Also, do not forget to import the MaterialModule in the imports array of AppModule.

invalidate cache in android studio will resolve this issue. Go to file-> click on invalidate cache/restart option.

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

Its just better to create a routing component that would handle all your routes! From the angular website documentation! That's good practice!

ng generate module app-routing --flat --module=app

The above CLI generates a routing module and adds to your app module, all you need to do from the generated component is to declare your routes, also don't forget to add this:

exports: [
    RouterModule
  ],

to your ng-module decorator as it doesn't come with the generated app-routing module by default!

In my case, my app had multiple layers of modules, so the module I was trying to import had to be added into the module parent that actually used it pages.module.ts, instead of app.module.ts.

In your components.module.ts you should import IonicModule like this:

import { IonicModule } from '@ionic/angular';

Then import IonicModule like this:

  imports: [
    CommonModule,
    IonicModule
  ],

so your components.module.ts will be like this:

import { CommonModule } from '@angular/common';
import {PostComponent} from './post/post.component'
import { IonicModule } from '@ionic/angular';

@NgModule({
  declarations: [PostComponent],
  imports: [
    CommonModule,
    IonicModule
  ],
  exports: [PostComponent]
})
export class ComponentsModule { }```

I faced this problem too. Re-ran the Visual Studio 2017 Installer, go to 'Individual Components' and select Windows 8.1 SDK. Go back to to the project > Right click and Re-target to match the SDK required as shown below:

If anyone's still stuck on this, the easiest solution I found was to "Retarget Solution". In my case, the project was built of SDK 8.1, upgrading to VS2017 brought with it SDK 10.0.xxx.

To retarget solution: Project->Retarget Solution->"Select whichever SDK you have installed"->OK

From there on you can simply build/debug your solution. Hope it helps

I had to add this line in the ConfigureServices in order to work.

services.AddSingleton<IOrderService, OrderService>();

This feature is called "strict null checks", to turn it off ensure that the --strictNullChecks compiler flag is not set.

However, the existence of null has been described as The Billion Dollar Mistake, so it is exciting to see languages such as TypeScript introducing a fix. I'd strongly recommend keeping it turned on.

One way to fix this is to ensure that the values are never null or undefined, for example by initialising them up front:

interface SelectProtected {
    readonly wrapperElement: HTMLDivElement;
    readonly inputElement: HTMLInputElement;
}

const selectProtected: SelectProtected = {
    wrapperElement: document.createElement("div"),
    inputElement: document.createElement("input")
};

See Ryan Cavanaugh's answer for an alternative option, though!

Just read this post and according to the angular 2 docs:

export CUSTOM_ELEMENTS_SCHEMA
Defines a schema that will allow:

any non-Angular elements with a - in their name,
any properties on elements with a - in their name which is the common rule for custom elements.

So just in case anyone runs into this problem, once you have added CUSTOM_ELEMENTS_SCHEMA to your NgModule, make sure that whatever new custom element you use has a 'dash' in its name eg. or etc.

Angular RC5 & RC6

If you are getting the above mentioned error in your Jasmine tests, it is most likely because you have to declare the unrenderable component in your TestBed.configureTestingModule({}).

The TestBed configures and initializes an environment for unit testing and provides methods for mocking/creating/injecting components and services in unit tests.

If you don't declare the component before your unit tests are executed, Angular will not know what <courses></courses> is in your template file.

Here is an example:

import {async, ComponentFixture, TestBed} from "@angular/core/testing";
import {AppComponent} from "../app.component";
import {CoursesComponent} from './courses.component';

describe('CoursesComponent', () => {
  let component: CoursesComponent;
  let fixture: ComponentFixture<CoursesComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        AppComponent,
        CoursesComponent
      ],
      imports: [
        BrowserModule
        // If you have any other imports add them here
      ]
    })
    .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(CoursesComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

For me path for templateUrl was not correct

I was using

shopping-list-edit.component.html

Whereas it should have been

./shopping-list-edit.component.html

Silly mistake but happens when starting out. Hope that helps somebody in distress.

I have disabled Instant Run feature from the preferences and the issue was solved.

I was getting this error even when all the relevant dependencies were in place because I hadn't created the schema in MySQL.

I thought it would be created automatically but it wasn't. Although the table itself will be created, you have to create the schema.

The version I'm using I think is the good one, since is the exact same as the Android Developer Docs, except for the name of the string, they used "view" and I used "webview", for the rest is the same

No, it is not.

The one that is new to the N Developer Preview has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request)

The one that is supported by all Android versions, including N, has this method signature:

public boolean shouldOverrideUrlLoading(WebView view, String url)

So why should I do to make it work on all versions?

Override the deprecated one, the one that takes a String as the second parameter.

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.

Quick solution that worked like a charm for me and others:

If you are using VS 2015+, just remove the following lines from the .csproj file of your project:

  <Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
  </Target>

In VS 2015+ Solution Explorer:

1. Right-click project name -> Unload Project
2. Right-click project name -> Edit .csproj
3. Remove the lines specified above from the file and save
4. Right-click project name -> Reload Project

EDIT : Works with design library upto 23.0.1 but doesn't work on 23.1.0

In main layout xml you will have NavigationView defined, in that use app:headerLayout to set the header view.

<android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/nav_drawer_header"
        app:menu="@menu/navigation_drawer_menu" />

And the @layout/nav_drawer_header will be the place holder of the image and texts.

nav_drawer_header.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="170dp"
android:orientation="vertical">

<RelativeLayout
    android:id="@+id/headerRelativeLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scaleType="fitXY"
        android:src="@drawable/background" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="@dimen/action_bar_size"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:background="#40000000"
        android:gravity="center"
        android:orientation="horizontal"
        android:paddingBottom="5dp"
        android:paddingLeft="16dp"

            android:layout_height="match_parent"
            android:layout_marginLeft="35dp"
            android:orientation="vertical"
            android:weightSum="2">


            <TextView
                android:id="@+id/navHeaderTitle"
                android:layout_width="wrap_content"
                android:layout_height="0dp"
                android:layout_weight="1"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:textColor="@android:color/white" />

            <TextView
                android:id="@+id/navHeaderSubTitle"
                android:layout_width="wrap_content"
                android:layout_height="0dp"
                android:layout_weight="1"
                android:textAppearance="?android:attr/textAppearanceSmall"
                android:textColor="@android:color/white" />

        </LinearLayout>

    </LinearLayout>
</RelativeLayout>
</LinearLayout>

And in your main class, you can take handle of Imageview and TextView as like normal other views.

TextView navHeaderTitle = (TextView) findViewById(R.id.navHeaderTitle);
navHeaderTitle.setText("Application Name");

TextView navHeaderSubTitle = (TextView) findViewById(R.id.navHeaderSubTitle);
navHeaderSubTitle.setText("Application Caption");

Hope this helps.

You can't, because the only way you could do it without parentheses is having it be a keyword, like in Python 2. You can't manually define a keyword, so no.

UPDATE 24.04.2016.

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)

EDIT

I've tested this on Twenty Fifteen and it's working, so it should be working for you.

In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:

    <div id="ajax-posts" class="row">
        <?php
            $postsPerPage = 3;
            $args = array(
                    'post_type' => 'post',
                    'posts_per_page' => $postsPerPage,
                    'cat' => 8
            );

            $loop = new WP_Query($args);

            while ($loop->have_posts()) : $loop->the_post();
        ?>

         <div class="small-12 large-4 columns">
                <h1><?php the_title(); ?></h1>
                <p><?php the_content(); ?></p>
         </div>

         <?php
                endwhile;
        wp_reset_postdata();
         ?>
    </div>
    <div id="more_posts">Load More</div>

This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with

$cat_id = get_query_var('cat');

This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like

<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>

And pull the category with

var cat = $('#more_posts').data('category');

But for now, you can leave this out.

Next in functions.php I added

wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
    'ajaxurl' => admin_url( 'admin-ajax.php' ),
    'noposts' => __('No older posts found', 'twentyfifteen'),
));

Right after the existing wp_localize_script. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.

At the end of the functions.php file I added the function that will load your posts:

function more_post_ajax(){

    $ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
    $page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;

    header("Content-Type: text/html");

    $args = array(
        'suppress_filters' => true,
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'cat' => 8,
        'paged'    => $page,
    );

    $loop = new WP_Query($args);

    $out = '';

    if ($loop -> have_posts()) :  while ($loop -> have_posts()) : $loop -> the_post();
        $out .= '<div class="small-12 large-4 columns">
                <h1>'.get_the_title().'</h1>
                <p>'.get_the_content().'</p>
         </div>';

    endwhile;
    endif;
    wp_reset_postdata();
    die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.

If you've added your category in the loader, you'd add:

$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';

And instead of 8, you'd put $cat. This will be in the $_POST array, and you'll be able to use it in ajax.

Last part is the ajax itself. In functions.js I put inside the $(document).ready(); enviroment

var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;


function load_posts(){
    pageNumber++;
    var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
    $.ajax({
        type: "POST",
        dataType: "html",
        url: ajax_posts.ajaxurl,
        data: str,
        success: function(data){
            var $data = $(data);
            if($data.length){
                $("#ajax-posts").append($data);
                $("#more_posts").attr("disabled",false);
            } else{
                $("#more_posts").attr("disabled",true);
            }
        },
        error : function(jqXHR, textStatus, errorThrown) {
            $loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
        }

    });
    return false;
}

$("#more_posts").on("click",function(){ // When btn is pressed.
    $("#more_posts").attr("disabled",true); // Disable the button, temp.
    load_posts();
});

Saved it, tested it, and it works :)

Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD

UPDATE

For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;) you can try with

$(window).on('scroll', function () {
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

This should run the load_posts() function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer

$(window).on('scroll', function(){
    if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
        if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
                load_posts();
        }
    }
});

Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100 or $('footer').offset().top for some reason. If that should happen, just increase the number where the scroll goes to.

You can easily check it by putting console.logs in your code and see in the inspector what they throw out

$(window).on('scroll', function () {
    console.log($(window).scrollTop() + $(window).height());
    console.log($(document).height() - 100);
    if ($(window).scrollTop() + $(window).height()  >= $(document).height() - 100) {
        load_posts();
    }
});

And just adjust accordingly ;)

Hope this helps :) If you have any questions just ask.

I really suggest following Google's Design Guidelines:

which says "Notification icons must be entirely white."

http://jdpgrailsdev.github.io/blog/2014/09/09/spring_data_hibernate_join.html
from this link:

if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOINHowever, if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOIN.

The Spring Data JPA library provides a Domain Driven Design Specifications API that allows you to control the behavior of the generated query.

final long userId = 1;

final Specification<User> spec = new Specification<User>() {
   @Override
    public Predicate toPredicate(final Root<User> root, final 
     CriteriaQuery<?> query, final CriteriaBuilder cb) {
    query.distinct(true);
    root.fetch("permissions", JoinType.LEFT);
    return cb.equal(root.get("id"), userId);
 }
};

List<User> users = userRepository.findAll(spec);

Why not using pyvmomi original function SmartConnectNoSSL. They added this function on June 14, 2016 and named it ConnectNoSSL, one day after they changed the name to SmartConnectNoSSL, use that instead of by passing the warning with unnecessary lines of code in your project?

Provides a standard method for connecting to a specified server without SSL verification. Useful when connecting to servers with self-signed certificates or when you wish to ignore SSL altogether

service_instance = connect.SmartConnectNoSSL(host=args.ip,
                                             user=args.user,
                                             pwd=args.password)

There are three options, that you can use. -I is to exclude binary files in grep. Other are for line numbers and file names.

grep -I -n -H 


-I -- process a binary file as if it did not contain matching data; 
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match

So this might be a way to run grep:

grep -InH your-word *

in your servlet

 request.setAttribute("submitDone","done");
 return mapping.findForward("success");

In your jsp

<c:if test="${not empty submitDone}">
  <script>alert("Form submitted");
</script></c:if>

use this code it is working

I hit this problem because I had: project A (a desktop .exe) refer to project B (a portable .dll). A & B had different versions of JSON.Net, and so there was a loader conflict. Once I made all the versions of JSON.net the same, it worked. (This is in effect what some of the solutions above are doing - I'm just calling out why it works)

Not sure why none of these are marked as the correct answer, but I landed here through a google search, so I will pass along what I know...

@paul_g's method was pretty close for me, my steps on a Mac osx10.9 Retina:

• Install macports
• Install rvm (stable with ruby add --insecure flag for SSL related issues) $\curl -sSL --insecure https://get.rvm.io | bash -s stable --ruby
• Restart Terminal / Resource your profile
• Run rvm requirements --with-gcc=clang You won't have to update Ruby because you downloaded the last stable version
• And last step to run gem install compass --pre

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

If you want to style the output of a data frame in a jupyter notebook cell, you can set the display style on a per-dataframe basis:

df = pd.DataFrame({'A': np.random.randn(4)*1e7})
df.style.format("{:.1f}")

See the documentation here.

Here's how I got my bash script for my daily mysqldump database backups to work more securely. This is an expansion of Cristian Porta's great answer.

1. First use mysql_config_editor (comes with mysql 5.6+) to set up the encrypted password file. Suppose your username is "db_user". Running from the shell prompt:

   mysql_config_editor set --login-path=local --host=localhost --user=db_user --password
   

   It prompts for the password. Once you enter it, the user/pass are saved encrypted in your home/system_username/.mylogin.cnf

   Of course, change "system_username" to your username on the server.

2. Change your bash script from this:

   mysqldump -u db_user -pInsecurePassword my_database | gzip > db_backup.tar.gz
   

   to this:

   mysqldump --login-path=local my_database | gzip > db_backup.tar.gz
   

No more exposed passwords.

You're attempting to free something that isn't a pointer to a "freeable" memory address. Just because something is an address doesn't mean that you need to or should free it.

There are two main types of memory you seem to be confusing - stack memory and heap memory.

• Stack memory lives in the live span of the function. It's temporary space for things that shouldn't grow too big. When you call the function main, it sets aside some memory for your variables you've declared (p,token, and so on).

• Heap memory lives from when you malloc it to when you free it. You can use much more heap memory than you can stack memory. You also need to keep track of it - it's not easy like stack memory!

You have a few errors:

• You're trying to free memory that's not heap memory. Don't do that.

• You're trying to free the inside of a block of memory. When you have in fact allocated a block of memory, you can only free it from the pointer returned by malloc. That is to say, only from the beginning of the block. You can't free a portion of the block from the inside.

For your bit of code here, you probably want to find a way to copy relevant portion of memory to somewhere else...say another block of memory you've set aside. Or you can modify the original string if you want (hint: char value 0 is the null terminator and tells functions like printf to stop reading the string).

EDIT: The malloc function does allocate heap memory*.

"9.9.1 The malloc and free Functions

The C standard library provides an explicit allocator known as the malloc package. Programs allocate blocks from the heap by calling the malloc function."

~Computer Systems : A Programmer's Perspective, 2nd Edition, Bryant & O'Hallaron, 2011

EDIT 2: * The C standard does not, in fact, specify anything about the heap or the stack. However, for anyone learning on a relevant desktop/laptop machine, the distinction is probably unnecessary and confusing if anything, especially if you're learning about how your program is stored and executed. When you find yourself working on something like an AVR microcontroller as H2CO3 has, it is definitely worthwhile to note all the differences, which from my own experience with embedded systems, extend well past memory allocation.

If you don't have 'HIBERNATE_SEQUENCE' sequence created in database (if use oracle or any sequence based database), you shall get same type of error;

Ensure the sequence is present there;

You are not changing the value of line. It should be something like this.

import java.io.BufferedReader;
import java.io.FileReader;

public class InsertValuesIntoTestDb {

  @SuppressWarnings("rawtypes")
  public static void main(String[] args) throws Exception {
      String splitBy = ",";
      BufferedReader br = new BufferedReader(new FileReader("test.csv"));
      while((line = br.readLine()) != null){
           String[] b = line.split(splitBy);
           System.out.println(b[0]);
      }
      br.close();

  }
}

readLine returns each line and only returns null when there is nothing left. The above code sets line and then checks if it is null.

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

I just restarted Visual Studio and did IISRESET which solved the problem.

Every one has written an answer but I am still surprised that nobody actually answered it by using the best simple way.
The people answer that include the jar file. But, the error will still occur.

The reason for that is, the jar is not deployed when the project is run. So, what we need to do is, tell the IDE to deploy this jar also.

The people here has answered so many times that put that jar file in the lib folder of WEB-INF. That seems okay, but why do it manually. There is simple way. Check the below steps:

Step 1: If you haven't referenced the jar file into the project then, reference it like this.

Right click on the project and go to the project properties. Then, go to the java build path, then add external jar file via that.

