I have met same problem. In my case I had no ..\data dir in my C:\mysql\ so I just executed mysqld --initialize command from c:\mysql\bin\ directory and I got the data directory in c:\mysql\data. Afterwards I could use mysqld.exe --console command to test the server startup.

Try this for Amazon Linux AMI or for centOS

sudo service mysqld restart

The following steps are to reset the password for a user in case you forgot, this would also solve your mentioned error.

First, stop your MySQL:

sudo /etc/init.d/mysql stop

Now start up MySQL in safe mode and skip the privileges table:

sudo mysqld_safe --skip-grant-tables &

Login with root:

mysql -uroot

And assign the DB that needs to be used:

use mysql;

Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:

update user set password=PASSWORD("YOURPASSWORDHERE") where User='root';

flush privileges;

quit and restart MySQL:

quit

sudo /etc/init.d/mysql stop sudo /etc/init.d/mysql start Now your root password should be working with the one you just set, check it with:

mysql -u root -p

With the command:

sudo apt-get remove --purge mysql\*

you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).

You can list all installed mysql packages with the command:

sudo dpkg -l | grep -i mysql

For more cleanup of the package cache, you can use the command:

sudo apt-get clean

Also, remember to use the command:

sudo updatedb

Otherwise the "locate" command will display old data.

To install mysql again, use the following command:

sudo apt-get install libmysqlclient-dev mysql-client

This will install the mysql client, libmysql and its headers files.

To install the mysql server, use the command:

sudo apt-get install mysql-server

Set up the General Query Log.

it is because of letters or digit infront of [mysqld] just check the leeters or digit anything is not required before [mysqld]

it may be something like

0[mysqld] then this error will occur

From the MySQL reference manual:

By default, all log files are created in the data directory.

Check /var/lib/mysql folder.

I was having trouble on a database restore using mysqldumper (php program). I was able to get it working by changing the "mssql.timeout" setting in the php.ini. It was defaulted to 60 and I changed it to 300.

Here is an alternative programming solution that may work for others who use MyISAM IF (important) you don't care if an update has happened during the middle of the queries. As we know MyISAM can cause table level locks, especially if you have an update pending which will get locked, and then other select queries behind this update get locked too.

So this method won't prevent a lock, but it will make a lot of tiny locks, so as not to hang a website for example which needs a response within a very short frame of time.

The idea here is we grab a range based on an index which is quick, then we do our match from that query only, so it's in smaller batches. Then we move down the list onto the next range and check them for our match.

Example is in Perl with a bit of pseudo code, and traverses high to low.

# object_id must be an index so it's fast
# First get the range of object_id, as it may not start from 0 to reduce empty queries later on.

my ( $first_id, $last_id ) = $db->db_query_array(
  sql => q{ SELECT MIN(object_id), MAX(object_id) FROM mytable }
);

my $keep_running = 1;
my $step_size    = 1000;
my $next_id      = $last_id;

while( $keep_running ) {

    my $sql = q{ 
SELECT object_id, created, status FROM 
    ( SELECT object_id, created, status FROM mytable AS is1 WHERE is1.object_id <= ? ORDER BY is1.object_id DESC LIMIT ? ) AS is2
WHERE status='live' ORDER BY object_id DESC 
};  

    my $sth = $db->db_query( sql => $sql, args => [ $step_size, $next_id ] );

    while( my ($object_id, $created, $status ) = $sth->fetchrow_array() ) {

        $last_id = $object_id;
        
        ## do your stuff

    }

    if( !$last_id ) {
        $next_id -= $step_size; # There weren't any matched in the range we grabbed
    } else {
        $next_id = $last_id - 1; # There were some, so we'll start from that.
    }

    $keep_running = 0 if $next_id < 1 || $next_id < $first_id;
    
}

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

There is a new configuration section that is used to reference namespaces for Razor views.

Open the web.config file in your Views folder, and make sure it has the following:

<configuration>
    <configSections>
        <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
            <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
            <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
        </sectionGroup>
    </configSections>

    <system.web.webPages.razor>
        <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        <pages pageBaseType="System.Web.Mvc.WebViewPage">
            <namespaces>
                <add namespace="System.Web.Mvc" />
                <add namespace="System.Web.Mvc.Ajax" />
                <add namespace="System.Web.Mvc.Html" />
                <add namespace="System.Web.Routing" />
                <add namespace="SquishIt.Framework" />
                <add namespace="Your.Namespace.Etc" />
            </namespaces>
        </pages>
    </system.web.webPages.razor>
</configuration>

Alternatively, you can add using statements to your shared layout:

@using Your.Namespace.Etc;
<!DOCTYPE html>
<head>
....

After editing the Web.config, restart Visual Studio to apply the changes.

Inf is infinity, it's a "bigger than all the other numbers" number. Try subtracting anything you want from it, it doesn't get any smaller. All numbers are < Inf. -Inf is similar, but smaller than everything.

NaN means not-a-number. If you try to do a computation that just doesn't make sense, you get NaN. Inf - Inf is one such computation. Usually NaN is used to just mean that some data is missing.

From Java documentation

If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes — you will learn about them in a later lesson.)

At the member level, you can also use the public modifier or no modifier (package-private) just as with top-level classes, and with the same meaning.

Full story you can read here (_{Which I wrote recently}):

http://codeinventions.blogspot.com/2014/09/default-access-modifier-in-java-or-no.html

1.Go to your manifest.xml file.

2.Find the activity tag for which you want to hide your ActionBar and then add ,

android:theme="@style/Theme.AppCompat.NoActionBar"

           <activity
            android:name=".MainActivity"
            android:theme="@style/Theme.AppCompat.NoActionBar"
            >

Change ng-disabled="!contractTypeValid" to [disabled]="!contractTypeValid"

It is not legal to declare an instance member in a static class. Static class's cannot be instantiated hence it makes no sense to have an instance members (they'd never be accessible).

I wanted to ask the same question. Here is my current solution to obtain a string like this: 2013-02-07 09:24:40.749355372 I am not sure if there is a more straight forward solution than this, but at least the string format is freely configurable with this approach.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>

#define NANO 1000000000L

// buf needs to store 30 characters
int timespec2str(char *buf, uint len, struct timespec *ts) {
    int ret;
    struct tm t;

    tzset();
    if (localtime_r(&(ts->tv_sec), &t) == NULL)
        return 1;

    ret = strftime(buf, len, "%F %T", &t);
    if (ret == 0)
        return 2;
    len -= ret - 1;

    ret = snprintf(&buf[strlen(buf)], len, ".%09ld", ts->tv_nsec);
    if (ret >= len)
        return 3;

    return 0;
}

int main(int argc, char **argv) {
    clockid_t clk_id = CLOCK_REALTIME;
    const uint TIME_FMT = strlen("2012-12-31 12:59:59.123456789") + 1;
    char timestr[TIME_FMT];

    struct timespec ts, res;
    clock_getres(clk_id, &res);
    clock_gettime(clk_id, &ts);

    if (timespec2str(timestr, sizeof(timestr), &ts) != 0) {
        printf("timespec2str failed!\n");
        return EXIT_FAILURE;
    } else {
        unsigned long resol = res.tv_sec * NANO + res.tv_nsec;
        printf("CLOCK_REALTIME: res=%ld ns, time=%s\n", resol, timestr);
        return EXIT_SUCCESS;
    }
}

output:

I had a scenario where nested JSON had to be serialised in a linear fashion while form data is constructed, since this is how server expects values. So, I wrote a small recursive function which translates the JSON which is like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress":{
      "city":"Wonderland",
      "code":"8796682911767",
      "firstname":"Raj Pawan",
      "lastname":"Gumdal",
      "line1":"Addr Line 1",
      "line2":null,
      "state":"US-AS",
      "region":{
         "isocode":"US-AS"
      },
      "zip":"76767-6776"
   }
}

Into something like this:

{
   "orderPrice":"11",
   "cardNumber":"************1234",
   "id":"8796191359018",
   "accountHolderName":"Raj Pawan",
   "expiryMonth":"02",
   "expiryYear":"2019",
   "issueNumber":null,
   "billingAddress.city":"Wonderland",
   "billingAddress.code":"8796682911767",
   "billingAddress.firstname":"Raj Pawan",
   "billingAddress.lastname":"Gumdal",
   "billingAddress.line1":"Addr Line 1",
   "billingAddress.line2":null,
   "billingAddress.state":"US-AS",
   "billingAddress.region.isocode":"US-AS",
   "billingAddress.zip":"76767-6776"
}

The server would accept form data which is in this converted format.

Here is the function:

function jsonToFormData (inJSON, inTestJSON, inFormData, parentKey) {
    // http://stackoverflow.com/a/22783314/260665
    // Raj: Converts any nested JSON to formData.
    var form_data = inFormData || new FormData();
    var testJSON = inTestJSON || {};
    for ( var key in inJSON ) {
        // 1. If it is a recursion, then key has to be constructed like "parent.child" where parent JSON contains a child JSON
        // 2. Perform append data only if the value for key is not a JSON, recurse otherwise!
        var constructedKey = key;
        if (parentKey) {
            constructedKey = parentKey + "." + key;
        }

        var value = inJSON[key];
        if (value && value.constructor === {}.constructor) {
            // This is a JSON, we now need to recurse!
            jsonToFormData (value, testJSON, form_data, constructedKey);
        } else {
            form_data.append(constructedKey, inJSON[key]);
            testJSON[constructedKey] = inJSON[key];
        }
    }
    return form_data;
}

Invocation:

        var testJSON = {};
        var form_data = jsonToFormData (jsonForPost, testJSON);

I am using testJSON just to see the converted results since I would not be able to extract the contents of form_data. AJAX post call:

        $.ajax({
            type: "POST",
            url: somePostURL,
            data: form_data,
            processData : false,
            contentType : false,
            success: function (data) {
            },
            error: function (e) {
            }
        });

Actually, as far as I know, nginx would show an empty message and it wouldn't actually restart if the configuration is bad.

The only way to screw it up is by doing an nginx stop and then start again. It would succeed to stop, but fail to start.

