Most Android and iPhone apps I have seen use an initial screen or dialog box to ask for credentials. I think it is cumbersome for the user to have to re-enter their name/password often, so storing that info makes sense from a usability perspective.

The advice from the (Android dev guide) is:

In general, we recommend minimizing the frequency of asking for user credentials -- to make phishing attacks more conspicuous, and less likely to be successful. Instead use an authorization token and refresh it.

Where possible, username and password should not be stored on the device. Instead, perform initial authentication using the username and password supplied by the user, and then use a short-lived, service-specific authorization token.

Using the AccountManger is the best option for storing credentials. The SampleSyncAdapter provides an example of how to use it.

If this is not an option to you for some reason, you can fall back to persisting credentials using the Preferences mechanism. Other applications won't be able to access your preferences, so the user's information is not easily exposed.

2019 Update

This updates the answers with the latest Fetch API and doesn't need jQuery.

Disclaimer: doesn't work on IE, Opera Mini and older browsers. See caniuse.

Basic Fetch

It could be as simple as:

  fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
                .then(response => console.log(response.text()))

Fetch with Error Handling

After adding error handling, it could look like:

fetch(`https://example.com/upload.php`, {method:"POST", body:blobData})
            .then(response => {
                if (response.ok) return response;
                else throw Error(`Server returned ${response.status}: ${response.statusText}`)
            })
            .then(response => console.log(response.text()))
            .catch(err => {
                alert(err);
            });

PHP Code

This is the server-side code in upload.php.

<?php    
    // gets entire POST body
    $data = file_get_contents('php://input');
    // write the data out to the file
    $fp = fopen("path/to/file", "wb");

    fwrite($fp, $data);
    fclose($fp);
?>

Try this function...

function calculate_age(birth_month,birth_day,birth_year)
{
    today_date = new Date();
    today_year = today_date.getFullYear();
    today_month = today_date.getMonth();
    today_day = today_date.getDate();
    age = today_year - birth_year;

    if ( today_month < (birth_month - 1))
    {
        age--;
    }
    if (((birth_month - 1) == today_month) && (today_day < birth_day))
    {
        age--;
    }
    return age;
}

OR

function getAge(dateString) 
{
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) 
    {
        age--;
    }
    return age;
}

See Demo.

simply use local time as the default:

CREATE TABLE whatever(
     ....
     timestamp DATE DEFAULT (datetime('now','localtime')),
     ...
);

The underscore js way -

var a = "1,2,3,4",
  b = a.split(',');

//remove falsy/empty values from array after split
b = _.compact(b);
//then Convert array of string values into Integer
b = _.map(b, Number);

console.log('Log String to Int conversion @b =', b);

I have created a javascript function that looks if he has enough space on the right side. If it has he will show it on the right side, else he will display it on the left side

Tested in:

• Firefox (mac)
• Chorme (mac)
• Safari (mac)

Javascript:

$(document).ready(function(){
    //little fix for the poisition.
    var newPos     = $(".fixed-menuprofile .dropdown-submenu").offset().left - $(this).width();
    $(".fixed-menuprofile .dropdown-submenu").find('ul').offset({ "left": newPos });

    $(".fixed-menu .dropdown-submenu").mouseover(function() {
        var submenuPos = $(this).offset().left + 325;
        var windowPos  = $(window).width();
        var oldPos     = $(this).offset().left + $(this).width();
        var newPos     = $(this).offset().left - $(this).width();

        if( submenuPos > windowPos ){
            $(this).find('ul').offset({ "left": newPos });
        } else {
            $(this).find('ul').offset({ "left": oldPos });
        }
    });
});

because I don't want to add this fix on every menu items I created a new class on it. place the fixed-menu on the ul:

<ul class="dropdown-menu fixed-menu">

I hope this works out for you.

ps. little bug in safari and chrome, first hover will place it to mutch to the left will update this post if I fixed it.

Right click on project - >BuildPath - >Configure BuildPath - >Libraries tab - >

Double click on JRE SYSTEM LIBRARY - >Then select alternate JRE

Yet another way is to read the composer.json file, but it can end with wildcard character *

var a = new Date("2010 jan 10"),
    b = new Date("2010 jan 9");

alert(
    a + "\n" + 
    b + "\n" +
    "Difference: " + ((+a - +b) / 1000)
);

this

    SELECT field,datetime_field 
FROM database
WHERE datetime_field > (sysdate-1)

will work. The question is: is the 'datetime_field' has the same format as sysdate ? My way to handle that: use 'to_char()' function (only works in Oracle).

samples: previous day:

select your_column
from your_table
where to_char(sysdate-1, 'dd.mm.yyyy')

or

select extract(day from date_field)||'/'|| 
       extract(month from date_field)||'/'||
       extract(year from date_field)||'/'||
as mydate
from dual(or a_table)
where extract(day from date_field) = an_int_number and
      extract(month from date_field) = an_int_number and so on..

comparing date:

select your_column
from your_table
where
to_char(a_datetime_column, 'dd.mm.yyyy') > or < or >= or <= to_char(sysdate, 'dd.mm.yyyy')

time range between yesterday and a day before yesterday:

select your_column
from your_table
where
to_char(a_datetime_column, 'dd.mm.yyyy') > or < or >= or <= to_char(sysdate-1, 'dd.mm.yyyy') and
to_char(a_datetime_column, 'dd.mm.yyyy') > or < or >= or <= to_char(sysdate-2, 'dd.mm.yyyy')

other time range variation

select your_column
from your_table
where 
to_char(a_datetime_column, 'dd.mm.yyyy') is between to_char(sysdate-1, 'dd.mm.yyyy') 
and to_char(sysdate-2, 'dd.mm.yyyy')

java.util.Calendar is the usual way to handle time zones using just JDK classes. Apache Commons has some further alternatives/utilities that may be helpful. Edit Spong's note reminded me that I've heard really good things about Joda-Time (though I haven't used it myself).

In case anyone else is running in to the same problem, the only solution I could find that satisfied me was to have the canvas cover everything and then to raise the Z-index of all clickable elements. You can't draw on them, but at least they are clickable...

I'm assuming from the way you worded the question that you want to change the size after the page has rendered?

In Javascript, you can manipulate DOM CSS properties, for example:

document.getElementById('textboxid').style.height="200px";
document.getElementById('textboxid').style.fontSize="14pt";

If you simply want to specify the height and font size, use CSS or style attributes, e.g.

//in your CSS file or <style> tag
#textboxid
{
    height:200px;
    font-size:14pt;
}

<!--in your HTML-->
<input id="textboxid" ...>

Or

<input style="height:200px;font-size:14pt;" .....>

In my case, I'm receiving several parameters as @HeaderParam into a web service method.

These parameters MUST be declared in your CORS filter that way:

@Provider
public class CORSFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) throws IOException {

        MultivaluedMap<String, Object> headers = responseContext.getHeaders();

        headers.add("Access-Control-Allow-Origin", "*");
        ...
        headers.add("Access-Control-Allow-Headers", 
        /*
         * name of the @HeaderParam("name") must be declared here (raw String):
         */
        "name", ...);
        headers.add("Access-Control-Allow-Credentials", "true");
        headers.add("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");   
    }
}

This discussion helped me resolve the issue I was struggling with for days. I looked around all over the internet until I found the answered by Jim Tough on May 18 '11 at 15:17. With that answer I was able to connect. Now I want to give back and help others with a complete example. Here goes:

import java.sql.*; 

public class MyDBConnect {

    public static void main(String[] args) throws SQLException {

        try { 
            String dbURL = "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=whatEverYourHostNameIs)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=yourServiceName)))";
            String strUserID = "yourUserId";
            String strPassword = "yourPassword";
            Connection myConnection=DriverManager.getConnection(dbURL,strUserID,strPassword);

            Statement sqlStatement = myConnection.createStatement();
            String readRecordSQL = "select * from sa_work_order where WORK_ORDER_NO = '1503090' ";  
            ResultSet myResultSet = sqlStatement.executeQuery(readRecordSQL);
            while (myResultSet.next()) {
                System.out.println("Record values: " + myResultSet.getString("WORK_ORDER_NO"));
            }
            myResultSet.close();
            myConnection.close();

        } catch (Exception e) {
            System.out.println(e);
        }       
    }
}

In your question it seems that you have span selector with given to every span a seperate class into ul li option and then you have many answers, i.e.

$(document).ready(function()
 {
   $('ul.art-vmenu li').click(function(e) 
    { 
     alert($(this).find("span.t").text());
   });
});

But you need not to use ul.art-vmenu li rather you can use direct ul with the use of on as used in below example :

$(document).ready(function()
 {
  $("ul.art-vmenu").on("click","li", function(){
     alert($(this).find("span.t").text());
  });
});

Mutable means you will save the same reference to variable and change its contents but immutable you can not change contents but you will declare new reference contains the new and the old value of the variable

Ex Immutable -> String

String x = "value0ne";// adresse one x += "valueTwo"; //an other adresse {adresse two} adresse on the heap memory change.

