Regarding this part:

When I convert it to UTF-8 without bom and close file, the file is again ANSI when I reopen.

The easiest solution is to avoid the problem entirely by properly configuring Notepad++.

Try Settings -> Preferences -> New document -> Encoding -> choose UTF-8 without BOM, and check Apply to opened ANSI files.

That way all the opened ANSI files will be treated as UTF-8 without BOM.

For explanation what's going on, read the comments below this answer.

To fully learn about Unicode and UTF-8, read this excellent article from Joel Spolsky.

in your dispatcher servlet context xml, you have to add a propertie "<property name="contentType" value="text/html;charset=UTF-8" />" on your viewResolver bean. we are using freemarker for views.

it looks something like this:

<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
       ...
       <property name="contentType" value="text/html;charset=UTF-8" />
       ...
</bean>

The existing answers are a little too verbose so I created this smaller, auto-matching version.

function prefered_language(array $available_languages, $http_accept_language) {

    $available_languages = array_flip($available_languages);

    $langs;
    preg_match_all('~([\w-]+)(?:[^,\d]+([\d.]+))?~', strtolower($http_accept_language), $matches, PREG_SET_ORDER);
    foreach($matches as $match) {

        list($a, $b) = explode('-', $match[1]) + array('', '');
        $value = isset($match[2]) ? (float) $match[2] : 1.0;

        if(isset($available_languages[$match[1]])) {
            $langs[$match[1]] = $value;
            continue;
        }

        if(isset($available_languages[$a])) {
            $langs[$a] = $value - 0.1;
        }

    }
    arsort($langs);

    return $langs;
}

And the sample usage:

//$_SERVER["HTTP_ACCEPT_LANGUAGE"] = 'en-us,en;q=0.8,es-cl;q=0.5,zh-cn;q=0.3';

// Languages we support
$available_languages = array("en", "zh-cn", "es");

$langs = prefered_language($available_languages, $_SERVER["HTTP_ACCEPT_LANGUAGE"]);

/* Result
Array
(
    [en] => 0.8
    [es] => 0.4
    [zh-cn] => 0.3
)*/

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

I used http://codingbat.com/ . A great website that not only takes one answer, like Project Euler, but also checks your code for more robustness by running it through multiple tests. It asks for much broader code than Project Euler, but its also much simpler than most Euler problems. It also has progress graphs which are pretty cool.

From 2018:

Go to Settings -> Basic -> App Secret (type your password and you're ready to go).

You can use this to fill zeroes in a Mat object already containing data:

image1 = Scalar::all(0);

For eg, if you use it this way:

Mat image,image1;
image = imread("IMG_20160107_185956.jpg", CV_LOAD_IMAGE_COLOR);   // Read the file

if(! image.data )                              // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}
cvtColor(image,image1,CV_BGR2GRAY);
image1 = Scalar::all(0);

It will work fine. But you cannot use this for uninitialised Mat. For that you can go for other options mentioned in above answers, like

Mat drawing = Mat::zeros( image.size(), CV_8UC3 );

Adding .dockerignore works for me. One additional point Those who are trying this solution on Windows , windows will not let you create .dockerignore file (as it doesn't by default allows creating file starting with .)

To create such file starting with . on Windows, include an ending dot also, like : .dockerignore. and hit enter ( provided you have enabled view extension options from folder options )

Regular expressions to the rescue:

import re
re.sub(r'\W+', '', your_string)

By Python definition '\W == [^a-zA-Z0-9_], which excludes all numbers, letters and _

changed = (evt) => {    
this.isChecked = evt.target.checked;
}

<input type="checkbox" [checked]="checkbox" (change)="changed($event)" id="no"/>

Additional thoughts :

Ramdisk - setting the temp drive MySQL uses as a RAM disk, very easy to set up.

memcache - memcache server is easy to set up, use it to store the results of your queries for X amount of time.

I solved this error with clearing cache and restarting chrome. Hope they will fix it in ver 40.

If you are using pandas:

df['decimals'] = df['original_number'].mod(1)

Existing answers did not work for me i just used $('.confirm').hide(). and it worked for me.

success: function(res) {
$('.confirm').hide()
swal("Deleted!", "Successfully deleted", "success")
setTimeout(function(){
window.location = res.redirect_url;
},700);

I recommend that you use the standard packages email and smtplib together to send email. Please look at the following example (reproduced from the Python documentation). Notice that if you follow this approach, the "simple" task is indeed simple, and the more complex tasks (like attaching binary objects or sending plain/HTML multipart messages) are accomplished very rapidly.

# Import smtplib for the actual sending function
import smtplib

# Import the email modules we'll need
from email.mime.text import MIMEText

# Open a plain text file for reading.  For this example, assume that
# the text file contains only ASCII characters.
with open(textfile, 'rb') as fp:
    # Create a text/plain message
    msg = MIMEText(fp.read())

# me == the sender's email address
# you == the recipient's email address
msg['Subject'] = 'The contents of %s' % textfile
msg['From'] = me
msg['To'] = you

# Send the message via our own SMTP server, but don't include the
# envelope header.
s = smtplib.SMTP('localhost')
s.sendmail(me, [you], msg.as_string())
s.quit()

For sending email to multiple destinations, you can also follow the example in the Python documentation:

# Import smtplib for the actual sending function
import smtplib

# Here are the email package modules we'll need
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart

# Create the container (outer) email message.
msg = MIMEMultipart()
msg['Subject'] = 'Our family reunion'
# me == the sender's email address
# family = the list of all recipients' email addresses
msg['From'] = me
msg['To'] = ', '.join(family)
msg.preamble = 'Our family reunion'

# Assume we know that the image files are all in PNG format
for file in pngfiles:
    # Open the files in binary mode.  Let the MIMEImage class automatically
    # guess the specific image type.
    with open(file, 'rb') as fp:
        img = MIMEImage(fp.read())
    msg.attach(img)

# Send the email via our own SMTP server.
s = smtplib.SMTP('localhost')
s.sendmail(me, family, msg.as_string())
s.quit()

As you can see, the header To in the MIMEText object must be a string consisting of email addresses separated by commas. On the other hand, the second argument to the sendmail function must be a list of strings (each string is an email address).

So, if you have three email addresses: [email protected], [email protected], and [email protected], you can do as follows (obvious sections omitted):

to = ["[email protected]", "[email protected]", "[email protected]"]
msg['To'] = ",".join(to)
s.sendmail(me, to, msg.as_string())

the ",".join(to) part makes a single string out of the list, separated by commas.

From your questions I gather that you have not gone through the Python tutorial - it is a MUST if you want to get anywhere in Python - the documentation is mostly excellent for the standard library.

In my opinion the best solution is:

JAVA SOLUTION

Create simple interface :

public interface IOnBackPressed {
    /**
     * If you return true the back press will not be taken into account, otherwise the activity will act naturally
     * @return true if your processing has priority if not false
     */
    boolean onBackPressed();
}

And in your Activity

public class MyActivity extends Activity {
    @Override public void onBackPressed() {
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.main_container);
       if (!(fragment instanceof IOnBackPressed) || !((IOnBackPressed) fragment).onBackPressed()) {
          super.onBackPressed();
       }
    } ...
}

Finally in your Fragment:

public class MyFragment extends Fragment implements IOnBackPressed{
   @Override
   public boolean onBackPressed() {
       if (myCondition) {
            //action not popBackStack
            return true; 
        } else {
            return false;
        }
    }
}

KOTLIN SOLUTION

1 - Create Interface

interface IOnBackPressed {
    fun onBackPressed(): Boolean
}

2 - Prepare your Activity

class MyActivity : AppCompatActivity() {
    override fun onBackPressed() {
        val fragment =
            this.supportFragmentManager.findFragmentById(R.id.main_container)
        (fragment as? IOnBackPressed)?.onBackPressed()?.not()?.let {
            super.onBackPressed()
        }
    }
}

3 - Implement in your target Fragment

class MyFragment : Fragment(), IOnBackPressed {
    override fun onBackPressed(): Boolean {
        return if (myCondition) {
            //action not popBackStack
            true
        } else {
            false
        }
    }
}

Solution in Swift 3:

button.setTitleColor(UIColor.red, for: .normal)

This will set the title color of button.

Detecting iOS (both <12, and 13+)

Community wiki, as edit queue says it is full and all other answers are currently outdated or incomplete.

const iOS_1to12 = /iPad|iPhone|iPod/.test(navigator.platform);

const iOS13_iPad = (navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1));

const iOS1to12quirk = function() {
  var audio = new Audio(); // temporary Audio object
  audio.volume = 0.5; // has no effect on iOS <= 12
  return audio.volume === 1;
};

const isIOS = !window.MSStream && (iOS_1to12 || iOS13_iPad || iOS1to12quirk());

You can use anonymous types for example:

  var empData = from res in _db.EMPLOYEEs
                where res.EMAIL == givenInfo || res.USER_NAME == givenInfo
                select new { res.EMAIL, res.USER_NAME };

I was facing the same issue but it was not a permission issue.

When you are doing git clone it will create try to create replica of the respository structure.

When its trying to create the folder/directory with same name and path in your local os process is not allowing to do so and hence the error. There was "background" java process running in Task-manager which was accessing the resource of the directory(folder) and hence it was showing as permission denied for git operations. I have killed those process and that solved my problem. Cheers!!

You can also test them as a couple.

if (i,ii)==(5,10):
    print "i is 5 and ii is 10"

Even it is not a good way of doing what you want try this hint: var url = MUST BE A NUMER FIRST

function nextImage (){
url = url + 1;  
location.href='http://mywebsite.com/' + url+'.html';
}

Try this one:

Sub clear_sht
  Dim sht As Worksheet
  Set sht = Worksheets(GENERATOR_SHT_NAME)
  col_cnt = sht.UsedRange.Columns.count
  If col_cnt = 0 Then
    col_cnt = 1
  End If

  sht.Range(sht.Cells(1, 1), sht.Cells(sht.UsedRange.Rows.count, col_cnt)).Clear
End Sub

If you are using NUnit, take a look at this post. Basically you'll need to have your app.config in the same directory as your .nunit file.

Your way can't work for two reasons.

You need to use set /p text= for setting the variable with user input.
The other problem is the pipe.
A pipe starts two asynchronous cmd.exe instances and after finishing the job both instances are closed.

That's the cause why it seems that the variables are not set, but a small example shows that they are set but the result is lost later.

set myVar=origin
echo Hello | (set /p myVar= & set myVar)
set myVar

Outputs

Hello
origin

Alternatives: You can use the FOR loop to get values into variables or also temp files.

for /f "delims=" %%A in ('echo hello') do set "var=%%A"
echo %var%

or

>output.tmp echo Hello
>>output.tmp echo world

<output.tmp (
  set /p line1=
  set /p line2=
)
echo %line1%
echo %line2%

Alternative with a macro:

You can use a batch macro, this is a bit like the bash equivalent

@echo off

REM *** Get version string 
%$set% versionString="ver"
echo The version is %versionString[0]%

REM *** Get all drive letters
`%$set% driveLetters="wmic logicaldisk get name /value | findstr "Name""
call :ShowVariable driveLetters

The definition of the macro can be found at
SO:Assign output of a program to a variable using a MS batch file

I too have the same issue on Ubuntu, I created the .gitignore from the terminal and it works for me

touch .gitignore

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py
0:00:00.028000
0:00:02.461000

I've seen a web filtering application which does porn image filtering, sorry I can't remember the name. It was pretty prone to false positives however most of the time it was working.

I think main trick is detecting "too much skin on the picture :)

As a simple one line expression recommend this,

^([a-zA-z0-9/\\''(),-\s]{2,255})$

I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.

public List<User> getUser(int userId) {
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = createPreparedStatement(con, userId); 
         ResultSet rs = ps.executeQuery()) {

         // process the resultset here, all resources will be cleaned up

    } catch (SQLException e) {
        e.printStackTrace();
    }
}

private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    PreparedStatement ps = con.prepareStatement(sql);
    ps.setInt(1, userId);
    return ps;
}

R has multiple ways of represeting time series. Since you're working with daily prices of stocks, you may wish to consider that financial markets are closed on weekends and business holidays so that trading days and calendar days are not the same. However, you may need to work with your times series in terms of both trading days and calendar days. For example, daily returns are calculated from sequential daily closing prices regardless of whether a weekend intervenes. But you may also want to do calendar-based reporting such as weekly price summaries. For these reasons the xts package, an extension of zoo, is commonly used with financial data in R. An example of how it could be used with your data follows.