But this will still not solve the problem because adding the external jar via build path only helps in compiling the classes, and the jar will not be deployed when you run the project. For that follow this step

Right click on the project and go to the project properties. Then, go to the Deployment Assembly then press Add , then go to the java build path entries and add your libraries whether it is jstl, mysql or any other jar file. add them to deployment. Below are the two pictures which display it.

You're thinking too complicated. It's actually just $('#'+openaddress).

Use decode:

print(curses.version.decode())
# 2.2

You want options(warn=-1). However, note that warn=0 is not the safest warning level and it should not be assumed as the current one, particularly within scripts or functions. Thus the safest way to temporary turn off warnings is:

oldw <- getOption("warn")
options(warn = -1)

[your "silenced" code]

options(warn = oldw)

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

I found the best solution here, the key of this issue is the addEntity method

public static void testSimpleSQL() {
    final Session session = sessionFactory.openSession();
    SQLQuery q = session.createSQLQuery("select * from ENTITY");
    q.addEntity(Entity.class);
    List<Entity> entities = q.list();
    for (Entity entity : entities) {
        System.out.println(entity);
    }
}

@bdiamante's answer may only partially help you. If you still get a message after you've suppressed warnings, it's because the pandas library itself is printing the message. There's not much you can do about it unless you edit the Pandas source code yourself. Maybe there's an option internally to suppress them, or a way to override things, but I couldn't find one.

For those who need to know why...

Suppose that you want to ensure a clean working environment. At the top of your script, you put pd.reset_option('all'). With Pandas 0.23.4, you get the following:

>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning: html.bord
er has been deprecated, use display.html.border instead
(currently both are identical)

  warnings.warn(d.msg, FutureWarning)

: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning:
: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

  warnings.warn(d.msg, FutureWarning)

>>>

Following the @bdiamante's advice, you use the warnings library. Now, true to it's word, the warnings have been removed. However, several pesky messages remain:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=FutureWarning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In fact, disabling all warnings produces the same output:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=Warning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In the standard library sense, these aren't true warnings. Pandas implements its own warnings system. Running grep -rn on the warning messages shows that the pandas warning system is implemented in core/config_init.py:

$ grep -rn "html.border has been deprecated"
core/config_init.py:207:html.border has been deprecated, use display.html.border instead

Further chasing shows that I don't have time for this. And you probably don't either. Hopefully this saves you from falling down the rabbit hole or perhaps inspires someone to figure out how to truly suppress these messages!

This is called fire and forget, and there is an extension for that.

Consumes a task and doesn't do anything with it. Useful for fire-and-forget calls to async methods within async methods.

Install nuget package.

Use:

MyAsyncMethod().Forget();

i solved problem changing my.ini file located in data folder. for mysql 5.6 my.ini file moved to data folder rather the bin or mysql installation folder.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Here $users is a PDOStatement object over which you can iterate. The first iteration outputs all results, the second does nothing since you can only iterate over the result once. That's because the data is being streamed from the database and iterating over the result with foreach is essentially shorthand for:

while ($row = $users->fetch()) ...

Once you've completed that loop, you need to reset the cursor on the database side before you can loop over it again.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
$result = $users->fetch(PDO::FETCH_ASSOC);
foreach($result as $key => $value) {
    echo $key . "-" . $value . "<br/>";
}

Here all results are being output by the first loop. The call to fetch will return false, since you have already exhausted the result set (see above), so you get an error trying to loop over false.

In the last example you are simply fetching the first result row and are looping over it.

Use -Wno-unused-variable should work.

You can use like this

 EditText dollar=(EditText) findViewById(R.id.money);
 int rupees=Integer.parseInt( dollar.getText().toString());

(I don't have enough rep points to add a comment, but I want to add some clarity on the answers here)

Application.AskToUpdateLinks = False is probably not what you want.

If set to False, then MS Excel will attempt to update the links automatically it just won't prompt the user beforehand, sorta counter-intuitive.

The correct solution, if you're looking to open a file without updating links should be:

Workbook.Open(UpdateLinks:=0)

Related link: Difference in AskToUpdateLinks=False and UpdateLinks:=0

If you know what are the useless warnings you usually encounter, you can filter them by message.

import warnings

#ignore by message
warnings.filterwarnings("ignore", message="divide by zero encountered in divide")

#part of the message is also okay
warnings.filterwarnings("ignore", message="divide by zero encountered") 
warnings.filterwarnings("ignore", message="invalid value encountered")

In my case, when using IntelliJ, I had multiple modules in the project. The main module was dependent on another module which had the maven dependencies on Spring.

The main module had Entitys and so did the second module. But when I ran the main module, only the Entitys from the second module got recognized as managed classes.

I then added Spring dependencies on the main module as well, and guess what? It recognized all the Entitys.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

tools:ignore="ProtectedPermissions"

Try adding this attribute to that permission.

Yes, there is a way. Two in fact. In October 2013 jshint added a way to ignore blocks of code like this:

// Code here will be linted with JSHint.
/* jshint ignore:start */
// Code here will be ignored by JSHint.
/* jshint ignore:end */
// Code here will be linted with JSHint.

You can also ignore a single line with a trailing comment like this:

ignoreThis(); // jshint ignore:line

I had the same problem after upgrading a bunch of NuGet packages.
I have tried all kinds of deleting, cleaning, resintalling described here and beyong to no avail. The references did not have Microsoft.Web.Infrastructure despite the NuGet manager showed it was installed.

The problem was solved by replacing:

  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45" />

with

  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net46" />

in packages.config. The culprit is apparently "net45".

I deactivated my "Arno's Iptables Firewall" for testing, and then the messages are gone

Change this line

First try to open the file with a decompiler such as ILSpy, your dll might be corrupt. I had this error on an online web site, when I downloaded the dll and tried to open it, it was corrupt, probably some error occurred while uploading it via ftp.

Because python 3 print() function allows end="" definition, that satisfies the majority of issues.

In my case, I wanted to PrettyPrint and was frustrated that this module wasn't similarly updated. So i made it do what i wanted:

from pprint import PrettyPrinter

class CommaEndingPrettyPrinter(PrettyPrinter):
    def pprint(self, object):
        self._format(object, self._stream, 0, 0, {}, 0)
        # this is where to tell it what you want instead of the default "\n"
        self._stream.write(",\n")

def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None):
    """Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end."""
    printer = CommaEndingPrettyPrinter(
        stream=stream, indent=indent, width=width, depth=depth)
    printer.pprint(object)

Now, when I do:

comma_ending_prettyprint(row, stream=outfile)

I get what I wanted (substitute what you want -- Your Mileage May Vary)

The dialog needs to be started only after the window states of the Activity are initialized This happens only after onresume.

So call

runOnUIthread(new Runnable(){

    showInfoMessageDialog("Please check your network connection","Network Alert");
});

in your OnResume function. Do not create dialogs in OnCreate
Edit:

use this

Handler h = new Handler();

h.postDelayed(new Runnable(){

        showInfoMessageDialog("Please check your network connection","Network Alert");
    },500);

in your Onresume instead of showonuithread

Well there's a problem with the creation of the ContactServiceImpl bean. First, make sure that the class is actually instantiated by debugging the no-args constructor when the Spring context is initiated and when an instance of ContactController is created.

If the ContactServiceImpl is actually instantiated by the Spring context, but it's simply not matched against your @Autowire annotation, try being more explicit in your annotation injection. Here's a guy dealing with a similar problem as yours and giving some possible solutions:

http://blogs.sourceallies.com/2011/08/spring-injection-with-resource-and-autowired/

If you ask me, I think you'll be ok if you replace

@Autowired
private ContactService contactService;

with:

@Resource
@Qualifier("contactService")
private ContactService contactService;

The error shows you either didn't create the rails project yet or you're not in the rails project directory.

Suppose if you're working on myapp project. You've to move to that project directory on your command line and then generate the model. Here are some steps you can refer.

Example: Assuming you didn't create the Rails app yet:

$> rails new myapp
$> cd myapp

Now generate the model from your commandline.

$> rails generate model your_model_name 

If you are using Gradle add this:

You can simply do the following steps,

• You can change the options for pandas max_columns feature as follows

  import pandas as pd
  pd.options.display.max_columns = 10
  

  (this allows 10 columns to display, you can change this as you need)

• Like that you can change the number of rows as you need to display as follows (if you need to change maximum rows as well)

  pd.options.display.max_rows = 999
  

  (this allows to print 999 rows at a time)

Please kindly refer the doc to change different options/settings for pandas

You need to include SOAPAction as a header in the request. As you have httpPost and requestWrapper handles, there are three ways adding the header.

 1. httpPost.addHeader( "SOAPAction", strReferenceToSoapActionValue );
 2. httpPost.setHeader( "SOAPAction", strReferenceToSoapActionValue );
 3. requestWrapper.setHeader( "SOAPAction", strReferenceToSoapActionValue );

Only difference is that addHeader allows multiple values with same header name and setHeader allows unique header names only. setHeader(... over writes first header with the same name.

You can go with any of these on your requirement.

If you are testing asynchronous code, you need to make sure to place done() in the callback of that asynchronous code. I had that issue when testing http requests to a REST API.

I think you could use Spring's

@Lazy

annotation on one of the autowired fields to break circular dependency.

I'm not sure if this works/exists in mentioned Spring version.

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

Python Force-suppress all exponential notation when printing numpy ndarrays, wrangle text justification, rounding and print options:

What follows is an explanation for what is going on, scroll to bottom for code demos.

Passing parameter suppress=True to function set_printoptions works only for numbers that fit in the default 8 character space allotted to it, like this:

import numpy as np
np.set_printoptions(suppress=True) #prevent numpy exponential 
                                   #notation on print, default False

a = np.array([1.01e-5, 22, 1.2345678e7])  #notice how index 2 is 8 
                                          #digits wide

print(a)    #prints [ 0.0000101   22.     12345678. ]

However if you pass in a number greater than 8 characters wide, exponential notation is imposed again, like this:

np.set_printoptions(suppress=True)

a = np.array([1.01e-5, 22, 1.2345678e10])    #notice how index 2 is 10
                                             #digits wide, too wide!

#exponential notation where we've told it not to!
print(a)    #prints [1.01000000e-005   2.20000000e+001   1.23456780e+10]

numpy has a choice between chopping your number in half thus misrepresenting it, or forcing exponential notation, it chooses the latter.

Here comes set_printoptions(formatter=...) to the rescue to specify options for printing and rounding. Tell set_printoptions to just print bare a bare float:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:f}'.format})

a = np.array([1.01e-5, 22, 1.2345678e30])  #notice how index 2 is 30
                                           #digits wide.  

#Ok good, no exponential notation in the large numbers:
print(a)  #prints [0.000010 22.000000 1234567799999999979944197226496.000000] 

We've force-suppressed the exponential notation, but it is not rounded or justified, so specify extra formatting options:

np.set_printoptions(suppress=True,
   formatter={'float_kind':'{:0.2f}'.format})  #float, 2 units 
                                               #precision right, 0 on left

a = np.array([1.01e-5, 22, 1.2345678e30])   #notice how index 2 is 30
                                            #digits wide

print(a)  #prints [0.00 22.00 1234567799999999979944197226496.00]

The drawback for force-suppressing all exponential notion in ndarrays is that if your ndarray gets a huge float value near infinity in it, and you print it, you're going to get blasted in the face with a page full of numbers.

Notice that rounding is consistent at 2 units precision, and exponential notation is suppressed in both the very large e+x and very small e-x ranges.

Iv'd found 2 solutions to the problem, which its implied that you detect touch with modernizr or something else and set a touch class on the html element.

This is good but not supported very well:

html.touch *:hover {
    all:unset!important;
}

But this has a very good support:

html.touch *:hover {
    pointer-events: none !important;
}

Works flawless for me, it makes all the hover effects be like when you have a touch on a button it will light up but not end up buggy as the initial hover effect for mouse events.

Detecting touch from no-touch devices i think modernizr has done the best job:

https://github.com/Modernizr/Modernizr/blob/master/feature-detects/touchevents.js

EDIT

I found a better and simpler solution to this issue

How to determine if the client is a touch device

Android will not let you do this for security concerns. An evil developer could very easily steal user-entered login information.

Instead, you have to catch the text being displayed in the webview before it is displayed. If you don't want to set up a response handler (as per the other answers), I found this fix with some googling:

URL url = new URL("https://stackoverflow.com/questions/1381617");
URLConnection con = url.openConnection();
Pattern p = Pattern.compile("text/html;\\s+charset=([^\\s]+)\\s*");
Matcher m = p.matcher(con.getContentType());
/* If Content-Type doesn't match this pre-conception, choose default and 
 * hope for the best. */
String charset = m.matches() ? m.group(1) : "ISO-8859-1";
Reader r = new InputStreamReader(con.getInputStream(), charset);
StringBuilder buf = new StringBuilder();
while (true) {
  int ch = r.read();
  if (ch < 0)
    break;
  buf.append((char) ch);
}
String str = buf.toString();

This is a lot of code, and you should be able to copy/paster it, and at the end of it str will contain the same html drawn in the webview. This answer is from Simplest way to correctly load html from web page into a string in Java and it should work on Android as well. I have not tested this and did not write it myself, but it might help you out.

Also, the URL this is pulling is hardcoded, so you'll have to change that.

I can also propose following solution for C++11.

for (auto p = 0U; p < sys.size(); p++) {

}

(C++ is not smart enough for auto p = 0, so I have to put p = 0U....)

I made a function out of @arnep 's idea:

echo|set /p="Hello World"

here it is:

:SL (sameline)
echo|set /p=%1
exit /b

Use it with call :SL "Hello There"
I know this is nothing special but it took me so long to think of it I figured I'd post it here.

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

If you know that the Integer is not NULL, you can simply do this:

Integer intVal = 1;
Long longVal = (long) (int) intVal

You didn't say what version you were using, but in SQL 2005 and above, you can use a common table expression with the OVER Clause. It goes a little something like this:

WITH cte AS (
  SELECT[foo], [bar], 
     row_number() OVER(PARTITION BY foo, bar ORDER BY baz) AS [rn]
  FROM TABLE
)
DELETE cte WHERE [rn] > 1

Play around with it and see what you get.

(Edit: In an attempt to be helpful, someone edited the ORDER BY clause within the CTE. To be clear, you can order by anything you want here, it needn't be one of the columns returned by the cte. In fact, a common use-case here is that "foo, bar" are the group identifier and "baz" is some sort of time stamp. In order to keep the latest, you'd do ORDER BY baz desc)

You can use format or formatC to, ahem, format your axis labels.

For whole numbers, try

x <- 10 ^ (1:10)
format(x, scientific = FALSE)
formatC(x, digits = 0, format = "f")

If the numbers are convertable to actual integers (i.e., not too big), you can also use

formatC(x, format = "d")

How you get the labels onto your axis depends upon the plotting system that you are using.

Using --disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files switch?

Before using these commands be sure to end all running instances of Chrome.

In the properties for your pydev project, there's a pane called "PyDev - PYTHONPATH", with a sub-pane called "External Libraries". You can add source folders (any folder that has an __init__.py) to the path using that pane. Your project code will then be able to import modules from those source folders.

I usually write a macro like this:

#define UNUSED(x) (void)(x)

You can use this macro for all your unused parameters. (Note that this works on any compiler.)

For example:

void f(int x) {
    UNUSED(x);
    ...
}

Probably you try to send your data from mydomain.com to www.mydomain.com or reverse, NOTE you missed "www". http://mydomain.com and http://www.mydomain.com are different domains to javascript.

There are a million ways to do this.

The first one would be to go ahead and run the array through foreach anyway, assuming you do have an array.

In other cases this is what you might need:

foreach ((array) $items as $item) {
    print $item;

Note: to all the people complaining about typecast, please note that the OP asked cleanest way to skip a foreach if array is empty (emphasis is mine). A value of true, false, numbers or strings is not considered empty. In addition, this would work with objects implementing \Traversable, whereas is_array wouldn't work.

Just go to http://technet.microsoft.com/en-us/library/bb491035.aspx

Here's what the MAIN ISSUE is "... If Destination does not contain an existing directory and does not end with a backslash (), the following message appears: ...

Does destination specify a file name or directory name on the target (F = file, D = directory)?

You can suppress this message by using the /i command-line option, which causes xcopy to assume that the destination is a directory if the source is more than one file or a directory.

Took me a while, but all it takes is RTFM.

It isn't clear why you want to do this without sink, but you can wrap any commands in the invisible() function and it will suppress the output. For instance:

1:10 # prints output
invisible(1:10) # hides it

Otherwise, you can always combine things into one line with a semicolon and parentheses:

{ sink("/dev/null"); ....; sink(); }

To expound on cletus' answer, at runtime all record of the generic types is removed. Generics are processed only in the compiler and are used to provide additional type safety. They are really just shorthand that allows the compiler to insert typecasts at the appropriate places. For example, previously you'd have to do the following:

List x = new ArrayList();
x.add(new SomeClass());
Iterator i = x.iterator();
SomeClass z = (SomeClass) i.next();

becomes

List<SomeClass> x = new ArrayList<SomeClass>();
x.add(new SomeClass());
Iterator<SomeClass> i = x.iterator();
SomeClass z = i.next();

This allows the compiler to check your code at compile-time, but at runtime it still looks like the first example.

