If you are using office 365 follow this steps:

1. check the password expiration time using Azure power shell :Get-MsolUser -All | select DisplayName, LastPasswordChangeTimeStamp
2. Change the password using a new password (not the old one). You can eventually go back to the old password but you need to change it twice.

Hope it helps!

Update: Data Classes

With the introduction of Data Classes in Python 3.7 we get very close.

The following example is similar to the NamedTuple example below, but the resulting object is mutable and it allows for default values.

from dataclasses import dataclass


@dataclass
class Point:
    x: float
    y: float
    z: float = 0.0


p = Point(1.5, 2.5)

print(p)  # Point(x=1.5, y=2.5, z=0.0)

This plays nicely with the new typing module in case you want to use more specific type annotations.

I've been waiting desperately for this! If you ask me, Data Classes and the new NamedTuple declaration, combined with the typing module are a godsend!

Improved NamedTuple declaration

Since Python 3.6 it became quite simple and beautiful (IMHO), as long as you can live with immutability.

A new way of declaring NamedTuples was introduced, which allows for type annotations as well:

from typing import NamedTuple


class User(NamedTuple):
    name: str


class MyStruct(NamedTuple):
    foo: str
    bar: int
    baz: list
    qux: User


my_item = MyStruct('foo', 0, ['baz'], User('peter'))

print(my_item) # MyStruct(foo='foo', bar=0, baz=['baz'], qux=User(name='peter'))

I don't think you should be returning any http error codes, rather custom exceptions that are useful to the client end of the application so the interface knows what had actually occurred. I wouldn't try and mask real issues with 404 error codes or something to that nature.

What is the type of c.PhysicalAddresses? If it's Dictionary<TKey,TValue>, then you can use the ContainsKey method.

System.out.println(myList.size());

Since no elements are in the list

output => 0

myList.add("newString");  // use myList.add() to insert elements to the arraylist
System.out.println(myList.size());

Since one element is added to the list

output => 1

The key is "argument-less git-pull". When you do a git pull from a branch, without specifying a source remote or branch, git looks at the branch.<name>.merge setting to know where to pull from. git push -u sets this information for the branch you're pushing.

To see the difference, let's use a new empty branch:

$ git checkout -b test

First, we push without -u:

$ git push origin test
$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.test.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "test"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.

Now if we add -u:

$ git push -u origin test
Branch test set up to track remote branch test from origin.
Everything up-to-date
$ git pull
Already up-to-date.

Note that tracking information has been set up so that git pull works as expected without specifying the remote or branch.

Update: Bonus tips:

• As Mark mentions in a comment, in addition to git pull this setting also affects default behavior of git push. If you get in the habit of using -u to capture the remote branch you intend to track, I recommend setting your push.default config value to upstream.
• git push -u <remote> HEAD will push the current branch to a branch of the same name on <remote> (and also set up tracking so you can do git push after that).

you must use import android.support.v7.app.ActionBarDrawerToggle;

and use the constructor

public CustomActionBarDrawerToggle(Activity mActivity,DrawerLayout mDrawerLayout)
{
    super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
}

and if the drawer toggle button becomes dark then you must use the supportActionBar provided in the support library.

You can implement supportActionbar from this link: http://developer.android.com/training/basics/actionbar/setting-up.html

this code adds horizontal line to a linear layout

View view = new View(this);
LinearLayout.LayoutParams lpView = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 1); // --> horizontal
view.setLayoutParams(lpView);
view.setBackgroundColor(Color.DKGRAY);

linearLayout.addView(view);

It really depends on what level you mean. In Python 2.x, there are two integer types, int (constrained to sys.maxint) and long (unlimited precision), for historical reasons. In Python code, this shouldn't make a bit of difference because the interpreter automatically converts to long when a number is too large. If you want to know about the actual data types used in the underlying interpreter, that's implementation dependent. (CPython's are located in Objects/intobject.c and Objects/longobject.c.) To find out about the systems types look at cdleary answer for using the struct module.

In Python, the 'null' object is the singleton None.

The best way to check things for "Noneness" is to use the identity operator, is:

if foo is None:
    ...

You don't want to stretch the span in height?
You have the possiblity to affect one or more flex-items to don't stretch the full height of the container.

To affect all flex-items of the container, choose this:
You have to set align-items: flex-start; to div and all flex-items of this container get the height of their content.

div {_x000D_
  align-items: flex-start;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}

<div>_x000D_
  <span>This is some text.</span>_x000D_
</div>

To affect only a single flex-item, choose this:
If you want to unstretch a single flex-item on the container, you have to set align-self: flex-start; to this flex-item. All other flex-items of the container aren't affected.

div {_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
  background: tan;_x000D_
}_x000D_
span.only {_x000D_
  background: red;_x000D_
  align-self:flex-start;_x000D_
}_x000D_
span {_x000D_
    background:green;_x000D_
}

<div>_x000D_
  <span class="only">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

Why is this happening to the span?
The default value of the property align-items is stretch. This is the reason why the span fill the height of the div.

Difference between baseline and flex-start?
If you have some text on the flex-items, with different font-sizes, you can use the baseline of the first line to place the flex-item vertically. A flex-item with a smaller font-size have some space between the container and itself at top. With flex-start the flex-item will be set to the top of the container (without space).

div {_x000D_
  align-items: baseline;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}_x000D_
span.fontsize {_x000D_
  font-size:2em;_x000D_
}

<div>_x000D_
  <span class="fontsize">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

You can find more information about the difference between baseline and flex-start here:
What's the difference between flex-start and baseline?

Maybe you included the .c file in makefile multiple times.

A naming convention like this is useful when you are reading code, particularly code that is not your own. A strong naming convention helps indicate where a particular member is defined, what kind of member it is, etc. Most development teams adopt a simple naming convention, and simply prefix member fields with an underscore (_fieldName). In the past, I have used the following naming convention for C# (which is based on Microsofts conventions for the .NET framework code, which can be seen with Reflector):

Instance Field: m_fieldName
Static Field: s_fieldName
Public/Protected/Internal Member: PascalCasedName()
Private Member: camelCasedName()

This helps people understand the structure, use, accessibility and location of members when reading unfamiliar code very rapidly.

I'm setting up a dev server to play with that mirrors our outdated live one, I used The Perfect Server - Ubuntu 14.04 (nginx, BIND, MySQL, PHP, Postfix, Dovecot and ISPConfig 3)

After experiencing the same issue, I came across this post and nothing was working. I changed the value in every recommended file (nginx.conf, ispconfig.vhost, /sites-available/default, etc.)

Finally, changing client_max_body_size in my /etc/nginx/sites-available/apps.vhost and restarting nginx is what did the trick. Hopefully it helps someone else.

Seeing as this is the top result on Google for "static class java" and the best answer isn't here I figured I'd add it. I'm interpreting OP's question as concerning static classes in C#, which are known as singletons in the Java world. For those unaware, in C# the "static" keyword can be applied to a class declaration which means the resulting class can never be instantiated.

Excerpt from "Effective Java - Second Edition" by Joshua Bloch (widely considered to be one of the best Java style guides available):

As of release 1.5, there is a third approach to implementing singletons. Simply make an enum type with one element:

// Enum singleton - the preferred approach
public enum Elvis {
    INSTANCE;
    public void leaveTheBuilding() { ... }
}

This approach is functionally equivalent to the public field approach, except that it is more concise, provides the serialization machinery for free , and provides an ironclad guarantee against multiple instantiation, even in the face of sophisticated serialization or reflection attacks. While this approach has yet to be widely adopted, a single-element enum type is the best way to implement a singleton. (emphasis author's)

Bloch, Joshua (2008-05-08). Effective Java (Java Series) (p. 18). Pearson Education.

I think the implementation and justification are pretty self explanatory.

You need to write it this way

<div 
    className="player"
    style={{ position: "absolute" }}
    onKeyDown={this.onKeyPressed}
    tabIndex="0"
  >

If onKeyPressed is not bound to this, then try to rewrite it using arrow function or bind it in the component constructor.

For windows machine: After trying alot of set path, remove path and etc. What finally work is to located the folder C:\Users\johndoe\.android and delete it. after that you can lunch your Android Studio, it will ask you to download and install a new AVD and it will override and create a fresh new folder and files. This solve the problem.

Just increasing max_connections is bad idea. You need to increase shared_buffers and kernel.shmmax as well.

Considerations

max_connections determines the maximum number of concurrent connections to the database server. The default is typically 100 connections.

Before increasing your connection count you might need to scale up your deployment. But before that, you should consider whether you really need an increased connection limit.

Each PostgreSQL connection consumes RAM for managing the connection or the client using it. The more connections you have, the more RAM you will be using that could instead be used to run the database.

A well-written app typically doesn't need a large number of connections. If you have an app that does need a large number of connections then consider using a tool such as pg_bouncer which can pool connections for you. As each connection consumes RAM, you should be looking to minimize their use.

How to increase max connections

1. Increase max_connection and shared_buffers

in /var/lib/pgsql/{version_number}/data/postgresql.conf

change

max_connections = 100
shared_buffers = 24MB

to

max_connections = 300
shared_buffers = 80MB

The shared_buffers configuration parameter determines how much memory is dedicated to PostgreSQL to use for caching data.

• If you have a system with 1GB or more of RAM, a reasonable starting value for shared_buffers is 1/4 of the memory in your system.
• it's unlikely you'll find using more than 40% of RAM to work better than a smaller amount (like 25%)
• Be aware that if your system or PostgreSQL build is 32-bit, it might not be practical to set shared_buffers above 2 ~ 2.5GB.
• Note that on Windows, large values for shared_buffers aren't as effective, and you may find better results keeping it relatively low and using the OS cache more instead. On Windows the useful range is 64MB to 512MB.

2. Change kernel.shmmax

You would need to increase kernel max segment size to be slightly larger than the shared_buffers.

In file /etc/sysctl.conf set the parameter as shown below. It will take effect when postgresql reboots (The following line makes the kernel max to 96Mb)

kernel.shmmax=100663296

Darin Dimitrov's answer shows that OrderBy is slightly faster than List.Sort when faced with already-sorted input. I modified his code so it repeatedly sorts the unsorted data, and OrderBy is in most cases slightly slower.