From version 3.7 you can use time.time_ns() to get time as passed nano seconds from epoch. So you can do

ms = time.time_ns() // 1_000_000 

to get time in mili-seconds as integer.

I have implemented this using web view. In my case i have to load image from URL along with the text in text view and this works for me.

WebView myWebView =new WebView(_context);
        String html = childText;
        String mime = "text/html";
        String encoding = "utf-8";
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.loadDataWithBaseURL(null, html, mime, encoding, null);

Your question is not very clear.

• What's your code exactly doing? Give more code.
• What's the error you're getting?

You say you get a null-pointer. You cannot get a null pointer as a value returned by contains().

However you can get a NullPointerException if your list has not been initialized. By reading your question now, I'd say that what you show here is correct, but maybe you just didn't instantiate the list.

For this to work (to add a feed URL if it isn't already in the list):

if (!this.rssFeedURLs.contains(rssFeedURL)) {
    this.rssFeedURLs.add(rssFeedUrl);
}

then this declaration would do:

private ArrayList<String> rssFeedURLs = new ArrayList<String>();

or initialize your list later on, but before trying to access its methods:

rssFeedUrls = new ArrayList<String>();

Finally... Do you really need a List? Maybe a Set would be better if you don't want duplicates. Use a LinkedHashSet if preserving the ordering matters.

If you use jquery, it can be done by using $(window).height();

<iframe src="html_intro.asp" width="100%" class="myIframe">
<p>Hi SOF</p>
</iframe>

<script type="text/javascript" language="javascript"> 
$('.myIframe').css('height', $(window).height()+'px');
</script>

I know the question asked about "write" but in a more general sense "append" might be useful in some cases as it is easy to use in a loop to add text to a file (whether the file exists or not). Use a "\n" if you want to add lines eg:

var fs = require('fs');
for (var i=0; i<10; i++){
    fs.appendFileSync("junk.csv", "Line:"+i+"\n");
}

echo `date +%s`/86400 | bc

<ProgressBar  
android:minHeight="20dip" 
android:maxHeight="20dip"/>

The answer I was looking for is at https://unix.stackexchange.com/a/9557/114862.

Using the -c flag when the local file is of greater or equal size to the server version will avoid re-downloading.

alter table table_name add field_name (size);

alter table arnicsc add place number(10);

try

<button onclick="window.location.href='b.php'">Click me</button>

e.printStackTrace equivalent in python

In Java, this does the following (docs):

public void printStackTrace()

Prints this throwable and its backtrace to the standard error stream...

This is used like this:

try
{ 
// code that may raise an error
}
catch (IOException e)
{
// exception handling
e.printStackTrace();
}

In Java, the Standard Error stream is unbuffered so that output arrives immediately.

The same semantics in Python 2 are:

import traceback
import sys
try: # code that may raise an error
    pass 
except IOError as e: # exception handling
    # in Python 2, stderr is also unbuffered
    print >> sys.stderr, traceback.format_exc()
    # in Python 2, you can also from __future__ import print_function
    print(traceback.format_exc(), file=sys.stderr)
    # or as the top answer here demonstrates, use:
    traceback.print_exc()
    # which also uses stderr.

Python 3

In Python 3, we can get the traceback directly from the exception object (which likely behaves better for threaded code). Also, stderr is line-buffered, but the print function gets a flush argument, so this would be immediately printed to stderr:

    print(traceback.format_exception(None, # <- type(e) by docs, but ignored 
                                     e, e.__traceback__),
          file=sys.stderr, flush=True)

Conclusion:

In Python 3, therefore, traceback.print_exc(), although it uses sys.stderr by default, would buffer the output, and you may possibly lose it. So to get as equivalent semantics as possible, in Python 3, use print with flush=True.

Each application pool in IIs creates its own secure user folder with FULL read/write permission by default under c:\users. Open up your Users folder and see what application pool folders are there, right click, and check their rights for the application pool virtual account assigned. You should see your application pool account added already with read/write access assigned to its root and subfolders.

So that type of file storage access is automatically done and you should be able to write whatever you like there in the app pools user account folders without changing anything. That's why virtual user accounts for each application pool were created.

I ran into a very similar situation as you. Most of the searches I came across stated all I needed to do was set the Owner of the windows I wish to be Topmost to the main window or whatever window that called Show.

Anyways, I'll go ahead and post a solution that worked well for me.

I created event handlers for Window.Activated and Window.Deactived in the window that was supposed to be Topmost with respect to my application.

private void Window_Activated(object sender, EventArgs e)
{
    Topmost = true;
}

private void Window_Deactived(object sender, EventArgs e)
{
    if(Owner == null || Owner.IsActive)
        return;
    bool hasActiveWindow = false;
    foreach(Window ownedWindow in Owner.OwnedWindows)
    {
        if(ownedWindow.IsActive)
            hasActiveWindow = true; 
    }

    if(!hasActiveWindow)
        Topmost = false;
}

It works great for me. Hopefully this is useful to someone else out there. :o)

On Windows you can use cmd echo "" >.gitignore

Or use Git Bash cmd touch .gitignore, this useful for Linux and Mac System

Additionnally to hotkey's good answer, here is how I choose among the two in practice:

lateinit is for external initialisation: when you need external stuff to initialise your value by calling a method.

e.g. by calling:

private lateinit var value: MyClass

fun init(externalProperties: Any) {
   value = somethingThatDependsOn(externalProperties)
}

While lazy is when it only uses dependencies internal to your object.

If you're trying to find an element by id, you don't need to search the table only - it should be unique on the page, and so you should be able to use:

var verificaHorario = $('#' + horaInicial);

If you need to search only in the table for whatever reason, you can use:

var verificaHorario = $("#tbIntervalos").find("td#" + horaInicial)

I figured it out. You just have to use some special selectors.

The problem with rounding the corners of the table was that the td elements didn't also become rounded. You can solve that by doing something like this:

table tr:last-child td:first-child {
    border-bottom-left-radius: 10px;
}

table tr:last-child td:last-child {
    border-bottom-right-radius: 10px;
}

Now everything rounds properly, except that there's still the issue of border-collapse: collapse breaking everything.

A workaround is to add border-spacing: 0 and leave the default border-collapse: separate on the table.

Enable allow_url_fopen From cPanel Or WHM in PHP INI Section

I found a better way of doing it so you can get a input from a txtbox or have something be generated in that text box and be able to click a button to do it.!

import java.awt.datatransfer.*;
import java.awt.Toolkit;

private void /* Action performed when the copy to clipboard button is clicked */ {
    String ctc = txtCommand.getText().toString();
    StringSelection stringSelection = new StringSelection(ctc);
    Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
    clpbrd.setContents(stringSelection, null);
}

// txtCommand is the variable of a text box

import time

int(time.time()) 

Output:

This is late to the game, but I built this recursive caster. It works for my needs and I think it's relatively complete. It may help you.

def _parseJSON(self, obj):
    newobj = {}

    for key, value in obj.iteritems():
        key = str(key)

        if isinstance(value, dict):
            newobj[key] = self._parseJSON(value)
        elif isinstance(value, list):
            if key not in newobj:
                newobj[key] = []
                for i in value:
                    newobj[key].append(self._parseJSON(i))
        elif isinstance(value, unicode):
            val = str(value)
            if val.isdigit():
                val = int(val)
            else:
                try:
                    val = float(val)
                except ValueError:
                    val = str(val)
            newobj[key] = val

    return newobj

Just pass it a JSON object like so:

obj = json.loads(content, parse_float=float, parse_int=int)
obj = _parseJSON(obj)

I have it as a private member of a class, but you can repurpose the method as you see fit.

In this particular example I think @Tagir is 100% correct get it into one filter and do the two checks. I wouldn't use Optional.ofNullable the Optional stuff is really for return types not to be doing logic... but really neither here nor there.

I wanted to point out that java.util.Objects has a nice method for this in a broad case, so you can do this:

cars.stream()
    .filter(Objects::nonNull)

Which will clear out your null objects. For anyone not familiar, that's the short-hand for the following:

cars.stream()
    .filter(car -> Objects.nonNull(car))

To partially answer the question at hand to return the list of car names that starts with "M":

cars.stream()
    .filter(car -> Objects.nonNull(car))
    .map(car -> car.getName())
    .filter(carName -> Objects.nonNull(carName))
    .filter(carName -> carName.startsWith("M"))
    .collect(Collectors.toList());

Once you get used to the shorthand lambdas you could also do this:

cars.stream()
    .filter(Objects::nonNull)
    .map(Car::getName)        // Assume the class name for car is Car
    .filter(Objects::nonNull)
    .filter(carName -> carName.startsWith("M"))
    .collect(Collectors.toList());

Unfortunately once you .map(Car::getName) you'll only be returning the list of names, not the cars. So less beautiful but fully answers the question:

cars.stream()
    .filter(car -> Objects.nonNull(car))
    .filter(car -> Objects.nonNull(car.getName()))
    .filter(car -> car.getName().startsWith("M"))
    .collect(Collectors.toList());

The returned data is the binary data of the image type. If you use JavaScript to retrieve the user photo, please get the photo data as blob type in a XMLHttpRequest, and then retrieve the blob URL from the response. For your reference:

 var request = new XMLHttpRequest;
 var photoUri=config.endpoints.graphApiUri + "/v1.0/me/photo/$value";
 request.open("GET",photoUri);
 request.setRequestHeader("Authorization","Bearer "+token);
 request.responseType = "blob";
 request.onload = function (){
        if(request.readyState == 4 && request.status == 200){
               var image = document.createElement("img");
               var url = window.URL || window.webkitURL;
               var blobUrl = url.createObjectURL(request.response);
               image.src = blobUrl;
               document.getElementById("UserShow").appendChild(image);
        }
 };
 request.send(null); 

You could also look with a

netstat -abn

It gives the ports with the corresponding application that keeps them open.

Edit: or TCPView.

I got this error message when sending data from a html form (Post method). All I had to do was change the encoding in the form from "text/plain" to "application/x-www-form-urlencoded" or "multipart/form-data". The error message was very misleading.

