I had this error when I tried to create a replicationcontroller. The issue was, I wrongly spelt the nginx image name in template definition.

Note: This error occurs when kubernetes is unable to pull the specified image from the repository.

Referencing a channel within a conversation

To create a clickable reference to a channel in a Slack conversation, just type # followed by the channel name. For example: #general.

To grab a link to a channel through the Slack UI

To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:

The link would look like this:

https://yourteam.slack.com/messages/C69S1L3SS

Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.

To compose a URL for a channel based on channel name

https://yourteam.slack.com/channels/<channel_name>

Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.

To compose a URL for a direct message (DM) channel to a user

https://yourteam.slack.com/channels/<username>

You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

My problem was that apart from having

com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.X.X_XX.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

I had this trace as well:

Uncaught translation error: java.lang.IllegalArgumentException: already added: Lcom/mypackage/ClassX;

The problem was that I was adding the same class in two differents libraries. Removing the class/jar file from one of the libraries, the project run properly

NW.js

(Previously known as node-webkit)

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

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

Features

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

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

I had a similar problem after first pulling and starting a new solution. It was fixed in visual studio by first cleaning the project. Then restoring the packages. When I built again, there were no more type or namespace errors.

I'm not sure what kind of scheduled tasks you mean. If you mean stuff like "every hour, refresh foo.xml" type tasks, then use the Windows Scheduled Tasks system. (The "at" command, or via the controller.) Have it either run a console app or request a special page that kicks off the process.

Edit: I should add, this is an OK way to get your IIS app running at scheduled points too. So suppose you want to check your DB every 30 minutes and email reminders to users about some data, you can use scheduled tasks to request this page and hence get IIS processing things.

If your needs are more complex, you might consider creating a Windows Service and having it run a loop to do whatever processing you need. This also has the benefit of separating out the code for scaling or management purposes. On the downside, you need to deal with Windows services.

Maybe silly, but check that you inline script is AFTER you include the script tags.

Combining the following sources, the following code works on Windows, Linux and macOS using just the platform and os modules:

• cantdutchthis' answer for the mac command
• natka_m's comment for the Ubuntu command
• BananaAcid's answer for the Windows command
• Louis Brandy's answer for how to detect the OS
• nc3b's answer for how to detect the Linux distribution

tx = input("Text to say >>> ")
tx = repr(tx)

import os
import platform

syst = platform.system()
if syst == 'Linux' and platform.linux_distribution()[0] == "Ubuntu":
    os.system('spd-say %s' % tx)
elif syst == 'Windows':
    os.system('PowerShell -Command "Add-Type –AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).Speak(%s);"' % tx)
elif syst == 'Darwin':
    os.system('say %s' % tx)
else:
    raise RuntimeError("Operating System '%s' is not supported" % syst)

Note: This method is not secure and could be exploited by malicious text.

This code simulates a click on the burguer button to close the navbar by clicking on a link in the menu, keeping the fade out effect. Solution with typescript for angular 7. Avoid routerLink problems.

ToggleNavBar () {
    let element: HTMLElement = document.getElementsByClassName( 'navbar-toggler' )[ 0 ] as HTMLElement;
    if ( element.getAttribute( 'aria-expanded' ) == 'true' ) {
        element.click();
    }
}

<li class="nav-item" [routerLinkActive]="['active']">
    <a class="nav-link" [routerLink]="['link1']" title="link1" (click)="ToggleNavBar()">link1</a>
</li>

if you want to only search with attribute name with any value

from bs4 import BeautifulSoup
import re

soup= BeautifulSoup(html.text,'lxml')
results = soup.findAll("td", {"valign" : re.compile(r".*")})

as per Steve Lorimer better to pass True instead of regex

results = soup.findAll("td", {"valign" : True})

To expand upon dreamlax's example... If you want to send data along with the notification

In posting code:

NSDictionary *userInfo = 
[NSDictionary dictionaryWithObject:myObject forKey:@"someKey"];
[[NSNotificationCenter defaultCenter] postNotificationName: 
                       @"TestNotification" object:nil userInfo:userInfo];

In observing code:

- (void) receiveTestNotification:(NSNotification *) notification {

    NSDictionary *userInfo = notification.userInfo;
    MyObject *myObject = [userInfo objectForKey:@"someKey"];
}

stringByTrimmingCharactersInSet only removes characters from the beginning and the end of the string, not the ones in the middle.

1) If you need to remove only a given character (say the space character) from your string, use:

[yourString stringByReplacingOccurrencesOfString:@" " withString:@""]

2) If you really need to remove a set of characters (namely not only the space character, but any whitespace character like space, tab, unbreakable space, etc), you could split your string using the whitespaceCharacterSet then joining the words again in one string:

NSArray* words = [yourString componentsSeparatedByCharactersInSet :[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString* nospacestring = [words componentsJoinedByString:@""];

Note that this last solution has the advantage of handling every whitespace character and not only spaces, but is a bit less efficient that the stringByReplacingOccurrencesOfString:withString:. So if you really only need to remove the space character and are sure you won't have any other whitespace character than the plain space char, use the first method.

Experienced this myself when using requests:

This is extremely insecure; use only as a last resort! (See rdlowrey's comment.)

requests.get('https://github.com', verify=True)

Making that verify=False did the trick for me.

` Please include either of these:

The question specifically mentions a full box and not an empty box and not using proof environment from amsthm package. Hence, an option may be to use the command \QED from the package stix. It reproduces the character U+220E (end of proof, ?).

In WPF there are certain 'container' controls that automatically resize their contents and there are some that don't.

Here are some that do not resize their contents (I'm guessing that you are using one or more of these):

StackPanel
WrapPanel
Canvas
TabControl

Here are some that do resize their contents:

Grid
UniformGrid
DockPanel

Therefore, it is almost always preferable to use a Grid instead of a StackPanel unless you do not want automatic resizing to occur. Please note that it is still possible for a Grid to not size its inner controls... it all depends on your Grid.RowDefinition and Grid.ColumnDefinition settings:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="100" /> <!--<<< Exact Height... won't resize -->
        <RowDefinition Height="Auto" /> <!--<<< Will resize to the size of contents -->
        <RowDefinition Height="*" /> <!--<<< Will resize taking all remaining space -->
    </Grid.RowDefinitions>
</Grid>

You can find out more about the Grid control from the Grid Class page on MSDN. You can also find out more about these container controls from the WPF Container Controls Overview page on MSDN.

Further resizing can be achieved using the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties. The default value of these properties is Stretch which will stretch elements to fit the size of their containing controls. However, when they are set to any other value, the elements will not stretch.

UPDATE >>>

In response to the questions in your comment:

Use the Grid.RowDefinition and Grid.ColumnDefinition settings to organise a basic structure first... it is common to add Grid controls into the cells of outer Grid controls if need be. You can also use the Grid.ColumnSpan and Grid.RowSpan properties to enable controls to span multiple columns and/or rows of a Grid.

It is most common to have at least one row/column with a Height/Width of "*" which will fill all remaining space, but you can have two or more with this setting, in which case the remaining space will be split between the two (or more) rows/columns. 'Auto' is a good setting to use for the rows/columns that are not set to '"*"', but it really depends on how you want the layout to be.

There is no Auto setting that you can use on the controls in the cells, but this is just as well, because we want the Grid to size the controls for us... therefore, we don't want to set the Height or Width of these controls at all.

The point that I made about the FrameworkElement.HorizontalAlignment and FrameworkElement.VerticalAlignment properties was just to let you know of their existence... as their default value is already Stretch, you don't generally need to set them explicitly.

The Margin property is generally just used to space your controls out evenly... if you drag and drop controls from the Visual Studio Toolbox, VS will set the Margin property to place your control exactly where you dropped it but generally, this is not what we want as it will mess with the auto sizing of controls. If you do this, then just delete or edit the Margin property to suit your needs.

I did the following:

void BrowserDocumentCompleted(object sender,
        WebBrowserDocumentCompletedEventArgs e)
{
  if (e.Url.AbsolutePath != (sender as WebBrowser).Url.AbsolutePath)
    return; 

  //The page is finished loading 
}

The last page loaded tends to be the one navigated to, so this should work.

From here.

Try this:

sizeof(list) / sizeof(list[0]);

Because this question is tagged C++, it is always recommended to use std::vector in C++ rather than using conventional C-style arrays.

An array-type is implicitly converted into a pointer-type when you pass it to a function. Have a look at this.

In order to correctly print the sizeof an array inside any function, pass the array by reference to that function (but you need to know the size of that array in advance).

You would do it like so for the general case

template<typename T,int N> 
//template argument deduction
int size(T (&arr1)[N]) //Passing the array by reference 
{
   return sizeof(arr1)/sizeof(arr1[0]); //Correctly returns the size of 'list'
   // or
   return N; //Correctly returns the size too [cool trick ;-)]
}

The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!

If you want to hide them anyway: error_reporting(0);

Got my own answer: Using this function from the data from the textarea solves the problem:

function mynl2br($text) { 
   return strtr($text, array("\r\n" => '<br />', "\r" => '<br />', "\n" => '<br />')); 
} 

More here: http://php.net/nl2br

We can do this using data() method. C++11 provides this method.

Code Snippet

#include<bits/stdc++.h>
using namespace std;


int main()
{
  ios::sync_with_stdio(false);

  vector<int>v = {7, 8, 9, 10, 11};
  int *arr = v.data();

  for(int i=0; i<v.size(); i++)
  {
    cout<<arr[i]<<" ";
  }

  return 0;
}

If by autostart you mean auto start on phone bootup then you should register a BroadcastReceiver for the BOOT_COMPLETED Intent. Android systems broadcasts that intent once boot is completed.

Once you receive that intent you can launch a Service that can do whatever you want to do.

