We recently ran into this issue after upgrading to Office 2010 from Office 2007 - we had to manually change references in our project to version 14 of the Office Interops we use in some projects.

Hope that helps - took us a few days to figure it out.

The short answer is no (technically you can give whatever name of the class you want, but this will have no effect, unless you define your own CSS class - and remember - no dots in the class selector). The long answer is again no, because Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or view port size increases.

Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.

• Use rows to create horizontal groups of columns.
• Content should be placed within columns, and only columns may be immediate children of rows.
• Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
• Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
• Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
• If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
• Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, e.g. applying any .col-md-* class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg-* class is not present.

A possible solution to your problem is to define your own CSS class with desired width, let's say .col-half{width:XXXem !important} then add this class to elements you want along with original Bootstrap CSS classes.

If you implement Thread.UncaughtExceptionHandler in class that starts the Threads, you can set and then rethrow the exception:

public final class ThreadStarter implements Thread.UncaughtExceptionHandler{

private volatile Throwable initException;

    public void doSomeInit(){
        Thread t = new Thread(){
            @Override
            public void run() {
              throw new RuntimeException("UNCAUGHT");
            }
        };
        t.setUncaughtExceptionHandler(this);

        t.start();
        t.join();

        if (initException != null){
            throw new RuntimeException(initException);
        }

    }

    @Override
    public void uncaughtException(Thread t, Throwable e) {
        initException =  e;
    }    

}

Which causes the following output:

Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: UNCAUGHT

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

To know more about set ? visit this link

when it comes to your shell script,

[ "$DEBUG" == 'true' ] && set -x

Your script might have been printing some additional lines of information when the execution mode selected as DEBUG. Traditionally people used to enable debug mode when a script called with optional argument such as -d

Alex Robinson and bmju provided valuable information to understand cross-origin issues. I wanted to add that you may need to make an explicit OPTIONS call in your client code before making the desired GET/POST (e.g. against a CORS OAuth service endpoint). Your browser/library may not automatically handle the OPTIONS request. Gruber, this is one of the possible answers to your question.

A foreign key with a cascade delete means that if a record in the parent table is deleted, then the corresponding records in the child table will automatically be deleted. This is called a cascade delete.

You are saying in a opposite way, this is not that when you delete from child table then records will be deleted from parent table.

UPDATE 1:

ON DELETE CASCADE option is to specify whether you want rows deleted in a child table when corresponding rows are deleted in the parent table. If you do not specify cascading deletes, the default behaviour of the database server prevents you from deleting data in a table if other tables reference it.

If you specify this option, later when you delete a row in the parent table, the database server also deletes any rows associated with that row (foreign keys) in a child table. The principal advantage to the cascading-deletes feature is that it allows you to reduce the quantity of SQL statements you need to perform delete actions.

So it's all about what will happen when you delete rows from Parent table not from child table.

So in your case when user removes entries from CATs table then rows will be deleted from books table. :)

Hope this helps you :)

Error was due to file name of the lambda function. While creating the lambda function it will ask for Lambda function handler. You have to name it as your Python_File_Name.Method_Name. In this scenario I named it as lambda.lambda_handler (lambda.py is the file name).

Please find below the snapshot.

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

There is only a simple way to find modulo of 2^i numbers using bitwise.

There is an ingenious way to solve Mersenne cases as per the link such as n % 3, n % 7... There are special cases for n % 5, n % 255, and composite cases such as n % 6.

For cases 2^i, ( 2, 4, 8, 16 ...)

n % 2^i = n & (2^i - 1)

More complicated ones are hard to explain. Read up only if you are very curious.

Just use os.path.join to join your path with the filename and extension. Use sys.argv to access arguments passed to the script when executing it:

#!/usr/bin/env python3
# coding: utf-8

# import netCDF4 as nc
import numpy as np
import numpy.ma as ma
import csv as csv

import os.path
import sys

basedir = '/data/reu_data/soil_moisture/'
suffix = 'nc'


def read_fid(filename):
    fid = nc.MFDataset(filename,'r')
    fid.close()
    return fid

def read_var(file, varname):
    fid = nc.Dataset(file, 'r')
    out = fid.variables[varname][:]
    fid.close()
    return out


if __name__ == '__main__':
    if len(sys.argv) < 2:
        print('Please specify a year')

    else:
        filename = os.path.join(basedir, '.'.join((sys.argv[1], suffix)))
        time = read_var(ncf, 'time')
        lat = read_var(ncf, 'lat')
        lon = read_var(ncf, 'lon')
        soil = read_var(ncf, 'soilw')

Simply run the script like:

   # on windows-based systems
   python script.py year

   # on unix-based systems
   ./script.py year

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

To access helpers from your own controllers, just use:

To convert the object to a byte array use the concept of Serialization and De-serialization.

The complete conversion from object to byte array explained in is tutorial.

It's checking the return value ($?) of grep. In this case it's comparing it to 0 (success).

Usually when you see something like this (checking the return value of grep) it's checking to see whether the particular string was detected. Although the redirect to /dev/null isn't necessary, the same thing can be accomplished using -q.

If you are using bootstrap wrap your label and input with a div of a "checkbox" or "checkbox-inline" class.

<li>
    <div class="checkbox">
        <label><input type="checkbox" value="">Option 1</label>
    </div>
</li>

I would like to provide two methods in this answer, solution based on "z score" and solution based on "IQR".

The code provided in this answer works on both single dim numpy array and multiple numpy array.

Let's import some modules firstly.

import collections
import numpy as np
import scipy.stats as stat
from scipy.stats import iqr

z score based method

This method will test if the number falls outside the three standard deviations. Based on this rule, if the value is outlier, the method will return true, if not, return false.

def sd_outlier(x, axis = None, bar = 3, side = 'both'):
    assert side in ['gt', 'lt', 'both'], 'Side should be `gt`, `lt` or `both`.'

    d_z = stat.zscore(x, axis = axis)

    if side == 'gt':
        return d_z > bar
    elif side == 'lt':
        return d_z < -bar
    elif side == 'both':
        return np.abs(d_z) > bar

IQR based method

This method will test if the value is less than q1 - 1.5 * iqr or greater than q3 + 1.5 * iqr, which is similar to SPSS's plot method.

def q1(x, axis = None):
    return np.percentile(x, 25, axis = axis)

def q3(x, axis = None):
    return np.percentile(x, 75, axis = axis)

def iqr_outlier(x, axis = None, bar = 1.5, side = 'both'):
    assert side in ['gt', 'lt', 'both'], 'Side should be `gt`, `lt` or `both`.'

    d_iqr = iqr(x, axis = axis)
    d_q1 = q1(x, axis = axis)
    d_q3 = q3(x, axis = axis)
    iqr_distance = np.multiply(d_iqr, bar)

    stat_shape = list(x.shape)

    if isinstance(axis, collections.Iterable):
        for single_axis in axis:
            stat_shape[single_axis] = 1
    else:
        stat_shape[axis] = 1

    if side in ['gt', 'both']:
        upper_range = d_q3 + iqr_distance
        upper_outlier = np.greater(x - upper_range.reshape(stat_shape), 0)
    if side in ['lt', 'both']:
        lower_range = d_q1 - iqr_distance
        lower_outlier = np.less(x - lower_range.reshape(stat_shape), 0)

    if side == 'gt':
        return upper_outlier
    if side == 'lt':
        return lower_outlier
    if side == 'both':
        return np.logical_or(upper_outlier, lower_outlier)

Finally, if you want to filter out the outliers, use a numpy selector.

Have a nice day.

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1, 
        concat(round(( surveys/employees * 100 ),2),'%') AS percentage
    FROM a_test
    GROUP BY employees

Correct, np.log(x) is the Natural Log (base e log) of x.

For other bases, remember this law of logs: log-b(x) = log-k(x) / log-k(b) where log-b is the log in some arbitrary base b, and log-k is the log in base k, e.g.

here k = e

l = np.log(x) / np.log(100)

and l is the log-base-100 of x

I think it bears repeating: html_safe does not HTML-escape your string. In fact, it will prevent your string from being escaped.

<%= "<script>alert('Hello!')</script>" %>

will put:

<script>alert('Hello!')</script>

into your HTML source (yay, so safe!), while:

<%= "<script>alert('Hello!')</script>".html_safe %>

will pop up the alert dialog (are you sure that's what you want?). So you probably don't want to call html_safe on any user-entered strings.

I know it's an old topic but your illustration is not correct, the source code sets up the clip matrix correct.

[fov * aspectRatio][        0        ][        0              ][        0       ]
[        0        ][       fov       ][        0              ][        0       ]
[        0        ][        0        ][(far+near)/(far-near)  ][(2*near*far)/(near-far)]
[        0        ][        0        ][        1              ][        0       ]

some addition to your things:

This clip matrix works only if you are projecting on static 2D plane if you want to add camera movement and rotation:

viewMatrix = clipMatrix * cameraTranslationMatrix4x4 * cameraRotationMatrix4x4;

this lets you rotate the 2D plane and move it around..-

You can sed's -i option to edit in-place without using temporary file:

 sed -i '/^$/d' file

At the first you have to set focus on selected textbox object and next you set the value.

$('#inputID').focus();
$('#inputID').val('someValue')

You're half way there on your own. To implement a refresh, you'd just wrap what you already have in a function on the scope:

function PersonListCtrl($scope, $http) {
  $scope.loadData = function () {
     $http.get('/persons').success(function(data) {
       $scope.persons = data;
     });
  };

  //initial load
  $scope.loadData();
}

then in your markup

<div ng-controller="PersonListCtrl">
    <ul>
        <li ng-repeat="person in persons">
            Name: {{person.name}}, Age {{person.age}}
        </li>
    </ul>
   <button ng-click="loadData()">Refresh</button>
</div>

As far as "accessing your model", all you'd need to do is access that $scope.persons array in your controller:

for example (just puedo code) in your controller:

$scope.addPerson = function() {
     $scope.persons.push({ name: 'Test Monkey' });
};

Then you could use that in your view or whatever you'd want to do.

Both answers to this questions are correct, but I was still missing a complete, short solution to backup a Github repository into a local file. The gist is available here, feel free to fork or adapt to your needs.

backup.sh:

#!/bin/bash
# Backup the repositories indicated in the command line
# Example:
# bin/backup user1/repo1 user1/repo2
set -e
for i in $@; do
  FILENAME=$(echo $i | sed 's/\//-/g')
  echo "== Backing up $i to $FILENAME.bak"
  git clone [email protected]:$i $FILENAME.git --mirror
  cd "$FILENAME.git"
  git bundle create ../$FILENAME.bak --all
  cd ..
  rm -rf $i.git
  echo "== Repository saved as $FILENAME.bak"
done

restore.sh:

#!/bin/bash
# Restore the repository indicated in the command line
# Example:
# bin/restore filename.bak
set -e

FOLDER_NAME=$(echo $1 | sed 's/.bak//')
git clone --bare $1 $FOLDER_NAME.git

Using mongoose.js you can count documents,

• count all

const count = await Schema.countDocuments();

• count specific

const count = await Schema.countDocuments({ key: value });

After some more research, it appears, for Mozilla/Firefox, that Array.sort() uses mergesort. See the code here.

Had a similar issue, it turned out the listening port printed was different from what it actually was. Typos in the request string or listening function might make the target server appear to not exist.

