This solution is similar to the one given by Dominic Watson, which uses $validators and is the one I like best. The only changes are that you can watch an expression.

$validators A collection of validators that are applied whenever the model value changes. The key value within the object refers to the name of the validator while the function refers to the validation operation. The validation operation is provided with the model value as an argument and must return a true or false value depending on the response of that validation

from https://code.angularjs.org/1.3.15/docs/api/ng/type/ngModel.NgModelController

I'm using angular 1.3. My directive looks something like this

angular.module('app').directive("passwordConfirm", function() {
    "use strict";
    return {
        require : "ngModel",
        restrict : "A",
        scope : {
            //We will be checking that our input is equals to this expression
            passwordConfirm : '&'
        },
        link : function(scope, element, attrs, ctrl) {
            //The actual validation
            function passwordConfirmValidator(modelValue, viewValue) {
                return modelValue == scope.passwordConfirm();
            }
            //Register the validaton when this input changes
            ctrl.$validators.passwordConfirm = passwordConfirmValidator;
            //Also validate when the expression changes
            scope.$watch(scope.passwordConfirm, ctrl.$validate);
        }
    };
});

To use it

<input type="password" ng-model="user.password"/>
<input type="password" ng-model="user.confirmPassword" 
                password-confirm="user.password" />

This formula does not require a column letter reference ("A", "B", etc.). It returns the value of the cell one row above in the same column.

=INDIRECT(ADDRESS(ROW()-1,COLUMN()))

Write it like this:

String CmbTitle = (cmb.SelectedItem as ComboBoxItem).Content.ToString()

For a bordered and scrollable table, use this (replace variables, $ starting texts)

If you use thead, tfoot or th, just replace tr:first-child and tr-last-child and td with them.

#table-wrap {
  border: $border solid $color-border;
  border-radius: $border-radius;
}
table {
  border-collapse: collapse;
  border-spacing: 0;
}
table td { border: $border solid $color-border; }
table td:first-child { border-left: none; }
table td:last-child { border-right: none; }
table tr:first-child td { border-top: none; }
table tr:last-child td { border-bottom: none; }
table tr:first-child td:first-child { border-top-left-radius: $border-radius; }
table tr:first-child td:last-child { border-top-right-radius: $border-radius; }
table tr:last-child td:first-child { border-bottom-left-radius: $border-radius; }
table tr:last-child td:last-child { border-bottom-right-radius: $border-radius; }

HTML:

<div id=table-wrap>
  <table>
    <tr>
       <td>1</td>
       <td>2</td>
    </tr>
    <tr>
       <td>3</td>
       <td>4</td>
    </tr>
  </table>
</div>

If you drill down through the abstractions of the IdentityDbContext you'll find that it looks just like your derived DbContext. The easiest route is Olav's answer, but if you want more control over what's getting created and a little less dependency on the Identity packages have a look at my question and answer here. There's a code example if you follow the link, but in summary you just add the required DbSets to your own DbContext subclass.

Use Console.Write instead, so there's no newline written:

Console.Write("What is your name? ");
var name = Console.ReadLine();

Intelephense 1.3 added undefined type, function, constant, class constant, method, and property diagnostics, where previously in 1.2 there was only undefined variable diagnostics.

Some frameworks are written in a way that provide convenient shortcuts for the user but make it difficult for static analysis engines to discover symbols that are available at runtime.

Stub generators like https://github.com/barryvdh/laravel-ide-helper help fill the gap here and using this with Laravel will take care of many of the false diagnostics by providing concrete definitions of symbols that can be easily discovered.

Still, PHP is a very flexible language and there may be other instances of false undefined symbols depending on how code is written. For this reason, since 1.3.3, intelephense has config options to enable/disable each category of undefined symbol to suit the workspace and coding style.

These options are: intelephense.diagnostics.undefinedTypes intelephense.diagnostics.undefinedFunctions intelephense.diagnostics.undefinedConstants intelephense.diagnostics.undefinedClassConstants intelephense.diagnostics.undefinedMethods intelephense.diagnostics.undefinedProperties intelephense.diagnostics.undefinedVariables

Setting all of these to false except intelephense.diagnostics.undefinedVariables will give version 1.2 behaviour. See the VSCode settings UI and search for intelephense.

Adding on to the answer from @Ohmen, you could also add an external flag to create the data volume outside of docker compose. This way docker compose would not attempt to create it. Also you wouldn't have to worry about losing the data inside the data-volume in the event of $ docker-compose down -v. The below example is from the official page.

version: "3.8"

services:
  db:
    image: postgres
    volumes:
      - data:/var/lib/postgresql/data

volumes:
  data:
    external: true

Another possile solution providing the possibility of more complicated keys can be found here: http://insidecoffe.blogspot.de/2013/04/indexable-hashmap-implementation.html

I am unsure which of them is wrong because you did not provide your HTML, but one of these does not exist:

var str = document.getElementById("cal_preview").value;
var str1 = document.getElementById("year").value;
var str2 = document.getElementById("holiday").value;
var str3 = document.getElementById("cal_option").value;

There is either no element with the id cal_preview, year, holiday, cal_option, or some combination.

Therefore, JavaScript is unable to read the value of something that does not exist.

EDIT:

If you want to check that the element exists first, you could use an if statement for each:

var str,
element = document.getElementById('cal_preview');
if (element != null) {
    str = element.value;
}
else {
    str = null;
}

You could obviously change the else statement if you want or have no else statement at all, but that is all about preference.

A general answer

select * from [dbo].[SplitString]('1,2',',') -- Will work 

but

select [dbo].[SplitString]('1,2',',')  -- will not work and throws this error

<div>
    <h1> Ok </h1>
    <button type='button'>Button</button>
    <div style="clear:both;"></div>
</div>

css

div {
    background: purple;
}

div h1 {
    text-align: center;
}

div button {
    float: right;
    margin-right:10px;

}

if you need to increase reserved memory, there are VM parameters -Xms and -Xmx, usage e.g. -Xms512m -Xmx512m . There is also parameter -XX:MaxPermSize=256m which changes memory reserved for permanent generation

If your application runs as windows service, in Control panels -> Administration tools -> Services you can add some run parameters to your service

I use this expression. It takes into account a space after a comma, which I have come across.

(?:,"|^"|, ")(""|[\w\W]*?)(?=",|"$)|(?:,(?!")|^(?!"))([^,]*?)(?=$|,)|(\r\n|\n)

    public static void OpenDialog (Activity activity, DialogFragment fragment){

    final FragmentManager fm = ((FragmentActivity)activity).getSupportFragmentManager();

    fragment.show(fm, "tag");
}

Try Date.now().

The skipping is most likely due to garbage collection. Typically garbage collection can be avoided by reusing variables as much as possible, but I can't say specifically what methods you can use to reduce garbage collection pauses.

You can specify a Python version for pip to use:

pip3.4 install requests

Python 3.4 has pip support built-in, so you can also use:

python3.4 -m pip install

If you're running Ubuntu (or probably Debian as well), you'll need to install the system pip3 separately:

sudo apt-get install python3-pip

This will install the pip3 executable, so you can use it, as well as the earlier mentioned python3.4 -m pip:

pip3 install requests

Upgrade your mysql-connector" lib package with your mysql version like below i am using 8.0.13 version and in pom I changed the version:

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
    <version>8.0.13</version>
</dependency>

My problem has resolved after this.

check it out:

http://java.sun.com/docs/books/tutorial/uiswing/components/icon.html#getresource

I came here because I was sure none of the answers here were quite...poetic:

function checkextension() {_x000D_
  var file = document.querySelector("#fUpload");_x000D_
  if ( /\.(jpe?g|png|gif)$/i.test(file.files[0].name) === false ) { alert("not an image!"); }_x000D_
}

<input type="file" id="fUpload" onchange="checkextension()"/>

Change the type to submit and give it a name (and remove the useless onclick and flat out the 90's style uppercased tags/attributes).

<input type="submit" name="foo" value="A" />
<input type="submit" name="foo" value="B" />
...

The value will be available by $_POST['foo'] (if the parent <form> has a method="post").

If you have issues like the question ask above regarding the exception thrown when the solution is executed, the problem is permission, not properly granted to the users of that group to access the database/stored procedure. All you need do is to do something like what i have below, replacing mine with your database name, stored procedures (function)and the type of permission or role or who you are granting the access to.

USE [StableEmployee]
GO
GRANT EXEC ON dbo.GetAllEmployees TO PUBLIC

/****** Object: StoredProcedure [dbo].[GetAllEmployees] Script Date: 01/27/2016 16:27:27 ******/

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[GetAllEmployees]
as
Begin
Select EmployeeId, Name, Gender, City, DepartmentId
From tblEmployee

End

May be this will help, I'd prefer pure JS wherever possible, it improves the performance drastically as you won't have lots of JQuery function calls.

var obj = [];
var elems = $("input[class=email]");

for (i = 0; i < elems.length; i += 1) {
    var id = this.getAttribute('title');
    var email = this.value;
    tmp = {
        'title': id,
        'email': email
    };

    obj.push(tmp);
}

php artisan migrate --path=/database/migrations/fileName.php

You don't have to refresh for migration because refresh means Rollback all migrations and run them all again.

I think some cool expiriments in Python with NodeBox would be a cool start. It has functions to draw things from squares to complex paths. It can even take in images from the Mac iSight/ Webcam and manipulate it by scaling, rotating and applying filters.

Sadly, it's only for Mac OS X, so I don't think it would be of much use to teach it, but as an example (if you have a Mac yourself) for what's possible with a little bit of code, it would be pretty nifty.

