Limited CSS and jQuery Solution

I am not sure how elegant this solution is, but it cuts everything exactly in half: http://jsfiddle.net/9wxfY/11/

Otherwise, I have created a nice solution for you... All you need to do is have this for your HTML:

Take a look at this most recent, and accurate, edit as of 6/13/2016 : http://jsfiddle.net/9wxfY/43/

As for the CSS, it is very limited... You only need to apply it to :nth-child(even)

$(function(){_x000D_
  var $hc = $('.half-color');_x000D_
  var str = $hc.text();_x000D_
  $hc.html("");_x000D_
_x000D_
  var i = 0;_x000D_
  var chars;_x000D_
  var dupText;_x000D_
_x000D_
  while(i < str.length){_x000D_
    chars = str[i];_x000D_
    if(chars == " ") chars = "&nbsp;";_x000D_
    dupText = "<span>" + chars + "</span>";_x000D_
_x000D_
    var firstHalf = $(dupText);_x000D_
    var secondHalf = $(dupText);_x000D_
_x000D_
    $hc.append(firstHalf)_x000D_
    $hc.append(secondHalf)_x000D_
_x000D_
    var width = firstHalf.width()/2;_x000D_
_x000D_
    firstHalf.width(width);_x000D_
    secondHalf.css('text-indent', -width);_x000D_
_x000D_
    i++;_x000D_
  }_x000D_
});

.half-color span{_x000D_
  font-size: 2em;_x000D_
  display: inline-block;_x000D_
  overflow: hidden;_x000D_
}_x000D_
.half-color span:nth-child(even){_x000D_
  color: red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="half-color">This is a sentence</div>

That's how I would handle different images (sizes and proportions) in a flexible grid.

.images {_x000D_
  display: flex;_x000D_
  flex-wrap: wrap;_x000D_
  margin: -20px;_x000D_
}_x000D_
_x000D_
.imagewrapper {_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  width: calc(50% - 20px);_x000D_
  height: 300px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.image {_x000D_
  display: block;_x000D_
  object-fit: cover;_x000D_
  width: 100%;_x000D_
  height: 100%; /* set to 'auto' in IE11 to avoid distortions */_x000D_
}

<div class="images">_x000D_
  <div class="imagewrapper">_x000D_
    <img class="image" src="https://via.placeholder.com/800x600" />_x000D_

Alternatively if you want to persist in using the DocumentType class. Then you could just add the following annotation on top of your DocumentType class.

    @XmlRootElement(name="document")

Note: the String value "document" refers to the name of the root tag of the xml message.

As posted somewhere else, this works, too:

apt-cache madison <package_name>

Typically you could use mongoose validation but since you need an async result (db query for existing names) and validators don't support promises (from what I can tell), you will need to create your own function and pass a callback. Here is an example:

var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    ObjectId = Schema.ObjectId;

mongoose.connect('mongodb://localhost/testDB');

var UserSchema = new Schema({
    name: {type:String}
});

var UserModel = mongoose.model('UserModel',UserSchema);

function updateUser(user,cb){
    UserModel.find({name : user.name}, function (err, docs) {
        if (docs.length){
            cb('Name exists already',null);
        }else{
            user.save(function(err){
                cb(err,user);
            });
        }
    });
}

UserModel.findById(req.param('sid'),function(err,existingUser){
   if (!err && existingUser){
       existingUser.name = 'Kevin';
       updateUser(existingUser,function(err2,user){
           if (err2 || !user){
               console.log('error updated user: ',err2);
           }else{
               console.log('user updated: ',user);
           }

       });
   } 
});

UPDATE: A better way

The pre hook seems to be a more natural place to stop the save:

UserSchema.pre('save', function (next) {
    var self = this;
    UserModel.find({name : self.name}, function (err, docs) {
        if (!docs.length){
            next();
        }else{                
            console.log('user exists: ',self.name);
            next(new Error("User exists!"));
        }
    });
}) ;

UPDATE 2: Async custom validators

It looks like mongoose supports async custom validators now so that would probably be the natural solution:

    var userSchema = new Schema({
      name: {
        type: String,
        validate: {
          validator: function(v, cb) {
            User.find({name: v}, function(err,docs){
               cb(docs.length == 0);
            });
          },
          message: 'User already exists!'
        }
      }
    });

Had this issue with ES6 and TypeORM while trying to pass .where("order.id IN (:orders)", { orders }), where orders was a comma separated string of numbers. When I converted to a template literal, the problem was resolved.

.where(`order.id IN (${orders})`);

I really like the accepted answer. I believe there is yet another way to approach this as well. Let's say you have a very short list of properties that you wouldn't want to ever include in a View, so when updating the entity, those would be omitted. Let's say that those two fields are Password and SSN.

db.Users.Attach(updatedUser);

var entry = db.Entry(updatedUser);
entry.State = EntityState.Modified;

entry.Property(e => e.Password).IsModified = false;
entry.Property(e => e.SSN).IsModified = false;   

db.SaveChanges();   

This example allows you to essentially leave your business logic alone after adding a new field to your Users table and to your View.

The value 3172978990 is greater than 2147483647 – the maximum value for INT – hence the error. MySQL integer types and their ranges are listed here.

Also note that the (10) in INT(10) does not define the "size" of an integer. It specifies the display width of the column. This information is advisory only.

To fix the error, change your datatype to VARCHAR. Phone and Fax numbers should be stored as strings. See this discussion.

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

you can do noise reduction and then apply thresholding, but that you can you can play around with the configuration of the OCR by changing the --psm and --oem values

try: --psm 5 --oem 2

you can also look at the following link for further details here

You did not provide your validate.php code so I'm confused. You have to pass the data in JSON Format when when mail is success. You can use json_encode(); PHP function for that.

Add json_encdoe in validate.php in last

mail($to, $subject, $message, $headers); 
echo json_encode(array('success'=>'true'));

JS Code

success: function(data){ 
     if(data.success == true){ 
       alert('success'); 
    } 

Hope it works

They serve the actual image inside CSS so there will be less HTTP requests per page.

It is terrible, but you can try to use

select
SUBSTRING(Table1.Col1,0,PATINDEX('%|%=',Table1.Col1)) as myString
from
Table1

This code is probably not 100% right though. need to be adjusted

Add XAttribute in the constructor of the XElement, like

new XElement("Conn", new XAttribute("Server", comboBox1.Text));

You can also add multiple attributes or elements via the constructor

new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));

or you can use the Add-Method of the XElement to add attributes

XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);

You can try creating DBMS_XMLPARSER.parser object from the CLOB XML and get a DBMS_XMLDOM.DOMDocument object from it. Then use DBMS_XMLDOM package methods to get the value of any node.

   xml_            CLOB := 'X';
   p               DBMS_XMLPARSER.parser;
   doc_            DBMS_XMLDOM.DOMDocument;

      -- Convert the CLOB into a XML-document
      P := DBMS_XMLPARSER.newparser();
      -- Parse the clob and get the XML-document
      DBMS_XMLPARSER.parseclob(p, xml_);
      doc_ := DBMS_XMLPARSER.getDocument(p);

Then use the below methods to extract node value

DBMS_XMLDOM.getElementsByTagName(doc_, 'NodeName'); DBMS_XMLDOM.GetNodeValue(node_obj_);

Refer more about DBMS_XMLDOM methods here.

You can just use the pipe on its own:

"string1|string2"

for example:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|string2", "blah"));

Output:

blah, blah, string3

The main reason to use parentheses is to limit the scope of the alternatives:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(1|2)", "blah"));

has the same output. but if you just do this:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|2", "blah"));

you get:

blah, stringblah, string3

because you've said "string1" or "2".

If you don't want to capture that part of the expression use ?::

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(?:1|2)", "blah"));

The following code worked for me

//Parameter to be passed
var data = 'reportid=R3823&isSQL=1&filter=[]';
var xhr = new XMLHttpRequest();
xhr.open("POST", "Reporting.jsp"); //url.It can pdf file path
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.responseType = "blob";
xhr.onload = function () {
    if (this.status === 200) {
        var blob = new Blob([xhr.response]);
        const url = window.URL.createObjectURL(blob);
        var a = document.createElement('a');
        a.href = url;
        a.download = 'myFile.pdf';
        a.click();
        setTimeout(function () {
            // For Firefox it is necessary to delay revoking the ObjectURL
            window.URL.revokeObjectURL(data)
                , 100
        })
    }
};
xhr.send(data);

The simple way would be to disable the foreign key check; make the changes then re-enable foreign key check.

SET FOREIGN_KEY_CHECKS=0; -- to disable them
SET FOREIGN_KEY_CHECKS=1; -- to re-enable them

Addition with @cletus answer, You have to fetch all model fields(upper hierarchy) and set field.setAccessible(true) to access private members. Here is the full snippet:

@Override
public String toString() {
    StringBuilder result = new StringBuilder();
    String newLine = System.getProperty("line.separator");

    result.append(getClass().getSimpleName());
    result.append( " {" );
    result.append(newLine);

    List<Field> fields = getAllModelFields(getClass());

    for (Field field : fields) {
        result.append("  ");
        try {
            result.append(field.getName());
            result.append(": ");
            field.setAccessible(true);
            result.append(field.get(this));

        } catch ( IllegalAccessException ex ) {
//                System.err.println(ex);
        }
        result.append(newLine);
    }
    result.append("}");
    result.append(newLine);

    return result.toString();
}

private List<Field> getAllModelFields(Class aClass) {
    List<Field> fields = new ArrayList<>();
    do {
        Collections.addAll(fields, aClass.getDeclaredFields());
        aClass = aClass.getSuperclass();
    } while (aClass != null);
    return fields;
}

Use FirstOrDefault insted of SingleOrDefault..

SingleOrDefault returns a SINGLE element or null if no element is found. If 2 elements are found in your Enumerable then it throws the exception you are seeing

FirstOrDefault returns the FIRST element it finds or null if no element is found. so if there are 2 elements that match your predicate the second one is ignored

   public int GetPackage(int id,int emp)
           {
             int getpackages=Convert.ToInt32(EmployerSubscriptionPackage.GetAllData().Where(x
   => x.SubscriptionPackageID ==`enter code here` id && x.EmployerID==emp ).FirstOrDefault().ID);
               return getpackages;
           }

 1. var EmployerId = Convert.ToInt32(Session["EmployerId"]);
               var getpackage = GetPackage(employerSubscription.ID, EmployerId);

I disagree with the recommendation to create separate CSS files for non-editorial images.

Assuming the images are for UI purposes, it's presentation layer styling, and as mentioned above, if you're doing mobile UI's its definitely a good idea to keep all styling in a single file so it can be cached once.

As for "phone numbers" you should really consider the difference between a "subscriber number" and a "dialling number" and the possible formatting options of them.

A subscriber number is generally defined in the national numbering plans. The question itself shows a relation to a national view by mentioning "area code" which a lot of nations don't have. ITU has assembled an overview of the world's numbering plans publishing recommendation E.164 where the national number was found to have a maximum of 12 digits. With international direct distance calling (DDD) defined by a country code of 1 to 3 digits they added that up to 15 digits ... without formatting.

The dialling number is a different thing as there are network elements that can interpret exta values in a phone number. You may think of an answering machine and a number code that sets the call diversion parameters. As it may contain another subscriber number it must be obviously longer than its base value. RFC 4715 has set aside 20 bcd-encoded bytes for "subaddressing".

