Easy!

Just split the incoming address list on the ";" character, and add them to the mail message:

foreach (var address in addresses.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
    mailMessage.To.Add(address);    
}

In this example, addresses contains "[email protected];[email protected]".

DECLARE @CarList nvarchar(max);
SET @CarList = N'';
SELECT @CarList+=CarName+N','
FROM dbo.CARS;
SELECT LEFT(@CarList,LEN(@CarList)-1);

Thanks are due to whoever on SO showed me the use of accumulating data during a query.

I agree with Jeremy Young's comment on Phils answer:

I have found that this can be a problem associated with migrating from php 5 to php 7. php 5 was more tolerant of amibiguity in whether a variable was an array or not than php 7 is. In most cases the solution is to declare the array explicitly, as explained in this answer.

I was just trouble shooting a Wordpress plugin after the migration of php5 to php7. Since the plugin code was relying on user input, and it was intrinsically used in the code either as string, or as array, I added the following code in to prevent a fatal error:

if(is_array($variable_either_string_or_array)){
    // if it's an array, declaration is allowed:
    $variable_either_string_or_array[]=$additionalInfoData[$i];
}else{
    // if it's not an array, declaration it as follows:
    $variable_either_string_or_array=$additionalInfoData[$i];
}

This was the only modification I needed to add to make the plugin php7-proof. Obviously not "best practices", I'd rather read and understand the full code.. but a quick fix was needed.

I had the same issue until i close teamviewer running on my pc. Then it worked fine!

If you want to check if your -vm eclipse.ini option worked correctly you can use this to see under what JVM the IDE itself runs: menu Help > About Eclipse > Installation Details > Configuration tab. Locate the line that says: java.runtime.version=....

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

You have two options here, 1. Use for instead for foreach for iteration.But in your case the collection is IEnumerable and the upper limit of the collection is unknown so foreach will be the best option. so i prefer to use another integer variable to hold the iteration count: here is the code for that:

int i = 0; // for index
foreach (var row in list)
{
    bool IsChecked;// assign value to this variable
    if (IsChecked)
    {    
       // use i value here                
    }
    i++; // will increment i in each iteration
}

Try using FileUtils.write from Apache Commons.

You should be able to do something like:

File f = new File("output.txt"); 
FileUtils.writeStringToFile(f, document.outerHtml(), "UTF-8");

This will create the file if it does not exist.

Your first problem was you weren't using your compare symbols correctly.

< less than
> greater than
<= less than or equal to
>= greater than or equal to

To answer your other questions; get the condition to work on every cell in the column and what about blanks?

What about blanks?

Add an extra IF condition to check if the cell is blank or not, if it isn't blank perform the check. =IF(B2="","",B2<=TODAY())

Condition on every cell in column

@JonnyBuchanan's answer works perfectly, but for only array state variable. In case the state variable is just a single dictionary, follow this:

inputChange = input => e => {
    this.setState({
        item: update(this.state.item, {[input]: {$set: e.target.value}})
    })
}

You can replace [input] by the field name of your dictionary and e.target.value by its value. This code performs the update job on input change event of my form.

There is also a flag CV_VERSION which will print out the full version of opencv

Use the "$" on a reg expression to match the end of the string

$string = 'The quick brown fox jumps over the lazy fox';
echo preg_replace('/fox$/', 'dog', $string);

//output
'The quick brown fox jumps over the lazy dog'

MSDN seems to indicate that the Cxxx casts for specific types can improve performance in VB .NET because they are converted to inline code. For some reason, it also suggests DirectCast as opposed to CType in certain cases (the documentations states it's when there's an inheritance relationship; I believe this means the sanity of the cast is checked at compile time and optimizations can be applied whereas CType always uses the VB runtime.)

When I'm writing VB .NET code, what I use depends on what I'm doing. If it's prototype code I'm going to throw away, I use whatever I happen to type. If it's code I'm serious about, I try to use a Cxxx cast. If one doesn't exist, I use DirectCast if I have a reasonable belief that there's an inheritance relationship. If it's a situation where I have no idea if the cast should succeed (user input -> integers, for example), then I use TryCast so as to do something more friendly than toss an exception at the user.

One thing I can't shake is I tend to use ToString instead of CStr but supposedly Cstr is faster.

The typical pattern would be as follows, but you need to actually define how the ordering should be applied (since a table is, by definition, an unordered bag of rows):

SELECT t.A, t.B, t.C, number = ROW_NUMBER() OVER (ORDER BY t.A)
  FROM dbo.tableZ AS t
  ORDER BY t.A;

Not sure what the variables in your question are supposed to represent (they don't match).

You can try this:-

IF NULLIF(ISNULL(@PreviousStartDate,''),'') IS NULL
SET @PreviousStartdate = '01/01/2010'

var x = condition || null;

The problem is that Hive doesn't handle quoted texts. You either need to pre-process the data by changing the delimiter between the fields (e.g: with a Hadoop-streaming job) or you can also give a try to use a custom CSV SerDe which uses OpenCSV to parse the files.

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

If flexibility is one of your prerequisites, XSLT might be a good choice, which is completely supported by .NET framework and you would be able to even let the user edit those files. This article (http://www.aspfree.com/c/a/XML/XSL-Transformations-using-ASP-NET/) might be useful for a start (msdn has more info about it). As said by ScarletGarden NVelocity is another good choice but I do prefer XSLT for its " built-in" .NET framework support and platform agnostic.

maybe problem with margin?

padding: 0px;
margin: 0px

I show you here the easiest way using Vs2017 and Vs2019 Open your xsd with Visual Studio and generate a sample xml file as in the url suggested.

1. Once you opened your xsd in design view as below, click on xml schema explorer

2. Within “XML Schema Explorer” scroll all the way down to find the root/data node. Right click on root/data node and it will show “Generate Sample XML”. If it does not show, it means you are not on the data element node but you are on any of the data definition node.

3. Copy your generated Xml into the clipboard
4. Create a new empty class in your solution and delete the class definition. Only Namespace should remain
5. While your mouse pointer focused inside your class, choose EDIT-> Paste Special-> Paste Xml as Classes

If you ignore the characteristics of both languages, how do you define "SPEED"? Which features should be in your benchmark and which do you want to omit?

For example:

• Does it count when Java executes an empty loop faster than Python?
• Or is Python faster when it notices that the loop body is empty, the loop header has no side effects and it optimizes the whole loop away?
• Or is that "a language characteristic"?
• Do you want to know how many bytecodes each language can execute per second?
• Which ones? Only the fast ones or all of them?
• How do you count the Java VM JIT compiler which turns bytecode into CPU-specific assembler code at runtime?
• Do you include code compilation times (which are extra in Java but always included in Python)?

Conclusion: Your question has no answer because it isn't defined what you want. Even if you made it more clear, the question will probably become academic since you will measure something that doesn't count in real life. For all of my projects, both Java and Python have always been fast enough. Of course, I would prefer one language over the other for a specific problem in a certain context.

For those like me who are brand new to this, here is code with const and an actual way to compare the byte[]'s. I got all of this code from stackoverflow but defined consts so values could be changed and also

// 24 = 192 bits
    private const int SaltByteSize = 24;
    private const int HashByteSize = 24;
    private const int HasingIterationsCount = 10101;


    public static string HashPassword(string password)
    {
        // http://stackoverflow.com/questions/19957176/asp-net-identity-password-hashing

        byte[] salt;
        byte[] buffer2;
        if (password == null)
        {
            throw new ArgumentNullException("password");
        }
        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, SaltByteSize, HasingIterationsCount))
        {
            salt = bytes.Salt;
            buffer2 = bytes.GetBytes(HashByteSize);
        }
        byte[] dst = new byte[(SaltByteSize + HashByteSize) + 1];
        Buffer.BlockCopy(salt, 0, dst, 1, SaltByteSize);
        Buffer.BlockCopy(buffer2, 0, dst, SaltByteSize + 1, HashByteSize);
        return Convert.ToBase64String(dst);
    }

    public static bool VerifyHashedPassword(string hashedPassword, string password)
    {
        byte[] _passwordHashBytes;

        int _arrayLen = (SaltByteSize + HashByteSize) + 1;

        if (hashedPassword == null)
        {
            return false;
        }

        if (password == null)
        {
            throw new ArgumentNullException("password");
        }

        byte[] src = Convert.FromBase64String(hashedPassword);

        if ((src.Length != _arrayLen) || (src[0] != 0))
        {
            return false;
        }

        byte[] _currentSaltBytes = new byte[SaltByteSize];
        Buffer.BlockCopy(src, 1, _currentSaltBytes, 0, SaltByteSize);

        byte[] _currentHashBytes = new byte[HashByteSize];
        Buffer.BlockCopy(src, SaltByteSize + 1, _currentHashBytes, 0, HashByteSize);

        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, _currentSaltBytes, HasingIterationsCount))
        {
            _passwordHashBytes = bytes.GetBytes(SaltByteSize);
        }

        return AreHashesEqual(_currentHashBytes, _passwordHashBytes);

    }

    private static bool AreHashesEqual(byte[] firstHash, byte[] secondHash)
    {
        int _minHashLength = firstHash.Length <= secondHash.Length ? firstHash.Length : secondHash.Length;
        var xor = firstHash.Length ^ secondHash.Length;
        for (int i = 0; i < _minHashLength; i++)
            xor |= firstHash[i] ^ secondHash[i];
        return 0 == xor;
    }

In in your custom ApplicationUserManager, you set the PasswordHasher property the name of the class which contains the above code.

echo "<a href='index.php'>Index Page</a>";

if you wanna use html tag like anchor tag you have to put in echo

echo "|$COMMAND|"|tr '\n' ' '

will replace the newline (in POSIX/Unix it's not a carriage return) with a space.

To be honest I would think about switching away from bash to something more sane though. Or avoiding generating this malformed data in the first place.

Hmmm, this seems like it could be a horrible security hole as well, depending on where the data is coming from.

Put this line in your Activity in the Manifest:

<activity android:name=".MainActivity"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        ...
    </activity>

and make sure you didn't put Toolbar in your layout

 <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            />

void foo() {
  /* do some stuff */
  if (!condition) {
    return;
  }
}

You can just use the return keyword just like you would in any other function.

List<String> list = new ArrayList<String>(Arrays.asList("", "Hi", null, "How"));
System.out.println(list);
list.removeAll(Arrays.asList("", null));
System.out.println(list);

Output:

[, Hi, null, How]
[Hi, How]

kubectl get pods -o wide

Give you a list of pods with name, status, ip, node...

The above answers are good and you can do it in a simple way also.

You can use the recursive method calls.

func vibrateTheDeviceContinuously() throws {
        
        // Added concurrent queue for next & Vibrate device
        DispatchQueue.global(qos: .utility).async {
            
            //Vibrate the device
            AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

            self.incrementalCount += 1
            usleep(800000) // if you don't want, remove this line.

            do {
                if let isKeepBuzzing = self.iShouldKeepBuzzing , isKeepBuzzing == true {
                    try self.vibrateTheDeviceContinuously()
                }
                 else {
                    return 
                 }
                
            } catch  {
                //Exception handle
               print("exception")
            }
            
        }
    }

To stop the device vibration use the following line.

self.iShouldKeepBuzzing = false

SELECT * FROM `calendar` WHERE startTime like '2010-04-29%'

You can also use comparison operators on MySQL dates if you want to find something after or before. This is because they are written in such a way (largest value to smallest with leading zeros) that a simple string sort will sort them correctly.

