Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

There are more than a few gateways out there, but I am not aware of a reliable gateway that is free. Most gateways like PayPal will provide you APIs that will allow you to process credit cards, as well as do things like void, charge, or refund.

The other thing you need to worry about is the coming of PCI compliance which basically says if you are not compliant, you (or the company you work for) will be liable by your Merchant Bank and/or Card Vendor for not being compliant by July of 2010. This will impose large fines on you and possibly revoke the ability for you to process credit cards.

All that being said companies like PayPal have a PHP SDK:

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_download_sdks

Authorize.Net:

http://developer.authorize.net/samplecode/

Those are two of the more popular ones for the United States.

For PCI Info see:

You should have access to the POST dictionary on the request object.

An abstract class is a class that you can't create an object from, so it is mostly used for inheriting from.(I am not sure if you can have static methods in it)

An abstract method is a method that the child class must override, it does not have a body, is marked abstract and only abstract classes can have those methods.

If you want to dubbel check the amount of cores you have on your machine to the number your java program is giving you.

In Linux terminal: lscpu

In Windows terminal (cmd): echo %NUMBER_OF_PROCESSORS%

In Mac terminal: sysctl -n hw.ncpu

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
    //get the natural page height -set it in variable above.

    currentHeight = $('#js_content_container').outerHeight();

    console.log("set current height on load = " + currentHeight)
    console.log("content height function (should be 374)  = " + contentHeight());   

});

Here is a more efficient way of fading out an element:

function fade(element) {
    var op = 1;  // initial opacity
    var timer = setInterval(function () {
        if (op <= 0.1){
            clearInterval(timer);
            element.style.display = 'none';
        }
        element.style.opacity = op;
        element.style.filter = 'alpha(opacity=' + op * 100 + ")";
        op -= op * 0.1;
    }, 50);
}

you can do the reverse for fade in

setInterval or setTimeout should not get a string as argument

google the evils of eval to know why

And here is a more efficient way of fading in an element.

function unfade(element) {
    var op = 0.1;  // initial opacity
    element.style.display = 'block';
    var timer = setInterval(function () {
        if (op >= 1){
            clearInterval(timer);
        }
        element.style.opacity = op;
        element.style.filter = 'alpha(opacity=' + op * 100 + ")";
        op += op * 0.1;
    }, 10);
}

Just copy paste below code!

This will print your current taxonomy name and description(optional)

<?php 
   $tax = $wp_query->get_queried_object();
   echo ''. $tax->name . '';
   echo "<br>";
   echo ''. $tax->description .''; 
?>

I had to install this other package:

sudo apt-get install libatlas-base-dev

Seems like it is a dependency for numpy but the pip or apt-get don't install it automatically for whatever reason.

A pitfall some might step into that is covered by this question but isn't addressed in the answers as it is slightly different in the code structure but returns the exact same error.

This error occurs when using bindActionCreators and not passing the dispatch function

Error Code

import someComponent from './someComponent'
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux'
import { someAction } from '../../../actions/someAction'

const mapStatToProps = (state) => {
    const { someState } = state.someState

    return {
        someState
    }
};

const mapDispatchToProps = (dispatch) => {
    return bindActionCreators({
        someAction
    });
};

export default connect(mapStatToProps, mapDispatchToProps)(someComponent)

Fixed Code

import someComponent from './someComponent'
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux'
import { someAction } from '../../../actions/someAction'

const mapStatToProps = (state) => {
    const { someState } = state.someState

    return {
        someState
    }
};

const mapDispatchToProps = (dispatch) => {
    return bindActionCreators({
        someAction
    }, dispatch);
};

export default connect(mapStatToProps, mapDispatchToProps)(someComponent)

The function dispatch was missing in the Error code

Some process is using the port 443, so you can change the port that is used by xampp, to be able to use it. For this job you have to do this:

1- Open httpd-ssl.conf in xampp\apache\conf\extra

2- Look for the line containing Listen 443

3- Change port number to anything you want. I use 4430. ex. Listen 4430.

4- Replace every 443 strings in that file with 4430 and save the file.

How to change max_connections

You can change max_connections while MySQL is running via SET:

mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 5000  |
+-----------------+-------+
1 row in set (0.00 sec)

To OP

timeout related

I had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.

I suggest that you increase this value to 100k or disable connection pooling Pooling=false

UPDATED

he has two questions.

Q1 - what happens if I disable pooling Slow down making DB connection. connection pooling is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool

Q2 - Can the value of pooling be increased or the maximum is 100?

you can increase but I'm sure what is MAX value, maybe max_connections in my.cnf

My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.

If you have Stress Test tool like JMeter you can test youself.

You can also use the setProperty method like below

document.getElementById('divName').style.setProperty("top", "100px");

You should definitely extend you ArrayListAdapter and implement this in your getView() method. The second parameter (a View) should be inflated if it's value is null, take advantage of it and set it an onClickListener() just after inflating.

Suposing it's called your second getView()'s parameter is called convertView:

convertView.setOnClickListener(new View.OnClickListener() {
  public void onClick(final View v) {
    if (isSamsung) {
      final Intent intent = new Intent(this, SamsungInfo.class);
      startActivity(intent);
    }
    else if (...) {
      ...
    }
  }
}

If you want some info on how to extend ArrayListAdapter, I recommend this link.

Hi I am also facing this issue and I solve this using below example code

For j = 1 To MyTemplte.Sheets.Count

       If MyTemplte.Sheets(j).Visible = 0 Then
           GoTo DoNothing        
       End If 


'process for this for loop
DoNothing:

Next j 

I used the method below which really is a conundrum of all the ones above. I also found that onOptionsItemSelected is never activated.

    mDrawerToggle.setDrawerIndicatorEnabled(false);
    getSupportActionBar().setHomeButtonEnabled(true);

    Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
    if (toolbar != null) {
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
    }

This should do it:

[^a-zA-Z0-9]

Basically it matches all non-alphanumeric characters.

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

body {_x000D_
  height: 2000px;_x000D_
  padding-top: 100px;_x000D_
}_x000D_
code {_x000D_
  padding: 5px;_x000D_
  background: #efefef;_x000D_
}_x000D_
#target {_x000D_
  color: #c00;_x000D_
  font: 15px arial;_x000D_
  padding: 10px;_x000D_
  margin: 10px;_x000D_
  border: 1px solid #c00;_x000D_
  width: 200px;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="target">This <code>div</code> is going to be fixed</div>

Using the [key] didn't work for me but using an id property does it. I just add this property in my class.

public int id {get; set;}

If you want to get the first element whose id is 1 while object is being searched, you can use this function:

function customFilter(object){
    if(object.hasOwnProperty('id') && object["id"] == 1)
        return object;

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            var o = customFilter(object[Object.keys(object)[i]]);
            if(o != null)
                return o;
        }
    }

    return null;
}

If you want to get all elements whose id is 1, then (all elements whose id is 1 are stored in result as you see):

function customFilter(object, result){
    if(object.hasOwnProperty('id') && object.id == 1)
        result.push(object);

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            customFilter(object[Object.keys(object)[i]], result);
        }
    }
}

Eclipse has got the concept of incremental builds.This is incredibly useful as it saves a lot of time.

How is this Useful

Say you just changed a single .java file. The incremental builders will be able to compile the code without having to recompile everything(which will take more time).

Now what's the problem with Maven Plugins

Most of the maven plugins aren't designed for incremental builds and hence it creates trouble for m2e. m2e doesn't know if the plugin goal is something which is crucial or if it is irrelevant. If it just executes every plugin when a single file changes, it's gonna take lots of time.

This is the reason why m2e relies on metadata information to figure out how the execution should be handled. m2e has come up with different options to provide this metadata information and the order of preference is as below(highest to lowest)

1. pom.xml file of the project
2. parent, grand-parent and so on pom.xml files
3. [m2e 1.2+] workspace preferences
4. installed m2e extensions
5. [m2e 1.1+] lifecycle mapping metadata provided by maven plugin
6. default lifecycle mapping metadata shipped with m2e

1,2 refers to specifying pluginManagement section in the tag of your pom file or any of it's parents. M2E reads this configuration to configure the project.Below snippet instructs m2e to ignore the jslint and compress goals of the yuicompressor-maven-plugin

<pluginManagement>
        <plugins>
            <!--This plugin's configuration is used to store Eclipse m2e settings 
                only. It has no influence on the Maven build itself. -->
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>net.alchim31.maven</groupId>
                                    <artifactId>yuicompressor-maven-plugin</artifactId>
                                    <versionRange>[1.0,)</versionRange>
                                    <goals>
                                        <goal>compress</goal>
                                        <goal>jslint</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <ignore />
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

3) In case you don't prefer polluting your pom file with this metadata, you can store this in an external XML file(option 3). Below is a sample mapping file which instructs m2e to ignore the jslint and compress goals of the yuicompressor-maven-plugin

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
    <pluginExecutions>
        <pluginExecution>
            <pluginExecutionFilter>
                <groupId>net.alchim31.maven</groupId>
                <artifactId>yuicompressor-maven-plugin</artifactId>
                <versionRange>[1.0,)</versionRange>
                <goals>
                    <goal>compress</goal>
                    <goal>jslint</goal>
                </goals>
            </pluginExecutionFilter>
            <action>
                <ignore/>
            </action>
        </pluginExecution>
    </pluginExecutions>
</lifecycleMappingMetadata>

4) In case you don't like any of these 3 options, you can use an m2e connector(extension) for the maven plugin.The connector will in turn provide the metadata to m2e. You can see an example of the metadata information within a connector at this link . You might have noticed that the metadata refers to a configurator. This simply means that m2e will delegate the responsibility to that particular java class supplied by the extension author.The configurator can configure the project(like say add additional source folders etc) and decide whether to execute the actual maven plugin during an incremental build(if not properly managed within the configurator, it can lead to endless project builds)

Refer these links for an example of the configuratior(link1,link2). So in case the plugin is something which can be managed via an external connector then you can install it. m2e maintains a list of such connectors contributed by other developers.This is known as the discovery catalog. m2e will prompt you to install a connector if you don't already have any lifecycle mapping metadata for the execution through any of the options(1-6) and the discovery catalog has got some extension which can manage the execution.

The below image shows how m2e prompts you to install the connector for the build-helper-maven-plugin. .

5)m2e encourages the plugin authors to support incremental build and supply lifecycle mapping within the maven-plugin itself.This would mean that users won't have to use any additional lifecycle mappings or connectors.Some plugin authors have already implemented this

6) By default m2e holds the lifecycle mapping metadata for most of the commonly used plugins like the maven-compiler-plugin and many others.

Now back to the question :You can probably just provide an ignore life cycle mapping in 1, 2 or 3 for that specific goal which is creating trouble for you.

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

After some tinkering I came up with this:

template<int n>
class Printer
{
public:
    Printer()
    {        
        std::cout << (n + 1) << std::endl;
        mNextPrinter.reset(new NextPrinter);
    }

private:
    typedef Printer<n + 1> NextPrinter;
    std::auto_ptr<NextPrinter> mNextPrinter;
};

template<>
class Printer<1000>
{
};

int main()
{
    Printer<0> p;
    return 0;
}

Later @ybungalobill's submission inspired me to this much simpler version:

struct NumberPrinter
{
    NumberPrinter()
    {
        static int fNumber = 1;
        std::cout << fNumber++ << std::endl;
    }
};


int main()
{
    NumberPrinter n[1000];
    return 0;
}

You're looking for tooltip

For the basic tooltip, you want:

<div title="This is my tooltip">

For a fancier javascript version, you can look into:

http://www.designer-daily.com/jquery-prototype-mootool-tooltips-12632

The above link gives you 12 options for tooltips.

