Here is a step-by-step guide on how to generate and display QR code using ZXing library without having to install the third-party application. Note: you don't have to build ZXing with ANT or any other build tool. The file core.jar is available in the released zip archive (read below).

1. Download the latest release of ZXing. -- (ZXing-*.zip)
2. Extract this zip archive and find core.jar under core/ directory.
3. If you are using Eclipse IDE, drag and drop core.jar to the libs directory of your Android project. When asked, select Copy.
4. Copy the two classes given below (Contents.java & QRCodeEncoder.java) to the main package of your Android project.
5. Create an ImageView item in your Activity to display the generated QR code in if you don't have one already. An example is given below:
6. Use the code snippet below to generate the QR code in Bitmap format and display it in an ImageView.

Here is an ImageView element to add to your Activity layout XML file:

<ImageView 
    android:id="@+id/qrCode"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="50dp"
    android:layout_centerHorizontal="true"/>

Code snippet:

// ImageView to display the QR code in.  This should be defined in 
// your Activity's XML layout file
ImageView imageView = (ImageView) findViewById(R.id.qrCode);

String qrData = "Data I want to encode in QR code";
int qrCodeDimention = 500;

QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(qrData, null,
        Contents.Type.TEXT, BarcodeFormat.QR_CODE.toString(), qrCodeDimention);

try {
    Bitmap bitmap = qrCodeEncoder.encodeAsBitmap();
    imageView.setImageBitmap(bitmap);
} catch (WriterException e) {
    e.printStackTrace();
}

Here is Contents.java

As already mentioned, awk is the right tool for this. If you don't want to use awk, instead of parsing output of "ls -l" line by line, you could iterate over all files and do an "ls -l" for each individual file like this:

for x in * ; do echo `ls -ld $x` ; done

You won't gain anything by checking that the key exists. This is the code of HashMap:

@Override
public boolean containsKey(Object key) {
    Entry<K, V> m = getEntry(key);
    return m != null;
}

@Override
public V get(Object key) {
    Entry<K, V> m = getEntry(key);
    if (m != null) {
        return m.value;
    }
    return null;
}

Just check if the return value for get() is different from null.

This is the HashMap source code.

Other answers are correct but do it in a short way like

if(editText.getText().toString().isEmpty()) {
     // editText is empty
} else {
     // editText is not empty
}

Im new to RoR this is what I found out. you can directly render a json format

def YOUR_METHOD_HERE
  users = User.all
  render json: {allUsers: users} # ! rendering all users

Javascript has push and pop methods, which operate on ordinary Javascript array objects.

For queues, look here:

http://safalra.com/web-design/javascript/queues/

Queues can be implemented in JavaScript using either the push and shift methods or unshift and pop methods of the array object. Although this is a simple way to implement queues, it is very inefficient for large queues — because of the methods operate on arrays, the shift and unshift methods move every element in the array each time they are called.

Queue.js is a simple and efficient queue implementation for JavaScript whose dequeue function runs in amortized constant time. As a result, for larger queues, it can be significantly faster than using arrays.

My solution was to use a short nickname (less than 31 characters) and then write the entire name in cell 0.

Amiram's answer is correct, but Distinct() as implemented is an N² operation; for each item in the list, the algorithm compares it to all the already processed elements, and returns it if it's unique or ignores it if not. We can do better.

A sorted list can be deduped in linear time; if the current element equals the previous element, ignore it, otherwise return it. Sorting is NlogN, so even having to sort the collection, we get some benefit:

public static IEnumerable<T> SortAndDedupe<T>(this IEnumerable<T> input)
{
   var toDedupe = input.OrderBy(x=>x);

   T prev;
   foreach(var element in toDedupe)
   {
      if(element == prev) continue;

      yield return element;
      prev = element;      
   }
}

//Usage
dtList  = dtList.Where(s => !string.IsNullOrWhitespace(s)).SortAndDedupe().ToList();

This returns the same elements; they're just sorted.

How about:

00 00  *  *   * every 3 days && echo test

Where every is a script:

#!/bin/sh

case $2 in
    days)
        expr `date +%j` % $1 = 0 > /dev/null
        ;;

    weeks)
        expr `date +%V` % $1 = 0 > /dev/null
        ;;

    months)
        expr `date +%m` % $1 = 0 > /dev/null
        ;;
esac

So it runs every day.

Using */3 runs on the 3rd, 6th, ... 27th, 30th of the month, but is then wrong after a month has a 31st day. The every script is only wrong after the end of the year.

One should use a third party script for this called called ngStorage here is a example how to use.It updates localstorage with change in scope/view.

Move the parent div to the middle with

left: 50%;
top: 50%;
margin-left: -50px;

Move the second layer over the other with

position: relative;
left: -100px;

Or just simply using the datetime standard module

In [2]: from datetime import timezone, datetime
   ...: int(datetime.now(tz=timezone.utc).timestamp() * 1000)
   ...: 
Out[2]: 1514901741720

You can truncate or multiply depending on the resolution you want. This example is outputting millis.

If you want a proper Unix timestamp (in seconds) remove the * 1000

parseDouble() method is used to initialise a STRING (which should contains some numerical value)....the value it returns is of primitive data type, like int, float, etc.

But valueOf() creates an object of Wrapper class. You have to unwrap it in order to get the double value. It can be compared with a chocolate. The manufacturer wraps the chocolate with some foil or paper to prevent from pollution. The user takes the chocolate, removes and throws the wrapper and eats it.

Observe the following conversion.

int k = 100; Integer it1 = new Integer(k);

The int data type k is converted into an object, it1 using Integer class. The it1 object can be used in Java programming wherever k is required an object.

The following code can be used to unwrap (getting back int from Integer object) the object it1.

int m = it1.intValue();

System.out.println(m*m); // prints 10000

//intValue() is a method of Integer class that returns an int data type.

var currentDateTime = dateTime.Now();

Use the source, Luke.

No, but seriously I found that building Node.js from source, running the tests, and looking at the benchmarks did get me on the right track. From there, the .js files in the lib directory are a good place to look, especially the file http.js.

Update: I wrote this answer over a year ago, and since that time there has an explosion in the number of great resources available for people learning Node.js. Though I still believe diving into the source is worthwhile, I think that there are now better ways to get started. I would suggest some of the books on Node.js that are starting to come out.

"[a-zA-Z]" matches only one character. To match multiple characters, use "[a-zA-Z]+".

Since a dot is a joker for any character, you have to mask it: "abc\." To make the dot optional, you need a question mark: "abc\.?"

If you write the Pattern as literal constant in your code, you have to mask the backslash:

System.out.println ("abc".matches ("abc\\.?"));
System.out.println ("abc.".matches ("abc\\.?"));
System.out.println ("abc..".matches ("abc\\.?"));

Combining both patterns:

System.out.println ("abc.".matches ("[a-zA-Z]+\\.?"));

Instead of a-zA-Z, \w is often more appropriate, since it captures foreign characters like äöüßø and so on:

System.out.println ("abc.".matches ("\\w+\\.?"));   

Here's some more benchmarks for Docker based memcached server versus host native memcached server using Twemperf benchmark tool https://github.com/twitter/twemperf with 5000 connections and 20k connection rate

I used almost all of the answers posted here but not comfortable with that so i dig one step furter and found easy solution that fits my need and feel worth sharing with you guys.
Instead of iteration all over the options or using JQuery you can do using core JS in simple steps:

Example

<select id="org_list">
  <option value="23">IBM</option>
  <option value="33">DELL</option>
  <option value="25">SONY</option>
  <option value="29">HP</option>
</select>

So you must know the value of the option to select.

function selectOrganization(id){
    org_list=document.getElementById('org_list');
    org_list.selectedIndex=org_list.querySelector('option[value="'+id+'"]').index;
}

How to Use?

selectOrganization(25); //this will select SONY from option List

Your comments are welcome. :) AzmatHunzai.

FWIW, I had exactly the same question, but I could not find the answer here. It's probably not portable, but at least for gitolite, I can run the following to get what I want:

$ ssh [email protected] info
hello akim, this is gitolite 2.3-1 (Debian) running on git 1.7.10.4
the gitolite config gives you the following access:
     R   W     android
     R   W     bistro
     R   W     checkpn
...

You are definitely missing a small thing and that is you are not setting a default value:

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));

So the code would look like:

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());

Explanation: If you want to change the time zone, set the default time zone using TimeZone.setDefault()

The accepted solution does not work unless the browser takes up the full screen,

This seems to always work

  const popupCenterScreen = (url, title, w, h, focus) => {
    const top = (screen.height - h) / 4, left = (screen.width - w) / 2;
    const popup = window.open(url, title, `scrollbars=yes,width=${w},height=${h},top=${top},left=${left}`);
    if (focus === true && window.focus) popup.focus();
    return popup;
  }

Impl:

some.function.call({data: ''})
    .then(result =>
     popupCenterScreen(
         result.data.url,
         result.data.title, 
         result.data.width, 
         result.data.height, 
         true));

Introducing a new method signature that changes the parameter types is called overloading:

public boolean equals(People other){

Here People is different than Object.

When a method signature remains the identical to that of its superclass, it is called overriding and the @Override annotation helps distinguish the two at compile-time:

@Override
public boolean equals(Object other){

Without seeing the actual declaration of age, it is difficult to say why the error appears.

Easy way:

• Rename missingmen.txt to missingmen.html.
• Add a single line to the top of missingmen.html:
  <link href="txtstyle.css" rel="stylesheet" type="text/css" />
• Create a file called txtstyle.css, and add to it a line like this:
  html, body {font-family:Helvetica, Arial, sans-serif}

When you start a thread, it begins executing a function you give it (if you're extending threading.Thread, the function will be run()). To end the thread, just return from that function.

According to this, you can also call thread.exit(), which will throw an exception that will end the thread silently.

It's still valid to use IE=edge,chrome=1.

But, since the chrome frame project has been wound down the chrome=1 part is redundant for browsers that don't already have the chrome frame plug in installed.

I use the following for correctness nowadays

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

One possibility is that the target .NET Framework version of the class library is higher than that of the project.

np.maximum not only compares elementwise but also compares array elementwise with single value

>>>np.maximum([23, 14, 16, 20, 25], 18)
array([23, 18, 18, 20, 25])

As this is only tagged sql (which does not indicate any specific DBMS), here is a solution for Postgres:

select d::date 
from generate_series(date '1990-01-01', date '1990-01-01' + interval '100' year, interval '1' day) as t(d);

If you need that a lot, it's more efficient to store that in an table (which can e.g. be indexed):

create table calendar 
as
select d::date as the_date
from generate_series(date '1990-01-01', date '1990-01-01' + interval '100' year, interval '1' day) as t(d);

BuildToolsVersion & Dependencies must be same with Base API version.

buildToolsVersion '23.0.2' & compile 

&

com.android.support:appcompat-v7:24.0.0-alpha1

can not match with base API level.

