I notice a lot of people are recommending Convert.ChangeType - This does work for some cases however as soon as you start involving nullable types you will start receiving InvalidCastExceptions:

http://weblogs.asp.net/pjohnson/archive/2006/02/07/Convert.ChangeType-doesn_2700_t-handle-nullables.aspx

A wrapper was written a few years ago to handle this but that isn't perfect either.

http://weblogs.asp.net/pjohnson/archive/2006/02/07/Convert.ChangeType-doesn_2700_t-handle-nullables.aspx

While the above most upvoted answers definitely work, I'd suggest using a slightly different approach in some cases.

If your class has multiple properties with always the same attribute and you want to get those attributes sorted into a dictionary, here is how:

var dict = typeof(Book).GetProperties().ToDictionary(p => p.Name, p => p.GetCustomAttributes(typeof(AuthorName), false).Select(a => (AuthorName)a).FirstOrDefault());

This still uses cast but ensures that the cast will always work as you will only get the custom attributes of the type "AuthorName". If you had multiple Attributes above answers would get a cast exception.

If you code in Android, there is SparseArray, mapping integer to object.

Yes it s working: remove the path of jdk 9.0 and uninstall this from Cantroll panel instead install jdk 8version and set it's path, it is working easily with netbean 8.2.

In brief

• Xcode 3 introduced subproject, which is parent-child relationship, meaning that parent can reference its child target, but no vice versa
• Xcode 4 introduced workspace, which is sibling relationship, meaning that any project can reference projects in the same workspace

If the object element you get is a function, you can try this:

var url = myArray[i]();

Let's get you started. Do you have any knowledge in Oracle?

First you need to understand what a SCHEMA is. A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema. Schema objects can be created and manipulated with SQL.

1. CREATE USER acoder; -- whenever you create a new user in Oracle, a schema with the same name as the username is created where all his objects are stored.
2. GRANT CREATE SESSION TO acoder; -- Failure to do this you cannot do anything.

To access another user's schema, you need to be granted privileges on specific object on that schema or optionally have SYSDBA role assigned.

That should get you started.

First get the value from edit text in a String variable

String value = edttxt.getText().toString();

Then set that value to textView

txtview.setText(value);

Where edttxt refers to edit text field in XML file and txtview refers to textfield in XML file to show the value

Here is another method to add days on date using dateutil's relativedelta.

from datetime import datetime
from dateutil.relativedelta import relativedelta

print 'Today: ',datetime.now().strftime('%d/%m/%Y %H:%M:%S') 
date_after_month = datetime.now()+ relativedelta(day=1)
print 'After a Days:', date_after_month.strftime('%d/%m/%Y %H:%M:%S')

Output:

Today: 25/06/2015 20:41:44

After a Days: 01/06/2015 20:41:44

You need to set the correct content type and stringify your object.

var arr = {City:'Moscow', Age:25};
$.ajax({
    url: "Ajax.ashx",
    type: "POST",
    data: JSON.stringify(arr),
    dataType: 'json',
    async: false,
    contentType: 'application/json; charset=utf-8',
    success: function(msg) {
        alert(msg);
    }
});

Pika is a CDN that takes care of providing module versions of popular packages

<script type='module'>
    import * as $ from 'https://cdn.skypack.dev/jquery';

    // use it!
    $('#myDev').on('click', alert);
</script>

Skypack is Pika, so you could also use: import * as $ from 'https://cdn.pika.dev/jquery@^3.5.1';

Simple solution, not much smart:

Temporarily block a part of a script:

if false; then
    while you respect syntax a bit, please
    do write here (almost) whatever you want.
    but when you are
    done # write
fi

A bit sophisticated version:

time_of_debug=false # Let's set this variable at the beginning of a script

if $time_of_debug; then # in a middle of the script  
    echo I keep this code aside until there is the time of debug!
fi

I didn't try this but I think it works in all browsers:

target="_parent"

I need to do this from time to time and end up hacking the command line until it works.

For example, here I want to see if I have any SSH connections, (the 8th column returned by "ps" is the running "path-to-procname" and is filtered by "awk":

ps | awk -e '{ print $8 }' | grep ssh | sed -e 's/.*\///g'

Then I put it in a shell-script, ("eval"-ing the command line inside of backticks), like this:

#!/bin/bash

VNC_STRING=`ps | awk -e '{ print $8 }' | grep vnc | sed -e 's/.*\///g'`

if [ ! -z "$VNC_STRING" ]; then
    echo "The VNC STRING is not empty, therefore your process is running."
fi

The "sed" part trims the path to the exact token and might not be necessary for your needs.

Here's my example I used to get your answer. I wrote it to automatically create 2 SSH tunnels and launch a VNC client for each.

I run it from my Cygwin shell to do admin to my backend from my windows workstation, so I can jump to UNIX/LINUX-land with one command, (this also assumes the client rsa keys have already been "ssh-copy-id"-ed and are known to the remote host).

It's idempotent in that each proc/command only fires when their $VAR eval's to an empty string.

It appends " | wc -l" to store the number of running procs that match, (i.e., number of lines found), instead of proc-name for each $VAR to suit my needs. I keep the "echo" statements so I can re-run and diagnose the state of both connections.

#!/bin/bash

SSH_COUNT=`eval ps | awk -e '{ print $8 }' | grep ssh | sed -e 's/.*\///g' | wc -l`
VNC_COUNT=`eval ps | awk -e '{ print $8 }' | grep vnc | sed -e 's/.*\///g' | wc -l`

if  [ $SSH_COUNT = "2" ]; then
    echo "There are already 2 SSH tunnels."
elif  [ $SSH_COUNT = "1" ]; then
    echo "There is only 1 SSH tunnel."
elif [ $SSH_COUNT = "0" ]; then
    echo "connecting 2 SSH tunnels."
    ssh -L 5901:localhost:5901 -f -l USER1 HOST1 sleep 10;
    ssh -L 5904:localhost:5904 -f -l USER2 HOST2 sleep 10;
fi

if  [ $VNC_COUNT = "2" ]; then
    echo "There are already 2 VNC sessions."
elif  [ $VNC_COUNT = "1" ]; then
    echo "There is only 1 VNC session."
elif [ $VNC_COUNT = "0" ]; then
    echo "launching 2 vnc sessions."
    vncviewer.exe localhost:1 &
    vncviewer.exe localhost:4 &
fi

This is very perl-like to me and possibly more unix utils than true shell scripting. I know there are lots of "MAGIC" numbers and cheezy hard-coded values but it works, (I think I'm also in poor taste for using so much UPPERCASE too). Flexibility can be added with some cmd-line args to make this more versatile but I wanted to share what worked for me. Please improve and share. Cheers.

Say you have array named list. The Splice() function can be used for both adding and removing item in that array in specific index i.e that can be in the beginning or in the end or at any index. On the contrary there are another function name shift() and pop() which is capable of removing only the first and last item in the array.

This is the Shift Function which is only capable of removing the first element of the array

var item = [ 1,1,2,3,5,8,13,21,34 ]; // say you have this number series 
item.shift(); // [ 1,2,3,5,8,13,21,34 ];

The Pop Function removes item from an array at its last index

item.pop(); // [ 1,2,3,5,8,13,21 ];

Now comes the splice function by which you can remove item at any index

item.slice(0,1); // [ 2,3,5,8,13,21 ] removes the first object
item.slice(item.length-1,1); // [ 2,3,5,8,13 ] removes the last object 

The slice function accepts two parameters (Index to start with, number of steps to go);

If you want to know what properties (and methods) there are:

Get-WmiObject -Class "Win32_computersystem" | Get-Member

It is related to generics in java. If I mentioned ArrayList<String> that means I can add only String type object to that ArrayList.

The two major benefits of generics in Java are:

1. Reducing the number of casts in your program, thus reducing the number of potential bugs in your program.
2. Improving code clarity

Wikipedia has us covered:

In computer science, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to attain a particular goal. It is a special case of engineering overhead.

Using straight Linq, with the Distinct() extension:

var idList = (from x in yourList select x.ID).Distinct();

You need to add logic to assign random values to double[] array using randomFill method.

Change

 public static double[] list(){
    anArray = new double[10];   
    return anArray;
 }

To

 public static double[] list() {
    anArray = new double[10];
    for(int i=0;i<anArray.length;i++)
    {
        anArray[i] = randomFill();
    }
    return anArray;
}

Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console.

 public static void main(String args[]) {

list();
print();
 }

One result is as follows:

-2.89783865E8 
1.605018025E9

Use imageWithData: method, which gets translated to Swift as UIImage(data:)

let image : UIImage = UIImage(data: imageData)

I think this could help..

[[AFNetworkReachabilityManager sharedManager] startMonitoring];

if([AFNetworkReachabilityManager sharedManager].isReachable)
{
    NSLog(@"Network reachable");
}
else
{   
   NSLog(@"Network not reachable");
}

Stashing, temporary commits and rebasing may all be overkill. If you haven't added the changed files to the index, yet, then you may be able to just checkout the other branch.

git checkout branch2

This will work so long as no files that you are editing are different between branch1 and branch2. It will leave you on branch2 with you working changes preserved. If they are different then you can specify that you want to merge your local changes with the changes introduced by switching branches with the -m option to checkout.

git checkout -m branch2

If you've added changes to the index then you'll want to undo these changes with a reset first. (This will preserve your working copy, it will just remove the staged changes.)

git reset

As an alternative to copying the data you can make a wrapper that gives you access to a part of the original array as if it was a copy of the part of the array. The advantage is that you don't get another copy of the data in memory, and the drawback is a slight overhead when accessing the data.

public class SubArray<T> : IEnumerable<T> {

   private T[] _original;
   private int _start;

   public SubArray(T[] original, int start, int len) {
      _original = original;
      _start = start;
      Length = len;
   }

   public T this[int index] {
      get {
         if (index < 0 || index >= Length) throw new IndexOutOfRangeException();
         return _original[_start + index];
      }
   }

   public int Length { get; private set; }

   public IEnumerator<T> GetEnumerator() {
      for (int i = 0; i < Length; i++) {
        yield return _original[_start + i];
      }
   }

   IEnumerator IEnumerable.GetEnumerator() {
      return GetEnumerator();
   }

}

Usage:

int[] original = { 1, 2, 3, 4, 5 };
SubArray<int> copy = new SubArray<int>(original, 2, 2);

Console.WriteLine(copy.Length); // shows: 2
Console.WriteLine(copy[0]); // shows: 3
foreach (int i in copy) Console.WriteLine(i); // shows 3 and 4

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). The default bundle is named curl-ca-bundle.crt; you can specify an alternate file using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

for example

curl --insecure http://........

