In PCRE and similar variants, you can actually create a regex that matches any line not containing a value:

^(?:(?!Andrea).)*$

This is called a tempered greedy token. The downside is that it doesn't perform well.

Just in case, you might have had unbalanced brackets, you can likely design some expression with recursion similar to,

\[(([^\]\[]+)|(?R))*+\]

which of course, it would relate to the language or RegEx engine that you might be using.

RegEx Demo 1

Other than that,

\[([^\]\[\r\n]*)\]

RegEx Demo 2

or,

(?<=\[)[^\]\[\r\n]*(?=\])

RegEx Demo 3

are good options to explore.

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

Regular expression to match balanced parentheses

I ended up using the bootstrap 3 dropdown button, I'm posting my solution here in case it helps someone in future. Adding the bootstrap 3 list-inline to the class for the ul causes it to display in a nicely compact format as well.

<div class="btn-group">
    <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
        Select icon <span class="caret"></span>
    </button>
    <ul class="dropdown-menu list-inline" role="menu">
        <li><span class="glyphicon glyphicon-cutlery"></span></li>
        <li><span class="glyphicon glyphicon-fire"></span></li>
        <li><span class="glyphicon glyphicon-glass"></span></li>
        <li><span class="glyphicon glyphicon-heart"></span></li>          
    </ul>
</div>

I'm using Angular.js so this is the actual code I used:

<div class="btn-group">
            <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
                Avatar <span class="caret"></span>
            </button>
            <ul class="dropdown-menu list-inline" role="menu">
                <li ng-repeat="avatar in avatars" ng-click="avatarSelected(avatar)">
                    <span ng-class="getAvatar(avatar)"></span>
                </li>
            </ul>
        </div>

And in my controller:

$scope.avatars=['cutlery','eye-open','flag','flash','glass','fire','hand-right','heart','heart-empty','leaf','music','send','star','star-empty','tint','tower','tree-conifer','tree-deciduous','usd','user','wrench','time','road','cloud'];

$scope.getAvatar=function(avatar){
     return 'glyphicon glyphicon-'+avatar;
};

if you want to pass POST variables, you have to use a HTML Form:

<form action="http://localhost:8080/login" method="POST" target="_blank">
    <input type="text" name="cid" />
    <input type="password" name="pwd" />
    <input type="submit" value="open" />
</form>

or:

if you want to pass GET variables in an URL, write them without single-quotes:

http://yourdomain.com/login?cid=username&pwd=password

here's how to create the string above with javascrpt variables:

myu = document.getElementById('cid').value;
myp = document.getElementById('pwd').value;
window.open("http://localhost:8080/login?cid="+ myu +"&pwd="+ myp ,"MyTargetWindowName");

in the document with that url, you have to read the GET parameters. if it's in php, use:

$_GET['username']

be aware: to transmit passwords that way is a big security leak!

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

Typescript

public blobToFile = (theBlob: Blob, fileName:string): File => {       
    return new File([theBlob], fileName, { lastModified: new Date().getTime(), type: theBlob.type })
}

Javascript

function blobToFile(theBlob, fileName){       
    return new File([theBlob], fileName, { lastModified: new Date().getTime(), type: theBlob.type })
}

Output

I'm running Chrome version 60 and none of the previous CSS answers worked.

I found that Chrome was adding the blue highlight via the outline style. Adding the following CSS fixed it for me:

:focus {
    outline: none !important;
}

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

Does it matter which I use?

Yes! The second is vastly more readable. You are trading one line which concisely expresses what you want against nine lines of effectively clutter.

Which is faster?

Neither.

Is it a better practice to use the shortest code whenever possible?

Not “whenever possible” but certainly whenever possible without detriment effects. Shorter code is at least potentially more readable since it focuses on the relevant part rather than on incidental effects (“boilerplate code”).

In Excel 2007, unlock the cells that you want enter your data into. Go to Review

 > Select Locked Cells (already selected)
 > Select unlocked Cells (already selected)

One special case: a cookie has no path.

In this case set path as cookie.setPath(request.getRequestURI())

The javascript sets cookie without path so the browser shows it as cookie for the current page only. If I try to send the expired cookie with path == / the browser shows two cookies: one expired with path == / and another one with path == current page.

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

As @CubanX suggested, I've split this answer from my original:

Here is a method which is several times faster than xargs and may scale much more with tweaking. It uses the Github API, a personal access token, and leverages the utility parallel.

git tag | sorting_processing_etc | parallel --jobs 2 curl -i -X DELETE \ 
https://api.github.com/repos/My_Account/my_repo/git/refs/tags/{} -H 
\"authorization: token GIT_OAUTH_OR_PERSONAL_KEY_HERE\"  \
-H \"cache-control: no-cache\"`

parallel has many operating modes, but generally parallelizes any command you give it while allowing you to set limits on the number of processes. You can alter the --jobs 2 parameter to allow faster operation, but I had problems with Github's rate limits, which are currently 5000/hr, but also seems to have an undocumented short-term limit as well.

After this, you'll probably want to delete your local tags too. This is much faster so we can go back to using xargs and git tag -d, which is sufficient.

git tag | sorting_processing_etc | xargs -L 1 git tag -d

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

There is no concept of folders or directories in S3. You can create file names like "abc/xys/uvw/123.jpg", which many S3 access tools like S3Fox show like a directory structure, but it's actually just a single file in a bucket.

Can I put my method readConfig() into constructor?

Invoking a not overridable method in a constructor is an acceptable approach.
While if the method is only used by the constructor you may wonder if extracting it into a method (even private) is really required.

If you choose to extract some logic done by the constructor into a method, as for any method you have to choose a access modifier that fits to the method requirement but in this specific case it matters further as protecting the method against the overriding of the method has to be done at risk of making the super class constructor inconsistent.

So it should be private if it is used only by the constructor(s) (and instance methods) of the class.
Otherwise it should be both package-private and final if the method is reused inside the package or in the subclasses.

which would give me benefit of one time calling or is there another mechanism to do that ?

You don't have any benefit or drawback to use this way.
I don't encourage to perform much logic in constructors but in some cases it may make sense to init multiple things in a constructor.
For example the copy constructor may perform a lot of things.
Multiple JDK classes illustrate that.
Take for example the HashMap copy constructor that constructs a new HashMap with the same mappings as the specified Map parameter :

public HashMap(Map<? extends K, ? extends V> m) {
    this.loadFactor = DEFAULT_LOAD_FACTOR;
    putMapEntries(m, false);
}

final void putMapEntries(Map<? extends K, ? extends V> m, boolean evict) {
    int s = m.size();
    if (s > 0) {
        if (table == null) { // pre-size
            float ft = ((float)s / loadFactor) + 1.0F;
            int t = ((ft < (float)MAXIMUM_CAPACITY) ?
                     (int)ft : MAXIMUM_CAPACITY);
            if (t > threshold)
                threshold = tableSizeFor(t);
        }
        else if (s > threshold)
            resize();
        for (Map.Entry<? extends K, ? extends V> e : m.entrySet()) {
            K key = e.getKey();
            V value = e.getValue();
            putVal(hash(key), key, value, false, evict);
        }
    }
}

Extracting the logic of the map populating in putMapEntries() is a good thing because it allows :

• reusing the method in other contexts. For example clone() and putAll() use it too
• (minor but interesting) giving a meaningful name that conveys the performed logic

this is the solution to close menu when click on anchor then apply this line in list item

     data-target="#sidenav-collapse-main" data-toggle="collapse"

the real example that work for me is below

      <li class="nav-item" data-target="#sidenav-collapse-main" data- 
      toggle="collapse" >
      <a class="nav-link" routerLinkActive="active" routerLink="/admin/users">
        <i class="ni ni-single-02  text-orange"></i> Users
      </a>
      </li>

if (isset($_POST['submit'])) {

for($i = 0; $i<= 3; $i++){

    if(isset($_POST['books'][$i]))

        $book .= ' '.$_POST['books'][$i];
}

Look at https://expressjs.com/en/resources/middleware/cors.html You have to use cors.

Install:

$ npm install cors

const cors = require('cors');
app.use(cors());

You have to put this code in your node server.

I tried the answers here in a giant for...if loop, but didn't get any joy - so I did it like this, maybe messy but did the job:

 # EXP_LIST2 is iterated    
 # imagine a for loop
     EXP_LIST="List item"    
     EXP_LIST2="$EXP_LIST2 \n $EXP_LIST"
 done 
 echo -e $EXP_LIST2

although that added a space to the list, which is fine - I wanted it indented a bit. Also presume the "\n" could be printed in the original $EP_LIST.

If your path to view is true first try to config:cache and route:cache if nothing changed check your resource path permission are true.

example: your can do it in ubuntu with :

sudo chgrp -R www-data resources/views
sudo usermod -a -G www-data $USER

I found this way to expand a DNS RR hostname that expands into a list of IPs, into the list of member hostnames:

#!/usr/bin/python

def expand_dnsname(dnsname):
    from socket import getaddrinfo
    from dns import reversename, resolver
    namelist = [ ]
    # expand hostname into dict of ip addresses
    iplist = dict()
    for answer in getaddrinfo(dnsname, 80):
        ipa = str(answer[4][0])
        iplist[ipa] = 0
    # run through the list of IP addresses to get hostnames
    for ipaddr in sorted(iplist):
        rev_name = reversename.from_address(ipaddr)
        # run through all the hostnames returned, ignoring the dnsname
        for answer in resolver.query(rev_name, "PTR"):
            name = str(answer)
            if name != dnsname:
                # add it to the list of answers
                namelist.append(name)
                break
    # if no other choice, return the dnsname
    if len(namelist) == 0:
        namelist.append(dnsname)
    # return the sorted namelist
    namelist = sorted(namelist)
    return namelist

namelist = expand_dnsname('google.com.')
for name in namelist:
    print name

Which, when I run it, lists a few 1e100.net hostnames:

This works for me every time:

navigator.geolocation.getCurrentPosition(getCoor, errorCoor, {maximumAge:60000, timeout:5000, enableHighAccuracy:true});

Though it isn't very accurate. The funny thing is that on the same device if I run this it puts me off about 100 meters (every time), but if I go to google's maps it finds my location exactly. So although I think the enableHighAccuracy: true helps it to work consistently, it doesn't seem to make it any more accurate...

