I encountered a lot of problems when using jaxb in Maven but i managed to solve your problem by doing the following

First create a schema.xjc file

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
               xmlns:xsd="http://www.w3.org/2001/XMLSchema"
               jaxb:version="2.0">
    <jaxb:bindings schemaLocation="YOUR_URL?wsdl#types?schema1">
        <jaxb:schemaBindings>
            <jaxb:package name="your.package.name.schema1"/>
        </jaxb:schemaBindings>
    </jaxb:bindings>
    <jaxb:bindings schemaLocation="YOUR_URL??wsdl#types?schema2">
        <jaxb:schemaBindings>
            <jaxb:package name="your.package.name.schema2"/>
        </jaxb:schemaBindings>
    </jaxb:bindings>
</jaxb:bindings>

The package name can be anything you want it to be, as long as it doesn't contain any reserved keywords in Java

Next you have to create the wsimport.bat script to generate your packaged and code at the preferred location.

cd C:\YOUR\PATH\TO\PLACE\THE\PACKAGES
wsimport -keep -verbose -b "C:\YOUR\PATH\TO\schema.xjb" YOUR_URL?wsdl
pause

If you do not want to use cd, you can put the wsimport.bat in "C:\YOUR\PATH\TO\PLACE\THE\PACKAGES"

If you run it without -keep -verbose it will only generate the packages but not the .java files.

The -b will make sure the schema.xjc is used when generating

there are three ways you can use: the RETURN value, and OUTPUT parameter and a result set

ALSO, watch out if you use the pattern: SELECT @Variable=column FROM table ...

if there are multiple rows returned from the query, your @Variable will only contain the value from the last row returned by the query.

RETURN VALUE
since your query returns an int field, at least based on how you named it. you can use this trick:

CREATE PROCEDURE GetMyInt
( @Param int)
AS
DECLARE @ReturnValue int

SELECT @ReturnValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN @ReturnValue
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC @SelectedValue = GetMyInt @Param
PRINT @SelectedValue

this will only work for INTs, because RETURN can only return a single int value and nulls are converted to a zero.

OUTPUT PARAMETER
you can use an output parameter:

CREATE PROCEDURE GetMyInt
( @Param     int
 ,@OutValue  int OUTPUT)
AS
SELECT @OutValue=MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

and now call your procedure like:

DECLARE @SelectedValue int
       ,@Param         int
SET @Param=1
EXEC GetMyInt @Param, @SelectedValue OUTPUT
PRINT @SelectedValue 

Output parameters can only return one value, but can be any data type

RESULT SET for a result set make the procedure like:

CREATE PROCEDURE GetMyInt
( @Param     int)
AS
SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = @Param
RETURN 0
GO

use it like:

DECLARE @ResultSet table (SelectedValue int)
DECLARE @Param int
SET @Param=1
INSERT INTO @ResultSet (SelectedValue)
    EXEC GetMyInt @Param
SELECT * FROM @ResultSet 

result sets can have many rows and many columns of any data type

I needed to calculate the elapsed and remaining time to show a progress-bar. It was not easy using the accepted answer. 'setInterval' is better than 'setTimeout' for this task. So, I created this Timer class that you can use in any project.

https://jsfiddle.net/ashraffayad/t0mmv853/

'use strict';


    //Constructor
    var Timer = function(cb, delay) {
      this.cb = cb;
      this.delay = delay;
      this.elapsed = 0;
      this.remaining = this.delay - self.elapsed;
    };

    console.log(Timer);

    Timer.prototype = function() {
      var _start = function(x, y) {
          var self = this;
          if (self.elapsed < self.delay) {
            clearInterval(self.interval);
            self.interval = setInterval(function() {
              self.elapsed += 50;
              self.remaining = self.delay - self.elapsed;
              console.log('elapsed: ' + self.elapsed, 
                          'remaining: ' + self.remaining, 
                          'delay: ' + self.delay);
              if (self.elapsed >= self.delay) {
                clearInterval(self.interval);
                self.cb();
              }
            }, 50);
          }
        },
        _pause = function() {
          var self = this;
          clearInterval(self.interval);
        },
        _restart = function() {
          var self = this;
          self.elapsed = 0;
          console.log(self);
          clearInterval(self.interval);
          self.start();
        };

      //public member definitions
      return {
        start: _start,
        pause: _pause,
        restart: _restart
      };
    }();


    // - - - - - - - - how to use this class

    var restartBtn = document.getElementById('restart');
    var pauseBtn = document.getElementById('pause');
    var startBtn = document.getElementById('start');

    var timer = new Timer(function() {
      console.log('Done!');
    }, 2000);

    restartBtn.addEventListener('click', function(e) {
      timer.restart();
    });
    pauseBtn.addEventListener('click', function(e) {
      timer.pause();
    });
    startBtn.addEventListener('click', function(e) {
      timer.start();
    });

To convert the string into a date object:

from datetime import date, datetime

date_string = "01/12/2011"
date_object = date(*map(int, reversed(date_string.split("/"))))
assert date_object == datetime.strptime(date_string, "%d/%m/%Y").date()

The way to convert the date object into POSIX timestamp depends on timezone. From Converting datetime.date to UTC timestamp in Python:

• date object represents midnight in UTC

  import calendar
  
  timestamp1 = calendar.timegm(utc_date.timetuple())
  timestamp2 = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * 24*60*60
  assert timestamp1 == timestamp2
  

• date object represents midnight in local time

  import time
  
  timestamp3 = time.mktime(local_date.timetuple())
  assert timestamp3 != timestamp1 or (time.gmtime() == time.localtime())
  

The timestamps are different unless midnight in UTC and in local time is the same time instance.

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

You need to declare your event in the class from myObject :

public event EventHandler<EventArgs> myMethod; //you should name it as an event, like ObjectChanged.

then myNameEvent is the callback to handle the event, and it can be in any other class

I think I got this from not explicitly deleting some tables from the edmx before renaming and re-adding them. Instead, I just renamed the tables and then did an Update Model from Database, thinking it would see them gone, and delete them from model. I then did another Update Model from Database and added the renamed tables.

The site was working with the new tables, but I had the error. Eventually, I noticed the original tables were still in the model. I deleted them from the model (click them in edmx screen, delete key), and then the error went away.

Never tried it, but git help ignore suggests that if you put a .gitignore with *.js in /public/static, it will do what you want.

Note: make sure to also check out Joeys' answer below: if you want to ignore files in a specific subdirectory, then a local .gitignore is the right solution (locality is good). However if you need the same pattern to apply to your whole repo, then the ** solution is better.

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.

However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).

EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:

1. It is a parameter in the response (expires_in)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.

2. There is also an API that returns the remaining lifetime of the access_token:

   https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}

   This will return a json array that will contain an expires_in parameter, which is the number of seconds left in the lifetime of the token.

This is what i used!

public class SMSListener extends BroadcastReceiver {

    // Get the object of SmsManager
    final SmsManager sms = SmsManager.getDefault();
String mobile,body;

    public void onReceive(Context context, Intent intent) {

        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();

        try {

            if (bundle != null) {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");

                for (int i = 0; i < pdusObj.length; i++) {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                     mobile=senderNum.replaceAll("\\s","");
                     body=message.replaceAll("\\s","+");


                    Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + body);


                    // Show Alert
                    int duration = Toast.LENGTH_LONG;
                    Toast toast = Toast.makeText(context,
                            "senderNum: "+ mobile+ ", message: " + message, duration);
                    toast.show();

                } // end for loop
            } // bundle is null

        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" +e);

Using @Marc Gravell 's answer, I found a way to use the following method:

source.TakeWhile(x => x != value).Count();

in order to get -1 when the item cannot be found:

internal static class Utils
{

    public static int IndexOf<T>(this IEnumerable<T> enumerable, T item) => enumerable.IndexOf(item, EqualityComparer<T>.Default);

    public static int IndexOf<T>(this IEnumerable<T> enumerable, T item, EqualityComparer<T> comparer)
    {
        int index = enumerable.TakeWhile(x => comparer.Equals(x, item)).Count();
        return index == enumerable.Count() ? -1 : index;
    }
}

I guess this way could be both the fastest and the simpler. However, I've not tested performances yet.

Use this

dataTable.Columns["OldColumnName"].ColumnName = "NewColumnName";

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

If you want the value from cell then you don't have to recreate cell in the didSelectRowAtIndexPath

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    println(tasks[indexPath.row])
}

Task would be as follows :

let tasks=["Short walk",
    "Audiometry",
    "Finger tapping",
    "Reaction time",
    "Spatial span memory"
]

also you have to check the cellForRowAtIndexPath you have to set identifier.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as UITableViewCell
    var (testName) = tasks[indexPath.row]
    cell.textLabel?.text=testName
    return cell
}

Hope it helps.

BDD style:

import static org.mockito.BDDMockito.given;
        ...

        given(yourMock.yourMethod()).willReturn(1, 2, 3);

        when(yourMock.yourMethod()).thenReturn(1, 2, 3);

Keep in mind, in the general case you could have multiple NAT translations going on, and multiple dns servers, each operating on different NAT translation levels.

What if you have carrier grade NAT, and want to communicate with other customers of the same carrier? In the general case you never know for sure because you might appear with different host names at every NAT translation.

Slice notation a[start_index:end_index:step]

return a[::2]

where start_index defaults to 0 and end_index defaults to the len(a).

This answer is from 2009. Now a community wiki in case anybody cares to bring it up-to-date.

IE needs a plugin to display SVG. Most common is the one available for download by Adobe; however, Adobe no longer supports or develops it. Firefox, Opera, Chrome, Safari, will all display basic SVG fine but will run into quirks if advanced features are used, as support is incomplete. Firefox has no support for declarative animation.

SVG elements can be created with javascript as follows:

// "circle" may be any tag name
var shape = document.createElementNS("http://www.w3.org/2000/svg", "circle");
// Set any attributes as desired
shape.setAttribute("cx", 25);
shape.setAttribute("cy", 25);
shape.setAttribute("r",  20);
shape.setAttribute("fill", "green");
// Add to a parent node; document.documentElement should be the root svg element.
// Acquiring a parent element with document.getElementById() would be safest.
document.documentElement.appendChild(shape);

The SVG specification describes the DOM interfaces for all SVG elements. For example, the SVGCircleElement, which is created above, has cx, cy, and r attributes for the center point and radius, which can be directly accessed. These are the SVGAnimatedLength attributes, which have a baseVal property for the normal value, and an animVal property for the animated value. Browsers at the moment are not reliably supporting the animVal property. baseVal is an SVGLength, whose value is set by the value property.

Hence, for script animations, one can also set these DOM properties to control SVG. The following code should be equivalent to the above code:

var shape = document.createElementNS("http://www.w3.org/2000/svg", "circle");
shape.cx.baseVal.value = 25;
shape.cy.baseVal.value = 25;
shape.r.baseVal.value = 20;
shape.setAttribute("fill", "green");
document.documentElement.appendChild(shape);

I use SimpleJpaRepository as the base class of repository implementation and add custom method in the interface,eg:

public interface UserRepository  {
    User FindOrInsert(int userId);
}

@Repository
public class UserRepositoryImpl extends SimpleJpaRepository implements UserRepository {

    private RedisClient redisClient;

    public UserRepositoryImpl(RedisClient redisClient, EntityManager em) {
        super(User.class, em);
        this.redisClient = redisClient;
    }


@Override
public User FindOrInsert(int userId) {

    User u = redisClient.getOrSet("test key.. User.class, () -> {
        Optional<User> ou = this.findById(Integer.valueOf(userId));
        return ou.get();
    });
    …………
    return u;
}

I found that the RatingBar stretched to a maximum number of stars because it was enclosed in a Table with the attribute android:stretchColumns = "*".

Once I took stretchCoulumns off all columns, the RatingBar displayed according to the android:numStars value

If you read the message carefully you will see that you are using the permissions like camera, Microphone, Contacts, Storage and Phone, etc. and you don't supply a privacy policy. you need to supply a privacy policy if you do that. you can find more information about the android privacy policy on google

To Add Privacy Policy In-Play Console,

1. Find and select All Apps.

2. Select the application you need to add your Privacy Policy to.

3. Find the Policy at the end of the page.

4. Click App content to edit the listing for your app.

5. Find the field labeled Privacy Policy and place the URL of the page of your Privacy Policy

6. Click Save and you are good to go.

Note: You need to have a public web page to host your Privacy Policy. Google Play Store won't host the policy for you.

For some reason the code supplied by m3z (with the DisplayHtml(string) method) is not working in my case (except first time). I'm always displaying html from string. Here is my version after the battle with the WebBrowser control:

webBrowser1.Navigate("about:blank");
while (webBrowser1.Document == null || webBrowser1.Document.Body == null)
    Application.DoEvents();
webBrowser1.Document.OpenNew(true).Write(html);

Working every time for me. I hope it helps someone.

How to SQLITE in C#

I nearly used everything in that article to create the SQLite database for my own C# Application.

Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.

After you added the reference, refer to the dll from your code using the following line on top of your class:

using System.Data.SQLite;

You can find the dll's here:

SQLite DLL's

You can find the NuGet way here:

NuGet

Up next is the create script. Creating a database file:

SQLiteConnection.CreateFile("MyDatabase.sqlite");

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();

string sql = "create table highscores (name varchar(20), score int)";

SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

sql = "insert into highscores (name, score) values ('Me', 9001)";

command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

m_dbConnection.Close();

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.

Example on how to use transactions:

 using (TransactionScope tran = new TransactionScope())
 {
     //Insert create script here.

     //Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.

Here I found another good option to migrate your MongoDB data to Elasticsearch. A go daemon that syncs mongodb to elasticsearch in realtime. Its the Monstache. Its available at : Monstache

Below the initial setp to configure and use it.

Step 1:

Step 4. Download the "https://github.com/rwynn/monstache/releases". Unzip the download and adjust your PATH variable to include the path to the folder for your platform. GO to cmd and type "monstache -v" # 4.13.1 Monstache uses the TOML format for its configuration. Configure the file for migration named config.toml

Step 5.

Remember that, converting from List to Set will remove duplicates from collection because List supports duplicates but Set does not support duplicates in Java.

Direct Conversion : The most common and simple way to convert a List to a Set

// Creating a list of strings
List<String> list = Arrays.asList("One", "Two", "Three", "Four");

// Converting a list to set
Set<String> set = new HashSet<>(list);

Apache Commons Collections : You may also use the Commons Collections API to convert a List to a Set :-

// Creating a list of strings
List<String> list = Arrays.asList("One", "Two", "Three", "Four");

// Creating a set with the same number of members in the list 
Set<String> set = new HashSet<>(4);

// Adds all of the elements in the list to the target set
CollectionUtils.addAll(set, list);

Using Stream : Another way is to convert given list to stream, then stream to set :-

// Creating a list of strings 
List<String> list = Arrays.asList("One", "Two", "Three", "Four"); 

// Converting to set using stream 
Set<String> set = list.stream().collect(Collectors.toSet()); 

if you are using Maven 2.0.8+, then it will be very simple, run mvndebug from the console, and connect to it via Remote Debug Java Application with port 8000.

In addition: if you show links in listview in fragment, do not create it like this

adapter = new ListAdapter(getActivity().getApplicationContext(),mStrings);

instead call

adapter = new ListAdapter(getActivity(),mStrings);

adapter works fine in both cases, but links work only in last one.

I use this for Windows (binary prefixes):

static readonly string[] BinaryPrefix = { "bytes", "KB", "MB", "GB", "TB" }; // , "PB", "EB", "ZB", "YB"
string GetMemoryString(double bytes)
{
    int counter = 0;
    double value = bytes;
    string text = "";
    do
    {
        text = value.ToString("0.0") + " " + BinaryPrefix[counter];
        value /= 1024;
        counter++;
    }
    while (Math.Floor(value) > 0 && counter < BinaryPrefix.Length);
    return text;
}

Repository selection screen cannot be shown on your system (OS X), since OS X no longer includes X11. R tries to show you the prompt through X11. Install X11 from http://xquartz.macosforge.org/landing/. Then run the install command. The repo selection prompt will be shown.

add style="clear:both;" to the "adm" div.

Another workaround that, depends on the case, it could be useful: creating another bash that inherites the exported variable. It is a particular case of @Keith Thompson answer, will all of those drawbacks.

export.bash:

# !/bin/bash
export VAR="HELLO, VARIABLE"
bash

Now:

./export.bash
echo $VAR

If you are looking for "Better Javascript Mouse Events" which allow for

• left mousedown
• middle mousedown
• right mousedown
• left mouseup
• middle mouseup
• right mouseup
• left click
• middle click
• right click
• mousewheel up
• mousewheel down

Have a look at this cross browser normal javascript which triggers the above events, and removes the headache work. Just copy and paste it into the head of your script, or include it in a file in the <head> of your document. Then bind your events, refer to the next code block below which shows a jquery example of capturing the events and firing the functions assigned to them, though this works with normal javascript binding as well.

If your interested in seeing it work, have a look at the jsFiddle: https://jsfiddle.net/BNefn/

            if (e.which == null) {
                button = (e.button < 2) ? "left" : ((e.button == 4) ? "middle" : "right");
            } else {
                button = (e.which < 2) ? "left" : ((e.which == 2) ? "middle" : "right");

    var MouseWheelEvent = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel";
    addEvent(window, MouseWheelEvent, GetMouseButton);
})();

Better Mouse Click Events Example (uses jquery for simplicity, but the above will work cross browser and fire the same event names, IE uses on before the names)

<div id="Test"></div>
<script type="text/javascript">
    $('#Test').on('mouseup',function(e){$(this).append(e.type+'<br />');})
              .on('mouseup:left',function(e){$(this).append(e.type+'<br />');})
              .on('mouseup:middle',function(e){$(this).append(e.type+'<br />');})
              .on('mouseup:right',function(e){$(this).append(e.type+'<br />');})

              .on('click',function(e){$(this).append(e.type+'<br />');})
              .on('click:left',function(e){$(this).append(e.type+'<br />');})
              .on('click:middle',function(e){$(this).append(e.type+'<br />');})
              .on('click:right',function(e){$(this).append(e.type+'<br />');})

              .on('mousedown',function(e){$(this).html('').append(e.type+'<br />');})
              .on('mousedown:left',function(e){$(this).append(e.type+'<br />');})
              .on('mousedown:middle',function(e){$(this).append(e.type+'<br />');})
              .on('mousedown:right',function(e){$(this).append(e.type+'<br />');})

              .on('mousewheel',function(e){$(this).append(e.type+'<br />');})
              .on('mousewheel:up',function(e){$(this).append(e.type+'<br />');})
              .on('mousewheel:down',function(e){$(this).append(e.type+'<br />');})
              ;
</script>

And for those who are in need of the minified version...

!function(){function e(e){e=window.event||e;var t="";if("mousedown"==e.type||"click"==e.type||"contextmenu"==e.type||"mouseup"==e.type)t=null==e.which?e.button<2?"left":4==e.button?"middle":"right":e.which<2?"left":2==e.which?"middle":"right";else{var n=e.detail?-120*e.detail:e.wheelDelta;switch(n){case 120:case 240:case 360:t="up";break;case-120:case-240:case-360:t="down"}}var c=e.type;switch("contextmenu"==e.type&&(c="click"),"DOMMouseScroll"==e.type&&(c="mousewheel"),t){case"contextmenu":case"left":case"middle":case"up":case"down":case"right":document.createEvent?(event=new Event(c+":"+t),e.target.dispatchEvent(event)):(event=document.createEventObject(),e.target.fireEvent("on"+c+":"+t,event))}}var t=function(e,t,n){try{e.addEventListener(t,n,!1)}catch(c){e.attachEvent("on"+t,n)}};t(window,"mousedown",e),t(window,"mouseup",e),t(window,"click",e),t(window,"contextmenu",e);var n=/Firefox/i.test(navigator.userAgent)?"DOMMouseScroll":"mousewheel";t(window,n,e)}();

You're saying you have this:

char array[20]; char string[100];
array[0]='1'; 
array[1]='7'; 
array[2]='8'; 
array[3]='.'; 
array[4]='9';

And you'd like to have this:

string[0]= "178.9"; // where it was stored 178.9 ....in position [0]

You can't have that. A char holds 1 character. That's it. A "string" in C is an array of characters followed by a sentinel character (NULL terminator).

Now if you want to copy the first x characters out of array to string you can do that with memcpy():

memcpy(string, array, x);
string[x] = '\0'; 

It's simple math. Given a number X and a rounding factor N, the formula would be:

round(X / N)*N

Here's one I wrote:

/**
 * Format bytes as human-readable text.
 * 
 * @param bytes Number of bytes.
 * @param si True to use metric (SI) units, aka powers of 1000. False to use 
 *           binary (IEC), aka powers of 1024.
 * @param dp Number of decimal places to display.
 * 
 * @return Formatted string.
 */
function humanFileSize(bytes, si=false, dp=1) {
  const thresh = si ? 1000 : 1024;

  if (Math.abs(bytes) < thresh) {
    return bytes + ' B';
  }

  const units = si 
    ? ['kB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'] 
    : ['KiB', 'MiB', 'GiB', 'TiB', 'PiB', 'EiB', 'ZiB', 'YiB'];
  let u = -1;
  const r = 10**dp;

  do {
    bytes /= thresh;
    ++u;
  } while (Math.round(Math.abs(bytes) * r) / r >= thresh && u < units.length - 1);


  return bytes.toFixed(dp) + ' ' + units[u];
}


console.log(humanFileSize(1551859712))  // 1.4 GiB
console.log(humanFileSize(5000, true))  // 5.0 kB
console.log(humanFileSize(5000, false))  // 4.9 KiB

console.log(humanFileSize(999950, true, 2))  // 999.95 kB
console.log(humanFileSize(999500, true, 0))  // 1 MB

You need to call ShellExecute.

The problem is with Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); this line. The Class qualified name is wrong

It is sqlserver.jdbc not jdbc.sqlserver

There is a slick-looking jQuery plugin that apparently plays nice with Bootstrap called SelectBoxIt (http://gregfranko.com/jquery.selectBoxIt.js/). The thing I like about it is that it allows you to trigger the native select box on whatever OS you are on while still maintaining a consistent styling (http://gregfranko.com/jquery.selectBoxIt.js/#TriggertheNativeSelectBox). Oh how I wish Bootstrap provided this option!

The only downside to this is that it adds another layer of complexity into a solution, and additional work to ensure compatibility with all other plug-ins as they get upgraded/patched over time. I'm also not sure about Bootstrap 3 compatibility. But, this may be a good solution to ensure a consistent look across browsers and OS's.

There is no need to include a bulky library such as Moment.js to fix such a simple issue.

The issue you are facing is not with formatting, but with parsing.

As John Shammas mentions in another answer, the Date constructor (and Date.parse) are picky about the input. Your 2016-01-04 10:34:23 may work in one JavaScript implementation, but not necessarily in the other.

According to the specification of ECMAScript 5.1, Date.parse supports (a simplification of) ISO 8601. That's good news, because your date is already very ISO 8601-like.

All you have to do is change the input format just a little. Swap the space for a T: 2016-01-04T10:34:23; and optionally add a time zone (2016-01-04T10:34:23+01:00), otherwise UTC is assumed.

Its still the same concept, you'll need to setup path variable so that windows is aware of the java executable and u can run it from command prompt conveniently

Details from the java's own page: https://java.com/en/download/help/path.xml That article applies to: •Platform(s): Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, Windows 8, Windows 7, Vista, Windows XP, Windows 10

I use Privoxy and cURL to scrape Tor pages:

<?php
    $ch = curl_init('http://jhiwjjlqpyawmpjx.onion'); // Tormail URL
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
    curl_setopt($ch, CURLOPT_PROXY, "localhost:8118"); // Default privoxy port
    curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
    curl_exec($ch);
    curl_close($ch);
?>

After installing Privoxy you need to add this line to the configuration file (/etc/privoxy/config). Note the space and '.' a the end of line.

forward-socks4a / localhost:9050 .

Then restart Privoxy.

/etc/init.d/privoxy restart

It's actually quiet easy.

The way I do this is by saving a flag in a static variable available to all. Then, when I exit, I set this flag and all my activities check this flag onResume. If the flag is set then I issue the System.exit on that activity.

That way all activities will check for the flag and will close gracefully if the flag is set.

I can't comment but don't want to start a new thread. But this isn't working. A simple round trip:

byte[] b = new byte[]{ 0, 0, 0, -127 };  // 0x00000081
String s = new String(b,StandardCharsets.UTF_8); // UTF8 = 0x0000, 0x0000,  0x0000, 0xfffd
b = s.getBytes(StandardCharsets.UTF_8); // [0, 0, 0, -17, -65, -67] 0x000000efbfbd != 0x00000081

I'd need b[] the same array before and after encoding which it isn't (this referrers to the first answer).

To me, it works this way:

# Creating the ARRAY from Result.
$array=array();

while($row = $result->fetch_array(MYSQL_ASSOC))
{
    # Converting each column to UTF8
    $row = array_map('utf8_encode', $row);
    array_push($array,$row);
}

json_encode($array);

Say if you have an application which has similar functionality as that of mine. Where your app is mostly offline and you want to render the Images one after the other. Then below is the approach that worked for me in React Native version 0.60.

