Great-circle distance - From chord length

Here's an elegant solution applying the strategy design pattern; I hope it's readable enough.

TwoPointsDistanceCalculatorStrategy.js:

module.exports = () =>

class TwoPointsDistanceCalculatorStrategy {

    constructor() {}

    calculateDistance({ point1Coordinates, point2Coordinates }) {}
};

GreatCircleTwoPointsDistanceCalculatorStrategy.js:

module.exports = ({ TwoPointsDistanceCalculatorStrategy }) =>

class GreatCircleTwoPointsDistanceCalculatorStrategy extends TwoPointsDistanceCalculatorStrategy {

    constructor() {
        super();
    }

    /**
     * Following the algorithm documented here: 
     * https://en.wikipedia.org/wiki/Great-circle_distance#Computational_formulas
     * 
     * @param {object} inputs
     * @param {array} inputs.point1Coordinates
     * @param {array} inputs.point2Coordinates
     * 
     * @returns {decimal} distance in kelometers
     */
    calculateDistance({ point1Coordinates, point2Coordinates }) {

        const convertDegreesToRadians = require('../convert-degrees-to-radians');
        const EARTH_RADIUS = 6371;   // in kelometers

        const [lat1 = 0, lon1 = 0] = point1Coordinates;
        const [lat2 = 0, lon2 = 0] = point2Coordinates;

        const radianLat1 = convertDegreesToRadians({ degrees: lat1 });
        const radianLon1 = convertDegreesToRadians({ degrees: lon1 });
        const radianLat2 = convertDegreesToRadians({ degrees: lat2 });
        const radianLon2 = convertDegreesToRadians({ degrees: lon2 });

        const centralAngle = _computeCentralAngle({ 
            lat1: radianLat1, lon1: radianLon1, 
            lat2: radianLat2, lon2: radianLon2, 
        });

        const distance = EARTH_RADIUS * centralAngle;

        return distance;
    }
};


/**
 * 
 * @param {object} inputs
 * @param {decimal} inputs.lat1
 * @param {decimal} inputs.lon1
 * @param {decimal} inputs.lat2
 * @param {decimal} inputs.lon2
 * 
 * @returns {decimal} centralAngle
 */
function _computeCentralAngle({ lat1, lon1, lat2, lon2 }) {

    const chordLength = _computeChordLength({ lat1, lon1, lat2, lon2 });
    const centralAngle = 2 * Math.asin(chordLength / 2);

    return centralAngle;
}


/**
 * 
 * @param {object} inputs
 * @param {decimal} inputs.lat1
 * @param {decimal} inputs.lon1
 * @param {decimal} inputs.lat2
 * @param {decimal} inputs.lon2
 * 
 * @returns {decimal} chordLength
 */
function _computeChordLength({ lat1, lon1, lat2, lon2 }) {

    const { sin, cos, pow, sqrt } = Math;

    const ?X = cos(lat2) * cos(lon2) - cos(lat1) * cos(lon1);
    const ?Y = cos(lat2) * sin(lon2) - cos(lat1) * sin(lon1);
    const ?Z = sin(lat2) - sin(lat1);

    const ?XSquare = pow(?X, 2);
    const ?YSquare = pow(?Y, 2);
    const ?ZSquare = pow(?Z, 2);

    const chordLength = sqrt(?XSquare + ?YSquare + ?ZSquare);

    return chordLength;
}

convert-degrees-to-radians.js:

module.exports = function convertDegreesToRadians({ degrees }) {

    return degrees * Math.PI / 180;
};

This's following the Great-circle distance - From chord length, documented here.

It's very easy for Kotlin!

listToBeSorted.sortBy { it.distance }

Inset box-shadow does the trick.

select{
  -webkit-appearance: none;
  box-shadow: inset 0px 0px 0px 4px;
  border-radius: 0px;
  border: none;
  padding:20px 150px 20px 10px;
}

Demo

for /f "delims=" %%i in ("%0") do set "curpath=%%~dpi"
echo "%curpath%"

or

echo "%cd%"

The double quotes are needed if the path contains any & characters.

There are multiple problems here

1. Id should be unique in a page
2. For dynamic elements, you need to use event delegation using .on()

Ex

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '#remCF', function(){
        $(this).parent().parent().remove();
    });

});

Demo: Fiddle

See this demo where id properties are removed.

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '.remCF', function(){
        $(this).parent().parent().remove();
    });

});

There's time.ParseDuration which will happily accept negative durations, as per manual. Otherwise put, there's no need to negate a duration where you can get an exact duration in the first place.

E.g. when you need to substract an hour and a half, you can do that like so:

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    duration, _ := time.ParseDuration("-1.5h")

    then := now.Add(duration)

    fmt.Println("then:", then)
}

Get the first file from the control and then get the name of the file, it will ignore the file path on Chrome, and also will make correction of path for IE browsers. On saving the file, you have to use System.io.Path.GetFileName method to get the file name only for IE browsers

var fileUpload    = $("#ContentPlaceHolder1_FileUpload_mediaFile").get(0); 
var files         =  fileUpload.files; 
var mediafilename = ""; 

for (var i = 0; i < files.length; i++) { 
  mediafilename = files[i].name; 
} 

Open your activity_main.xml . Switch to Design view if you are in text view. Look for the android version,with the android robo icon. Change the android version. Problem solved.

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...

You should bring your data into long (i.e. molten) format to use it with ggplot2:

library("reshape2")
mdf <- melt(mdf, id.vars="Company", value.name="value", variable.name="Year")

And then you have to use aes( ... , group = Company ) to group them:

ggplot(data=mdf, aes(x=Year, y=value, group = Company, colour = Company)) +
    geom_line() +
    geom_point( size=4, shape=21, fill="white")

You can also simply use this:

.bg_rgba {
  background: linear-gradient(0deg, rgba(255, 255, 255, 0.9), rgba(255, 255, 255, 0.9)), url('https://picsum.photos/200');
  width: 200px;
  height: 200px;
  border: 1px solid black;
}

<div class='bg_rgba'></div>

You can change the opacity of the color to your preference.

The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided.

So in pure CSS:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;

However the mouse cursor will still change to a caret when over the element's text, so you add to that:

cursor: default;

Modern CSS is pretty elegant.

You mean like:

String names[] = {"Ankit","Bohra","Xyz"};

But you can only do this in the same statement when you declare it

Here is my working code

function emptyTextAreaCheck(textarea, submitButtonClass) {
        if(!submitButtonClass)
            submitButtonClass = ".transSubmit";

            if($(textarea).val() == '') {
                $(submitButtonClass).addClass('disabled_button');
                $(submitButtonClass).removeClass('transSubmit');
            }

        $(textarea).live('focus keydown keyup', function(){
            if($(this).val().length == 0) {
                $(submitButtonClass).addClass('disabled_button');
                $(submitButtonClass).removeClass('transSubmit');
            } else {
                $('.disabled_button').addClass('transSubmit').css({
                    'cursor':'pointer'
                }).removeClass('disabled_button');
            }
        });
    }

Short answer: You are calling a file/directory as a function instead of real function

Read on:

This kind of error happens when you import module thinking it as function and call it. So in python module is a .py file. Packages(directories) can also be considered as modules. Let's say I have a create.py file. In that file I have a function like this:

#inside create.py
def create():
  pass

Now, in another code file if I do like this:

#inside main.py file
import create
create() #here create refers to create.py , so create.create() would work here

It gives this error as am calling the create.py file as a function. so I gotta do this:

from create import create
create() #now it works.

Hope that helps! Happy Coding!

A deferred can be used in place of a mutex. This is essentially the same as the multiple ajax usage scenarios.

MUTEX

var mutex = 2;

setTimeout(function() {
 callback();
}, 800);

setTimeout(function() {
 callback();
}, 500);

function callback() {
 if (--mutex === 0) {
  //run code
 }
}

DEFERRED

function timeout(x) {
 var dfd = jQuery.Deferred();
 setTimeout(function() {
  dfd.resolve();
 }, x);
 return dfd.promise();
}

jQuery.when(
timeout(800), timeout(500)).done(function() {
 // run code
});

When using a Deferred as a mutex only, watch out for performance impacts (http://jsperf.com/deferred-vs-mutex/2). Though the convenience, as well as additional benefits supplied by a Deferred is well worth it, and in actual (user driven event based) usage the performance impact should not be noticeable.

If you include the following code at the top of your script, matplotlib will run inline when in an IPython environment (like jupyter, hydrogen atom plugin...), and it will still work if you launch the script directly via command line (matplotlib won't run inline, and the charts will open in a pop-ups as usual).

from IPython import get_ipython
ipy = get_ipython()
if ipy is not None:
    ipy.run_line_magic('matplotlib', 'inline')

*Updated

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

}

There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.

Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:

public class A {
    public static String VALUE = "Aaa";
}

public class B extends A {
    public static String VALUE = "Bbb";
}

Direct access to the static variable:

A.VALUE (="Aaa")
B.VALUE (="Bbb")

Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):

new B().VALUE (="Bbb")

So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.

Now to the point where it gets tricky: Interfaces can also have static variables.

public interface C {
    public static String VALUE = "Ccc";
}

public interface D {
    public static String VALUE = "Ddd";
}

Let's remove the static variable from B, and observe following situations:

• B implements C, D
• B extends A implements C
• B extends A implements C, D
• B extends A implements C where A implements D
• B extends A implements C where C extends D
• ...

