If you are looking for a vertical line use this drawable.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:top="-8dp"
        android:bottom="-8dp"
        android:left="-8dp">
        <shape>
            <solid android:color="@android:color/transparent"/>
            <stroke
                android:width="4dp"
                android:color="#ffffff"
                android:dashGap="4dp"
                android:dashWidth="4dp"/>
        </shape>
    </item>
</layer-list>

The negative top bottom and left values remove the unwanted sides of the shape leaving a single dashed line.

Use it in a view like so.

<View
android:layout_width="4dp"
android:layout_height="match_parent"
android:background="@drawable/dash_line_vertical"
android:layerType="software" />

A simple function that makes GIFs:

Web page automation ? Definitely "webbot"

webbot even works web pages which have dynamically changing id and classnames and has more methods and features than selenium or mechanize.

Here's a snippet :)

from webbot import Browser 
web = Browser()
web.go_to('google.com') 
web.click('Sign in')
web.type('[email protected]' , into='Email')
web.click('NEXT' , tag='span')
web.type('mypassword' , into='Password' , id='passwordFieldId') # specific selection
web.click('NEXT' , tag='span') # you are logged in ^_^

The docs are also pretty straight forward and simple to use : https://webbot.readthedocs.io

EDIT (02 Jan 2012):

I created a small open source Android Library Project that streamlines this process, while also providing a built-in file explorer (in case the user does not have one present). It's extremely simple to use, requiring only a few lines of code.

You can find it at GitHub: aFileChooser.

ORIGINAL

If you want the user to be able to choose any file in the system, you will need to include your own file manager, or advise the user to download one. I believe the best you can do is look for "openable" content in an Intent.createChooser() like this:

private static final int FILE_SELECT_CODE = 0;

private void showFileChooser() {
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("*/*"); 
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File to Upload"),
                FILE_SELECT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(this, "Please install a File Manager.", 
                Toast.LENGTH_SHORT).show();
    }
}

You would then listen for the selected file's Uri in onActivityResult() like so:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case FILE_SELECT_CODE:
        if (resultCode == RESULT_OK) {
            // Get the Uri of the selected file 
            Uri uri = data.getData();
            Log.d(TAG, "File Uri: " + uri.toString());
            // Get the path
            String path = FileUtils.getPath(this, uri);
            Log.d(TAG, "File Path: " + path);
            // Get the file instance
            // File file = new File(path);
            // Initiate the upload
        }
        break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

The getPath() method in my FileUtils.java is:

public static String getPath(Context context, Uri uri) throws URISyntaxException {
    if ("content".equalsIgnoreCase(uri.getScheme())) {
        String[] projection = { "_data" };
        Cursor cursor = null;

        try {
            cursor = context.getContentResolver().query(uri, projection, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow("_data");
            if (cursor.moveToFirst()) {
                return cursor.getString(column_index);
            }
        } catch (Exception e) {
            // Eat it
        }
    }
    else if ("file".equalsIgnoreCase(uri.getScheme())) {
        return uri.getPath();
    }

    return null;
} 

I realized that I was iterating over a list of lists where some of them were empty. I fixed this by adding this preprocessing step:

tfidfLsNew = [x for x in tfidfLs if x != []]

the len() of the original was 3105, and the len() of the latter was 3101, implying that four of my lists were completely empty. After this preprocess my max() min() etc. were functioning again.

Just use Kotlin!

val list = listOf(user1, user2, user3)
val maxDate = list.maxBy { it.date }?.date

Looking for a similar solution I just came across this brand new tutorial, which lets you bridge a Swift gradient background (https://github.com/soffes/GradientView) library while walking through every step to get a working React component.

It is a step-by-step tutorial, allowing you to build your own component by bridging the swift and objective-c component into a usable React Native component, which overrides the standard View component and allows you to define a gradient like the following:

 <LinearGradient 
   style={styles.gradient} 
   locations={[0, 1.0]} 
   colors={['#5ED2A0', '#339CB1']}
 />

You can find the tutorial here: http://browniefed.com/blog/2015/11/28/react-native-how-to-bridge-a-swift-view/

This is one of the reasons why C++ introduced the new cast style, which includes static_cast and reinterpret_cast

There's two things you can mean by saying conversion from signed to unsigned, you might mean that you wish the unsigned variable to contain the value of the signed variable modulo the maximum value of your unsigned type + 1. That is if your signed char has a value of -128 then CHAR_MAX+1 is added for a value of 128 and if it has a value of -1, then CHAR_MAX+1 is added for a value of 255, this is what is done by static_cast. On the other hand you might mean to interpret the bit value of the memory referenced by some variable to be interpreted as an unsigned byte, regardless of the signed integer representation used on the system, i.e. if it has bit value 0b10000000 it should evaluate to value 128, and 255 for bit value 0b11111111, this is accomplished with reinterpret_cast.

Now, for the two's complement representation this happens to be exactly the same thing, since -128 is represented as 0b10000000 and -1 is represented as 0b11111111 and likewise for all in between. However other computers (usually older architectures) may use different signed representation such as sign-and-magnitude or ones' complement. In ones' complement the 0b10000000 bitvalue would not be -128, but -127, so a static cast to unsigned char would make this 129, while a reinterpret_cast would make this 128. Additionally in ones' complement the 0b11111111 bitvalue would not be -1, but -0, (yes this value exists in ones' complement,) and would be converted to a value of 0 with a static_cast, but a value of 255 with a reinterpret_cast. Note that in the case of ones' complement the unsigned value of 128 can actually not be represented in a signed char, since it ranges from -127 to 127, due to the -0 value.

I have to say that the vast majority of computers will be using two's complement making the whole issue moot for just about anywhere your code will ever run. You will likely only ever see systems with anything other than two's complement in very old architectures, think '60s timeframe.

The syntax boils down to the following:

signed char x = -100;
unsigned char y;

y = (unsigned char)x;                    // C static
y = *(unsigned char*)(&x);               // C reinterpret
y = static_cast<unsigned char>(x);       // C++ static
y = reinterpret_cast<unsigned char&>(x); // C++ reinterpret

To do this in a nice C++ way with arrays:

jbyte memory_buffer[nr_pixels];
unsigned char* pixels = reinterpret_cast<unsigned char*>(memory_buffer);

or the C way:

unsigned char* pixels = (unsigned char*)memory_buffer;

In SQL Server Management Studio you can right click on the database you want to replicate, and select "Script Database as" to have the tool create the appropriate SQL file to replicate that database on another server. You can repeat this process for each table you want to create, and then merge the files into a single SQL file. Don't forget to add a using statement after you create your Database but prior to any table creation.

In more recent versions of SQL Server you can get this in one file in SSMS.

1. Right click a database.
2. Tasks
3. Generate Scripts

This will launch a wizard where you can script the entire database or just portions. There does not appear to be a T-SQL way of doing this.

Just need to set the value property in a convenient place (such as InitializeComponent()):

    dateTimePicker1.Value = DateTime.Today.AddDays(-1);

I suspect you did not know that there are different & escapes in HTML. The W3C you can see the codes. &times means × in HTML code. Use &times instead.

I know this question is quite old, but here's a library that encapsulates the ProcessBuilder api.

$myVar = $someVar ?? 42;

Is equivalent to :

$myVar = isset($someVar) ? $someVar : 42;

For constants, the behaviour is the same when using a constant that already exists :

define("FOO", "bar");
define("BAR", null);

$MyVar = FOO ?? "42";
$MyVar2 = BAR ?? "42";

echo $MyVar . PHP_EOL;  // bar
echo $MyVar2 . PHP_EOL; // 42

However, for constants that don't exist, this is different :

$MyVar3 = IDONTEXIST ?? "42"; // Raises a warning
echo $MyVar3 . PHP_EOL;       // IDONTEXIST

Warning: Use of undefined constant IDONTEXIST - assumed 'IDONTEXIST' (this will throw an Error in a future version of PHP)

Php will convert the non-existing constant to a string.

You can use constant("ConstantName") that returns the value of the constant or null if the constant doesn't exist, but it will still raise a warning. You can prepended the function with the error control operator @ to ignore the warning message :

$myVar = @constant("IDONTEXIST") ?? "42"; // No warning displayed anymore
echo $myVar . PHP_EOL; // 42

you could also try creating a button, this will work if you put it outside of the form;

<button onClick="moreFields(); return false;">Give me more fields!</button>

Or, for Python 3:

for k,v in dict.items():
    print(k, v)

For completeness:

Along the lines of Chase's answer, I usually use as.data.frame to coerce the matrix to a data.frame:

m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))

EDIT: speed test data.frame vs. as.data.frame

system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  8.005   0.108   8.165 

system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  3.759   0.048   3.802 

Yes, it appears to be faster (by about 2 times).

addToCart(docId: string, prodId: string): Promise<void> {
    return this.baseAngularFirestore.collection('carts').doc(docId).update({
        products:
        firestore.FieldValue.arrayUnion({
            productId: prodId,

        }),
    });
}

In new version of jquery, could done it via following steps:

• get param array via serializeArray()
• call push() or similar methods to add additional params to the array,
• call $.param(arr) to get serialized string, which could be used as jquery ajax's data param.

Example code:

var paramArr = $("#loginForm").serializeArray();
paramArr.push( {name:'size', value:7} );
$.post("rest/account/login", $.param(paramArr), function(result) {
    // ...
}

You can make use of ImageIO in order to load the image from an URL and then write it to a file. Something like this:

URL url = new URL("http://google.com/pathtoaimage.jpg");
BufferedImage img = ImageIO.read(url);
File file = new File("downloaded.jpg");
ImageIO.write(img, "jpg", file);

This also allows you to convert the image to some other format if needed.

Use Range("A1").Text instead of .Value

post comment edit:
Why?
Because the .Text property of Range object returns what is literally visible in the spreadsheet, so if you cell displays for example i100l:25he*_92 then <- Text will return exactly what it in the cell including any formatting.
The .Value and .Value2 properties return what's stored in the cell under the hood excluding formatting. Specially .Value2 for date types, it will return the decimal representation.

If you want to dig deeper into the meaning and performance, I just found this article which seems like a good guide

another edit
Here you go @Santosh
type in (MANUALLY) the values from the DEFAULT (col A) to other columns
Do not format column A at all
Format column B as Text
Format column C as Date[dd/mm/yyyy]
Format column D as Percentage

now,
paste this code in a module

Sub main()

    Dim ws As Worksheet, i&, j&
    Set ws = Sheets(1)
    For i = 3 To 7
        For j = 1 To 4
            Debug.Print _
                    "row " & i & vbTab & vbTab & _
                    Cells(i, j).Text & vbTab & _
                    Cells(i, j).Value & vbTab & _
                    Cells(i, j).Value2
        Next j
    Next i
End Sub

and Analyse the output! Its really easy and there isn't much more i can do to help :)

This is the variable for the current value in the pipe line, which is called $PSItem in Powershell 3 and newer.