There is now a HDF5 based clone of pickle called hickle!

https://github.com/telegraphic/hickle

import hickle as hkl 

data = { 'name' : 'test', 'data_arr' : [1, 2, 3, 4] }

# Dump data to file
hkl.dump( data, 'new_data_file.hkl' )

# Load data from file
data2 = hkl.load( 'new_data_file.hkl' )

print( data == data2 )

EDIT:

There also is the possibility to "pickle" directly into a compressed archive by doing:

import pickle, gzip, lzma, bz2

pickle.dump( data, gzip.open( 'data.pkl.gz',   'wb' ) )
pickle.dump( data, lzma.open( 'data.pkl.lzma', 'wb' ) )
pickle.dump( data,  bz2.open( 'data.pkl.bz2',  'wb' ) )

Write it like this:

string[] files = Directory.GetFiles(@".\Archive", "*.zip");

. is for relative to the folder where you started your exe, and @ to allow \ in the name.

When using filters, you pass it as a second parameter. You can also add a third parameter to specify if you want to search recursively for the pattern.

In order to get the folder where your .exe actually resides, use:

var executingPath = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);

I'm not sure how to achieve your desired effect through the selector itself -- after all, by definition, there is one selector for the whole list.

However, you can get control on selection changes and draw whatever you want. In this sample project, I make the selector transparent and draw a bar on the selected item.

SELECT *
FROM  yourtable
where DATE_FORMAT(date_created, '%Y-%m') = date_format(DATE_SUB(curdate(), INTERVAL 1 month),'%Y-%m')

This should return all the records from the previous calendar month, as opposed to the records for the last 30 or 31 days.

If portability is not a concern, and you just want to get the pid on Windows without a lot of hassle while using code that is tested and known to work on all modern versions of Windows, you can use kohsuke's winp library. It is also available on Maven Central for easy consumption.

Process process = //...;
WinProcess wp = new WinProcess(process);
int pid = wp.getPid();

If you're on a mac, by far the simplest way to install is to use easy_install

sudo easy_install boto3

Instead of using (getApplicationContext) use YourActivity.this

Just set parent div css property "text-align:center;"

 <div style="text-align:center; width:100%">
        <img src="img.png"> 
 </div>

Most of these solutions depend on there being an odd number of items so that you can take the middle item and center it. What if you have an even number of items that you still want to be evenly distributed? Here's a more general solution. This category will evenly distribute any number of items along either the vertical or horizontal axis.

Example usage to vertically distribute 4 labels within their superview:

[self.view addConstraints:
     [NSLayoutConstraint constraintsForEvenDistributionOfItems:@[label1, label2, label3, label4]
                                        relativeToCenterOfItem:self.view
                                                    vertically:YES]];

NSLayoutConstraint+EvenDistribution.h

@interface NSLayoutConstraint (EvenDistribution)

/**

 * or vertically relative to the center of another item. This is used to maintain an even
 * distribution of subviews even when the superview is resized.

I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

An alternative approach is resample, which can handle duplicate dates in addition to missing dates. For example:

df.resample('D').mean()

resample is a deferred operation like groupby so you need to follow it with another operation. In this case mean works well, but you can also use many other pandas methods like max, sum, etc.

Here is the original data, but with an extra entry for '2013-09-03':

             val
date           
2013-09-02     2
2013-09-03    10
2013-09-03    20    <- duplicate date added to OP's data
2013-09-06     5
2013-09-07     1

And here are the results:

             val
date            
2013-09-02   2.0
2013-09-03  15.0    <- mean of original values for 2013-09-03
2013-09-04   NaN    <- NaN b/c date not present in orig
2013-09-05   NaN    <- NaN b/c date not present in orig
2013-09-06   5.0
2013-09-07   1.0

I left the missing dates as NaNs to make it clear how this works, but you can add fillna(0) to replace NaNs with zeroes as requested by the OP or alternatively use something like interpolate() to fill with non-zero values based on the neighboring rows.

Using the INFORMATION_SCHEMA or show databases is not reliable when you do not have enough permissions to see the database. It will seem that the DB does not exist when you just don't have access to it. The creation would then fail afterwards. Another way to have a more precise check is to use the output of the use command, even though I do not know how solid this approach could be (text output change in future versions / other languages...) so be warned.

CHECK=$(mysql -sNe "use DB_NAME" 2>&1)
if [ $? -eq 0 ]; then
  # database exists and is accessible
elif [ ! -z "$(echo $CHECK | grep 'Unknown database')" ]; then
  # database does not exist
elif [ ! -z "$(echo $CHECK | grep 'Access denied')" ]; then
  # cannot tell if database exists (not enough permissions)"
else
  # unexpected output

find . -mindepth 1 -maxdepth 1 -type d | wc -l

For find -mindepth means total number recusive in directories

-maxdepth means total number recusive in directories

-type d means directory

And for wc -l means count the lines of the input

Use list comprehension.

Short circuiting the creation of iterable using a list for example :)

>>> x = [1, 2, 3, 4]
>>> 
>>> k = x.__iter__()
>>> k

[1, 2, 3, 4]
>>> 
>>> z = Set([1,2])
>>> z.update(l)
>>> z
set([1, 2, 3, 4])
>>> 

[Edit: missed the set part of question]

You say it's not working. What are you expecting to happen?

There's no way of getting the data out of a FormData object; it's just intended for you to use to send data along with an XMLHttpRequest object (for the send method).

Update almost five years later: In some newer browsers, this is no longer true and you can now see the data provided to FormData in addition to just stuffing data into it. See the accepted answer for more info.

Here's a code snippet to split a string by n characters separated over lines:

//: A UIKit based Playground for presenting user interface

import UIKit
import PlaygroundSupport

class MyViewController : UIViewController {
    override func loadView() {

        let str = String(charsPerLine: 5, "Hello World!")
        print(str) // "Hello\n Worl\nd!\n"

    }
}

extension String {

    init(charsPerLine:Int, _ str:String){

        self = ""
        var idx = 0
        for char in str {
            self += "\(char)"
            idx = idx + 1
            if idx == charsPerLine {
                self += "\n"
                idx = 0
            }
        }

    }
}

My best solution on R Markdown was to create a code chunk only to load libraries and exclude everything in the chunk.

{r results='asis', echo=FALSE, include=FALSE,}
knitr::opts_chunk$set(echo = TRUE, warning=FALSE)
#formating tables
library(xtable)

#data wrangling
library(dplyr)

#text processing
library(stringi)

You use class media.FaceDetector in android to detect face for free.

This is an example of face detection: https://github.com/betri28/FaceDetectCamera

You can pass semicolon separated values as command argument and then split the string and use it.

<asp:TemplateField ShowHeader="false">
    <ItemTemplate>
       <asp:LinkButton ID="lnkCustomize" Text="Customize"  CommandName="Customize"  CommandArgument='<%#Eval("IdTemplate") + ";" +Eval("EntityId")%>'  runat="server"> 
       </asp:LinkButton>   
    </ItemTemplate>   
</asp:TemplateField>

at server side

protected void gridview_RowCommand(object sender, GridViewCommandEventArgs e)
{
      string[] arg = new string[2];
      arg = e.CommandArgument.ToString().Split(';');
      Session["IdTemplate"] = arg[0];
      Session["IdEntity"] = arg[1];
      Response.Redirect("Samplepage.aspx");
}

Hope it helps!!!!

2020 solution via Material Design Components for Android:

Add Material Components to your gradle setup:

Look for latest version from here: https://maven.google.com/

implementation 'com.google.android.material:material:1.1.0'

or if you havent updated to using AndroidX libs, you can add it this way:

implementation 'com.android.support:design:28.0.0'

Then

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/hint_text"
    app:endIconMode="clear_text">

  <com.google.android.material.textfield.TextInputEditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

</com.google.android.material.textfield.TextInputLayout>

Pay attention to: app:endIconMode="clear_text"

As discussed here Material design docs

IEEE 754 floating point is done in binary. There's no exact conversion from a given number of bits to a given number of decimal digits. 3 bits can hold values from 0 to 7, and 4 bits can hold values from 0 to 15. A value from 0 to 9 takes roughly 3.5 bits, but that's not exact either.

An IEEE 754 double precision number occupies 64 bits. Of this, 52 bits are dedicated to the significand (the rest is a sign bit and exponent). Since the significand is (usually) normalized, there's an implied 53^rd bit.

Now, given 53 bits and roughly 3.5 bits per digit, simple division gives us 15.1429 digits of precision. But remember, that 3.5 bits per decimal digit is only an approximation, not a perfectly accurate answer.

Many (most?) debuggers actually look at the contents of the entire register. On an x86, that's actually an 80-bit number. The x86 floating point unit will normally be adjusted to carry out calculations to 64-bit precision -- but internally, it actually uses a couple of "guard bits", which basically means internally it does the calculation with a few extra bits of precision so it can round the last one correctly. When the debugger looks at the whole register, it'll usually find at least one extra digit that's reasonably accurate -- though since that digit won't have any guard bits, it may not be rounded correctly.

You can create a setTimeout loop using recursion:

function timeout() {
    setTimeout(function () {
        // Do Something Here
        // Then recall the parent function to
        // create a recursive loop.
        timeout();
    }, 1000);
}

The problem with setInterval() and setTimeout() is that there is no guarantee your code will run in the specified time. By using setTimeout() and calling it recursively, you're ensuring that all previous operations inside the timeout are complete before the next iteration of the code begins.

If you download XML file and open it for example in Notepad++ you'll see that encoding is set to something else than UTF8 - I'v had the same problem with xml made myself, and it was just te encoding in the editor :)

String <?xml version="1.0" encoding="UTF-8"?> don't set up the encoding of the document, it's only info for validator or another resource.

Try this simpler one,

cp /home/ankur/folder/file{1,2} /home/ankur/dest

If you want to copy all the 10 files then run this command,

 cp ~/Desktop/{xyz,file{1,2},next,files,which,are,not,similer} foo-bar

use

=VLOOKUP(D4,F4:G9,2)

with the range F4:G9:

0   0.1
1   0.15
5   0.2
15  0.3
30  1
100 1.3

and D4 being the value in question, e.g. 18.75 -> result: 0.3

It would be better to have a check before getting the string.

