One more reason for this issue to happen is an earlier problem. When showing a new ViewController, instantiating the target ViewController directly will of course not load the prototype cells from the StoryBoard. The correct solution should always be to instantiate the view controller through the story board like this:

storyboard?.instantiateViewController(withIdentifier: "some_identifier")

my two cents for xcode 9.1 / swift 4.

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {

    override func viewDidLoad(){
        super.viewDidLoad()

        let when = DispatchTime.now() + 0.5

        DispatchQueue.main.asyncAfter(deadline: when, execute: { () -> Void in
            // to test after 05.secs... :)
            self.showPopover(base: self.view)

        })

}


func showPopover(base: UIView) {
    if let viewController = self.storyboard?.instantiateViewController(withIdentifier: "popover") as? PopOverViewController {

        let navController = UINavigationController(rootViewController: viewController)
        navController.modalPresentationStyle = .popover

        if let pctrl = navController.popoverPresentationController {
            pctrl.delegate = self

            pctrl.sourceView = base
            pctrl.sourceRect = base.bounds

            self.present(navController, animated: true, completion: nil)
        }
    }
}


@IBAction func onShow(sender: UIButton){
    self.showPopover(base: sender)
}

func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle{
    return .none
}

and experiment in:

func adaptivePresentationStyle...

    return .popover

or: return .pageSheet.... and so on..

for resizing my table I went with this solution in my tableview controller witch is perfectly fine:

[objectManager getObjectsAtPath:self.searchURLString
                         parameters:nil
                            success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                NSArray* results = [mappingResult array];
                                self.eventArray = results;
                                NSLog(@"Events number at first: %i", [self.eventArray count]);
                                CGRect newFrame = self.activityFeedTableView.frame;
                                newFrame.size.height = self.cellsHeight + 30.0;
                                self.activityFeedTableView.frame = newFrame;

                                self.cellsHeight = 0.0;

                            }
                            failure:^(RKObjectRequestOperation *operation, NSError *error) {
                                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                                                message:[error localizedDescription]
                                                                               delegate:nil
                                                                      cancelButtonTitle:@"OK"
                                                                      otherButtonTitles:nil];
                                [alert show];
                                NSLog(@"Hit error: %@", error);
                            }];

The resizing part is in a method but here is just so you can see it. Now the only problem I haveis resizing the scroll view in the other view controller as I have no idea when the tableview has finished resizing. At the moment I'm doing it with performSelector: afterDelay: but this is really not a good way to do it. Any ideas?

try this

[yourTableView setBounces:NO];

Here is the beginning of my response to your update:

Why does the content height of my UIWebView not change with rotation?.

Could it be that because your auto resize doesn't have the autoresizingMask for all directions?

Another suggestion before I come back for this, could you use a toolbar for your needs. It's a little simpler, will always be on the bottom, auto-rotates/positions. You can hide/show it at will etc. Kind of like this: http://cdn.artoftheiphone.com/wp-content/uploads/2009/01/yellow-pages-iphone-app-2.jpg

You may have looked at that option, but just throwing it out there.

Another idea, could you possibly detect what orientation you are rotating from, and just place the button programmatically to adjust for the tab bar. (This is possible with code)

Wrapping Richy's code I created a custom UIScrollView class that automates content resizing completely!

SBScrollView.h

@interface SBScrollView : UIScrollView
@end

SBScrollView.m:

@implementation SBScrollView
- (void) layoutSubviews
{
    CGFloat scrollViewHeight = 0.0f;
    self.showsHorizontalScrollIndicator = NO;
    self.showsVerticalScrollIndicator = NO;
    for (UIView* view in self.subviews)
    {
        if (!view.hidden)
        {
            CGFloat y = view.frame.origin.y;
            CGFloat h = view.frame.size.height;
            if (y + h > scrollViewHeight)
            {
                scrollViewHeight = h + y;
            }
        }
    }
    self.showsHorizontalScrollIndicator = YES;
    self.showsVerticalScrollIndicator = YES;
    [self setContentSize:(CGSizeMake(self.frame.size.width, scrollViewHeight))];
}
@end

How to use:
Simply import the .h file to your view controller and declare a SBScrollView instance instead of the normal UIScrollView one.

You are missing an equality:

var query = (from p in tblPersoon where p.id == 5 select p).Single();

where clause must result in a boolean.

OR you should not be using where at all:

var query = (from p in tblPersoon select p).Single();

Simply type conda update pandas in your preferred shell (on Windows, use cmd; if Anaconda is not added to your PATH use the Anaconda prompt). You can of course use Eclipse together with Anaconda, but you need to specify the Python-Path (the one in the Anaconda-Directory). See this document for a detailed instruction.

After migrating to PHP 5.6.5, the soap 1.2 did not work anymore. So I solved the problem by adding optional SSL parameters.

My error:

failed to load external entity

How to solve:

// options for ssl in php 5.6.5
$opts = array(
    'ssl' => array(
        'ciphers' => 'RC4-SHA',
        'verify_peer' => false,
        'verify_peer_name' => false
    )
);

// SOAP 1.2 client
$params = array(
    'encoding' => 'UTF-8',
    'verifypeer' => false,
    'verifyhost' => false,
    'soap_version' => SOAP_1_2,
    'trace' => 1,
    'exceptions' => 1,
    'connection_timeout' => 180,
    'stream_context' => stream_context_create($opts)
);

$wsdlUrl = $url . '?WSDL';
$oSoapClient = new SoapClient($wsdlUrl, $params);

You can add a filter for the nav_menu_css_class action in your functions.php file.

Example:

function atg_menu_classes($classes, $item, $args) {
  if($args->theme_location == 'secondary') {
    $classes[] = 'list-inline-item';
  }
  return $classes;
}
add_filter('nav_menu_css_class', 'atg_menu_classes', 1, 3);

In my case, the program was running fine, but after one day, I just ran into this problem without doing anything...

The solution was to manually add 'Main' as the Entry Point (before editing, the area was empty):

Updated Answer

If a programmer is interested in only parsing a table from a webpage, they can utilize the pandas method pandas.read_html.

Let's say we want to extract the GDP data table from the website: https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries

Then following codes does the job perfectly (No need of beautifulsoup and fancy html):

import pandas as pd
import requests

url = "https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries"

r = requests.get(url)
df_list = pd.read_html(r.text) # this parses all the tables in webpages to a list
df = df_list[0]
df.head()

Output

I have an idea too. C++ does have zero-overhead principle. But exceptions do not follow this principle, so sometimes they are turned off with compiler switch.

Let's look to this example:

#include <new>
#include <cstdio>
#include <cstdlib>

int main() {
    struct A {
        A() {
            printf("A()\n");
        }
        ~A() {
            printf("~A()\n");
        }
        char data[1000000000000000000] = {}; // some very big number
    };

    try {
        A *result = new A();
        printf("new passed: %p\n", result);
        delete result;
    } catch (std::bad_alloc) {
        printf("new failed\n");
    }
}

We allocate a big struct here, and check if allocation is successful, and delete it.

But if we have exceptions turned off, we can't use try block, and unable to handle new[] failure.

So how we can do that? Here is how:

#include <new>
#include <cstdio>
#include <cstdlib>

int main() {
    struct A {
        A() {
            printf("A()\n");
        }
        ~A() {
            printf("~A()\n");
        }
        char data[1000000000000000000] = {}; // some very big number
    };

    void *buf = malloc(sizeof(A));
    if (buf != nullptr) {
        A *result = new(buf) A();
        printf("new passed: %p\n", result);
        result->~A();
        free(result);
    } else {
        printf("new failed\n");
    }
}

• Use simple malloc
• Check if it is failed in a C way
• If it successful, we use placement new
• Manually call the destructor (we can't just call delete)
• call free, due we called malloc

UPD @Useless wrote a comment which opened to my view the existence of new(nothrow), which should be used in this case, but not the method I wrote before. Please don't use the code I wrote before. Sorry.

For everyone coming to this thread with fractional seconds in your timestamp use:

to_timestamp('2018-11-03 12:35:20.419000', 'YYYY-MM-DD HH24:MI:SS.FF')

try this:

ssh-add ~/.ssh/id_rsa

How does spark context in your application pick the value for spark master?

• You either provide it explcitly withing SparkConf while creating SC.
• Or it picks from the System.getProperties (where SparkSubmit earlier put it after reading your --master argument).

Now, SparkSubmit runs on the driver -- which in your case is the machine from where you're executing the spark-submit script. And this is probably working as expected for you too.

However, from the information you've posted it looks like you are creating a spark context in the code that is sent to the executor -- and given that there is no spark.master system property available there, it fails. (And you shouldn't really be doing so, if this is the case.)

Can you please post the GroupEvolutionES code (specifically where you're creating SparkContext(s)).

This is a simple one line function using rtrim, save separator and decimal point :

function myFormat($num,$dec)
 {
 return rtrim(rtrim(number_format($num,$dec),'0'),'.');
 }

Another way of viewing the full content of the cells in a pandas dataframe is to use IPython's display functions:

from IPython.display import HTML

HTML(df.to_html())

Yes there is. It is wrong. It won't work because it is wrong. Most browsers will only see one form.

If you have the XML stored inside a string variable you could use a StringReader:

var xml = @"<car/>";
var serializer = new XmlSerializer(typeof(Car));
using (var reader = new StringReader(xml))
{
    var car = (Car)serializer.Deserialize(reader);
}

The way I am doing is using Emacs with docker package installed. I would recommend Spacemacs version of Emacs. I would follow the following steps:

1) Install Emacs (Instruction) and install Spacemacs (Instruction)

2) Add docker in your .spacemacs file

3) Start Emacs

4) Find file (SPC+f+f) and type /docker:<container-id>:/<path of dir/file in the container>

5) Now your emacs will use the container environment to edit the files

This modified solution from above does not require explicit knowledge of the current database. It is then more flexible.

SELECT count(*) FROM information_schema.TABLES WHERE TABLE_NAME = 'yourtable' 
AND TABLE_SCHEMA in (SELECT DATABASE());

A very simple way to do so with IPython that worked for me in Visual Studio Code is to add the following:

{
    "key": "ctrl+space",
    "command": "jupyter.runallcells"
  }

to the keybindings.json that you can access by typing F1 and 'open keyboard shortcuts'.