This might help

    public Image ResizeImage(Image source, RectangleF destinationBounds)
    {
        RectangleF sourceBounds = new RectangleF(0.0f,0.0f,(float)source.Width, (float)source.Height);
        RectangleF scaleBounds = new RectangleF();

        Image destinationImage = new Bitmap((int)destinationBounds.Width, (int)destinationBounds.Height);
        Graphics graph = Graphics.FromImage(destinationImage);
        graph.InterpolationMode =
            System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;

        // Fill with background color
        graph.FillRectangle(new SolidBrush(System.Drawing.Color.White), destinationBounds);

        float resizeRatio, sourceRatio;
        float scaleWidth, scaleHeight;

        sourceRatio = (float)source.Width / (float)source.Height;

        if (sourceRatio >= 1.0f)
        {
            //landscape
            resizeRatio = destinationBounds.Width / sourceBounds.Width;
            scaleWidth = destinationBounds.Width;
            scaleHeight = sourceBounds.Height * resizeRatio;
            float trimValue = destinationBounds.Height - scaleHeight;
            graph.DrawImage(source, 0, (trimValue / 2), destinationBounds.Width, scaleHeight);
        }
        else
        {
            //portrait
            resizeRatio = destinationBounds.Height/sourceBounds.Height;
            scaleWidth = sourceBounds.Width * resizeRatio;
            scaleHeight = destinationBounds.Height;
            float trimValue = destinationBounds.Width - scaleWidth;
            graph.DrawImage(source, (trimValue / 2), 0, scaleWidth, destinationBounds.Height);
        }

        return destinationImage;

    }

Note the InterpolationMode.HighQualityBicubic -> this is generally a good tradeoff between performance and results.

Try this

    final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
    scrollview.post(new Runnable() {
       @Override
       public void run() {
         scrollview.fullScroll(ScrollView.FOCUS_DOWN);
       }
    });

Remove numbers, underscore, white-spaces and special characters from the string sentence.

str.replace(/[0-9`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi,'');

Demo

In Android Studio 1.2.1.1

Just copy the image and paste the image into the app > res > drawable folder and it will shows you "Choose Destination Directory" popup screen as shown below screen

Now you can select option whatever resolution you want to place and if you want to view the those image into the folders then simply right click on the drawable folder > select copy paths option and open it. It will help you.

Under the "Goto" menu, Control + M is Jump to Matching Bracket. Works for parentheses as well.

I solved this with Access options.

Go to the Office Button --> Access Options --> Trust Center --> Trust Center Settings Button --> Message Bar

In the right hand pane I selected the radio button "Show the message bar in all applications when content has been blocked."

Closed Access, reopened the database and got the warning for blocked content again.

You could use the System.Net.Mail.MailMessage class of the .NET framework.

You can find the MSDN documentation here.

Here is a simple example (code snippet):

using System.Net;
using System.Net.Mail;
using System.Net.Mime;

...
try
{

   SmtpClient mySmtpClient = new SmtpClient("my.smtp.exampleserver.net");

    // set smtp-client with basicAuthentication
    mySmtpClient.UseDefaultCredentials = false;
   System.Net.NetworkCredential basicAuthenticationInfo = new
      System.Net.NetworkCredential("username", "password");
   mySmtpClient.Credentials = basicAuthenticationInfo;

   // add from,to mailaddresses
   MailAddress from = new MailAddress("[email protected]", "TestFromName");
   MailAddress to = new MailAddress("[email protected]", "TestToName");
   MailMessage myMail = new System.Net.Mail.MailMessage(from, to);

   // add ReplyTo
   MailAddress replyTo = new MailAddress("[email protected]");
   myMail.ReplyToList.Add(replyTo);

   // set subject and encoding
   myMail.Subject = "Test message";
   myMail.SubjectEncoding = System.Text.Encoding.UTF8;

   // set body-message and encoding
   myMail.Body = "<b>Test Mail</b><br>using <b>HTML</b>.";
   myMail.BodyEncoding = System.Text.Encoding.UTF8;
   // text or html
   myMail.IsBodyHtml = true;

   mySmtpClient.Send(myMail);
}

catch (SmtpException ex)
{
  throw new ApplicationException
    ("SmtpException has occured: " + ex.Message);
}
catch (Exception ex)
{
   throw ex;
}

Define a new handler and runnable:

private Handler handler = new Handler(Looper.getMainLooper());
private Runnable runnable = new Runnable() {
        @Override
        public void run() {
            // Do what ever you want
        }
    };

Call post delayed:

handler.postDelayed(runnable, sleep_time);

Remove your callback from your handler:

handler.removeCallbacks(runnable);

shopList = [] 
maxLengthList = 6
while len(shopList) < maxLengthList:
    item = input("Enter your Item to the List: ")
    shopList.append(item)
    print shopList
print "That's your Shopping List"
print shopList

This command works !! mvn "-DTest=JoinTeamTestCases#validateJoinTeam" test Note that "-DTest" starts with UPPER CASE 'T'.

In my case , aLengthMenu is not working. So i used this. And it is working.

jQuery('#dyntable3').dataTable({            
            oLanguage: {sLengthMenu: "<select>"+
            "<option value='100'>100</option>"+
            "<option value='200'>200</option>"+
            "<option value='300'>300</option>"+
            "<option value='-1'>All</option>"+
            "</select>"},
            "iDisplayLength": 100

        });

Thank you

The constraints in the top-voted answer here worked for me, and I've pasted an image of the constraints below, as created in my storyboard.

I did hit two issues though that others should be aware of:

1. After adding constraints similar to those in in the accepted answer, I'd get the red autolayout error Need constraints for: X position or width. This was solved by adding a UILabel as a subview of the stack view.

   I'm adding the subviews programmatically, so I originally had no subviews on the storyboard. To get rid of the autolayout errors, add a subview to the storyboard, then remove it on load before adding your real subviews and constraints.

2. I originally attempted to add UIButtons to the UIStackView. The buttons and views would load, but the scroll view would not scroll. This was solved by adding UILabels to the Stack View instead of buttons. Using the same constraints, this view hierarchy with the UILabels scrolls but the UIButtons does not.

   I'm confused by this issue, as the UIButtons do seem to have an IntrinsicContentSize (used by the Stack View). If anyone knows why the buttons don't work, I'd love to know why.

Here is my view hierarchy and constraints, for reference:

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

http://www.codeguru.com/cpp/cpp/article.php/c17401/C-Tutorial-PointertoMember-Function.htm

If you're getting your timestamps from System.currentTimeMillis(), then your time variables should be longs.

I faced the same problem. Updating bash_profile with the following lines, solved the problem for me:

export JAVA_HOME='/usr/'

export PATH=${JAVA_HOME}/bin:$PATH

There is another asynchronous way use Blob and FileReader.

I didn't test the performance. But it is a different way of thinking.

function arrayBufferToBase64( buffer, callback ) {
    var blob = new Blob([buffer],{type:'application/octet-binary'});
    var reader = new FileReader();
    reader.onload = function(evt){
        var dataurl = evt.target.result;
        callback(dataurl.substr(dataurl.indexOf(',')+1));
    };
    reader.readAsDataURL(blob);
}

//example:
var buf = new Uint8Array([11,22,33]);
arrayBufferToBase64(buf, console.log.bind(console)); //"CxYh"

This solution is better. Some of the more popular options on here don't correct handle checkboxes when the checkbox is not checked.

       getData: function(element){
      //@todo may need additional logic for radio buttons
      var select = $(element).find('select');
      var input = $(element).find('input');
      var inputs = $.merge(select,input);
      var data = {};
      //console.log(input,'input');
      $.each(inputs,function(){
        if($(this).attr('type') != undefined){
          switch($(this).attr('type')){
            case 'checkbox':
              data[$(this).attr('name')] = ( ($(this).attr('checked') == 'checked') ? $(this).val():0 );
              break;
            default:
              data[$(this).attr('name')] = $(this).val();
              break;
          }
        }
        else{
          data[$(this).attr('name')] = $(this).val();
        }
      })
      return data;
   }

To answer your question on how you can do it, you could get the entrySet from your map and then just put into the new map by using getValue as key and getKey as value.

But remember that keys in a Map are unique, which means if you have one value with two different key in your original map, only the second key (in iteration order) will be kep as value in the new map.

This worked for me

.modal-dialog,
.modal-content {
    /* 80% of window height */
    height: 80%;
}

.modal-body {
    /* 100% = dialog height, 120px = header + footer */
    max-height: calc(100% - 120px);
    overflow-y: scroll;
}

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

\\?\C:\my_dir

See this answer for description.

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

you should install a x server such as XMing. and keep the x server is running. config your putty like this :Connection-Data-SSH-X11-Enable X11 forwarding should be checked. and X display location : localhost:0

So I realize this is kind of old, but after much Googling, I couldn't find an answer I was happy with, so I came up with my own solution for breaking a FOR loop that immediately stops iteration, and thought I'd share it.

It requires the loop to be in a separate file, and exploits a bug in CMD error handling to immediately crash the batch processing of the loop file when redirecting the STDOUT of DIR to STDIN.

MainFile.cmd

ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO.
ECHO After LOOP
PAUSE

LOOP.cmd

FOR /L %%A IN (1,1,10) DO (
    ECHO %%A
    IF %%A EQU 3 DIR >&0 2>NUL  )
)

When run, this produces the following output. You'll notice that both iteration and execution of the loop stops when %A = 3.

:>MainFile.cmd

:>ECHO Simple test demonstrating loop breaking.

:>ECHO.


:>CMD /C Z:\LOOP.cmd

:>FOR /L %A IN (1 1 10) DO (
ECHO %A
 IF %A EQU 3 DIR         1>&0 2>NUL
)

:>(
ECHO 1
 IF 1 EQU 3 DIR          1>&0 2>NUL
)
1

:>(
ECHO 2
 IF 2 EQU 3 DIR          1>&0 2>NUL
)
2

:>(
ECHO 3
 IF 3 EQU 3 DIR          1>&0 2>NUL
)
3

:>ECHO.


:>ECHO After LOOP
After LOOP

:>PAUSE
Press any key to continue . . .

If you need to preserve a single variable from the loop, have the loop ECHO the result of the variable, and use a FOR /F loop in the MainFile.cmd to parse the output of the LOOP.cmd file.

Example (using the same LOOP.cmd file as above):

MainFile.cmd

@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
FOR /F "delims=" %%L IN ('CMD /C %~dp0\LOOP.cmd') DO SET VARIABLE=%%L
ECHO After LOOP
ECHO.
ECHO %VARIABLE%
ECHO.
PAUSE

Output:

:>MainFile.cmd

Simple test demonstrating loop breaking.

After LOOP

3

Press any key to continue . . .

If you need to preserve multiple variables, you'll need to redirect them to temporary files as shown below.

MainFile.cmd

@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO After LOOP
ECHO.
SET /P VARIABLE1=<%TEMP%\1
SET /P VARIABLE2=<%TEMP%\2
ECHO %VARIABLE1%
ECHO %VARIABLE2%
ECHO.
PAUSE

LOOP.cmd

@ECHO OFF
FOR /L %%A IN (1,1,10) DO (
    IF %%A EQU 1 ECHO ONE >%TEMP%\1
    IF %%A EQU 2 ECHO TWO >%TEMP%\2
    IF %%A EQU 3 DIR >&0 2>NUL
)

Output:

:>MainFile.cmd

Simple test demonstrating loop breaking.

After LOOP

ONE
TWO

Press any key to continue . . .

I hope others find this useful for breaking loops that would otherwise take too long to exit due to continued iteration.

The problem seems to be in the way how ng-model works with input and overwrites the name object, making it lost for ng-repeat.

As a workaround, one can use the following code:

<div ng-repeat="name in names">
    Value: {{name}}
    <input ng-model="names[$index]">                         
</div>

Hope it helps

I think it will have a syntactic benefit, since you'll no longer be "faking" dynamically added properties by using a dictionary.

That, and interop with dynamic languages I would think.

I am using blueJ for java programming. There is a way to clear the screen of it's terminal window. Try this:-

System.out.print ('\f');

this will clear whatever is printed before this line. But this does not work in command prompt.

