,1)).round(3)
print(a_norm)

Or using None works too:

a_norm = (a/a.sum(axis=1)[:,None]).round(3)
print(a_norm)

Output:

array([[0.   , 0.333, 0.667],
       [0.25 , 0.333, 0.417],
       [0.286, 0.333, 0.381]])

Why not just

$(".commentArea").keypress(function(e) {
    var textVal = $(this).val();
    if(e.which == 13 && e.shiftKey) {

    }
    else if (e.which == 13) {
       e.preventDefault(); //Stops enter from creating a new line
       this.form.submit(); //or ajax submit
    }
});

its very true on oracle as well as sql is "users" is a reserved words just change it , it will serve u the best if u like change it to this

UPDATE system_info set field_value = 'NewValue' 

FROM system_users users JOIN system_info info ON users.role_type = info.field_desc where users.user_name = 'uname'

Trick about detect scroll up or down in listview, you just call this function on onScroll function in OnScrollListener of ListView.

private int oldFirstVisibleItem = -1;
    private protected int oldTop = -1;
    // you can change this value (pixel)
    private static final int MAX_SCROLL_DIFF = 5;

    private void calculateListScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        if (firstVisibleItem == oldFirstVisibleItem) {
            int top = view.getChildAt(0).getTop();
            // range between new top and old top must greater than MAX_SCROLL_DIFF
            if (top > oldTop && Math.abs(top - oldTop) > MAX_SCROLL_DIFF) {
                // scroll up
            } else if (top < oldTop && Math.abs(top - oldTop) > MAX_SCROLL_DIFF) {
                // scroll down
            }
            oldTop = top;
        } else {
            View child = view.getChildAt(0);
            if (child != null) {
                oldFirstVisibleItem = firstVisibleItem;
                oldTop = child.getTop();
            }
        }
    }

public static boolean stringToBool(String s) {
        s = s.toLowerCase();
        Set<String> trueSet = new HashSet<String>(Arrays.asList("1", "true", "yes"));
        Set<String> falseSet = new HashSet<String>(Arrays.asList("0", "false", "no"));

        if (trueSet.contains(s))
            return true;
        if (falseSet.contains(s))
            return false;

        throw new IllegalArgumentException(s + " is not a boolean.");
    }

My way to convert string to boolean.

you can receive the session id by issuing the following regular expression on document.cookie:

alert(document.cookie.match(/PHPSESSID=[^;]+/));

in my example the cookie name to store session id is PHPSESSID (php server), just replace the PHPSESSID with the cookie name that holds the session id. (configurable by the web server)

For a virtual function you need to provide implementation in the base class. However derived class can override this implementation with its own implementation. Normally , for pure virtual functions implementation is not provided. You can make a function pure virtual with =0 at the end of function declaration. Also, a class containing a pure virtual function is abstract i.e. you can not create a object of this class.

In my Windows 7 box I found netbeans.conf in <Drive>:\<Program Files folder>\<NetBeans installation folder>\etc . Thanks all.

Just to clarify a bit the difference between is and runtimeType. As someone said already (and this was tested with Dart V2+) the following code:

class Foo { 
  Type get runtimeType => String;
}
main() {
  var foo = new Foo();
  if (foo is Foo) {
    print("it's a foo!");
  }
  print("type is ${foo.runtimeType}");

}

will output:

it's a foo! 
type is String

Which is wrong. Now, I can't see the reason why one should do such a thing...

Change the number of rows in section to 1 You have changed number of sections instead number of rows

 func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        1
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return 2
    }

Here you put spacing between rows

 func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 50
    }

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

File uploading (most of this applies if sending plain text too if javascript can choose the name of the file) http://www.developershome.com/wap/wapUpload/wap_upload.asp?page=security https://www.owasp.org/index.php/Unrestricted_File_Upload

Here's an alternative solution without code. This VBA works in the Excel Formula Bar:

To extract the file name:

=RIGHT(A1,LEN(A1)-FIND("~",SUBSTITUTE(A1,"\","~",LEN(A1)-LEN(SUBSTITUTE(A1,"\","")))))

To extract the file path:

=MID(A1,1,LEN(A1)-LEN(MID(A1,FIND(CHAR(1),SUBSTITUTE(A1,"\",CHAR(1),LEN(A1)-LEN(SUBSTITUTE(A1,"\",""))))+1,LEN(A1))))

With .net 4 you could perhaps look at the ExpandoObject, however, don't use it for this simple case as what would have been compile-time errors become run-time errors.

class Program
{
    static void Main(string[] args)
    {
        dynamic employee, manager;

        employee = new ExpandoObject();
        employee.Name = "John Smith";
        employee.Age = 33;

        manager = new ExpandoObject();
        manager.Name = "Allison Brown";
        manager.Age = 42;
        manager.TeamSize = 10;

        WritePerson(manager);
        WritePerson(employee);
    }
    private static void WritePerson(dynamic person)
    {
        Console.WriteLine("{0} is {1} years old.",
                          person.Name, person.Age);
        // The following statement causes an exception
        // if you pass the employee object.
        // Console.WriteLine("Manages {0} people", person.TeamSize);
    }
}
// This code example produces the following output:
// John Smith is 33 years old.
// Allison Brown is 42 years old.