Assuming the data shown in your example is in the dataframe df

  library(xts)
  stocks <- xts(df[,-1], order.by=as.Date(df[,1], "%m/%d/%Y"))
#
#  daily returns
#
   returns <- diff(stocks, arithmetic=FALSE ) - 1
#
#  weekly open, high, low, close reports
#
   to.weekly(stocks$Hero_close, name="Hero")

which gives the output

           Hero.Open Hero.High Hero.Low Hero.Close
2013-03-15    1669.1   1684.45   1669.1    1684.45
2013-03-22    1690.5   1690.50   1623.3    1659.60
2013-03-28    1617.7   1617.70   1542.0    1542.00

You can do like that In Kotlin If you need kotlin code in the future

val myUri = getImageUri(applicationContext, myBitmap!!)
val finalFile = File(getRealPathFromURI(myUri))

fun getImageUri(inContext: Context, inImage: Bitmap): Uri {
    val bytes = ByteArrayOutputStream()
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes)
    val path = MediaStore.Images.Media.insertImage(inContext.contentResolver, inImage, "Title", null)
    return Uri.parse(path)
}

fun getRealPathFromURI(uri: Uri): String {
    val cursor = contentResolver.query(uri, null, null, null, null)
    cursor!!.moveToFirst()
    val idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)
    return cursor.getString(idx)
}

I had the same issue. The problem ended up being the path to the image file. Make sure the image path is relative to the location of the CSS file instead of the HTML.

I used TextUtils for this:

if (TextUtils.isEmpty(UsernameInfo.getText())) {
    validationError = true;
    validationErrorMessage.append(getResources().getString(R.string.error_blank_username));
}

This is perfect code but it cannot add a new row:

dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;

But this code can insert a new row:

var index = this.dataGridView1.Rows.Add();
this.dataGridView1.Rows[index].Cells[1].Value = "1";
this.dataGridView1.Rows[index].Cells[2].Value = "Baqar";

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

This can be done with MySQL, although it's highly unintuitive:

CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
  DECLARE a,b INT;
  DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
  SET b = 1;
  OPEN cur_1;
  REPEAT
    FETCH cur_1 INTO a;
    UNTIL b = 1
  END REPEAT;
  CLOSE cur_1;
  SET return_val = a;
END;//

Check out this guide: mysql-storedprocedures.pdf

I have used this way and Its a best forever. In this code null also handled

SELECT Title,
FirstName,
lastName, 
ISNULL(Title,'') + ' ' + ISNULL(FirstName,'') + ' ' + ISNULL(LastName,'') as FullName 
FROM Customer

Try this...

As well as using Package manager console to get nuget to update the project with Install-Package Microsoft.AspNet.WebApi.WebHost for missing GlobalConfiguration,

I needed Install-Package Microsoft.AspNet.WebApi.SelfHost for missing using System.Web.Http;

As far I can understand the original problem, you added commits to local master by mistake and did not push that changes yet. Now you want to cancel your changes and hope to delete your local changes and to create a new master branch from the remote one.

You can just reset your changes and reload master from remote server:

git reset --hard origin/master

One you convert your image to gray-scale you cannot got back. You have gone from three channel to one, when you try to go back all three numbers will be the same. So the short answer is no you cannot go back. The reason your backtorgb function this throwing that error is because it needs to be in the format:

CvtColor(input, output, CV_GRAY2BGR)

OpenCV use BGR not RGB, so if you fix the ordering it should work, though your image will still be gray.

Just make sure to multiply by the right factor:

Micro: multiply by 1000000 (which is 10 power 6)

Milli: multiply by 1000 (which is 10 power 3)

This is what it should look like in Dart:

var date = new DateTime.fromMicrosecondsSinceEpoch(timestamp * 1000000);

Or

var date = new DateTime.fromMillisecondsSinceEpoch(timestamp * 1000);

This works on El Capitan with MacPorts:

$ sudo port install openssl
$ env LDFLAGS="-L/opt/local/lib" CFLAGS="-I/opt/local/include" pip install cryptography

Added content of pg_env.sh to my .bashrc:

cat /opt/PostgreSQL/10/pg_env.sh

#!/bin/sh
# The script sets environment variables helpful for PostgreSQL

export PATH=/opt/PostgreSQL/10/bin:$PATH
export PGDATA=/opt/PostgreSQL/10/data
export PGDATABASE=postgres
export PGUSER=postgres
export PGPORT=5433
export PGLOCALEDIR=/opt/PostgreSQL/10/share/locale
export MANPATH=$MANPATH:/opt/PostgreSQL/10/share/man

with addition of (as per user4653174 suggestion)

export PGPASSWORD='password'

OK, let's start to see how middleware working first, that quite answer the question, this is the source code applyMiddleWare function in Redux:

function applyMiddleware() {
  for (var _len = arguments.length, middlewares = Array(_len), _key = 0; _key < _len; _key++) {
    middlewares[_key] = arguments[_key];
  }

  return function (createStore) {
    return function (reducer, preloadedState, enhancer) {
      var store = createStore(reducer, preloadedState, enhancer);
      var _dispatch = store.dispatch;
      var chain = [];

      var middlewareAPI = {
        getState: store.getState,
        dispatch: function dispatch(action) {
          return _dispatch(action);
        }
      };
      chain = middlewares.map(function (middleware) {
        return middleware(middlewareAPI);
      });
      _dispatch = compose.apply(undefined, chain)(store.dispatch);

      return _extends({}, store, {
        dispatch: _dispatch
      });
    };
  };
}

Look at this part, see how our dispatch become a function.

  ...
  getState: store.getState,
  dispatch: function dispatch(action) {
  return _dispatch(action);
}

• Note that each middleware will be given the dispatch and getState functions as named arguments.

OK, this is how Redux-thunk as one of the most used middlewares for Redux introduce itself:

Redux Thunk middleware allows you to write action creators that return a function instead of an action. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met. The inner function receives the store methods dispatch and getState as parameters.

So as you see, it will return a function instead an action, means you can wait and call it anytime you want as it's a function...

So what the heck is thunk? That's how it's introduced in Wikipedia:

In computer programming, a thunk is a subroutine used to inject an additional calculation into another subroutine. Thunks are primarily used to delay a calculation until it is needed, or to insert operations at the beginning or end of the other subroutine. They have a variety of other applications to compiler code generation and in modular programming.

The term originated as a jocular derivative of "think".

A thunk is a function that wraps an expression to delay its evaluation.

//calculation of 1 + 2 is immediate 
//x === 3 
let x = 1 + 2;

//calculation of 1 + 2 is delayed 
//foo can be called later to perform the calculation 
//foo is a thunk! 
let foo = () => 1 + 2;

So see how easy the concept is and how it can help you manage your async actions...

That's something you can live without it, but remember in programming there are always better, neater and proper ways to do things...

Stream version, filters spaces and tabs.

Stream.of(str.split("[ \\t]")).filter(s -> s.length() > 0).collect(Collectors.joining(" "))

You can't. You can only have one slide size and one orientation per presentation.

Are you projecting the presentation or delivering it on a laptop? If so, the size is sort of irrelevant.
Regardless of the slide size, the projected/displayed image will never be longer or wider than the projector/display accepts.

In case you are interested in a jQuery soluton:

This is the HTML

<a id="button" href="#">Show/Hide</a>
<div id="item">Item</div>

This is the jQuery script

$( "#button" ).click(function() {
    $( "#item" ).toggle();
});

You can see it working here:

http://jsfiddle.net/BQUyT/

If you don't know how to use jQuery, you have to use this line to load the library:

<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>

And then use this line to start:

<script>
$(function() {
    // code to fire once the library finishes downloading.
});
</script>

So for this case the final code would be this:

<script>
$(function() {
    $( "#button" ).click(function() {
        $( "#item" ).toggle();
    });
});
</script>

Let me know if you need anything else

You can read more about jQuery here: http://jquery.com/

Use:

System.Text.Encoding.ASCII.GetString(buf);

It occurs when you don't specify the no of parameters the __init__() or any other method looking for.

For example:

class Dog:
    def __init__(self):
        print("IN INIT METHOD")

    def __unicode__(self,):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")

obj=Dog("JIMMY",1,2,3,"WOOF")

When you run the above programme, it gives you an error like that:

TypeError: __init__() takes 1 positional argument but 6 were given

How we can get rid of this thing?

Just pass the parameters, what __init__() method looking for

class Dog:
    def __init__(self, dogname, dob_d, dob_m, dob_y, dogSpeakText):
        self.name_of_dog = dogname
        self.date_of_birth = dob_d
        self.month_of_birth = dob_m
        self.year_of_birth = dob_y
        self.sound_it_make = dogSpeakText

    def __unicode__(self, ):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")


obj = Dog("JIMMY", 1, 2, 3, "WOOF")
print(id(obj))

The loop in your code is only an over-simplified example, right?

It would be better to create the PreparedStatement only once, and re-use it over and over again in the loop.

In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.

To address the situation that you want to re-use the Java-side PreparedStatement, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement for the same SQL on the same connection, it will give you the same (cached) instance.

About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.

I use this method in writing batch files for testing.

echo %userdomain%\%username%

Since you must include the password in plain text if authentication is required, I will only use it in a completely private environment where other users cannot view it or if a user seeing the password would bear no consequences.

Hope this helps someone out.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

I was having the same error message for a mistake I made: Make sure you use a correct s3 uri such as: s3://my-bucket-name/

(If my-bucket-name is at the root of your aws s3 obviously)

I insist on that because when copy pasting the s3 bucket from your browser you get something like https://s3.console.aws.amazon.com/s3/buckets/my-bucket-name/?region=my-aws-regiontab=overview

Thus I made the mistake to use s3://buckets/my-bucket-name which raises:

An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

I did a little experiment to see which of these methods

• string.startswith('hello')
• string.rfind('hello') == 0
• string.rpartition('hello')[0] == ''
• string.rindex('hello') == 0

are most efficient to return whether a certain string begins with another string.

Here is the result of one of the many test runs I've made, where each list is ordered to show the least time it took (in seconds) to parse 5 million of each of the above expressions during each iteration of the while loop I used:

I believe that it is pretty obvious from the start that the startswith method would come out the most efficient, as returning whether a string begins with the specified string is its main purpose.

What surprises me is that the seemingly impractical string.rpartition('hello')[0] == '' method always finds a way to be listed first, before the string.startswith('hello') method, every now and then. The results show that using str.partition to determine if a string starts with another string is more efficient then using both rfind and rindex.

Another thing I've noticed is that string.rindex('hello') == 0 and string.rindex('hello') == 0 have a good battle going on, each rising from fourth to third place, and dropping from third to fourth place, which makes sense, as their main purposes are the same.

Here is the code:

from time import perf_counter

string = 'hello world'
places = dict()

while True:
    start = perf_counter()
    for _ in range(5000000):
        string.startswith('hello')
    end = perf_counter()
    places['startswith'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rfind('hello') == 0
    end = perf_counter()
    places['rfind'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rpartition('hello')[0] == ''
    end = perf_counter()
    places['rpartition'] = round(end - start, 2)

    start = perf_counter()
    for _ in range(5000000):
        string.rindex('hello') == 0
    end = perf_counter()
    places['rindex'] = round(end - start, 2)
    
    print([f'{b}: {str(a).ljust(4, "4")}' for a, b in sorted(i[::-1] for i in places.items())])

One possible way to do this in just one line by using a map, simple I am checking whether a > b if it is true I am assigning c to a otherwise b

c := map[bool]int{true: a, false: b}[a > b]

However, this looks amazing but in some cases it might NOT be the perfect solution because of evaluation order. For example, if I am checking whether an object is not nil get some property out of it, look at the following code snippet which will panic in case of myObj equals nil

type MyStruct struct {
   field1 string
   field2 string 
}

var myObj *MyStruct
myObj = nil 

myField := map[bool]string{true: myObj.field1, false: "empty!"}[myObj != nil}

Because map will be created and built first before evaluating the condition so in case of myObj = nil this will simply panic.

Not to forget to mention that you can still do the conditions in just one simple line, check the following:

var c int
...
if a > b { c = a } else { c = b}

None of these solutions worked for me. I needed to know the server port while constructing a Swagger configuration bean. Using ServerProperties worked for me:

import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.ws.rs.ApplicationPath;

import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.jaxrs.listing.ApiListingResource;
import io.swagger.jaxrs.listing.SwaggerSerializers;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;

@Component
@ApplicationPath("api")
public class JerseyConfig extends ResourceConfig 
{
    @Inject
    private org.springframework.boot.autoconfigure.web.ServerProperties serverProperties;

    public JerseyConfig() 
    {
        property(org.glassfish.jersey.server.ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true);
    }

    @PostConstruct
    protected void postConstruct()
    {
        // register application endpoints
        registerAndConfigureSwaggerUi();
    }

    private void registerAndConfigureSwaggerUi()
    {
        register(ApiListingResource.class);
        register(SwaggerSerializers.class);

        final BeanConfig config = new BeanConfig();
        // set other properties
        config.setHost("localhost:" + serverProperties.getPort()); // gets server.port from application.properties file         
    }
}

This example uses Spring Boot auto configuration and JAX-RS (not Spring MVC).

