You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

You might have an undefined property in the object. If using the method of Object.keys(data).length is used those properties will also be counted.

You might want to filter them out out.

Object.keys(data).filter((v) => {return data[v] !== undefined}).length

In line with @Qwertie's suggestion, but going further on the lazy side, you could just pretend that each byte is a ISO-8859-1 character. For the uninitiated, ISO-8859-1 is a single-byte encoding that matches the first 256 code points of Unicode.

So @Ash's answer is actually redeemable with a charset:

byte[] args2 = getByteArry();
String byteStr = new String(args2, Charset.forName("ISO-8859-1"));

This encoding has the same readability as BAIS, with the advantage that it is processed faster than either BAIS or base64 as less branching is required. It might look like the JSON parser is doing a bit more, but it's fine because dealing with non-ASCII by escaping or by UTF-8 is part of a JSON parser's job anyways. It could map better to some formats like MessagePack with a profile.

Space-wise however, it is usually a loss, as nobody would be using UTF-16 for JSON. With UTF-8 each non-ASCII byte would occupy 2 bytes, while BAIS uses (2+4n + r?(r+1):0) bytes for every run of 3n+r such bytes (r is the remainder).

First you download ODBC driver psqlodbc_09_01_0200-x64.zip then you installed it.After that go to START->Program->Administrative tools then you select Data Source ODBC then you double click on the same after that you select PostgreSQL 30 then you select configure then you provide proper details such as db name user Id host name password of the same database in this way you will configured your DSN connection.After That you will check SSL should be allow .

Then you go on next tab system DSN then you select ADD tabthen select postgreSQL_ANSI_64X ODBC after you that you have created PostgreSQL ODBC connection.

Suppose there is a Utility class, then sample code would be -

    URL url = Utility.class.getClassLoader().getResource("customLocation/".concat("abc.txt"));

CustomLocation - if any folder structure within resources otherwise remove this string literal.

If your file is already staged (happens when you do a git add etc after the file is edited) to unstage your changes.

Use

git reset HEAD <file>

Then

git checkout <file>

If not already staged, just use

git checkout <file>

Assuming you mean the letters of the English alphabet...

    for ( int i = 0; i < 26; i++ )
    {
        Console.WriteLine( Convert.ToChar( i + 65 ) );
    }
    Console.WriteLine( "Press any key to continue." );
    Console.ReadKey();

Agree @Drixson Oseña: You should not write localhost/xampp/...., else write for e.g: localhost/mw-config/index.php

Step 1: Highlight the entire column (not including the header) of the column you wish to populate

Step 2: (Using Kutools) On the Insert dropdown, click "Fill Custom List"

Step 3: Click Edit

Step 4: Create your list (For Ex: 1, 2)

Step 5: Choose your new custom list and then click "Fill Range"

DONE!!!

It's running every minute of the hour 22 I guess. Try the following to run it every first minute of the hour 22:

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

In addition to the Eclipse solutions and the tool mentioned in another answer, consider flip. It can 'flip' either way between normal and Windows linebreaks, and does nice things like preserve the file's timestamp and other stats.

You can use it like this to solve your problem:

find . -type f -not -path './.git/*' -exec flip -u {} \;

(I put in a clause to ignore your .git directory, in case you use git, but since flip ignores binary files by default, you mightn't need this.)

Java does not provide very full-featured splitting utilities, so the Guava libraries do:

Iterable<String> pieces = Splitter.fixedLength(3).split(string);

Check out the Javadoc for Splitter; it's very powerful.

In this case, I tried to execute a .py which active a path/file.sql.

My solution was to modify the codification of the file.sql to "UTF-8 without BOM" and it works!

You can do it with Notepad++.

i will leave a part of my code.

/Code/

con=psycopg2.connect(host = sys.argv[1], port = sys.argv[2],dbname = sys.argv[3],user = sys.argv[4], password = sys.argv[5])

cursor = con.cursor() sqlfile = open(path, 'r')

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

The problem with this

for (var key in validation_messages) {
   var obj = validation_messages[key];
   for (var prop in obj) {
      alert(prop + " = " + obj[prop]);
   }
}

is that you’ll also loop through the primitive object's prototype.

With this one you will avoid it:

for (var key in validation_messages) {
   if (validation_messages.hasOwnProperty(key)) {
      var obj = validation_messages[key];
      for (var prop in obj) {
         if (obj.hasOwnProperty(prop)) {
            alert(prop + " = " + obj[prop]);
         }
      }
   }
}

You can tell whether Apache is using preform or worker by issuing the following command

apache2ctl -l

In the resulting output, look for mentions of prefork.c or worker.c

ko.applyBindings accepts a second parameter that is a DOM element to use as the root.

This would let you do something like:

<div id="one">
  <input data-bind="value: name" />
</div>

<div id="two">
  <input data-bind="value: name" />
</div>

<script type="text/javascript">
  var viewModelA = {
     name: ko.observable("Bob")
  };

  var viewModelB = {
     name: ko.observable("Ted")
  };

  ko.applyBindings(viewModelA, document.getElementById("one"));
  ko.applyBindings(viewModelB, document.getElementById("two"));
</script>

So, you can use this technique to bind a viewModel to the dynamic content that you load into your dialog. Overall, you just want to be careful not to call applyBindings multiple times on the same elements, as you will get multiple event handlers attached.

You can't store "no character" in a character - it doesn't make sense.

As an alternative you could store a character that has a special meaning to you - e.g. null char '\0' - and treat this specially.

Canonical without using frameworks with added trim prototype for older browsers

<html>
<head>
<script type="text/javascript">
// add trim to older IEs
if (!String.trim) {
  String.prototype.trim = function() {return this.replace(/^\s+|\s+$/g, "");};
}

window.onload=function() { // onobtrusively adding the submit handler
  document.getElementById("form1").onsubmit=function() { // needs an ID
    var val = this.textField1.value; // 'this' is the form 
    if (val==null || val.trim()=="") { 
      alert('Please enter something');
      this.textField1.focus();
      return false; // cancel submission
    }
    return true; // allow submit
  }
}
</script>
</head>
<body>
<form id="form1">
  <input type="text" name="textField1" value="" /><br/>
  <input type="submit" />
</form>
</body>
</html>

Here is the inline version, although not recommended I show it here in case you need to add validation without being able to refactor the code

function validate(theForm) { // passing the form object
  var val = theForm.textField1.value;
  if (val==null || val.trim()=="") { 
    alert('Please enter something');
    theForm.textField1.focus();
    return false; // cancel submission
  }
  return true; // allow submit
}

passing the form object in (this)

<form onsubmit="return validate(this)">
  <input type="text" name="textField1" value="" /><br/>
  <input type="submit" />
</form>

Although alert(msg); works in those "I just want to find out whats going on" scenarios... every developer has encountered that case where you end up in a (very large or endless) loop that you can't break out of.

I'd recommend that during development if you want a very in-your-face debug option, use a debug option that lets you break out. (PS Opera, Safari? and Chrome? all have this available in their native dialogs)

//global flag
_debug = true;
function debug(msg){
  if(_debug){
    if(!confirm(msg + '\n\nPress Cancel to stop debugging.')){
      _debug = false;
    }
  }
}

With the above you can get your self into a large loop of popup debugging, where pressing Enter/Ok lets you jump through each message, but pressing Escape/Cancel lets you break out nicely.

Use

<% String username = (String)request.getSession().getAttribute(...); %>

Note that your use of <%! ... %> is translated to class-level, but request is only available in the service() method of the translated servlet.

See how JSP code is translated to a servlet.

I have successfully used as shown below in Jenkinsfile:

steps {
  script {
    def reportPath = "${WORKSPACE}/target/report"
    ...
  }
}

An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2.VideoCapture.

Usually, RTSP or HTTP protocol is used by the camera to stream video. An example of IP camera streaming URL is as follows:

rtsp://192.168.1.64/1

It can be opened with OpenCV like this:

capture = cv2.VideoCapture('rtsp://192.168.1.64/1')

Most of the IP cameras have a username and password to access the video. In such case, the credentials have to be provided in the streaming URL as follows:

capture = cv2.VideoCapture('rtsp://username:[email protected]/1')

$watch first parameter can be angular expression or function. See documentation on $scope.$watch. It contains a lot of useful info about how $watch method works: when watchExpression is called, how angular compares results, etc.

    The one caveat to this technique is that ##ContextSpecificGlobal__Temp should ALWAYS have the exact same columns.  
    So make up your global temp table name in the sproc you're using it in and only there!
    In this example I wanted to pass in the name of a global temporary table dynamically.  I have 1 procedure dropping 
    off temporary data in whatever @TableSrc is and another procedure picking it up but we are dynamically passing 
    in the name of our pickup table as a parameter for OPENQUERY.