The real problem of why you are getting the error is not that there is anything wrong with your code: you can use either iloc, loc, or apply, or *=, another of them could have worked.

The real problem that you have is due to how you created the df DataFrame. Most likely you created your df as a slice of another DataFrame without using .copy(). The correct way to create your df as a slice of another DataFrame is df = original_df.loc[some slicing].copy().

The problem is already stated in the error message you got " SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead"
You will get the same message in the most current version of pandas too.

Whenever you receive this kind of error message, you should always check how you created your DataFrame. Chances are you forgot the .copy()

Interface means a class that has no implementation of its method, but with just declaration.
Other hand, abstract class is a class that can have implementation of some method along with some method with just declaration, no implementation.
When we implement an interface to an abstract class, its means that the abstract class inherited all the methods of the interface. As, it is not important to implement all the method in abstract class however it comes to abstract class (by inheritance too), so the abstract class can left some of the method in interface without implementation here. But, when this abstract class will inherited by some concrete class, they must have to implements all those unimplemented method there in abstract class.

IIRC, the ConfigurationManager.RefreshSection requires a string parameter specifying the name of the Section to refresh :

ConfigurationManager.RefreshSection("connectionStrings");

I think that the ASP.NET application should automatically reload when the ConnectionStrings element is modified and the configuration does not need to be manually reloaded.

A simple answer is to use @Html.TextboxFor but place it in a div that is hidden with style. Example: In View:

<div style="display:none"> @Html.TextboxFor(x=>x.CRN) </div>

To @R.. I think it's not enough to check errno for error detection in strtol call.

long strtol (const char *String, char **EndPointer, int Base)

You'll also need to check EndPointer for errors.

Alternatively, if you just want to convert one particular row to uppercase, use the code below:

df[[1]] <- toupper(df[[1]])

Also, there's the handy little "increase indent" and "decrease indent" buttons. If you highlight a block of code and click those buttons the entire block will indent.

In my case the sub domain name causes the problem. Here are details

I used app_development.something.com, here underscore(_) sub domain is creating CORS error. After changing app_development to app-development it works fine.

I ran into this error while trying to click some element (or its overlay, I didn't care), and the other answers didn't work for me. I fixed it by using the elementFromPoint DOM API to find the element that Selenium wanted me to click on instead:

element_i_care_about = something()
loc = element_i_care_about.location
element_to_click = driver.execute_script(
    "return document.elementFromPoint(arguments[0], arguments[1]);",
    loc['x'],
    loc['y'])
element_to_click.click()

I've also had situations where an element was moving, for example because an element above it on the page was doing an animated expand or collapse. In that case, this Expected Condition class helped. You give it the elements that are animated, not the ones you want to click. This version only works for jQuery animations.

class elements_not_to_be_animated(object):
    def __init__(self, locator):
        self.locator = locator

    def __call__(self, driver):
        try:
            elements = EC._find_elements(driver, self.locator)
            # :animated is an artificial jQuery selector for things that are
            # currently animated by jQuery.
            return driver.execute_script(
                'return !jQuery(arguments[0]).filter(":animated").length;',
                elements)
        except StaleElementReferenceException:
            return False

This will work for general reading a String from Text. If you would like to read longer text (large size of text), then use the method that other people here were mentioned such as buffered (reserve the size of the text in memory space).

Say you read a Text File.

NSString* filePath = @""//file path...
NSString* fileRoot = [[NSBundle mainBundle] 
               pathForResource:filePath ofType:@"txt"];

You want to get rid of new line.

// read everything from text
NSString* fileContents = 
      [NSString stringWithContentsOfFile:fileRoot 
       encoding:NSUTF8StringEncoding error:nil];

// first, separate by new line
NSArray* allLinedStrings = 
      [fileContents componentsSeparatedByCharactersInSet:
      [NSCharacterSet newlineCharacterSet]];

// then break down even further 
NSString* strsInOneLine = 
      [allLinedStrings objectAtIndex:0];

// choose whatever input identity you have decided. in this case ;
NSArray* singleStrs = 
      [currentPointString componentsSeparatedByCharactersInSet:
      [NSCharacterSet characterSetWithCharactersInString:@";"]];

There you have it.

I had the same problem and I found this is working:

if ($("#deliveryNext").attr('disabled')) {
  // do sth if disabled
} else {
  // do sth if enabled 
}

If this gives you undefined then you can use if condition also.

When you evaluate undefined it will return false.

You can use matplotlib to plot the histogram and the PDF (as in the link in @MrE's answer). For fitting and for computing the PDF, you can use scipy.stats.norm, as follows.

import numpy as np
from scipy.stats import norm
import matplotlib.pyplot as plt


# Generate some data for this demonstration.
data = norm.rvs(10.0, 2.5, size=500)

# Fit a normal distribution to the data:
mu, std = norm.fit(data)

# Plot the histogram.
plt.hist(data, bins=25, density=True, alpha=0.6, color='g')

# Plot the PDF.
xmin, xmax = plt.xlim()
x = np.linspace(xmin, xmax, 100)
p = norm.pdf(x, mu, std)
plt.plot(x, p, 'k', linewidth=2)
title = "Fit results: mu = %.2f,  std = %.2f" % (mu, std)
plt.title(title)

plt.show()

Here's the plot generated by the script:

In my case, I was getting this error message only in Production but not when run locally, even though my application's binaries were identical.

In my application, I'm using a custom DbModelStore so that the runtime-generated EDMX is saved to disk and loaded from disk on startup (instead of regenerating it from scratch) to reduce application startup time - and due to a bug in my code I wasn't invalidating the EDMX file on-disk - so Production was using an older version of the EDMX file from disk that referenced an older version of my application's types from before I renamed the type-name in the exception error message.

Deleting the cache file and restarting the application fixed it.

you need to add it like

insert into table1(date1) values('12-mar-2013');

If no other process is using the port 8080, Eventhough eclipse shows the port 8080 is used while starting the server in eclipse, first you have to stop the server by hitting the stop button in "Configure Tomcat"(which you can find in your start menu under tomcat folder), then try to start the server in eclipse then it will be started.

If any other process is using the port 8080 and as well as you no need to disturb it. then you can change the port.

Use @media queries. They serve this exact purpose. Here's an example how they work:

@media (max-width: 800px) {
  /* CSS that should be displayed if width is equal to or less than 800px goes here */
}

This would work only on devices whose width is equal to or less than 800px.

Read up more about media queries on the Mozilla Developer Network.

What you have seems to be a string incorrectly decoded from another encoding, likely code page 1252, which is US Windows default. Here's how to reverse, assuming no other loss. One loss not immediately apparent is the non-breaking space (U+00A0) at the end of your string that is not displayed. Of course it would be better to read the data source correctly in the first place, but perhaps the data source was stored incorrectly to begin with.

using System;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        string junk = "déjÃ\xa0";  // Bad Unicode string

        // Turn string back to bytes using the original, incorrect encoding.
        byte[] bytes = Encoding.GetEncoding(1252).GetBytes(junk);

        // Use the correct encoding this time to convert back to a string.
        string good = Encoding.UTF8.GetString(bytes);
        Console.WriteLine(good);
    }
}

Result:

déjà

run npm config set python python2.7 and run npm install again the party is on.

To embed this in your script, you can do it like this:

        Write-Output $server.name | Out-File '(Your Path)\Servers.txt' -Append

That should do the trick.

Your problem is that you load an external image, meaning from another domain. This causes a security error when you try to access any data of your canvas context.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

You cannot, due to security reasons.

Imagine:

<form name="foo" method="post" enctype="multipart/form-data">
    <input type="file" value="c:/passwords.txt">
</form>
<script>document.foo.submit();</script>

You don't want the websites you visit to be able to do this, do you? =)

Below working for me

display: block;
width: 100%;

I can think of doing it in two ways:

1.

Storing the file in file system in any directory (say dir1) and renaming it which ensures that the name is unique for every file (may be a timestamp) (say xyz123.jpg), and then storing this name in some DataBase. Then while generating the JSON you pull this filename and generate a complete URL (which will be http://example.com/dir1/xyz123.png )and insert it in the JSON.

2.

Base 64 Encoding, It's basically a way of encoding arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end. Essentially each 6 bits of the input is encoded in a 64-character alphabet. The "standard" alphabet uses A-Z, a-z, 0-9 and + and /, with = as a padding character. There are URL-safe variants. So this approach will allow you to put your image directly in the MongoDB, while storing it Encode the image and decode while fetching it, it has some of its own drawbacks:

• base64 encoding makes file sizes roughly 33% larger than their original binary representations, which means more data down the wire (this might be exceptionally painful on mobile networks)
• data URIs aren’t supported on IE6 or IE7.
• base64 encoded data may possibly take longer to process than binary data.

Converting Image to DATA URI

A.) Canvas

Load the image into an Image-Object, paint it to a canvas and convert the canvas back to a dataURL.

function convertToDataURLviaCanvas(url, callback, outputFormat){
    var img = new Image();
    img.crossOrigin = 'Anonymous';
    img.onload = function(){
        var canvas = document.createElement('CANVAS');
        var ctx = canvas.getContext('2d');
        var dataURL;
        canvas.height = this.height;
        canvas.width = this.width;
        ctx.drawImage(this, 0, 0);
        dataURL = canvas.toDataURL(outputFormat);
        callback(dataURL);
        canvas = null; 
    };
    img.src = url;
}

Usage

convertToDataURLviaCanvas('http://bit.ly/18g0VNp', function(base64Img){
    // Base64DataURL
});

B.) FileReader

Load the image as blob via XMLHttpRequest and use the FileReader API to convert it to a data URL.

function convertFileToBase64viaFileReader(url, callback){
    var xhr = new XMLHttpRequest();
    xhr.responseType = 'blob';
    xhr.onload = function() {
      var reader  = new FileReader();
      reader.onloadend = function () {
          callback(reader.result);
      }
      reader.readAsDataURL(xhr.response);
    };
    xhr.open('GET', url);
    xhr.send();
}

This approach

• lacks in browser support
• has better compression
• works for other file types as well.