1. First create a folder named Resources/Images and place all your images there.
2. Now create a file named Index.js (at Resources/Images) which is responsible for Indexing all the images in the Reources/Images folder.

const Images = { 'image1': require('./1.png'), 'image2': require('./2.png'), 'image3': require('./3.png') }

3. Now create a Component named ImageView at your choice of folder. One can create functional, class or constant component. I have used Const component. This file is responsible for returning the Image depending on the Index.

import React from 'react';
import { Image, Dimensions } from 'react-native';
import Images from './Index';
const ImageView = ({ index }) => {
    return (
        <Image
            source={Images['image' + index]}
        />
    )
}
export default ImageView;

4. Now from the component wherever you want to render the Static Images dynamically, just use the ImageView component and pass the index.

   < ImageView index={this.qno + 1} />

Object initializers are cool because they allow you to set up a class inline. The tradeoff is that your class cannot be immutable. Consider:

public class Album 
{
    // Note that we make the setter 'private'
    public string Name { get; private set; }
    public string Artist { get; private set; }
    public int Year { get; private set; }

    public Album(string name, string artist, int year)
    {
        this.Name = name;
        this.Artist = artist;
        this.Year = year;
    }
}

If the class is defined this way, it means that there isn't really an easy way to modify the contents of the class after it has been constructed. Immutability has benefits. When something is immutable, it is MUCH easier to determine that it's correct. After all, if it can't be modified after construction, then there is no way for it to ever be 'wrong' (once you've determined that it's structure is correct). When you create anonymous classes, such as:

new { 
    Name = "Some Name",
    Artist = "Some Artist",
    Year = 1994
};

the compiler will automatically create an immutable class (that is, anonymous classes cannot be modified after construction), because immutability is just that useful. Most C++/Java style guides often encourage making members const(C++) or final (Java) for just this reason. Bigger applications are just much easier to verify when there are fewer moving parts.

That all being said, there are situations when you want to be able quickly modify the structure of your class. Let's say I have a tool that I want to set up:

public void Configure(ConfigurationSetup setup);

and I have a class that has a number of members such as:

class ConfigurationSetup {
    public String Name { get; set; }
    public String Location { get; set; }
    public Int32 Size { get; set; }
    public DateTime Time { get; set; }

    // ... and some other configuration stuff... 
}

Using object initializer syntax is useful when I want to configure some combination of properties, but not neccesarily all of them at once. For example if I just want to configure the Name and Location, I can just do:

ConfigurationSetup setup = new ConfigurationSetup {
    Name = "Some Name",
    Location = "San Jose"
};

and this allows me to set up some combination without having to define a new constructor for every possibly permutation.

On the whole, I would argue that making your classes immutable will save you a great deal of development time in the long run, but having object initializer syntax makes setting up certain configuration permutations much easier.

Best way is to change launcher icons separately for both iOS and Android.

Change the icons in iOS and Android module separately. The plugin produces different size icons from the same icon which are distorted.

The browser's native JSON API may not give you back your idOld function after you call JSON.stringify, however, if can stringify your JSON yourself (maybe use Crockford's json2.js instead of browser's API), then if you have a string of JSON e.g.

var person_json = "{ \"age:\" : 20, \"isOld:\": false, isOld: function() { return this.age > 60; } }";

then you can call

eval("(" + person + ")") 

, and you will get back your function in the json object.

I know this has been answered, but I'd like to add my own answer:

using (var reader = new StringReader(multiLineString))
{
    for (string line = reader.ReadLine(); line != null; line = reader.ReadLine())
    {
        // Do something with the line
    }
}

i prefer to create folder his name is Utils and inside create page index that contain what that think you helper by

const findByAttr = (component,attr) => {
    const wrapper=component.find(`[data-test='${attr}']`);
    return wrapper;
}

const FUNCTION_NAME = (component,attr) => {
    const wrapper=component.find(`[data-test='${attr}']`);
    return wrapper;
}

export {findByAttr, FUNCTION_NAME}

When you need to use this it should be imported as use "{}" because you did not use the default keyword look

 import {FUNCTION_NAME,findByAttr} from'.whare file is store/utils/index'

you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function

Here is how a UTF8 text file can be read from a zip archive into a string variable (.NET Framework 4.5 and up):

string zipFileFullPath = "{{TypeYourZipFileFullPathHere}}";
string targetFileName = "{{TypeYourTargetFileNameHere}}";
string text = new string(
            (new System.IO.StreamReader(
             System.IO.Compression.ZipFile.OpenRead(zipFileFullPath)
             .Entries.Where(x => x.Name.Equals(targetFileName,
                                          StringComparison.InvariantCulture))
             .FirstOrDefault()
             .Open(), Encoding.UTF8)
             .ReadToEnd())
             .ToArray());

 if (e.attr("name") == "firstName" ) {
     $("#firstName__validate").text($(error).text());
     console.log($(error).html());
 }

Try this get text of error object

EDIT: You say "I am concatenating simple and short XML file and I do not use serialization, so I need to explicitly escape XML character by hand".

I would strongly advise you not to do it by hand. Use the XML APIs to do it all for you - read in the original files, merge the two into a single document however you need to (you probably want to use XmlDocument.ImportNode), and then write it out again. You don't want to write your own XML parsers/formatters. Serialization is somewhat irrelevant here.

If you can give us a short but complete example of exactly what you're trying to do, we can probably help you to avoid having to worry about escaping in the first place.

Original answer

It's not entirely clear what you mean, but normally XML APIs do this for you. You set the text in a node, and it will automatically escape anything it needs to. For example:

LINQ to XML example:

using System;
using System.Xml.Linq;

class Test
{
    static void Main()
    {
        XElement element = new XElement("tag",
                                        "Brackets & stuff <>");

        Console.WriteLine(element);
    }
}

DOM example:

using System;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement element = doc.CreateElement("tag");
        element.InnerText = "Brackets & stuff <>";
        Console.WriteLine(element.OuterXml);
    }
}

Output from both examples:

<tag>Brackets &amp; stuff &lt;&gt;</tag>

That's assuming you want XML escaping, of course. If you're not, please post more details.

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

For some reason I couldn't get danorton's answer to work, I could see what it was supposed to do so I tweaked it a little bit to this:

$('#foo').css('display', 'none').height();
$('#foo').css('display', 'block');

and it worked for me.

There are two general approaches here:

• Check each array item for nan and take any.
• Apply some cumulative operation that preserves nans (like sum) and check its result.

While the first approach is certainly the cleanest, the heavy optimization of some of the cumulative operations (particularly the ones that are executed in BLAS, like dot) can make those quite fast. Note that dot, like some other BLAS operations, are multithreaded under certain conditions. This explains the difference in speed between different machines.

import numpy
import perfplot


def min(a):
    return numpy.isnan(numpy.min(a))


def sum(a):
    return numpy.isnan(numpy.sum(a))


def dot(a):
    return numpy.isnan(numpy.dot(a, a))


def any(a):
    return numpy.any(numpy.isnan(a))


def einsum(a):
    return numpy.isnan(numpy.einsum("i->", a))


perfplot.show(
    setup=lambda n: numpy.random.rand(n),
    kernels=[min, sum, dot, any, einsum],
    n_range=[2 ** k for k in range(20)],
    logx=True,
    logy=True,
    xlabel="len(a)",
)

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

Here is a one-liner: str.replace(/[|\\{}()[\]^$+*?.]/g, '\\$&')

I got it from the escape-string-regexp NPM module.

Trying it out:

escapeStringRegExp.matchOperatorsRe = /[|\\{}()[\]^$+*?.]/g;
function escapeStringRegExp(str) {
    return str.replace(escapeStringRegExp.matchOperatorsRe, '\\$&');
}

console.log(new RegExp(escapeStringRegExp('example.com')));
// => /example\.com/

Using tagged template literals with flags support:

function str2reg(flags = 'u') {
    return (...args) => new RegExp(escapeStringRegExp(evalTemplate(...args))
        , flags)
}

function evalTemplate(strings, ...values) {
    let i = 0
    return strings.reduce((str, string) => `${str}${string}${
        i < values.length ? values[i++] : ''}`, '')
}

console.log(str2reg()`example.com`)
// => /example\.com/u

Yup, there's the convert_tz function.

Query for just a single known column:

session.query(MyTable.col1).count()

Here is a slight variation on answer offered by jfriend00:

$.fn.hasAnyClass = function() {
    var classes = arguments[0].split(" ");
    for (var i = 0; i < classes.length; i++) {
        if (this.hasClass(classes[i])) {
            return true;
        }
    }
    return false;
}

Allows use of same syntax as .addClass() and .removeClass(). e.g., .hasAnyClass('m320 m768') Needs bulletproofing, of course, as it assumes at least one argument.

On a mac you have to set keybinding yourself. Simply go to

Sublime --> Preference --> Key Binding - User  

and input the following:

{ "keys": ["shift+command+m"], "command": "goto_definition" }

This will enable keybinding of Shift + Command + M to enable goto definition. You can set the keybinding to anything you would like of course.

We can use case statement Like this

select Name,EmailId,gender=case 
when gender='M' then 'F'
when gender='F' then 'M'
end
 from [dbo].[Employees]

WE can also it as follow.

select Name,EmailId,case gender
when 'M' then 'F'
when 'F' then 'M'
end
 from [dbo].[Employees]

This is a solution if the date is a datetime object.

import datetime
def dow(date):
    days=["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"]
    dayNumber=date.weekday()
    print days[dayNumber]

for latest Jquery. Simply:

<script src="https://code.jquery.com/jquery-latest.min.js"></script>

You might be better off if you just don't use nested classes. If you must nest, try this:

x = 1
class OuterClass:
    outer_var = x
    class InnerClass:
        inner_var = x

Or declare both classes before nesting them:

class OuterClass:
    outer_var = 1

class InnerClass:
    inner_var = OuterClass.outer_var

OuterClass.InnerClass = InnerClass

(After this you can del InnerClass if you need to.)

Works for me in

url: http://localhost:8080/#/?access_token=111

function get(name){
  const parts = window.location.href.split('?');
  if (parts.length > 1) {
    name = encodeURIComponent(name);
    const params = parts[1].split('&');
    const found = params.filter(el => (el.split('=')[0] === name) && el);
    if (found.length) return decodeURIComponent(found[0].split('=')[1]);
  }
}

_ has 3 main conventional uses in Python:

1. To hold the result of the last executed expression(/statement) in an interactive interpreter session (see docs). This precedent was set by the standard CPython interpreter, and other interpreters have followed suit

2. For translation lookup in i18n (see the gettext documentation for example), as in code like

   raise forms.ValidationError(_("Please enter a correct username"))
   

3. As a general purpose "throwaway" variable name:

   1. To indicate that part of a function result is being deliberately ignored (Conceptually, it is being discarded.), as in code like:

      label, has_label, _ = text.partition(':')
      

   2. As part of a function definition (using either def or lambda), where the signature is fixed (e.g. by a callback or parent class API), but this particular function implementation doesn't need all of the parameters, as in code like:

      def callback(_):
          return True
      

      [For a long time this answer didn't list this use case, but it came up often enough, as noted here, to be worth listing explicitly.]

   This use case can conflict with the translation lookup use case, so it is necessary to avoid using _ as a throwaway variable in any code block that also uses it for i18n translation (many folks prefer a double-underscore, __, as their throwaway variable for exactly this reason).

   Linters often recognize this use case. For example year, month, day = date() will raise a lint warning if day is not used later in the code. The fix, if day is truly not needed, is to write year, month, _ = date(). Same with lambda functions, lambda arg: 1.0 creates a function requiring one argument but not using it, which will be caught by lint. The fix is to write lambda _: 1.0. An unused variable is often hiding a bug/typo (e.g. set day but use dya in the next line).

Here is a PHP solution ready for use with a n:m (many-to-many relationship) table :

// get data
$table_1 = get_table_1_rows();
$table_2_fk_id = 123;

// prepare first part of the query (before values)
$query = "INSERT INTO `table` (
   `table_1_fk_id`,
   `table_2_fk_id`,
   `insert_date`
) VALUES ";

//loop the table 1 to get all foreign keys and put it in array
foreach($table_1 as $row) {
    $query_values[] = "(".$row["table_1_pk_id"].", $table_2_fk_id, NOW())";
}

// Implode the query values array with a coma and execute the query.
$db->query($query . implode(',',$query_values));

This is copied from above, but condensed slightly and re-written in semantic terms. Note: #Container has display: flex; and flex-direction: column;, while the columns have flex: 3; and flex: 2; (where "One value, unitless number" determines the flex-grow property) per MDN flex docs.

#Container {_x000D_

In my tray app, I needed to clean Excel and Word Interops. So This simple method kills processes generically.

This uses a general exception handler, but could be easily split for multiple exceptions like stated in other answers. I may do this if my logging produces alot of false positives (ie can't kill already killed). But so far so guid (work joke).

