Here is an example how to set a request header in a jQuery Ajax call:

$.ajax({
  type: "POST",
  beforeSend: function(request) {
    request.setRequestHeader("Authority", authorizationToken);
  },
  url: "entities",
  data: "json=" + escape(JSON.stringify(createRequestObject)),
  processData: false,
  success: function(msg) {
    $("#results").append("The result =" + StringifyPretty(msg));
  }
});

Here are my two cents on how to do the transformations for secondary axis. First, you want to couple the the ranges of the primary and secondary data. This is usually messy in terms of polluting your global environment with variables you don't want.

To make this easier, we'll make a function factory that produces two functions, wherein scales::rescale() does all the heavy lifting. Because these are closures, they are aware of the environment in which they were created, so they 'have a memory' of the to and from parameters generated before creation.

• One functions does the forward transformation: transforms the secondary data to the primary scale.
• The second function does the reverse transformation: transforms data in primary units to secondary units.

library(ggplot2)
library(scales)

# Function factory for secondary axis transforms
train_sec <- function(primary, secondary) {
  from <- range(secondary)
  to   <- range(primary)
  # Forward transform for the data
  forward <- function(x) {
    rescale(x, from = from, to = to)
  }
  # Reverse transform for the secondary axis
  reverse <- function(x) {
    rescale(x, from = to, to = from)
  }
  list(fwd = forward, rev = reverse)
}

This seems all rather complicated, but making the function factory makes all the rest easier. Now, before we make a plot, we'll produce the relevant functions by showing the factory the primary and secondary data. We'll use the economics dataset which has very different ranges for the unemploy and psavert columns.

sec <- with(economics, train_sec(unemploy, psavert))

Then we use y = sec$fwd(psavert) to rescale the secondary data to primary axis, and specify ~ sec$rev(.) as the transformation argument to the secondary axis. This gives us a plot where the primary and secondary ranges occupy the same space on the plot.

ggplot(economics, aes(date)) +
  geom_line(aes(y = unemploy), colour = "blue") +
  geom_line(aes(y = sec$fwd(psavert)), colour = "red") +
  scale_y_continuous(sec.axis = sec_axis(~sec$rev(.), name = "psavert"))

The factory is slightly more flexible than that, because if you simply want to rescale the maximum, you can pass in data that has the lower limit at 0.

# Rescaling the maximum
sec <- with(economics, train_sec(c(0, max(unemploy)),
                                 c(0, max(psavert))))

ggplot(economics, aes(date)) +
  geom_line(aes(y = unemploy), colour = "blue") +
  geom_line(aes(y = sec$fwd(psavert)), colour = "red") +
  scale_y_continuous(sec.axis = sec_axis(~sec$rev(.), name = "psavert"))

^{Created on 2021-02-05 by the reprex package (v0.3.0)}

I admit the difference in this example is not that very obvious, but if you look closely you can see that the maxima are the same and the red line goes lower than the blue one.

You can use static methods from Character class to get Numeric value from char.

char x = '9';

if (Character.isDigit(x)) { // Determines if the specified character is a digit.
    int y = Character.getNumericValue(x); //Returns the int value that the 
                                          //specified Unicode character represents.
    System.out.println(y);
}

If you have a newer distro with a newer systemd (systemd version 236 or newer), you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME.

Long story:

In newer versions of systemd there is a relatively new option (the github request is from 2016 ish and the enhancement is merged/closed 2017 ish) where you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME. The file:path option is documented in the most recent systemd.exec man page.

This new feature is relatively new and so is not available for older distros like centos-7 (or any centos before that).

$mysearch="Your Search Name";
$query = mysql_query("SELECT * FROM table");
$c=0;
// set array
$array = array();

// look through query
while($row = mysql_fetch_assoc($query)){

  // add each row returned into an array
  $array[] = $row;
  $c++;
}

for($i=0;$i=$c;$i++)
{
if($array[i]['username']==$mysearch)
{
// name found
}
}

If and only if i had to use some js library, i would do that with SMTPJs library.It offers encryption to your credentials such as username, password etc.

Use FLOOR(), if you want to round your decimal to the lower integer. Examples:

FLOOR(1.9) => 1
FLOOR(1.1) => 1

Use ROUND(), if you want to round your decimal to the nearest integer. Examples:

ROUND(1.9) => 2
ROUND(1.1) => 1

Use CEIL(), if you want to round your decimal to the upper integer. Examples:

CEIL(1.9) => 2
CEIL(1.1) => 2

Here is the code with tests cases ;) :

@Test
public void testNullStringShouldReturnStringWithSpaces() throws Exception {
    String fixedString = writeAtFixedLength(null, 5);
    assertEquals(fixedString, "     ");
}

@Test
public void testEmptyStringReturnStringWithSpaces() throws Exception {
    String fixedString = writeAtFixedLength("", 5);
    assertEquals(fixedString, "     ");
}

@Test
public void testShortString_ReturnSameStringPlusSpaces() throws Exception {
    String fixedString = writeAtFixedLength("aa", 5);
    assertEquals(fixedString, "aa   ");
}

@Test
public void testLongStringShouldBeCut() throws Exception {
    String fixedString = writeAtFixedLength("aaaaaaaaaa", 5);
    assertEquals(fixedString, "aaaaa");
}


private String writeAtFixedLength(String pString, int lenght) {
    if (pString != null && !pString.isEmpty()){
        return getStringAtFixedLength(pString, lenght);
    }else{
        return completeWithWhiteSpaces("", lenght);
    }
}

private String getStringAtFixedLength(String pString, int lenght) {
    if(lenght < pString.length()){
        return pString.substring(0, lenght);
    }else{
        return completeWithWhiteSpaces(pString, lenght - pString.length());
    }
}

private String completeWithWhiteSpaces(String pString, int lenght) {
    for (int i=0; i<lenght; i++)
        pString += " ";
    return pString;
}

I like TDD ;)

From wiki.answers.com:

The term declaration means (in C) that you are telling the compiler about type, size and in case of function declaration, type and size of its parameters of any variable, or user defined type or function in your program. No space is reserved in memory for any variable in case of declaration. However compiler knows how much space to reserve in case a variable of this type is created.

for example, following are all declarations:

extern int a; 
struct _tagExample { int a; int b; }; 
int myFunc (int a, int b);

Definition on the other hand means that in additions to all the things that declaration does, space is also reserved in memory. You can say "DEFINITION = DECLARATION + SPACE RESERVATION" following are examples of definition:

int a; 
int b = 0; 
int myFunc (int a, int b) { return a + b; } 
struct _tagExample example; 

see Answers.

Parameterize the query and pass the ids in using a Table Valued Parameter.

For example, define the following type:

CREATE TYPE IdTable AS TABLE (Id INT NOT NULL PRIMARY KEY)

Along with the following stored procedure:

CREATE PROCEDURE sp__Procedure_Name
    @OrderIDs IdTable READONLY,
AS

    SELECT *
    FROM table
    WHERE Col IN (SELECT Id FROM @OrderIDs)

You can easily follow the following code

import pandas as pd 
import numpy as np 
        
classxii = {'Name':['Karan','Ishan','Aditya','Anant','Ronit'],
            'Subject':['Accounts','Economics','Accounts','Economics','Accounts'],
            'Score':[87,64,58,74,87],
            'Grade':['A1','B2','C1','B1','A2']}

df = pd.DataFrame(classxii,index = ['a','b','c','d','e'],columns=['Name','Subject','Score','Grade'])
print(df)

#use the below for mean if you already have a dataframe
print('mean of score is:')
print(df[['Score']].mean())

As mentioned, you simply want the standard R apply function applied to columns (MARGIN=2):

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A)

Or, for short:

wifi[,4:9] <- apply(wifi[,4:9], 2, A)

This updates columns 4:9 in-place using the A() function. Now, let's assume that na.rm is an argument to A(), which it probably should be. We can pass na.rm=T to remove NA values from the computation like so:

wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A, na.rm=T)

The same is true for any other arguments you want to pass to your custom function.

For disabling all the database related autoconfiguration and exit from:

Cannot determine embedded database driver class for database type NONE

1. Using annotation:

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(PayPalApplication.class, args);
    }
}

2. Using Application.properties:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration, org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

Use the ToDictionary method directly.

var result = 
  // as Jon Skeet pointed out, OrderBy is useless here, I just leave it 
  // show how to use OrderBy in a LINQ query
  myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
                   .ToDictionary(mc => mc.KeyProp.ToString(), 
                                 mc => mc.ValueProp.ToString(), 
                                 StringComparer.OrdinalIgnoreCase);

This works for me in my onClickListener:

yourView.postDelayed(new Runnable() {               
    @Override
    public void run() {         
        yourView.invalidate();
        System.out.println("Height yourView: " + yourView.getHeight());
        System.out.println("Width yourView: " + yourView.getWidth());               
    }
}, 1);

PHP has a built in function called bool chmod(string $filename, int $mode )

http://php.net/function.chmod

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);
    chmod($file, 0777);  //changed to add the zero
    return true;
}

Another good example might be: you have a class that supports the use of cartesian (x, y, z), spherical (r, theta, phi) and cylindrical coordinates (r, phi, z). For purposes of establishing equality (equals method), you would probably want to convert all representations to one "canonical" representation of your choosing, e.g. spherical coordinates. (Or maybe you would want to do this in general - i.e. use one internal representation.) I am not an expert, but this did occur to me as maybe a good concrete example.

You can use wsdlrdr also. EasySoap is basically rewrite of wsdlrdr with some extra methods. Be careful that easysoap doesn't have the getNamespace method which is available at wsdlrdr.

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5); 

Wikipedia never lets down:

As of [email protected]+ you can simply do:

npm update <package name>

This will automatically update the package.json file. We don't have to update the latest version manually and then use npm update <package name>

You can still get the old behavior using

npm update --no-save

This is the hacky way that I am getting around this, at least it works in all current browsers (on Windows, I don't own a Mac):

if (navigator.geolocation) {
    var location_timeout = setTimeout("geolocFail()", 10000);

    navigator.geolocation.getCurrentPosition(function(position) {
        clearTimeout(location_timeout);

        var lat = position.coords.latitude;
        var lng = position.coords.longitude;

        geocodeLatLng(lat, lng);
    }, function(error) {
        clearTimeout(location_timeout);
        geolocFail();
    });
} else {
    // Fallback for no geolocation
    geolocFail();
}

This will also work if someone clicks the close or chooses no or chooses the Never Share option on Firefox.

Clunky, but it works.

You can use Collections.sort and pass your own Comparator<ActiveAlarm>

You can shorten this:

if 'key1' in dict:
    ...

However, this is at best a cosmetic improvement. Why do you believe this is not the best way?

$array = 1..5 | foreach { $false }

std::queue<myclass*> my_queue; will do the job.

See here for more information on this container.

As shown here, the second argument to substr is the length, not the ending position:

string substr ( size_t pos = 0, size_t n = npos ) const;

Generate substring

Returns a string object with its contents initialized to a substring of the current object. This substring is the character sequence that starts at character position pos and has a length of n characters.

