You are using the correct API, but is the "marker" variable visible to the entire script. I don't see this marker variable declared globally.

If you are using Guava, you can use Files.move(from, to)

For example, if I wanted to move all .txt files from one location to another ( on a Windows OS for instance ) I would do it something like this:

import shutil
import os,glob

inpath = 'R:/demo/in' 
outpath = 'R:/demo/out'

os.chdir(inpath)
for file in glob.glob("*.txt"):

    shutil.move(inpath+'/'+file,outpath)

Try this :-

  boolean success = file.renameTo(new File(Destdir, file.getName()));

Use file this code

function move_file($path,$to){
   if(copy($path, $to)){
      unlink($path);
      return true;
   } else {
     return false;
   }
 }

You can just delete that directory that you cloned the repo into, and re-clone it wherever you'd like.

/q isn't a valid parameter. /y: Suppresses prompting to confirm overwriting

Also ..\txt means directory txt under the parent directory, not the root directory. The root directory would be: \ And please mention the error you get

Try:

move files\*.txt \ 

Edit: Try:

move \files\*.txt \ 

Edit 2:

move C:\files\*.txt C:\txt

Previous answers seem to be outdated.

Java's File.renameTo() is probably the easiest solution for API 7, and seems to work fine. Be carefull IT DOES NOT THROW EXCEPTIONS, but returns true/false!!!

Note that there seem to be problems with it in previous versions (same as NIO).

If you need to use a previous version, check here.

Here's an example for API7:

File f1= new File("C:\\Users\\.....\\foo");
File f2= new File("C:\\Users\\......\\foo.old");
System.err.println("Result of move:"+f1.renameTo(f2));

Alternatively:

System.err.println("Move:" +f1.toURI() +"--->>>>"+f2.toURI());
Path b1=Files.move(f1.toPath(),  f2.toPath(), StandardCopyOption.ATOMIC_MOVE ,StandardCopyOption.REPLACE_EXISTING ););
System.err.println("Move: RETURNS:"+b1);

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

If you also need to overwrite files with read only flag use this:

def copyDirTree(root_src_dir,root_dst_dir):
"""
Copy directory tree. Overwrites also read only files.
:param root_src_dir: source directory
:param root_dst_dir:  destination directory
"""
for src_dir, dirs, files in os.walk(root_src_dir):
    dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1)
    if not os.path.exists(dst_dir):
        os.makedirs(dst_dir)
    for file_ in files:
        src_file = os.path.join(src_dir, file_)
        dst_file = os.path.join(dst_dir, file_)
        if os.path.exists(dst_file):
            try:
                os.remove(dst_file)
            except PermissionError as exc:
                os.chmod(dst_file, stat.S_IWUSR)
                os.remove(dst_file)

        shutil.copy(src_file, dst_dir)

You can use the df.reindex() function in pandas. df is

                      Net  Upper   Lower  Mid  Zsore
Answer option

Once a day            0%  0.32%  -0.19%    3     45
Several times a week  2%  2.45%   1.10%    4     78
Once a week           1%  1.63%  -0.40%    6     65

define an list of column names

cols = df.columns.tolist()
cols
Out[13]: ['Net', 'Upper', 'Lower', 'Mid', 'Zsore']

move the column name to wherever you want

cols.insert(0, cols.pop(cols.index('Mid')))
cols
Out[16]: ['Mid', 'Net', 'Upper', 'Lower', 'Zsore']

then use df.reindex() function to reorder

df = df.reindex(columns= cols)

out put is: df

Try this to move your table (tbl1) to tablespace (tblspc2).

alter table tb11 move tablespace tblspc2;

This code can distinguish between click and movement (drag, scroll). In onTouchEvent set a flag isOnClick, and initial X, Y coordinates on ACTION_DOWN. Clear the flag on ACTION_MOVE (minding that unintentional movement is often detected which can be solved with a THRESHOLD const).

private float mDownX;
private float mDownY;
private final float SCROLL_THRESHOLD = 10;
private boolean isOnClick;

@Override
public boolean onTouchEvent(MotionEvent ev) {
    switch (ev.getAction() & MotionEvent.ACTION_MASK) {
        case MotionEvent.ACTION_DOWN:
            mDownX = ev.getX();
            mDownY = ev.getY();
            isOnClick = true;
            break;
        case MotionEvent.ACTION_CANCEL:
        case MotionEvent.ACTION_UP:
            if (isOnClick) {
                Log.i(LOG_TAG, "onClick ");
                //TODO onClick code
            }
            break;
        case MotionEvent.ACTION_MOVE:
            if (isOnClick && (Math.abs(mDownX - ev.getX()) > SCROLL_THRESHOLD || Math.abs(mDownY - ev.getY()) > SCROLL_THRESHOLD)) {
                Log.i(LOG_TAG, "movement detected");
                isOnClick = false;
            }
            break;
        default:
            break;
    }
    return true;
}

For LongPress as suggested above, GestureDetector is the way to go. Check this Q&A:

Detecting a long press with Android

Create a file called MoveFiles.bat with the syntax

move c:\Sourcefoldernam\*.* e:\destinationFolder

then schedule a task to run that MoveFiles.bat every 10 hours.

As bash does not have a built-in value in array operator and the =~ operator or the [[ "${array[@]" == *"${item}"* ]] notation keep confusing me, I usually combine grep with a here-string:

colors=('black' 'blue' 'light green')
if grep -q 'black' <<< "${colors[@]}"
then
    echo 'match'
fi

Beware however that this suffers from the same false positives issue as many of the other answers that occurs when the item to search for is fully contained, but is not equal to another item:

if grep -q 'green' <<< "${colors[@]}"
then
    echo 'should not match, but does'
fi

If that is an issue for your use case, you probably won't get around looping over the array:

for color in "${colors[@]}"
do
    if [ "${color}" = 'green' ]
    then
        echo "should not match and won't"
        break
    fi
done

for color in "${colors[@]}"
do
    if [ "${color}" = 'light green' ]
    then
        echo 'match'
        break
    fi
done

Swift 3

In Swift 3 there is addingPercentEncoding

let originalString = "test/test"
let escapedString = originalString.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
print(escapedString!)

Output:

test%2Ftest

Swift 1

In iOS 7 and above there is stringByAddingPercentEncodingWithAllowedCharacters

var originalString = "test/test"
var escapedString = originalString.stringByAddingPercentEncodingWithAllowedCharacters(.URLHostAllowedCharacterSet())
println("escapedString: \(escapedString)")

Output:

test%2Ftest

The following are useful (inverted) character sets:

URLFragmentAllowedCharacterSet  "#%<>[\]^`{|}
URLHostAllowedCharacterSet      "#%/<>?@\^`{|}
URLPasswordAllowedCharacterSet  "#%/:<>?@[\]^`{|}
URLPathAllowedCharacterSet      "#%;<>?[\]^`{|}
URLQueryAllowedCharacterSet     "#%<>[\]^`{|}
URLUserAllowedCharacterSet      "#%/:<>?@[\]^`

If you want a different set of characters to be escaped create a set:
Example with added "=" character:

var originalString = "test/test=42"
var customAllowedSet =  NSCharacterSet(charactersInString:"=\"#%/<>?@\\^`{|}").invertedSet
var escapedString = originalString.stringByAddingPercentEncodingWithAllowedCharacters(customAllowedSet)
println("escapedString: \(escapedString)")

Output:

test%2Ftest%3D42

Example to verify ascii characters not in the set:

func printCharactersInSet(set: NSCharacterSet) {
    var characters = ""
    let iSet = set.invertedSet
    for i: UInt32 in 32..<127 {
        let c = Character(UnicodeScalar(i))
        if iSet.longCharacterIsMember(i) {
            characters = characters + String(c)
        }
    }
    print("characters not in set: \'\(characters)\'")
}

This one would also work:

google.maps.event.addListener(marker, 'click', function() {
                if(!marker.open){
                    infowindow.open(map,marker);
                    marker.open = true;
                }
                else{
                    infowindow.close();
                    marker.open = false;
                }
            });

Which will open an infoWindow when clicked on it, close it when clicked on it if it was opened.

Also having seen Logan's solution, these 2 can be combined into this:

google.maps.event.addListener(marker, 'click', function() {
                if(!marker.open){
                    infowindow.open(map,marker);
                    marker.open = true;
                }
                else{
                    infowindow.close();
                    marker.open = false;
                }
                google.maps.event.addListener(map, 'click', function() {
                    infowindow.close();
                    marker.open = false;
                });
            });

Which will open an infoWindow when clicked on it, close it when clicked on it and it was opened, and close it if it's clicked anywhere on the map and the infoWindows was opened.

It depends on the output of file which I am not sure is standardized on all systems. Some JPEGs don't report the image size

import subprocess, re
image_size = list(map(int, re.findall('(\d+)x(\d+)', subprocess.getoutput("file" + filename))[-1]))

use from

You can name the dataframe with the following, and then call the name wherever you like:

import pandas as pd
df = pd.DataFrame( data=np.ones([4,4]) )
df.name = 'Ones'

print df.name
>>>
Ones

Hope that helps.

      console.log('my width :::', myWidth)
   })
  },[window])

  return (

   </>
  )
}

It's undefined behavior as far as I know. Run a larger program with that and it will crash somewhere along the way. Bounds checking is not a part of raw arrays (or even std::vector).

Use std::vector with std::vector::iterator's instead so you don't have to worry about it.

Edit:

Just for fun, run this and see how long until you crash:

int main()
{
   int array[1];

   for (int i = 0; i != 100000; i++)
   {
       array[i] = i;
   }

   return 0; //will be lucky to ever reach this
}

Edit2:

Don't run that.

Edit3:

OK, here is a quick lesson on arrays and their relationships with pointers:

When you use array indexing, you are really using a pointer in disguise (called a "reference"), that is automatically dereferenced. This is why instead of *(array[1]), array[1] automatically returns the value at that value.

