This is how I implemented my URL builder. I have created one Service class to provide the params for the URL

public interface ParamsProvider {

    String queryProvider(List<BasicNameValuePair> params);

    String bodyProvider(List<BasicNameValuePair> params);
}

The Implementation of methods are below

@Component
public class ParamsProviderImp implements ParamsProvider {
    @Override
    public String queryProvider(List<BasicNameValuePair> params) {
        StringBuilder query = new StringBuilder();
        AtomicBoolean first = new AtomicBoolean(true);
        params.forEach(basicNameValuePair -> {
            if (first.get()) {
                query.append("?");
                query.append(basicNameValuePair.toString());
                first.set(false);
            } else {
                query.append("&");
                query.append(basicNameValuePair.toString());
            }
        });
        return query.toString();
    }

    @Override
    public String bodyProvider(List<BasicNameValuePair> params) {
        StringBuilder body = new StringBuilder();
        AtomicBoolean first = new AtomicBoolean(true);
        params.forEach(basicNameValuePair -> {
            if (first.get()) {
                body.append(basicNameValuePair.toString());
                first.set(false);
            } else {
                body.append("&");
                body.append(basicNameValuePair.toString());
            }
        });
        return body.toString();
    }
}

When we need the query params for our URL, I simply call the service and build it. Example for that is below.

Class Mock{
@Autowired
ParamsProvider paramsProvider;
 String url ="http://www.google.lk";
// For the query params price,type
 List<BasicNameValuePair> queryParameters = new ArrayList<>();
 queryParameters.add(new BasicNameValuePair("price", 100));
 queryParameters.add(new BasicNameValuePair("type", "L"));
url = url+paramsProvider.queryProvider(queryParameters);
// You can use it in similar way to send the body params using the bodyProvider

}

From my experience, 25% effort is spent on Analysis; 50% for Design, Development and Unit Test; remaining 25% for testing. Most projects will fit within a +/-10% variance of this rule of thumb depending on the nature of the project, knowledge of resources, quality of inputs & outputs, etc. One can add a project management overhead within these percentages or as an overhead on top within a 10-15% range.

thanks Paul Wardrip in my case I use required.

@RequestMapping(value={ "/calificacion-usuario/{idUsuario}/{annio}/{mes}", "/calificacion-usuario/{idUsuario}" }, method=RequestMethod.GET)
public List<Calificacion> getCalificacionByUsuario(@PathVariable String idUsuario
        , @PathVariable(required = false) Integer annio
        , @PathVariable(required = false) Integer mes) throws Exception {
    return repositoryCalificacion.findCalificacionByName(idUsuario, annio, mes);
}

Let's assume this is your class:

class Test
{
    private $baz = 1;

    public function foo() { ... }

    public function bar() 
    {
        printf("baz = %d\n", $this->baz);
    }

    public static function staticMethod() { echo "static method\n"; }
}

From within the foo() method, let's look at the different options:

$this->staticMethod();

So that calls staticMethod() as an instance method, right? It does not. This is because the method is declared as public static the interpreter will call it as a static method, so it will work as expected. It could be argued that doing so makes it less obvious from the code that a static method call is taking place.

$this::staticMethod();

Since PHP 5.3 you can use $var::method() to mean <class-of-$var>::; this is quite convenient, though the above use-case is still quite unconventional. So that brings us to the most common way of calling a static method:

self::staticMethod();

Now, before you start thinking that the :: is the static call operator, let me give you another example:

self::bar();

This will print baz = 1, which means that $this->bar() and self::bar() do exactly the same thing; that's because :: is just a scope resolution operator. It's there to make parent::, self:: and static:: work and give you access to static variables; how a method is called depends on its signature and how the caller was called.

To see all of this in action, see this 3v4l.org output.

In case you are using MultiBinding with your TextBox you need to use BindingOperations.GetMultiBindingExpression method instead of BindingOperations.GetBindingExpression.

// Get the correct binding expression based on type of binding
//(simple binding or multi binding.
BindingExpressionBase binding = 
  BindingOperations.GetBindingExpression(element, prop);
if (binding == null)
{
    binding = BindingOperations.GetMultiBindingExpression(element, prop);
}

if (binding != null)
{
     object value = element.GetValue(prop);
     if (string.IsNullOrEmpty(value.ToString()) == true)
     {
         binding.UpdateTarget();
     }
     else
     {
          binding.UpdateSource();
     }
}

var d = new Date();
var v = new Date();
v.setMinutes(d.getMinutes()+20);

If you are using create-react-app on C9 just run this command to start

npm run start --public $C9_HOSTNAME

And access the app from whatever your hostname is (eg type $C_HOSTNAME in the terminal to get the hostname)

You just need to return standard ContentResult and set ContentType to "application/json". You can create custom ActionResult for it:

public class JsonStringResult : ContentResult
{
    public JsonStringResult(string json)
    {
        Content = json;
        ContentType = "application/json";
    }
}

And then return it's instance:

[HttpPost]
public JsonResult UpdateBatchSearchMembers()
{
    string returntext;
    if (!System.IO.File.Exists(path))
        returntext = Properties.Settings.Default.EmptyBatchSearchUpdate;
    else
        returntext = Properties.Settings.Default.ResponsePath;

    return new JsonStringResult(returntext);
}

A HashMap can hold any object as a value, even if it is another HashMap. Eclipse is suggesting that you declare the types because that is the recommended practice for Collections. under Java 5. You are free to ignore Eclipse's suggestions.

Under Java 5, an int (or any primitive type) will be autoboxed into an Integer (or other corresponding type) when you add it to a collection. Be careful with this though, as there are some catches to using autoboxing.

If you use docker, remove all images. They used many space....

Stop all containers

docker stop $(docker ps -a -q)

Delete all containers

docker rm $(docker ps -a -q)

Delete all images

docker rmi $(docker images -q)

Works to me

This is a minor update, but since Java 7, proxy connections can now be created programmatically rather than through system properties. This may be useful if:

1. Proxy needs to be dynamically rotated during the program's runtime
2. Multiple parallel proxies need to be used
3. Or just make your code cleaner :)

Here's a contrived example in groovy:

// proxy configuration read from file resource under "proxyFileName"
String proxyFileName = "proxy.txt"
String proxyPort = "1234"
String url = "http://www.promised.land"
File testProxyFile = new File(proxyFileName)
URLConnection connection

if (!testProxyFile.exists()) {

    logger.debug "proxyFileName doesn't exist.  Bypassing connection via proxy."
    connection = url.toURL().openConnection()

} else {
    String proxyAddress = testProxyFile.text
    connection = url.toURL().openConnection(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyAddress, proxyPort)))
}

try {
    connection.connect()
}
catch (Exception e) {
    logger.error e.printStackTrace()
}

Full Reference: http://docs.oracle.com/javase/7/docs/technotes/guides/net/proxies.html

You can use C style string formatting:

"%d:%d:d" % (hours, minutes, seconds)

See here, especially: https://web.archive.org/web/20120415173443/http://diveintopython3.ep.io/strings.html

As for now there is no proper solution, as @spro says.

However, if you have an in-flight response and are using ReadableStream, you can close the stream to cancel the request.

fetch('http://example.com').then((res) => {
  const reader = res.body.getReader();

  /*
   * Your code for reading streams goes here
   */

  // To abort/cancel HTTP request...
  reader.cancel();
});

Unfortunately, this is not possible. Per the spec:

Generated content does not alter the document tree. In particular, it is not fed back to the document language processor (e.g., for reparsing).

In other words, for string values this means the value is always treated literally. It is never interpreted as markup, regardless of the document language in use.

As an example, using the given CSS with the following HTML:

<h1 class="header">Title</h1>

... will result in the following output:

<a href="#top">Back</a>Title

In this case you could use something like this:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

It should supply you with a query like:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

The Equals method does a reference comparison - if the arrays are different objects, this will indeed return false.

To check if the arrays contain identical values (and in the same order), you will need to iterate over them and test equality on each.

There is this plugin on github that load content into an element. Here is the repo

https://github.com/abdi0987/ViaJS

you can find if one has been initialized by comparing the references with the default instance:

GRPCContainer container = myGrpcResponseBean.getContainer();
if (container.getDefaultInstanceForType() != container) {
...
}

I'm in windows 10, using WAMP64 server. Searched for my.cnf and my.ini. Found my.ini in C:\wamp64\bin\mariadb\mariadb10.2.14.

Following the instructions from the colleagues:

1. Opened the quick start menu from Wampserver, selected 'Stop All Services'
2. Opened my.ini in a text editor, searched for [mysqld]
3. Added 'skip-grant-tables' at the end of the [mysqld] section (but within it)
4. Save the file, leave the editor open
5. In the Wampserver menu, select "Restart Services'. There will be a warning about the skip-grant-tables option
6. In the Wampserver menu select MySQL to open the prompt
7. It asked for a password, just press enter
8. Paste the command ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';
9. It must report that the operation was successful (no tables affected)
10. In the my.ini file, erase the 'skip-grant-tables' line, save the file
11. In the WampServer menu, select once more Restart Service

Now you can enter with the new password. Thanks to all answers here.