Usage

convertFileToBase64viaFileReader('http://bit.ly/18g0VNp', function(base64Img){
    // Base64DataURL
});

Source

This worked for me:

byte[] bfoo = (byte[])foo;

foo is an Object that I'm 100% certain that is a byte array.

Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.

In your class, do something like this:

public void setSqlResource(Resource sqlResource) {
    this.sqlResource = sqlResource;
}

And then in your application context file, in the bean definition, just set a property:

<bean id="someBean" class="...">
    <property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>

And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.

You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.

The code you have is correct. JSX code needs to be compiled to JS:

http://facebook.github.io/react/jsx-compiler.html

Workaround:

 tableView.getColumns().get(0).setVisible(false);
 tableView.getColumns().get(0).setVisible(true);

Select Case parameter 
    ' does something here. 
    ' does something here. 
    Case "userID", "packageID", "mvrType" 
        If otherFactor Then 
            ' does something here. 
        Else 
            goto case default 
        End If 
    Case Else 
        ' does some processing... 
        Exit Select 
End Select

The listFiles method, with or without a filter does not guarantee any order.

It does, however, return an array, which you can sort with Arrays.sort().

File[] files = XMLDirectory.listFiles(filter_xml_files);
Arrays.sort(files);
for(File _xml_file : files) {
    ...
}

This works because File is a comparable class, which by default sorts pathnames lexicographically. If you want to sort them differently, you can define your own comparator.

If you prefer using Streams:

A more modern approach is the following. To print the names of all files in a given directory, in alphabetical order, do:

Files.list(Paths.get(dirName)).sorted().forEach(System.out::println)

Replace the System.out::println with whatever you want to do with the file names. If you want only filenames that end with "xml" just do:

Files.list(Paths.get(dirName))
    .filter(s -> s.toString().endsWith(".xml"))
    .sorted()
    .forEach(System.out::println)

Again, replace the printing with whichever processing operation you would like.

Most layout managers work best with a component's preferredSize, and most GUI's are best off allowing the components they contain to set their own preferredSizes based on their content or properties. To use these layout managers to their best advantage, do call pack() on your top level containers such as your JFrames before making them visible as this will tell these managers to do their actions -- to layout their components.

Often when I've needed to play a more direct role in setting the size of one of my components, I'll override getPreferredSize and have it return a Dimension that is larger than the super.preferredSize (or if not then it returns the super's value).

For example, here's a small drag-a-rectangle app that I created for another question on this site:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MoveRect extends JPanel {
   private static final int RECT_W = 90;
   private static final int RECT_H = 70;
   private static final int PREF_W = 600;
   private static final int PREF_H = 300;
   private static final Color DRAW_RECT_COLOR = Color.black;
   private static final Color DRAG_RECT_COLOR = new Color(180, 200, 255);
   private Rectangle rect = new Rectangle(25, 25, RECT_W, RECT_H);
   private boolean dragging = false;
   private int deltaX = 0;
   private int deltaY = 0;

   public MoveRect() {
      MyMouseAdapter myMouseAdapter = new MyMouseAdapter();
      addMouseListener(myMouseAdapter);
      addMouseMotionListener(myMouseAdapter);
   }

   @Override
   protected void paintComponent(Graphics g) {
      super.paintComponent(g);
      if (rect != null) {
         Color c = dragging ? DRAG_RECT_COLOR : DRAW_RECT_COLOR;
         g.setColor(c);
         Graphics2D g2 = (Graphics2D) g;
         g2.draw(rect);
      }
   }

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

   private class MyMouseAdapter extends MouseAdapter {

      @Override
      public void mousePressed(MouseEvent e) {
         Point mousePoint = e.getPoint();
         if (rect.contains(mousePoint)) {
            dragging = true;
            deltaX = rect.x - mousePoint.x;
            deltaY = rect.y - mousePoint.y;
         }
      }

      @Override
      public void mouseReleased(MouseEvent e) {
         dragging = false;
         repaint();
      }

      @Override
      public void mouseDragged(MouseEvent e) {
         Point p2 = e.getPoint();
         if (dragging) {
            int x = p2.x + deltaX;
            int y = p2.y + deltaY;
            rect = new Rectangle(x, y, RECT_W, RECT_H);
            MoveRect.this.repaint();
         }
      }
   }

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

Note that my main class is a JPanel, and that I override JPanel's getPreferredSize:

public class MoveRect extends JPanel {
   //.... deleted constants

   private static final int PREF_W = 600;
   private static final int PREF_H = 300;

   //.... deleted fields and constants

   //... deleted methods and constructors

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

Also note that when I display my GUI, I place it into a JFrame, call pack(); on the JFrame, set its position, and then call setVisible(true); on my JFrame:

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

Another way to create an array with String apart from

String[] strings =  { "abc", "def", "hij", "xyz" };

is to use split. I find this more readable if there are lots of Strings.

String[] strings =  "abc,def,hij,xyz".split(",");

or the following is good if you are parsing lines of strings from another source.

String[] strings =  ("abc\n" +
                     "def\n" +
                     "hij\n" +
                     "xyz").split("\n");

It happens that I'm just starting to learn coding and I needed something similar as you have just asked in SQLite (I´m using [SQLiteStudio] (3.1.1)).

It happens that you must define the column's 'Constraint' as 'Not Null' then entering your desired definition using 'Default' 'Constraint' or it will not work (I don't know if this is an SQLite or the program requirment).

Here is the code I used:

CREATE TABLE <MY_TABLE> (
<MY_TABLE_KEY>       INTEGER    UNIQUE
                                PRIMARY KEY,
<MY_TABLE_SERIAL>    TEXT       DEFAULT (<MY_VALUE>) 
                                NOT NULL
<THE_REST_COLUMNS>
);

for (Iterator<String> itr = someList.iterator(); itr.hasNext(); ) {
   String item = itr.next();
   System.out.println(item);
}

Update for Java 8 and higher

You can now simply do Instant.parse("2015-04-28T14:23:38.521Z") and get the correct thing now, especially since you should be using Instant instead of the broken java.util.Date with the most recent versions of Java.

You should be using DateTimeFormatter instead of SimpleDateFormatter as well.

Original Answer:

The explanation below is still valid as as what the format represents. But it was written before Java 8 was ubiquitous so it uses the old classes that you should not be using if you are using Java 8 or higher.

This works with the input with the trailing Z as demonstrated:

In the pattern the T is escaped with ' on either side.

The pattern for the Z at the end is actually XXX as documented in the JavaDoc for SimpleDateFormat, it is just not very clear on actually how to use it since Z is the marker for the old TimeZone information as well.

Convert nodes Array to Tree

ES6 function to convert an Array of nodes (related by parent ID) - to a Tree structure:

/**
 * Convert nodes list related by parent ID - to tree.
 * @syntax getTree(nodesArray [, rootID [, propertyName]])
 *
 * @param {Array} arr   Array of nodes
 * @param {integer} id  Defaults to 0
 * @param {string} p    Property name. Defaults to "parent_id"
 * @returns {Object}    Nodes tree
 */

const getTree = (arr, p = "parent_id") => arr.reduce((o, n) => {

  if (!o[n.id]) o[n.id] = {};
  if (!o[n[p]]) o[n[p]] = {};
  if (!o[n[p]].nodes) o[n[p]].nodes= [];
  if (o[n.id].nodes) n.nodes= o[n.id].nodes;

  o[n[p]].nodes.push(n);
  o[n.id] = n;

  return o;
}, {});

Generate HTML List from nodes Tree

Having our Tree in place, here's a recursive function to build the UL > LI Elements:

/**
 * Convert Tree structure to UL>LI and append to Element
 * @syntax getTree(treeArray [, TargetElement [, onLICreatedCallback ]])
 *
 * @param {Array} tree Tree array of nodes
 * @param {Element} el HTMLElement to insert into
 * @param {function} cb Callback function called on every LI creation
 */

const treeToHTML = (tree, el, cb) => el.append(tree.reduce((ul, n) => {
  const li = document.createElement('li');

  if (cb) cb.call(li, n);
  if (n.nodes?.length) treeToHTML(n.nodes, li, cb);

  ul.append(li);
  return ul;
}, document.createElement('ul')));

If non of above works for you, make sure tomcat has access to manager folder under webapps (chown ...). The message is the exact same message, and It took me 2 hours to figure out the problem. :-)

just for someone else who came here for the same issue as me.

@JsonSerialize and @JsonDeserialize worked fine for me. They eliminate the need to import the additional jsr310 module:

@JsonDeserialize(using = LocalDateDeserializer.class)  
@JsonSerialize(using = LocalDateSerializer.class)  
private LocalDate dateOfBirth;

Deserializer:

public class LocalDateDeserializer extends StdDeserializer<LocalDate> {

    private static final long serialVersionUID = 1L;

    protected LocalDateDeserializer() {
        super(LocalDate.class);
    }


    @Override
    public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt)
            throws IOException, JsonProcessingException {
        return LocalDate.parse(jp.readValueAs(String.class));
    }

}

Serializer:

public class LocalDateSerializer extends StdSerializer<LocalDate> {

    private static final long serialVersionUID = 1L;

    public LocalDateSerializer(){
        super(LocalDate.class);
    }

    @Override
    public void serialize(LocalDate value, JsonGenerator gen, SerializerProvider sp) throws IOException, JsonProcessingException {
        gen.writeString(value.format(DateTimeFormatter.ISO_LOCAL_DATE));
    }
}

Could anybody post a working solution for doing this in the terminal?