$newstring = substr($dynamicstring, -7);

if characters are greater then 7 return last 7 characters else return the provided string.

or do this if you need to return message or error if length is less then 7

$newstring = (strlen($dynamicstring)>7)?substr($dynamicstring, -7):"message";

substr documentation

If you don't want to use the CLI and are working on Windows, a very simple solution is to use TortoiseGit, it has the "Delete (keep local)" Action in the menu which works fine.

None is a singleton, therefore identity comparison will always work, whereas an object can fake the equality comparison via .__eq__().

If you want to do it the dirty way, try this.

@SuppressWarnings("unchecked")
public ArrayList<String> convert(ArrayList<Object> a) {
   return (ArrayList) a;
}

Advantage: here you save time by not iterating over all objects.

Disadvantage: may produce a hole in your foot.

It turns out it was too easy. All you have to do is run a cmd as administrator. Then type explorer.exe and hit enter. That opens up Windows Explorer. Now right click on your PowerShell script that you want to run, choose "run with PowerShell" which will launch it in PowerShell in administrator mode.

It may ask you to enable the policy to run, type Y and hit enter. Now the script will run in PowerShell as administrator. In case it runs all red, that means your policy didn't take affect yet. Then try again and it should work fine.

Using os.path.getsize:

>>> import os
>>> b = os.path.getsize("/path/isa_005.mp3")
>>> b
2071611

The output is in bytes.

I just ran into this problem and the actual issue was that I forgot to add a proper application/json header before spitting out the actual JSON data.

header('Content-Type: application/json');

The difference between an array evaluating its values to true or if its empty.

The method empty? comes from the Array class
http://ruby-doc.org/core-2.0.0/Array.html#method-i-empty-3F

It's used to check if the array contains something or not. This includes things that evaluate to false, such as nil and false.

>> a = []
=> []
>> a.empty?
=> true
>> a = [nil, false]
=> [nil, false]
>> a.empty?
=> false
>> a = [nil]
=> [nil]
>> a.empty?
=> false

The method any? comes from the Enumerable module.
http://ruby-doc.org/core-2.0.0/Enumerable.html#method-i-any-3F

It's used to evaluate if "any" value in the array evaluates to true. Similar methods to this are none?, all? and one?, where they all just check to see how many times true could be evaluated. which has nothing to do with the count of values found in a array.

case 1

>> a = []
=> []
>> a.any?
=> false
>> a.one?
=> false
>> a.all?
=> true
>> a.none?
=> true

case 2

>> a = [nil, true]
=> [nil, true]
>> a.any?
=> true
>> a.one?
=> true
>> a.all?
=> false
>> a.none?
=> false

case 3

>> a = [true, true]
=> [true, true]
>> a.any?
=> true
>> a.one?
=> false
>> a.all?
=> true
>> a.none?
=> false

From the LESS website:

If you want to import a CSS file, and don’t want LESS to process it, just use the .css extension:

@import "lib.css"; The directive will just be left as is, and end up in the CSS output.

As jitbit points out in the comments below, this is really only useful for development purposes, as you wouldn't want to have unnecessary @imports consuming precious bandwidth.

There is no built-in method, but there are several ways to do it. The most straightforward way that I can think of at the moment is:

1. Create a subclass of JComponent.
2. Override the paintComponent(Graphics g) method to paint the image that you want to display.
3. Set the content pane of the JFrame to be this subclass.

Some sample code:

class ImagePanel extends JComponent {
    private Image image;
    public ImagePanel(Image image) {
        this.image = image;
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(image, 0, 0, this);
    }
}

// elsewhere
BufferedImage myImage = ImageIO.read(...);
JFrame myJFrame = new JFrame("Image pane");
myJFrame.setContentPane(new ImagePanel(myImage));

Note that this code does not handle resizing the image to fit the JFrame, if that's what you wanted.

You can use Jquery's on method and listen for the scroll event.

This was bugging me too, since this was a standard feature in Sublime Text 2, but somehow automatic indentation no longer worked in Sublime Text 3 for HTML files.

My solution was to find the Miscellaneous.tmPreferences file from Sublime Text 2 (found under %AppData%/Roaming/Sublime Text 2/Packages/HTML) and copy those settings to the same file for ST3.

Now package handling has been made more difficult for ST3, but luckily you can just add the files to your %AppData%/Roaming/Sublime Text 3/Packages folder and they overwrite default settings in the install directory. Just save this file as "%AppData%/Roaming/Sublime Text 3/Packages/HTML/Miscellaneous.tmPreferences" and auto indent works again like it did in ST2.

Regarding,

$ git checkout -b experimental origin/experimental

using

$ git checkout -t origin/experimental

or the more verbose but easier to remember

$ git checkout --track origin/experimental

might be better, in terms of tracking a remote repository.

For top right corner try this:

position: absolute;
top: 0;
right: 0;

Here's an example previously found at androidsnippets.com (the site is currently not maintained anymore).

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

So, you can add your parameters as BasicNameValuePair.

An alternative is to use (Http)URLConnection. See also Using java.net.URLConnection to fire and handle HTTP requests. This is actually the preferred method in newer Android versions (Gingerbread+). See also this blog, this developer doc and Android's HttpURLConnection javadoc.

To not have to worry whether you are running your scripts on Windows, Mac or Linux install the cross-env package. Then you can use your scripts easily, like so:

"scripts": {

Massive props to the developers of this package.

Try this! And never use trigger twice on div!

You can define function to call before the div tag.

$(function(){
    $('div[onload]').trigger('onload');
});

You can use Case expression for returning a boolean in your select query like below.

@Query("SELECT CASE WHEN count(e) > 0 THEN true ELSE false END FROM MyEntity e where e.my_column = ?1")

The commands are adduser and addgroup.

Here's a template for Docker you can use in busybox environments (alpine) as well as Debian-based environments (Ubuntu, etc.):

ENV USER=docker
ENV UID=12345
ENV GID=23456

RUN adduser \
    --disabled-password \
    --gecos "" \
    --home "$(pwd)" \
    --ingroup "$USER" \
    --no-create-home \
    --uid "$UID" \
    "$USER"

Note the following:

• --disabled-password prevents prompt for a password
• --gecos "" circumvents the prompt for "Full Name" etc. on Debian-based systems
• --home "$(pwd)" sets the user's home to the WORKDIR. You may not want this.
• --no-create-home prevents cruft getting copied into the directory from /etc/skel

The usage description for these applications is missing the long flags present in the code for adduser and addgroup.

The following long-form flags should work both in alpine as well as debian-derivatives:

adduser

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: adduser [OPTIONS] USER [GROUP]

Create new user, or add USER to GROUP

        --home DIR           Home directory
        --gecos GECOS        GECOS field
        --shell SHELL        Login shell
        --ingroup GRP        Group (by name)
        --system             Create a system user
        --disabled-password  Don't assign a password
        --no-create-home     Don't create home directory
        --uid UID            User id

One thing to note is that if --ingroup isn't set then the GID is assigned to match the UID. If the GID corresponding to the provided UID already exists adduser will fail.

addgroup

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: addgroup [-g GID] [-S] [USER] GROUP

Add a group or add a user to a group

        --gid GID  Group id
        --system   Create a system group

I discovered all of this while trying to write my own alternative to the fixuid project for running containers as the hosts UID/GID.

My entrypoint helper script can be found on GitHub.

The intent is to prepend that script as the first argument to ENTRYPOINT which should cause Docker to infer UID and GID from a relevant bind mount.

An environment variable "TEMPLATE" may be required to determine where the permissions should be inferred from.

(At the time of writing I don't have documentation for my script. It's still on the todo list!!)

Additionally, if you are debugging as Tom mentioned, you can use var_dump to see the array.

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

The keys are maintained with the removed key missing but they can be rearranged by doing this:

$array = array(1,2,3,4,5);
unset($array[2]);
$arranged = array_values($array);
print_r($arranged);

Outputs:

Array
(
    [0] => 1
    [1] => 2
    [2] => 4
    [3] => 5
)

Notice that if we do the following without rearranging:

unset($array[2]);
$array[]=3;

The index of the value 3 will be 5 because it will be pushed to the end of the array and will not try to check or replace missing index. This is important to remember when using FOR LOOP with index access.

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

1. System.exit() is a method that causes JVM to exit.
2. return just returns the control to calling function.
3. return 8 will return control and value 8 to calling method.

In your tag, simply insert this small line of code.

autocomplete="off"

However, do not place this in the username/email/idname field because if you are still looking to use autocomplete, it will disable it for this field. But I found a way around this, simply place the code in your password input tag because you never autocomplete passwords anyways. This fix should remove the color force, matinain autocomplete ability on your email/username field, and allows you to avoid bulky hacks like Jquery or javascript.

For those in the future looking for a simple way to do this in Razor pages, use the following:

In .cshtml:

@Html.Raw(Html.Encode("<span>blah<span>"))

In .cshtml.cs:

string rawHtml = Html.Raw(Html.Encode("<span>blah<span>"));

var res = exitDictionary
            .Select(p => p.Value).Cast<Dictionary<string, object>>()
            .SelectMany(d => d)
            .Where(p => p.Key == "fieldname1")
            .Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
            .SelectMany(l => l)
            .SelectMany(d=> d)
            .Where(p => p.Key == "valueTitle")
            .Select(p => p.Value)
            .ToList();

This also works, and easy to understand.

In Angular 8 , ViewChild takes 2 parameters:

Try like this:

@ViewChild('nameInput', { static: false }) nameInputRef: ElementRef;

Explanation:

{ static: false }

If you set static false, the child component ALWAYS gets initialized after the view initialization in time for the ngAfterViewInit/ngAfterContentInit callback functions.

{ static: true}

If you set static true, the child component initialization will take place at the view initialization at ngOnInit

By default you can use { static: false }. If you are creating a dynamic view and want to use the template reference variable, then you should use { static: true}

For more info, you can read this article

Working Demo

In the demo, we will scroll to a div using template reference variable.