Mutable -> StringBuffer - StringBuilder StringBuilder sb = new StringBuilder(); sb.append("valueOne"); // adresse One sb.append("valueTwo"); // adresse One

sb still in the same adresse i hope this comment helps

Controlling the order of tabbing (pressing the tab key to move focus) within the page.

Reference: http://www.w3.org/TR/html401/interact/forms.html#h-17.11.1

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

Up-to-date for 2021

It is one of the silliest bugs in iOS.

The class given here, UITextViewFixed , is used widely, and is usually the most reasonable solution overall.

Here is the class:

@IBDesignable class UITextViewFixed: UITextView {
    override func layoutSubviews() {
        super.layoutSubviews()
        setup()
    }
    func setup() {
        textContainerInset = UIEdgeInsets.zero
        textContainer.lineFragmentPadding = 0
    }
}

Don't forget to turn off scrollEnabled in the Inspector!

1. The solution works properly in storyboard

2. The solution works properly at runtime

That's it, you're done.

In general, that should be all you need in most cases.

Even if you are changing the height of the text view on the fly, UITextViewFixed usually does all you need.

(A common example of changing the height on the fly, is changing it as the user types.)

Here is the broken UITextView from Apple...

Here is UITextViewFixed:

Note that of course you must...

...turn off scrollEnabled in the Inspector!

(Turning on scrollEnabled means "make this view expand as much as possible vertically by expanding the bottom margin as much as possible.")

Some further issues

(1) In some very unusual cases dynamically changing heights, Apple does a bizarre thing: they add extra space at the bottom.

No, really! This would have to be one of the most infuriating things in iOS.

If you encounter the problem, here is a "quick fix" which usually helps:

...
        textContainerInset = UIEdgeInsets.zero
        textContainer.lineFragmentPadding = 0
       
        // this is not ideal, but sometimes this "quick fix"
        // will solve the "extra space at the bottom" insanity:
        var b = bounds
        let h = sizeThatFits(CGSize(
           width: bounds.size.width,
           height: CGFloat.greatestFiniteMagnitude)
       ).height
       b.size.height = h
       bounds = b
 ...

(2) In rare cases, to fix yet another subtle mess-up by Apple, you have to add:

override func setContentOffset(_ contentOffset: CGPoint, animated: Bool) {
    super.setContentOffset(contentOffset, animated: false) // sic
}

(3) Arguably, we should be adding :

contentInset = UIEdgeInsets.zero

just after .lineFragmentPadding = 0 in UITextViewFixed .

However ... believe or not ... that just doesn't work in current iOS! (Checked 2021.) It may be necessary to add that line in the future.

The fact that UITextView is broken in iOS is one of the weirdest things in all of mobile computing. Ten year anniversary of this question and it's still not fixed!

Finally, here's a somewhat similar tip for TextField: https://stackoverflow.com/a/43099816/294884

Completely random tip: how to add the "..." on the end

Often you are using a UITextView "like a UILabel". So you want it to truncate text using an ellipsis "..."

If so, add:

 textContainer.lineBreakMode = .byTruncatingTail

Handy tip if you want zero height, when, there's no text at all

Often you use a text view to only display text. So, you use lines "0" to mean the text view will automatically change height depending on how many lines of text.

That's great. But if there is no text at all, then unfortunately you get the same height as if there is one line of text!!!! The text view never "goes away".

If you want it to "go away", just add this

override var intrinsicContentSize: CGSize {
    var i = super.intrinsicContentSize
    print("for \(text) size will be \(i)")
    if text == "" { i.height = 1.0 }
    print("   but we changed it to \(i)")
    return i
}

(I made it '1' height so it's clear what's going on in that demo, '0' is fine.)

What about UILabel ?

When just displaying text, UILabel has many advantages over UITextView. UILabel does not suffer from the problems described on this QA page.

Indeed the reason we all usually "give up" and just use UITextView is that UILabel is difficult to work with. In particular it is ridiculously difficult to just add padding, correctly, to UILabel.

In fact here is a full discussion on how to "finally" correctly add padding to UILabel: https://stackoverflow.com/a/58876988/294884 In some cases if you are doing a difficult layout with dynamic height cells, it is sometimes better to do it the hard way with UILabel.

Response.Write is used to display the text not for executing JavaScript, If you want to execute the JavaScript from your code than try as below:

try
{
    con.Open();
    string pass="abc";
    cmd = new SqlCommand("insert into register values('" + txtName.Text + "','" + txtEmail.Text + "','" + txtPhoneNumber.Text + "','" + ddlUserType.SelectedText + "','" + pass + "')", con);
    cmd.ExecuteNonQuery();
    con.Close();
    Page.ClientScript.RegisterStartupScript(this.GetType(), "click","alert('Login Successful');");
}
catch (Exception ex)
{
}
finally
{
    con.Close();
}

If you're referring to what happens when you echo something, the single quotes will literally echo what you have between them, while the double quotes will evaluate variables between them and output the value of the variable.

For example, this

#!/bin/sh
MYVAR=sometext
echo "double quotes gives you $MYVAR"
echo 'single quotes gives you $MYVAR'

will give this:

double quotes gives you sometext
single quotes gives you $MYVAR

I looked at my Environment Variables and had a System Variable called _JAVA_OPTIONS with the value -Xms256m -Xmx512m, after changing this to -Xms256m -Xmx1024m the max heap size increased accordingly.

Have you tried just

dictionary["cat"] = 5;

:)

Update

dictionary["cat"] = 5+2;
dictionary["cat"] = dictionary["cat"]+2;
dictionary["cat"] += 2;

Beware of non-existing keys :)

make sure the name of the folder that contains the font name is "fonts" not "font"

You can use Named Sections.

_Layout.cshtml

<head>
    <script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
    @RenderSection("JavaScript", required: false)
</head>

_SomeView.cshtml

@section JavaScript
{
   <script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
   <script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}

The following line replaces None with NaN:

df['column'].replace('None', np.nan, inplace=True)

The second form (creating an HTTP server yourself, instead of having Express create one for you) is useful if you want to reuse the HTTP server, for example to run socket.io within the same HTTP server instance:

var express = require('express');
var app     = express();
var server  = require('http').createServer(app);
var io      = require('socket.io').listen(server);
...
server.listen(1234);

However, app.listen() also returns the HTTP server instance, so with a bit of rewriting you can achieve something similar without creating an HTTP server yourself:

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

// app.use/routes/etc...

var server    = app.listen(3033);
var io        = require('socket.io').listen(server);

io.sockets.on('connection', function (socket) {
  ...
});

There are two ways(actually there are more) that you could do this.
1. using lxml
pip install lxml

from lxml import etree, objectify
from lxml.etree import XMLSyntaxError

def xml_validator(some_xml_string, xsd_file='/path/to/my_schema_file.xsd'):
    try:
        schema = etree.XMLSchema(file=xsd_file)
        parser = objectify.makeparser(schema=schema)
        objectify.fromstring(some_xml_string, parser)
        print "YEAH!, my xml file has validated"
    except XMLSyntaxError:
        #handle exception here
        print "Oh NO!, my xml file does not validate"
        pass

xml_file = open('my_xml_file.xml', 'r')
xml_string = xml_file.read()
xml_file.close()

xml_validator(xml_string, '/path/to/my_schema_file.xsd')

2. Use xmllint from the commandline. xmllint comes installed in many linux distributions.

>> xmllint --format --pretty 1 --load-trace --debug --schema /path/to/my_schema_file.xsd /path/to/my_xml_file.xml

I had a problem recently, the link was opened in a new tab, but selenium focused still on the initial tab.

I'm using Chromedriver and the only way to focus on a tab was for me to use switch_to_window().

Here's the Python code:

driver.switch_to_window(driver.window_handles[-1])

So the tip is to find out the name of the window handle you need, they are stored as list in

driver.window_handles

You might also like numpy:

>>> import numpy as np
>>> np.ceil(2.3)
3.0

I'm not saying it's better than math, but if you were already using numpy for other purposes, you can keep your code consistent.

Anyway, just a detail I came across. I use numpy a lot and was surprised it didn't get mentioned, but of course the accepted answer works perfectly fine.

By turning them into integers instead:

percent = (int(pyc) / int(tpy)) * 100;

In python 3, the input() function returns a string. Always. This is a change from Python 2; the raw_input() function was renamed to input().

