Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):

use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go

Combining the two answers:

First create sql to make all index unusable:

alter session set skip_unusable_indexes = true;
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;

Do import...

select 'alter index ' || u.index_name || ' rebuild online;' from user_indexes u;

left = 37,up = 38, right = 39,down = 40

$(document).keydown(function(e) {
switch(e.which) {
    case 37:
    $( "#prev" ).click();
    break;

    case 38:
    $( "#prev" ).click();
    break;

    case 39:
    $( "#next" ).click();
    break;

    case 40:
    $( "#next" ).click();
    break;

    default: return;
}
e.preventDefault();

});

List_of_list =[([z for z in range(x-2,x+1) if z >= 0],y) for y in range(10) for x in range(10)]

This should do the trick. And the output is this:

[([0], 0), ([0, 1], 0), ([0, 1, 2], 0), ([1, 2, 3], 0), ([2, 3, 4], 0),  ([3, 4, 5], 0), ([4, 5, 6], 0), ([5, 6, 7], 0), ([6, 7, 8], 0), ([7, 8, 9], 0), ([0], 1), ([0, 1], 1), ([0, 1, 2], 1), ([1, 2, 3], 1), ([2, 3, 4], 1), ([3, 4, 5], 1), ([4, 5, 6], 1), ([5, 6, 7], 1), ([6, 7, 8], 1), ([7, 8, 9], 1), ([0], 2), ([0, 1], 2), ([0, 1, 2], 2), ([1, 2, 3], 2), ([2, 3, 4], 2), ([3, 4, 5], 2), ([4, 5, 6], 2), ([5, 6, 7], 2), ([6, 7, 8], 2), ([7, 8, 9], 2), ([0], 3), ([0, 1], 3), ([0, 1, 2], 3), ([1, 2, 3], 3), ([2, 3, 4], 3), ([3, 4, 5], 3), ([4, 5, 6], 3), ([5, 6, 7], 3), ([6, 7, 8], 3), ([7, 8, 9], 3), ([0], 4), ([0, 1], 4), ([0, 1, 2], 4), ([1, 2, 3], 4), ([2, 3, 4], 4), ([3, 4, 5], 4), ([4, 5, 6], 4), ([5, 6, 7], 4), ([6, 7, 8], 4), ([7, 8, 9], 4), ([0], 5), ([0, 1], 5), ([0, 1, 2], 5), ([1, 2, 3], 5), ([2, 3, 4], 5), ([3, 4, 5], 5), ([4, 5, 6], 5), ([5, 6, 7], 5), ([6, 7, 8], 5), ([7, 8, 9], 5), ([0], 6), ([0, 1], 6), ([0, 1, 2], 6), ([1, 2, 3], 6), ([2, 3, 4], 6), ([3, 4, 5], 6), ([4, 5, 6], 6), ([5, 6, 7], 6), ([6, 7, 8], 6), ([7, 8, 9], 6), ([0], 7), ([0, 1], 7), ([0, 1, 2], 7), ([1, 2, 3], 7), ([2, 3, 4], 7), ([3, 4, 5], 7), ([4, 5, 6], 7), ([5, 6, 7], 7), ([6, 7, 8], 7), ([7, 8, 9], 7), ([0], 8), ([0, 1], 8), ([0, 1, 2], 8), ([1, 2, 3], 8), ([2, 3, 4], 8), ([3, 4, 5], 8), ([4, 5, 6], 8), ([5, 6, 7], 8), ([6, 7, 8], 8), ([7, 8, 9], 8), ([0], 9), ([0, 1], 9), ([0, 1, 2], 9), ([1, 2, 3], 9), ([2, 3, 4], 9), ([3, 4, 5], 9), ([4, 5, 6], 9), ([5, 6, 7], 9), ([6, 7, 8], 9), ([7, 8, 9], 9)]    

This is done by list comprehension(which makes looping elements in a list via one line code possible). The logic behind this one-line code is the following:

(1) for x in range(10) and for y in range(10) are employed for two independent loops inside a list

(2) (a list, y) is the general term of the loop, which is why it is placed before two for's in (1)

(3) the length of the list in (2) cannot exceed 3, and the list depends on x, so

[z for z in range(x-2,x+1)] 

is used

(4) because z starts from zero but range(x-2,x+1) starts from -2 which isn't what we want, so a conditional statement if z >= 0 is placed at the end of the list in (2)

[z for z in range(x-2,x+1) if z >= 0] 

Global exclusions look like they're being worked on, but until then...

From the Sonatype maven reference (bottom of the page):

Dependency management in a top-level POM is different from just defining a dependency on a widely shared parent POM. For starters, all dependencies are inherited. If mysql-connector-java were listed as a dependency of the top-level parent project, every single project in the hierarchy would have a reference to this dependency. Instead of adding in unnecessary dependencies, using dependencyManagement allows you to consolidate and centralize the management of dependency versions without adding dependencies which are inherited by all children. In other words, the dependencyManagement element is equivalent to an environment variable which allows you to declare a dependency anywhere below a project without specifying a version number.

As an example:

  <dependencies>
    <dependency>
      <groupId>commons-httpclient</groupId>
      <artifactId>commons-httpclient</artifactId>
      <version>3.1</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>3.0.5.RELEASE</version>
    </dependency>
  </dependencies>
  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
      <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <exclusions>
          <exclusion>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
          </exclusion>
        </exclusions>
      </dependency>
    </dependencies>
  </dependencyManagement>

It doesn't make the code less verbose overall, but it does make it less verbose where it counts. If you still want it less verbose you can follow these tips also from the Sonatype reference.

Does not work, you have to do this:

if ( $("#your_select_id option[value='enter_value_here']").length == 0 ){
  alert("option doesn't exist!");
}

JNDI in layman's terms is basically an Interface for being able to get instances of internal/External resources such as

  javax.sql.DataSource, 
  javax.jms.Connection-Factory,
  javax.jms.QueueConnectionFactory,
  javax.jms.TopicConnectionFactory,
  javax.mail.Session, java.net.URL,
  javax.resource.cci.ConnectionFactory,

or any other type defined by a JCA resource adapter. It provides a syntax in being able to create access whether they are internal or external. i.e (comp/env in this instance means where component/environment, there are lots of other syntax):

jndiContext.lookup("java:comp/env/persistence/customerDB");

Pyexcel works great with both Python2 and Python3 without troubles.

Fast installation with pip:

pip install pyexcel

After that, only 3 lines of code and the job is done:

import pyexcel
data = [['Me', 'You'], ['293', '219'], ['54', '13']]
pyexcel.save_as(array = data, dest_file_name = 'csv_file_name.csv')

Just use for your taste:

_x000D_
// includes (js)_x000D_
_x000D_
if ( blockedTile.includes(118) ){_x000D_
    console.log('Found with "includes"');_x000D_
}_x000D_
_x000D_
// indexOf (js)_x000D_
_x000D_
if ( blockedTile.indexOf(67) !== -1 ){_x000D_
    console.log('Found with "indexOf"');_x000D_
}_x000D_
_x000D_

    console.log('Found with Underscore library "_.indexOf"');_x000D_
}_x000D_
_x000D_
// $.inArray (jQuery library)_x000D_

For anyone that is looking for an easy solution in Visual Studio Community 2019, Fine Code Coverage is simple but it works well.

It cannot give accurate numbers on the precise coverage, but it will tell which lines are being covered with green/red gutters.

You have to loop through the array and printf() each element:

for(int i=0;i<10;++i) {
  printf("%.2f ", foo[i]);
}

printf("\n");

I had the same problem when developing a KNIME Node/plugin in the Eclipse environment. The solution was not only to add the gson.jar as an externar JAR to the build path, it was also required to go to plugin.xml, then the Dependencies tab and add com.google.gson as a required plugin.

    DataSet RsUser = new DataSet();
    RsUser = new DataSet();

       {
        MyConnection.Open();
        MyDataAdapter = new SqlDataAdapter("GetAPPID", MyConnection);
        //'Set the command type as StoredProcedure.
        MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
        RsUser = new DataSet();
        MyDataAdapter.SelectCommand.Parameters.Add(new SqlParameter("@organizationID", 
        SqlDbType.Int));
        MyDataAdapter.SelectCommand.Parameters["@organizationID"].Value = TxtID.Text;
        MyDataAdapter.Fill(RsUser, "GetAPPID");
       }

      if (RsUser.Tables[0].Rows.Count > 0) //data was found
      {
        Session["AppID"] = RsUser.Tables[0].Rows[0]["AppID"].ToString();
       }
     else
       {

       }    
}    

The syntax for an implicit pipe from a shell command into a bash variable is

var=$(command)

or

var=`command`

In your examples, you are piping data to an assignment statement, which does not expect any input.

I had a similar problem with 2D arrays and ended here. I was copying the main array and changing the inner arrays' values and was surprised when the values changed in both copies. Basically both copies were independent but contained references to the same inner arrays and I had to make an array of copies of the inner arrays to get what I wanted.

This is sometimes called a deep copy. The same term "deep copy" can also have a completely different and arguably more complex meaning, which can be confusing, especially to someone not figuring out why their copied arrays don't behave as they should. It probably isn't the OP's problem, but I hope it can still be helpful.

Have a look at this archived question: TortoiseSVN for Mac? at superuser. (Original question was removed, so only archive remains.)

