After a few futile hours battling with a 'SyntaxError: missing : after property id' message I can now expand on this topic:

border-width is a valid css property but it is not included in the jQuery css oject definition, so .css({border-width: '2px'}) will cause an error, but it's quite happy with .css({'border-width': '2px'}), presumably property names in quotes are just passed on as received.

See Improved Hex editing in the Vim Tips Wiki.

This could be a little tricky thing but the secure way is to set a javascript cookie, then picking it up by php cookie variable.Then Assign this php variable to an php session that will hold the data more securely than cookie.Then delete the cookie using javascript and redirect the page to itself. Given that you have added an php command to catch the variable, you will get it.

After Spending quite a bit of time looking into this, i came up with the solution for this; In this solution i am not using the Basic authentication but instead went with the oAuth authentication protocol. But to use Basic authentication you should be able to specify this in the "setHeaderRequest" with minimal changes to the rest of the code example. I hope this will be able to help someone else in the future:

var token_ // variable will store the token
var userName = "clientID"; // app clientID
var passWord = "secretKey"; // app clientSecret
var caspioTokenUrl = "https://xxx123.caspio.com/oauth/token"; // Your application token endpoint  
var request = new XMLHttpRequest(); 

function getToken(url, clientID, clientSecret) {
    var key;           
    request.open("POST", url, true); 
    request.setRequestHeader("Content-type", "application/json");
    request.send("grant_type=client_credentials&client_id="+clientID+"&"+"client_secret="+clientSecret); // specify the credentials to receive the token on request
    request.onreadystatechange = function () {
        if (request.readyState == request.DONE) {
            var response = request.responseText;
            var obj = JSON.parse(response); 
            key = obj.access_token; //store the value of the accesstoken
            token_ = key; // store token in your global variable "token_" or you could simply return the value of the access token from the function
        }
    }
}
// Get the token
getToken(caspioTokenUrl, userName, passWord);

If you are using the Caspio REST API on some request it may be imperative that you to encode the paramaters for certain request to your endpoint; see the Caspio documentation on this issue;

NOTE: encodedParams is NOT used in this example but was used in my solution.

Now that you have the token stored from the token endpoint you should be able to successfully authenticate for subsequent request from the caspio resource endpoint for your application

function CallWebAPI() {
    var request_ = new XMLHttpRequest();        
    var encodedParams = encodeURIComponent(params);
    request_.open("GET", "https://xxx123.caspio.com/rest/v1/tables/", true);
    request_.setRequestHeader("Authorization", "Bearer "+ token_);
    request_.send();
    request_.onreadystatechange = function () {
        if (request_.readyState == 4 && request_.status == 200) {
            var response = request_.responseText;
            var obj = JSON.parse(response); 
            // handle data as needed... 

        }
    }
} 

This solution does only considers how to successfully make the authenticated request using the Caspio API in pure javascript. There are still many flaws i am sure...

In case of mine, I solved it just by npm install protractor@latest -g and npm install webdriver-manager@latest. I am using chrome 80.x version. It worked for me in both Angular 4 & 6

curl -H "Content-Type: text/xml; charset=utf-8" \
-H "SOAPAction:" \
-d @soap.txt -X POST http://someurl

Note that if you care about speed and do not need to worry about singularities, solve() should be preferred to ginv() because it is much faster, as you can check:

require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)

t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0 

t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1 

char *s  does not have some memory allocated . You need to allocate it manually in your case . You can do it as follows
s = (char *)malloc(100) ;

This would not lead to segmentation fault error as you will not be refering to an unknown location anymore

My general answer to this kind of question on "efficiency" is almost always, which ever version of the code is most readable, is the most efficient.

That being said, I think (val.ToLowerCase() == "astringvalue") is pretty understandable at a glance by most people.

The efficience I refer to is not necesseraly in the execution of the code but rather in the maintanance and generally readability of the code in question.

Constant initializer allowed by C++ Standard only for integral or enumeration types. See 9.4.2/4 for details:

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a name- space scope if it is used in the program and the namespace scope definition shall not contain an initializer.

And 9.4.2/7:

Static data members are initialized and destroyed exactly like non-local objects (3.6.2, 3.6.3).

So you should write somewhere in cpp file:

const char* SomeClass::SOMETHING = "sommething";

java.time

With the Java 8 Date and Time API you can use the LocalDate class.

LocalDate.now().plusDays(nrOfDays)

See the Oracle Tutorial.

Updated JS Class Method

The add methods do not add duplicate classes and the remove method only removes class with exact string match.

const addClass = (selector, classList) => {
  const element = document.querySelector(selector);
  const classes = classList.split(' ')
  classes.forEach((item, id) => {
    element.classList.add(item)
  })
}

const removeClass = (selector, classList) => {
  const element = document.querySelector(selector);
  const classes = classList.split(' ')
  classes.forEach((item, id) => {
    element.classList.remove(item)
  })
}

addClass('button.submit', 'text-white color-blue') // add text-white and color-blue classes
removeClass('#home .paragraph', 'text-red bold') // removes text-red and bold classes

The recommended way in Python 3.5 and above is to use subprocess.run():

from subprocess import run
output = run("pwd", capture_output=True).stdout

A better way to handle this as of now (1.1) is to do this in Startup.cs's Configure():

app.UseExceptionHandler("/Error");

This will execute the route for /Error. This will save you from adding try-catch blocks to every action you write.

Of course, you'll need to add an ErrorController similar to this:

[Route("[controller]")]
public class ErrorController : Controller
{
    [Route("")]
    [AllowAnonymous]
    public IActionResult Get()
    {
        return StatusCode(StatusCodes.Status500InternalServerError);
    }
}

More information here.

In case you want to get the actual exception data, you may add this to the above Get() right before the return statement.

// Get the details of the exception that occurred
var exceptionFeature = HttpContext.Features.Get<IExceptionHandlerPathFeature>();

if (exceptionFeature != null)
{
    // Get which route the exception occurred at
    string routeWhereExceptionOccurred = exceptionFeature.Path;

    // Get the exception that occurred
    Exception exceptionThatOccurred = exceptionFeature.Error;

    // TODO: Do something with the exception
    // Log it with Serilog?
    // Send an e-mail, text, fax, or carrier pidgeon?  Maybe all of the above?
    // Whatever you do, be careful to catch any exceptions, otherwise you'll end up with a blank page and throwing a 500
}

Above snippet taken from Scott Sauber's blog.

Two ways to do it efficiently that I can think of:

1. inserting all the values into some sort of hashtable and checking whether the value you're inserting is already in it(expected O(n) time and O(n) space)

2. sorting the array and then checking whether adjacent cells are equal( O(nlogn) time and O(1) or O(n) space depending on the sorting algorithm)

stormdrain's solution would probably be O(n^2), as would any solution which involves scanning the array for each element searching for a duplicate

Looks like a server issue (i.e. a "GitHub" issue).
If you look at this thread, it can happen when the git-http-backend gets a corrupted heap.(and since they just put in place a smart http support...)
But whatever the actual cause is, it may also be related with recent sporadic disruption in one of the GitHub fileserver.

Do you still see this error message? Because if you do:

• check your local Git version (and upgrade to the latest one)
• report this as a GitHub bug.

Note: the Smart HTTP Support is a big deal for those of us behind an authenticated-based enterprise firewall proxy!

From now on, if you clone a repository over the http:// url and you are using a Git client version 1.6.6 or greater, Git will automatically use the newer, better transport mechanism.
Even more amazing, however, is that you can now push over that protocol and clone private repositories as well. If you access a private repository, or you are a collaborator and want push access, you can put your username in the URL and Git will prompt you for the password when you try to access it.

Older clients will also fall back to the older, less efficient way, so nothing should break - just newer clients should work better.

So again, make sure to upgrade your Git client first.

There are two ways, depending on your original timestamp:

mktime() and timegm()

http://docs.python.org/library/time.html

To get a timestamp from Date(), you'll need to divide getTime() by 1000, i.e. :

Date currentDate = new Date();
currentDate.getTime() / 1000;
// 1397132691

or simply:

long unixTime = System.currentTimeMillis() / 1000L;

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

Working Example

For more information read here

In addition, since info locals does not display the arguments to the function you're in, use

(gdb) info args

For example:

int main(int argc, char *argv[]) {
    argc = 6*7;    //Break here.
    return 0;
}

argc and argv won't be shown by info locals. The message will be "No locals."

Reference: info locals command.

Extract the contants into functions that describe them (basic refactoring):

FooBar fb = { foo(), bar() };

I know that style is very close to the one you didn't want to use, but it enables easier replacement of the constant values and also explain them (thus not needing to edit comments), if they ever change that is.

Another thing you could do (since you are lazy) is to make the constructor inline, so you don't have to type as much (removing "Foobar::" and time spent switching between h and cpp file):

struct FooBar {
  FooBar(int f, float b) : foo(f), bar(b) {}
  int foo;
  float bar;
};

malloc() and calloc() are functions from the C standard library that allow dynamic memory allocation, meaning that they both allow memory allocation during runtime.

Their prototypes are as follows:

void *malloc( size_t n);
void *calloc( size_t n, size_t t)

There are mainly two differences between the two:

• Behavior: malloc() allocates a memory block, without initializing it, and reading the contents from this block will result in garbage values. calloc(), on the other hand, allocates a memory block and initializes it to zeros, and obviously reading the content of this block will result in zeros.

• Syntax: malloc() takes 1 argument (the size to be allocated), and calloc() takes two arguments (number of blocks to be allocated and size of each block).

The return value from both is a pointer to the allocated block of memory, if successful. Otherwise, NULL will be returned indicating the memory allocation failure.

Example:

int *arr;

// allocate memory for 10 integers with garbage values
arr = (int *)malloc(10 * sizeof(int)); 

// allocate memory for 10 integers and sets all of them to 0
arr = (int *)calloc(10, sizeof(int));

The same functionality as calloc() can be achieved using malloc() and memset():

// allocate memory for 10 integers with garbage values   
arr= (int *)malloc(10 * sizeof(int));
// set all of them to 0
memset(arr, 0, 10 * sizeof(int)); 

Note that malloc() is preferably used over calloc() since it's faster. If zero-initializing the values is wanted, use calloc() instead.

Try a different port if you can't find any current running processes or killing them doesn't work. For example, try 27018 because the default is 27017.

mongod  --port 27018

I found this out with the command, mongod --help

Go to gradle.properties file (project root directory) and add these options.

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=user

systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=domain

systemProp.https.proxyHost=www.somehost.org

systemProp.https.proxyUser=user
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=localhost

As suggested above, i had similar issue with mysql-5.7.18,
i did this in this way

1. Executed this command from "MYSQL_HOME\bin\mysqld.exe --initialize-insecure"
2. then started "MYSQL_HOME\bin\mysqld.exe"
3. Connect workbench to this localhost:3306 with username 'root'
4. then executed this query "SET PASSWORD FOR 'root'@'localhost' = 'root';"

password was also updated successfully.

This might happen when you attempt to grant all privileges on all tables to another user, because the mysql.users table is considered off-limits for a user other than root.