The statement new B().VALUE is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:

error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match

And that's exactly the reason why static variables should be accessed in a static way.

You can access the iterator methods directly:

std::vector<int> *intVec;
std::vector<int>::iterator it;

for( it = intVec->begin(); it != intVec->end(); ++it )
{
}

If you want the array-access operator, you'd have to de-reference the pointer. For example:

std::vector<int> *intVec;

int val = (*intVec)[0];

If you have directories containing really (>100'000) many files, here is a (non-portable) way to go:

String directoryPath = "a path";

// -f flag is important, because this way ls does not sort it output,
// which is way faster
String[] params = { "/bin/sh", "-c",
    "ls -f " + directoryPath + " | wc -l" };
Process process = Runtime.getRuntime().exec(params);
BufferedReader reader = new BufferedReader(new InputStreamReader(
    process.getInputStream()));
String fileCount = reader.readLine().trim() - 2; // accounting for .. and .
reader.close();
System.out.println(fileCount);

To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.

SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC

If you care for it to be in the same order as before you can use a common table expression for that:

;WITH CTE AS (
    SELECT TOP 1000 *
    FROM [SomeTable]
    ORDER BY MySortColumn DESC
)

SELECT * 
FROM CTE
ORDER BY MySortColumn

If you really need single quotes, apostrophes, you can use

html    | numeric | hex
‘ | ‘  | ‘ // for the left/beginning single-quote and
’ | ’  | ’ // for the right/ending single-quote

For python 3

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)

• What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?

I'm not sure at what level you are looking for an answer at, so let's take a little trip. Some of this you may already know.

When you build your project, Xcode invokes clang for Objective-C targets and swift/swiftc for Swift targets. Both of these compilers compile the app to an intermediate representation (IR), one of these IRs is bitcode. From this IR, a program called LLVM takes over and creates the binaries needed for x86 32 and 64 bit modes (for the simulator) and arm6/arm7/arm7s/arm64 (for the device). Normally, all of these different binaries are lumped together in a single file called a fat binary.

The ENABLE_BITCODE option cuts out this final step. It creates a version of the app with an IR bitcode binary. This has a number of nice features, but one giant drawback: it can't run anywhere. In order to get an app with a bitcode binary to run, the bitcode needs to be recompiled (maybe assembled or transcoded… I'm not sure of the correct verb) into an x86 or ARM binary.

When a bitcode app is submitted to the App Store, Apple will do this final step and create the finished binaries.

Right now, bitcode apps are optional, but history has shown Apple turns optional things into requirements (like 64 bit support). This usually takes a few years, so third party developers (like Parse) have time to update.

• can I use the above method without any negative impact and without compromising a future appstore submission?

Yes, you can turn off ENABLE_BITCODE and everything will work just like before. Until Apple makes bitcode apps a requirement for the App Store, you will be fine.

• Are there any performance impacts if I enable / disable it?

There will never be negative performance impacts for enabling it, but internal distribution of an app for testing may get more complicated.

As for positive impacts… well that's complicated.

For distribution in the App Store, Apple will create separate versions of your app for each machine architecture (arm6/arm7/arm7s/arm64) instead of one app with a fat binary. This means the app installed on iOS devices will be smaller.

In addition, when bitcode is recompiled (maybe assembled or transcoded… again, I'm not sure of the correct verb), it is optimized. LLVM is always working on creating new a better optimizations. In theory, the App Store could recreate the separate version of the app in the App Store with each new release of LLVM, so your app could be re-optimized with the latest LLVM technology.

myvariable=$(mysql database -u $user -p$password | SELECT A, B, C FROM table_a)

without the blank space after -p. Its trivial, but without don't work.

Node.js is used for easily building fast, scalable network applications

In JSF 2.2 it's possible to use passthrough elements:

<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:jsf="http://xmlns.jcp.org/jsf">
    ...
    <div jsf:id="id1" />
    ...
</html>

The requirement is to have at least one attribute in the element using jsf namespace.

For static import select the field and press Ctrl+Shift+M

Regex is compiled so for speed create it once and reuse it.
The new takes longer than the IsMatch.
This only checks for all digits.
It does not check for range.
If you need to test range then TryParse is the way to go.

private static Regex regexInt = new Regex("^\\d+$");
static bool CheckReg(string value)
{
    return regexInt.IsMatch(value);
}

install react-router-dom

then create two components one for valid users and other for invalid users.

try this on app.js

import React from 'react';

import {
BrowserRouter as Router,
Route,
Link,
Switch,
Redirect
} from 'react-router-dom';

import ValidUser from "./pages/validUser/validUser";
import InValidUser from "./pages/invalidUser/invalidUser";
const loggedin = false;

class App extends React.Component {
 render() {
    return ( 
      <Router>
      <div>
        <Route exact path="/" render={() =>(
          loggedin ? ( <Route  component={ValidUser} />)
          : (<Route component={InValidUser} />)
        )} />

        </div>
      </Router>
    )
  }
}
export default App;

use the JSON function >

JSON.parse(theString)

Let dictionary be :
dict={'key':['value1','value2']}

If you know the key :
print(len(dict[key]))

else :
val=[len(i) for i in dict.values()]
print(val[0])
# for printing length of 1st key value or length of values in keys if all keys have same amount of values.

To revisit an old thread, my issue was that one of the "AddressTo" email addresses was not valid. Removing that email address removed the error.

Add the current directory ( . ) to PATH to be able to execute a script, just by typing in its name, that resides in the current directory:

PATH=.:$PATH

If you have your text in your_text variable, you can use:

your_text[0..29]

angular.module('testAppControllers', [])
    .controller('ctrlOne', function ($scope) {
        $scope.$broadcast('test');
    })
    .controller('ctrlTwo', function ($scope) {
        $scope.$on('test', function() {
        });
    });

Here's another example that was tested, and will match search & replace patterns:

import fileinput
import sys

def replaceAll(file,searchExp,replaceExp):
    for line in fileinput.input(file, inplace=1):
        if searchExp in line:
            line = line.replace(searchExp,replaceExp)
        sys.stdout.write(line)

Example use:

replaceAll("/fooBar.txt","Hello\sWorld!$","Goodbye\sWorld.")

Following code block shows how to calculate the difference in number of days between two dates using MomentJS.

var now = moment(new Date()); //todays date
var end = moment("2015-12-1"); // another date
var duration = moment.duration(now.diff(end));
var days = duration.asDays();
console.log(days)

use \\: instead of \:.. the \ has special meaning in java strings.

You need to set$final[$id] to an array before adding elements to it. Intiialize it with either

$final[$id] = array();
$final[$id][0] = 3;
$final[$id]['link'] = "/".$row['permalink'];
$final[$id]['title'] = $row['title'];

or

As of Python 3.8, use missing_ok=True and pathlib.Path.unlink (docs here)

from pathlib import Path

my_file = Path("./dir1/dir2/file.txt")

# Python 3.8+
my_file.unlink(missing_ok=True)

# Python 3.7 and earlier
if my_file.exists():
    my_file.unlink()

patterns[1]="1\.2\.3\.4.*Has exploded"
patterns[2]="5\.6\.7\.8.*Has died"
patterns[3]="\!9\.10\.11\.12.*Has exploded"

for i in {1..3}
 do
grep "${patterns[$i]}" logfile.log
done

should be the the same as

egrep "(1\.2\.3\.4.*Has exploded|5\.6\.7\.8.*Has died)" logfile.log | egrep -v "9\.10\.11\.12.*Has exploded"    

Same issue I'm getting in my MYSQL while running sql script Please look into below image.. Error code 1206: The number of locks exceeds the lock table size Picture

This is Mysql configuration issue so I made some changes in my.ini and It's working on my system & issue resolved.

We need to make some changes in my.ini which is available on following Path:- C:\ProgramData\MySQL\MySQL Server 5.7\my.ini and please update following changes in my.ini config file fields:-

key_buffer_size=64M
read_buffer_size=64M
read_rnd_buffer_size=128M
innodb_log_buffer_size=10M
innodb_buffer_pool_size=256M
query_cache_type=2
max_allowed_packet=16M

After all above changes please restart the MYSQL Service. Please refer the image:- Microsoft MYSQL Service Picture

My user account did not have the permissions to alter the database and table, as suggested in this solution.

If, like me, you don't care about the character collation (you are using the '=' operator), you can apply the reverse fix. Run this before your SELECT:

SET collation_connection = 'latin1_swedish_ci';

I think we better adopt a new file inclusion syntax (so won't mess up with code blocks, I think the C style inclusion is totally wrong), and I wrote a small tool in Perl, naming cat.pl, because it works like cat (cat a.txt b.txt c.txt will merge three files), but it merges files in depth, not in width. How to use?

$ perl cat.pl <your file>

The syntax in detail is:

• recursive include files: @include <-=path=
• just include one: %include <-=path=

It can properly handle file inclusion loops (if a.txt <- b.txt, b.txt <- a.txt, then what you expect?).

Example:

a.txt:

a.txt

    a <- b

    @include <-=b.txt=

a.end

b.txt:

b.txt

    b <- a

    @include <-=a.txt=

b.end

perl cat.pl a.txt > c.txt, c.txt:

a.txt

    a <- b

    b.txt

        b <- a

        a.txt

            a <- b

            @include <-=b.txt= (note:won't include, because it will lead to infinite loop.)

        a.end

    b.end

a.end

I also wrote a Java version having an identical effect (not the same, but close).