You can use several methods for this issue like

1. Using line-height

   #wrapper {  line-height: 0px;  }
   

2. Using display: flex

   #wrapper {  display: flex;         }
   #wrapper {  display: inline-flex;  }
   

3. Using display: block, table, flex and inherit

   #wrapper img {  display: block;    }
   #wrapper img {  display: table;    }
   #wrapper img {  display: flex;     }
   #wrapper img {  display: inherit;  }
   

Suppose you have two commits in local branch:

      D---E master
     /
A---B---C---F origin/master

After "git pull", will be:

      D--------E  
     /          \
A---B---C---F----G   master, origin/master

After "git pull --rebase", there will be no merge point G. Note that D and E become different commits:

A---B---C---F---D'---E'   master, origin/master

There's nothing wrong with passing integers to str. One reason you might not do this is that myList is really supposed to be a list of integers e.g. it would be reasonable to sum the values in the list. In that case, do not pass your ints to str before appending them to myList. If you end up not converting to strings before appending, you can construct one big string by doing something like

', '.join(map(str, myList))

I found this:

private static string ToLiteral(string input)
{
    using (var writer = new StringWriter())
    {
        using (var provider = CodeDomProvider.CreateProvider("CSharp"))
        {
            provider.GenerateCodeFromExpression(new CodePrimitiveExpression(input), writer, null);
            return writer.ToString();
        }
    }
}

This code:

var input = "\tHello\r\n\tWorld!";
Console.WriteLine(input);
Console.WriteLine(ToLiteral(input));

Produces:

    Hello
    World!
"\tHello\r\n\tWorld!"

Sorry that I can not make a comment to the first answer But you should use new instance to execute the command: cmd_output=$($@)

#!/bin/bash

function check_exit {
    cmd_output=$($@)
    local status=$?
    echo $status
    if [ $status -ne 0 ]; then
        echo "error with $1" >&2
    fi
    return $status
}

function run_command() {
    exit 1
}

check_exit run_command

I had a similar problem, but in my case I was missing the google-services plugin from my Gradle build (I was adding Firebase to an existing project).

I added the following to my root build.gradle:

classpath 'com.google.gms:google-services:3.1.0'

and the following to the end of my app-level build.gradle:

apply plugin: 'com.google.gms.google-services'

I then had to download the google-services.json file from the Firebase Console (having originally imported an existing Google Cloud project) and copy it to my app directory`.

try this :

public class FileStore
 {
   [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
   public Guid Id { get; set; }
   public string Name { get; set; }
   public string Path { get; set; }
 }

You can check this SO post.

Correct way to check for null or empty or string containing only spaces is like this:

if(str != null && !str.trim().isEmpty()) { /* do your stuffs here */ }

If you have the Apache common utilities in your project rather use the first one. Because its shorter and does exactly the same as the latter one. There won't be any difference between both methods but how it looks inside the source code.

Also a empty check using

listName.size() != 0

Is discouraged because all collection implementations have the

listName.isEmpty()

function that does exactly the same.

So all in all, if you have the Apache common utils in your classpath anyway, use

if (CollectionUtils.isNotEmpty(listName)) 

in any other case use

if(listName != null && listName.isEmpty())

You will not notice any performance difference. Both lines do exactly the same.

For that you just need write to some lines

   DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
   ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
   drawer.addDrawerListener(toggle);
   toggle.setDrawerIndicatorEnabled(true);

The <a>nchor element is simply an anchor to or from some content. Originally the HTML specification allowed for named anchors (<a name="foo">) and linked anchors (<a href="#foo">).

The named anchor format is less commonly used, as the fragment identifier is now used to specify an [id] attribute (although for backwards compatibility you can still specify [name] attributes). An <a> element without an [href] attribute is still valid.

As far as semantics and styling is concerned, the <a> element isn't a link (:link) unless it has an [href] attribute. A side-effect of this is that an <a> element without [href] won't be in the tabbing order by default.

The real question is whether the <a> element alone is an appropriate representation of a <button>. On a semantic level, there is a distinct difference between a link and a button.

A button is something that when clicked causes an action to occur.

A link is a button that causes a change in navigation in the current document. The navigation that occurs could be moving within the document in the case of fragment identifiers (#foo) or moving to a new document in the case of urls (/bar).

As links are a special type of button, they have often had their actions overridden to perform alternative functions. Continuing to use an anchor as a button is ok from a consistency standpoint, although it's not quite accurate semantically.

If you're concerned about the semantics and accessibility of using an <a> element (or <span>, or <div>) as a button, you should add the following attributes:

<a role="button" tabindex="0" ...>...</a>

The button role tells the user that the particular element is being treated as a button as an override for whatever semantics the underlying element may have had.

For <span> and <div> elements, you may want to add JavaScript key listeners for Space or Enter to trigger the click event. <a href> and <button> elements do this by default, but non-button elements do not. Sometimes it makes more sense to bind the click trigger to a different key. For example, a "help" button in a web app might be bound to F1.

UTF-8 is prepared for world domination, Latin1 isn't.

If you're trying to store non-Latin characters like Chinese, Japanese, Hebrew, Russian, etc using Latin1 encoding, then they will end up as mojibake. You may find the introductory text of this article useful (and even more if you know a bit Java).

Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full 4-byte UTF-8 support, upgrade MySQL to at least 5.5 or go for another RDBMS like PostgreSQL. In MySQL 5.5+ it's called utf8mb4.

Following code will solve json response if there Basic Authentication and Proxy implemented.Also IIS 7.5 Hosting Problm will resolve.

public string HttpGetByWebRequ(string uri, string username, string password)
{
//For Basic Authentication
    string authInfo = username + ":" + password;
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));

//For Proxy
    WebProxy proxy = new WebProxy("http://10.127.0.1:8080", true);

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    request.Method = "GET";
    request.Accept = "application/json; charset=utf-8";
    request.Proxy = proxy;

    request.Headers["Authorization"] = "Basic " + authInfo;

    var response = (HttpWebResponse)request.GetResponse();

    string strResponse = "";
    using (var sr = new StreamReader(response.GetResponseStream()))
    {
        strResponse= sr.ReadToEnd();

    }

    return strResponse;
}

If you're using Qt Jambi, this should work:

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

This Depends on what version of python is installed on you system. See below.

If You have Python 2.* version you have to run this command

python gameover.py

But if you have Python 3.* version you have to run this command

python3 gameover.py

Because for MAC with Python version 3.* you will get command not found error

if you run "python gameover.py"

in Firefox 39 I've found that setting a border to the select element will render the arrow as (2). No border set, will render the arrow as (1). I think it's a bug.

You don't need to list ContactPhoneAreaCode1 and ContactPhoneNumber1

SELECT FirstName AS First_Name, 
LastName AS Last_Name, 
COALESCE(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
FROM TABLE1

public static void main(String[] args) {
    double g = 1 / 3;
    System.out.printf("%.2f", g);
}

Since both 1 and 3 are ints the result not rounded but it's truncated. So you ignore fractions and take only wholes.

To avoid this have at least one of your numbers 1 or 3 as a decimal form 1.0 and/or 3.0.

With Spring 4 you only add @EnableWebMvc, for example:

@Controller
@EnableWebMvc
@RequestMapping(value = "/articles/action", headers="Accept=*/*",  produces="application/json")
public class ArticlesController {

}

Or even shorter, with only standard modern Javascript:

var first_link = document.getElementsByTagName('a')[0];
first_link.dispatchEvent(new MouseEvent('click'));

The new MouseEvent constructor takes a required event type name, then an optional object (at least in Chrome). So you could, for example, set some properties of the event:

first_link.dispatchEvent(new MouseEvent('click', {bubbles: true, cancelable: true}));

As noted in the comments, the query in Saharsh Shah's answer must be run multiple times if items are duplicated more than once.

Here's a solution that doesn't delete any data, and keeps the data in the original table the entire time, allowing for duplicates to be deleted while keeping the table 'live':

alter table tableA add column duplicate tinyint(1) not null default '0';

update tableA set
duplicate=if(@member_id=member_id
             and @quiz_num=quiz_num
             and @question_num=question_num
             and @answer_num=answer_num,1,0),
member_id=(@member_id:=member_id),
quiz_num=(@quiz_num:=quiz_num),
question_num=(@question_num:=question_num),
answer_num=(@answer_num:=answer_num)
order by member_id, quiz_num, question_num, answer_num;

delete from tableA where duplicate=1;

alter table tableA drop column duplicate;

This basically checks to see if the current row is the same as the last row, and if it is, marks it as duplicate (the order statement ensures that duplicates will show up next to each other). Then you delete the duplicate records. I remove the duplicate column at the end to bring it back to its original state.

It looks like alter table ignore also might go away soon: http://dev.mysql.com/worklog/task/?id=7395

Alternatively, you could do:

for i in range(0, len(a), 2):
    #do something

The extended slice notation is much more concise, though.

Since itunesconnect has been changed i am updating with the new steps here.

You have to follow through these steps

1. Login to itunesconnect
2. Choose your app in My Apps section
3. Under Appstore tab choose "Pricing and Availability"
4. Under Availability section click edit will open a popup listing the territories
5. Uncheck all the territories and click Done

var a = "acvbasbb";
var b= {};
for (let i=0;i<a.length;i++){
    if((a.match(new RegExp(a[i], "g"))).length > 1){
        b[a[i]]=(a.match(new RegExp(a[i], "g"))).length;
    }
}
console.log(b);

In javascript you can use above code to get occurrence of a character in a string.

simply change <div> to <tbody>

<table id="authenticationSetting" style="display: none">
  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>
      <td class="orionSummaryColumn">
        <orion:textbox id="authenticationOuterIdentity" size="30" />
      </td>
    </tr>
  </tbody>
</table>

This is what ended up working.