The following however, should work:

GRANT ALL PRIVILEGES ON `%`.* TO '[user]'@'[hostname]' IDENTIFIED BY '[password]' WITH GRANT OPTION;

Note that we use `%`.* instead of *.*

If you have MySQL version >= 5.7, then you can try this:

SELECT JSON_EXTRACT(name, "$.id") AS name
FROM table
WHERE JSON_EXTRACT(name, "$.id") > 3

Output:

+-------------------------------+
| name                          | 
+-------------------------------+
| {"id": "4", "name": "Betty"}  | 
+-------------------------------+

Please check MySQL reference manual for more details:
https://dev.mysql.com/doc/refman/5.7/en/json-search-functions.html

I used this. Similar idea to other answers, but didn't see the exact approach anywhere :)

System.out.println(Integer.toBinaryString((b & 0xFF) + 0x100).substring(1));

0xFF is 255, or 11111111 (max value for an unsigned byte). 0x100 is 256, or 100000000

The & upcasts the byte to an integer. At that point, it can be anything from 0-255 (00000000 to 11111111, I excluded the leading 24 bits). + 0x100 and .substring(1) ensure there will be leading zeroes.

I timed it compared to João Silva's answer, and this is over 10 times faster. http://ideone.com/22DDK1 I didn't include Pshemo's answer as it doesn't pad properly.

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

Just adding a point to the whole discussion as to why this warning comes up (It wasn't clear to me before). The reason one gets this is as mentioned before is because 'a' in this case is a vector and the inequality 'a>0' produces another vector of TRUE and FALSE (where 'a' is >0 or not).

If you would like to instead test if any value of 'a>0', you can use functions - 'any' or 'all'

Best

You can use:

String.format("%02d", myNumber)

See also the javadocs

I think you don't have the python-opencv package.

I had the exact same problem and

sudo apt-get install python-opencv

solved the issue for me.

you can install opencv from the following link https://www.learnopencv.com/install-opencv3-on-ubuntu/ It works for me . apt-get install doesnt contain many packages of opencv

Use genfromtxt instead. It's a much more general method than loadtxt:

import numpy as np
print np.genfromtxt('col.txt',dtype='str')

Using the file col.txt:

foo bar
cat dog
man wine

This gives:

[['foo' 'bar']
 ['cat' 'dog']
 ['man' 'wine']]

If you expect that each row has the same number of columns, read the first row and set the attribute filling_values to fix any missing rows.

<script>
function SetBack(dir) {
    document.getElementById('body').style.backgroundImage=dir;
}
SetBack('url(myniftybg.gif)');
</script>

JavaScript code using ng-controller:

$scope.checkkey = function (event) {
  alert(event.keyCode);  //this will show the ASCII value of the key pressed

}

In HTML:

<input type="text" ng-keypress="checkkey($event)" />

You can now place your checks and other conditions using the keyCode method.

Sometimes a lot of troubles with it. In attribute value of datapicker data is 28-06-2014, but datepicker is show or today or nothing. I decided it in a such way:

<input type="text" class="form-control datepicker" data-value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" />

I added to the input of datapicker attribute data-value, because if call jQuery(this).val() OR jQuery(this).attr('value') - nothing works. I decided init in cycle each datapicker and take its value from attribute data-value:

 $("form .datepicker").each(function() {
        var time = jQuery(this).data('value');
        time = time.split('-');
        $(this).datepicker('setDate', new Date(time[2], time[1], time[0], 0, 0, 0));
    });

and it is works fine =)

For strong random seed I always use CryptoRNG and not Time.

using System;
using System.Security.Cryptography;

public class Program
{
    public static void Main()
    {
        var random = new Random(GetSeed());
        Console.WriteLine(random.Next());
    }

    public static int GetSeed() 
    {
        using (var rng = new RNGCryptoServiceProvider())
        {
            var intBytes = new byte[4];
            rng.GetBytes(intBytes);
            return BitConverter.ToInt32(intBytes, 0);
        }
    }
}

use array_map():

$yourArray = array_map('strtolower', $yourArray);

In case you need to lowercase nested array (by Yahya Uddin):

$yourArray = array_map('nestedLowercase', $yourArray);

function nestedLowercase($value) {
    if (is_array($value)) {
        return array_map('nestedLowercase', $value);
    }
    return strtolower($value);
}

If you $ is defined then You can iterate

var data={"id" : 1, "second" : "abcd"};
$.each(data, function() {
  var key = Object.keys(this)[0];
  var value = this[key];
  //do something with value;
}); 

You can access it by following way If you know the values of keys

data.id

or

data["id"]

try

List<TheUser> friends = jsonSerializer.Deserialize<List<TheUser>>(response);

The common way is the format() function:

>>> s = "This is an {example} with {vars}".format(vars="variables", example="example")
>>> s
'This is an example with variables'

It works fine with a multi-line format string:

>>> s = '''\
... This is a {length} example.
... Here is a {ordinal} line.\
... '''.format(length='multi-line', ordinal='second')
>>> print(s)
This is a multi-line example.
Here is a second line.

You can also pass a dictionary with variables:

>>> d = { 'vars': "variables", 'example': "example" }
>>> s = "This is an {example} with {vars}"
>>> s.format(**d)
'This is an example with variables'

The closest thing to what you asked (in terms of syntax) are template strings. For example:

>>> from string import Template
>>> t = Template("This is an $example with $vars")
>>> t.substitute({ 'example': "example", 'vars': "variables"})
'This is an example with variables'

I should add though that the format() function is more common because it's readily available and it does not require an import line.

If you mean you want to execute the function inputted, yes, that is simple:

Use this JS code:

eval(document.getElementById( -- el ID -- ).value);

Use the sizing utility classes...

I am almost sure you are not actually getting it installed correctly. Since you are trying to install it globally, you will need to run it with sudo:

sudo npm install -g bower

remove bootstrap modal background try this one

.modal-backdrop {
   background: none;
}

Short answer: use #visibilityOfElementLocated

None of the answers using isDisplayed or similar are correct. They only check if the display property is not none, not if the element can actually be seen! Selenium had a bunch of static utility methods added in the ExpectedConditions class. Two of them can be used in this case:

• visibilityOfElementLocated (element is allowed not to exist)
• visibilityOf (element must exist)

Usage

@Test
// visibilityOfElementLocated has been statically imported
public demo(){
    By searchButtonSelector = By.className("search_button");
    WebDriverWait wait = new WebDriverWait(driver, 10);
    driver.get(homeUrl);

    WebElement searchButton = wait.until(                
            visibilityOfElementLocated
            (searchButtonSelector)); 

    //clicks the search button 
    searchButton.click();

Custom visibility check running on the client

This was my answer before finding out about the utility methods on ExpectedConditions. It might still be relevant, as I assume it does more than the method mentioned above, which only checks the element has a height and a width.

In essence: this cannot be answered by Java and the findElementBy* methods and WebElement#isDisplayed alone, as they can only tell you if an element exists, not if it is actually visible. The OP hasn't defined what visible means, but it normally entails

• it has an opacity > 0
• it has the display property set to something else than none
• the visibility prop is set to visible
• there are no other elements hiding it (it's the topmost element)

Most people would also include the requirement that it is actually within the viewport as well (so a person would be able to see it).

For some reason, this quite normal need is not met by the pure Java API, while front-ends to Selenium that builds upon it often implements some variation of isVisible, which is why I knew this should be possible. And after browsing the source of the Node framework WebDriver.IO I found the source of isVisible, which is now renamed to the more aptly name of isVisibleInViewport in the 5.0-beta.

Basically, they implement the custom command as a call that delegates to a javascript that runs on the client and does the actual work! This is the "server" bit:

export default function isDisplayedInViewport () {
    return getBrowserObject(this).execute(isDisplayedInViewportScript, {
        [ELEMENT_KEY]: this.elementId, // w3c compatible
        ELEMENT: this.elementId // jsonwp compatible
    })
}

So the interesting bit is the javascript sent to run on the client:

/**
 * check if element is visible and within the viewport
 * @param  {HTMLElement} elem  element to check
 * @return {Boolean}           true if element is within viewport
 */
export default function isDisplayedInViewport (elem) {
    const dde = document.documentElement

    let isWithinViewport = true
    while (elem.parentNode && elem.parentNode.getBoundingClientRect) {
        const elemDimension = elem.getBoundingClientRect()
        const elemComputedStyle = window.getComputedStyle(elem)
        const viewportDimension = {
            width: dde.clientWidth,
            height: dde.clientHeight
        }

        isWithinViewport = isWithinViewport &&
                           (elemComputedStyle.display !== 'none' &&
                            elemComputedStyle.visibility === 'visible' &&
                            parseFloat(elemComputedStyle.opacity, 10) > 0 &&
                            elemDimension.bottom > 0 &&
                            elemDimension.right > 0 &&
                            elemDimension.top < viewportDimension.height &&
                            elemDimension.left < viewportDimension.width)

        elem = elem.parentNode
    }

    return isWithinViewport
}

This piece of JS can actually be copied (almost) verbatim into your own codebase (remove export default and replace const with var in case of non-evergreen browsers)! To use it, read it from File into a String that can be sent by Selenium for running on the client.

Another interesting and related script that might be worth looking into is selectByVisibleText.

If you haven't executed JS using Selenium before you could have a small peek into this or browse the JavaScriptExecutor API.

Usually, try to always use non-blocking async scripts (meaning #executeAsyncScript), but since we already have a synchronous, blocking script we might as well use the normal sync call. The returned object can be many types of Object, so cast approprately. This could be one way of doing it:

/** 
 * Demo of a java version of webdriverio's isDisplayedInViewport
 * https://github.com/webdriverio/webdriverio/blob/v5.0.0-beta.2/packages/webdriverio/src/commands/element/isDisplayedInViewport.js
 * The super class GuiTest just deals with setup of the driver and such
 */
class VisibleDemoTest extends GuiTest {
    public static String readScript(String name) {
        try {
            File f = new File("selenium-scripts/" + name + ".js");
            BufferedReader reader = new BufferedReader( new FileReader( file ) );
            return reader.lines().collect(Collectors.joining(System.lineSeparator()));
        } catch(IOError e){
            throw new RuntimeError("No such Selenium script: " + f.getAbsolutePath()); 
        }
    }

    public static Boolean isVisibleInViewport(RemoteElement e){
        // according to the Webdriver spec a string that identifies an element
        // should be deserialized into the corresponding web element,
        // meaning the 'isDisplayedInViewport' function should receive the element, 
        // not just the string we passed to it originally - how this is done is not our concern
        //
        // This is probably when ELEMENT and ELEMENT_KEY refers to in the wd.io implementation
        //
        // Ref https://w3c.github.io/webdriver/#dfn-json-deserialize
        return js.executeScript(readScript("isDisplayedInViewport"), e.getId());
    }

    public static Boolean isVisibleInViewport(String xPath){
        driver().findElementByXPath("//button[@id='should_be_visible']");
    }

    @Test
    public demo_isVisibleInViewport(){
        // you can build all kinds of abstractions on top of the base method
        // to make it more Selenium-ish using retries with timeouts, etc
        assertTrue(isVisibleInViewport("//button[@id='should_be_visible']"));
        assertFalse(isVisibleInViewport("//button[@id='should_be_hidden']"));
    }
}

This eclipse documentation has details on the markups in .project file: The project description file

It describes the .project file as:

When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"

From lambda answer, I have made something closer to the requirements.

boolean imageCreated = false;

Bitmap bmp = null;
Marker currentLocationMarker;
private void doSomeCustomizationForMarker(LatLng currentLocation) {
    if (!imageCreated) {
        imageCreated = true;
        Bitmap.Config conf = Bitmap.Config.ARGB_8888;
        bmp = Bitmap.createBitmap(400, 400, conf);
        Canvas canvas1 = new Canvas(bmp);

        Paint color = new Paint();
        color.setTextSize(30);
        color.setColor(Color.WHITE);

        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inMutable = true;

        Bitmap imageBitmap=BitmapFactory.decodeResource(getResources(),
                R.drawable.messi,opt);
        Bitmap resized = Bitmap.createScaledBitmap(imageBitmap, 320, 320, true);
        canvas1.drawBitmap(resized, 40, 40, color);

        canvas1.drawText("Le Messi", 30, 40, color);

        currentLocationMarker = mMap.addMarker(new MarkerOptions().position(currentLocation)
                .icon(BitmapDescriptorFactory.fromBitmap(bmp))
                // Specifies the anchor to be at a particular point in the marker image.
                .anchor(0.5f, 1));
    } else {
        currentLocationMarker.setPosition(currentLocation);
    }

}

Use split on string:

var array = coolVar.split(/-/);

This app won't run unless you update Google Play Services. I have tried it for such a long much time, but still I didn't get the map... Only a blank screen is appearing, even if I modified my Google Play Service given by the below comment..