I suggest removing the below code from getMails

 .catch(error => { throw error})

In your main function you should put await and related code in Try block and also add one catch block where you failure code.

you function gmaiLHelper.getEmails should return a promise which has reject and resolve in it.

Now while calling and using await put that in try catch block(remove the .catch) as below.

router.get("/emailfetch", authCheck, async (req, res) => {
  //listing messages in users mailbox 
try{
  let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
}
catch (error) { 
 // your catch block code goes here
})

Note that if you've got your filesystem mounted with noatime for performance reasons, then the atime will likely show the creation time. Given that noatime results in a massive performance boost (by removing a disk write for every time a file is read), it may be a sensible configuration option that also gives you the results you want.

i had same problem. i updated to new version of VirtualBox 5.2.26 and checked to make sure Bridge Adapter was enabled in the installation process now is working

This can be done in two steps:

• For each source directory you should create own module.
• In all modules you should specify the same build directory: ${build.directory}

If you work with started Jetty (jetty:run), then recompilation of any class in any module (with Maven, IDEA or Eclipse) will lead to Jetty's restart. The same behavior you'll get for modified resources.

Correction:

Check your script include tag, is it using

type="application/javascript" src="/path/to/jquery" 

change to

type="text/javascript" src="/path/to/jquery" 

Assuming you don't store things like the '+', '()', '-', spaces and what-have-yous (and why would you, they are presentational concerns which would vary based on local customs and the network distributions anyways), the ITU-T recommendation E.164 for the international telephone network (which most national networks are connected via) specifies that the entire number (including country code, but not including prefixes such as the international calling prefix necessary for dialling out, which varies from country to country, nor including suffixes, such as PBX extension numbers) be at most 15 characters.

Call prefixes depend on the caller, not the callee, and thus shouldn't (in many circumstances) be stored with a phone number. If the database stores data for a personal address book (in which case storing the international call prefix makes sense), the longest international prefixes you'd have to deal with (according to Wikipedia) are currently 5 digits, in Finland.

As for suffixes, some PBXs support up to 11 digit extensions (again, according to Wikipedia). Since PBX extension numbers are part of a different dialing plan (PBXs are separate from phone companies' exchanges), extension numbers need to be distinguishable from phone numbers, either with a separator character or by storing them in a different column.

You can use timespan

TimeSpan timeSpan = new TimeSpan(2, 14, 18);
Console.WriteLine(timeSpan.ToString());     // Displays "02:14:18".

[Edit]
Considering the other answers and the edit to the question, I would still use TimeSpan. No point in creating a new structure where an existing one from the framework suffice.
On these lines you would end up duplicating many native data types.

Change position:absolute; to position:fixed;

In my case

[assembly: System.Resources.NeutralResourcesLanguage("ru-RU")]

in the AssemblyInfo.cs prevented things to work as usual.

open http://localhost:8080/ in browser, if you get tomcat home page. it means tomcat is running

No, you will have to use OR to combine your LIKE statements:

SELECT 
   * 
FROM 
   table
WHERE 
   column LIKE 'Text%' OR 
   column LIKE 'Link%' OR 
   column LIKE 'Hello%' OR
   column LIKE '%World%'

Have you looked at Full-Text Search?

You can also overload the Function prototype:

// partially applies the specified arguments to a function, returning a new function
Function.prototype.curry = function( ) {
    var func = this;
    var slice = Array.prototype.slice;
    var appliedArgs = slice.call( arguments, 0 );

    return function( ) {
        var leftoverArgs = slice.call( arguments, 0 );
        return func.apply( this, appliedArgs.concat( leftoverArgs ) );
    };
};

// can do other fancy things:

// flips the first two arguments of a function
Function.prototype.flip = function( ) {
    var func = this;
    return function( ) {
        var first = arguments[0];
        var second = arguments[1];
        var rest = Array.prototype.slice.call( arguments, 2 );
        var newArgs = [second, first].concat( rest );

        return func.apply( this, newArgs );
    };
};

/*
e.g.

var foo = function( a, b, c, d ) { console.log( a, b, c, d ); }
var iAmA = foo.curry( "I", "am", "a" );

For run all lines of GridView don't use for loop, use foreach loop like:

foreach (GridViewRow row in yourGridName.Rows) //Running all lines of grid
{
    if (row.RowType == DataControlRowType.DataRow)
    {
         CheckBox chkRow = (row.Cells[0].FindControl("chkRow") as CheckBox);

         if (chkRow.Checked)
         {
              //if checked do something
         }
    }
}

It is highly unlikely that adding NameVirtualHost *:443 is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).

If you're running a relatively stock Apache configuration, you probably have this somewhere:

<VirtualHost _default_:443>

Your best bet is to either:

• Place your additional SSL configuration into this existing VirtualHost container, or
• Comment out this entire VirtualHost block and create a new one. Don't forget to include all the relevant SSL options.

Try:
$data = file_get_contents ("file.json");
        $json = json_decode($data, true);
        foreach ($json as $key => $value) {
            if (!is_array($value)) {
                echo $key . '=>' . $value . '<br/>';
            } else {
                foreach ($value as $key => $val) {
                    echo $key . '=>' . $val . '<br/>';
                }
            }
        }

First, have to check

SELECT * FROM university WHERE course_name LIKE '%&amp%'

Next, have to update

UPDATE university SET course_name = REPLACE(course_name, '&amp', '&') WHERE id = 1

Results: Engineering &amp Technology => Engineering & Technology

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

Assuming your server side script doesn't set the proper Content-Type: application/json response header you will need to indicate to jQuery that this is JSON by using the dataType: 'json' parameter.

Then you could use the $.each() function to loop through the data:

$.ajax({ 
    type: 'GET', 
    url: 'http://example/functions.php', 
    data: { get_param: 'value' }, 
    dataType: 'json',
    success: function (data) { 
        $.each(data, function(index, element) {
            $('body').append($('<div>', {
                text: element.name
            }));
        });
    }
});

or use the $.getJSON method:

$.getJSON('/functions.php', { get_param: 'value' }, function(data) {
    $.each(data, function(index, element) {
        $('body').append($('<div>', {
            text: element.name
        }));
    });
});

Misconceptions

There are few common misconceptions regarding WebSocket and Socket.IO:

1. The first misconception is that using Socket.IO is significantly easier than using WebSocket which doesn't seem to be the case. See examples below.

2. The second misconception is that WebSocket is not widely supported in the browsers. See below for more info.

3. The third misconception is that Socket.IO downgrades the connection as a fallback on older browsers. It actually assumes that the browser is old and starts an AJAX connection to the server, that gets later upgraded on browsers supporting WebSocket, after some traffic is exchanged. See below for details.

My experiment

I wrote an npm module to demonstrate the difference between WebSocket and Socket.IO:

• https://www.npmjs.com/package/websocket-vs-socket.io
• https://github.com/rsp/node-websocket-vs-socket.io

It is a simple example of server-side and client-side code - the client connects to the server using either WebSocket or Socket.IO and the server sends three messages in 1s intervals, which are added to the DOM by the client.

Server-side

Compare the server-side example of using WebSocket and Socket.IO to do the same in an Express.js app:

WebSocket Server

WebSocket server example using Express.js:

var path = require('path');
var app = require('express')();
var ws = require('express-ws')(app);
app.get('/', (req, res) => {
  console.error('express connection');
  res.sendFile(path.join(__dirname, 'ws.html'));
});
app.ws('/', (s, req) => {
  console.error('websocket connection');
  for (var t = 0; t < 3; t++)
    setTimeout(() => s.send('message from server', ()=>{}), 1000*t);
});
app.listen(3001, () => console.error('listening on http://localhost:3001/'));
console.error('websocket example');

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/ws.js

Socket.IO Server

Socket.IO server example using Express.js:

var path = require('path');
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', (req, res) => {
  console.error('express connection');
  res.sendFile(path.join(__dirname, 'si.html'));
});
io.on('connection', s => {
  console.error('socket.io connection');
  for (var t = 0; t < 3; t++)
    setTimeout(() => s.emit('message', 'message from server'), 1000*t);
});
http.listen(3002, () => console.error('listening on http://localhost:3002/'));
console.error('socket.io example');

Client-side

Compare the client-side example of using WebSocket and Socket.IO to do the same in the browser:

WebSocket Client

WebSocket client example using vanilla JavaScript:

var l = document.getElementById('l');
var log = function (m) {
    var i = document.createElement('li');
    i.innerText = new Date().toISOString()+' '+m;
    l.appendChild(i);
}
log('opening websocket connection');
var s = new WebSocket('ws://'+window.location.host+'/');
s.addEventListener('error', function (m) { log("error"); });
s.addEventListener('open', function (m) { log("websocket connection open"); });
s.addEventListener('message', function (m) { log(m.data); });

Source: https://github.com/rsp/node-websocket-vs-socket.io/blob/master/ws.html

Socket.IO Client

Socket.IO client example using vanilla JavaScript:

var l = document.getElementById('l');
var log = function (m) {
    var i = document.createElement('li');
    i.innerText = new Date().toISOString()+' '+m;
    l.appendChild(i);
}
log('opening socket.io connection');
var s = io();
s.on('connect_error', function (m) { log("error"); });
s.on('connect', function (m) { log("socket.io connection open"); });
s.on('message', function (m) { log(m); });

Network traffic

To see the difference in network traffic you can run my test. Here are the results that I got:

WebSocket Results

2 requests, 1.50 KB, 0.05 s

From those 2 requests:

1. HTML page itself
2. connection upgrade to WebSocket

(The connection upgrade request is visible on the developer tools with a 101 Switching Protocols response.)

Socket.IO Results

6 requests, 181.56 KB, 0.25 s

From those 6 requests:

1. the HTML page itself
2. Socket.IO's JavaScript (180 kilobytes)
3. first long polling AJAX request
4. second long polling AJAX request
5. third long polling AJAX request
6. connection upgrade to WebSocket

Test yourself

Quick start:

# Install:
npm i -g websocket-vs-socket.io
# Run the server:
websocket-vs-socket.io

Open http://localhost:3001/ in your browser, open developer tools with Shift+Ctrl+I, open the Network tab and reload the page with Ctrl+R to see the network traffic for the WebSocket version.

Open http://localhost:3002/ in your browser, open developer tools with Shift+Ctrl+I, open the Network tab and reload the page with Ctrl+R to see the network traffic for the Socket.IO version.

To uninstall:

# Uninstall:
npm rm -g websocket-vs-socket.io

Browser compatibility

As of June 2016 WebSocket works on everything except Opera Mini, including IE higher than 9.

This is the browser compatibility of WebSocket on Can I Use as of June 2016:

I was going to leave this after this comment: Should I check in folder "node_modules" to Git when creating a Node.js app on Heroku?

But Stack Overflow was formatting it weirdly.