Keep note though that having a Service running all the time on the phone is generally a bad idea as it eats up system resources even when it is idle. You should launch your Service / application only when needed and then stop it when not required.

As far as I can tell, whether you throw an exception, or you return Request.CreateErrorResponse, the result is the same. If you look at the source code for System.Web.Http.dll, you will see as much. Take a look at this general summary, and a very similar solution that I have made: Web Api, HttpError, and the behavior of exceptions

You should use container-fluid, not container. See example: http://www.bootply.com/onAFpJcslS

What you need to do is to create a new commit with the same details as the current HEAD commit, but with the parent as the previous version of HEAD. git reset --soft will move the branch pointer so that the next commit happens on top of a different commit from where the current branch head is now.

# Move the current head so that it's pointing at the old commit
# Leave the index intact for redoing the commit.
# HEAD@{1} gives you "the commit that HEAD pointed at before 
# it was moved to where it currently points at". Note that this is
# different from HEAD~1, which gives you "the commit that is the
# parent node of the commit that HEAD is currently pointing to."
git reset --soft HEAD@{1}

# commit the current tree using the commit details of the previous
# HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the
# previous command. It's now pointing at the erroneously amended commit.)
git commit -C HEAD@{1}

A silly bug that got me: the joins failed because index dtypes differed. This was not obvious as both tables were pivot tables of the same original table. After reset_index, the indices looked identical in Jupyter. It only came to light when saving to Excel...

Fixed with: df1[['key']] = df1[['key']].apply(pd.to_numeric)

Hopefully this saves somebody an hour!

In your while statement just replace mysql_fetch_row with mysql_fetch_array or mysql_fetch_assoc... whichever works...

Depends on which "cloud" you would want to use. If it is Google App Engine, you can use Java or Python. Groovy too is supported on Google App Engine which runs on jvm. If you are going with Amazon, you can pretty much install any OS (Amazon Machine Images) you would like with any application server and use any language depending on the application servers support for the language. But doing something like that would mean a lot of technical understanding of scalability concepts. Some of the services might be provided off the shelf like DB services, storage etc. I heard about ruby and Heroku (another cloud application platform). But dont have experience with it.

Personally I prefer Java/Groovy for such things because of the vast libraries and tools available.

Just to help anyone with this problem (locking requests when executing another one from the same session)...

Today I started to solve this issue and, after some hours of research, I solved it by removing the Session_Start method (even if empty) from the Global.asax file.

This works in all projects I've tested.

How about some recursion:

private static string ReturnSize(double size, string sizeLabel)
{
  if (size > 1024)
  {
    if (sizeLabel.Length == 0)
      return ReturnSize(size / 1024, "KB");
    else if (sizeLabel == "KB")
      return ReturnSize(size / 1024, "MB");
    else if (sizeLabel == "MB")
      return ReturnSize(size / 1024, "GB");
    else if (sizeLabel == "GB")
      return ReturnSize(size / 1024, "TB");
    else
      return ReturnSize(size / 1024, "PB");
  }
  else
  {
    if (sizeLabel.Length > 0)
      return string.Concat(size.ToString("0.00"), sizeLabel);
    else
      return string.Concat(size.ToString("0.00"), "Bytes");
  }
}

Then you call it:

return ReturnSize(size, string.Empty);

You may set this in your application.yml file to resolve Instant time, which is Date API in java8:

An excerpt from the RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1:

The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:

• Annotation of existing resources;
• Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
• Providing a block of data, such as the result of submitting a form, to a data-handling process;
• Extending a database through an append operation.

It's the same as the Objective-C API, but uses Swift's syntax.

Swift 4.2 & Swift 5:

NotificationCenter.default.addObserver(
    self,
    selector: #selector(self.batteryLevelChanged),
    name: UIDevice.batteryLevelDidChangeNotification,
    object: nil)

If your observer does not inherit from an Objective-C object, you must prefix your method with @objc in order to use it as a selector.

@objc private func batteryLevelChanged(notification: NSNotification){     
    //do stuff using the userInfo property of the notification object
}

See NSNotificationCenter Class Reference, Interacting with Objective-C APIs

3 answers, which you can combine:

1. Set implicit wait immediately after creating the web driver instance:

   _ = driver.Manage().Timeouts().ImplicitWait;

   This will try to wait until the page is fully loaded on every page navigation or page reload.

2. After page navigation, call JavaScript return document.readyState until "complete" is returned. The web driver instance can serve as JavaScript executor. Sample code:

   C#

   new WebDriverWait(driver, MyDefaultTimeout).Until(
   d => ((IJavaScriptExecutor) d).ExecuteScript("return document.readyState").Equals("complete"));
   

   Java

   new WebDriverWait(firefoxDriver, pageLoadTimeout).until(
         webDriver -> ((JavascriptExecutor) webDriver).executeScript("return document.readyState").equals("complete"));
   

3. Check if the URL matches the pattern you expect.

Bundle bundle = new Bundle();
bundle.putString("mykey","abc"); 
bundle.putString("mykey2","abc"); // Put anything what you want

Fragment fragment = new Fragment();
fragment2.setArguments(bundle);

getFragmentManager()
  .beginTransaction()
  .replace(R.id.content, fragment2)
  .commit();

Bundle bundle = this.getArguments(); // in your fragment oncreate

if(bundle != null){
  String mykey = bundle.getString("mykey");
  String mykey2 = bundle.getString("mykey2");
  }

I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:

At web.config file, add the requestTimeout attribute at aspNetCore node.

<system.webServer>
  <aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>

In this example, I'm setting the value for 10 minutes.

My solution: Because all others did not work for me. I deleted the symlinks at C:\ProgramData\Oracle\Java\javapath. this makes eclipse to run with the jre declared in the PATH. This is better for me because I want to develop Java with the JRE I chose, not the system JRE. Often you want to develop with older versions and such

Have you tried:

eval $cmd

For the follow-on question of how to escape * since it has special meaning when it's naked or in double quoted strings: use single quotes.

MYSQL='mysql AMORE -u username -ppassword -h localhost -e'
QUERY="SELECT "'*'" FROM amoreconfig" ;# <-- "double"'single'"double"
eval $MYSQL "'$QUERY'"

Bonus: It also reads nice: eval mysql query ;-)

Alternatively you can directly jump into data directory and check for combined size of v3.myd, v3. myi and v3. frm files (for myisam) or v3.idb & v3.frm (for innodb).

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

Passable for getting multiple values with scanf()

int r,m,v,i,e,k;

scanf("%d%d%d%d%d%d",&r,&m,&v,&i,&e,&k);

Quick answer

On src, you can always specify files to ignore using "!".

Example (you want to exclude all *.min.js files on your js folder and subfolder:

gulp.src(['js/**/*.js', '!js/**/*.min.js'])

You can do it as well for individual files.

Expanded answer:

Extracted from gulp documentation:

gulp.src(globs[, options])

Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.

glob refers to node-glob syntax or it can be a direct file path.

So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.

On minimatch documentation, they point out the following:

if the pattern starts with a ! character, then it is negated.

And that is why using ! symbol will exclude files / directories from a gulp task

For this particular problem, why not store up your various results in variables and then when the last of your thread is processed you can print in whatever format you want. This is especially useful if you are gonna be using your work history in other projects.

If you use rs.next() you will move the cursor, than you should to move first() why don't check using first() directly?

    public void fetchData(ResultSet res, JTable table) throws SQLException{     
    ResultSetMetaData metaData = res.getMetaData();
    int fieldsCount = metaData.getColumnCount();
    for (int i = 1; i <= fieldsCount; i++)
        ((DefaultTableModel) table.getModel()).addColumn(metaData.getColumnLabel(i));
    if (!res.first())
        JOptionPane.showMessageDialog(rootPane, "no data!");
    else
        do {
            Vector<Object> v = new Vector<Object>();
            for (int i = 1; i <= fieldsCount; i++)              
                v.addElement(res.getObject(i));         
            ((DefaultTableModel) table.getModel()).addRow(v);
        } while (res.next());
        res.close();
}

This is one way to accomplish this using PowerShell:

<#
.SYNOPSIS
Restores (applies) a previously saved stash based on full or partial stash name.

.DESCRIPTION
Restores (applies) a previously saved stash based on full or partial stash name and then optionally drops the stash. Can be used regardless of whether "git stash save" was done or just "git stash". If no stash matches a message is given. If multiple stashes match a message is given along with matching stash info.

.PARAMETER message
A full or partial stash message name (see right side output of "git stash list"). Can also be "@stash{N}" where N is 0 based stash index.

.PARAMETER drop
If -drop is specified, the matching stash is dropped after being applied.

.EXAMPLE
Restore-Stash "Readme change"
Apply-Stash MyStashName
Apply-Stash MyStashName -drop
Apply-Stash "stash@{0}"
#>
function Restore-Stash  {
    [CmdletBinding()]
    [Alias("Apply-Stash")]
    PARAM (
        [Parameter(Mandatory=$true)] $message,         
        [switch]$drop
    )

    $stashId = $null

    if ($message -match "stash@{") {
        $stashId = $message
    }

    if (!$stashId) {
        $matches = git stash list | Where-Object { $_ -match $message }

        if (!$matches) {
            Write-Warning "No stashes found with message matching '$message' - check git stash list"
            return
        }

        if ($matches.Count -gt 1) {
            Write-Warning "Found $($matches.Count) matches for '$message'. Refine message or pass 'stash{@N}' to this function or git stash apply"
            return $matches
        }

        $parts = $matches -split ':'
        $stashId = $parts[0]
    }

    git stash apply ''$stashId''

    if ($drop) {
        git stash drop ''$stashId''
    }
}

Using the C++ API, the function name has slightly changed and it writes now:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, CV_BGR2GRAY);

The main difficulties are that the function is in the imgproc module (not in the core), and by default cv::Mat are in the Blue Green Red (BGR) order instead of the more common RGB.