Method returning a "secureClient" (in a Java 7 environnement - NetBeans IDE and GlassFish Server: port https by default 3920 ), hope this could help :

I do it as follows in my php.ini:

error_reporting = E_ALL & ~E_WARNING  & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

This logs only fatal errors and no warnings.

Instead of counting up, you can also count down:

  nrToProcess = len(list)
  for s in list:
    s.doStuff()
    nrToProcess -= 1
    if nrToProcess==0:  # this is the last one
      s.doSpecialStuff()

I know it's pretty old question. but just for update.

Best way to use "SET NOCOUNT ON" is to put it up as a first statement in your SP and setting it OFF again just before the last SELECT statement.

mysqldump doesn't work with: >nul 2>&1
Instead use: 2> nul

This worked great for me. I had long links that would cause the table to exceed 100% on web browsers. Tested on IE, Chrome, Android and Safari.

And this seems to be a much more complete list, where I found some warnings specific to Android-Studio that I couldn't find elsewhere (e.g. SynchronizeOnNonFinalField)

https://jazzy.id.au/2008/10/30/list_of_suppresswarnings_arguments.html

Oh, now SO's guidelines contraddict SO's restrictions. On one hand, I am supposed to copy the list rather than providing only the link. But on the other hand, this would exceed the maximum allowed number of characters. So let's just hope the link won't break.

Sometimes Java generics just doesn't let you do what you want to, and you need to effectively tell the compiler that what you're doing really will be legal at execution time.

I usually find this a pain when I'm mocking a generic interface, but there are other examples too. It's usually worth trying to work out a way of avoiding the warning rather than suppressing it (the Java Generics FAQ helps here) but sometimes even if it is possible, it bends the code out of shape so much that suppressing the warning is neater. Always add an explanatory comment in that case!

The same generics FAQ has several sections on this topic, starting with "What is an "unchecked" warning?" - it's well worth a read.

The recommended IDisposable pattern is here. When programming a class that uses IDisposable, generally you should use two patterns:

When implementing a sealed class that doesn't use unmanaged resources, you simply implement a Dispose method as with normal interface implementations:

public sealed class A : IDisposable
{
    public void Dispose()
    {
        // get rid of managed resources, call Dispose on member variables...
    }
}

When implementing an unsealed class, do it like this:

public class B : IDisposable
{    
    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (disposing)
        {
            // get rid of managed resources
        }   
        // get rid of unmanaged resources
    }

    // only if you use unmanaged resources directly in B
    //~B()
    //{
    //    Dispose(false);
    //}
}

Notice that I haven't declared a finalizer in B; you should only implement a finalizer if you have actual unmanaged resources to dispose. The CLR deals with finalizable objects differently to non-finalizable objects, even if SuppressFinalize is called.

So, you shouldn't declare a finalizer unless you have to, but you give inheritors of your class a hook to call your Dispose and implement a finalizer themselves if they use unmanaged resources directly:

public class C : B
{
    private IntPtr m_Handle;

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            // get rid of managed resources
        }
        ReleaseHandle(m_Handle);

        base.Dispose(disposing);
    }

    ~C() {
        Dispose(false);
    }
}

If you're not using unmanaged resources directly (SafeHandle and friends doesn't count, as they declare their own finalizers), then don't implement a finalizer, as the GC deals with finalizable classes differently, even if you later suppress the finalizer. Also note that, even though B doesn't have a finalizer, it still calls SuppressFinalize to correctly deal with any subclasses that do implement a finalizer.

When a class implements the IDisposable interface, it means that somewhere there are some unmanaged resources that should be got rid of when you've finished using the class. The actual resources are encapsulated within the classes; you don't need to explicitly delete them. Simply calling Dispose() or wrapping the class in a using(...) {} will make sure any unmanaged resources are got rid of as necessary.

This should work:

$ mkdir -p dir

or:

if [[ ! -e $dir ]]; then
    mkdir $dir
elif [[ ! -d $dir ]]; then
    echo "$dir already exists but is not a directory" 1>&2
fi

which will create the directory if it doesn't exist, but warn you if the name of the directory you're trying to create is already in use by something other than a directory.

Using the newer version ''.format (also remember to specify how many digit after the . you wish to display, this depends on how small is the floating number). See this example:

>>> a = -7.1855143557448603e-17
>>> '{:f}'.format(a)
'-0.000000'

as shown above, default is 6 digits! This is not helpful for our case example, so instead we could use something like this:

>>> '{:.20f}'.format(a)
'-0.00000000000000007186'

Update

Starting in Python 3.6, this can be simplified with the new formatted string literal, as follows:

>>> f'{a:.20f}'
'-0.00000000000000007186'

An alternative that may fit in some situations is to assign the result of a command to a variable:

$ DUMMY=$( grep root /etc/passwd 2>&1 )
$ echo $?
0
$ DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
1

Since Bash and other POSIX commandline interpreters does not consider variable assignments as a command, the present command's return code is respected.

Note: assignement with the typeset or declare keyword is considered as a command, so the evaluated return code in case is the assignement itself and not the command executed in the sub-shell:

$ declare DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
0

Take this one, it's much faster than creating a new HashMap, if it's already one, but still secure, as each element is checked against it's type...

@SuppressWarnings("unchecked")
public static <K, V> HashMap<K, V> toHashMap(Object input, Class<K> key, Class<V> value) {
       assert input instanceof Map : input;

       for (Map.Entry<?, ?> e : ((HashMap<?, ?>) input).entrySet()) {
           assert key.isAssignableFrom(e.getKey().getClass()) : "Map contains invalid keys";
           assert value.isAssignableFrom(e.getValue().getClass()) : "Map contains invalid values";
       }

       if (input instanceof HashMap)
           return (HashMap<K, V>) input;
       return new HashMap<K, V>((Map<K, V>) input);
    }

SuppressFinalize should only be called by a class that has a finalizer. It's informing the Garbage Collector (GC) that this object was cleaned up fully.

The recommended IDisposable pattern when you have a finalizer is:

public class MyClass : IDisposable
{
    private bool disposed = false;

    protected virtual void Dispose(bool disposing)
    {
        if (!disposed)
        {
            if (disposing)
            {
                // called via myClass.Dispose(). 
                // OK to use any private object references
            }
            // Release unmanaged resources.
            // Set large fields to null.                
            disposed = true;
        }
    }

    public void Dispose() // Implement IDisposable
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    ~MyClass() // the finalizer
    {
        Dispose(false);
    }
}

Normally, the CLR keeps tabs on objects with a finalizer when they are created (making them more expensive to create). SuppressFinalize tells the GC that the object was cleaned up properly and doesn't need to go onto the finalizer queue. It looks like a C++ destructor, but doesn't act anything like one.

The SuppressFinalize optimization is not trivial, as your objects can live a long time waiting on the finalizer queue. Don't be tempted to call SuppressFinalize on other objects mind you. That's a serious defect waiting to happen.

Design guidelines inform us that a finalizer isn't necessary if your object implements IDisposable, but if you have a finalizer you should implement IDisposable to allow deterministic cleanup of your class.

Most of the time you should be able to get away with IDisposable to clean up resources. You should only need a finalizer when your object holds onto unmanaged resources and you need to guarantee those resources are cleaned up.

Note: Sometimes coders will add a finalizer to debug builds of their own IDisposable classes in order to test that code has disposed their IDisposable object properly.

public void Dispose() // Implement IDisposable
{
    Dispose(true);
#if DEBUG
    GC.SuppressFinalize(this);
#endif
}

#if DEBUG
~MyClass() // the finalizer
{
    Dispose(false);
}
#endif

Demo

You could try one of two things or a combination of both.

1. Be sure that your controller's name starts with a capital letter. eg "Mycontroller.php"
2. If you have not made any changes to your route, for some strange reason, you might have to include capital letters in your url. e.g if your controller is 'Mycontroller.php' with a function named 'testfunc' inside it, then your url will look like this: "http://www.yourdomain/index.php/Mycontroller/testfunc". Note the capital letter. (I'm assuming you haven't added the htaccess file to remove the 'index.php' part. If you have, just remove it from the url.)

Building on N.S's answer, I have a PowerShell script that exports to a CSV file with the quote marks around the field and comma separated and it skips the header information in the file.

add-pssnapin sqlserverprovidersnapin100
add-pssnapin sqlservercmdletsnapin100

$qry = @"
Select
  *
From
 tablename
"@

Invoke-Sqlcmd -ServerInstance Server -Database DBName -Query $qry | convertto-CSV -notype | select -skip 1  > "full path and filename.csv"

The first two lines enable the ability to use the Invoke-SqlCmd command-let.

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

What worked for me is to create a log4j properties file (you can find many examples over the net) and place it in properties folder in your project directory (create this folder if not exicts). The right click on the folder and Build Path->Use as Source Folder.

Hope it helps!

You still need to set callback in the params:

var params = {
  'a': b,
  'token_auth': TOKEN,
  'callback': 'functionName'
};
$sce.trustAsResourceUrl(url);

$http.jsonp(url, {
  params: params
});

Where 'functionName' is a stringified reference to globally defined function. You can define it outside of your angular script and then redefine it in your module.

I agree with micmdk.. I had a development environment setup with Push Notifications and needed a way to reset my phone to look like an initial install… and only these precise steps worked for me… requires TWO reboots of Device:

From APPLE TECH DOC:

Resetting the Push Notifications Permissions Alert on iOS The first time a push-enabled app registers for push notifications, iOS asks the user if they wish to receive notifications for that app. Once the user has responded to this alert it is not presented again unless the device is restored or the app has been uninstalled for at least a day.

If you want to simulate a first-time run of your app, you can leave the app uninstalled for a day. You can achieve the latter without actually waiting a day by following these steps:

1. Delete your app from the device.

2. Turn the device off completely and turn it back on.

3. Go to Settings > General > Date & Time and set the date ahead a day or more.

4. Turn the device off completely again and turn it back on.

I think you already listed the best practice and that is NOT to use it unless REALLY necessary. I would strongly recommend looking at your code in more detail, using profiling tools potentially if needed to answer these questions first.

1. Do you have something in your code that is declaring items at a larger scope than needed
2. Is the memory usage really too high
3. Compare performance before and after using GC.Collect() to see if it really helps.

The console is not available because the code is running in the cloud, not in your browser. Instead, use the Logger class provided by GAS:

Logger.log(playerArray[3])

and then view the results in the IDE under View > Logs...

Here's some documentation on logging with GAS.

Edit: 2017-07-20 Apps script now also provides Stackdriver Logging. View these logs in the script editor under View - Console Logs.

I assume the array i is ascend sorted, here is another solution with Iterator, it is more generic:

ArrayList<String> list = new ArrayList<String>();
list.add("A");
list.add("B");
list.add("C");
list.add("D");
list.add("E");
list.add("F");
list.add("G");
list.add("H");

int i[] = {1,3,5};

Iterator<String> itr = list.iterator();
int pos = 0;
int index = 0;
while( itr.hasNext() ){
    itr.next();
    if( pos >= i.length ){
        break;
    }
    if( i[pos] == index ){
        itr.remove();
        pos++;
    }

    index++;
}

Staying MVVM, I think using either Behaviors from the Blend SDK (System.Windows.Interactivity) or a custom interaction request from Prism could work really well for this sort of situation.

If going the Behavior route, here's the general idea:

public class CloseWindowBehavior : Behavior<Window>
{
    public bool CloseTrigger
    {
        get { return (bool)GetValue(CloseTriggerProperty); }
        set { SetValue(CloseTriggerProperty, value); }
    }

    public static readonly DependencyProperty CloseTriggerProperty =
        DependencyProperty.Register("CloseTrigger", typeof(bool), typeof(CloseWindowBehavior), new PropertyMetadata(false, OnCloseTriggerChanged));

    private static void OnCloseTriggerChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var behavior = d as CloseWindowBehavior;

        if (behavior != null)
        {
            behavior.OnCloseTriggerChanged();
        }
    }

    private void OnCloseTriggerChanged()
    {
        // when closetrigger is true, close the window
        if (this.CloseTrigger)
        {
            this.AssociatedObject.Close();
        }
    }
}

Then in your window, you would just bind the CloseTrigger to a boolean value that would be set when you wanted the window to close.

<Window x:Class="TestApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
        xmlns:local="clr-namespace:TestApp"
        Title="MainWindow" Height="350" Width="525">
    <i:Interaction.Behaviors>
        <local:CloseWindowBehavior CloseTrigger="{Binding CloseTrigger}" />
    </i:Interaction.Behaviors>

    <Grid>

    </Grid>
</Window>

Finally, your DataContext/ViewModel would have a property that you'd set when you wanted the window to close like this:

public class MainWindowViewModel : INotifyPropertyChanged
{
    private bool closeTrigger;

    /// <summary>
    /// Gets or Sets if the main window should be closed
    /// </summary>
    public bool CloseTrigger
    {
        get { return this.closeTrigger; }
        set
        {
            this.closeTrigger = value;
            RaisePropertyChanged(nameof(CloseTrigger));
        }
    }

    public MainWindowViewModel()
    {
        // just setting for example, close the window
        CloseTrigger = true;
    }

    protected void RaisePropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

(set your Window.DataContext = new MainWindowViewModel())

The OP needed to cast as string outside the {% set ... %}. But if that not your case you can do:

{% set curYear = 2013 | string() %}

Note that you need the parenthesis on that jinja filter.

If you're concatenating 2 variables, you can also use the ~ custom operator.

Old thread, but i wanted to update since i worked on this problem today, i didnt have jquery in my project so i did it the plain old javascript way, i also needed to block the content on the screen so in my xhtml

    <img id="loading" src="#{request.contextPath}/images/spinner.gif" style="display: none;"/>

in my javascript

    document.getElementsByClassName('myclass').style.opacity = '0.7'
    document.getElementById('loading').style.display = "block";

To display dialog box, you can use the following code. This is to display a simple AlertDialog box with multiple check boxes:

AlertDialog.Builder alertDialog= new AlertDialog.Builder(MainActivity.this); .
            alertDialog.setTitle("this is a dialog box ");
            alertDialog.setPositiveButton("ok", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(),"ok ive wrote this 'ok' here" ,Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.setNegativeButton("cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                        Toast.makeText(getBaseContext(), "cancel ' comment same as ok'", Toast.LENGTH_SHORT).show();


                }
            });
            alertDialog.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(), items[which] +(isChecked?"clicked'again i've wrrten this click'":"unchecked"),Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.show();

Heading

Whereas if you are using the showDialog function to display different dialog box or anything as per the arguments passed, you can create a self function and can call it under the onClickListener() function. Something like:

 public CharSequence[] items={"google","Apple","Kaye"};
public boolean[] checkedItems=new boolean[items.length];
Button bt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bt=(Button) findViewById(R.id.bt);
    bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            display(0);             
        }       
    });
}

and add the code of dialog box given above in the function definition.

This is more likely to get you what you want:

Scanner input = new Scanner(System.in);
String s = input.next();
System.out.println(s);

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

1. Open the file using vi myfile.csv
2. Press Escape
3. Type :%s/replaceme/withthis/
4. Type :wq and press Enter

Now you will have the new pattern in your file.

If, like me, you would just prefer people didn't click out to youtube using the logo, one option is to use a player like jwplayer. Using jwplayer the logo is still there just unclickable.

put it in between <pre></pre> tags then use this characters 	

it would not work without the <pre></pre> tags

You can try below code. Check http://api.jquery.com/jquery.grep/

var blockedTile = new Array("118", "67", "190", "43", "135", "520");
var searchNumber = "11878";
arr = jQuery.grep(blockedTile, function( i ) {
  return i === searchNumber;
});
if(arr.length){ console.log('Present'); }else{ console.log('Not Present'); }

check arr.length if it's more than 0 means string is present else it's not present.