Have a look at this page for more likely up to date alternatives to TortoiseSVN for Mac: Alternative to: TortoiseSVN

FormulaR1C1 has the same behavior as Formula, only using R1C1 style annotation, instead of A1 annotation. In A1 annotation you would use:

Worksheets("Sheet1").Range("A5").Formula = "=A4+A10"

In R1C1 you would use:

Worksheets("Sheet1").Range("A5").FormulaR1C1 = "=R4C1+R10C1"

It doesn't act upon row 1 column 1, it acts upon the targeted cell or range. Column 1 is the same as column A, so R4C1 is the same as A4, R5C2 is B5, and so forth.

The command does not change names, the targeted cell changes. For your R2C3 (also known as C2) example :

Worksheets("Sheet1").Range("C2").FormulaR1C1 = "=your formula here"

What about:

.close-image{
    display:block;
    cursor:pointer;
    z-index:3;
    position:absolute;
    top:0;
    right:0;
}

Is that the desired result?

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

In iOS 10+

Apple enabled the attribute playsinline in all browsers on iOS 10, so this works seamlessly:

<video src="file.mp4" playsinline>

In iOS 8 and iOS 9

Short answer: use iphone-inline-video, it enables inline playback and syncs the audio.

Long answer: You can work around this issue by simulating the playback by skimming the video instead of actually .play()'ing it.

Rather than getting lost amongst the random selection of formulae mentioned here, I suggest you go for the formula recommended by W3C standards.

Here's a straightforward but exact PHP implementation of the WCAG 2.0 SC 1.4.3 relative luminance and contrast ratio formulae. It produces values that are appropriate for evaluating the ratios required for WCAG compliance, as on this page, and as such is suitable and appropriate for any web app. This is trivial to port to other languages.

    $col = trim($col, '#');
    //Convert 3-digit to 6-digit
    if (strlen($col) == 3) {
        $col = $col[0] . $col[0] . $col[1] . $col[1] . $col[2] . $col[2];
    }
    //Convert hex to 0-1 scale
    $components = array(
        'r' => hexdec(substr($col, 0, 2)) / 255,
        'g' => hexdec(substr($col, 2, 2)) / 255,
        'b' => hexdec(substr($col, 4, 2)) / 255
    );

You could go to SmallestDotNet using IE from the server. That will tell you the version and also provide a download link if you're out of date.

The very same. A C string is nothing but an array of characters, so a pointer to a string is a pointer to an array of characters. And a pointer to an array is the very same as a pointer to its first element.

Depending on the data (e.g. tsv extension) it may use tab as separators, so you may try sep = '\t' with read.csv.

Try:

.table thead th{
   vertical-align:middle;
}

add a repository,

sudo apt-add-repository ppa:maarten-fonville/android-studio
sudo apt-get update

Then install using the command below:

sudo apt-get install android-studio

Just use That.Its Easy.

<script language="javascript" type="text/javascript">
     var images = new Array()
     images[0] = "img1.jpg";
     images[1] = "img2.jpg";
     images[2] = "img3.jpg";
     setInterval("changeImage()", 30000);
     var x=0;

     function changeImage()
     {
                document.getElementById("img").src=images[x]
                x++;
                if (images.length == x) 
                {
                    x = 0;
                }
     }

And in Body Write this Code:-

The way to check for null is to check for it:

DataRow[] myResultSet = myDataTable.Select("[COLUMN NAME] is null");

You can use and and or in the Select statement.

From Wikipedia:

According to the 1999 ISO C standard (C99), size_t is an unsigned integer type of at least 16 bit (see sections 7.17 and 7.18.3).

size_tis an unsigned data type defined by several C/C++ standards, e.g. the C99 ISO/IEC 9899 standard, that is defined in stddef.h.1 It can be further imported by inclusion of stdlib.h as this file internally sub includes stddef.h.

This type is used to represent the size of an object. Library functions that take or return sizes expect them to be of type or have the return type of size_t. Further, the most frequently used compiler-based operator sizeof should evaluate to a constant value that is compatible with size_t.

As an implication, size_t is a type guaranteed to hold any array index.

this answer helped me out a lot and pointed me in the right direction but what worked for me, and hopefully others, is:

menuApp.controller("dynamicMenuController", function($scope, $http) {
$scope.appetizers= [];
$http.get('config/menu.json').success(function(data) { 
    console.log("success!");
    $scope.appetizers = data.appetizers;
        console.log(data.appetizers);

There is a JDK socket tutorial here, which covers both the server and client end. That looks exactly like what you want.

(from that tutorial) This sets up to read from an echo server:

    echoSocket = new Socket("taranis", 7);
    out = new PrintWriter(echoSocket.getOutputStream(), true);
    in = new BufferedReader(new InputStreamReader(
                                echoSocket.getInputStream()));

taking a stream of bytes and converts to strings via the reader and using a default encoding (not advisable, normally).

Error handling and closing sockets/streams omitted from the above, but check the tutorial.

class BST:
    def __init__(self, val=None):
        self.left = None

        return "[%s, %s, %s]" % (self.left, str(self.val), self.right)

    def isEmpty(self):
        return self.left == self.right == self.val == None

    def insert(self, val):
        if self.isEmpty():

You can use the text-align-last property

.center-justified {
    text-align: justify;
    text-align-last: center;
}

Here is a compatibility table : https://developer.mozilla.org/en-US/docs/Web/CSS/text-align-last#Browser_compatibility.

Works in all browsers except for Safari (both Mac and iOS), including Internet Explorer.

Also in Internet Explorer, only works with text-align: justify (no other values of text-align) and start and end are not supported.

Here is my solution:

Original Implementation Idea

http://interactivepython.org/runestone/static/pythonds/BasicDS/ImplementinganUnorderedListLinkedLists.html

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

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

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

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

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

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

or the globals function:

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

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

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

If you know the actual type, then just:

SomeType typed = (SomeType)obj;
typed.MyFunction();

If you don't know the actual type, then: not really, no. You would have to instead use one of:

• reflection
• implementing a well-known interface
• dynamic

For example:

// reflection
obj.GetType().GetMethod("MyFunction").Invoke(obj, null);

// interface
IFoo foo = (IFoo)obj; // where SomeType : IFoo and IFoo declares MyFunction
foo.MyFunction();

// dynamic
dynamic d = obj;
d.MyFunction();

You can try this,

$info = pathinfo($_FILES['userFile']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext; 

$target = 'images/'.$newname;
move_uploaded_file( $_FILES['userFile']['tmp_name'], $target);

Very simple example, similar to the one found here:

http://docs.python.org/tutorial/errors.html#defining-clean-up-actions

If you're attempting to catch ALL exceptions, then put all your code within the "try:" statement, in place of 'print "Performing an action which may throw an exception."'.

try:
    print "Performing an action which may throw an exception."
except Exception, error:
    print "An exception was thrown!"
    print str(error)
else:
    print "Everything looks great!"
finally:
    print "Finally is called directly after executing the try statement whether an exception is thrown or not."

In the above example, you'd see output in this order:

1) Performing an action which may throw an exception.

2) Finally is called directly after executing the try statement whether an exception is thrown or not.

3) "An exception was thrown!" or "Everything looks great!" depending on whether an exception was thrown.

Hope this helps!

Let me add my grain of sand here

I personally like adding a constructors as static functions that return an instance of the class (the object). The following code is an example:

 class Person
 {
     private $name;
     private $email;

     public static function withName($name)
     {
         $person = new Person();
         $person->name = $name;

         return $person;
     }

     public static function withEmail($email)
     {
         $person = new Person();
         $person->email = $email;

         return $person;
     }
 }

Note that now you can create instance of the Person class like this:

$person1 = Person::withName('Example');
$person2 = Person::withEmail('yo@mi_email.com');

I took that code from:

http://alfonsojimenez.com/post/30377422731/multiple-constructors-in-php

When you use only integers in a division, you will get integer division. When you use (at least one) double or float, you will get floating point division (and the answer you want to get).

So you can

1. declare one or both of the variables as float/double
2. cast one or both of the variables to float/double.

Do not just cast the result of the integer division to double: the division was already performed as integer division, so the numbers behind the decimal are already lost.

Also you can get the result by using substring and lastIndexOf -

alert("xxx_456".substring("xxx_456".lastIndexOf("_")+1));

If you are using the image as a bullet, you might consider the :before pseudo element.

#footer ul li {
}

#footer ul li:before {
    content: url(/images/arrow.png);
    filter:alpha(opacity=50);
    filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
    opacity:.50;
}

a less expensive and reusable method

function get_post_id_by_name( $post_name, $post_type = 'post' )
{
    $post_ids = get_posts(array
    (
        'post_name'   => $post_name,
        'post_type'   => $post_type,
        'numberposts' => 1,
        'fields' => 'ids'
    ));

    return array_shift( $post_ids );
}

A 'queuecomplete' event has been added. See Issue 317.

I'd like to give a small addition to the existing answers. You get the same "Unclosed Character Literal error", if you give value to a char with incorrect unicode form. Like when you write:

char HI = '\3072';

You have to use the correct form which is:

char HI = '\u3072';

Highest voted answer uses Lodash _.chain function which is considered a bad practice now "Why using _.chain is a mistake."

Here is a fewliner that approaches the problem from functional programming perspective:

import tap from "lodash/fp/tap";
import flow from "lodash/fp/flow";
import groupBy from "lodash/fp/groupBy";

const map = require('lodash/fp/map').convert({ 'cap': false });

const result = flow(
      groupBy('color'),
      map((users, color) => ({color, users})),
      tap(console.log)
    )(input)

Where input is an array that you want to convert.

You can chain class selectors without a space between them:

.a.b {
     color: #666;
}

Note that, if it matters to you, IE6 treats .a.b as .b, so in that browser both div.a.b and div.b will have gray text. See this answer for a comparison between proper browsers and IE6.