When you have a pointer to an array, like this:

int array[5];
int *ptr = array;

Then the "array" in the second declaration is really decaying to a pointer to the first array. This is equivalent behavior to this:

int *ptr = &array[0];

When you try to access beyond what you allocated, you are really just using a pointer to other memory (which C++ won't complain about). Taking my example program above, that is equivalent to this:

int main()
{
   int array[1];
   int *ptr = array;

   for (int i = 0; i != 100000; i++, ptr++)
   {
       *ptr++ = i;
   }

   return 0; //will be lucky to ever reach this
}

The compiler won't complain because in programming, you often have to communicate with other programs, especially the operating system. This is done with pointers quite a bit.

To second Paul's response: yes, ctags (especially exuberant-ctags (http://ctags.sourceforge.net/)) is great. I have also added this to my vimrc, so I can use one tags file for an entire project:

set tags=tags;/

echo '<p>'. get_the_category( $id )[0]->name .'</p>';

is what you maybe looking for.

This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).

To avoid it, the browser check the Same-origin policy

Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:

• Copy the element on your own server (but it will be static).
• You can change your HTTP header to accept Cross-Origin content. See the Access-Control-Allow-Origin documentation for more information.

Let me try to tackle @balpha parsing problem. I would use parentheses around the multiline lamda. If there is no parentheses, the lambda definition is greedy. So the lambda in

map(lambda x:
      y = x+1
      z = x-1
      y*z,
    [1,2,3]))

returns a function that returns (y*z, [1,2,3])

But

map((lambda x:
      y = x+1
      z = x-1
      y*z)
    ,[1,2,3]))

means

map(func, [1,2,3])

where func is the multiline lambda that return y*z. Does that work?

From RFC 5321, section 2.3.11:

The standard mailbox naming convention is defined to be "local-part@domain"; contemporary usage permits a much broader set of applications than simple "user names". Consequently, and due to a long history of problems when intermediate hosts have attempted to optimize transport by modifying them, the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address.

So yes, the part before the "@" could be case-sensitive, since it is entirely under the control of the host system. In practice though, no widely used mail systems distinguish different addresses based on case.

The part after the @ sign however is the domain and according to RFC 1035, section 3.1,

"Name servers and resolvers must compare [domains] in a case-insensitive manner"

In short, you are safe to treat email addresses as case-insensitive.

You need to change each column Collation from latin1_general_ci to latin1_swedish_ci

What are the steps for that? where is AppCompat located?

Download the support library here:

http://developer.android.com/tools/support-library/setup.html

If you are using Eclipse:

Go to the tabs at the top and select ( Windows -> Android SDK Manager ). Under the 'extras' section, check 'Android Support Library' and check it for installation.

After that, the AppCompat library can be found at:

android-sdk/extras/android/support/v7/appcompat

You need to reference this AppCompat library in your Android project.

Import the library into Eclipse.

1. Right click on your Android project.
2. Select properties.
3. Click 'add...' at the bottom to add a library.
4. Select the support library
5. Clean and rebuild your project.

Here's a modified version that works for both PostgreSQL 9.1 and 9.2.

This my program in ruby . It will return arrays, each holding the subsequences summing to the provided target value.

array = [1, 3, 4, 2, 7, 8, 9]

0..array.size.times.each do |i| 
  array.combination(i).to_a.each { |a| print a if a.inject(:+) == 9} 
end

there are performance differences depending on what kind of loop you use and on what browser.

For instance:

for (var i = myArray.length-1; i >= 0; i--)

is almost twice as fast on some browsers than:

for (var i = 0; i < myArray.length; i++)

However unless your arrays are HUGE or you loop them constantly all are fast enough. I seriously doubt that array looping is a bottleneck in your project (or for any other project for that matter)

When your website is served by only one web server, for each client-server pair, a session object is created and remains in the memory of the web server. All the requests from the client go to this web server and update this session object. If some data needs to be stored in the session object over the period of interaction, it is stored in this session object and stays there as long as the session exists.

However, if your website is served by multiple web servers which sit behind a load balancer, the load balancer decides which actual (physical) web-server should each request go to. For example, if there are 3 web servers A, B and C behind the load balancer, it is possible that www.mywebsite.com/index.jsp is served from server A, www.mywebsite.com/login.jsp is served from server B and www.mywebsite.com/accoutdetails.php are served from server C.

Now, if the requests are being served from (physically) 3 different servers, each server has created a session object for you and because these session objects sit on three independent boxes, there's no direct way of one knowing what is there in the session object of the other. In order to synchronize between these server sessions, you may have to write/read the session data into a layer which is common to all - like a DB. Now writing and reading data to/from a db for this use-case may not be a good idea. Now, here comes the role of sticky-session.

If the load balancer is instructed to use sticky sessions, all of your interactions will happen with the same physical server, even though other servers are present. Thus, your session object will be the same throughout your entire interaction with this website.

To summarize, In case of Sticky Sessions, all your requests will be directed to the same physical web server while in case of a non-sticky loadbalancer may choose any webserver to serve your requests.

As an example, you may read about Amazon's Elastic Load Balancer and sticky sessions here : http://aws.typepad.com/aws/2010/04/new-elastic-load-balancing-feature-sticky-sessions.html

To return a file or filepath

URL resource = YourClass.class.getResource("abc");
File file = Paths.get(resource.toURI()).toFile(); // return a file
String filepath = Paths.get(resource.toURI()).toFile().getAbsolutePath();  // return file path

This might not be the simplest answer as compared to using array_values().

Try this

$array = array( 0 => 'string1', 2 => 'string2', 4 => 'string3', 5 => 'string4');
$arrays =$array;
print_r($array);
$array=array();
$i=0;
    foreach($arrays as $k => $item)
    {
    $array[$i]=$item;
        unset($arrays[$k]);
        $i++;

    }

print_r($array);

The other answers cover the 2 most common approaches, Xinclude and XML external entities. Microsoft has a really great writeup on why one should prefer Xinclude, as well as several example implementations. I've quoted the comparison below:

Per http://msdn.microsoft.com/en-us/library/aa302291.aspx

Why XInclude?

The first question one may ask is "Why use XInclude instead of XML external entities?" The answer is that XML external entities have a number of well-known limitations and inconvenient implications, which effectively prevent them from being a general-purpose inclusion facility. Specifically:

• An XML external entity cannot be a full-blown independent XML document—neither standalone XML declaration nor Doctype declaration is allowed. That effectively means an XML external entity itself cannot include other external entities.
• An XML external entity must be well formed XML (not so bad at first glance, but imagine you want to include sample C# code into your XML document).
• Failure to load an external entity is a fatal error; any recovery is strictly forbidden.
• Only the whole external entity may be included, there is no way to include only a portion of a document. -External entities must be declared in a DTD or an internal subset. This opens a Pandora's Box full of implications, such as the fact that the document element must be named in Doctype declaration and that validating readers may require that the full content model of the document be defined in DTD among others.

The deficiencies of using XML external entities as an inclusion mechanism have been known for some time and in fact spawned the submission of the XML Inclusion Proposal to the W3C in 1999 by Microsoft and IBM. The proposal defined a processing model and syntax for a general-purpose XML inclusion facility.

Four years later, version 1.0 of the XML Inclusions, also known as Xinclude, is a Candidate Recommendation, which means that the W3C believes that it has been widely reviewed and satisfies the basic technical problems it set out to solve, but is not yet a full recommendation.

Another good site which provides a variety of example implementations is https://www.xml.com/pub/a/2002/07/31/xinclude.html. Below is a common use case example from their site:

<book xmlns:xi="http://www.w3.org/2001/XInclude">

  <title>The Wit and Wisdom of George W. Bush</title>

  <xi:include href="malapropisms.xml"/>

  <xi:include href="mispronunciations.xml"/>

  <xi:include href="madeupwords.xml"/>

I set ANDROID_HOME to work on React Native(for Android apps) by following the following steps.

• Open Terminal (press Command+SpaceBar, type Terminal, Hit ENTER).

• Add the following 3 lines to ~/.bash_profile.

    export ANDROID_HOME=$HOME/Library/Android/sdk/
    export PATH=$PATH:$ANDROID_HOME/tools
    export PATH=$PATH:$ANDROID_HOME/platform-tools
  

• Finally execute the below command (or RESTART the system to reflect the changes made).

  source ~/.bash_profile

That's it.

Command line arguments is one way to pass the arguments in. This msdn sample is worth checking out. The MSDN Page for command line arguments is also worth reading.

From within visual studio you can set the command line arguments by Choosing the properties of your console application then selecting the Debug tab

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

The IP addresses have changed again.

github publishes the list of used IP addresses here so you can check the IP address in your message against github's list:

https://help.github.com/articles/about-github-s-ip-addresses/

Or more precisely:

https://api.github.com/meta

It looks like this (as I write this answer!):

verifiable_password_authentication  true

2   "23.20.92.3"

If you are unsure whether your IP address is contained in the above list use an CIDR calculator like http://www.subnet-calculator.com/cidr.php to show the valid IP range.

E. g. for 140.82.112.0/20 the IP range is 140.82.112.0 - 140.82.127.255

$cRepo = $em->getRepository('KaleLocationBundle:Country');

// Leave the first array blank
$countries = $cRepo->findBy(array(), array('name'=>'asc'));

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

Nesting Text components is not possible now, but you can wrap your text in a View like this:

<View style={{flexDirection: 'row', flexWrap: 'wrap'}}>
    <Text>
        {'Hello '}
    </Text>
    <Text style={{fontWeight: 'bold'}}>
        {'this is a bold text '}
    </Text>
    <Text>
        and this is not
    </Text>
</View>

I used the strings inside the brackets to force the space between words, but you can also achieve it with marginRight or marginLeft. Hope it helps.

It is probably little bit late, but I managed to solve it this way -> open with winrar and delete ECLIPSEF.RSA and ECLIPSEF.SF in META-INF folder, moreover put "Main-class: main_class_name" (without ".class") in MANIFEST.MF. Make sure that you pressed "Enter" twice after the last line, otherwise it won't work.

org.json.JSONObject quote(String data) method does the job

import org.json.JSONObject;
String jsonEncodedString = JSONObject.quote(data);

Extract from the documentation:

Encodes data as a JSON string. This applies quotes and any necessary character escaping. [...] Null will be interpreted as an empty string

Usually, you expand the parameters passed to a sub using the @_ variable:

sub test{
  my ($a, $b, $c) = @_;
  ...
}

# call the test sub with the parameters
test('alice', 'bob', 'charlie');

That's the way claimed to be correct by perlcritic.