As Java has no pointer data types, it is impossible to use pointers in Java. Even the few experts will not be able to use pointers in java.

The following example using the iris dataset works fine:

dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
      id.vars = "Species")
ggplot(aes(x = 1:nrow(iris), y = value, color = variable), data = dat) +  
      geom_point() + geom_line()

A cleaner, more reliable way is to go into redis-cli and then type shutdown

In redis-cli, type help @server and you will see this near the bottom of the list:

SHUTDOWN - summary: Synchronously save the dataset to disk and then shut down the server since: 0.07

And if you have a redis-server instance running in a terminal, you'll see this:

User requested shutdown...
[6716] 02 Aug 15:48:44 * Saving the final RDB snapshot before exiting.
[6716] 02 Aug 15:48:44 * DB saved on disk
[6716] 02 Aug 15:48:44 # Redis is now ready to exit, bye bye...

Have the element display as a block:

display: block;

In MSSQL, this could be the way:

select distinct city from station 
where
right(city,1) in ('a', 'e', 'i', 'o','u') and left(city,1) in ('a', 'e', 'i', 'o','u') 

You need to loop over each of the elements in the slice and test. Equality for slices is not defined. However, there is a bytes.Equal function if you are comparing values of type []byte.

func testEq(a, b []Type) bool {

    // If one is nil, the other must also be nil.
    if (a == nil) != (b == nil) { 
        return false; 
    }

    if len(a) != len(b) {
        return false
    }

    for i := range a {
        if a[i] != b[i] {
            return false
        }
    }

    return true
}

If you only want to return a blank when B2 is blank you can use an additional IF function for that scenario specifically, i.e.

=IF(B2="","",VLOOKUP(B2,Index!A1:B12,2,FALSE))

or to return a blank with any error from the VLOOKUP (e.g. including if B2 is populated but that value isn't found by the VLOOKUP) you can use IFERROR function if you have Excel 2007 or later, i.e.

=IFERROR(VLOOKUP(B2,Index!A1:B12,2,FALSE),"")

in earlier versions you need to repeat the VLOOKUP, e.g.

=IF(ISNA(VLOOKUP(B2,Index!A1:B12,2,FALSE)),"",VLOOKUP(B2,Index!A1:B12,2,FALSE))

Answer (Basic is advance!):

Error: 10060 Adding a timeout parameter to request solved the issue for me.

Example 1

import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)

Example 2

A similar error also occurred while I was making a GET request. Again, passing a timeout parameter solved the 10060 Error.

response = requests.get(param_url, timeout=20)

Try using String.getBytes(). It returns a byte[] representing string data. Example:

String data = "sample data";
byte[] byteData = data.getBytes();

Another way is to use a lambda expression. Depending on interpreter version and whether you wish to create a sorted dictionary or sorted key-value tuples (as the OP does), this may even be faster than the accepted answer.

d = {'aa': 3, 'bb': 4, 'cc': 2, 'dd': 1}
s = sorted(d.items(), key=lambda x: x[1], reverse=True)

for k, v in s:
    print(k, v)

if you are using it in windows, be sure to add the path to the db in "" and also to use double slash \ in the path to make sure windows understands it.

if div.title is a div then put this:

left: 0;

You could use a subselect combined with a UNION. Whenever you can return the same fields for more than one condition use OR with the parenthesis as in this example:

SELECT * FROM
  (SELECT val1, val2 FROM table1 WHERE (condition1 is true) 
                                    OR (condition2 is true))
UNION
SELECT * FROM
  (SELECT val5, val6 FROM table7 WHERE (condition9 is true) 
                                    OR (condition4 is true))

Use this code:

'{:x}'.format(int(line))

it allows you to specify a number of digits too:

'{:06x}'.format(123)
# '00007b'

For Python 2.6 use

'{0:x}'.format(int(line))

or

'{0:06x}'.format(int(line))

By creating a .gitignore file. See here for details: Git Book - Ignoring files

Also check this one out: How do you make Git ignore files without using .gitignore?

just run these command

sudo apt-get install phpmyadmin php-mbstring php-gettext

sudo service apache2 restart

Or you can follow this post...

You use

#main_text .title {
  /* Properties */
}

If you just put a space between the selectors, styles will apply to all children (and children of children) of the first. So in this case, any child element of #main_text with the class name title. If you use > instead of a space, it will only select the direct child of the element, and not children of children, e.g.:

#main_text > .title {
  /* Properties */
}

Either will work in this case, but the first is more typically used.

The reason may be that watcher is declared as local variable to a method and it is garbage collected when the method finishes. You should declare it as a class member. Try the following:

FileSystemWatcher watcher;

private void watch()
{
  watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                         | NotifyFilters.FileName | NotifyFilters.DirectoryName;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);
  watcher.EnableRaisingEvents = true;
}

private void OnChanged(object source, FileSystemEventArgs e)
{
  //Copies file to another directory.
}

List myList = new ArrayList(collection);
Collections.sort(myList);

… should do the trick however. Add flavour with Generics where applicable.

Received this error while using the openAM Fedlet on IIS7

Changing the user account for the default website resolved the issue. Ideally, you would want this to be a service account. Perhaps even the IUSR account. Suggest looking up methods for IIS hardening to nail it down completely.

A solution working with map built-in fonction !

arg_names = ['command' ,'operation', 'parameter']
args = map(None, arg_names, sys.argv)
args = {k:v for (k,v) in args}

Then you just have to call your parameters like this:

if args['operation'] == "division":
    if not args['parameter']:
        ...
    if args['parameter'] == "euclidian":
        ...

All you need is to set values first to your RadioButton, for example:

RadioButton radioButton = (RadioButton)findViewById(R.id.radioButton);      
radioButton.setId(1);        //some int value

and then whenever this spacific radioButton will be chosen you can pull its value by the Id you gave it with

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup);                     
int whichIndex = radioGroup.getCheckedRadioButtonId(); //of course the radioButton
                                                       //should be inside the "radioGroup"
                                                       //in the XML

Cheers!

Your code works fine. When I ran it I got the output:

The values in the file input.txt are:
1
2
3
4
5
6
7
8
9
10
The sum of the values is: 55
The mean value is: 5.5

But it could still be improved.

You are iterating over the vector using indexes. This is not the "STL Way" -- you should be using iterators, to wit:

typedef vector<double> doubles;
for( doubles::const_iterator it = v.begin(), it_end = v.end(); it != it_end; ++it )
{
    total += *it;
    mean = total / v.size();
}

This is better for a number of reasons discussed here and elsewhere, but here are two main reasons:

1. Every container provides the iterator concept. Not every container provides random-access (eg, indexed access).
2. You can generalize your iteration code.

Point number 2 brings up another way you can improve your code. Another thing about your code that isn't very STL-ish is the use of a hand-written loop. <algorithm>s were designed for this purpose, and the best code is the code you never write. You can use a loop to compute the total and mean of the vector, through the use of an accumulator:

#include <numeric>
#include <functional>
struct my_totals : public std::binary_function<my_totals, double, my_totals>
{
    my_totals() : total_(0), count_(0) {};
    my_totals operator+(double v) const
    {
        my_totals ret = *this;
        ret.total_ += v;
        ++ret.count_;
        return ret;
    }
    double mean() const { return total_/count_; }
    double total_;
    unsigned count_;
};

...and then:

my_totals ttls = std::accumulate(v.begin(), v.end(), my_totals());
cout << "The sum of the values is: " << ttls.total_ << endl;
cout << "The mean value is: " << ttls.mean() << endl;

EDIT:

If you have the benefit of a C++0x-compliant compiler, this can be made even simpler using std::for_each (within #include <algorithm>) and a lambda expression:

double total = 0;
for_each( v.begin(), v.end(), [&total](double  v) { total += v; });
cout << "The sum of the values is: " << total << endl;
cout << "The mean value is: " << total/v.size() << endl;

There's a special function n() in dplyr to count rows (potentially within groups):

library(dplyr)
mtcars %>% 
  group_by(cyl, gear) %>% 
  summarise(n = n())
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

But dplyr also offers a handy count function which does exactly the same with less typing:

count(mtcars, cyl, gear)          # or mtcars %>% count(cyl, gear)
#Source: local data frame [8 x 3]
#Groups: cyl [?]
#
#    cyl  gear     n
#  (dbl) (dbl) (int)
#1     4     3     1
#2     4     4     8
#3     4     5     2
#4     6     3     2
#5     6     4     4
#6     6     5     1
#7     8     3    12
#8     8     5     2

In android studio:

1. switch to Project view so you can see the actual project folder structure.
2. find google-services.json file and drag it to the app directory (for some reason when I added it using file explorer, it put it in the gradle folder).
3. Clean/Rebuild project.

It worked fine for me from there.