If you turn to the technical limitation then it gets even more as the subscriber number has a technical limit in the 10 bcd-encoded bytes in the 3GPP standards (like GSM) and ISDN standards (like DSS1). They have a seperate TON/NPI byte for the prefix (type of number / number plan indicator) which E.164 recommends to be written with a "+" but many number plans define it with up to 4 numbers to be dialled.

So if you want to be future proof (and many software systems run unexpectingly for a few decades) you would need to consider 24 digits for a subscriber number and 64 digits for a dialling number as the limit ... without formatting. Adding formatting may add roughly an extra character for every digit. So as a final thought it may not be a good idea to limit the phone number in the database in any way and leave shorter limits to the UX designers.

So I have been lurking on stack for so many years. This is actually my first time posting on here.

Anyhow, this might seem insane but I came across this post while struggling with the same issue and came up with a dirty solution. I know there are more elegant ways to perhaps set this as a property value but:

if you look at lines 12880-12883 in tcpdf.php :

$fx = ((($w - $this->getAbsFontMeasure($tmpfont['cw'][`110`])) / 2) * $this->k);
$fy = (($w - ((($tmpfont['desc']['Ascent'] - $tmpfont['desc']['Descent']) * $this->FontSizePt / 1000) / $this->k)) * $this->k);
$popt['ap']['n'][$onvalue] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`110`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
$popt['ap']['n']['Off'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`111`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);

and lines 13135-13138 :

$fx = ((($w - $this->getAbsFontMeasure($tmpfont['cw'][`108`])) / 2) * $this->k);
$fy = (($w - ((($tmpfont['desc']['Ascent'] - $tmpfont['desc']['Descent']) * $this->FontSizePt / 1000) / $this->k)) * $this->k);
$popt['ap']['n']['Yes'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`108`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);
$popt['ap']['n']['Off'] = sprintf('q %s BT /F%d %F Tf %F %F Td ('.chr(`109`).') Tj ET Q', $this->TextColor, $tmpfont['i'], $this->FontSizePt, $fx, $fy);

Those widgets are rendered from the zapfdingbats font set... just swap the character codes and voila... checks are radios and/or vice versa. This also opens up ideas to make a custom font set to use here and add some nice styling to your form elements.

Anyhow, just figured I would offer my two cents ... it worked awesome for me.

enable PAE/NX in virtualbox network config

Obvious caveats aside, if your array was actually like the one above, you could do

if [[ ${arr[*]} =~ d ]]
then
  do your thing
else
  do something

Another option is to use the getBoundingClientRect function. Please note that getBoundingClientRect will return an empty rect if the element's display is 'none'.

Example:

var elem = document.getElementById("myDiv");
if(elem) {
  var rect = elem.getBoundingClientRect();
  console.log("height: " + rect.height);  
}

UPDATE: Here is the same code written in 2020:

const elem = document.querySelector("#myDiv");
if(elem) {
  const rect = elem.getBoundingClientRect();
  console.log(`height: ${rect.height}`);
}

Check out the FileUtils class in Apache Commons - specifically iterateFiles:

Allows iteration over the files in given directory (and optionally its subdirectories).

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

Like mentioned by antonversal, reading the colors and using the colors option when creating the chart object works.

var chart3 = new Highcharts.Chart({colors: ['#458006', '#B0D18C']});

It's easy. Here is the full code.

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("Your URL")
driver.set_window_size(480, 320)

Make sure chrome driver is in your system path.

If the goal is to delete the objects a and b themselves (which appears to be the case), forming the list [a, b] is not helpful. Instead, one should keep a list of strings used as the names of those objects. These allow one to delete the objects in a loop, by accessing the globals() dictionary.

c = ['a', 'b']
# create and work with a and b    
for i in c:
    del globals()[i]

They work at different levels.

The simplest way to view the difference, from a beginner perspective is that jQuery is essentially an abstract of JavaScript, so the way we design a page for JavaScript is pretty much how we will do it for jQuery. Start with the DOM then build a behavior layer on top of that. Not so with Angular.Js. The process really begins from the ground up, so the end result is the desired view.

With jQuery you do dom-manipulations, with Angular.Js you create whole web-applications.

jQuery was built to abstract away the various browser idiosyncracies, and work with the DOM without having to add IE6 checks and so on. Over time, it developed a nice, robust API which allowed us to do a lot of things, but at its core, it is meant for dealing with the DOM, finding elements, changing UI, and so on. Think of it as working directly with nuts and bolts.

Angular.Js was built as a layer on top of jQuery, to add MVC concepts to front end engineering. Instead of giving you APIs to work with DOM, Angular.Js gives you data-binding, templating, custom components (similar to jQuery UI, but declarative instead of triggering through JS) and a whole lot more. Think of it as working at a higher level, with components that you can hook together, instead of directly at the nuts and bolts level.

Additionally, Angular.Js gives you structures and concepts that apply to various projects, like Controllers, Services, and Directives. jQuery itself can be used in multiple (gazillion) ways to do the same thing. Thankfully, that is way less with Angular.Js, which makes it easier to get into and out of projects. It offers a sane way for multiple people to contribute to the same project, without having to relearn a system from scratch.

A short comparison can be this-

jQuery

• Can be easily used by those who have proper knowledge on CSS selectors
• It is a library used for DOM Manipulations
• Has nothing to do with models
• Easily manipulate the contents of a webpage
• Apply styles to make UI more attractive
• Easy DOM traversal
• Effects and animation
• Simple to make AJAX calls and
• Utilities usability
• don't have a two-way binding feature
• becomes complex and difficult to maintain when the size of a project increases
• Sometimes you have to write more code to achieve the same functionality as in Angular.Js

Angular.Js

• It is an MVVM Framework
• Used for creating SPA (Single Page Applications)
• It has key features like routing, directives, two-way data binding, models, dependency injection, unit tests etc
• is modular
• Maintainable, when project size increases
• is Fast
• Two-Way data binding REST friendly MVC-based Pattern
• Deep Linking
• Templating
• Build-in form Validation
• Dependency Injection
• Localization
• Full Testing Environment
• Server Communication

And much more

You can use mb_strlen() to get the byte length using a encoding that only have byte-characters, without worring about multibyte or singlebyte strings. For example, as drake127 saids in a comment of mb_strlen, you can use '8bit' encoding:

<?php
    $string = 'Cién cañones por banda';
    echo mb_strlen($string, '8bit');
?>

You can have problems using strlen function since php have an option to overload strlen to actually call mb_strlen. See more info about it in http://php.net/manual/en/mbstring.overload.php

For trim the string by byte length without split in middle of a multibyte character you can use:

mb_strcut(string $str, int $start [, int $length [, string $encoding ]] )

And answering this seven years after the question was asked, it is possible to do this comparison using built-in methods:

Month.toInt("January") > Month.toInt("May")

becomes

Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
                 t => t.Equals("January", StringComparison.CurrentCultureIgnoreCase)) >
Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
                 t => t.Equals("May", StringComparison.CurrentCultureIgnoreCase))

Which can be refactored into an extension method for simplicity. The following is a LINQPad example (hence the Dump() method calls):

void Main()
{
    ("January".GetMonthIndex() > "May".GetMonthIndex()).Dump();
    ("January".GetMonthIndex() == "january".GetMonthIndex()).Dump();
    ("January".GetMonthIndex() < "May".GetMonthIndex()).Dump();
}

public static class Extension {
    public static int GetMonthIndex(this string month) {
        return Array.FindIndex( CultureInfo.CurrentCulture.DateTimeFormat.MonthNames,
                         t => t.Equals(month, StringComparison.CurrentCultureIgnoreCase));
    }
}

With output:

False
True
True

Second Thomas David Kehoe, with the following caveat --

If you are using node version manager (nvm), your global node modules will be stored under whatever version of node you are using at the time you saved the module.

So ~/.nvm/versions/node/{version}/lib/node_modules/.

Outlook adds the signature to the new unmodified messages (you should not modify the body prior to that) when you call MailItem.Display (which causes the message to be displayed on the screen) or when you access the MailItem.GetInspector property - you do not have to do anything with the returned Inspector object, but Outlook will populate the message body with the signature.

Once the signature is added, read the HTMLBody property and merge it with the HTML string that you are trying to set. Note that you cannot simply concatenate 2 HTML strings - the strings need to be merged. E.g. if you want to insert your string at the top of the HTML body, look for the "<body" substring, then find the next occurrence of ">" (this takes care of the <body> element with attributes), then insert your HTML string after that ">".

Outlook Object Model does not expose signatures at all.

On a general note, the name of the signature is stored in the account profile data accessible through the IOlkAccountManager Extended MAPI interface. Since that interface is Extended MAPI, it can only be accessed using C++ or Delphi. You can see the interface and its data in OutlookSpy if you click the IOlkAccountManager button.
Once you have the signature name, you can read the HTML file from the file system (keep in mind that the folder name (Signatures in English) is localized.
Also keep in mind that if the signature contains images, they must also be added to the message as attachments and the <img> tags in the signature/message body adjusted to point the src attribute to the attachments rather than a subfolder of the Signatures folder where the images are stored.
It will also be your responsibility to merge the HTML styles from the signature HTML file with the styles of the message itself.

If using Redemption is an option, you can use its RDOAccount object (accessible in any language, including VBA). New message signature name is stored in the 0x0016001F property, reply signature is in 0x0017001F. You can also use the RDOAccount.ReplySignature and NewSignature properties.
Redemption also exposes RDOSignature.ApplyTo method that takes a pointer to the RDOMail object and inserts the signature at the specified location correctly merging the images and the styles:

set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
set Drafts = Session.GetDefaultFolder(olFolderDrafts)
set   Msg = Drafts.Items.Add
Msg.To =   "[email protected]"
Msg.Subject  = "testing signatures"
Msg.HTMLBody = "<html><body>some <b>bold</b> message text</body></html>"
set Account = Session.Accounts.GetOrder(2).Item(1)   'first mail account
if  Not (Account  Is  Nothing)  Then
     set Signature = Account.NewMessageSignature
     if  Not (Signature  Is  Nothing)  Then
       Signature.ApplyTo Msg,  false   'apply at the bottom
     End If
End If
Msg.Send

EDIT: as of July 2017, MailItem.GetInspector in Outlook 2016 no longer inserts the signature. Only MailItem.Display does.

Major Difference between Object and MAP with Example :

it's Order of iteration in loop, In Map it follows the order as it was set while creation whereas in OBJECT does not.

SEE: OBJECT

const obj = {};
obj.prop1 = "Foo";
obj.prop2 = "Bar";
obj['1'] = "day";
console.log(obj)

**OUTPUT: {1: "day", prop1: "Foo", prop2: "Bar"}**

MAP

    const myMap = new Map()
    // setting the values
    myMap.set("foo", "value associated with 'a string'")
    myMap.set("Bar", 'value associated with keyObj')
    myMap.set("1", 'value associated with keyFunc')

OUTPUT:
**1.    ?0: Array[2]
1.   0: "foo"
2.   1: "value associated with 'a string'"
2.  ?1: Array[2]
1.   0: "Bar"
2.   1: "value associated with keyObj"
3.  ?2: Array[2]
1.   0: "1"
2.   1: "value associated with keyFunc"**

As I know, there is no direct support, but you can use plain-ol' javascript for that:

// Cookies
function createCookie(name, value, days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        var expires = "; expires=" + date.toGMTString();
    }
    else var expires = "";               

    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1, c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name, "", -1);
}

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

As apparantly no one mentioned it: you can also use the Numpy Docstring Standard. It is widely used in the scientific community.

