here's a gentle introduction to the js debugger in chrome that i wrote. Maybe it will help others looking for info on this: http://meeech.amihod.com/getting-started-with-javascript-debugging-in-chrome/

It's possible to use a udev rule to let the system decide on the scheduler based on some characteristics of the hw.
An example udev rule for SSDs and other non-rotational drives might look like

# set noop scheduler for non-rotating disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop"

inside a new udev rules file (e.g., /etc/udev/rules.d/60-ssd-scheduler.rules). This answer is based on the debian wiki

To check whether ssd disks would use the rule, it's possible to check for the trigger attribute in advance:

for f in /sys/block/sd?/queue/rotational; do printf "$f "; cat $f; done

You will also receive this error if you are passing an object back to the client that contains a property of type enum that is not set by default and that enum does not have a value that maps to 0. i.e enum MyEnum{ a=1, b=2};

The first one is the correct one, and IMHO the more efficient one, since the second 'solution' instantiates a new string instance.

Roman Samoylenko's answer was correct except the function has changed. The correct answer is

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);

I struggled to find the working solution with ApplicationContext and TYPE_SYSTEM_ALERT and found confusing solutions, In case you want the dialog should be opened from any activity even the dialog is a singleton you have to use getApplicationContext(), and if want the dialog should be TYPE_SYSTEM_ALERT you will need the following steps:

first get the instance of dialog with correct theme, also you need to manage the version compatibility as I did in my following snippet:

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext(), R.style.Theme_AppCompat_Light);

After setting the title, message and buttons you have to build the dialog as:

AlertDialog alert = builder.create();

Now the type plays the main roll here, since this is the reason of crash, I handled the compatibility as following:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        alert.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY - 1);

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        alert.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    }

Note: if you are using a custom dialog with AppCompatDialog as below:

AppCompatDialog dialog = new AppCompatDialog(getApplicationContext(), R.style.Theme_AppCompat_Light);

you can directly define your type to the AppCompatDialog instance as following:

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY - 1);

    } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
    }

Don't forget to add the manifest permission:

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

To add to Jerry and Joe's answers, if you're wanting to find the text BEFORE the last word you can use:

=TRIM(LEFT(SUBSTITUTE(TRIM(A1), " ", REPT(" ", LEN(TRIM(A1)))), LEN(SUBSTITUTE(TRIM(A1), " ", REPT(" ", LEN(TRIM(A1)))))-LEN(TRIM(A1))))

With 'My little cat' in A1 would result in 'My little' (where Joe and Jerry's would give 'cat'

In the same way that Jerry and Joe isolate the last word, this then just gets everything to the left of that (then trims it back)

• Open the command prompt and change the directory where your sdk is placed D:\Softwares\Android\sdk\tools\bin>

• now add your avdmanager in this,now your full code is D:\Softwares\Android\sdk\tools\bin>avdmanager list avd

• it will show you a list of emulator device that you have already created after few seconds

• now typecd..

• and run your emulator with this cmd, Here my emulator name is Tablet_API_25 so I have typed this name after the -avd.

  D:\Softwares\Android\sdk\tools>emulator -avd Tablet_API_25

EDIT : For Android Studio 3.2 or later, the path changes to D:\Softwares\Android\sdk\emulator\emulator -avd Tablet_API_25

i.e. %ANDROID_HOME%\tools\emulator -avd [AVD NAME]

As far as I know, an input element may not have a href attribute, which is where Fancybox gets its information about the content. The following code uses an a element instead of the input element. Also, this is what I would call the "standard way".

<html>
<head>
  <script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
  <script type="text/javascript" src="http://fancyapps.com/fancybox/source/jquery.fancybox.pack.js?v=2.0.5"></script>
  <link rel="stylesheet" type="text/css" href="http://fancyapps.com/fancybox/source/jquery.fancybox.css?v=2.0.5" media="screen" />
</head>
<body>

<a href="#divForm" id="btnForm">Load Form</a>

<div id="divForm" style="display:none">
  <form action="tbd">
    File: <input type="file" /><br /><br />
    <input type="submit" />
  </form>
</div>

<script type="text/javascript">
  $(function(){
    $("#btnForm").fancybox();
  });
</script>

Download mingw-get and simply issue:

mingw-get install gcc.

See the Getting Started page.

sudo gem install --no-user-install <gem-name>

will install your gem globally, i.e. it will be available to all user's contexts.

Instead of overwriting the html every time, just toggle the class.

$('#click_advance').click(function() {
    $('#display_advance').toggle('1000');
    $("i", this).toggleClass("icon-circle-arrow-up icon-circle-arrow-down");
});

To connect using a username/password and specifying ports, the code looks like this:

from pyhive import presto

cursor = presto.connect(host='host.example.com',
                    port=8081,
                    username='USERNAME:PASSWORD').cursor()

sql = 'select * from table limit 10'

cursor.execute(sql)

print(cursor.fetchone())
print(cursor.fetchall())

I had a related problem: the Visual C++ generators were not even on the list when running cmake --help.

I ran where cmake in console and found that cygwin also provides its own cmake.exe file, which was being used. Changing the order of directories in PATH fixed the problem.

$str = "Hello there folks!"
$str_ex = explode("there, $str, 2);   //explodes $string just twice
                                      //outputs: array ("Hello ", " folks")
$str_final = implode("", $str_ex);    // glues above array together
                                      // outputs: str("Hello  folks")

There is one more additional space but it didnt matter as it was for backgound script in my case.

$('#effective_to').datepicker({
    dateFormat: "dd-mm-yyyy",
    changeMonth: true,
    changeYear: true,
    beforeShow: function() { 
        $('#ui-datepicker-div').addClass('datepicker');
    }
});

CSS

.datepicker {
    z-index: 100000 !important;
    display: block;
}

This works form me. Even though I called model via ajax

I'm quite happy with my "make a weak pin storage program" solution. Maybe it will help people who need a very simple binary file IO example to follow.

$ ls
WeakPin  my_pin_code.pin  weak_pin.c
$ ./WeakPin
Pin: 45 47 49 32
$ ./WeakPin 8 2
$ Need 4 ints to write a new pin!
$./WeakPin 8 2 99 49
Pin saved.
$ ./WeakPin
Pin: 8 2 99 49
$
$ cat weak_pin.c
// a program to save and read 4-digit pin codes in binary format

#include <stdio.h>
#include <stdlib.h>

#define PIN_FILE "my_pin_code.pin"

typedef struct { unsigned short a, b, c, d; } PinCode;


int main(int argc, const char** argv)
{
    if (argc > 1)  // create pin
    {
        if (argc != 5)
        {
            printf("Need 4 ints to write a new pin!\n");
            return -1;
        }
        unsigned short _a = atoi(argv[1]);
        unsigned short _b = atoi(argv[2]);
        unsigned short _c = atoi(argv[3]);
        unsigned short _d = atoi(argv[4]);
        PinCode pc;
        pc.a = _a; pc.b = _b; pc.c = _c; pc.d = _d;
        FILE *f = fopen(PIN_FILE, "wb");  // create and/or overwrite
        if (!f)
        {
            printf("Error in creating file. Aborting.\n");
            return -2;
        }

        // write one PinCode object pc to the file *f
        fwrite(&pc, sizeof(PinCode), 1, f);  

        fclose(f);
        printf("Pin saved.\n");
        return 0;
    }

    // else read existing pin
    FILE *f = fopen(PIN_FILE, "rb");
    if (!f)
    {
        printf("Error in reading file. Abort.\n");
        return -3;
    }
    PinCode pc;
    fread(&pc, sizeof(PinCode), 1, f);
    fclose(f);

    printf("Pin: ");
    printf("%hu ", pc.a);
    printf("%hu ", pc.b);
    printf("%hu ", pc.c);
    printf("%hu\n", pc.d);
    return 0;
}

System.getProperties() can be overridden by calls to System.setProperty(String key, String value) or with command line parameters -Dfile.separator=/

File.separator gets the separator for the default filesystem.

FileSystems.getDefault() gets you the default filesystem.

FileSystem.getSeparator() gets you the separator character for the filesystem. Note that as an instance method you can use this to pass different filesystems to your code other than the default, in cases where you need your code to operate on multiple filesystems in the one JVM.

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

new Buffer(number)            // Old
Buffer.alloc(number)          // New

new Buffer(string)            // Old
Buffer.from(string)           // New

new Buffer(string, encoding)  // Old
Buffer.from(string, encoding) // New

new Buffer(...arguments)      // Old
Buffer.from(...arguments)     // New

Note that Buffer.alloc() is also faster on the current Node.js versions than new Buffer(size).fill(0), which is what you would otherwise need to ensure zero-filling.

To make it more specific Create a tracking branch, which means you are now tracking a remote branch.

git branch --track branch remote-branch
git branch --track exp remotes/origin/experimental

After which you can

git branch   # to see the remote tracking branch "exp" created .

Then to work on that branch do

git checkout branchname
git checkout exp

After you have made changes to the branch. You can git fetch and git merge with your remote tracking branch to merge your changes and push to the remote branch as below.

git fetch origin
git merge origin/experimental  
git push origin/experimental

Hope it helps and gives you an idea, how this works.

 <div className="form-group">
          <div className="checkbox">
            <label><input type="checkbox" value="" onChange={this.handleInputChange.bind(this)}  />Flagged</label>
            <br />
            <label><input type="checkbox" value=""  />Un Flagged</label>
          </div>
        </div

handleInputChange(event){

console.log("event",event.target.checked)   }

the Above handle give you the value of true or false upon checked or unChecked

Class that will call the methods:

namespace myNamespace
{
    public class myClass
    {
        public static void voidMethodWithoutParameters()
        {
            // code here
        }
        public static string stringReturnMethodWithParameters(string param1, string param2)
        {
            // code here
            return "output";
        }
    }
}

Calling myClass static methods using Reflection:

var myClassType = Assembly.GetExecutingAssembly().GetType(GetType().Namespace + ".myClass");
                    
// calling my void Method that has no parameters.
myClassType.GetMethod("voidMethodWithoutParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

// calling my string returning Method & passing to it two string parameters.
Object methodOutput = myClassType.GetMethod("stringReturnMethodWithParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, new object[] { "value1", "value1" });
Console.WriteLine(methodOutput.ToString());

Note: I don't need to instantiate an object of myClass to use it's methods, as the methods I'm using are static.