I've been debuging, and refactoring code to solve this error for the last four hours. A post above led me to see the problem:

Property before: startPoint = [[DataPoint alloc] init] ; startPoint= [DataPointList objectAtIndex: 0];
. . . x = startPoint.x - 10; // EXC_BAD_ACCESS

Property after: startPoint = [[DataPoint alloc] init] ; startPoint = [[DataPointList objectAtIndex: 0] retain];

Goodbye EXC_BAD_ACCESS

String localFormat = android.text.format.DateFormat.getBestDateTimePattern(Locale.getDefault(), "EEEE MMMM d");
return new SimpleDateFormat(localFormat, Locale.getDefault()).format(localMidnight);

will return a format based on device's language. Note that getBestDateTimePattern() returns "the best possible localized form of the given skeleton for the given locale"

After establising the connection and executing the query try this:

 ResultSet resultSet;
 int columnCount = resultSet.getMetaData().getColumnCount();
 System.out.println("column count : "+columnCount);

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

you can also use this code...

datePicker = (DatePicker) findViewById(R.id.schedule_datePicker);
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth() + 1;
int year = datePicker.getYear();


SimpleDateFormat dateFormatter = new SimpleDateFormat("MM-dd-yyyy");
Date d = new Date(year, month, day);
String strDate = dateFormatter.format(d);

You need to convert your wildcard expression to a regular expression. For example:

    private bool WildcardMatch(String s, String wildcard, bool case_sensitive)
    {
        // Replace the * with an .* and the ? with a dot. Put ^ at the
        // beginning and a $ at the end
        String pattern = "^" + Regex.Escape(wildcard).Replace(@"\*", ".*").Replace(@"\?", ".") + "$";

        // Now, run the Regex as you already know
        Regex regex;
        if(case_sensitive)
            regex = new Regex(pattern);
        else
            regex = new Regex(pattern, RegexOptions.IgnoreCase);

        return(regex.IsMatch(s));
    } 

I had this issue for a day until I found the real resolution. Instead of trying to force unmount an smb share that is hung, mount the share with the "soft" option. If a process attempts to connect to the share that is not available it will stop trying after a certain amount of time.

soft Make the mount soft. Fail file system calls after a number of seconds.

mount -t smbfs -o soft //username@server/share /users/username/smb/share

stat /users/username/smb/share/file
stat: /users/username/smb/share/file: stat: Operation timed out

May not be a real answer to your question but it is a solution to the problem

One additional reason to allow and use std::unique_ptr<T[]>, that hasn't been mentioned in the responses so far: it allows you to forward-declare the array element type.

This is useful when you want to minimize the chained #include statements in headers (to optimize build performance.)

For instance -

myclass.h:

class ALargeAndComplicatedClassWithLotsOfDependencies;

class MyClass {
   ...
private:
   std::unique_ptr<ALargeAndComplicatedClassWithLotsOfDependencies[]> m_InternalArray;
};

myclass.cpp:

#include "myclass.h"
#include "ALargeAndComplicatedClassWithLotsOfDependencies.h"

// MyClass implementation goes here

With the above code structure, anyone can #include "myclass.h" and use MyClass, without having to include the internal implementation dependencies required by MyClass::m_InternalArray.

If m_InternalArray was instead declared as a std::array<ALargeAndComplicatedClassWithLotsOfDependencies>, or a std::vector<...>, respectively - the result would be attempted usage of an incomplete type, which is a compile-time error.

The specification does not limit the length of an HTTP Get request but the different browsers implement their own limitations. For example Internet Explorer has a limitation implemented at 2083 characters.

Another way is to use the DateTime class, this way you can also specify the timezone. Note: PHP 5.3 or higher.

// For the current date
function isTodayWeekend() {
    $currentDate = new DateTime("now", new DateTimeZone("Europe/Amsterdam"));
    return $currentDate->format('N') >= 6;
}

If you need to be able to check a certain date string, you can use DateTime::createFromFormat

function isWeekend($date) {
    $inputDate = DateTime::createFromFormat("d-m-Y", $date, new DateTimeZone("Europe/Amsterdam"));
    return $inputDate->format('N') >= 6;
}

The beauty of this way is that you can specify the timezone without changing the timezone globally in PHP, which might cause side-effects in other scripts (for ex. Wordpress).

Additionally you may want to get managers and their reports count with -

SELECT e2.ename ,count(e1.ename)  FROM employee_s e1 LEFT OUTER JOIN employee_s e2 
ON e1.manager_id = e2.eid
group by e2.ename;

You can do this:

df.rename(columns={ df.columns[1]: "whatever" })

I needed to enable the JUnit plugin, after I linked my project with the jar files.

To enable the JUnit plugin, go to File->Settings, type "JUnit" in the search bar, and under "Plugins," check "JUnit.

vikingsteve's advice above will probably get the libraries linked right. Otherwise, open File->Project Structure, go to Libraries, hit the plus, and then browse to

C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 14.1.1\lib\

and add these jar files:

hamcrest-core-1.3.jar
junit-4.11.jar 
junit.jar 

Yes, it is possible. You will need to define 2 FKs for 3rd table. Each FK pointing to the required field(s) of one table (ie 1 FK per foreign table).

Use:

$.ajax({
    url: 'feed/4', type: 'POST', data: "_METHOD=PUT&accessToken=63ce0fde", success: function(data) {
        console.log(data);
    }
});

Always remember to use _METHOD=PUT.

In Windows 7 and later, this will do the trick for you

• Select the file/files.
• Hold the shift key and then right-click on the selected file/files.
• You will see Copy as Path. Click that.
• Open a Notepad file and paste and you will be good to go.

The menu item Copy as Path is not available in Windows XP.

In Rails 2

l = Location.find(:id => id, :select => "name, website, city", :limit => 1)

...or...

l = Location.find_by_sql(:conditions => ["SELECT name, website, city FROM locations WHERE id = ? LIMIT 1", id])

This reference doc gives you the entire list of options you can use with .find, including how to limit by number, id, or any other arbitrary column/constraint.

In Rails 3 w/ActiveRecord Query Interface

l = Location.where(["id = ?", id]).select("name, website, city").first

Ref: Active Record Query Interface

You can also swap the order of these chained calls, doing .select(...).where(...).first - all these calls do is construct the SQL query and then send it off.

You are having this problem because you are attempting to console log app.address() before the connection has been made. You just have to be sure to console log after the connection is made, i.e. in a callback or after an event signaling that the connection has been made.

Fortunately, the 'listening' event is emitted by the server after the connection is made so just do this:

var express = require('express');
var http = require('http');

var app = express();
var server = http.createServer(app);

app.get('/', function(req, res) {
    res.send("Hello World!");
});

server.listen(3000, 'localhost');
server.on('listening', function() {
    console.log('Express server started on port %s at %s', server.address().port, server.address().address);
});

This works just fine in nodejs v0.6+ and Express v3.0+.

Starting with 1.6.4, Arduino IDE can be used to program and upload the NodeMCU board by installing the ESP8266 third-party platform package (refer https://github.com/esp8266/Arduino):

• Start Arduino, go to File > Preferences
• Add the following link to the Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json and press OK button
• Click Tools > Boards menu > Boards Manager, search for ESP8266 and install ESP8266 platform from ESP8266 community (and don't forget to select your ESP8266 boards from Tools > Boards menu after installation)

To install additional ESP8266WiFi library:

• Click Sketch > Include Library > Manage Libraries, search for ESP8266WiFi and then install with the latest version.

After above steps, you should compile the sketch normally.

 $('div#imageContainer').click(function () {
      $('div#imageContainerimg').attr('src', 'YOUR NEW IMAGE URL HERE'); 
});

Go to "Settings" -> "Password & security" -> "Privacy" -> "Special app access" -> "Device admin apps" and select the account which you want to uninstall.

Or Simply

go to setting -> Then search for Device admin apps -> click and select the account which you want to uninstall.

Prototype is the template of the class; which applies to all future instances of it. Whereas this is the particular instance of the object.

Unless I am greatly mistaken, the answer is, "No, there is no way."

The basic problem in situations like that is the fact that you are calling a MySQL function and you're not actually setting a value. CI escapes values so that you can do a clean insert but it does not test to see if those values happen to be calling functions like aes_encrypt, md5, or (in this case) now(). While in most situations this is wonderful, for those situations raw sql is the only recourse.

On a side, date('Y-m-d'); should work as a PHP version of NOW() for MySQL. (It won't work for all versions of SQL though).

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

I found a dirty trick but it works, you could use the hover function to get the value before change!

int rgb = new Color(r, g, b).getRGB();

did you try something like this? not tested...

$(document).ready(function(){
    $('.ajaxAnchor').on('click', function (event){ 
        event.preventDefault(); 
        var url = $(this).attr('href');
        $.get(url, function(data) {
            $('section.center').html(data);
            var shortened = url.substring(0,url.length - 5);
            window.location.hash = shortened;
        });
    });
});

Simply set Apache to listen on a different port. This can be done by clicking on the "Config" button on the same line as the "Apache" module, select the "httpd.conf" file in the dropdown, then change the "Listen 80" line to "Listen 8080". Save the file and close it.

Now it avoids Port 80 and uses Port 8080 instead without issue. The only additional thing you need to do is make sure to put localhost:8080 in the browser so the browser knows to look on Port 8080. Otherwise it defaults to Port 80 and won't find your local site.

Find elements:

var elements = document.getElementsByClassName('widget hover');

Since elements is a live array and reflects all dom changes you can remove all hover classes with a simple while loop:

while(elements.length > 0){
    elements[0].classList.remove('hover');
}

after the update to the last versión i had this problem with all my projects, but it was solved just adding again the library reference:

if you don´t have the library into your workspace in Eclipse you can add it with: File -> Import -> Existing Android Code Into Workspace -> browse and navigate to google-play-services_lib project lib, (android-sdk/extras/google/google_play_services/libproject).

then deleting /bin and /gen folders of my project (something similar to the clean option) and building my project again.