• The specification of the format from numpy together with an example
• You have a sphinx extension to render it: numpydoc
• And an example of how beautiful a rendered docstring can look like: http://docs.scipy.org/doc/numpy/reference/generated/numpy.mean.html

The Napolean sphinx extension to parse Google-style docstrings (recommended in the answer of @Nathan) also supports Numpy-style docstring, and makes a short comparison of both.

And last a basic example to give an idea how it looks like:

def func(arg1, arg2):
    """Summary line.

    Extended description of function.

    Parameters
    ----------
    arg1 : int
        Description of arg1
    arg2 : str
        Description of arg2

    Returns
    -------
    bool
        Description of return value

    See Also
    --------
    otherfunc : some related other function

    Examples
    --------
    These are written in doctest format, and should illustrate how to
    use the function.

    >>> a=[1,2,3]
    >>> print [x + 3 for x in a]
    [4, 5, 6]
    """
    return True

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

NOTE - it looks like the question has changed some. The answer to the question of how you call an instance method from a static method is that you can't without passing an instance in as an argument or instantiating that instance inside the static method.

What follows is mostly to answer "how do you call a static method from another static method":

Bear in mind that there is a difference between static methods and class methods in Python. A static method takes no implicit first argument, while a class method takes the class as the implicit first argument (usually cls by convention). With that in mind, here's how you would do that:

If it's a static method:

test.dosomethingelse()

If it's a class method:

cls.dosomethingelse()

Surprise surprise, rebooting solved the issue (I thought I had already tried that).

The solution Robert Crovella mentioned in the comments may also be useful to someone else, since it's pretty similar to what I did to solve the issue the first time I had it.

File.OpenText() always uses an UTF-8 StreamReader implicitly. Create your own StreamReader instance instead and specify the desired encoding. like

using (StreamReader reader =  new StreamReader(@"C:\test.txt", Encoding.Default)
 {
 // ...
 }

This function creates an array of (length) elements where each element equals (value) as long as (value) is an integer or string of an integer. Any decimal numbers will be truncated. If you do want decimal numbers, replace "parseInt(" with "parseFloat("

function fillArray(length, intValue) {
     var vals = (new Array(length + 1)).join(intValue + '|').split('|').slice(0,length);
     for(var i = 0; i < length; i += 1) {
         vals[i] = parseInt(vals[i]);
     }
     return vals;
}

Examples:

fillArray(5, 7) // returns [7,7,7,7,7]
fillArray(5, 7.5) // returns [7,7,7,7,7]
fillArray(5, 200) // returns [200,200,200,200,200]

We had the same issue, using Plesk Onyx 17. Instead of messing up with rights etc., solution was to add nginx user into psacln group, in which all the other domain owners (users) were:

usermod -aG psacln nginx

Now nginx has rights to access .htaccess or any other file necessary to properly show the content.

On the other hand, also make sure that Apache is in psaserv group, to serve static content:

usermod -aG psaserv apache

And don't forget to restart both Apache and Nginx in Plesk after! (and reload pages with Ctrl-F5)

You can use GCD. It is a little more verbose than @synchronized, but works as a replacement:

let serialQueue = DispatchQueue(label: "com.test.mySerialQueue")
serialQueue.sync {
    // code
}

You can use setScale() to reduce the number of fractional digits to zero. Assuming value holds the value to be rounded:

BigDecimal scaled = value.setScale(0, RoundingMode.HALF_UP);
System.out.println(value + " -> " + scaled);

Using round() is a bit more involved as it requires you to specify the number of digits to be retained. In your examples this would be 3, but this is not valid for all values:

BigDecimal rounded = value.round(new MathContext(3, RoundingMode.HALF_UP));
System.out.println(value + " -> " + rounded);

(Note that BigDecimal objects are immutable; both setScale and round will return a new object.)

Create an empty folder and move the .mdb file to that folder. And try opening it from there. I tried it this way and it worked for me.

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

Even though the above solutions do work,This answer is for you in case you want to reverse the clock instead of undoing a git pull.I mean if you want to get your exact repo the way it was X Mins back then run the command

git reset --hard branchName@{"X Minutes ago"}

Note: before you actually go ahead and run this command please only try this command if you are sure about the time you want to go back to and heres about my situation.

I was currently on a branch develop, I was supposed to checkout to a new branch and pull in another branch lets say Branch A but I accidentally ran git pull origin B before checking out.

so to undo this change I tried this command

git reset --hard develop@{"10 Minutes ago"}

if you are on windows cmd and get error: unknown switch `e

try adding quotes like this

git reset --hard 'develop@{"10 Minutes ago"}'

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

For simple commands you can use:

ssh <ssh_args> command1 '&&' command2

or

ssh <ssh_args> command1 \&\& command2

To add an element to an array you need to use the format:

array[index] = element;

Where array is the array you declared, index is the position where the element will be stored, and element is the item you want to store in the array.

In your code, you'd want to do something like this:

int[] num = new int[args.length];
for (int i = 0; i < args.length; i++) {
    int neki = Integer.parseInt(args[i]);
    num[i] = neki;
}

The add() method is available for Collections like List and Set. You could use it if you were using an ArrayList (see the documentation), for example:

List<Integer> num = new ArrayList<>();
for (String s : args) {
    int neki = Integer.parseInt(s);
    num.add(neki);
}

COMMAND: python --version && python3 --version

OUTPUT:

Python 2.7.10
Python 3.7.1

ALIAS COMMAND: pyver

OUTPUT:

You can make an alias like "pyver" in your .bashrc file or else using a text accelerator like AText maybe.

My MAC OS Crashed recently. I reinstalled macOS 10.7.4 and Xcode 4.5. But all provisioning profiles were showing the following message in organizer.

Valid Signing identity not found

I struggled to find help for a couple of days. Later I realized that if you have migrated from one system to another(or formatted your system), you need to export your private key from your keychain from your old system to the new system (or new OS installed).

One can also export your developer profile/team developer profile in organizer.

Organizer > Teams > Developer Profile > Export

Hope it helps.

In Python, you can't just embed arbitrary Python expressions into literal strings and have it substitute the value of the string. You need to either:

sys.stderr.write("Usage: " + sys.argv[0])

or

sys.stderr.write("Usage: %s" % sys.argv[0])

Also, you may want to consider using the following syntax of print (for Python earlier than 3.x):

print >>sys.stderr, "Usage:", sys.argv[0]

Using print arguably makes the code easier to read. Python automatically adds a space between arguments to the print statement, so there will be one space after the colon in the above example.

In Python 3.x, you would use the print function:

print("Usage:", sys.argv[0], file=sys.stderr)

Finally, in Python 2.6 and later you can use .format:

print >>sys.stderr, "Usage: {0}".format(sys.argv[0])

This animation option works for 2.1.3 on a bar chart.

Slightly modified @Ross answer

animation: {
duration: 0,
onComplete: function () {
    // render the value of the chart above the bar
    var ctx = this.chart.ctx;
    ctx.font = Chart.helpers.fontString(Chart.defaults.global.defaultFontSize, 'normal', Chart.defaults.global.defaultFontFamily);
    ctx.fillStyle = this.chart.config.options.defaultFontColor;
    ctx.textAlign = 'center';
    ctx.textBaseline = 'bottom';
    this.data.datasets.forEach(function (dataset) {
        for (var i = 0; i < dataset.data.length; i++) {
            var model = dataset._meta[Object.keys(dataset._meta)[0]].data[i]._model;
            ctx.fillText(dataset.data[i], model.x, model.y - 5);
        }
    });
}}

On Windows platform, it is also possible to capture localhost traffic using Wireshark. What you need to do is to install the Microsoft loopback adapter, and then sniff on it.

('.cat').hover(
  function () {
    $(this).show();
  }, 
  function () {
    $(this).hide();
  }
);

It's the same for the others.

For the smooth fade in you can use fadeIn and fadeOut

A simple, newbie friendly way for looking into a file: git gui browser <branch> which lets you explore the contents of any file.

It's also there in the File menu of git gui. Most other -more advanced- GUI wrappers (Qgit, Egit, etc..) offer browsing/opening files as well.

FILE *f = fopen("file.txt", "w");
if (f == NULL)
{
    printf("Error opening file!\n");
    exit(1);
}

/* print some text */
const char *text = "Write this to the file";
fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

fclose(f);

in your baseadapter class constructor try to initialize LayoutInflater, normally i preferred this way,

public ClassBaseAdapter(Context context,ArrayList<Integer> listLoanAmount) {
    this.context = context;
    this.listLoanAmount = listLoanAmount;
    this.layoutInflater = LayoutInflater.from(context);
}

at the top of the class create LayoutInflater variable, hope this will help you

I don't think it's the right way to use angular. If a framework method doesnt exist, don't create it! This means the framework (here angular) doesnt work this way.

With angular you should not manipulate DOM like this (the jquery way), but use angular helper such as

<div ng-show="isLoading" class="loader"></div>

Or create your own directive (your own DOM component) in order to have full control on it.

BTW, you can see here http://caniuse.com/#search=queryselector querySelector is well supported and so can be use safely.

Do a describe on dba_arguments, dba_errors, dba_procedures, dba_objects, dba_source, dba_object_size. Each of these has part of the pictures for looking at the procedures and functions.

Also the object_type in dba_objects for packages is 'PACKAGE' for the definition and 'PACKAGE BODY" for the body.

If you are comparing schemas on the same database then try:

select * from dba_objects 
   where schema_name = 'ASCHEMA' 
     and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )
minus
select * from dba_objects 
where schema_name = 'BSCHEMA' 
  and object_type in ( 'PROCEDURE', 'PACKAGE', 'FUNCTION', 'PACKAGE BODY' )

and switch around the orders of ASCHEMA and BSCHEMA.

If you also need to look at triggers and comparing other stuff between the schemas you should take a look at the Article on Ask Tom about comparing schemas

send an output parameter like

@newId int output

at the end use

    select @newId = Scope_Identity() 

     return @newId 

For normal MySQL, just connect as the 'root' administrative super user, and issue the command:

FLUSH HOSTS

Even in the case of too many connections, MySQL should be keeping a connection in reserve so that a super user can connect.

The mysqladmin client generally connects as root anyway and issues the above SQL.

You can do that with list comprehension too:

A=[[x*100, x][x % 2 != 0] for x in range(1,11)]
print A

java.util.UUID.randomUUID();

I came across the same error after updating to the latest version of JQuery. Therefore I updated the jquery file I was working on, as stated in a previous answer, so it said .on("load") instead of .load().

This fix isn't very stable and sometimes it didn't work for me. Therefore to fix this issue you should update your code from:

    .load();

to

    .trigger("load");

I got this fix from the following source: https://github.com/stevenwanderski/bxslider-4/pull/1024

an abstract method must be call override in derived class other wise it will give compile-time error and in virtual you may or may not override it's depend if it's good enough use it

Example:

abstract class twodshape
{
    public abstract void area(); // no body in base class
}

class twodshape2 : twodshape
{
    public virtual double area()
    {
        Console.WriteLine("AREA() may be or may not be override");
    }
}

public class Demo {
    private static int i;
    private static Integer j;
    private static int k = -1;

    public static void main(String[] args) {
        System.out.println(i+" "+j+" "+k);
    }
}

OutPut: 0 null -1

to list only commits details for specific file changes,

git log --follow file_1.rb

to list difference among various commits for same file,

git log -p file_1.rb

to list only commit and its message,

git log --follow --oneline file_1.rb

In cross-platform, lowest-common-denominator sh you use:

#!/bin/sh
value=`cat config.txt`
echo "$value"

In bash or zsh, to read a whole file into a variable without invoking cat:

#!/bin/bash
value=$(<config.txt)
echo "$value"

Invoking cat in bash or zsh to slurp a file would be considered a Useless Use of Cat.

