For me the UnicodeWriter class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row() interface.

For example:

csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

works, while:

csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

will throw AttributeError: 'int' object has no attribute 'encode'.

As UnicodeWriter obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:

def to_utf8(lst):
    return [unicode(elem).encode('utf-8') for elem in lst]

...
csv_writer.writerow(to_utf8(row))

Or we can even monkey-patch csv_writer to add a write_utf8_row function - the exercise is left to the reader.

You need a split function:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create Function [dbo].[udf_Split]
(   
    @DelimitedList nvarchar(max)
    , @Delimiter nvarchar(2) = ','
)
RETURNS TABLE 
AS
RETURN 
    (
    With CorrectedList As
        (
        Select Case When Left(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
            + @DelimitedList
            + Case When Right(@DelimitedList, Len(@Delimiter)) <> @Delimiter Then @Delimiter Else '' End
            As List
            , Len(@Delimiter) As DelimiterLen
        )
        , Numbers As 
        (
        Select TOP( Coalesce(DataLength(@DelimitedList)/2,0) ) Row_Number() Over ( Order By c1.object_id ) As Value
        From sys.columns As c1
            Cross Join sys.columns As c2
        )
    Select CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen As Position
        , Substring (
                    CL.List
                    , CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen     
                    , CharIndex(@Delimiter, CL.list, N.Value + 1)                           
                        - ( CharIndex(@Delimiter, CL.list, N.Value) + CL.DelimiterLen ) 
                    ) As Value
    From CorrectedList As CL
        Cross Join Numbers As N
    Where N.Value <= DataLength(CL.List) / 2
        And Substring(CL.List, N.Value, CL.DelimiterLen) = @Delimiter
    )

With your split function, you would then use Cross Apply to get the data:

Select T.Col1, T.Col2
    , Substring( Z.Value, 1, Charindex(' = ', Z.Value) - 1 ) As AttributeName
    , Substring( Z.Value, Charindex(' = ', Z.Value) + 1, Len(Z.Value) ) As Value
From Table01 As T
    Cross Apply dbo.udf_Split( T.Col3, '|' ) As Z

Since you are doing this on a terminal and just want to inspect a record in a sane way, you can use a trick like this:

mongo | tee somefile

Use the session as normal - db.collection.find().pretty() or whatever you need to do, ignore the long output, and exit. A transcript of your session will be in the file tee wrote to.

Be mindful that the output might contain escape sequences and other garbage due to the mongo shell expecting an interactive session. less handles these gracefully.

Use command-line option -v or --invert-match,

ls -R |grep -v -E .*[\.exe]$\|.*[\.html]$

Here's a simple example of pretty printing JSON to the console in a nice way in Python, without requiring the JSON to be on your computer as a local file:

import pprint
import json 
from urllib.request import urlopen # (Only used to get this example)

# Getting a JSON example for this example 
r = urlopen("https://mdn.github.io/fetch-examples/fetch-json/products.json")
text = r.read() 

# To print it
pprint.pprint(json.loads(text))

I had the same error while including file from root of my project in codeigniter.I was using this in common.php of my project.

<?php include_once base_url().'csrf-magic-master/csrf-magic.php';  ?>

i changed it to

<?php include_once ('csrf-magic-master/csrf-magic.php');  ?>

Working fine now.

To Enter into crontab :

crontab -e

write this into the file:

0 */2 * * * python/php/java yourfilepath

Example :0 */2 * * * python ec2-user/home/demo.py

and make sure you have keep one blank line after the last cron job in your crontab file

Use the mapfile command:

mapfile -t myArray < file.txt

The error is using for -- the idiomatic way to loop over lines of a file is:

while IFS= read -r line; do echo ">>$line<<"; done < file.txt

See BashFAQ/005 for more details.

You can delete the props, but don't delete variables. delete abc; is invalid in ES5 (and throws with use strict).

You can assign it to null to set it for deletion to the GC (it won't if you have other references to properties)

Setting length property on an object does not change anything. (it only, well, sets the property)

for Bootstrap 4 version via CSS:

if you want to change the background color of balloon:

/* change style balloon */
.tooltip-inner {
    background-color: green !important;
    color: #fff;
}

if you want to change the arrow when appear in bottom position:

/* change style arrow */
.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .bs-tooltip-bottom .arrow::before {
    border-bottom-color: #f00;
}

Hope help you

I would use VMs. Create an XP (or whatever) VM using VMware Workstation or similar product, and snapshot it. That is your oldest version. Then perform the upgrades one at a time, and snapshot each time. Then you can switch to any snapshot you need later, or clone independent VMs based on all the snapshots so you can run them all at once. You probably want to test on different operating systems as well as different versions, so VMs generalize that solution as well rather than some one-off solution of hacking multiple IEs to coexist on a single instance of Windows.

So, if you were looking for command arguments, take a look at Tim's answer. If you just want to read a line from console:

#include <stdio.h>

int main()
{
  char string [256];
  printf ("Insert your full address: ");
  gets (string);
  printf ("Your address is: %s\n",string);
  return 0;
}

Yes, it is not secure, you can do buffer overrun, it does not check for end of file, it does not support encodings and a lot of other stuff. Actually I didn't even think whether it did ANY of this stuff. I agree I kinda screwed up :) But...when I see a question like "How to read a line from the console in C?", I assume a person needs something simple, like gets() and not 100 lines of code like above. Actually, I think, if you try to write those 100 lines of code in reality, you would do many more mistakes, than you would have done had you chosen gets ;)

Seems like you just forgot the comma to separate the classes. So based on your configuration the following will work:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration,\
    org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

Alternatively you could also define it as follow:

spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[2]=org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
spring.autoconfigure.exclude[3]=org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

A PIL only solution for creating a bi-level (black and white) image with a custom threshold:

from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')

With just

r = img.convert('1')
r.save('foo.png')

you get a dithered image.

From left to right the input image, the black and white conversion result and the dithered result:

You can click on the images to view the unscaled versions.

To check if a string represents a path or a file programatically, you should use API methods such as isFile(), isDirectory().

How does system understand whether there's a file or a folder?

I guess, the file and folder entries are kept in a data structure and it's managed by the file system.

Safe navigation operator or Existential Operator or Null Propagation Operator is supported in Angular Template. Suppose you have Component class

  myObj:any = {
    doSomething: function () { console.log('doing something'); return 'doing something'; },
  };
  myArray:any;
  constructor() { }

  ngOnInit() {
    this.myArray = [this.myObj];
  }

You can use it in template html file as following:

<div>test-1: {{  myObj?.doSomething()}}</div>
<div>test-2: {{  myArray[0].doSomething()}}</div>
<div>test-3: {{  myArray[2]?.doSomething()}}</div>

That doesn't work because a member function pointer cannot be handled like a normal function pointer, because it expects a "this" object argument.

Instead you can pass a static member function as follows, which are like normal non-member functions in this regard:

m_cRedundencyManager->Init(&CLoggersInfra::Callback, this);

The function can be defined as follows

static void Callback(int other_arg, void * this_pointer) {
    CLoggersInfra * self = static_cast<CLoggersInfra*>(this_pointer);
    self->RedundencyManagerCallBack(other_arg);
}

It was very tedious when I get same problem. When I got this problem, I uninstall my SQL Server 2008 but after installing the SQL Server 2008 again,I got the same problem. I was so tensed plus, I had not gotten any help from any site.

To over come this problem. Simply You Need to go on SQL Server Configuration Manager and then click On Protocols on left panel. If you running Network service just disable 'VIA' Protocol. And after that try to start your SQL service it will run successfully.

For jQuery 1.6+

$('.myCheckbox').prop('checked', true);
$('.myCheckbox').prop('checked', false);

For jQuery 1.5.x and below

$('.myCheckbox').attr('checked', true);
$('.myCheckbox').attr('checked', false);

To check,

$('.myCheckbox').removeAttr('checked');

As @wirey said appendTo should work, if not then you can try this:

$("#tblEntAttributes tbody").append(newRowContent);

The solution I came up with was to use the publishing feature.

File > Publish to the web...

Then in the URL you can just replace the .../edit path with .../pub

This solves the problem described in the question of breaking up a table with footnotes.

This is also simple crossbrowser solution:

var addEvent =  window.attachEvent||window.addEventListener;
var event = window.attachEvent ? 'onclick' : 'click';
addEvent(event, function(){
    alert('Hello!')
});

Instead of 'click' can be any event of course.

web2py has comet_messaging.py, which uses Tornado for websockets look at an example here: http://vimeo.com/18399381 and here vimeo . com / 18232653

A warning by which the compiler indicates that it cannot ensure type safety. The term "unchecked" warning is misleading. It does not mean that the warning is unchecked in any way. The term "unchecked" refers to the fact that the compiler and the runtime system do not have enough type information to perform all type checks that would be necessary to ensure type safety. In this sense, certain operations are "unchecked".

The most common source of "unchecked" warnings is the use of raw types. "unchecked" warnings are issued when an object is accessed through a raw type variable, because the raw type does not provide enough type information to perform all necessary type checks.

Example (of unchecked warning in conjunction with raw types):

TreeSet set = new TreeSet(); 
set.add("abc");        // unchecked warning 
set.remove("abc");

warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.TreeSet 
               set.add("abc");  
                      ^

When the add method is invoked the compiler does not know whether it is safe to add a String object to the collection. If the TreeSet is a collection that contains String s (or a supertype thereof), then it would be safe. But from the type information provided by the raw type TreeSet the compiler cannot tell. Hence the call is potentially unsafe and an "unchecked" warning is issued.

"unchecked" warnings are also reported when the compiler finds a cast whose target type is either a parameterized type or a type parameter.

Example (of an unchecked warning in conjunction with a cast to a parameterized type or type variable):

  class Wrapper<T> { 
  private T wrapped ; 
  public Wrapper (T arg) {wrapped = arg;} 
  ... 
  public Wrapper <T> clone() { 
    Wrapper<T> clon = null; 
     try {  
       clon = (Wrapper<T>) super.clone(); // unchecked warning 
     } catch (CloneNotSupportedException e) {  
       throw new InternalError();  
     } 
     try {  
       Class<?> clzz = this.wrapped.getClass(); 
       Method   meth = clzz.getMethod("clone", new Class[0]); 
       Object   dupl = meth.invoke(this.wrapped, new Object[0]); 
       clon.wrapped = (T) dupl; // unchecked warning 
     } catch (Exception e) {} 
     return clon; 
  } 
} 

warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: Wrapper <T> 
                  clon = ( Wrapper <T>)super.clone();  
                                                ^ 
warning: [unchecked] unchecked cast 
found   : java.lang.Object 
required: T 
                  clon. wrapped = (T)dupl;

A cast whose target type is either a (concrete or bounded wildcard) parameterized type or a type parameter is unsafe, if a dynamic type check at runtime is involved. At runtime, only the type erasure is available, not the exact static type that is visible in the source code. As a result, the runtime part of the cast is performed based on the type erasure, not on the exact static type.

In the example, the cast to Wrapper would check whether the object returned from super.clone is a Wrapper , not whether it is a wrapper with a particular type of members. Similarly, the casts to the type parameter T are cast to type Object at runtime, and probably optimized away altogether. Due to type erasure, the runtime system is unable to perform more useful type checks at runtime.

In a way, the source code is misleading, because it suggests that a cast to the respective target type is performed, while in fact the dynamic part of the cast only checks against the type erasure of the target type. The "unchecked" warning is issued to draw the programmer's attention to this mismatch between the static and dynamic aspect of the cast.

