An alternative is to use the Alpine Linux containers, e.g. python:2.7-alpine. They offer pip out of the box (and have a smaller footprint which leads to faster builds etc).

This method can be useful to validate date in PHP. Current method is for mm/dd/yyyy format. You have to update parameter sequence in checkdate as per your format and delimiter in explode .

    function isValidDate($dt)
    {
        $dtArr = explode('/', $dt);
        if (!empty($dtArr[0]) && !empty($dtArr[1]) && !empty($dtArr[2])) {
            return checkdate((int) $dtArr[0], (int) $dtArr[1], (int) $dtArr[2]);
        } else {
            return false;
        }
    }

This is an authentication issue. In my case, it solved by below steps: 1- Go to IIS manager, in the left pane, expand the server root and select your web application from Sites node. 2- In the Home screen, go to IIS section and select Authentication. 3- Enable Anonymous Authentication. 4- Then, select Edit and set Edit Anonymous Authentication Credentials to Application pool identity.

Try this, works in Ruby:

DateTime.now.to_time.utc

What I did to overcome this was sudo apt install python-pip.

It turned out my virtual machine did not have pip installed yet. It's conceivable that other people could have this scenario too.

You can try this instead:

mystring.replace(r' ','-')

I might be off here, but it seems that the answer is quite obvious: Look at reference paths in the project properties. In our setup I added our common repository folder, to the ref path GUI window, like so

That way I can copy my dlls (ready for publish) to this folder and every developer now gets the updated DLL every time it builds from this folder.

If the dll is found in the Solution, the builder should prioritize the local version over the published team version.

If you are looking to cobble together a quick utility with minimal effort, bash is good. For a wrapper round an application, bash is invaluable.

Anything that may have you coming back over and over to add improvements is probably (though not always) better suited to a language like Python as Bash code comprising over a 1000 lines gets very painful to maintain. Bash code is also irritating to debug when it gets long.......

Part of the problem with these kind of questions is, from my experience, that shell scripts are usually all custom tasks. There have been very few shell scripting tasks that I have come across where there is already a solution freely available.

The verbose option is handy, but if you want to see everything that curl does (including the HTTP body that is transmitted, and not just the headers), I suggest using one of the below options:

• --trace-ascii - # stdout
• --trace-ascii output_file.txt # file

I believe you intended it more this way:

foreach (DataTable table in ds.Tables)
{
    foreach (DataRow dr in table.Rows)
    {
        DateTime TaskStart = DateTime.Parse(dr["TaskStart"].ToString());
        TaskStart.ToString("dd-MMMM-yyyy");
        rpt.SetParameterValue("TaskStartDate", TaskStart);
    }
}

You always accessed your first row in your dataset.

Best way is to use variable.

var style1 = {
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
};
$("#message").css(style1);

Unless you need more than just the contents of the file, you could use file_get_contents.

$xml = file_get_contents("http://www.example.com/file.xml");

For anything more complex, I'd use cURL.

i think i am having a bit of confusion here. :) But seems no one else have ..

Are you asking which one to use in this scenario? If Yes then And is the correct answer.

If you are asking about how the operators are working, then

In php both AND, && and OR, || will work in the same way. If you are new in programming and php is one of your first languages them i suggest using AND and OR, because it increases readability and reduces confusion when you check back. But if you are familiar with any other languages already then you might already have familiarized the && and || operators.

Ultra-efficient Bit-boarding

Let's store the game in a binary integer, and evaluate everything using just one step!

• We know that X's moves occupy 9 bits: xxx xxx xxx
• We know that O's moves occupy 9 bits: ooo ooo ooo

So, a board position could be represented in just 18 bits: xoxoxo xoxoxo xoxoxo

But, whilst this might look efficient, it doesn't help us with determining a win. We need a more useful bit pattern... one that not only encodes the moves, but also encodes the rows, columns and diagonals in a reasonable way.

I would do this by using a clever integer value for each board position.

Choosing a more useful representation

First, we need a board notation, just so that we can discuss this. So, similar to Chess, lets number the rows with letters and the columns with numbers - so we know which square we're talking about

And let's give each a binary value.

a1 = 100 000 000 100 000 000 100 000 ; Row A Col 1 (top left corner)
a2 = 010 000 000 000 100 000 000 000 ; Row A Col 2 (top edge)
a3 = 001 000 000 000 000 100 000 100 ; Row A Col 3 (top right corner)
b1 = 000 100 000 010 000 000 000 000 ; Row B Col 1 (left edge)
b2 = 000 010 000 000 010 000 010 010 ; Row B Col 2 (middle square)
b3 = 000 001 000 000 000 010 000 000 ; Row B Col 4 (right edge)
c1 = 000 000 100 001 000 000 000 001 ; Row C Col 1 (bottom left corner)
c2 = 000 000 010 000 001 000 000 000 ; Row C Col 2 (bottom edge)
c3 = 000 000 001 000 000 001 001 000 ; Row C Col 3 (bottom right corner)

... where, the binary values encode which rows, columns and diagonals the position appears in. (we'll look at how this works this later)

We will use these values to build two representations of the game, one for X and one for O

• X starts with an empty board : 000 000 000 000 000 000 000 000
• O starts with an empty board : 000 000 000 000 000 000 000 000

Let's follow X's moves (O would be the same principle)

• X plays A1... so we OR (the X board) with value A1
• X plays A2... so we OR with value A2
• X plays A3... so we OR with value A3

What does that do to X's board value :

1. a1 = 100 000 000 100 000 000 100 000 ... ORed with
2. a2 = 010 000 000 000 100 000 000 000 ... ORed with
3. a3 = 001 000 000 000 000 100 000 100 ... equals :

XB = 111 000 000 100 100 100 100 100

Reading from left to right we see that X has :

• 111 (All positions) in Row 1 (\o/ A win, Yay!)
• 000 (No positions) in Row 2
• 000 (No positions) in Row 3
• 100 (One position) Only the first position of Column 1
• 100 (One position) Only the first position of Column 1
• 100 (One position) Only the first position of Column 1
• 100 (One position) Only the first position of Diagonal 1
• 100 (One position) Only the first position of Diagonal 2

You'll notice that whenever X (or O) has a winning line, then there will also be three consecutive bits in his board value. Precisely Where those three bits are, dictates which row/column/diagonal he won on.

So, the trick now is to find a way to check for this (three consecutive bits set) condition in a single operation.

Modifying the values to make detection easier

To assist with this, let's change our bit representation so that there are always ZEROs between the groups of three (Because 001 110 is also three consecutive bits - but they are NOT a valid win ... so, a fixed zero spacer would break these up: 0 001 0 110)

So, after adding some spacing ZEROes, we can be confident that ANY three consecutive set bits in X's or O's board value indicates a win!

So, our new binary values (with zero-padding) look like this :

• a1 = 100 0 000 0 000 0 100 0 000 0 000 0 100 0 000 0 ; 0x80080080 (hex)
• a2 = 010 0 000 0 000 0 000 0 100 0 000 0 000 0 000 0 ; 0x40008000
• a3 = 001 0 000 0 000 0 000 0 000 0 100 0 000 0 100 0 ; 0x20000808
• b1 = 000 0 100 0 000 0 010 0 000 0 000 0 000 0 000 0 ; 0x08040000
• b2 = 000 0 010 0 000 0 000 0 010 0 000 0 010 0 010 0 ; 0x04004044
• b3 = 000 0 001 0 000 0 000 0 000 0 010 0 000 0 000 0 ; 0x02000400
• c1 = 000 0 000 0 100 0 001 0 000 0 000 0 000 0 001 0 ; 0x00820002
• c2 = 000 0 000 0 010 0 000 0 001 0 000 0 000 0 000 0 ; 0x00402000
• c3 = 000 0 000 0 001 0 000 0 000 0 001 0 001 0 000 0 ; 0x00200220

You'll notice that each "winline" of the board now requires 4 bits.

8 winlines x 4 bits each = 32 bits! Isn't that convenient : )))))

Parsing

We could shift through all the bits looking for three consecutive bits, but that will take 32 shifts x 2 players... and a counter to keep track. It's slow!

We could AND with 0xF, looking for the value 8+4+2=14. And this would allow us to check 4 bits at a time. Cutting the number of shifts by a quarter. But again, this is slow!

So, instead, let's check ALL of the possibilities at once...

Ultra-efficient win detection

Imagine we wanted to evaluate the A3+A1+B2+C3 case (a win on the diagonal)

a1 = 100 0 000 0 000 0 100 0 000 0 000 0 100 0 000 0, OR
a3 = 001 0 000 0 000 0 000 0 000 0 100 0 000 0 100 0, OR
b2 = 000 0 010 0 000 0 000 0 010 0 000 0 010 0 010 0, OR
c3 = 000 0 000 0 001 0 000 0 000 0 001 0 001 0 000 0, =

XB = 101 0 010 0 001 0 100 0 010 0 101 0 111 0 110 0  (See the win, on Diagonal 1?)

Now, let's check it for a win, by efficiently merging three bits into one...

Simply use : XB AND (XB << 1) AND (XB >> 1) in other words: XB ANDed with (XB shifted left) AND (XB shiftted right)

Let's try an example...

10100100001010000100101011101100 ; whitespaces removed for easy shifting
(AND)
01001000010100001001010111011000 ; XB shifted left
(AND)
01010010000101000010010101110110 ; XB shifted left
(Equals)
00000000000000000000000001000000

See that? Any non-zero result means a win!

But, where did they win

Want to know where they won? Well, you could just use a second table :

0x40000000 = RowA
0x04000000 = RowB
0x00400000 = RowC
0x00040000 = Col1
0x00004000 = Col2
0x00000400 = Col3
0x00000040 = Diag1
0x00000004 = Diag2

However, we can be smarter than that, as the pattern is VERY regular!

For example, in assembly you can use BSF (Bit Scan Forward) to find the number of leading zeros. Then subtract 2 and then /4 (Shift Right 2) - to get a number between 0 and 8... which you can use as an index to look up into an array of win strings :

{"wins the top row", "takes the middle row!", ... "steals the diagonal!" }

This makes the whole game logic... from move checking, to board updating and right through to win/loss detection and an appropriate success message, all fit in a handful of ASM instructions.

... it's tiny, efficient and ultrafast!

Checking whether a move is playable

Obviously, ORing "X's board" with "O's board" = ALL POSITIONS

So, you can check if a move is valid quite easily. If user chooses UpperLeft, this position has an integer value. Just check the 'AND' of this Value with (XB OR OB)...

... if the result is nonzero, then the position is already in use.

Conclusion

If you're looking for efficient ways to process a board, don't start with a board object. Try to discover some useful abstraction.

See if the states fit within an integer, and think about what an 'easy' bitmask to process would look like. With some clever choice of integers to represent moves, positions or boards... you might find that the entire game can be played, evaluated and scored VERY efficiently - using simply bitwise logic.