I solved the problem by using the Rnd() function:

Function RollD6() As UInteger
        RollD6 = (Math.Floor(6 * Rnd())) + 1
        Return RollD6
End Function

When the form loads, I use the Randomize() method to make sure I don't always get the same sequence of random numbers from run to run.

When I need to do this, I make the other values data-values and then use js to assign them to a hidden input

<select id=select>
<option value=1 data-othervalue=2 data-someothervalue=3>
//...
</select>

<input type=hidden name=otherValue id=otherValue />
<input type=hidden name=someOtherValue id=someOtherValue />

<script>
$('#select').change(function () {
var otherValue=$(this).find('option:selected').attr('data-othervalue');
var someOtherValue=$(this).find('option:selected').attr('data-someothervalue');
$('#otherValue').val(otherValue);
$('#someOtherValue').val(someOtherValue);
});
</script>

Despite not fully answering the original question, this is probably what most people googling this wanted to see.

For GCC:

Simplest Way with Jquery -

var finalObj = $.extend(obj1, obj2);

Without Jquery -

var finalobj={};
for(var _obj in obj1) finalobj[_obj ]=obj1[_obj];
for(var _obj in obj2) finalobj[_obj ]=obj2[_obj];

First you create a MySQL table to store images, like for example:

create table testblob (
    image_id        tinyint(3)  not null default '0',
    image_type      varchar(25) not null default '',
    image           blob        not null,
    image_size      varchar(25) not null default '',
    image_ctgy      varchar(25) not null default '',
    image_name      varchar(50) not null default ''
);

Then you can write an image to the database like:

/***
 * All of the below MySQL_ commands can be easily
 * translated to MySQLi_ with the additions as commented
 ***/ 
$imgData = file_get_contents($filename);
$size = getimagesize($filename);
mysql_connect("localhost", "$username", "$password");
mysql_select_db ("$dbname");
// mysqli 
// $link = mysqli_connect("localhost", $username, $password,$dbname); 
$sql = sprintf("INSERT INTO testblob
    (image_type, image, image_size, image_name)
    VALUES
    ('%s', '%s', '%d', '%s')",
    /***
     * For all mysqli_ functions below, the syntax is:
     * mysqli_whartever($link, $functionContents); 
     ***/
    mysql_real_escape_string($size['mime']),
    mysql_real_escape_string($imgData),
    $size[3],
    mysql_real_escape_string($_FILES['userfile']['name'])
    );
mysql_query($sql);

You can display an image from the database in a web page with:

$link = mysql_connect("localhost", "username", "password");
mysql_select_db("testblob");
$sql = "SELECT image FROM testblob WHERE image_id=0";
$result = mysql_query("$sql");
header("Content-type: image/jpeg");
echo mysql_result($result, 0);
mysql_close($link);

Though it's too late, but if someone face the same thing that i went through.. For me, the problem occurred due to my Emulator. My emulator was running in SafeMood. When i tried most of the solutions above, and these solutions didn’t worked for me. The thing that worked for me was restarting my Emulator without SafeMood. First it was started in SafeMood automatically and problem occurred. Then when i disable SafeMood and restart my Emulator it did the trick!

I think the best way is to put your includes in your PHP include path. There are various ways to do this depending on your setup.

Then you can simply refer to

require_once 'inc1.php';

from inside any file regardless of where it is whether in your includes or in your web accessible files, or any level of nested subdirectories.

This allows you to have your include files outside the web server root, which is a best practice.

e.g.

site directory
    html (web root)
        your web-accessible files
    includes
        your include files

Also, check out __autoload for lazy loading of class files

http://www.google.com/search?q=setting+php+include+path

http://www.google.com/search?q=__autoload

An include is just like a code insertion. You get in your included code the exact same variables you have in your base code. So you can do this in your main file :

<?
    if ($condition == true)
    {
        $id = 12345;
        include 'myFile.php';
    }
?>

And in "myFile.php" :

<?
    echo 'My id is : ' . $id . '!';
?>

This will output :

My id is 12345 !

It really depends on the IE versions ... I found this excellent resource that is up to date from IE6-10:

CSS hack for Internet Explorer 6

It is called the Star HTML Hack and looks as follows:

• html .color {color: #F00;} This hack uses fully valid CSS.

CSS hack for Internet Explorer 7

It is called the Star Plus Hack.

*:first-child+html .color {color: #F00;} Or a shorter version:

*+html .color {color: #F00;} Like the star HTML hack, this uses valid CSS.

CSS hack for Internet Explorer 8

@media \0screen { .color {color: #F00;} } This hacks does not use valid CSS.

CSS hack for Internet Explorer 9

:root .color {color: #F00\9;} This hacks also does not use valid CSS.

Added 2013.02.04: Unfortunately IE10 understands this hack.

CSS hack for Internet Explorer 10

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) { .color {color: #F00;} } This hacks also does not use valid CSS.

Add cellpadding and cellspacing to solve it. Edit: Also removed double pixel border.

<style>
td
{border-left:1px solid black;
border-top:1px solid black;}
table
{border-right:1px solid black;
border-bottom:1px solid black;}
</style>
<html>
    <body>
        <table cellpadding="0" cellspacing="0">

                <td width="65" >
                    Foo2

                <td>
                    Bar3
                </td>
            </tr>
            <tr >
                <td>
                    Bar1

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

$("ul[data-group='Companies'] li[data-company='Microsoft']") //Get all elements with data-company="Microsoft" below "Companies"

$("ul[data-group='Companies'] li:not([data-company='Microsoft'])") //get all elements with data-company!="Microsoft" below "Companies"

Look in to jQuery Selectors :contains is a selector

here is info on the :contains selector

LINQ is very effective and easy to use on Lists rather than DataTable. I can see the above answers have a loop(for, foreach), which I will not prefer.

So the best thing to select a perticular column from a DataTable is just use a DataView to filter the column and use it as you want.

Find it here how to do this.

DataView dtView = new DataView(dtYourDataTable);
DataTable dtTableWithOneColumn= dtView .ToTable(true, "ColumnA");

Now the DataTable dtTableWithOneColumn contains only one column(ColumnA).

1. Create the ArrayList like ArrayList action.

   In JDK 1.5 or higher use ArrayList <string[]> reference name.

   In JDK 1.4 or lower use ArrayList reference name.

2. Specify the access specifiers:

   • public, can be accessed anywhere
   • private, accessed within the class
   • protected, accessed within the class and different package subclasses

3. Then specify the reference it will be assigned in

   action = new ArrayList<String[]>();
   

4. In JVM new keyword will allocate memory in runtime for the object.

   You should not assigned the value where declared, because you are asking without fixed size.

5. Finally you can be use the add() method in ArrayList. Use like

   action.add(new string[how much you need])
   

   It will allocate the specific memory area in heap.

run cmd.exe and do the following:

> cd "long path name"
> command

Then command.com will come up and display only short paths.

I had the similar issue using Flurl.Http:

Flurl.Http.FlurlHttpException: Call failed. Cannot send a content-body with this verb-type. GET http://******:8301/api/v1/agents/**** ---> System.Net.ProtocolViolationException: Cannot send a content-body with this verb-type.

The problem was I used .WithHeader("Content-Type", "application/json") when creating IFlurlRequest.

change the MaxClients directive. it is now on 256.

I wrote this for strings AND functionality (I know it's not the question but I searched for it and got here), maybe it can be expanded.

String.prototype.contains = function(str) {
  return this.indexOf(str) != -1;
};

String.prototype.containsAll = function(strArray) {
  for (var i = 0; i < strArray.length; i++) {
    if (!this.contains(strArray[i])) {
      return false;
    }
  }
  return true;
}

app.filter('filterMultiple', function() {
  return function(items, filterDict) {
    return items.filter(function(item) {
      for (filterKey in filterDict) {
        if (filterDict[filterKey] instanceof Array) {
          if (!item[filterKey].containsAll(filterDict[filterKey])) {
            return false;
          }
        } else {
          if (!item[filterKey].contains(filterDict[filterKey])) {
            return false;
          }
        }
      }
      return true;
    });  
  };
});

Usage:

<li ng-repeat="x in array | filterMultiple:{key1: value1, key2:[value21, value22]}">{{x.name}}</li>

I think what you are looking for is the 'not' operator?

Reference page: http://www.tutorialspoint.com/python/logical_operators_example.htm

So after struggling with this issue for quite some time, this is what could help you:

from PIL import Image

instead of

import Image

Also, if your Image file is not loading and you're getting an error "No file or directory" then you should do this:

path=r'C:\ABC\Users\Pictures\image.jpg'

and then open the file

image=Image.open(path)

INSERT INTO preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,
uploader_id,is_deleted,last_updated) 

SELECT '4827499',pre_image_status,file_extension,reviewer_id,
uploader_id,'0',last_updated FROM preliminary_image WHERE style_id=4827488

Analysis

We can use above query if we want to copy data from one table to another table in mysql

1. Here source and destination table are same, we can use different tables also.
2. Few columns we are not copying like style_id and is_deleted so we selected them hard coded from another table
3. Table we used in source also contains auto increment field so we left that column and it get inserted automatically with execution of query.

Execution results

1 queries executed, 1 success, 0 errors, 0 warnings

Query: insert into preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,uploader_id,is_deleted,last_updated) select ...

5 row(s) affected

Execution Time : 0.385 sec Transfer Time : 0 sec Total Time : 0.386 sec

Try this:

grep "string to search for" FileNameToSearch | cut -d ":" -f 4 | sort -n | uniq -c

Sample:

grep "SMTP connect from unknown" maillog | cut -d ":" -f 4 | sort -n | uniq -c
  6  SMTP connect from unknown [188.190.118.90]
 54  SMTP connect from unknown [62.193.131.114]
  3  SMTP connect from unknown [91.222.51.253]

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

Make the outer loop a while loop, and "Exit While" in the if statement.

Experienced this when I downloaded a page for offline view.