Please refer: What is an "unchecked" warning?

For print session data you do not need to use print_r() function every time .

If you use it then it will be non-readable format.Data will be looks very dirty.

But if you use my function all you have to do is to use p()-Funtion and pass data into it. //create new file into application/cms_helper.php and load helper cms into //autoload or on controller

/*Copy Code for p function from here and paste into cms_helper.php in application/helpers folder */

   //@parram $data-array,$d-if true then die by default it is false
   //@author Your name

    function p($data,$d = false){

          echo "<pre>"; 
             print_r($data);
          echo "</pre>"; 

        if($d == TRUE){
             die();
          } 
      }

Just remember to load cms_helper into your project or controller using $this->load->helper('cms'); use bellow code into your controller or model it will works just GREAT.

 p($this->session->all_userdata()); // it will apply pre to your sesison data and other array as  well

DAO is native to Access and by far the best for general use. ADO has its place, but it is unlikely that this is it.

 Dim rs As DAO.Recordset
 Dim db As Database
 Dim strSQL as String

 Set db=CurrentDB

 strSQL = "select * from table where some condition"

 Set rs = db.OpenRecordset(strSQL)

 Do While Not rs.EOF

    rs.Edit
    rs!SomeField = "Abc"
    rs!OtherField = 2
    rs!ADate = Date()
    rs.Update

    rs.MoveNext
Loop

If you want to update the user interface with activity result, you can't to use this.runOnUiThread(new Runnable() {} Doing this the UI won't refresh with new value. Instead, you can do this:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_CANCELED) {
        return;
    }

    global_lat = data.getDoubleExtra("LATITUDE", 0);
    global_lng = data.getDoubleExtra("LONGITUDE", 0);
    new_latlng = true;
}

@Override
protected void onResume() {
    super.onResume();

    if(new_latlng)
    {
        PhysicalTagProperties.this.setLocation(global_lat, global_lng);
        new_latlng=false;
    }
}

This seems silly but works pretty well.

Try:

-webkit-transition: all .2s linear, background-position 0;

This worked for me on something similar..

Kind of an old question, but I can give an answer updated for .NET Core 2.1 with C# 7 standards. Say I have a listing only in appsettings.Development.json such as:

"TestUsers": [
  {
    "UserName": "TestUser",
    "Email": "[email protected]",
    "Password": "P@ssw0rd!"
  },
  {
    "UserName": "TestUser2",
    "Email": "[email protected]",
    "Password": "P@ssw0rd!"
  }
]

I can extract them anywhere that the Microsoft.Extensions.Configuration.IConfiguration is implemented and wired up like so:

var testUsers = Configuration.GetSection("TestUsers")
   .GetChildren()
   .ToList()
    //Named tuple returns, new in C# 7
   .Select(x => 
         (
          x.GetValue<string>("UserName"), 
          x.GetValue<string>("Email"), 
          x.GetValue<string>("Password")
          )
    )
    .ToList<(string UserName, string Email, string Password)>();

Now I have a list of a well typed object that is well typed. If I go testUsers.First(), Visual Studio should now show options for the 'UserName', 'Email', and 'Password'.

See repmat in the documentation.

B = repmat(5,1,10)

Another way of doing this in plain bash is making use of the rev command like this:

cat file | rev | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Basically, you reverse the lines of the file, then split them with cut using space as the delimiter, take the first field that cut produces and then you reverse the token again, use tr -d to delete unwanted chars and tr again to replace newline chars with ,

Also, you can avoid the first cat by doing:

rev < file | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Where does pip installations happen in python?

I will give a windows solution which I was facing and took a while to solve.

First of all, in windows (I will be taking Windows as the OS here), if you do pip install <package_name>, it will be by default installed globally (if you have not activated a virtual enviroment). Once you activate a virtual enviroment and you are inside it, all pip installations will be inside that virtual enviroment.

pip is installing the said packages but not I cannot use them?

For this pip might be giving you a warning that the pip executables like pip3.exe, pip.exe are not on your path variable. For this you might add this path ( usually - C:\Users\<your_username>\AppData\Roaming\Programs\Python\ ) to your enviromental variables. After this restart your cmd, and now try to use your installed python package. It should work now.

<?php
$url=parse_url("http://domain.com/site/gallery/1?user=12#photo45 ");
echo $url["fragment"]; //This variable contains the fragment
?>

This is should work

what does this error mean? Object reference not set to an instance of an object.

exactly what it says, you are trying to use a null object as if it was a properly referenced object.

If you are using ASP.NET Core MVC project. This error message can be shown then you have the correct cshtml file in your Views folder but the action is missing in your controller.

Adding the missing action to the controller will fix it.

Modified answer from here.

If you have access to an Intel Secure Key compatible CPU, you can generate real random numbers and strings using these libraries: https://github.com/JebteK/RdRand and https://www.rdrand.com/

Just download the latest version from here, include Jebtek.RdRand and add a using statement for it. Then, all you need to do is this:

// Check to see if this is a compatible CPU
bool isAvailable = RdRandom.GeneratorAvailable();

// Generate 10 random characters
string key       = RdRandom.GenerateKey(10);

 // Generate 64 random characters, useful for API keys 
string apiKey    = RdRandom.GenerateAPIKey();

// Generate an array of 10 random bytes
byte[] b         = RdRandom.GenerateBytes(10);

// Generate a random unsigned int
uint i           = RdRandom.GenerateUnsignedInt();

If you don't have a compatible CPU to execute the code on, just use the RESTful services at rdrand.com. With the RdRandom wrapper library included in your project, you would just need to do this (you get 1000 free calls when you signup):

string ret = Randomizer.GenerateKey(<length>, "<key>");
uint ret   = Randomizer.GenerateUInt("<key>");
byte[] ret = Randomizer.GenerateBytes(<length>, "<key>");

For next examples assumed that you use C++11. Example with ranged-based for loops:

for (auto &attack : m_attack) // access by reference to avoid copying
{  
    if (attack->m_num == input)
    {
        attack->makeDamage();
    }
}

You should use const auto &attack depending on the behavior of makeDamage().

You can use std::for_each from standard library + lambdas:

std::for_each(m_attack.begin(), m_attack.end(),
        [](Attack * attack)
        {
            if (attack->m_num == input)
            {
                attack->makeDamage();
            }
        }
);

If you are uncomfortable using std::for_each, you can loop over m_attack using iterators:

for (auto attack = m_attack.begin(); attack != m_attack.end(); ++attack)
{  
    if (attack->m_num == input)
    {
        attack->makeDamage();
    }
}

Use m_attack.cbegin() and m_attack.cend() to get const iterators.

Start the second activity using intent (either use startActivity or startActivityForResult according to your requirements). Now when user press back button, the current activity on top will be closed and the previous will be shown.

Now Lets say you have two activities, one for selecting some settings for the user, like language, country etc, and after selecting it, the user clicks on Next button to go to the login form (for example) . Now if the login is unsuccessful, then the user will be on the login activity, what if login is successful ?

If login is successful, then you have to start another activity. It means a third activity will be started, and still there are two activities running. In this case, it will be good to use startActivityForResult. When login is successful, send OK data back to first activity and close login activity. Now when the data is received, then start the third activity and close the first activity by using finish.

Reactive Form

See at Stackblitz

Addition to the @Günter Zöchbauer's answer above, I tried as follows and it seems to be working but I'm not sure whether it is a efficient way.

I use valueChanges observable to listen for change events in the reactive form by subscribing to it. For special handling of backspace, I get the data from subscribe and check it with userForm.value.phone(from [formGroup]="userForm"). Because, at that moment, the data changes to the new value but the latter refers to the previous value because of not setting yet. If the data is less than previous value then the user should remove character from input. In this case, change pattern as follows:

from : newVal = newVal.replace(/^(\d{0,3})/, '($1)');

to : newVal = newVal.replace(/^(\d{0,3})/, '($1');

Otherwise, as Günter Zöchbauer mentioned above, deleting of non-numeric characters is not recognized because when we remove parentheses from input, digits still remain the same and added again parentheses from pattern match.

Controller:

import { Component,OnInit } from '@angular/core';
import { FormGroup,FormBuilder,AbstractControl,Validators } from '@angular/forms';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{

  constructor(private fb:FormBuilder) { 
    this.createForm();
  }

  createForm(){
    this.userForm = this.fb.group({
      phone:['',[Validators.pattern(/^\(\d{3}\)\s\d{3}-\d{4}$/),Validators.required]],
    });
  }

  ngOnInit() {
   this.phoneValidate();
  }

  phoneValidate(){
    const phoneControl:AbstractControl = this.userForm.controls['phone'];

    phoneControl.valueChanges.subscribe(data => {
    /**the most of code from @Günter Zöchbauer's answer.*/

    /**we remove from input but: 
       @preInputValue still keep the previous value because of not setting.
    */
    let preInputValue:string = this.userForm.value.phone;
    let lastChar:string = preInputValue.substr(preInputValue.length - 1);

    var newVal = data.replace(/\D/g, '');
    //when removed value from input
    if (data.length < preInputValue.length) {

      /**while removing if we encounter ) character,
         then remove the last digit too.*/
      if(lastChar == ')'){
         newVal = newVal.substr(0,newVal.length-1); 
      }
      if (newVal.length == 0) {
        newVal = '';
      } 
      else if (newVal.length <= 3) {
        /**when removing, we change pattern match.
        "otherwise deleting of non-numeric characters is not recognized"*/
        newVal = newVal.replace(/^(\d{0,3})/, '($1');
      } else if (newVal.length <= 6) {
        newVal = newVal.replace(/^(\d{0,3})(\d{0,3})/, '($1) $2');
      } else {
        newVal = newVal.replace(/^(\d{0,3})(\d{0,3})(.*)/, '($1) $2-$3');
      }
    //when typed value in input
    } else{


    if (newVal.length == 0) {
      newVal = '';
    } 
    else if (newVal.length <= 3) {
      newVal = newVal.replace(/^(\d{0,3})/, '($1)');
    } else if (newVal.length <= 6) {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})/, '($1) $2');
    } else {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})(.*)/, '($1) $2-$3');
    }

  }
    this.userForm.controls['phone'].setValue(newVal,{emitEvent: false});
  });
 }

}

Template:

<form [formGroup]="userForm"  novalidate>
  <div class="form-group">
    <label for="tel">Tel:</label>
    <input id="tel" formControlName="phone" maxlength="14">
  </div>
  <button [disabled]="userForm.status == 'INVALID'" type="submit">Send</button>
</form>

UPDATE

Is there a way to preserve cursor position while backspacing in the middle of the string? Currently, it jumps back to the end.

Define an id <input id="tel" formControlName="phone" #phoneRef> and renderer2#selectRootElement to get the native element in the component.

So we can get the cursor position using:

let start = this.renderer.selectRootElement('#tel').selectionStart;
let end = this.renderer.selectRootElement('#tel').selectionEnd;

and then we can apply it after the input is updated to new value:

this.userForm.controls['phone'].setValue(newVal,{emitEvent: false});
//keep cursor the appropriate position after setting the input above.
this.renderer.selectRootElement('#tel').setSelectionRange(start,end);

UPDATE 2

It's probably better to put this sort of logic inside a directive rather than in the component

I also put the logic into a directive. This makes it easier to apply it to other elements.