Furthermore, the OrderBy test uses ToArray to force enumeration of the Linq enumerator, but that obviously returns a type (Person[]) which is different from the input type (List<Person>). I therefore re-ran the test using ToList rather than ToArray and got an even bigger difference:

Sort: 25175ms
OrderBy: 30259ms
OrderByWithToList: 31458ms

Table2.Column2 => Table1.Column1

I realize this question is old but the accepted answer did not work for me. For future googlers, this is what worked for me:

UPDATE table1 
    SET column1 = (
        SELECT column2
        FROM table2
        WHERE table2.id = table1.id
    );

Whereby:

• table1 = table that has the column that needs to be updated
• table2 = table that has the column with the data
• column1 = blank column that needs the data from column2 (this is in table1)
• column2 = column that has the data (that is in table2)

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

In response to the good solution from macek. The solution didn't work for me. I have to bind the values of the datas to the export function. This solution works for me:

function exportToForm(a, b, c, d, e) {
  console.log(a, b, c, d, e);
}

var images = document.getElementsByTagName("img");

for (var i=0, len=images.length, img; i<len; i++) {
  var img = images[i];
  var boundExportToForm = exportToForm.bind(undefined, 
          img.getAttribute("data-a"), 
            img.getAttribute("data-b"),
            img.getAttribute("data-c"),
            img.getAttribute("data-d"),
            img.getAttribute("data-e"))

  img.addEventListener("click", boundExportToForm);
  }

Generally the most common mistake is not cleaning your build directory after adding new options. I have Boost installed from system packet manager. Its version is 1.49.

I also downloaded Boost 1.53 and "installed" it under $HOME/installs.

The only thing that I had to do in my project was to (I keep sources in my_project_directory/src):

cd my_project_directory
mkdir build
cd build
cmake -DCMAKE_INCLUDE_PATH=$HOME/installs/include -DCMAKE_LIBRARY_PATH=$HOME/installs/lib ../src

And that's it. Ta bum tss.

But if I'd make after cd build -> cmake ../src it would set Boost from the system path. Then doing cmake -DCMAKE_INCLUDE_PATH=$HOME/installs/include -DCMAKE_LIBRARY_PATH=$HOME/installs/lib ../src would change nothing.

You have to clean your build directory ( cd build && rm -rf * ;) )

__all__ is used to document the public API of a Python module. Although it is optional, __all__ should be used.

Here is the relevant excerpt from the Python language reference:

The public names defined by a module are determined by checking the module’s namespace for a variable named __all__; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ('_'). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module).

PEP 8 uses similar wording, although it also makes it clear that imported names are not part of the public API when __all__ is absent:

To better support introspection, modules should explicitly declare the names in their public API using the __all__ attribute. Setting __all__ to an empty list indicates that the module has no public API.

[...]

Imported names should always be considered an implementation detail. Other modules must not rely on indirect access to such imported names unless they are an explicitly documented part of the containing module's API, such as os.path or a package's __init__ module that exposes functionality from submodules.

Furthermore, as pointed out in other answers, __all__ is used to enable wildcard importing for packages:

The import statement uses the following convention: if a package’s __init__.py code defines a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered.

//This is to convert a letter from upper case to lower case
import java.util.Scanner;
    public class ChangeCase {
        public static void main(String[]args) {

            String input;
            Scanner sc= new Scanner(System.in);
                System.out.println("Enter Letter from upper case");
                input=sc.next();

            String result;
            result= input.toLowerCase();
            System.out.println(result);
        }
    }

This is an old question and asks a little bit less than what I needed so this answer actually solves more than this question asks. The answers in this question helped me solve the following:

1. (asked) Record differences between two dictionaries
2. Merge differences from #1 into base dictionary
3. (asked) Merge differences between two dictionaries (treat dictionary #2 as if it were a diff dictionary)
4. Try to detect item movements as well as changes
5. (asked) Do all of this recursively

All this combined with JSON makes for a pretty powerful configuration storage support.

You can generate scripts to a file via SQL Server Management Studio, here are the steps:

1. Right click the database you want to generate scripts for (not the table) and select tasks - generate scripts
2. Next, select the requested table/tables, views, stored procedures, etc (from select specific database objects)
3. Click advanced - select the types of data to script
4. Click Next and finish

MSDN Generate Scripts

When generating the scripts, there is an area that will allow you to script, constraints, keys, etc. From SQL Server 2008 R2 there is an Advanced Option under scripting:

In my opinion the most readable version

public enum PIN_PULL_RESISTANCE {
    PULL_UP {
        @Override
        public int getValue() {
            return 1;
        }
    },
    PULL_DOWN {
        @Override
        public int getValue() {
            return 0;
        }
    };

    public abstract int getValue();
}

I hope to provide more background knowledge here.

First, constructor signature of the of method threading::Thread:

class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)

args is the argument tuple for the target invocation. Defaults to ().

Second, A quirk in Python about tuple:

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).

On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'. So if send a string to args, even in parentheses (still a sting), each character will be treated as a single parameter.

However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError to complain.

To make sure it does not fail for string, date and timestamp columns:

import pyspark.sql.functions as F
def count_missings(spark_df,sort=True):
    """
    Counts number of nulls and nans in each column
    """
    df = spark_df.select([F.count(F.when(F.isnan(c) | F.isnull(c), c)).alias(c) for (c,c_type) in spark_df.dtypes if c_type not in ('timestamp', 'string', 'date')]).toPandas()

    if len(df) == 0:
        print("There are no any missing values!")
        return None

    if sort:
        return df.rename(index={0: 'count'}).T.sort_values("count",ascending=False)

    return df

If you want to see the columns sorted based on the number of nans and nulls in descending:

count_missings(spark_df)

# | Col_A | 10 |
# | Col_C | 2  |
# | Col_B | 1  | 

If you don't want ordering and see them as a single row:

count_missings(spark_df, False)
# | Col_A | Col_B | Col_C |
# |  10   |   1   |   2   |

you may also place the followinng

<a href='javascript:alert("hello world!");'>Click me</a>

to your html-code, and when you click on 'Click me' hyperlink, javascript will appear in url-bar and Alert dialog will show

String str="004-034556"
String[] sTemp=str.split("-");// '-' is a delimiter

string1=004 // sTemp[0];
string2=034556//sTemp[1];

For me it was becuase I recently added

One of the reasons that C++ was designed was to make it easy to reuse code. In general, C++ should be written so that it works whether the class is instantiated on the heap, in an array, or on the stack. "Delete this" is a very bad coding practice because it will only work if a single instance is defined on the heap; and there had better not be another delete statement, which is typically used by most developers to clean up the heap. Doing this also assumes that no maintenance programmer in the future will cure a falsely perceived memory leak by adding a delete statement.

Even if you know in advance that your current plan is to only allocate a single instance on the heap, what if some happy-go-lucky developer comes along in the future and decides to create an instance on the stack? Or, what if he cuts and pastes certain portions of the class to a new class that he intends to use on the stack? When the code reaches "delete this" it will go off and delete it, but then when the object goes out of scope, it will call the destructor. The destructor will then try to delete it again and then you are hosed. In the past, doing something like this would screw up not only the program but the operating system and the computer would need to be rebooted. In any case, this is highly NOT recommended and should almost always be avoided. I would have to be desperate, seriously plastered, or really hate the company I worked for to write code that did this.

Easiest way:

+num.toFixed(2)

It converts it to a string, and then back into an integer / float.

Simple example in java

public class Driver {

  static int x;
  static int y;

public static void main(String[] args) 
throws Exception {

System.out.println("using double pipe");
    if(setX() || setY())
        {System.out.println("x = "+x);
        System.out.println("y = "+y);
        }



System.out.println("using single pipe");
if(setX() | setY())
    {System.out.println("x = "+x);
    System.out.println("y = "+y);
    }

}

 static boolean setX(){
      x=5;
     return true;
  }
 static boolean setY(){
      y=5;
      return true;
  }
}

output :

using double pipe
x = 5
y = 0
using single pipe
x = 5
y = 5

For the toast message in flutter use bot_toast library. This library provides Feature-rich, support for displaying notifications, text, loading, attachments, etc. Toast

Here is simple code. You must set an id for your input. Here call it 'myInput':

var myform = document.getElementById('myform');
myform.onsubmit = function(){
    document.getElementById('myInput').value = '1';
    myform.submit();
};

There are five ways to convert The First Way :

String str = " 123" ;
int i = Integer.parse(str); 
output : 123

The second way :

String str = "hello123world";
int i = Integer.parse(str.replaceAll("[\\D]" , "" ) );
output : 123

The Third Way :

String str"123";
int i = new Integer(str);
output "123 

The Fourth Way :

String str"123";
int i = Integer.valueOf(Str);
output "123 

The Fifth Way :

String str"123";
int i = Integer.decode(str);
output "123 

There could be other ways But that's what I remember now

Normally you would select IDs using the ID selector #, but for more complex matches you can use the attribute-starts-with selector (as a jQuery selector, or as a CSS3 selector):

div[id^="player_"]

If you are able to modify that HTML, however, you should add a class to your player divs then target that class. You'll lose the additional specificity offered by ID selectors anyway, as attribute selectors share the same specificity as class selectors. Plus, just using a class makes things much simpler.

Many description internet-wide don't mention that specifying Access-Control-Allow-Origin is not enough. Here is a complete example that works for me:

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Methods: POST, GET, DELETE, PUT, PATCH, OPTIONS');
        header('Access-Control-Allow-Headers: token, Content-Type');
        header('Access-Control-Max-Age: 1728000');
        header('Content-Length: 0');
        header('Content-Type: text/plain');
        die();
    }

    header('Access-Control-Allow-Origin: *');
    header('Content-Type: application/json');

    $ret = [
        'result' => 'OK',
    ];
    print json_encode($ret);

To kill with grep:

kill -9 `pgrep myprocess`

Imo, you should try MySQL Connector/Node.js which is the official Node.js driver for MySQL. See ref-1 and ref-2 for detailed explanation. I have tried mysqljs/mysql which is available here, but I don't find detailed documentation on classes, methods, properties of this library.

So I switched to the standard MySQL Connector/Node.js with X DevAPI, since it is an asynchronous Promise-based client library and provides good documentation. Take a look at the following code snippet :

const mysqlx = require('@mysql/xdevapi');
const rows = [];

mysqlx.getSession('mysqlx://localhost:33060')
.then(session => {
    const table = session.getSchema('testSchema').getTable('testTable');

    // The criteria is defined through the expression.
    return table.update().where('name = "bar"').set('age', 50)
        .execute()
        .then(() => {
            return table.select().orderBy('name ASC')
                .execute(row => rows.push(row));
        });
})
.then(() => {
    console.log(rows);
});

Recursion occurs when something contains, or uses, a similar version of itself.When talking specifically about computer programming, recursion occurs when a function calls itself.