I just had to remove the integrity="*****" and crossorigin="anonymous" attributes from all <link> and <script> tags

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
int res = 0;
if (bytes == null)
    return res;


for (int i=0;i<bytes.length;i++){
    res = res | ((bytes[i] & 0xff) << i*8);
}
return res;
}

You need to add JQuery js before adding bootstrap js file, because BootStrap use jqueries function. So make sure to load first jquery js and then bootstap js file.

<!-- JQuery Core JavaScript -->
<script src="app/js/jquery.min.js"></script>

<!-- Bootstrap Core JavaScript -->
<script src="app/js/bootstrap.min.js"></script>

Install Fake Sendmail (download sendmail.zip). Then configure C:\wamp\sendmail\sendmail.ini:

smtp_server=smtp.gmail.com
smtp_port=465
[email protected]
auth_password=your_password

The above will work against a Gmail account. And then configure php.ini:

sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

Now, restart Apache, and that is basically all you need to do.

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");

To be more precise about Mac OS X (now called MacOS) / in the Finder is interpreted to : in the Unix file system.

This was done for backward compatibility when Apple moved from Classic Mac OS.

It is legitimate to use a / in a file name in the Finder, looking at the same file in the terminal it will show up with a :.

And it works the other way around too: you can't use a / in a file name with the terminal, but a : is OK and will show up as a / in the Finder.

Some applications may be more restrictive and prohibit both characters to avoid confusion or because they kept logic from previous Classic Mac OS or for name compatibility between platforms.

How to remove Node.js from Windows:

1. Take a deep breath.

2. Run npm cache clean --force

3. Uninstall from Programs & Features with the uninstaller.

4. Reboot (or you probably can get away with killing all node-related processes from Task Manager).

5. Look for these folders and remove them (and their contents) if any still exist. Depending on the version you installed, UAC settings, and CPU architecture, these may or may not exist:

   • C:\Program Files (x86)\Nodejs
   • C:\Program Files\Nodejs
   • C:\Users\{User}\AppData\Roaming\npm (or %appdata%\npm)
   • C:\Users\{User}\AppData\Roaming\npm-cache (or %appdata%\npm-cache)
   • C:\Users\{User}\.npmrc (and possibly check for that without the . prefix too)
   • C:\Users\{User}\AppData\Local\Temp\npm-*

6. Check your %PATH% environment variable to ensure no references to Nodejs or npm exist.

7. If it's still not uninstalled, type where node at the command prompt and you'll see where it resides -- delete that (and probably the parent directory) too.

8. Reboot, for good measure.

Weight sum works exactly as you want (like other answers you don't have to sum all the weights on parent layout). On child view specify the weight you want it to take. Don't forget to specify

android:layout_width="0dp" 

Following is an example

    <LinearLayout
                android:layout_width="500dp"
                android:layout_height="20dp" >

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="3"
                    android:background="@android:color/holo_green_light"
                    android:gravity="center"
                    android:text="30%"
                    android:textColor="@android:color/white" >
                </TextView>

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="2"
                    android:background="@android:color/holo_blue_bright"
                    android:gravity="center"
                    android:text="20%"
                    android:textColor="@android:color/white" >
                </TextView>

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="5"
                    android:background="@android:color/holo_orange_dark"
                    android:gravity="center"
                    android:text="50%"
                    android:textColor="@android:color/white" >
                </TextView>
 </LinearLayout>

This will look like

If all your divs start with editDialog as you stated, then you can use the following selector:

$("div[id^='editDialog']")

Or you could use a class selector instead if it's easier for you

<div id="editDialog-0" class="editDialog">...</div>

$(".editDialog")

Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:

% python3 -c "import sys;print(sys.path)"
['', 
'/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

where the first path '' denotes the current dir., the 2nd path is via

%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite 

which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.

As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:

% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f18a44ff740 (most recent call first):
Aborted (core dumped)

Note that if you start a Python script, the CWD will be the script's directory. For example:

username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:

username@bud:~/Documents/DjangoTutorial% python3 
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', 
'/home/username/Documents']
>>> from Python import Fibonacci as fibo

or via

% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['', 
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo

A modification of the code by @CarloCannas:

public static void sudo(String...strings) {
    try{
        Process su = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

(You are welcome to find a better place for outputStream.close())

Usage example:

private static void suMkdirs(String path) {
    if (!new File(path).isDirectory()) {
        sudo("mkdir -p "+path);
    }
}

Update: To get the result (the output to stdout), use:

public static String sudoForResult(String...strings) {
    String res = "";
    DataOutputStream outputStream = null;
    InputStream response = null;
    try{
        Process su = Runtime.getRuntime().exec("su");
        outputStream = new DataOutputStream(su.getOutputStream());
        response = su.getInputStream();

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        res = readFully(response);
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        Closer.closeSilently(outputStream, response);
    }
    return res;
}
public static String readFully(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = is.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString("UTF-8");
}

The utility to silently close a number of Closeables (So?ket may be no Closeable) is:

public class Closer {
// closeAll()
public static void closeSilently(Object... xs) {
    // Note: on Android API levels prior to 19 Socket does not implement Closeable
    for (Object x : xs) {
        if (x != null) {
            try {
                Log.d("closing: "+x);
                if (x instanceof Closeable) {
                    ((Closeable)x).close();
                } else if (x instanceof Socket) {
                    ((Socket)x).close();
                } else if (x instanceof DatagramSocket) {
                    ((DatagramSocket)x).close();
                } else {
                    Log.d("cannot close: "+x);
                    throw new RuntimeException("cannot close "+x);
                }
            } catch (Throwable e) {
                Log.x(e);
            }
        }
    }
}
}

Any decent text editor has a search&replace facility that supports regular expressions.

If however, you have reason to reinvent the wheel in Java, you can do:

Path path = Paths.get("test.txt");
Charset charset = StandardCharsets.UTF_8;

String content = new String(Files.readAllBytes(path), charset);
content = content.replaceAll("foo", "bar");
Files.write(path, content.getBytes(charset));

This only works for Java 7 or newer. If you are stuck on an older Java, you can do:

String content = IOUtils.toString(new FileInputStream(myfile), myencoding);
content = content.replaceAll(myPattern, myReplacement);
IOUtils.write(content, new FileOutputStream(myfile), myencoding);

In this case, you'll need to add error handling and close the streams after you are done with them.

IOUtils is documented at http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/IOUtils.html

now in Kotlin you can run threads this way:

class SimpleRunnable: Runnable {
    public override fun run() {
        println("${Thread.currentThread()} has run.")
    }
}
fun main(args: Array<String>) {
    val thread = SimpleThread()
    thread.start() // Will output: Thread[Thread-0,5,main] has run.
    val runnable = SimpleRunnable()
    val thread1 = Thread(runnable)
    thread1.start() // Will output: Thread[Thread-1,5,main] has run
}

If you are looking at a Table, a Pivot Table, or something with conditional formatting, you can try:

ActiveCell.DisplayFormat.Interior.Color

This also seems to work just fine on regular cells.

Personally, I prefer to use empty collections instead of null and have the algorithms work in a way that for the algorithm it does not matter if the collection is empty or not.

You might take a look at JavaScience's source for OpenSSLKey

There's code in there that does exactly what you want to do.

In fact, they have a lot of crypto source code available here.

Source code snippet:

//------- Parses binary ans.1 RSA private key; returns RSACryptoServiceProvider  ---
public static RSACryptoServiceProvider DecodeRSAPrivateKey(byte[] privkey)
{
        byte[] MODULUS, E, D, P, Q, DP, DQ, IQ ;

        // ---------  Set up stream to decode the asn.1 encoded RSA private key  ------
        MemoryStream  mem = new MemoryStream(privkey) ;
        BinaryReader binr = new BinaryReader(mem) ;    //wrap Memory Stream with BinaryReader for easy reading
        byte bt = 0;
        ushort twobytes = 0;
        int elems = 0;
        try {
                twobytes = binr.ReadUInt16();
                if (twobytes == 0x8130) //data read as little endian order (actual data order for Sequence is 30 81)
                        binr.ReadByte();        //advance 1 byte
                else if (twobytes == 0x8230)
                        binr.ReadInt16();       //advance 2 bytes
                else
                        return null;

                twobytes = binr.ReadUInt16();
                if (twobytes != 0x0102) //version number
                        return null;
                bt = binr.ReadByte();
                if (bt !=0x00)
                        return null;


                //------  all private key components are Integer sequences ----
                elems = GetIntegerSize(binr);
                MODULUS = binr.ReadBytes(elems);

                elems = GetIntegerSize(binr);
                E = binr.ReadBytes(elems) ;

                elems = GetIntegerSize(binr);
                D = binr.ReadBytes(elems) ;

                elems = GetIntegerSize(binr);
                P = binr.ReadBytes(elems) ;

                elems = GetIntegerSize(binr);
                Q = binr.ReadBytes(elems) ;

                elems = GetIntegerSize(binr);
                DP = binr.ReadBytes(elems) ;

                elems = GetIntegerSize(binr);

                elems = GetIntegerSize(binr);
                IQ = binr.ReadBytes(elems) ;

                Console.WriteLine("showing components ..");
                if (verbose) {
                        showBytes("\nModulus", MODULUS) ;
                        showBytes("\nExponent", E);

                        showBytes("\nP", P);
                        showBytes("\nQ", Q);
                        showBytes("\nDP", DP);
                        showBytes("\nDQ", DQ);
                        showBytes("\nIQ", IQ);
                }

try

$("#mylist").children().length

I tried several of the options here. For all that I tried, the spacing was uneven, or was even but when I shrank the window width enough for the subviews to stack, there was no space between stacked views.

Here is what worked for me.

.col-sm-12 { 
  margin-bottom: 2em;
}

<div class="container">
    <div class="row">
        <div class="col-sm-6">
            <div class="col-sm-12">

            </div>
        </div>
        <div class="col-sm-6">
            <div class="col-sm-12">

            </div>
        </div>
    </div>
</div>

Wrap your all statements in !IsPostBack condition on page load.

protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      // all statements
   }
}

This will fix your issue.