Based on the answer which is already in the question and on this article: https://handcraftsman.wordpress.com/2008/11/11/how-to-get-c-property-names-without-magic-strings/ I am presenting my solution to this problem:

public static class PropertyNameHelper
{
    /// <summary>
    /// A static method to get the Propertyname String of a Property
    /// It eliminates the need for "Magic Strings" and assures type safety when renaming properties.
    /// See: http://stackoverflow.com/questions/2820660/get-name-of-property-as-a-string
    /// </summary>
    /// <example>
    /// // Static Property
    /// string name = PropertyNameHelper.GetPropertyName(() => SomeClass.SomeProperty);
    /// // Instance Property
    /// string name = PropertyNameHelper.GetPropertyName(() => someObject.SomeProperty);
    /// </example>
    /// <typeparam name="T"></typeparam>
    /// <param name="propertyLambda"></param>
    /// <returns></returns>
    public static string GetPropertyName<T>(Expression<Func<T>> propertyLambda)
    {
        var me = propertyLambda.Body as MemberExpression;

        if (me == null)
        {
            throw new ArgumentException("You must pass a lambda of the form: '() => Class.Property' or '() => object.Property'");
        }

        return me.Member.Name;
    }
    /// <summary>
    /// Another way to get Instance Property names as strings.
    /// With this method you don't need to create a instance first.
    /// See the example.
    /// See: https://handcraftsman.wordpress.com/2008/11/11/how-to-get-c-property-names-without-magic-strings/
    /// </summary>
    /// <example>
    /// string name = PropertyNameHelper((Firma f) => f.Firmenumsatz_Waehrung);
    /// </example>
    /// <typeparam name="T"></typeparam>
    /// <typeparam name="TReturn"></typeparam>
    /// <param name="expression"></param>
    /// <returns></returns>
    public static string GetPropertyName<T, TReturn>(Expression<Func<T, TReturn>> expression)
    {
        MemberExpression body = (MemberExpression)expression.Body;
        return body.Member.Name;
    }
}

And a Test which also shows the usage for instance and static properties:

[TestClass]
public class PropertyNameHelperTest
{
    private class TestClass
    {
        public static string StaticString { get; set; }
        public string InstanceString { get; set; }
    }

    [TestMethod]
    public void TestGetPropertyName()
    {
        Assert.AreEqual("StaticString", PropertyNameHelper.GetPropertyName(() => TestClass.StaticString));

        Assert.AreEqual("InstanceString", PropertyNameHelper.GetPropertyName((TestClass t) => t.InstanceString));
    }
}

You can do it with using a FileOutputStream and the writeTo method.

ByteArrayOutputStream byteArrayOutputStream = getByteStreamMethod();
try(OutputStream outputStream = new FileOutputStream("thefilename")) {
    byteArrayOutputStream.writeTo(outputStream);
}

Source: "Creating a file from ByteArrayOutputStream in Java." on Code Inventions

Even after this my code is working fine , so i just removed all warning messages with this statement at line 1 .

<?php error_reporting(E_ERROR); ?>

There is a String.prototype.includes in ES6:

"potato".includes("to");
> true

Note that this does not work in Internet Explorer or some other old browsers with no or incomplete ES6 support. To make it work in old browsers, you may wish to use a transpiler like Babel, a shim library like es6-shim, or this polyfill from MDN:

if (!String.prototype.includes) {
  String.prototype.includes = function(search, start) {
    'use strict';
    if (typeof start !== 'number') {
      start = 0;
    }

    if (start + search.length > this.length) {
      return false;
    } else {
      return this.indexOf(search, start) !== -1;
    }
  };
}

A bare repository is pretty much something you only push to and fetch from. You cannot do much directly "in it": you cannot check stuff out, create references (branches, tags), run git status, etc.

If you want to create a new branch in a bare Git repository, you can push a branch from a clone to your bare repo:

# initialize your bare repo
$ git init --bare test-repo.git

# clone it and cd to the clone's root directory
$ git clone test-repo.git/ test-clone
Cloning into 'test-clone'...
warning: You appear to have cloned an empty repository.

I rectified the error 'ASP 0251 : 80004005' Response Buffer Limit as follow:

To increase the buffering limit in IIS 6, follow these steps:

Click Start, click Run, type cmd, and then click OK. Type the following command, and then press ENTER: cd /d %systemdrive%\inetpub\adminscripts Type the following command, and then press ENTER: cscript.exe adsutil.vbs SET w3svc/aspbufferinglimit LimitSize Note LimitSize represents the buffering limit size in bytes. For example, the number 67108864 sets the buffering limit size to 64 MB. To confirm that the buffer limit is set correctly, follow these steps:

Click Start, click Run, type cmd, and then click OK. Type the following command, and then press ENTER: cd /d %systemdrive%\inetpub\adminscripts Type the following command, and then press ENTER: cscript.exe adsutil.vbs GET w3svc/aspbufferinglimit

Inside your Stack, you should wrap your background widget in a Positioned.fill.

return new Stack(
  children: <Widget>[
    new Positioned.fill(
      child: background,
    ),
    foreground,
  ],
);

I figured out a simple solution to the PHP include stuff. Simply rename all your .html files to .php and your're good to go.

For the height of a div to be responsive, it must be inside a parent element with a defined height to derive it's relative height from.

If you set the height of the container holding the image and text box on the right, you can subsequently set the heights of its two children to be something like 75% and 25%.

However, this will get a bit tricky when the site layout gets narrower and things will get wonky. Try setting the padding on .contentBg to something like 5.5%.

My suggestion is to use Media Queries to tweak the padding at different screen sizes, then bump everything into a single column when appropriate.

With java 8:

Arrays.stream(MyEnum.values()).map(Enum::name)
                    .collect(Collectors.toList()).toArray();

You need to await the GetAsync method. It will then throw a TaskCanceledException if it has timed out. Additionally, GetStringAsync and GetStreamAsync internally handle timeout, so they will NEVER throw.

string baseAddress = "http://localhost:8080/";
var client = new HttpClient() 
{ 
    BaseAddress = new Uri(baseAddress), 
    Timeout = TimeSpan.FromMilliseconds(1) 
};
try
{
    var s = await client.GetAsync();
}
catch(Exception e)
{
    Console.WriteLine(e.Message);
    Console.WriteLine(e.InnerException.Message);
}

My version: use data attributes and Vanilla JavaScript

<div class="test-checkbox">
    Group One: <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Eat" />Eat</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Sleep" />Sleep</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupOne" value="Play" />Play</label>
    <br />
    Group Two: <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Fat" />Fat</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Comfort" />Comfort</label>
    <label>
        <input type="checkbox" data-limit="only-one-in-a-group" name="groupTwo" value="Happy" />Happy</label>
</div>
<script>
    let cbxes = document.querySelectorAll('input[type="checkbox"][data-limit="only-one-in-a-group"]');
    [...cbxes].forEach((cbx) => {
        cbx.addEventListener('change', (e) => {
            if (e.target.checked)
                uncheckOthers(e.target);
        });
    });
    function uncheckOthers (clicked) {
        let name = clicked.getAttribute('name');
        // find others in same group, uncheck them
        [...cbxes].forEach((other) => {
            if (other != clicked && other.getAttribute('name') == name)
                other.checked = false;
        });
    }

On my machine (Win10), the uninstaller was located at C:\ProgramData\Anaconda3\Uninstall-Anaconda3.exe.

You can pass array or dictionary. Here, I am taking NSMutableDictionary.

NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
[contentDictionary setValue:@"a" forKey:@"b"];
[contentDictionary setValue:@"c" forKey:@"d"];

To generate a JSON string from a NSDictionary or NSArray, You don't need to import any third party framework. Just use following code:-

NSError *error; 
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:contentDictionary // Here you can pass array or dictionary
                    options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string
                    error:&error];
NSString *jsonString;
if (jsonData) {
    jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    //This is your JSON String
    //NSUTF8StringEncoding encodes special characters using an escaping scheme
} else {
    NSLog(@"Got an error: %@", error);
    jsonString = @"";
}
NSLog(@"Your JSON String is %@", jsonString);

Something like this substitutions will be needed for your tables and field names.

Declare @TableUsers Table (User_ID, MyRowCount Int Identity(1,1)
Declare @i Int, @MaxI Int, @UserID nVarchar(50)

Insert into @TableUser
Select User_ID
From Users 
Where (My Criteria)
Select @MaxI = @@RowCount, @i = 1

While @i <= @MaxI
Begin
Select @UserID = UserID from @TableUsers Where MyRowCount = @i
Exec prMyStoredProc @UserID
Select

 @i = @i + 1, @UserID = null
End

To check if a string is empty or contains only whitespace you could use:

shopt -s extglob  # more powerful pattern matching

if [ -n "${str##+([[:space:]])}" ]; then
    echo '$str is not null or space'
fi

See Shell Parameter Expansion and Pattern Matching in the Bash Manual.

getchar() reads a single character of input and returns that character as the value of the function. If there is an error reading the character, or if the end of input is reached, getchar() returns a special value, represented by EOF.

Just another example to add BigDecimals. Key point is that they are immutable and they can be initialized only in the constructor. Here is the code:

import java.util.*;
import java.math.*;

public class Main {
    public static void main(String[] args) {
        Scanner sc;
        boolean first_right_number = false;
        BigDecimal initBigDecimal = BigDecimal.ZERO;
        BigDecimal add1 = BigDecimal.ZERO;
        BigDecimal add2 = BigDecimal.ZERO;

        while (!first_right_number)
        {
            System.out.print("Enter a first single numeric value: ");
            sc = new Scanner(System.in);
            if (sc.hasNextBigDecimal()) 
            {
                first_right_number = true;
                add1 = sc.nextBigDecimal();
            }
        }

        boolean second_right_number = false;
        while (!second_right_number)
        {
            System.out.print("Enter a second single numeric value: ");
            sc = new Scanner(System.in);
            if (sc.hasNextBigDecimal()) 
            {
                second_right_number = true;
                add2 = sc.nextBigDecimal();
            }
        }
        BigDecimal result = initBigDecimal.add(add1).add(add2);
        System.out.println("Sum of the 2 numbers is: " + result.toString());
    }
}

You don't need a function for it - simply use the bracket notation:

var side = columns['right'];

This is equal to dot notation, var side = columns.right;, except the fact that right could also come from a variable, function return value, etc., when using bracket notation.