Your line b = a.substr(i,i+1); will generate, for values of i:

substr(0,1) = 1
substr(1,2) = 23
substr(2,3) = 345
substr(3,4) = 45  (since your string stops there).

What you need is b = a.substr(i,2);

You should also be aware that your output will look funny for a number like 12045. You'll get 12 20 4 45 due to the fact that you're using atoi() on the string section and outputting that integer. You might want to try just outputing the string itself which will be two characters long:

b = a.substr(i,2);
cout << b << " ";

In fact, the entire thing could be more simply written as:

#include <iostream>
#include <string>
using namespace std;
int main(void) {
    string a;
    cin >> a;
    for (int i = 0; i < a.size() - 1; i++)
        cout << a.substr(i,2) << " ";
    cout << endl;
    return 0;
}

Use a container with Boxdercoration.

 BoxDecoration(
    border: Border.all(
      width: 3.0
    ),
    borderRadius: BorderRadius.circular(10.0)
  );

You can pass any number of arguments to the function that apply is calling through either unnamed arguments, passed as a tuple to the args parameter, or through other keyword arguments internally captured as a dictionary by the kwds parameter.

For instance, let's build a function that returns True for values between 3 and 6, and False otherwise.

s = pd.Series(np.random.randint(0,10, 10))
s

0    5
1    3
2    1
3    1
4    6
5    0
6    3
7    4
8    9
9    6
dtype: int64

s.apply(lambda x: x >= 3 and x <= 6)

0     True
1     True
2    False
3    False
4     True
5    False
6     True
7     True
8    False
9     True
dtype: bool

This anonymous function isn't very flexible. Let's create a normal function with two arguments to control the min and max values we want in our Series.

def between(x, low, high):
    return x >= low and x =< high

We can replicate the output of the first function by passing unnamed arguments to args:

s.apply(between, args=(3,6))

Or we can use the named arguments

s.apply(between, low=3, high=6)

Or even a combination of both

s.apply(between, args=(3,), high=6)

I got the question "say you were writing the built in function for casting an integer to a string in PHP, how would you write that function" in a programming interview. Here's a solution.

$nums = ["0","1","2","3","4","5","6","7","8","9"];
$int = 15939; 
$string = ""; 
while ($int) { 
    $string .= $nums[$int % 10]; 
    $int = (int)($int / 10); 
} 
$result = strrev($string);

You can use static constructor to initialization static variable. Static constructor will be entry point for your class

public class MyClass
{

    static MyClass()
    {

        //write your initialization code here
    }

}

To change status bar color use setStatusBarColor(int color). According the javadoc, we also need set some flags on the window.

Working snippet of code:

Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.setStatusBarColor(ContextCompat.getColor(activity, R.color.example_color));

Keep in mind according Material Design guidelines status bar color and action bar color should be different:

• ActionBar should use primary 500 color
• StatusBar should use primary 700 color

Look at the screenshot below:

DBQuery.shellBatchSize = 300

will do.

I propose a solution without modules (accumulate modules is never recommended for maintainability especially for small functions that can be written in a few lines...) :

LAST UPDATE :

In v10.12.0, NodeJS impletement recursive options :

// Create recursive folder
fs.mkdir('my/new/folder/create', { recursive: true }, (err) => { if (err) throw err; });

UPDATE :

// Get modules node
const fs   = require('fs');
const path = require('path');

// Create 
function mkdirpath(dirPath)
{
    if(!fs.accessSync(dirPath, fs.constants.R_OK | fs.constants.W_OK))
    {
        try
        {
            fs.mkdirSync(dirPath);
        }
        catch(e)
        {
            mkdirpath(path.dirname(dirPath));
            mkdirpath(dirPath);
        }
    }
}

// Create folder path
mkdirpath('my/new/folder/create');

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

All objects in JavaScript are implemented as hashtables/associative arrays. So, the following are the equivalent:

alert(myObj["SomeProperty"]);
alert(myObj.SomeProperty);

And, as already indicated, you "remove" a property from an object via the delete keyword, which you can use in two ways:

delete myObj["SomeProperty"];
delete myObj.SomeProperty;

Hope the extra info helps...

The answer to this question simply put is: Don't use BOOLEAN with Oracle-- PL/SQL is dumb and it doesn't work. Use another data type to run your process.

A note to SSRS report developers with Oracle datasource: You can use BOOLEAN parameters, but be careful how you implement. Oracle PL/SQL does not play nicely with BOOLEAN, but you can use the BOOLEAN value in the Tablix Filter if the data resides in your dataset. This really tripped me up, because I have used BOOLEAN parameter with Oracle data source. But in that instance I was filtering against Tablix data, not SQL query.

If the data is NOT in your SSRS Dataset Fields, you can rewrite the SQL something like this using an INTEGER parameter:

__

<ReportParameter Name="paramPickupOrders">
  <DataType>Integer</DataType>
  <DefaultValue>
    <Values>
      <Value>0</Value>
    </Values>
  </DefaultValue>
  <Prompt>Pickup orders?</Prompt>
  <ValidValues>
    <ParameterValues>
      <ParameterValue>
        <Value>0</Value>
        <Label>NO</Label>
      </ParameterValue>
      <ParameterValue>
        <Value>1</Value>
        <Label>YES</Label>
      </ParameterValue>
    </ParameterValues>
  </ValidValues>
</ReportParameter>

...

<Query>
<DataSourceName>Gmenu</DataSourceName>
<QueryParameters>
  <QueryParameter Name=":paramPickupOrders">
    <Value>=Parameters!paramPickupOrders.Value</Value>
  </QueryParameter>
<CommandText>
    where 
        (:paramPickupOrders = 0 AND ordh.PICKUP_FLAG = 'N'
        OR :paramPickupOrders = 1 AND ordh.PICKUP_FLAG = 'Y' )

If the data is in your SSRS Dataset Fields, you can use a tablix filter with a BOOLEAN parameter:

__

</ReportParameter>
<ReportParameter Name="paramFilterOrdersWithNoLoad">
  <DataType>Boolean</DataType>
  <DefaultValue>
    <Values>
      <Value>false</Value>
    </Values>
  </DefaultValue>
  <Prompt>Only orders with no load?</Prompt>
</ReportParameter>

...

<Tablix Name="tablix_dsMyData">
<Filters>
  <Filter>
    <FilterExpression>
        =(Parameters!paramFilterOrdersWithNoLoad.Value=false) 
        or (Parameters!paramFilterOrdersWithNoLoad.Value=true and Fields!LOADNUMBER.Value=0)
    </FilterExpression>
    <Operator>Equal</Operator>
    <FilterValues>
      <FilterValue DataType="Boolean">=true</FilterValue>
    </FilterValues>
  </Filter>
</Filters>

You can take keys or values per index:

int value = _dict.Values.ElementAt(5);//ElementAt value should be <= _dict.Count - 1
string key = _dict.Keys.ElementAt(5);//ElementAt value should be  < =_dict.Count - 1

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] == 3:
    from urllib.request import urlopen
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlopen


# Your code where you can use urlopen
with urlopen("http://www.python.org") as url:
    s = url.read()

print(s)

public static String currencyFormat(BigDecimal n) {
    return NumberFormat.getCurrencyInstance().format(n);
}

It will use your JVM’s current default Locale to choose your currency symbol. Or you can specify a Locale.

NumberFormat.getInstance(Locale.US)

For more info, see NumberFormat class.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

The windows equivalent to a cron job is a scheduled task.

A scheduled task can be created as described by Alex and Rudu, but it can also be done command line with schtasks (if you for instance need to script it or add it to version control).

An example:

schtasks /create /tn calculate /tr calc /sc weekly /d MON /st 06:05 /ru "System"

Creates the task calculate, which starts the calculator(calc) every monday at 6:05 (should you ever need that.)

All available commands can be found here: http://technet.microsoft.com/en-us/library/cc772785%28WS.10%29.aspx

It works on windows server 2008 as well as windows server 2003.

An easy way of doing this:

SELECT  ('[' || to_json('Some "text"'::TEXT) || ']')::json ->> 0;

Just convert the json string into a json list

1) setState actions are asynchronous and are batched for performance gains. This is explained in the documentation of setState.

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value. There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.

2) Why would they make setState async as JS is a single threaded language and this setState is not a WebAPI or server call?

This is because setState alters the state and causes rerendering. This can be an expensive operation and making it synchronous might leave the browser unresponsive.

Thus the setState calls are asynchronous as well as batched for better UI experience and performance.

Both are valid but I normally choose interfaces. A class (abstract or not) is not needed if there is no implementations.

As an advise, try to choose the location of your constants wisely, they are part of your external contract. Do not put every single constant in one file.

For example, if a group of constants is only used in one class or one method put them in that class, the extended class or the implemented interfaces. If you do not take care you could end up with a big dependency mess.

Sometimes an enumeration is a good alternative to constants (Java 5), take look at: http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html

Alternate way using Zk-Client:

If you do not prefer to pass arguments to ./zookeeper-shell.sh and want to see the broker details from Zookeeper CLI, you need to install standalone Zookeeper (As traditional Kafka do not comes up with Jline JAR).

Once you install(unzip) the standalone Zookeeper,then:

• Run the Zookeeper CLI:
  $ zookeeper/bin/zkCli.sh -server localhost:2181 #Make sure your Broker is already running

• If it is successful, you can see the Zk client running as:

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]

• From here you can explore the broker details using various commands:

$ ls /brokers/ids # Gives the list of active brokers
$ ls /brokers/topics #Gives the list of topics
$ get /brokers/ids/0 #Gives more detailed information of the broker id '0'

This is an old question, but I found that when you create a string like this:

<string name="newline_test">My
New line test</string>

The output in your app will be like this (no newline)

My New line test

When you put the string in quotation marks

<string name="newline_test">"My
New line test"</string>

the newline will appear:

My 
New line test

The problem is the way you are using it in code. Just try the below code

public partial class MainView : Window
{
    public MainView()
    {
        InitializeComponent();

        ImageBrush myBrush = new ImageBrush();
        myBrush.ImageSource =
            new BitmapImage(new Uri("pack://application:,,,/icon.jpg", UriKind.Absolute));
        this.Background = myBrush;
    }
}

I don't see it mentioned here, but splatting your arguments is a useful alternative and becomes especially useful if you are building out the arguments to a command dynamically (as opposed to using Invoke-Expression). You can splat with arrays for positional arguments and hashtables for named arguments. Here are some examples:

Splat With Arrays (Positional Arguments)

Test-Connection with Positional Arguments

Test-Connection www.google.com localhost

With Array Splatting

$argumentArray = 'www.google.com', 'localhost'
Test-Connection @argumentArray

Note that when splatting, we reference the splatted variable with an @ instead of a $. It is the same when using a Hashtable to splat as well.