The most important thing is, the action created must return partial view, see below.

public ActionResult _YourPartialViewSection()
{
    return PartialView();
}

This one works for me. The --no-color part is, or can be, important if you want a plain string back.

git branch --no-color | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'

there is a simple procedure to do it go to controlpanel->system and security ->system->advanced system settings->advanced->environment variables then add new path enter this in your variable path and values

cursor.copy_from is the fastest solution I've found for bulk inserts by far. Here's a gist I made containing a class named IteratorFile which allows an iterator yielding strings to be read like a file. We can convert each input record to a string using a generator expression. So the solution would be

args = [(1,2), (3,4), (5,6)]
f = IteratorFile(("{}\t{}".format(x[0], x[1]) for x in args))
cursor.copy_from(f, 'table_name', columns=('a', 'b'))

For this trivial size of args it won't make much of a speed difference, but I see big speedups when dealing with thousands+ of rows. It will also be more memory efficient than building a giant query string. An iterator would only ever hold one input record in memory at a time, where at some point you'll run out of memory in your Python process or in Postgres by building the query string.

1) Why does the x-axis (frequency) end at 500? How do I know that there aren't more frequencies or are they just ignored?

It ends at 500Hz because that is the Nyquist frequency of the signal when sampled at 1000Hz. Look at this line in the Mathworks example:

f = Fs/2*linspace(0,1,NFFT/2+1);

The frequency axis of the second plot goes from 0 to Fs/2, or half the sampling frequency. The Nyquist frequency is always half the sampling frequency, because above that, aliasing occurs:

The signal would "fold" back on itself, and appear to be some frequency at or below 500Hz.

2) How do I know the frequencies are between 0 and 500? Shouldn't the FFT tell me, in which limits the frequencies are?

Due to "folding" described above (the Nyquist frequency is also commonly known as the "folding frequency"), it is physically impossible for frequencies above 500Hz to appear in the FFT; higher frequencies will "fold" back and appear as lower frequencies.

Does the FFT only return the amplitude value without the frequency?

Yes, the MATLAB FFT function only returns one vector of amplitudes. However, they map to the frequency points you pass to it.

Let me know what needs clarification so I can help you further.

I agree that Google's Gson is clear and easy to use. But you should create a result class for getting an instance from JSON string. If you can't clarify the result class, use json-simple:

// import static org.hamcrest.CoreMatchers.is;
// import static org.junit.Assert.assertThat;
// import org.json.simple.JSONObject;
// import org.json.simple.JSONValue;
// import org.junit.Test;

@Test
public void json2Object() {
    // given
    String jsonString = "{\"name\" : \"John\",\"age\" : \"20\","
            + "\"address\" : \"some address\","
            + "\"someobject\" : {\"field\" : \"value\"}}";

    // when
    JSONObject object = (JSONObject) JSONValue.parse(jsonString);

    // then
    @SuppressWarnings("unchecked")
    Set<String> keySet = object.keySet();
    for (String key : keySet) {
        Object value = object.get(key);
        System.out.printf("%s=%s (%s)\n", key, value, value.getClass()
                .getSimpleName());
    }

    assertThat(object.get("age").toString(), is("20"));
}

Pros and cons of Gson and json-simple is pretty much like pros and cons of user-defined Java Object and Map. The object you define is clear for all fields (name and type), but less flexible than Map.

I think you are looking for below method:

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID));
    friends.ForEachAsync(a=>a.msgSentBy='1234');
    await db.SaveChangesAsync();
}

This should be the efficient way of handling this.

Now it's 2017, The latest version of XStream requires a converter to make it works as your expected.

A converter supports nested map:

public class MapEntryConverter implements Converter {

    @Override
    public void marshal(Object value, HierarchicalStreamWriter writer, MarshallingContext marshallingContext) {
        AbstractMap map = (AbstractMap) value;
        for (Object obj : map.entrySet()) {
            Map.Entry entry = (Map.Entry) obj;
            writer.startNode(entry.getKey().toString());
            Object val = entry.getValue();
            if (val instanceof Map) {
                marshal(val, writer, marshallingContext);
            } else if (null != val) {
                writer.setValue(val.toString());
            }
            writer.endNode();
        }
    }

    @Override
    public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext unmarshallingContext) {
        Map<String, Object> map = new HashMap<>();

        while(reader.hasMoreChildren()) {
            reader.moveDown();

            String key = reader.getNodeName(); // nodeName aka element's name
            String value = reader.getValue().replaceAll("\\n|\\t", "");
            if (StringUtils.isBlank(value)) {
                map.put(key, unmarshal(reader, unmarshallingContext));
            } else {
                map.put(key, value);
            }

            reader.moveUp();
        }

        return map;
    }

    @Override
    public boolean canConvert(Class clazz) {
        return AbstractMap.class.isAssignableFrom(clazz);
    }
} 

Maybe you've got an object having a method 'constructor' and try to invoke that one.

You may use pip for that without using the network. See in the docs (search for "Install a particular source archive file"). Any of those should work:

pip install relative_path_to_seaborn.tar.gz    
pip install absolute_path_to_seaborn.tar.gz    
pip install file:///absolute_path_to_seaborn.tar.gz    

Or you may uncompress the archive and use setup.py directly with either pip or python:

cd directory_containing_tar.gz
tar -xvzf seaborn-0.10.1.tar.gz
pip install seaborn-0.10.1
python setup.py install

Of course, you should also download required packages and install them the same way before you proceed.

You should have this at the bottom of the index.ios.js file AppRegistry.registerComponent('Point', () => Point); and also import AppRegistry from react-native

This worked for me:

curl -v --cookie "USER_TOKEN=Yes" http://127.0.0.1:5000/

I could see the value in backend using

print request.cookies

 $.ajax({     
     type: "POST",
     url: '/admin/systemgoalssystemgoalupdate?format=html',
     data: formdata,
     success: function (data) {
         console.log(data);
     },
     dataType: "json"
 });

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

import boto3

s3 = boto3.resource('s3')
BUCKET = "test"

s3.Bucket(BUCKET).upload_file("your/local/file", "dump/file")

Open your activity_main.xml . Switch to Design view if you are in text view. Look for the android version,with the android robo icon. Change the android version. Problem solved.

Yup, as everyone's saying, line-height is the thing. Any font you are using, a mid-height character (such as a or ¦, not going through the upper or lower) should go with the same height-length at line-height: 0.6 to 0.65.

You can also set figure size by passing dictionary to rc parameter with key 'figure.figsize' in seaborn set method:

import seaborn as sns

sns.set(rc={'figure.figsize':(11.7,8.27)})

Other alternative may be to use figure.figsize of rcParams to set figure size as below:

from matplotlib import rcParams

# figure size in inches
rcParams['figure.figsize'] = 11.7,8.27

More details can be found in matplotlib documentation

I started this gist a year ago: https://gist.github.com/PascalPrecht/5411171

Brian Ford (member of the core team) has written this blog post about it: http://briantford.com/blog/angular-bower

And then we started with this component spec (which is not quite complete): https://github.com/angular/angular-component-spec

Since the last ng-conf there's this document for best practices by the core team: https://docs.google.com/document/d/1XXMvReO8-Awi1EZXAXS4PzDzdNvV6pGcuaF4Q9821Es/pub

My solution with Angular 4.0.1: Just showing the UI for required CVC input - where the CVC must be exactly 3 digits:

    <form #paymentCardForm="ngForm">         
...
        <md-input-container align="start">
            <input #cvc2="ngModel" mdInput type="text" id="cvc2" name="cvc2" minlength="3" maxlength="3" placeholder="CVC" [(ngModel)]="paymentCard.cvc2" [disabled]="isBusy" pattern="\d{3}" required />
            <md-hint *ngIf="cvc2.errors && (cvc2.touched || submitted)" class="validation-result">
                <span [hidden]="!cvc2.errors.required && cvc2.dirty">
                    CVC is required.
                </span>
                <span [hidden]="!cvc2.errors.minlength && !cvc2.errors.maxlength && !cvc2.errors.pattern">
                    CVC must be 3 numbers.
                </span>
            </md-hint>
        </md-input-container>
...
<button type="submit" md-raised-button color="primary" (click)="confirm($event, paymentCardForm.value)" [disabled]="isBusy || !paymentCardForm.valid">Confirm</button>
</form>

1)

select *
from employee em
where CONCAT(em.firstname, ' ', em.lastname) like '%parth pa%';

2)

select *
from employee em
where CONCAT_ws('-', em.firstname, em.lastname) like '%parth-pa%';

First is usefull when we have data like : 'firstname lastname'.

e.g

• parth patel
• parth p
• patel parth

Second is usefull when we have data like : 'firstname-lastname'. In it you can also use special characters.

e.g

• parth-patel
• parth_p
• patel#parth

On top of what @wisekiddo said, you can also modify your build settings in the project.pbxproj file by setting the Swift 3 @obj Inference to default like SWIFT_SWIFT3_OBJC_INFERENCE = Default; for your build flavors (i.e. debug and release), especially if you're coming from some other environment besides Xcode

You can use pageshow event to handle situation when browser navigates to your page through history traversal:

window.addEventListener( "pageshow", function ( event ) {
  var historyTraversal = event.persisted || 
                         ( typeof window.performance != "undefined" && 
                              window.performance.navigation.type === 2 );
  if ( historyTraversal ) {
    // Handle page restore.
    window.location.reload();
  }
});

Note that HTTP cache may be involved too. You need to set proper cache related HTTP headers on server to cache only those resources that need to be cached. You can also do forced reload to instuct browser to ignore HTTP cache: window.location.reload( true ). But I don't think that it is best solution.

For more information check:

• Working with BFCache article on MDN
• WebKit Page Cache II – The unload Event by Brady Eidson
• pageshow event reference on MDN
• Ajax, back button and DOM updates question
• JavaScript - bfcache/pageshow event - event.persisted always set to false? question

(this answer was added to provide shorter and more generic examples to the question - without including all the case-specific details in the original question).

There are two distinct "problems" here, the first is if a table or subquery has no rows, the second is if there are NULL values in the query.

For all versions I've tested, postgres and mysql will ignore all NULL values when averaging, and it will return NULL if there is nothing to average over. This generally makes sense, as NULL is to be considered "unknown". If you want to override this you can use coalesce (as suggested by Luc M).