ANDROID_HOME is usually a directory like .android. Its where things like the Debug Key will be stored.

export ANDROID_HOME=~/.android 

You can automate it for your login. Just add it to your .bash_profile (below is from my OS X 10.8.5 machine):

$ cat ~/.bash_profile
# MacPorts Installer addition on 2012-07-19 at 20:21:05
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

# Android
export ANDROID_NDK_ROOT=/opt/android-ndk-r9
export ANDROID_SDK_ROOT=/opt/android-sdk
export JAVA_HOME=`/usr/libexec/java_home`
export ANDROID_HOME=~/.android

export PATH="$ANDROID_SDK_ROOT/tools/":"$ANDROID_SDK_ROOT/platform-tools/":"$PATH"

According to David Turner on the NDK Mailing List, both ANDROID_NDK_ROOT and ANDROID_SDK_ROOT need to be set because other tools depend on those values (see Recommended NDK Directory?).

After modifying ~/.bash_profile, then perform the following (or logoff and back on):

source ~/.bash_profile

WHERE dates BETWEEN (convert(datetime, '2012-12-12',110) AND (convert(datetime, '2012-12-12',110))

You could pass the messages as explicit URL parameter (appropriately encoded), or store the messages into session (cookie) variable before redirecting and then get the variable before rendering the template. For example:

from flask import session, url_for

def do_baz():
    messages = json.dumps({"main":"Condition failed on page baz"})
    session['messages'] = messages
    return redirect(url_for('.do_foo', messages=messages))

@app.route('/foo')
def do_foo():
    messages = request.args['messages']  # counterpart for url_for()
    messages = session['messages']       # counterpart for session
    return render_template("foo.html", messages=json.loads(messages))

(encoding the session variable might not be necessary, flask may be handling it for you, but can't recall the details)

Or you could probably just use Flask Message Flashing if you just need to show simple messages.

For Those who want to validate an Enum in their code you can following the guide

In Regex World you can use ^ for starting a string and $ to end it. Using them in combination with | could be what you want :

^(Male)$|^(Female)$

It will return true only for Male or Female case.

Beginning with Java 7, you can use the following idiom:

String someString = "...";
InputStream is = new ByteArrayInputStream( someString.getBytes(StandardCharsets.UTF_8) );

One possible way to work around requests is using the library betamax, it records all requests and after that if you make a request in the same url with the same parameters the betamax will use the recorded request, I have been using it to test web crawler and it save me a lot time.

import os

import requests
from betamax import Betamax
from betamax_serializers import pretty_json


WORKERS_DIR = os.path.dirname(os.path.abspath(__file__))
CASSETTES_DIR = os.path.join(WORKERS_DIR, u'resources', u'cassettes')
MATCH_REQUESTS_ON = [u'method', u'uri', u'path', u'query']

Betamax.register_serializer(pretty_json.PrettyJSONSerializer)
with Betamax.configure() as config:
    config.cassette_library_dir = CASSETTES_DIR
    config.default_cassette_options[u'serialize_with'] = u'prettyjson'
    config.default_cassette_options[u'match_requests_on'] = MATCH_REQUESTS_ON
    config.default_cassette_options[u'preserve_exact_body_bytes'] = True


class WorkerCertidaoTRT2:
    session = requests.session()

    def make_request(self, input_json):
        with Betamax(self.session) as vcr:
            vcr.use_cassette(u'google')
            response = session.get('http://www.google.com')

Close the cursor, if it is empty then deallocate it:

IF CURSOR_STATUS('global','myCursor') >= -1
 BEGIN
  IF CURSOR_STATUS('global','myCursor') > -1
   BEGIN
    CLOSE myCursor
   END
 DEALLOCATE myCursor
END

$_SESSION is your friend if you don't want to mess with Javascript

Let's say you're trying to pass an email:

On page A:

// Start the session
session_start();

// Set session variables
$_SESSION["email"] = "[email protected]";

header('Location: page_b.php');

And on Page B:

// Start the session
session_start();

// Show me the session!  
echo "<pre>";
print_r($_SESSION);
echo "</pre>";

To destroy the session

unset($_SESSION['email']);
session_destroy();

I've done it before, I just used:

down.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            return true;
        }
    });

Per documentation:

public void setOnLongClickListener (View.OnLongClickListener l)

Since: API Level 1 Register a callback to be invoked when this view is clicked and held. If this view is not long clickable, it becomes long clickable.

Notice that it requires to return a boolean, this should work.

When in Node.js or when using require.js in the browser, you can simply do:

let json = require('/Users/Documents/workspace/test.json');
console.log(json, 'the json obj');

Do note: the file is loaded once, subsequent calls will use the cache.

In c++ like this:

enum OS_type{Linux, Apple, Windows};

std::string ToString( const OS_type v )

Remove last 3 characters of a string

var str = '1437203995000';
str = str.substring(0, str.length-3);
// '1437203995'

Remove last 3 digits of a number

var a = 1437203995000;
a = (a-(a%1000))/1000;
// a = 1437203995

Here is a sample that will help in applying button style consistently across your app.

Here is a sample Theme I used with the specific styles..

<style name="MyTheme" parent="@style/Theme.AppCompat.Light">
   <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/primary_dark</item>
    <item name="colorAccent">@color/accent</item>
    <item name="android:buttonStyle">@style/ButtonAppTheme</item>
</style>
<style name="ButtonAppTheme" parent="android:Widget.Material.Button">
<item name="android:background">@drawable/material_button</item>
</style>

This is how I defined the button shape & effects inside res/drawable-v21 folder...

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?attr/colorControlHighlight">
  <item>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
      <corners android:radius="2dp" /> 
      <solid android:color="@color/primary" />
    </shape>
  </item>
</ripple>

2dp corners are to keep it consistent with Material theme.

OP's problem was related with HTML coding. But if you are using plain text, please use "\n" and not "\r\n".

My personal use case: using mailx mailer, simply replacing "\r\n" into "\n" fixed my issue, related with wrong automatic Content-Type setting.

Wrong header:

User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64

Correct header:

User-Agent: Heirloom mailx 12.4 7/29/08
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I'm not saying that "application/octet-stream" and "base64" are always wrong/unwanted, but they where in my case.

Just provide the jQuery val function with an array of values:

var values = "Test,Prof,Off";
$('#strings').val(values.split(','));

And to get the selected values in the same format:

values = $('#strings').val();

Try this:

> HISTTIMEFORMAT="%d/%m/%y %T "

> history

You can adjust the format to your liking, of course.

Syntax of waitpid():

pid_t waitpid(pid_t pid, int *status, int options);

The value of pid can be:

• < -1: Wait for any child process whose process group ID is equal to the absolute value of pid.
• -1: Wait for any child process.
• 0: Wait for any child process whose process group ID is equal to that of the calling process.
• > 0: Wait for the child whose process ID is equal to the value of pid.

The value of options is an OR of zero or more of the following constants:

• WNOHANG: Return immediately if no child has exited.
• WUNTRACED: Also return if a child has stopped. Status for traced children which have stopped is provided even if this option is not specified.
• WCONTINUED: Also return if a stopped child has been resumed by delivery of SIGCONT.

For more help, use man waitpid.

I'd recommend using ActiveRecord::Base.connection.exec_query instead of ActiveRecord::Base.connection.execute which returns a ActiveRecord::Result (available in rails 3.1+) which is a bit easier to work with.

Then you can access it in various the result in various ways like .rows, .each, or .to_hash

From the docs:

result = ActiveRecord::Base.connection.exec_query('SELECT id, title, body FROM posts')
result # => #<ActiveRecord::Result:0xdeadbeef>


# Get the column names of the result:
result.columns
# => ["id", "title", "body"]

# Get the record values of the result:
result.rows
# => [[1, "title_1", "body_1"],
      [2, "title_2", "body_2"],
      ...
     ]

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

# ActiveRecord::Result also includes Enumerable.
result.each do |row|
  puts row['title'] + " " + row['body']
end

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?

I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwd which has issues with OverlayFS. I found information about this here:

It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes (if you're actually building bash and your C library does malloc a getcwd call).

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

Passing it a few ws will ignore the display width.

I think this is what you want:

$friends = $facebook->api('/me/friends');

if you need a performance trick use below:

$(".yourclass", this);

find() method makes a search everytime in selector.

I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.

If you are using NASM, the command-line is just

nasm -felf32 -g -Fdwarf file.asm -o file.o

where 'file.asm' is your assembly file (code) and 'file.o' is an object file you can link with gcc -m32 or ld -melf_i386. (Assembling with nasm -felf64 will make a 64-bit object file, but the hello world example below uses 32-bit system calls, and won't work in a PIE executable.)

Here is some more info:

http://www.nasm.us/doc/nasmdoc2.html#section-2.1

You can install NASM in Ubuntu with the following command:

apt-get install nasm

I hope this is what you were asking...

If you're encoding a string to put in a URL component (a querystring parameter), you should call encodeURIComponent.

If you're encoding an existing URL, call encodeURI.

var tv = findViewById(R.id.tv) as TextView

    tv.setOnClickListener {
       val i = Intent(this@MainActivity, SecondActivity::class.java)
       startActivity(i)
       finish()
    }

var demoArray = ['A','B','C','D'];
var ArrayIndexValue = 2;
if(ArrayIndexValue in demoArray){
   //Array index exists
}else{
   //Array Index does not Exists
}

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

Yes, the "is" keyword:

if (c is TForm)
{
    ...
}

See details on MSDN: http://msdn.microsoft.com/en-us/library/scekt9xw(VS.80).aspx

Checks if an object is compatible with a given type. For example, it can be determined if an object is compatible with the string type like this:

Guava cache is easy to implementation.We can expires key on time base using guava cache. I have read fully post and below gives key of my study.

cache = CacheBuilder.newBuilder().refreshAfterWrite(2,TimeUnit.SECONDS).
              build(new CacheLoader<String, String>(){
                @Override
                public String load(String arg0) throws Exception {
                    // TODO Auto-generated method stub
                    return addcache(arg0);
                }

              }

checking with isinstance() would not be enough if you want to know in run time. use:

if(someObject.getClass().equals(C.class){
    // do something
}

It would seem overkill but Spring Forms handles this elegantly. That is of course if you are already using Spring MVC and you want to take advantage of the Spring Forms feature.