You need to tell scp where to send the file. In your command that is not working:

scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~

You have not mentioned a remote server. scp uses : to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c from the host C to your local home directory.

The correct upload command, based on your comments, should be something like:

C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:

If you are running the command from your home directory, you can use a relative path:

C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:

You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:

C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/

The path is in the registry but usually you edit through this interface:

1. Go to Control Panel -> System -> System settings -> Environment Variables.
2. Scroll down in system variables until you find PATH.
3. Click edit and change accordingly.
4. BE SURE to include a semicolon at the end of the previous as that is the delimiter, i.e. c:\path;c:\path2
5. Launch a new console for the settings to take effect.

If SESSION_START_DATE_TIME is of type TIMESTAMP you may want to try using the SQL function TO_TIMESTAMP. Here is an example:

     SQL> CREATE TABLE t (ts TIMESTAMP);

     Table created.

     SQL> INSERT INTO t
       2       VALUES (
       3                 TO_TIMESTAMP (
       4                    '1/12/2012 5:03:27.221008 PM'
       5                   ,'mm/dd/yyyy HH:MI:SS.FF AM'
       6                 )
       7              );

     1 row created.

     SQL> SELECT *
       2    FROM t
       3   WHERE ts =
       4            TO_TIMESTAMP (
       5               '1/12/2012 5:03:27.221008 PM'
       6              ,'mm/dd/yyyy HH:MI:SS.FF AM'
       7            );

Your web form shouldn't have all of that markup (like the <html> tag). Since it has a master page, you just start with the content tag. Your aspx page should look like this:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebUI._Default" MasterPageFile="~/Site1.Master" %>

<asp:content id="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
   This is the body!
</asp:content>

When you're adding a new aspx page make sure to check "select master page" in the "add new item" dialog.

Briefly, the way I have done this is:

1. Read the file (a db dump eg $ mysqldump db > db.sql)

   $sql = file_get_contents(db.sql);
   

2. Import it using mysqli::multi_query

   if ($mysqli->multi_query($sql)) {
       $mysqli->close();
   } else {
       throw new Exception ($mysqli->error);
   }
   

Watch out mysqli_query supports async queries. More here: http://php.net/manual/en/mysqli.multi-query.php and here https://stackoverflow.com/a/6652908/2002493

Can use enumerate.

a = [1, 2, 3, 4]
b = [2, 3, 4, 5]

ab = [val * b[i] for i, val in enumerate(a)]

If you have downloaded these files locally then you can change following classes in bootstrap-social.css, just added border-radius: 50%;

.btn-social-icon.btn-lg{height:45px;width:45px;
   padding-left:0;padding-right:0; border-radius: 50%; }

And here is teh HTML

<a class="btn btn-social-icon btn-lg btn-twitter" >
   <i class="fa fa-twitter"></i>
</a>
<a class=" btn btn-social-icon btn-lg btn-facebook">
   <i class="fa fa-facebook sbg-facebook"></i>
</a>
<a class="btn btn-social-icon btn-lg btn-google-plus">
   <i class="fa fa-google-plus"></i>
</a>

It works smooth for me.

Non of the above answers worked for me so here is what I did eventually:

import React, { Component } from 'react';

/**
 * Component that alerts if you click outside of it
 */
export default class OutsideAlerter extends Component {
  constructor(props) {
    super(props);

    this.handleClickOutside = this.handleClickOutside.bind(this);
  }

  componentDidMount() {
    document.addEventListener('mousedown', this.handleClickOutside);
  }

  componentWillUnmount() {
    document.removeEventListener('mousedown', this.handleClickOutside);
  }

  /**
   * Alert if clicked on outside of element
   */
  handleClickOutside(event) {
    if (!event.path || !event.path.filter(item => item.className=='classOfAComponent').length) {
      alert('You clicked outside of me!');
    }
  }

  render() {
    return <div>{this.props.children}</div>;
  }
}

OutsideAlerter.propTypes = {
  children: PropTypes.element.isRequired,
};

Here is an optimized version of npinti's answer:

import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.JTextComponent;
import javax.swing.text.PlainDocument;
import java.awt.*;

public class TextComponentLimit extends PlainDocument
{
    private int charactersLimit;

    private TextComponentLimit(int charactersLimit)
    {
        this.charactersLimit = charactersLimit;
    }

    @Override
    public void insertString(int offset, String input, AttributeSet attributeSet) throws BadLocationException
    {
        if (isAllowed(input))
        {
            super.insertString(offset, input, attributeSet);
        } else
        {
            Toolkit.getDefaultToolkit().beep();
        }
    }

    private boolean isAllowed(String string)
    {
        return (getLength() + string.length()) <= charactersLimit;
    }

    public static void addTo(JTextComponent textComponent, int charactersLimit)
    {
        TextComponentLimit textFieldLimit = new TextComponentLimit(charactersLimit);
        textComponent.setDocument(textFieldLimit);
    }
}

To add a limit to your JTextComponent, simply write the following line of code:

JTextFieldLimit.addTo(myTextField, myMaximumLength);

Quick answer: change int testlib() to int testlib(void) to specify that the function takes no arguments.

A prototype is by definition a function declaration that specifies the type(s) of the function's argument(s).

A non-prototype function declaration like

int foo();

is an old-style declaration that does not specify the number or types of arguments. (Prior to the 1989 ANSI C standard, this was the only kind of function declaration available in the language.) You can call such a function with any arbitrary number of arguments, and the compiler isn't required to complain -- but if the call is inconsistent with the definition, your program has undefined behavior.

For a function that takes one or more arguments, you can specify the type of each argument in the declaration:

int bar(int x, double y);

Functions with no arguments are a special case. Logically, empty parentheses would have been a good way to specify that an argument but that syntax was already in use for old-style function declarations, so the ANSI C committee invented a new syntax using the void keyword:

int foo(void); /* foo takes no arguments */

A function definition (which includes code for what the function actually does) also provides a declaration. In your case, you have something similar to:

int testlib()
{
    /* code that implements testlib */
}

This provides a non-prototype declaration for testlib. As a definition, this tells the compiler that testlib has no parameters, but as a declaration, it only tells the compiler that testlib takes some unspecified but fixed number and type(s) of arguments.

If you change () to (void) the declaration becomes a prototype.

The advantage of a prototype is that if you accidentally call testlib with one or more arguments, the compiler will diagnose the error.

(C++ has slightly different rules. C++ doesn't have old-style function declarations, and empty parentheses specifically mean that a function takes no arguments. C++ supports the (void) syntax for consistency with C. But unless you specifically need your code to compile both as C and as C++, you should probably use the () in C++ and the (void) syntax in C.)

The compiler is telling you that there are problems starting at line 122 in the middle of that strange FBI-CIA warning message. That message is not valid C++ code and is NOT commented out so of course it will cause compiler errors. Try removing that entire message.

Also, I agree with In silico: you should always tell us what you tried and exactly what error messages you got.

This answer explains well as to why this problem occurs:

Xcode C++ :: Duplicate Symbols for Architecture x86_64

In my opinion you do not need to turn any of the flags off or change Xcode settings, re-read your code, and fix the problem. Changing the settings would just subside the inflammation not the cause.

You could also achieve the same result by using a Conditional Expression:

maxnum = run if run > value else value

a bit more flexible than max but admittedly longer to type.

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

angular.element(document).ready(function () {
    //your logic here
});

This is my solution

public static String removeDup(String inputString){
    if (inputString.length()<2) return inputString;
    if (inputString==null) return null;
    char[] inputBuffer=inputString.toCharArray();
    for (int i=0;i<inputBuffer.length;i++){
        for (int j=i+1;j<inputBuffer.length;j++){
            if (inputBuffer[i]==inputBuffer[j]){
                inputBuffer[j]=0;
            }
        }
    }
    String result=new String(inputBuffer);
    return result;
}

Tobu comments that:

This is implicit when doing a shallow clone.
This makes git clone --depth 1 the easiest way to save bandwidth.

And since Git 1.9.0 (February 2014), shallow clones support data transfer (push/pull), so that option is even more useful now.
See more at "Is git clone --depth 1 (shallow clone) more useful than it makes out?".

"Undoing" a shallow clone is detailed at "Convert shallow clone to full clone" (git 1.8.3+)

# unshallow the current branch
git fetch --unshallow

# for getting back all the branches (see Peter Cordes' comment)
git config remote.origin.fetch refs/heads/*:refs/remotes/origin/*
git fetch --unshallow

As Chris comments:

the magic line for getting missing branches to reverse --single-branch is (git v2.1.4):

git config remote.origin.fetch +refs/heads/*:refs/remotes/origin/*
git fetch --unshallow  

With Git 2.26 (Q1 2020), "git clone --recurse-submodules --single-branch" now uses the same single-branch option when cloning the submodules.

See commit 132f600, commit 4731957 (21 Feb 2020) by Emily Shaffer (nasamuffin).

clone: pass --single-branch during --recurse-submodules

^{Signed-off-by: Emily Shaffer
Acked-by: Jeff King}

Previously, performing "git clone --recurse-submodules --single-branch" resulted in submodules cloning all branches even though the superproject cloned only one branch.

Pipe --single-branch through the submodule helper framework to make it to 'clone' later on.

<table style="min-width:50px; max-width:150px;">
    <tr>
        <td style="min-width:50px">one</td>
        <td style="min-width:100px">two</td>
    </tr>
</table>

This works for me using an email script.

This seems weird, but you can try setting vertical-align: top in the CSS for the inputs. That fixes it in IE8, at least.

This is an answer based on jluckyiv's, but I think it is better and simpler to change Javascript as follows.

browser.loadUrl("javascript:HTMLOUT.processHTML(document.documentElement.outerHTML);");

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

This error occurs me when I use path.resolve(), to set up 'entry' and 'output' settings. entry: path.resolve(__dirname + '/app.jsx'). Just try entry: __dirname + '/app.jsx'

Manipulating arrays in this way is error prone, as you've discovered. A better option may be to use a LinkedList in your situation. With a linked list, and all Java collections, array management is handled internally so you don't have to worry about moving elements around. With a LinkedList you just call remove and then addLast and the you're done.