Note that it is not necessary to quote the command substitution to preserve newlines.

See: Bash Hacker's Wiki - Command substitution - Specialities.

Do not mix 12 and 15, use this

If you don't want to use the standard dictionary method (looping through the list incrementing the proper dict. key), you can try this:

>>> from itertools import groupby
>>> myList = words.split() # ['apple', 'banana', 'apple', 'strawberry', 'banana', 'lemon']
>>> [(k, len(list(g))) for k, g in groupby(sorted(myList))]
[('apple', 2), ('banana', 2), ('lemon', 1), ('strawberry', 1)]

It runs in O(n log n) time.

Can add disable like below and can get data on submit. something like this .. DEMO

Html

<input type="hidden" name="email" value="email" />
<input type="text" id="dis" class="disable" value="email"   name="email" >

JS

 $("#dis").attr('disabled','disabled');

CSS

    .disable { opacity : .35; background-color:lightgray; border:1px solid gray;}

2 great ways to ADD:

But the first way is more cleaner, since for the second you have to add a space at the beginning. This is to avoid the class name from joining with the previous class.

element.classList.add("d-flex", "align-items-center");
element.className += " d-flex align-items-center";

Then to REMOVE use the cleaner way, by use of classList

element.classList.remove("d-grid", "bg-danger");

Since the methods used in other answers seems quite complicated for such easy task, here is a new answer:

Instead of a ListedColormap, which produces a discrete colormap, you may use a LinearSegmentedColormap. This can easily be created from a list using the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

norm=plt.Normalize(-2,2)
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", ["red","violet","blue"])

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

More generally, if you have a list of values (e.g. [-2., -1, 2]) and corresponding colors, (e.g. ["red","violet","blue"]), such that the nth value should correspond to the nth color, you can normalize the values and supply them as tuples to the from_list method.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors

x,y,c = zip(*np.random.rand(30,3)*4-2)

cvals  = [-2., -1, 2]
colors = ["red","violet","blue"]

norm=plt.Normalize(min(cvals),max(cvals))
tuples = list(zip(map(norm,cvals), colors))
cmap = matplotlib.colors.LinearSegmentedColormap.from_list("", tuples)

plt.scatter(x,y,c=c, cmap=cmap, norm=norm)
plt.colorbar()
plt.show()

The javadoc says this:

"Returns an immutable list containing only the specified object. The returned list is serializable."

You ask:

Why would I want to have a separate method to do that?

Primarily as a convenience ... to save you having to write a sequence of statements to:

• create an empty list object
• add an element to it, and
• wrap it with an immutable wrapper.

It may also be a bit faster and/or save a bit of memory, but it is unlikely that these small savings will be significant. (An application that creates vast numbers of singleton lists is unusual to say the least.)

How does immutability play a role here?

It is part of the specification of the method; see above.

Are there any special useful use-cases for this method, rather than just being a convenience method?

Clearly, there are use-cases where it is convenient to use the singletonList method. But I don't know how you would (objectively) distinguish between an ordinary use-case and a "specially useful" one ...

Easiest way

The most trivial way to upload a file to an FTP server using .NET framework is using WebClient.UploadFile method:

WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.UploadFile("ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");

Advanced options

If you need a greater control, that WebClient does not offer (like TLS/SSL encryption, ascii/text transfer mode, active mode, transfer resuming, progress monitoring, etc), use FtpWebRequest. Easy way is to just copy a FileStream to an FTP stream using Stream.CopyTo:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;  

using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
using (Stream ftpStream = request.GetRequestStream())
{
    fileStream.CopyTo(ftpStream);
}

Progress monitoring

If you need to monitor an upload progress, you have to copy the contents by chunks yourself:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;  

using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
using (Stream ftpStream = request.GetRequestStream())
{
    byte[] buffer = new byte[10240];
    int read;
    while ((read = fileStream.Read(buffer, 0, buffer.Length)) > 0)
    {
        ftpStream.Write(buffer, 0, read);
        Console.WriteLine("Uploaded {0} bytes", fileStream.Position);
    } 
}

For GUI progress (WinForms ProgressBar), see C# example at:
How can we show progress bar for upload with FtpWebRequest

Uploading folder

If you want to upload all files from a folder, see
Upload directory of files to FTP server using WebClient.

For a recursive upload, see
Recursive upload to FTP server in C#

One issue I noticed that could cause errors is that in rrichter's answer, the code below:

<img src="b.jpg" style="position: absolute; top: 30; left: 70;"/>

should include the px units within the style eg.

<img src="b.jpg" style="position: absolute; top: 30px; left: 70px;"/>

Other than that, the answer worked fine. Thanks.

The issue here is that you just Added the reference to System.IO.Compression it is missing the reference to System.IO.Compression.Filesystem.dll

And you need to do it on .net 4.5 or later (because it doesn't exist on older versions).

I just posted a script on TechNet Maybe somebody would find it useful it requires .net 4.5 or 4.7

It is possible to create instances of Void if you change the security manager, so something like this:

static Void getVoid() throws SecurityException, InstantiationException,
        IllegalAccessException, InvocationTargetException {
    class BadSecurityManager extends SecurityManager {
    
        @Override
        public void checkPermission(Permission perm) { }
    
        @Override
        public void checkPackageAccess(String pkg) { }

    }
    System.setSecurityManager(badManager = new BadSecurityManager());
    Constructor<?> constructor = Void.class.getDeclaredConstructors()[0];
    if(!constructor.isAccessible()) {
        constructor.setAccessible(true);
    }
    return (Void) constructor.newInstance();
}

Obviously this is not all that practical or safe; however, it will return an instance of Void if you are able to change the security manager.

I've never seen this definition given elsewhere, but I think this sums up the differences given here fairly well:

Functional programming focuses on expressions

Procedural programming focuses on statements

Expressions have values. A functional program is an expression who's value is a sequence of instructions for the computer to carry out.

Statements don't have values and instead modify the state of some conceptual machine.

In a purely functional language there would be no statements, in the sense that there's no way to manipulate state (they might still have a syntactic construct named "statement", but unless it manipulates state I wouldn't call it a statement in this sense). In a purely procedural language there would be no expressions, everything would be an instruction which manipulates the state of the machine.

Haskell would be an example of a purely functional language because there is no way to manipulate state. Machine code would be an example of a purely procedural language because everything in a program is a statement which manipulates the state of the registers and memory of the machine.

The confusing part is that the vast majority of programming languages contain both expressions and statements, allowing you to mix paradigms. Languages can be classified as more functional or more procedural based on how much they encourage the use of statements vs expressions.

For example, C would be more functional than COBOL because a function call is an expression, whereas calling a sub program in COBOL is a statement (that manipulates the state of shared variables and doesn't return a value). Python would be more functional than C because it allows you to express conditional logic as an expression using short circuit evaluation (test && path1 || path2 as opposed to if statements). Scheme would be more functional than Python because everything in scheme is an expression.

You can still write in a functional style in a language which encourages the procedural paradigm and vice versa. It's just harder and/or more awkward to write in a paradigm which isn't encouraged by the language.

I'm still experiencing this behavior with jQuery 1.7.2. A simple workaround is to defer the execution of the click handler with setTimeout and let the browser do its magic in the meantime:

$("#myCheckbox").click( function() {
    var that = this;
    setTimeout(function(){
        alert($(that).is(":checked"));
    });
});

Try to reinstall it with the following code:

That is interesting subject. You can play around with two lifecycle hooks to figure out how it works: ngOnChanges and ngOnInit.

Basically when you set default value to Input that's mean it will be used only in case there will be no value coming on that component. And the interesting part it will be changed before component will be initialized.

Let's say we have such components with two lifecycle hooks and one property coming from input.

@Component({
  selector: 'cmp',
})
export class Login implements OnChanges, OnInit {
  @Input() property: string = 'default';

  ngOnChanges(changes) {
    console.log('Changed', changes.property.currentValue, changes.property.previousValue);
  }

  ngOnInit() {
    console.log('Init', this.property);
  }

}

Situation 1

Component included in html without defined property value

As result we will see in console: Init default

That's mean onChange was not triggered. Init was triggered and property value is default as expected.

Situation 2

Component included in html with setted property <cmp [property]="'new value'"></cmp>

As result we will see in console:

Changed new value Object {}

Init new value

And this one is interesting. Firstly was triggered onChange hook, which setted property to new value, and previous value was empty object! And only after that onInit hook was triggered with new value of property.

This code try to resolve this type of comparison versions.

Most of the version specifiers, like >= 1.0, are self-explanatory. The specifier ~> has a special meaning, best shown by example. ~> 2.0.3 is identical to >= 2.0.3 and < 2.1. ~> 2.1 is identical to >= 2.1 and < 3.0.

Expounding on what Ryan said, TypeScript embraces the JavaScript idioms in general.

var n = +"1"; // the unary + converts to number
var b = !!"2"; // the !! converts truthy to true, and falsy to false
var s = ""+3; // the ""+ converts to string via toString()

The easier way to do it is just:

ul li:after {
    content: url('../images/small_triangle.png');
}

pseudo-code:

minutes = floor(326.4/60)
seconds = round(326.4 - minutes * 60)

create php-file with:

<?php
    print shell_exec( 'whoami' );
?>

or

<?php echo exec('whoami'); ?>

try the output in your web-browser. if the output is not your user example: www-data then proceed to next step

open as root:

/etc/apache2/envvars

look for these lines:

export APACHE_RUN_USER=user-name

export APACHE_RUN_GROUP=group-name

example:

export APACHE_RUN_USER=www-data

export APACHE_RUN_GROUP=www-data

where:

username = your username that has access to the folder you are using group = group you've given read+write+execute access

change it to:

export APACHE_RUN_USER="username"

export APACHE_RUN_GROUP="group"

if your user have no access yet:

sudo chmod 775 -R "directory of folder you want to give r/w/x access"

@FXML

Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS instead of LOGON_TYPE_NETWORK or LOGON_TYPE_INTERACTIVE. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it. The last code snippet in this post suggests that impersonating across a forest does work, but it doesn't specifically say anything about trust being set up. So this may be worth trying:

const int LOGON_TYPE_NEW_CREDENTIALS = 9;
const int LOGON32_PROVIDER_WINNT50 = 3;
bool returnValue = LogonUser(user, domain, password,
            LOGON_TYPE_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50,
            ref tokenHandle);

MSDN says that LOGON_TYPE_NEW_CREDENTIALS only works when using LOGON32_PROVIDER_WINNT50.

Python 3.x version of Etaoin's answer for completeness:

from tkinter.filedialog import askopenfilename
filename = askopenfilename()

The solutions provided here can only be applied if the user defined types are used in table definitions only, and if the UDT columns are not indexed.

Some developers also have SP's and functions using UDT parameters, which is not covered either. (see comments on Robin's link and in the Connect entry)

The Connect entry from 2007 has finally been closed after 3 years:

Thank you for submitting this suggestion, but given its priority relative to the many other items in our queue, it is unlikely that we will actually complete it. As such, we are closing this suggestion as “won’t fix”.

