For users of GitHub, this worked for me:

1. In any branch protection rules where you wish to make the change, make sure Allow force pushes is enabled
2. git reset --hard <full_hash_of_commit_to_reset_to>
3. git push --force

This will "correct" the branch history on your local machine and the GitHub server, but anyone who has sync'ed this branch with the server since the bad commit will have the history on their local machine. If they have permission to push to the branch directly then these commits will show right back up when they sync.

All everyone else needs to do is the git reset command from above to "correct" the branch on their local machine. Of course they would need to be wary of any local commits made to this branch after the target hash. Cherry pick/backup and reapply those as necessary, but if you are in a protected branch then the number of people who can commit directly to it is likely limited.

You can convert a character from lower case to upper case and vice-versa using bit manipulation as shown below:

#include<stdio.h>
int main(){
  char c;
  printf("Enter a character in uppercase\n");
  scanf("%c",&c);
  c|=' '; // perform or operation on c and ' '
  printf("The lower case of %c is \n",c);
  c&='_'; // perform 'and' operation with '_' to get upper case letter. 
  printf("Back to upper case %c\n",c);   
  return 0;
}

I'm good with Mnementh's recommentation.
Just one caveat though,

 ConcurrentModificationException

Mind that you don't have more than one thread running. This exception could appear if more than one thread executes, and the threads are not well synchronized.

do a :

git branch

if git show you something like :

* (no branch)
master
Dbranch

You have a "detached HEAD". If you have modify some files on this branch you, commit them, then return to master with

git checkout master 

Now you should be able to delete the Dbranch.

It works in Kotlin after buildDrawingCache() being deprecated

 // convert imageView to bitmap
val bitmap = (imageViewId.getDrawable() as BitmapDrawable).getBitmap()

This is the format I used to exclude some paths:

$ find ./ -type f -name "pattern" ! -path "excluded path" ! -path "excluded path"

I used this to find all files not in ".*" paths:

$ find ./ -type f -name "*" ! -path "./.*" ! -path "./*/.*"

Since ES6 filter supports pointy arrow notation (like LINQ):

So it can be boiled down to following one-liner.

['a','b',1].filter(item => typeof item ==='string');

This is fairly easy on processing power required:

(string1(.|\n)*string2)|(string2(.|\n)*string1)

I used this in visual studio 2013 to find all files that had both string 1 and 2 in it.

To export multiple functions you can just list them like this:

module.exports = {
   function1,
   function2,
   function3
}

And then to access them in another file:

var myFunctions = require("./lib/file.js")

And then you can call each function by calling:

myFunctions.function1
myFunctions.function2
myFunctions.function3

string path = Path.GetDirectoryName(typeof(DaoTests).Module.FullyQualifiedName);

I think what you want is to set the android:layout_weight,

http://developer.android.com/resources/tutorials/views/hello-linearlayout.html

something like this (I'm just putting text views above and below as placeholders):

  <LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1">
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="68"/>
    <Gallery 
        android:id="@+id/gallery"
        android:layout_width="fill_parent"
        android:layout_height="0dp"

        android:layout_weight="16"
    />
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="16"/>

  </LinearLayout>

Here is the code from MSDN and the link - Article Link, which you should check out for more detail.

<ComboBox Text="Is not open">
    <ComboBoxItem Name="cbi1">Item1</ComboBoxItem>
    <ComboBoxItem Name="cbi2">Item2</ComboBoxItem>
    <ComboBoxItem Name="cbi3">Item3</ComboBoxItem>
</ComboBox>

Instead of window use global

it('correct url is called', () => {
  global.open = jest.fn();
  statementService.openStatementsReport(111);
  expect(global.open).toBeCalled();
});

you could also try

const open = jest.fn()
Object.defineProperty(window, 'open', open);

 import java.util.ArrayList;
 import java.util.Iterator;


 public class javaClass {

public static void main(String args[]) {


    ArrayList<String> alstr = new ArrayList<>();
    alstr.add("irfan");
    alstr.add("yogesh");
    alstr.add("kapil");
    alstr.add("rajoria");

    for(String str : alstr) {
        System.out.println(str);
    }
    // update value here
    alstr.set(3, "Ramveer");
    System.out.println("with Iterator");
    Iterator<String>  itr = alstr.iterator();

    while (itr.hasNext()) {
        Object obj = itr.next();
        System.out.println(obj);

    }
}}

Overloading is also called static binding, so as soon as the word static is used it means a static method cannot show run-time polymorphism.

We cannot override a static method but presence of different implementations of the same static method in a super class and its sub class is valid. Its just that the derived class will hide the implementations of the base class.

For static methods, the method call depends on the type of reference and not which object is being referred, i.e. Static method belongs only to a class and not its instances , so the method call is decided at the compile time itself.

Whereas in case of method overloading static methods can be overloaded iff they have diff number or types of parameters. If two methods have the same name and the same parameter list then they cannot be defined different only by using the 'static' keyword.

>>> from datetime import datetime
>>> print(datetime.today().strftime("%H:%M %p"))
15:31 AM

Try replacing %I with %H.

How about simply (Please note, come up with a better name for the class name this is simply an example):

.centerText{
   text-align: center;
}


<div>
   <table style="width:100%">
   <tbody>
   <tr>
      <td class="centerText">Cell 1</td>
      <td>Cell 2</td>
    </tr>
    <tr>
      <td class="centerText">Cell 3</td>
      <td>Cell 4</td>
    </tr>
    </tbody>
    </table>
</div>

Example here

You can place the css in a separate file, which is recommended. In my example, I created a file called styles.css and placed my css rules in it. Then include it in the html document in the <head> section as follows:

<head>
    <link href="styles.css" rel="stylesheet" type="text/css">
</head>

The alternative, not creating a seperate css file, not recommended at all... Create <style> block in your <head> in the html document. Then just place your rules there.

<head>
 <style type="text/css">
   .centerText{
       text-align: center;
    }
 </style>
</head>

Play around this piece of code. Focus on the concept, edit where necessary so that it can

<html>
<head>
    <title> Delegate edit form</title>
</head>
<body>
    Delegate update form  </p>

Thanks to this guys I did it http://highoncoding.com/Articles/848_Creating_iPad_Dashboard_Using_UIViewController_Containment.aspx

Add UIView, connect it to header:

@property (weak, nonatomic) IBOutlet UIView *addViewToAddPlot;

In - (void)viewDidLoad do this:

ViewControllerToAdd *nonSystemsController = [[ViewControllerToAdd alloc] initWithNibName:@"ViewControllerToAdd" bundle:nil];
    nonSystemsController.view.frame = self.addViewToAddPlot.bounds;
    [self.addViewToAddPlot addSubview:nonSystemsController.view];
    [self addChildViewController:nonSystemsController];
    [nonSystemsController didMoveToParentViewController:self];

Enjoy

The other solutions seem to stray from the blessed path and I found that my scenario was covered in the Typescript documentation which I've paraphrased below:

interface AppPackageCheck<T> {
  new (packageExists: boolean): T
  checkIfPackageExists(): boolean;
}

class WebApp {
    public static checkIfPackageExists(): boolean {
        return false;
    }

    constructor(public packageExists: boolean) {}
}

class BackendApp {
    constructor(public packageExists: boolean) {}
}

function createApp<T>(type: AppPackageCheck<T>): T {
    const packageExists = type.checkIfPackageExists();
    return new type(packageExists)
}

let web = createApp(WebApp);

// compiler failure here, missing checkIfPackageExists
let backend = createApp(BackendApp); 

I see no difference between std::stream/FILE/device. Between buffering and non buffering.

Also note:

• SSD drives "tend" to slow down (lower transfer rates) as they fill up.
• SSD drives "tend" to slow down (lower transfer rates) as they get older (because of non working bits).

I am seeing the code run in 63 secondds.
Thus a transfer rate of: 260M/s (my SSD look slightly faster than yours).

64 * 1024 * 1024 * 8 /*sizeof(unsigned long long) */ * 32 /*Chunks*/

= 16G
= 16G/63 = 260M/s

I get a no increase by moving to FILE* from std::fstream.

#include <stdio.h>

using namespace std;

int main()
{
    
    FILE* stream = fopen("binary", "w");

    for(int loop=0;loop < 32;++loop)
    {
         fwrite(a, sizeof(unsigned long long), size, stream);
    }
    fclose(stream);

}

So the C++ stream are working as fast as the underlying library will allow.

But I think it is unfair comparing the OS to an application that is built on-top of the OS. The application can make no assumptions (it does not know the drives are SSD) and thus uses the file mechanisms of the OS for transfer.

While the OS does not need to make any assumptions. It can tell the types of the drives involved and use the optimal technique for transferring the data. In this case a direct memory to memory transfer. Try writing a program that copies 80G from 1 location in memory to another and see how fast that is.