$ create table foo (bar int);
CREATE TABLE

$ select avg(bar) from foo;
 avg 
-----

(1 row)

$ select coalesce(avg(bar), 0) from foo;
 coalesce 
----------
        0
(1 row)

$ insert into foo values (3);
INSERT 0 1
$ insert into foo values (9);
INSERT 0 1
$ insert into foo values (NULL);
INSERT 0 1
$ select coalesce(avg(bar), 0) from foo;
      coalesce      
--------------------
 6.0000000000000000
(1 row)

of course, "from foo" can be replaced by "from (... any complicated logic here ...) as foo"

Now, should the NULL row in the table be counted as 0? Then coalesce has to be used inside the avg call.

$ select coalesce(avg(coalesce(bar, 0)), 0) from foo;
      coalesce      
--------------------
 4.0000000000000000
(1 row)

You can rename the directory using the file system. Then you can do git rm <old directory> and git add <new directory> (Help page). Then you can commit and push.

Git will detect that the contents are the same and that it's just a rename operation, and it'll appear as a rename entry in the history. You can check that this is the case before the commit using git status

Here is a noise-free version of the solution which is to use with_items:

- name: add lines
  lineinfile: 
    dest: fruits.txt
    line: '{{ item }}'
  with_items:
    - 'Orange'
    - 'Apple'
    - 'Banana' 

For each item, if the item exists in fruits.txt no action is taken.

If the item does not exist it will be appended to the end of the file.

Easy-peasy.

Using the luxon.js library, same can be achieved using startOf and endOf methods by passing the 'day' as parameter

var DateTime = luxon.DateTime;
DateTime.local().startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z
DateTime.local().endOf('day').toUTC().toISO(); //2017-11-17T18:29:59.999Z
DateTime.fromISO(new Date().toISOString()).startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z

remove .toUTC() if you need only the local time

and you may ask why not moment.js, answer is here for that.

I would add an android:onClick to the layout and then change the layout in the activity.

So in the layout

<ImageView
(Other things like source etc.)
android:onClick="changelayout"
/>

Then in the activity add the following:

public void changelayout(View view){
    setContentView(R.layout.second_layout);
}

For arrays you can use: Array.FindIndex<T>:

int keyIndex = Array.FindIndex(words, w => w.IsKey);

For lists you can use List<T>.FindIndex:

int keyIndex = words.FindIndex(w => w.IsKey);

You can also write a generic extension method that works for any Enumerable<T>:

///<summary>Finds the index of the first item matching an expression in an enumerable.</summary>
///<param name="items">The enumerable to search.</param>
///<param name="predicate">The expression to test the items against.</param>
///<returns>The index of the first matching item, or -1 if no items match.</returns>
public static int FindIndex<T>(this IEnumerable<T> items, Func<T, bool> predicate) {
    if (items == null) throw new ArgumentNullException("items");
    if (predicate == null) throw new ArgumentNullException("predicate");

    int retVal = 0;
    foreach (var item in items) {
        if (predicate(item)) return retVal;
        retVal++;
    }
    return -1;
}

And you can use LINQ as well:

int keyIndex = words
    .Select((v, i) => new {Word = v, Index = i})
    .FirstOrDefault(x => x.Word.IsKey)?.Index ?? -1;

<h1><span style="font-weight:bold;">THIS IS</span> A HEADLINE</h1>

But be sure that h1 is marked with

font-weight:normal;

You can also set the style with a id or class attribute.

If you want to add a row into the tbody, get a reference to it and call its insertRow method.

var tbodyRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];

// Insert a row at the end of table
var newRow = tbodyRef.insertRow();

// Insert a cell at the end of the row
var newCell = newRow.insertCell();

// Append a text node to the cell
var newText = document.createTextNode('new row');
newCell.appendChild(newText);

<table id="myTable">
  <thead>
    <tr>
      <th>My Header</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>initial row</td>
    </tr>
  </tbody>
  <tfoot>
    <tr>
      <td>My Footer</td>
    </tr>
  </tfoot>
</table>

(old demo on JSFiddle)

to make UITableView sections header not sticky or sticky:

1. change the table view's style - make it grouped for not sticky & make it plain for sticky section headers - do not forget: you can do it from storyboard without writing code. (click on your table view and change it is style from the right Side/ component menu)

2. if you have extra components such as custom views or etc. please check the table view's margins to create appropriate design. (such as height of header for sections & height of cell at index path, sections)

I had this problem for over 6 months, it may be the same issue. Main symptom is that you can't move the cursor or select text in text inputs, only the arrow keys allow you to move around in the input field. Very annoying problem, especially for textarea input fields. I have this html that gets populated with 1 out of 100s of forms via Javascript:

<div class="dialog" id="alert" draggable="true">
    <div id="head" class="dialog_head">
        <img id='icon' src='images/icon.png' height=20 width=20><img id='icon_name' src='images/icon_name.png' height=15><img id='alert_close_button' class='close_button' src='images/close.png'>
    </div>
    <div id="type" class="type"></div>
    <div class='scroll_div'>
        <div id="spinner" class="spinner"></div>
        <div id="msg" class="msg"></div>
        <div id="form" class="form"></div>
    </div>
</div>

Apparently 6 months ago I had tried to make the popup draggable and failed, breaking text inputs at the same time. Once I removed draggable="true" it works again!

I just upgraded a WXWindows project to Python 2.7 and had no end of trouble getting Pydev to recognize the new interpreter. Did the same thing as above configuring the interpreter, made a fresh install of Eclipse and Pydev. Thought some part of python must have been corrupt, so I re-installed everything again. Arghh! Closed and reopened the project, and restarted Eclipse between all of these changes.

FINALLY noticed you can 'remove the PyDev project config' by right clicking on project. Then it can be made into a PyDev project again, now it is good as gold!

Couple of points:

• I believe git stash + git stash drop could be replaced with git reset --hard

• ... or, even shorter, add -f to checkout command:

  git checkout -f -b $branch
  

  That will discard any local changes, just as if git reset --hard was used prior to checkout.

As for the main question: instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

The following will work independent of your database privileges:

select * from all_triggers
where table_name = 'YOUR_TABLE'

The following alternate options may or may not work depending on your assigned database privileges:

select * from DBA_TRIGGERS

or

select * from USER_TRIGGERS

There are no gotchas. The default construction of std::string is "". But you cannot compare a string to NULL. The closest you can get is to check whether the string is empty or not, using the std::string::empty method..

For performance reasons, please do not use recursion. It would be disastrous.

def fact(n, total=1):
    while True:
        if n == 1:
            return total
        n, total = n - 1, total * n

Check running results

cProfile.run('fact(126000)')

4 function calls in 5.164 seconds

Using the stack is convenient(like recursive call), but it comes at a cost: storing detailed information can take up a lot of memory.

If the stack is high, it means that the computer stores a lot of information about function calls.

The method only takes up constant memory(like iteration).

Or Using for loop

def fact(n):
    result = 1
    for i in range(2, n + 1):
        result *= i
    return result

Check running results

cProfile.run('fact(126000)')

4 function calls in 4.708 seconds

Or Using builtin function math

def fact(n):
    return math.factorial(n)

Check running results

cProfile.run('fact(126000)')

5 function calls in 0.272 seconds

Use jQuery

Look how easy it would be if you did.

Example:

$('#td1').html('hello world');

This function is used to clear all the elements in the form including radio button, check-box, select, multiple select, password, text, textarea, file.

function clear_form_elements(class_name) {
  jQuery("."+class_name).find(':input').each(function() {
    switch(this.type) {
        case 'password':
        case 'text':
        case 'textarea':
        case 'file':
        case 'select-one':
        case 'select-multiple':
        case 'date':
        case 'number':
        case 'tel':
        case 'email':
            jQuery(this).val('');
            break;
        case 'checkbox':
        case 'radio':
            this.checked = false;
            break;
    }
  });
}

To change the panel's background color, use the following code:

myplot + theme(panel.background = element_rect(fill = 'green', colour = 'red'))

To change the color of the plot (but not the color of the panel), you can do:

myplot + theme(plot.background = element_rect(fill = 'green', colour = 'red'))

See here for more theme details Quick reference sheet for legends, axes and themes.

You can use MinMaxPriorityQueue (it's a part of the Guava library): here's the documentation. Instead of poll(), you need to call the pollLast() method.

Use In instead of =

 select * from dbo.books
 where isbn in (select isbn from dbo.lending 
                where act between @fdate and @tdate
                and stat ='close'
               )

or you can use Exists

SELECT t1.*,t2.*
FROM  books   t1 
WHERE  EXISTS ( SELECT * FROM dbo.lending t2 WHERE t1.isbn = t2.isbn and
                t2.act between @fdate and @tdate and t2.stat ='close' )

Slightly off topic but could be very useful as it could be the basis for other tasks you might want to do with simulators.

I like to keep my simulator list to a minimum, and since there is no multi-select in the "Devices and Simulators" it is a pain to delete them all.

So I boot all the sims that I want to use then, remove all the simulators that I don't have booted.

Delete all the shutdown simulators:

xcrun simctl list | grep -w "Shutdown"  | grep -o "([-A-Z0-9]*)" | sed 's/[\(\)]//g' | xargs -I uuid xcrun simctl delete  uuid

If you need individual simulators back, just add them back to the list in "Devices and Simulators" with the plus button.

After running the command sudo mysql_secure_installation.

1. Run sudo mysql to enter into the mysql prompt.
2. Run this SELECT user,authentication_string,plugin,host FROM mysql.user; to check for user root to have as plugin auth_socket.
3. Then do run uninstall plugin validate_password; to drop priviledges before running this ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';Be sure to change password to a strong password.

distinct is not a function. It always operates on all columns of the select list.

Your problem is a typical "greatest N per group" problem which can easily be solved using a window function:

select ...
from (
  select IDNo,
         FirstName,
         LastName,
         ....,
         row_number() over (partition by lower(idno) order by firstname) as rn 
  from people 
) t
where rn = 1;

Using the order by clause you can select which of the duplicates you want to pick.

The above can be used in a left join, see below:

select ...
from x
  left join (
    select IDNo,
           FirstName,
           LastName,
           ....,
           row_number() over (partition by lower(idno) order by firstname) as rn 
    from people 
  ) p on p.idno = x.idno and p.rn = 1
where ...