You should look at the members of the thrown exception, particularly .Message and .InnerException.

I would also see whether or not the documentation for InvokeMethod tells you whether it throws some more specialized Exception class than Exception - such as the Win32Exception suggested by @Preet. Catching and just looking at the Exception base class may not be particularly useful.

Given your current table structure this is not currently possible in DynamoDB. The huge challenge is to understand that the Hash key of the table (partition) should be treated as creating separate tables. In some ways this is really powerful (think of partition keys as creating a new table for each user or customer, etc...).

Queries can only be done in a single partition. That's really the end of the story. This means if you want to query by date (you'll want to use msec since epoch), then all the items you want to retrieve in a single query must have the same Hash (partition key).

I should qualify this. You absolutely can scan by the criterion you are looking for, that's no problem, but that means you will be looking at every single row in your table, and then checking if that row has a date that matches your parameters. This is really expensive, especially if you are in the business of storing events by date in the first place (i.e. you have a lot of rows.)

You may be tempted to put all the data in a single partition to solve the problem, and you absolutely can, however your throughput will be painfully low, given that each partition only receives a fraction of the total set amount.

The best thing to do is determine more useful partitions to create to save the data:

• Do you really need to look at all the rows, or is it only the rows by a specific user?

• Would it be okay to first narrow down the list by Month, and do multiple queries (one for each month)? Or by Year?

• If you are doing time series analysis there are a couple of options, change the partition key to something computated on PUT to make the query easier, or use another aws product like kinesis which lends itself to append-only logging.

I am also faced same issue in Dialog.. because I am using setOnKeyListener.. But I set default return true. After change like below code it working fine for me..

    mDialog.setOnKeyListener(new Dialog.OnKeyListener() {

        @Override
        public boolean onKey(DialogInterface arg0, int keyCode,
                             KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                mDialog.dismiss();
                return true;
            }
            return false;//this line is important 

        }
    });

You can use the following:

    /// <summary>
    /// Serializes an object.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="serializableObject"></param>
    /// <param name="fileName"></param>
    public void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }
    }


    /// <summary>
    /// Deserializes an xml file into an object list
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="fileName"></param>
    /// <returns></returns>
    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                }
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }

        return objectOut;
    }

function  form_submit(form_id,filename){
    $.post(filename,$("#"+form_id).serialize(), function(data){
        alert(data);
    });
}

It will post the form data on your given file name via AJAX.

Surprised I haven't seen this one liner here:

datetime.datetime.now().hour == 8

you may also want to look at

var hours = (datevalue1 - datevalue2).TotalHours;

Then there's the way of expressing your 'if' construct more tersely:

FOO='default'
[ -n "${VARIABLE}" ] && FOO=${VARIABLE}

In regards to JavaScript:

The === operator works the same as the == operator, but it requires that its operands have not only the same value, but also the same data type.

For example, the sample below will display 'x and y are equal', but not 'x and y are identical'.

var x = 4;
var y = '4';
if (x == y) {
    alert('x and y are equal');
}
if (x === y) {
    alert('x and y are identical');
}

Even though this is old and answered, i´d like to share the solution i made out of it 2020

it comes with the flexibility to run at anytime and run a callback if greater and or smaller the specified mbps

you can start the test anywhere after you included the testConnectionSpeed Object by running the testConnectionSpeed.run(mbps, morefunction, lessfunction)

for example:

var testConnectionSpeed = {
  imageAddr : "https://upload.wikimedia.org/wikipedia/commons/a/a6/Brandenburger_Tor_abends.jpg", // this is just an example, you rather want an image hosted on your server
  downloadSize : 2707459, // this must match with the image above
  run:function(mbps_max,cb_gt,cb_lt){
    testConnectionSpeed.mbps_max = parseFloat(mbps_max) ? parseFloat(mbps_max) : 0;
    testConnectionSpeed.cb_gt = cb_gt;
    testConnectionSpeed.cb_lt = cb_lt;
    testConnectionSpeed.InitiateSpeedDetection();
  },
  InitiateSpeedDetection: function() {
    window.setTimeout(testConnectionSpeed.MeasureConnectionSpeed, 1);
  },
  result:function(){
    var duration = (endTime - startTime) / 1000;
    var bitsLoaded = testConnectionSpeed.downloadSize * 8;
    var speedBps = (bitsLoaded / duration).toFixed(2);
    var speedKbps = (speedBps / 1024).toFixed(2);
    var speedMbps = (speedKbps / 1024).toFixed(2);
    if(speedMbps >= (testConnectionSpeed.max_mbps ? testConnectionSpeed.max_mbps : 1) ){
      testConnectionSpeed.cb_gt ? testConnectionSpeed.cb_gt(speedMbps) : false;
    }else {
      testConnectionSpeed.cb_lt ? testConnectionSpeed.cb_lt(speedMbps) : false;
    }
  },
  MeasureConnectionSpeed:function() {
    var download = new Image();
    download.onload = function () {
        endTime = (new Date()).getTime();
        testConnectionSpeed.result();
    }
    startTime = (new Date()).getTime();
    var cacheBuster = "?nnn=" + startTime;
    download.src = testConnectionSpeed.imageAddr + cacheBuster;
  }
}




// start test immediatly, you could also call this on any event or whenever you want
testConnectionSpeed.run(1.5, function(mbps){console.log(">= 1.5Mbps ("+mbps+"Mbps)")}, function(mbps){console.log("< 1.5Mbps("+mbps+"Mbps)")} )

I used this successfuly to load lowres media for slow internet connections. You have to play around a bit because on the one hand, the larger the image, the more reasonable the test, on the other hand the test will take way much longer for slow connection and in my case I especially did not want slow connection users to load lots of MBs.

Use it like this, should work:

 <a routerLink="/Service/Sign_in"><button class="btn btn-success pull-right" > Add Customer</button></a>

You can also use router.navigateByUrl('..') like this:

<button type="button" class="btn btn-primary-outline pull-right" (click)="btnClick();"><i class="fa fa-plus"></i> Add</button>    

import { Router } from '@angular/router';

btnClick= function () {
        this.router.navigateByUrl('/user');
};

Update 1

You have to inject Router in the constructor like this:

constructor(private router: Router) { }

only then you are able to use this.router. Remember also to import RouterModule in your module.

Update 2

Now, After Angular v4 you can directly add routerLink attribute on the button (As mentioned by @mark in comment section) like below (No "'/url?" since Angular 6, when a Route in RouterModule exists) -

 <button [routerLink]="'url'"> Button Label</button>

var index = Array.FindIndex(stringArray, x => x == value)

If there is no ORDER BY clause, then TOP 100 PERCENT is redundant. (As you mention, this was the 'trick' with views)

[Hopefully the optimizer will optimize this away.]

If you don't have a problem integrating a small batch application, there is this program called Cmdow.exe that will allow you to hide console windows based on console title.

Console.Title = "MyConsole";
System.Diagnostics.Process HideConsole = new System.Diagnostics.Process();
HideConsole.StartInfo.UseShellExecute = false;
HideConsole.StartInfo.Arguments = "MyConsole /hid";
HideConsole.StartInfo.FileName = "cmdow.exe";
HideConsole.Start();

Add the exe to the solution, set the build action to "Content", set Copy to Output Directory to what suits you, and cmdow will hide the console window when it is ran.

To make the console visible again, you just change the Arguments

HideConsole.StartInfo.Arguments = "MyConsole /Vis";

Or... you could simply use inverted logic. Let false mean true and vice versa.

Code sample

// bool[] isVisible = Enumerable.Repeat(true, 1000000).ToArray();
bool[] isHidden = new bool[1000000]; // Crazy-fast initialization!

// if (isVisible.All(v => v))
if (isHidden.All(v => !v))
{
    // Do stuff!
}

Everyone is talking about this like they can be hacked over the internet. As already stated, limiting attempts makes it impossible to crack a password over the Internet and has nothing to do with the hash.

The salt is a must, but the complexity or multiple salts doesn't even matter. Any salt alone stops the attacker from using a premade rainbow table. A unique salt per user stops the attacker from creating a new rainbow table to use against your entire user base.

The security really comes into play when the entire database is compromised and a hacker can then perform 100 million password attempts per second against the md5 hash. SHA512 is about 10,000 times slower. A complex password with today's power could still take 100 years to bruteforce with md5 and would take 10,000 times as long with SHA512. The salts don't stop a bruteforce at all as they always have to be known, which if the attacker downloaded your database, he probably was in your system anyway.