Alternative to docker ps --size

As "docker ps --size" produces heavy IO load on host, it is not feasable running such command every minute in a production environment. Therefore we have to do a workaround in order to get desired container size or to be more precise, the size of the RW-Layer with a low impact to systems perfomance.

This approach gathers the "device name" of every container and then checks size of it using "df" command. Those "device names" are thin provisioned volumes that a mounted to / on each container. One problem still persists as this observed size also implies all the readonly-layers of underlying image. In order to address this we can simple check size of used container image and substract it from size of a device/thin_volume.

One should note that every image layer is realized as a kind of a lvm snapshot when using device mapper. Unfortunately I wasn't able to get my rhel system to print out those snapshots/layers. Otherwise we could simply collect sizes of "latest" snapshots. Would be great if someone could make things clear. However...

After some tests, it seems that creation of a container always adds an overhead of approx. 40MiB (tested with containers based on Image "httpd:2.4.46-alpine"):

1. docker run -d --name apache httpd:2.4.46-alpine // now get device name from docker inspect and look it up using df
2. df -T -> 90MB whereas "Virtual Size" from "docker ps --size" states 50MB and a very small payload of 2Bytes -> mysterious overhead 40MB
3. curl/download of a 100MB file within container
4. df -T -> 190MB whereas "Virtual Size" from "docker ps --size" states 150MB and payload of 100MB -> overhead 40MB

Following shell prints results (in bytes) that match results from "docker ps --size" (but keep in mind mentioned overhead of 40MB)

for c in  $(docker ps -q); do \
container_name=$(docker inspect -f "{{.Name}}" ${c} | sed 's/^\///g' ); \
device_n=$(docker inspect -f "{{.GraphDriver.Data.DeviceName}}" ${c} | sed 's/.*-//g'); \
device_size_kib=$(df -T | grep ${device_n} | awk '{print $4}'); \
device_size_byte=$((1024 * ${device_size_kib})); \
image_sha=$(docker inspect -f "{{.Image}}" ${c} | sed 's/.*://g' ); \
image_size_byte=$(docker image inspect -f "{{.Size}}" ${image_sha}); \
container_size_byte=$((${device_size_byte} - ${image_size_byte})); \
\
echo my_node_dm_device_size_bytes\{cname=\"${container_name}\"\} ${device_size_byte}; \
echo my_node_dm_container_size_bytes\{cname=\"${container_name}\"\} ${container_size_byte}; \
echo my_node_dm_image_size_bytes\{cname=\"${container_name}\"\} ${image_size_byte}; \
done

There is an easy way, based on the hours between the two days BUT with the end date truncated.

SELECT CAST(DATEDIFF(hour,Birthdate,CAST(GETDATE() as Date))/8766.0 as INT) AS Age FROM <YourTable>

This one has proven to be extremely accurate and reliable. If it weren't for the inner CAST on the GETDATE() it might flip the birthday a few hours before midnight but, with the CAST, it is dead on with the age changing over at exactly midnight.

Seems like this is ought to be the approved answer...

Intl.NumberFormat('en-US').format(count)

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat

Without lambda:

def sec_elem(s):
    return s[1]

sorted(data, key=sec_elem)

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

Have you tried getFilesDir().getAbsolutePath()?

Seems you fixed your problem by initializing the File object with a full path. I believe this would also do the trick.

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

I've written a simple recursive function that generates file names like Windows does, by appending a sequence number prior to the file extension.

Given a desired file path of C:\MyDir\MyFile.txt, and the file already exists, it returns a final file path of C:\MyDir\MyFile_1.txt.

It is called like this:

var desiredPath = @"C:\MyDir\MyFile.txt";
var finalPath = UniqueFileName(desiredPath);

private static string UniqueFileName(string path, int count = 0)
{
    if (count == 0)
    {
        if (!File.Exists(path))
        {
            return path;
        }
    }
    else
    {
        var candidatePath = string.Format(
            @"{0}\{1}_{2}{3}",
            Path.GetDirectoryName(path),
            Path.GetFileNameWithoutExtension(path),
            count,
            Path.GetExtension(path));

        if (!File.Exists(candidatePath))
        {
            return candidatePath;
        }
    }

    count++;
    return UniqueFileName(path, count);
}

It's resolved the problem now.

Here's a custom hook that I use which I believe is more intuitive than using usePrevious.

import { useRef, useEffect } from 'react'

// useTransition :: Array a => (a -> Void, a) -> Void
//                              |_______|  |
//                                  |      |
//                              callback  deps
//
// The useTransition hook is similar to the useEffect hook. It requires
// a callback function and an array of dependencies. Unlike the useEffect
// hook, the callback function is only called when the dependencies change.
// Hence, it's not called when the component mounts because there is no change
// in the dependencies. The callback function is supplied the previous array of
// dependencies which it can use to perform transition-based effects.
const useTransition = (callback, deps) => {
  const func = useRef(null)

  useEffect(() => {
    func.current = callback
  }, [callback])

  const args = useRef(null)

  useEffect(() => {
    if (args.current !== null) func.current(...args.current)
    args.current = deps
  }, deps)
}

You'd use useTransition as follows.

useTransition((prevRate, prevSendAmount, prevReceiveAmount) => {
  if (sendAmount !== prevSendAmount || rate !== prevRate && sendAmount > 0) {
    const newReceiveAmount = sendAmount * rate
    // do something
  } else {
    const newSendAmount = receiveAmount / rate
    // do something
  }
}, [rate, sendAmount, receiveAmount])

Hope that helps.

MSDN has provided easy way to debug the stored procedure. Please check this link-
How to: Debug Stored Procedures

Alright, it's the usual "super() cannot be used with an old-style class".

However, the important point is that the correct test for "is this a new-style instance (i.e. object)?" is

>>> class OldStyle: pass
>>> instance = OldStyle()
>>> issubclass(instance.__class__, object)
False

and not (as in the question):

>>> isinstance(instance, object)
True

For classes, the correct "is this a new-style class" test is:

>>> issubclass(OldStyle, object)  # OldStyle is not a new-style class
False
>>> issubclass(int, object)  # int is a new-style class
True

The crucial point is that with old-style classes, the class of an instance and its type are distinct. Here, OldStyle().__class__ is OldStyle, which does not inherit from object, while type(OldStyle()) is the instance type, which does inherit from object. Basically, an old-style class just creates objects of type instance (whereas a new-style class creates objects whose type is the class itself). This is probably why the instance OldStyle() is an object: its type() inherits from object (the fact that its class does not inherit from object does not count: old-style classes merely construct new objects of type instance). Partial reference: https://stackoverflow.com/a/9699961/42973.

PS: The difference between a new-style class and an old-style one can also be seen with:

>>> type(OldStyle)  # OldStyle creates objects but is not itself a type
classobj
>>> isinstance(OldStyle, type)
False
>>> type(int)  # A new-style class is a type
type

(old-style classes are not types, so they cannot be the type of their instances).

You need to call format() function to get the formatted value

$scope.SearchDate = moment(new Date()).format("DD/MM/YYYY")
//or $scope.SearchDate = moment().format("DD/MM/YYYY")

The syntax you have used is used to parse a given string to date object by using the specified formate

Isn't your issue that you're setting the webkitAnimationName back to nothing so that's resetting the CSS for your object back to it's default state. Won't it stay where it ended up if you just remove the setTimeout function that's resetting the state?

As this is specifically tagged for jQuery -

$("#myElement")[0].getBoundingClientRect();

or

$("#myElement").get(0).getBoundingClientRect();

(These are functionally identical, in some older browsers .get() was slightly faster)

Note that if you try to get the values via jQuery calls then it will not take into account any css transform values, which can give unexpected results...

Note 2: In jQuery 3.0 it has changed to using the proper getBoundingClientRect() calls for its own dimension calls (see the jQuery Core 3.0 Upgrade Guide) - which means that the other jQuery answers will finally always be correct - but only when using the new jQuery version - hence why it's called a breaking change...

In other words on keeping this brief: in case of root, location argument specified is part of filesystem's path and URI . On the other hand — for alias directive argument of location statement is part of URI only

So, alias is a different name that maps certain URI to certain path in the filesystem, whereas root appends location argument to the root path given as argument to root directive.

url isn't an object on the Marker class. But there's nothing stopping you adding that as a property to that class. I'm guessing whatever example you were looking at did that too. Do you want a different URL for each marker? What happens when you do:

for (var i = 0; i < locations.length; i++) 
{
    var flag = new google.maps.MarkerImage('markers/' + (i + 1) + '.png',
      new google.maps.Size(17, 19),
      new google.maps.Point(0,0),
      new google.maps.Point(0, 19));
    var place = locations[i];
    var myLatLng = new google.maps.LatLng(place[1], place[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        icon: flag,
        shape: shape,
        title: place[0],
        zIndex: place[3],
        url: "/your/url/"
    });

    google.maps.event.addListener(marker, 'click', function() {
        window.location.href = this.url;
    });
}

Try using "nlargest" on the groupby object. The advantage of using nlargest is that it returns the index of the rows where "the nlargest item(s)" were fetched from. Note: we slice the second(1) element of our index since our index in this case consist of tuples(eg.(s1, 0)).

df = pd.DataFrame({
'sp' : ['MM1', 'MM1', 'MM1', 'MM2', 'MM2', 'MM2', 'MM4', 'MM4','MM4'],
'mt' : ['S1', 'S1', 'S3', 'S3', 'S4', 'S4', 'S2', 'S2', 'S2'],
'val' : ['a', 'n', 'cb', 'mk', 'bg', 'dgb', 'rd', 'cb', 'uyi'],
'count' : [3,2,5,8,10,1,2,2,7]
})

d = df.groupby('mt')['count'].nlargest(1) # pass 1 since we want the max

df.iloc[[i[1] for i in d.index], :] # pass the index of d as list comprehension

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

Streams are good for dealing with large amounts of data. When it's impractical to load all the data into memory at the same time, you can open it as a stream and work with small chunks of it.