You can't divide IF/ELSE instructions into two separate blocks. If you need HTML code to be printed, use echo.

<html>
    <?php
        function login()
        {
            // Login function code
        }
        if (login())
        {
            echo "<h2>Welcome Administrator</h2>
            <a href=\"upload.php\">Upload Files</a>
            <br />
            <a href=\"points.php\">Edit Points Tally</a>";
        }
        else
        {
            echo "Incorrect login details. Please login";
        }
    ?>

On Windows,Close all the SQL Developer windows. Then You need to completely delete the SQL Developer and sqldeveloper folders located in user/AppData/Roaming. Finally, run the program, you will be prompted for new JDK.

Note that AppData is a hidden folder.

If you are using the debug apk, the key that is used to sign it is in

C:\Users\<user>\.android\debug.keystore

If you use that same key, there should not be a conflict when installing.

mainWB.Sheets.Add(After:=Sheets(Sheets.Count)).Name = new_sheet_name 

should probably be

mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name 

Perhaps this is specific to .net core, I found DisplayName would not work but Display(Name=...) does. This may save someone else the troubleshooting involved :)

No need for css, you can just use the HR tag from HTML

<hr />

NOTE: This advice is now out-dated as per comment since Git 1.6.1. Git used to behave this way, and no longer does.

Git by default attempts to store symlinks instead of following them (for compactness, and it's generally what people want).

However, I accidentally managed to get it to add files beyond the symlink when the symlink is a directory.

I.e.:

  /foo/
  /foo/baz
  /bar/foo --> /foo
  /bar/foo/baz

by doing

 git add /bar/foo/baz

it appeared to work when I tried it. That behavior was however unwanted by me at the time, so I can't give you information beyond that.

You could set the @Input on the setter directly, as described below:

_allowDay: boolean;
get allowDay(): boolean {
    return this._allowDay;
}
@Input() set allowDay(value: boolean) {
    this._allowDay = value;
    this.updatePeriodTypes();
}

See this Plunkr: https://plnkr.co/edit/6miSutgTe9sfEMCb8N4p?p=preview.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

it seems you can use @json($leads) since laravel 5.5

https://laravel.com/docs/5.5/blade

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

In case you need to do it in one line command with bash script as below:

$ cd /path/to/your/repo && /bin/bash $HOME/remove_submodule.sh /path/to/the/submodule

Create bash script file in the $HOME dir named i.e. remove_submodule.sh:

#!/bin/bash

git config -f .gitmodules --remove-section submodule.$1
git config -f .git/config --remove-section submodule.$1
git rm --cached $1
git add .gitmodules
git commit -m "Remove submodule in $1"
rm -rf $1
rm -rf .git/modules/$1
git push origin $(git rev-parse --abbrev-ref HEAD) --force --quiet

Since x!=x returns the same boolean array with np.isnan(x) (because np.nan!=np.nan would return True), you could also write:

np.argwhere(x!=x)

However, I still recommend writing np.argwhere(np.isnan(x)) since it is more readable. I just try to provide another way to write the code in this answer.

I fixed it by deleting the hidden .svn folder and replaced it with the fresh checkout .svn and it worked. Probably this hidden folder got messed up!

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);
})
.listen(2000);

This worked for me:

window.location.replace(window.location.pathname)

If you just use rm, you will need to follow it up with git add <fileRemoved>. git rm does this in one step.

You can also use git rm --cached which will remove the file from the index (staging it for deletion on the next commit), but keep your copy in the local file system.

For future people CTRL+ALT+D or just view > report data in ancient ssrs 2008 VS BI. In newer 2017 SSRS, it's still the same. Funny how they change a bunch of things around, yet kept this the same.

The problem is quite simple. You checked if the version was less than 2.4, not less than or equal to. So if the Python version is 2.4, it's not less than 2.4. What you should have had was:

    if sys.version_info **<=** (2, 4):

, not

    if sys.version_info < (2, 4):

They are the same, but in C++ there's a good reason to always use const on the right. You'll be consistent everywhere because const member functions must be declared this way:

int getInt() const;

It changes the this pointer in the function from Foo * const to Foo const * const. See here.

Actually you can do it.

Although, someone should note that repeating the CASE statements are not bad as it seems. SQL Server's query optimizer is smart enough to not execute the CASE twice so that you won't get any performance hit because of that.

Additionally, someone might use the following logic to not repeat the CASE (if it suits you..)

INSERT INTO dbo.T1
(
    Col1,
    Col2,
    Col3
)
SELECT
    1,
    SUBSTRING(MyCase.MergedColumns, 0, CHARINDEX('%', MyCase.MergedColumns)),
    SUBSTRING(MyCase.MergedColumns, CHARINDEX('%', MyCase.MergedColumns) + 1, LEN(MyCase.MergedColumns) - CHARINDEX('%', MyCase.MergedColumns))
FROM
    dbo.T1 t
LEFT OUTER JOIN
(
    SELECT CASE WHEN 1 = 1 THEN '2%3' END MergedColumns
) AS MyCase ON 1 = 1

This will insert the values (1, 2, 3) for each record in the table T1. This uses a delimiter '%' to split the merged columns. You can write your own split function depending on your needs (e.g. for handling null records or using complex delimiter for varchar fields etc.). But the main logic is that you should join the CASE statement and select from the result set of the join with using a split logic.

Sometimes you have to remove the current options in order to manipulate the selected options.

Here is an example how to set options:

<select id="mySelectId" class="chosen-select" multiple="multiple">
  <option value=""></option>
  <option value="Argentina">Argentina</option>
  <option value="Germany">Germany</option>
  <option value="Greece">Greece</option>
  <option value="Japan">Japan</option>
  <option value="Thailand">Thailand</option>
</select>

<script>
activateChosen($('body'));
selectChosenOptions($('#mySelectId'), ['Argentina', 'Germany']);

function activateChosen($container, param) {
    param = param || {};
    $container.find('.chosen-select:visible').chosen(param);
    $container.find('.chosen-select').trigger("chosen:updated");
}

function selectChosenOptions($select, values) {
    $select.val(null);                                  //delete current options
    $select.val(values);                                //add new options
    $select.trigger('chosen:updated');
}
</script>

For people who have come here to look for a general answer for duplicate row removal, use !duplicated():

a <- c(rep("A", 3), rep("B", 3), rep("C",2))
b <- c(1,1,2,4,1,1,2,2)
df <-data.frame(a,b)

duplicated(df)
[1] FALSE  TRUE FALSE FALSE FALSE  TRUE FALSE  TRUE

> df[duplicated(df), ]
  a b
2 A 1
6 B 1
8 C 2

> df[!duplicated(df), ]
  a b
1 A 1
3 A 2
4 B 4
5 B 1
7 C 2

Answer from: Removing duplicated rows from R data frame

Yes there is something similar to pointers in PHP but may not match with what exactly happens in c or c++. Following is one of the example.

$a = "test";
$b = "a";
echo $a;
echo $b;
echo $$b;

//output
test
a
test

This illustrates similar concept of pointers in PHP.

To summarize the other answers, for general use:

Multi-line if...then statement

if [ foo ]; then
    a; b
elif [ bar ]; then
    c; d
else
    e; f
fi

Single-line version

if [ foo ]; then a && b; elif [ bar ]; c && d; else e && f; fi

Using the OR operator

( foo && a && b ) || ( bar && c && d ) || e && f;

Notes

Remember that the AND and OR operators evaluate whether or not the result code of the previous operation was equal to true/success (0). So if a custom function returns something else (or nothing at all), you may run into problems with the AND/OR shorthand. In such cases, you may want to replace something like ( a && b ) with ( [ a == 'EXPECTEDRESULT' ] && b ), etc.

Also note that ( and [ are technically commands, so whitespace is required around them.

Instead of a group of && statements like then a && b; else, you could also run statements in a subshell like then $( a; b ); else, though this is less efficient. The same is true for doing something like result1=$( foo; a; b ); result2=$( bar; c; d ); [ "$result1" -o "$result2" ] instead of ( foo && a && b ) || ( bar && c && d ). Though at that point you'd be getting more into less-compact, multi-line stuff anyway.

static class Constants
{
    public const int MIN_LENGTH = 5;
    public const int MIN_WIDTH  = 5; 
    public const int MIN_HEIGHT = 6;

{
    length = Constants.MIN_LENGTH; 
    width  = Constants.MIN_WIDTH; 
    height = Constants.MIN_HEIGHT;  
}

I Think I can improve on this answer. Try this:

The parameter 'Pranks' is a CSV. ie. '1,2,3,4.....etc'

CREATE PROCEDURE AddRanks(
IN Pranks TEXT
)
BEGIN
  DECLARE VCounter INTEGER;
  DECLARE VStringToAdd VARCHAR(50);
  SET VCounter = 0;
  START TRANSACTION;
  REPEAT
    SET VStringToAdd = (SELECT TRIM(SUBSTRING_INDEX(Pranks, ',', 1)));
    SET Pranks = (SELECT RIGHT(Pranks, TRIM(LENGTH(Pranks) - LENGTH(SUBSTRING_INDEX(Pranks, ',', 1))-1)));
    INSERT INTO tbl_rank_names(rank)
    VALUES(VStringToAdd);
    SET VCounter = VCounter + 1;
  UNTIL (Pranks = '')
  END REPEAT;
  SELECT VCounter AS 'Records added';
  COMMIT;
END;

This method makes the searched string of CSV values progressively shorter with each iteration of the loop, which I believe would be better for optimization.

my quick answer with basic java arithmetic calculation is this:

First consider the following values:

1 Minute = 60 Seconds
1 Hour = 3600 Seconds ( 60 * 60 )
1 Day = 86400 Second ( 24 * 3600 )

1. First divide the input by 86400, if you you can get a number greater than 0 , this is the number of days. 2.Again divide the remained number you get from the first calculation by 3600, this will give you the number of hours
2. Then divide the remainder of your second calculation by 60 which is the number of Minutes
3. Finally the remained number from your third calculation is the number of seconds

the code snippet is as follows:

int input=500000;
int numberOfDays;
int numberOfHours;
int numberOfMinutes;
int numberOfSeconds;

numberOfDays = input / 86400;
numberOfHours = (input % 86400 ) / 3600 ;
numberOfMinutes = ((input % 86400 ) % 3600 ) / 60 
numberOfSeconds = ((input % 86400 ) % 3600 ) % 60  ;

I hope to be helpful to you.