See at Stackblitz

Note: It is specific to (123) 123-4567 pattern.

You can use for Debian/Ubuntu:

dpkg -l|grep kafka

Expected result should to be like:

this works for me new_df = df[df.loc[:]!=0].dropna()

Using this code it will be responsive also.

From the terminal (osx) I usually use

cordova plugin -l | xargs cordova plugins rm

Pipe, pipe everything!

To expand a bit: this command will loop through the results of cordova plugin -l and feed it to cordova plugins rm.

xargs is one of those commands that you wonder why you didn't know about before. See this tut.

I just want to share some of my experience with the accepted answer. I did all steps and all was fine before I ran the last step:

git svn dcommit

$ git svn dcommit

Use of uninitialized value $u in substitution (s///) at /usr/lib/perl5/vendor_perl/5.22/Git/SVN.pm line 101.

Use of uninitialized value $u in concatenation (.) or string at /usr/lib/perl5/vendor_perl/5.22/Git/SVN.pm line 101. refs/remotes/origin/HEAD: 'https://192.168.2.101/svn/PROJECT_NAME' not found in ''

I found the thread https://github.com/nirvdrum/svn2git/issues/50 and finally the solution which I applied in the following file in line 101 /usr/lib/perl5/vendor_perl/5.22/Git/SVN.pm

I replaced

$u =~ s!^\Q$url\E(/|$)!! or die

with

if (!$u) {
    $u = $pathname;
} 
else {
       $u =~ s!^\Q$url\E(/|$)!! or die
      "$refname: '$url' not found in '$u'\n";
}

This fixed my issue.

Use $_SERVER['REQUEST_METHOD'].

if you want to use parentheses in laravel 4 and don't forget return
In Laravel 4 (at least) you need to use $a, $b in parentheses as in the example

$a = 1;
$b = 1;
$c = 1;
$d = 1;
Model::where(function ($query) use ($a, $b) {
    return $query->where('a', '=', $a)
          ->orWhere('b', '=', $b);
})->where(function ($query) use ($c, $d) {
    return $query->where('c', '=', $c)
          ->orWhere('d', '=', $d);
});

This is my result:

If you can't turn it off, here is what I usually do:

get_magic_quotes_gpc() ? $_POST['username'] : mysql_real_escape_string($_POST['username']);

It will be placed in the database in its proper format.

First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");

Then inject the mock into m_orderSvc and call your method.

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Finally, verify that the mock was called properly:

verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");

I built this upon F.J.s excellent answer:

import re

def multiple_replacer(*key_values):
    replace_dict = dict(key_values)
    replacement_function = lambda match: replace_dict[match.group(0)]
    pattern = re.compile("|".join([re.escape(k) for k, v in key_values]), re.M)
    return lambda string: pattern.sub(replacement_function, string)

def multiple_replace(string, *key_values):
    return multiple_replacer(*key_values)(string)

One shot usage:

>>> replacements = (u"café", u"tea"), (u"tea", u"café"), (u"like", u"love")
>>> print multiple_replace(u"Do you like café? No, I prefer tea.", *replacements)
Do you love tea? No, I prefer café.

Note that since replacement is done in just one pass, "café" changes to "tea", but it does not change back to "café".

If you need to do the same replacement many times, you can create a replacement function easily:

>>> my_escaper = multiple_replacer(('"','\\"'), ('\t', '\\t'))
>>> many_many_strings = (u'This text will be escaped by "my_escaper"',
                       u'Does this work?\tYes it does',
                       u'And can we span\nmultiple lines?\t"Yes\twe\tcan!"')
>>> for line in many_many_strings:
...     print my_escaper(line)
... 
This text will be escaped by \"my_escaper\"
Does this work?\tYes it does
And can we span
multiple lines?\t\"Yes\twe\tcan!\"

Improvements:

• turned code into a function
• added multiline support
• fixed a bug in escaping
• easy to create a function for a specific multiple replacement

Enjoy! :-)

If you're using jQuery, it's as simple as this:

$('form').attr('action', 'myNewActionTarget.html');

You can try using parentheses around the OR expressions to make sure your query is interpreted correctly, or more concisely, use IN:

SELECT ads.*, location.county 
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1 
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)

If you want to table do following steps:-

views.py:

def view_info(request):
    objs=Model_name.objects.all()
    ............
    return render(request,'template_name',{'objs':obj})

.html page

 {% for item in objs %}
    <tr> 
         <td>{{ item.field1 }}</td>
         <td>{{ item.field2 }}</td>
         <td>{{ item.field3 }}</td>
         <td>{{ item.field4 }}</td>
    </tr>
       {% endfor %}

This is my best shot!!

And do not use inputStream.transferTo(...) because is too generic. Your code performance will be better if you control your buffer memory.

public static void transfer(InputStream in, OutputStream out, int buffer) throws IOException {
    byte[] read = new byte[buffer]; // Your buffer size.
    while (0 < (buffer = in.read(read)))
        out.write(read, 0, buffer);
}

I use it with this (improvable) method when I know in advance the size of the stream.

public static void transfer(int size, InputStream in, OutputStream out) throws IOException {
    transfer(in, out,
            size > 0xFFFF ? 0xFFFF // 16bits 65,536
                    : size > 0xFFF ? 0xFFF// 12bits 4096
                            : size < 0xFF ? 0xFF // 8bits 256
                                    : size
    );
}

Working on El Capitan 10.11.1, the steps I followed are

brew install cask    
brew tap homebrew/science    
brew install r

use getBoundingClientRect if $el is the actual DOM object:

var top = $el.getBoundingClientRect().top;

JSFiddle

Fiddle will show that this will get the same value that jquery's offset top will give you

Edit: as mentioned in comments this does not account for scrolled content, below is the code that jQuery uses

https://github.com/jquery/jquery/blob/master/src/offset.js (5/13/2015)

offset: function( options ) {
    //...

    var docElem, win, rect, doc,
        elem = this[ 0 ];

    if ( !elem ) {
        return;
    }

    rect = elem.getBoundingClientRect();

    // Make sure element is not hidden (display: none) or disconnected
    if ( rect.width || rect.height || elem.getClientRects().length ) {
        doc = elem.ownerDocument;
        win = getWindow( doc );
        docElem = doc.documentElement;

        return {
            top: rect.top + win.pageYOffset - docElem.clientTop,
            left: rect.left + win.pageXOffset - docElem.clientLeft
        };
    }
}

Try to add a s after http

Like this:

It works for me

You could manually adjust the spacing using plt.subplots_adjust(top=0.85):

import numpy as np
import matplotlib.pyplot as plt

f = np.random.random(100)
g = np.random.random(100)
fig = plt.figure()
fig.suptitle('Long Suptitle', fontsize=24)
plt.subplot(121)
plt.plot(f)
plt.title('Very Long Title 1', fontsize=20)
plt.subplot(122)
plt.plot(g)
plt.title('Very Long Title 2', fontsize=20)
plt.subplots_adjust(top=0.85)
plt.show()

If you don't know the main activity, then the package name can be used to launch the application.

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
if (launchIntent != null) { 
    startActivity(launchIntent);//null pointer check in case package name was not found
}

If you're running python3, you'll have to do:

pip3 install lxml

First, you can use sql command show global variables like 'innodb_buffer%'; to check the buffer size.

Solution is find your my.cnf file and add,

[mysqld]_x000D_
innodb_buffer_pool_size=1G # depends on your data and machine

DO NOT forget to add [mysqld], otherwise, it won't work.

In my case, ubuntu 16.04, my.cnf is located under the folder /etc/mysql/.

Hmm, it looks to me like CURLOPT_TIMEOUT defines the amount of time that any cURL function is allowed to take to execute. I think you should actually be looking at CURLOPT_CONNECTTIMEOUT instead, since that tells cURL the maximum amount of time to wait for the connection to complete.

Using tidyverse

df %>% tidyr::gather("id", "value", 1:4) %>% 
  ggplot(., aes(Xax, value))+
  geom_point()+
  geom_smooth(method = "lm", se=FALSE, color="black")+
  facet_wrap(~id)

DATA

df<- read.table(text =c("

for just translating one char into another throughout a string, tr is the best tool:

tr '\\' '/'

For latest version of Intellij IDEA users there is an option to download JDK directly from the IDE: https://www.jetbrains.com/help/idea/sdk.html#jdk-from-ide

You do it like this:

df = read.table("file.txt", nrows=1, header=TRUE, sep="\t", stringsAsFactors=FALSE)
colClasses = as.list(apply(df, 2, class))
needCols = c("Year", "Jan", "Feb", "Mar", "Apr", "May", "Jun")
colClasses[!names(colClasses) %in% needCols] = list(NULL)
df = read.table("file.txt", header=TRUE, colClasses=colClasses, sep="\t", stringsAsFactors=FALSE)

Along the same lines as SCFrench's answer, but with a more C# style spin..

I would (and often do) make a class containing multiple static methods. For example:

classdef Statistics

    methods(Static)
        function val = MyMean(data)
            val = mean(data);
        end

        function val = MyStd(data)
            val = std(data);
        end
    end

end

As the methods are static you don't need to instansiate the class. You call the functions as follows:

data = 1:10;

mean = Statistics.MyMean(data);
std = Statistics.MyStd(data);     

In addition to @CB Bailey's answer:

I tried to remove multiple folders (in subfolders) named et-cache (caching folder from Wordpress divi theme) from the index and from being tracked.

I added

et-cache/

to the .gitignore file. But

git rm -r --cached et-cache

resulted in an error:

fatal: pathspec 'et-cache' did not match any files

So the solution was to use powershell:

Get-ChildItem et-cache -Recurse |% {git rm -r --cached $_.FullName}

This searches for all subfolders named et-cache. Each of the folders path (fullname) is then used to remove it from tracking in git.

'email' => [
    'required',
    Rule::exists('staff')->where(function ($query) {
        $query->where('account_id', 1);
    }),
],

'email' => [
    'required',
    Rule::unique('users')->ignore($user->id)->where(function ($query) {
        $query->where('account_id', 1);
    })
],

Parse the SMBIOS yourself and hash it to an arbitrary length. See the PDF specification for all SMBIOS structures available.

To query the SMBIOS info from Windows you could use EnumSystemFirmwareEntries, EnumSystemFirmwareTables and GetSystemFirmwareTable.

IIRC, the "unique id" from the CPUID instruction is deprecated from P3 and newer.

If you need to call a shell command from a Python notebook (like Jupyter, Zeppelin, Databricks, or Google Cloud Datalab) you can just use the ! prefix.

For example,

!ls -ilF

If you want to match anything after a word stop an not only at the start of the line you may use : \bstop.*\b - word followed by line

Or if you want to match the word in the string use \bstop[a-zA-Z]* - only the words starting with stop

Or the start of lines with stop ^stop[a-zA-Z]* for the word only - first word only
The whole line ^stop.* - first line of the string only

And if you want to match every string starting with stop including newlines use : /^stop.*/s - multiline string starting with stop

Like this:

<ComboBox Text="MyCombo">
<ComboBoxItem  Name="cbi1">Item1</ComboBoxItem>
<ComboBoxItem  Name="cbi2">Item2</ComboBoxItem>
<ComboBoxItem  Name="cbi3">Item3</ComboBoxItem>
</ComboBox>

alert (product.UnitName + " " + product.UnitPrice + " " + product.Stock)

or else create a toString() method on your object and call

alert(product.toString())

But I have to agree with other posters - if it is debugging you're going for then firebug or F12 on IE9 or chrome and using console.log is the way to go

adb shell getprop ro.build.version.sdk

If you want to see the whole list of parameters just type:

adb shell getprop

If you take 5 minutes to download visual studio and make a Console Application for this, your problem is solved.