If you don't have identical machines and are checking in node_modules, do a .gitignore on the native extensions. Our .gitignore looks like:

# Ignore native extensions in the node_modules folder (things changed by npm rebuild)
node_modules/**/*.node
node_modules/**/*.o
node_modules/**/*.a
node_modules/**/*.mk
node_modules/**/*.gypi
node_modules/**/*.target
node_modules/**/.deps/
node_modules/**/build/Makefile
node_modules/**/**/build/Makefile

Test this by first checking everything in, and then have another developer do the following:

rm -rf node_modules
git checkout -- node_modules
npm rebuild
git status

Ensure that no files changed.

For people who have come here to look for a general answer for duplicate row removal, use !duplicated():

a <- c(rep("A", 3), rep("B", 3), rep("C",2))
b <- c(1,1,2,4,1,1,2,2)
df <-data.frame(a,b)

duplicated(df)
[1] FALSE  TRUE FALSE FALSE FALSE  TRUE FALSE  TRUE

> df[duplicated(df), ]
  a b
2 A 1
6 B 1
8 C 2

> df[!duplicated(df), ]
  a b
1 A 1
3 A 2
4 B 4
5 B 1
7 C 2

Answer from: Removing duplicated rows from R data frame

For those who don't care about IE6/IE7, the same guy who wrote Raphael built an svg engine specifically for modern browsers: Snap.svg .. they have a really nice site with good docs: http://snapsvg.io

snap.svg couldn't be easier to use right out of the box and can manipulate/update existing SVGs or generate new ones. You can read this stuff on the snap.io about page but here's a quick run down:

Cons

• To make use of snap's features you must forgo on support for older browsers. Raphael supports browsers like IE6/IE7, snap features are only supported by IE9 and up, Safari, Chrome, Firefox, and Opera.

Pros

• Implements the full features of SVG like masking, clipping, patterns, full gradients, groups, and more.

• Ability to work with existing SVGs: content does not have to be generated with Snap for it to work with Snap, allowing you to create the content with any common design tools.

• Full animation support using a straightforward, easy-to-implement JavaScript API

• Works with strings of SVGs (for example, SVG files loaded via Ajax) without having to actually render them first, similar to a resource container or sprite sheet.

I had the same problem and fix it using following python script. hope it help others.

it is because of using tabs and spaces for indenting code. in this script I replace each tab with four spaces.

input_file = "source code path here"  # e.g. source.py
output_file = "out put file path here"  # e.g out.py
with open(input_file, 'r') as source:
    with open(output_file, 'a+') as result:
        for line in source:
            line = line.replace('\t', '    ')
            result.write(line)

if you use sublime or any other editor which gives you the tool to replace text you can replace all tabs by four spaces from editor.

Here is a python based solution that uses recursion as well as memoization resulting in a complexity of O(mxn)

    def get_combinations_dynamic(self, amount, coins, memo):
    end_index = len(coins) - 1
    memo_key = str(amount)+'->'+str(coins)
    if memo_key in memo:
        return memo[memo_key]
    remaining_amount = amount
    if amount < 0:
        return []
    if amount == 0:
        return [[]]
    combinations = []
    if len(coins) <= 1:
        if amount % coins[0] == 0:
            combination = []
            for i in range(amount // coins[0]):
                combination.append(coins[0])
            list.sort(combination)
            if combination not in combinations:
                combinations.append(combination)
    else:
        k = 0
        while remaining_amount >= 0:
            sub_combinations = self.get_combinations_dynamic(remaining_amount, coins[:end_index], memo)
            for combination in sub_combinations:
                temp = combination[:]
                for i in range(k):
                    temp.append(coins[end_index])
                list.sort(temp)
                if temp not in combinations:
                    combinations.append(temp)
            k += 1
            remaining_amount -= coins[end_index]
    memo[memo_key] = combinations
    return combinations

In addition to Richard Simões answer you can also use the Page Visibility API.

if (!document.hidden) {
    // do what you need
}

This specification defines a means for site developers to programmatically determine the current visibility state of the page in order to develop power and CPU efficient web applications.

Learn more (2019 update)

• All modern browsers are supporting document.hidden
• http://davidwalsh.name/page-visibility
• https://developers.google.com/chrome/whitepapers/pagevisibility
• Example pausing a video when window/tab is hidden
  https://web.archive.org/web/20170609212707/http://www.samdutton.com/pageVisibility/

To iterate through all elements

XDocument xdoc = XDocument.Load("input.xml");
foreach (XElement element in xdoc.Descendants())
{
    Console.WriteLine(element.Name);
}

It may be helpful to make an alias for it.

Install and find your tensorboard location:

pip install tensorboard
pip show tensorboard

Add the following alias in .bashrc:

alias tensorboard='python pathShownByPip/tensorboard/main.py'

Open another terminal or run exec bash.

For Windows users, cd into pathShownByPip\tensorboard and run python main.py from there.

For Python 3.x, use pip3 instead of pip, and don't forget to use python3 in the alias.

getResourceAsStream() look inside of your resource folder. So the fil shold be placed inside of the defined resource-folder i.e if the file reside in /src/main/resources/properties --> then the path should be /properties/yourFilename.

getClass.getResourceAsStream(/properties/yourFilename)

On a Spanish keyboard it is CTRL + ¿ (or CTRL + ¡).

Try this

If you by writing "non letters and numbers" exclude more than [A-Za-z0-9] (ie. considering letters like åäö to be letters to) and want to be able to accurately handle UTF-8 strings \p{L} and \p{N} will be of aid.

1. \p{N} will match any "Number"
2. \p{L} will match any "Letter Character", which includes
   • Lower case letter
   • Modifier letter
   • Other letter
   • Title case letter
   • Upper case letter

$data = "Thäre!wouldn't%bé#äny";

$new_data = str_replace  ("'", "", $data);
$new_data = preg_replace ('/[^\p{L}\p{N}]/u', '_', $new_data);

var_dump (
  $new_data
);

output

string(23) "Thäre_wouldnt_bé_äny"

I don't see any problem, unless you are not managing them using a connection pool.

If you use connection pool, these connections are re-used instead of initiating new connections. so basically, leaving open connections and re-use them it is less problematic than re-creating them each time.

You could also use in_array as follows:

<?php
$found = null;
$people = array(3,20,2);
$criminals = array( 2, 4, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20);
foreach($people as $num) {
    if (in_array($num,$criminals)) {
        $found[$num] = true;
    } 
}
var_dump($found);
// array(2) { [20]=> bool(true)   [2]=> bool(true) }

While array_intersect is certainly more convenient to use, it turns out that its not really superior in terms of performance. I created this script too:

<?php
$found = null;
$people = array(3,20,2);
$criminals = array( 2, 4, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20);
$fastfind = array_intersect($people,$criminals);
var_dump($fastfind);
// array(2) { [1]=> int(20)   [2]=> int(2) }

Then, I ran both snippets respectively at: http://3v4l.org/WGhO7/perf#tabs and http://3v4l.org/g1Hnu/perf#tabs and checked the performance of each. The interesting thing is that the total CPU time, i.e. user time + system time is the same for PHP5.6 and the memory also is the same. The total CPU time under PHP5.4 is less for in_array than array_intersect, albeit marginally so.

When using the data on the server, your characters can reach with the addition of slashes eg if string = {"hello"} comes as string = {\ "hello \"} to solve the following function can be used later to use json decode.

<?php
function stripslashes_deep($value)
{
    $value = is_array($value) ?
                array_map('stripslashes_deep', $value) :
                stripslashes($value);

    return $value;
}

$array = $_POST['jObject'];
$array = stripslashes_deep($array);

$data = json_decode($array, true);
print_r($data);
?>

Almost all Magento Models have a corresponding Collection object that can be used to fetch multiple instances of a Model.

To instantiate a Product collection, do the following

$collection = Mage::getModel('catalog/product')->getCollection();

Products are a Magento EAV style Model, so you'll need to add on any additional attributes that you want to return.

$collection = Mage::getModel('catalog/product')->getCollection();

//fetch name and orig_price into data
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

There's multiple syntaxes for setting filters on collections. I always use the verbose one below, but you might want to inspect the Magento source for additional ways the filtering methods can be used.

The following shows how to filter by a range of values (greater than AND less than)

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products whose orig_price is greater than (gt) 100
$collection->addFieldToFilter(array(
    array('attribute'=>'orig_price','gt'=>'100'),
)); 

//AND filter for products whose orig_price is less than (lt) 130
$collection->addFieldToFilter(array(
    array('attribute'=>'orig_price','lt'=>'130'),
));

While this will filter by a name that equals one thing OR another.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
    array('attribute'=>'name','eq'=>'Widget A'),
    array('attribute'=>'name','eq'=>'Widget B'),        
));

A full list of the supported short conditionals (eq,lt, etc.) can be found in the _getConditionSql method in lib/Varien/Data/Collection/Db.php

Finally, all Magento collections may be iterated over (the base collection class implements on of the the iterator interfaces). This is how you'll grab your products once filters are set.

$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToSelect('name');  
$collection->addAttributeToSelect('orig_price');    

//filter for products who name is equal (eq) to Widget A, or equal (eq) to Widget B
$collection->addFieldToFilter(array(
    array('attribute'=>'name','eq'=>'Widget A'),
    array('attribute'=>'name','eq'=>'Widget B'),        
));

foreach ($collection as $product) {
    //var_dump($product);
    var_dump($product->getData());
}

Here is my 2 cents:

double dX = x1 - x2;
double dY = y1 - y2;
double multi = dX * dX + dY * dY;
double rad = Math.Round(Math.Sqrt(multi), 3, MidpointRounding.AwayFromZero);

x1, y1 is the first coordinate and x2, y2 the second. The last line is the square root with it rounded to 3 decimal places.

The documentation on CREATE EVENT is quite good, but it takes a while to get it right.

You have two problems, first, making the event recur, second, making it run at 13:00 daily.

This example creates a recurring event.

CREATE EVENT e_hourly
    ON SCHEDULE
      EVERY 1 HOUR
    COMMENT 'Clears out sessions table each hour.'
    DO
      DELETE FROM site_activity.sessions;

When in the command-line MySQL client, you can:

SHOW EVENTS;

This lists each event with its metadata, like if it should run once only, or be recurring.

The second problem: pointing the recurring event to a specific schedule item.

By trying out different kinds of expression, we can come up with something like:

CREATE EVENT IF NOT EXISTS `session_cleaner_event`
ON SCHEDULE
  EVERY 13 DAY_HOUR
  COMMENT 'Clean up sessions at 13:00 daily!'
  DO
    DELETE FROM site_activity.sessions;

You can do it using type:

type"C:\<Directory containing files>\*.txt"> merged.txt

all the files in the directory will be appendeded to the file merged.txt.

$ pip3 install pypiwin32

Sometimes using pip3 also works if just pip by itself is not working.

I'd like to report a bug regarding the section Source of data to search in the first answer when using en dash (–) or em dash (—) within the filename.

More specifically, if you are about to use the first option - filenames specified as arguments, the file won't be found. As soon as you use either option 2 - stdin via redirection or 3 - data stream from a pipe, findstr will find the file.