Great resources:

• How C# Reflection Works
• MethodBase.Invoke Method

Yes, this behaviour is guaranteed:

@Before:

The @Before methods of superclasses will be run before those of the current class, unless they are overridden in the current class. No other ordering is defined.

@After:

The @After methods declared in superclasses will be run after those of the current class, unless they are overridden in the current class.

Change the Maven preferences for plugin execution from error to ignore

Try this :

function missingCharacter($list) {

        // Create an array with a range from array minimum to maximu
        $newArray = range(min($list), max($list));

        // Find those elements that are present in the $newArray but not in given $list
        return array_diff($newArray, $list);
    }
print_r(missCharacter(array('a','b','d','g')));

you have to make you're function static like this

namespace Add_Function
{
  class Program
  {
    public static void(string[] args)
    {
       int a;
       int b;
       int c;

       Console.WriteLine("Enter value of 'a':");
       a = Convert.ToInt32(Console.ReadLine());

       Console.WriteLine("Enter value of 'b':");
       b = Convert.ToInt32(Console.ReadLine());

       //why can't I not use it this way?
       c = Add(a, b);
       Console.WriteLine("a + b = {0}", c);
    }
    public static int Add(int x, int y)
    {
        int result = x + y;
        return result;
     }
  }
}

you can do Program.Add instead of Add you also can make a new instance of Program by going like this

Program programinstance = new Program();

There are plenty of methods:

• Do not use Box Muller. Especially if you draw many gaussian numbers. Box Muller yields a result which is clamped between -6 and 6 (assuming double precision. Things worsen with floats.). And it is really less efficient than other available methods.
• Ziggurat is fine, but needs a table lookup (and some platform-specific tweaking due to cache size issues)
• Ratio-of-uniforms is my favorite, only a few addition/multiplications and a log 1/50th of the time (eg. look there).
• Inverting the CDF is efficient (and overlooked, why ?), you have fast implementations of it available if you search google. It is mandatory for Quasi-Random numbers.

It's not magic.

The behavior of this code in C is described in section 6.7.8.21 of the C specification (online draft of C spec): for the elements that don't have a specified value, the compiler initializes pointers to NULL and arithmetic types to zero (and recursively applies this to aggregates).

The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.

Also, note that in C++ (but not C), you can use an empty initializer list, causing the compiler to aggregate-initialize all of the elements of the array:

char array[100] = {};

As for what sort of code the compiler might generate when you do this, take a look at this question: Strange assembly from array 0-initialization

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

[{"id": "1", "name":"Aaa"}, {"id": "2", "name":"Bbb"}]

In above JSON data, you are showing that we have an array contaning the number of dictionaries.

You need to use this code for parsing it:

NSError *e = nil;
NSArray *JSONarray = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: &e];
        for(int i=0;i<[JSONarray count];i++)
        {
            NSLog(@"%@",[[JSONarray objectAtIndex:i]objectForKey:@"id"]);
             NSLog(@"%@",[[JSONarray objectAtIndex:i]objectForKey:@"name"]);
        }

For swift 3/3+

   //Pass The response data & get the Array
    let jsonData = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! [AnyObject]
    print(jsonData)
    // considering we are going to get array of dictionary from url

    for  item  in jsonData {
        let dictInfo = item as! [String:AnyObject]
        print(dictInfo["id"])
        print(dictInfo["name"])
    }

Catch the exception that happens to be a parent class in the exception hierarchy. This is of course, bad practice. In your case, the common parent exception happens to be the Exception class, and catching any exception that is an instance of Exception, is indeed bad practice - exceptions like NullPointerException are usually programming errors and should usually be resolved by checking for null values.

You have to use a custom parsing string. I also suggest to include the invariant culture to identify that this format does not relate to any culture. Plus, it will prevent a warning in some code analysis tools.

var date = DateTime.ParseExact(value, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);

Try this

 LayoutParams params = new LayoutParams(
            LayoutParams.WRAP_CONTENT,      
            LayoutParams.WRAP_CONTENT
    );
    params.setMargins(left, top, right, bottom);
    yourbutton.setLayoutParams(params);

    byte[] seed = (SALT2 + username + password).getBytes();
    SecureRandom random = new SecureRandom(seed);
    KeyGenerator generator;
    generator = KeyGenerator.getInstance("AES");
    generator.init(random);
    generator.init(256);
    Key keyObj = generator.generateKey();

I'm looking into using SSTJ for FFTs in Java. It can redirect via JNI to FFTW if the library is available or will use a pure Java implementation if not.

• Step 1. Install homebrew from here: http://brew.sh
• Step 1.1. Run export PATH=/usr/local/bin:$PATH
• Step 2. Run brew update
• Step 3. Run brew install vim && brew install macvim
• Step 4. Run brew link macvim

You now have the latest versions of vim and macvim managed by brew. Run brew update && brew upgrade every once in a while to upgrade them.

This includes the installation of the CLI mvim and the mac application (which both point to the same thing).

I use this setup and it works like a charm. Brew even takes care of installing vim with the preferable options.

Yes. There is a simple way to remove everything in iPython. In iPython console, just type:

%reset

Then system will ask you to confirm. Press y. If you don't want to see this prompt, simply type:

%reset -f

This should work..

Mostly the image is not displayed because you URL contains spaces. In your case you almost did everything correct. Except one thing - you have not added single quotes like you do if you specify background-image in css I.e.

.bg-img {                \/          \/
    background-image: url('http://...');
}

To do so escape quot character in HTML via \'

                                          \/                                  \/
<div [ngStyle]="{'background-image': 'url(\''+ item.color.catalogImageLink + '\')'}"></div>

I had an error when trying to git stash my local changes. The error from git said "Please tell me who you are" and then told me to "Run git config --global user.email "[email protected] and git config --global user.name "Your name" to set your account's default identity." However, you must Omit --global to set the identity only in your current repository.

map seems like the right tool for the job to me.

my_list = ['foo', 'fob', 'faz', 'funk']

See this section on functional programming tools for more examples of map.

See here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays/StringView (a C-like interface for strings based upon the JavaScript ArrayBuffer interface)

Here's my attempt at doing this:

Step 1: Create a style named SearchViewStyle

<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the search icon -->
    <item name="searchIcon">@drawable/search</item>
    <!-- Gets rid of the "underline" in the text -->
    <item name="queryBackground">@null</item>
    <!-- Gets rid of the search icon when the SearchView is expanded -->
    <item name="searchHintIcon">@null</item>
    <!-- The hint text that appears when the user has not typed anything -->
    <item name="queryHint">@string/search_hint</item>
</style>

Step 2: Create a layout named simple_search_view_item.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView
    android:layout_gravity="end"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    style="@style/SearchViewStyle"
    xmlns:android="http://schemas.android.com/apk/res/android" />  

Step 3: Create a menu item for this search view

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        app:actionLayout="@layout/simple_search_view_item"
        android:title="@string/search"
        android:icon="@drawable/search"
        app:showAsAction="always" />
</menu>  

Step 4: Inflate the menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_searchable_activity, menu);
    return true;
}  

Result:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar. If someone could help me do that then that'd be golden.

Use this snip : var IE = (navigator.userAgent.indexOf("Edge") > -1 || navigator.userAgent.indexOf("Trident/7.0") > -1) ? true : false;

If you want to get content of given directory, and only it (i.e. no subdirectories), the best way is to use opendir/readdir/closedir:

opendir my $dir, "/some/path" or die "Cannot open directory: $!";
my @files = readdir $dir;
closedir $dir;

You can also use:

my @files = glob( $dir . '/*' );

But in my opinion it is not as good - mostly because glob is quite complex thing (can filter results automatically) and using it to get all elements of directory seems as a too simple task.

On the other hand, if you need to get content from all of the directories and subdirectories, there is basically one standard solution:

use File::Find;

my @content;
find( \&wanted, '/some/path');
do_something_with( @content );

exit;

sub wanted {
  push @content, $File::Find::name;
  return;
}

Another way to do it is using the StructField if you have multiple fields that needs to be modified.

Ex:

from pyspark.sql.types import StructField,IntegerType, StructType,StringType
newDF=[StructField('CLICK_FLG',IntegerType(),True),
       StructField('OPEN_FLG',IntegerType(),True),
       StructField('I1_GNDR_CODE',StringType(),True),
       StructField('TRW_INCOME_CD_V4',StringType(),True),
       StructField('ASIAN_CD',IntegerType(),True),
       StructField('I1_INDIV_HHLD_STATUS_CODE',IntegerType(),True)
       ]
finalStruct=StructType(fields=newDF)
df=spark.read.csv('ctor.csv',schema=finalStruct)

Output:

Before

root
 |-- CLICK_FLG: string (nullable = true)
 |-- OPEN_FLG: string (nullable = true)
 |-- I1_GNDR_CODE: string (nullable = true)
 |-- TRW_INCOME_CD_V4: string (nullable = true)
 |-- ASIAN_CD: integer (nullable = true)
 |-- I1_INDIV_HHLD_STATUS_CODE: string (nullable = true)

After:

root
 |-- CLICK_FLG: integer (nullable = true)
 |-- OPEN_FLG: integer (nullable = true)

This is slightly a long procedure to cast , but the advantage is that all the required fields can be done.

It is to be noted that if only the required fields are assigned the data type, then the resultant dataframe will contain only those fields which are changed.

I was looking for a while for a solution to debug my threads and I found it here thanks to haridsv. I use slightly simplified version employing the traceback.print_stack():

import sys, traceback, signal
import threading
import os

def dumpstacks(signal, frame):
  id2name = dict((th.ident, th.name) for th in threading.enumerate())
  for threadId, stack in sys._current_frames().items():
    print(id2name[threadId])
    traceback.print_stack(f=stack)

signal.signal(signal.SIGQUIT, dumpstacks)

os.killpg(os.getpgid(0), signal.SIGQUIT)

For my needs I also filter threads by name.