If you NEED a function for it, here it is:

function read_prop(obj, prop) {
    return obj[prop];
}

To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:

var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};

you can access property x of c as follows:

var cx = foo['c']['x']

If a property is undefined, an attempt to reference it will return undefined (not null or false):

foo['c']['q'] === null
// returns false

foo['c']['q'] === false
// returns false

foo['c']['q'] === undefined
// returns true

just type the below command in terminal

ps -ef |grep 'catalina'

copy the value of process id then type the following command and paste process id

 kill -9 processid

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60

DateTime.Now.ToString("HH:mm:ss tt");

this gives it to you as a string.

There are several good answers here, so let me provide a terrible one:

: you can type in anything below, doesnt have to match anything

yum whatprovides "me with a life"

: result of the above (some liberties taken with spacing):

: the key result above is that "primary_db" files were downloaded

: filelists are downloaded EVEN IF you have keepcache=0 in your yum.conf

: note you can limit this to "primary_db.sqlite" if you really want

find /var/cache/yum -name '*.sqlite'

: if you download/install a new repo, run the exact same command again
: to get the databases for the new repo

: if you know sqlite you can stop reading here

: if not heres a sample command to dump the contents

echo 'SELECT packages.name, GROUP_CONCAT(files.name, ", ") AS files FROM files JOIN packages ON (files.pkgKey = packages.pkgKey) GROUP BY packages.name LIMIT 10;' | sqlite3 -line /var/cache/yum/x86_64/7/base/gen/primary_db.sqlite 

: remove "LIMIT 10" above for the whole list

: format chosen for proof-of-concept purposes, probably can be improved a lot

Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

Just to add to the great solutions. I used recursion to solve this.

            const flattenArray = () => {
                let result = [];
                return function flatten(arr) {
                    for (let i = 0; i < arr.length; i++) {
                        if (!Array.isArray(arr[i])) {
                            result.push(arr[i]);
                        } else {
                            flatten(arr[i])
                        }
                    }
                    return result;
                }
            }

This is my simple example, the key is the ContextThemeWrapper wrapper, without it, my style does not work, and using the three parameters constructor of the View.

ContextThemeWrapper themeContext = new ContextThemeWrapper(this, R.style.DefaultLabelStyle);
TextView tv = new TextView(themeContext, null, 0);
tv.setText("blah blah ...");
layout.addView(tv);

Using just jQuery, vanilla Javascript, and the table2CSV library:

export-to-html-table-as-csv-file-using-jquery

Put this code into a script to be loaded in the head section:

 $(document).ready(function () {
    $('table').each(function () {
        var $table = $(this);

        var $button = $("<button type='button'>");
        $button.text("Export to spreadsheet");
        $button.insertAfter($table);

        $button.click(function () {
            var csv = $table.table2CSV({
                delivery: 'value'
            });
            window.location.href = 'data:text/csv;charset=UTF-8,' 
            + encodeURIComponent(csv);
        });
    });
})

Notes:

Requires jQuery and table2CSV: Add script references to both libraries before the script above.

The table selector is used as an example, and can be adjusted to suit your needs.

It only works in browsers with full Data URI support: Firefox, Chrome and Opera, not in IE, which only supports Data URIs for embedding binary image data into a page.

For full browser compatibility you would have to use a slightly different approach that requires a server side script to echo the CSV.

I've read all of the above answers but it seems like they have no common strategy. I found a good article about best practices in Design API from Microsoft Documents. I think you should refer.

In more complex systems, it can be tempting to provide URIs that enable a client to navigate through several levels of relationships, such as /customers/1/orders/99/products. However, this level of complexity can be difficult to maintain and is inflexible if the relationships between resources change in the future. Instead, try to keep URIs relatively simple. Once an application has a reference to a resource, it should be possible to use this reference to find items related to that resource. The preceding query can be replaced with the URI /customers/1/orders to find all the orders for customer 1, and then /orders/99/products to find the products in this order.

.

Tip

Avoid requiring resource URIs more complex than collection/item/collection.

you can only pass one value, but it can be an array with multiples values within, as example:

function step1(){
  let server = "myserver.com";
  let data = "so much data, very impresive";
  return Promise.resolve([server, data]);
}

on the other side, you can use the destructuring expression for ES2015 to get the individual values.

function step2([server, data]){
  console.log(server); // print "myserver.com"
  console.log(data);   // print "so much data, very impresive"
  return Promise.resolve("done");
}

to call both promise, chaining them:

step1()
.then(step2)
.then((msg)=>{
  console.log(msg); // print "done"
})

I think that it's around 2GB. While the answer by Pete Kirkham is very interesting and probably holds truth, I have allocated upwards of 3GB without error, however it did not use 3GB in practice. That might explain why you were able to allocate 2.5 GB on 2GB RAM with no swap space. In practice, it wasn't using 2.5GB.

Use any method described in the previous post to somehow catch the mysql error.
Most common is:

$res = mysql_query('bla');
if ($res===false) {
  //error
  die();
}
//normal page

This would also work:

function error() {
  //error
  die()
}
$res = mysql_query('bla') or error();
//normal page

try { ... } catch {Exception $e) { .... } will not work!

Note: Not directly related to you question but I think it would much more better if you display something usefull to the user. I would never revisit a website that just displays a blank screen or any mysterious error message.

You can use the display property of style. Intialy set the result section style as

style = "display:none"

Then the div will not be visible and there won't be any white space.

Once the search results are being populated change the display property using the java script like

document.getElementById("someObj").style.display = "block"

Using java script you can make the div invisible

document.getElementById("someObj").style.display = "none"

SELECT * FROM Employees
WHERE rownum <= 3
ORDER BY Salary ;

A pure bash solution:

shopt -s nullglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} (non-hidden) directories"

If you also want to count the hidden directories:

shopt -s nullglob dotglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} directories (including hidden ones)"

Note that this will also count links to directories. If you don't want that, it's a bit more difficult with this method.

Using find:

find /path/to/directory -type d \! -name . -prune -exec printf x \; | wc -c

The trick is to output an x to stdout each time a directory is found, and then use wc to count the number of characters. This will count the number of all directories (including hidden ones), excluding links.

The methods presented here are all safe wrt to funny characters that can appear in file names (spaces, newlines, glob characters, etc.).

HTML:

First, we will need to add a class to your text container so that we can access and style it accordingly.

<div class="col-xs-5 textContainer">
     <h3 class="text-left">Link up with other gamers all over the world who share the same tastes in games.</h3>
</div>

CSS:

Next, we will apply the following styles to align it vertically, according to the size of the image div next to it.

.textContainer { 
    height: 345px; 
    line-height: 340px;
}

.textContainer h3 {
    vertical-align: middle;
    display: inline-block;
}

All Done! Adjust the line-height and height on the styles above if you believe that it is still slightly out of align.

WORKING EXAMPLE

Thanks for enlightening us Cypawer.

I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi

and it worked flawlessly.

Set the href attribute as href="javascript:;"

<ul class="product-info">
  <li>
   <a href="javascript:;">YOU CLICK THIS TO SHOW/HIDE</a>
  <div class="toggle">
    <p>CONTENT TO SHOW/HIDE</p>
  </div>
 </li>
</ul>

the solution: for type entity use option "data" but value is a object. ie:

$em = $this->getDoctrine()->getEntityManager();

->add('sucursal', 'entity', array
(

    'class' => 'TestGeneralBundle:Sucursal',
    'property'=>'descripcion',
    'label' => 'Sucursal',
    'required' => false,
    'data'=>$em->getReference("TestGeneralBundle:Sucursal",3)           

))

Seems like problem of the old smtplib. In python2.7 everything works fine.

Update: Yep, server.ehlo() also could help.

If the table is already created in the database, then you can add a unique constraint later on by using this SQL query:

ALTER TABLE dbo.User
  ADD CONSTRAINT ucCodes UNIQUE (fcode, scode, dcode)

alter table table_name add primary key (col_name1, col_name2);

Unfortunately SQL Developer doesn't fully honour the set echo off command that would (appear to) solve this in SQL*Plus.

The only workaround I've found for this is to save what you're doing as a script, e.g. test.sql with:

set echo off
spool c:\test.csv 
select /*csv*/ username, user_id, created from all_users;
spool off;

And then from SQL Developer, only have a call to that script:

@test.sql

And run that as a script (F5).

Saving as a script file shouldn't be much of a hardship anyway for anything other than an ad hoc query; and running that with @ instead of opening the script and running it directly is only a bit of a pain.

A bit of searching found the same solution on the SQL Developer forum, and the development team suggest it's intentional behaviour to mimic what SQL*Plus does; you need to run a script with @ there too in order to hide the query text.

My own version of Kim T's code above which combines with some jQuery and allows for targeting of specific iframes.

$(function() {
    callPlayer($('#iframe')[0], 'unMute');
});

function callPlayer(iframe, func, args) {
    if ( iframe.src.indexOf('youtube.com/embed') !== -1) {
        iframe.contentWindow.postMessage( JSON.stringify({
            'event': 'command',
            'func': func,
            'args': args || []
        } ), '*');
    }
}

There is a built-in function in bytearray that does what you intend.

bytearray.fromhex("de ad be ef 00")

It returns a bytearray and it reads hex strings with or without space separator.

if you're after the catalina.out log and you are using eclispe with tomcat, this works for me:

• create catelina.out some where in your computer. In my case, I put it in logs directory of my tomcat install directory e.g: /opt/apache-tomcat-7.0.83/logs/catena.out
• go to your eclipse, in the servers tab, double-click on the Tomcat Server. You will get a screen called Overview.
• Click on "Open launch configuration". Then click on the "Common" tab.
• At standard input and output section, check "output file", click on file system and then selected the folder where your create your catelina.out.
• Finally, restart the Tomcat server.