Edit

I changed my code to use the lower level calls:
ie no buffering.

#include <fcntl.h>
#include <unistd.h>


const unsigned long long size = 64ULL*1024ULL*1024ULL;
unsigned long long a[size];
int main()
{
    int data = open("test", O_WRONLY | O_CREAT, 0777);
    for(int loop = 0; loop < 32; ++loop)
    {   
        write(data, a, size * sizeof(unsigned long long));
    }   
    close(data);
}

This made no diffference.

NOTE: My drive is an SSD drive if you have a normal drive you may see a difference between the two techniques above. But as I expected non buffering and buffering (when writting large chunks greater than buffer size) make no difference.

Edit 2:

Have you tried the fastest method of copying files in C++

int main()
{
    std::ifstream  input("input");
    std::ofstream  output("ouptut");

    output << input.rdbuf();
}

You can go settings, select packages and type atom-runner there if your browser can't open this link.

To run your code do Alt+R if you're using Windows in Atom.

Other way to center one line text is:

.parent{
  position: relative;
}

.child{
   position: absolute;
   top: 50%;
   line-height: 0;
}

or just

.parent{
  overflow: hidden; /* if this ins't here the parent will adopt the 50% margin of the child */
}

.child{
   margin-top: 50%;
   line-height: 0;
}

For Asp.net Core 2

ViewContext.ModelState["id"].AttemptedValue

encodeURIComponent(JSON.stringify(object_to_be_serialised))

Use jackson-bom which will have all the three jackson versions.i.e.jackson-annotations, jackson-core and jackson-databind. This will resolve the dependencies related to those versions

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

If you don't want to use float, the easiest and cleanest way to do it is by using an auto width column:

<div class="row">
  <div class="col">
    <h3 class="one">Text</h3>
  </div>
  <div class="col-auto">
    <button class="btn btn-secondary pull-right">Button</button>
  </div>
</div>

I came across this post while searching for a way to clear the entire form related to the BFCache (back/forward button cache) in Chrome.

In addition to what Sim supplied, my use case required that the details needed to be combined with Clear Form on Back Button?.

I found that the best way to do this is in allow the form to behave as it expects, and to trigger an event:

$(window).bind("pageshow", function() {
    var form = $('form'); 
    // let the browser natively reset defaults
    form[0].reset();
});

If you are not handling the input events to generate an object in JavaScript, or something else for that matter, then you are done. However, if you are listening to the events, then at least in Chrome you need to trigger a change event yourself (or whatever event you care to handle, including a custom one):

form.find(':input').not(':button,:submit,:reset,:hidden').trigger('change');

That must be added after the reset to do any good.

you should add plug in to your local setting of firefox in your user home

I'm getting OpenJDK 8 from the official Debian repositories, rather than some random PPA or non-free Oracle binary. Here's how I did it:

sudo apt-get install debian-keyring debian-archive-keyring

Make /etc/apt/sources.list.d/debian-jessie-backports.list:

deb http://httpredir.debian.org/debian/ jessie-backports main

Make /etc/apt/preferences.d/debian-jessie-backports:

Package: *
Pin: release o=Debian,a=jessie-backports
Pin-Priority: -200

Then finally do the install:

sudo apt-get update
sudo apt-get -t jessie-backports install openjdk-8-jdk

Instead of overriding the library search path at runtime with LD_LIBRARY_PATH, you could instead bake it into the binary itself with rpath. If you link with GCC adding -Wl,-rpath,<libdir> should do the trick, if you link with ld it's just -rpath <libdir>.

If you want to send a custom HTTP Header (not a SOAP Header) then you need to use the HttpWebRequest class the code would look like:

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("Authorization", token);

You cannot add HTTP headers using the visual studio generated proxy, which can be a real pain.

You can read files in raw/res using getResources().openRawResource(R.raw.myfilename).

BUT there is an IDE limitation that the file name you use can only contain lower case alphanumeric characters and dot. So file names like XYZ.txt or my_data.bin will not be listed in R.

Just add in the '0' in your select.

INSERT INTO table_name (a,b,c,d)
    SELECT
       other_table.a AS a,
       other_table.b AS b,
       other_table.c AS c,
       '0' AS d
    FROM other_table

Define "doesn't work".

const date = moment("2015-07-02"); // Thursday Feb 2015_x000D_
const dow = date.day();_x000D_
console.log(dow);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>

This prints "4", as expected.

you could keep your files untracked after

git rm -r --cached <file>

add your files with

git add -u

them push or do whatever you want.

I had the same issue, but I was running Ubuntu 12.04 through a VM. I am using a Nexus 10. I had added the usb device as a filter for the VM (using virtual box in the virtual machine's settings).

The device I had added was "samsung Nexus 10".

The problem is that once the device is in fastboot mode, it shows up as a different device: "Google, Inc Android 1.0." So doing "lsusb" in the VM showed no device connected, and obviously "fastboot devices" returned nothing until I added the "second" device as a filter for the VM as well.

Hope this helps someone.

Using == to compare two enum values works, because there is only one object for each enum constant.

On a side note, there is actually no need to use == to write null-safe code, if you write your equals() like this:

public useEnums(final SomeEnum a) {
    if (SomeEnum.SOME_ENUM_VALUE.equals(a)) {
        …
    }
    …
}

This is a best practice known as Compare Constants From The Left that you definitely should follow.

The VH unit can be used to fill the background of the viewport, aka the browser window.

Building on @Valentyn's answer a bit, here's one way to always automatically clear the cache whenever the ng-view content changes:

myApp.run(function($rootScope, $templateCache) {
   $rootScope.$on('$viewContentLoaded', function() {
      $templateCache.removeAll();
   });
});

The second parameter is selected, so use the ! to select the no value when the boolean is false.

<%= Html.RadioButton("blah", !Model.blah) %> Yes 
<%= Html.RadioButton("blah", Model.blah) %> No 

   try{

    BufferedReader br = new BufferedReader(new FileReader("textfile.txt"));
    String strLine;
    //Read File Line By Line
    while ((strLine = br.readLine()) != null)   {
      // Print the content on the console
      System.out.println (strLine);
    }
    //Close the input stream
    in.close();
    }catch (Exception e){//Catch exception if any
      System.err.println("Error: " + e.getMessage());
    }finally{
     in.close();
    }

This will read line by line,

If your no. are saperated by newline char. then in place of

 System.out.println (strLine);

You can have

try{
int i = Integer.parseInt(strLine);
}catch(NumberFormatException npe){
//do something
}  

If it is separated by spaces then

try{
    String noInStringArr[] = strLine.split(" ");
//then you can parse it to Int as above
    }catch(NumberFormatException npe){
    //do something
    }  

Hm. You have to specify window you clicked in Mouse.GetPosition(IInputElement relativeTo) Following code works well for me

protected override void OnMouseDown(MouseButtonEventArgs e)
    {
        base.OnMouseDown(e);
        Point p = e.GetPosition(this);
    }

I suspect that you need to refer to the window not from it own class but from other point of the application. In this case Application.Current.MainWindow will help you.

-(UIImage *)convertViewToImage
{
    UIGraphicsBeginImageContext(self.bounds.size);
    [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

  return image;
}

Using Javascript, you can make the two div tags the same height. The smaller div will adjust to be the same height as the tallest div tag using the code shown below:

var rightHeight = document.getElementById('right').clientHeight;
var leftHeight = document.getElementById('left').clientHeight;
if (leftHeight > rightHeight) {
document.getElementById('right').style.height=leftHeight+'px';
} else {
document.getElementById('left').style.height=rightHeight+'px';
}

With "left" and "right" being the id's of the div tags.

If you are using react's templates, where the end of your react file looks like this: export default SomeComponent you need to use the higher-order component (often referred to as an "HOC"), withRouter.

First, you'll need to import withRouter like so:

import {withRouter} from 'react-router-dom';

Next, you'll want to use withRouter. You can do this by change your component's export. It's likely you want to change from export default ComponentName to export default withRouter(ComponentName).

Then you can get the route (and other information) from props. Specifically, location, match, and history. The code to spit out the pathname would be:

console.log(this.props.location.pathname);

A good writeup with additional information is available here: https://reacttraining.com/react-router/core/guides/philosophy

First, checkout to your Branch3:

git checkout Branch3

Then merge the Branch1:

git merge Branch1

And if you want the updated commits of Branch1 on Branch2, you are probaly looking for git rebase

git checkout Branch2
git rebase Branch1

This will update your Branch2 with the latest updates of Branch1.

This is the best one I've found.