Here's yet another answer offering commentary on how Muis, Abdullah Al-Ageel and Flip's answer are all mathematically the same thing except written differently.

Sure, we have José Manuel Ramos's analysis explaining how rounding errors affect each slightly differently, but that's implementation dependent and would change based on how each answer were applied to code.

There is however a rather big difference

It's in Muis's N, Flip's k, and Abdullah Al-Ageel's n. Abdullah Al-Ageel doesn't quite explain what n should be, but N and k differ in that N is "the number of samples where you want to average over" while k is the count of values sampled. (Although I have doubts to whether calling N the number of samples is accurate.)

And here we come to the answer below. It's essentially the same old exponential weighted moving average as the others, so if you were looking for an alternative, stop right here.

Exponential weighted moving average

Initially:

average = 0
counter = 0

For each value:

counter += 1
average = average + (value - average) / min(counter, FACTOR)

The difference is the min(counter, FACTOR) part. This is the same as saying min(Flip's k, Muis's N).

FACTOR is a constant that affects how quickly the average "catches up" to the latest trend. Smaller the number the faster. (At 1 it's no longer an average and just becomes the latest value.)

This answer requires the running counter counter. If problematic, the min(counter, FACTOR) can be replaced with just FACTOR, turning it into Muis's answer. The problem with doing this is the moving average is affected by whatever average is initiallized to. If it was initialized to 0, that zero can take a long time to work its way out of the average.

How it ends up looking

I recommend PowerGrep

I had to do an e-discovery project several years ago. I found that fisdstr had some limitations, most especially fisdstr would eventually fail

the script had to search across thousands of files using a couple of dozen search terms/phrases.

Cygwin's grep worked much better, it didn't choke often, but ultimately I went to PowerGrep because the graphical interface made it much easier to tell when and where it crashed, and also it was really easy to edit in all the conditionals and output that I wanted. Ultimately PowerGrep was the most reliable of the three.

Something like this worked for me (references columns C and D from the row 8 till the end of the columns, in Excel 2013 if relevant):

=SUMIFS(INDIRECT(ADDRESS(ROW(D$8), COLUMN())&":"&ADDRESS(ROWS($C:$C), COLUMN())),INDIRECT("C$8:C"&ROWS($C:$C)),$C$2)

You can make a view with a different dtype, and then copy in-place into the view:

import numpy as np
x = np.arange(10, dtype='int32')
y = x.view('float32')
y[:] = x

print(y)

yields

array([ 0.,  1.,  2.,  3.,  4.,  5.,  6.,  7.,  8.,  9.], dtype=float32)

To show the conversion was in-place, note that copying from x to y altered x:

print(x)

prints

array([         0, 1065353216, 1073741824, 1077936128, 1082130432,
       1084227584, 1086324736, 1088421888, 1090519040, 1091567616])

First the bigint(20) not null auto_increment will not work, simply use bigserial primary key. Then datetime is timestamp in PostgreSQL. All in all:

CREATE TABLE article (
    article_id bigserial primary key,
    article_name varchar(20) NOT NULL,
    article_desc text NOT NULL,
    date_added timestamp default NULL
);

version 4.8.0

$('textarea').data('ckeditorInstance').getData();

Check out this post

According to it

No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

You can use CertMgr to add a certificate as a trusted publisher or if it is self-signed, as a root certificate

CertMgr.exe /add CertificateFileName.cer /s /r localMachine root

See Microsoft's documentation here:

Just change the directory to another one and come back. Probably that one has been deleted or moved.

You can get the phone device name from the

BluetoothAdapter

In case phone doesn't support Bluetooth, then you have to construct the device name from

android.os.Build class

Here is the sample code to get the phone device name.

public String getPhoneDeviceName() {  
        String name=null;
        // Try to take Bluetooth name
        BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
        if (adapter != null) {
            name = adapter.getName();
        }

        // If not found, use MODEL name
        if (TextUtils.isEmpty(name)) {
            String manufacturer = Build.MANUFACTURER;
            String model = Build.MODEL;
            if (model.startsWith(manufacturer)) {

Preventing a crash caused by the caller sending in an invalid pointer is a good way to make silent bugs that are hard to find.

Isn't it better for the programmer using your API to get a clear message that his code is bogus by crashing it rather than hiding it?

If you want to automate the creating of a custom divergent colormap commonly used for surface plots, this module combined with @unutbu method worked well for me.

def diverge_map(high=(0.565, 0.392, 0.173), low=(0.094, 0.310, 0.635)):
    '''
    low and high are colors that will be used for the two
    ends of the spectrum. they can be either color strings
    or rgb color tuples
    '''
    c = mcolors.ColorConverter().to_rgb
    if isinstance(low, basestring): low = c(low)
    if isinstance(high, basestring): high = c(high)
    return make_colormap([low, c('white'), 0.5, c('white'), high])

The high and low values can be either string color names or rgb tuples. This is the result using the surface plot demo:

Go to Settings -> Style Configurator

Select Theme: Choose whichever you like best (the top two are easiest to read by most people's preference)

Try width:inherit to make the image take the width of it's container <div>. It will stretch/shrink it's height to maintain proportion. Don't set the height in the <div>, it will size to fit the image height.

img {
    width:inherit;
}

.item {
    border:1px solid pink;
    width: 120px;
    float: left;
    margin: 3px;
    padding: 3px;
}

Necromancing.
I usually just create a class, which I can wrap around main in an IDisposable.
So I can log the console output to a file without modifying the rest of the code.
That way, I have the output in both the console and for later reference in a text-file.

public class Program
{

    public static async System.Threading.Tasks.Task Main(string[] args)
    {
        using (ConsoleOutputMultiplexer co = new ConsoleOutputMultiplexer())
        {
            // Do something here
            System.Console.WriteLine("Hello Logfile and Console 1 !");
            System.Console.WriteLine("Hello Logfile and Console 2 !");
            System.Console.WriteLine("Hello Logfile and Console 3 !");
        } // End Using co 


        System.Console.WriteLine(" --- Press any key to continue --- ");
        System.Console.ReadKey();

        await System.Threading.Tasks.Task.CompletedTask;
    } // End Task Main

From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?

For all Windows platforms:

1) Download the .WHL package install file.

2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].

3) Make sure the latest version of pip.EXE is now installed. At this time of posting:

pip.EXE --version

  pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

4) Run pip.EXE in an Admin command shell.

 - Open an Admin privileged command shell.

 > easy_install.EXE --upgrade  pip

 - Check the pip.EXE version:
 > pip.EXE --version

 pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

 > pip.EXE install --use-wheel --no-index 
     --find-links="X:\path to wheel file\DownloadedWheelFile.whl"

Be sure to double-quote paths or path\filenames with embedded spaces in them ! Alternatively, use the MSW 'short' paths and filenames.

To anyone who came across this question who are using SQL Server Database and still having an exception thrown even after adding the following annotation on the int primary key

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }

Please check your SQL, make sure your the primary key has 'IDENTITY(startValue, increment)' next to it,

CREATE TABLE [dbo].[User]
(
    [Id] INT IDENTITY(1,1) NOT NULL PRIMARY KEY
)

This will make the database increments the id every time a new row is added, with a starting value of 1 and increments of 1.

I accidentally overlooked that in my SQL which cost me an hour of my life, so hopefully this helps someone!!!

I found this article and tried the tutorial. Basically, you can use the date constructor to parse a date, then write get the seconds from the getTime() method

var d=new Date("October 13, 1975 11:13:00");
document.write(d.getTime() + " milliseconds since 1970/01/01");

Does this work?

You would be better off using a DOM parser for this kind of HTML parsing. Consider this code:

$html = '<img id="12" border="0" src="/images/image.jpg"
         alt="Image" width="100" height="100" />';
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html); // loads your html
$xpath = new DOMXPath($doc);
$nodelist = $xpath->query("//img"); // find your image
$node = $nodelist->item(0); // gets the 1st image
$value = $node->attributes->getNamedItem('src')->nodeValue;
echo "src=$value\n"; // prints src of image

OUTPUT:

src=/images/image.jpg

For multiple functions use this. This is very helpful to use animations or Activity loader for static functions or any UI Update.

DispatchQueue.main.asyncAfter(deadline: .now() + 0.9) {
            // Call your function 1
            DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
                // Call your function 2
            }
        }

For example - Use a animation before a tableView reloads. Or any other UI update after the animation.

*// Start your amination* 
self.startAnimation()
DispatchQueue.main.asyncAfter(deadline: .now() + 0.9) {
                *// The animation will execute depending on the delay time*
                self.stopAnimation()
                DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
                    *// Now update your view*
                     self.fetchData()
                     self.updateUI()
                }
            }

What i did to solve this problem in the terminal(Ubuntu 18.04):

openssl s_client -showcerts -servername www.github.com -connect www.github.com:443

I got two chunks of certificate chunks. And i copied the certificate chunks to my certificate file to /etc/ssl/certs/ca-certificates.crt.

I know this question asked quite long time ago but for the new users of this question. Please read this article where contains complete description on upcasting, downcasting and use of instanceof operator

• There's no need to upcast manually, it happens on its own:

  Mammal m = (Mammal)new Cat(); equals to Mammal m = new Cat();

• But downcasting must always be done manually:

  Cat c1 = new Cat();      
  Animal a = c1;      //automatic upcasting to Animal
  Cat c2 = (Cat) a;    //manual downcasting back to a Cat
  

Why is that so, that upcasting is automatical, but downcasting must be manual? Well, you see, upcasting can never fail. But if you have a group of different Animals and want to downcast them all to a Cat, then there's a chance, that some of these Animals are actually Dogs, and process fails, by throwing ClassCastException. This is where is should introduce an useful feature called "instanceof", which tests if an object is instance of some Class.

 Cat c1 = new Cat();         
    Animal a = c1;       //upcasting to Animal
    if(a instanceof Cat){ // testing if the Animal is a Cat
        System.out.println("It's a Cat! Now i can safely downcast it to a Cat, without a fear of failure.");        
        Cat c2 = (Cat)a;
    }

For more information please read this article

Append ll suffix to hex digits for 64-bit (long long int), or ull suffix for unsigned 64-bit (unsigned long long)

Based on the previous comment and further considering I created an extension of TestWather which you can use in your JUnit test methods with this:

public class ImportUtilsTest {
    private static final Logger LOGGER = Logger.getLogger(ImportUtilsTest.class);

    @Rule
    public TestWatcher testWatcher = new JUnitHelper(LOGGER);

    @Test
    public test1(){
    ...
    }
}

The test helper class is the next:

public class JUnitHelper extends TestWatcher {
private Logger LOGGER;

public JUnitHelper(Logger LOGGER) {
    this.LOGGER = LOGGER;
}

@Override
protected void starting(final Description description) {
    LOGGER.info("STARTED " + description.getMethodName());
}

@Override
protected void succeeded(Description description) {
    LOGGER.info("SUCCESSFUL " + description.getMethodName());
}

@Override
protected void failed(Throwable e, Description description) {
    LOGGER.error("FAILURE " + description.getMethodName());
}
}

Enjoy!

