I found good answer here Adding Role dynamically in new VS 2013 Identity UserManager

But in case to provide an example so you can check it I am gonna share some default code.

First make sure you have Roles inserted.

And second test it on user register method.

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = new ApplicationUser() { UserName = model.UserName  };

        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded)
        {
            var currentUser = UserManager.FindByName(user.UserName); 

            var roleresult = UserManager.AddToRole(currentUser.Id, "Superusers");

            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("Index", "Home");
        }
        else
        {
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

And finally you have to get "Superusers" from the Roles Dropdown List somehow.

public class JSElementLocator {

    @Test
    public void locateElement() throws InterruptedException{
        WebDriver driver = WebDriverProducerFactory.getWebDriver("firefox");

        driver.get("https://www.google.co.in/");


        WebElement searchbox = null;

        Thread.sleep(1000);
        searchbox = (WebElement) (((JavascriptExecutor) driver).executeScript("return document.getElementById('lst-ib');", searchbox));
        searchbox.sendKeys("hello");
    }
}

Make sure you are using the right locator for it.

You aren't ever writing anything to do with the data you read in. Do you want to be adding the data structure in feeds to the new one you're creating?

Or perhaps you want to open the file in append mode open(filename, 'a') and then add your string, by writing the string produced by json.dumps instead of using json.dump - but nneonneo points out that this would be invalid json.

The smallest unit you can work with is a byte (which is of char type). You can work with bits though by using bitwise operators.

As for integer literals, you can only work with decimal (base 10), octal (base 8) or hexadecimal (base 16) numbers. There are no binary (base 2) literals in C nor C++.

Octal numbers are prefixed with 0 and hexadecimal numbers are prefixed with 0x. Decimal numbers have no prefix.

In C++0x you'll be able to do what you want by the way via user defined literals.

Install without the need for sudo

If you want to install pip without the need for sudo, which is always frustrating when trying to install packages globally, install pip in your local folder /usr/local like this:

curl https://bootstrap.pypa.io/get-pip.py > get-pip.py
python get-pip.py --prefix=/usr/local/

and then:

pip install <package-of-choice> without sudo

@Drewid's answer didn't work in my Firefox 25 if the flash plugin is just disabled but installed.

@invertedSpear's comment in that answer worked in firefox but not in any IE version.

So combined both their code and got this. Tested in Google Chrome 31, Firefox 25, IE 8-10. Thanks Drewid and invertedSpear :)

var hasFlash = false;
try {
  var fo = new ActiveXObject('ShockwaveFlash.ShockwaveFlash');
  if (fo) {
    hasFlash = true;
  }
} catch (e) {
  if (navigator.mimeTypes
        && navigator.mimeTypes['application/x-shockwave-flash'] != undefined
        && navigator.mimeTypes['application/x-shockwave-flash'].enabledPlugin) {
    hasFlash = true;
  }
}

The second one:

word.contains("\n");

This seems to work for me.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            DropDownList1.DataBind(); // get the data into the list you can set it
            DropDownList1.Items.FindByValue("SOMECREDITPROBLEMS").Selected = true;
        }
    }

Position:fixed gives an absolute position regarding the BROWSER window. so of course it goes there.

While position:absolute refers to the parent element, so if you place your <div> button inside the <div> of the container, it should position where you meant it to be. Something like

EDIT: thanks to @Sotiris, who has a point, solution can be achieved using a position:fixed and a margin-left. Like this: http://jsfiddle.net/NeK4k/

You can double click directly on the .cs file representing your form in the Solution Explorer :

This will open Form1.cs [Design], which contains the drag&drop controls.

If you are directly in the code behind (The file named Form1.cs, without "[Design]"), you can press Shift + F7 (or only F7 depending on the project type) instead to open it.

From the design view, you can switch back to the Code Behind by pressing F7.

You can use a list comprehension:

def search(name, people):
    return [element for element in people if element['name'] == name]

A compact implementation using Java TreeMap and recursion:

import java.util.TreeMap;

public class RomanNumber {

    private final static TreeMap<Integer, String> map = new TreeMap<Integer, String>();

    static {

        map.put(1000, "M");
        map.put(900, "CM");
        map.put(500, "D");
        map.put(400, "CD");
        map.put(100, "C");
        map.put(90, "XC");
        map.put(50, "L");
        map.put(40, "XL");
        map.put(10, "X");
        map.put(9, "IX");
        map.put(5, "V");
        map.put(4, "IV");
        map.put(1, "I");

    }

    public final static String toRoman(int number) {
        int l =  map.floorKey(number);
        if ( number == l ) {
            return map.get(number);
        }
        return map.get(l) + toRoman(number-l);
    }

}

Testing:

public void testRomanConversion() {

    for (int i = 1; i<= 100; i++) {
        System.out.println(i+"\t =\t "+RomanNumber.toRoman(i));
    }

}

Using Jupyterthemes, one can easily change look of notebook.

pip install jupyterthemes

jt -fs 15 

By default code font size is set to 11 . Trying above will change font size. It can be reset using.

jt -r 

This will reset all jupyter theme changes to default.

Activate MySQL general.log (disk intensive) and use mysql_analyse_general_log.pl to extract long running transactions, for example with :

--min-duration=your innodb_lock_wait_timeout value

Disable general.log after that.

Here is very good answer of your question

see the example mentioned on above MSDN page :-

If you need to read all values from a section in properties file in a simple manner:

Your config.cfg file layout :

[SECTION_NAME]  
key1 = value1  
key2 = value2  

You code:

   import configparser

   config = configparser.RawConfigParser()
   config.read('path_to_config.cfg file')
    
   details_dict = dict(config.items('SECTION_NAME'))

This will give you a dictionary where keys are same as in config file and their corresponding values.

details_dict is :

{'key1':'value1', 'key2':'value2'}

Now to get key1's value : details_dict['key1']

Putting it all in a method which reads sections from config file only once(the first time the method is called during a program run).

def get_config_dict():
    if not hasattr(get_config_dict, 'config_dict'):
        get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
    return get_config_dict.config_dict

Now call the above function and get the required key's value :

config_details = get_config_dict()
key_1_value = config_details['key1'] 

Generic Multi Section approach:

[SECTION_NAME_1]  
key1 = value1  
key2 = value2  

[SECTION_NAME_2]  
key1 = value1  
key2 = value2

Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.

def get_config_section():
    if not hasattr(get_config_section, 'section_dict'):
        get_config_section.section_dict = collections.defaultdict()
        
        for section in config.sections():
            get_config_section.section_dict[section] = dict(config.items(section))
    
    return get_config_section.section_dict

To access:

config_dict = get_config_section()

port = config_dict['DB']['port'] 

(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)

I found that even after following all the steps above, I was still getting errors saying that my Maven dependencies (i.e. pom.xml) were pointing to jar files that didn't exist.

Viewing the errors in the Problems tab, for some reason these were still pointing to the old location of my repository. This was probably because I'd changed the location of my Maven repository since creating the workspace and project.

This can be easily solved by deleting the project from the Eclipse workspace, and re-adding it again through Package Explorer -> R/Click -> Import... -> Existing Projects.

Nested classes are very useful for implementing internal details that should not be exposed. If you use Reflector to check classes like Dictionary<Tkey,TValue> or Hashtable you'll find some examples.

You can use XmlDocument. Also some XPath can be useful.

Just a simple example

XmlDocument doc = new XmlDocument();
doc.Load("sample.xml");
XmlElement root = doc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("some_node"); // You can also use XPath here
foreach (XmlNode node in nodes)
{
   // use node variable here for your beeds
}

if (typeof console == "undefined") {
  this.console = {
    log: function() {},
    info: function() {},
    error: function() {},
    warn: function() {}
  };
}

test.matches() method checks all text.use test.find()

Geocoding is the process of converting addresses (like "1600 Amphitheatre Parkway, Mountain View, CA") into geographic coordinates (like latitude 37.423021 and longitude -122.083739), which you can use to place markers or position the map.

Would this be what you are looking for: Contains sample code

I use cx_Freeze. Works with Python 2 and 3, and I have tested it to work on Windows, Mac, and Linux.

cx_Freeze: http://cx-freeze.sourceforge.net/

It's better to use a semi-transparent .png.

Just open Photoshop, create a 2x2 pixel image (picking 1x1 can cause an Internet Explorer bug!), fill it with a green color and set the opacity in "Layers tab" to 60%. Then save it and make it a background image:

<p style="background: url(green.png);">any text</p>

It works cool, of course, except in lovely Internet Explorer 6. There are better fixes available, but here's a quick hack:

p {
    _filter: expression((runtimeStyle.backgroundImage != 'none') ? runtimeStyle.filter = 'progid:DXImageTransform.Microsoft.AlphaImageLoader(src='+currentStyle.backgroundImage.split('\"')[1]+', sizingMethod=scale)' : runtimeStyle.filter,runtimeStyle.backgroundImage = 'none');
}

Try this:

Edit or create the file :nodesource.list

sudo gedit /etc/apt/sources.list.d/nodesource.list

Insert this text:

deb https://deb.nodesource.com/node_10.x bionic main

deb-src https://deb.nodesource.com/node_10.x bionic main

Run these commands:

curl -s https://deb.nodesource.com/gpgkey/nodesource.gpg.key | apt-key add -


sudo sh -c "echo deb https://deb.nodesource.com/node_10.x cosmic main /etc/apt/sources.list.d/nodesource.list"

sudo apt-get update

sudo apt-get install nodejs

For those of you interested in PySpark version (actually it's same in Scala - see comment below) :

    merchants_df_renamed = merchants_df.toDF(
        'merchant_id', 'category', 'subcategory', 'merchant')

    merchants_df_renamed.printSchema()

Result:

root
|-- merchant_id: integer (nullable = true)
|-- category: string (nullable = true)
|-- subcategory: string (nullable = true)
|-- merchant: string (nullable = true)

You can check if the array is empty by retrieving total elements count using JScript's VBArray() object (works with arrays of variant type, single or multidimensional):

Sub Test()

    Dim a() As Variant
    Dim b As Variant
    Dim c As Long

    ' Uninitialized array of variant
    ' MsgBox UBound(a) ' gives 'Subscript out of range' error
    MsgBox GetElementsCount(a) ' 0

    ' Variant containing an empty array
    b = Array()
    MsgBox GetElementsCount(b) ' 0

    ' Any other types, eg Long or not Variant type arrays
    MsgBox GetElementsCount(c) ' -1

End Sub

Function GetElementsCount(aSample) As Long

    Static oHtmlfile As Object ' instantiate once

    If oHtmlfile Is Nothing Then
        Set oHtmlfile = CreateObject("htmlfile")
        oHtmlfile.parentWindow.execScript ("function arrlength(arr) {try {return (new VBArray(arr)).toArray().length} catch(e) {return -1}}"), "jscript"
    End If
    GetElementsCount = oHtmlfile.parentWindow.arrlength(aSample)

End Function

For me it takes about 0.3 mksec for each element + 15 msec initialization, so the array of 10M elements takes about 3 sec. The same functionality could be implemented via ScriptControl ActiveX (it is not available in 64-bit MS Office versions, so you can use workaround like this).