Something else worth mentioning is an anonymous type for within a method, but you need to create a class if you want to return it.

var MyStuff = new
    {
        PropertyName1 = 10,
        PropertyName2 = "string data",
        PropertyName3 = new ComplexType()
    };

Functions can be "passed" as function pointers, as per ISO C11 6.7.6.3p8: "A declaration of a parameter as ‘‘function returning type’’ shall be adjusted to ‘‘pointer to function returning type’’, as in 6.3.2.1. ". For example, this:

void foo(int bar(int, int));

is equivalent to this:

void foo(int (*bar)(int, int));

Postgres has a very rich system catalog exposed via SQL tables. PG's statistics collector is a subsystem that supports collection and reporting of information about server activity.

Now to figure out the blocking PIDs you can simply query pg_stat_activity.

select pg_blocking_pids(pid) as blocked_by
from pg_stat_activity
where cardinality(pg_blocking_pids(pid)) > 0;

To, get the query corresponding to the blocking PID, you can self-join or use it as a where clause in a subquery.

SELECT query
FROM pg_stat_activity
WHERE pid IN (select unnest(pg_blocking_pids(pid)) as blocked_by from pg_stat_activity where cardinality(pg_blocking_pids(pid)) > 0);

Note: Since pg_blocking_pids(pid) returns an Integer[], so you need to unnest it before you use it in a WHERE pid IN clause.

Hunting for slow queries can be tedious sometimes, so have patience. Happy hunting.

Use the (excellent) JSON-Java library from json.org then

JSONObject json = new JSONObject(str);
String xml = XML.toString(json);

toString can take a second argument to provide the name of the XML root node.

This library is also able to convert XML to JSON using XML.toJSONObject(java.lang.String string)

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

I also had need for this and I created the following extension method for it:

public static class RegexExtensions
{
    public static string ReplaceGroup(
        this Regex regex, string input, string groupName, string replacement)
    {
        return regex.Replace(
            input,
            m =>
            {
                var group = m.Groups[groupName];
                var sb = new StringBuilder();
                var previousCaptureEnd = 0;
                foreach (var capture in group.Captures.Cast<Capture>())
                {
                    var currentCaptureEnd =
                        capture.Index + capture.Length - m.Index;
                    var currentCaptureLength =
                        capture.Index - m.Index - previousCaptureEnd;
                    sb.Append(
                        m.Value.Substring(
                            previousCaptureEnd, currentCaptureLength));
                    sb.Append(replacement);
                    previousCaptureEnd = currentCaptureEnd;
                }
                sb.Append(m.Value.Substring(previousCaptureEnd));

                return sb.ToString();
            });
    }
}

Usage:

var input = @"[assembly: AssemblyFileVersion(""2.0.3.0"")][assembly: AssemblyFileVersion(""2.0.3.0"")]";
var regex = new Regex(@"AssemblyFileVersion\(""(?<version>(\d+\.?){4})""\)");


var result = regex.ReplaceGroup(input , "version", "1.2.3");

Result:

[assembly: AssemblyFileVersion("1.2.3")][assembly: AssemblyFileVersion("1.2.3")]

You can also just use the top command and your user ID will indicate the jobs running and the their times.

$ top

(this will show all running jobs)

$ top -U [user ID]

(This will show jobs that are specific for the user ID)

To replace na values in pandas

df['column_name'].fillna(value_to_be_replaced,inplace=True)

if inplace = False, instead of updating the df (dataframe) it will return the modified values.

You can use this little PHP library. It sends the headers and give you an object to use it easily.

It looks like :

<?php
// Include the json class
include('includes/json.php');

// Then create the PHP-Json Object to suits your needs

// Set a variable ; var name = {}
$Json = new json('var', 'name'); 
// Fire a callback ; callback({});
$Json = new json('callback', 'name'); 
// Just send a raw JSON ; {}
$Json = new json();

// Build data
$object = new stdClass();
$object->test = 'OK';
$arraytest = array('1','2','3');
$jsonOnly = '{"Hello" : "darling"}';

// Add some content
$Json->add('width', '565px');
$Json->add('You are logged IN');
$Json->add('An_Object', $object);
$Json->add("An_Array",$arraytest);
$Json->add("A_Json",$jsonOnly);

// Finally, send the JSON.

$Json->send();
?>

I'm leaving this answer for someone who gets in this scenario as I did.

I stumbled here and there before noticing that I mistakenly dragged and dropped the Support Library JAR file into my src folder and it was lying there. Since I had no idea how it happened or when I dropped it there, I could never imagine something was wrong there.

I was getting the same error, I found the problem after sometime and removed it. Project is now working fine.

Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.

Indexes are all about finding data quickly.

Indexes in a database are analogous to indexes that you find in a book. If a book has an index, and I ask you to find a chapter in that book, you can quickly find that with the help of the index. On the other hand, if the book does not have an index, you will have to spend more time looking for the chapter by looking at every page from the start to the end of the book.

In a similar fashion, indexes in a database can help queries find data quickly. If you are new to indexes, the following videos, can be very useful. In fact, I have learned a lot from them.

str = "aaaaabbbb"
newstr = str[-4:]

See : http://codepad.org/S3zjnKoD

String.contains(String) or String.indexOf(String) - suggested

"abc".contains("Z"); // false - correct
"zzzz".contains("Z"); // false - correct
"Z".contains("Z"); // true - correct
"and".contains(""); // true - correct
"and".contains(""); // false - correct
"and".indexOf(""); // 0 - correct
"and".indexOf(""); // -1 - correct

String.indexOf(int) and carefully considered String.indexOf(char) with char to int widening

"and".indexOf("".charAt(0)); // 0 though incorrect usage has correct output due to portion of correct data
"and".indexOf("".charAt(0)); // 0 -- incorrect usage and ambiguous result
"and".indexOf("".codePointAt(0)); // -1 -- correct usage and correct output

The discussions around character is ambiguous in Java world

can the value of char or Character considered as single character?