Here's my attempt at doing this:

Step 1: Create a style named SearchViewStyle

<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the search icon -->
    <item name="searchIcon">@drawable/search</item>
    <!-- Gets rid of the "underline" in the text -->
    <item name="queryBackground">@null</item>
    <!-- Gets rid of the search icon when the SearchView is expanded -->
    <item name="searchHintIcon">@null</item>
    <!-- The hint text that appears when the user has not typed anything -->
    <item name="queryHint">@string/search_hint</item>
</style>

Step 2: Create a layout named simple_search_view_item.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView
    android:layout_gravity="end"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    style="@style/SearchViewStyle"
    xmlns:android="http://schemas.android.com/apk/res/android" />  

Step 3: Create a menu item for this search view

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        app:actionLayout="@layout/simple_search_view_item"
        android:title="@string/search"
        android:icon="@drawable/search"
        app:showAsAction="always" />
</menu>  

Step 4: Inflate the menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_searchable_activity, menu);
    return true;
}  

Result:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar. If someone could help me do that then that'd be golden.

byte[] data; using(Stream inputStream=file.InputStream) { MemoryStream memoryStream = inputStream as MemoryStream; if (memoryStream == null) { memoryStream = new MemoryStream(); inputStream.CopyTo(memoryStream); } data = memoryStream.ToArray(); }

It is not an import problem. You simply call .dropDuplicates() on a wrong object. While class of sqlContext.createDataFrame(rdd1, ...) is pyspark.sql.dataframe.DataFrame, after you apply .collect() it is a plain Python list, and lists don't provide dropDuplicates method. What you want is something like this:

 (df1 = sqlContext
     .createDataFrame(rdd1, ['column1', 'column2', 'column3', 'column4'])
     .dropDuplicates())

 df1.collect()

You can do the following :-

$(document).ready(function(){
    $("#id").trigger("click");
});

Deleting the package-lock.json did it for me. I'd suggest you not push package-lock.json to your repo as I wasted hours trying to npm install with the package-lock.json in the folder which gave me helluva errors.

There's an "edit configurations" item on the Run menu, and on the pull-down to the left of the two green "run" and "debug" arrows on the toolbar. In that panel, you create a configuration with the "+" button in the top left, and then you can choose the Class containing main(), add VM parameters and command-line args, specify the working directory and any environment variables.

There are other options there as well: code coverage, logging, build, JRE, etc.

If you have the option of giving a fixed width to the table cells (and a fixed height to the header), you can used the position: fixed option:

http://jsfiddle.net/thundercracker/ZxPeh/23/

You would just have to stick it in an iframe. You could also have horizontal scrolling by giving the iframe a scrollbar (I think).

Edit 2015

If you can live with a pre-defining the width of your table cells (by percentage), then here's a bit more elegant (CSS-only) solution:

http://jsfiddle.net/7UBMD/77/

private void button1_Click(object sender, EventArgs e)
    {
        String query = "INSERT INTO product (productid, productname,productdesc,productqty) VALUES (@txtitemid,@txtitemname,@txtitemdesc,@txtitemqty)";
        try
        {
            using (SqlCommand command = new SqlCommand(query, con))
            {

                command.Parameters.AddWithValue("@txtitemid", txtitemid.Text);
                command.Parameters.AddWithValue("@txtitemname", txtitemname.Text);
                command.Parameters.AddWithValue("@txtitemdesc", txtitemdesc.Text);
                command.Parameters.AddWithValue("@txtitemqty", txtitemqty.Text);


                con.Open();
                int result = command.ExecuteNonQuery();

                // Check Error
                if (result < 0)
                    MessageBox.Show("Error");

                MessageBox.Show("Record...!", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
                con.Close();
                loader();
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
            con.Close();
        }
    }

it simple way in xml:

android:maxLength="4"

if u require to set 4 character in xml edit-text so,use this

<EditText
    android:id="@+id/edtUserCode"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:maxLength="4"
    android:hint="Enter user code" />

Ran into the same thing trying to install brew's python3 under Mac OS! The issue here is that in Mac OS, homebrew puts the "real" python a whole layer deeper than you think. You would think from the homebrew output that

$ echo $PYTHONHOME
/usr/local/Cellar/python3/3.6.2/
$ echo $PYTHONPATH
/usr/local/Cellar/python3/3.6.2/bin

would be correct, but invoking $PYTHONPATH/python3 immediately crashes with the abort 6 "can't find encodings." This is because although that $PYTHONHOME looks like a complete installation, having a bin, lib etc, it is NOT the actual Python, which is in a Mac OS "Framework". Do this:

PYTHONHOME=/usr/local/Cellar/python3/3.x.y/Frameworks/Python.framework/Versions/3.x
PYTHONPATH=$PYTHONHOME/bin

(substituting version numbers as appropriate) and it will work fine.

Just to elaborate on the etymology of the command name rev-parse, Git consistently uses the term rev in plumbing commands as short for "revision" and generally meaning the 40-character SHA1 hash for a commit. The command rev-list for example prints a list of 40-char commit hashes for a branch or whatever.

In this case the name might be expanded to parse-a-commitish-to-a-full-SHA1-hash. While the command has the several ancillary functions mentioned in Tuxdude's answer, its namesake appears to be the use case of transforming a user-friendly reference like a branch name or abbreviated hash into the unambiguous 40-character SHA1 hash most useful for many programming/plumbing purposes.

I know I was thinking it was "reverse-parse" something for quite a while before I figured it out and had the same trouble making sense of the terms "massaging" and "manipulation" :)

Anyway, I find this "parse-to-a-revision" notion a satisfying way to think of it, and a reliable concept for bringing this command to mind when I need that sort of thing. Frequently in scripting Git you take a user-friendly commit reference as user input and generally want to get it resolved to a validated and unambiguous working reference as soon after receiving it as possible. Otherwise input translation and validation tends to proliferate through the script.

The JavaScript native .some() method does exactly what you're looking for:

function isBiggerThan10(element, index, array) {
  return element > 10;
}

[2, 5, 8, 1, 4].some(isBiggerThan10);  // false
[12, 5, 8, 1, 4].some(isBiggerThan10); // true

.text-left {
  text-align: left;
}

.text-right {
  text-align: right;
}

.text-center {
  text-align: center;
}

bootstrap has added three css classes for text align.

android split string by comma

String data = "1,Diego Maradona,Footballer,Argentina";
String[] items = data.split(",");
for (String item : items)

For count of different commits from HEAD to origin/master:

git remote update
git rev-list HEAD..origin/master --count

To get current HEAD commit hash id:

git rev-parse HEAD

To get remote origin/master commit hash id:

git rev-parse origin/master

break; is what you need to break out of any looping statement like for, while or do-while.

In your case, its going to be like this:-

for(int x = 10; x < 20; x++) {
         // The below condition can be present before or after your sysouts, depending on your needs.
         if(x == 15){
             break; // A unlabeled break is enough. You don't need a labeled break here.
         }
         System.out.print("value of x : " + x );
         System.out.print("\n");
}

If the TextFX menu does not exist, you need to download & install the plugin. Plugins->Plugin Manager->Show Plugin Manager and then check the plugin TextFX Characters. Click 'install,' restart Notepad++.

In version Notepad++ v6.1.3, I resolve with: Plugin Manager->Show Plugin Manager** and then check the plugin "Indent By Fold"

I've found that there will be a new version of npm 5.7.1 with the new command npm ci, that will install from package-lock.json only

The new npm ci command installs from your lock-file ONLY. If your package.json and your lock-file are out of sync then it will report an error.

It works by throwing away your node_modules and recreating it from scratch.

Beyond guaranteeing you that you'll only get what is in your lock-file it's also much faster (2x-10x!) than npm install when you don't start with a node_modules.

As you may take from the name, we expect it to be a big boon to continuous integration environments. We also expect that folks who do production deploys from git tags will see major gains.

Use directions service of Google Maps API v3. It's basically the same as directions API, but nicely packed in Google Maps API which also provides convenient way to easily render the route on the map.

Information and examples about rendering the directions route on the map can be found in rendering directions section of Google Maps API v3 documentation.

And if you'd like to extract the differences between the two strings, you can use String::Diff.

On secure networks setting your network to bridge might not work. Administrators could only allow one mac address per port or even worse block the port should the switches detect multiple macs on one port.

The best solution in my opinion is to set up additional network interfaces to handle additional services you would like to run on your machines. So I have a bridge interface to allow for bridging when I take my laptop home and can SSH into it from other devices on my network as well as a host only adapter when I would like to SSH into my VM from my laptop when I am connected to the eduroam wifi network on campus.

Basically, replace replaces a character with another and '' is not a character. What you're looking for is erase.

See this question which answers the same problem. In your case:

#include <algorithm>
str.erase(std::remove(str.begin(), str.end(), 'a'), str.end());

Or use boost if that's an option for you, like:

#include <boost/algorithm/string.hpp>
boost::erase_all(str, "a");

All of this is well-documented on reference websites. But if you didn't know of these functions, you could easily do this kind of things by hand:

std::string output;
output.reserve(str.size()); // optional, avoids buffer reallocations in the loop
for(size_t i = 0; i < str.size(); ++i)
  if(str[i] != 'a') output += str[i];

Yes to the first question and no to the second question; it's a virtual machine. Your problems are probably related to unspecified changes in library implementation between versions. Although it could be, say, a race condition.