 @ViewChild("scrollDiv", { static: true }) scrollTo: ElementRef;

With { static: true }, we can use this.scrollTo.nativeElement in ngOnInit, but with { static: false }, this.scrollTo will be undefined in ngOnInit , so we can access in only in ngAfterViewInit

You can do this:

• .html file:

<img src="src/to/your/img.jpg" id="yourImgId"/>

• .js file:

document.getElementById("yourImgId").style.height = "heightpx";

The same you can do with the width.

try this code:

String facebookUrl = "https://www.facebook.com/<id_here>";
        try {
            int versionCode = getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
            if (versionCode >= 3002850) {
                Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
                   startActivity(new Intent(Intent.ACTION_VIEW, uri));
            } else {
                Uri uri = Uri.parse("fb://page/<id_here>");
                startActivity(new Intent(Intent.ACTION_VIEW, uri));
            }
        } catch (PackageManager.NameNotFoundException e) {
            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookUrl)));
        }

To get all the elements starting with "jander" you should use:

$("[id^=jander]")

To get those that end with "jander"

$("[id$=jander]")

See also the JQuery documentation

You can use Cursor like that:

USE master
GO

DECLARE @SQL AS VARCHAR(255)
DECLARE @SPID AS SMALLINT
DECLARE @Database AS VARCHAR(500)
SET @Database = 'AdventureWorks2016CTP3'

DECLARE Murderer CURSOR FOR
SELECT spid FROM sys.sysprocesses WHERE DB_NAME(dbid) = @Database

OPEN Murderer

FETCH NEXT FROM Murderer INTO @SPID
WHILE @@FETCH_STATUS = 0

    BEGIN
    SET @SQL = 'Kill ' + CAST(@SPID AS VARCHAR(10)) + ';'
    EXEC (@SQL)
    PRINT  ' Process ' + CAST(@SPID AS VARCHAR(10)) +' has been killed'
    FETCH NEXT FROM Murderer INTO @SPID
    END 

CLOSE Murderer
DEALLOCATE Murderer

I wrote about that in my blog here: http://www.pigeonsql.com/single-post/2016/12/13/Kill-all-connections-on-DB-by-Cursor

Since Spring 2.5 there's a very easy (and elegant) way to achieve that.

You can just change the params proxyMode and value of the @Scope annotation.

With this trick you can avoid to write extra code or to inject the ApplicationContext every time that you need a prototype inside a singleton bean.

Example:

@Service 
@Scope(value="prototype", proxyMode=ScopedProxyMode.TARGET_CLASS)  
public class LoginAction {}

With the config above LoginAction (inside HomeController) is always a prototype even though the controller is a singleton.

You could have the ViewModel expose an event that the View registers to. Then, when the ViewModel decides its time to close the view, it fires that event which causes the view to close. If you want a specific result value passed back, then you would have a property in the ViewModel for that.

None of the configuration above worked for me on my CentOS 7 server. After hours of searching, that what worked for me:

Edit file phpMyAdmin.conf

sudo nano /etc/httpd/conf.d/phpMyAdmin.conf

And replace the existing <Directory> ... </Directory> node with the following:

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
       Require all granted
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     Deny from All
     Allow from 127.0.0.1
     Allow from ::1
   </IfModule>
</Directory>

I usually use this code to add horizontal line:

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@android:color/darker_gray"/>

To add vertical separator, switch the layout_width and layout_height values

In Python 3.5 or later, using pathlib you can copy text file contents into a variable and close the file in one line:

from pathlib import Path
txt = Path('data.txt').read_text()

and then you can use str.replace to remove the newlines:

txt = txt.replace('\n', '')

Updated Answer (10 Feb 2013)

rmarkdown package: There is now an rmarkdown package available on github that interfaces with Pandoc. It includes a render function. The documentation makes it pretty clear how to convert rmarkdown to pdf among a range of other formats. This includes including output formats in the rmarkdown file or running supplying an output format to the rend function. E.g.,

render("input.Rmd", "pdf_document")

Command-line: When I run render from the command-line (e.g., using a makefile), I sometimes have issues with pandoc not being found. Presumably, it is not on the search path. The following answer explains how to add pandoc to the R environment.

So for example, on my computer running OSX, where I have a copy of pandoc through RStudio, I can use the following:

Rscript -e "Sys.setenv(RSTUDIO_PANDOC='/Applications/RStudio.app/Contents/MacOS/pandoc');library(rmarkdown);  library(utils); render('input.Rmd', 'pdf_document')"

Old Answer (circa 2012)

So, a number of people have suggested that Pandoc is the way to go. See notes below about the importance of having an up-to-date version of Pandoc.

Using Pandoc

I used the following command to convert R Markdown to HTML (i.e., a variant of this makefile), where RMDFILE is the name of the R Markdown file without the .rmd component (it also assumes that the extension is .rmd and not .Rmd).

RMDFILE=example-r-markdown  
Rscript -e "require(knitr); require(markdown); knit('$RMDFILE.rmd', '$RMDFILE.md'); markdownToHTML('$RMDFILE.md', '$RMDFILE.html', options=c('use_xhml'))"

and then this command to convert to pdf

Pandoc -s example-r-markdown.html -o example-r-markdown.pdf

• I removed the reference in the example file which exports plots to imgur to host images.
• I removed a reference to an image that was hosted on imgur. Figures appear to need to be local.
• The options in the markdownToHTML function meant that image references are to files and not to data stored in the HTML file (i.e., I removed 'base64_images' from the option list).
• The resulting output looked like this. It has clearly made a very LaTeX style document in contrast to what I get if I print the HTML file to pdf from a browser.

Getting up-to-date version of Pandoc

As mentioned by @daroczig, it's important to have an up-to-date version of Pandoc in order to output pdfs. On Ubuntu as of 15th June 2012, I was stuck with version 1.8.1 of Pandoc in the package manager, but it seems from the change log that for pdf support you need at least version 1.9+ of Pandoc.

Thus, I installed caball-install. And then ran:

cabal update
cabal install pandoc

Pandoc was installed in ~/.cabal/bin/pandoc Thus, when I ran pandoc it was still seeing the old version. See here for adding to the path.

Because it's not actually a dictionary; it's another mapping type that looks like a dictionary. Use type() to verify. Pass it to dict() to get a real dictionary from it.

Open Chrome Dev Tools or equivalent and run require('React').version in the console.

That works on websites like Facebook as well to find out what version they are using.

SQL Server:

select * from table
except
select top N * from table

Oracle up to 11.2:

select * from table
minus
select * from table where rownum <= N

with TableWithNum as (
    select t.*, rownum as Num
    from Table t
)
select * from TableWithNum where Num > N

Oracle 12.1 and later (following standard ANSI SQL)

select *
from table
order by some_column 
offset x rows
fetch first y rows only

They may meet your needs more or less.

There is no direct way to do what you want by SQL. However, it is not a design flaw, in my opinion.

SQL is not supposed to be used like this.

In relational databases, a table represents a relation, which is a set by definition. A set contains unordered elements.

Also, don't rely on the physical order of the records. The row order is not guaranteed by the RDBMS.

If the ordering of the records is important, you'd better add a column such as `Num' to the table, and use the following query. This is more natural.

select * 
from Table 
where Num > N
order by Num

<a onclick="jsfunction()" href="#">

or

<a onclick="jsfunction()" href="javascript:void(0);">

Edit:

The above response is really not a good solution, having learned a lot about JS since I initially posted. See EndangeredMassa's answer below for the better approach to solving this problem.

If you like GUIs, you can use gitk:

1. start gitk with:

   gitk /path/to/file
   

2. Choose the revision in the top part of the screen, e.g. by description or date. By default, the lower part of the screen shows the diff for that revision, (corresponding to the "patch" radio button).

3. To see the file for the selected revision:

   • Click on the "tree" radio button. This will show the root of the file tree at that revision.
   • Drill down to your file.

insertRow2 <- function(existingDF, newrow, r) {
  existingDF <- rbind(existingDF,newrow)
  existingDF <- existingDF[order(c(1:(nrow(existingDF)-1),r-0.5)),]
  row.names(existingDF) <- 1:nrow(existingDF)
  return(existingDF)  
}

insertRow2(existingDF,newrow,r)

The accepted answer does not seem quite right to me. There is no point dragging a different version of HttpMime when one can depend on the same version of it.

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5'
compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') {
    exclude module: 'org.apache.httpcomponents:httpclient'
}

I had this problem in my main project when I referenced a dll file.

The problem was that the main project that referenced the dll was targeting a lower framework version than that of the dll.

So I upped my target framework version (Right-click project -> Application -> Target framework) and the error disappeared.

Either of this can do it (df is the name of the DataFrame):

Method 1: Using the len function:

len(df) will give the number of rows in a DataFrame named df.

Method 2: using count function:

df[col].count() will count the number of rows in a given column col.

df.count() will give the number of rows for all the columns.

The problem was that the working copy was checked out via svn+ssh (thanks, Thomas). Instead of setting up ssh keys as was suggested, I just checked out a new working copy using svn://domain.com/path/to/repo rather than svn+ssh://domain.com/path/to/repo. Because this working copy is on the same machine as the repository itself, I'm not really missing out on anything, and I can now use the --password and --username options gratuitously. Seems obvious now that I think about it.

To automatically fix all android to androidx issues for React Native (prerequisite npx)

Add the following two flags to true in your gradle.properties file at ProjectFolder/android/gradle.properties

android.useAndroidX=true
android.enableJetifier=true

Execute

npm install --save-dev jetifier
npx jetify
npx react-native run-android

In your package.json add the following to scripts

  "postinstall" : "npx jetify"

More info at https://github.com/mikehardy/jetifier

Update: This is now in-built in react-native 0.60. If you migrate to react-native 0.60 you won't need this step. - https://facebook.github.io/react-native/blog/2019/07/03/version-60#androidx-support

The difference between Slice() and Splice() javascript build-in functions is, Slice returns removed item but did not change the original array ; like,

        // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.slice(index)
        // result=4  
        // after slicing=>  array =[1,2,3,4,5]  (same as original array)

but in splice() case it affects original array; like,

         // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.splice(index)
        // result=4  
        // after splicing array =[1,2,3,5]  (splicing affects original array)

Actually I did it by uncommenting extension=php_curl.dll in the xampp\apache\bin\php.ini file.

