I solved it by adding "edit permission" to the application of the site, mapped to the physical directory and then selected the windows user that could have access to this root folder. (private network).

Do NOT have trailing commas in your OBJECT (JSON is a string notation)

UPDATE: you need to use array.splice and not delete if you want to remove items from the array in the object. Alternatively filter the array for undefined after removing

var data = {
  "result": [{
    "FirstName": "Test1",
    "LastName": "User"
  }, {
    "FirstName": "user",
    "LastName": "user"
  }]
}
console.log(data.result);
console.log("------------ deleting -------------");
delete data.result[1];
console.log(data.result); // note the "undefined" in the array.


data = {
  "result": [{
    "FirstName": "Test1",
    "LastName": "User"
  }, {
    "FirstName": "user",
    "LastName": "user"
  }]
}

console.log(data.result);
console.log("------------ slicing -------------");
var deletedItem = data.result.splice(1,1);
console.log(data.result); // here no problem with undefined.

$ grep thestring thefile -5

-5 gets you 5 lines above and below the match 'thestring' is equivalent to -C 5 or -A 5 -B 5.

select 
  (select count(*) from foo) as foo
, (select count(*) from bar) as bar

There is no such thing in python like forward declaration. You just have to make sure that your function is declared before it is needed. Note that the body of a function isn't interpreted until the function is executed.

Consider the following example:

def a():
   b() # won't be resolved until a is invoked.

def b(): 
   print "hello"

a() # here b is already defined so this line won't fail.

You can think that a body of a function is just another script that will be interpreted once you call the function.

The graphviz conda package is no Python package. It simply puts the graphviz files into your virtual env's Library/ directory. Look e.g. for dot.exe in the Library/bin/ directory.

Update: There exists now a python-graphviz package at Anaconda.org which contains the Python interface for the graphviz tool. Simply install it with conda install python-graphviz.
(Thanks to wedran and g-kaklam for posting this solution and to endolith for notifying me).

Try

return Redirect::back()->withErrors(['msg', 'The Message']);

and inside your view call this

@if($errors->any())
<h4>{{$errors->first()}}</h4>
@endif

\t is a tab character. Use a raw string instead:

test_file=open(r'c:\Python27\test.txt','r')

or double the slashes:

test_file=open('c:\\Python27\\test.txt','r')

or use forward slashes instead:

test_file=open('c:/Python27/test.txt','r')

jQuery AJAX submit form, is nothing but submit a form using form ID when you click on a button

Please follow steps

Step 1 - Form tag must have an ID field

<form method="post" class="form-horizontal" action="test/user/add" id="submitForm">
.....
</form>

Button which you are going to click

<button>Save</button>

Step 2 - submit event is in jQuery which helps to submit a form. in below code we are preparing JSON request from HTML element name.

$("#submitForm").submit(function(e) {
    e.preventDefault();
    var frm = $("#submitForm");
    var data = {};
    $.each(this, function(i, v){
        var input = $(v);
        data[input.attr("name")] = input.val();
        delete data["undefined"];
    });
    $.ajax({
        contentType:"application/json; charset=utf-8",
        type:frm.attr("method"),
        url:frm.attr("action"),
        dataType:'json',
        data:JSON.stringify(data),
        success:function(data) {
            alert(data.message);
        }
    });
});

                                       }
                                   }];

Why write custom jQuery code for Marquee... just use a plugin for jQuery - marquee() and use it like in the example below:

First include :

<script type='text/javascript' src='//cdn.jsdelivr.net/jquery.marquee/1.3.1/jquery.marquee.min.js'></script>

and then:

//proporcional speed counter (for responsive/fluid use)
var widths = $('.marquee').width()
var duration = widths * 7;

$('.marquee').marquee({
    //speed in milliseconds of the marquee
    duration: duration, // for responsive/fluid use
    //duration: 8000, // for fixed container
    //gap in pixels between the tickers
    gap: $('.marquee').width(),
    //time in milliseconds before the marquee will start animating
    delayBeforeStart: 0,
    //'left' or 'right'
    direction: 'left',
    //true or false - should the marquee be duplicated to show an effect of continues flow
    duplicated: true
});

If you can make it simpler and better I dare you all people :). Don't make your life more difficult than it should be. More about this plugin and its functionalities at: http://aamirafridi.com/jquery/jquery-marquee-plugin

I've recently stumbled upon the following solution to this problem:

Source: Multiple versions of Chrome

...this is registry data problem: How to do it then (this is an example for 2.0.172.39 and 3.0.197.11, I'll try it with next versions as they will come, let's assume I've started with Chrome 2):

1. Install Chrome 2, you'll find it Application Data folder, since I'm from Czech Republic and my name is Bronislav Klucka the path looks like this:

   C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome
   

   and run Chrome

2. Open registry and save

   [HKEY_CURRENT_USER\Software\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   [HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   

   keys, put them into one chrome2.reg file and copy this file next to chrome.exe (ChromeDir\Application)

3. Rename Chrome folder to something else (e.g. Chrome2)

4. Install Chrome 3, it will install to Chrome folder again and run Chrome

5. Save the same keys (there are changes due to different version) and save it to the chrome3.reg file next to chrome.exe file of this new version again

6. Rename the folder again (e.g. Chrome3)

   the result would be that there is no Chrome dir (only Chrome2 and Chrome3)

7. Go to the Application folder of Chrome2, create chrome.bat file with this content:

   @echo off
   regedit /S chrome2.reg
   START chrome.exe -user-data-dir="C:\Docume~1\Bronis~1\LocalS~1\Dataap~1\Google\Chrome2\User Data"
   rem START chrome.exe -user-data-dir="C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome2\User Data"
   

   the first line is generic batch command, the second line will update registry with the content of chrome2.reg file, the third lines starts Chrome pointing to passed directory, the 4th line is commented and will not be run.

   Notice short name format passed as -user-data-dir parameter (the full path is at the 4th line), the problem is that Chrome using this parameter has a problem with diacritics (Czech characters)

8. Do 7. again for Chrome 3, update paths and reg file name in bat file for Chrome 3

Try running both bat files, seems to be working, both versions of Chrome are running simultaneously.

Updating: Running "About" dialog displays correct version, but an error while checking for new one. To correct that do (I'll explain form Chrome2 folder): 1. rename Chrome2 to Chrome 2. Go to Chrome/Application folder 3. run chrome2.reg file 4. run chrome.exe (works the same for Chrome3) now the version checking works. There has been no new version of Chrome since I've find this whole solution up. But I assume that update will be downloaded to this folder so all you need to do is to update reg file after update and rename Chrome folder back to Chrome2. I'll update this post after successful Chrome update.

The most versatile and safe method is putting the comment into a void quoted here-document, like this:

<<"COMMENT"
    This long comment text includes ${parameter:=expansion}
    `command substitution` and $((arithmetic++ + --expansion)).
COMMENT

Quoting the COMMENT delimiter above is necessary to prevent parameter expansion, command substitution and arithmetic expansion, which would happen otherwise, as Bash manual states and POSIX shell standard specifies.

In the case above, not quoting COMMENT would result in variable parameter being assigned text expansion, if it was empty or unset, executing command command substitution, incrementing variable arithmetic and decrementing variable expansion.

Comparing other solutions to this:

Using if false; then comment text fi requires the comment text to be syntactically correct Bash code whereas natural comments are often not, if only for possible unbalanced apostrophes. The same goes for : || { comment text } construct.

Putting comments into a single-quoted void command argument, as in :'comment text', has the drawback of inability to include apostrophes. Double-quoted arguments, as in :"comment text", are still subject to parameter expansion, command substitution and arithmetic expansion, the same as unquoted here-document contents and can lead to the side-effects described above.

Using scripts and editor facilities to automatically prefix each line in a block with '#' has some merit, but doesn't exactly answer the question.

1. I firstly added one off static table with ALL possibilities of my wildcard results (this company has a 4 character nvarchar code as their localities and they wildcard their locals) i.e. they may have 456? which would give them 456[1] to 456[Z] i.e 0-9 & a-z

2. I had to write a script to pull the current user (declare them) and pull the masks for the declared user.

3. Create some temporary tables just basic ones to rank the row numbers for this current user

4. loop through each result (YOUR Or this Or that etc...)

5. Insert into the test Table.

Here is the script I used:

Drop Table #UserMasks 
Drop Table #TESTUserMasks 

Create Table #TESTUserMasks (
    [User] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

Create Table #UserMasks (
    [RN] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

DECLARE @User INT
SET @User = 74054

Insert Into #UserMasks 
select ROW_NUMBER() OVER ( PARTITION BY ProntoUserID ORDER BY Id DESC) AS RN,
       REPLACE(mask,'?','') Mask
from dbo.Access_Masks 
where prontouserid = @User

DECLARE @TopFlag INT
SET @TopFlag = 1

WHILE (@TopFlag <=(select COUNT(*) from #UserMasks))
BEGIN
    Insert Into #TestUserMasks 
    select (@User),Code from dbo.MaskArrayLookupTable 
    where code like (select Mask + '%' from #UserMasks Where RN = @TopFlag)

    SET @TopFlag = @TopFlag + 1
END
GO

select * from #TESTUserMasks

if you have a regexp with groups:

str="A 54mpl3 string w1th 7 numbers scatter3r ar0und"
re=/(\d+)[m-t]/

you can use String's scan method to find matching groups:

str.scan re
#> [["54"], ["1"], ["3"]]

To find the matching pattern:

str.to_enum(:scan,re).map {$&}
#> ["54m", "1t", "3r"]

HttpContext.Response.AddHeader("content-disposition","attachment; filename=form.pdf");

if the filename is generating dynamically then how to define filename here, it is generating through guid here.

The question is relatively old, but I hope this post still might be relevant for others.

TL;DR: use AlarmManager to schedule a task, use IntentService, see the sample code here;

What this test-application(and instruction) is about:

Simple helloworld app, which sends you notification every 2 hours. Clicking on notification - opens secondary Activity in the app; deleting notification tracks.

When should you use it:

Once you need to run some task on a scheduled basis. My own case: once a day, I want to fetch new content from server, compose a notification based on the content I got and show it to user.

What to do:

1. First, let's create 2 activities: MainActivity, which starts notification-service and NotificationActivity, which will be started by clicking notification:

   activity_main.xml

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:padding="16dp">
       <Button
           android:id="@+id/sendNotifications"
           android:onClick="onSendNotificationsButtonClick"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Start Sending Notifications Every 2 Hours!" />
   </RelativeLayout>
   

   MainActivity.java

   public class MainActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
       }
   
       public void onSendNotificationsButtonClick(View view) {
           NotificationEventReceiver.setupAlarm(getApplicationContext());
       }   
   }
   

   and NotificationActivity is any random activity you can come up with. NB! Don't forget to add both activities into AndroidManifest.