1,2,3 | %{ write-host $_ } 

or

1,2,3 | %{ write-host $PSItem } 

For example in the above code the %{} block is called for every value in the array. The $_ or $PSItem variable will contain the current value.

Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.

The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.

The native PHP function mail() does not work for me. It issues the message:

503 This mail server requires authentication when attempting to send to a non-local e-mail address

So, I usually use PHPMailer package

I've downloaded the version 5.2.23 from: GitHub.

I've just picked 2 files and put them in my source PHP root

class.phpmailer.php
class.smtp.php

In PHP, the file needs to be added

require_once('class.smtp.php');
require_once('class.phpmailer.php');

After this, it's just code:

require_once('class.smtp.php');
require_once('class.phpmailer.php');
... 
//----------------------------------------------
// Send an e-mail. Returns true if successful 
//
//   $to - destination
//   $nameto - destination name
//   $subject - e-mail subject
//   $message - HTML e-mail body
//   altmess - text alternative for HTML.
//----------------------------------------------
function sendmail($to,$nameto,$subject,$message,$altmess)  {

  $from  = "[email protected]";
  $namefrom = "yourname";
  $mail = new PHPMailer();  
  $mail->CharSet = 'UTF-8';
  $mail->isSMTP();   // by SMTP
  $mail->SMTPAuth   = true;   // user and password
  $mail->Host       = "localhost";
  $mail->Port       = 25;
  $mail->Username   = $from;  
  $mail->Password   = "yourpassword";
  $mail->SMTPSecure = "";    // options: 'ssl', 'tls' , ''  
  $mail->setFrom($from,$namefrom);   // From (origin)
  $mail->addCC($from,$namefrom);      // There is also addBCC
  $mail->Subject  = $subject;
  $mail->AltBody  = $altmess;
  $mail->Body = $message;
  $mail->isHTML();   // Set HTML type
//$mail->addAttachment("attachment");  
  $mail->addAddress($to, $nameto);
  return $mail->send();
}

It works like a charm

from os.path import dirname, join as pjoin
import scipy.io as sio
data_dir = pjoin(dirname(sio.__file__), 'matlab', 'tests', 'data')
mat_fname = pjoin(data_dir, 'testdouble_7.4_GLNX86.mat')
mat_contents = sio.loadmat(mat_fname)

You can use above code to read the default saved .mat file in Python.

I know that best way is str.indexOf(s) !== -1; http://hayageek.com/javascript-string-contains/

I suggest another way(str.replace(s1, "") !== str):

var str = "Hello World!", s1 = "ello", s2 = "elloo";_x000D_
alert(str.replace(s1, "") !== str);_x000D_
alert(str.replace(s2, "") !== str);

Java 8 solution (like this but a bit simpler):

public static List<String> partition(String string, int partSize) {
  List<String> parts = IntStream.range(0, string.length() / partSize)
    .mapToObj(i -> string.substring(i * partSize, (i + 1) * partSize))
    .collect(toList());
  if ((string.length() % partSize) != 0)
    parts.add(string.substring(string.length() / partSize * partSize));
  return parts;
}

Just start from there that in CSS, if you repeat 2 values or more, always last one gets applied, unless using !important tag, but at the same time avoid using !important as much as you can, so in your case that's the problem, so the second transform override the first one in this case...

So how you can do what you want then?...

Don't worry, transform accepts multiple values at the same time... So this code below will work:

li:nth-child(2) {
  transform: rotate(15deg) translate(-20px, 0px); //multiple
}

If you like to play around with transform run the iframe from MDN below:

<iframe src="https://interactive-examples.mdn.mozilla.net/pages/css/transform.html" class="interactive  " width="100%" frameborder="0" height="250"></iframe>

Look at the link below for more info:

The usual way to use assertRaises is to call a function:

self.assertRaises(TypeError, test_function, args)

to test that the function call test_function(args) raises a TypeError.

The problem with self.testListNone[:1] is that Python evaluates the expression immediately, before the assertRaises method is called. The whole reason why test_function and args is passed as separate arguments to self.assertRaises is to allow assertRaises to call test_function(args) from within a try...except block, allowing assertRaises to catch the exception.

Since you've defined self.testListNone = None, and you need a function to call, you might use operator.itemgetter like this:

import operator
self.assertRaises(TypeError, operator.itemgetter, (self.testListNone,slice(None,1)))

since

operator.itemgetter(self.testListNone,slice(None,1))

is a long-winded way of saying self.testListNone[:1], but which separates the function (operator.itemgetter) from the arguments.

>>> [1,2,3,4,5,6,7,8,9][:5]
[1, 2, 3, 4, 5]
>>> [1,2,3][:5]
[1, 2, 3]

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.

data = json.loads('{"lat":444, "lon":555}')
    ret = ''
    for j in data:
        ret = ret+" "+data[j]
return ret

When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch class. The property on (boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.

As far as I can tell, both syntaxes are equivalent. The first is SQL standard, the second is MySQL's extension.

So they should be exactly equivalent performance wise.

http://dev.mysql.com/doc/refman/5.6/en/insert.html says:

INSERT inserts new rows into an existing table. The INSERT ... VALUES and INSERT ... SET forms of the statement insert rows based on explicitly specified values. The INSERT ... SELECT form inserts rows selected from another table or tables.

Following many hours of search and testing i found following solution(by implementing different SO solutions) here it what didn't failed in any case i was getting crash.

     Runnable runnable = new Runnable() {
            @Override
            public void run() {

          //displayPopup,progress dialog or what ever action. example

                ProgressDialogBox.setProgressBar(Constants.LOADING,youractivityName.this);
            }};

Where logcat is indicating the crash is happening.. start a runnable .in my case at receiving broadcast.

runOnUiThread(new Runnable() {
            @Override
            public void run() {

I will answer this question in terms of AngularFire, Firebase's library for Angular.

1. Tl;dr: superpowers. :-)

2. AngularFire's three-way data binding. Angular binds the view and the $scope, i.e., what your users do in the view automagically updates in the local variables, and when your JavaScript updates a local variable the view automagically updates. With Firebase the cloud database also updates automagically. You don't need to write $http.get or $http.put requests, the data just updates.

3. Five-way data binding, and seven-way, nine-way, etc. I made a tic-tac-toe game using AngularFire. Two players can play together, with the two views updating the two $scopes and the cloud database. You could make a game with three or more players, all sharing one Firebase database.

4. AngularFire's OAuth2 library makes authorization easy with Facebook, GitHub, Google, Twitter, tokens, and passwords.

5. Double security. You can set up your Angular routes to require authorization, and set up rules in Firebase about who can read and write data.

6. There's no back end. You don't need to make a server with Node and Express. Running your own server can be a lot of work, require knowing about security, require that someone do something if the server goes down, etc.

7. Fast. If your server is in San Francisco and the client is in San Jose, fine. But for a client in Bangalore connecting to your server will be slower. Firebase is deployed around the world for fast connections everywhere.

Usually you can find a program under a subdirectory "../bin". System programs are under /usr/bin or /bin. To check where files of mysql package are placed, on RHEL 6 type like this :

rpm -ql mysql (which is the main part of the package)

and the result is a list of "exe" files such as "mysqladmin" tool. About to know the version of the server, run the command:

mysqladmin -u "valid-user" version

To avoid conflicts with array index using unset - see https://stackoverflow.com/a/49626928/3223785 and https://stackoverflow.com/a/47798640/3223785 for more information - reassign the array to itself: ARRAY_VAR=(${ARRAY_VAR[@]}).

#!/bin/bash

ARRAY_VAR=(0 1 2 3 4 5 6 7 8 9)
unset ARRAY_VAR[5]
unset ARRAY_VAR[4]
ARRAY_VAR=(${ARRAY_VAR[@]})
echo ${ARRAY_VAR[@]}
A_LENGTH=${#ARRAY_VAR[*]}
for (( i=0; i<=$(( $A_LENGTH -1 )); i++ )) ; do
    echo ""
    echo "INDEX - $i"
    echo "VALUE - ${ARRAY_VAR[$i]}"
done

exit 0

[Ref.: https://tecadmin.net/working-with-array-bash-script/ ]

dict1 is a symbol that references an underlying dictionary object. Assigning dict1 to dict2 merely assigns the same reference. Changing a key's value via the dict2 symbol changes the underlying object, which also affects dict1. This is confusing.

It is far easier to reason about immutable values than references, so make copies whenever possible:

person = {'name': 'Mary', 'age': 25}
one_year_later = {**person, 'age': 26}  # does not mutate person dict

This is syntactically the same as:

one_year_later = dict(person, age=26)

var intTried = Convert.ChangeType(myObject, typeof(int)) as int?;

If there is a strong concern about speed and performance, the best approach is to verify the code produced by the compiler at the assembly level.

For instance, the following code shows that the "do-while" is a bit faster. This because the "jmp" instruction is not used by the "do-while" loop.

BTW, in this specific example, the worst case is given by the "for" loop. :))

int main(int argc, char* argv[])
{
    int i;
    char x[100];

    // "FOR" LOOP:
    for (i=0; i<100; i++ )
    {
        x[i] = 0;
    }

    // "WHILE" LOOP:
    i = 0;
    while (i<100 )

    i = 0;
    do
    {
        x[i++] = 0;
    }
    while (i<100);

    return 0;
}

The line function implementation should be:

void addStudent(struct student person) {

}

person is not a type but a variable, you cannot use it as the type of a function parameter.

Also, make sure your struct is defined before the prototype of the function addStudent as the prototype uses it.

Not sure why no one is using semicolons. This is how it works for me:

=CONCATENATE(LEFT(A1;1); B1)

Solutions with comma produce an error in Excel.

Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:

myDate : Date;

I think the answer is much easier.

To hide the tab you just can use the way you already tried or adressing the TabPage itself.

TabControl1.TabPages.Remove(TabPage1) 'Could be male
TabControl1.TabPages.Remove(TabPage2) 'Could be female

a.s.o.