Mac already has Python and a package manager called easy_install, so open Terminal and type

sudo easy_install selenium

To convert UTC time to Local you have to use moment.local().

For more info see docs

Example:

var date = moment.utc().format('YYYY-MM-DD HH:mm:ss');

console.log(date); // 2015-09-13 03:39:27

var stillUtc = moment.utc(date).toDate();
var local = moment(stillUtc).local().format('YYYY-MM-DD HH:mm:ss');

console.log(local); // 2015-09-13 09:39:27

Demo:

var date = moment.utc().format();_x000D_
console.log(date, "- now in UTC"); _x000D_
_x000D_
var local = moment.utc(date).local().format();_x000D_
console.log(local, "- UTC now to local"); 

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>

One very interesting point about Python's attribute lookup is that it can be used to create "virtual variables":

class A(object):

  label="Amazing"

  def __init__(self,d): 
      self.data=d

  def say(self): 
      print("%s %s!"%(self.label,self.data))

class B(A):
  label="Bold"  # overrides A.label

A(5).say()      # Amazing 5!
B(3).say()      # Bold 3!

Normally there aren't any assignments to these after they are created. Note that the lookup uses self because, although label is static in the sense of not being associated with a particular instance, the value still depends on the (class of the) instance.

Working Code:

<TextView
    android:id="@+id/scroller"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:singleLine="true"
    android:text="Some veryyyyy long text with all the characters that cannot fit in screen, it so sad :( that I will not scroll"
    android:textAppearance="?android:attr/textAppearanceLarge" />

Coming from SQL Server as well, and this really bugged me. For those using Toad Data Point or Toad for Oracle, it's extremely simple. Just putting a colon in front of your variable name will prompt Toad to open a dialog where you enter the value on execute.

SELECT * FROM some_table WHERE some_column = :var_name;

Any improvements that could be made would be micro-optimizations, the overall algorithm is correct.

You can find the second largest value with at most 2·(N-1) comparisons and two variables that hold the largest and second largest value:

largest := numbers[0];
secondLargest := null
for i=1 to numbers.length-1 do
    number := numbers[i];
    if number > largest then
        secondLargest := largest;
        largest := number;
    else
        if number > secondLargest then
            secondLargest := number;
        end;
    end;
end;

From the Document "Mastering the VI editor":

Sometimes Xcode when overrides methods adds class func instead of just func. Then in static method you can't see instance properties. It is very easy to overlook it. That was my case.

I review your url in use:

https://www.facebook.com/sharer/sharer.php?s=100&p[title]=EXAMPLE&p[summary]=EXAMPLE&p[url]=EXAMPLE&p[images][0]=EXAMPLE

and see this differences:

1. The sharer URL not is same.
2. The strings are in different order. ( Do not know if this affects ).

I use this URL string:

http://www.facebook.com/sharer.php?s=100&p[url]=http://www.example.com/&p[images][0]=/images/image.jpg&p[title]=Title&p[summary]=Summary

In the "title" and "summary" section, I use the php function urlencode(); like this:

<?php echo urlencode($detail->title); ?>

And working fine for me.

Since mongo-connector now appears dead, my company decided to build a tool for using Mongo change streams to output to Elasticsearch.

Our initial results look promising. You can check it out at https://github.com/electionsexperts/mongo-stream. We're still early in development, and would welcome suggestions or contributions.

The best solution would be to read in the file, then decide which kind of image it is and send out the appropriate header

$filename = basename($file);
$file_extension = strtolower(substr(strrchr($filename,"."),1));

switch( $file_extension ) {
    case "gif": $ctype="image/gif"; break;
    case "png": $ctype="image/png"; break;
    case "jpeg":
    case "jpg": $ctype="image/jpeg"; break;
    case "svg": $ctype="image/svg+xml"; break;
    default:
}

header('Content-type: ' . $ctype);

(Note: the correct content-type for JPG files is image/jpeg)

How about:

DELETE guide_category  
  WHERE id_guide_category IN ( 

        SELECT id_guide_category 
          FROM guide_category AS gc
     LEFT JOIN guide AS g 
            ON g.id_guide = gc.id_guide
         WHERE g.title IS NULL

  )

Everyone else's method doesn't account for whitespaces. Obviously nobody really considers a whitespace a special character.

Use this method to detect special characters not including whitespaces:

import re

def detect_special_characer(pass_string): 
  regex= re.compile('[@_!#$%^&*()<>?/\|}{~:]') 
  if(regex.search(pass_string) == None): 
    res = False
  else: 
    res = True
  return(res)

const is like let, it is a LexicalDeclaration (VariableStatement, Declaration) used to define an identifier in your block.

You are trying to mix this with the default keyword, which expects a HoistableDeclaration, ClassDeclaration or AssignmentExpression to follow it.

Therefore it is a SyntaxError.

If you want to const something you need to provide the identifier and not use default.

export by itself accepts a VariableStatement or Declaration to its right.

AFAIK the export in itself should not add anything to your current scope.

The following is fineexport default Tab;

Tab becomes an AssignmentExpression as it's given the name default ^?

export default Tab = connect( mapState, mapDispatch )( Tabs ); is fine

Here Tab = connect( mapState, mapDispatch )( Tabs ); is an AssignmentExpression.

You can use the next extensions which are based on a predicate condition:

    /// <summary>
    /// Find an index of a first element that satisfies <paramref name="match"/>
    /// </summary>
    /// <typeparam name="T">Type of elements in the source collection</typeparam>
    /// <param name="this">This</param>
    /// <param name="match">Match predicate</param>
    /// <returns>Zero based index of an element. -1 if there is not such matches</returns>
    public static int IndexOf<T>(this IList<T> @this, Predicate<T> match)
    {
        @this.ThrowIfArgumentIsNull();
        match.ThrowIfArgumentIsNull();

        for (int i = 0; i < @this.Count; ++i)
            if (match(@this[i]))
                return i;

        return -1;
    }

    /// <summary>
    /// Replace the first occurance of an oldValue which satisfies the <paramref name="removeByCondition"/> by a newValue
    /// </summary>
    /// <typeparam name="T">Type of elements of a target list</typeparam>
    /// <param name="this">Source collection</param>
    /// <param name="removeByCondition">A condition which decides is a value should be replaced or not</param>
    /// <param name="newValue">A new value instead of replaced</param>
    /// <returns>This</returns>
    public static IList<T> Replace<T>(this IList<T> @this, Predicate<T> replaceByCondition, T newValue)
    {
        @this.ThrowIfArgumentIsNull();
        removeByCondition.ThrowIfArgumentIsNull();

        int index = @this.IndexOf(replaceByCondition);
        if (index != -1)
            @this[index] = newValue;

        return @this;
    }

    /// <summary>
    /// Replace all occurance of values which satisfy the <paramref name="removeByCondition"/> by a newValue
    /// </summary>
    /// <typeparam name="T">Type of elements of a target list</typeparam>
    /// <param name="this">Source collection</param>
    /// <param name="removeByCondition">A condition which decides is a value should be replaced or not</param>
    /// <param name="newValue">A new value instead of replaced</param>
    /// <returns>This</returns>
    public static IList<T> ReplaceAll<T>(this IList<T> @this, Predicate<T> replaceByCondition, T newValue)
    {
        @this.ThrowIfArgumentIsNull();
        removeByCondition.ThrowIfArgumentIsNull();

        for (int i = 0; i < @this.Count; ++i)
            if (replaceByCondition(@this[i]))
                @this[i] = newValue;

        return @this;
    }

Notes: - Instead of ThrowIfArgumentIsNull extension, you can use a general approach like:

if (argName == null) throw new ArgumentNullException(nameof(argName));

So your case with these extensions can be solved as:

string targetString = valueFieldValue.ToString();
listofelements.Replace(x => x.Equals(targetString), value.ToString());

UPDATE:

Time has changed, you can now remove (expire) TestFlight Builds as in this answer but you still cannot delete the build.

OLD:

I asked apple and here is their answer:

I understand you would like to remove a build from iTunes Connect as shown in your screenshot.

Please be advised this is expected behavior as you can remove a build from being the current build but you cannot delete it from iTunes Connect. For more information, please refer to the iTunes Connect Developer Guide: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/

So i just can't.

Your statement does nothing more than ask the interpreter to assign the value returned from then() to the vm.feed variable. then() returns you a Promise (as you can see here: https://github.com/angular/angular.js/blob/master/src/ng/q.js#L283). You could picture this by seeing that the Promise (a simple object) is being pulled out of the function and getting assigned to vm.feed. This happens as soon as the interpreter executes that line.

Since your successful callback does not run when you call then() but only when your promise gets resolved (at a later time, asynchronously) it would be impossible for then() to return its value for the caller. This is the default way Javascript works. This was the exact reason Promises were introduced, so you could ask the interpreter to push the value to you, in the form of a callback.

Though on a future version that is being worked on for JavaScript (ES2016) a couple keywords will be introduced to work pretty much as you are expecting right now. The good news is you can start writing code like this today through transpilation from ES2016 to the current widely supported version (ES5).

A nice introduction to the topic is available at: https://www.youtube.com/watch?v=lil4YCCXRYc

To use it right now you can transpile your code through Babel: https://babeljs.io/docs/usage/experimental/ (by running with --stage 1).

You can also see some examples here: https://github.com/lukehoban/ecmascript-asyncawait.

MySQL has a concept of user-defined variables.

They are loosely typed variables that may be initialized somewhere in a session and keep their value until the session ends.

They are prepended with an @ sign, like this: @var

You can initialize this variable with a SET statement or inside a query:

SET @var = 1

SELECT @var2 := 2

When you develop a stored procedure in MySQL, you can pass the input parameters and declare the local variables:

DELIMITER //

CREATE PROCEDURE prc_test (var INT)
BEGIN
    DECLARE  var2 INT;
    SET var2 = 1;
    SELECT  var2;
END;
//

DELIMITER ;

These variables are not prepended with any prefixes.

The difference between a procedure variable and a session-specific user-defined variable is that a procedure variable is reinitialized to NULL each time the procedure is called, while the session-specific variable is not:

CREATE PROCEDURE prc_test ()
BEGIN
    DECLARE var2 INT DEFAULT 1;
    SET var2 = var2 + 1;
    SET @var2 = @var2 + 1;
    SELECT  var2, @var2;
END;

SET @var2 = 1;

CALL prc_test();

var2  @var2
---   ---
2     2


CALL prc_test();

var2  @var2
---   ---
2     3


CALL prc_test();

var2  @var2
---   ---
2     4

As you can see, var2 (procedure variable) is reinitialized each time the procedure is called, while @var2 (session-specific variable) is not.

(In addition to user-defined variables, MySQL also has some predefined "system variables", which may be "global variables" such as @@global.port or "session variables" such as @@session.sql_mode; these "session variables" are unrelated to session-specific user-defined variables.)