2. Then let's create WakefulBroadcastReceiver broadcast receiver, I called NotificationEventReceiver in code above.

   Here, we'll set up AlarmManager to fire PendingIntent every 2 hours (or with any other frequency), and specify the handled actions for this intent in onReceive() method. In our case - wakefully start IntentService, which we'll specify in the later steps. This IntentService would generate notifications for us.

   Also, this receiver would contain some helper-methods like creating PendintIntents, which we'll use later

   NB1! As I'm using WakefulBroadcastReceiver, I need to add extra-permission into my manifest: <uses-permission android:name="android.permission.WAKE_LOCK" />

   NB2! I use it wakeful version of broadcast receiver, as I want to ensure, that the device does not go back to sleep during my IntentService's operation. In the hello-world it's not that important (we have no long-running operation in our service, but imagine, if you have to fetch some relatively huge files from server during this operation). Read more about Device Awake here.

   NotificationEventReceiver.java

   public class NotificationEventReceiver extends WakefulBroadcastReceiver {
   
       private static final String ACTION_START_NOTIFICATION_SERVICE = "ACTION_START_NOTIFICATION_SERVICE";
       private static final String ACTION_DELETE_NOTIFICATION = "ACTION_DELETE_NOTIFICATION";
       private static final int NOTIFICATIONS_INTERVAL_IN_HOURS = 2;
   
       public static void setupAlarm(Context context) {
           AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
           PendingIntent alarmIntent = getStartPendingIntent(context);
           alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                   getTriggerAt(new Date()),
                   NOTIFICATIONS_INTERVAL_IN_HOURS * AlarmManager.INTERVAL_HOUR,
                   alarmIntent);
       }
   
       @Override
       public void onReceive(Context context, Intent intent) {
           String action = intent.getAction();
           Intent serviceIntent = null;
           if (ACTION_START_NOTIFICATION_SERVICE.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive from alarm, starting notification service");
               serviceIntent = NotificationIntentService.createIntentStartNotificationService(context);
           } else if (ACTION_DELETE_NOTIFICATION.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive delete notification action, starting notification service to handle delete");
               serviceIntent = NotificationIntentService.createIntentDeleteNotification(context);
           }
   
           if (serviceIntent != null) {
               startWakefulService(context, serviceIntent);
           }
       }
   
       private static long getTriggerAt(Date now) {
           Calendar calendar = Calendar.getInstance();
           calendar.setTime(now);
           //calendar.add(Calendar.HOUR, NOTIFICATIONS_INTERVAL_IN_HOURS);
           return calendar.getTimeInMillis();
       }
   
       private static PendingIntent getStartPendingIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_START_NOTIFICATION_SERVICE);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   
       public static PendingIntent getDeleteIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_DELETE_NOTIFICATION);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   }
   

3. Now let's create an IntentService to actually create notifications.

   There, we specify onHandleIntent() which is responses on NotificationEventReceiver's intent we passed in startWakefulService method.

   If it's Delete action - we can log it to our analytics, for example. If it's Start notification intent - then by using NotificationCompat.Builder we're composing new notification and showing it by NotificationManager.notify. While composing notification, we are also setting pending intents for click and remove actions. Fairly Easy.

   NotificationIntentService.java

   public class NotificationIntentService extends IntentService {
   
       private static final int NOTIFICATION_ID = 1;
       private static final String ACTION_START = "ACTION_START";
       private static final String ACTION_DELETE = "ACTION_DELETE";
   
       public NotificationIntentService() {
           super(NotificationIntentService.class.getSimpleName());
       }
   
       public static Intent createIntentStartNotificationService(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_START);
           return intent;
       }
   
       public static Intent createIntentDeleteNotification(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_DELETE);
           return intent;
       }
   
       @Override
       protected void onHandleIntent(Intent intent) {
           Log.d(getClass().getSimpleName(), "onHandleIntent, started handling a notification event");
           try {
               String action = intent.getAction();
               if (ACTION_START.equals(action)) {
                   processStartNotification();
               }
               if (ACTION_DELETE.equals(action)) {
                   processDeleteNotification(intent);
               }
           } finally {
               WakefulBroadcastReceiver.completeWakefulIntent(intent);
           }
       }
   
       private void processDeleteNotification(Intent intent) {
           // Log something?
       }
   
       private void processStartNotification() {
           // Do something. For example, fetch fresh data from backend to create a rich notification?
   
           final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
           builder.setContentTitle("Scheduled Notification")
                   .setAutoCancel(true)
                   .setColor(getResources().getColor(R.color.colorAccent))
                   .setContentText("This notification has been triggered by Notification Service")
                   .setSmallIcon(R.drawable.notification_icon);
   
           PendingIntent pendingIntent = PendingIntent.getActivity(this,
                   NOTIFICATION_ID,
                   new Intent(this, NotificationActivity.class),
                   PendingIntent.FLAG_UPDATE_CURRENT);
           builder.setContentIntent(pendingIntent);
           builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
   
           final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
           manager.notify(NOTIFICATION_ID, builder.build());
       }
   }
   

4. Almost done. Now I also add broadcast receiver for BOOT_COMPLETED, TIMEZONE_CHANGED, and TIME_SET events to re-setup my AlarmManager, once device has been rebooted or timezone has changed (For example, user flown from USA to Europe and you don't want notification to pop up in the middle of the night, but was sticky to the local time :-) ).

   NotificationServiceStarterReceiver.java

   public final class NotificationServiceStarterReceiver extends BroadcastReceiver {
   
       @Override
       public void onReceive(Context context, Intent intent) {
           NotificationEventReceiver.setupAlarm(context);
       }
   }
   

5. We need to also register all our services, broadcast receivers in AndroidManifest:

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="klogi.com.notificationbyschedule">

           android:label="@string/app_name"
           android:supportsRtl="true"
           android:theme="@style/AppTheme">

This should works

$token = "YOUR_BEARER_AUTH_TOKEN";
//setup the request, you can also use CURLOPT_URL
$ch = curl_init('API_URL');

// Returns the data/output as a string instead of raw data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//Set your auth headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Authorization: Bearer ' . $token
   ));

// get stringified data/output. See CURLOPT_RETURNTRANSFER
$data = curl_exec($ch);

// get info about the request
$info = curl_getinfo($ch);
// close curl resource to free up system resources
curl_close($ch);

Files.write(Paths.get(filepath),texttobewrittentofile,StandardOpenOption.APPEND ,StandardOpenOption.CREATE);    

This creates a file, if it does not exist If files exists, it is uses the existing file and text is appended If you want everyline to be written to the next line add lineSepartor for newline into file.

String texttobewrittentofile = text + System.lineSeparator();

FYI (merged version of Tvanfosson)

it will return actual date => date when you are calling function

export const today = {
  iso: {
    start: () => new Date(new Date().setHours(0, 0, 0, 0)).toISOString(),
    now: () => new Date().toISOString(),
    end: () => new Date(new Date().setHours(23, 59, 59, 999)).toISOString()
  },
  local: {
  start: () => new Date(new Date(new Date().setHours(0, 0, 0, 0)).toString().split('GMT')[0] + ' UTC').toISOString(),
  now: () => new Date(new Date().toString().split('GMT')[0] + ' UTC').toISOString(),
  end: () => new Date(new Date(new Date().setHours(23, 59, 59, 999)).toString().split('GMT')[0] + ' UTC').toISOString()
  }
}

// how to use

today.local.now(); //"2018-09-07T01:48:48.000Z" BAKU +04:00
today.iso.now(); // "2018-09-06T21:49:00.304Z" * 

* it is applicable for Instant time type on Java8 which convert your local time automatically depending on your region.(if you are planning write global app)

Not sure if it will work with AngularJS v1.2.0-rc.2 with ui-router v0.2.0. I have tested this solution on AngularJS v1.3.14 with ui-router v0.2.13.

I just realize that is not necessary to pass the parameter in the URL as gwhn recommends.

Just add your parameters with a default value on your state definition. Your state can still have an Url value.

$stateProvider.state('state1', {
    url : '/url',
    templateUrl : "new.html",
    controller : 'TestController',
    params: {new_param: null}
});

and add the param to $state.go()

$state.go('state1',{new_param: "Going places!"});

It will work for both iphone and ipad

func showImagePicker() {
    var alertStyle = UIAlertController.Style.actionSheet
    if (UIDevice.current.userInterfaceIdiom == .pad) {
      alertStyle = UIAlertController.Style.alert
    }
    let alert = UIAlertController(title: "", message: "Upload Attachment", preferredStyle: alertStyle)
    alert.addAction(UIAlertAction(title: "Choose from gallery", style: .default , handler:{ (UIAlertAction) in
        self.pickPhoto(sourceType: .photoLibrary)
    }))
    alert.addAction(UIAlertAction(title: "Take Photo", style: .default, handler:{ (UIAlertAction) in
        self.pickPhoto(sourceType: .camera)
    }))
    alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler:{ (UIAlertAction) in
    }))
    present(alert, animated: true, completion: nil)
}

I think this problem can be solved with an easier way like this-

The class can be like-

using System;

namespace TSA
{
    class BirthDay
    {
        double ageDay;
        public BirthDay(int day, int month, int year)
        {
            DateTime birthDate = new DateTime(year, month, day);
            ageDay = (birthDate - DateTime.Now).TotalDays; //DateTime.UtcNow
        }

        internal int GetAgeYear()
        {
            return (int)Math.Truncate(ageDay / 365);
        }

        internal int GetAgeMonth()
        {
            return (int)Math.Truncate((ageDay % 365) / 30);
        }
    }
}

And calls can be like-

BirthDay b = new BirthDay(1,12,1990);
int year = b.GetAgeYear();
int month = b.GetAgeMonth();

I had exactly the same problem. Just one more working modification of the solution given by Denis (the type must be specified):

SELECT ARRAY(
SELECT column_name::text
FROM information_schema.columns
WHERE table_name='aean'
)

the main conception of this problem is about normal distribution, here provided a simple and recursive solution to this problem

presume we already have rand5() in our scope:

def rand7():
    # twoway = 0 or 1 in the same probability
    twoway = None
    while not twoway in (1, 2):
        twoway = rand5()
    twoway -= 1

    ans = rand5() + twoway * 5

    return ans if ans in range(1,8) else rand7()

Explanation

We can divide this program into 2 parts:

1. looping rand5() until we found 1 or 2, that means we have 1/2 probability to have 1 or 2 in the variable twoway
2. composite ans by rand5() + twoway * 5, this is exactly the result of rand10(), if this did not match our need (1~7), then we run rand7 again.

P.S. we cannot directly run a while loop in the second part due to each probability of twoway need to be individual.