Closing apologies

BTW I'm not a regular here on StackOverflow, so I hope this post wasn't too chaotic to follow. Also, please be kind... "Human" is my second language and I'm not quite fluent yet ;)

Anyway, I hope this helps someone.

This code from http://php.net/unlink:

/**
 * Delete a file or recursively delete a directory
 *
 * @param string $str Path to file or directory
 */
function recursiveDelete($str) {
    if (is_file($str)) {
        return @unlink($str);
    }
    elseif (is_dir($str)) {
        $scan = glob(rtrim($str,'/').'/*');
        foreach($scan as $index=>$path) {
            recursiveDelete($path);
        }
        return @rmdir($str);
    }
}

I think you can use SeriesGroupBy.nunique:

print (df.groupby('param')['group'].nunique())
param
a    2
b    1
Name: group, dtype: int64

Another solution with unique, then create new df by DataFrame.from_records, reshape to Series by stack and last value_counts:

a = df[df.param.notnull()].groupby('group')['param'].unique()
print (pd.DataFrame.from_records(a.values.tolist()).stack().value_counts())
a    2
b    1
dtype: int64

When you call notify() from an object t, java notifies a particular t.wait() method. But, how does java search and notify a particular wait method.

java only looks into the synchronized block of code which was locked by object t. java cannot search the whole code to notify a particular t.wait().

If you are using the new Toolbar, with the theme Theme.AppCompat.Light.NoActionBar, you can style it in the following way.

 <style name="ToolbarTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:textColorPrimary">@color/my_color1</item>
    <item name="android:textColorSecondary">@color/my_color2</item>
    <item name="android:textColor">@color/my_color3</item>
 </style>`

According to the results I got,
android:textColorPrimary is the text color displaying the name of your activity, which is the primary text of the toolbar.

android:textColorSecondary is the text color for subtitle and more options (3 dot) button. (Yes, it changed its color according to this property!)

android:textColor is the color for all other text including the menu.

Finally set the theme to the Toolbar

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:theme="@style/ToolbarTheme"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"/>

If you want to simply check single database size, you can do it using SSMS Gui

Under Chrome v51 on a Mac, I found the rendering settings by clicking in the upper right corner, choosing More tools > Rendering settings and checking the Emulate media button in the options offered at the bottom of the window.

Thank you to all the other posters that led me to this, and credit to those that provided the answer without the images.

Do not forget to initialize the output buffer. The first argument to strcat must be a null terminated string with enough extra space allocated for the resulting string:

char out[1024] = ""; // must be initialized
strcat( out, null_terminated_string ); 
// null_terminated_string has less than 1023 chars

For sort on multiple array object field. Enter your field name in arrprop array like ["a","b","c"] then pass in second parameter arrsource actual source we want to sort.

function SortArrayobject(arrprop,arrsource){
arrprop.forEach(function(i){
arrsource.sort(function(a,b){
return ((a[i] < b[i]) ? -1 : ((a[i] > b[i]) ? 1 : 0));
});
});
return arrsource;
}

The CSS :active state means the active state of the clicked link - the moment when you clicked on it, but not released the mouse button yet, for example. It doesn't know which page you're on and can't apply any styles to the menu items.

To fix your problem you have to create a class and add it manually to the current page's menu:

a.active { color: #f00 }

<ul>
    <li><a href="index.php" class="active">HOME</a></li>
    <li><a href="two.php">PORTFOLIO</a></li>
    <li><a href="three.php">ABOUT</a></li>
    <li><a href="four.php">CONTACT</a></li>
    <li><a href="five.php">SHOP</a></li>
</ul>

if menu html is

<div id="nav-main" class="nav-collapse collapse">
     <ul class="nav">
         <li>
             <a href='#somewhere'>Somewhere</a>
         </li>
     </ul>
</div>

on nav toggle 'in' class is added and removed from the toggle. check if responsive menu is opened then perform the close toggle.

$('.nav-collapse .nav a').on('click', function(){
    if ( $( '.nav-collapse' ).hasClass('in') ) {
        $('.navbar-toggle').click();
    }
});

You have to change the values in the CATALINA_OPTS option defined in the Tomcat Catalina start file. To increase the PermGen memory change the value of the MaxPermSize variable, otherwise change the value of the Xmx variable.

Linux & Mac OS: Open or create setenv.sh file placed in the "bin" directory. You have to apply the changes to this line:

export CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"

Windows:

Open or create the setenv.bat file placed in the "bin" directory:

set CATALINA_OPTS=-server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

Use:

document.location.href = "http://yoursite.com" + document.getElementById('somefield');

That would get the value of some text field or hidden field, and add it to your site URL to get a new URL (href). You can modify this to suit your needs.

I have found that the VT char is used in pptx text boxes at the end of each line shown in the box in oder to adjust the text to the size of the box. It seems to be automatically generated by powerpoint (not introduced by the user) in order to move the text to the next line and fix the complete text block to the text box. In the example below, in the position of §:

"This is a text §
inside a text box"

Here's the magic you want:

    autocomplete="new-password"

Chrome intentionally ignores autocomplete="off" and autocomplete="false". However, they put new-password in as a special clause to stop new password forms from being auto-filled.

I put the above line in my password input, and now I can edit other fields in my form and the password is not auto-filled.

For angular 4+ versions you can try

<input [readonly]="true" type="date" name="date" />

Most solutions here tell you how to use a placeholder integer to represent nulls. That approach isn't helpful if you're uncertain that integer won't show up in your source data though. My method with will format floats without their decimal values and convert nulls to None's. The result is an object datatype that will look like an integer field with null values when loaded into a CSV.

In the beautifulsoup source this line allows divs to be nested within divs; so your concern in lukas' comment wouldn't be valid.

NESTABLE_BLOCK_TAGS = ['blockquote', 'div', 'fieldset', 'ins', 'del']

What I think you need to do is to specify the attrs you want such as

source.find('div', attrs={'id':'articlebody'})

Set the height of the parent element, and give that the width. Then use a background image with the rule "background-size: cover"

    .parent {
       background-image: url(../img/team/bgteam.jpg);
       background-repeat: no-repeat;
       background-position: center center;
       -webkit-background-size: cover;
       background-size: cover;
    }

In my case over time I had saved a bunch of versions of myfile as myfile_bak, myfile_old, myfile_2010, backups/myfile etc. I wanted to put myfile's history in git using their modification dates. So rename the oldest to myfile, git add myfile, then git commit --date=(modification date from ls -l) myfile, rename next oldest to myfile, another git commit with --date, repeat...

To automate this somewhat, you can use shell-foo to get the modification time of the file. I started with ls -l and cut, but stat(1) is more direct

git commit --date="`stat -c %y myfile`" myfile

This worked for me

if (assoc_pagine[var] != undefined) {

instead this

if (assoc_pagine[var] != "undefined") {

In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that + returned a non-const value, and you could write:

(a + b).expensive();

In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.

In summary, there is a rationale for this practice, but it is essentially obsolete.

This can be done with a CSS hack (see the other answers), but it can also be done very easily with JavaScript.

Set the div's width to (for example) 50%, use JavaScript to check its width, and then set the height accordingly. Here's a code example using jQuery:

$(function() {_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
});

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

If you want the box to scale with the browser window on resize, move the code to a function and call it on the window resize event. Here's a demonstration of that too (view example full screen and resize browser window):

$(window).ready(updateHeight);_x000D_
$(window).resize(updateHeight);_x000D_
_x000D_
function updateHeight()_x000D_
{_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
}

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

Depending on why you are doing this, using a std::set might be a better idea than std::vector.

It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.

This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.

The representation of pointers is irrelevant to comparing them, since all comparisons in C take place as values not representations. The only way to compare the representation would be something hideous like:

SOAP web service always make a POST operation whereas using REST you can choose specific HTTP methods like GET, POST, PUT, and DELETE.

Example: to get an item using SOAP you should create a request XML, but in the case of REST you can just specify the item id in the URL itself.

I have similar requirement where I need a MySQL client but not server (running in a virtual machine and don't want any additional overhead) and for me the easiest thing was to install MySQL community server taking typical installation options but NOT configure the server, so it never starts, never runs. Added C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin to system path environment variable and I'm able to use the MySQL command line client mssql.exe and mysqladmin.exe programs.

weights.reshape(a, b) will return a new tensor with the same data as weights with size (a, b) as in it copies the data to another part of memory.

weights.resize_(a, b) returns the same tensor with a different shape. However, if the new shape results in fewer elements than the original tensor, some elements will be removed from the tensor (but not from memory). If the new shape results in more elements than the original tensor, new elements will be uninitialized in memory.

weights.view(a, b) will return a new tensor with the same data as weights with size (a, b)

To delete the last element of the lists, you could use:

def deleteLast(self):
    if self.Ans:
        del self.Ans[-1]
    if self.masses:
        del self.masses[-1]

Well, since an UUID gets added the hyphens (dashes) on toString() we can steal the implementation from Java's own implementation, shorting the byte array to 32 and adjusting the offset.

        public static String special() {
            UUID uuid = UUID.randomUUID();
            return fastUUID(uuid.getLeastSignificantBits(), uuid.getMostSignificantBits());
        }

        private static String fastUUID(long lsb, long msb) {
            byte[] buf = new byte[32];
            formatUnsignedLong0(lsb,        4, buf, 20, 12);
            formatUnsignedLong0(lsb >>> 48, 4, buf, 16, 4);

            formatUnsignedLong0(msb,        4, buf, 12, 4);
            formatUnsignedLong0(msb >>> 16, 4, buf, 8,  4);
            formatUnsignedLong0(msb >>> 32, 4, buf, 0,  8);

            return new String(buf, 0);
        }

        private static final char[] digits = {
                '0' , '1' , '2' , '3' , '4' , '5' ,
                '6' , '7' , '8' , '9' , 'a' , 'b' ,
                'c' , 'd' , 'e' , 'f' , 'g' , 'h' ,
                'i' , 'j' , 'k' , 'l' , 'm' , 'n' ,
                'o' , 'p' , 'q' , 'r' , 's' , 't' ,
                'u' , 'v' , 'w' , 'x' , 'y' , 'z'
        };
        private static void formatUnsignedLong0(long val, int shift, byte[] buf, int offset, int len) {
            int charPos = offset + len;
            int radix = 1 << shift;
            int mask = radix - 1;
            do {
                buf[--charPos] = (byte)digits[((int) val) & mask];
                val >>>= shift;
            } while (charPos > offset);
        }

Running it:

        public static void main(String[] args) {
            IntStream.range(0, 100).forEach(i-> {
                System.out.println(special());
            });
        }

Should be just as efficient (more effecient) than Javas actually.

Don't need a cursor... a while loop is sufficient.