Stopwatch measures time elapsed.

// Create new stopwatch
Stopwatch stopwatch = new Stopwatch();

// Begin timing
stopwatch.Start();

Threading.Thread.Sleep(500)

// Stop timing
stopwatch.Stop();

Console.WriteLine("Time elapsed: {0}", stopwatch.Elapsed);

Here is a DEMO.

If you want more control, you might want to check the TextPaint class. Here is how to use it:

final ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(final View textView) {
        //Your onClick code here
    }

    @Override
    public void updateDrawState(final TextPaint textPaint) {
        textPaint.setColor(yourContext.getResources().getColor(R.color.orange));
        textPaint.setUnderlineText(true);
    }
};

Once I also had a busy script which was occupied for hours without showing any progress. So I implemented a function which mainly includes the techniques of the previous answers:

#!/bin/bash
# Updates the progress bar
# Parameters: 1. Percentage value
update_progress_bar()
{
  if [ $# -eq 1 ];
  then
    if [[ $1 == [0-9]* ]];
    then
      if [ $1 -ge 0 ];
      then
        if [ $1 -le 100 ];
        then
          local val=$1
          local max=100

          echo -n "["

          for j in $(seq $max);
          do
            if [ $j -lt $val ];
            then
              echo -n "="
            else
              if [ $j -eq $max ];
              then
                echo -n "]"
              else
                echo -n "."
              fi
            fi
          done

          echo -ne " "$val"%\r"

          if [ $val -eq $max ];
          then
            echo ""
          fi
        fi
      fi
    fi
  fi
}

update_progress_bar 0
# Further (time intensive) actions and progress bar updates
update_progress_bar 100

import re
regex = re.compile("u'2022'",re.UNICODE)
newstring = re.sub(regex, something, yourstring, <optional flags>)

I solve with this:

Startup.cs

public void ConfigureServices(IServiceCollection services)
    {
        services.AddHttpClient("HttpClientWithSSLUntrusted").ConfigurePrimaryHttpMessageHandler(() => new HttpClientHandler
        {
            ClientCertificateOptions = ClientCertificateOption.Manual,
            ServerCertificateCustomValidationCallback =
            (httpRequestMessage, cert, cetChain, policyErrors) =>
            {
                return true;
            }
        });

YourService.cs

public UserService(IHttpClientFactory clientFactory, IOptions<AppSettings> appSettings)
    {
        _appSettings = appSettings.Value;
        _clientFactory = clientFactory;
    }

var request = new HttpRequestMessage(...

var client = _clientFactory.CreateClient("HttpClientWithSSLUntrusted");

HttpResponseMessage response = await client.SendAsync(request);

A slightly less ugly version of the same thing mentioned in pretty much all these answers:

UIViewController *rootViewController = [[self.navigationController viewControllers] firstObject];

in your case, I'd probably do something like:

inside your UINavigationController subclass:

- (UIViewController *)rootViewController
{
    return [[self viewControllers] firstObject];
}

then you can use:

UIViewController *rootViewController = [self.navigationController rootViewController];

edit

OP asked for a property in the comments.

if you like, you can access this via something like self.navigationController.rootViewController by just adding a readonly property to your header:

@property (nonatomic, readonly, weak) UIViewController *rootViewController;

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

Tables are iffy (at least, in IE) when it comes to fixing heights and not wrapping text. I think you'll find that the only solution is to put the text inside a div element, like so:

td.container > div {_x000D_
    width: 100%;_x000D_
    height: 100%;_x000D_
    overflow:hidden;_x000D_
}_x000D_
td.container {_x000D_
    height: 20px;_x000D_
}

<table>_x000D_
    <tr>_x000D_
        <td class="container">_x000D_
            <div>This is a long line of text designed not to wrap _x000D_
                 when the container becomes too small.</div>_x000D_
        </td>_x000D_
    </tr>_x000D_
</table>

This way, the div's height is that of the containing cell and the text cannot grow the div, keeping the cell/row the same height no matter what the window size is.

An update on @Scott T.'s answer: the interface between Resource Server and Authorization Server for token validation was standardized in IETF RFC 7662 in October 2015, see: https://tools.ietf.org/html/rfc7662. A sample validation call would look like:

POST /introspect HTTP/1.1
Host: server.example.com
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer 23410913-abewfq.123483

token=2YotnFZFEjr1zCsicMWpAA

and a sample response:

HTTP/1.1 200 OK
Content-Type: application/json

{
  "active": true,
  "client_id": "l238j323ds-23ij4",
  "username": "jdoe",
  "scope": "read write dolphin",

  "exp": 1419356238,
  "iat": 1419350238,
  "extension_field": "twenty-seven"
}

Of course adoption by vendors and products will have to happen over time.

In my case, I modified hibernate-core source code, well, to introduce a new annotation @DefaultValue:

Well, this is a hibernate-only solution.

if you want to execute ENABLE TRIGGER Directly From Source :

we can't write like this:

Conn.Execute "ENABLE TRIGGER trigger_name ON table_name"

instead, we can write :

Conn.Execute "ALTER TABLE table_name DISABLE TRIGGER trigger_name"

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

I ran across the same issue, this solution did the trick and was very readable:

var sentence = "This., -/ is #! an $ % ^ & * example ;: {} of a = -_ string with `~)() punctuation";
var newSen = sentence.match(/[^_\W]+/g).join(' ');
console.log(newSen);

Result:

"This is an example of a string with punctuation"

The trick was to create a negated set. This means that it matches anything that is not within the set i.e. [^abc] - not a, b or c

\W is any non-word, so [^\W]+ will negate anything that is not a word char.

By adding in the _ (underscore) you can negate that as well.

Make it apply globally /g, then you can run any string through it and clear out the punctuation:

/[^_\W]+/g

Nice and clean ;)

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

You can use:

EQU - equal

NEQ - not equal

LSS - less than

LEQ - less than or equal

GTR - greater than

GEQ - greater than or equal

AVOID USING:

() ! ~ - * / % + - << >> & | = *= /= %= += -= &= ^= |= <<= >>=

If you guys still interested, here is my workaround based on Guzzle middleware feature:

1. Create JsonAwaraResponse that will decode JSON response by Content-Type HTTP header, if not - it will act as standard Guzzle Response:

   <?php
   
   namespace GuzzleHttp\Psr7;
   
   
   class JsonAwareResponse extends Response
   {
       /**
        * Cache for performance
        * @var array
        */
       private $json;
   
       public function getBody()
       {
           if ($this->json) {
               return $this->json;
           }
           // get parent Body stream
           $body = parent::getBody();
   
           // if JSON HTTP header detected - then decode
           if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
               return $this->json = \json_decode($body, true);
           }
           return $body;
       }
   }
   

2. Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:

   <?php
   
   $client = new \GuzzleHttp\Client();
   
   /** @var HandlerStack $handler */
   $handler = $client->getConfig('handler');
   $handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
       return new \GuzzleHttp\Psr7\JsonAwareResponse(
           $response->getStatusCode(),
           $response->getHeaders(),
           $response->getBody(),
           $response->getProtocolVersion(),
           $response->getReasonPhrase()
       );
   }), 'json_decode_middleware');
   

After this to retrieve JSON as PHP native array use Guzzle as always:

$jsonArray = $client->get('http://httpbin.org/headers')->getBody();

Tested with guzzlehttp/guzzle 6.3.3

I use a JavaScript port of the Mersenne Twister: https://gist.github.com/300494 It allows you to set the seed manually. Also, as mentioned in other answers, the Mersenne Twister is a really good PRNG.

Try this, it must be work, otherwise you need to print the error to specify your problem

$username = $_POST['username'];
$password = $_POST['password'];

$sql = "SELECT * from Users WHERE UserName LIKE '$username'";
$result = mysql_query($sql,$con);

while($row = mysql_fetch_array($result))
{
    echo $row['FirstName'];
}

An object oriented solution:

class String
  def capitalize_first_char
    self.sub(/^(.)/) { $1.capitalize }
  end
end

Then you can just do this:

"i'm from New York".capitalize_first_char

Unfortunately, it's not completely portable. It's usually integral, but it can be any "integer or real-floating type".

You should use the StringFormat on the Binding. You can use either standard string formats, or custom string formats:

<TextBox Text="{Binding Value, StringFormat=N2}" />
<TextBox Text="{Binding Value, StringFormat={}{0:#,#.00}}" />

Note that the StringFormat only works when the target property is of type string. If you are trying to set something like a Content property (typeof(object)), you will need to use a custom StringFormatConverter (like here), and pass your format string as the ConverterParameter.

Edit for updated question

So, if your ViewModel defines the precision, I'd recommend doing this as a MultiBinding, and creating your own IMultiValueConverter. This is pretty annoying in practice, to go from a simple binding to one that needs to be expanded out to a MultiBinding, but if the precision isn't known at compile time, this is pretty much all you can do. Your IMultiValueConverter would need to take the value, and the precision, and output the formatted string. You'd be able to do this using String.Format.