...and the exact same arguments apply to this construct as well:

lock(typeof(SomeObject))

I wrapped my line that was crashing in a try-catch block, printed out the exception, and breaked immediately after it was printed. The exception information shown had a stack trace which pointed me to the file and line of code causing the fault to occur.

System.TypeInitializationException: The type initializer for 'Blah.blah.blah' threw an exception. 
---> System.NullReferenceException: Object reference not set to an instance of an object.

You can achieve this by controlling the formatting of the old/new/unchanged lines in GNU diff output:

diff --new-line-format="" --unchanged-line-format=""  file1 file2

The input files should be sorted for this to work. With bash (and zsh) you can sort in-place with process substitution <( ):

diff --new-line-format="" --unchanged-line-format="" <(sort file1) <(sort file2)

In the above new and unchanged lines are suppressed, so only changed (i.e. removed lines in your case) are output. You may also use a few diff options that other solutions don't offer, such as -i to ignore case, or various whitespace options (-E, -b, -v etc) for less strict matching.

Explanation

The options --new-line-format, --old-line-format and --unchanged-line-format let you control the way diff formats the differences, similar to printf format specifiers. These options format new (added), old (removed) and unchanged lines respectively. Setting one to empty "" prevents output of that kind of line.

If you are familiar with unified diff format, you can partly recreate it with:

diff --old-line-format="-%L" --unchanged-line-format=" %L" \
     --new-line-format="+%L" file1 file2

The %L specifier is the line in question, and we prefix each with "+" "-" or " ", like diff -u (note that it only outputs differences, it lacks the --- +++ and @@ lines at the top of each grouped change). You can also use this to do other useful things like number each line with %dn.

The diff method (along with other suggestions comm and join) only produce the expected output with sorted input, though you can use <(sort ...) to sort in place. Here's a simple awk (nawk) script (inspired by the scripts linked-to in Konsolebox's answer) which accepts arbitrarily ordered input files, and outputs the missing lines in the order they occur in file1.

# output lines in file1 that are not in file2
BEGIN { FS="" }                         # preserve whitespace
(NR==FNR) { ll1[FNR]=$0; nl1=FNR; }     # file1, index by lineno
(NR!=FNR) { ss2[$0]++; }                # file2, index by string
END {
    for (ll=1; ll<=nl1; ll++) if (!(ll1[ll] in ss2)) print ll1[ll]
}

This stores the entire contents of file1 line by line in a line-number indexed array ll1[], and the entire contents of file2 line by line in a line-content indexed associative array ss2[]. After both files are read, iterate over ll1 and use the in operator to determine if the line in file1 is present in file2. (This will have have different output to the diff method if there are duplicates.)

In the event that the files are sufficiently large that storing them both causes a memory problem, you can trade CPU for memory by storing only file1 and deleting matches along the way as file2 is read.

BEGIN { FS="" }
(NR==FNR) {  # file1, index by lineno and string
  ll1[FNR]=$0; ss1[$0]=FNR; nl1=FNR;
}
(NR!=FNR) {  # file2
  if ($0 in ss1) { delete ll1[ss1[$0]]; delete ss1[$0]; }
}
END {
  for (ll=1; ll<=nl1; ll++) if (ll in ll1) print ll1[ll]
}

The above stores the entire contents of file1 in two arrays, one indexed by line number ll1[], one indexed by line content ss1[]. Then as file2 is read, each matching line is deleted from ll1[] and ss1[]. At the end the remaining lines from file1 are output, preserving the original order.

In this case, with the problem as stated, you can also divide and conquer using GNU split (filtering is a GNU extension), repeated runs with chunks of file1 and reading file2 completely each time:

split -l 20000 --filter='gawk -f linesnotin.awk - file2' < file1

Note the use and placement of - meaning stdin on the gawk command line. This is provided by split from file1 in chunks of 20000 line per-invocation.

For users on non-GNU systems, there is almost certainly a GNU coreutils package you can obtain, including on OSX as part of the Apple Xcode tools which provides GNU diff, awk, though only a POSIX/BSD split rather than a GNU version.

this.dtOptions = {
    order: [],
    columnDefs: [ {
        'targets': [0], /* column index [0,1,2,3]*/
        'orderable': false, /* true or false */
    }],
    ........ rest all stuff .....
}

The above worked fine for me.

wrappingColumn has been deprecated in favour of wordWrap.

Add this line to settings.json to set wordWrap on by default:

"editor.wordWrap": "on" 

or open user settings:

Mac: ? + ,

Windows: Ctrl + ,

Then search for "wordWrap" or scroll through the 'Commonly Used' settings to find it and select 'on'

def quit(self):
    self.root.destroy()

Add parentheses after destroy to call the method.

When you use command=self.root.destroy you pass the method to Tkinter.Button without the parentheses because you want Tkinter.Button to store the method for future calling, not to call it immediately when the button is created.

But when you define the quit method, you need to call self.root.destroy() in the body of the method because by then the method has been called.

Leaflet also has LatLngBounds that even has an extend function, just like google maps.

http://leafletjs.com/reference.html#latlngbounds

So you could simply use:

var latlngbounds = new L.latLngBounds();

The rest is exactly the same.

Yes, I am fairly sure it is. One method of working around that using the standard library would be:

int index = str.toUpperCase().indexOf("FOO");

If you have entities A and B without any relation between them and there is strictly 0 or 1 B for each A, you could do:

select a, (select b from B b where b.joinProperty = a.joinProperty) from A a

This would give you an Object[]{a,b} for a single result or List<Object[]{a,b}> for multiple results.

If you aren't going to upload this to the App Store, you can also use a private method of UIView.

@interface UIView(Private)

// Later in the code
UIViewController *vc = [myView _viewControllerForAncestor];

You can either post HTML form to URL, which is mapped to servlet or insert your data in HttpServletRequest object you pass to jsp page.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

You can use this method to create hidden text field with/without form. If you need form just pass form with object status = true.

You can also add multiple hidden fields. Use this way:

The default value for InnoDB is actually pretty bad. InnoDB is very RAM dependent, you might find better result if you tweak the settings. Here's a guide that I used InnoDB optimization basic

In SQL server 2005 new datatypes were introduced: varchar(max) and nvarchar(max) They have the advantages of the old text type: they can contain op to 2GB of data, but they also have most of the advantages of varchar and nvarchar. Among these advantages are the ability to use string manipulation functions such as substring().

Also, varchar(max) is stored in the table's (disk/memory) space while the size is below 8Kb. Only when you place more data in the field, it's is stored out of the table's space. Data stored in the table's space is (usually) retrieved quicker.

In short, never use Text, as there is a better alternative: (n)varchar(max). And only use varchar(max) when a regular varchar is not big enough, ie if you expect teh string that you're going to store will exceed 8000 characters.

As was noted, you can use SUBSTRING on the TEXT datatype,but only as long the TEXT fields contains less than 8000 characters.

What you are looking for is called a Kalman Filter. It's frequently used to smooth navigational data. It is not necessarily trivial, and there is a lot of tuning you can do, but it is a very standard approach and works well. There is a KFilter library available which is a C++ implementation.

My next fallback would be least squares fit. A Kalman filter will smooth the data taking velocities into account, whereas a least squares fit approach will just use positional information. Still, it is definitely simpler to implement and understand. It looks like the GNU Scientific Library may have an implementation of this.

The result integer value is out of the range which an integer data type can hold.

Try using Int64

Given that canvas is nothing without JavaScript, use JavaScript too for sizing and positionning (you know: onresize, position:absolute, etc.)

Use @ColumnDefault() annotation. This is hibernate only though.

Something that (surprisingly) hasn't been mentioned here is simple concatenation.

Example:

foo = "seven"

print("She lives with " + foo + " small men")

Result:

She lives with seven small men

Additionally, as of Python 3, the % method is deprecated. Don't use that.

Check out java.io.ByteArrayInputStream

The reason for this error occurs is that you are using the CryptoListPresenter _presenter without initializing.

I found that CryptoListPresenter _presenter would have to be initialized to fix because _presenter.loadCurrencies() is passing through a null variable at the time of instantiation;

there are two ways to initialize

1. Can be initialized during an declaration, like this

   CryptoListPresenter _presenter = CryptoListPresenter();
   

2. In the second, initializing(with assigning some value) it when initState is called, which the framework will call this method once for each state object.

   @override
   void initState() {
     _presenter = CryptoListPresenter(...);
   }
   

If you look at Twitter's own container-app.html demo on GitHub, you'll get some ideas on using borders with their grid.

For example, here's the extracted part of the building blocks to their 940-pixel wide 16-column grid system:

.row {
    zoom: 1;
    margin-left: -20px;
}

.row > [class*="span"] {
    display: inline;
    float: left;
    margin-left: 20px;
}

.span4 {
    width: 220px;
}

To allow for borders on specific elements, they added embedded CSS to the page that reduces matching classes by enough amount to account for the border(s).

For example, to allow for the left border on the sidebar, they added this CSS in the <head> after the the main <link href="../bootstrap.css" rel="stylesheet">.

.content .span4 {
    margin-left: 0;
    padding-left: 19px;
    border-left: 1px solid #eee;
}

You'll see they've reduced padding-left by 1px to allow for the addition of the new left border. Since this rule appears later in the source order, it overrides any previous or external declarations.

I'd argue this isn't exactly the most robust or elegant approach, but it illustrates the most basic example.

Backbone.js is basically an uber-light framework that allows you to structure your Javascript code in an MVC (Model, View, Controller) fashion where...