I would NEVER use chars. I’ve had this debate with many people and they always bring up the tired cliché that char is faster. Well I say, how much faster? What are we talking about here, milliseconds, seconds and if so how many? You’re telling me because someone claims its a few milliseconds faster, we should introduce tons of hard to fix bugs into the system?

So here are some issues you will run into:

Every field will be padded, so you end up with code forever that has RTRIMS everywhere. This is also a huge disk space waste for the longer fields.

Now let’s say you have the quintessential example of a char field of just one character but the field is optional. If somebody passes an empty string to that field it becomes one space. So when another application/process queries it, they get one single space, if they don’t use rtrim. We’ve had xml documents, files and other programs, display just one space, in optional fields and break things.

So now you have to ensure that you’re passing nulls and not empty string, to the char field. But that’s NOT the correct use of null. Here is the use of null. Lets say you get a file from a vendor

Name|Gender|City

Bob||Los Angeles

If gender is not specified than you enter Bob, empty string and Los Angeles into the table. Now lets say you get the file and its format changes and gender is no longer included but was in the past.

Name|City

Bob|Seattle

Well now since gender is not included, I would use null. Varchars support this without issues.

Char on the other hand is different. You always have to send null. If you ever send empty string, you will end up with a field that has spaces in it.

I could go on and on with all the bugs I’ve had to fix from chars and in about 20 years of development.

just indent your code correctly:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            return period
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            return 0
        else:   
            return period

You need to understand that the break statement in your example will exit the infinite loop you've created with while True. So when the break condition is True, the program will quit the infinite loop and continue to the next indented block. Since there is no following block in your code, the function ends and don't return anything. So I've fixed your code by replacing the break statement by a return statement.

Following your idea to use an infinite loop, this is the best way to write it:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            break
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            period = 0
            break

    return period

It depends in what mode you are compiling. long long is not part of the C++ standard but only (usually) supported as extension. This affects the type of literals. Decimal integer literals without any suffix are always of type int if int is big enough to represent the number, long otherwise. If the number is even too big for long the result is implementation-defined (probably just a number of type long int that has been truncated for backward compatibility). In this case you have to explicitly use the LL suffix to enable the long long extension (on most compilers).

The next C++ version will officially support long long in a way that you won't need any suffix unless you explicitly want the force the literal's type to be at least long long. If the number cannot be represented in long the compiler will automatically try to use long long even without LL suffix. I believe this is the behaviour of C99 as well.

The problem you're having is that you're passing incompatible formats from a formatted java.util.Date to construct an instance of java.sql.Date, which don't behave in the same way when using valueOf() since they use different formats.

I also can see that you're aiming to persist hours and minutes, and I think that you'd better change the data type to java.sql.Timestamp, which supports hours and minutes, along with changing your database field to DATETIME or similar (depending on your database vendor).

Anyways, if you want to change from java.util.Date to java.sql.Date, I suggest to use

java.util.Date date = Calendar.getInstance().getTime();
java.sql.Date sqlDate = new java.sql.Date(date.getTime()); 
// ... more code here
prs.setDate(sqlDate);

Microsoft Access and LibreOffice Base can open a spreadsheet as a source and run sql queries on it. That would be the easiest way to run all kinds of queries, and avoid the mess of running macros or writing code.

Excel also has autofilters and data sorting that will accomplish a lot of simple queries like your example. If you need help with those features, Google would be a better source for tutorials than me.

public class BOX
{
    double height, length, breadth;

    public static bool operator == (BOX b1, BOX b2)
    {
        if (b1 is null)
            return b2 is null;

        return b1.Equals(b2);
    }

    public static bool operator != (BOX b1, BOX b2)
    {
        return !(b1 == b2);
    }

    public override bool Equals(object obj)
    {
        if (obj == null)
            return false;

        return obj is BOX b2? (length == b2.length && 
                               breadth == b2.breadth && 
                               height == b2.height): false;

    }

    public override int GetHashCode()
    {
        return (height,length,breadth).GetHashCode();
    }
}

Css below should do the trick.

After the second line the, text will contain ...

line-height: 1em;
max-height: 2em;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;

IMHO the coolest way is to go via WebDAV (without Network Folder, as this is often not permitted). This can be accomplished via ActiveX Data Objects as layed out in this excellent article excellent article (code can be used directly in Excel, used the concept recently).

Hope this helps!

To self-hide already running script you'll need getCmdPid.bat and windowoMode.bat

@echo off

echo self minimizing
call getCmdPid.bat
call windowMode.bat -pid %errorlevel% -mode hidden

echo --other commands--
pause

Here I've compiled all ways that I know to start a hidden process with batch without external tools.With a ready to use scripts (some of them rich on options) , and all of them form command line.Where is possible also the PID is returned .Used tools are IEXPRESS,SCHTASKS,WScript.Shell,Win32_Process and JScript.Net - but all of them wrapped in a .bat files.

You have to use == to compare (or even ===, if you want to compare types). A single = is for assignment.

if (one == 'rock' && two == 'rock') {
    console.log('Tie! Try again!');
}

As of Graph API 2.3 Facebook provides code similar to the following for the comments plugin:

<div class="fb-comments"
    data-href="http://absolute.url"
    data-numposts="5">
</div>

Add a data-width="100%" to make it semi-responsive as follows:

<div class="fb-comments"
    data-href="http://absolute.url"
    data-numposts="5"
    data-width="100%">
</div>

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

I faced the same problem and solved it by the following code .

 public static Calendar getCalendarFromISO(String datestring) {
    Calendar calendar = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault()) ;
    SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());
    try {
        Date date = dateformat.parse(datestring);
        date.setHours(date.getHours() - 1);
        calendar.setTime(date);

        String test = dateformat.format(calendar.getTime());
        Log.e("TEST_TIME", test);

    } catch (ParseException e) {
        e.printStackTrace();
    }

    return calendar;
}

Earlier I was using SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ", Locale.getDefault());

But later i found the main cause of the exception was the yyyy-MM-dd'T'HH:mm:ss.SSSZ ,

So i used

SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());

It worked fine for me .

Do you need to parse arbitrary JSON structures, or just data that's specific to your application. If the latter, you can make it a lot lighter and more efficient by not having to generate any hash table/map structure mapping JSON keys to values; you can instead just store the data directly into struct fields or whatever.

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.

User.delete_all(condition: 'value') will allow you to delete records without a primary key

Note: from @hammady's comment, user.destroy won't work if User model has no primary key.

Note 2: From @pavel-chuchuva's comment, destroy_all with conditions and delete_all with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

Please see my answer here. As dreamwerx.myopenid.com points out, it is possible to do this with SimpleXML, but the DOM extension would be the better and more flexible way. Additionally there is a third way: using XMLWriter. It's much more simple to use than the DOM and therefore it's my preferred way of writing XML documents from scratch.

$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
    $w->writeAttribute("ah", "OK");
    $w->text('Wow, it works!');
$w->endElement();
echo htmlentities($w->outputMemory(true));

By the way: DOM stands for Document Object Model; this is the standardized API into XML documents.

If the delete is recent enough (Like an Oh-NO! moment) you should still have a message:

Deleted branch <branch name> (was abcdefghi).

you can still run:

git checkout abcdefghi

git checkout -b <some new branch name or the old one>

In this simple case you can use vars():

an = Animal()
attrs = vars(an)
# {'kids': 0, 'name': 'Dog', 'color': 'Spotted', 'age': 10, 'legs': 2, 'smell': 'Alot'}
# now dump this in some way or another
print(', '.join("%s: %s" % item for item in attrs.items()))

If you want to store Python objects on the disk you should look at shelve — Python object persistence.

use style instead like

<div style="display:none;"></div>

If you use apachectl to start or stop, then you can find it with this command

apachectl -t -D DUMP_RUN_CFG

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

The KeyTool is part of the JDK. You'll find it, assuming you installed the JDK with default settings, in $JAVA_HOME/bin

Mark Russinovich wrote a terrific tool called AccessChk that lets you get this information from the command line. No installation is necessary.

http://technet.microsoft.com/en-us/sysinternals/bb664922.aspx

For example:

accesschk.exe /accepteula -q -a SeServiceLogonRight

Returns this for me:

IIS APPPOOL\DefaultAppPool
IIS APPPOOL\Classic .NET AppPool
NT SERVICE\ALL SERVICES

By contrast, whoami /priv and whoami /all were missing some entries for me, like SeServiceLogonRight.

Pure CSS method

It is possible to center a video inside an element just like a cover sized background-image without JS using the object-fit attribute or CSS Transforms.

2021 answer: object-fit

As pointed in the comments, it is possible to achieve the same result without CSS transform, but using object-fit, which I think it's an even better option for the same result:

.video-container {
    height: 300px;
    width: 300px;
    position: relative;
}

.video-container video {
  width: 100%;
  height: 100%;
  position: absolute;
  object-fit: cover;
  z-index: 0;
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
    <video autoplay muted loop>
        <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
    </video>
    <div class="caption">
      <h2>Your caption here</h2>
    </div>
</div>

Previous answer: CSS Transform

You can set a video as a background to any HTML element easily thanks to transform CSS property.

Note that you can use the transform technique to center vertically and horizontally any HTML element.

.video-container {
  height: 300px;
  width: 300px;
  overflow: hidden;
  position: relative;
}

.video-container video {
  min-width: 100%;
  min-height: 100%;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translateX(-50%) translateY(-50%);
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
  <video autoplay muted loop>
    <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
  </video>
  <div class="caption">
    <h2>Your caption here</h2>
  </div>
</div>

The errors in ASP.Net are saved on the Server.GetLastError property,

Or i would put a label on the asp.net page for displaying the error.

try
{
    do something
}
catch (YourException ex)
{
    errorLabel.Text = ex.Message;
    errorLabel.Visible = true;
}

CREATE TABLE fractest( c1 TIME(3), c2 DATETIME(3), c3 TIMESTAMP(3) );

INSERT INTO fractest VALUES
('17:51:04.777', '2018-09-08 17:51:04.777', '2018-09-08 17:51:04.777');

Use @Column annotation and define its length attribute. Check Hibernate's documentation for references (section 2.2.2.3).

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

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

That's a bit of informal terminology.

As far as Git is concerned, every other repository is just a remote.

Generally speaking, upstream is where you cloned from (the origin). Downstream is any project that integrates your work with other works.

The terms are not restricted to Git repositories.

For instance, Ubuntu is a Debian derivative, so Debian is upstream for Ubuntu.

you can use

android.R.drawable.xxx

(use autocomplete to see whats in there)

Or download the stuff from http://developer.android.com/design/downloads/index.html

First off, the facts:

if (booleanValue)

Will satisfy the if statement for any truthy value of booleanValue including true, any non-zero number, any non-empty string value, any object or array reference, etc...

On the other hand:

if (booleanValue === true)

This will only satisfy the if condition if booleanValue is exactly equal to true. No other truthy value will satisfy it.

On the other hand if you do this:

if (someVar == true)

Then, what Javascript will do is type coerce true to match the type of someVar and then compare the two variables. There are lots of situations where this is likely not what one would intend. Because of this, in most cases you want to avoid == because there's a fairly long set of rules on how Javascript will type coerce two things to be the same type and unless you understand all those rules and can anticipate everything that the JS interpreter might do when given two different types (which most JS developers cannot), you probably want to avoid == entirely.