The following link helps me to understand recursion better, even I consider this is the best so far what I've learned.

It comes with an example to understand how the inner(recursive) functions called while executing.

Please go through the article and I have pasted the test program in case if the article got trashed. You may please run the program in local server to see it in action.

https://www.elated.com/php-recursive-functions/

<?php

function factorial( $n ) {

  // Base case
  if ( $n == 0 ) {
    echo "Base case: $n = 0. Returning 1...<br>";
    return 1;
  }

  // Recursion
  echo "$n = $n: Computing $n * factorial( " . ($n-1) . " )...<br>";
  $result = ( $n * factorial( $n-1 ) );
  echo "Result of $n * factorial( " . ($n-1) . " ) = $result. Returning $result...<br>";
  return $result;
}

echo "The factorial of 5 is: " . factorial( 5 );

?>

My "convention": static before instance, public before private, constructor before methods, but main method at the bottom (if present).

Best way to find this is: create a php file and add the following code:

<?php phpinfo(); ?>

and open it in browser, it will show the file which is actually being read!

Updates by OP:

1. The previously accepted answer is likely to be faster and more convenient for you, but it is not always correct. See comments on that answer.
2. Please also note the more convenient alternative <?php echo php_ini_loaded_file(); ?> mentioned in this answer.

A relatively easy way of doing this is to write the entire sequence as a shell script.

out.tar:
   set -e ;\
   TMP=$$(mktemp -d) ;\
   echo hi $$TMP/hi.txt ;\
   tar -C $$TMP cf $@ . ;\
   rm -rf $$TMP ;\

You can use Replace Function to replace comma easily. To Do this-

The syntax for the REPLACE function in SQL Server (Transact-SQL) is:
REPLACE( string, string_to_replace, replacement_string )

Parameters or Arguments

string : The source string from which a sequence of characters will be replaced by another set of characters.
string_to_replace : The string that will be searched for in string1.
replacement_string : The replacement string. All occurrences of string_to_replace will be replaced with replacement_string in string1.
Note :

The REPLACE function performs a replacement that is not case-sensitive. So all occurrences of string_to_replace will be replaced with replacement_string regardless of the case of string_to_replace or replacement_string

For Example :
SELECT REPLACE('Kapil,raj,chouhan', ',' , ' ') from DUAL;
Result : Kapil raj chouhan

SELECT REPLACE('I Live In India', ' ' , '-') from DUAL;
Result : I-Live-In-India

SELECT REPLACE('facebook.com', 'face' , 'friends') from DUAL;
Result : friendsbook.com

I Hope it will be usefull for you.

Logic index:

d<-d[!(d$A=="B" & d$E==0),]

In the majority of project there are some implementation of object extending: underscore, jquery, lodash: extend.

There is also pure javascript implementation, that is a part of ECMAscript 6: Object.assign: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign

Adding my 2 cents .If you are using scala and sbt and scala-logging as dependency ;then this can happen because scala-logging's earlier version had the name scala-logging-api.So;essentially the dependency resolutions do not happen because of different names leading to runtime errors while launching the scala application.

Base class constructors are automatically called for you if they have no argument. If you want to call a superclass constructor with an argument, you must use the subclass's constructor initialization list. Unlike Java, C++ supports multiple inheritance (for better or worse), so the base class must be referred to by name, rather than "super()".

class SuperClass
{
    public:

        SuperClass(int foo)
        {
            // do something with foo
        }
};

class SubClass : public SuperClass
{
    public:

        SubClass(int foo, int bar)
        : SuperClass(foo)    // Call the superclass constructor in the subclass' initialization list.
        {
            // do something with bar
        }
};

More info on the constructor's initialization list here and here.

Perhaps your Apache is bounded to localhost only. Look in your apache configuration file for:

Listen 127.0.0.1:80

If you found it, replace it for:

Listen 80

With GNU Make, you can use shell and eval to store, run, and assign output from arbitrary command line invocations. The difference between the example below and those which use := is the := assignment happens once (when it is encountered) and for all. Recursively expanded variables set with = are a bit more "lazy"; references to other variables remain until the variable itself is referenced, and the subsequent recursive expansion takes place each time the variable is referenced, which is desirable for making "consistent, callable, snippets". See the manual on setting variables for more info.

# Generate a random number.
# This is not run initially.
GENERATE_ID = $(shell od -vAn -N2 -tu2 < /dev/urandom)

# Generate a random number, and assign it to MY_ID
# This is not run initially.
SET_ID = $(eval MY_ID=$(GENERATE_ID))

# You can use .PHONY to tell make that we aren't building a target output file
.PHONY: mytarget
mytarget:
# This is empty when we begin
    @echo $(MY_ID)
# This recursively expands SET_ID, which calls the shell command and sets MY_ID
    $(SET_ID)
# This will now be a random number
    @echo $(MY_ID)
# Recursively expand SET_ID again, which calls the shell command (again) and sets MY_ID (again)
    $(SET_ID)
# This will now be a different random number
    @echo $(MY_ID)

mime_content_type() appears to be the way to go, notwithstanding the above comments saying it is deprecated. It is not -- or at least this incarnation of mime_content_type() is not deprecated, according to http://php.net/manual/en/function.mime-content-type.php. It is part of the FileInfo extension, but the PHP documentation now tells us it is enabled by default as of PHP 5.3.0.

Use a comma to specify a port number with SQL Server:

mycomputer.test.xxx.com,1234

It's not necessary to specify an instance name when specifying the port.

Lots more examples at http://www.connectionstrings.com/. It's saved me a few times.

How does the server know that it should pull image.png from the /pictures folder when you visit the website and browse to the /system/files/images folder in your web browser? A so-called symbolic link is the guy that is responsible for this behavior. Somewhere in your system, there is a symlink that tells your server "If a visitor requests /system/files/images/image.png then show him /pictures/image.png."

And what is the role of the FollowSymLinks setting in this?

FollowSymLinks relates to server security. When dealing with web servers, you can't just leave things undefined. You have to tell who has access to what. The FollowSymLinks setting tells your server whether it should or should not follow symlinks. In other words, if FollowSymLinks was disabled in our case, browsing to the /system/files/images/image.png file would return depending on other settings either the 403 (access forbidden) or 404 (not found) error.

We can create alternative of implode of in javascript:

function my_implode_js(separator,array){
       var temp = '';
       for(var i=0;i<array.length;i++){
           temp +=  array[i] 
           if(i!=array.length-1){
                temp += separator  ; 
           }
       }//end of the for loop

       return temp;
}//end of the function

var array = new Array("One", "Two", "Three");


var str = my_implode_js('-',array);
alert(str);

You can:

• Either, use an <input type="submit" ..>, instead of that button.
• or, Use a bit of javascript, to get a hold of form object (using name or id), and call submit(..) on it. Eg: form.submit(). Attach this code to the button click event. This will serialise the form parameters and execute a GET or POST request as specified in the form's method attribute.

Likewise, I saw this error as a result of too little RAM. I cranked up the RAM on the VM and the error disappeared.

You could just use VideoLAN. VideoLAN will work as a server (or you can wrap your own C# application around it for more control). There are also .NET wrappers for the viewer that you can use and thus embed in your C# client.

I liked @Andomar's answer best, but I needed the column descriptions also. Here is his query modified to include those also. (Uncomment the last part of the WHERE clause to return only rows where either description is non-null).

SELECT
    TableName = tbl.table_schema + '.' + tbl.table_name, 
    TableDescription = tableProp.value,
    ColumnName = col.column_name, 
    ColumnDataType = col.data_type,
    ColumnDescription = colDesc.ColumnDescription
FROM information_schema.tables tbl
INNER JOIN information_schema.columns col 
    ON col.table_name = tbl.table_name
LEFT JOIN sys.extended_properties tableProp 
    ON tableProp.major_id = object_id(tbl.table_schema + '.' + tbl.table_name) 
        AND tableProp.minor_id = 0
        AND tableProp.name = 'MS_Description' 
LEFT JOIN (
    SELECT sc.object_id, sc.column_id, sc.name, colProp.[value] AS ColumnDescription
    FROM sys.columns sc
    INNER JOIN sys.extended_properties colProp
        ON colProp.major_id = sc.object_id
            AND colProp.minor_id = sc.column_id
            AND colProp.name = 'MS_Description' 
) colDesc
    ON colDesc.object_id = object_id(tbl.table_schema + '.' + tbl.table_name)

--AND tableProp.[value] IS NOT NULL OR colDesc.ColumnDescription IS NOT null

$(this).parent().siblings(":first").text()

parent gives you the <td> around the link,

siblings gives all the <td> tags in that <tr>,

:first gives the first matched element in the set.

text() gives the contents of the tag.

With Chrome and Safari you can add the CSS style -webkit-print-color-adjust: exact; to the element to force print the background color and/or image

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

The raw info is in pg_index.

You can encapsulate your block of code with a try ... catch statement, and when you run your code, if the column doesn't exist it will throw an exception. You can then figure out what specific exception it throws and have it handle that specific exception in a different way if you so desire, such as returning "Column Not Found".

A method that I use is to load the table into R as a data.frame, then use dbWriteTable to push it to PostgreSQL. These two steps are shown below.

Load Excel data into R

R's data.frame objects are database-like, where named columns have explicit types, such as text or numbers. There are several ways to get a spreadsheet into R, such as XLConnect. However, a really simple method is to select the range of the Excel table (including the header), copy it (i.e. CTRL+C), then in R use this command to get it from the clipboard:

d <- read.table("clipboard", header=TRUE, sep="\t", quote="\"", na.strings="", as.is=TRUE)

If you have RStudio, you can easily view the d object to make sure it is as expected.

Push it to PostgreSQL

Ensure you have RPostgreSQL installed from CRAN, then make a connection and send the data.frame to the database:

library(RPostgreSQL)
conn <- dbConnect(PostgreSQL(), dbname="mydb")

dbWriteTable(conn, "some_table_name", d)

Now some_table_name should appear in the database.