You have strange expectations. If you gave the chain of arguments that led you to them, we might spot the flaw in them. As it is, I can only give a short primer on generics, hoping to touch on the points you might have misunderstood.

ArrayList<? extends Object> is an ArrayList whose type parameter is known to be Object or a subtype thereof. (Yes, extends in type bounds has a meaning other than direct subclass). Since only reference types can be type parameters, this is actually equivalent to ArrayList<?>.

That is, you can put an ArrayList<String> into a variable declared with ArrayList<?>. That's why a1.add(3) is a compile time error. a1's declared type permits a1 to be an ArrayList<String>, to which no Integer can be added.

Clearly, an ArrayList<?> is not very useful, as you can only insert null into it. That might be why the Java Spec forbids it:

It is a compile-time error if any of the type arguments used in a class instance creation expression are wildcard type arguments

ArrayList<ArrayList<?>> in contrast is a functional data type. You can add all kinds of ArrayLists into it, and retrieve them. And since ArrayList<?> only contains but is not a wildcard type, the above rule does not apply.

Why is the WebSockets protocol better?

I don't think we can compare them side by side like who is better. That won't be a fair comparison simply because they are solving two different problems. Their requirements are different. It will be like comparing apples to oranges. They are different.

HTTP is a request-response protocol. The client (browser) wants something, the server gives it. That is. If the data client wants is big, the server might send streaming data to void unwanted buffer problems. Here the main requirement or problem is how to make the request from clients and how to response the resources(hypertext) they request. That is where HTTP shine.

In HTTP, only client requests. The server only responds.

WebSocket is not a request-response protocol where only the client can request. It is a socket(very similar to TCP socket). Mean once the connection is open, either side can send data until the underlining TCP connection is closed. It is just like a normal socket. The only difference with TCP socket is WebSocket can be used on the web. On the web, we have many restrictions on a normal socket. Most firewalls will block other ports than 80 and 433 that HTTP used. Proxies and intermediaries will be problematic as well. So to make the protocol easier to deploy to existing infrastructures WebSocket use HTTP handshake to upgrade. That means when the first time connection is going to open, the client sent an HTTP request to tell the server saying "That is not HTTP request, please upgrade to WebSocket protocol".

Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw==
Sec-WebSocket-Protocol: chat, superchat
Sec-WebSocket-Version: 13

Once the server understands the request and upgraded to WebSocket protocol, none of the HTTP protocols applied anymore.

So my answer is Neither one is better than each other. They are completely different.

Why was it implemented instead of updating the HTTP protocol?

Well, we can make everything under the name called HTTP as well. But shall we? If they are two different things, I will prefer two different names. So do Hickson and Michael Carter .

First, modify your search filter to only look for users and not contacts:

(&(objectCategory=person)(objectClass=user)(sAMAccountName=BTYNDALL))

You can enumerate all of the domains of a forest by connecting to the configuration partition and enumerating all the entries in the partitions container. Sorry I don't have any C# code right now but here is some vbscript code I've used in the past:

Set objRootDSE = GetObject("LDAP://RootDSE")
AdComm.Properties("Sort on") = "name"
AdComm.CommandText = "<LDAP://cn=Partitions," & _
    objRootDSE.Get("ConfigurationNamingContext") & ">;" & _
        "(&(objectcategory=crossRef)(systemFlags=3));" & _
            "name,nCName,dnsRoot;onelevel"
set AdRs = AdComm.Execute

From that you can retrieve the name and dnsRoot of each partition:

AdRs.MoveFirst
With AdRs
  While Not .EOF
    dnsRoot = .Fields("dnsRoot")

    Set objOption = Document.createElement("OPTION")
    objOption.Text = dnsRoot(0)
    objOption.Value = "LDAP://" & dnsRoot(0) & "/" & .Fields("nCName").Value
    Domain.Add(objOption)
    .MoveNext 
  Wend 
End With

Just sort by whatever (mpg for example, question is not clear on this)

mt <- mtcars[order(mtcars$mpg), ]

then use the by function to get the top n rows in each group

d <- by(mt, mt["cyl"], head, n=4)

If you want the result to be a data.frame:

Reduce(rbind, d)

Edit: Handling ties is more difficult, but if all ties are desired:

by(mt, mt["cyl"], function(x) x[rank(x$mpg) %in% sort(unique(rank(x$mpg)))[1:4], ])

Another approach is to break ties based on some other information, e.g.,

mt <- mtcars[order(mtcars$mpg, mtcars$hp), ]
by(mt, mt["cyl"], head, n=4)

If you'd like to send the data to a view pass the following in.

    server.get('/usersList', function(req, res) {
        User.find({}, function(err, users) {
           res.render('/usersList', {users: users});
        });
    });

Inside your view you can loop through the data using the variable users

There are a few ways to handle events with HTML/DOM. There's no real right or wrong way but different ways are useful in different situations.

1: There's defining it in the HTML:

<input id="clickMe" type="button" value="clickme" onclick="doFunction();" />

2: There's adding it to the DOM property for the event in Javascript:

//- Using a function pointer:
document.getElementById("clickMe").onclick = doFunction;

//- Using an anonymous function:
document.getElementById("clickMe").onclick = function () { alert('hello!'); };

3: And there's attaching a function to the event handler using Javascript:

var el = document.getElementById("clickMe");
if (el.addEventListener)
    el.addEventListener("click", doFunction, false);
else if (el.attachEvent)
    el.attachEvent('onclick', doFunction);

Both the second and third methods allow for inline/anonymous functions and both must be declared after the element has been parsed from the document. The first method isn't valid XHTML because the onclick attribute isn't in the XHTML specification.

The 1st and 2nd methods are mutually exclusive, meaning using one (the 2nd) will override the other (the 1st). The 3rd method will allow you to attach as many functions as you like to the same event handler, even if the 1st or 2nd method has been used too.

Most likely, the problem lies somewhere in your CapacityChart() function. After visiting your link and running your script, the CapacityChart() function runs and the two popups are opened (one is closed as per the script). Where you have the following line:

CapacityWindow.document.write(s);

Try the following instead:

CapacityWindow.document.open("text/html");
CapacityWindow.document.write(s);
CapacityWindow.document.close();

EDIT
When I saw your code I thought you were writing it specifically for IE. As others have mentioned you will need to replace references to document.all with document.getElementById. However, you will still have the task of fixing the script after this so I would recommend getting it working in at least IE first as any mistakes you make changing the code to work cross browser could cause even more confusion. Once it's working in IE it will be easier to tell if it's working in other browsers whilst you're updating the code.

firebaseFirestore.collection("...").addSnapshotListener(new EventListener<QuerySnapshot>() {
        @Override
        public void onEvent(QuerySnapshot documentSnapshots, FirebaseFirestoreException e) {

            int Counter = documentSnapshots.size();

        }
    });

OK I found it.

=LARGE($E$4:$E$9;A12)

=large(array, k)

Array Required. The array or range of data for which you want to determine the k-th largest value.

K Required. The position (from the largest) in the array or cell range of data to return.

Most easiest way is to use ViewTreeObserver, if you directly use .height or .width you get values as 0, due to views are not have size until they draw on our screen. Following example will show how to use ViewTreeObserver

ViewTreeObserver viewTreeObserver = YOUR_VIEW_TO_MEASURE.getViewTreeObserver();
        if (viewTreeObserver.isAlive()) {
            viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {

                    YOUR_VIEW_TO_MEASURE.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    int viewHeight = YOUR_VIEW_TO_MEASURE.getHeight();
                    int viewWeight = YOUR_VIEW_TO_MEASURE.getWidth();

                }
            });
        }

if you need to use this on method, use like this and to save the values you can use globle variables.

try the following code :

In your controller :

 function myCtrl ($scope) {
      $scope.units = [
         {'id': 10, 'label': 'test1'},
         {'id': 27, 'label': 'test2'},
         {'id': 39, 'label': 'test3'},
      ];

   $scope.data= $scope.units[0]; // Set by default the value "test1"
 };

In your page :

 <select ng-model="data" ng-options="opt as opt.label for opt in units ">
                </select>

Working Fiddle

Make sure your database myAttribute field contains null instead of zero.

The :javascript filter was removed in version 7.0

The docs says you should use a script tag now, followed by a . char and no preceding space.

Example:

script.
  if (usingJade)
    console.log('you are awesome')
  else
    console.log('use jade')

will be compiled to

<script>
  if (usingJade)
    console.log('you are awesome')
  else
    console.log('use jade')
</script>

Uncaught exception messages go to STDERR, so instead of implementing your logging in Python itself you could send STDERR to a file using whatever shell you're using to run your Python script. In a Bash script, you can do this with output redirection, as described in the BASH guide.

Examples

Append errors to file, other output to the terminal:

./test.py 2>> mylog.log

Overwrite file with interleaved STDOUT and STDERR output:

./test.py &> mylog.log

Yes, this is new in PHP 5.3. It returns either the value of the test expression if it is evaluated as TRUE, or the alternative value if it is evaluated as FALSE.