Splat With Hashtable (Named Arguments)

Test-Connection with Named Arguments

Test-Connection -ComputerName www.google.com -Source localhost

With Hashtable Splatting

$argumentHash = @{
  ComputerName = 'www.google.com'
  Source = 'localhost'
}
Test-Connection @argumentHash

Splat Positional and Named Arguments Simultaneously

Test-Connection With Both Positional and Named Arguments

Test-Connection www.google.com localhost -Count 1

Splatting Array and Hashtables Together

$argumentHash = @{
  Count = 1
}
$argumentArray = 'www.google.com', 'localhost'
Test-Connection @argumentHash @argumentArray

After looking at the SVG Recommendation I've come to the understanding that the baseline properties are meant to position text relative to other text, especially when mixing different fonts and or languages. If you want to postion text so that it's top is at y then you need use dy = "y + the height of your text".

Drawable image = ImageOperations(context,ed.toString(),"image.jpg");
            ImageView imgView = new ImageView(context);
            imgView = (ImageView)findViewById(R.id.image1);
            imgView.setImageDrawable(image);

or

setImageDrawable(getResources().getDrawable(R.drawable.icon));

I don't know that you can do it in Chrome outside of Windows -- some Googling shows that Chrome (and therefore possibly Chromium) might respond well to a certain registry hack.

However, if you're just looking for a simple solution without modifying your code base, have you considered Firefox? In the about:config you can search for "network.http.max" and there are a few values in there that are definitely worth looking at.

Also, for a device that will not be moving (i.e. it is mounted in a fixed location) you should consider not using Wi-Fi (even a Home-Plug would be a step up as far as latency / stability / dropped connections go).

You can use the following as extension method

 public static void RemoveByValue<T,T1>(this Dictionary<T,T1> src , T1 Value)
    {
        foreach (var item in src.Where(kvp => kvp.Value.Equals( Value)).ToList())
        {
            src.Remove(item.Key);
        }
    }

By default node package is nodejs, so use

$ nodejs -v

or

$ nodejs --version 

You can make a link using

$ sudo ln -s /usr/bin/nodejs /usr/bin/node

then u can use

$ node --version

or

$ node -v

This is a simple circle as a drawable in Android.

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

   <solid 
       android:color="#666666"/>

   <size 
       android:width="120dp"
        android:height="120dp"/>
</shape>

private void showImage(ImageView img, String absolutePath) {
  
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 8;
    Bitmap bitmapPicture = BitmapFactory.decodeFile(absolutePath);
    img.setImageBitmap(bitmapPicture);

}

Since functions in Javascript can be called with any number of arguments, and the document doesn't place any restriction on the onFulfilled() method's arguments besides the below clause, I think that you can pass multiple arguments to the onFulfilled() method as long as the promise's value is the first argument.

2.2.2.1 it must be called after promise is fulfilled, with promise’s value as its first argument.

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

Right...with strings...the moment you deviate from primitives or strings things change and you need to implement hashcode/equals to get the desired effect.

EDIT: Initialize your ArrayList<String> then attempt to add an item.

You have to create a new template for item selection like this.

<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="ListBoxItem">
            <Border
                BorderThickness="{TemplateBinding Border.BorderThickness}"
                Padding="{TemplateBinding Control.Padding}"
                BorderBrush="{TemplateBinding Border.BorderBrush}"
                Background="{TemplateBinding Panel.Background}"
                SnapsToDevicePixels="True">
                <ContentPresenter
                    Content="{TemplateBinding ContentControl.Content}"
                    ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}"
                    HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
                    VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
                    SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" />
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>

I am not sure will this be useful for anyone, since I had to provide other users of the system to schedule the jobs, without giving them access to the actual server(windows) Task Scheduler, I created this reusable app.

Please note users have access to one shared folder on server where they can create required command/task/.bat file. This task then can be scheduled using this app.

App name is Django_Windows_Scheduler

ScreenShot:

Datatables have a .Select method, which returns a rows array according to the criteria you specify. Something like this:

Dim oRows() As DataRow

oRows = dtCountries.Select("CountryName = '" & userinput & "'")

If oRows.Count = 0 Then
   ' No rows found
Else
   ' At least one row found. Could be more than one
End If

Of course, if userinput contains ' character, it would raise an exception (like if you query the database). You should escape the ' characters (I use a function to do that).

Try http://www.jsonschema2pojo.org

Or the jsonschema2pojo plug-in for Maven:

        <plugin>
            <groupId>org.jsonschema2pojo</groupId>
            <artifactId>jsonschema2pojo-maven-plugin</artifactId>
            <version>1.0.2</version>
            <configuration>
                <sourceDirectory>${basedir}/src/main/resources/schemas</sourceDirectory>
                <targetPackage>com.myproject.jsonschemas</targetPackage>
                <sourceType>json</sourceType>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

The <sourceType>json</sourceType> covers the case where the sources are json (like the OP). If you have actual json schemas, remove this line.

Updated in 2014: Two things have happened since Dec '09 when this question was asked:

• The JSON Schema spec has moved on a lot. It's still in draft (not finalised) but it's close to completion and is now a viable tool specifying your structural rules

• I've recently started a new open source project specifically intended to solve your problem: jsonschema2pojo. The jsonschema2pojo tool takes a json schema document and generates DTO-style Java classes (in the form of .java source files). The project is not yet mature but already provides coverage of the most useful parts of json schema. I'm looking for more feedback from users to help drive the development. Right now you can use the tool from the command line or as a Maven plugin.

Hope this helps!

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

Something like:

find /path/ -type f -exec stat \{} --printf="%y\n" \; | 
     sort -n -r | 
     head -n 1

Explanation:

• the find command will print modification time for every file recursively ignoring directories (according to the comment by IQAndreas you can't rely on the folders timestamps)
• sort -n (numerically) -r (reverse)
• head -n 1: get the first entry

I had the same problem. I removed virtual device and run app on my phone - worked well. To remove virtual device: Click icon "AVD Manager" in Android Studio, select virtual device and in context menu click "Delete". Then turn on on the phone "Developer mode". Connect phone via USB to the laptop.

It depends on your purpose. If you program for the Web, avoid indexOf, it isn't supported by Internet Explorer 6 (lot of them still used!), or do conditional use:

if (yourArray.indexOf !== undefined) result = yourArray.indexOf(target);
else result = customSlowerSearch(yourArray, target);

indexOf is probably coded in native code, so it is faster than anything you can do in JavaScript (except binary search/dichotomy if the array is appropriate). Note: it is a question of taste, but I would do a return false; at the end of your routine, to return a true Boolean...

Find element with id in row using jquery

$(document).ready(function () {
$("button").click(function() {
    //find content of different elements inside a row.
    var nameTxt = $(this).closest('tr').find('.name').text();
    var emailTxt = $(this).closest('tr').find('.email').text();
    //assign above variables text1,text2 values to other elements.
    $("#name").val( nameTxt );
    $("#email").val( emailTxt );
    });
});

Since the question is about what is the fastest method, I thought I'd throw up add some perf metrics.

TL;DR The winner, by a wide margin, is the + operator, and please never use regex

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

The best solution would be to go to http://projects.eclipse.org/projects/tools.pdt/downloads where you will find the URL to the most updated PDT, as most of the URLS listed above are hitting a 404. Then pasting the URL to eclipse.

Since my images were created using ajax, and therefore not available on windows.load.

$("#page").delegate('img', 'dragstart', function (event) { event.preventDefault(); });

This way I can control which section blocks the behavior, it only uses one event binding and it works for future ajax created images without having to do anything.

With jQuery new on binding:

$('#page').on('dragstart', 'img', function(event) { event.preventDefault(); }); (thanks @ialphan)

You shouldn't use:

Page.Response.Redirect(Page.Request.Url.ToString(), true);

because this might cause a runtime error.

A better approach is:

Page.Response.Redirect(Page.Request.Url.ToString(), false);
        Context.ApplicationInstance.CompleteRequest();

add:

import math

at beginning. and then use:

math.sqrt(num)  # or any other function you deem neccessary

You should use profiles.

<profiles>
    <profile>
        <id>otherOutputDir</id>
        <build>
            <directory>yourDirectory</directory>
        </build>
    </profile>
</profiles>

And start maven with your profile

mvn compile -PotherOutputDir

If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :

<properties>
    <buildDirectory>${project.basedir}/target</buildDirectory>
</properties>

<build>
    <directory>${buildDirectory}</directory>
</build>

And compile like this :

mvn compile -DbuildDirectory=test

That's because you can't change the target directory by using -Dproject.build.directory

var top = $('html').offset().top;

should do it.

edit: this is the negative of $(document).scrollTop()

You can do this with animation-keyframe rather than transition. Change your hover declaration and add the animation keyframe, you might also need to add browser prefixes for -moz- and -webkit-. See https://developer.mozilla.org/en/docs/Web/CSS/@keyframes for more detailed info.

Here is an update on your fiddle. https://jsfiddle.net/orax9d9u/1/

Apple uses "NSObjectProtocol" instead of "class".

public protocol UIScrollViewDelegate : NSObjectProtocol {
   ...
}

This also works for me and removed the errors I was seeing when trying to implement my own delegate pattern.

if you have many networks attached to you OS, yo must especify one of this network in the bind-addres from my.conf file. an example:

[mysqld]
bind-address = 127.100.10.234

this ip is from a ethX configuration.

If you already have the databinding in place John Myczek answer is complete. If not you have at least 2 options I know of if you want to specify the source of your data. (However I am not sure whether or not this is in line with most guidelines, like MVVM)

The default colours in Gecko, assuming the user hasn't changed their preferences, are:

• standard link: #0000EE (blue)
• visited link: #551A8B (purple)
• active link: #EE0000 (red)

Source

Gecko also provides names for the user's colours; they are -moz-hyperlinktext -moz-visitedhyperlinktext and -moz-activehyperlinktext and they also provide -moz-nativehyperlinktext which is the system link colour.

If you have access to python, this is a helper that will get the yyyy-mm-dd date value for any arbitrary n days ago:

function get_n_days_ago {
  local days=$1
  python -c "import datetime; print (datetime.date.today() - datetime.timedelta(${days})).isoformat()"
}

# today is 2014-08-24

$ get_n_days_ago 1
2014-08-23

$ get_n_days_ago 2
2014-08-22

You can try this fineuploader

It works fine under IE6(and above), Chrome or Firefox

This is a quick workaround (but not recommended) to add this in the plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Which means (according to Apple's documentation):

NSAllowsArbitraryLoads
A Boolean value used to disable App Transport Security for any domains not listed in the NSExceptionDomains dictionary. Listed domains use the settings specified for that domain.

The default value of NO requires the default App Transport Security behaviour for all connections.

I really recommend links:

• Apple's technical note
• WWDC 2015 session 706 (Security and Your Apps) starts around 1:50
• WWDC 2015 session 711 (Networking with NSURLSession)
• Blog post Shipping an App With App Transport Security

which help me understand reasons and all the implications.

The XML (in file Info.plist) below will:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <false/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>PAGE_FOR_WHICH_SETTINGS_YOU_WANT_TO_OVERRIDE</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>

disallow arbitrary calls for all pages, but for PAGE_FOR_WHICH_SETTINGS_YOU_WANT_TO_OVERRIDE will allow that connections use the HTTP protocol.

To the XML above you can add:

<key>NSIncludesSubdomains</key>
<true/>

if you want to allow insecure connections for the subdomains of the specified address.