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

Easiest way

$('#yourform *').prop('readonly', true);

You can also go to Notepad++ and do the following steps:

The Array.prototype property represents the prototype for the Array constructor and allows you to add new properties and methods to all Array objects. we can create a prototype for this purpose

Array.prototype.has_element = function(element) {
    return $.inArray( element, this) !== -1;
};

And then use it like this

var numbers= [1, 2, 3, 4];
numbers.has_element(3) => true
numbers.has_element(10) => false

See the Demo below

Array.prototype.has_element = function(element) {_x000D_
  return $.inArray(element, this) !== -1;_x000D_
};_x000D_
_x000D_
_x000D_
_x000D_
var numbers = [1, 2, 3, 4];_x000D_
console.log(numbers.has_element(3));_x000D_
console.log(numbers.has_element(10));

Small +1 to kshark27's answer to make it dynamic:

#include <QTime>

void delay( int millisecondsToWait )
{
    QTime dieTime = QTime::currentTime().addMSecs( millisecondsToWait );
    while( QTime::currentTime() < dieTime )
    {
        QCoreApplication::processEvents( QEventLoop::AllEvents, 100 );
    }
}

--EDIT-- It looks like I took his question heading too literally - he was asking for an array of ints rather than a List --EDIT ENDS--

Yet another helper method...

private static int[] StringToIntArray(string myNumbers)
{
    List<int> myIntegers = new List<int>();
    Array.ForEach(myNumbers.Split(",".ToCharArray()), s =>
    {
        int currentInt;
        if (Int32.TryParse(s, out currentInt))
            myIntegers.Add(currentInt);
    });
    return myIntegers.ToArray();
}

quick test code for it, too...

static void Main(string[] args)
{
    string myNumbers = "1,2,3,4,5";
    int[] myArray = StringToIntArray(myNumbers);
    Console.WriteLine(myArray.Sum().ToString()); // sum is 15.

    myNumbers = "1,2,3,4,5,6,bad";
    myArray = StringToIntArray(myNumbers);
    Console.WriteLine(myArray.Sum().ToString()); // sum is 21

    Console.ReadLine();
}

Ok, I feel a bit stupid here... what's the reason not to just do it with something like
[(a+1,b) for (a,b) in enumerate(r)] ? If you won't function, no problem either:

>>> r = range(2000, 2005)
>>> [(a+1,b) for (a,b) in enumerate(r)]
[(1, 2000), (2, 2001), (3, 2002), (4, 2003), (5, 2004)]

>>> enumerate1 = lambda r:((a+1,b) for (a,b) in enumerate(r)) 

>>> list(enumerate1(range(2000,2005)))   # note - generator just like original enumerate()
[(1, 2000), (2, 2001), (3, 2002), (4, 2003), (5, 2004)]

df2 = df1.filter("Status=2")
     .filter("Status=3");

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

I'd simply point them to the Mozilla Closures page. It's the best, most concise and simple explanation of closure basics and practical usage that I've found. It is highly recommended to anyone learning JavaScript.

And yes, I'd even recommend it to a 6-year old -- if the 6-year old is learning about closures, then it's logical they're ready to comprehend the concise and simple explanation provided in the article.

You can encapsulate your block of code with a try ... catch statement, and when you run your code, if the column doesn't exist it will throw an exception. You can then figure out what specific exception it throws and have it handle that specific exception in a different way if you so desire, such as returning "Column Not Found".

The #! line tells the kernel (specifically, the implementation of the execve system call) that this program is written in an interpreted language; the absolute pathname that follows identifies the interpreter. Programs compiled to machine code begin with a different byte sequence -- on most modern Unixes, 7f 45 4c 46 (^?ELF) that identifies them as such.

You can put an absolute path to any program you want after the #!, as long as that program is not itself a #! script. The kernel rewrites an invocation of

./script arg1 arg2 arg3 ...

where ./script starts with, say, #! /usr/bin/perl, as if the command line had actually been

/usr/bin/perl ./script arg1 arg2 arg3

Or, as you have seen, you can use #! /bin/sh to write a script intended to be interpreted by sh.

The #! line is only processed if you directly invoke the script (./script on the command line); the file must also be executable (chmod +x script). If you do sh ./script the #! line is not necessary (and will be ignored if present), and the file does not have to be executable. The point of the feature is to allow you to directly invoke interpreted-language programs without having to know what language they are written in. (Do grep '^#!' /usr/bin/* -- you will discover that a great many stock programs are in fact using this feature.)

Here are some rules for using this feature:

• The #! must be the very first two bytes in the file. In particular, the file must be in an ASCII-compatible encoding (e.g. UTF-8 will work, but UTF-16 won't) and must not start with a "byte order mark", or the kernel will not recognize it as a #! script.
• The path after #! must be an absolute path (starts with /). It cannot contain space, tab, or newline characters.
• It is good style, but not required, to put a space between the #! and the /. Do not put more than one space there.
• You cannot put shell variables on the #! line, they will not be expanded.
• You can put one command-line argument after the absolute path, separated from it by a single space. Like the absolute path, this argument cannot contain space, tab, or newline characters. Sometimes this is necessary to get things to work (#! /usr/bin/awk -f), sometimes it's just useful (#! /usr/bin/perl -Tw). Unfortunately, you cannot put two or more arguments after the absolute path.
• Some people will tell you to use #! /usr/bin/env interpreter instead of #! /absolute/path/to/interpreter. This is almost always a mistake. It makes your program's behavior depend on the $PATH variable of the user who invokes the script. And not all systems have env in the first place.
• Programs that need setuid or setgid privileges can't use #!; they have to be compiled to machine code. (If you don't know what setuid is, don't worry about this.)

Regarding csh, it relates to sh roughly as Nutrimat Advanced Tea Substitute does to tea. It has (or rather had; modern implementations of sh have caught up) a number of advantages over sh for interactive usage, but using it (or its descendant tcsh) for scripting is almost always a mistake. If you're new to shell scripting in general, I strongly recommend you ignore it and focus on sh. If you are using a csh relative as your login shell, switch to bash or zsh, so that the interactive command language will be the same as the scripting language you're learning.

Here an idea to simplify the syntax:

public class IgnoreCase
{
    private readonly string _value;

    public IgnoreCase(string s)
    {
        _value = s;
    }

    protected bool Equals(IgnoreCase other)
    {
        return this == other;
    }

    public override bool Equals(object obj)
    {
        return obj != null &&
               (ReferenceEquals(this, obj) || (obj.GetType() == GetType() && this == (IgnoreCase) obj));
    }

    public override int GetHashCode()
    {
        return _value?.GetHashCode() ?? 0;
    }

    public static bool operator ==(IgnoreCase a, IgnoreCase b)
    {
        return string.Equals(a, b, StringComparison.OrdinalIgnoreCase);
    }

    public static bool operator !=(IgnoreCase a, IgnoreCase b)
    {
        return !(a == b);
    }

    public static implicit operator string(IgnoreCase s)
    {
        return s._value;
    }

    public static implicit operator IgnoreCase(string s)
    {
        return new IgnoreCase(s);
    }
}

Usable like:

Console.WriteLine((IgnoreCase) "a" == "b"); // false
Console.WriteLine((IgnoreCase) "abc" == "abC"); // true
Console.WriteLine((IgnoreCase) "Abc" == "aBc"); // true
Console.WriteLine((IgnoreCase) "ABC" == "ABC"); // true

Here's my script, which basically counts the number of lines, then appends, then counts them again so you have evidence it worked.

shortPath  = "../file_to_be_appended"
short = open(shortPath, 'r')

## this counts how many line are originally in the file:
long_path = "../file_to_be_appended_to" 
long = open(long_path, 'r')
for i,l in enumerate(long): 
    pass
print "%s has %i lines initially" %(long_path,i)
long.close()

long = open(long_path, 'a') ## now open long file to append
l = True ## will be a line
c = 0 ## count the number of lines you write
while l: 
    try: 
        l = short.next() ## when you run out of lines, this breaks and the except statement is run
        c += 1
        long.write(l)

    except: 
        l = None
        long.close()
        print "Done!, wrote %s lines" %c 

## finally, count how many lines are left. 
long = open(long_path, 'r')
for i,l in enumerate(long): 
    pass
print "%s has %i lines after appending new lines" %(long_path, i)
long.close()

You can load the text file into a textfile Hive table and then insert the data from this table into your sequencefile.

Start with a tab delimited file:

% cat /tmp/input.txt
a       b
a2      b2

create a sequence file

hive> create table test_sq(k string, v string) stored as sequencefile;

try to load; as expected, this will fail:

hive> load data local inpath '/tmp/input.txt' into table test_sq;

But with this table:

hive> create table test_t(k string, v string) row format delimited fields terminated by '\t' stored as textfile;

The load works just fine:

hive> load data local inpath '/tmp/input.txt' into table test_t;
OK
hive> select * from test_t;
OK
a       b
a2      b2

Now load into the sequence table from the text table:

insert into table test_sq select * from test_t;

Can also do load/insert with overwrite to replace all.

Here's a module for calculating SHA1 hashes that is usable for Excel formulas eg. '=SHA1HASH("test")'. To use it, make a new module called 'module_sha1' and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells.

If it doesnt work, please be specific in what way your compilation fails, specifically post the error messages Eclipse returns, and i will know what to do about it.

UUID schemes generally use not only a pseudo-random element, but also the current system time, and some sort of often-unique hardware ID if available, such as a network MAC address.

The whole point of using UUID is that you trust it to do a better job of providing a unique ID than you yourself would be able to do. This is the same rationale behind using a 3rd party cryptography library rather than rolling your own. Doing it yourself may be more fun, but it's typically less responsible to do so.

I don't yet see a viable answer for 2.7 which doesn't require installing additional dependencies and also starts from the file's directory. It's not nice as a single-line solution, but there's nothing wrong with using the standard utilities.

import os

grandparent_dir = os.path.abspath(  # Convert into absolute path string
    os.path.join(  # Current file's grandparent directory
        os.path.join(  # Current file's parent directory
            os.path.dirname(  # Current file's directory
                os.path.abspath(__file__)  # Current file path
            ),
            os.pardir
        ),
        os.pardir
    )
)

print grandparent_dir

And to prove it works, here I start out in ~/Documents/notes just so that I show the current directory doesn't influence outcome. I put the file grandpa.py with that script in a folder called "scripts". It crawls up to the Documents dir and then to the user dir on a Mac.

(testing)AlanSE-OSX:notes AlanSE$ echo ~/Documents/scripts/grandpa.py 
/Users/alancoding/Documents/scripts/grandpa.py
(testing)AlanSE-OSX:notes AlanSE$ python2.7 ~/Documents/scripts/grandpa.py 
/Users/alancoding

This is the obvious extrapolation of the answer for the parent dir. Better to use a general solution than a less-good solution in fewer lines.

I found that I needed to group by the month and year so neither of the above worked for me. Instead I used date_format

SELECT date
FROM blog 
GROUP BY DATE_FORMAT(date, "%m-%y")
ORDER BY YEAR(date) DESC, MONTH(date) DESC 

I would do it like this:

$('body').on('hidden.bs.modal', '#myModal', function(){ //this call your method });

The rest has already been written by others. I also recommend reading the documentation:jquery - on method

I solved this by writing a debounce decorator. The problem described could be solved by applying the @debounceAccessor to the property's set accessor.

I've also supplied an additional debounce decorator for methods, which can be useful for other occasions.