Model is part of your code that retrieves and populates the data,

View is the HTML representation of this model (views change as models change, etc.)

and optional Controller that in this case allows you to save the state of your Javascript application via a hashbang URL, for example: http://twitter.com/#search?q=backbone.js

Some pros that I discovered with Backbone:

• No more Javascript Spaghetti: code is organized and broken down into semantically meaningful .js files which are later combined using JAMMIT

• No more jQuery.data(bla, bla): no need to store data in DOM, store data in models instead

• event binding just works

• extremely useful Underscore utility library

• backbone.js code is well documented and a great read. Opened my eyes to a number of JS code techniques.

Cons:

• Took me a while to wrap my head around it and figure out how to apply it to my code, but I'm a Javascript newbie.

Here is a set of great tutorials on using Backbone with Rails as the back-end:

p.s. There is also this wonderful Collection class that lets you deal with collections of models and mimic nested models, but I don't want to confuse you from the start.

myVideo.controls = false;

The end of the variable name is usually signified by a space or newline. But what if we don't want a space or newline after printing the variable value? The curly braces tell the shell interpreter where the end of the variable name is.

Classic Example 1) - shell variable without trailing whitespace

TIME=10

# WRONG: no such variable called 'TIMEsecs'
echo "Time taken = $TIMEsecs"

# What we want is $TIME followed by "secs" with no whitespace between the two.
echo "Time taken = ${TIME}secs"

Example 2) Java classpath with versioned jars

# WRONG - no such variable LATESTVERSION_src
CLASSPATH=hibernate-$LATESTVERSION_src.zip:hibernate_$LATEST_VERSION.jar

# RIGHT
CLASSPATH=hibernate-${LATESTVERSION}_src.zip:hibernate_$LATEST_VERSION.jar

(Fred's answer already states this but his example is a bit too abstract)

You can try something like this. Here on click of image button I toggle the imageview.

holder.imgitem.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            if(!onclick){
            mSparseBooleanArray.put((Integer) view.getTag(), true);
            holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_delete_overlay_com);
            onclick=true;}
            else if(onclick)
            {
                 mSparseBooleanArray.put((Integer) view.getTag(), false);
                  holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_selection_com);

            onclick=false;
            }
        }
    });

Is there a reason why you aren't using a table variable and the aggregate SUM operator, instead of a cursor? SQL excels at set-oriented operations. 99.87% of the time that you find yourself using a cursor, there's a set-oriented alternative that's more efficient:

declare @MonthsSale table
(
MonthNumber int,
MonthName varchar(9),
MonthSale decimal(18,2)
)

insert into @MonthsSale
select
    1, 'January', 100.00
union select    
    2, 'February', 200.00
union select    
    3, 'March', 300.00
union select    
    4, 'April', 400.00
union select    
    5, 'May', 500.00
union select    
    6, 'June', 600.00
union select    
    7, 'July', 700.00
union select    
    8, 'August', 800.00
union select    
    9, 'September', 900.00
union select    
    10, 'October', 1000.00
union select    
    11, 'November', 1100.00
union select    
    12, 'December', 1200.00

select * from @MonthsSale   
select SUM(MonthSale) as [TotalSales] from @MonthsSale

During startup in (-viewDidLoad or in storyboard) do:

self.tableView.allowsMultipleSelectionDuringEditing = NO;

Override to support conditional editing of the table view. This only needs to be implemented if you are going to be returning NO for some items. By default, all items are editable.

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    // Return YES if you want the specified item to be editable.
    return YES;
}

// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //add code here for when you hit delete
    }    
}

The most flexible approach would be using this method

Arr::sortByKeys(array $array, $keys, bool $assoc = true): array

here's why:

• You can sort by any key (also nested like 'key1.key2.key3' or ['k1', 'k2', 'k3'])

• Works both on associative and not associative arrays ($assoc flag)

• It doesn't use reference - return new sorted array

In your case it would be as simple as:

$sortedArray = Arr::sortByKeys($array, 'order');

This method is a part of this library.

 by_type_year_tag_filtered <- by_type_year_tag %>%
      dplyr:: filter(tag_name %in% c("dplyr", "ggplot2"))

Other answers are great, I just want to add... a different approach usable in PowerShell: Install GNUWin32 utils and use grep to view the lines / redirect the output to file http://gnuwin32.sourceforge.net/

This overwrites the new file every time:

grep "step[49]" logIn.log > logOut.log 

This appends the log output, in case you overwrite the logIn file and want to keep the data:

grep "step[49]" logIn.log >> logOut.log 

Note: to be able to use GNUWin32 utils globally you have to add the bin folder to your system path.

Server side

It depends on which language you use.

In Java/Java EE:

• Jetty 7.0 supports it (very easy to use) V 7.5 supports RFC6455 - Jetty 9.1 supports javax.websocket / JSR 356)
• GlassFish 3.0 (very low level and sometimes complex), Glassfish 3.1 has new refactored Websocket Support which is more developer friendly V 3.1.2 supports RFC6455
• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete. See Arun GUPTA's article WebSocket and Java EE 7 - Getting Ready for JSR 356 (TOTD #181) and QCon presentation (from 00:37:36 to 00:46:53) for more information on progress.

I think you want to use typeof() here:

function f(id, parameters, callback) {
  console.log(typeof(parameters)+" "+typeof(callback));
}

f("hi", {"a":"boo"}, f); //prints "object function"
f("hi", f, {"a":"boo"}); //prints "function object"

isset() vs empty() vs is_null()

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

You can do it by using name attibute, class, id or just universal checkbox; If you want to count only checked number of checkbox.

By the class name :

var countChk = $('checkbox.myclassboxName:checked').length;

By name attribute :

var countByName= $('checkbox[name=myAllcheckBoxName]:checked').length;

Complete code

$('checkbox.className').blur(function() {
    //count only checked checkbox 
    $('checkbox[name=myAllcheckBoxName]:checked').length;
});

you can use just

     <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version></version>
    </dependency>

Is it very expensive to do this by json convert? But at least you have a 2 line solution and its generic. It does not matter eather if your datatable contains more or less fields than the object class:

Dim sSql = $"SELECT '{jobID}' AS ConfigNo, 'MainSettings' AS ParamName, VarNm AS ParamFieldName, 1 AS ParamSetId, Val1 AS ParamValue FROM StrSVar WHERE NmSp = '{sAppName} Params {jobID}'"
            Dim dtParameters As DataTable = DBLib.GetDatabaseData(sSql)

            Dim paramListObject As New List(Of ParameterListModel)()

            If (Not dtParameters Is Nothing And dtParameters.Rows.Count > 0) Then
                Dim json = Newtonsoft.Json.JsonConvert.SerializeObject(dtParameters).ToString()

                paramListObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Of List(Of ParameterListModel))(json)
            End If

If non of above works for you, then it is worth to check if you have any packages under Preference > Editor > Code Style > Java > Imports > Packages to Use Import with "*"

If you have IIS Express (with Visual Studio):

To enable the SSL within IIS Express, you have to just set “SSL Enabled = true” in the project properties window.

See the steps and pictures at this code project.

IIS Express will generate a certificate for you (you'll be prompted for it, etc.). Note that depending on configuration the site may still automatically start with the URL rather than the SSL URL. You can see the SSL URL - note the port number and replace it in your browser address bar, you should be able to get in and test.

From there you can right click on your project, click property pages, then start options and assign the start URL - put the new https with the new port (usually 44301 - notice the similarity to port 443) and your project will start correctly from then on.

Instead of running the script using . run2.sh, you can run it using sh run2.sh or bash run2.sh

A new sub-shell will be started, to run the script then, it will be closed at the end of the script leaving the other shell opened.

You can do something like

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

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

typeof result[k] === "object"

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

git cherry-pick C

where C is the commit hash for C. This applies the old commit on top of the newest one.

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

pass like this

date('Y-m-d H:i:s','1299762201428')

Python 3.x for large (but not too large) DataFrames

Maybe because I have an older version of pandas but on Jupyter notebook this work for me

import pandas as pd
from IPython.core.display import HTML

df=pd.read_pickle('Data1')
display(HTML(df.to_html()))

You can use curly braces to control the number of occurrences. For example, this means 0 to 10:

/^[a-z]{0,10}$/

The options are:

• {3} Exactly 3 occurrences;
• {6,} At least 6 occurrences;
• {2,5} 2 to 5 occurrences.

See the regular expression reference.

Your expression had a + after the closing curly brace, hence the error.

First, the error you're getting is due to where you're using the COUNT function -- you can't use an aggregate (or group) function in the WHERE clause.

Second, instead of using a subquery, simply join the table to itself:

SELECT a.pid 
FROM Catalog as a LEFT JOIN Catalog as b USING( pid )
WHERE a.sid != b.sid
GROUP BY a.pid

Which I believe should return only rows where at least two rows exist with the same pid but there is are at least 2 sids. To make sure you get back only one row per pid I've applied a grouping clause.

If you need a fully qualified domain name and have no HTTP request, on Linux, you could use:

var child_process = require("child_process");

child_process.exec("hostname -f", function(err, stdout, stderr) {
  var hostname = stdout.trim();
});

Update one table using Inner Join

  UPDATE Table1 SET name=ml.name
FROM table1 t inner JOIN
Table2 ml ON t.ID= ml.ID  

In the same spirit as 4ndrew's answer:

listOfNames="RA
RB
R C
RD"

# To allow for other whitespace in the string:
# 1. add double quotes around the list variable, or
# 2. see the IFS note (under 'Side Notes')

for databaseName in "$listOfNames"   #  <-- Note: Added "" quotes.
do
  echo "$databaseName"  # (i.e. do action / processing of $databaseName here...)
done

# Outputs
# RA
# RB
# R C
# RD

B. No whitespace in the names:

listOfNames="RA
RB
R C
RD"

for databaseName in $listOfNames  # Note: No quotes
do
  echo "$databaseName"  # (i.e. do action / processing of $databaseName here...)
done

# Outputs
# RA
# RB
# R
# C
# RD

Notes

1. In the second example, using listOfNames="RA RB R C RD" has the same output.

Other ways to bring in data include:

• stdin (listed below),
• variables,
• an array (the accepted answer),
• a file...