$("select").change(function(){
    $.get("/page.html?" + $(this).parent("form").find(":input").serialize()); 
});

If you are on Rails 4 and you get this error, it could happen if you are using enum on the model if you've defined with symbols like this:

class User
  enum preferred_phone: [:home_phone, :mobile_phone, :work_phone]
end

The form will pass say a radio selector as a string param. That's what happened in my case. The simple fix is to change enum to strings instead of symbols

enum preferred_phone: %w[home_phone mobile_phone work_phone]
# or more verbose
enum preferred_phone: ['home_phone', 'mobile_phone', 'work_phone']

double f_round(double dval, int n)
{
    char l_fmtp[32], l_buf[64];
    char *p_str;
    sprintf (l_fmtp, "%%.%df", n);
    if (dval>=0)
            sprintf (l_buf, l_fmtp, dval);
    else
            sprintf (l_buf, l_fmtp, dval);
    return ((double)strtod(l_buf, &p_str));

}

Here n is the number of decimals

example:

double d = 100.23456;

printf("%f", f_round(d, 4));// result: 100.2346

printf("%f", f_round(d, 2));// result: 100.23

Or you can just make an ICollection extension like this:

 public static ICollection<T> AddRange<T>(this ICollection<T> @this, IEnumerable<T> items)
    {
        foreach(var item in items)
        {
            @this.Add(item);
        }

        return @this;
    }

Using it would be just like using it on a list:

collectionA.AddRange(IEnumerable<object> items);

Though I consider myself a .NET developer, I don't prefer calling it that way. c# developer sounds much better and is a much clearer message: it says that I understand both C# and .NET (because C# and .NET are tied together). I could call myself a VB.NET developer, same story there.

What is a .NET developer? I don't know, because you cannot develop with .NET, if develop is a synonym for programming. .NET is the environment, the libraries, the languages, the CLR, the CLI, JIT, the LR, the BCL, the IDE and the IL. I find it a poor job description, but it may also mean that they don't really care: either you are an F#, a C#, an IronPython or a VB.NET developer, they're all implicitly and secretly .NET developers.

What do you need? A solid understanding why ".NET" is a poor job description and ask for a more precise one. Nobody can know everything of .NET, it is simply too wide. Orientate yourself to all sides of it and do both ASP.NET and WinForms. Don't forget Silverlight, WPF etc and two or three .NET languages.

In other words: know the forest by knowing what trees and flowers it habitats and specialize in knowing a few beautiful and common ones well.

It seems that in the debug log for Java 6 the request is send in SSLv2 format.

main, WRITE: SSLv2 client hello message, length = 110

This is not mentioned as enabled by default in Java 7.
Change the client to use SSLv3 and above to avoid such interoperability issues.

Look for differences in JSSE providers in Java 7 and Java 6

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

Even though this question is answered, providing an example as to what "theirs" and "ours" means in the case of git rebase vs merge. See this link

Git Rebase
theirs is actually the current branch in the case of rebase. So the below set of commands are actually accepting your current branch changes over the remote branch.

# see current branch
$ git branch
... 
* branch-a
# rebase preferring current branch changes during conflicts
$ git rebase -X theirs branch-b

Git Merge
For merge, the meaning of theirs and ours is reversed. So, to get the same effect during a merge, i.e., keep your current branch changes (ours) over the remote branch being merged (theirs).

# assuming branch-a is our current version
$ git merge -X ours branch-b  # <- ours: branch-a, theirs: branch-b

Yes, I believe you are creating thousands of objects. If you're looking for an easy way to delete a bunch of them at once, use canvas tags described here. This lets you perform the same operation (such as deletion) on a large number of objects.

If you're using gcc and want to disable the warning for selected code, you can use the #pragma compiler directive:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-variable"

#pragma GCC diagnostic pop

For code you control, you may also use __attribute__((unused)) to instruct the compiler that specific variables are not used.

Add a string at the end of your URL to break the cache. I usually do (with PHP):

<script src="/my/js/file.js?<?=time()?>"></script>

So that it reloads every time while I'm working on it, and then take it off when it goes into production. In reality I abstract this out a little more but the idea remains the same.

If you check out the source of this website, they append the revision number at the end of the URL in a similar fashion to force the changes upon us whenever they update the javascript files.

If key is present table.put(key, val) will just overwrite the value else it'll create a new entry. Poof! and you are done. :)

you can get the value from a map by using key is table.get(key); That's about it

The Difference

There are a few characters which can indicate a new line. The usual ones are these two:

* '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF).
* '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

* DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

* Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

* Mac

Macs use a single '\r'.

Taken from Here

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

InnerHTML should be innerHTML:

document.getElementById('LblAboutMeCount').innerHTML = charsleft;

You should bind your checkLength function to your textarea with jQuery rather than calling it inline and rather intrusively:

$(document).ready(function() {
    $('textarea[name=text]').keypress(function(e) {
        checkLength($(this),512,$('#LblTextCount'));
    }).focus(function() {
        checkLength($(this),512,$('#LblTextCount'));
    });
});

You can neaten up checkLength by using more jQuery, and I wouldn't use 'object' as a formal parameter:

function checkLength(obj, maxlength, label) {
    charsleft = (maxlength - obj.val().length);
    // never allow to exceed the specified limit
    if( charsleft < 0 ) {
        obj.val(obj.val().substring(0, maxlength-1));
    }
    // I'm trying to set the value of charsleft into the label
    label.text(charsleft);
    $('#LblAboutMeCount').html(charsleft);
}

So if you apply the above, you can change your markup to:

<textarea name="text"></textarea>

For Python 3.5+:

So, you can get the stacktrace from your exception as from any other exception. Use traceback.TracebackException for it (just replace ex with your exception):

print("".join(traceback.TracebackException.from_exception(ex).format())

An extended example and other features to do this:

import traceback

try:
    1/0
except Exception as ex:
    print("".join(traceback.TracebackException.from_exception(ex).format()) == traceback.format_exc() == "".join(traceback.format_exception(type(ex), ex, ex.__traceback__))) # This is True !!
    print("".join(traceback.TracebackException.from_exception(ex).format()))

The output will be something like this:

True
Traceback (most recent call last):
  File "untidsfsdfsdftled.py", line 29, in <module>
    1/0
ZeroDivisionError: division by zero

A lot of the answers here are great. But I wanted something a little simpler. I wanted something that will work with the "Hello World" sample for free. This means I wanted a simple produces a request body that matches the query string:

{
#foreach($param in $input.params().querystring.keySet())
  "$param": "$util.escapeJavaScript($input.params().querystring.get($param))" #if($foreach.hasNext),#end
#end
}

I think the top answer produces something more useful when building something real, but for getting a quick hello world running using the template from AWS this works great.

The fix

Go to Project Structure - Modules - Source Folders and find the target/generated-sources/antlr4/com/mycompany - click Edit properties and set Package prefix to com.mycompany.

Different but related problem here

And remember to use parenthesis!

Keep in mind that & operator takes a precedence over operators such as > or < etc. That is why

4 < 5 & 6 > 4

evaluates to False. Therefore if you're using pd.loc, you need to put brackets around your logical statements, otherwise you get an error. That's why do:

df.loc[(df['A'] > 10) & (df['B'] < 15)]

instead of

df.loc[df['A'] > 10 & df['B'] < 15]

which would result in

TypeError: cannot compare a dtyped [float64] array with a scalar of type [bool]

I think that biases are almost always helpful. In effect, a bias value allows you to shift the activation function to the left or right, which may be critical for successful learning.

It might help to look at a simple example. Consider this 1-input, 1-output network that has no bias:

The output of the network is computed by multiplying the input (x) by the weight (w₀) and passing the result through some kind of activation function (e.g. a sigmoid function.)

Here is the function that this network computes, for various values of w₀:

Changing the weight w₀ essentially changes the "steepness" of the sigmoid. That's useful, but what if you wanted the network to output 0 when x is 2? Just changing the steepness of the sigmoid won't really work -- you want to be able to shift the entire curve to the right.

That's exactly what the bias allows you to do. If we add a bias to that network, like so:

...then the output of the network becomes sig(w₀*x + w₁*1.0). Here is what the output of the network looks like for various values of w₁:

Having a weight of -5 for w₁ shifts the curve to the right, which allows us to have a network that outputs 0 when x is 2.

If u want to use display=block it will make the content reader jump, so instead of using display you can set the left attribute to a negative value which does not exist in your html page to be displayed but actually it do.

    String getSimSerialNumber = telemamanger.getSimSerialNumber();

The solution is running this command:

set OPENSSL_CONF=C:\OpenSSL-Win32\bin\openssl.cfg   

or

set OPENSSL_CONF=[path-to-OpenSSL-install-dir]\bin\openssl.cfg

in the command prompt before using openssl command.

Let openssl know for sure where to find its .cfg file.

Alternatively you could set the same variable OPENSSL_CONF in the Windows environment variables.