For example, this simple batch script:

echo off
chcp 1250 > nul
set INTEXTFILE1=filename with – dash.txt
set INTEXTFILE2=filename with — dash.txt

rem 3 way of findstr use with en dashed filename
echo.
echo Filename with en dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE1%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE1%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE1%" | findstr .
echo.
echo.
rem The same set of operations with em dashed filename
echo Filename with em dash:
echo.
echo 1. As argument
findstr . "%INTEXTFILE2%"
echo.
echo 2. As stdin via redirection
findstr . < "%INTEXTFILE2%"
echo.
echo 3. As datastream from a pipe
type "%INTEXTFILE2%" | findstr .
echo.

pause

will print:

Filename with en dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an en dash.

3. As datastream from a pipe
   I am the file with an en dash.

Filename with em dash:

1. As argument
   FINDSTR: Cannot open filename with - dash.txt

2. As stdin via redirection
   I am the file with an em dash.

3. As datastream from a pipe
   I am the file with an em dash.

Hope it helps.

Since JSF 2.3 all the bean scopes defined in package javax.faces.bean package have been deprecated to align the scopes with CDI. Moreover they're only applicable if your bean is using @ManagedBean annotation. If you are using JSF versions below 2.3 refer to the legacy answer at the end.

From JSF 2.3 here are scopes that can be used on JSF Backing Beans:

1. @javax.enterprise.context.ApplicationScoped: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. This is useful when you have data for whole application.

2. @javax.enterprise.context.SessionScoped: The session scope persists from the time that a session is established until session termination. The session context is shared between all requests that occur in the same HTTP session. This is useful when you wont to save data for a specific client for a particular session.

3. @javax.enterprise.context.ConversationScoped: The conversation scope persists as log as the bean lives. The scope provides 2 methods: Conversation.begin() and Conversation.end(). These methods should called explicitly, either to start or end the life of a bean.

4. @javax.enterprise.context.RequestScoped: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

5. @javax.faces.flow.FlowScoped: The Flow scope persists as long as the Flow lives. A flow may be defined as a contained set of pages (or views) that define a unit of work. Flow scoped been is active as long as user navigates with in the Flow.

6. @javax.faces.view.ViewScoped: A bean in view scope persists while the same JSF page is redisplayed. As soon as the user navigates to a different page, the bean goes out of scope.

The following legacy answer applies JSF version before 2.3

As of JSF 2.x there are 4 Bean Scopes:

• @SessionScoped
• @RequestScoped
• @ApplicationScoped
• @ViewScoped

Session Scope: The session scope persists from the time that a session is established until session termination. A session terminates if the web application invokes the invalidate method on the HttpSession object, or if it times out.

RequestScope: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

ApplicationScope: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. You place managed beans into the application scope if a single bean should be shared among all instances of a web application. The bean is constructed when it is first requested by any user of the application, and it stays alive until the web application is removed from the application server.

ViewScope: View scope was added in JSF 2.0. A bean in view scope persists while the same JSF page is redisplayed. (The JSF specification uses the term view for a JSF page.) As soon as the user navigates to a different page, the bean goes out of scope.

Choose the scope you based on your requirement.

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

Suppose we have a collection like below:

{ 
  "_id":"1234"
  "open":"Yes"
  "things":{
             "paper":1234
             "bottle":"Available"
             "bottle_count":40
            } 
}

We want to know if the bottle field is present or not?

Ans:

db.products.find({"things.bottle":{"$exists":true}})

Even after applying above defined project specific settings on IntelliJ as well as Eclipse, it was still failing for me !

what worked for me was addition of maven plugin with source and target with 1.8 setting in POM XML:

In the latest version of the SDK, you would use the setBackgroundResource method.

public void onClick(View v) {
   if(v == ButtonName) {
     ButtonName.setBackgroundResource(R.drawable.ImageResource);
   }
}

Do You need exact number of lines or only its approximation? I happen to process large files in parallel and often I don't need to know exact count of lines - I then revert to sampling. Split the file into ten 1MB chunks and count lines in each chunk, then multiply it by 10 and You'll receive pretty good approximation of line count.

If you still have problems and are using nvm make sure to set the nvm node environment.

To select the latest version installed. To see versions use nvm list.

nvm use node
sudo npm remove -g @angular/cli
sudo npm install -g @angular/cli

Or to install a specific version use:

sudo npm install -g @angular/[email protected]

If you dir permission errors use:

sudo npm install -g @angular/[email protected] --unsafe-perm

All the code is client side, I hope you fine this helpful:

First thing there are 3 functions we will use:

    function setCookie(c_name, value, exdays) {
            var exdate = new Date();
            exdate.setDate(exdate.getDate() + exdays);
            var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
            document.cookie = c_name + "=" + c_value;
        }

    function getCookie(c_name) {
        var i, x, y, ARRcookies = document.cookie.split(";");
        for (i = 0; i < ARRcookies.length; i++) {
            x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
            y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
            x = x.replace(/^\s+|\s+$/g, "");
            if (x == c_name) {
                return unescape(y);
            }
        }
    }

    function DeleteCookie(name) {
            document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
        }

Now we will start with the page load:

$(window).load(function () {
 //if IsRefresh cookie exists
 var IsRefresh = getCookie("IsRefresh");
 if (IsRefresh != null && IsRefresh != "") {
    //cookie exists then you refreshed this page(F5, reload button or right click and reload)
    //SOME CODE
    DeleteCookie("IsRefresh");
 }
 else {
    //cookie doesnt exists then you landed on this page
    //SOME CODE
    setCookie("IsRefresh", "true", 1);
 }
})

Here is a more generalized Swift extension to create border for any UIView subclass:

import UIKit

extension UIView {      
  func addTopBorderWithColor(color: UIColor, width: CGFloat) {
    let border = CALayer()
    border.backgroundColor = color.CGColor
    border.frame = CGRectMake(0, 0, self.frame.size.width, width)
    self.layer.addSublayer(border)
  }

  func addRightBorderWithColor(color: UIColor, width: CGFloat) {
    let border = CALayer()
    border.backgroundColor = color.CGColor
    border.frame = CGRectMake(self.frame.size.width - width, 0, width, self.frame.size.height)
    self.layer.addSublayer(border)
  }

  func addBottomBorderWithColor(color: UIColor, width: CGFloat) {
    let border = CALayer()
    border.backgroundColor = color.CGColor
    border.frame = CGRectMake(0, self.frame.size.height - width, self.frame.size.width, width)
    self.layer.addSublayer(border)
  }

  func addLeftBorderWithColor(color: UIColor, width: CGFloat) {
    let border = CALayer()
    border.backgroundColor = color.CGColor
    border.frame = CGRectMake(0, 0, width, self.frame.size.height)
    self.layer.addSublayer(border)
  }
}

Swift 3

extension UIView {
    func addTopBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: 0, width: self.frame.size.width, height: width)
        self.layer.addSublayer(border)
    }

    func addRightBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: self.frame.size.width - width, y: 0, width: width, height: self.frame.size.height)
        self.layer.addSublayer(border)
    }

    func addBottomBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height: width)
        self.layer.addSublayer(border)
    }

    func addLeftBorderWithColor(color: UIColor, width: CGFloat) {
        let border = CALayer()
        border.backgroundColor = color.cgColor
        border.frame = CGRect(x: 0, y: 0, width: width, height: self.frame.size.height)
        self.layer.addSublayer(border)
    }
}

OS : Windows 7 & IIS 7

If you still have permission denied after adding IUSR & NETWORK SERVICE. Add also IIS_WPG. The addition of this last user solved my problem.

For people who can't find those users: when you're trying to add a user in security of the folder (properties of the folder), click on "Advanced" of the window "Select Users or Groups". Change the location to the computer name then click on "Find Now". You'll find those users in the list below.

Current date is in yyyy-mm-dd format. You can convert it into yyyymmdd format using substring function:

select substr(current date,1,4)||substr(current date,6,2)||substr(currentdate,9,2)

Actually, the correct solution is:

composer require vendor/package

Taken from the CLI documentation for Composer:

The require command adds new packages to the composer.json file from the current directory.

php composer.phar require

After adding/changing the requirements, the modified requirements will be installed or updated.

If you do not want to choose requirements interactively, you can just pass them to the command.

php composer.phar require vendor/package:2.* vendor/package2:dev-master

While it is true that composer update installs new packages found in composer.json, it will also update the composer.lock file and any installed packages according to any fuzzy logic (> or * chars after the colons) found in composer.json! This can be avoided by using composer update vendor/package, but I wouldn't recommend making a habit of it, as you're one forgotten argument away from a potentially broken project…

Keep things sane and stick with composer require vendor/package for adding new dependencies!

The above claim that "If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing" seems to be quite wrong - at least with Chrome 31.0.1650.57 m or depending on your definition of "lot of pixel". I would have preferred to comment directly to the respective post - but unfortunately I don't have enough stackoverflow points yet:

I think that I am drawing "a lot of pixels" and therefore I first followed the respective advice for good measure I later changed my implementation to a simple ctx.fillRect(..) for each drawn point, see http://www.wothke.ch/webgl_orbittrap/Orbittrap.htm

Interestingly it turns out the silly ctx.fillRect() implementation in my example is actually at least twice as fast as the ImageData based double buffering approach.

At least for my scenario it seems that the built-in ctx.getImageData/ctx.putImageData is in fact unbelievably SLOW. (It would be interesting to know the percentage of pixels that need to be touched before an ImageData based approach might take the lead..)

Conclusion: If you need to optimize performance you have to profile YOUR code and act on YOUR findings..

Another difference to note is that if you're debugging an application in a Production environment you might not have access to line numbers, so identifying which particular .First() statement in a method threw the exception may be difficult.

The exception message will also not include any Lambda expressions you might have used which would make any problem even are harder to debug.

That's why I always use FirstOrDefault() even though I know a null entry would constitute an exceptional situation.

var customer = context.Customers.FirstOrDefault(i => i.Id == customerId);
if (customer == null)
{
   throw new Exception(string.Format("Can't find customer {0}.", customerId));
}

If you use .netcore 3.1 the simplest way use new configuration system to call CreateDefaultBuilder method of static class Host and configure application

public class Program
{
    public static void Main(string[] args)
    {
        Host.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration((context, config) =>
            {
                IHostEnvironment env = context.HostingEnvironment;
                config.AddEnvironmentVariables()
                    // copy configuration files to output directory
                    .AddJsonFile("appsettings.json")
                    // default prefix for environment variables is DOTNET_
                    .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
                    .AddCommandLine(args);
            })
            .ConfigureServices(services =>
            {
                services.AddSingleton<IHostedService, MySimpleService>();
            })
            .Build()
            .Run();
    }
}

class MySimpleService : IHostedService
{
    public Task StartAsync(CancellationToken cancellationToken)
    {
        Console.WriteLine("StartAsync");
        return Task.CompletedTask;
    }

    public Task StopAsync(CancellationToken cancellationToken)
    {
        Console.WriteLine("StopAsync");
        return Task.CompletedTask;
    }
}

You need set Copy to Output Directory = 'Copy if newer' for the files appsettings.json and appsettings.{environment}.json Also you can set environment variable {prefix}ENVIRONMENT (default prefix is DOTNET) to allow choose specific configuration parameters.