C++ supplies a string class that can be used like this:

#include <string>
#include <iostream>

int main() {
    std::string Something = "Some text";
    std::cout << Something << std::endl;
}

According to a user on PHP.net site, his efforts to keep session alive failed, so he had to make a workaround.

<?php

$Lifetime = 3600;
$separator = (strstr(strtoupper(substr(PHP_OS, 0, 3)), "WIN")) ? "\\" : "/";

$DirectoryPath = dirname(__FILE__) . "{$separator}SessionData";
//in Wamp for Windows the result for $DirectoryPath
//would be C:\wamp\www\your_site\SessionData

is_dir($DirectoryPath) or mkdir($DirectoryPath, 0777);

if (ini_get("session.use_trans_sid") == true) {
    ini_set("url_rewriter.tags", "");
    ini_set("session.use_trans_sid", false);

}

ini_set("session.gc_maxlifetime", $Lifetime);
ini_set("session.gc_divisor", "1");
ini_set("session.gc_probability", "1");
ini_set("session.cookie_lifetime", "0");
ini_set("session.save_path", $DirectoryPath);
session_start();

?>

In SessionData folder it will be stored text files for holding session information, each file would be have a name similar to "sess_a_big_hash_here".

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.

You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.

Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.

So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".

That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.

SOAP:

SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.

REST:

REST is a design concept.

The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)

Flickr's REST API goes further and lets you return images as well.

JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.

var myM = angular.module('data-module');

myM.directive('myDirect',['$document', function( $document ){

    function link( scope , element , attrs ){

        element.ready( function(){

        } );

        scope.$on( '$viewContentLoaded' , function(){

            console.log(" ===> Called on View Load ") ;

        } );

    }

    return {
        link: link
    };

}] );

Above method worked for me

You could always iterate over a copy of the list, leaving you free to modify the original:

for item in list(somelist):
  ...
  somelist.remove(item)

Type hints are for maintainability and don't get interpreted by Python. In the code below, the line def add(self, ic:int) doesn't result in an error until the next return... line:

class C1:
    def __init__(self):
        self.idn = 1
    def add(self, ic: int):
        return self.idn + ic

c1 = C1()
c1.add(2)

c1.add(c1)

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<input>", line 5, in add
TypeError: unsupported operand type(s) for +: 'int' and 'C1'

I could achieve this by running:

pip install --proxy=http://user:[email protected]:3128 package==version

I'm using Python 3.7.3 inside a corporative proxy.

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

You can't initialize your testArray field this way, because the application resources still aren't ready.

Just change the code to:

package com.xtensivearts.episode.seven;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class Episode7 extends ListActivity {
    String[] mTestArray;

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create an ArrayAdapter that will contain all list items
        ArrayAdapter<String> adapter;

        mTestArray = getResources().getStringArray(R.array.testArray);    

        /* Assign the name array to that adapter and 
        also choose a simple layout for the list items */ 
        adapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_list_item_1,
            mTestArray);

        // Assign the adapter to this ListActivity
        setListAdapter(adapter);
    }
}

I should like to provide the modern answer.

You shouldn’t really want to convert a date and time from a string at one GMT offset to a string at a different GMT offset and with in a different format. Rather in your program keep an instant (a point in time) as a proper date-time object. Only when you need to give string output, format your object into the desired string.

java.time

Parsing input

    DateTimeFormatter formatter = new DateTimeFormatterBuilder()
            .append(DateTimeFormatter.ISO_LOCAL_DATE)
            .appendLiteral(' ')
            .append(DateTimeFormatter.ISO_LOCAL_TIME)
            .toFormatter();

    String dateTimeString = "2011-10-06 03:35:05";
    Instant instant = LocalDateTime.parse(dateTimeString, formatter)
            .atOffset(ZoneOffset.UTC)
            .toInstant();

For most purposes Instant is a good choice for storing a point in time. If you needed to make it explicit that the date and time came from GMT, use an OffsetDateTime instead.

Converting, formatting and printing output

    ZoneId desiredZone = ZoneId.of("Pacific/Auckland");
    Locale desiredeLocale = Locale.forLanguageTag("en-NZ");
    DateTimeFormatter desiredFormatter = DateTimeFormatter.ofPattern(
            "dd MMM uuuu HH:mm:ss OOOO", desiredeLocale);

    ZonedDateTime desiredDateTime = instant.atZone(desiredZone);
    String result = desiredDateTime.format(desiredFormatter);
    System.out.println(result);

This printed:

06 Oct 2011 16:35:05 GMT+13:00

I specified time zone Pacific/Auckland rather than the offset you mentioned, +13:00. I understood that you wanted New Zealand time, and Pacific/Auckland better tells the reader this. The time zone also takes summer time (DST) into account so you don’t need to take this into account in your own code (for most purposes).

Since Oct is in English, it’s a good idea to give the formatter an explicit locale. GMT might be localized too, but I think that it just prints GMT in all locales.

OOOO in the format patterns string is one way of printing the offset, which may be a better idea than printing the time zone abbreviation you would get from z since time zone abbreviations are often ambiguous. If you want NZDT (for New Zealand Daylight Time), just put z there instead.

Your questions

I will answer your numbered questions in relation to the modern classes in java.time.

Is possible to:

1. Set the time on an object

No, the modern classes are immutable. You need to create an object that has the desired date and time from the outset (this has a number of advantages including thread safety).

2. (Possibly) Set the TimeZone of the initial time stamp

The atZone method that I use in the code returns a ZonedDateTime with the specified time zone. Other date-time classes have a similar method, sometimes called atZoneSameInstant or other names.

3. Format the time stamp with a new TimeZone

With java.time converting to a new time zone and formatting are two distinct steps as shown.

4. Return a string with new time zone time.

Yes, convert to the desired time zone as shown and format as shown.

I found that anytime I try to set the time like this:

calendar.setTime(new Date(1317816735000L));

the local machine's TimeZone is used. Why is that?

It’s not the way you think, which goes nicely to show just a couple of the (many) design problems with the old classes.

• A Date hasn’t got a time zone. Only when you print it, its toString method grabs your local time zone and uses it for rendering the string. This is true for new Date() too. This behaviour has confused many, many programmers over the last 25 years.
• A Calender has got a time zone. It doesn’t change when you do calendar.setTime(new Date(1317816735000L));.

PHP has several libraries for XML Manipulation.

The Document Object Model (DOM) approach (which is a W3C standard and should be familiar if you've used it in other environments such as a Web Browser or Java, etc). Allows you to create documents as follows

<?php
    $doc = new DOMDocument( );
    $ele = $doc->createElement( 'Root' );
    $ele->nodeValue = 'Hello XML World';
    $doc->appendChild( $ele );
    $doc->save('MyXmlFile.xml');
?>

Even if you haven't come across the DOM before, it's worth investing some time in it as the model is used in many languages/environments.

The original question is about Bootstrap 3 and that supports IE8 and 9 so Flexbox would be the best option but it's not part of my answer due the lack of support, see http://caniuse.com/#feat=flexbox and toggle the IE box. Pretty bad, eh?

2 ways:

1. Display-table: You can muck around with turning the row into a display:table and the col- into display:table-cell. It works buuuut the limitations of tables are there, among those limitations are the push and pull and offsets won't work. Plus, I don't know where you're using this -- at what breakpoint. You should make the image full width and wrap it inside another container to put the padding on there. Also, you need to figure out the design on mobile, this is for 768px and up. When I use this, I redeclare the sizes and sometimes I stick importants on them because tables take on the width of the content inside them so having the widths declared again helps this. You will need to play around. I also use a script but you have to change the less files to use it or it won't work responsively.

I've found it true, as already mentioned, that the best performing method is to write out key/vals to a file, and then use grep/awk to retrieve them. It sounds like all sorts of unnecessary IO, but disk cache kicks in and makes it extremely efficient -- much faster than trying to store them in memory using one of the above methods (as the benchmarks show).

Here's a quick, clean method I like:

hinit() {
    rm -f /tmp/hashmap.$1
}

hput() {
    echo "$2 $3" >> /tmp/hashmap.$1
}

hget() {
    grep "^$2 " /tmp/hashmap.$1 | awk '{ print $2 };'
}

hinit capitols
hput capitols France Paris
hput capitols Netherlands Amsterdam
hput capitols Spain Madrid

echo `hget capitols France` and `hget capitols Netherlands` and `hget capitols Spain`

If you wanted to enforce single-value per key, you could also do a little grep/sed action in hput().

You can use PyPdf2s PdfMerger class.

File Concatenation

You can simply concatenate files by using the append method.

from PyPDF2 import PdfFileMerger

pdfs = ['file1.pdf', 'file2.pdf', 'file3.pdf', 'file4.pdf']

merger = PdfFileMerger()

for pdf in pdfs:
    merger.append(pdf)

merger.write("result.pdf")
merger.close()

You can pass file handles instead file paths if you want.

File Merging

If you want more fine grained control of merging there is a merge method of the PdfMerger, which allows you to specify an insertion point in the output file, meaning you can insert the pages anywhere in the file. The append method can be thought of as a merge where the insertion point is the end of the file.

e.g.

merger.merge(2, pdf)

Here we insert the whole pdf into the output but at page 2.

Page Ranges

If you wish to control which pages are appended from a particular file, you can use the pages keyword argument of append and merge, passing a tuple in the form (start, stop[, step]) (like the regular range function).

e.g.

merger.append(pdf, pages=(0, 3))    # first 3 pages
merger.append(pdf, pages=(0, 6, 2)) # pages 1,3, 5

If you specify an invalid range you will get an IndexError.

Note: also that to avoid files being left open, the PdfFileMergers close method should be called when the merged file has been written. This ensures all files are closed (input and output) in a timely manner. It's a shame that PdfFileMerger isn't implemented as a context manager, so we can use the with keyword, avoid the explicit close call and get some easy exception safety.

You might also want to look at the pdfcat script provided as part of pypdf2. You can potentially avoid the need to write code altogether.

The PyPdf2 github also includes some example code demonstrating merging.

There is no lawbreaking or outlaw standard other than common sense. If we abstract this like two people talking, the standard is the best way they can accurately understand each other in minimum words in minimum time. In our case, 'minimum words' is optimizing bandwidth for transport efficiency and 'accurately understand' is the structure for parser efficiency; which ultimately ends up with the less the data, and the common the structure; so that it can go through a pin hole and can be parsed through a common scope (at least initially).

Almost in every cases suggested, I see separate responses for 'Success' and 'Error' scenario, which is kind of ambiguity to me. If responses are different in these two cases, then why do we really need to put a 'Success' flag there? Is it not obvious that the absence of 'Error' is a 'Success'? Is it possible to have a response where 'Success' is TRUE with an 'Error' set? Or the way, 'Success' is FALSE with no 'Error' set? Just one flag is not enough? I would prefer to have the 'Error' flag only, because I believe there will be less 'Error' than 'Success'.

Also, should we really make the 'Error' a flag? What about if I want to respond with multiple validation errors? So, I find it more efficient to have an 'Error' node with each error as child to that node; where an empty (counts to zero) 'Error' node would denote a 'Success'.

Just use

del /f /q C:\Users\%username%\AppData\Local\temp

And it will work.

Note: It will delete the whole folder however, Windows will remake it as it needs.

cd C:\path\dir
svn checkout https://server/path/to/trunk/dir/dir/parent_dir--depth empty
cd C:\path\dir\parent_dir
svn update filename.log

(Edit filename.log)

svn commit -m "this is a comment."

./configure command should generate a makefile, named makefile or Makefile. if in the directory there is no this file, you should check whether the configure command execute success.

in my case, I configure the apr-util:

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config

because the --with-apr=/usr/local/apr/bin/apr-1-config, the apr did not install yet, so there configure fail, there did not generate the apr's /usr/local/apr/bin/apr-1-config.

So I install the apr, then configure the apr-util, it works.