This makes it very easy to debounce a property or a method. The parameter is the number of milliseconds the debounce should last, 100 ms in the example below.

@debounceAccessor(100)
set myProperty(value) {
  this._myProperty = value;
}


@debounceMethod(100)
myMethod (a, b, c) {
  let d = a + b + c;
  return d;
}

And here's the code for the decorators:

function debounceMethod(ms: number, applyAfterDebounceDelay = false) {

  let timeoutId;

  return function (target: Object, propName: string, descriptor: TypedPropertyDescriptor<any>) {
    let originalMethod = descriptor.value;
    descriptor.value = function (...args: any[]) {
      if (timeoutId) return;
      timeoutId = window.setTimeout(() => {
        if (applyAfterDebounceDelay) {
          originalMethod.apply(this, args);
        }
        timeoutId = null;
      }, ms);

      if (!applyAfterDebounceDelay) {
        return originalMethod.apply(this, args);
      }
    }
  }
}

function debounceAccessor (ms: number) {

  let timeoutId;

  return function (target: Object, propName: string, descriptor: TypedPropertyDescriptor<any>) {
    let originalSetter = descriptor.set;
    descriptor.set = function (...args: any[]) {
      if (timeoutId) return;
      timeoutId = window.setTimeout(() => {
        timeoutId = null;
      }, ms);
      return originalSetter.apply(this, args);
    }
  }
}

I added an additional parameter for the method decorator which let's you trigger the method AFTER the debounce delay. I did that so I could for instance use it when coupled with mouseover or resize events, where I wanted the capturing to occur at the end of the event stream. In this case however, the method won't return a value.

Have you tried to remove "pytrace=True" ?

pytest.fail(exc, pytrace=True) # before
pytest.fail(exc) # after

Have you tried to run with '--fulltrace' ?

• zz - move current line to the middle of the screen
  (Careful with zz, if you happen to have Caps Lock on accidentally, you will save and exit vim!)
• zt - move current line to the top of the screen
• zb - move current line to the bottom of the screen

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

also works. First create a JFrame called frame, then add this code underneath.

Neither of them worked for me for some reason.

I figured it out that for some reason python doesn't read %s. So use (?) instead of %S in you SQL Code.

And finally this worked for me.

   cursor.execute ("update tablename set columnName = (?) where ID = (?) ",("test4","4"))
   connect.commit()

Spaces are horrible in filenames or directory names.

The correct syntax for this is to include every directory name that includes spaces, in double quotes

cmd /c C:\"Program Files"\"Microsoft Visual Studio 9.0"\Common7\IDE\devenv.com mysolution.sln /build "release|win32"

All the workaround mentioned above may work or may not work, in most cases it will not work. I have given the solution here

Currently I am working on Angular and Web API(.net Core) and came across CORS issue explained below

The solution provided above will always work. With 'OPTIONS' request it is really necessary to enable 'Anonymous Authentication'. With the solution mentioned here you don't have to do all the steps mentioned above, like IIS settings.

Anyways someone marked my above post as duplicate with this post, but I can see that this post is only to enable CORS in ASP.net Core, but my post is related to, Enabling and implementing CORS in ASP.net Core and Angular.

This is because ASP.NET it changing the Id of your textbox, if you run your page, and do a view source, you will see the text box id is something like

ctl00_ContentColumn_txt_model_code

There are a few ways round this:

Use the actual control name:

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

use the ClientID property within ASP script tags

document.getElementById('<%= txt_model_code.ClientID %>').value;

Or if you are running .NET 4 you can use the new ClientIdMode property, see this link for more details.

http://weblogs.asp.net/scottgu/archive/2010/03/30/cleaner-html-markup-with-asp-net-4-web-forms-client-ids-vs-2010-and-net-4-0-series.aspx1

You can also use interface builder if you don't want to make the adjustments in code. Here I left align the text and also indent it some:

Don't forget you can also align an image in the button too.:

// Merge object2 into object1, recursively

$.extend( true, object1, object2 );

// Merge object2 into object1

$.extend( object1, object2 );

Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:

LIVE DEMO

<div class="circle"></div>

CSS:

.circle, .circle:before{
  position:absolute;
  border-radius:150px;  
}
.circle{  
  width:200px;
  height:200px;
  z-index:0;
  margin:11%;
  padding:40px;
  background: hsla(0, 100%, 100%, 0.6);   
}
.circle:before{
  content:'';
  display:block;
  z-index:-1;  
  width:200px;
  height:200px;

  padding:44px;
  border: 6px solid hsla(0, 100%, 100%, 0.6);
  /* 4px more padding + 6px border = 10 so... */  
  top:-10px;
  left:-10px; 
}

The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.

As has been mentioned in other answers, there is no pure HTML5 way to do this.

If you are already using JQuery, then this should do what you need:

$(document).ready(function() {_x000D_
  $('#ourForm').submit(function(e){_x000D_
      var form = this;_x000D_
      e.preventDefault();_x000D_
      // Check Passwords are the same_x000D_
      if( $('#pass1').val()==$('#pass2').val() ) {_x000D_
          // Submit Form_x000D_
          alert('Passwords Match, submitting form');_x000D_
          form.submit();_x000D_
      } else {_x000D_
          // Complain bitterly_x000D_
          alert('Password Mismatch');_x000D_
          return false;_x000D_
      }_x000D_
  });_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form id="ourForm">_x000D_
    <input type="password" name="password" id="pass1" placeholder="Password" required>_x000D_
    <input type="password" name="password" id="pass2" placeholder="Repeat Password" required>_x000D_
    <input type="submit" value="Go">_x000D_
</form>

Python doesn't have matrices. You can use a list of lists or NumPy

I agree with Duncan ...I have tried it with mutable object but still get the same problem... I got a simple solution to this... use ListIterator instead Iterator and use set method of ListIterator

ListIterator<Integer> i = a.listIterator();
//changed the value of first element in List
Integer x =null;
        if(i.hasNext()) {
            x = i.next();
            x = Integer.valueOf(9);
        }
    //set method sets the recent iterated element in ArrayList
    i.set(x);
        //initialized the iterator again and print all the elements
        i = a.listIterator();
        while(i.hasNext())
        System.out.print(i.next());

But this constraints me to use this only for ArrayList only which can use ListIterator...i will have same problem with any other Collection

Public SUB test()
    Dim mdate As Date
    mdate = now()
    MsgBox (Round(CDbl(mdate), 0))
End SUB

We can use iterator to filter out the array entries instead of creating a new  Array. 

'public static void removeNullsFrom(JSONArray array) throws JSONException {
                if (array != null) {
                    Iterator<Object> iterator = array.iterator();
                    while (iterator.hasNext()) {
                        Object o = iterator.next();
                        if (o == null || o == JSONObject.NULL) {
                            iterator.remove();
                        }
                    }
                }
            }'

In django 2.2 this is explained here

https://docs.djangoproject.com/en/2.2/howto/overriding-templates/

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

INSTALLED_APPS = [
    ...,
    'blog',
    ...,
]

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        ...
    },
]

if you want to get the whole period:

    from sqlalchemy import and_, func

    query = DBSession.query(User).filter(and_(func.date(User.birthday) >= '1985-01-17'),\
                                              func.date(User.birthday) <= '1988-01-17'))

That means range: 1985-01-17 00:00 - 1988-01-17 23:59

if (in_array($id,$user_access_arr)==0)
{
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));
}

There is no need to explicitly check $?. Just do:

ps aux | grep some_proces[s] > /tmp/test.txt && echo 1 || echo 0 

Note that this relies on echo not failing, which is certainly not guaranteed. A more reliable way to write this is:

if ps aux | grep some_proces[s] > /tmp/test.txt; then echo 1; else echo 0; fi

  ...

Syntax: rsync <file_/_folder_list> <source> <target>

Folder names (here, WITH a trailing /; e.g. Cancer - Evolution/) are in a folder list file (e.g.: cm_folder_list_test):

# /mnt/Vancouver/projects/ie/claws/data/cm_folder_list_test
# test file: 2019-04-24
Cancer/
Cancer - Evolution/
Cancer - Genomic Variants/
Cancer - Metastasis (EMT Transition ...)/
Cancer Pathways, Networks/
Catabolism - Autophagy; Phagosomes; Mitophagy/
Catabolism - Lysosomes/

If you don't include those trailing /, the rsync'd target folders are created, but are empty.

Those folder names are appended to the rest of their path (/home/victoria/Mail/2_RESEARCH - NEWS), thus providing the complete folder path to rsync; e.g.: /home/victoria/Mail/2_RESEARCH - NEWS/Cancer - Evolution/.

Note that you also need to use --files-from= ..., NOT --include-from= ...

rsync -aqP --delete --files-from=/mnt/Vancouver/projects/ie/claws/data/cm_folder_list_test "/home/victoria/Mail/2_RESEARCH - NEWS" $IN/

(In my BASH script, I defined variable $IN as follows.)

BASEDIR="/mnt/Vancouver/projects/ie/claws"
IN=$BASEDIR/data/test/input

rsync options used:

 -a  :   archive: equals -rlptgoD (no -H,-A,-X)
    -r  :   recursive
    -l  :   copy symlinks as symlinks
    -p  :   preserve permissions
    -t  :   preserve modification times 
    -g  :   preserve group 
    -o  :   preserve owner (super-user only) 
    -D  :   same as --devices --specials 
  -q  :   quiet (https://serverfault.com/questions/547106/run-totally-silent-rsync)

  --delete
    This  tells  rsync to delete extraneous files from the RECEIVING SIDE (ones
    that AREN’T ON THE SENDING SIDE), but only for the directories that are
    being synchronized.  You must have asked rsync to send the whole directory
    (e.g.  "dir" or "dir/") without using a wildcard for the directory’s contents
    (e.g. "dir/*") since the wildcard is expanded by the shell and rsync thus
    gets a request to transfer individual files, not the files’ parent directory.
    Files  that  are  excluded  from  the transfer are also excluded from being
    deleted unless you use the --delete-excluded option or mark the rules as
    only matching on the sending side (see the include/exclude modifiers in the
    FILTER RULES section).  ...