------------------------------
-- Setup
------------------------------

DECLARE @Source TABLE
(
  id int,
  Name varchar(30),
  Value int
)

DECLARE @Target TABLE
(
  id int,
  Result varchar(max) 
)


INSERT INTO @Source(id, Name, Value) SELECT 1, 'A', 4
INSERT INTO @Source(id, Name, Value) SELECT 1, 'B', 8
INSERT INTO @Source(id, Name, Value) SELECT 2, 'C', 9


------------------------------
-- Technique
------------------------------

INSERT INTO @Target (id)
SELECT id
FROM @Source
GROUP BY id

DECLARE @id int, @Result varchar(max)
SET @id = (SELECT MIN(id) FROM @Target)

WHILE @id is not null
BEGIN
  SET @Result = null

  SELECT @Result =
    CASE
      WHEN @Result is null
      THEN ''
      ELSE @Result + ', '
    END + s.Name + ':' + convert(varchar(30),s.Value)
  FROM @Source s
  WHERE id = @id

  UPDATE @Target
  SET Result = @Result
  WHERE id = @id

  SET @id = (SELECT MIN(id) FROM @Target WHERE @id < id)
END

SELECT *
FROM @Target

I found this plugin to be doing what I was expecting: gulp-using

Simple usage example: Search all files in project with .jsx extension

gulp.task('reactify', function(){
        gulp.src(['../**/*.jsx']) 
            .pipe(using({}));
        ....
    });

Output:

[gulp] Using gulpfile /app/build/gulpfile.js
[gulp] Starting 'reactify'...
[gulp] Finished 'reactify' after 2.92 ms
[gulp] Using file /app/staging/web/content/view/logon.jsx

Taking a few of the best rated answers, I combined and made an ES6 function that passes eslinter.

export const formatMoney = (
  amount,
  decimalCount = 2,
  decimal = '.',
  thousands = ',',
  currencySymbol = '$',
) => {
  if (typeof Intl === 'object') {
    return new Intl.NumberFormat('en-AU', {
      style: 'currency',
      currency: 'AUD',
    }).format(amount);
  }
  // fallback if Intl is not present.
  try {
    const negativeSign = amount < 0 ? '-' : '';
    const amountNumber = Math.abs(Number(amount) || 0).toFixed(decimalCount);
    const i = parseInt(amountNumber, 10).toString();
    const j = i.length > 3 ? i.length % 3 : 0;
    return (
      currencySymbol +
      negativeSign +
      (j ? i.substr(0, j) + thousands : '') +
      i.substr(j).replace(/(\d{3})(?=\d)/g, `$1${thousands}`) +
      (decimalCount
        ? decimal +
          Math.abs(amountNumber - i)
            .toFixed(decimalCount)
            .slice(2)
        : '')
    );
  } catch (e) {
    // eslint-disable-next-line no-console
    console.error(e);
  }
  return amount;
};

Another important thing to consider from my experience..

I would strongly advice NOT to maximize maxBufferPoolSize, because buffers from the pool are never released until the app-domain (ie the Application Pool) recycles.

A period of high traffic could cause a lot of memory to be used and never released.

Unfortunately, it appears that we can't post shares for individual topics or articles within a page. It appears Facebook just wants us to share entire pages (based on url only).

There's also their new share dialog, but even though they claim it can do all of what the old sharer.php could do, that doesn't appear to be true.

And here's Facebooks 'best practices' for sharing.

Yes, datepicker supports max date property.

 $("#datepickeraddcustomer").datepicker({  
             dateFormat: "yy-mm-dd",  
             maxDate: new Date()  
        });

Have you tried to set the value of the static DefaultConnectionLimit property programmatically?

This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.

Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:

http://pauljacobson.org/2010/01/22/2010122firefox-and-its-limited-html-5-video-support-html/

You can also access them as an array elements, for example if you don't want to iterate through all of them

argc=$#
argv=("$@")

for (( j=0; j<argc; j++ )); do
    echo "${argv[j]}"
done

Try using this. It is the fastest and best ffmpeg-way I have figure it out:

 ffmpeg -ss 00:01:00 -i input.mp4 -to 00:02:00 -c copy output.mp4

This command trims your video in seconds!

Explanation of the command:

-i: This specifies the input file. In that case, it is (input.mp4).
-ss: Used with -i, this seeks in the input file (input.mp4) to position.
00:01:00: This is the time your trimmed video will start with.
-to: This specifies duration from start (00:01:40) to end (00:02:12).
00:02:00: This is the time your trimmed video will end with.
-c copy: This is an option to trim via stream copy. (NB: Very fast)

The timing format is: hh:mm:ss

Please note that the current highly upvoted answer is outdated and the trim would be extremely slow. For more information, look at this official ffmpeg article.

I may have a workaround.

Was having the same issue, where I am loading lots of items (via the file system) into a ListView via an AsyncTask. Had the onPreExecute() firing up a ProgressDialog, and then both onPostExecute() and onCancelled() (called when the task is cancelled explicitly via AsyncTask.cancel()) closing it via .cancel().

Got the same "java.lang.IllegalArgumentException: View not attached to window manager" error when I was killing the dialog in the onCancelled() method of the AsyncTask (I'd seen this done in the excellent Shelves app).

The workaround was to create a public field in the AsyncTask that contains the ProgressDialog:

public ProgressDialog mDialog;

Then, in onDestroy() when I cancel my AsyncTask, I can also kill the associated dialog via:

AsyncTask.mDialog.cancel();

Calling AsyncTask.cancel() DOES trigger onCancelled() in the AsyncTask, but for some reason by the time that method is called, the View has already been destroyed and thus cancelling the dialog is failing.

Others are suggesting a wrapping div but you should be able to do this without adding complexity to your html...

check this out:

  padding: 8px;
}

There is a Headers property in the HttpRequestMessage class. You can add custom headers there, which will be sent with each HTTP request. The DefaultRequestHeaders in the HttpClient class, on the other hand, sets headers to be sent with each request sent using that client object, hence the name Default Request Headers.

Hope this makes things more clear, at least for someone seeing this answer in future.

The accepted answer fails when trying to repeat deleting words, try this solution instead:

" delete current word, insert and normal modes
inoremap <C-BS> <C-O>b<C-O>dw
noremap <C-BS> bdw

It maps CTRL-BackSpace, also working in normal mode.

1. Will "length" ever deviate from the real length of "s". If the answer is no, then you don't need to store length, because strings store their length already, and you can just call s.Length.

2. To get the syntax you asked for, you can implement an "implicit" operator like so:

   static implicit operator MyStruct(string s) {
       return new MyStruct(...);
   }
   

3. The implicit operator will work, regardless of whether you make your struct mutable or not.

I had your issue and got it working again (on windows 7).

My setup had actually worked at first. I installed postgres and then set up the system PATH variables with C:\Program Files\PostgreSQL\9.6\bin; C:\Program Files\PostgreSQL\9.6\lib. The psql keyword in the command line gave no errors.

I deleted the PATH variables above one at a time to test if they were both really needed. Psql continued to work after I deleted the lib path, but stopped working after I deleted the bin path. When I returned bin, it still didn't work, and the same with lib. I closed and reopened the command line between tries, and checked the path. The problem lingered even though the path was identical to how it had been when working. I re-pasted it.

I uninstalled and reinstalled postgres. The problem lingered. It finally worked after I deleted the spaces between the "; C:..." in the paths and re-saved.

Not sure if it was really the spaces that were the culprit. Maybe the environment variables just needed to be altered and refreshed after the install.

I'm also still not sure if both lib and bin paths are needed since there seems to be some kind of lingering memory for old path configurations. I don't want to test it again though.

var sizef = document.getElementById('input-file-id').files[0].size;
                if(sizef > 210000){
                    alert('sorry error');
                }else {
                    //action
                }   

Important difference between setting Classpath in Windows and Linux is path separator which is ";" (semi-colon) in Windows and ":" (colon) in Linux. Also %PATH% is used to represent value of existing path variable in Windows while ${PATH} is used for same purpose in Linux (in the bash shell). Here is the way to setup classpath in Linux:

export CLASSPATH=${CLASSPATH}:/new/path

but as such Classpath is very tricky and you may wonder why your program is not working even after setting correct Classpath. Things to note:

1. -cp options overrides CLASSPATH environment variable.
2. Classpath defined in Manifest file overrides both -cp and CLASSPATH envorinment variable.

Reference: How Classpath works in Java.

<activity android:name="[packagename optional].ActivityClassName"></activity>

Simply adding the activity which we want to switch to should be placed in the manifest file

That message isn't actually an error - it's just a warning that the file in question isn't of the right architecture (e.g. 32-bit vs 64-bit, wrong CPU architecture). The linker will keep looking for a library of the right type.

Of course, if you're also getting an error along the lines of can't find lPI-Http then you have a problem :-)

It's hard to suggest what the exact remedy will be without knowing the details of your build system and makefiles, but here are a couple of shots in the dark:

1. Just to check: usually you would add flags to CFLAGS rather than CTAGS - are you sure this is correct? (What you have may be correct - this will depend on your build system!)
2. Often the flag needs to be passed to the linker too - so you may also need to modify LDFLAGS

If that doesn't help - can you post the full error output, plus the actual command (e.g. gcc foo.c -m32 -Dxxx etc) that was being executed?

lbl.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl.textColor = .white
lbl.backgroundColor = .lightGray//If required
lbl.font = UIFont.systemFont(ofSize: 17)

//To display multiple lines in label
lbl.numberOfLines = 0 //If you want to display only 2 lines replace 0(Zero) with 2.
lbl.lineBreakMode = .byWordWrapping //Word Wrap
// OR
lbl.lineBreakMode = .byCharWrapping //Charactor Wrap

lbl.sizeToFit()//If required
yourView.addSubview(lbl)

If you have multiple labels in your class use extension to add properties.

//Label 1
let lbl1 = UILabel(frame: CGRect(x: 10, y: 50, width: 230, height: 21))
lbl1.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl1.myLabel()//Call this function from extension to all your labels
view.addSubview(lbl1)

//Label 2
let lbl2 = UILabel(frame: CGRect(x: 10, y: 150, width: 230, height: 21))
lbl2.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl2.myLabel()//Call this function from extension to all your labels
view.addSubview(lbl2)

extension UILabel {
    func myLabel() {
        textAlignment = .center
        textColor = .white
        backgroundColor = .lightGray
        font = UIFont.systemFont(ofSize: 17)
        numberOfLines = 0
        lineBreakMode = .byCharWrapping
        sizeToFit()
    }
}

I always use 010 Editor to open huge files. It can handle 2 GB easily. I was manipulating files with 50 GB with 010 Editor :-)

It's commercial now, but it has a trial version.

An inner class, by definition, cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?"