I kept running into this problem when trying to capture JSON data in the log with the Python logging library, for debugging and troubleshooting purposes. Getting the u character is a real nuisance when you want to copy the text and paste it into your code somewhere.

As everyone will tell you, this is because it is a Unicode representation, and it could come from the fact that you’ve used json.loads() to load in the data from a string in the first place.

If you want the JSON representation in the log, without the u prefix, the trick is to use json.dumps() before logging it out. For example:

import json
import logging

# Prepare the data
json_data = json.loads('{"key": "value"}')

# Log normally and get the Unicode indicator
logging.warning('data: {}'.format(json_data))
>>> WARNING:root:data: {u'key': u'value'}

# Dump to a string before logging and get clean output!
logging.warning('data: {}'.format(json.dumps(json_data)))
>>> WARNING:root:data: {'key': 'value'}

What about

str1.localeCompare(str2)

I manage to solve it by hitting a update button

It is Possible to add Multiple Get and Post methods in the same Web API Controller. Here default Route is Causing the Issue. Web API checks for Matching Route from Top to Bottom and Hence Your Default Route Matches for all Requests. As per default route only one Get and Post Method is possible in one controller. Either place the following code on top or Comment Out/Delete Default Route

    config.Routes.MapHttpRoute("API Default", 
                               "api/{controller}/{action}/{id}",
                               new { id = RouteParameter.Optional });

<?php
$host = "localhost";
$uname = "root";
$pass = "";
$database = "demo1"; //Change Your Database Name
$conn = new mysqli($host, $uname, $pass, $database);
$filename = 'users.sql'; //How to Create SQL File Step : url:http://localhost/phpmyadmin->detabase select->table select->Export(In Upper Toolbar)->Go:DOWNLOAD .SQL FILE
$op_data = '';
$lines = file($filename);
foreach ($lines as $line)
{
    if (substr($line, 0, 2) == '--' || $line == '')//This IF Remove Comment Inside SQL FILE
    {
        continue;
    }
    $op_data .= $line;
    if (substr(trim($line), -1, 1) == ';')//Breack Line Upto ';' NEW QUERY
    {
        $conn->query($op_data);
        $op_data = '';
    }
}
echo "Table Created Inside " . $database . " Database.......";
?>

You can also add linker flags to a specific target using the LINK_FLAGS property:

set_property(TARGET ${target} APPEND_STRING PROPERTY LINK_FLAGS " ${flag}")

If you want to propagate this change to other targets, you can create a dummy target to link to.

The shortcut to comment out or uncomment the selected text or current line:

• Windows: Ctrl+/
• Mac: Command ?+/
• Linux: Ctrl+Shift+/

Alternatively, use the menu: Edit > Comment

For the block comment you may want to use:

• Windows: Ctrl+Shift+/
• Mac: Command ?+Option/Alt+/

I faced the exact same issue and notice that after installing node.js there was a new path entry in the user variable section for PATH with value --> c:\User\\AppData\Roaming\npm. Also the Path entry in the system variable is appended with --> C:\Program Files\nodejs. Now since user variable has preference over system you have two options to fix this. Either delete the path from user variable or correct the right path (C:\Program Files\nodejs). Restart CMD and it should work.

You can use a lookahead:

/(?=\S)[^\\]/

function mySrvc() {
  var callback = function() {

  }
  return {
    onSaveClick: function(fn) {
      callback = fn;
    },
    fireSaveClick: function(data) {
      callback(data);
    }
  }
}

function controllerA($scope, mySrvc) {
  mySrvc.onSaveClick(function(data) {
    console.log(data)
  })
}

function controllerB($scope, mySrvc) {
  mySrvc.fireSaveClick(data);
}

You can use basic css to achieve smooth scroll

html {
  scroll-behavior: smooth;
}

Dynamically you can set the fontfamily similar to android:fontFamily in xml by using this,

For Custom font:

 TextView tv = ((TextView) v.findViewById(R.id.select_item_title));
 Typeface face=Typeface.createFromAsset(getAssets(),"fonts/mycustomfont.ttf"); 
 tv.setTypeface(face);

For Default font:

 tv.setTypeface(Typeface.create("sans-serif-medium",Typeface.NORMAL));

These are the list of default font family used, use any of this by replacing the double quotation string "sans-serif-medium"

FONT FAMILY                    TTF FILE                    

1  casual                      ComingSoon.ttf

If you are using EF6 (Entity Framework 6+), this has changed for database calls to SQL.
See: http://msdn.microsoft.com/en-us/data/dn456843.aspx

use context.Database.BeginTransaction.

From MSDN:

using (var context = new BloggingContext()) 
{ 
    using (var dbContextTransaction = context.Database.BeginTransaction()) 
    { 
        try 
        { 
            context.Database.ExecuteSqlCommand( 
                @"UPDATE Blogs SET Rating = 5" + 
                    " WHERE Name LIKE '%Entity Framework%'" 
                ); 

            var query = context.Posts.Where(p => p.Blog.Rating >= 5); 
            foreach (var post in query) 
            { 
                post.Title += "[Cool Blog]"; 
            } 

            context.SaveChanges(); 

            dbContextTransaction.Commit(); 
        } 
        catch (Exception) 
        { 
            dbContextTransaction.Rollback(); //Required according to MSDN article 
            throw; //Not in MSDN article, but recommended so the exception still bubbles up
        } 
    } 
} 

You could use numpy.arange.

EDIT: The docs prefer numpy.linspace. _{Thanks @Droogans for noticing =)}

This could be because of the reason that the credentials are saved and you need to update those credentials and you can do that by following the below steps

control panel-> credential manager ->under generic credential you will be able to see the credentials related to git

Try to update them if that does not work delete them and add new ones

for other platforms or different versions of the operating system you need to find out where the credentails are saved related to git and update them.

In my case:

First I open config file

sudo vi /etc/mongodb.conf

Comment IP and Port like this

#bind_ip = 127.0.0.1
#port = 27017

Then restart mongodb

sudo service mongodb restart
sudo service mongod restart

Finally, it's work :D

finn@Finn ~ $ mongo
MongoDB shell version: 2.4.9
connecting to: test
> exit

Is mcrypt enabled? You can use phpinfo() to see if it is.

It should be

if (*message == '\0')

In C, simple quotes delimit a single character whereas double quotes are for strings.

There are several ways to do it This is the better way

res.download('/report-12345.pdf')

or in your case this might be

app.get('/download', function(req, res){
  const file = `${__dirname}/upload-folder/dramaticpenguin.MOV`;
  res.download(file); // Set disposition and send it.
});

Know More

You just need:

$("selector").get(0).scrollTo(0, 0)

The difference is that a nested class declaration that is also static can be instantiated outside of the enclosing class.

When you have a nested class declaration that is not static, also known as an inner class, Java won't let you instantiate it except via the enclosing class. The object created out of the inner class is linked to the object created from the outer class, so the inner class can reference the fields of the outer.

But if it's static, then the link does not exist, the outer fields cannot be accessed (except via an ordinary reference like any other object) and you can therefore instantiate the nested class by itself.

Instead of parsing day, month and year you can specify date formats directly using datepicker's formatDate function. In my example I am using "yy-mm-dd", but you can use any format of your choice.

$("#datepicker").datepicker({
    dateFormat: 'yy-mm-dd',
    inline: true,
    minDate: new Date(2010, 1 - 1, 1),
    maxDate: new Date(2010, 12 - 1, 31),
    altField: '#datepicker_value',
    onSelect: function(){
        var fullDate = $.datepicker.formatDate("yy-mm-dd", $(this).datepicker('getDate'));
        var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
        $('#page_output').html(str_output);
    }
});

Other answers mention site.USER_SITE as where Python packages get placed. If you're looking for binaries, these go in {site.USER_BASE}/bin.

If you want to add this directory to your shell's search path, use:

export PATH="${PATH}:$(python3 -c 'import site; print(site.USER_BASE)')/bin"

      <div class="overflow-auto p-3 mb-3 mb-md-0 mr-md-3 bg-light" style="max-width: 260px; max-height: 100px;">
        <strong>Column 0 </strong><br>
        <strong>Column 1</strong><br>
        <strong>Column 2</strong><br>
        <strong>Column 3</strong><br>
        <strong>Column 4</strong><br>
        <strong>Column 5</strong><br>
        <strong>Column 6</strong><br>
        <strong>Column 7</strong><br>
        <strong>Column 8</strong><br>
        <strong>Column 9</strong><br>
        <strong>Column 10</strong><br>
        <strong>Column 11</strong><br>
        <strong>Column 12</strong><br>
        <strong>Column 13</strong><br>
      </div>
    </div>

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

Updated(from @Antoine comment)

    h1 { color:red; } _x000D_
}

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

Why you didn`t use

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

?

Or you can use this

-(void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration

Or this

-(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

Hope it owl be useful )

You can use the zip() and sort() functions to accomplish this:

Python 2.6.5 (r265:79063, Jun 12 2010, 17:07:01)
[GCC 4.3.4 20090804 (release) 1] on cygwin
>>> list1 = [3,2,4,1,1]
>>> list2 = ['three', 'two', 'four', 'one', 'one2']
>>> zipped = zip(list1, list2)
>>> zipped.sort()
>>> slist1 = [i for (i, s) in zipped]
>>> slist1
[1, 1, 2, 3, 4]
>>> slist2 = [s for (i, s) in zipped]
>>> slist2
['one', 'one2', 'two', 'three', 'four']

Hope this helps

To install the GPL version of PyQt5, run (see PyQt5 Project):

pip3 install pyqt5

This will install the Python wheel for your platform and your version of Python (assuming both are supported).

(The wheel will be automatically downloaded from the Python Package Index.)

The PyQt5 wheel includes the necessary parts of the LGPL version of Qt. There is no need to install Qt yourself.

(The required sip is packaged as a separate wheel and will be downloaded and installed automatically.)

Note:

If you get an error message saying something as

No downloads could be found that satisfy the requirement 

then you are probably using an unsupported version of Python.

Add hamcrest-all-X.X.jar to your classpath.

Latest version as of Feb 2015 is 1.3: http://code.google.com/p/hamcrest/downloads/detail?name=hamcrest-all-1.3.jar&can=2&q=

You can specify the color option as a list directly to the plot function.

from matplotlib import pyplot as plt
from itertools import cycle, islice
import pandas, numpy as np  # I find np.random.randint to be better

# Make the data
x = [{i:np.random.randint(1,5)} for i in range(10)]
df = pandas.DataFrame(x)

# Make a list by cycling through the colors you care about
# to match the length of your data.
my_colors = list(islice(cycle(['b', 'r', 'g', 'y', 'k']), None, len(df)))

# Specify this list of colors as the `color` option to `plot`.
df.plot(kind='bar', stacked=True, color=my_colors)

To define your own custom list, you can do a few of the following, or just look up the Matplotlib techniques for defining a color item by its RGB values, etc. You can get as complicated as you want with this.

my_colors = ['g', 'b']*5 # <-- this concatenates the list to itself 5 times.
my_colors = [(0.5,0.4,0.5), (0.75, 0.75, 0.25)]*5 # <-- make two custom RGBs and repeat/alternate them over all the bar elements.
my_colors = [(x/10.0, x/20.0, 0.75) for x in range(len(df))] # <-- Quick gradient example along the Red/Green dimensions.