Removing the TabPage does not destroy it and the controls on it. To show the corresponding tab again just use the following code

TabControl1.TabPages.Insert(0, TabPage1) 'Show male
TabControl1.TabPages.Insert(1, TabPage2) 'Show female

You're pretty close, you just need to replace the = with a :. You can use an object type literal (see spec section 3.5.3) or an interface. Using an object type literal is close to what you have:

var obj: { property: string; } = { property: "foo" };

But you can also use an interface

interface MyObjLayout {
    property: string;
}

var obj: MyObjLayout = { property: "foo" };

Change

id.equals(list[pos].getItemNumber())

to

id == list[pos].getItemNumber()

For more details, you should learn the difference between the primitive types like int, char, and double and reference types.

Instead of defining the width, you could just put a margin-left on your li, so that the spacing is consistent, and just make sure the margin(s)+li fit within 900px.

nav li {
  line-height: 87px;
  float: left;
  text-align: center;
  margin-left: 35px;
}

Hope this helps.

Alternative solution that uses .query() method:

In [5]: df.query("countries in @countries")
Out[5]:
  countries
1        UK
3     China

In [6]: df.query("countries not in @countries")
Out[6]:
  countries
0        US
2   Germany

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

You can do:

x = re.findall('\d+', text)
result = x[0] if len(x) > 0 else ''

Note that your question isn't exactly related to regex. Rather, how do you safely find an element from an array, if it has none.

You can use eval() for this purpose

>>> url = "'http address'"
>>> eval(url)
'http address'

while eval() poses risk , i think in this context it is safe.

Perhaps bool is a tad "lighter" than Boolean; Interestingly, changing this:

namespace DuckbillServerWebAPI.Models
{
    public class Expense
    {
        . . .
        public bool CanUseOnItems { get; set; }
    }
}

...to this:

namespace DuckbillServerWebAPI.Models
{
    public class Expense
    {
        . . .
        public Boolean CanUseOnItems { get; set; }
    }
}

...caused my cs file to sprout a "using System;" Changing the type back to "bool" caused the using clause's hair to turn grey.

(Visual Studio 2010, WebAPI project)

I had the same problem. The hosts file is corrupted! there were:

localhos 127.0.0.1

localhost 127.0.0.1

localhos 127.0.0.1
localhos 127.0.0.1

The result is that localhost is not defined.

Solution: edit the hosts file with admin rights and correct to only one entry:

localhost 127.0.0.1

If you do not have privilege for "Show Status" then, The best option is to, create two triggers and a new table which keeps the row count of your billion records table.

Example:

TableA >> Billion Records
TableB >> 1 Column and 1 Row

Whenever there is insert query on TableA(InsertTrigger), Increment the row value by 1 TableB
Whenever there is delete query on TableA(DeleteTrigger), Decrement the row value by 1 in TableB

Your format string is wrong. Change it to

insert = DateTime.ParseExact(line[i], "M/d/yyyy hh:mm", CultureInfo.InvariantCulture);

Using LINQ you can do it like this:

var table_enum = table

    // Convert to IEnumerable<string>
    .OfType<string>()

    // Create anonymous type where Index1 and Index2
    // reflect the indices of the 2-dim. array
    .Select((_string, _index) => new {
        Index1 = (_index / 2),
        Index2 = (_index % 2), // ? I added this only for completeness
        Value = _string
    })

    // Group by Index1, which generates IEnmurable<string> for all Index1 values
    .GroupBy(v => v.Index1)

    // Convert all Groups of anonymous type to String-Arrays
    .Select(group => group.Select(v => v.Value).ToArray());

// Now you can use the foreach-Loop as you planned
foreach(string[] str_arr in table_enum) {
    // …
}

This way it is also possible to use the foreach for looping through the columns instead of the rows by using Index2 in the GroupBy instead of Index 1. If you don't know the dimension of your array then you have to use the GetLength() method to determine the dimension and use that value in the quotient.

you can use implicit casting AddWithValue

cmd.Parameters.AddWithValue("@param1", klantId);
cmd.Parameters.AddWithValue("@param2", klantNaam);
cmd.Parameters.AddWithValue("@param3", klantVoornaam);

sample code,

using (SqlConnection conn = new SqlConnection("connectionString"))

        cmd.Connection = conn;
        cmd.CommandType = CommandType.Text;

                            VALUES(@param1,@param2,@param3)";  

        cmd.Parameters.AddWithValue("@param1", klantId);  
        cmd.Parameters.AddWithValue("@param2", klantNaam);  
        cmd.Parameters.AddWithValue("@param3", klantVoornaam);  

        try
        {
            conn.Open();
            cmd.ExecuteNonQuery(); 
        }
        catch(SqlException e)
        {
            MessgeBox.Show(e.Message.ToString(), "Error Message");

Quick and dirty function that'll left click wherever clicks times on Windows 7 using the ctypes library. No downloads required.

import ctypes

SetCursorPos = ctypes.windll.user32.SetCursorPos
mouse_event = ctypes.windll.user32.mouse_event

def left_click(x, y, clicks=1):
  SetCursorPos(x, y)
  for i in xrange(clicks):
   mouse_event(2, 0, 0, 0, 0)
   mouse_event(4, 0, 0, 0, 0)

left_click(200, 200) #left clicks at 200, 200 on your screen. Was able to send 10k clicks instantly.

Also can use without parent

say router definition like:

{path:'/about',    name: 'About',   component: AboutComponent}

then can navigate by name instead of path

goToAboutPage() {
    this.router.navigate(['About']); // here "About" is name not path
}

Updated for V2.3.0

In Routing from v2.0 name property no more exist. route define without name property. so you should use path instead of name. this.router.navigate(['/path']) and no leading slash for path so use path: 'about' instead of path: '/about'

router definition like:

{path:'about', component: AboutComponent}

then can navigate by path

goToAboutPage() {
    this.router.navigate(['/about']); // here "About" is path
}

Try to Use:

SELECT linkorder
    ,Row_Number() OVER (
        PARTITION BY linkorder ORDER BY linkorder DESC
        ) AS RowNum
FROM u_links

For the people which are looking for the opposite (aka fullscreen), it's very simple. Because you just have to replace the settings /min by /max.

Now the program will be open at the "maximized" size ! In the case, perhaps you will need an example : start /max explorer.exe.

I use a simple one inline statement

<asp:TextBox ID="txtLocatorName" runat="server"
 style="text-transform:uppercase" CssClass="textbox"  
 TabIndex="1">
</asp:TextBox>

If you don't want to use css classes you can just use inline style statement.(This one just visibly make uppercase) :)

On Server side use

string UCstring = txtName.Text.ToUpper();

a simple way would be to cast the dates into timestamps and take their difference and then extract the DAY part.

if you want real difference

select extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp);

if you want absolute difference

select abs(extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp));

Another difference to pay attention to is handling of undefined values:

mergeInto = { a: 1}
toMerge = {a : undefined, b:undefined}
lodash.extend({}, mergeInto, toMerge) // => {a: undefined, b:undefined}
lodash.merge({}, mergeInto, toMerge)  // => {a: 1, b:undefined}

So merge will not merge undefined values into defined values.

REVISED - please see Andrew_1510's answer below, as IPython has been updated.

...

It was a bit hard figure out how to get there from a dusty bug report, but:

It ships with IPython now!

import ipy_autoreload
%autoreload 2
%aimport your_mod

# %autoreload? for help

... then every time you call your_mod.dwim(), it'll pick up the latest version.

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

See babel repl transpiled code.

The % operator is for integers. You're looking for the fmod() function.

#include <cmath>

int main()
{
    double x = 6.3;
    double y = 2.0;
    double z = std::fmod(x,y);

}

This solution also work for background menu: http://www.roggel.com/NGNeer/BackgroundCMD/

Download the GAPPS Package

Next we need to pull down the appropriate Google Apps package that matches our Android AVD version. In this case we’ll be using the 'gapps-lp-20141109-signed.zip' package. You can download that file from BasketBuild here.

[pyoor@localhost]$ md5sum gapps-lp-20141109-signed.zip
367ce76d6b7772c92810720b8b0c931e gapps-lp-20141109-signed.zip

In order to install Google Play, we’ll need to push the following 4 APKs to our AVD (located in ./system/priv-app/):

GmsCore.apk, GoogleServicesFramework.apk, GoogleLoginService.apk, Phonesky.apk

[pyoor@localhost]$ unzip -j gapps-lp-20141109-signed.zip \
system/priv-app/GoogleServicesFramework/GoogleServicesFramework.apk \
system/priv-app/GoogleLoginService/GoogleLoginService.apk \
system/priv-app/Phonesky/Phonesky.apk \
system/priv-app/GmsCore/GmsCore.apk -d ./

Push APKs to the Emulator

With our APKs extracted, let’s launch our AVD using the following command.

[pyoor@localhost tools]$ ./emulator @<YOUR_DEVICE_NAME> -no-boot-anim

This may take several minutes the first time as the AVD is created. Once started, we need to remount the AVDs system partition as read/write so that we can push our packages onto the device.

[pyoor@localhost]$ cd ~/android-sdk/platform-tools/
[pyoor@localhost platform-tools]$ ./adb remount

Next, push the APKs to our AVD:

[pyoor@localhost platform-tools]$ ./adb push GmsCore.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleServicesFramework.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push GoogleLoginService.apk /system/priv-app/
[pyoor@localhost platform-tools]$ ./adb push Phonesky.apk /system/priv-app

Profit!

And finally, reboot the emualator using the following commands:

[pyoor@localhost platform-tools]$ ./adb shell stop && ./adb shell start

Once the emulator restarts, we should see the Google Play package appear within the menu launcher. After associating a Google account with this AVD we now have a fully working version of Google Play running under our emulator.

You might need to allow different combinations of data in your intent filter to get it to work in different cases (http/ vs https/, www. vs no www., etc).

For example, I had to do the following for an app which would open when the user opened a link to Google Drive forms (www.docs.google.com/forms)

Note that path prefix is optional.