NOTE: This can happen when using the OpenSSL binary distribution from Shining Light Productions (a compiled + installer version of the official OpenSSL that is free to download & use). This distribution is "semi-officially" linked from OpenSSL's site as a "service primarily for operating systems where there are no pre-compiled OpenSSL packages".

Majority of the solutions above have a high run time complexity.

Here is the solution that uses reduce and can do the job in O(n) time.

Array.prototype.unique = Array.prototype.unique || function() {_x000D_
        var arr = [];_x000D_
 this.reduce(function (hash, num) {_x000D_
  if(typeof hash[num] === 'undefined') {_x000D_
   hash[num] = 1; _x000D_
   arr.push(num);_x000D_
  }_x000D_
  return hash;_x000D_
 }, {});_x000D_
 return arr;_x000D_
}_x000D_
    _x000D_
var myArr = [3,1,2,3,3,3];_x000D_
console.log(myArr.unique()); //[3,1,2];

Note:

This solution is not dependent on reduce. The idea is to create an object map and push unique ones into the array.

From GIT documentation: Git Docs

Below gives the full information. In short, simple will only push the current working branch and even then only if it also has the same name on the remote. This is a very good setting for beginners and will become the default in GIT 2.0

Whereas matching will push all branches locally that have the same name on the remote. (Without regard to your current working branch ). This means potentially many different branches will be pushed, including those that you might not even want to share.

In my personal usage, I generally use a different option: current which pushes the current working branch, (because I always branch for any changes). But for a beginner I'd suggest simple

push.default
Defines the action git push should take if no refspec is explicitly given. Different values are well-suited for specific workflows; for instance, in a purely central workflow (i.e. the fetch source is equal to the push destination), upstream is probably what you want. Possible values are:

nothing - do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.

current - push the current branch to update a branch with the same name on the receiving end. Works in both central and non-central workflows.

upstream - push the current branch back to the branch whose changes are usually integrated into the current branch (which is called @{upstream}). This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow).

simple - in centralized workflow, work like upstream with an added safety to refuse to push if the upstream branch's name is different from the local one.

When pushing to a remote that is different from the remote you normally pull from, work as current. This is the safest option and is suited for beginners.

This mode will become the default in Git 2.0.

matching - push all branches having the same name on both ends. This makes the repository you are pushing to remember the set of branches that will be pushed out (e.g. if you always push maint and master there and no other branches, the repository you push to will have these two branches, and your local maint and master will be pushed there).

To use this mode effectively, you have to make sure all the branches you would push out are ready to be pushed out before running git push, as the whole point of this mode is to allow you to push all of the branches in one go. If you usually finish work on only one branch and push out the result, while other branches are unfinished, this mode is not for you. Also this mode is not suitable for pushing into a shared central repository, as other people may add new branches there, or update the tip of existing branches outside your control.

This is currently the default, but Git 2.0 will change the default to simple.

I'm late but I need to say for those who need an object, using only html, there's a way. In some server side frameworks like PHP you can write the follow code:

<form action="myurl" method="POST" name="myForm">
        <p><label for="first_name">First Name:</label>
        <input type="text" name="name[first]" id="fname"></p>

        <p><label for="last_name">Last Name:</label>
        <input type="text" name="name[last]" id="lname"></p>

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

So, we need setup the name of the input as object[property] for got an object. In the above example, we got a data with the follow JSON:

{
"name": {
  "first": "some data",
  "last": "some data"
 }
}

I didn't read if my solution is already posted but on linux and osx you can read the 0 argument in your main function like this:

int main(int argument_count, char **argument_list) {
    std::string currentWorkingDirectoryPath(argument_list[currentWorkingDirectory]);
    std::size_t pos = currentWorkingDirectoryPath.rfind("/");      // position of "live" in str
    currentWorkingDirectoryPath = currentWorkingDirectoryPath.substr (0, pos);

In the first item of argument_list the name of the executable is integrated but removed by the code above.

Use simple command:

keytool -exportcert -keystore path-to-debug-or-production-keystore -list -v

and you will get the SHA1 key.

According to https://www.mongodb.com/blog/post/6-rules-of-thumb-for-mongodb-schema-design-part-1

If you expect that a blog post may exceed the 16Mb document limit, you should extract the comments into a separate collection and reference the blog post from the comment and do an application-level join.

// posts
[
  {
    _id: ObjectID('AAAA'),
    text: 'a post',
    ...
  }
]

// comments
[
  {
    text: 'a comment'
    post: ObjectID('AAAA')
  },
  {
    text: 'another comment'
    post: ObjectID('AAAA')
  }
]

This is not actually adding the CSS to the cell, but gives the same effect. While providing the same result as others above, this version is a little more intuitive to me, but I'm a novice, so take it for what it's worth:

$(".hoverCell").bind('mouseover', function() {
    var old_color = $(this).css("background-color");
    $(this)[0].style.backgroundColor = '#ffff00';

    $(".hoverCell").bind('mouseout', function () {
        $(this)[0].style.backgroundColor = old_color;
    });
});

This requires setting the Class for each of the cells you want to highlight to "hoverCell".

What you describe is the default behavior. You have to detect and handle these events yourself by adding:

android:configChanges

to your manifest and then the changes that you want to handle. So for orientation, you would use:

android:configChanges="orientation"

and for the keyboard being opened or closed you would use:

android:configChanges="keyboardHidden"

If you want to handle both you can just separate them with the pipe command like:

android:configChanges="keyboardHidden|orientation"

This will trigger the onConfigurationChanged method in whatever Activity you call. If you override the method you can pass in the new values.

Hope this helps.

This is the only solution that would work for me, when I required a space in between the columns being merged.

select concat(concat(column1,' '), column2)

if ($("#cartContent").children().length == 0) 
{
     // no child
}

In summary, it's to improve code readability, reduce chances of errors by reusing rather than replicating code, and leverage optimization happening behind the scenes.

Try this. Here is the code to get the sheet names in order.

private Dictionary<int, string> GetExcelSheetNames(string fileName)
{
    Excel.Application _excel = null;
    Excel.Workbook _workBook = null;
    Dictionary<int, string> excelSheets = new Dictionary<int, string>();
    try
    {
        object missing = Type.Missing;
        object readOnly = true;
        Excel.XlFileFormat.xlWorkbookNormal
        _excel = new Excel.ApplicationClass();
        _excel.Visible = false;
        _workBook = _excel.Workbooks.Open(fileName, 0, readOnly, 5, missing,
            missing, true, Excel.XlPlatform.xlWindows, "\\t", false, false, 0, true, true, missing);
        if (_workBook != null)
        {
            int index = 0;
            foreach (Excel.Worksheet sheet in _workBook.Sheets)
            {
                // Can get sheet names in order they are in workbook
                excelSheets.Add(++index, sheet.Name);
            }
        }
    }
    catch (Exception e)
    {
        return null;
    }
    finally
    {
        if (_excel != null)
        {

            if (_workBook != null)
                _workBook.Close(false, Type.Missing, Type.Missing);
            _excel.Application.Quit();
        }
        _excel = null;
        _workBook = null;

getCurrentScript and getCurrentScriptPath

I came up with the following:

//Thanks to https://stackoverflow.com/a/27369985/5175935
var getCurrentScript = function () {

    if ( document.currentScript && ( document.currentScript.src !== '' ) )
        return document.currentScript.src;
    var scripts = document.getElementsByTagName( 'script' ),
        str = scripts[scripts.length - 1].src;
    if ( str !== '' )
        return src;
    //Thanks to https://stackoverflow.com/a/42594856/5175935
    return new Error().stack.match(/(https?:[^:]*)/)[0];

};

//Thanks to https://stackoverflow.com/a/27369985/5175935
var getCurrentScriptPath = function () {
    var script = getCurrentScript(),
        path = script.substring( 0, script.lastIndexOf( '/' ) );
    return path;
};

I had the same problem. What I did was:

sudo apt-get update

And then reinstall ruby-full

sudo apt-get install ruby-full

Anyone facing this while using cmake build, the solution is to make sure you have included the four supported platforms in your app module's android{} block:

 externalNativeBuild {
            cmake {

                abiFilters "arm64-v8a", "x86", "armeabi-v7a", "x86_64"
            }
        }

WhatsApp has chosen Erlang a language built for writing scalable applications that are designed to withstand errors. Erlang uses an abstraction called the Actor model for it's concurrency - http://en.wikipedia.org/wiki/Actor_(programming_language) Instead of the more traditional shared memory approach, actors communicate by sending each other messages. Actors unlike threads are designed to be lightweight. Actors could be on the same machine or on different machines and the message passing abstractions works for both. A simple implementation of WhatsApp could be: Each user/device is represented as an actor. This actor is responsible for handling the inbox of the user, how it gets serialized to disk, the messages that the user sends and the messages that the user receives. Let's assume that Alice and Bob are friends on WhatsApp. So there is an an Alice actor and a Bob actor.