 7698         30          6 --- 6 records in table for dept 30

Here we are getting count for respective deptno. As for deptno 10 we have 4 records in table emp similar results for deptno 20 and 30 also.

You can define a boolean and change it to false when you want to stop handler. Like this..

boolean stop = false;

handler.postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..

        if (!stop) {
            handler.postDelayed(this, delay);
        }
    }
}, delay);

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

I think we can answer it much more succinctly. I answered a related question, and copying my answer from there

But first, an NP-hard problem is a problem for which we cannot prove that a polynomial time solution exists. NP-hardness of some "problem-P" is usually proven by converting an already proven NP-hard problem to the "problem-P" in polynomial time.

To answer the rest of question, you first need to understand which NP-hard problems are also NP-complete. If an NP-hard problem belongs to set NP, then it is NP-complete. To belong to set NP, a problem needs to be

(i) a decision problem,
(ii) the number of solutions to the problem should be finite and each solution should be of polynomial length, and
(iii) given a polynomial length solution, we should be able to say whether the answer to the problem is yes/no

Now, it is easy to see that there could be many NP-hard problems that do not belong to set NP and are harder to solve. As an intuitive example, the optimization-version of traveling salesman where we need to find an actual schedule is harder than the decision-version of traveling salesman where we just need to determine whether a schedule with length <= k exists or not.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

You can also use plt.setp as follows:

import matplotlib.pyplot as plt
import seaborn as sns

plot=sns.barplot(data=df,  x=" ", y=" ")
plt.setp(plot.get_xticklabels(), rotation=90)

to rotate the labels 90 degrees.

A polyfill is a shim which replaces the original call with the call to a shim.

For example, say you want to use the navigator.mediaDevices object, but not all browsers support this. You could imagine a library that provided a shim which you might use like this:

<script src="js/MediaShim.js"></script>
<script>
    MediaShim.mediaDevices.getUserMedia(...);
</script>

In this case, you are explicitly calling a shim instead of using the original object or method. The polyfill, on the other hand, replaces the objects and methods on the original objects.

For example:

<script src="js/adapter.js"></script>
<script>
    navigator.mediaDevices.getUserMedia(...);
</script>

In your code, it looks as though you are using the standard navigator.mediaDevices object. But really, the polyfill (adapter.js in the example) has replaced this object with its own one.

The one it has replaced it with is a shim. This will detect if the feature is natively supported and use it if it is, or it will work around it using other APIs if it is not.

So a polyfill is a sort of "transparent" shim. And this is what Remy Sharp (who coined the term) meant when saying "if you removed the polyfill script, your code would continue to work, without any changes required in spite of the polyfill being removed".

I don't suggest you just hidding the stricts errors on your project. Intead, you should turn your method to static or try to creat a new instance of the object:

$var = new YourClass();
$var->method();

You can also use the new way to do the same since PHP 5.4:

(new YourClass)->method();

I hope it helps you!

The most simple way is to use find_element_by_class_name('class_name')

Following the official installation guide for Windows C++ compilers:

https://wiki.python.org/moin/WindowsCompilers

to upgrade setuptools and install specific Microsoft Visual C++ compiler.

It has already contains some points refered in other answer.

On Eric4 there is an easy way: select a block, type Ctrl+M to comment the whole block or Ctrl+alt+M to uncomment.

When this happened to me (out of nowhere) I was about to dive into the top answer above, and then I figured I'd close the project, close Visual Studio, and then re-open everything. Problem solved. VS bug?

Aren't enums best choice for these kinds of stuff?

Instead of NOW() you can use UNIX_TIMESTAMP() also:

$update_query = "UPDATE db.tablename 
                 SET insert_time=UNIX_TIMESTAMP()
                 WHERE username='$somename'";

Difference between UNIX_TIMESTAMP and NOW() in MySQL

Possible Suggestions to make it work:

Some modifications (U forgot to include a semicolon in the statement this.getName=function(){...} it should be this.getName=function(){...};)

function Customer(){
this.name="Jhon";
this.getName=function(){
return this.name;
};
}

(This might be one of the problem.)

and

Make sure U Link the JS files in the correct order

<script src="file1.js" type="text/javascript"></script>
<script src="file2.js" type="text/javascript"></script>

Don't forget to generate a second password for your Gmail account. You will use this new password in your code. Read this:

https://support.google.com/accounts/answer/185833

Under the section "How to generate an App password" click on "App passwords", then under "Select app" choose "Mail", select your device and click "Generate". Your second password will be printed on the screen.

You are using ubuntu 12 (quite old one)

First, Open the /etc/mysql/mysql.conf.d/mysqld.cnf file (/etc/mysql/my.cnf in Ubuntu 14.04 and earlier versions

Under the [mysqld] Locate the Line, bind-address = 127.0.0.1 And change it to, bind-address = 0.0.0.0 or comment it

Then, Restart the Ubuntu MysQL Server systemctl restart mysql.service

Now Ubuntu Server will allow remote access to the MySQL Server, But still you need to configure MySQL users to allow access from any host.

User must be 'username'@'%' with all the required grants

To make sure that, MySQL server listens on all interfaces, run the netstat command as follows.

netstat -tulnp | grep mysql

Hope this works !

I am using this method

$('.typeahead').typeahead({
    hint: true,
    highlight: true,
    minLength: 1
},
    {
    name: 'options',
    displayKey: 'value',
    source: function (query, process) {
        return $.get('/weather/searchCity/?q=%QUERY', { query: query }, function (data) {
            var matches = [];
            $.each(data, function(i, str) {
                matches.push({ value: str });
            });
            return process(matches);

        },'json');
    }
});

If performance is important go down to numpy level:

import numpy as np

df = pd.DataFrame({'a': np.random.randint(0, 60, 600), 'b': [1, 2, 5, 5, 4, 6]*100})

def f(df):
         keys, values = df.sort_values('a').values.T
         ukeys, index = np.unique(keys, True)
         arrays = np.split(values, index[1:])
         df2 = pd.DataFrame({'a':ukeys, 'b':[list(a) for a in arrays]})
         return df2

Tests:

In [301]: %timeit f(df)
1000 loops, best of 3: 1.64 ms per loop

In [302]: %timeit df.groupby('a')['b'].apply(list)
100 loops, best of 3: 5.26 ms per loop

for me, I do double click of ListView in this code section .

    this.listView.Activation = ItemActivation.TwoClick;

    this.listView.ItemActivate += ListView1_ItemActivate;

ItemActivate specify how user activate with items

When user do double click, ListView1_ItemActivate will be trigger. Property of ListView ItemActivate refers to access the collection of items selected.

    private void ListView1_ItemActivate(Object sender, EventArgs e)
    {

        foreach (ListViewItem item in listView.SelectedItems)
           //do something

    }

it works for me.

SQL tables have no implicit ordering, the order has to come from the data. Perhaps you should add a field to your table (e.g. an int counter) and re-import the data.

However that will only give the order of the import and not the data. If your data has no ordering you have to find out how to add it.

EDIT: you say

...to make sure it imported everything.

What's wrong with using row count?

There is no way to do this with slf4j.

I imagine that the reason that this functionality is missing is that it is next to impossible to construct a Level type for slf4j that can be efficiently mapped to the Level (or equivalent) type used in all of the possible logging implementations behind the facade. Alternatively, the designers decided that your use-case is too unusual to justify the overheads of supporting it.

Concerning @ripper234's use-case (unit testing), I think the pragmatic solution is modify the unit test(s) to hard-wire knowledge of what logging system is behind the slf4j facade ... when running the unit tests.

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

I encountered a similar problem only with a nested img in my anchor:

<a href="some/link">
   <img src="some/src">
</a>

When I applied

@media print {
   a[href]:after {
      content: none !important;
   }
}

I lost my img and the entire anchor width for some reason, so instead I used:

@media print {
   a[href]:after {
      visibility: hidden;
   }
}

which worked perfectly.

Bonus tip: inspect print preview

Since Length is an int I'd say Int.MaxValue

1. If that class from which you want to call this method, is in the same package, then create an instance of this class and call the method.

2. Use Composition

3. It would be better to have a Generic ArrayList like ArrayList<Integer> etc...

eg:

public class Test{

public ArrayList<Integer> myNumbers()    {
    ArrayList<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
 }
}


public class T{


public static void main(String[] args){

   Test t = new Test();
   ArrayList<Integer> arr = t.myNumbers();        // You can catch the returned integer arraylist into an arraylist.
 }


}

Actually - Patrick's code sort of worked for me as well. The correct way to do it would be along the lines of this:

Note: there's a bit of jquery ahead:

if ($.browser.msie == false) {
    var h = (document.getElementById("iframeID").contentDocument.body.offsetHeight);
} else {
    var h = (document.getElementById("iframeID").Document.body.scrollHeight);
}

You can use

alter table <tblname> drop column <colname>

It can be done using:-

SELECT COUNT(COLUMN_NAME) 'NO OF COLUMN' FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Address'

You aren't creating any buttons, you just have an empty list.

You can forget the list and just create the buttons in the loop.

private void button1_Click(object sender, EventArgs e) 
{     
     int top = 50;
     int left = 100;

     for (int i = 0; i < 10; i++)     
     {         
          Button button = new Button();   
          button.Left = left;
          button.Top = top;
          this.Controls.Add(button);      
          top += button.Height + 2;
     }
} 

Have you tried using JSONArray.getJSONObject(int), and JSONArray.length() to create your for-loop:

for (int i = 0; i < recs.length(); ++i) {
    JSONObject rec = recs.getJSONObject(i);
    int id = rec.getInt("id");
    String loc = rec.getString("loc");
    // ...
}

Use the ng-form directive inside of the tag in which you are using the ng-repeat directive. You can then use the scope created by the ng-form directive to reference a generic name. For example:

    <div class="form-group col-sm-6" data-ng-form="subForm" data-ng-repeat="field in justificationInfo.justifications"">

        <label for="{{field.label}}"><h3>{{field.label}}</h3></label>
        <i class="icon-valid" data-ng-show="subForm.input.$dirty && subForm.input.$valid"></i>
        <i class="icon-invalid" data-ng-show="subForm.input.$dirty && subForm.input.$invalid"></i>
        <textarea placeholder="{{field.placeholder}}" class="form-control" id="{{field.label}}" name="input" type="text" rows="3" data-ng-model="field.value" required>{{field.value}}</textarea>

    </div>

There's a much simpler decision.