But there is a trade-off, because of the while loop in the first section and the recursion in the return statement, this function doesn't guarantee the execution time, it is actually not effective.

Result

I've made a simple test for observing the distribution to my answer.

result = [ rand7() for x in xrange(777777) ]

ans = {
    1: 0,
    2: 0,
    3: 0,
    4: 0,
    5: 0,
    6: 0,
    7: 0,
}

for i in result:
    ans[i] += 1

print ans

It gave

{1: 111170, 2: 110693, 3: 110651, 4: 111260, 5: 111197, 6: 111502, 7: 111304}

Therefore we could know this answer is in a normal distribution.

Simplified Answer

If you don't care about the execution time of this function, here's a simplified answer based on the above answer I gave:

def rand7():
    ans = rand5() + (rand5()-1) * 5
    return ans if ans < 8 else rand7()

This augments the probability of value which is greater than 8 but probably will be the shortest answer to this problem.

This works i tried it my self i thought i post it here in case someone need it...

document.getElementById("newSkill").options[document.getElementById('newSkill').selectedIndex].text;

I'm using the CharacterEncodingFilter, configured in web.xml. Maybe that helps.

    <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>

window.location is an object, not a string so you need to use window.location.href to get the actual string url

if (window.location.href.indexOf("?added-to-cart=555") >= 0) {
    alert("found it");
}

useTimezone is an older workaround. MySQL team rewrote the setTimestamp/getTimestamp code fairly recently, but it will only be enabled if you set the connection parameter useLegacyDatetimeCode=false and you're using the latest version of mysql JDBC connector. So for example:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false

If you download the mysql-connector source code and look at setTimestamp, it's very easy to see what's happening:

If use legacy date time code = false, newSetTimestampInternal(...) is called. Then, if the Calendar passed to newSetTimestampInternal is NULL, your date object is formatted in the database's time zone:

this.tsdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss", Locale.US);
this.tsdf.setTimeZone(this.connection.getServerTimezoneTZ());
timestampString = this.tsdf.format(x);

It's very important that Calendar is null - so make sure you're using:

setTimestamp(int,Timestamp).

... NOT setTimestamp(int,Timestamp,Calendar).

It should be obvious now how this works. If you construct a date: January 5, 2011 3:00 AM in America/Los_Angeles (or whatever time zone you want) using java.util.Calendar and call setTimestamp(1, myDate), then it will take your date, use SimpleDateFormat to format it in the database time zone. So if your DB is in America/New_York, it will construct the String '2011-01-05 6:00:00' to be inserted (since NY is ahead of LA by 3 hours).

To retrieve the date, use getTimestamp(int) (without the Calendar). Once again it will use the database time zone to build a date.

Note: The webserver time zone is completely irrelevant now! If you don't set useLegacyDatetimecode to false, the webserver time zone is used for formatting - adding lots of confusion.

Note:

It's possible MySQL my complain that the server time zone is ambiguous. For example, if your database is set to use EST, there might be several possible EST time zones in Java, so you can clarify this for mysql-connector by telling it exactly what the database time zone is:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false&serverTimezone=America/New_York";

You only need to do this if it complains.

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

UPDATED 2020 TRY THIS WAY

python manage.py runserver yourIp:8000

ALLOWED_HOSTS = ["*"]

Whenever an array is created, its size is specified. So length can be considered as a construction attribute. For String, it essentially a char array. Length is a property of the char array. There is no need to put length as a field, because not everything needs this field. http://www.programcreek.com/2013/11/start-from-length-length-in-java/

I find it easier to access it by doing the following:

        for (int i = 0; i < Table.Rows.Count-1; i++) //Looping through rows
        {
            var myValue = Table.Rows[i]["MyFieldName"]; //Getting my field value

        }

You can use .is(':visible') to test if something is visible and .is(':hidden') to test for the opposite:

$('#offers').toggle(!$('#column-left form').is(':visible')); // or:
$('#offers').toggle($('#column-left form').is(':hidden'));

Reference:

• http://api.jquery.com/visible-selector/
• http://api.jquery.com/hidden-selector/

Scanf is pretty much always more trouble than it's worth. Here are two better ways to do what you're trying to do. This first one is a more-or-less direct translation of your code. It's longer, but you can look at it and see clearly what it does, unlike with scanf.

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    char buf[1024], *p, *q;
    while (fgets(buf, 1024, stdin))
    {
        p = buf;
        while (*p)
        {
            while (*p && isspace(*p)) p++;
            q = p;
            while (*q && !isspace(*q)) q++;
            *q = '\0';
            if (p != q)
                puts(p);
            p = q;
        }
    }
    return 0;
}

And here's another version. It's a little harder to see what this does by inspection, but it does not break if a line is longer than 1024 characters, so it's the code I would use in production. (Well, really what I would use in production is tr -s '[:space:]' '\n', but this is how you implement something like that.)

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    int ch, lastch = '\0';
    while ((ch = getchar()) != EOF)
    {
        if (!isspace(ch))
            putchar(ch);
        if (!isspace(lastch))
            putchar('\n');
        lastch = ch;
    }
    if (lastch != '\0' && !isspace(lastch))
        putchar('\n');
    return 0;
}

.btn is the best way, in modern website, it's not good while using anchor element without href so make the anchor tag to button is better.

For a structure definition that is to be used across more than one source file, you should definitely put it in a header file. Then include that header file in any source file that needs the structure.

The extern declaration is not used for structure definitions, but is instead used for variable declarations (that is, some data value with a structure type that you have defined). If you want to use the same variable across more than one source file, declare it as extern in a header file like:

extern struct a myAValue;

Then, in one source file, define the actual variable:

struct a myAValue;

If you forget to do this or accidentally define it in two source files, the linker will let you know about this.

This should work for you:

IF NOT EXIST "\path\to\your\folder" md \path\to\your\folder

However, there is another method, but it may not be 100% useful:

md \path\to\your\folder >NUL 2>NUL

This one creates the folder, but does not show the error output if folder exists. I highly recommend that you use the first one. The second one is if you have problems with the other.

import urllib2

try:
    fileHandle = urllib2.urlopen('http://www.python.org/fish.html')
    data = fileHandle.read()
    fileHandle.close()
except urllib2.URLError, e:
    print 'you got an error with the code', e

First, you can use sql command show global variables like 'innodb_buffer%'; to check the buffer size.

Solution is find your my.cnf file and add,

[mysqld]_x000D_
innodb_buffer_pool_size=1G # depends on your data and machine

DO NOT forget to add [mysqld], otherwise, it won't work.

In my case, ubuntu 16.04, my.cnf is located under the folder /etc/mysql/.

Using NetBeans 8.1, I got the dread

Error: Could not find or load main class 

from carelessly leaving an empty line in the Project Properties > Run > VM Options field. Until you click in the field, you may not see the caret flashing out of place. Remove the empty line to restore equanimity.

You could call getsockopt just like the following:

int error = 0;
socklen_t len = sizeof (error);
int retval = getsockopt (socket_fd, SOL_SOCKET, SO_ERROR, &error, &len);

To test if the socket is up:

if (retval != 0) {
    /* there was a problem getting the error code */
    fprintf(stderr, "error getting socket error code: %s\n", strerror(retval));
    return;
}

if (error != 0) {
    /* socket has a non zero error status */
    fprintf(stderr, "socket error: %s\n", strerror(error));
}

SQL*Plus uses &1, &2... &n to access the parameters.

Suppose you have the following script test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

Edit:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

so that your login/password won't be visible with another session's ps

I've converted the http://html5pattern.com/Dates Full Date Validation (YYYY-MM-DD) to DD/MM/YYYY Brazilian format:

I think I have a better answer.

new Timestamp(longEpochTime).toLocalDateTime();

It works for me in all the browsers:

document.onkeydown = function(){
  switch (event.keyCode){
        case 116 : //F5 button
            event.returnValue = false;
            event.keyCode = 0;
            return false;
        case 82 : //R button
            if (event.ctrlKey){ 
                event.returnValue = false;
                event.keyCode = 0;
                return false;
            }
    }
}

Get a list of all duplicate rows from table:

Select * from TABLE1 where PRIMARY_KEY_COLUMN NOT IN ( SELECT PRIMARY_KEY_COLUMN
FROM TABLE1 
GROUP BY DUP_COLUMN_NAME having (count(*) >= 1))

How? With annotations.

You simply annotate a POJO with a special annotation and library does the rest.

Warning!

I'm not sure that Hrisey, Lombok, and other code generation libraries are compatible with Android's new build system. They may or may not play nicely with hot swapping code (i.e. jRebel, Instant Run).

Pros:

• Code generation libraries save you from the boilerplate source code.
• Annotations make your class beautiful.

Cons:

• It works well for simple classes. Making a complex class parcelable may be tricky.
• Lombok and AspectJ don't play well together. ^[details]
• See my warnings.

Hrisey

Warning!

Hrisey has a known issue with Java 8 and therefore cannot be used for Android development nowadays. See #1 Cannot find symbol errors (JDK 8).

Hrisey is based on Lombok. Parcelable class using Hrisey:

@hrisey.Parcelable
public final class POJOClass implements android.os.Parcelable {
    /* Fields, accessors, default constructor */
}

Now you don't need to implement any methods of Parcelable interface. Hrisey will generate all required code during preprocessing phase.

Hrisey in Gradle dependencies:

provided "pl.mg6.hrisey:hrisey:${hrisey.version}"

See here for supported types. The ArrayList is among them.

Install a plugin - Hrisey xor Lombok* - for your IDE and start using its amazing features!

* Don't enable Hrisey and Lombok plugins together or you'll get an error during IDE launch.

Parceler

Parcelable class using Parceler:

@java.org.parceler.Parcel
public class POJOClass {
    /* Fields, accessors, default constructor */
}

To use the generated code, you may reference the generated class directly, or via the Parcels utility class using

public static <T> Parcelable wrap(T input);

To dereference the @Parcel, just call the following method of Parcels class

public static <T> T unwrap(Parcelable input);

Parceler in Gradle dependencies:

compile "org.parceler:parceler-api:${parceler.version}"
provided "org.parceler:parceler:${parceler.version}"

Look in README for supported attribute types.

AutoParcel

AutoParcel is an AutoValue extension that enables Parcelable values generation.

Just add implements Parcelable to your @AutoValue annotated models:

@AutoValue
abstract class POJOClass implements Parcelable {
    /* Note that the class is abstract */
    /* Abstract fields, abstract accessors */

    static POJOClass create(/*abstract fields*/) {
        return new AutoValue_POJOClass(/*abstract fields*/);
    }
}

AutoParcel in Gradle build file:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

repositories {
    /*...*/
    maven {url "https://clojars.org/repo/"}
}

dependencies {
    apt "frankiesardo:auto-parcel:${autoparcel.version}"
}

PaperParcel

PaperParcel is an annotation processor that automatically generates type-safe Parcelable boilerplate code for Kotlin and Java. PaperParcel supports Kotlin Data Classes, Google's AutoValue via an AutoValue Extension, or just regular Java bean objects.