Check your play services manifest file and check the version code for the APK file com.google.android.gms. In the below, it is "3136110". Download these APK files and install from a DOS prompt, but before installation run your target emulator.

package="com.google.android.gms"
android:versionCode="3136110"
android:versionName="3.1.36 (673201-10)

I got these APK files from this link.

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

You can also try the find command. If you only want files in the current directory:

find . -d 1 -prune -ls

Run a command on each of them?

find . -d 1 -prune -exec echo {} \;

Count lines, but only in files?

find . -d 1 -prune -type f -exec wc -l {} \;

Chrome is a Chromium-based browser and Chromium-based browsers only allow maximum 6 open socket connections at a time, when the 7th connection starts up it will just sit idle and wait for one of the 6 which are running to stop and then it will start running. Hence the error code ‘waiting for available sockets’, the 7th one will wait for one of those 6 sockets to become available and then it will start running.

You can either

• 1. Clear browser cache & cookies (https://geekdroids.com/waiting-for-available-socket/#1_Clear_browser_cache_cookies)
• 2. Flush socket pools (https://geekdroids.com/waiting-for-available-socket/#2_Flush_socket_pools)
• 3. Flush DNS (https://geekdroids.com/waiting-for-available-socket/#3_Flush_DNS)

In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to

Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).

(From How to: Break and Combine Statements in Code)

In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.

To break the statement in your question into several lines you could do the following:

U_matrix(i, j, n + 1) = _
     k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
     (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

(Leading whitespaces are ignored.)

An instance variable would probably be the way to do what you want. You could make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

#if DEBUG
private /*static*/ bool s_bDoDebugOnlyCode = false;
#endif

void foo()
{   
  // ...
#if DEBUG
  if (s_bDoDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }
#endif
 // ...
}

Just to be complete, pragmas (preprocessor directives) are considered a bit of a kludge to use to control program flow. .NET has a built-in answer for half of this problem, using the "Conditional" attribute.

private /*static*/ bool doDebugOnlyCode = false; 
[Conditional("DEBUG")]
void foo()
{   
  // ...    
  if (doDebugOnlyCode)
  {
      // Code here gets executed only when compiled with the DEBUG constant, 
      // and when the person debugging manually sets the bool above to true.  
      // It then stays for the rest of the session until they set it to false.
  }    
  // ...
}

No pragmas, much cleaner. The downside is that Conditional can only be applied to methods, so you'll have to deal with a boolean variable that doesn't do anything in a release build. As the variable exists solely to be toggled from the VS execution host, and in a release build its value doesn't matter, it's pretty harmless.

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

/* CSS for fixed-fluid layout */

.fixed {
    width: 150px;  /* the fixed width required */
    float: left;
}

.fixed + div {
     margin-left: 150px;  /* must match the fixed width in the .fixed class */
     overflow: hidden;
}


/* CSS to ensure sidebar and content are same height (optional) */

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
    position: relative;
}

.filler:after{
    background-color:inherit;
    bottom: 0;
    content: "";
    height: auto;
    min-height: 100%;
    left: 0;
    margin:inherit;
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

Just to reiterate what has been posted for other shells, in Bash the following works:

alias blah='function _blah(){ echo "First: $1"; echo "Second: $2"; };_blah'

Running the following:

blah one two

Gives the output below:

First: one
Second: two

Since Webpack v4, simply setting mode in your Webpack config will set the NODE_ENV for you (via DefinePlugin). Docs here.

You can select elements with multiple classes like so:

$("element.firstClass.anotherClass");

Simply chain the next class onto the first one, without a space (spaces mean "children of").

It resolved my problem, this is 1.7.

this is the query to accomplish what you want, (I am suggesting to use Kibana, as it helps to understand queries better)

GET my_index_name/my_type_name/_search
{
   "query":{
      "match_all":{}
   },
   size : 20,
   from : 3
}

to get all records you have to use "match_all" query.

size is the no of records you want to fetch (kind of limit). by default, ES will only return 10 records

from is like skip, skip first 3 records.

If you want to fetch exactly all the records, just use the value from the "total" field from the result once you hit this query from Kibana and the use it with "size".

Maybe you are out of inodes. Try df -i

                     2591792  136322 2455470    6% /home
/dev/sdb1            1887488 1887488       0  100% /data

Disk used 6% but inode table full.

This is my solution, it uses default setOnItemClickListener(). I had the same task to implement. Soon I'll post example and custom class on my github. Brief explanation is given. I'm not sure if the time in milliseconds is right difference for the system (See ViewConfiguration.getDoubleTapTimeout() source) to decide between single and double tap.

Edit: See it here: https://github.com/NikolaDespotoski/DoubleTapListView or https://github.com/NikolaDespotoski/DoubleTapListViewHandler

To use the math-functions you have to import Cocoa

You can see the other defined mathematical functions in the following way. Make a Cmd-Click on the function name sqrt and you enter the file with all other global math functions and constanst.

A small snippet of the file

...
func pow(_: CDouble, _: CDouble) -> CDouble

func sqrtf(_: CFloat) -> CFloat
func sqrt(_: CDouble) -> CDouble

func erff(_: CFloat) -> CFloat
...
var M_LN10: CDouble { get } /* loge(10)       */
var M_PI: CDouble { get } /* pi             */
var M_PI_2: CDouble { get } /* pi/2           */
var M_SQRT2: CDouble { get } /* sqrt(2)        */
...

My trick. Not so clean, but works well for me

In my case, onclick event was firing multiple times coz I had made a generic event handler comparatively as

  `$('div').on("click", 'a[data-toggle="tab"]',function () {
        console.log("dynamic bootstrap tab clicked");
        var href = $(this).attr('href');
        window.location.hash = href;
   });`

changed to

    `$('div#mainData').on("click", 'a[data-toggle="tab"]',function () {
        console.log("dynamic bootstrap tab clicked");
        var href = $(this).attr('href');
        window.location.hash = href;
    });`

and also have to make separate handlers for static and dynamic clicks, for static tab click

    `$('a[data-toggle="tab"]').on("click",function () {
        console.log("static bootstrap tab clicked");
        var href = $(this).attr('href');
        window.location.hash = href;
    });`

Just use a MaterialButton and the app:backgroundTint and android:textColor attributes:

<MaterialButton
  app:backgroundTint="@color/my_color"
  android:textColor="@android:color/white"/>

If you don't want Vim to mangle formatting in incoming pasted text, you might also want to consider using: :set paste. This will prevent Vim from re-tabbing your code. When done pasting, :set nopaste will return to the normal behavior.

It's also possible to toggle the mode with a single key, by adding something like set pastetoggle=<F2> to your .vimrc. More details on toggling auto-indent are here.

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.

"pwd -P" seems to work if you just want the directory, but if for some reason you want the name of the actual executable I don't think that helps. Here's my solution:

#!/bin/bash

# get the absolute path of the executable
SELF_PATH=$(cd -P -- "$(dirname -- "$0")" && pwd -P) && SELF_PATH=$SELF_PATH/$(basename -- "$0")

# resolve symlinks
while [[ -h $SELF_PATH ]]; do
    # 1) cd to directory of the symlink
    # 2) cd to the directory of where the symlink points
    # 3) get the pwd
    # 4) append the basename
    DIR=$(dirname -- "$SELF_PATH")
    SYM=$(readlink "$SELF_PATH")
    SELF_PATH=$(cd "$DIR" && cd "$(dirname -- "$SYM")" && pwd)/$(basename -- "$SYM")
done

ANSI SQL92:

• %
• _
• an ESCAPE character only if specified.

It is disappointing that many databases do not stick to the standard rules and add extra characters, or incorrectly enable ESCAPE with a default value of ‘\’ when it is missing. Like we don't already have enough trouble with ‘\’!

It's impossible to write DBMS-independent code here, because you don't know what characters you're going to have to escape, and the standard says you can't escape things that don't need to be escaped. (See section 8.5/General Rules/3.a.ii.)

Thank you SQL! gnnn

Only the file list (not even commit message):

git show --name-only --pretty=format:

E.g. open all changed files in your editor:

git show --name-only --pretty=format: | xargs "$EDITOR"

TextEditingController()..text = "new text"

For the offline tools that support multiple inputs, the best I've seen so far is https://github.com/wolverdude/GenSON/ I'd like to see a tool that takes filenames on standard input because I have thousands of files. However, I run out of open file descriptors, so make sure the files are closed. I'd also like to see JSON Schema generators that handle recursion. I am now working on generating Java classes from JSON objects in hopes of going to JSON Schema from my Java classes. Here is my GenSON script if you are curious or want to identify bugs in it.

Use the complete physical drive\path to your Target batch file in the shortcut Properties.

This does not work in Windows 10 if you use subst drives like I tried to do at first...

It depends. You could

string.match(/^abc$/)

But that would not match the following string: 'the first 3 letters of the alphabet are abc. not abc123'

I think you would want to use \b (word boundaries):

var str = 'the first 3 letters of the alphabet are abc. not abc123';_x000D_
var pat = /\b(abc)\b/g;_x000D_
console.log(str.match(pat));

Live example: http://jsfiddle.net/uu5VJ/

If the former solution works for you, I would advise against using it.

That means you may have something like the following:

var strs = ['abc', 'abc1', 'abc2']
for (var i = 0; i < strs.length; i++) {
    if (strs[i] == 'abc') {
        //do something 
    }
    else {
        //do something else
    }
}

While you could use

if (str[i].match(/^abc$/g)) {
    //do something 
}

It would be considerably more resource-intensive. For me, a general rule of thumb is for a simple string comparison use a conditional expression, for a more dynamic pattern use a regular expression.