Inspired by sverrir-sigmundarson's comment:

def time_to_sec(time_str):
    return sum(x * int(t) for x, t in zip([1, 60, 3600], reversed(time_str.split(":"))))

I believe you are looking for -maxdepth 1.

I wanted to keep a few recent stashes, but delete everything else.

Because all stashes get renumbered when you drop one, this is actually easy to do with while. To delete all stashes older than stash@{19}:

while git stash drop 'stash@{20}'; do true; done

I had some lint errors in Android Studio that occurred only when I generated a signed APK.

To avoid it, I added the following to build.gradle

android {
    lintOptions {
        checkReleaseBuilds false
    }
}

A solution similar to the one of @Nick G. by using filter, but make the parameter meaningful:

Implement an filter called relativedate which calculate the date relative to current date by the given parameter as diff. As a result, (0 | relativedate) means today and (1 | relativedate) means tomorrow.

.filter('relativedate', ['$filter', function ($filter) {
  return function (rel, format) {
    let date = new Date();
    date.setDate(date.getDate() + rel);
    return $filter('date')(date, format || 'yyyy-MM-dd')
  };
}]);

and your html:

<div ng-app="myApp">
    <div>Yesterday: {{-1 | relativedate}}</div>
    <div>Today: {{0 | relativedate}}</div>
    <div>Tomorrow: {{1 | relativedate}}</div>
</div>

document.getElementById("id").innerHTML == "" || null

or

$("element").html() == "" || null

Since I had troubles understanding this post here is a simple explanation for people like me. It is useful if:

• You DO NOT need Load Balacing.
• You DO NOT want to use nginx to do port forwarding.
• You DO want to do PORT FORWARDING according to specific subdomains using SRV record.

Then here is what you need to do:

SRV records:

_minecraft._tcp.1.12          IN SRV    1 100 25567 1.12.<your-domain-name.com>.
_minecraft._tcp.1.13          IN SRV    1 100 25566 1.13.<your-domain-name.com>.

(I did not need a srv record for 1.14 since my 1.14 minecraft server was already on the 25565 port which is the default port of minecraft.)

And the A records:

1.12                          IN A      <your server IP>
1.13                          IN A      <your server IP>
1.14                          IN A      <your server IP>

This question comes up first in the Google search for this type error, but does not have a general answer about the cause of the error. The poster's unique problem was the use of an inappropriate object type as the main argument for plt.imshow(). A more general answer is that plt.imshow() wants an array of floats and if you don't specify a float, numpy, pandas, or whatever else, might infer a different data type somewhere along the line. You can avoid this by specifying a float for the dtype argument is the constructor of the object.

See the Numpy documentation here.

See the Pandas documentation here

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

In most of the modern single page applications, we indeed have to store the token somewhere on the client side (most common use case - to keep the user logged in after a page refresh).

There are a total of 2 options available: Web Storage (session storage, local storage) and a client side cookie. Both options are widely used, but this doesn't mean they are very secure.

Tom Abbott summarizes well the JWT sessionStorage and localStorage security:

Web Storage (localStorage/sessionStorage) is accessible through JavaScript on the same domain. This means that any JavaScript running on your site will have access to web storage, and because of this can be vulnerable to cross-site scripting (XSS) attacks. XSS, in a nutshell, is a type of vulnerability where an attacker can inject JavaScript that will run on your page. Basic XSS attacks attempt to inject JavaScript through form inputs, where the attacker puts <script>alert('You are Hacked');</script> into a form to see if it is run by the browser and can be viewed by other users.

To prevent XSS, the common response is to escape and encode all untrusted data. React (mostly) does that for you! Here's a great discussion about how much XSS vulnerability protection is React responsible for.

But that doesn't cover all possible vulnerabilities! Another potential threat is the usage of JavaScript hosted on CDNs or outside infrastructure.

Here's Tom again:

Modern web apps include 3rd party JavaScript libraries for A/B testing, funnel/market analysis, and ads. We use package managers like Bower to import other peoples’ code into our apps.

What if only one of the scripts you use is compromised? Malicious JavaScript can be embedded on the page, and Web Storage is compromised. These types of XSS attacks can get everyone’s Web Storage that visits your site, without their knowledge. This is probably why a bunch of organizations advise not to store anything of value or trust any information in web storage. This includes session identifiers and tokens.

Therefore, my conclusion is that as a storage mechanism, Web Storage does not enforce any secure standards during transfer. Whoever reads Web Storage and uses it must do their due diligence to ensure they always send the JWT over HTTPS and never HTTP.

It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

On Error Resume Next

DangerousOperationThatCouldCauseErrors

If Err Then
    WScript.StdErr.WriteLine "error " & Err.Number
    WScript.Quit 1
End If

Just use these command lines:

sudo apt-get update
sudo apt-get install oracle-java8-installer

You have to give height and width to that image.

eg. height : 200px and width : 200px also give border-radius:50%;

to create circle you have to give equal height and width

if you are using bootstrap then give height and width and img-circle class to img

Here's an adaptation of silvertab's solution, with generics retrofitted:

static <T> T[] concat(T[] a, T[] b) {
    final int alen = a.length;
    final int blen = b.length;
    final T[] result = (T[]) java.lang.reflect.Array.
            newInstance(a.getClass().getComponentType(), alen + blen);
    System.arraycopy(a, 0, result, 0, alen);
    System.arraycopy(b, 0, result, alen, blen);
    return result;
}

NOTE: See Joachim's answer for a Java 6 solution. Not only does it eliminate the warning; it's also shorter, more efficient and easier to read!

I guess that the most correct answer is: Use :nth-child (or, in this specific case, its counterpart :nth-last-child). Most only know this selector by its first argument to grab a range of items based on a calculation with n, but it can also take a second argument "of [any CSS selector]".

Your scenario could be solved with this selector: .commentList .comment:nth-last-child(1 of .comment)

But being technically correct doesn't mean you can use it, though, because this selector is as of now only implemented in Safari.

For further reading:

• https://drafts.csswg.org/selectors-4/#the-nth-child-pseudo
• http://caniuse.com/#search=nth-child

Dirty trick: You could as well use lambda expression to pass any code you want including the call with parameters.

this.Include(includes, () =>
{
    _context.Cars.Include(<parameters>);
});

If I may, Skurmedel's code is for python 2; to adapt it to python 3, change iteritems to items and add parenthesis to print. That could prevent beginners like me to bump into: AttributeError: 'dict' object has no attribute 'iteritems' and search elsewhere (e.g. Error “ 'dict' object has no attribute 'iteritems' ” when trying to use NetworkX's write_shp()) why this is happening.

def myfunc(**kwargs):
for k,v in kwargs.items():
   print("%s = %s" % (k, v))

myfunc(abc=123, efh=456)
# abc = 123

and:

def myfunc2(*args, **kwargs):
   for a in args:
       print(a)
   for k,v in kwargs.items():
       print("%s = %s" % (k, v))

Many times as API's are updated. We forgot to update SDK Managers. For accessing recent API's one should always have highest API Level updated if possible should also have other regularly used lower level APIs to accommodate backward compatibility.
Go to build.gradle (module.app) file change compileSdkVersion buildToolsVersion targetSdkVersion, all should have the highest level of API.

To expand one what CheeseConQueso is saying, here are the entire steps to update a view using PHPMyAdmin:

1. Run the following query: SHOW CREATE VIEW your_view_name
2. Expand the options and choose Full Texts
3. Press Go
4. Copy entire contents of the Create View column.
5. Make changes to the query in the editor of your choice
6. Run the query directly (without the CREATE VIEW... syntax) to make sure it runs as you expect it to.
7. Once you're satisfied, click on your view in the list on the left to browse its data and then scroll all the way to the bottom where you'll see a CREATE VIEW link. Click that.
8. Place a check in the OR REPLACE field.
9. In the VIEW name put the name of the view you are going to update.
10. In the AS field put the contents of the query that you ran while testing (without the CREATE VIEW... syntax).
11. Press Go

I hope that helps somebody. Special thanks to CheesConQueso for his/her insightful answer.

I'll add 2 points:

• "IN" is effectively serial ORs with parentheses around them
• AND has precedence over OR in every language I know

So, the 2 expressions are simply not equal.

WHERE some_col in (1,2,3,4,5) AND some_other_expr
--to the optimiser is this
WHERE
     (
     some_col = 1 OR
     some_col = 2 OR 
     some_col = 3 OR 
     some_col = 4 OR 
     some_col = 5
     )
     AND
     some_other_expr

So, when you break the IN clause up, you split the serial ORs up, and changed precedence.

Here's how you do it

With a clustered index the rows are stored physically on the disk in the same order as the index. Therefore, there can be only one clustered index.

With a non clustered index there is a second list that has pointers to the physical rows. You can have many non clustered indices, although each new index will increase the time it takes to write new records.

It is generally faster to read from a clustered index if you want to get back all the columns. You do not have to go first to the index and then to the table.

Writing to a table with a clustered index can be slower, if there is a need to rearrange the data.

As Obama says "Yes We Can". Here is the link to it. developers.google.com/#jquery

You need to use

Google

ajax.googleapis.com/ajax/libs/jqueryui/[VERSION NO]/jquery-ui.min.js
ajax.googleapis.com/ajax/libs/jqueryui/[VERSION NO]/themes/[THEME NAME]/jquery-ui.min.css

jQuery CDN

code.jquery.com/ui/[VERSION NO]/jquery-ui.min.js
code.jquery.com/ui/[VERSION NO]/themes/[THEME NAME]/jquery-ui.min.css

Microsoft

ajax.aspnetcdn.com/ajax/jquery.ui/[VERSION NO]/jquery-ui.min.js
ajax.aspnetcdn.com/ajax/jquery.ui/[VERSION NO]/themes/[THEME NAME]/jquery-ui.min.css

Find theme names here http://jqueryui.com/themeroller/ in gallery subtab

.

But i would not recommend you hosting from cdn for the following reasons

1. Although your chance of hit rate is good in case of Google CDN compared to others but it's still abysmally low.(any cdn not just google).
2. Loading via cdn you will have 3 requests one for jQuery.js, one for jQueryUI.js and one for your code. You might as will compress it on your local and load it as one single resource.

Add border-collapse:collapse to your table rule:

table { 
    border-collapse: collapse; 
}

Example

table {
  border-collapse: collapse;
}

tr {
  border-bottom: 1pt solid black;
}

<table>
  <tr><td>A1</td><td>B1</td><td>C1</td></tr>
  <tr><td>A2</td><td>B2</td><td>C2</td></tr>
  <tr><td>A2</td><td>B2</td><td>C2</td></tr>
</table>

Link

<script>
$(function(){
    $('.movie').click(function(){
        var this_href=$(this).attr('href');
        $.ajax({
            url:this_href,
            type:'post',
            cache:false,
            success:function(data)
            {
                $('#summary').html(data);
            }
        });
        return false;
    });
});
</script>

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

public string RemoveSpecial(string evalstr)
{
StringBuilder finalstr = new StringBuilder();
            foreach(char c in evalstr){
            int charassci = Convert.ToInt16(c);
            if (!(charassci >= 33 && charassci <= 47))// special char ???
             finalstr.append(c);
            }
return finalstr.ToString();
}

As a concept, the head is the latest revision in a branch. If you have more than one head per named branch you probably created it when doing local commits without merging, effectively creating an unnamed branch.

To have a "clean" repository, you should have one head per named branch and always merge to a named branch after you worked locally.

This is also true for Mercurial.

There are multiple ways to open a link in new tab in using Selenium WebDriver.