OpenCV 3

Starting with OpenCV 3.0, there is yet another convention. Conversion codes are embedded in the namespace cv:: and are prefixed with COLOR. So, the example becomes then:

#include <opencv2/imgproc/imgproc.hpp>

cv::Mat greyMat, colorMat;
cv::cvtColor(colorMat, greyMat, cv::COLOR_BGR2GRAY);

As far as I have seen, the included file path hasn't changed (this is not a typo).

           Toast.makeText(context, "GPS permission allows us to access location data. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
       } else {
           ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_CODE);
       }
   }
   
   private boolean checkPermission() {
       int result = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION);
       if (result == PackageManager.PERMISSION_GRANTED) {
           return true;
       } else {
           return false;
       }
   }
   

Another easier way to print the whole string is to call values on the dataframe.

df = pd.DataFrame({'one' : ['one', 'two', 
      'This is very long string very long string very long string veryvery long string']})

print(df.values)

The Output will be

[['one']
 ['two']
 ['This is very long string very long string very long string veryvery long string']]

This may have changed since the question was asked, but there is a difference between stopping an instance and terminating an instance.

If your instance is EBS-based, it can be stopped. It will remain in your account, but you will not be charged for it (you will continue to be charged for EBS storage associated with the instance and unused Elastic IP addresses). You can re-start the instance at any time.

If the instance is terminated, it will be deleted from your account. You’ll be charged for any remaining EBS volumes, but by default the associated EBS volume will be deleted. This can be configured when you create the instance using the command-line EC2 API Tools.

If you have Java 7 so include the below following snippet within your app-level build.gradle :

compileOptions {

    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7

}

Without setting the type attribute, you could also return false from your OnClick handler, and declare the onclick attribute as onclick="return onBtnClick(event)".

Simply do:

mkdir /path/to/your/potentially/existing/folder

mkdir will throw an error if the folder already exists. To ignore the errors write:

mkdir -p /path/to/your/potentially/existing/folder

No need to do any checking or anything like that.

For reference:

-p, --parents no error if existing, make parent directories as needed http://man7.org/linux/man-pages/man1/mkdir.1.html

It's important to note, that NULL doesn't equal NULL.

NULL is not a value, and therefore cannot be compared to another value.

where x is null checks whether x is a null value.

where x = null is checking whether x equals NULL, which will never be true

I found this solution similar to the original problem

<?php

$test_array = array (
  'bla' => 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),
);

class NoSimpleXMLElement extends SimpleXMLElement {
 public function addChild($name,$value) {
  parent::addChild($value,$name);
 }
}
$xml = new NoSimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();

Try:

if($("option[value='parcel']").is(":checked"))
   $('#row_dim').show();

Or even:

$(function() {
    $('#type').change(function(){
        $('#row_dim')[ ($("option[value='parcel']").is(":checked"))? "show" : "hide" ]();  
    });
});

This is my solution which perfectly works starting from API 15. This solution keeps all default button click effects, like material RippleEffect. I have not tested it on lower APIs, but it should work.

All you need to do, is:

1) Create a style which changes only colorAccent:

<style name="Facebook.Button" parent="ThemeOverlay.AppCompat">
    <item name="colorAccent">@color/com_facebook_blue</item>
</style>

I recommend using ThemeOverlay.AppCompat or your main AppTheme as parent, to keep the rest of your styles.

2) Add these two lines to your button widget:

style="@style/Widget.AppCompat.Button.Colored"
android:theme="@style/Facebook.Button"

Sometimes your new colorAccent isn't showing in Android Studio Preview, but when you launch your app on the phone, the color will be changed.

Sample Button widget

<Button
    android:id="@+id/sign_in_with_facebook"
    style="@style/Widget.AppCompat.Button.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/sign_in_facebook"
    android:textColor="@android:color/white"
    android:theme="@style/Facebook.Button" />

To add to rcs' answer, if you want to use position_dodge() with geom_bar() when x is a POSIX.ct date, you must multiply the width by 86400, e.g.,

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
 geom_bar(position = "dodge", stat = 'identity') +
 geom_text(aes(label=Number), position=position_dodge(width=0.9*86400), vjust=-0.25)

I'm turning my comment to an answer, so it can be accepted and this question no longer remains unanswered.

The most likely cause of this is a malformed response, which includes characters before the initial <?xml …>. So please have a look at the document as transferred over HTTP, and fix this on the server side.

VERY SIMPLE FIX

1. Go to your app directory
2. Start SimpleHTTPServer

In the terminal

$ cd yourAngularApp
~/yourAngularApp $ python -m SimpleHTTPServer

Now, go to localhost:8000 in your browser and the page will show

^{More precise explanation of the CSS in kendo451's answer.}

There's another way to get a fancy-hacky inner shadow illusion,
which I'll explain in three simple steps. Say we have this HTML:

<h1>Get this</h1>

and this CSS:

h1 {
  color: black;
  background-color: #cc8100;
}

Step 1

Let's start by making the text transparent:

h1 {
  color: transparent;
  background-color: #cc8100;
}

Step 2

Now, we crop that background to the shape of the text:

h1 {
  color: transparent;
  background-color: #cc8100;
  background-clip: text;
}

Step 3

Now, the magic: we'll put a blurred text-shadow, which will be in front of the background, thus giving the impression of an inner shadow!

h1 {
  color: transparent;
  background-color: #cc8100;
  background-clip: text;
  text-shadow: 0px 2px 5px #f9c800;
}

See the final result.

Downsides?

• Only works in Webkit (background-clip can't be text).
• Multiple shadows? Don't even think.
• You get an outer glow too.

The lexically scoped integer pragma forces Perl to use integer arithmetic in its scope:

print 3.0/2.1 . "\n";    # => 1.42857142857143
{
  use integer;
  print 3.0/2.1 . "\n";  # => 1
}
print 3.0/2.1 . "\n";    # => 1.42857142857143

If your delimiter is only characters, you can use strtok, which seems to be more fit here. Note that you must use it with a while loop to achieve the effects.

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

I wanted to compare the method using substring and the method using slice from Base33 and user113716 respectively, to do that I wrote some code

also have a look at this performance comparison, substring, slice

The code I used creates huge strings and inserts the string "bar " multiple times into the huge string

     * @param {number} delCount An integer indicating the number of old chars to remove.

     * @return {string} A new string with the spliced substring.

    String.prototype.splice = function (start, delCount, newSubStr) {
        return this.slice(0, start) + newSubStr + this.slice(start + Math.abs(delCount));
    };
}

String.prototype.splice = function (idx, rem, str) {
    return this.slice(0, idx) + str + this.slice(idx + Math.abs(rem));
};


String.prototype.insert = function (index, string) {
    if (index > 0)

};

                )

        }
    }
}

The general difference in performance is marginal at best and both methods work just fine (even on strings of length ~~ 12000000)

The best solution for me is the custom pipe from @Kamalakar but with a slight modification to allow passing the format:

import { Pipe, PipeTransform} from '@angular/core';
import { DatePipe } from '@angular/common';

@Pipe({
    name: 'dateFormat'
  })
  export class DateFormatPipe extends DatePipe implements PipeTransform {
    transform(value: any, format: any): any {
       return super.transform(value, format);
    }
  }

And then called as:

console.log('Formatted date:', this._dateFormatPipe.transform(new Date(), 'MMM/dd/yyyy'));

[What you have is just an object, not a "json-object". JSON is a textual notation. What you've quoted is JavaScript code using an array initializer and an object initializer (aka, "object literal syntax").]

If you can rely on having ECMAScript5 features available, you can use the Object.keys function to get an array of the keys (property names) in an object. All modern browsers have Object.keys (including IE9+).

Object.keys(jsonData).forEach(function(key) {
    var value = jsonData[key];
    // ...
});

The rest of this answer was written in 2011. In today's world, A) You don't need to polyfill this unless you need to support IE8 or earlier (!), and B) If you did, you wouldn't do it with a one-off you wrote yourself or grabbed from an SO answer (and probably shouldn't have in 2011, either). You'd use a curated polyfill, possibly from es5-shim or via a transpiler like Babel that can be configured to include polyfills (which may come from es5-shim).

Here's the rest of the answer from 2011:

Note that older browsers won't have it. If not, this is one of the ones you can supply yourself:

if (typeof Object.keys !== "function") {
    (function() {
        var hasOwn = Object.prototype.hasOwnProperty;
        Object.keys = Object_keys;
        function Object_keys(obj) {
            var keys = [], name;
            for (name in obj) {
                if (hasOwn.call(obj, name)) {
                    keys.push(name);
                }
            }
            return keys;
        }
    })();
}

That uses a for..in loop (more info here) to loop through all of the property names the object has, and uses Object.prototype.hasOwnProperty to check that the property is owned directly by the object rather than being inherited.

(I could have done it without the self-executing function, but I prefer my functions to have names, and to be compatible with IE you can't use named function expressions [well, not without great care]. So the self-executing function is there to avoid having the function declaration create a global symbol.)

For those who prefer a bit more practical learning, select the segue in dock, open the attribute inspector and switch between different kinds of segues (dropdown "Kind"). This will reveal options specific for each of them: for example you can see that "present modally" allows you to choose a transition type etc.

Then apart from these 4, we have

foldByKey which is same as reduceByKey but with a user defined Zero Value.

AggregateByKey takes 3 parameters as input and uses 2 functions for merging(one for merging on same partitions and another to merge values across partition. The first parameter is ZeroValue)

whereas

ReduceBykey takes 1 parameter only which is a function for merging.