/// <summary>
/// Kills Processes By Name
/// </summary>
/// <param name="names">List of Process Names</param>
private void killProcesses(List<string> names)
{
    var processes = new List<Process>();
    foreach (var name in names)
        processes.AddRange(Process.GetProcessesByName(name).ToList());
    foreach (Process p in processes)
    {
        try
        {
            p.Kill();
            p.WaitForExit();
        }
        catch (Exception ex)
        {
            // Logging
            RunProcess.insertFeedback("Clean Processes Failed", ex);
        }
    }
}

This is how i called it then:

killProcesses((new List<string>() { "winword", "excel" }));

package com.android.jigsawtest;

}

Yeah, the best way is to convert the object notation to a flat key-value string representation, as mentioned in this comment: https://stackoverflow.com/a/39357531/2529199

I wanted to highlight an alternative method using this NPM library: https://www.npmjs.com/package/dot-object which lets you manipulate different objects using dot notation.

I used this pattern to programatically create a nested object property when accepting the key-value as a function variable, as follows:

const dot = require('dot-object');

function(docid, varname, varvalue){
  let doc = dot.dot({
      [varname]: varvalue 
  });

  Mongo.update({_id:docid},{$set:doc});
}

This pattern lets me use nested as well as single-level properties interchangeably, and insert them cleanly into Mongo.

If you need to play around with JS Objects beyond just Mongo, especially on the client-side but have consistency when working with Mongo, this library gives you more options than the earlier mentioned mongo-dot-notation NPM module.

P.S I originally wanted to just mention this as a comment but apparently my S/O rep isn't high enough to post a comment. So, not trying to muscle in on SzybkiSasza's comment, just wanted to highlight providing an alternative module.

Just add background-attachment to your code

body {
    background-position: center;
    background-image: url(../images/images5.jpg);
    background-attachment: fixed;
}

That query is failing and returning false.

Put this after mysqli_query() to see what's going on.

if (!$check1_res) {
    printf("Error: %s\n", mysqli_error($con));
    exit();
}

For more information:

http://www.php.net/manual/en/mysqli.error.php

If you by any means searched this topic because of the post page (index page alternative when using static front page), then the right answer is this:

if (get_option('show_on_front') == 'page') {
    $page_id = get_option('page_for_posts');
    echo get_the_title($page_id);
}

I'll try to answer several key points: this is from long Hibernate/ persistence experience including several major applications.

Entity Class: implement Serializable?

Keys needs to implement Serializable. Stuff that's going to go in the HttpSession, or be sent over the wire by RPC/Java EE, needs to implement Serializable. Other stuff: not so much. Spend your time on what's important.

Constructors: create a constructor with all required fields of the entity?

Constructor(s) for application logic, should have only a few critical "foreign key" or "type/kind" fields which will always be known when creating the entity. The rest should be set by calling the setter methods -- that's what they're for.

Avoid putting too many fields into constructors. Constructors should be convenient, and give basic sanity to the object. Name, Type and/or Parents are all typically useful.

OTOH if application rules (today) require a Customer to have an Address, leave that to a setter. That is an example of a "weak rule". Maybe next week, you want to create a Customer object before going to the Enter Details screen? Don't trip yourself up, leave possibility for unknown, incomplete or "partially entered" data.

Constructors: also, package private default constructor?

Yes, but use 'protected' rather than package private. Subclassing stuff is a real pain when the necessary internals are not visible.

Fields/Properties

Use 'property' field access for Hibernate, and from outside the instance. Within the instance, use the fields directly. Reason: allows standard reflection, the simplest & most basic method for Hibernate, to work.

As for fields 'immutable' to the application -- Hibernate still needs to be able to load these. You could try making these methods 'private', and/or put an annotation on them, to prevent application code making unwanted access.

Note: when writing an equals() function, use getters for values on the 'other' instance! Otherwise, you'll hit uninitialized/ empty fields on proxy instances.

Protected is better for (Hibernate) performance?

Unlikely.

Equals/HashCode?

This is relevant to working with entities, before they've been saved -- which is a thorny issue. Hashing/comparing on immutable values? In most business applications, there aren't any.

A customer can change address, change the name of their business, etc etc -- not common, but it happens. Corrections also need to be possible to make, when the data was not entered correctly.

The few things that are normally kept immutable, are Parenting and perhaps Type/Kind -- normally the user recreates the record, rather than changing these. But these do not uniquely identify the entity!

So, long and short, the claimed "immutable" data isn't really. Primary Key/ ID fields are generated for the precise purpose, of providing such guaranteed stability & immutability.

You need to plan & consider your need for comparison & hashing & request-processing work phases when A) working with "changed/ bound data" from the UI if you compare/hash on "infrequently changed fields", or B) working with "unsaved data", if you compare/hash on ID.

Equals/HashCode -- if a unique Business Key is not available, use a non-transient UUID which is created when the entity is initialized

Yes, this is a good strategy when required. Be aware that UUIDs are not free, performance-wise though -- and clustering complicates things.

Equals/HashCode -- never refer to related entities

"If related entity (like a parent entity) needs to be part of the Business Key then add a non insertable, non updatable field to store the parent id (with the same name as the ManytoOne JoinColumn) and use this id in the equality check"

Sounds like good advice.

Hope this helps!

I went through all the examples and answers and in a way or another they didn't address my need. So I will list her a scenario that I need more help and I hope this can explain the idea more.

Initial Problem

I need to develop a tool which is getting a file to process it and it needs some optional configuration file to be used to configure the tool.

so what I need is something like the following

mytool.py file.text -config config-file.json

The solution

Here is the solution code

import argparse

def main():
    parser = argparse.ArgumentParser(description='This example for a tool to process a file and configure the tool using a config file.')
    parser.add_argument('filename', help="Input file either text, image or video")
    # parser.add_argument('config_file', help="a JSON file to load the initial configuration ")
    # parser.add_argument('-c', '--config_file', help="a JSON file to load the initial configuration ", default='configFile.json', required=False)
    parser.add_argument('-c', '--config', default='configFile.json', dest='config_file', help="a JSON file to load the initial configuration " )
    parser.add_argument('-d', '--debug', action="store_true", help="Enable the debug mode for logging debug statements." )

    args = parser.parse_args()
    
    filename = args.filename
    configfile = args.config_file

    print("The file to be processed is", filename)
    print("The config file is", configfile)

    if args.debug:
        print("Debug mode enabled")
    else:
        print("Debug mode disabled")

    print("and all arguments are: ", args)

if __name__ == '__main__':
    main()

I will show the solution in multiple enhancements to show the idea

First Round: List the arguments

List all input as mandatory inputs so second argument will be

parser.add_argument('config_file', help="a JSON file to load the initial configuration ")

When we get the help command for this tool we find the following outcome

(base) > python .\argparser_example.py -h
usage: argparser_example.py [-h] filename config_file

This example for a tool to process a file and configure the tool using a config file.

positional arguments:
  filename     Input file either text, image or video
  config_file  a JSON file to load the initial configuration

optional arguments:
  -h, --help   show this help message and exit

and when I execute it as the following

(base) > python .\argparser_example.py filename.txt configfile.json

the outcome will be

The file to be processed is filename.txt
The config file is configfile.json
and all arguments are:  Namespace(config_file='configfile.json', filename='filename.txt')

But the config file should be optional, I removed it from the arguments

(base) > python .\argparser_example.py filename.txt

The outcome will be is:

usage: argparser_example.py [-h] filename config_file
argparser_example.py: error: the following arguments are required: c

Which means we have a problem in the tool

Second Round : Make it optimal

So to make it optional I modified the program as follows

    parser.add_argument('-c', '--config', help="a JSON file to load the initial configuration ", default='configFile.json', required=False)

The help outcome should be

usage: argparser_example.py [-h] [-c CONFIG] filename

This example for a tool to process a file and configure the tool using a config file.

positional arguments:
  filename              Input file either text, image or video

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        a JSON file to load the initial configuration

so when I execute the program

(base) > python .\argparser_example.py filename.txt

the outcome will be

The file to be processed is filename.txt
The config file is configFile.json
and all arguments are:  Namespace(config_file='configFile.json', filename='filename.txt')

with arguments like

(base) > python .\argparser_example.py filename.txt --config_file anotherConfig.json

The outcome will be

The file to be processed is filename.txt
The config file is anotherConfig.json
and all arguments are:  Namespace(config_file='anotherConfig.json', filename='filename.txt')

Round 3: Enhancements

to change the flag name from --config_file to --config while we keep the variable name as is we modify the code to include dest='config_file' as the following:

parser.add_argument('-c', '--config', help="a JSON file to load the initial configuration ", default='configFile.json', dest='config_file')

and the command will be

(base) > python .\argparser_example.py filename.txt --config anotherConfig.json

To add the support for having a debug mode flag, we need to add a flag in the arguments to support a boolean debug flag. To implement it i added the following:

    parser.add_argument('-d', '--debug', action="store_true", help="Enable the debug mode for logging debug statements." )

the tool command will be:

(carnd-term1-38) > python .\argparser_example.py image.jpg -c imageConfig,json --debug

the outcome will be

The file to be processed is image.jpg
The config file is imageConfig,json
Debug mode enabled
and all arguments are:  Namespace(config_file='imageConfig,json', debug=True, filename='image.jpg')

I seem to be having success doing

org.jboss.logmanager.Logger logger = org.jboss.logmanager.Logger.getLogger("");
logger.setLevel(java.util.logging.Level.ALL);

Then to get detailed logging from netty, the following has done it

org.slf4j.impl.SimpleLogger.setLevel(org.slf4j.impl.SimpleLogger.TRACE);

CTE and only CTE :-)

just throw out extra stuff. Here is almost complete and verbose form for all cases of life. And you can use any concise form.

INSERT INTO reports r
  (r.id, r.name, r.key, r.param)

--

  -- Invoke this script from "WITH" to the end (";")
  -- to debug and see prepared values.
  WITH

  -- Some new data to add.
  newData AS(
          SELECT 'Name 1' name, 'key_new_1' key FROM DUAL
    UNION SELECT 'Name 2' NAME, 'key_new_2' key FROM DUAL
    UNION SELECT 'Name 3' NAME, 'key_new_3' key FROM DUAL
    ),
  -- Any single row for copying with each new row from "newData",
  -- if you will of course.
  copyData AS(
      SELECT r.*
      FROM reports r
      WHERE r.key = 'key_existing'
        -- ! Prevent more than one row to return.
        AND FALSE -- do something here for than!
    ),
  -- Last used ID from the "reports" table (it depends on your case).
  -- (not going to work with concurrent transactions)
  maxId AS (SELECT MAX(id) AS id FROM reports),

--

  -- Some construction of all data for insertion.
  SELECT maxId.id + ROWNUM, newData.name, newData.key, copyData.param
  FROM copyData
    -- matrix multiplication :)
    -- (or a recursion if you're imperative coder)
    CROSS JOIN newData
    CROSS JOIN maxId

--

  -- Let's prevent re-insertion.
  WHERE NOT EXISTS (
      SELECT 1 FROM reports rs
      WHERE rs.name IN(
        SELECT name FROM newData
      ));

I call it "IF NOT EXISTS" on steroids. So, this helps me and I mostly do so.

YES, You can do this on bellow ways:

1. By CrudRepository (Projection)

Spring Data Repositories usually return the domain model when using query methods. However, sometimes, you may need to alter the view of that model for various reasons.

Suppose your entity is like this :

    import javax.persistence.*;
    import java.math.BigDecimal;

    @Entity
    @Table(name = "USER_INFO_TEST")
    public class UserInfoTest {
        private int id;
        private String name;
        private String rollNo;

        public UserInfoTest() {
        }

        public UserInfoTest(int id, String name) {
        this.id = id;
        this.name = name;
        }

        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        @Column(name = "ID", nullable = false, precision = 0)
        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        @Basic
        @Column(name = "name", nullable = true)
        public String getName() {
            return name;
        }

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

        @Basic
        @Column(name = "roll_no", nullable = true)
        public String getRollNo() {
            return rollNo;
        }

        public void setRollNo(String rollNo) {
            this.rollNo = rollNo;
        }
    }

Now your Projection class is like bellow. It can those fields that you needed.

public interface IUserProjection {
     int getId();
     String getName();
     String getRollNo();
}

And Your Data Access Object(Dao) is like bellow :

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;

import java.util.ArrayList;

public interface UserInfoTestDao extends CrudRepository<UserInfoTest,Integer> {
    @Query(value = "select id,name,roll_no from USER_INFO_TEST where rollNo = ?1", nativeQuery = true)
    ArrayList<IUserProjection> findUserUsingRollNo(String rollNo);
}

Now ArrayList<IUserProjection> findUserUsingRollNo(String rollNo) will give you the list of user.

2. Using EntityManager

Suppose your query is "select id,name from users where roll_no = 1001".