Some common clean-up steps can be done from pgAdmin or psql:

ALTER TABLE some_table_name RENAME "row.names" TO id;
ALTER TABLE some_table_name ALTER COLUMN id TYPE integer USING id::integer;
ALTER TABLE some_table_name ADD PRIMARY KEY (id);

an SQL that shows SQL commands, need to run to duplicate a database from one database to another. for each table there is create a table statement and an insert statement. it assumes both databases are on the same server:

select @fromdb:="crm";
select @todb:="crmen";

SET group_concat_max_len=100000000;


SELECT  GROUP_CONCAT( concat("CREATE TABLE `",@todb,"`.`",table_name,"` LIKE `",@fromdb,"`.`",table_name,"`;\n",
"INSERT INTO `",@todb,"`.`",table_name,"` SELECT * FROM `",@fromdb,"`.`",table_name,"`;") 

SEPARATOR '\n\n')

as sqlstatement
 FROM information_schema.tables where table_schema=@fromdb and TABLE_TYPE='BASE TABLE';

.scroll {
   width: 200px; height: 400px;
   overflow: auto;
}

If you want string to be on the left and image on the right, this should be fine (Swift 5)

/// [ String ------------------ Image ] Style Custom Button
/// For use, just define 'Title Text' and 'Image' on ib / source with setting the class 'DistantTextImageButton'.

class DistantTextImageButton: UIButton {
    override func layoutSubviews() {
        super.layoutSubviews()
        self.semanticContentAttribute = .forceRightToLeft
        self.contentHorizontalAlignment = .left

        guard let imageView = imageView,
              let title = title(for: .normal),
              let font = titleLabel?.font else { return }
       
        imageEdgeInsets = UIEdgeInsets(top: 0, left: bounds.width - imageView.bounds.width - title.textSizeWithFont(font).width, bottom: 0, right: 0)
        titleEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
    }
}

extension String {
    func textSizeWithFont(_ font: UIFont) -> CGSize {
        return self.size(withAttributes: [.font: font])
    }
}

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

<input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.

(throws IOException)

Image image = null;
try {
    URL url = new URL("http://www.yahoo.com/image_to_read.jpg");
    image = ImageIO.read(url);
} catch (IOException e) {
}

See javax.imageio package for more info. That's using the AWT image. Otherwise you could do:

 URL url = new URL("http://www.yahoo.com/image_to_read.jpg");
InputStream in = new BufferedInputStream(url.openStream());
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buf = new byte[1024];
int n = 0;
while (-1!=(n=in.read(buf)))
{
   out.write(buf, 0, n);
}
out.close();
in.close();
byte[] response = out.toByteArray();

And you may then want to save the image so do:

FileOutputStream fos = new FileOutputStream("C://borrowed_image.jpg");
fos.write(response);
fos.close();

thanks to everyone else for the clues.

I used this method

div.image-thumbnail
{
    width: 85px;
    height: 85px;
    line-height: 85px;
    display: inline-block;
    text-align: center;
}
div.image-thumbnail img
{
    vertical-align: middle;
}

Very late to the party, but posting in case this may help someone in the future. For my use case, the following function worked the best. Works to pull any data type out of dictionary

dict is the dictionary containing our value

list is a list of "steps" towards our value

def getnestedvalue(dict, list):

    length = len(list)
    try:
        for depth, key in enumerate(list):
            if depth == length - 1:
                output = dict[key]
                return output
            dict = dict[key]
    except (KeyError, TypeError):
        return None

    return None

I got tired of seeing this page with its by-now stale references to defunct Codehaus pages so I asked on the Maven Users mailing list and got some more up-to-date answers.

I would say that the best (and most authoritative) answer contained in my link above is the one contributed by Hervé BOUTEMY:

here is the core reference: http://maven.apache.org/ref/3-LATEST/maven-model-builder/

it does not explain everyting that can be found in POM or in settings, since there are so much info available but it points to POM and settings descriptors and explains everything that is not POM or settings

There is no difference in terms of functionality

The addwithvalue method takes an object as the value. There is no type data type checking. Potentially, that could lead to error if data type does not match with SQL table. The add method requires that you specify the Database type first. This helps to reduce such errors.

The above answer is already satisfying the topic. Anyway, if you need all the data in memory - have a look at bcolz. Its compressing the data in memory. I have had really good experience with it. But its missing a lot of pandas features

Edit: I got compression rates at around 1/10 or orig size i think, of course depending of the kind of data. Important features missing were aggregates.

For me android:gravity="center" did the trick in the parent layout element.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/fullImageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:contentDescription="@string/fullImageView"
        android:layout_gravity="center" />

</LinearLayout>

I think that the best way i use git rebase -i. I created a video to show the steps to split a commit: https://www.youtube.com/watch?v=3EzOz7e1ADI

The String class exposes some methods to enable this, such as IndexOf and LastIndexOf, so that you may do this:

Dim myText = "abcde"
Dim dIndex = myText.IndexOf("d")
If (dIndex > -1) Then

End If

$(function() {
  $('.mhz-news-img img').each(function() {
    var maxWidth = 320; // Max width for the image
    var maxHeight = 200;    // Max height for the image
    var maxratio=maxHeight/maxWidth;
    var width = $(this).width();    // Current image width
    var height = $(this).height();  // Current image height
    var curentratio=height/width;
    // Check if the current width is larger than the max

    if(curentratio>maxratio)
    {
        ratio = maxWidth / width;   // get ratio for scaling image
        $(this).css("width", maxWidth); // Set new width
        $(this).css("height", height *ratio); // Scale height based on ratio
    }
    else
    { 
        ratio = maxHeight / height; // get ratio for scaling image
        $(this).css("height", maxHeight);   // Set new height
        $(this).css("width", width * ratio);    // Scale width based on ratio

For people who are not able to find the coverage view , follow these steps :

Go to Windows Menu bar > Show View > Other > Type coverage and open it.

Click on Coverage.

To clear highlightings, click on X or XX icon as per convenience.

One-liner.

i.fa.fa-chevron-right.collapse.in { transform: rotate(180deg); }

In this example it's being used to group collapsible table rows. The only thing you need to do is add the target class name (my-collapse-name) to your icon:

<tr data-toggle="collapse" data-target=".my-collapse-name">
    <th><i class="fa fa-chevron-right my-collapse-name"></span></th>
    <th>Master Row - Title</th>
</tr>
<tr class="collapse my-collapse-name">
    <td></td>
    <td>Detail Row - Content</td>
</tr>

You could accomplish the same with Bootstrap's native caret class by using <span class='caret my-collapse-name'></span> and span.caret.collapse.in { transform: rotate(90deg); }

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

Its very easy to create procedure in Mysql. Here, in my example I am going to create a procedure which is responsible to fetch all data from student table according to supplied name.

DELIMITER //
CREATE PROCEDURE getStudentInfo(IN s_name VARCHAR(64))
BEGIN
SELECT * FROM student_database.student s where s.sname = s_name;
END//
DELIMITER;

In the above example ,database and table names are student_database and student respectively. Note: Instead of s_name, you can also pass @s_name as global variable.

How to call procedure? Well! its very easy, simply you can call procedure by hitting this command

$mysql> CAll getStudentInfo('pass_required_name');

You can go to Design mode and select "Fix" at the bottom of the warning. Then a pop up will appear (seems like it's going to register the new string) and voila, the error is fixed.

This will solve the problem:

const json_data = {"2013-01-21":1,"2013-01-22":7};

const arr = Object.keys(json_data).map((key) => [key, json_data[key]]);

console.log(arr);

Or using Object.entries() method:

console.log(Object.entries(json_data));

In both the cases, output will be:

/* output: 
[['2013-01-21', 1], ['2013-01-22', 7]]
*/

Look at the documentation regarding the SELECT ... INTO OUTFILE syntax.

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

Possible repeated question from How to overcome the CORS issue in ReactJS

CORS works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. This must be configured in the server to allow cross domain.

You can temporary solve this issue by a chrome plugin called CORS.

This worked for me:

$(window).scroll(function() {
  buffer = 40 // # of pixels from bottom of scroll to fire your function. Can be 0
  if ($(".myDiv").prop('scrollHeight') - $(".myDiv").scrollTop() <= $(".myDiv").height() + buffer )   {
    doThing();
  }
});

Must use jQuery 1.6 or higher

Since people will be coming from Google, make sure you're in the right database.

Running SQL in the 'master' database will often return this error.

I have had the exact same problem with a solution, that System.Windows.Interactivity was required for one of the project in Visual Studio 2019, and I tried to install Blend for Visual Studio SDK for .NET from Visual Studio 2019 Individual components, but it did not exist in it.

The consequence of that, I was not able to build the project in my solution with repetitive of following similar error on different XAML parts of the project:

The tag 'Interaction.Behaviors' does not exist in XML namespace 'clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity'.

The above mentioned errors snapshot example

The solution, the way I solved it, is by installing Microsoft Expression Blend Software Development Kit (SDK) for .NET 4 from Microsoft.

Thanks to my colleague @felza, mentioned that System.Windows.Interactivity requires this sdk, that is suppose to be located in this folder:

C:\Program Files (x86)\Microsoft SDKs\Expression\Blend\.NETFramework\v4.0

In my case it was not installed. I have had this folder C:\Program Files (x86)\Microsoft SDKs with out Expression\Blend\.NETFramework\v4.0 folder inside it.

After installing it, all errors disappeared.

This is shorter, but shorter isn't necessarily better (and it won't catch integer values which are out of range, as pointed out in danatel's comment):

input.matches("^-?\\d+$");

Personally, since the implementation is squirrelled away in a helper method and correctness trumps length, I would just go with something like what you have (minus catching the base Exception class rather than NumberFormatException).

With the background-size property in those browsers which support this very new feature of CSS.

Does this work for you?

string1.indexOf(string2) >= 0

Edit: This may not be faster than a RegExp if the string2 contains repeated patterns. On some browsers, indexOf may be much slower than RegExp. See comments.

Edit 2: RegExp may be faster than indexOf when the strings are very long and/or contain repeated patterns. See comments and @Felix's answer.

Take a look on a free tool - Valentina Studio. Amazing product! IMO this is the best manager for SQLite for all platforms:

Just to answer this question in a little more detail, and as Pavel said, Batch Normalization is just another layer, so you can use it as such to create your desired network architecture.