Assuming you have a form like this:

<form id="myForm" action="foo.php" method="post">
   <input type="text" value="" />
   <input type="submit" value="submit form" />

</form>

You can attach a onsubmit-event with jQuery like this:

$('#myForm').submit(function() {
  alert('Handler for .submit() called.');
  return false;
});

If you return false the form won't be submitted after the function, if you return true or nothing it will submit as usual.

See the jQuery documentation for more info.

Use [^A-Za-z0-9].

Note: removed the space since that is not typically considered alphanumeric.

remove the margin for the h4 tag

h4 {
margin:0px;
}

Yes, it is possible by using a simple custom pipe. Advantage of using custom pipe is if we need to update the date format in future, we can go and update a single file.

import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';

@Pipe({
    name: 'dateFormatPipe',
})
export class dateFormatPipe implements PipeTransform {
    transform(value: string) {
       var datePipe = new DatePipe("en-US");
        value = datePipe.transform(value, 'MMM-dd-yyyy');
        return value;
    }
}

{{currentDate | dateFormatPipe }}

You can always use this pipe anywhere , component, services etc

For example:

export class AppComponent {
  currentDate : any;
  newDate : any;
  constructor(){
    this.currentDate = new Date().getTime();
    let dateFormatPipeFilter = new dateFormatPipe();
    this.newDate = dateFormatPipeFilter.transform(this.currentDate);
    console.log(this.newDate);
}

Don't forget to import dependencies.

import { Component } from '@angular/core';
import {dateFormatPipe} from './pipes'

Hope you dont mind Xml.Linq and .net3.5+

XElement ele = XElement.Load("text.xml");
String aXmlString = ele.toString(SaveOptions.DisableFormatting);

Depending on what you are interested in, you can probably skip the whole 'string' var part and just use XLinq objects

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

SQL Fiddle Demo with both

Simply have them in the same controller, and do something like this:

HTML:

<input id="upload"
    type="file"
    ng-file-select="onFileSelect($files)"
    style="display: none;">

<button type="button"
    ng-click="startUpload()">Upload</button>

JS:

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.files = [];
  $scope.startUpload = function(){
    for (var i = 0; i < $scope.files.length; i++) {
      $upload($scope.files[i]);
    } 
  }
  $scope.onFileSelect = function($files) {
     $scope.files = $files;
  };
}];

This is, in my opinion, the best way to do it in angular. Using jQuery to find the element and trigger an event isn't the best practice.

#include <iostream>
#include <iomanip>
#include <sstream>

int main()
{
    int x, y;
    std::stringstream stream;

    std::cin >> x;
    stream << x;
    stream >> std::hex >> y;
    std::cout << y;

    return 0;
}

var otherInput = $(this).closest('.row').find('.inputQty');

That goes up to a row level, then back down to .inputQty.

your fadeIn() function calls the fadeOut() function, which calls the fadeIn() function again. the recursion is in the JS.

Since 2005, Mozilla browsers such as Firefox have supported the non-standard :-moz-broken CSS pseudo-class that can accomplish exactly this request:

td {_x000D_
  min-width:64px; /* for display purposes so you can see the empty cell */_x000D_
}_x000D_
_x000D_
img[alt]:-moz-broken {_x000D_
  display:none;_x000D_
}

<table border="1"><tr><td>_x000D_
  <img src="error">_x000D_
</td><td>_x000D_
  <img src="broken" alt="A broken image">_x000D_
</td><td>_x000D_
  <img src="https://images-na.ssl-images-amazon.com/images/I/218eLEn0fuL.png"_x000D_
       alt="A bird" style="width: 120px">_x000D_
</td></tr></table>

img[alt]::before also works in Firefox 64 (though once upon a time it was img[alt]::after so this is not reliable). I can't get either of those to work in Chrome 71.

System.out.print("\"Hello\"");

The double quote character has to be escaped with a backslash in a Java string literal. Other characters that need special treatment include:

• Carriage return and newline: "\r" and "\n"
• Backslash: "\\\\"
• Single quote: "\'"
• Horizontal tab and form feed: "\t" and "\f"

The complete list of Java string and character literal escapes may be found in the section 3.10.6 of the JLS.

It is also worth noting that you can include arbitrary Unicode characters in your source code using Unicode escape sequences of the form "\uxxxx" where the "x"s are hexadecimal digits. However, these are different from ordinary string and character escapes in that you can use them anywhere in a Java program ... not just in string and character literals; see JLS sections 3.1, 3.2 and 3.3 for a details on the use of Unicode in Java source code.

Python's standard library has json and urllib2 modules.

import json
import urllib2

data = json.load(urllib2.urlopen('http://someurl/path/to/json'))

You can't predefine a size of an array in php. A good way to acheive your goal is the following:

// Create a new array.
$array = array(); 

// Add an item while $i < yourWantedItemQuantity
for ($i = 0; $i < $number_of_items; $i++)
{
    array_push($array, $some_data);
    //or $array[] = $some_data; for single items.
}

Note that it is way faster to use array_fill() to fill an Array :

$array = array_fill(0,$number_of_items, $some_data);

If you want to verify if a value has been set at an index, you should use the following: array_key_exists("key", $array) or isset($array["key"])

See array_key_exists , isset and array_fill

The name of CA file to use you could pass via verify:

cafile = 'cacert.pem' # http://curl.haxx.se/ca/cacert.pem
r = requests.get(url, verify=cafile)

If you use verify=True then requests uses its own CA set that might not have CA that signed your server certificate.

Very simple way to do this---

In your Activity--

 TextView tv = (TextView) findViewById(R.id.site);
 tv.setText(Html.fromHtml("<a href=http://www.stackoverflow.com> STACK OVERFLOW "));
 tv.setMovementMethod(LinkMovementMethod.getInstance());

Then you will get just the Tag, not the whole link..

Hope it will help you...

There really is no difference from a performance and code generated standpoint. In performance testing, they went back and forth between which one was faster vs the other, and only by milliseconds.

In looking at the behind the scenes code, you really don't see any difference either. The only difference is in the IL, which string.Empty use the opcode ldsfld and "" uses the opcode ldstr, but that is only because string.Empty is static, and both instructions do the same thing. If you look at the assembly that is produced, it is exactly the same.

C# Code

private void Test1()
{
    string test1 = string.Empty;    
    string test11 = test1;
}

private void Test2()
{
    string test2 = "";    
    string test22 = test2;
}

          Test1() cil managed
{
  // Code size       10 (0xa)
  .maxstack  1
  .locals init ([0] string test1,
                [1] string test11)
  IL_0000:  nop
  IL_0001:  ldsfld     string [mscorlib]System.String::Empty

  IL_0008:  stloc.1
  IL_0009:  ret
} // end of method Form1::Test1

.method private hidebysig instance void 
        Test2() cil managed

  // Code size       10 (0xa)
  .maxstack  1
  .locals init ([0] string test2,
                [1] string test22)

  IL_0007:  ldloc.0
  IL_0008:  stloc.1
  IL_0009:  ret
} // end of method Form1::Test2

You could also sidestep nested cursor issues, general cursor issues, and global variable issues by avoiding the cursors entirely.

declare @rowid int
declare @rowid2 int
declare @id int
declare @type varchar(10)
declare @rows int
declare @rows2 int
declare @outer table (rowid int identity(1,1), id int, type varchar(100))
declare @inner table (rowid int  identity(1,1), clientid int, whatever int)

insert into @outer (id, type) 
Select id, type from sometable

select @rows = count(1) from @outer
while (@rows > 0)
Begin
    select top 1 @rowid = rowid, @id  = id, @type = type
    from @outer
    insert into @innner (clientid, whatever ) 
    select clientid whatever from contacts where contactid = @id
    select @rows2 = count(1) from @inner
    while (@rows2 > 0)
    Begin
        select top 1 /* stuff you want into some variables */
        /* Other statements you want to execute */
        delete from @inner where rowid = @rowid2
        select @rows2 = count(1) from @inner
    End  
    delete from @outer where rowid = @rowid
    select @rows = count(1) from @outer
End

In Windows 7 I didn't have to restart, simply run command prompt in administrator mode.

You can use IP Webcam, or perhaps use DLNA. For example Samsung devices come with an app called AllShare which can share and access DLNA enabled devices on the network. I think IP Webcam is your best bet, though. You should be able to open the stream it creates using MX Video player or something like that.

In order to fully avoid floating point issues, the amount whose percent is being calculated and the percent itself need to be converted to integers. Here's how I resolved this:

function calculatePercent(amount, percent) {
    const amountDecimals = getNumberOfDecimals(amount);
    const percentDecimals = getNumberOfDecimals(percent);
    const amountAsInteger = Math.round(amount + `e${amountDecimals}`);
    const percentAsInteger = Math.round(percent + `e${percentDecimals}`);
    const precisionCorrection = `e-${amountDecimals + percentDecimals + 2}`;    // add 2 to scale by an additional 100 since the percentage supplied is 100x the actual multiple (e.g. 35.8% is passed as 35.8, but as a proper multiple is 0.358)

    return Number((amountAsInteger * percentAsInteger) + precisionCorrection);
}

function getNumberOfDecimals(number) {
    const decimals = parseFloat(number).toString().split('.')[1];

    if (decimals) {
        return decimals.length;
    }

    return 0;
}

calculatePercent(20.05, 10); // 2.005

As you can see, I:

1. Count the number of decimals in both the amount and the percent
2. Convert both amount and percent to integers using exponential notation
3. Calculate the exponential notation needed to determine the proper end value
4. Calculate the end value

The usage of exponential notation was inspired by Jack Moore's blog post. I'm sure my syntax could be shorter, but I wanted to be as explicit as possible in my usage of variable names and explaining each step.

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

The rowSums function (as Greg mentions) will do what you want, but you are mixing subsetting techniques in your answer, do not use "$" when using "[]", your code should look something more like:

data$new <- rowSums( data[,43:167] )

If you want to use a function other than sum, then look at ?apply for applying general functions accross rows or columns.