For version v2.2.2 and newer

In version v2.2.2 and up, name property no longer exists and it shouldn't be used to define the route. path should be used instead of name and no leading slash is needed on the path. In this case use path: '404' instead of path: '/404':

 {path: '404', component: NotFoundComponent},
 {path: '**', redirectTo: '/404'}

For versions older than v2.2.2

you can use {path: '/*path', redirectTo: ['redirectPathName']}:

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

if no path matches then redirect to NotFound path

Below is the structure of SQL that you may write. You can do multiple joins by using "AND" or "OR".

Select TableA.Col1, TableA.Col2, TableB.Val
FROM TableA, 
INNER JOIN TableB
 ON TableA.Col1 = TableB.Col1 OR TableA.Col2 = TableB.Col2

From KunBetter's answer is where the money is

In Account controller:

    // POST: /Account/SendVerificationCodeSMS
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public JsonResult SendVerificationCodeSMS(string PhoneNumber)
    {
        return Json(PhoneNumber);
    }

In View:

$.ajax(
{
    url: "/Account/SendVerificationCodeSMS",
    method: "POST",
    contentType: 'application/x-www-form-urlencoded; charset=utf-8',
    dataType: "json",
    data: {
        PhoneNumber: $('[name="PhoneNumber"]').val(),
        __RequestVerificationToken: $('[name="__RequestVerificationToken"]').val()
    },
    success: function (data, textStatus, jqXHR) {
        if (textStatus == "success") {
            alert(data);
            // Do something on page
        }
        else {
            // Do something on page
        }
    },
    error: function (jqXHR, textStatus, errorThrown) {
        console.log(textStatus);
        console.log(jqXHR.status);
        console.log(jqXHR.statusText);
        console.log(jqXHR.responseText);
    }
});

It is important to set contentType to 'application/x-www-form-urlencoded; charset=utf-8' or just omit contentTypefrom the object ...

The required property is boolean:

$('form#register').find('input').each(function(){
    if(!$(this).prop('required')){
        console.log("NR");
    } else {
        console.log("IR");
    }
});

Reference: HTMLInputElement

If you are using dataset to bind in a Grid, you can add the row after you fill in the sql data adapter:

adapter.Fill(ds);
ds.Tables(0).Rows.Add();

To print all the ascii values from 0 to 255 using while loop.

#include<stdio.h>

int main(void)
{
    int a;
    a = 0;
    while (a <= 255)
    {
        printf("%d = %c\n", a, a);
        a++;
    }
    return 0;
}

If you prefer using column names, you could do something like this as an alternative:

min(data$column_name)

It's more convention than anything else.

• T is meant to be a Type
• E is meant to be an Element (List<E>: a list of Elements)
• K is Key (in a Map<K,V>)
• V is Value (as a return value or mapped value)

They are fully interchangeable (conflicts in the same declaration notwithstanding).

Just catch the submit event and prevent that, then do ajax

$(document).ready(function () {
    $('#myform').on('submit', function(e) {
        e.preventDefault();
        $.ajax({
            url : $(this).attr('action') || window.location.pathname,
            type: "GET",
            data: $(this).serialize(),
            success: function (data) {
                $("#form_output").html(data);
            },
            error: function (jXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });
});

Use cases are used to document behavior, e.g. answer this question.

A behavior extends another if it is in addition to but not necessarily part of the behavior, e.g. research the answer.

Also note that researching the answer doesn't make much sense if you are not trying to answer the question.

A behavior is included in another if it is part of the including behavior, e.g. login to stack exchange.

To clarify, the illustration is only true if you want to answer here in stack overflow :).

These are the technical definitions from UML 2.5 pages 671-672.

I highlighted what I think are important points.

Extends

An Extend is a relationship from an extending UseCase (the extension) to an extended UseCase (the extendedCase) that specifies how and when the behavior defined in the extending UseCase can be inserted into the behavior defined in the extended UseCase. The extension takes place at one or more specific extension points defined in the extended UseCase.

Extend is intended to be used when there is some additional behavior that should be added, possibly conditionally, to the behavior defined in one or more UseCases.

The extended UseCase is defined independently of the extending UseCase and is meaningful independently of the extending UseCase. On the other hand, the extending UseCase typically defines behavior that may not necessarily be meaningful by itself. Instead, the extending UseCase defines a set of modular behavior increments that augment an execution of the extended UseCase under specific conditions.

...

Includes

Include is a DirectedRelationship between two UseCases, indicating that the behavior of the included UseCase (the addition) is inserted into the behavior of the including UseCase (the includingCase). It is also a kind of NamedElement so that it can have a name in the context of its owning UseCase (the includingCase). The including UseCase may depend on the changes produced by executing the included UseCase. The included UseCase must be available for the behavior of the including UseCase to be completely described.

The Include relationship is intended to be used when there are common parts of the behavior of two or more UseCases. This common part is then extracted to a separate UseCase, to be included by all the base UseCases having this part in common. As the primary use of the Include relationship is for reuse of common parts, what is left in a base UseCase is usually not complete in itself but dependent on the included parts to be meaningful. This is reflected in the direction of the relationship, indicating that the base UseCase depends on the addition but not vice versa.

Excellent solutions Xuan, Theller.

For it to work with python 3 make the following changes

import sys, urllib.request

def reporthook(a, b, c):
    print ("% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c))
    sys.stdout.flush()
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print (url, "->", file)
    urllib.request.urlretrieve(url, file, reporthook)
print

Also, the URL you enter should be preceded by a "http://", otherwise it returns a unknown url type error.

Since you're returning a string as JSON, that string will include the opening and closing quotes in the raw response. So your response should probably look like:

"abc123XYZ=="

or whatever...You can try confirming this with Fiddler.

My guess is that the result.Content is the raw string, including the quotes. If that's the case, then result.Content will need to be deserialized before you can use it.

Here's a way to pass a dynamic object to a view (or partial view)

Add the following class anywhere in your solution (use System namespace, so its ready to use without having to add any references) -

    namespace System
    {
        public static class ExpandoHelper
        {
            public static ExpandoObject ToExpando(this object anonymousObject)
            {
                IDictionary<string, object> anonymousDictionary = HtmlHelper.AnonymousObjectToHtmlAttributes(anonymousObject);
                IDictionary<string, object> expando = new ExpandoObject();
                foreach (var item in anonymousDictionary)
                    expando.Add(item);
                return (ExpandoObject)expando;
            }

        }
    }

When you send the model to the view, convert it to Expando :

    return View(new {x=4, y=6}.ToExpando());

If you dont define name in the path field, usually the error will come. e.g.: path('crud/',ABC.as_view(),name="crud")

Just for additional context and intuition, here's an explicit and concrete example of the differences.

Assume you have the following function seen below. ( This label function, will arbitrarily split the values into 'High' and 'Low', based upon the threshold you provide as the parameter (x). )

def label(element, x):
    if element > x:
        return 'High'
    else:
        return 'Low'

In this example, lets assume our dataframe has one column with random numbers.

If you tried mapping the label function with map:

df['ColumnName'].map(label, x = 0.8)

You will result with the following error:

TypeError: map() got an unexpected keyword argument 'x'

Now take the same function and use apply, and you'll see that it works:

df['ColumnName'].apply(label, x=0.8)

Series.apply() can take additional arguments element-wise, while the Series.map() method will return an error.

Now, if you're trying to apply the same function to several columns in your dataframe simultaneously, DataFrame.applymap() is used.

df[['ColumnName','ColumnName2','ColumnName3','ColumnName4']].applymap(label)

Lastly, you can also use the apply() method on a dataframe, but the DataFrame.apply() method has different capabilities. Instead of applying functions element-wise, the df.apply() method applies functions along an axis, either column-wise or row-wise. When we create a function to use with df.apply(), we set it up to accept a series, most commonly a column.

Here is an example:

df.apply(pd.value_counts)

When we applied the pd.value_counts function to the dataframe, it calculated the value counts for all the columns.

Notice, and this is very important, when we used the df.apply() method to transform multiple columns. This is only possible because the pd.value_counts function operates on a series. If we tried to use the df.apply() method to apply a function that works element-wise to multiple columns, we'd get an error:

For example:

def label(element):
    if element > 1:
        return 'High'
    else:
        return 'Low'

df[['ColumnName','ColumnName2','ColumnName3','ColumnName4']].apply(label)

This will result with the following error:

ValueError: ('The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().', u'occurred at index Economy')

In general, we should only use the apply() method when a vectorized function does not exist. Recall that pandas uses vectorization, the process of applying operations to whole series at once, to optimize performance. When we use the apply() method, we're actually looping through rows, so a vectorized method can perform an equivalent task faster than the apply() method.

Here are some examples of vectorized functions that already exist that you do NOT want to recreate using any type of apply/map methods:

1. Series.str.split() Splits each element in the Series
2. Series.str.strip() Strips whitespace from each string in the Series.
3. Series.str.lower() Converts strings in the Series to lowercase.
4. Series.str.upper() Converts strings in the Series to uppercase.
5. Series.str.get() Retrieves the ith element of each element in the Series.
6. Series.str.replace() Replaces a regex or string in the Series with another string
7. Series.str.cat() Concatenates strings in a Series.
8. Series.str.extract() Extracts substrings from the Series matching a regex pattern.

You may want to double check the authorized_keys file permissions:

$ chmod 600 ~/.ssh/authorized_keys

Newer SSH server versions are very picky on this respect.

So actually the problem is that SMTP.sendmail and email.MIMEText need two different things.

email.MIMEText sets up the "To:" header for the body of the e-mail. It is ONLY used for displaying a result to the human being at the other end, and like all e-mail headers, must be a single string. (Note that it does not actually have to have anything to do with the people who actually receive the message.)

SMTP.sendmail, on the other hand, sets up the "envelope" of the message for the SMTP protocol. It needs a Python list of strings, each of which has a single address.

So, what you need to do is COMBINE the two replies you received. Set msg['To'] to a single string, but pass the raw list to sendmail:

emails = ['a.com','b.com', 'c.com']
msg['To'] = ', '.join( emails ) 
....
s.sendmail( msg['From'], emails, msg.as_string())

Try to minimize the use of <br> as much as you possibly can. HTML is supposed to carry content and structure, <br> is neither. A simple workaround is to wrap your input elements in <p> elements, like so:

<form name="publish" id="publish" action="publishprocess.php" method="post">

    <p><input type="text" id="title" name="title" size="60" maxlength="110" value="<?php echo $title ?>" /> - Title</p>
    <p><input type="text" id="contact" name="contact" size="24" maxlength="30" value="<?php echo $contact ?>" /> - Contact</p>

    <p>Task description (you may include task description, requirements on bidders, time requirements, etc):</p>
    <p><textarea name="detail" id="detail" rows="7" cols="60" style="font-family:Arial, Helvetica, sans-serif"><?php echo $detail ?></textarea></p>

    <p><input type="text" id="price" name="price" size="10" maxlength="20" value="<?php echo $price ?>" /> - Price</p>

    <p><input class="tagvalidate" type="text" id="tag" name="tag" size="40" maxlength="60" value="<?php echo $tag ?>" /> - Skill or Knowledge Tags</p>
    <p>Combine multiple words into single-words, space to separate up to 3 tags (example:photoshop quantum-physics computer-programming)</p>

    <p>District Restriction:<?php echo $locationtext.$cityname; ?></p>

    <p><input type="submit" id="submit" value="Submit" /></p>
</form>

SELECT Customers.* 
  FROM Customers 
 WHERE NOT EXISTS (
       SELECT *
         FROM SUBSCRIBERS AS s
         JOIN s.Cust_ID = Customers.Customer_ID) 

When using “NOT IN”, the query performs nested full table scans, whereas for “NOT EXISTS”, the query can use an index within the sub-query.

