final

final can be used to mark a variable "unchangeable"

private final String name = "foo";  //the reference name can never change

final can also make a method not "overrideable"

public final String toString() {  return "NULL"; }

final can also make a class not "inheritable". i.e. the class can not be subclassed.

public final class finalClass {...}
public class classNotAllowed extends finalClass {...} // Not allowed

finally

finally is used in a try/catch statement to execute code "always"

lock.lock();
try {
  //do stuff
} catch (SomeException se) {
  //handle se
} finally {
  lock.unlock(); //always executed, even if Exception or Error or se
}

Java 7 has a new try with resources statement that you can use to automatically close resources that explicitly or implicitly implement java.io.Closeable or java.lang.AutoCloseable

finalize

finalize is called when an object is garbage collected. You rarely need to override it. An example:

protected void finalize() {
  //free resources (e.g. unallocate memory)
  super.finalize();
}

In C++ the finally is NOT required because of RAII.

RAII moves the responsibility of exception safety from the user of the object to the designer (and implementer) of the object. I would argue this is the correct place as you then only need to get exception safety correct once (in the design/implementation). By using finally you need to get exception safety correct every time you use an object.

Also IMO the code looks neater (see below).

Example:

A database object. To make sure the DB connection is used it must be opened and closed. By using RAII this can be done in the constructor/destructor.

C++ Like RAII

void someFunc()
{
    DB    db("DBDesciptionString");
    // Use the db object.

} // db goes out of scope and destructor closes the connection.
  // This happens even in the presence of exceptions.

The use of RAII makes using a DB object correctly very easy. The DB object will correctly close itself by the use of a destructor no matter how we try and abuse it.

Java Like Finally

void someFunc()
{
    DB      db = new DB("DBDesciptionString");
    try
    {
        // Use the db object.
    }
    finally
    {
        // Can not rely on finaliser.
        // So we must explicitly close the connection.
        try
        {
            db.close();
        }
        catch(Throwable e)
        {
           /* Ignore */
           // Make sure not to throw exception if one is already propagating.
        }
    }
}

When using finally the correct use of the object is delegated to the user of the object. i.e. It is the responsibility of the object user to correctly to explicitly close the DB connection. Now you could argue that this can be done in the finaliser, but resources may have limited availability or other constraints and thus you generally do want to control the release of the object and not rely on the non deterministic behavior of the garbage collector.

Also this is a simple example.
When you have multiple resources that need to be released the code can get complicated.

Java versions before version 7 allow for these three combinations of try-catch-finally...

try - catch
try - catch - finally
try - finally

finally block will be always executed no matter of what's going on in the try or/and catch block. so if there is no catch block, the exception won't be handled here.

However, you will still need an exception handler somewhere in your code - unless you want your application to crash completely of course. It depends on the architecture of your application exactly where that handler is.

• Java try block must be followed by either catch or finally block.
• For each try block there can be zero or more catch blocks, but only one finally block.
• The finally block will not be executed if program exits(either by calling System.exit() or by causing a fatal error that causes the process to abort).

Here is some code that show how it works.

class Test
{
    public static void main(String args[]) 
    { 
        System.out.println(Test.test()); 
    }

    public static String test()
    {
        try {
            System.out.println("try");
            throw new Exception();
        } catch(Exception e) {
            System.out.println("catch");
            return "return"; 
        } finally {  
            System.out.println("finally");
            return "return in finally"; 
        }
    }
}

The results is:

try
catch
finally
return in finally

Yet another alternative is double brace initialization, e.g.

new ArrayList<String>() {{ add(s); }};

but it is inefficient and obscure. Therefore only suitable:

• in code that doesn't mind memory leaks, such as most unit tests and other short-lived programs;
• and if none of the other solutions apply, which I think implies you've scrolled all the way down here looking to populate a different type of container than the ArrayList in the question.

For non-grouped elements, name and id should be same. In this case you gave name as 'sp' and id as 'sp_100'. Don't do that, do it like this:

HTML:

<input type="hidden" id="msg" name="msg" value="" style="display:none"/>
<input type="checkbox" name="sp" value="100" id="sp">

Javascript:

var Msg="abc";
document.getElementById('msg').value = Msg;
document.getElementById('sp').checked = true;

For more details

please visit : http://www.impressivewebs.com/avoiding-problems-with-javascript-getelementbyid-method-in-internet-explorer-7/

You need to create the variable to assign the new value to, like this:

String str = string.replaceAll("abcd","dddd");

SQL is a standard and there are many database vendors like Microsoft,Oracle who implements this standard using their own proprietary language.

Microsoft uses T-SQL to implement SQL standard to interact with data whereas oracle uses PL/SQL.

JAR File Manifest Attributes for Security

The JAR file manifest contains information about the contents of the JAR file, including security and configuration information.

Add the attributes to the manifest before the JAR file is signed.
See Modifying a Manifest File in the Java Tutorial for information on adding attributes to the JAR manifest file.

Permissions Attribute

The Permissions attribute is used to verify that the permissions level requested by the RIA when it runs matches the permissions level that was set when the JAR file was created.

Use this attribute to help prevent someone from re-deploying an application that is signed with your certificate and running it at a different privilege level. Set this attribute to one of the following values:

• sandbox - runs in the security sandbox and does not require additional permissions.

• all-permissions - requires access to the user's system resources.

Changes to Security Slider:

The following changes to Security Slider were included in this release(7u51):

• Block Self-Signed and Unsigned applets on High Security Setting
• Require Permissions Attribute for High Security Setting
• Warn users of missing Permissions Attributes for Medium Security Setting

For more information, see Java Control Panel documentation.

Reason of the error is wrong initialization of the mysqli object. True construction would be like this:

$DBConnect = new mysqli("localhost","root","","Ladle");

// strip '\n' or read until EOF, return error if read error

        }                                                    
        if er != nil {                                       
            err = er

    }                                                        
    return                                                   
}                                    

Use the length property of the [String] type:

if ($dbUserName.length -gt 8) {
    Write-Output "Please enter more than 8 characters."
    $dbUserName = Read-Host "Re-enter database username"
}

Please note that you have to use -gt instead of > in your if condition. PowerShell uses the following comparison operators to compare values and test conditions:

• -eq = equals
• -ne = not equals
• -lt = less than
• -gt = greater than
• -le = less than or equals
• -ge = greater than or equals

Below is a relevant code example for Angular 4/5 with the new HttpClient.

import { HttpClient } from '@angular/common/http';
import { HttpHeaders } from '@angular/common/http';

public removeItem(item) {
    let options = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
      }),
      body: item,
    };

    return this._http
      .delete('/api/menu-items', options)
      .map((response: Response) => response)
      .toPromise()
      .catch(this.handleError);
  }

I have now been able to get Keyboard input in Swift by using the following:

In my main.swift file I declared a variable i and assigned to it the function GetInt() which I defined in Objective C. Through a so called Bridging Header where I declared the function prototype for GetInt I could link to main.swift. Here are the files:

main.swift:

var i: CInt = GetInt()
println("Your input is \(i) ");

Bridging Header:

#include "obj.m"

int GetInt();

obj.m:

#import <Foundation/Foundation.h>
#import <stdio.h>
#import <stdlib.h>

int GetInt()
{
    int i;
    scanf("%i", &i);
    return i;
}

In obj.m it is possible to include the c standard output and input, stdio.h, as well as the c standard library stdlib.h which enables you to program in C in Objective-C, which means there is no need for including a real swift file like user.c or something like that.

Hope I could help,

Edit: It is not possible to get String input through C because here I am using the CInt -> the integer type of C and not of Swift. There is no equivalent Swift type for the C char*. Therefore String is not convertible to string. But there are fairly enough solutions around here to get String input.

There is a method setText() which takes 3 arguments :

public void setText(String text, String charset, String subtype)
    throws MessagingException

Parameters:

text - the text content to set
charset - the charset to use for the text
subtype - the MIME subtype to use (e.g., "html")

NOTE: the subtype takes text after / in MIME types so for ex.

• text/html would be html
• text/css would be css
• and so on..

You can try this script out since you do not want to target the Xoom only. I don't have a Xoom, but should work.

function mobile_detect(mobile,tablet,mobile_redirect,tablet_redirect,debug) {
var ismobile = (/iphone|ipod|android|blackberry|opera|mini|windows\sce|palm|smartphone|iemobile/i.test(navigator.userAgent.toLowerCase()));
var istablet = (/ipad|android|android 3.0|xoom|sch-i800|playbook|tablet|kindle/i.test(navigator.userAgent.toLowerCase()));

if (debug == true) {
    alert(navigator.userAgent);
}

if (ismobile && mobile==true) {
    if (debug == true) {
        alert("Mobile Browser");
    }
    window.location = mobile_redirect;
} else if (istablet && tablet==true) {
    if (debug == true) {
        alert("Tablet Browser");
    }
    window.location = tablet_redirect;
}
}

I created a project on github. Check it out - https://github.com/codefuze/js-mobile-tablet-redirect. Feel free to submit issues if there is anything wrong!

It's the only solution to map a ManyToMany association : you need a join table between the two entities tables to map the association.

It's also used for OneToMany (usually unidirectional) associations when you don't want to add a foreign key in the table of the many side and thus keep it independent of the one side.

Search for @JoinTable in the hibernate documentation for explanations and examples.

The worst thing of using just

console.log({'some stuff': 2} + '\n' + 'something')

is that all stuff are converted to the string and if you need object to show you may see next:

[object Object]

Thus my variant is the next code:

console.log({'some stuff': 2},'\n' + 'something');

If you want to do this only once, then do it because The framework will call initState() method exactly once for each State object it creates.

 @override
  void initState() {
    super.initState();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

If you want to do this again and again like on back or navigate to a next screen and etc..., then do it because didChangeDependencies() Called when a dependency of this State object changes.

For example, if the previous call to build referenced an InheritedWidget that later changed, the framework would call this method to notify this object about the change.

This method is also called immediately after initState. It is safe to call BuildContext.dependOnInheritedWidgetOfExactType from this method.

 @override
  void didChangeDependencies() {
    super.didChangeDependencies();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

This is the your Callback function

executeAfterBuildComplete([BuildContext context]){
    print("Build Process Complete");
  }

SSL properties are set at the JVM level via system properties. Meaning you can either set them when you run the program (java -D....) Or you can set them in code by doing System.setProperty.

The specific keys you have to set are below:

javax.net.ssl.keyStore- Location of the Java keystore file containing an application process's own certificate and private key. On Windows, the specified pathname must use forward slashes, /, in place of backslashes.

javax.net.ssl.keyStorePassword - Password to access the private key from the keystore file specified by javax.net.ssl.keyStore. This password is used twice: To unlock the keystore file (store password), and To decrypt the private key stored in the keystore (key password).

javax.net.ssl.trustStore - Location of the Java keystore file containing the collection of CA certificates trusted by this application process (trust store). On Windows, the specified pathname must use forward slashes, /, in place of backslashes, \.

If a trust store location is not specified using this property, the SunJSSE implementation searches for and uses a keystore file in the following locations (in order):

1. $JAVA_HOME/lib/security/jssecacerts
2. $JAVA_HOME/lib/security/cacerts

javax.net.ssl.trustStorePassword - Password to unlock the keystore file (store password) specified by javax.net.ssl.trustStore.

javax.net.ssl.trustStoreType - (Optional) For Java keystore file format, this property has the value jks (or JKS). You do not normally specify this property, because its default value is already jks.

javax.net.debug - To switch on logging for the SSL/TLS layer, set this property to ssl.