Here query will return a object with id and name column. Your Response class is like bellow:

Your Response class is like:

public class UserObject{
        int id;
        String name;
        String rollNo;

        public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

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

        public String getRollNo() {
            return rollNo;
        }

        public void setRollNo(String rollNo) {
            this.rollNo = rollNo;
        }
    }

here UserObject constructor will get a Object Array and set data with object.

public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

Your query executing function is like bellow :

public UserObject getUserByRoll(EntityManager entityManager,String rollNo) {

        String queryStr = "select id,name from users where roll_no = ?1";
        try {
            Query query = entityManager.createNativeQuery(queryStr);
            query.setParameter(1, rollNo);

            return new UserObject((Object[]) query.getSingleResult());
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

Here you have to import bellow packages:

import javax.persistence.Query;
import javax.persistence.EntityManager;

Now your main class, you have to call this function. First get EntityManager and call this getUserByRoll(EntityManager entityManager,String rollNo) function. Calling procedure is given bellow:

Here is the Imports

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

get EntityManager from this way:

@PersistenceContext
private EntityManager entityManager;

UserObject userObject = getUserByRoll(entityManager,"1001");

Now you have data in this userObject.

Note:

query.getSingleResult() return a object array. You have to maintain the column position and data type with query column position.

select id,name from users where roll_no = 1001 

query return a array and it's [0] --> id and [1] -> name.

Thanks :)

The ID is only guaranteed to be generated at flush time. Persisting an entity only makes it "attached" to the persistence context. So, either flush the entity manager explicitely:

em.persist(abc);
em.flush();
return abc.getId();

or return the entity itself rather than its ID. When the transaction ends, the flush will happen, and users of the entity outside of the transaction will thus see the generated ID in the entity.

@Override
public ABC addNewABC(ABC abc) {
    abcDao.insertABC(abc);
    return abc;
}

I have created Delayed component using Hooks and TypeScript

import React, { useState, useEffect } from 'react';

type Props = {
  children: React.ReactNode;
  waitBeforeShow?: number;
};

const Delayed = ({ children, waitBeforeShow = 500 }: Props) => {
  const [isShown, setIsShown] = useState(false);

  useEffect(() => {
    setTimeout(() => {
      setIsShown(true);
    }, waitBeforeShow);
  }, [waitBeforeShow]);

  return isShown ? children : null;
};

export default Delayed;

Just wrap another component into Delayed

export function LoadingScreen = () => {
  return (
    <Delayed>
      <div />
    </Delayed>
  );
};

Input: 192.168.0.1/25

The mask is this part: /25

To find the network address do the following:

• Subtract the mask from the ip length (32 - mask) = 32 - 25 = 7 and take those bits from the right

• In the given ip address I.e: 192.168.0.1 in binary is: 11111111 11111111 00000000 00000001 Now, taking 7 bits from right '0' 1111111 11111111 00000000 00000000 Which in decimal is: 192.168.0.0 (this is the network address)

To find first valid/usable ip address add +1 to network address I.e: 192.168.0.1

To find the last/broadcast address the procedure is same as that of finding network address but here you have to make (32-mask) bits from right to '1'

I.e: 11111111 11111111 00000000 01111111 Which in decimal is 192.168.0.127

To find the last valid/usable ip address subtract 1 from the broadcast address I.e: 192.168.0.126

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

First case:

A normal product lookup would look like this

http://our.api.com/product/1

So Im thinking that best practice would be for you to do this

http://our.api.com/Product/101404,7267261

Second Case

Search with querystring parameters - fine like this. I would be tempted to combine terms with AND and OR instead of using [].

PS This can be subjective, so do what you feel comfortable with.

The reason for putting the data in the url is so the link can pasted on a site/ shared between users. If this isnt an issue, by all means use a JSON/ POST instead.

EDIT: On reflection I think this approach suits an entity with a compound key, but not a query for multiple entities.

You can also debug tomcat using the community edition (Unlike what is said above).

Start tomcat in debug mode, for example like this: .\catalina.bat jpda run

In intellij: Run > Edit Configurations > +

Select "Remote" Name the connection: "somename" Set "Port:" 8000 (default 5005)

Select Run > Debug "somename"

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray();
try {
    for(int i = 0; i < 3; i++) {
        // 1st object
        JSONObject list1 = new JSONObject();
        list1.put("val1",i+1);
        list1.put("val2",i+2);
        list1.put("val3",i+3);
        obj.put(list1);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}             
Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

use document.activeElement.blur();

example at http://jsfiddle.net/vGGdV/5/ that shows the currently focused element as well.

Keep a note though that calling blur() on the body element in IE will make the IE lose focus

Programmatic options for controlling services:

• Native code can used, "Starting a Service". Maximum control with minimum dependencies but the most work.
• WMI: Win32_Service has a StartService method. This is good for cases where you need to be able to perform other processing (e.g. to select which service).
• PowerShell: execute Start-Service via RunspaceInvoke or by creating your own Runspace and using its CreatePipeline method to execute. This is good for cases where you need to be able to perform other processing (e.g. to select which service) with a much easier coding model than WMI, but depends on PSH being installed.
• A .NET application can use ServiceController

Is not as old as other questions, but I just struggled with this in an Ionic-Laravel app, and nothing works from here (and other posts), so I installed https://github.com/barryvdh/laravel-cors complement in Laravel and started and it works pretty well.

Creation time isn't stored.

What are stored are three timestamps (generally, they can be turned off on certain filesystems or by certain filesystem options):

• Last access time
• Last modification time
• Last change time

a "Change" to the file is counted as permission changes, rename etc. While the modification is contents only.

The strcomp function may be appropriate here (returns 0 when strings are identical):

 SELECT * from table WHERE Strcmp(user, testername) <> 0;

I found 5 main ways to iterate over a Linked List in Java (including the Java 8 way):

1. For Loop
2. Enhanced For Loop
3. While Loop
4. Iterator
5. Collections’s stream() util (Java8)

For loop

LinkedList<String> linkedList = new LinkedList<>();
System.out.println("==> For Loop Example.");
for (int i = 0; i < linkedList.size(); i++) {
    System.out.println(linkedList.get(i));
}

Enhanced for loop

for (String temp : linkedList) {
    System.out.println(temp);
}

While loop

int i = 0;
while (i < linkedList.size()) {
    System.out.println(linkedList.get(i));
    i++;
}

Iterator

Iterator<String> iterator = linkedList.iterator();
while (iterator.hasNext()) {
    System.out.println(iterator.next()); 
}

collection stream() util (Java 8)

linkedList.forEach((temp) -> {
    System.out.println(temp);
});

One thing should be pointed out is that the running time of For Loop or While Loop is O(n square) because get(i) operation takes O(n) time(see this for details). The other 3 ways take linear time and performs better.

This might have been asked before. See Can I add jars to maven 2 build classpath without installing them?

In a nutshell: include your jar as dependency with system scope. This requires specifying the absolute path to the jar.

    arr1=list(map(int,input().split()))

the for loop shall run 'n' number of times . the second 'n' is the length of the array. the last statement maps the integers to a list and takes input in space separated form . you can also return the array at the end of for loop.

strong is the default. An object remains “alive” as long as there is a strong pointer to it.

weak specifies a reference that does not keep the referenced object alive. A weak reference is set to nil when there are no strong references to the object.

Install the one you use most (3.3 in my case) over the top of the other. That'll force IDLE to use the one you want.

Alternatively (from the python3.3 README):

Installing multiple versions

On Unix and Mac systems if you intend to install multiple versions of Python using the same installation prefix (--prefix argument to the configure script) you must take care that your primary python executable is not overwritten by the installation of a different version. All files and directories installed using "make altinstall" contain the major and minor version and can thus live side-by-side. "make install" also creates ${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y. If you intend to install multiple versions using the same prefix you must decide which version (if any) is your "primary" version. Install that version using "make install". Install all other versions using "make altinstall".

For example, if you want to install Python 2.6, 2.7 and 3.3 with 2.7 being the primary version, you would execute "make install" in your 2.7 build directory and "make altinstall" in the others.

      if($query)
       {
        // try to export to excel the whole data ---
        //initialize php excel first  
        ob_end_clean();
        //--- create php excel object ---
        $objPHPExcel = new PHPExcel();
        //define cachemethod
        ini_set('memory_limit', '3500M');
        $cacheMethod   = PHPExcel_CachedObjectStorageFactory::cache_to_phpTemp;
        $cacheSettings = array('memoryCacheSize' => '800MB');
        //set php excel settings
        PHPExcel_Settings::setCacheStorageMethod(
                $cacheMethod,$cacheSettings
              );


        $objPHPExcel->getProperties()->setTitle("export")->setDescription("none");

        $objPHPExcel->setActiveSheetIndex(0);

        // Field names in the first row
        $fields = $query->list_fields();
        $col = 0;
        foreach ($fields as $field)
        {
            $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
            $col++;
        }

        // Fetching the table data
        $row = 2;
        foreach($query->result() as $data)
        {
            $col = 0;
            foreach ($fields as $field)
            {
                $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);
                $col++;
            }

            $row++;
        }

        $objPHPExcel->setActiveSheetIndex(0);
        //redirect to cleint browser
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename=Provinces.xlsx');
        header('Cache-Control: max-age=0');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
        $objWriter->save('php://output');
     }

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

put at the end it will reopen your console

The <section> tag defines sections in a document, such as chapters, headers, footers, or any other sections of the document.

whereas:

The <div> tag defines a division or a section in an HTML document.

The <div> tag is used to group block-elements to format them with CSS.

I have found the answer... click on the installer and check the box "Add python to environment variables" DO NOT uninstall the old one rather click on modify....Click on link for picture...

its too simple, you can just type "cache:" before the URL of the page. for example if you want to check the last webcache of this page simply type on URL bar cache:http://stackoverflow.com/questions/4560400/how-can-i-get-the-google-cache-age-of-any-url-or-web-page

this will show you the last webcache of the page.see here:

But remember, the caching of a webpage will only show if the page is already indexed on search engine(Google). for this you need to check the meta robot tag of that page.

DECLARE @CodeNameString varchar(max)
SET @CodeNameString=''

SELECT @CodeNameString=@CodeNameString+CodeName FROM AccountCodes ORDER BY Sort
SELECT @CodeNameString

var objectA = {}

is a lot quicker and, in my experience, more commonly used, so it's probably best to adopt the 'standard' and save some typing.

All you need is to force disable C.M. in IE - Just paste This code (in IE9 and under c.m. will be disabled):

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7; IE=EDGE" />

you must use datepart()

like 


datepart(hour , getdate())

The other answers overcomplicate it for me.

let animals = {
  a: 'dog',
  b: 'cat',
  c: 'bird'
}

let lastKey = Object.keys(animals).pop()
let lastValue = animals[Object.keys(animals).pop()]

Here is an alternative method using ls:

(ls x.txt && echo yes) || echo no

If you want to hide any output from ls so you only see yes or no, redirect stdout and stderr to /dev/null:

(ls x.txt >> /dev/null 2>&1 && echo yes) || echo no

You can size it as follows.

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.

It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.

Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.

My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

This function will transform an application to a daemon:

import sys
import os

def daemonize():
    try:
        pid = os.fork()
        if pid > 0:
            # exit first parent
            sys.exit(0)
    except OSError as err:
        sys.stderr.write('_Fork #1 failed: {0}\n'.format(err))
        sys.exit(1)
    # decouple from parent environment
    os.chdir('/')
    os.setsid()
    os.umask(0)
    # do second fork
    try:
        pid = os.fork()
        if pid > 0:
            # exit from second parent
            sys.exit(0)
    except OSError as err:

    se = open(os.devnull, 'w')
    os.dup2(si.fileno(), sys.stdin.fileno())
    os.dup2(so.fileno(), sys.stdout.fileno())
    os.dup2(se.fileno(), sys.stderr.fileno())

System.Data.SQLite has a dependency on System.Data.SQLite.interop make sure both packages are the same version and are both x86.

This is an old question, but I tried all the above. I was working on a strictly x86 project, so there was not two folders /x86, /x64. But for some reason, the System.Data.SQLite was a different version to System.Data.SQLite.interop, once I pulled down matching dlls the problem was fixed.

Make a bypass API in server.js. This works for me.

app.post('/by-pass-api',function(req, response){
  const url = req.body.url;
  console.log("calling url", url);
  request.get(
    url,
    (error, res, body) => {
      if (error) {
        console.error(error)
        return response.status(200).json({'content': "error"}) 
}
        return response.status(200).json(JSON.parse(body))
        },
      )
    })

And call it using axios or fetch like this:

const options = {
     method: 'POST',
     headers: {'content-type': 'application/json'},
     url:`http://localhost:3000/by-pass-api`, // your environment 
     data: { url },  // your https request here
    };

Don't forget to include

import Image

In order to show it use this :

Image.open('pathToFile').show()

It depends what you're going for. I believe the closest thing JS has to print is:

document.write( produceMessage() );

However, it may be more prudent to place the value inside a span or a div of your choosing like:

document.getElementById("mySpanId").innerHTML = produceMessage();

Daniel's answer was good except I had to change this code...

    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

to this code...

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
    SchemeRegistry registry = ccm.getShemeRegistry()
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

to get it to work.

Simply use _.uniqBy(). It creates duplicate-free version of an array.

This is a new way and available from 4.0.0 version.