IF ( OBJECT_ID('tempdb..##ContextSpecificGlobal__Temp' , 'U') IS NULL )
    EXEC ('SELECT * INTO ##ContextSpecificGlobal__Temp FROM OPENQUERY(loopback, ''Select *,''''' +  @guid +''''' as tempid FROM ' + @TableSrc + ''')')
ELSE 
    EXEC ('INSERT ##ContextSpecificGlobal__Temp SELECT * FROM OPENQUERY(loopback, ''Select *,''''' +  @guid +''''' as tempid FROM ' + @TableSrc + ''')')

--If this proc is run frequently we could run into race conditions, that's why we are adding a guid and only deleting
--the data we added to ##ContextSpecificGlobal__Temp
SELECT * INTO #TableSrc FROM ##ContextSpecificGlobal__Temp WHERE tempid = @guid

BEGIN TRAN t1
    IF ( OBJECT_ID('tempdb..##ContextSpecificGlobal__Temp' , 'U') IS NOT NULL ) 
    BEGIN
        -- Here we wipe out our left overs if there if everyones done eating the data
        IF (SELECT COUNT(*) FROM ##ContextSpecificGlobal__Temp) = 0
            DROP TABLE ##ContextSpecificGlobal__Temp
    END
COMMIT TRAN t1

-- YEAH! Now I can use the data from my openquery without wrapping the whole !$#@$@ thing in a string.

This is an interesting old question. I'm adding an answer because nobody noticed a couple of things with the original question.

Which is faster: Convert.ToDouble or Double.TryParse? Which is safer: Convert.ToDouble or Double.TryParse?

I'm going to answer both these questions (I'll update the answer later), in detail, but first:

For safety, the thing every programmer missed in this question is the line (emphasis mine):

It adds only data that are numbers with a few digits (1000 1000,2 1000,34 - comma is a delimiter in Russian standards).

Followed by this code example:

Convert.ToDouble(regionData, CultureInfo.CurrentCulture);

What's interesting here is that if the spreadsheets are in Russian number format but Excel has not correctly typed the cell fields, what is the correct interpretation of the values coming in from Excel?

Here is another interesting thing about the two examples, regarding speed:

catch (InvalidCastException)
{
    // is not a number
}

This is likely going to generate MSIL that looks like this:

catch [mscorlib]System.InvalidCastException 
{
  IL_0023:  stloc.0
  IL_0024:  nop
  IL_0025:  ldloc.0
  IL_0026:  nop
  IL_002b:  nop
  IL_002c:  nop
  IL_002d:  leave.s    IL_002f
}  // end handler
IL_002f: nop
IL_0030: return

In this sense, we can probably compare the total number of MSIL instructions carried out by each program - more on that later as I update this post.

I believe code should be Correct, Clear, and Fast... In that order!

Assuming your stream is not backed by a socket (so you can't use Socket.setSoTimeout()), I think the standard way of solving this type of problem is to use a Future.

Suppose I have the following executor and streams:

    ExecutorService executor = Executors.newFixedThreadPool(2);
    final PipedOutputStream outputStream = new PipedOutputStream();
    final PipedInputStream inputStream = new PipedInputStream(outputStream);

I have writer that writes some data then waits for 5 seconds before writing the last piece of data and closing the stream:

    Runnable writeTask = new Runnable() {
        @Override
        public void run() {
            try {
                outputStream.write(1);
                outputStream.write(2);
                Thread.sleep(5000);
                outputStream.write(3);
                outputStream.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
    executor.submit(writeTask);

The normal way of reading this is as follows. The read will block indefinitely for data and so this completes in 5s:

    long start = currentTimeMillis();
    int readByte = 1;
    // Read data without timeout
    while (readByte >= 0) {
        readByte = inputStream.read();
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }
    System.out.println("Complete in " + (currentTimeMillis() - start) + "ms");

which outputs:

Read: 1
Read: 2
Read: 3
Complete in 5001ms

If there was a more fundamental problem, like the writer not responding, the reader would block for ever. If I wrap the read in a future, I can then control the timeout as follows:

    int readByte = 1;
    // Read data with timeout
    Callable<Integer> readTask = new Callable<Integer>() {
        @Override
        public Integer call() throws Exception {
            return inputStream.read();
        }
    };
    while (readByte >= 0) {
        Future<Integer> future = executor.submit(readTask);
        readByte = future.get(1000, TimeUnit.MILLISECONDS);
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }

which outputs:

Read: 1
Read: 2
Exception in thread "main" java.util.concurrent.TimeoutException
    at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:228)
    at java.util.concurrent.FutureTask.get(FutureTask.java:91)
    at test.InputStreamWithTimeoutTest.main(InputStreamWithTimeoutTest.java:74)

I can catch the TimeoutException and do whatever cleanup I want.

The following code sample, will match the pattern even in case of space characters in between. i.e. :

<td><a href='/path/to/file'>Name of File</a></td>

as well as:

<td> <a      href='/path/to/file' >Name of File</a>  </td>

Method returns true or false, depending on whether the input htmlTd string matches the pattern or no. If it matches, the out params contain the link and name respectively.

/// <summary>
/// Assigns proper values to link and name, if the htmlId matches the pattern
/// </summary>
/// <returns>true if success, false otherwise</returns>
public static bool TryGetHrefDetails(string htmlTd, out string link, out string name)
{
    link = null;
    name = null;

    string pattern = "<td>\\s*<a\\s*href\\s*=\\s*(?:\"(?<link>[^\"]*)\"|(?<link>\\S+))\\s*>(?<name>.*)\\s*</a>\\s*</td>";

    if (Regex.IsMatch(htmlTd, pattern))
    {
        Regex r = new Regex(pattern,  RegexOptions.IgnoreCase | RegexOptions.Compiled);
        link = r.Match(htmlTd).Result("${link}");
        name = r.Match(htmlTd).Result("${name}");
        return true;
    }
    else
        return false;
}

I have tested this and it works correctly.

A CASE expression returns a value from the THEN portion of the clause. You could use it thusly:

SELECT  * 
FROM    sys.indexes i 
    JOIN sys.partitions p 
        ON i.index_id = p.index_id  
    JOIN sys.allocation_units a 
        ON CASE 
           WHEN a.type IN (1, 3) AND a.container_id = p.hobt_id THEN 1
           WHEN a.type IN (2) AND a.container_id = p.partition_id THEN 1
           ELSE 0
           END = 1

Note that you need to do something with the returned value, e.g. compare it to 1. Your statement attempted to return the value of an assignment or test for equality, neither of which make sense in the context of a CASE/THEN clause. (If BOOLEAN was a datatype then the test for equality would make sense.)

How about this:

times['days_since'] = max(list(df.index.values))  
times['days_since'] = times['days_since'] - times['months']  
times

OnClientClick seems to be very picky when used with OnClick.

I tried unsuccessfully with the following use cases:

OnClientClick="return ValidateSearch();" 
OnClientClick="if(ValidateSearch()) return true;"
OnClientClick="ValidateSearch();"

But they did not work. The following worked:

<asp:Button ID="keywordSearch" runat="server" Text="Search" TabIndex="1" 
  OnClick="keywordSearch_Click" 
  OnClientClick="if (!ValidateSearch()) { return false;};" />

If you think the space before and after "=" is mandatory, try it as separate item in the list.

Out = subprocess.Popen(['/usr/local/bin/script', 'hostname', '=', 'actual server name', '-p', 'LONGLIST'],shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)

You can also create a shortcut with an empty filename

"%LOCALAPPDATA%\Local\Code\Code.exe" ""

You can do this:

@Override
protected Dialog onCreateDialog(int id) {
    String messageDialog;
    String valueOK;
    String valueCancel;
    String titleDialog;
    switch (id) {

    case id:
        titleDialog = itemTitle;
        messageDialog = itemDescription
        valueOK = "OK";            
        return new AlertDialog.Builder(HomeView.this).setTitle(titleDialog).setPositiveButton(valueOK, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                Log.d(this.getClass().getName(), "AlertItem");
            }
        }).setMessage(messageDialog).create(); 

and then call to

showDialog(numbreOfItem);

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

In 2010 it is ctrl +k +d for indentation

I was able to figure it out. In case someone wants to know below the code that worked for me:

ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);

Let me know if there is a simpler way o doing it.

You should add maven-resources-plugin in your pom.xml file. Deleting ~/.m2/repository does not work always.

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.4</version>
            </plugin>
        </plugins>

Now build your project again. It should be successful!

• The reduce() method executes a provided function for each value of the array (from left-to-right).
• The return value of the function is stored in an accumulator (result/total).