In my case I was using the maven-dependency-plugin so in order to resolve the issue I had to add the following property:

  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

See Apache Maven Resources Plugin / Specifying a character encoding scheme

I have put something like this in my Controller class and it worked:

IdentityUser user = await userManager.FindByNameAsync(HttpContext.User.Identity.Name);

where userManager is an instance of Microsoft.AspNetCore.Identity.UserManager class (with all weird setup that goes with it).

Here is my solution, there is no way to use momemt.js.Here is DataTable with Two DatePickers for DateRange (To and From) Filter.

$.fn.dataTable.ext.search.push(
  function (settings, data, dataIndex) {
    var min = $('#min').datepicker("getDate");
    var max = $('#max').datepicker("getDate");
    var startDate = new Date(data[4]);
    if (min == null && max == null) { return true; }
    if (min == null && startDate <= max) { return true; }
    if (max == null && startDate >= min) { return true; }
    if (startDate <= max && startDate >= min) { return true; }
    return false;
  }
);
  

    

You can pass it as an environment variable like this. Generally Node is the host that it is running in. The hostname is defaulted to the host name of the node when it is created.

docker service create -e 'FOO={{.Node.Hostname}}' nginx  

Then you can do docker ps to get the process ID and look at the env

$ docker exec -it c81640b6d1f1 env                                                                                                                                    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=c81640b6d1f1
TERM=xterm
FOO=docker-desktop
NGINX_VERSION=1.17.4
NJS_VERSION=0.3.5
PKG_RELEASE=1~buster
HOME=/root

An example of usage would be with metricbeats so you know which node is having system issues which I put in https://github.com/trajano/elk-swarm:

  metricbeat:
    image: docker.elastic.co/beats/metricbeat:7.4.0
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /sys/fs/cgroup:/hostfs/sys/fs/cgroup:ro
      - /proc:/hostfs/proc:ro
      - /:/hostfs:ro
    user: root
    hostname: "{{.Node.Hostname}}"
    command:
      - -E
      - |
        metricbeat.modules=[
          {
            module:docker,
            hosts:[unix:///var/run/docker.sock],
            period:10s,
            enabled:true
          }
        ] 
      - -E
      - processors={1:{add_docker_metadata:{host:unix:///var/run/docker.sock}}} 
      - -E
      - output.elasticsearch.enabled=false
      - -E
      - output.logstash.enabled=true
      - -E
      - output.logstash.hosts=["logstash:5044"]

The short version of the page linked by D Shu (and without the horrible popover ads) is that this "waiting for device" problem happens when the USB device node is not accessible to your current user. The USB id is different in fastboot mode, so you can easily have permission to it in adb but not in fastboot.

To fix it (on Ubuntu; other systems may be slightly different):

Run lsusb -v | less and find the relevant section which will look something like this:

Bus 001 Device 027: ID 18d1:4e30 Google Inc. 
Couldn't open device, some information will be missing
Device Descriptor:
...
  idVendor           0x18d1 Google Inc.

Now do

sudo vi /etc/udev/rules.d/11-android.rules

it's ok if that file does not yet exist; create it with a line like this, inserting your own username and vendor id:

SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", MODE="0640", OWNER="mbp"

then

sudo service udev restart

then verify the device node permissions have changed:

ls -Rl /dev/bus/usb

The even shorter cheesy version is to just run fastboot as root. But then you need to run every command that talks to the device as root, which tends to cause other complications. Simpler just to fix the permissions in the long run.

Well in JavaScript you can check two strings for values same as integers so yo can do this:

• "A" < "B"
• "A" == "B"
• "A" > "B"

And therefore you can make your own function that checks strings the same way as the strcmp().

So this would be the function that does the same:

function strcmp(a, b)
{   
    return (a<b?-1:(a>b?1:0));  
}

if You are using browser it default always works on get, u can work with postman tool,otherwise u can change it to getmapping.hope this will works

To quote the man:

The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables

Most often if you run crontab -e from X, you have VISUAL set; that's what is used. Try this:

VISUAL=vi crontab -e

It just worked for me :)

Something like this should do it:

for element in list_:
   sys.stdout.write(str(element))

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

Yes this is the way:

Right click on your program, select run -> run configuration then on vm argument

-Denv=EnvironmentName -Dcucumber.options="--tags @ifThereisAnyTag"

Then you can apply and close.

The best way is to store native JavaScript Date objects, which map onto BSON native Date objects.

> db.test.insert({date: ISODate()})
> db.test.insert({date: new Date()})
> db.test.find()
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:42.389Z") }
{ "_id" : ObjectId("..."), "date" : ISODate("2014-02-10T10:50:57.240Z") }

The native type supports a whole range of useful methods out of the box, which you can use in your map-reduce jobs, for example.

If you need to, you can easily convert Date objects to and from Unix timestamps¹⁾, using the getTime() method and Date(milliseconds) constructor, respectively.

¹⁾ Strictly speaking, the Unix timestamp is measured in seconds. The JavaScript Date object measures in milliseconds since the Unix epoch.

New and neat in Python 3.5:

[*map(chr, [66, 53, 0, 94])]

Thanks to Additional Unpacking Generalizations

UPDATE

Always seeking for shorter ways, I discovered this one also works:

*map(chr, [66, 53, 0, 94]),

Unpacking works in tuples too. Note the comma at the end. This makes it a tuple of 1 element. That is, it's equivalent to (*map(chr, [66, 53, 0, 94]),)

It's shorter by only one char from the version with the list-brackets, but, in my opinion, better to write, because you start right ahead with the asterisk - the expansion syntax, so I feel it's softer on the mind. :)

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

I did this for both "/xxxxx#asdf" and "#asdf" href anchors

$("a[href*=#]").on('click', function(event){
    var href = $(this).attr("href");
    if ( /(#.*)/.test(href) ){
      var hash = href.match(/(#.*)/)[0];
      var path = href.match(/([^#]*)/)[0];

      if (window.location.pathname == path || path.length == 0){
        event.preventDefault();
        $('html,body').animate({scrollTop:$(this.hash).offset().top}, 1000);
        window.location.hash = hash;
      }
    }
});

Ubuntu 14.04 LTS, in Amazon EC2. The following steps resolved this issue for me:

1. Edit server.xml and change port="8080" to "80"

sudo vi /var/lib/tomcat7/conf/server.xml

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

2. Edit tomcat7 file (if the file is not created then you need to create it)

sudo vi /etc/default/tomcat7

uncomment and change #AUTHBIND=no to yes

3. Install authbind

sudo apt-get install authbind

4. Run the following commands to provide tomcat7 read+execute on port 80.

sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown tomcat7 /etc/authbind/byport/80

5. Restart tomcat:

sudo /etc/init.d/tomcat7 restart

/dev/tty is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c in the ls -l output means.

man 4 tty or man -s 4 tty should give you more information, or you can read the man page online here.

Incidentally, pwd > /dev/tty doesn't necessarily print to the shell's stdout (though it is the pwd command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty still refers to the terminal.

You can also read from /dev/tty, which will normally read from the keyboard.

Simple and understandable

When you expand or collapse accordion it just adds/removes a class "in" and sets the height:auto or 0 to the accordion div.

Demo

So in your accordion when you define it just remove "in" class from the div as below. Whenever you expand an accorion it just adds the "in" class to make it visible.

If you render the page with "in" bootstrap looks for the class and it will make the div's height:auto, if it not present it will be at zero height.

<div id="collapseOne" class="accordion-body collapse">

You can use three different ways

1. ref / out parameters

using ref:

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    int add = 0;
    int multiply = 0;
    Add_Multiply(a, b, ref add, ref multiply);
    Console.WriteLine(add);
    Console.WriteLine(multiply);
}

private static void Add_Multiply(int a, int b, ref int add, ref int multiply)
{
    add = a + b;
    multiply = a * b;
}

using out:

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    int add;
    int multiply;
    Add_Multiply(a, b, out add, out multiply);
    Console.WriteLine(add);
    Console.WriteLine(multiply);
}

private static void Add_Multiply(int a, int b, out int add, out int multiply)
{
    add = a + b;
    multiply = a * b;
}

2. struct / class

using struct:

struct Result
{
    public int add;
    public int multiply;
}
static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.add);
    Console.WriteLine(result.multiply);
}

private static Result Add_Multiply(int a, int b)
{
    var result = new Result
    {
        add = a * b,
        multiply = a + b
    };
    return result;
}

using class:

class Result
{
    public int add;
    public int multiply;
}
static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.add);
    Console.WriteLine(result.multiply);
}

private static Result Add_Multiply(int a, int b)
{
    var result = new Result
    {
        add = a * b,
        multiply = a + b
    };
    return result;
}

3. Tuple

Tuple class

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.Item1);
    Console.WriteLine(result.Item2);
}

private static Tuple<int, int> Add_Multiply(int a, int b)
{
    var tuple = new Tuple<int, int>(a + b, a * b);
    return tuple;
}

C# 7 Tuples

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    (int a_plus_b, int a_mult_b) = Add_Multiply(a, b);
    Console.WriteLine(a_plus_b);
    Console.WriteLine(a_mult_b);
}

private static (int a_plus_b, int a_mult_b) Add_Multiply(int a, int b)
{
    return(a + b, a * b);
}

Either use the

$(document).on "page:load", attachRatingHandler

or use jQuery's .on function to achieve the same effect

$(document).on 'click', 'span.star', attachRatingHandler

Don't moveTo() after each lineTo()

In other words, remove every moveTo() except the first one.

Seriously, if I just copy-paste OP's code and remove the unnecessary moveTo() calls, it works.

Nothing else needs to be done.

EDIT: I know the OP already posted his "final working solution", but he didn't state why it works. The actual reason was quite surprising to me, so I felt the need to add an answer.

You can use this command:

grep -rn "string" *

n for showing line number with the filename r for recursive

In my case i have used following code for enabling gzip compression in apache web server.

  # Compress HTML File, CSS File, JavaScript File, Text File, XML File and Fonts
    AddOutputFilterByType DEFLATE text/plain
    AddOutputFilterByType DEFLATE text/html
    AddOutputFilterByType DEFLATE text/xml
    AddOutputFilterByType DEFLATE application/json
    AddOutputFilterByType DEFLATE application/x-httpd-php
    AddOutputFilterByType DEFLATE text/css
    AddOutputFilterByType DEFLATE application/xml
    AddOutputFilterByType DEFLATE application/xhtml+xml
    AddOutputFilterByType DEFLATE application/rss+xml
    AddOutputFilterByType DEFLATE application/javascript
    AddOutputFilterByType DEFLATE application/x-javascript
    AddOutputFilterByType DEFLATE font/otf
    AddOutputFilterByType DEFLATE font/ttf

I have taken reference from http://www.tutsway.com/enable-gzip-compression-using-htacess.php.

I made a library named AndroidImageSlider, you can have a try.

On my Ubuntu machine, I can see the output at /var/log/syslog.

On a RHEL/CentOS machine, the output is found in /var/log/messages.

This is controlled by the rsyslog service, so if this is disabled for some reason you may need to start it with systemctl start rsyslog.

As noted by others, your syslog() output would be logged by the /var/log/syslog file.
You can see system, user, and other logs at /var/log.