_.uniqBy(data, 'id');

or

_.uniqBy(data, obj => obj.id);

See TRY...CATCH (Transact-SQL)

• First line : array created.
• Third line loop started from j = 1 to j = 28123
• Fourth line you give the variable x value (0) each time the loop is accessed.
• Fifth line you put the value of j in the index 0.
• Sixth line you do increment to the value x by 1.(but it will be reset to 0 at line 4)

Use a font-awesome icon as the default icon of your navbar.

<span class="navbar-toggler-icon">   
    <i class="fas fa-bars" style="color:#fff; font-size:28px;"></i>
</span>

Or try this on old font-awesome versions:

<span class="navbar-toggler-icon">   
    <i class="fa fa-navicon" style="color:#fff; font-size:28px;"></i>
</span>

Here's the real solution (with other cool CSS3 stuff):

#fixed-square {
position: fixed;
top: 0;
right: 0;
z-index: 9500;
cursor: pointer;
width: 24px;
padding: 18px 18px 14px;
opacity: 0.618;
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
-webkit-transition: all 0.145s ease-out;
-moz-transition: all 0.145s ease-out;
-ms-transition: all 0.145s ease-out;
transition: all 0.145s ease-out;
}

Note the top:0 and right:0. That's what did it for me.

ALTER TABLE TABLE_NAME ADD INDEX (COLUMN_NAME);

You can use the Source property of the image. Try this code...

ImageSource imageSource = new BitmapImage(new Uri("C:\\FileName.gif"));

image1.Source = imageSource;

This is a side note, but in idiomatic Python, you will often see things like:

if x is None:
    # Some clauses

This is safe, because there is guaranteed to be one instance of the Null Object (i.e., None).

Try this it worked for me.

I know it's kinda late answer but I just lost about half an hour debugging cause of this, It might save someone some time.

BE MINDFUL, If you use angular.equals() on objects that have property obj.$something (property name starts with $) those properties will get ignored in comparison.

Example:

var obj1 = {
  $key0: "A",
  key1: "value1",
  key2: "value2",
  key3: {a: "aa", b: "bb"}
}

var obj2 = {
  $key0: "B"
  key2: "value2",
  key1: "value1",
  key3: {a: "aa", b: "bb"}
}

angular.equals(obj1, obj2) //<--- would return TRUE (despite it's not true)

HTTP authorization does not differ between GET and POST requests, so I would first assume that something else is wrong. Instead of setting the Authorization header directly, I would suggest using the java.net.Authorization class, but I am not sure if it solves your problem. Perhaps your server is somehow configured to require a different authorization scheme than "basic" for post requests?

Since the other answers explained how to do it without actually explaining why it works:

When the switch executes, it finds the first matching case statement and then executes each line of code after the switch until it hits either a break statement or the end of the switch (or a return statement to leave the entire containing function). When you deliberately omit the break so that code under the next case gets executed too that's called a fall-through. So for the OP's requirement:

switch (pageid) {
   case "listing-page":
   case "home-page":
      alert("hello");
      break;

   case "details-page":
      alert("goodbye");
      break;
} 

Forgetting to include break statements is a fairly common coding mistake and is the first thing you should look for if your switch isn't working the way you expected. For that reason some people like to put a comment in to say "fall through" to make it clear when break statements have been omitted on purpose. I do that in the following example since it is a bit more complicated and shows how some cases can include code to execute before they fall-through:

switch (someVar) {
   case 1:
      someFunction();
      alert("It was 1");
      // fall through
   case 2:
      alert("The 2 case");
      // fall through
   case 3:
      // fall through
   case 4:
      // fall through
   case 5:
      alert("The 5 case");
      // fall through
   case 6:
      alert("The 6 case");
      break;

   case 7:
      alert("Something else");
      break;

   case 8:
      // fall through
   default:
      alert("The end");
      break;
}

You can also (optionally) include a default case, which will be executed if none of the other cases match - if you don't include a default and no cases match then nothing happens. You can (optionally) fall through to the default case.

So in my second example if someVar is 1 it would call someFunction() and then you would see four alerts as it falls through multiple cases some of which have alerts under them. Is someVar is 3, 4 or 5 you'd see two alerts. If someVar is 7 you'd see "Something else" and if it is 8 or any other value you'd see "The end".

If you want to keep your CustomView and its xib independent of File's Owner, then follow these steps

• Leave the File's Owner field empty.
• Click on actual view in xib file of your CustomView and set its Custom Class as CustomView (name of your custom view class)
• Add IBOutlet in .h file of your custom view.
• In .xib file of your custom view, click on view and go in Connection Inspector. Here you will all your IBOutlets which you define in .h file
• Connect them with their respective view.

in .m file of your CustomView class, override the init method as follow

-(CustomView *) init{
    CustomView *result = nil;
    NSArray* elements = [[NSBundle mainBundle] loadNibNamed: NSStringFromClass([self class]) owner:self options: nil];
    for (id anObject in elements)
    {
        if ([anObject isKindOfClass:[self class]])
        {
            result = anObject;
            break;
        }
    }
    return result;
}

Now when you want to load your CustomView, use the following line of code [[CustomView alloc] init];

Try looking at the java.awt.Robot class. It allows you to move the mouse programatically.

There's several ways to do it, depending on your intent.

thisSession.hasOwnProperty('merchant_id'); will tell you if thisSession has that key itself (i.e. not something it inherits from elsewhere)

"merchant_id" in thisSession will tell you if thisSession has the key at all, regardless of where it got it.

thisSession["merchant_id"] will return false if the key does not exist, or if its value evaluates to false for any reason (e.g. if it's a literal false or the integer 0 and so on).

You are using a table variable i.e. you should declare the table. This is not a temporary table.

You create a temp table like so:

CREATE TABLE #customer
(
     Name varchar(32) not null
)

You declare a table variable like so:

DECLARE @Customer TABLE
(
      Name varchar(32) not null
)

Notice that a temp table is declared using # and a table variable is declared using a @. Go read about the difference between table variables and temp tables.

UPDATE:

Based on your comment below you are actually trying to create tables in a stored procedure. For this you would need to use dynamic SQL. Basically dynamic SQL allows you to construct a SQL Statement in the form of a string and then execute it. This is the ONLY way you will be able to create a table in a stored procedure. I am going to show you how and then discuss why this is not generally a good idea.

Now for a simple example (I have not tested this code but it should give you a good indication of how to do it):

CREATE PROCEDURE sproc_BuildTable 
    @TableName NVARCHAR(128)
   ,@Column1Name NVARCHAR(32)
   ,@Column1DataType NVARCHAR(32)
   ,@Column1Nullable NVARCHAR(32)
AS

   DECLARE @SQLString NVARCHAR(MAX)
   SET @SQString = 'CREATE TABLE '+@TableName + '( '+@Column1Name+' '+@Column1DataType +' '+@Column1Nullable +') ON PRIMARY '

   EXEC (@SQLString)
   GO

This stored procedure can be executed like this:

sproc_BuildTable 'Customers','CustomerName','VARCHAR(32)','NOT NULL'

There are some major problems with this type of stored procedure.

Its going to be difficult to cater for complex tables. Imagine the following table structure:

CREATE TABLE [dbo].[Customers] (
    [CustomerID] [int] IDENTITY(1,1) NOT NULL,
    [CustomerName] [nvarchar](64) NOT NULL,
    [CustomerSUrname] [nvarchar](64) NOT NULL,
    [CustomerDateOfBirth] [datetime] NOT NULL,
    [CustomerApprovedDiscount] [decimal](3, 2) NOT NULL,
    [CustomerActive] [bit] NOT NULL,
    CONSTRAINT [PK_Customers] PRIMARY KEY CLUSTERED 
    (
        [CustomerID] ASC
    ) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,      ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Customers] ADD CONSTRAINT [DF_Customers_CustomerApprovedDiscount] DEFAULT ((0.00)) FOR [CustomerApprovedDiscount]
GO 

This table is a little more complex than the first example, but not a lot. The stored procedure will be much, much more complex to deal with. So while this approach might work for small tables it is quickly going to be unmanageable.

Creating tables require planning. When you create tables they should be placed strategically on different filegroups. This is to ensure that you don't cause disk I/O contention. How will you address scalability if everything is created on the primary file group?

Could you clarify why you need tables to be created dynamically?

UPDATE 2:

Delayed update due to workload. I read your comment about needing to create a table for each shop and I think you should look at doing it like the example I am about to give you.

In this example I make the following assumptions:

1. It's an e-commerce site that has many shops
2. A shop can have many items (goods) to sell.
3. A particular item (good) can be sold at many shops
4. A shop will charge different prices for different items (goods)
5. All prices are in $ (USD)

Let say this e-commerce site sells gaming consoles (i.e. Wii, PS3, XBOX360).

Looking at my assumptions I see a classical many-to-many relationship. A shop can sell many items (goods) and items (goods) can be sold at many shops. Let's break this down into tables.

First I would need a shop table to store all the information about the shop.

A simple shop table might look like this:

CREATE TABLE [dbo].[Shop](
    [ShopID] [int] IDENTITY(1,1) NOT NULL,
    [ShopName] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_Shop] PRIMARY KEY CLUSTERED 
    (
      [ShopID] ASC
    ) WITH (
              PAD_INDEX  = OFF
              , STATISTICS_NORECOMPUTE  = OFF
              , IGNORE_DUP_KEY = OFF
              , ALLOW_ROW_LOCKS  = ON
              , ALLOW_PAGE_LOCKS  = ON
    ) ON [PRIMARY]
    ) ON [PRIMARY]

    GO

Let's insert three shops into the database to use during our example. The following code will insert three shops:

INSERT INTO Shop
SELECT 'American Games R US'
UNION
SELECT 'Europe Gaming Experience'
UNION
SELECT 'Asian Games Emporium'

If you execute a SELECT * FROM Shop you will probably see the following:

ShopID  ShopName
1           American Games R US
2           Asian Games Emporium
3           Europe Gaming Experience

Right, so now let's move onto the Items (goods) table. Since the items/goods are products of various companies I am going to call the table product. You can execute the following code to create a simple Product table.

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductDescription] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_Product] PRIMARY KEY CLUSTERED 
 (
     [ProductID] ASC
 )WITH (PAD_INDEX  = OFF
        , STATISTICS_NORECOMPUTE  = OFF
        , IGNORE_DUP_KEY = OFF
        ,     ALLOW_ROW_LOCKS  = ON
         , ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

GO

Let's populate the products table with some products. Execute the following code to insert some products:

INSERT INTO Product
SELECT 'Wii'
UNION 
SELECT 'PS3'
UNION 
SELECT 'XBOX360'

If you execute SELECT * FROM Product you will probably see the following:

ProductID   ProductDescription
1           PS3
2           Wii
3           XBOX360

OK, at this point you have both product and shop information. So how do you bring them together? Well we know we can identify the shop by its ShopID primary key column and we know we can identify a product by its ProductID primary key column. Also, since each shop has a different price for each product we need to store the price the shop charges for the product.

So we have a table that maps the Shop to the product. We will call this table ShopProduct. A simple version of this table might look like this:

CREATE TABLE [dbo].[ShopProduct](
[ShopID] [int] NOT NULL,
[ProductID] [int] NOT NULL,
[Price] [money] NOT NULL,
CONSTRAINT [PK_ShopProduct] PRIMARY KEY CLUSTERED 
 (

So let's assume the American Games R Us shop only sells American consoles, the Europe Gaming Experience sells all consoles and the Asian Games Emporium sells only Asian consoles. We would need to map the primary keys from the shop and product tables into the ShopProduct table.

Here is how we are going to do the mapping. In my example the American Games R Us has a ShopID value of 1 (this is the primary key value) and I can see that the XBOX360 has a value of 3 and the shop has listed the XBOX360 for $159.99

By executing the following code you would complete the mapping:

INSERT INTO ShopProduct VALUES(1,3,159.99)

Now we want to add all product to the Europe Gaming Experience shop. In this example we know that the Europe Gaming Experience shop has a ShopID of 3 and since it sells all consoles we will need to insert the ProductID 1, 2 and 3 into the mapping table. Let's assume the prices for the consoles (products) at the Europe Gaming Experience shop are as follows: 1- The PS3 sells for $259.99 , 2- The Wii sells for $159.99 , 3- The XBOX360 sells for $199.99.