However, for things like a ContentControl, you can much more easily do this with a Style:

<Style TargetType="{x:Type ContentControl}">
    <Setter Property="ContentStringFormat" 
            Value="{Binding Resolution, StringFormat=N{0}}" />
</Style>

Any control that exposes a ContentStringFormat can be used like this. Unfortunately, TextBox doesn't have anything like that.

include popper.js before bootstrap.min.js

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.0.4/popper.js"></script>

use this link to get popper

The best use would be

echo $_SERVER['HTTP_HOST'];

And it can be used like this:

if (strpos($_SERVER['HTTP_HOST'], 'banana.com') !== false) {
    echo "Yes this is indeed the banana.com domain";
}

This code below is a good way to see all the variables in $_SERVER in a structured HTML output with your keywords highlighted that halts directly after execution. Since I do sometimes forget which one to use myself - I think this can be nifty.

<?php
    // Change banana.com to the domain you were looking for..
    $wordToHighlight = "banana.com";
    $serverVarHighlighted = str_replace( $wordToHighlight, '<span style=\'background-color:#883399; color: #FFFFFF;\'>'. $wordToHighlight .'</span>',  $_SERVER );
    echo "<pre>";
    print_r($serverVarHighlighted);
    echo "</pre>";
    exit();
?>

In c++11, you can use some function like that:

int maxAt(std::vector<int>& vector_name) {
    int max = INT_MIN;
    for (auto val : vector_name) {
         if (max < val) max = val;
    }
    return max;
}

To install Docker for Mac with homebrew:

brew cask install docker

To install the command line completion:

brew install bash-completion
brew install docker-completion
brew install docker-compose-completion
brew install docker-machine-completion

You can use something like this

("{:0%db}"%length).format(num)

64/32 bit error? I found this as a problem as my dev machine was 32bit and the production server 64bit. If so, you may need to call the 32bit runtime directly from the command line.

VisualVm does not come with Apple JDK. You can use VisualVM Mac Application bundle(dmg) as a separate application, to compensate for that.

If you just want the two branches 'email' and 'staging' to be the same, you can tag the 'email' branch, then reset the 'email' branch to the 'staging' one:

$ git checkout email
$ git tag old-email-branch
$ git reset --hard staging

You can also rebase the 'staging' branch on the 'email' branch. But the result will contains the modification of the two branches.

Reflector and its add-in FileDisassembler.

Reflector will allow to see the source code. FileDisassembler will allow you to convert it into a VS solution.

Directly calling a URL to get an image may concern with major security issues. You need to ensure that you have sufficient rights to access that resource. However You can use ByteOutputStream to read image file. This is an example (Its just an example, you need to do necessary changes as per your requirement.)

ByteArrayOutputStream bis = new ByteArrayOutputStream();
InputStream is = null;
try {
  is = url.openStream ();
  byte[] bytebuff = new byte[4096]; 
  int n;

  while ( (n = is.read(bytebuff)) > 0 ) {
    bis.write(bytebuff, 0, n);
  }
}

Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:

import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()

nm -g list the extern variable, which is not necessary exported symbol. Any non-static file scope variable(in C) are all extern variable.

nm -D will list the symbol in the dynamic table, which you can find it's address by dlsym.

GNU nm 2.17.50.0.6-12.el5 20061020

On Mac OS for IntelliJ v12, shut down the IDE, and then you can execute:

rm -rf ~/Library/Preferences/IdeaIC12/*

Restart the IDE, or open a pom.xml of your choosing. You will be asked whether you want to import the preferences from an existing IntelliJ instance. Select the "No, I do not have a previous IntelliJ version" radio button.

For me, it was because I had deleted the hidden .git folder.

I fixed it by deleting the folder, re-cloning, and re-making the changes.

There is a big difference between postfix and prefix versions of ++.

In the prefix version (i.e., ++i), the value of i is incremented, and the value of the expression is the new value of i.

In the postfix version (i.e., i++), the value of i is incremented, but the value of the expression is the original value of i.

Let's analyze the following code line by line:

int i = 10;   // (1)
int j = ++i;  // (2)
int k = i++;  // (3)

1. i is set to 10 (easy).
2. Two things on this line:
   • i is incremented to 11.
   • The new value of i is copied into j. So j now equals 11.
3. Two things on this line as well:
   • i is incremented to 12.
   • The original value of i (which is 11) is copied into k. So k now equals 11.

So after running the code, i will be 12 but both j and k will be 11.

The same stuff holds for postfix and prefix versions of --.

Method canOpenUrl is in iOS 9 (due to privacy) changed and is not free to use any more. Your banner provider checks for installed apps so that they do not show banners for an app that is already installed.

That gives all the log statements like

-canOpenURL: failed for URL: "kindle://home" - error: "This app is not allowed to query for scheme kindle"

The providers should update their logic for this.

If you need to query for installed apps/available schemes you need to add them to your info.plist file.

Add the key 'LSApplicationQueriesSchemes' to your plist as an array. Then add strings in that array like 'kindle'.

Of course this is not really an option for the banner ads (since those are dynamic), but you can still query that way for your own apps or specific other apps like Twitter and Facebook.

I experienced the same issue as the OP - Wordpress keeps redirecting to install-php after migration.

Problem was my database tables are named as prefix_tablename and I missed the underscore from $table_prefix in wp-config.

$table_prefix = 'myprefix';

should have been

$table_prefix = 'myprefix_';

The following creates a generic function, taking an array of any size and of any type by reference:

template<typename T, std::size_t S>
void my_func(T (&arr)[S]) {
   // do stuff
}

play with the code.

Looking at the code below, I tried it and found: Instead of writing DBCon = DBConnection.Instance(); you should put DBConnection DBCon - new DBConnection(); (That worked for me)

and instead of MySqlComman cmd = new MySqlComman(query, DBCon.GetConnection()); you should put MySqlCommand cmd = new MySqlCommand(query, DBCon.GetConnection()); (it's missing the d)

GUI-based IDEs like Visual Studio and Eclipse have several advantages over text-based IDEs like Emacs or vim because of their display capabilities:

• WYSIWYG preview and live editing for GUI design
• Efficient property editors (eg. color selection using a GUI palette, including positioning gradient stops etc)
• Graphical depiction of code outlines, file interrelationships, etc
• More efficient use of screen real-estate to show breakpoints, bookmarks, errors, etc
• Better drag and drop support with OS and other applications
• Integrated editing of drawings, images, 3D models, etc
• Display and edit of database models

Basically with a GUI-based IDE you can get more useful information on screen at once and you can view/edit graphical portions of of your application as easily as text portions.

One of the coolest things to experience as a developer is editing a method that computes some data and seeing the live output of your code displayed graphically in another window, just as your user will see it when you run the app. Now that's WYSIWYG editing!

Text-based IDEs like Emacs and vim can add features like code completion and refactoring over time, so in the long run their main limitation is their text-based display model.

Try this instead

SELECT MAX(shoppername), COUNT(*) AS cnt
FROM dbo.sales
GROUP BY CHECKSUM(*)
HAVING COUNT(*) > 1

Read about the CHECKSUM function first, as there can be duplicates.

My problem: I forgot to import a newly added project (added by my co-worker) into my eclipse workspace.

File > Import > Maven > Existing Maven Projects, find it in the dir-tree, check the single non-ghosted one which is not already added.

Details: My co-worker had added a new project which was a git submodule. Existing projects referred to it in their pom.xml. I had already done "git submodule init" and "git submodule update". mvn built fine from the command-line but I kept getting this "Missing artifact" error in eclipse pointing at the top of my pom.xml.

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

There're no packets in TCP API.

There're packets in underlying protocols often, like when TCP is done over IP, which you have no interest in, because they have nothing to do with the user except for very delicate performance optimizations which you are probably not interested in (according to the question's formulation).

If you ask what is a maximum number of bytes you can send() in one API call, then this is implementation and settings dependent. You would usually call send() for chunks of up to several kilobytes, and be always ready for the system to refuse to accept it totally or partially, in which case you will have to manually manage splitting into smaller chunks to feed your data into the TCP send() API.

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false). To add an extra column with only the non-reimbursed amounts, you would use something like:

=IF(B1="No", A1, 0)

and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.

Use String.split

"0000000020C90037:TEMP:data".split(':')

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

30 10,14 * * *

To answer the first part of your question: Microsoft published their Entity Framework version history here.

The easiest way to do it is to link the CSV-file into the Access database as a table. Then you can work on this table as if it was an ordinary access table, for instance by creating an appropriate query based on this table that returns exactly what you want.

You can link the table either manually or with VBA like this

DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true

UPDATE

Dim db As DAO.Database

' Re-link the CSV Table
Set db = CurrentDb
On Error Resume Next:   db.TableDefs.Delete "tblImport":   On Error GoTo 0
db.TableDefs.Refresh
DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true
db.TableDefs.Refresh

' Perform the import
db.Execute "INSERT INTO someTable SELECT col1, col2, ... FROM tblImport " _
   & "WHERE NOT F1 IN ('A1', 'A2', 'A3')"
db.Close:   Set db = Nothing

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

The following line can be used if we want to specify the relative path of the file.

File file = new File("./properties/files/ListStopWords.txt");  

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

Just in case you arrived here because you copied a branch name from Github, note that a remote branch is not automatically also a local branch, so a merge will not work and give the "not something we can merge" error.

In that case, you have two options:

git checkout [branchYouWantToMergeInto]
git merge origin/[branchYouWantToMerge]

or

# this creates a local branch
git checkout [branchYouWantToMerge]

git checkout [branchYouWantToMergeInto]
git merge [branchYouWantToMerge]

It is now this For swift 3,

    let button = (sender as AnyObject)
    button.setTitle("Your text", for: .normal)

(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :

    (sender as AnyObject).setTitle("Your text", for: .normal)

Remember this is used inside the IBAction of your button.

With inspiration from the Bob's answer, these extensions also support null value conversion and all primitive conversion back and fourth.

public static class ConversionExtensions
{
        public static object Convert(this object value, Type t)
        {
            Type underlyingType = Nullable.GetUnderlyingType(t);

            if (underlyingType != null && value == null)
            {
                return null;
            }
            Type basetype = underlyingType == null ? t : underlyingType;
            return System.Convert.ChangeType(value, basetype);
        }

        public static T Convert<T>(this object value)
        {
            return (T)value.Convert(typeof(T));
        }
}

Examples

            string stringValue = null;
            int? intResult = stringValue.Convert<int?>();

            int? intValue = null;
            var strResult = intValue.Convert<string>();

If you want to set image as background for whole page, use this:

body
{
    background-image: url('Image URL');
}

You can use my plugin waitForImages to handle this...