Answer updated with ES6:

import React, { Component } from 'react';
import { Link } from 'react-router'

class NavLink extends Component {
    render() {
        let isActive = this.context.router.isActive(this.props.to, true);
        let className = isActive ? "active" : "";

        return (
            <li className={className}>
                <Link {...this.props}/>
            </li>
        );
    }
}

NavLink.contextTypes = {
    router: React.PropTypes.object
};

export default NavLink;

Then use it as described above.

If you don't need the DATETIME value in the rest of your code, it'd be more efficient, simple and secure to use an UPDATE query with a sub-select, something like

UPDATE products SET t=(SELECT f FROM products WHERE id=17) WHERE id=42;

or in case it's in the same row in a single table, just

UPDATE products SET t=f WHERE id=42;

I created the cross-platform Service Manager software a few years back so that I could start PHP and other scripting languages as system services on Windows, Mac, and Linux OSes:

https://github.com/cubiclesoft/service-manager

Service Manager is a set of precompiled binaries that install and manage a system service on the target OS using nearly identical command-line options (source code also available). Each platform does have subtle differences but the core features are mostly normalized.

If the child process dies, Service Manager automatically restarts it.

Processes that are started with Service Manager should periodically watch for two notification files to handle restart and reload requests but they don't necessarily have to do that. Service Manager will force restart the child process if it doesn't respond in a timely fashion to controlled restart/reload requests.

Just an FYI, clearer, more readable syntax IMHO

"use strict";
String.prototype.pad = function( len, c, left ) {
    var s = '',
        c = ( c || ' ' ),
        len = Math.max( len, 0 ) - this.length,
        left = ( left || false );
    while( s.length < len ) { s += c };
    return ( left ? ( s + this ) : ( this + s ) );
}
Number.prototype.pad = function( len, c, left ) {
    return String( this ).pad( len, c, left );
}
Number.prototype.lZpad = function( len ) {
    return this.pad( len, '0', true );
}

This also results in less visual and readability glitches of the results than some of the other solutions, which enforce '0' as a character; answering my questions what do I do if I want to pad other characters, or on the other direction (right padding), whilst remaining easy to type, and clear to read. Pretty sure it's also the DRY'est example, with the least code for the actual leading-zero-padding function body (as the other dependent functions are largely irrelevant to the question).

The code is available for comment via gist from this github user (original source of the code) https://gist.github.com/Lewiscowles1986/86ed44f428a376eaa67f

A note on console & script testing, numeric literals seem to need parenthesis, or a variable in order to call methods, so 2.pad(...) will cause an error, whilst (2).pad(0,'#') will not. This is the same for all numbers it seems

If you are using hash or browser history then you can do

hashHistory.push('/login');
browserHistory.push('/login');

Another way to get rid of new files that is more specific than git clean -df (it will allow you to get rid of some files not necessarily all), is to add the new files to the index first, then stash, then drop the stash.

This technique is useful when, for some reason, you can't easily delete all of the untracked files by some ordinary mechanism (like rm).

Or for multiple ignores on the next line, string the rules using commas

// eslint-disable-next-line class-methods-use-this, no-unused-vars

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.

<table border="1" width="183" style='table-layout:fixed'>
  <col width="67">
  <col width="75">
  <col width="41">
  <tr>
    <td>First Column</td>
    <td>Second Column</td>
    <td>Third Column</td>
  </tr>
  <tr>
    <td>Row 1</td>
    <td>Text</td>
    <td align="right">1</td>
  </tr>
  <tr>
    <td>Row 2</td>
    <td>Abcdefg</td>
    <td align="right">123</td>
  </tr>
  <tr>
    <td>Row 3</td>
    <td>Abcdefghijklmnop</td>
    <td align="right">123456</td>
  </tr>
</table>

I know it's old school, but give that a try, it works.

may also want to add this:

<style>
  td {overflow:hidden;}
</style>

Of course, you'd put this in a separate linked stylesheet, and not inline... wouldn't you ;)

This example code shows you how to read file in Java.

import java.io.*;

/**

 public class ReadFileExample 
 {
    public static void main(String[] args) 
    {
       System.out.println("Reading File from Java code");
       //Name of the file
       String fileName="RAILWAY.txt";
       try{

          //Create object of FileReader
          FileReader inputFile = new FileReader(fileName);

          //Instantiate the BufferedReader Class
          BufferedReader bufferReader = new BufferedReader(inputFile);

          //Variable to hold the one line data
          String line;

          // Read file line by line and print on the console
          while ((line = bufferReader.readLine()) != null)   {
            System.out.println(line);
          }
          //Close the buffer reader
          bufferReader.close();
       }catch(Exception e){
          System.out.println("Error while reading file line by line:" + e.getMessage());

  }

Oh, I found it. You use last instead of break

for my $entry (@array){
    if ($string eq "text"){
         last;
    }
}

You can use SQL Server recursive CTE

DECLARE 
    @MinDate DATE = '2020-01-01',
    @MaxDate DATE = '2020-02-01';

WITH Dates(day) AS 
(
    SELECT CAST(@MinDate as Date) as day
    UNION ALL
    SELECT CAST(DATEADD(day, 1, day) as Date) as day
    FROM Dates
    WHERE CAST(DATEADD(day, 1, day) as Date) < @MaxDate
)
SELECT* FROM dates;

In my case, log4net wasn't logging properly due to having a space in my project name. Drove me nuts why the same code worked just fine in a different project, but didn't in the new one. Spaces. A simple space.

So, beware spaces in project names. I've learned my lesson.

In android studio you may see the following folder drawable xhdpi, drawable-hdpi, drawable-mdpi and more... You can put images of different dpi in these folder accordingly and android will take care which images should be draw according to the screen density of device.

NOTE: You have to put the images with the same name.

If the statements are in the context of how CSS affects HTML then DOM element refers to an HTML element.

A simple way to do this is to call a logging function:

DEBUG = True

def log(s):
    if DEBUG:
        print s

log("hello world")

Then you can change the value of DEBUG and run your code with or without logging.

The standard logging module has a more elaborate mechanism for this.

I totally agree with the guys, it's better to use virtualenv so you can set a custom environment for every project. It ideal for maintenance because it's like a different world for every project and every update of an application you make won't interfere with other projects.

Here you can find a nutshell of virtualenv related to installation and first steps.

Variable names should be known at compile time. If you intend to populate those names dynamically at runtime you could use a List<T>

 var variables = List<Variable>();
 variables.Add(new Variable { Name = inputStr1 });
 variables.Add(new Variable { Name = inputStr2 });

here input string maybe any text or any list

One way would be to use a nested query:

SELECT count(*)
FROM (
   SELECT COUNT(Genre) AS count
   FROM movies
   GROUP BY ID
   HAVING (count = 4)
) AS x

The inner query gets all the movies that have exactly 4 genres, then outer query counts how many rows the inner query returned.

I/O is an operating system function. In many cases, the operating system won't pass typed character to a program until ENTER is pressed. This allows the user to modify the input (such as backspacing and retyping) before sending it to the program. For most purposes, this works well, presents a consistent interface to the user, and relieves the program from having to deal with this. In some cases, it's desirable for a program to get characters from keys as they are pressed.

The C library itself deals with files, and doesn't concern itself with how data gets into the input file. Therefore, there's no way in the language itself to get keys as they are pressed; instead, this is platform-specific. Since you haven't specified OS or compiler, we can't look it up for you.

Also, the standard output is normally buffered for efficiency. This is done by the C libraries, and so there is a C solution, which is to fflush(stdout); after each character written. After that, whether the characters are displayed immediately is up to the operating system, but all the OSes I'm familiar with will display the output immediately, so that's not normally a problem.

You can also try <C-x><C-l> which will repeat the last line from insert mode and brings you a completion window with all of the lines. It works almost like <C-p>

Or do the following:

...

  Integer[] integerArray = new Integer[integerList.size()];
  integerList.toArray(integerArray);

  return integerArray;

}

Replace the username and password with Integrated Security=SSPI;

So the connection string should be

<connectionStrings> 
<add name="NorthwindContex" 
   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" /> 
</connectionStrings> 

If you want emulate enum of C/C++ (base num and nexts incrementals):

enum ids {
    OPEN, CLOSE;
    //
    private static final int BASE_ORDINAL = 100;
    public int getCode() {
        return ordinal() + BASE_ORDINAL;
    }
};

public class TestEnum {
    public static void main (String... args){
        for (ids i : new ids[] { ids.OPEN, ids.CLOSE }) {
            System.out.println(i.toString() + " " + 
                i.ordinal() + " " + 
                i.getCode());
        }
    }
}

OPEN 0 100
CLOSE 1 101

Here you go:

select length('123-345-566') - length(replace('123-345-566','-',null)) 
from dual;

Technically, if the string you want to check contains only the character you want to count, the above query will return NULL; the following query will give the correct answer in all cases:

select coalesce(length('123-345-566') - length(replace('123-345-566','-',null)), length('123-345-566'), 0) 
from dual;

The final 0 in coalesce catches the case where you're counting in an empty string (i.e. NULL, because length(NULL) = NULL in ORACLE).

#include <time.h>
clock_t uptime = clock() / (CLOCKS_PER_SEC / 1000);

There are two approaches: shmget and mmap. I'll talk about mmap, since it's more modern and flexible, but you can take a look at man shmget (or this tutorial) if you'd rather use the old-style tools.

The mmap() function can be used to allocate memory buffers with highly customizable parameters to control access and permissions, and to back them with file-system storage if necessary.

The following function creates an in-memory buffer that a process can share with its children:

#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>

void* create_shared_memory(size_t size) {
  // Our memory buffer will be readable and writable:
  int protection = PROT_READ | PROT_WRITE;

  // The buffer will be shared (meaning other processes can access it), but
  // anonymous (meaning third-party processes cannot obtain an address for it),
  // so only this process and its children will be able to use it:
  int visibility = MAP_SHARED | MAP_ANONYMOUS;

  // The remaining parameters to `mmap()` are not important for this use case,
  // but the manpage for `mmap` explains their purpose.
  return mmap(NULL, size, protection, visibility, -1, 0);
}

The following is an example program that uses the function defined above to allocate a buffer. The parent process will write a message, fork, and then wait for its child to modify the buffer. Both processes can read and write the shared memory.

#include <string.h>
#include <unistd.h>

int main() {
  char parent_message[] = "hello";  // parent process will write this message
  char child_message[] = "goodbye"; // child process will then write this one

  void* shmem = create_shared_memory(128);

  memcpy(shmem, parent_message, sizeof(parent_message));

  int pid = fork();

  if (pid == 0) {
    printf("Child read: %s\n", shmem);
    memcpy(shmem, child_message, sizeof(child_message));
    printf("Child wrote: %s\n", shmem);

  } else {
    printf("Parent read: %s\n", shmem);
    sleep(1);
    printf("After 1s, parent read: %s\n", shmem);
  }
}

Here is the example I use for all of my form email inputs. This example is ASP.NET, but applies to any:

<asp:TextBox runat="server" class="form-control" placeholder="Contact's email" 
    name="contact_email" ID="contact_email" title="Contact's email (format: [email protected])" 
    type="email" TextMode="Email" validate="required:true"
    pattern="[a-zA-Z0-9!#$%&'*+\/=?^_`{|}~.-]+@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*" >
</asp:TextBox>

HTML5 still validates using the pattern when not required. Haven't found one yet that was a false positive.

This renders as the following HTML:

<input class="form-control" placeholder="Contact's email" 
    name="contact_email" id="contact_email" type="email" 
    title="Contact's email (format: [email protected])" 
    pattern="[a-zA-Z0-9!#$%&amp;'*+\/=?^_`{|}~.-]+@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*">

I suspect you can adjust your approach a little and use something along the lines of the example here:

https://www.typescriptlang.org/docs/handbook/advanced-types.html#user-defined-type-guards

function isFish(pet: Fish | Bird): pet is Fish {
  return (pet as Fish).swim !== undefined;
}

You can use defaultdict in collections.

An example from doc:

s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
d = defaultdict(list)
for k, v in s:
    d[k].append(v)

A brute force approach:

• update the .gitmodules file in the supermodule to point to the new submodule url,
• add and commit the changes to supermodule/.gitmodules,
• make a new clone of the supermodule somewhere else on your computer (making sure that the latest changes to the .gitmodules file are reflected in the clone),
• change your working directory to the new clone of the supermodule,
• run git submodule update --init path-to-submodule on the submodule,

et voilà! The submodule in the new clone of the supermodule is properly configured!