I would join @Nicholas in recommending PyInstaller (with the --onefile flag), but be warned: do not use the "latest release", PyInstaller 1.3 -- it's years old. Use the "pre-release" 1.4, download it here -- or even better the code from the svn repo -- install SVN and run svn co http://svn.pyinstaller.org/trunk pyinstaller.

As @Nicholas implies, dynamic libraries cannot be run from the same file as the rest of the executable -- but fortunately they can be packed together with all the rest in a "self-unpacking" executable that will unpack itself into some temporary directory as needed; PyInstaller does a good job at this (and at many other things -- py2exe is more popular, but pyinstaller in my opinion is preferable in all other respects).

Inside a module

Option Explicit
dim objExcelApp as Excel.Application
dim wb as Excel.Workbook

sub Initialize()
   set objExcelApp = new Excel.Application
end sub

sub ProcessDataWorkbook()
    dim ws as Worksheet
    set wb = objExcelApp.Workbooks.Open("path to my workbook")
    set ws = wb.Sheets(1)

    ws.Cells(1,1).Value = "Hello"
    ws.Cells(1,2).Value = "World"

    'Close the workbook
    wb.Close
    set wb = Nothing
end sub

sub Release()
   set objExcelApp = Nothing
end sub

Pay attention that in http.Request header "Host" can not be set via Set method

req.Header.Set("Host", "domain.tld")

but can be set directly:

req.Host = "domain.tld":

req, err := http.NewRequest("GET", "http://10.0.0.1/", nil)
if err != nil {
    ...
}

req.Host = "domain.tld"
client := &http.Client{}
resp, err := client.Do(req)

A slightly clumsier but faster approach for larger datasets involves getting the counts for a column of interest, sorting the counts highest to lowest, and then de-duplicating on a subset to only retain the largest cases. The code example is following:

>>> import pandas as pd
>>> source = pd.DataFrame(
        {
            'Country': ['USA', 'USA', 'Russia', 'USA'], 
            'City': ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
            'Short name': ['NY', 'New', 'Spb', 'NY']
        }
    )
>>> grouped_df = source\
        .groupby(['Country','City','Short name'])[['Short name']]\
        .count()\
        .rename(columns={'Short name':'count'})\
        .reset_index()\
        .sort_values('count', ascending=False)\
        .drop_duplicates(subset=['Country', 'City'])\
        .drop('count', axis=1)
>>> print(grouped_df)
  Country              City Short name
1     USA          New-York         NY
0  Russia  Sankt-Petersburg        Spb

Using Eclipse Collections

int count = Strings.asChars("a.b.c.d").count(c -> c == '.');

If you have more than one character to count, you can use a CharBag as follows:

CharBag bag = Strings.asChars("a.b.c.d").toBag();
int count = bag.occurrencesOf('.');

Note: I am a committer for Eclipse Collections.

When you execute a method (i.e. function assigned to an object), inside it you can use this variable to refer to this object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
obj.someMethod(); // logs true

If you assign a method from one object to another, its this variable refers to the new object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
  someProperty: false,_x000D_
  someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false

The same thing happens when you assign requestAnimationFrame method of window to another object. Native functions, such as this, has build-in protection from executing it in other context.

There is a Function.prototype.call() function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({}) gives TypeError: Illegal invocation. However, alert.call(window) works fine, because now alert is executed in its original scope.

If you use .call() with your object like that:

support.animationFrame.call(window, function() {});

it works fine, because requestAnimationFrame is executed in scope of window instead of your object.

However, using .call() every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind(). It has similar effect to .call(), but instead of calling the function, it creates a new function which will always be called in specified context. For example:

window.someProperty = true;_x000D_
var obj = {_x000D_
  someProperty: false,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true

The only downside of Function.prototype.bind() is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.

As you probably already figured out, you can use .bind() to always execute requestAnimationFrame in context of window. Your code could look like this:

var support = {
    animationFrame: (window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame).bind(window)
};

Then you can simply use support.animationFrame(function() {});.

This seems like the easiest (but not most robust) way to me. Simply compute the sum from row 6 to the maximum allowed row number, as specified by Excel. According to this site, the maximum is currently 1048576, so the following should work for you:

=sum(c6:c1048576)

For more robust solutions, see the other answers.

Just comment out "Defaults env_reset" in /etc/sudoers

I had this problem and then found these pages: Here you can see that apache library is deprecated, but it's not removed, so it should work. It doesn't.

See.

And here you can see how to include apache library to your project

I resolved problem by adding following to my build.gradle file as recommended in second link.

android {
    useLibrary 'org.apache.http.legacy'
}

However this only works if you are using gradle 1.3.0-beta2 or greater, so you will have to add this to buildscript dependencies if you are on a lower version:

classpath 'com.android.tools.build:gradle:1.3.0-beta2'

Hope this helps.

Similarly I did for long:

myLongVariable = (!string.IsNullOrEmpty(cbLong.SelectedItem.Value)) ? Convert.ToInt64(cbLong.SelectedItem.Value) : (long?)null;

You can use this func:

func randomString(length int) string {
    b := make([]byte, length)
    rand.Read(b)
    return fmt.Sprintf("%x", b)[:length]
}

If you're using Rails, String#camelize is what you're looking for.

  "active_record".camelize                # => "ActiveRecord"
  "active_record".camelize(:lower)        # => "activeRecord"

If you want to get an actual class, you should use String#constantize on top of that.

"app_user".camelize.constantize

Remark: not too easy way, but workable and it has its own unique pros.

If one want to clone only HEAD revision of a repository and only HEADs of all the its submodules (i.e. to checkout "trunk"), then one can use following Lua script. Sometimes simple command git submodule update --init --recursive --remote --no-fetch --depth=1 can result in an unrecoverable git error. In this case one need to clean up subdirectory of .git/modules directory and clone submodule manually using git clone --separate-git-dir command. The only complexity is to find out URL, path of .git directory of submodule and path of submodule in superproject tree.

Remark: the script is only tested against https://github.com/boostorg/boost.git repository. Its peculiarities: all the submodules hosted on the same host and .gitmodules contains only relative URLs.

-- mkdir boost ; cd boost ; lua ../git-submodules-clone-HEAD.lua https://github.com/boostorg/boost.git .
local module_url = arg[1] or 'https://github.com/boostorg/boost.git'
local module = arg[2] or module_url:match('.+/([_%d%a]+)%.git')
local branch = arg[3] or 'master'
function execute(command)
    print('# ' .. command)
    return os.execute(command)
end
-- execute('rm -rf ' .. module)
if not execute('git clone --single-branch --branch master --depth=1 ' .. module_url .. ' ' .. module) then
    io.stderr:write('can\'t clone repository from ' .. module_url .. ' to ' .. module .. '\n')
    return 1
end
-- cd $module ; git submodule update --init --recursive --remote --no-fetch --depth=1
execute('mkdir -p ' .. module .. '/.git/modules')
assert(io.input(module .. '/.gitmodules'))
local lines = {}
for line in io.lines() do
    table.insert(lines, line)
end
local submodule
local path
local submodule_url
for _, line in ipairs(lines) do
    local submodule_ = line:match('^%[submodule %"([_%d%a]-)%"%]$')
    if submodule_ then
        submodule = submodule_
        path = nil
        submodule_url = nil
    else
        local path_ = line:match('^%s*path = (.+)$')
        if path_ then
            path = path_
        else
            submodule_url = line:match('^%s*url = (.+)$')
        end
        if submodule and path and submodule_url then
            -- execute('rm -rf ' .. path)
            local git_dir = module .. '/.git/modules/' .. path:match('^.-/(.+)$')
            -- execute('rm -rf ' .. git_dir)
            execute('mkdir -p $(dirname "' .. git_dir .. '")')
            if not execute('git clone --depth=1 --single-branch --branch=' .. branch .. ' --separate-git-dir ' .. git_dir .. ' ' .. module_url .. '/' .. submodule_url .. ' ' .. module .. '/' .. path) then
                io.stderr:write('can\'t clone submodule ' .. submodule .. '\n')
                return 1
            end
            path = nil
            submodule_url = nil
        end

INTERSECT needs to be emulated in MySQL:

SELECT  'robot' AS `set`, r.*
FROM    robot r
WHERE   ROW(r.col1, r.col2, …) NOT IN
        (
        SELECT  col1, col2, ...
        FROM    tbd_robot
        )
UNION ALL
SELECT  'tbd_robot' AS `set`, t.*
FROM    tbd_robot t
WHERE   ROW(t.col1, t.col2, …) NOT IN
        (
        SELECT  col1, col2, ...
        FROM    robot
        )

If you want to copy the DataTable to another DataTable of different Schema Structure then you can do this:

• Firstly Clone the first DataType so that you can only get the structure.
• Then alter the newly created structure as per your need and then copy the data to newly created DataTable .

So:

Dim dt1 As New DataTable
dt1 = dtExcelData.Clone()
dt1.Columns(17).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(26).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(30).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(35).DataType = System.Type.GetType("System.Decimal")
dt1.Columns(38).DataType = System.Type.GetType("System.Decimal")
dt1 = dtprevious.Copy()

Hence you get the same DataTable but revised structure

Building upon Fabien Kruba's already excellent answer, I thought it would be nice if the ** portion of the URL could be given as a parameter to the controller method via an annotation, in a way which was similar to @RequestParam and @PathVariable, rather than always using a utility method which explicitly required the HttpServletRequest. So here's an example of how that might be implemented. Hopefully someone finds it useful.