Let's trace a series of messages flowing back and forth:

Alice decides to message Bob. Alice's phone establishes a connection to the WhatsApp server and it is established that this connection is definitely from Alice's phone. Alice now sends via TCP the following message: "For Bob: A giant monster is attacking the Golden Gate Bridge". One of the WhatsApp front end server deserializes this message and delivers this message to the actor called Alice.

Alice the actor decides to serialize this and store it in a file called "Alice's Sent Messages", stored on a replicated file system to prevent data loss due to unpredictable monster rampage. Alice the actor then decides to forward this message to Bob the actor by passing it a message "Msg1 from Alice: A giant monster is attacking the Golden Gate Bridge". Alice the actor can retry with exponential back-off till Bob the actor acknowledges receiving the message.

Bob the actor eventually receives the message from (2) and decides to store this message in a file called "Bob's Inbox". Once it has stored this message durably Bob the actor will acknowledge receiving the message by sending Alice the actor a message of it's own saying "I received Msg1". Alice the actor can now stop it's retry efforts. Bob the actor then checks to see if Bob's phone has an active connection to the server. It does and so Bob the actor streams this message to the device via TCP.

Bob sees this message and replies with "For Alice: Let's create giant robots to fight them". This is now received by Bob the actor as outlined in Step 1. Bob the actor then repeats Step 2 and 3 to make sure Alice eventually receives the idea that will save mankind.

WhatsApp actually uses the XMPP protocol instead of the vastly superior protocol that I outlined above, but you get the point.

You can use this:

  <Button
                    android:id="@+id/reset_all"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginRight="5dp"
                    android:layout_weight="1"
                    android:background="@drawable/btn_med"
                    android:text="Reset all"
                    android:textColor="#ffffff" />

                <Button
                    android:id="@+id/undo"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="5dp"
                    android:layout_weight="1"
                    android:background="@drawable/btn_med"
                    android:text="Undo"
                    android:textColor="#ffffff" />

in that i have put an image as background and also added text..!

In my case I got this error when trying to impersonate as another user. E.g.

EXEC AS USER = 'dbo';

And as the database was imported from another environment, some of its users did not match the SQL Server logins.

You can check if you have the same problem by running the (deprecated) sp_change_users_login (in "Report" mode), or use the following query:

select p.name,p.sid "sid in DB", (select serp.sid from sys.server_principals serp where serp.name = p.name) "sid in server"
from sys.database_principals p
where p.type in ('G','S','U')
and p.authentication_type = 1
and p.sid not in (select sid from sys.server_principals)

If in that list shows the user you are trying to impersonate, then you probably can fix it by assigning the DB user to the proper login in your server. For instance:

ALTER USER dbo WITH LOGIN = dbo;

You pass the expression you want to group by rather than the alias

SELECT       LastName + ', ' + FirstName AS 'FullName'
FROM         customers
GROUP BY      LastName + ', ' + FirstName

list.ToArray()

Will do the tric. See here for details.

This does the trick:

CC        := g++
LD        := g++

MODULES   := widgets test ui
SRC_DIR   := $(addprefix src/,$(MODULES))
BUILD_DIR := $(addprefix build/,$(MODULES))

SRC       := $(foreach sdir,$(SRC_DIR),$(wildcard $(sdir)/*.cpp))
OBJ       := $(patsubst src/%.cpp,build/%.o,$(SRC))
INCLUDES  := $(addprefix -I,$(SRC_DIR))

vpath %.cpp $(SRC_DIR)

define make-goal
$1/%.o: %.cpp
    $(CC) $(INCLUDES) -c $$< -o $$@
endef

.PHONY: all checkdirs clean

all: checkdirs build/test.exe

build/test.exe: $(OBJ)
    $(LD) $^ -o $@


checkdirs: $(BUILD_DIR)

$(BUILD_DIR):
    @mkdir -p $@

clean:
    @rm -rf $(BUILD_DIR)

$(foreach bdir,$(BUILD_DIR),$(eval $(call make-goal,$(bdir))))

This Makefile assumes you have your include files in the source directories. Also it checks if the build directories exist, and creates them if they do not exist.

The last line is the most important. It creates the implicit rules for each build using the function make-goal, and it is not necessary write them one by one

You can also add automatic dependency generation, using Tromey's way

The other option in this particular case would be to type the degree symbol: °

R seems to handle it fine. Type Option-k on a Mac to get it. Not sure about other platforms.

You can have the @Transactional in the child class, but you have to override each of the methods and call the super method in order to get it to work.

Example:

@Transactional(readOnly = true)
public class Bob<SomeClass> {
   @Override
   public SomeClass getValue() {
       return super.getValue();
   }
}

This allows it to set it up for each of the methods it's needed for.

Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.

Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.

In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

If you don't want to depend on @@DATEFIRST or use DATEPART(weekday, DateColumn), just calculate the day of the week yourself.

For Monday based weeks (Europe) simplest is:

SELECT DATEDIFF(day, '17530101', DateColumn) % 7 + 1 AS MondayBasedDay

For Sunday based weeks (America) use:

SELECT DATEDIFF(day, '17530107', DateColumn) % 7 + 1 AS SundayBasedDay

This return the weekday number (1 to 7) ever since January 1st respectively 7th, 1753.

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

Happy coding :-)

For a more detailed explanation, check out this post:

http://www.viget.com/inspire/webkit-transform-kill-the-flash/

I would definitely avoid applying it to the entire body. The key is to make sure whatever specific element you plan on transforming in the future starts out rendered in 3d so the browsers doesn't have to switch in and out of rendering modes. Adding

-webkit-transform: translateZ(0) 

(or either of the options already mentioned) to the animated element will accomplish this.

This line:

private dynamic defaultReminder = 
                          reminder.TimeSpanText[TimeSpan.FromMinutes(15)];

You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder will be initialized before defaultReminder, so the above line might throw a NullReferenceException.

Instead, just use:

private dynamic defaultReminder = TimeSpan.FromMinutes(15);

Alternatively, set up the value in the constructor:

private dynamic defaultReminder;

public Reminders()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 
}

Running ASP.NET Core 2.1 behind a Traefik reverse Proxy on Ubuntu, I need to set its gateway IP in KnownProxies after installing the official Microsoft.AspNetCore.HttpOverrides package

        var forwardedOptions = new ForwardedHeadersOptions {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor,
        };
        forwardedOptions.KnownProxies.Add(IPAddress.Parse("192.168.3.1"));
        app.UseForwardedHeaders(forwardedOptions);

According to the documentation, this is required if the reverse proxy is not running on localhost. The docker-compose.yml of Traefik has assigned a static IP address:

networks:
  my-docker-network:
    ipv4_address: 192.168.3.2

Alternatively, it should be enough to make sure a known network is defined here to specify its gateway in .NET Core.

It looks like you are trying to start the Python interpreter by running the command python.

However the interpreter is already started. It is interpreting python as a name of a variable, and that name is not defined.

Try this instead and you should hopefully see that your Python installation is working as expected:

print("Hello world!")

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

Use getRGB(), it helps ( no complicated programs )

Returns an array of integer pixels in the default RGB color model (TYPE_INT_ARGB) and default sRGB color space, from a portion of the image data.

Since your issue is mostly stylistic (not wanting to fill up the constructor with a bunch of declarations) it can be solved stylistically as well.

The way I view it, many class based languages have the constructor be a function named after the class name itself. Stylistically we could use that that to make an ES6 class that stylistically still makes sense but does not group the typical actions taking place in the constructor with all the property declarations we're doing. We simply use the actual JS constructor as the "declaration area", then make a class named function that we otherwise treat as the "other constructor stuff" area, calling it at the end of the true constructor.

"use strict";

class MyClass
{
    // only declare your properties and then call this.ClassName(); from here
    constructor(){
        this.prop1 = 'blah 1';
        this.prop2 = 'blah 2';
        this.prop3 = 'blah 3';
        this.MyClass();
    }

    // all sorts of other "constructor" stuff, no longer jumbled with declarations
    MyClass() {
        doWhatever();
    }
}

Both will be called as the new instance is constructed.

Sorta like having 2 constructors where you separate out the declarations and the other constructor actions you want to take, and stylistically makes it not too hard to understand that's what is going on too.

I find it's a nice style to use when dealing with a lot of declarations and/or a lot of actions needing to happen on instantiation and wanting to keep the two ideas distinct from each other.

NOTE: I very purposefully do not use the typical idiomatic ideas of "initializing" (like an init() or initialize() method) because those are often used differently. There is a sort of presumed difference between the idea of constructing and initializing. Working with constructors people know that they're called automatically as part of instantiation. Seeing an init method many people are going to assume without a second glance that they need to be doing something along the form of var mc = MyClass(); mc.init();, because that's how you typically initialize. I'm not trying to add an initialization process for the user of the class, I'm trying to add to the construction process of the class itself.

While some people may do a double-take for a moment, that's actually the bit of the point: it communicates to them that the intent is part of construction, even if that makes them do a bit of a double take and go "that's not how ES6 constructors work" and take a second looking at the actual constructor to go "oh, they call it at the bottom, I see", that's far better than NOT communicating that intent (or incorrectly communicating it) and probably getting a lot of people using it wrong, trying to initialize it from the outside and junk. That's very much intentional to the pattern I suggest.