Bootstrap v4 Solution - jQuery based, but better than a pure css solution

This ensures that you can still follow top level link clicks and is compatible with mobile.

This was built with desktop and mobile in mind. Fell free to wrap the jQuery with a conditional that checks if the window width is greater than 768px.

jQuery

/** Dropdown on hover */
$(".nav-link.dropdown-toggle").hover( function () {
    // Open up the dropdown
    $(this).removeAttr('data-toggle'); // remove the data-toggle attribute so we can click and follow link
    $(this).parent().addClass('show'); // add the class show to the li parent
    $(this).next().addClass('show'); // add the class show to the dropdown div sibling
}, function () {
    // on mouseout check to see if hovering over the dropdown or the link still
    var isDropdownHovered = $(this).next().filter(":hover").length; // check the dropdown for hover - returns true of false
    var isThisHovered = $(this).filter(":hover").length;  // check the top level item for hover
    if(isDropdownHovered || isThisHovered) {
        // still hovering over the link or the dropdown
    } else {
        // no longer hovering over either - lets remove the 'show' classes
        $(this).attr('data-toggle', 'dropdown'); // put back the data-toggle attr
        $(this).parent().removeClass('show');
        $(this).next().removeClass('show');
    }
});
// Check the dropdown on hover
$(".dropdown-menu").hover( function () {
}, function() {
    var isDropdownHovered = $(this).prev().filter(":hover").length; // check the dropdown for hover - returns true of false
    var isThisHovered= $(this).filter(":hover").length;  // check the top level item for hover
    if(isDropdownHovered || isThisHovered) {
        // do nothing - hovering over the dropdown of the top level link
    } else {
        // get rid of the classes showing it
        $(this).parent().removeClass('show');
        $(this).removeClass('show');
    }
});

CSS

@media(min-width:  768px) {
  .dropdown-menu {
    margin-top: 0; // fixes closing on slow mouse transition
  }
}

You can have many constructors as long as they take in different parameters. But the compiler putting a default constructor in is not called "constructor overriding".

Temporarily adjust the font size

Go to Settings (or Preferences in Mac) > Editor > General > Change font size (Zoom) with Ctrl+Mouse Wheel OR Press "Cmd+Shift+A" for mac.

This will allow you to quickly modify the font size whenever you want. However, the font will get reset to the default size the next time you start Android Studio. (The Control+Mouse Wheel functionality will not get reset, though. You only need to do this once.)

Permanently change the default font size

Go to Settings > Editor > Colors & Fonts > Font. Click "Save As..." and choose a new scheme name. Then change the font size and say OK. This will be the default size every time you open Android Studio now.

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

If you're using .NET 3.5 SP1+ the better way to do this is to take a look at the

System.DirectoryServices.AccountManagement namespace.

It has methods to find people and you can pretty much pass in any username format you want and then returns back most of the basic information you would need. If you need help on loading the more complex objects and properties check out the source code for http://umanage.codeplex.com its got it all.

My Oracle is a bit rusty, but I think this would work:

SELECT * FROM TableA
WHERE ROWID IN ( SELECT MAX(ROWID) FROM TableA GROUP BY Language )

When your function is deterministic, you are safe to declare it to be deterministic. The location of "DETERMINISTIC" keyword is as follows.

Reading CSV format description makes me feel that using 3rd party library would be less headache than writing it myself:

• http://en.wikipedia.org/wiki/Comma-separated_values

Wikipedia lists 10 or something known libraries:

• http://en.wikipedia.org/wiki/CSV_application_support

I compared libs listed using some kind of check list. OpenCSV turned out a winner to me (YMMV) with the following results:

+ maven

+ maven - release version   // had some cryptic issues at _Hudson_ with snapshot references => prefer to be on a safe side

+ code examples

+ open source   // as in "can hack myself if needed"

+ understandable javadoc   // as opposed to eg javadocs of _genjava gj-csv_

+ compact API   // YAGNI (note *flatpack* seems to have much richer API than OpenCSV)

- reference to specification used   // I really like it when people can explain what they're doing

- reference to _RFC 4180_ support   // would qualify as simplest form of specification to me

- releases changelog   // absence is quite a pity, given how simple it'd be to get with maven-changes-plugin   // _flatpack_, for comparison, has quite helpful changelog

+ bug tracking

+ active   // as in "can submit a bug and expect a fixed release soon"

+ positive feedback   // Recommended By 51 users at sourceforge (as of now)

It's simple with some flex and overflow set to hidden.

I stumbled on this question because I want to use node.js with visual studio 2015 on my new computer with windows 10. I used node.js on windows 7 and 8 and 8.1 Never a problem node.js finding a module. I use a legacy node.js 0.10.39 because I have to use this version because of the serial and RFXCOM module.

The answer for windows 10 is to set the NODE_PATH in the enviroment variables with C:\Users\User\node_modules.

I am no expert at this (and this page was very helpful along with http://mywiki.wooledge.org/UsingFind)

Just noticed -path is for a path that fully matches the string/path that comes just after find (. in theses examples) where as -name matches all basenames.

find . -path ./.git  -prune -o -name file  -print

blocks the .git directory in your current directory ( as your finding in . )

find . -name .git  -prune -o -name file  -print

blocks all .git subdirectories recursively.

Note the ./ is extremely important!! -path must match a path anchored to . or whatever comes just after find if you get matches with out it (from the other side of the or '-o') there probably not being pruned! I was naively unaware of this and it put me of using -path when it is great when you don't want to prune all subdirectory with the same basename :D

Edit: as @aix suggested, a better (more fair) way to compare the speed difference:

In [1]: %timeit abs(5)
10000000 loops, best of 3: 86.5 ns per loop

In [2]: from math import fabs

In [3]: %timeit fabs(5)
10000000 loops, best of 3: 115 ns per loop

In [4]: %timeit abs(-5)
10000000 loops, best of 3: 88.3 ns per loop

In [5]: %timeit fabs(-5)
10000000 loops, best of 3: 114 ns per loop

In [6]: %timeit abs(5.0)
10000000 loops, best of 3: 92.5 ns per loop

In [7]: %timeit fabs(5.0)
10000000 loops, best of 3: 93.2 ns per loop

In [8]: %timeit abs(-5.0)
10000000 loops, best of 3: 91.8 ns per loop

In [9]: %timeit fabs(-5.0)
10000000 loops, best of 3: 91 ns per loop

So it seems abs() only has slight speed advantage over fabs() for integers. For floats, abs() and fabs() demonstrate similar speed.

In addition to what @aix has said, one more thing to consider is the speed difference:

In [1]: %timeit abs(-5)
10000000 loops, best of 3: 102 ns per loop

In [2]: import math

In [3]: %timeit math.fabs(-5)
10000000 loops, best of 3: 194 ns per loop

So abs() is faster than math.fabs().

There is no difference. The $_SERVER['PHP_SELF'] just makes the execution time slower by like 0.000001 second.

You can use the datedif function to find out difference in days.

=DATEDIF(A1,TODAY(),"d")

Quote from excel.datedif.com

The mysterious datedif function in Microsoft Excel

The Datedif function is used to calculate interval between two dates in days, months or years.

This function is available in all versions of Excel but is not documented. It is not even listed in the "Insert Function" dialog box. Hence it must be typed manually in the formula box. Syntax

DATEDIF( start_date, end_date, interval_unit )

start_date from date end_date to date (must be after start_date) interval_unit Unit to be used for output interval Values for interval_unit

interval_unit Description

D Number of days

M Number of complete months

Y Number of complete years

YD Number of days excluding years

MD Number of days excluding months and years

YM Number of months excluding years

Errors

Error Description

#NUM! The end_date is later than (greater than) the start_date or interval_unit has an invalid value. #VALUE! end_date or start_date is invalid.

Perhaps the simplest way to solve this (that will work) is:

• CREATE new_table AS SELECT id, col1, col2, ... (only the columns you actually want in the final table) FROM my_table;

• RENAME my_table TO old_table, new_table TO my_table;

• DROP old_table;

Or keep old_table for a rollback if needed.

This will work but foreign keys will not be moved. You would have to re-add them to my_table later; also foreign keys in other tables that reference my_table will have to be fixed (pointed to the new my_table).

Good Luck...

Try the following :)

        textBox1.Multiline = true;
        textBox1.Height = 100;
        textBox1.Width = 173;

"N/A" is a string and cannot be converted to a number. Catch the exception and handle it. For example:

    String text = "N/A";
    int intVal = 0;
    try {
        intVal = Integer.parseInt(text);
    } catch (NumberFormatException e) {
        //Log it if needed
        intVal = //default fallback value;
    }

After much further research, i managed to find a solution.

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});

function placeMarker(location) {
    var marker = new google.maps.Marker({
        position: location, 
        map: map
    });
}

<a href="#" style="text-decoration:none !important; text-decoration:none;">BOOK NOW</a>

Outlook will strip out the style with !important tag leaving the regular style, thus no underline. The !important tag will over rule the web based email clients' default style, thus leaving no underline.

There is small and useful library designed for this purposes:

dependencies {
    compile 'com.shamanland:fonticon:0.1.9'
}

Get demo on Google Play.

You can easily add font-based icon in your layout:

<com.shamanland.fonticon.FontIconView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/ic_android"
    android:textSize="@dimen/icon_size"
    android:textColor="@color/icon_color"
    />

You can inflate font-icon as Drawable from xml:

<?xml version="1.0" encoding="utf-8"?>
<font-icon
    xmlns:android="http://schemas.android.com/apk/res-auto"
    android:text="@string/ic_android"
    android:textSize="@dimen/big_icon_size"
    android:textColor="@color/green_170"
    />

Java code:

Drawable icon = FontIconDrawable.inflate(getResources(), R.xml.ic_android);

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.

But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.

I've been playing with this same feature and found out that FF, IE, Chrome and Opera have the ability to provide the source element of an event. I haven't tested Safari but my guess is it might have something similar.