Create the annotation, along with the argument resolver:

@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface WildcardParam {

    class Resolver implements HandlerMethodArgumentResolver {

        @Override
        public boolean supportsParameter(MethodParameter methodParameter) {
            return methodParameter.getParameterAnnotation(WildcardParam.class) != null;
        }

        @Override
        public Object resolveArgument(MethodParameter methodParameter, ModelAndViewContainer modelAndViewContainer, NativeWebRequest nativeWebRequest, WebDataBinderFactory webDataBinderFactory) throws Exception {
            HttpServletRequest request = nativeWebRequest.getNativeRequest(HttpServletRequest.class);
            return request == null ? null : new AntPathMatcher().extractPathWithinPattern(
                    (String) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE),
                    (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE));
        }

    }

}

Register the method argument resolver:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> resolvers) {
        resolvers.add(new WildcardParam.Resolver());
    }

}

Use the annotation in your controller handler methods to have easy access to the ** portion of the URL:

@RestController
public class SomeController {

    @GetMapping("/**")
    public void someHandlerMethod(@WildcardParam String wildcardParam) {
        // use wildcardParam here...
    }

}

I like the explanation From EdX (Microsoft: DEV210x Introduction to C++) for a similar problem:

"The enum represents the literal values of days as integers. Referring to the numeric types table, you see that an int takes 4 bytes of memory. 7 days x 4 bytes each would require 28 bytes of memory if the entire enum were stored but the compiler only uses a single element of the enum, therefore the size in memory is actually 4 bytes."

Try adding the drive letter:

include_path='.;c:\xampplite\php\pear\PEAR'

also verify that PEAR.php is actually there, it might be in \php\ instead:

include_path='.;c:\xampplite\php'

On older notebooks with integrated video Swing app starts and works much faster than JavaFX app. As for development, I'd recommend switch to Scala - comparable Scala Swing app contains 2..3 times less code than Java. As for Swing vs SWT: Netbeans GUI considerably faster than Eclipse...

In Oracle PL/SQL, if you are running a query that may return multiple rows, you need a cursor to iterate over the results. The simplest way is with a for loop, e.g.:

declare
  myname varchar2(20) := 'tom';
begin
  for result_cursor in (select * from mytable where first_name = myname) loop
    dbms_output.put_line(result_cursor.first_name);
    dbms_output.put_line(result_cursor.other_field);
  end loop;
end;

If you have a query that returns exactly one row, then you can use the select...into... syntax, e.g.:

declare 
  myname varchar2(20);
begin
  select first_name into myname 
    from mytable 
    where person_id = 123;
end;

I need more information really but it will be along the lines of..

SELECT table1.*, table2.col1, table2.col3 FROM table1 JOIN table2 USING(id)

Use rgba!

.alpha60 {
    /* Fallback for web browsers that don't support RGBa */
    background-color: rgb(0, 0, 0);
    /* RGBa with 0.6 opacity */
    background-color: rgba(0, 0, 0, 0.6);
    /* For IE 5.5 - 7*/
    filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000);
    /* For IE 8*/
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)";
}

In addition to this, you have to declare background: transparent for IE web browsers, preferably served via conditional comments or similar!

You install as assemblies by using:

• A setup program, that you author for your application.
• Using the gacutil.exe tool with the -i option from the command line.
• Dropping the assembly in %windir%\Assembly (only up to .NET 3.5, CLR 2.0)

You view the content of the GAC using:

• The gacutil.exe tool with the -l option.
• For .NET 2.0, 3.0 and 3.5 (CLR 2.0) browsing to %windir%\assembly using the Windows Explorer.

Note that the (physical) GAC location has changed for .NET 4.0. It is no longer in %windir%\Assembly, but now in %windir%\Microsoft.NET\assembly. However, you should never write any code that depends on the physical location anyway, because given the tools available that is hardly necessary (some "cool" homegrown system diagnostics tools aside).

(Edit: Forget my previous babble...)

Ok, there might be situations where you would go either to the model or to some other url... But I don't really think this belongs in the model, the view (or maybe the model) sounds more apropriate.

About the routes, as far as I know the routes is for the actions in controllers (wich usually "magically" uses a view), not directly to views. The controller should handle all requests, the view should present the results and the model should handle the data and serve it to the view or controller. I've heard a lot of people here talking about routes to models (to the point I'm allmost starting to beleave it), but as I understand it: routes goes to controllers. Of course a lot of controllers are controllers for one model and is often called <modelname>sController (e.g. "UsersController" is the controller of the model "User").

If you find yourself writing nasty amounts of logic in a view, try to move the logic somewhere more appropriate; request and internal communication logic probably belongs in the controller, data related logic may be placed in the model (but not display logic, which includes link tags etc.) and logic that is purely display related would be placed in a helper.

Here is an easy way to do it.

// echo get_header('X-Requested-With');
function get_header($field) {
    $headers = headers_list();
    foreach ($headers as $header) {
        list($key, $value) = preg_split('/:\s*/', $header);
        if ($key == $field)
            return $value;
    }
}

If you have YAML that conforms to the YAML 1.2 specification (released 2009) then you should use ruamel.yaml (disclaimer: I am the author of that package). It is essentially a superset of PyYAML, which supports most of YAML 1.1 (from 2005).

If you want to be able to preserve your comments when round-tripping, you certainly should use ruamel.yaml.

Upgrading @Jon's example is easy:

import ruamel.yaml as yaml

with open("example.yaml") as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

Use safe_load() unless you really have full control over the input, need it (seldom the case) and know what you are doing.

If you are using pathlib Path for manipulating files, you are better of using the new API ruamel.yaml provides:

from ruamel.yaml import YAML
from pathlib import Path

path = Path('example.yaml')
yaml = YAML(typ='safe')
data = yaml.load(path)

$('#submit').click(function(){
   if($('#myMessage').val() == ''){
      alert('Input can not be left blank');
   }
});

Update

If you don't want whitespace also u can remove them using jQuery.trim()

Description: Remove the whitespace from the beginning and end of a string.

$('#submit').click(function(){
   if($.trim($('#myMessage').val()) == ''){
      alert('Input can not be left blank');
   }
});

Very simple use of any

df <- <your structure>

df$Den <- apply(df,1,function(i) {ifelse(any(is.na(i)) | any(i != 1), 0, 1)})

Use Apache HttpComponents and wire it up with some collection code to access params by value: http://www.joelgerard.com/2012/09/14/parsing-query-strings-in-java-and-accessing-values-by-key/

You could also enforce a class to be static using metaclass.

class StaticClassError(Exception):
    pass


class StaticClass:
    __metaclass__ = abc.ABCMeta

    def __new__(cls, *args, **kw):
        raise StaticClassError("%s is a static class and cannot be initiated."
                                % cls)

class MyClass(StaticClass):
    a = 1
    b = 3

    @staticmethod
    def add(x, y):
        return x+y

Then whenever by accident you try to initialize MyClass you'll get an StaticClassError.

Currently, only MOBILE and WIFI is supported. Take a look and human readable type function.

Same issue occurred to me,But what I did was,

Just Replaced:

python manage.py runserver

with

python3 manage.py runserver

in the terminal(macOsX). Because I am using Python version 3.x

I haven't done any benchmarks, but this recipe "works for me".

The short version: use '%x' % val, then unhexlify the result. The devil is in the details, though, as unhexlify requires an even number of hex digits, which %x doesn't guarantee. See the docstring, and the liberal inline comments for details.

I was using XSSFWorkbook to read .xls, which resulted in InvalidFormatException. I have to use a more generic Workbook and Sheet to make it work.

This post helped me solved my problem.

I am using this script after I rename my iOS Project. It helps to change the directories name and make the names in sync.

http://github.com/ytbryan/rename

NOTE: you will need to manually change the scheme's name.

 select index_name, column_name
 from user_ind_columns
 where table_name = 'NAME';

OR use this:

select TABLE_NAME, OWNER 
from SYS.ALL_TABLES 
order by OWNER, TABLE_NAME 

And for Indexes:

select INDEX_NAME, TABLE_NAME, TABLE_OWNER 
from SYS.ALL_INDEXES 
order by TABLE_OWNER, TABLE_NAME, INDEX_NAME

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

add "tel:" along with your number to be dialed in your intent and then start your activity.

Intent myIntent = new Intent(Intent.ACTION_CALL);
 String phNum = "tel:" + "1234567890";
 myIntent.setData(Uri.parse(phNum));
  startActivity( myIntent ) ;

 select persons.personsid,name,info.id,address
    -> from persons
    -> inner join persons on info.infoid = info.info.id;

In javascript:

document.getElementById("myDIV").style.display = "none";

and in jquery:

$("#myDIV").css({display: "none"});
$("#myDIV").css({display: "block"});

and you can use:

$('#myDIV').hide();
$('#myDIV').show();

If you want to search inside the text, rather than view it, this works:

with unzipped_text as (
  select
    my_id
    ,utl_compress.lz_uncompress(my_compressed_blob) as my_blob
  from my_table
  where my_id='MY_ID'
)
select * from unzipped_text
where dbms_lob.instr(my_blob, utl_raw.cast_to_raw('MY_SEARCH_STRING'))>0;

If you use IOUtils from apache "commons-io" it's even easier:

InputStream is = getResources().openRawResource(R.raw.yourNewTextFile);
String s = IOUtils.toString(is);
IOUtils.closeQuietly(is); // don't forget to close your streams

when you have one certificate and 2 different web servers here how I fixed it:

1. List item
2. You should generate certificate at one of the servers as usually in IIS Then at that server you can also complete the certificate in IIS.
3. Run the program DigiCertUtil and export that working certificate
4. Go to the other web server in IIS in security certificates Import that file from step 3.
5. Then use that certificate to create the Binding.