I seem to be getting some joy with

git rev-list branch...master

The last line you get is the first commit on the branch, so then it's a matter of getting the parent of that. So

git rev-list -1 `git rev-list branch...master | tail -1`^

Seems to work for me and doesn't need diffs and so on (which is helpful as we don't have that version of diff)

Correction: This doesn't work if you are on the master branch, but I'm doing this in a script so that's less of an issue

Try this from different folder:

sudo tar -cvjSf folder.tar.bz2 folder/*

There are two steps to fix this.

First edit phpMyAdmin/libraries/DatabaseInterface.class.php

Change:

    if (PMA_MYSQL_INT_VERSION >  50503) {
        $default_charset = 'utf8mb4';
        $default_collation = 'utf8mb4_general_ci';
    } else {
        $default_charset = 'utf8';
        $default_collation = 'utf8_general_ci';
    }

To:

    //if (PMA_MYSQL_INT_VERSION >  50503) {
    //    $default_charset = 'utf8mb4';
    //    $default_collation = 'utf8mb4_general_ci';
    //} else {
        $default_charset = 'utf8';
        $default_collation = 'utf8_general_ci';
    //}

Then delete this cookie from your browser "pma_collation_connection".
Or delete all Cookies.

Then restart your phpMyAdmin.

(It would be nice if phpMyAdmin allowed you to set the charset and collation per server in the config.inc.php)

Bill Horst's - Converting SQL to LINQ is a very good resource for this task (as well as LINQPad).

LINQ Tools has a decent list of tools as well but I do not believe there is anything else out there that can do what Linqer did.

Generally speaking, LINQ is a higher-level querying language than SQL which can cause translation loss when trying to convert SQL to LINQ. For one, LINQ emits shaped results and SQL flat result sets. The issue here is that an automatic translation from SQL to LINQ will often have to perform more transliteration than translation - generating examples of how NOT to write LINQ queries. For this reason, there are few (if any) tools that will be able to reliably convert SQL to LINQ. Analogous to learning C# 4 by first converting VB6 to C# 4 and then studying the resulting conversion.

var trim = your_string.replace(/^\s+|\s+$/g, '');

I know that this is not a technical solution but I had my iphone connected with the computer by cable and disconnecting the device from the computer and connecting it again (by cable again) worked for me as I could not solved it with the solutions that are provided before.

If you are using Android Studio 2.0 Beta, this issue might appear (more likely if you are working on NTFS filesystem) and it seems like the "Instant Run" is the culprit. Search for "Instant Run" in settings and uncheck the box.

I have filed an issue on the bug tracker.

Reflection is slower, but works for a situation when you want to know whether that is of type Dog or a Cat and not an instance of Animal. So you'd do something like:

if(null != items.elementAt(1) && items.elementAt(1).getClass().toString().equals("Cat"))
{
//do whatever with cat.. not any other instance of animal.. eg. hideClaws();
}

Not saying the answer above does not work, except the null checking part is necessary.

Another way to answer that is use generics and you are guaranteed to have Double as any element of items.

List<Double> items = new ArrayList<Double>();

As the documentation says, this method call returns "a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive)". This means that you will get numbers from 0 to 9 in your case. So you've done everything correctly by adding one to that number.

Generally speaking, if you need to generate numbers from min to max (including both), you write

random.nextInt(max - min + 1) + min

You can get html element tag name on whole page.

You could use:

        $('body').contents().on("click",function () {
          var string = this.tagName;
          alert(string);
         });

Images have display: inline by default.
You might want to put the image inside the paragraph.
<p><img /></p>

Thank you so much for this. I have modified it to work with Windows. I have also put a low timeout so, the IP's that have no return will not sit and wait for 5 seconds each. This is from hochl source code.

import subprocess
import os
with open(os.devnull, "wb") as limbo:
        for n in xrange(200, 240):
                ip="10.2.7.{0}".format(n)
                result=subprocess.Popen(["ping", "-n", "1", "-w", "200", ip],
                        stdout=limbo, stderr=limbo).wait()
                if result:
                        print ip, "inactive"
                else:
                        print ip, "active"

Just change the ip= for your scheme and the xrange for the hosts.

I am always used DateDiff(day,date1,date2) to compare two date.

Checkout following example. Just copy that and run in Ms sql server. Also, try with change date by 31 dec to 30 dec and check result

BEGIN

declare @firstDate datetime
declare @secondDate datetime


declare @chkDay int

set @firstDate ='2010-12-31 15:13:48.593'
set @secondDate ='2010-12-31 00:00:00.000'

set @chkDay=Datediff(day,@firstDate ,@secondDate )

if @chkDay=0
    Begin
        Print 'Date is Same'
    end
else
    Begin
        Print 'Date is not Same'
    end
End

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

can also appear if:

struct foo {   int x, int y, int z }foo; 

foo.x=12

instead of

struct foo {   int x; int y; int z; }foo; 

foo.x=12

I have gone through this question earlier but did not found complete gui based solution.Today I got a GUI based solution provided by spring.

In short we need to do only that much:

1.Install plugin in eclipse from update site: site link

2.Import project as gradle and browse the .gradle file..that's it.

Complete documentation is here

A click is an event; you can't query an element and ask it whether it's being clicked on or not. How about this:

jQuery('#id').click(function () {
   // do some stuff
});

Then if you really wanted to, you could just have a loop that executes every few seconds with your // run function..

The cause of your problems is that you are trying to do a cross-domain call and it fails.

If you're doing localhost development you can make cross-domain calls - I do it all the time.

For Firefox, you have to enable it in your config settings

signed.applets.codebase_principal_support = true

Then add something like this to your XHR open code:

  if (isLocalHost()){
    if (typeof(netscape) != 'undefined' && typeof(netscape.security) != 'undefined'){
      netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    }
  }

For IE, if I remember right, all you have to do is enable the browser's Security setting under "Miscellaneous → Access data sources across domains" to get it to work with ActiveX XHRs.

IE8 and above also added cross-domain capabilities to the native XmlHttpRequest objects, but I haven't played with those yet.

in case you don't want to use Ajax , and want your page to reload .

<?php
if(isset($_POST['user']) {
echo $_POST["user"]; //just an example of processing
}    
?>

First remove super.onBackPressed(); from onbackPressed() method than and below code:

@Override
public void onBackPressed() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Are you sure you want to exit?")
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    MyActivity.this.finish();
               }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
               }
           });
    AlertDialog alert = builder.create();
    alert.show();

}

public void convert(int s)

There is a lot of answers, but I decided to add my own, because it's little different. It's based on OOP ;)

I created class DirectoryCleaner, which help me each time when I need to clean some directory.

public class DirectoryCleaner {
    private final File mFile;

    public DirectoryCleaner(File file) {
        mFile = file;
    }

    public void clean() {
        if (null == mFile || !mFile.exists() || !mFile.isDirectory()) return;
        for (File file : mFile.listFiles()) {
            delete(file);
        }
    }

    private void delete(File file) {
        if (file.isDirectory()) {
            for (File child : file.listFiles()) {
                delete(child);
            }
        }
        file.delete();

    }
}

It can be used to solve this problem in next way:

File dir = new File(Environment.getExternalStorageDirectory(), "your_directory_name");
new DirectoryCleaner(dir).clean();
dir.delete();

    public subtract(ts: TimeSpan): TimeSpan {
        const result = this._millis - ts.totalMilliseconds;
        return new TimeSpan(result);
    }
}

How to use

Create a new TimeSpan object

    const ts = TimeSpan.zero;

    const milliseconds = 10000; // 1 second

    // by using the constructor
    const ts1 = new TimeSpan(milliseconds);

    // or as an alternative you can use the static factory method
    const ts2 = TimeSpan.fromMilliseconds(milliseconds);

    const seconds = 86400; // 1 day
    const ts = TimeSpan.fromSeconds(seconds);

    const minutes = 1440; // 1 day
    const ts = TimeSpan.fromMinutes(minutes);

    const hours = 24; // 1 day
    const ts = TimeSpan.fromHours(hours);

    const days = 1; // 1 day
    const ts = TimeSpan.fromDays(days);

    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const ts = TimeSpan.fromTime(hours, minutes, seconds);

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime(days, hours, minutes, seconds, milliseconds);

    const ts = TimeSpan.maxValue;

    const ts = TimeSpan.minValue;

    const ts = TimeSpan.minValue;

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.add(ts2);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.subtract(ts2);

    console.log(ts.days);               // 0
    console.log(ts.hours);              // 23
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime2(days, hours, minutes, seconds, milliseconds);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 1
    console.log(ts.seconds);            // 1
    console.log(ts.milliseconds);           // 1

    console.log(ts.totalDays)           // 1.0423726967592593;
    console.log(ts.totalHours)          // 25.016944722222224;
    console.log(ts.totalMinutes)            // 1501.0166833333333;
    console.log(ts.totalSeconds)            // 90061.001;
    console.log(ts.totalMilliseconds);      // 90061001;

You have some very good answers here, but I'm to me, it looks like a case of "when all you know is a hammer"...

The simplest answer of to why there is no standard way to initialise a static map, is there is no good reason to ever use a static map...