For any of those who are experiencing this on Windows and none of the above worked, try running this from cmd.exe. Executing these commands via PowerShell caused the install to fail each time.

I find myself using boost::lexical_cast for this sort of thing all the time these days. Example:

std::string input;
std::getline(std::cin,input);
int input_value;
try {
  input_value=boost::lexical_cast<int>(input));
} catch(boost::bad_lexical_cast &) {
  // Deal with bad input here
}

The pattern works just as well for your own classes too, provided they meet some simple requirements (streamability in the necessary direction, and default and copy constructors).

I think this is helpful for you

The error message is fairly self-explanatory

(a,b,c,d,e) = line.split()

expects line.split() to yield 5 elements, but in your case, it is only yielding 1 element. This could be because the data is not in the format you expect, a rogue malformed line, or maybe an empty line - there's no way to know.

To see what line is causing the issue, you could add some debug statements like this:

if len(line.split()) != 11:
    print line

As Martin suggests, you might also be splitting on the wrong delimiter.

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

Suppose you are executing a java program with nohup you can get java process id by

`ps aux | grep java`

output

xxxxx     9643  0.0  0.0  14232   968 pts/2   

then you can kill the process by typing

sudo kill 9643

or lets say that you need to kill all the java processes then just use

sudo killall java

this command kills all the java processes. you can use this with process. just give the process name at the end of the command

sudo killall {processName}

Check first your class loader.

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

if (classLoader == null) {
    classLoader = Class.class.getClassLoader();
}

classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");

// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml

I recently had a need to take this one step further, which was to make the property additions in the dynamic object, dynamic themselves, based on user defined entries. The examples here, and from Microsoft's ExpandoObject documentation, do not specifically address adding properties dynamically, but, can be surmised from how you enumerate and delete properties. Anyhow, I thought this might be helpful to someone. Here is an extremely simplified version of how to add truly dynamic properties to an ExpandoObject (ignoring keyword and other handling):

        // my pretend dataset
        List<string> fields = new List<string>();
        // my 'columns'
        fields.Add("this_thing");
        fields.Add("that_thing");
        fields.Add("the_other");

        dynamic exo = new System.Dynamic.ExpandoObject();

        foreach (string field in fields)
        {
            ((IDictionary<String, Object>)exo).Add(field, field + "_data");
        }

        // output - from Json.Net NuGet package
        textBox1.Text = Newtonsoft.Json.JsonConvert.SerializeObject(exo);

If you face with the problem at the first time installing Android Studio on your computer.

1. mklink /D "c:\Android-Sdk" "C:\Users\ **YOUR-USERNAME** \AppData\Local\Android\sdk"

2. Go to "C:\Users\ YOUR-USERNAME \AppData\Local\" path and create Android\sdk folders inside it.

3. After that you can continue installation.

Yes, generally the best way to store a file in a database is to save the byte array in a BLOB column. You will probably want a couple of columns to additionally store the file's metadata such as name, extension, and so on.

It is not always a good idea to store files in the database - for instance, the database size will grow fast if you store files in it. But that all depends on your usage scenario.

You are probably looking for System.Guid.NewGuid().

Try the following:

df[df['Col2'].isnull()]

data1.reset_index(inplace=True)

I think this is an update. I was unable to install rJava (on Windows) until I installed the JDK, as per Javac is not found and javac not working in windows command prompt. The message I was getting was

'javac' is not recognized as an internal or external command, operable program or batch file.

The JDK includes the JRE, and according to https://cran.r-project.org/web/packages/rJava/index.html the current version (0.9-7 published 2015-Jul-29) of rJava

SystemRequirements:     Java JDK 1.2 or higher (for JRI/REngine JDK 1.4 or higher), GNU make

So there you are: if rJava won't install because it can't find javac, and you have the JRE installed, then try the JDK. Also, make sure that JAVA_HOME points to the JDK and not the JRE.

Here is the sample how AES-GCM encryption/decryption can be done using Bouncy castle package.

I've found that sample when googled for possibility to decrypt data from GOlang crypto/aes api:

const (
    gcmBlockSize         = 16 // this is key size
    gcmTagSize           = 16 // this is mac
    gcmStandardNonceSize = 12 // this is nonce
)

func encrypt(data []byte, passphrase string) []byte {
    block, _ := aes.NewCipher([]byte(createHash(passphrase)))
    gcm, err := cipher.NewGCM(block)
    if err != nil {
        panic(err.Error())
    }
    nonce := make([]byte, gcm.NonceSize())
    if _, err = io.ReadFull(rand.Reader, nonce); err != nil {
        panic(err.Error())
    }
    ciphertext := gcm.Seal(nonce, nonce, data, nil)
    return ciphertext
}

.Net sample works like a charm with key (256 bit), mac (128bit) and nonce (96 bit).

I see this is quite an old post, but came across this looking for an answer for this problem. After reading some of the answers they seem very long winded, so after about 5 mins I managed to solve the problem very simply as follows:

httpd.conf for Apache leave the listen port as 80 and 'Server Name' as FQDN/IP :80.

Now for IIS go to Administrative Services > IIS Manager > 'Sites' in the Left hand nav drop down > in the right window select the top line (default web site) then bindings on the right.

Now select http > edit and change to 81 and enter your local IP for the server/pc and in domain enter either your FQDN (www.domain.com) or external IP close.

Restart both servers ensure your ports are open on both router and firewall, done.

This sounds long winded but literally took 5 mins of playing about. works perfectly.

System: Windows 8, IIS 8, Apache 2.2

I have the almost the same situation as yours; that if the screen width is less than the my specified width it should hide the div. This is the jquery code I used that worked for me.

$(window).resize(function() {

  if ($(this).width() < 1024) {

    $('.divIWantedToHide').hide();

  } else {

    $('.divIWantedToHide').show();

    }

});

I found the solution. Actually Base64 class is not available in Android. Link is given below for more information.

byte[] byteArray;                                                  
     byteArray= json.getBytes(StandardCharsets.US_ASCII);
    String encoded=Base64.encodeBytes(byteArray);
    userLogin(encoded);

Here is the link for Base64 class: http://androidcodemonkey.blogspot.com/2010/03/how-to-base64-encode-decode-android.html

The reason you separate the login and non-login shell is because the .bashrc file is reloaded every time you start a new copy of Bash. The .profile file is loaded only when you either log in or use the appropriate flag to tell Bash to act as a login shell.

Personally,

• I put my PATH setup into a .profile file (because I sometimes use other shells);
• I put my Bash aliases and functions into my .bashrc file;

• I put this

  #!/bin/bash
  #
  # CRM .bash_profile Time-stamp: "2008-12-07 19:42"
  #
  # echo "Loading ${HOME}/.bash_profile"
  source ~/.profile # get my PATH setup
  source ~/.bashrc  # get my Bash aliases
  

  in my .bash_profile file.

Oh, and the reason you need to type bash again to get the new alias is that Bash loads your .bashrc file when it starts but it doesn't reload it unless you tell it to. You can reload the .bashrc file (and not need a second shell) by typing

source ~/.bashrc

which loads the .bashrc file as if you had typed the commands directly to Bash.

I have done this javascript function: it fix your background image to your screen size in base at the most significative dimension (width od height) without change the image aspect ratio.

<script language="Javascript">

function FixBackgroundToScreen()
{
    bgImg = new Image(); 
    bgImg.src = document.body.background;

    if ((bgImg.height / window.innerHeight) < (bgImg.width / window.innerWidth))
        document.body.style.backgroundSize = "auto 100%";
    else
        document.body.style.backgroundSize = "100% auto";
};    
</script>

This function is the only think you need. It must be called with the window.onresize event and from the body.onload event. The image must be background-repeat: no-repeat; background-attachment: fixed;

<script language="Javascript">
window.onresize=function(){FixBackgroundToScreen();};
</script>

<body onload="FixBackgroundToScreen();">

You can see the function in my site www.andreamarulla.it

Sorry for my english... Andrea ;-)

For scripting purposes, I've found that curl command can do it, for example:

$ curl -s localhost:80 >/dev/null && echo Connected. || echo Fail.
Connected.
$ curl -s localhost:123 >/dev/null && echo Connected. || echo Fail.
Fail.

Possibly it may not won't work for all services, as curl can return different error codes in some cases (as per comment), so adding the following condition could work in reliable way:

[ "$(curl -sm5 localhost:8080 >/dev/null; echo $?)" != 7 ] && echo OK || echo FAIL

^{Note: Added -m5 to set maximum connect timeout of 5 seconds.}

If you would like to check also whether host is valid, you need to check for 6 exit code as well:

$ curl -m5 foo:123; [ $? != 6 -a $? != 7 ] && echo OK || echo FAIL
curl: (6) Could not resolve host: foo
FAIL

To troubleshoot the returned error code, simply run: curl host:port, e.g.:

$ curl localhost:80
curl: (7) Failed to connect to localhost port 80: Connection refused

See: man curl for full list of exit codes.

Well, those features are specific to a tool that you are using for development in those languages.

You wouldn't have those tools if (for example) you were using notepad to write code. So, maybe you should ask the question for the tool you are using.

how do i append a number into the drug_dictionary?

Do you wish to add "a number" or a set of values?

I use dictionaries to build associative arrays and lookup tables quite a bit.

Since python is so good at handling strings, I often use a string and add the values into a dict as a comma separated string

drug_dictionary = {} 

drug_dictionary={'MORPHINE':'',
         'OXYCODONE':'',
         'OXYMORPHONE':'',
         'METHADONE':'',
         'BUPRENORPHINE':'',
         'HYDROMORPHONE':'',
         'CODEINE':'',
         'HYDROCODONE':''}


drug_to_update = 'MORPHINE'

try: 
   oldvalue = drug_dictionary[drug_to_update] 
except: 
   oldvalue = ''

# to increment a value

   try: 
      newval = int(oldval) 
      newval += 1
   except: 
      newval = 1 


   drug_dictionary[drug_to_update] = "%s" % newval

# to append a value  

   try: 
      newval = int(oldval) 
      newval += 1
   except: 
      newval = 1 


   drug_dictionary[drug_to_update] = "%s,%s" % (oldval,newval) 

The Append method allows for storing a list of values but leaves you will a trailing comma

which you can remove with

drug_dictionary[drug_to_update][:-1]

the result of the appending the values as a string means that you can append lists of values as you need too and

print "'%s':'%s'" % ( drug_to_update, drug_dictionary[drug_to_update]) 

can return

'MORPHINE':'10,5,7,42,12,'

<input type="text" value="3" class="field left" readonly>

You could see in https://www.w3schools.com/tags/att_input_readonly.asp

The method to set "readonly":

$("input").attr("readonly", true)

to cancel "readonly"(work in jQuery):

$("input").attr("readonly", false)

@Jas: I don't have that code anymore, but I've found something close. I've made this to search for "components" of my application, they are just activities with a given category.

private List<String> getInstalledComponentList() {
    Intent componentSearchIntent = new Intent();
    componentSearchIntent.addCategory(Constants.COMPONENTS_INTENT_CATEGORY);
    componentSearchIntent.setAction(Constants.COMPONENTS_INTENT_ACTION_DEFAULT);
    List<ResolveInfo> ril = getPackageManager().queryIntentActivities(componentSearchIntent, PackageManager.MATCH_DEFAULT_ONLY);
    List<String> componentList = new ArrayList<String>();
    Log.d(LOG_TAG, "Search for installed components found " + ril.size() + " matches.");
    for (ResolveInfo ri : ril) {
        if (ri.activityInfo != null) {
            componentList.add(ri.activityInfo.packageName);// + ri.activityInfo.name);
            Log.d(LOG_TAG, "Found installed: " + componentList.get(componentList.size()-1));
        }
    }
    return componentList;
}

I've commented the part where it gets the activity name, but it's pretty straightforward.