Django employs a slightly modified kind of MVC. There's no concept of a "controller" in Django. The closest proxy is a "view", which tends to cause confusion with MVC converts because in MVC a view is more like Django's "template".

In Django, a "model" is not merely a database abstraction. In some respects, it shares duty with the Django's "view" as the controller of MVC. It holds the entirety of behavior associated with an instance. If that instance needs to interact with an external API as part of it's behavior, then that's still model code. In fact, models aren't required to interact with the database at all, so you could conceivable have models that entirely exist as an interactive layer to an external API. It's a much more free concept of a "model".

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Login();
    } 

    private static bool logOut;

Worked for me.

You need to create an XmlReaderSettings instance and pass that to your XmlReader when you create it. Then you can subscribe to the ValidationEventHandler in the settings to receive validation errors. Your code will end up looking like this:

using System.Xml;
using System.Xml.Schema;
using System.IO;

public class ValidXSD
{
    public static void Main()
    {

        // Set the validation settings.
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);

        // Create the XmlReader object.
        XmlReader reader = XmlReader.Create("inlineSchema.xml", settings);

        // Parse the file. 
        while (reader.Read()) ;

    }
    // Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

One special case for this is if you have used a construction like the following in your ~/.muttrc:

# Reset From email to default
send-hook . "my_hdr From: Real Name <[email protected]>"

This send-hook will override either of these:

mutt -e "set [email protected]"
mutt -e "my_hdr From: Other Name <[email protected]>"

Your emails will still go out with the header:

From: Real Name <[email protected]>

In this case, the only command line solution I've found is actually overriding the send-hook itself:

mutt -e "send-hook . \"my_hdr From: Other Name <[email protected]>\""

You can use the NET START command and then check the ERRORLEVEL environment variable, e.g.

net start [your service]
if %errorlevel% == 2 echo Could not start service.
if %errorlevel% == 0 echo Service started successfully.
echo Errorlevel: %errorlevel%

Disclaimer: I've written this from the top of my head, but I think it'll work.

++x is called preincrement while x++ is called postincrement.

int x = 5, y = 5;

System.out.println(++x); // outputs 6
System.out.println(x); // outputs 6

System.out.println(y++); // outputs 5
System.out.println(y); // outputs 6

create simple method to do that for you:

public void addMulti(String[] strings,List list){
    for (int i = 0; i < strings.length; i++) {
        list.add(strings[i]);
    }
}

Then you can create

String[] wrong ={"1","2","3","4","5","6"};

and add it with this method to your list.

Amiram Korach solution is indeed tidy. Here's an alternative for the sake of versatility.

var count = dtList.Count;
// Perform a reverse tracking.
for (var i = count - 1; i > -1; i--)
{
    if (dtList[i]==string.Empty) dtList.RemoveAt(i);
}
// Keep only the unique list items.
dtList = dtList.Distinct().ToList();

The logcat shows the error, you should call super.onCreate(savedInstanceState) :

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    //... your code
}

Immutable lists are best represented through two-tuples, with None representing NIL. To allow simple formulation of such lists, you can use this function:

def mklist(*args):
    result = None
    for element in reversed(args):
        result = (element, result)
    return result

To work with such lists, I'd rather provide the whole collection of LISP functions (i.e. first, second, nth, etc), than introducing methods.

A solution which worked in my case is:
  1. Go to the module having Main class.
  2. Right click on pom.xml under this module.
  3. Select "Run Maven" -> "UpdateSnapshots"

To rename a solution:

1. In Solution Explorer, right-click the project, select Rename, and enter a new name.

2. In Solution Explorer, right-click the project and select Properties. On the Application tab, change the "Assembly name" and "Default namespace".

3. In the main cs file (or any other code files), rename the namespace declaration to use the new name. For this right-click the namespace and select Refactor > Rename enter a new name. For example: namespace WindowsFormsApplication1

4. Change the AssemblyTitle and AssemblyProduct in Properties/AssemblyInfo.cs.

   [assembly: AssemblyTitle("New Name Here")]
   [assembly: AssemblyDescription("")]
   [assembly: AssemblyConfiguration("")]
   [assembly: AssemblyCompany("")]
   [assembly: AssemblyProduct("New Name Here")]
   [assembly: AssemblyCopyright("Copyright ©  2013")]
   [assembly: AssemblyTrademark("")]
   [assembly: AssemblyCulture("")]
   

5. Delete bin and obj directories physically.

6. Rename the project physical folder directory.

7. Open the SLN file (within notepad or any editor) and change the path to the project.

8. Clean and Rebuild the project.

You can load an assembly using *Assembly.Load** methods. Using Activator.CreateInstance you can create new instances of the type you want. Keep in mind that you have to use the full type name of the class you want to load (for example Namespace.SubNamespace.ClassName). Using the method InvokeMember of the Type class you can invoke methods on the type.

Also, take into account that once loaded, an assembly cannot be unloaded until the whole AppDomain is unloaded too (this is basically a memory leak).

I may be late, but you can try the following code, which worked for me for Drag and Drop.

.dndclass{
    cursor: url('../images/grab1.png'), auto; 

}

.dndclass:active {
    cursor: url('../images/grabbing1.png'), auto;
}

You can use the images below in the URL above. Make sure it is a PNG transparent image. If not, download one from google.

Simple Array

let simpleArray = [1,2,3,4]
let commaSeperated = simpleArray.join(",");
console.log(commaSeperated);

Array of Objects with a particular attributes as comma separated.

let arrayOfObjects = [
{
id : 1,
name : "Name 1",
address : "Address 1"
},
{
id : 2,
name : "Name 2",
address : "Address 2"
},
{
id : 3,
name : "Name 3",
address : "Address 3"
}]
let names = arrayOfObjects.map(x => x.name).join(", ");
console.log(names);

An other approach after trying the solutions below. When you need it clear, just initialise your list to new clear new list.

List<ModelData> dataLists = new ArrayList<>();
                RaporAdapter adapter = new RaporAdapter(AyrintiliRapor.this, dataLists);
                listview.setAdapter(adapter);

Or set visibility to Gone / Invisible up to need

img_pdf.setVisibility(View.INVISIBLE);

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

Using aiopg - The snippet below works perfectly fine

    # items = [10, 11, 12, 13]
    # group = 1
    tup = [(gid, pid) for pid in items]
    args_str = ",".join([str(s) for s in tup])
    # insert into group values (1, 10), (1, 11), (1, 12), (1, 13)
    yield from cur.execute("INSERT INTO group VALUES " + args_str)

Try this

<include
            android:id="@+id/OnlineOffline"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            layout="@layout/YourLayoutName" />

If you want to loop over what you "find", you should use this:

find . -type f -name '*.*' -print0 | while IFS= read -r -d '' file; do
    printf '%s\n' "$file"
done

I've just written a library called jsPDF which generates PDFs using Javascript alone. It's still very young, and I'll be adding features and bug fixes soon. Also got a few ideas for workarounds in browsers that do not support Data URIs. It's licensed under a liberal MIT license.

I came across this question before I started writing it and thought I'd come back and let you know :)

Generate PDFs in Javascript

Example create a "Hello World" PDF file.

// Default export is a4 paper, portrait, using milimeters for units_x000D_
var doc = new jsPDF()_x000D_
_x000D_
doc.text('Hello world!', 10, 10)_x000D_
doc.save('a4.pdf')

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.5/jspdf.debug.js"></script>

For me everything else was almost ok, but somehow my project settings changed & iisExpress was getting used instead of IISLocal. When I changed & pointed to the virtual directory (in IISLocal), it stared working perfectly again.

You can do following

FIDDLE

<div id="circle"></div>

CSS

#circle {
    width: 100px;
    height: 100px;
    background: red;
    -moz-border-radius: 50px;
    -webkit-border-radius: 50px;
    border-radius: 50px;
}

Here are some variations on Sotirios Delimanolis' answer, which was pretty good to begin with (+1). Consider the following:

static <X, Y, Z> Map<X, Z> transform(Map<? extends X, ? extends Y> input,
                                     Function<Y, Z> function) {
    return input.keySet().stream()
        .collect(Collectors.toMap(Function.identity(),
                                  key -> function.apply(input.get(key))));
}

A couple points here. First is the use of wildcards in the generics; this makes the function somewhat more flexible. A wildcard would be necessary if, for example, you wanted the output map to have a key that's a superclass of the input map's key:

Map<String, String> input = new HashMap<String, String>();
input.put("string1", "42");
input.put("string2", "41");
Map<CharSequence, Integer> output = transform(input, Integer::parseInt);

(There is also an example for the map's values, but it's really contrived, and I admit that having the bounded wildcard for Y only helps in edge cases.)

A second point is that instead of running the stream over the input map's entrySet, I ran it over the keySet. This makes the code a little cleaner, I think, at the cost of having to fetch values out of the map instead of from the map entry. Incidentally, I initially had key -> key as the first argument to toMap() and this failed with a type inference error for some reason. Changing it to (X key) -> key worked, as did Function.identity().

Still another variation is as follows:

static <X, Y, Z> Map<X, Z> transform1(Map<? extends X, ? extends Y> input,
                                      Function<Y, Z> function) {
    Map<X, Z> result = new HashMap<>();
    input.forEach((k, v) -> result.put(k, function.apply(v)));
    return result;
}

This uses Map.forEach() instead of streams. This is even simpler, I think, because it dispenses with the collectors, which are somewhat clumsy to use with maps. The reason is that Map.forEach() gives the key and value as separate parameters, whereas the stream has only one value -- and you have to choose whether to use the key or the map entry as that value. On the minus side, this lacks the rich, streamy goodness of the other approaches. :-)

You can run:

valgrind --leak-check=full --log-file="logfile.out" -v [your_program(and its arguments)]

It looks like two of your lines are out of order. You start the process before setting up an event handler to capture the output. It's possible the process is just finishing before the event handler is added.

Switch the lines like so.

p.OutputDataReceived += ...
p.Start();        

I have found this solution for swift2:

var str = "abcdefghi"
let indexForCharacterInString = str.characters.indexOf("c") //returns 2

here's an example for bash:

usage="$(basename "$0") [-h] [-s n] -- program to calculate the answer to life, the universe and everything

where:
    -h  show this help text
    -s  set the seed value (default: 42)"

seed=42
while getopts ':hs:' option; do
  case "$option" in
    h) echo "$usage"
       exit
       ;;
    s) seed=$OPTARG
       ;;

• add local OPTIND OPTARG before calling getopts

I had a requirement to make a generic toString(Object obj) helper class function, where I had to convert the fieldnames into methodnames - getXXX() of the passed Object.

Here is the code

/**
 * @author DPARASOU
 * Utility method to replace the first char of a string with uppercase but leave other chars as it is.
 * ToString() 
 * @param inStr - String
 * @return String
 */
public static String firstCaps(String inStr)
{
    if (inStr != null && inStr.length() > 0)
    {
        char[] outStr = inStr.toCharArray();
        outStr[0] = Character.toUpperCase(outStr[0]);
        return String.valueOf(outStr);
    }
    else
        return inStr;
}

And my toString() utility is like this

public static String getToString(Object obj)
{
    StringBuilder toString = new StringBuilder();
    toString.append(obj.getClass().getSimpleName());
    toString.append("[");
    for(Field f : obj.getClass().getDeclaredFields())
    {
        toString.append(f.getName());
        toString.append("=");
        try{
            //toString.append(f.get(obj)); //access privilege issue
            toString.append(invokeGetter(obj, firstCaps(f.getName()), "get"));
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        toString.append(", ");        
    }
    toString.setCharAt(toString.length()-2, ']');
    return toString.toString();
}

Use the correct call: strptime is a classmethod of the datetime.datetime class, it's not a function in the datetime module.

self.date = datetime.datetime.strptime(self.d, "%Y-%m-%d")

As mentioned by Jon Clements in the comments, some people do from datetime import datetime, which would bind the datetime name to the datetime class, and make your initial code work.