Edit:

This method should no longer be needed with the arrival of MVC 3, as it will be handled automatically - http://weblogs.asp.net/scottgu/archive/2010/07/27/introducing-asp-net-mvc-3-preview-1.aspx

You can use this ObjectFilter:

    public class ObjectFilter : ActionFilterAttribute {

    public string Param { get; set; }
    public Type RootType { get; set; }

    public override void OnActionExecuting(ActionExecutingContext filterContext) {
        if ((filterContext.HttpContext.Request.ContentType ?? string.Empty).Contains("application/json")) {
            object o =
            new DataContractJsonSerializer(RootType).ReadObject(filterContext.HttpContext.Request.InputStream);
            filterContext.ActionParameters[Param] = o;
        }

    }
}

You can then apply it to your controller methods like so:

    [ObjectFilter(Param = "postdata", RootType = typeof(ObjectToSerializeTo))]
    public JsonResult ControllerMethod(ObjectToSerializeTo postdata) { ... }

So basically, if the content type of the post is "application/json" this will spring into action and will map the values to the object of type you specify.

I do like below to :

var book: MutableList<Books> = mutableListOf()

/** Returns a new [MutableList] with the given elements. */

public fun <T> mutableListOf(vararg elements: T): MutableList<T>
    = if (elements.size == 0) ArrayList() else ArrayList(ArrayAsCollection(elements, isVarargs = true))

Following up to Isaac Turner's excellent answer, I'd like put an example based on K Closest Points to the Origin using max heap.

from math import sqrt
import heapq


class MaxHeapObj(object):
    def __init__(self, val):
        self.val = val.distance
        self.coordinates = val.coordinates

    def __lt__(self, other):
        return self.val > other.val

    def __eq__(self, other):
        return self.val == other.val

    def __str__(self):
        return str(self.val)


class MinHeap(object):
    def __init__(self):
        self.h = []

    def heappush(self, x):
        heapq.heappush(self.h, x)

    def heappop(self):
        return heapq.heappop(self.h)

    def __getitem__(self, i):
        return self.h[i]

    def __len__(self):
        return len(self.h)


class MaxHeap(MinHeap):
    def heappush(self, x):
        heapq.heappush(self.h, MaxHeapObj(x))

    def heappop(self):
        return heapq.heappop(self.h).val

    def peek(self):
        return heapq.nsmallest(1, self.h)[0].val

    def __getitem__(self, i):
        return self.h[i].val


class Point():
    def __init__(self, x, y):
        self.distance = round(sqrt(x**2 + y**2), 3)
        self.coordinates = (x, y)


def find_k_closest(points, k):
    res = [Point(x, y) for (x, y) in points]
    maxh = MaxHeap()

    for i in range(k):
        maxh.heappush(res[i])

    for p in res[k:]:
        if p.distance < maxh.peek():
            maxh.heappop()
            maxh.heappush(p)

    res = [str(x.coordinates) for x in maxh.h]
    print(f"{k} closest points from origin : {', '.join(res)}")


points = [(10, 8), (-2, 4), (0, -2), (-1, 0), (3, 5), (-2, 3), (3, 2), (0, 1)]
find_k_closest(points, 3)

import os, time, datetime

First, attempt to pull from the same refspec that you are trying to push to.

If this does not work, you can force a git push by using git push -f <repo> <refspec>, but use caution: this method can cause references to be deleted on the remote repository.

I often use row_number() as a quick way to discard duplicate records from my select statements. Just add a where clause. Something like...

select a,b,rn 
  from (select a, b, row_number() over (partition by a,b order by a,b) as rn           
          from table) 
 where rn=1;

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

On Linux (and probably most Unix), there is no OS-level DNS caching unless nscd is installed and running. Even then, the DNS caching feature of nscd is disabled by default at least in Debian because it's broken. The practical upshot is that your linux system very very probably does not do any OS-level DNS caching.

You could implement your own cache in your application (like they did for Squid, according to diegows's comment), but I would recommend against it. It's a lot of work, it's easy to get it wrong (nscd got it wrong!!!), it likely won't be as easily tunable as a dedicated DNS cache, and it duplicates functionality that already exists outside your application.

If an end user using your software needs to have DNS caching because the DNS query load is large enough to be a problem or the RTT to the external DNS server is long enough to be a problem, they can install a caching DNS server such as Unbound on the same machine as your application, configured to cache responses and forward misses to the regular DNS resolvers.

This solution uses a RandomAccessFile to only cache the portion of the file subsequent to the string to remove. It scans until it finds the String you want to remove. Then it copies all of the data after the found string, then writes it over the found string, and everything after. Last, it truncates the file size to remove the excess data.

public static long scanForString(String text, File file) throws IOException {
    if (text.isEmpty())
        return file.exists() ? 0 : -1;
    // First of all, get a byte array off of this string:
    byte[] bytes = text.getBytes(/* StandardCharsets.your_charset */);

    // Next, search the file for the byte array.
    try (DataInputStream dis = new DataInputStream(new FileInputStream(file))) {

        List<Integer> matches = new LinkedList<>();

        for (long pos = 0; pos < file.length(); pos++) {
            byte bite = dis.readByte();

            for (int i = 0; i < matches.size(); i++) {
                Integer m = matches.get(i);
                if (bytes[m] != bite)
                    matches.remove(i--);
                else if (++m == bytes.length)
                    return pos - m + 1;
                else
                    matches.set(i, m);
            }

            if (bytes[0] == bite)
                matches.add(1);
        }
    }
    return -1;
}

public static void remove(String text, File file) throws IOException {
    try (RandomAccessFile rafile = new RandomAccessFile(file, "rw");) {
        long scanForString = scanForString(text, file);
        if (scanForString == -1) {
            System.out.println("String not found.");
            return;
        }
        long remainderStartPos = scanForString + text.getBytes().length;
        rafile.seek(remainderStartPos);
        int remainderSize = (int) (rafile.length() - rafile.getFilePointer());
        byte[] bytes = new byte[remainderSize];
        rafile.read(bytes);
        rafile.seek(scanForString);

        rafile.write(bytes);
        rafile.setLength(rafile.length() - (text.length()));
    }
}

Usage:

File Contents: ABCDEFGHIJKLMNOPQRSTUVWXYZ

Method Call: remove("ABC", new File("Drive:/Path/File.extension"));

Resulting Contents: DEFGHIJKLMNOPQRSTUVWXYZ

This solution could easily be modified to remove with a certain, specifiable cacheSize, if memory is a concern. This would just involve iterating over the rest of the file to continually replace portions of size, cacheSize. Regardless, this solution is generally much better than caching an entire file in memory, or copying it to a temporary directory, etc.

To run app.js file check "main": "app.js" in your package.json file.

Then run command $ node app.js That should run your app and check.

The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:

package main

import (
    "fmt"
    "time"
    "strconv"
)

func main() {
    i, err := strconv.ParseInt("1405544146", 10, 64)
    if err != nil {
        panic(err)
    }
    tm := time.Unix(i, 0)
    fmt.Println(tm)
}

Output:

2014-07-16 20:55:46 +0000 UTC

Playground: http://play.golang.org/p/v_j6UIro7a

Edit:

Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.

you can use follow code in asp.net core 2.0:

public IActionResult index()
{
     return new ContentResult() { Content = "My error message", StatusCode = (int)HttpStatusCode.Unauthorized };
}

How can I switch between opened windows in Eclipse

CTRL+F7 works here - Eclipse Photon on Windows.

I had the same issue, but I simply solved it by adding -lm after the command that runs my code. Example. gcc code.c -lm

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

The above commands taken directly from this server fault answer

User data is very important for a good developer, so don't ask again and again for same data, use some logic to correct some basic error in data.

Before validation of Email: First you have to remove all illegal characters from email.

//This will Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

after that validate your email address using this filter_var() function.

filter_var($email, FILTER_VALIDATE_EMAIL)) // To Validate the email

For e.g.

<?php
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate email
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    echo $email." is a valid email address";
} else {
    echo $email." is not a valid email address";
}

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = UINavigationController(rootViewController: LoginViewController())

    return true

}

For MinGW this worked for me:

• Right click project, select Properties
• Go to C/C++ General - Paths and Symbols - Includes - GNU C++ - Include directories
• Select Add...
• Select Variables...
• Select MINGW_HOME and click OK
• Click Apply and OK

You should now see several MinGW paths in Includes in your project explorer.
The errors may not disappear instantly, you may need to refresh/build your project.

If you are using Cygwin, there could be an equivalent variable present.

you can use the new HTML 5 file api to read file contents

https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

but this won't work on every browser so you probably need a server side fallback.

I've located a solution that worked better for me, and which has the advantage of being usable with several images (case not illustrated in this example).

From @adeneo's answer on this question :

If you have an element with a background image, like this

<div id="test" style="background-image: url(link/to/image.png)"><div>

You can wait for the background to load by getting the image URL and using it for an image object in javascript with an onload handler

var src = $('#test').css('background-image');
var url = src.match(/\((.*?)\)/)[1].replace(/('|")/g,'');

var img = new Image();
img.onload = function() {
    alert('image loaded');
}
img.src = url;
if (img.complete) img.onload();

Outlook adds the signature to the new unmodified messages (you should not modify the body prior to that) when you call MailItem.Display (which causes the message to be displayed on the screen) or when you access the MailItem.GetInspector property - you do not have to do anything with the returned Inspector object, but Outlook will populate the message body with the signature.

Once the signature is added, read the HTMLBody property and merge it with the HTML string that you are trying to set. Note that you cannot simply concatenate 2 HTML strings - the strings need to be merged. E.g. if you want to insert your string at the top of the HTML body, look for the "<body" substring, then find the next occurrence of ">" (this takes care of the <body> element with attributes), then insert your HTML string after that ">".

Outlook Object Model does not expose signatures at all.

On a general note, the name of the signature is stored in the account profile data accessible through the IOlkAccountManager Extended MAPI interface. Since that interface is Extended MAPI, it can only be accessed using C++ or Delphi. You can see the interface and its data in OutlookSpy if you click the IOlkAccountManager button.
Once you have the signature name, you can read the HTML file from the file system (keep in mind that the folder name (Signatures in English) is localized.
Also keep in mind that if the signature contains images, they must also be added to the message as attachments and the <img> tags in the signature/message body adjusted to point the src attribute to the attachments rather than a subfolder of the Signatures folder where the images are stored.
It will also be your responsibility to merge the HTML styles from the signature HTML file with the styles of the message itself.

If using Redemption is an option, you can use its RDOAccount object (accessible in any language, including VBA). New message signature name is stored in the 0x0016001F property, reply signature is in 0x0017001F. You can also use the RDOAccount.ReplySignature and NewSignature properties.
Redemption also exposes RDOSignature.ApplyTo method that takes a pointer to the RDOMail object and inserts the signature at the specified location correctly merging the images and the styles:

set Session = CreateObject("Redemption.RDOSession")
Session.MAPIOBJECT = Application.Session.MAPIOBJECT
set Drafts = Session.GetDefaultFolder(olFolderDrafts)
set   Msg = Drafts.Items.Add
Msg.To =   "[email protected]"
Msg.Subject  = "testing signatures"
Msg.HTMLBody = "<html><body>some <b>bold</b> message text</body></html>"
set Account = Session.Accounts.GetOrder(2).Item(1)   'first mail account
if  Not (Account  Is  Nothing)  Then
     set Signature = Account.NewMessageSignature
     if  Not (Signature  Is  Nothing)  Then
       Signature.ApplyTo Msg,  false   'apply at the bottom
     End If
End If
Msg.Send

EDIT: as of July 2017, MailItem.GetInspector in Outlook 2016 no longer inserts the signature. Only MailItem.Display does.