The best approach is to block all arbitrary loads (set to false) and add exceptions to allow only addresses we know are fine.

For interested readers

2018 Update:

Apple is not recommending switching this off - more information can be found in 207 session WWDC 2018 with more things explained in regards to security

Leaving the original answer for historic reasons and development phase

With newer versions of bundler you can use the clean task:

$ bundle help clean
Usage:
    bundle clean

Options:
    [--dry-run=only print out changes, do not actually clean gems]
    [--force=forces clean even if --path is not set]
    [--no-color=Disable colorization in output]
    -V, [--verbose=Enable verbose output mode]

Cleans up unused gems in your bundler directory
$ bundle clean --dry-run --force
Would have removed actionmailer (3.1.12)
Would have removed actionmailer (3.2.0.rc2)
Would have removed actionpack (3.1.12)
Would have removed actionpack (3.2.0.rc2)
Would have removed activemodel (3.1.12)
...

edit:

This is not recommended if you're using a global gemset (i.e. - all of your projects keep their gems in the same place). There're few ways to keep each project's gems separate, though:

1. rvm gemsets (http://rvm.io/gemsets/basics)
2. bundle install with any of the following options: --deployment or --path=<path> (http://bundler.io/v1.3/man/bundle-install.1.html)

I had the scenario like want to rename the folder and change the build output location, and used below code in the package.json with the latest version

"build": "react-scripts build && mv build ../my_bundles"

My way of avoiding the force push is to create a new branch and continuing work on that new branch and after some stability, remove the old branch that was rebased:

• Rebasing the checked out branch locally
• Branching from the rebased branch to a new branch
• Pushing that branch as a new branch to remote. and deleting the old branch on remote

Immutable, suitable for ReactJS:

Assume:

cosnt arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}];

The updated item is the second and name is changed to Special Person:

const updatedItem = {id:2, name:"Special Person"};

Hint: the lodash has useful tools but now we have some of them on Ecmascript6+, so I just use map function that is existed on both of lodash and ecmascript6+:

const newArr = arr.map(item => item.id === 2 ? updatedItem : item);

simple * rawurlencode the path - path is the part before the "?" - spaces must be encoded as %20 * urlencode the query string - Query string is the part after the "?" -spaces are better encoded as "+" = rawurlencode is more compatible generally

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.

Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.

There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.

You can invoke private method with reflection. Modifying the last bit of the posted code:

Method method = object.getClass().getDeclaredMethod(methodName);
method.setAccessible(true);
Object r = method.invoke(object);

There are a couple of caveats. First, getDeclaredMethod will only find method declared in the current Class, not inherited from supertypes. So, traverse up the concrete class hierarchy if necessary. Second, a SecurityManager can prevent use of the setAccessible method. So, it may need to run as a PrivilegedAction (using AccessController or Subject).

Call getJSONObject() instead of getString(). That will give you a handle on the JSON object in the array and then you can get the property off of the object from there.

For example, to get the property "value" from a List<SomeClass> where SomeClass has a String getValue() and setValue(String value):

JSONObject obj = new JSONObject();
List<SomeClass> sList = new ArrayList<SomeClass>();

SomeClass obj1 = new SomeClass();
obj1.setValue("val1");
sList.add(obj1);

SomeClass obj2 = new SomeClass();
obj2.setValue("val2");
sList.add(obj2);

obj.put("list", sList);

JSONArray jArray = obj.getJSONArray("list");
for(int ii=0; ii < jArray.length(); ii++)
  System.out.println(jArray.getJSONObject(ii).getString("value"));

The current best practice is to configure Jackson within the application.yml (or properties) file.

Example:

spring:
  jackson:
    property-naming-strategy: SNAKE_CASE

If you have more complex configuration requirements, you can also configure Jackson programmatically.

import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;

@Configuration
public class JacksonConfiguration {

    @Bean
    public Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder() {
        return new Jackson2ObjectMapperBuilder()
                .propertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
        // insert other configurations
    }

} 

I don't know of a platform independent way of doing it, but under Windows, if you use the msvcrt module, you can use its getch function:

import msvcrt
c = msvcrt.getch()
print 'you entered', c

mscvcrt also includes the non-blocking kbhit() function to see if a key was pressed without waiting (not sure if there's a corresponding curses function). Under UNIX, there is the curses package, but not sure if you can use it without using it for all of the screen output. This code works under UNIX:

import curses
stdscr = curses.initscr()
c = stdscr.getch()
print 'you entered', chr(c)
curses.endwin()

Note that curses.getch() returns the ordinal of the key pressed so to make it have the same output I had to cast it.

Exclude all from subfolders works like this (version 2019)

include

./db

exclude

./db/*

What is the line? You can just have arguments on the next line without any problems:

a = dostuff(blahblah1, blahblah2, blahblah3, blahblah4, blahblah5, 
            blahblah6, blahblah7)

Otherwise you can do something like this:

if (a == True and
    b == False):

or with explicit line break:

if a == True and \
   b == False:

Check the style guide for more information.

Using parentheses, your example can be written over multiple lines:

a = ('1' + '2' + '3' +
    '4' + '5')

The same effect can be obtained using explicit line break:

a = '1' + '2' + '3' + \
    '4' + '5'

Note that the style guide says that using the implicit continuation with parentheses is preferred, but in this particular case just adding parentheses around your expression is probably the wrong way to go.

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

    ... 6 more

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

/**
 * Document my Jenkinsfile's overall purpose here
 */

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

HTTP Servers tend to reject old browsers and systems.

The page Tech Blog (wh): Most Common User Agents reflects the user-agent property of your current browser in section "Your user agent is:", which can be applied to set the request property "User-Agent" of a java.net.URLConnection or the system property "http.agent".

For IE 7 & 8 (and other browsers without CSS3 support not including IE6) you can use the following to get the 2nd and 3rd children:

2nd Child:

td:first-child + td

3rd Child:

td:first-child + td + td

Then simply add another + td for each additional child you wish to select.

If you want to support IE6 that can be done too! You simply need to use a little javascript (jQuery in this example):

$(function() {
    $('td:first-child').addClass("firstChild");
    $(".table-class tr").each(function() {
        $(this).find('td:eq(1)').addClass("secondChild");
        $(this).find('td:eq(2)').addClass("thirdChild");
    });
});

Then in your css you simply use those class selectors to make whatever changes you like:

table td.firstChild { /*stuff here*/ }
table td.secondChild { /*stuff to apply to second td in each row*/ }

For iOS 13, building on the answers by mythicalcoder and bobbyrehm:

In iOS 13, if you are creating your own window to present the alert in, you are required to hold a strong reference to that window or else your alert won't be displayed because the window will be immediately deallocated when its reference exits scope.

Furthermore, you'll need to set the reference to nil again after the alert is dismissed in order to remove the window to continue to allow user interaction on the main window below it.

You can create a UIViewController subclass to encapsulate the window memory management logic:

class WindowAlertPresentationController: UIViewController {

    // MARK: - Properties

    private lazy var window: UIWindow? = UIWindow(frame: UIScreen.main.bounds)
    private let alert: UIAlertController

    // MARK: - Initialization

    init(alert: UIAlertController) {

        self.alert = alert
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder aDecoder: NSCoder) {

        fatalError("This initializer is not supported")
    }

    // MARK: - Presentation

    func present(animated: Bool, completion: (() -> Void)?) {

        window?.rootViewController = self
        window?.windowLevel = UIWindow.Level.alert + 1
        window?.makeKeyAndVisible()
        present(alert, animated: animated, completion: completion)
    }

    // MARK: - Overrides

    override func dismiss(animated flag: Bool, completion: (() -> Void)? = nil) {

        super.dismiss(animated: flag) {
            self.window = nil
            completion?()
        }
    }
}

You can use this as is, or if you want a convenience method on your UIAlertController, you can throw it in an extension:

extension UIAlertController {

    func presentInOwnWindow(animated: Bool, completion: (() -> Void)?) {

        let windowAlertPresentationController = WindowAlertPresentationController(alert: self)
        windowAlertPresentationController.present(animated: animated, completion: completion)
    }
}

You can use an androidx.cardview.widget.CardView like so:

<androidx.cardview.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"       
        app:cardCornerRadius="@dimen/dimen_4"
        app:cardElevation="@dimen/dimen_4"
        app:contentPadding="@dimen/dimen_10">

       ...

</androidx.cardview.widget.CardView>

OR

shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="#f6eef1" />

    <stroke
        android:width="2dp"
        android:color="#000000" />

    <padding
        android:bottom="5dp"
        android:left="5dp"
        android:right="5dp"
        android:top="5dp" />

    <corners android:radius="5dp" />

</shape>

and inside you layout

<LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape">

        ...

</LinearLayout>

npm install installs dependencies into the node_modules/ directory, for the node project you're working on. You can call install on another node.js project (module), to install it as a dependency for your project.

npm run build does nothing unless you specify what "build" does in your package.json file. It lets you perform any necessary building/prep tasks for your project, prior to it being used in another project.

npm build is an internal command and is called by link and install commands, according to the documentation for build:

This is the plumbing command called by npm link and npm install.

You will not be calling npm build normally as it is used internally to build native C/C++ Node addons using node-gyp.

You can also run docker build with -f option

docker build -t ubuntu-test:latest -f Dockerfile.custom .

This is a simple one line way to do it:

    try {
        URL url = new URL("http://....");
        Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
    } catch(IOException e) {
        System.out.println(e);
    }

Once you have put the values into the JSONObject then put the JSONObject into the JSONArray staright after.

Something like this maybe:

jsonObj.put("value1", 1);
jsonObj.put("value2", 900);
jsonObj.put("value3", 1368349);
jsonArray.put(jsonObj);

Then create new JSONObject, put the other values into it and add it to the JSONArray:

jsonObj.put("value1", 2);
jsonObj.put("value2", 1900);
jsonObj.put("value3", 136856);
jsonArray.put(jsonObj);

Generally it means that you are providing an index for which a list element does not exist.

E.g, if your list was [1, 3, 5, 7], and you asked for the element at index 10, you would be well out of bounds and receive an error, as only elements 0 through 3 exist.

This worked for me :

select option {
   color: black;
}
select:not(:checked) {
   color: gray;
}

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath.

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.

If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.

For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.

If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.

While the existing answers are fine, I'd like to point out one approach which doesn't work:

public static string DontUseThisToCollapseSpaces(string text)
{
    while (text.IndexOf("  ") != -1)
    {
        text = text.Replace("  ", " ");
    }
    return text;
}

This can loop forever. Anyone care to guess why? (I only came across this when it was asked as a newsgroup question a few years ago... someone actually ran into it as a problem.)