The last example yields the follow simple gradient of colors for me:

I didn't play with it long enough to figure out how to force the legend to pick up the defined colors, but I'm sure you can do it.

In general, though, a big piece of advice is to just use the functions from Matplotlib directly. Calling them from Pandas is OK, but I find you get better options and performance calling them straight from Matplotlib.

From the official JAR File Specification (link goes to the Java 7 version, but the text hasn't changed since at least v1.3):

The META-INF directory

The following files/directories in the META-INF directory are recognized and interpreted by the Java 2 Platform to configure applications, extensions, class loaders and services:

• MANIFEST.MF

The manifest file that is used to define extension and package related data.

• INDEX.LIST

This file is generated by the new "-i" option of the jar tool, which contains location information for packages defined in an application or extension. It is part of the JarIndex implementation and used by class loaders to speed up their class loading process.

• x.SF

The signature file for the JAR file. 'x' stands for the base file name.

• x.DSA

The signature block file associated with the signature file with the same base file name. This file stores the digital signature of the corresponding signature file.

• services/

This directory stores all the service provider configuration files.

May I suggest using the fish bone operator?

for (auto x = std::end(a); x != std::begin(a); )
{
    std::cout <<*--x<< ' ';
}

(Can you spot it?)

I just ran into this problem myself.

First, modify your code slightly:

var download = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                  +"<"+this.gamesave.tagName+">"
                  +this.xml.firstChild.innerHTML
                  +"</"+this.gamesave.tagName+">";

this.loader.src = "data:application/x-forcedownload;base64,"+
                  btoa(download);

Then use your favorite web inspector, put a breakpoint on the line of code that assigns this.loader.src, then execute this code:

for (var i = 0; i < download.length; i++) {
  if (download[i].charCodeAt(0) > 255) {
    console.warn('found character ' + download[i].charCodeAt(0) + ' "' + download[i] + '" at position ' + i);
  }
}

Depending on your application, replacing the characters that are out of range may or may not work, since you'll be modifying the data. See the note on MDN about unicode characters with the btoa method:

https://developer.mozilla.org/en-US/docs/Web/API/window.btoa

You should use the to_date function (oracle/functions/to_date.php )

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');

do you use Bash? Go to the file .bashrc in your home directory and set the variable, then export it.

DISPLAY=localhost:0.0 ; export DISPLAY

you can use /etc/bashrc if you want to do it for all the users.

You may also want to look in ~/.bash_profile and /etc/profile

EDIT:

function get_xserver ()
{
    case $TERM in
       xterm )
            XSERVER=$(who am i | awk '{print $NF}' | tr -d ')''(' )    
            XSERVER=${XSERVER%%:*}
            ;;
        aterm | rxvt)           
            ;;
    esac  
}

if [ -z ${DISPLAY:=""} ]; then
    get_xserver
    if [[ -z ${XSERVER}  || ${XSERVER} == $(hostname) || \
      ${XSERVER} == "unix" ]]; then 
        DISPLAY=":0.0"          # Display on local host.
    else
        DISPLAY=${XSERVER}:0.0  # Display on remote host.
    fi
fi

export DISPLAY

if you are using boolean variable to bind the radio button. please refer below sample code

<div ng-repeat="book in books"> 
<input type="radio" ng-checked="book.selected"  
ng-click="function($event)">                        
</div>

I finally got to solve the problem: UNINSTALL Gallio

Gallio seems to have quite some many rough edges and it's better to not use MbUnit 3.0 but use the MbUnit 2.0 framework but use the gallio runner, that you are running without installing from the installer (which also installed a visual studio plugin).

Incidentally, I had the issue even after "disabling" he Gallio plugin. Only the uninstall solved the problem.

PS. Edited by nightcoder:
In my case disabling TypeMock Isolator (mocking framework) finally helped! Edit & Continue now works!!!

Here is the answer from TypeMock support:

After looking further into the edit and continue issue, and conversing about it with Microsoft, we reached the conclusion it cannot be resolved for Isolator. Isolator implements a CLR profiler, and according to our research, once a CLR profiler is enabled and attached, edit and continue is automatically disabled. I'm sorry to say this is no longer considered a bug, but rather a limitation of Isolator.

This kind of thing is not easy. Here is a method that calls a static method:

public static Object callStaticMethod(
    // class that contains the static method
    final Class<?> clazz,
    // method name
    final String methodName,
    // optional method parameters
    final Object... parameters) throws Exception{
    for(final Method method : clazz.getMethods()){
        if(method.getName().equals(methodName)){
            final Class<?>[] paramTypes = method.getParameterTypes();
            if(parameters.length != paramTypes.length){
                continue;
            }
            boolean compatible = true;
            for(int i = 0; i < paramTypes.length; i++){
                final Class<?> paramType = paramTypes[i];
                final Object param = parameters[i];
                if(param != null && !paramType.isInstance(param)){
                    compatible = false;
                    break;
                }

            }
            if(compatible){
                return method.invoke(/* static invocation */null,
                    parameters);
            }
        }
    }
    throw new NoSuchMethodException(methodName);
}

Update: Wait, I just saw the gwt tag on the question. You can't use reflection in GWT

There is no any problem to write multiple lines of execution withing a single try catch block like below

try{
install_engine();
install_break();
}
catch(Exception $e){
show_exception($e->getMessage());
}

The moment any execption occure either in install_engine or install_break function the control will be passed to catch function. One more recommendation is to eat your exception properly. Which means instead of writing die('Message') it is always advisable to have exception process properly. You may think of using die() function in error handling but not in exception handling.

When you should use multiple try catch block You can think about multiple try catch block if you want the different code block exception to display different type of exception or you are trying to throw any exception from your catch block like below:

try{
    install_engine();
    install_break();
    }
    catch(Exception $e){
    show_exception($e->getMessage());
    }
try{
install_body();
paint_body();
install_interiour();
}
catch(Exception $e){
throw new exception('Body Makeover faield')
}

If you want to define your ItemReader instance and your Step instance in a single JavaConfig class. You can use the @StepScope and the @Value annotations such as:

@Configuration
public class ContributionCardBatchConfiguration {

   private static final String WILL_BE_INJECTED = null;

   @Bean
   @StepScope
   public FlatFileItemReader<ContributionCard> contributionCardReader(@Value("#{jobParameters['fileName']}")String contributionCardCsvFileName){

     ....
   }

   @Bean
   Step ingestContributionCardStep(ItemReader<ContributionCard> reader){
         return stepBuilderFactory.get("ingestContributionCardStep")
                 .<ContributionCard, ContributionCard>chunk(1)
                 .reader(contributionCardReader(WILL_BE_INJECTED))
                 .writer(contributionCardWriter())
                 .build();
    }
}

The trick is to pass a null value to the itemReader since it will be injected through the @Value("#{jobParameters['fileName']}") annotation.

As of laravel 5.5 if the file is stored on a remote storage

return Storage::response($path_to_file);

or if it's locally stored you can also use

return response()->file($path_to_file);

I would recommend using the Storage facade.

def rescale_by_height(image, target_height, method=cv2.INTER_LANCZOS4):
    """Rescale `image` to `target_height` (preserving aspect ratio)."""
    w = int(round(target_height * image.shape[1] / image.shape[0]))
    return cv2.resize(image, (w, target_height), interpolation=method)

def rescale_by_width(image, target_width, method=cv2.INTER_LANCZOS4):
    """Rescale `image` to `target_width` (preserving aspect ratio)."""
    h = int(round(target_width * image.shape[0] / image.shape[1]))
    return cv2.resize(image, (target_width, h), interpolation=method)

Labeled Break

outerloop:
$(sentences).each(function() 
{
    $(words).each(function(i) 
    {
        break; /* breaks inner loop */
    } 
    $(words).each(function(i)  
    {
        break outerloop; /* breaks outer loop */
    }
}

You can use a variable to count places in the array, so when ever you add a new element, you put it in the right place. For example:

int a = 0;
int arr[5] = { };
arr[a] = 6;
a++;

even better:

lsct () 
{ 
    debugfs -R 'stat <'`ls -i "$1" | (read a b;echo -n $a)`'>' `df "$1" | (read a; read a b; echo "$a")` 2> /dev/null | grep --color=auto crtime | ( read a b c d;
    echo $d )
}

lsct /etc

Checkout the -maxdepth flag of find

find . -maxdepth 1 -type d -exec ls -ld "{}" \;

Here I used 1 as max level depth, -type d means find only directories, which then ls -ld lists contents of, in long format.

You need to use strcmp:

strcmp(namet2, nameIt2)

Put this right before the closing Body tag at the bottom of the page.

<script>
    if (location.hash) {
        location.href = location.hash;
    }

If your main element has some child elements or text, you could make use of it.

Position your main element relative (or absolute/fixed) and use both :before and :after positioned absolute (in my situation it had to be absolute, don't know about your's).

Now if you want one more pseudo-element, attach an absolute :before to one of the main element's children (if you have only text, put it in a span, now you have an element), which is not relative/absolute/fixed.

This element will start acting like his owner is your main element.

HTML

<div class="circle">
    <span>Some text</span>
</div>

CSS

.circle {
    position: relative; /* or absolute/fixed */
}

.circle:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle:after {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

.circle span {
    /* not relative/absolute/fixed */
}

.circle span:before {
    position: absolute;
    content: "";
    /* more styles: width, height, etc */
}

You can directly access a global variable inside a function. If you want to change the value of that global variable, use "global variable_name". See the following example:

var = 1
def global_var_change():
      global var
      var = "value changed"
global_var_change() #call the function for changes
print var

Generally speaking, this is not a good programming practice. By breaking namespace logic, code can become difficult to understand and debug.

This answer took me forever to find as well. I discovered that all you have to do is concatenate the URL ('?' after the file name and extension) with the URL-encoded query string. It doesn't even look like you have to set the POST cURL options. See the fake example below:

//create URL
$exampleURL = 'http://www.example.com/example.php?';

// create curl resource
$ch = curl_init(); 

// build URL-encoded query string
$data = http_build_query(
    array('first' => 'John', 'last' => 'Smith', '&'); // set url
curl_setopt($ch, CURLOPT_URL, $exampleURL . $data); 

// return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string
$output = curl_exec($ch); 

// close curl resource to free up system resources <br/>
curl_close($ch);

You can also use file_get_contents():

// read entire webpage file into a string
$output = file_get_contents($exampleURL . $data);

YES!

But you can't do it in the way you may immediately think, because you cant animate or create a transition around the properties you'd otherwise rely on (e.g. display, or changing dimensions and setting to overflow:hidden) in order to correctly hide the element and prevent it from taking up visible space.

Therefore, create an animation for the elements in question, and simply toggle visibility:hidden; after 5 seconds, whilst also setting height and width to zero to prevent the element from still occupying space in the DOM flow.