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

You can overwrite a CSS class by making it "more specific".

You go up the HTML tree, and specify parent elements:

div.sidebar { ... } is more specific than .sidebar { ... }

You can go all the way up to BODY if you need to:

body .sidebar { ... } will override virtually anything.

See this handy guide: http://css-tricks.com/855-specifics-on-css-specificity/

In Teradata perspective :

From a result set point of view, it does not matter if you use DISTINCT or GROUP BY in Teradata. The answer set will be the same.

From a performance point of view, it is not the same.

To understand what impacts performance, you need to know what happens on Teradata when executing a statement with DISTINCT or GROUP BY.

In the case of DISTINCT, the rows are redistributed immediately without any preaggregation taking place, while in the case of GROUP BY, in a first step a preaggregation is done and only then are the unique values redistributed across the AMPs.

Don’t think now that GROUP BY is always better from a performance point of view. When you have many different values, the preaggregation step of GROUP BY is not very efficient. Teradata has to sort the data to remove duplicates. In this case, it may be better to the redistribution first, i.e. use the DISTINCT statement. Only if there are many duplicate values, the GROUP BY statement is probably the better choice as only once the deduplication step takes place, after redistribution.

In short, DISTINCT vs. GROUP BY in Teradata means:

GROUP BY -> for many duplicates DISTINCT -> no or a few duplicates only . At times, when using DISTINCT, you run out of spool space on an AMP. The reason is that redistribution takes place immediately, and skewing could cause AMPs to run out of space.

If this happens, you have probably a better chance with GROUP BY, as duplicates are already removed in a first step, and less data is moved across the AMPs.

Am using angular 5 and for an ngif to work for me that is in a ngfor, I had to use animateChild and in the user-detail component I used the *ngIf="user.expanded" to show hide user and it worked for entering a leaving

 <div *ngFor="let user of users" @flyInParent>
  <ly-user-detail [user]= "user" @flyIn></user-detail>
</div>

//the animation file


export const FLIP_TRANSITION = [ 
trigger('flyInParent', [
    transition(':enter, :leave', [
      query('@*', animateChild())
    ])
  ]),
  trigger('flyIn', [
    state('void', style({width: '100%', height: '100%'})),
    state('*', style({width: '100%', height: '100%'})),
    transition(':enter', [
      style({
        transform: 'translateY(100%)',
        position: 'fixed'
      }),
      animate('0.5s cubic-bezier(0.35, 0, 0.25, 1)', style({transform: 'translateY(0%)'}))
    ]),
    transition(':leave', [
      style({
        transform: 'translateY(0%)',
        position: 'fixed'
      }),
      animate('0.5s cubic-bezier(0.35, 0, 0.25, 1)', style({transform: 'translateY(100%)'}))
    ])
  ])
];

An Integer is pretty much just a wrapper for the primitive type int. It allows you to use all the functions of the Integer class to make life a bit easier for you.

If you're new to Java, something you should learn to appreciate is the Java documentation. For example, anything you want to know about the Integer Class is documented in detail.

This is straight out of the documentation for the Integer class:

The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

Had same issue when I had to develop a fixed length field format.

Usually we do not use line separator for binary files but For some reason our customer wished to add a line break as separator between records. They set

< record_delimiter value="\n"/ >

but this didn't work as records got two additional characters:
< record1 > \n < record2 > \n.... and so on.

Did following change and it just worked.

< record_delimiter value="\n"/> => < record_delimiter value="&#xA;"/ >

After unmarshaling Java interprets as new line character.

I think this say it all:

this alternative syntax is excellent for improving legibility (for both PHP and HTML!) in situations where you have a mix of them.

http://ca3.php.net/manual/en/control-structures.alternative-syntax.php

When mixing HTML an PHP the alternative sytnax is much easier to read. In normal PHP documents the traditional syntax should be used.

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

Alternatively...

var rowCount = $('table#myTable tr:last').index() + 1;

jsFiddle DEMO

This will ensure that any nested table-rows are not also counted.

ugh don't use eval for anything. Well, there are certain things, but they're extremely rare. Rather, you would do this:

document.getElementById("test").onchange()

Probably the best way is to use Guava

List<String> list = new ArrayList<String>();
list.add("How are you");
list.add("How you doing");
list.add("Joe");
list.add("Mike");
    
Collection<String> filtered = Collections2.filter(list,
    Predicates.containsPattern("How"));
print(filtered);

prints

How are you
How you doing

In case you want to get the filtered collection as a list, you can use this (also from Guava):

List<String> filteredList = Lists.newArrayList(Collections2.filter(
    list, Predicates.containsPattern("How")));

You can also define a scale transformation, with CSS like so:

.larger-icon {
 transform:scale(2);
}

Maybe useful for anyone else running into this issue: When setting the port on the properties:

props.put("mail.smtp.port", smtpPort);

..make sure to use a string object. Using a numeric (ie Long) object will cause this statement to seemingly have no effect.

Visual Studio Code detects the current indentation per default and uses this - ignoring the .editorconfig

Set also "editor.detectIndentation" to false

You can always wrap Double.parseDouble() in a try catch block.

try
{
  Double.parseDouble(number);
}
catch(NumberFormatException e)
{
  //not a double
}

I was able to solve "ORA-00604: error" by Droping with purge.

FindControl does not search within nested controls recursively. It does only find controls that's NamigContainer is the Control on that you are calling FindControl.

Theres a reason that ASP.Net does not look into your nested controls recursively by default:

• Performance
• Avoiding errors
• Reusability

Consider you want to encapsulate your GridViews, Formviews, UserControls etc. inside of other UserControls for reusability reasons. If you would have implemented all logic in your page and accessed these controls with recursive loops, it'll very difficult to refactor that. If you have implemented your logic and access methods via the event-handlers(f.e. RowDataBound of GridView), it'll be much simpler and less error-prone.

Your login root should be /usr/local/directadmin/conf/mysql.conf. Then try following

UPDATE mysql.user SET password=PASSWORD('$w0rdf1sh') WHERE user='tate256' AND Host='10.10.2.30';
FLUSH PRIVILEGES;

Host is your mysql host.

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.

But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.

It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.

I'm not sure what you're doing, but this will go from JSON to CSV using JavaScript. This is using the open source JSON library, so just download JSON.js into the same folder you saved the code below into, and it will parse the static JSON value in json3 into CSV and prompt you to download/open in Excel.

I had the same problem using the com.xxx.service.model package.

To fix it, I first made a backup of the code changes in the model package. Then deleted model package and synchronized with the repository. It will show incoming the entire folder/package. Then updated my code.

Finally, paste the old code commit to the SVN Repository. It works fine.

You need to use ECHO. Also, put the quotes around the entire file path if it contains spaces.

One other note, use > to overwrite a file if it exists or create if it does not exist. Use >> to append to an existing file or create if it does not exist.

Overwrite the file with a blank line:

ECHO.>"C:\My folder\Myfile.log"

Append a blank line to a file:

ECHO.>>"C:\My folder\Myfile.log"

Append text to a file:

ECHO Some text>>"C:\My folder\Myfile.log"

Append a variable to a file:

ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"

declare @temp as varchar
  set @temp='Measure'
  if(@temp = 'Measure')
Select Measure from Measuretable
else
Select OtherMeasure from Measuretable

In my system (Ubuntu 12.04) I found RESET QUERY CACHE and even restarting mysql server not enough. This was due to memory disc caching.
After each query, I clean the disc cache in the terminal:

sync && echo 3 | sudo tee /proc/sys/vm/drop_caches

and then reset the query cache in mysql client:

RESET QUERY CACHE;

   try{

    BufferedReader br = new BufferedReader(new FileReader("textfile.txt"));
    String strLine;
    //Read File Line By Line
    while ((strLine = br.readLine()) != null)   {
      // Print the content on the console
      System.out.println (strLine);
    }
    //Close the input stream
    in.close();
    }catch (Exception e){//Catch exception if any
      System.err.println("Error: " + e.getMessage());
    }finally{
     in.close();
    }

This will read line by line,

If your no. are saperated by newline char. then in place of

 System.out.println (strLine);

You can have

try{
int i = Integer.parseInt(strLine);
}catch(NumberFormatException npe){
//do something
}  

If it is separated by spaces then

try{
    String noInStringArr[] = strLine.split(" ");
//then you can parse it to Int as above
    }catch(NumberFormatException npe){
    //do something
    }  

The default to open/add rows to a table is Edit Top 200 Rows. If you have more than 200 rows, like me now, then you need to change the default setting. Here's what I did to change the edit default to 300:

1. Go to Tools in top nav
2. Select options, then SQL Service Object Explorer (on left)
3. On right side of panel, click into the field that contains 200 and change to 300 (or whatever number you wish)
4. Click OK and voila, you're all set!

var percent = Math.floor(100 * number1 / number2 - 100) + ' %';

If you are using Lodash library you can use the below function as well. It should remove duplicate objects.

var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];
_.uniqWith(objects, _.isEqual);

I found both, x64 and x86 version 6.12.0002.633 here:

1. Javascript

   function validateDate(date) {
       try {
           new Date(date).toISOString();
           return true;
       } catch (e) { 
           return false; 
       }
   }
   

2. JQuery

   $.fn.validateDate = function() {
       try {
           new Date($(this[0]).val()).toISOString();
           return true;
       } catch (e) { 
           return false; 
       }
   }
   

returns true for a valid date string.