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.

public var appVersionNumberString: String {
    get {
        return Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
    }
}

The @Qualifier annotation is used to resolve the autowiring conflict, when there are multiple beans of same type.

The @Qualifier annotation can be used on any class annotated with @Component or on methods annotated with @Bean. This annotation can also be applied on constructor arguments or method parameters.

Ex:-

public interface Vehicle {
     public void start();
     public void stop();
}

There are two beans, Car and Bike implements Vehicle interface

@Component(value="car")
public class Car implements Vehicle {

     @Override
     public void start() {
           System.out.println("Car started");
     }

     @Override
     public void stop() {
           System.out.println("Car stopped");
     }
 }

@Component(value="bike")
public class Bike implements Vehicle {

     @Override
     public void start() {
          System.out.println("Bike started");
     }

     @Override
     public void stop() {
          System.out.println("Bike stopped");
     }
}

Injecting Bike bean in VehicleService using @Autowired with @Qualifier annotation. If you didn't use @Qualifier, it will throw NoUniqueBeanDefinitionException.

@Component
public class VehicleService {

    @Autowired
    @Qualifier("bike")
    private Vehicle vehicle;

    public void service() {
         vehicle.start();
         vehicle.stop();
    }
}

Reference:- @Qualifier annotation example

I prefer using standard converters:

#include <codecvt>

std::string s = "Hi";
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
std::wstring wide = converter.from_bytes(s);
LPCWSTR result = wide.c_str();

Please find more details in this answer: https://stackoverflow.com/a/18597384/592651

Update 12/21/2020 : My answer was commented on by @Andreas H . I thought his comment is valuable, so I updated my answer accordingly:

1. codecvt_utf8_utf16 is deprecated in C++17.
2. Also the code implies that source encoding is UTF-8 which it usually isn't.
3. In C++20 there is a separate type std::u8string for UTF-8 because of that.

But it worked for me because I am still using an old version of C++ and it happened that my source encoding was UTF-8 .

I have found a way to do this...

Create a batch file to open your script:

@echo off
START "" "C:\Scripts\ScriptName.ps1"

Then create a shortcut, on your desktop say (right click New -> Shortcut).

Then paste this into the location:

C:\Windows\System32\runas.exe /savecred /user:*DOMAIN*\*ADMIN USERNAME* C:\Scripts\BatchFileName.bat

When first opening, you will have to enter your password once. This will then save it in the Windows credential manager.

After this you should then be able to run as administrator without having to enter a administrator username or password.

Found a way to do this, simply add a querystring to load your components, like so:

@Component({
  selector: 'some-component',
  templateUrl: `./app/component/stuff/component.html?v=${new Date().getTime()}`,
  styleUrls: [`./app/component/stuff/component.css?v=${new Date().getTime()}`]
})

This should force the client to load the server's copy of the template instead of the browser's. If you would like it to refresh only after a certain period of time you could use this ISOString instead:

new Date().toISOString() //2016-09-24T00:43:21.584Z

And substring some characters so that it will only change after an hour for example:

new Date().toISOString().substr(0,13) //2016-09-24T00

Hope this helps

Suppose you are designing a new class with some methods that you don't want to implement, yet.

class MyClass(object):
    def meth_a(self):
        pass

    def meth_b(self):
        print "I'm meth_b"

If you were to leave out the pass, the code wouldn't run.

You would then get an:

IndentationError: expected an indented block

To summarize, the pass statement does nothing particular, but it can act as a placeholder, as demonstrated here.

You have to first escape the backslash because it's a literal (yielding \\), and then escape it again because of the regular expression (yielding \\\\). So, Try:

 s.replaceAll("'", "\\\\'");

output:

You\'ll be totally awesome, I\'m really terrible

You may also try standard sql un-pivoting method by using a sequence of logic with the following code.. The following code has 3 steps:

1. create multiple copies for each row using cross join (also creating subject column in this case)
2. create column "marks" and fill in relevant values using case expression ( ex: if subject is science then pick value from science column)

3. remove any null combinations ( if exists, table expression can be fully avoided if there are strictly no null values in base table)

    select *
    from 
    (
       select name, subject,
       case subject
       when 'Maths' then maths
       when 'Science' then science
       when 'English' then english
       end as Marks
   from studentmarks
   Cross Join (values('Maths'),('Science'),('English')) AS Subjct(Subject)
   )as D
   where marks is not null;
   

I used a proxy url to solve a similar problem when I want to post data to my apache solr hosted in another server. (This may not be the perfect answer but it solves my problem.)

Follow this URL: Using Mode-Rewrite for proxying, I add this line to my httpd.conf:

 RewriteRule ^solr/(.*)$ http://ip:8983/solr$1 [P]

Therefore, I can just post data to /solr instead of posting data to http://ip:8983/solr/*. Then it will be posting data in the same origin.

Thanks to https://stackoverflow.com/users/1652962/cimmanon that gave me the answer.

The solution is setting a height to the vertical scrollable element. For example:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    height: 0px;
}

The element will have height because flexbox recalculates it unless you want a min-height so you can use height: 100px; that it is exactly the same as: min-height: 100px;

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    height: 100px; /* == min-height: 100px*/
}

So the best solution if you want a min-height in the vertical scroll:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    min-height: 100px;
}

If you just want full vertical scroll in case there is no enough space to see the article:

#container article {
    flex: 1 1 auto;
    overflow-y: auto;
    min-height: 0px;
}

The final code: http://jsfiddle.net/ch7n6/867/

It appears the problem is that a user created via the method described in the mongo docs does not have permission to connect to the default database (test), even if that user was created with the "userAdminAnyDatabase" and "dbAdminAnyDatabase" roles.

Another pure Bash solution:

while IFS=':' read a b ; do
  echo "$a"
done < "$infile" > "$outfile"

All these keywords try, catch and throw are related to the exception handling concept in java. An exception is an event that occurs during the execution of programs. Exception disrupts the normal flow of an application. Exception handling is a mechanism used to handle the exception so that the normal flow of application can be maintained. Try-catch block is used to handle the exception. In a try block, we write the code which may throw an exception and in catch block we write code to handle that exception. Throw keyword is used to explicitly throw an exception. Generally, throw keyword is used to throw user defined exceptions.

Firstly, easiest way to one hot encode: use Sklearn.

http://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.OneHotEncoder.html

Secondly, I don't think using pandas to one hot encode is that simple (unconfirmed though)

Creating dummy variables in pandas for python

Lastly, is it necessary for you to one hot encode? One hot encoding exponentially increases the number of features, drastically increasing the run time of any classifier or anything else you are going to run. Especially when each categorical feature has many levels. Instead you can do dummy coding.

Using dummy encoding usually works well, for much less run time and complexity. A wise prof once told me, 'Less is More'.

Here's the code for my custom encoding function if you want.

from sklearn.preprocessing import LabelEncoder

#Auto encodes any dataframe column of type category or object.
def dummyEncode(df):
        columnsToEncode = list(df.select_dtypes(include=['category','object']))
        le = LabelEncoder()
        for feature in columnsToEncode:
            try:
                df[feature] = le.fit_transform(df[feature])
            except:
                print('Error encoding '+feature)
        return df

EDIT: Comparison to be clearer:

One-hot encoding: convert n levels to n-1 columns.

Index  Animal         Index  cat  mouse
  1     dog             1     0     0
  2     cat       -->   2     1     0
  3    mouse            3     0     1

You can see how this will explode your memory if you have many different types (or levels) in your categorical feature. Keep in mind, this is just ONE column.

Dummy Coding:

Index  Animal         Index  Animal
  1     dog             1      0   
  2     cat       -->   2      1 
  3    mouse            3      2

Convert to numerical representations instead. Greatly saves feature space, at the cost of a bit of accuracy.

I prefer len([b for b in boollist if b is True]) (or the generator-expression equivalent), as it's quite self-explanatory. Less 'magical' than the answer proposed by Ignacio Vazquez-Abrams.

Alternatively, you can do this, which still assumes that bool is convertable to int, but makes no assumptions about the value of True: ntrue = sum(boollist) / int(True)

For those running wamp mysql server

Wamp tray Icon -> MySql -> my.ini

[wampmysqld]
port        = 3306
socket      = /tmp/mysql.sock
key_buffer_size = 16M
max_allowed_packet = 16M        // --> changing this wont solve
sort_buffer_size = 512K

Scroll down to the end until u find

[mysqld]
port=3306
explicit_defaults_for_timestamp = TRUE

Add the line of packet_size in between

[mysqld]
port=3306
max_allowed_packet = 16M
explicit_defaults_for_timestamp = TRUE

Check whether it worked with this query

Select @@global.max_allowed_packet;

From the docs:

To uninstall Anaconda open a terminal window and remove the entire anaconda install directory: rm -rf ~/anaconda. You may also edit ~/.bash_profile and remove the anaconda directory from your PATH environment variable, and remove the hidden .condarc file and .conda and .continuum directories which may have been created in the home directory with rm -rf ~/.condarc ~/.conda ~/.continuum.

Further notes:

• Python3 installs may use a ~/anaconda3 dir instead of ~/anaconda.
• You might also have a ~/.anaconda hidden directory that may be removed.
• Depending on how you installed, it is possible that the PATH is modified in one of your runcom files, and not in your shell profile. So, for example if you are using bash, be sure to check your ~/.bashrc if you don't find the PATH modified in ~/.bash_profile.

Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:

1. Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)

2. Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.

3. Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.

4. Mash the build button.

Run cscript.exe for full command args, I think

cscript //X scriptfile.vbs MyArg1 MyArg2

will run the script in a debugger.

Semantics.... generally a website contains static HTML pages and a web application performs some type of work. For example, a website for a realtor may give information about the realtor, where a web application for the realtor may list current properties and manage the contact information for the realtor themselves.

You'll have to actually USE jQuery to build the div, if you want to write maintainable or usable code.

//create a div
var $newDiv = $('<div>');

//set the id
$newDiv.attr("id","myId");

If you are pushing from one remote origin to another, you can use this:

git push newremote refs/remotes/oldremote/*:refs/heads/*

This worked for me. Reffer to this: https://www.metaltoad.com/blog/git-push-all-branches-new-remote

If you will change the order of operations, you will avoid the strange behavior: First insert the value to the right place in the list, and then delete it from his first position. Make sure you delete it by his index, because if you will delete it by reference, you might delete them both...

This question is pretty old, but it still seems important, as it isn't easy to put relative references from readme.md to wiki pages on Github.

I played around a little bit and this relative link seems to work pretty well:

[Your wiki page](../../wiki/your-wiki-page)

The two ../ will remove /blob/master/ and use your base as a starting point. I haven't tried this on other repositories than Github, though (there may be compatibility issues).

I also got this exact error log on my AWS EC2 instance.