It should be

compile 'com.android.support:appcompat-v7:21.0.3'

Done

I would think your own suggestion is correct, however the xml is not quite valid. If you are running the //book[title[@lang='it']] on <root>[Your"XML"Here]</root> then the free online xPath testers such as one here will find the expected result.

You can globally set printing options. I think this should work:

Method 1:

pd.set_option('display.max_columns', None)
pd.set_option('display.max_rows', None)

Method 2:

pd.options.display.max_columns = None
pd.options.display.max_rows = None

This will allow you to see all column names & rows when you are doing .head(). None of the column name will be truncated.

If you just want to see the column names you can do:

print(df.columns.tolist())

If you have a proxy, you also have to clear SOCKS in

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

I've combined some of the above answers to come up with this to ensure that a given path entry exists exactly as given with as much brevity as possible and no junk echos on the command line.

I had the same problem, and it came from a wrong client_id / Facebook App ID.

Did you switch your Facebook app to "public" or "online ? When you do so, Facebook creates a new app with a new App ID.

You can compare the "client_id" parameter value in the url with the one in your Facebook dashboard.

Also Make sure your app is public. Click on + Add product Now go to products => Facebook Login Now do the following:

Valid OAuth redirect URIs : example.com/

In AngularJS the best place to define Custom Validation is Cutsom directive. AngularJS provide a ngMessages module.

ngMessages is a directive that is designed to show and hide messages based on the state of a key/value object that it listens on. The directive itself complements error message reporting with the ngModel $error object (which stores a key/value state of validation errors).

For custom form validation One should use ngMessages Modules with custom directive.Here i have a simple validation which will check if number length is less then 6 display an error on screen

 <form name="myform" novalidate>
                <table>
                    <tr>
                        <td><input name='test' type='text' required  ng-model='test' custom-validation></td>
                        <td ng-messages="myform.test.$error"><span ng-message="invalidshrt">Too Short</span></td>
                    </tr>
                </table>
            </form>

Here is how to create custom validation directive

angular.module('myApp',['ngMessages']);
        angular.module('myApp',['ngMessages']).directive('customValidation',function(){
            return{
            restrict:'A',
            require: 'ngModel',
            link:function (scope, element, attr, ctrl) {// 4th argument contain model information 

            function validationError(value) // you can use any function and parameter name 
                {
                 if (value.length > 6) // if model length is greater then 6 it is valide state
                 {
                 ctrl.$setValidity('invalidshrt',true);
                 }
                 else
                 {
                 ctrl.$setValidity('invalidshrt',false) //if less then 6 is invalide
                 }

                 return value; //return to display  error 
                }
                ctrl.$parsers.push(validationError); //parsers change how view values will be saved in the model
            }
            };
        });

$setValidity is inbuilt function to set model state to valid/invalid

std::list<Object> l; 
std::list<Object>::iterator ptr;
int i;

for( i = 0 , ptr = l.begin() ; i < N && ptr != l.end() ; i++ , ptr++ );

if( ptr == l.end() ) {
    // list too short  
} else {
    // 'ptr' points to N-th element of list
}

This code is working for me either paste from right click or direct copy paste

   $('.textbox').on('paste input propertychange', function (e) {
        $(this).val( $(this).val().replace(/[^0-9.]/g, '') );
    })

When i paste Section 1: Labour Cost it becomes 1 in text box.

To allow only float value i use this code

 //only decimal
    $('.textbox').keypress(function(e) {
        if(e.which == 46 && $(this).val().indexOf('.') != -1) {
            e.preventDefault();
        } 
       if (e.which == 8 || e.which == 46) {
            return true;
       } else if ( e.which < 48 || e.which > 57) {
            e.preventDefault();
      }
    });

In addition to the answers above:

If you created/edited your .sh script file in Windows, make sure it was saved with line ending in Unix format. By default many editors in Windows will convert Unix line endings to Windows format and Linux will not recognize shebang (#!/bin/sh) at the beginning of the file. So Linux will produce the error message like if there is no shebang.

Tips:

• If you use Notepad++, you need to click "Edit/EOL Conversion/UNIX (LF)"
• If you use Visual Studio, I would suggest installing "End Of Line" plugin. Then you can make line endings visible by pressing Ctrl-R, Ctrl-W. And to set Linux style endings you can press Ctrl-R, Ctrl-L. For Windows style, press Ctrl-R, Ctrl-C.

The limitation of execl is that when executing a shell command or any other script that is not in the current working directory, then we have to pass the full path of the command or the script. Example:

execl("/bin/ls", "ls", "-la", NULL);

The workaround to passing the full path of the executable is to use the function execlp, that searches for the file (1st argument of execlp) in those directories pointed by PATH:

execlp("ls", "ls", "-la", NULL);

if still not resolved try adding this to your package.js scripts

"scripts": { "gulp": "gulp" },

and run npm run gulp it will runt gulp scripts from gulpfile.js

Using mysqli i've created following function. Asuming you have an mysqli instance called $con.

function table_exist($table){
    global $con;
    $table = $con->real_escape_string($table);
    $sql = "show tables like '".$table."'";
    $res = $con->query($sql);
    return ($res->num_rows > 0);
}

Hope it helps.

Warning: as sugested by @jcaron this function could be vulnerable to sqlinjection attacs, so make sure your $table var is clean or even better use parameterised queries.

Use the javascript lodash library. There is a simple method _.mapKeys(object, [iteratee=_.identity]) that can do the conversion.

I have written code that sniffs IE4 or greater and is currently functioning perfectly in sites for my company's clients, as well as my own personal sites.

Include the following enumerated constant and function variables into a javascript include file on your page...

//methods
var BrowserTypes = {
    Unknown: 0,
    FireFox: 1,
    Chrome: 2,
    Safari: 3,
    IE: 4,
    IE7: 5,
    IE8: 6,
    IE9: 7,
    IE10: 8,
    IE11: 8,
    IE12: 8
};

var Browser = function () {
    try {
        //declares
        var type;
        var version;
        var sVersion;

        //process
        switch (navigator.appName.toLowerCase()) {
            case "microsoft internet explorer":
                type = BrowserTypes.IE;
                sVersion = navigator.appVersion.substring(navigator.appVersion.indexOf('MSIE') + 5, navigator.appVersion.length);
                version = parseFloat(sVersion.split(";")[0]);
                switch (parseInt(version)) {
                    case 7:
                        type = BrowserTypes.IE7;
                        break;
                    case 8:
                        type = BrowserTypes.IE8;
                        break;
                    case 9:
                        type = BrowserTypes.IE9;
                        break;
                    case 10:
                        type = BrowserTypes.IE10;
                        break;
                    case 11:
                        type = BrowserTypes.IE11;
                        break;
                    case 12:
                        type = BrowserTypes.IE12;
                        break;
                }
                break;
            case "netscape":
                if (navigator.userAgent.toLowerCase().indexOf("chrome") > -1) { type = BrowserTypes.Chrome; }
                else { if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) { type = BrowserTypes.FireFox } };
                break;
            default:
                type = BrowserTypes.Unknown;
                break;
        }

        //returns
        return type;
    } catch (ex) {
    }
};

Then all you have to do is use any conditional functionality such as...

ie. value = (Browser() >= BrowserTypes.IE) ? node.text : node.textContent;

or WindowWidth = (((Browser() >= BrowserTypes.IE9) || (Browser() < BrowserTypes.IE)) ? window.innerWidth : document.documentElement.clientWidth);

or sJSON = (Browser() >= BrowserTypes.IE) ? xmlElement.text : xmlElement.textContent;

Get the idea? Hope this helps.

Oh, you might want to keep it in mind to QA the Browser() function after IE10 is released, just to verify they didn't change the rules.

parse_cols is deprecated, use usecols instead

that is:

df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")

These are the vendor-prefixed properties offered by the relevant rendering engines (-webkit for Chrome, Safari; -moz for Firefox, -o for Opera, -ms for Internet Explorer). Typically they're used to implement new, or proprietary CSS features, prior to final clarification/definition by the W3.

This allows properties to be set specific to each individual browser/rendering engine in order for inconsistencies between implementations to be safely accounted for. The prefixes will, over time, be removed (at least in theory) as the unprefixed, the final version, of the property is implemented in that browser.

To that end it's usually considered good practice to specify the vendor-prefixed version first and then the non-prefixed version, in order that the non-prefixed property will override the vendor-prefixed property-settings once it's implemented; for example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Specifically, to address the CSS in your question, the lines you quote:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;
-moz-column-count: 3;
-moz-column-gap: 10px;
-moz-column-fill: auto;

Specify the column-count, column-gap and column-fill properties for Webkit browsers and Firefox.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Swift 4.2 solution (taking 4.0 answer and updating for new enums to compile)

extension UIView {
    func fadeTransition(_ duration:CFTimeInterval) {
        let animation = CATransition()
        animation.timingFunction = CAMediaTimingFunction(name:
            CAMediaTimingFunctionName.easeInEaseOut)
        animation.type = CATransitionType.fade
        animation.duration = duration
        layer.add(animation, forKey: CATransitionType.fade.rawValue)
    }
}

func updateLabel() {
myLabel.fadeTransition(0.4)
myLabel.text = "Hello World"
}

To add a star use the Unicode character 22C6.

I added a space to make a little gap between the li and the star. The code for space is A0.

li:before {
    content: '\22C6\A0';
}

You should look at the source of the HashSet constructor it calls... it's a special constructor that makes the backing Map a LinkedHashMap instead of just a HashMap.

You can use the dplyr package to easily remove those particular rows.

library(dplyr)
df <- filter(df, C != "Foo")

I've solved this error by this way.

$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, 'http://www.someurl/' );
curl_setopt ( $ch, CURLOPT_TIMEOUT, 30);
ob_start();
$response = curl_exec ( $ch );
$data = ob_get_clean();
if(curl_getinfo($ch, CURLINFO_HTTP_CODE) == 200 ) success;

Error still occurs, but I can handle response data in variable.

You can use remote js debugly option from your device or you can simply use react-native log-android and react-native log-ios for ios.

sort_mixed

Object.defineProperty(Array.prototype,"sort_mixed",{
    value: function () { // do not use arrow function
        var N = [], L = [];
        this.forEach(e => {
            Number.isFinite(e) ? N.push(e) : L.push(e);
        });
        N.sort((a, b) => a - b);
        L.sort();
        [...N, ...L].forEach((v, i) => this[i] = v);
        return this;
    })

try a =[1,'u',"V",10,4,"c","A"].sort_mixed(); console.log(a)

You can also use, if you want to preserve exit error status, and have a readable file with one command per line:

my_command1 || exit $?
my_command2 || exit $?