If you have a ConstraintLayout with some size, and a child View with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"

or

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

Because the view is smaller, these constraints are impossible. But ConstraintLayout will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.

This concept works with any target view, not just the parent.

You might want to check out RFC 6570. This URI Template spec shows many examples of how urls can contain parameters.

You can use a function comparator without wrapping it like so:

bool comparator(const MyType &lhs, const MyType &rhs)
{
    return [...];
}

std::set<MyType, bool(*)(const MyType&, const MyType&)> mySet(&comparator);

which is irritating to type out every time you need a set of that type, and can cause issues if you don't create all sets with the same comparator.

In your specific case,

String cardString = "";
for (PlayingCard c : this.list)  // <--
{
    cardString = cardString + c + "\n";
}

this.list is a collection (list, set, or array), and that code assigns c to each element of the collection.

So, if this.list were a collection {"2S", "3H", "4S"} then the cardString on the end would be this string:

2S
3H
4S

It's quite simple, first HTML must be added:

<div id="dialog"></div>

Then, it must be initialized:

<script type="text/javascript">
  jQuery( document ).ready( function() {
    jQuery( '#dialog' ).dialog( { 'autoOpen': false } );
  });
</script>

After this you can show it by code:

jQuery( '#dialog' ).dialog( 'open' );

If you are using c# 3.0 (or above) you can use extenders

Call myTextInputLayout.setError() instead of myEditText.setError().

These container and containment have double functionality on setting errors. Functionality you need is container's one. But you could require minimal version of 23 for that.

int index= datagridview.rows.add();
datagridview.rows[index].cells[1].value=1;
datagridview.rows[index].cells[2].value="a";
datagridview.rows[index].cells[3].value="b";

hope this help! :)

Try /public_html/stats/* ?

But since the files in git status reported as to be commited that means you've already added them manually. In which case, of course, it's a bit too late to ignore. You can git rm --cache them (IIRC).

Passing arbitrary arguments:

a = override(a, function(original_a) {
    if (condition) { new_code(); original_a.apply(this, arguments) ; }
    else { original_a.apply(this, arguments); other_new_code(); }
});

output

I just wasted my time on this and wanted to add an additional case where this error presents itself.

SQL Error (1292): Truncated incorrect DOUBLE value: 'N0003'

Test data

CREATE TABLE `table1 ` (
    `value1` VARCHAR(50) NOT NULL 
);
INSERT INTO table1 (value1) VALUES ('N0003');

CREATE TABLE `table2 ` (
    `value2` VARCHAR(50) NOT NULL 
);

INSERT INTO table2 (value2)
SELECT value1
FROM table1
WHERE 1
ORDER BY value1+0

The problem is ORDER BY value1+0 - type casting.

I know that it does not answer the question but this is the first result on Google for this error and it should have other examples where this error presents itself.

String.format("Hello %s Please find attached %s which is due on %s", name, invoice, date)

Instead of using FileWriter, create a FileOutputStream. You can then wrap this in an OutputStreamWriter, which allows you to pass an encoding in the constructor. Then you can write your data to that inside a try-with-resources Statement:

try (OutputStreamWriter writer =
             new OutputStreamWriter(new FileOutputStream(PROPERTIES_FILE), StandardCharsets.UTF_8))
    // do stuff
}

Apart from using the importlib one can also use exec method to import a module from a string variable.

Here I am showing an example of importing the combinations method from itertools package using the exec method:

MODULES = [
    ['itertools','combinations'],
]

for ITEM in MODULES:
    import_str = "from {0} import {1}".format(ITEM[0],', '.join(str(i) for i in ITEM[1:]))
    exec(import_str)

ar = list(combinations([1, 2, 3, 4], 2))
for elements in ar:
    print(elements)

Output:

(1, 2)
(1, 3)
(1, 4)
(2, 3)
(2, 4)
(3, 4)

React child(singular) should be type of primitive data type not object or it could be JSX tag(which is not in our case). Use Proptypes package in development to make sure validation happens.

Just a quick code snippet(JSX) comparision to represent you with idea :

1. Error : With object being passed into child

   <div>
   {/* item is object with user's name and its other details on it */}
    {items.map((item, index) => {
     return <div key={index}>
   --item object invalid as react child--->>>{item}</div>;
    })}
   </div>
   

2. Without error : With object's property(which should be primitive, i.e. a string value or integer value) being passed into child.

   <div>
    {/* item is object with user's name and its other details on it */}
     {items.map((item, index) => {
      return <div key={index}>
   --note the name property is primitive--->{item.name}</div>;
     })}
   </div>
   

TLDR; (From the source below) : Make sure all of the items you're rendering in JSX are primitives and not objects when using React. This error usually happens because a function involved in dispatching an event has been given an unexpected object type (i.e passing an object when you should be passing a string) or part of the JSX in your component is not referencing a primitive (i.e. this.props vs this.props.name).

There are quite a few ways to work with dynamic arrays in PHP. Initialise an array:

$array = array();

Add to an array:

$array[] = "item"; // for your $arr1 
$array[$key] = "item"; // for your $arr2
array_push($array, "item", "another item");

Remove from an array:

$item = array_pop($array);
$item = array_shift($array);
unset($array[$key]);

There are plenty more ways, these are just some examples.

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

This exact functionality (3 second glow to highlight a message) is implemented in the jQuery UI as the highlight effect

https://api.jqueryui.com/highlight-effect/

Color and duration are variable

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.

As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..

    public string DisplayedImagePath
    {
        get { return @"~\..\images\osc.png"; }
    }

This was tested, see below my Solution Explorer in VS2015..

)

Note: if you want a Click event, use the Button tag around the image,

<Button Click="image_Click" Width="128" Height="128"  Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
  <Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

If you're looking for a ruby based solution for this problem, I recommend using the Google Calculator method a solution similar to the following: http://j.mp/QIC564

require 'faraday'
require 'faraday_middleware'
require 'json'

# Debug: 
# require "pry"


country_code_src = "USD"
country_code_dst = "INR"
connection = Faraday.get("http://www.google.com/ig/calculator?hl=en&q=1#{country_code_src}=?#{country_code_dst}")

currency_comparison_hash = eval connection.body #Google's output is not JSON, it's a hash

dst_currency_value, *dst_currency_text = *currency_comparison_hash[:rhs].split(' ')
dst_currency_value = dst_currency_value.to_f
dst_currency_text = dst_currency_text.join(' ')

puts "#{country_code_dst} -> #{dst_currency_value} (#{dst_currency_text} to 1 #{country_code_src})"

I hope it will help someone ! (works on Angular 6)

I had to add lots of select/options dynamically and following worked for me:

<div *ngFor="let option of model.q_options; let ind=index;">

        <select 
          [(ngModel)]="model.q_options[ind].type" 
          [ngModelOptions]="{standalone: true}"
        > 
          <option 
            *ngFor="let object of objects" 
            [ngValue]="object.type" 
            [selected]="object.type === model.q_options[ind].type"
          >{{object.name}}
          </option>
        </select> 

        <div [ngSwitch]="model.q_options[ind].type">
          ( here <div *ngSwitchCase="'text' or 'imagelocal' or etc."> is used to add specific input forms )
        </div>
</div>

and in *.ts

// initial state of the model
// q_options in html = NewOption and its second argument is option type
model = new NewQuestion(1, null, 2, 
  [
    new NewOption(0, 'text', '', 1), 
    new NewOption(1, 'imagelocal', '', 1)
  ]);

// dropdown options
objects = [
    {type: 'text', name: 'text'},
    {type: 'imagelocal', name: 'image - local file'},
    {type: 'imageurl', name: 'image URL'}
   ( and etc.)
];

When user adds one more 'input option' (pls do not confuse 'input option' with select/options - select/options are static here) specific select/option, selected by the user earlier, is preserved on each/all dynamically added 'input option's select/options.

You don't have to add file.py.

Just keep the file in the same location with the file from where you want to import it. Then just import your functions:

from file import a, b

Define "First"? If the table has a PK then it will be ordered by that, and you can delete by that:

DECLARE @TABLE TABLE
(
    ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
    Data NVARCHAR(50) NOT NULL
)

INSERT INTO @TABLE(Data)
SELECT 'Hello' UNION
SELECT 'World' 

SET ROWCOUNT 1
DELETE FROM @TABLE
SET ROWCOUNT 0

SELECT * FROM @TABLE

If the table has no PK, then ordering won't be guaranteed...

CREATE PROCEDURE dbo.pdpd_DynamicCall 
AS
DECLARE @SQLString_2 NVARCHAR(4000)
SET NOCOUNT ON
Begin
    --- Create global temp table
    CREATE TABLE ##T1 ( column_1 varchar(10) , column_2 varchar(100) )

    SELECT @SQLString_2 = 'INSERT INTO ##T1( column_1, column_2) SELECT column_1 = "123", column_2 = "MUHAMMAD IMRON"'
    SELECT @SQLString_2 = REPLACE(@SQLString_2, '"', '''')

    EXEC SP_EXECUTESQL @SQLString_2

    --- Test Display records
    SELECT * FROM ##T1

    --- Drop global temp table 
    IF OBJECT_ID('tempdb..##T1','u') IS NOT NULL
    DROP TABLE ##T1
End

 byte[] bytes = { 1,2,3,4 };

 string stringByte= BitConverter.ToString(bytes);

 Console.WriteLine(stringByte);

The agg function will do this for you. Pass the columns and function as a dict with column, output:

df.groupby(['Country', 'Item_Code']).agg({'Y1961': np.sum, 'Y1962': [np.sum, np.mean]})  # Added example for two output columns from a single input column

This will display only the group by columns, and the specified aggregate columns. In this example I included two agg functions applied to 'Y1962'.