To get this mapping done you would need to execute the following code:

INSERT INTO ShopProduct VALUES(3,2,159.99) --This will insert the WII console into the mapping table for the Europe Gaming Experience Shop with a price of 159.99
INSERT INTO ShopProduct VALUES(3,1,259.99) --This will insert the PS3 console into the mapping table for the Europe Gaming Experience Shop with a price of 259.99
INSERT INTO ShopProduct VALUES(3,3,199.99) --This will insert the XBOX360 console into the mapping table for the Europe Gaming Experience Shop with a price of 199.99

At this point you have mapped two shops and their products into the mapping table. OK, so now how do I bring this all together to show a user browsing the website? Let's say you want to show all the product for the European Gaming Experience to a user on a web page – you would need to execute the following query:

SELECT      Shop.*
        , ShopProduct.*
        , Product.*
FROM         Shop 
INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
WHERE       Shop.ShopID=3

You will probably see the following results:

ShopID     ShopName                 ShopID  ProductID   Price   ProductID   ProductDescription
3          Europe Gaming Experience   3         1       259.99  1           PS3
3          Europe Gaming Experience   3         2       159.99  2           Wii
3          Europe Gaming Experience   3         3       199.99  3           XBOX360

Now for one last example, let's assume that your website has a feature which finds the cheapest price for a console. A user asks to find the cheapest prices for XBOX360.

You can execute the following query:

 SELECT     Shop.*
        , ShopProduct.*
        , Product.*
 FROM         Shop 
 INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
 INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
 WHERE      Product.ProductID =3  -- You can also use Product.ProductDescription = 'XBOX360'
 ORDER BY    Price ASC

This query will return a list of all shops which sells the XBOX360 with the cheapest shop first and so on.

You will notice that I have not added the Asian Games shop. As an exercise, add the Asian games shop to the mapping table with the following products: the Asian Games Emporium sells the Wii games console for $99.99 and the PS3 console for $159.99. If you work through this example you should now understand how to model a many-to-many relationship.

I hope this helps you in your travels with database design.

Latest revision based on comment from BinaryZebra's comment and tested here. The addition of command eval allows for the expression to be kept in the present execution environment while the expressions before are only held for the duration of the eval.

Use $IFS that has no spaces\tabs, just newlines/CR

$ IFS=$'\r\n' GLOBIGNORE='*' command eval  'XYZ=($(cat /etc/passwd))'
$ echo "${XYZ[5]}"
sync:x:5:0:sync:/sbin:/bin/sync

Also note that you may be setting the array just fine but reading it wrong - be sure to use both double-quotes "" and braces {} as in the example above

Edit:

Please note the many warnings about my answer in comments about possible glob expansion, specifically gniourf-gniourf's comments about my prior attempts to work around

With all those warnings in mind I'm still leaving this answer here (yes, bash 4 has been out for many years but I recall that some macs only 2/3 years old have pre-4 as default shell)

Other notes:

Can also follow drizzt's suggestion below and replace a forked subshell+cat with

$(</etc/passwd)

The other option I sometimes use is just set IFS into XIFS, then restore after. See also Sorpigal's answer which does not need to bother with this

Install nodemon:

sudo npm install -g nodemon

Run server:

sudo nodemon server.js

I did something like this once;

EditText usernameEditText = (EditText) findViewById(R.id.editUsername);
sUsername = usernameEditText.getText().toString();
if (sUsername.matches("")) {
    Toast.makeText(this, "You did not enter a username", Toast.LENGTH_SHORT).show();
    return;
}

It's actually fairly easy, just enter it as a latitude,longitude pair, ie 46.38S,115.36E (which is in the middle of the ocean). You'll want to convert it to decimal though (divide the minutes portion by 60 and add it to the degrees [I've done that with your example]).

I found a function called sleep function on the internet and don't know who made it. Here it is.

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

sleep(2000);

Your classes should look like this

[XmlRoot("StepList")]
public class StepList
{
    [XmlElement("Step")]
    public List<Step> Steps { get; set; }
}

public class Step
{
    [XmlElement("Name")]
    public string Name { get; set; }
    [XmlElement("Desc")]
    public string Desc { get; set; }
}

Here is my testcode.

string testData = @"<StepList>
                        <Step>
                            <Name>Name1</Name>
                            <Desc>Desc1</Desc>
                        </Step>
                        <Step>
                            <Name>Name2</Name>
                            <Desc>Desc2</Desc>
                        </Step>
                    </StepList>";

XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
    StepList result = (StepList) serializer.Deserialize(reader);
}

If you want to read a text file you should load the file into a FileStream and deserialize this.

using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open)) 
{
    StepList result = (StepList) serializer.Deserialize(fileStream);
}

UPDATE

Angular offers now the two scope methods $watchGroup (since 1.3) and $watchCollection. Those have been mentioned by @blazemonger and @kargold.

This should work independent of the types and values:

$scope.$watch('[age,name]', function () { ... }, true);

You have to set the third parameter to true in this case.

The string concatenation 'age + name' will fail in a case like this:

<button ng-init="age=42;name='foo'" ng-click="age=4;name='2foo'">click</button>

Before the user clicks the button the watched value would be 42foo (42 + foo) and after the click 42foo (4 + 2foo). So the watch function would not be called. So better use an array expression if you cannot ensure, that such a case will not appear.

PS:

As stated by @reblace in a comment, it is of course possible to access the values:

$scope.$watch('[age,name]', function (newValue, oldValue) {
    var newAge  = newValue[0];
    var newName = newValue[1];
    var oldAge  = oldValue[0];
    var oldName = oldValue[1];
}, true);

This should do it (bold as well);

label1.Font = new Font("Serif", 24,FontStyle.Bold);

I suggest using Render, as the ElementRef API doc suggests:

... take a look at Renderer which provides API that can safely be used even when direct access to native elements is not supported. Relying on direct DOM access creates tight coupling between your application and rendering layers which will make it impossible to separate the two and deploy your application into a web worker or Universal.

Always use the Renderer for it will make you code (or library you right) be able to work when using Universal or WebWorkers.

import { Directive, ElementRef, HostListener, Input, Renderer } from '@angular/core';

export class HighlightDirective {
    constructor(el: ElementRef, renderer: Renderer) {
        renderer.setElementProperty(el.nativeElement, 'innerHTML', 'some new value');
    }
}

It doesn't look like Render has a getElementProperty() method though, so I guess we still need to use NativeElement for that part. Or (better) pass the content in as an input property to the directive.

how can scrapy be used to scrape this dynamic data so that I can use it?

I wonder why no one has posted the solution using Scrapy only.

Check out the blog post from Scrapy team SCRAPING INFINITE SCROLLING PAGES . The example scraps http://spidyquotes.herokuapp.com/scroll website which uses infinite scrolling.

The idea is to use Developer Tools of your browser and notice the AJAX requests, then based on that information create the requests for Scrapy.

import json
import scrapy


class SpidyQuotesSpider(scrapy.Spider):
    name = 'spidyquotes'
    quotes_base_url = 'http://spidyquotes.herokuapp.com/api/quotes?page=%s'
    start_urls = [quotes_base_url % 1]
    download_delay = 1.5

    def parse(self, response):
        data = json.loads(response.body)
        for item in data.get('quotes', []):
            yield {
                'text': item.get('text'),
                'author': item.get('author', {}).get('name'),
                'tags': item.get('tags'),
            }
        if data['has_next']:
            next_page = data['page'] + 1
            yield scrapy.Request(self.quotes_base_url % next_page)

Use the "+" symbol to cast a string to a number.

window.location.hash = +page_number;

use kubeadm reset command. this will un-configure the kubernetes cluster.

After spending the day I realized it was a simple change in Project Settings

File -> Project Settings... -> Build System -> Legacy Build System.

In a project setting, you will see Build System named drop down and in that drop down select Legacy Build System

And as a context manager:

import signal

class GracefulInterruptHandler(object):

    def __init__(self, sig=signal.SIGINT):
        self.sig = sig

    def __enter__(self):

        self.interrupted = False
        self.released = False

        self.original_handler = signal.getsignal(self.sig)

        def handler(signum, frame):
            self.release()
            self.interrupted = True

        signal.signal(self.sig, handler)

        return self

    def __exit__(self, type, value, tb):
        self.release()

    def release(self):

        if self.released:
            return False

        signal.signal(self.sig, self.original_handler)

        self.released = True

        return True

To use:

with GracefulInterruptHandler() as h:
    for i in xrange(1000):
        print "..."
        time.sleep(1)
        if h.interrupted:
            print "interrupted!"
            time.sleep(2)
            break

Nested handlers:

with GracefulInterruptHandler() as h1:
    while True:
        print "(1)..."
        time.sleep(1)
        with GracefulInterruptHandler() as h2:
            while True:
                print "\t(2)..."
                time.sleep(1)
                if h2.interrupted:
                    print "\t(2) interrupted!"
                    time.sleep(2)
                    break
        if h1.interrupted:
            print "(1) interrupted!"
            time.sleep(2)
            break

Nothing could be simple than this. Use OkHttpLibrary

Create your json

JSONObject requestObject = new JSONObject();
requestObject.put("Email", email);
requestObject.put("Password", password);

and send it like this.

OkHttpClient client = new OkHttpClient();

RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
            .addHeader("Content-Type","application/json")
            .url(url)
            .post(requestObject.toString())
            .build();

okhttp3.Response response = client.newCall(request).execute();

if you want to do same thing Store Procedure then you need to apply below code.

select  (datediff(dd,'+CHAR(39)+ convert(varchar(10),@FromDate  ,101)+ 
 CHAR(39)+','+CHAR(39)+ convert(varchar(10),@ToDate  ,101) + CHAR(39) +')) 
 Daysdiff

where @fromdate and @todate is Parameter of the SP

you can use position:relative; inside #one div and position:absolute inside #two div. you can see it

You simply need to use semilogy instead of plot:

from pylab import *
import matplotlib.pyplot  as pyplot
a = [ pow(10,i) for i in range(10) ]
fig = pyplot.figure()
ax = fig.add_subplot(2,1,1)

line, = ax.semilogy(a, color='blue', lw=2)
show()

According to other answers I am adding the parallel stages scenario:

pipeline {
    agent any
    stages {
        stage('some parallel stage') {
            parallel {
                stage('parallel stage 1') {
                    when {
                      expression { ENV == "something" }
                    }
                    steps {
                        echo 'something'
                    }
                }
                stage('parallel stage 2') {
                    steps {
                        echo 'something'
                    }
                }
            }
        }
    }
}

You can use getChanges() on Eloquent model even after persisting.

A simpler way to get the selected value from a ComboBox control is:

Private Sub myComboBox_Change()
  msgbox "You selected: " + myComboBox.SelText
End Sub

I had the problem that onRestoreInstanceState restored all my custom views with the state of the last view. I solved it by adding these two methods to my custom view:

@Override
protected void dispatchSaveInstanceState(SparseArray<Parcelable> container) {
    dispatchFreezeSelfOnly(container);
}

@Override
protected void dispatchRestoreInstanceState(SparseArray<Parcelable> container) {
    dispatchThawSelfOnly(container);
}

Here is an example of using the loop:

echo off
cls

:begin

set /P M=Input text to encode md5, press ENTER to exit: 
if %M%==%M1% goto end

echo.|set /p ="%M%" | openssl md5

set M1=%M%
Goto begin

This is the simple batch i use when i need to encrypt any message into md5 hash on Windows(openssl required), and the program would loyally repeat itself except given Ctrl+C or empty input.

You could use module scope. Say you have a module called utils:

f_value = 'foo'

def f():
    return f_value

f_value is a module attribute that can be modified by any other module that imports it. As modules are singletons, any change to utils from one module will be accessible to all other modules that have it imported:

>> import utils
>> utils.f()
'foo'
>> utils.f_value = 'bar'
>> utils.f()
'bar'

Note that you can import the function by name:

>> import utils
>> from utils import f
>> utils.f_value = 'bar'
>> f()
'bar'

But not the attribute:

>> from utils import f, f_value
>> f_value = 'bar'
>> f()
'foo'

This is because you're labeling the object referenced by the module attribute as f_value in the local scope, but then rebinding it to the string bar, while the function f is still referring to the module attribute.

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

I recently answered a different question where I discussed why the box model is the way it is.

There are specific reasons for each part of the box model. Padding is meant to extend the background beyond its contents. If you need to shrink the background of the container, you should make the parent container the correct size and give the child element some negative margins. In this case the content is not being padded, it's overflowing.

Some solutions work well for me but numpy will deprecate some parameters. The solution that work better for me is to read the date as a pandas datetime and excract explicitly the year, month and day of a pandas object. The following code works for the most common situation.

def format_dates(dates):
    dt = pd.to_datetime(dates)
    try: return [datetime.date(x.year, x.month, x.day) for x in dt]    
    except TypeError: return datetime.date(dt.year, dt.month, dt.day)

IIS uses Integrated Authentication and by default IE has the ability to use your windows user account...but don't worry, so does Firefox but you'll have to make a quick configuration change.

1) Open up Firefox and type in about:config as the url

2) In the Filter Type in ntlm

3) Double click "network.automatic-ntlm-auth.trusted-uris" and type in localhost and hit enter

4) Write Thank You To Blogger

As Always, Hope this helped you out.

This was copied from link text

That should be what --link is for, at least for the hostname part.
With docker 1.10, and PR 19242, that would be:

docker network create --net-alias=[]: Add network-scoped alias for the container

(see last section below)

That is what Updating the /etc/hosts file details

In addition to the environment variables, Docker adds a host entry for the source container to the /etc/hosts file.