There were no connection leaks since I was just deploying the alpha application (no real users), and I confirmed with Activity Monitor and sp_who that there are in fact no connections to the database.

My issue was AWS related - more specifically, with the Security Groups. See, only certain security groups had access to the RDS server where I hosted the database. I added an ingress rule with authorize-security-group-ingress command to allow access to the correct EC2 instance to the RDS server by using --source-group-name parameter. The ingress rule was added, I could see that on the AWS UI - but I got this error.

When I removed and then added the ingress rule manually on AWS UI - suddenly the exception was no more and the app was working.

The ASP.NET Core way is now here:

[HttpPost("UploadFiles")]
public async Task<IActionResult> Post(List<IFormFile> files)
{
    long size = files.Sum(f => f.Length);

    // full path to file in temp location
    var filePath = Path.GetTempFileName();

    foreach (var formFile in files)
    {
        if (formFile.Length > 0)
        {
            using (var stream = new FileStream(filePath, FileMode.Create))
            {
                await formFile.CopyToAsync(stream);
            }
        }
    }

    // process uploaded files
    // Don't rely on or trust the FileName property without validation.

    return Ok(new { count = files.Count, size, filePath});
}

Google Map V2

The following solution works for Android Marshmallow 6 (API 23, API 24, API 25, API 26, API 27, API 28). It also works in Xamarin.

LatLngBounds.Builder builder = new LatLngBounds.Builder();

//the include method will calculate the min and max bound.
builder.include(marker1.getPosition());
builder.include(marker2.getPosition());
builder.include(marker3.getPosition());
builder.include(marker4.getPosition());

LatLngBounds bounds = builder.build();

int width = getResources().getDisplayMetrics().widthPixels;
int height = getResources().getDisplayMetrics().heightPixels;
int padding = (int) (width * 0.10); // offset from edges of the map 10% of screen

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);

mMap.animateCamera(cu);

Maybe something like this:

sed 's/ab/~~/g; s/bc/ab/g; s/~~/bc/g'

Replace ~ with a character that you know won't be in the string.

You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.

So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filters.

As trivial as it may be, I had to restart Windows when faced with this problem.

I am running Windows 7 x64. I did a manual update to the system PATH variable. This worked okay if I ran cmd.exe from the stat menu. But if I type "cmd" in the Windows Explorer address bar, it seems to load the PATH from elsewhere, which doesn't have my manual changes.

(To avoid doubt - yes, I did close and rerun cmd a couple of times before I restarted and it didn't help.)

I am not allowed to comment to pkyeck's response which did not work for a few people including me, so I am adding a separate comment in continuation to his response:

Basically try to add the variable which he has mentioned in the .profile file if the .bash_profile did not work. It is located in your home directory and then restart the terminal. that got it working for me.

The obvious blocker would be that you do not have an access to edit the .profile file, for which use the "touch" to check the access and the "sudo" command to get the access

1. touch .profile

2. vi .profile

Here are the variable pkyeck suggests that we added as a solution which worked with editing .profile for me:

1. export M2_HOME=/apache-maven-3.3.3

2. export PATH=$PATH:$M2_HOME/bin

The second div is position: static (the default) so the z-index does not apply to it.

You need to position (set the position property to anything other than static, you probably want relative in this case) anything you want to give a z-index to.

You can also switch environments in Anaconda Navigator, install Jupiter and run it.

Using a Messenger is another simple way to communicate between a Service and an Activity.

In the Activity, create a Handler with a corresponding Messenger. This will handle messages from your Service.

class ResponseHandler extends Handler {
    @Override public void handleMessage(Message message) {
            Toast.makeText(this, "message from service",
                    Toast.LENGTH_SHORT).show();
    }
}
Messenger messenger = new Messenger(new ResponseHandler());

The Messenger can be passed to the service by attaching it to a Message:

Message message = Message.obtain(null, MyService.ADD_RESPONSE_HANDLER);
message.replyTo = messenger;
try {
    myService.send(message);
catch (RemoteException e) {
    e.printStackTrace();
}

A full example can be found in the API demos: MessengerService and MessengerServiceActivity. Refer to the full example for how MyService works.

this one is working for me also for internet explorer:

<div class="col imagebox" [ngStyle]="bkUrl"></div>

...

@Input() background = '571x450img';  
bkUrl = {};   
ngOnInit() {
    this.bkUrl = this.getBkUrl();
  }
getBkUrl() {
    const styles = {
      'background-image': 'url(src/assets/images/' + this.background + '.jpg)'
    };
    console.log(styles);
    return styles;
  }

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

Try the following:

if ((select VisitCount from PageImage where PID=@pid and PageNumber=5) is NULL)
begin
    update PageImage
    set VisitCount=1
    where PID=@pid and PageNumber=@pageno
end 
else
begin
    update PageImage 
    set VisitCount=VisitCount+1
    where PID=@pid and PageNumber=@pageno
end

Verified: it works well in Docker 1.7.0.

Don't specify --pull=true when running the docker build command

From this thread on reference locally-built image using FROM at dockerfile:

If you want use the local image as the base image, pass without the option --pull=true
--pull=true will always attempt to pull a newer version of the image.

You should not pass the call function hi() to the loop() function, This will give the result.

def hi():     
  print('hi')

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)            # Do not use hi() function inside loop() function

You can use the getimagesize function like this:

list($width, $height) = getimagesize('path to image');
echo "width: " . $width . "<br />";
echo "height: " .  $height;

From my experience with tutorials, and other things number 2 always seems preferred, but it's a personal preference choice more than anything else.

Try to trigger() event in your function:

$("form").trigger('submit'); // and then... do submit()

You can also define these chars as list of string. Then you can check if the characters is valid for accepted characters with list.Contains(x) method.

First of all you should know the difference between a virtual and abstract method.

Abstract Method

• Abstract Method resides in abstract class and it has no body.
• Abstract Method must be overridden in non-abstract child class.

Virtual Method

• Virtual Method can reside in abstract and non-abstract class.
• It is not necessary to override virtual method in derived but it can be.
• Virtual method must have body ....can be overridden by "override keyword".....

token_type is a parameter in Access Token generate call to Authorization server, which essentially represents how an access_token will be generated and presented for resource access calls. You provide token_type in the access token generation call to an authorization server.

If you choose Bearer (default on most implementation), an access_token is generated and sent back to you. Bearer can be simply understood as "give access to the bearer of this token." One valid token and no question asked. On the other hand, if you choose Mac and sign_type (default hmac-sha-1 on most implementation), the access token is generated and kept as secret in Key Manager as an attribute, and an encrypted secret is sent back as access_token.

Yes, you can use your own implementation of token_type, but that might not make much sense as developers will need to follow your process rather than standard implementations of OAuth.

Use a+ to open a file for reading, writing as well as create it if it doesn't exist.

a+ Opens a file for both appending and reading. The file pointer is at the end of the file if the file exists. The file opens in the append mode. If the file does not exist, it creates a new file for reading and writing. -Python file modes

with open('"File.txt', 'a+') as file:
    print(file.readlines())
    file.write("test")

Note: opening file in a with block makes sure that the file is properly closed at the block's end, even if an exception is raised on the way. It's equivalent to try-finally, but much shorter.

Maybe you should try

^[#;].*$

^ matches the beggining, $ the end.

The & makes the command run in the background.

From man bash:

If a command is terminated by the control operator &, the shell executes the command in the background in a subshell. The shell does not wait for the command to finish, and the return status is 0.

First of all thanks @Arvis for an eye opening explanation.

I prefer different solution to the accepted answer here for this problem. I don't like messing with overriding back behavior any more than absolutely necessary and when I've tried adding and removing fragments on my own without default back stack poping when back button is pressed I found my self in fragment hell :) If you .add f2 over f1 when you remove it f1 won't call any of callback methods like onResume, onStart etc. and that can be very unfortunate.

Anyhow this is how I do it:

Currently on display is only fragment f1.

f1 -> f2

Fragment2 f2 = new Fragment2();
this.getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content,f2).addToBackStack(null).commit();

nothing out of the ordinary here. Than in fragment f2 this code takes you to fragment f3.

f2 -> f3

Fragment3 f3 = new Fragment3();
getActivity().getSupportFragmentManager().popBackStack();
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

I'm not sure by reading docs if this should work, this poping transaction method is said to be asynchronous, and maybe a better way would be to call popBackStackImmediate(). But as far I can tell on my devices it's working flawlessly.

The said alternative would be:

final FragmentActivity activity = getActivity();
activity.getSupportFragmentManager().popBackStackImmediate();
activity.getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

Here there will actually be brief going back to f1 beofre moving on to f3, so a slight glitch there.

This is actually all you have to do, no need to override back stack behavior...

Just use this line:

PowerShell -Command "get-date"

Yes there still is no API for this (2.1). But it seemed like at WWDC a lot of people were already interested in the functionality (including myself) and the recommendation was to go to the below site and create a feature request for this. If there is enough of an interest, they might end up moving the ICal.framework to the public SDK.

https://developer.apple.com/bugreporter/

Use like this,

HTML:

<input type="text" disabled="disabled" class="inputDisabled" value="">

<div id="edit">edit</div>

JS:

 $('#edit').click(function(){ // click to
            $('.inputDisabled').attr('disabled',false); // removing disabled in this class
 });

O(n)

def find_pairs(L,sum):
    s = set(L)
    edgeCase = sum/2
    if L.count(edgeCase) ==2:
        print edgeCase, edgeCase
    s.remove(edgeCase)      
    for i in s:
        diff = sum-i
        if diff in s: 
            print i, diff


L = [2,45,7,3,5,1,8,9]
sum = 10          
find_pairs(L,sum)

Methodology: a + b = c, so instead of looking for (a,b) we look for a = c - b

That's because there was an error in your query. MySQli->query() will return false on error. Change it to something like::

$result = $this->database->query($query);
if (!$result) {
    throw new Exception("Database Error [{$this->database->errno}] {$this->database->error}");
}

That should throw an exception if there's an error...

HTML :

<div class="span4">
  <div class="panel panel-primary">
    <div class="panel-heading">jhdsahfjhdfhs</div>
    <div class="panel-body panel-height">fdoinfds sdofjohisdfj</div>
  </div>
</div>

CSS :

.panel-height {
  height: 100px; / change according to your requirement/
}

Dogbert's answer is good, but if your code might have to deal with negative numbers, Math.floor by itself may give unexpected results.