The general use case is to use BN between the linear and non-linear layers in your network, because it normalizes the input to your activation function, so that you're centered in the linear section of the activation function (such as Sigmoid). There's a small discussion of it here

In your case above, this might look like:

# import BatchNormalization
from keras.layers.normalization import BatchNormalization

# instantiate model
model = Sequential()

# we can think of this chunk as the input layer
model.add(Dense(64, input_dim=14, init='uniform'))
model.add(BatchNormalization())
model.add(Activation('tanh'))
model.add(Dropout(0.5))

# we can think of this chunk as the hidden layer    
model.add(Dense(64, init='uniform'))
model.add(BatchNormalization())
model.add(Activation('tanh'))
model.add(Dropout(0.5))

# we can think of this chunk as the output layer
model.add(Dense(2, init='uniform'))
model.add(BatchNormalization())
model.add(Activation('softmax'))

# setting up the optimization of our weights 
sgd = SGD(lr=0.1, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='binary_crossentropy', optimizer=sgd)

# running the fitting
model.fit(X_train, y_train, nb_epoch=20, batch_size=16, show_accuracy=True, validation_split=0.2, verbose = 2)

Hope this clarifies things a bit more.

All upper code is not correct to the end.

This is because when searching zz*foo* or zz* you will not get correct results.

And if you search "abcd*" in "abcd" in TotalCommander will he find a abcd file so all upper code is wrong.

Here is the correct code.

public string WildcardToRegex(string pattern)
{             
    string result= Regex.Escape(pattern).
        Replace(@"\*", ".+?").
        Replace(@"\?", "."); 

    if (result.EndsWith(".+?"))
    {
        result = result.Remove(result.Length - 3, 3);
        result += ".*";
    }

    return result;
}

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

XAMPP should have come with a "fake" sendmail program. In that case, you can use sendmail as well:

[mail function]
; For Win32 only.
; http://php.net/smtp
;SMTP = localhost
; http://php.net/smtp-port
;smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = [email protected]

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -i"

Sendmail should have a sendmail.ini with it; it should be configured as so:

# Example for a user configuration file

# Set default values for all following accounts.
defaults
logfile "C:\xampp\sendmail\sendmail.log"

# Mercury
#account Mercury
#host localhost
#from postmaster@localhost
#auth off

# A freemail service example
account ACCOUNTNAME_HERE
tls on
tls_certcheck off
host smtp.gmail.com
from EMAIL_HERE
auth on
user EMAIL_HERE
password PASSWORD_HERE

# Set a default account
account default : ACCOUNTNAME_HERE

Of course, replace ACCOUNTNAME_HERE with an arbitrary account name, replace EMAIL_HERE with a valid email (such as a Gmail or Hotmail), and replace PASSWORD_HERE with the password to your email. Now, you should be able to send mail. Remember to restart Apache (from the control panel or the batch files) to allow the changes to PHP to work.

I would use git stash save --patch. I don't find the interactivity to be annoying because there are options during it to apply the desired operation to entire files.

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

The accepted answer is helpful, but it isn't immediately obvious how to retrieve a filename from a path if you are NOT using passed in values. I was able to work this out from this thread, but in case others aren't so lucky, here is how it is done:

@echo off
setlocal enabledelayedexpansion enableextensions

set myPath=C:\Somewhere\Somewhere\SomeFile.txt
call :file_name_from_path result !myPath!
echo %result%
goto :eof

:file_name_from_path <resultVar> <pathVar>
(
    set "%~1=%~nx2"
    exit /b
)

:eof
endlocal

Now the :file_name_from_path function can be used anywhere to retrieve the value, not just for passed in arguments. This can be extremely helpful if the arguments can be passed into the file in an indeterminate order or the path isn't passed into the file at all.

For formatting jsonfile gives spaces option which you can pass as a parameter:

   jsonfile.writeFile(file, obj, {spaces: 2}, function (err) {
         console.error(err);
   })

Or use jsonfile.spaces = 4. Read details here.

I would not suggest writing to file each time in the loop, instead construct the JSON object in the loop and write to file outside the loop.

var jsonfile = require('jsonfile');
var obj={
     'table':[]
    };

for (i=0; i <11 ; i++){
       obj.table.push({"id":i,"square":i*i});
}
jsonfile.writeFile('loop.json', obj, {spaces:2}, function(err){
      console.log(err);
});

Use cd in a subshell; the shorthand way to use this kind of subshell is parentheses.

(cd wherever; mycommand ...)

That said, if your command has an environment that it requires, it should really ensure that environment itself instead of putting the onus on anything that might want to use it (unless it's an internal command used in very specific circumstances in the context of a well defined larger system, such that any caller already needs to ensure the environment it requires). Usually this would be some kind of shell script wrapper.

Java 8 - LocalDateTime

What about this?

final LocalDateTime now = LocalDateTime.now();
final LocalDateTime minRange = LocalDateTime.of(now.getYear(), now.getMonth(), now.getDayOfMonth(), 22, 30); //Today, 10:30pm
LocalDateTime maxRange = LocalDateTime.of(now.getYear(), now.getMonth(), now.getDayOfMonth(), 6, 30); //Tomorrow, 6:30am
maxRange = maxRange.plusDays(1); //Ensures that you don't run into an exception if minRange is the last day in the month.
if (now.isAfter(minRange) && now.isBefore(maxRange)) {
    //Action
}

The best way I have found is to use jQuery JSON

.row {
    margin-right: 15px;
}

throw this in your CSS

Use the @import method:

@import url('https://fonts.googleapis.com/css?family=Open+Sans&display=swap');

Obviously, "Open Sans" (Open+Sans) is the font that is imported. So replace it with yours. If the font's name has multiple words, URL-encode it by adding a + sign between each word, as I did.

Make sure to place the @import at the very top of your CSS, before any rules.

Google Fonts can automatically generate the @import directive for you. Once you have chosen a font, click the (+) icon next to it. In bottom-left corner, a container titled "1 Family Selected" will appear. Click it, and it will expand. Use the "Customize" tab to select options, and then switch back to "Embed" and click "@import" under "Embed Font". Copy the CSS between the <style> tags into your stylesheet.

                            }
                            else
                            {
                                Console.WriteLine(task1.Result);
                            }
                        });
                    }
                }

            }).Wait();

            Console.Read();
            connection.Stop();
        }
    }
}

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

Yes you can use .is(':visible') in jquery. But while the code is running under the safari browser .is(':visible') is won't work.

So please use the below code

if( $(".example").offset().top > 0 )

The above line will work both IE as well as safari also.

You need to download this from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=7435.

The tool is called "Microsoft URL Rewrite Module 2.0 for IIS 7" and is described as follows by Microsoft: "URL Rewrite Module 2.0 provides a rule-based rewriting mechanism for changing requested URL’s before they get processed by web server and for modifying response content before it gets served to HTTP clients"

I think this example explains clearly the differences between inheritance and composition.

In this exmple, the problem is solved using inheritance and composition. The author pays attention to the fact that ; in inheritance, a change in superclass might cause problems in derived class, that inherit it.

There you can also see the difference in representation when you use a UML for inheritance or composition.

You can not use input for it, you need to use textarea instead. Use textarea with the wrap="soft"code and optional the rest of the attributes like this:

<textarea name="text" rows="14" cols="10" wrap="soft"> </textarea>

Atributes: To limit the amount of text in it for example to "40" characters you can add the attribute maxlength="40" like this: <textarea name="text" rows="14" cols="10" wrap="soft" maxlength="40"></textarea> To hide the scroll the style for it. if you only use overflow:scroll; or overflow:hidden; or overflow:auto; it will only take affect for one scroll bar. If you want different attributes for each scroll bar then use the attributes like this overflow:scroll; overflow-x:auto; overflow-y:hidden; in the style area: To make the textarea not resizable you can use the style with resize:none; like this:

<textarea name="text" rows="14" cols="10" wrap="soft" maxlength="40" style="overflow:hidden; resize:none;></textarea>

That way you can have or example a textarea with 14 rows and 10 cols with word wrap and max character length of "40" characters that works exactly like a input text box does but with rows instead and without using input text.

NOTE: textarea works with rows unlike like input <input type="text" name="tbox" size="10"></input> that is made to not work with rows at all.

You should have a look at the official ICU4J library. It provides a MessageFormat class similar to the one available with the JDK but this former supports named placeholders.

Unlike other solutions provided on this page. ICU4j is part of the ICU project that is maintained by IBM and regularly updated. In addition, it supports advanced use cases such as pluralization and much more.

Here is a code example:

MessageFormat messageFormat =
        new MessageFormat("Publication written by {author}.");

Map<String, String> args = Map.of("author", "John Doe");

System.out.println(messageFormat.format(args));

We encountered a very similar situation.

Activity 1 (Opening) -> Activity 2 (Preview) -> Activity 3 (Detail)

Incorrect "on back press" Response

• Device back press on Activity 3 will also close Activity 2.

I have checked all answers posted above and none of them worked. Java syntax for transition between Activity 2 and Activity 3 was reviewed to be correct.

Fresh from coding on calling out a 3rd party app. by an Activity. We decided to investigate the configuration angle - eventually enabling us to identify the root cause of the problem.

Scope: Configuration of Activity 2 (caller).

Root Cause:

android:launchMode="singleInstance"

Solution:

android:launchMode="singleTask"

Apparently on this "on back press" issue singleInstance considers invoked Activities in one instance with the calling Activity, whereas singleTask will allow for invoked Activities having their own identity enough for the intended on back press to function to work as it should to.

I've found a secure and reliable way in my InnoSetup-based script to understand whether a particular application is 32-bit or 64-bit (in my case I needed to test Excel), by using a Win32 API function. This function is called GetBinaryType(), it comes from `kernel32' (despite the name it comes in 32 and 64 bit flavor) and looks directly at the exe's header.

You can use mutate_if (dplyr):

For example, coerce integer in factor:

mydata=structure(list(a = 1:10, b = 1:10, c = c("a", "a", "b", "b", 
"c", "c", "c", "c", "c", "c")), row.names = c(NA, -10L), class = c("tbl_df", 
"tbl", "data.frame"))

# A tibble: 10 x 3
       a     b c    
   <int> <int> <chr>
 1     1     1 a    
 2     2     2 a    
 3     3     3 b    
 4     4     4 b    
 5     5     5 c    
 6     6     6 c    
 7     7     7 c    
 8     8     8 c    
 9     9     9 c    
10    10    10 c   

Use the function:

library(dplyr)

mydata%>%
    mutate_if(is.integer,as.factor)

# A tibble: 10 x 3
       a     b c    
   <fct> <fct> <chr>
 1     1     1 a    
 2     2     2 a    
 3     3     3 b    
 4     4     4 b    
 5     5     5 c    
 6     6     6 c    
 7     7     7 c    
 8     8     8 c    
 9     9     9 c    
10    10    10 c    

Thanks for Sharing. After struggling for 1.5 days, noticed that Report Server was configured with wrong domain IP. It was configured with backup domain IP which is offline. I have identified this in the user group configuration where Domain name was not listed. Changed IP and reboot the Report server. Issue resolved.