Usage example from docs.
Annotate your data class with @PaperParcel, implement PaperParcelable, and add a JVM static instance of PaperParcelable.Creator e.g.:

@PaperParcel
public final class Example extends PaperParcelable {
    public static final PaperParcelable.Creator<Example> CREATOR = new PaperParcelable.Creator<>(Example.class);

    private final int test;

    public Example(int test) {
        this.test = test;
    }

    public int getTest() {
        return test;
    }
}

For Kotlin users, see Kotlin Usage; For AutoValue users, see AutoValue Usage.

ParcelableGenerator

ParcelableGenerator (README is written in Chinese and I don't understand it. Contributions to this answer from english-chinese speaking developers are welcome)

Usage example from README.

import com.baoyz.pg.Parcelable;

@Parcelable
public class User {

    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

}

The android-apt plugin assists in working with annotation processors in combination with Android Studio.

I would do something like:

select
 A.id, A.age, B.count 
from 
 students A, 
 (select age, count(*) as count from students group by age) B
where A.age=B.age;

Just make a selector for tables inside a MyClass.

.MyClass td {border: solid 1px red;}
.MyClass table td {border: none}

(To generically apply to all inner tables, you could also do table table td.)

Firts as mentioned by David, we need to set up public/private key.

Then using below command had worked for me, means it didn't prompt me for password as we are passing private key in the command using -i option

scp -i path/to/private_key path/to/local/file remoteUserId@remoteHost:/path/to/remote/folder

Here path/to/private_key is private key file which we generated while setting up public/private key.

You should read up on how to ensure that you've implemented equals and hashCode properly. This is a good starting point: What issues should be considered when overriding equals and hashCode in Java?

If you want to apply condition on the relational table you may use other solutions as well.. This solution is working from my end.

public static function getAllAvailableVideos() {
        $result = self::with(['videos' => function($q) {
                        $q->select('id', 'name');
                        $q->where('available', '=', 1);
                    }])                    
                ->get();
        return $result;
    }

For anyone that stumbles upon this page, none of the solutions here worked for me. I found this is the way to do it (in a batch file):

@for /f "skip=1" %%p in ('wmic cpu get loadpercentage /VALUE') do (
   for /F "tokens=2 delims==" %%J in ("%%p") do echo %%J
)

getElementById returns a reference to the element using its id. The element is the input in the first case and the paragraph in the second case.

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById

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

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

What are you trying to accomplish? If it's customization then you have a set of files to work with though that seems like a bad idea. Otherwise, I would suggest going with the full build of v4.1.x since that is the current release.

As @hitec said, you have to be sure that you have the right permissions, if you do, you can use this line to ensure the existence of the directory:

Directory.CreateDirectory(Path.GetDirectoryName(filePath))

Same as any other language, just pass index number of element that you want to retrieve.

#!/usr/bin/env python
x = [2,3,4,5,6,7]
print(x[5])

Method 1 :

rake db:migrate:up VERSION=20080906120000

Method 2:

In Rails Console 1. Copy paste the migration class in console (say add_name_to_user.rb) 2. Then in console, type the following

Sharding.run_on_all_shards{AddNameToUser.up}

It is done!!

There is nothing wrong with the idea of modifying an element inside a list while traversing it (don't modify the list itself, that's not recommended), but it can be better expressed like this:

for (int i = 0; i < letters.size(); i++) {
    letters.set(i, "D");
}

At the end the whole list will have the letter "D" as its content. It's not a good idea to use an enhanced for loop in this case, you're not using the iteration variable for anything, and besides you can't modify the list's contents using the iteration variable.

Notice that the above snippet is not modifying the list's structure - meaning: no elements are added or removed and the lists' size remains constant. Simply replacing one element by another doesn't count as a structural modification. Here's the link to the documentation quoted by @ZouZou in the comments, it states that:

A structural modification is any operation that adds or deletes one or more elements, or explicitly resizes the backing array; merely setting the value of an element is not a structural modification

How to break out in java??

Ans: Best way: System.exit(0);

Java language provides three jump statemnts that allow you to interrupt the normal flow of program.

These include break , continue ,return ,labelled break statement for e.g

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            outerLoop://Label
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break outerLoop;
                        }
                     System.out.println();                  
                    }
             System.out.println();
            }
    }   
}

Output: 1

Now Note below Program:

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break ;
                        }                   
                    }
             System.out.println();
            }
    }   
}

output:

1
11
111
1111

and so on upto

1111111111

Similarly you can use continue statement just replace break with continue in above example.

Things to Remember :

A case label cannot contain a runtime expressions involving variable or method calls

outerLoop:
Scanner s1=new Scanner(System.in);
int ans=s1.nextInt();
// Error s1 cannot be resolved

This question is the first link for a Spring Boot search, therefore, would be great to put here the solution recommended in the official documentation. Spring Boot has its own convenience bean RestTemplateBuilder:

@Bean
public RestTemplate restTemplate(
        RestTemplateBuilder restTemplateBuilder) {

    return restTemplateBuilder
            .setConnectTimeout(Duration.ofSeconds(500))
            .setReadTimeout(Duration.ofSeconds(500))
            .build();
}

Manual creation of RestTemplate instances is a potentially troublesome approach because other auto-configured beans are not being injected in manually created instances.

I ran into the same problem testing ASP.NET Web API

Developed Web.Host in Visual Studio 2013 Express Database created in SQL Server 2012 Express Executed test using built in IIS Express (working) Modified to use IIS Local (from properties page - web option) Ran test with Fiddler Received error - unable to open database for provider.... citing 'APPPOOL\DefaultAppPool'

Solution that worked.

In IIS

Click on application pool 'DefaultAppPool' Set Identify = 'ApplicationPoolIdentity' Set .NET framework = v4.0 (even though my app was 4.5)

In SQL Server Management Studio

Right click on Security folder (under the SQL Server engine so applies to all tables) Right click on User and add 'IIS APPPOOL\DefaultAppPool' In securables on the 'Grant' column check the options you want to give. Regarding the above if you are a DBA you probably know and want to control what those options are. If you are like me a developer just wanted to test your WEB API service which happens to also access SQL Server through EF 6 in MVC style then just check off everything. :) Yes I know but it worked.

Although many great answers were written to this question, none of them uses the Rspec tags approach.

I use tags to run one or more specs in different files -- only those related to my current development task.

For example, I add the tag "dev" with the value "current":

it "creates an user", dev: :current do
  user = create(:user)
  expect(user.persisted?).to be_truthy
end

then I run

bundle exec rspec . --tag dev:current

Different tags/values can be set in individual specs or groups.

As dfsq said i just had to use removeClass("hide") instead of toggle()

It seems that bames53's answer can be extended to defining integer and non-integer constant values in namespace and class declarations even if they get included in multiple source files. It is not necessary to put the declarations in a header file but the definitions in a source file. The following example works for Microsoft Visual Studio 2015, for z/OS V2.2 XL C/C++ on OS/390, and for g++ (GCC) 8.1.1 20180502 on GNU/Linux 4.16.14 (Fedora 28). Note that the constants are declared/defined in only a single header file that gets included in multiple source files.

In foo.cc:

#include <cstdio>               // for puts

#include "messages.hh"
#include "bar.hh"
#include "zoo.hh"

int main(int argc, const char* argv[])
{
  puts("Hello!");
  bar();
  zoo();
  puts(Message::third);
  return 0;
}

In messages.hh:

#ifndef MESSAGES_HH
#define MESSAGES_HH

namespace Message {
  char const * const first = "Yes, this is the first message!";
  char const * const second = "This is the second message.";
  char const * const third = "Message #3.";
};

#endif

In bar.cc:

#include "messages.hh"
#include <cstdio>

void bar(void)
{
  puts("Wow!");
  printf("bar: %s\n", Message::first);
}

In zoo.cc:

#include <cstdio>
#include "messages.hh"

void zoo(void)
{
  printf("zoo: %s\n", Message::second);
}

In bar.hh:

#ifndef BAR_HH
#define BAR_HH

#include "messages.hh"

void bar(void);

#endif

In zoo.hh:

#ifndef ZOO_HH
#define ZOO_HH

#include "messages.hh"

void zoo(void);

#endif

This yields the following output:

Hello!
Wow!
bar: Yes, this is the first message!
zoo: This is the second message.
Message #3.

The data type char const * const means a constant pointer to an array of constant characters. The first const is needed because (according to g++) "ISO C++ forbids converting a string constant to 'char*'". The second const is needed to avoid link errors due to multiple definitions of the (then insufficiently constant) constants. Your compiler might not complain if you omit one or both of the consts, but then the source code is less portable.

Use this command 

\d table name

like 

\d queuerecords

             Table "public.queuerecords"
  Column   |            Type             | Modifiers
-----------+-----------------------------+-----------
 id        | uuid                        | not null
 endtime   | timestamp without time zone |
 payload   | text                        |
 queueid   | text                        |
 starttime | timestamp without time zone |
 status    | text                        |

If you really need it inline, for example because you are loading some user-defined colors dynamically, you can always add a <style> element right before your content.

<style>#project-slide-1:before { color: #ff0000; }</style>
<div id="project-slide-1" class="project-slide"> ... </div>

Example use case with PHP and some (wordpress inspired) dummy functions:

<style>#project-slide-<?php the_ID() ?>:before { color: <?php the_field('color') ?>; }</style>
<div id="project-slide-<?php the_ID() ?>" class="project-slide"> ... </div>

Since HTML 5.2 it is valid to place style elements inside the body, although it is still recommend to place style elements in the head.

• Reports memory used by the current process as a whole, not individual functions within

But nice because of its simplicity:

import resource
def using(point=""):
    usage=resource.getrusage(resource.RUSAGE_SELF)
    return '''%s: usertime=%s systime=%s mem=%s mb
           '''%(point,usage[0],usage[1],
                usage[2]/1024.0 )

Just insert using("Label") where you want to see what's going on. For example

print(using("before"))
wrk = ["wasting mem"] * 1000000
print(using("after"))

>>> before: usertime=2.117053 systime=1.703466 mem=53.97265625 mb
>>> after: usertime=2.12023 systime=1.70708 mem=60.8828125 mb

buttonB.setIcon(new ImageIcon(this.getClass().getResource("imagename")));

To do this in Windows CLI environment, the best way I can find is to use the mode command and parse the output.

function getTerminalSizeOnWindows() {
  $output = array();
  $size = array('width'=>0,'height'=>0);
  exec('mode',$output);
  foreach($output as $line) {
    $matches = array();
    $w = preg_match('/^\s*columns\:?\s*(\d+)\s*$/i',$line,$matches);
    if($w) {
      $size['width'] = intval($matches[1]);
    } else {
      $h = preg_match('/^\s*lines\:?\s*(\d+)\s*$/i',$line,$matches);
      if($h) {
        $size['height'] = intval($matches[1]);
      }
    }
    if($size['width'] AND $size['height']) {
      break;
    }
  }
  return $size;
}

I hope it's useful!