Five ways, 4 for bash and 1 addition for zsh:

• type foobar &> /dev/null
• hash foobar &> /dev/null
• command -v foobar &> /dev/null
• which foobar &> /dev/null
• (( $+commands[foobar] )) (zsh only)

You can put any of them to your if clause. According to my tests (https://www.topbug.net/blog/2016/10/11/speed-test-check-the-existence-of-a-command-in-bash-and-zsh/), the 1st and 3rd method are recommended in bash and the 5th method is recommended in zsh in terms of speed.

insert into AGREGADORES_AGREGADORES (IDAGREGADOR,NOMBRE,URL)
values (2,'Netvibes',
'http://www.netvibes.com/subscribe.php?type=rss' || chr(38) || 'amp;url=');

Save a flag if you are paused or resumed. If you are resumed it means you are in the foreground

boolean  isResumed = false;

@Override
public void onPause() {
  super.onPause();    
  isResumed = false;
}

@Override
public void onResume() {
  super.onResume();    
  isResumed = true;
}

private void finishIfForeground() {
  if (isResumed) {
    finish();
  }
}

In a batch file (Windows 7 and above) I found this method most reliable

Call :logging >"C:\Temp\NAME_Your_Log_File.txt" 2>&1
:logging
TITLE "Logging Commands"
ECHO "Read this output in your log file"
ECHO ..
Prompt $_
COLOR 0F

Obviously, use whatever commands you want and the output will be directed to the text file. Using this method is reliable HOWEVER there is NO output on the screen.

Sending data from formfields back to the server (php) is usualy done by the POST method which can be found back in the superglobal array $_POST inside PHP. There is no need to transform it to JSON before you send it to the server. Little example:

<?php

if($_SERVER['REQUEST_METHOD'] == 'POST')
{
    echo '<pre>';
    print_r($_POST);
}
?>
<form action="" method="post">
<input type="text" name="email" value="[email protected]" />
<button type="submit">Send!</button>

With AJAX you are able to do exactly the same thing, only without page refresh.

I’ve run into this problem too. Another solution is to toggle the SELinux boolean value for httpd network connect to on (Nginx uses the httpd label).

setsebool httpd_can_network_connect on

To make the change persist use the -P flag.

setsebool httpd_can_network_connect on -P

You can see a list of all available SELinux booleans for httpd using

getsebool -a | grep httpd

The example Java data structure in the original question does not match the description of the JSON structure in the comment.

The JSON is described as

"an array of {object with an array of {object}}".

In terms of the types described in the question, the JSON translated into a Java data structure that would match the JSON structure for easy deserialization with Gson is

"an array of {TypeDTO object with an array of {ItemDTO object}}".

But the Java data structure provided in the question is not this. Instead it's

"an array of {TypeDTO object with an array of an array of {ItemDTO object}}".

A two-dimensional array != a single-dimensional array.

This first example demonstrates using Gson to simply deserialize and serialize a JSON structure that is "an array of {object with an array of {object}}".

input.json Contents:

[
  {
    "id":1,
    "name":"name1",
    "items":
    [
      {"id":2,"name":"name2","valid":true},
      {"id":3,"name":"name3","valid":false},
      {"id":4,"name":"name4","valid":true}
    ]
  },
  {
    "id":5,
    "name":"name5",
    "items":
    [
      {"id":6,"name":"name6","valid":true},
      {"id":7,"name":"name7","valid":false}
    ]
  },
  {
    "id":8,
    "name":"name8",
    "items":
    [
      {"id":9,"name":"name9","valid":true},
      {"id":10,"name":"name10","valid":false},
      {"id":11,"name":"name11","valid":false},
      {"id":12,"name":"name12","valid":true}
    ]
  }
]

Foo.java:

import java.io.FileReader;
import java.util.ArrayList;

import com.google.gson.Gson;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);
    System.out.println(gson.toJson(myTypes));
  }
}

class TypeDTO
{
  int id;
  String name;
  ArrayList<ItemDTO> items;
}

class ItemDTO
{
  int id;
  String name;
  Boolean valid;
}

This second example uses instead a JSON structure that is actually "an array of {TypeDTO object with an array of an array of {ItemDTO object}}" to match the originally provided Java data structure.

input.json Contents:

[
  {
    "id":1,
    "name":"name1",
    "items":
    [
      [
        {"id":2,"name":"name2","valid":true},
        {"id":3,"name":"name3","valid":false}
      ],
      [
        {"id":4,"name":"name4","valid":true}
      ]
    ]
  },
  {
    "id":5,
    "name":"name5",
    "items":
    [
      [
        {"id":6,"name":"name6","valid":true}
      ],
      [
        {"id":7,"name":"name7","valid":false}
      ]
    ]
  },
  {
    "id":8,
    "name":"name8",
    "items":
    [
      [
        {"id":9,"name":"name9","valid":true},
        {"id":10,"name":"name10","valid":false}
      ],
      [
        {"id":11,"name":"name11","valid":false},
        {"id":12,"name":"name12","valid":true}
      ]
    ]
  }
]

Foo.java:

import java.io.FileReader;
import java.util.ArrayList;

import com.google.gson.Gson;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);
    System.out.println(gson.toJson(myTypes));
  }
}

class TypeDTO
{
  int id;
  String name;
  ArrayList<ItemDTO> items[];
}

class ItemDTO
{
  int id;
  String name;
  Boolean valid;
}

Regarding the remaining two questions:

is Gson extremely fast?

Not compared to other deserialization/serialization APIs. Gson has traditionally been amongst the slowest. The current and next releases of Gson reportedly include significant performance improvements, though I haven't looked for the latest performance test data to support those claims.

That said, if Gson is fast enough for your needs, then since it makes JSON deserialization so easy, it probably makes sense to use it. If better performance is required, then Jackson might be a better choice to use. It offers much (maybe even all) of the conveniences of Gson.

Or am I better to stick with what I've got working already?

I wouldn't. I would most always rather have one simple line of code like

TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);

...to easily deserialize into a complex data structure, than the thirty lines of code that would otherwise be needed to map the pieces together one component at a time.

you have an type error in example of code. You forget curlybracket after success

$.ajax({
 type: "POST",
 url: '@Url.Action("Search","Controller")',
 data: "{queryString:'" + searchVal + "'}",
 contentType: "application/json; charset=utf-8",
 dataType: "html",
 success: function (data) {
     alert("here" + data.d.toString());
 }
})

;

It means that the http server at cw.na1.hgncloud.com send some http headers to tell web browsers like Chrome to allow iframe loading of that page (https://cw.na1.hgncloud.com/crossmatch/) only from a page hosted on the same domain (cw.na1.hgncloud.com) :

Note that if you are using Java 5 or newer, you should use StringBuilder instead of StringBuffer. From the API documentation:

As of release JDK 5, this class has been supplemented with an equivalent class designed for use by a single thread, StringBuilder. The StringBuilder class should generally be used in preference to this one, as it supports all of the same operations but it is faster, as it performs no synchronization.

In practice, you will almost never use this from multiple threads at the same time, so the synchronization that StringBuffer does is almost always unnecessary overhead.

You can use twiny to create 2 x-axis scales. For Example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

a = np.cos(2*np.pi*np.linspace(0, 1, 60.))

ax1.plot(range(60), a)
ax2.plot(range(100), np.ones(100)) # Create a dummy plot
ax2.cla()
plt.show()

Ref: http://matplotlib.sourceforge.net/faq/howto_faq.html#multiple-y-axis-scales

Output:

var just tells the compiler to infer the type you wanted at compile time...it cannot infer from null (though there are cases it could).

So, no you are not allowed to do this.

When you say "some empty value"...if you mean:

var s = string.Empty;
//
var s = "";

Then yes, you may do that, but not null.

SELECT t1.ks, t1.[# Tasks], COALESCE(t2.[# Late], 0) AS [# Late]
FROM 
    (SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1
LEFT JOIN
    (SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON (t1.ks = t2.ks);

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

I solved this problem on MySQL 8.0.11 with the mysql terminal command:

SET GLOBAL local_infile = true;

I mean I logged in first with the usual:

mysql -u user -p*

After that you can see the status with the command:

SHOW GLOBAL VARIABLES LIKE 'local_infile';

It should be ON. I will not be writing about security issued with loading local files into database here.

Why would you pass a parameter to a stored procedure that doesn't use it?

It sounds to me like you might be better of building dynamic SQL statements and then executing them. What you are trying to do with the SP won't work, and even if you could change what you are doing in such a way to accommodate varying numbers of parameters, you would then essentially be using dynamically generated SQL you are defeating the purpose of having/using a SP in the first place. SP's have a role, but there are not the solution in all cases.

Apps can’t be deleted if they are part of a Game Center group, in an app bundle, or currently displayed on a store. You’ll want to remove the app from sale or from the group if you want to delete it.

Take into account I didn't include the showless button.

Here's the code:

    $('#myList li').slice(0, 3).show();
    $('#loadMore').on('click', function (e) {
        e.preventDefault();
        x = x+5;
        $('#myList li').slice(0, x).slideDown();
    });
});

#myList li{display:none;
}
#loadMore {
    color:green;
    cursor:pointer;
}
#loadMore:hover {
    color:black;

That is a simple alert dialog, Federico gave you a site where you can look things up.

Here is a short example of how an alert dialog can be built.

new AlertDialog.Builder(this)
.setTitle("Title")
.setMessage("Do you really want to whatever?")
.setIcon(android.R.drawable.ic_dialog_alert)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int whichButton) {
        Toast.makeText(MainActivity.this, "Yaay", Toast.LENGTH_SHORT).show();
    }})
 .setNegativeButton(android.R.string.no, null).show();

With accordance with the answer by daveraja, here is a bash script which will solve the purpose.