CombineByKey takes 3 parameter and all 3 are functions. Similar to aggregateBykey except it can have a function for ZeroValue.

GroupByKey takes no parameter and groups everything. Also, it is an overhead for data transfer across partitions.

ES6 modules support in Node.js is fairly recent; even in the bleeding-edge versions, it is still experimental. With Node.js 10, you can start Node.js with the --experimental-modules flag, and it will likely work.

To import on older Node.js versions - or standard Node.js 10 - use CommonJS syntax:

const fs = require('fs');

Most of answers are perfect here, but when I landed here for my particular problem, I have to upload binary file (XLSX spread sheet) using POST method, I see one thing missing, i.e. usually its not just file you load, you may have more form data elements, like comment to file or tags to file etc as was my case. Hence, I would like to add it here as it was my use case, so that it could help others.

curl -POST -F comment=mycomment -F file_type=XLSX -F file_data=@/your/path/to/file.XLSX http://yourhost.example.com/api/example_url

Code which disable chrome extensions for ones, who uses DesiredCapabilities to set browser flags :

desired_capabilities['chromeOptions'] = {
    "args": ["--disable-extensions"],
    "extensions": []
}
webdriver.Chrome(desired_capabilities=desired_capabilities)

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

I've been happily using pympler for such tasks. It's compatible with many versions of Python -- the asizeof module in particular goes back to 2.2!

For example, using hughdbrown's example but with from pympler import asizeof at the start and print asizeof.asizeof(v) at the end, I see (system Python 2.5 on MacOSX 10.5):

$ python pymp.py 
set 120
unicode 32
tuple 32
int 16
decimal 152
float 16
list 40
object 0
dict 144
str 32

Clearly there is some approximation here, but I've found it very useful for footprint analysis and tuning.

Another way of achieving this horizontal and vertical centering is:

.Absolute-Center {
  margin: auto;
  position: absolute;
  top: 0; left: 0; bottom: 0; right: 0;
}

There is a setting in the IE options that controls whether it should open new links in an existing window or in a new window. I'm not sure if you can control it from the command line but maybe changing this option would be enough for you.

In IE7 it looks like the option is "Reuse windows for launching shortcuts (when tabbed browsing is disabled)".

Here is improvement for icova's answer. It also groups inputs by name.

    var name = allRequiredCheckboxes[i].name;
    checkboxNames.push(name);
  }

  checkboxNames = checkboxNames.reduce(function(p, c) {
    if (p.indexOf(c) < 0) p.push(c);
    return p;
  }, []);

  for (var i in checkboxNames){
    !function(){
      var name = checkboxNames[i];
      var checkboxes = $('input[name="' + name + '"]');
      checkboxes.change(function(){

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

It's worth pointing out that if you have an Excel 2007 (xlsm) file, then you can simply save it as an Excel 2003 (xls) file and use the methods outlined in other answers.

int val1 = [textBox1.text integerValue];
int val2 = [textBox2.text integerValue];

int resultValue = val1 * val2;

textBox3.text = [NSString stringWithFormat: @"%d", resultValue];

Try simply this:

Swift 4

// Call the method
(UIApplication.shared.delegate as? AppDelegate)?.whateverWillOccur()

where in your AppDelegate:

// MARK: - Whatever
func whateverWillOccur() {

    // Your code here.

}

Potatoswatter's answer is all right, but I prefer to use find or lower_bound instead. lower_bound is especially useful because the iterator returned can subsequently be used for a hinted insertion, should you wish to insert something with the same key.

map<K, V>::iterator iter(my_map.lower_bound(key));
if (iter == my_map.end() || key < iter->first) {    // not found
    // ...
    my_map.insert(iter, make_pair(key, value));     // hinted insertion
} else {
    // ... use iter->second here
}

Yes, a UITextView is what you're looking for. You'll have to deal with some things differently (like the return key) but you can add text to it, and it will allow you to scroll up and down if there's too much text inside.

This link has info about making a screen to enter data:

create a data entry screen

Assuming join wasn't designed that way (which it is, as ATOzTOA pointed out), and it only took two parameters, you could still use the built-in reduce:

>>> reduce(os.path.join,["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt'

Same output like:

>>> os.path.join(*["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt' 

Just for completeness and educational reasons (and for other situations where * doesn't work).

Hint for Python 3

reduce was moved to the functools module.

Remember jQuery is a JavaScript library, i.e. like an extension. That means you can use both jQuery and JavaScript in the same function (restrictions apply).

You declare/create variables in the same way as in Javascript: var example;

However, you can use jQuery for assigning values to variables:

var example = $("#unique_product_code").html();

Instead of pure JavaScript:

var example = document.getElementById("unique_product_code").innerHTML;

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

.left {
  float: left;
  width: 125px;
  text-align: right;
  margin: 2px 10px;
  display: inline;
}

.right {
  float: left;
  text-align: left;
  margin: 2px 10px;
  display: inline;
}

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

As already stated there is nothing you can do except restore from a backup. At least now you will have learned to always wrap statements in a transaction to see what happens before you decide to commit. Also, if you don't have a backup of your database this will also teach you to make regular backups of your database.

While we haven't been much help for your imediate problem...hopefully these answers will ensure you don't run into this problem again in the future.

Semantically you are asking "insert Competitors where doesn't already exist":

INSERT Competitors (cName)
SELECT DISTINCT Name
FROM CompResults cr
WHERE
   NOT EXISTS (SELECT * FROM Competitors c
              WHERE cr.Name = c.cName)

The first option's text will always display as default title.

   <select>
        <option value ="">What is the name of your city?</option>
        <option value ="sydney">Sydney</option>
        <option value ="melbourne">Melbourne</option>
        <option value ="cromwell">Cromwell</option>
        <option value ="queenstown">Queenstown</option>
   </select>

The syntax for REPLACE:

REPLACE (string_expression,string_pattern,string_replacement)

So that the SQL you need should be:

UPDATE [DataTable] SET [ColumnValue] = REPLACE([ColumnValue], 'domain2', 'domain1')

I also hit this error…

The installation msi will try to create a new task in the Windows Task scheduler to remind you to give customer feedback. This install step executes regardless of whether you do or do not click the check box to participate in customer feedback. In many corporate environments (including mine) creating new windows tasks is denied to all but domain administrators. As a result, running as a local admin is not sufficient and the entire installation fails when adding the task returns “access denied”. This shows up in the install log as a 1603.

The only workaround we could find was to manually pull all the files out of the msi, remove the “add schedule task” from the install script, and then create a new msi. After that one line change, it worked fine.

The POSIX specification for find says:

-mtimen The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

Interestingly, the description of find does not further specify 'initialization time'. It is probably, though, the time when find is initialized (run).

In the descriptions, wherever n is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a plus ( '+' ) or minus-sign ( '-' ) sign, as follows:

+n More than n.
  n Exactly n.
-n Less than n.

At the given time (2014-09-01 00:53:44 -4:00, where I'm deducing that AST is Atlantic Standard Time, and therefore the time zone offset from UTC is -4:00 in ISO 8601 but +4:00 in ISO 9945 (POSIX), but it doesn't matter all that much):

1409547224 = 2014-09-01 00:53:44 -04:00
1409457540 = 2014-08-30 23:59:00 -04:00

so:

1409547224 - 1409457540 = 89684
89684 / 86400 = 1

Even if the 'seconds since the epoch' values are wrong, the relative values are correct (for some time zone somewhere in the world, they are correct).

The n value calculated for the 2014-08-30 log file therefore is exactly 1 (the calculation is done with integer arithmetic), and the +1 rejects it because it is strictly a > 1 comparison (and not >= 1).

XmlDocument.Attributes perhaps? (Which has a method GetNamedItem that will presumably do what you want, although I've always just iterated the attribute collection)

In OO terms, a monad is a fluent container.

The minimum requirement is a definition of class <A> Something that supports a constructor Something(A a) and at least one method Something<B> flatMap(Function<A, Something<B>>)

Arguably, it also counts if your monad class has any methods with signature Something<B> work() which preserves the class's rules -- the compiler bakes in flatMap at compile time.

Why is a monad useful? Because it is a container that allows chain-able operations that preserve semantics. For example, Optional<?> preserves the semantics of isPresent for Optional<String>, Optional<Integer>, Optional<MyClass>, etc.

As a rough example,

Something<Integer> i = new Something("a")
  .flatMap(doOneThing)
  .flatMap(doAnother)
  .flatMap(toInt)

Note we start with a string and end with an integer. Pretty cool.

In OO, it might take a little hand-waving, but any method on Something that returns another subclass of Something meets the criterion of a container function that returns a container of the original type.

That's how you preserve semantics -- i.e. the container's meaning and operations don't change, they just wrap and enhance the object inside the container.

To ignore some folder from eslint rules we could create the file .eslintignore in root directory and add there the path to the folder we want omit (the same way as for .gitignore).

Here is the example from the ESLint docs on Ignoring Files and Directories:

# path/to/project/root/.eslintignore
# /node_modules/* and /bower_components/* in the project root are ignored by default

# Ignore built files except build/index.js
build/*
!build/index.js

The code snippet:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
    var deferred = $q.defer();
    deferred.resolve('Remote call result');
    return deferred.promise;
});

Can be written in a more concise form:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.returnValue(function() {
    return $q.resolve('Remote call result');
});

you can also use extractedData=data([:,1],[:,9])

I'm currently experimenting with canvas and pixels... I'm finding this logic works out for me better.