$(document).waitForImages(function() {
   // Loaded.
});

The advantage of this is you can localise it to one ancestor element and it can optionally detect images referenced in the CSS.

This is just the tip of the iceberg though, check the documentation for more functionality.

Dictionary<T1, Tuple<T2, T3>>

Edit: Sorry - I forgot you don't get Tuples until .NET 4.0 comes out. D'oh!

If you have a wamp setup that won't send emails, there is only a couple of things to do. 1. find out what the smtp server name is for your isp. The gmail thing is most likely unnecessary complication 2. create a phpsetup.php file in your 'www' folder and edit like this:

<?php
   phpinfo();
?>

this will give you a handle on what wamp is using. 3. search for the php.ini file. there may be serveral. The one you want is the one that effects the output of the file above. 4. find the smtp address in the most likely php.ini. 5. Type in your browser localhost/phpsetup.php and scroll down to smtp setting. it should say 'localhost' 6. edit the php.ini file smtp setting to the name of your ISPs smtp server. check if it changes for you phpsetup.php. if it works your done, if not you are working the wrong file.

this issue should be on the Wordpress site but they are way too up-them-selves or trying to get clients.;)

By default, the below code will NOT generate a checked Check Box as model properties override the html attributes:

@Html.CheckBoxFor(m => m.SomeBooleanProperty, new { @checked = "checked" });

Instead, in your GET Action method, the following needs to be done:

model.SomeBooleanProperty = true;

The above will preserve your selection(If you uncheck the box) even if model is not valid(i.e. some error occurs on posting the form).

However, the following code will certainly generate a checked checkbox, but will not preserve your uncheck responses, instead make the checkbox checked every time on errors in form.

 @Html.CheckBox("SomeBooleanProperty", new { @checked = "checked" });

UPDATE

//Get Method
   public ActionResult CreateUser(int id)
   {
        model.SomeBooleanProperty = true;         
   }

Above code would generate a checked check Box at starting and will also preserve your selection even on errors in form.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

Method 1 (Preferred) - Using hMailServer

After installation, you need the following configuration to properly send mail from wampserver:

1) When you first open hMailServer Administrator, you need to add a new domain.
2) Click on the "Add Domain ..." button at the Welcome page. 
3) Under the domain text field, enter your computer's IP, in this case it should be 127.0.0.1.
4) Click on the Save button.
5) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
6) Enter "localhost" in the localhost name field.
7) Click on the Save button.

If you need to send mail using a FROM addressee of another computer, you need to allow deliveries from External to External accounts. To do that, follow these steps:

1) Go to Settings>Advanced>IP Ranges and double click on "My Computer" which should have IP address of 127.0.0.1
2) Check the Allow Deliveries from External to External accounts checkbox.
3) Save settings using Save button.

(However, Windows Live/Hotmail has denied all emails coming from dynamic IPs, which most residential computers are using. The workaround is to use Gmail account )

Note to use Gmail users :

1) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
2) Enter "smtp.gmail.com" in the Remote Host name field.
3) Enter "465" as the port number
4) Check "Server requires authentication"
5) Enter gmail address in the Username
6) Enter gmail password in the password 
7) Check "Use SSL"

(Note, From field doesnt function with gmail)
*p.s. For some people it might also be needed to untick everything under require SMTP authentication in :

• for local : Settings>Advanced>IP Ranges>"My Computer"
  
• for external : Settings>Advanced>IP Ranges>"Internet"

Method 2 - Using SendMail

You can use SendMail installation.

Method 3 - Using different methods

Use any of these methods.

Use the iconv command.

To make sure the file is in Windows-1252, open it in Notepad (under Windows), then click Save As. Notepad suggests current encoding as the default; if it's Windows-1252 (or any 1-byte codepage, for that matter), it would say "ANSI".

declare @sql1 nvarchar(max) 
SELECT @sql1 =
  STUFF(
         (
           select ' drop table dbo.[' + name + ']'

           FROM sys.sysobjects AS sobjects
           WHERE (xtype = 'U') AND (name LIKE 'GROUP_BASE_NEW_WORK_%')
           for xml path('')
        ),
     1, 1, '')

  execute sp_executesql @sql1

This is how I did a similar thing. I have tiles that are thumbnails to YouTube videos. When I click the tile, it redirects me to a 'player' page that uses the 'video_id' to render the correct video to the page.

<GridTile
  key={video_id}
  title={video_title}
  containerElement={<Link to={`/player/${video_id}`}/>}
 >

ETA: Sorry, just noticed that you didn't want to use the LINK or REDIRECT components for some reason. Maybe my answer will still help in some way. ; )

I spent a while messing around with this problem, because no solution I found actually worked, strangely enough! The working directory is frequently not the directory of the JAR, especially if a JAR (or any program, for that matter) is run from the Start Menu under Windows. So here is what I did, and it works for .class files run from outside a JAR just as well as it works for a JAR. (I only tested it under Windows 7.)

try {
    //Attempt to get the path of the actual JAR file, because the working directory is frequently not where the file is.
    //Example: file:/D:/all/Java/TitanWaterworks/TitanWaterworks-en.jar!/TitanWaterworks.class
    //Another example: /D:/all/Java/TitanWaterworks/TitanWaterworks.class
    PROGRAM_DIRECTORY = getClass().getClassLoader().getResource("TitanWaterworks.class").getPath(); // Gets the path of the class or jar.

    //Find the last ! and cut it off at that location. If this isn't being run from a jar, there is no !, so it'll cause an exception, which is fine.
    try {
        PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('!'));
    } catch (Exception e) { }

    //Find the last / and cut it off at that location.
    PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(0, PROGRAM_DIRECTORY.lastIndexOf('/') + 1);
    //If it starts with /, cut it off.
    if (PROGRAM_DIRECTORY.startsWith("/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(1, PROGRAM_DIRECTORY.length());
    //If it starts with file:/, cut that off, too.
    if (PROGRAM_DIRECTORY.startsWith("file:/")) PROGRAM_DIRECTORY = PROGRAM_DIRECTORY.substring(6, PROGRAM_DIRECTORY.length());
} catch (Exception e) {
    PROGRAM_DIRECTORY = ""; //Current working directory instead.
}

Just happened to me after upgrading to Android Studio 3.1. The Offline Work checkbox was unchecked, so no luck there.

I went to Settings > Build, Execution, Deployment > Compiler and the Command-line Options textfield contained --offline, so I just deleted that and everything worked.

You can't use a function to insert data into a base table. Functions return data. This is listed as the very first limitation in the documentation:

User-defined functions cannot be used to perform actions that modify the database state.

"Modify the database state" includes changing any data in the database (though a table variable is an obvious exception the OP wouldn't have cared about 3 years ago - this table variable only lives for the duration of the function call and does not affect the underlying tables in any way).

You should be using a stored procedure, not a function.

The following works for me:

function decodeHtml(html) {
    let areaElement = document.createElement("textarea");
    areaElement.innerHTML = html;

    return areaElement.value;
}

itertools provides the chain function for that:

From http://docs.python.org/library/itertools.html#recipes:

def flatten(listOfLists):
    "Flatten one level of nesting"
    return chain.from_iterable(listOfLists)

Note that the result is an iterable, so you may need list(flatten(...)).

What about using ternary operator?

<?php
 // Example usage for: Ternary Operator
 $action = (empty($_POST['action'])) ? 'default' : $_POST['action'];
?>

Which is identical to this if/else statement:

<?php
 if (empty($_POST['action'])) {
   $action = 'default';
 } else {
   $action = $_POST['action'];
 }
?>

This will work even when there are multiple instance of jar is running

All the other answers are great, but I find it best to understand them by breaking down files into three categories: unstaged, staged, commit:

• --hard should be easy to understand, it restores everything
• --mixed (default) :
  1. unstaged files: don't change
  2. staged files: move to unstaged
  3. commit files: move to unstaged
• --soft:
  1. unstaged files: don't change
  2. staged files: dont' change
  3. commit files: move to staged

In summary:

• --soft option will move everything (except unstaged files) into staging area
• --mixed option will move everything into unstaged area

Add the following in the config file, and it will be caught in try catch block. Word of caution... try to avoid this situation, as this means some kind of violation is happening.

   </runtime>
</configuration>

The Swiss Army knife of image lazy loading is YUI's ImageLoader.

Because there is more to this problem than simply watching the scroll position.

The main issue that is mentioned by others but not called out enough is that -O3 does nothing at all in Swift (and never has) so when compiled with that it is effectively non-optimised (-Onone).

Option names have changed over time so some other answers have obsolete flags for the build options. Correct current options (Swift 2.2) are:

-Onone // Debug - slow
-O     // Optimised
-O -whole-module-optimization //Optimised across files

Whole module optimisation has a slower compile but can optimise across files within the module i.e. within each framework and within the actual application code but not between them. You should use this for anything performance critical)

You can also disable safety checks for even more speed but with all assertions and preconditions not just disabled but optimised on the basis that they are correct. If you ever hit an assertion this means that you are into undefined behaviour. Use with extreme caution and only if you determine that the speed boost is worthwhile for you (by testing). If you do find it valuable for some code I recommend separating that code into a separate framework and only disabling the safety checks for that module.

strikes  = [number_map[int(x)] for x in input_str.split()]

Use square brackets to explore dictionaries.

What about simply

    if (condition) { code if condition = true };

If all you want to do is run your Python Script on a windows computer that has the Python Interpreter installed, converting the extension of your saved script from '.py' to '.pyw' should do the trick.

But if you're using py2exe to convert your script into a standalone application that would run on any windows machine, you will need to make the following changes to your 'setup.py' file.