// jsp form
    <form:select path="friendlyNumber" items="${friendlyNumberItems}" />

    // the command class
    public class NumberCmd {
      private String[] friendlyNumber;
    }

    // in your Spring MVC controller submit method
    @RequestMapping(method=RequestMethod.POST)
    public String manageOrders(@ModelAttribute("nbrCmd") NumberCmd nbrCmd){

       String[] selectedNumbers = nbrCmd.getFriendlyNumber();

    }

if your date filed is timestamp into database then this is the easy way to get record

$this->db->where('DATE(RecordDate) >=', date('Y-m-d',strtotime($startDate)));
$this->db->where('DATE(RecordDate) <=', date('Y-m-d',strtotime($endDate)));

%02x means print at least 2 digits, prepend it with 0's if there's less. In your case it's 7 digits, so you get no extra 0 in front.

Also, %x is for int, but you have a long. Try %08lx instead.

If you want happen to be using LESS it can be achieved like so:

li {
    .glyphicon-ok();

    &:before {            
        .glyphicon();            
        margin-left:-25px;
       float:left;
    }
}

Robomongo 0.8.5 definitely works with MongoDB 3.X (mine version of MongoDB is 3.0.7, the newest one).

The following steps should be done to connect to the MongoDB server:

1. Install MongoDB server (on Windows, Linux, etc. Your choice)
2. Run the MongoDB server. Don't set net.bind_ip = 127.0.0.1 if you want the client to connect to the server by server's own IP address!
3. Connect to the server from Robomongo with the server IP address + set authentication if needed.

That whole Open <file path> For Input As <some number> thing is so 1990s. It's also slow and very error-prone.

In your VBA editor, Select References from the Tools menu and look for "Microsoft Scripting Runtime" (scrrun.dll) which should be available on pretty much any XP or Vista machine. It it's there, select it. Now you have access to a (to me at least) rather more robust solution:

With New Scripting.FileSystemObject
    With .OpenTextFile(sFilename, ForReading)

        If Not .AtEndOfStream Then .SkipLine
        If Not .AtEndOfStream Then .SkipLine

        Do Until .AtEndOfStream
            DoSomethingImportantTo .ReadLine
        Loop

    End With
End With

You can do this

.footer {
  position: absolute;
  right: 0;
  bottom: 0;
  left: 0;
  padding: 1rem;
  text-align: center;
}

It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.

I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.

It just helps to apply blanket CSS rules.

It's pretty straightforward with some simple rules:

• Whenever you create a promise in a then, return it - any promise you don't return will not be waited for outside.
• Whenever you create multiple promises, .all them - that way it waits for all the promises and no error from any of them are silenced.
• Whenever you nest thens, you can typically return in the middle - then chains are usually at most 1 level deep.
• Whenever you perform IO, it should be with a promise - either it should be in a promise or it should use a promise to signal its completion.

And some tips:

• Mapping is better done with .map than with for/push - if you're mapping values with a function, map lets you concisely express the notion of applying actions one by one and aggregating the results.
• Concurrency is better than sequential execution if it's free - it's better to execute things concurrently and wait for them Promise.all than to execute things one after the other - each waiting before the next.

Ok, so let's get started:

var items = [1, 2, 3, 4, 5];
var fn = function asyncMultiplyBy2(v){ // sample async action
    return new Promise(resolve => setTimeout(() => resolve(v * 2), 100));
};
// map over forEach since it returns

var actions = items.map(fn); // run the function over all items

// we now have a promises array and we want to wait for it

var results = Promise.all(actions); // pass array of promises

results.then(data => // or just .then(console.log)
    console.log(data) // [2, 4, 6, 8, 10]
);

// we can nest this of course, as I said, `then` chains:

var res2 = Promise.all([1, 2, 3, 4, 5].map(fn)).then(
    data => Promise.all(data.map(fn))
).then(function(data){
    // the next `then` is executed after the promise has returned from the previous
    // `then` fulfilled, in this case it's an aggregate promise because of 
    // the `.all` 
    return Promise.all(data.map(fn));
}).then(function(data){
    // just for good measure
    return Promise.all(data.map(fn));
});

// now to get the results:

res2.then(function(data){
    console.log(data); // [16, 32, 48, 64, 80]
});

Use Math.floor():

var f = 20.536;
var i = Math.floor(f);  // 20

If using Guava library, there are methods Ints.checkedCast(long) and Ints.saturatedCast(long) for converting long to int.

Above answers are in python2. So for python 3 users I am giving this answer. You can use the bellow code:

import pandas as pd
fields = ['star_name', 'ra']

df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print(df.keys())
# See content in 'star_name'
print(df.star_name)

You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade.

Simply paste the following code in your web.config file.

Noted that, you have to paste the following code under <system.webServer> tag

    <httpProtocol>  
    <customHeaders>  
     <add name="Access-Control-Allow-Origin" value="*" />  
     <add name="Access-Control-Allow-Headers" value="Content-Type" />  
     <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />  
    </customHeaders>  
  </httpProtocol>  

I had the same problem. I believe it's a privilege problem. If you have "Run only when user is logged on" selected, then it won't happen.

You've hopefully figured it out by now, but I wanted to register it here for the next person who has wasted hours on this.

man 7 daemon describes how to create daemon in great detail. My answer is just excerpt from this manual.

There are at least two types of daemons:

1. traditional SysV daemons (old-style),
2. systemd daemons (new-style).

SysV Daemons

If you are interested in traditional SysV daemon, you should implement the following steps:

1. Close all open file descriptors except standard input, output, and error (i.e. the first three file descriptors 0, 1, 2). This ensures that no accidentally passed file descriptor stays around in the daemon process. On Linux, this is best implemented by iterating through /proc/self/fd, with a fallback of iterating from file descriptor 3 to the value returned by getrlimit() for RLIMIT_NOFILE.
2. Reset all signal handlers to their default. This is best done by iterating through the available signals up to the limit of _NSIG and resetting them to SIG_DFL.
3. Reset the signal mask using sigprocmask().
4. Sanitize the environment block, removing or resetting environment variables that might negatively impact daemon runtime.
5. Call fork(), to create a background process.
6. In the child, call setsid() to detach from any terminal and create an independent session.
7. In the child, call fork() again, to ensure that the daemon can never re-acquire a terminal again.
8. Call exit() in the first child, so that only the second child (the actual daemon process) stays around. This ensures that the daemon process is re-parented to init/PID 1, as all daemons should be.
9. In the daemon process, connect /dev/null to standard input, output, and error.
10. In the daemon process, reset the umask to 0, so that the file modes passed to open(), mkdir() and suchlike directly control the access mode of the created files and directories.
11. In the daemon process, change the current directory to the root directory (/), in order to avoid that the daemon involuntarily blocks mount points from being unmounted.
12. In the daemon process, write the daemon PID (as returned by getpid()) to a PID file, for example /run/foobar.pid (for a hypothetical daemon "foobar") to ensure that the daemon cannot be started more than once. This must be implemented in race-free fashion so that the PID file is only updated when it is verified at the same time that the PID previously stored in the PID file no longer exists or belongs to a foreign process.
13. In the daemon process, drop privileges, if possible and applicable.
14. From the daemon process, notify the original process started that initialization is complete. This can be implemented via an unnamed pipe or similar communication channel that is created before the first fork() and hence available in both the original and the daemon process.
15. Call exit() in the original process. The process that invoked the daemon must be able to rely on that this exit() happens after initialization is complete and all external communication channels are established and accessible.

Note this warning:

The BSD daemon() function should not be used, as it implements only a subset of these steps.

A daemon that needs to provide compatibility with SysV systems should implement the scheme pointed out above. However, it is recommended to make this behavior optional and configurable via a command line argument to ease debugging as well as to simplify integration into systems using systemd.

Note that daemon() is not POSIX compliant.

New-Style Daemons

For new-style daemons the following steps are recommended:

1. If SIGTERM is received, shut down the daemon and exit cleanly.
2. If SIGHUP is received, reload the configuration files, if this applies.
3. Provide a correct exit code from the main daemon process, as this is used by the init system to detect service errors and problems. It is recommended to follow the exit code scheme as defined in the LSB recommendations for SysV init scripts.
4. If possible and applicable, expose the daemon's control interface via the D-Bus IPC system and grab a bus name as last step of initialization.
5. For integration in systemd, provide a .service unit file that carries information about starting, stopping and otherwise maintaining the daemon. See systemd.service(5) for details.
6. As much as possible, rely on the init system's functionality to limit the access of the daemon to files, services and other resources, i.e. in the case of systemd, rely on systemd's resource limit control instead of implementing your own, rely on systemd's privilege dropping code instead of implementing it in the daemon, and similar. See systemd.exec(5) for the available controls.
7. If D-Bus is used, make your daemon bus-activatable by supplying a D-Bus service activation configuration file. This has multiple advantages: your daemon may be started lazily on-demand; it may be started in parallel to other daemons requiring it — which maximizes parallelization and boot-up speed; your daemon can be restarted on failure without losing any bus requests, as the bus queues requests for activatable services. See below for details.
8. If your daemon provides services to other local processes or remote clients via a socket, it should be made socket-activatable following the scheme pointed out below. Like D-Bus activation, this enables on-demand starting of services as well as it allows improved parallelization of service start-up. Also, for state-less protocols (such as syslog, DNS), a daemon implementing socket-based activation can be restarted without losing a single request. See below for details.
9. If applicable, a daemon should notify the init system about startup completion or status updates via the sd_notify(3) interface.
10. Instead of using the syslog() call to log directly to the system syslog service, a new-style daemon may choose to simply log to standard error via fprintf(), which is then forwarded to syslog by the init system. If log levels are necessary, these can be encoded by prefixing individual log lines with strings like "<4>" (for log level 4 "WARNING" in the syslog priority scheme), following a similar style as the Linux kernel's printk() level system. For details, see sd-daemon(3) and systemd.exec(5).

One way to insert text inside a rectangle is to insert a foreign object, wich is a DIV, inside rect object.

In addition to specifying the path (as Jimmy mentioned) you can also force Bundler to use a local gem for your environment only by using the following configuration option:

$ bundle config local.GEM_NAME /path/to/local/git/repository

This is extremely helpful if you're developing two gems or a gem and a rails app side-by-side.

Note though, that this only works when you're already using git for your dependency, for example:

# In Gemfile
gem 'rack', :github => 'rack/rack', :branch => 'master'

# In your terminal
$ bundle config local.rack ~/Work/git/rack

As seen on the docs.

A later answer, but because no one gave this solution...