Generally, setting static field by object instance is a bad practice.

to avoid optional issues you can add synchronized definition, and set it only if private static Logger logger;

@Autowired
public synchronized void setLogger(Logger logger)
{
    if (MyClass.logger == null)
    {
        MyClass.logger = logger;
    }
}

I personally use the helper class which supports generics (Swift 3, 4.x compatible)

struct Rescale<Type : BinaryFloatingPoint> {
    typealias RescaleDomain = (lowerBound: Type, upperBound: Type)

    var fromDomain: RescaleDomain
    var toDomain: RescaleDomain

    init(from: RescaleDomain, to: RescaleDomain) {
        self.fromDomain = from
        self.toDomain = to
    }

    func interpolate(_ x: Type ) -> Type {
        return self.toDomain.lowerBound * (1 - x) + self.toDomain.upperBound * x;
    }

    func uninterpolate(_ x: Type) -> Type {
        let b = (self.fromDomain.upperBound - self.fromDomain.lowerBound) != 0 ? self.fromDomain.upperBound - self.fromDomain.lowerBound : 1 / self.fromDomain.upperBound;
        return (x - self.fromDomain.lowerBound) / b
    }

    func rescale(_ x: Type )  -> Type {
        return interpolate( uninterpolate(x) )
    }
}

Ex:

   let rescaler = Rescale<Float>(from: (-1, 1), to: (0, 100))
    
   print(rescaler.rescale(0)) // OUTPUT: 50

The main differenece is that bidirectional relationship provides navigational access in both directions, so that you can access the other side without explicit queries. Also it allows you to apply cascading options to both directions.

Note that navigational access is not always good, especially for "one-to-very-many" and "many-to-very-many" relationships. Imagine a Group that contains thousands of Users:

• How would you access them? With so many Users, you usually need to apply some filtering and/or pagination, so that you need to execute a query anyway (unless you use collection filtering, which looks like a hack for me). Some developers may tend to apply filtering in memory in such cases, which is obviously not good for performance. Note that having such a relationship can encourage this kind of developers to use it without considering performance implications.

• How would you add new Users to the Group? Fortunately, Hibernate looks at the owning side of relationship when persisting it, so you can only set User.group. However, if you want to keep objects in memory consistent, you also need to add User to Group.users. But it would make Hibernate to fetch all elements of Group.users from the database!

So, I can't agree with the recommendation from the Best Practices. You need to design bidirectional relationships carefully, considering use cases (do you need navigational access in both directions?) and possible performance implications.

If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

On terminal type mvn -v and the output will look like the image shown below

Various ways to create a branch in git from another branch:

This answer adds some additional insight, not already present in the existing answers, regarding just the title of the question itself (Create a branch in Git from another branch), but does not address the more narrow specifics of the question which already have sufficient answers here.

I'm adding this because I really needed to know how to do #1 below just now (create a new branch from a branch I do NOT have checked out), and it wasn't obvious how to do it, and Google searches led to here as a top search result. So, I'll share my findings here. This isn't touched upon well, if at all, by any other answer here.

While I'm at it, I'll also add my other most-common git branch commands I use in my regular workflow, below.

1. To create a new branch from a branch you do NOT have checked out:

Create branch2 from branch1 while you have any branch whatsoever checked out (ex: let's say you have master checked out):

git branch branch2 branch1

The general format is:

git branch <new_branch> [from_branch]

man git branch shows it as:

git branch [--track | --no-track] [-l] [-f] <branchname> [<start-point>]

2. To create a new branch from the branch you DO have checked out:

git branch new_branch

This is great for making backups before rebasing, squashing, hard resetting, etc.--before doing anything which could mess up your branch badly.

Ex: I'm on feature_branch1, and I'm about to squash 20 commits into 1 using git rebase -i master. In case I ever want to "undo" this, let's back up this branch first! I do this ALL...THE...TIME and find it super helpful and comforting to know I can always easily go back to this backup branch and re-branch off of it to try again in case I mess up feature_branch1 in the process:

git branch feature_branch1_BAK_20200814-1320hrs_about_to_squash

The 20200814-1120hrs part is the date and time in format YYYYMMDD-HHMMhrs, so that would be 13:20hrs (1:20pm) on 14 Aug. 2020. This way I have an easy way to find my backup branches until I'm sure I'm ready to delete them. If you don't do this and you mess up badly, you have to use git reflog to go find your branch prior to messing it up, which is much harder, more stressful, and more error-prone.

3. To create and check out a new branch from the branch you DO have checked out:

git checkout -b new_branch

4. To rename a branch

Just like renaming a regular file or folder in the terminal, git considered "renaming" to be more like a 'm'ove command, so you use git branch -m to rename a branch. Here's the general format:

git branch -m <old_name> <new_name>

man git branch shows it like this:

git branch (-m | -M) [<oldbranch>] <newbranch>

Example: let's rename branch_1 to branch_1.5:

git branch -m branch_1 branch_1.5

To catch Guzzle errors you can do something like this:

try {
    $response = $client->get('/not_found.xml')->send();
} catch (Guzzle\Http\Exception\BadResponseException $e) {
    echo 'Uh oh! ' . $e->getMessage();
}

... but, to be able to "log" or "resend" your request try something like this:

// Add custom error handling to any request created by this client
$client->getEventDispatcher()->addListener(
    'request.error', 
    function(Event $event) {

        //write log here ...

        if ($event['response']->getStatusCode() == 401) {

            // create new token and resend your request...
            $newRequest = $event['request']->clone();
            $newRequest->setHeader('X-Auth-Header', MyApplication::getNewAuthToken());
            $newResponse = $newRequest->send();

            // Set the response object of the request without firing more events
            $event['response'] = $newResponse;

            // You can also change the response and fire the normal chain of
            // events by calling $event['request']->setResponse($newResponse);

            // Stop other events from firing when you override 401 responses
            $event->stopPropagation();
        }

});

... or if you want to "stop event propagation" you can overridde event listener (with a higher priority than -255) and simply stop event propagation.

$client->getEventDispatcher()->addListener('request.error', function(Event $event) {
if ($event['response']->getStatusCode() != 200) {
        // Stop other events from firing when you get stytus-code != 200
        $event->stopPropagation();
    }
});

thats a good idea to prevent guzzle errors like:

request.CRITICAL: Uncaught PHP Exception Guzzle\Http\Exception\ClientErrorResponseException: "Client error response

in your application.

To do this via TSQL (ssms query window or sqlcmd.exe) just run:

RESTORE DATABASE MyDatabase FROM DISK='c:\backups\MyDataBase1.bak'

To do it via GUI - open SSMS, right click on Databases and follow the steps below

Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:

create table foo (
  bar  int[] default '{}'
);

select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]

create index on foo using gin (bar); -- allows to use an index in the above query

But as the prior answer suggests, it will be better to normalize properly.

If you're on Linux or Unix (including OS X), you should put this somewhere that will affect your environment:

export HTTP_PROXY_REQUEST_FULLURI=0 # or false
export HTTPS_PROXY_REQUEST_FULLURI=0 #

You can put it in /etc/profile to globally affect all users on the machine, or your own ~/.bashrc or ~/.zshrc, depending on which shell you use.

If you're on Windows, open the Environment Variables control panel, and add either a system or user environment variables with both HTTP_PROXY_REQUEST_FULLURI and HTTPS_PROXY_REQUEST_FULLURI set to 0 or false.

For other people reading this (not you, since you said you have these set up), make sure HTTP_PROXY and HTTPS_PROXY are set to the correct proxy, using the same methods. If you're on Unix/Linux/OS X, setting both upper and lowercase versions of the variable name is the most complete approach, as some things use only the lowercase version, and IIRC some use the upper case. (I'm often using a sort of hybrid environment, Cygwin on Windows, and I know for me it was important to have both, but pure Unix/Linux environments might be able to get away with just lowercase.)

If you still can't get things working after you've done all this, and you're sure you have the correct proxy address set, then look into whether your company is using a Microsoft proxy server. If so, you probably need to install Cntlm as a child proxy to connect between Composer (etc.) and the Microsoft proxy server. Google CNTLM for more information and directions on how to set it up.

Alternatively,

StringBuilder result = new StringBuilder();
for(String string : collection) {
    result.append(string);
    result.append(',');
}
return result.substring(0, result.length() - 1) ;

Create "topN" query on "clientip" and then histogram with count on "clientip" and set "topN" query as source. Then you will see count of different ips per time.

In my case it was a missing SPN, had to run these two commands:

setspn -a MSSQLSvc:SERVERNAME SERVERNAME setspn -a MSSQLSvc:SERVERNAME:1433 SERVERNAME

In other words in my case I had the FQDN in there already correctly but not just the NETBIOS name, after adding these it worked fine. Well initially it didn't but after waiting 2 minutes it did.

If you want to export it as a file just do Any Collection (...) -> Export. There you should be able to choose collection version format and it will be exported in JSN file.

I would say an enum singleton.

Singleton using an enum in Java is generally a way to declare an enum singleton. An enum singleton may contain instance variables and instance methods. For simplicity's sake, also note that if you are using any instance method then you need to ensure thread safety of that method if at all it affects the state of object.

The use of an enum is very easy to implement and has no drawbacks regarding serializable objects, which have to be circumvented in the other ways.

/**
* Singleton pattern example using a Java Enum
*/
public enum Singleton {
    INSTANCE;
    public void execute (String arg) {
        // Perform operation here
    }
}

You can access it by Singleton.INSTANCE, and it is much easier than calling the getInstance() method on Singleton.

1.12 Serialization of Enum Constants

Enum constants are serialized differently than ordinary serializable or externalizable objects. The serialized form of an enum constant consists solely of its name; field values of the constant are not present in the form. To serialize an enum constant, ObjectOutputStream writes the value returned by the enum constant's name method. To deserialize an enum constant, ObjectInputStream reads the constant name from the stream; the deserialized constant is then obtained by calling the java.lang.Enum.valueOf method, passing the constant's enum type along with the received constant name as arguments. Like other serializable or externalizable objects, enum constants can function as the targets of back references appearing subsequently in the serialization stream.

The process by which enum constants are serialized cannot be customized: any class-specific writeObject, readObject, readObjectNoData, writeReplace, and readResolve methods defined by enum types are ignored during serialization and deserialization. Similarly, any serialPersistentFields or serialVersionUID field declarations are also ignored--all enum types have a fixed serialVersionUID of 0L. Documenting serializable fields and data for enum types is unnecessary, since there is no variation in the type of data sent.

Quoted from Oracle documentation

Another problem with conventional Singletons are that once you implement the Serializable interface, they no longer remain singleton because the readObject() method always return a new instance, like a constructor in Java. This can be avoided by using readResolve() and discarding the newly created instance by replacing with a singleton like below:

 // readResolve to prevent another instance of Singleton
 private Object readResolve(){
     return INSTANCE;
 }

This can become even more complex if your singleton class maintains state, as you need to make them transient, but with in an enum singleton, serialization is guaranteed by the JVM.

You are looking for collections.defaultdict (available for Python 2.5+). This

from collections import defaultdict

my_dict = defaultdict(int)
my_dict[key] += 1

will do what you want.

For regular Python dicts, if there is no value for a given key, you will not get None when accessing the dict -- a KeyError will be raised. So if you want to use a regular dict, instead of your code you would use

if key in my_dict:
    my_dict[key] += 1
else:
    my_dict[key] = 1

I had a similar issues once. I deleted the primary key from TABLE A but when I was trying to delete the foreign key column from table B I was shown the above same error.

You can't drop the foreign key using the column name and to bypass this in PHPMyAdmin or with MySQL, first remove the foreign key constraint before renaming or deleting the attribute.

check the formats here http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

main

System.out.println("date  : " + new classname().getMyDate("2014-01-09 14:06", "dd-MMM-yyyy E hh:mm a z", "yyyy-MM-dd HH:mm"));

method

 public String getMyDate(String myDate, String returnFormat, String myFormat)
            {
                DateFormat dateFormat = new SimpleDateFormat(returnFormat);
                Date date=null;
                String returnValue="";
                try {
                    date = new SimpleDateFormat(myFormat, Locale.ENGLISH).parse(myDate);
                    returnValue = dateFormat.format(date);
                } catch (ParseException e) {
                    returnValue= myDate;
                    System.out.println("failed");
                    e.printStackTrace();
                }

            return returnValue;
            }

You can try writing into the Documents folder. Here is a "debug" function I did for the debugging needs of my project:

Private Sub writeDebug(ByVal x As String)
    Dim path As String = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
    Dim FILE_NAME As String = path & "\mydebug.txt"
    MsgBox(FILE_NAME)
    If System.IO.File.Exists(FILE_NAME) = False Then
        System.IO.File.Create(FILE_NAME).Dispose()
    End If
    Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
    objWriter.WriteLine(x)
    objWriter.Close()
End Sub

There are more standard folders you can access through the "SpecialFolder" object.