FIDDLE

CSS

html, body {
    height:100%;
    width:100%;
    margin:0;
    padding:0;
}
#hideMe {
    -moz-animation: cssAnimation 0s ease-in 5s forwards;
    /* Firefox */
    -webkit-animation: cssAnimation 0s ease-in 5s forwards;
    /* Safari and Chrome */
    -o-animation: cssAnimation 0s ease-in 5s forwards;
    /* Opera */
    animation: cssAnimation 0s ease-in 5s forwards;
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;
}
@keyframes cssAnimation {
    to {
        width:0;
        height:0;
        overflow:hidden;
    }
}
@-webkit-keyframes cssAnimation {
    to {
        width:0;
        height:0;
        visibility:hidden;
    }
}

HTML

<div id='hideMe'>Wait for it...</div>

Consider this code:

Products::whereIn('id', function($query){
    $query->select('paper_type_id')
    ->from(with(new ProductCategory)->getTable())
    ->whereIn('category_id', ['223', '15'])
    ->where('active', 1);
})->get();

For me the error came after changing my password for my AD account.

I had to remove the line from credential manager (which contained the previous password.)

Then it worked again.

Why not use them in the Users directory in the .bash_profile file, so you don't have to push any files with your variables to production?

Add timestamps to your Schema like this then createdAt and updatedAt will automatic generate for you

var UserSchema = new Schema({
    email: String,
    views: { type: Number, default: 0 },
    status: Boolean
}, { timestamps: {} });

Also you can change createdAt -> created_at by

timestamps: { createdAt: 'created_at', updatedAt: 'updated_at' }

This plugin is documented rather good in https://polylang.wordpress.com/documentation.

Switching post language

The developers documentation states the following logic as a means to generate URL's for different translations of the same post

<?php while ( have_posts() ) : the_post(); ?>
<ul class='translations'><?php pll_the_languages(array('post_id' =>; $post->ID)); ?></ul>
<?php the_content(); ?>
<?php endwhile; ?>

If you want more influence on what is rendered, inspet pll_the_languages function and copy it's behaviour to your own output implementation

Switching site language

As you want buttons to switch language, this page: https://polylang.wordpress.com/documentation/frequently-asked-questions/the-language-switcher/ will give you the required info.

An implementation example:

<ul><?php pll_the_languages();?></ul>

Then style with CSS to create buttons, flags or whatever you want. It is also possible to use a widget for this, provided by te plugin

Getting current language

All plugins functions are explained here: https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/

In this case use:

pll_current_language();

AttachToRoot Set to True

Just think we specified a button in an XML layout file with its layout width and layout height set to match_parent.

<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/custom_button">
</Button>

On This Buttons Click Event We Can Set Following Code to Inflate Layout on This Activity.

LayoutInflater inflater = LayoutInflater.from(getContext());
inflater.inflate(R.layout.yourlayoutname, this);

Hope this solution works for you.!

Two more uses not mentioned in other answers:

Logging

Take this example script:

set -x
: Logging message here
example_command

The first line, set -x, makes the shell print out the command before running it. It's quite a useful construct. The downside is that the usual echo Log message type of statement now prints the message twice. The colon method gets round that. Note that you'll still have to escape special characters just like you would for echo.

Cron job titles

I've seen it being used in cron jobs, like this:

45 10 * * * : Backup for database ; /opt/backup.sh

This is a cron job that runs the script /opt/backup.sh every day at 10:45. The advantage of this technique is that it makes for better looking email subjects when the /opt/backup.sh prints some output.

The list() function ^[docs] will convert a string into a list of single-character strings.

>>> list('hello')
['h', 'e', 'l', 'l', 'o']

Even without converting them to lists, strings already behave like lists in several ways. For example, you can access individual characters (as single-character strings) using brackets:

>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'

You can also loop over the characters in the string as you can loop over the elements of a list:

>>> for c in 'hello':
...     print c + c,
... 
hh ee ll ll oo

Based on your comments, we need to go over how the Bundling mechanism works in MVC.

Edit: Based on the comment below by VSDev, you need to ensure WebGrease is installed into your project. NuGet would be the easiest was to install this package.

When you set a bundle configuration (Example not from above to illustrate)

bundles.Add(new ScriptBundle("~/bundles/mainJs")
      .Include("~/Scripts/mainSite.js")
      .Include("~/Scripts/helperStuff.js");

You then, in your views, call something like @Scripts.Render("~/bundles/mainJs"). When your web.config is set into a debug compilation OR you explicitly turn off bundling using the following line in your BundleConfig.cs file

BundleTable.EnableOptimizations = false;

Then, in your view, you will see the following rendered out

<script src="/Scripts/mainSite.js" type="text/javascript"></script>
<script src="/Scripts/helperStuff.js" type="text/javascript"></script>

These are the individual items that made up our bundle, uncompressed and listed individually. The reason these list out individually in debug mode is so that you can debug your scripts and see them as you wrote them (actual variable names, etc).

Now, when we are not in a debug compilation and have not turned off the EnableOptimizations feature, MVC will combine those files in our bundles, compress (minify) them and output only a single script tag.

<script src="/bundles/mainJs?v=someBigLongNumber" type="text/javascript"></script>

Notice that the source is the same as the name of the bundle from the bundle configurations. Also, the number after the ?v= will change anytime you change a file in that bundle. This is to help prevent caching of old js and css files by the client browsers.

Your scripts are still there and being outputted, but they are being compressed and combined into a single file called /bundles/mainJs. This feature is present to

A) compress the files and reduce information being transmitted and,

B) reduce the number of calls to a website to retrieve the necessary content to render the page.

Nothing is missing, it sounds like everything is working as intended. In a production site, the minification makes these files almost impossible to read, thus why the minification does not take affect while debugging.

As to why the jQuery UI is still being a single JS file, ensure someone didn't hard code that into your layout view. As for the JS errors, it could be errors that are present on your development box or perhaps something did not compress correctly (however, in all of my MVC development, I have not seen a JS error because of bad minification).

It should be as simple as...

LOAD DATA INFILE '/tmp/mydata.txt' INTO TABLE PerformanceReport;

By default LOAD DATA INFILE uses tab delimited, one row per line, so should take it in just fine.

Set the PGPASSWORD environment variable inside the script before calling psql

PGPASSWORD=pass1234 psql -U MyUsername myDatabaseName

For reference, see http://www.postgresql.org/docs/current/static/libpq-envars.html

Edit

Since Postgres 9.2 there is also the option to specify a connection string or URI that can contain the username and password.

Using that is a security risk because the password is visible in plain text when looking at the command line of a running process e.g. using ps (Linux), ProcessExplorer (Windows) or similar tools, by other users.

The Problem

In MySQL, certain words like SELECT, INSERT, DELETE etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.

As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):

Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.

...

If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.

...

The identifier quote character is the backtick ("`"):

A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.

• ADD
• AND
• BEFORE
• BY
• CALL
• CASE
• CONDITION
• DELETE
• DESC
• DESCRIBE
• FROM
• GROUP
• IN
• INDEX
• INSERT
• INTERVAL
• IS
• KEY
• LIKE
• LIMIT
• LONG
• MATCH
• NOT
• OPTION
• OR
• ORDER
• PARTITION
• RANK
• REFERENCES
• SELECT
• TABLE
• TO
• UPDATE
• WHERE

The Solution

You have two options.

1. Don't use reserved words as identifiers

The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.

Doing this has a couple of advantages:

• It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.

• The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.

Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.

2. Use backticks

If renaming the table or column isn't possible, wrap the offending identifier in backticks (`) as described in the earlier quote from 10.2 Schema Object Names.

An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):

mysql> CREATE TABLE interval (begin INT, end INT);
ERROR 1064 (42000): You have an error in your SQL syntax.
near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT);
Query OK, 0 rows affected (0.01 sec)

Similarly, the query from the question can be fixed by wrapping the keyword key in backticks, as shown below:

INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)";               ^   ^

Here is a simple implementation of the wikipedia algorithm, using the javascript ternary operator:

isLeapYear = (year % 100 === 0) ? (year % 400 === 0) : (year % 4 === 0);

I came across the same issue earlier, then stumbled upon the answer for this. Hope it will help others for future reference.

long answer short, add a border to your child flex-items. then you can specify margins between flex-items to whatever you like. In the snippet, i use black for illustration purposes, you can use 'transparent' if you like.

#box {_x000D_
  display: flex;_x000D_
  width: 100px;_x000D_
  /* margin: 0 -5px; *remove this*/_x000D_
}_x000D_
.item {_x000D_
  background: gray;_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
  /* margin: 0 5px; *remove this*/_x000D_
  border: 1px solid black; /* add this */_x000D_
}_x000D_
.item.special{ margin: 0 10px; }

<div id='box'>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item'></div>_x000D_
  <div class='item special'></div>_x000D_
</div>

The above responses are the better, but just for completeness, when you are in a component you can access the history object inside the VueRouter with: this.$router.history. That means we can listen to changes with:

this.$router.listen((newLocation) =>{console.log(newLocation);})

I think this is mainly useful when used along with this.$router.currentRoute.path You can check what I am talking about placing a debugger

instruction in your code and begin playing with the Chrome DevTools Console.

Look basic:

var namefunction = 'jspure'; // String

function jspure(msg1 = '', msg2 = '') { 
  console.log(msg1+(msg2!=''?'/'+msg2:''));
} // multiple argument

// Results ur test
window[namefunction]('hello','hello again'); // something...
eval[namefunction] = 'hello'; // use string or something, but its eval just one argument and not exist multiple

Exist other type function is class and look example nils petersohn

You should be able to use reduce.

var sum = array.reduce(function(pv, cv) { return pv + cv; }, 0);

Source

And with arrow functions introduced in ES6, it's even simpler:

sum = array.reduce((pv, cv) => pv + cv, 0);

Put the data into a Pivot Table and do a top n filter on it

Inside of VBS you can access parameters with

Wscript.Arguments(0)
Wscript.Arguments(1)

and so on. The number of parameter:

Wscript.Arguments.Count

Solution for Windows (Windows 10) is:

1. Make sure you have Java 8 installed
2. Download Gradle binary from https://gradle.org/install/
3. Create a new directory C:\Gradle with File Explorer
4. Extract and copy gradle-6.7.1 to C:\Gradle
5. Configure your PATH environment variable to include the path C:\Gradle\gradle-6.7.1\bin
6. Run gradle -v to confirm all is okay. C:>Gradle -v

Gradle 6.7.1

I also wouldn't call two many (is_a? and kind_of? are aliases of the same method), but if you want to see more possibilities, turn your attention to #class method:

A = Class.new
B = Class.new A

a, b = A.new, B.new
b.class < A # true - means that b.class is a subclass of A
a.class < B # false - means that a.class is not a subclass of A
# Another possibility: Use #ancestors
b.class.ancestors.include? A # true - means that b.class has A among its ancestors
a.class.ancestors.include? B # false - means that B is not an ancestor of a.class

Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files).

As Ciro mentioned, CPATH will set the path for both C and C++ (and any other language).