If you do not want to set the header on the HttpClient instance by adding it to the DefaultRequestHeaders, you could set headers per request.

But you will be obliged to use the SendAsync() method.

This is the right solution if you want to reuse the HttpClient -- which is a good practice for

• performance and port exhaustion problems
• doing something thread-safe
• not sending the same headers every time

Use it like this:

using (var requestMessage =
            new HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
{
    requestMessage.Headers.Authorization =
        new AuthenticationHeaderValue("Bearer", your_token);
    httpClient.SendAsync(requestMessage);
}

For a more graceful way, try the following:

Caveat: I'm running Debian 7, not Ubuntu, though it is a Debian derivative

If you're running Tomcat as a service, you can get a list of all running services by typing:

sudo service --status-all

I'm running Tomcat 7, which is displayed as tomcat7 in said list. Then, to shut it down just type:

sudo service tomcat7 stop

Use IPython display to render PIL images in a notebook.

from PIL import Image               # to load images
from IPython.display import display # to display images

pil_im = Image.open('path/to/image.jpg')
display(pil_im)

Javascript's inheritance is prototype based, so you extend the prototypes of objects such as Date, Math, and even your own custom ones.

Date.prototype.lol = function() {
 alert('hi');
};

( new Date ).lol() // alert message

In the snippet above, I define a method for all Date objects ( already existing ones and all new ones ).

extend is usually a high level function that copies the prototype of a new subclass that you want to extend from the base class.

So you can do something like:

extend( Fighter, Human )

And the Fighter constructor/object will inherit the prototype of Human, so if you define methods such as live and die on Human then Fighter will also inherit those.

Updated Clarification:

"high level function" meaning .extend isn't built-in but often provided by a library such as jQuery or Prototype.

The MySQL dependency should be like the following syntax in the pom.xml file.

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.21</version>
    </dependency>

Make sure the syntax, groupId, artifactId, Version has included in the dependancy.

1752 was the year of Britain switching from the Julian to the Gregorian calendar. I believe two weeks in September 1752 never happened as a result, which has implications for dates in that general area.

The issue is fixed by adding repository url under distributionManagement tab in main pom.xml.

I had same problem and in my case this was because curl_exec function is disabled in php.ini. Check for logs:

PHP Warning:  curl_exec() has been disabled for security reasons in /var/www/***/html/test.php on line 18

Solution is remove curl_exec from disabled functions in php.ini on server configuration file.

An AXD file is a file used by ASP.NET applications for handling embedded resource requests. It contains instructions for retrieving embedded resources, such as images, JavaScript (.JS) files, and.CSS files. AXD files are used for injecting resources into the client-side webpage and access them on the server in a standard way.

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

Some answers uses each, but map is a better alternative here IMHO:

$("select#example option").map(function() {return $(this).val();}).get();

There are (at least) two map functions in jQuery. Thomas Petersen's answer uses "Utilities/jQuery.map"; this answer uses "Traversing/map" (and therefore a little cleaner code).

It depends on what you are going to do with the values. If you, let's say, want to return the values from a function, map is probably the better alternative. But if you are going to use the values directly you probably want each.

Another solution (without selecting HTML DOM elements )

If you added 'change' event listener on that input, then in javascript code you can call (for some specified conditions):

event.target.value = '';

For example in HTML:

<input type="file" onChange="onChangeFunction(event)">

And in javascript:

onChangeFunction(event) {
  let fileList = event.target.files;
  let file = fileList[0];
  let extension = file.name.match(/(?<=\.)\w+$/g)[0].toLowerCase(); // assuming that this file has any extension

  if (extension === 'jpg') {
    alert('Good file extension!');
  }
  else {
    event.target.value = '';
    alert('Wrong file extension! File input is cleared.');
  }

Let's get a canonical answer here. I will reference the HTML5 spec.

First of all, 12.1.2.4 Optional tags:

A head element's start tag may be omitted if the element is empty, or if the first thing inside the head element is an element.

A head element's end tag may be omitted if the head element is not immediately followed by a space character or a comment.

A body element's start tag may be omitted if the element is empty, or if the first thing inside the body element is not a space character or a comment, except if the first thing inside the body element is a script or style element.

A body element's end tag may be omitted if the body element is not immediately followed by a comment.

Then, the 4.1.1 The html element:

Content model: A head element followed by a body element.

Having the cited restrictions and strictly defined element order, we can easily work out what are the rules for placing implicit <body> tag.

Since <head/> must come first, and it can contain elements only (and not direct text), all elements suitable for <head/> will become the part of implicit <head/>, up to the first stray text or <body/>-specific element. At that moment, all remaining elements and text nodes will be placed in <body/>.

Now let's consider your second snippet:

<html>
  <header>...</header>
  <body>
    <section>...</section>
    <section>...</section>
    <section>...</section>
  </body>
  <footer>...</footer>
</html>

Here, the <header/> element is not suitable for <head/> (it's flow content), the <body> tag will be placed immediately before it. In other words, the document will be understood by browser as following:

<html>
  <head/>
  <body>
    <header>...</header>
    <body>
      <section>...</section>
      <section>...</section>
      <section>...</section>
    </body>
    <footer>...</footer>
  </body>
</html>

And that's certainly not what you were expecting. And as a note, it is invalid as well; see 4.4.1 The body element:

Contexts in which this element can be used: As the second element in an html element.

[...]

In conforming documents, there is only one body element.

Thus, the <header/> or <footer/> will be correctly used in this context. Well, they will be practically equivalent to the first snippet. But this will cause an additional <body/> element in middle of a <body/> which is invalid.

As a side note, you're probably confusing <body/> here with the main part of the content which has no specific element. You could look up that page for other solutions on getting what you want.

Quoting 4.4.1 The body element once again:

The body element represents the main content of the document.

which means all the content. And both header and footer are part of this content.

Statically typed languages: each variable and expression is already known at compile time.

(int a; a can take only integer type values at runtime)

Examples: C, C++, Java

Dynamically typed languages: variables can receive different values at runtime and their type is defined at run time.

(var a; a can take any kind of values at runtime)

Examples: Ruby, Python.

Try this:

echo str_replace(array('\r\n', '\n\r', '\n', '\r'), '<br>', $description);

You can use a ResourceManager to load the image.

See the following link: http://www.java2s.com/Code/CSharp/Development-Class/Saveandloadimagefromresourcefile.htm

$('#new_user_form :input') should be your way forward. Note the omission of the > selector. A valid HTML form wouldn't allow for a input tag being a direct child of a form tag.

You can generate SASS file which imports everything automatically, I use this Gulp task:

concatFilenames = require('gulp-concat-filenames')

let concatFilenamesOptions = {
    root: './',
    prepend: "@import '",
    append: "'"
}
gulp.task('sass-import', () => {
    gulp.src(path_src_sass)
        .pipe(concatFilenames('app.sass', concatFilenamesOptions))
        .pipe(gulp.dest('./build'))
})

You can also control importing order by ordering the folders like this:

path_src_sass = [
    './style/**/*.sass', // mixins, variables - import first
    './components/**/*.sass', // singule components
    './pages/**/*.sass' // higher-level templates that could override components settings if necessary
]

SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

I think that i first validate form and if validation will pass, than i would make ajax post. Dont forget to add "return false" at the end of the script.

No arguments in DIVs favour from me.

I'd say : If the shoe fits, wear it.

It's worth noting that it's difficult if not impossible to find a good DIV+CSS method of rendering contents in two or three columns, that is consistent on all browsers, and still looks just the way I intended.

This tips the balance a bit towards tables in most of my layouts, and altough I feel guilty of using them (dunny why, people just say it's bad so I try to listen to them), in the end , the pragmatic view is it's just easier and faster for me to use TABLEs. I'm not being payed by the hour, so tables are cheaper for me.

if I understand you right (not sure), the start parameter /D should help you:

start "cmd" /D %PathName% %comd%

/D sets the start-directory (see start /?)

After the C# 6.0 (including) you can use nameof expression:

using Stuff = Some.Cool.Functionality  
class C {  
    static int Method1 (string x, int y) {}  
    static int Method1 (string x, string y) {}  
    int Method2 (int z) {}  
    string f<T>() => nameof(T);  
}  

var c = new C()  

nameof(C) -> "C"  
nameof(C.Method1) -> "Method1"   
nameof(C.Method2) -> "Method2"  
nameof(c.Method1) -> "Method1"   
nameof(c.Method2) -> "Method2"  
nameof(z) -> "z" // inside of Method2 ok, inside Method1 is a compiler error  
nameof(Stuff) = "Stuff"  
nameof(T) -> "T" // works inside of method but not in attributes on the method  
nameof(f) -> “f”  
nameof(f<T>) -> syntax error  
nameof(f<>) -> syntax error  
nameof(Method2()) -> error “This expression does not have a name”  

Note! nameof not get the underlying object's runtime Type, it is just the compile-time argument. If a method accepts an IEnumerable then nameof simply returns "IEnumerable", whereas the actual object could be "List".

best way for Python 3 is:

pip3 freeze > requirements.txt

it worked for me...

If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:

gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary

There's a caveat -- if liborangejuice uses libapplejuice, then libapplejuice will be dynamically linked too.

You'll have to link liborangejuice statically alongside with libapplejuice to get libapplejuice static.

And don't forget to keep -Wl,-Bdynamic else you'll end up linking everything static, including libc (which isn't a good thing to do).

if you are a exists project, maybe should execute npm install.

Same issue:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.util.UUID` out of START_OBJECT token

What caused it was the following:

ResponseEntity<UUID> response = restTemplate.postForEntity("/example/", null, UUID.class);

In my test I purposely set the request as null (no content POST). As previously mentioned, the cause for the OP was the same because the request didn't contain a valid JSON, so it couldn't be automatically identified as an application/json request which was the limitation on the server (consumes = "application/json"). A valid JSON request would be. What fixed it was populating an entity with null body and json headers explicitly.