To get exactly what you hoped to see, included the other columns in the group by, and apply sums to the Y variables in the frame:

df.groupby(['Code', 'Country', 'Item_Code', 'Item', 'Ele_Code', 'Unit']).agg({'Y1961': np.sum, 'Y1962': np.sum, 'Y1963': np.sum})

The easiest way to get data-* attributes is with element.getAttribute():

onclick="fun(this.getAttribute('data-uid'), this.getAttribute('data-name'), this.getAttribute('data-value'));"

DEMO: http://jsfiddle.net/pm6cH/

Although I would suggest just passing this to fun(), and getting the 3 attributes inside the fun function:

onclick="fun(this);"

And then:

function fun(obj) {
    var one = obj.getAttribute('data-uid'),
        two = obj.getAttribute('data-name'),
        three = obj.getAttribute('data-value');
}

DEMO: http://jsfiddle.net/pm6cH/1/

The new way to access them by property is with dataset, but that isn't supported by all browsers. You'd get them like the following:

this.dataset.uid
// and
this.dataset.name
// and
this.dataset.value

DEMO: http://jsfiddle.net/pm6cH/2/

Also note that in your HTML, there shouldn't be a comma here:

data-name="bbb",

When you do from socket import * python is loading a socket module to the current namespace. Thus you can use module's members as if they are defined within your current python module.

When you do import socket, a module is loaded in a separate namespace. When you are accessing its members, you should prefix them with a module name. For example, if you want to refer to a socket class, you will need to write client_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM).

As for the problem with timeout - all you need to do is to change except socket.Timeouterror: to except timeout:, since timeout class is defined inside socket module and you have imported all its members to your namespace.

If you are handling activity's orientation changes with android:configChanges="orientation|screenSize" and onConfigurationChanged(Configuration newConfig), onRestoreInstanceState() will not be called.

Ok after trying soo many things, the correct solution is ...

you need to set DEBUG = 'FALSE' not False or FALSE, but 'FALSE' with ''

You should write in file:

<script>
     //write your JavaScript code here
</script>

save it with .html extension and open with browser.

For example:

// this is test.html
<script>
   alert("Hello");
   var a = 5;
   function incr(arg){
       arg++;
       return arg;
   }       
   alert(a);
</script>

What are raw types in Java, and why do I often hear that they shouldn't be used in new code?

Raw-types are ancient history of the Java language. In the beginning there were Collections and they held Objects nothing more and nothing less. Every operation on Collections required casts from Object to the desired type.

List aList = new ArrayList();
String s = "Hello World!";
aList.add(s);
String c = (String)aList.get(0);

While this worked most of the time, errors did happen

List aNumberList = new ArrayList();
String one = "1";//Number one
aNumberList.add(one);
Integer iOne = (Integer)aNumberList.get(0);//Insert ClassCastException here

The old typeless collections could not enforce type-safety so the programmer had to remember what he stored within a collection.
Generics where invented to get around this limitation, the developer would declare the stored type once and the compiler would do it instead.

List<String> aNumberList = new ArrayList<String>();
aNumberList.add("one");
Integer iOne = aNumberList.get(0);//Compile time error
String sOne = aNumberList.get(0);//works fine

For Comparison:

// Old style collections now known as raw types
List aList = new ArrayList(); //Could contain anything
// New style collections with Generics
List<String> aList = new ArrayList<String>(); //Contains only Strings

More complex the Compareable interface:

//raw, not type save can compare with Other classes
class MyCompareAble implements CompareAble
{
   int id;
   public int compareTo(Object other)
   {return this.id - ((MyCompareAble)other).id;}
}
//Generic
class MyCompareAble implements CompareAble<MyCompareAble>
{
   int id;
   public int compareTo(MyCompareAble other)
   {return this.id - other.id;}
}

Note that it is impossible to implement the CompareAble interface with compareTo(MyCompareAble) with raw types. Why you should not use them:

• Any Object stored in a Collection has to be cast before it can be used
• Using generics enables compile time checks
• Using raw types is the same as storing each value as Object

What the compiler does: Generics are backward compatible, they use the same java classes as the raw types do. The magic happens mostly at compile time.

List<String> someStrings = new ArrayList<String>();
someStrings.add("one");
String one = someStrings.get(0);

Will be compiled as:

List someStrings = new ArrayList();
someStrings.add("one"); 
String one = (String)someStrings.get(0);

This is the same code you would write if you used the raw types directly. Thought I'm not sure what happens with the CompareAble interface, I guess that it creates two compareTo functions, one taking a MyCompareAble and the other taking an Object and passing it to the first after casting it.

What are the alternatives to raw types: Use generics

This is an answer targeting primarily developers using Windows, as the path syntax of the diff tool differs from other platforms.

I use Kdiff3 as the git mergetool, but to set up the git difftool as Meld, I first installed the latest version of Meld from Meldmerge.org then added the following to my global .gitconfig using:

git config --global -e

Note, if you rather want Sublime Text 3 instead of the default Vim as core ditor, you can add this to the .gitconfig file:

[core]
editor = 'c:/Program Files/Sublime Text 3/sublime_text.exe'

Then you add inn Meld as the difftool

[diff]
tool = meld
guitool = meld 

[difftool "meld"]
cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" \"$LOCAL\" \"$REMOTE\" --label \"DIFF 
(ORIGINAL MY)\"
prompt = false
path = C:\\Program Files (x86)\\Meld\\Meld.exe

Note the leading slash in the cmd above, on Windows it is necessary.

It is also possible to set up an alias to show the current git diff with a --dir-diff option. This will list the changed files inside Meld, which is handy when you have altered multiple files (a very common scenario indeed).

The alias looks like this inside the .gitconfig file, beneath [alias] section:

showchanges = difftool --dir-diff

To show the changes I have made to the code I then just enter the following command:

git showchanges

The following image shows how this --dir-diff option can show a listing of changed files (example):

Then it is possible to click on each file and show the changes inside Meld.

Try that - will set it globally:

npm config set msvs_version 2012 --global

For utl_file.open(location,filename,mode) , we need to give directory name for location but not path. For Example:DATA_FILE_DIR , this is the directory name and check out the directory path for that particular directory name.

I also had the same issue. I fixed this by installing the .NET framework version 4.5.

The correct answer is already stated (just use SortedDictionary).

However, if by chance you have some need to retain your collection as Dictionary, it is possible to access the Dictionary keys in an ordered way, by, for example, ordering the keys in a List, then using this list to access the Dictionary. An example...

Dictionary<string, int> dupcheck = new Dictionary<string, int>();

...some code that fills in "dupcheck", then...

if (dupcheck.Count > 0) {
  Console.WriteLine("\ndupcheck (count: {0})\n----", dupcheck.Count);
  var keys_sorted = dupcheck.Keys.ToList();
    keys_sorted.Sort();
  foreach (var k in keys_sorted) {
    Console.WriteLine("{0} = {1}", k, dupcheck[k]);
  }
}

Don't forget using System.Linq; for this.

There's also the TR1/C++11/C++17 way (see it Live on Coliru):

const std::string s[3] = { "1"s, "2"s, "3"s };
constexpr auto n       = std::extent<   decltype(s) >::value; // From <type_traits>
constexpr auto n2      = std::extent_v< decltype(s) >;        // C++17 shorthand

const auto     a    = std::array{ "1"s, "2"s, "3"s };   // C++17 class template arg deduction -- http://en.cppreference.com/w/cpp/language/class_template_argument_deduction
constexpr auto size = std::tuple_size_v< decltype(a) >;

std::cout << n << " " << n2 << " " << size << "\n"; // Prints 3 3 3

textBox1.Text = "Line1\r\r\Line2";
Solved the problem.

Add this before calling dialog

$( obiect ).css('zIndex',9999);

And remove

 zIndex: 700,

from dialog

Also, you may want to try Data::Dumper. Example:

use Data::Dumper;

# simple procedural interface
print Dumper($foo, $bar);

I am facing to this problem so many times till I have 32bit PL/SQL Developer and 64bit Oracle DB or Oracle Client.

The solution is:

1. install a 32bit client.
2. set PLSQL DEV-Tools-Preferencies-Oracle Home to new 32bit client Home
3. set PLSQL DEV-Tools-Preferencies-OCI to new 32 bit home /bin/oci.dll For example: c:\app\admin\product\11.2.0\client_1\BIN\oci.dll
4. Save and restart PLSQL DEV.

Edit or create a TNSNAMES.ORA file in c:\app\admin\product\11.2.0\client_1\NETWORK\admin folder like mentioned above.

Try with TNSPING in console like

C:>tnsping ORCL

If still have problem, set the TNS_ADMIN Enviroment properties value pointing to the folder where the TNSNAMES.ORA located, like: c:\app\admin\product\11.2.0\client_1\network\admin

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

I have a class in one file that I'm importing into a test file:

//Vec.js
class Vec {

}

module.exports.Vec = Vec;

Changing

//Vec.test.js
const Vec = require('./Vec');
const myVec = new Vec(); //TypeError: Vec is not a constructor

to

//Vec.test.js
const {Vec} = require('./Vec');
const myVec = new Vec(); //Succeeds!

resolved this error for me.

I had the same error because I was using proxy. As the answer is given but in case you are using proxy then please set your proxy first using these commands:

git config --global http.proxy http://proxy_username:proxy_password@proxy_ip:port
git config --global https.proxy https://proxy_username:proxy_password@proxy_ip:port

Use std::remove_if algorithm.

Edit:
Work with collections should be like:

1. prepare collection.
2. process collection.

Life will be easier if you won't mix this steps.

1. std::remove_if. or list::remove_if ( if you know that you work with list and not with the TCollection )
2. std::for_each

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } }); 

Fiddle

Update 2:

Xcode 9 appears to have a "feature" where it will ignore the file's current line endings, and instead just use your default line-ending setting when inserting lines into a file, resulting in files with mixed line endings.

I'm pretty sure this bug didn't exist in Xcode 7; not sure about Xcode 8. The good news is that it appears to be fixed in Xcode 10.

For the time it existed, this bug caused a small amount of hilarity in the codebase I refer to in the question (which to this day uses autocrlf=false), and led to many "EOL" commit messages and eventually to my writing a git pre-commit hook to check for/prevent introducing mixed line endings.