A map is a structure designed for fast lookup, of an unknown set of elements. If you know the elements before hand, simply use a C-array. Enter the values in a sorted manner, or run sort on them, if you can't do this. You can then get log(n) performance by using the stl::functions to loop-up entries, lower_bound/upper_bound. When I have tested this previously they normally perform at least 4 times faster than a map.

The advantages are many fold... - faster performance (*4, I've measured on many CPU's types, it's always around 4) - simpler debugging. It's just easier to see what's going on with a linear layout. - Trivial implementations of copy operations, should that become necessary. - It allocates no memory at run time, so will never throw an exception. - It's a standard interface, and so is very easy to share across, DLL's, or languages, etc.

I could go on, but if you want more, why not look at Stroustrup's many blogs on the subject.

Yes You can have more than one Class in one .Java file . But You have make one of them Public . and save .java file with same name as name of public class. when you will compile that .java file than you will get Separate .class files for each class defined in .java file .

Apart from this there are too many method for defining more than one class in one .java file .

1. use concept of Inner Classes.
2. Use Concept of Anonymous Classes .

Write the root logger as below for logging on both console and FILE

log4j.rootLogger=ERROR,console,FILE

And write the respective definitions like Target, Layout, and ConversionPattern (MaxFileSize for file etc).

some resources:

1. ELF for the ARM architecture
   http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044d/IHI0044D_aaelf.pdf
2. ELF from wiki
   http://en.wikipedia.org/wiki/Executable_and_Linkable_Format

ELF format is generally the default output of compiling. if you use GNU tool chains, you can translate it to binary format by using objcopy, such as:

  arm-elf-objcopy -O binary [elf-input-file] [binary-output-file]

or using fromELF utility(built in most IDEs such as ADS though):

 fromelf -bin -o [binary-output-file] [elf-input-file]

Also from Java 8 you can write Dan Cruz answer as:

Thread t = new Thread(()->{
            System.out.println("Sleeping ...");
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                System.out.println("Interrupted.");
            }
            System.out.println("Throwing exception ...");
            throw new RuntimeException(); });


t.setUncaughtExceptionHandler((th, ex)-> log(String.format("Exception in thread %d id: %s", th.getId(), ex)));
t.start();

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

If your blog outputs an RSS feed you can use Facebook's "RSS Graffiti" application to post that feed to your wall in Facebook. There are other RSS Facebook apps as well; just search "Facebook for RSS apps"...

If you look deeper into the other uses of size you can see that you can actually get a vector of the size of each dimension. This link shows you the documentation:

www.mathworks.com/access/helpdesk/help/techdoc/ref/size.html

After getting the size vector, iterate over that vector. Something like this (pardon my syntax since I have not used Matlab since college):

d = size(m);
dims = ndims(m);
for dimNumber = 1:dims
   for i = 1:d[dimNumber]
      ...

Make this into actual Matlab-legal syntax, and I think it would do what you want.

Also, you should be able to do Linear Indexing as described here.

next and break seem to do the correct thing in this simplified example!

class Bar
  def self.do_things
      Foo.some_method(1..10) do |x|
            next if x == 2
            break if x == 9
            print "#{x} "
      end
  end
end

class Foo
    def self.some_method(targets, &block)
      targets.each do |target|
        begin
          r = yield(target)
        rescue  => x
          puts "rescue #{x}"
        end
     end
   end
end

Bar.do_things

output: 1 3 4 5 6 7 8

To see what was changed in a file in the last commit:

git diff HEAD~1 path/to/file

You can change the number (~1) to the n-th commit which you want to diff with.

Setup:

My OS windows 8 64bit
Eclipse version Standard/SDK Kepler Service Release 2
My JDK is jdk-8u5-windows-i586
My JRE is jre-8u5-windows-i586

This how I overcome my error.

At the very first my Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") also didn't work. Then I login to this website and downloaded the UCanAccess 2.0.8 zip (as Mr.Gord Thompson said) file and unzip it.

Then you will also able to find these *.jar files in that unzip folder:

ucanaccess-2.0.8.jar
commons-lang-2.6.jar
commons-logging-1.1.1.jar
hsqldb.jar
jackcess-2.0.4.jar

Then what I did was I copied all these 5 files and paste them in these 2 locations:

C:\Program Files (x86)\eclipse\lib
C:\Program Files (x86)\eclipse\lib\ext

(I did that funny thing becoz I was unable to import these libraries to my project)

Then I reopen the eclipse with my project.then I see all that *.jar files in my project's JRE System Library folder.

Finally my code works.

public static void main(String[] args) 
{

    try
    {

        Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\Hasith\\Documents\\JavaDatabase1.mdb");
        Statement stment = conn.createStatement();
        String qry = "SELECT * FROM Table1";

        ResultSet rs = stment.executeQuery(qry);
        while(rs.next())
        {
            String id    = rs.getString("ID") ;
            String fname = rs.getString("Nama");

            System.out.println(id + fname);
        }
    }
    catch(Exception err)
    {
        System.out.println(err);
    }


    //System.out.println("Hasith Sithila");

}

You may need to handle javax.persistence.RollbackException

If you have an option of file formats I suggest using .ini and Python's ConfigParser as mentioned. If you need compatibility with Java .properties files I have written a library for it called jprops. We were using pyjavaproperties, but after encountering various limitations I ended up implementing my own. It has full support for the .properties format, including unicode support and better support for escape sequences. Jprops can also parse any file-like object while pyjavaproperties only works with real files on disk.

Here's how to do it with list comprehension:

a = (1, 2, 3)
b = (4, 5, 6)
[print('f:', i, '; b', j) for i, j in zip(a, b)]

prints:

f: 1 ; b 4
f: 2 ; b 5
f: 3 ; b 6

To check if a Path exists to a directory, use this one:

$pathToDirectory = "c:\program files\blahblah\"
if (![System.IO.Directory]::Exists($pathToDirectory))
{
 mkdir $path1
}

To check if a Path to a file exists use what @Mathias suggested:

[System.IO.File]::Exists($pathToAFile)

Human readable: (eg. can be log to text file..)

print_r( $arr_name , TRUE);

You just need to add disabled as option attribute

<option disabled>select one option</option>

I had to do the same for one of my projects and I ended up writing my own as well. I called it HorzListView is now part of my open source Aniqroid library.

http://aniqroid.sileria.com/doc/api/ (Look for downloads at the bottom or use google code project to see more download options: http://code.google.com/p/aniqroid/downloads/list)

The class documentation is here: http://aniqroid.sileria.com/doc/api/com/sileria/android/view/HorzListView.html

Below is a "standard recursive answer", similar to the other similar answer https://stackoverflow.com/a/23743696/711085 . (We don't realistically have to worry about running out of stack space since there's no way we could process all N! permutations.)

It visits every element in turn, and either takes it or leaves it (we can directly see the 2^N cardinality from this algorithm).

def combs(xs, i=0):
    if i==len(xs):
        yield ()
        return
    for c in combs(xs,i+1):
        yield c
        yield c+(xs[i],)

Demo:

>>> list( combs(range(5)) )
[(), (0,), (1,), (1, 0), (2,), (2, 0), (2, 1), (2, 1, 0), (3,), (3, 0), (3, 1), (3, 1, 0), (3, 2), (3, 2, 0), (3, 2, 1), (3, 2, 1, 0), (4,), (4, 0), (4, 1), (4, 1, 0), (4, 2), (4, 2, 0), (4, 2, 1), (4, 2, 1, 0), (4, 3), (4, 3, 0), (4, 3, 1), (4, 3, 1, 0), (4, 3, 2), (4, 3, 2, 0), (4, 3, 2, 1), (4, 3, 2, 1, 0)]

>>> list(sorted( combs(range(5)), key=len))
[(), 
 (0,), (1,), (2,), (3,), (4,), 
 (1, 0), (2, 0), (2, 1), (3, 0), (3, 1), (3, 2), (4, 0), (4, 1), (4, 2), (4, 3), 
 (2, 1, 0), (3, 1, 0), (3, 2, 0), (3, 2, 1), (4, 1, 0), (4, 2, 0), (4, 2, 1), (4, 3, 0), (4, 3, 1), (4, 3, 2), 
 (3, 2, 1, 0), (4, 2, 1, 0), (4, 3, 1, 0), (4, 3, 2, 0), (4, 3, 2, 1), 
 (4, 3, 2, 1, 0)]

>>> len(set(combs(range(5))))
32

You can set the figure size if you explicitly create the figure with

plt.figure(figsize=(3,4))

You need to set figure size before calling plt.plot() To change the format of the saved figure just change the extension in the file name. However, I don't know if any of matplotlib backends support tiff

You need to set the Height property of the RowTemplate:

var dgv = new DataGridView();
dgv.RowTemplate.Height = 30;

If you don't want to use a library, this should cover most/all of the same form element types.

function serialize(form) {
  if (!form || !form.elements) return;

  var serial = [], i, j, first;
  var add = function (name, value) {
    serial.push(encodeURIComponent(name) + '=' + encodeURIComponent(value));
  }

  var elems = form.elements;
  for (i = 0; i < elems.length; i += 1, first = false) {
    if (elems[i].name.length > 0) { /* don't include unnamed elements */
      switch (elems[i].type) {
        case 'select-one': first = true;
        case 'select-multiple':
          for (j = 0; j < elems[i].options.length; j += 1)
            if (elems[i].options[j].selected) {
              add(elems[i].name, elems[i].options[j].value);
              if (first) break; /* stop searching for select-one */
            }
          break;
        case 'checkbox':
        case 'radio': if (!elems[i].checked) break; /* else continue */
        default: add(elems[i].name, elems[i].value); break;
      }
    }
  }

  return serial.join('&');
}

This works for me.