This can be due to byte alignment and padding so that the structure comes out to an even number of bytes (or words) on your platform. For example in C on Linux, the following 3 structures:

#include "stdio.h"


struct oneInt {
  int x;
};

struct twoInts {
  int x;
  int y;
};

struct someBits {
  int x:2;
  int y:6;
};


int main (int argc, char** argv) {
  printf("oneInt=%zu\n",sizeof(struct oneInt));
  printf("twoInts=%zu\n",sizeof(struct twoInts));
  printf("someBits=%zu\n",sizeof(struct someBits));
  return 0;
}

Have members who's sizes (in bytes) are 4 bytes (32 bits), 8 bytes (2x 32 bits) and 1 byte (2+6 bits) respectively. The above program (on Linux using gcc) prints the sizes as 4, 8, and 4 - where the last structure is padded so that it is a single word (4 x 8 bit bytes on my 32bit platform).

oneInt=4
twoInts=8
someBits=4

The answers provided by other users here : How to SSH to a VirtualBox guest externally through a host?

... helped me to accomplish the task of connecting from out on the internet to my home computer's guest machine. You should be able to connect using computers, tablets, and smart phones (android, IPhone,etc). I add a few more step in case it might be helpful to someone else:

Here is a quick diagram of my setup:

• Remote device ---> INTERNET --> MODEM --> ROUTER --> HOST MACHINE --> GUEST VM

• Remote device (ssh client) ---> PASS THRU DEVICES ---> GUEST VM (ssh server)

• Remote device (leave ssh port 3022) ---> INTERNET --> MODEM --> ROUTER (FWD frm:p3022 to:p3022)--> HOST MACHINE (FWD frm:p3022 to:p22) --> GUEST VM (arrive ssh port 22)

The key for me was to realize that ALL connections was PASSING-THROUGH intermediary devices to get from my remote PC to my guest virtual-machine at home --Hence port forwarding!

Notes: * Need ssh client to request a secure connection and a running ssh server to process the secure connection.

• I will forward the port 3022 as used in the chosen answer from above.

• Enter your IPs where needed (home modem/router, host IP, guest IP,etc.), Names chosen are just examples-use or change.

1.Create ssh tunnel to port 3022 on your modem's IP / router's external IP address.

ssh client/device possible commands: ssh -p 3022 user-name@home_external_IP

2.Port forward = we are passing thru the connection from router to host machine

• Also make sure firewall /IPtable rules on router is allowing ports to be forward (open if needed)

• Router's Pfwd SCREEN required entries: AppName:SSH_Fwd, Port_from: 3022, Protocol:both (UDP/TCP), IP_address:hostIP_address, Port_to:3022, everything else can be blank

DD-WRT router software resources / Info:

• DD-WRT Port_Forwarding

• DD-WRT Static_DHCP

3.Host Machine Firewall: open port 3022 #so forwarded port can pass thru to guest machine

• Host Machine: Install VirtualBox, guest additions, and guest machine if not done already

• Configure guest machine and then follow the Network section below

• I used VirtualBox GUI to setup guest's network- easier than CLI

• If you want to use other methods refer to : VirtualBox/manual/ch06.html#natforward

4.Some suggest using Network Bridge adapter for guest = access to LAN and other machines on your LAN. This also pose an increase security risk, because now your guest machine is now exposed to LAN machines and possibly the INTERNET hackers if firewall not setup properly. So I selected Network adapter attached to NAT for less exposure to bridged security risks.

On the guest machine do the following:

• Guest Machine VirtualBox Network settings: Adapter 1: Attached to NAT
• Guest Machine VirtualBox Port Forwarding Rule: Name:External_SSH, Protocol:TCP, Host Port: 3022, Guest Port 22, Host&guest IPs:leave blank
• click on advance in Network section then click on Port forwarding to enter rules
• Guest Machine Firewall: open port 22 #so ssh connection can enter
• Guest Machine: Make sure that ssh server is installed, configured properly, and running
• LINUX test to see if ssh server running w/command: sudo service ssh status
• Can check netstat to see if connection made to port 22 on the guest machine

Also there are different ssh servers and clients depending on platform using.

• wikipedia/Secure_Shell
• wikipedia/Comparison_of_SSH_servers
• wikipedia/Comparison_of_SSH_clients

For Ubuntu Users:

• ubuntu community: SSHOpenSSH/Configuring
• ubuntu/community: OpenSSH/Keys

That should be it. If I made a mistake or want to add anything -feel free to do so-- I am still a noob.

Hope this helps someone. Good luck!

If you want to enumerate all possible subsets have a look at this paper. They discuss different approaches such as lexicographical order, gray coding and the banker's sequence. They give an example implementation of the banker's sequence and discuss different characteristics of the solutions e.g. performance.

Maybe you can pipe SQL query to sqlplus. It works for mysql:

echo "SELECT * FROM table" | mysql --user=username database

Create a Bower configuration file .bowerrc in the project root (as opposed to your home directory) with the content:

{
  "directory" : "public/components"
}

Run bower install again.

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

select substring(ColumnName, patindex('%[^0]%',ColumnName), 10)

Use listings package.

Simple configuration for LaTeX header (before \begin{document}):

\usepackage{listings}
\usepackage{color}

\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

\lstset{frame=tb,
  language=Java,
  aboveskip=3mm,
  belowskip=3mm,
  showstringspaces=false,
  columns=flexible,
  basicstyle={\small\ttfamily},
  numbers=none,
  numberstyle=\tiny\color{gray},
  keywordstyle=\color{blue},
  commentstyle=\color{dkgreen},
  stringstyle=\color{mauve},
  breaklines=true,
  breakatwhitespace=true,
  tabsize=3
}

You can change default language in the middle of document with \lstset{language=Java}.

Example of usage in the document:

\begin{lstlisting}
// Hello.java
import javax.swing.JApplet;
import java.awt.Graphics;

public class Hello extends JApplet {
    public void paintComponent(Graphics g) {
        g.drawString("Hello, world!", 65, 95);
    }    
}
\end{lstlisting}

Here's the result:

npm install -g npm@version

in which you want to downgrade

npm install -g [email protected]

you can use indexing if your enumerable type is string like below

((string[])MyEnumerableStringList)[0]

You can use  , aka a Non-Breaking Space.

It is essentially a standard space, the primary difference being that a browser should not break (or wrap) a line of text at the point that this   occupies.

Have you tried the SVG text element?

.append("text").text(function(d, i) { return d[whichevernode];})

rect element doesn't permit text element inside of it. It only allows descriptive elements (<desc>, <metadata>, <title>) and animation elements (<animate>, <animatecolor>, <animatemotion>, <animatetransform>, <mpath>, <set>)

Append the text element as a sibling and work on positioning.

UPDATE

Using g grouping, how about something like this? fiddle

You can certainly move the logic to a CSS class you can append to, remove from the group (this.parentNode)

Just as another solution:

Instead of creating the second column, you can categorize your string data(month name) and sort by that like this:

df.rename(columns={1:'month'},inplace=True)
df['month'] = pd.Categorical(df['month'],categories=['December','November','October','September','August','July','June','May','April','March','February','January'],ordered=True)
df = df.sort_values('month',ascending=False)

It will give you the ordered data by month name as you specified while creating the Categorical object.

Since the true Binding URL for the web service is located in the file, you could do these simple steps from your local machine:

1) Save the file to your local computer for example:

C:\Documents and Settings\[user]\Desktop\Webservice1.asmx

2) In Visual Studio Right Click on your project > Choose Add Web Reference, A dialog will open.

3) In the URL Box Copy the local file location above C:\Documents and Settings[user]\Desktop\Webservice1.asmx, Click Next

4) Now you will see the functions appear, choose your name for the reference, Click add reference

5) You are done! you can start using it as a namespace in your application don't worry that you used a local file, because anyway the true URL for the service is located in the file at the Binding section

You can do this with this library. https://github.com/itmor/events-js

const events = new Events();

events.add({  
  blockIsHidden: () =>  {
    if ($('div').css('display') === 'none') return true;
  }
});

function printText () {
  console.log('The block has become hidden!');
}

events.on('blockIsHidden', printText);

Restricting to few lines will work in almost all browsers, but an ellipsis(3 dots) will not be displayed in Firefox & IE. Demo - http://jsfiddle.net/ahzo4b91/1/

div {
width: 300px;
height: 2.8em;
line-height: 1.4em;
display: flex;
-webkit-line-clamp: 2;
display: -webkit-box;
-webkit-box-orient: vertical;
overflow: hidden; 
}

if you are using axios or other AJAX javascript library you may want to retrive the url and pass to the front end

you can do that with the code below

   $default = '/';

   $location = $request->session()->pull('url.intended', $default);

    return ['status' => 200, 'location' => $location];

This will return a json formatted string

this solution uses the jquery library

$('#elementId').append("<div class='classname'>content</div>");

In addition to the string operations (MOVS/INS/STOS/CMPS/SCASB/W/D/Q etc.) mentioned in the other answers, I wanted to add that there are also more "modern" x86 assembly instructions that implicitly use at least EDI/RDI:

The SSE2 MASKMOVDQU (and the upcoming AVX VMASKMOVDQU) instruction selectively write bytes from an XMM register to memory pointed to by EDI/RDI.

Why does response.json return a promise?

Because you receive the response as soon as all headers have arrived. Calling .json() gets you another promise for the body of the http response that is yet to be loaded. See also Why is the response object from JavaScript fetch API a promise?.

Why do I get the value if I return the promise from the then handler?

Because that's how promises work. The ability to return promises from the callback and get them adopted is their most relevant feature, it makes them chainable without nesting.

You can use

fetch(url).then(response => 
    response.json().then(data => ({
        data: data,
        status: response.status
    })
).then(res => {
    console.log(res.status, res.data.title)
}));

or any other of the approaches to access previous promise results in a .then() chain to get the response status after having awaited the json body.

if you declare it as float or any decimal format it will display

0

only

E.g :

declare @weight float;

SET @weight= 47 / 638; PRINT @weight

Output : 0

If you want the output as

0.073667712

E.g

declare @weight float;

SET @weight= 47.000000000 / 638.000000000; PRINT @weight

Managed Code

Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, "My code is managed by the CLR."

Visual Basic and C# can only produce managed code, so, if you're writing an application in one of those languages you are writing an application managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.

Unmanaged Code

Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.

No free memory management or anything else the CLR provides.

Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++.