@app.route('/x')
def x():
    return render_template('test.html', foo=y)

def y(text):
    return text

Then, in test.html:

{{ foo('hi') }}

By selecting 'Class Library' you were accidentally telling it to make a .Net Library using the CLI (managed) extenstion of C++.

Instead, create a Win32 project, and in the Application Settings on the next page, choose 'DLL'.

You can also make an MFC DLL or ATL DLL from those library choices if you want to go that route, but it sounds like you don't.

When you use angle brackets, the compiler searches for the file in the include path list. When you use double quotes, it first searches the current directory (i.e. the directory where the module being compiled is) and only then it'll search the include path list.

So, by convention, you use the angle brackets for standard includes and the double quotes for everything else. This ensures that in the (not recommended) case in which you have a local header with the same name as a standard header, the right one will be chosen in each case.

You can try this:

((BigDecimal) volume).intValue();

I use java.math.BigDecimal convert to int (primitive type).

It is worked for me.

Someone give Luciano these points :) I just tested his answer -had a similar question- and worked perfectly...

I even add my 50 cents:

.error(function(jqXHR, textStatus, errorThrown) {
        console.log("error " + textStatus);
        console.log("incoming Text " + jqXHR.responseText);
    })

I use both PuTTY and Bitvise SSH Client. PuTTY handles screen sessions better, but Bitvise automatically opens up a SFTP window so you can transfer files just like you would with an FTP client.

If the url is in a cell in your workbook, you can simply copy the value from that cell:

Private Sub CommandButton1_Click()
    Sheets("Sheet1").Range("A1").Copy
End Sub

(Add a button by using the developer tab. Customize the ribbon if it isn't visible.)

If the url isn't in the workbook, you can use the Windows API. The code that follows can be found here: http://support.microsoft.com/kb/210216

After you've added the API calls below, change the code behind the button to copy to the clipboard:

You can try this:

int cleft = 1;
intaleft = 1;
private void button2_Click(object sender, EventArgs e)

     TextBox txt = new TextBox();
     this.Controls.Add(txt);
     txt.Top = cleft * 40;

     cleft = cleft + 1;
     Label lbl = new Label();
     this.Controls.Add(lbl);
     lbl.Top = aleft * 40;
     lbl.Size = new Size(100, 16);
     lbl.ForeColor = Color.Blue;
     lbl.Text = "BoxNo/CardNo";
     lbl.Left = 70;

array[10] === 0 // true

I verified in firefox and chrome, its really an array of bytes :

var array = new Uint8Array(1024*1024*50);  // allocates 50MBytes

Are you using the right chat_id and including your bot's token after "bot" in the address? (api.telegram.org/bottoken/sendMessage)

This page explains a few things about sending (down in "sendMessage" section) - basic stuff, but I often forget the basics.

To quote:

In order to use the sendMessage method we need to use the proper chat_id.

First things first let's send the /start command to our bot via a Telegram client.

After sent this command let's perform a getUpdates commands.

curl -s \
-X POST \ https://api.telegram.org/bot<token>/getUpdates \ | jq .

The response will be like the following

{   "result": [
     {
       "message": {
        "text": "/start",
         "date": 1435176541,
         "chat": {
           "username": "yourusername",
           "first_name": "yourfirstname",
           "id": 65535
         },
         "from": {
           "username": "yourusername",
           "first_name": "yourfirstname",
           "id": 65535
         },
         "message_id": 1
       },
       "update_id": 714636917
     }    ],   "ok": true }

We are interested in the property result.message[0].chat.id, save this information elsewhere.

Please note that this is only an example, you may want to set up some automatism to handle those informations Now how we can send a message ? It's simple let's check out this snippet.

curl -s \
-X POST \ https://api.telegram.org/bot<token>/sendMessage \
-d text="A message from your bot" \
-d chat_id=65535 \ | jq .

Where chat_id is the piece of information saved before.

I hope that helps.

If someone is in search for a quick minimal solution,

import signal

# The code which crashes program on interruption

signal.signal(signal.SIGINT, call_this_function_if_interrupted)

# The code skipped if interrupted

If you use php-fpm, the php_admin_value will NOT work and gives an Internal Server Error.

Instead use this in your .htaccess. It disables the parser in that folder and all subfolders:

<FilesMatch ".+\.*$">
    SetHandler !
</FilesMatch>

An easy way to add buttons to Comment or Un-Comment a code block is:

• Go to View-Toolbars-Customise
• Select the Command tab
• Select the Edit Category on the left
• Drag the “Comment Block” and “Uncomment Block” icons onto your toolbar.

Alternative solution:

>>> from datetime import date
>>> (date(2012, 3, 1) - date(2012, 2, 1)).days
29

Changing this behaviour actually creates a far better user experience than the default behaviour implemented natively. Consider that the behaviour of the enter key is already inconsistent from the user's point of view, because in a single line input, enter tends to submit a form, while in a multi-line textarea, it simply adds a newline to the contents of the field.

I recently did it like this (uses jQuery):

$('input.enterastab, select.enterastab, textarea.enterastab').live('keydown', function(e) {
 if (e.keyCode==13) {
  var focusable = $('input,a,select,button,textarea').filter(':visible');
  focusable.eq(focusable.index(this)+1).focus();
  return false;
 }
});

This is not terribly efficient, but works well enough and is reliable - just add the 'enterastab' class to any input element that should behave in this way.

It is possible to change the PWD, using JNA/JNI to make calls to libc. The JRuby guys have a handy java library for making POSIX calls called jna-posix Here's the maven info

You can see an example of its use here (Clojure code, sorry). Look at the function chdirToRoot

ng-model

ng-model directive in AngularJS is one of the greatest strength to bind the variables used in application with input components. This works as two way data binding. If you want to understand better about the two way bindings, you have an input component and the value updated into that field must be reflected in other part of the application. The better solution is to bind a variable to that field and output that variable whereever you wish to display the updated value throughoput the application.

ng-bind

ng-bind works much different than ng-model. ng-bind is one way data binding used for displaying the value inside html component as inner HTML. This directive can not be used for binding with the variable but only with the HTML elements content. Infact this can be used along with ng-model to bind the component to HTML elements. This directive is very useful for updating the blocks like div, span, etc. with inner HTML content.

This example would help you to understand.

Subplot Colorbar

For subplots with scatter, you can trick a colorbar onto your axes by building the "mappable" with the help of a secondary figure and then adding it to your original plot.

As a continuation of the above example:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')


# Build your secondary mirror axes:
fig2, (ax3, ax4) = plt.subplots(1, 2)

# Build maps that parallel the color-coded data
# NOTE 1: imshow requires a 2-D array as input
# NOTE 2: You must use the same cmap tag as above for it match
map1 = ax3.imshow(np.stack([t, t]),cmap='viridis')
map2 = ax4.imshow(np.stack([t, t]),cmap='viridis_r')

# Add your maps onto your original figure/axes
fig.colorbar(map1, ax=ax1)
fig.colorbar(map2, ax=ax2)
plt.show()

Note that you will also output a secondary figure that you can ignore.

Here is a highly simplified but hopefully relevant view of what happens when you build your code in C++.

C++ splits the load of generating machine executable code in following different phases -

1. Preprocessing - This is where any macros - #defines etc you might be using get expanded.

2. Compiling - Each cpp file along with all the #included files in that file directly or indirectly (together called a compilation unit) is converted into machine readable object code.

   This is where C++ also checks that all functions defined (i.e. containing a body in { } e.g. void Foo( int x){ return Boo(x); }) are referring to other functions in a valid manner.

   The way it does that is by insisting that you provide at least a declaration of these other functions (e.g. void Boo(int); ) before you call it so it can check that you are calling it properly among other things. This can be done either directly in the cpp file where it is called or usually in an included header file.

   Note that only the machine code that corresponds to functions defined in this cpp and included files gets built as the object (binary) version of this compilation unit (e.g. Foo) and not the ones that are merely declared (e.g. Boo).

3. Linking - This is the stage where C++ goes hunting for stuff declared and called in each compilation unit and links it to the places where it is getting called. Now if there was no definition found of this function the linker gives up and errors out. Similarly if it finds multiple definitions of the same function signature (essentially the name and parameter types it takes) it also errors out as it considers it ambiguous and doesn't want to pick one arbitrarily.

The latter is what is happening in your case. By doing a #include of the fun.cpp file, both fun.cpp and mainfile.cpp have a definition of funct() and the linker doesn't know which one to use in your program and is complaining about it.

The fix as Vaughn mentioned above is to not include the cpp file with the definition of funct() in mainfile.cpp and instead move the declaration of funct() in a separate header file and include that in mainline.cpp. This way the compiler will get the declaration of funct() to work with and the linker would get just one definition of funct() from fun.cpp and will use it with confidence.

The second method, Task.Run, has been introduced in a later version of the .NET framework (in .NET 4.5).

However, the first method, Task.Factory.StartNew, gives you the opportunity to define a lot of useful things about the thread you want to create, while Task.Run doesn't provide this.

For instance, lets say that you want to create a long running task thread. If a thread of the thread pool is going to be used for this task, then this could be considered an abuse of the thread pool.