Make sure you switch the SHELL first:

SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]

RUN [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 
RUN Invoke-WebRequest -UseBasicParsing -Uri  'https://github.com/git-for-windows/git/releases/download/v2.25.1.windows.1/Git-2.25.1-64-bit.exe' -OutFile 'outfile.exe'

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

In Laravel 5.3+ use

$users->links('view.name')

In Laravel 5.0 - 5.2 instead of

$users->render()

use

@include('pagination.default', ['paginator' => $users])

views/pagination/default.blade.php

@if ($paginator->lastPage() > 1)
<ul class="pagination">
    <li class="{{ ($paginator->currentPage() == 1) ? ' disabled' : '' }}">
        <a href="{{ $paginator->url(1) }}">Previous</a>
    </li>
    @for ($i = 1; $i <= $paginator->lastPage(); $i++)
        <li class="{{ ($paginator->currentPage() == $i) ? ' active' : '' }}">
            <a href="{{ $paginator->url($i) }}">{{ $i }}</a>
        </li>
    @endfor
    <li class="{{ ($paginator->currentPage() == $paginator->lastPage()) ? ' disabled' : '' }}">
        <a href="{{ $paginator->url($paginator->currentPage()+1) }}" >Next</a>
    </li>
</ul>
@endif

That's it.

If you have a lot of pages, use this template:

views/pagination/limit_links.blade.php

<?php
// config
$link_limit = 7; // maximum number of links (a little bit inaccurate, but will be ok for now)
?>

@if ($paginator->lastPage() > 1)
    <ul class="pagination">
        <li class="{{ ($paginator->currentPage() == 1) ? ' disabled' : '' }}">
            <a href="{{ $paginator->url(1) }}">First</a>
         </li>
        @for ($i = 1; $i <= $paginator->lastPage(); $i++)
            <?php
            $half_total_links = floor($link_limit / 2);
            $from = $paginator->currentPage() - $half_total_links;
            $to = $paginator->currentPage() + $half_total_links;
            if ($paginator->currentPage() < $half_total_links) {
               $to += $half_total_links - $paginator->currentPage();
            }
            if ($paginator->lastPage() - $paginator->currentPage() < $half_total_links) {
                $from -= $half_total_links - ($paginator->lastPage() - $paginator->currentPage()) - 1;
            }
            ?>
            @if ($from < $i && $i < $to)
                <li class="{{ ($paginator->currentPage() == $i) ? ' active' : '' }}">
                    <a href="{{ $paginator->url($i) }}">{{ $i }}</a>
                </li>
            @endif
        @endfor
        <li class="{{ ($paginator->currentPage() == $paginator->lastPage()) ? ' disabled' : '' }}">

• utf8 is MySQL's older, flawed implementation of UTF-8 which is in the process of being deprecated.
• utf8mb4 is what they named their fixed UTF-8 implementation, and is what you should use right now.

In their flawed version, only characters in the first 64k character plane - the basic multilingual plane - work, with other characters considered invalid. The code point values within that plane - 0 to 65535 (some of which are reserved for special reasons) can be represented by multi-byte encodings in UTF-8 of up to 3 bytes, and MySQL's early version of UTF-8 arbitrarily decided to set that as a limit. At no point was this limitation a correct interpretation of the UTF-8 rules, because at no point was UTF-8 defined as only allowing up to 3 bytes per character. In fact, the earliest definitions of UTF-8 defined it as having up to 6 bytes (since revised to 4). MySQL's original version was always arbitrarily crippled.

Back when MySQL released this, the consequences of this limitation weren't too bad as most Unicode characters were in that first plane. Since then, more and more newly defined character ranges have been added to Unicode with values outside that first plane. Unicode itself defines 17 planes, though so far only 7 of these are used.

In an effort not to break old code making any particular assumptions, MySQL retained the broken implementation and called the newer, fixed version utf8mb4. This has led to some confusion with the name being misinterpreted as if it's some kind of extension to UTF-8 or alternative form of UTF-8, rather than MySQL's implementation of the true UTF-8.

Future versions of MySQL will eventually phase out the older version, and for now it can be considered deprecated. For the foreseeable future you need to use utf8mb4 to ensure correct UTF-8 encoding. After sufficient time has passed, the current utf8 will be removed, and at some future date utf8 will rise again, this time referring to the fixed version, though utf8mb4 will continue to unambiguously refer to the fixed version.

I was able to fix this in Android Studio 0.2.0 by changing API from API 18: Android 4.3 to API 17: Android 4.2.2

This is under the Android icon menu in the top right of the design window.

This was a solution from http://www.hankcs.com/program/mobiledev/idea-this-version-of-the-rendering-library-is-more-recent-than-your-version-of-intellij-idea-please-update-intellij-idea.html.This required a Google translation into English since it was in another language.

Hope it helps.

The fact that the sort values in the OP are integers isn't relevant to the question per se. In other words, the accepted answer would work if the sort value was text. I bring this up to also point out that the sort can be modified during the sort (for example, to account for upper and lower case).

>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: x[1])
[(148, 'ABC'), (221, 'DEF'), (121, 'abc'), (231, 'def')]
>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: str.lower(x[1]))
[(121, 'abc'), (148, 'ABC'), (231, 'def'), (221, 'DEF')]

Select * from table where date > 'Today's date(mm/dd/yyyy)'

You can also add time in the single quotes(00:00:00AM)

For example:

Select * from Receipts where Sales_date > '08/28/2014 11:59:59PM'

1) Graphically intuitive way you can generate Gaussian random numbers is by using something similar to the Monte Carlo method. You would generate a random point in a box around the Gaussian curve using your pseudo-random number generator in C. You can calculate if that point is inside or underneath the Gaussian distribution using the equation of the distribution. If that point is inside the Gaussian distribution, then you have got your Gaussian random number as the x value of the point.

This method isn't perfect because technically the Gaussian curve goes on towards infinity, and you couldn't create a box that approaches infinity in the x dimension. But the Guassian curve approaches 0 in the y dimension pretty fast so I wouldn't worry about that. The constraint of the size of your variables in C may be more of a limiting factor to your accuracy.

2) Another way would be to use the Central Limit Theorem which states that when independent random variables are added, they form a normal distribution. Keeping this theorem in mind, you can approximate a Gaussian random number by adding a large amount of independent random variables.

These methods aren't the most practical, but that is to be expected when you don't want to use a preexisting library. Keep in mind this answer is coming from someone with little or no calculus or statistics experience.

One way is to run the program in a subshell, and communicate with the subshell through a named pipe with the read command. This way you can check the exit status of the process being run and communicate this back through the pipe.

Here's an example of timing out the yes command after 3 seconds. It gets the PID of the process using pgrep (possibly only works on Linux). There is also some problem with using a pipe in that a process opening a pipe for read will hang until it is also opened for write, and vice versa. So to prevent the read command hanging, I've "wedged" open the pipe for read with a background subshell. (Another way to prevent a freeze to open the pipe read-write, i.e. read -t 5 <>finished.pipe - however, that also may not work except with Linux.)

rm -f finished.pipe
mkfifo finished.pipe

{ yes >/dev/null; echo finished >finished.pipe ; } &
SUBSHELL=$!

# Get command PID
while : ; do
    PID=$( pgrep -P $SUBSHELL yes )
    test "$PID" = "" || break
    sleep 1
done

# Open pipe for writing
{ exec 4>finished.pipe ; while : ; do sleep 1000; done } &  

read -t 3 FINISHED <finished.pipe

if [ "$FINISHED" = finished ] ; then
  echo 'Subprocess finished'
else
  echo 'Subprocess timed out'
  kill $PID
fi

rm finished.pipe

Go to System Properties > Advanced > Enviroment Variables and look under System variables

First, create/set your JAVA_HOME variable

Even though Eclipse doesn't consult the JAVA_HOME variable, it's still a good idea to set it. See How do I run Eclipse? for more information.

If you have not created and/or do not see JAVA_HOME under the list of System variables, do the following:

1. Click New... at the very bottom
2. For Variable name, type JAVA_HOME exactly
3. For Variable value, this could be different depending on what bits your computer and java are.
   • If both your computer and java are 64-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, type C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, type C:\Program Files (x86)\Java\jdk1.8.0_60

If you have created and/or do see JAVA_HOME, do the following:

1. Click on the row under System variables that you see JAVA_HOME in
2. Click Edit... at the very bottom
3. For Variable value, change it to what was stated in #3 above based on java's and your computer's bits. To repeat:
   • If both your computer and java are 64-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If both your computer and java are 32-bit, change it to C:\Program Files\Java\jdk1.8.0_60
   • If your computer is 64-bit, but your java is 32-bit, change it to C:\Program Files (x86)\Java\jdk1.8.0_60

Next, add to your PATH variable

1. Click on the row under System variables with PATH in it
2. Click Edit... at the very bottom
3. If you have a newer version of windows:
   • Click New
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60 depending on the bits of your computer and java (see above ^).
   • Press Enter and Click New again.
   • Type in C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre depending on the bits of your computer and java (see above again ^).
   • Press Enter and press OK on all of the related windows
4. If you have an older version of windows
   • In the Variable value textbox (or something similar) drag the cursor all the way to the very end
   • Add a semicolon (;) if there isn't one already
   • C:\Program Files (x86)\Java\jdk1.8.0_60 OR C:\Program Files\Java\jdk1.8.0_60
   • Add another semicolon (;)
   • C:\Program Files (x86)\Java\jdk1.8.0_60\jre OR C:\Program Files\Java\jdk1.8.0_60\jre

Changing eclipse.ini

1. Find your eclipse.ini file and copy-paste it in the same directory (should be named eclipse(1).ini)
2. Rename eclipse.ini to eclipse.ini.old just in case something goes wrong
3. Rename eclipse(1).ini to eclipse.ini

4. Open your newly-renamed eclipse.ini and replace all of it with this:

   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
   -product
   org.eclipse.epp.package.java.product
   --launcher.defaultAction
   openFile
   --launcher.XXMaxPermSize
   256M
   -showsplash
   org.eclipse.platform
   --launcher.XXMaxPermSize
   256m
   --launcher.defaultAction
   openFile
   -vm
   C:\Program Files\Java\jdk1.8.0_60\bin\javaw.exe
   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms40m
   -Xmx1024m
   

XXMaxPermSize may be deprecated, so it might not work. If eclipse still does not launch, do the following:

1. Delete the newer eclipse.ini
2. Rename eclipse.ini.old to eclipse.ini
3. Open command prompt
4. type in eclipse -vm C:\Program Files (x86)\Java\jdk1.8.0_60\bin\javaw.exe

If the problem remains

Try updating your eclipse and java to the latest version. 8u60 (1.8.0_60) is not the latest version of java. Sometimes, the latest version of java doesn't work with older versions of eclipse and vice versa. Otherwise, leave a comment if you're still having problems. You could also try a fresh reinstallation of Java.

If you're on linux then you can grab the guest processes with

ps axuw | grep vmware-vmx

As @Dubas pointed out, you should be able to pick out the errant process by the path name to the VMD

Add display:block; to the table's css. (in other words.. tell the table to act like a block element rather than a table.)

fiddle here

Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).

Instead, use a List:

ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.

Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:

String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.

I know there are a few configurations to use the static contents, but my solution is that I just create a bulk web-application folder within your tomcat. This "bulk webapp" is only serving all the static-contents without serving apps. This is pain-free and easy solution for serving static contents to your actual spring webapp.

For example, I'm using two webapp folders on my tomcat.