To identify which case you're facing (in the future), look at your import statements

• import datetime: that's the module (that's what you have right now).
• from datetime import datetime: that's the class.

You can't disable a textbox in CSS. Disabling it is not a presentational task, you will have to do this in the HTML markup using the disabled attribute.

You may be able to put something together by putting the textbox underneath an absolutely positioned transparent element with z-index... But that's just silly, plus you would need a second HTML element anyway.

You can, however, style disabled text boxes (if that's what you mean) in CSS using

input[disabled] { ... }

from IE7 upwards and in all other major browsers.

This should do it:

<div id="wrap">
  <div id="nav"></div>
  <div id="content"></div>
  <div style="clear:both"></div>
</div>

A programmatic solution:

SELECT pg_encoding_to_char(encoding) FROM pg_database WHERE datname = 'yourdb';

Add a "User-Agent" header to your request.

Some servers attempt to block spidering programs and scrapers from accessing their server because, in earlier days, requests did not send a user agent header.

You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 Firefox/26.0"

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();

headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("user-agent", "Mozilla/5.0 Firefox/26.0");
headers.set("user-key", "your-password-123"); // optional - in case you auth in headers
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Game[]> respEntity = restTemplate.exchange(url, HttpMethod.GET, entity, Game[].class);

logger.info(respEntity.toString());

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

You want to use the NSDate compare:, laterDate:, earlierDate:, or isEqualToDate: methods. Using the < and > operators in this situation is comparing the pointers, not the dates

const char* byte_to_binary(int x)
{
    static char b[sizeof(int)*8+1] = {0};
    int y;
    long long z;

    for (z = 1LL<<sizeof(int)*8-1, y = 0; z > 0; z >>= 1, y++) {
        b[y] = (((x & z) == z) ? '1' : '0');
    }
    b[y] = 0;

    return b;
}

If you just want to throw the contents of the file onto the screen you can try using PHP.

<?php
    $myfilename = "mytextfile.txt";
    if(file_exists($myfilename)){
      echo file_get_contents($myfilename);
    }
?>

Below given some information about fav Icon

What Is FavIcon? ? FavIcon is nothing but small image which appears top left along with the application address bar title.Standard size specification for favicon.ico is 16 by 16 pixel. Please see below attached figure.

How It Works ? ? Usually we add our FavIcon.ico image in the route solution folder and automatically application picks it while running. But most of the time we might have to use below both link reference.

               <link rel="icon" href="favicon.ico" type="image/ico"/>
               <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"/>

Some browser expect one (rel="icon") Some other browser expect other rel="shortcut icon"

? Type=”image/x-icon” OR Type=”image/ico”: once expect exact ico image and one expect any image even formatted from .jpg or .pn ..etc.

? We have to use above two tags to the common pages like – Master page , Main frame which is getting used in all the pages

The following code is working for me with Java 7. I set the indent (yes) and indent-amount (2) on the transformer (not the transformer factory) to get it working.

TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
t.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
t.setOutputProperty(OutputKeys.INDENT, "yes");
t.transform(source, result);

@mabac's solution to set the attribute didn't work for me, but @lapo's comment proved helpful.

JSONObject(html).getString("name");

How to get the html String: Make an HTTP request with android

The LocalLinks extension from the most popular answer didn't work for me (given, I was trying to use file:// to open a directory in windows explorer, not a file), so I looked into another workaround. I found that this "Open in IE" extension is a good workaround: https://chrome.google.com/webstore/detail/open-in-ie/iajffemldkkhodaedkcpnbpfabiglmdi

This isn't an ideal fix, as instead of clicking the link, users will have to right-click and choose Open in IE, but it at least makes the link functional.

One thing to note though, in IE10 (and IE9 after a certain update point) you will have to add the site to your Trusted Sites (Internet Options > Security > Trusted sites). If the site is not in trusted sites, the file:// link does not work in IE either.

The best thing to do it is "Generate scripts for Drop"

Select Database -> Right Click -> Tasks -> Generate Scripts - will open wizard for generating scripts

after choosing objects in set Scripting option click Advanced Button

• -> Set option 'Script to create' to true (want to create)

• -> Set option 'Script to Drop' to true (want to drop)

• -> Select the Check box to select objects wish to create script

• -> Select the choice to write script (File, New window, Clipboard)

• It includes dependent objects by default.(and will drop constraint at first)

  Execute the script

This way we can customize our script.

I would simply make the assignment happen in the ng-mouseover and ng-mouseleave; no need to bother js file :)

<ul ng-repeat="task in tasks">
    <li ng-mouseover="hoverEdit = true" ng-mouseleave="hoverEdit = false">{{task.name}}</li>
    <span ng-show="hoverEdit"><a>Edit</a></span>
</ul>

I like the simple solution using windows functions:

select t.*
from (select student.*, su.subname, max(mark) over (partition by subid) as maxmark
      from marks m join
           students st
           on m.stid = st.stid join
           subject su
           on m.subid = su.subid
     ) t
where t.mark = maxmark

Or, alternatively:

select t.*
from (select student.*, su.subname, rank(mark) over (partition by subid order by mark desc) as markseqnum
      from marks m join
           students st
           on m.stid = st.stid join
           subject su
           on m.subid = su.subid
     ) t
where markseqnum = 1

Thanks to Siarhei Kuchuk for his post. Even tho I've simplified the usage this initial code was very useful for me.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

I was using CMake to compile my project and I've found the same problem.

The solution described here works like a charm, simply add ${CMAKE_DL_LIBS} to the target_link_libraries() call

Since you are using jQuery, you might as well use the each method... Also, it seems like everything is a value of the property 'd' in this JS Object [Notation].

$.each(result.d,function(i) {
    // In case there are several values in the array 'd'
    $.each(this,function(j) {
        // Apparently doesn't work...
        alert(this.EmployeeName);
        // What about this?
        alert(result.d[i][j]['EmployeeName']);
        // Or this?
        alert(result.d[i][j].EmployeeName);
    });
});

That should work. if not, then maybe you can give us a longer example of the JSON.

Edit: If none of this stuff works then I'm starting to think there might be something wrong with the syntax of your JSON.

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

One option is to use the filetype package.

Installation

python -m pip install filetype

2. Supports different mime type: Images, Videos, Fonts, Audio, Archives.

Example

filetype >= 1.0.7

import filetype

filename = "/path/to/file.jpg"

if filetype.is_image(filename):
    print(f"{filename} is a valid image...")
elif filetype.is_video(filename):
    print(f"{filename} is a valid video...")

filetype <= 1.0.6

import filetype

filename = "/path/to/file.jpg"

if filetype.image(filename):
    print(f"{filename} is a valid image...")
elif filetype.video(filename):
    print(f"{filename} is a valid video...")

style is accordingly vis css. An example

<h1 class="mynotsoboldtitle">Im not bold</h1>
<style>
.mynotsoboldtitle { font-weight:normal; }
</style>

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

I don't think the order can be guaranteed, otherwise it would be easy enough to slice the second half of Object.entries result and map from there.

The only (very minor) issues with the answers above is that

• there is a lot of unnecessary type conversion between string and number.
• the entries are iterated twice when a single iteration is just as clean and effective.

type StandardEnum = { [id: string]: number | string; [nu: number]: string;}

function enumToList<T extends StandardEnum> (enm: T) : { id: number; description: string }[] {
    return Object.entries(enm).reduce((accum, kv) => {
        if (typeof kv[1] === 'number') {
            accum.push({ id: kv[1], description: kv[0] })
        }
        return accum
    }, []) // if enum is huge, perhaps pre-allocate with new Array(entries.length / 2), however then push won't work, so tracking an index would also be required
}

You should use the substring() method of String object.

Here is an example code:

Assumption: I am assuming here that you want to retrieve the string till the first parenthesis

String strTest = "manchester united(with nice players)";
/*Get the substring from the original string, with starting index 0, and ending index as position of th first parenthesis - 1 */
String strSub = strTest.subString(0,strTest.getIndex("(")-1);

For myself, using Jquery lib 2.1.1 the following did NOT work the way I expected:

Set element data attribute value:

$('.my-class').data('num', 'myValue');
console.log($('#myElem').data('num'));// as expected = 'myValue'

BUT the element itself remains without the attribute:

<div class="my-class"></div>

I needed the DOM updated so I could later do $('.my-class[data-num="myValue"]') //current length is 0

So I had to do

$('.my-class').attr('data-num', 'myValue');

To get the DOM to update:

<div class="my-class" data-num="myValue"></div>

Whether the attribute exists or not $.attr will overwrite.

I think this issue following model class wrong import.

    import org.springframework.data.annotation.Id;

Normally, it should be:

    import javax.persistence.Id;

LDAPService should contain method like LDAPService.isExists(String userName) use it to prevent NPE to be thrown. If is not - this could be a workaround, but use Logging to post some warning..

In addition to how Java defines static inner classes, there is another definition of static classes as per the C# world [1]. A static class is one that has only static methods (functions) and it is meant to support procedural programming. Such classes aren't really classes in that the user of the class is only interested in the helper functions and not in creating instances of the class. While static classes are supported in C#, no such direct support exists in Java. You can however use enums to mimic C# static classes in Java so that a user can never create instances of a given class (even using reflection) [2]:

public enum StaticClass2 {
    // Empty enum trick to avoid instance creation
    ; // this semi-colon is important

    public static boolean isEmpty(final String s) {
        return s == null || s.isEmpty();
    }
}

Since you are using $.ajax, and not $.getJSON, your return type is plain text. you need to now convert data into a JSON object.

you can either do this by changing your $.ajax to $.getJSON (which is a shorthand for $.ajax, only preconfigured to fetch json).

Or you can parse the data string into JSON after you receive it, like so:

    success: function (data) {
         var obj = $.parseJSON(data);
         console.log(obj);
    },

I placed the button group inside the title, and then added a clearfix to the bottom.

<div class="panel-heading">
  <h4 class="panel-title">
    Panel header
    <div class="btn-group pull-right">
      <a href="#" class="btn btn-default btn-sm">## Lock</a>
      <a href="#" class="btn btn-default btn-sm">## Delete</a>
      <a href="#" class="btn btn-default btn-sm">## Move</a>
    </div>
  </h4>
  <div class="clearfix"></div>
</div>

Another example for vertically and horizontally centered div or any object(s):

 var obj = $("#divID");
 var halfsc = $(window).height()/2;
 var halfh = $(obj).height() / 2; 

 var halfscrn = screen.width/2;
 var halfobj =$(obj).width() / 2; 

 var goRight =  halfscrn - halfobj ;
 var goBottom = halfsc - halfh;

 $(obj).css({marginLeft: goRight }).css({marginTop: goBottom });

The OP added in his question:

the files checked out using msysgit are using CR+LF and I want to force msysgit to get them with LF

A first simple step would still be in a .gitattributes file:

# 2010
*.txt -crlf

# 2020
*.txt text eol=lf 

(as noted in the comments by grandchild, referring to .gitattributes End-of-line conversion), to avoid any CRLF conversion for files with correct eol.