This, however will not print any additional error message. But in some cases, the error will be printed by the failed command anyway.

If the adapter is already set, setting it again will not refresh the listview. Instead first check if the listview has a adapter and then call the appropriate method.

I think its not a very good idea to create a new instance of the adapter while setting the list view. Instead, create an object.

BuildingAdapter adapter = new BuildingAdapter(context);

    if(getListView().getAdapter() == null){ //Adapter not set yet.
     setListAdapter(adapter);
    }
    else{ //Already has an adapter
    adapter.notifyDataSetChanged();
    }

Also you might try to run the refresh list on UI Thread:

activity.runOnUiThread(new Runnable() {         
        public void run() {
              //do your modifications here

              // for example    
              adapter.add(new Object());
              adapter.notifyDataSetChanged()  
        }
});

As of Rails 5, it is recommended to put the lib folder under app directory or instead create other meaningful name spaces for the folder as services , presenters, features etc and put it under app directory for auto loading by rails.

I use File -> Switch Workspace -> Other... and type in my new workspace name.

(EDIT: Added the composite screen shot.)

Once in the new workspace, File -> Import... and under General choose "Existing Projects into Workspace. Press the Next button and then Browse for the old projects you would like to import. Check "Copy projects into workspace" to make a copy.

Python has a keyboard module with many features. Install it, perhaps with this command:

pip3 install keyboard

Then use it in code like:

import keyboard  # using module keyboard
while True:  # making a loop
    try:  # used try so that if user pressed other than the given key error will not be shown
        if keyboard.is_pressed('q'):  # if key 'q' is pressed 
            print('You Pressed A Key!')
            break  # finishing the loop
    except:
        break  # if user pressed a key other than the given key the loop will break

Here is another way:

//Acsending
case "SUP_APPROVED_IND": qry =
                            qry.OrderBy(r => r.SUP_APPROVED_IND.Trim() == null).
                                    ThenBy(r => r.SUP_APPROVED_IND);

                            break;
//….
//Descending
case "SUP_APPROVED_IND": qry =
                            qry.OrderBy(r => r.SUP_APPROVED_IND.Trim() == null).
                                    ThenByDescending(r => r.SUP_APPROVED_IND); 

                            break;

SUP_APPROVED_IND is char(1) in Oracle db.

Note that r.SUP_APPROVED_IND.Trim() == null is treated as trim(SUP_APPROVED_IND) is null in Oracle db.

See this for details: How can i query for null values in entity framework?

Try this its working..

    <script>
      $(function () {
          $('form').on('submit', function (e) {
              e.preventDefault();
              $.ajax({
                  type: 'post',
                  url: '<?php echo base_url();?>student_ajax/insert',
                  data: $('form').serialize(),
                  success: function (response) {
                      alert('form was submitted');
                  }
                  error:function() {
                      alert('fail');
                  }
              });
          });
      });
    </script>

You just need to divide each element by the sum of the values in its column.

Doing this should suffice:

data.perc <- apply(data, 2, function(x){x/sum(x)})

Note that the second parameter tells apply to apply the provided function to columns (using 1 you would apply it to rows). The anonymous function, then, gets passed each data column, one at a time.

You can make api calls by choosing the HTTP method and setting optional parameters:

$facebook->api('/me/feed/', 'post', array(
    'message' => 'I want to display this message on my wall'
));

Submit Post to Facebook Wall :

Include the fbConfig.php file to connect Facebook API and get the access token.

Post message, name, link, description, and the picture will be submitted to Facebook wall. Post submission status will be shown.

If FB access token ($accessToken) is not available, the Facebook Login URL will be generated and the user would be redirected to the FB login page.

Post to facebook wall php sdk

<?php
//Include FB config file
require_once 'fbConfig.php';

if(isset($accessToken)){
    if(isset($_SESSION['facebook_access_token'])){
        $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
    }else{
        // Put short-lived access token in session
        $_SESSION['facebook_access_token'] = (string) $accessToken;

        // OAuth 2.0 client handler helps to manage access tokens
        $oAuth2Client = $fb->getOAuth2Client();

        // Exchanges a short-lived access token for a long-lived one
        $longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
        $_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;

        // Set default access token to be used in script
        $fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
    }

    //FB post content
    $message = 'Test message from CodexWorld.com website';
    $title = 'Post From Website';
    $link = 'http://www.codexworld.com/';
    $description = 'CodexWorld is a programming blog.';
    $picture = 'http://www.codexworld.com/wp-content/uploads/2015/12/www-codexworld-com-programming-blog.png';

    $attachment = array(
        'message' => $message,
        'name' => $title,
        'link' => $link,
        'description' => $description,
        'picture'=>$picture,
    );

    try{
        //Post to Facebook
        $fb->post('/me/feed', $attachment, $accessToken);

        //Display post submission status
        echo 'The post was submitted successfully to Facebook timeline.';
    }catch(FacebookResponseException $e){
        echo 'Graph returned an error: ' . $e->getMessage();
        exit;
    }catch(FacebookSDKException $e){
        echo 'Facebook SDK returned an error: ' . $e->getMessage();
        exit;
    }
}else{
    //Get FB login URL
    $fbLoginURL = $helper->getLoginUrl($redirectURL, $fbPermissions);

    //Redirect to FB login
    header("Location:".$fbLoginURL);
}

The following commands rename the branch locally, delete the old branch on the remote location and push the new branch, setting the local branch to track the new remote:

git branch -m old_branch new_branch
git push origin :old_branch
git push --set-upstream origin new_branch

Here is an easy way with String output (I created a method to do this):

public static String (String input){
    String output = "";
    try {
        /* From ISO-8859-1 to UTF-8 */
        output = new String(input.getBytes("ISO-8859-1"), "UTF-8");
        /* From UTF-8 to ISO-8859-1 */
        output = new String(input.getBytes("UTF-8"), "ISO-8859-1");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return output;
}
// Example
input = "Música";
output = "Música";

ulimit -s unlimited lets the stack grow unlimited.

This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.

I had this problem and I was able to fix this by updating npm

sudo npm update -g npm

Before the update, the result of npm info graceful-fs | grep 'version:' was:

version: '3.3.12'

After the update the result is:

version: '3.9.3'

If you want exact results and speed, try gmpy -- gmpy.comb should do exactly what you ask for, and it's pretty fast (of course, as gmpy's original author, I am biased;-).

Here is a solution I made using the above ideas that can be used for TextBoxFor and PasswordFor:

public static class HtmlHelperEx
{
    public static MvcHtmlString TextBoxWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.TextBoxFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }

    public static MvcHtmlString PasswordWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.PasswordFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }
}

public static class HtmlAttributesHelper
{
    public static IDictionary<string, object> AddAttribute(this object htmlAttributes, string name, object value)
    {
        var dictionary = htmlAttributes == null ? new Dictionary<string, object>() : htmlAttributes.ToDictionary();
        if (!String.IsNullOrWhiteSpace(name) && value != null && !String.IsNullOrWhiteSpace(value.ToString()))
            dictionary.Add(name, value);
        return dictionary;
    }

    public static IDictionary<string, object> ToDictionary(this object obj)
    {
        return TypeDescriptor.GetProperties(obj)
            .Cast<PropertyDescriptor>()
            .ToDictionary(property => property.Name, property => property.GetValue(obj));
    }
}

To get the current directory, you can use this:

CD > tmpFile
SET /p myvar= < tmpFile
DEL tmpFile
echo test: %myvar%

It's using a temp-file though, so it's not the most pretty, but it certainly works! 'CD' puts the current directory in 'tmpFile', 'SET' loads the content of tmpFile.

Here is a solution for multiple lines with "array's":

@echo off

rem ---------
rem Obtain line numbers from the file
rem ---------

rem This is the file that is being read: You can replace this with %1 for dynamic behaviour or replace it with some command like the first example i gave with the 'CD' command.
set _readfile=test.txt

for /f "usebackq tokens=2 delims=:" %%a in (`find /c /v "" %_readfile%`) do set _max=%%a
set /a _max+=1
set _i=0
set _filename=temp.dat

rem ---------
rem Make the list
rem ---------

:makeList
find /n /v "" %_readfile% >%_filename%

rem ---------
rem Read the list
rem ---------

:readList
if %_i%==%_max% goto printList

rem ---------
rem Read the lines into the array
rem ---------
for /f "usebackq delims=] tokens=2" %%a in (`findstr /r "\[%_i%]" %_filename%`) do set _data%_i%=%%a
set /a _i+=1
goto readList

:printList
del %_filename%
set _i=1
:printMore
if %_i%==%_max% goto finished
set _data%_i%
set /a _i+=1
goto printMore

:finished

But you might want to consider moving to another more powerful shell or create an application for this stuff. It's stretching the possibilities of the batch files quite a bit.

Aghhh... i was missing some code when i first tried the .submit function.....

This works:

$('#create-card-process.design').submit(function() {
    var textStyleCSS = $("#cover-text").attr('style');
    var textbackgroundCSS = $("#cover-text-wrapper").attr('style');
    $("#cover_text_css").val(textStyleCSS);
    $("#cover_text_background_css").val(textbackgroundCSS);
});

Thanks for all the comments.

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

You can use the non-standard FROM clause.

UPDATE b
SET column1 = a.column1,
  column2 = a.column2,
  column3 = a.column3
FROM a
WHERE a.id = b.id
AND b.id = 1

Here is how you can create a rounded rectangle with SVG Path:

<path d="M100,100 h200 a20,20 0 0 1 20,20 v200 a20,20 0 0 1 -20,20 h-200 a20,20 0 0 1 -20,-20 v-200 a20,20 0 0 1 20,-20 z" />

Explanation

m100,100: move to point(100,100)

h200: draw a 200px horizontal line from where we are

a20,20 0 0 1 20,20: draw an arc with 20px X radius, 20px Y radius, clockwise, to a point with 20px difference in X and Y axis

v200: draw a 200px vertical line from where we are

a20,20 0 0 1 -20,20: draw an arc with 20px X and Y radius, clockwise, to a point with -20px difference in X and 20px difference in Y axis

h-200: draw a -200px horizontal line from where we are

a20,20 0 0 1 -20,-20: draw an arc with 20px X and Y radius, clockwise, to a point with -20px difference in X and -20px difference in Y axis

v-200: draw a -200px vertical line from where we are

a20,20 0 0 1 20,-20: draw an arc with 20px X and Y radius, clockwise, to a point with 20px difference in X and -20px difference in Y axis

z: close the path

<svg width="440" height="440">_x000D_
  <path d="M100,100 h200 a20,20 0 0 1 20,20 v200 a20,20 0 0 1 -20,20 h-200 a20,20 0 0 1 -20,-20 v-200 a20,20 0 0 1 20,-20 z" fill="none" stroke="black" stroke-width="3" />_x000D_
</svg>

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

May I propose a third

((Integer) a).compareTo(b)  

You can reorder the operands:

$null -eq $foo

Note that -eq in PowerShell is not an equivalence relation.