Mixing the two

Since Visual C++ can be compiled to either managed or unmanaged code it is possible to mix the two in the same application. This blurs the line between the two and complicates the definition, but it's worth mentioning just so you know that you can still have memory leaks if, for example, you're using a third party library with some badly written unmanaged code.

Here's an example I found by googling:

#using <mscorlib.dll>
using namespace System;

#include "stdio.h"

void ManagedFunction()
{
    printf("Hello, I'm managed in this section\n");
}

#pragma unmanaged
UnmanagedFunction()
{
    printf("Hello, I am unmanaged through the wonder of IJW!\n");
    ManagedFunction();
}

#pragma managed
int main()
{
    UnmanagedFunction();
    return 0;
}

Dim WS as Worksheet
Set WS = Sheets.Add

You don't have to know where it's located, or what it's name is, you just refer to it as WS.
If you still want to do this the "old fashioned" way, try this:

Sheets.Add.Name = "Test"

I Found Solution Of You Question But In Stack Not Allow to Upload Video See the link below it show better explain

How to link two (multiple) workbooks and cells in Excel...

While I agree on using the TryParse method, a lot of people dislike the use of out parameter (myself included). With tuple support having been added to C#, an alternative is to create an extension method that will limit the number of times you use out to a single instance:

public static class StringExtensions
{
    public static (int result, bool canParse) TryParse(this string s)
    {
        int res;
        var valid = int.TryParse(s, out res);
        return (result: res, canParse: valid);
    }
}

(Source: C# how to convert a string to int)

No one of these answers gave me the solution, only worked with this:

mySpinner.post(new Runnable() {
    @Override
    public void run() {
        mySpinner.setSelection(position);
    }
});

Go to web.xml add <element> before <web-app> and close </element> after </web-app>

should be somethings like this

<?xml version="1.0" encoding="UTF-8"?>

<element>

<web-app>

....
</web-app>

</element>

Thanks Shuwaiee

I made a slight change though as using it in a Private Sub already.

Dim GetIPAddress()

Dim strHostName As String

Dim strIPAddress As String

strHostName = System.Net.Dns.GetHostName()

strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

But also made a change to the way the details are displayed so that they can show on seperate lines using & vbCrLf &

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

Hope this helps someone.

Add system variable (for Windows) "JAVA_TOOL_OPTIONS" = "-Dfile.encoding=UTF8".

EDIT: You cannot overload operators in current, common browser-based implementations of JavaScript interpreters.

To answer the original question, one way you could do this, and mind you, this is a bit of a hack, simply serialize the two arrays to JSON and then compare the two JSON strings. That would simply tell you if the arrays are different, obviously you could do this to each of the objects within the arrays as well to see which ones were different.

Another option is to use a library which has some nice facilities for comparing objects - I use and recommend MochiKit.

EDIT: The answer kamens gave deserves consideration as well, since a single function to compare two given objects would be much smaller than any library to do what I suggest (although my suggestion would certainly work well enough).

Here is a naïve implemenation that may do just enough for you - be aware that there are potential problems with this implementation:

function objectsAreSame(x, y) {
   var objectsAreSame = true;
   for(var propertyName in x) {
      if(x[propertyName] !== y[propertyName]) {
         objectsAreSame = false;
         break;
      }
   }
   return objectsAreSame;
}

The assumption is that both objects have the same exact list of properties.

Oh, and it is probably obvious that, for better or worse, I belong to the only-one-return-point camp. :)

For clarity purposes, I often use the select argument in subset. With newer folks, I've learned that keeping the # of commands they need to pick up to a minimum helps adoption. As their skills increase, so too will their coding ability. And subset is one of the first commands I show people when needing to select data within a given criteria.

Something like:

> subset(mtcars, select = c("mpg", "cyl", "vs", "am"))
                     mpg cyl vs am
Mazda RX4           21.0   6  0  1
Mazda RX4 Wag       21.0   6  0  1
Datsun 710          22.8   4  1  1
....

I'm sure this will test slower than most other solutions, but I'm rarely at the point where microseconds make a difference.

You can adjust pandas print options with set_printoptions.

In [3]: df.describe()
Out[3]: 
<class 'pandas.core.frame.DataFrame'>

However this will not work in all cases as pandas detects your console width and it will only use to_string if the output fits in the console (see the docstring of set_printoptions). In this case you can explicitly call to_string as answered by BrenBarn.

Alternatively, if you want to export a copy without modifying the working copy, you can use rsync:

rsync -a --exclude .svn path/to/working/copy path/to/export

Another useful resource:

• DBA_SYS_PRIVS
• DBA_TAB_PRIVS
• DBA_ROLE_PRIVS

Use:

background:url("location of image"); // Use an image with opacity

This method will work in all browsers.

Just a guess:

-ab 192

should be

-ab 192k

Seems like that could be a problem, but maybe ffmpeg is smart enough to correct it.

Maybe call Directory.GetParent in a loop? That's if you want the full path to each directory and not just the directory names.

Copy-pasteable code based on Pavlo Neyman's method

RedirectPost(string url, T bodyPayload) and GetPostData() are for those who just want to dump some strongly typed data in the source page and fetch it back in the target one. The data must be serializeable by NewtonSoft Json.NET and you need to reference the library of course.

Just copy-paste into your page(s) or better yet base class for your pages and use it anywhere in you application.

My heart goes out to all of you who still have to use Web Forms in 2019 for whatever reason.

        protected void RedirectPost(string url, IEnumerable<KeyValuePair<string,string>> fields)
        {
            Response.Clear();

            const string template =
@"<html>
<body onload='document.forms[""form""].submit()'>
<form name='form' action='{0}' method='post'>
{1}
</form>
</body>
</html>";

            var fieldsSection = string.Join(
                    Environment.NewLine,
                    fields.Select(x => $"<input type='hidden' name='{HttpUtility.UrlEncode(x.Key)}' value='{HttpUtility.UrlEncode(x.Value)}'>")
                );

            var html = string.Format(template, HttpUtility.UrlEncode(url), fieldsSection);

            Response.Write(html);

            Response.End();
        }

        private const string JsonDataFieldName = "_jsonData";

        protected void RedirectPost<T>(string url, T bodyPayload)
        {
            var json = JsonConvert.SerializeObject(bodyPayload, Formatting.Indented);
            //explicit type declaration to prevent recursion
            IEnumerable<KeyValuePair<string, string>> postFields = new List<KeyValuePair<string, string>>()
                {new KeyValuePair<string, string>(JsonDataFieldName, json)};

            RedirectPost(url, postFields);

        }

        protected T GetPostData<T>() where T: class 
        {
            var urlEncodedFieldData = Request.Params[JsonDataFieldName];
            if (string.IsNullOrEmpty(urlEncodedFieldData))
            {
                return null;// default(T);
            }

            var fieldData = HttpUtility.UrlDecode(urlEncodedFieldData);

            var result = JsonConvert.DeserializeObject<T>(fieldData);
            return result;
        }

.length = number of rows / column length

[0].length = number of columns / row length

You can use defaultdict:

>>> from collections import defaultdict
>>> d = defaultdict(list)
>>> a = ['1', '2']
>>> for i in a:
...   for j in range(int(i), int(i) + 2):
...     d[j].append(i)
...
>>> d
defaultdict(<type 'list'>, {1: ['1'], 2: ['1', '2'], 3: ['2']})
>>> d.items()
[(1, ['1']), (2, ['1', '2']), (3, ['2'])]

1 - You can script sshpass's ssh command like this:

#!/bin/bash

export SSHPASS=password
sshpass -e ssh -oBatchMode=no user@host

2 - You can script sshpass's sftp commandlike this:

#!/bin/bash

export SSHPASS=password

sshpass -e sftp -oBatchMode=no -b - user@host << !

SYSDATE, SYSTIMESTAMP returns the Database's date and timestamp, whereas current_date, current_timestamp returns the date and timestamp of the location from where you work.

For eg. working from India, I access a database located in Paris. at 4:00PM IST:

select sysdate,systimestamp from dual;

This returns me the date and Time of Paris:

RESULT

12-MAY-14   12-MAY-14 12.30.03.283502000 PM +02:00

select current_date,current_timestamp from dual;

This returns me the date and Time of India:

RESULT

12-MAY-14   12-MAY-14 04.00.03.283520000 PM ASIA/CALCUTTA

Please note the 3:30 time difference.

When using Child Component We check type like this.

Parent Component:

export default () => {

  const onChangeHandler = ((e: React.ChangeEvent<HTMLInputElement>): void => {
    console.log(e.currentTarget.value)
  }

  return (
    <div>
      <Input onChange={onChangeHandler} />
    </div>
  );
}

Child Component:

type Props = {
  onChange: (e: React.ChangeEvent<HTMLInputElement>) => void
}

export Input:React.FC<Props> ({onChange}) => (
  <input type="tex" onChange={onChange} />
)

SELECT DISTINCT (user_id) 
FROM [user]
WHERE user.user_id In (select user_id from user where ancestry = 'England') 
    And user.user_id In (select user_id from user where ancestry = 'France') 
    And user.user_id In (select user_id from user where ancestry = 'Germany');`

$_SERVER['HTTP_REFERER'] is the answer

I've made a proof-of-concept solution using jQuery.

View sample here.

I've now got this code in a Mercurial bitbucket repository. The main file is tables.html.

I'm aware of one issue with this: if the table contains anchors, and if you open the URL with the specified anchor in a browser, when the page loads, the row with the anchor will probably be obscured by the floating header.

Update 2017-12-11: I see this doesn't work with current Firefox (57) and Chrome (63). Not sure when and why this stopped working, or how to fix it. But now, I think the accepted answer by Hendy Irawan is superior.

1. Right click to the project and select the property menu item
2. goto C/C++ -> Precompiled Headers
3. Select Not Using Precompiled Headers

https://docs.python.org/library/stdtypes.html#comparisons

is tests for identity == tests for equality

Each (small) integer value is mapped to a single value, so every 3 is identical and equal. This is an implementation detail, not part of the language spec though

Try This:

//Check
document.getElementById('checkbox').setAttribute('checked', 'checked');

//UnCheck
document.getElementById('chk').removeAttribute('checked');

Note, do not use Chrome's built in Speed Tester (it will show you unthrottled speed). Instead use another site, like Fast.com. That will show you properly throttled speeds.