The following example is of a simple python-GUI made using Tkinter:

from distutils.core import setup
import py2exe
setup (console = ['tkinter_example.pyw'],
       options = { 'py2exe' : {'packages':['Tkinter']}})

Change "console" in the code above to "windows"..

from distutils.core import setup
import py2exe
setup (windows = ['tkinter_example.pyw'],
       options = { 'py2exe' : {'packages':['Tkinter']}})

This will only open the Tkinter generated GUI and no console window.

My opinion is that the best for PHP is RadPHP.

I had faced the similar error, it is basically caused when use the ad blockers.Turn them off, and you run it easily.

I am on Windows 10 but same version of Anaconda.

1. Click on the Start Menu, then All Programs (just Programs for Win10)
2. Click on the Anaconda3 folder; mine is Anaconda3 (64-bit)
3. In there you should see Jupyter Notebook. If you have a virtual environment installed, it will be followed by the environment name like this: Jupyter Notebook (env)
4. Right-click Jupyter Notebook entry and navigate to More => Open File Location
5. Right-click the correct Jupyter Notebook entry, then click on Properties
6. Enter a path in the Start in: box; if the path has spaces in it, you must enclose it in double quotes
7. Delete "%USERPROFILE%" at the end of the executable path

Note: If your app targets API level 26 or higher, the system imposes restrictions on using or creating background services unless the app itself is in the foreground.

If an app needs to create a foreground service, the app should call startForegroundService(). That method creates a background service, but the method signals to the system that the service will promote itself to the foreground.

Once the service has been created, the service must call its startForeground() method within five seconds.

Both or and || evaluate to true if either operand is true. They evaluate their second operand only if the first is false.

As with and, the only difference between or and || is their precedence.

Just to make life interesting, and and or have the same precedence, while && has a higher precedence than ||.

A straightforward way to do this with no extra tools is to export the registry to a text file before the install, then export it to another file after. Then, compare the two files.

Having said that, the Sysinternals tools are great for this.

I'd say the minimum would be to

• know one of the .Net Languages (C#, VB.NET, etc.)
• know the basic working of the .Net runtime
• know and understand the core parts of the .Net class libraries
• have an understanding about what additional classes and functions are available as part of the .Net class libraries

I like Andy's answer, but the id isn't going to necessarily be unique, so here's what I came up with to create a unique ID also. Can be checked at jsfiddle too. Please note that arr.length + 1 may very well not guarantee a unique ID if anything had been removed previously.

var array = [ { id: 1, username: 'fred' }, { id: 2, username: 'bill' }, { id: 3, username: 'ted' } ];
var usedname = 'bill';
var newname = 'sam';

// don't add used name
console.log('before usedname: ' + JSON.stringify(array));
tryAdd(usedname, array);
console.log('before newname: ' + JSON.stringify(array));
tryAdd(newname, array);
console.log('after newname: ' + JSON.stringify(array));

function tryAdd(name, array) {
    var found = false;
    var i = 0;
    var maxId = 1;
    for (i in array) {
        // Check max id
        if (maxId <= array[i].id)
            maxId = array[i].id + 1;

        // Don't need to add if we find it
        if (array[i].username === name)
            found = true;
    }

    if (!found)
        array[++i] = { id: maxId, username: name };
}

new mongoose.Schema({ description: { type: String, required: true, trim: true }, completed: { type: Boolean, default: false }, owner: { type: mongoose.Schema.Types.ObjectId, required: true, ref: 'User' } }, { timestamps: true });

There is no one built-in function in C++ to do this. If you'd like to replace all instances of one substring with another, you can do so by intermixing calls to string::find and string::replace. For example:

size_t index = 0;
while (true) {
     /* Locate the substring to replace. */
     index = str.find("abc", index);
     if (index == std::string::npos) break;

     /* Make the replacement. */
     str.replace(index, 3, "def");

     /* Advance index forward so the next iteration doesn't pick it up as well. */
     index += 3;
}

In the last line of this code, I've incremented index by the length of the string that's been inserted into the string. In this particular example - replacing "abc" with "def" - this is not actually necessary. However, in a more general setting, it is important to skip over the string that's just been replaced. For example, if you want to replace "abc" with "abcabc", without skipping over the newly-replaced string segment, this code would continuously replace parts of the newly-replaced strings until memory was exhausted. Independently, it might be slightly faster to skip past those new characters anyway, since doing so saves some time and effort by the string::find function.

Hope this helps!

I found a simple way to do this on EightForums (Option 8), create a string value under HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers. Set the name to the path to the program and the value to ~RUNASDMIN. Next time you open the program it will open as an administrator

[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
    "C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\Common7\\IDE\\devenv.exe"="~RUNASADMIN"

I would recommend using the postMessage API.

In your iframe, call:

window.parent.postMessage({message: 'Hello world'}, 'http://localhost/');

In the page you're including the iframe you can listen for events like this:

window.addEventListener('message', function(event) {
      if(event.origin === 'http://localhost/')
      {
        alert('Received message: ' + event.data.message);
      }
      else
      {
        alert('Origin not allowed!');
      }

    }, false);

By the way, it is also possible to do calls to other windows, and not only iframes.

Read more about the postMessage API on John Resigs blog here

I think most people who answered are a bit clueless and have found a solution by trial and error. I too had this issue recently and looked at the various solutions in this thread and they did not make much sense. I looked in to my project's makefile (it is handmade by my project lead) and I found -j11 in there. I replaced that with -j1 and it fixed the problem. The hunch was that make was probably doing a bad job at running multiple jobs (threads) i.e. while one thread was working on a file, another thread was trying to use it.

For those who use an IDE to compile your code, you need to look for a build property where you can set the number of jobs and then try compiling your code with the number of jobs set to 1. You might also have to close and restart the IDE (it all depends on how the IDEs are programmed).

I understand that this might hinder the performance of your builds but there is probably no alternative to this until either make fixes this bug (if there is one, I haven't bothered to dig in) or the makefile generators become smart enough to prevent this situation.

ApplicationPoolIdentity is actually the best practice to use in IIS7+. It is a dynamically created, unprivileged account. To add file system security for a particular application pool see IIS.net's "Application Pool Identities". The quick version:

If the application pool is named "DefaultAppPool" (just replace this text below if it is named differently)

1. Open Windows Explorer
2. Select a file or directory.
3. Right click the file and select "Properties"
4. Select the "Security" tab
5. Click the "Edit" and then "Add" button
6. Click the "Locations" button and make sure you select the local machine. (Not the Windows domain if the server belongs to one.)
7. Enter "IIS AppPool\DefaultAppPool" in the "Enter the object names to select:" text box. (Don't forget to change "DefaultAppPool" here to whatever you named your application pool.)
8. Click the "Check Names" button and click "OK".

To get request.form as a normal dictionary , use request.form.to_dict(flat=False).

To return JSON data for an API, pass it to jsonify.

This example returns form data as JSON data.

@app.route('/form_to_json', methods=['POST'])
def form_to_json():
    data = request.form.to_dict(flat=False)
    return jsonify(data)

Here's an example of POST form data with curl, returning as JSON:

$ curl http://127.0.0.1:5000/data -d "name=ivanleoncz&role=Software Developer"
{
  "name": "ivanleoncz", 
  "role": "Software Developer"
}

I had this same issue now and found that my sub-projects 'Public Header Folder Path' was set to an incorrect path (when compared with what my main project was using as its 'Header Search Path' and 'User Header Search Path').

e.g.

My main project had the following:

• Header Search Paths
  • Debug "build/Debug-iphoneos/../../Headers"
  • Release "build/Debug-iphoneos/../../Headers"

And the same for the User Header Search Paths

Whereas my sub-project (dependency) had the following:

• Public Header Folder Path
  • Debug "include/BoxSDK"
  • Release "include/BoxSDK"

Changing the 'Public Header Folder Path' to "../../Headers/BoxSDK" fixed the problem since the main project was already searching that folder ('../../Headers').

As a programming noob, I found a bunch of the above answers overly complex, especially if the goal is to have a simple function that you can pass various yes/no questions to, forcing the user to select yes or no. After scouring this page and several others, and borrowing all of the various good ideas, I ended up with the following:

def yes_no(question_to_be_answered):
    while True:
        choice = input(question_to_be_answered).lower()
        if choice[:1] == 'y': 
            return True
        elif choice[:1] == 'n':
            return False
        else:
            print("Please respond with 'Yes' or 'No'\n")

#See it in Practice below 

musical_taste = yes_no('Do you like Pine Coladas?')
if musical_taste == True:
    print('and getting caught in the rain')
elif musical_taste == False:
    print('You clearly have no taste in music')

Make sure you log into psql as the owner of the tables. to find out who own the tables use \dt

psql -h CONNECTION_STRING DBNAME -U OWNER_OF_THE_TABLES

then you can run the GRANTS

Just to add another option to the mix, there are several useful constants within the string module. While more useful in other cases, they can be used here.

>>> from string import digits
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'

There are several constants in the module, including:

• ascii_letters (abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
• hexdigits (0123456789abcdefABCDEF)

If you are using these constants heavily, it can be worthwhile to covert them to a frozenset. That enables O(1) lookups, rather than O(n), where n is the length of the constant for the original strings.

>>> digits = frozenset(digits)
>>> ''.join(c for c in "abc123def456" if c in digits)
'123456'

If you are using the Python wrappers, then (assuming your matrix name is mat):

• mat.shape gives you an array of the type- [height, width, channels]

• mat.size gives you the size of the array

Sample Code:

import cv2
mat = cv2.imread('sample.png')
height, width, channel = mat.shape[:3]
size = mat.size

I had the same problem for a long time now, I often needed to mix Matchers and values and I never managed to do that with Mockito.... until recently ! I put the solution here hoping it will help someone even if this post is quite old.

It is clearly not possible to use Matchers AND values together in Mockito, but what if there was a Matcher accepting to compare a variable ? That would solve the problem... and in fact there is : eq

when(recommendedAccessor.searchRecommendedHolidaysProduct(eq(metas), any(List.class), any(HotelsBoardBasisType.class), any(Config.class)))
            .thenReturn(recommendedResults);

In this example 'metas' is an existing list of values

In my case, I modified directory tag.