Use:

dqote='"'
sqote="'"

Use the '+' operator and dqote and squote variables to get what you need.

If I want sed -e s/",u'"/",'"/g -e s/^"u'"/"'"/, you can try the following:

dqote='"'
sqote="'"
cmd1="sed -e s/" + dqote + ",u'" + dqote + "/" + dqote + ",'" + dqote + '/g -e s/^"u' + sqote + dqote + '/' + dqote + sqote + dqote + '/'

There are many ways. Here are at least five:

If you want to match anything after a word stop an not only at the start of the line you may use : \bstop.*\b - word followed by line

Or if you want to match the word in the string use \bstop[a-zA-Z]* - only the words starting with stop

Or the start of lines with stop ^stop[a-zA-Z]* for the word only - first word only
The whole line ^stop.* - first line of the string only

And if you want to match every string starting with stop including newlines use : /^stop.*/s - multiline string starting with stop

You can get the list of subdirectories (and files) in Python 2.7 using os.listdir(path)

import os
os.listdir(path)  # list of subdirectories and files

Android Studio takes source version equal to Target Version in your application. Compilation performed with source version equal to above mentioned Compile Version. So, take care that in your project Compile Version == Target Version (adjust module's build.gradle file).

Google lead me here while searching on the same question phill asked (sorting floats) so I figured it would be worth posting the answer despite the thread being kind of old. I'm new to perl and am still getting my head wrapped around it but brian d foy's statement "Perl cares more about the verbs than it does the nouns." above really hits the nail on the head. You don't need to convert the strings to floats before applying the sort. You need to tell the sort to sort the values as numbers and not strings. i.e.

my @foo = ('1.2', '3.4', '2.1', '4.6');
my @foo_sort = sort {$a <=> $b} @foo;

See http://perldoc.perl.org/functions/sort.html for more details on sort

I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.

I assume it was something to do with iostream manipulations in the constructor.

Here is the fix:

// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
    cout << "Some text I was printing.." << endl;
};


// After
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {

};

Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.

The following example defines a Button1_Click event handler. When invoked, this handler uses the FindControl method to locate a control with an ID property of TextBox2 on the containing page. If the control is found, its parent is determined using the Parent property and the parent control's ID is written to the page. If TextBox2 is not found, "Control Not Found" is written to the page.

private void Button1_Click(object sender, EventArgs MyEventArgs)
{
      // Find control on page.
      Control myControl1 = FindControl("TextBox2");
      if(myControl1!=null)
      {
         // Get control's parent.
         Control myControl2 = myControl1.Parent;
         Response.Write("Parent of the text box is : " + myControl2.ID);
      }
      else
      {
         Response.Write("Control not found");
      }
}

Active Directory is a super-set of the LDAP protocol. Depending on how the organization uses Active Directory, your LDAP search/set queries may or may not work.

You must add this code in your Service class so that it handles the case when your process is being killed

 @Override
    public void onTaskRemoved(Intent rootIntent) {
        Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
        restartServiceIntent.setPackage(getPackageName());

        PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
        AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
        alarmService.set(
                AlarmManager.ELAPSED_REALTIME,
                SystemClock.elapsedRealtime() + 1000,
                restartServicePendingIntent);

        super.onTaskRemoved(rootIntent);
    }

Probably u might be using a incorrect SDK version. Right click on your project. Select Properties-->Android. Note that 2.2 is the latest SDK. Check it and see if it gets compiled...

Edit

Also Do a clean after that

my_function.func_name

There are also other fun properties of functions. Type dir(func_name) to list them. func_name.func_code.co_code is the compiled function, stored as a string.

import dis
dis.dis(my_function)

will display the code in almost human readable format. :)

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

I know it has been a long time since the original question was posted. But i think for slow ones like me a bit of explanation of @Heisenberg's answer would help.

Declare two variable in the adapter class as

private int mExpandedPosition= -1;
private RecyclerView recyclerView = null;

Then in onBindViewHolder following as given in the original answer.

      // This line checks if the item displayed on screen 
      // was expanded or not (Remembering the fact that Recycler View )
      // reuses views so onBindViewHolder will be called for all
      // items visible on screen.
    final boolean isExpanded = position==mExpandedPosition;

        //This line hides or shows the layout in question
        holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);

        // I do not know what the heck this is :)
        holder.itemView.setActivated(isExpanded);

        // Click event for each item (itemView is an in-built variable of holder class)
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

 // if the clicked item is already expaned then return -1 
//else return the position (this works with notifyDatasetchanged )
                mExpandedPosition = isExpanded ? -1:position;
    // fancy animations can skip if like
                TransitionManager.beginDelayedTransition(recyclerView);
    //This will call the onBindViewHolder for all the itemViews on Screen
                notifyDataSetChanged();
            }
        });

And lastly to get the recyclerView object in the adapter override

@Override
public void onAttachedToRecyclerView(@NonNull RecyclerView recyclerView) {
    super.onAttachedToRecyclerView(recyclerView);

    this.recyclerView = recyclerView;
}

Hope this Helps.

Since String objects are immutable, going to a char[] via toCharArray, swapping the characters, then making a new String from char[] via the String(char[]) constructor would work.

The following example swaps the first and second characters:

String originalString = "abcde";

char[] c = originalString.toCharArray();

// Replace with a "swap" function, if desired:
char temp = c[0];
c[0] = c[1];
c[1] = temp;

String swappedString = new String(c);

System.out.println(originalString);
System.out.println(swappedString);

Result:

abcde
bacde

JSON doesn't allow breaking lines for readability.

Your best bet is to use an IDE that will line-wrap for you.

CryptoSwift is very interesting project but for now it has some AES speed limitations. Be carefull if you need to do some serious crypto - it might be worth to go through the pain of bridge implemmenting CommonCrypto.

BigUps to Marcin for pureSwift implementation

With Sequel Pro:

Restarting the app unlocked my tables. It resets the session connection.

NOTE: I was doing this for a site on my local machine.

It is useful when you share a variable between a few modules. You define it in one module, and use extern in the others.

For example:

in file1.cpp:

int global_int = 1;

in file2.cpp:

extern int global_int;
//in some function
cout << "global_int = " << global_int;

I believe that you will have to drop the foreign key constraints first. Then update all of the appropriate tables and remap them as they were.

ALTER TABLE [dbo.Details_tbl] DROP CONSTRAINT [FK_Details_tbl_User_tbl];
-- Perform more appropriate alters
ALTER TABLE [dbo.Details_tbl] ADD FOREIGN KEY (FK_Details_tbl_User_tbl) 
    REFERENCES User_tbl(appId);
-- Perform all appropriate alters to bring the key constraints back

However, unless memory is a really big issue, I would keep the identity as an INT. Unless you are 100% positive that your keys will never grow past the TINYINT restraints. Just a word of caution :)

In your Log4net config file, use the following parameter with the RollingFileAppender:

<param name="DatePattern" value="dd.MM.yyyy'.log'" />

In XCode 10.1, I had to set "Library Search Paths" to something like $(PROJECT_DIR)/.../path/to/your/library

You should use ToList() method. (Don't forget about System.Linq namespace)

ex.:

IList<Model> models = Builder<Model>.CreateListOfSize(10).Build();
List<Model> lstMOdels = models.ToList();

I feel your pain. I've tried every answer above, including the setIncludeFontPadding to false, which did nothing for me.

My solution? layout_marginBottom="-3dp" on the TextView gives you a solution for the bottom, BAM!

Although, -3dp on layout_marginTop fails....ugh.

Accordingly to W3C checked input's attribute can be absent/ommited or have "checked" as its value. This does not invalidate other values because there's no restriction to the browser implementation to allow values like "true", "on", "yes" and so on. To guarantee that you'll write a cross-browser checkbox/radio use checked="checked", as recommended by W3C.

disabled, readonly and ismap input's attributes go on the same way.

EDITED

empty is not a valid value for checked, disabled, readonly and ismap input's attributes, as warned by @Quentin

Yes you can (this is how I understand the original question). Here is how I did it. Just tie it into outside context. For example:

//javascript

my_function = null;

//jquery 
 $(function() { 

        function my_fun(){ 
               /.. some operations ../ 
        }  
        my_function = my_fun;
 }) 

 //just js 
 function js_fun () {  
       my_function(); //== call jquery function - just Reference is globally defined not function itself
}

I encountered this same problem when trying to access methods of the object, that was instantiated on DOM object ready only. Works. My example:

MyControl.prototype = {
   init:   function { 
        // init something
   }
   update: function () {
           // something useful, like updating the list items of control or etc.         
   }
}

MyCtrl = null;

// create jquery plug-in
$.fn.aControl = function () {
    var control = new MyControl(this);
    control.init();
    MyCtrl = control; // here is the trick
    return control;
}

now you can use something simple like:

function() = {
   MyCtrl.update(); // yes!
}

My contribution with a Swift extension:

extension UIView {
    func asCircle() {
        self.layer.cornerRadius = self.frame.width / 2;
        self.layer.masksToBounds = true
    }
}

Just call myView.asCircle()

You can try this:

$('.show_hide').click(function () {
    $(".slidingDiv").toggle("'slide', {direction: 'right' }, 1000");
});

In mathematics, I think the dot in numpy makes more sense

dot(a,b)_{i,j,k,a,b,c} =

since it gives the dot product when a and b are vectors, or the matrix multiplication when a and b are matrices

As for matmul operation in numpy, it consists of parts of dot result, and it can be defined as

>matmul(a,b)_{i,j,k,c} =

So, you can see that matmul(a,b) returns an array with a small shape, which has smaller memory consumption and make more sense in applications. In particular, combining with broadcasting, you can get

matmul(a,b)_{i,j,k,l} =

for example.

From the above two definitions, you can see the requirements to use those two operations. Assume a.shape=(s1,s2,s3,s4) and b.shape=(t1,t2,t3,t4)

• To use dot(a,b) you need

  1. t3=s4;

• To use matmul(a,b) you need

  1. t3=s4
  2. t2=s2, or one of t2 and s2 is 1
  3. t1=s1, or one of t1 and s1 is 1

Use the following piece of code to convince yourself.