If you want a fairly advanced tool to do some serious poking around, look at the Memory Analyzer project at Eclipse, contributed to them by SAP.

Some of what you can do is mind-blowingly good for finding memory leaks etc -- including running a form of limited SQL (OQL) against the in-memory objects, i.e.

SELECT toString(firstName) FROM com.yourcompany.somepackage.User

Totally brilliant.

1. Press Ctrl+H (Replace)

2. Select Extended from SearchMode

3. Put \r\n\r\n in Find What

4. Put \r\n in ReplaceWith

5. Click on Replace All

In my Notepad++ 7.2.2, the Preferences section it's a bit different.

The option is located at: Settings / Preferences / Language / Replace by space as in the Screenshot.

Another worthy optimization is the c_str ( ) member of the STL string classes, which returns an immutable null terminated string that can be passed around as a LPCTSTR, e. g., to a custom function that expects a LPCTSTR. Although I haven't traced through the destructor to confirm it, I suspect that the string class looks after the memory in which it creates the copy.

I just ran into this. As mentioned in this answer, using mode: "no-cors" will give you an opaque response, which doesn't seem to return data in the body.

opaque: Response for “no-cors” request to cross-origin resource. Severely restricted.

In my case I was using Express. After I installed cors for Express and configured it and removed mode: "no-cors", I was returned a promise. The response data will be in the promise, e.g.

fetch('http://example.com/api/node', {
  // mode: 'no-cors',
  method: 'GET',
  headers: {
    Accept: 'application/json',
  },
},
).then(response => {
  if (response.ok) {
    response.json().then(json => {
      console.log(json);
    });
  }
});

To remove trailing whitespace while also preserving whitespace-only lines, you want the regex to only remove trailing whitespace after non-whitespace characters. So you need to first check for a non-whitespace character. This means that the non-whitespace character will be included in the match, so you need to include it in the replacement.

Regex: ([^ \t\r\n])[ \t]+$

Replacement: \1 or $1, depending on the IDE

By default, the layouts in /res/layout are applied to both portrait and landscape.

If you have for example

/res/layout/main.xml

you can add a new folder /res/layout-land, copy main.xml into it and make the needed adjustments.

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

You can create several divs and do that:

<div style="width:100px; height:100px;">
   <div style="position:relative; top:0px; left:0px; width:100px; height:100px; opacity:0.3;"><img src="urltoimage" alt=" " /></div>
   <div style="position:relative; top:0px; left:0px; width:100px; height:100px;"> DIV with no opacity </div>
</div>

I did that couple times... Simple, yet effective...

You can change the actual width/height attributes like this:

var theImg = document.getElementById('theImgId');
theImg.height = 150;
theImg.width = 150;

For quick overview comparisons, I really like this website, that has many comparison pages, eg AWS DynamoDB vs MongoDB; http://db-engines.com/en/system/Amazon+DynamoDB%3BMongoDB

There is no such thing as "SOAP protocol". SOAP is an XML schema.

It usually runs over HTTP (port 80), however.

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

You will save yourself a heap of trouble (long term) if you store a ZIP Code as a character string, which it is, rather than a number, which it is not.

I prefer another approach if you are using mongo shell:

First as the another answers: use my_database_name then:

db.getCollectionNames().map( (name) => ({[name]: db[name].find().toArray().length}) )

This query will show you something like this:

[
        {
                "agreements" : 60
        },
        {
                "libraries" : 45
        },
        {
                "templates" : 9
        },
        {
                "users" : 19
        }
]

You can use similar approach with db.getCollectionInfos() it is pretty useful if you have so much data & helpful as well.

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.

Mostly you don't see a difference, unless you are using set -u:

/home/user1> var=""
/home/user1> echo $var

/home/user1> set -u
/home/user1> echo $var

/home/user1> unset var
/home/user1> echo $var
-bash: var: unbound variable

So really, it depends on how you are going to test the variable.

I will add that my preferred way of testing if it is set is:

[[ -n $var ]]  # True if the length of $var is non-zero

or

[[ -z $var ]]  # True if zero length

It is worth saying that the figure used for this setting is in BYTES - found that out the hard way!

You can use a bool combination query with must/must_not which gives great performance and returns all records where the field is not null and not empty.

bool must_not is like "NOT AND" which means field!="", bool must exist means its !=null.

so effectively enabling: where field1!=null and field1!=""

GET  IndexName/IndexType/_search
{
    "query": {
        "bool": {
            "must": [{
                "bool": {
                    "must_not": [{
                        "term": { "YourFieldName": ""}
                    }]
                }
            }, {
                "bool": {
                    "must": [{
                      "exists" : { "field" : "YourFieldName" }
                    }]
                }
            }]
        }   
    }
}

ElasticSearch Version:

  "version": {
    "number": "5.6.10",
    "lucene_version": "6.6.1"
  }

I have faced same issue, I resolved by adding "connection: close" as extention,

Step 1: create a new class ConnectionCloseExtension

import com.github.tomakehurst.wiremock.common.FileSource;
import com.github.tomakehurst.wiremock.extension.Parameters;
import com.github.tomakehurst.wiremock.extension.ResponseTransformer;
import com.github.tomakehurst.wiremock.http.HttpHeader;
import com.github.tomakehurst.wiremock.http.HttpHeaders;
import com.github.tomakehurst.wiremock.http.Request;
import com.github.tomakehurst.wiremock.http.Response;

public class ConnectionCloseExtension extends ResponseTransformer {
  @Override
  public Response transform(Request request, Response response, FileSource files, Parameters parameters) {
    return Response.Builder
        .like(response)
        .headers(HttpHeaders.copyOf(response.getHeaders())
            .plus(new HttpHeader("Connection", "Close")))
        .build();
  }

  @Override
  public String getName() {
    return "ConnectionCloseExtension";
  }
}

Step 2: set extension class in wireMockServer like below,

final WireMockServer wireMockServer = new WireMockServer(options()
                .extensions(ConnectionCloseExtension.class)
                .port(httpPort));

For Ubuntu 14.04

sudo apt-get install python-lxml

worked for me.

The static keyword can be used in several different ways in Java and in almost all cases it is a modifier which means the thing it is modifying is usable without an enclosing object instance.

Java is an object oriented language and by default most code that you write requires an instance of the object to be used.

public class SomeObject {
    public int someField;
    public void someMethod() { };
    public Class SomeInnerClass { };
}

In order to use someField, someMethod, or SomeInnerClass I have to first create an instance of SomeObject.

public class SomeOtherObject {
    public void doSomeStuff() {
        SomeObject anInstance = new SomeObject();
        anInstance.someField = 7;
        anInstance.someMethod();
        //Non-static inner classes are usually not created outside of the
        //class instance so you don't normally see this syntax
        SomeInnerClass blah = anInstance.new SomeInnerClass();
    }
}

If I declare those things static then they do not require an enclosing instance.

public class SomeObjectWithStaticStuff {
    public static int someField;
    public static void someMethod() { };
    public static Class SomeInnerClass { };
}

public class SomeOtherObject {
    public void doSomeStuff() {
        SomeObjectWithStaticStuff.someField = 7;
        SomeObjectWithStaticStuff.someMethod();
        SomeObjectWithStaticStuff.SomeInnerClass blah = new SomeObjectWithStaticStuff.SomeInnerClass();
        //Or you can also do this if your imports are correct
        SomeInnerClass blah2 = new SomeInnerClass();
    }
}

Declaring something static has several implications.

First, there can only ever one value of a static field throughout your entire application.

public class SomeOtherObject {
    public void doSomeStuff() {
        //Two objects, two different values
        SomeObject instanceOne = new SomeObject();
        SomeObject instanceTwo = new SomeObject();
        instanceOne.someField = 7;
        instanceTwo.someField = 10;
        //Static object, only ever one value
        SomeObjectWithStaticStuff.someField = 7;
        SomeObjectWithStaticStuff.someField = 10; //Redefines the above set
    }
}

The second issue is that static methods and inner classes cannot access fields in the enclosing object (since there isn't one).

public class SomeObjectWithStaticStuff {
    private int nonStaticField;
    private void nonStaticMethod() { };

    public static void someStaticMethod() {
        nonStaticField = 7; //Not allowed
        this.nonStaticField = 7; //Not allowed, can never use *this* in static
        nonStaticMethod(); //Not allowed
        super.someSuperMethod(); //Not allowed, can never use *super* in static
    }

    public static class SomeStaticInnerClass {

        public void doStuff() {
            someStaticField = 7; //Not allowed
            nonStaticMethod(); //Not allowed
            someStaticMethod(); //This is ok
        }

    }
}

The static keyword can also be applied to inner interfaces, annotations, and enums.

public class SomeObject {
    public static interface SomeInterface { };
    public static @interface SomeAnnotation { };
    public static enum SomeEnum { };
}

In all of these cases the keyword is redundant and has no effect. Interfaces, annotations, and enums are static by default because they never have a relationship to an inner class.

This just describes what they keyword does. It does not describe whether the use of the keyword is a bad idea or not. That can be covered in more detail in other questions such as Is using a lot of static methods a bad thing?

There are also a few less common uses of the keyword static. There are static imports which allow you to use static types (including interfaces, annotations, and enums not redundantly marked static) unqualified.

//SomeStaticThing.java
public class SomeStaticThing {
    public static int StaticCounterOne = 0;
}

//SomeOtherStaticThing.java
public class SomeOtherStaticThing {
    public static int StaticCounterTwo = 0;
}

//SomeOtherClass.java
import static some.package.SomeStaticThing.*;
import some.package.SomeOtherStaticThing.*;

public class SomeOtherClass {
    public void doStuff() {
        StaticCounterOne++; //Ok
        StaticCounterTwo++; //Not ok
        SomeOtherStaticThing.StaticCounterTwo++; //Ok
    }
}

Lastly, there are static initializers which are blocks of code that are run when the class is first loaded (which is usually just before a class is instantiated for the first time in an application) and (like static methods) cannot access non-static fields or methods.

public class SomeObject {

    private static int x;

    static {
        x = 7;
    }
}

The circumflex inside the square brackets means all characters except the subsequent range. You want a circumflex outside of square brackets.

Here is the solution for Rest API

class Program
{
    static void Main(string[] args)
    {
        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");
        BaseResponse response = new BaseResponse();
        BaseResponse response = clientbase.GetCallV2Async("Candidate").Result;
    }


    public async Task<BaseResponse> GetCallAsync(string endpoint)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(endpoint + "/").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            else
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            return baseresponse;
        }
        catch (Exception ex)
        {
            baseresponse.StatusCode = 0;
            baseresponse.ResponseMessage = (ex.Message ?? ex.InnerException.ToString());
        }
        return baseresponse;
    }
}


public class BaseResponse
{
    public int StatusCode { get; set; }
    public string ResponseMessage { get; set; }
}

public class BaseClient
{
    readonly HttpClient client;
    readonly BaseResponse baseresponse;

    public BaseClient(string baseAddress, string username, string password)
    {
        HttpClientHandler handler = new HttpClientHandler()
        {
            Proxy = new WebProxy("http://127.0.0.1:8888"),
            UseProxy = false,
        };

        client = new HttpClient(handler);
        client.BaseAddress = new Uri(baseAddress);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var byteArray = Encoding.ASCII.GetBytes(username + ":" + password);

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

        baseresponse = new BaseResponse();

    }
}

SELECT DISTINCT a,b,c FROM t

is roughly equivalent to:

SELECT a,b,c FROM t GROUP BY a,b,c

It's a good idea to get used to the GROUP BY syntax, as it's more powerful.