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

I meet the same problem in windows restoring a dump file. My dump file was created with windows powershell and mysqldump like:

mysqldump db > dump.sql

The problem comes from the default encoding of powershell is UTF16. To look deeper into this, we can use "file" utility of GNU, and there exists a windows version here.
The output of my dump file is:

Little-endian UTF-16 Unicode text, with very long lines, with CRLF line terminators.

Then a conversion of coding system is needed, and there are various software can do this. For example in emacs,

M-x set-buffer-file-coding-system

then input required coding system such as utf-8.

And in the future, for a better mysqldump result, use:

mysqldump <dbname> -r <filename>

and then the output is handled by mysqldump itself but not redirection of powershell.

Best way is to have a contextual action bar with listview on multiselect, You can make listview as multiselect using the following code

listview.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);

And now set multichoice listener for Listview ,You can see the complete implementation of multiselect listview at Android multi select listview

It may be late. It is Happen because your git HEAD is not updated. this commend would solve that git reset HEAD.

Right. Better to use a function:

CREATE OR REPLACE FUNCTION yyyymm() RETURNS text
    LANGUAGE 'plpgsql' AS $$
DECLARE
    retval text;
    m integer;
BEGIN
    retval := EXTRACT(year from current_timestamp);
    m := EXTRACT(month from current_timestamp);
    IF m < 10 THEN retval := retval || '0'; END IF;
    RETURN retval || m;
END $$;

SELECT yyyymm();

DROP TABLE foo;
CREATE TABLE foo (
    key             int PRIMARY KEY,
    colname text DEFAULT yyyymm()
    );
INSERT INTO foo (key) VALUES (0);
SELECT * FROM FOO;

This gives me

 key | colname 
-----+---------
   0 | 200905

Make sure you run createlang plpgsql from the Unix command line, if necessary.

 //if you want to get parameter from url use:
 parse_str($_SERVER['QUERY_STRING'], $_GET);
 //then you can use:
 if(isset($_GET["par"])){
      echo $_GET["par"];
 }
 //if you want to get current page url use:
 $current_url = current_url();

On bootstrap-modal.js v2.2.0:

( $('element').data('modal') || {}).isShown

The constructor String(byte[] bytes) takes the bytes from the buffer and encodes them to characters.

It uses the platform default charset to encode bytes to characters. If you know, your file contains text, that is encoded in a different charset, you can use the String(byte[] bytes, String charsetName) to use the correct encoding (from bytes to characters).

I have the same problem; the APIs don't have anything to cancel some specific animation. The

+ (void)setAnimationsEnabled:(BOOL)enabled

disables ALL animations, and thus does not work for me. There's two solutions:

1) make your animated object a subview. Then, when you want to cancel the animations for that view, remove the view or hide it. Very simple, but you need to recreate the subview without animations if you need to keep it in view.

2) repeat the anim only one, and make a delegate selector to restart the anim if needed, like this:

-(void) startAnimation {
NSLog(@"startAnim alpha:%f", self.alpha);
[self setAlpha:1.0];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationRepeatCount:1];
[UIView setAnimationRepeatAutoreverses:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(pulseAnimationDidStop:finished:context:)];
[self setAlpha:0.1];
[UIView commitAnimations];
}

- (void)pulseAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
if(hasFocus) {
    [self startAnimation];
} else {
    self.alpha = 1.0;
}
}

-(void) setHasFocus:(BOOL)_hasFocus {
hasFocus = _hasFocus;
if(hasFocus) {
    [self startAnimation];
}
}

Problem with 2) is that there's always delay stopping the anim as it finishes the current animation cycle.

Hope this helps.

My solution was not to rely on the class name. object.constructor.name works in theory. But if you're using TypeScript in something like Ionic, as soon as you go to production it's going to go up in flames because Ionic's production mode minifies the Javascript code. So the classes get named things like "a" and "e."

What I ended up doing was having a typeName class in all my objects that the constructor assigns the class name to. So:

export class Person {
id: number;
name: string;
typeName: string;

constructor() {
typeName = "Person";
}

Yes that wasn't what was asked, really. But using the constructor.name on something that might potentially get minified down the road is just begging for a headache.

based on javascript runtime prototype implementation you can use simple arithmetic to subtract dates as in bellow

var sep = new Date(2020, 07, 31, 23, 59, 59);
var today = new Date();
var diffD = Math.floor((sep - today) / (1000 * 60 * 60 * 24));
console.log('Day Diff: '+diffD);

the difference return answer as milliseconds, then you have to convert it by division:

• by 1000 to convert to second
• by 1000×60 convert to minute
• by 1000×60×60 convert to hour
• by 1000×60×60×24 convert to day

Just define <body onload="aFunction()"> that will be called after the page has been loaded. Your code in the script is than enclosed by aFunction() { }.

Some important and successfully executed software projects like Google Chrome and Mozilla Firefox are fine examples of both iterative and incremental software development.

I will quote fine ars technica article which describes this approach: http://arstechnica.com/information-technology/2010/07/chrome-team-sets-six-week-cadence-for-new-major-versions/

According to Chrome program manager Anthony Laforge, the increased pace is designed to address three main goals. One is to get new features out to users faster. The second is make the release schedule predictable and therefore easier to plan which features will be included and which features will be targeted for later releases. Third, and most counterintuitive, is to cut the level of stress for Chrome developers. Laforge explains that the shorter, predictable time periods between releases are more like "trains leaving Grand Central Station." New features that are ready don't have to wait for others that are taking longer to complete—they can just hop on the current release "train." This can in turn take the pressure off developers to rush to get other features done, since another release train will be coming in six weeks. And they can rest easy knowing their work isn't holding the train from leaving the station.<<

One thing I've noticed that I don't see in the documentation is using background: url("image.png")

short hand like above if the image is not found it sends a 302 code instead of being ignored like it is if you use

background-image: url("image.png") 

void    QWidget::setWindowTitle ( const QString & )

EDIT: If you are using QtDesigner, on the property tab, there is an editable property called windowTitle which can be found under the QWidget section. The property tab can usually be found on the lower right part of the designer window.

In my mind I have to consider that the foo folder is a stand-alone library. I might want to consider moving it to the Lib\site-packages folder within a python installation. I might want to consider adding a foo.pth file there.

I know it's a library since the ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

So it doesn't matter that ./programs is a sibling folder to ./foo. It's the fact that my_python_program.py is run as a script like this:

python ./programs/my_python_program.py

You can extract the href from the a tag:

window.open(document.getElementById('redirect').href);

Try doing this :

recipients="[email protected],[email protected],[email protected]"

And another approach, using shell here-doc :

/usr/sbin/sendmail "$recipients" <<EOF
subject:$subject
from:$from

Example Message
EOF

Be sure to separate the headers from the body with a blank line as per RFC 822.

The angular way is shown in the angular docs :)

https://docs.angularjs.org/api/ng/directive/ngReadonly

Here is the example they use:

<body>
    Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
    <input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>

Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).

So basically in your case you would want to do something like below or check out this working example.

<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>

Java objects reside in an area called the heap, while metadata such as class objects and method objects reside in the permanent generation or Perm Gen area. The permanent generation is not part of the heap.

The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected. During the garbage collection objects that are no longer used are cleared, thus making space for new objects.

-Xmssize Specifies the initial heap size.

-Xmxsize Specifies the maximum heap size.

-XX:MaxPermSize=size Sets the maximum permanent generation space size. This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

Sizes are expressed in bytes. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, g or G to indicate gigabytes.

I encountered the issue with the error:

gyp ERR! configure error

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

Here is what I was doing and what finally worked.

Disclaimer: I am just getting my hands into Node, Angular after many years in the Java, Linux world among others...

Environment Description: Windows 8.1 64-bit; Cygwin; cygwin bash shell

Command used that led to error: npm install -g karma

Error: gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "python", you can set the PYT HON env variable.

Discovery: 'which python' on bash shell clearly shows '/usr/bin/python'. Now that is annoying!

Solution: This is only applicable to those using the environment similar to what I have, i.e. using cygwin and bash shell. Hope it helps in other environments as well but keep in mind that your kettle of tea may look a little different than mine.

1. Firstly, need to set the $PYTHON shell env variable in .bashrc using the explicit windows path to the python executable and not the unix like root path (/usr/bin) used by cygwin.
2. Secondly, and this one took a lot of trial/error and here's the gotcha! Cygwin installs python under /usr/bin (which is really a mirror of /bin on windows) with the version, i.e. (in my system) /usr/bin/python2.7.exe and then adds a link /usr/bin/python --> python2.7.exe. The problem is that gyp cannot follow this link and keeps giving the annoying error that it cannot find python even though you can find it just fine from the shell command line.
3. With the above background now add the following line to your .bashrc

export PYTHON="C:/cygwin64/bin/python2.7.exe (or whatever is the version on your system)"

4. Now source your .bashrc from your home directory (on cygwin)--> 'source .bashrc'

You should be fine now and gyp will find the python executable.

I hope this helps someone stumbling on the same or similar issue.

This is an odd solution, but it worked for me.

I wanted to uninstall Visual Studio 2015 and do a clean install afterwards, but when I tried to remove it through the Control Panel, it was giving me a generic error.

I fixed it by deleting the Visual Studio 2015 folder in Program Files (x86). After that, the Control Panel uninstall worked fine.

In my case the problem was that I had called $("#divDialog").removeData(); as part of resetting my forms data within the dialog.

This resulted in me wiping out a data structure named uiDialog which meant that the dialog had to reinitialize.

I replaced .removeData() with more specific deletes and everything started working again.

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

An Array of Objects

const aListOfObjects = [{
    prop1: 50,
    prop2: "Nothing",
    prop3: "hello",
    prop4: "What's up",
  },
  {
    prop1: 88,
    prop2: "Whatever",
    prop3: "world",
    prop4: "You get it",
  },
]

Making a subset of an object or objects can be achieved by destructuring the object this way.

const sections = aListOfObjects.map(({prop1, prop2}) => ({prop1, prop2}));

For Linux Users:

The solution: In terminal: sudo /etc/init.d/apache2 stop

Edit: If you still get this kind of error at next computer start then you probably have apache2 process starting at computer startup.

To prevent apache2 starting automatically at startup: cd /etc/init.d/ sudo update-rc.d -f apache2 remove

Reboot your computer and now hopefully you can turn on Apache from the XAMPP Control Panel!

if (array[0]=1) should be if (array[0]==1).

The same with else if (array[0]=2).

Note that the expression of the assignment returns the assigned value, in this case if (array[0]=1) will be always true, that's why the code below the if-statement will be always executed if you don't change the = to ==.

= is the assignment operator, you want to compare, not to assign. So you need ==.

Another thing, if you want only one integer, why are you using array? You might want also to scanf("%d", &array[0]);

I'm not sure whether you have access to the Apache config (httpd.conf) but you should be able to set an AddDefaultCharset Directive. See:

http://httpd.apache.org/docs/2.0/mod/core.html

Look for the mod_mime.c module and make sure the following is set:

AddDefaultCharset utf-8 

or the equivalent Apache 1.x docs (http://httpd.apache.org/docs/1.3/mod/core.html#adddefaultcharset).

However, this only works when "the response content-type is text/plain or text/html".