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data android:scheme="http" />
            <data android:scheme="https" />

            <data android:host="www.docs.google.com" />
            <data android:host="docs.google.com" />

            <data android:pathPrefix="/forms" />

            file = new File("c:\\New.doc");
            FileInputStream fis = new FileInputStream(file.getAbsolutePath());
            HWPFDocument document = new HWPFDocument(fis);
            extractor = new WordExtractor(document);
            String[] fileData = extractor.getParagraphText();
            for (int i = 0; i < fileData.length; i++)
            {
                if (fileData[i] != null)
                    System.out.println(fileData[i]);
            }
        }
        catch (Exception exep)

            exep.printStackTrace();

In Ghost4J library (http://ghost4j.sourceforge.net), since version 0.4.0 you can use a SimpleRenderer to do the job with few lines of code:

1. Load PDF or PS file (use PSDocument class for that):

       PDFDocument document = new PDFDocument();
       document.load(new File("input.pdf"));
   

2. Create the renderer

       SimpleRenderer renderer = new SimpleRenderer();
   
       // set resolution (in DPI)
       renderer.setResolution(300);
   

3. Render

       List<Image> images = renderer.render(document);
   

Then you can do what you want with your image objects, for example, you can write them as PNG like this:

            for (int i = 0; i < images.size(); i++) {
                ImageIO.write((RenderedImage) images.get(i), "png", new File((i + 1) + ".png"));
            }

Note: Ghost4J uses the native Ghostscript C API so you need to have a Ghostscript installed on your box.

I hope it will help you :)

I'm not fully sure that this is what you're looking for, but if your question is how to read an integer using <stdio.h>, then the proper syntax is

int myInt;
scanf("%d", &myInt);

You'll need to do a lot of error-handling to ensure that this works correctly, of course, but this should be a good start. In particular, you'll need to handle the cases where

1. The stdin file is closed or broken, so you get nothing at all.
2. The user enters something invalid.

To check for this, you can capture the return code from scanf like this:

int result = scanf("%d", &myInt);

If stdin encounters an error while reading, result will be EOF, and you can check for errors like this:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}

If, on the other hand, the user enters something invalid, like a garbage text string, then you need to read characters out of stdin until you consume all the offending input. You can do this as follows, using the fact that scanf returns 0 if nothing was read:

int myInt;
int result = scanf("%d", &myInt);

if (result == EOF) {
    /* ... you're not going to get any input ... */
}
if (result == 0) {
    while (fgetc(stdin) != '\n') // Read until a newline is found
        ;
}

Hope this helps!

EDIT: In response to the more detailed question, here's a more appropriate answer. :-)

The problem with this code is that when you write

printf("got the number: %d", scanf("%d", &x));

This is printing the return code from scanf, which is EOF on a stream error, 0 if nothing was read, and 1 otherwise. This means that, in particular, if you enter an integer, this will always print 1 because you're printing the status code from scanf, not the number you read.

To fix this, change this to

int x;
scanf("%d", &x);
/* ... error checking as above ... */
printf("got the number: %d", x);

Hope this helps!

Use json_decode to transform your JSON into a PHP array. Example:

$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b

As Thomas Owens pointed out, simply concatenating the files will leave multiple ID3 headers scattered throughout the resulting concatenated file - so the time/bitrate info will be wildly wrong.

You're going to need to use a tool which can combine the audio data for you.

mp3wrap would be ideal for this - it's designed to join together MP3 files, without needing to decode + re-encode the data (which would result in a loss of audio quality) and will also deal with the ID3 tags intelligently.

The resulting file can also be split back into its component parts using the mp3splt tool - mp3wrap adds information to the IDv3 comment to allow this.

Inside your .idea folder, change workspace.xml file

I use this function in my python programs. The input for the function is as example:
value = time.time()

def stopWatch(value):
    '''From seconds to Days;Hours:Minutes;Seconds'''

    valueD = (((value/365)/24)/60)
    Days = int (valueD)

    valueH = (valueD-Days)*365
    Hours = int(valueH)

    valueM = (valueH - Hours)*24
    Minutes = int(valueM)

    valueS = (valueM - Minutes)*60
    Seconds = int(valueS)


    print Days,";",Hours,":",Minutes,";",Seconds




start = time.time() # What in other posts is described is

***your code HERE***

end = time.time()         
stopWatch(end-start) #Use then my code

Although an old question all the contributions helped me a lot so here's my solution, which works within my own DbContext class. The $rows parameter is simply an array of associative arrays representing rows or models: field name => insert value.

If you use a pattern that uses models this fits in nicely when passed model data as an array, say from a ToRowArray method within the model class.

Note: It should go without saying but never allow the arguments passed to this method to be exposed to the user or reliant on any user input, other than the insert values, which have been validated and sanitised. The $tableName argument and the column names should be defined by the calling logic; for instance a User model could be mapped to the user table, which has its column list mapped to the model's member fields.

public function InsertRange($tableName, $rows)
{
    // Get column list
    $columnList = array_keys($rows[0]);
    $numColumns = count($columnList);
    $columnListString = implode(",", $columnList);

    // Generate pdo param placeholders
    $placeHolders = array();

    foreach($rows as $row)
    {
        $temp = array();

        for($i = 0; $i < count($row); $i++)
            $temp[] = "?";

        $placeHolders[] = "(" . implode(",", $temp) . ")";
    }

    $placeHolders = implode(",", $placeHolders);

    // Construct the query
    $sql = "insert into $tableName ($columnListString) values $placeHolders";
    $stmt = $this->pdo->prepare($sql);

    $j = 1;
    foreach($rows as $row)
    {
        for($i = 0; $i < $numColumns; $i++)
        {
            $stmt->bindParam($j, $row[$columnList[$i]]);
            $j++;
        }
    }

    $stmt->execute();
}

For Eclipse, modify project.properties like this: (your path please)

android.library.reference.1=../../../../workspace/appcompat_v7_22

And remove android-support-v4.jar file in your project's libs folder.

Sometimes you can play with padding and margin top, add line-height, etc.

See fiddle.

Here column name must be decimal.

There are several timezones in operation here:

1. Java's Date classes (util and sql), which have implicit timezones of UTC
2. The timezone your JVM is running in, and
3. the default timezone of your database server.

All of these can be different. Hibernate/JPA has a severe design deficiency in that a user cannot easily ensure that timezone information is preserved in the database server (which allows reconstruction of correct times and dates in the JVM).

Without the ability to (easily) store timezone using JPA/Hibernate then information is lost and once information is lost it becomes expensive to construct it (if at all possible).

I would argue that it is better to always store timezone information (should be the default) and users should then have the optional ability to optimize the timezone away (although it only really affects display, there is still an implicit timezone in any date).

Sorry, this post doesn't provide a work-around (that's been answered elsewhere) but it is a rationalization of why always storing timezone information around is important. Unfortunately it seems many Computer Scientists and programming practitioners argue against the need for timezones simply because they don't appreciate the "loss of information" perspective and how that makes things like internationalization very difficult - which is very important these days with web sites accessible by clients and people in your organization as they move around the world.

In general your .h contains the class defition, which is all your data and all your method declarations. Like this in your case:

A2DD.h:

class A2DD
{
  private:
  int gx;
  int gy;

  public:
  A2DD(int x,int y);    
  int getSum();
};

And then your .cpp contains the implementations of the methods like this:

A2DD.cpp:

A2DD::A2DD(int x,int y)
{
  gx = x;
  gy = y;
}

int A2DD::getSum()
{
  return gx + gy;
}

Try with:

 git symbolic-ref --short -q HEAD

Or you try with git branch with --no-color force simple plain string the output:

 git branch  --no-color

With grep in regex mode(-E) you can check if exists the character '*':

 git branch  --no-color  | grep -E '^\*' 

The results its similar to:

* currentBranch

You can use the next options:

sed 's/\*[^a-z]*//g'
cut -d ' ' -f 2
awk '{print $2}'

for example:

 git branch  --no-color  | grep -E '^\*' | sed 's/\*[^a-z]*//g'
 git branch  --no-color  | grep -E '^\*' | sed cut -d ' ' -f 2
 git branch  --no-color  | grep -E '^\*' | awk '{print $2}'

if exists a error you cant use an default value:

  cmd || echo 'defualt value';

All into in a bash function:

function get_branch() {
      git branch --no-color | grep -E '^\*' | awk '{print $2}' \
        || echo "default_value"
      # or
      # git symbolic-ref --short -q HEAD || echo "default_value";
}

Use:

branch_name=`get_branch`;
echo $branch_name;

i founded this tool to auto generate wsdl to android code,

http://www.wsdl2code.com/Example.aspx

    Response response =  srv1.ServiceSample(req);
}

With all the method posted, there are problems recognizing when the user is scrolling up from the first element or down from the last. Here is another approach to detect scroll up/down:

        listView.setOnTouchListener(new View.OnTouchListener() {
            float height;
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int action = event.getAction();
                float height = event.getY();
                if(action == MotionEvent.ACTION_DOWN){
                    this.height = height;
                }else if(action == MotionEvent.ACTION_UP){
                    if(this.height < height){
                        Log.v(TAG, "Scrolled up");
                    }else if(this.height > height){
                        Log.v(TAG, "Scrolled down");
                    }
                }
                return false;
            }
        });

Here I can't see even a single correct answer for this question (in WinForms tag) and it's strange for such frequent question.

Items of a ListBox control may be DataRowView, Complex Objects, Anonymous types, primary types and other types. Underlying value of an item should be calculated base on ValueMember.

ListBox control has a GetItemText which helps you to get the item text regardless of the type of object you added as item. It really needs such GetItemValue method.

GetItemValue Extension Method

We can create GetItemValue Extension Method to get item value which works like GetItemText:

using System;
using System.Windows.Forms;
using System.ComponentModel;
public static class ListControlExtensions
{
    public static object GetItemValue(this ListControl list, object item)
    {
        if (item == null)
            throw new ArgumentNullException("item");

        if (string.IsNullOrEmpty(list.ValueMember))
            return item;

        var property = TypeDescriptor.GetProperties(item)[list.ValueMember];
        if (property == null)
            throw new ArgumentException(
                string.Format("item doesn't contain '{0}' property or column.",
                list.ValueMember));
        return property.GetValue(item);
    }
}

Using above method you don't need to worry about settings of ListBox and it will return expected Value for an item. It works with List<T>, Array, ArrayList, DataTable, List of Anonymous Types, list of primary types and all other lists which you can use as data source. Here is an example of usage:

//Gets underlying value at index 2 based on settings
this.listBox1.GetItemValue(this.listBox1.Items[2]);

Since we created the GetItemValue method as an extension method, when you want to use the method, don't forget to include the namespace which you put the class in.

This method is applicable on ComboBox and CheckedListBox too.

The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding

The part where we encode from Unicode/UTF-8 is

function utf8_to_b64( str ) {
   return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
   return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

This is one of the most used methods nowadays.

You can use the dig/host command to look up the MX records to see which mail server is handling mails for this domain.