There are some hoops the VM has to go through. Notably references are treated in class files as if they took the same space as ints on the stack. double and long take up two reference slots. For instance fields, there's some rearrangement the VM usually goes through anyway. This is all done (relatively) transparently.

Also some 64-bit JVMs use "compressed oops". Because data is aligned to around every 8 or 16 bytes, three or four bits of the address are useless (although a "mark" bit may be stolen for some algorithms). This allows 32-bit address data (therefore using half as much bandwidth, and therefore faster) to use heap sizes of 35- or 36-bits on a 64-bit platform.

The problem could be in Flex's SOAP encoder. Try extending the SOAP encoder in your Flex application and debug the program to see how the null value is handled.

My guess is, it's passed as NaN (Not a Number). This will mess up the SOAP message unmarshalling process sometime (most notably in the JBoss 5 server...). I remember extending the SOAP encoder and performing an explicit check on how NaN is handled.

I've done it finaly check it and if there is a better way tell me guys

This seems like an old thread, but I'll add my experience here. I tried to install a cert as well and got that error. I then opened the cer file with a txt editor, and noticed that there is an extra space (character) at the end of each line. Removing those lines allowed me to import the cert.

Hope this is worth something to someone else.

You can push your local branch to a new remote branch like so:

git push origin master:test

(Assuming origin is your remote, master is your local branch name and test is the name of the new remote branch, you wish to create.)

If at the same time you want to set up your local branch to track the newly created remote branch, you can do so with -u (on newer versions of Git) or --set-upstream, so:

git push -u origin master:test

or

git push --set-upstream origin master:test

...will create a new remote branch, named test, in remote repository origin, based on your local master, and setup your local master to track it.

In Java side, the date is usually represented by the (poorly designed, but that aside) java.util.Date. It is basically backed by the Epoch time in flavor of a long, also known as a timestamp. It contains information about both the date and time parts. In Java, the precision is in milliseconds.

In SQL side, there are several standard date and time types, DATE, TIME and TIMESTAMP (at some DB's also called DATETIME), which are represented in JDBC as java.sql.Date, java.sql.Time and java.sql.Timestamp, all subclasses of java.util.Date. The precision is DB dependent, often in milliseconds like Java, but it can also be in seconds.

In contrary to java.util.Date, the java.sql.Date contains only information about the date part (year, month, day). The Time contains only information about the time part (hours, minutes, seconds) and the Timestamp contains information about the both parts, like as java.util.Date does.

The normal practice to store a timestamp in the DB (thus, java.util.Date in Java side and java.sql.Timestamp in JDBC side) is to use PreparedStatement#setTimestamp().

java.util.Date date = getItSomehow();
Timestamp timestamp = new Timestamp(date.getTime());
preparedStatement = connection.prepareStatement("SELECT * FROM tbl WHERE ts > ?");
preparedStatement.setTimestamp(1, timestamp);

The normal practice to obtain a timestamp from the DB is to use ResultSet#getTimestamp().

Timestamp timestamp = resultSet.getTimestamp("ts");
java.util.Date date = timestamp; // You can just upcast.

function removeElements(){
  $('#models').html('');
}

You can do just:

var regex = /^[1-9]\d{0,2}$/g
regex.test('2') // outputs true

"tail" is command to display the last part of a file, using proper available switches helps us to get more specific output. the most used switch for me is -n and -f

SYNOPSIS

tail [-F | -f | -r] [-q] [-b number | -c number | -n number] [file ...]

Here

-n number : The location is number lines.

-f : The -f option causes tail to not stop when end of file is reached, but rather to wait for additional data to be appended to the input. The -f option is ignored if the standard input is a pipe, but not if it is a FIFO.

Retrieve last 100 lines logs

To get last static 100 lines  
     tail -n 100 <file path>

To get real time last 100 lines
     tail -f -n 100 <file path>

Thanks to this answer: A perfect tool to run a background process would be Symfony Process Component, which is based on proc_* functions, but it's much easier to use. See its documentation for more information.

If you should need to replace the handle with something else entirely, rather than just restyling it:

You can specify custom handle elements by creating and appending the elements and adding the ui-slider-handle class before initialization.

Working Example

$('.slider').append('<div class="my-handle ui-slider-handle"><svg height="18" width="14"><path d="M13,9 5,1 A 10,10 0, 0, 0, 5,17z"/></svg></div>');_x000D_
_x000D_
$('.slider').slider({_x000D_
  range: "min",_x000D_
  value: 10_x000D_
});

.slider .ui-state-default {_x000D_
  background: none;_x000D_
}_x000D_
.slider.ui-slider .ui-slider-handle {_x000D_
  width: 14px;_x000D_
  height: 18px;_x000D_
  margin-left: -5px;_x000D_
  top: -4px;_x000D_
  border: none;_x000D_
  background: none;_x000D_
}_x000D_
.slider {_x000D_

}

I had to set the value in '' and ""

spring:
   jpa:
     properties:
       hibernate:
          default_schema: '"schema"'

Try doing it this way, it worked for me:

$this->validate($request, [
'name' => 'required|min:3|max:50',
'email' => 'email',
'vat_number' => 'max:13',
'password' => 'min:6|required_with:password_confirmation|same:password_confirmation',
'password_confirmation' => 'min:6'
]);`

Seems like the rule always has the validation on the first input among the pair...

I think this post by Jeff Attwood addresses your question perfectly. It takes you through the differences between newlines on Dos, Mac and Unix, and then explains the history of CR (Carriage return) and LF (Line feed).

After spending a whole day and a half trying to work through a similar problem I found it had to do with IIS.

My Web API project was set up as follows:

// WebApiConfig.cs
public static void Register(HttpConfiguration config)
{
    var cors = new EnableCorsAttribute("*", "*", "*");
    config.EnableCors(cors);
    //...
}

I did not have CORS specific config options in the web.config > system.webServer node like I have seen in so many posts

No CORS specific code in the global.asax or in the controller as a decorator

The problem was the app pool settings.

The managed pipeline mode was set to classic (changed it to integrated) and the Identity was set to Network Service (changed it to ApplicationPoolIdentity)

Changing those settings (and refreshing the app pool) fixed it for me.

Python doesn't support ++, but you can do:

number += 1

git clone <Repo> <DestinationDirectory>

Clone the repository located at Repo into the folder called DestinationDirectory on the local machine.

Assuming the column is set to support NULL as a value:

UPDATE YOUR_TABLE
   SET column = NULL

Be aware of the database NULL handling - by default in SQL Server, NULL is an INT. So if the column is a different data type you need to CAST/CONVERT NULL to the proper data type:

UPDATE YOUR_TABLE
   SET column = CAST(NULL AS DATETIME)

...assuming column is a DATETIME data type in the example above.

A simple way would be to use pandas. I adapted an example from the plotting documentation:

In [1]: import pandas as pd, numpy as np

In [2]: df = pd.DataFrame(np.random.rand(12,2), columns=['Apples', 'Oranges'] )

In [3]: df['Categories'] = pd.Series(list('AAAABBBBCCCC'))

In [4]: pd.options.display.mpl_style = 'default'

In [5]: df.boxplot(by='Categories')
Out[5]: 
array([<matplotlib.axes.AxesSubplot object at 0x51a5190>,
       <matplotlib.axes.AxesSubplot object at 0x53fddd0>], dtype=object)

AttributeError("'str' object has no attribute 'read'",)

This means exactly what it says: something tried to find a .read attribute on the object that you gave it, and you gave it an object of type str (i.e., you gave it a string).

The error occurred here:

json.load (jsonofabitch)['data']['children']

Well, you aren't looking for read anywhere, so it must happen in the json.load function that you called (as indicated by the full traceback). That is because json.load is trying to .read the thing that you gave it, but you gave it jsonofabitch, which currently names a string (which you created by calling .read on the response).

Solution: don't call .read yourself; the function will do this, and is expecting you to give it the response directly so that it can do so.

You could also have figured this out by reading the built-in Python documentation for the function (try help(json.load), or for the entire module (try help(json)), or by checking the documentation for those functions on http://docs.python.org .

SELECT * FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

Update : for better performance and faster query its good to add e1 before *

SELECT e1.* FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

You have a stale version of the package with commands that no longer accept zookeeper but rather bootstrap-server as the connection. Confluent will then connect with Zookeeper internally.