From

<Directory "D:/Devel/matysart/matysart_dev1">
  Allow from all
  Order Deny,Allow
</Directory>

To

<Directory "D:/Devel/matysart/matysart_dev1">
  Require local
</Directory>

And it seriously worked. It's seems changed with Apache 2.4.2.

exclude module: 'support-v4'

Would not work for me with a project dependency, the only way I could get it to work was via the following syntax:

configurations {
    dependencies {
        compile(project(':Android-SDK')) {
            compile.exclude module: 'support-v4'
        }
    }
}

Where :Android-SDK is your project name.

Another way (depending on your actual needs): If you want to pop the first n characters and save both the popped characters and the modified string:

s = 'lipsum'
n = 3
a, s = s[:n], s[n:]
print(a)
# lip
print(s)
# sum

this is the easiest way: Make list
Select list
right click: Define Name (e.g. ItemStatus)
select a cell where the list should appear (copy paste can be done later, so not location critical)
Data > Data Validation
Allow: Select List
Source: =ItemStatus (don't forget the = sign)
click Ok
dropdown appears in the cell you selected
Home > Conditional Formatting
Manage Rules
New Rule
etc.

ul {
margin:0;
list-style-type: none;
}
li:before { content: "- ";}

First, learn the core concepts of Node.js:

• You'll want to understand the asynchronous coding style that Node.js encourages.

• Async != concurrent. Understand Node.js's event loop!

• Node.js uses CommonJS-style require() for code loading; it's probably a bit different from what you're used to.

• Familiarize yourself with Node.js's standard library.

Then, you're going to want to see what the community has to offer:

The gold standard for Node.js package management is NPM.

• It is a command line tool for managing your project's dependencies.

• Make sure you understand how Node.js and NPM interact with your project via the node_modules folder and package.json.

• NPM is also a registry of pretty much every Node.js package out there

Finally, you're going to want to know what some of the more popular packages are for various tasks:

Useful Tools for Every Project:

• Underscore contains just about every core utility method you want.
• Lo-Dash is a clone of Underscore that aims to be faster, more customizable, and has quite a few functions that underscore doesn't have. Certain versions of it can be used as drop-in replacements of underscore.
• TypeScript makes JavaScript considerably more bearable, while also keeping you out of trouble!
• JSHint is a code-checking tool that'll save you loads of time finding stupid errors. Find a plugin for your text editor that will automatically run it on your code.

Unit Testing:

• Mocha is a popular test framework.
• Vows is a fantastic take on asynchronous testing, albeit somewhat stale.
• Expresso is a more traditional unit testing framework.
• node-unit is another relatively traditional unit testing framework.
• AVA is a new test runner with Babel built-in and runs tests concurrently.

Web Frameworks:

• Express.js is by far the most popular framework.
• Koa is a new web framework designed by the team behind Express.js, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs.
• sails.js the most popular MVC framework for Node.js, and is based on express. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture.
• Meteor bundles together jQuery, Handlebars, Node.js, WebSocket, MongoDB, and DDP and promotes convention over configuration without being a Ruby on Rails clone.
• Tower (deprecated) is an abstraction of a top of Express.js that aims to be a Ruby on Rails clone.
• Geddy is another take on web frameworks.
• RailwayJS is a Ruby on Rails inspired MVC web framework.
• Sleek.js is a simple web framework, built upon Express.js.
• Hapi is a configuration-centric framework with built-in support for input validation, caching, authentication, etc.

• Trails is a modern web application framework. It builds on the pedigree of Rails and Grails to accelerate development by adhering to a straightforward, convention-based, API-driven design philosophy.

• Danf is a full-stack OOP framework providing many features in order to produce a scalable, maintainable, testable and performant applications and allowing to code the same way on both the server (Node.js) and client (browser) sides.

• Derbyjs is a reactive full-stack JavaScript framework. They are using patterns like reactive programming and isomorphic JavaScript for a long time.

• Loopback.io is a powerful Node.js framework for creating APIs and easily connecting to backend data sources. It has an Angular.js SDK and provides SDKs for iOS and Android.

Web Framework Tools:

• Jade is the HAML/Slim of the Node.js world
• EJS is a more traditional templating language.
• Don't forget about Underscore's template method!

Networking:

• Connect is the Rack or WSGI of the Node.js world.
• Request is a very popular HTTP request library.
• socket.io is handy for building WebSocket servers.

Command Line Interaction:

• minimist just command line argument parsing.
• Yargs is a powerful library for parsing command-line arguments.
• Commander.js is a complete solution for building single-use command-line applications.
• Vorpal.js is a framework for building mature, immersive command-line applications.
• Chalk makes your CLI output pretty.

Code Generators:

• Yeoman Scaffolding tool from the command-line.
• Skaffolder Code generator with visual and command-line interface. It generates a customizable CRUD application starting from the database schema or an OpenAPI 3.0 YAML file.

Work with streams:

• mississipi everything you miss about streams.
• https://github.com/calvinmetcalf/streams-a-love-story
• http://maxogden.com/node-streams.html
• https://github.com/substack/stream-handbook
• How streams help to raise Node.js performance

You can also harness the __new__ method to your advantage. You just forgot something. The __new__ method always returns the new object so you must return its superclass' new method. Do as follows.

class F:
    def __new__(cls):
        if cls is F:
            raise TypeError("Cannot create an instance of abstract class '{}'".format(cls.__name__))
        return super().__new__(cls)

When using the new method, you have to return the object, not the None keyword. That's all you missed.

You put them in the workspace/projects folder. You should put them directly in the workspace folder and then do an Import Existing Projects into workspace.

there are better ways to do it as mentioned on android developer sites http://developer.android.com/guide/topics/location/strategies.html

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

After setting the JAVA_HOME variable, run android studio as administrator

In Razor (.cshtml) you can do:

@{
    var isDisabled = true;
}

<a href="@(isDisabled ? "#" : @Url.Action("Index", "Home"))" @(isDisabled ? "disabled=disabled" : "") class="btn btn-default btn-lg btn-block">Home</a>

According to the documentation you need to specify the key store:

Protocol authhttps = new Protocol("https",  
      new AuthSSLProtocolSocketFactory(
          new URL("file:my.keystore"), "mypassword",
          new URL("file:my.truststore"), "mypassword"), 443); 

 HttpClient client = new HttpClient();
 client.getHostConfiguration().setHost("localhost", 443, authhttps);

I've found the same problem. I lost almost a day trying to start a service from OnClickListener method - outside the onCreate and after 1 day, I still failed!!!! Very frustrating! I was looking at the sample example RemoteServiceController. Theirs works, but my implementation does not work!

The only way that was working for me, was from inside onCreate method. None of the other variants worked and believe me I've tried them all.

Conclusion:

• If you put your service class in different package than the mainActivity, I'll get all kind of errors

• Also the one "/" couldn't find path to the service, tried starting with Intent(package,className) and nothing , also other type of Intent starting

• I moved the service class in the same package of the activity Final form that works

• Hopefully this helps someone by defining the listerners onClick inside the onCreate method like this:

  public void onCreate() {
  //some code......
      Button btnStartSrv  = (Button)findViewById(R.id.btnStartService);
      Button btnStopSrv  = (Button)findViewById(R.id.btnStopService);
  
      btnStartSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              startService(new Intent("RM_SRV_AIDL"));
          }
      });
  
      btnStopSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              stopService(new Intent("RM_SRV_AIDL"));
          }
      });
  
  } // end onCreate
  

Also very important for the Manifest file, be sure that service is child of application:

<application ... >
    <activity ... >
     ...
    </activity>
    <service
        android:name="com.mainActivity.MyRemoteGPSService"
        android:label="GPSService"
        android:process=":remote">

        <intent-filter>
             <action android:name="RM_SRV_AIDL" />
        </intent-filter>
    </service>
</application>

To make the change for one session, use this command:

:set tabstop=4

To make the change permanent, add it to ~/.vimrc or ~/.vim/vimrc:

set tabstop=4

This will affect all files, not just css. To only affect css files:

autocmd Filetype css setlocal tabstop=4

as stated in Michal's answer.

3.1 didn't matter for me.

It took me a while, but I managed to find the 2.1 release to try that out here: http://www.oracle.com/technetwork/testcontent/index21-ea1-095147.html

1.2 http://www.oracle.com/technetwork/testcontent/index-archive12-101280.html

That doesn't work either though, still no tables so it looks like something with permission.

You can use mplayer.

mencoder -nocache -rtsp-stream-over-tcp rtsp://192.168.XXX.XXX/test.sdp -oac copy -ovc copy -o test.avi

The "copy" codec is just a dumb copy of the stream. Mencoder adds a header and stuff you probably want.

In the mplayer source file "stream/stream_rtsp.c" is a prebuffer_size setting of 640k and no option to change the size other then recompile. The result is that writing the stream is always delayed, which can be annoying for things like cameras, but besides this, you get an output file, and can play it back most places without a problem.

In many workflows where you want to attach a default / initial value for arbitrary keys, you don't need to hash each key individually ahead of time. You can use collections.defaultdict. For example:

from collections import defaultdict

d = defaultdict(lambda: None)

print(d[1])  # None
print(d[2])  # None
print(d[3])  # None

This is more efficient, it saves having to hash all your keys at instantiation. Moreover, defaultdict is a subclass of dict, so there's usually no need to convert back to a regular dictionary.

For workflows where you require controls on permissible keys, you can use dict.fromkeys as per the accepted answer:

d = dict.fromkeys([1, 2, 3, 4])

First backup the old database called HRMS and edit the script file with replace the word HRMS to SUNHRM. After this step import the database file to the mysql

just add this code:

this.$forceUpdate()

As answered but to save typing out "2006-01-02T15:04:05.000Z" for the layout, you could use the package's constant RFC3339.

str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(time.RFC3339, str)

if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

After a certain amount of time, your access token expires.

To prevent this, you can request the 'offline_access' permission during the authentication, as noted here: Do Facebook Oauth 2.0 Access Tokens Expire?

Use localStorage for that. It's persistent over sessions.