I manged to set the MinDate & the MaxDate programmatically like this :

    final Calendar c = Calendar.getInstance();

    int maxYear = c.get(Calendar.YEAR) - 20; // this year ( 2011 ) - 20 = 1991
    int maxMonth = c.get(Calendar.MONTH);
    int maxDay = c.get(Calendar.DAY_OF_MONTH);

    int minYear = 1960;
    int minMonth = 0; // january
    int minDay = 25;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.create_account);
        BirthDateDP = (DatePicker) findViewById(R.id.create_account_BirthDate_DatePicker);
        BirthDateDP.init(maxYear - 10, maxMonth, maxDay, new OnDateChangedListener()
        {

        @Override
        public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            if (year < minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (monthOfYear < minMonth && year == minYear)
                view.updateDate(minYear, minMonth, minDay);

                if (dayOfMonth < minDay && year == minYear && monthOfYear == minMonth)
                view.updateDate(minYear, minMonth, minDay);


                if (year > maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (monthOfYear > maxMonth && year == maxYear)
                view.updateDate(maxYear, maxMonth, maxDay);

                if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
                view.updateDate(maxYear, maxMonth, maxDay);
        }}); // BirthDateDP.init()
    } // activity

it works fine for me, enjoy :)

I spent around 6 hours on the same issue today. Inserts go at a 'regular' speed (less than 3sec per 100K) up until to 5MI (out of total 30MI) rows and then the performance sinks drastically (all the way down to 1min per 100K).

I will not list all of the things that did not work and cut straight to the meat.

I dropped a primary key on the target table (which was a GUID) and my 30MI or rows happily flowed to their destination at a constant speed of less than 3sec per 100K.

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

The throws Exception declaration is an automated way of keeping track of methods that might throw an exception for anticipated but unavoidable reasons. The declaration is typically specific about the type or types of exceptions that may be thrown such as throws IOException or throws IOException, MyException.

We all have or will eventually write code that stops unexpectedly and reports an exception due to something we did not anticipate before running the program, like division by zero or index out of bounds. Since the errors were not expected by the method, they could not be "caught" and handled with a try catch clause. Any unsuspecting users of the method would also not know of this possibility and their programs would also stop.

When the programmer knows certain types of errors may occur but would like to handle these exceptions outside of the method, the method can "throw" one or more types of exceptions to the calling method instead of handling them. If the programmer did not declare that the method (might) throw an exception (or if Java did not have the ability to declare it), the compiler could not know and it would be up to the future user of the method to know about, catch and handle any exceptions the method might throw. Since programs can have many layers of methods written by many different programs, it becomes difficult (impossible) to keep track of which methods might throw exceptions.

Even though Java has the ability to declare exceptions, you can still write a new method with unhandled and undeclared exceptions, and Java will compile it and you can run it and hope for the best. What Java won't let you do is compile your new method if it uses a method that has been declared as throwing exception(s), unless you either handle the declared exception(s) in your method or declare your method as throwing the same exception(s) or if there are multiple exceptions, you can handle some and throw the rest.

When a programmer declares that the method throws a specific type of exception, it is just an automated way of warning other programmers using the method that an exception is possible. The programmer can then decide to handled the exception or pass on the warning by declaring the calling method as also throwing the same exception. Since the compiler has been warned the exception is possible in this new method, it can automatically check if future callers of the new method handle the exception or declare it and enforcing one or the other to happen.

The nice thing about this type of solution is that when the compiler reports Error: Unhandled exception type java.io.IOException it gives the file and line number of the method that was declared to throw the exception. You can then choose to simply pass the buck and declare your method also "throws IOException". This can be done all the way up to main method where it would then cause the program to stop and report the exception to the user. However, it is better to catch the exception and deal with it in a nice way such as explaining to the user what has happened and how to fix it. When a method does catch and handle the exception, it no longer has to declare the exception. The buck stops there so to speak.

use this following command:

git push -f origin master

random.choice([True, False])

would also work.

Here's the sample from the question modified to disable the button once clicked:

$(function() {
    $("#dialog").dialog({
        bgiframe: true,
        height: 'auto',
        width: 700,
        show: 'clip',
        hide: 'clip',
        modal: true,
        buttons: {
            'Add to request list': function(evt) {

                // get DOM element for button
                var buttonDomElement = evt.target;
                // Disable the button
                $(buttonDomElement).attr('disabled', true);

                $('form').submit();
            },
            'Cancel': function() {
                $(this).dialog('close');
            }
        }
    });
}

Also, the following question will also be helpful with this: How can I disable a button on a jQuery UI dialog?

For encoding to base64 in Angular2, you can use btoa() function.

Example:-

console.log(btoa("stringAngular2")); 
// Output:- c3RyaW5nQW5ndWxhcjI=

For decoding from base64 in Angular2, you can use atob() function.

Example:-

console.log(atob("c3RyaW5nQW5ndWxhcjI=")); 
// Output:- stringAngular2

If javacpl does not open and gives you Could not find the main class:, it could be that Java is confused because of changes in deployment.properties (can be found in C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment on Win7). Delete that file and everything's fine.

This bug seems to be 6 years old, cf. An app should be able to ignore properties that have become obsolete over time, shouldn't it?

Another good trick is to go into UTF8 mode in your editor so that you can actually see these funny characters and delete them yourself.

<input type="text" (keypress)="myMethod(myInput.value)" #myInput />

archive .ts

myMethod(value:string){
...
...
}

I used string to concatenate new object to an existing object.

private static void concatJSON() throws IOException, InterruptedException {

    JSONParser parser = new JSONParser();
    Object obj = parser.parse(new FileReader(new File(Main.class.getResource("/file/user.json").toURI())));


    JSONObject jsonObj = (JSONObject) obj; //usernameJsonObj

    String [] values = {"0.9" , Date.from(Calendar.getInstance().toInstant()).toLocaleString()},
            innermost = {"Accomplished", "LatestDate"}, 
            inner = {"Lesson1", "Lesson2", "Lesson3", "Lesson4"};
    String in = "Jayvee Villa";

    JSONObject jo1 = new JSONObject();
    for (int i = 0; i < innermost.length; i++)
        jo1.put(innermost[i], values[i]);

    JSONObject jo2 = new JSONObject();
    for (int i = 0; i < inner.length; i++)
        jo2.put(inner[i], jo1);

    JSONObject jo3 = new JSONObject();
    jo3.put(in, jo2);

    String merger = jsonObj.toString().substring(0, jsonObj.toString().length()-1) + "," +jo3.toString().substring(1);

    System.out.println(merger);
    FileWriter pr = new FileWriter(file);
    pr.write(merger);
    pr.flush();
    pr.close();
}

This will be the simplest way,

if (System.IO.File.Exists(filePath)) 
{
  System.IO.File.Delete(filePath);
  System.Threading.Thread.Sleep(20);
}

Thread.sleep will help to work perfectly, otherwise, it will affect the next step if we doing copy or write the file.

Another way I did is,

if (System.IO.File.Exists(filePath))
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
System.IO.File.Delete(filePath);
}

I realize this is a little old, but, yes it can be done. Some javascript to get you started:

viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');

Just change the parts you need and Mobile Safari will respect the new settings.

Update:

If you don't already have the meta viewport tag in the source, you can append it directly with something like this:

var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);

Or if you're using jQuery:

$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');

This has the added benefit of being able to sort ascending or descending, using Java 8

import static java.util.Comparator.comparingInt;
import static java.util.stream.Collectors.toMap;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Map.Entry;
import java.util.stream.Collectors;
import java.util.stream.Stream;

class Utils {
    public static Map<String, Integer> sortMapBasedOnValues(Map<String, Integer> map, boolean descending) {
        int multiplyBy = (descending) ? -1: 1;
        Map<String, Integer> sorted =  map.entrySet().stream()
                .sorted(comparingInt(e -> multiplyBy * e.getValue() ))
                .collect(toMap(
                        Map.Entry::getKey, 
                        Map.Entry::getValue,
                        (a, b) -> { throw new AssertionError();},
                        LinkedHashMap::new
                    ));
        return sorted;
    }
}

SELECT sc.name +'.'+ ta.name TableName

API Documentation

According to the Android developers guide for android.hardware.Camera, they state:

We recommend using the new android.hardware.camera2 API for new applications.

On the information page about android.hardware.camera2, (linked above), it is stated:

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.

The problem

When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.

For example getting camera orientation on android.hardware.camera

@Override
public int getOrientation(final int cameraId) {
    Camera.CameraInfo info = new Camera.CameraInfo();
    Camera.getCameraInfo(cameraId, info);
    return info.orientation;
}

Versus android.hardware.camera2

@Override
public int getOrientation(final int cameraId) {
    try {
        CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        String[] cameraIds = manager.getCameraIdList();
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
        return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
    } catch (CameraAccessException e) {
        // TODO handle error properly or pass it on
        return 0;
    }
}

This makes it hard to switch from one to another and write code that can handle both implementations.

Note that in this single code example I already had to work around the fact that the olde camera API works with int primitives for camera IDs while the new one works with String objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.

One away around

Now to work around this huge difference you can implement an interface first and reference that interface in your code.

Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.

In the next section I'll quickly explain how to load one or another.

The interface wrapping all you need, to limit this example I only have 2 methods here.

public interface CameraSupport {
    CameraSupport open(int cameraId);
    int getOrientation(int cameraId);
}

Now have a class for the old camera hardware api:

@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {

    private Camera camera;

    @Override
    public CameraSupport open(final int cameraId) {
        this.camera = Camera.open(cameraId);
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
       Camera.CameraInfo info = new Camera.CameraInfo();
       Camera.getCameraInfo(cameraId, info);
       return info.orientation;
    }
}

And another one for the new hardware api:

public class CameraNew implements CameraSupport {

    private CameraDevice camera;
    private CameraManager manager;

    public CameraNew(final Context context) {
        this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
    }

    @Override

Loading the proper API

Now to load either your CameraOld or CameraNew class you'll have to check the API level since CameraNew is only available from api level 21.

If you have dependency injection set up already you can do so in your module when providing the CameraSupport implementation. Example:

@Module public class CameraModule {

    @Provides
    CameraSupport provideCameraSupport(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            return new CameraNew(context);
        } else {
            return new CameraOld();
        }
    } 
}

If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.

Use the Mod % (modulus) operator

if ($x % 6 == 0) return 1;


function nearest_multiple_of_6($x) {
    if ($x % 6 == 0) return $x;    

    return (($x / 6) + 1) * 6;
}

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

<!DOCTYPE html>

<script>

// stores the device context of the canvas we use to draw the outlines
// initialized in myInit, used in myHover and myLeave
var hdc;

// shorthand func

// takes a string that contains coords eg - "227,307,261,309, 339,354, 328,371, 240,331"
// draws a line from each co-ord pair to the next - assumes starting point needs to be repeated as ending point.
function drawPoly(coOrdStr)
{
    var mCoords = coOrdStr.split(',');
    var i, n;
    n = mCoords.length;

    hdc.beginPath();
    hdc.moveTo(mCoords[0], mCoords[1]);
    for (i=2; i<n; i+=2)
    {
        hdc.lineTo(mCoords[i], mCoords[i+1]);
    }
    hdc.lineTo(mCoords[0], mCoords[1]);
    hdc.stroke();
}

function drawRect(coOrdStr)
{
    var mCoords = coOrdStr.split(',');
    var top, left, bot, right;

    top = mCoords[1];
    right = mCoords[2];
    bot = mCoords[3];
    hdc.strokeRect(left,top,right-left,bot-top); 
}

function myHover(element)
{
    var hoveredElement = element;
    var coordStr = element.getAttribute('coords');
    var areaType = element.getAttribute('shape');

    switch (areaType)
    {
        case 'polygon':

    }

function myLeave()

    var canvas = byId('myCanvas');
    hdc.clearRect(0, 0, canvas.width, canvas.height);
}

function myInit()
{
    // get the target image
    var img = byId('img-imgmap201293016112');

    var x,y, w,h;

    // get it's position and width+height
    x = img.offsetLeft;
    y = img.offsetTop;
    w = img.clientWidth;
    h = img.clientHeight;

    // move the canvas, so it's contained by the same parent as the image
    var imgParent = img.parentNode;
    var can = byId('myCanvas');
    imgParent.appendChild(can);

    // place the canvas in front of the image
    can.style.zIndex = 1;

    // position it over the image
    can.style.left = x+'px';
    can.style.top = y+'px';

    // make same size as the image
    can.setAttribute('width', w+'px');
    can.setAttribute('height', h+'px');

In my case only removing org.eclipse.e4.workbench directory (under .metadata/.plugins) and restarting Eclipse solved the problem.

In Node.js, you can use util.inspect(object). It automatically replaces circular links with "[Circular]".

Albeit being built-in (no installation is required), you must import it

import * as util from 'util' // has no default export
import { inspect } from 'util' // or directly
// or 
var util = require('util')

console.log(util.inspect(myObject))

Also be aware that you can pass options object to inspect (see link above)

inspect(myObject[, options: {showHidden, depth, colors, showProxy, ...moreOptions}])

Please, read and give kudos to commenters below...

As the error states - the database is not open - it was previously shut down, and someone left it in the middle of the startup process. They may either be intentional, or unintentional (i.e., it was supposed to be open, but failed to do so).

Assuming that's nothing wrong with the database itself, you could open it with a simple statement:(Since the question is asked specifically in the context of SQLPlus, kindly remember to put a statement terminator(Semicolon) at the end mandatorily, otherwise, it will result in an error.)

Bigtable

A Distributed Storage System for Structured Data

Bigtable is a distributed storage system (built by Google) for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers.

Many projects at Google store data in Bigtable, including web indexing, Google Earth, and Google Finance. These applications place very different demands on Bigtable, both in terms of data size (from URLs to web pages to satellite imagery) and latency requirements (from backend bulk processing to real-time data serving).

Despite these varied demands, Bigtable has successfully provided a flexible, high-performance solution for all of these Google products.

Some features

• fast and extremely large-scale DBMS
• a sparse, distributed multi-dimensional sorted map, sharing characteristics of both row-oriented and column-oriented databases.
• designed to scale into the petabyte range
• it works across hundreds or thousands of machines
• it is easy to add more machines to the system and automatically start taking advantage of those resources without any reconfiguration
• each table has multiple dimensions (one of which is a field for time, allowing versioning)
• tables are optimized for GFS (Google File System) by being split into multiple tablets - segments of the table as split along a row chosen such that the tablet will be ~200 megabytes in size.

Architecture

BigTable is not a relational database. It does not support joins nor does it support rich SQL-like queries. Each table is a multidimensional sparse map. Tables consist of rows and columns, and each cell has a time stamp. There can be multiple versions of a cell with different time stamps. The time stamp allows for operations such as "select 'n' versions of this Web page" or "delete cells that are older than a specific date/time."

In order to manage the huge tables, Bigtable splits tables at row boundaries and saves them as tablets. A tablet is around 200 MB, and each machine saves about 100 tablets. This setup allows tablets from a single table to be spread among many servers. It also allows for fine-grained load balancing. If one table is receiving many queries, it can shed other tablets or move the busy table to another machine that is not so busy. Also, if a machine goes down, a tablet may be spread across many other servers so that the performance impact on any given machine is minimal.

Tables are stored as immutable SSTables and a tail of logs (one log per machine). When a machine runs out of system memory, it compresses some tablets using Google proprietary compression techniques (BMDiff and Zippy). Minor compactions involve only a few tablets, while major compactions involve the whole table system and recover hard-disk space.

The locations of Bigtable tablets are stored in cells. The lookup of any particular tablet is handled by a three-tiered system. The clients get a point to a META0 table, of which there is only one. The META0 table keeps track of many META1 tablets that contain the locations of the tablets being looked up. Both META0 and META1 make heavy use of pre-fetching and caching to minimize bottlenecks in the system.

Implementation

BigTable is built on Google File System (GFS), which is used as a backing store for log and data files. GFS provides reliable storage for SSTables, a Google-proprietary file format used to persist table data.

Another service that BigTable makes heavy use of is Chubby, a highly-available, reliable distributed lock service. Chubby allows clients to take a lock, possibly associating it with some metadata, which it can renew by sending keep alive messages back to Chubby. The locks are stored in a filesystem-like hierarchical naming structure.

There are three primary server types of interest in the Bigtable system:

1. Master servers: assign tablets to tablet servers, keeps track of where tablets are located and redistributes tasks as needed.
2. Tablet servers: handle read/write requests for tablets and split tablets when they exceed size limits (usually 100MB - 200MB). If a tablet server fails, then a 100 tablet servers each pickup 1 new tablet and the system recovers.
3. Lock servers: instances of the Chubby distributed lock service. Lots of actions within BigTable require acquisition of locks including opening tablets for writing, ensuring that there is no more than one active Master at a time, and access control checking.

Example from Google's research paper:

A slice of an example table that stores Web pages. The row name is a reversed URL. The contents column family contains the page contents, and the anchor column family contains the text of any anchors that reference the page. CNN's home page is referenced by both the Sports Illustrated and the MY-look home pages, so the row contains columns named anchor:cnnsi.com and anchor:my.look.ca. Each anchor cell has one version; the contents column has three versions, at timestamps t3, t5, and t6.

API

Typical operations to BigTable are creation and deletion of tables and column families, writing data and deleting columns from a row. BigTable provides this functions to application developers in an API. Transactions are supported at the row level, but not across several row keys.