Usecase A: Opening an adjacent blank tab and iterating through an iterator

• Code Block:

  import java.util.Iterator;
  import java.util.Set;
  
  import org.openqa.selenium.JavascriptExecutor;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.chrome.ChromeDriver;
  import org.openqa.selenium.chrome.ChromeOptions;
  import org.openqa.selenium.support.ui.ExpectedConditions;
  import org.openqa.selenium.support.ui.WebDriverWait;
  
  public class NewTab_blank_iterator {
  
      public static void main(String[] args) {
  
          System.setProperty("webdriver.chrome.driver","C:\\WebDrivers\\chromedriver.exe");
          ChromeOptions options = new ChromeOptions();
          options.addArguments("start-maximized");
          WebDriver driver =  new ChromeDriver(options); 
          driver.get("https://mail.google.com/");
          String firstWindowHandle = driver.getWindowHandle();
          System.out.println("First Window Handle is: "+firstWindowHandle);
          // Opening an adjacent blank tab
          ((JavascriptExecutor)driver).executeScript("window.open('','_blank');");
          new WebDriverWait(driver, 10).until(ExpectedConditions.numberOfWindowsToBe(2));
          Set<String> allWindowHandles = driver.getWindowHandles();
          // Using iterator
          Iterator<String> itr = allWindowHandles.iterator();
          while(itr.hasNext()) {
              String nextWindow = itr.next();
              if(!firstWindowHandle.equalsIgnoreCase(nextWindow)) {
                  driver.switchTo().window(nextWindow);
                  System.out.println("New Tab Window Handle is: "+nextWindow);
              }
          }
      }
  }
  

• Console Output:

• Browser Snapshot:

1. Open your sql file in a text editor (like Notepad)
2. Select All -> Copy
3. Go to phpMyAdmin, select your database and go to SQL tab
4. Paste the content you have copied in clipboard
5. It might popup a javascript error, ignore it
6. Execute

CTRL + SHIFT + F will auto format your code(whether it is highlighted or non highlighted).

The main difference between them you can find as follows:

HashSet

• It does not allow duplicate keys.
• Even it is not synchronized, so this will have better performance.
• It allows a null key.
• HashSet can be used when you want to maintain a unique list.
• HashSet implements Set interface and it is backed by the hash table(actually HashMap instance).
• HashSet stores objects.
• HashSet doesn’t allow duplicate elements but null values are allowed.
• This interface doesn’t guarantee that order will remain constant over time.

HashMap

• It allows duplicate keys. It is not synchronized, so this will have better performance.
• HashMap does not maintain insertion order.
• The order is defined by the Hash function.
• It is not Thread Safe
• It allows null for both key and value.
• It allows one null key and as many null values as you like.
• HashMap is a Hash table-based implementation of the Map interface.
• HashMap store object as key and value pair.
• HashMap does not allow duplicate keys but null keys and values are allowed.
• Ordering of the element is not guaranteed overtime.

I added .UseUrls("https://localhost:<some port>/") to the Program.cs. This seemed to do the trick for me!

a = a.split("\n");

Note that splitting returns the new array, rather than just assigning it to the original string. You need to explicitly store it in a variable.

Using toPrecision method:

var a = 1.2345
a.toPrecision(2)

// result "1.2"

jQuery methods returns the set they were applied on.

Use .appendTo:

var $div = $('<div />').appendTo('body');
$div.attr('id', 'holdy');

if you have a list a and then following statements

list<int>::iterator it; // declare an iterator
    list<int>::const_iterator cit; // declare an const iterator 
    it=a.begin();
    cit=a.begin();

you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.

*it=*it+1;//returns no error
    *cit=*cit+1;//this will return error

Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.

Rename your file back.

Steps:
1. Add accept attribute to input tag
2. Validate with javascript
3. Add server side validation to verify if the content is really an expected file type

For HTML and javascript:

<html>
<body>
<input name="image" type="file" id="fileName" accept=".jpg,.jpeg,.png" onchange="validateFileType()"/>
<script type="text/javascript">
    function validateFileType(){
        var fileName = document.getElementById("fileName").value;
        var idxDot = fileName.lastIndexOf(".") + 1;
        var extFile = fileName.substr(idxDot, fileName.length).toLowerCase();
        if (extFile=="jpg" || extFile=="jpeg" || extFile=="png"){
            //TO DO
        }else{
            alert("Only jpg/jpeg and png files are allowed!");
        }   
    }
</script>
</body>
</html>

Explanation:

1. The accept attribute filters the files that will be displayed in the file chooser popup. However, it is not a validation. It is only a hint to the browser. The user can still change the options in the popup.
2. The javascript only validates for file extension, but cannot really verify if the select file is an actual jpg or png.
3. So you have to write for file content validation on server side.

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

I would add that HTMLElement has a built-in .blur method as well.

Here's a demo using both .focus and .blur which work in similar ways.

const input = document.querySelector("#myInput");

<input id="myInput" value="Some Input">_x000D_
_x000D_
<button type="button" onclick="input.focus()">Focus</button>_x000D_
<button type="button" onclick="input.blur()">Lose focus</button>

There is no way you can hidde the keyboard properly with js because its a OS problem, so one thing you can easy do to "hidde" the keyboard, is instead of using an input Element you can make any "non-input html element" a key listener element just by adding the [tabindex] attribute, and then you can easily listen the keydown and keyup events and store the "$event.target.value" in a variable to get the input.

If it is a c-string (null-terminated array of type char), you can do something like:

#include <stdlib.h>
char str[] = "3.14159";
double num = atof(str);

If it is a C++ string, just use the c_str() method:

double num = atof( cppstr.c_str() );

atof() will convert the string to a double, returning 0 on failure. The function is documented here: http://www.cplusplus.com/reference/clibrary/cstdlib/atof.html

If you had use strict turned on, you would have found out that $++foo doesn't make any sense.

Here's how to do it:

use strict;
use warnings;

my $file = 'SnPmaster.txt';
open my $info, $file or die "Could not open $file: $!";

while( my $line = <$info>)  {   
    print $line;    
    last if $. == 2;
}

close $info;

This takes advantage of the special variable $. which keeps track of the line number in the current file. (See perlvar)

If you want to use a counter instead, use

my $count = 0;
while( my $line = <$info>)  {   
    print $line;    
    last if ++$count == 2;
}

I also had the same error:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field repository in com.kalsym.next.gen.campaign.controller.CampaignController required a bean of type 'com.kalsym.next.gen.campaign.data.CustomerRepository' that could not be found.


Action:

Consider defining a bean of type 'com.kalsym.next.gen.campaign.data.CustomerRepository' in your configuration.de here

And my packages were constructed in the same way as mentioned in the accepted answer. I fixed my issue by adding EnableMongoRepositories annotation in the main class like this:

@SpringBootApplication
@EnableMongoRepositories(basePackageClasses = CustomerRepository.class)
public class CampaignAPI {

    public static void main(String[] args) {
        SpringApplication.run(CampaignAPI.class, args);
    }
}

If you need to add multiple don't forget the curly braces:

@EnableMongoRepositories(basePackageClasses
    = {
        MSASMSRepository.class, APartyMappingRepository.class
    })

With closure:

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

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

and using

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

This is a hack to make inner functions (functions defined inside other functions) work more like they should. In javascript when you define one function inside another this automatically gets set to the global scope. This can be confusing because you expect this to have the same value as in the outer function.

var car = {};
car.starter = {};

car.start = function(){
    var that = this;

    // you can access car.starter inside this method with 'this'
    this.starter.active = false;

    var activateStarter = function(){
        // 'this' now points to the global scope
        // 'this.starter' is undefined, so we use 'that' instead.
        that.starter.active = true;

        // you could also use car.starter, but using 'that' gives
        // us more consistency and flexibility
    };

    activateStarter();

};

This is specifically a problem when you create a function as a method of an object (like car.start in the example) then create a function inside that method (like activateStarter). In the top level method this points to the object it is a method of (in this case, car) but in the inner function this now points to the global scope. This is a pain.

Creating a variable to use by convention in both scopes is a solution for this very general problem with javascript (though it's useful in jquery functions, too). This is why the very general sounding name that is used. It's an easily recognizable convention for overcoming a shortcoming in the language.

Like El Ronnoco hints at Douglas Crockford thinks this is a good idea.

This code has worked for me:

WebClient wc = new WebClient();
wc.Proxy.Credentials = CredentialCache.DefaultCredentials;

Background

A Docker container runs a process (the "command" or "entrypoint") that keeps it alive. The container will continue to run as long as the command continues to run.

In your case, the command (/bin/bash, by default, on centos:latest) is exiting immediately (as bash does when it's not connected to a terminal and has nothing to run).

Normally, when you run a container in daemon mode (with -d), the container is running some sort of daemon process (like httpd). In this case, as long as the httpd daemon is running, the container will remain alive.

What you appear to be trying to do is to keep the container alive without a daemon process running inside the container. This is somewhat strange (because the container isn't doing anything useful until you interact with it, perhaps with docker exec), but there are certain cases where it might make sense to do something like this.

(Did you mean to get to a bash prompt inside the container? That's easy! docker run -it centos:latest)

Solution

A simple way to keep a container alive in daemon mode indefinitely is to run sleep infinity as the container's command. This does not rely doing strange things like allocating a TTY in daemon mode. Although it does rely on doing strange things like using sleep as your primary command.

$ docker run -d centos:latest sleep infinity
$ docker ps
CONTAINER ID  IMAGE         COMMAND          CREATED       STATUS       PORTS NAMES
d651c7a9e0ad  centos:latest "sleep infinity" 2 seconds ago Up 2 seconds       nervous_visvesvaraya

Alternative Solution

As indicated by cjsimon, the -t option allocates a "pseudo-tty". This tricks bash into continuing to run indefinitely because it thinks it is connected to an interactive TTY (even though you have no way to interact with that particular TTY if you don't pass -i). Anyway, this should do the trick too:

$ docker run -t -d centos:latest

Not 100% sure whether -t will produce other weird interactions; maybe leave a comment below if it does.

It seems that you need to define formats for both date and time part or use String-based formatting. For example:

Gson gson = new GsonBuilder()
   .setDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz").create();

or using java.text.DateFormat

Gson gson = new GsonBuilder()
   .setDateFormat(DateFormat.FULL, DateFormat.FULL).create();

or do it with serializers:

I believe that formatters cannot produce timestamps, but this serializer/deserializer-pair seems to work

JsonSerializer<Date> ser = new JsonSerializer<Date>() {
  @Override
  public JsonElement serialize(Date src, Type typeOfSrc, JsonSerializationContext 
             context) {
    return src == null ? null : new JsonPrimitive(src.getTime());
  }
};

JsonDeserializer<Date> deser = new JsonDeserializer<Date>() {
  @Override
  public Date deserialize(JsonElement json, Type typeOfT,
       JsonDeserializationContext context) throws JsonParseException {
    return json == null ? null : new Date(json.getAsLong());
  }
};

Gson gson = new GsonBuilder()
   .registerTypeAdapter(Date.class, ser)
   .registerTypeAdapter(Date.class, deser).create();

If using Java 8 or above you should use the above serializers/deserializers like so:

JsonSerializer<Date> ser = (src, typeOfSrc, context) -> src == null ? null
            : new JsonPrimitive(src.getTime());

JsonDeserializer<Date> deser = (jSon, typeOfT, context) -> jSon == null ? null : new Date(jSon.getAsLong());

I solved this by using a small function to convert version strings to plain integer values that can be compared:

function versionToInt() {
  local IFS=.
  parts=($1)
  let val=1000000*parts[0]+1000*parts[1]+parts[2]
  echo $val
}

This makes two important assumptions:

1. Input is a "normal SemVer string"
2. Each part is between 0-999

For example

versionToInt 12.34.56  # --> 12034056
versionToInt 1.2.3     # -->  1002003

Example testing whether npm command meets minimum requirement ...