It was ..

let array=[1,2,3];
function sum(acc,val){ return acc+val;} // => can change to (acc,val)=>acc+val
let answer= array.reduce(sum); // answer is 6

Change to

let array=[1,2,3];
let answer=arrays.reduce((acc,val)=>acc+val);

Also you can use in

1. find max

    let array=[5,4,19,2,7];
    function findMax(acc,val)
    {
     if(val>acc){
       acc=val; 
     }
    }

    let biggest=arrays.reduce(findMax); // 19

2. find an element that not repeated.

    arr = [1, 2, 5, 4, 6, 8, 9, 2, 1, 4, 5, 8, 9]
    v = 0
    for i in range(len(arr)):
    v = v ^ arr[i]
    print(value)  //6

Generically, do/while is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while or even a for loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:

do {
    char c = read_input();

    process_input(c);
} while (c != 'Q');

Update to Davids answer to even detect browsers that do not support pushstate:

if (history.pushState) {
  window.history.pushState("object or string", "Title", "/new-url");
} else {
  document.location.href = "/new-url";
}

get_or_create returns a tuple.

customer.source, created = Source.objects.get_or_create(name="Website")

if exist <insert file name here> (
    rem file exists
) else (
    rem file doesn't exist
)

Or on a single line (if only a single action needs to occur):

if exist <insert file name here> <action>

for example, this opens notepad on autoexec.bat, if the file exists:

if exist c:\autoexec.bat notepad c:\autoexec.bat

On my projects i give all rows the class "borders" which I want it to display more like a table with even borders. Giving each child element a border on the bottom and right and the first element of each row a left border will make all of your boxes have an even border:

First give all of the rows children a border on the right and bottom

.borders div{
    border-right:1px solid #999;
    border-bottom:1px solid #999;
}

Next give the first child of each or a left border

.borders div:first-child{
    border-left:
    1px solid #999;
}

Last make sure to clear the borders for their child elements

.borders div > div{
    border:0;
}

HTML:

<div class="row borders">
    <div class="col-xs-5 col-md-2">Email</div>
    <div class="col-xs-7 col-md-4">[email protected]</div>
    <div class="col-xs-5 col-md-2">Phone</div>
    <div class="col-xs-7 col-md-4">555-123-4567</div>
</div>

from your question I assume that you already have your data in hdfs. So you don't need to LOAD DATA, which moves the files to the default hive location /user/hive/warehouse. You can simply define the table using the externalkeyword, which leaves the files in place, but creates the table definition in the hive metastore. See here: Create Table DDL eg.:

create external table table_name (
  id int,
  myfields string
)
location '/my/location/in/hdfs';

Please note that the format you use might differ from the default (as mentioned by JigneshRawal in the comments). You can use your own delimiter, for example when using Sqoop:

row format delimited fields terminated by ','

In python "else if" is spelled "elif".
Also, you need a colon after the elif and the else.

Simple answer to a simple question. I had the same problem, when I first started (in the last couple of weeks).

So your code should read:

def function(a):
    if a == '1':
        print('1a')
    elif a == '2':
        print('2a')
    else:
        print('3a')

function(input('input:'))

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

You could use the Merge Functionality to achieve. Otherwise you can do:

declare @rowCount int

select @rowCount=@@RowCount

if @rowCount=0
begin
--insert....

You have to define public String toString() method in your Student class. For example:

public String toString() {
  return "Student: " + studentName + ", " + studentNo;
}

I found this question while googling for a way to auto-format phone numbers via a jQuery plugin. The accepted answer was not ideal for my needs and a lot has happened in the 6 years since it was originally posted. I eventually found the solution and am documenting it here for posterity.

Problem

I would like my phone number html input field to auto-format (mask) the value as the user types.

Solution

Check out Cleave.js. It is a very powerful/flexible and easy way to solve this problem, and many other data masking issues.

Formatting a phone number is as easy as:

var cleave = new Cleave('.input-element', {
    phone: true,
    phoneRegionCode: 'US'
});

If you just want to print user name on the pages, maybe you'll like this solution. It's free from object castings and works without Spring Security too:

@RequestMapping(value = "/index.html", method = RequestMethod.GET)
public ModelAndView indexView(HttpServletRequest request) {

    ModelAndView mv = new ModelAndView("index");

    String userName = "not logged in"; // Any default user  name
    Principal principal = request.getUserPrincipal();
    if (principal != null) {
        userName = principal.getName();
    }

    mv.addObject("username", userName);

    // By adding a little code (same way) you can check if user has any
    // roles you need, for example:

    boolean fAdmin = request.isUserInRole("ROLE_ADMIN");
    mv.addObject("isAdmin", fAdmin);

    return mv;
}

Note "HttpServletRequest request" parameter added.

Works fine because Spring injects it's own objects (wrappers) for HttpServletRequest, Principal etc., so you can use standard java methods to retrieve user information.

<button onclick="history.go(-1);">Back </button>

its very similar with nodejs

var User= require('./Users');

in this case its React:

import User from './User'

right now you can use

return (
      <Users></Users>
    )

{
  "number" : ["1","2","3"],
  "alphabet" : ["a", "b", "c"]
}

Related to the question in your answer:

You have multiple options to achieve this that are way better:

Let's assume you have a model which you pass to the view:

$model = Model::find(1);
View::make('view')->withModel($model);

Now in your Model you could have a function:

public function someFunction() {
    // do something
}

In your view you could call that function directly:

{{$model->someFunction()}}

This is nice if you want to do something with the model (the dataset).

If not you can still make a static function in the model:

public static function someStaticFunction($var1, $var2) {
    // do something
}

And then:

{{App\Model::someStaticFunction($yourVar1,$yourVar2)}}

Hope it helps.

meda's answer is completely legit, but when I copied the code I got an error!

Somewhere in the "php://input" there's an invalid character (maybe one of the quotes?).

When I typed the "php://input" code manually, it worked. Took me a while to figure out!

If you do not care about predictable run time you could try by first splitting your polygons into unions of convex polygons and then pairwise computing the intersection between the sub-polygons.

This would give you a collection of convex polygons such that their union is exactly the intersection of your starting polygons.

If you have the Adblock extension, make sure you add the domain into the exception list. I had that problem with Google Analytics

The difference is in the subsystem that each executable targets.

• java.exe targets the CONSOLE subsystem.
• javaw.exe targets the WINDOWS subsystem.

but I can't initialize my derived class, I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ?? so I'm thinking maybe in the PetStore default constructor I can call Farm()... so any Idea ???

Don't panic.

Farm constructor will be called in the constructor of PetStore, automatically.

See the base class inheritance calling rules: What are the rules for calling the superclass constructor?

Here are the built-in ways to do head and tail. Don't use pipes because if you have a large file, it will be extremely slow. Using these built-in options will be extremely fast even for huge files.

gc log.txt -head 10

gc log.txt -tail 10 -wait # equivalent to tail -f

An enum is nearly an integer. To simplify a lot

enum yourenum { a, b, c };

is almost like

#define a 0
#define b 1
#define c 2

Of course, it is not really true. I'm trying to explain that enum are some kind of coding...

You should definitely avoid using <jsp:...> tags. They're relics from the past and should always be avoided now.

Use the JSTL.

Now, wether you use the JSTL or any other tag library, accessing to a bean property needs your bean to have this property. A property is not a private instance variable. It's an information accessible via a public getter (and setter, if the property is writable). To access the questionPaperID property, you thus need to have a

public SomeType getQuestionPaperID() {
    //...
}

method in your bean.

Once you have that, you can display the value of this property using this code :

<c:out value="${Questions.questionPaperID}" />

or, to specifically target the session scoped attributes (in case of conflicts between scopes) :

<c:out value="${sessionScope.Questions.questionPaperID}" />

Finally, I encourage you to name scope attributes as Java variables : starting with a lowercase letter.

Sometime it is fixed by the Padding .. if you can play with that, then, it should fix your problem

<style type=text/css>

YourbuttonByID {Padding: 20px 80px; "for example" padding-left:50px; 
 padding-right:30px "to fix the text in the middle 
 without interfering with the text itself"}

</style>

It worked for me

Found solution on css-tricks

const element = document.getElementById('img')

element.classList.remove('classname'); // reset animation
void element.offsetWidth; // trigger reflow
element.classList.add('classname'); // start animation

Best of both worlds, use UIImage's drawAtPoint: or drawInRect: while still specifying your custom context:

UIGraphicsPushContext(context);
[image drawAtPoint:CGPointZero]; // UIImage will handle all especial cases!
UIGraphicsPopContext();

Also you avoid modifying your context with CGContextTranslateCTM or CGContextScaleCTM which the second answer does.

In my case, the error message referred to an old filename, which did no longer exist because it was renamed. It turned out that the outdated information did not come from the Makefile, but from files in .deps directories.

I ran into this error after copying files from one machine to another. In that process, I assume the timestamps got in an inconsistent state, which confused "make" when running multiple jobs in parallel (similar to this bug report).