NOTE: The height returned is the number of lines in the buffer, it is not the number of lines that are visible within the window. Any better options out there?

Your server process has received a SIGPIPE writing to a socket. This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close function).

In a C program you would normally try setting to ignore SIGPIPE signal or setting a dummy signal handler for it. In this case a simple error will be returned when writing to a closed socket. In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.

I've slightly edited SwiftDeveloper's answer, because it wasn't working for me. I added Alamofire validation as well.

let body: NSMutableDictionary? = [
    "name": "\(nameLabel.text!)",
    "phone": "\(phoneLabel.text!))"]

let url = NSURL(string: "http://server.com" as String)
var request = URLRequest(url: url! as URL)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
let data = try! JSONSerialization.data(withJSONObject: body!, options: JSONSerialization.WritingOptions.prettyPrinted)

let json = NSString(data: data, encoding: String.Encoding.utf8.rawValue)
if let json = json {
    print(json)
}
request.httpBody = json!.data(using: String.Encoding.utf8.rawValue)
let alamoRequest = Alamofire.request(request as URLRequestConvertible)
alamoRequest.validate(statusCode: 200..<300)
alamoRequest.responseString { response in

    switch response.result {
        case .success:
            ...
        case .failure(let error):
            ...
    }

Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.

TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.

Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):

When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the SynchronizationContext.Current which gets the synchronization context for the current thread. SynchronizationContext.Current is populated depending on the environment you are in. The GetAwaiter method of Task looks up for SynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.

When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because SynchronizationContext.Current is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!

Also, here are two great articles for you which are exactly for your question:

• The Perfect Recipe to Shoot Yourself in The Foot - Ending up with a Deadlock Using the C# 5.0 Asynchronous Language Features
• Asynchronous .NET Client Libraries for Your HTTP API and Awareness of async/await's Bad Effects

Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).

Hope this helps.

For anyone that's searching why their chrome debugger is automatically jumping to sources tab on every page load, event though all of the breakpoints/pauses/etc have been disabled.

For me it was the "breakOnLoad": true line in VS Code launch.json config.

Just remember, if the field you want to make nullable is part of a primary key, you can't. Primary Keys cannot have null fields.

This accomplishes the same thing but is much simpler:

$(document).ready(function() {  
   $("#board").delay(1000).append(".");
});

You can chain a delay before almost any jQuery method.

In some sort of main or first loading CSS file, just do:

@import url('https://fonts.googleapis.com/css?family=Source+Sans+Pro:regular,bold,italic&subset=latin,latin-ext');

You don't need to wrap in any sort of @font-face, etc. the response you get back from Google's API is ready to go and lets you use font families like normal.

Then in your main React app JavaScript, at the top put something like:

import './assets/css/fonts.css';

What I did actually was made an app.css that imported a fonts.css with a few font imports. Simply for organization (now I know where all my fonts are). The important thing to remember is that you import the fonts first.

Keep in mind that any component you import to your React app should be imported after the style import. Especially if those components also import their own styles. This way you can be sure of the ordering of styles. This is why it's best to import fonts at the top of your main file (don't forget to check your final bundled CSS file to double check if you're having trouble).

There's a few options you can pass the Google Font API to be more efficient when loading fonts, etc. See official documentation: Get Started with the Google Fonts API

Edit, note: If you are dealing with an "offline" application, then you may indeed need to download the fonts and load through Webpack.

Besides the answer given above, I just want to add that this error can also occur while importing data with incorrect lines terminated character.

For example I save the dump file in csv format in windows. then while importing

LOAD DATA INFILE '/path_to_csv_folder/db.csv' INTO TABLE table1
 FIELDS TERMINATED BY ',' 
 ENCLOSED BY '"'
 ESCAPED BY '"'
 LINES TERMINATED BY '\n'
IGNORE 1 LINES;

Windows saved end of line as \r\n (i.e. CF LF) where as I was using \n. I was getting crazy why phpMyAdmin was able to import the file while I couldn't. Only when I open the file in notepadd++ and saw the end of file then I realized that mysql was unable to find any lines terminated symbol (and I guess it consider all the lines as input to the field; making it complain.)

Anyway after making from \n to \r\n; it work like a charm.

LOAD DATA INFILE '/path_to_csv_folder/db.csv' INTO TABLE table1
 FIELDS TERMINATED BY ',' 
 ENCLOSED BY '"'
 ESCAPED BY '"'
 LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;

As stated in the answer by Henrik, titles are left-aligned by default starting with ggplot 2.2.0. Titles can be centered by adding this to the plot:

theme(plot.title = element_text(hjust = 0.5))

However, if you create many plots, it may be tedious to add this line everywhere. One could then also change the default behaviour of ggplot with

theme_update(plot.title = element_text(hjust = 0.5))

Once you have run this line, all plots created afterwards will use the theme setting plot.title = element_text(hjust = 0.5) as their default:

theme_update(plot.title = element_text(hjust = 0.5))
ggplot() + ggtitle("Default is now set to centered")

To get back to the original ggplot2 default settings you can either restart the R session or choose the default theme with

theme_set(theme_gray())

How about calling the .NET Framework methods?

You can do ANYTHING with them... :

[System.IO.File]::Copy($src, $dest, $true);

The $true argument makes it overwrite.

another way to solve this: preg_match('/^\d+\.\d+$/',$number); :)

No, you will have to use OR to combine your LIKE statements:

SELECT 
   * 
FROM 
   table
WHERE 
   column LIKE 'Text%' OR 
   column LIKE 'Link%' OR 
   column LIKE 'Hello%' OR
   column LIKE '%World%'

Have you looked at Full-Text Search?

Is the action method on your form pointing to /controller/edit/1?

Try using one of these:

// the null in the last position is the html attributes, which you usually won't use
// on a form.  These invocations are kinda ugly
Html.BeginForm("Edit", "User", new { Id = Model.Id }, FormMethod.Post, null)

Html.BeginForm(new { action="Edit", controller="User", id = Model.Id })

Or inside your form add a hidden "Id" field

@Html.HiddenFor(m => m.Id)

Use the correct call: strptime is a classmethod of the datetime.datetime class, it's not a function in the datetime module.

self.date = datetime.datetime.strptime(self.d, "%Y-%m-%d")

As mentioned by Jon Clements in the comments, some people do from datetime import datetime, which would bind the datetime name to the datetime class, and make your initial code work.

To identify which case you're facing (in the future), look at your import statements

• import datetime: that's the module (that's what you have right now).
• from datetime import datetime: that's the class.

And you can use HTML5's autofocus attribute (works in all current browsers except IE9 and below). Only call your script if it's IE9 or earlier, or an older version of other browsers.

<input type="text" name="fname" autofocus>

Use DATE() function:

select * from follow_queue group by DATE(follow_date)

Assuming you use VS Express and C#. The icon is set in the project properties page. To open it right click on the project name in the solution explorer. in the page that opens, there is an Application tab, in this tab you can set the icon.

If you (or other searchers of this question) were actually interested in creating a contiguous array to fill with integers, consider bytearray and memoryivew:

# cast() is available starting Python 3.3
size = 10**6 
ints = memoryview(bytearray(size)).cast('i') 

ints.contiguous, ints.itemsize, ints.shape
# (True, 4, (250000,))

ints[0]
# 0

ints[0] = 16
ints[0]
# 16

If you are in Chrome you can check the Post Data

Here is How to check the Post data

1. Go to Network Tab
2. Look for the Link to which you are sending Post Data
3. Click on it
4. In the Headers, you can check Request Payload to check the post data

The proper syntax would be - ALTER TABLE Table_Name ADD UNIQUE (column_name)

Example

ALTER TABLE  0_value_addition_setup ADD UNIQUE (`value_code`)

Answers that suggest that the header provided in the question are supported out of the box by WCF are incorrect. The header in the question contains a Nonce and a Created timestamp in the UsernameToken, which is an official part of the WS-Security specification that WCF does not support. WCF only supports username and password out of the box.

If all you need to do is add a username and password, then Sergey's answer is the least-effort approach. If you need to add any other fields, you will need to supply custom classes to support them.

A somewhat more elegant approach that I found was to override the ClientCredentials, ClientCredentialsSecurityTokenManager and WSSecurityTokenizer classes to support the additional properties. I've provided a link to the blog post where the approach is discussed in detail, but here is the sample code for the overrides:

public class CustomCredentials : ClientCredentials
{
    public CustomCredentials()
    { }

    protected CustomCredentials(CustomCredentials cc)
        : base(cc)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager()
    {
        return new CustomSecurityTokenManager(this);
    }

    protected override ClientCredentials CloneCore()
    {
        return new CustomCredentials(this);
    }
}

public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager
{
    public CustomSecurityTokenManager(CustomCredentials cred)
        : base(cred)
    { }

    public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version)
    {
        return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11);
    }
}

public class CustomTokenSerializer : WSSecurityTokenSerializer
{
    public CustomTokenSerializer(SecurityVersion sv)
        : base(sv)
    { }

    protected override void WriteTokenCore(System.Xml.XmlWriter writer,
                                            System.IdentityModel.Tokens.SecurityToken token)
    {
        UserNameSecurityToken userToken = token as UserNameSecurityToken;

        string tokennamespace = "o";

        DateTime created = DateTime.Now;
        string createdStr = created.ToString("yyyy-MM-ddTHH:mm:ss.fffZ");

        // unique Nonce value - encode with SHA-1 for 'randomness'
        // in theory the nonce could just be the GUID by itself
        string phrase = Guid.NewGuid().ToString();
        var nonce = GetSHA1String(phrase);

        // in this case password is plain text
        // for digest mode password needs to be encoded as:
        // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password))
        // and profile needs to change to
        //string password = GetSHA1String(nonce + createdStr + userToken.Password);

        string password = userToken.Password;

        writer.WriteRaw(string.Format(
        "<{0}:UsernameToken u:Id=\"" + token.Id +
        "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" +
        "<{0}:Username>" + userToken.UserName + "</{0}:Username>" +
        "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" +
        password + "</{0}:Password>" +
        "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" +
        nonce + "</{0}:Nonce>" +
        "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace));
    }

    protected string GetSHA1String(string phrase)
    {
        SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider();
        byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase));
        return Convert.ToBase64String(hashedDataBytes);
    }

}

Before creating the client, you create the custom binding and manually add the security, encoding and transport elements to it. Then, replace the default ClientCredentials with your custom implementation and set the username and password as you would normally:

var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement();
    security.IncludeTimestamp = false;
    security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256;
    security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10;

var encoding = new TextMessageEncodingBindingElement();
encoding.MessageVersion = MessageVersion.Soap11;

var transport = new HttpsTransportBindingElement();
transport.MaxReceivedMessageSize = 20000000; // 20 megs

binding.Elements.Add(security);
binding.Elements.Add(encoding);
binding.Elements.Add(transport);

RealTimeOnlineClient client = new RealTimeOnlineClient(binding,
    new EndpointAddress(url));

    client.ChannelFactory.Endpoint.EndpointBehaviors.Remove(client.ClientCredentials);
client.ChannelFactory.Endpoint.EndpointBehaviors.Add(new CustomCredentials());

client.ClientCredentials.UserName.UserName = username;
client.ClientCredentials.UserName.Password = password;

The simplest is to use replace:

"foo bar\t".replace(" ", "").replace("\t", "")

Alternatively, use a regular expression:

import re
re.sub(r"\s", "", "foo bar\t")

It's all about display: block :)

Updated:

Ok so you have the table, tr and td tags:

<table>
  <tr>
    <td>
      <!-- your image goes here -->
    </td>
  </tr>
</table>

Lets say your table or td (whatever define your width) has property width: 360px;. Now, when you try to replace the html comment with the actual image and set that image property for example width: 100%; which should fully fill out the td cell you will face the problem.