Use host.docker.internal from Docker 18.03 onwards.

Just a little comment from my side since the OBJECT_ID doesn't work for me. It always returns that

`#tempTable doesn't exist

..even though it does exist. I just found it's stored with different name (postfixed by _ underscores) like so :

#tempTable________

This works well for me:

IF EXISTS(SELECT [name] FROM tempdb.sys.tables WHERE [name] like '#tempTable%') BEGIN
   DROP TABLE #tempTable;
END;

sudo python3 -m pip install mysql-connector-python

new Date().toISOString().split('T')[0];

Use COPY table TO ... WITH BINARY which is according to the documentation is "somewhat faster than the text and CSV formats." Only do this if you have millions of rows to insert, and if you are comfortable with binary data.

Here is an example recipe in Python, using psycopg2 with binary input.

To simplify this actions from accepted answer, you can also create Category for UIView (since this works for all subclasses of UIView, not only for textfields:

UIView+Additions.h:

#import <Foundation/Foundation.h>

@interface UIView (Additions)
- (void)setBorderForColor:(UIColor *)color 
                    width:(float)width 
                   radius:(float)radius;
@end

UIView+Additions.m:

#import "UIView+Additions.h"

@implementation UIView (Additions)

- (void)setBorderForColor:(UIColor *)color 
                    width:(float)width
                   radius:(float)radius
{
    self.layer.cornerRadius = radius;
    self.layer.masksToBounds = YES;
    self.layer.borderColor = [color CGColor];
    self.layer.borderWidth = width;
}

@end

Usage:

#import "UIView+Additions.h"
//...
[textField setBorderForColor:[UIColor redColor]
                       width:1.0f
                      radius:8.0f];

Quickfix

I had similar issue and I resolved it doing the following

1. Navigate to jenkins > Manage jenkins > In-process Script Approval
2. There was a pending command, which I had to approve.

Alternative 1: Disable sandbox

As this article explains in depth, groovy scripts are run in sandbox mode by default. This means that a subset of groovy methods are allowed to run without administrator approval. It's also possible to run scripts not in sandbox mode, which implies that the whole script needs to be approved by an administrator at once. This preventing users from approving each line at the time.

Running scripts without sandbox can be done by unchecking this checkbox in your project config just below your script:

Alternative 2: Disable script security

As this article explains it also possible to disable script security completely. First install the permissive script security plugin and after that change your jenkins.xml file add this argument:

-Dpermissive-script-security.enabled=true

So you jenkins.xml will look something like this:

<executable>..bin\java</executable>
<arguments>-Dpermissive-script-security.enabled=true -Xrs -Xmx4096m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=80 --webroot="%BASE%\war"</arguments>

Make sure you know what you are doing if you implement this!

In Visual Studio you can directly embed access to a file resource via the Resources tab of the Project properties ("Analytics" in this example).

The resulting file can then be accessed as a byte array by

byte[] jsonSecrets = GoogleAnalyticsExtractor.Properties.Resources.client_secrets_reporter;

Should you need it as a stream, then ( from https://stackoverflow.com/a/4736185/432976 )

Stream stream = new MemoryStream(jsonSecrets)

Just do this:

private void setImg(ImageView mImageView, Bitmap bitmap) {

    Drawable mDrawable = new BitmapDrawable(getResources(), bitmap);
    mImageView.setDrawable(mDrawable);
}

The BigDecimal(double) constructor can have unpredictable behaviors. It is preferable to use BigDecimal(String) or BigDecimal.valueOf(double).

System.out.println(new BigDecimal(135.69)); //135.68999999999999772626324556767940521240234375
System.out.println(new BigDecimal("135.69")); // 135.69
System.out.println(BigDecimal.valueOf(135.69)); // 135.69

The documentation for BigDecimal(double) explains in detail:

1. The results of this constructor can be somewhat unpredictable. One might assume that writing new BigDecimal(0.1) in Java creates a BigDecimal which is exactly equal to 0.1 (an unscaled value of 1, with a scale of 1), but it is actually equal to 0.1000000000000000055511151231257827021181583404541015625. This is because 0.1 cannot be represented exactly as a double (or, for that matter, as a binary fraction of any finite length). Thus, the value that is being passed in to the constructor is not exactly equal to 0.1, appearances notwithstanding.
2. The String constructor, on the other hand, is perfectly predictable: writing new BigDecimal("0.1") creates a BigDecimal which is exactly equal to 0.1, as one would expect. Therefore, it is generally recommended that the String constructor be used in preference to this one.
3. When a double must be used as a source for a BigDecimal, note that this constructor provides an exact conversion; it does not give the same result as converting the double to a String using the Double.toString(double) method and then using the BigDecimal(String) constructor. To get that result, use the static valueOf(double) method.

Although the accepted answer is absolutely clear, I just wanted to check efficiency in terms of time.

The best way is to print joined string of numbers converted to strings.

print(" ".join(list(map(str,l))))

Note that I used map instead of loop. I wrote a little code of all 4 different ways to compare time:

import time as t

a, b = 10, 210000
l = list(range(a, b))
tic = t.time()
for i in l:
    print(i, end=" ")

print()
tac = t.time()
t1 = (tac - tic) * 1000
print(*l)
toe = t.time()
t2 = (toe - tac) * 1000
print(" ".join([str(i) for i in l]))
joe = t.time()
t3 = (joe - toe) * 1000
print(" ".join(list(map(str, l))))
toy = t.time()
t4 = (toy - joe) * 1000
print("Time",t1,t2,t3,t4)

Result:

Time 74344.76 71790.83 196.99 153.99

The output was quite surprising to me. Huge difference of time in cases of 'loop method' and 'joined-string method'.

Conclusion: Do not use loops for printing list if size is too large( in order of 10**5 or more).

This Java/Spring example detects the end of a Download, at which point it hides the "Loading..." indicator.

Approach: On the JS side, set a Cookie with a Max Expiration Age of 2 min, and poll every second for cookie expiration. Then the server-side overrides this cookie with an earlier expiration age -- the completion of the server process. As soon as the cookie expiration is detected in the JS polling, "Loading..." is hidden.

JS Side

function buttonClick() { // Suppose this is the handler for the button that starts
    $("#loadingProgressOverlay").show();  // show loading animation
    startDownloadChecker("loadingProgressOverlay", 120);
    // Here you launch the download URL...
    window.location.href = "myapp.com/myapp/download";
}

// This JS function detects the end of a download.
// It does timed polling for a non-expired Cookie, initially set on the 
// client-side with a default max age of 2 min., 
// but then overridden on the server-side with an *earlier* expiration age 
// (the completion of the server operation) and sent in the response. 
// Either the JS timer detects the expired cookie earlier than 2 min. 
// (coming from the server), or the initial JS-created cookie expires after 2 min. 
function startDownloadChecker(imageId, timeout) {

    var cookieName = "ServerProcessCompleteChecker";  // Name of the cookie which is set and later overridden on the server
    var downloadTimer = 0;  // reference to timer object    

    // The cookie is initially set on the client-side with a specified default timeout age (2 min. in our application)
    // It will be overridden on the server side with a new (earlier) expiration age (the completion of the server operation), 
    // or auto-expire after 2 min.
    setCookie(cookieName, 0, timeout);

    // set timer to check for cookie every second
    downloadTimer = window.setInterval(function () {

        var cookie = getCookie(cookieName);

        // If cookie expired (NOTE: this is equivalent to cookie "doesn't exist"), then clear "Loading..." and stop polling
        if ((typeof cookie === 'undefined')) {
            $("#" + imageId).hide();
            window.clearInterval(downloadTimer);
        }

    }, 1000); // Every second
}

// These are helper JS functions for setting and retrieving a Cookie
function setCookie(name, value, expiresInSeconds) {
    var exdate = new Date();
    exdate.setTime(exdate.getTime() + expiresInSeconds * 1000);
    var c_value = escape(value) + ((expiresInSeconds == null) ? "" : "; expires=" + exdate.toUTCString());
    document.cookie = name + "=" + c_value + '; path=/';
}

function getCookie(name) {
    var parts = document.cookie.split(name + "=");
    if (parts.length == 2 ) {
        return parts.pop().split(";").shift();
    }
}

Java/Spring Server Side

    @RequestMapping("/download")
    public String download(HttpServletRequest request, HttpServletResponse response) throws Exception {
        //... Some logic for downloading, returning a result ...

        // Create a Cookie that will override the JS-created Max-Age-2min Cookie 
        // with an earlier expiration (same name)
        Cookie myCookie = new Cookie("ServerProcessCompleteChecker", "-1");
        myCookie.setMaxAge(0); // this is immediate expiration, 
                               // but can also add +3 sec. for any flushing concerns
        myCookie.setPath("/");
        response.addCookie(myCookie);
        //... -- presumably the download is writing to the Output Stream...
        return null;
}

import nltk is Python syntax, and as such won't work in a shell script.

To test the version of nltk and scikit_learn, you can write a Python script and run it. Such a script may look like

import nltk
import sklearn

print('The nltk version is {}.'.format(nltk.__version__))
print('The scikit-learn version is {}.'.format(sklearn.__version__))

# The nltk version is 3.0.0.
# The scikit-learn version is 0.15.2.

Note that not all Python packages are guaranteed to have a __version__ attribute, so for some others it may fail, but for nltk and scikit-learn at least it will work.

By default Gmail account is highly secured. When we use gmail smtp from non gmail tool, email is blocked. To test in our local environment, make your gmail account less secure as

1. Login to Gmail.
2. Access the URL as https://www.google.com/settings/security/lesssecureapps
3. Select "Turn on"

Turning off my VPN resolved the issue.

You can use subSequence , it's same as substr in C

 Str.subSequence(int Start , int End)

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

Maybe there is a problem with the JAR files in the local Maven repository. Try deleting the .m2/repository folder and hit Maven -> Update Project... another time to trigger Maven to download the dependencies again. I tried it and it worked for me.

You can use a loop:

with open('your_file.txt', 'w') as f:
    for item in my_list:
        f.write("%s\n" % item)

In Python 2, you can also use

with open('your_file.txt', 'w') as f:
    for item in my_list:
        print >> f, item

If you're keen on a single function call, at least remove the square brackets [], so that the strings to be printed get made one at a time (a genexp rather than a listcomp) -- no reason to take up all the memory required to materialize the whole list of strings.