Sequential builds with make -j 1 were not affected, but it took me a while to realize because I was using an alias (make -j 8).

To clean up the state, I removed all .deps files and regenerated the Makefile. These are the commands that I used:

find | grep '.deps' | xargs rm
find | grep '.deps' | xargs rmdir
autoreconf --install # (optional, but my project is using autotools) 
./configure

After that, building worked again.

The current lib.d.ts doesn't have promises in it defined so you need a extra definition file for it that is why you are getting compilation errors.

You could for example use (like @elclanrs says) use the es6-promise package with the definition file from DefinitelyTyped: es6-promise definition

You can then use it like this:

var p = new Promise<string>((resolve, reject) => { 
    resolve('a string'); 
});

edit You can use it without a definition when targeting ES6 (with the TypeScript compiler) - Note you still require the Promise to exists in the runtime ofcourse (so it won't work in old browsers :)) Add/Edit the following to your tsconfig.json :

"compilerOptions": {
    "target": "ES6"
}

edit 2 When TypeScript 2.0 will come out things will change a bit (though above still works) but definition files can be installed directly with npm like below:

npm install --save @types/es6-promise - source

edit3 Updating answer with more info for using the types.

Create a package.json file with only { } as the content (if you don't have a package.json already. Call npm install --save @types/es6-promise and tsc --init. The first npm install command will change your package.json to include the es6-promise as a dependency. tsc --init will create a tsconfig.json file for you.

You can now use the promise in your typescript file var x: Promise<any>;. Execute tsc -p . to compile your project. You should have no errors.

First, you run this command to delete your topic:

$ bin/kafka-topics.sh --delete --bootstrap-server localhost:9092 --topic <topic_name>

List active topics to check delete completely:

$ bin/kafka-topics.sh --list --bootstrap-server localhost:9092

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

You are right. Here is how write() method of BufferedWriter looks:

public void write(int c) throws IOException {
    synchronized (lock) {
        ensureOpen();
        if (nextChar >= nChars)
            flushBuffer();
        cb[nextChar++] = (char) c;
    }
}

As you can see it indeed checks whether the buffer is full (if (nextChar >= nChars)) and flushes the buffer. Then it adds new character to buffer (cb[nextChar++] = (char) c;).

Instead of comparing the dates directly, compare the getTime() value of the date. The getTime() function returns the number of milliseconds since Jan 1, 1970 as an integer-- should be trivial to determine if one integer falls between two other integers.

Something like

if((check.getTime() <= to.getTime() && check.getTime() >= from.getTime()))      alert("date contained");

If you want to go all fancy-pants, here's how you can extend it to be able to do this:

@(Html.ActionLink<ArticlesController>(x => x.Details(), article.Title, new { id = article.ArticleID }))

You will need to put this in the System.Web.Mvc namespace:

public static class MyProjectExtensions
{
    public static MvcHtmlString ActionLink<TController>(this HtmlHelper htmlHelper, Expression<Action<TController>> expression, string linkText)
    {
        var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext, htmlHelper.RouteCollection);

        var link = new TagBuilder("a");

        string actionName = ExpressionHelper.GetExpressionText(expression);
        string controllerName = typeof(TController).Name.Replace("Controller", "");

        link.MergeAttribute("href", urlHelper.Action(actionName, controllerName));
        link.SetInnerText(linkText);

        return new MvcHtmlString(link.ToString());
    }

    public static MvcHtmlString ActionLink<TController, TAction>(this HtmlHelper htmlHelper, Expression<Action<TController, TAction>> expression, string linkText, object routeValues)
    {
        var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext, htmlHelper.RouteCollection);

        var link = new TagBuilder("a");

        string actionName = ExpressionHelper.GetExpressionText(expression);
        string controllerName = typeof(TController).Name.Replace("Controller", "");

        link.MergeAttribute("href", urlHelper.Action(actionName, controllerName, routeValues));
        link.SetInnerText(linkText);

        return new MvcHtmlString(link.ToString());
    }

    public static MvcHtmlString ActionLink<TController>(this HtmlHelper htmlHelper, Expression<Action<TController>> expression, string linkText, object routeValues, object htmlAttributes) where TController : Controller
    {
        var urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext, htmlHelper.RouteCollection);

        var attributes = AnonymousObjectToKeyValue(htmlAttributes);

        var link = new TagBuilder("a");

        string actionName = ExpressionHelper.GetExpressionText(expression);
        string controllerName = typeof(TController).Name.Replace("Controller", "");

        link.MergeAttribute("href", urlHelper.Action(actionName, controllerName, routeValues));
        link.MergeAttributes(attributes, true);
        link.SetInnerText(linkText);

        return new MvcHtmlString(link.ToString());
    }

    private static Dictionary<string, object> AnonymousObjectToKeyValue(object anonymousObject)
    {
        var dictionary = new Dictionary<string, object>();

        if (anonymousObject == null) return dictionary;

        foreach (PropertyDescriptor propertyDescriptor in TypeDescriptor.GetProperties(anonymousObject))
        {
            dictionary.Add(propertyDescriptor.Name, propertyDescriptor.GetValue(anonymousObject));
        }

        return dictionary;
    }
}

This includes two overrides for Route Values and HTML Attributes, also, all of your views would need to add: @using YourProject.Controllers or you can add it to your web.config <pages><namespaces>

As long as you are aware of what you need to accomplish in the loop you could put the try catch outside the loop. But it is important to understand that the loop will then end as soon as the exception occurs and that may not always be what you want. This is actually a very common error in Java based software. People need to process a number of items, such as emptying a queue, and falsely rely on an outer try/catch statement handling all possible exceptions. They could also be handling only a specific exception inside the loop and not expect any other exception to occur. Then if an exception occurs that is not handled inside the loop then the loop will be "preemted", it ends possibly prematurely and the outer catch statement handles the exception.

If the loop had as its role in life to empty a queue then that loop very likely could end before that queue was really emptied. Very common fault.

You have to consider the Turkish I problem when comparing characters/ lowercasing / uppercasing:

I suggest to convert to String and use toLowerCase with invariant culture (in most cases at least).

public final static Locale InvariantLocale = new Locale(Empty, Empty, Empty); str.toLowerCase(InvariantLocale)

See similar C# string.ToLower() and string.ToLowerInvariant()

Note: Don't use String.equalsIgnoreCase http://nikolajlindberg.blogspot.co.il/2008/03/beware-of-java-comparing-turkish.html

Could the Barcode Rendering Framework at Codeplex GitHub be of help?

While there are no "official guidelines" I follow the principle of KISS and DRY. Make the overloaded constructors as simple as possible, and the simplest way is that they only call this(...). That way you only need to check and handle the parameters once and only once.

public class Simple {

    public Simple() {
        this(null);
    }

    public Simple(Resource r) {
        this(r, null);
    }

    public Simple(Resource r1, Resource r2) {
        // Guard statements, initialize resources or throw exceptions if
        // the resources are wrong
        if (r1 == null) {
            r1 = new Resource();
        }
        if (r2 == null) {
            r2 = new Resource();
        }

        // do whatever with resources
    }

}

From a unit testing standpoint, it'll become easy to test the class since you can put in the resources into it. If the class has many resources (or collaborators as some OO-geeks call it), consider one of these two things:

Make a parameter class

public class SimpleParams {
    Resource r1;
    Resource r2;
    // Imagine there are setters and getters here but I'm too lazy 
    // to write it out. you can make it the parameter class 
    // "immutable" if you don't have setters and only set the 
    // resources through the SimpleParams constructor
}

The constructor in Simple only either needs to split the SimpleParams parameter:

public Simple(SimpleParams params) {
    this(params.getR1(), params.getR2());
}

…or make SimpleParams an attribute:

public Simple(Resource r1, Resource r2) {
    this(new SimpleParams(r1, r2));
}

public Simple(SimpleParams params) {
    this.params = params;
}

Make a factory class

Make a factory class that initializes the resources for you, which is favorable if initializing the resources is a bit difficult:

public interface ResourceFactory {
    public Resource createR1();
    public Resource createR2();
}

The constructor is then done in the same manner as with the parameter class:

public Simple(ResourceFactory factory) {
    this(factory.createR1(), factory.createR2());
} 

Make a combination of both

Yeah... you can mix and match both ways depending on what is easier for you at the time. Parameter classes and simple factory classes are pretty much the same thing considering the Simple class that they're used the same way.

I found the cleanest way of doing it is this.

Tested on Django 3.1.5

class MyForm(forms.Form):
    my_boolean = forms.BooleanField(required=False, initial=True)

I found the answer here

1st download jquery.form.js file from below url

Write below code in cshtml

The answer by @sbk is the way we should do it in spring-boot environment (apart from @Value("${classpath*:})), in my opinion. But in my scenario it was not working if the execute from standalone jar..may be I did something wrong.