$('#Form').keyup(function (e) {
    var ctrl = null;
    if (e.originalEvent.explicitOriginalTarget) { // FF
        ctrl = e.originalEvent.explicitOriginalTarget;
    }
    else if (e.originalEvent.srcElement) { // IE, Chrome and Opera
        ctrl = e.originalEvent.srcElement;
    }
    //...
});

import { APP_BASE_HREF } from '@angular/common';
import { NgModule } from '@angular/core';

@NgModule({
    providers: [
        {
            provide: APP_BASE_HREF,
            useValue: '/' + (window.location.pathname.split('/')[1] || '')
        }

export class AppModule { }

You do not have to specify a base tag in your index.html, if you are providing value for APP_BASE_HREF opaque token.

I have JSONObject like this: {"status":[{"Response":"success"}]}.

If I want to convert the JSONObject value, which is a JSONArray into JSONObject automatically without using any static value, here is the code for that.

JSONArray array=new JSONArray();
JSONObject obj2=new JSONObject();
obj2.put("Response", "success");
array.put(obj2);
JSONObject obj=new JSONObject();
obj.put("status",array);

Converting the JSONArray to JSON Object:

Iterator<String> it=obj.keys();
        while(it.hasNext()){
String keys=it.next();
JSONObject innerJson=new JSONObject(obj.toString());
JSONArray innerArray=innerJson.getJSONArray(keys);
for(int i=0;i<innerArray.length();i++){
JSONObject innInnerObj=innerArray.getJSONObject(i);
Iterator<String> InnerIterator=innInnerObj.keys();
while(InnerIterator.hasNext()){
System.out.println("InnInnerObject value is :"+innInnerObj.get(InnerIterator.next()));


 }
}

There are several problems in your code.

First the big ones:

1. You are creating a new figure and a new axes in every iteration of your loop ? put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop.

2. Don't use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords.

3. With plt.axes() you are creating a new axes again. Use ax.set_aspect('equal').

The minor things: You should not mix the MATLAB-like syntax like plt.axis() with the objective syntax. Use ax.set_xlim(a,b) and ax.set_ylim(a,b)

This should be a working minimal example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)

# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)

ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)

# And a corresponding grid
ax.grid(which='both')

# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)

plt.show()

Output is this:

I usually use selectors in my main stylesheet, then make an ie6 specific .js (jquery) file that adds a class to all of the input types. Example:

$(document).ready(function(){
  $("input[type='text']").addClass('text');
)};

And then just duplicate my styles in the ie6 specific stylesheet using the classes. That way the actual markup is a little bit cleaner.

It may not be the elegant way but you can iterate all classes in the assembly and invoke Type.IsSubclassOf(AbstractDataExport) for each one.

I solved this using multer as suggested above, but they missed giving a full working example, on how to do this. Basically this can happen when you have a form group with enctype="multipart/form-data". Here's the HTML for the form I had:

<form action="/stats" enctype="multipart/form-data" method="post">
  <div class="form-group">
    <input type="file" class="form-control-file" name="uploaded_file">
    <input type="text" class="form-control" placeholder="Number of speakers" name="nspeakers">
    <input type="submit" value="Get me the stats!" class="btn btn-default">            
  </div>
</form>

And here's how to use multer to get the values and names of this form with Express.js and node.js:

var multer  = require('multer')
var upload = multer({ dest: './public/data/uploads/' })
app.post('/stats', upload.single('uploaded_file'), function (req, res) {
   // req.file is the name of your file in the form above, here 'uploaded_file'
   // req.body will hold the text fields, if there were any 
   console.log(req.file, req.body)
});

To make it easier for yourself you could also create an actionfilterattribute

public class AllowJsonGetAttribute : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var jsonResult = filterContext.Result as JsonResult;

        if (jsonResult == null)
            throw new ArgumentException("Action does not return a JsonResult, 
                                                   attribute AllowJsonGet is not allowed");

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;            

        base.OnResultExecuting(filterContext);
    }
}

and use it on your action

[AllowJsonGet]
public JsonResult MyAjaxAction()
{
    return Json("this is my test");
}

If you have a single argument passed in the URL you can do it as follows

from flask import request
#url
http://10.1.1.1:5000/login/alex

from flask import request
@app.route('/login/<username>', methods=['GET'])
def login(username):
    print(username)

In case you have multiple parameters:

#url
http://10.1.1.1:5000/login?username=alex&password=pw1

from flask import request
@app.route('/login', methods=['GET'])
    def login():
        username = request.args.get('username')
        print(username)
        password= request.args.get('password')
        print(password)

What you were trying to do works in case of POST requests where parameters are passed as form parameters and do not appear in the URL. In case you are actually developing a login API, it is advisable you use POST request rather than GET and expose the data to the user.

In case of post request, it would work as follows:

#url
http://10.1.1.1:5000/login

HTML snippet:

<form action="http://10.1.1.1:5000/login" method="POST">
  Username : <input type="text" name="username"><br>
  Password : <input type="password" name="password"><br>
  <input type="submit" value="submit">
</form>

Route:

from flask import request
@app.route('/login', methods=['POST'])
    def login():
        username = request.form.get('username')
        print(username)
        password= request.form.get('password')
        print(password)

$users = User::all();
$associates = Associate::all();

$userAndAssociate = $users->merge($associates);

This chunk should do the work:

plot(var2 ~ var1, data=subset(dataframe, var3 < 150))

My best regards.

How this works:

1. Fisrt, we make selection using the subset function. Other possibilities can be used, like, subset(dataframe, var4 =="some" & var5 > 10). The "&" operator can be used to select all "some" and over 10. Also the operator "|" could be used to select "some" or "over 10".
2. The next step is to plot the results of the subset, using tilde (~) operator, that just imply a formula, in this case var.response ~ var.independet. Of course this is not a formula, but works great for this case.

The EOF token must be at the beginning of the line, you can't indent it along with the block of code it goes with.

If you write <<-EOF you may indent it, but it must be indented with Tab characters, not spaces. So it still might not end up even with the block of code.

Also make sure you have no whitespace after the EOF token on the line.

i solved same problem like this:

• delete old migration file
• update-database -force
• Add-Migration AddedEntity
• update-database

public static class ErrorCode
{
    public const IDictionary<string , string > m_ErrorCodeDic;

    public static ErrorCode()
    {
      m_ErrorCodeDic = new Dictionary<string, string>()
             { {"1","User name or password problem"} };             
    }
}

Probably initialise in the constructor.

I made a script to solve this which is here. You don't need any extra software for this. Installation:
brew install akashaggarwal7/tools/tsay
Usage:
sleep 5; tsay

Feel free to contribute!

As an alternative to the other answers, it's possible to do this with a syntax similar to the way you originally intended if you do it via a case statement rather than an if:

session := Session{}
switch {
case Session{} == session:
    fmt.Println("zero")
default:
    fmt.Println("not zero")
}

playground example

In the second .c file use extern keyword with the same variable name.

.a files are usually libraries which get statically linked (or more accurately archives), and
.so are dynamically linked libraries.

To do a port you will need the source code that was compiled to make them, or equivalent files on your AIX machine.

Python 2.x:

print '-' * 3

Python 3.x:

print('-' * 3)

An alternative to 'LOAD DATA' is available in which the data will not be moved from your existing source location to hive data warehouse location.

You can use ALTER TABLE command with 'LOCATION' option. Here is below required command

ALTER TABLE table_name ADD PARTITION (date_col='2017-02-07') LOCATION 'hdfs/path/to/location/'

The only condition here is, the location should be a directory instead of file.

Hope this will solve the problem.

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

If you don't want to wrap a table under any div:

table{
  table-layout: fixed;
}
tbody{
      display: block;
    overflow: auto;
}

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

have all the pages in distinct div areas

<div style="" id="page1">
First Page Contents
</div>

<div style="display:none" id="page2">
Second Page Contents
</div>

then use a js script to workout what you are viewing (like within an hashtag style) to navigate. Either that, or ajax to get the response from a specific file (like /pages/page1.html)

var $prehashval = "";
function loop()
{
    if (location.hash.slice(1)!=$prehashval)
        hashChanged();

    $prehashval = location.hash.slice(1);
    setTimeout("loop()", 100);
}
function hashChanged()
{
    var $output;
    switch (location.hash.slice(1))
    {
        case "page1":
            document.getElementById('page1').style.display = "";
            document.getElementById('page2').style.display = "none";
            break;
        case "page2":
            document.getElementById('page1').style.display = "none";
            document.getElementById('page2').style.display = "";
            break;
        default:
            $output = location.hash.slice(1);
    }
}
loop();

The best approach from the response of Khemraj:

App class

class App : Application() {

    companion object {
        lateinit var instance: Application
        lateinit var resourses: Resources
    }


    // MARK: - Lifecycle

    override fun onCreate() {
        super.onCreate()
        instance = this
        resourses = resources
    }

}

Declaration in the manifest

<application
        android:name=".App"
        ...>
</application>     

Constants class

class Localizations {

    companion object {
        val info = App.resourses.getString(R.string.info)
    }

}

Using

textView.text = Localizations.info

Basic the facebook token expires about in a hour. But you can using 'exchange' token to get a long-lived token https://developers.facebook.com/docs/facebook-login/access-tokens

GET /oauth/access_token?  
    grant_type=fb_exchange_token&           
    client_id={app-id}&
    client_secret={app-secret}&
    fb_exchange_token={short-lived-token} 

About access

<ol class="viewer-nav">
    <li *ngFor="let section of sections" 
        [attr.data-sectionvalue]="section.value"
        (click)="get_data($event)">
        {{ section.text }}
    </li>  
</ol>

And

get_data(event) {
   console.log(event.target.dataset.sectionvalue)
}

Josh is correct but he left out one variation:

ALTER ROLE <role_name> IN DATABASE <db_name> SET search_path TO schema1,schema2;

Set the search path for the user, in one particular database.

It is very straight forward

HTML

<input type="text" placeholder="some text" />
<input type="button" value="button" class="button"/>
<button class="button">Another button</button>

jQuery

$(document).ready(function(){
  $('.button').css( 'cursor', 'pointer' );

  // for old IE browsers
  $('.button').css( 'cursor', 'hand' ); 
});