The problem is that your table cell (td) isn't properly filled with the image. You'll notice the space at the bottom of the cell which your image doesn't cover (it's like 5px of padding).

How to solve this in a simpliest way?

You are working with the tables, right? You just need to add the display property to your image so that it has the following:

img {
  width: 100%;
  display: block;
}

I only have the need to push files during a build, so I just added a Post-build Event Command Line entry like this:

Copy /Y "$(SolutionDir)Third Party\SomeLibrary\*" "$(TargetDir)"

You can set this by right-clicking your Project in the Solution Explorer, then Properties > Build Events

From the Javascript implementation of trim() > that removes and leading or ending spaces from strings. Here is an altered implementation of the answer for this question.

var str = "0000one two three0000"; //TEST  
str = str.replace(/^\s+|\s+$/g,'0'); //ANSWER

Original implementation for this on JS

string.trim():
if (!String.prototype.trim) {
 String.prototype.trim = function() {
  return this.replace(/^\s+|\s+$/g,'');
 }
}

I recast Brajesh Kumar's answer above into Clojure as follows:

(defn open-browser 
  "Open a new browser (window or tab) viewing the document at this `uri`."
  [uri]
  (if (java.awt.Desktop/isDesktopSupported)
    (let [desktop (java.awt.Desktop/getDesktop)]
      (.browse desktop (java.net.URI. uri)))
    (let [rt (java.lang.Runtime/getRuntime)]
      (.exec rt (str "xdg-open " uri)))))

in case it's useful to anyone.

ImageMagick, the free and open source image manipulation toolkit, can easily do this:

Note: Since ImageMagick 7, the CLI has changed slightly, you need to add magick in front of any commands.

magick convert icon-16.png icon-32.png icon-64.png icon-128.png icon.ico

See also http://www.imagemagick.org/Usage/thumbnails/#favicon, that has the example:

magick convert image.png -bordercolor white -border 0 \
          \( -clone 0 -resize 16x16 \) \
          \( -clone 0 -resize 32x32 \) \
          \( -clone 0 -resize 48x48 \) \
          \( -clone 0 -resize 64x64 \) \
          -delete 0 -alpha off -colors 256 favicon.ico

There is also now the shorter:

magick convert image.png -define icon:auto-resize="256,128,96,64,48,32,16" favicon.ico

we are in 2017 now you can also use ES2016

var a = 'abc123.8<blah>';
console.log([...a].filter( e => isFinite(e)).join(''));

or

console.log([...'abc123.8<blah>'].filter( e => isFinite(e)).join(''));  

The result is

1238

You can make a hyperlink in Telegram by writing an URL and send the message. Using Telegram Bot APIs you can send a clickable URL in two ways:

Markdown:

[This is an example](https://example.com)

HTML:

<a href="https://example.com">This is an example</a>

In both cases you will have:

This is an example

EDIT: In new version of Telegram clients you can do that, see above answers.

If it's a server socket, you should call listen() on your socket, and then getsockname() to find the port number on which it is listening:

struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
    perror("getsockname");
else
    printf("port number %d\n", ntohs(sin.sin_port));

As for the IP address, if you use INADDR_ANY then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname() on the socket for a specific connection (which you get from accept()) in order to find out which local IP address is being used on that connection.

If you declare a DateTime, then the default value is DateTime.MinValue, and hence you have to check it like this:

DateTime dat = new DateTime();

 if (dat==DateTime.MinValue)
 {
     //unassigned
 }

If the DateTime is nullable, well that's a different story:

 DateTime? dat = null;

 if (!dat.HasValue)
 {
     //unassigned
 }

Git and DVCS in general is great for developers doing a lot of coding independently of each other because everyone has their own branch. If you need a change from someone else, though, she has to commit to her local repo and then she must push that changeset to you or you must pull it from her.

My own reasoning also makes me think DVCS makes things harder for QA and release management if you do things like centralized releases. Someone has to be responsible for doing that push/pull from everyone else's repository, resolving any conflicts that would have been resolved at initial commit time before, then doing the build, and then having all the other developers re-sync their repos.

All of this can be addressed with human processes, of course; DVCS just broke something that was fixed by centralized version control in order to provide some new conveniences.

Angular 8 HttpClient Service example with Error Handling and Custom Header

    import { HttpClient, HttpHeaders, HttpErrorResponse } from '@angular/common/http';
    import { Student } from '../model/student';
    import { Observable, throwError } from 'rxjs';
    import { retry, catchError } from 'rxjs/operators';

    @Injectable({
      providedIn: 'root'
    })
    export class ApiService {

      // API path
      base_path = 'http://localhost:3000/students';

      constructor(private http: HttpClient) { }

      }

      // Handle API errors
      handleError(error: HttpErrorResponse) {
        if (error.error instanceof ErrorEvent) {
          // A client-side or network error occurred. Handle it accordingly.
          console.error('An error occurred:', error.error.message);
        } else {
          // The backend returned an unsuccessful response code.
          // The response body may contain clues as to what went wrong,
          console.error(
            `Backend returned code ${error.status}, ` +
            `body was: ${error.error}`);
        }
        // return an observable with a user-facing error message

echo "$string" | tr xyz _

would replace each occurrence of x, y, or z with _, giving A__BC___DEF__LMN in your example.

echo "$string" | sed -r 's/[xyz]+/_/g'

would replace repeating occurrences of x, y, or z with a single _, giving A_BC_DEF_LMN in your example.

Azure Data Studio - free and from Microsoft - offers automatic formatting (ctrl + shift + p while editing -> format document). More information about Azure Data Studio here.

While this is not SSMS, it's great for writing queries, free and an official product from Microsoft. It's even cross-platform. Short story: Just switch to Azure Data Studio to write your queries!

Update: Actually Azure Data Studio is in some way the recommended tool for writing queries (source)

Use Azure Data Studio if you: [..] Are mostly editing or executing queries.

This is another example using defined column/table names.

I was getting selectNode() param 1 is not of type node error.

changed the code to this and its working. (for chrome)

function copy_data(containerid) {_x000D_
  var range = document.createRange();_x000D_
  range.selectNode(containerid); //changed here_x000D_
  window.getSelection().removeAllRanges(); _x000D_
  window.getSelection().addRange(range); _x000D_

Pure CSS only for nav tabs, very simple for small screens:

@media (max-width: 767px) {
     .nav-tabs {
         min-width: 100%;
         display: inline-grid;
     }
}

In SwiftUI, The simplest implementation would be,

struct MyTextField: View {
  var myPlaceHolder: String
  @Binding var text: String

  var underColor: Color
  var height: CGFloat

  var body: some View {
    VStack {
        TextField(self.myPlaceHolder, text: $text)
        .padding(.horizontal, 24)
        .font(.title)

        Rectangle().frame(height: self.height)
            .padding(.horizontal, 24).foregroundColor(self.underColor)
    }
  }
}

Usage:

MyTextField(myPlaceHolder: "PlaceHolder", text: self.$text, underColor: .red, height: 3)

convert a 1-dimensional array into a 2-dimensional array by adding new axis.

a=np.array([10,20,30,40,50,60])

b=a[:,np.newaxis]--it will convert it to two dimension.

Yes you only need $() when you're using jQuery. If you want jQuery's help to do DOM things just keep this in mind.

$(this)[0] === this

Basically every time you get a set of elements back jQuery turns it into a jQuery object. If you know you only have one result, it's going to be in the first element.

$("#myDiv")[0] === document.getElementById("myDiv");

And so on...

Since this is a matter of finding files, let's use find!

Using GNU find you can use the -regex option to find those files in the tree of directories whose extension is either .h or .cpp:

find -type f -regex ".*\.\(h\|cpp\)"
#            ^^^^^^^^^^^^^^^^^^^^^^^

Then, it is just a matter of executing grep on each of its results:

find -type f -regex ".*\.\(h\|cpp\)" -exec grep "your pattern" {} +

If you don't have this distribution of find you have to use an approach like Amir Afghani's, using -o to concatenate options (the name is either ending with .h or with .cpp):

find -type f \( -name '*.h' -o -name '*.cpp' \) -exec grep "your pattern" {} +
#            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

And if you really want to use grep, follow the syntax indicated to --include:

grep "your pattern" -r --include=*.{cpp,h}
#                      ^^^^^^^^^^^^^^^^^^^

I had the same problem on windows "error: failed to execute prompt script (exit code 1) fatal: could not read Username for 'https://github.com': No error" trying to login to github through the login dialog.

I use one main Javascript function that I had found at Mozilla Developer Network site https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications, along with another function with AJAX and changed according to my needs. It receives a document element id regarding the place in my html code where I want to write the file size.