On Linux you can do it as following for example:

$ host google.com
google.com has address 74.125.127.100
google.com has address 74.125.67.100
google.com has address 74.125.45.100
google.com mail is handled by 10 google.com.s9a2.psmtp.com.
google.com mail is handled by 10 smtp2.google.com.
google.com mail is handled by 10 google.com.s9a1.psmtp.com.
google.com mail is handled by 100 google.com.s9b2.psmtp.com.
google.com mail is handled by 10 smtp1.google.com.
google.com mail is handled by 100 google.com.s9b1.psmtp.com.

(as you can see, google has quite a lot of mail servers)

If you are working with windows, you might use nslookup (?) or try some web tool (e.g. that one) to display the same information.

Although that will only tell you the mail server for that domain. All other settings which are required can't be gathered that way. You might have to ask the provider.

Some IDEs highlight the code in heredoc strings automatically - which makes using heredoc for XML or HTML visually appealing.

I personally like it for longer parts of i.e. XML since I don't have to care about quoting quote characters and can simply paste the XML.

If you have to convert dates other than today to different timezones you have to deal with daylight savings. I wanted a solution that could be done without worrying about database version, without using stored functions and something that could easily be ported to Oracle.

I think Warren is on the right track with getting the correct dates for daylight time, but to make it more useful for multiple time zone and different rules for countries and even the rule that changed in the US between 2006 and 2007, here a variation on the above solution. Notice that this not only has us time zones, but also central Europe. Central Europe follow the last sunday of april and last sunday of october. You will also notice that the US in 2006 follows the old first sunday in april, last sunday in october rule.

This SQL code may look a little ugly, but just copy and paste it into SQL Server and try it. Notice there are 3 section for years, timezones and rules. If you want another year, just add it to the year union. Same for another time zone or rule.

For the rules, use 1, 2, 3 or L for first, second, third or last sunday. The date part gives the month and depending on the rule, the first day of the month or the last day of the month for rule type L.

In reply to Is there a specific reason?, here is one interesting application: breaking out of multiple levels of looping.

Here is how it works: the outer loop has a break at the end, so it would only be executed once. However, if the inner loop completes (finds no divisor), then it reaches the else statement and the outer break is never reached. This way, a break in the inner loop will break out of both loops, rather than just one.

for k in [2, 3, 5, 7, 11, 13, 17, 25]:
    for m in range(2, 10):
        if k == m:
            continue
        print 'trying %s %% %s' % (k, m)
        if k % m == 0:
            print 'found a divisor: %d %% %d; breaking out of loop' % (k, m)
            break
    else:
        continue
    print 'breaking another level of loop'
    break
else:
    print 'no divisor could be found!'

For both while and for loops, the else statement is executed at the end, unless break was used.

In most cases there are better ways to do this (wrapping it into a function or raising an exception), but this works!

Removing duplicates after pushing

If you already have an array containing duplicates, transform the array of objects into an array of strings, and then use the Set() function to eliminate duplicates:

// Declaring an array of objects containing duplicate objects
let arrayOfObjects = [{name: "tom", text: "tasty"}, {name: "tom", text: "tasty"}];

// Transforming array of objects into array of strings
let arrayOfStrings = arrayOfObjects.map(obj => JSON.stringify(obj));

// Creating a new set, Set() returns unique values by definition
let uniqueSet = new Set(arrayOfStrings);

// Transforming set into array and reversing strings to objects
let uniqueArrayOfObjects = [...uniqueSet].map(elem => JSON.parse(elem));

console.log(uniqueArrayOfObjects);
// [{name: "tom", text: "tasty"}]

Checking before pushing

If you don't have duplicates so far and you want to check for duplicates before pushing a new element:

// Declaring an array of objects without duplicates
let arrayOfObjects = [{name: "tom", text: "tasty"}];

// Transforming array of objects into array of strings
let arrayOfStrings = arrayOfObjects.map(obj => JSON.stringify(obj));

// Declaring new element as an example
let newElem = {name: "tom", text: "tasty"};

// Stringifying new element
let newElemString = JSON.stringify(newElem);

// At this point, check if the string is duplicated and add it to array
!arrayOfStrings.includes(newElemString) && arrayOfObjects.push(newElem);

console.log(arrayOfObjects);
// [{name: "tom", text: "tasty"}]

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)
        .where(predicateResult);

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)
        .getResultList();  

CREATE TABLE dbo.OwnerType
(
    ID int NOT NULL,
    Name varchar(50) NULL
)

insert into OwnerType (Name) values ('User');
insert into OwnerType (Name) values ('Group');

I think that would be the most general way to represent what you want instead of using a flag.

I know this question is a bit old, but I'd use a jQuery template and a $.ajax call:

ASPX:
<select id="mySelect" name="mySelect>
    <option value="0">-select-</option>
</select>
<script id="mySelectTemplate" type="text/x-jquery-tmpl">
    <option value="${CityId}">${CityName}</option>
</script>

JS:
$.ajax({ 
    url: location.pathname + '/GetCities', 
    type: 'POST', 
    contentType: 'application/json; charset=utf-8', 
    dataType: 'json', 
    success: function (response) { 
        $('#mySelectTemplate').tmpl(response.d).appendTo('#mySelect'); 
    } 
});

In addition to the above you'll need a web method (GetCities) that returns a list of objects that include the data elements you're using in your template. I often use Entity Framework and my web method will call a manager class that is getting values from the database using linq. By doing that you can have your input save to the database and refreshing your select list is as simple as calling the databind in JS in the success of your save.

Here is a version that works well in September 2020 using fetch and https://worldtimeapi.org/api

fetch("https://worldtimeapi.org/api/ip")
  .then(response => response.json())
  .then(data => console.log(data.timezone,data.datetime,data.dst));

Since not all versions of jQuery are created equal, you may run into the same issue I did which means calling $("#item").removeClass(); does not actually remove the class. (Probably a bug)

A more reliable method is to simply use raw JavaScript and remove the class attribute altogether.

document.getElementById("item").removeAttribute("class");

I thought about this very often during my PhD (in computer science). I came up with multiple solutions, depending on the ability to distinguish socks and thus find correct pairs as fast as possible.

Suppose the cost of looking at socks and memorizing their distinctive patterns is negligible (e). Then the best solution is simply to throw all socks on a table. This involves those steps:

1. Throw all socks on a table (1) and create a hashmap {pattern: position} (e)
2. While there are remaining socks (n/2):
   1. Pick up one random sock (1)
   2. Find position of corresponding sock (e)
   3. Retrieve sock (1) and store pair

This is indeed the fastest possibility and is executed in n + 1 = O(n) complexity. But it supposes that you perfectly remember all patterns... In practice, this is not the case, and my personal experience is that you sometimes don't find the matching pair at first attempt:

1. Throw all socks on a table (1)
2. While there are remaining socks (n/2):
   1. Pick up one random sock (1)
   2. while it is not paired (1/P):
      1. Find sock with similar pattern
      2. Take sock and compare both (1)
      3. If ok, store pair

This now depends on our ability to find matching pairs. This is particularly true if you have dark/grey pairs or white sports socks that often have very similar patterns! Let's admit that you have a probability of P of finding the corresponding sock. You'll need, on average, 1/P tries before finding the corresponding sock to form a pair. The overall complexity is 1 + (n/2) * (1 + 1/P) = O(n).

Both are linear in the number of socks and are very similar solutions. Let's slightly modify the problem and admit you have multiple pairs of similar socks in the set, and that it is easy to store multiple pairs of socks in one move (1+e). For K distinct patterns, you may implement:

1. For each sock (n):
   1. Pick up one random sock (1)
   2. Put it on its pattern's cluster
2. For each cluster (K):
   1. Take cluster and store pairs of socks (1+e)

The overall complexity becomes n+K = O(n). It is still linear, but choosing the correct algorithm may now greatly depend on the values of P and K! But one may object again that you may have difficulties to find (or create) cluster for each sock.

Besides, you may also loose time by looking on websites what is the best algorithm and proposing your own solution :)

foreach(var newAnimal in NewAnimals)
    Animals.Add(newAnimal.Key,newAnimal.Value)

Note: this throws an exception on a duplicate key.

Or if you really want to go the extension method route(I wouldn't), then you could define a general AddRange extension method that works on any ICollection<T>, and not just on Dictionary<TKey,TValue>.

public static void AddRange<T>(this ICollection<T> target, IEnumerable<T> source)
{
    if(target==null)
      throw new ArgumentNullException(nameof(target));
    if(source==null)
      throw new ArgumentNullException(nameof(source));
    foreach(var element in source)
        target.Add(element);
}

(throws on duplicate keys for dictionaries)

You use the available API of JTable and do not try to mess with the colors.

Some selection methods are available directly on the JTable (like the setRowSelectionInterval). If you want to have access to all selection-related logic, the selection model is the place to start looking

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

SQL Server 2012+ (for both month and day):

SELECT FORMAT(GetDate(),'MMdd')

If you decide you want the year too, use:

SELECT FORMAT(GetDate(),'yyyyMMdd')

below the generic function for window.open pass values using POST:

function windowOpenInPost(actionUrl,windowName, windowFeatures, keyParams, valueParams) 
{
    var mapForm = document.createElement("form");
    var milliseconds = new Date().getTime();
    windowName = windowName+milliseconds;
    mapForm.target = windowName;
    mapForm.method = "POST";
    mapForm.action = actionUrl;
    if (keyParams && valueParams && (keyParams.length == valueParams.length)){
        for (var i = 0; i < keyParams.length; i++){
        var mapInput = document.createElement("input");
            mapInput.type = "hidden";
            mapInput.name = keyParams[i];
            mapInput.value = valueParams[i];
            mapForm.appendChild(mapInput);

        }
        document.body.appendChild(mapForm);
    }


    map = window.open('', windowName, windowFeatures);
if (map) {
    mapForm.submit();
} else {
    alert('You must allow popups for this map to work.');
}}

Prerequisites :

install antiword : sudo apt-get install antiword

install docx : pip install docx

A simple (and maybe simplistic) answer to the question is the content of $x numeric is the following:

if ($x  eq  $x+0) { .... }

It does a textual comparison of the original $x with the $x converted to a numeric value.

1. Don't use quotation in a field name or table name inside the query.

2. After fetching an object you need to access object attributes/properties (in your case id) by attributes/properties name.