Writing :

localStorage['myKey'] = 'somestring'; // only strings

Reading :

var myVar = localStorage['myKey'] || 'defaultValue';

If you need to store complex structures, you might serialize them in JSON. For example :

Reading :

var stored = localStorage['myKey'];
if (stored) myVar = JSON.parse(stored);
else myVar = {a:'test', b: [1, 2, 3]};

Writing :

localStorage['myKey'] = JSON.stringify(myVar);

Note that you may use more than one key. They'll all be retrieved by all pages on the same domain.

Unless you want to be compatible with IE7, you have no reason to use the obsolete and small cookies.

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.

A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.

By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!

If only the incoming stream stalls for more than a millisecond you are running into a timeout.

UPDATE [GS] INNER JOIN [Views] ON

    [GS].[Name] = [Views].[Name], 
    [GS].Hostname = [Views].Hostname, 
    [GS].[Date] = [Views].[Date], 
    [GS].[Unit] = [Views].[Unit], 
    [GS].[Owner] = [Views].[Owner];

I have a slightly different way of doing this than the accepted answer. This way you can avoid using GROUP_CONCAT which has a limit of 1024 characters and will not work if you have a lot of fields.

SET @sql = '';
SELECT
    @sql := CONCAT(@sql,if(@sql='','',', '),temp.output)
FROM
(
    SELECT
      DISTINCT
        CONCAT(
         'MAX(IF(pa.fieldname = ''',
          fieldname,
          ''', pa.fieldvalue, NULL)) AS ',
          fieldname
        ) as output
    FROM
        product_additional
) as temp;

SET @sql = CONCAT('SELECT p.id
                    , p.name
                    , p.description, ', @sql, ' 
                   FROM product p
                   LEFT JOIN product_additional AS pa 
                    ON p.id = pa.id
                   GROUP BY p.id');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

As an extension to what have been proposed by Nico Coallier (apply to multiple columns) and U10-Forward(using apply style of methods), and summarising it into a one-liner I propose:

df.loc[:,['col1','col2']].transform(lambda x: x.map(lambda x: {1: "A", 2: "B"}.get(x,x))

The .transform() processes each column as a series. Contrary to .apply()which passes the columns aggregated in a DataFrame.

Consequently you can apply the Series method map().

Finally, and I discovered this behaviour thanks to U10, you can use the whole Series in the .get() expression. Unless I have misunderstood its behaviour and it processes sequentially the series instead of bitwisely.
The .get(x,x)accounts for the values you did not mention in your mapping dictionary which would be considered as Nan otherwise by the .map() method

Original:

I understand the current answer but needed a more clear example. Here is an example of what I used with an Adapter(RecyclerView.Adapter) and an Activity.

In your Activity:

This will implement the interface that we have in our Adapter. In this example, it will be called when the user clicks on an item in the RecyclerView.

public class MyActivity extends Activity implements AdapterCallback {

    private MyAdapter myAdapter;

    @Override
    public void onMethodCallback() {
       // do something
    }

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        myAdapter = new MyAdapter(this);
    }
}

In your Adapter:

In the Activity, we initiated our Adapter and passed this as an argument to the constructer. This will initiate our interface for our callback method. You can see that we use our callback method for user clicks.

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {

    private AdapterCallback adapterCallback;

    public MyAdapter(Context context) {
        try {
            adapterCallback = ((AdapterCallback) context);
        } catch (ClassCastException e) {
            throw new ClassCastException("Activity must implement AdapterCallback.", e);
        }
    }

    @Override
    public void onBindViewHolder(MyAdapter.ViewHolder viewHolder, int position) {
        // simple example, call interface here
        // not complete
        viewHolder.itemView.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                try {
                    adapterCallback.onMethodCallback();
                } catch (ClassCastException e) {
                   // do something
                }
            }
        });
    }

    public static interface AdapterCallback {
        void onMethodCallback();
    }
}

I have struggled to get a query to return fields from Table 1 that do not exist in Table 2 and tried most of the answers above until I found a very simple way to obtain the results that I wanted.

I set the join properties between table 1 and table 2 to the third setting (3) (All fields from Table 1 and only those records from Table 2 where the joined fields are equal) and placed a Is Null in the criteria field of the query in Table 2 in the field that I was testing for. It works perfectly.

Thanks to all above though.

To rename a table you can use:

RENAME mytable TO othertable;

or

ALTER TABLE mytable RENAME TO othertable;

or, if owned by another schema:

ALTER TABLE owner.mytable RENAME TO othertable;

Interestingly, ALTER VIEW does not support renaming a view. You can, however:

RENAME myview TO otherview;

The RENAME command works for tables, views, sequences and private synonyms, for your own schema only.

If the view is not in your schema, you can recompile the view with the new name and then drop the old view.

(tested in Oracle 10g)

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

i didn't find who made elegant answer , that's why let me say :

Array.from(
   document.querySelectorAll('#txt1,#txt2')
).map(e => parseInt(e.value) || 0) // to avoid NaN
.reduce((a, b) => a+b, 0)

window.sum= () => _x000D_
 document.getElementById('result').innerHTML=    _x000D_
   Array.from(_x000D_
     document.querySelectorAll('#txt1,#txt2')_x000D_
   ).map(e=>parseInt(e.value)||0)_x000D_
   .reduce((a,b)=>a+b,0)

<input type="text" id="txt1" onkeyup="sum()"/>_x000D_
<input type="text" id="txt2" onkeyup="sum()"  style="margin-right:10px;"/><span id="result"></span>

FIX FOR MYSQL IN DOCKER

I'm using @fefe's excellent answer here to show how to fix this problem within some minutes when using docker (via docker-compose). It's quite easy as you don't have to touch MySQL's configuration files, but it requires you to export and import your entire data:

The default situation of your MySQL setup probably looks like this. Your data is saved inside the data-mysql volume.

mysql:
  image: mysql:5.7.25
  container_name: mysql
  restart: always
  volumes:
    - data-mysql:/var/lib/mysql
  environment:
    - "MYSQL_DATABASE=XXX"
    - "MYSQL_USER=XXX"
    - "MYSQL_PASSWORD=XXX"
    - "MYSQL_ROOT_PASSWORD=XXX"
  expose:
    - 3306

1. Make a backup of your entire data/database via SQL export, so you have a .sql.gz or something. I'm using Adminer for this.

2. To fix (and as explained in @fefe's answer) we have to setup the MySQL instance from zero, meaning we have to delete the mysql docker container and the mysql volume docker container. Do a docker container ls and a docker volume ls to see all your containers and volumes, and pick the two names that are your mysql instance and your mysql volume, for me it's mysql (container) and docker_data-mysql (volume).

3. Stop your running instances via docker-compose down (or however you usually stop your docker stuff).

4. To delete them, I do docker container rm mysql and docker volume rm docker_data-mysql (note that there is an underscore AND a dash in the name).

5. Add these settings to your mysql block in your docker setup:

mysql:
  image: mysql:5.7.25
  command: ['--innodb_page_size=64k', '--innodb_log_buffer_size=32M', '--innodb_buffer_pool_size=512M']
  container_name: mysql
  # ...

6. Restart your instances, the mysql and mysql volume should be build automatically, now with the new settings.

7. Import your database dump file, maybe with:

gzip -dc < database.sql.gz | docker exec -i mysql mysql -uroot -pYOURPASSWORD

Voila! Worked very fine for me!

Java 9 offers a Matcher.replaceAll() that accepts a replacement function:

resultString = regexMatcher.replaceAll(
        m -> String.valueOf(Integer.parseInt(m.group()) * 3));

Using only native JS, something like this will work:

a = [{ value:"4a55eff3-1e0d-4a81-9105-3ddd7521d642", display:"Jamsheer"}, { value:"644838b3-604d-4899-8b78-09e4799f586f", display:"Muhammed"}, { value:"b6ee537a-375c-45bd-b9d4-4dd84a75041d", display:"Ravi"}, { value:"e97339e1-939d-47ab-974c-1b68c9cfb536", display:"Ajmal"},  { value:"a63a6f77-c637-454e-abf2-dfb9b543af6c", display:"Ryan"}]_x000D_

function comparer(otherArray){_x000D_
  return function(current){_x000D_
    return otherArray.filter(function(other){_x000D_
      return other.value == current.value && other.display == current.display_x000D_
    }).length == 0;_x000D_
  }_x000D_
}_x000D_
_x000D_
var onlyInA = a.filter(comparer(b));_x000D_
var onlyInB = b.filter(comparer(a));_x000D_
_x000D_
result = onlyInA.concat(onlyInB);_x000D_
_x000D_
console.log(result);

Python datetime objects don't have time zone info by default, and without it, Python actually violates the ISO 8601 specification (if no time zone info is given, assumed to be local time). You can use the pytz package to get some default time zones, or directly subclass tzinfo yourself:

from datetime import datetime, tzinfo, timedelta
class simple_utc(tzinfo):
    def tzname(self,**kwargs):
        return "UTC"
    def utcoffset(self, dt):
        return timedelta(0)

Then you can manually add the time zone info to utcnow():

>>> datetime.utcnow().replace(tzinfo=simple_utc()).isoformat()
'2014-05-16T22:51:53.015001+00:00'

Note that this DOES conform to the ISO 8601 format, which allows for either Z or +00:00 as the suffix for UTC. Note that the latter actually conforms to the standard better, with how time zones are represented in general (UTC is a special case.)

I am not sure if I fully understand your problem but since I had similar issue recently I will try to help you out.

Vendor bundle.

You should use CommonsChunkPlugin for that. in the configuration you specify the name of the chunk (e.g. vendor), and file name that will be generated (vendor.js).

new webpack.optimize.CommonsChunkPlugin("vendor", "vendor.js", Infinity),

Now important part, you have to now specify what does it mean vendor library and you do that in an entry section. One one more item to entry list with the same name as the name of the newly declared chunk (i.e. 'vendor' in this case). The value of that entry should be the list of all the modules that you want to move to vendor bundle. in your case it should look something like:

entry: {
    app: 'entry.js',
    vendor: ['jquery', 'jquery.plugin1']
}

JQuery as global

Had the same problem and solved it with ProvidePlugin. here you are not defining global object but kind of shurtcuts to modules. i.e. you can configure it like that:

new webpack.ProvidePlugin({
    $: "jquery"
})

And now you can just use $ anywhere in your code - webpack will automatically convert that to

require('jquery')

I hope it helped. you can also look at my webpack configuration file that is here

I love webpack, but I agree that the documentation is not the nicest one in the world... but hey.. people were saying same thing about Angular documentation in the begining :)

Edit:

To have entrypoint-specific vendor chunks just use CommonsChunkPlugins multiple times:

new webpack.optimize.CommonsChunkPlugin("vendor-page1", "vendor-page1.js", Infinity),
new webpack.optimize.CommonsChunkPlugin("vendor-page2", "vendor-page2.js", Infinity),

and then declare different extenral libraries for different files:

entry: {
    page1: ['entry.js'],
    page2: ['entry2.js'],
    "vendor-page1": [
        'lodash'
    ],
    "vendor-page2": [
        'jquery'
    ]
},

If some libraries are overlapping (and for most of them) between entry points then you can extract them to common file using same plugin just with different configuration. See this example.