For your query, I'd do it like this:

UPDATE sales
SET status='ACTIVE'
WHERE id IN
(
    SELECT id
    FROM sales S
    INNER JOIN
    (
        SELECT saleprice, saledate
        FROM sales
        GROUP BY saleprice, saledate
        HAVING COUNT(*) = 1 
    ) T
    ON S.saleprice=T.saleprice AND s.saledate=T.saledate
 )

That's because the json you're getting is an array of your RootObject class, rather than a single instance, change your DeserialiseObject<RootObject> to be something like DeserialiseObject<RootObject[]> (un-tested).

You'll then have to either change your method to return a collection of RootObject or do some further processing on the deserialised object to return a single instance.

If you look at a formatted version of the response you provided:

[
   {
      "id":3636,
      "is_default":true,
      "name":"Unit",
      "quantity":1,
      "stock":"100000.00",
      "unit_cost":"0"
   },
   {
      "id":4592,
      "is_default":false,
      "name":"Bundle",
      "quantity":5,
      "stock":"100000.00",
      "unit_cost":"0"
   }
]

You can see two instances in there.

Since the return statement terminates the execution of the current function, the two forms are equivalent (although the second one is arguably more readable than the first).

The efficiency of both forms is comparable, the underlying machine code has to perform a jump if the if condition is false anyway.

Note that Python supports a syntax that allows you to use only one return statement in your case:

return A+1 if A > B else A-1

On recent Ubuntu (20.10) sudo apt-get install golang works fine; it will install version 1.14.

You missed the closing tag for the input fields, and you can choose any one of the events, ex: onload, onclick etc.

(a) Onload event:

<script type="text/javascript">
$(document).ready(function(){
     $('#frm1').submit();
});
</script>

(b) Onclick Event:

<form name="frm1" id="frm1" action="../somePage" method="post">
    Please Waite... 
    <input type="hidden" name="uname" id="uname" value=<?php echo $uname;?> />
    <input type="hidden" name="price" id="price" value=<?php echo $price;?> />
    <input type="text" name="submit" id="submit" value="submit">
</form>
<script type="text/javascript">
$('#submit').click(function(){
     $('#frm1').submit();
});
</script>

While it's possible to call open(filename, 'rb') and check through the binary image headers for the dimensions, it seems much more useful to install PIL and spend your time writing great new software! You gain greater file format support and the reliability that comes from widespread usage. From the PIL documentation, it appears that the code you would need to complete your task would be:

from PIL import Image
im = Image.open('filename.png')
print 'width: %d - height: %d' % im.size # returns (width, height) tuple

As for writing code yourself, I'm not aware of a module in the Python standard library that will do what you want. You'll have to open() the image in binary mode and start decoding it yourself. You can read about the formats at:

• PNG file format documentation
• Notes on the JPEG file format headers

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

You are trying to insert data that is larger than allowed for the column logo.

Use following data types as per your need

TINYBLOB   :     maximum length of 255 bytes  
BLOB       :     maximum length of 65,535 bytes  
MEDIUMBLOB :     maximum length of 16,777,215 bytes  
LONGBLOB   :     maximum length of 4,294,967,295 bytes  

Use LONGBLOB to avoid this exception.

Many SQL databases allow a table to contain a subtable as a component. The usual method is to allow the domain of one of the columns to be a table. This is in addition to using some convention like CSV to encode the substructure in ways unknown to the DBMS.

When Ed Codd was developing the relational model in 1969-1970, he specifically defined a normal form that would disallow this kind of nesting of tables. Normal form was later called First Normal Form. He then went on to show that for every database, there is a database in first normal form that expresses the same information.

Why bother with this? Well, databases in first normal form permit keyed access to all data. If you provide a table name, a key value into that table, and a column name, the database will contain at most one cell containing one item of data.

If you allow a cell to contain a list or a table or any other collection, now you can't provide keyed access to the sub items, without completely reworking the idea of a key.

Keyed access to all data is fundamental to the relational model. Without this concept, the model isn't relational. As to why the relational model is a good idea, and what might be the limitations of that good idea, you have to look at the 50 years worth of accumulated experience with the relational model.

The most upvoted answer, from Kris Selbekk, it is totally right. It is important to highlight though that it takes a functional approach, you will be looping through the this.props.comments array twice, the second time(looping) it will most probable skip a few elements that where filtered, but in case no comment was filtered you will loop through the whole array twice. If performance is not a concern in you project that is totally fine. In case performance is important a guard clause would be more appropriated as you would loop the array only once:

return this.props.comments.map((comment) => {
  if (!comment.hasComments) return null; 

  return (
    <div key={comment.id}>         
      <CommentItem className="MainComment"/>
        {this.props.comments.map(commentReply => {             
          if (commentReply.replyTo !== comment.id) return null;

          return <CommentItem className="SubComment"/>
        })} 
    </div>          
  ) 
}

The main reason I'm pointing this out is because as a Junior Developer I did a lot of those mistakes(like looping the same array multiple times), so I thought i was worth mention it here.

PS: I would refactor your react component even more, as I'm not in favour of heavy logic in the html part of a JSX, but that is out of the topic of this question.

In SQL, this problem could be solved by several methods:

select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)

or join and then unpivot (possible in SQL server)

select
    df1.user_id,
    c.rating
from df1
    inner join df2 on df2.user_i = df1.user_id
    outer apply (
        select df1.rating union all
        select df2.rating
    ) as c

Second one could be written in pandas with something like:

>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
   user_id  rating
0        3      20
0        3      30

A more general answer would be to import java.util.Date, then when you need to set a timestamp equal to the current date, simply set it equal to new Date().

SELECT 
   AcId, AcName, PldepPer, RepId, CustCatg, HardCode, BlockCust, CrPeriod, CrLimit, 
   BillLimit, Mode, PNotes, gtab82.memno 
FROM
   VCustomer AS v1
INNER JOIN   
   gtab82 ON gtab82.memacid = v1.AcId 
WHERE (AcGrCode = '204' OR CreDebt = 'True') 
AND Masked = 'false'
ORDER BY AcName

You typically only use an alias for a table name when you need to prefix a column with the table name due to duplicate column names in the joined tables and the table name is long or when the table is joined to itself. In your case you use an alias for VCustomer but only use it in the ON clause for uncertain reasons. You may want to review that aspect of your code.

You can use the watch mode to detect changes:

Do everything at atomic level. So first check if watch method itself is getting called or not by consoling something inside. Once it has been established that watch is getting called, smash it out with your business logic.

watch: { 
  myProp: function() {
   console.log('Prop changed')
  }
}

See this Codepen link for faster and easy way of checking an element if it has a specific class using vanilla JavaScript~!

hasClass (Vanilla JS)

function hasClass(element, cls) {
    return (' ' + element.className + ' ').indexOf(' ' + cls + ' ') > -1;
}

Assuming that your button is in a form, you are not preventing the default behaviour of the button click from happening i.e. Your AJAX call is made in addition to the form submission; what you're very likely seeing is one of

1. the form submission happens faster than the AJAX call returns
2. the form submission causes the browser to abort the AJAX request and continues with submitting the form.

So you should prevent the default behaviour of the button click

$('#btnSave').click(function (e) {

    // prevent the default event behaviour    
    e.preventDefault();

    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {

            // perform your save call here

            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

All other answers must work, but using your same syntax (and understanding why the error)

SELECT * FROM MyParts LEFT JOIN MyPrice ON MyParts.Partid = MyPrice.Partid WHERE 
MyPart.PriceDate = (SELECT MAX(MyPrice2.PriceDate) FROM MyPrice as MyPrice2 
WHERE MyPrice2.Partid =  MyParts.Partid)

There is a possibility that your IP/host are blocked by the remote host, especially if it thinks you are hitting it too hard.

when u pass any array to some function. u are just passing it's starting address, so for it to work u have to pass it size also for it to work properly. it's the same reason why we pass argc with argv[] in command line arguement.

If you were using JGraph, you should give a try to JGraphT which is designed for algorithms. One of its features is visualization using the JGraph library. It's still developed, but pretty stable. I analyzed the complexity of JGraphT algorithms some time ago. Some of them aren't the quickest, but if you're going to implement them on your own and need to display your graph, then it might be the best choice. I really liked using its API, when I quickly had to write an app that was working on graph and displaying it later.

Use System.arraycopy.

using a function:

function run_command ($command)
{
    invoke-expression "$command *>$null"
    return $_
}

if (!(run_command "dir *.txt"))
{
    if (!(run_command "dir *.doc"))
    {
        run_command "dir *.*"
    }
}

or if you like one-liners:

function run_command ($command) { invoke-expression "$command  "|out-null; return $_ }

if (!(run_command "dir *.txt")) { if (!(run_command "dir *.doc")) { run_command "dir *.*" } }

There's a very simple answer: it's defensive programming. You know that the uses of std::size_t, std::cout, etc., could be made a little easier with using namespace std; - I hope you don't need to be convinced that such a directive has no place in a header! Within a translation unit, however, you might be tempted...

The types, classes, etc., that are part of the std namespace increase with each C++ revision. There are too many potential ambiguities if you relax the std:: qualifier. It is entirely reasonable to relax the qualifier for names within std that you will be using frequently, e.g., using std::fprintf;, or more probably, something like: using std::size_t; - but unless these are already well-understood parts of the language (or specifically, the std wrapping of the C library), just use the qualifier.

When you can use typedef, combined with auto and decltype inferencing, there's really nothing to be gained from a readability / maintainability perspective.

You might use Form tag with action attribute to submit the mailto.

Here is an example:

<form method="post" action="mailto:[email protected]" >
<input type="submit" value="Send Email" /> 
</form>

If you want to switch the jdk on a regular basis (or update to a new one once it is released), it's very conveniant to use sdkman.

You can additional tools like maven with sdkman, too.

DECLARE @porcentaje FLOAT

SET @porcentaje = (CONVERT(DECIMAL,ABS(8700)) * 100) / CONVERT(DECIMAL,ABS(37020))

SELECT @porcentaje

Do not make the situation complex. Use ID if they are available.

driver.get("http://www.rediff.com");
WebElement sign = driver.findElement(By.linkText("Sign in"));
sign.click();
WebElement email_id= driver.findElement(By.id("c_uname"));
email_id.sendKeys("hi");

• Binary trees are used in Huffman coding, which are used as a compression code.
• Binary trees are used in Binary search trees, which are useful for maintaining records of data without much extra space.

If you're interested in seeing which specific headers a remote client is sending to your server, and you can cause the request to run a CGI script, then the simplest solution is to have your server script dump the environment variables into a file somewhere.

e.g. run the shell command "env > /tmp/headers" from within your script

Then, look for the environment variables that start with HTTP_...

You will see lines like:

HTTP_ACCEPT=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
HTTP_ACCEPT_ENCODING=gzip, deflate
HTTP_ACCEPT_LANGUAGE=en-US,en;q=0.5
HTTP_CACHE_CONTROL=max-age=0

Each of those represents a request header.

Note that the header names are modified from the actual request. For example, "Accept-Language" becomes "HTTP_ACCEPT_LANGUAGE", and so on.