One note: please use mysqli_* or PDO since mysql_* deprecated. Here it is using mysqli:

session_start();
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = new mysqli('localhost', 'username', 'password', 'db_name');
$link->set_charset('utf8mb4'); // always set the charset
$name = $_GET["username"];
$stmt = $link->prepare("SELECT id FROM Users WHERE username=? limit 1");
$stmt->bind_param('s', $name);
$stmt->execute();
$result = $stmt->get_result();
$value = $result->fetch_object();
$_SESSION['myid'] = $value->id;

Bonus tips: Use limit 1 for this type of scenario, it will save execution time :)

This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ?+RETURN to CTRL+SHIFT+RETURN.

Some APIs want you to supply the appropriate "Accept" header in the request to get the wanted response type.

For example if an API can return data in XML and JSON and you want the JSON result, you would need to set the HttpWebRequest.Accept property to "application/json".

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

By default, Visual Studio defines DEBUG if project is compiled in Debug mode and doesn't define it if it's in Release mode. RELEASE is not defined in Release mode by default. Use something like this:

#if DEBUG
  // debug stuff goes here
#else
  // release stuff goes here
#endif

If you want to do something only in release mode:

#if !DEBUG
  // release...
#endif

Also, it's worth pointing out that you can use [Conditional("DEBUG")] attribute on methods that return void to have them only executed if a certain symbol is defined. The compiler would remove all calls to those methods if the symbol is not defined:

[Conditional("DEBUG")]
void PrintLog() {
    Console.WriteLine("Debug info");
}

void Test() {
    PrintLog();
}

I had similar problems as well. I put the following line of code in the head of my layout file and all seems to be fine.

<meta http-equiv="X-UA-Compatible" content="IE=9">

1. try telnet 3306. If it doesn't open connection, either there is a firewall setting or the server isn't listening (or doesn't work).

2. run netstat -an on server to see if server is up.

3. It's possible that you don't allow remote connections.

   See http://www.cyberciti.biz/tips/how-do-i-enable-remote-access-to-mysql-database-server.html

Obviously, the syntax are completely different (Groovy is closest to Java), but I suppose that is not what you are asking for.

If you are interested in using them to script a Java application, Scala is probably not a good choice, as there is no easy way to evaluate it from Java, whereas Groovy is especially suited for that purpose.

I solved it in XAMPP by uncommenting ;extension=php_openssl.dll in /apache/bin/php.ini despite phpinfo() telling me /php/php.ini was the loaded ini file.

EDIT: I guess Ezra answer is the best solution directly adding the extension line to the appropriate ini file.

Map<K,V> is an interface, HashMap<K,V> is a class that implements Map.

you can do

Map<Key,Value> map = new HashMap<Key,Value>();

Here you have a link to the documentation of each one: Map, HashMap.

By dynamically allocating a Movie object with new Movie(), you get a pointer to the new object. You do not need a second vector for the movies, just store the pointers and you can access them. Like Brian wrote, the vector would be defined as

std::vector<Movie *> movies

But be aware that the vector will not delete your objects afterwards, which will result in a memory leak. It probably doesn't matter for your homework, but normally you should delete all pointers when you don't need them anymore.

$items = array();
foreach ($haystacks as $haystack) {
    if (preg_match($pattern, $haystack, $matches)
        $items[] = $matches[1];
}

It's quite easy, actually. You can use the System.IO.Directory class in conjunction with System.IO.Path. Something like (using LINQ makes it even easier):

var allFilenames = Directory.EnumerateFiles(path).Select(p => Path.GetFileName(p));

// Get all filenames that have a .txt extension, excluding the extension
var candidates = allFilenames.Where(fn => Path.GetExtension(fn) == ".txt")
                             .Select(fn => Path.GetFileNameWithoutExtension(fn));

There are many variations on this technique too, of course. Some of the other answers are simpler if your filter is simpler. This one has the advantage of the delayed enumeration (if that matters) and more flexible filtering at the expense of more code.

Sadly the other posters are correct that you're ...actually as corrected by kRON, you are ok with your IE7 and a strict doc, but most of us with IE6 requirements are reduced to JS or class references for this, but it is a CSS2 property, just one without sufficient support from IE^h^h browsers.

Out of completeness, the type selector is - similar to xpath - of the form [attribute=value] but many interesting variants exist. It will be quite powerful when it's available, good thing to keep in your head for IE8.

• w3 reference

• browser support reference

You can use the ruby method:

:root_url

which will get the full path with base url:

localhost:3000/bla

Since the question mentions VirtualBox, this one works currently:

VBoxManage convertfromraw imagefile.dd vmdkname.vmdk --format VMDK

Run it without arguments for a few interesting details (notably the --variant flag):

VBoxManage convertfromraw

Or you can use GSON [https://code.google.com/p/google-gson/], where these null fields will be automatically removed.

SampleDTO.java

        Gson objGson = new Gson();
        System.out.println(objGson.toJson(objSampleDTO));

I used gson-2.2.4

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

If you identify a page that takes time to load, use SharePoint's Developer Dashboard to see which component takes time.

There's a workaround for IE - use inline SVG and set pointer-events="none" in SVG. See my answer in How to make Internet Explorer emulate pointer-events:none?

You can try something like

SELECT  e.EntityId, 
        e.EntityName, 
        CASE 
            WHEN ep.EntityId IS NULL THEN 'False' 
            ELSE 'TRUE' 
        END AS HasProfile 
FROM    Entities e LEFT JOIN 
        EntityProfiles ep ON e.EntityID = ep.EntityID

Or

SELECT e.EntityId, 
        e.EntityName, 
        CASE 
            WHEN e.EntityProfile IS NULL THEN 'False' 
            ELSE 'TRUE' 
        END AS HasProfile 

FROM    Entities e

As noted in this linked question, setting listeners for viewHolders should be done in onCreateViewHolder. That said, the implementation below was originally aimed at multiple selection, but I threw a hack in the snippet to force single selection.(*1)

// an array of selected items (Integer indices) 
private final ArrayList<Integer> selected = new ArrayList<>();

// items coming into view
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    // each time an item comes into view, its position is checked
    // against "selected" indices
    if (!selected.contains(position)){
        // view not selected
        holder.parent.setBackgroundColor(Color.LTGRAY);
    }
    else
        // view is selected
        holder.parent.setBackgroundColor(Color.CYAN);
}

// selecting items
@Override
public boolean onLongClick(View v) {
        
        // select (set color) immediately.
        v.setBackgroundColor(Color.CYAN);

        // (*1)
        // forcing single selection here...
        if (selected.isEmpty()){
            selected.add(position); // (done - see note)
        }else {
            int oldSelected = selected.get(0);
            selected.clear(); // (*1)... and here.
            selected.add(position);
            // note: We do not notify that an item has been selected
            // because that work is done here.  We instead send
            // notifications for items which have been deselected.
            notifyItemChanged(oldSelected);
        }
        return false;
}

One sneaky way you could do it although it does require the use of (the much hated) eval().

var sum = eval(elmt.join('+')), avg = sum / elmt.length;
document.write("The sum of all the elements is: " + sum + " The average of all the elements is: " + avg + "<br/>");

Just thought I'd post this as one of those 'outside the box' options. You never know, the slyness might grant you (or taketh away) a point.

For the primitive types, the 'final static' will be a proper declaration to declare a constant. A non-static final variable makes sense when it is a constant reference to an object. In this case each instance can contain its own reference, as shown in JLS 4.5.4.

See Pavel's response for the correct answer.

The way that the language manages lexical scope creates issues with including both goto and continue. For example,

local a=0
repeat 
    if f() then
        a=1 --change outer a
    end
    local a=f() -- inner a
until a==0 -- test inner a

The declaration of local a inside the loop body masks the outer variable named a, and the scope of that local extends across the condition of the until statement so the condition is testing the innermost a.

If continue existed, it would have to be restricted semantically to be only valid after all of the variables used in the condition have come into scope. This is a difficult condition to document to the user and enforce in the compiler. Various proposals around this issue have been discussed, including the simple answer of disallowing continue with the repeat ... until style of loop. So far, none have had a sufficiently compelling use case to get them included in the language.

The work around is generally to invert the condition that would cause a continue to be executed, and collect the rest of the loop body under that condition. So, the following loop

-- not valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if isstring(k) then continue end
  -- do something to t[k] when k is not a string
end

could be written

-- valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if not isstring(k) then 
    -- do something to t[k] when k is not a string
  end
end

It is clear enough, and usually not a burden unless you have a series of elaborate culls that control the loop operation.

You could also wrap the transaction up into it's own stored procedure and handle it that way instead of doing transactions in C# itself.

Another good approach not mentioned in other posts is to use PropertyOverrideConfigurer in case you just want to override properties of some beans.

For example if you want to override the datasource for testing (i.e. use an in-memory database) in another xml config, you just need to use <context:property-override ..."/> in new config and a .properties file containing key-values taking the format beanName.property=newvalue overriding the main props.

application-mainConfig.xml:

<bean id="dataSource" 
    class="org.apache.commons.dbcp.BasicDataSource" 
    p:driverClassName="org.postgresql.Driver"
    p:url="jdbc:postgresql://localhost:5432/MyAppDB" 
    p:username="myusername" 
    p:password="mypassword"
    destroy-method="close" />

application-testConfig.xml:

<import resource="classpath:path/to/file/application-mainConfig.xml"/>

<!-- override bean props -->
<context:property-override location="classpath:path/to/file/beanOverride.properties"/>

beanOverride.properties:

dataSource.driverClassName=org.h2.Driver
dataSource.url=jdbc:h2:mem:MyTestDB

Despite NylonSmile's answer, which is "sort of" correct.. I was unable to overwrite files, in this manner..

Obviously, be careful with this...

The lambda you pass to Where can include any normal C# code, for example the && operator:

.Where(l => l.Title != string.Empty && l.InternalName != string.Empty)

    from p in PriceLog
    group p by p.LogDateTime.ToString("MMM") into g
    select new 
    { 
        LogDate = g.Key.ToString("MMM yyyy"),
        GoldPrice = (int)dateGroup.Average(p => p.GoldPrice), 
        SilverPrice = (int)dateGroup.Average(p => p.SilverPrice) 
    }

We use this method (creating a bare repository in Dropbox) on a share folder.

A small group of developers can pull from that bare synced repository and create a local clone. Once the unit of work is done, we push back to origin.

One thing I'm missing is a good way to have an e-mail sent with the change-set information once a push to origin occurs. We are using Google Wave to manually keep track of changes.