Update:

Note: As noted by VonC, starting from Git 2.8, merge markers will not introduce Unix-style line-endings to a Windows-style file.

Original:

One little hiccup that I've noticed with this setup is that when there are merge conflicts, the lines git adds to mark up the differences do not have Windows line-endings, even when the rest of the file does, and you can end up with a file with mixed line endings, e.g.:

// Some code<CR><LF>
<<<<<<< Updated upstream<LF>
// Change A<CR><LF>
=======<LF>
// Change B<CR><LF>
>>>>>>> Stashed changes<LF>
// More code<CR><LF>

This doesn't cause us any problems (I imagine any tool that can handle both types of line-endings will also deal sensible with mixed line-endings--certainly all the ones we use do), but it's something to be aware of.

The other thing^* we've found, is that when using git diff to view changes to a file that has Windows line-endings, lines that have been added display their carriage returns, thus:

    // Not changed

+   // New line added in^M
+^M
    // Not changed
    // Not changed

_{* It doesn't really merit the term: "issue".}

A lot of the times, you are only using the functionality in one place, so making a method just clutters up the class.

Calling this method worked for me. Place it after presenting your view.

[yourViewBeingPresented.view layoutIfNeeded];

You need to add a name attribute.

Since this is a multiple select, at the HTTP level, the client just sends multiple name/value pairs with the same name, you can observe this yourself if you use a form with method="GET": someurl?something=1&something=2&something=3.

In the case of PHP, Ruby, and some other library/frameworks out there, you would need to add square braces ([]) at the end of the name. The frameworks will parse that string and wil present it in some easy to use format, like an array.

Apart from manually parsing the request there's no language/framework/library-agnostic way of accessing multiple values, because they all have different APIs

For PHP you can use:

<select name="something[]" id="inscompSelected" multiple="multiple" class="lstSelected">

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

For those using React, detecting a same-origin iframe load event is as simple as setting onLoad event listener on iframe element.

<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />

earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException. You're calling group(1) without having first called a matching operation (such as find()). This isn't needed if you're just using $1 since the replaceAll() is the matching operation.

You can add different classes to select, or select by type like this:

$('input[type="checkbox"]').removeAttr("disabled");

Maybe something like this (just add your style):

<input type="text" 
       size="35" 
       value="Job Title e.g. Assistant Manager" 
       style="background-color:white; 
              border: solid 1px #6E6E6E;
              height: 30px; 
              font-size:18px; 
              vertical-align:9px;color:#bbb" 
        onfocus="if(this.value == 'Job Title e.g. Assistant Manager') {
                    this.value = '';
                    this.style.color='#000';
                 }" />

<input type="text" 
       name="searchterm" size="35" 
       style="background-color:white; 
              border: solid 1px #6E6E6E;
              height: 30px; 
              font-size:18px; 
              vertical-align:9px" />

UPDATE: Since placeholder attribute is very well supported on all major browsers, there is no need to do anything manually. Its possible to achieve the same thing with this:

<input type="text" 
       size="35" 
       placeholder="Job Title e.g. Assistant Manager" />

Simple answer. If your code has checked="checked" in it change this to unchecked="unchecked"

so your text should look something like this:

input type="checkbox" name="yourchosenname" unchecked="unchecked"

if it doesn't contain this, you could always add it

I see that this problem was discussed some time ago, but if anyone 'll meet with this again, here is my solution:

In your *.cshtml View file:

<script>
var data = JsFunction("@Html.Raw(Model.Path)");
$(function () {
    $("#btn").click(function () {
        var model = { Id: '@Html.Raw(Model.Id)', Data: data }
        $.ajax({
            type: "POST",
            url: "/Controller/Action",
            data: model,
            datatype: "html",
            success: function() {
                console.log('Success');
            }
        });
    });
});
</script>

JavaScript variable model is something that I need to pass to Razor ViewModel. It can be done with ajax request. You just need to have proper argument/s in your action, that matches Json object created in JavaScript.

Hope it'll help someone!

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

...
# Plot several different functions...
labels = []
plotHandles = []
for i in range(1, num_plots + 1):
    x, = plt.plot(some x vector, some y vector) #need the ',' per ** below
    plotHandles.append(x)
    labels.append(some label)
plt.legend(plotHandles, labels, 'upper left',ncol=1)

You can use String.Replace() to replace your desired split string with a character that does not occur in the string and then use String.Split on that character to split the resultant string for the same effect.

Basically, you have three options:

1. Neither specify EXPOSE nor -p
2. Only specify EXPOSE
3. Specify EXPOSE and -p

1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself.

2) If you EXPOSE a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.

3) If you EXPOSE and -p a port, the service in the container is accessible from anywhere, even outside Docker.

The reason why both are separated is IMHO because:

• choosing a host port depends on the host and hence does not belong to the Dockerfile (otherwise it would be depending on the host),
• and often it's enough if a service in a container is accessible from other containers.

The documentation explicitly states:

The EXPOSE instruction exposes ports for use within links.

It also points you to how to link containers, which basically is the inter-container communication I talked about.

PS: If you do -p, but do not EXPOSE, Docker does an implicit EXPOSE. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p includes EXPOSE. That's why I didn't list it above as a fourth case.

If anyone encounter the same issue, when trying to dump from elasticsearch <2.0 to >2.0 you need to do:

elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=analyzer
elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=mapping
elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=data --transform "delete doc.__source['_id']"

First thing first. set the column in which you are working in by clicking on format cells->number-> date and then format e.g Jan-16 representing Jan, 1, 2016. and then apply either of the formulas above.

Another possible solution, in case you're looking for all the words in a given string, which contain a number

Pattern

\w*\d{1,}\w*

• \w* - Matches 0 or more instances of [A-Za-z0-9_]
• \d{1,} - Matches 1 or more instances of a number
• \w* - Matches 0 or more instances of [A-Za-z0-9_]

The whole point in \w* is to allow not having a character in the beginning or at the end of a word. This enables capturing the first and last words in the text.

If the goal here is to only get the numbers without the words, you can omit both \w*.

Given the string

Hello world 1 4m very happy to be here, my name is W1lly W0nk4

Matches

1 4m W1lly W0nk4

Check this example in regexr - https://regexr.com/5ff7q

I have came after another solution to this...here is the code

    $('.selector').popover({
        html: true,
        trigger: 'manual',
        container: $(this).attr('id'),
        placement: 'top',
        content: function () {
            $return = '<div class="hover-hovercard"></div>';
        }
    }).on("mouseenter", function () {
        var _this = this;
        $(this).popover("show");
        $(this).siblings(".popover").on("mouseleave", function () {
            $(_this).popover('hide');
        });
    }).on("mouseleave", function () {
        var _this = this;
        setTimeout(function () {
            if (!$(".popover:hover").length) {
                $(_this).popover("hide")
            }
        }, 100);
    });

Instance of keyword is helpful when you want to know particular object's instance .

Suppose you are throw exception and when you have catch then perform sum custom operation and then again continue as per your logic (throws or log etc)

Example : 1) User created custom exception "InvalidExtensionsException" and throw it as per logic

2) Now in catch block catch (Exception e) { perform sum logic if exception type is "InvalidExtensionsException"

InvalidExtensionsException InvalidException =(InvalidExtensionsException)e;

3) If you are not checking instance of and exception type is Null pointer exception your code will break.

So your logic should be inside of instance of if (e instanceof InvalidExtensionsException){ InvalidExtensionsException InvalidException =(InvalidExtensionsException)e; }

Above example is wrong coding practice However this example is help you to understand use of instance of it.

The BR is anything but 'extra-special': it is still a valid XML tag that you can give attributes to. For example, you don't have to encase it with a span to change the line-height, rather you can apply the line height directly to the element.

You could do it with inline CSS:

This is a small line_x000D_
<br />_x000D_
break. Whereas, this is a BIG line_x000D_
<br />_x000D_
<br style="line-height:40vh"/>_x000D_
break!

Notice how two line breaks were used instead of one. This is because of how CSS inline elements work. Unfourtunately, the most awesome css feature possible (the lh unit) is still not there yet with any browser compatibility as of 2019. Thus, I have to use JavaScript for the demo below.

addEventListener("load", function(document, getComputedStyle){"use strict";_x000D_
  var allShowLineHeights = document.getElementsByClassName("show-lh");_x000D_
  for (var i=0; i < allShowLineHeights.length; i=i+1|0) {_x000D_
    allShowLineHeights[i].textContent = getComputedStyle(_x000D_
      allShowLineHeights[i]_x000D_
    ).lineHeight;_x000D_
  }_x000D_
}.bind(null, document, getComputedStyle), {once: 1, passive: 1});

.show-lh {padding: 0 .25em}_x000D_
.r {background: #f77}_x000D_
.g {background: #7f5}_x000D_
.b {background: #7cf}

This is a small line_x000D_
<span class="show-lh r"></span><br /><span class="show-lh r"></span>_x000D_
break. Whereas, this is a BIG line_x000D_
<span class="show-lh g"></span><br /><span class="show-lh g"></span>_x000D_
<span class="show-lh b"></span><br style="line-height:40vh"/><span class="show-lh b"></span>_x000D_
break!

You can even use any CSS selectors you want like ID's and classes.

#biglinebreakid {_x000D_
  line-height: 450%;_x000D_
  // 9x the normal height of a line break!_x000D_
}_x000D_
.biglinebreakclass {_x000D_
  line-height: 1em;_x000D_
  // you could even use calc!_x000D_
}

This is a small line_x000D_
<br />_x000D_
break. Whereas, this is a BIG line_x000D_
<br />_x000D_
<br id="biglinebreakid" />_x000D_
break! You can use any CSS selectors you want for things like this line_x000D_
<br />_x000D_
<br class="biglinebreakclass" />_x000D_
break!

You can find our more about line-height at the W3C docs.