As an example of how confusing it can be:

var x;_x000D_
_x000D_
x = 0;_x000D_
console.log(x == true);   // false, as expected_x000D_
console.log(x == false);  // true as expected_x000D_
_x000D_
x = 1;_x000D_
console.log(x == true);   // true, as expected_x000D_
console.log(x == false);  // false as expected_x000D_
_x000D_
x = 2;_x000D_
console.log(x == true);   // false, ??_x000D_
console.log(x == false);  // false 

For the value 2, you would think that 2 is a truthy value so it would compare favorably to true, but that isn't how the type coercion works. It is converting the right hand value to match the type of the left hand value so its converting true to the number 1 so it's comparing 2 == 1 which is certainly not what you likely intended.

So, buyer beware. It's likely best to avoid == in nearly all cases unless you explicitly know the types you will be comparing and know how all the possible types coercion algorithms work.

So, it really depends upon the expected values for booleanValue and how you want the code to work. If you know in advance that it's only ever going to have a true or false value, then comparing it explicitly with

if (booleanValue === true)

is just extra code and unnecessary and

if (booleanValue)

is more compact and arguably cleaner/better.

If, on the other hand, you don't know what booleanValue might be and you want to test if it is truly set to true with no other automatic type conversions allowed, then

if (booleanValue === true)

is not only a good idea, but required.

For example, if you look at the implementation of .on() in jQuery, it has an optional return value. If the callback returns false, then jQuery will automatically stop propagation of the event. In this specific case, since jQuery wants to ONLY stop propagation if false was returned, they check the return value explicity for === false because they don't want undefined or 0 or "" or anything else that will automatically type-convert to false to also satisfy the comparison.

For example, here's the jQuery event handling callback code:

ret = ( specialHandle || handleObj.handler ).apply( matched.elem, args );

if ( ret !== undefined ) {
     event.result = ret;
     if ( ret === false ) {
         event.preventDefault();
         event.stopPropagation();
     }
 }

You can see that jQuery is explicitly looking for ret === false.

But, there are also many other places in the jQuery code where a simpler check is appropriate given the desire of the code. For example:

// The DOM ready check for Internet Explorer
function doScrollCheck() {
    if ( jQuery.isReady ) {
        return;
    }
    ...

I´ve solved with this millenary technique (you can leave the Thread.Sleep on his own in the catch)

bool deleted = false;
        do
        {
            try
            {
                Directory.Delete(rutaFinal, true);                    
                deleted = true;
            }
            catch (Exception e)
            {
                string mensaje = e.Message;
                if( mensaje == "The directory is not empty.")
                Thread.Sleep(50);
            }
        } while (deleted == false);

Using is_numeric or intval is likely the best way to validate a number here, but to answer your question you could try using preg_replace instead. This example removes all non-numeric characters:

$output = preg_replace( '/[^0-9]/', '', $string );

If the string you are operating on is very long, or you are operating on many strings, then it could be worthwhile using a java.util.regex.Matcher (this requires time up-front to compile, so it won't be efficient if your input is very small or your search pattern changes frequently).

Below is a full example, based on a list of tokens taken from a map. (Uses StringUtils from Apache Commons Lang).

Map<String,String> tokens = new HashMap<String,String>();
tokens.put("cat", "Garfield");
tokens.put("beverage", "coffee");

String template = "%cat% really needs some %beverage%.";

// Create pattern of the format "%(cat|beverage)%"
String patternString = "%(" + StringUtils.join(tokens.keySet(), "|") + ")%";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(template);

StringBuffer sb = new StringBuffer();
while(matcher.find()) {
    matcher.appendReplacement(sb, tokens.get(matcher.group(1)));
}
matcher.appendTail(sb);

System.out.println(sb.toString());

Once the regular expression is compiled, scanning the input string is generally very quick (although if your regular expression is complex or involves backtracking then you would still need to benchmark in order to confirm this!)

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

db.query(
        TABLE_NAME,
        new String[] { TABLE_ROW_ID, TABLE_ROW_ONE, TABLE_ROW_TWO },
        TABLE_ROW_ID + "=" + rowID,
        null, null, null, null, null
);

TABLE_ROW_ID + "=" + rowID, here = is the where clause. To select all values you will have to give all column names:

or you can use a raw query like this 
db.rawQuery("SELECT * FROM permissions_table WHERE name = 'Comics' ", null);

and here is a good tutorial for database.

I get this post is old but there have been changes to how select2 works now and the answer to this question is extremely simple.

To set the values in a multi select2 is as follows

$('#Books_Illustrations').val([1,2,3]).change();

There is no need to specify .select2 in jquery anymore, simply .val

Also there will be times you will not want to fire the change event because you might have some other code that will execute which is what will happen if you use the method above so to get around that you can change the value without firing the change event like so

$('#Books_Illustrations').select2([1,2,3], null, false);

A little variation on classes. Initialize it with hashtables.

class Point { $x; $y }

$a = [Point[]] (@{ x=1; y=2 },@{ x=3; y=4 })

$a

x y        
- -          
1 2
3 4

$a.gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Point[]                                  System.Array

$a[0].gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     False    Point                                    System.Object

Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.

Use the subplots_adjust() function to move the bottom of the subplot up:

fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.

Then play with the offset in the legend bbox_to_anchor part of the legend command, to get the legend box where you want it. Some combination of setting the figsize and using the subplots_adjust(bottom=...) should produce a quality plot for you.

Alternative: I simply changed the line:

fig = plt.figure(1)

to:

fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')

and changed

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))

to

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))

and it shows up fine on my screen (a 24-inch CRT monitor).

Here figsize=(M,N) sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport option when including graphics.

The problem I need to solve is to store contracts containing a few fields (address, book, num_of_days, borrower_addr, blk_data), blk_data is a transaction list (block number and transaction address). This question and answer helped me. I would like to share my code as below. Hope this helps.

1. Schema definition. See blk_data.

var ContractSchema = new Schema(
    {
        address: {type: String, required: true, max: 100},  //contract address
        // book_id: {type: String, required: true, max: 100},  //book id in the book collection
        book: { type: Schema.ObjectId, ref: 'clc_books', required: true }, // Reference to the associated book.
        num_of_days: {type: Number, required: true, min: 1},
        borrower_addr: {type: String, required: true, max: 100},
        // status: {type: String, enum: ['available', 'Created', 'Locked', 'Inactive'], default:'Created'},

        blk_data: [{
            tx_addr: {type: String, max: 100}, // to do: change to a list
            block_number: {type: String, max: 100}, // to do: change to a list
        }]
    }
);

2. Create a record for the collection in the MongoDB. See blk_data.

// Post submit a smart contract proposal to borrowing a specific book.
exports.ctr_contract_propose_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('req_addr', 'req_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('new_contract_addr', 'contract_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),
    body('num_of_days', 'num_of_days must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data and old id.
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                cur_contract: req.body.new_contract_addr,
                status: 'await_approval'
            };

        async.parallel({
            //call the function get book model
            books: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if (results.books.isNew) {
                // res.render('pg_error', {
                //     title: 'Proposing a smart contract to borrow the book',
                //     c: errors.array()
                // });
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var contract = new Contract(
                {
                    address: req.body.new_contract_addr,
                    book: req.body.book_id,
                    num_of_days: req.body.num_of_days,
                    borrower_addr: req.body.req_addr

                });

            var blk_data = {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                };
            contract.blk_data.push(blk_data);

            // Data from form is valid. Save book.
            contract.save(function (err) {
                if (err) { return next(err); }
                // Successful - redirect to new book record.
                resObj = {
                    "res": contract.url
                };
                res.status(200).send(JSON.stringify(resObj));
                // res.redirect();
            });

        });

    },
];

3. Update a record. See blk_data.

// Post lender accept borrow proposal.
exports.ctr_contract_propose_accept_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('contract_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                status: 'on_loan'
            };

        // Create a contract object with escaped/trimmed data
        var contract_fields = {
            $push: {
                blk_data: {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                }
            }
        };

        async.parallel({
            //call the function get book model
            book: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
            contract: function(callback) {
                Contract.findByIdAndUpdate(req.body.contract_id, contract_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if ((results.book.isNew) || (results.contract.isNew)) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var resObj = {
                "res": results.contract.url
            };
            res.status(200).send(JSON.stringify(resObj));
        });
    },
];

There are different ways to return status code, 1 : RestController class should extends BaseRest class, in BaseRest class we can handle exception and return expected error codes. for example :

@RestController

Hope this is your structure:

    </li>
     <li>
        <div ><img.. /><p>text</p></div>
    </li>
   </ul> 

By default, it will be add one after another row:

-----
-----

if you want to make it vertical, just add float left to li, give width and height, make sure that content will not break the width:

|  |  |
|  |  |

li
{
   display:block;
   float:left;
   width:300px; /* adjust */
   height:150px; /* adjust */
   padding: 5px; /*adjust*/
}

used the following snippet and it worked fine..

.smallText .bmv-disclaimer {
   height: 40px;
}

Just adding this. In your package.json, if your "main": "index.js" is correctly set. Just use node .

{
  "name": "app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
     ...
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
     ...
  },
  "devDependencies": {
    ...
  }
}

The simplest possible solution I found was:

In your markup:

<a [href]="location.path()">Reload</a>

and in your component typescript file:

constructor(
        private location: Location
  ) { }

this looks like PHP to me. I'll delete if it's some other language.

Simply unset($arr[1]);

I've read this whole thread, and I just want to point out what seems like an inconsistency to me.

The compiler prevents you from doing the assignment with Lists:

List<Tiger> myTigersList = new List<Tiger>() { new Tiger(), new Tiger(), new Tiger() };
List<Animal> myAnimalsList = myTigersList;    // Compiler error

But the compiler is perfectly fine with arrays:

Tiger[] myTigersArray = new Tiger[3] { new Tiger(), new Tiger(), new Tiger() };
Animal[] myAnimalsArray = myTigersArray;    // No problem

The argument about whether the assignment is known to be safe falls apart here. The assignment I did with the array is not safe. To prove that, if I follow that up with this:

myAnimalsArray[1] = new Giraffe();

I get a runtime exception "ArrayTypeMismatchException". How does one explain this? If the compiler really wants to prevent me from doing something stupid, it should have prevented me from doing the array assignment.

The way i am going to tell you, will allow you to change the labels of legend, axis, title etc with a single formula and you don't need to use memorise multiple formulas. This will not affect the font style or the design of the labels/ text of titles and axis.

I am giving the complete answer of the question below.

 library(ggplot2)
 rating <- c(rnorm(200), rnorm(200, mean=.8))
 cond <-factor(rep(c("A", "B"), each = 200))
 df <- data.frame(cond,rating 
             )

 k<- ggplot(data=df, aes(x=rating, fill=cond))+ 
 geom_density(alpha = .3) +
 xlab("NEW RATING TITLE") +
 ylab("NEW DENSITY TITLE")

 # to change the cond to a different label
 k$labels$fill="New Legend Title"

 # to change the axis titles
 k$labels$y="Y Axis"
 k$labels$x="X Axis"
 k

I have stored the ggplot output in a variable "k". You can name it anything you like. Later I have used

k$labels$fill ="New Legend Title"

to change the legend. "fill" is used for those labels which shows different colours. If you have labels that shows sizes like 1 point represent 100, other point 200 etc then you can use this code like this-

k$labels$size ="Size of points"

and it will change that label title.

if you are using same date format and have select query where date in oracle :

   select count(id) from Table_name where TO_DATE(Column_date)='07-OCT-2015';

To_DATE provided by oracle

All is right but in my case i have two class like this

namespace WebAPI.Model
{
   public class ProductsModel
{ 
        [Table("products")]
        public class Products
        {
            [Key]
            public int slno { get; set; }

            public int productId { get; set; }
            public string ProductName { get; set; }

            public int Price { get; set; }
}
        }
    }

After deleting the upper class it works fine for me.