I think the only way of doing this in SQL-Server 2008R2 is to use a correlated subquery, or an outer apply:

SELECT  datekey,
        COALESCE(RunningTotal, 0) AS RunningTotal,
        COALESCE(RunningCount, 0) AS RunningCount,
        COALESCE(RunningDistinctCount, 0) AS RunningDistinctCount
FROM    document
        OUTER APPLY
        (   SELECT  SUM(Amount) AS RunningTotal,
                    COUNT(1) AS RunningCount,
                    COUNT(DISTINCT d2.dateKey) AS RunningDistinctCount
            FROM    Document d2
            WHERE   d2.DateKey <= document.DateKey
        ) rt;

This can be done in SQL-Server 2012 using the syntax you have suggested:

SELECT  datekey,
        SUM(Amount) OVER(ORDER BY DateKey) AS RunningTotal
FROM    document

However, use of DISTINCT is still not allowed, so if DISTINCT is required and/or if upgrading isn't an option then I think OUTER APPLY is your best option

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

I decided to download the assigned port numbers from IANA, filter out the used ports, and sort each "Unassigned" range in order of most ports available, descending. This did not work, since the csv file has ranges marked as "Unassigned" that overlap other port number reservations. I manually expanded the ranges of assigned port numbers, leaving me with a list of all assigned port numbers. I then sorted that list and generated my own list of unassigned ranges.

Since this stackoverflow.com page ranked very high in my search about the topic, I figured I'd post the largest ranges here for anyone else who is interested. These are for both TCP and UDP where the number of ports in the range is at least 500.

I have used ajax load to do this:

$('#user_content').load('@Url.Action("UserDetails","User")');

@tennisgent's solution is great. However, I think is a little limited.

Modularity and Encapsulation in Angular goes beyond routes. Based on the way the web is moving towards component-based development, it is important to apply this in directives as well.

As you already know, in Angular we can include templates (structure) and controllers (behavior) in pages and components. AngularCSS enables the last missing piece: attaching stylesheets (presentation).

For a full solution I suggest using AngularCSS.

1. Supports Angular's ngRoute, UI Router, directives, controllers and services.
2. Doesn't required to have ng-app in the <html> tag. This is important when you have multiple apps running on the same page
3. You can customize where the stylesheets are injected: head, body, custom selector, etc...
4. Supports preloading, persisting and cache busting
5. Supports media queries and optimizes page load via matchMedia API

https://github.com/door3/angular-css

Here are some examples:

Routes

  $routeProvider
    .when('/page1', {
      templateUrl: 'page1/page1.html',
      controller: 'page1Ctrl',
      /* Now you can bind css to routes */
      css: 'page1/page1.css'
    })
    .when('/page2', {
      templateUrl: 'page2/page2.html',
      controller: 'page2Ctrl',
      /* You can also enable features like bust cache, persist and preload */
      css: {
        href: 'page2/page2.css',
        bustCache: true
      }
    })
    .when('/page3', {
      templateUrl: 'page3/page3.html',
      controller: 'page3Ctrl',
      /* This is how you can include multiple stylesheets */
      css: ['page3/page3.css','page3/page3-2.css']
    })
    .when('/page4', {
      templateUrl: 'page4/page4.html',
      controller: 'page4Ctrl',
      css: [
        {
          href: 'page4/page4.css',
          persist: true
        }, {
          href: 'page4/page4.mobile.css',
          /* Media Query support via window.matchMedia API
           * This will only add the stylesheet if the breakpoint matches */
          media: 'screen and (max-width : 768px)'
        }, {
          href: 'page4/page4.print.css',
          media: 'print'
        }
      ]
    });

Directives

myApp.directive('myDirective', function () {
  return {
    restrict: 'E',
    templateUrl: 'my-directive/my-directive.html',
    css: 'my-directive/my-directive.css'
  }
});

Additionally, you can use the $css service for edge cases:

myApp.controller('pageCtrl', function ($scope, $css) {

  // Binds stylesheet(s) to scope create/destroy events (recommended over add/remove)
  $css.bind({ 
    href: 'my-page/my-page.css'
  }, $scope);

  // Simply add stylesheet(s)
  $css.add('my-page/my-page.css');

  // Simply remove stylesheet(s)
  $css.remove(['my-page/my-page.css','my-page/my-page2.css']);

  // Remove all stylesheets
  $css.removeAll();

});

Article on Programming.Guide: Switch on enum

enum MyEnum { CONST_ONE, CONST_TWO }

class Test {
        public static void main(String[] args) {
            MyEnum e = MyEnum.CONST_ONE;

            switch (e) {
                case CONST_ONE: System.out.println(1); break;
                case CONST_TWO: System.out.println(2); break;
            }
        }
    }

Switches for strings are implemented in Java 7.

Are you using Windows? Just set the environment variable http_proxy...

set http_proxy=http://your-proxy-address.com:port

... and bower will pick this up. Rather than dealing with a unique config file in your project folder - right? (side-note: when-the-F! will windows allow us to create a .file using explorer? c'mon windows!)

You have to use a Class instance because of the generic type erasure during compilation.

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
    try {
        return clazz.cast(o);
    } catch(ClassCastException e) {
        return null;
    }
}

The declaration of that method is:

public T cast(Object o)

This can also be used for array types. It would look like this:

final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);

Note that when someObject is passed to convertToInstanceOfObject it has the compile time type Object.

Your countLines(String filename) method throws IOException.

You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args) method.

Your main(String[] args) method will get the IOException thrown to it by countLines and it will need to handle or declare it.

Try this to just throw the IOException from main

public class MyClass {
  private int lineCount;
  public static void main(String[] args) throws IOException {
    lineCount = LineCounter.countLines(sFileName);
  }
}

or this to handle it and wrap it in an unchecked IllegalArgumentException:

public class MyClass {
  private int lineCount;
  private String sFileName  = "myfile";
  public static void main(String[] args) throws IOException {
    try {
      lineCount = LineCounter.countLines(sFileName);
     } catch (IOException e) {
       throw new IllegalArgumentException("Unable to load " + sFileName, e);
     }
  }
}

After SqlCommand cmd=new SqlCommand ("insert into time(project,iteration)values('.... Add

cmd.Connection = conn;

Depending on the data (e.g. tsv extension) it may use tab as separators, so you may try sep = '\t' with read.csv.

If the label immediately follows a specified input element:

input#example + label { ... }
input:checked + label { ... }

You cannot use AppSettings static object for this. Try this

string appPath = System.IO.Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly().Location);          
string configFile = System.IO.Path.Combine(appPath, "App.config");
ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap();         
configFileMap.ExeConfigFilename = configFile;          
System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);

config.AppSettings.Settings["YourThing"].Value = "New Value"; 
config.Save(); 

The transmission delay is the amount of time required for the router to push out the packet, it has nothing to do with the distance between the two routers. The propagation delay is the time taken by a bit to to propagate form one router to the next

If you are looking for an expression returning true for two NULLs you can use:

SELECT 1 
WHERE EXISTS (
    SELECT NULL
    INTERSECT
    SELECT NULL
)

It is helpful if you want to replicate data from one table to another.

casting works, but it is a pain, so I would recommend using spioter's method unless you are using a lot of truly blob data.

SELECT CAST(OLD_PASSWORD("test") AS CHAR)

You can also cast as other types, and even restrict the size, but most of the time I just use CHAR: http://dev.mysql.com/doc/refman/5.5/en/cast-functions.html#function_cast

I had this problem with innerHTML, I had to append a Hotjar script to the "head" tag of my Reactjs application and it would have to execute right after appending.

One of the good solutions for dynamic Node import into the "head" tag is React-helment module.

Also, there is a useful solution for the proposed issue:

No script tags in innerHTML!

It turns out that HTML5 does not allow script tags to be dynamically added using the innerHTML property. So the following will not execute and there will be no alert saying Hello World!

element.innerHTML = "<script>alert('Hello World!')</script>";

This is documented in the HTML5 spec:

Note: script elements inserted using innerHTML do not execute when they are inserted.

But beware, this doesn't mean innerHTML is safe from cross-site scripting. It is possible to execute JavaScript via innerHTML without using tags as illustrated on MDN's innerHTML page.

Solution: Dynamically adding scripts

To dynamically add a script tag, you need to create a new script element and append it to the target element.

You can do this for external scripts:

var newScript = document.createElement("script");
newScript.src = "http://www.example.com/my-script.js";
target.appendChild(newScript);

And inline scripts:

var newScript = document.createElement("script");
var inlineScript = document.createTextNode("alert('Hello World!');");
newScript.appendChild(inlineScript); 
target.appendChild(newScript);

Vector is a broken class that is not threadsafe, despite it being "synchronized" and is only used by students and other inexperienced programmers.

ArrayList is the go-to List implementation used by professionals and experienced programmers.

Professionals wanting a threadsafe List implementation use a CopyOnWriteArrayList.

I have fixed this problem when calling a MVC3 Controller. I added:

Response.AddHeader("Access-Control-Allow-Origin", "*"); 

before my

return Json(model, JsonRequestBehavior.AllowGet);

And also my $.ajax was complaining that it does not accept Content-type header in my ajax call, so I commented it out as I know its JSON being passed to the Action.

Hope that helps.