• Open Task Manager
• Select services tab
• Select the service with the issue
• Right click and select "Go to details"
• Right click on the service and select "End process tree"

End process tree will end the process and all the processes created by the process.

Then, you can reinstall the service.

I was using reactive forms and ran into similar problems. What helped me was to make sure that I set up a corresponding FormGroup in the class. Something like this:

myFormGroup: FormGroup = this.builder.group({
    dob: ['', Validators.required]
});

Jenkins is a service account, it doesn't have a shell by design. It is generally accepted that service accounts. shouldn't be able to log in interactively.

To resolve "Jenkins Host key verification failed", do the following steps. I have used mercurial with jenkins.

1)Execute following commands on terminal

             $ sudo su -s /bin/bash jenkins

provide password

2)Generate public private key using the following command:

              ssh-keygen

you can see output as ::

Generating public/private rsa key pair. 
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 

3)Press Enter --> Do not give any passphrase--> press enter

             Key has been generated

4) go to --> cat /var/lib/jenkins/.ssh/id_rsa.pub

5) Copy key from id_rsa.pub

6)Exit from bash

7) ssh@yourrepository

8) vi .ssh/authorized_keys

9) Paste the key

10) exit

11)Manually login to mercurial server

Note: Pls do manually login otherwise jenkins will again give error "host verification failed"

12)once manually done, Now go to Jenkins and give build

Enjoy!!!

Good Luck

This may not be from the script end but you can use the below css and add this class to the div. This will truncate the text and also show full text on mouseover. You can add a more text and add a angular click hadler to change the class of div on cli

.ellipseContent {
    overflow: hidden;
    white-space: nowrap;
    -ms-text-overflow: ellipsis;
    text-overflow: ellipsis;
}

    .ellipseContent:hover {
        overflow: visible;
        white-space: normal;
    }

I would like to offer a minor improvement on the last loop answer given in the previous post (that post is correct and should still be accepted). The implicit assumption made when labeling the last example is that plt.label(LIST) puts label number X in LIST with the line corresponding to the Xth time plot was called. I have run into problems with this approach before. The recommended way to build legends and customize their labels per matplotlibs documentation ( http://matplotlib.org/users/legend_guide.html#adjusting-the-order-of-legend-item) is to have a warm feeling that the labels go along with the exact plots you think they do:

...
# Plot several different functions...
labels = []

The most convenient implementation. Here you need two methods, in order to return directly to the object of your class, not UIView.

1. viewId marked as a class, allowing override
2. Your .xib can contain more than one view of the top level, this situation is also handled correctly.

extension UIView {

class var viewId: String {
    return String(describing: self)
}

static func instance(from bundle: Bundle? = nil, nibName: String? = nil,
                    owner: Any? = nil, options: [AnyHashable : Any]? = nil) -> Self? {

    return instancePrivate(from: bundle ?? Bundle.main,
                           nibName: nibName ?? viewId,
                           owner: owner,
                           options: options)
}

private static func instancePrivate<T: UIView>(from bundle: Bundle, nibName: String,
                                              owner: Any?, options: [AnyHashable : Any]?) -> T? {

    guard
        let views = bundle.loadNibNamed(nibName, owner: owner, options: options),
        let view = views.first(where: { $0 is T }) as? T else { return nil }

    return view
}
}

Example:

guard let customView = CustomView.instance() else { return }

//Here customView has CustomView class type, not UIView.
print(customView is CustomView) // true

Pooja Mane's answer worked for me, but I had to put the client_max_body_size variable inside of http section.

If you're willing to go the way of the preprocessor abuse, Boost.Preprocessor can help you.

    #include <boost/preprocessor/seq/for_each.hpp>

    #define CASE_case(ign, ign2, n) case n:

    #define CASES(seq) \
        BOOST_PP_SEQ_FOR_EACH(CASE_case, ~, seq)

    CASES((1)(3)(15)(13))

Running this through gcc with -E -P to only run the preprocessor, the expansion of CASES gives:

    case 1: case 3: case 15: case 13:

Note that this probably wouldn't pass a code review (wouldn't where I work!) so I recommend it be constrained to personal use.

It should also be possible to create a CASE_RANGE(1,5) macro to expand to

    case 1: case 2: case 3: case 4: case 5:

for you as well.

mvnrepository.com isn't a repository. It's a search engine. It might or might not tell you what repository it found stuff in if it's not central; since you didn't post an example, I can't help you read the output.

As long as you do not use 1.4 version, you can use explicit annotation:

example:

@Query("select count(e) from Product e where e.area.code = ?1")
long countByAreaCode(String code);

You can do it via cmd.

For Apache

Open cmd in administrator mode. Change directory to C:/xampp/apache/bin. Run the command as httpd.exe -k install. Your Apache server service will be installed. You can start it from services.

For MySQL

Change directory to C:/xampp/mysql/bin. Run the command as mysqld --install. Your MySQL service will be installed. You can start it from services.

Note: Make sure the selected Apache and MySQL services are set to start automatically.

You're done. There isn't any need to launch the XAMPP control panel

You can try using one of their tools: http://www.ws-i.org/deliverables/workinggroup.aspx?wg=testingtools

These will check both WSDL validity and Basic Profile 1.1 compliance.

As soon as question is about dynamic array you may want not just to create array with variable size, but also to change it's size during runtime. Here is an example with memcpy, you can use memcpy_s or std::copy as well. Depending on compiler, <memory.h> or <string.h> may be required. When using this functions you allocate new memory region, copy values of original memory regions to it and then release them.

//    create desired array dynamically
size_t length;
length = 100; //for example
int *array = new int[length];

//   now let's change is's size - e.g. add 50 new elements
size_t added = 50;
int *added_array = new int[added];

/*   
somehow set values to given arrays
*/ 

//    add elements to array
int* temp = new int[length + added];
memcpy(temp, array, length * sizeof(int));
memcpy(temp + length, added_array, added * sizeof(int));
delete[] array;
array = temp;

You may use constant 4 instead of sizeof(int).

You can do it without any interruption, with the new (Git 2.0 Q2 2014) setting gc.autodetach.

See commit 4c4ac4d and commit 9f673f9 (Nguy?n Thái Ng?c Duy, aka pclouds):

gc --auto takes time and can block the user temporarily (but not any less annoyingly).
Make it run in background on systems that support it.
The only thing lost with running in background is printouts. But gc output is not really interesting.
You can keep it in foreground by changing gc.autodetach.

Since that 2.0 release, there was a bug though: git 2.7 (Q4 2015) will make sure to not lose the error message.
See commit 329e6e8 (19 Sep 2015) by Nguy?n Thái Ng?c Duy (pclouds).
^{(Merged by Junio C Hamano -- gitster -- in commit 076c827, 15 Oct 2015)}

gc: save log from daemonized gc --auto and print it next time

While commit 9f673f9 (gc: config option for running --auto in background - 2014-02-08) helps reduce some complaints about 'gc --auto' hogging the terminal, it creates another set of problems.

The latest in this set is, as the result of daemonizing, stderr is closed and all warnings are lost. This warning at the end of cmd_gc() is particularly important because it tells the user how to avoid "gc --auto" running repeatedly.
Because stderr is closed, the user does not know, naturally they complain about 'gc --auto' wasting CPU.

Daemonized gc now saves stderr to $GIT_DIR/gc.log.
Following gc --auto will not run and gc.log printed out until the user removes gc.log.

For the cloning process, the object can be converted to the byte array first and then converted back to the object.

public static class Extentions
{
    public static T Clone<T>(this T obj)
    {
        byte[] buffer = BinarySerialize(obj);
        return (T)BinaryDeserialize(buffer);
    }

    public static byte[] BinarySerialize(object obj)
    {
        using (var stream = new MemoryStream())
        {
            var formatter = new BinaryFormatter(); 
            formatter.Serialize(stream, obj); 
            return stream.ToArray();
        }
    }

    public static object BinaryDeserialize(byte[] buffer)
    {
        using (var stream = new MemoryStream(buffer))
        {
           var formatter = new BinaryFormatter(); 
           return formatter.Deserialize(stream);
        }
    }
}

The object must be serialized for the serialization process.

[Serializable]
public class MyObject
{
    public string Name  { get; set; }
}

Usage:

MyObject myObj  = GetMyObj();
MyObject newObj = myObj.Clone();

I prefer:

$qb->andWhere($qb->expr()->in('t.user_role_id', [
    User::USER_ROLE_ID_ADVERTISER,
    User::USER_ROLE_ID_MANAGER,
]));

Try this :

use Illuminate\Support\Facades\Request;
public function add_question(Request $request)
{
    return $request->all();
}

Maybe a little late, but I want to add my 2 cents.

if your string ALWAYS represents a number, with possible leading zeros, you can simply cast the string to a number by using the '+' operator.

e.g.

x= "00005";
alert(typeof x); //"string"
alert(x);// "00005"

x = +x ; //or x= +"00005"; //do NOT confuse with x+=x, which will only concatenate the value
alert(typeof x); //number , voila!
alert(x); // 5 (as number)

if your string doesn't represent a number and you only need to remove the 0's use the other solutions, but if you only need them as number, this is the shortest way.

and FYI you can do the opposite, force numbers to act as strings if you concatenate an empty string to them, like:

x = 5;
alert(typeof x); //number
x = x+"";
alert(typeof x); //string

hope it helps somebody

I haven't seen anybody use this method, but it worked for me and is short and sweet:

int num = 5542;
String number = String.valueOf(num);
for(int i = 0; i < number.length(); i++) {
    int j = Character.digit(number.charAt(i), 10);
    System.out.println("digit: " + j);
}

This will output:

digit: 5
digit: 5
digit: 4
digit: 2

You assign to big and small before the array is initialized, i.e., big and small assume the value of whatever is on the stack at this point. As they are just plain value types and no references, they won't assume a new value once values[0] is written to via cin >>.