1. springapp: it is running only spring web application without static-contents like imgs, js, or css. (dedicated for spring apps.)
2. resources: it is serving only the static contents without JSP, servlet, or any sort of java web application. (dedicated for static-contents)

If I want to use javascript, I simply add the URI for my javascript file.

EX> /resources/path/to/js/myjavascript.js

For static images, I'm using the same method.

EX> /resources/path/to/img/myimg.jpg

Last, I put "security-constraint" on my tomcat to block the access to actual directory. I put "nobody" user-roll to the constraint so that the page generates "403 forbidden error" when people tried to access the static-contents path.

So far it works very well for me. I also noticed that many popular websites like Amazon, Twitter, and Facebook they are using different URI for serving static-contents. To find out this, just right click on any static content and check their URI.

ISO IEC 14882-2003

9 Classes

§3

A structure is a class defined with the class-key struct; its members and base classes (clause 10) are public by default (clause 11).

You can implement an OnClickListener via OnTouchListener:

webView.setOnTouchListener(new View.OnTouchListener() {

        public final static int FINGER_RELEASED = 0;
        public final static int FINGER_TOUCHED = 1;
        public final static int FINGER_DRAGGING = 2;
        public final static int FINGER_UNDEFINED = 3;

        private int fingerState = FINGER_RELEASED;


        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {

            switch (motionEvent.getAction()) {

                case MotionEvent.ACTION_DOWN:
                    if (fingerState == FINGER_RELEASED) fingerState = FINGER_TOUCHED;
                    else fingerState = FINGER_UNDEFINED;
                    break;

                case MotionEvent.ACTION_UP:
                    if(fingerState != FINGER_DRAGGING) {
                        fingerState = FINGER_RELEASED;

                        // Your onClick codes

                    }
                    else if (fingerState == FINGER_DRAGGING) fingerState = FINGER_RELEASED;
                    else fingerState = FINGER_UNDEFINED;
                    break;

                case MotionEvent.ACTION_MOVE:
                    if (fingerState == FINGER_TOUCHED || fingerState == FINGER_DRAGGING) fingerState = FINGER_DRAGGING;
                    else fingerState = FINGER_UNDEFINED;
                    break;

                default:
                    fingerState = FINGER_UNDEFINED;

            }

            return false;
        }
    });

You cannot store arrays in a vector or any other container. The type of the elements to be stored in a container (called the container's value type) must be both copy constructible and assignable. Arrays are neither.

You can, however, use an array class template, like the one provided by Boost, TR1, and C++0x:

std::vector<std::array<double, 4> >

(You'll want to replace std::array with std::tr1::array to use the template included in C++ TR1, or boost::array to use the template from the Boost libraries. Alternatively, you can write your own; it's quite straightforward.)

I know this is an old topic, but I think it is still relevant, and would like to share an implementation of an array comparison method which I feel strikes the right balance between performance and elegance.

static bool CollectionEquals<T>(ICollection<T> a, ICollection<T> b, IEqualityComparer<T> comparer = null)
{
    return ReferenceEquals(a, b) || a != null && b != null && a.Count == b.Count && a.SequenceEqual(b, comparer);
}

The idea here is to check for all of the early out conditions first, then fall back on SequenceEqual. It also avoids doing extra branching and instead relies on boolean short-circuit to avoid unecessary execution. I also feel it looks clean and is easy to understand.

Also, by using ICollection for the parameters, it will work with more than just arrays.

Check whether the port number in file Web.config of your webpage is the same as the one that is hosted on IIS.

Here is a full example of what you are looking for:

<html>
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script>
        $( document ).ready(function() {
            $("#providersFormElementsTable").html("<tr><td>Nickname</td><td><input type='text' id='nickname' name='nickname'></td></tr><tr><td>CA Number</td><td><input type='text' id='account' name='account'></td></tr>");
        });
    </script>
</head>

<body>
    <table border="0" cellpadding="0" width="100%" id='providersFormElementsTable'> </table>
</body>

Try This:

In strings.xml add your title and subtitle...

ActionBar ab = getActionBar();
ab.setTitle(getResources().getString(R.string.myTitle));
ab.setSubtitle(getResources().getString(R.string.mySubTitle));

LayoutInflater.from(context).inflate(R.layout.row_payment_gateway_item, null);

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

Check the following entry in your Vagrantfile

Every Vagrant development environment requires a box.
You can search for boxes at https://vagrantcloud.com/search.
  config.vm.box = "base"

This is the default file setting which is created with vagrant init command. But what you need to do is do initialise vagrant environment with an OS box. For instance $vagrant init centos/7. And the Vagrantfile will look something like this:

Every Vagrant development environment requires a box.
You can search for boxes at https://vagrantcloud.com/search.
  config.vm.box = "centos/7"

This will resolve the error of not found base when doing a vagrant up.

1. Go to Sql Server Management Studio >
2. Object Explorer >
3. Databases >
4. Choose and expand your Database.
5. Under your database right click on "Database Diagrams" and select "New Database Diagram".
6. It will a open a new window. Choose tables to include in ER-Diagram (to select multiple tables press "ctrl" or "shift" button and select tables).
7. Click add.
8. Wait for it to complete. Done!

You can save generated diagram for future use.

Time for another solution:

function getMaxOccurrence(arr) {
    var o = {}, maxCount = 0, maxValue, m;
    for (var i=0, iLen=arr.length; i<iLen; i++) {
        m = arr[i];

        if (!o.hasOwnProperty(m)) {
            o[m] = 0;
        }
        ++o[m];

        if (o[m] > maxCount) {
            maxCount = o[m];
            maxValue = m;
        }
    }
    return maxValue;
}

If brevity matters (it doesn't), then:

function getMaxOccurrence(a) {
    var o = {}, mC = 0, mV, m;
    for (var i=0, iL=a.length; i<iL; i++) {
        m = a[i];
        o.hasOwnProperty(m)? ++o[m] : o[m] = 1;
        if (o[m] > mC) mC = o[m], mV = m;
    }
    return mV;
}

If non–existent members are to be avoided (e.g. sparse array), an additional hasOwnProperty test is required:

function getMaxOccurrence(a) {
    var o = {}, mC = 0, mV, m;
    for (var i=0, iL=a.length; i<iL; i++) {
        if (a.hasOwnProperty(i)) {
            m = a[i];
            o.hasOwnProperty(m)? ++o[m] : o[m] = 1;
            if (o[m] > mC) mC = o[m], mV = m;
        }
    }
    return mV;
}

getMaxOccurrence([,,,,,1,1]); // 1

Other answers here will return undefined.

Additionally, you can just sleep:

sleep(10)

Since the UITests run in another process, this works. I don’t know how advisable it is, but it works.

Given the proliferation of different ways to read an Excel file in R and the plethora of answers here, I thought I'd try to shed some light on which of the options mentioned here perform the best (in a few simple situations).

I myself have been using xlsx since I started using R, for inertia if nothing else, and I recently noticed there doesn't seem to be any objective information about which package works better.

Any benchmarking exercise is fraught with difficulties as some packages are sure to handle certain situations better than others, and a waterfall of other caveats.

That said, I'm using a (reproducible) data set that I think is in a pretty common format (8 string fields, 3 numeric, 1 integer, 3 dates):

set.seed(51423)
data.frame(
  str1 = sample(sprintf("%010d", 1:NN)), #ID field 1
  str2 = sample(sprintf("%09d", 1:NN)),  #ID field 2
  #varying length string field--think names/addresses, etc.
  str3 = 
    replicate(NN, paste0(sample(LETTERS, sample(10:30, 1L), TRUE),
                         collapse = "")),
  #factor-like string field with 50 "levels"
  str4 = sprintf("%05d", sample(sample(1e5, 50L), NN, TRUE)),
  #factor-like string field with 17 levels, varying length
  str5 = 
    sample(replicate(17L, paste0(sample(LETTERS, sample(15:25, 1L), TRUE),
                                 collapse = "")), NN, TRUE),
  #lognormally distributed numeric
  num1 = round(exp(rnorm(NN, mean = 6.5, sd = 1.5)), 2L),
  #3 binary strings
  str6 = sample(c("Y","N"), NN, TRUE),
  str7 = sample(c("M","F"), NN, TRUE),
  str8 = sample(c("B","W"), NN, TRUE),
  #right-skewed integer
  int1 = ceiling(rexp(NN)),
  #dates by month
  dat1 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  dat2 = 
    sample(seq(from = as.Date("2005-12-31"), 
               to = as.Date("2015-12-31"), by = "month"),
           NN, TRUE),
  num2 = round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L),
  #date by day
  dat3 = 
    sample(seq(from = as.Date("2015-06-01"), 
               to = as.Date("2015-07-15"), by = "day"),
           NN, TRUE),
  #lognormal numeric that can be positive or negative
  num3 = 
    (-1) ^ sample(2, NN, TRUE) * round(exp(rnorm(NN, mean = 6, sd = 1.5)), 2L)
)

I then wrote this to csv and opened in LibreOffice and saved it as an .xlsx file, then benchmarked 4 of the packages mentioned in this thread: xlsx, openxlsx, readxl, and gdata, using the default options (I also tried a version of whether or not I specify column types, but this didn't change the rankings).

I'm excluding RODBC because I'm on Linux; XLConnect because it seems its primary purpose is not reading in single Excel sheets but importing entire Excel workbooks, so to put its horse in the race on only its reading capabilities seems unfair; and xlsReadWrite because it is no longer compatible with my version of R (seems to have been phased out).

I then ran benchmarks with NN=1000L and NN=25000L (resetting the seed before each declaration of the data.frame above) to allow for differences with respect to Excel file size. gc is primarily for xlsx, which I've found at times can create memory clogs. Without further ado, here are the results I found:

1,000-Row Excel File

benchmark1k <-
  microbenchmark(times = 100L,
                 xlsx = {xlsx::read.xlsx2(fl, sheetIndex=1); invisible(gc())},
                 openxlsx = {openxlsx::read.xlsx(fl); invisible(gc())},
                 readxl = {readxl::read_excel(fl); invisible(gc())},
                 gdata = {gdata::read.xls(fl); invisible(gc())})

# Unit: milliseconds
#      expr       min        lq      mean    median        uq       max neval
#      xlsx  194.1958  199.2662  214.1512  201.9063  212.7563  354.0327   100
#  openxlsx  142.2074  142.9028  151.9127  143.7239  148.0940  255.0124   100
#    readxl  122.0238  122.8448  132.4021  123.6964  130.2881  214.5138   100
#     gdata 2004.4745 2042.0732 2087.8724 2062.5259 2116.7795 2425.6345   100

So readxl is the winner, with openxlsx competitive and gdata a clear loser. Taking each measure relative to the column minimum:

#       expr   min    lq  mean median    uq   max
# 1     xlsx  1.59  1.62  1.62   1.63  1.63  1.65
# 2 openxlsx  1.17  1.16  1.15   1.16  1.14  1.19
# 3   readxl  1.00  1.00  1.00   1.00  1.00  1.00
# 4    gdata 16.43 16.62 15.77  16.67 16.25 11.31

We see my own favorite, xlsx is 60% slower than readxl.