1. Use this to calculate the grey-ness ( luma ? )
2. but with both the existing value and the new 'tint' value
3. calculate the difference ( I found I did not need to multiply )

4. add to offset the 'tint' value

   var grey =  (r + g + b) / 3;    
   var grey2 = (new_r + new_g + new_b) / 3;
   
   var dr =  grey - grey2 * 1;    
   var dg =  grey - grey2 * 1    
   var db =  grey - grey2 * 1;  
   
   tint_r = new_r + dr;    
   tint_g = new_g + dg;   
   tint_b = new_b _ db;
   

or something like that...

I also posted an answer to a related question here.

From the "Updating Chosen Dynamically" section in the docs: You need to trigger the 'chosen:updated' event on the field

$(document).ready(function() {

    $('select').chosen();

    $('button').click(function() {
        $('select').val(2);
        $('select').trigger("chosen:updated");
    });

});

NOTE: versions prior to 1.0 used the following:

$('select').trigger("liszt:updated");

Date#parse is deprecated . The alternative is :

java.text.DateFormat#parse 

thereFore :

 new SimpleDateFormat("E MMM dd H:m:s z yyyy", Locale.ARABIC).parse(testDate)

Note that SimpleDateFormat is an implementation of DateFormat

When you want to create an external_table, all field's name must be written in UPPERCASE.

Done.

There's nothing missing. Float was designed for the case where you want an image (for example) to sit beside several paragraphs of text, so the text flows around the image. That wouldn't happen if the text "stretched" the container. Your first paragraph would end, and then your next paragraph would begin under the image (possibly several hundred pixels below).

And that's why you're getting the result you are.

It should be either

document.getElementById("test").style.display = "none";

or

document.getElementById("test").style.visibility = "hidden";

Second option will display some blank space where the form was initially present , where as the first option doesn't

I got the same error.

I was refering a VS2010 DLL in a VS2012 project.

You can try the following VBA code to export Macro contents directly without converting them to VBA first. Unlike Tables, Forms, Reports, and Modules, the Macros are in a container called Scripts. But they are there and can be exported and imported using SaveAsText and LoadFromText

Option Compare Database

Option Explicit

Public Sub ExportDatabaseObjects()
On Error GoTo Err_ExportDatabaseObjects

    Dim db As Database
    Dim d As Document
    Dim c As Container
    Dim sExportLocation As String

    Set db = CurrentDb()

    sExportLocation = "C:\SomeFolder\"
    Set c = db.Containers("Scripts")
    For Each d In c.Documents
        Application.SaveAsText acMacro, d.Name, sExportLocation & "Macro_" & d.Name & ".txt"
    Next d

An alternative object to use is as follows:

  For Each obj In Access.Application.CurrentProject.AllMacros
    Access.Application.SaveAsText acMacro, obj.Name, strFilePath & "\Macro_" & obj.Name & ".txt"
  Next

This answer comes a little late, but it completes the response.

In order to avoid a field from an entity to be persisted in DB one can use one of the two mechanisms:

@Transient - the JPA annotation marking a field as not persistable

transient keyword in java. Beware - using this keyword, will prevent the field to be used with any serialization mechanism from java. So, if the field must be serialized you'd better use just the @Transient annotation.

Just add bind(this) in your setTimeout function it will start working

setTimeout(function() {
       this.edited = false;
       console.log(this.edited);
   }.bind(this), 3000);

and in HTML change

<div *ngIf="edited==true" class="alert alert-success alert-dismissible fade in" role="alert">
        <strong>List Saved!</strong> Your changes has been saved.
</div>

To

<div *ngIf="edited" class="alert alert-success alert-dismissible fade in" role="alert">
        <strong>List Saved!</strong> Your changes has been saved.
</div>

Alternatively, if you are using ui-router:

index.html

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <title ng-bind="$state.current.data.title || 'App'">App</title>

Routing

$stateProvider
  .state('home', {
      url: '/',
      templateUrl: 'views/home.html',
      data: {
        title: 'Welcome Home.'
      }
  }

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

Two different ways I got this working.

Option 1: Add these 3 <script> tags to your .html file, just before the closing </body> tag:

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>

Option 2 (Option 2 works with Angular, not sure about other frameworks)

Step 1: Install the 3 libraries using NPM:

npm install bootstrap --save

npm install popper.js --save

npm install jquery --save

Step 2: Update the script: array(s) in your angular.json file like this:

"scripts": ["node_modules/jquery/dist/jquery.min.js", "node_modules/popper.js/dist/umd/popper.min.js", "node_modules/bootstrap/dist/js/bootstrap.min.js"]

Based on the very helpful answer by joran I was able to come up with this solution for a stable color scale for a boolean factor (TRUE, FALSE).

boolColors <- as.character(c("TRUE"="#5aae61", "FALSE"="#7b3294"))
boolScale <- scale_colour_manual(name="myboolean", values=boolColors)

ggplot(myDataFrame, aes(date, duration)) + 
  geom_point(aes(colour = myboolean)) +
  boolScale

Since ColorBrewer isn't very helpful with binary color scales, the two needed colors are defined manually.

Here myboolean is the name of the column in myDataFrame holding the TRUE/FALSE factor. date and duration are the column names to be mapped to the x and y axis of the plot in this example.

how about just getting the length of char in your EditText and display it?

something along the line of

tv.setText(s.length() + " / " + String.valueOf(charCounts));

AJAX is getting data from the server using Javascript and XML in an asynchronous fashion. Unless you want to download the colour code from the server, that's not what you're really aiming for!

But otherwise you can set the CSS background with Javascript. If you're using a framework like jQuery, it'll be something like this:

$('body').css('background', '#ccc');

Otherwise, this should work:

document.body.style.background = "#ccc";

BULK INSERT dbo.temp 

FROM 'c:\temp\file.txt' --- path file in db server 

WITH 

  (
     ROWTERMINATOR ='\n'
  )

it work for me but save as by editplus to ansi encoding for multilanguage

If you're interested in creating a new dict without using intermediary storage: (this is faster, and in my opinion, cleaner than using dict.items())

dic2 = dict(dic0, **dic1)

Or if you're happy to use one of the existing dicts:

dic0.update(dic1)

The thought process here is that you spend most of your time in development. When in development, you create a feature branch (off of development), complete the feature, and then merge back into development. This can then be added to the final production version by merging into production.

See A Successful Git Branching Model for more detail on this approach.

            THEN ID

To enable zoom controls in a WebView, add the following line:

webView.getSettings().setBuiltInZoomControls(true);

With this line of code, you get the zoom enabled in your WebView, if you want to remove the zoom in and zoom out buttons provided, add the following line of code:

webView.getSettings().setDisplayZoomControls(false);

If you want to have that directory as your default, simply add a cd statement to your ~/.profile file.

What I tend to do is use that method to set my usual directory, plus define aliases for my common cases as well:

alias tom="cd /users/tom"

or your equivalent. This lets me change directories very fast.

Since state isn't tightly coupled with component instance in functional components, previous state cannot be reached in useEffect without saving it first, for instance, with useRef. This also means that state update was possibly incorrectly implemented in wrong place because previous state is available inside setState updater function.

This is a good use case for useReducer which provides Redux-like store and allows to implement respective pattern. State updates are performed explicitly, so there's no need to figure out which state property is updated; this is already clear from dispatched action.

Here's an example what it may look like:

function reducer({ sendAmount, receiveAmount, rate }, action) {
  switch (action.type) {
    case "sendAmount":
      sendAmount = action.payload;
      return {
        sendAmount,
        receiveAmount: sendAmount * rate,
        rate
      };
    case "receiveAmount":
      receiveAmount = action.payload;
      return {
        sendAmount: receiveAmount / rate,
        receiveAmount,
        rate
      };
    case "rate":
      rate = action.payload;
      return {
        sendAmount: receiveAmount ? receiveAmount / rate : sendAmount,
        receiveAmount: sendAmount ? sendAmount * rate : receiveAmount,
        rate
      };
    default:
      throw new Error();
  }
}

function handleChange(e) {
  const { name, value } = e.target;
  dispatch({
    type: name,
    payload: value
  });
}

...
const [state, dispatch] = useReducer(reducer, {
  rate: 2,
  sendAmount: 0,
  receiveAmount: 0
});
...

In my case I was trying to connect to a remote mysql server on cent OS. After going through a lot of solutions (granting all privileges, removing ip bindings,enabling networking) problem was still not getting solved.

As it turned out, while looking into various solutions,I came across iptables, which made me realize mysql port 3306 was not accepting connections.

Here is a small note on how I checked and resolved this issue.

• Checking if port is accepting connections:

  telnet (mysql server ip) [portNo]

• Adding ip table rule to allow connections on the port:

  iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT

• Would not recommend this for production environment, but if your iptables are not configured properly, adding the rules might not still solve the issue. In that case following should be done:

  service iptables stop

Hope this helps.

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspet ratio */
  min-width: 100%;
  min-height: 100%;
}

This converts a BitmapDrawable to a Bitmap.

Drawable d = ImagesArrayList.get(0);  
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();

I had the same problem, the first thing that came to mind was repositories. So I checked the build.gradle file for the whole project and added the following code, then synchronized the gradle with project and problem was solved!

allprojects {
    repositories {
        jcenter()
    }
}

Download Git on Msys. Then:

git clone git://project.url.here

Date format can also be set by using below query :-

alter SESSION set NLS_DATE_FORMAT = 'date_format'

e.g. : alter SESSION set NLS_DATE_FORMAT = 'DD-MM-YYYY HH24:MI:SS'

This command worked for me:

adb shell pm clear packageName

Arrays in Java are of fixed size that is specified when they are declared. To increase the size of the array you have to create a new array with a larger size and copy all of the old values into the new array.

ex:

char[] copyFrom  = { 'a', 'b', 'c', 'd', 'e' };
char[] copyTo    = new char[7];

System.out.println(Arrays.toString(copyFrom));
System.arraycopy(copyFrom, 0, copyTo, 0, copyFrom.length);
System.out.println(Arrays.toString(copyTo));

Alternatively you could use a dynamic data structure like a List.