You can also try: (I tried this and it worked for me)

SELECT ISNULL((SELECT SUM(columnA) FROM my_table WHERE columnB = 1),0)) INTO res;

data attributes are commonly used for a variety of interactions. Typically via javascript. They do not affect anything regarding site behavior and stand as a convenient method to pass data for whatever purpose needed. Here is an article that may clear things up:

http://ejohn.org/blog/html-5-data-attributes/

You can create a data attribute by prefixing data- to any standard attribute safe string (alphanumeric with no spaces or special characters). For example, data-id or in this case data-reactid

When the using() for your StreamReader is ending, it's disposing the object and closing the stream, which your StreamWriter is still trying to use.

In batch you could do it like this:

@echo off

setlocal EnableDelayedExpansion

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do (
  set "var=%%sxyz"
  svn co "!var!"
)

If you don't need the variable !var! elsewhere in the loop, you could simplify that to

@echo off

setlocal

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do svn co "%%sxyz"

However, like C.B. I'd prefer PowerShell if at all possible:

$string_list = 'str1', 'str2', 'str3', ... 'str10'

$string_list | ForEach-Object {
  $var = "${_}xyz"   # alternatively: $var = $_ + 'xyz'
  svn co $var
}

Again, this could be simplified if you don't need $var elsewhere in the loop:

$string_list = 'str1', 'str2', 'str3', ... 'str10'
$string_list | ForEach-Object { svn co "${_}xyz" }

Consider normalizing to E.164 format. For full international support, you'd need a VARCHAR of 15 digits.

See Twilio's recommendation for more information on localization of phone numbers.

Use a lambda to pass the entry data to the command function if you have more actions to carry out, like this (I've tried to make it generic, so just adapt):

event1 = Entry(master)
button1 = Button(master, text="OK", command=lambda: test_event(event1.get()))

def test_event(event_text):
    if not event_text:
        print("Nothing entered")
    else:
        print(str(event_text))
        #  do stuff

This will pass the information in the event to the button function. There may be more Pythonesque ways of writing this, but it works for me.

Alternatively you can just create a tunnel to the server:

ssh -i <your_key> <user@server-instance> -L 8888:127.0.0.1:8888

Then just open 127.0.0.1:8888 in your browser.

You also omit the -i <your_key> if you don't have an identity_file.

<TextView
    android:id="@+id/textView3"
    android:layout_width="match_parent"
    android:layout_height="2dp"
    android:background="#72cdf4"
    android:text=" aa" />

Just Add this TextView below the text where you want to add the border

import numpy as np    
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))

Below, hist indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.

print(hist)
# array([0, 2, 4, 1])   

bin_edges indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ..., bin #3 is [3,4).

print (bin_edges)
# array([0, 1, 2, 3, 4]))  

Play with the above code, change the input to np.histogram and see how it works.

But a picture is worth a thousand words:

import matplotlib.pyplot as plt
plt.bar(bin_edges[:-1], hist, width = 1)
plt.xlim(min(bin_edges), max(bin_edges))
plt.show()   

Seems like getTime is not function on above answer.

This has happened to me. My issue was caused when I didn't mount Docker file system correctly, so I configured the Disk Image Location and re-bind File sharing mount, and this now worked correctly. For reference, I use Docker Desktop in Windows.

Here is a multi-IP address version of jhurliman's answer:

function getIPAddresses() {

    var ipAddresses = [];

    var interfaces = require('os').networkInterfaces();
    for (var devName in interfaces) {
        var iface = interfaces[devName];
        for (var i = 0; i < iface.length; i++) {
            var alias = iface[i];
            if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal) {
                ipAddresses.push(alias.address);
            }
        }
    }
    return ipAddresses;
}

scale(..) works a bit differently. You can use bufferedImage.getScaledInstance(..)

Strings are special in Java - they're immutable, and string constants are automatically turned into String objects.

There's no way for your SomeStringClass cis = "value" example to apply to any other class.

Nor can you extend String, because it's declared as final, meaning no sub-classing is allowed.

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

I know, I am already late but let me add my simple and working answer here

const query = {} //your query here
const update = {} //your update in json here
const option = {new: true} //will return updated document

const user = await User.findOneAndUpdate(query , update, option)

On a Mac use command+shift+\.

Source: a comment on this answer: https://stackoverflow.com/a/37877082/3345085. Tested in Visual Studio Code version 1.10.2.

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

Here is my some code

$dir          = '/Images';
$ImagesA = Get_ImagesToFolder($dir);
print_r($ImagesA);

function Get_ImagesToFolder($dir){
    $ImagesArray = [];
    $file_display = [ 'jpg', 'jpeg', 'png', 'gif' ];

    if (file_exists($dir) == false) {
        return ["Directory \'', $dir, '\' not found!"];
    } 
    else {
        $dir_contents = scandir($dir);
        foreach ($dir_contents as $file) {
            $file_type = pathinfo($file, PATHINFO_EXTENSION);
            if (in_array($file_type, $file_display) == true) {
                $ImagesArray[] = $file;
            }
        }
        return $ImagesArray;
    }
}

Another possibility is to set the app:actionViewClass attribute in your menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">
  <item
     android:id="@+id/get_item"
     android:orderInCategory="1"
     android:text="Get"
     app:showAsAction="always" 
     app:actionViewClass="android.support.v7.widget.AppCompatButton"/>
</menu>

In your code you can access this button after the menu was inflated:

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater menuInflater = getMenuInflater();
    menuInflater.inflate(R.menu.sample, menu);

    MenuItem getItem = menu.findItem(R.id.get_item);
    if (getItem != null) {
        AppCompatButton button = (AppCompatButton) getItem.getActionView();
        //Set a ClickListener, the text, 
        //the background color or something like that
    }

    return super.onCreateOptionsMenu(menu);
}

You can make an additional column to store the uniqueness, then sum that up in your pivot table.

What I mean is, cell C1 should always be 1. Cell C2 should contain the formula =IF(COUNTIF($A$1:$A1,$A2)*COUNTIF($B$1:$B1,$B2)>0,0,1). Copy this formula down so cell C3 would contain =IF(COUNTIF($A$1:$A2,$A3)*COUNTIF($B$1:$B2,$B3)>0,0,1) and so on.

If you have a header cell, you'll want to move these all down a row and your C3 formula should be =IF(COUNTIF($A$2:$A2,$A3)*COUNTIF($B$2:$B2,$B3)>0,0,1).

...you may also want to check for cross site scripting issues...if your html pages comes from a different domain/port combi then your rest service, your browser may block the call.

Typically, right mouse->inspect on your html page. Then look in the error console for errors like

Access to XMLHttpRequest at '...:8080' from origin '...:8383' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Here I've collected the "good ones" from this page and put them into a simple test pattern for you to evaluate on your own.

For newbies, the console.log is a built in function (available in all modern browsers) that lets you output results to the JavaScript console (dig around, you'll find it) rather than having to output to your HTML page.

    console.log( "test " + i + ":    " + tests[i] + "    \t   " + isNumeric(tests[i]) );
}

I'm using

buildTypes.each {
    it.buildConfigField 'String', 'GoogleMapsApiKey', "\"$System.env.GoogleMapsApiKey\""
}

Its based on Dennis's answer but grabs its from an environment variable.

Lets start with 3. That wouldnt work. public getMyProperty() has no return typ.

And number 1 and 2 are actually same things. 2 is what number 1 becomes after compilation.

So 1 and 2 are same things. with two you can have some validation or caching in your model.

other than that they become same.

I threw this together so that you could do some querying on the results

Simply add it to your current code, then call (new Date()).getWeek()

<script>
    Date.prototype.getWeek = function() {
        var onejan = new Date(this.getFullYear(), 0, 1);
        return Math.ceil((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7);
    }

    var weekNumber = (new Date()).getWeek();

    var dayNames = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
    var now = new Date();
    document.write(dayNames[now.getDay()] + " (" + weekNumber + ").");
</script>

You also have to make sure that your encoding filter (org.springframework.web.filter.CharacterEncodingFilter) in your web.xml is mapped before the multipart filter (org.springframework.web.multipart.support.MultipartFilter).

Your .vimrc file goes in your $HOME directory. In *nix, cd ~; vim .vimrc. The commands in the .vimrc are the same as you type in ex-mode in vim, only without the leading colon, so colo evening would suffice. Comments in the .vimrc are indicated with a leading double-quote.

To see an example vimrc, open $VIMRUNTIME/vimrc_example.vim from within vim

:e $VIMRUNTIME/vimrc_example.vim

Use something like this:

class Tree < T > : Dictionary < T, IList< Tree < T > > >

It's ugly, but I think it will give you what you want. Too bad KeyValuePair is sealed.

As of 2019...

...the correct answer is to use async/await with the native fs promises module included in node. Upgrade to Node.js 10 or 11 (already supported by major cloud providers) and do this:

const fs = require('fs').promises;

// This must run inside a function marked `async`:
const file = await fs.readFile('filename.txt', 'utf8');
await fs.writeFile('filename.txt', 'test');

Do not use third-party packages and do not write your own wrappers, that's not necessary anymore.