Code sample

import numpy as np
for it in xrange(10000):
    a = np.random.rand(5,6,2,4)
    b = np.random.rand(6,4,3)
    c = np.matmul(a,b)
    d = np.dot(a,b)
    #print 'c shape: ', c.shape,'d shape:', d.shape

    for i in range(5):
        for j in range(6):
            for k in range(2):
                for l in range(3):
                    if not c[i,j,k,l] == d[i,j,k,j,l]:
                        print it,i,j,k,l,c[i,j,k,l]==d[i,j,k,j,l] #you will not see them

UTF-8 has an advantage in the case where ASCII characters represent the majority of characters in a block of text, because UTF-8 encodes these into 8 bits (like ASCII). It is also advantageous in that a UTF-8 file containing only ASCII characters has the same encoding as an ASCII file.

UTF-16 is better where ASCII is not predominant, since it uses 2 bytes per character, primarily. UTF-8 will start to use 3 or more bytes for the higher order characters where UTF-16 remains at just 2 bytes for most characters.

UTF-32 will cover all possible characters in 4 bytes. This makes it pretty bloated. I can't think of any advantage to using it.

You may use Directory Functions: http://php.net/manual/en/book.dir.php

Simple example from opendir() function description:

<?php
$dir_path = "/path/to/your/dir";

if (is_dir($dir_path)) {
    if ($dir_handler = opendir($dir_path)) {
        while (($file = readdir($dir_handler)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir_path . $file) . "\n";
        }
        closedir($dir_handler);
    }
}
?>

I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.

Here's the pypi https://pypi.python.org/pypi/cx_Freeze

The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html

I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.

How do I use cx_freeze?

For those who have updated to the latest version of google-play-services_lib and/or have this error Google Play services out of date. Requires 3136100 but found 2012110 this newer version of com.google.android.gms.apk (Google Play Services 3.1.36) and com.android.vending.apk (Google Play Store 4.1.6) should work.

Test with this configuration on Android SDK Tools 22.0.1. Another configuration that targets pure Android, not the Google one, should work too.

• Device: Galaxy Nexus
• Target: Android 4.2.2 - API Level 17
• CPU/ABI: ARM (armeabi-v7a)
• Checked: Use Host GPU

...

1. Open the AVD

2. Execute this in the terminal / cmd

   adb -e install com.google.android.gms.apk
   adb -e install com.android.vending.apk
   

3. Restart the AVD

4. Have fun coding!!!

I found this way to be the easiest, cleanest and it works with the newest version of the software, which allow you to get all the bug fixes.

Other way to check if a URL is valid or not can be:

<?php

  if (isValidURL("http://www.gimepix.com")) {
      echo "URL is valid...";
  } else {
      echo "URL is not valid...";
  }

  function isValidURL($url) {
      $file_headers = @get_headers($url);
      if (strpos($file_headers[0], "200 OK") > 0) {
         return true;
      } else {
        return false;
      }
  }
?>

Please don't use this recipe if your situation is not the one described in the question. This recipe is for fixing a bad merge, and replaying your good commits onto a fixed merge.

Although filter-branch will do what you want, it is quite a complex command and I would probably choose to do this with git rebase. It's probably a personal preference. filter-branch can do it in a single, slightly more complex command, whereas the rebase solution is performing the equivalent logical operations one step at a time.

Try the following recipe:

# create and check out a temporary branch at the location of the bad merge
git checkout -b tmpfix <sha1-of-merge>

# remove the incorrectly added file
git rm somefile.orig

# commit the amended merge
git commit --amend

# go back to the master branch
git checkout master

# replant the master branch onto the corrected merge
git rebase tmpfix

# delete the temporary branch
git branch -d tmpfix

(Note that you don't actually need a temporary branch, you can do this with a 'detached HEAD', but you need to take a note of the commit id generated by the git commit --amend step to supply to the git rebase command rather than using the temporary branch name.)

Once you've upgraded to PowerShell version 5 you can get the startup type.

To check the version of PowerShell you're running, use $PSVersionTable.

The examples below are for the Windows Firewall Service:

For the local system

Get-Service | Select-Object -Property Name,Status,StartType | where-object {$_.Name -eq "MpsSvc"} | Format-Table -auto

For one remote system

Get-Service -ComputerName HOSTNAME_OF_SYSTEM | Select-Object -Property MachineName,Name,Status,StartType | where-object {$_.Name -eq "MpsSvc"} | Format-Table -auto

For multiple systems (must create the systems.txt)

Get-Service -ComputerName (Get-content c:\systems.txt) | Select-Object -Property MachineName,Name,Status,StartType | where-object {$_.Name -eq "MpsSvc"} | Format-Table -auto

I too was stuck on this problem for too long.

I required a solution that worked for versions both above and below v21.

I finally discovered a very simple perhaps not ideal but effective solution: Simply set the background colour to transparent in the EditText properties.

<EditText
    android:background="@android:color/transparent"/>

I hope this saves someone some time.

if you have array that looks like this -

data = [["foo",1,2,3,4],["bar",1,2],["foobar",1,"*",3,5,:foo]]

and you want the first elements of each array to become the keys for the hash and the rest of the elements becoming value arrays, then you can do something like this -

data_hash = Hash[data.map { |key| [key.shift, key] }]

#=>{"foo"=>[1, 2, 3, 4], "bar"=>[1, 2], "foobar"=>[1, "*", 3, 5, :foo]}

here is my methods, it is a little bit convince that number of bytes fixed

private void printByte(int value) {
String currentBinary = Integer.toBinaryString(256 + value);
System.out.println(currentBinary.substring(currentBinary.length() - 8));
}

public int binaryToInteger(String binary) {
char[] numbers = binary.toCharArray();
int result = 0;
for(int i=numbers.length - 1; i>=0; i--)
  if(numbers[i]=='1')
    result += Math.pow(2, (numbers.length-i - 1));
return result;
}

you have to open a port of the service in you router then try you puplic ip out of your all network cause if you try it from your network , the puplic ip will always redirect you to your router but from the outside it will redirect to the server you have

You don't want to delete if you're wanting to leave the row itself intact. You want to update the row, and change the column value.

The general form for this would be an UPDATE statement:

UPDATE <table name>
SET
    ColumnA = <NULL, or '', or whatever else is suitable for the new value for the column>
WHERE
    ColumnA = <bad value> /* or any other search conditions */

Linux: who am i | awk '{print $5}' | sed 's/[()]//g'

AIX: who am i | awk '{print $6}' | sed 's/[()]//g'

If the longValue variable is of type Long (the wrapper class, not the primitive long), then yes you can check for null values.

A primitive variable needs to be initialized to some value explicitly (e.g. to 0) so its value will never be null.

for android API byte[] to Base64String encoder

byte[] data=new byte[];
String Base64encodeString=android.util.Base64.encodeToString(data, android.util.Base64.DEFAULT);

With this code you can obtain any controller:

var controller = DependencyResolver.Current.GetService<ControllerB>();
controller.ControllerContext = new ControllerContext(this.Request.RequestContext, 
controller);

There are two operators for type testing: E is T tests for E an instance of type T while E is! T tests for E not an instance of type T.

Note that E is Object is always true, and null is T is always false unless T===Object.

After adding php directory in User Settings,

{
    "php.validate.executablePath": "C:/phpdirectory/php7.1.8/php.exe",
    "php.executablePath": "C:/phpdirectory/php7.1.8/php.exe"
}

If you still have this error, please verify you have installed :

• 64-bit or 32-bit version of php (x64 or x86), depending on your OS;

• some librairies like Visual C++ Redistributable for Visual Studio 2015 : http://www.microsoft.com/en-us/download/details.aspx?id=48145;

To test if you PHP exe is ok, open cmd.exe :

c:/prog/php-7.1.8-Win32-VC14-x64/php.exe --version

If PHP fails, a message will be prompted with the error (missing dll for example).

Using json lib:-

String data="[{"A":"a","B":"b","C":"c","D":"d","E":"e","F":"f","G":"g"}]";
Object object=null;
JSONArray arrayObj=null;
JSONParser jsonParser=new JSONParser();
object=jsonParser.parse(data);
arrayObj=(JSONArray) object;
System.out.println("Json object :: "+arrayObj);

Using GSON lib:-

Gson gson = new Gson();

JsonParser jsonParser = new JsonParser();
JsonArray jsonArray = (JsonArray) jsonParser.parse(data);

For your actual form, if you were to just post the results to your same page, it should probably work out all right. Try something like:

<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> method="POST>

array_walk() can be used with trim() to trim array

<?php
function trim_value(&$value) 
{ 
    $value = trim($value); 
}

$fruit = array('apple','banana ', ' cranberry ');
var_dump($fruit);

array_walk($fruit, 'trim_value');
var_dump($fruit);

?>

See 2nd example at http://www.php.net/manual/en/function.trim.php

I had the same issue and I solved it by using:

display: inline-block;

on the div in question.

This allow submit every 2 seconds. In case of front validation.

$(document).ready(function() {
    $('form[debounce]').submit(function(e) {
        const submiting = !!$(this).data('submiting');

        if(!submiting) {
            $(this).data('submiting', true);

            setTimeout(() => {
                $(this).data('submiting', false);
            }, 2000);

            return true;
        }

        e.preventDefault();
        return false;
    });
})

Indeed this relies on the programmer's preferences. I personally use: numeric(15,4) to conform to the Generally Accepted Accounting Principles (GAAP).

HTTP Basic + HTTPS is one common method.

Since you are explicitly also asking to handle columns that haven't yet been filled out, and I assume also don't want to mess with them if they have a word instead of a number, you might consider this:

=If(IsNumber(K23), If(K23 > 0, ........., 0), 0)

This just says... If K23 is a number; And if that number is greater than zero; Then do something ......... Otherwise, return zero.

In ........., you might put your division equation there, such as A1/K23, and you can rest assured that K23 is a number which is greater than zero.

The simplest way to do this, if all you want is pinch zooming, is to place your image inside a UIWebView (write small amount of html wrapper code, reference your image, and you're basically done). The more complcated way to do this is to use touchesBegan, touchesMoved, and touchesEnded to keep track of the user's fingers, and adjust your view's transform property appropriately.

In the code below, Class A implements the interface IShow and implements its method ShowData. Class B inherits Class A. In order to use ShowData method in Class B, we have to use keyword new in the ShowData method in order to hide the base class Class A method and use override keyword in order to extend the method.

interface IShow
{
    protected void ShowData();
}

class A : IShow
{
    protected void ShowData()
    {
        Console.WriteLine("This is Class A");
    }
}

class B : A
{
    protected new void ShowData()
    {
        Console.WriteLine("This is Class B");
    }
}

Sohnee solutions is cleaner, but you can also try

window["bootbox"]

The easiest way to do this is to click on the Terminate button(red square) in the console:

What you'll see sometimes is the following:

class Abstract1( object ):
    """Some description that tells you it's abstract,
    often listing the methods you're expected to supply."""
    def aMethod( self ):
        raise NotImplementedError( "Should have implemented this" )

Because Python doesn't have (and doesn't need) a formal Interface contract, the Java-style distinction between abstraction and interface doesn't exist. If someone goes through the effort to define a formal interface, it will also be an abstract class. The only differences would be in the stated intent in the docstring.