You should also make sure that your pages have a charset set as well. See this for more info:

http://www.w3.org/TR/REC-html40/charset.html

The title "WPF Label Foreground Color" is very simple (exactly what I was looking for) but the OP's code is so cluttered it's easy to miss how simple it can be to set text foreground color on two different labels:

<StackPanel>
    <Label Foreground="Red">Red text</Label>
    <Label Foreground="Blue">Blue text</Label>
</StackPanel>

In summary, No, there was nothing wrong with your snippet.

I've used this directive with success before:

 .directive('sameAs', function() {
  return {
    require: 'ngModel',
    link: function(scope, elm, attrs, ctrl) {
      ctrl.$parsers.unshift(function(viewValue) {
        if (viewValue === scope[attrs.sameAs]) {
          ctrl.$setValidity('sameAs', true);
          return viewValue;
        } else {
          ctrl.$setValidity('sameAs', false);
          return undefined;
        }
      });
    }
  };
});

Usage

     <input ... name="password" />
    <input type="password" placeholder="Confirm Password" 
name="password2" ng-model="password2" ng-minlength="9" same-as='password' required>

Angular CLI 1.x.x (Works with Angular 4.x.x, 5.x.x)

This supports:

• Angular 2.x and 4.x
• Latest Webpack 2.x
• Angular AoT compiler
• Routing (normal and lazy)
• SCSS
• Custom file bundling (assets)
• Additional development tools (linter, unit & end-to-end test setups)

Initial Setup

ng new project-name --routing

You can add --style=scss for SASS .scss support.

You can add --ng4 for using Angular 4 instead of Angular 2.

After creating the project, the CLI will automatically run npm install for you. If you want to use Yarn instead, or just want to look at the project skeleton without install, check how to do it here.

Bundle Steps

Inside the project folder:

ng build -prod

At the current version you need to to specify --aot manually, because it can be used in development mode (although that's not practical due to slowness).

This also performs AoT compilation for even smaller bundles (no Angular compiler, instead, generated compiler output). The bundles are much smaller with AoT if you use Angular 4 as the generated code is smaller.
You can test your app with AoT in development mode (sourcemaps, no minification) and AoT by running ng build --aot.

Output

The default output dir is ./dist, although it can be changed in ./angular-cli.json.

Deployable Files

The result of build step is the following:

(Note: <content-hash> refers to hash / fingerprint of the contents of the file that's meant to be a cache busting way, this is possible since Webpack writes the script tags by itself)

• ./dist/assets
  Files copied as-is from ./src/assets/**
• ./dist/index.html
  From ./src/index.html, after adding webpack scripts to it
  Source template file is configurable in ./angular-cli.json
• ./dist/inline.js
  Small webpack loader / polyfill
• ./dist/main.<content-hash>.bundle.js
  The main .js file containing all the .js scripts generated / imported
• ./dist/styles.<content-hash>.bundle.js
  When you use Webpack loaders for CSS, which is the CLI way, they are loaded via JS here

In older versions it also created gzipped versions for checking their size, and .map sourcemaps files, but this is no longer happening as people kept asking to remove these.

Other Files

In certain other occasions, you might find other unwanted files/folders:

• ./out-tsc/
  From ./src/tsconfig.json's outDir
• ./out-tsc-e2e/
  From ./e2e/tsconfig.json's outDir
• ./dist/ngfactory/
  From AoT compiler (not configurable without forking the CLI as of beta 16)

It's a new era and with Python 3.6.1 dictionaries now retain their order. These semantics aren't explicit because that would require BDFL approval. But Raymond Hettinger is the next best thing (and funnier) and he makes a pretty strong case that dictionaries will be ordered for a very long time.

So now it's easy to create slices of a dictionary:

test_dict = {
                'first':  1,
                'second': 2,
                'third':  3,
                'fourth': 4
            }

list(test_dict.items())[:2]

Note: Dictonary insertion-order preservation is now official in Python 3.7.

i think this is also because of incorrect compilation..

What is Stroke:

The BasicStroke class defines a basic set of rendering attributes for the outlines of graphics primitives, which are rendered with a Graphics2D object that has its Stroke attribute set to this BasicStroke.

https://docs.oracle.com/javase/7/docs/api/java/awt/BasicStroke.html

Note that the Stroke setting:

Graphics2D g2 = (Graphics2D) g;
g2.setStroke(new BasicStroke(10));

is setting the line width,since BasicStroke(float width):

Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles.

And, it also effects other methods like Graphics2D.drawLine(int x1, int y1, int x2, int y2) and Graphics2D.drawRect(int x, int y, int width, int height):

The methods of the Graphics2D interface that use the outline Shape returned by a Stroke object include draw and any other methods that are implemented in terms of that method, such as drawLine, drawRect, drawRoundRect, drawOval, drawArc, drawPolyline, and drawPolygon.

The agg function will do this for you. Pass the columns and function as a dict with column, output:

df.groupby(['Country', 'Item_Code']).agg({'Y1961': np.sum, 'Y1962': [np.sum, np.mean]})  # Added example for two output columns from a single input column

This will display only the group by columns, and the specified aggregate columns. In this example I included two agg functions applied to 'Y1962'.

To get exactly what you hoped to see, included the other columns in the group by, and apply sums to the Y variables in the frame:

df.groupby(['Code', 'Country', 'Item_Code', 'Item', 'Ele_Code', 'Unit']).agg({'Y1961': np.sum, 'Y1962': np.sum, 'Y1963': np.sum})

Works fine:

var obj = document.createElement('div');
obj.id = "::img";
obj.style.cssText = 'position:absolute;top:300px;left:300px;width:200px;height:200px;-moz-border-radius:100px;border:1px  solid #ddd;-moz-box-shadow: 0px 0px 8px  #fff;display:none;';

document.getElementById("divInsteadOfDocument.Write").appendChild(obj);

You can also see how to set the the CSS in one go (using element.style.cssText).

I suggest you use some more meaningful variable names and don't use the same name for different elements. It looks like you are using obj for different elements (overwriting the value in the function) and this can be confusing.

Question states 'I want to drop all the columns whose name contains the word "Test".'

test_columns = [col for col in df if 'Test' in col]
df.drop(columns=test_columns, inplace=True)

NOTE FOR PHP 7

To update on this answer as it has gained some popularity: This answer no longer applies as of PHP 7. As explained in the "Backward incompatible changes", in PHP 7 foreach works on copy of the array, so any changes on the array itself are not reflected on foreach loop. More details at the link.

Explanation (quote from php.net):

The first form loops over the array given by array_expression. On each iteration, the value of the current element is assigned to $value and the internal array pointer is advanced by one (so on the next iteration, you'll be looking at the next element).

So, in your first example you only have one element in the array, and when the pointer is moved the next element does not exist, so after you add new element foreach ends because it already "decided" that it it as the last element.

In your second example, you start with two elements, and foreach loop is not at the last element so it evaluates the array on the next iteration and thus realises that there is new element in the array.

I believe that this is all consequence of On each iteration part of the explanation in the documentation, which probably means that foreach does all logic before it calls the code in {}.

Test case

If you run this:

<?
    $array = Array(
        'foo' => 1,
        'bar' => 2
    );
    foreach($array as $k=>&$v) {
        $array['baz']=3;
        echo $v." ";
    }
    print_r($array);
?>

You will get this output:

1 2 3 Array
(
    [foo] => 1
    [bar] => 2
    [baz] => 3
)

Which means that it accepted the modification and went through it because it was modified "in time". But if you do this:

<?
    $array = Array(
        'foo' => 1,
        'bar' => 2
    );
    foreach($array as $k=>&$v) {
        if ($k=='bar') {
            $array['baz']=3;
        }
        echo $v." ";
    }
    print_r($array);
?>

You will get:

1 2 Array
(
    [foo] => 1
    [bar] => 2
    [baz] => 3
)

Which means that array was modified, but since we modified it when the foreach already was at the last element of the array, it "decided" not to loop anymore, and even though we added new element, we added it "too late" and it was not looped through.

Detailed explanation can be read at How does PHP 'foreach' actually work? which explains the internals behind this behaviour.

In the above given code

assign the php value to javascript variable.

<html>
<?php
 $num = 1;
 echo $num;
?>
  <input type = "button" name = "lol" value = "Click to increment" onclick = "Inc()">
  <br>
  <script>
   var numeric = <?php echo $num; ?>"; //assigns value of the $num to javascript var             numeric 
  function Inc()
   {
     numeric = eVal(numeric) + 1;
     alert("Increamented value: "+numeric);
   }
  </script>
</html>

One thing in combination of PHP and Javsacript is you can not assign javascript value to PHP value. You can assign PHP value to javascript variable.

• Reset your email to the config globally:

  git config --global user.email [email protected]

• Now reset the author of your commit without edit required:

  git commit --amend --reset-author --no-edit

The angular.forEach() will iterate through your json object.

First iteration,

key = 0, value = { "name" : "Thomas", "password" : "thomasTheKing"}

Second iteration,

key = 1, value = { "name" : "Linda", "password" : "lindatheQueen" }

To get the value of your name, you can use value.name or value["name"]. Same with your password, you use value.password or value["password"].

The code below will give you what you want:

   angular.forEach(json, function (value, key)
         {
                //console.log(key);
                //console.log(value);
                if (value.password == "thomasTheKing") {
                    console.log("username is thomas");
                }
         });

Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:

Error in contrasts<-(*tmp*, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels

So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.

You can do something like

for(var k in result) {
   console.log(k, result[k]);
}

which loops over all the keys in the returned json and prints the values. However, if you have a nested structure, you will need to use

typeof result[k] === "object"

to determine if you have to loop over the nested objects. Most APIs I have used, the developers know the structure of what is being returned, so this is unnecessary. However, I suppose it's possible that this expectation is not good for all cases.

Important Update

Go to project level build.gradle, define global variables

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlinVersion = '1.2.61'

    ext.global_minSdkVersion = 16
    ext.global_targetSdkVersion = 28
    ext.global_buildToolsVersion = '28.0.1'
    ext.global_supportLibVersion = '27.1.1'
}

Go to app level build.gradle, and use global variables

app build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

some library build.gradle

android {
    compileSdkVersion global_targetSdkVersion
    buildToolsVersion global_buildToolsVersion
    defaultConfig {
        minSdkVersion global_minSdkVersion
        targetSdkVersion global_targetSdkVersion
}
...

dependencies {
    implementation "com.android.support:appcompat-v7:$global_supportLibVersion"
    implementation "com.android.support:recyclerview-v7:$global_supportLibVersion"
    // and so on...
}

The solution is to make your versions same as in all modules. So that you don't have conflicts.

Important Tips

I felt when I have updated versions of everything- gradle, sdks, libraries etc. then I face less errors. Because developers are working hard to make it easy development on Android Studio.

Always have latest but stable versions Unstable versions are alpha, beta and rc, ignore them in developing.

I have updated all below in my projects, and I don't face these errors anymore.

• Update Android Studio (Track release)
• Project level build.gradle - classpath 'com.android.tools.build:gradle:3.2.0' (Track android.build.gradle release & this)
• Have updated buildToolVersion (Track buildToolVersion release)
• Have latest compileSdkVersion and targetSdkVersion Track platform release
• Have updated library versions, because after above updates, its necessary. (@See How to update)

Happy coding! :)

Add this dependency in project build .gradle.