No longer experimental

Before Node 11.14.0, you would still get a warning that this feature is experimental, but it works just fine and it's the way to go in the future. Since 11.14.0, the feature is no longer experimental and is production-ready.

What if I prefer import instead of require?

It works, too - but only in Node.js versions where this feature is not marked as experimental.

import { promises as fs } from 'fs';

(async () => {
    await fs.writeFile('./test.txt', 'test', 'utf8');
})();

hg strip is what you are looking for. It's analogous of git reset if you familiar with git.

Use console:

1. You need to know the revision number. hg log -l 10. This command shows the last 10 commits. Find commit you are looking for. You need 4 digit number from changeset line changeset: 5888:ba6205914681

2. Then hg strip -r 5888 --keep. This removes the record of the commit but keeps all files modified and then you could recommit them. (if you want to delete files to just remove --keep hg strip -r 5888

Just use valueOf() method. If the value doesn't exist, it throws IllegalArgumentException and you can catch it like that:

      boolean isSettingCodeValid = true;

       try {
            SettingCode.valueOf(settingCode.toUpperCase());
        } catch (IllegalArgumentException e) {
            // throw custom exception or change the isSettingCodeValid value
            isSettingCodeValid = false;
        }

I also received this error when I named one of my component inputs 'formControl'. Probably it's reserved for something else. If you want to pass FormControl object between components, use it like that:

@Input() control: FormControl;

not like this:

@Input() formControl: FormControl;

Weird - but working :)

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')

After= dependency is only effective when service including After= and service included by After= are both scheduled to start as part of your boot up.

Ex:

a.service
[Unit]
After=b.service

This way, if both a.service and b.service are enabled, then systemd will order b.service after a.service.

If I am not misunderstanding, what you are asking is how to start b.service when a.service starts even though b.service is not enabled.

The directive for this is Wants= or Requires= under [Unit].

website.service
[Unit]
Wants=mongodb.service
After=mongodb.service

The difference between Wants= and Requires= is that with Requires=, a failure to start b.service will cause the startup of a.service to fail, whereas with Wants=, a.service will start even if b.service fails. This is explained in detail on the man page of .unit.

The MaxAge of -1 signals that you want the cookie to persist for the duration of the session. You want to set MaxAge to 0 instead.

From the API documentation:

A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

About efficient method. You can use CursorLoader. For example I included my action. And you must implement ContentProvider for your data base. https://developer.android.com/reference/android/content/ContentProvider.html

If you implement this, you will call you data base very efficient.

public class LoadEntitiesActionImp implements LoaderManager.LoaderCallbacks<Cursor> {

   public interface OnLoadEntities {
       void onSuccessLoadEntities(List<Entities> entitiesList);
   }

    private OnLoadEntities onLoadEntities;

    private final Context context;

    private final LoaderManager loaderManager;

    public LoadEntitiesActionImp(Context context, LoaderManager loaderManager) {
        this.context = context;
        this.loaderManager = loaderManager;
    }

    public void setCallback(OnLoadEntities onLoadEntities) {
        this.onLoadEntities = onLoadEntities;
    }

    public void loadEntities() {
        loaderManager.initLoader(LOADER_ID, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle args) {
        return new CursorLoader(context, YOUR_URI, null, YOUR_SELECTION, YOUR_ARGUMENTS_FOR_SELECTION, YOUR_SORT_ORDER);
    }

    @Override
    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    }

    @Override
    public void onLoaderReset(Loader<Cursor> loader) {
    }

document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';

Using Guidelines you can change the positioning to be percentage based

<android.support.constraint.Guideline
android:id="@+id/guideline"
android:layout_width="1dp"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5"/>

You can also use this way

android:layout_width="0dp"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent="0.4"

To copy conditional formatting from google spreadsheet (doc1) to another (doc2) you need to do the following:

1. Go to the bottom of doc1 and right-click on the sheet name.
2. Select Copy to
3. Select doc2 from the options you have (note: doc2 must be on your google drive as well)
4. Go to doc2 and open the newly "pasted" sheet at the bottom (it should be the far-right one)
5. Select the cell with the formatting you want to use and copy it.
6. Go to the sheet in doc2 you would like to modify.
7. Select the cell you want your formatting to go to.
8. Right click and choose paste special and then paste conditional formatting only
9. Delete the pasted sheet if you don't want it there. Done.

Here is a great answer to that:

SET sql_mode='PIPES_AS_CONCAT';

Find more here: https://stackoverflow.com/a/24777235/4120319

Here's the full SQL:

SET sql_mode='PIPES_AS_CONCAT';

SELECT * FROM tableOne 
LEFT JOIN tableTwo
ON tableTwo.query = 'category_id=' || tableOne.category_id;

mySelect.value = myValue;

Where mySelect is your selection box, and myValue is the value you want to change it to.

Using Newtonsoft.Json: In your Global.asax Application_Start method add this line:

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

Either use the style attribute to add CSS inline on your divs, e.g.:

<div style="color:red"> ... </div>

... or create your own style sheet and reference it after the existing stylesheet then your style sheet should take precedence.

... or add a <style> element in the <head> of your HTML with the CSS you need, this will take precedence over an external style sheet.

You can also add !important after your style values to override other styles on the same element.

Update

Use one of my suggestions above and target the span of class style21, rather than the containing div. The style you are applying on the containing div will not be inherited by the span as it's color is set in the style sheet.

VLC should be able to do this.

You can use the following command to access with your ip.

ng serve --host 0.0.0.0 --disable-host-check

If you are using npm and want to avoid running the command every time, we can add the following line to the package.json file in the scripts section.

"scripts": {
    ...
    "start": "ng serve --host 0.0.0.0 --disable-host-check"
    ...
}

Then you can run you app using the below command to be accessed from the other system in the same network.

npm start

You can redirect to a new URL in different ways.

1. You can use $window which will also refresh the page
2. You can "stay inside" the single page app and use $location in which case you can choose between $location.path(YOUR_URL); or $location.url(YOUR_URL);. So the basic difference between the 2 methods is that $location.url() also affects get parameters whilst $location.path() does not.

I would recommend reading the docs on $location and $window so you get a better grasp on the differences between them.

Better

if ! wget -q --spider --tries=10 --timeout=20 google.com
then
  echo 'Sorry you are Offline'
  exit 1
fi

You can use also ShareCompat class from support library.

ShareCompat.IntentBuilder.from(activity)
    .setType("text/plain")
    .setChooserTitle("Chooser title")
    .setText("http://play.google.com/store/apps/details?id=" + activity.getPackageName())
    .startChooser();

Reading a file in and by itself takes some time, garbage collecting the result is another problem as you read the whole file just to count the newline character(s),

At some point, someone is going to have to read the characters in the file, regardless if this the framework or if it is your code. This means you have to open the file and read it into memory if the file is large this is going to potentially be a problem as the memory needs to be garbage collected.

Nima Ara made a nice analysis that you might take into consideration

Here is the solution proposed, as it reads 4 characters at a time, counts the line feed character and re-uses the same memory address again for the next character comparison.

private const char CR = '\r';  
private const char LF = '\n';  
private const char NULL = (char)0;

public static long CountLinesMaybe(Stream stream)  
{
    Ensure.NotNull(stream, nameof(stream));

    var lineCount = 0L;

    var byteBuffer = new byte[1024 * 1024];
    const int BytesAtTheTime = 4;
    var detectedEOL = NULL;
    var currentChar = NULL;

    int bytesRead;
    while ((bytesRead = stream.Read(byteBuffer, 0, byteBuffer.Length)) > 0)
    {
        var i = 0;
        for (; i <= bytesRead - BytesAtTheTime; i += BytesAtTheTime)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 1];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 2];
                if (currentChar == detectedEOL) { lineCount++; }

                currentChar = (char)byteBuffer[i + 3];
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
                i -= BytesAtTheTime - 1;
            }
        }

        for (; i < bytesRead; i++)
        {
            currentChar = (char)byteBuffer[i];

            if (detectedEOL != NULL)
            {
                if (currentChar == detectedEOL) { lineCount++; }
            }
            else
            {
                if (currentChar == LF || currentChar == CR)
                {
                    detectedEOL = currentChar;
                    lineCount++;
                }
            }
        }
    }

    if (currentChar != LF && currentChar != CR && currentChar != NULL)
    {
        lineCount++;
    }
    return lineCount;
}

Above you can see that a line is read one character at a time as well by the underlying framework as you need to read all characters to see the line feed.

If you profile it as done bay Nima you would see that this is a rather fast and efficient way of doing this.

In Unix systems the end of a line is represented with a line feed (LF). In windows a line is represented with a carriage return (CR) and a line feed (LF) thus (CRLF). when you get code from git that was uploaded from a unix system they will only have an LF.