E.g. Math.floor(4.3) = 4, but Math.floor(-4.3) = -5

Use a helper function like this one instead to get consistent results:

truncateDecimals = function (number) {
    return Math[number < 0 ? 'ceil' : 'floor'](number);
};

// Applied to Dogbert's answer:
var a = 5.467;
var truncated = truncateDecimals(a * 100) / 100; // = 5.46

Here's a more convenient version of this function:

truncateDecimals = function (number, digits) {
    var multiplier = Math.pow(10, digits),
        adjustedNum = number * multiplier,
        truncatedNum = Math[adjustedNum < 0 ? 'ceil' : 'floor'](adjustedNum);

    return truncatedNum / multiplier;
};

// Usage:
var a = 5.467;
var truncated = truncateDecimals(a, 2); // = 5.46

// Negative digits:
var b = 4235.24;
var truncated = truncateDecimals(b, -2); // = 4200

If that isn't desired behaviour, insert a call to Math.abs on the first line:

var multiplier = Math.pow(10, Math.abs(digits)),

EDIT: shendz correctly points out that using this solution with a = 17.56 will incorrectly produce 17.55. For more about why this happens, read What Every Computer Scientist Should Know About Floating-Point Arithmetic. Unfortunately, writing a solution that eliminates all sources of floating-point error is pretty tricky with javascript. In another language you'd use integers or maybe a Decimal type, but with javascript...

This solution should be 100% accurate, but it will also be slower:

function truncateDecimals (num, digits) {
    var numS = num.toString(),
        decPos = numS.indexOf('.'),
        substrLength = decPos == -1 ? numS.length : 1 + decPos + digits,
        trimmedResult = numS.substr(0, substrLength),
        finalResult = isNaN(trimmedResult) ? 0 : trimmedResult;

    return parseFloat(finalResult);
}

For those who need speed but also want to avoid floating-point errors, try something like BigDecimal.js. You can find other javascript BigDecimal libraries in this SO question: "Is there a good Javascript BigDecimal library?" and here's a good blog post about math libraries for Javascript

Your only option is to somehow clone the object.

See this stackoverflow question on how you can achieve this.

For simple JSON objects, the simplest way would be:

var newObject = JSON.parse(JSON.stringify(oldObject));

if you use jQuery, you can use:

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

UPDATE 2017: I should mention, since this is a popular answer, that there are now better ways to achieve this using newer versions of javascript:

In ES6 or TypeScript (2.1+):

var shallowCopy = { ...oldObject };

var shallowCopyWithExtraProp = { ...oldObject, extraProp: "abc" };

Note that if extraProp is also a property on oldObject, its value will not be used because the extraProp : "abc" is specified later in the expression, which essentially overrides it. Of course, oldObject will not be modified.

This worked for me:

1. Close Android Studio.

2. Open the shell, and write:

   adb kill-server

   adb start-server

In the CSS all you have to do is put url(logical path to the image file)

ONE COLOR CASE - CSS only

Just to register my experience, where I wanted to set only the color of the selected option to a specific one.

I first tried to set by css only the color of the selected option with no success.

Then, after trying some combinations, this has worked for me with SCSS:

select {
      color: white; // color of the selected option

      option {
        color: black; // color of all the other options
      }
 }

Take a look at a working example with only CSS:

select {_x000D_
  color: yellow; // color of the selected option_x000D_
 }_x000D_
_x000D_
select option {_x000D_
  color: black; // color of all the other options_x000D_
}

<select id="mySelect">_x000D_
    <option value="apple" >Apple</option>_x000D_
    <option value="banana" >Banana</option>_x000D_
    <option value="grape" >Grape</option>_x000D_
</select>

For different colors, depending on the selected option, you'll have to deal with js.

If your objects only contain fields (no methods), this works:

$obj_merged = (object) array_merge((array) $obj1, (array) $obj2);

This actually also works when objects have methods. (tested with PHP 5.3 and 5.6)

Simply track your remote branches explicitly and a simple git pull will do just what you want:

git branch -f remote_branch_name origin/remote_branch_name
git checkout remote_branch_name

The latter is a local operation.

Or even more fitting in with the GitHub documentation on forking:

git branch -f new_local_branch_name upstream/remote_branch_name

Complete stretching (horizontal/vertical)

The accepted answer is great. Just want to point out some things for others coming here. Margins are not necessary in these cases. If you want a centered layout with a specific "Margin", you can add them to the right and left, like so:

.stretched {
  position: absolute;
  right: 50px;  top: 0;  bottom: 0; left: 50px;
  margin: auto;
}

This is extremely useful.

Centering div (vertical/horizontally)

As a bonus, absolute centering which can be used to get extremely simple centering:

.centered {
  height: 100px;  width: 100px;  
  right: 0;  top: 0;  bottom: 0; left: 0;
  margin: auto;
  position: absolute;
}

To do this for oracle sql, the syntax would be:

,SUBSTR(col,INSTR(col,'-',1,2)+1) AS new_field

for this example, I look for the second '-' and take the substring to the end

From the documentation:

The load factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased

It really depends on your particular requirements, there's no "rule of thumb" for specifying an initial load factor.

In Python 2.x this is not guaranteed as it is possible for True and False to be reassigned. However, even if this happens, boolean True and boolean False are still properly returned for comparisons.

In Python 3.x True and False are keywords and will always be equal to 1 and 0.

Under normal circumstances in Python 2, and always in Python 3:

False object is of type bool which is a subclass of int:

object
   |
 int
   |
 bool

It is the only reason why in your example, ['zero', 'one'][False] does work. It would not work with an object which is not a subclass of integer, because list indexing only works with integers, or objects that define a __index__ method (thanks mark-dickinson).

Edit:

It is true of the current python version, and of that of Python 3. The docs for python 2 and the docs for Python 3 both say:

There are two types of integers: [...] Integers (int) [...] Booleans (bool)

and in the boolean subsection:

Booleans: These represent the truth values False and True [...] Boolean values behave like the values 0 and 1, respectively, in almost all contexts, the exception being that when converted to a string, the strings "False" or "True" are returned, respectively.

There is also, for Python 2:

In numeric contexts (for example when used as the argument to an arithmetic operator), they [False and True] behave like the integers 0 and 1, respectively.

So booleans are explicitly considered as integers in Python 2 and 3.

So you're safe until Python 4 comes along. ;-)

You don't need all that code. All you need are the following lines:

Here is an elegant solution.

There is hidden property for each input element on the form that you can use to determine whether or not the value was changed. Each type of input has it's own property name. For example

• for text/textarea it's defaultValue
• for select it's defaultSelect
• for checkbox/radio it's defaultChecked

Here is the example.

function bindFormChange($form) {

  function touchButtons() {
    var
      changed_objects = [],
      $observable_buttons = $form.find('input[type="submit"], button[type="submit"], button[data-object="reset-form"]');

    changed_objects = $('input:text, input:checkbox, input:radio, textarea, select', $form).map(function () {
      var
        $input = $(this),
        changed = false;

      if ($input.is('input:text') || $input.is('textarea') ) {
        changed = (($input).prop('defaultValue') != $input.val());
      }
      if (!changed && $input.is('select') ) {
        changed = !$('option:selected', $input).prop('defaultSelected');
      }
      if (!changed && $input.is('input:checkbox') || $input.is('input:radio') ) {
        changed = (($input).prop('defaultChecked') != $input.is(':checked'));
      }
      if (changed) {
        return $input.attr('id');
      }

    }).toArray();

    if (changed_objects.length) {
      $observable_buttons.removeAttr('disabled')   
    } else {
      $observable_buttons.attr('disabled', 'disabled');
    }
  };
  touchButtons();

  $('input, textarea, select', $form).each(function () {
    var $input = $(this);

    $input.on('keyup change', function () {
      touchButtons();
    });
  });

};

Now just loop thru the forms on the page and you should see submit buttons disabled by default and they will be activated ONLY if you indeed will change some input value on the form.

$('form').each(function () {
    bindFormChange($(this));
});

Yes, H2 supports executing SQL statements when connecting. You could run a script, or just a statement or two:

String url = "jdbc:h2:mem:test;" + 
             "INIT=CREATE SCHEMA IF NOT EXISTS TEST"
String url = "jdbc:h2:mem:test;" + 
             "INIT=CREATE SCHEMA IF NOT EXISTS TEST\\;" + 
                  "SET SCHEMA TEST";
String url = "jdbc:h2:mem;" + 
             "INIT=RUNSCRIPT FROM '~/create.sql'\\;" + 
                  "RUNSCRIPT FROM '~/populate.sql'";

Please note the double backslash (\\) is only required within Java. The backslash(es) before ; within the INIT is required.

CURL-less method with PHP5:

$url = 'http://server.com/path';
$data = array('key1' => 'value1', 'key2' => 'value2');

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data)
    )
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }

var_dump($result);

See the PHP manual for more information on the method and how to add headers, for example:

• stream_context_create: http://php.net/manual/en/function.stream-context-create.php

Simple function for splitting a vector by simply using indexes - no need to over complicate this

vsplit <- function(v, n) {
    l = length(v)
    r = l/n
    return(lapply(1:n, function(i) {
        s = max(1, round(r*(i-1))+1)
        e = min(l, round(r*i))
        return(v[s:e])
    }))
}

I had the same problem. Firefox showed me this error but in chrome everything was OK. then after a google search, i used google cdn for jquery in index.html instead of loading local js file and the problem solved.

In Android the "work queue processor" pattern is commonly used to offload tasks from an application's main thread.

Example: The design of the IntentService class.

The IntentService receives the Intents, launch a worker thread, and stops the service as appropriate.All requests are handled on a single worker thread.

If you have a basic form, just make the input type of email: <input type="email" required>

This will work for browsers that use HTML5 attributes and then you do not even need JS. Just using email validation even with some of the scripts above will not do much since:

[email protected] [email protected] [email protected]

etc... Will all validate as "real" emails. So you would be better off ensuring that the user has to enter their email address twice to make sure that they put the same one in. But to guarantee that the email address is real would be very difficult but very interesting to see if there was a way. But if you are just making sure that it is an email, stick to the HTML5 input.

FIDDLE EXAMPLE

This works in FireFox and Chrome. It may not work in Internet Explorer... But internet explorer sucks. So then there's that...

Short answer: I think tgbaggio is right. You hit HDFS throughput limits on your executors.

I think the answer here may be a little simpler than some of the recommendations here.

The clue for me is in the cluster network graph. For run 1 the utilization is steady at ~50 M bytes/s. For run 3 the steady utilization is doubled, around 100 M bytes/s.

From the cloudera blog post shared by DzOrd, you can see this important quote:

I’ve noticed that the HDFS client has trouble with tons of concurrent threads. A rough guess is that at most five tasks per executor can achieve full write throughput, so it’s good to keep the number of cores per executor below that number.

So, let's do a few calculations see what performance we expect if that is true.