No. In the context of unicode characters, char or Character can sometimes be part of a single character and should not be treated as a complete single character logically.

if not, what should be considered as single character (logically)?

Any system supporting character encodings for Unicode characters should consider unicode's codepoint as single character.

So Java should do that very clear & loud rather than exposing too much of internal implementation details to users.

String class is bad at abstraction (though it requires confusingly good amount of understanding of its encapsulations to understand the abstraction and hence an anti-pattern).

How is it different from general char usage?

char can be only be mapped to a character in Basic Multilingual Plane.

Only codePoint - int can cover the complete range of Unicode characters.

Why is this difference?

char is internally treated as 16-bit unsigned value and could not represent all the unicode characters using UTF-16 internal representation using only 2-bytes. Sometimes, values in a 16-bit range have to be combined with another 16-bit value to correctly define character.

Without getting too verbose, the usage of indexOf, charAt, length and such methods should be more explicit. Sincerely hoping Java will add new UnicodeString and UnicodeCharacter classes with clearly defined abstractions.

Reason to prefer contains and not indexOf(int)

1. Practically there are many code flows that treat a logical character as char in java.
2. In Unicode context, char is not sufficient
3. Though the indexOf takes in an int, char to int conversion masks this from the user and user might do something like str.indexOf(someotherstr.charAt(0))(unless the user is aware of the exact context)
4. So, treating everything as CharSequence (aka String) is better

    public static void main(String[] args) {
        System.out.println("and".indexOf("".charAt(0))); // 0 though incorrect usage has correct output due to portion of correct data
        System.out.println("and".indexOf("".charAt(0))); // 0 -- incorrect usage and ambiguous result
        System.out.println("and".indexOf("".codePointAt(0))); // -1 -- correct usage and correct output
        System.out.println("and".contains("")); // true - correct
        System.out.println("and".contains("")); // false - correct
    }

Functional Interface:

• Introduced in Java 8
• Interface that contains a "single abstract" method.

Example 1:

   interface CalcArea {   // --functional interface
        double calcArea(double rad);
    }           

Example 2:

interface CalcGeometry { // --functional interface
    double calcArea(double rad);
    default double calcPeri(double rad) {
        return 0.0;
    }
}       

Example 3:

interface CalcGeometry {  // -- not functional interface
    double calcArea(double rad);
    double calcPeri(double rad);
}   

Java8 annotation -- @FunctionalInterface

• Annotation check that interface contains only one abstract method. If not, raise error.
• Even though @FunctionalInterface missing, it is still functional interface (if having single abstract method). The annotation helps avoid mistakes.
• Functional interface may have additional static & default methods.
• e.g. Iterable<>, Comparable<>, Comparator<>.

Applications of Functional Interface:

• Method references
• Lambda Expression
• Constructor references

To learn functional interfaces, learn first default methods in interface, and after learning functional interface, it will be easy to you to understand method reference and lambda expression

There are few steps if we dont use "create-react-app",([email protected]) first we should install file-loader as devDedepencie,next step is to add rule in webpack.config

{
    test: /\.(png|jpe?g|gif)$/i,
    loader: 'file-loader',
}

, then in our src directory we should make file called declarationFiles.d.ts(for example) and register modules inside

declare module '*.jpg';
declare module '*.png';

,then restart dev-server. After these steps we can import and use images like in code bellow

import React from 'react';
import image from './img1.png';
import './helloWorld.scss';

const HelloWorld = () => (
  <>
    <h1 className="main">React TypeScript Starter</h1>
        <img src={image} alt="some example image" />
  </>
);
export default HelloWorld;

Works in typescript and also in javacript,just change extension from .ts to .js

One Idea:

UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering, ordering), 
    title=ISNULL(@title, title),  
    content=ISNULL(@content, content)
WHERE id=@id

It's simple; An example is:

<input type="text" id="example"> // Setup text field 
<script type="text/javascript"> 
var elem = document.getElementById("example"); // Get text field
elem.value = "My default value"; // Change field
</script>

A couple of additional points re use of vector here.

Unlike ArrayList and Array in Java, you don't need to do anything special to treat a vector as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.

Unlike ArrayList, a vector can efficiently hold primitive types without encapsulation as a full-fledged object.

When removing items from a vector, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.

Make sure if you store complex objects in the vector that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.

Advice about reserve()ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.

I have been there, like so many of us. There are so many confusing words like Web API, REST, RESTful, HTTP, SOAP, WCF, Web Services... and many more around this topic. But I am going to give brief explanation of only those which you have asked.

REST

It is neither an API nor a framework. It is just an architectural concept. You can find more details here.

RESTful

I have not come across any formal definition of RESTful anywhere. I believe it is just another buzzword for APIs to say if they comply with REST specifications.

EDIT: There is another trending open source initiative OpenAPI Specification (OAS) (formerly known as Swagger) to standardise REST APIs.

Web API

It in an open source framework for writing HTTP APIs. These APIs can be RESTful or not. Most HTTP APIs we write are not RESTful. This framework implements HTTP protocol specification and hence you hear terms like URIs, request/response headers, caching, versioning, various content types(formats).