Here is the link to the PDF of the research paper.

And here you can find a video showing Google's Jeff Dean in a lecture at the University of Washington, discussing the Bigtable content storage system used in Google's backend.

as suggested, you can use 'die and dump' such as

dd($var)

or only 'dump', without dying,

dump($var)

<iframe>

The iframe element represents a nested browsing context. HTML 5 standard - "The <iframe> element"

Primarily used to include resources from other domains or subdomains but can be used to include content from the same domain as well. The <iframe>'s strength is that the embedded code is 'live' and can communicate with the parent document.

<embed>

Standardised in HTML 5, before that it was a non standard tag, which admittedly was implemented by all major browsers. Behaviour prior to HTML 5 can vary ...

The embed element provides an integration point for an external (typically non-HTML) application or interactive content. (HTML 5 standard - "The <embed> element")

Used to embed content for browser plugins. Exceptions to this is SVG and HTML that are handled differently according to the standard.

The details of what can and can not be done with the embedded content is up to the browser plugin in question. But for SVG you can access the embedded SVG document from the parent with something like:

svg = document.getElementById("parent_id").getSVGDocument();

From inside an embedded SVG or HTML document you can reach the parent with:

parent = window.parent.document;

For embedded HTML there is no way to get at the embedded document from the parent (that I have found).

<object>

The <object> element can represent an external resource, which, depending on the type of the resource, will either be treated as an image, as a nested browsing context, or as an external resource to be processed by a plugin. (HTML 5 standard - "The <object> element")

Conclusion

Unless you are embedding SVG or something static you are probably best of using <iframe>. To include SVG use <embed> (if I remember correctly <object> won't let you script†). Honestly I don't know why you would use <object> unless for older browsers or flash (that I don't work with).

† As pointed out in the comments below; scripts in <object> will run but the parent and child contexts can't communicate directly. With <embed> you can get the context of the child from the parent and vice versa. This means they you can use scripts in the parent to manipulate the child etc. That part is not possible with <object> or <iframe> where you would have to set up some other mechanism instead, such as the JavaScript postMessage API.

Tired of sys.path hacks?

There are plenty of sys.path.append -hacks available, but I found an alternative way of solving the problem in hand.

Summary

• Wrap the code into one folder (e.g. packaged_stuff)
• Create setup.py script where you use setuptools.setup(). (see minimal setup.py below)
• Pip install the package in editable state with pip install -e <myproject_folder>
• Import using from packaged_stuff.modulename import function_name

Setup

The starting point is the file structure you have provided, wrapped in a folder called myproject.

.
+-- myproject
    +-- api
    ¦   +-- api_key.py
    ¦   +-- api.py
    ¦   +-- __init__.py
    +-- examples
    ¦   +-- example_one.py
    ¦   +-- example_two.py
    ¦   +-- __init__.py
    +-- LICENCE.md
    +-- README.md
    +-- tests
        +-- __init__.py
        +-- test_one.py

I will call the . the root folder, and in my example case it is located at C:\tmp\test_imports\.

api.py

As a test case, let's use the following ./api/api.py

def function_from_api():
    return 'I am the return value from api.api!'

test_one.py

from api.api import function_from_api

def test_function():
    print(function_from_api())

if __name__ == '__main__':
    test_function()

Try to run test_one:

PS C:\tmp\test_imports> python .\myproject\tests\test_one.py
Traceback (most recent call last):
  File ".\myproject\tests\test_one.py", line 1, in <module>
    from api.api import function_from_api
ModuleNotFoundError: No module named 'api'

Also trying relative imports wont work:

Using from ..api.api import function_from_api would result into

PS C:\tmp\test_imports> python .\myproject\tests\test_one.py
Traceback (most recent call last):
  File ".\tests\test_one.py", line 1, in <module>
    from ..api.api import function_from_api
ValueError: attempted relative import beyond top-level package

Steps

1. Make a setup.py file to the root level directory

The contents for the setup.py would be*

from setuptools import setup, find_packages

setup(name='myproject', version='1.0', packages=find_packages())

2. Use a virtual environment

If you are familiar with virtual environments, activate one, and skip to the next step. Usage of virtual environments are not absolutely required, but they will really help you out in the long run (when you have more than 1 project ongoing..). The most basic steps are (run in the root folder)

• Create virtual env
  • python -m venv venv
• Activate virtual env
  • source ./venv/bin/activate (Linux, macOS) or ./venv/Scripts/activate (Win)

To learn more about this, just Google out "python virtual env tutorial" or similar. You probably never need any other commands than creating, activating and deactivating.

Once you have made and activated a virtual environment, your console should give the name of the virtual environment in parenthesis

PS C:\tmp\test_imports> python -m venv venv
PS C:\tmp\test_imports> .\venv\Scripts\activate
(venv) PS C:\tmp\test_imports>

and your folder tree should look like this**

.
+-- myproject
¦   +-- api
¦   ¦   +-- api_key.py
¦   ¦   +-- api.py
¦   ¦   +-- __init__.py
¦   +-- examples
¦   ¦   +-- example_one.py
¦   ¦   +-- example_two.py
¦   ¦   +-- __init__.py
¦   +-- LICENCE.md
¦   +-- README.md
¦   +-- tests
¦       +-- __init__.py
¦       +-- test_one.py
+-- setup.py
+-- venv
    +-- Include
    +-- Lib
    +-- pyvenv.cfg
    +-- Scripts [87 entries exceeds filelimit, not opening dir]

3. pip install your project in editable state

Install your top level package myproject using pip. The trick is to use the -e flag when doing the install. This way it is installed in an editable state, and all the edits made to the .py files will be automatically included in the installed package.

In the root directory, run

pip install -e . (note the dot, it stands for "current directory")

You can also see that it is installed by using pip freeze

(venv) PS C:\tmp\test_imports> pip install -e .
Obtaining file:///C:/tmp/test_imports
Installing collected packages: myproject
  Running setup.py develop for myproject
Successfully installed myproject
(venv) PS C:\tmp\test_imports> pip freeze
myproject==1.0

4. Add myproject. into your imports

Note that you will have to add myproject. only into imports that would not work otherwise. Imports that worked without the setup.py & pip install will work still work fine. See an example below.

Test the solution

Now, let's test the solution using api.py defined above, and test_one.py defined below.

test_one.py

from myproject.api.api import function_from_api

def test_function():
    print(function_from_api())

if __name__ == '__main__':
    test_function()

running the test

(venv) PS C:\tmp\test_imports> python .\myproject\tests\test_one.py
I am the return value from api.api!

* See the setuptools docs for more verbose setup.py examples.

** In reality, you could put your virtual environment anywhere on your hard disk.

SyntaxError: non-default argument follows default argument

If you were to allow this, the default arguments would be rendered useless because you would never be able to use their default values, since the non-default arguments come after.

In Python 3 however, you may do the following:

def fun1(a="who is you", b="True", *, x, y):
    pass

which makes x and y keyword only so you can do this:

fun1(x=2, y=2)

This works because there is no longer any ambiguity. Note you still can't do fun1(2, 2) (that would set the default arguments).

The simplest way that doesn't require third party libraries it to create a URL object and then call either openConnection or openStream on it. Note that this is a pretty basic API, so you won't have a lot of control over the headers.

I know it's too late, but with API 2.0 you can do

from command line with:

curl https://api.bitbucket.org/2.0/repositories/<user>/<repo>/filehistory/<branch>/<path_file>

or in php with:

$data = json_decode(file_get_contents("https://api.bitbucket.org/2.0/repositories/<user>/<repo>/filehistory/<branch>/<path_file>", true));

then you have the history of your file (from the most recent commit to the oldest one):

{
"pagelen": 50,
"values": [
    {
      "links": {
        "self": {
          "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/src/<hash>/<path_file>"
        },
        "meta": {
          "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/src/<HEAD>/<path_file>?format=meta"
        },
        "history": {

          },
          "html": {
            "href": "https://bitbucket.org/<user>/<repo>/commits/<HEAD>"
          }
        }
      },
      "attributes": [],
      "path": "<path_file>",
      "type": "commit_file",
      "size": 31
    },
    {
      "links": {
        "self": {
          "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/src/<HEAD~1>/<path_file>"
        },
        "meta": {
          "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/src/<HEAD~1>/<path_file>?format=meta"
        },
        "history": {
          "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/filehistory/<HEAD~1>/<path_file>"
        }
      },
      "commit": {
        "hash": "<HEAD~1>",
        "type": "commit",
        "links": {
          "self": {
            "href": "https://api.bitbucket.org/2.0/repositories/<user>/<repo>/commit/<HEAD~1>"
          },
          "html": {
            "href": "https://bitbucket.org/<user>/<repo>/commits/<HEAD~1>"
          }
        }
      },
      "attributes": [],
      "path": "<path_file>",
      "type": "commit_file",
      "size": 20
    }
  ],
  "page": 1
}

where values > links > self provides the file at the moment in the history which you can retrieve it with curl <link> or file_get_contents(<link>).

Eventually, from the command line you can filter with:

 curl https://api.bitbucket.org/2.0/repositories/<user>/<repo>/filehistory/<branch>/<path_file>?fields=values.links.self

in php, just make a foreach loop on the array $data.

Note: if <path_file> has a / you have to convert it in %2F.

See the doc here: https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/%7Busername%7D/%7Brepo_slug%7D/filehistory/%7Bnode%7D/%7Bpath%7D

I think that doing this might be easier than most people think!

Try this:

var yourTextArea = document.getElementById("usertext").value;
// In case you want to limit the number of characters in no less than, say, 10
// or no more than 400.        
    if (yourTextArea.length < 10 || yourTextArea.length > 400) {
        alert("The field must have no less than 10 and no more than 400 characters.");
        return false;
    }

Please let me know it this was useful. And if so, vote up! Thx!

The $('#dialog').parent().appendTo($("form:first")) solution works fine in IE 9. But in IE 8 it makes the dialog appear and disappear directly. You can't see this unless you place some alerts so it seems that the dialog never appears. I spend one morning finding a solution that works on both versions and the only solution that works on both versions 8 and 9 is:

$(".ui-dialog").prependTo("form");

Hope this helps others that are struggeling with the same issue

To close a windows form (System.Windows.Forms.Form) when one of its button is clicked: in Visual Studio, open the form in the designer, right click on the button and open its property page, then select the field DialogResult an set it to OK or the appropriate value.

Try the following code. The value you are looking for is stored on a GuidAttribute instance attached to the Assembly

using System.Runtime.InteropServices;

static void Main(string[] args)
{
    var assembly = typeof(Program).Assembly;
    var attribute = (GuidAttribute)assembly.GetCustomAttributes(typeof(GuidAttribute),true)[0];
    var id = attribute.Value;
    Console.WriteLine(id);
}

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

The main problem is that operator [] is used to insert and read a value into and from the map, so it cannot be const. If the key does not exist, it will create a new entry with a default value in it, incrementing the size of the map, that will contain a new key with an empty string ,in this particular case, as a value if the key does not exist yet. You should avoid operator[] when reading from a map and use, as was mention before, "map.at(key)" to ensure bound checking. This is one of the most common mistakes people often do with maps. You should use "insert" and "at" unless your code is aware of this fact. Check this talk about common bugs Curiously Recurring C++ Bugs at Facebook

Caller-saved registers (AKA volatile registers, or call-clobbered) are used to hold temporary quantities that need not be preserved across calls.

For that reason, it is the caller's responsibility to push these registers onto the stack or copy them somewhere else if it wants to restore this value after a procedure call.

It's normal to let a call destroy temporary values in these registers, though.

Callee-saved registers (AKA non-volatile registers, or call-preserved) are used to hold long-lived values that should be preserved across calls.

When the caller makes a procedure call, it can expect that those registers will hold the same value after the callee returns, making it the responsibility of the callee to save them and restore them before returning to the caller. Or to not touch them.

It means the text is stored as wchar_t characters rather than plain old char characters.

(I originally said it meant unicode. I was wrong about that. But it can be used for unicode.)

Accessing localhost from the iPhone will simply do a loopback / try to connect to itself (If it supports that?).

What you need to do is find the IP of your desktop machine (e.g. If Windows, go to the Command Prompt and type ipconfig or go to Network and Sharing Centre and look up connection status.

Once you have your ip, simply visit that from your browser e.g. http://192.168.0.102.

You may need to open up port 80 (or whatever port your website is running on) in the inbound security of your firewall if you are running one.

Note: don't forget the app's port if what you want is to debug the app in your iPhone's browser like: http://192.168.0.102:3000. In this example 3000 is the default port used by ReactJS.

Google Chrome does not allow to load local resources because of the security. Chrome need http url. Internet Explorer and Edge allows to load local resources, but Safari, Chrome, and Firefox doesn't allows to load local resources.

Go to file location and start the Python Server from there.

python -m SimpleHttpServer

then put that url into function:

function run(){
var URL = "http://172.271.1.20:8000/" /* http://0.0.0.0:8000/ or http://127.0.0.1:8000/; */

An artifact is a JAR or something that you store in a repository. Maven gets them out and builds your code.

It is also possible to use this:

var user_name = document.forms[0].elements[0];
var user_email = document.forms[0].elements[1];
var user_message = document.forms[0].elements[2];

All the elements of forms are stored in an array by Javascript. This takes the elements from the first form and stores each value into a unique variable.

This is what I did:

yourEditText.setCursorVisible(false); //This code is used when you do not want the cursor to be visible at startup
        yourEditText.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                v.onTouchEvent(event);   // handle the event first
                InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm != null) {

                    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);  // hide the soft keyboard
                    yourEditText.setCursorVisible(true); //This is to display cursor when upon onTouch of Edittext
                }
                return true;
            }
        });

They are useful if you are (for some reason) using column names with certain characters for example.

Select First Name From People

would not work, but putting square brackets around the column name would work

Select [First Name] From People

In short, it's a way of explicitly declaring a object name; column, table, database, user or server.

If your Objects are containing of Strings only, then you can do it like this:

Map<String,Object> map = new HashMap<String,Object>(); //Object is containing String
Map<String,String> newMap =new HashMap<String,String>();
for (Map.Entry<String, Object> entry : map.entrySet()) {
       if(entry.getValue() instanceof String){
            newMap.put(entry.getKey(), (String) entry.getValue());
          }
 }

If every Objects are not String then you can replace (String) entry.getValue() into entry.getValue().toString().

I believe you need to map the result before you subscribe to it. You configure it like this:

  updateProfileInformation(user: User) {
    var headers = new Headers();
    headers.append('Content-Type', this.constants.jsonContentType);

    var t = localStorage.getItem("accessToken");
    headers.append("Authorization", "Bearer " + t;
    var body = JSON.stringify(user);

    return this.http.post(this.constants.userUrl + "UpdateUser", body, { headers: headers })
      .map((response: Response) => {
        var result = response.json();
        return result;
      })

I assume that you have some sort of List component and some sort of Item component. The way I did it in one project was to let the item know if it was active or not; the item would ask the list to scroll it into view if necessary. Consider the following pseudocode:

class List extends React.Component {
  render() {
    return <div>{this.props.items.map(this.renderItem)}</div>;
  }

  renderItem(item) {
    return <Item key={item.id} item={item}
                 active={item.id === this.props.activeId}
                 scrollIntoView={this.scrollElementIntoViewIfNeeded} />
  }

  scrollElementIntoViewIfNeeded(domNode) {
    var containerDomNode = React.findDOMNode(this);
    // Determine if `domNode` fully fits inside `containerDomNode`.
    // If not, set the container's scrollTop appropriately.
  }
}

class Item extends React.Component {
  render() {
    return <div>something...</div>;
  }

  componentDidMount() {
    this.ensureVisible();
  }

  componentDidUpdate() {
    this.ensureVisible();
  }

  ensureVisible() {
    if (this.props.active) {
      this.props.scrollIntoView(React.findDOMNode(this));
    }
  }
}

A better solution is probably to make the list responsible for scrolling the item into view (without the item being aware that it's even in a list). To do so, you could add a ref attribute to a certain item and find it with that:

class List extends React.Component {
  render() {
    return <div>{this.props.items.map(this.renderItem)}</div>;
  }

  renderItem(item) {
    var active = item.id === this.props.activeId;
    var props = {
      key: item.id,
      item: item,
      active: active
    };
    if (active) {
      props.ref = "activeItem";
    }
    return <Item {...props} />
  }

  componentDidUpdate(prevProps) {
    // only scroll into view if the active item changed last render
    if (this.props.activeId !== prevProps.activeId) {
      this.ensureActiveItemVisible();
    }
  }

  ensureActiveItemVisible() {
    var itemComponent = this.refs.activeItem;
    if (itemComponent) {
      var domNode = React.findDOMNode(itemComponent);
      this.scrollElementIntoViewIfNeeded(domNode);
    }
  }

  scrollElementIntoViewIfNeeded(domNode) {
    var containerDomNode = React.findDOMNode(this);
    // Determine if `domNode` fully fits inside `containerDomNode`.
    // If not, set the container's scrollTop appropriately.
  }
}

If you don't want to do the math to determine if the item is visible inside the list node, you could use the DOM method scrollIntoView() or the Webkit-specific scrollIntoViewIfNeeded, which has a polyfill available so you can use it in non-Webkit browsers.