I tried to solve a similiar problem ALTERing XML SCHEMA COLLECTIONS, and the steps seem to mostly apply to ALTER TYPE, too:

To drop a UDT, the following steps are necessary:

• If a table column references the UDT, it has to be converted to the underlying type
• If the table column has a default constraint, drop the default constraint
• If a procedure or function has UDT parameters, the procedure or function has to be dropped
• If there is an index on a UDT column, the index has to be dropped
• If the index is a primary key, all foreign keys have to be dropped
• If there are computed columns based on a UDT column, the computed columns have to be dropped
• If there are indexes on these computed columns, the indexes have to be dropped
• If there are schema-bound views, functions, or procedures based on tables containing UDT columns, these objects have to be dropped

If your GridView is databond, make an index column in the resultset you retrive like this:

select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]

In the command control you want to use make the value of CommandArgument property equal to the row index of the DataSet table RowIndex like this:

<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />

Use the OnRowCommand event to fire on clicking the link button like this:

<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">

Finally the code behind you can then do whatever you like when the event is triggered like this:

protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
    if(pnlMsgBody.Visible == false)
    {
        pnlMsgBody.Visible = true;
    }
    else
    {
        pnlMsgBody.Visible = false;
    }
}

A simple approach is to make use of ;

For example:

ENV=prod; ansible-playbook -i inventories/$ENV --extra-vars "env=$ENV"  deauthorize_users.yml --check

Another solution: use flexjson.jar: http://mvnrepository.com/artifact/net.sf.flexjson/flexjson/3.2

List<yourEntity> yourEntityList = deserializer.deserialize(new InputStreamReader(input));

Replace your draw line with

g.drawOval(X - r, Y - r, r, r)

This should make the top-left of your circle the right place to make the center be (X,Y), at least as long as the point (X - r,Y - r) has both components in range.

You have the join statement backwards try:

print ', '.join(set_3)

You need to create an user "ODBC" for MySql with no password. Do that in PHPMyAdmin. That will solve your problem.

But remember, if it's only your local development environment, no problem. It'll create a serious security hole in your production environment.

hi here i posted one video ,and it explains how to generate unique random number

  public List<int> random_generator(){

  Random random = new Random();

   List<int> random_container = new List<int>;

     do{

       int random_number = random.next(10);

      if(!random_container.contains(random_number){

       random_container.add(random_number)
  }
}
   while(random_container.count!=10);


     return random_container; 
  }

here ,,, in random container you will get non repeated 10 numbers starts from 0 to 9(10 numbers) as random.. thank you........

You need to create a git repo locally, add your project files to that repo, commit them to the local repo, and then sync that repo to your repo on github. You can find good instructions on how to do the latter bit on github, and the former should be easy to do with the software you've downloaded.

You could try DELETE FROM <your table >;.

The server will show you the name of the restriction and the table, and deleting that table you can delete what you need.

Use a+ to open a file for reading, writing as well as create it if it doesn't exist.

a+ Opens a file for both appending and reading. The file pointer is at the end of the file if the file exists. The file opens in the append mode. If the file does not exist, it creates a new file for reading and writing. -Python file modes

with open('"File.txt', 'a+') as file:
    print(file.readlines())
    file.write("test")

Note: opening file in a with block makes sure that the file is properly closed at the block's end, even if an exception is raised on the way. It's equivalent to try-finally, but much shorter.

if needed programmatic from a PDE or JDT code:

public static void setWorkspaceAutoBuild(boolean flag) throws CoreException 
{
IWorkspace workspace = ResourcesPlugin.getWorkspace();
final IWorkspaceDescription description = workspace.getDescription();
description.setAutoBuilding(flag);
workspace.setDescription(description);
}

The parameter to the COUNT function is an expression that is to be evaluated for each row. The COUNT function returns the number of rows for which the expression evaluates to a non-null value. ( * is a special expression that is not evaluated, it simply returns the number of rows.)

There are two additional modifiers for the expression: ALL and DISTINCT. These determine whether duplicates are discarded. Since ALL is the default, your example is the same as count(ALL 1), which means that duplicates are retained.

Since the expression "1" evaluates to non-null for every row, and since you are not removing duplicates, COUNT(1) should always return the same number as COUNT(*).

No one touched on it yet but it is something that every PHP developer should be able to speak at length about: Why is register_globals bad?

answer shouldn't be a pointer, the intent is obviously to hold a character. scanf takes the address of this character, so it should be called as

char answer;
scanf(" %c", &answer);

Next, your "or" statement is formed incorrectly.

if (answer == 'Y' || answer == 'y')

What you wrote originally asks to compare answer with the result of 'Y' || 'y', which I'm guessing isn't quite what you wanted to do.

In this case no conditionals are needed to set the variable.

This one-liner XPath expression:

boolean(joined-subclass)

is true() only when the child of the current node, named joined-subclass exists and it is false() otherwise.

The complete stylesheet is:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

 <xsl:template match="class">
   <xsl:variable name="subexists"
        select="boolean(joined-subclass)"
   />

   subexists:  <xsl:text/>
   <xsl:value-of select="$subexists" />
 </xsl:template>
</xsl:stylesheet>

Do note, that the use of the XPath function boolean() in this expression is to convert a node (or its absense) to one of the boolean values true() or false().

You may define your enum like so and use cast where needed

public enum MyEnum
{
    VariablePeriods = 1,
    FixedPeriods = 2
}

Usage

public class Entity
{
    public MyEnum Property { get; set; }
}

var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;

THIS DOES NOT FORCE APPLICATION TO WORK AS ADMINISTRATOR.
This is a simplified version of the this answer, above by @NG

public bool IsUserAdministrator()
{
    try
    {
        WindowsIdentity user = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(user);
        return principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch
    {
        return false;
    }
}

private List<String[]> addresses = new ArrayList<String[]>();

this will work defenitely...

You can use

go build *.go 
go run *.go

both will work also you may use

go build .
go run .

The answer is:

<a href="page.html" onclick="return false">page link</a>

A basic but simple to understand answer:

    Program logic...
    ActiveSheet.Protect
End Sub

Maybe this can help

string input = "hello123world";
bool isDigitPresent = input.Any(c => char.IsDigit(c));

answer from msdn.

If you are talking about the length of the string, you can use len():

>>> s = 'please answer my question'
>>> len(s)  # number of characters in s
25

If you need the size of the string in bytes, you need sys.getsizeof():

>>> import sys
>>> sys.getsizeof(s)
58

Also, don't call your string variable str. It shadows the built-in str() function.

I needed to see localhost on my android device as well (Samsung S3) as I was developing a Java Web-application.
By far the fastest and easiest way is to go to this link and follow instructions: https://developer.chrome.com/devtools/docs/remote-debugging

* Note: You have to use Google Chrome.*
My summary of the above link:

• Connect PC with Phone over USB.
• Turn on Phone's "Developer options" from Settings
• Go to about:inspect URL in PC's browser
• Check "Discover USB Devices" (forward Ports if you are using them in your web-application)
• Copy/paste localhost required link to text field in browser and click Open.
  
  

Piece of cake

Solved my own problem. This line:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

needs to be:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

or since Java 7:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

$("input[type=checkbox]").on("change", function() { 

    if (this.checked) {

      //do your stuff

     }
});

NW.js

(Previously known as node-webkit)

I would suggest NW.js if you are familiar with Node or experienced with JavaScript.

NW.js is an app runtime based on Chromium and node.js.

Features

• Apps written in modern HTML5, CSS3, JS and WebGL
• Complete support for Node.js APIs and all its third party modules.
• Good performance: Node and WebKit run in the same thread: Function calls are made straightforward; objects are in the same heap and can just reference each other
• Easy to package and distribute apps
• Available on Linux, Mac OS X and Windows

You can find the NW.js repo here, and a good introduction to NW.js here. If you fancy learning Node.js I would recommend this SO post with a lot of good links.

Started having this problem after "downgrading" from VS 2019 Enterprise to VS 2019 Professional. Although the error was showing in the Error window, I could build the project without problems. Tried many solutions from this thread and others like equalizing target frameworks, delete and make the reference again, deleting .suo file, etc. What worked for me was simply deleting the project in my local repository and cloning it again from the remote repository.

Many times when crawling we run into problems where content that is rendered on the page is generated with Javascript and therefore scrapy is unable to crawl for it (eg. ajax requests, jQuery craziness).

However, if you use Scrapy along with the web testing framework Selenium then we are able to crawl anything displayed in a normal web browser.

Some things to note:

• You must have the Python version of Selenium RC installed for this to work, and you must have set up Selenium properly. Also this is just a template crawler. You could get much crazier and more advanced with things but I just wanted to show the basic idea. As the code stands now you will be doing two requests for any given url. One request is made by Scrapy and the other is made by Selenium. I am sure there are ways around this so that you could possibly just make Selenium do the one and only request but I did not bother to implement that and by doing two requests you get to crawl the page with Scrapy too.

• This is quite powerful because now you have the entire rendered DOM available for you to crawl and you can still use all the nice crawling features in Scrapy. This will make for slower crawling of course but depending on how much you need the rendered DOM it might be worth the wait.

Reference: http://snipplr.com/view/66998/

See the MSDN reference table for maximum numbers/sizes.

Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1

There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)

You can use regular expressions like this:

SELECT * FROM pet WHERE name REGEXP 'Bob|Smith'; 

In java 8 , It's really easy to get timestamp in UTC by using java 8 java.time.Instant library :

Instant.now();

That few word of code will return the UTC Timestamp.

1- first downlaod it(graphviz 2.38).

2- install org.graphviz.Graphviz-2.38-graphviz-2.38.

3- now add "C:\Program Files (x86)\Graphviz2.38\bin" and "C:\Program Files (x86)\Graphviz2.38\bin\dot.exe" to path like this video
note:in windows 8 you must use ; for path example: C:\Program Files;D:\Users;E:\file\

This is a common problem . when we start the ftp connection only the external ip opens the port for pasv connection. but the ip behind the NAT doesn't open the connection so passive connection fails with PASV command

we need to specify that while opening the connection so open connection with

ftp -p {host}

So what's the problem,

It's a ’ (RIGHT SINGLE QUOTATION MARK - U+2019) character which is being decoded as CP-1252 instead of UTF-8. If you check the encodings table, then you see that this character is in UTF-8 composed of bytes 0xE2, 0x80 and 0x99. If you check the CP-1252 code page layout, then you'll see that each of those bytes stand for the individual characters â, € and ™.

and how can I fix it?

Use UTF-8 instead of CP-1252 to read, write, store, and display the characters.

I have the Content-Type set to UTF-8 in both my <head> tag and my HTTP headers:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

This only instructs the client which encoding to use to interpret and display the characters. This doesn't instruct your own program which encoding to use to read, write, store, and display the characters in. The exact answer depends on the server side platform / database / programming language used. Do note that the one set in HTTP response header has precedence over the HTML meta tag. The HTML meta tag would only be used when the page is opened from local disk file system instead of from HTTP.

In addition, my browser is set to Unicode (UTF-8):

This only forces the client which encoding to use to interpret and display the characters. But the actual problem is that you're already sending ’ (encoded in UTF-8) to the client instead of ’. The client is correctly displaying ’ using the UTF-8 encoding. If the client was misinstructed to use, for example ISO-8859-1, you would likely have seen ââ¬â¢ instead.

I am using ASP.NET 2.0 with a database.

This is most likely where your problem lies. You need to verify with an independent database tool what the data looks like.

If the ’ character is there, then you aren't connecting to the database correctly. You need to tell the database connector to use UTF-8.