Note: I have not used the term Web Services deliberately because it is a confusing term to use. Some people use this as a generic concept, I preferred to call them HTTP APIs. There is an actual framework named 'Web Services' by Microsoft like Web API. However it implements another protocol called SOAP.

Yes, you can! There's a Visual Studio for macs and there's Visual Studio Code if you only need a text editor like Sublime Text.

That depends. Is it just a variable (in a method)? Or a class-member?

If it's just a variable you'll get an error that no value has been set when trying to read from it without first assinging it a value.

If it's a class-member it will be initialized to null by the VM.

Since it is your files in your app bundle, I think you can use pathForResource:ofType: to get the full pathname of your file.

Here is an example:

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"your_file_name" 
                                            ofType:@"the_file_extension"];

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

Yep, both and and or operators short-circuit -- see the docs.

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

Web Site = use when the website is created by graphic designers and the programmers only edit one or two pages

Web Application = use when the application is created by programmers and the graphic designers only edit one or two paged/images.

Web Sites can be worked on using any HTML tools without having to have developer studio, as project files don’t need to be updated, etc. Web applications are best when the team is mostly using developer studio and there is a high code content.

(Some coding errors are found in Web Applications at compile time that are not found in Web Sites until run time.)

Warning: I wrote this answer many years ago and have not used Asp.net since. I expect things have now moved on.

The dir wrapper can wrap, any other step, and it all works inside a steps block, for example:

steps {
    sh "pwd"
    dir('your-sub-directory') {
      sh "pwd"
    }
    sh "pwd"
} 

A List is an ordered Collection of elements. You can add them with the add method, and retrieve them with the get(int index) method. You can also iterate over a List, remove elements, etc. Here are some basic examples of using a List:

List<String> names = new ArrayList<String>(3); // 3 because we expect the list 
    // to have 3 entries.  If we didn't know how many entries we expected, we
    // could leave this empty or use a LinkedList instead
names.add("Alice");
names.add("Bob");
names.add("Charlie");
System.out.println(names.get(2)); // prints "Charlie"
System.out.println(names); // prints the whole list
for (String name: names) {
    System.out.println(name);  // prints the names in turn.
}

I think you have to use ::-wekbit-scrollbar for all the scrollbars, and you can use:

<style>
.mydiv {
height:100px;
overflow:auto;
}
     /* width */
    .mydiv::-webkit-scrollbar {
      width: 20px;
    }
    
    /* Track */
    .mydiv::-webkit-scrollbar-track {
      box-shadow: inset 0 0 5px grey; 
      border-radius: 10px;
    }
     
    /* Handle */
    .mydiv::-webkit-scrollbar-thumb {
      background: red;
      border-radius: 10px;
    }
    
    /* Handle on hover */
    .mydiv::-webkit-scrollbar-thumb:hover {
      background: #b30000; 
    }
</style>

I had this same problem installing SQL Server 2014. Turns out it was due to a Windows Phone toolkit that I had installed back in 2010. If you run into this, make sure you uninstall any Windows phone stuff that isn't current.

I figured it out by looking at the log, which can be found by clicking "Detailed Report," which opens an HTML file. The file path is conveniently displayed within the HTML page. Open the directory that the file is in and look for "Detail.txt." Then search for the word "fail."

In my case there was a line showing WP_[something] as "Installed." I searched for the WP_ item and came across some blog posts about trouble uninstalling Windows Phone toolkits.

When I attempted to uninstall the windows phone I ran into more trouble. The uninstaller wanted to install three packages instead of uninstalling the toolkit. Eventually found this blog post: http://blogs.msdn.com/b/astebner/archive/2010/07/12/10037442.aspx linking to this XNA cleanup tool: http://blogs.msdn.com/b/astebner/archive/2009/04/10/9544320.aspx.

I ran the cleanup tool and finally SQL Server installer passed the check and allowed me to install. Hope this helps someone.

Add checked to both of your radio button. And then show/hide your desired one on document ready.

When you are connecting to another machine over SSH, you can enable X-Forwarding in SSH, so that X windows are forwarded encrypted through the SSH tunnel back to your machine. You can enable X forwarding by appending -X to the ssh command line or setting ForwardX11 yes in your SSH config file.

To check if the X-Forwarding was set up successfully (the server might not allow it), just try if echo $DISPLAY outputs something like localhost:10.0.

I would do it this way, so you won't end up with duplicate entries if the script is run multiple times.

glOrtho describes a transformation that produces a parallel projection. The current matrix (see glMatrixMode) is multiplied by this matrix and the result replaces the current matrix, as if glMultMatrix were called with the following matrix as its argument:

OpenGL documentation (my bold)

The numbers define the locations of the clipping planes (left, right, bottom, top, near and far).

The "normal" projection is a perspective projection that provides the illusion of depth. Wikipedia defines a parallel projection as:

Parallel projections have lines of projection that are parallel both in reality and in the projection plane.

Parallel projection corresponds to a perspective projection with a hypothetical viewpoint—e.g., one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".

Only one route enough for this

config.Routes.MapHttpRoute("DefaultApiWithAction", "{controller}/{action}");

And need to specify attribute HttpGet or HttpPost in all actions.

[HttpGet]
public IEnumerable<object> TestGet1()
{
    return new string[] { "value1", "value2" };
}

[HttpGet]
public IEnumerable<object> TestGet2()
{
    return new string[] { "value3", "value4" };
}

document.getElementById('table1').rows[0].cells.length

cells is not a property of a table, rows are. Cells is a property of a row though

You can run the following, which will generate a set of ALTER sCHEMA statements for all your talbes:

SELECT 'ALTER SCHEMA dbo TRANSFER ' + TABLE_SCHEMA + '.' + TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'jonathan'

You then have to copy and run the statements in query analyzer.