But this can be another way of doing this,

InputStream is = this.getClass().getClassLoader().getResourceAsStream(<relative path of the resource from resource directory>);

Hope this helps. From eclipse, you right click the project -> Run As -> Run on Server and then it worked for me. I used Eclipse Jee Neon and Apache Tomcat 9.0. :)

I just removed the head portion in index.html file and it worked fine.This is the head tag in html file

Try this:

CASE WHEN table3.col3 IS NULL THEN table2.col3 ELSE table3.col3 END as col4

The as col4 should go at the end of the CASE the statement. Also note that you're missing the END too.

Another probably more simple option would be:

IIf([table3.col3] Is Null,[table2.col3],[table3.col3])

Just to clarify, MS Access does not support COALESCE. If it would that would be the best way to go.

Edit after radical question change:

To turn the query into SQL Server then you can use COALESCE (so it was technically answered before too):

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
COALESCE(dbo.EU_Admin3.EUID, dbo.EU_Admin2.EUID)
FROM dbo.AdminID

BTW, your CASE statement was missing a , before the field. That's why it didn't work.

Use .isBool in your String value. It work for me

your_string.isBool

If you're still getting a env: ruby_executable_hooks: No such file or directory when calling some Ruby package, that means RVM left a little gift for you in your $PATH.

Run the following to find the offending scripts:

grep '#!/usr/bin/env ruby_executable_hooks' /usr/local/bin/*

Then rm all the matches. You'll have to reinstall all of those libraries with an RVM-free gem, of course.

NoneType is simply the type of the None singleton:

>>> type(None)
<type 'NoneType'>

From the latter link above:

None

The sole value of the type NoneType. None is frequently used to represent the absence of a value, as when default arguments are not passed to a function. Assignments to None are illegal and raise a SyntaxError.

In your case, it looks like one of the items you are trying to concatenate is None, hence your error.

1. The input tag doesn't have onsubmit handler. Instead, you should put your onsubmit handler on actual form tag, like this:
   
   <form name="loginform" onsubmit="validateForm()" method="post">
   
   Here are some useful links:

   • JavaScript Form Validation
   • Form onsubmit Event

2. For the form tag you can specify the request method, GET or POST. By default, the method is GET. One of the differences between them is that in case of GET method, the parameters are appended to the URL (just what you have shown), while in case of POST method there are not shown in URL.

   You can read more about the differences here.

UPDATE:

You should return the function call and also you can specify the URL in action attribute of form tag. So here is the updated code:

<form name="loginform" onSubmit="return validateForm();" action="main.html" method="post">
    <label>User name</label>
    <input type="text" name="usr" placeholder="username"> 
    <label>Password</label>
    <input type="password" name="pword" placeholder="password">
    <input type="submit" value="Login"/>
</form>

<script>
    function validateForm() {
        var un = document.loginform.usr.value;
        var pw = document.loginform.pword.value;
        var username = "username"; 
        var password = "password";
        if ((un == username) && (pw == password)) {
            return true;
        }
        else {
            alert ("Login was unsuccessful, please check your username and password");
            return false;
        }
  }
</script>

To round up you can use modulus.

The second part of the equation will add to True if there's a remainder. (True = 1; False = 0)

ex: 3/2

answer=$(((3 / 2) + (3 % 2 > 0)))
echo $answer
2

ex: 100 / 2

answer=$(((100 / 2) + (100 % 2 > 0)))
echo $answer
50

ex: 100 / 3

answer=$(((100 / 3) + (100 % 3 > 0)))
echo $answer
34

Move DropDownList1.Items.Add(new ListItem("Select", "0", true)); After bindStatusDropDownList();

so:

    if (!IsPostBack)
    {
        bindStatusDropDownList(); //first create structure
        DropDownList1.Items.Add(new ListItem("Select", "0", true)); // after add item
    }

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

diff can not only compare two files, it can, by using the -r option, walk entire directory trees, recursively checking differences between subdirectories and files that occur at comparable points in each tree.

$ man diff

...

-r  --recursive
        Recursively compare any subdirectories found.

...

You can use <pre> tags as I did in one of my projects.

To escape it, double the quotes:

INSERT INTO TABLE_A VALUES ( 'Alex''s Tea Factory' );

Using Hex in Apache Commons:

String hexString = "fd00000aa8660b5b010006acdc0100000101000100010000";    
byte[] bytes = Hex.decodeHex(hexString.toCharArray());
System.out.println(new String(bytes, "UTF-8"));

One last thing is to check for Event Listeners > "scroll" and test deleting them.

Even if you delete the Javascript that created them, the listeners will stick around and prevent scrolling.

I don't really understand the full scope of your question, but if all you need is a hash of the string, then it's very easy to get that.

Just use the GetHashCode method.

Like this:

string hash = username.GetHashCode();

Your class JSON_result does not match your JSON string. Note how the object JSON_result is going to represent is wrapped in another property named "Venue".

So either create a class for that, e.g.:

Public Class Container
    Public Venue As JSON_result
End Class

Public Class JSON_result
    Public ID As Integer
    Public Name As String
    Public NameWithTown As String
    Public NameWithDestination As String
    Public ListingType As String
End Class

Dim obj = JsonConvert.DeserializeObject(Of Container)(...your_json...)

or change your JSON string to

{
    "ID": 3145,
    "Name": "Big Venue, Clapton",
    "NameWithTown": "Big Venue, Clapton, London",
    "NameWithDestination": "Big Venue, Clapton, London",
    "ListingType": "A",
    "Address": {
        "Address1": "Clapton Raod",
        "Address2": "",
        "Town": "Clapton",
        "County": "Greater London",
        "Postcode": "PO1 1ST",
        "Country": "United Kingdom",
        "Region": "Europe"
    },
    "ResponseStatus": {
        "ErrorCode": "200",
        "Message": "OK"
    }
}

or use e.g. a ContractResolver to parse the JSON string.

int var1 = int.Parse(ds.Tables[0].Rows[0][3].ToString());
int var2 = int.Parse(ds.Tables[0].Rows[0][4].ToString());

In Spring 4.2+ you can now simply do:

@Component
class StartupHousekeeper {

    @EventListener(ContextRefreshedEvent.class)
    public void contextRefreshedEvent() {
        //do whatever
    }
}

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

Bash can get the last part of a path without having to call the external basename:

subdir="/path/to/whatever/${1##*/}"

Check out copyOfRange; and example:

int[] arr2 = Arrays.copyOfRange(arr,0,3);

You have to add the two modified files to the index before git will recognize it as a move.

The only difference between mv old new and git mv old new is that the git mv also adds the files to the index.

mv old new then git add -A would have worked, too.

Note that you can't just use git add . because that doesn't add removals to the index.

See Difference between "git add -A" and "git add ."

i am currently working on this and planning on releasing it as a jQuery-ui plugin.

-> http://coulisse.luvdasun.com/

please let me know if you are interested and what you are hoping to see in such a plugin.

gr

A bit too late, but this solution is nice and neat

const arr = [[1,2,3],[4,5,6],[7,8,9,10]]
for (let i of arr) {
  for (let j of i) {
    console.log(j) //Should log numbers from 1 to 10
  }
}

Or in your case:

const arr = [[1,2,3],[4,5,6],[7,8,9]]
for (let [d1, d2, d3] of arr) {
  console.log(`${d1}, ${d2}, ${d3}`) //Should return numbers from 1 to 9
}

Note: for ... of loop is standardised in ES6, so only use this if you have an ES5 Javascript Complier (such as Babel)

Another note: There are alternatives, but they have some subtle differences and behaviours, such as forEach(), for...in, for...of and traditional for(). It depends on your case to decide which one to use. (ES6 also has .map(), .filter(), .find(), .reduce())

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

Fix answer Rob Dickerson.

It's easier to use:

public static String join(String delimiter, String... values)
{
    StringBuilder stringBuilder = new StringBuilder();

    for (String value : values)
    {
        stringBuilder.append(value);
        stringBuilder.append(delimiter);
    }

    String result = stringBuilder.toString();

    return result.isEmpty() ? result : result.substring(0, result.length() - 1);
}

This would do

string x = TextBoxD1.Text;
int xi = Convert.ToInt32(x);

Or you can use

int xi = Int32.Parse(x);

Refer Microsoft Developer Network for more information

Finally i thought my way is better since when number of return types go higher this kind of a implementation do that in best way.

public static ReturningValues myMethod() {
ReturningValues rv = new ReturningValues();
rv.setValue("value");
rv.setIndex(12);
return rv;
}

There are many examples and also of different types for logging. Take a look at the java.util.logging package.