If your database contains ’, then it's your database that's messed up. Most probably the tables aren't configured to use UTF-8. Instead, they use the database's default encoding, which varies depending on the configuration. If this is your issue, then usually just altering the table to use UTF-8 is sufficient. If your database doesn't support that, you'll need to recreate the tables. It is good practice to set the encoding of the table when you create it.

You're most likely using SQL Server, but here is some MySQL code (copied from this article):

CREATE DATABASE db_name CHARACTER SET utf8;
CREATE TABLE tbl_name (...) CHARACTER SET utf8;

If your table is however already UTF-8, then you need to take a step back. Who or what put the data there. That's where the problem is. One example would be HTML form submitted values which are incorrectly encoded/decoded.

Here are some more links to learn more about the problem:

You might try searching the internet for ".htaccess Options not allowed here".

A suggestion I found (using google) is:

Check to make sure that your httpd.conf file has AllowOverride All.

A .htaccess file that works for me on Mint Linux (placed in the Laravel /public folder):

# Apache configuration file
# http://httpd.apache.org/docs/2.2/mod/quickreference.html

# Turning on the rewrite engine is necessary for the following rules and
# features. "+FollowSymLinks" must be enabled for this to work symbolically.

<IfModule mod_rewrite.c>
    Options +FollowSymLinks
    RewriteEngine On
</IfModule>

# For all files not found in the file system, reroute the request to the
# "index.php" front controller, keeping the query string intact

<IfModule mod_rewrite.c>
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

Hope this helps you. Otherwise you could ask a question on the Laravel forum (http://forums.laravel.com/), there are some really helpful people hanging around there.

Here you've got a very detailed explanation of their differences

http://kyleschaeffer.com/development/css-font-size-em-vs-px-vs-pt-vs/

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

Yes. It is done with a filter on the appender.

You can always format a date by extracting the parts and combine them using string functions:

var date = new Date();_x000D_
var dateStr =_x000D_
  ("00" + (date.getMonth() + 1)).slice(-2) + "/" +_x000D_
  ("00" + date.getDate()).slice(-2) + "/" +_x000D_
  date.getFullYear() + " " +_x000D_
  ("00" + date.getHours()).slice(-2) + ":" +_x000D_
  ("00" + date.getMinutes()).slice(-2) + ":" +_x000D_
  ("00" + date.getSeconds()).slice(-2);_x000D_
console.log(dateStr);

Follow the steps carefully to get the image first=>

    $img = DB::table('students')->where('id',$id)->first();
    $image_path = $img->photo;
    
    unlink($image_path);
    DB::table('students')->where('id',$id)->delete();

If you are newbie, welcome to Symfony2, an open-source project so if you want to learn a lot, you can open the source !

From "Form.php" :

getData() getNormData() getViewData()

You can find more details in this file.

Use callbacks. Something like this should work based on your sample code.

function someFunc() {

callAjaxfunc(function() {
    console.log('Pass2');
});

}

function callAjaxfunc(callback) {
    //All ajax calls called here
    onAjaxSuccess: function() {
        callback();
    };
    console.log('Pass1');    
}

This will print Pass1 immediately (assuming ajax request takes atleast a few microseconds), then print Pass2 when the onAjaxSuccess is executed.

The existing answers show a possible solution for single files or file types. However, you can define the charset standard in VS Code by following this path:

File > Preferences > Settings > Encoding > Choose your option

This will define a character set as default. Besides that, you can always change the encoding in the lower right corner of the editor (blue symbol line) for the current project.

using gawk exhibits the problem:

 gawk '{ print $NF-1, $NF}' filename
1 2
2 3
-1 one
-1 three
# cat filename
1 2
2 3
one
one two three

I just put gawk on Solaris 10 M4000: So, gawk is the cuplrit on the $NF-1 vs. $(NF-1) issue. Next question what does POSIX say? per:

http://www.opengroup.org/onlinepubs/009695399/utilities/awk.html

There is no direction one way or the other. Not good. gawk implies subtraction, other awks imply field number or subtraction. hmm.

I ran into the exact same problem on Ubuntu 12.04, because I installed matplotlib (within a virtualenv) using

pip install matplotlib

To make long story short, my advice is: don't try to install matplotlib using pip or by hand; let a real package manager (e.g. apt-get / synaptic) install it and all its dependencies for you.

Unfortunately, matplotlib's backends (alternative methods for actually rendering your plots) have all sorts of dependencies that pip will not deal with. Even worse, it fails silently; that is, pip install matplotlib appears to install matplotlib successfully. But when you try to use it (e.g. pyplot.show()), no plot window will appear. I tried all the different backends that people on the web suggest (Qt4Agg, GTK, etc.), and they all failed (i.e. when I tried to import matplotlib.pyplot, I get ImportError because it's trying to import some dependency that's missing). I then researched how to install those dependencies, but it just made me want to give up using pip (within virtualenv) as a viable installation solution for any package that has non-Python package dependencies.

The whole experience sent me crawling back to apt-get / synaptic (i.e. the Ubuntu package manager) to install software like matplotlib. That worked perfectly. Of course, that means you can only install into your system directories, no virtualenv goodness, and you are stuck with the versions that Ubuntu distributes, which may be way behind the current version...

Try

ALLOWED_HOSTS = ['*']

Less secure if you're not firewalled off or on a public LAN, but it's what I use and it works.

EDIT: Interestingly enough I've been needing to add this to a few of my 1.8 projects even when DEBUG = True. Very unsure why.

EDIT: This is due to a Django security update as mentioned in my comment.

this may help for auto adjusting the image height having image 100% width

image: { width: "100%", resizeMode: "center" "contain", height: undefined, aspectRatio: 1, }

If you are fortunate enough to be running Python 3.4+, you can use pathlib:

>>> from pathlib import Path
>>> dirname = '/home/reports'
>>> filename = 'daily'
>>> suffix = '.pdf'
>>> Path(dirname, filename).with_suffix(suffix)
PosixPath('/home/reports/daily.pdf')

The only way to remove the dotted line (to my knowledge) is with css hacking using plugin.

• Install the User CSS (or User JS & CSS) plugin, which allows adding CSS rules per site.

• Once on Google Docs, click the plugins icon, toggle the OFF to ON button, and add the following css code:

.

.kix-page-compact::before{
    border-top: none;
}

Should work like a charm.

For compatibility with all browsers stick with .ico.

.png is getting more and more support though as it is easier to create using multiple programs.

for .ico

<link rel="shortcut icon" href="http://example.com/myicon.ico" />

for .png, you need to specify the type

<link rel="icon" type="image/png" href="http://example.com/image.png" />

Try this,

def get_dic_from_two_lists(keys, values):
    return { keys[i] : values[i] for i in range(len(keys)) }

Assume we have two lists country and capital

country = ['India', 'Pakistan', 'China']
capital = ['New Delhi', 'Islamabad', 'Beijing']

Then create dictionary from the two lists:

print get_dic_from_two_lists(country, capital)

The output is like this,

{'Pakistan': 'Islamabad', 'China': 'Beijing', 'India': 'New Delhi'}

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

Service vs Factory

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

Factory Provider

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

• Singleton and will only be created once

• Reusable components

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

• Can use other dependencies

• Usually used when the service instance requires complex creation logic

• Cannot be injected in .config() function.

• Used for non configurable services

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

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

Service Provider

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

• Singleton and will only be created once

• Reusable components

• Services are used for communication between controllers to share data

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

• Dependencies are injected as constructor arguments

• Used for simple creation logic

• Cannot be injected in .config() function.

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

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

Sample Demo

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

AngularJS .service

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

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

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

AngularJS .factory

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

    var factory = {}; 

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

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

    return factory;
});

1) Add the following line to /etc/security/limits.conf

webuser hard nofile 64000

then login as webuser

su - webuser

2) Edit following two files for webuser

append .bashrc and .bash_profile file by running

echo "ulimit -n 64000" >> .bashrc ; echo "ulimit -n 64000" >> .bash_profile

3) Log out, then log back in and verify that the changes have been made correctly:

$ ulimit -a | grep open
open files                      (-n) 64000

Thats it and them boom, boom boom.

if you just want to see the folder size and not the sub-folders, you can use:

du -hs /path/to/directory

Update:

You should know that du shows the used disk space; and not the file size.

You can use --apparent-size if u want to see sum of actual file sizes.

--apparent-size
      print  apparent  sizes,  rather  than  disk  usage; although the apparent size is usually smaller, it may be larger due to holes in ('sparse')
      files, internal fragmentation, indirect blocks, and the like

And of course theres no need for -h (Human readable) option inside a script.

Instead You can use -b for easier comparison inside script.

But You should Note that -b applies --apparent-size by itself. And it might not be what you need.

-b, --bytes
      equivalent to '--apparent-size --block-size=1'

so I think, you should use --block-size or -B

#!/bin/bash
SIZE=$(du -B 1 /path/to/directory | cut -f 1 -d "   ")    
# 2GB = 2147483648 bytes
# 10GB = 10737418240 bytes
if [[ $SIZE -gt 2147483648 && $SIZE -lt 10737418240 ]]; then
    echo 'Condition returned True'
fi

try this line of code.

textview.setTypeface(textview.getTypeface(), Typeface.DEFAULT_BOLD);

here , it will get current Typeface from this textview and replace it using new Typeface. New typeface here is DEFAULT_BOLD but you can apply many more.

Since its a question of the past but the problem of present. Would suggest one more solution: Just pass the key and values to the function and you will get a map object.

var map = {};
function addValueToMap(key, value) {
map[key] = map[key] || [];
map[key].push(value);
}

At the moment of writing, JavaScript is receiving a new data type: BigInt. It is a TC39 proposal at stage 4 to be included in EcmaScript 2020. BigInt is available in Chrome 67+, FireFox 68+, Opera 54 and Node 10.4.0. It is underway in Safari, et al... It introduces numerical literals having an "n" suffix and allows for arbitrary precision:

var a = 123456789012345678901012345678901n;

Precision will still be lost, of course, when such a number is (maybe unintentionally) coerced to a number data type.

And, obviously, there will always be precision limitations due to finite memory, and a cost in terms of time in order to allocate the necessary memory and to perform arithmetic on such large numbers.

For instance, the generation of a number with a hundred thousand decimal digits, will take a noticeable delay before completion:

console.log(BigInt("1".padEnd(100000,"0")) + 1n)

...but it works.

I think button onclick="history.back();" is one way to solve the problem. But it might not work in the following cases.

1. If the page gets refreshed or reloaded.

2. If the user opens the link in a new page.

To overcome these, the following code could be used if you know which page you have to return to. E.g. If you have a no of links on one page and the back button is to be used to return to that page.

<input type="button" onclick="document.location.href='filename';" value="Back" name="button" class="btn">

You don't escape quotes in regular expressions

this.Vals.replace(/["']/g, "")

It would look like this:

public static final String WELCOME_MESSAGE = "Hello, welcome to the server";

If the constants are for use just in a single class, you'd want to make them private instead of public.

If you are eager to know how to use an OR condition in a Ruby switch case:

So, in a case statement, a , is the equivalent of || in an if statement.

case car
   when 'Maruti', 'Hyundai'
      # Code here
end

See "How A Ruby Case Statement Works And What You Can Do With It".

By default Jsonresult "Deny get"

Suppose if we have method like below

  [HttpPost]
 public JsonResult amc(){}

By default it "Deny Get".