If you are a single developer working on a windows machine, and you don't care that git automatically replaces LFs to CRLFs, you can turn this warning off by typing the following in the git command line

git config core.autocrlf true

If you want to make an intelligent decision how git should handle this, read the documentation

Here is a snippet

Formatting and Whitespace

Formatting and whitespace issues are some of the more frustrating and subtle problems that many developers encounter when collaborating, especially cross-platform. It’s very easy for patches or other collaborated work to introduce subtle whitespace changes because editors silently introduce them, and if your files ever touch a Windows system, their line endings might be replaced. Git has a few configuration options to help with these issues.

core.autocrlf

If you’re programming on Windows and working with people who are not (or vice-versa), you’ll probably run into line-ending issues at some point. This is because Windows uses both a carriage-return character and a linefeed character for newlines in its files, whereas Mac and Linux systems use only the linefeed character. This is a subtle but incredibly annoying fact of cross-platform work; many editors on Windows silently replace existing LF-style line endings with CRLF, or insert both line-ending characters when the user hits the enter key.

Git can handle this by auto-converting CRLF line endings into LF when you add a file to the index, and vice versa when it checks out code onto your filesystem. You can turn on this functionality with the core.autocrlf setting. If you’re on a Windows machine, set it to true – this converts LF endings into CRLF when you check out code:

$ git config --global core.autocrlf true

If you’re on a Linux or Mac system that uses LF line endings, then you don’t want Git to automatically convert them when you check out files; however, if a file with CRLF endings accidentally gets introduced, then you may want Git to fix it. You can tell Git to convert CRLF to LF on commit but not the other way around by setting core.autocrlf to input:

$ git config --global core.autocrlf input

This setup should leave you with CRLF endings in Windows checkouts, but LF endings on Mac and Linux systems and in the repository.

If you’re a Windows programmer doing a Windows-only project, then you can turn off this functionality, recording the carriage returns in the repository by setting the config value to false:

$ git config --global core.autocrlf false

In android studio, You can use bellow process to create & Read QR Code &image look like bellw

1. Create a android studio empty project

2. Add library in app.gradle

   compile 'com.google.zxing:core:3.2.1'
   compile 'com.journeyapps:zxing-android-embedded:3.2.0@aar'
   

3. In activity.main xml use bellow..

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.enamul.qrcode.MainActivity">
   
   <LinearLayout
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:layout_margin="20dp"
     android:orientation="vertical">
   
   
   <EditText
       android:id="@+id/editText"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"

       android:hint="Enter Text Here" />
   
   <Button
       android:id="@+id/button"
       android:layout_width="fill_parent"
       android:layout_height="50dp"
       android:layout_below="@+id/editText"
       android:text="Click Here TO generate qr code"
       android:textAllCaps="false"
       android:textSize="16sp" />
   
   
   <Button
       android:id="@+id/btnScan"
       android:layout_width="fill_parent"
       android:layout_height="50dp"
       android:layout_below="@+id/editText"
       android:text="Scan Your QR Code"
       android:textAllCaps="false"

       android:src="@android:drawable/ic_dialog_email" />
   
   
   </LinearLayout>
   
   </LinearLayout>
   

4. In MainActivity you can use bellow code

   public class MainActivity extends AppCompatActivity {
     ImageView imageView;
     Button button;
     Button btnScan;

       btnScan = (Button)findViewById(R.id.btnScan);
        tv_qr_readTxt = (TextView) findViewById(R.id.tv_qr_readTxt);
   
   button.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View view) {
   
   
   
           if(!editText.getText().toString().isEmpty()){
               EditTextValue = editText.getText().toString();
   
               try {
                   bitmap = TextToImageEncode(EditTextValue);

           }
           else{
               editText.requestFocus();
               Toast.makeText(MainActivity.this, "Please Enter Your Scanned Test" , Toast.LENGTH_LONG).show();
           }
   
         }
     });
   
   
   btnScan.setOnClickListener(new View.OnClickListener() {

You can use the string format operator %, similar to sprintf.

mystring = "%.2f" % 5.5999

Using a collection initializer

From C# 3, you can use collection initializers to construct a List and populate it using a single expression. The following example constructs a Human and its ContactNumbers:

var human = new Human(1, "Address", "Name") {
    ContactNumbers = new List<ContactNumber>() {
        new ContactNumber(1),
        new ContactNumber(2),
        new ContactNumber(3)
    }
}

Specializing the Human constructor

You can change the constructor of the Human class to provide a way to populate the ContactNumbers property:

public class Human
{
    public Human(int id, string address, string name, IEnumerable<ContactNumber> contactNumbers) : this(id, address, name)
    {
        ContactNumbers = new List<ContactNumber>(contactNumbers);
    }

    public Human(int id, string address, string name, params ContactNumber[] contactNumbers) : this(id, address, name)
    {
        ContactNumbers = new List<ContactNumber>(contactNumbers);
    }
}

// Using the first constructor:
List<ContactNumber> numbers = List<ContactNumber>() {
    new ContactNumber(1),
    new ContactNumber(2),
    new ContactNumber(3)
};

var human = new Human(1, "Address", "Name", numbers);

// Using the second constructor:
var human = new Human(1, "Address", "Name",
    new ContactNumber(1),
    new ContactNumber(2),
    new ContactNumber(3)
);

Bottom line

Which alternative is a best practice? Or at least a good practice? You judge it! IMO, the best practice is to write the program as clearly as possible to anyone who has to read it. Using the collection initializer is a winner for me, in this case. With much less code, it can do almost the same things as the alternatives -- at least, the alternatives I gave...

You can find all database names with this:-

 select name from sys.sysdatabases

You can use string formatting:

>>> a=42
>>> b="bar"
>>> "The number is %d and the word is %s" % (a,b)
'The number is 42 and the word is bar'

But this is removed in Python 3, you should use "str.format()":

>>> a=42
>>> b="bar"
>>> "The number is {0} and the word is {1}".format(a,b)
'The number is 42 and the word is bar'

If you're referring to the shell command line, either of the following will work:

node -v

node --version

Just typing node version will cause node.js to attempt loading a module named version, which doesn't exist unless you like working with confusing module names.

The negation operator in Python is not. Therefore just replace your ! with not.

For your example, do this:

if not os.path.exists("/usr/share/sounds/blues") :
    proc = subprocess.Popen(["mkdir", "/usr/share/sounds/blues"])
    proc.wait()

For your specific example (as Neil said in the comments), you don't have to use the subprocess module, you can simply use os.mkdir() to get the result you need, with added exception handling goodness.

Example:

blues_sounds_path = "/usr/share/sounds/blues"
if not os.path.exists(blues_sounds_path):
    try:
        os.mkdir(blues_sounds_path)
    except OSError:
        # Handle the case where the directory could not be created.

It will be very browser dependant. 100 items doesn't sound like a large number - I expect you could go a lot higher than that. Thousands shouldn't be a problem. What may be a problem is the total memory consumption.

foo is used as a place-holder name, usually in example code to signify that the object being named, or the choice of name, is not part of the crux of the example. foo is often followed by bar, baz, and even bundy, if more than one such name is needed. Wikipedia calls these names Metasyntactic Variables. Python programmers supposedly use spam, eggs, ham, instead of foo, etc.

There are good uses of foo in SA.

I have also seen foo used when the programmer can't think of a meaningful name (as a substitute for tmp, say), but I consider that to be a misuse of foo.

After installing python3 with brew install python3 I was getting the error:

Error: An unexpected error occurred during the `brew link` step
The formula built, but is not symlinked into /usr/local
Permission denied @ dir_s_mkdir - /usr/local/Frameworks
Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

After typing brew link python3 the error was:

Linking /usr/local/Cellar/python/3.6.4_3... Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

To solve the problem:

sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/*
brew link python3

After this, I could open python3 by typing python3

.gitkeep isn’t documented, because it’s not a feature of Git.

Git cannot add a completely empty directory. People who want to track empty directories in Git have created the convention of putting files called .gitkeep in these directories. The file could be called anything; Git assigns no special significance to this name.

There is a competing convention of adding a .gitignore file to the empty directories to get them tracked, but some people see this as confusing since the goal is to keep the empty directories, not ignore them; .gitignore is also used to list files that should be ignored by Git when looking for untracked files.

The easier way to accept all accents is this:

[A-zÀ-ú] // accepts lowercase and uppercase characters
[A-zÀ-ÿ] // as above but including letters with an umlaut (includes [ ] ^ \ × ÷)
[A-Za-zÀ-ÿ] // as above but not including [ ] ^ \
[A-Za-zÀ-ÖØ-öø-ÿ] // as above but not including [ ] ^ \ × ÷

See https://unicode-table.com/en/ for characters listed in numeric order.