I had similar problem with the data frame:

group time weight.loss
1 Control  wl1    4.500000
2    Diet  wl1    5.333333
3  DietEx  wl1    6.200000
4 Control  wl2    3.333333
5    Diet  wl2    3.916667
6  DietEx  wl2    6.100000
7 Control  wl3    2.083333
8    Diet  wl3    2.250000
9  DietEx  wl3    2.200000

I think the variable for x axis should be numeric, so that geom_line knows how to connect the points to draw the line.

after I change the 2nd column to numeric:

 group time weight.loss
1 Control    1    4.500000
2    Diet    1    5.333333
3  DietEx    1    6.200000
4 Control    2    3.333333
5    Diet    2    3.916667
6  DietEx    2    6.100000
7 Control    3    2.083333
8    Diet    3    2.250000
9  DietEx    3    2.200000

then it works.

I was receiving sqlite locks as well in a C# .NET 4.6.1 app I built when it was trying to write data, but not when running the app in Visual Studio on my dev machine. Instead it was only happening when the app was installed and running on a remote Windows 10 machine.

Initially I thought it was file system permissions, however it turns out that the System.Data.SQLite package drivers (v1.0.109.2) I installed in the project using Nuget were causing the problem. I removed the NuGet package, and manually referenced an older version of the drivers in the project, and once the app was reinstalled on the remote machine the locking issues magically disappeared. Can only think there was a bug with the latest drivers or the Nuget package.

No. They don't inherit it.

The fact some other class may use it indirectly says nothing about inheritance, but about encapsulation.

For instance:

class Some { 
   private int count; 
   public void increment() { 
      count++;
   }
   public String toString() { 
       return Integer.toString( count );
   }
}

class UseIt { 
    void useIt() { 
        Some s = new Some();
        s.increment();
        s.increment();
        s.increment();
        int v = Integer.parseInt( s.toString() );
        // hey, can you say you inherit it?
     }
}

You can also get the value of count inside UseIt via reflection. It doesn't means, you inherit it.

UPDATE

Even though the value is there, it is not inherited by the subclass.

For instance a subclass defined as:

class SomeOther extends Some { 
    private int count = 1000;
    @Override
    public void increment() { 
        super.increment();
        count *= 10000;
    }
}

class UseIt { 
    public static void main( String ... args ) { 
        s = new SomeOther();
        s.increment();
        s.increment();
        s.increment();
        v = Integer.parseInt( s.toString() );
        // what is the value of v?           
     }
}

This is exactly the same situation as the first example. The attribute count is hidden and not inherited by the subclass at all. Still, as DigitalRoss points out, the value is there, but not by means on inheritance.

Put it this way. If your father is wealthy and gives you a credit card, you can still buy thing with his money, but doesn't mean you have inherited all that money, does it?

Other update

It is very interesting though, to know why the attribute is there.

I frankly don't have the exact term to describe it, but it's the JVM and the way it works that loads also the "not inherited" parent definition.

We could actually change the parent and the subclass will still work.

For instance:

//A.java
class A {
   private int i;
   public String toString() { return ""+ i; }
}
// B.java
class B extends A {}
// Main.java
class Main {
   public static void main( String [] args ) {
      System.out.println( new B().toString() );
    }
}
// Compile all the files
javac A.java B.java Main.java
// Run Main
java Main
// Outout is 0 as expected as B is using the A 'toString' definition
0

// Change A.java
class A {
   public String toString() {
      return "Nothing here";
   }
}
// Recompile ONLY A.java
javac A.java
java Main
// B wasn't modified and yet it shows a different behaviour, this is not due to 
// inheritance but the way Java loads the class
Output: Nothing here

I guess the exact term could be found here: The JavaTM Virtual Machine Specification

One option could be converting DateTime to ToUniversalTime() before converting to string using "o" format. For example,

var dt = DateTime.Now.ToUniversalTime();
Console.WriteLine(dt.ToString("o"));

It will output:

2016-01-31T20:16:01.9092348Z

$keys = array_keys($arr);
$keys = rsort($keys);

print $keys[0];

should print "10"

Here is a query, you can run it in SQL Developer (or SQL*Plus):

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
  FROM DBA_SEGMENTS DS
  WHERE SEGMENT_NAME IN (SELECT TABLE_NAME FROM DBA_TABLES)
 GROUP BY DS.TABLESPACE_NAME,
       SEGMENT_NAME;

This is an article about your problem. Adding a thousands-seperator is not built in to JavaScript, so you'll have to write your own function like this (example taken from the linked page):

function addSeperator(nStr){
  nStr += '';
  x = nStr.split('.');
  x1 = x[0];
  x2 = x.length > 1 ? '.' + x[1] : '';
  var rgx = /(\d+)(\d{3})/;
  while (rgx.test(x1)) {
    x1 = x1.replace(rgx, '$1' + ',' + '$2');
  }
  return x1 + x2;
}

Sounds like a good opportunity to use an AlertDialog.

As basic as it seems, Android does not have a built-in dialog to do this (as far as I know). Fortunately, it's just a little extra work on top of creating a standard AlertDialog. You simply need to create an EditText for the user to input data, and set it as the view of the AlertDialog. You can customize the type of input allowed using setInputType, if you need.

If you're able to use a member variable, you can simply set the variable to the value of the EditText, and it will persist after the dialog has dismissed. If you can't use a member variable, you may need to use a listener to send the string value to the right place. (I can edit and elaborate more if this is what you need).

Within your class:

private String m_Text = "";

Within the OnClickListener of your button (or in a function called from there):

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Title");

// Set up the input
final EditText input = new EditText(this);
// Specify the type of input expected; this, for example, sets the input as a password, and will mask the text
input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
builder.setView(input);

// Set up the buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
    @Override
    public void onClick(DialogInterface dialog, int which) {
        m_Text = input.getText().toString();
    }
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        dialog.cancel();
    }
});

builder.show();

String str = "www.anywebsite.com/folder/subfolder/directory";
int index = str.lastIndexOf('/');
String lastString = str.substring(index +1);

Now lastString has the value "directory"

I had this issue today which was solved by selecting Product -> Clean. I was so confused since my code was proper. The problem started from using command-Z too many times :)

If you want your dates to conform a particular format or formats then use DateTime.TryParseExact otherwise that is the default behaviour of DateTime.TryParse

DateTime.TryParse

This method tries to ignore unrecognized data, if possible, and fills in missing month, day, and year information with the current date. If s contains only a date and no time, this method assumes the time is 12:00 midnight. If s includes a date component with a two-digit year, it is converted to a year in the current culture's current calendar based on the value of the Calendar.TwoDigitYearMax property. Any leading, inner, or trailing white space character in s is ignored.

If you want to confirm against multiple formats then look at DateTime.TryParseExact Method (String, String[], IFormatProvider, DateTimeStyles, DateTime) overload. Example from the same link:

string[] formats= {"M/d/yyyy h:mm:ss tt", "M/d/yyyy h:mm tt", 
                   "MM/dd/yyyy hh:mm:ss", "M/d/yyyy h:mm:ss", 
                   "M/d/yyyy hh:mm tt", "M/d/yyyy hh tt", 
                   "M/d/yyyy h:mm", "M/d/yyyy h:mm",

use the xclip which is command line interface to X selections

install

apt-get install xclip

usage

echo "test xclip " > /tmp/test.xclip
xclip -i < /tmp/test.xclip
xclip -o > /tmp/test.xclip.out

cat /tmp/test.xclip.out   # "test xclip"

enjoy.

Pyromancer's answer seems pretty good to me, but maybe you wanted:

DateTime.Now.Millisecond

But if you are comparing dates, TimeSpan is the way to go.

You can get annotations on the getter method:

propertyDescriptor.getReadMethod().getDeclaredAnnotations();

Getting the annotations of a private field seems like a bad idea... what if the property isn't even backed by a field, or is backed by a field with a different name? Even ignoring those cases, you're breaking abstraction by looking at private stuff.

It's a surprisingly little-known feature of C++ (as evidenced by the fact that no-one has given this as an answer yet), but it actually has special syntax for value-initializing an array:

new int[10]();

Note that you must use the empty parentheses — you cannot, for example, use (0) or anything else (which is why this is only useful for value initialization).

This is explicitly permitted by ISO C++03 5.3.4[expr.new]/15, which says:

A new-expression that creates an object of type T initializes that object as follows:

...

• If the new-initializer is of the form (), the item is value-initialized (8.5);

and does not restrict the types for which this is allowed, whereas the (expression-list) form is explicitly restricted by further rules in the same section such that it does not allow array types.

Google already published a guide on optimization of PHP and the conclusion was:

No getter and setter Optimizing PHP

And no, you must not use magic methods. For PHP, Magic Method are evil. Why?

1. They are hard to debug.
2. There is a negative performance impact.
3. They require writing more code.

PHP is not Java, C++, or C#. PHP is different and plays with different roles.

If, running an Oracle HotSpot JDK 1.7.x, on a Linux platform where your locale suggests UTF-8 (e.g. LANG=en_US.utf8), if you don't set it on the command-line with -Dfile.encoding, the JDK will default file.encoding and the default Charset like this:

System.out.println(String.format("file.encoding: %s", System.getProperty("file.encoding")));
System.out.println(String.format("defaultCharset: %s", Charset.defaultCharset().name()));

... yields:

file.encoding: UTF-8
defaultCharset: UTF-8

... suggesting the default is UTF-8 on such a platform.

Additionally, if java.nio.charset.Charset.defaultCharset() finds file.encoding not-set, it looks for java.nio.charset.Charset.forName("UTF-8"), suggesting it prefers that string, although it is well-aliased, so "UTF8" will also work fine.

If you run the same program on the same platform with java -Dfile.encoding=UTF8, without the hypen, it yields:

file.encoding: UTF8
defaultCharset: UTF-8

... noting that the default charset has been canonicalized from UTF8 to UTF-8.

Use the command

git clone --help

to see whether your git supports the command

git clone --branch tag_name

If not, just do the following:

Update for laravel 5.4 ----

All answers have have used the HTML class for laravel but I guess it has been depreciated now in laravel 5.4, so Put your css and js files in public->css/js And reference them in your html using

<link href="css/css.common.css" rel="stylesheet" >

You are trying to index into a scalar (non-iterable) value:

[y[1] for y in y_test]
#  ^ this is the problem

When you call [y for y in test] you are iterating over the values already, so you get a single value in y.