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity request = new HttpEntity<>(null, headers);
ResponseEntity<UUID> response = restTemplate.postForEntity("/example/", request, UUID.class);

Alternatively you can create your own afxres.h:

#ifndef _AFXRES_H
#define _AFXRES_H
#if __GNUC__ >= 3
#pragma GCC system_header
#endif

#ifdef __cplusplus
extern "C" {
#endif

#ifndef _WINDOWS_H
#include <windows.h>
#endif

/* IDC_STATIC is documented in winuser.h, but not defined. */
#ifndef IDC_STATIC
#define IDC_STATIC (-1)
#endif

#ifdef __cplusplus
}
#endif
#endif   

Since .NET 3.0, you can simply use *yourElement*.TranslatePoint(new Point(0, 0), *theContainerOfYourChoice*).

This will give you the point 0, 0 of your button, but towards the container. (You can also give an other point that 0, 0)

Check here for the doc.

You shouldn't have to care that much. RFC 3339, according to itself, is a set of standards derived from ISO 8601. There's quite a few minute differences though, and they're all outlined in RFC 3339. I could go through them all here, but you'd probably do better just reading the document for yourself in the event you're worried:

http://tools.ietf.org/html/rfc3339

Another one line command I used is:

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

In order to make dir more useful (in the case a local file with no path is specified as input) I did the following:

# Substring from 0 thru pos of filename
dir="${fullpath:0:${#fullpath} - ${#filename}}"
if [[ -z "$dir" ]]; then
    dir="./"
fi

This allows you to do something useful like add a suffix to the input file basename as:

outfile=${dir}${base}_suffix.${ext}

testcase: foo.bar
dir: "./"
base: "foo"
ext: "bar"
outfile: "./foo_suffix.bar"

testcase: /home/me/foo.bar
dir: "/home/me/"
base: "foo"
ext: "bar"
outfile: "/home/me/foo_suffix.bar"

Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.

Here's an example:

<section class="content">            
    <div class="modal"></div>
</section>

<div class="side-tab"></div>

// CSS //
.content {
    position: relative;
    z-index: 1;
}

.modal {
    position: fixed;
    z-index: 100;
}

.side-tab {
    position: fixed;
    z-index: 5;
}

In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.

Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

This is a crazy thing of apple. When you say self.navigationItem.rightBarButtonItem.title then it will say nil while on the GUI it shows Edit or Save. Fresher likes me will take a lot of time to debug this behavior.

There is a requirement that the Item will show Edit in the firt load then user taps on it It will change to Save title. To archive this, i did as below.

//view did load will say Edit title

private func loadRightBarItem() {
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
}

// tap Edit item will change to Save title

@objc private func handleEditBtn() {
    print("clicked on Edit btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Save", style: .done, target: self, action: #selector(handleSaveBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
    blockEditTable(isBlock: false)
}

//tap Save item will display Edit title

@objc private func handleSaveBtn(){
    print("clicked on Save btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem

    saveInvitation()
    blockEditTable(isBlock: true)

}

Try using an xml or a vector asset instead of a jpg or png.

The reason is quite obvious in the exception name itself i.e. the resolution of the resource is too large to render.

You can png to xml using online tools like https://svg2vector.com/ OR add your image to drawable-xxhdpi folder.

Instead of using XML to add margin between items in RecyclerView, it's better way to use RecyclerView.ItemDecoration that provide by android framework.

So, I create a library to solve this issue.

Resizing canvas using css is not a good idea. It should be done using Javascript. See the below function which does it

function setCanvas(){

   var canvasNode = document.getElementById('xCanvas');

   var pw = canvasNode.parentNode.clientWidth;
   var ph = canvasNode.parentNode.clientHeight;

   canvasNode.height = pw * 0.8 * (canvasNode.height/canvasNode.width);  
   canvasNode.width = pw * 0.8;
   canvasNode.style.top = (ph-canvasNode.height)/2 + "px";
   canvasNode.style.left = (pw-canvasNode.width)/2 + "px";


}

A great blog describing 14 address finders: https://www.conversion-uplift.co.uk/free-address-lookup-tools/

Many address autocomplete services, including Google's Places API, appears to offer international address support but it has limited accuracy.

For example, New Zealand address and geolocation data are free to download from Land Information New Zealand (LINZ). When a user search for an address such as 76 Francis St Hauraki from Google or Address Doctor, a positive match is returned. The land parcel was matched but not the postal/delivery address, which is either 76A or 76B. The problem is amplified with apartments and units on a single land parcel.

For 100% accuracy, use a country-specific address finder instead such as https://www.addy.co.nz for NZ address autocomplete.

That's exactly how you use it. There is a possibility that the address you have does not correspond to something directly in your source code though.

For example:

$ cat t.c
#include <stdio.h>
int main()
{
    printf("hello\n");
    return 0;
}
$ gcc -g t.c
$ addr2line -e a.out 0x400534
/tmp/t.c:3
$ addr2line -e a.out 0x400550
??:0

0x400534 is the address of main in my case. 0x400408 is also a valid function address in a.out, but it's a piece of code generated/imported by GCC, that has no debug info. (In this case, __libc_csu_init. You can see the layout of your executable with readelf -a your_exe.)

Other times when addr2line will fail is if you're including a library that has no debug information.

The ES6 way:

let people = [{firstName:'Alice',lastName:'Cooper'},{firstName:'Bob',age:'Dylan'}];
let names = Array.from(people, p => p.firstName);
for (let name of names) {
  console.log(name);
}

If you want to send background email, then please do the below

 public void SendEmail(string address, string subject, string message)
 {
 Thread threadSendMails;
 threadSendMails = new Thread(delegate()
    {

      //Place your Code here 

     });
  threadSendMails.IsBackground = true;
  threadSendMails.Start();
}

and add namespace

using System.Threading;

I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.

Just move the var inside the "name" block:

- name: Download apache
  vars:
    url: czxcxz
  shell: wget {{url}} 

I just found out that if your element id is just a number, then d3.select("1234"), will not work.

The unique id needs to be an alpha-numeric character.

d3.select("1234")

d3.select("container1234")

Use this one

public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));

@Test
public void testInsertObject() throws Exception { 
    String url = BASE_URL + "/object";
    ObjectBean anObject = new ObjectBean();
    anObject.setObjectId("33");
    anObject.setUserId("4268321");
    //... more
    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
    ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
    String requestJson=ow.writeValueAsString(anObject );

    mockMvc.perform(post(url).contentType(APPLICATION_JSON_UTF8)
        .content(requestJson))
        .andExpect(status().isOk());
}

As described in the comments, this works because the object is converted to json and passed as the request body. Additionally, the contentType is defined as Json (APPLICATION_JSON_UTF8).

More info on the HTTP request body structure

I think this is only partially true. Changing the format seems to switch the date to a string object which then has no methods like AddDays to manipulate it. So to make this work, you have to switch it back to a date. For example:

Get-Date (Get-Date).AddDays(-1) -format D

Annoyingly Javascript's date.getSeconds() et al will not pad the result with zeros 11:0:0 instead of 11:00:00.

So I like to use

date.toLocaleTimestring()

Which renders 11:00:00 AM. Just beware when using the extra options, some browsers don't support them (Safari)

I didnt want Static Url. I have AjaxFactory for doing all ajax operations. I am getting url from the factory and binding it as follows.

<a target="_self" href="{{ file.downloadUrl + '/' + order.OrderId + '/' + fileName }}" download="{{fileName}}">{{fileName}}</a>

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.

This is the same question as Failed to connect to mailserver at "localhost" port 25

also check this php mail function not working

There are several ways to append a list to a Pandas Dataframe in Python. Let's consider the following dataframe and list:

import pandas as pd
# Dataframe
df = pd.DataFrame([[1, 2], [3, 4]], columns = ["col1", "col2"])
# List to append
list = [5, 6]

Option 1: append the list at the end of the dataframe with ?pandas.DataFrame.loc.

df.loc[len(df)] = list

Option 2: convert the list to dataframe and append with ?pandas.DataFrame.append().

df = df.append(pd.DataFrame([list], columns=df.columns), ignore_index=True)

Option 3: convert the list to series and append with ??pandas.DataFrame.append()?.

df = df.append(pd.Series(list, index = df.columns), ignore_index=True)

Each of the above options should output something like:

>>> print (df)
   col1  col2
0     1     2
1     3     4
2     5     6

Reference : How to append a list as a row to a Pandas DataFrame in Python?

You're going to end up doing alot of string manipulation anyway, so why not just manipulate the date string itself?

Browsers format the date string differently.

Netscape ::: Fri May 11 2012 20:15:49 GMT-0600 (Mountain Daylight Time)

IE ::: Fri May 11 20:17:33 MDT 2012

so you'll have to check for that.

var D = new Date().toString().split(' ')[(document.all)?3:4];

That will set D equal to the 24-hour HH:MM:SS string. Split that on the colons, and the first element will be the hours.

var H = new Date().toString().split(' ')[(document.all)?3:4].split(':')[0];

You can convert 24-hour hours into 12-hour hours, but that hasn't actually been mentioned here. Probably because it's fairly CRAZY what you're actually doing mathematically when you convert hours from clocks. In fact, what you're doing is adding 23, mod'ing that by 12, and adding 1

twelveHour = ((twentyfourHour+23)%12)+1;

So, for example, you could grab the whole time from the date string, mod the hours, and display all that with the new hours.

var T = new Date().toString().split(' ')[(document.all)?3:4].split(':');
T[0] = (((T[0])+23)%12)+1;
alert(T.join(':'));

With some smart regex, you can probably pull the hours off the HH:MM:SS part of the date string, and mod them all in the same line. It would be a ridiculous line because the backreference $1 couldn't be used in calculations without putting a function in the replace.

Here's how that would look:

var T = new Date().toString().split(' ')[(document.all)?3:4].replace(/(^\d\d)/,function(){return ((parseInt(RegExp.$1)+23)%12)+1} );

Which, as I say, is ridiculous. If you're using a library that CAN perform calculations on backreferences, the line becomes:

var T = new Date().toString().split(' ')[(document.all)?3:4].replace(/(^\d\d)/, (($1+23)%12)+1);

And that's not actually out of the question as useable code, if you document it well. That line says:

Make a Date string, break it up on the spaces, get the browser-apropos part, and replace the first two-digit-number with that number mod'ed.

Point of the story is, the way to convert 24-hour-clock hours to 12-hour-clock hours is a non-obvious mathematical calculation:

You add 23, mod by 12, then add one more.