Whevever you get a problem like this just go to the man page for the function in question and it will tell you what header you are missing, e.g.

$ man memset

MEMSET(3)                BSD Library Functions Manual                MEMSET(3)

NAME
     memset -- fill a byte string with a byte value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memset(void *b, int c, size_t len);

Note that for C++ it's generally preferable to use the proper equivalent C++ headers, <cstring>/<cstdio>/<cstdlib>/etc, rather than C's <string.h>/<stdio.h>/<stdlib.h>/etc.

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

Wrapping works but when you just want a space, I like:

<div class="col-xs-12" style="height:50px;"></div>

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

It works for me.

parseInt() -> Parses a number to specified redix.

Number()-> Converts the specified value to its numeric equivalent or NaN if it fails to do so.

Hence for converting some non-numeric value to number we should always use Number() function.

eg.

Number("")//0
parseInt("")//NaN

Number("123")//123
parseInt("123")//123

Number("123ac") //NaN,as it is a non numeric string
parsInt("123ac") //123,it parse decimal number outof string

Number(true)//1
parseInt(true) //NaN

There are various corner case to parseInt() functions as it does redix conversion, hence we should avoid using parseInt() function for coersion purposes.

Now, to check weather the provided value is Numeric or not,we should use nativeisNaN() function

Date.prototype.dayOfYear= function(){
    var j1= new Date(this);
    j1.setMonth(0, 0);
    return Math.round((this-j1)/8.64e7);
}

alert(new Date().dayOfYear())

The problem with catching the click event is that each subsequent click within the text will select it again, whereas the user was probably expecting to reposition the cursor.

What worked for me was declaring a variable, selectSearchTextOnClick, and setting it to true by default. The click handler checks that the variable's still true: if it is, it sets it to false and performs the select(). I then have a blur event handler which sets it back to true.

Results so far seem like the behavior I'd expect.

(Edit: I neglected to say that I'd tried catching the focus event as someone suggested,but that doesn't work: after the focus event fires, the click event can fire, immediately deselecting the text).

Here's a nice, tidy solution for you: (also see the live demo ->)

window.onload = function start() {
    slide();
}

function slide() {
    var currMarg = 0,
        contStyle = document.getElementById('container').style;
    setInterval(function() {
        currMarg = currMarg == 1800 ? 0 : currMarg + 600;
        contStyle.marginLeft = '-' + currMarg + 'px';
    }, 3000);
}

Since you are trying to learn, allow me to explain how this works.

First we declare two variables: currMarg and contStyle. currMarg is an integer that we will use to track/update what left margin the container should have. We declare it outside the actual update function (in a closure), so that it can be continuously updated/access without losing its value. contStyle is simply a convenience variable that gives us access to the containers styles without having to locate the element on each interval.

Next, we will use setInterval to establish a function which should be called every 3 seconds, until we tell it to stop (there's your infinite loop, without freezing the browser). It works exactly like setTimeout, except it happens infinitely until cancelled, instead of just happening once.

We pass an anonymous function to setInterval, which will do our work for us. The first line is:

currMarg = currMarg == 1800 ? 0 : currMarg + 600;

This is a ternary operator. It will assign currMarg the value of 0 if currMarg is equal to 1800, otherwise it will increment currMarg by 600.

With the second line, we simply assign our chosen value to containers marginLeft, and we're done!

Note: For the demo, I changed the negative values to positive, so the effect would be visible.

Short answer

The purpose of meshgrid is to help remplace Python loops (slow interpreted code) by vectorized operations within C NumPy library.

Borrowed from this site.

x = np.arange(-4, 4, 0.25)
y = np.arange(-4, 4, 0.25)
X, Y = np.meshgrid(x, y)
R = np.sqrt(X**2 + Y**2)
Z = np.sin(R)

meshgrid is used to create pairs of coordinates between -4 and +4 with .25 increments in each direction X and Y. Each pair is then used to find R, and Z from it. This way of preparing "a grid" of coordinates is frequently used in plotting 3D surfaces, or coloring 2D surfaces.

Details: Python for-loop vs NumPy vector operation

To take a more simple example, let's say we have two sequences of values,

a = [2,7,9,20]    
b = [1,6,7,9]    ?

and we want to perform an operation on each possible pair of values, one taken from the first list, one taken from the second list. We also want to store the result. For example, let's say we want to get the sum of the values for each possible pair.

Slow and laborious method

c = []    
for i in range(len(b)):    
    row = []    
    for j in range(len(a)):    
        row.append (a[j] + b[i])
    c.append (row)    
print (c)

Result:

[[3, 8, 10, 21],
 [8, 13, 15, 26],
 [9, 14, 16, 27],
 [11, 16, 18, 29]]

Python is interpreted, these loops are relatively slow to execute.

Fast and easy method

meshgrid is intended to remove the loops from the code. It returns two arrays (i and j below) which can be combined to scan all the existing pairs like this:

i,j = np.meshgrid (a,b)    
c = i + j    
print (c)

Result:

[[ 3  8 10 21]
 [ 8 13 15 26]
 [ 9 14 16 27]
 [11 16 18 29]]

Meshgrid under the hood

The two arrays prepared by meshgrid are:

(array([[ 2,  7,  9, 20],
        [ 2,  7,  9, 20],
        [ 2,  7,  9, 20],
        [ 2,  7,  9, 20]]),

 array([[1, 1, 1, 1],
        [6, 6, 6, 6],
        [7, 7, 7, 7],
        [9, 9, 9, 9]]))

These arrays are created by repeating the values provided. One contains the values in identical rows, the other contains the other values in identical columns. The number of rows and column is determined by the number of elements in the other sequence.

The two arrays created by meshgrid are therefore shape compatible for a vector operation. Imagine x and y sequences in the code at the top of page having a different number of elements, X and Y resulting arrays will be shape compatible anyway, not requiring any broadcast.

Origin

numpy.meshgrid comes from MATLAB, like many other NumPy functions. So you can also study the examples from MATLAB to see meshgrid in use, the code for the 3D plotting looks the same in MATLAB.

Use my_map.count( key ); it can only return 0 or 1, which is essentially the Boolean result you want.

Alternately my_map.find( key ) != my_map.end() works too.

You should flatten using this code ( taken from http://kogs-www.informatik.uni-hamburg.de/~meine/python_tricks ), the code is untested, but I'm pretty sure it works:

def flatten(x):
    """flatten(sequence) -> list

    Returns a single, flat list which contains all elements retrieved
    from the sequence and all recursively contained sub-sequences
    (iterables).

    Examples:
    >>> [1, 2, [3,4], (5,6)]
    [1, 2, [3, 4], (5, 6)]
    >>> flatten([[[1,2,3], (42,None)], [4,5], [6], 7, MyVector(8,9,10)])
    [1, 2, 3, 42, None, 4, 5, 6, 7, 8, 9, 10]"""

    result = []
    for el in x:
        #if isinstance(el, (list, tuple)):
        if hasattr(el, "__iter__") and not isinstance(el, basestring):
            result.extend(flatten(el))
        else:
            result.append(el)
    return result

After you had flattened the list, you perform the intersection in the usual way:

c1 = [1, 6, 7, 10, 13, 28, 32, 41, 58, 63]
c2 = [[13, 17, 18, 21, 32], [7, 11, 13, 14, 28], [1, 5, 6, 8, 15, 16]]

def intersect(a, b):
     return list(set(a) & set(b))

print intersect(flatten(c1), flatten(c2))

I tried a bunch of the answers here, even the "best" answer. They all came up short of what I specifically was after. So besides the past 12 hours of sitting in regex code for multiple programs and reading and testing these answers this is what I came up with which works EXACTLY like I want.

 find . -type f -name "*.*" | grep -o -E "\.[^\.]+$" | grep -o -E "[[:alpha:]]{2,16}" | awk '{print tolower($0)}' | sort -u

• Finds all files which may have an extension.
• Greps only the extension
• Greps for file extensions between 2 and 16 characters (just adjust the numbers if they don't fit your need). This helps avoid cache files and system files (system file bit is to search jail).
• Awk to print the extensions in lower case.
• Sort and bring in only unique values. Originally I had attempted to try the awk answer but it would double print items that varied in case sensitivity.

If you need a count of the file extensions then use the below code

find . -type f -name "*.*" | grep -o -E "\.[^\.]+$" | grep -o -E "[[:alpha:]]{2,16}" | awk '{print tolower($0)}' | sort | uniq -c | sort -rn

While these methods will take some time to complete and probably aren't the best ways to go about the problem, they work.

Update: Per @alpha_989 long file extensions will cause an issue. That's due to the original regex "[[:alpha:]]{3,6}". I have updated the answer to include the regex "[[:alpha:]]{2,16}". However anyone using this code should be aware that those numbers are the min and max of how long the extension is allowed for the final output. Anything outside that range will be split into multiple lines in the output.

Note: Original post did read "- Greps for file extensions between 3 and 6 characters (just adjust the numbers if they don't fit your need). This helps avoid cache files and system files (system file bit is to search jail)."

Idea: Could be used to find file extensions over a specific length via:

 find . -type f -name "*.*" | grep -o -E "\.[^\.]+$" | grep -o -E "[[:alpha:]]{4,}" | awk '{print tolower($0)}' | sort -u

Where 4 is the file extensions length to include and then find also any extensions beyond that length.

Tilde folders

In the event pip uninstall numpy and reinstallation of Numpy does not work. Review your site-packages folder for sub-folders beginning with a tilde ~

These folders relate to pip installations that got mangled and the installation was aborted part way through. The tilde folders were only ever meant to be tmp folders but ended up becoming permanent. In my case there was a file called ~mpy which was a mangled legacy Numpy folder. This led to compatibility issues and ImportErrors.

These mangled folders can safely be deleted, for further details see this answer

Go has objects. Objects can have constructors (although not automatic constructors). And finally, Go is an OOP language (data types have methods attached, but admittedly there are endless definitions of what OOP is.)

Nevertheless, the accepted best practice is to write zero or more constructors for your types.

As @dystroy posted his answer before me finishing this answer, let me just add an alternative version of his example constructor, which I would probably write instead as:

func NewThing(someParameter string) *Thing {
    return &Thing{someParameter, 33} // <- 33: a very sensible default value
}

The reason I want to show you this version is that pretty often "inline" literals can be used instead of a "constructor" call.

a := NewThing("foo")
b := &Thing{"foo", 33}

Now *a == *b.