And the difference between abstract and interface is a hairsplitting thing when you have duck typing.

Java uses interfaces because it doesn't have multiple inheritance.

Because Python has multiple inheritance, you may also see something like this

class SomeAbstraction( object ):
    pass # lots of stuff - but missing something

class Mixin1( object ):
    def something( self ):
        pass # one implementation

class Mixin2( object ):
    def something( self ):
        pass # another

class Concrete1( SomeAbstraction, Mixin1 ):
    pass

class Concrete2( SomeAbstraction, Mixin2 ):
    pass

This uses a kind of abstract superclass with mixins to create concrete subclasses that are disjoint.

" is on the official list of valid HTML 4 entities, but ' is not.

From C.16. The Named Character Reference ':

The named character reference ' (the apostrophe, U+0027) was introduced in XML 1.0 but does not appear in HTML. Authors should therefore use ' instead of ' to work as expected in HTML 4 user agents.

It is incredible that there are so many answers but none answers the question:

"When I was asking this question, I asked for a way of opening a UTF-8 CSV file in Excel without any problems for a user,..."

The answer marked as the accepted answer with 200+ up-votes is useless for me because I don't want to give my users a manual how to configure Excel. Apart from that: this manual will apply to one Excel version but other Excel versions have different menus and configuration dialogs. You would need a manual for each Excel version.

So the question is how to make Excel show UTF8 data with a simple double click?

Well at least in Excel 2007 this is not possible if you use CSV files because the UTF8 BOM is ignored and you will see only garbage. This is already part of the question of Lyubomyr Shaydariv:

"I also tried specifying UTF-8 BOM EF BB BF, but Excel ignores that."

I make the same experience: Writing russian or greek data into a UTF8 CSV file with BOM results in garbage in Excel:

Content of UTF8 CSV file:

Colum1;Column2
Val1;Val2
?????????;T??????

Result in Excel 2007:

A solution is to not use CSV at all. This format is implemented so stupidly by Microsoft that it depends on the region settings in control panel if comma or semicolon is used as separator. So the same CSV file may open correctly on one computer but on anther computer not. "CSV" means "Comma Separated Values" but for example on a german Windows by default semicolon must be used as separator while comma does not work. (Here it should be named SSV = Semicolon Separated Values) CSV files cannot be interchanged between different language versions of Windows. This is an additional problem to the UTF-8 problem.

Excel exists since decades. It is a shame that Microsoft was not able to implement such a basic thing as CSV import in all these years.

However, if you put the same values into a HTML file and save that file as UTF8 file with BOM with the file extension XLS you will get the correct result.

Content of UTF8 XLS file:

<table>
<tr><td>Colum1</td><td>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td>?????????</td><td>T??????</td></tr>
</table>

Result in Excel 2007:

You can even use colors in HTML which Excel will show correctly.

<style>
.Head { background-color:gray; color:white; }
.Red  { color:red; }
</style>
<table border=1>
<tr><td class=Head>Colum1</td><td class=Head>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td class=Red>?????????</td><td class=Red>T??????</td></tr>
</table>

Result in Excel 2007:

In this case only the table itself has a black border and lines. If you want ALL cells to display gridlines this is also possible in HTML:

<html xmlns:x="urn:schemas-microsoft-com:office:excel">
    <head>
        <meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>
        <xml>
            <x:ExcelWorkbook>
                <x:ExcelWorksheets>
                    <x:ExcelWorksheet>
                        <x:Name>MySuperSheet</x:Name>
                        <x:WorksheetOptions>
                            <x:DisplayGridlines/>
                        </x:WorksheetOptions>
                    </x:ExcelWorksheet>
                </x:ExcelWorksheets>
            </x:ExcelWorkbook>
        </xml>
    </head>
    <body>
        <table>
            <tr><td>Colum1</td><td>Column2</td></tr>
            <tr><td>Val1</td><td>Val2</td></tr>
            <tr><td>?????????</td><td>T??????</td></tr>
        </table>
    </body>
</html>

This code even allows to specify the name of the worksheet (here "MySuperSheet")

Result in Excel 2007:

The CSS for styling lists is here, but is basically:

li {
    list-style-type: decimal;
    list-style-position: inside;
}

However, the specific layout you're after can probably only be achieved by delving into the innards of the layout with something like this (note that I haven't actually tried it):

ol { counter-reset: item }
li { display: block }
li:before { content: counter(item) ") "; counter-increment: item }

2. Then in "Packages" view choose "Settings View".
3. Choose "Install Packages/Themes".
4. Search for "Atom Beautify" and install it.

Just enable parsing of the autoexec.bat in the registry, using these instructions.

A pull request is just that: a request to merge one branch into another.

Your pull request doesn't "contain" anything, it's just a marker saying "please merge this branch into that one".

The set of changes the PR shows in the web UI is just the changes between the target branch and your feature branch. To modify your pull request, you must modify your feature branch, probably with a force push to the feature branch.

In your case, you'll probably want to amend your commit. Not sure about your exact situation, but some combination of interactive rebase and add -p should sort you out.

You're using the default comparator to sort a Set<String>. In this case, that means lexicographic order. Lexicographically, "12" comes before "15", comes before "5".

Either use a Set<Integer>:

Set<Integer> set=new HashSet<Integer>();
set.add(12);
set.add(15);
set.add(5);

Or use a different comparator:

Collections.sort(list, new Comparator<String>() {
    public int compare(String a, String b) {
        return Integer.parseInt(a) - Integer.parseInt(b);
    }
});

Ok, so in this application, there is an iframe in which the user is supplied with links or some capacity that allows that iframe to browse to some external site. You are then looking to capture the URL to which the user has browsed.

Something to keep in mind. Since the URL is to an external source, you will be limited in how much you can interact with this iframe via javascript (or an client side access for that matter), this is known as browser cross-domain security, as apparently you have discovered. There are clever work arounds, as presented here Cross-domain, cross-frame Javascript, although I do not think this work around applies in this case.

About all you can access is the location, as you need.

I would suggest making the code presented more resilitant and less error prone. Try browsing the web sometime with IE or FF configured to show javascript errors. You will be surprised just how many javascript errors are thrown, largely because there is a lot of error prone javascript out there, which just continues to proliferate.

This solution assumes that the iframe in question is the same "window" context where you are running the javascript. (Meaning, it is not embedded within another frame or iframe, in which case, the javascript code gets more involved, and you likely need to recursively search through the window hierarchy.)

<iframe name='frmExternal' id='frmExternal' src='http://www.stackoverflow.com'></frame>
<input type='text' id='txtUrl' />
<input type='button' id='btnGetUrl' value='Get URL' onclick='GetIFrameUrl();' />

<script language='javascript' type='text/javascript'>
function GetIFrameUrl()
{
    if (!document.getElementById)
    {
        return;
    }

    var frm = document.getElementById("frmExternal");
    var txt = document.getElementById("txtUrl");

    if (frm == null || txt == null)
    {
        // not great user feedback but slightly better than obnoxious script errors
       alert("There was a problem with this page, please refresh.");
       return;
    }

    txt.value = frm.src;
}
</script>

Hope this helps.

I think the simplest way to build a model from an instance of ResultSet, could be as follows.

public static void main(String[] args) throws Exception {
    // The Connection is obtained

    ResultSet rs = stmt.executeQuery("select * from product_info");

    // It creates and displays the table
    JTable table = new JTable(buildTableModel(rs));

    // Closes the Connection

    JOptionPane.showMessageDialog(null, new JScrollPane(table));

}

The method buildTableModel:

public static DefaultTableModel buildTableModel(ResultSet rs)
        throws SQLException {

    ResultSetMetaData metaData = rs.getMetaData();

    // names of columns
    Vector<String> columnNames = new Vector<String>();
    int columnCount = metaData.getColumnCount();
    for (int column = 1; column <= columnCount; column++) {
        columnNames.add(metaData.getColumnName(column));
    }

    // data of the table
    Vector<Vector<Object>> data = new Vector<Vector<Object>>();
    while (rs.next()) {
        Vector<Object> vector = new Vector<Object>();
        for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++) {
            vector.add(rs.getObject(columnIndex));
        }
        data.add(vector);
    }

    return new DefaultTableModel(data, columnNames);

}

It works.

You can do this.
When hovering to the .item1, it will change the .item2 element.

.item1 {
  size:100%;
}

.item1:hover
{
   .item2 {
     border:none;
   }
}

.item2{
  border: solid 1px blue;
}

I'd probably use a LEFT JOIN, which will return rows even if there's no match, and then you can select only the rows with no match by checking for NULLs.

So, something like:

SELECT V.*
FROM voter V LEFT JOIN elimination E ON V.id = E.voter_id
WHERE E.voter_id IS NULL

Whether that's more or less efficient than using a subquery depends on optimization, indexes, whether its possible to have more than one elimination per voter, etc.

Beware of typos! I had the following

<TreeView ItemsSource="{Binding MyCollection}">
    <TreeView.Resources>
        ...
    </TreeView.Resouces>>
</TreeView>

(Notice the tailing >, which is interpreted as content, so you're setting twice the content... Took me a while :)

somehow and sometimes "terminfo" folder comes corrupted after a fresh installation. i don't know why, but the problem can be solved in this way:

1. Download Lion Installer from the App Store
2. Download unpkg: http://www.macupdate.com/app/mac/16357/unpkg
3. Open Lion Installer app in Finder (Right click -> Show Package
Contents)
4. Open InstallESD.dmg (under SharedSupport)
5. Unpack BSD.pkg with unpkg (Located under Packages)   Term info
will be located in the new BSD folder in /usr/share/terminfo

hope it helps.

Provided that you can use .NET 3.5 (or newer) and LINQ, try

int sum = arr.Sum();

I had the same problem with Firefox 30 + Selenium 2.49 + Ubuntu 15.04.

It worked fine with Ubuntu 14 but after upgrade to 15.04 I got same RANDR warning and problem at starting Firefox using Xfvb.

After adding +extension RANDR it worked again.

$ vim /etc/init/xvfb.conf

The "IIS APPPOOL\AppPoolName" will work, but as mentioned previously, it does not appear to be a valid AD name so when you search for it in the "Select User or Group" dialog box, it won't show up (actually, it will find it, but it will think its an actual system account, and it will try to treat it as such...which won't work, and will give you the error message about it not being found).