<Javascript>

function updateSize(elementId) {
    var nBytes = 0,
    oFiles = document.getElementById(elementId).files,
    nFiles = oFiles.length;

    for (var nFileId = 0; nFileId < nFiles; nFileId++) {
        nBytes += oFiles[nFileId].size;
    }
    var sOutput = nBytes + " bytes";
    // optional code for multiples approximation
    for (var aMultiples = ["K", "M", "G", "T", "P", "E", "Z", "Y"], nMultiple = 0, nApprox = nBytes / 1024; nApprox > 1; nApprox /= 1024, nMultiple++) {
        sOutput = " (" + nApprox.toFixed(3) + aMultiples[nMultiple] + ")";
    }

    return sOutput;
}
</Javascript>

<HTML>
<input type="file" id="inputFileUpload" onchange="uploadFuncWithAJAX(this.value);" size="25">
</HTML>

<Javascript with XMLHttpRequest>
document.getElementById('spanFileSizeText').innerHTML=updateSize("inputFileUpload");
</XMLHttpRequest>

If the above solution does not work for you, try this:

#1.1 Do NOT ignore file pattern in  any subdirectory
!*/config.php
#1.2 ...only ignore it in the current directory
/config.php

# 2.1 Ignore file pattern everywhere
config.php
# 2.2 ...but NOT in the current directory

Make sure you are in the project directory before running bundle install. For example, after running rails new myproject, you will want to cd myproject before running bundle install.

You need to dig a bit deeper into the api to do this:

from matplotlib import pyplot as plt
plt.plot(range(5))
plt.xlim(-3, 3)
plt.ylim(-3, 3)
plt.gca().set_aspect('equal', adjustable='box')
plt.draw()

doc for set_aspect

On our site we have pages where the content is static, and pages where it is loaded in with AJAX. On one page (a search page), there were cases when the AJAX results would more than fill the page, and cases where it would return no results. In order for the background image to fill the page in all cases we had to apply the following CSS:

html {
   margin: 0px;
   height: 100%;
   width: 100%;
}

body {
   margin: 0px;
   min-height: 100%;
   width: 100%;
}

height for the html and min-height for the body.

explorer .

This is a dual problem (as many in the world wide web world).

You need to evaluate if the browser supports html5 (I use Modernizr to do it). In this case if you have a normal form the browser will do the job for you, but if you need ajax/json (as many of everyday case) you need to perform manual verification anyway.

.. so, my suggestion is to use a regular expression to evaluate anytime before submit. The expression I use is the following:

var email = /^[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$/;

This one is taken from http://www.regular-expressions.info/ . This is a hard world to understand and master, so I suggest you to read this page carefully.

Did you set the CSS:

html, body
{
    height: 100%;
}

You need this to be able to make the div take up all the space. :)

You can use ~ like {{ foo ~ 'inline string' ~ bar.fieldName }}

But you can also create your own concat function to use it like in your question:
{{ concat('http://', app.request.host) }}:

In src/AppBundle/Twig/AppExtension.php

<?php

namespace AppBundle\Twig;

class AppExtension extends \Twig_Extension
{
    /**
     * {@inheritdoc}
     */
    public function getFunctions()
    {
        return [
            new \Twig_SimpleFunction('concat', [$this, 'concat'], ['is_safe' => ['html']]),
        ];
    }

    public function concat()
    {
        return implode('', func_get_args())
    }

    /**
     * {@inheritdoc}
     */
    public function getName()
    {
        return 'app_extension';
    }
}

In app/config/services.yml:

services:
    app.twig_extension:
        class: AppBundle\Twig\AppExtension
        public: false
        tags:
            - { name: twig.extension }

As .Net progresses, so does their ability to add new 32-bit configurations that trips everyone up it seems.

If you are on .Net Framework 4.7.2 do the following:

Go to Project Properties

Build

Uncheck 'prefer 32-bit'

Cheers!

Note that if strings has spaces then quotation marks are needed at definition and must be chopped while concatenating:

rem The retail files set
set FILES_SET="(*.exe *.dll"

rem The debug extras files set
set DEBUG_EXTRA=" *.pdb"

rem Build the DEBUG set without any
set FILES_SET=%FILES_SET:~1,-1%%DEBUG_EXTRA:~1,-1%

rem Append the closing bracket
set FILES_SET=%FILES_SET%)

echo %FILES_SET%

Cheers...

%~dp0 expands to current directory path of the running batch file.

To get clear understanding, let's create a batch file in a directory.

C:\script\test.bat

with contents:

@echo off
echo %~dp0

When you run it from command prompt, you will see this result:

C:\script\

You can using option --data with file.

Write xml content to a file named is soap_get.xml and using curl command to send request:

curl -X POST --header "Content-Type:text/xml;charset=UTF-8" --data @soap_get.xml your_url

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

Selenium answers this question in their DESCRIPTION.rst file:

Drivers
=======

Selenium requires a driver to interface with the chosen browser. Firefox, for example, requires geckodriver <https://github.com/mozilla/geckodriver/releases>_, which needs to be installed before the below examples can be run. Make sure it's in your PATH, e. g., place it in /usr/bin or /usr/local/bin.

Failure to observe this step will give you an error `selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

Basically just download the geckodriver, unpack it and move the executable to your /usr/bin folder.

You can use Date.getTime() function, or the Date object itself which when divided returns the time in milliseconds.

var d = new Date();

d/1000
> 1510329641.84

d.getTime()/1000
> 1510329641.84

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

type "my.cnf" and hit search.

Where it is documented:

From the API documentation under the has_many association in "Module ActiveRecord::Associations::ClassMethods"

collection.build(attributes = {}, …) Returns one or more new objects of the collection type that have been instantiated with attributes and linked to this object through a foreign key, but have not yet been saved. Note: This only works if an associated object already exists, not if it‘s nil!

The answer to building in the opposite direction is a slightly altered syntax. In your example with the dogs,

Class Dog
   has_many :tags
   belongs_to :person

Class Person

d = Dog.new
d.build_person(:attributes => "go", :here => "like normal")

or even

t = Tag.new
t.build_dog(:name => "Rover", :breed => "Maltese")

You can also use create_dog to have it saved instantly (much like the corresponding "create" method you can call on the collection)

How is rails smart enough? It's magic (or more accurately, I just don't know, would love to find out!)

In your CSS add this:

input {-webkit-appearance: none; box-shadow: none !important; }
:-webkit-autofill { color: #fff !important; }

Only for Chrome! :)

Declare your activity in the manifest like this:

 <activity   
     android:name=".yourActivity"    
     android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>

And add a transparent background to your layout.

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

Showing it graphically.

Centering on parent is done by constraining both sides to the parent. You can the constrain additional objects off of the centered object.

Note. Each arrow represents a "app:layout_constraintXXX_toYYY=" attribute. (6 in the picture)

Adding to the other excellent posts.

Sometimes you don't want to specify the number of arguments and want to use keys for them (the compiler will complain if one argument passed in a dictionary is not used in the method).

def manyArgs1(args):
  print args.a, args.b #note args.c is not used here

def manyArgs2(args):
  print args.c #note args.b and .c are not used here

class Args: pass

args = Args()
args.a = 1
args.b = 2
args.c = 3

manyArgs1(args) #outputs 1 2
manyArgs2(args) #outputs 3

Then you can do things like

myfuns = [manyArgs1, manyArgs2]
for fun in myfuns:
  fun(args)

• Open Solution file (.sln) in Editable mode (Notepad or notepad++ or any other tool)

cd has a parameter /d, which will change drive and path with one command:

cd /d d:\temp

( see cd /?)

This works in both SQL 2005 and 2008:

declare @source varbinary(max);
set @source = 0x21232F297A57A5A743894A0E4A801FC3;
select cast('' as xml).value('xs:hexBinary(sql:variable("@source"))', 'varchar(max)');

Get yourself a 64-bit JVM from Oracle.

Building on and updating a number of earlier responses (thanks: SilentGhost, nosklo, Ramkumar) a simple portable timer would use timeit's default_timer():

>>> import timeit
>>> tic=timeit.default_timer()
>>> # Do Stuff
>>> toc=timeit.default_timer()
>>> toc - tic #elapsed time in seconds

This will return the elapsed wall clock (real) time, not CPU time. And as described in the timeit documentation chooses the most precise available real-world timer depending on the platform.

ALso, beginning with Python 3.3 this same functionality is available with the time.perf_counter performance counter. Under 3.3+ timeit.default_timer() refers to this new counter.

For more precise/complex performance calculations, timeit includes more sophisticated calls for automatically timing small code snippets including averaging run time over a defined set of repetitions.

VLookup

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

All you need just run a test wait till finish, after that go to Build Setting, Search in to Build Setting Inference, change swift 3 @objc Inference to (Default). that's all what i did and worked perfect.

Before you begin, if you are uncomfortable with a command line, you can do all the following steps using SourceTree, GitExtension, GitHub Desktop, or your favorite tool.

To solve the issue, you might have two scenarios:

1) Fix only remote repository branch which is behind commit

Example: Both branches are on the remote side

ahead === Master branch

behind === Develop branch

Solution:

1. Clone the repository to the local workspace: this will give you the Master branch which is ahead with commit

   git clone repositoryUrl
   

2. Create a branch with Develop name and checkout to that branch locally

   git checkout -b DevelopBranchName // this command creates and checkout the branch
   

3. Pull from the remote Develop branch. Conflict might occur. if so, fix the conflict and commit the changes.

    git pull origin DevelopBranchName
   

4. Merge the local Develop branch with the remote Develop branch

     git merge origin develop
   

5. Push the merged branch to the remote Develop branch

     git push origin develop
   

2) Local Master branch is behind the remote Master branch

This means every locally created branch is behind.

Before preceding, you have to commit or stash all the changes you made on the branch that is behind commits.

Solution:

1. Checkout your local Master branch

   git checkout master
   

2. Pull from remote Master branch

   git pull origin master
   

Now your local Master is in sync with the remote Branch but other local branches, that branched from the local Master branch, are not in sync with your local Master branch because of the above command. To fix that:

1. Checkout the branch that is behind your local Master branch

   git checkout BranchNameBehindCommit
   

2. Merge with the local Master branch

   git merge master  // Now your branch is in sync with local Master branch
   

If this branch is on the remote repository, you have to push your changes

    git push origin branchBehindCommit

It is possible the other branch you try to pull from is out of synch; so before adding and removing remote try to (if you are trying to pull from master)

git pull origin master

for me that simple call solved those error messages:

• fatal: 'master' does not appear to be a git repository
• fatal: Could not read from remote repository.

Try this

df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

This works for me

You could try installing the 32 bit version of opencv

If you want to stop tracking file without deleting the file from your local system, which I prefer for ignoring config/database.yml file. Simply try:

git rm --cached config/database.yml
# this will delete your file from git history but not from your local system.

now, add this file to .gitignore file and commit the changes. And from now on, any changes made to config/database.yml will not get tracked by git.

$ echo config/database.yml >> .gitignore

Thanks

Separate it into 2 triggers. One for the deletion and one for the insertion\ update.

As I challenge I decided to test how far can one go with platform-independent (hopefully) template trickery.

The names are assembled completely at compilation time. (Which means typeid(T).name() couldn't be used, thus you have to explicitly provide names for non-compound types. Otherwise placeholders will be displayed instead.)

Example usage:

TYPE_NAME(int)
TYPE_NAME(void)
// You probably should list all primitive types here.