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

Use this:

SELECT s.name AS Student, c.name AS Course 
FROM student s 
  LEFT JOIN (bridge b CROSS JOIN course c) 
    ON (s.id = b.sid AND b.cid = c.id);

In order to access project from the homepage you need to create a Virtual Host first.

Most easiest way to do this is to use Wamp's Add a Virtual Host Utility.

Just follow these steps:

1. Create a folder inside "C:\wamp\www\" directory and give it a name that you want to give to your site for eg. 'mysite'. So the path would be "C:\wamp\www\mysite".
2. Now open localhost's homepage in your browser, under Tools menu click on Add a Virtual Host link.
3. Enter the name of the virtual host, that name must be the name of the folder we created inside www directory i.e. 'mysite'.
4. Enter absolute path of the virtual host i.e. "C:\wamp\www\mysite\" without quotes and click the button below saying 'Start the creation of the VirtualHost'.
5. Virtual Host created, now you just need to 'Restart DNS'. To do this right click the wamp server's tray menu icon, click on Tools > Restart DNS and let the tray menu icon become green again.
6. All set! Now just create 'index.php' page inside "C:\wamp\www\mysite\" directory. Add some code in 'index.php' file, like
   <?php echo "<h1>Hello World</h1>"; ?>

Now you can access the projects from the localhost's homepage. Just click the project link and you'll see 'Hello World' printed on your screen.

I have successfully used as shown below in Jenkinsfile:

steps {
  script {
    def reportPath = "${WORKSPACE}/target/report"
    ...
  }
}

Try linux command chsh.

The detailed command is chsh -s /bin/bash. It will prompt you to enter your password. Your default login shell is /bin/bash now. You must log out and log back in to see this change.

The following is quoted from man page:

The chsh command changes the user login shell. This determines the name of the users initial login command. A normal user may only change the login shell for her own account, the superuser may change the login shell for any account

This command will change the default login shell permanently.

Note: If your user account is remote such as on Kerberos authentication (e.g. Enterprise RHEL) then you will not be able to use chsh.

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

The steel is far from hot, but I combined @abatishchev's solution with the answer from this post and got to this result. Hope it's useful:

public static class GlobalVars
{
    private const string GlobalKey = "AllMyVars";

    static GlobalVars()
    {
        Hashtable table = HttpContext.Current.Application[GlobalKey] as Hashtable;

        if (table == null)
        {
            table = new Hashtable();
            HttpContext.Current.Application[GlobalKey] = table;
        }
    }

    }

                Vars.Remove(varName);
            }
            return;
        }

        if (Vars[varName] == null)
        {
            Vars.Add(varName, value);

        }
    }
}

If you're testing this out in postman / insomnia and are just trying to get it working, hint: the server auth code (code parameter) is only good once. Meaning if you stuff up any of the other parameters in the request and get back a 400, you'll need to use a new server auth code or you'll just get another 400.

use this, it realy works:

data.addColumn no of your key, you can add more columns or remove

<?php
$con=mysql_connect("localhost","USername","Password") or die("Failed to connect with database!!!!");
mysql_select_db("Database Name", $con); 
// The Chart table contain two fields: Weekly_task and percentage
//this example will display a pie chart.if u need other charts such as Bar chart, u will need to change little bit to make work with bar chart and others charts
$sth = mysql_query("SELECT * FROM chart");

while($r = mysql_fetch_assoc($sth)) {
$arr2=array_keys($r);
$arr1=array_values($r);

}

for($i=0;$i<count($arr1);$i++)
{
    $chart_array[$i]=array((string)$arr2[$i],intval($arr1[$i]));
}
echo "<pre>";

So I had this exact same issue and lost about 6 hours of my life searching, I had the

withCredentials: true

But the browser still didn't save the cookie until for some weird reason I had the idea to shuffle the configuration setting:

Axios.post(GlobalVariables.API_URL + 'api/login', {
        email,
        password,
        honeyPot
    }, {
        withCredentials: true,
        headers: {'Access-Control-Allow-Origin': '*', 'Content-Type': 'application/json'
    }});

Seems like you should always send the 'withCredentials' Key first.

Here is an even simpler solution using base graphics and alpha-blending (which does not work on all graphics devices):

set.seed(42)
p1 <- hist(rnorm(500,4))                     # centered at 4
p2 <- hist(rnorm(500,6))                     # centered at 6
plot( p1, col=rgb(0,0,1,1/4), xlim=c(0,10))  # first histogram
plot( p2, col=rgb(1,0,0,1/4), xlim=c(0,10), add=T)  # second

The key is that the colours are semi-transparent.

Edit, more than two years later: As this just got an upvote, I figure I may as well add a visual of what the code produces as alpha-blending is so darn useful:

Unfortunately, this answer here by @EatOng is not correct. After reading his answer I added a dummy variable to every AJAX request I was firing (even if some of them already had some fields) just to be sure the error never appears.

But just now I came across the same damn error from PHP. I double-confirmed that I had sent some POST data (some other fields too along with the dummy variable). PHP version 5.6.25, always_populate_raw_post_data value is set to 0.

Also, as I am sending a application/json request, PHP is not populating it to $_POST, rather I have to json_decode() the raw POST request body, accessible by php://input.

As the answer by @rr- cites,

0/off/whatever: BC behavior (populate if content-type is not registered or request method is other than POST).

Because the request method is for sure POST, I guess PHP didn't recognize/like my Content-Type: application/json request (again, why??).

OPTION 1:

Edit the php.ini file manually and set the culprit variable to -1, as many of the answers here suggest.

OPTION 2:

This is a PHP 5.6 bug. Upgrade PHP.

OPTION 3:

As @user9541305 answered here, changing the Content-Type of AJAX request to application/x-www-form-urlencoded or multipart/form-data will make PHP populate the $_POST from the POSTed body (because PHP likes/recognizes those content-type headers!?).

OPTION 4: LAST RESORT

Well, I did not want to change the Content-Type of AJAX, it would cause a lot of trouble for debugging. (Chrome DevTools nicely views the POSTed variables of JSON requests.)

I am developing this thing for a client and cannot ask them to use latest PHP, nor to edit the php.ini file. As a last resort, I will just check if it is set to 0 and if so, edit the php.ini file in my PHP script itself. Of course I will have to ask the user to restart apache. What a shame!

Here is a sample code:

<?php

if(ini_get('always_populate_raw_post_data') != '-1')
{
    // Get the path to php.ini file
    $iniFilePath = php_ini_loaded_file();

    // Get the php.ini file content
    $iniContent = file_get_contents($iniFilePath);

    // Un-comment (if commented) always_populate_raw_post_data line, and set its value to -1
    $iniContent = preg_replace('~^\s*;?\s*always_populate_raw_post_data\s*=\s*.*$~im', 'always_populate_raw_post_data = -1', $iniContent);

    // Write the content back to the php.ini file
    file_put_contents($iniFilePath, $iniContent);

    // Exit the php script here
    // Also, write some response here to notify the user and ask to restart Apache / WAMP / Whatever.
    exit;
}

 MVC Cascading Dropdown List Using Jquery</h4>

On MVC 5 is quite similar

@Html.ActionLink("LinkText", "ActionName", new { id = "id" })

You can pass a method as parameter with method(:function) way. Below is a very simple example:

def double(a)
  return a * 2 
end
=> nil

def method_with_function_as_param( callback, number) 
  callback.call(number) 
end 
=> nil

method_with_function_as_param( method(:double) , 10 ) 
=> 20

Well, as the error says, you have an expression (((t[1])/length) * t[1]) on the left side of the assignment, rather than a variable name. You have that expression, and then you tell Python to add string to it (which is always "") and assign it to... where? ((t[1])/length) * t[1] isn't a variable name, so you can't store the result into it.

Did you mean string += ((t[1])/length) * t[1]? That would make more sense. Of course, you're still trying to add a number to a string, or multiply by a string... one of those t[1]s should probably be a t[0].

Comparison of execution time of bubble sort and selection sort I have a program which compares the execution time of bubble sort and selection sort. To find out the time of execution of a block of code compute the time before and after the block by

 clock_t start=clock();
 …
 clock_t end=clock();
 CLOCKS_PER_SEC is constant in time.h library

Example code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
   int a[10000],i,j,min,temp;
   for(i=0;i<10000;i++)
   {
      a[i]=rand()%10000;
   }
   //The bubble Sort
   clock_t start,end;
   start=clock();
   for(i=0;i<10000;i++)
   {
     for(j=i+1;j<10000;j++)
     {
       if(a[i]>a[j])
       {
         int temp=a[i];
         a[i]=a[j];
         a[j]=temp;
       }
     }
   }
   end=clock();
   double extime=(double) (end-start)/CLOCKS_PER_SEC;
   printf("\n\tExecution time for the bubble sort is %f seconds\n ",extime);

   for(i=0;i<10000;i++)
   {
     a[i]=rand()%10000;
   }
   clock_t start1,end1;
   start1=clock();
   // The Selection Sort
   for(i=0;i<10000;i++)
   {
     min=i;
     for(j=i+1;j<10000;j++)
     {
       if(a[min]>a[j])
       {
         min=j;
       }
     }
     temp=a[min];
     a[min]=a[i];
     a[i]=temp;
   }
   end1=clock();
   double extime1=(double) (end1-start1)/CLOCKS_PER_SEC;
   printf("\n");
   printf("\tExecution time for the selection sort is %f seconds\n\n", extime1);
   if(extime1<extime)
     printf("\tSelection sort is faster than Bubble sort by %f seconds\n\n", extime - extime1);
   else if(extime1>extime)
     printf("\tBubble sort is faster than Selection sort by %f seconds\n\n", extime1 - extime);
   else
     printf("\tBoth algorithms have the same execution time\n\n");
}

You can also try using multiprocessing.Process with daemon=True; the process.start() method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.

I experienced similar problem while working with falcon framework and using daemon process helped.

You'd need to do the following:

from multiprocessing import Process

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    heavy_process = Process(  # Create a daemonic process with heavy "my_func"
        target=my_func,
        daemon=True
    )
    heavy_process.start()
    return Response(
        mimetype='application/json',
        status=200
    )

# Define some heavy function
def my_func():
    time.sleep(10)
    print("Process finished")

You should get a response immediately and, after 10s you should see a printed message in the console.

NOTE: Keep in mind that daemonic processes are not allowed to spawn any child processes.