I answered a similar question here

As @Syden said, the mixins will work. Another option is using SASS map-get like this..

@media (min-width: map-get($grid-breakpoints, sm)){
  .something {
    padding: 10px;
   }
}

@media (min-width: map-get($grid-breakpoints, md)){
  .something {
    padding: 20px;
   }
}

No, it's seriously not worth changing. The sort of improvements you're going to get when fiddling with micro-optimisations like this will not be worth it. Even the method call cost will be removed if the min function is called enough.

If you have a problem with your algorithm, your best bet is to look into macro-optimisations ("big picture" stuff like algorithm selection or tuning) - you'll generally get much better performance improvements there.

And your comment that removing Math.pow gave improvements may well be correct but that's because it's a relatively expensive operation. Math.min will not even be close to that in terms of cost.

You can use a CSS3 transition for this. Have a look at this example:

http://jsfiddle.net/ujDkf/1/

Here is the main code:

#box {
  position : relative;
  width : 100px;
  height : 100px;
  background-color : gray;
  border : 5px solid black;
  -webkit-transition : border 500ms ease-out;
  -moz-transition : border 500ms ease-out;
  -o-transition : border 500ms ease-out;
  transition : border 500ms ease-out;
}

#box:hover {
   border : 10px solid red;   
}

For centos7 I required: sudo yum install mysql-devel gcc python-pip python-devel sudo pip install mysql-python

So, gcc and mysql-devel (rather than mysql) were important

This is working for linux and windows as well with standard library

paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c',
         'a/b/../../a/b/c/', 'a/b/../../a/b/c']

def path_leaf(path):
    return path.strip('/').strip('\\').split('/')[-1].split('\\')[-1]

[path_leaf(path) for path in paths]

Results:

['c', 'c', 'c', 'c', 'c', 'c', 'c']

Try the following line:

while read line1; do read line2; echo "$line1 $line2"; done <old.txt>new_file

Put delimiter in-between

"$line1 $line2";

e.g. if the delimiter is |, then:

"$line1|$line2";

Combine Mixin with Extend

I just stumbled upon a combination of Mixin and Extend:

reused blocks:

.block1 { box-shadow: 0 5px 10px #000; }

.block2 { box-shadow: 5px 0 10px #000; }

.block3 { box-shadow: 0 0 1px #000; }

dynamic mixin:

@mixin customExtend($class){ @extend .#{$class}; }

use mixin:

like: @include customExtend(block1);

h1 {color: fff; @include customExtend(block2);}

Sass will compile only the mixins content to the extended blocks, which makes it able to combine blocks without generating duplicate code. The Extend logic only puts the classname of the Mixin import location in the block1, ..., ... {box-shadow: 0 5px 10px #000;}

Right-click, then "Open link in new tab"

edit : you can also double-click, it has the same effect

I had an issue using this in a user control (in a page this worked fine); the Button1 is inside an updatepanel, and the scriptmanager is on the usercontrol.

protected void Button1_Click(object sender, EventArgs e)  
{  
    string scriptstring = "alert('Welcome');";  
    ScriptManager.RegisterStartupScript(this, this.GetType(), "alertscript", scriptstring, true);  
}

Now it seems you have to be careful with the first two arguments, they need to reference your page, not your control

ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "alertscript", scriptstring, true);

That's a side-effect of a feature called optimistic concurrency.

Not 100% sure how to turn it on/off in Entity Framework but basically what it's telling you is that between when you grabbed the data out of the database and when you saved your changes someone else has changed the data (Which meant when you went to save it 0 rows actually got updated). In SQL terms, their update query's where clause contains the original value of every field in the row, and if 0 rows are affected it knows something's gone wrong.

The idea behind it is that you won't end up overwriting a change that your application didn't know has happened - it's basically a little safety measure thrown in by .NET on all your updates.

If it's consistent, odds are it's happening within your own logic (EG: You're actually updating the data yourself in another method in-between the select and the update), but it could be simply a race condition between two applications.

folks, I got this Bootstrap dropdown working. I modified the click event slightly in order to keep the currently-selected image. And as you see, the USD currency is the default selected :

<div class="btn-group" style="margin:10px;">    <!-- CURRENCY, BOOTSTRAP DROPDOWN -->
                <!--<a class="btn btn-primary" href="javascript:void(0);">Currency</a>-->                    
                <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
                <ul class="dropdown-menu">
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-aud-small.png" /> AUD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cad-small.png" /> CAD</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-cny-small.png" /> CNY</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-gbp-small.png" /> GBP</a>
                    </li>
                    <li><a href="javascript:void(0);">
                        <img src="../../Images/flag-usd-small.png" /> USD</a>

                </ul>
            </div>


/* BOOTSTRAP DROPDOWN MENU - Update selected item text and image */
$(".dropdown-menu li a").click(function () {
    var selText = $(this).text();
    var imgSource = $(this).find('img').attr('src');
    var img = '<img src="' + imgSource + '"/>';        
    $(this).parents('.btn-group').find('.dropdown-toggle').html(img + ' ' + selText + ' <span class="caret"></span>');
});

I think you are missing using System.Linq; from this system class.

and also add using System.Data.Entity; to the code

You can use jquery's load function here.

$("#your_element_id").load("file_name.html");

If you need more info, here is the link.

More actual solution:

<a id="someId">Link</a>

const a = document.querySelector('#someId');
a.href = 'url';

Everyone else's method doesn't account for whitespaces. Obviously nobody really considers a whitespace a special character.

Use this method to detect special characters not including whitespaces:

import re

def detect_special_characer(pass_string): 
  regex= re.compile('[@_!#$%^&*()<>?/\|}{~:]') 
  if(regex.search(pass_string) == None): 
    res = False
  else: 
    res = True
  return(res)

I have streamlined the answer of @Quirliom above into functions that can be used:

private static boolean hasLength(CharSequence data) {
    if (String.valueOf(data).length() >= 8) return true;
    else return false;
}

private static boolean hasSymbol(CharSequence data) {
    String password = String.valueOf(data);
    boolean hasSpecial = !password.matches("[A-Za-z0-9 ]*");
    return hasSpecial;
}

private static boolean hasUpperCase(CharSequence data) {
    String password = String.valueOf(data);
    boolean hasUppercase = !password.equals(password.toLowerCase());
    return hasUppercase;
}

private static boolean hasLowerCase(CharSequence data) {
    String password = String.valueOf(data);
    boolean hasLowercase = !password.equals(password.toUpperCase());
    return hasLowercase;
}

don't uninstall anything. a system with multiple versions of java works just fine. and you don't need to update your environment varables (e.g. java_home, path, etc..).

yes, ireports 3.6.1 needs java 7 (doesn't work with java 8).

all you have to do is edit C:\Program Files\Jaspersoft\iReport-nb-3.6.1\etc\ireport.conf:

# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch
jdkhome="C:/Program Files/Java/jdk1.7.0_45"

on linux (no spaces and standard file paths) its that much easier. keep your java 8 for other interesting projects...

See the MSDN reference table for maximum numbers/sizes.

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

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

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

Simply this should do:

php test.php

You can use math.ceil() to round up, and then multiply by 10

import math

def roundup(x):
    return int(math.ceil(x / 10.0)) * 10

To use just do

>>roundup(45)
50

now you can use rgba in CSS properties like this:

.class {
    background: rgba(0,0,0,0.5);
}

0.5 is the transparency, change the values according to your design.

Acknowledging the other excellent answer so far, the best code I've seen yet for this is in the documentation for the photo taking tool.

See the section entitled "Decode a Scaled Image".

http://developer.android.com/training/camera/photobasics.html

The solution it proposes is a resize then scale solution like the others here, but it's quite neat.

I've copied the code below as a ready-to-go function for convenience.

private void setPic(String imagePath, ImageView destination) {
    int targetW = destination.getWidth();
    int targetH = destination.getHeight();
    // Get the dimensions of the bitmap
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(imagePath, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW/targetW, photoH/targetH);

    // Decode the image file into a Bitmap sized to fill the View
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(imagePath, bmOptions);
    destination.setImageBitmap(bitmap);
}

Try this Using moment.js (Its quite easy to compute date operations in javascript)

firstDate.diff(secondDate, 'days', false);// true|false for fraction value

Result will give you number of days in integer.

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

You can use phpMyAdmin Style:

/**
 * block attempts to directly run this script
 */
if (getcwd() == dirname(__FILE__)) {
    die('Attack stopped');
}

Since sudo will not work with redirection >, I like the tee command for this purpose

echo "" | sudo tee fileName

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

I know this is an old question, but I faced the same problem recently in Laravel 7 application. To make renaming columns work I used a tip from this answer where instead of composer require doctrine/dbal I have issued composer require doctrine/dbal:^2.12.1 because the latest version of doctrine/dbal still throws an error.

Just keep in mind that if you already use a higher version, this answer might not be appropriate for you.

I just went to the file system and deleted the file directly, then continued with git checkout and it worked.

I've had the problem occur several times and it may be related to developers doing delete, push, re-add, push or some such thing.

A simple solution is to install jshon library :

jshon -l < /tmp/test.json

So I had a project that required downloading assets from firebase storage, so I had to solve this problem myself. Here is How :

1- First, make a model data for example class Choice{}, In that class defines a String variable called image Name so it will be like that

class Choice {
    .....
    String imageName;
}

2- from a database/firebase database, go and hardcode the image names to the objects, so if you have image name called Apple.png, create the object to be

Choice myChoice = new Choice(...,....,"Apple.png");

3- Now, get the link for the assets in your firebase storage which will be something like that

gs://your-project-name.appspot.com/

like this one

4- finally, initialize your firebase storage reference and start getting the files by a loop like that

storageRef = storage.getReferenceFromUrl(firebaseRefURL).child(imagePath);

File localFile = File.createTempFile("images", "png");
storageRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {

@Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
    //Dismiss Progress Dialog\\
}

5- that's it

I have faced same problem with maven dependencies, eg: unfortunetly your maven dependencies deleted from your buildpath,then you people get lot of exceptions,if you follow below process you can easily resolve this issue.

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

Below is the implementation of how a function (callback API) can be converted to a promise.

function promisify(functionToExec) {
  return function() {
    var array = Object.values(arguments);
    return new Promise((resolve, reject) => {
      array.push(resolve)
      try {
         functionToExec.apply(null, array);
      } catch (error) {
         reject(error)
      }
    })
  }
}

// USE SCENARIO

function apiFunction (path, callback) { // Not a promise
  // Logic
}

var promisedFunction = promisify(apiFunction);

promisedFunction('path').then(()=>{
  // Receive the result here (callback)
})

// Or use it with await like this
let result = await promisedFunction('path');

It's simple, use:

val str: String = "%.2f".format(3.14159)

search your code you must be referring to color in color.xml in an xml drawable. go and give hex code instead of referencing....

Example: in drawable.xml you must have called

android:fillColor="@color/blue"

change it to android:fillColor="#ffaacc" hope it solve your problem...

I stumbled across this question to my self and I feel that a forked stream has some use cases that could prove valid. I wrote the code below as a consumer so that it does not do anything but you could apply it to functions and anything else you might come across.

class PredicateSplitterConsumer<T> implements Consumer<T>
{
  private Predicate<T> predicate;
  private Consumer<T>  positiveConsumer;
  private Consumer<T>  negativeConsumer;

  public PredicateSplitterConsumer(Predicate<T> predicate, Consumer<T> positive, Consumer<T> negative)
  {
    this.predicate = predicate;
    this.positiveConsumer = positive;
    this.negativeConsumer = negative;
  }

  @Override
  public void accept(T t)
  {
    if (predicate.test(t))
    {
      positiveConsumer.accept(t);
    }
    else
    {
      negativeConsumer.accept(t);
    }
  }
}

Now your code implementation could be something like this:

personsArray.forEach(
        new PredicateSplitterConsumer<>(
            person -> person.getDateOfBirth().isPresent(),
            person -> System.out.println(person.getName()),
            person -> System.out.println(person.getName() + " does not have Date of birth")));

Just suplement/add a way for defining the default value of arguments that is not assigned in key words when calling the function:

def func(**keywargs):
if 'my_word' not in keywargs:
    word = 'default_msg'
else:
    word = keywargs['my_word']
return word

call this by:

print(func())
print(func(my_word='love'))

you'll get:

default_msg
love

I have Visual Studio Code version 1.27.2 and can do this:

Compare two files

1. Drag and drop the two files into Visual Studio Code
2. Select both files and select Select for Compare from the context menu
3. Then you see the diff
4. With Alt+F5 you can jump to the next diff

Compare two in-memory documents or tabs

Sometimes, you don't have two files but want to copy text from somewhere and do a quick diff without having to save the contents to files first. Then you can do this:

1. Open two tabs by hitting Ctrl+N twice:
2. Paste your first text sample from the clipboard to the first tab and the second text sample from the clipboard to the second tab
3. Select the first document Untitled-1 with Select for Compare:
4. Select the second document Untitled-2 with Compare with Selected:
5. Then you see the diff:

const char S[] = "ABCD";

This should work. i use this notation only and it works perfectly fine for me. I don't know how you are using.

Maybe EXISTS can help.

and exists (select 1 from @DocumentNames where pcd.Name like DocName+'%' or CD.DocumentName like DocName+'%')

$.map is probably the most efficient way to do this.

var options = $('#selectBox option');

var values = $.map(options ,function(option) {
    return option.value;
});

You can add change options to $('#selectBox option:selected') if you only want the ones that are selected.

The first line selects all of the checkboxes and puts their jQuery element into a variable. We then use the .map function of jQuery to apply a function to each of the elements of that variable; all we are doing is returning the value of each element as that is all we care about. Because we are returning them inside of the map function it actually builds an array of the values just as requested.

As someone who worked extensively on payment platforms, including one mobile payments application (MyCheck), I would say that you need to delegate this behaviour to the server, no user name or password for the payment processor (whichever it is) should be stored or hardcoded in the mobile application, that's the last thing you want, because the source can be understood even when if you obfuscate the code.

Also, you shouldn't store credit cards or payment tokens on the application, everything should be, again, delegated to a service you built, it will also allow you later on, be PCI-compliant more easily, and the Credit Card companies won't breath down your neck (like they did for us).

We have following steps:

1. First you need to install typescript

   npm install -g typescript
   

2. Create one file helloworld.ts

   function hello(person){
      return "Hello, " + person;
   }
   let user = "Aamod Tiwari";
   const result = hello(user);
   console.log("Result", result)
   

3. Open command prompt and type the following command

   tsc helloworld.ts
   

4. Again run the command

   node helloworld.js
   

5. Result will display on console

I use the following to successfully redirect all pages of my domain from http to https:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Note this will redirect using the 301 'permanently moved' redirect, which will help transfer your SEO rankings.

To redirect using the 302 'temporarily moved' change [R=302,L]

If you want to edit the decoded JSON, try getting it as an associative array instead of an array of objects.

$data = json_decode($json, TRUE);

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

This article is a good overview: http://office.microsoft.com/en-us/sharepoint-foundation-help/manage-lists-and-libraries-with-many-items-HA010377496.aspx

The Charset used in the POST will match that of the Charset specified in the HTML hosting the form. Hence if your form is sent using UTF-8 encoding that is the encoding used for the posted content. The URL encoding is applied after the values are converted to the set of octets for the character encoding.

It is not possible to tell whether a user will be signed when a page starts loading, there is a work around though.

You can memorize last auth state to localStorage to persist it between sessions and between tabs.

Then, when page starts loading, you can optimistically assume the user will be re-signed in automatically and postpone the dialog until you can be sure (ie after onAuthStateChanged fires). Otherwise, if the localStorage key is empty, you can show the dialog right away.

The firebase onAuthStateChanged event will fire roughly 2 seconds after a page load.

// User signed out in previous session, show dialog immediately because there will be no auto-login
if (!localStorage.getItem('myPage.expectSignIn')) showDialog() // or redirect to sign-in page

firebase.auth().onAuthStateChanged(user => {
  if (user) {
    // User just signed in, we should not display dialog next time because of firebase auto-login
    localStorage.setItem('myPage.expectSignIn', '1')
  } else {
    // User just signed-out or auto-login failed, we will show sign-in form immediately the next time he loads the page
    localStorage.removeItem('myPage.expectSignIn')

    // Here implement logic to trigger the login dialog or redirect to sign-in page, if necessary. Don't redirect if dialog is already visible.
    // e.g. showDialog()
  }
})

<Router>
  <Switch>
    <PrivateRoute
      exact path={routes.DASHBOARD}
      component={pages.Dashboard}
    />
...