I have this function for this case ..

Function GetValue(r As Range, Tag As String) As Integer
Dim c, nRet As String
Dim n, x As Integer
Dim bNum As Boolean

c = r.Value
n = InStr(c, Tag)
For x = n + 1 To Len(c)
  Select Case Mid(c, x, 1)
    Case ":":    bNum = True
    Case " ": Exit For
    Case Else: If bNum Then nRet = nRet & Mid(c, x, 1)
  End Select
Next
GetValue = val(nRet)
End Function

To fill cell BC .. (assumed that you check cell A1)

Worksheets("Übersicht_2013").Cells(i, "BC") = GetValue(range("A1"),"S")

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

AFNetworking provides async image loading into a UIImageView with placeholder support. It also supports async networking for working with APIs in general.

A degree of control is possible over how information travels from a third-party website to Facebook when a page is shared (or liked, etc.). In order to make this possible, information is sent via Open Graph meta tags in the <head> part of the website’s code.

I used tableViewCell to show multiple data, after swipe () right to left on a cell it will show two buttons Approve And reject, there are two methods, the first one is ApproveFunc which takes one argument, and the another one is RejectFunc which also takes one argument.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
        let Approve = UITableViewRowAction(style: .normal, title: "Approve") { action, index in

            self.ApproveFunc(indexPath: indexPath)
        }
        Approve.backgroundColor = .green

        let Reject = UITableViewRowAction(style: .normal, title: "Reject") { action, index in

            self.rejectFunc(indexPath: indexPath)
        }
        Reject.backgroundColor = .red



        return [Reject, Approve]
    }

    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
        return true
    }

    func ApproveFunc(indexPath: IndexPath) {
        print(indexPath.row)
    }
    func rejectFunc(indexPath: IndexPath) {
        print(indexPath.row)
    }

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

Try this, works in Ruby:

DateTime.now.to_time.utc

There is no "standard" library function to do this. The standard (perhaps surprisingly) does not actually recognise the concept of a "keyboard", albeit it does have a standard for "console input".

There are various ways to achieve it on different operating systems (see herohuyongtao's solution) but it is not portable across all platforms that support keyboard input.

Remember that C++ (and C) are devised to be languages that can run on embedded systems that do not have keyboards. (Having said that, an embedded system might not have various other devices that the standard library supports).

This matter has been debated for a long time.

use \t instead of space.

bw.write("\t");

public class RandomNumbers {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int n = 5;
        int A[] = uniqueRandomArray(n);

use with quotes

ex: adb shell "svc wifi enable"

this will work :)

I used ini_set('display_errors','off'); and it worked great.

That's because Bootstrap by default sets the width of the legend element to 100%. You can fix this by changing your legend.scheduler-border to also use:

legend.scheduler-border {
    width:inherit; /* Or auto */
    padding:0 10px; /* To give a bit of padding on the left and right */
    border-bottom:none;
}

JSFiddle example.

You'll also need to ensure your custom stylesheet is being added after Bootstrap to prevent Bootstrap overriding your styling - although your styles here should have higher specificity.

You may also want to add margin-bottom:0; to it as well to reduce the gap between the legend and the divider.

bundle is used to share data between activities , and to save state of app in oncreate() method so that app will come to know where it was stopped ... I hope it helps :)

Please check if the python version you are using is also 64 bit. If not then that could be the issue. You would be using a 32 bit python version and would have installed a 64 bit binaries for the OPENCV library.

You've got basically 2 options for "global" variables:

• use a $rootScope http://docs.angularjs.org/api/ng.$rootScope
• use a service http://docs.angularjs.org/guide/services

$rootScope is a parent of all scopes so values exposed there will be visible in all templates and controllers. Using the $rootScope is very easy as you can simply inject it into any controller and change values in this scope. It might be convenient but has all the problems of global variables.

Services are singletons that you can inject to any controller and expose their values in a controller's scope. Services, being singletons are still 'global' but you've got far better control over where those are used and exposed.

Using services is a bit more complex, but not that much, here is an example:

var myApp = angular.module('myApp',[]);
myApp.factory('UserService', function() {
  return {
      name : 'anonymous'
  };
});

and then in a controller:

function MyCtrl($scope, UserService) {
    $scope.name = UserService.name;
}

Here is the working jsFiddle: http://jsfiddle.net/pkozlowski_opensource/BRWPM/2/

To lock the screen by code you have to use the actual rotation of the screen (0, 90, 180, 270) and you have to know the natural position of it, in a smartphone the natural position will be portrait and in a tablet, it will be landscape.

Here's the code (lock and unlock methods), it has been tested in some devices (smartphones and tablets) and it works great.

public static void lockScreenOrientation(Activity activity)
{   
    WindowManager windowManager =  (WindowManager) activity.getSystemService(Context.WINDOW_SERVICE);   
    Configuration configuration = activity.getResources().getConfiguration();   
    int rotation = windowManager.getDefaultDisplay().getRotation(); 

    // Search for the natural position of the device    
    if(configuration.orientation == Configuration.ORIENTATION_LANDSCAPE &&  
       (rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) ||  
       configuration.orientation == Configuration.ORIENTATION_PORTRAIT &&   
       (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270))   
    {   
        // Natural position is Landscape    
        switch (rotation)   
        {   
            case Surface.ROTATION_0:    
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);    
                break;      
            case Surface.ROTATION_90:   
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT); 
            break;      
            case Surface.ROTATION_180: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE); 
                break;          
            case Surface.ROTATION_270: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
                break;
        }
    }
    else
    {
        // Natural position is Portrait
        switch (rotation) 
        {
            case Surface.ROTATION_0: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
            break;   
            case Surface.ROTATION_90: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
            break;   
            case Surface.ROTATION_180: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT); 
                break;          
            case Surface.ROTATION_270: 
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE); 
                break;
        }
    }
}

public static void unlockScreenOrientation(Activity activity)
{
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
}

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

Use this script: https://github.com/ricardobranco777/docker-volumes.sh

This does preserve data in volumes.

Example usage:

# Stop the container   
docker stop $CONTAINER

# Create a new image   
docker commit $CONTAINER $CONTAINER

# Save image
docker save -o $CONTAINER.tar $CONTAINER

# Save the volumes (use ".tar.gz" if you want compression)
docker-volumes.sh $CONTAINER save $CONTAINER-volumes.tar

# Copy image and volumes to another host
scp $CONTAINER.tar $CONTAINER-volumes.tar $USER@$HOST:

# On the other host:
docker load -i $CONTAINER.tar
docker create --name $CONTAINER [<PREVIOUS CONTAINER OPTIONS>] $CONTAINER

# Load the volumes
docker-volumes.sh $CONTAINER load $CONTAINER-volumes.tar

# Start container
docker start $CONTAINER

This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):

sqlcmd -S .\SQLExpress -i SqlScript.sql

Where SqlScript.sql is the script file name located at the current directory. See this Microsoft page for more examples

To follow up on the answer by user183038, here is a shell script to batch rename all xlsx files to csv while preserving the file names. The xlsx2csv tool needs to be installed prior to running.

  outext=".csv" 
  xlsx2csv $i $filename$outext
done

pod install or pod setup fetches whole repo with history when you first time run it. You don't need that commit history.

pod setup
Ctrl +C
cd ~/.cocoapods/repos 
git clone --depth 1 https://github.com/CocoaPods/Specs.git master

It takes around 2 mins on decent network connection (4Mbps). master directory is around 519M big.

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

I had the same problem, here is my description of the problem

"I created a store procedure which would generate 2200 Rows and would get executed in almost 2 seconds however after calling the store procedure from SSRS 2008 and run the report it actually never ran and ultimately I have to kill the BIDS (Business Intelligence development Studio) from task manager".

What I Tried: I tried running the SP from reportuser Login but SP was running normal for that user as well, I checked Profiler but nothing worked out.

Solution:

Actually the problem is that even though SP is generating the result but SSRS engine is taking time to read these many rows and render it back. So I added WITH RECOMPILE option in SP and ran the report .. this is when miracle happened and my problem got resolve.

If I understand them correctly (and I'm far from an expert on each) they fundamentally each have a different philosophy. I first used mercurial for 9 months. Now I've used git for 6.

hg is version control software. It's main goal is to track versions of a piece of software.

git is a time based file system. It's goal is to add another dimension to a file system. Most have files and folders, git adds time. That it happens to work awesome as a VCS is a byproduct of its design.

In hg, there's a history of the entire project it's always trying to maintain. By default I believe hg wants all changes to all objects by all users when pushing and pulling.

In git there's just a pool of objects and these tracking files (branches/heads) that determine which set of those objects represent the tree of files in a particular state. When pushing or pulling git only sends the objects needed for the the particular branches you are pushing or pulling, which is a small subset of all objects.

As far as git is concerned there is no "1 project". You could have 50 projects all in the same repo and git wouldn't care. Each one could be managed separately in the same repo and live fine.

Hg's concept of branches is branches off the main project or branches off branches etc. Git has no such concept. A branch in git is just a state of the tree, everything is a branch in git. Which branch is official, current, or newest has no meaning in git.

I don't know if that made any sense. If I could draw pictures hg might look like this where each commit is a o

             o---o---o
            /        
o---o---o---o---o---o---o---o
         \         /
          o---o---o

A tree with a single root and branches coming off of it. While git can do that and often people use it that way that's not enforced. A git picture, if there is such a thing, could easily look like this

o---o---o---o---o

o---o---o---o
         \
          o---o

o---o---o---o

In fact in some ways it doesn't even make sense to show branches in git.

One thing that is very confusing for the discussion, git and mercurial both have something called a "branch" but they are not remotely the same things. A branch in mercurial comes about when there are conflicts between different repos. A branch in git is apparently similar to a clone in hg. But a clone, while it might give similar behavior is most definitely not the same. Consider me trying these in git vs hg using the chromium repo which is rather large.

$ time git checkout -b some-new-branch
Switched to new branch 'some-new-branch'

real   0m1.759s
user   0m1.596s
sys    0m0.144s

And now in hg using clone

$ time hg clone project/ some-clone/

updating to branch default
29387 files updated, 0 files merged, 0 files removed, 0 files unresolved.
real   0m58.196s
user   0m19.901s
sys    0m8.957

Both of those are hot runs. Ie, I ran them twice and this is the second run. hg clone is the actually the same as git-new-workdir. Both of those make an entirely new working dir almost as though you had typed cp -r project project-clone. That's not the same as making a new branch in git. It's far more heavy weight. If there is true equivalent of git's branching in hg I don't know what it is.

I understand at some level hg and git might be able to do similar things. If so then there is a still a huge difference in the workflow they lead you to. In git, the typical workflow is to create a branch for every feature.

git checkout master
git checkout -b add-2nd-joypad-support
git checkout master
git checkout -b fix-game-save-bug
git checkout master
git checkout -b add-a-star-support

That just created 3 branches, each based off a branch called master. (I'm sure there's some way in git to make those 1 line each instead of 2)

Now to work on one I just do

git checkout fix-game-save-bug

and start working. Commit things, etc. Switching between branches even in a project as big as chrome is nearly instantaneous. I actually don't know how to do that in hg. It's not part of any tutorials I've read.