You could try using HTML5s sessionStorage it lasts for the duration on the page session. A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.

sessionStorage.setItem("username", "John");

The ByteBuffer class is important because it forms a basis for the use of channels in Java. ByteBuffer class defines six categories of operations upon byte buffers, as stated in the Java 7 documentation:

• Absolute and relative get and put methods that read and write single bytes;

• Relative bulk get methods that transfer contiguous sequences of bytes from this buffer into an array;

• Relative bulk put methods that transfer contiguous sequences of bytes from a byte array or some other byte buffer into this buffer;

• Absolute and relative get and put methods that read and write values of other primitive types, translating them to and from sequences of bytes in a particular byte order;

• Methods for creating view buffers, which allow a byte buffer to be viewed as a buffer containing values of some other primitive type; and

• Methods for compacting, duplicating, and slicing a byte buffer.

Example code : Putting Bytes into a buffer.

    // Create an empty ByteBuffer with a 10 byte capacity
    ByteBuffer bbuf = ByteBuffer.allocate(10);

    // Get the buffer's capacity
    int capacity = bbuf.capacity(); // 10

    // Use the absolute put(int, byte).
    // This method does not affect the position.
    bbuf.put(0, (byte)0xFF); // position=0

    // Set the position
    bbuf.position(5);

    // Use the relative put(byte)
    bbuf.put((byte)0xFF);

    // Get the new position
    int pos = bbuf.position(); // 6

    // Get remaining byte count
    int rem = bbuf.remaining(); // 4

    // Set the limit
    bbuf.limit(7); // remaining=1

    // This convenience method sets the position to 0
    bbuf.rewind(); // remaining=7

If path is not hardcoded in any script then your websites should work seamlessly.

Using these:

using System.Net;
using System.Net.Sockets;
using System.Net.NetworkInformation;
using System.Linq;

You can use a series of LINQ methods to grab the most preferred IP address.

public static bool IsIPv4(IPAddress ipa) => ipa.AddressFamily == AddressFamily.InterNetwork;

public static IPAddress GetMainIPv4() => NetworkInterface.GetAllNetworkInterfaces()
.Select((ni)=>ni.GetIPProperties())
.Where((ip)=> ip.GatewayAddresses.Where((ga) => IsIPv4(ga.Address)).Count() > 0)
.FirstOrDefault()?.UnicastAddresses?
.Where((ua) => IsIPv4(ua.Address))?.FirstOrDefault()?.Address;

This simply finds the first Network Interface that has an IPv4 Default Gateway, and gets the first IPv4 address on that interface. Networking stacks are designed to have only one Default Gateway, and therefore the one with a Default Gateway, is the best one.

WARNING: If you have an abnormal setup where the main adapter has more than one IPv4 Address, this will grab only the first one. (The solution to grabbing the best one in that scenario involves grabbing the Gateway IP, and checking to see which Unicast IP is in the same subnet as the Gateway IP Address, which would kill our ability to create a pretty LINQ method based solution, as well as being a LOT more code)

On Mac OS X El Capitan I had to run these two commands to fix this error:

xcode-select --install
pip install lxml

Which ended up installing lxml-3.5.0

When you run the xcode-select command you may have to sign a EULA (so have an X-Term handy for the UI if you're doing this on a headless machine).

    public Phone getMsg() {

That really depends on if you expect to find the object, or not. If you follow the school of thought that exceptions should be used for indicating something, well, err, exceptional has occured then:

• Object found; return object
• Object not-found; throw exception

Otherwise, return null.

Chromedriver is a WebDriver. WebDriver is an open-source tool for automated testing of web apps across many browsers. It provides capabilities for navigating to web pages, user input, JavaScript execution, and more. When you run this driver, it will enable your scripts to access this and run commands on Google Chrome.

This can be done via scripts running in the local network (Only local connections are allowed.) or via scripts running on outside networks (All remote connections are allowed.). It is always safer to use the Local Connection option. By default your Chromedriver is accessible via port 9515.

To answer the question, it is just an informational message. You don't have to worry about it.

Given below are both options.

When we are going to migrate JQuery from 1.x to 2x or 3.x in our old existing application , then we will use .done,.fail instead of success,error as JQuery up gradation is going to be deprecated these methods.For example when we make a call to server web methods then server returns promise objects to the calling methods(Ajax methods) and this promise objects contains .done,.fail..etc methods.Hence we will the same for success and failure response. Below is the example(it is for POST request same way we can construct for request type like GET...)

 $.ajax({
            type: "POST",
            url: url,
            data: '{"name" :"sheo"}',
            contentType: "application/json; charset=utf-8",
            async: false,
            cache: false
            }).done(function (Response) {
                  //do something when get response            })
           .fail(function (Response) {
                    //do something when any error occurs.
                });

string x ="Hi ,World";
string y = x;
char[] whitespace = new char[]{ ' ',\t'};          
string[] fooArray = y.Split(whitespace);  // now you have an array of 3 strings
y = String.Join(" ", fooArray);
string[] target = { "Hi", "World", "VW_Slep" };

for (int i = 0; i < target.Length; i++)
{
    string v = target[i];
    string results = Array.Find(fooArray, element => element.StartsWith(v, StringComparison.Ordinal));
    //
    if (results != null)
    { MessageBox.Show(results); }

The optional software packages are helpful to import your database SQL file faster

• with a progress view (pv)
• Parallel gzip (pigz/unpigz) to gzip/gunzip files in parallel

for faster zipping of the output

var model = {"Id": "xx", "Name":"Ravi"};
$.ajax({    url: 'test/set',
                        type: "POST",
                        data: model,
                        success: function (res) {
                            if (res != null) {
                                alert("done.");
                            }
                        },
                        error: function (res) {

                        }
                    });

You can use the directive v-html to show it. like this:

<td v-html="desc"></td>

As the error notes, the problem is in the line:

if guess[i] == winning_numbers[i]

The error is that your list indices are out of range--that is, you are trying to refer to some index that doesn't even exist. Without debugging your code fully, I would check the line where you are adding guesses based on input:

for i in range(tickets):
    bubble = input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split(" ")
    guess.append(bubble)
print(bubble)

The size of how many guesses you are giving your user is based on

# Prompts the user to enter the number of tickets they wish to play.
tickets = int(input("How many lottery tickets do you want?\n"))

So if the number of tickets they want is less than 5, then your code here

for i in range(5):

if guess[i] == winning_numbers[i]:
    match = match+1

return match

will throw an error because there simply aren't that many elements in the guess list.

You can also execute the following code. It is tested and working.

How about User-Defined Type Guards? https://www.typescriptlang.org/docs/handbook/advanced-types.html

interface Bird {
    fly();
    layEggs();
}

interface Fish {
    swim();
    layEggs();
}

function isFish(pet: Fish | Bird): pet is Fish { //magic happens here
    return (<Fish>pet).swim !== undefined;
}

// Both calls to 'swim' and 'fly' are now okay.

if (isFish(pet)) {
    pet.swim();
}
else {
    pet.fly();
}

Another option you can always consider is Apache Commons. It provides a lot of options.

import org.apache.commons.lang3.builder.CompareToBuilder;

Ex:

public int compare(Person a, Person b){

   return new CompareToBuilder()
     .append(a.getName(), b.getName())
     .append(a.getAddress(), b.getAddress())
     .toComparison();
}

The solutions like cmd /c pause cause a new command interpreter to start and run in the background. Although acceptable in some cases, this isn't really ideal.

The solutions using Read-Host force the user to press Enter and are not really "any key".

This solution will give you a true "press any key to continue" interface and will not start a new interpreter, which will essentially mimic the original pause command.

Write-Host "Press any key to continue..."
[void][System.Console]::ReadKey($true)

Try This Method

For Java :

EditText yourEditText = (EditText) findViewById(R.id.yourEditText);
yourEditText.setFilters(new InputFilter[] {
new InputFilter() {
    @Override
    public CharSequence filter(CharSequence cs, int start,
                int end, Spanned spanned, int dStart, int dEnd) {
        // TODO Auto-generated method stub
        if(cs.equals("")){ // for backspace
             return cs;
        }
        if(cs.toString().matches("[a-zA-Z ]+")){
             return cs;
        }
        return "";
    }
}});

For Kotlin :

 val yourEditText = findViewById<View>(android.R.id.yourEditText) as EditText
    val reges = Regex("^[0-9a-zA-Z ]+$")
    //this will allow user to only write letter and white space
    yourEditText.filters = arrayOf<InputFilter>(
        object : InputFilter {
            override fun filter(
                cs: CharSequence, start: Int,
                end: Int, spanned: Spanned?, dStart: Int, dEnd: Int,
            ): CharSequence? {
                if (cs == "") { // for backspace
                    return cs
                }
                return if (cs.toString().matches(reges)) {
                    cs
                } else ""
            }
        }
    )

The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.

If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True

Here is an example:

import pandas as pd
import numpy as np

my_series = pd.Series([1,2,2,3,3,3])

print(my_series.value_counts())
3    3
2    2
1    1
dtype: int64

Notice here that the item returned is a pandas.Series

In comparison, numpy.unique returns a tuple with two items, the unique values and the counts.

vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]

You can then combine these into a dictionary:

results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}

And then into a pandas.Series

print(pd.Series(results))
1    1
2    2
3    3
dtype: int64

You can use quotemeta (\Q \E) if your Perl is version 5.16 or later, but if below you can simply avoid using a regular expression at all.

For example, by using the index command:

if (index($text_to_search, $search_string) > -1) {
    print "wee";
}

Razor is a view engine for ASP.NET MVC, and also a template engine. Razor code and ASP.NET inline code (code mixed with markup) both get compiled first and get turned into a temporary assembly before being executed. Thus, just like C# and VB.NET both compile to IL which makes them interchangable, Razor and Inline code are both interchangable.

Therefore, it's more a matter of style and interest. I'm more comfortable with razor, rather than ASP.NET inline code, that is, I prefer Razor (cshtml) pages to .aspx pages.

Imagine that you want to get a Human class, and render it. In cshtml files you write:

<div>Name is @Model.Name</div>

While in aspx files you write:

<div>Name is <%= Human.Name %></div>

As you can see, @ sign of razor makes mixing code and markup much easier.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

Are you familiar with the DataSet class?

The DataSet can also load XML documents and you may find it easier to iterate.

http://msdn.microsoft.com/en-us/library/system.data.dataset.readxml.aspx

DataSet dt = new DataSet();
dt.ReadXml(@"c:\test.xml");