Consider a situation if you are using C-shell and you want to execute a command without leaving the C-shell context/window as follows,

Command to be executed: Search exact word 'Testing' in current directory recursively only in *.h, *.c files

grep -nrs --color -w --include="*.{h,c}" Testing ./

Solution 1: Enter into bash from C-shell and execute the command

bash
grep -nrs --color -w --include="*.{h,c}" Testing ./
exit

Solution 2: Write the intended command into a text file and execute it using bash

echo 'grep -nrs --color -w --include="*.{h,c}" Testing ./' > tmp_file.txt
bash tmp_file.txt

Solution 3: Run command on the same line using bash

bash -c 'grep -nrs --color -w --include="*.{h,c}" Testing ./'

Solution 4: Create a sciprt (one-time) and use it for all future commands

alias ebash './execute_command_on_bash.sh'
ebash grep -nrs --color -w --include="*.{h,c}" Testing ./

The script is as follows,

#!/bin/bash

You can add events to objects when you create them. If you are adding the same events to multiple objects at different times, creating a named function might be the way to go.

var mouseOverHandler = function() {
    // Do stuff
};
var mouseOutHandler = function () {
    // Do stuff
};

$(function() {
    // On the document load, apply to existing elements
    $('select').hover(mouseOverHandler, mouseOutHandler);
});

// This next part would be in the callback from your Ajax call
$("<select></select>")
    .append( /* Your <option>s */ )
    .hover(mouseOverHandler, mouseOutHandler)
    .appendTo( /* Wherever you need the select box */ )
;

package main

import (
  "fmt"
)

func main() {
    var str1 = "string1"
    var str2 = "string2"
    out := fmt.Sprintf("%s %s ",str1, str2)
    fmt.Println(out)
}

This is a basic misunderstanding. Simply typing:

pgres

will result in this response:

pgres <db_name> 

It will succeed without error if the user has the permissions to access the db.

One can go into the details of the exported environment variables but that's unnecessary .. this is too basic to fail for any other reason.

The issue you are encountering is a documented feature of get_or_create.

When using keyword arguments other than "defaults" the return value of get_or_create is an instance. That's why it is showing you the parens in the return value.

you could use customer.source = Source.objects.get_or_create(name="Website")[0] to get the correct value.

Here is a link for the documentation: http://docs.djangoproject.com/en/dev/ref/models/querysets/#get-or-create-kwargs

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

document.getElementsByName("name") will get several elements called by same name . document.getElementsByName("name")[Number] will get one of them. document.getElementsByName("name")[Number].value will get the value of paticular element.

The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.

I have found that %CD% gives the path the script was called from and not the path of the script, however, %~dp0 will give the path of the script itself.

Adding images to the drawable folder is pretty simple. Just follow these steps:

1. Download the required image and save it on desktop.
2. Now, go to Android Studio and right click on drawable inside res.
3. On right clicking you will see 'Show in Explorer' or 'Reveal in Finder'.
4. Click on 'Show in Explorer' or 'Reveal in Finder' and then drag or simply copy your downloaded image into drawable folder.

Your image will be saved inside drawable and you can use it.

I looked for a solution to this problem, and came across the present page. I implemented the above solution:

$("#testdiv",opener.document) //doesn't work

But it doesn't work. Maybe it did work in previous jQuery versions, but it doesn't seem to work now.

I found this working solution on another stackoverflow page: how to access parent window object using jquery?

From which I got this working solution:

window.opener.$("#testdiv") //This works.

I like to be able to debug every aspect of my service, including any initialization in OnStart(), while still executing it with full service behavior within the framework of the SCM... no "console" or "app" mode.

I do this by creating a second service, in the same project, to use for debugging. The debug service, when started as usual (i.e. in the services MMC plugin), creates the service host process. This gives you a process to attach the debugger to even though you haven't started your real service yet. After attaching the debugger to the process, start your real service and you can break into it anywhere in the service lifecycle, including OnStart().

Because it requires very minimal code intrusion, the debug service can easily be included in your service setup project, and is easily removed from your production release by commenting out a single line of code and deleting a single project installer.

Details:

1) Assuming you are implementing MyService, also create MyServiceDebug. Add both to the ServiceBase array in Program.cs like so:

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    static void Main()
    {
        ServiceBase[] ServicesToRun;
        ServicesToRun = new ServiceBase[] 
        { 
            new MyService(),
            new MyServiceDebug()
        };
        ServiceBase.Run(ServicesToRun);
    }

2) Add the real service AND the debug service to the project installer for the service project:

Both services (real and debug) get included when you add the service project output to the setup project for the service. After installation, both services will appear in the service.msc MMC plugin.

3) Start the debug service in MMC.

4) In Visual Studio, attach the debugger to the process started by the debug service.

5) Start the real service and enjoy debugging.

If you are using zsh on an OS X, you have to edit the zshrc file.

Use vim or your favorite text editor to open zshrc file:

vim ~/.zshrc

Paste the path to adb in this file:

export PATH="/Users/{$USER}/Library/Android/sdk/platform-tools":$PATH

Run these two commands from the terminal to set User email and Name

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

 git config --global user.name "your name" 

A better JQuery answer would be:

$('#ParentContainer').scroll(function() { 
    $('#FixedDiv').animate({top:$(this).scrollTop()});
});

You can also add a number after scrollTop i.e .scrollTop() + 5 to give it buff.

A good suggestion would also to limit the duration to 100 and go from default swing to linear easing.

$('#ParentContainer').scroll(function() { 
    $('#FixedDiv').animate({top:$(this).scrollTop()},100,"linear");
})

If what you need to change is the AUTHOR OF THE LAST commit and no other is using your repository, you may undo your last commit with:

git push -f origin last_commit_hash:branch_name 

change the author name of your commit with:

git commit --amend --author "type new author here"

Exit the editor that opens and push again your code:

git push

Try LIKE construction, e.g. (assuming StudentId is of type Char, VarChar etc.)

  select * 
    from Students
   where StudentId like '%' || TEXT || '%' -- <- TEXT - text to contain

1. arg || 'default' is a great way and works for 90% of cases

2. It fails when you need to pass values that might be 'falsy'

   • false
   • 0
   • NaN
   • ""

   For these cases you will need to be a bit more verbose and check for undefined

3. Also be careful when you have optional arguments first, you have to be aware of the types of all of your arguments

Hope this helps:

// Export (file name: my-functions.js)
export const MyFunction1 = () => {}
export const MyFunction2 = () => {}
export const MyFunction3 = () => {}

// if using `eslint` (airbnb) then you will see warning, so do this:
const MyFunction1 = () => {}
const MyFunction2 = () => {}
const MyFunction3 = () => {}

export {MyFunction1, MyFunction2, MyFunction3};

// Import
import * as myFns from "./my-functions";

myFns.MyFunction1();
myFns.MyFunction2();
myFns.MyFunction3();


// OR Import it as Destructured
import { MyFunction1, MyFunction2, MyFunction3 } from "./my-functions";

// AND you can use it like below with brackets (Parentheses) if it's a function 
// AND without brackets if it's not function (eg. variables, Objects or Arrays)  
MyFunction1();
MyFunction2();

Try this:

if (value instanceof Array) {
alert('value is Array!');
} else {
alert('Not an array');
}

Do this

    <% for(int i = 0; i < allFestivals.size(); i+=1) { %>
        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>
        </tr>
    <% } %>

Better way is to use c:foreach see link jstl for each

Below working for me

display: block;
width: 100%;

Javascript isn't threaded, so a "wait" would freeze the entire page (and probably cause the browser to stop running the script entirely).

To specifically address your problem, you should remove the brackets after donothing in your setTimeout call, and make waitsecs a number not a string:

console.log('before');
setTimeout(donothing,500); // run donothing after 0.5 seconds
console.log('after');

But that won't stop execution; "after" will be logged before your function runs.

To wait properly, you can use anonymous functions:

console.log('before');
setTimeout(function(){
    console.log('after');
},500);

All your variables will still be there in the "after" section. You shouldn't chain these - if you find yourself needing to, you need to look at how you're structuring the program. Also you may want to use setInterval / clearInterval if it needs to loop.

Have you tried before and after rather than >= and <=? Also, is this a date or a timestamp?

You can delete the archive files and executable binaries that go install (or go get) produces for a package with go clean -i importpath.... These normally reside under $GOPATH/pkg and $GOPATH/bin, respectively.

Be sure to include ... on the importpath, since it appears that, if a package includes an executable, go clean -i will only remove that and not archive files for subpackages, like gore/gocode in the example below.

Source code then needs to be removed manually from $GOPATH/src.

go clean has an -n flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean). It also has a tempting -r flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!

A complete example, which you could base a script on if you like:

$ go get -u github.com/motemen/gore

$ which gore

$ go clean -i -n github.com/motemen/gore...

Since I haven't seen it in the answers above, I thought I would add my simple workaround, which is just to add a global_dict argument to the function requiring the calling module's globals, and then pass the dict into the function when calling; e.g:

# external_module
def imported_function(global_dict=None):
    print(global_dict["a"])


# calling_module
a = 12
from external_module import imported_function
imported_function(global_dict=globals())

>>> 12

dynamic_cast uses RTTI. It can slow down your application, you can use modification of the visitor design pattern to achieve downcasting without RTTI http://arturx64.github.io/programming-world/2016/02/06/lazy-visitor.html

Did you check if LAMPP is running?

sudo bash <path>/lampp start

For me, path is

sudo bash /opt/lampp/lampp start

While you can use a ForEach extension method, if you want to use just the framework you can do

collection.Select(c => {c.PropertyToSet = value; return c;}).ToList();

The ToList is needed in order to evaluate the select immediately due to lazy evaluation.