TYPE_NAME(std::string)

int main()
{
    // A simple case
    std::cout << type_name<void(*)(int)> << '\n';
    // -> `void (*)(int)`

    // Ugly mess case
    // Note that compiler removes cv-qualifiers from parameters and replaces arrays with pointers.
    std::cout << type_name<void (std::string::*(int[3],const int, void (*)(std::string)))(volatile int*const*)> << '\n';
    // -> `void (std::string::*(int *,int,void (*)(std::string)))(volatile int *const*)`

    // A case with undefined types
    //  If a type wasn't TYPE_NAME'd, it's replaced by a placeholder, one of `class?`, `union?`, `enum?` or `??`.
    std::cout << type_name<std::ostream (*)(int, short)> << '\n';
    // -> `class? (*)(int,??)`
    // With appropriate TYPE_NAME's, the output would be `std::string (*)(int,short)`.
}

HttpClient.get() applies res.json() automatically and returns Observable<HttpResponse<string>>. You no longer need to call this function yourself.

Try this. It uses the split function which is a core part of javascript, nothing to do with jQuery.

var parts = html.split(":-"),
    i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
    $("#" + parts[i]).text(parts[i + 1]);
}

The traditional way to transform a string to a UTF-8 string is as follows:

StrConv("hello world",vbFromUnicode)

So put simply:

Dim fnum As Integer
fnum = FreeFile
Open "myfile.txt" For Output As fnum
Print #fnum, StrConv("special characters: äöüß", vbFromUnicode)
Close fnum

No special COM objects required

I would recommend checking out Otto, an EventBus tailored specifically to Android. Your Activity/UI can listen to events posted on the Bus from the Service, and decouple itself from the backend.

You could translate spaces to newlines and then grep, e.g.:

cat * | tr ' ' '\n' | grep th

Not sure if this matters to anyone else, but I prefer the id for the table to be the first column in the database. The syntax for that is:

ALTER TABLE your_db.your_table ADD COLUMN `id` int(10) UNSIGNED PRIMARY KEY AUTO_INCREMENT FIRST;

Which is just a slight improvement over the first answer. If you wanted it to be in a different position, then

ALTER TABLE unique_address ADD COLUMN `id` int(10) UNSIGNED PRIMARY KEY AUTO_INCREMENT AFTER some_other_column;

Another code sample to convert a real/float to an integer using variables. "vel" is a real/float number and converted to the next highest INTEGER, "newvel".

import arcpy.math, os, sys, arcpy.da
.
.
with arcpy.da.SearchCursor(densifybkp,[floseg,vel,Length]) as cursor:
 for row in cursor:
    curvel = float(row[1])
    newvel = int(math.ceil(curvel))

1.- How do I get mysql prompt in linux terminal?

mysql -u root -p

At the Enter password: prompt, well, enter root's password :)

You can find further reference by typing mysql --help or at the online manual.

2. How I stop the mysql server from linux terminal?

It depends. Red Hat based distros have the service command:

service mysqld stop

Other distros require to call the init script directly:

/etc/init.d/mysqld stop

3. How I start the mysql server from linux terminal?

Same as #2, but with start.

4. How do I get mysql prompt in linux terminal?

Same as #1.

5. How do I login to mysql server from linux terminal?

Same as #1.

6. How do I solve following error?

Same as #1.

If you are using this module with Python3 and having trouble with import. try this.

pip uninstall crypto
pip uninstall pycryptodome
pip install pycryptodome

Good Luck!

One way I can imagine is to use a linked list to implement such a scenario, if you need all the numbers entered before the user enters something which indicates the loop termination. (posting as the first option, because have never done this for user input, it just seemed to be interesting. Wasteful but artistic)

Another way is to do buffered input. Allocate a buffer, fill it, re-allocate, if the loop continues (not elegant, but the most rational for the given use-case).

I don't consider the described to be elegant though. Probably, I would change the use-case (the most rational).

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

Check the project properties. It's configurable there if you are using another .net windows application for example

If you need to re-use a string, then use StringBuffer:

String str = "hi";
StringBuffer sb = new StringBuffer(str);
while (...) {
    sb.setCharAt(1, 'k');
}

EDIT:

Note that StringBuffer is thread-safe, while using StringBuilder is faster, but not thread-safe.

Update: as of the day of this writing, namedTuples are pickable (starting with python 2.7)

The issue here is the child processes aren't able to import the class of the object -in this case, the class P-, in the case of a multi-model project the Class P should be importable anywhere the child process get used

a quick workaround is to make it importable by affecting it to globals()

globals()["P"] = P

Left bit shifting to multiply by any power of two and right bit shifting to divide by any power of two.

For example, x = x * 2; can also be written as x<<1 or x = x*8 can be written as x<<3 (since 2 to the power of 3 is 8). Similarly x = x / 2; is x>>1 and so on.

It's been a while since your question, but ... Have you tried setting the Audio stream type?

mp.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);

It must be done before prepare.

This works too

 var i = 1;_x000D_
 $('button').click(function() {_x000D_
     $('#red').clone().appendTo('#test').prop('id', 'red' + i);_x000D_
     i++; _x000D_
 });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>_x000D_
<div id="test">_x000D_
  <button>Clone</button>_x000D_
  <div class="red" id="red">_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<style>_x000D_
  .red {_x000D_
    width:20px;_x000D_
    height:20px;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
  }_x000D_
</style>

Apart from the options already given in other answers, there's a current more active, recent and open-source project called pygubu.

This is the first description by the author taken from the github repository:

Pygubu is a RAD tool to enable quick & easy development of user interfaces for the python tkinter module.

The user interfaces designed are saved as XML, and by using the pygubu builder these can be loaded by applications dynamically as needed. Pygubu is inspired by Glade.

Pygubu hello world program is an introductory video explaining how to create a first project using Pygubu.

The following in an image of interface of the last version of pygubu designer on a OS X Yosemite 10.10.2:

I would definitely give it a try, and contribute to its development.

I encountered this problem because the dataset was filtered wrongly and the resultant data frame was empty. Even the following caused the error to show:

ggplot(df, aes(x="", y = y, fill=grp))

because df was empty.

I don't why you would put a<p>element there. But another way of removing spaces in between the paragraphs is by declaring only one paragraph

<ul>
   <p><li>HI THERE</li>
    <br>
    <li>ME</li>
     </p>
   </ul>

i tried that successful.

scrollView.postDelayed(new Runnable() {
    @Override
    public void run() {
        scrollView.smoothScrollTo(0, scrollView.getHeight());
    }
}, 1000);

Alter TABLE `tableName` MODIFY COLUMN `ColumnName` datatype(length);

Ex :

Alter TABLE `tbl_users` MODIFY COLUMN `dup` VARCHAR(120);

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

Try xcorr, it's a built-in function in MATLAB for cross-correlation:

c = xcorr(A_1, A_2);

However, note that it requires the Signal Processing Toolbox installed. If not, you can look into the corrcoef command instead.

I have found a solution in Python that is working well !

from math import atan2,degrees

def GetAngleOfLineBetweenTwoPoints(p1, p2):
    return degrees(atan2(p2 - p1, 1))

print GetAngleOfLineBetweenTwoPoints(1,3)

Try something similar to this:

#include <stdio.h>
#include <string.h>

int main(int argc, const char * argv[])
{
  // Insert code here...
  char firstname[100], secondname[100];
  printf("Enter First Name: ");
  fgets(firstname, 100, stdin);
  printf("Enter Second Name: ");
  fgets(secondname,100,stdin);
  firstname[strlen(firstname)-1]= '\0';
  printf("fullname is %s %s", firstname, secondname);

  return 0;
}

First you will need to install node definitions for Typescript. You can find the definitions file here:

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/node/node.d.ts

Once you've got file, just add the reference to your .ts file like this:

/// <reference path="path/to/node.d.ts" />

Then you can code your typescript class that read/writes, using the Node File System module. Your typescript class myClass.ts can look like this:

/// <reference path="path/to/node.d.ts" />

class MyClass {

    // Here we import the File System module of node
    private fs = require('fs');

    constructor() { }

    createFile() {

        this.fs.writeFile('file.txt', 'I am cool!',  function(err) {
            if (err) {
                return console.error(err);
            }
            console.log("File created!");
        });
    }

    showFile() {

        this.fs.readFile('file.txt', function (err, data) {
            if (err) {
                return console.error(err);
            }
            console.log("Asynchronous read: " + data.toString());
        });
    }
}

// Usage
// var obj = new MyClass();
// obj.createFile();
// obj.showFile();

Once you transpile your .ts file to a javascript (check out here if you don't know how to do it), you can run your javascript file with node and let the magic work:

> node myClass.js

org.springframework.util.CollectionUtils

boolean containsAny(java.util.Collection<?> source, java.util.Collection<?> candidates)

Return true if any element in 'candidates' is contained in 'source'; otherwise returns false

Try This

var player:AVPlayer!
var avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.frame = CGRectMake(your frame)
self.view.layer .addSublayer(avPlayerLayer)
var steamingURL:NSURL = NSURL(string:playerURL)
player = AVPlayer(URL: steamingURL)
player.play()

In Case your running nodemon for the node version 12 ,use this command. server.js is the "main" inside package.json file ,replace it with relevant file inside your package.json file

nodemon --experimental-modules server.js

Or simply use the JFreechart library - http://www.jfree.org/jfreechart/ .

If you use UPPER(text), the like '%lah%' will always return zero results. Use '%LAH%'.

A slight riff on the top voted answer that I found to be a little more explicit is to use the jekyll syntax for adding a class to something and then style it that way.

So in the post you would have:

![My image](/images/my-image.png)

{:.image-caption}
*The caption for my image*

And then in your CSS file you can do something like this:

.image-caption {
  text-align: center;
  font-size: .8rem;
  color: light-grey;

Comes out looking good!

If nothing works then add authentication mode="Windows" in your system.web attribute in your Web.Config file. hope it will work for you.

GRANT ALL ON *.* to user@'%' IDENTIFIED BY 'password'; 

Will allow a specific user to log on from anywhere.

It's bad because it removes some security control, i.e. if an account is compromised.

The EOF pattern needs a prime read to 'bootstrap' the EOF checking process. Consider the empty file will not initially have its EOF set until the first read. The prime read will catch the EOF in this instance and properly skip the loop completely.

What you need to remember here is that you don't get the EOF until the first attempt to read past the available data of the file. Reading the exact amount of data will not flag the EOF.

I should point out if the file was empty your given code would have printed since the EOF will have prevented a value from being set to x on entry into the loop.

• 0

So add a prime read and move the loop's read to the end:

int x;

iFile >> x; // prime read here
while (!iFile.eof()) {
    cerr << x << endl;
    iFile >> x;
}