Always try to log in using those credentials with SQL Management Studio. This might reveal some more details that you don't get at runtime in your code. I had checked the SQL + Windows authentication, restarted the server but still no luck. After trying to log in using SQL Management, I got this prompt:

Somehow the password had expired although the login was created just minutes before. Anyway, new password set, connection string updated and all's fine.

You need to look to see how the import statements are written in the related code. If examples/example_one.py uses the following import statement:

import api.api

...then it expects the root directory of the project to be in the system path.

The easiest way to support this without any hacks (as you put it) would be to run the examples from the top level directory, like this:

PYTHONPATH=$PYTHONPATH:. python examples/example_one.py 

strstr(request, "favicon") != NULL

The other answers didn't work for me, this is what ended up doing the trick for apache2:

1) Enable the headers mod:

sudo a2enmod headers

2) Create the /etc/apache2/mods-enabled/headers.conf file and insert:

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

3) Restart your server:

sudo service apache2 restart

Use the :checked selector to determine the checkbox's state:

$('input[type=checkbox]').click(function() {
    if($(this).is(':checked')) {
        ...
    } else {
        ...
    }
});

In C, you don't really have strings, as a generic first-class object. You have to manage them as arrays of characters, which mean that you have to determine how you would like to manage your arrays. One way is to normal variables, e.g. placed on the stack. Another way is to allocate them dynamically using malloc.

Once you have that sorted, you can copy the content of one array to another, to concatenate two strings using strcpy or strcat.

Having said that, C do have the concept of "string literals", which are strings known at compile time. When used, they will be a character array placed in read-only memory. It is, however, possible to concatenate two string literals by writing them next to each other, as in "foo" "bar", which will create the string literal "foobar".

As others have observed, you must either create a nullable column or provide a DEFAULT value. If that isn't flexible enough (e.g. if you need the new value to be computed for each row individually somehow), you can use the fact that in PostgreSQL, all DDL commands can be executed inside a transaction:

BEGIN;
ALTER TABLE mytable ADD COLUMN mycolumn character varying(50);
UPDATE mytable SET mycolumn = timeofday();    -- Just a silly example
ALTER TABLE mytable ALTER COLUMN mycolumn SET NOT NULL;
COMMIT;

You can use this function if it's multiple string df[!grepl("REVERSE|GENJJS", df$Name),]

You call tarfile.open with mode='w:gz', meaning "Open for gzip compressed writing."

You'll probably want to end the filename (the name argument to open) with .tar.gz, but that doesn't affect compression abilities.

BTW, you usually get better compression with a mode of 'w:bz2', just like tar can usually compress even better with bzip2 than it can compress with gzip.

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

warning! this does not work with links.

Simple, website view via intent,

Intent viewIntent = new Intent("android.intent.action.VIEW", Uri.parse("http://www.yoursite.in"));
startActivity(viewIntent);

Add internet permission in manifest file,

<uses-permission android:name="android.permission.INTERNET" /> 

In the manual for GNU make, they talk about this specific example when describing the value function:

The value function provides a way for you to use the value of a variable without having it expanded. Please note that this does not undo expansions which have already occurred; for example if you create a simply expanded variable its value is expanded during the definition; in that case the value function will return the same result as using the variable directly.

The syntax of the value function is:

 $(value variable)

Note that variable is the name of a variable; not a reference to that variable. Therefore you would not normally use a ‘$’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)

The result of this function is a string containing the value of variable, without any expansion occurring. For example, in this makefile:

 FOO = $PATH

 all:
         @echo $(FOO)
         @echo $(value FOO)

The first output line would be ATH, since the “$P” would be expanded as a make variable, while the second output line would be the current value of your $PATH environment variable, since the value function avoided the expansion.

This post maybe outdated but i found out the main cause why it usually hang is due to stack overflow for the redirectStandardoutput or if you have redirectStandarderror.

As the output data or the error data is large, it will cause a hang time as it is still processing for indefinite duration.

so to resolve this issue:

p.StartInfo.RedirectStandardoutput = False
p.StartInfo.RedirectStandarderror = False

That's because req and res are two different objects.

You need to look for the property on the same object you added it to.

value = value.setScale(2, RoundingMode.CEILING)

Try

$(this).attr("checked" , false );

A query string carries textual data so there is no option but to explode the array, encode it correctly and pass it in a representational format of your choice:

p1=value1&pN=valueN...
data=[value1,...,valueN]
data={p1:value1,...,pN:valueN}

and then decode it in your server side code.

Isn't using $scope.$watch to reflect the changes of scope variable better?

sudo apt-get update
sudo apt-get  install openjdk-8-jdk

this should work

On SQL Server? and on the same database server? Use three part naming.

INSERT INTO bar..tblFoobar( *fieldlist* )
SELECT *fieldlist* FROM foo..tblFoobar

This just moves the data. If you want to move the table definition (and other attributes such as permissions and indexes), you'll have to do something else.

Even though you have the methods compareTo(), if you want to make use of utilities like Collections.sort(), then you should also implement Comparable.

public class Fraction extends Number implements Comparable<Fraction> {
 ...
}

Also, for pretty display I recommend overriding toString()

public String toString() {
    return this.getNumerator() + "/" + this.getDenominator();
}

And finally, I'd make the class public so that you can use it from different packages.

When you install Python or Python3 using MacOS installer (downloaded from Python website) - it adds an exporter to your ~/.profile script. All you need to do is just source it. Restarting all the terminals should also do the trick.

WARNING - I believe it's better to just use pip3 with Python3 - for future benefits.

If you already have Python3 installed, the following steps work for me on macOS Mojave:

1. Install ansible first using sudo - sudo -H pip3 install ansible

2. you create a symlink to the Python's bin path

sudo ln -s /Library/Frameworks/Python.framework/Versions/Current/bin /Library/Frameworks/Python.framework/current_python_bin

and staple it to .profile

export PATH=$PATH:/Library/Frameworks/Python.framework/current_python_bin

3. run source ~/.profile and restart all terminal shells.

4. Type ansible --version

It is a permission issue.

try with sudo

Let's say you're building some chairs.

The diagram that shows how to build a chair and put it together corresponds to a software class.

Let's say you build five chairs according to the pattern in that diagram. Likewise, you could construct five software objects according to the pattern in a class.

Each chair has a unique number burned into the bottom of the seat to identify each specific chair. Chair 3 is one instance of a chair pattern. Likewise, memory location 3 can contain one instance of a software pattern.

So, an instance (chair 3) is a single unique, specific manifestation of a chair pattern.

tar.exe -acf out.zip in.txt

out.zip is an output folder or filename and in.txt is an input folder or filename. To use this command you should be in the file existing folder.

xcopy "$(ProjectDir)Views\Home\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\Home"

and if you want to copy entire folders:

xcopy /E /Y "$(ProjectDir)Views" "$(SolutionDir)MEFMVCPOC\Views"

Update: here's the working version

xcopy "$(ProjectDir)Views\ModuleAHome\Index.cshtml" "$(SolutionDir)MEFMVCPOC\Views\ModuleAHome\" /Y /I

Here are some commonly used switches with xcopy:

• /I - treat as a directory if copying multiple files.
• /Q - Do not display the files being copied.
• /S - Copy subdirectories unless empty.
• /E - Copy empty subdirectories.
• /Y - Do not prompt for overwrite of existing files.
• /R - Overwrite read-only files.

Image.paste does not work as expected when the background image also contains transparency. You need to use real Alpha Compositing.

Pillow 2.0 contains an alpha_composite function that does this.

background = Image.open("test1.png")
foreground = Image.open("test2.png")

Image.alpha_composite(background, foreground).save("test3.png")

EDIT: Both images need to be of the type RGBA. So you need to call convert('RGBA') if they are paletted, etc.. If the background does not have an alpha channel, then you can use the regular paste method (which should be faster).

You could use this one line change: Arrays.asList(set.toArray(new Object[set.size()]))

Map<String, List> mainMap = new HashMap<String, List>();

for(int i=0; i<something.size(); i++){
  Set set = getSet(...); 
  mainMap.put(differentKeyName, Arrays.asList(set.toArray(new Object[set.size()])));
}  

I just found another solution. I believe it's more a hack than a solution but it works on android 2.3.7 and android 4.3 (I've even tested that good old D-pad)

init your webview as usual and add this: (thanks Michael Bierman)

listView.setItemsCanFocus(true);

During the getView call:

editText.setOnFocusChangeListener(
    new OnFocusChangeListener(View view,boolean hasFocus){
        view.post(new Runnable() {
            @Override
            public void run() {
                view.requestFocus();
                view.requestFocusFromTouch();
            }
     });

For Swift 3

   DispatchQueue.main.async {
        // Write your code here
    }

You can use the sequence method list.extend to extend the list by multiple values from any kind of iterable, being it another list or any other thing that provides a sequence of values.

>>> lst = [1, 2]
>>> lst.append(3)
>>> lst.append(4)
>>> lst
[1, 2, 3, 4]

>>> lst.extend([5, 6, 7])
>>> lst.extend((8, 9, 10))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

>>> lst.extend(range(11, 14))
>>> lst
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

So you can use list.append() to append a single value, and list.extend() to append multiple values.

Easiest way I know of is to use "child_process" package which comes packaged with node.

Then you can do something like:

const spawn = require("child_process").spawn;
const pythonProcess = spawn('python',["path/to/script.py", arg1, arg2, ...]);

Then all you have to do is make sure that you import sys in your python script, and then you can access arg1 using sys.argv[1], arg2 using sys.argv[2], and so on.