A cookie is just another HTTP header. You can always set it while making a HTTP call with the apache library or with HTTPUrlConnection. Either way you should be able to read and set HTTP cookies in this fashion.

You can read this article for more information.

I can share my peace of code to demonstrate how easy you can make it.

public static String getServerResponseByHttpGet(String url, String token) {

        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet get = new HttpGet(url);
            get.setHeader("Cookie", "PHPSESSID=" + token + ";");
            Log.d(TAG, "Try to open => " + url);

            HttpResponse httpResponse = client.execute(get);
            int connectionStatusCode = httpResponse.getStatusLine().getStatusCode();
            Log.d(TAG, "Connection code: " + connectionStatusCode + " for request: " + url);

            HttpEntity entity = httpResponse.getEntity();
            String serverResponse = EntityUtils.toString(entity);
            Log.d(TAG, "Server response for request " + url + " => " + serverResponse);

            if(!isStatusOk(connectionStatusCode))
                return null;

            return serverResponse;

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

Although it has been a while since this question was asked, I will post my answer hoping it helps somebody.

Disclaimer: I know this solution is not standard, but I think it works well.

import pandas as pd
import numpy as np

data = np.array([[10, 2, 10, 10],
                 [10, 3, 60, 100],
                 [np.nan] * 4,
                 [10, 22, 280, 250]]).T
idx = pd.date_range('20150131', end='20150203')
df = pd.DataFrame(data=data, columns=list('ABCD'), index=idx)
df
               A    B     C    D
 =================================
 2015-01-31    10   10    NaN  10
 2015-02-01    2    3     NaN  22 
 2015-02-02    10   60    NaN  280
 2015-02-03    10   100   NaN  250

def calculate(mul, add):
    global value
    value = value * mul + add
    return value

value = df.loc['2015-01-31', 'D']
df.loc['2015-01-31', 'C'] = value
df.loc['2015-02-01':, 'C'] = df.loc['2015-02-01':].apply(lambda row: calculate(*row[['A', 'B']]), axis=1)
df
               A    B     C     D
 =================================
 2015-01-31    10   10    10    10
 2015-02-01    2    3     23    22 
 2015-02-02    10   60    290   280
 2015-02-03    10   100   3000  250

So basically we use a apply from pandas and the help of a global variable that keeps track of the previous calculated value.

Time comparison with a for loop:

data = np.random.random(size=(1000, 4))
idx = pd.date_range('20150131', end='20171026')
df = pd.DataFrame(data=data, columns=list('ABCD'), index=idx)
df.C = np.nan

df.loc['2015-01-31', 'C'] = df.loc['2015-01-31', 'D']

%%timeit
for i in df.loc['2015-02-01':].index.date:
    df.loc[i, 'C'] = df.loc[(i - pd.DateOffset(days=1)).date(), 'C'] * df.loc[i, 'A'] + df.loc[i, 'B']

3.2 s ± 114 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

data = np.random.random(size=(1000, 4))
idx = pd.date_range('20150131', end='20171026')
df = pd.DataFrame(data=data, columns=list('ABCD'), index=idx)
df.C = np.nan

def calculate(mul, add):
    global value
    value = value * mul + add
    return value

value = df.loc['2015-01-31', 'D']
df.loc['2015-01-31', 'C'] = value

%%timeit
df.loc['2015-02-01':, 'C'] = df.loc['2015-02-01':].apply(lambda row: calculate(*row[['A', 'B']]), axis=1)

1.82 s ± 64.4 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

So 0.57 times faster on average.

I am going to assume this is a WinForms questions (which it feels like, based on it being a "program" rather than a website/app). In which case you can simple do the following to change the text colour of a label:

myLabel.ForeColor = System.Drawing.Color.Red;

Or any other colour of your choice. If you want to be more specific you can use an RGB value like so:

myLabel.ForeColor = Color.FromArgb(0, 0, 0);//(R, G, B) (0, 0, 0 = black)

Having different colours for different users can be done a number of ways. For example, you could allow each user to specify their own RGB value colours, store these somewhere and then load them when the user "connects".

An alternative method could be to just use 2 colours - 1 for the current user (running the app) and another colour for everyone else. This would help the user quickly identify their own messages above others.

A third approach could be to generate the colour randomly - however you will likely get conflicting values that do not show well against your background, so I would suggest not taking this approach. You could have a pre-defined list of "acceptable" colours and just pop one from that list for each user that joins.

The above answer only adds the sqljdbc4.jar to the local repository. As a result, when creating the final project jar for distribution, sqljdbc4 will again be missing as was indicated in the comment by @Tony regarding runtime error.

Microsoft (and Oracle and other third party providers) restrict the distribution of their software as per the ENU/EULA. Therefore those software modules do not get added in Maven produced jars for distribution. There are hacks to get around it (such as providing the location of the 3rd party jar file at runtime), but as a developer you must be careful about violating the licensing.

A better approach for jdbc connectors/drivers is to use jTDS, which is compatible to most DBMS's, more reliable, faster (as per benchmarks), and distributed under GNU license. It will make your life much easier to use this than trying to pound the square peg into the round hole following any of the other techniques above.

var obj = eval('(' + "{Date: \/Date(1278903921551)\/}".replace(/\/Date\((\d+)\)\//gi, "new Date($1)") + ')');
var dateValue = obj["Date"];

The answer provided by Evan Mulawski will work perfectly. The catch is that you have to set the background color for the view to clearColor and the masksToBounds property to NO.

You can set whatever color you want for the view, set it like

v.layer.backgroundColor = your color;

Hope this helps..

To get the content of a directory you can use

$files = Get-ChildItem "C:\Users\gerhardl\Documents\My Received Files\"

Then you can loop over this variable as well:

for ($i=0; $i -lt $files.Count; $i++) {
    $outfile = $files[$i].FullName + "out" 
    Get-Content $files[$i].FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

An even easier way to put this is the foreach loop (thanks to @Soapy and @MarkSchultheiss):

foreach ($f in $files){
    $outfile = $f.FullName + "out" 
    Get-Content $f.FullName | Where-Object { ($_ -match 'step4' -or $_ -match 'step9') } | Set-Content $outfile
}

As @Renan mentioned, ng-include creates a new child scope. This scope prototypically inherits (see dashed lines below) from the HomeCtrl scope. ng-model="lineText" actually creates a primitive scope property on the child scope, not HomeCtrl's scope. This child scope is not accessible to the parent/HomeCtrl scope:

To store what the user typed into HomeCtrl's $scope.lines array, I suggest you pass the value to the addLine function:

 <form ng-submit="addLine(lineText)">

In addition, since lineText is owned by the ngInclude scope/partial, I feel it should be responsible for clearing it:

 <form ng-submit="addLine(lineText); lineText=''">

Function addLine() would thus become:

$scope.addLine = function(lineText) {
    $scope.chat.addLine(lineText);
    $scope.lines.push({
        text: lineText
    });
};

Fiddle.

Alternatives:

• define an object property on HomeCtrl's $scope, and use that in the partial: ng-model="someObj.lineText; fiddle
• not recommended, this is more of a hack: use $parent in the partial to create/access a lineText property on the HomeCtrl $scope:  ng-model="$parent.lineText"; fiddle

It is a bit involved to explain why the above two alternatives work, but it is fully explained here: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

I don't recommend using this in the addLine() function. It becomes much less clear which scope is being accessed/manipulated.

None of the answers in this or any other thread on setting HTML attributes for @Html.EditorFor were much help to me. However, I did find a great answer at

Styling an @Html.EditorFor helper

I used the same approach and it worked beautifully without writing a lot of extra code. Note that the id attribute of the html output of Html.EditorFor is set. The view code

<style type="text/css">
#dob
{
   width:6em;
}
</style>

@using (Html.BeginForm())
{
   Enter date: 
   @Html.EditorFor(m => m.DateOfBirth, null, "dob", null)
}

The model property with data annotation and date formatting as "dd MMM yyyy"

[Required(ErrorMessage= "Date of birth is required")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd MMM yyyy}")]
public DateTime DateOfBirth { get; set; }

Worked like a charm without writing a whole lot of extra code. This answer uses ASP.NET MVC 3 Razor C#.

commands also works.

import commands
batcmd = "dir"
result = commands.getoutput(batcmd)
print result

It works on linux, python 2.7.

It's simple and follow the small Steps to proceed:

• Install git on the remote server say some ec2 instance
• Now create a project folder `$mkdir project.git
• $cd project and execute $git init --bare

Let's say this project.git folder is present at your ip with address inside home_folder/workspace/project.git, forex- ec2 - /home/ubuntu/workspace/project.git

Now in your local machine, $cd into the project folder which you want to push to git execute the below commands:

• git init .

• git remote add origin [email protected]:/home/ubuntu/workspace/project.git

• git add .
• git commit -m "Initial commit"

Below is an optional command but found it has been suggested as i was working to setup the same thing

git config --global remote.origin.receivepack "git receive-pack"

• git pull origin master
• git push origin master

This should work fine and will push the local code to the remote git repository.

To check the remote fetch url, cd project_folder/.git and cat config, this will give the remote url being used for pull and push operations.

You can also use an alternative way, after creating the project.git folder on git, clone the project and copy the entire content into that folder. Commit the changes and it should be the same way. While cloning make sure you have access or the key being is the secret key for the remote server being used for deployment.

I had this problem, and I solved it. There was an attribute in the <%@ Page tag named MaintainScrollPositionOnPostback and after removing it, the error disapeared. I added it before to prevent scrolling after each postback.

In addition to the above answers, as part of configuring your firewall, if you are using SSH then use port 22.

For [1], you can't: these operators are made to return a value, not perform operations.

The expression

a ? b : c

evaluates to b if a is true and evaluates to c if a is false.

The expression

b ?? c

evaluates to b if b is not null and evaluates to c if b is null.

If you write

return a ? b : c;

or

return b ?? c;

they will always return something.

For [2], you can write a function that returns the right value that performs your "multiple operations", but that's probably worse than just using if/else.

-- IN arguments : you get them. You can modify them locally but caller won't see it
-- IN OUT arguments: initialized by caller, already have a value, you can modify them and the caller will see it
-- OUT arguments: they're reinitialized by the procedure, the caller will see the final value.
CREATE PROCEDURE f (p IN NUMBER, x IN OUT NUMBER, y OUT NUMBER)

   x:=x * p;
   y:=4 * p;
END;

In my case someone had deleted APN SSL Certificates for my app in Apple development portal.

• I needed to create new certificates: Identifiers / My AppId / Push Notifications / Edit.
• Then I uploaded them to the Firebase project from console: Project Settings / Cloud Messaging / iOS app configuration / APNs Certificates.

This solved the problem.

Add PrivacyBadger to the list of potential causes

If you're unsure about something, try writing a test first.

I did this:

class ClassNameTest {
    public static void main(final String... arguments) {
        printNamesForClass(
            int.class,
            "int.class (primitive)");
        printNamesForClass(
            String.class,
            "String.class (ordinary class)");
        printNamesForClass(
            java.util.HashMap.SimpleEntry.class,
            "java.util.HashMap.SimpleEntry.class (nested class)");
        printNamesForClass(
            new java.io.Serializable(){}.getClass(),
            "new java.io.Serializable(){}.getClass() (anonymous inner class)");
    }

    private static void printNamesForClass(final Class<?> clazz, final String label) {
        System.out.println(label + ":");
        System.out.println("    getName():          " + clazz.getName());
        System.out.println("    getCanonicalName(): " + clazz.getCanonicalName());
        System.out.println("    getSimpleName():    " + clazz.getSimpleName());
        System.out.println("    getTypeName():      " + clazz.getTypeName()); // added in Java 8
        System.out.println();
    }
}

Prints:

int.class (primitive):
    getName():          int
    getCanonicalName(): int
    getSimpleName():    int
    getTypeName():      int

String.class (ordinary class):
    getName():          java.lang.String
    getCanonicalName(): java.lang.String
    getSimpleName():    String
    getTypeName():      java.lang.String

java.util.HashMap.SimpleEntry.class (nested class):
    getName():          java.util.AbstractMap$SimpleEntry
    getCanonicalName(): java.util.AbstractMap.SimpleEntry
    getSimpleName():    SimpleEntry
    getTypeName():      java.util.AbstractMap$SimpleEntry

new java.io.Serializable(){}.getClass() (anonymous inner class):
    getName():          ClassNameTest$1
    getCanonicalName(): null
    getSimpleName():    
    getTypeName():      ClassNameTest$1

There's an empty entry in the last block where getSimpleName returns an empty string.