I created an extension method to the ObservableCollection

public static void MySort<TSource,TKey>(this ObservableCollection<TSource> observableCollection, Func<TSource, TKey> keySelector)
    {
        var a = observableCollection.OrderBy(keySelector).ToList();
        observableCollection.Clear();
        foreach(var b in a)
        {
            observableCollection.Add(b);
        }
    }

It seems to work and you don't need to implement IComparable

Use the sleep command.

Example:

sleep .5 # Waits 0.5 second.
sleep 5  # Waits 5 seconds.
sleep 5s # Waits 5 seconds.
sleep 5m # Waits 5 minutes.
sleep 5h # Waits 5 hours.
sleep 5d # Waits 5 days.

One can also employ decimals when specifying a time unit; e.g. sleep 1.5s

You have two options.

Option 1

Make the menu bar temporarily visible.

• press Alt key and you will be able to see the menu bar

Option 2

Make the menu bar permanently visible.

Steps:

1. Press F1
2. Type user settings
3. Press Enter
4. Click on the { } (top right corner of the window) to open settings.json file see the screenshot
5. Then in the settings.json file, change the value to the default "window.menuBarVisibility": "default" you can see a sample here (or remove this line from JSON file. If you remove any value from the settings.json file then it will use the default settings for those entries. So if you want to make everything to default settings then remove all entries in the settings.json file).

If you don't mind creating an extra date object, you could try:

var tempDate = new Date(parseInt(item.timestamp, 10));
var visitDate = new Date (tempDate.getUTCFullYear(), tempDate.getUTCMonth(), tempDate.getUTCDate());

I do something very similar to get a date of the current month without the time.

Hope it will help to sort out your issue...

To understand why, you need to know that the CPU represents signed numbers using the two's complement (maybe not all, but many).

    byte n = 1; //0000 0001 =  1
    n = ~n + 1; //1111 1110 + 0000 0001 = 1111 1111 = -1

And also, that the type int and unsigned int can be of different sized depending on your CPU. When doing specific stuff like this:

   #include <stdint.h>
   int8_t ibyte;
   uint8_t ubyte;
   int16_t iword;
   //......

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

It's also well worth getting familiar with Commons FileUtils https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FileUtils.html This has additional methods for managing files and often better than JDK.

Generally, setting static field by object instance is a bad practice.

to avoid optional issues you can add synchronized definition, and set it only if private static Logger logger;

@Autowired
public synchronized void setLogger(Logger logger)
{
    if (MyClass.logger == null)
    {
        MyClass.logger = logger;
    }
}

None of the solutions listed worked for me. Instead, I ended up uninstalling and reinstalling Homebrew, which did the trick. Uninstall instructions may be found here: http://osxdaily.com/2018/08/12/how-uninstall-homebrew-mac/

Broken pipe means you wrote to a connection that is already closed by the other end.

isConnected() does not detect this condition. Only a write does.

is it wise to always call SocketChannel.isConnected() before attempting a SocketChannel.write()

It is pointless. The socket itself is connected. You connected it. What may not be connected is the connection itself, and you can only determine that by trying it.

You need #include<string> to use string AND #include<iostream> to use cin and cout. (I didn't get it when I read the answers). Here's some code which works:

#include<string>
#include<iostream>
using namespace std;

int main()
{
    string name;
    cin >> name;
    string message("hi");
    cout << name << message;
    return 0;
}

use this function: void glPolygonMode( GLenum face, GLenum mode);

face : Specifies the polygons that mode applies to. can be GL_FRONT for front side of the polygone and GL_BACK for his back and GL_FRONT_AND_BACK for both.

mode : Three modes are defined and can be specified in mode:

GL_POINT :Polygon vertices that are marked as the start of a boundary edge are drawn as points.

GL_LINE : Boundary edges of the polygon are drawn as line segments. (your target)

GL_FILL : The interior of the polygon is filled.

P.S : glPolygonMode controls the interpretation of polygons for rasterization in the graphics pipeline.

for more information look at the OpenGL reference pages in khronos group : https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glPolygonMode.xhtml

Docker isn't virtualization, as such -- instead, it's an abstraction on top of the kernel's support for different process namespaces, device namespaces, etc.; one namespace isn't inherently more expensive or inefficient than another, so what actually makes Docker have a performance impact is a matter of what's actually in those namespaces.

Docker's choices in terms of how it configures namespaces for its containers have costs, but those costs are all directly associated with benefits -- you can give them up, but in doing so you also give up the associated benefit:

• Layered filesystems are expensive -- exactly what the costs are vary with each one (and Docker supports multiple backends), and with your usage patterns (merging multiple large directories, or merging a very deep set of filesystems will be particularly expensive), but they're not free. On the other hand, a great deal of Docker's functionality -- being able to build guests off other guests in a copy-on-write manner, and getting the storage advantages implicit in same -- ride on paying this cost.
• DNAT gets expensive at scale -- but gives you the benefit of being able to configure your guest's networking independently of your host's and have a convenient interface for forwarding only the ports you want between them. You can replace this with a bridge to a physical interface, but again, lose the benefit.
• Being able to run each software stack with its dependencies installed in the most convenient manner -- independent of the host's distro, libc, and other library versions -- is a great benefit, but needing to load shared libraries more than once (when their versions differ) has the cost you'd expect.

And so forth. How much these costs actually impact you in your environment -- with your network access patterns, your memory constraints, etc -- is an item for which it's difficult to provide a generic answer.

This is a well-known problem with Java type erasure: T is just a type variable, and you must indicate actual class, usually as Class argument. Without such information, best that can be done is to use bounds; and plain T is roughly same as 'T extends Object'. And Jackson will then bind JSON Objects as Maps.

In this case, tester method needs to have access to Class, and you can construct

JavaType type = mapper.getTypeFactory().
  constructCollectionType(List.class, Foo.class)

and then

List<Foo> list = mapper.readValue(new File("input.json"), type);

The YML standard does not specify a way to do this. And this problem does not limit itself to YML. JSON has the same limitations.

Many applications which use YML or JSON based configurations run into this problem eventually. And when that happens, they make up their own convention.

e.g. for swagger API definitions:

$ref: 'file.yml'

e.g. for docker compose configurations:

services:
  app:
    extends:
      file: docker-compose.base.yml

Alternatively, if you want to split up the content of a yml file in multiple files, like a tree of content, you can define your own folder-structure convention and use an (existing) merge script.

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

using timedeltas you can do:

import datetime
today=datetime.date.today()


time=datetime.time()
print("today :",today)

# One day different .
five_day=datetime.timedelta(days=5)
print("one day :",five_day)
#output - 1 day , 00:00:00


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)
#output - 
today : 2019-05-29
one day : 5 days, 0:00:00
fitfthday 2019-06-03

Try using the following pattern in scanf. It will read until the end of the line:

scanf("%d\n", &n)

You won't need the getchar() inside the loop since scanf will read the whole line. The floats won't match the scanf pattern and the prompt will ask for an integer again.

I kept using this all this time

After doing the git rm --cached command, try adding myfile to the .gitignore file (create one if it does not exist). This should tell git to ignore myfile.

The .gitignore file is versioned, so you'll need to commit it and push it to the remote repository.

With the header function. There is an example in the section on the first parameter it takes.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

"As of Android 1.6, incoming SMS message broadcasts (android.provider.Telephony.SMS_RECEIVED) are delivered as an "ordered broadcast" — meaning that you can tell the system which components should receive the broadcast first."

This means that you can intercept incoming message and abort broadcasting of it further on.

In your AndroidManifest.xml file, make sure to have priority set to highest:

<receiver android:name=".receiver.SMSReceiver" android:enabled="true">
    <intent-filter android:priority="1000">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

In your BroadcastReceiver, in onReceive() method, before performing anything with your message, simply call abortBroadcast();

EDIT: As of KitKat, this doesn't work anymore apparently.

EDIT2: More info on how to do it on KitKat here:

I think you can also think of alternative architectures. Sometimes something can be done in another way much more easier. If the producer of HTML file is you, then you can write an HTTP handler to create an Excel document on the server (which is much more easier than in JavaScript) and send a file to the client. If you receive that HTML file from somewhere (like an HTML version of a report), then you still can use a server side language like C# or PHP to create the Excel file still very easily. I mean, you may have other ways too. :)

Congratulation ! ¨^^ I have an easy & efficient solution for you, yes!

<iframe width="100%" height="300" [attr.src]="video.url"></iframe

[attr.src] instead of src "video.url" and not {{video.url}}

Great ;)

Check your entitlements against your app bundle id. It is probable it is not the same.

The way this still do not work is when I export for testing in my device but in Release mode.

That work to me.

I know this is old, but if anyone else wants to know why they get incomplete json like above is because the ampersand & is a special character in URLs used to separate parameters.
In your data there is an ampersand in R&R. So the acc parameter ends when it reaches the ampersand character.

That's why you are getting chopped data. The solution is either url encode the data or send as POST like the accepted solution suggests.

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}