This method has been tested and worked with ASP.NET Core 3.1 and Visual Studio 2019.

.vs\PROJECTNAME\config\applicationhost.config

Change "*:44320:localhost" to "*:44320:*".

<bindings>
    <binding protocol="http" bindingInformation="*:5737:localhost" />
    <binding protocol="https" bindingInformation="*:44320:*" />
</bindings>

Both links work:

• https://localhost:44320
• https://127.0.0.1:44320

Now if you want the app to work with the custom domain, just add the following line to the host file:

C:\Windows\System32\drivers\etc\hosts

127.0.0.1 customdomain

Now:

• https://customdomain:44320

NOTE: If your app works without SSL, change the protocol="http" part.

This doesn't explain why it should be like that, but it explains why it could happen. The following byte-code sets -1 to the internal updateCount flag in the SQLServerStatement constructor:

// Method descriptor #401 (Lcom/microsoft/sqlserver/jdbc/SQLServerConnection;II)V
// Stack: 5, Locals: 8
SQLServerStatement(
  com.microsoft.sqlserver.jdbc.SQLServerConnection arg0, int arg1, int arg2) 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

34 aload_0 [this]
35 iconst_m1
36 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

Now, I will not analyse all possible control-flows, but I'd just say that this is the internal default initialisation value that somehow leaks out to client code. Note, this is also done in other methods:

// Method descriptor #383 ()V
// Stack: 2, Locals: 1
final void resetForReexecute() 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

10 aload_0 [this]
11 iconst_m1
12 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

// Method descriptor #383 ()V
// Stack: 3, Locals: 3
final void clearLastResult();
0 aload_0 [this]
1 iconst_m1
2 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

In other words, you're probably safe interpreting -1 as being the same as 0. If you rely on this result value, maybe stay on the safe side and do your checks as follows:

// No rows affected
if (stmt.executeUpdate() <= 0) {
}
// Rows affected
else {
}

UPDATE: While reading Mark Rotteveel's answer, I tend to agree with him, assuming that -1 is the JDBC-compliant value for "unknown update counts". Even if this isn't documented on the relevant method's Javadoc, it's documented in the JDBC specs, chapter 13.1.2.3 Returning Unknown or Multiple Results. In this very case, it could be said that an IF .. INSERT .. statement will have an "unknown update count", as this statement isn't SQL-standard compliant anyway.

The best way to handle the LazyInitializationException is to use the JOIN FETCH directive:

Query query = session.createQuery("""
    select m
    from Model m
    join fetch m.modelType
    where modelGroup.id = :modelGroupId
    """
);

Anyway, DO NOT use the following Anti-Patterns as suggested by some of the answers:

• Open Session in View
• hibernate.enable_lazy_load_no_trans

Sometimes, a DTO projection is a better choice than fetching entities, and this way, you won't get any LazyInitializationException.

With Java 8, you can do this:

int[] haystack = {1, 2, 3};
int needle = 3;

boolean found = Arrays.stream(haystack).anyMatch(x -> x == needle);

You'd need to do

boolean found = Arrays.stream(haystack).anyMatch(x -> needle.equals(x));

if you're working with objects.

A more modern solution:

Using display: flex and flex-direction: row

form {_x000D_
  display: flex; /* 2. display flex to the rescue */_x000D_
  flex-direction: row;_x000D_
}_x000D_
_x000D_
label, input {_x000D_
  display: block; /* 1. oh noes, my inputs are styled as block... */_x000D_
}

<form>_x000D_
  <label for="name">Name</label>_x000D_
  <input type="text" id="name" />_x000D_
  <label for="address">Address</label>_x000D_
  <input type="text" id="address" />_x000D_
  <button type="submit">_x000D_
    Submit_x000D_
  </button>_x000D_
</form>

We could call startActivityForResult() directly from Fragment So You should call this.startActivityForResult(i, 1); instead of getActivity().startActivityForResult(i, 1);

Intent i = new Intent(getActivity(), SecondActivity.class);
i.putExtra("helloString", helloString);
this.startActivityForResult(i, 1);

Activity will send the Activity Result to your Fragment.

You're trying to access a 3 dimensional array with 4 de-references

You only need 3 loops instead of 4, or int myArray[10][10][10][10];

It seems that I'm late on this issue and/or it has already been answered, but, what could be done is: (in my case, I had only one tag locally so.. I deleted the old tag and retagged it with:

git tag -d v1.0
git tag -a v1.0 -m "My commit message"

Then:

git push --tags -f

That will update all tags on remote.

Could be dangerous! Use at own risk.

you can use console.log() to print object

console.log(my_object_array);

in case you have big object and want to print some of its values then you can use this custom function to print array in console

this.print = function (data,bpoint=0) {
    var c = 0;
    for(var k=0; k<data.length; k++){
        c++;
        console.log(c+'  '+data[k]);
        if(k!=0 && bpoint === k)break;  
    }
}

usage

print(array);   // to print entire obj array

or

print(array,50);  // 50 value to print only 

I tried the answers above but the generated script file was very large and I was having problems while importing the data. I ended up Detaching the database, then copying .mdf to my new machine, then Attaching it to my new version of SQL Server Management Studio.

I found instructions for how to do this on the Microsoft Website:
https://msdn.microsoft.com/en-us/library/ms187858.aspx

NOTE: After Detaching the database I found the .mdf file within this directory:
C:\Program Files\Microsoft SQL Server\

Use vscode-solution-explorer extension:

This extension adds a Visual Studio Solution File explorer panel in Visual Studio Code. Now you can navigate into your solution following the original Visual Studio structure.

Thanks @fernandoescolar

The funny symbols you're encountering are a UTF-8 BOM (Byte Order Mark). To get rid of them, open the file using the correct encoding (I'm assuming you're on Python 3):

file = open(r"D:\zzzz\names2.txt", "r", encoding="utf-8-sig")

Furthermore, for counting, you can use collections.Counter:

from collections import Counter
wordcount = Counter(file.read().split())

Display them with:

>>> for item in wordcount.items(): print("{}\t{}".format(*item))
...
snake   1
lion    2
goat    2
horse   3

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

echo "i know about Pipes, girlfriend" > thatAnswer

zsh: file exists: thatAnswer

to solve my issues.. I had to use... >!, á la..

[[ $FORCE_IT == 'YES' ]] && echo "$@" >! "$X" || echo "$@" > "$X"

Obviously, be careful with this...

The design of C# suggests that inline initialization is preferred, or it wouldn't be in the language. Any time you can avoid a cross-reference between different places in the code, you're generally better off.

There is also the matter of consistency with static field initialization, which needs to be inline for best performance. The Framework Design Guidelines for Constructor Design say this:

? CONSIDER initializing static fields inline rather than explicitly using static constructors, because the runtime is able to optimize the performance of types that don’t have an explicitly defined static constructor.

"Consider" in this context means to do so unless there's a good reason not to. In the case of static initializer fields, a good reason would be if initialization is too complex to be coded inline.

Generally can change the properties of your views in runtime:

(Button) item = (Button) findViewById(R.id.idBut);

and then...

item.setVisibility(false)

but

if you want to modify de visibility of the options from the ContextMenu, on press your button, you can activate a flag, and then in onCreateContextMenu you can do something like this:

 @Override
        public void onCreateContextMenu(ContextMenu menu, 
                View v,ContextMenu.ContextMenuInfo menuInfo) {

            super.onCreateContextMenu(menu, v, menuInfo);

                menu.setHeaderTitle(R.string.context_title);

                if (flagIsOn()) {
                    addMenuItem(menu, "Option available", true);
                } else {
                    Toast.makeText(this, "Option not available", 500).show();
                }

        }

I hope this helps

Option #1: Use Clear() function to empty the List<T> and retain it's capacity.

• Count is set to 0, and references to other objects from elements of the collection are also released.

• Capacity remains unchanged.

Option #2 - Use Clear() and TrimExcess() functions to set List<T> to initial state.

• Count is set to 0, and references to other objects from elements of the collection are also released.

• Trimming an empty List<T> sets the capacity of the List to the default capacity.

Definitions

Count = number of elements that are actually in the List<T>

Capacity = total number of elements the internal data structure can hold without resizing.

Clear() Only

List<string> dinosaurs = new List<string>();    
dinosaurs.Add("Compsognathus");
dinosaurs.Add("Amargasaurus");
dinosaurs.Add("Deinonychus");
Console.WriteLine("Count: {0}", dinosaurs.Count);
Console.WriteLine("Capacity: {0}", dinosaurs.Capacity);
dinosaurs.Clear();
Console.WriteLine("\nClear()");
Console.WriteLine("\nCount: {0}", dinosaurs.Count);
Console.WriteLine("Capacity: {0}", dinosaurs.Capacity);

Clear() and TrimExcess()

List<string> dinosaurs = new List<string>();
dinosaurs.Add("Triceratops");
dinosaurs.Add("Stegosaurus");
Console.WriteLine("Count: {0}", dinosaurs.Count);
Console.WriteLine("Capacity: {0}", dinosaurs.Capacity);
dinosaurs.Clear();
dinosaurs.TrimExcess();
Console.WriteLine("\nClear() and TrimExcess()");
Console.WriteLine("\nCount: {0}", dinosaurs.Count);
Console.WriteLine("Capacity: {0}", dinosaurs.Capacity);