Just move the assignment after your first loop and it should be fine.

UPDATE chart.js 2.1 and above

var chart = new Chart(ctx, {
    ...
    options:{
        scales:{
            xAxes: [{
                display: false //this will remove all the x-axis grid lines
            }]
        }
    }
});


var chart = new Chart(ctx, {
    ...
    options: {
        scales: {
            xAxes: [{
                ticks: {
                    display: false //this will remove only the label
                }
            }]
        }
    }
});

Reference: chart.js documentation

Old answer (written when the current version was 1.0 beta) just for reference below:

To avoid displaying labels in chart.js you have to set scaleShowLabels : false and also avoid to pass the labels:

<script>
    var options = {
        ...
        scaleShowLabels : false
    };
    var lineChartData = {
        //COMMENT THIS LINE TO AVOID DISPLAYING THE LABELS
        //labels : ["1","2","3","4","5","6","7"],
        ... 
    }
    ...
</script>

You are getting a keySet iterator on the HashMap and expecting to iterate over entries.

Correct code:

    HashMap hm = new HashMap();

    hm.put(0, "zero");
    hm.put(1, "one");

    //Here we get the keyset iterator not the Entry iterator
    Iterator iter = (Iterator) hm.keySet().iterator();

    while(iter.hasNext()) {

        //iterator's next() return an Integer that is the key
        Integer key = (Integer) iter.next();
        //already have the key, now get the value using get() method
        System.out.println(key + " - " + hm.get(key));

    }

Iterating over a HashMap using EntrySet:

     HashMap hm = new HashMap();
     hm.put(0, "zero");
     hm.put(1, "one");
     //Here we get the iterator on the entrySet
     Iterator iter = (Iterator) hm.entrySet().iterator();


     //Traversing using iterator on entry set  
     while (iter.hasNext()) {  
         Entry<Integer,String> entry = (Entry<Integer,String>) iter.next();  
         System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
     }  

     System.out.println();


    //Iterating using for-each construct on Entry Set
    Set<Entry<Integer, String>> entrySet = hm.entrySet();
    for (Entry<Integer, String> entry : entrySet) {  
        System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
    }           

Look at the section -Traversing Through a HashMap in the below link. java-collection-internal-hashmap and Traversing through HashMap

Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

select * from tab
where DateCol between adddate(now(),-7) and now() 

It is actually very easy. But there is no way you can achieve it directly. You need to select a service side technology. You can use anything for this part. And this is what we call a RESTful API or a SOAP API. It depends on you what to select. I have done many project with both. I would prefer REST. So what will happen you will have some scripts in your web server, and you know the URLs. For example we need to make a user registration. And for this we have

mydomain.com/v1/userregister.php

Now from the android side you will send an HTTP request to the above URL. And the above URL will handle the User Registration and will give you a response that whether the operation succeed or not.

For a complete detailed explanation of the above concept. You can visit the following link.

**Android MySQL Tutorial to Perform CRUD Operation**

If you want to stop every movie tag in your page from playing, this little snippet of jQuery will help you:

$("video").each(function () { this.pause() });

As everyone has said, you definitely need the key. There's no workaround for that. However, you might be surprised at how good the data recovery software can be, and how long the key may linger on your systems -- it's a tiny, tiny file, after all, and may not yet be overwritten. I was pleasantly surprised on both counts.

I develop on an OSX machine. I unintentionally deleted my app key around 6 weeks ago. When I tried to update, I realized my schoolboy error. I tried all the recovery tools I could find for OSX, but none could find the file -- not because it wasn't there, but because these tools are optimized to find the sorts of files the majority of users want back (photos, Word docs, etc.). They're definitely not looking for a 1KB file with an unusual file signature.

Now this next part is going to sound like a plug, but it isn't -- I don't have any connection to the developers:

The only recover tool I found that worked was one called Data Rescue by Prosoft Engineering (which I believe works for other files systems as well -- not just HFS+). It worked because it has a feature which allows you to train it to look for any file type -- even an Android key. You give it several examples. (I generated a few keys, filling in the data fields in as like manner as possible to the original). You then tell it to "deep search". If you're lucky, you'll get your key back in the "custom files" section.

For me, it was a life saver.

It's $100 to purchase, so it's not cheap, but it's worth it if you've got a mass of users and no further means of feeding them updates.

I believe they allow you 1 free file recovery in demo mode, but, unfortunately, in my case, I had several keys and could not tell which one was the one I needed without recovering them all (file names are not preserved on HFS+).

Try it first in demo mode, you may get lucky and be able to recover the key without paying anything.

May this message help someone. It's a sickening feeling, I know, but there may be relief.

For immutable data types:

l = [0] * 100
# [0, 0, 0, 0, 0, ...]

l = ['foo'] * 100
# ['foo', 'foo', 'foo', 'foo', ...]

For values that are stored by reference and you may wish to modify later (like sub-lists, or dicts):

l = [{} for x in range(100)]

(The reason why the first method is only a good idea for constant values, like ints or strings, is because only a shallow copy is does when using the <list>*<number> syntax, and thus if you did something like [{}]*100, you'd end up with 100 references to the same dictionary - so changing one of them would change them all. Since ints and strings are immutable, this isn't a problem for them.)

If you want to add to an existing list, you can use the extend() method of that list (in conjunction with the generation of a list of things to add via the above techniques):

a = [1,2,3]
b = [4,5,6]
a.extend(b)
# a is now [1,2,3,4,5,6]

I had to uncomment extension=openssl in php.ini file for everything to work!

UIAlertViews use a delegate to communicate with you, the client.

You add a second button, and you create an object to receive the delegate messages from the view:

class LogInErrorDelegate : UIAlertViewDelegate {

    init {}

    // not sure of the prototype of this, you should look it up
    func alertView(view :UIAlertView, clickedButtonAtIndex :Integer) -> Void {
        switch clickedButtonAtIndex {
            case 0: 
               userClickedOK() // er something
            case 1:
               userClickedRetry()
              /* Don't use "retry" as a function name, it's a reserved word */

            default:
               userClickedRetry()
        }
    }

    /* implement rest of the delegate */
}
logInErrorAlert.addButtonWithTitle("Retry")

var myErrorDelegate = LogInErrorDelegate()
logInErrorAlert.delegate = myErrorDelegate

Though it's probably suggested to get some heavier validation via JS or on the server, HTML5 does support this via the pattern attribute.

<input type= "text" name= "name" pattern= "[0-9]"  title= "Title"/>

Using some ES6 / ES2015:

If you don't like to create an extra function and remove the items 'inline'.

Object.keys(obj).forEach(k => (!obj[k] && obj[k] !== undefined) && delete obj[k]);

jsbin

Same, written as a function.

const removeEmpty = (obj) => {
  Object.keys(obj).forEach((k) => (!obj[k] && obj[k] !== undefined) && delete obj[k]);
  return obj;
};

jsbin

This function uses recursion to delete items from nested objects as well:

const removeEmpty = (obj) => {
  Object.keys(obj).forEach(k =>
    (obj[k] && typeof obj[k] === 'object') && removeEmpty(obj[k]) ||
    (!obj[k] && obj[k] !== undefined) && delete obj[k]
  );
  return obj;
};

jsbin

Same as function before but with ES7 / 2016 Object.entries:

const removeEmpty = (obj) => {
  Object.entries(obj).forEach(([key, val])  =>
    (val && typeof val === 'object') && removeEmpty(val) ||
    (val === null || val === "") && delete obj[key]
  );
  return obj;
};

Same as third example but in plain ES5:

function removeEmpty(obj) {
  Object.keys(obj).forEach(function(key) {
    (obj[key] && typeof obj[key] === 'object') && removeEmpty(obj[key]) ||
    (obj[key] === '' || obj[key] === null) && delete obj[key]
  });
  return obj;
};

jsbin

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

Must say I agree with that the most elegant solution to this is using boost::lexical_cast. You can then catch the bad_lexical_cast that might occure, and do something when it fails, instead of getting 0.0 which atof gives.

#include <boost/lexical_cast.hpp>
#include <string>

int main()
{
    std::string str = "3.14";
    double strVal;
    try {
        strVal = boost::lexical_cast<double>(str);
    } catch(bad_lexical_cast&) {
        //Do your errormagic
    }
    return 0;
}

If you just want to run a function for testing purposes, you can use the Immediate Window in Access.

Press Ctrl + G in the VBA editor to open it.

Then you can run your functions like this:

• ?YourFunction("parameter")
  (for functions with a return value - the return value is displayed in the Immediate Window)
• YourSub "parameter"
  (for subs without a return value, or for functions when you don't care about the return value)
• ?variable
  (to display the value of a variable)

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.