Follow the example below.

dependencies {

    compile 'com.android.support:appcompat-v7:22.1.0'
}

To answer your question literally, here's how to get the next value of a sequence without incrementing it:

SELECT
 CASE WHEN is_called THEN
   last_value + 1
 ELSE
   last_value
 END
FROM sequence_name

Obviously, it is not a good idea to use this code in practice. There is no guarantee that the next row will really have this ID. However, for debugging purposes it might be interesting to know the value of a sequence without incrementing it, and this is how you can do it.

public static void main(String[] args) {

    LinkedList list = new LinkedList();
    list.insertFront(1);
    list.insertFront(2);
    list.insertFront(3);
    System.out.println(list.toString());
}

String toString() {
            String result = "";
            LinkedListNode current = head;
            while(current.getNext() != null){
                result += current.getData();
                if(current.getNext() != null){
                     result += ", ";
                }
                current = current.getNext();
            }
            return "List: " + result;
}

The accepted answer has to load the whole file into memory, which doesn't work nicely for large files. The following solution writes the file contents with the new data inserted into the right line to a temporary file in the same directory (so on the same file system), only reading small chunks from the source file at a time. It then overwrites the source file with the contents of the temporary file in an efficient way (Python 3.8+).

from pathlib import Path
from shutil import copyfile
from tempfile import NamedTemporaryFile

sourcefile = Path("/path/to/source").resolve()
insert_lineno = 152  # The line to insert the new data into.
insert_data = "..."  # Some string to insert.

with sourcefile.open(mode="r") as source:
    destination = NamedTemporaryFile(mode="w", dir=str(sourcefile.parent))
    lineno = 1

    while lineno < insert_lineno:
        destination.file.write(source.readline())
        lineno += 1

    # Insert the new data.
    destination.file.write(insert_data)

    # Write the rest in chunks.
    while True:
        data = source.read(1024)
        if not data:
            break
        destination.file.write(data)

# Finish writing data.
destination.flush()
# Overwrite the original file's contents with that of the temporary file.
# This uses a memory-optimised copy operation starting from Python 3.8.
copyfile(destination.name, str(sourcefile))
# Delete the temporary file.
destination.close()

EDIT 2020-09-08: I just found an answer on Code Review that does something similar to above with more explanation - it might be useful to some.

You shouldn't use strcpy() to copy a std::string, only use it for C-Style strings.

If you want to copy a to b then just use the = operator.

string a = "text";
string b = "image";
b = a;

both %d and %i can be used to print an integer

%d stands for "decimal", and %i for "integer." You can use %x to print in hexadecimal, and %o to print in octal.

You can use %i as a synonym for %d, if you prefer to indicate "integer" instead of "decimal."

On input, using scanf(), you can use use both %i and %d as well. %i means parse it as an integer in any base (octal, hexadecimal, or decimal, as indicated by a 0 or 0x prefix), while %d means parse it as a decimal integer.

check here for more explanation

why does %d stand for Integer?

Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.

You could consider using PDFObject by Philip Hutchison.

Alternatively, if you're looking for a non-Javascript solution, you could use markup like this:

<object data="myfile.pdf" type="application/pdf" width="100%" height="100%">
  <p>Alternative text - include a link <a href="myfile.pdf">to the PDF!</a></p>
</object>

Try: "\r\n"

Java 7 example:

// append = true
try(PrintWriter output = new PrintWriter(new FileWriter("log.txt",true))) 
{
    output.printf("%s\r\n", "NEWLINE");
} 
catch (Exception e) {}

In case you need to exit Vim in easy mode (while using -y option) you can enter normal Vim mode by hitting Ctrl + L and then any of the normal exiting options will work.

I encountered this error with the Eclipse 4.10 installer. We had failed to complete the install correctly due to platform security settings and attempted to uninstall but had to do it by hand since no uninstaller was introduced during the failed install. We suspected this corrupted the end result - even after re-installing.

The solution was to use the JVM to launch Eclipse and bypass the launcher executable entirely. The following command successfully launches Eclipse 4.10 (some parameters will change based on the version of Eclipse):

%JDK190%\bin\javaw.exe -jar C:\<fully_qualified_path_to_eclipse>\Eclipse410\plugins\org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar -clean -showsplash

After using this command/shortcut to launch Eclipse we had no further errors with Eclipse itself but we weren't able to use the EXE launcher in the future. Even after a year of using this version, the launcher continues to display this same error.

To be clear, you'll have to modify your javaw.exe command to match your system specifications on MS Windows.

In Android Studio: Add support library to the gradle file and sync. Edit build.gradle(Module:app) to have dependencies as follows:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:23.1.1'
    implementation 'com.android.support:design:23.1.1'
    implementation 'com.android.support:support-v4:23.1.1'
}

My support Library version is 23.1.1; use your support library version as applicable.

If upload_file is meant to be the file, use:

files = {'upload_file': open('file.txt','rb')}
values = {'DB': 'photcat', 'OUT': 'csv', 'SHORT': 'short'}

r = requests.post(url, files=files, data=values)

and requests will send a multi-part form POST body with the upload_file field set to the contents of the file.txt file.

The filename will be included in the mime header for the specific field:

>>> import requests
>>> open('file.txt', 'wb')  # create an empty demo file
<_io.BufferedWriter name='file.txt'>
>>> files = {'upload_file': open('file.txt', 'rb')}
>>> print(requests.Request('POST', 'http://example.com', files=files).prepare().body.decode('ascii'))
--c226ce13d09842658ffbd31e0563c6bd
Content-Disposition: form-data; name="upload_file"; filename="file.txt"


--c226ce13d09842658ffbd31e0563c6bd--

Note the filename="file.txt" parameter.

You can use a tuple for the files mapping value, with between 2 and 4 elements, if you need more control. The first element is the filename, followed by the contents, and an optional content-type header value and an optional mapping of additional headers:

files = {'upload_file': ('foobar.txt', open('file.txt','rb'), 'text/x-spam')}

This sets an alternative filename and content type, leaving out the optional headers.

If you are meaning the whole POST body to be taken from a file (with no other fields specified), then don't use the files parameter, just post the file directly as data. You then may want to set a Content-Type header too, as none will be set otherwise. See Python requests - POST data from a file.

You may be overcomplicating things, is there any reason you need the stringr package?

 df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
 as.Date(df$Date, "%m/%d/%Y %H:%M:%S")

[1] "2009-10-09" "2009-10-15"

More generally and if you need the time component as well, use strptime:

strptime(df$Date, "%m/%d/%Y %H:%M:%S")

I'm guessing at what your actual data might look at from the partial results you give.

I use Eclipse under Fedora 20 with MinGW for cross compile. Use these settings and the program won't ask for libstdc++-6.dll any more.

The construction like this: $('[data-XXX=111]') isn't working in Safari 8.0.

If you set data attribute this way: $('div').data('XXX', 111), it only works if you set data attribute directly in DOM like this: $('div').attr('data-XXX', 111).

I think it's because jQuery team optimized garbage collector to prevent memory leaks and heavy operations on DOM rebuilding on each change data attribute.

In case of plotting time series, the command ts.plot requires a different argument than xaxt="n"

require(graphics)
ts.plot(ldeaths, mdeaths, xlab="year", ylab="deaths", lty=c(1:2), gpars=list(xaxt="n"))
axis(1, at = seq(1974, 1980, by = 2))

You have a JSON object that contains an Array. You need to access the array results. Change your code to:

this.data = res.json().results

str.erase(str.begin() + str.size() - 1)

str.erase(str.rbegin()) does not compile unfortunately, since reverse_iterator cannot be converted to a normal_iterator.

C++11 is your friend in this case.

toMap() in JSONObject works fine with nested objects and arrays already.

As the java.util.Map interface specifies to check the mappings and not the order, comparing the Maps is fine and also recursive.

json1 = new JSONObject("{...}");
json2 = new JSONObject("{...}");
json1.toMap().equals(json2.toMap());

It will work fine with any order and nested elements.

It will NOT however work with extra/ignored elements. If those are known you can remove them before calling equals on the maps.

Since you are loading in the spans via ajax you will have to attach delegate handlers to the events to catch them as they bubble up.

$(document).on('click','span',function(e){
    console.log(e.target.id)
})

you will want to attach the event to the closest static member you can to increase efficiency.

$('#main_div').on('click','span',function(e){
    console.log(e.target.id)
})

is better than binding to the document for instance.

This question may help you understand

Direct vs. Delegated - jQuery .on()

I tried the accepted answer and it works pretty well. Unfortunately the US Time Format appears to be H:MM:SS.CS, and the missing 0 on the front was causing parsing problems before 10 am. To get over this hurdle and also allow parsing of most any of the world time formats, I came up with this simple routine that appears to work quite well.

:ParseTime
rem The format of %%TIME%% is H:MM:SS.CS or (HH:MM:SS,CS) for example 0:01:23.45 or 23:59:59,99
FOR /F "tokens=1,2,3,4 delims=:.," %%a IN ("%1") DO SET /A "%2=(%%a * 360000) + (%%b * 6000) + (%%c * 100) + %%d"
GOTO :EOF

The nice thing with this routine is that you pass in the time string as the first parameter and the name of the environment variable you want to contain the time (in centiseconds) as the second parameter. For example:

CALL :ParseTime %START_TIME% START_CS
CALL :ParseTime %TIME% END_CS
SET /A DURATION=%END_CS% - %START_CS%

I had a fragment that was getting loaded-in after/by the main partial that came in via routing.

I needed to run a function after that subpartial loaded and I didn't want to write a new directive and figured out you could use a cheeky ngIf

Controller of parent partial:

$scope.subIsLoaded = function() { /*do stuff*/; return true; };

HTML of subpartial

<element ng-if="subIsLoaded()"><!-- more html --></element>

$_SERVER['HTTP_REFERER'] will give you incomplete url.

If you want http://bawse.3owl.com/jayz__magna_carta_holy_grail.php, $_SERVER['HTTP_REFERER'] will give you http://bawse.3owl.com/ only.

There are 3 ways to do this:

1. Define the Series names directly

Right-click on the Chart and click Select Data then edit the series names directly as shown below.

You can either specify the values directly e.g. Series 1 or specify a range e.g. =A2

2. Create a chart defining upfront the series and axis labels

Simply select your data range (in similar format as I specified) and create a simple bar chart. The labels should be defined automatically.

3. Define the legend (series names) using VBA

Similarly you can define the series names dynamically using VBA. A simple example below:

ActiveChart.ChartArea.Select
ActiveChart.FullSeriesCollection(1).Name = "=""Hello"""

This will redefine the first series name. Just change the index from (1) to e.g. (2) and so on to change the following series names. What does the VBA above do? It sets the series name to Hello as "=""Hello""" translates to ="Hello" (" have to be escaped by a preceding ").

df.withColumnRenamed('age', 'age2')

If your code cannot be updated on some reason, just change your switch ... continue to switch ... break, as in previous versions of PHP it was meant to work this way.