I had this error, I looked into a log file C:\...\mysql\data\VM-IIS-Server.err and found this

2016-06-07 17:56:07 160c  InnoDB: Error: unable to create temporary file; errno: 2

The first line says "unable to create temporary file", it sounds like "insufficient privileges", first I tried to give access to mysql folder for my current user - no effect, then after some wandering around I came up to control panel->Administration->Services->Right Clicked MysqlService->Properties->Log On, switched to "This account", entered my username/password, clicked OK, and it woked!

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

How does spring know which polymorphic type to use.

As long as there is only a single implementation of the interface and that implementation is annotated with @Component with Spring's component scan enabled, Spring framework can find out the (interface, implementation) pair. If component scan is not enabled, then you have to define the bean explicitly in your application-config.xml (or equivalent spring configuration file).

Do I need @Qualifier or @Resource?

Once you have more than one implementation, then you need to qualify each of them and during auto-wiring, you would need to use the @Qualifier annotation to inject the right implementation, along with @Autowired annotation. If you are using @Resource (J2EE semantics), then you should specify the bean name using the name attribute of this annotation.

Why do we autowire the interface and not the implemented class?

Firstly, it is always a good practice to code to interfaces in general. Secondly, in case of spring, you can inject any implementation at runtime. A typical use case is to inject mock implementation during testing stage.

interface IA
{
  public void someFunction();
}


class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Your bean configuration should look like this:

<bean id="b" class="B" />
<bean id="c" class="C" />
<bean id="runner" class="MyRunner" />

Alternatively, if you enabled component scan on the package where these are present, then you should qualify each class with @Component as follows:

interface IA
{
  public void someFunction();
}

@Component(value="b")
class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


@Component(value="c")
class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

@Component    
class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Then worker in MyRunner will be injected with an instance of type B.

This is realy helpfull

SET search_path TO schema,public;

I digged this issues more, and found out about how to set this "search_path" by defoult for a new user in current database.

Open DataBase Properties then open Sheet "Variables" and simply add this variable for your user with actual value.

So now your user will get this schema_name by defoult and you could use tableName without schemaName.

try using

@record.assign_attributes({ ... })
@record.save(validate: false)

works for me

Between those two syntaxes, you should really choose the one you prefer :-)

Personally, I would go with your second solution in such a case (Variable interpolation), which I find easier to both write and read.

The result will be the same; and even if there are performance implications, those won't matter ¹.

As a sidenote, so my answer is a bit more complete: the day you'll want to do something like this:

echo "Welcome $names!";

PHP will interpret your code as if you were trying to use the $names variable -- which doesn't exist. - note that it will only work if you use "" not '' for your string.

That day, you'll need to use {}:

echo "Welcome {$name}s!"

No need to fallback to concatenations.

Also note that your first syntax:

echo "Welcome ".$name."!";

Could probably be optimized, avoiding concatenations, using:

echo "Welcome ", $name, "!";

(But, as I said earlier, this doesn't matter much...)

_{1 - Unless you are doing hundreds of thousands of concatenations vs interpolations -- and it's probably not quite the case.}

using System.IO;
...
foreach (string file in Directory.EnumerateFiles(folderPath, "*.xml"))
{
    string contents = File.ReadAllText(file);
}

Note the above uses a .NET 4.0 feature; in previous versions replace EnumerateFiles with GetFiles). Also, replace File.ReadAllText with your preferred way of reading xml files - perhaps XDocument, XmlDocument or an XmlReader.

type NUL > EmptyFile.txt

After reading the previous two posts, this blend of the two is what I came up with. It seems a little cleaner. There is no need to worry about redirecting the "1 file(s) copied." message to NUL, like the previous post does, and it looks nice next to the ECHO OutputLineFromLoop >> Emptyfile.txt that will usually follow in a batch file.

asarray(x) is like array(x, copy=False)

Use asarray(x) when you want to ensure that x will be an array before any other operations are done. If x is already an array then no copy would be done. It would not cause a redundant performance hit.

Here is an example of a function that ensure x is converted into an array first.

def mysum(x):
    return np.asarray(x).sum()

weightMatrix = [{'A':0,'C':0,'G':0,'T':0} for k in range(motifWidth)]

netstat -nlp should tell you the PID of what's listening on which port.

Sorry, you can't view or download this file at this time is an error message that you may get when you try to download files on Google Drive.

Bandwidth limits

Limit                          Per hour            Per day
Download via web client        750 MB              1250 MB
Upload via web client          300 MB              500 MB

The explanation for the error message is simple: while users are free to share files publicly, or with a large number of users, quotas are in effect that limit availability.

If too many users view or download a file, it may be locked for a 24 hour period before the quota is reset. The period that a file is locked may be shorter according to Google.

If a file is particularly popular, it may take days or even longer before you manage to download it to your computer or place it on your Drive storage.

It could be a solution:

1. Locate the "uc" part of the address, and replace it with "open", so that the beginning of the URL reads * https:// drive.google.com/open?*

2. Load the address again once you have replaced uc with open in the address.

3. This loads a new screen with controls at the top.

4. Click on the "add to my drive" icon at the top right.

5. Click on "add to my drive" again to open your Google Drive storage in a new tab in the browser.

6. You should see the locked file on your drive now.

7. Select it with a right-click, and then the "make a copy" option from the menu.

   8.Select the copy of the file with a right-click, and there download to download the file to your local system.

Basically, what this does is create a copy of the file on your own Drive account. Since you are the owner of the copied file, you may download it to your local system this way.

Please note that this works only if you are signed in to a Google Account. Also note that you are the owner of the copied file and will be held responsible for policy violations or other issues linked to the file.

Another option is: Any public folder in Drive can host files and provide direct links to the files.

How to create the hosting URL: https:// googledrive.com/host/FolderID (your id file)

This will provide a folder that will give direct links to files inside the folder. Note: hosting view will not display files created in Google Docs.

My solution:

I had the same problem, so I made a JSON file in Google Drive but the URL file (.mp3) is in Dropbox. It is working fantastic even though I have 40,000 active user. I used this solution because I did not have time to search too much! I wrote you the Dropbox Limits anyway but I did not get problems with it

Traffic limits DROPBOX

Links and file requests are automatically banned if they generate unusually large amounts of traffic.

Dropbox Basic (free) accounts:

20 GB per day: The total amount of traffic that all of your links and file requests combined can generate without getting banned 100,000 downloads per day: The total number of downloads that all of your links combined can generate

Dropbox Plus and Business accounts: About 200 GB per day: The total amount of traffic that all of your links and file requests combined can generate without getting banned There's no daily limit to the number of downloads that your links can generate If your account hits our limit, we'll send a message to the email address registered to your account. Your links will be temporarily disabled, and anyone who tries to access them will see an error page instead of your files.

P.S. If you need more information about my files and how did it and How to make the URL File from Dropbox, I hope help to the people is reading this! (I posted it before but Someone deleted my last post)!

I have found a solution by myself. I use the PDANet tool to find the driver automatically.

You can also write this in mysql -

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date < DATE_ADD(NOW(), INTERVAL -1 MONTH);

FIXED

Math.floor() will work, but it's very slow compared to using a bitwise OR operation:

var rounded = 34.923 | 0;
alert( rounded );
//alerts "34"

EDIT Math.floor() is not slower than using the | operator. Thanks to Jason S for checking my work.

Here's the code I used to test:

var a = [];
var time = new Date().getTime();
for( i = 0; i < 100000; i++ ) {
    //a.push( Math.random() * 100000  | 0 );
    a.push( Math.floor( Math.random() * 100000 ) );
}
var elapsed = new Date().getTime() - time;
alert( "elapsed time: " + elapsed );

Article on Programming.Guide: Switch on enum

enum MyEnum { CONST_ONE, CONST_TWO }

class Test {
        public static void main(String[] args) {
            MyEnum e = MyEnum.CONST_ONE;

            switch (e) {
                case CONST_ONE: System.out.println(1); break;
                case CONST_TWO: System.out.println(2); break;
            }
        }
    }

Switches for strings are implemented in Java 7.

Also, you can use shelljs plugin. It's easy and it's cross-platform.

Install command:

npm install [-g] shelljs

What is shellJS

ShellJS is a portable (Windows/Linux/OS X) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!

An example of how it works:

var shell = require('shelljs');

if (!shell.which('git')) {
  shell.echo('Sorry, this script requires git');
  shell.exit(1);
}

// Copy files to release dir
shell.rm('-rf', 'out/Release');
shell.cp('-R', 'stuff/', 'out/Release');

// Replace macros in each .js file
shell.cd('lib');
shell.ls('*.js').forEach(function (file) {
  shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
  shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
  shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
});
shell.cd('..');

// Run external tool synchronously
if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
  shell.echo('Error: Git commit failed');
  shell.exit(1);
}

Also, you can use from the command line:

$ shx mkdir -p foo
$ shx touch foo/bar.txt
$ shx rm -rf foo

Usually the msb file not found problems are the result of an environment setting problem, but in your case I'm a little suspicious of the installation (I've never used the apt-get + configure method).

To check the sanity of the installation:

• ORACLE_HOME should be set to a directory path one level above the bin directory where sqlplus executable is found.
• There should some .msb files under $ORACLE_HOME/sqlplus/mesg
• There should be hundreds (not sure of the number with XE) of .msb files under $ORACLE_HOME (try find $ORACLE_HOME -name "*.msb" -print to show them)
• Your PATH should include $ORACLE_HOME/bin.
• All files under ORACLE_HOME should be owned by user:oracle group:dba.

Another option for Perl would be Web::Scraper which is based on Ruby's Scrapi. In a nutshell, with nice and concise syntax, you can get a robust scraper directly into data structures.

Let us see the difference between the two HTTP authentication using Wireshark (Tool to analyse packets sent or received) .

1. Http Basic Authentication

As soon as the client types in the correct username:password,as requested by the Web-server, the Web-Server checks in the Database if the credentials are correct and gives the access to the resource .

Here is how the packets are sent and received :

In the first packet the Client fill the credentials using the POST method at the resource - lab/webapp/basicauth .In return the server replies back with http response code 200 ok ,i.e, the username:password were correct .

Now , In the Authorization header it shows that it is Basic Authorization followed by some random string .This String is the encoded (Base64) version of the credentials admin:aadd (including colon ) .

2 . Http Digest Authentication(rfc 2069)

So far we have seen that the Basic Authentication sends username:password in plaintext over the network .But the Digest Auth sends a HASH of the Password using Hash algorithm.

Here are packets showing the requests made by the client and response from the server .

As soon as the client types the credentials requested by the server , the Password is converted to a response using an algorithm and then is sent to the server , If the server Database has same response as given by the client the server gives the access to the resource , otherwise a 401 error .

In the above Authorization , the response string is calculated using the values of Username,Realm,Password,http-method,URI and Nonce as shown in the image :

(colons are included)

Hence , we can see that the Digest Authentication is more Secure as it involve Hashing (MD5 encryption) , So the packet sniffer tools cannot sniff the Password although in Basic Auth the exact Password was shown on Wireshark.

For enterprise applications it should be noted that you should not be handling https in your code. It should be auto upgraded via IIS or nginx. The app shouldn't know about what protocols are used.

PS> $a = "-----start-------Hello World------end-------"
PS> $a.substring(17, 11)
         or
PS> $a.Substring($a.IndexOf('H'), 11)

$a.Substring(argument1, argument2) --> Here argument1 = Starting position of the desired alphabet and argument2 = Length of the substring you want as output.