Your code is the same as trying to do the following:

y_test = [1, 2, 3]
y = y_test[0] # y = 1
print(y[0]) # this line will fail

I'm not sure what you're trying to get into your results array, but you need to get rid of [y[1] for y in y_test].

If you want to append each y in y_test to results, you'll need to expand your list comprehension out further to something like this:

[results.append(..., y) for y in y_test]

Or just use a for loop:

for y in y_test:
    results.append(..., y)

What type() means:

I think your question is a bit more general than I originally thought. type() with one argument returns the type or class of the object. So if you have a = 'abc' and use type(a) this returns str because the variable a is a string. If b = 10, type(b) returns int.

See also python documentation on type().

For comparisons:

If you want a comparison you could use: if type(v) == h5py.h5r.Reference (to check if it is a h5py.h5r.Reference instance).

But it is recommended that one uses if isinstance(v, h5py.h5r.Reference) but then also subclasses will evaluate to True.

If you want to print the class use print v.__class__.__name__.

More generally: You can compare if two instances have the same class by using type(v) is type(other_v) or isinstance(v, other_v.__class__).

agree to most answers except that in jupyter_notebook_config.py, you have to put

It is possible to use full C# 6.0 features in Visual Studio 2013 if you have Resharper.
You have to enable Resharper Build and voilá! In Resharper Options -> Build - enable Resharper Build and in "Use MSBuild.exe version" choose "Latest Installed"

This way Resharper is going to build your C# 6.0 Projects and will also not underline C# 6.0 code as invalid.

I am also using this although I have Visual Studio 2015 because:

1. Unit Tests in Resharper don't work for me with Visual Studio 2015 for some reason
2. VS 2015 uses a lot more memory than VS 2013.

I am putting this here, as I was looking for a solution for this problem for some time now and maybe it will help someone else.

In Visual Studio 2005 Pro:

Ctrl + E, Ctrl + W

Or menu Edit ? Advanced ? Word Wrap.

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

I used the following article on MSDN to solve this issue (in this case from MVC 4 to MVC 5)

https://docs.microsoft.com/en-us/aspnet/mvc/overview/releases/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2

Main extracts from the article are:

Main Web.config (Not the one in the Views folder)

In the runtime block update System.Web.Mvc to 5.0.0.0 ,System.Web.Helpers to 3.0.0.0 and System.Web.WebPages to 3.0.0.0

<dependentAssembly>
  <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

<dependentAssembly>
  <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

<dependentAssembly>
  <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

Then look for the appsettings block and update the webpages:Version value to 3.0.0.0

<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
</appSettings>

Views Web.config

Update the host factoryType block to System.Web.Mvc to 5.0.0.0

<system.web.webPages.razor>
   <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
   <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
         <add namespace="System.Web.Mvc" />
      </namespaces>
   </pages>
</system.web.webPages.razor>

Then under the pages block update any references to System.Web.Mvc to 5.0.0.0

    <pages
      validateRequest="false"
      pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
    <controls>
      <add assembly="System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />
    </controls>
  </pages>

And finally under the configuration block update the System.Web references to 3.0.0.0

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

@Fox: great answer! Here's a bit of an extension with some more options. It's what I've been using lately as a go-to solution:

var fs = require('fs');

fs.lstat( targetPath, function (err, inodeStatus) {
  if (err) {

    // file does not exist-
    if (err.code === 'ENOENT' ) {
      console.log('No file or directory at',targetPath);
      return;
    }

    // miscellaneous error (e.g. permissions)
    console.error(err);
    return;
  }


  // Check if this is a file or directory
  var isDirectory = inodeStatus.isDirectory();


  // Get file size
  //
  // NOTE: this won't work recursively for directories-- see:
  // http://stackoverflow.com/a/7550430/486547
  //
  var sizeInBytes = inodeStatus.size;

  console.log(
    (isDirectory ? 'Folder' : 'File'),
    'at',targetPath,
    'is',sizeInBytes,'bytes.'
  );


}

P.S. check out fs-extra if you aren't already using it-- it's pretty sweet. https://github.com/jprichardson/node-fs-extra)

Or you could use dsquery and dsget:

dsquery user domainroot -name <userName> | dsget user -memberof

To retrieve group memberships something like this:

The limit of the enhanced format notifications is documented here.

It explicitly states:

The payload must not exceed 256 bytes and must not be null-terminated.

ascandroli claims above that they were able to send messages with 1400 characters. My own testing with the new notification format showed that a message just 1 byte over the 256 byte limit was rejected. Given that the docs are very explicit on this point I suggest it is safer to use 256 regardless of what you may be able to achieve experimentally as there is no guarantee Apple won't change it to 256 in the future.

As for the alert text itself, if you can fit it in the 256 total payload size then it will be displayed by iOS. They truncate the message that shows up on the status bar, but if you open the notification center, the entire message is there. It even renders newline characters \n.

Format won't be completely the same, but it does write the data to a text file, and R will be able to reread it using dget when you want to retrieve it again as a list.

Based on this page:

• Run regedit (remember to run it as the administrator)
• Expand HKEY_LOCAL_MACHINE
• Expand SOFTWARE
• Expand Microsoft
• Expand Windows
• Expand CurrentVersion
• Expand App Paths
• At App Paths, add a new KEY called sqldeveloper.exe
• Expand sqldeveloper.exe
• Modify the (DEFAULT) value to the full pathway to the sqldeveloper executable (See example below step 11)
• Create a new STRING VALUE called PATH and set it value to the sqldeveloper pathway + \jdk\jre\bin

Here are some screenshots to make this easy.

The reason that the compiler lets you cast the object returned from JSON.parse to a class is because typescript is based on structural subtyping.
You don't really have an instance of an Employee, you have an object (as you see in the console) which has the same properties.

A simpler example:

class A {
    constructor(public str: string, public num: number) {}
}

function logA(a: A) {
    console.log(`A instance with str: "${ a.str }" and num: ${ a.num }`);
}

let a1 = { str: "string", num: 0, boo: true };
let a2 = new A("stirng", 0);
logA(a1); // no errors
logA(a2);

(code in playground)

There's no error because a1 satisfies type A because it has all of its properties, and the logA function can be called with no runtime errors even if what it receives isn't an instance of A as long as it has the same properties.

That works great when your classes are simple data objects and have no methods, but once you introduce methods then things tend to break:

class A {
    constructor(public str: string, public num: number) { }

    multiplyBy(x: number): number {
        return this.num * x;
    }
}

// this won't compile:
let a1 = { str: "string", num: 0, boo: true } as A; // Error: Type '{ str: string; num: number; boo: boolean; }' cannot be converted to type 'A'

// but this will:
let a2 = { str: "string", num: 0 } as A;

// and then you get a runtime error:
a2.multiplyBy(4); // Error: Uncaught TypeError: a2.multiplyBy is not a function

(code in playground)

Edit

This works just fine:

const employeeString = '{"department":"<anystring>","typeOfEmployee":"<anystring>","firstname":"<anystring>","lastname":"<anystring>","birthdate":"<anydate>","maxWorkHours":0,"username":"<anystring>","permissions":"<anystring>","lastUpdate":"<anydate>"}';
let employee1 = JSON.parse(employeeString);
console.log(employee1);

(code in playground)

If you're trying to use JSON.parse on your object when it's not a string:

let e = {
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 3,
    "username": "<anystring>",
    "permissions": "<anystring>",
    "lastUpdate": "<anydate>"
}
let employee2 = JSON.parse(e);

Then you'll get the error because it's not a string, it's an object, and if you already have it in this form then there's no need to use JSON.parse.

But, as I wrote, if you're going with this way then you won't have an instance of the class, just an object that has the same properties as the class members.

If you want an instance then:

let e = new Employee();
Object.assign(e, {
    "department": "<anystring>",
    "typeOfEmployee": "<anystring>",
    "firstname": "<anystring>",
    "lastname": "<anystring>",
    "birthdate": "<anydate>",
    "maxWorkHours": 3,
    "username": "<anystring>",
    "permissions": "<anystring>",
    "lastUpdate": "<anydate>"
});

public class Main {
    public static void main(String[] args) {
        int i = 10;
        int j = 20;
        int k = 5;
        int x = (i > j && i > k) ? i : (j > k) ? j : k;
        int y = (i < j && i < k) ? i : (j < k) ? j : k;
        System.out.println("Largetst Number : "+x);
        System.out.println("Smallest Number : "+y);
    }
}

Output:
Largetst Number : 20
Smallest Number : 5

Why don't you use PowerShell?

Hi I hope this will help:

 private PowerManager mPowerManager;
 private PowerManager.WakeLock mWakeLock;

 public void turnOnScreen(){
     // turn on screen
     Log.v("ProximityActivity", "ON!");
     mWakeLock = mPowerManager.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "tag");
     mWakeLock.acquire();
}

 @TargetApi(21) //Suppress lint error for PROXIMITY_SCREEN_OFF_WAKE_LOCK
 public void turnOffScreen(){
     // turn off screen
     Log.v("ProximityActivity", "OFF!");
     mWakeLock = mPowerManager.newWakeLock(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, "tag");
     mWakeLock.acquire();
}

Lets say you want to unstage changes upto n commits,

Where commit hashes are as follows:

• h1
• h2 ...
• hn
• hn+1

Then run the following command:
git reset hn

Now the HEAD will be at hn+1. Changes from h1 to hn will be unstaged.