In the below method

public JsonResult amc(){}

When you need to allowget or use get ,we have to use JsonRequestBehavior.AllowGet.

public JsonResult amc()
{
 return Json(new Modle.JsonResponseData { Status = flag, Message = msg, Html = html }, JsonRequestBehavior.AllowGet);
}

You can mark source directory as a source root like so:

• Right-click on source directory
• Mark Directory As --> Source Root
• File --> Invalidate Caches / Restart... -> Invalidate and Restart

lea is an abbreviation of "load effective address". It loads the address of the location reference by the source operand to the destination operand. For instance, you could use it to:

lea ebx, [ebx+eax*8]

to move ebx pointer eax items further (in a 64-bit/element array) with a single instruction. Basically, you benefit from complex addressing modes supported by x86 architecture to manipulate pointers efficiently.

If you use use the Jquery from Google CDN, seriously it will improve the performance by 5 to 10 times the one which you add into your page, which gets downloaded. And also, you will get the latest version of the Jquery files.

The difference between both files i.e. jquery.js and jquery.min.js is just the file size, due to this the files are getting downloaded faster. :)

 api.com/users?id=id1,id2,id3,id4,id5
 api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5

IMO, above calls does not looks RESTful, however these are quick and efficient workaround (y). But length of the URL is limited by webserver, eg tomcat.

RESTful attempt:

POST http://example.com/api/batchtask

   [
    {
      method : "GET",
      headers : [..],
      url : "/users/id1"
    },
    {
      method : "GET",
      headers : [..],
      url : "/users/id2"
    }
   ]

Server will reply URI of newly created batchtask resource.

201 Created
Location: "http://example.com/api/batchtask/1254"

Now client can fetch batch response or task progress by polling

GET http://example.com/api/batchtask/1254

Here's a function that doesn't require any packages to be installed. You give it a Date object (or a character that it can convert into a Date), and it adds n months to that date without changing the day of the month (unless the month you land on doesn't have enough days in it, in which case it defaults to the last day of the returned month). Just in case it doesn't make sense reading it, there are some examples below.

Function definition

addMonth <- function(date, n = 1){
  if (n == 0){return(date)}
  if (n %% 1 != 0){stop("Input Error: argument 'n' must be an integer.")}

  # Check to make sure we have a standard Date format
  if (class(date) == "character"){date = as.Date(date)}

  # Turn the year, month, and day into numbers so we can play with them
  y = as.numeric(substr(as.character(date),1,4))
  m = as.numeric(substr(as.character(date),6,7))
  d = as.numeric(substr(as.character(date),9,10))

  # Run through the computation
  i = 0
  # Adding months
  if (n > 0){
    while (i < n){
      m = m + 1
      if (m == 13){
        m = 1
        y = y + 1
      }
      i = i + 1
    }
  }
  # Subtracting months
  else if (n < 0){
    while (i > n){
      m = m - 1
      if (m == 0){
        m = 12
        y = y - 1
      }
      i = i - 1
    }
  }

  # If past 28th day in base month, make adjustments for February
  if (d > 28 & m == 2){
      # If it's a leap year, return the 29th day
      if ((y %% 4 == 0 & y %% 100 != 0) | y %% 400 == 0){d = 29}
      # Otherwise, return the 28th day
      else{d = 28}
    }
  # If 31st day in base month but only 30 days in end month, return 30th day
  else if (d == 31){if (m %in% c(1, 3, 5, 7, 8, 10, 12) == FALSE){d = 30}}

  # Turn year, month, and day into strings and put them together to make a Date
  y = as.character(y)

  # If month is single digit, add a leading 0, otherwise leave it alone
  if (m < 10){m = paste('0', as.character(m), sep = '')}
  else{m = as.character(m)}

  # If day is single digit, add a leading 0, otherwise leave it alone
  if (d < 10){d = paste('0', as.character(d), sep = '')}
  else{d = as.character(d)}

  # Put them together and convert return the result as a Date
  return(as.Date(paste(y,'-',m,'-',d, sep = '')))
}

Some examples

Adding months

> addMonth('2014-01-31', n = 1)
[1] "2014-02-28"  # February, non-leap year
> addMonth('2014-01-31', n = 5)
[1] "2014-06-30"  # June only has 30 days, so day of month dropped to 30
> addMonth('2014-01-31', n = 24)
[1] "2016-01-31"  # Increments years when n is a multiple of 12 
> addMonth('2014-01-31', n = 25)
[1] "2016-02-29"  # February, leap year

Subtracting months

> addMonth('2014-01-31', n = -1)
[1] "2013-12-31"
> addMonth('2014-01-31', n = -7)
[1] "2013-06-30"
> addMonth('2014-01-31', n = -12)
[1] "2013-01-31"
> addMonth('2014-01-31', n = -23)
[1] "2012-02-29"

In C++11 you have raw string literals. Sort of like here-text in shells and script languages like Python and Perl and Ruby.

const char * vogon_poem = R"V0G0N(
             O freddled gruntbuggly thy micturations are to me
                 As plured gabbleblochits on a lurgid bee.

                (by Prostetnic Vogon Jeltz; see p. 56/57)
)V0G0N";

All the spaces and indentation and the newlines in the string are preserved.

These can also be utf-8|16|32 or wchar_t (with the usual prefixes).

I should point out that the escape sequence, V0G0N, is not actually needed here. Its presence would allow putting )" inside the string. In other words, I could have put

                "(by Prostetnic Vogon Jeltz; see p. 56/57)"

(note extra quotes) and the string above would still be correct. Otherwise I could just as well have used

const char * vogon_poem = R"( ... )";

The parens just inside the quotes are still needed.

I agree with @Vishnu's answer. I would like to add that if you want to use the application user in your trigger you can use "context_info" to pass the info to the trigger.

I found following very helpful in doing that: http://jasondentler.com/blog/2010/01/exploiting-context_info-for-fun-and-audit

You need to escape your backslash by preceding it with, yes, another backslash:

print("\\")

And for versions prior to Python 3:

print "\\"

The \ character is called an escape character, which interprets the character following it differently. For example, n by itself is simply a letter, but when you precede it with a backslash, it becomes \n, which is the newline character.

As you can probably guess, \ also needs to be escaped so it doesn't function like an escape character. You have to... escape the escape, essentially.

See the Python 3 documentation for string literals.

As of python 2.7, optparse is deprecated, and will hopefully go away in the future.

argparse is better for all the reasons listed on its original page (https://code.google.com/archive/p/argparse/):

• handling positional arguments
• supporting sub-commands
• allowing alternative option prefixes like + and /
• handling zero-or-more and one-or-more style arguments
• producing more informative usage messages
• providing a much simpler interface for custom types and actions

More information is also in PEP 389, which is the vehicle by which argparse made it into the standard library.

interface MyProps {
  ...
}

interface MyState {
  value: string
}

class App extends React.Component<MyProps, MyState> {
  ...
}

// Or with hooks, something like

const App = ({}: MyProps) => {
  const [value, setValue] = useState<string>('');
  ...
};

type's are fine too like in @nitzan-tomer's answer, as long as you're consistent.

why don't you try this?

password="your password"
username="username"
Ip="<IP>"
sshpass -p "$password" scp /<PATH>/final.txt $username@$Ip:/root/<PATH>

Another way of doing this would be using Aggregation. You should be able to achieve a similar result using a single query. Such as this:

Item.objects.values("contest").annotate(Count("id"))

I did not test this specific query, but this should output a count of the items for each value in contests as a dictionary.

Im not sure if this is the "Professional" way to do it and i'm not entirely sure if it works for everything.

boolean gotError = false;

do {
    try {
        // Code You're Trying
    } catch ( FileNotFoundException ex ) {
        // Exception
        gotError = true;
    }
} while ( gotError = true );

You can use the & operator on the Method instance of your method to convert the method to a block.

Example:

def foo(arg)
  p arg
end

def bar(&block)
  p 'bar'
  block.call('foo')
end

bar(&method(:foo))

See std::clock() function.

const clock_t begin_time = clock();
// do something
std::cout << float( clock () - begin_time ) /  CLOCKS_PER_SEC;

If you want calculate execution time for self ( not for user ), it is better to do this in clock ticks ( not seconds ).

EDIT:
responsible header files - <ctime> or <time.h>

other way to compile using -Xlint:unchecked through command line

javac abc.java -Xlint:unchecked

it will show the unchecked and unsafe warnings.

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

To check where the core dumps are generated, run:

sysctl kernel.core_pattern

or:

cat /proc/sys/kernel/core_pattern

where %e is the process name and %t the system time. You can change it in /etc/sysctl.conf and reloading by sysctl -p.

If the core files are not generated (test it by: sleep 10 & and killall -SIGSEGV sleep), check the limits by: ulimit -a.

If your core file size is limited, run:

ulimit -c unlimited

to make it unlimited.

Then test again, if the core dumping is successful, you will see “(core dumped)” after the segmentation fault indication as below:

Segmentation fault: 11 (core dumped)

See also: core dumped - but core file is not in current directory?

Ubuntu

In Ubuntu the core dumps are handled by Apport and can be located in /var/crash/. However, it is disabled by default in stable releases.

For more details, please check: Where do I find the core dump in Ubuntu?.

macOS

For macOS, see: How to generate core dumps in Mac OS X?

I think what you want is a different content mode. Try using UIViewContentModeScaleToFill. This will scale the content to fit the size of ur UIImageView by changing the aspect ratio of the content if necessary.

Have a look to the content mode section on the official doc to get a better idea of the different content mode available (it is illustrated with images).

Select select = new Select(_element);
List<WebElement> selectedOptions = select.getAllSelectedOptions();

if(selectedOptions.size() > 0){
    return true;
}else{
    return false;
}

Rebooting my MacBook fixed this issue for me.

You don't need heredocs or eval, mongo itself can act as an interpreter.

#!/usr/bin/env mongo
var db = new Mongo().getDB("someDatabase");
db.dropDatabase();

Make the file executable and run it.

While the accepted answer is very true, just want to point out that AllowTransparency has some downfalls. It does not allow child window controls to show up, ie WebBrowser, and it usually forces software rendering which can have negative performance effects.

There is a better work around though.

When you want to create a window with no border that is resizeable and is able to host a WebBrowser control or a Frame control pointed to a URL you simply couldn't, the contents of said control would show empty.

I found a workaround though; in the Window, if you set the WindowStyle to None, ResizeMode to NoResize (bear with me, you will still be able to resize once done) then make sure you have UNCHECKED AllowsTransparency you will have a static sized window with no border and will show the browser control.

Now, you probably still want to be able to resize right? Well we can to that with a interop call:

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

    [DllImportAttribute("user32.dll")]
    public static extern bool ReleaseCapture();

    //Attach this to the MouseDown event of your drag control to move the window in place of the title bar
    private void WindowDrag(object sender, MouseButtonEventArgs e) // MouseDown
    {
        ReleaseCapture();
        SendMessage(new WindowInteropHelper(this).Handle,
            0xA1, (IntPtr)0x2, (IntPtr)0);
    }

    //Attach this to the PreviewMousLeftButtonDown event of the grip control in the lower right corner of the form to resize the window
    private void WindowResize(object sender, MouseButtonEventArgs e) //PreviewMousLeftButtonDown
    {
        HwndSource hwndSource = PresentationSource.FromVisual((Visual)sender) as HwndSource;
        SendMessage(hwndSource.Handle, 0x112, (IntPtr)61448, IntPtr.Zero);
    }

And voila, A WPF window with no border and still movable and resizable without losing compatibility with with controls like WebBrowser

Declare the array size will solve your problem

 String[] title = {
            "Abundance",
            "Anxiety",
            "Bruxism",
            "Discipline",
            "Drug Addiction"
        };
    String urlbase = "http://www.somewhere.com/data/";
    String imgSel = "/logo.png";
    String[] mStrings = new String[title.length];

    for(int i=0;i<title.length;i++) {
        mStrings[i] = urlbase + title[i].toLowerCase() + imgSel;

        System.out.println(mStrings[i]);
    }

This is really late to the party, but none of the solutions above worked for me. I didn't want the "Found total xxx records" so I added info:false to the config. When I removed that everything worked.