This should work!

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index", "ProductImageManeger", new  { id = id });
}

[HttpGet]
public ViewResult Index(int id)
{
    return View(_db.ProductImages.Where(rs => rs.ProductId == id).ToList());
}

Notice that you don't have to pass the name of view if you are returning the same view as implemented by the action.

Your view should inherit the model as this:

@model <Your class name>

You can then access your model in view as:

@Model.<property_name>

If you want to move the repository and keep history, you'll probably need filesystem access on both hosts. The simplest solution, if your backend is FSFS (the default on recent versions), is to make a filesystem copy of the entire repository folder.

If you have a Berkley DB backend, if you're not sure of what your backend is, or if you're changing SVN version numbers, you're going to want to use svnadmin to dump your old repository and load it into your new repository. Using svnadmin dump will give you a single file backup that you can copy to the new system. Then you can create the new (empty) repository and use svnadmin load, which will essentially replay all the commits along with its metadata (author, timestamp, etc).

You can read more about the dump/load process here:

http://svnbook.red-bean.com/en/1.8/svn.reposadmin.maint.html#svn.reposadmin.maint.migrate

Also, if you do svnadmin load, make sure you use the --force-uuid option, or otherwise people are going to have problems switching to the new repository. Subversion uses a UUID to identify the repository internally, and it won't let you switch a working copy to a different repository.

If you don't have filesystem access, there may be other third party options out there (or you can write something) to help you migrate: essentially you'd have to use the svn log to replay each revision on the new repository, and then fix up the metadata afterwards. You'll need the pre-revprop-change and post-revprop-change hook scripts in place to do this, which sort of assumes filesystem access, so YMMV. Or, if you don't want to keep the history, you can use your working copy to import into the new repository. But hopefully this isn't the case.

This question already has a great answer but in the spirit of exploring all possibilities here is another technique to reorder dom elements whilst still allowing them to take up their space, unlike the absolute positioning method.

This method works in all modern browsers and IE9+ (basically any browser that supports display:table) it has a drawback that it can only be used on a max of 3 siblings though.

//the html    
<div class='container'>
    <div class='div1'>1</div>
    <div class='div2'>2</div>
    <div class='div3'>3</div>
</div>

//the css
.container {
   display:table;    
}
.div1 {
    display:table-footer-group;
}
.div2 {
    display:table-header-group;
}
.div3 {
    display:table-row-group;
}

This will reorder the elements from 1,2,3 to 2,3,1. Basically anything with the display set to table-header-group will be positioned at the top and table-footer-group at the bottom. Naturally table-row-group puts an element in the middle.

This method is quick with good support and requires much less css than the flexbox approach so if you are only looking to swap a few items around for a mobile layout for example then dont rule out this technique.

You can check out a live demo on codepen: http://codepen.io/thepixelninja/pen/eZVgLx

var isMobileDevice = navigator.userAgent.match(/iPad|iPhone|iPod/i) != null 
    || screen.width <= 480;

If, like me, you actually wanted to load .properties files from your filesystem instead of the classpath, but otherwise keep all the smarts related to lookup, then do the following:

1. Create a subclass of java.util.ResourceBundle.Control
2. Override the newBundle() method

In this silly example, I assume you have a folder at C:\temp which contains a flat list of ".properties" files:

public class MyControl extends Control {
@Override
public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload)
        throws IllegalAccessException, InstantiationException, IOException {

    if (!format.equals("java.properties")) {
        return null;
    }

    String bundleName = toBundleName(baseName, locale);
    ResourceBundle bundle = null;

    // A simple loading approach which ditches the package      
    // NOTE! This will require all your resource bundles to be uniquely named!
    int lastPeriod = bundleName.lastIndexOf('.');

    if (lastPeriod != -1) {
        bundleName = bundleName.substring(lastPeriod + 1);
    }
    InputStreamReader reader = null;
    FileInputStream fis = null;
    try {

        File file = new File("C:\\temp\\mybundles", bundleName);

        if (file.isFile()) { // Also checks for existance
            fis = new FileInputStream(file);
            reader = new InputStreamReader(fis, Charset.forName("UTF-8"));
            bundle = new PropertyResourceBundle(reader);
        }
    } finally {
        IOUtils.closeQuietly(reader);
        IOUtils.closeQuietly(fis);
    }
    return bundle;
}

}

Note also that this supports UTF-8, which I believe isn't supported by default otherwise.

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

From my Hello World contest, Which one is Laravel? I think you can guess. I used docker container for the test and here is the results

• Laravel 5 with off log :230 rps

Safety check to only select if an item is matched.

//try to find item in list.  
ListItem oItem = DDL.Items.FindByValue("PassedValue"));
//if exists, select it.
if (oItem != null) oItem.Selected = true;

Assuming you have people is List of object

  Map<String, String> phoneBook=people.stream()
                                        .collect(toMap(Person::getName, Person::getAddress));

Now you need two steps :

1)

people =removeDuplicate(people);

2)

Map<String, String> phoneBook=people.stream()
                                        .collect(toMap(Person::getName, Person::getAddress));

Here is method to remove duplicate

public static List removeDuplicate(Collection<Person>  list) {
        if(list ==null || list.isEmpty()){
            return null;
        }

        Object removedDuplicateList =
                list.stream()
                     .distinct()
                     .collect(Collectors.toList());
     return (List) removedDuplicateList;

      }

I had a same problem with scrolling in chrome. So i removed this lines of codes from my style file.

html{height:100%;}
body{height:100%;}

Now i can play with scroll and it works:

var pos = 500;
$("html,body").animate({ scrollTop: pos }, "slow");

Here is an example I used to connect node.js to my Postgres database.

The interface in node.js that I used can be found here https://github.com/brianc/node-postgres

var pg = require('pg');
var conString = "postgres://YourUserName:YourPassword@localhost:5432/YourDatabase";

var client = new pg.Client(conString);
client.connect();

//queries are queued and executed one after another once the connection becomes available
var x = 1000;

while (x > 0) {
    client.query("INSERT INTO junk(name, a_number) values('Ted',12)");
    client.query("INSERT INTO junk(name, a_number) values($1, $2)", ['John', x]);
    x = x - 1;
}

var query = client.query("SELECT * FROM junk");
//fired after last row is emitted

query.on('row', function(row) {
    console.log(row);
});

query.on('end', function() {
    client.end();
});



//queries can be executed either via text/parameter values passed as individual arguments
//or by passing an options object containing text, (optional) parameter values, and (optional) query name
client.query({
    name: 'insert beatle',
    text: "INSERT INTO beatles(name, height, birthday) values($1, $2, $3)",
    values: ['George', 70, new Date(1946, 02, 14)]
});

//subsequent queries with the same name will be executed without re-parsing the query plan by postgres
client.query({
    name: 'insert beatle',
    values: ['Paul', 63, new Date(1945, 04, 03)]
});
var query = client.query("SELECT * FROM beatles WHERE name = $1", ['john']);

//can stream row results back 1 at a time
query.on('row', function(row) {
    console.log(row);
    console.log("Beatle name: %s", row.name); //Beatle name: John
    console.log("Beatle birth year: %d", row.birthday.getYear()); //dates are returned as javascript dates
    console.log("Beatle height: %d' %d\"", Math.floor(row.height / 12), row.height % 12); //integers are returned as javascript ints
});

//fired after last row is emitted
query.on('end', function() {
    client.end();
});

UPDATE:- THE query.on function is now deprecated and hence the above code will not work as intended. As a solution for this look at:- query.on is not a function

string = string.replace(/[\W_]/g, "_");

If you are on Android it makes it hard to see when you add new folders or assets to your project - BUT if you change the dropdown to PROJECT then the file directory will match the file system on your computer, then go to:

app > src > main > res

From here you can find the conventional Eclipse type files like drawable/drawable-hdpi/drawable-mdpi and so on where you can easily drag and drop files into or import into and instantly see them. As soon as you see your files here they will be available when going to assign image src's and so on.

Good luck Android Warriors in a strange new world!

Just run this verbatim.

import nltk
nltk.download('tagsets')
nltk.help.upenn_tagset()

nltk.tag._POS_TAGGER won't work. It will give AttributeError: module 'nltk.tag' has no attribute '_POS_TAGGER'. It's not available in NLTK 3 anymore.

If you are merely looking to load a group of related classes, then Spring can help you.

Spring can instantiate a list or map of all classes that implement a given interface in one line of code. The list or map will contain instances of all the classes that implement that interface.

That being said, as an alternative to loading the list of classes out of the file system, instead just implement the same interface in all the classes you want to load, regardless of package and use Spring to provide you instances of all of them. That way, you can load (and instantiate) all the classes you desire regardless of what package they are in.

On the other hand, if having them all in a package is what you want, then simply have all the classes in that package implement a given interface.

As of SQL Server 2012+, you can use FORMAT(value, format [, culture ])

Where the format param takes any valid standard format string or custom formatting string

Example:

SELECT FORMAT(GETDATE(), 'MM/dd/yyyy')

You can use calc to position element relative to center. For example if you want to position element 200px right from the center .. you can do this :

#your_element{
    position:absolute;
    left: calc(50% + 200px);
}

Dont forget this

When you use signs + and - you must have one blank space between sign and number, but when you use signs * and / there is no need for blank space.