NPM_ACTUAL=$(versionToInt $(npm --version))  # Capture npm version
NPM_REQUIRED=$(versionToInt 4.3.0)           # Desired version
if [ $NPM_ACTUAL \< $NPM_REQUIRED ]; then
  echo "Please update to npm@latest"
  exit 1
fi

My code for MyMediaConnectorClient:

public class MyMediaConnectorClient implements MediaScannerConnectionClient {

    String _fisier;
    MediaScannerConnection MEDIA_SCANNER_CONNECTION;

    public MyMediaConnectorClient(String nume) {
        _fisier = nume;
    }

    public void setScanner(MediaScannerConnection msc){
        MEDIA_SCANNER_CONNECTION = msc;
    }

    @Override
    public void onMediaScannerConnected() {
        MEDIA_SCANNER_CONNECTION.scanFile(_fisier, null);
    }

    @Override
    public void onScanCompleted(String path, Uri uri) {
        if(path.equals(_fisier))
            MEDIA_SCANNER_CONNECTION.disconnect();
    }
}

You will likely encounter problems if you ever try to take advantage of caching. Proxies are not going to look in the GET body to see if the parameters have an impact on the response.

If you use Git for Windows, this is likely your issue

I've had the same problem and stash, hard reset, clean or even all of them was still leaving changes behind. What turned out to be the problem was the x file mode that was not set properly by git. This is a "known issue" with git for windows. The local changes show in gitk and git status as old mode 100755 new mode 100644, without any actual file differences.

The fix is to ignore the file mode:

git config core.filemode false

One way to do it is to set the image you want to display as a background in a container (td, div, span etc) and then adjust background-position to get the sprite you want.

This answer was last revised for Swift 5.3 and iOS 14.4 SDK.

Given some already obtained JSON data, you can use JSONDecoder to decode it into your Decodable model (or a collection of models).

let data: Data = /* obtain your JSON data */
let model = try JSONDecoder().decode(Model.self, from: data)

Such model must conform to the Decodable protocol and contain correct mapping between properties and JSON dictionary keys. As an example, consider the following JSON array containing search results of cities beginning with "Wa".

[
    {
        "id": 123,
        "city": "Washington",
        "region": "D.C.",
        "country": "United States"
    },
    {
        "id": 456,
        "city": "Warsaw",
        "region": "Mazowieckie",
        "country": "Poland"
    },
    ...
]

For that, you need to create a model that contains the correct properties of correct types. If you're using a web API, its documentation will be of great help here.

struct SearchResult: Decodable {
    let id: Int
    let city: String
    let region: String
    let country: String
}

Then decode the data with JSONDecoder:

let results = try JSONDecoder().decode([SearchResult].self, from: data)

Given a new array of decoded search results, call one of UITableView's functions to reload its data. Note that the decode function can throw an error which you must somehow handle.

To learn more about decoding custom types in Swift and more advanced usage of the Codable APIs, I recommend checking out this documentation article.

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

 LayoutInflater factory = LayoutInflater.from(this);
final View textEntryView = factory.inflate(R.layout.text_entry, null);
//text_entry is an Layout XML file containing two text field to display in alert dialog
final EditText input1 = (EditText) textEntryView.findViewById(R.id.EditText1);
final EditText input2 = (EditText) textEntryView.findViewById(R.id.EditText2);             
input1.setText("DefaultValue", TextView.BufferType.EDITABLE);
input2.setText("DefaultValue", TextView.BufferType.EDITABLE);
final AlertDialog.Builder alert = new AlertDialog.Builder(this);

alert.setIcon(R.drawable.icon)
     .setTitle("Enter the Text:")
     .setView(textEntryView)
     .setPositiveButton("Save", 
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int whichButton) {
                    Log.i("AlertDialog","TextEntry 1 Entered "+input1.getText().toString());
                    Log.i("AlertDialog","TextEntry 2 Entered "+input2.getText().toString());
                    /* User clicked OK so do some stuff */
             }
         })
     .setNegativeButton("Cancel",
         new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog,
                    int whichButton) {
             }
         });
alert.show();

For environment variable, we have to need to follow some steps.

You can use Chocolatey to install cyg-get and then install your packages with it.

For example:

choco install cyg-get

Then:

cyg-get install my-package

I know that I have this problem over and over when I deploy my application on a new server because I'm using this driver to connect to a Excel file. So here it is what I'm doing lately.

There's a Windows Server 2008 R2, I install the Access drivers for a x64 bit machine and I get rid of this message, which makes me very happy just to bump into another.

This one here below works splendidly on my dev machine but on server gives me an error even after installing the latest ODBC drivers, which I think this is the problem, but this is how I solved it.

private const string OledbProviderString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\OlsonWindows.xls;Extended Properties=\"Excel 8.0;HDR=YES\"";

I replace with the new provider like this below:

private const string OledbProviderString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xlsx;Extended Properties='Excel 12.0;HDR=YES;';";

But as I do this, there's one thing you should notice. Using the .xlsx file extension and Excel version is 12.0.

After I get into this error message Error: "Could Not Find Installable ISAM", I decide to change the things a little bit like below:

private const string OledbProviderString =      @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xls;Extended Properties='Excel 8.0;HDR=YES;';"; 

and yes, I'm done with that nasty thing, but here I got another message The Microsoft Access database engine cannot open or write to the file 'time_zone'. It is already opened exclusively by another user, or you need permission to view and write its data. which tells me I'm not far away from solving it.

Maybe there's another process that opened the file meanwhile and all that I have to do is a restart and all will take start smoothly running as expected.

Elaborating on @Jonathan Ray I think this does the trick a bit better

import time
import inspect

def timed(f:callable):
    start = time.time()
    ret = f()
    elapsed = 1000*(time.time() - start)
    source_code=inspect.getsource(f).strip('\n') 
    logger.info(source_code+":  "+str(elapsed)+" seconds")
    return ret

It allows to take a regular line of code, say a = np.sin(np.pi) and transform it rather simply into

a = timed(lambda: np.sin(np.pi))

so that the timing is printed onto the logger and you can keep the same assignment of the result to a variable you might need for further work.

I suppose in Python 3.8 one could use the := but I do not have 3.8 yet

I just had this error too but it was masking another more relevant error message where the code was trying to store a 125 characters string in a 100 characters column:

DatabaseError: value too long for type character varying(100)

I had to debug through the code for the above message to show up, otherwise it displays

DatabaseError: current transaction is aborted

This is the simplest way.

Say, this is the div block I want to make clickable:

<div class="inner_headL"></div>

So put a href as follows:

<a href="#">
 <div class="inner_headL"></div>
</a>

Just consider the div block as a normal html element and enable the usual a href tag.
It works on FF at least.

Where x is the collection:

Foo[] foos = x.toArray(new Foo[x.size()]);

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

Two Answers

1. Answer to the asked question.

2. A simple change equals a better way!

Answer 1 - Pass the Vars Array to the __construct() in a class, you could also leave the construct empty and pass the Arrays through your functions instead.

<?php

// Create an Array with all needed Sub Arrays Example: 
// Example Sub Array 1
$content_arrays["modals"]= array();
// Example Sub Array 2
$content_arrays["js_custom"] = array();

// Create a Class
class Array_Pushing_Example_1 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Primary Contents Array as Parameter in __construct
    public function __construct($content_arrays){

        // Declare it
        $this->content_arrays = $content_arrays;

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class with the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_1($content_arrays);

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Answer 2 - A simple change however would put it inline with modern standards. Just declare your Arrays in the Class.

<?php

// Create a Class
class Array_Pushing_Example_2 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Declare Contents Array and Sub Arrays in __construct
    public function __construct(){

        // Declare them
        $this->content_arrays["modals"] = array();
        $this->content_arrays["js_custom"] = array();

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class without the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_2();

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Both options output the same information and allow a function to push and retrieve information from an Array and sub Arrays to any place in the code(Given that the data has been pushed first). The second option gives more control over how the data is used and protected. They can be used as is just modify to your needs but if they were used to extend a Controller they could share their values among any of the Classes the Controller is using. Neither method requires the use of a Global(s).

Output:

Array Custom Content Results

Modals - Count: 5

a

b

c

FOO

foo

JS Custom - Count: 9

1

2B or not 2B

3

42

5

car

house

bike

glass

Don't know if this will be everybody's answer, but after some digging, here's what we came up with.

The error is obviously caused by the fact that the listener was not accepting connections, but why would we get that error when other tests could connect fine (we could also connect no problem through sqlplus)? The key to the issue wasn't that we couldn't connect, but that it was intermittent

After some investigation, we found that there was some static data created during the class setup that would keep open connections for the life of the test class, creating new ones as it went. Now, even though all of the resources were properly released when this class went out of scope (via a finally{} block, of course), there were some cases during the run when this class would swallow up all available connections (okay, bad practice alert - this was unit test code that connected directly rather than using a pool, so the same problem could not happen in production).

The fix was to not make that class static and run in the class setup, but instead use it in the per method setUp and tearDown methods.

So if you get this error in your own apps, slap a profiler on that bad boy and see if you might have a connection leak. Hope that helps.

There is also a sample on the MSDN Code Samples gallery called Converting between RTF and HTML which allows you to convert between HTML, RTF and XAML.

A good trick is to use inner box-shadow, and let it do all the fading for you rather than applying it to the image.

It is, in principle, impossible to determine the encoding of a text file, in the general case. So no, there is no standard Python library to do that for you.

If you have more specific knowledge about the text file (e.g. that it is XML), there might be library functions.

The jQuery docs for text() says

Due to variations in the HTML parsers in different browsers, the text returned may vary in newlines and other white space.

I'd use $td.html() instead.

You could use startOf('day') method to compare just the date

Example :

var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());

dateToCompare.startOf('day').isSame(today.startOf('day'));

The following is slower than the approaches timed here, but we can compute the extra column based on the contents of more than one column, and more than two values can be computed for the extra column.

Simple example using just the "Set" column:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Example with more colours and more columns taken into account:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    elif row["Type"] == "C":
        return "blue"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C   blue

Edit (21/06/2019): Using plydata

It is also possible to use plydata to do this kind of things (this seems even slower than using assign and apply, though).

from plydata import define, if_else

Simple if_else:

df = define(df, color=if_else('Set=="Z"', '"red"', '"green"'))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Nested if_else:

df = define(df, color=if_else(
    'Set=="Z"',
    '"red"',
    if_else('Type=="C"', '"green"', '"blue"')))

print(df)                            

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B   blue
3   Y    C  green

If you define operator<< as a member function it will have a different decomposed syntax than if you used a non-member operator<<. A non-member operator<< is a binary operator, where a member operator<< is a unary operator.

// Declarations
struct MyObj;
std::ostream& operator<<(std::ostream& os, const MyObj& myObj);

struct MyObj
{
    // This is a member unary-operator, hence one argument
    MyObj& operator<<(std::ostream& os) { os << *this; return *this; }

    int value = 8;
};

// This is a non-member binary-operator, 2 arguments
std::ostream& operator<<(std::ostream& os, const MyObj& myObj)
{
    return os << myObj.value;
}

So.... how do you really call them? Operators are odd in some ways, I'll challenge you to write the operator<<(...) syntax in your head to make things make sense.

MyObj mo;

// Calling the unary operator
mo << std::cout;

// which decomposes to...
mo.operator<<(std::cout);

Or you could attempt to call the non-member binary operator:

MyObj mo;

// Calling the binary operator
std::cout << mo;

// which decomposes to...
operator<<(std::cout, mo);

You have no obligation to make these operators behave intuitively when you make them into member functions, you could define operator<<(int) to left shift some member variable if you wanted to, understand that people may be a bit caught off guard, no matter how many comments you may write.