Example code:

import java.util.logging.Logger;

public class Main {

  private static Logger LOGGER = Logger.getLogger("InfoLogging");

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

Without hard-coding the class name:

import java.util.logging.Logger;

public class Main {
  private static final Logger LOGGER = Logger.getLogger(
    Thread.currentThread().getStackTrace()[0].getClassName() );

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

Capture the PID of the ngnix process in a variable (for example $NGNIX_PID) and at the end of the entrypoint file do

wait $NGNIX_PID 

In that way, your container should run until ngnix is alive, when ngnix stops, the container stops as well

I thought I could do that, but quite disappointed: it doesn't work, but I think it still worths sharing.

Maybe someone can correct:

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;

interface SomeContainer<E> {
    E createContents();
}

public class Main {

    @SuppressWarnings("unchecked")
    public static <E> SomeContainer<E> createSomeContainer() {
        return (SomeContainer<E>) Proxy.newProxyInstance(Main.class.getClassLoader(),
                new Class[]{ SomeContainer.class }, new InvocationHandler() {
            @Override
            public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
                Class<?> returnType = method.getReturnType();
                return returnType.newInstance();
            }
        });
    }

    public static void main(String[] args) {
        SomeContainer<String> container = createSomeContainer();

    [*] System.out.println("String created: [" +container.createContents()+"]");

    }
}

It produces:

Exception in thread "main" java.lang.ClassCastException: java.lang.Object cannot be cast to java.lang.String
    at Main.main(Main.java:26)

Line 26 is the one with the [*].

The only viable solution is the one by @JustinRudd

but it's not working in IE. recommend using :nth-child(2n+1) :nth-child(2n+2)

li {_x000D_
    color: black;_x000D_
}_x000D_
li:nth-child(odd) {_x000D_
    color: #777;_x000D_
}_x000D_
li:nth-child(even) {_x000D_
    color: blue;_x000D_
}

<ul>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
    <li>ho</li>_x000D_
</ul>

The best practice is use safe typing, I recommend you:

interface customObject extends MyObject {
   newProp: string;
   newProp2: number;
}

\path-to-your-android-sdk-folder\platforms\android-xx\data\res

sklearn.cross_validation is deprecated since version 0.18, instead you should use sklearn.model_selection as show below

from sklearn.model_selection import train_test_split
import numpy

with open("datafile.txt", "rb") as f:
   data = f.read().split('\n')
   data = numpy.array(data)  #convert array to numpy type array

   x_train ,x_test = train_test_split(data,test_size=0.5)       #test_size=0.5(whole_data)

The two includes you mention in your comment are essential. 'does not name a type' just means there is no definition for that identifier visible to the compiler. If there are errors in the LCD library you mention, then those need to be addressed - omitting the #include will definitely not fix it!

Two notes from experience which might be helpful:

1. You need to add all #include's to the main sketch - irrespective of whether they are included via another #include.

2. If you add files to the library folder, the Arduino IDE must be restarted before those new files will be visible.

A few principles:

1. you have a std::exception base class, you should have your exceptions derive from it. That way general exception handler still have some information.

2. Don't throw pointers but object, that way memory is handled for you.

Example:

struct MyException : public std::exception
{
   std::string s;
   MyException(std::string ss) : s(ss) {}
   ~MyException() throw () {} // Updated
   const char* what() const throw() { return s.c_str(); }
};

And then use it in your code:

void Foo::Bar(){
  if(!QueryPerformanceTimer(&m_baz)){
    throw MyException("it's the end of the world!");
  }
}

void Foo::Caller(){
  try{
    this->Bar();// should throw
  }catch(MyException& caught){
    std::cout<<"Got "<<caught.what()<<std::endl;
  }
}

My quick solution was to close all opened files in text editor area and then reopen them again from Solution Explorer.

If you have a ConstraintLayout with some size, and a child View with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"

or

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

Because the view is smaller, these constraints are impossible. But ConstraintLayout will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.

This concept works with any target view, not just the parent.

Update

Below is XML that achieves your desired UI with no nesting of views and no Guidelines (though guidelines are not inherently evil).

DB to C#

EnumDisplayStatus status = (EnumDisplayStatus)int.Parse(GetValueFromDb());

C# to DB

string dbStatus = ((int)status).ToString();

WARNING: This solution has security risks.

Try running the container as privileged:

sudo docker run --privileged=true -i -v /data1/Downloads:/Downloads ubuntu bash

Another option (that I have not tried) would be to create a privileged container and then create non-privileged containers inside of it.

This may be due to version incompatibility between your code and the version you have installed.

In my case I was using v8.12.0 for development (locally) and installed latest version v13.7.0 on the server.

So using nvm I switched the node version to v8.12.0 with the below command:

> nvm install 8.12.0 // to install the version I wanted

> nvm use 8.12.0  // use the installed version

NOTE: You need to install nvm on your system to use nvm.

You should try this solution before trying solutions like installing build-essentials or uninstalling the current node version because you could switch between versions easily than reverting all the installations/uninstallations that you've done.

It's not that your file is partially downloaded. It fails authentication and hence downloads e.g "index.html" but it names it myfile.zip (since this is what you want to download).

I followed the link suggested by @thomasbabuj and figured it out eventually.

You should try adding --auth-no-challenge and as @thomasbabuj suggested replace your password entry

I.e

wget --auth-no-challenge --user=myusername --ask-password https://test.mydomain.com/files/myfile.zip

To achieve this you can try below steps:

1. Copy the cell or column which has the conditional formatting you want to copy.
2. Go to the desired cell or column (maybe other sheets) where you want to apply conditional formatting.
3. Open the context menu of the desired cell or column (by right-click on it).
4. Find the "Paste Special" option which has a sub-menu.
5. Select the "Paste conditional formatting only" option of the sub-menu and done.

You could use ng-init in an outer div:

<div ng-init="param='value';">
    <div ng-controller="BasketController" >
        <label>param: {{value}}</label>
    </div>
</div>  

The parameter will then be available in your controller's scope:

function BasketController($scope) {
        console.log($scope.param);
}

SapphireSun is quite right. You can just use lst.sort(). Python's sort implementation (TimSort) check if the list is already sorted. If so sort() will completed in linear time. Sounds like a Pythonic way to ensure a list is sorted ;)

Check if a MySQL connection is open

ConnectionState state = connection.State;
if (state == ConnectionState.Open)
{
    return true;
}
else
{
    connection.Open();
    return true;
}

Here is another library.

Changes required are -

1. Add sorttable js
   

2. Add class name sortable to table.

Click the table headers to sort the table accordingly:

<script src="https://www.kryogenix.org/code/browser/sorttable/sorttable.js"></script>

<table class="sortable">
  <tr>
    <th>Name</th>
    <th>Address</th>
    <th>Sales Person</th>
  </tr>

  <tr class="item">
    <td>user:0001</td>
    <td>UK</td>
    <td>Melissa</td>
  </tr>
  <tr class="item">
    <td>user:0002</td>
    <td>France</td>
    <td>Justin</td>
  </tr>
  <tr class="item">
    <td>user:0003</td>
    <td>San Francisco</td>
    <td>Judy</td>
  </tr>
  <tr class="item">
    <td>user:0004</td>
    <td>Canada</td>
    <td>Skipper</td>
  </tr>
  <tr class="item">
    <td>user:0005</td>
    <td>Christchurch</td>
    <td>Alex</td>
  </tr>

</table>

You are correct, I think the [0,len(xs)] is throwing you off. You'll want to reuse the original x-axis variable xs and plot that with another numpy array of the same length that has your variable in it.

annual = np.arange(1,21,1)
l = np.array(value_list) # a list with 20 values
spl = UnivariateSpline(annual,l)
xs = np.linspace(1,21,200)
plt.plot(xs,spl(xs),'b')

#####horizontal line
horiz_line_data = np.array([40 for i in xrange(len(xs))])
plt.plot(xs, horiz_line_data, 'r--') 
###########plt.plot([0,len(xs)],[40,40],'r--',lw=2)
pylab.ylim([0,200])
plt.show()

Hopefully that fixes the problem!

As of C++17:

Make sure you include std filesystem.