Basically, BR tags are not some void in world of CSS styling: they still can be styled. However, I would recommend only using line-height to style BR tags. They were never intended to be anything more than a line-break, and as such they might not always work as expected when using them as something else. Observe how even after applying tons of visual effects, the line break is still invisible:

#paddedlinebreak {_x000D_
  display: block;_x000D_
  width: 6em;_x000D_
  height: 6em;_x000D_
  background: orange;_x000D_
  line-height: calc(6em + 100%);_x000D_
  outline: 1px solid red;_x000D_
  border: 1px solid green;_x000D_
}

<div style="outline: 1px solid yellow;margin:1em;display:inline-block;overflow:visible">_x000D_
This is a padded line_x000D_
<br id="paddedlinebreak" />_x000D_
break._x000D_
</div>

A work-around for things such as margins and paddings is to instead style a span with a br in it like so.

#paddedlinebreak {_x000D_
  background: orange;_x000D_
  line-height: calc(6em + 100%);_x000D_
  padding: 3em;_x000D_
}

<div style="outline: 1px solid yellow;margin:1em;display:inline-block;overflow:visible">_x000D_
This is a padded line_x000D_
<span id="paddedlinebreak"><br /></span>_x000D_
break._x000D_
</div>

Notice how the orange blob above is the span that contains the br.

Try phoneNumber.setVisibility(View.GONE);

Update

The below made sense for 2013. However, now, I would use the :not() selector as described below.

CSS can be overwritten.

DEMO: http://jsfiddle.net/persianturtle/J4SUb/

Use this:

.parent {
  padding: 50px;
  border: 1px solid black;
}

.parent span {
  position: absolute;
  top: 200px;
  padding: 30px;
  border: 10px solid green;
}

.parent:hover span {
  border: 10px solid red;
}

.parent span:hover {
  border: 10px solid green;
}

<a class="parent">
    Parent text
    <span>Child text</span>    
</a>

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

I copied the play libs files from the google-play-services_lib to my project libs directory:

• google-play-services.jar
• google-play-services.jar.properties.

Then selected them, right-click, "Add as libraries".

remove any command of "secure_file_priv" in /etc/mysql/my.cnf and restart mysql. If you want to use a file in mysql, copy those files to the main folder. The main folder is obtained this way : SHOW VARIABLES LIKE "secure_file_priv";

As other people have answered, you need to do;

myDropDown.Items.Remove(ListItem li);

but if you want the page to refresh asynchronously, the dropdown needs to be inside an asp:UpdatePanel

after you do the Remove call, you need to call:

yourPanel.Update();

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

A default constructor does not take any arguments:

public class Student {

}

I had this problem. I searched the internet, took all advices, changes configurations, but the problem is still there. Finally with the help of the server administrator, he found that the problem lies in MySQL database column definition. one of the columns in the a table was assigned to 'Longtext' which leads to allocate 4,294,967,295 bites of memory. It seems working OK if you don't use MySqli prepare statement, but once you use prepare statement, it tries to allocate that amount of memory. I changed the column type to Mediumtext which needs 16,777,215 bites of memory space. The problem is gone. Hope this help.

Basic syntax for adding an AUTO_INCREMENT PRIMARY KEY to the OP's existing table:

ALTER TABLE allitems
MODIFY itemid INT(10) UNSIGNED AUTO_INCREMENT PRIMARY KEY;

Or for a new table, here's the syntax example from the docs:

CREATE TABLE animals (
     id MEDIUMINT NOT NULL AUTO_INCREMENT,
     name CHAR(30) NOT NULL,
     PRIMARY KEY (id)
);

Traps and things to note:

• An AUTO_INCREMENT column must have an index on it. (Usually, you'll want it to be the PRIMARY KEY, but MySQL does not require this.)
• It's usually a good idea to make your AUTO_INCREMENT columns UNSIGNED. From the docs:

  Use the UNSIGNED attribute if possible to allow a greater range.

• When using a CHANGE or MODIFY clause to make a column AUTO_INCREMENT (or indeed whenever you use a CHANGE or MODIFY clause) you should be careful to include all modifiers for the column, like NOT NULL or UNSIGNED, that show up in the table definition when you call SHOW CREATE TABLE yourtable. These modifiers will be lost otherwise.

I Created this function:

onAddListItem: function () {
    var Modal = ReactBootstrap.Modal;
    React.render((
        <Modal title='Modal title' onRequestHide={this.hideListItem}>
            <ul class="list-group">
                <li class="list-group-item">Cras justo odio</li>
                <li class="list-group-item">Dapibus ac facilisis in</li>
                <li class="list-group-item">Morbi leo risus</li>
                <li class="list-group-item">Porta ac consectetur ac</li>
                <li class="list-group-item">Vestibulum at eros</li>
            </ul>
        </Modal>
    ), document.querySelector('#modal-wrapper'));
}

And then used it on my Button trigger.

To 'hide' the Modal:

hideListItem: function () {
    React.unmountComponentAtNode(document.querySelector('#modal-wrapper'));
},

You ask specifically about map(), filter() and reduce(), but I assume you want to know about functional programming in general. Having tested this myself on the problem of computing distances between all points within a set of points, functional programming (using the starmap function from the built-in itertools module) turned out to be slightly slower than for-loops (taking 1.25 times as long, in fact). Here is the sample code I used:

import itertools, time, math, random

class Point:
    def __init__(self,x,y):
        self.x, self.y = x, y

point_set = (Point(0, 0), Point(0, 1), Point(0, 2), Point(0, 3))
n_points = 100
pick_val = lambda : 10 * random.random() - 5
large_set = [Point(pick_val(), pick_val()) for _ in range(n_points)]
    # the distance function
f_dist = lambda x0, x1, y0, y1: math.sqrt((x0 - x1) ** 2 + (y0 - y1) ** 2)
    # go through each point, get its distance from all remaining points 
f_pos = lambda p1, p2: (p1.x, p2.x, p1.y, p2.y)

extract_dists = lambda x: itertools.starmap(f_dist, 
                          itertools.starmap(f_pos, 
                          itertools.combinations(x, 2)))

print('Distances:', list(extract_dists(point_set)))

t0_f = time.time()
list(extract_dists(large_set))
dt_f = time.time() - t0_f

Is the functional version faster than the procedural version?

def extract_dists_procedural(pts):
    n_pts = len(pts)
    l = []    
    for k_p1 in range(n_pts - 1):
        for k_p2 in range(k_p1, n_pts):
            l.append((pts[k_p1].x - pts[k_p2].x) ** 2 +
                     (pts[k_p1].y - pts[k_p2].y) ** 2)
    return l

t0_p = time.time()
list(extract_dists_procedural(large_set)) 
    # using list() on the assumption that
    # it eats up as much time as in the functional version

dt_p = time.time() - t0_p

f_vs_p = dt_p / dt_f
if f_vs_p >= 1.0:
    print('Time benefit of functional progamming:', f_vs_p, 
          'times as fast for', n_points, 'points')
else:
    print('Time penalty of functional programming:', 1 / f_vs_p, 
          'times as slow for', n_points, 'points')

If your are using it in windows machine, check whether the selenium webdriver you have installed is of the latest one. I just now explored that my webdriver is of old one and it just opens the firefox but it couldn't process the get function.

Updation of the webdriver resolves this problem

Thanks to dimo414's answer to a similar question, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:

example output

$ ./test.sh

The text from the example function is:
  Welcome dev: Would you "like" to know how many 'files' there are in /tmp?

  There are "      38" files in /tmp, according to the "wc" command

test.sh

#!/bin/bash

function text1()
{
  COUNT=$(\ls /tmp | wc -l)
cat <<EOF

  $1 Would you "like" to know how many 'files' there are in /tmp?

  There are "$COUNT" files in /tmp, according to the "wc" command

EOF
}

function main()
{
  OUT=$(text1 "Welcome dev:")
  echo "The text from the example function is: $OUT"
}

main

The accepted answer by Josh David Miller works great if you are trying to dynamically add a directive that uses an inline template. However if your directive takes advantage of templateUrl his answer will not work. Here is what worked for me:

.directive('helperModal', [, "$compile", "$timeout", function ($compile, $timeout) {
    return {
        restrict: 'E',
        replace: true,
        scope: {}, 
        templateUrl: "app/views/modal.html",
        link: function (scope, element, attrs) {
            scope.modalTitle = attrs.modaltitle;
            scope.modalContentDirective = attrs.modalcontentdirective;
        },
        controller: function ($scope, $element, $attrs) {
            if ($attrs.modalcontentdirective != undefined && $attrs.modalcontentdirective != '') {
                var el = $compile($attrs.modalcontentdirective)($scope);
                $timeout(function () {
                    $scope.$digest();
                    $element.find('.modal-body').append(el);
                }, 0);
            }
        }
    }
}]);

Given the R data.frame:

> df1
  a b c
1 1 1 0
2 1 0 0
3 0 1 0
4 0 0 0

Shuffle row-wise:

> df2 <- df1[sample(nrow(df1)),]
> df2
  a b c
3 0 1 0
4 0 0 0
2 1 0 0
1 1 1 0

By default sample() randomly reorders the elements passed as the first argument. This means that the default size is the size of the passed array. Passing parameter replace=FALSE (the default) to sample(...) ensures that sampling is done without replacement which accomplishes a row wise shuffle.

Shuffle column-wise:

> df3 <- df1[,sample(ncol(df1))]
> df3
  c a b
1 0 1 1
2 0 1 0
3 0 0 1
4 0 0 0

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

You can use get methods:

var fullDate = new Date();_x000D_
console.log(fullDate);_x000D_
var twoDigitMonth = fullDate.getMonth() + "";_x000D_
if (twoDigitMonth.length == 1)_x000D_
    twoDigitMonth = "0" + twoDigitMonth;_x000D_
var twoDigitDate = fullDate.getDate() + "";_x000D_
if (twoDigitDate.length == 1)_x000D_
    twoDigitDate = "0" + twoDigitDate;_x000D_
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear(); console.log(currentDate);

In my case that URL is not working in browser also.

I check with https://www.google.com/

webView.loadUrl("https://www.google.com/")

And it worked for me.

You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build --build-arg arg=2.3 ..