Almost lastly, there may be times where both decompositions for an operator call are valid, you may get into trouble here and we'll defer that conversation.

Lastly, note how odd it might be to write a unary member operator that is supposed to look like a binary operator (as you can make member operators virtual..... also attempting to not devolve and run down this path....)

struct MyObj
{
    // Note that we now return the ostream
    std::ostream& operator<<(std::ostream& os) { os << *this; return os; }

    int value = 8;
};

This syntax will irritate many coders now....

MyObj mo;

mo << std::cout << "Words words words";

// this decomposes to...
mo.operator<<(std::cout) << "Words words words";

// ... or even further ...
operator<<(mo.operator<<(std::cout), "Words words words");

Note how the cout is the second argument in the chain here.... odd right?

In answer to the OP:

The PATH environment variable specifies which folders Windows will search in, in order to find such files as executable programs or DLLs. To make your Windows installation find your program, you specify the folder that the program resides in, NOT the program file itself!

So, if you want Windows to look for executables (or other desired files) in the folder:

C:\PHP

because, for example, you want to install PHP manually, and choose that folder into which to install PHP, then you add the entry:

C:\PHP

to your PATH environment variable, NOT an entry such as "C:\PHP\php.exe".

Once you've added the folder entry to your PATH environment variable, Windows will search that folder, and will execute ANY named executable file you specify, if that file happens to reside in that folder, just the same as with all the other existing PATH entries.

Before editing your PATH variable, though, protect yourself against foul ups in advance. Copy the existing value of the PATH variable to a Notepad file, and save it as a backup. If you make a mistake editing PATH, you can simply revert to the previous version with ease if you take this step.

Once you've done that, append your desired path entries to the text (again, I suggest you do this in Notepad so you can see what you're doing - the Windows 7 text box is a pain to read if you have even slight vision impairment), then paste that text into the Windows text box, and click OK.

Your PATH environment variable is a text string, consisting of a list of folder paths, each entry separated by semicolons. An example has already been given by someone else above, such as:

C:\Program Files; C:\Winnt; C:\Winnt\System32

Your exact version may vary depending upon your system.

So, to add "C:\PHP" to the above, you change it to read as follows:

C:\Program Files; C:\Winnt; C:\Winnt\System32; C:\PHP

Then you copy & paste that text into the windows dialogue box, click OK, and you should now have a new PATH variable, ready to roll. If your changes don't take effect immediately, you can always restart the computer.

Eg:

Datatable newTable =  new DataTable();

            foreach(string s1 in list)
            {
                if (s1 != string.Empty) {
                    dvProducts.RowFilter = "(CODE like '" + serachText + "*') AND (CODE <> '" + s1 + "')";
                    foreach(DataRow dr in dvProducts.ToTable().Rows)
                    {
                       newTable.ImportRow(dr);
                    }
                }
            }
ListView1.DataSource = newTable;
ListView1.DataBind();

I was looking for an example that had default kwargs using type annotation:

def test_var_kwarg(a: str, b: str='B', c: str='', **kwargs) -> str:
     return ' '.join([a, b, c, str(kwargs)])

example:

>>> print(test_var_kwarg('A', c='okay'))
A B okay {}
>>> d = {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', c='c', b='b', **d))
a b c {'f': 'F', 'g': 'G'}
>>> print(test_var_kwarg('a', 'b', 'c'))
a b c {}

{% load static %}
<img src="{% static "my_app/example.jpg" %}" alt="My image">

in your templates, use the static template tag to build the URL for the given relative path using the configured STATICFILES_STORAGE.

If you are using pkg to package your app, you'll find useful this expression:

appDirectory = require('path').dirname(process.pkg ? process.execPath : (require.main ? require.main.filename : process.argv[0]));

• process.pkg tells if the app has been packaged by pkg.

• process.execPath holds the full path of the executable, which is /usr/bin/node or similar for direct invocations of scripts (node test.js), or the packaged app.

• require.main.filename holds the full path of the main script, but it's empty when Node runs in interactive mode.

• __dirname holds the full path of the current script, so I'm not using it (although it may be what OP asks; then better use appDirectory = process.pkg ? require('path').dirname(process.execPath) : (__dirname || require('path').dirname(process.argv[0])); noting that in interactive mode __dirname is empty.

• For interactive mode, use either process.argv[0] to get the path to the Node executable or process.cwd() to get the current directory.

Just use : echo $array[count($array) - 1];

Please add Settings under Properties for the Project and make use of them this way you have clean and easy configurable settings that can be configured as default

How To: Create a New Setting at Design Time

Update: after comments below

1. Right + Click on project
2. Add New Item
3. Under Visual C# Items -> General
4. Select Settings File

Try this one:

private String toDate() {
    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

    // Create a calendar object with today date. Calendar is in java.util pakage.
    Calendar calendar = Calendar.getInstance();

    // Move calendar to yesterday
    calendar.add(Calendar.DATE, -1);

    // Get current date of calendar which point to the yesterday now
    Date yesterday = calendar.getTime();

    return dateFormat.format(yesterday).toString();
}

Use the following Code:-

../css/main.css

Note: The "../" is shorthand for "The containing directory", or "Up one directory".

If you don't know the previous folder this will be very helpful..

My main idea is creating a tempDiv above the view which we want to scroll to. It work well without lagging in my project.

scrollToView = (element, offset) => {
    var rect = element.getBoundingClientRect();
    var targetY = rect.y + window.scrollY - offset;

    var tempDiv;
    tempDiv = document.getElementById("tempDiv");
    if (tempDiv) {
        tempDiv.style.top = targetY + "px";
    } else {
        tempDiv = document.createElement('div');
        tempDiv.id = "tempDiv";
        tempDiv.style.background = "#F00";
        tempDiv.style.width = "10px";
        tempDiv.style.height = "10px";
        tempDiv.style.position = "absolute";
        tempDiv.style.top = targetY + "px";
        document.body.appendChild(tempDiv);
    }

    tempDiv.scrollIntoView({ behavior: 'smooth', block: 'start' });
}

Example using

onContactUsClick = () => {
    this.scrollToView(document.getElementById("contact-us"), 48);
}

Hope it help

CMake is actually pretty good for this. The key part was everyone on the Windows side has to remember to run CMake before loading in the solution, and everyone on our Mac side would have to remember to run it before make.

The hardest part was as a Windows developer making sure your structural changes were in the cmakelist.txt file and not in the solution or project files as those changes would probably get lost and even if not lost would not get transferred over to the Mac side who also needed them, and the Mac guys would need to remember not to modify the make file for the same reasons.

It just requires a little thought and patience, but there will be mistakes at first. But if you are using continuous integration on both sides then these will get shook out early, and people will eventually get in the habit.

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

Short answer: classmaps are static while PSR autoloading is dynamic.

If you don't want to use classmaps, use PSR autoloading instead.

select T.TABLE_NAME, T.TABLESPACE_NAME, t.avg_row_len*t.num_rows from dba_tables t
order by T.TABLE_NAME asc

See e.g. http://www.dba-oracle.com/t_script_oracle_table_size.htm for more options

Some might encounter this error either locally or on the server:

syntax error var data = new google.visualization.DataTable(<?=$jsonTable?>);

This means that their environment does not support short tags the solution is to use this instead:

<?php echo $jsonTable; ?>

And everything should work fine!

The highly regarded Joda Time library is also worth a look. This is basis for the new date and time api that is pencilled in for Java 7. The design is neat, intuitive, well documented and avoids a lot of the clumsiness of the original java.util.Date / java.util.Calendar classes.

Joda's DateFormatter can parse a String to a Joda DateTime.

How about onblur event :

<input type="text" name="name" value="value" onblur="alert(1);"/>

An alternative to overcome this is running the change detector manually.

You first inject the ChangeDetectorRef:

constructor(private changeDetector : ChangeDetectorRef) {}

Then you call it after updating the variable that controls the *ngIf

show() {
        this.display = true;
        this.changeDetector.detectChanges();
    }

Did you check the gsl package in your system. Try with this:

ldconfig-p | grep gsl

If gsl is installed, it will display the configuration path. If it is not in the standard path /usr/lib/ then you need to do the following in bash:

export PATH=$PATH:/your/path/to/gsl-config 

If gsl is not installed, simply do

sudo apt-get install libgsl0ldbl
sudo apt-get install gsl-bin libgsl0-dev

I had a problem with the mvabund package and this fixed the error

Cheers!

I do below and check if id exist and execute function if exist.

var divIDVar = $('#divID').length;
if (divIDVar === 0){ 
    console.log('No DIV Exist'); 
} else{  
    FNCsomefunction(); 
}   

This CSS worked for me:

.form-group.required.control-label:before{
   color: red;
   content: "*";
   position: absolute;
   margin-left: -10px;
}

and this HTML:

<div class="form-group required control-label">
  <label for="emailField">Email</label>
  <input type="email" class="form-control" id="emailField" placeholder="Type Your Email Address Here" />
</div>

As mentioned earlier.

 sudo rm -rf /usr/local/lib/node_modules/npm
 brew uninstall --force node                
 brew install node

First install "Microsoft ASP.NET Web API Client" nuget package:

  PM > Install-Package Microsoft.AspNet.WebApi.Client

Then use the following function to post your data:

public static async Task<TResult> PostFormUrlEncoded<TResult>(string url, IEnumerable<KeyValuePair<string, string>> postData)
{
    using (var httpClient = new HttpClient())
    {
        using (var content = new FormUrlEncodedContent(postData))
        {
            content.Headers.Clear();
            content.Headers.Add("Content-Type", "application/x-www-form-urlencoded");

            HttpResponseMessage response = await httpClient.PostAsync(url, content);

            return await response.Content.ReadAsAsync<TResult>();
        }
    }
}

And this is how to use it:

TokenResponse tokenResponse = 
    await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData);

or

TokenResponse tokenResponse = 
    (Task.Run(async () 
        => await PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData)))
        .Result

or (not recommended)

TokenResponse tokenResponse = 
    PostFormUrlEncoded<TokenResponse>(OAuth2Url, OAuth2PostData).Result;

Using org.apache.commons.io.FileUtils:

FileUtils.writeStringToFile(new File("log.txt"), "my string", Charset.defaultCharset());

Answers provided here as which camera api to use are wrong. Or better to say they are insufficient.

Some phones (for example Samsung Galaxy S6) could be above api level 21 but still may not support Camera2 api.

CameraCharacteristics mCameraCharacteristics = mCameraManager.getCameraCharacteristics(mCameraId);
Integer level = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
if (level == null || level == CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY) {
    return false;
}

CameraManager class in Camera2Api has a method to read camera characteristics. You should check if hardware wise device is supporting Camera2 Api or not.

But there are more issues to handle if you really want to make it work for a serious application: Like, auto-flash option may not work for some devices or battery level of the phone might create a RuntimeException on Camera or phone could return an invalid camera id and etc.

So best approach is to have a fallback mechanism as for some reason Camera2 fails to start you can try Camera1 and if this fails as well you can make a call to Android to open default Camera for you.

to summarize :

import inspect
print( "".join(inspect.getsourcelines(foo)[0]))

I use explicit interface implementation most of the time. Here are the main reasons.

Refactoring is safer

When changing an interface, it's better if the compiler can check it. This is harder with implicit implementations.

Two common cases come to mind:

• Adding a function to an interface, where an existing class that implements this interface already happens to have a method with the same signature as the new one. This can lead to unexpected behavior, and has bitten me hard several times. It's difficult to "see" when debugging because that function is likely not located with the other interface methods in the file (the self-documenting issue mentioned below).