I should note that the first page loaded fine. When I hit next, the second page loaded, but immediately threw the above console error

According google docs ,we should not use fitsSystemWindows attribute in app theme, it is intended to use in layout files. Using in themes can causes problem in toast messages .

Check Issue here & example of problem caused here

<item name="android:fitsSystemWindows">true</item>

Example of using correct way and which works fine with windowTranslucentStatus as well.

You can use the application called Supervisor. In supervisor config you can define multiple services and ways to execute the same.

For Java and Spring boot applications the command would be java -jar springbootapp.jar.

Options can be provided to keep the application running always.So if the EC2 restart then Supervisor will restart you application

I found Supervisor easy to use compared to putting startup scripts in /etc/init.d/.The startup scripts would hang or go into waiting state in case of errors .

import/export is now doing the job with ES6. I still tend to prefix not exported functions with _ if most of my functions are exported.

If you export only a class (like in angular projects), it's not needed at all.

export class MyOpenClass{

    open(){
         doStuff()
         this._privateStuff()
         return close();
    }

    _privateStuff() { /* _ only as a convention */} 

}

function close(){ /*... this is really private... */ }

If you are presenting a ViewController modally, and want to go back to the root ViewController, take care to dismiss this modally presented ViewController before you go back to the root ViewController otherwise this ViewController will not be removed from Memory and cause Memory leaks.

If you have more than one view in the layout file android.R.layout.simple_list_item_1 then you'll have to pass the third argument android.R.id.text1 to specify the view that should be filled with the array elements (values). But if you have just one view in your layout file, there is no need to specify the third argument.

Just the same way as you would do in normal Java code.

for (Map.Entry<String, String> entry : countries.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    // ...
}

However, scriptlets (raw Java code in JSP files, those <% %> things) are considered a poor practice. I recommend to install JSTL (just drop the JAR file in /WEB-INF/lib and declare the needed taglibs in top of JSP). It has a <c:forEach> tag which can iterate over among others Maps. Every iteration will give you a Map.Entry back which in turn has getKey() and getValue() methods.

Here's a basic example:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach items="${map}" var="entry">
    Key = ${entry.key}, value = ${entry.value}<br>
</c:forEach>

Thus your particular issue can be solved as follows:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<select name="country">
    <c:forEach items="${countries}" var="country">
        <option value="${country.key}">${country.value}</option>
    </c:forEach>
</select>

You need a Servlet or a ServletContextListener to place the ${countries} in the desired scope. If this list is supposed to be request-based, then use the Servlet's doGet():

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    Map<String, String> countries = MainUtils.getCountries();
    request.setAttribute("countries", countries);
    request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);
}

Or if this list is supposed to be an application-wide constant, then use ServletContextListener's contextInitialized() so that it will be loaded only once and kept in memory:

public void contextInitialized(ServletContextEvent event) {
    Map<String, String> countries = MainUtils.getCountries();
    event.getServletContext().setAttribute("countries", countries);
}

In both cases the countries will be available in EL by ${countries}.

Hope this helps.

Try this CSS:

body {
  margin: 0;
  padding: 0;
}

.logo {
  float: left;
}
/* ~~ Top Navigation Bar ~~ */

#navigation-container {
  width: 1200px;
  margin: 0 auto;
  height: 70px;
}

.navigation-bar {
  background-color: #352d2f;
  height: 70px;
  width: 100%;
}

#navigation-container img {
  float: left;
}

#navigation-container ul {
  padding: 0px;
  margin: 0px;
  text-align: center;
  display:inline-block;
}

#navigation-container li {
  list-style-type: none;
  padding: 0px;
  height: 24px;
  margin-top: 4px;
  margin-bottom: 4px;
  display: inline;
}

#navigation-container li a {
  color: white;
  font-size: 16px;
  font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
  text-decoration: none;
  line-height: 70px;
  padding: 5px 15px;
  opacity: 0.7;
}

#menu {
  float: right;
}

You might want to have some of columns being normalized and the others be unchanged like some of regression tasks which data labels or categorical columns are unchanged So I suggest you this pythonic way (It's a combination of @shg and @Cina answers ):

features_to_normalize = ['A', 'B', 'C']
# could be ['A','B'] 

df[features_to_normalize] = df[features_to_normalize].apply(lambda x:(x-x.min()) / (x.max()-x.min()))

I typically return null. It provides a quick and easy mechanism to detect if something screwed up without throwing exceptions and using tons of try/catch all over the place.

Nested functions and closures are now supported by many languages, including MATLAB. JavaScript promotes closures as a first class design principle.

Sadly, Octave does not support closures (nested functions with lexical scoping).

According http://osdir.com/ml/octave-bug-tracker/2013-06/msg00210.html one might even get the impression that the developers do not want or are unable to get it right.

This will break a lot of code, both ways. No workaround.

In my case (python) it failed because I had these two lines of code in the file, inherited from an older code

http.client.HTTPConnection._http_vsn = 10 http.client.HTTPConnection._http_vsn_str = 'HTTP/1.0'

java.time

Using the java.time framework built into Java 8 and later.

import java.time.LocalDateTime;
import java.time.Instant;
import java.time.ZoneId;

long epoch = Long.parseLong("1081157732");
Instant instant = Instant.ofEpochSecond(epoch);
ZonedDateTime.ofInstant(instant, ZoneOffset.UTC); # ZonedDateTime = 2004-04-05T09:35:32Z[UTC]

In this case you should better use ZonedDateTime to mark it as date in UTC time zone because Epoch is defined in UTC in Unix time used by Java.

ZoneOffset contains a handy constant for the UTC time zone, as seen in last line above. Its superclass, ZoneId can be used to adjust into other time zones.

ZoneId zoneId = ZoneId.of( "America/Montreal" );

One more way:

j=i[0]
for k in range(1,len(i)):
    j = numpy.vstack([j,i[k]])

In this case j will be a numpy array

Rails 6.1 added a new 'syntax' for comparison operators in where conditions, for example:

Post.where('id >': 9)
Post.where('id >=': 9)
Post.where('id <': 3)
Post.where('id <=': 3)

So your query can be rewritten as follows:

Note
  .where(user_id: current_user.id, notetype: p[:note_type], 'date >', p[:date])
  .order(date: :asc, created_at: :asc)

Here is a link to PR where you can find more examples.

Looks like your IndexPartial action method has an argument which is a complex object. If you are passing a a lot of data (complex object), It might be a good idea to convert your action method to a HttpPost action method and use jQuery post to post data to that. GET has limitation on the query string value.

[HttpPost]
public PartialViewResult IndexPartial(DashboardViewModel m)
{
   //May be you want to pass the posted model to the parial view?
   return PartialView("_IndexPartial");
}

Your script should be

var url = "@Url.Action("IndexPartial","YourControllerName")";

var model = { Name :"Shyju", Location:"Detroit"};

$.post(url, model, function(res){
   //res contains the markup returned by the partial view
   //You probably want to set that to some Div.
   $("#SomeDivToShowTheResult").html(res);
});

Assuming Name and Location are properties of your DashboardViewModel class and SomeDivToShowTheResult is the id of a div in your page where you want to load the content coming from the partialview.

Sending complex objects?

You can build more complex object in js if you want. Model binding will work as long as your structure matches with the viewmodel class

var model = { Name :"Shyju", 
              Location:"Detroit", 
              Interests : ["Code","Coffee","Stackoverflow"]
            };

$.ajax({
    type: "POST",
    data: JSON.stringify(model),
    url: url,
    contentType: "application/json"
}).done(function (res) {
    $("#SomeDivToShowTheResult").html(res);
});

For the above js model to be transformed to your method parameter, Your View Model should be like this.

public class DashboardViewModel
{
  public string Name {set;get;}
  public string Location {set;get;}
  public List<string> Interests {set;get;}
}

And in your action method, specify [FromBody]

[HttpPost]
public PartialViewResult IndexPartial([FromBody] DashboardViewModel m)
{
    return PartialView("_IndexPartial",m);
}

I assume X and Y are arrays? If so, there's a very simple way to do this:

x = [1, 1, 2, 4]
y = [1, 2, 2, 2]

# intersection
x & y            # => [1, 2]

# union
x | y            # => [1, 2, 4]

# difference
x - y            # => [4]

If you want to convert an existing string to raw string, then we can reassign that like below

s1 = "welcome\tto\tPython"
raw_s1 = "%r"%s1
print(raw_s1)

Will print

welcome\tto\tPython

Stuarts' answer is correct, but if you are not sure if you are saving the titles in lowercase, you can also make a case insensitive search

There are a lot of answered questions in Stack Overflow with more data on this:

Example 1

Example 2

The training and validation sets are used during training.

for each epoch
    for each training data instance
        propagate error through the network
        adjust the weights
        calculate the accuracy over training data
    for each validation data instance
        calculate the accuracy over the validation data
    if the threshold validation accuracy is met
        exit training
    else
        continue training

Once you're finished training, then you run against your testing set and verify that the accuracy is sufficient.

Training Set: this data set is used to adjust the weights on the neural network.

Validation Set: this data set is used to minimize overfitting. You're not adjusting the weights of the network with this data set, you're just verifying that any increase in accuracy over the training data set actually yields an increase in accuracy over a data set that has not been shown to the network before, or at least the network hasn't trained on it (i.e. validation data set). If the accuracy over the training data set increases, but the accuracy over the validation data set stays the same or decreases, then you're overfitting your neural network and you should stop training.

Testing Set: this data set is used only for testing the final solution in order to confirm the actual predictive power of the network.

Write a small program that does the trick. Depending on the language you use it takes between 10 seconds to 1 min. Faster than installing any application for sure. In command line with proper setup PHP

php -q

<?php $t=file_get_contents("filename"); echo str_replace(array("\n", "\r"), array("\\n", "\\r"), $t); ?>

Update to Davids answer to even detect browsers that do not support pushstate:

  document.location.href = "/new-url";
}

User Defined Class Array List Example

import java.util.*;  

public class UserDefinedClassInArrayList {

    public static void main(String[] args) {

        //Creating user defined class objects  
        Student s1=new Student(1,"AAA",13);  
        Student s2=new Student(2,"BBB",14);  
        Student s3=new Student(3,"CCC",15); 

        ArrayList<Student> al=new ArrayList<Student>();
        al.add(s1);
        al.add(s2);  
        al.add(s3);  

        Iterator itr=al.iterator();  

        //traverse elements of ArrayList object  
        while(itr.hasNext()){  
            Student st=(Student)itr.next();  
            System.out.println(st.rollno+" "+st.name+" "+st.age);  
        }  
    }
}

class Student{  
    int rollno;  
    String name;  
    int age;  
    Student(int rollno,String name,int age){  
        this.rollno=rollno;  
        this.name=name;  
        this.age=age;  
    }  
} 

Program Output:

1 AAA 13

2 BBB 14

3 CCC 15

String str = "to";
str.replace("to", "xyz");

Just try it :)