And this is how my PrivateRoute is implemented:

export default function PrivateRoute(props) {
  return firebase.auth().currentUser != null
    ? <Route {...props}/>
    : localStorage.getItem('myPage.expectSignIn')
      // if user is expected to sign in automatically, display Spinner, otherwise redirect to login page.
      ? <Spinner centered size={400}/>
      : (
        <>
          Redirecting to sign in page.
          { location.replace(`/login?from=${props.path}`) }
        </>
      )
}

    // Using router Redirect instead of location.replace
    // <Redirect
    //   from={props.path}
    //   to={{pathname: routes.SIGN_IN, state: {from: props.path}}}
    // />

Use that code it definitely works and I modified it.

When it comes to float numbers, you can use format specifiers:

f'{value:{width}.{precision}}'

where:

• value is any expression that evaluates to a number
• width specifies the number of characters used in total to display, but if value needs more space than the width specifies then the additional space is used.
• precision indicates the number of characters used after the decimal point

What you are missing is the type specifier for your decimal value. In this link, you an find the available presentation types for floating point and decimal.

Here you have some examples, using the f (Fixed point) presentation type:

# notice that it adds spaces to reach the number of characters specified by width
In [1]: f'{1 + 3 * 1.5:10.3f}'
Out[1]: '     5.500'

# notice that it uses more characters than the ones specified in width
In [2]: f'{3000 + 3 ** (1 / 2):2.1f}' 
Out[2]: '3001.7'

In [3]: f'{1.2345 + 4 ** (1 / 2):9.6f}'
Out[3]: ' 3.234500'

# omitting width but providing precision will use the required characters to display the number with the the specified decimal places
In [4]: f'{1.2345 + 3 * 2:.3f}' 
Out[4]: '7.234'

# not specifying the format will display the number with as many digits as Python calculates
In [5]: f'{1.2345 + 3 * 0.5}'
Out[5]: '2.7344999999999997'

To minimize the duty of the server make it simple:

.htaccess

ErrorDocument 403 "Forbidden"

PHP

header('HTTP/1.0 403 Forbidden');

die(); // or your message: die('Forbidden');

So I figured out what is wrong with this statement:

Import-Csv H:\Programs\scripts\SomeText.csv |`

(Original)

Import-Csv H:\Programs\scripts\SomeText.csv -Delimiter "|"

(Proposed, You must use quotations; otherwise, it will not work and ISE will give you an error)

It requires the -Delimiter "|", in order for the variable to be populated with an array of items. Otherwise, Powershell ISE does not display the list of items.

I cannot say that I would recommend the | operator, since it is used to pipe cmdlets into one another.

I still cannot get the if statement to return true and output the values entered via the prompt.

If anyone else can help, it would be great. I still appreciate the post, it has been very helpful!

On Windows 10, to create the virtual environment, I replace "pip mkvirtualenv myproject" by "mkvirtualenv myproject" and that works well.

Here is a technique I use that has worked well:

<div>_x000D_
    <div style="display: table-cell; width: 100%">&nbsp;</div>_x000D_
    <div style="display: table-cell; white-space: nowrap;">Something Here</div>_x000D_
</div>

This answer is plagiarizer from several sources on StackOverflow - most of them above, but I've forgotten the others - sorry. It's simple and scripts run "as is". For releases you test you script, then copy it to the server and Stop/Start the associated service. And it should work for all scripting languages (Python, Perl, node.js), plus batch scripts such as GitBash, PowerShell, even old DOS bat scripts. pyGlue is the glue that sits between Windows Services and your script.

'''
A script to create a Windows Service, which, when started, will run an executable with the specified parameters.
Optionally, you can also specify a startup directory

To use this script you MUST define (in class Service)
1. A name for your service (short - preferably no spaces)
2. A display name for your service (the name visibile in Windows Services)
3. A description for your service (long details visible when you inspect the service in Windows Services)
4. The full path of the executable (usually C:/Python38/python.exe or C:WINDOWS/System32/WindowsPowerShell/v1.0/powershell.exe
5. The script which Python or PowerShell will run(or specify None if your executable is standalone - in which case you don't need pyGlue)
6. The startup directory (or specify None)
7. Any parameters for your script (or for your executable if you have no script)

NOTE: This does not make a portable script.
The associated '_svc_name.exe' in the dist folder will only work if the executable,
(and any optional startup directory) actually exist in those locations on the target system

Usage: 'pyGlue.exe [options] install|update|remove|start [...]|stop|restart [...]|debug [...]'
Options for 'install' and 'update' commands only:
        --username domain\\username : The Username the service is to run under
        --password password : The password for the username
        --startup [manual|auto|disabled|delayed] : How the service starts, default = manual
        --interactive : Allow the service to interact with the desktop.
        --perfmonini file: .ini file to use for registering performance monitor data
        --perfmondll file: .dll file to use when querying the service for performance data, default = perfmondata.dll
Options for 'start' and 'stop' commands only:
        --wait seconds: Wait for the service to actually start or stop.
                If you specify --wait with the 'stop' option, the service and all dependent services will be stopped,
                each waiting the specified period.

Now there's a bit of editing and you don't want all your services called 'pyGlue'. So there's a script (build.sh) to plug in the bits and create a customized 'pyGlue' and create an '.exe'.

Installation - copy the '.exe' the server and the script to the specified folder. Run the '.exe', as Administrator, with the 'install' option. Open Windows Services, as Adminstrator, and start you service. For upgrade, just copy the new version of the script and Stop/Start the service.

Now every server is different - different installations of Python, different folder structures. I maintain a folder for every server, with a copy of pyGlue.py and build.sh. And I create a 'serverBuild.sh' script for rebuilding all the service on that server.

# A script to build all the script based Services on this PC

I am not getting your question properly but as per your heading, you can convert any type of object to string by using toString() function on a String Object.

There are two ways to go about this:

I recommend the first option initially, due to its ease of implementation. Once you mature in your build processes, switch over to the second.

1. Poll the repository to see if changes occurred. This might "skip" a commit if two commits come in within the same polling interval. Description of how to do so here, note the fourth screenshot where you configure on the job a "build trigger" based on polling the repository (with a crontab-like configuration).

2. Configure your repository to have a post-commit hook which notifies Jenkins that a build needs to start. Description of how to do so here, in the section "post-commit hooks"

The SVN Tag feature is not part of the polling, it is part of promoting the current "head" of the source code to a tag, to snapshot a build. This allows you to refer to Jenkins buid #32 as SVN tag /tags/build-32 (or something similar).

If you see this warning:

warning: receiver 'MyCoolClass' is a forward class and corresponding @interface may not exist

you need to #import the file, but you can do that in your implementation file (.m), and use the @class declaration in your header file.

@class does not (usually) remove the need to #import files, it just moves the requirement down closer to where the information is useful.

For Example

If you say @class MyCoolClass, the compiler knows that it may see something like:

MyCoolClass *myObject;

It doesn't have to worry about anything other than MyCoolClass is a valid class, and it should reserve room for a pointer to it (really, just a pointer). Thus, in your header, @class suffices 90% of the time.

However, if you ever need to create or access myObject's members, you'll need to let the compiler know what those methods are. At this point (presumably in your implementation file), you'll need to #import "MyCoolClass.h", to tell the compiler additional information beyond just "this is a class".

RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. It does not include memory that is swapped out. It does include memory from shared libraries as long as the pages from those libraries are actually in memory. It does include all stack and heap memory.

VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.

So if process A has a 500K binary and is linked to 2500K of shared libraries, has 200K of stack/heap allocations of which 100K is actually in memory (rest is swapped or unused), and it has only actually loaded 1000K of the shared libraries and 400K of its own binary then:

RSS: 400K + 1000K + 100K = 1500K
VSZ: 500K + 2500K + 200K = 3200K

Since part of the memory is shared, many processes may use it, so if you add up all of the RSS values you can easily end up with more space than your system has.

The memory that is allocated also may not be in RSS until it is actually used by the program. So if your program allocated a bunch of memory up front, then uses it over time, you could see RSS going up and VSZ staying the same.

There is also PSS (proportional set size). This is a newer measure which tracks the shared memory as a proportion used by the current process. So if there were two processes using the same shared library from before:

PSS: 400K + (1000K/2) + 100K = 400K + 500K + 100K = 1000K

Threads all share the same address space, so the RSS, VSZ and PSS for each thread is identical to all of the other threads in the process. Use ps or top to view this information in linux/unix.

There is way more to it than this, to learn more check the following references:

See below: content view in scrollview vertical and horizontal centralized. you got ambiguity error, always make sure two added into scrollview from your content view is 1).button space to container.2)trailing space to constraint that is highlighted in screenshot,

these constraint means in scroll is how much you can scroll after your content view height or width.

it may help you.

If you want to create new component without .spec file, you can use

ng g c component-name --spec false

You can find these options using ng g c --help

Hint is displayed correctly with

android:inputType="textPassword"

and

android:gravity="center"

if you set also

android:ellipsize="start"

This will work fast:

Case 1 - File2 = File1 + extra text appended.

grep -Fxvf File2.txt File1.txt >> File3.txt

File 1: 80 Lines File 2: 100 Lines File 3: 20 Lines

I was facing the same situation.

I begin by declaring the structures I need:

Set<String> myKeysInSet = null; String[] myArrayOfString = null;

In my case, I have a JSON object and I need all the keys in this JSON to be stored in an array of strings. Using the GSON library, I use JSON.keySet() to get the keys and move to my Set :

myKeysInSet = json_any.keySet();

With this, I have a Set structure with all the keys, as I needed it. So I just need to the values to my Array of Strings. See the code below:

myArrayOfString = myKeysInSet.toArray(new String[myKeysInSet.size()]);

This was my first answer in StackOverflow. Sorry for any error :D

You get a horizontal straight line because it did not converge.

Better convergence is attained if the first parameter of the fitting (p0) is put as max(y), 5 in the example, instead of 1.

I suggest you read this

Swift 2.0+

Now with Swift 2.0 you can just use Float(Wage.text) which returns a Float? type. More clear than the below solution which just returns 0.

If you want a 0 value for an invalid Float for some reason you can use Float(Wage.text) ?? 0 which will return 0 if it is not a valid Float.

Old Solution

The best way to handle this is direct casting:

var WageConversion = (Wage.text as NSString).floatValue

I actually created an extension to better use this too:

extension String {
    var floatValue: Float {
        return (self as NSString).floatValue
    }
}

Now you can just call var WageConversion = Wage.text.floatValue and allow the extension to handle the bridge for you!

This is a good implementation since it can handle actual floats (input with .) and will also help prevent the user from copying text into your input field (12p.34, or even 12.12.41).

Obviously, if Apple does add a floatValue to Swift this will throw an exception, but it may be nice in the mean time. If they do add it later, then all you need to do to modify your code is remove the extension and everything will work seamlessly, since you will already be calling .floatValue!

Also, variables and constants should start with a lower case (including IBOutlets)

See that your statements refer to "elements of the DOM", which are things such as the HTML tags (A, INPUT, etc). Thse statements simply mean that multiple CSS classes may be assigned to one such element.

list1 = (x[0] for x in source_list)
list2 = (x[1] for x in source_list)

Sorry guys.

You can't rely on the image load event to fire but you can kind of rely on it in some situations and fallback to a maximum load time allowed. In this case, 10 seconds. I wrote this and it lives on production code for when people want to link images on a form post.

function loadImg(options, callback) {
  var seconds = 0,
  maxSeconds = 10,
  complete = false,
  done = false;

  if (options.maxSeconds) {
    maxSeconds = options.maxSeconds;
  }

  function tryImage() {
    if (done) { return; }
    if (seconds >= maxSeconds) {
      callback({ err: 'timeout' });
      done = true;
      return;
    }
    if (complete && img.complete) {
      if (img.width && img.height) {
        callback({ img: img });
        done = true;
        return;
      }
      callback({ err: '404' });
      done = true;
      return;
    } else if (img.complete) {
      complete = true;
    }
    seconds++;
    callback.tryImage = setTimeout(tryImage, 1000);
  }
  var img = new Image();
  img.onload = tryImage();
  img.src = options.src;
  tryImage();
}

use like so:

loadImage({ src : 'http://somewebsite.com/image.png', maxSeconds : 10 }, function(status) {
  if(status.err) {
    // handle error
    return;
  }
  // you got the img within status.img
});

According to http://khason.net/blog/how-to-use-systemdrawingbitmap-hbitmap-in-wpf/

   [DllImport("gdi32")]
   static extern int DeleteObject(IntPtr o);

   public static BitmapSource loadBitmap(System.Drawing.Bitmap source)
   {
       IntPtr ip = source.GetHbitmap();
       BitmapSource bs = null;
       try
       {
           bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(ip, 
              IntPtr.Zero, Int32Rect.Empty, 
              System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());
       }
       finally
       {
           DeleteObject(ip);
       }

       return bs;
   }

It gets System.Drawing.Bitmap (from WindowsBased) and converts it into BitmapSource, which can be actually used as image source for your Image control in WPF.

image1.Source = YourUtilClass.loadBitmap(SomeBitmap);

You set the DisplayMemberPath and the SelectedValuePath to "Name", so I assume that you have a class PhoneBookEntry with a public property Name.

Have you set the DataContext to your ConnectionViewModel object?

I copied you code and made some minor modifications, and it seems to work fine. I can set the viewmodels PhoneBookEnty property and the selected item in the combobox changes, and I can change the selected item in the combobox and the view models PhoneBookEntry property is set correctly.

Here is my XAML content:

<Window x:Class="WpfApplication6.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300">
<Grid>
    <StackPanel>
        <Button Click="Button_Click">asdf</Button>
        <ComboBox ItemsSource="{Binding Path=PhonebookEntries}"
                  DisplayMemberPath="Name"
                  SelectedValuePath="Name"
                  SelectedValue="{Binding Path=PhonebookEntry}" />
    </StackPanel>
</Grid>
</Window>

And here is my code-behind:

namespace WpfApplication6
{

    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            ConnectionViewModel vm = new ConnectionViewModel();
            DataContext = vm;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ((ConnectionViewModel)DataContext).PhonebookEntry = "test";
        }
    }

    public class PhoneBookEntry
    {
        public string Name { get; set; }

        public PhoneBookEntry(string name)
        {
            Name = name;
        }

        public override string ToString()
        {
            return Name;
        }
    }

    public class ConnectionViewModel : INotifyPropertyChanged
    {
        public ConnectionViewModel()
        {
            IList<PhoneBookEntry> list = new List<PhoneBookEntry>();
            list.Add(new PhoneBookEntry("test"));
            list.Add(new PhoneBookEntry("test2"));
            _phonebookEntries = new CollectionView(list);
        }

        private readonly CollectionView _phonebookEntries;
        private string _phonebookEntry;

        public CollectionView PhonebookEntries
        {
            get { return _phonebookEntries; }
        }

        public string PhonebookEntry
        {
            get { return _phonebookEntry; }
            set
            {
                if (_phonebookEntry == value) return;
                _phonebookEntry = value;
                OnPropertyChanged("PhonebookEntry");
            }
        }

        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        public event PropertyChangedEventHandler PropertyChanged;
    }
}

Edit: Geoffs second example does not seem to work, which seems a bit odd to me. If I change the PhonebookEntries property on the ConnectionViewModel to be of type ReadOnlyCollection, the TwoWay binding of the SelectedValue property on the combobox works fine.

Maybe there is an issue with the CollectionView? I noticed a warning in the output console:

System.Windows.Data Warning: 50 : Using CollectionView directly is not fully supported. The basic features work, although with some inefficiencies, but advanced features may encounter known bugs. Consider using a derived class to avoid these problems.

Edit2 (.NET 4.5): The content of the DropDownList can be based on ToString() and not of DisplayMemberPath, while DisplayMemberPath specifies the member for the selected and displayed item only.

Updated eclipse.ini file with key value property -Dosgi.requiredJavaVersion=1.7 (or) 1.8 whichever applicable. - it works for me.

jQuery.load() is probably the easiest way to load data asynchronously using a selector, but you can also use any of the jquery ajax methods (get, post, getJSON, ajax, etc.)

Note that load allows you to use a selector to specify what piece of the loaded script you want to load, as in

$("#mydiv").load(location.href + " #mydiv");

Note that this technically does load the whole page and jquery removes everything but what you have selected, but that's all done internally.

There is nothing bad or better, It just depends on the precedence of operators. Since || has higher precedence than or, so || is mostly used.