Run 1: 19 GB, 7 cores, 3 executors

• 3 executors x 7 threads = 21 threads
• with 7 cores per executor, we expect limited IO to HDFS (maxes out at ~5 cores)
• effective throughput ~= 3 executors x 5 threads = 15 threads

Run 3: 4 GB, 2 cores, 12 executors

• 2 executors x 12 threads = 24 threads
• 2 cores per executor, so hdfs throughput is ok
• effective throughput ~= 12 executors x 2 threads = 24 threads

If the job is 100% limited by concurrency (the number of threads). We would expect runtime to be perfectly inversely correlated with the number of threads.

ratio_num_threads = nthread_job1 / nthread_job3 = 15/24 = 0.625
inv_ratio_runtime = 1/(duration_job1 / duration_job3) = 1/(50/31) = 31/50 = 0.62

So ratio_num_threads ~= inv_ratio_runtime, and it looks like we are network limited.

This same effect explains the difference between Run 1 and Run 2.

Run 2: 19 GB, 4 cores, 3 executors

• 3 executors x 4 threads = 12 threads
• with 4 cores per executor, ok IO to HDFS
• effective throughput ~= 3 executors x 4 threads = 12 threads

Comparing the number of effective threads and the runtime:

ratio_num_threads = nthread_job2 / nthread_job1 = 12/15 = 0.8
inv_ratio_runtime = 1/(duration_job2 / duration_job1) = 1/(55/50) = 50/55 = 0.91

It's not as perfect as the last comparison, but we still see a similar drop in performance when we lose threads.

Now for the last bit: why is it the case that we get better performance with more threads, esp. more threads than the number of CPUs?

A good explanation of the difference between parallelism (what we get by dividing up data onto multiple CPUs) and concurrency (what we get when we use multiple threads to do work on a single CPU) is provided in this great post by Rob Pike: Concurrency is not parallelism.

The short explanation is that if a Spark job is interacting with a file system or network the CPU spends a lot of time waiting on communication with those interfaces and not spending a lot of time actually "doing work". By giving those CPUs more than 1 task to work on at a time, they are spending less time waiting and more time working, and you see better performance.

Use the value attribute of the button element to pass the id, as

<button onClick={this.handleRemove} value={id}>Remove</button>

and then in handleRemove, read the value from event as:

handleRemove(event) {
...
 remove(event.target.value);
...
}

This way you avoid creating a new function (when compared to using an arrow function) every time this component is re-rendered.

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

I had a Visual Studio behavior where the typing was slow for my HTML files. Previously when I installed, I guessed that because my HTML files were generic HTML that the need to install any web development tools from the workload component of the installer was unnecessary. I went back and installed this bit and Visual Studio behavior became as I expected it.

To me, this is the most "natural" way to structure such data in JSON, provided that all of the keys are strings.

{
    "keyvaluelist": {
        "slide0001.html": "Looking Ahead",
        "slide0008.html": "Forecast",
        "slide0021.html": "Summary"
    },
    "otherdata": {
        "one": "1",
        "two": "2",
        "three": "3"
    },
    "anotherthing": "thing1",
    "onelastthing": "thing2"
}

I read this as

a JSON object with four elements
    element 1 is a map of key/value pairs named "keyvaluelist",
    element 2 is a map of key/value pairs named "otherdata",
    element 3 is a string named "anotherthing",
    element 4 is a string named "onelastthing"

The first element or second element could alternatively be described as objects themselves, of course, with three elements each.

It worked for me after I tried it.

This also happens if you're missing an empty public constructor for the Entity (could be for JSON, XML etc)..

You might get even better results if you try:

console.log(JSON.stringify(obj, null, 4));

I also did not know how to do this until I thought of using PHP array's. And I am pretty sure this is the simplest way of generating a random string or number with array's. The code:

function randstr ($len=10, $abc="aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ0123456789") {
    $letters = str_split($abc);
    $str = "";
    for ($i=0; $i<=$len; $i++) {
        $str .= $letters[rand(0, count($letters)-1)];
    };
    return $str;
};

You can use this function like this

randstr(20)     // returns a random 20 letter string
                // Or like this
randstr(5, abc) // returns a random 5 letter string using the letters "abc"

Header Row cells sometimes will not work. This will just return the column Index. It will help in a lot of different ways. I know this is not the answer he is requesting. But this will help for a lot people.

public static int GetColumnIndexByHeaderText(GridView gridView, string columnName)
    {      
        for (int i = 0; i < gridView.Columns.Count ; i++)
        {
            if (gridView.Columns[i].HeaderText.ToUpper() == columnName.ToUpper() )
            {
                return i;
            }
        }     
        return -1;
    }

You do realize that format has nothing to do with how SQL Server stores datetime, right?

You can use set dateformat for each session. There is no setting for database only.

If you use parameters for data insert or update or where filtering you won't have any problems with that.

Please do not copy from the clipboard . Just copy the url from your browser's location / Address bar .

This is my solution to create a fullscreen div, using pure css. It displays a full screen div that is persistent on scrolling. And if the page content fits on the screen, the page won't show a scroll-bar.

Another case to use a multi line function would be to circumvent sql server from pushing down the where clause.

For example, I have a table with a table names and some table names are formatted like C05_2019 and C12_2018 and and all tables formatted that way have the same schema. I wanted to merge all that data into one table and parse out 05 and 12 to a CompNo column and 2018,2019 into a year column. However, there are other tables like ACA_StupidTable which I cannot extract CompNo and CompYr and would get a conversion error if I tried. So, my query was in two part, an inner query that returned only tables formatted like 'C_______' then the outer query did a sub-string and int conversion. ie Cast(Substring(2, 2) as int) as CompNo. All looks good except that sql server decided to put my Cast function before the results were filtered and so I get a mind scrambling conversion error. A multi statement table function may prevent that from happening, since it is basically a "new" table.

Spring Boot already has support for profile based properties.

Simply add an application-[profile].properties file and specify the profiles to use using the spring.profiles.active property.

-Dspring.profiles.active=local

This will load the application.properties and the application-local.properties with the latter overriding properties from the first.

Check out this plugin that does exacly that - jquery.initialize

It works exacly like .each function, the difference is it takes selector you've entered and watch for new items added in future matching this selector and initialize them

Initialize looks like this

$(".some-element").initialize( function(){
    $(this).css("color", "blue");
});

But now if new element matching .some-element selector will appear on page, it will be instanty initialized.

The way new item is added is not important, you dont need to care about any callbacks etc.

So if you'd add new element like:

$("<div/>").addClass('some-element').appendTo("body"); //new element will have blue color!

it will be instantly initialized.

Plugin is based on MutationObserver

Maybe something like this:

connected = False

while not connected:
    try:
        try_connect()
        connected = True
    except ...:
        pass

You can also define the pointcut as

public pointcut publicMethodInsideAClassMarkedWithAtMonitor() : execution(public * (@Monitor *).*(..));

If the string is very large then copy will affect performance and two copies of the large string will use more memory.

personaly, i'm using exceptions to handle validation. it requires following steps:

1. in your data binding expression, you need to add "ValidatesOnException=True"
2. in you data object you are binding to, you need to add DependencyPropertyChanged handler where you check if new value fulfills your conditions - if not - you restore to the object old value (if you need to) and you throw exception.
3. in your control template you use for displaying invalid value in the control, you can access Error collection and display exception message.

the trick here, is to bind only to objects which derive from DependencyObject. simple implementation of INotifyPropertyChanged wouldn't work - there is a bug in the framework, which prevents you from accessing error collection.

Using ES6 syntax in React does not bind this to user-defined functions however it will bind this to the component lifecycle methods.

So the function that you declared will not have the same context as the class and trying to access this will not give you what you are expecting.

For getting the context of class you have to bind the context of class to the function or use arrow functions.

Method 1 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.onMove = this.onMove.bind(this);
        this.testVarible= "this is a test";
    }

    onMove() {
        console.log(this.testVarible);
    }
}

Method 2 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.testVarible= "this is a test";
    }

    onMove = () => {
        console.log(this.testVarible);
    }
}

Method 2 is my preferred way but you are free to choose your own.

Update: You can also create the properties on class without constructor:

class MyContainer extends Component {

    testVarible= "this is a test";

    onMove = () => {
        console.log(this.testVarible);
    }
}

Note If you want to update the view as well, you should use state and setState method when you set or change the value.

Example:

class MyContainer extends Component {

    state = { testVarible: "this is a test" };

    onMove = () => {
        console.log(this.state.testVarible);
        this.setState({ testVarible: "new value" });
    }
}

public class Book
{
    public int number;
    public String title;
    public String language;
    public int price;

    // Add constructor, get, set, as needed.
}

then declare your array as:

Book[] books = new Book[3];

EDIT: In response to O.P.'s confusion, Book should be an object, not an array. Each book should be created on it's own (via a properly designed constructor) and then added to the array. In fact, I wouldn't use an array, but an ArrayList. In other words, you are trying to force data into containers that aren't suitable for the task at hand.

I would venture that 50% of programming is choosing the right data structure for your data. Algorithms naturally follow if there is a good choice of structure.

When properly done, you get your UI class to look like: Edit: Generics added to the following code snippet.

...
ArrayList<Book> myLibrary = new ArrayList<Book>();
myLibrary.add(new Book(1, "Thinking In Java", "English", 4999));
myLibrary.add(new Book(2, "Hacking for Fun and Profit", "English", 1099);

etc.

now you can use the Collections interface and do something like:

int total = 0;
for (Book b : myLibrary)
{
   total += b.price;
   System.out.println(b); // Assuming a valid toString in the Book class
}
System.out.println("The total value of your library is " + total);

First method

For Windows 7 and above users, Windows PowerShell give you this option. Users with windows version less than 7 can download PowerShell online and install it.

Steps:

1. type PowerShell in search area and click on "Windows PowerShell"

2. If you have a .bat (batch) file go to step 3 OR copy your commands to a file and save it with .bat extension (e.g. file.bat)

3. run the .bat file with following command

   PS (location)> <path to bat file>/file.bat | Tee-Object -file log.txt

This will generate a log.txt file with all command prompt output in it. Advantage is that you can also the output on command prompt.

Second method

You can use file redirection (>, >>) as suggest by Bali C above.

I will recommend first method if you have lots of commands to run or a script to run. I will recommend last method if there is only few commands to run.

Rules are used to add additional functionality which applies to all tests within a test class, but in a more generic way.

For instance, ExternalResource executes code before and after a test method, without having to use @Before and @After. Using an ExternalResource rather than @Before and @After gives opportunities for better code reuse; the same rule can be used from two different test classes.

The design was based upon: Interceptors in JUnit

For more information see JUnit wiki : Rules.

Please run this in your terminal:

$ vagrant box list

You will see something like laravel/homestead(virtualbox,x.x.x)

Next locate your Vagrantfile and locate the line that says

config.vm.box = "box"

replace box with the box name when you run vagrant box list.