And I have always recommended git config --global core.autocrlf false to disable any conversion (which would apply to all versioned files)

See Best practices for cross platform git config?

Since Git 2.16 (Q1 2018), you can use git add --renormalize . to apply those .gitattributes settings immediately.

But a second more powerful step involves a gitattribute filter driver and add a smudge step

Whenever you would update your working tree, a script could, only for the files you have specified in the .gitattributes, force the LF eol and any other formatting option you want to enforce.
If the "clear" script doesn't do anything, you will have (after commit) transformed your files, applying exactly the format you need them to follow.

As of jsdom v10, .env() function is deprecated. I did it like below after trying a lot of things to require jquery:

var jsdom = require('jsdom');_x000D_
const { JSDOM } = jsdom;_x000D_
const { window } = new JSDOM();_x000D_
const { document } = (new JSDOM('')).window;_x000D_
global.document = document;_x000D_
_x000D_
var $ = jQuery = require('jquery')(window);

Hope this helps you or anyone who has been facing these types of issues.

I know this is a bit late, but I'm having a similar issue. SQL*Plus executes the query successfully, but Oracle SQL Developer shows the ORA-01843: not a valid month error.

SQL*Plus seems to know that the date I'm using is in the valid format, whereas Oracle SQL Developer needs to be told explicitly what format my date is in.

• SQL*Plus statement:

  select count(*) from some_table where DATE_TIME_CREATED < '09-12-23';
  

VS

• Oracle SQL Developer statement:

   select count(*) from some_table where DATE_TIME_CREATED < TO_DATE('09-12-23','RR-MM-DD');
  

Same thing happened to me on Pixelbook using the new LXC (strech). This solution is very similar to the accepted one, with one subtle difference, whiched fixed pip3 for me.

sudo python3 -m pip install --upgrade pip

That bumped the version, and now it works as expected.

I found it here ... Python.org: Ensure pip is up-to-date

I faced same issue while using Python 3.9.0. Upgrading python to latest version (currently 3.9.1) and reinstalling opencv-python solved this issue.

The blog post you quoted overstates its claim a bit. FP doesn't eliminate the need for design patterns. The term "design patterns" just isn't widely used to describe the same thing in FP languages. But they exist. Functional languages have plenty of best practice rules of the form "when you encounter problem X, use code that looks like Y", which is basically what a design pattern is.

However, it's correct that most OOP-specific design patterns are pretty much irrelevant in functional languages.

I don't think it should be particularly controversial to say that design patterns in general only exist to patch up shortcomings in the language. And if another language can solve the same problem trivially, that other language won't have need of a design pattern for it. Users of that language may not even be aware that the problem exists, because, well, it's not a problem in that language.

Here is what the Gang of Four has to say about this issue:

The choice of programming language is important because it influences one's point of view. Our patterns assume Smalltalk/C++-level language features, and that choice determines what can and cannot be implemented easily. If we assumed procedural languages, we might have included design patterns called "Inheritance", "Encapsulation," and "Polymorphism". Similarly, some of our patterns are supported directly by the less common object-oriented languages. CLOS has multi-methods, for example, which lessen the need for a pattern such as Visitor. In fact, there are enough differences between Smalltalk and C++ to mean that some patterns can be expressed more easily in one language than the other. (See Iterator for example.)

(The above is a quote from the Introduction to the Design Patterns book, page 4, paragraph 3)

The main features of functional programming include functions as first-class values, currying, immutable values, etc. It doesn't seem obvious to me that OO design patterns are approximating any of those features.

What is the command pattern, if not an approximation of first-class functions? :) In an FP language, you'd simply pass a function as the argument to another function. In an OOP language, you have to wrap up the function in a class, which you can instantiate and then pass that object to the other function. The effect is the same, but in OOP it's called a design pattern, and it takes a whole lot more code. And what is the abstract factory pattern, if not currying? Pass parameters to a function a bit at a time, to configure what kind of value it spits out when you finally call it.

So yes, several GoF design patterns are rendered redundant in FP languages, because more powerful and easier to use alternatives exist.

But of course there are still design patterns which are not solved by FP languages. What is the FP equivalent of a singleton? (Disregarding for a moment that singletons are generally a terrible pattern to use.)

And it works both ways too. As I said, FP has its design patterns too; people just don't usually think of them as such.

But you may have run across monads. What are they, if not a design pattern for "dealing with global state"? That's a problem that's so simple in OOP languages that no equivalent design pattern exists there.

We don't need a design pattern for "increment a static variable", or "read from that socket", because it's just what you do.

Saying a monad is a design pattern is as absurd as saying the Integers with their usual operations and zero element is a design pattern. No, a monad is a mathematical pattern, not a design pattern.

In (pure) functional languages, side effects and mutable state are impossible, unless you work around it with the monad "design pattern", or any of the other methods for allowing the same thing.

Additionally, in functional languages which support OOP (such as F# and OCaml), it seems obvious to me that programmers using these languages would use the same design patterns found available to every other OOP language. In fact, right now I use F# and OCaml everyday, and there are no striking differences between the patterns I use in these languages vs the patterns I use when I write in Java.

Perhaps because you're still thinking imperatively? A lot of people, after dealing with imperative languages all their lives, have a hard time giving up on that habit when they try a functional language. (I've seen some pretty funny attempts at F#, where literally every function was just a string of 'let' statements, basically as if you'd taken a C program, and replaced all semicolons with 'let'. :))

But another possibility might be that you just haven't realized that you're solving problems trivially which would require design patterns in an OOP language.

When you use currying, or pass a function as an argument to another, stop and think about how you'd do that in an OOP language.

Is there any truth to the claim that functional programming eliminates the need for OOP design patterns?

Yep. :) When you work in a FP language, you no longer need the OOP-specific design patterns. But you still need some general design patterns, like MVC or other non-OOP specific stuff, and you need a couple of new FP-specific "design patterns" instead. All languages have their shortcomings, and design patterns are usually how we work around them.

Anyway, you may find it interesting to try your hand at "cleaner" FP languages, like ML (my personal favorite, at least for learning purposes), or Haskell, where you don't have the OOP crutch to fall back on when you're faced with something new.

As expected, a few people objected to my definition of design patterns as "patching up shortcomings in a language", so here's my justification:

As already said, most design patterns are specific to one programming paradigm, or sometimes even one specific language. Often, they solve problems that only exist in that paradigm (see monads for FP, or abstract factories for OOP).

Why doesn't the abstract factory pattern exist in FP? Because the problem it tries to solve does not exist there.

So, if a problem exists in OOP languages, which does not exist in FP languages, then clearly that is a shortcoming of OOP languages. The problem can be solved, but your language does not do so, but requires a bunch of boilerplate code from you to work around it. Ideally, we'd like our programming language to magically make all problems go away. Any problem that is still there is in principle a shortcoming of the language. ;)

You could just use this

FileOpen(1, "C:\my files\2010\SomeFileName.txt", OpenMode.Output)
FileClose(1)

This opens the file replaces whatever is in it and closes the file.

its very simple

just write:

//first create table named test....

create table test (name varchar2(10),age number(5));

//when you run the above code a table will be created....

//now we have to insert a name & an age..

Make sure age will be inserted via opening a form that seeks our help to enter the value in it

insert into test values('Deepak', :age);

//now run the above code and you'll get "1 row inserted" output...

/now run the select query to see the output

select * from test;

//that's all ..Now i think no one has any queries left over accepting a user data...

You can use

np.tile(x,3).reshape((4,3))

tile will generate the reps of the vector

and reshape will give it the shape you want

The following works for me :-)

/////////////////////////////////////////////////////////////////////////////////////

Here is another reason the console may disappear. And the solution:

With the new Visual Studio 2010 you might see this behavior even when you use Ctrl + F5 aka "start without debugging". This is most likely because you created an "empty project" instead of a "Win32 console application". If you create the project as a "Win32 console application" you can disregard this as it does not apply.

In the older versions it would default to the console subsystem even if you selected "empty project", but not in Visual Studio 2010, so you have to set it manually. To do this select the project in the solution explorer on the right or left (probably is already selected so you don't have to worry about this).

Then select "project" from the menu bar drop down menus, then select "project_name properties" ? "configuration properties" ? "linker" ? "system" and set the first property, the drop down "subsystem" property to "console (/SUBSYSTEM:CONSOLE)". The console window should now stay open after execution as usual.

/////////////////////////////////////////////////////////////////////////////////////

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

On Windows this should work (note the forwardslash and that the whole path is not quoted and that spaces are allowed)

Here is my final solution. It works fine with a large amount of data. I use Timer to make sure the user want find current value. It looks like complex but it doesn't. Thanks to Max Lambertini for the idea.

        private bool _canUpdate = true; 

        private bool _needUpdate = false;       

        //If text has been changed then start timer
        //If the user doesn't change text while the timer runs then start search
        private void combobox1_TextChanged(object sender, EventArgs e)
        {
            if (_needUpdate)
            {
                if (_canUpdate)
                {
                    _canUpdate = false;
                    UpdateData();                   
                }
                else
                {
                    RestartTimer();
                }
            }
        }

        private void UpdateData()
        {
            if (combobox1.Text.Length > 1)
            {
                List<string> searchData = Search.GetData(combobox1.Text);
                HandleTextChanged(searchData);
            }
        }       

        //If an item was selected don't start new search
        private void combobox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            _needUpdate = false;
        }

        //Update data only when the user (not program) change something
        private void combobox1_TextUpdate(object sender, EventArgs e)
        {
            _needUpdate = true;
        }

        //While timer is running don't start search
        //timer1.Interval = 1500;
        private void RestartTimer()
        {
            timer1.Stop();
            _canUpdate = false;
            timer1.Start();
        }

        //Update data when timer stops
        private void timer1_Tick(object sender, EventArgs e)
        {
            _canUpdate = true;
            timer1.Stop();
            UpdateData();
        }

        //Update combobox with new data
        private void HandleTextChanged(List<string> dataSource)
        {
            var text = combobox1.Text;

            if (dataSource.Count() > 0)
            {
                combobox1.DataSource = dataSource;  

                var sText = combobox1.Items[0].ToString();
                combobox1.SelectionStart = text.Length;
                combobox1.SelectionLength = sText.Length - text.Length;
                combobox1.DroppedDown = true;


                return;
            }
            else
            {
                combobox1.DroppedDown = false;
                combobox1.SelectionStart = text.Length;
            }
        }

This solution isn't very cool. So if someone has another solution please share it with me.

This might work for you

public void save(String fileName) throws FileNotFoundException {
FileOutputStream fout= new FileOutputStream (fileName);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(clubs);
fout.close();
}

To read back you can have

public void read(String fileName) throws FileNotFoundException {
FileInputStream fin= new FileInputStream (fileName);
ObjectInputStream ois = new ObjectInputStream(fin);
clubs= (ArrayList<Clubs>)ois.readObject();
fin.close();
}

Here ya go..