An alternative solution for preventing functions to change the user par. You can set the default parameters early on the function, so that the graphical parameters and layout will not be changed during the function execution. See ?on.exit for further details.

on.exit(layout(1))
opar<-par(no.readonly=TRUE)
on.exit(par(opar),add=TRUE,after=FALSE)

What about:

$('#play').click(function() {_x000D_
  const audio = new Audio("https://freesound.org/data/previews/501/501690_1661766-lq.mp3");_x000D_
  audio.play();_x000D_
});

Why not just use this?

var interopHelper = new WindowInteropHelper(System.Windows.Application.Current.MainWindow);
var activeScreen = Screen.FromHandle(interopHelper.Handle);

It will work on Linux kernel 2.6.28 (confirmed on 4.9.x). It won't work on FreeBSD and other Unix flavors.

Your /usr/local/bin/groovy is a shell script wrapping the Java runtime running Groovy.

Had the same problem. In my case it was my usb cord.

Your code and schema are OK. You probably trying on previous version of table.

http://sqlfiddle.com/#!2/9dc64/1/0

Your table even has no UNIQUE, so that error is impossible on that table.

Backup data from that table, drop it and re-create.

Maybe you tried to run that CREATE TABLE IF NOT EXIST. It was not created, you have old version, but there was no error because of IF NOT EXIST.

You may run SQL like this to see current table structure:

DESCRIBE my_table;

Edit - added later:

Try to run this:

DROP TABLE `my_table`; --make backup - it deletes table

CREATE TABLE `my_table` (
  `number` int(11) NOT NULL,
  `name` varchar(50) NOT NULL,
  `money` int(11) NOT NULL,
  PRIMARY KEY (`number`,`name`),
  UNIQUE (`number`, `name`) --added unique on 2 rows
) ENGINE=MyISAM;

In Microservices world (having a common shared codebase), each Microservice would have a Dockerfile whereas at the root level (generally outside of all Microservices and where your parent POM resides) you would define a docker-compose.yml to group all Microservices into a full-blown app.

In your case "Docker Compose" is preferred over "Dockerfile". Think "App" Think "Compose".

You are missing a comma in your statement.

Try this:

data[data[, "Var1"]>10, ]

Or:

data[data$Var1>10, ]

Or:

subset(data, Var1>10)

data(mtcars)

Only CSS 3 supports that,

background-size: 200px 50px;

But I would edit the image itself, so that the user needs to load less, and it might look better than a shrunken image without antialiasing.

Do not set cnopts.hostkeys = None (as the second most upvoted answer shows), unless you do not care about security. You lose a protection against Man-in-the-middle attacks by doing so.

Use CnOpts.hostkeys (returns HostKeys) to manage trusted host keys.

cnopts = pysftp.CnOpts(knownhosts='known_hosts')

with pysftp.Connection(host, username, password, cnopts=cnopts) as sftp:

where the known_hosts contains a server public key(s)] in a format like:

example.com ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...

If you do not want to use an external file, you can also use

from base64 import decodebytes
# ...

keydata = b"""AAAAB3NzaC1yc2EAAAADAQAB..."""
key = paramiko.RSAKey(data=decodebytes(keydata))
cnopts = pysftp.CnOpts()
cnopts.hostkeys.add('example.com', 'ssh-rsa', key)

with pysftp.Connection(host, username, password, cnopts=cnopts) as sftp:

Though as of pysftp 0.2.9, this approach will issue a warning, what seems like a bug:
"Failed to load HostKeys" warning while connecting to SFTP server with pysftp

An easy way to retrieve the host key in the needed format is using OpenSSH ssh-keyscan:

$ ssh-keyscan example.com
# example.com SSH-2.0-OpenSSH_5.3
example.com ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...

(due to a bug in pysftp, this does not work, if the server uses non-standard port – the entry starts with [example.com]:port + beware of redirecting ssh-keyscan to a file in PowerShell)

You can also make the application do the same automatically:
Use Paramiko AutoAddPolicy with pysftp
(It will automatically add host keys of new hosts to known_hosts, but for known host keys, it will not accept a changed key)

Though for an absolute security, you should not retrieve the host key remotely, as you cannot be sure, if you are not being attacked already.

See my article Where do I get SSH host key fingerprint to authorize the server?
It's for my WinSCP SFTP client, but most information there is valid in general.

If you need to verify the host key using its fingerprint only, see Python - pysftp / paramiko - Verify host key using its fingerprint.

A quite similar way is to use:

feature.add_argument('--feature',action='store_true')

and if you set the argument --feature in your command

 command --feature

the argument will be True, if you do not set type --feature the arguments default is always False!

There is also -l:libstatic1.a (minus l colon) variant of -l option in gcc which can be used to link static library (Thanks to https://stackoverflow.com/a/20728782). Is it documented? Not in the official documentation of gcc (which is not exact for shared libs too): https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html

-llibrary
-l library 

Search the library named library when linking. (The second alternative with the library as a separate argument is only for POSIX compliance and is not recommended.) ... The only difference between using an -l option and specifying a file name is that -l surrounds library with ‘lib’ and ‘.a’ and searches several directories.

The binutils ld doc describes it. The -lname option will do search for libname.so then for libname.a adding lib prefix and .so (if enabled at the moment) or .a suffix. But -l:name option will only search exactly for the name specified: https://sourceware.org/binutils/docs/ld/Options.html

-l namespec
--library=namespec

Add the archive or object file specified by namespec to the list of files to link. This option may be used any number of times. If namespec is of the form :filename, ld will search the library path for a file called filename, otherwise it will search the library path for a file called libnamespec.a.

On systems which support shared libraries, ld may also search for files other than libnamespec.a. Specifically, on ELF and SunOS systems, ld will search a directory for a library called libnamespec.so before searching for one called libnamespec.a. (By convention, a .so extension indicates a shared library.) Note that this behavior does not apply to :filename, which always specifies a file called filename.

The linker will search an archive only once, at the location where it is specified on the command line. If the archive defines a symbol which was undefined in some object which appeared before the archive on the command line, the linker will include the appropriate file(s) from the archive. However, an undefined symbol in an object appearing later on the command line will not cause the linker to search the archive again.

See the -( option for a way to force the linker to search archives multiple times.

You may list the same archive multiple times on the command line.

This type of archive searching is standard for Unix linkers. However, if you are using ld on AIX, note that it is different from the behaviour of the AIX linker.

The variant -l:namespec is documented since 2.18 version of binutils (2007): https://sourceware.org/binutils/docs-2.18/ld/Options.html

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.

I found Steve Hibbert's response to be very helpful. The problem the OP seemed to be describing is that of an AutoGeneratedColumns on a GridView.

In this instance you can set which columns will be "visible" and which will be hidden when you bind a data table in the code behind.

For example: A Gridview is on the page as follows.

<asp:GridView ID="gv" runat="server" AutoGenerateColumns="False" >
</asp:GridView>

And then in the code behind a PopulateGridView routine is called during the page load event.

protected void PopulateGridView()
{
    DataTable dt = GetDataSource();
    gv.DataSource = dt;
    foreach (DataColumn col in dt.Columns)
    {
        BoundField field = new BoundField();
        field.DataField = col.ColumnName;
        field.HeaderText = col.ColumnName;
        if (col.ColumnName.EndsWith("ID"))
        {
            field.Visible = false;
        }
        gv.Columns.Add(field);
    }
    gv.DataBind();
}

In the above the GridView AutoGenerateColumns is set to False and the codebehind is used to create the bound fields. One is obtaining the datasource as a datatable through one's own process which here I labeled GetDataSource(). Then one loops through the columns collection of the datatable. If the column name meets a given criteria, you can set the bound field visible property accordingly. Then you bind the data to the gridview. This is very similar to AutoGenerateColumns="True" but you get to have criteria for the columns. This approach is most useful when the criteria for hiding and un-hiding is based upon the column name.

Just discovered this one after i tried Fara's answer but it didn't work on my project. Just drag the column from the Data Sources window, and drop to the Label or TextBox.

The problem is that you're (probably) trying to plot a vector that consists exclusively of missing (NA) values. Here's an example:

> x=rep(NA,100)
> y=rnorm(100)
> plot(x,y)
Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

In your example this means that in your line plot(costs,pseudor2,type="l"), costs is completely NA. You have to figure out why this is, but that's the explanation of your error.

From comments:

Scott C Wilson: Another possible cause of this message (not in this case, but in others) is attempting to use character values as X or Y data. You can use the class function to check your x and Y values to be sure if you think this might be your issue.

stevec: Here is a quick and easy solution to that problem (basically wrap x in as.factor(x))

Java programming provides wrapper class for each primitive data types, to convert a primitive data types to correspond object of wrapper class.

Consider the following servlet conf:

   <servlet>
        <servlet-name>NewServlet</servlet-name>
        <servlet-class>NewServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>NewServlet</servlet-name>
        <url-pattern>/NewServlet/*</url-pattern>
    </servlet-mapping>

Now, when I hit the URL http://localhost:8084/JSPTemp1/NewServlet/jhi, it will invoke NewServlet as it is mapped with the pattern described above.

Here:

getRequestURI() =  /JSPTemp1/NewServlet/jhi
getPathInfo() = /jhi

We have those ones:

• getPathInfo()

  returns
  a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information

• getRequestURI()

  returns
  a String containing the part of the URL from the protocol name up to the query string

I've been battling this kind of problem for a while, and I think I've come up with a reliable solution.

It's pretty difficult to know for sure that this.getActivity() isn't going to return null for a Fragment, especially if you're dealing with any kind of network behaviour which gives your code ample time to withdraw Activity references.

In the solution below, I declare a small management class called the ActivityBuffer. Essentially, this class deals with maintaining a reliable reference to an owning Activity, and promising to execute Runnables within a valid Activity context whenever there's a valid reference available. The Runnables are scheduled for execution on the UI Thread immediately if the Context is available, otherwise execution is deferred until that Context is ready.