Also, the throttling settings might be hidden and can be accessed from the network bar by clicking the tiny down arrow.

You haven't at time of writing described what you are going to do with the response or what its content type is. An answer already contains a very basic usage of MSXML2.XMLHTTP (I recommend the more explicit MSXML2.XMLHTTP.3.0 progID) however you may need to do different things with the response, it may not be text.

The XMLHTTP also has a responseBody property which is a byte array version of the reponse and there is a responseStream which is an IStream wrapper for the response.

Note that in a server-side requirement (e.g., VBScript hosted in ASP) you would use MSXML.ServerXMLHTTP.3.0 or WinHttp.WinHttpRequest.5.1 (which has a near identical interface).

Here is an example of using XmlHttp to fetch a PDF file and store it:-

Dim oXMLHTTP
Dim oStream

Set oXMLHTTP = CreateObject("MSXML2.XMLHTTP.3.0")

oXMLHTTP.Open "GET", "http://someserver/folder/file.pdf", False
oXMLHTTP.Send

If oXMLHTTP.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write oXMLHTTP.responseBody
    oStream.SaveToFile "c:\somefolder\file.pdf"
    oStream.Close
End If

Well, there is a very easy way if you're using Eclipse.

Export your project as a "Runnable" Jar file (right-click project folder from within Eclipse, select "Export..."). When you configure the export settings, be sure to select "Extract required libraries into generated Jar." Keep in mind, select "Extract..." and not "Package required libraries...".

Additionally: You must select a run-configuration in your export settings. So, you could always create an empty main( ) in some class and use it for your run configuration.

Anyway, it isn't guaranteed to work 100% of the time - as you will notice a pop-up message telling you to make sure you check the licenses of the Jar files you're including and something about not copying signature files. However, I have been doing this for years and have never encountered a problem.

This simple example illustrates it:

MR_COUNT = 0        # constant defined on main Object class
module Foo
  MR_COUNT = 0
  ::MR_COUNT = 1    # set global count to 1
  MR_COUNT = 2      # set local count to 2
end

puts MR_COUNT       # this is the global constant: 1
puts Foo::MR_COUNT  # this is the local constant: 2

Taken from http://www.tutorialspoint.com/ruby/ruby_operators.htm

Typically a .sh file is a shell script which you can execute in a terminal. Specifically, the script you mentioned is a bash script, which you can see if you open the file and look in the first line of the file, which is called the shebang or magic line.

This is how I do it:

 with open(txtfile, 'r') as infile, open(csvfile, 'w') as outfile:
        stripped = (line.strip() for line in infile)
        lines = (line.split(",") for line in stripped if line)
        writer = csv.writer(outfile)
        writer.writerows(lines)

Hope it helps!

This answer is updated for Xcode 11.

App Store Connect currently asks for images in the following categories:

iPhone 6.5" Display

This is 1242 x 2688 pixels. You can create this size image using the iPhone 11 Pro Max simulator.

iPhone 5.5" Display

This is 1242 x 2208 pixels. You can create this size image using the iPhone 8 Plus simulator.

iPad Pro (3rd gen) 12.9" Display

That is 2048 x 2732 pixels. You can create this size image using the iPad Pro (12.9-inch) (3rd generation) simulator.

iPad Pro (2nd gen) 12.9" Display

That is 2048 x 2732 pixels. This is the exact same size as the iPad Pro (12.9-inch) (3rd generation), so most people can use the same screenshots here. But see this.

Notes

• Use File > New Screen Shot (Command+S) in the simulator to save a screenshot to the desktop. On a real device press Sleep/Wake+Home on the iPhone/iPad (images available in Photo app)
• The pixel dimensions above are the full screen portrait orientation sizes. You shouldn't include the status bar, so you can either paste background color over the status bar text and icons or crop them out and scale the image back up.
• See this link for more details.

If you are "Rebasing", "Already started rebase" which you want to cancel, just comment (#) all commits listed in rebase editor.

As a result you will get a command line message

Nothing to do

You need to uncomment max_input_vars value in php.ini file and increase it (exp. 2000), also dont forget to restart your server this will help for 99,99%.

Just include preventDefault() function in the code,

$("#txtSearchProdAssign").keydown(function (e) 
{
   if (e.keyCode == 13) 
   {
       e.preventDefault();
       $('input[name = butAssignProd]').click();
   }
});

\d is a digit (a character in the range 0-9), and + means 1 or more times. So, \d+ is 1 or more digits.

This is about as simple as regular expressions get. You should try reading up on regular expressions a little bit more. Google has a lot of results for regular expression tutorial, for instance. Or you could try using a tool like the free Regex Coach that will let you enter a regular expression and sample text, then indicate what (if anything) matches the regex.

The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.

param([String[]] $Hosts, [String] $VLAN)

Instead of

foreach ($i in $args)

you can use

foreach ($hostName in $Hosts)

If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:

myScript.ps1 -Hosts host1,host2,host3 -VLAN 2

...or something similar.

I'm not sure about the circumstances where you need to convert an NSInteger to an int.

NSInteger is just a typedef:

NSInteger Used to describe an integer independently of whether you are building for a 32-bit or a 64-bit system.

#if __LP64__ || TARGET_OS_EMBEDDED || TARGET_OS_IPHONE || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 
typedef long NSInteger;
#else
typedef int NSInteger;
#endif

You can use NSInteger any place you use an int without converting it.

You can use something like this:
HTML:

<div><input class="yourClass" type="checkbox" value="1" checked></div>
<div><input class="yourClass" type="checkbox" value="2"></div>
<div><input class="yourClass" type="checkbox" value="3" checked></div>
<div><input class="yourClass" type="checkbox" value="4"></div>

JQuery:

$(".yourClass:checkbox").filter(":checked")

It will choose values of 1 and 3.

Here my code with expressJS:

router.route('/wordslike/:word')
    .get(function(request, response) {
            var word = request.params.word;       
            Word.find({'sentence' : new RegExp(word, 'i')}, function(err, words){
               if (err) {response.send(err);}
               response.json(words);
            });
         });

You need to implement the equals() method in your MyClass.

The reason that == didn't work is this is checking that they refer to the same instance. Since you did new for each, each one is a different instance.

The reason that equals() didn't work is because you didn't implement it yourself yet. I believe it's default behavior is the same thing as ==.

Note that you should also implement hashcode() if you're going to implement equals() because a lot of java.util Collections expect that.

Some awk version.

awk '/19:55/{c=5} c-->0'
awk '/19:55/{c=5} c && c--'

When pattern found, set c=5
If c is true, print and decrease number of c

I am taking an example of date given below and print two different format of dates according to your requirements.

String date="01/10/2014 05:54:00 PM";

SimpleDateFormat simpleDateFormat=new SimpleDateFormat("dd/MM/yyyy hh:mm:ss aa",Locale.getDefault());

try {
            Log.i("",""+new SimpleDateFormat("ddMMyyyyHHmmss",Locale.getDefault()).format(simpleDateFormat.parse(date)));

            Log.i("",""+new SimpleDateFormat("dd/MM/yyyy HH:mm:ss",Locale.getDefault()).format(simpleDateFormat.parse(date)));

        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

If you still have any query, Please respond. Thanks.

Both "arrA" & "arrB" can be accessed (print it out). However, can't get a size of "arrB".

What is a problem there?

1. Is 'char[]' incomplete type? or
2. 'sizeof' does not accept the extern variable/ label?

In my program, "arrA" & "arrB" are constant lists and fixed before to compile. I would like to use a label(let me easy to maintenance & save RAM memory).

your project is created using an old version of django-admin.py, older than django1.3

to fix this create another django project and copy its manage.py and paste it in the old one

This was what fixed it for me. (I had already tried toggling the capabilities on/off, recreating the provisioning profile, etc).

In the Build Settings tab, in Code Signing Entitlements, my .entitlements file wasn't link for all sections. Once I added it to the Any SDK section, the error was resolved.

On Ubuntu 18.04, I ran into this issue because the apt package for wheel does not include the wheel command. I think pip tries to import the wheel python package, and if that succeeds assumes that the wheel command is also available. Ubuntu breaks that assumption.

The apt python3 code package is named python3-wheel. This is installed automatically because python3-pip recommends it.

The apt python3 wheel command package is named python-wheel-common. Installing this too fixes the "failed building wheel" errors for me.

Swift 4 solution:

    cell.imageView?.image = UIImage(named: "yourImageName")

In programmatically, add the background image

RadioButton radioButton = new RadioButton(this);
radioButton.setBackground(R.drawable.account_background);
rg.addView(radioButton);

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

Save your username, password and sever name in an RDP file and run the RDP file from your script

If it is in the same class it is fine to trust the method.

It is very common to do this. It is good practice to check null values in constructor's and method's arguments to make sure that nobody is passing null values into them (if it is not allowed). Then if you implement your methods in a way that they never set the "start" graph to null, don't check for nulls there.

It is also good practice to implement unit tests for your methods and make sure that they are correctly implemented, so you can trust them.

If you're using RVM on OS X, you probably need to run this:

rvm osx-ssl-certs update all

More information here: http://rvm.io/support/fixing-broken-ssl-certificates

And here is the full explanation: https://github.com/wayneeseguin/rvm/blob/master/help/osx-ssl-certs.md

Update

On Ruby 2.2, you may have to reinstall Ruby from source to fix this. Here's how (replace 2.2.3 with your Ruby version):

rvm reinstall 2.2.3 --disable-binary

Nope, that is pretty much the best way to do it. As a machine could have several IP addresses you need to iterate the collection of them to find the proper one.

Edit: The only thing I would change would be to change this:

if (ip.AddressFamily.ToString() == "InterNetwork")

to this:

if (ip.AddressFamily == AddressFamily.InterNetwork)

There is no need to ToString an enumeration for comparison.

Found it at http://www.linuxquestions.org/questions/suse-novell-60/howto-kill-defunct-processes-574612/

2) Here a great tip from another user (Thxs Bill Dandreta): Sometimes

kill -9 <pid>

will not kill a process. Run

ps -xal

the 4th field is the parent process, kill all of a zombie's parents and the zombie dies!