Here's an older script that will do that for you, too, I think by changing the object owner. Haven't tried it on 2008, though.

DECLARE @old sysname, @new sysname, @sql varchar(1000)

SELECT
  @old = 'jonathan'
  , @new = 'dbo'
  , @sql = '
  IF EXISTS (SELECT NULL FROM INFORMATION_SCHEMA.TABLES
  WHERE
      QUOTENAME(TABLE_SCHEMA)+''.''+QUOTENAME(TABLE_NAME) = ''?''
      AND TABLE_SCHEMA = ''' + @old + '''
  )
  EXECUTE sp_changeobjectowner ''?'', ''' + @new + ''''

EXECUTE sp_MSforeachtable @sql

Got it from this site.

It also talks about doing the same for stored procs if you need to.

The nuget.exe utility doesn't have this feature, but seeing that the NuGet cache is simply a folder on your computer, you can delete the files manually. Just add this to your batch file:

del %LOCALAPPDATA%\NuGet\Cache\*.nupkg /q

The best way is, since you intend to bundle your modules together, you can specify <dependencyManagement> tag in outer most pom.xml (parent module) direct under <project> tag. It controls the version and group name. In your individual module, you just need to specify the <artifactId> tag in your pom.xml. It will take the version from parent file.

Here you go:

div{
    display: none;
}

document.querySelector("button").addEventListener("click", function(){
    document.querySelector("div").style.display = "block";
});

<div>blah blah blah</div>
<button>Show</button>

I had a similar question, but wasn't satisfied with the answer (or any I could find on the net), so I tried it in practice and here is what I got:

• init does not cause layoutSubviews to be called (duh)
• addSubview: causes layoutSubviews to be called on the view being added, the view it’s being added to (target view), and all the subviews of the target
• view setFrame intelligently calls layoutSubviews on the view having its frame set only if the size parameter of the frame is different
• scrolling a UIScrollView causes layoutSubviews to be called on the scrollView, and its superview
• rotating a device only calls layoutSubview on the parent view (the responding viewControllers primary view)
• Resizing a view will call layoutSubviews on its superview

My results - http://blog.logichigh.com/2011/03/16/when-does-layoutsubviews-get-called/

I was also facing this issue but in a little different scenario.

Scenario:

param = 1

def param():
    .....
def func():
    if param:
        var = {passing a dict here}
        param(var)

It looks simple and a stupid mistake here, but due to multiple lines of codes in the actual code, it took some time for me to figure out that the variable name I was using was same as my function name because of which I was getting this error.

Changed function name to something else and it worked.

So, basically, according to what I understood, this error means that you are trying to use an integer as a function or in more simple terms, the called function name is also used as an integer somewhere in the code. So, just try to find out all occurrences of the called function name and look if that is being used as an integer somewhere.

I struggled to find this, so, sharing it here so that someone else may save their time, in case if they get into this issue.

Hope this helps!

I have tried both the options suggested by Michael Munsey and works for me.

I am a little late but I used this:

dir /B *.* > dir_file.txt

then you can make a simple FOR loop to extract the file name and use them. e.g:

for /f "tokens=* delims= " %%a in (dir_file.txt) do (
gawk -f awk_script_file.awk %%a
)

or store them into Vars (!N1!, !N2!..!Nn!) for later use. e.g:

set /a N=0
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
set /a N+=1
set v[!N!]=%%a
)

If the installed "AccessDatabaseEngine" still does not help, below is solution:

For people using Xcode 11.4, to get rid of the simulator top bar, this is far from ideal but you can disable shadows for the screenshot application in a terminal with the following command :

$ defaults write com.apple.screencapture disable-shadow -bool TRUE; killall SystemUIServer

Then, you can use ? + ? + 4 and select the simulator to take a screenshot. Without the shadow, you can easily crop the top bar with the preview app. To re-enable the shadow for the screenshot application :

$ defaults write com.apple.screencapture disable-shadow -bool FALSE; killall SystemUIServer

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

In case you are on Mac OS (catalina or mojave) and wants to enable HTTPS/SSL on XAMPP for Mac, you need to enable the virtual host and use the default certificates included in XAMPP. On your httpd-vhosts.conf file add a new vhost:

<VirtualHost *:443>
    ServerAdmin [email protected]
    DocumentRoot "/Users/your-user/your-site"
    ServerName your-site.local
    SSLEngine on
    SSLCertificateFile "etc/ssl.crt/server.crt" 
    SSLCertificateKeyFile "etc/ssl.key/server.key"
    <Directory "/Users/your-user/your-site">
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

Since C++11 you could use std::put_time from iomanip header:

#include <iostream>
#include <iomanip>
#include <ctime>

int main()
{
    auto t = std::time(nullptr);
    auto tm = *std::localtime(&t);
    std::cout << std::put_time(&tm, "%d-%m-%Y %H-%M-%S") << std::endl;
}

std::put_time is a stream manipulator, therefore it could be used together with std::ostringstream in order to convert the date to a string:

#include <iostream>
#include <iomanip>
#include <ctime>
#include <sstream>

int main()
{
    auto t = std::time(nullptr);
    auto tm = *std::localtime(&t);

    std::ostringstream oss;
    oss << std::put_time(&tm, "%d-%m-%Y %H-%M-%S");
    auto str = oss.str();

    std::cout << str << std::endl;
}

This may help... use the following code and browse the folder you want to set as the working folder