Read from stdin

# line delimited (each databaseName is stored on a line)
while read databaseName
do
  echo "$databaseName"  # i.e. do action / processing of $databaseName here...
done # <<< or_another_input_method_here

2. the bash IFS "field separator to line" [1] delimiter can be specified in the script to allow other whitespace (i.e. IFS='\n', or for MacOS IFS='\r')
3. I like the accepted answer also :) -- I've include these snippets as other helpful ways that also answer the question.
4. Including #!/bin/bash at the top of the script file indicates the execution environment.
5. It took me months to figure out how to code this simply :)

Other Sources (while read loop)

your $(this).val() has no scope in your ajax call, because its not in change event function scope

May be you implemented that ajax call in your change event itself first, in that case it works fine. but when u created a function and calling that funciton in change event, scope for $(this).val() is not valid.

simply get the value using id selector instead of

$(#CourseSelect).val()

whole code should be like this:

 $(document).ready(function () 
{
    $("#CourseSelect").change(loadTeachers);
    loadTeachers();
});

function loadTeachers()
{
    $.ajax({ type:'GET', url:'/Manage/getTeachers/' + $(#CourseSelect).val(), dataType:'json', cache:false,
        success:function(data)
        { 
            $('#TeacherSelect').get(0).options.length = 0;    

            $.each(data, function(i, teacher) 
            {
                var option = $('<option />');
                option.val(teacher.employeeId);
                option.text(teacher.name);
                $('#TeacherSelect').append(option);
            });
        }, error:function(){ alert("Error while getting results"); }
    });
}

Simply declare it as below if you want to us the STL queue container.

std::queue<myclass*> my_queue;

How about using the replaceAll() method?

Just want to point out that in case you have a MemoryStream you already have memorystream.ToArray() for that.

Also, if you are dealing with streams of unknown or different subtypes and you can receive a MemoryStream, you can relay on said method for those cases and still use the accepted answer for the others, like this:

public static byte[] StreamToByteArray(Stream stream)
{
    if (stream is MemoryStream)
    {
        return ((MemoryStream)stream).ToArray();                
    }
    else
    {
        // Jon Skeet's accepted answer 
        return ReadFully(stream);
    }
}

Use a StringWriter instead of a StreamWriter:

public static string SerializeObject<T>(this T toSerialize)
{
    XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType());

    using(StringWriter textWriter = new StringWriter())
    {
        xmlSerializer.Serialize(textWriter, toSerialize);
        return textWriter.ToString();
    }
}

Note, it is important to use toSerialize.GetType() instead of typeof(T) in XmlSerializer constructor: if you use the first one the code covers all possible subclasses of T (which are valid for the method), while using the latter one will fail when passing a type derived from T.    Here is a link with some example code that motivate this statement, with XmlSerializer throwing an Exception when typeof(T) is used, because you pass an instance of a derived type to a method that calls SerializeObject that is defined in the derived type's base class: http://ideone.com/1Z5J1.

Also, Ideone uses Mono to execute code; the actual Exception you would get using the Microsoft .NET runtime has a different Message than the one shown on Ideone, but it fails just the same.

When you create a cookie via PHP die Default Value is 0, from the manual:

If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes)

Otherwise you can set the cookies lifetime in seconds as the third parameter:

http://www.php.net/manual/en/function.setcookie.php

But if you mean to get the remaining lifetime of an already existing cookie, i fear that, is not possible (at least not in a direct way).

I would recommend trying the Response.TransferFile() method then a Response.Flush() and Response.End() for serving your large files.

With Chinese text, I tried to use the Charset UTF-16 and lucklily it work.

Hope this could help!

PrintWriter out = new PrintWriter( file, "UTF-16" );

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

Using Mysqli::$insert_id:

$sql="INSERT INTO table (col1, col2, col3) VALUES (val1, val2, val3)";
$mysqli->query($sql);
$last_inserted_id=$mysqli->insert_id; // returns last ID

Using PDO::lastInsertId:

$sql="INSERT INTO table (col1, col2, col3) VALUES (val1, val2, val3)";
$database->query($sql);
$last_inserted_id=$database->lastInsertId(); // returns last ID

you should add servler-api.jar file in WEB-INF/lib folder

                firstName.setText("Some Text");
            }
        });
    }

try like this.

My simple solution is to style hr with css to have zero top & bottom margins, zero border, 1 pixel height and contrasting background color. This can be done by setting the style directly or by defining a class, for example, like:

.thin_hr {
margin-top:0;
margin-bottom:0;
border:0;
height:1px;
background-color:black;
}

You need to include iostream

#include <iostream>
using namespace std;

A DataTable or DataSet object will have a Select Method that will return a DataRow array of results based on the query passed in as it's parameter.

Looking at your requirement your filterexpression will have to be somewhat general to make this work.

myDataTable.Select("columnName1 like '%" + value + "%'");

It can be done without printing magic strings and using TextFinder. Here's some info on it.

Basically you need a .jar file from http://yourserver.com/cli available in shell scripts, then you can use the following command to mark a build unstable:

java -jar jenkins-cli.jar set-build-result unstable

To mark build unstable on error, you can use:

failing_cmd cmd_args || java -jar jenkins-cli.jar set-build-result unstable

The problem is that jenkins-cli.jar has to be available from shell script. You can either put it in easy-to-access path, or download in via job's shell script:

wget ${JENKINS_URL}jnlpJars/jenkins-cli.jar

To use both is a nice answer; it's not a question of either or.

The advantage of using both is that the CSS will hide the element immediately when the page loads. The jQuery .hide will flash the element for a quarter of a second then hide it.

In the case when we want to have the element not shown when the page loads we can use CSS and set display:none & use the jQuery .hide(). If we plan to toggle the element we can use jQuery toggle.

You can try something like this.

<button class="button" ng-disabled="(!data.var1 && !data.var2) ? false : true">
</button>

Its working fine for me.

Static methods are not associated with an instance, so they can not access any non-static fields in the class.

You would use a static method if the method does not use any fields (or only static fields) of a class.

If any non-static fields of a class are used you must use a non-static method.

What if you set the timezone of the role you are using?

ALTER ROLE my_db_user IN DATABASE my_database
    SET "TimeZone" TO 'UTC';

Will this be of any use?

In case it helps, I've ran into this problem when passing null into a parameter for a generic TValue, to get around this you have to cast your null values:

(string)null

(int)null

etc.

Consider the outcome of the tool 'stat':

  File: `infolog.txt'
  Size: 694         Blocks: 8          IO Block: 4096   regular file
Device: 801h/2049d  Inode: 11635578    Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1000/     fdr)   Gid: ( 1000/     fdr)
Access: 2009-01-01 22:04:15.000000000 -0800
Modify: 2009-01-01 22:05:05.000000000 -0800
Change: 2009-01-01 22:05:05.000000000 -0800

You can see here the three dates for Access/modify/change. There is no created date. You can only really be sure when the file contents were modified (the "modify" field) or its inode changed (the "change" field).

Examples of when both fields get updated:

"Modify" will be updated if someone concatenated extra information to the end of the file.

"Change" will be updated if someone changed permissions via chmod.

For the completeness's sake.

When zipped lists' lengths are not equal. The result list's length will become the shortest one without any error occurred

>>> a = [1]
>>> b = ["2", 3]
>>> zip(a,b)
[(1, '2')]

Actually, ojdbc14.jar doesn't really say anything about the real version of the driver (see JDBC Driver Downloads), except that it predates Oracle 11g. In such situation, you should provide the exact version.

Anyway, I think you'll find some explanation in What is going on with DATE and TIMESTAMP? In short, they changed the behavior in 9.2 drivers and then again in 11.1 drivers.

This might explain the differences you're experiencing (and I suggest using the most recent version i.e. the 11.2 drivers).

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

A solution which uses lynx and wget.

Note: Lynx has to have been compiled with the --enable-persistent-cookies flag for this to work

When you want to use wget to download some file from a site which requires login, you just need a cookie file. In order to generate the cookie file, I choose lynx. lynx is a text web browser. First you need a configure file for lynx to save cookie. Create a file lynx.cfg. Write these configuration into the file.

SET_COOKIES:TRUE
ACCEPT_ALL_COOKIES:TRUE
PERSISTENT_COOKIES:TRUE
COOKIE_FILE:cookie.file

Then start lynx with this command:

lynx -cfg=lynx.cfg http://the.site.com/login

After you input the username and password, and select 'preserve me on this pc' or something similar. If login successfully, you will see a beautiful text web page of the site. And you logout. The in the current directory, you will find a cookie file named as cookie.file. This is what we need for wget.

Then wget can download file from the site with this command.

wget --load-cookies ./cookie.file http://the.site.com/download/we-can-make-this-world-better.tar.gz

It appears that you're calling DateLastUpdated from within an active query using the same EF context and DateLastUpdate issues a command to the data store itself. Entity Framework only supports one active command per context at a time.

You can refactor your above two queries into one like this:

return accounts.AsEnumerable()
        .Select((account, index) => new AccountsReport()
        {
          RecordNumber = FormattedRowNumber(account, index + 1),
          CreditRegistryId = account.CreditRegistryId,
          DateLastUpdated = (
                                                from h in context.AccountHistory 
                                                where h.CreditorRegistryId == creditorRegistryId 
                              && h.AccountNo == accountNo 
                                                select h.LastUpdated).Max(),
          AccountNumber = FormattedAccountNumber(account.AccountType, account.AccountNumber)
        })
        .OrderBy(c=>c.FormattedRecordNumber)
        .ThenByDescending(c => c.StateChangeDate);

I also noticed you're calling functions like FormattedAccountNumber and FormattedRecordNumber in the queries. Unless these are stored procs or functions you've imported from your database into the entity data model and mapped correct, these will also throw excepts as EF will not know how to translate those functions in to statements it can send to the data store.