One thing you could do in order to avoid this would be to run the task in a separate thread. A newly created thread that would be dedicated to this task and would be destroyed once your task would have been completed. You cannot achieve this with the Task.Run, while you can do so with the Task.Factory.StartNew, like below:

Task.Factory.StartNew(..., TaskCreationOptions.LongRunning);

As it is stated here:

So, in the .NET Framework 4.5 Developer Preview, we’ve introduced the new Task.Run method. This in no way obsoletes Task.Factory.StartNew, but rather should simply be thought of as a quick way to use Task.Factory.StartNew without needing to specify a bunch of parameters. It’s a shortcut. In fact, Task.Run is actually implemented in terms of the same logic used for Task.Factory.StartNew, just passing in some default parameters. When you pass an Action to Task.Run:

Task.Run(someAction);

that’s exactly equivalent to:

Task.Factory.StartNew(someAction, 
    CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);

Better to use getopt facility of bash. Please look at this Q&A for more help: Using getopts in bash shell script to get long and short command line options

In Python 3.4 or newer you can use pathlib to do recursive globbing:

>>> import pathlib
>>> sorted(pathlib.Path('.').glob('**/*.py'))
[PosixPath('build/lib/pathlib.py'),
 PosixPath('docs/conf.py'),
 PosixPath('pathlib.py'),
 PosixPath('setup.py'),
 PosixPath('test_pathlib.py')]

Reference: https://docs.python.org/3/library/pathlib.html#pathlib.Path.glob

In Python 3.5 or newer you can also do recursive globbing like this:

>>> import glob
>>> glob.glob('**/*.txt', recursive=True)
['2.txt', 'sub/3.txt']

Reference: https://docs.python.org/3/library/glob.html#glob.glob

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

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

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

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

Use this example to make text box ReadOnly or Not.

<input type="textbox" class="txt" id="txt"/>
<input type="button" class="Btn_readOnly" value="Readonly" />
<input type="button" class="Btn_notreadOnly" value="Not Readonly" />

<script>

    $(document).ready(function(){
       ('.Btn_readOnly').click(function(){
           $("#txt").prop("readonly", true);
       });

       ('.Btn_notreadOnly').click(function(){
           $("#txt").prop("readonly", false);
       });
    });

</script>

I solved this problem with using the following steps:

1. File -> Import

2. Click General then select Existing Projects into Workspace

3. Click Next

4. Browse the directory of the project

5. Click Finish!

It worked for me

Most likely the socket is held by some process. Use netstat -o to find which one.

On Android the color can be declared in the following format

#AARRGGBB

AA - is the bit that’s of most interest to us, it stands for alpha channel

RR GG BB - red, green & blue channels respectively

Now in order to add transparency to our color we need to prepend it with hexadecimal value representing the alpha (transparency).

For example if you want to set 80% transparency value to black color (#000000) you need to prepend it with CC, as a result we end up with the following color resource #CC000000.

You can read about it in more detail on my blog https://androidexplained.github.io/android/ui/2020/10/12/hex-color-code-transparency.html

I had been experiencing the same problem, in my ASP.NET MVC 4 application.

The way I solved it, was in the DatabaseContext. By passing down the name of the connection string I wanted to use through the base constructor.

public class DatabaseContext : DbContext
{ 
    public DatabaseContext()
        : base("DefaultConnection") // <-- this is what i added.
    {
    }

    public DbSet<SomeModel> SomeModels { get; set; }
}

Not sure if Access supports it, but in most engines (including SQL Server) this is called a correlated subquery and works fine:

SELECT  TypesAndBread.Type, TypesAndBread.TBName,
        (
        SELECT  Count(Sandwiches.[SandwichID]) As SandwichCount
        FROM    Sandwiches
        WHERE   (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
                OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
        ) As SandwichCount
FROM    TypesAndBread

This can be made more efficient by indexing Type and Bread and distributing the subqueries over the UNION:

SELECT  [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
        )
FROM    [Sandwiches Types]
UNION ALL
SELECT  [Breads].[Bread] As TBName, "Bread" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Bread = [Breads].[Bread]
        )
FROM    [Breads]

The two syntaxes are not equivalent and it can lead to unexpected errors. Here is a simple example showing the differences. If you have a model:

from django.db import models

class Test(models.Model):

    added = models.DateTimeField(auto_now_add=True)

And you create a first object:

foo = Test.objects.create(pk=1)

Then you try to create an object with the same primary key:

foo_duplicate = Test.objects.create(pk=1)
# returns the error:
# django.db.utils.IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'")

foo_duplicate = Test(pk=1).save()
# returns the error:
# django.db.utils.IntegrityError: (1048, "Column 'added' cannot be null")

If you have even the relative pathname (in this case it appears to be ./) you can open files relative to your script file(s). I use Perl, but the same general solution can apply: I split the directory into an array of folders, then pop off the last element (the script), then push (or for you, append) on whatever I want, and then join them together again, and BAM! I have a working pathname that points to exactly where I expect it to point, relative or absolute.

Of course, there are better solutions, as posted. I just kind of like mine.

I'm one of the developers of the Tooleap SDK. We also provide a way for developers to display always on top windows and buttons, and and we have dealt with a similar situation.

One problem the answers here haven't addressed is that of the Android "Secured Buttons".

Secured buttons have the filterTouchesWhenObscured property which means they can't be interacted with, if placed under a window, even if that window does not receive any touches. Quoting the Android documentation:

Specifies whether to filter touches when the view's window is obscured by another visible window. When set to true, the view will not receive touches whenever a toast, dialog or other window appears above the view's window. Refer to the {@link android.view.View} security documentation for more details.

An example of such a button is the install button when you try to install third party apks. Any app can display such a button if adding to the view layout the following line:

android:filterTouchesWhenObscured="true"

If you display an always-on-top window over a "Secured Button", so all the secured button parts that are covered by an overlay will not handle any touches, even if that overlay is not clickable. So if you are planing to display such a window, you should provide a way for the user to move it or dismiss it. And if a part of your overlay is transparent, take into account that your user might be confused why is a certain button in the underlying app is not working for him suddenly.

Is simple:

Example:https://jsfiddle.net/RainStudios/mw786v1w/

var element = document.getElementById('element');
//create box in bottom-left
var resizer = document.createElement('div');
resizer.style.width = '10px';
resizer.style.height = '10px';
resizer.style.background = 'red';
resizer.style.position = 'absolute';
resizer.style.right = 0;
resizer.style.bottom = 0;
resizer.style.cursor = 'se-resize';
//Append Child to Element
element.appendChild(resizer);
//box function onmousemove
resizer.addEventListener('mousedown', initResize, false);

//Window funtion mousemove & mouseup
function initResize(e) {
   window.addEventListener('mousemove', Resize, false);
   window.addEventListener('mouseup', stopResize, false);
}
//resize the element
function Resize(e) {
   element.style.width = (e.clientX - element.offsetLeft) + 'px';
   element.style.height = (e.clientY - element.offsetTop) + 'px';
}
//on mouseup remove windows functions mousemove & mouseup
function stopResize(e) {
    window.removeEventListener('mousemove', Resize, false);
    window.removeEventListener('mouseup', stopResize, false);
}

You need to put the font file name / path in quotes.
Eg.

url("../fonts/Gotham-Medium.ttf")

or

url('../fonts/Gotham-Medium.ttf')

and not

url(../fonts/Gotham-Medium.ttf)

Also @FONT-FACE only works with some font files. :o(

All the sites where you can download fonts, never say which fonts work and which ones don't.

Use RxJS in a Service

Then simply subscribe to the changes.

app.controller('displayCtrl', function(DataService) {
  var $ctrl = this;

  $ctrl.data = DataService.get();
  var subscription = DataService.subscribe(function onNext(d) {
      $ctrl.data = d;
  });

  this.$onDestroy = function() {
      subscription.dispose();
  };
});

Clients can subscribe to changes with DataService.subscribe and producers can push changes with DataService.set.

If you want to draw a horizontal line in the axes, you might also try ax.hlines() method. You need to specify y position and xmin and xmax in the data coordinate (i.e, your actual data range in the x-axis). A sample code snippet is:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(1, 21, 200)
y = np.exp(-x)

fig, ax = plt.subplots()
ax.plot(x, y)
ax.hlines(y=0.2, xmin=4, xmax=20, linewidth=2, color='r')

plt.show()

The snippet above will plot a horizontal line in the axes at y=0.2. The horizontal line starts at x=4 and ends at x=20. The generated image is:

In the newer versions of Handlebars index (or key in the case of object iteration) is provided by default with the standard each helper.

snippet from : https://github.com/wycats/handlebars.js/issues/250#issuecomment-9514811

The index of the current array item has been available for some time now via @index:

{{#each array}}
    {{@index}}: {{this}}
{{/each}}

For object iteration, use @key instead:

{{#each object}}
    {{@key}}: {{this}}
{{/each}} 

If you're using fs-extra, you can skip the JSON.stringify part with the writeJson function:

const fsExtra = require('fs-extra');

fsExtra.writeJson('./package.json', {name: 'fs-extra'})
.then(() => {
  console.log('success!')
})
.catch(err => {
  console.error(err)
})

I used this method that I created when I was 14 years old.

    public static int gcd (int a, int b) {
        int s = 1;
        int ia = Math.abs(a);//<-- turns to absolute value
        int ib = Math.abs(b);
        if (a == b) {
            s = a;
        }else {
            while (ib != ia) {
                if (ib > ia) {
                    s = ib - ia;
                    ib = s;
                }else { 
                    s = ia - ib;
                    ia = s;
                }
            }
        }
        return s;
    }

transition-property:width;

This should work. you have to have browser dependent code

be An alternative for older browser could be to use mask produced by pseudo-elements or inline tags.

Absolute positionning hover an img (or text area wich needs no click nor selection) can closely mimic effects of color scale , via rgba() or translucide png .

It will not give one single color scale, but will shades color out of range.

test on code pen with 10 different colors via pseudo-element, last is gray . http://codepen.io/gcyrillus/pen/nqpDd (reload to switch to another image)

A matrix is really just a vector with a dim attribute (for the dimensions). So you can add dimensions to vec using the dim() function and vec will then be a matrix:

vec <- 1:49
dim(vec) <- c(7, 7)  ## (rows, cols)
vec

> vec <- 1:49
> dim(vec) <- c(7, 7)  ## (rows, cols)
> vec
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    1    8   15   22   29   36   43
[2,]    2    9   16   23   30   37   44
[3,]    3   10   17   24   31   38   45
[4,]    4   11   18   25   32   39   46
[5,]    5   12   19   26   33   40   47
[6,]    6   13   20   27   34   41   48
[7,]    7   14   21   28   35   42   49