#include <filesystem>

and now you can do this.

std::filesystem::current_path().string()

boost filesystem became part of the standard lib.

if you can't find it try to look under:

std::experimental::filesystem

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

As an alternative to James McNellis answer, I always try to use enumeration for the bool type instead of macros: typedef enum bool {false=0; true=1;} bool;. It is safer b/c it lets the compiler do type checking and eliminates macro expansion races

Reading PDF files from a directory:

var list = Directory.GetFiles(@"C:\ScanPDF", "*.pdf");
if (list.Length > 0)
{

}

Try the following instead:

<html>
 <head>
  <title>Table row styling</title>
  <style type="text/css">
    .bb td, .bb th {
     border-bottom: 1px solid black !important;
    }
  </style>
 </head>
 <body>
  <table>
    <tr class="bb">
      <td>This</td>
      <td>should</td>
      <td>work</td>
    </tr>
  </table>
 </body>
</html>

you could use a cursor:

DECLARE @id int
DECLARE @pass varchar(100)

DECLARE cur CURSOR FOR SELECT Id, Password FROM @temp
OPEN cur

FETCH NEXT FROM cur INTO @id, @pass

WHILE @@FETCH_STATUS = 0 BEGIN
    EXEC mysp @id, @pass ... -- call your sp here
    FETCH NEXT FROM cur INTO @id, @pass
END

CLOSE cur    
DEALLOCATE cur

Enabling TLS 1.0 solved our issues as well (after disabling SSL v3). (Server 2012 R2 with ASP.net 4.0 website processing against PPI pay services). This is the RegEdit script I used to set everything the way I wanted. We only disabled SSL v3 for the Client and not the server as doing that broke other things that we were not ready to deal with yet. After we upgrade the site to .Net 4.5.2 then we will disable TLS 1.0 again.

This script enables all protocols, Server and Client except for SSL v3 for the Client.

Yes, you can by using DBlink (postgresql only) and DBI-Link (allows foreign cross database queriers) and TDS_LInk which allows queries to be run against MS SQL server.

I have used DB-Link and TDS-link before with great success.

On http://www.labnol.org/internet/tools/short-urls-for-google-maps/6604/ they show a short URL that works pretty well

Google Maps URLs are pretty unwieldy especially when sending over an IM, tweet or email. MapOf.it provides you a quick way to link to Google Maps by simply specifying the address of the location as a search parameter.

I used it for a few applications I've designed and it worked like a charm.

Short Summary

Active Directory is a directory services implemented by Microsoft, and it supports Lightweight Directory Access Protocol (LDAP).

Long Answer

Firstly, one needs to know what's Directory Service.

Directory Service is a software system that stores, organises, and provides access to information in a computer operating system's directory. In software engineering, a directory is a map between names and values. It allows the lookup of named values, similar to a dictionary.

For more details, read https://en.wikipedia.org/wiki/Directory_service

Secondly,as one could imagine, different vendors implement all kinds of forms of directory service, which is harmful to multi-vendor interoperability.

Thirdly, so in the 1980s, the ITU and ISO came up with a set of standards - X.500, for directory services, initially to support the requirements of inter-carrier electronic messaging and network name lookup.

Fourthly, so based on this standard, Lightweight Directory Access Protocol, LDAP, is developed. It uses the TCP/IP stack and a string encoding scheme of the X.500 Directory Access Protocol (DAP), giving it more relevance on the Internet.

Lastly, based on this LDAP/X.500 stack, Microsoft implemented a modern directory service for Windows, originating from the X.500 directory, created for use in Exchange Server. And this implementation is called Active Directory.

So in a short summary, Active Directory is a directory services implemented by Microsoft, and it supports Lightweight Directory Access Protocol (LDAP).

PS[0]: This answer heavily copies content from the wikipedia page listed above.

PS[1]: To know why it may be better use directory service rather just using a relational database, read https://en.wikipedia.org/wiki/Directory_service#Comparison_with_relational_databases

or you can simply use

def question_params

  params.require(:question).permit(team_ids: [])

end

In case that you define your route like the one asked in the question (path: '/link/to/page'):

import Vue from 'vue'
import Router from 'vue-router'
import MyComponent from '@/components/MyComponent.vue';

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/link/to/page',
      component: MyComponent
    }
  ]
})

You can resolve the URL in your summary page and open your sub page as below:

<script>
export default {
  methods: {
    popup() {
      let route = this.$router.resolve({path: '/link/to/page'});
      // let route = this.$router.resolve('/link/to/page'); // This also works.
      window.open(route.href, '_blank');
    }
  }
};
</script>

Of course if you've given your route a name, you can resolve the URL by name:

routes: [
  {
    path: '/link/to/page',
    component: MyComponent,
    name: 'subPage'
  }
]

...

let route = this.$router.resolve({name: 'subPage'});

• vue-router router.resolve(location, current?, append?)
• vue-router router-link

I tested bits and pieces of the following, but not the complete rule set in its entirety, so if you run into trouble with it let me know and I'll dig around a bit more. However, assuming I got everything correct, you could try something like the following:

RewriteEngine On

# Check if this is the noredirect query string
RewriteCond %{QUERY_STRING} (^|&)noredirect=true(&|$)
# Set a cookie, and skip the next rule
RewriteRule ^ - [CO=mredir:0:%{HTTP_HOST},S]

# Check if this looks like a mobile device
# (You could add another [OR] to the second one and add in what you
#  had to check, but I believe most mobile devices should send at
#  least one of these headers)
RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
RewriteCond %{HTTP:Profile}       !^$
# Check if we're not already on the mobile site
RewriteCond %{HTTP_HOST}          !^m\.
# Check to make sure we haven't set the cookie before
RewriteCond %{HTTP:Cookie}        !\smredir=0(;|$)
# Now redirect to the mobile site
RewriteRule ^ http://m.example.org%{REQUEST_URI} [R,L]

You are accessing an object that is not defined.

The solution is check for null or undefined (to see whether the object exists) and only then iterate.

This worked for me for cardView and will work the same for listview inside adapter calss, within onBindViewHolder() function

holder.cardView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                return false;
            }
        });

xlrd.xldate_as_tuple is nice, but there's xlrd.xldate.xldate_as_datetime that converts to datetime as well.

import xlrd
wb = xlrd.open_workbook(filename)
xlrd.xldate.xldate_as_datetime(41889, wb.datemode)
=> datetime.datetime(2014, 9, 7, 0, 0)

Formatter will work fine in this case.

import org.apache.poi.ss.usermodel.DataFormatter;

FileInputStream fis = new FileInputStream(workbookName);
Workbook workbook = WorkbookFactory.create(fis);
Sheet sheet = workbook.getSheet(sheetName);
DataFormatter formatter = new DataFormatter();
String val = formatter.formatCellValue(sheet.getRow(row).getCell(col));
list.add(val);   //Adding value to list

Here is what I had and what caused my "incomplete type error":

#include "X.h" // another already declared class
class Big {...} // full declaration of class A

class Small : Big {
    Small() {}
    Small(X); // line 6
}
//.... all other stuff

What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..

Big.cpp

Small::Big(X my_x) { // line 9 <--- LOOK at this !
}

I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..

Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.

One option is to use regular expressions:

if (str.match("^Hello")) {
   // do this if begins with Hello
}

if (str.match("World$")) {
   // do this if ends in world
}

I'm still getting my feet wet with Node.js, but I have a few ideas. first, I believe you need to use execFile instead of spawn; execFile is for when you have the path to a script, whereas spawn is for executing a well-known command that Node.js can resolve against your system path.

1. Provide a callback to process the buffered output:

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], function(err, stdout, stderr) { 
    // Node.js will invoke this callback when process terminates.
    console.log(stdout); 
});  

2. Add a listener to the child process' stdout stream (9thport.net)

var child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3' ]); 
// use event hooks to provide a callback to execute when data are available: 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

Further, there appear to be options whereby you can detach the spawned process from Node's controlling terminal, which would allow it to run asynchronously. I haven't tested this yet, but there are examples in the API docs that go something like this:

child = require('child_process').execFile('path/to/script', [ 
    'arg1', 'arg2', 'arg3', 
], { 
    // detachment and ignored stdin are the key here: 
    detached: true, 
    stdio: [ 'ignore', 1, 2 ]
}); 
// and unref() somehow disentangles the child's event loop from the parent's: 
child.unref(); 
child.stdout.on('data', function(data) {
    console.log(data.toString()); 
});

For more complex layouts I often used GridBagLayout, which is more complex, but that's the price. Today, I would probably check out MiGLayout.

The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.

<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>

Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.

<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>

When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.

Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>

I had a related issue when migrating from a CE db over to Sql Server on Azure. Just wasted 4 hrs trying to solve this. Hopefully this may save someone a similar fate. For me, I had a reference to SqlCE in my packages.config file. Removing it solved my entire issue and allowed me to use migrations. Yay Microsoft for another tech with unnecessarily complex setup and config issues.

With a quick Googling I found this... Does that work for you?

If all gone well, you should be able to get the following result;

Hi user_name! You've successfully authenticated,...

Solution who works with Lumen 5.5 with foreign keys constraints :

$categories = MusicCategory::all();
foreach($categories as $category)
{
$category->delete();

}
return response()->json(['error' => false]);

Use a lambda function.

Let's say you have an array:

nums = [0,1,5]

Check whether 5 is in nums in Python 3.X:

(len(list(filter (lambda x : x == 5, nums))) > 0)

Check whether 5 is in nums in Python 2.7:

(len(filter (lambda x : x == 5, nums)) > 0)

This solution is more robust. You can now check whether any number satisfying a certain condition is in your array nums.