You could try this if you have 3 dataframes

# Merge multiple dataframes

    columns=['name', 'attr11', 'attr12'])
df2 = pd.DataFrame(np.array([
    ['a', 5, 19],
    ['b', 14, 16],
    ['c', 4, 9]]),
    columns=['name', 'attr21', 'attr22'])
df3 = pd.DataFrame(np.array([
    ['a', 15, 49],
    ['b', 4, 36],
    ['c', 14, 9]]),
    columns=['name', 'attr31', 'attr32'])

pd.merge(pd.merge(df1,df2,on='name'),df3,on='name')

alternatively, as mentioned by cwharland

df1.merge(df2,on='name').merge(df3,on='name')

This is an old question, and the answers here seem to mostly advocate for using mousedown and mouseup to keep track of whether a button is pressed. But as others have pointed out, mouseup will only fire when performed within the browser, which can lead to losing track of the button state.

However, MouseEvent (now) indicates which buttons are currently pushed:

• For all modern browsers (except Safari) use MouseEvent.buttons
• For Safari, use MouseEvent.which (buttons will be undefined for Safari) Note: which uses different numbers from buttons for Right and Middle clicks.

When registered on document, mousemove will fire immediately as soon as the cursor reenters the browser, so if the user releases outside then the state will be updated as soon as they mouse back inside.

A simple implementation might look like:

var leftMouseButtonOnlyDown = false;

function setLeftButtonState(e) {
  leftMouseButtonOnlyDown = e.buttons === undefined 
    ? e.which === 1 
    : e.buttons === 1;
}

document.body.onmousedown = setLeftButtonState;
document.body.onmousemove = setLeftButtonState;
document.body.onmouseup = setLeftButtonState;

If more complicated scenarios are required (different buttons/multiple buttons/control keys), check out the MouseEvent docs. When/if Safari lifts its game, this should get easier.

I guess your entity_property has a composite key (entity_id, name) where entity_id is a foreign key to entity. If so, you can map it as follows:

@Embeddable
public class EntityPropertyPK {
    @Column(name = "name")
    private String name;

    @ManyToOne
    @JoinColumn(name = "entity_id")
    private Entity entity;

    ...
}

@Entity 
@Table(name="entity_property") 
public class EntityProperty { 
    @EmbeddedId
    private EntityPropertyPK id;

    @Column(name = "value")
    private String value; 

    ...
}

You couldn't login because you did't get proper solt text at login time. There are two options, first is define static salt, second is if you want create dynamic salt than you have to store the salt somewhere (means in database) with associate with user. Than you concatenate user solt+password_hash string now with this you fire query with username in your database table.

I created a function to generate a form, based on url, target and an object as the POST/GET data and submit method. It supports nested and mixed types within that object, so it can fully replicate any structure you feed it: PHP automatically parses it and returns it as a nested array. However, there is a single restriction: the brackets [ and ] must not be part of any key in the object (like {"this [key] is problematic" : "hello world"}). If someone knows how to escape it properly, please do tell!

Without further ado, here is the source:

You can do it without forcing html and body to me 100% height. Use view port height instead. And with mouse wheel control too.

These are much much better references than w3schools (the most awful web reference ever made):

• How cookies work (quirksmode.org)
• MDN document.cookie

Examples derived from these references:

// sets the cookie cookie1
document.cookie = 'cookie1=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// sets the cookie cookie2 (cookie1 is *not* overwritten)
document.cookie = 'cookie2=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// remove cookie2
document.cookie = 'cookie2=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/'

The Mozilla reference even has a nice cookie library you can use.

For me just running the below command is not enough (though a valid first step):

npm install -g typescript

The following command is what you need (I think deleting node_modules works too, but the below command is quicker)

npm link typescript

We could do it with jQuery:

$(window).resize(function(){
    alert(window.innerWidth);

    $scope.$apply(function(){
       //do something to update current scope based on the new innerWidth and let angular update the view.
    });
});

Be aware that when you bind an event handler inside scopes that could be recreated (like ng-repeat scopes, directive scopes,..), you should unbind your event handler when the scope is destroyed. If you don't do this, everytime when the scope is recreated (the controller is rerun), there will be 1 more handler added causing unexpected behavior and leaking.

In this case, you may need to identify your attached handler:

  $(window).on("resize.doResize", function (){
      alert(window.innerWidth);

      $scope.$apply(function(){
          //do something to update current scope based on the new innerWidth and let angular update the view.
      });
  });

  $scope.$on("$destroy",function (){
      $(window).off("resize.doResize"); //remove the handler added earlier
  });

In this example, I'm using event namespace from jQuery. You could do it differently according to your requirements.

Improvement: If your event handler takes a bit long time to process, to avoid the problem that the user may keep resizing the window, causing the event handlers to be run many times, we could consider throttling the function. If you use underscore, you can try:

$(window).on("resize.doResize", _.throttle(function (){
    alert(window.innerWidth);

    $scope.$apply(function(){
        //do something to update current scope based on the new innerWidth and let angular update the view.
    });
},100));

or debouncing the function:

$(window).on("resize.doResize", _.debounce(function (){
     alert(window.innerWidth);

     $scope.$apply(function(){
         //do something to update current scope based on the new innerWidth and let angular update the view.
     });
},100));

Difference Between throttling and debouncing a function

Here https://toddmotto.com/mastering-the-module-pattern you can find the pattern thoroughly explained. I would add that the second thing about modular JavaScript is how to structure your code in multiple files. Many folks may advice you here to go with AMD, yet I can say from experience that you will end up on some point with slow page response because of numerous HTTP requests. The way out is pre-compilation of your JavaScript modules (one per file) into a single file following CommonJS standard. Take a look at samples here http://dsheiko.github.io/cjsc/

Since the true Binding URL for the web service is located in the file, you could do these simple steps from your local machine:

1) Save the file to your local computer for example:

C:\Documents and Settings\[user]\Desktop\Webservice1.asmx

2) In Visual Studio Right Click on your project > Choose Add Web Reference, A dialog will open.