To send data back to node just do the following in the python script:

print(dataToSendBack)
sys.stdout.flush()

And then node can listen for data using:

pythonProcess.stdout.on('data', (data) => {
    // Do something with the data returned from python script
});

Since this allows multiple arguments to be passed to a script using spawn, you can restructure a python script so that one of the arguments decides which function to call, and the other argument gets passed to that function, etc.

Hope this was clear. Let me know if something needs clarification.

If you have a table with an IDENTITY column that you want to reset the next value for you can use the following command:

ALTER TABLE <table name> 
    ALTER COLUMN <column name> 
        RESTART WITH <new value to restart with>;

Laravel 5.6 method: https://laravel.com/docs/5.6/views#passing-data-to-views

Example, with sharing a model collection to all views (AppServiceProvider.php):

use Illuminate\Support\Facades\View;
use App\Product;

public function boot()
{
    $products = Product::all();
    View::share('products', $products);

}

Similar answer, but I just wanted to make it available for an easy/quick test.

var input = $("<input>")_x000D_
               .attr("name", "mydata").val("go Rafa!");_x000D_
_x000D_
$('#easy_test').append(input);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
_x000D_
<form id="easy_test">_x000D_
  _x000D_
</form>

You need to encapsulate it into another object[] array, like this:

Foo(new Object[] { new object[]{ (object)"1", (object)"2" }});

If you want to check the python version in a particular cond environment you can also use conda list python

After looking at this and trying it out I found it actually didn't allow more than one instance of jquery to run at a time. After searching around I found that this did just the trick and was a whole lot less code.

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
    <script>var $j = jQuery.noConflict(true);</script>
    <script>
      $(document).ready(function(){
       console.log($().jquery); // This prints v1.4.2
       console.log($j().jquery); // This prints v1.9.1
      });
   </script>

So then adding the "j" after the "$" was all I needed to do.

$j(function () {
        $j('.button-pro').on('click', function () {
            var el = $('#cnt' + this.id.replace('btn', ''));
            $j('#contentnew > div').not(el).animate({
                height: "toggle",
                opacity: "toggle"
            }, 100).hide();
            el.toggle();
        });
    });

You don't need the AND keyword. Here's the correct syntax of the UPDATE statement:

UPDATE 
    shop_category 
SET 
    name = 'Secolul XVI - XVIII', 
    name_eng = '16th to 18th centuries' 
WHERE 
    category_id = 4768

If you're not set on rolling your own solution, check out this jQuery plugin:

malsup.com/jquery/form/

It will do that and more for you. It's highly recommended.

You need to add else in your lambda function. Because you are telling what to do in case your condition(here x < 90) is met, but you are not telling what to do in case the condition is not met.

sample['PR'] = sample['PR'].apply(lambda x: 'NaN' if x < 90 else x) 

Call MyMacro()

ActiveCell.Offset(1, 0).Activate

Do Until Selection.EntireRow.Hidden = False
If Selection.EntireRow.Hidden = True Then
ActiveCell.Offset(1, 0).Activate
End If
Loop

Check if ceil function and floor function returns the same value

static boolean isInteger(int n) 
{ 
return (int)(Math.ceil(n)) == (int)(Math.floor(n)); 
} 

Create a comparator which accepts the compare mode in its constructor and pass different modes for different scenarios based on your requirement

public class RecipeComparator implements Comparator<Recipe> {

public static final int COMPARE_BY_ID = 0;
public static final int COMPARE_BY_NAME = 1;

private int compare_mode = COMPARE_BY_NAME;

public RecipeComparator() {
}

public RecipeComparator(int compare_mode) {
    this.compare_mode = compare_mode;
}

@Override
public int compare(Recipe o1, Recipe o2) {
    switch (compare_mode) {
    case COMPARE_BY_ID:
        return o1.getId().compareTo(o2.getId());
    default:
        return o1.getInputRecipeName().compareTo(o2.getInputRecipeName());
    }
}

}

Actually for numbers you need to handle them separately check below

public static void main(String[] args) {
    String string1 = "1";
    String string2 = "2";
    String string11 = "11";

    System.out.println(string1.compareTo(string2)); 
    System.out.println(string2.compareTo(string11));// expected -1 returns 1
   // to compare numbers you actually need to do something like this

    int number2 = Integer.valueOf(string1);
    int number11 = Integer.valueOf(string11);

    int compareTo = number2 > number11 ? 1 : (number2 < number11 ? -1 : 0) ;
    System.out.println(compareTo);// prints -1
}

$a = [1 => 'funny', 3 => 'meshgaat', 15 => 'obi', 2 => 'OMER'];  

$b = 'omer';

function checkArr($x,$array)
{
    $arr = array_values($array);
    $arrlength = count($arr);
    $z = strtolower($x);

    for ($i = 0; $i < $arrlength; $i++) {
        if ($z == strtolower($arr[$i])) {
            echo "yes";
        }  
    } 
};

checkArr($b, $a);

Just call dict() on the list of tuples directly

>>> my_list = [('a', 1), ('b', 2)]
>>> dict(my_list)
{'a': 1, 'b': 2}

The solution that worked for me is the following:

var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
]; 

This article simply explains how you can create a windows application with control on the number of its instances or run only single instance. This is very typical need of a business application. There are already lots of other possible solutions to control this.

https://web.archive.org/web/20090205153420/http://www.openwinforms.com/single_instance_application.html

Change padding-bottom , i.e may be the simplest possible way .

A very simple solution is to search your file(s) for non-ascii characters using a regular expression. This will nicely highlight all the spots where they are found with a border.

Search for [^\x00-\x7F] and check the box for Regex.

The result will look like this (in dark mode):

Decoding is redundant

You only had this "error" in the first place, because of a misunderstanding of what's happening.

You get the b because you encoded to utf-8 and now it's a bytes object.

 >> type("text".encode("utf-8"))
 >> <class 'bytes'>

Fixes:

1. You can just print the string first
2. Redundantly decode it after encoding

Adding to @rybo111's solution, here's what a LinkedIn share would be:

<a href="http://www.linkedin.com/shareArticle?mini=true&url={articleUrl}&title={articleTitle}&summary={articleSummary}&source={articleSource}" target="_blank" class="share-popup">Share on LinkedIn</a>

and add this to your Javascript:

case "www.linkedin.com":
    window_size = "width=570,height=494";
    break;

As per the LinkedIn documentation: https://developer.linkedin.com/docs/share-on-linkedin (See "Customized Url" section)

For anyone who's interested, I used this in a Rails app with a LinkedIn logo, so here's my code if it might help:

<%= link_to image_tag('linkedin.png', size: "50x50"), "http://www.linkedin.com/shareArticle?mini=true&url=#{job_url(@job)}&title=#{full_title(@job.title).html_safe}&summary=#{strip_tags(@job.description)}&source=SOURCE_URL", class: "share-popup" %>

AFAIK the files in the assets directory don't get unpacked. Instead, they are read directly from the APK (ZIP) file.

So, you really can't make stuff that expects a file accept an asset 'file'.

Instead, you'll have to extract the asset and write it to a seperate file, like Dumitru suggests:

  File f = new File(getCacheDir()+"/m1.map");
  if (!f.exists()) try {

    InputStream is = getAssets().open("m1.map");
    int size = is.available();
    byte[] buffer = new byte[size];
    is.read(buffer);
    is.close();


    FileOutputStream fos = new FileOutputStream(f);
    fos.write(buffer);
    fos.close();
  } catch (Exception e) { throw new RuntimeException(e); }

  mapView.setMapFile(f.getPath());

curl -H "Jenkins-Crumb: <your_crumb_data>" -u "<username>:<password>" "http://<your_jenkins_url>?buildWithParameters?token=<your_remote_api_name>?<parameterA>=<val_parameter_A>&<parameterB>=<val_parameterB>"

You can change following parameters as you want:

<your_crumb_data>
<username>
<password>
<your_jenkins_url>
<your_remote_api_name>
<parameterA>
<parameterB>
<val_parameter_A>
<val_parameter_B>

Note: Placing double quotes may be critical. Pay attention, please.

If the link should only change the location if the function run is successful, then do onclick="return runMyFunction();" and in the function you would return true or false.

If you just want to run the function, and then let the anchor tag do its job, simply remove the return false statement.

As a side note, you should probably use an event handler instead, as inline JS isn't a very optimal way of doing things.

1. Click "Utilities and more" near the upper right corner of the screen after choosing your project
2. Choose "Project settings" from the drop down of the "Utilities and more" icon.

Now you may see trash icon and DELETE PROJECT button.

try the following code:

sort() was deprecated for DataFrames in favor of either:

• sort_values() to sort by column(s)
• sort_index() to sort by the index

sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).