For example, check whether any number that is greater than or equal to 5 exists in nums:

(len(filter (lambda x : x >= 5, nums)) > 0)

select max(Salary) from EmployeeTest where Salary < ( select max(Salary) from EmployeeTest ) ;

this will work for all DBs.

for frequency distribution of a variable with excessive values you can collapse down the values in classes,

Here I excessive values for employrate variable, and there's no meaning of it's frequency distribution with direct values_count(normalize=True)

                country  employrate alcconsumption
0           Afghanistan   55.700001            .03
1               Albania   11.000000           7.29
2               Algeria   11.000000            .69
3               Andorra         nan          10.17
4                Angola   75.699997           5.57
..                  ...         ...            ...
208             Vietnam   71.000000           3.91
209  West Bank and Gaza   32.000000               
210         Yemen, Rep.   39.000000             .2
211              Zambia   61.000000           3.56
212            Zimbabwe   66.800003           4.96

[213 rows x 3 columns]

frequency distribution with values_count(normalize=True) with no classification,length of result here is 139 (seems meaningless as a frequency distribution):

print(gm["employrate"].value_counts(sort=False,normalize=True))

50.500000   0.005618
61.500000   0.016854
46.000000   0.011236
64.500000   0.005618
63.500000   0.005618

58.599998   0.005618
63.799999   0.011236
63.200001   0.005618
65.599998   0.005618
68.300003   0.005618
Name: employrate, Length: 139, dtype: float64

putting classification we put all values with a certain range ie.

0-10 as 1,
11-20 as 2  
21-30 as 3, and so forth.

gm["employrate"]=gm["employrate"].str.strip().dropna()  
gm["employrate"]=pd.to_numeric(gm["employrate"])
gm['employrate'] = np.where(
   (gm['employrate'] <=10) & (gm['employrate'] > 0) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=20) & (gm['employrate'] > 10) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=30) & (gm['employrate'] > 20) , 2, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=40) & (gm['employrate'] > 30) , 3, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=50) & (gm['employrate'] > 40) , 4, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=60) & (gm['employrate'] > 50) , 5, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=70) & (gm['employrate'] > 60) , 6, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=80) & (gm['employrate'] > 70) , 7, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=90) & (gm['employrate'] > 80) , 8, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=100) & (gm['employrate'] > 90) , 9, gm['employrate']
   )
print(gm["employrate"].value_counts(sort=False,normalize=True))

after classification we have a clear frequency distribution. here we can easily see, that 37.64% of countries have employ rate between 51-60% and 11.79% of countries have employ rate between 71-80%

5.000000   0.376404
7.000000   0.117978
4.000000   0.179775
6.000000   0.264045
8.000000   0.033708
3.000000   0.028090
Name: employrate, dtype: float64

You can call a non static method within a static one using: Classname.class.method()

This works for me in IE 10 and FF 23

<input type="text" size="100" />

Short answer for the code in question is:

UPDATE `table` SET test=number

Here table is the table name and it's surrounded by grave accent (aka back-ticks `) as this is MySQL convention to escape keywords (and TABLE is a keyword in that case).

BEWARE, that this is pretty dangerous query which will wipe everything in column test in every row of your table replacing it by the number (regardless of it's value)

It is more common to use WHERE clause to limit your query to only specific set of rows:

UPDATE `products` SET `in_stock` = true WHERE `supplier_id` = 10

Yes, Range :

The range form of the for loop iterates over a slice or map.

When ranging over a slice, two values are returned for each iteration. The first is the index, and the second is a copy of the element at that index.

Example :

package main

import "fmt"

var pow = []int{1, 2, 4, 8, 16, 32, 64, 128}

func main() {
    for i, v := range pow {
        fmt.Printf("2**%d = %d\n", i, v)
    }

    for i := range pow {
        pow[i] = 1 << uint(i) // == 2**i
    }
    for _, value := range pow {
        fmt.Printf("%d\n", value)
    }
}

• You can skip the index or value by assigning to _.
• If you only want the index, drop the , value entirely.

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.

<ComboBox ItemsSource="{Binding SalesPeriods}" 
          SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />

Use the ajax object's beforeSend and complete functions. It's better to show the gif from inside beforeSend so that all the behavior is encapsulated in a single object. Be careful about hiding the gif using the success function. If the request fails, you'll probably still want to hide the gif. To do this use the Complete function. It would look like this:

$.ajax({
    url: uri,
    cache: false,
    beforeSend: function(){
        $('#image').show();
    },
    complete: function(){
        $('#image').hide();
    },
    success: function(html){
       $('.info').append(html);
    }
});

Another relatively simple way is using Object.keys. This returns an array which means you get all of the features of an array.

var noInfo = {};
var info = {something: 'data'};

Object.keys(noInfo).length //returns 0 or false
Object.keys(info).length //returns 1 or true

Although we are in a world with great browser support. Because this question is so old I thought I'd add this: This is safe to use as of JavaScript v1.8.5.

** Problem Solved ** // Changed to delegate() method to use delegation from the body

$("body").delegate("#boundOnPageLoaded", "click", function(){

});

Use purrr::has_element to check against the value of a list element:

> x <- list(c(1, 2), c(3, 4))
> purrr::has_element(x, c(3, 4))
[1] TRUE
> purrr::has_element(x, c(3, 5))
[1] FALSE

For Java 8 and above, it's easy:

when(mock.process(Matchers.anyList()));

For Java 7 and below, the compiler needs a bit of help. Use anyListOf(Class<T> clazz):

when(mock.process(Matchers.anyListOf(Bar.class)));

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

You could do it easily with an extension function rather than a regex ...

public static bool IsAlphaNum(this string str)
{
    if (string.IsNullOrEmpty(str))
        return false;

    for (int i = 0; i < str.Length; i++)
    {
        if (!(char.IsLetter(str[i])) && (!(char.IsNumber(str[i]))))
            return false;
    }

    return true;
}

Per comment :) ...

public static bool IsAlphaNum(this string str)
{
    if (string.IsNullOrEmpty(str))
        return false;

    return (str.ToCharArray().All(c => Char.IsLetter(c) || Char.IsNumber(c)));
}

WIth the Help of @excray's comment, I manage to figure it out the answer, What we need to do is actually write a simple for loop to iterate over the two arrays that represent the train data and test data.

First implement a simple lambda function to hold formula for the cosine calculation:

cosine_function = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

And then just write a simple for loop to iterate over the to vector, logic is for every "For each vector in trainVectorizerArray, you have to find the cosine similarity with the vector in testVectorizerArray."

from sklearn.feature_extraction.text import CountVectorizer
from sklearn.feature_extraction.text import TfidfTransformer
from nltk.corpus import stopwords
import numpy as np
import numpy.linalg as LA

train_set = ["The sky is blue.", "The sun is bright."] #Documents
test_set = ["The sun in the sky is bright."] #Query
stopWords = stopwords.words('english')

vectorizer = CountVectorizer(stop_words = stopWords)
#print vectorizer
transformer = TfidfTransformer()
#print transformer

trainVectorizerArray = vectorizer.fit_transform(train_set).toarray()
testVectorizerArray = vectorizer.transform(test_set).toarray()
print 'Fit Vectorizer to train set', trainVectorizerArray
print 'Transform Vectorizer to test set', testVectorizerArray
cx = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)

for vector in trainVectorizerArray:
    print vector
    for testV in testVectorizerArray:
        print testV
        cosine = cx(vector, testV)
        print cosine

transformer.fit(trainVectorizerArray)
print
print transformer.transform(trainVectorizerArray).toarray()

transformer.fit(testVectorizerArray)
print 
tfidf = transformer.transform(testVectorizerArray)
print tfidf.todense()

Here is the output:

Fit Vectorizer to train set [[1 0 1 0]
 [0 1 0 1]]
Transform Vectorizer to test set [[0 1 1 1]]
[1 0 1 0]
[0 1 1 1]
0.408
[0 1 0 1]
[0 1 1 1]
0.816

[[ 0.70710678  0.          0.70710678  0.        ]
 [ 0.          0.70710678  0.          0.70710678]]

[[ 0.          0.57735027  0.57735027  0.57735027]]

To forget directory recursively add /*/* to the path:

git update-index --assume-unchanged wordpress/wp-content/uploads/*/*

Using git rm --cached is not good for collaboration. More details here: How to stop tracking and ignore changes to a file in Git?

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

After upgrading to Mountain Lion using the NDK, I had the following error:

Cannot find 'make' program. Please install Cygwin make package or define the GNUMAKE variable to point to it

Error was fixed by downloading and using the latest NDK

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.