    List<string> list = new List<string>() { "1", "2", "3" };
    List<string> remove = new List<string>() { "2" };

    list.ForEach(s =>
        {
            if (remove.Contains(s))
            {
                list.Remove(s);
            }
        });

I ran into a similar bind in a render function and ended up passing the context of this in the following way:

{someList.map(function(listItem) {
  // your code
}, this)}

I've also used:

{someList.map((listItem, index) =>
    <div onClick={this.someFunction.bind(this, listItem)} />
)}

The source tree you are requiring is still available within the git repository, however, you will need the SHA1 of the commit that you are interested in. I would assume that you can get the SHA1 from the current clone you have?

If you can get that SHA1, the you can create a branch / reset there to have the identical repository.

Commands as per Rui's answer

Regarding the upvoted answer, I liked it except that if the resulting "listfiles" array is used in an array formula {CSE}, the list values come out all in a horizontal row. To make them come out in a vertical column, I simply made the array two dimensional as follows:

ReDim vaArray(1 To oFiles.Count, 0)
i = 1
For Each oFile In oFiles
    vaArray(i, 0) = oFile.Name
    i = i + 1

In kotlin you can call activity method from fragment like below:

var mainActivity: MainActivity = activity as MainActivity
        mainActivity.showToast() //Calling show toast method of activity

This constructor was deprecated in API level 26.1.0. use NotificationCompat.Builder(Context, String) instead. All posted Notifications must specify a NotificationChannel Id.

One of the most elegant solutions was here Get characters after last / in url

by DisgruntledGoat

$id = substr($url, strrpos($url, '/') + 1);

strrpos gets the position of the last occurrence of the slash; substr returns everything after that position.

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

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

My current solution uses the async module to execute in series:

var fs = require('fs');
var parse = require('csv-parse');
var async = require('async');

var inputFile='myfile.csv';

var parser = parse({delimiter: ','}, function (err, data) {
  async.eachSeries(data, function (line, callback) {
    // do something with the line
    doSomething(line).then(function() {
      // when processing finishes invoke the callback to move to the next one
      callback();
    });
  })
});
fs.createReadStream(inputFile).pipe(parser);

In C#, the common mutex used is the Monitor. The type is 'System.Threading.Monitor'. It may also be used implicitly via the 'lock(Object)' statement. One example of its use is when constructing a Singleton class.

private static readonly Object instanceLock = new Object();
private static MySingleton instance;
public static MySingleton Instance
{
    lock(instanceLock)
    {
        if(instance == null)
        {
            instance = new MySingleton();
        }
        return instance;
    }
}

The lock statement using the private lock object creates a critical section. Requiring each thread to wait until the previous is finished. The first thread will enter the section and initialize the instance. The second thread will wait, get into the section, and get the initialized instance.

Any sort of synchronization of a static member may use the lock statement similarly.

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

Two Method

• using homebrew auto install:
  • Steps:
    • brew install gradle
  • Pros and cons
    • Pros: easy
    • Cons: (probably) not latest version
• manually install (for latest version):
  • Pros and cons
    • Pros: use your expected any (or latest) version
    • Cons: need self to do it
  • Steps
    • download latest version binary (gradle-6.0.1) from Gradle | Releases
    • unzip it (gradle-6.0.1-all.zip) and added gradle path into environment variable PATH
      • normally is edit and add following config into your startup script( ~/.bashrc or ~/.zshrc etc.):

export GRADLE_HOME=/path_to_your_gradle/gradle-6.0.1
export PATH=$GRADLE_HOME/bin:$PATH

some other basic note

Q: How to make PATH take effect immediately?

A: use source:

source ~/.bashrc

it will make/execute your .bashrc, so make PATH become your expected latest values, which include your added gradle path.

Q: How to check PATH is really take effect/working now?

A: use echo to see your added path in indeed in your PATH

?  ~ echo $PATH
xxx:/Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin:xxx

you can see we added /Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin into your PATH

Q: How to verify gradle is installed correctly on my Mac ?

A: use which to make sure can find gradle

?  ~ which gradle
/Users/crifan/dev/dev_tool/java/gradle/gradle-6.0.1/bin/gradle

AND to check and see gradle version

?  ~ gradle --version

Try $('#score_here').html=total;

string1.equals(string2) is right way to do it.

String s = "something", t = "maybe something else";
 if (s == t)      // Legal, but usually results WRONG.
 if (s.equals(t)) // RIGHT way to check the two strings
  /* == will fail in following case:*/
 String s1 = new String("abc");
 String s2 = new String("abc");

 if(s1==s2) //it will return false

Yes. There are two kinds of types in .NET: reference types and value types.

References types (generally classes) are always referred to by references, so they support null without any extra work. This means that if a variable's type is a reference type, the variable is automatically a reference.

Value types (e.g. int) by default do not have a concept of null. However, there is a wrapper for them called Nullable. This enables you to encapsulate the non-nullable value type and include null information.

The usage is slightly different, though.

// Both of these types mean the same thing, the ? is just C# shorthand.
private void Example(int? arg1, Nullable<int> arg2)
{
    if (arg1.HasValue)
        DoSomething();

    arg1 = null; // Valid.
    arg1 = 123;  // Also valid.

    DoSomethingWithInt(arg1); // NOT valid!
    DoSomethingWithInt(arg1.Value); // Valid.
}

I am using Android Studio 3.3.

Go to View -> Tools Window -> Device File Explorer. Or you can find it on the Bottom Right corner of the Android Studio.

If the Emulator is running, the Device File Explorer will display the File structure on Emulator Storage.

Here you can right click on a Folder and select "Upload" to place the file

tx, found the workaround I needed:

  constructor(private zone:NgZone) {
    // enable to for time travel
    this.appStore.subscribe((state) => {
        this.zone.run(() => {
            console.log('enabled time travel');
        });
    });

running zone.run will force the component to re-render

If you mean the array indexer,, You overload that just by writing an indexer property.. And you can overload, (write as many as you want) indexer properties as long as each one has a different parameter signature

public class EmployeeCollection: List<Employee>
{
    public Employee this[int employeeId]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.EmployeeId == employeeId)
                    return emp;
            }

            return null;
        }
    }

    public Employee this[string employeeName]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.Name == employeeName)
                    return emp;
            }

            return null;
        }
    }
}

You can find what is the php.ini file used:

• By add phpinfo() in a php page and display the page (like the picture under)
• From the shell, enter: php -i

Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)

Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

I hope this answer will help.

I found this question while googling for a way to auto-format phone numbers via a jQuery plugin. The accepted answer was not ideal for my needs and a lot has happened in the 6 years since it was originally posted. I eventually found the solution and am documenting it here for posterity.

Problem

I would like my phone number html input field to auto-format (mask) the value as the user types.

Solution

Check out Cleave.js. It is a very powerful/flexible and easy way to solve this problem, and many other data masking issues.

Formatting a phone number is as easy as:

var cleave = new Cleave('.input-element', {
    phone: true,
    phoneRegionCode: 'US'
});

The best way to fix this:

Renew the certificate. This can be done for free using Greenlock which issues certificates via Let's Encrypt™ v2

A less insecure way to fix this:

'use strict';

var request = require('request');
var agentOptions;
var agent;

agentOptions = {
  host: 'www.example.com'
, port: '443'
, path: '/'
, rejectUnauthorized: false
};

agent = new https.Agent(agentOptions);

request({
  url: "https://www.example.com/api/endpoint"
, method: 'GET'
, agent: agent
}, function (err, resp, body) {
  // ...
});

By using an agent with rejectUnauthorized you at least limit the security vulnerability to the requests that deal with that one site instead of making your entire node process completely, utterly insecure.

Other Options

If you were using a self-signed cert you would add this option:

agentOptions.ca = [ selfSignedRootCaPemCrtBuffer ];

For trusted-peer connections you would also add these 2 options:

agentOptions.key = clientPemKeyBuffer;
agentOptions.cert = clientPemCrtSignedBySelfSignedRootCaBuffer;

Bad Idea

It's unfortunate that process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0'; is even documented. It should only be used for debugging and should never make it into in sort of code that runs in the wild. Almost every library that runs atop https has a way of passing agent options through. Those that don't should be fixed.

this example, I am assuming that all your image files begin with "IMG" and you want to replace "IMG" with "VACATION"

solution : first identified all jpg files and then replace keyword

find . -name '*jpg' -exec bash -c 'echo mv $0 ${0/IMG/VACATION}' {} \; 

Answer by Adamski is a good one and describes the steps in an encoding operation when using the general encode method (that takes a byte buffer as one of the inputs)

However, the method in question (in this discussion) is a variant of encode - encode(CharBuffer in). This is a convenience method that implements the entire encoding operation. (Please see java docs reference in P.S.)

As per the docs, This method should therefore not be invoked if an encoding operation is already in progress (which is what is happening in ZenBlender's code -- using static encoder/decoder in a multi threaded environment).

Personally, I like to use convenience methods (over the more general encode/decode methods) as they take away the burden by performing all the steps under the covers.

ZenBlender and Adamski have already suggested multiple ways options to safely do this in their comments. Listing them all here:

• Create a new encoder/decoder object when needed for each operation (not efficient as it could lead to a large number of objects). OR,
• Use a ThreadLocal to avoid creating new encoder/decoder for each operation. OR,
• Synchronize the entire encoding/decoding operation (this might not be preferred unless sacrificing some concurrency is ok for your program)

P.S.

java docs references:

1. Encode (convenience) method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer%29
2. General encode method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer,%20java.nio.ByteBuffer,%20boolean%29

In Identity inspector change class name with the corresponding identifier and also In Attributes inspector modify Indentifier then it should work as expected.

To make background transparent, set shape as None. See the image below:

EDIT:

For Android Studio 3.0, you can set it from Legacy Tab

I found the following codes work perfectly for the job.

fig = plt.figure(figsize=[6,6])
ax = fig.add_subplot(111)
ax.imshow(data)
ax.axes.get_xaxis().set_visible(False)
ax.axes.get_yaxis().set_visible(False)
ax.set_frame_on(False)
plt.savefig('data.png', dpi=400, bbox_inches='tight',pad_inches=0)

I'd just use zip:

In [1]: from pandas import *

In [2]: def calculate(x):
   ...:     return x*2, x*3
   ...: 

In [3]: df = DataFrame({'a': [1,2,3], 'b': [2,3,4]})

In [4]: df
Out[4]: 
   a  b
0  1  2
1  2  3
2  3  4

In [5]: df["A1"], df["A2"] = zip(*df["a"].map(calculate))

In [6]: df
Out[6]: 
   a  b  A1  A2
0  1  2   2   3
1  2  3   4   6
2  3  4   6   9

I generally prefer to add these codes in a function to get the Android version:

int whichAndroidVersion;

whichAndroidVersion= Build.VERSION.SDK_INT;
textView.setText("" + whichAndroidVersion); //If you don't use "" then app crashes.

For example, that code above will set the text into my textView as "29" now.

As you are reading the binary file, you need to unpack it into a integer, so use struct module for that

import struct
fin = open("hi.bmp", "rb")
firm = fin.read(2)  
file_size, = struct.unpack("i",fin.read(4))