Easiest way to execute!

set shell=CreateObject("Shell.Application")
' shell.ShellExecute "application", "arguments", "path", "verb", window
shell.ShellExecute  "slipery.bat",,"C:\Users\anthony\Desktop\dvx", "runas", 1
set shell=nothing 

now include bootstrap 4:

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.3/css/bootstrap.min.css');

and code should be like this:

<div class="row">
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">elements 1</div>
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">
         <div class="pull-lg-right pull-xl-right">
            elements 2
         </div>
    </div>
</div>

You want this

document.body.insertAdjacentHTML( 'afterbegin', '<div id="myID">...</div>' );

Be careful, the solution proposed with $a = array_combine($a, $a); will not work for numeric values.

I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384) to be the keys as well as the values however PHP manual states:

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.

So I solved it like this:

foreach($array as $key => $val) {
    $new_array[$val]=$val;
}

References are "hidden pointers" (non-null) to things which can change (lvalues). You cannot define them to a constant. It should be a "variable" thing.

EDIT::

I am thinking of

int &x = y;

as almost equivalent of

int* __px = &y;
#define x (*__px)

where __px is a fresh name, and the #define x works only inside the block containing the declaration of x reference.

You can use this (I didn't try this yet, but I hope this works):

if(startService(someIntent) != null) {
    Toast.makeText(getBaseContext(), "Service is already running", Toast.LENGTH_SHORT).show();
}
else {
    Toast.makeText(getBaseContext(), "There is no service running, starting service..", Toast.LENGTH_SHORT).show();
}

The startService method returns a ComponentName object if there is an already running service. If not, null will be returned.

See public abstract ComponentName startService (Intent service).

This is not like checking I think, because it's starting the service, so you can add stopService(someIntent); under the code.

Think of the window in Windows as being a struct that describes it. This struct is an internal part of Windows and you don't need to know the details of it. Instead, Windows provides a typedef for pointer to struct for that struct. That's the "handle" by which you can get hold on the window.,

This is to keep requesting inputs while this input is integer and find whether it is odd or even else it will end.

int counter = 1;
    System.out.println("Enter a number:");
    Scanner OddInput = new Scanner(System.in);
        while(OddInput.hasNextInt()){
            int Num = OddInput.nextInt();
            if (Num %2==0){
                System.out.println("Number " + Num + " is Even");
                System.out.println("Enter a number:");
            }
            else {
                System.out.println("Number " + Num + " is Odd");
                System.out.println("Enter a number:");
                }
            }
        System.out.println("Program Ended");

To perform case-insensitive operations, supply re.IGNORECASE

>>> import re
>>> test = 'UPPER TEXT, lower text, Mixed Text'
>>> re.findall('text', test, flags=re.IGNORECASE)
['TEXT', 'text', 'Text']

and if we want to replace text matching the case...

>>> def matchcase(word):
        def replace(m):
            text = m.group()
            if text.isupper():
                return word.upper()
            elif text.islower():

Using PowerShell, you can execute this statement:

([system.reflection.assembly]::loadfile("C:\..\Full_Path\..\MyDLL.dll")).FullName

The output will provide the Version, Culture and PublicKeyToken as shown below:

This is a slightly modified solution. The Process will be killed when it was idle for at least 1 second. Maybe you should add a timeof of X seconds and call the function from a separate thread.

private void SendToPrinter()
{
  ProcessStartInfo info = new ProcessStartInfo();
  info.Verb = "print";
  info.FileName = @"c:\output.pdf";
  info.CreateNoWindow = true;
  info.WindowStyle = ProcessWindowStyle.Hidden;

  Process p = new Process();
  p.StartInfo = info;
  p.Start();

  long ticks = -1;
  while (ticks != p.TotalProcessorTime.Ticks)
  {
    ticks = p.TotalProcessorTime.Ticks;
    Thread.Sleep(1000);
  }

  if (false == p.CloseMainWindow())
    p.Kill();
}

given that you're a newbie, I'd say don't try to do this yet. it's definitely possible, but will needlessly complicate your Makefile. stick to the simple ways until you're more comfortable with make.

that said, one way to build in a directory different from the source directory is VPATH; i prefer pattern rules

Using writeLines also allows you to dispense with the "\n" newline character, by using c(). As in:

writeLines(c("File not supplied.","Usage: ./program F=filename",[additional text for third line]))

This is helpful if you plan on writing a multiline message with combined fixed and variable input, such as the [additional text for third line] above.

        alert("Please confirm if everything is correct");
        $("input[type='submit']").val("text 2");
        return false;
    }
});

4. Right click to amd64 => Security => Edit => Add User => Everyone Or Current User => Allow all permissions => OK.
5. Prepare the Commands for each file in text editor as: wsdl.exe E:\YourServiceFileName.wsdl /l:CS /server.
6. Now open Visual studio command prompt from : C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\Shortcuts\VS2013 x64 Native Tools Command Prompt.
7. Execute above command.

8. Go to directory : C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64, Where respective .CS file should be generated.

   9.Move generated CS file to appropriate location.

Disable submit button on form submit

It works fine in Internet Explorer and Firefox without it, but it did not work in Google Chrome.

The problem is that you are disabling the button before it can actually trigger the submit event.

First, let me fix a little bit your declaration:

List<Map<String, List<String>>> listOfMapOfList = 
    new HashList<Map<String, List<String>>>();

Please pay attention that I used concrete class (HashMap) only once. It is important to use interface where you can to be able to change the implementation later.

Now you want to add element to the list, don't you? But the element is a map, so you have to create it:

Map<String, List<String>> mapOfList = new HashMap<String, List<String>>();

Now you want to populate the map. Fortunately you can use utility that creates lists for you, otherwise you have to create list separately:

mapOfList.put("mykey", Arrays.asList("one", "two", "three"));

OK, now we are ready to add the map into the list:

listOfMapOfList.add(mapOfList);

BUT:

Stop creating complicated collections right now! Think about the future: you will probably have to change the internal map to something else or list to set etc. This will probably cause you to re-write significant parts of your code. Instead define class that contains you data and then add it to one-dimentional collection:

Let's call your class Student (just as example):

public Student {
    private String firstName;
    private String lastName;
    private int studentId;

    private Colectiuon<String> courseworks = Collections.emtpyList();

    //constructors, getters, setters etc
}

Now you can define simple collection:

Collection<Student> students = new ArrayList<Student>();

If in future you want to put your students into map where key is the studentId, do it:

Map<Integer, Student> students = new HashMap<Integer, Student>();

pygolang provides sync.WorkGroup which, in particular, propagates exception from spawned worker threads to the main thread. For example:

#!/usr/bin/env python
"""This program demostrates how with sync.WorkGroup an exception raised in
spawned thread is propagated into main thread which spawned the worker."""

from __future__ import print_function
from golang import sync, context

def T1(ctx, *argv):
    print('T1: run ... %r' % (argv,))
    raise RuntimeError('T1: problem')

def T2(ctx):
    print('T2: ran ok')

def main():
    wg = sync.WorkGroup(context.background())
    wg.go(T1, [1,2,3])
    wg.go(T2)

    try:
        wg.wait()
    except Exception as e:
        print('Tmain: caught exception: %r\n' %e)
        # reraising to see full traceback
        raise

if __name__ == '__main__':
    main()

gives the following when run:

T1: run ... ([1, 2, 3],)
T2: ran ok
Tmain: caught exception: RuntimeError('T1: problem',)

Traceback (most recent call last):
  File "./x.py", line 28, in <module>
    main()
  File "./x.py", line 21, in main
    wg.wait()
  File "golang/_sync.pyx", line 198, in golang._sync.PyWorkGroup.wait
    pyerr_reraise(pyerr)
  File "golang/_sync.pyx", line 178, in golang._sync.PyWorkGroup.go.pyrunf
    f(pywg._pyctx, *argv, **kw)
  File "./x.py", line 10, in T1
    raise RuntimeError('T1: problem')
RuntimeError: T1: problem

The original code from the question would be just:

    wg = sync.WorkGroup(context.background())

    def _(ctx):
        shul.copytree(sourceFolder, destFolder)
    wg.go(_)

    # waits for spawned worker to complete and, on error, reraises
    # its exception on the main thread.
    wg.wait()

You can set HTML object's property checked to false like this:

document.getElementById('desiredInput').checked = false;

Example: Hold down Ctrl (? on mac) key to uncheck.

var radios = document.getElementsByTagName('input');
for(i=0; i<radios.length; i++ ) {
    radios[i].onclick = function(e) {
        if(e.ctrlKey || e.metaKey) {
            this.checked = false;
        }
    }
}

<input type="radio" name="test" value="1" />
<input type="radio" name="test" value="2" checked="checked" />
<input type="radio" name="test" value="3" />

The quickest way would be with a pivot table. Make sure your column of data has a header row, highlight the data and the header, from the insert ribbon select pivot table and then drag your header from the pivot table fields list to the row labels and to the values boxes.

I had to play with the widths of my main containers:

    transform: rotate(90deg);

    .content {
      width: calc(155%);
    }
  }
}

Implementations of java.util.Set

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

Android's default system path of your application database is /data/data/YOUR_PACKAGE/databases/YOUR_DB_NAME

Your logcat clearly says Failed to open database '/data/data/com.example.quotes/databasesQuotesdb'

Which means there is no file present on the given path or You have given the wrong path for the data file. As I can see there should be "/" after databases folder.

Your DB_PATH variable should end with a "/".

private static String DB_PATH = "/data/data/com.example.quotes/databases/";

Your correct path will be now "/data/data/com.example.quotes/databases/Quotesdb"

Any JS code which executes and deals with DOM elements should execute after the DOM elements have been created. JS code is interpreted from top to down as layed out in the HTML. So, if there is a tag before the DOM elements, the JS code within script tag will execute as the browser parses the HTML page.

So, in your case, you can put your DOM interacting code inside a function so that only function is defined but not executed.

Then you can add an event listener for document load to execute the function.

That will give you something like:

<script>
  function init() {
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");
    myButton.onclick = function() {
      var userName = myTextfield.value;
      greetUser(userName);
    }
  }

  function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
  }

  document.addEventListener('readystatechange', function() {
    if (document.readyState === "complete") {
      init();
    }
  });

</script>