25,000-Row Excel File

Due to the amount of time it takes, I only did 20 repetitions on the larger file, otherwise the commands were identical. Here's the raw data:

# Unit: milliseconds
#      expr        min         lq       mean     median         uq        max neval
#      xlsx  4451.9553  4539.4599  4738.6366  4762.1768  4941.2331  5091.0057    20
#  openxlsx   962.1579   981.0613   988.5006   986.1091   992.6017  1040.4158    20
#    readxl   341.0006   344.8904   347.0779   346.4518   348.9273   360.1808    20
#     gdata 43860.4013 44375.6340 44848.7797 44991.2208 45251.4441 45652.0826    20

Here's the relative data:

#       expr    min     lq   mean median     uq    max
# 1     xlsx  13.06  13.16  13.65  13.75  14.16  14.13
# 2 openxlsx   2.82   2.84   2.85   2.85   2.84   2.89
# 3   readxl   1.00   1.00   1.00   1.00   1.00   1.00
# 4    gdata 128.62 128.67 129.22 129.86 129.69 126.75

So readxl is the clear winner when it comes to speed. gdata better have something else going for it, as it's painfully slow in reading Excel files, and this problem is only exacerbated for larger tables.

Two draws of openxlsx are 1) its extensive other methods (readxl is designed to do only one thing, which is probably part of why it's so fast), especially its write.xlsx function, and 2) (more of a drawback for readxl) the col_types argument in readxl only (as of this writing) accepts some nonstandard R: "text" instead of "character" and "date" instead of "Date".

DELETE TableA instead of TRUNCATE TableA? A common misconception is that they do the same thing. Not so. In fact, there are many differences between the two.

DELETE is a logged operation on a per row basis. This means that the deletion of each row gets logged and physically deleted.

You can DELETE any row that will not violate a constraint, while leaving the foreign key or any other contraint in place.

TRUNCATE is also a logged operation, but in a different way. TRUNCATE logs the deallocation of the data pages in which the data exists. The deallocation of data pages means that your data rows still actually exist in the data pages, but the extents have been marked as empty for reuse. This is what makes TRUNCATE a faster operation to perform over DELETE.

You cannot TRUNCATE a table that has any foreign key constraints. You will have to remove the contraints, TRUNCATE the table, and reapply the contraints.

TRUNCATE will reset any identity columns to the default seed value.

Try This,

npm config delete http-proxy

npm config delete https-proxy

npm config rm proxy

npm config rm https-proxy

set HTTP_PROXY=null

set HTTPS_PROXY=null

Check your apache error log. I had this error "[error] (OS 5)Access is denied. : could not open transfer log file C:/wamp/logs/access.log. Unable to open logs" Then I rename my "access.log" to other name, you can delete if you don't need/never see your access log. Then restart your apache service. This happen because the file size too big. I think if you trying to open this file using notepad, it will not open, I tried to open that before. Hope it help.

Just use exception.ToString()

http://msdn.microsoft.com/en-us/library/system.exception.tostring.aspx

The default implementation of ToString obtains the name of the class that threw the current exception, the message, the result of calling ToString on the inner exception, and the result of calling Environment.StackTrace. If any of these members is null, its value is not included in the returned string.

If there is no error message or if it is an empty string (""), then no error message is returned. The name of the inner exception and the stack trace are returned only if they are not null.

exception.ToString() will also call .ToString() on that exception's inner exception, and so on...

For me, I fixed this error by editing the .bashrc file, adding exports. Add after the initial comments.

Add language support.

export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_TYPE=en_US.UTF-8

You need to do the following steps:

1. Open your ssh client or terminal if you are using Linux.
2. Locate your private key file and change your directory.
   cd <path to your .pem file>
3. Execute below commands:
   chmod 400 <filename>.pem
ssh -i <filename>.pem ubuntu@<ipaddress.com>

If ubuntu user is not working then try with ec2-user.

Cleaner way, exploit shortcut evaluation of shell logical operators. Right side of the operator is executed only if left side is true.

[ ! -d /home/mlzboy/b2c2/shared/db ] && mkdir -p /home/mlzboy/b2c2/shared/db

eg:

MyPackageName is com.example.demo

MyActivityName is com.example.test.MainActivity

adb shell am start -n com.example.demo/com.example.test.MainActivity

Set up a constructor in your entity and set the default value there.

As olliej said, using the navigator.onLine browser property is preferable than sending network requests and, accordingly with developer.mozilla.org/En/Online_and_offline_events, it is even supported by old versions of Firefox and IE.

Recently, the WHATWG has specified the addition of the online and offline events, in case you need to react on navigator.onLine changes.

Please also pay attention to the link posted by Daniel Silveira which points out that relying on those signal/property for syncing with the server is not always a good idea.

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

Here is the solution:

1. Login to DB;
2. Run a command show full processlist;to get the process id with status and query itself which causes the database hanging;
3. Select the process id and run a command KILL <pid>; to kill that process.

Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:

1. Login to MySQL;
2. Run a query Select concat('KILL ',id,';') from information_schema.processlist where user='user'; to print all processes with KILL command;
3. Copy the query result, paste and remove a pipe | sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.

The rolling mean returns a Series you only have to add it as a new column of your DataFrame (MA) as described below.

For information, the rolling_mean function has been deprecated in pandas newer versions. I have used the new method in my example, see below a quote from the pandas documentation.

Warning Prior to version 0.18.0, pd.rolling_*, pd.expanding_*, and pd.ewm* were module level functions and are now deprecated. These are replaced by using the Rolling, Expanding and EWM. objects and a corresponding method call.

df['MA'] = df.rolling(window=5).mean()

print(df)
#             Value    MA
# Date

Sun's java 1.4 has the following arguments to control memory size:

-Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:

           -Xms6291456
           -Xms6144k
           -Xms6m

-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:

           -Xmx83886080
           -Xmx81920k
           -Xmx80m

Java 5 and 6 have some more. See http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp

using import matplotlib.pyplot as plt

Method 1: specify the fontsize when calling legend (repetitive)

plt.legend(fontsize=20) # using a size in points
plt.legend(fontsize="x-large") # using a named size

With this method you can set the fontsize for each legend at creation (allowing you to have multiple legends with different fontsizes). However, you will have to type everything manually each time you create a legend.

(Note: @Mathias711 listed the available named fontsizes in his answer)

Method 2: specify the fontsize in rcParams (convenient)

plt.rc('legend',fontsize=20) # using a size in points
plt.rc('legend',fontsize='medium') # using a named size

With this method you set the default legend fontsize, and all legends will automatically use that unless you specify otherwise using method 1. This means you can set your legend fontsize at the beginning of your code, and not worry about setting it for each individual legend.

If you use a named size e.g. 'medium', then the legend text will scale with the global font.size in rcParams. To change font.size use plt.rc(font.size='medium')

Try this code:

return em.createNativeQuery("{call getEmployeeDetails(?,?)}",
                               EmployeeDetails.class)           
                               .setParameter(1, employeeId)
                               .setParameter(2, companyId).getResultList();

Don't use Holo theme and the Actionbar will disappear. This code is working for me on API 8+, with support lib v7:

<style name="NoActionBar" parent="@style/Theme.AppCompat.Light">
<item name="android:windowNoTitle">true</item>
</style>

set that theme for your activity:

<activity android:theme="@style/NoActionBar" ... />

and in your activity class.

It works even when it extends ActionBarActivity.

After changing permissions of folder in which I was cloning, it worked:

sudo chown -R ubuntu:ubuntu /var/projects

how about

let isnum = /^\d+$/.test(val);

You can use String.Format:

DateTime d = DateTime.Now;
string str = String.Format("{0:00}/{1:00}/{2:0000} {3:00}:{4:00}:{5:00}.{6:000}", d.Month, d.Day, d.Year, d.Hour, d.Minute, d.Second, d.Millisecond);
// I got this result: "02/23/2015 16:42:38.234"

Actually, as far as I know, nginx would show an empty message and it wouldn't actually restart if the configuration is bad.

The only way to screw it up is by doing an nginx stop and then start again. It would succeed to stop, but fail to start.

Here is a alternative solution in Python 3.0 which allows non-string list items:

>>> alist = ['a', 1, (2, 'b')]

• a standard way

  >>> ", ".join(map(str, alist))
  "a, 1, (2, 'b')"
  

• the alternative solution

  >>> import io
  >>> s = io.StringIO()
  >>> print(*alist, file=s, sep=', ', end='')
  >>> s.getvalue()
  "a, 1, (2, 'b')"
  

NOTE: The space after comma is intentional.

I got this message when I tried to git clone a repo that was not mine. The fix was to fork and then clone.

Google Brings me here. The favourite answers don't help me. I've now solved it, so maybe this will help someone else. Problem: after UPDATE of XAMPP to a new version I get the message "MySQL WILL NOT start without the configured ports free!".

However, I only have 1 instance of mysqld running.

It seems that the control panel is not as clever as it looks. As far as I can tell, the single instance of mysqld is the new one i've just updated to, but running as a 'service'. The control panel then tries to start it, and instead of realising its already running, It assumes its another service and reports the error.

Probable cause: The uninstaller failed to remove the autostart property from the mysql service, so the new instal picked it up.

Solution:
open the Xammpp Control Panel and click on the Services Button on the right. This will open the services control panel. Look for mysqld in the list of running processes, right-click it to get the properties and change the startup type to "Manual". you might as well do the same for Apache2 while you're here. Apply changes and Close the services control panel.

Now click the Config Button on xampp control panel, uncheck The Mysql (and Apache) Autostart features.

Reboot the machine. You should now be able to start / stop Mysql & Apache without any error messages. If this works, use the Xampp Control panel as usual to start/stop add service or add autostart as normal. No need to mess with any ports or config files.

why not just check if the value you want to check is equal to itself cast as an integer as shown below?

def isInt(val):
    return val == int(val)

Call this in the project:

svn diff -r REVNO:HEAD --summarize

REVNO is the start revision number and HEAD is the end revision number. If HEAD is equal to the last revision number, it can skip it.

The command returns a list with all files that are changed/added/deleted in this revision period.

The command can be called with the URL revision parameter to check changes like this:

svn diff -r REVNO:HEAD --summarize SVN_URL

I know it's a bit old but since I recently looked into it :

let l = UILabel()
l.numberOfLines = 0
l.lineBreakMode = .ByWordWrapping
l.text = "BLAH BLAH BLAH BLAH BLAH"
l.frame.size.width = 300
l.sizeToFit()

First set the numberOfLines property to 0 so that the device understands you don't care how many lines it needs. Then specify your favorite BreakMode Then the width needs to be set before sizeToFit() method. Then the label knows it must fit in the specified width

In my case the solution was:

Permissions on the config file should be 600. chmod 600 config

As mentioned in the comments above by generalopinion

No need to touch the config file contents.

JSON-RPC 2.0 defines a standard request and response format, and is a breath of fresh air after working with REST APIs.