For those that don't want to follow that pattern, the exact opposite can work too. Farm the declarations out to another function at the beginning. Maybe name it "properties" or "publicProperties" or something. Then put the rest of the stuff in the normal constructor.

"use strict";

class MyClass
{
    properties() {
        this.prop1 = 'blah 1';
        this.prop2 = 'blah 2';
        this.prop3 = 'blah 3';
    }

    constructor() {
        this.properties();
        doWhatever();
    }
}

Note that this second method may look cleaner but it also has an inherent problem where properties gets overridden as one class using this method extends another. You'd have to give more unique names to properties to avoid that. My first method does not have this problem because its fake half of the constructor is uniquely named after the class.

Looks like javax.faces.SEPARATOR_CHAR must not be equal to _

ssh-add -D  # Delete all identities.
ssh-add ~/.ssh/your_key

Edit 1
Since I get so many votes, I discovered some issue with this approach and that is that it will remove all your identities so you might have the same issue when you try to read from other repositories and you will need to to this step again for each project...but it might also not be the case for your project

The :javascript filter was removed in version 7.0

The docs says you should use a script tag now, followed by a . char and no preceding space.

Example:

script.
  if (usingJade)
    console.log('you are awesome')
  else
    console.log('use jade')

will be compiled to

<script>
  if (usingJade)
    console.log('you are awesome')
  else
    console.log('use jade')
</script>

The self name is used as the instance reference in class instances. It is only used in class method definitions. Don't use it in functions.

You also cannot reference local variables from other functions or methods with it. You can only reference instance or class attributes using it.

Use a long datatype.

Add on top page

protected void Page_Load(object sender, EventArgs e)
{    
    if (!Page.IsPostBack)
    {
        //Code display data
    }
}

You don't need to use echo or grep. You could do this:

ping -oc 100000 8.8.8.8 > /dev/null && say "up" || say "down"

This is a new tool: oxygene which you can use to build apps for iOS/Mac, Windows RT/8 or Android. It uses a specific language derived from Object Pascal and Visual Studio (and uses .net or java.). It seem to be really powerful, but is not free.

After making no changes to a production server we began receiving this error. After trying several different things and thinking that perhaps there were DNS issues, restarting IIS fixed the issue (restarting only the site did not fix the issue). It likely won't work for everyone but if we tried that first it would have saved a lot of time.

I think you may want to introduce some helper functions to build your button as well as a Stateful widget along with some property to key off of.

• Use a StatefulWidget/State and create a variable to hold your condition (e.g. isButtonDisabled)
• Set this to true initially (if that's what you desire)
• When rendering the button, don't directly set the onPressed value to either null or some function onPressed: () {}
• Instead, conditionally set it using a ternary or a helper function (example below)
• Check the isButtonDisabled as part of this conditional and return either null or some function.
• When the button is pressed (or whenever you want to disable the button) use setState(() => isButtonDisabled = true) to flip the conditional variable.
• Flutter will call the build() method again with the new state and the button will be rendered with a null press handler and be disabled.

Here's is some more context using the Flutter counter project.

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;
  bool _isButtonDisabled;

  @override
  void initState() {
    _isButtonDisabled = false;
  }

  void _incrementCounter() {
    setState(() {
      _isButtonDisabled = true;
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text("The App"),
      ),
      body: new Center(
        child: new Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Text(
              'You have pushed the button this many times:',
            ),
            new Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
            _buildCounterButton(),
          ],
        ),
      ),
    );
  }

  Widget _buildCounterButton() {
    return new RaisedButton(
      child: new Text(
        _isButtonDisabled ? "Hold on..." : "Increment"
      ),
      onPressed: _isButtonDisabled ? null : _incrementCounter,
    );
  }
}

In this example I am using an inline ternary to conditionally set the Text and onPressed, but it may be more appropriate for you to extract this into a function (you can use this same method to change the text of the button as well):

Widget _buildCounterButton() {
    return new RaisedButton(
      child: new Text(
        _isButtonDisabled ? "Hold on..." : "Increment"
      ),
      onPressed: _counterButtonPress(),
    );
  }

  Function _counterButtonPress() {
    if (_isButtonDisabled) {
      return null;
    } else {
      return () {
        // do anything else you may want to here
        _incrementCounter();
      };
    }
  }

You're missing the multiplication operator. Also, you want to do 4/3 in floating point, not integer math.

volume = (4.0 / 3) * Math.PI * Math.pow(radius, 3);

If you want to alter order for columns in Sql server, There is no direct way to do this in SQL Server currently.

Have a look at http://blog.sqlauthority.com/2008/04/08/sql-server-change-order-of-column-in-database-tables/

You can change order while edit design for table.

To check whether a property exists on a JObject, you can use the square bracket syntax and see whether the result is null or not. If the property exists, a JToken will be always be returned (even if it has the value null in the JSON).

JToken token = jObject["param"];
if (token != null)
{
    // the "param" property exists
}

If you have a JToken in hand and you want to see if it is non-empty, well, that depends on what type of JToken it is and how you define "empty". I usually use an extension method like this:

public static class JsonExtensions
{
    public static bool IsNullOrEmpty(this JToken token)
    {
        return (token == null) ||
               (token.Type == JTokenType.Array && !token.HasValues) ||
               (token.Type == JTokenType.Object && !token.HasValues) ||
               (token.Type == JTokenType.String && token.ToString() == String.Empty) ||
               (token.Type == JTokenType.Null);
    }
}

you can use the below code to bring focus to a div, in this example the page scrolls to the <div id="navigation">

$('html, body').animate({ scrollTop: $('#navigation').offset().top }, 'slow');

In my case, I was having a similar problem:

/usr/bin/ld: Bank.cpp:(.text+0x19c): undefined reference to 'Account::SetBank(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)' collect2: error: ld returned 1 exit status

After some researches, I realized that the problem was being generated by the way that Visual Studio Code was compiling the Bank.cpp file. So, to solve that, I just prompted the follow command in order to compile the c++ file sucessful:

g++ Bank.cpp Account.cpp -o Bank

With the command above, It was able to linkage correctly the Header, Implementations and Main c++ files.

OBS: My g++ version: 9.3.0 on Ubuntu 20.04

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

<div class="control-group">
   <label class="control-label" for="firstname">First Name</label>
   <div class="controls">
    <input type="text" id="firstname" name="firstname"/>
   </div>
</div>

Also we can use it Simply as

<label>First name:
    <input type="text" id="firstname" name="firstname"/>
</label>

How to use index in select statement?
this way:

   SELECT * FROM table1 USE INDEX (col1_index,col2_index)
    WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM table1 IGNORE INDEX (col3_index)
WHERE col1=1 AND col2=2 AND col3=3;

SELECT * FROM t1 USE INDEX (i1) IGNORE INDEX (i2) USE INDEX (i2);

And many more ways check this

Do I need to explicitly specify?

• No, no Need to specify explicitly.
• DB engine should automatically select the index to use based on query execution plans it builds from @Tudor Constantin answer.
• The optimiser will judge if the use of your index will make your query run faster, and if it is, it will use the index. from @niktrl answer

Try this, This was the solution that worked for me:

<div class="modal-dialog" style="min-width: 1500px" role="document">

add these code into the top of your script to solve problem

@set_magic_quotes_runtime(false);
ini_set('magic_quotes_runtime', 0);

Two suggestions:

1. Use std::deque instead of std::vector for better performance in your specific case and use the method std::deque::pop_front().
2. Rethink (I mean: delete) the & in std::vector<ScanRule>& topPriorityRules;

If you want to keep only numbers then use /[^0-9]+/ instead of /[^a-zA-Z]+/

The Error is here

lastrow = wsPOR.Range("A" & Rows.Count).End(xlUp).Row + 1

wsPOR is a workbook and not a worksheet. If you are working with "Sheet1" of that workbook then try this

lastrow = wsPOR.Sheets("Sheet1").Range("A" & _
          wsPOR.Sheets("Sheet1").Rows.Count).End(xlUp).Row + 1

Similarly

wsPOR.Range("A2:G" & lastrow).Select

should be

wsPOR.Sheets("Sheet1").Range("A2:G" & lastrow).Select

For a precise answer to this question on "How to send data via intent from an Activity to Service", Is that you have to override the onStartCommand() method which is where you receive the intent object:

When you create a Service you should override the onStartCommand() method so if you closely look at the signature below, this is where you receive the intent object which is passed to it:

  public int onStartCommand(Intent intent, int flags, int startId)

So from an activity you will create the intent object to start service and then you place your data inside the intent object for example you want to pass a UserID from Activity to Service:

 Intent serviceIntent = new Intent(YourService.class.getName())
 serviceIntent.putExtra("UserID", "123456");
 context.startService(serviceIntent);

When the service is started its onStartCommand() method will be called so in this method you can retrieve the value (UserID) from the intent object for example

public int onStartCommand (Intent intent, int flags, int startId) {
    String userID = intent.getStringExtra("UserID");
    return START_STICKY;
}

Note: the above answer specifies to get an Intent with getIntent() method which is not correct in context of a service

#menu li { padding: 0px; }
#menu li a { margin: 0px; display: block; width: 100%; height: 100%; }

It may need some tweaking for IE6, but that's about how you do it.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

Truncate drops the decimal point.