Example

4 0 18581 31706 17 0 2664 1236 wait S ? 0:00 sh -c /usr/bin/gcc -fomit-frame-pointer -O -mfpmat
4 0 18582 18581 17 0 2064 828 wait S ? 0:00 /usr/i686-pc-linux-gnu/gcc-bin/3.3.6/gcc -fomit-fr
4 0 18583 18582 21 0 6684 3100 - R ? 0:00 /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/cc1 -quie

18581, 18582, 18583 are zombies -

kill -9 18581 18582 18583

has no effect.

kill -9 31706

removes the zombies.

Another way is to use a utility function (you could make this a static method of a generic utility class if you like):

byte[] concat(byte[]...arrays)
{
    // Determine the length of the result array
    int totalLength = 0;
    for (int i = 0; i < arrays.length; i++)
    {
        totalLength += arrays[i].length;
    }

    // create the result array
    byte[] result = new byte[totalLength];

    // copy the source arrays into the result array
    int currentIndex = 0;
    for (int i = 0; i < arrays.length; i++)
    {
        System.arraycopy(arrays[i], 0, result, currentIndex, arrays[i].length);
        currentIndex += arrays[i].length;
    }

    return result;
}

Invoke like so:

byte[] a;
byte[] b;
byte[] result = concat(a, b);

It will also work for concatenating 3, 4, 5 arrays, etc.

Doing it this way gives you the advantage of fast arraycopy code which is also very easy to read and maintain.

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

Using sortBy... could help.

$users = User::all()->with('rated')->get()->sortByDesc('rated.rating');

I found that when within a Miniconda3 environment I had to run:

conda deactivate

Neither deactivate nor source deactivate worked for me.

The usual way to check whether something can be converted to an int is to try it and see, following the EAFP principle:

try:
    int_value = int(string_value)
except ValueError:
    # it wasn't an int, do something appropriate
else:
    # it was an int, do something appropriate

So, in your case:

for item in mylist:
    try:
        int_value = int(item)
    except ValueError:
        pass
    else:
        mynewlist.append(item) # or append(int_value) if you want numbers

In most cases, a loop around some trivial code that ends with mynewlist.append(item) can be turned into a list comprehension, generator expression, or call to map or filter. But here, you can't, because there's no way to put a try/except into an expression.

But if you wrap it up in a function, you can:

def raises(func, *args, **kw):
    try:
        func(*args, **kw)
    except:
        return True
    else:
        return False

mynewlist = [item for item in mylist if not raises(int, item)]

… or, if you prefer:

mynewlist = filter(partial(raises, int), item)

It's cleaner to use it this way:

def raises(exception_types, func, *args, **kw):
    try:
        func(*args, **kw)
    except exception_types:
        return True
    else:
        return False

This way, you can pass it the exception (or tuple of exceptions) you're expecting, and those will return True, but if any unexpected exceptions are raised, they'll propagate out. So:

mynewlist = [item for item in mylist if not raises(ValueError, int, item)]

… will do what you want, but:

mynewlist = [item for item in mylist if not raises(ValueError, item, int)]

… will raise a TypeError, as it should.

I don't know of any built in method. But, coding by hand is not too difficult. Assuming the elements of the array you are dealing with are NSNumber objects of integer type, and 'arr' is the NSMutableArray that you want to reverse.

int n = [arr count];
for (int i=0; i<n/2; ++i) {
  id c  = [[arr objectAtIndex:i] retain];
  [arr replaceObjectAtIndex:i withObject:[arr objectAtIndex:n-i-1]];
  [arr replaceObjectAtIndex:n-i-1 withObject:c];
}

Since you start with a NSArray then you have to create the mutable array first with the contents of the original NSArray ('origArray').

NSMutableArray * arr = [[NSMutableArray alloc] init];
[arr setArray:origArray];

Edit: Fixed n -> n/2 in the loop count and changed NSNumber to the more generic id due to the suggestions in Brent's answer.

On the latest version of MacOS Big Sur (clean/first install)

This command works as it should and installs Xcode

xcode-select --install

Once you start writing code that can return a myriad of exit statuses, you start #define'ing all of them. In this case EXIT_SUCCESS makes sense in context of not being a "magic number". This makes your code more readable because every other exit code will be EXIT_SOMETHING. If you simply write a program that will return when it's done, return 0 is valid, and probably even cleaner because it suggests that there's no sophisticated return code structure.

If you use jquery, it can be done by using $(window).height();

<iframe src="html_intro.asp" width="100%" class="myIframe">
<p>Hi SOF</p>
</iframe>

<script type="text/javascript" language="javascript"> 
$('.myIframe').css('height', $(window).height()+'px');
</script>

Something else you can try if you are having issues encoding to 'utf-8' and want to go cell by cell you could try the following.

Python 2

(Where "df" is your DataFrame object.)

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = unicode(x.encode('utf-8','ignore'),errors ='ignore') if type(x) == unicode else unicode(str(x),errors='ignore')
            df.set_value(idx,column,x)
        except Exception:
            print 'encoding error: {0} {1}'.format(idx,column)
            df.set_value(idx,column,'')
            continue

Then try:

df.to_csv(file_name)

You can check the encoding of the columns by:

for column in df.columns:
    print '{0} {1}'.format(str(type(df[column][0])),str(column))

Warning: errors='ignore' will just omit the character e.g.

IN: unicode('Regenexx\xae',errors='ignore')
OUT: u'Regenexx'

Python 3

for column in df.columns:
    for idx in df[column].index:
        x = df.get_value(idx,column)
        try:
            x = x if type(x) == str else str(x).encode('utf-8','ignore').decode('utf-8','ignore')
            df.set_value(idx,column,x)
        except Exception:
            print('encoding error: {0} {1}'.format(idx,column))
            df.set_value(idx,column,'')
            continue

With closure:

   class TextFieldWithClosure: UITextField {
    var targetAction: (() -> Void)? {
        didSet {
            self.addTarget(self, action: #selector(self.targetSelector), for: .editingChanged)
        }
    }

    func targetSelector() {
        self.targetAction?()
    }
    }

and using

textField.targetAction? = {
 // will fire on text changed
 }

check, if this works for you.

File -> Settings -> (type appe in search box) and select Appearance -> Select Intellij from dropdown option of Theme on the right (under UI Options).

Hope this helps someone.

While this is very likely to be lost at the bottom of so many answers, the top solutions here were not working for me.
As far as I could tell neither would any of the other answers have helped.

Situation:
In an HTML5 page I had a menu that was a nav element inside a header (not THE header but a header in another element).
I wanted the navigation to stick to the top once a user scrolled to it, but previous to this the header was absolute positioned (so I could have it overlay something else slightly).
The solutions above never triggered a change because .offsetTop was not going to change as this was an absolute positioned element. Additionally the .scrollTop property was simply the top of the top most element... that is to say 0 and always would be 0.
Any tests I performed utilizing these two (and same with getBoundingClientRect results) would not tell me if the top of the navigation bar ever scrolled to the top of the viewable page (again, as reported in console, they simply stayed the same numbers while scrolling occurred).

Solution
The solution for me was utilizing

window.visualViewport.pageTop

The value of the pageTop property reflects the viewable section of the screen, therefore allowing me to track where an element is in reference to the boundaries of the viewable area.

Probably unnecessary to say, anytime I am dealing with scrolling I expect to use this solution to programatically respond to movement of elements being scrolled.
Hope it helps someone else.
IMPORTANT NOTE: This appears to work in Chrome and Opera currently & definitely not in Firefox (6-2018)... until Firefox supports visualViewport I recommend NOT using this method, (and I hope they do soon... it makes a lot more sense than the rest).


UPDATE:
Just a note regarding this solution.
While I still find what I discovered to be very valuable for situations in which "...programmatically respond to movement of elements being scrolled." is applicable. The better solution for the problem that I had was to use CSS to set position: sticky on the element. Using sticky you can have an element stay at the top without using javascript (NOTE: there are times this will not work as effectively as changing the element to fixed but for most uses the sticky approach will likely be superior)

UPDATE01:
So I realized that for a different page I had a requirement where I needed to detect the position of an element in a mildly complex scrolling setup (parallax plus elements that scroll past as part of a message). I realized in that scenario that the following provided the value I utilized to determine when to do something:

  let bodyElement = document.getElementsByTagName('body')[0];
  let elementToTrack = bodyElement.querySelector('.trackme');
  trackedObjPos = elementToTrack.getBoundingClientRect().top;
  if(trackedObjPos > 264)
  {
    bodyElement.style.cssText = '';
  }

Hope this answer is more widely useful now.

I assume we are talking about doing this in Bash?

I like to use sed to load the date values into an array so I can break down each field and do whatever I want with it. The following example assumes and input format of mm/dd/yyyy...

DATE=$2
DATE_ARRAY=(`echo $DATE | sed -e 's/\// /g'`)
MONTH=(`echo ${DATE_ARRAY[0]}`)
DAY=(`echo ${DATE_ARRAY[1]}`)
YEAR=(`echo ${DATE_ARRAY[2]}`)
LOAD_DATE=$YEAR$MONTH$DAY

you also may want to read up on the date command in linux. It can be very useful: http://unixhelp.ed.ac.uk/CGI/man-cgi?date

Hope that helps... :)

In Spring, bean scope is used to decide which type of bean instance should be returned from Spring container back to the caller.

5 types of bean scopes are supported :

1. Singleton : It returns a single bean instance per Spring IoC container.This single instance is stored in a cache of such singleton beans, and all subsequent requests and references for that named bean return the cached object.If no bean scope is specified in bean configuration file, default to singleton.

2. Prototype : It returns a new bean instance each time when requested. It does not store any cache version like singleton.

3. Request : It returns a single bean instance per HTTP request.

   

4. Session : It returns a single bean instance per HTTP session (User level session).

5. GlobalSession : It returns a single bean instance per global HTTP session. It is only valid in the context of a web-aware Spring ApplicationContext (Application level session).

In most cases, you may only deal with the Spring’s core scope – singleton and prototype, and the default scope is singleton.

Additionally, you could use just the same variable for the member of the input list which is currently accessed and for the element inside this member. However, this might even make it more (list) incomprehensible.

input = [[1, 2], [3, 4]]
[x for x in input for x in x]

First for x in input is evaluated, leading to one member list of the input, then, Python walks through the second part for x in x during which the x-value is overwritten by the current element it is accessing, then the first x defines what we want to return.