Delete the CMakeCache.txt file and try this:

cmake -G %1 -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DBUILD_TESTS=ON ..

You have to enter all your command-line definitions before including the path.

If you want a "Null, empty or white space" check, you can avoid unnecessary string manipulation with LTRIM and RTRIM like this.

IF COALESCE(PATINDEX('%[^ ]%', @parameter), 0) > 0
    RAISERROR ...

Normally the ON clause comes from the mapping's join columns, but the JPA 2.1 draft allows for additional conditions in a new ON clause.

I couldn't get the SDK to install properly (some of the files seemed unsigned, something like that). I found another solution here and that seems to work okay for me. It doesn't require installation of new files at all. Basically, what you do is:

Edit the .csproj file in a text editor, and add:

<Reference Include="System.Management.Automation" />

to the relevant section.

Hope this helps.

The strpos() finds the offset of the underscore, then substr grabs everything from that index plus 1, onwards.

$data = "123_String";    
$whatIWant = substr($data, strpos($data, "_") + 1);    
echo $whatIWant;

If you also want to check if the underscore character (_) exists in your string before trying to get it, you can use the following:

if (($pos = strpos($data, "_")) !== FALSE) { 
    $whatIWant = substr($data, $pos+1); 
}

I have made a simple solution for this in ReactJS you can use this in Vanilla Javascript aswell.

Create new block formatting context

You can use display: flow-root on the parent element to prevent margin collapsing through the containing element as it creates new Block Formatting Context.

Changing the value of the overflow property to auto or using flexbox will have the same effect.

If you want to Place cursor at the end of text in EditText view

 EditText rename;
 String title = "title_goes_here";
 int counts = (int) title.length();
 rename.setSelection(counts);
 rename.setText(title);

In Swift 4, you can also set the background color of your table cell globally (taken from here):

let backgroundColorView = UIView()
backgroundColorView.backgroundColor = UIColor.red
UITableViewCell.appearance().selectedBackgroundView = backgroundColorView

You can simply do

print 2*'hello'

With HTML5, you can now use the placeholder attribute like this:

<form action="demo_form.asp">
  <input type="text" name="fname" placeholder="First name"><br>
  <input type="text" name="lname" placeholder="Last name"><br>
  <input type="submit" value="Submit">
</form>

You could search for the corresponding key or you could "invert" the dictionary, but considering how you use it, it would be best if you just iterated over key/value pairs in the first place, which you can do with items(). Then you have both directly in variables and don't need a lookup at all:

for key, value in PIX0.items():
    NUM = input("What is the Resolution of %s?"  % key)
    if NUM == value:

You can of course use that both ways then.

Or if you don't actually need the dictionary for something else, you could ditch the dictionary and have an ordinary list of pairs.

I followed the answers here but when I tried to connect with my new user, I got an error message stating "The server principal 'newuser' is not able to access the database 'master' under the current security context".

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

With Java 9, we get access to jshell, so one can write something like this:

import java.lang.StringBuilder;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;

public class Eval {
    public static void main(String[] args) throws IOException {
        try(JShell js = JShell.create(); BufferedReader br = new BufferedReader(new InputStreamReader(System.in))) {

            js.onSnippetEvent(snip -> {
                if (snip.status() == jdk.jshell.Snippet.Status.VALID) {
                    System.out.println("? " + snip.value());
                }
            });

            System.out.print("> ");
            for (String line = br.readLine(); line != null; line = br.readLine()) {
                js.eval(js.sourceCodeAnalysis().analyzeCompletion(line).source());
                System.out.print("> ");
            }
        }
    }
}

Sample run:

> 1 + 2 / 4 * 3
? 1
> 32 * 121
? 3872
> 4 * 5
? 20
> 121 * 51
? 6171
>

Slightly op, but that's what Java currently has to offer

You can have multiple addresses separated by comma

if (cc.indexOf(',') > 0)
    message.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc));   
else
    message.setRecipient(Message.RecipientType.CC, new InternetAddress(cc));

By far the most efficient method is to use the SMALL and COUNTIF formula as shown below;

SMALL Returns the k-th smallest value in a data set.

=SMALL(A1:A100,COUNTIF($A$1:$A$100,0)+1)

Where the countif is counting the zeros in the range (+1) and is used to tell SMALL to return the k-th smallest value.

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

Just use this one, You have to use more when they are classes.

SELECT   Url='',
         p.ArtNo,
         p.[Description],
         p.Specification,
         CASE 
         WHEN 1 = 1 or 1 = 1 
            THEN 1 
         WHEN 2 = 2
             THEN 2
         WHEN 3 = 3
              THEN 3
          ELSE 0 
        END as Qty,
        p.NetPrice,
        [Status] = 0
  FROM  Product p (NOLOCK)

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

Considering everyone is posting older ways of hiding the ActionBar here is the proper way of implementing it within styles for AppCompat support library. Which I highly suggest moving toward if you haven't already.

Simply removing the ActionBar

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

If you are using the appcompat support libraries, this is the easiest and recommended way of hiding the ActionBar to make full screen or start implementing to toolbar within your layouts.

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Your Toolbar Color-->
    <item name="colorPrimary">@color/primary</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/primary_dark</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
     which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
     colorControlHighlight, and colorSwitchThumbNormal. -->
</style>

Then to change your toolbar color

<android.support.v7.widget.Toolbar
    android:id=”@+id/my_awesome_toolbar”
    android:layout_height=”wrap_content”
    android:layout_width=”match_parent”
    android:minHeight=”?attr/actionBarSize”
    android:background=”?attr/primary” />

Last note: Your Activity class should extend AppCompatActivity

public class MainActivity extends AppCompatActivity {

<!--Activity Items -->

}

Just my 2 cents. This code combines two matrices or data.frames into one. If one data structure have lower number of rows then missing rows will be added with NA values.

combine.df <- function(x, y) {
    rows.x <- nrow(x)
    rows.y <- nrow(y)
    if (rows.x > rows.y) {
        diff <- rows.x - rows.y
        df.na <- matrix(NA, diff, ncol(y))
        colnames(df.na) <- colnames(y)
        cbind(x, rbind(y, df.na))
    } else {
        diff <- rows.y - rows.x
        df.na <- matrix(NA, diff, ncol(x))
        colnames(df.na) <- colnames(x)
        cbind(rbind(x, df.na), y)
    }
}

df1 <- data.frame(1:10, row.names = 1:10)
df2 <- data.frame(1:5, row.names = 10:14)
combine.df(df1, df2)

In addition to @tadman's answer I removed the wrappers in /usr/local/bin as well as the file /etc/profile.d/rvm.

The wrappers include:

erb
gem
irb
rake
rdoc
ri
ruby
testrb

By using org.apache.http.client.HttpClient also you can easily do this with more readable way as below.

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

Within try catch you can insert

// 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);

This version is for German language but you can modifiy the $CHARSETS and the $TESTCHARS

class CharsetDetector
{
private static $CHARSETS = array(
"ISO_8859-1",
"ISO_8859-15",
"CP850"
);
private static $TESTCHARS = array(
"€",

    $normalized = self::__normalize($string);
    if(!strlen($normalized))return "UTF-8";
    $best = "UTF-8";
    $charcountbest = 0;
    foreach (self::$CHARSETS as $charset) {
        $str = self::__iconv($normalized, $charset);
        $charcount = 0;
        $stop   = mb_strlen( $str, "UTF-8");

        for( $idx = 0; $idx < $stop; $idx++)
        {
            $char = mb_substr( $str, $idx, 1, "UTF-8");
            foreach (self::$TESTCHARS as $testchar) {

                if($char == $testchar)
                {

                    $charcount++;
                    break;
                }
            }
        }
        if($charcount>$charcountbest)
        {
            $charcountbest=$charcount;
            $best=$charset;
        }
        //echo $text."<br />";
    }
    return $best;
}
private static function __normalize($str)
{

$len = strlen($str);
$ret = "";
for($i = 0; $i < $len; $i++){
    $c = ord($str[$i]);
    if ($c > 128) {
        if (($c > 247)) $ret .=$str[$i];
        elseif ($c > 239) $bytes = 4;
        elseif ($c > 223) $bytes = 3;
        elseif ($c > 191) $bytes = 2;
        else $ret .=$str[$i];
        if (($i + $bytes) > $len) $ret .=$str[$i];
        $ret2=$str[$i];
        while ($bytes > 1) {
            $i++;
            $b = ord($str[$i]);
            if ($b < 128 || $b > 191) {$ret .=$ret2; $ret2=""; $i+=$bytes-1;$bytes=1; break;}
            else $ret2.=$str[$i];
            $bytes--;
        }
    }

return $ret;

I use getActionCommand() to hear buttons. I apply the setActionCommand() to each button so that I can hear whenever an event is execute with event.getActionCommand("The setActionCommand() value of the button").

I use getSource() for JRadioButtons for example. I write methods that returns each JRadioButton so in my Listener Class I can specify an action each time a new JRadioButton is pressed. So for example:

public class SeleccionListener implements ActionListener, FocusListener {}

So with this I can hear button events and radioButtons events. The following are examples of how I listen each one:

public void actionPerformed(ActionEvent event) {
    if (event.getActionCommand().equals(GUISeleccion.BOTON_ACEPTAR)) {
        System.out.println("Aceptar pressed");
    }

In this case GUISeleccion.BOTON_ACEPTAR is a "public static final String" which is used in JButtonAceptar.setActionCommand(BOTON_ACEPTAR).

public void focusGained(FocusEvent focusEvent) {
    if (focusEvent.getSource().equals(guiSeleccion.getJrbDat())){
        System.out.println("Data radio button");
    }

In this one, I get the source of any JRadioButton that is focused when the user hits it. guiSeleccion.getJrbDat() returns the reference to the JRadioButton that is in the class GUISeleccion (this is a Frame)

Comment by @Niagaradad helped me. I was entering the wrong password the whole time.

Notice the error message

ERROR 1045 (28000): Access denied for user 'ayaz'@'localhost' (using password: YES)

It says, Password: Yes. That means I am sending the password to SQL and that is wrong.

Usually root account doesn't have password if you haven't set one. If you have installed mysql via homebrew then root account won't have a password.

Here is the comment.

so, not exactly the same then. NO means you are not sending a password to MySQL. YES means you are sending a password to MySQL but the incorrect one. Did you specifically set a password for the mysql root user when you installed MySQL? By default there is no password so you can use mysql -u root -p and hit enter.

Have not tested it yet, but the looks are better than the one Alex mentions.

The description at winginx.com/en/htaccess says:

About the htaccess to nginx converter

The service is to convert an Apache's .htaccess to nginx configuration instructions.

First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.

Note server instructions (e.g. php_value, etc.) are ignored.

The converter does not check syntax, including regular expressions and logic errors.

Please, check the result manually before use.

If you're just formatting a number, you can just provide the proper custom numeric format to make it a 3 digit string directly:

myString = 3.ToString("000");

Or, alternatively, use the standard D format string:

myString = 3.ToString("D3");

I agree with the compacity of the switch solution but IMO you're hijacking the switch here.
The purpose of the switch is to have different handling depending on the value.
If you had to explain your algo in pseudo-code, you'd use an if because, semantically, that's what it is: if whatever_error do this...
So unless you intend someday to change your code to have specific code for each error, I would use if.

You can use this to refresh an Activity from within itself.

finish();
startActivity(getIntent());

Summary of the alternatives:

capture this:

auto lambda = [this](){};

use a local reference to the member:

auto& tmp = grid;
auto lambda = [ tmp](){}; // capture grid by (a single) copy
auto lambda = [&tmp](){}; // capture grid by ref

C++14:

auto lambda = [ grid = grid](){}; // capture grid by copy
auto lambda = [&grid = grid](){}; // capture grid by ref

class HashMap:
    def __init__(self):
        self.size = 64

For Lists you can use

Collections.fill(arrayList, "-")

The way to reinstall Homebrew is completely remove it and start over. The Homebrew FAQ has a link to a shell script to uninstall homebrew.

If the only thing you've installed in /usr/local is homebrew itself, you can just rm -rf /usr/local/* /usr/local/.git to clear it out. But /usr/local/ is the standard Unix directory for all extra binaries, not just Homebrew, so you may have other things installed there. In that case uninstall_homebrew.sh is a better bet. It is careful to only remove homebrew's files and leave the rest alone.

Schema behaves seem like a parent object as seen in OOP world. so it's not a database itself. maybe this link is useful.

But, In MySQL, the two are equivalent. The keyword DATABASE or DATABASES can be replaced with SCHEMA or SCHEMAS wherever it appears. Examples:

• CREATE DATABASE <=> CREATE SCHEMA
• SHOW DATABASES <=> SHOW SCHEMAS

Documentation of MySQL

SCHEMA & DATABASE terms are something DBMS dependent.

A Table is a set of data elements (values) that is organized using a model of vertical columns (which are identified by their name) and horizontal rows. A database contains one or more(usually) Tables . And you store your data in these tables. The tables may be related with one another(See here).

Or you can do that with ES6 template literal:

<a :href="`/job/${r.id}`"

I have 2 tables like this:

> SELECT * FROM table_a;
+------+------+
| id   | name |
+------+------+
|    1 | row1 |
|    2 | row2 |
+------+------+

> SELECT * FROM table_b;
+------+------+------+
| id   | name | aid  |
+------+------+------+
|    3 | row3 |    1 |
|    4 | row4 |    1 |
|    5 | row5 | NULL |
+------+------+------+

INNER JOIN cares about both tables

INNER JOIN cares about both tables, so you only get a row if both tables have one. If there is more than one matching pair, you get multiple rows.

> SELECT * FROM table_a a INNER JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
+------+------+------+------+------+

It makes no difference to INNER JOIN if you reverse the order, because it cares about both tables:

> SELECT * FROM table_b b INNER JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
+------+------+------+------+------+

You get the same rows, but the columns are in a different order because we mentioned the tables in a different order.

LEFT JOIN only cares about the first table

LEFT JOIN cares about the first table you give it, and doesn't care much about the second, so you always get the rows from the first table, even if there is no corresponding row in the second:

> SELECT * FROM table_a a LEFT JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
|    2 | row2 | NULL | NULL | NULL |
+------+------+------+------+------+

Above you can see all rows of table_a even though some of them do not match with anything in table b, but not all rows of table_b - only ones that match something in table_a.

If we reverse the order of the tables, LEFT JOIN behaves differently:

> SELECT * FROM table_b b LEFT JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
|    5 | row5 | NULL | NULL | NULL |
+------+------+------+------+------+

Now we get all rows of table_b, but only matching rows of table_a.

RIGHT JOIN only cares about the second table

a RIGHT JOIN b gets you exactly the same rows as b LEFT JOIN a. The only difference is the default order of the columns.

> SELECT * FROM table_a a RIGHT JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
| NULL | NULL |    5 | row5 | NULL |
+------+------+------+------+------+

This is the same rows as table_b LEFT JOIN table_a, which we saw in the LEFT JOIN section.

Similarly:

> SELECT * FROM table_b b RIGHT JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
| NULL | NULL | NULL |    2 | row2 |
+------+------+------+------+------+

Is the same rows as table_a LEFT JOIN table_b.

No join at all gives you copies of everything

If you write your tables with no JOIN clause at all, just separated by commas, you get every row of the first table written next to every row of the second table, in every possible combination:

> SELECT * FROM table_b b, table_a;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    3 | row3 | 1    |    2 | row2 |
|    4 | row4 | 1    |    1 | row1 |
|    4 | row4 | 1    |    2 | row2 |
|    5 | row5 | NULL |    1 | row1 |
|    5 | row5 | NULL |    2 | row2 |
+------+------+------+------+------+

(This is from my blog post Examples of SQL join types)

Just like ASP.NET variant, except put the hidden input with the same name before the actual checkbox (of the same name). Only last values will be sent. This way if a box is checked then its name and value "on" is sent, whereas if it's unchecked then the name of the corresponding hidden input and whatever value you might like to give it will be sent. In the end you will get the $_POST array to read, with all checked and unchecked elements in it, "on" and "false" values, no duplicate keys. Easy to process in PHP.

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
    <script>
        function systemip(){
        document.getElementById("ip").value = myip
        console.log(document.getElementById("ip").value)
        }
    </script>

This would redirect with posted data

$(function() {
       $('<form action="url.php" method="post"><input type="hidden" name="name" value="value1"></input></form>').appendTo('body').submit().remove();
    });

    }

the .submit() function does the submit to url automatically
the .remove() function kills the form after submitting

Fall-through is really a handy thing, depending on what you're doing. Consider this neat and understandable way to arrange options:

switch ($someoption) {
  case 'a':
  case 'b':
  case 'c':
    // Do something
    break;

  case 'd':
  case 'e':
    // Do something else
    break;
}

Imagine doing this with if/else. It would be a mess.