The upshot looking at this is:

• the name is the name that you'd use to dynamically load the class with, for example, a call to Class.forName with the default ClassLoader. Within the scope of a certain ClassLoader, all classes have unique names.
• the canonical name is the name that would be used in an import statement. It might be useful during toString or logging operations. When the javac compiler has complete view of a classpath, it enforces uniqueness of canonical names within it by clashing fully qualified class and package names at compile time. However JVMs must accept such name clashes, and thus canonical names do not uniquely identify classes within a ClassLoader. (In hindsight, a better name for this getter would have been getJavaName; but this method dates from a time when the JVM was used solely to run Java programs.)
• the simple name loosely identifies the class, again might be useful during toString or logging operations but is not guaranteed to be unique.
• the type name returns "an informative string for the name of this type", "It's like toString: it's purely informative and has no contract value". (as written by sir4ur0n)

You can't. A redirect requires a webserver to accept the first request and send back the redirect. The "hosts" file just lets you set your own DNS records.

convert the string to HashMap using Object Mapper ...

new ObjectMapper().readValue(string, Map.class);

Internally Map will behave as JSON Object

If you are on Ubuntu 14.04 you can find nginx www directory at following path:

yusuf@yusuf-he:/usr/share/nginx/html$ pwd
/usr/share/nginx/html
yusuf@yusuf-he:/usr/share/nginx/html$

Update 2017:

I have done research on how this could be achieved. And the best explanation/tutorial is here: https://tympanus.net/codrops/2015/09/15/styling-customizing-file-inputs-smart-way/

I'll write summary here just in case it becomes unavailable. So you should have HTML:

<input type="file" name="file" id="file" class="inputfile" />
<label for="file">Choose a file</label>

Then hide the input with CSS:

.inputfile {
width: 0.1px;
height: 0.1px;
opacity: 0;
overflow: hidden;
position: absolute;
z-index: -1;}

Then style the label:

.inputfile + label {
font-size: 1.25em;
font-weight: 700;
color: white;
background-color: black;
display: inline-block;
}

Then optionally you can add JS to display the name of the file:

var inputs = document.querySelectorAll( '.inputfile' );
Array.prototype.forEach.call( inputs, function( input )
{
var label    = input.nextElementSibling,
    labelVal = label.innerHTML;

input.addEventListener( 'change', function( e )
{
    var fileName = '';
    if( this.files && this.files.length > 1 )
        fileName = ( this.getAttribute( 'data-multiple-caption' ) || '' ).replace( '{count}', this.files.length );
    else
        fileName = e.target.value.split( '\\' ).pop();

    if( fileName )
        label.querySelector( 'span' ).innerHTML = fileName;
    else
        label.innerHTML = labelVal;
});
});

But really just read the tutorial and download the demo, it's really good.

Just in case it helps another, I finally solved this problem, that was apparently caused by python version conflicts, by redirecting the link python3, then redirecting it to the right python version:

sudo rm /usr/bin/python3
sudo ln -s /usr/bin/python3.4

You may need to enter the correct python version, found with:

python3 -V

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

ng-Idle looks like the way to go, but I could not figure out Brian F's modifications and wanted to timeout for a sleeping session too, also I had a pretty simple use case in mind. I pared it down to the code below. It hooks events to reset a timeout flag (lazily placed in $rootScope). It only detects the timeout has happened when the user returns (and triggers an event) but that's good enough for me. I could not get angular's $location to work here but again, using document.location.href gets the job done.

I stuck this in my app.js after the .config has run.

app.run(function($rootScope,$document) 
{
  var d = new Date();
  var n = d.getTime();  //n in ms

    $rootScope.idleEndTime = n+(20*60*1000); //set end time to 20 min from now
    $document.find('body').on('mousemove keydown DOMMouseScroll mousewheel mousedown touchstart', checkAndResetIdle); //monitor events

    function checkAndResetIdle() //user did something
    {
      var d = new Date();
      var n = d.getTime();  //n in ms

        if (n>$rootScope.idleEndTime)
        {
            $document.find('body').off('mousemove keydown DOMMouseScroll mousewheel mousedown touchstart'); //un-monitor events

            //$location.search('IntendedURL',$location.absUrl()).path('/login'); //terminate by sending to login page
            document.location.href = 'https://whatever.com/myapp/#/login';
            alert('Session ended due to inactivity');
        }
        else
        {
            $rootScope.idleEndTime = n+(20*60*1000); //reset end time
        }
    }
});

This works for me on [{"id":"data"},{"id":"data"}]

function getObjects(obj, key, val) 
{
    var newObj = false; 
    $.each(obj, function()
    {
        var testObject = this; 
        $.each(testObject, function(k,v)
        {
            //alert(k);
            if(val == v && k == key)
            {
                newObj = testObject;
            }
        });
    });

    return newObj;
}

Just a tip for this, you don't need the BEGIN and END if it only contains a single statement.

ie:

IF(@Trans_type = 'subscr_signup')    
 set @tmpType = 'premium' 
ELSE iF(@Trans_type = 'subscr_cancel')  
     set    @tmpType = 'basic'

I find this shorter and cleaner. Besides, you can iterate through selected items if there are more than one;

$('select').on('change', function () {
     var selectedValue = this.selectedOptions[0].value;
     var selectedText  = this.selectedOptions[0].text;
});

I know this thread is bit old. But I'm going to post this anyway hoping it might help someone. We can store fields of any Object to shared preference by serializing the object to String. Here I have used GSON for storing any object to shared preference.

Save Object to Preference :

public static void saveObjectToSharedPreference(Context context, String preferenceFileName, String serializedObjectKey, Object object) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    SharedPreferences.Editor sharedPreferencesEditor = sharedPreferences.edit();
    final Gson gson = new Gson();
    String serializedObject = gson.toJson(object);
    sharedPreferencesEditor.putString(serializedObjectKey, serializedObject);
    sharedPreferencesEditor.apply();
}

Retrieve Object from Preference:

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Class<GenericClass> classType) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    if (sharedPreferences.contains(preferenceKey)) {
        final Gson gson = new Gson();
        return gson.fromJson(sharedPreferences.getString(preferenceKey, ""), classType);
    }
    return null;
}

Note :

Remember to add compile 'com.google.code.gson:gson:2.6.2' to dependencies in your gradle.

Example :

//assume SampleClass exists
SampleClass mObject = new SampleObject();

//to store an object
saveObjectToSharedPreference(context, "mPreference", "mObjectKey", mObject);

//to retrive object stored in preference
mObject = getSavedObjectFromPreference(context, "mPreference", "mObjectKey", SampleClass.class);

Update:

As @Sharp_Edge pointed out in comments, the above solution does not work with List.

A slight modification to the signature of getSavedObjectFromPreference() - from Class<GenericClass> classType to Type classType will make this solution generalized. Modified function signature,

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Type classType)

For invoking,

getSavedObjectFromPreference(context, "mPreference", "mObjectKey", (Type) SampleClass.class)

Happy Coding!

To compare two objects you can use:

angular.equals(obj1, obj2)

It does a deep comparison and does not depend on the order of the keys See AngularJS DOCS and a little Demo

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

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

angular.equals(obj1, obj2) //<--- would return true

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

const events = new Events();

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

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

events.on('blockIsHidden', printText);

Couple of points:

• I believe git stash + git stash drop could be replaced with git reset --hard

• ... or, even shorter, add -f to checkout command:

  git checkout -f -b $branch
  

  That will discard any local changes, just as if git reset --hard was used prior to checkout.

As for the main question: instead of pulling in the last step, you could just merge the appropriate branch from the remote into your local branch: git merge $branch origin/$branch, I believe it does not hit the remote. If that is the case, it removes the need for credensials and hence, addresses your biggest concern.

Class

When you define a class, you define a blueprint for a data type. class hold data, have method that interact with that data and are used to instantiate objects.

Module

• Modules are a way of grouping together methods, classes, and constants.

• Modules give you two major benefits:

  => Modules provide a namespace and prevent name clashes. Namespace help avoid conflicts with functions and classes with the same name that have been written by someone else.

  => Modules implement the mixin facility.

(including Module in Klazz gives instances of Klazz access to Module methods. )

(extend Klazz with Mod giving the class Klazz access to Mods methods.)

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

I used below function to compare two strings and It is working good.

function CompareUserId (first, second)
{

   var regex = new RegExp('^' + first+ '$', 'i');
   if (regex.test(second)) 
   {
        return true;
   }
   else 
   {
        return false;
   }
   return false;
}

Your error message is pretty explicit about what is going wrong:

laravel/framework v5.2.9 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

Do you have mbstring installed on your server and is it enabled?

You can install mbstring as part of the libapache2-mod-php5 package:

sudo apt-get install libapache2-mod-php5

Or standalone with:

sudo apt-get install php-mbstring

Installing it will also enable it, however you can also enable it by editing your php.ini file and remove the ; that is commenting it out if it is already installed.

If this is on your local machine, then follow the appropriate steps to install this on your environment.

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

In Rails 6 there is a convenient way for resetting DB and planting seeds again:

rails db:seed:replant # Truncates tables of each database for current environment and loads the seeds

https://weblog.rubyonrails.org/2019/3/15/this-week-in-rails-security-fixes-bulk-insert-and-upsert-seeds-replanting/

Yep:

WITH tab (
  bla bla
)

INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos (  BatchID,                                                        AccountNo,
APartyNo,
SourceRowID)    

SELECT * FROM tab

Note that this is for SQL Server, which supports multiple CTEs:

WITH x AS (), y AS () INSERT INTO z (a, b, c) SELECT a, b, c FROM y

Teradata allows only one CTE and the syntax is as your example.

If you want to take advantage of recent Python versions' async features, you can use aioftp (from the same family of libraries and developers as the more popular aiohttp library). Here is a code example taken from their client tutorial:

client = aioftp.Client()
await client.connect("ftp.server.com")
await client.login("user", "pass")
await client.download("tmp/test.py", "foo.py", write_into=True)

As described in Cast Functions and Operators:

The type for the result can be one of the following values:

• BINARY[(N)]
• CHAR[(N)]
• DATE
• DATETIME
• DECIMAL[(M[,D])]
• SIGNED [INTEGER]
• TIME
• UNSIGNED [INTEGER]

Therefore, you should use:

SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT

If you're using Visual Studio 2013 (may require Pro edition or higher), I was able to add a virtual directory to an IIS Express (file-based) website by right-clicking on the website in the Solution Explorer and clicking Add > New Virtual Directory. This added an entry to the applicationhost.config file as with the manual methods described here.

I think your second option is the best bet. Generally in floating-point comparison you often only care that one value is within a certain tolerance of another value, controlled by the selection of epsilon.

This will do the job just fine , and even handle subdirs being specified:

    $(CC) $(CFLAGS) -MD -o $@ $<

tested it with gcc 4.8.3

1. Add the files to a folder called LocalPackages next to you solution (it doesn't have to be called that, but adjust the xml in the following step accordingly)

2. Create a file called NuGet.config next to your solution file with the following contents

   <?xml version="1.0" encoding="utf-8"?>
     <configuration>
       <packageSources>
         <add key="LocalPackages" value="./LocalPackages" />
       </packageSources>
       <activePackageSource>
         <!-- this tells that all of them are active -->
         <add key="All" value="(Aggregate source)" />
       </activePackageSource>
    </configuration>
   

3. If the solution is open in Visual Studio, close it, then re-open it.

Now your packages should appear in the browser, or be installable using Install-Package

For me this happened when I tried to run on a device with a newer version of iOS than supported by the version of Xcode I was running.

Webkit seems to use internally display: table-row-group for the tbody tag. There is currently a bug with setting height to it: https://github.com/w3c/csswg-drafts/issues/476

Let's hope it will be solved soon.

.input:focus {
    outline: none !important;
    border:1px solid red;
    box-shadow: 0 0 10px #719ECE;
}

All given answers work fine, but I remember learning that using setAlpha can be a bad idea performance wise (more info here). So creating a StateListDrawable is a better idea to manage disabled state of buttons. Here's how:

Create a XML btn_blue.xml in res/drawable folder:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Disable background -->
    <item android:state_enabled="false"
          android:color="@color/md_blue_200"/>
    
    <!-- Enabled background -->
    <item android:color="@color/md_blue_500"/>
</selector>

Create a button style in res/values/styles.xml

<style name="BlueButton" parent="ThemeOverlay.AppCompat">
      <item name="colorButtonNormal">@drawable/btn_blue</item>
      <item name="android:textColor">@color/md_white_1000</item>
</style>

Then apply this style to your button:

<Button
     android:id="@+id/my_disabled_button"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:theme="@style/BlueButton"/>

Now when you call btnBlue.setEnabled(true) OR btnBlue.setEnabled(false) the state colors will automatically switch.