There is a default onhashchange event that you can use.

Documented HERE

And can be used like this:

function locationHashChanged( e ) {
    console.log( location.hash );
    console.log( e.oldURL, e.newURL );
    if ( location.hash === "#pageX" ) {
        pageX();
    }
}

window.onhashchange = locationHashChanged;

If the browser doesn't support oldURL and newURL you can bind it like this:

//let this snippet run before your hashChange event binding code
if( !window.HashChangeEvent )( function() {
    let lastURL = document.URL;
    window.addEventListener( "hashchange", function( event ) {
        Object.defineProperty( event, "oldURL", { enumerable: true, configurable: true, value: lastURL } );
        Object.defineProperty( event, "newURL", { enumerable: true, configurable: true, value: document.URL } );
        lastURL = document.URL;
    } );
} () );

This code works fine:

import os


def readFile(filename):
    filehandle = open(filename)
    print filehandle.read()
    filehandle.close()



fileDir = os.path.dirname(os.path.realpath('__file__'))
print fileDir

#For accessing the file in the same folder
filename = "same.txt"
readFile(filename)

#For accessing the file in a folder contained in the current folder
filename = os.path.join(fileDir, 'Folder1.1/same.txt')
readFile(filename)

#For accessing the file in the parent folder of the current folder
filename = os.path.join(fileDir, '../same.txt')
readFile(filename)

#For accessing the file inside a sibling folder.
filename = os.path.join(fileDir, '../Folder2/same.txt')
filename = os.path.abspath(os.path.realpath(filename))
print filename
readFile(filename)

FYI: In order for @Vadim's answer to work with a manual unwind seque action called from within a View Controller you must place the command:

[self performSegueWithIdentifier:(NSString*) identifier sender:(id) sender];

inside of the overriden class method viewDidAppear like so:

-(void) viewDidAppear:(BOOL) animated
{
    [super viewDidAppear: animated];

    [self performSegueWithIdentifier:@"SomeSegueIdentifier" sender:self];
}

If you put it in other ViewController methods like viewDidLoad or viewWillAppear it will be ignored.

do a phpinfo(), and look for session.save_path. the directory there needs to have the correct permissions for the user and/or group that your webserver runs as

@Alex Martelli's answer is great! But it work only for one element at time (WHERE name = 'Joan') If you take out the WHERE clause, the query will return all the root rows together...

I changed a little bit for my situation, so it can show the entire tree for a table.

table definition:

CREATE TABLE [dbo].[mar_categories] ( 
    [category]  int IDENTITY(1,1) NOT NULL,
    [name]      varchar(50) NOT NULL,
    [level]     int NOT NULL,
    [action]    int NOT NULL,
    [parent]    int NULL,
    CONSTRAINT [XPK_mar_categories] PRIMARY KEY([category])
)

(level is literally the level of a category 0: root, 1: first level after root, ...)

and the query:

WITH n(category, name, level, parent, concatenador) AS 
(
    SELECT category, name, level, parent, '('+CONVERT(VARCHAR (MAX), category)+' - '+CONVERT(VARCHAR (MAX), level)+')' as concatenador
    FROM mar_categories
    WHERE parent is null
        UNION ALL
    SELECT m.category, m.name, m.level, m.parent, n.concatenador+' * ('+CONVERT (VARCHAR (MAX), case when ISNULL(m.parent, 0) = 0 then 0 else m.category END)+' - '+CONVERT(VARCHAR (MAX), m.level)+')' as concatenador
    FROM mar_categories as m, n
    WHERE n.category = m.parent
)
SELECT distinct * FROM n ORDER BY concatenador asc

(You don't need to concatenate the level field, I did just to make more readable)

the answer for this query should be something like:

I hope it helps someone!

now, I'm wondering how to do this on MySQL... ^^

$ git clone

will give you the whole repository.

After the clone, you can list the tags with $ git tag -l and then checkout a specific tag:

$ git checkout tags/<tag_name>

Even better, checkout and create a branch (otherwise you will be on a branch named after the revision number of tag):

$ git checkout tags/<tag_name> -b <branch_name>

For those arriving here after updating phpunit to version 6 or greater released on 2017-02-03 (e.g. with composer), you may be getting this error because phpunit code is now namespaced (check changelog).

You will need to refactor things like \PHPUnit_Framework_TestCase to \PHPUnit\Framework\TestCase

String formatting, using the new-style .format() method (with the defaults .format() provides):

 '{}{}'.format(s, i)

Or the older, but "still sticking around", %-formatting:

 '%s%d' %(s, i)

In both examples above there's no space between the two items concatenated. If space is needed, it can simply be added in the format strings.

These provide a lot of control and flexibility about how to concatenate items, the space between them etc. For details about format specifications see this.

inspired from https://stackoverflow.com/a/10892768/2087666 but I use the selector instead of a class and prefer if over switch:

function clearAllInputs(selector) {
  $(selector).find(':input').each(function() {
    if(this.type == 'submit'){
          //do nothing
      }
      else if(this.type == 'checkbox' || this.type == 'radio') {
        this.checked = false;
      }
      else if(this.type == 'file'){
        var control = $(this);
        control.replaceWith( control = control.clone( true ) );
      }else{
        $(this).val('');
      }
   });
}

this should take care of almost all input inside any selector.

def rep(s, m):
    a, b = divmod(m, len(s))
    return s * a + s[:b]

The accepted answer is most likely a red herring. The difference between Django 1.2.4 and 1.2.5 was the requirement for a CSRF token for AJAX requests.

I came across this problem on Django 1.3 and it was caused by the CSRF cookie not being set in the first place. Django will not set the cookie unless it has to. So an exclusively or heavily ajax site running on Django 1.2.4 would potentially never have sent a token to the client and then the upgrade requiring the token would cause the 403 errors.

The ideal fix is here: http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#page-uses-ajax-without-any-html-form
but you'd have to wait for 1.4 unless this is just documentation catching up with the code

Edit

Note also that the later Django docs note a bug in jQuery 1.5 so ensure you are using 1.5.1 or later with the Django suggested code: https://docs.djangoproject.com/en/dev/ref/csrf/#ajax

Please try something like:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

You seem to have three main possible scenarios:

1. Space-separated date with time as text (eg as A1 below)
2. Hyphen-separated date as text (eg as A2 below)
3. Formatted date index (as A4 and A5 below)

ColumnA below is formatted General and ColumnB as Date (my default setting). ColumnC also as date but with custom formatting to suit the appearances mentioned in your question.
A clue as to whether or not text format is the left or right alignment of the cells’ contents.

I am suggesting separate treatment for each of the above three main cases, so use =IF to differentiate them.

Case #1

This is longer than any of the others, so can be distinguished as having a length greater than say 10 characters, with =LEN.
In this case we want all but the last six characters but for added flexibility (for instance, in case the time element included seconds) I have chosen to count from the left rather than from the right. The problem then is that the month names may vary in length, so I have chosen to look for the space that immediately follows the year to indicate the limit for the relevant number of characters.

This with =FIND which looks for a space (" ") in C1, starting with the eighth character within C1 counting from the left, on the assumption that for this case days will be expressed as two characters and months as three or more.

Since =LEFT is a string function it returns a string, but this can be converted to a value with=VALUE.

So

=VALUE(LEFT(C1,FIND(" ",C1,8))) 

returns 40671 in this example – in Excel’s 1900 date system the date serial number for May 5, 2011.

Case #2

If the length of C1 is not greater than 10 characters, we still need to distinguish between a text entry or a value entry which I have chosen to do with =ISTEXT and, where the if condition is TRUE (as for C2) apply =DATE which takes three parameters, here provided by:

=RIGHT(C2,4)  

Takes the last four characters of C2, hence 2011 in this example.

=MID(C2,4,2) 

Starting at the fourth character, takes the next two characters of C2, hence 05 in this example (representing May).

=LEFT(C2,2))  

Takes the first two characters of C2, hence 08 in this example (representing the 8th day of the month). Date is not a text function so does not need to be wrapped in =VALUE.

Taken together

=DATE(RIGHT(C2,4),MID(C2,4,2),LEFT(C2,2)) 

also returns 40671 in this example, but from different input from Case #1.

Case #3

Is simple because already a date serial number, so just

=C2  

is sufficient.

Put the above together to cover all three cases in a single formula:

=IF(LEN(C1)>10,VALUE(LEFT(C1,FIND(" ",C1,8))),IF(ISTEXT(C1),DATE(RIGHT(C1,4),MID(C1,4,2),LEFT(C1,2)),C1))  

as applied in ColumnF (formatted to suit OP) or in General format (to show values are integers) in ColumnH:

You can use MongoDB_DataObject wrapper to perform such query like below:

$model = new MongoDB_DataObject('orders');

$model->whereAdd('MONTH(created) = 4 AND YEAR(created) = 2016');

$model->find();

while ($model->fetch()) {
    var_dump($model);
}

OR, similarly, using direct query string:

$model = new MongoDB_DataObject();

$model->query('SELECT * FROM orders WHERE MONTH(created) = 4 AND YEAR(created) = 2016');

while ($model->fetch()) {
    var_dump($model);
}

An alternative is to use the maven shade plugin to build an uber-jar.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version> Your Version Here </version>
    <configuration>
            <!-- put your configurations here -->
    </configuration>
    <executions>
            <execution>
                    <phase>package</phase>
                    <goals>
                            <goal>shade</goal>
                    </goals>
            </execution>
    </executions>
</plugin>

"Perhaps I should leave it null"

Don't use magic numbers - it's bad practice - if you don't have a value leave it null

Otherwise if you really want a default date - use one of the other techniques posted to set a default date

This is another way of tackling the problem if you have long strings (like file path names) and you only want to break the strings on certain characters (like slashes). You can insert Unicode Zero Width Space characters just before (or after) the slashes in the HTML.

A modern approach to this is to use native standard based URLSearchParams. It's supported by all major browsers, except for IE where they're polyfills available

const paramsString = "site.fwx?position=1&archiveid=5000&columns=5&rows=20&sorting=ModifiedTimeAsc"
const searchParams = new URLSearchParams(paramsString);
searchParams.set('rows', 10);
console.log(searchParams.toString()); // return modified string.