/** A class which maintains a list of transactions to occur when Context becomes available. */
public final class ActivityBuffer {

    /** A class which defines operations to execute once there's an available Context. */
    public interface IRunnable {
        /** Executes when there's an available Context. Ideally, will it operate immediately. */
        void run(final Activity pActivity);
    }

    /* Member Variables. */
    private       Activity        mActivity;
    private final List<IRunnable> mRunnables;

    /** Constructor. */
    public ActivityBuffer() {
        // Initialize Member Variables.
        this.mActivity  = null;
        this.mRunnables = new ArrayList<IRunnable>();
    }

    /** Executes the Runnable if there's an available Context. Otherwise, defers execution until it becomes available. */
    public final void safely(final IRunnable pRunnable) {
        // Synchronize along the current instance.
        synchronized(this) {
            // Do we have a context available?
            if(this.isContextAvailable()) {
                // Fetch the Activity.
                final Activity lActivity = this.getActivity();
                // Execute the Runnable along the Activity.
                lActivity.runOnUiThread(new Runnable() { @Override public final void run() { pRunnable.run(lActivity); } });
            }
            else {
                // Buffer the Runnable so that it's ready to receive a valid reference.
                this.getRunnables().add(pRunnable);
            }
        }
    }

    /** Called to inform the ActivityBuffer that there's an available Activity reference. */
    public final void onContextGained(final Activity pActivity) {
        // Synchronize along ourself.
        synchronized(this) {
            // Update the Activity reference.
            this.setActivity(pActivity);
            // Are there any Runnables awaiting execution?
            if(!this.getRunnables().isEmpty()) {
                // Iterate the Runnables.
                for(final IRunnable lRunnable : this.getRunnables()) {
                    // Execute the Runnable on the UI Thread.
                    pActivity.runOnUiThread(new Runnable() { @Override public final void run() {
                        // Execute the Runnable.
                        lRunnable.run(pActivity);
                    } });
                }
                // Empty the Runnables.
                this.getRunnables().clear();
            }
        }
    }

    /** Called to inform the ActivityBuffer that the Context has been lost. */
    public final void onContextLost() {
        // Synchronize along ourself.
        synchronized(this) {
            // Remove the Context reference.
            this.setActivity(null);
        }
    }

    /** Defines whether there's a safe Context available for the ActivityBuffer. */
    public final boolean isContextAvailable() {
        // Synchronize upon ourself.
        synchronized(this) {
            // Return the state of the Activity reference.
            return (this.getActivity() != null);
        }
    }

    /* Getters and Setters. */
    private final void setActivity(final Activity pActivity) {
        this.mActivity = pActivity;
    }

    private final Activity getActivity() {
        return this.mActivity;
    }

    private final List<IRunnable> getRunnables() {
        return this.mRunnables;
    }

}

In terms of its implementation, we must take care to apply the life cycle methods to coincide with the behaviour described above by Pawan M:

public class BaseFragment extends Fragment {

    /* Member Variables. */
    private ActivityBuffer mActivityBuffer;

    public BaseFragment() {
        // Implement the Parent.
        super();
        // Allocate the ActivityBuffer.
        this.mActivityBuffer = new ActivityBuffer();
    }

    @Override
    public final void onAttach(final Context pContext) {
        // Handle as usual.
        super.onAttach(pContext);
        // Is the Context an Activity?
        if(pContext instanceof Activity) {
            // Cast Accordingly.
            final Activity lActivity = (Activity)pContext;
            // Inform the ActivityBuffer.
            this.getActivityBuffer().onContextGained(lActivity);
        }
    }

    @Deprecated @Override
    public final void onAttach(final Activity pActivity) {
        // Handle as usual.
        super.onAttach(pActivity);
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextGained(pActivity);
    }

    @Override
    public final void onDetach() {
        // Handle as usual.
        super.onDetach();
        // Inform the ActivityBuffer.
        this.getActivityBuffer().onContextLost();
    }

    /* Getters. */
    public final ActivityBuffer getActivityBuffer() {
        return this.mActivityBuffer;
    }

}

Finally, in any areas within your Fragment that extends BaseFragment that you're untrustworthy about a call to getActivity(), simply make a call to this.getActivityBuffer().safely(...) and declare an ActivityBuffer.IRunnable for the task!

The contents of your void run(final Activity pActivity) are then guaranteed to execute along the UI Thread.

The ActivityBuffer can then be used as follows:

this.getActivityBuffer().safely(
  new ActivityBuffer.IRunnable() {
    @Override public final void run(final Activity pActivity) {
       // Do something with guaranteed Context.
    }
  }
);

The best way in Javascript:

if (document.getElementsByClassName("search-box").length > 0) {
// do something
}

I have difficulty in decrypting a long string that is encrypted in python. Here is the python encryption function:

def RSA_encrypt(public_key, msg, chunk_size=214):
    """
    Encrypt the message by the provided RSA public key.

    :param public_key: RSA public key in PEM format.
    :type public_key: binary

    :param chunk_size: the chunk size used for PKCS1_OAEP decryption, it is determined by \
    the private key length used in bytes - 42 bytes.
    :type chunk_size: int
    :return: Base 64 encryption of the encrypted message
    :rtype: binray
    """
    rsa_key = RSA.importKey(public_key)
    rsa_key = PKCS1_OAEP.new(rsa_key)

    encrypted = b''
    offset = 0
    end_loop = False

    while not end_loop:
        chunk = msg[offset:offset + chunk_size]

        if len(chunk) % chunk_size != 0:
            chunk += " " * (chunk_size - len(chunk))
            end_loop = True

        encrypted += rsa_key.encrypt(chunk.encode())
        offset += chunk_size

    return base64.b64encode(encrypted)

The decryption in PHP:

INT_MAX is just a definition in limits.h. You don't make it clear whether you need to store an integer or floating point value. If integer, and using a 64-bit compiler, use a LONG (LLONG for 32-bit).

<select id="selectId">
    <option value="A">A</option>
    <option value="B">B</option>
    <option value="C">C</option>
</select>


$('#selectId').on('change', function () {
     var selectVal = $("#selectId option:selected").val();
});

First create a select option. After that using jquery you can get current selected value when user change select option value.

iframes are used a lot to include complete pages. When those pages are hosted on another domain you get problems with cross side scripting and stuff. There are ways to fix this.

Frames were used to divide your page into multiple parts (for example, a navigation menu on the left). Using them is no longer recommended.

According to pip documentation at

http://pip.readthedocs.org/en/stable/user_guide/#configuration

You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows

On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini

The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob

On linux the $HOME directory can be located by using cd ~

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\Bob\Desktop

Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path

After saving the command would then be

pip install pandas

However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.

 h1 { font-size: 150%; }
 h2 { font-size: 120%; }

Tune as needed.

This seems to work:

select your_column  
from your_table  
order by   
case when isnumeric(your_column) = 1 then your_column else 999999999 end,  
your_column   

For me, these steps fixed the issue:

1- Running this cmd as admin:

npm install --global --production windows-build-tools

2- Then running npm rebuild after the 1st step is completed (especially completing the python 2.7 installation, which was the main cause of the issue)

1. You need an appropriate permission in manifest.xml:

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

2. out.flush() check the out is not null..

3. String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + 
                               "/PhysicsSketchpad";
   File dir = new File(file_path);
   if(!dir.exists())
       dir.mkdirs();
   File file = new File(dir, "sketchpad" + pad.t_id + ".png");
   FileOutputStream fOut = new FileOutputStream(file);
   
   bmp.compress(Bitmap.CompressFormat.PNG, 85, fOut);
   fOut.flush();
   fOut.close();
   

Quoting

AMD:

• One browser-first approach
• Opting for asynchronous behavior and simplified backwards compatibility
• It doesn't have any concept of File I/O.
• It supports objects, functions, constructors, strings, JSON and many other types of modules.

CommonJS:

• One server-first approach
• Assuming synchronous behavior
• Cover a broader set of concerns such as I/O, File system, Promises and more.
• Supports unwrapped modules, it can feel a little more close to the ES.next/Harmony specifications, freeing you of the define() wrapper that AMD enforces.
• Only support objects as modules.

A nicer option is to make the display of console.log and debugger statements conditional based on the node environment.

  rules: {
    // allow console and debugger in development
    'no-console': process.env.NODE_ENV === 'production' ? 2 : 0,
    'no-debugger': process.env.NODE_ENV === 'production' ? 2 : 0,
  },

Assuming you want to get columns 1 and 9 with that code snippet, it should be:

extractedData = data[:,[1,9]]

An option for your application would be to write a replacement Home Screen using the android.intent.category.HOME Intent. I believe this type of Intent you can see the home button.

More details:

http://developer.android.com/guide/topics/intents/intents-filters.html#imatch

you can do this in different ways:

1. Setting a timeout in the web service caller from code (not 100% sure but I think I have seen this done);
2. Setting a timeout in the constructor of the web service proxy in the web references;
3. Setting a timeout in the server side, web.config of the web service application.

see here for more details on the second case:

http://msdn.microsoft.com/en-us/library/ff647786.aspx#scalenetchapt10_topic14

and here for details on the last case:

How to increase the timeout to a web service request?

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

Note that datalist is not the same as a select. It allows users to enter a custom value that is not in the list, and it would be impossible to fetch an alternate value for such input without defining it first.

Possible ways to handle user input are to submit the entered value as is, submit a blank value, or prevent submitting. This answer handles only the first two options.

If you want to disallow user input entirely, maybe select would be a better choice.

To show only the text value of the option in the dropdown, we use the inner text for it and leave out the value attribute. The actual value that we want to send along is stored in a custom data-value attribute:

To submit this data-value we have to use an <input type="hidden">. In this case we leave out the name="answer" on the regular input and move it to the hidden copy.

<input list="suggestionList" id="answerInput">
<datalist id="suggestionList">
    <option data-value="42">The answer</option>
</datalist>
<input type="hidden" name="answer" id="answerInput-hidden">

This way, when the text in the original input changes we can use javascript to check if the text also present in the datalist and fetch its data-value. That value is inserted into the hidden input and submitted.

document.querySelector('input[list]').addEventListener('input', function(e) {
    var input = e.target,
        list = input.getAttribute('list'),
        options = document.querySelectorAll('#' + list + ' option'),
        hiddenInput = document.getElementById(input.getAttribute('id') + '-hidden'),
        inputValue = input.value;

    hiddenInput.value = inputValue;

    for(var i = 0; i < options.length; i++) {
        var option = options[i];

        if(option.innerText === inputValue) {
            hiddenInput.value = option.getAttribute('data-value');
            break;
        }
    }
});

The id answer and answer-hidden on the regular and hidden input are needed for the script to know which input belongs to which hidden version. This way it's possible to have multiple inputs on the same page with one or more datalists providing suggestions.

Any user input is submitted as is. To submit an empty value when the user input is not present in the datalist, change hiddenInput.value = inputValue to hiddenInput.value = ""

Working jsFiddle examples: plain javascript and jQuery

You cannot echo an array. Must use print_r instead.

<?php
$result = $conn->query("Select * from tbl");
$row = $result->fetch_assoc();
print_r ($row);
?>

use this code

echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';

The problem was:

1. you missed "
2. It should be alert not alery

Refer this:

@RequestMapping(value="download", method=RequestMethod.GET)
public void getDownload(HttpServletResponse response) {

// Get your file stream from wherever.
InputStream myStream = someClass.returnFile();

// Set the content type and attachment header.
response.addHeader("Content-disposition", "attachment;filename=myfilename.txt");
response.setContentType("txt/plain");

// Copy the stream to the response's output stream.
IOUtils.copy(myStream, response.getOutputStream());
response.flushBuffer();
}

Drop root privileges after you bind to port 80 (or 443).

This allows port 80/443 to remain protected, while still preventing you from serving requests as root:

function drop_root() {
    process.setgid('nobody');
    process.setuid('nobody');
}

A full working example using the above function:

var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
    res.write("Success!");
    res.end();
});

server.listen(80, null, null, function() {
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
    drop_root();
    console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

Before messing with Nginx config, try to disable ChromePHP first.

1 - Open app/config/config_dev.yml

2 - Comment these lines:

chromephp:
    type:   chromephp
    level:  info

ChromePHP pack the debug info json-encoded in the X-ChromePhp-Data header, which is too big for the default config of nginx with fastcgi.

I'm surprised nobody mentioned diff -y to produce a side-by-side output, for example:

diff -y file1 file2 > file3

And in file3(different lines have a symbol | in middle):

same     same
diff_1 | diff_2