For instance, launch an LDAP server:

docker run -t  --name openldap -d -p 389:389 larrycai/openldap

And define an image to test that LDAP server:

FROM ubuntu
RUN apt-get -y install ldap-utils
RUN touch /root/.bash_aliases
RUN echo "alias lds='ldapsearch -H ldap://internalopenldap -LL -b
ou=Users,dc=openstack,dc=org -D cn=admin,dc=openstack,dc=org -w
password'" > /root/.bash_aliases
ENTRYPOINT bash

You can expose the 'openldap' container as 'internalopenldap' within the test image with --link:

 docker run -it --rm --name ldp --link openldap:internalopenldap ldaptest

Then, if you type 'lds', that alias will work:

ldapsearch -H ldap://internalopenldap ...

That would return people. Meaning internalopenldap is correctly reached from the ldaptest image.

Of course, docker 1.7 will add libnetwork, which provides a native Go implementation for connecting containers. See the blog post.
It introduced a more complete architecture, with the Container Network Model (CNM)

That will Update the Docker CLI with new “network” commands, and document how the “-net” flag is used to assign containers to networks.

docker 1.10 has a new section Network-scoped alias, now officially documented in network connect:

While links provide private name resolution that is localized within a container, the network-scoped alias provides a way for a container to be discovered by an alternate name by any other container within the scope of a particular network.
Unlike the link alias, which is defined by the consumer of a service, the network-scoped alias is defined by the container that is offering the service to the network.

Continuing with the above example, create another container in isolated_nw with a network alias.

$ docker run --net=isolated_nw -itd --name=container6 -alias app busybox
8ebe6767c1e0361f27433090060b33200aac054a68476c3be87ef4005eb1df17

--alias=[]         

Add network-scoped alias for the container

You can use --link option to link another container with a preferred alias

You can pause, restart, and stop containers that are connected to a network. Paused containers remain connected and can be revealed by a network inspect. When the container is stopped, it does not appear on the network until you restart it.

If specified, the container's IP address(es) is reapplied when a stopped container is restarted. If the IP address is no longer available, the container fails to start.

One way to guarantee that the IP address is available is to specify an --ip-range when creating the network, and choose the static IP address(es) from outside that range. This ensures that the IP address is not given to another container while this container is not on the network.

$ docker network create --subnet 172.20.0.0/16 --ip-range 172.20.240.0/20 multi-host-network

$ docker network connect --ip 172.20.128.2 multi-host-network container2
$ docker network connect --link container1:c1 multi-host-network container2

The server will automatically abort connections over which no message has been received for the duration equal to the receive timeout (default is 10 mins). This is a DoS mitigation to prevent clients from forcing the server to have connections open for an indefinite amount of time.

Since the server aborts the connection because it has gone idle, the client gets this exception.

You can control how long the server allows a connection to go idle before aborting it by configuring the receive timeout on the server's binding. Credit: T.R.Vishwanath - MSFT

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

By default the @Transactional attribute works only when calling an annotated method on a reference obtained from applicationContext.

public class Bean {
  public void doStuff() {
    doTransactionStuff();
  }
  @Transactional
  public void doTransactionStuff() {

  }
}

This will open a transaction:

Bean bean = (Bean)appContext.getBean("bean");
bean.doTransactionStuff();

This will not:

Bean bean = (Bean)appContext.getBean("bean");
bean.doStuff();

Spring Reference: Using @Transactional

Note: In proxy mode (which is the default), only 'external' method calls coming in through the proxy will be intercepted. This means that 'self-invocation', i.e. a method within the target object calling some other method of the target object, won't lead to an actual transaction at runtime even if the invoked method is marked with @Transactional!

Consider the use of AspectJ mode (see below) if you expect self-invocations to be wrapped with transactions as well. In this case, there won't be a proxy in the first place; instead, the target class will be 'weaved' (i.e. its byte code will be modified) in order to turn @Transactional into runtime behavior on any kind of method.

To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.

class YourClass():

    def your_function(self, *args):

        self.callable_function(param) # if you need to pass any parameter

    def callable_function(self, *params): 
        print('Your param:', param)

I have found this better way , no need to remove data , just call the source of the remote content each time

$(document).ready(function() {
    $('.class').click(function() {
        var id = this.id;
        //alert(id);checking that have correct id
        $("#iframe").attr("src","url?id=" + id);
        $('#Modal').modal({ 
            show: true 
        });
    });
});

I got this problem after updating to Android Studio 2.3

Adding these lines in dependencies solved my problem

compile 'com.android.support:customtabs:25.2.0'  
compile 'com.android.support:palette-v7:25.2.0'

Change:

 data: JSON.stringify({ model: source })

To:

 data: {model: JSON.stringify(source)}

And in your controller you do this:

public void PartSourceAPI(string model)
{
       System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

   var result = js.Deserialize<PartSourceModel>(model);
}

If the url you use in jquery is /api/PartSourceAPI then the controller name must be api and the action(method) should be PartSourceAPI

You could use a lookahead:

re.split(r'[ ](?=[A-Z]+\b)', input)

This will split at every space that is followed by a string of upper-case letters which end in a word-boundary.

Note that the square brackets are only for readability and could as well be omitted.

If it is enough that the first letter of a word is upper case (so if you would want to split in front of Hello as well) it gets even easier:

re.split(r'[ ](?=[A-Z])', input)

Now this splits at every space followed by any upper-case letter.

Use as variable to cast the Viewbag data to your desired class in view.

@{

IEnumerable<WebApplication1.Models.Person> personlist = ViewBag.data as
IEnumerable<WebApplication1.Models.Person>;
// You may need to write WebApplication.Models.Person where WebApplication.Models is
  the namespace name where the Person class is defined. It is required so that view 
  can know about the class Person. 
}

In view write this

<td>
    @(personlist.FirstOrDefault().Name)
</td>

Sometimes size "picks the wrong one" and returns a hash (which is what count would do)

In that case, use length to get an integer instead of hash.

If your views are in a class library assembly, which is useful for reuse of shared views among projects, then just doing what Adam suggests might not be enough. I still had issues even with that.

This worked for me. I now have intellisense and no compile errors on my views in a non-MVC project that I can then reference from multiple MVC websites.

As to why this still exists - MS doesn't consider it a priority, and values backwards compatibility over advancing their OS (at least in this instance).

A workaround I use is to use the "short names" for the directories in the path, instead of their standard, human-readable versions. So e.g. for C:\Program Files\ I would use C:\PROGRA~1\ You can find the short name equivalents using dir /x.

(Your question is still unclear on whether your code is calling printStackTrace() or this is being done by a logging handler.)

Here are some possible explanations about what might be happening:

• The logger / handler being used has been configured to only output the exception's message string, not a full stack trace.

• Your application (or some third-party library) is logging the exception using LOG.error(ex); rather than the 2-argument form of (for example) the log4j Logger method.

• The message is coming from somewhere different to where you think it is; e.g. it is actually coming some third-party library method, or some random stuff left over from earlier attempts to debug.

• The exception that is being logged has overloaded some methods to obscure the stacktrace. If that is the case, the exception won't be a genuine NullPointerException, but will be some custom subtype of NPE or even some unconnected exception.

I think that the last possible explanation is pretty unlikely, but people do at least contemplate doing this kind of thing to "prevent" reverse engineering. Of course it only really succeeds in making life difficult for honest developers.

Your method doesn't have any callbacks so there is no reason to use .CallBack(). You can simply return a Task with the desired values using .Returns() and Task.FromResult, e.g.:

MyType someValue=...;
mock.Setup(arg=>arg.DoSomethingAsync())        
    .Returns(Task.FromResult(someValue));

Update 2014-06-22

Moq 4.2 has two new extension methods to assist with this.

mock.Setup(arg=>arg.DoSomethingAsync())
    .ReturnsAsync(someValue);

mock.Setup(arg=>arg.DoSomethingAsync())        
    .ThrowsAsync(new InvalidOperationException());

Update 2016-05-05

As Seth Flowers mentions in the other answer, ReturnsAsync is only available for methods that return a Task<T>. For methods that return only a Task,

.Returns(Task.FromResult(default(object)))

can be used.

As shown in this answer, in .NET 4.6 this is simplified to .Returns(Task.CompletedTask);, e.g.:

mock.Setup(arg=>arg.DoSomethingAsync())        
    .Returns(Task.CompletedTask);

Swift solution for Stretch Fill, Aspect Fill and Aspect Fit

extension UIImage {
    enum ContentMode {
        case contentFill
        case contentAspectFill
        case contentAspectFit
    }
    
    func resize(withSize size: CGSize, contentMode: ContentMode = .contentAspectFill) -> UIImage? {
        let aspectWidth = size.width / self.size.width
        let aspectHeight = size.height / self.size.height
        
        switch contentMode {
        case .contentFill:
            return resize(withSize: size)
        case .contentAspectFit:
            let aspectRatio = min(aspectWidth, aspectHeight)
            return resize(withSize: CGSize(width: self.size.width * aspectRatio, height: self.size.height * aspectRatio))
        case .contentAspectFill:
            let aspectRatio = max(aspectWidth, aspectHeight)
            return resize(withSize: CGSize(width: self.size.width * aspectRatio, height: self.size.height * aspectRatio))
        }
    }
    
    private func resize(withSize size: CGSize) -> UIImage? {
        UIGraphicsBeginImageContextWithOptions(size, false, self.scale)
        defer { UIGraphicsEndImageContext() }
        draw(in: CGRect(x: 0.0, y: 0.0, width: size.width, height: size.height))
        return UIGraphicsGetImageFromCurrentImageContext()
    }
}

and to use you can do the following:

let image = UIImage(named: "image.png")!
let newImage = image.resize(withSize: CGSize(width: 200, height: 150), contentMode: .contentAspectFill)

Thanks to abdullahselek for his original solution.

public static String[] split(String input, int length) throws IllegalArgumentException {

    if(length == 0 || input == null)
        return new String[0];

    int lengthD = length * 2;

    int size = input.length();
    if(size == 0)
        return new String[0];

    int rep = (int) Math.ceil(size * 1d / length);

    ByteArrayInputStream stream = new ByteArrayInputStream(input.getBytes(StandardCharsets.UTF_16LE));

    String[] out = new String[rep];

You can find more information about the date pipe here, such as formats.

If you want to use it in your component, you can simply do

pipe = new DatePipe('en-US'); // Use your own locale

Now, you can simply use its transform method, which will be

const now = Date.now();
const myFormattedDate = this.pipe.transform(now, 'short');

In my use case I only wanted to see if a Bluetooth headset is connected for a VoIP app. The following solution worked for me:

public static boolean isBluetoothHeadsetConnected() {
    BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    return mBluetoothAdapter != null && mBluetoothAdapter.isEnabled()
            && mBluetoothAdapter.getProfileConnectionState(BluetoothHeadset.HEADSET) == BluetoothHeadset.STATE_CONNECTED;
} 

Of course you'll need the Bluetooth permission:

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

The command setwd("~/") should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/" as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.

As you have tagged the post using RStudio:

• In the bottom right window move the tab over to 'files'.
• Navigate through there to whichever folder you were planning to use as your working directory.
• Under 'more' click 'set as working directory'

You will now have set the folder as your working directory. Use the command getwd() to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd with that string as the argument, so that each time you run the script you use the same directory.

For example at the top of my script I would have:

work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)

Run Query:

    SP_RENAME '[TableName].[ColumnName]','NewNameForColumn'

A compiler specific difference between anonymous namespaces and static functions can be seen compiling the following code.

#include <iostream>

namespace
{
    void unreferenced()
    {
        std::cout << "Unreferenced";
    }

    void referenced()
    {
        std::cout << "Referenced";
    }
}

static void static_unreferenced()
{
    std::cout << "Unreferenced";
}

static void static_referenced()
{
    std::cout << "Referenced";
}

int main()
{
    referenced();
    static_referenced();
    return 0;
}

Compiling this code with VS 2017 (specifying the level 4 warning flag /W4 to enable warning C4505: unreferenced local function has been removed) and gcc 4.9 with the -Wunused-function or -Wall flag shows that VS 2017 will only produce a warning for the unused static function. gcc 4.9 and higher, as well as clang 3.3 and higher, will produce warnings for the unreferenced function in the namespace and also a warning for the unused static function.

When you say adding antMatchers doesnt help - what do you mean? antMatchers is exactly how you do it. Something like the following should work (obviously changing your URL appropriately):

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/authFailure").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()

If you are still not having any joy, then you will need to provide more details/stacktrace etc.

If the index of the dataset is a datetime and you want to filter that just by (for example) months, you can do following:

df.loc[df.index.month == 3]

That will filter the dataset for you by March.

I've used the following JavaScript library with great success:

https://github.com/balupton/jquery-history

It supports the HTML5 history API as well as a fallback method (using #) for older browsers.

This library is essentially a polyfill around `history.pushState'.