• Removing a function from an interface. Implicitly implemented methods will be suddenly dead code, but explicitly implemented methods will get caught by compile error. Even if the dead code is good to keep around, I want to be forced to review it and promote it.

It's unfortunate that C# doesn't have a keyword that forces us to mark a method as an implicit implementation, so the compiler could do the extra checks. Virtual methods don't have either of the above problems due to required use of 'override' and 'new'.

Note: for fixed or rarely-changing interfaces (typically from vendor API's), this is not a problem. For my own interfaces, though, I can't predict when/how they will change.

It's self-documenting

If I see 'public bool Execute()' in a class, it's going to take extra work to figure out that it's part of an interface. Somebody will probably have to comment it saying so, or put it in a group of other interface implementations, all under a region or grouping comment saying "implementation of ITask". Of course, that only works if the group header isn't offscreen..

Whereas: 'bool ITask.Execute()' is clear and unambiguous.

Clear separation of interface implementation

I think of interfaces as being more 'public' than public methods because they are crafted to expose just a bit of the surface area of the concrete type. They reduce the type to a capability, a behavior, a set of traits, etc. And in the implementation, I think it's useful to keep this separation.

As I am looking through a class's code, when I come across explicit interface implementations, my brain shifts into "code contract" mode. Often these implementations simply forward to other methods, but sometimes they will do extra state/param checking, conversion of incoming parameters to better match internal requirements, or even translation for versioning purposes (i.e. multiple generations of interfaces all punting down to common implementations).

(I realize that publics are also code contracts, but interfaces are much stronger, especially in an interface-driven codebase where direct use of concrete types is usually a sign of internal-only code.)

Related: Reason 2 above by Jon.

And so on

Plus the advantages already mentioned in other answers here:

• When required, as per disambiguation or needing an internal interface
• Discourages "programming to an implementation" (Reason 1 by Jon)

Problems

It's not all fun and happiness. There are some cases where I stick with implicits:

• Value types, because that will require boxing and lower perf. This isn't a strict rule, and depends on the interface and how it's intended to be used. IComparable? Implicit. IFormattable? Probably explicit.
• Trivial system interfaces that have methods that are frequently called directly (like IDisposable.Dispose).

Also, it can be a pain to do the casting when you do in fact have the concrete type and want to call an explicit interface method. I deal with this in one of two ways:

1. Add publics and have the interface methods forward to them for the implementation. Typically happens with simpler interfaces when working internally.
2. (My preferred method) Add a public IMyInterface I { get { return this; } } (which should get inlined) and call foo.I.InterfaceMethod(). If multiple interfaces that need this ability, expand the name beyond I (in my experience it's rare that I have this need).

This works from my Windows 10's cmd.exe prompt

powershell -ExecutionPolicy Bypass -Command "Import-Module C:\Users\william\ps1\TravelBook; Get-TravelBook Hawaii"

This example shows

1. how to chain multiple commands
2. how to import module with module path
3. how to run a function defined in the module
4. No need for those fancy "&".

Assuming that the length is same for each array in the second dimension, you can use

public class B {    
 public static void main(String [] main){
    int [] [] nir= new int [2] [3];
    System.out.println(nir[0].length);
 }
}

This is something I always wanted, especially while setting up test fixtures. Finally, I decided to write a simple fluent builder of my own that could build any Map implementation - https://gist.github.com/samshu/b471f5a2925fa9d9b718795d8bbdfe42#file-mapbuilder-java

    /**
     * @param mapClass Any {@link Map} implementation type. e.g., HashMap.class
     */
    public static <K, V> MapBuilder<K, V> builder(@SuppressWarnings("rawtypes") Class<? extends Map> mapClass)
            throws InstantiationException,
            IllegalAccessException {
        return new MapBuilder<K, V>(mapClass);
    }

    public MapBuilder<K, V> put(K key, V value) {
        map.put(key, value);
        return this;
    }

    public Map<K, V> build() {
        return map;
    }

If you want to always prune when you fetch, I can suggest to use Aliases.

Just type git config -e to open your editor and change the configuration for a specific project and add a section like

[alias]
pfetch = fetch --prune   

the when you fetch with git pfetch the prune will be done automatically.

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());

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

Bandwidth limits

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

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

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

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

It could be a solution:

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

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

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

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

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

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

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

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

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

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

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

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

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

My solution:

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

Traffic limits DROPBOX

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

Dropbox Basic (free) accounts:

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

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

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

If you want your variables to be valid for all tests, you can have an application.properties file in your test resources directory (by default: src/test/resources) which will look something like this:

MYPROPERTY=foo

This will then be loaded and used unless you have definitions via @TestPropertySource or a similar method - the exact order in which properties are loaded can be found in the Spring documentation chapter 24. Externalized Configuration.

The attributes property contains them all:

$(this).each(function() {
  $.each(this.attributes, function() {
    // this.attributes is not a plain object, but an array
    // of attribute nodes, which contain both the name and value
    if(this.specified) {
      console.log(this.name, this.value);
    }
  });
});

What you can also do is extending .attr so that you can call it like .attr() to get a plain object of all attributes:

(function(old) {
  $.fn.attr = function() {
    if(arguments.length === 0) {
      if(this.length === 0) {
        return null;
      }

      var obj = {};
      $.each(this[0].attributes, function() {
        if(this.specified) {
          obj[this.name] = this.value;
        }
      });
      return obj;
    }

    return old.apply(this, arguments);
  };
})($.fn.attr);

Usage:

var $div = $("<div data-a='1' id='b'>");
$div.attr();  // { "data-a": "1", "id": "b" }

If() is the closest equivalent but beware of implicit conversions going on if you have set "Option Strict off"

For example, if your not careful you may be tempted to try something like:

Dim foo As Integer? = If(someTrueExpression, Nothing, 2)

Will give "foo" a value of 0!

I think the '?' operator equivalent in C# would instead fail compilation

If you don't want the $.ajax() function to return immediately, set the async option to false:

$(".my_link").click(
    function(){
    $.ajax({
        url: $(this).attr('href'),
        type: 'GET',
        async: false,
        cache: false,
        timeout: 30000,
        fail: function(){
            return true;
        },
        done: function(msg){ 
            if (parseFloat(msg)){
                return false;
            } else {
                return true;
            }
        }
    });
});

But, I would note that this would be counter to the point of AJAX. Also, you should be handling the response in the fail and done functions. Those functions will only be called when the response is received from the server.

You can use goto, return, or perhaps call abort (), exit () etc.

If you aren't on java 7, you can extract your exception handling to a method - that way you can at least minimize duplication

try {
   // try something
}
catch(ExtendsRuntimeException e) { handleError(e); }
catch(Exception e) { handleError(e); }

The issue here is your version of AngularJS; ng-attr is not working due to the fact that it was introduced in version 1.1.4. I am unsure as to why title="{{product.shortDesc}}" isn't working for you, but I imagine it is for similar reasons (old Angular version). I tested this on 1.2.9 and it is working for me.

As for the other answers here, this is NOT among the few use cases for ng-attr! This is a simple double-curly-bracket situation:

<a title="{{product.shortDesc}}" ng-bind="product.shortDesc" />

I was getting this exception when debugging in PyCharm, given that no breakpoint was being hit. To prevent it, I added a breakpoint just after the with block, and then it stopped happening.

The lock accessed is on the object, not on the method. Which variables are accessed within the method is irrelevant.

Adding "synchronized" to the method means the thread running the code must acquire the lock on the object before proceeding. Adding "static synchronized" means the thread running the code must acquire the lock on the class object before proceeding. Alternatively you can wrap code in a block like this:

public void addA() {
    synchronized(this) {
        a++;
    }
}

so that you can specify the object whose lock must be acquired.

If you want to avoid locking on the containing object you can choose between:

• using synchronized blocks that specify different locks
• making a and b atomic (using java.util.concurrent.atomic)

For my application, I use a HorizontalScrollView containing LinearLayout inside, which has orientation set to horizontal. In order to add images inside, I create ImageViews inside the activity and add them to my LinearLayout. For example:

<HorizontalScrollView 
        android:id="@+id/photo_scroll"
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:scrollbars="horizontal"
        android:visibility="gone">

        <LinearLayout 
            android:id="@+id/imageview_holder"
            android:layout_width="wrap_content"
            android:orientation="horizontal"
            android:layout_height="match_parent">

        </LinearLayout>
    </HorizontalScrollView>

An this works perfectly fine for me. In the activity all I have to do is something like the code below:

LinearLayout imgViewHolder = findViewById(R.id.imageview_holder);
ImageView img1 = new ImageView(getApplicationContext());
//set bitmap
//set img1 layout params
imgViewHolder.add(img1);
ImageView img2 = new ImageView(getApplicationContext());
//set bitmap
//set img2 layout params
imgViewHolder.add(img2); 

As I said that works for me, and I hope it helps somebody looking to achieve this as well.

A slightly faster option than using the already mentioned use of the Join() method is the Concat() method. It doesn't require an empty delimiter parameter as Join() does. Example:

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";

string result = String.Concat(test);

hence it is likely faster.

tl;dr

• Use modern java.time classes as much as possible, rather than the terrible legacy classes.
• Always specify your desired/expected time zone or offset-from-UTC rather than rely implicitly on JVM’s current default.

Example code (without exception-handling):

XMLGregorianCalendar xgc = 
    DatatypeFactory                           // Data-type converter.
    .newInstance()                            // Instantiate a converter object.
    .newXMLGregorianCalendar(                 // Converter going from `GregorianCalendar` to `XMLGregorianCalendar`.
        GregorianCalendar.from(               // Convert from modern `ZonedDateTime` class to legacy `GregorianCalendar` class.
            LocalDate                         // Modern class for representing a date-only, without time-of-day and without time zone.
            .parse( "2014-01-07" )            // Parsing strings in standard ISO 8601 format is handled by default, with no need for custom formatting pattern. 
            .atStartOfDay( ZoneOffset.UTC )   // Determine the first moment of the day as seen in UTC. Returns a `ZonedDateTime` object.
        )                                     // Returns a `GregorianCalendar` object.
    )                                         // Returns a `XMLGregorianCalendar` object.
;

Parsing date-only input string into an object of XMLGregorianCalendar class

Avoid the terrible legacy date-time classes whenever possible, such as XMLGregorianCalendar, GregorianCalendar, Calendar, and Date. Use only modern java.time classes.

When presented with a string such as "2014-01-07", parse as a LocalDate.

LocalDate.parse( "2014-01-07" )

To get a date with time-of-day, assuming you want the first moment of the day, specify a time zone. Let java.time determine the first moment of the day, as it is not always 00:00:00.0 in some zones on some dates.

LocalDate.parse( "2014-01-07" )
         .atStartOfDay( ZoneId.of( "America/Montreal" ) )

This returns a ZonedDateTime object.

ZonedDateTime zdt = 
        LocalDate
        .parse( "2014-01-07" )
        .atStartOfDay( ZoneId.of( "America/Montreal" ) )
;

zdt.toString() = 2014-01-07T00:00-05:00[America/Montreal]

But apparently, you want the start-of-day as seen in UTC (an offset of zero hours-minutes-seconds). So we specify ZoneOffset.UTC constant as our ZoneId argument.

ZonedDateTime zdt = 
        LocalDate
        .parse( "2014-01-07" )
        .atStartOfDay( ZoneOffset.UTC )
;

zdt.toString() = 2014-01-07T00:00Z

The Z on the end means UTC (an offset of zero), and is pronounced “Zulu”.

If you must work with legacy classes, convert to GregorianCalendar, a subclass of Calendar.