Create an image to use as background with Photoshop or gimp and name it myimage. Then, add this method to your tableViewController class:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    UIImage *cellImage = [UIImage imageNamed:@"myimage.png"];//myimage is a 20x50 px with  gradient  color created with gimp
    UIImageView *cellView = [[UIImageView alloc] initWithImage:cellImage];
    cellView.contentMode = UIContentViewModeScaleToFill;
    cell.backgroundView = cellView;
    //set the background label to clear
    cell.titleLabel.backgroundColor= [UIColor clearColor];
}

This will work also if you have set the UITableView to custom in attribute inspector.

with pure JavaScript: (although Object.entries is ES7, Object.assign is ES6; but equivalent ES5 uses Object.keys only should be also doable); also notice v != null checks for both null and undefined;

> var d = { a:undefined, b:2, c:0, d:undefined, e: null, f: 0.3, s: "", t: false };
undefined
> Object.entries(d)
    .filter(([ k, v ]) => (v != null))
    .reduce((acc, [k, v]) => Object.assign(acc, {[k]: v}), {})
{ b: 2, c: 0, f: 0.3, s: '', t: false }

Edit: this below is the version with ES5 Object.keys only: but generally with ES7 in Node v8 is pretty much enjoyable ;-)

> Object.keys(d)
    .filter(function(k) { return d[k] != null; })
    .reduce(function(acc, k) { acc[k] = d[k]; return acc; }, {});
{ b: 2, c: 0, f: 0.3, s: '', t: false }

Update in October 2017: with Node v8 (since v8.3 or so) now it has object spreading construct:

> var d = { a:undefined, b:2, c:0, d:undefined,
    e: null, f: -0.0, s: "", t: false, inf: +Infinity, nan: NaN };
undefined
> Object.entries(d)
    .filter(([ k, v ]) => (v != null))
    .reduce((acc, [k, v]) => ({...acc, [k]: v}), {})
{ b: 2, c: 0, f: -0, s: '', t: false, inf: Infinity, nan: NaN }

or within one reduce only:

> Object.entries(d)
   .reduce((acc, [k, v]) => (v==null ? acc : {...acc, [k]: v}), {})
{ b: 2, c: 0, f: -0, s: '', t: false, inf: Infinity, nan: NaN }

Update: someone want recursive? isn't that hard either, just need an additional check of isObject, and recursively call itself:

> function isObject(o) {
    return Object.prototype.toString.call(o) === "[object Object]"; }
undefined
> function dropNullUndefined(d) {
    return Object.entries(d)
      .reduce((acc, [k, v]) => (
        v == null ? acc :
         {...acc, [k]: (isObject(v) ? dropNullUndefined(v) : v) }
      ), {});
  }
> dropNullUndefined({a: 3, b:null})
{ a: 3 }
> dropNullUndefined({a: 3, b:null, c: { d: 0, e: undefined }})
{ a: 3, c: { d: 0 } }

my conclusion: if pure Javascript can do, I would avoid any third party library dependencies:

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

I've been struggling with this too. On the surface it seems that the above solutions should work. However, the django architecture requires that each html file has its own rendered variables (that is, {{contact}} is rendered to contact.html, while {{posts}} goes to e.g. index.html and so on). On the other hand, <script> tags appear after the {%endblock%} in base.html from which contact.html and index.html inherit. This basically means that any solution including

<script type="text/javascript">
    var myVar = "{{ myVar }}"
</script>

is bound to fail, because the variable and the script cannot co-exist in the same file.

The simple solution I eventually came up with, and worked for me, was to simply wrap the variable with a tag with id and later refer to it in the js file, like so:

// index.html
<div id="myvar">{{ myVar }}</div>

and then:

// somecode.js
var someVar = document.getElementById("myvar").innerHTML;

and just include <script src="static/js/somecode.js"></script> in base.html as usual. Of course this is only about getting the content. Regarding security, just follow the other answers.

You need to set the width of the container (auto won't work):

#container {
    width: 640px; /* Can be in percentage also. */
    height: auto;
    margin: 0 auto;
    padding: 10px;
    position: relative;
}

The CSS reference by MDN explains it all.

Another way to do this in AngularJS is to use a Grid.

The advantage with grids is that the row sorting behavior you are looking for is included by default.

The functionality is well encapsulated. You don't need to add ng-click attributes, or use scope variables to maintain state:

    <body ng-controller="MyCtrl">
        <div class="gridStyle" ng-grid="gridOptions"></div>
    </body>

You just add the grid options to your controller:

  $scope.gridOptions = {
    data: 'myData.employees',
    columnDefs: [{
      field: 'firstName',
      displayName: 'First Name'
    }, {
      field: 'lastName',
      displayName: 'Last Name'
    }, {
      field: 'age',
      displayName: 'Age'
    }]
  };

Also worth noting that if you have two factor authentication enabled, you'll need to setup an application specific password to use in place of your email account's password.

You can generate an application specific password by following these instructions: https://support.google.com/accounts/answer/185833

Then set $mail->Password to your application specific password.

When you run the Windows Command Prompt, and type in python, it starts the Python interpreter.

Typing it again tries to interpret python as a variable, which doesn't exist and thus won't work:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line

C:\Users\USER>

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python is interpreted as a variable, which you have not defined.

I am using Server version: 5.7.11-log MySQL Community Server (GPL)

Now we will solve this in a simple way.

I have created a table named "datetable"

mysql> describe datetable;
+---------+---------+------+-----+---------+-------+
| Field   | Type    | Null | Key | Default | Extra |
+---------+---------+------+-----+---------+-------+
| colid   | int(11) | NO   | PRI | NULL    |       |
| coldate | date    | YES  |     | NULL    |       |
+---------+---------+------+-----+---------+-------+
2 rows in set (0.00 sec)

now, wee will see the inserted records within.

mysql> select * from datetable;
+-------+------------+
| colid | coldate    |
+-------+------------+
|   101 | 2015-01-01 |
|   102 | 2015-05-01 |
|   103 | 2016-01-01 |
+-------+------------+
3 rows in set (0.00 sec)

and here our query to fetch records within two dates rather than those dates.

mysql> select * from datetable where coldate > '2015-01-01' and coldate < '2016-01-01';
+-------+------------+
| colid | coldate    |
+-------+------------+
|   102 | 2015-05-01 |
+-------+------------+
1 row in set (0.00 sec)

hope this would help many ones.

The only time you should worry your users about something that happened in the code is if there is something they can or need to do to avoid the issue. If they can change data on a form, push a button or change a application setting in order to avoid the issue then let them know. But warnings or errors that the user has no ability to avoid just makes them lose confidence in your product.

Exceptions and Logs are for you, the developer, not your end user. Understanding the right thing to do when you catch each exception is far better than just applying some golden rule or rely on an application-wide safety net.

Mindless coding is the ONLY kind of wrong coding. The fact that you feel there is something better that can be done in those situations shows that you are invested in good coding, but avoid trying to stamp some generic rule in these situations and understand the reason for something to throw in the first place and what you can do to recover from it.

My Intellij version is 13.4.1

Yet Another Snippet

Referred main as the main function and exit_gracefully as the CTRL + c handler

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        pass
    finally:
        exit_gracefully()

You use this signature: (in c#) static void Main(string[] args)

This article may help to explain the role of the main function in programming as well: http://en.wikipedia.org/wiki/Main_function_(programming)

Here is a little example for you:

class Program
{
    static void Main(string[] args)
    {
        bool doSomething = false;

        if (args.Length > 0 && args[0].Equals("doSomething"))
            doSomething = true;

        if (doSomething) Console.WriteLine("Commandline parameter called");
    }
}

You need to initialize the list first:

protected List<string> list = new List<string>();

For mysql you have limit, you can fire query as :

SELECT * FROM table limit 100` -- get 1st 100 records
SELECT * FROM table limit 100, 200` -- get 200 records beginning with row 101

For Oracle you can use rownum

See mysql select syntax and usage for limit here.

For SQLite, you have limit, offset. I haven't used SQLite but I checked it on SQLite Documentation. Check example for SQLite here.

Probably you want something like:

firstline = True
for row in kidfile:
    if firstline:    #skip first line
        firstline = False
        continue
    # parse the line

An other way to achive the same result is calling readline before the loop:

kidfile.readline()   # skip the first line
for row in kidfile:
    #parse the line

There is no if-else, just if.

<c:if test="${user.age ge 40}">
 You are over the hill.
</c:if>

Optionally you can use choose-when:

<c:choose>
  <c:when test="${a boolean expr}">
    do something
  </c:when>
  <c:when test="${another boolean expr}">
    do something else
  </c:when>
  <c:otherwise>
    do this when nothing else is true
  </c:otherwise>
</c:choose>

instead of using the brackets use the object operator for example my array based on database object is created like this in a class called DB:

class DB {
private static $_instance = null;
private $_pdo,
        $_query, 
        $_error = false,
        $_results,
        $_count = 0;



private function __construct() {
    try{
        $this->_pdo = new PDO('mysql:host=' . Config::get('mysql/host') .';dbname=' . Config::get('mysql/db') , Config::get('mysql/username') ,Config::get('mysql/password') );


    } catch(PDOException $e) {
        $this->_error = true;
        $newsMessage = 'Sorry.  Database is off line';
        $pagetitle = 'Teknikal Tim - Database Error';
        $pagedescription = 'Teknikal Tim Database Error page';
        include_once 'dbdown.html.php';
        exit;
    }
    $headerinc = 'header.html.php';
}

public static function getInstance() {
    if(!isset(self::$_instance)) {
        self::$_instance = new DB();
    }

    return self::$_instance;

}


    public function query($sql, $params = array()) {
    $this->_error = false;
    if($this->_query = $this->_pdo->prepare($sql)) {
    $x = 1;
        if(count($params)) {
        foreach($params as $param){
            $this->_query->bindValue($x, $param);
            $x++;
            }
        }
    }
    if($this->_query->execute()) {

        $this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
        $this->_count = $this->_query->rowCount();

    }

    else{
        $this->_error = true;
    }

    return $this;
}

public function action($action, $table, $where = array()) {
    if(count($where) ===3) {
        $operators = array('=', '>', '<', '>=', '<=');

        $field      = $where[0];
        $operator   = $where[1];
        $value      = $where[2];

        if(in_array($operator, $operators)) {
            $sql = "{$action} FROM {$table} WHERE {$field} = ?";

            if(!$this->query($sql, array($value))->error()) {
            return $this;
            }
        }

    }
    return false;
}

    public function get($table, $where) {
    return $this->action('SELECT *', $table, $where);

public function results() {
    return $this->_results;
}

public function first() {
    return $this->_results[0];
}

public function count() {
    return $this->_count;
}

}

to access the information I use this code on the controller script:

<?php
$pagetitle = 'Teknikal Tim - Service Call Reservation';
$pagedescription = 'Teknikal Tim Sevice Call Reservation Page';
require_once $_SERVER['DOCUMENT_ROOT'] .'/core/init.php';
$newsMessage = 'temp message';

$servicecallsdb = DB::getInstance()->get('tt_service_calls', array('UserID',
 '=','$_SESSION['UserID']));

if(!$servicecallsdb) {
// $servicecalls[] = array('ID'=>'','ServiceCallDescription'=>'No Service Calls');
} else {
$servicecalls = $servicecallsdb->results();
}
include 'servicecalls.html.php';



?>

then to display the information I check to see if servicecalls has been set and has a count greater than 0 remember it's not an array I am referencing so I access the records with the object operator "->" like this:

<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/header.html.php';?>
<!--Main content-->
<div id="mainholder"> <!-- div so that page footer can have a minum height from the
  header -->
<h1><?php if(isset($pagetitle)) htmlout($pagetitle);?></h1>
<br>
<br>
<article>
    <h2></h2>
</article>
<?php
if (isset($servicecalls)) {
if (count ($servicecalls) > 0){
     foreach ($servicecalls as $servicecall) {
        echo '<a href="/servicecalls/?servicecall=' .$servicecall->ID .'">'
  .$servicecall->ServiceCallDescription .'</a>';
    }
}else echo 'No service Calls';

}

?>
<a href="/servicecalls/?new=true">Raise New Service Call</a>
</div> <!-- Main content end-->
<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/footer.html.php'; ?>

You simply call

Blog::all();

//example usage.
$posts = Blog::all();

$posts->each(function($post) // foreach($posts as $post) { }
{
    //do something
}

from anywhere in your application.

Reading the documentation will help a lot.

Since it has not been mentioned just for completion. The good ol' filter to filter your to be filtered elements.

Functional programming ftw.

####### Set Up #######
class X:

    def __init__(self, val):
        self.val = val

elem = 5

my_unfiltered_list = [X(1), X(2), X(3), X(4), X(5), X(5), X(6)]

####### Set Up #######

### Filter one liner ### filter(lambda x: condition(x), some_list)
my_filter_iter = filter(lambda x: x.val == elem, my_unfiltered_list)
### Returns a flippin' iterator at least in Python 3.5 and that's what I'm on

print(next(my_filter_iter).val)
print(next(my_filter_iter).val)
print(next(my_filter_iter).val)

### [1, 2, 3, 4, 5, 5, 6] Will Return: ###
# 5
# 5
# Traceback (most recent call last):
#   File "C:\Users\mousavin\workspace\Scripts\test.py", line 22, in <module>
#     print(next(my_filter_iter).value)
# StopIteration


# You can do that None stuff or whatever at this point, if you don't like exceptions.

I know that generally in python list comprehensions are preferred or at least that is what I read, but I don't see the issue to be honest. Of course Python is not an FP language, but Map / Reduce / Filter are perfectly readable and are the most standard of standard use cases in functional programming.

So there you go. Know thy functional programming.

filter condition list

It won't get any easier than this:

next(filter(lambda x: x.val == value,  my_unfiltered_list)) # Optionally: next(..., None) or some other default value to prevent Exceptions

Object Catalog View : sys.default_constraints

The information schema views INFORMATION_SCHEMA are ANSI-compliant, but the default constraints aren't a part of ISO standard. Microsoft SQL Server provides system catalog views for getting information about SQL Server object metadata.

sys.default_constraints system catalog view used to getting the information about default constraints.

SELECT so.object_id TableName,
       ss.name AS TableSchema,
       cc.name AS Name,
       cc.object_id AS ObjectID,              
       sc.name AS ColumnName,
       cc.parent_column_id AS ColumnID,
       cc.definition AS Defination,
       CONVERT(BIT,
               CASE cc.is_system_named
                   WHEN 1
                   THEN 1
                   ELSE 0
               END) AS IsSystemNamed,
       cc.create_date AS CreationDate,
       cc.modify_date AS LastModifiednDate
FROM sys.default_constraints cc WITH (NOLOCK)
     INNER JOIN sys.objects so WITH (NOLOCK) ON so.object_id = cc.parent_object_id
     LEFT JOIN sys.schemas ss WITH (NOLOCK) ON ss.schema_id = so.schema_id
     LEFT JOIN sys.columns sc WITH (NOLOCK) ON sc.column_id = cc.parent_column_id
                                               AND sc.object_id = cc.parent_object_id
ORDER BY so.name,
         cc.name;

You could do something like this

String[] myStrings = { "One", "Two", "Three" };

or in expression

functionCall(new String[] { "One", "Two", "Three" });

or

String myStrings[];
myStrings = new String[] { "One", "Two", "Three" };

An overlay is, simply put, a div that stays fixed on the screen (no matter if you scroll) and has some sort of opacity.

This will be your CSS for cross browser opacity of 0.5:

#overlay {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-color: #000;
    filter:alpha(opacity=50);
    -moz-opacity:0.5;
    -khtml-opacity: 0.5;
    opacity: 0.5;
    z-index: 10000;
}

This will be your jQuery code (no UI needed). You're just going to create a new element with the ID #overlay. Creating and destroying the DIV should be all you need.

var overlay = jQuery('<div id="overlay"> </div>');
overlay.appendTo(document.body)

For performance reasons you might wanna have the DIV hidden and setting the display to block and none as you need it or not.

Hope it helps!

Edit: As @Vitaly so well put it, be sure to check your DocType. Read more on the comments on his findings..

Note for MySQL 8 it's different

If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b is a power of two, a % b == a & (b - 1).

For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63, because 63 is 111111 in binary.

The masked, higher digits are not of interest to us. Try it out!

Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!

The correct options are (in increasing order of recommendation):

# Single POSIX test command with -o operator (not recommended anymore).
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 -o "$stats" -eq 0 ]

# Two POSIX test commands joined in a list with ||.
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 ] || [ "$stats" -eq 0 ]

# Two bash conditional expressions joined in a list with ||.
while [[ $stats -gt 300 ]] || [[ $stats -eq 0 ]]

# A single bash conditional expression with the || operator.
while [[ $stats -gt 300 || $stats -eq 0 ]]

# Two bash arithmetic expressions joined in a list with ||.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 )) || (( stats == 0 ))

# And finally, a single bash arithmetic expression with the || operator.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 || stats == 0 ))

Some notes:

1. Quoting the parameter expansions inside [[ ... ]] and ((...)) is optional; if the variable is not set, -gt and -eq will assume a value of 0.

2. Using $ is optional inside (( ... )), but using it can help avoid unintentional errors. If stats isn't set, then (( stats > 300 )) will assume stats == 0, but (( $stats > 300 )) will produce a syntax error.

Make sure your modal is not placed in a container, try to add the !important annotation if it's not changing the width from the original one.

yes you can. Android kitkat boosts of this functionality here

You could try something like this:

...Binding="{Binding RelativeSource={RelativeSource FindAncestor, 
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

Alternatively to information_schema it is possible to use pg_tables:

select * from pg_tables where schemaname='public';

I can't speak to the use of it, though. Not used it myself (yet)

In my case, when I'm in an activity that extends from AppCompatActivity, it did not work(Activity) getApplicationContext (), I just putthis in its place.

1. utf8_decode $j_decoded = utf8_decode(json_decode($j_encoded)); EDIT or to be more correct $j_encoded = json_encode($j_encoded); $j_decoded = json_decode($j_encoded); no need for en/decoding utf8
2. <meta charset="utf-8" />

If you have ListView in any Parent panel (ListView dock fill), you can use simply method...

private void ListViewHeaderWidth() {
        int HeaderWidth = (listViewInfo.Parent.Width - 2) / listViewInfo.Columns.Count;
        foreach (ColumnHeader header in listViewInfo.Columns)
        {
            header.Width = HeaderWidth;
        }
    }

check out this.

<activity android:name=".Calculator"
    android:windowSoftInputMode="stateHidden|adjustResize" 
    android:theme="@android:style/Theme.Black.NoTitleBar">
</activity>

You've specifically mentioned a "variable-length array" in your question, so neither of the existing two answers (as I write this) are quite right.

Java doesn't have any concept of a "variable-length array", but it does have Collections, which serve in this capacity. Any collection (technically any "Iterable", a supertype of Collections) can be looped over as simply as this:

Collection<Thing> things = ...;
for (Thing t : things) {
  System.out.println(t);
}

EDIT: it's possible I misunderstood what he meant by 'variable-length'. He might have just meant it's a fixed length but not every instance is the same fixed length. In which case the existing answers would be fine. I'm not sure what was meant.

Somehow all these solutions didn't work for me. There is clearly an IE bug in flex-direction:column.

I only got it working after removing flex-direction:

flex-wrap: wrap;
align-items: center;
align-content: center;

I have slightly improved answer, which handles extended CSS definitions like:

background-image: url(http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png), -webkit-linear-gradient(top, rgb(81, 127, 164), rgb(48, 96, 136))

JavaScript code:

var bg = $("div").css("background-image")
bg = bg.replace(/.*\s?url\([\'\"]?/, '').replace(/[\'\"]?\).*/, '')

Result:

"http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png"

Add to your ~/.bashrc:

pyclean () {
        find . -type f -name "*.py[co]" -delete
        find . -type d -name "__pycache__" -delete
}

This removes all .pyc and .pyo files, and __pycache__ directories. It's also very fast.

Usage is simply:

$ cd /path/to/directory
$ pyclean

The auto keyword specifies that the type of the variable that is being declared will be automatically deducted from its initializer. In case of functions, if their return type is auto then that will be evaluated by return type expression at runtime.

It can be very useful when we have to use the iterator. For e.g. for below code we can simply use the "auto" instead of writing the whole iterator syntax .

int main() 
{ 

// Initialize set 
set<int> s; 

s.insert(1); 
s.insert(4); 
s.insert(2); 
s.insert(5); 
s.insert(3); 

// iterator pointing to 
// position where 2 is 
auto pos = s.find(3); 

// prints the set elements 
cout << "The set elements after 3 are: "; 
for (auto it = pos; it != s.end(); it++) 
    cout << *it << " "; 

return 0; 
}

This is how we can use "auto" keyword

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

To do this using numpy, ie, if you have an array, a, instead of list_a:

a = np.array([1, 2, 4, 6])
my_filter = np.array([True, False, True, False], dtype=bool)
a[my_filter]
> array([1, 4])

select CPaymentType, sum(CAmount)

group by CPaymentType