I find the following useful and has the following features :

• Throws on null or white space
• Takes multiple params parameter for multiple Url segments
• throws on null or empty

Class

public static class UrlPath
{
   private static string InternalCombine(string source, string dest)
   {
      if (string.IsNullOrWhiteSpace(source))
         throw new ArgumentException("Cannot be null or white space", nameof(source));

      if (string.IsNullOrWhiteSpace(dest))
         throw new ArgumentException("Cannot be null or white space", nameof(dest));

      return $"{source.TrimEnd('/', '\\')}/{dest.TrimStart('/', '\\')}";
   }

   public static string Combine(string source, params string[] args) 
       => args.Aggregate(source, InternalCombine);
}

Tests

UrlPath.Combine("test1", "test2");
UrlPath.Combine("test1//", "test2");
UrlPath.Combine("test1", "/test2");

// Result = test1/test2

UrlPath.Combine(@"test1\/\/\/", @"\/\/\\\\\//test2", @"\/\/\\\\\//test3\") ;

// Result = test1/test2/test3

UrlPath.Combine("/test1/", "/test2/", null);
UrlPath.Combine("", "/test2/");
UrlPath.Combine("/test1/", null);

// Throws an ArgumentException

Key Points About Abstract Class

1. An abstract class cannot be instantiated.
2. An abstract class can have constructor and destructor.
3. An abstract class cannot be a sealed class because the sealed modifier prevents a class from being inherited.
4. An abstract class contains abstract as well as non-abstract members.
5. An abstract class members can be private, protected and internal.
6. Abstract members cannot have a private access modifier.
7. Abstract members are implicitly virtual and must be implemented by a non-abstract derived class.

use zip

columns = zip(*rows) #transpose rows to columns
print columns[0] #print the first column
#you can also do more with the columns
print columns[1] # or print the second column
columns.append([7,7,7]) #add a new column to the end
backToRows = zip(*columns) # now we are back to rows with a new column
print backToRows

you can also use numpy

a = numpy.array(a)
print a[:,0]

Edit: zip object is not subscriptable. It need to be converted to list to access as list:

column = list(zip(*row))

The solution I find is to use custom action Layout: Here is XML for menu.

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:Eventapp="http://schemas.android.com/apk/res-auto">
<!-- This is a comment. -->
    <item
        android:id="@+id/action_create"
        android:actionLayout="@layout/action_view_details_layout"
        android:orderInCategory="50"
        android:showAsAction = "always"/>
</menu>

The Layout is

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="5dp"
    android:gravity="center"
    android:text="@string/create"/>

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:gravity="center"
    android:src="@drawable/ic_action_v"/>

</LinearLayout>

this will show the icon and the text together.

To get the clickitem the the fragment or activity:

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
    //super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_details_fragment, menu);
    View view = menu.findItem(R.id.action_create).getActionView();
    view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(), "Clicked", Toast.LENGTH_SHORT).show();
        }
    });
}

Considering that you are using OpenCV, the best way to convert between data types is to use normalize function.

img_n = cv2.normalize(src=img, dst=None, alpha=0, beta=255, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_8U)

However, if you don't want to use OpenCV, you can do this in numpy

def convert(img, target_type_min, target_type_max, target_type):
    imin = img.min()
    imax = img.max()

    a = (target_type_max - target_type_min) / (imax - imin)
    b = target_type_max - a * imax
    new_img = (a * img + b).astype(target_type)
    return new_img

And then use it like this

imgu8 = convert(img16u, 0, 255, np.uint8)

This is based on the answer that I found on crossvalidated board in comments under this solution https://stats.stackexchange.com/a/70808/277040

I've just had the same problem on a CentOS 7 box.

Seems I'd hit selinux. Putting selinux into permissive mode (setenforce permissive) has worked round the problem for now. I'll try and get back with a proper fix.

INSERT INTO def (field_1, field_2, field3) 
VALUES 
('$field_1', (SELECT id_user from user_table where name = 'jhon'), '$field3')

Use keyup instead of keypress. This gets all the key codes when the user presses something

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL

delete from employee where rowid in (select rowid from (select rowid, name_count from (select rowid, count(emp_name) as name_count from employee group by emp_id, emp_name) where name_count>1))

add this to your coursel div :

data-interval="false"

There's a plugin that detects up/down mouse wheel and velocity over a region.

You can implement this with a new Html helper extension function which will then be used similarly to the existing ActionLinks.

public static MvcHtmlString ActionLinkHtml5Data(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes, object htmlDataAttributes)
{
    if (string.IsNullOrEmpty(linkText))
    {
        throw new ArgumentException(string.Empty, "linkText");
    }

    var html = new RouteValueDictionary(htmlAttributes);
    var data = new RouteValueDictionary(htmlDataAttributes);

    foreach (var attributes in data)
    {
        html.Add(string.Format("data-{0}", attributes.Key), attributes.Value);
    }

    return MvcHtmlString.Create(HtmlHelper.GenerateLink(htmlHelper.ViewContext.RequestContext, htmlHelper.RouteCollection, linkText, null, actionName, controllerName, new RouteValueDictionary(routeValues), html));
}

And you call it like so ...

<%: Html.ActionLinkHtml5Data("link display", "Action", "Controller", new { id = Model.Id }, new { @class="link" }, new { extra = "some extra info" })  %>

Simples :-)

edit

bit more of a write up here

Are you looking for a pure bash solution? There are many approaches, but here's one.

for file in *_h.png ; do mv "$file" "${file%%_h.png}_half.png" ; done

This presumes that the only files in the current directory that end in _h.png are the ones you want to rename.

Much more specifically

for file in 0{5..6}_h.png ; do mv "$file" "${file/_h./_half.}" ; done

Presuming those two examples are your only. files.

For the general case, file renaming in has been covered before.

I know its Too late But I hope it will work new comers Try This Its Working ... :D

First, install the URL Rewrite from a download or from the Web Platform Installer. Second, restart IIS. And, finally, close IIS and open again. The last step worked for me.

Sample code you can use to let Tika take care of container files for you. http://wiki.apache.org/tika/RecursiveMetadata

Form what I can tell, the accepted solution will not work for cases where there are nested zip files. Tika, however will take care of such situations as well.

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

The way that setuptools does it, it uses the pkg_resources.parse_version function. It should be PEP440 compliant.

Example:

#! /usr/bin/python
# -*- coding: utf-8 -*-
"""Example comparing two PEP440 formatted versions
"""
import pkg_resources

VERSION_A = pkg_resources.parse_version("1.0.1-beta.1")

Why Encapsulation? Why Abstraction?

lets start with the question below:

1)What happens if we allow code to directly access field ? (directly allowing means making field public)

lets understand this with an example,

following is our BankAccount class and following is its limitation
*Limitation/Policy* : Balance in BankAccount can not be more than 50000Rs. (This line 
 is very important to understand)

class BankAccount
{
   **public** double balanceAmount;
}

Following is **AccountHolder**(user of BankAccount) class which is consumer of 
**BankAccount** class.

class AccountHolder
{
   BankAccount mybankAccount = new BankAccount();

   DoAmountCreditInBankAccount()
   {
       mybankAccount.balanceAmount = 70000; 
      /* 
       this is invalid practice because this statement violates policy....Here 
       BankAccount class is not able to protect its field from direct access
       Reason for direct access by acount holder is that balanceAmount directly 
       accessible due to its public access modifier. How to solve this issue and 
       successfully implement BankAccount Policy/Limitation. 
      */
   }
}

if some other part of code directly access balanceAmount field and set balance amount to 70000Rs which is not acceptable. Here in this case we can not prevent some other part of code from accessing balanceAmount field.

So what we can do?

=> Answer is we can make balanceAmount field private so that no other code can directly access it and allowing access to that field only via public method which operates on balanceAmount field. Main role of method is that we can write some prevention logic inside method so that field can not be initialized with more than 50000Rs. Here we are making binding between data field called balanceAmount and method which operates on that field. This process is called Encapsulation.(it is all about protecting fields using access modifier such as private)

Encapsulation is one way to achieve abstraction....but How? => User of this method will not know about implementation (How amount gets credited? logic and all that stuff) of method which he/she will invoke. Not knowing about implementation details by user is called Abstraction(Hiding details from user).

Following will be the implementation of class:

class BankAccount
{
   **private** double balanceAmount;

   **public** void UpdateBankBalance(double amount)
   {
    if(balanceAmount + amount > 50000)
    {
       Console.WriteLine("Bank balance can not be more than 50000, Transaction can 
                          not be proceed");
    }
    else
    {
       balanceAmount = balanceAmount + amount;
           Console.WriteLine("Amount has been credited to your bank account 
                              successfully.....");
    }
   }
}


class AccountHolder
{
   BankAccount mybankAccount = new BankAccount();

   DoAmountCreditInBankAccount()
   {
      mybankAccount.UpdateBankBalance(some_amount);
      /*
       mybankAccount.balanceAmount will not be accessible due to its protection level 
       directly from AccountHolder so account holder will consume BankAccount public 
       method UpdateBankBalance(double amount) to update his/her balance.
      */
   }
}

Thanks to Dzmitry Lahoda!

Well in general index is a B-tree. There are two types of indexes: clustered and nonclustered.

Clustered index creates a physical order of rows (it can be only one and in most cases it is also a primary key - if you create primary key on table you create clustered index on this table also).

Nonclustered index is also a binary tree but it doesn't create a physical order of rows. So the leaf nodes of nonclustered index contain PK (if it exists) or row index.

Indexes are used to increase the speed of search. Because the complexity is of O(log N). Indexes is very large and interesting topic. I can say that creating indexes on large database is some kind of art sometimes.

In my case, I was using a service in a sub module (NOT the root AppModule), and the HttpClientModule was imported only in the module.

So I have to modify the default scope of the service, by changing 'providedIn' to 'any' in the @Injectable decorator.

By default, if you using angular-cli to generate the service, the 'providedIn' was set to 'root'.

Hope this helps.

You might want to check your CSS. In the example here: https://css-tricks.com/the-checkbox-hack/ there's position: absolute; top: -9999px;. This is particularly goofy on Chrome, as onclick="whatever" still jumps to the absolute position of the clicked element.

Removing position: absolute; top: -9999px;, for display: none; might help.

It seem that w3c switched it to font/woff2

I see there is some discussion about the proper mime type. In the link we read:

This document defines a top-level MIME type "font" ...

... the officially defined IANA subtypes such as "application/font-woff" ...

The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.

and later

6.5. WOFF 2.0

    Type name:

        font
    Subtype name:

        woff2

So proposition from W3C differs from IANA.

We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:

Type name:

    application
Subtype name:

    font-woff

which is

application/font-woff