I had the same issue I solved it like that:

axios.delete(url, {data:{username:"user", password:"pass"}, headers:{Authorization: "token"}})

jQuery takes care of this for you. The first argument to your .each() callback function is the index of the current iteration of the loop. The second being the current matched DOM element So:

$('#list option').each(function(index, element){
  alert("Iteration: " + index)
});

try overflow hidden on the thing you don't want to scroll while touch event is happening. e.g set overflow hidden on Start and set it back to auto on end.

Did you try it ? I'd be interested to know if this would work.

document.addEventListener('ontouchstart', function(e) {
    document.body.style.overflow = "hidden";
}, false);

document.addEventListener('ontouchmove', function(e) {
    document.body.style.overflow = "auto";
}, false);

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):

public class ListViewDemoActivity extends AppCompatActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;
    private ListView mListView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_list_view_demo);

        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }

        adapter=new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }

    protected ListView getListView() {
        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }
        return mListView;
    }

    protected void setListAdapter(ListAdapter adapter) {
        getListView().setAdapter(adapter);
    }

    protected ListAdapter getListAdapter() {
        ListAdapter adapter = getListView().getAdapter();
        if (adapter instanceof HeaderViewListAdapter) {
            return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
        } else {
            return adapter;
        }
    }
}

And in you layout instead of using android:id="@android:id/list" you can use android:id="@+id/listDemo"

So now you can have a ListView inside a normal AppCompatActivity.

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

        <input type="file" id="picfile" name="picf" />
       <input type="text" id="txtName" style="width: 144px;" />
 $("#btncatsave").click(function () {
var Name = $("#txtName").val();
var formData = new FormData();
var totalFiles = document.getElementById("picfile").files.length;

                    var file = document.getElementById("picfile").files[0];
                    formData.append("FileUpload", file);
                    formData.append("Name", Name);

$.ajax({
                    type: "POST",
                    url: '/Category_Subcategory/Save_Category',
                    data: formData,
                    dataType: 'json',
                    contentType: false,
                    processData: false,
                    success: function (msg) {

                                 alert(msg);

                    },
                    error: function (error) {
                        alert("errror");
                    }
                });

});

 [HttpPost]
    public ActionResult Save_Category()
    {
      string Name=Request.Form[1]; 
      if (Request.Files.Count > 0)

Returning b is returning a function object. In Javascript, functions are just objects, like any other object. If you find that not helpful, just replace the word "object" with "thing". You can return any object from a function. You can return a true/false value. An integer (1,2,3,4...). You can return a string. You can return a complex object with multiple properties. And you can return a function. a function is just a thing.

In your case, returning b returns the thing, the thing is a callable function. Returning b() returns the value returned by the callable function.

Consider this code:

function b() {
   return 42;
}

Using the above definition, return b(); returns the value 42. On the other hand return b; returns a function, that itself returns the value of 42. They are two different things.

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

As of python 3.2, using only standard library functions:

u_tm = datetime.datetime.utcfromtimestamp(0)
l_tm = datetime.datetime.fromtimestamp(0)
l_tz = datetime.timezone(l_tm - u_tm)

t = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=l_tz)
str(t)
'2009-07-10 18:44:59.193982-07:00'

Just need to use l_tm - u_tm or u_tm - l_tm depending whether you want to show as + or - hours from UTC. I am in MST, which is where the -07 comes from. Smarter code should be able to figure out which way to subtract.

And only need to calculate the local timezone once. That is not going to change. At least until you switch from/to Daylight time.

Found solution on the error page itself. Just needed to add requestValidationMode="2.0" in web.config

<system.web>
    <compilation debug="true" targetFramework="4.0" />
    <httpRuntime requestValidationMode="2.0" />
</system.web>

iOS 9 and later:

iOS 9 added a new class called NSBatchDeleteRequest that allows you to easily delete objects matching a predicate without having to load them all in to memory. Here's how you'd use it:

Swift 5

let fetchRequest: NSFetchRequest<NSFetchRequestResult> = NSFetchRequest(entityName: "Car")
let deleteRequest = NSBatchDeleteRequest(fetchRequest: fetchRequest)

do {
    try myPersistentStoreCoordinator.execute(deleteRequest, with: myContext)
} catch let error as NSError {
    // TODO: handle the error
}

Objective-C

NSFetchRequest *request = [[NSFetchRequest alloc] initWithEntityName:@"Car"];
NSBatchDeleteRequest *delete = [[NSBatchDeleteRequest alloc] initWithFetchRequest:request];

NSError *deleteError = nil;
[myPersistentStoreCoordinator executeRequest:delete withContext:myContext error:&deleteError];

More information about batch deletions can be found in the "What's New in Core Data" session from WWDC 2015 (starting at ~14:10).

iOS 8 and earlier:

Fetch 'em all and delete 'em all:

NSFetchRequest *allCars = [[NSFetchRequest alloc] init];
[allCars setEntity:[NSEntityDescription entityForName:@"Car" inManagedObjectContext:myContext]];
[allCars setIncludesPropertyValues:NO]; //only fetch the managedObjectID

NSError *error = nil;
NSArray *cars = [myContext executeFetchRequest:allCars error:&error];
[allCars release];
//error handling goes here
for (NSManagedObject *car in cars) {
  [myContext deleteObject:car];
}
NSError *saveError = nil;
[myContext save:&saveError];
//more error handling here

I have changed to your code with little modification will works well. Here is the code:

butangDonload.php

<?php
$file = "logo_ldg.png"; //Let say If I put the file name Bang.png
echo "<a href='download1.php?nama=".$file."'>download</a> ";
?>

download.php

<?php
$name= $_GET['nama'];

    header('Content-Description: File Transfer');
    header('Content-Type: application/force-download');
    header("Content-Disposition: attachment; filename=\"" . basename($name) . "\";");
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($name));
    ob_clean();
    flush();
    readfile("your_file_path/".$name); //showing the path to the server where the file is to be download
    exit;
?>

Here you need to show the path from where the file to be download. i.e. will just give the file name but need to give the file path for reading that file. So, it should be replaced by I have tested by using your code and modifying also will works.

<div class="container" style="width: 100%;">
    <div class="sidebar" style="width: 200px; float: left;">
        Sidebar
    </div>
    <div class="content" style="margin-left: 202px;">
        content 
    </div>
</div>

This will be cross browser compatible. Without the margin-left you will run into issues with content running all the way to the left if you content is longer than your sidebar.

Sku is an int, can't be defaulted to string "sku". Please check Optional URI Parameters and Default Values

You don't have that kind of control with a bare a tag. But you can hook up the tag's onclick handler to call window.open(...) with the right parameters. See here for examples: https://developer.mozilla.org/En/DOM/Window.open

I still don't think you can force window over tab directly though-- that depends on the browser and the user's settings.

If one wants to follow a more Reactive oriented style of programming, then definitely the concept of "Everything is a stream" comes into picture and hence, use Observables to deal with these streams as often as possible.

I would use your suggested code, but with a slight simplification:

KeyGenerator keyGen = KeyGenerator.getInstance("AES");
keyGen.init(256); // for example
SecretKey secretKey = keyGen.generateKey();

Let the provider select how it plans to obtain randomness - don't define something that may not be as good as what the provider has already selected.

This code example assumes (as Maarten points out below) that you've configured your java.security file to include your preferred provider at the top of the list. If you want to manually specify the provider, just call KeyGenerator.getInstance("AES", "providerName");.

For a truly secure key, you need to be using a hardware security module (HSM) to generate and protect the key. HSM manufacturers will typically supply a JCE provider that will do all the key generation for you, using the code above.

Use isinstance, nothing else:

if isinstance(x, pd.DataFrame):
    ... # do something

PEP8 says explicitly that isinstance is the preferred way to check types

No:  type(x) is pd.DataFrame
No:  type(x) == pd.DataFrame
Yes: isinstance(x, pd.DataFrame)

And don't even think about

if obj.__class__.__name__ = 'DataFrame':
    expect_problems_some_day()

isinstance handles inheritance (see What are the differences between type() and isinstance()?). For example, it will tell you if a variable is a string (either str or unicode), because they derive from basestring)

if isinstance(obj, basestring):
    i_am_string(obj)

Specifically for pandas DataFrame objects:

import pandas as pd
isinstance(var, pd.DataFrame)

df.T.iloc[-1]

df.T.tail(1)

pd.Series(df.values[:, -1], name=df.columns[-1])

//set height of html
$("html").css("height", screen.height);
//set width of html
$("html").css("width", screen.width);
//go to full screen mode
document.documentElement.webkitRequestFullscreen();

Yes. you can use SimpleDateFormat like this.

SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));

Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207

In a single database - yes:

USE your_database
SELECT name FROM sys.tables

Getting all tables across all databases - only with a hack.... see this SO question for several approaches how to do that: How do I list all tables in all databases in SQL Server in a single result set?

site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default.

There are standard locations:

• Unix (pure)¹: prefix/lib/pythonX.Y/site-packages
• Unix (non-pure): exec-prefix/lib/pythonX.Y/site-packages
• Windows: prefix\Lib\site-packages

¹ Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.

site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards.

Useful reading

• Installing Python Modules (for Python 2)
• Installing Python Modules (for Python 3)

1. Object* o; o = new Object();

2. Object* o = new Object();

Both these statement creates the object in the heap memory since you are creating the object using "new".

To be able to make the object creation happen in the stack, you need to follow this:

Object o;
Object *p = &o;

Yes, you can indeed. There are three ways of achieving this that I can think of.

1. Add inline styles to the elements.
2. create and append a new <style> element, and add the text to override this style to it.
3. Modify the css rule itself.