GregorianCalendar gc = GregorianCalendar.from( zdt ) ;

gc.toString() = java.util.GregorianCalendar[time=1389052800000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],firstDayOfWeek=2,minimalDaysInFirstWeek=4,ERA=1,YEAR=2014,MONTH=0,WEEK_OF_YEAR=2,WEEK_OF_MONTH=2,DAY_OF_MONTH=7,DAY_OF_YEAR=7,DAY_OF_WEEK=3,DAY_OF_WEEK_IN_MONTH=1,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=0,DST_OFFSET=0]

Apparently, you really need an object of the legacy class XMLGregorianCalendar. If the calling code cannot be updated to use java.time, convert.

XMLGregorianCalendar xgc = 
        DatatypeFactory
        .newInstance()
        .newXMLGregorianCalendar( gc ) 
;

Actually, that code requires a try-catch.

try
{
    XMLGregorianCalendar xgc =
            DatatypeFactory
                    .newInstance()
                    .newXMLGregorianCalendar( gc );
}
catch ( DatatypeConfigurationException e )
{
    e.printStackTrace();
}

xgc = 2014-01-07T00:00:00.000Z

Putting that all together, with appropriate exception-handling.

// Given an input string such as "2014-01-07", return a `XMLGregorianCalendar` object
// representing first moment of the day on that date as seen in UTC. 
static public XMLGregorianCalendar getXMLGregorianCalendar ( String input )
{
    Objects.requireNonNull( input );
    if( input.isBlank() ) { throw new IllegalArgumentException( "Received empty/blank input string for date argument. Message # 11818896-7412-49ba-8f8f-9b3053690c5d." ) ; }
    XMLGregorianCalendar xgc = null;
    ZonedDateTime zdt = null;

    try
    {
        zdt =
                LocalDate
                        .parse( input )
                        .atStartOfDay( ZoneOffset.UTC );
    }
    catch ( DateTimeParseException e )
    {
        throw new IllegalArgumentException( "Faulty input string for date does not comply with standard ISO 8601 format. Message # 568db0ef-d6bf-41c9-8228-cc3516558e68." );
    }

    GregorianCalendar gc = GregorianCalendar.from( zdt );
    try
    {
        xgc =
                DatatypeFactory
                        .newInstance()
                        .newXMLGregorianCalendar( gc );
    }
    catch ( DatatypeConfigurationException e )
    {
        e.printStackTrace();
    }

    Objects.requireNonNull( xgc );
    return xgc ;
}

Usage.

String input = "2014-01-07";
XMLGregorianCalendar xgc = App.getXMLGregorianCalendar( input );

Dump to console.

System.out.println( "xgc = " + xgc );

xgc = 2014-01-07T00:00:00.000Z

Modern date-time classes versus legacy

Date-time != String

Do not conflate a date-time value with its textual representation. We parse strings to get a date-time object, and we ask the date-time object to generate a string to represent its value. The date-time object has no ‘format’, only strings have a format.

So shift your thinking into two separate modes: model and presentation. Determine the date-value you have in mind, applying appropriate time zone, as the model. When you need to display that value, generate a string in a particular format as expected by the user.

Avoid legacy date-time classes

The Question and other Answers all use old troublesome date-time classes now supplanted by the java.time classes.

ISO 8601

Your input string "2014-01-07" is in standard ISO 8601 format.

The T in the middle separates date portion from time portion.

The Z on the end is short for Zulu and means UTC.

Fortunately, the java.time classes use the ISO 8601 formats by default when parsing/generating strings. So no need to specify a formatting pattern.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate ld = LocalDate.parse( "2014-01-07" ) ;

ld.toString(): 2014-01-07

Start of day ZonedDateTime

If you want to see the first moment of that day, specify a ZoneId time zone to get a moment on the timeline, a ZonedDateTime. The time zone is crucial because the date varies around the globe by zone. A few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

Never assume the day begins at 00:00:00. Anomalies such as Daylight Saving Time (DST) means the day may begin at another time-of-day such as 01:00:00. Let java.time determine the first moment.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ld.atStartOfDay( z ) ;

zdt.toString(): 2014-01-07T00:00:00Z

For your desired format, generate a string using the predefined formatter DateTimeFormatter.ISO_LOCAL_DATE_TIME and then replace the T in the middle with a SPACE.

String output = zdt.format( DateTimeFormatter.ISO_LOCAL_DATE_TIME )
                   .replace( "T" , " " ) ; 

2014-01-07 00:00:00

About java.time

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

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

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

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

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

An error was encountered while running (Domain = LaunchServicesError, Code = 0)

Usually this indicates that installd returned an error during the install process (bad resources or similar).

Unfortunately, Xcode does not display the actual underlying error (feel free to file dupes of this known bug).

You should check ~/Library/Logs/CoreSimulator/CoreSimulator.log which will log the underlying error for you.

the sh shell produces this error messages, not bash

I prefer to use

#define FALSE (0!=0) 
#define TRUE  (0==0)

or directly in the code

if (flag == (0==0)) { ... }

The compiler will take care of that. I use a lot of languages and having to remember that FALSE is 0 bothers me a lot; but if I have to, I usually think about that string loop

do { ... } while (*ptr);

and that leads me to see that FALSE is 0

What does the “at” (@) symbol do in Python?

@ symbol is a syntactic sugar python provides to utilize decorator,
to paraphrase the question, It's exactly about what does decorator do in Python?

Put it simple decorator allow you to modify a given function's definition without touch its innermost (it's closure).
It's the most case when you import wonderful package from third party. You can visualize it, you can use it, but you cannot touch its innermost and its heart.

Here is a quick example,
suppose I define a read_a_book function on Ipython

In [9]: def read_a_book():
   ...:     return "I am reading the book: "
   ...: 
In [10]: read_a_book()
Out[10]: 'I am reading the book: '

You see, I forgot to add a name to it.
How to solve such a problem? Of course, I could re-define the function as:

def read_a_book():
    return "I am reading the book: 'Python Cookbook'"

Nevertheless, what if I'm not allowed to manipulate the original function, or if there are thousands of such function to be handled.

Solve the problem by thinking different and define a new_function

def add_a_book(func):
    def wrapper():
        return func() + "Python Cookbook"
    return wrapper

Then employ it.

In [14]: read_a_book = add_a_book(read_a_book)
In [15]: read_a_book()
Out[15]: 'I am reading the book: Python Cookbook'

Tada, you see, I amended read_a_book without touching it inner closure. Nothing stops me equipped with decorator.

What's about @

@add_a_book
def read_a_book():
    return "I am reading the book: "
In [17]: read_a_book()
Out[17]: 'I am reading the book: Python Cookbook'

@add_a_book is a fancy and handy way to say read_a_book = add_a_book(read_a_book), it's a syntactic sugar, there's nothing more fancier about it.

In this case, as you want to change the src of the first value of your element, you have no need to build up a function. You can change this right in the element:

<a href='#' onclick='this.firstChild.src="../template/save.png"')'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

You have several ways to do this. You can also create a function to automatize the process:

function changeSrc(p, t) { /* where p: Parent, t: ToSource */
  p.firstChild.src = t
}

Then you can:

<a href='#' onclick='changeSrc(this, "../template/save.png");'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

Agile and SCRUM are related but distinct. Agile describes a set of guiding principles for building software through iterative development. Agile principles are best described in the Agile Manifesto. SCRUM is a specific set of rules to follow when practicing agile software development.

In Log4j2, the "extras" lib is not mandatory any more. Also the configuration format has changed.

An example is provided in the Apache documentation

property.filename = /foo/bar/test.log

appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${filename}
appender.rolling.filePattern = /foo/bar/rolling/test1-%d{MM-dd-yy-HH-mm-ss}-%i.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d %p %C{1.} [%t] %m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 2
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 5


logger.rolling.name = com.example.my.class
logger.rolling.level = debug
logger.rolling.additivity = false
logger.rolling.appenderRef.rolling.ref = RollingFile

Use numpy.array to use shape attribute.

>>> import numpy as np
>>> X = np.array([
...     [[-9.035250067710876], [7.453250169754028], [33.34074878692627]],
...     [[-6.63700008392334], [5.132999956607819], [31.66075038909912]],
...     [[-5.1272499561309814], [8.251499891281128], [30.925999641418457]]
... ])
>>> X.shape
(3L, 3L, 1L)

NOTE X.shape returns 3-items tuple for the given array; [n, T] = X.shape raises ValueError.

*** your project in eclipse. Sometime there are linkage problems. This solved my problem

As a complement to Groky's response (which is actually the best response by far in my perspective) we could also mention the ApplicationContext class, which allows also (as it's shown in the article's sample) the ability to open two (or even more) Forms on application startup, and control the application lifetime with all of them.

For this problem the best solution I use is to have a CLR function in Sql Server 2005 that uses one of DateTime.Parse or ParseExact function to return the DateTime value with a specified format.

subprocess.Popen takes a list of arguments:

from subprocess import Popen, PIPE

process = Popen(['swfdump', '/tmp/filename.swf', '-d'], stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

There's even a section of the documentation devoted to helping users migrate from os.popen to subprocess.

If john were an optional var (declared thusly)

var john: Person?

then it would be possible for john to have no value (in ObjC parlance, nil value)

The exclamation point basically tells the compiler "I know this has a value, you don't need to test for it". If you didn't want to use it, you could conditionally test for it:

if let otherPerson = john {
    otherPerson.apartment = number73
}

The interior of this will only evaluate if john has a value.

I just want to expand on queen3's suggestion, applying the following does the trick:

editoptions: { 
              dataInit: function(element) { 
                          $(element).attr("readonly", "readonly"); 
                        } 
             }

Scenario #1:

• Field must be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
        {  name:'providerUserId',
               index:'providerUserId', 
               width:100,editable:true, 
               editrules:{required:true}, 
               editoptions:{ 
                            dataInit: function(element) { 
                                  jq(element).attr("readonly", "readonly"); 
                             } 
                           }
            },
],

The providerUserId is visible in the grid and visible when editing the form. But you cannot edit the contents.

Scenario #2:

• Field must not be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
           {name:'providerUserId',
            index:'providerUserId', 
            width:100,editable:true, 
            editrules:{
                         required:true, 
                         edithidden:true
                      },
            hidden:true, 
            editoptions:{ 
                  dataInit: function(element) {                     
                             jq(element).attr("readonly", "readonly"); 
                          } 
                     }
         },
        ]

Notice in both instances I'm using jq to reference jquery, instead of the usual $. In my HTML I have the following script to modify the variable used by jQuery:

<script type="text/javascript">
    var jq = jQuery.noConflict();
</script>

The code

my_list = [(1, 2), (3, 4), (5, 6)]
for t in my_list:
    print t

prints

(1, 2)
(3, 4)
(5, 6)

The loop iterates over my_list, and assigns the elements of my_list to t one after the other. The elements of my_list happen to be tuples, so t will always be a tuple. To access the first element of the tuple t, use t[0]:

for t in my_list:
    print t[0]

To access the first element of the tuple at the given index i in the list, you can use

print my_list[i][0]

I created an extension to show all the annotations using some code from here and there in swift. This will not show all annotations if they can't be shown even at maximum zoom level.

import MapKit

extension MKMapView {
    func fitAllAnnotations() {
        var zoomRect = MKMapRectNull;
        for annotation in annotations {
            let annotationPoint = MKMapPointForCoordinate(annotation.coordinate)
            let pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);
            zoomRect = MKMapRectUnion(zoomRect, pointRect);
        }
        setVisibleMapRect(zoomRect, edgePadding: UIEdgeInsets(top: 50, left: 50, bottom: 50, right: 50), animated: true)
    }
}

This also happens when setting a foreign key to parent.id to child.column if the child.column has a value of 0 already and no parent.id value is 0

You would need to ensure that each child.column is NULL or has value that exists in parent.id

And now that I read the statement nos wrote, that's what he is validating.