3) In the URL Box Copy the local file location above C:\Documents and Settings[user]\Desktop\Webservice1.asmx, Click Next

4) Now you will see the functions appear, choose your name for the reference, Click add reference

5) You are done! you can start using it as a namespace in your application don't worry that you used a local file, because anyway the true URL for the service is located in the file at the Binding section

I had existing data in the first column and they were 0's. First I made the first column nullable. Then I set the data for the column to null. Then I set the column as an index. Then I made it a primary key with auto incrementing turned on. This is where I used another persons answer above:

ALTER TABLE `table_name` CHANGE COLUMN `colum_name` `colum_name` INT(11) NOT NULL AUTO_INCREMENT FIRST;

This Added numbers to all the rows of this table starting at one. If I ran the above code first it wasn't working because all the values were 0's. And making it an index was also required before making it auto incrementing. Next I made the column a primary key.

I would use lambda function on a Series of a DataFrame like this:

f = lambda x: 0 if x>100 else 1
df['my_column'] = df['my_column'].map(f)

I do not assert that this is an efficient way, but it works fine.

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

To complement Alex's response, I would add that starting from Python 2.2.0a2, from __future__ import division is a convenient alternative to using lots of float(…)/…. All divisions perform float divisions, except those with //. This works with all versions from 2.2.0a2 on.

Alternatively one can use the setExtremes method also,

yAxis.setExtremes(0, 100);

Or if only one value is needed to be set, just leave other as null

yAxis.setExtremes(null, 100);

If you don't have avahi installed then it's probably cups.

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

You can test it out here.

Since parents() returns the ancestor elements ordered from the closest to the outer ones, you can chain it into eq():

$('#element').parents().eq(0);  // "Father".
$('#element').parents().eq(2);  // "Great-grandfather".

This is an old thread but for more recent Jenkins versions (in my case Jenkins 2.135) that require a particular java JDK the following should help:

Note: This is for Centos 7 , other distros may have differing directory locations although I believe they are correct for ubuntu also.

Modify /etc/sysconfig/jenkins and set variable JENKINS_JAVA_CMD="/<your desired jvm>/bin/java" (root access require)

Example:

JENKINS_JAVA_CMD="/usr/lib/jvm/java-1.8.0-openjdk/bin/java"

Restart Jenkins (if jenkins is run as a service sudo service jenkins stop then sudo service jenkins start)

The above fixed my Jenkins install not starting after I upgraded to Java 10 and Jenkins to 2.135

java jenkins java-home ubuntu centos

The following query worked for me in Oracle Database 12c Release 12.1.0.1.0

SELECT COUNT(*)
FROM stats
GROUP BY 
extract(MONTH FROM TIMESTAMP),
extract(MONTH FROM TIMESTAMP),
extract(YEAR  FROM TIMESTAMP);

I've use this :

except (socket.timeout, KeyboardInterrupt) as e:
    logging.debug("Exception : {}".format(str(e.__str__).split(" ")[3]))
    break

Let me know if it does not work for you !!

Use PushState and Precomposition

The current (2015) way to do this is using the JavaScript pushState method.

PushState changes the URL in the top browser bar without reloading the page. Say you have a page containing tabs. The tabs hide and show content, and the content is inserted dynamically, either using AJAX or by simply setting display:none and display:block to hide and show the correct tab content.

When the tabs are clicked, use pushState to update the url in the address bar. When the page is rendered, use the value in the address bar to determine which tab to show. Angular routing will do this for you automatically.

Precomposition

There are two ways to hit a PushState Single Page App (SPA)

1. Via PushState, where the user clicks a PushState link and the content is AJAXed in.
2. By hitting the URL directly.

The initial hit on the site will involve hitting the URL directly. Subsequent hits will simply AJAX in content as the PushState updates the URL.

Crawlers harvest links from a page then add them to a queue for later processing. This means that for a crawler, every hit on the server is a direct hit, they don't navigate via Pushstate.

Precomposition bundles the initial payload into the first response from the server, possibly as a JSON object. This allows the Search Engine to render the page without executing the AJAX call.

There is some evidence to suggest that Google might not execute AJAX requests. More on this here:

https://web.archive.org/web/20160318211223/http://www.analog-ni.co/precomposing-a-spa-may-become-the-holy-grail-to-seo

Search Engines can read and execute JavaScript

Google has been able to parse JavaScript for some time now, it's why they originally developed Chrome, to act as a full featured headless browser for the Google spider. If a link has a valid href attribute, the new URL can be indexed. There's nothing more to do.

If clicking a link in addition triggers a pushState call, the site can be navigated by the user via PushState.

Search Engine Support for PushState URLs

PushState is currently supported by Google and Bing.