Here 17 is the index of the alphabet 'H' and since we want to Print till Hello World, we provide 11 as the second argument

Simple! Add at the end of dockerfile:

ENTRYPOINT service mysql start && /bin/bash

Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:

ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);

In addition to above answers, another way of doing it is $_SERVER['PHP_SELF'] or simply using an empty string is to use __DIR__.
OR
If you're on a lower PHP version (<5.3), a more common alternative is to use dirname(__FILE__)
Both returns the folder name of the file in context.

EDIT
As Boann pointed out that this returns the on-disk location of the file. WHich you would not ideally expose as a url. In that case dirname($_SERVER['PHP_SELF']) can return the folder name of the file in context.

In Jan 2013, Microsoft announced that they are adding full Git support into all their ALM products. They have published a plugin for Visual Studio 2012 that adds Git source control integration.

Alternatively, there is a project called Git Extensions that includes add-ins for Visual Studio 2005, 2008, 2010 and 2012, as well as Windows Explorer integration. It's regularly updated and having used it on a couple of projects, I've found it very useful.

Another option is Git Source Control Provider.

I made a Medium article for this.

MVVM

1. View ? ViewModel ? Model

   • The view has a reference to the ViewModel but not vice versa.
   • The ViewModel has a reference to the Model but not vice versa.
   • The View has no reference to the Model and vice versa.

2. If you are using a controller, it can have a reference to Views and ViewModels, though a Controller is not always necessary as demonstrated in SwiftUI.

3. Data Binding: we create listeners for ViewModel Properties.

class CustomView: UIView {
  var viewModel = MyViewModel {
    didSet {
      self.color = viewModel.color
    }
  }

  convenience init(viewModel: MyViewModel) {
    self.viewModel = viewModel
  }
}


struct MyViewModel {
   var viewColor: UIColor {
      didSet {
         colorChanged?() // This is where the binding magic happens.
      }
   }

   var colorChanged: ((UIColor) -> Void)?
}


class MyViewController: UIViewController {

   let myViewModel = MyViewModel(viewColor: .green)
   let customView: CustomView!

   override func viewDidLoad() {
      super.viewDidLoad()

      // This is where the binder is assigned.
      myViewModel.colorChanged = { [weak self] color in 
        print("wow the color changed")
      }
      customView = CustomView(viewModel: myViewModel)
      self.view = customView
   }
}

differences in setup

1. Business logic is held in the controller for MVC and the ViewModels for MVVM.
2. Events are passed directly from the View to the controller in MVC while events are passed from the View to the ViewModel to the Controller (if there is one) for MVVM.

Common features

1. Both MVVM and MVC do not allow the View to send messages directly to the Model/s.
2. Both have models.
3. Both have views.

Advantages of MVVM

1. Because the ViewModels hold business logic, they are smaller concrete objects making them easy to unit tests. On the other hand, in MVC, the business logic is in the ViewController. How can you trust that a unit test of a view controller is comprehensively safe without testing all the methods and listeners simultaneously? You can't wholly trust the unit test results.
2. In MVVM, because business logic is siphoned out of the Controller into atomic ViewModel units, the size of the ViewController shrinks and this makes the ViewController code more legible.

Advantages of MVC

1. Providing business logic within the controller reduces the need for branching and therefore statements are more likely to run on the cache which is more performant over encapsulating business logic into ViewModels.
2. Providing business logic in one place can accelerate the development process for simple applications, where tests are not required. I don't know when tests are not required.
3. Providing business logic in the ViewController is easier to think about for new developers.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText edit = (EditText)findViewById(R.id.editText);          
        final RadioButton rb1 = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rb2 = (RadioButton) findViewById(R.id.radioFT);                       
        if(rb1.isChecked()){    
            edit.setVisibility(View.VISIBLE);              
        }
        else if(rb2.isChecked()){               
            edit.setVisibility(View.INVISIBLE);
        }
}

AJAX is a way of sending information between browser and server without refreshing page. It can be done with or without library like jQuery.

It is easier with the library.

Here is a list of JavaScript libraries/frameworks commonly used in AJAX development.

Try this:
#ifdef _WIN64
// 64 bit code
#elif _WIN32
// 32 bit code
#else
   if(sizeof(void*)==4)

       // 32 bit code
   else 

       // 64 bit code   
#endif

Try this, it should solve your issue

1. In your config.php, add www pre in your domain.com. For example:

   HTTP define('HTTP_SERVER', 'http://domain name with www/');
   HTTPS define('HTTPS_SERVER', 'http://domain name with www/');
   

2. Add this to your .htaccess file

   RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule ^(.*)$ $1 [R=200,L]
   

I agree with Vladimir. The administrators in my company would definitely not appreciate it if I even suggested such a course.

Further, creating an SQL script in stead of blindly trusting Hibernate gives you the opportunity to remove fields which are no longer in use. Hibernate does not do that.

And I find comparing the production schema with the new schema gives you even better insight to wat you changed in the data model. You know, of course, because you made it, but now you see all the changes in one go. Even the ones which make you go like "What the heck?!".

There are tools which can make a schema delta for you, so it isn't even hard work. And then you know exactly what's going to happen.

jQuery Core doesn't have anything special, but you can read on jQuery Mobile Events page about different touch events, which also work on other than iOS devices as well.

They are:

• tap
• taphold
• swipe
• swipeleft
• swiperight

Notice also, that during scroll events (based on touch on mobile devices) iOS devices freezes DOM manipulation while scrolling.

Use the time package to work with time information in Go.

Time instants can be compared using the Before, After, and Equal methods. The Sub method subtracts two instants, producing a Duration. The Add method adds a Time and a Duration, producing a Time.

Play example:

package main

import (
    "fmt"
    "time"
)

func inTimeSpan(start, end, check time.Time) bool {
    return check.After(start) && check.Before(end)
}

func main() {
    start, _ := time.Parse(time.RFC822, "01 Jan 15 10:00 UTC")
    end, _ := time.Parse(time.RFC822, "01 Jan 16 10:00 UTC")

    in, _ := time.Parse(time.RFC822, "01 Jan 15 20:00 UTC")
    out, _ := time.Parse(time.RFC822, "01 Jan 17 10:00 UTC")

    if inTimeSpan(start, end, in) {
        fmt.Println(in, "is between", start, "and", end, ".")
    }

    if !inTimeSpan(start, end, out) {
        fmt.Println(out, "is not between", start, "and", end, ".")
    }
}

Use String#toLowerCase() or String#equalsIgnoreCase() methods

Some examples:

    String abc    = "Abc".toLowerCase();
    boolean isAbc = "Abc".equalsIgnoreCase("ABC");

Have you tried adding lines below to your web.xml?

<context-param>
   <param-name>com.sun.faces.enableRestoreView11Compatibility</param-name>
   <param-value>true</param-value>
</context-param>

I found this to be very effective when I encountered this issue.

perldoc perlvar is the first place to check for any special-named Perl variable info.

Quoting:

@_: Within a subroutine the array @_ contains the parameters passed to that subroutine.

More details can be found in perldoc perlsub (Perl subroutines) linked from the perlvar:

Any arguments passed in show up in the array @_ .

Therefore, if you called a function with two arguments, those would be stored in $_[0] and $_[1].

The array @_ is a local array, but its elements are aliases for the actual scalar parameters. In particular, if an element $_[0] is updated, the corresponding argument is updated (or an error occurs if it is not updatable).

If an argument is an array or hash element which did not exist when the function was called, that element is created only when (and if) it is modified or a reference to it is taken. (Some earlier versions of Perl created the element whether or not the element was assigned to.) Assigning to the whole array @_ removes that aliasing, and does not update any arguments.

To summarize the other answers, for general use:

Multi-line if...then statement

if [ foo ]; then
    a; b
elif [ bar ]; then
    c; d
else
    e; f
fi

Single-line version

if [ foo ]; then a && b; elif [ bar ]; c && d; else e && f; fi

Using the OR operator

( foo && a && b ) || ( bar && c && d ) || e && f;

Notes

Remember that the AND and OR operators evaluate whether or not the result code of the previous operation was equal to true/success (0). So if a custom function returns something else (or nothing at all), you may run into problems with the AND/OR shorthand. In such cases, you may want to replace something like ( a && b ) with ( [ a == 'EXPECTEDRESULT' ] && b ), etc.

Also note that ( and [ are technically commands, so whitespace is required around them.

Instead of a group of && statements like then a && b; else, you could also run statements in a subshell like then $( a; b ); else, though this is less efficient. The same is true for doing something like result1=$( foo; a; b ); result2=$( bar; c; d ); [ "$result1" -o "$result2" ] instead of ( foo && a && b ) || ( bar && c && d ). Though at that point you'd be getting more into less-compact, multi-line stuff anyway.

hey this is the best solution I ever experienced.. this is CSS3

use following property to your div or anywhere you wanna put border trasparent

e.g.

div_class { 
 border: 10px solid #999;
 background-clip: padding-box; /* Firefox 4+, Opera, for IE9+, Chrome */
}

this will work..

If you don't have the .PBO file:

C#

public int GetLineNumber(Exception ex)
{
    var lineNumber = 0;
    const string lineSearch = ":line ";
    var index = ex.StackTrace.LastIndexOf(lineSearch);
    if (index != -1)
    {
        var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
        if (int.TryParse(lineNumberText, out lineNumber))
        {
        }
    }
    return lineNumber;
}

Vb.net

Public Function GetLineNumber(ByVal ex As Exception)
    Dim lineNumber As Int32 = 0
    Const lineSearch As String = ":line "
    Dim index = ex.StackTrace.LastIndexOf(lineSearch)
    If index <> -1 Then
        Dim lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length)
        If Int32.TryParse(lineNumberText, lineNumber) Then
        End If
    End If
    Return lineNumber
End Function

Or as an extentions on the Exception class

public static class MyExtensions
{
    public static int LineNumber(this Exception ex)
    {
        var lineNumber = 0;
        const string lineSearch = ":line ";
        var index = ex.StackTrace.LastIndexOf(lineSearch);
        if (index != -1)
        {
            var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
            if (int.TryParse(lineNumberText, out lineNumber))
            {
            }
        }
        return lineNumber;
    }
}   

When you correct the measurements - as mentioned above: Any and Exists, and adding average - we'll get following output:

Executing search Exists() 1000 times ... 
Average Exists(): 35566,023
Fastest Exists() execution: 32226 

Executing search Any() 1000 times ... 
Average Any(): 58852,435
Fastest Any() execution: 52269 ticks

Boost.Regex is very good and is slated to become part of the C++0x standard (it's already in TR1).

Personally, I find Boost.Xpressive much nicer to work with. It is a header-only library and it has some nice features such as static regexes (regexes compiled at compile time).

Update: If you're using a C++11 compliant compiler (gcc 4.8 is NOT!), use std::regex unless you have good reason to use something else.

If you want specifically do something when click on close button exactly like you described:

<a href="#" class="btn close_link" data-dismiss="modal">Close</a>

you need to attach an event using css selector:

$(document).on('click', '[data-dismiss="modal"]', function(){what you want to do})

But if you want to do something when modal close, you can use the already wrote tips

Why don't you just use CopyToDataTable

DataTable dt = (DataTable)Session["dtAllOrders"];
DataTable dtSpecificOrders = new DataTable();

DataTable orderRows = dt.Select("CustomerID = 2").CopyToDataTable();

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

sys.tables

Contains all tables. so exec this query to get all tables with details.