How I've gotten it to work is:

1. In SQL Server Management Studio, look for the Security folder (the security folder at the same level as the Databases, Server Objects, etc. folders...not the security folder within each individual database)
2. Right click logins and select "New Login"
3. In the Login name field, type IIS APPPOOL\YourAppPoolName - do not click search
4. Fill whatever other values you like (i.e., authentication type, default database, etc.)
5. Click OK

As long as the AppPool name actually exists, the login should now be created.

Does your upload die at the very end? 99% before crashing? Client body and buffers are key because nginx must buffer incoming data. The body configs (data of the request body) specify how nginx handles the bulk flow of binary data from multi-part-form clients into your app's logic.

The clean setting frees up memory and consumption limits by instructing nginx to store incoming buffer in a file and then clean this file later from disk by deleting it.

Set body_in_file_only to clean and adjust buffers for the client_max_body_size. The original question's config already had sendfile on, increase timeouts too. I use the settings below to fix this, appropriate across your local config, server, & http contexts.

client_body_in_file_only clean;
client_body_buffer_size 32K;

client_max_body_size 300M;

sendfile on;
send_timeout 300s;

I try with instruction:

npm install bootstrap
npm install jquery popper.js

then in src/index.js:

import 'bootstrap/dist/css/bootstrap.min.css';
import $ from 'jquery';
import Popper from 'popper.js';
import 'bootstrap/dist/js/bootstrap.bundle.min';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<Dropdown />, document.getElementById('root'));
registerServiceWorker();

That's how I've done it in angular2 (it is similar to that plunkered solution) In your HTML file:

<div id="print-section">
  // your html stuff that you want to print
</div>
<button (click)="print()">print</button>

and in your TS file :

print(): void {
    let printContents, popupWin;
    printContents = document.getElementById('print-section').innerHTML;
    popupWin = window.open('', '_blank', 'top=0,left=0,height=100%,width=auto');
    popupWin.document.open();
    popupWin.document.write(`
      <html>
        <head>
          <title>Print tab</title>
          <style>
          //........Customized style.......
          </style>
        </head>
    <body onload="window.print();window.close()">${printContents}</body>
      </html>`
    );
    popupWin.document.close();
}

UPDATE:

You can also shortcut the path and use merely ngx-print library for less inconsistent coding (mixing JS and TS) and more out-of-the-box controllable and secured printing cases.

In my case, I've added an Environment variable VCTargetPath with path

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\VC\VCTargets\"

('\' at the end is crucial, as the project solution files has a reference to "Microsoft cpp targets" file.

Also, starting from Visual Studio 2017 MSBUILD comes along within Visual Studio - so, the PATH variable needs to be updated with

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin

Updating VCTargetPath and MSBUILD's PATH variables and building fixed the error.

Just call moment as a function without any arguments:

Well in order to understand how static and dynamic binding actually works? or how they are identified by compiler and JVM?

Let's take below example where Mammal is a parent class which has a method speak() and Human class extends Mammal, overrides the speak() method and then again overloads it with speak(String language).

public class OverridingInternalExample {

    private static class Mammal {
        public void speak() { System.out.println("ohlllalalalalalaoaoaoa"); }
    }

    private static class Human extends Mammal {

        @Override
        public void speak() { System.out.println("Hello"); }

        // Valid overload of speak
        public void speak(String language) {
            if (language.equals("Hindi")) System.out.println("Namaste");
            else System.out.println("Hello");
        }

        @Override
        public String toString() { return "Human Class"; }

    }

    //  Code below contains the output and bytecode of the method calls
    public static void main(String[] args) {
        Mammal anyMammal = new Mammal();
        anyMammal.speak();  // Output - ohlllalalalalalaoaoaoa
        // 10: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Mammal humanMammal = new Human();
        humanMammal.speak(); // Output - Hello
        // 23: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Human human = new Human();
        human.speak(); // Output - Hello
        // 36: invokevirtual #7 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:()V

        human.speak("Hindi"); // Output - Namaste
        // 42: invokevirtual #9 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:(Ljava/lang/String;)V
    }
}

When we compile the above code and try to look at the bytecode using javap -verbose OverridingInternalExample, we can see that compiler generates a constant table where it assigns integer codes to every method call and byte code for the program which I have extracted and included in the program itself (see the comments below every method call)

By looking at above code we can see that the bytecodes of humanMammal.speak(), human.speak() and human.speak("Hindi") are totally different (invokevirtual #4, invokevirtual #7, invokevirtual #9) because the compiler is able to differentiate between them based on the argument list and class reference. Because all of this get resolved at compile time statically that is why Method Overloading is known as Static Polymorphism or Static Binding.

But bytecode for anyMammal.speak() and humanMammal.speak() is same (invokevirtual #4) because according to compiler both methods are called on Mammal reference.

So now the question comes if both method calls have same bytecode then how does JVM know which method to call?

Well, the answer is hidden in the bytecode itself and it is invokevirtual instruction set. JVM uses the invokevirtual instruction to invoke Java equivalent of the C++ virtual methods. In C++ if we want to override one method in another class we need to declare it as virtual, But in Java, all methods are virtual by default because we can override every method in the child class (except private, final and static methods).

In Java, every reference variable holds two hidden pointers

1. A pointer to a table which again holds methods of the object and a pointer to the Class object. e.g. [speak(), speak(String) Class object]
2. A pointer to the memory allocated on the heap for that object’s data e.g. values of instance variables.

So all object references indirectly hold a reference to a table which holds all the method references of that object. Java has borrowed this concept from C++ and this table is known as virtual table (vtable).

A vtable is an array like structure which holds virtual method names and their references on array indices. JVM creates only one vtable per class when it loads the class into memory.

So whenever JVM encounter with a invokevirtual instruction set, it checks the vtable of that class for the method reference and invokes the specific method which in our case is the method from a object not the reference.

Because all of this get resolved at runtime only and at runtime JVM gets to know which method to invoke, that is why Method Overriding is known as Dynamic Polymorphism or simply Polymorphism or Dynamic Binding.

You can read it more details on my article How Does JVM Handle Method Overloading and Overriding Internally.

Yet another way to use Rscript for *Unix systems is Process Substitution.

Rscript <(zcat a.r)
# [1] "hello"

Which obviously does the same as the accepted answer, but this allows you to manipulate and run your file without saving it the power of the command line, e.g.:

Rscript <(sed s/hello/bye/ a.r)
# [1] "bye"

Similar to Rscript -e "Rcode" it also allows to run without saving into a file. So it could be used in conjunction with scripts that generate R-code, e.g.:

Rscript <(echo "head(iris,2)")
# Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# 1          5.1         3.5          1.4         0.2  setosa
# 2          4.9         3.0          1.4         0.2  setosa

There's no need to use a library for such a trivial task:

var divs = document.getElementsByTagName("div");   // order: first, second, third
divs[2].parentNode.insertBefore(divs[2], divs[0]); // order: third, first, second
divs[2].parentNode.insertBefore(divs[2], divs[1]); // order: third, second, first

This takes account of the fact that getElementsByTagName returns a live NodeList that is automatically updated to reflect the order of the elements in the DOM as they are manipulated.

You could also use:

var divs = document.getElementsByTagName("div");   // order: first, second, third
divs[0].parentNode.appendChild(divs[0]);           // order: second, third, first
divs[1].parentNode.insertBefore(divs[0], divs[1]); // order: third, second, first

and there are various other possible permutations, if you feel like experimenting:

divs[0].parentNode.appendChild(divs[0].parentNode.replaceChild(divs[2], divs[0]));

for example :-)

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

You can use this regex:

^[A-Z][a-z]*(?:_[A-Z][a-z]*)*$

Sample code:

import re

strings = ["Alpha_beta_Gamma", "Alpha_Beta_Gamma"]
pattern = r'^[A-Z][a-z]*(?:_[A-Z][a-z]*)*$'

for s in strings:
    if re.match(pattern, s):
        print s + " conforms"
    else:
        print s + " doesn't conform"

As seen on codepad

goto menu File->Project Strucurt or key Ctrl + Alt + Shift + S

In the case where the problem is that System.loadLibrary cannot find the DLL in question, one common misconception (reinforced by Java's error message) is that the system property java.library.path is the answer. If you set the system property java.library.path to the directory where your DLL is located, then System.loadLibrary will indeed find your DLL. However, if your DLL in turn depends on other DLLs, as is often the case, then java.library.path cannot help, because the loading of the dependent DLLs is managed entirely by the operating system, which knows nothing of java.library.path. Thus, it is almost always better to bypass java.library.path and simply add your DLL's directory to LD_LIBRARY_PATH (Linux), DYLD_LIBRARY_PATH (MacOS), or Path (Windows) prior to starting the JVM.

(Note: I am using the term "DLL" in the generic sense of DLL or shared library.)

Use

.title{
  display: inline-block;
  height: 25px;
}

The only trick is browser support. Check if your list of supported browsers handles inline-block here.

Implement Login for Devices

Facebook Login for Devices is for devices that directly make HTTP calls over the internet. The following are the API calls and responses your device can make.

1. Enable Login for Devices

Change Settings > Advanced > OAuth Settings > Login from Devices to 'Yes'.

2. Generate a Code which is required for facebook device identification

When the person clicks Log in with Facebook, you device should make an HTTP POST to:

POST https://graph.facebook.com/oauth/device?
       type=device_code
       &amp;client_id=<YOUR_APP_ID>
       &amp;scope=<COMMA_SEPARATED_PERMISSION_NAMES> // e.g.public_profile,user_likes

The response comes in this form:

{
  "code": "92a2b2e351f2b0b3503b2de251132f47",
  "user_code": "A1NWZ9",
  "verification_uri": "https://www.facebook.com/device",
  "expires_in": 420,
  "interval": 5
}

This response means:

• Display the string “A1NWZ9” on your device
• Tell the person to go to “facebook.com/device” and enter this code
• The code expires in 420 seconds. You should cancel the login flow after that time if you do not receive an access token
• Your device should poll the Device Login API every 5 seconds to see if the authorization has been successful

3. Display the Code

Your device should display the user_code and tell people to visit the verification_uri such as facebook.com/device on their PC or smartphone. See the Design Guidelines.

4. Poll for Authorization

Your device should poll the Device Login API to see if the person successfully authorized your application. You should do this at the interval in the response to your call in Step 1, which is every 5 seconds. Your device should poll to:

POST https://graph.facebook.com/oauth/device?
       type=device_token
       &amp;client_id=<YOUR_APP_ID> 
       &amp;code=<LONG_CODE_FROM_STEP_1> //e.g."92a2b2e351f2b0b3503b2de251132f47"

You will get 200 HTTP code i.e User has successfully authorized the device. The device can now use the access_token value to make authenticated API calls.