One other big difference. Git's stage.

Git has this idea of a stage. You can think of it as a hidden folder. When you commit you only commit what's on the stage, not the changes in your working tree. That might sound strange. If you want to commit all the changes in your working tree you'd do git commit -a which adds all the modified files to the stage and then commits them.

What's the point of the stage then? You can easily separate your commits. Imagine you edited joypad.cpp and gamesave.cpp and you want to commit them separately

git add joypad.cpp  // copies to stage
git commit -m "added 2nd joypad support"
git add gamesave.cpp  // copies to stage
git commit -m "fixed game save bug"

Git even has commands to decide which particular lines in the same file you want to copy to the stage so you can split up those commits separately as well. Why would you want to do that? Because as separate commits others can pull only the ones they want or if there was an issue they can revert just the commit that had the issue.

First of all check your internet connection.. go to safari and check by searching something on google(dont try google.com only.. because it can be cached). If it is working fine, then try now in your app. It must work. This is fired while not having proper internet connection.

I'm not sure what server side technology you are using but try using a json array. A couple of options for you to try:

{
  "address": "colombo",
  "username": "hesh",
  "password": "123",
  "registetedDate": "2015-4-3",
  "firstname": "hesh",
  "contactNo": "07762",
  "accountNo": "16161",
  "lastName": "jay"
 },
[
   1436517454492,
   1436517476993
]

If that doesn't work you may also try:

{
  freelancer: {
  "address": "colombo",
  "username": "hesh",
  "password": "123",
  "registetedDate": "2015-4-3",
  "firstname": "hesh",
  "contactNo": "07762",
  "accountNo": "16161",
  "lastName": "jay"
 },
 skills : [
       1436517454492,
       1436517476993
    ]
}

That's because of the <a> in there and not using the id which you do use a bit further to the top

Change it to:

#sub-navigation-home li.sub-navigation-home-news a 
{
 color: #C1C1C1;
 font-family: arial;
 font-size: 13.5px;
 text-align: center;
 text-transform:uppercase;
 padding: 0px 90px 0px 0px; 
}

and it will probably work

The CPP Section of the GCC Manual indicates that header files may be located in the following directories:

GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with #include in:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/g++-v3, first.

Only second approach will work. You can modify collection during iteration using iterator.remove() only. All other attempts will cause ConcurrentModificationException.

<h1 id="foo">Foo Title</h1>

is what should be used. Don't use an anchor unless you want a link.

1.

long date = curDateFld.getDate();
//convert long to string
String str = String.valueOf(date);

//convert string to long
date = Long.valueOf(str);

2.

 //convert long to string just concat long with empty string
 String str = ""+date;
//convert string to long

date = Long.valueOf(str);

An <iframe> gives you a complete window to work with. The most direct way to do what you want is to have your server give you a complete page that only contains the fragment you want to show.

As an alternative, you could just use a simple <div> and use the jQuery "load" function to load the whole page and pluck out just the section you want:

$('#target-div').load('http://www.mywebsite.com/portfolio.php #portfolio-sports');

There may be other things you need to do, and a significant difference is that the content will become part of the main page instead of being segregated into a separate window.

Curt makes a good point: the second version is clearer and will fail at load time rather than later, and unexpectedly.

Normally I don't worry about the efficiency of loading modules, since it's (a) pretty fast, and (b) mostly only happens at startup.

If you have to load heavyweight modules at unexpected times, it probably makes more sense to load them dynamically with the __import__ function, and be sure to catch ImportError exceptions, and handle them in a reasonable manner.

You can simply run

$(document).keyup(function(e) {
    console.log(e.keyCode);
});

to see the codes of pressed keys in the browser console.

Or you can find key codes here: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode#Numpad_keys

Question 3: Can you offer me some hints how to optimize these implementations without changing the way I determine the factors? Optimization in any way: nicer, faster, more "native" to the language.

The C implementation is suboptimal (as hinted at by Thomas M. DuBuisson), the version uses 64-bit integers (i.e. long datatype). I'll investigate the assembly listing later, but with an educated guess, there are some memory accesses going on in the compiled code, which make using 64-bit integers significantly slower. It's that or generated code (be it the fact that you can fit less 64-bit ints in a SSE register or round a double to a 64-bit integer is slower).

Here is the modified code (simply replace long with int and I explicitly inlined factorCount, although I do not think that this is necessary with gcc -O3):

#include <stdio.h>
#include <math.h>

static inline int factorCount(int n)
{
    double square = sqrt (n);
    int isquare = (int)square;
    int count = isquare == square ? -1 : 0;
    int candidate;
    for (candidate = 1; candidate <= isquare; candidate ++)
        if (0 == n % candidate) count += 2;
    return count;
}

int main ()
{
    int triangle = 1;
    int index = 1;
    while (factorCount (triangle) < 1001)
    {
        index++;
        triangle += index;
    }
    printf ("%d\n", triangle);
}

Running + timing it gives:

$ gcc -O3 -lm -o euler12 euler12.c; time ./euler12
842161320
./euler12  2.95s user 0.00s system 99% cpu 2.956 total

For reference, the haskell implementation by Thomas in the earlier answer gives:

$ ghc -O2 -fllvm -fforce-recomp euler12.hs; time ./euler12                                                                                      [9:40]
[1 of 1] Compiling Main             ( euler12.hs, euler12.o )
Linking euler12 ...
842161320
./euler12  9.43s user 0.13s system 99% cpu 9.602 total

Conclusion: Taking nothing away from ghc, its a great compiler, but gcc normally generates faster code.

You can enable this in Window - Preferences - General - Workspace - Refresh Automatically (called Refresh using native hooks or polling in newer builds)

The only reason I can think why this isn't enabled by default is performance related.

For example, refreshing source folders automatically might trigger a build of the workspace. Perhaps some people want more control over this.

There is also an article on the Eclipse site regarding auto refresh.

Basically, there is no external trigger that notifies Eclipse of files changed outside the workspace. Rather a background thread is used by Eclipse to monitor file changes that can possibly lead to performance issues with large workspaces.

Look the path for example this import is not correct import Navbar from '@/components/Navbar.vue' should look like this ** import Navbar from './components/Navbar.vue'**

this is the correct answer

$('#theid').css('display') == 'none'

You can also use following line to find if it is display block or none

$('.deal_details').is(':visible')

This is an "old school solution", when MERGE command does not work (I think before version 10).

UPDATE TARGET_TABLE T 
SET (T.VAL1, T.VAL2 ) =  
(SELECT S.VAL1, S.VAL2
 FROM SOURCE_TABLE S 
 WHERE T.KEY1 = S.KEY1 AND T.KEY2 = S.KEY2)
WHERE EXISTS 
(SELECT 1  
 FROM SOURCE_TABLE S 
 WHERE T.KEY1 = S.KEY1 AND T.KEY2 = S.KEY2 
   AND (T.VAL1 <> S.VAL1 OR T.VAL2 <> S.VAL2));

based from the answer of @SW4, you could also add a little animation at the end.

body > div{_x000D_
    border:1px solid grey;_x000D_
}_x000D_
html, body, #container {_x000D_
    height:100%;_x000D_
    width:100%;_x000D_
    margin:0;_x000D_
    padding:0;_x000D_
}_x000D_
#container {_x000D_
    overflow:hidden;_x000D_
    position:relative;_x000D_
}_x000D_
#hideMe {_x000D_
    -webkit-animation: cssAnimation 5s forwards; _x000D_
    animation: cssAnimation 5s forwards;_x000D_
}_x000D_
@keyframes cssAnimation {_x000D_
    0%   {opacity: 1;}_x000D_
    90%  {opacity: 1;}_x000D_
    100% {opacity: 0;}_x000D_
}_x000D_
@-webkit-keyframes cssAnimation {_x000D_
    0%   {opacity: 1;}_x000D_
    90%  {opacity: 1;}_x000D_
    100% {opacity: 0;}_x000D_
}

<div>_x000D_
<div id='container'>_x000D_
    <div id='hideMe'>Wait for it...</div>_x000D_
</div>_x000D_
</div>

Making the remaining 0.5 seconds to animate the opacity attribute. Just make sure to do the math if you're changing the length, in this case, 90% of 5 seconds leaves us 0.5 seconds to animate the opacity.

Your connection to redis is failing. Try restarting your redis server, then starting up your client again by running these 3 commands:

sudo service redis-server restart
redis-server
redis-cli

Consider if instead it was:

class RectangularRoom(object):
    def __init__(self, width, height):
        pass

    def cleanTileAtPosition(self, pos):
        pass

    def isTileCleaned(self, m, n):
        pass

and you subclass and forget to tell it how to isTileCleaned() or, perhaps more likely, typo it as isTileCLeaned(). Then in your code, you'll get a None when you call it.

• Will you get the overridden function you wanted? Definitely not.
• Is None valid output? Who knows.
• Is that intended behavior? Almost certainly not.
• Will you get an error? It depends.

raise NotImplmentedError forces you to implement it, as it will throw an exception when you try to run it until you do so. This removes a lot of silent errors. It's similar to why a bare except is almost never a good idea: because people make mistakes and this makes sure they aren't swept under the rug.

Note: Using an abstract base class, as other answers have mentioned, is better still, as then the errors are frontloaded and the program won't run until you implement them (with NotImplementedError, it will only throw an exception if actually called).

This is a simple circle as a drawable in Android.

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

   <solid 
       android:color="#666666"/>

   <size 
       android:width="120dp"
        android:height="120dp"/>
</shape>

Check if the Browser is IE -

  $ua = htmlentities($_SERVER['HTTP_USER_AGENT'], ENT_QUOTES, 'UTF-8');
  if (preg_match('~MSIE|Internet Explorer~i', $ua) || (strpos($ua, 'Trident/7.0') !== false && strpos($ua, 'rv:11.0') !== false)) {
    // do stuff for IE Here
  }

One way is to use a Boolean series to index the column df['one']. This gives you a new column where the True entries have the same value as the same row as df['one'] and the False values are NaN.

The Boolean series is just given by your if statement (although it is necessary to use & instead of and):

>>> df['que'] = df['one'][(df['one'] >= df['two']) & (df['one'] <= df['three'])]
>>> df
    one two three   que
0   10  1.2 4.2      10
1   15  70  0.03    NaN
2   8   5   0       NaN

If you want the NaN values to be replaced by other values, you can use the fillna method on the new column que. I've used 0 instead of the empty string here:

>>> df['que'] = df['que'].fillna(0)
>>> df
    one two three   que
0   10  1.2   4.2    10
1   15   70  0.03     0
2    8    5     0     0

simple example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $v)
    echo $v.',';
echo '#end main#';
?>

output

#start main# {start[1,2,3,4,5,6,7,8,9,]end} #end main#

advanced example

<?php
echo '#start main# ';
function a(){
    echo '{start[';
    for($i=1; $i<=9; $i++)
        yield $i;
    echo ']end} ';
}
foreach(a() as $k => $v){
    if($k === 5)
        break;
    echo $k.'=>'.$v.',';
}
echo '#end main#';
?>

output

#start main# {start[0=>1,1=>2,2=>3,3=>4,4=>5,#end main#