And the result is..

The 4 div span with no gutter will remain spanned for Small tablet landscape (800x600). Anything size smaller than that will collapse the 4 divs and it will be stacked vertically. Of course you will have to tweak it to fit your needs.

Try this:

Swift 2.0:

textField.userInteractionEnabled = false

Swift 3.0:

textField.isUserInteractionEnabled = false

Or in storyboard uncheck "User Interaction Enabled"

The using syntax has an advantage when used within templates. If you need the type abstraction, but also need to keep template parameter to be possible to be specified in future. You should write something like this.

template <typename T> struct whatever {};

template <typename T> struct rebind
{
  typedef whatever<T> type; // to make it possible to substitue the whatever in future.
};

rebind<int>::type variable;

template <typename U> struct bar { typename rebind<U>::type _var_member; }

But using syntax simplifies this use case.

template <typename T> using my_type = whatever<T>;

my_type<int> variable;
template <typename U> struct baz { my_type<U> _var_member; }

Hi there is a way to write and read the dictionary to file you can turn your dictionary to JSON format and read and write quickly just do this :

To write your date:

 import json

 your_dictionary = {"some_date" : "date"}
 f = open('destFile.txt', 'w+')
 f.write(json.dumps(your_dictionary))

and to read your data:

 import json

 f = open('destFile.txt', 'r')
 your_dictionary = json.loads(f.read())

One easy solution is to use overflow values other than visible to make the text flex basis width reset as expected.

1. Here with value auto the text wraps as expected and the article content does not overflow main container.

2. Also, the article flex value must either have a auto basis AND be able to shrink, OR, only grow AND explicit 0 basis

main, aside, article {_x000D_
  margin: 10px;_x000D_
  border: solid 1px #000;_x000D_
  border-bottom: 0;_x000D_
  height: 50px;_x000D_
  overflow: auto; /* 1. overflow not `visible` */_x000D_
}_x000D_
main {_x000D_
  display: flex;_x000D_
}_x000D_
aside {_x000D_
  flex: 0 0 200px;_x000D_
}_x000D_
article {_x000D_
  flex: 1 1 auto; /* 2. Allow auto width content to shrink */_x000D_
  /* flex: 1 0 0; /* Or, explicit 0 width basis that grows */_x000D_
}

If you are aware of Jackson 2, there is a great tutorial at mkyong.com on how to convert Java Objects to JSON and vice versa. The following code snippets have been taken from that tutorial.

Convert Java object to JSON, writeValue(...):

ObjectMapper mapper = new ObjectMapper();
Staff obj = new Staff();

//Object to JSON in file
mapper.writeValue(new File("c:\\file.json"), obj);

//Object to JSON in String
String jsonInString = mapper.writeValueAsString(obj);

Convert JSON to Java object, readValue(...):

ObjectMapper mapper = new ObjectMapper();
String jsonInString = "{'name' : 'mkyong'}";

//JSON from file to Object
Staff obj = mapper.readValue(new File("c:\\file.json"), Staff.class);

//JSON from URL to Object
Staff obj = mapper.readValue(new URL("http://mkyong.com/api/staff.json"), Staff.class);

//JSON from String to Object
Staff obj = mapper.readValue(jsonInString, Staff.class);

Jackson 2 Dependency:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.6.3</version>
</dependency>

For the full tutorial, please go to the link given above.

You can do this method: "IntSummaryStatistics"

IntSummaryStatistics insum = li.stream().filter(v-> v%2==0).mapToInt(mapper->mapper).summaryStatistics();

You can try using AppDomain.UnhandledException and see if that lets you catch it.

**EDIT*

Here is some more information that might be useful (it's a long read).

For a maven eclipse web project, changing dynamic web module version needs to check three places. If one uses eclipse, and after you have checked the following: 1) web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

2) maven:

<dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.0.1</version>
      <scope>provided</scope>   ## ensure you have tomcat 7 not other version
</dependency>

<plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.0</version>
      <configuration>
            <source>1.7</source> ## at least 6
            <target>1.7</target>
      </configuration>
</plugin>

3) eclipse build path and compiler version is 1.7

you still have an error marker at maven:

cannot change version of project facet dynamic web module to 3.0 one or more constrants have not been satisfied

Then you can: uncheck the dynamic web module, and recheck it. I think it is because .settings of eclipse file is corrupted somehow. About the second tip tomcat which version is a good note.

public void Test(){

     WebElement sign = fc.findElement(By.xpath(".//*[@id='login-scroll']/a"));
        sign.click();
        WebElement LoginAsGuest=fc.findElement(By.xpath(".//*[@id='guest-login-option']"));
        LoginAsGuest.click();
        WebElement email_id= fc.findElement(By.xpath(".//*[@id='guestemail']"));
        email_id.sendKeys("[email protected]");
        WebElement ContinueButton=fc.findElement(By.xpath(".//*[@id='contibutton']"));
        ContinueButton.click();

}

My solution is more simple than the other answers provided and doesn't have the downsides.

It preserves the Error prototype chain and all properties on Error without needing specific knowledge of them. It's been tested in Chrome, Firefox, Node, and IE11.

The only limitation is an extra entry at the top of the call stack. But that is easily ignored.

Here's an example with two custom parameters:

function CustomError(message, param1, param2) {
    var err = new Error(message);
    Object.setPrototypeOf(err, CustomError.prototype);

    err.param1 = param1;
    err.param2 = param2;

    return err;
}

CustomError.prototype = Object.create(
    Error.prototype,
    {name: {value: 'CustomError', enumerable: false}}
);

Example Usage:

try {
    throw new CustomError('Something Unexpected Happened!', 1234, 'neat');
} catch (ex) {
    console.log(ex.name); //CustomError
    console.log(ex.message); //Something Unexpected Happened!
    console.log(ex.param1); //1234
    console.log(ex.param2); //neat
    console.log(ex.stack); //stacktrace
    console.log(ex instanceof Error); //true
    console.log(ex instanceof CustomError); //true
}

For environments that require a polyfil of setPrototypeOf:

Object.setPrototypeOf = Object.setPrototypeOf || function (obj, proto) {
    obj.__proto__ = proto;
    return obj;
};

library(tidyverse)

x <- data.frame(Category= c('First', 'First', 'First', 'Second', 'Third', 'Third', 'Second'), 
           Frequency = c(10, 15, 5, 2, 14, 20, 3))

count(x, Category, wt = Frequency)

If you use Eclipse as your IDE I would recommend the excellent eclipse plugin memory analyzer

Another option is to use JVisualVM, it can read (and create) heap dumps as well, and is shipped with every JDK. You can find it in the bin directory of your JDK.

System is a final class from the java.lang package.

out is a class variable of type PrintStream declared in the System class.

println is a method of the PrintStream class.

But in my opinion one important thing.

The "char(number)" it's lenght of variable.

If we've got table with "Names" like for example [Test1..Test200] and we declare char(5) in SELECT like:

DECLARE @variable char(5)
SET @variable = 'Test1%'
SELECT * FROM table WHERE Name like @variable

the result will be only - "Test1"! (char(5) - 5 chars in lenght; Test11 is 6 )

The rest of potential interested data like [Test11..Test200] will not be returned in the result.

It's ok if we want to limit the SELECT by this way. But if it's not intentional way of doing it could return incorrect results from planned ( Like "all Names begining with Test1..." ).

In my opinion if we don't know the precise lenght of a SELECTed value, a better solution could be something like this one:

DECLARE @variable varchar(max)
SET @variable = 'Test1%'
SELECT * FROM <table> WHERE variable1 like @variable

This returns (Test1 but also Test11..Test19 and Test100..Test199).

I used starikovs' solution. I started with a bash window and gave the commands

cd ~
touch .bashrc

Then I found the .bashrc file in windows explorer, opened it with notepad++ and added

PATH=$PATH:"C:\Program Files (x86)\Notepad++"

so that bash knows where to find Notepad++. (Having Notepad++ in the bash PATH is a useful thing on its own!) Then I pasted his line

git config --global core.editor "notepad++.exe -multiInst"

into a bash window. I started a new bash window for a git repository to test things with the command

git rebase -i HEAD~10

and the file opened in Notepad++ as hoped.

Python also has super as well:

super(type[, object-or-type])

Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped.

Example:

class A(object):     # deriving from 'object' declares A as a 'new-style-class'
    def foo(self):
        print "foo"

class B(A):
    def foo(self):
        super(B, self).foo()   # calls 'A.foo()'

myB = B()
myB.foo()

Or if you want a ripple pulse effect, you could use this:

http://jsfiddle.net/Fy8vD/3041/

.gps_ring {
     border: 2px solid #fff;
     -webkit-border-radius: 50%;
     height: 18px;
     width: 18px;
     position: absolute;
     left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0;
}
.gps_ring:before {
    content:"";
    display:block;
    border: 2px solid #fff;
    -webkit-border-radius: 50%;
    height: 30px;
    width: 30px;
    position: absolute;
    left:-8px;
    top:-8px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-delay: 0.1s;
    opacity: 0.0;
}
.gps_ring:after {
    content:"";
    display:block;
    border:2px solid #fff;
    -webkit-border-radius: 50%;
    height: 50px;
    width: 50px;
    position: absolute;
    left:-18px;
    top:-18px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    -webkit-animation-delay: 0.2s;
    opacity: 0.0;
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You can also check out SQL Azure Data Sync in the Windows Azure Management Portal. It allows you to retrieve and restore an entire database, including schema and data between SQL Azure and SQL Server.

Here you have an example I took from my own project, i have just removed what i thought we didnt need for the example.

import React, { Component } from 'react';
import {
  Text,
  TouchableOpacity,
  View,
  StyleSheet,
  Dimensions,
  Image
} from 'react-native';

class YourComponent extends Component {
  constructor(props) {
    super(props);

    this._makeYourEffectHere = this._makeYourEffectHere.bind(this);

    this.state = {
        showPassword: false,
        image: '../statics/showingPassImage.png'
    }
  }

  render() {
    return (
      <View style={styles.container}>
        <TouchableOpacity style={styles.button} onPress={this._makeYourEffectHere}>
          <Text>button</Text>
          <Image style={styles.image} source={require(this.state.image)}></Image>
        </TouchableOpacity>
        <TextInput password={this.state.showPassword} style={styles.input} value="abc" />
      </View>
    );
  }

  _makeYourEffectHere() {
    var png = this.state.showPassword ? '../statics/showingPassImage.png' : '../statics/hidingPassImage.png';
    this.setState({showPassword: !this.state.showPassword, image: png});
  }
}

var styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    justifyContent: 'center',
    flexDirection: 'column',
    alignItems: 'center',
  },
  button: {
    width: Dimensions.get('window').width * 0.94,
    height: 40,
    backgroundColor: '#3b5998',
    marginTop: Dimensions.get('window').width * 0.03,
    justifyContent: 'center',
    borderRadius: Dimensions.get('window').width * 0.012
  },
  image: {
    width: 25,
    height: 25,
    position: 'absolute',
    left: 7,
    bottom: 7
  },
  input: {
    width: Dimensions.get('window').width * 0.94,
    height: 30
  }
});

module.exports = YourComponent;

I hope It helps you.

Let me know if it was useful.

I have come to the conclusion that this is not possible without any plugins.

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"
End Function

An easy way of doing this is :

1. Download the respective SRC files/folder.

2. In the eclipse editor, Ctrl+click or F3 on a method/class you need the source for. A new tab opens up which says "No attached source found".

3. Click the "attach sources" button, click the "attach source folder" button, browse to the location of the downloaded SRC folder. Done!

(p.s : Button labels may vary slightly, but this is pretty much it.)

You can use regular expression operator (~), separated by (|) as described in Pattern Matching

select column_a from table where column_a ~* 'aaa|bbb|ccc'

import json
with open('result.json', 'w') as fp:
    json.dump(sample, fp)

This is an easier way to do it.

In the second line of code the file result.json gets created and opened as the variable fp.

In the third line your dict sample gets written into the result.json!

You can use this one and it's best practice.

SingleChildScrollView(
  child: Column(
    children: <Widget>[
      //Your Widgets
      //Your Widgets,
      //Your Widgets
    ],
  ),
);