Here is another simple method using awk:

# cat > file.txt
a
b
c

# cat file.txt | awk '{ printf("%s ", $0) }'
a b c

Also, if your file has columns, this gives an easy way to concatenate only certain columns:

# cat > cols.txt
a b c
d e f

# cat cols.txt | awk '{ printf("%s ", $2) }'
b e

If you want to set the same value on a collection of rows, you can use the update() method combined with any query term to update all rows in one query:

some_list = ModelClass.objects.filter(some condition).values('id')
ModelClass.objects.filter(pk__in=some_list).update(foo=bar)

If you want to update a collection of rows with different values depending on some condition, you can in best case batch the updates according to values. Let's say you have 1000 rows where you want to set a column to one of X values, then you could prepare the batches beforehand and then only run X update-queries (each essentially having the form of the first example above) + the initial SELECT-query.

If every row requires a unique value there is no way to avoid one query per update. Perhaps look into other architectures like CQRS/Event sourcing if you need performance in this latter case.

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

You could try this(this uses a constructor, but I'm sure you can change it around a bit):

function Obj() {
    this.subObj = {
        // code
    }
    this.subObj.parent = this;
}

You need to do two things, one is to set the height to 100% which you already did. Second is set the position to absolute. That should do the trick.

html,
body {
  height: 100%;
  min-height: 100%;
  position: absolute;
}

The vimrc file in Ubuntu (12.04 (Precise Pangolin)): I tried :scriptnames in Vim, and it shows both /usr/share/vim/vimrc and ~/.vimrc.

But I had manually created ~/.vimrc.

Use the Linux split command:

split -l 20 file.txt new    

Split the file "file.txt" into files beginning with the name "new" each containing 20 lines of text each.

Type man split at the Unix prompt for more information. However you will have to first remove the header from file.txt (using the tail command, for example) and then add it back on to each of the split files.

make sure the deployment target version in setting is lower or equal than the iphone version

if the deployment target is 7.1 but the iphone is 7.0.3

you will see that error message

A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.

In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)

This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.

Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The implementation depends on the programming language that you chose.

If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.

You need to use IFS to stop space as element delimiter.

FILES=("2011-09-04 21.43.02.jpg"
       "2011-09-05 10.23.14.jpg"
       "2011-09-09 12.31.16.jpg"
       "2011-09-11 08.43.12.jpg")
IFS=""
for jpg in ${FILES[*]}
do
    echo "${jpg}"
done

If you want to separate on basis of . then just do IFS="." Hope it helps you:)

In terms of Speed, Parcelable > Serializable. But, Custom Serializable is exception. It is almost in range of Parcelable or even more faster.

Reference : https://www.geeksforgeeks.org/customized-serialization-and-deserialization-in-java/

Example :

Custom Class to be serialized

class MySerialized implements Serializable { 

    String deviceAddress = "MyAndroid-04"; 

    transient String token = "AABCDS"; // sensitive information which I do not want to serialize

    private void writeObject(ObjectOutputStream oos) throws Exception {
        oos.defaultWriteObject();
        oos.writeObject("111111" + token); // Encrypted token to be serialized
    }

    private void readObject(ObjectInputStream ois) throws Exception {
        ois.defaultReadObject(); 
        token = ((String) ois.readObject()).subString(6);  // Decrypting token
    }

}

I created an example spreadsheet here of how to do this with simple Excel formulae, and without use of macros (you will need to make your own adjustments for getting rid of the first row, but this should be easy once you figure out how my example spreadsheet works):

https://docs.google.com/a/umich.edu/spreadsheet/ccc?key=0AuSyDFZlcRtHdGJOSnFwREotRzFfM28tWElpZ1FaR2c#gid=0

there are a lot of ways to check if an int value is odd or even. I'll show you the two main ways:

number = 5

def best_way(number):
    if number%2==0:
        print "even"
    else:
        print "odd"

def binary_way(number):
    if str(bin(number))[len(bin(number))-1]=='0':
        print "even"
    else:
        print "odd"
best_way(number)
binary_way(number)

hope it helps

The answer to your question is actually two-fold. First of all you need to specify what you intend to do with the rendered HTML: save it to a new PDF file, or use it within another rendering context (i.e. add it to some other document you are generating).

The former is relatively easily accomplished using the Flying Saucer framework, which can be found here: https://github.com/flyingsaucerproject/flyingsaucer

The latter is actually a much more comprehensive problem that needs to be categorized further. Using iText you won't be able to (trivially, at least) combine iText elements (i.e. Paragraph, Phrase, Chunk and so on) with the generated HTML. You can hack your way out of this by using the ContentByte's addTemplate method and generating the HTML to this template.

If you on the other hand want to stamp the generated HTML with something like watermarks, dates or the like, you can do this using iText.

So bottom line: You can't trivially integrate the rendered HTML in other pdf generating contexts, but you can render HTML directly to a blank PDF document.

String.prototype.padZero= function(len, c){
    var s= this, c= c || '0';
    while(s.length< len) s= c+ s;
    return s;
}

dispite the name, you can left-pad with any character, including a space. I never had a use for right side padding, but that would be easy enough.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

I came across this for css

As of middle 2016, there is no official way to restrict viewable area. Most of ad-hoc solutions to restrict the bounds have a flaw though, because they don't restrict the bounds exactly to fit the map view, they only restrict it if the center of the map is out of the specified bounds. If you want to restrict the bounds to overlaying image like me, this can result in a behavior like illustrated below, where the underlaying map is visible under our image overlay:

To tackle this issue, I have created a library, which successfully restrict the bounds so you cannot pan out of the overlay.

However, as other existing solutions, it has a "vibrating" issue. When the user pans the map aggressively enough, after they release the left mouse button, the map still continues panning by itself, gradually slowing. I always return the map back to the bounds, but that results in kind of vibrating. This panning effect cannot be stopped with any means provided by the Js API at the moment. It seems that until google adds support for something like map.stopPanningAnimation() we won't be able to create a smooth experience.

Example using the mentioned library, the smoothest strict bounds experience I was able to get:

function initialise(){_x000D_
  _x000D_
  var myOptions = {_x000D_
     zoom: 5,_x000D_
     center: new google.maps.LatLng(0,0),_x000D_
     mapTypeId: google.maps.MapTypeId.ROADMAP,_x000D_
  };_x000D_
  var map = new google.maps.Map(document.getElementById('map'), myOptions);_x000D_
  _x000D_
  addStrictBoundsImage(map);_x000D_
}_x000D_
_x000D_
function addStrictBoundsImage(map){_x000D_
 var bounds = new google.maps.LatLngBounds(_x000D_
  new google.maps.LatLng(62.281819, -150.287132),_x000D_
  new google.maps.LatLng(62.400471, -150.005608));_x000D_
_x000D_
 var image_src = 'https://developers.google.com/maps/documentation/' +_x000D_
  'javascript/examples/full/images/talkeetna.png';_x000D_
_x000D_
 var strict_bounds_image = new StrictBoundsImage(bounds, image_src, map);_x000D_
}

<script type="text/javascript" src="http://www.google.com/jsapi"></script>_x000D_
      <script type="text/javascript">_x000D_
        google.load("maps", "3",{other_params:"sensor=false"});_x000D_
      </script>_x000D_
<body style="margin:0px; padding:0px;" onload="initialise()">_x000D_
  <div id="map" style="height:400px; width:500px;"></div>_x000D_
     <script  type="text/javascript"src="https://raw.githubusercontent.com/matej-pavla/StrictBoundsImage/master/StrictBoundsImage.js"></script>_x000D_
</body>

The library is also able to calculate the minimum zoom restriction automatically. It then restricts the zoom level using minZoom map's attribute.

Hopefully this helps someone who wants a solution which fully respect the given boundaries and doesn't want to allow panning out of them.

You can use Web SQL API which is an ordinary SQLite database in your browser and you can open/modify it like any other SQLite databases for example with Lita.

Chrome locates databases automatically according to domain names or extension id. A few months ago I posted on my blog short article on how to delete Chrome's database because when you're testing some functionality it's quite useful.

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;
}

Use the excellent jQuery Sparkle plugin. The plugin gives you the option to detect first and last click. You can use it to differentiate between click and dblclick by detecting if another click was followed by the first click.

Check it out at http://balupton.com/sandbox/jquery-sparkle/demo/

The other thing you can do is use HSTS by returning the "Strict-Transport-Security" header to the browser. The browser has to support this (and at present, it's primarily Chrome and Firefox that do), but it means that once set, the browser won't make requests to the site over HTTP and will instead translate them to HTTPS requests before issuing them. Try this in combination with a redirect from HTTP:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
  switch (Request.Url.Scheme)
  {
    case "https":
      Response.AddHeader("Strict-Transport-Security", "max-age=300");
      break;
    case "http":
      var path = "https://" + Request.Url.Host + Request.Url.PathAndQuery;
      Response.Status = "301 Moved Permanently";
      Response.AddHeader("Location", path);
      break;
  }
}

Browsers that aren't HSTS aware will just ignore the header but will still get caught by the switch statement and sent over to HTTPS.

You could try this SendKeys jQuery plugin:

http://bililite.com/blog/2011/01/23/improved-sendkeys/

$(element).sendkeys(string) inserts string at the insertion point in an input, textarea or other element with contenteditable=true. If the insertion point is not currently in the element, it remembers where the insertion point was when sendkeys was last called (if the insertion point was never in the element, it appends to the end).

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.

If you want to import a specific function or class from a module, you can do this:

import importlib
import sys
importlib.reload(sys.modules['my_module'])
from my_module import my_function

You can try with this:

WITH CTE_A As (SELECT COUNT(*) as articleNumber,A.UserID  as UserID FROM Articles A
           Inner Join Users U
           on  A.userId = U.userId 
           Group By A.userId , U.userId   ),

B as (Select us.registrationDate,

      CASE
         WHEN CTE_A.articleNumber < 2 THEN 'Ama'
         WHEN CTE_A.articleNumber < 5 THEN 'SemiAma' 
         WHEN CTE_A.articleNumber < 7 THEN 'Good'  
         WHEN CTE_A.articleNumber < 9 THEN 'Better' 
         WHEN CTE_A.articleNumber < 12 THEN 'Best'
         ELSE 'Outstanding'
         END as Ranking,
         us.hobbies, etc...
         FROM USERS Us Inner Join CTE_A 
         on CTE_A.UserID=us.UserID)

Select * from B

The ActiveState recipe quoted verbatim in two answers is over-engineered. It can be boiled down to this:

def _find_getch():
    try:
        import termios
    except ImportError:
        # Non-POSIX. Return msvcrt's (Windows') getch.
        import msvcrt
        return msvcrt.getch

    # POSIX system. Create and return a getch that manipulates the tty.
    import sys, tty
    def _getch():
        fd = sys.stdin.fileno()
        old_settings = termios.tcgetattr(fd)
        try:
            tty.setraw(fd)
            ch = sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
        return ch

    return _getch

getch = _find_getch()