> myMatrix <- matrix(1:10, nrow=2)
> rownames(myMatrix) <- c("A", "B")
> colnames(myMatrix) <- c("A", "B", "C", "D", "E")

> myMatrix
  A B C D  E
A 1 3 5 7  9
B 2 4 6 8 10

> myMatrix["A", "A"]
[1] 1

> myMatrix["A", ]
A B C D E 
1 3 5 7 9 

> myMatrix[, "A"]
A B 
1 2 

If you have a multi-dimensional array, none of the previously mentioned solutions will work. Here is my solution:

public function arrayValuesToInt(&$array){
  if(is_array($array)){
    foreach($array as &$arrayPiece){
      arrayValuesToInt($arrayPiece);
    }
  }else{
    $array = intval($array);
  }
}

Then, just do this:

arrayValuesToInt($multiDimentionalArray);

This will make an array like this:

[["1","2"]["3","4"]]

look like this:

[[1,2][3,4]]

This will work with any level of depth.

Alternatively, you can use array_walk_recursive() for a shorter answer:

array_walk_recursive($array, function(&$value){
    $value = intval($value);
});

You can find your created database, named <your-database-name>

in

//data/data/<Your-Application-Package-Name>/databases/<your-database-name>

Pull it out using File explorer and rename it to have .db3 extension to use it in SQLiteExplorer

Use File explorer of DDMS to navigate to emulator directory.

I am guessing you are using a 32 bit eclipse with 32 bit JVM. It wont allow heapsize above what you have specified.

Using a 64-bit Eclipse with a 64-bit JVM helps you to start up eclipse with much larger memory. (I am starting with -Xms1024m -Xmx4000m)

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

See this answer for description.

On your click function, just add:

window.location.href = "The URL where you want to redirect";
$('#id').click(function(){
    window.location.href = "http://www.google.com";
});

My answer is very similar to the one from @biscoop, but I am going to elaborate a bit as it may apply to the question or to other people.

I had a .xls that was an extraction from one of our webapps. The Excel connection would not work (error message: "no tables or views could be loaded"). As a side note, when opening the file, there would be a warning stating that the file was from an online source and that the content needed activation.

I tried to save the same file as an .xlsx and it worked. I tried to save the same file with another name as an .xls and it worked too. So as a last test I only opened the source .xls file, clicking save and the connection worked.

Short answer: just try and see if opening the file and saving does the trick.

1. You can always set up cascading deletes on the relationships of the tables.

2. You can encapsulate the multiple deletes in one stored procedure.

3. You can use a transaction to ensure one unit of work.

Actually I found the best solution is the following:

$cur_dir = explode('\\', getcwd());
echo $cur_dir[count($cur_dir)-1];

if your dir is www\var\path\ Current_Path

then this returns Current_path

Vertical align only works in some select cases. The easiest way to make it function is to set display: table in the parent element's CSS and display: table-cell; to the child element and then apply your vertical align attribute.

Perhaps the best two browser techs for this are Canvas, with Flash as a back up.

We tried VML on IE as backup for Canvas, but it was much slower than Flash. SVG was slower then all the rest.

With jSignature ( http://willowsystems.github.com/jSignature/ ) we used Canvas as primary, with fallback to Flash-based Canvas emulator (FlashCanvas) for IE8 and less. Id' say worked very well for us.

as of 2017 this is more responsive and worked for me. This is for putting text inside vs over, like a badge. instead of the number 8, I had a variable to pull data from a database.

this code started with Kailas's answer up above

https://jsfiddle.net/jim54729/memmu2wb/3/

My HTML

<div class="containerBox">
  <img class="img-responsive"    src="https://s20.postimg.org/huun8e6fh/Gold_Ring.png">
  <div class='text-box'>
   <p class='dataNumber'> 8 </p>
  </div>
</div>

and my css:

.containerBox {
  position: relative;
  display: inline-block;
}

.text-box {
  position: absolute;
  height: 30%;
  text-align: center;
  width: 100%;
  margin: auto;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
  font-size: 30px;
}

.img-responsive {
  display: block;
  max-width: 100%;
  height: 120px;
  margin: auto;
  padding: auto;
}

.dataNumber {
  margin-top: auto;
}

I had to run the following command:

sudo apt-get autoremove phpmyadmin

Then I cleared my cache and it worked!

$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');

Your code has two problems:

1. The selector .IsBestAnswe does not match what you thought
2. It's addClass(), not addclass().

Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer') part to add only:

$('.IsBestAnswer').addClass('bestanswer');

You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer vs. bestanswer).

The best way to go about it would be to get a SynchronizationContext from the UI thread and use it. This class abstracts marshalling calls to other threads, and makes testing easier (in contrast to using WPF's Dispatcher directly). For example:

class MyViewModel
{
    private readonly SynchronizationContext _syncContext;

    public MyViewModel()
    {
        // we assume this ctor is called from the UI thread!
        _syncContext = SynchronizationContext.Current;
    }

    // ...

    private void watcher_Changed(object sender, FileSystemEventArgs e)
    {
         _syncContext.Post(o => DGAddRow(crp.Protocol, ft), null);
    }
}

(Windows mysql config)

Step 1 : Go To Apache Control Panel > Apache > Config > PHP.ini

Step 2 : Search in Notepad (Ctrl+F) For: ;extension_dir = "" (could be commented with a ;). Replace this line with: extension_dir = "C:\php\ext" (please do not you need to remove the ; on the beginning of the sentence).

Step 3 : Search For: extension=php_mysql.dll and remove the ; in the beginning.

Step 4 : Save and Restart You Apache HTTP Server. (On Windows this usually done via a UI)

That's it :)

If you get errors about missing php_mysql.dll you'll probably need to download this file from either the php.net site or the pecl.php.net. (Please be causius about where you get it from)

See here: Cross Browser favicon

Thats the way to go:

<link rel="icon" type="image/png" href="http://www.example.com/image.png"><!-- Major Browsers -->
<!--[if IE]><link rel="SHORTCUT ICON" href="http://www.example.com/alternateimage.ico"/><![endif]--><!-- Internet Explorer-->

CSS can do that with background-size: cover;

But to be more detailed and support more browsers...

Use aspect ratio like this:

 aspectRatio      = $bg.width() / $bg.height();

HI im going to leave this here cz i cant comment due to restrictions but i found AlexFitiskin's answer perfect, but a small correction was needed

document.getElementById('here').innerHTML = data.name; 

This needed to be changed to

document.getElementById('here').innerHTML = data.n;

I know that after five years the owner of the post will not find it of any importance but this is for people who might come across in the future .

For Android 5 (lollipop) you will have to use android:actionBarPopupTheme to set the textColor for the overflow menu.

You have to call next() before you can start reading values from the first row. beforeFirst puts the cursor before the first row, so there's no data to read.

Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.

Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.

EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)

public class Job
{
        public string id { get; set; }
        public string position_title { get; set; }
        public string organization_name { get; set; }
        public string rate_interval_code { get; set; }
        public int minimum { get; set; }
        public int maximum { get; set; }
        public string start_date { get; set; }
        public string end_date { get; set; }
        public List<string> locations { get; set; }
        public string url { get; set; }
}

And an edit to your code:

        List<Job> model = null;
        var client = new HttpClient();
        var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
          .ContinueWith((taskwithresponse) =>
          {
              var response = taskwithresponse.Result;
              var jsonString = response.Content.ReadAsStringAsync();
              jsonString.Wait();
              model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);

          });
        task.Wait();

This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.

EDIT 2:

There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:

http://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/

If you don't use the STL, then the code looks a lot bit like C.

#include <cstdlib>
#include <new>

template< class T >
void append_to_array( T *&arr, size_t &n, T const &obj ) {
    T *tmp = static_cast<T*>( std::realloc( arr, sizeof(T) * (n+1) ) );
    if ( tmp == NULL ) throw std::bad_alloc( __FUNCTION__ );
       // assign things now that there is no exception
    arr = tmp;
    new( &arr[ n ] ) T( obj ); // placement new
    ++ n;
}

T can be any POD type, including pointers.

Note that arr must be allocated by malloc, not new[].

The var_dump function displays structured information about variables/expressions including its type and value. Arrays are explored recursively with values indented to show structure. It also shows which array values and object properties are references.

The print_r() displays information about a variable in a way that's readable by humans. array values will be presented in a format that shows keys and elements. Similar notation is used for objects.

Example:

$obj = (object) array('qualitypoint', 'technologies', 'India');

var_dump($obj) will display below output in the screen.

object(stdClass)#1 (3) {
 [0]=> string(12) "qualitypoint"
 [1]=> string(12) "technologies"
 [2]=> string(5) "India"
}

And, print_r($obj) will display below output in the screen.

stdClass Object ( 
 [0] => qualitypoint
 [1] => technologies
 [2] => India
)

If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.

The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.

JVM heap size can be growable and shrinkable by the Garbage-Collection mechanism. But, it can't allocate over maximum memory size: Runtime.maxMemory. This is the meaning of maximum memory. Total memory means the allocated heap size. And free memory means the available size in total memory.

example) java -Xms20M -Xmn10M -Xmx50M ~~~. This means that jvm should allocate heap 20M on start(ms). In this case, total memory is 20M. free memory is 20M-used size. If more heap is needed, JVM allocate more but can't over 50M(mx). In the case of maximum, total memory is 50M, and free size is 50M-used size. As for minumum size(mn), if heap is not used much, jvm can shrink heap size to 10M.

This mechanism is for efficiency of memory. If small java program run on huge fixed size heap memory, so much memory may be wasteful.

You can use the pg_typeof() function, which also works well for arbitrary values.

SELECT pg_typeof("stu_id"), pg_typeof(100) from student_details limit 1;

This might be your problem:

height: .05em;

Chrome is a bit funky with decimals, so try a fixed-pixel height:

height: 2px;

You can use the :nth-child pseudo class like this:

.countTable table table td:nth-child(2)

Note though, this won't work in older browsers (or IE), you'll need to give the cells a class or use javascript in that case.

You can only use aggregates for comparison in the HAVING clause:

GROUP BY ...
  HAVING SUM(cash) > 500

The HAVING clause requires you to define a GROUP BY clause.