5. Confirm Successful Login

Your device should display their name and if available, a profile picture until they click Continue. To get the person's name and profile picture, your device should make a standard Graph API call:

GET https://graph.facebook.com/v2.3/me?
      fields=name,picture&
      access_token=<USER_ACCESS_TOKEN>

Response:

{
  "name": "John Doe", 
  "picture": {
    "data": {
      "is_silhouette": false, 
      "url": "https://fbcdn.akamaihd.net/hmac...ile.jpg"
    }
  }, 
  "id": "2023462875238472"
}

6. Store Access Tokens

Your device should persist the access token to make other requests to the Graph API.

Device Login access tokens may be valid for up to 60 days but may be invalided in a number of scenarios. For example when a person changes their Facebook password their access token is invalidated.

If the token is invalid, your device should delete the token from its memory. The person using your device needs to perform the Device Login flow again from Step 1 to retrieve a new, valid token.

git status #then file which you need to push git add example.FileExtension

git commit "message is example"

git push -u origin(or whatever name you used) master(or name of some branch where you want to push it)

The startup project that references the project where Entity Framework is being used needs the following two assemblies in it's bin folder:

• EntityFramework.dll
• EntityFramework.SqlServer.dll

Adding a <section> to the <configSections> of the .config file on the startup project makes the first assembly available in that bin directory. You can copy this from the .config file of your Entity Framework project:

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>

To make the second .dll available in the bin folder, although not practical, a manual copy from the bin folder of the Entity Framework project can be made. A better alternative is to add to the Post-Build Events of the Entity Framework project the following lines, which will automate the process:

cd $(ProjectDir)
xcopy /y bin\Debug\EntityFramework.SqlServer.dll ..\{PATH_TO_THE_PROJECT_THAT_NEEDS_THE_DLL}\bin\Debug\

For demo code that conforms to POSIX standard as described in Setting Terminal Modes Properly and Serial Programming Guide for POSIX Operating Systems, the following is offered.
This code should execute correctly using Linux on x86 as well as ARM (or even CRIS) processors.
It's essentially derived from the other answer, but inaccurate and misleading comments have been corrected.

This demo program opens and initializes a serial terminal at 115200 baud for non-canonical mode that is as portable as possible.
The program transmits a hardcoded text string to the other terminal, and delays while the output is performed.
The program then enters an infinite loop to receive and display data from the serial terminal.
By default the received data is displayed as hexadecimal byte values.

To make the program treat the received data as ASCII codes, compile the program with the symbol DISPLAY_STRING, e.g.

 cc -DDISPLAY_STRING demo.c

If the received data is ASCII text (rather than binary data) and you want to read it as lines terminated by the newline character, then see this answer for a sample program.

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

1. mysqld.sock= actually resides under folder /run/mysqld/
2. ?> / ll /var/run
lrwxrwxrwx 1 root root 4 Nov 1 2018 /var/run -> /run/

hmmm... Does that mean a symbolic link won't work? That's weird...

you can use more elements "end" in print:

for iValue in arr:
   print(iValue, end = ", ");

By default xampp php log file path is in /xampp_installation_folder/php/logs/php_error_log, but I noticed that sometimes it would not be generated automatically. Maybe it could be a Windows account write permission problem? I am not sure, but I created the logs folder and php_error_log file manually and then php logs were logged in it finally.

Test with [char]9, such as:

$Tab = [char]9
Write-Output "$Tab hello"

Output:

     hello

tl;dr

Instant instant = myResultSet.getObject( … , Instant.class ) ;

…or, if your JDBC driver does not support the optional Instant, it is required to support OffsetDateTime:

OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;

Avoid both java.util.Date & java.sql.Timestamp. They have been replaced by the java.time classes. Specifically, the Instant class representing a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Different Values ? Unverified Problem

To address the main part of the Question: "Why different dates between java.util.Date and java.sql.Timestamp objects when one is derived from the other?"

There must be a problem with your code. You did not post your code, so we cannot pinpoint the problem.

First, that string value you show for value of java.util.Date did not come from its default toString method, so you obviously were doing additional operations.

Secondly, when I run similar code I do indeed get exact same date-time values.

First create a java.sql.Timestamp object.

// Timestamp
long millis1 =  new java.util.Date().getTime();
java.sql.Timestamp ts = new java.sql.Timestamp(millis1);

Now extract the count-of-milliseconds-since-epoch to instantiate a java.util.Date object.

// Date
long millis2 = ts.getTime();
java.util.Date date = new java.util.Date( millis2 );

Dump values to console.

System.out.println("millis1 = " + millis1 );
System.out.println("ts = " + ts );
System.out.println("millis2 = " + millis2 );
System.out.println("date = " + date );

When run.

millis1 = 1434666385642
ts = 2015-06-18 15:26:25.642
millis2 = 1434666385642
date = Thu Jun 18 15:26:25 PDT 2015

So the code shown in the Question is indeed a valid way to convert from java.sql.Timestamp to java.util.Date, though you will lose any nanoseconds data.

java.util.Date someDate = new Date( someJUTimestamp.getTime() ); 

Different Formats Of String Output

Note that the output of the toString methods is a different format, as documented. The java.sql.Timestamp follows SQL format, similar to ISO 8601 format but without the T in middle.

Ignore Inheritance

As discussed on comments on other Answers and the Question, you should ignore the fact that java.sql.Timestamp inherits from java.util.Date. The j.s.Timestamp doc clearly states that you should not view one as a sub-type of the other: (emphasis mine)

Due to the differences between the Timestamp class and the java.util.Date class mentioned above, it is recommended that code not view Timestamp values generically as an instance of java.util.Date. The inheritance relationship between Timestamp and java.util.Date really denotes implementation inheritance, and not type inheritance.

If you ignore the Java team’s advice and take such a view, one critical problem is that you will lose data: any microsecond or nanosecond part of a second that may be coming from the database is lost as a Date has only millisecond resolution.

Basically, all the old date-time classes from early Java are a big mess: java.util.Date, j.u.Calendar, java.text.SimpleDateFormat, java.sql.Timestamp/.Date/.Time. They were one of the first valiant efforts at a date-time framework in the industry, but ultimately they fail. Specifically here, java.sql.Timestamp is a java.util.Date with nanoseconds tacked on; this is a hack, not good design.

java.time

Avoid the old date-time classes bundled with early versions of Java.

Instead use the java.time package (Tutorial) built into Java 8 and later whenever possible.

Basics of java.time… An Instant is a moment on the timeline in UTC. Apply a time zone (ZoneId) to get a ZonedDateTime.

Example code using java.time as of Java 8. With a JDBC driver supporting JDBC 4.2 and later, you can directly exchange java.time classes with your database; no need for the legacy classes.

Instant instant = myResultSet.getObject( … , Instant.class) ;  // Instant is the raw underlying data, an instantaneous point on the time-line stored as a count of nanoseconds since epoch.

You may want to adjust into a time zone other than UTC.

ZoneId z = ZoneId.of( "America/Montreal" );  // Always make time zone explicit rather than relying implicitly on the JVM’s current default time zone being applied.
ZonedDateTime zdt = instant.atZone( z ) ;

Perform your business logic. Here we simply add a day.

ZonedDateTime zdtNextDay = zdt.plusDays( 1 ); // Add a day to get "day after".

At the last stage, if absolutely needed, convert to a java.util.Date for interoperability.

java.util.Date dateNextDay = Date.from( zdtNextDay.toInstant( ) );  // WARNING: Losing data (the nanoseconds resolution).

Dump to console.

System.out.println( "instant = " + instant );
System.out.println( "zdt = " + zdt );
System.out.println( "zdtNextDay = " + zdtNextDay );
System.out.println( "dateNextDay = " + dateNextDay );

When run.

instant = 2015-06-18T16:44:13.123456789Z
zdt = 2015-06-18T19:44:13.123456789-04:00[America/Montreal]
zdtNextDay = 2015-06-19T19:44:13.123456789-04:00[America/Montreal]
dateNextDay = Fri Jun 19 16:44:13 PDT 2015

Conversions

If you must use the legacy types to interface with old code not yet updated for java.time, you may convert. Use new methods added to the old java.util.Date and java.sql.* classes for conversion.

Instant instant = myJavaSqlTimestamp.toInstant() ;

…and…

java.sql.Timestamp ts = java.sql.Timestamp.from( instant ) ;

See the Tutorial chapter, Legacy Date-Time Code, for more info on conversions.

Fractional Second

Be aware of the resolution of the fractional second. Conversions from nanoseconds to milliseconds means potentially losing some data.

• Milliseconds
  • java.util.Date
  • Joda-Time (the framework that inspired java.time)
• Nanoseconds
  • java.sql.Timestamp
  • java.time

About java.time

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

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

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

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

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

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

If the relative path is a directory path, then try mine, should be the best:

absPath=$(pushd ../SOME_RELATIVE_PATH_TO_Directory > /dev/null && pwd && popd > /dev/null)

echo $absPath

This is what worked for me on windows:

Edit the pg_hba.conf file locates at C:\Program Files\PostgreSQL\9.3\data.

# IPv4 local connections: host all all 127.0.0.1/32 trust

Change the method from trust to md5 and restart the postgres service on windows.

After that, you can login using postgres user without password by using pgadmin. You can change password using File->Change password.

If postgres user does not have superuser privileges , then you cannot change the password. In this case , login with another user(pgsql)with superuser access and provide privileges to other users by right clicking on users and selecting properties->Role privileges.

This worked great I just add the -a option to ping to resolve the hostname. Thanks https://stackoverflow.com/users/4447323/wombat

Andrea is correct. we can do it using command line.

And we still can program it, by

ZkClient zkClient = new ZkClient("localhost:2181", 10000);
zkClient.deleteRecursive(ZkUtils.getTopicPath("test2"));

Actually I do not recommend you delete topic on Kafka 0.8.1.1. I can delete this topic by this method, but if you check log for zookeeper, deletion mess it up.

I Did that and it works for redirecting to other view I think If you add the #sectionLink after It will work

<a class="btn yellow" href="/users/Create/@Model.Id" target="_blank">
                                        Add As User
                                    </a>

Do this recursively:

public String replaceSpace(String s){
    if (s.length() < 2) {
        if(s.equals(" "))
            return "+";
        else
            return s;
    }
    if (s.charAt(0) == ' ')
        return "+" + replaceSpace(s.substring(1));
    else
        return s.substring(0, 1) + replaceSpace(s.substring(1));
}

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)

You can get the length of any 2nd dimension array as z[n].length where 0 <= n < z.length.

If you're treating your 2D array as a matrix, you can simply get z.length and z[0].length, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).