SELECT * FROM sys.tables

or simply select Name from sys.tables to get the name of all tables.

SELECT Name From sys.tables

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

Instead of using

response.sendRedirect("/demo.jsp");

Which does a permanent redirect to an absolute URL path,

Rather use RequestDispatcher. Example:

RequestDispatcher dispatcher = request.getRequestDispatcher("demo.jsp");
dispatcher.forward(request, response);

@echo off
cd C:\Program Files (x86)\MySQL\MySQL Workbench 6.0 CE

for %%a in (D:\abc\*.sql) do (
echo %%a
mysql --host=ip --port=3306 --user=uid--password=ped < %%a
)

Step1: above lines copy into note pad save it as bat.

step2: In d drive abc folder in all Sql files in queries executed in sql server.

step3: Give your ip, user id and password.

In Express it's already done for you and you can simply use req.query for that:

var id = req.query.id; // $_GET["id"]

Otherwise, in NodeJS, you can access req.url and the builtin url module to url.parse it manually:

var url = require('url');
var url_parts = url.parse(request.url, true);
var query = url_parts.query;

    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser          
    processData:false, //To avoid making query String instead of JSON
    success: function(resposeJsonObject){
        // Success Message Handler
    }
});

Controller side

@RequestMapping(value = urlPattern , method = RequestMethod.POST)
public @ResponseBody Person save(@RequestBody Person jsonString) {

   Person person=personService.savedata(jsonString);
   return person;

You can't have multiple lines in a text box, you need a textarea. Then it works with \n between the values.

<%@ Application CodeFile="Global.asax.cs" Inherits="ApplicationName.MyApplication" Language="C#" %>

~/Global.asax.cs:

namespace ApplicationName
{
    public partial class MyApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
        }
    }
}

Many answer above are correct but same time convoluted with other aspects of authN/authZ. What actually resolves the exception in question is this line:

services.AddScheme<YourAuthenticationOptions, YourAuthenticationHandler>(YourAuthenticationSchemeName, options =>
    {
        options.YourProperty = yourValue;
    })

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

Make another request based on response.headers.location:

      const request = function(url) {
        lib.get(url, (response) => {
          var body = [];
          if (response.statusCode == 302) {
            body = [];
            request(response.headers.location);
          } else {
            response.on("data", /*...*/);
            response.on("end", /*...*/);
          };
        } ).on("error", /*...*/);
      };
      request(url);

Well after a bit of hacking of Tim Golden's script, I have the following which seems to work quite well:

import os

import win32file
import win32con

path_to_watch = "." # look at the current directory
file_to_watch = "test.txt" # look for changes to a file called test.txt

def ProcessNewData( newData ):
    print "Text added: %s"%newData

# Set up the bits we'll need for output
ACTIONS = {
  1 : "Created",
  2 : "Deleted",
  3 : "Updated",
  4 : "Renamed from something",
  5 : "Renamed to something"
}
FILE_LIST_DIRECTORY = 0x0001
hDir = win32file.CreateFile (
  path_to_watch,
  FILE_LIST_DIRECTORY,
  win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE,
  None,
  win32con.OPEN_EXISTING,
  win32con.FILE_FLAG_BACKUP_SEMANTICS,
  None
)

# Open the file we're interested in
a = open(file_to_watch, "r")

# Throw away any exising log data
a.read()

# Wait for new data and call ProcessNewData for each new chunk that's written
while 1:
  # Wait for a change to occur
  results = win32file.ReadDirectoryChangesW (
    hDir,
    1024,
    False,
    win32con.FILE_NOTIFY_CHANGE_LAST_WRITE,
    None,
    None
  )

  # For each change, check to see if it's updating the file we're interested in
  for action, file in results:
    full_filename = os.path.join (path_to_watch, file)
    #print file, ACTIONS.get (action, "Unknown")
    if file == file_to_watch:
        newText = a.read()
        if newText != "":
            ProcessNewData( newText )

It could probably do with a load more error checking, but for simply watching a log file and doing some processing on it before spitting it out to the screen, this works well.

Thanks everyone for your input - great stuff!

?library

and you will see:

library(package) and require(package) both load the package with name package and put it on the search list. require is designed for use inside other functions; it returns FALSE and gives a warning (rather than an error as library() does by default) if the package does not exist. Both functions check and update the list of currently loaded packages and do not reload a package which is already loaded. (If you want to reload such a package, call detach(unload = TRUE) or unloadNamespace first.) If you want to load a package without putting it on the search list, use requireNamespace.

A solution above using DigestUtils didn't work for me. In my version of Apache commons (the latest one for 2013) there is no such class.

I found another solution here in one blog. It works perfect and doesn't need Apache commons. It looks a little shorter than the code in accepted answer above.

public static String getMd5Hash(String input) {
    try {
        MessageDigest md = MessageDigest.getInstance("MD5");
        byte[] messageDigest = md.digest(input.getBytes());
        BigInteger number = new BigInteger(1, messageDigest);
        String md5 = number.toString(16);

        while (md5.length() < 32)
            md5 = "0" + md5;

        return md5;
    } catch (NoSuchAlgorithmException e) {
        Log.e("MD5", e.getLocalizedMessage());
        return null;
    }
}

You will need these imports:

import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

$(document).ready(function(){ $("input:radio:checked").data("chk",true);

$("input:radio").click(function(){
    $("input[name='"+$(this).attr("name")+"']:radio").not(this).removeData("chk");

    $(this).data("chk",!$(this).data("chk"));

    $(this).prop("checked",$(this).data("chk"));
});

});

This should work in Matlab:

set(gca, 'XAxisLocation', 'origin')

Options are: bottom, top, origin.

For Y.axis:

YAxisLocation; left, right, origin

module.exports is the object that's actually returned as the result of a require call.

The exports variable is initially set to that same object (i.e. it's a shorthand "alias"), so in the module code you would usually write something like this:

let myFunc1 = function() { ... };
let myFunc2 = function() { ... };
exports.myFunc1 = myFunc1;
exports.myFunc2 = myFunc2;

to export (or "expose") the internally scoped functions myFunc1 and myFunc2.

And in the calling code you would use:

const m = require('./mymodule');
m.myFunc1();

where the last line shows how the result of require is (usually) just a plain object whose properties may be accessed.

NB: if you overwrite exports then it will no longer refer to module.exports. So if you wish to assign a new object (or a function reference) to exports then you should also assign that new object to module.exports

It's worth noting that the name added to the exports object does not have to be the same as the module's internally scoped name for the value that you're adding, so you could have:

let myVeryLongInternalName = function() { ... };
exports.shortName = myVeryLongInternalName;
// add other objects, functions, as required

followed by:

const m = require('./mymodule');
m.shortName(); // invokes module.myVeryLongInternalName

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

Quote the Windows help for the set command (set /?):

If Command Extensions are enabled, then there are several dynamic
environment variables that can be expanded but which don't show up in
the list of variables displayed by SET.  These variable values are
computed dynamically each time the value of the variable is expanded.
If the user explicitly defines a variable with one of these names, then
that definition will override the dynamic one described below:

%CD% - expands to the current directory string.

%DATE% - expands to current date using same format as DATE command.

%TIME% - expands to current time using same format as TIME command.

%RANDOM% - expands to a random decimal number between 0 and 32767.

%ERRORLEVEL% - expands to the current ERRORLEVEL value

%CMDEXTVERSION% - expands to the current Command Processor Extensions
    version number.

%CMDCMDLINE% - expands to the original command line that invoked the
    Command Processor.

Note the %CD% - expands to the current directory string. part.

You should use > or < and == here. So the solution would be:

list.sort(function(item1, item2) {
    var val1 = item1.attr,
        val2 = item2.attr;
    if (val1 == val2) return 0;
    if (val1 > val2) return 1;
    if (val1 < val2) return -1;
});

>>> [5] * 4
[5, 5, 5, 5]

Be careful when the item being repeated is a list. The list will not be cloned: all the elements will refer to the same list!

>>> x=[5]
>>> y=[x] * 4
>>> y
[[5], [5], [5], [5]]
>>> y[0][0] = 6
>>> y
[[6], [6], [6], [6]]

$collection = collect([1, 2, 3, 4, 5, 6, 7, 8, 9]);

$chunk = $collection->forPage(2, 3);

$chunk->all();

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

Hex, Linq-fu:

string.Concat(ba.Select(b => b.ToString("X2")).ToArray())

UPDATE with the times

As noted by @RubenBartelink, the code that don't have a conversion of IEnumerable<string> to an array: ba.Select(b => b.ToString("X2")) does not work prior to 4.0, the same code is now working on 4.0.

This code...

byte[] ba = { 1, 2, 4, 8, 16, 32 };

string s = string.Concat(ba.Select(b => b.ToString("X2")));
string t = string.Concat(ba.Select(b => b.ToString("X2")).ToArray());

Console.WriteLine (s);
Console.WriteLine (t);

...prior to .NET 4.0, the output is:

System.Linq.Enumerable+<CreateSelectIterator>c__Iterator10`2[System.Byte,System.String]
010204081020

On .NET 4.0 onwards, string.Concat has an overload that accepts IEnumerable. Hence on 4.0, the above code will have same output for both variables s and t

010204081020
010204081020

Prior to 4.0, ba.Select(b => b.ToString("X2")) goes to overload (object arg0), the way for the IEnumerable<string> to go to a proper overload, i.e. (params string[] values), is we need to convert the IEnumerable<string> to string array. Prior to 4.0, string.Concat has 10 overload functions, on 4.0 it is now 12

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

You'd need to be careful as onBlur has some caveats in IE11 (How to use relatedTarget (or equivalent) in IE?, https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/relatedTarget).

There is, however, no way to use onFocusOut in React as far as I can tell. See the issue on their github https://github.com/facebook/react/issues/6410 if you need more information.

Recursively delete all children of the file ...

public static void DeleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory()) {
        for (File child : fileOrDirectory.listFiles()) {
            DeleteRecursive(child);
        }
    }

    fileOrDirectory.delete();
}

I'm sure there's some nice library that does this sort of thing already for you... But to just stick with the approach you're already going with, Map#entrySet gives you a combined Object with the key and the value. So something like:

for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println(entry.getKey() + ":" + entry.getValue().toString());
}

will do what you're after.

If you're using java 8, there's also the new streaming approach.

map.forEach((key, value) -> System.out.println(key + ":" + value));

By far the easiest solution is to just use the Google Chart API http://code.google.com/apis/chart/

You can make bar graphs, pie charts, use 3D, and it's as easy as building a url with some parameters. See the simple example below.

public static string NumberToWords(int number)
{
    if (number == 0)
        return "zero";

    if (number < 0)
        return "minus " + NumberToWords(Math.Abs(number));

    string words = "";

    if ((number / 1000000) > 0)
    {
        words += NumberToWords(number / 1000000) + " million ";
        number %= 1000000;
    }

    if ((number / 1000) > 0)
    {
        words += NumberToWords(number / 1000) + " thousand ";
        number %= 1000;
    }

    if ((number / 100) > 0)
    {
        words += NumberToWords(number / 100) + " hundred ";
        number %= 100;
    }

    if (number > 0)
    {
        if (words != "")
            words += "and ";

        var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
        var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

        if (number < 20)
            words += unitsMap[number];
        else
        {
            words += tensMap[number / 10];
            if ((number % 10) > 0)
                words += "-" + unitsMap[number % 10];
        }
    }

    return words;
}