If file name has no spaces:

ls -l <dir> | awk '{print $6, " ", $7, " ", $8, " ", $9 }'

This prints as the following format:

 Dec   21   20:03   a1.out
 Dec   21   20:04   a.cpp

If file names have space (you can use the following command for file names with no spaces too, just it looks complicated/ugly than the former):

 ls -l <dir> | awk '{printf ("%s %s %s ",  $6,  $7, $8); for (i=9;   i<=NF; i++){ printf ("%s ", $i)}; printf ("\n")}'

Every time you create an ajax request you could use a variable to store it:

var request = $.ajax({
    type: 'POST',
    url: 'someurl',
    success: function(result){}
});

Then you can abort the request:

request.abort();

You could use an array keeping track of all pending ajax requests and abort them if necessary.

You need to rename your main class to Main, it cannot be anything else.

It does not matter how many files as packages and classes you create, you must name your main class Main.

That's all.

The Instagram API is meant for not only you, but for any Instagram user to potentially authenticate with your app. I followed the instructions on the Instagram Dev website. Using the first (Explicit) method, I was able to do this quite easily on the server.

Step 1) Add a link or button to your webpage which a user could click to initiate the authentication process:

<a href="https://api.instagram.com/oauth/authorize/?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code">Get Started</a>

YOUR_CLIENT_ID and YOUR_REDIRECT_URI will be given to you after you successfully register your app in the Instagram backend, along with YOUR_CLIENT_SECRET used below.

Step 2) At the URI that you defined for your app, which is the same as YOUR_REDIRECT_URI, you need to accept the response from the Instagram server. The Instagram server will feed you back a code variable in the request. Then you need to use this code and other information about your app to make another request directly from your server to obtain the access_token. I did this in python using Django framework, as follows:

direct django to the response function in urls.py:

from django.conf.urls import url

from . import views

app_name = 'main'
urlpatterns = [
        url(r'^$', views.index, name='index'),
        url(r'^response/', views.response, name='response'),
]

Here is the response function, handling the request, views.py:

from django.shortcuts import render
import urllib
import urllib2
import json

def response(request):
    if 'code' in request.GET:
        url = 'https://api.instagram.com/oauth/access_token'
        values = {
            'client_id':'YOUR_CLIENT_ID',
            'client_secret':'YOUR_CLIENT_SECRET',
            'redirect_uri':'YOUR_REDIRECT_URI',
            'code':request.GET.get('code'),
            'grant_type':'authorization_code'
        }
        data = urllib.urlencode(values)
        req = urllib2.Request(url, data)
        response = urllib2.urlopen(req)
        response_string = response.read()
        insta_data = json.loads(response_string)
        if 'access_token' in insta_data and 'user' in insta_data:
            #authentication success
            return render(request, 'main/response.html')
        else:
            #authentication failure after step 2
            return render(request, 'main/auth_error.html')
    elif 'error' in req.GET:
        #authentication failure after step 1
        return render(request, 'main/auth_error.html')

This is just one way, but the process should be almost identical in PHP or any other server-side language.

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>

<form>
<select name="users" onchange="showUser(this.value)">
<option value="">Select a person:</option>
<option value="1">Peter Griffin</option>
<option value="2">Lois Griffin</option>
<option value="3">Glenn Quagmire</option>
<option value="4">Joseph Swanson</option>
</select>
</form>
<br />
<div id="txtHint"><b>Person info will be listed here.</b></div>

</body>
</html>

PHP code:

<?php
$q=$_GET["q"];

$con = mysql_connect('localhost', 'peter', 'abc123');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ajax_demo", $con);

$sql="SELECT * FROM user WHERE id = '".$q."'";

$result = mysql_query($sql);

echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
<th>Hometown</th>
<th>Job</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['FirstName'] . "</td>";
  echo "<td>" . $row['LastName'] . "</td>";
  echo "<td>" . $row['Age'] . "</td>";
  echo "<td>" . $row['Hometown'] . "</td>";
  echo "<td>" . $row['Job'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
?>

Typically you would always put the hyphen first in the [] match section. EG, to match any alphanumeric character including hyphens (written the long way), you would use [-a-zA-Z0-9]

<p style="text-indent: 5em;">
The first line of this paragraph will be indented about five characters, similar to a tabbed indent.
</p>

The first line of this paragraph will be indented about five characters, similar to a tabbed indent.

See How to Use HTML and CSS to Create Tabs and Spacing for more information.

You need to enable delayed expansion. Try this:

@echo off
setlocal enabledelayedexpansion
:blah
set /p input=:
echo."%input%"
for /f "tokens=* delims= " %%a in ("%input%") do set input=%%a
for /l %%a in (1,1,100) do if "!input:~-1!"==" " set input=!input:~0,-1!
echo."%input%"
pause
goto blah

I did it like this:

Model.findOne({
    where: {
      condtions
    }
  }).then( j => {
    return j.update({
      field you want to update
    }).then( r => {
      return res.status(200).json({msg: 'succesfully updated'});
    }).catch(e => {
      return res.status(400).json({msg: 'error ' +e});
    })
  }).catch( e => {
    return res.status(400).json({msg: 'error ' +e});
  });

This works for me even in IE9:

$('<img src="' + imgURL + '"/>').on('load', function(){ doOnLoadStuff(); });

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

I confirm that the audio isn't working as described (at least on iPad running 4.3.5). The specific issue is the audio won't load in an asynchronous method (ajax, timer event, etc) but it will play if it was preloaded. The problem is the load has to be on a user-triggered event. So if you can have a button for the user to initiate the playing you can do something like:

function initSounds() {
    window.sounds = new Object();
    var sound = new Audio('assets/sounds/clap.mp3');
    sound.load();
    window.sounds['clap.mp3'] = sound;
}

Then to play it, eg in an ajax request, you can do

function doSomething() {
    $.post('testReply.php',function(data){
        window.sounds['clap.mp3'].play();
    }); 
}

Not the greatest solution, but it may help, especially knowing the culprit is the load function in a non-user-triggered event.

Edit: I found Apple's explanation, and it affects iOS 4+: http://developer.apple.com/library/safari/#documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html

In my case I used below configuration at VM options in IntelliJ , it was not picking the local configurations but after a restart of IntelliJ it picked configuration details from IntelliJ and service started running.

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")

you forgot for Java Desktop Aplication based on JSR296 as built-in Swing Framework in NetBeans

excluding AWT and JavaFX are all of your desribed frameworks are based on Swing, if you'll start with Swing then you'd be understand (clearly) for all these Swing's (Based Frameworks)

ATW, SWT (Eclipse), Java Desktop Aplication(Netbeans), SwingX, JGoodies

all there frameworks (I don't know something more about JGoodies) incl. JavaFX haven't long time any progress, lots of Swing's Based Frameworks are stoped, if not then without newest version

just my view - best of them is SwingX, but required deepest knowledge about Swing,

Look and Feel for Swing's Based Frameworks

You can also use the <a> label with javascript: void(0) as href value.

Example as follow:
<a href="javascript: void(0)">+44 456 77 89 87</a>

Programs written in other languages (e.g. C) have to do special magic (called double-forking) expressly to detach from the terminal (and to prevent zombie processes). So, I think the best solution is to emulate them.

A plus of re-executing your program is, you can choose redirections on the command-line, e.g. /usr/bin/python mycoolscript.py 2>&1 1>/dev/null

sc.next().charat(0).........is the method of entering character by user based on the number entered at the run time

example: sc.next().charat(2)------------>>>>>>>>

firstly you need to import the Select class and then you need to create the instance of Select class. After creating the instance of Select class, you can perform select methods on that instance to select the options from dropdown list. Here is the code

from selenium.webdriver.support.select import Select

select_fr = Select(driver.find_element_by_id("fruits01"))
select_fr.select_by_index(0)

Little late to the party, but you can also do this:

<div style="height: 500px; width: 500px;">

<div class="bottom" style="height: 250px; width: 500px; background: red; margin-top: 250px;"></div>

<div class="top" style="height: 250px; width: 500px; background: blue; margin-top: -500px;"></div>

I am using Ubuntu 11.10- 32 bit with ruby 1.9.3p194, rails 3.2.3, gem 1.8.24. Was receiving the same Javascript error while running "script/rails console".

However doing a "sudo apt-get install nodejs" solved my issue.

tl;dr

Instant.now()
       .toString() 

2018-02-02T00:28:02.487114Z

Instant.parse(
    "2018-02-02T00:28:02.487114Z"
)

java.time

The accepted Answer by ppeterka is correct. Your abuse of the formatting pattern results in an erroneous display of data, while the internal value is always limited milliseconds.

The troublesome SimpleDateFormat and Date classes you are using are now legacy, supplanted by the java.time classes. The java.time classes handle nanoseconds resolution, much finer than the milliseconds limit of the legacy classes.

The equivalent to java.util.Date is java.time.Instant. You can even convert between them using new methods added to the old classes.

Instant instant = myJavaUtilDate.toInstant() ;

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Capture the current moment in UTC. Java 8 captures the current moment in milliseconds, while a new Clock implementation in Java 9 captures the moment in finer granularity, typically microseconds though it depends on the capabilities of your computer hardware clock & OS & JVM implementation.

Instant instant = Instant.now() ;

Generate a String in standard ISO 8601 format.

String output = instant.toString() ;

2018-02-02T00:28:02.487114Z

To generate strings in other formats, search Stack Overflow for DateTimeFormatter, already covered many times.

To adjust into a time zone other than UTC, use ZonedDateTime.

ZonedDateTime zdt = instant.atZone( ZoneId.of( "Pacific/Auckland" ) ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

To list the patches using sql :

select * from registry$history;

You can use JSON.stringify(your object, null, 2) The second parameter can be used as a replacer function which takes key and Val as parameters.This can be used in case you want to modify something within your JSON object.

I'd suggest looking into fetch. It is the ES5 equivalent and uses Promises. It is much more readable and easily customizable.

const url = "https://stackoverflow.com";
fetch(url)
    .then(
        response => response.text() // .json(), etc.
        // same as function(response) {return response.text();}
    ).then(
        html => console.log(html)
    );

In Node.js, you'll need to import fetch using:

const fetch = require("node-fetch");

If you want to use it synchronously (doesn't work in top scope):

const json = await fetch(url)
  .then(response => response.json())
  .catch((e) => {});

My solution is to use Process.GetProcess() for listing all the processes.

By filtering them to contain the processes I want, I can then run Process.Kill() method to stop them:

var chromeDriverProcesses = Process.GetProcesses().
    Where(pr => pr.ProcessName == "chromedriver"); // without '.exe'
    
foreach (var process in chromeDriverProcesses)
{
     process.Kill();
}

Update:

In case if want to use async approach with some useful recent methods from the C# 8 (Async Enumerables), then check this out:

const string processName = "chromedriver"; // without '.exe'
await Process.GetProcesses()
             .Where(pr => pr.ProcessName == processName)
             .ToAsyncEnumerable()
             .ForEachAsync(p => p.Kill());

Note: using async methods doesn't always mean code will run faster, but it will not waste the CPU time and prevent the foreground thread from hanging while doing the operations. In any case, you need to think about what version you might want.