Notes:

1. is somewhat messy and adds to the parsing the browser needs to do to render.
2. perhaps my favourite method
3. Not cross-browser, some browsers like it done one way, others a different way, while the remainder just baulk at the idea.

I think the event.stopPropagation(); should be mentioned here as well. Add this to the Click function of your button.

Prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.

If you are returning a complex json object you need to modify you success function of your auto-complete as follows.

$.ajax({
    url: "/Employees/SearchEmployees",
    dataType: "json",
    data: {
        searchText: request.term
    },
    success: function (data) {
        response($.map(data.employees, function (item) {
            return {
                label: item.name,
                value: item.id
            };
        }));
    }
});

n=int(input())
pair = dict()

for i in range(0,n):
        word = input().split()
        key = word[0]
        value = word[1]
        pair[key]=value

print(pair)

This solution runs only one loop and has the minimun object to map numerals to roman letters

function RomantoNumeral(r){
  let result = 0,
      keys = {M:1000, D:500, C:100, L:50, C:100, L:50, X:10, V:5, I:1},
      order = Object.keys(keys),
      rom = Array.from(r) 

  rom.forEach((e, i)=>{
    if( i  < rom.length -1 && order.indexOf(e) > order.indexOf(rom[i+1])){
      result -= keys[e]
    } else {
      result +=keys[e]
    }
  })  
  return result
}

RomantoNumeral('MMDCCCXXXVII') #2837

In your app.js file:

.run(["$rootScope", "$state", function($rootScope, $state) {

      $rootScope.$on('$locationChangeStart', function(event, next, current) {
        if (!$rootScope.loggedUser == null) {
          $state.go('home');
        }    
      });
}])

The problem is that your code is creating a blank UIViewController, not a SecondViewController. You need to create an instance of your subclass, not a UIViewController,

func transition(Sender: UIButton!) {   
    let secondViewController:SecondViewController = SecondViewController()

    self.presentViewController(secondViewController, animated: true, completion: nil)

 }

If you've overridden init(nibName nibName: String!,bundle nibBundle: NSBundle!) in your SecondViewController class, then you need to change the code to,

let sec: SecondViewController = SecondViewController(nibName: nil, bundle: nil)

Variable definitions are meant to be used in tasks. But if you want to include them in tasks probably use the register directive. Like this:

- name: Define variable in task.
  shell: echo "http://www.my.url.com"
  register: url

- name: Download apache
  shell: wget {{ item }}
  with_items: url.stdout

You can also look at roles as a way of separating tasks depending on the different roles roles. This way you can have separate variables for each of one of your roles. For example you may have a url variable for apache1 and a separate url variable for the role apache2.

In android Oreo,notification app is done by using channels and NotificationHelper class.It should have a channel id and channel name.

First u have to create a NotificationHelper Class

public class NotificationHelper extends ContextWrapper {

private static final String EDMT_CHANNEL_ID="com.example.safna.notifier1.EDMTDEV";
private static final String EDMT_CHANNEL_NAME="EDMTDEV Channel";
private NotificationManager manager;

public  NotificationHelper(Context base)
{
    super(base);
    createChannels();
}
private void createChannels()
{
    NotificationChannel edmtChannel=new NotificationChannel(EDMT_CHANNEL_ID,EDMT_CHANNEL_NAME,NotificationManager.IMPORTANCE_DEFAULT);
    edmtChannel.enableLights(true);
    edmtChannel.enableVibration(true);
    edmtChannel.setLightColor(Color.GREEN);
    edmtChannel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);

    getManager().createNotificationChannel(edmtChannel);

}
public NotificationManager getManager()
{
   if (manager==null)
       manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
   return manager;

}
public NotificationCompat.Builder getEDMTChannelNotification(String title,String body)
{
    return new NotificationCompat.Builder(getApplicationContext(),EDMT_CHANNEL_ID)
            .setContentText(body)
            .setContentTitle(title)
            .setSmallIcon(R.mipmap.ic_launcher_round)
            .setAutoCancel(true);
    }
}

Create a button in activity xml file,then In the main activity

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    helper=new NotificationHelper(this);

    btnSend=(Button)findViewById(R.id.btnSend);

    btnSend.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String title="Title";
            String content="Content";
            Notification.Builder builder=helper.getEDMTChannelNotification(title,content);
            helper.getManager().notify(new Random().nextInt(),builder.build());
        }
    });

}

Then run ur project

Most other solutions here require that you create the table in advance/manually. This may not be practical in some cases (e.g., if you have a lot of columns in the destination table). So, the approach below may come handy.

Providing the path and column count of your csv file, you can use the following function to load your table to a temp table that will be named as target_table:

The top row is assumed to have the column names.

create or replace function data.load_csv_file
(
    target_table text,
    csv_path text,
    col_count integer
)

returns void as $$

declare

iter integer; -- dummy integer to iterate columns with
col text; -- variable to keep the column name at each iteration
col_first text; -- first column name, e.g., top left corner on a csv file or spreadsheet

begin
    create table temp_table ();

    -- add just enough number of columns
    for iter in 1..col_count
    loop
        execute format('alter table temp_table add column col_%s text;', iter);
    end loop;

    -- copy the data from csv file
    execute format('copy temp_table from %L with delimiter '','' quote ''"'' csv ', csv_path);

    iter := 1;
    col_first := (select col_1 from temp_table limit 1);

    -- update the column names based on the first row which has the column names
    for col in execute format('select unnest(string_to_array(trim(temp_table::text, ''()''), '','')) from temp_table where col_1 = %L', col_first)
    loop
        execute format('alter table temp_table rename column col_%s to %s', iter, col);
        iter := iter + 1;
    end loop;

    -- delete the columns row
    execute format('delete from temp_table where %s = %L', col_first, col_first);

    -- change the temp table name to the name given as parameter, if not blank
    if length(target_table) > 0 then
        execute format('alter table temp_table rename to %I', target_table);
    end if;

end;

Having seen a large amount of issues with bitmaps incorrectly scaling when converted to a BitmapDrawable, the general way to convert should be:

Drawable d = new BitmapDrawable(getResources(), bitmap);

Without the Resources reference, the bitmap may not render properly, even when scaled correctly. There are numerous questions on here which would be solved simply by using this method rather than a straight call with only the bitmap argument.

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

Or use a cast with split to uniform type of str

unique, counts = numpy.unique(str(a).split(), return_counts=True)

Add "babel-preset-react"

npm install babel-preset-react

and add "presets" option to babel-loader in your webpack.config.js

(or you can add it to your .babelrc or package.js: http://babeljs.io/docs/usage/babelrc/)

Here is an example webpack.config.js:

{ 
    test: /\.jsx?$/,         // Match both .js and .jsx files
    exclude: /node_modules/, 
    loader: "babel", 
    query:
      {
        presets:['react']
      }
}

Recently Babel 6 was released and there was a major change: https://babeljs.io/blog/2015/10/29/6.0.0

If you are using react 0.14, you should use ReactDOM.render() (from require('react-dom')) instead of React.render(): https://facebook.github.io/react/blog/#changelog

UPDATE 2018

Rule.query has already been deprecated in favour of Rule.options. Usage in webpack 4 is as follows:

npm install babel-loader babel-preset-react

Then in your webpack configuration (as an entry in the module.rules array in the module.exports object)

{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    use: [
      {
        loader: 'babel-loader',
        options: {
          presets: ['react']
        }
      }
    ],
  }

The way to do this without use of plugins is to make a subclass of google's OverlayView() method.

https://developers.google.com/maps/documentation/javascript/reference?hl=en#OverlayView

You make a custom function and apply it to the map.

function Label() { 
    this.setMap(g.map);
};

Now you prototype your subclass and add HTML nodes:

Label.prototype = new google.maps.OverlayView; //subclassing google's overlayView
Label.prototype.onAdd = function() {
        this.MySpecialDiv               = document.createElement('div');
        this.MySpecialDiv.className     = 'MyLabel';
        this.getPanes().overlayImage.appendChild(this.MySpecialDiv); //attach it to overlay panes so it behaves like markers

}

you also have to implement remove and draw functions as stated in the API docs, or this won't work.

Label.prototype.onRemove = function() {
... // remove your stuff and its events if any
}
Label.prototype.draw = function() {
      var position = this.getProjection().fromLatLngToDivPixel(this.get('position')); // translate map latLng coords into DOM px coords for css positioning
var pos = this.get('position');
            $('.myLabel')
            .css({
                'top'   : position.y + 'px',
                'left'  : position.x + 'px'
            })
        ;
}

That's the gist of it, you'll have to do some more work in your specific implementation.

There's actually a very little known class in the BCL for this purpose exactly: CommaDelimitedStringCollectionConverter. It serves as a middle ground of sorts between having a ConfigurationElementCollection (as in Richard's answer) and parsing the string yourself (as in Adam's answer).

For example, you could write the following configuration section:

public class MySection : ConfigurationSection
{
    [ConfigurationProperty("MyStrings")]
    [TypeConverter(typeof(CommaDelimitedStringCollectionConverter))]
    public CommaDelimitedStringCollection MyStrings
    {
        get { return (CommaDelimitedStringCollection)base["MyStrings"]; }
    }
}

You could then have an app.config that looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="foo" type="ConsoleApplication1.MySection, ConsoleApplication1"/>
  </configSections>
  <foo MyStrings="a,b,c,hello,world"/>
</configuration>

Finally, your code would look like this:

var section = (MySection)ConfigurationManager.GetSection("foo");
foreach (var s in section.MyStrings)
    Console.WriteLine(s); //for example

To check for duplicates you need to compare distinct pairs.

In this case, myvar should be a boolean value. If this variable is true, it will show the div, if it's false.. It will hide.