This worked for me:

$("[id*=txtName]").on('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { e.preventDefault(); alert('Tab Pressed'); } });

Please take a read on my answer to a very similar question posted below. It should be clear that you should treat HttpClient instances as singletons and re-used across requests.

What is the overhead of creating a new HttpClient per call in a WebAPI client?

The command (given by Tomek) can't delete a file, if it is read only. therefore, one can use -

import os, sys
import stat

def del_evenReadonly(action, name, exc):
    os.chmod(name, stat.S_IWRITE)
    os.remove(name)

if  os.path.exists("test/qt_env"):
    shutil.rmtree('test/qt_env',onerror=del_evenReadonly)

Use Code::Blocks. It has everything you need and a very clean GUI.

cd "`dirname $(readlink -f ${0})`"

followings programs will execute,"one number is multiple of another" in

#include<stdio.h>
int main
{
int a,b;
printf("enter any two number\n");
scanf("%d%d",&a,&b);
if (a%b==0)
printf("this is  multiple number");
else if (b%a==0);
printf("this is multiple number");
else
printf("this is not multiple number");
return 0;
}

Radrails 3 is supposed to have it, Aptana Studio 3 will have it. Radrails is in beta, so thats kind of a downer, but none the less it is there to give'r a whirl.

    function urlCallback(url) {

            if (count < 1) {
                callback();
            }
        };
    }

    function loadScript(url) {
        var s = document.createElement('script');
        s.setAttribute('src', url);
        s.onload = urlCallback(url);
        document.head.appendChild(s);
    }

    for (var script of scripts) {

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

You can try using the following code to solve your problem:

 <activity
     android:name=".DonateNow"
     android:label="@string/title_activity_donate_now"
     android:screenOrientation="portrait"
     android:theme="@style/AppTheme"
     android:windowSoftInputMode="stateVisible|adjustPan">
 </activity>

Start Task Manager, click on the Processes tab, right-click on wscript.exe and select End Process, and confirm in the dialog that follows. This will terminate the wscript.exe that is executing your script.

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

Just sort the array in ascending order and print it backwards.

Arrays.sort(arr);
for(int i = arr.length-1; i >= 0 ; i--) {
    //print arr[i]
}

From the JSON standard:

An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.

(emphasis mine).

So, no you can't guarantee the order.

You probably shouldn't do this; you're breaking the basic pattern of how Make works. But here it is:

action:
        @echo action $(filter-out $@,$(MAKECMDGOALS))

%:      # thanks to chakrit
    @:    # thanks to William Pursell

EDIT:
To explain the first command,

$(MAKECMDGOALS) is the list of "targets" spelled out on the command line, e.g. "action value1 value2".

$@ is an automatic variable for the name of the target of the rule, in this case "action".

filter-out is a function that removes some elements from a list. So $(filter-out bar, foo bar baz) returns foo baz (it can be more subtle, but we don't need subtlety here).

Put these together and $(filter-out $@,$(MAKECMDGOALS)) returns the list of targets specified on the command line other than "action", which might be "value1 value2".

What is the real difference between one-to-many and many-to-one relationship?

There are conceptual differences between these terms that should help you visualize the data and also possible differences in the generated schema that should be fully understood. Mostly the difference is one of perspective though.

In a one-to-many relationship, the local table has one row that may be associated with many rows in another table. In the example from SQL for beginners, one Customer may be associated to many Orders.

In the opposite many-to-one relationship, the local table may have many rows that are associated with one row in another table. In our example, many Orders may be associated to one Customer. This conceptual difference is important for mental representation.

In addition, the schema which supports the relationship may be represented differently in the Customer and Order tables. For example, if the customer has columns id and name:

id,name
1,Bill Smith
2,Jim Kenshaw

Then for a Order to be associated with a Customer, many SQL implementations add to the Order table a column which stores the id of the associated Customer (in this schema customer_id:

id,date,amount,customer_id
10,20160620,12.34,1
11,20160620,7.58,1
12,20160621,158.01,2

In the above data rows, if we look at the customer_id id column, we see that Bill Smith (customer-id #1) has 2 orders associated with him: one for $12.34 and one for $7.58. Jim Kenshaw (customer-id #2) has only 1 order for $158.01.

What is important to realize is that typically the one-to-many relationship doesn't actually add any columns to the table that is the "one". The Customer has no extra columns which describe the relationship with Order. In fact the Customer might also have a one-to-many relationship with ShippingAddress and SalesCall tables and yet have no additional columns added to the Customer table.

However, for a many-to-one relationship to be described, often an id column is added to the "many" table which is a foreign-key to the "one" table -- in this case a customer_id column is added to the Order. To associated order #10 for $12.34 to Bill Smith, we assign the customer_id column to Bill Smith's id 1.

However, it is also possible for there to be another table that describes the Customer and Order relationship, so that no additional fields need to be added to the Order table. Instead of adding a customer_id field to the Order table, there could be Customer_Order table that contains keys for both the Customer and Order.

customer_id,order_id
1,10
1,11
2,12

In this case, the one-to-many and many-to-one is all conceptual since there are no schema changes between them. Which mechanism depends on your schema and SQL implementation.

Hope this helps.

Check out this page: https://developer.mozilla.org/En/DOM/Document.getElementsByName

document.getElementsByName('foo')[0]; // returns you element.

It has to be 'elements' and must return an array because more than one element could have the same name.

A more general approach to implement our own Comparator as below

Collections.sort(lst,new Comparator<Long>(){
                public int compare(Long o1, Long o2) {
                    return o2.compareTo(o1);
                }
            });

This command will create two files in /path/to/directory table_name.sql and table_name.txt.

The SQL file will contain the table creation schema and the txt file will contain the records of the mytable table with fields delimited by a comma.

mysqldump -u username -p -t  -T/path/to/directory dbname table_name --fields-terminated-by=','

I have use mkcert to create infinites *.dev.net subdomains & localhost with valid HTTPS/SSL certs (Windows 10 XAMPP & Linux Debian 10 Apache2)

I create the certs on Windows with mkcert v1.4.0 (execute CMD as Administrator):

mkcert -install
mkcert localhost "*.dev.net"

This create in Windows 10 this files (I will install it first in Windows 10 XAMPP)

localhost+1.pem
localhost+1-key.pem

Overwrite the XAMPP default certs:

copy "localhost+1.pem" C:\xampp\apache\conf\ssl.crt\server.crt
copy "localhost+1-key.pem"  C:\xampp\apache\conf\ssl.key\server.key

Now, in Apache2 for Debian 10, activate SSL & vhost_alias

a2enmod vhosts_alias
a2enmod ssl
a2ensite default-ssl
systemctl restart apache2

For vhost_alias add this Apache2 config:

nano /etc/apache2/sites-available/999-vhosts_alias.conf

With this content:

<VirtualHost *:80>
   UseCanonicalName Off
   ServerAlias *.dev.net
   VirtualDocumentRoot "/var/www/html/%0/"
</VirtualHost>

Add the site:

a2ensite 999-vhosts_alias

Copy the certs to /root/mkcert by SSH and let overwrite the Debian ones:

systemctl stop apache2

mv /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/certs/ssl-cert-snakeoil.pem.bak
mv /etc/ssl/private/ssl-cert-snakeoil.key /etc/ssl/private/ssl-cert-snakeoil.key.bak

cp "localhost+1.pem" /etc/ssl/certs/ssl-cert-snakeoil.pem
cp "localhost+1-key.pem" /etc/ssl/private/ssl-cert-snakeoil.key

chown root:ssl-cert /etc/ssl/private/ssl-cert-snakeoil.key
chmod 640 /etc/ssl/private/ssl-cert-snakeoil.key

systemctl start apache2

Edit the SSL config

nano /etc/apache2/sites-enabled/default-ssl.conf

At the start edit the file with this content:

<IfModule mod_ssl.c>
    <VirtualHost *:443>

            UseCanonicalName Off
            ServerAlias *.dev.net
            ServerAdmin webmaster@localhost

            # DocumentRoot /var/www/html/
            VirtualDocumentRoot /var/www/html/%0/

...

Last restart:

systemctl restart apache2

NOTE: don´t forget to create the folders for your subdomains in /var/www/html/

If you want the result to two decimal places you can do

// assuming you want to round to Infinity.
double tip = (long) (amount * percent + 0.5) / 100.0; 

This result is not precise but Double.toString(double) will correct for this and print one to two decimal places. However as soon as you perform another calculation, you can get a result which will not be implicitly rounded. ;)

It could also be a python version issue. I had to pick the right one to make it work.