To get the first row where the sum of all the previous cash is greater than a certain value, use:

SELECT y.id, y.cash
  FROM (SELECT t.id,
               t.cash,
               (SELECT SUM(x.cash)
                  FROM TABLE x
                 WHERE x.id <= t.id) AS running_total
         FROM TABLE t
     ORDER BY t.id) y
 WHERE y.running_total > 500
ORDER BY y.id
   LIMIT 1

Because the aggregate function occurs in a subquery, the column alias for it can be referenced in the WHERE clause.

I think you had the correct idea with your last example. You only got an error because you were trying to put quotes inside an already quoted string. This will fix it:

gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output ($_.GetValue("DisplayName") + "`n") }

Edit: Keith's $() operator actually creates a better syntax (I always forget about this one). You can also escape quotes inside quotes as so:

gci -path hklm:\software\microsoft\windows\currentversion\uninstall | ForEach-Object -Process { write-output "$($_.GetValue(`"DisplayName`"))`n" }

function Person(firstname, lastname) {
  this.firstname = firstname;

  this.lastname = lastname;
  this.getfullname = function () {
    return `${this.firstname}   ${this.lastname}`;
  };

  let that = this;
  this.sayHi = function() {
    console.log(`i am this , ${this.firstname}`);
    console.log(`i am that , ${that.firstname}`);
  };
}

let thisss = new Person('thatbetty', 'thatzhao');

let thatt = {firstname: 'thisbetty', lastname: 'thiszhao'};

thisss.sayHi.call(thatt);

You can make any dimension of list

list=[]
n= int(input())
for i in range(0,n) :
    #num = input()
    list.append(input().split())
print(list)

output:

1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.

1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.

C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.

You can specify a format string if you don't want to use the e-notation.

#!/bin/bash

req=$(curl -s -X GET http://host:8080/some/resource -H "Accept: application/json") 2>&1
echo "${req}"

Better Solution compared to trimming the value of the textarea.

$('textarea[maxlength]').live('keypress', function(e) {
    var maxlength = $(this).attr('maxlength');
    var val = $(this).val();

    if (val.length > maxlength) {
        return false;
    }
});

You can use ssh to forward ports onto somewhere else.

If you have two computers, one you browse from, and one which is free to access websites, and is not logged (ie. you own it and it's sitting at home), then you can set up a tunnel between them to forward http traffic over.

For example, I connect to my home computer from work using ssh, with port forwarding, like this:

ssh -L 22222:<target_website>:80 <home_computer>

Then I can point my browser to

http://localhost:22222/

And this request will be forwarded over ssh. Since the work computer is first contacting the home computer, and then contacting the target website, it will be hard to log.

However, this is all getting into 'how to bypass web proxies' and the like, and I suggest you create a new question asking what exactly you want to do.

Ie. "How do I bypass web proxies to avoid my traffic being logged?"

If you want to consider null values equality too, try the following

select column1, column2, 
   case
      when column1 is NULL and column2 is NULL then 'true'  
      when column1=column2 then 'true' 
      else 'false' 
   end 
from table;

I hope I am not overstating the obvious, but why not do it directly in the ASP side? Unless you are dynamically altering the SQL based on certain conditions in your program, you should avoid codebehind as much as possible.

You could do the above all in ASP directly without code using the SqlDataSource control and a property in your dropdownlist.

<asp:GridView ID="gvSubjects" runat="server" DataKeyNames="SubjectID" OnRowDataBound="GridView_RowDataBound" OnDataBound="GridView_DataBound">
    <Columns>
        <asp:TemplateField HeaderText="Subjects">
            <ItemTemplate>
                <asp:DropDownList ID="ddlSubjects" runat="server" DataSourceID="sdsSubjects" DataTextField="SubjectName" DataValueField="SubjectID">
                </asp:DropDownList>
                <asp:SqlDataSource ID="sdsSubjects" runat="server"
                    SelectCommand="SELECT SubjectID,SubjectName FROM Students.dbo.Subjects"></asp:SqlDataSource>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

OpenSSL provides a passwd command that can encrypt but doesn't decrypt as it only does hashes. You could also download something like aesutil so you can use a capable and well-known symmetric encryption routine.

For example:

#!/bin/sh    
# using aesutil
SALT=$(mkrand 15) # mkrand generates a 15-character random passwd
MYENCPASS="i/b9pkcpQAPy7BzH2JlqHVoJc2mNTBM=" # echo "passwd" | aes -e -b -B -p $SALT 
MYPASS=$(echo "$MYENCPASS" | aes -d -b -p $SALT)

# and usage
serverControl.sh -u admin -p $MYPASS -c shutdown

I like to use continue in loops where there are a lot of contitions to be fulfilled before you get "down to business". So instead of code like this:

for x, y in zip(a, b):
    if x > y:
        z = calculate_z(x, y)
        if y - z < x:
            y = min(y, z)
            if x ** 2 - y ** 2 > 0:
                lots()
                of()
                code()
                here()

I get code like this:

for x, y in zip(a, b):
    if x <= y:
        continue
    z = calculate_z(x, y)
    if y - z >= x:
        continue
    y = min(y, z)
    if x ** 2 - y ** 2 <= 0:
        continue
    lots()
    of()
    code()
    here()

By doing it this way I avoid very deeply nested code. Also, it is easy to optimize the loop by eliminating the most frequently occurring cases first, so that I only have to deal with the infrequent but important cases (e.g. divisor is 0) when there is no other showstopper.

Mysql-native has been outdated so it became MySQL2 that is a new module created with the help of the original MySQL module's team. This module has more features and I think it has what you want as it has prepared statements(by using.execute()) like in PHP for more security.

It's also very active(the last change was from 2-1 days) I didn't try it before but I think it's what you want and more.

I tried as below.

I called ng-click to angularjs controller on Encourage button,

               <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" ng-click="setUsername({{user.userName}})" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

I set userName of encouragementModal from angularjs controller.

    /**
     * Encouragement controller for AngularJS
     * 
     * @param $scope
     * @param $http
     * @param encouragementService
     */
    function EncouragementController($scope, $http, encouragementService) {
      /**
       * set invoice number
       */
      $scope.setUsername = function (username) {
            $scope.userName = username;
      };
     }
    EncouragementController.$inject = [ '$scope', '$http', 'encouragementService' ];

I provided a place(userName) to get value from angularjs controller on encouragementModal.

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

It worked and I saluted myself.

I have fixed the same issue with below steps

1. Open project directory Using Terminal (which you are using i.e. mintty )
2. Now install composer within this directory as per given directions on https://getcomposer.org/download/

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php -r "if (hash_file('SHA384', 'composer-setup.php') === 'the-provided-hash-code') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php php -r "unlink('composer-setup.php');"

3. Now run your command.

Everything is working fine now because the composer.phar file is available within the current project directory.

thanks

public void methodOnClick(View view){

Button.setBackgroundResource(R.drawable.nameImage);

}

i recommend use button inside LinearLayout for adjust to size of Linear.

Kenny's solution is deprecated use this, i'm using actions class to double click but you can do anything.

new FluentWait<>(driver).withTimeout(30, TimeUnit.SECONDS).pollingEvery(5, TimeUnit.SECONDS)
                    .ignoring(StaleElementReferenceException.class)
                    .until(new Function() {

                    @Override
                    public Object apply(Object arg0) {
                        WebElement e = driver.findelement(By.xpath(locatorKey));
                        Actions action = new Actions(driver);
                        action.moveToElement(e).doubleClick().perform();
                        return true;
                    }
                });

I had the same problem and I'm using Ubuntu 15.10.

In my case, to solve this issue, I installed the package php7.0-xml using the Synaptic package manager, which include SimpleXml. So, after restart my Apache server, my problem was solved. This package came in the Debian version and you can find it here: https://packages.debian.org/sid/php7.0-xml.

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;
});

You can run the script with python -m from the relevant root dir. And pass the "modules path" as argument.

Example: $ python -m module.sub_module.main # Notice there is no '.py' at the end.

Another example:

$ tree  # Given this file structure
.
+-- bar
¦   +-- __init__.py
¦   +-- mod.py
+-- foo
    +-- __init__.py
    +-- main.py

$ cat foo/main.py
from bar.mod import print1
print1()

$ cat bar/mod.py
def print1():
    print('In bar/mod.py')

$ python foo/main.py  # This gives an error
Traceback (most recent call last):
  File "foo/main.py", line 1, in <module>
    from bar.mod import print1
ImportError: No module named bar.mod

$ python -m foo.main  # But this succeeds
In bar/mod.py

goto cpanel and login as Main Admin or Super Administrator

1. find SSH/Shell Access ( you will find under the security tab of cpanel )

2. now give the username and password of Super Administrator as root or whatyougave

   note: do not give any username, cos, it needs permissions
   

3. once your into console type

   type ' mysql ' and press enter now you find youself in

   mysql> /* and type here like */

   mysql> set global net_buffer_length=1000000;

   Query OK, 0 rows affected (0.00 sec)

   mysql> set global max_allowed_packet=1000000000;

   Query OK, 0 rows affected (0.00 sec)

Now upload and enjoy!!!

Here's another approach, in case you want split a string with a delimiter.

import pyspark.sql.functions as f

df = spark.createDataFrame([("1:a:2001",),("2:b:2002",),("3:c:2003",)],["value"])
df.show()
+--------+
|   value|
+--------+
|1:a:2001|
|2:b:2002|
|3:c:2003|
+--------+

df_split = df.select(f.split(df.value,":")).rdd.flatMap(
              lambda x: x).toDF(schema=["col1","col2","col3"])

df_split.show()
+----+----+----+
|col1|col2|col3|
+----+----+----+
|   1|   a|2001|
|   2|   b|2002|
|   3|   c|2003|
+----+----+----+

I don't think this transition back and forth to RDDs is going to slow you down... Also don't worry about last schema specification: it's optional, you can avoid it generalizing the solution to data with unknown column size.

We just ran into this same issue. Our Cpanel has expanded from PHP only to PHP and .NET and defaulted to .NET.

Log in to you Cpanel and make sure you don’t have the same issue.

Maybe not the best solution, (will rewrite history) but you could also do git reset --hard <hash of detached head commit>.

Your should create ptr as follows:

char *ptr;

You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.

Edit: complete code should be:

char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));