Check this out.

Share the password (a char[]) and salt (a byte[]—8 bytes selected by a SecureRandom makes a good salt—which doesn't need to be kept secret) with the recipient out-of-band. Then to derive a good key from this information:

/* Derive the key, given password and salt. */
SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");
KeySpec spec = new PBEKeySpec(password, salt, 65536, 256);
SecretKey tmp = factory.generateSecret(spec);
SecretKey secret = new SecretKeySpec(tmp.getEncoded(), "AES");

The magic numbers (which could be defined as constants somewhere) 65536 and 256 are the key derivation iteration count and the key size, respectively.

The key derivation function is iterated to require significant computational effort, and that prevents attackers from quickly trying many different passwords. The iteration count can be changed depending on the computing resources available.

The key size can be reduced to 128 bits, which is still considered "strong" encryption, but it doesn't give much of a safety margin if attacks are discovered that weaken AES.

Used with a proper block-chaining mode, the same derived key can be used to encrypt many messages. In Cipher Block Chaining (CBC), a random initialization vector (IV) is generated for each message, yielding different cipher text even if the plain text is identical. CBC may not be the most secure mode available to you (see AEAD below); there are many other modes with different security properties, but they all use a similar random input. In any case, the outputs of each encryption operation are the cipher text and the initialization vector:

/* Encrypt the message. */
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, secret);
AlgorithmParameters params = cipher.getParameters();
byte[] iv = params.getParameterSpec(IvParameterSpec.class).getIV();
byte[] ciphertext = cipher.doFinal("Hello, World!".getBytes(StandardCharsets.UTF_8));

Store the ciphertext and the iv. On decryption, the SecretKey is regenerated in exactly the same way, using using the password with the same salt and iteration parameters. Initialize the cipher with this key and the initialization vector stored with the message:

/* Decrypt the message, given derived key and initialization vector. */
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.DECRYPT_MODE, secret, new IvParameterSpec(iv));
String plaintext = new String(cipher.doFinal(ciphertext), StandardCharsets.UTF_8);
System.out.println(plaintext);

Java 7 included API support for AEAD cipher modes, and the "SunJCE" provider included with OpenJDK and Oracle distributions implements these beginning with Java 8. One of these modes is strongly recommended in place of CBC; it will protect the integrity of the data as well as their privacy.

A java.security.InvalidKeyException with the message "Illegal key size or default parameters" means that the cryptography strength is limited; the unlimited strength jurisdiction policy files are not in the correct location. In a JDK, they should be placed under ${jdk}/jre/lib/security

Based on the problem description, it sounds like the policy files are not correctly installed. Systems can easily have multiple Java runtimes; double-check to make sure that the correct location is being used.

In conclusion, when you use a local variable of a type that implements IDisposable, always, without exception, use using¹.

If you use nonlocal IDisposable variables, then always implement the IDisposable pattern.

Two simple rules, no exception¹. Preventing resource leaks otherwise is a real pain in the *ss.

¹⁾: The only exception is – when you're handling exceptions. It might then be less code to call Dispose explicitly in the finally block.

In kotlin :

private fun File.writeBitmap(bitmap: Bitmap, format: Bitmap.CompressFormat, quality: Int) {
    outputStream().use { out ->
        bitmap.compress(format, quality, out)
        out.flush()
    }
}

usage example:

File(exportDir, "map.png").writeBitmap(bitmap, Bitmap.CompressFormat.PNG, 85)

I had the same issue.. and you don't need to add a physical column.. cuz now you will have to maintain it.. what you can do is add a generic column in the select query:

EX:

select tb1.col1, tb1.col2, tb1.col3 ,
( 
select 'Match' from table2 as tbl2
where tbl1.col1 = tbl2.col1 and tab1.col2 = tbl2.col2
)  
from myTable as tbl1

No multi-line comments in R as of version 2.12 and unlikely to change. In most environments, you can comment blocks by highlighting and toggle-comment. In emacs, this is 'M-x ;'.

As answered by Ian L, I also use NPM to manage my scripts.

Example:

{_x000D_
  "scripts": {_x000D_
    "ios": "react-native run-ios --simulator=\"iPad Air 2\"",_x000D_
    "devices": "xcrun simctl list devices"_x000D_
  }_x000D_
}

This way, I can quickly get what I need:

1. List all devices: npm run devices
2. Run the default simulator: npm run ios

Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).

javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456

Then load the properties to your environment from your code. This makes your application configurable.

FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);

Very simple solution to the problem when your NetBeans or Eclipse IDE seems to be using too much memory:

1. Disable the plugins you are not using.
2. close the projects you are not working on.

I was facing similar problem with Netbeans 7.0 on my Linux Mint as well Ubuntu box. Netbeans was using > 700 MiB space and 50-80% CPU. Then I decided do some clean up. I had 30 plugins installed, and I was not using most of them. So, I disabled the plugins I was not using, a whopping 19 plug ins I disabled. now memory uses down to 400+ MiB and CPU uses down to 10 and at max to 50%.

Now my life is much easier.

Given a group of radio buttons:

<input type="radio" id="radio1" name="radioGroup" value="1">
<input type="radio" id="radio2" name="radioGroup" value="2">

You can test whether a specific one is checked using jQuery as follows:

if ($("#radio1").prop("checked")) {
   // do something
}

// OR
if ($("#radio1").is(":checked")) {
   // do something
}

// OR if you don't have ids set you can go by group name and value
// (basically you need a selector that lets you specify the particular input)
if ($("input[name='radioGroup'][value='1']").prop("checked"))

You can get the value of the currently checked one in the group as follows:

$("input[name='radioGroup']:checked").val()

You can pass it like this

let param: any = {'userId': 2};
this.http.get(`${ApiUrl}`, {params: param})

The following should work:

svnlook youngest <repo-path>

It returns a single revision number.

You can try something like this:

    <script type="text/javascript">
        function simulateLogin(userName)
        {
            var userNameField = document.getElementById("username");
            userNameField.value = userName;
            var goButton = document.getElementById("go");
            goButton.click();
        }

        simulateLogin("testUser");
</script>

Briefly;

1) You must typed following command for RepoDigests of a docker repo;

## docker inspect <registry-host>:<registry-port>/<image-name>:<tag>
> docker inspect 174.24.100.50:8448/example-image:latest


[
    {
        "Id": "sha256:16c5af74ed970b1671fe095e063e255e0160900a0e12e1f8a93d75afe2fb860c",
        "RepoTags": [
            "174.24.100.50:8448/example-image:latest",
            "example-image:latest"
        ],
        "RepoDigests": [
            "174.24.100.50:8448/example-image@sha256:5580b2110c65a1f2567eeacae18a3aec0a31d88d2504aa257a2fecf4f47695e6"
        ],
...
...

${digest} = sha256:5580b2110c65a1f2567eeacae18a3aec0a31d88d2504aa257a2fecf4f47695e6

2) Use registry REST API

  ##curl -u username:password -vk -X DELETE registry-host>:<registry-port>/v2/<image-name>/manifests/${digest}


  >curl -u example-user:example-password -vk -X DELETE http://174.24.100.50:8448/v2/example-image/manifests/sha256:5580b2110c65a1f2567eeacae18a3aec0a31d88d2504aa257a2fecf4f47695e6

You should get a 202 Accepted for a successful invocation.

3-) Run Garbage Collector

docker exec registry bin/registry garbage-collect --dry-run /etc/docker/registry/config.yml

registry — registry container name.

I tried to add the primary key afterwards by changing the sqlite_master table directly. This trick seems to work. It is a hack solution of course.

In short: create a regular (unique) index on the table, then make the schema writable and change the name of the index to the form reserved by sqlite to identify a primary key index, (i.e. sqlite_autoindex_XXX_1, where XXX is the table name) and set the sql string to NULL. At last change the table definition itself. One pittfal: sqlite does not see the index name change until the database is reopened. This seems like a bug, but not a severe one (even without reopening the database, you can still use it).

Suppose the table looks like:

CREATE TABLE tab1(i INTEGER, j INTEGER, t TEXT);

Then I did the following:

BEGIN;
CREATE INDEX pk_tab1 ON tab1(i,j);
pragma writable_schema=1;
UPDATE sqlite_master SET name='sqlite_autoindex_tab1_1',sql=null WHERE name='pk_tab1';
UPDATE sqlite_master SET sql='CREATE TABLE tab1(i integer,j integer,t text,primary key(i,j))' WHERE name='tab1';
COMMIT;

Some tests (in sqlite shell):

sqlite> explain query plan select * from tab1 order by i,j;
0|0|0|SCAN TABLE tab1 USING INDEX sqlite_autoindex_tab1_1
sqlite> drop index sqlite_autoindex_tab1_1;
Error: index associated with UNIQUE or PRIMARY KEY constraint cannot be dropped    

git add .
git reset

git add . will stage ALL the files telling git that you have resolved the conflict

git reset will unstage ALL the staged files without creating a commit

Change the = to : to fix the error.

var makeRequest = function(message) {<br>
 var options = {<br>
  host: 'localhost',<br>
  port : 8080,<br>
  path : '/',<br>
  method: 'POST'<br>
 }

For shared libraries libNAME.so the -D switch was necessary to see symbols in my Linux

nm -D libNAME.so

and for static library as reported by others

nm -g libNAME.a

Try this "one-liner" from Delta's Blog, String To MemoryStream (C#).

MemoryStream stringInMemoryStream =
   new MemoryStream(ASCIIEncoding.Default.GetBytes("Your string here"));

The string will be loaded into the MemoryStream, and you can read from it. See Encoding.GetBytes(...), which has also been implemented for a few other encodings.

You should iterate over the keys and get the values using square brackets.