Also note, calling AsEnumerable doesn't force the query to execute. Until the query execution is deferred until enumerated. You can force enumeration with ToList or ToArray if you so desire.

c=0
words = ['challa','reddy','challa']

for idx, word in enumerate(words):
    if idx==0:
        firstword=word
        print(firstword)
    elif idx == len(words)-1:
        lastword=word
        print(lastword)
        if firstword==lastword:
            c=c+1
            print(c)

You could also implement rich comparison via __eq__ method for your Test class and use in operator. Not sure if this is the best stand-alone way, but in case if you need to compare Test instances based on value somewhere else, this could be useful.

class Test:
    def __init__(self, value):
        self.value = value

    def __eq__(self, other):
        """To implement 'in' operator"""
        # Comparing with int (assuming "value" is int)
        if isinstance(other, int):
            return self.value == other
        # Comparing with another Test object
        elif isinstance(other, Test):
            return self.value == other.value

import random

value = 5

test_list = [Test(random.randint(0,100)) for x in range(1000)]

if value in test_list:
    print "i found it"

Better than all above is ever to use Standard C specification for struct initialization:

struct StructType structVar = {0};

Here are all bits zero (ever).

Enter super user mode, and cd into the directory that you are not permissioned to go into. Sudo requires administrator password.

sudo su
cd directory

You can do the following which escapes both PHP and MySQL.

<?
$text = '<a href="javascript:window.open(\\\'http://www.google.com\\\');"></a>';
?> 

This will reflect MySQL as

<a href="javascript:window.open('http://www.google.com');"></a>

How does it work?

We know that both PHP and MySQL apostrophes can be escaped with backslash and then apostrophe.

\'

Because we are using PHP to insert into MySQL, we need PHP to still write the backslash to MySQL so it too can escape it. So we use the PHP escape character of backslash-backslash together with backslash-apostrophe to achieve this.

\\\'

Simply run:

user@host:~ $ echo set autoindent >> .vimrc

public static void main(String[] args) {
    List<String> strlist = new ArrayList<String>();
    strlist.add("sdfs1");
    strlist.add("sdfs2");

    String[] strarray = new String[strlist.size()]
    strlist.toArray(strarray );

    System.out.println(strarray);


}

Here is @DwB solution upgraded to Commons CLI 1.3.1 compliance (replaced deprecated components OptionBuilder and GnuParser). The Apache documentation uses examples that in real life have unmarked/bare arguments but ignores them. Thanks @DwB for showing how it works.

I was having a similar problem. I was not using the ACL stuff, so I didn't need s3:PutObjectAcl.

In my case, I was doing (in Serverless Framework YML):

- Effect: Allow
  Action:
    - s3:PutObject
  Resource: "arn:aws:s3:::MyBucketName"

Instead of:

- Effect: Allow
  Action:
    - s3:PutObject
  Resource: "arn:aws:s3:::MyBucketName/*"

Which adds a /* to the end of the bucket ARN.

Hope this helps.

I used numpy to generate the array, but list of lists array should work similarly.

import numpy as np
def printArray(args):
    print "\t".join(args)

n = 10

Array = np.zeros(shape=(n,n)).astype('int')

for row in Array:
    printArray([str(x) for x in row])

If you want to only print certain indices:

import numpy as np
def printArray(args):
    print "\t".join(args)

n = 10

Array = np.zeros(shape=(n,n)).astype('int')

i_indices = [1,2,3]
j_indices = [2,3,4]

for i in i_indices:printArray([str(Array[i][j]) for j in j_indices])

I think I have an idea. This has been doing my nut in too and I'm still having trouble getting it to display in Chrome.

Save document(name.docx) in word as single file webpage (name.mht) In your html use

<iframe src= "name.mht" width="100%" height="800"> </iframe>

Alter the heights and widths as you see fit.

If you're like me you just want to modify some of the colors in AppCompat, and the only color you need to uniquely change in the dialog is the background. Then all you need to do is set a color for colorBackgroundFloating.

Here's my basic theme that simply modifies some colors with no nested themes:

    <style name="AppTheme" parent="Theme.AppCompat">
        <item name="colorPrimary">@color/theme_colorPrimary</item>
        <item name="colorPrimaryDark">@color/theme_colorPrimaryDark</item>
        <item name="colorAccent">@color/theme_colorAccent</item>
        <item name="colorControlActivated">@color/theme_colorControlActivated</item>
        <item name="android:windowBackground">@color/theme_bg</item>
        <item name="colorBackgroundFloating">@color/theme_dialog_bg</item><!-- Dialog background color -->
        <item name="colorButtonNormal">@color/theme_colorPrimary</item>
        <item name="colorControlHighlight">@color/theme_colorAccent</item>
    </style>

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

There is a Console tab at the bottom of the SQL (query) screen. By default it is not expanded, but once clicked on it should expose tabs for Options, History and Clear. Click on history.

The Query history length is set from within Page Related Settings which found by clicking on the gear wheel at the top right of screen.

This is correct for PHP version 4.5.1-1

You can read an article i have written for joins in LINQ here

var query = 
from  u in Repo.T_Benutzer
join bg in Repo.T_Benutzer_Benutzergruppen
    on u.BE_ID equals bg.BEBG_BE
into temp
from j in temp.DefaultIfEmpty()
select new
{
    BE_User = u.BE_User,
    BEBG_BG = (int?)j.BEBG_BG// == null ? -1 : j.BEBG_BG
            //, bg.Name 
}

The following is the equivalent using extension methods:

var query = 
Repo.T_Benutzer
.GroupJoin
(
    Repo.T_Benutzer_Benutzergruppen,
    x=>x.BE_ID,
    x=>x.BEBG_BE,
    (o,i)=>new {o,i}
)
.SelectMany
(
    x => x.i.DefaultIfEmpty(),
    (o,i) => new
    {
        BE_User = o.o.BE_User,
        BEBG_BG = (int?)i.BEBG_BG
    }
);

In Python, you can copy the files using

• shutil module
• os module
• subprocess module

import os
import shutil
import subprocess

1) Copying files using shutil module

shutil.copyfile signature

shutil.copyfile(src_file, dest_file, *, follow_symlinks=True)

# example    
shutil.copyfile('source.txt', 'destination.txt')

shutil.copy signature

shutil.copy(src_file, dest_file, *, follow_symlinks=True)

# example
shutil.copy('source.txt', 'destination.txt')

shutil.copy2 signature

shutil.copy2(src_file, dest_file, *, follow_symlinks=True)

# example
shutil.copy2('source.txt', 'destination.txt')  

shutil.copyfileobj signature

shutil.copyfileobj(src_file_object, dest_file_object[, length])

# example
file_src = 'source.txt'  
f_src = open(file_src, 'rb')

file_dest = 'destination.txt'  
f_dest = open(file_dest, 'wb')

shutil.copyfileobj(f_src, f_dest)  

2) Copying files using os module

os.popen signature

os.popen(cmd[, mode[, bufsize]])

# example
# In Unix/Linux
os.popen('cp source.txt destination.txt') 

# In Windows
os.popen('copy source.txt destination.txt')

os.system signature

os.system(command)


# In Linux/Unix
os.system('cp source.txt destination.txt')  

# In Windows
os.system('copy source.txt destination.txt')

3) Copying files using subprocess module

subprocess.call signature

subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False)

# example (WARNING: setting `shell=True` might be a security-risk)
# In Linux/Unix
status = subprocess.call('cp source.txt destination.txt', shell=True) 

# In Windows
status = subprocess.call('copy source.txt destination.txt', shell=True)

subprocess.check_output signature

subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False)

# example (WARNING: setting `shell=True` might be a security-risk)
# In Linux/Unix
status = subprocess.check_output('cp source.txt destination.txt', shell=True)

# In Windows
status = subprocess.check_output('copy source.txt destination.txt', shell=True)

DI gives you a composition root, which is a single centralized location for wiring up your object graph. This tends to make object dependencies very explicit, because objects ask for exactly what they need and there is only one place to get it.

A composition root is a clean and straightforward separation of concerns. Objects being injected should have no dependency on the DI mechanism, whether that be a third-party container or a DIY DI. The DI should be invisible.

Factories tend to be more distributed. Different objects use different factories and the factories represent an additional layer of indirection between the objects and their actual dependencies. This additional layer adds its own dependencies to the object graph. Factories are not invisible. A Factory is a middleman.

For this reason, updating factories is more problematic: since factories are a dependency of the business logic, modifying them can have a ripple effect. A composition root is not a dependency of the business logic, so it can be modified in isolation.

The GoF mentions the difficulty of updating Abstract Factories. Part of their explanation is quoted in an answer here. Contrasting DI with Factories also has a lot in common with the question, Is ServiceLocator an anti-pattern?

Ultimately, the answer of which to choose may be opinionated; but I think it boils down to a Factory being a middleman. The question is whether that middleman pulls its weight by adding additional value beyond just supplying a product. Because if you can get that same product without the middleman, then why not cut the middleman out?

A diagram helps to illustrate the difference.

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

HTML/JSP Markup:

<form:option 
data-libelle="${compte.libelleCompte}" 
data-raison="${compte.libelleSociale}"   data-rib="${compte.numeroCompte}"                              <c:out value="${compte.libelleCompte} *MAD*"/>
</form:option>

JQUERY CODE: Event: change

var $this = $(this);
var $selectedOption = $this.find('option:selected');
var libelle = $selectedOption.data('libelle');

To have a element libelle.val() or libelle.text()

I've used it in code before, though only to interface with legacy code. This was a Mac OS X Cocoa application that needed to load preference files from an earlier, Carbon version (which was itself backwards-compatible with the original M68k System 6.5 version...you get the idea). The preference files in the original version were a binary dump of a configuration structure, that used the #pragma pack(1) to avoid taking up extra space and saving junk (i.e. the padding bytes that would otherwise be in the structure).

The original authors of the code had also used #pragma pack(1) to store structures that were used as messages in inter-process communication. I think the reason here was to avoid the possibility of unknown or changed padding sizes, as the code sometimes looked at a specific portion of the message struct by counting a number of bytes in from the start (ewww).

For HttpEntity, the below answer works

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

For reference: How to POST form data with Spring RestTemplate?