Google

Here's Matt Cutts responding to Paul Irish's question about PushState for SEO:

http://youtu.be/yiAF9VdvRPw

Here is Google announcing full JavaScript support for the spider:

http://googlewebmastercentral.blogspot.de/2014/05/understanding-web-pages-better.html

The upshot is that Google supports PushState and will index PushState URLs.

See also Google webmaster tools' fetch as Googlebot. You will see your JavaScript (including Angular) is executed.

Bing

Here is Bing's announcement of support for pretty PushState URLs dated March 2013:

http://blogs.bing.com/webmaster/2013/03/21/search-engine-optimization-best-practices-for-ajax-urls/

Don't use HashBangs #!

Hashbang urls were an ugly stopgap requiring the developer to provide a pre-rendered version of the site at a special location. They still work, but you don't need to use them.

Hashbang URLs look like this:

domain.com/#!path/to/resource

This would be paired with a metatag like this:

<meta name="fragment" content="!">

Google will not index them in this form, but will instead pull a static version of the site from the _escaped_fragments_ URL and index that.

Pushstate URLs look like any ordinary URL:

domain.com/path/to/resource

The difference is that Angular handles them for you by intercepting the change to document.location dealing with it in JavaScript.

If you want to use PushState URLs (and you probably do) take out all the old hash style URLs and metatags and simply enable HTML5 mode in your config block.

Testing your site

Google Webmaster tools now contains a tool which will allow you to fetch a URL as google, and render JavaScript as Google renders it.

https://www.google.com/webmasters/tools/googlebot-fetch

Generating PushState URLs in Angular

To generate real URLs in Angular, rather than # prefixed ones, set HTML5 mode on your $locationProvider object.

$locationProvider.html5Mode(true);

Server Side

Since you are using real URLs, you will need to ensure the same template (plus some precomposed content) gets shipped by your server for all valid URLs. How you do this will vary depending on your server architecture.

Sitemap

Your app may use unusual forms of navigation, for example hover or scroll. To ensure Google is able to drive your app, I would probably suggest creating a sitemap, a simple list of all the urls your app responds to. You can place this at the default location (/sitemap or /sitemap.xml), or tell Google about it using webmaster tools.

It's a good idea to have a sitemap anyway.

Browser support

Pushstate works in IE10. In older browsers, Angular will automatically fall back to hash style URLs

A demo page

The following content is rendered using a pushstate URL with precomposition:

http://html5.gingerhost.com/london

As can be verified, at this link, the content is indexed and is appearing in Google.

Serving 404 and 301 Header status codes

Because the search engine will always hit your server for every request, you can serve header status codes from your server and expect Google to see them.

As a one liner:

ImageIO.write(Scalr.resize(ImageIO.read(...), 150));

First of all you can use the short notation @click instead of v-on:click for readability purposes.

Second You can use a click event handler that calls other functions/methods as @Tushar mentioned in his comment above, so you end up with something like this :

<div id="app">
   <div @click="handler('foo','bar')">
       Hi, click me!
   </div>
</div>

<!-- link to vue.js !--> 
<script src="vue.js"></script>

<script>
   (function(){
        var vm = new Vue({
            el:'#app',
            methods:{
                method1:function(arg){
                    console.log('method1: ',arg);
                },
                method2:function(arg){
                    console.log('method2: ',arg);
                },
                handler:function(arg1,arg2){
                    this.method1(arg1);
                    this.method2(arg2);
                }
            }
        })
    }()); 
</script>

You can do that: Postman -> Import -> Link -> {root_url}/v2/api-docs

I think my answer to my own question here is the simplest solution to what you are trying to do:

1. Select the cell where the first line of text from the file should be.

2. Use the Data/Get External Data/From File dialog to select the text file to import.

3. Format the imported text as required.

4. In the Import Data dialog that opens, click on Properties...

5. Uncheck the Prompt for file name on refresh box.

6. Whenever the external file changes, click the Data/Get External Data/Refresh All button.

Note: in your case, you should probably want to skip step #5.

I had this issue too because I was filtering /src/main/resources and forgot I had added a keystore (*.jks) binary to this directory.

Add a "resource" block with exclusions for binary files and your problem may be resolved.

<build>
  <finalName>somename</finalName>
  <testResources>
    <testResource>
      <directory>src/test/resources</directory>
      <filtering>false</filtering>
    </testResource>
  </testResources>
  <resources>
    <resource>
      <directory>src/main/resources</directory>
      <filtering>true</filtering>
      <excludes>
        <exclude>*.jks</exclude>
        <exclude>*.png</exclude>
      </excludes>        
    </resource>
  </resources>
...

I am using JUnit 4, and what worked for me is changing the IntelliJ settings for 'Gradle -> Run Tests Using' from 'Gradle (default)' to 'IntelliJ IDEA'.

You need the static version of the library to link it.

A shared library is actually an executable in a special format with entry points specified (and some sticky addressing issues included). It does not have all the information needed to link statically.

You can't statically link a shared library (or dynamically link a static one).

The flag -static will force the linker to use static libraries (.a) instead of shared (.so) ones. But static libraries aren't always installed by default, so you may have to install the static library yourself.

Another possible approach is to use statifier or Ermine. Both tools take as input a dynamically linked executable and as output create a self-contained executable with all shared libraries embedded.

This is use mostly for assigning variable, and it uses binomial conditioning eg.

var time = Date().getHours(); // or something

var clockTime = time > 12 ? 'PM' : 'AM' ;

There is no ElseIf, for the sake of development don't use chaining, you can use switch which is much faster if you have multiple conditioning in .js