I achieved 1600k concurrent idle socket connections, and at the same time 57k req/s on a Linux desktop (16G RAM, I7 2600 CPU). It's a single thread http server written in C with epoll. Source code is on github, a blog here.

Edit:

I did 600k concurrent HTTP connections (client & server) on both the same computer, with JAVA/Clojure . detail info post, HN discussion: http://news.ycombinator.com/item?id=5127251

The cost of a connection(with epoll):

• application need some RAM per connection
• TCP buffer 2 * 4k ~ 10k, or more
• epoll need some memory for a file descriptor, from epoll(7)

Each registered file descriptor costs roughly 90 bytes on a 32-bit kernel, and roughly 160 bytes on a 64-bit kernel.

You will have to save the relationship on the server side. The value is the only part that is transmitted when the form is posted. You could do something nasty like...

<option value="2|Dog">Dog</option>

Then split the result apart if you really wanted to, but that is an ugly hack and a waste of bandwidth assuming the numbers are truly unique and have a one to one relationship with the text.

The best way would be to create an array, and loop over the array to create the HTML. Once the form is posted you can use the value to look up the text in that same array.

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

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

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

npm run command-name or npm run-script command-name ( ex. npm run build ) is also a cli-command predefined to run your custom scripts with the name specified in place of "command-name". So, in this case npm run build is a custom script command with the name "build" and will do anything specified inside it (for instance echo 'hello world' given in below example package.json).

Ponits to note::

1. One more thing, npm build and npm run build are two different things, npm run build will do custom work written inside package.json and npm build is a pre-defined script (not available to use directly)

2. You cannot specify some thing inside custom build script (npm run build) script and expect npm build to do the same. Try following thing to verify in your package.json:

   { "name": "demo", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "build":"echo 'hello build'" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": {}, "dependencies": {} }

and run npm run build and npm build one by one and you will see the difference. For more about commands kindly follow npm documentation.

Cheers!!

When you inline an initial value for a variable it will be done implicitly in the constructor anyway.

I would argue that this syntax was best practice in C# up to 5:

class Person 
{
    public Person()
    {
        //do anything before variable assignment

        //assign initial values
        Name = "Default Name";

        //do anything after variable assignment
    }
    public string Name { get; set; }
}

As this gives you clear control of the order values are assigned.

As of C#6 there is a new way:

public string Name { get; set; } = "Default Name";

Both works fine. But according to the Apache docs you should avoid using mod_rewrite for simple redirections, and use Redirect instead. So according to them, you should preferably do:

<VirtualHost *:80>
    ServerName www.example.com
    Redirect / https://www.example.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.com
    # ... SSL configuration goes here
</VirtualHost>

The first / after Redirect is the url, the second part is where it should be redirected.

You can also use it to redirect URLs to a subdomain: Redirect /one/ http://one.example.com/

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

when try to make foreign key when using laravel migration

like this example:

user table

    public function up()
{
    Schema::create('flights', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->TinyInteger('color_id')->unsigned();
        $table->foreign('color_id')->references('id')->on('colors');
        $table->timestamps();
    });
}

colors table

    public function up()
{
    Schema::create('flights', function (Blueprint $table) {
        $table->increments('id');
        $table->string('color');
        $table->timestamps();
    });
}

sometimes properties didn't work

[PDOException]
SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint

this error happened because the foreign key (type) in [user table] is deferent from primary key (type) in [colors table]

To solve this problem should change the primary key in [colors table]

$table->tinyIncrements('id');

When you use primary key $table->Increments('id');

you should use Integer as a foreign key

    $table-> unsignedInteger('fk_id');
    $table->foreign('fk_id')->references('id')->on('table_name');

When you use primary key $table->tinyIncrements('id');

you should use unsignedTinyInteger as a foreign key

    $table-> unsignedTinyInteger('fk_id');
    $table->foreign('fk_id')->references('id')->on('table_name');

When you use primary key $table->smallIncrements('id');

you should use unsignedSmallInteger as a foreign key

    $table-> unsignedSmallInteger('fk_id');
    $table->foreign('fk_id')->references('id')->on('table_name');

When you use primary key $table->mediumIncrements('id');

you should use unsignedMediumInteger as a foreign key

    $table-> unsignedMediumInteger('fk_id');
    $table->foreign('fk_id')->references('id')->on('table_name');

Problem: Wamp Won't Turn Green & VCRUNTIME140.dll error

Solved:)

You need C++ Redistributable for Visual Studio 2015 RC. Try to download the file, vc_redist.x64.exe from here, https://www.microsoft.com/en-us/download/details.aspx?id=48145

if you already installed then uninstalled it first

1. I installed the vc_redist.x64.exe (if you OS is 32 bit then you should download vc_redist.x86.exe)
2. then installed the wampserver (if you already installed then unsintalled it first)

As of May 2018, you can find the full list here: https://developers.facebook.com/docs/reference/opengraph#object-type

game.achievement This object type represents a specific achievement in a game. An app must be in the 'Games' category in App Dashboard to be able to use this object type. Every achievement has a game:points value associate with it. This is not related to the points the user has scored in the game, but is a way for the app to indicate the relative importance and scarcity of different achievements: * Each game gets a total of 1,000 points to distribute across its achievements * Each game gets a maximum of 1,000 achievements * Achievements which are scarcer and have higher point values will receive more distribution in Facebook's social channels. For example, achievements which have point values of less than 10 will get almost no distribution. Apps should aim for between 50-100 achievements consisting of a mix of 50 (difficult), 25 (medium), and 10 (easy) point value achievements Read more on how to use achievements in this guide.

Here is a great article, You can implement common library and just use below code to import any HTML files in one line.

<head>
   <link rel="import" href="warnings.html">
</head>

You can also try Google Polymer

The CSS solution is: http://www.w3.org/TR/css3-multicol/

The browser support is exactly what you'd expect..

It works "everywhere" except Internet Explorer 9 or older: http://caniuse.com/multicolumn

ul {
    -moz-column-count: 4;
    -moz-column-gap: 20px;
    -webkit-column-count: 4;
    -webkit-column-gap: 20px;
    column-count: 4;
    column-gap: 20px;
}

See: http://jsfiddle.net/pdExf/

If IE support is required, you'll have to use JavaScript, for example:

http://welcome.totheinter.net/columnizer-jquery-plugin/

Another solution is to fallback to normal float: left for only IE. The order will be wrong, but at least it will look similar:

See: http://jsfiddle.net/NJ4Hw/

<!--[if lt IE 10]>
<style>
li {
    width: 25%;
    float: left
}
</style>
<![endif]-->

You could apply that fallback with Modernizr if you're already using it.

As it is said, a picture is worth 1000 words. I say: some code is better than 1000 words. Here's the source code of HashMap. Get method:

/**
     * Implements Map.get and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @return the node, or null if none
     */
    final Node<K,V> getNode(int hash, Object key) {
        Node<K,V>[] tab; Node<K,V> first, e; int n; K k;
        if ((tab = table) != null && (n = tab.length) > 0 &&
            (first = tab[(n - 1) & hash]) != null) {
            if (first.hash == hash && // always check first node
                ((k = first.key) == key || (key != null && key.equals(k))))
                return first;
            if ((e = first.next) != null) {
                if (first instanceof TreeNode)
                    return ((TreeNode<K,V>)first).getTreeNode(hash, key);
                do {
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        return e;
                } while ((e = e.next) != null);
            }
        }
        return null;
    }

So it becomes clear that hash is used to find the "bucket" and the first element is always checked in that bucket. If not, then equals of the key is used to find the actual element in the linked list.

Let's see the put() method:

  /**
     * Implements Map.put and related methods
     *
     * @param hash hash for key
     * @param key the key
     * @param value the value to put
     * @param onlyIfAbsent if true, don't change existing value
     * @param evict if false, the table is in creation mode.
     * @return previous value, or null if none
     */
    final V putVal(int hash, K key, V value, boolean onlyIfAbsent,
                   boolean evict) {
        Node<K,V>[] tab; Node<K,V> p; int n, i;
        if ((tab = table) == null || (n = tab.length) == 0)
            n = (tab = resize()).length;
        if ((p = tab[i = (n - 1) & hash]) == null)
            tab[i] = newNode(hash, key, value, null);
        else {
            Node<K,V> e; K k;
            if (p.hash == hash &&
                ((k = p.key) == key || (key != null && key.equals(k))))
                e = p;
            else if (p instanceof TreeNode)
                e = ((TreeNode<K,V>)p).putTreeVal(this, tab, hash, key, value);
            else {
                for (int binCount = 0; ; ++binCount) {
                    if ((e = p.next) == null) {
                        p.next = newNode(hash, key, value, null);
                        if (binCount >= TREEIFY_THRESHOLD - 1) // -1 for 1st
                            treeifyBin(tab, hash);
                        break;
                    }
                    if (e.hash == hash &&
                        ((k = e.key) == key || (key != null && key.equals(k))))
                        break;
                    p = e;
                }
            }
            if (e != null) { // existing mapping for key
                V oldValue = e.value;
                if (!onlyIfAbsent || oldValue == null)
                    e.value = value;
                afterNodeAccess(e);
                return oldValue;
            }
        }
        ++modCount;
        if (++size > threshold)
            resize();
        afterNodeInsertion(evict);
        return null;
    }

It's slightly more complicated, but it becomes clear that the new element is put in the tab at the position calculated based on hash:

i = (n - 1) & hash here i is the index where the new element will be put (or it is the "bucket"). n is the size of the tab array (array of "buckets").

First, it is tried to be put as the first element of in that "bucket". If there is already an element, then append a new node to the list.

If you get UnsupportedOperationException from using one of ther answer above and your List is created from Arrays.asList(), it is because you can't edit such List.

To fix, wrap the Arrays.asList() inside new LinkedList<String>():

    List<String> list = new LinkedList<String>(Arrays.asList(split));

how can scrapy be used to scrape this dynamic data so that I can use it?

I wonder why no one has posted the solution using Scrapy only.

Check out the blog post from Scrapy team SCRAPING INFINITE SCROLLING PAGES . The example scraps http://spidyquotes.herokuapp.com/scroll website which uses infinite scrolling.

The idea is to use Developer Tools of your browser and notice the AJAX requests, then based on that information create the requests for Scrapy.

import json
import scrapy


class SpidyQuotesSpider(scrapy.Spider):
    name = 'spidyquotes'
    quotes_base_url = 'http://spidyquotes.herokuapp.com/api/quotes?page=%s'
    start_urls = [quotes_base_url % 1]
    download_delay = 1.5

    def parse(self, response):
        data = json.loads(response.body)
        for item in data.get('quotes', []):
            yield {
                'text': item.get('text'),
                'author': item.get('author', {}).get('name'),
                'tags': item.get('tags'),
            }
        if data['has_next']:
            next_page = data['page'] + 1
            yield scrapy.Request(self.quotes_base_url % next_page)

var result = from cx in CustomerList
         group cx by cx.GroupID into cxGroup
     orderby cxGroup.Key
     select cxGroup; 

foreach (var cxGroup in result) { 
Console.WriteLine(String.Format("GroupID = {0}", cxGroup.Key)); 
  foreach (var cx in cxGroup) { 
    Console.WriteLine(String.Format("\tUserID = {0}, UserName = {1}, GroupID = {2}", 
      new object[] { cx.ID, cx.Name, cx.GroupID })); 
  }
}

The bootstrap-live-customizer is a good resource for customising your own bootstrap theme and seeing the results live as you customise. Using this website its very easy to just edit the font and then download the updated .css file.

Note to readers: be sure to read @user2261073's comment and @Jeff's answer concerning a bug in the customizer. It's likely the cause of your problem.

The font file isn't being loaded correctly. Check if the files are in their expected location.

@font-face {
  font-family: 'Glyphicons Halflings';
  src: url('../fonts/glyphicons-halflings-regular.eot');
  src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

As indicated by Daniel, it might also be a mimetype issue. Chrome's dev tools show downloaded fonts in the network tab:

You are passing into the JSONObject constructor an instance of a StringBuilder class.

This is using the JSONObject(Object) constructor, not the JSONObject(String) one.

Your code should be:

JSONObject jsonObj = new JSONObject(jsonString.toString());

Try my solution, I tried it in IE 6, FF2 and Chrome and it renders pixel by pixel in all the three browsers.

If I may summarise what I gathered from this thread:

Unicode 'translates' characters to ordinal numbers (in decimal form).

à -> 224

UTF-8 is an encoding that 'translates' these ordinal numbers (in decimal form) to binary representations.

224 -> 11000011 10100000

Note that we're talking about the binary representation of 224, not its binary form, which is 0b11100000.

First off; best practice would be to get the users Desktop folder with

string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Then you can find all the files with something like

string[] files = Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories);

Note that with the above line you will find all files with a .txt extension in the Desktop folder of the logged in user AND all subfolders.

Then you could copy or move the files by enumerating the above collection like

// For copying...
foreach (string s in files)
{
   File.Copy(s, "C:\newFolder\newFilename.txt");
}

// ... Or for moving
foreach (string s in files)
{
   File.Move(s, "C:\newFolder\newFilename.txt");
}

Please note that you will have to include the filename in your Copy() (or Move()) operation. So you would have to find a way to determine the filename of at least the extension you are dealing with and not name all the files the same like what would happen in the above example.

With that in mind you could also check out the DirectoryInfo and FileInfo classes. These work in similair ways, but you can get information about your path-/filenames, extensions, etc. more easily

Check out these for more info:

I had windows service hosted using OWIN and TopShelf. I was not able to start it. Same error - "Access denied 5"

I ended up giving all the perms to my bin/Debug.

The issue was still not resolved.

So I had a look in the event logs and it turned out that the Microsoft.Owin.Host.HttpListener was not included in the class library containing the OWIN start up class.

So, please make sure you check the event log to identify the root cause before beginning to get into perms, etc.

First, have to check

SELECT * FROM university WHERE course_name LIKE '%&amp%'

Next, have to update

UPDATE university SET course_name = REPLACE(course_name, '&amp', '&') WHERE id = 1

Results: Engineering &amp Technology => Engineering & Technology

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

This is an array of the command line switches pass to the program. E.g. if you start the program with the command "myapp.exe -c -d" then string[] args[] will contain the strings "-c" and "-d".

The code of Ellbar works! You need only add using.

And... the code of Ellbar:

2 - string currentUserId = User.Identity.GetUserId(); ApplicationUser currentUser = db.Users.FirstOrDefault(x => x.Id == currentUserId);

With this code (in currentUser), you work the general data of the connected user, if you want extra data... see this link

This might have been asked before. See Can I add jars to maven 2 build classpath without installing them?

In a nutshell: include your jar as dependency with system scope. This requires specifying the absolute path to the jar.

As stated in the JQuery documentation

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

string tail = test.Substring(test.LastIndexOf('-') + 1);

I'd like to suggest a related solution, which is to pass the @Value-annotated fields as parameters to the constructor, instead of using the ReflectionTestUtils class.

Instead of this:

public class Foo {

    @Value("${foo}")
    private String foo;
}

and

public class FooTest {

    @InjectMocks
    private Foo foo;

    @Before
    public void setUp() {
        ReflectionTestUtils.setField(Foo.class, "foo", "foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Do this:

public class Foo {

    private String foo;

    public Foo(@Value("${foo}") String foo) {
        this.foo = foo;
    }
}

and

public class FooTest {

    private Foo foo;

    @Before
    public void setUp() {
        foo = new Foo("foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Benefits of this approach: 1) we can instantiate the Foo class without a dependency container (it's just a constructor), and 2) we're not coupling our test to our implementation details (reflection ties us to the field name using a string, which could cause a problem if we change the field name).

Old question but if anyone can use a UITextView instead of a UILabel, then it is easy. Standard URLs, phone numbers etc will be automatically detected (and be clickable).

However, if you need custom detection, that is, if you want to be able to call any custom method after a user clicks on a particular word, you need to use NSAttributedStrings with an NSLinkAttributeName attribute that will point to a custom URL scheme(as opposed to having the http url scheme by default). Ray Wenderlich has it covered here

Quoting the code from the aforementioned link:

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"This is an example by @marcelofabri_"];
[attributedString addAttribute:NSLinkAttributeName
                     value:@"username://marcelofabri_"
                     range:[[attributedString string] rangeOfString:@"@marcelofabri_"]];

NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor greenColor],
                             NSUnderlineColorAttributeName: [UIColor lightGrayColor],
                             NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};

// assume that textView is a UITextView previously created (either by code or Interface Builder)
textView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;
textView.delegate = self;

To detect those link clicks, implement this:

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    if ([[URL scheme] isEqualToString:@"username"]) {
        NSString *username = [URL host]; 
        // do something with this username
        // ...
        return NO;
    }
    return YES; // let the system open this URL
}

PS: Make sure your UITextView is selectable.

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

Updated answer for ES6+ is here.

arr = [1, 2, 3]; 

arr.forEach(function(i, idx, array){
   if (idx === array.length - 1){ 
       console.log("Last callback call at index " + idx + " with value " + i ); 
   }
});

would output:

Last callback call at index 2 with value 3

The way this works is testing arr.length against the current index of the array, passed to the callback function.

There is also componentDidUpdate available.

Function signatur:

componentDidUpdate(prevProps, prevState, snapshot)

Use this as an opportunity to operate on the DOM when the component has been updated. Doesn't get called on initial render.

See You Probably Don't Need Derived State Article, which describes Anti-Pattern for both componentDidUpdate and getDerivedStateFromProps. I found it very useful.

Just use matrix:

matrix(vec,nrow = 7,ncol = 7)

One advantage of using matrix rather than simply altering the dimension attribute as Gavin points out, is that you can specify whether the matrix is filled by row or column using the byrow argument in matrix.

So, what's wrong with checking each element iteratively?

function arraysEqual(arr1, arr2) {
    if(arr1.length !== arr2.length)
        return false;
    for(var i = arr1.length; i--;) {
        if(arr1[i] !== arr2[i])
            return false;
    }

    return true;
}

Final class cannot be extended further. If we do not need to make a class inheritable in java,we can use this approach.

If we just need to make particular methods in a class not to be overridden, we just can put final keyword in front of them. There the class is still inheritable.

use of onScroll enters infinite loop. onMomentumScrollEnd or onScrollEndDrag can be used instead

If you are working in windows 7 and you can not run command start with ng

please, update the angular/CLI at once and try to use ng commands

use below comman to update latest CLI

npm install -g @angular/cli@latest

The command setwd("~/") should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/" as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.

As you have tagged the post using RStudio:

• In the bottom right window move the tab over to 'files'.
• Navigate through there to whichever folder you were planning to use as your working directory.
• Under 'more' click 'set as working directory'

You will now have set the folder as your working directory. Use the command getwd() to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd with that string as the argument, so that each time you run the script you use the same directory.

For example at the top of my script I would have:

work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)

Thnaks for answer. I tried it myself too to an Empty Project and - lo behold allmighty creator of heaven and seven seas - it worked. I originally had ListBox inside which was inside of root . For some reason ListBox doesn't like being inside of StackPanel, at all! =)

For my Win7

Paradox was in being java.exe and javaw.exe in System32 folder. Opening that folder I couldn't see them but using search in Start menu I get links to those files, removed them. Next searsh gave me links to files from JAVA_HOME

In Swift 2 and onwards it's possible to add default implementations of a protocol. This creates a new way of optional methods in protocols.

protocol MyProtocol {
    func doSomethingNonOptionalMethod()
    func doSomethingOptionalMethod()
}

extension MyProtocol {
    func doSomethingOptionalMethod(){ 
        // leaving this empty 
    }
}

It's not a really nice way in creating optional protocol methods, but gives you the possibility to use structs in in protocol callbacks.

I wrote a small summary here: https://www.avanderlee.com/swift-2-0/optional-protocol-methods/

yes, but only if main is declared public