Hello you can access your xampp localhost by

1. Control panel -->
2. windows defender firewall -->
3. Advance setting (on left side) --> Inbound Rules --> New Rule --> Port --> in specific local port write your Apache ports --> next --> next then you can access your localhost by using local PC IP address:

A 404 return code actually means 'resource not found', and applies to any entity for which a request was made but not satisfied. So it works equally-well for pages, subsections of pages, and any item that exists on the page which has a specific request to be rendered.

So 404 is the right code to use in this scenario. Note that it doesn't apply to 'server not found', which is a different situation in which a request was issued but not answered at all, as opposed to answered but without the resource requested.

UPDATE 15.3.2017:

I have opened a Django-issue on this and it seems to be preliminary accepted here: https://code.djangoproject.com/ticket/27825

My experience is that when using the Constructor (ORM) class by references with Django 1.10.5 there might be some inconsistencies in the data (i.e. the attributes of the created object may get the type of the input data instead of the casted type of the ORM object property) example:

models

class Payment(models.Model):
     amount_cash = models.DecimalField()

some_test.py - object.create

Class SomeTestCase:
    def generate_orm_obj(self, _constructor, base_data=None, modifiers=None):
        objs = []
        if not base_data:
            base_data = {'amount_case': 123.00}
        for modifier in modifiers:
            actual_data = deepcopy(base_data)
            actual_data.update(modifier)
            # Hacky fix,
            _obj = _constructor.objects.create(**actual_data)
            print(type(_obj.amount_cash)) # Decimal
            assert created
           objs.append(_obj)
        return objs

some_test.py - Constructor()

Class SomeTestCase:
    def generate_orm_obj(self, _constructor, base_data=None, modifiers=None):
        objs = []
        if not base_data:
            base_data = {'amount_case': 123.00}
        for modifier in modifiers:
            actual_data = deepcopy(base_data)
            actual_data.update(modifier)
            # Hacky fix,
            _obj = _constructor(**actual_data)
            print(type(_obj.amount_cash)) # Float
            assert created
           objs.append(_obj)
        return objs

You may get what you want by using the MySQL REGEXP or LIKE.

In pom.xml file of the project,

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>X.X.X.RELEASE</version>
<relativePath> ../PROJECTNAME/pom.xml</relativePath>

Pointing relativepath to the same MAVEN project POM file solved the issue for me.

I recently came across Python 3 interpreter at CompileOnline.

Wikipedia (or rather, the community on Wikipedia) keeps a pretty good up-to-date list here.

• Most browsers are on 1.5 (though they have features of later versions)
• Mozilla progresses with every dot release (they maintain the standard so that's not surprising)
• Firefox 4 is on JavaScript 1.8.5
• The other big off-the-beaten-path one is IE9 - it implements ECMAScript 5, but doesn't implement all the features of JavaScript 1.8.5 (not sure what they're calling this version of JScript, engine codenamed Chakra, yet).

You can also specify the range with the coord_cartesian command to set the y-axis range that you want, an like in the previous post use scales = free_x

p <- ggplot(plot, aes(x = pred, y = value)) +
     geom_point(size = 2.5) +
     theme_bw()+
     coord_cartesian(ylim = c(-20, 80))
p <- p + facet_wrap(~variable, scales = "free_x")
p

In JavaScript you declare variables or functions by using the keywords var, let or function. In TypeScript classes you declare class members or methods without these keywords followed by a colon and the type or interface of that class member.

It’s just syntax sugar, there is no difference between:

var el: HTMLElement = document.getElementById('content');

and:

var el = document.getElementById('content');

On the other hand, because you specify the type you get all the information of your HTMLElement object.

I tried your code, you didn't assign/bind a value to your formControlName.

In HTML file:

<form [formGroup]="form">
   <label>
     <input type="radio" value="Male" formControlName="gender">
       <span>male</span>
   </label>
   <label>
     <input type="radio" value="Female" formControlName="gender">
       <span>female</span>
   </label>
</form>

In the TS file:

  form: FormGroup;
  constructor(fb: FormBuilder) {
    this.name = 'Angular2'
    this.form = fb.group({
      gender: ['', Validators.required]
    });
  }

Make sure you use Reactive form properly: [formGroup]="form" and you don't need the name attribute.

In my sample. words male and female in span tags are the values display along the radio button and Male and Female values are bind to formControlName

See the screenshot:

To make it shorter:

<form [formGroup]="form">
  <input type="radio" value='Male' formControlName="gender" >Male
  <input type="radio" value='Female' formControlName="gender">Female
</form>

Hope it helps:)

Currently there is no way to precreate an SQLite database to ship with your apk. The best you can do is save the appropriate SQL as a resource and run them from your application. Yes, this leads to duplication of data (same information exists as a resrouce and as a database) but there is no other way right now. The only mitigating factor is the apk file is compressed. My experience is 908KB compresses to less than 268KB.

The thread below has the best discussion/solution I have found with good sample code.

http://groups.google.com/group/android-developers/msg/9f455ae93a1cf152

I stored my CREATE statement as a string resource to be read with Context.getString() and ran it with SQLiteDatabse.execSQL().

I stored the data for my inserts in res/raw/inserts.sql (I created the sql file, 7000+ lines). Using the technique from the link above I entered a loop, read the file line by line and concactenated the data onto "INSERT INTO tbl VALUE " and did another SQLiteDatabase.execSQL(). No sense in saving 7000 "INSERT INTO tbl VALUE "s when they can just be concactenated on.

It takes about twenty seconds on the emulator, I do not know how long this would take on a real phone, but it only happens once, when the user first starts the application.

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

An asynchronously loaded script is likely going to run AFTER the document has been fully parsed and closed. Thus, you can't use document.write() from such a script (well technically you can, but it won't do what you want).

You will need to replace any document.write() statements in that script with explicit DOM manipulations by creating the DOM elements and then inserting them into a particular parent with .appendChild() or .insertBefore() or setting .innerHTML or some mechanism for direct DOM manipulation like that.

For example, instead of this type of code in an inline script:

<div id="container">
<script>
document.write('<span style="color:red;">Hello</span>');
</script>
</div>

You would use this to replace the inline script above in a dynamically loaded script:

var container = document.getElementById("container");
var content = document.createElement("span");
content.style.color = "red";
content.innerHTML = "Hello";
container.appendChild(content);

Or, if there was no other content in the container that you needed to just append to, you could simply do this:

var container = document.getElementById("container");
container.innerHTML = '<span style="color:red;">Hello</span>';

Just increasing max_connections is bad idea. You need to increase shared_buffers and kernel.shmmax as well.

Considerations

max_connections determines the maximum number of concurrent connections to the database server. The default is typically 100 connections.

Before increasing your connection count you might need to scale up your deployment. But before that, you should consider whether you really need an increased connection limit.

Each PostgreSQL connection consumes RAM for managing the connection or the client using it. The more connections you have, the more RAM you will be using that could instead be used to run the database.

A well-written app typically doesn't need a large number of connections. If you have an app that does need a large number of connections then consider using a tool such as pg_bouncer which can pool connections for you. As each connection consumes RAM, you should be looking to minimize their use.

How to increase max connections

1. Increase max_connection and shared_buffers

in /var/lib/pgsql/{version_number}/data/postgresql.conf

change

max_connections = 100
shared_buffers = 24MB

to

max_connections = 300
shared_buffers = 80MB

The shared_buffers configuration parameter determines how much memory is dedicated to PostgreSQL to use for caching data.

• If you have a system with 1GB or more of RAM, a reasonable starting value for shared_buffers is 1/4 of the memory in your system.
• it's unlikely you'll find using more than 40% of RAM to work better than a smaller amount (like 25%)
• Be aware that if your system or PostgreSQL build is 32-bit, it might not be practical to set shared_buffers above 2 ~ 2.5GB.
• Note that on Windows, large values for shared_buffers aren't as effective, and you may find better results keeping it relatively low and using the OS cache more instead. On Windows the useful range is 64MB to 512MB.

2. Change kernel.shmmax

You would need to increase kernel max segment size to be slightly larger than the shared_buffers.

In file /etc/sysctl.conf set the parameter as shown below. It will take effect when postgresql reboots (The following line makes the kernel max to 96Mb)

kernel.shmmax=100663296

Tuning Your PostgreSQL Server

You can also pass value directly via URL.

If you want to call method public static void calling(string name){....}

then you should call usingHttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://localhost:****/Report/calling?name=Priya); webrequest.Method = "GET"; webrequest.ContentType = "application/text";

Just make sure you are using ?Object = value in URL

Now I am using the browser kit like this:

{
border-radius: 7px;
-webkit-border-radius: 7px;
-moz-border-radius: 7px;
}

I like things to happen automatically and for bins to fall on "nice" values. The following seems to work quite well.

import numpy as np
import numpy.random as random
import matplotlib.pyplot as plt
def compute_histogram_bins(data, desired_bin_size):
    min_val = np.min(data)
    max_val = np.max(data)
    min_boundary = -1.0 * (min_val % desired_bin_size - min_val)
    max_boundary = max_val - max_val % desired_bin_size + desired_bin_size
    n_bins = int((max_boundary - min_boundary) / desired_bin_size) + 1
    bins = np.linspace(min_boundary, max_boundary, n_bins)
    return bins

if __name__ == '__main__':
    data = np.random.random_sample(100) * 123.34 - 67.23
    bins = compute_histogram_bins(data, 10.0)
    print(bins)
    plt.hist(data, bins=bins)
    plt.xlabel('Value')
    plt.ylabel('Counts')
    plt.title('Compute Bins Example')
    plt.grid(True)
    plt.show()

The result has bins on nice intervals of bin size.

A 24 hour clock:

setInterval(function(){

        var currentTime = new Date();
        var hours = currentTime.getHours();
        var minutes = currentTime.getMinutes();
        var seconds = currentTime.getSeconds();

        // Add leading zeros
        minutes = (minutes < 10 ? "0" : "") + minutes;
        seconds = (seconds < 10 ? "0" : "") + seconds;
        hours = (hours < 10 ? "0" : "") + hours;

        // Compose the string for display
        var currentTimeString = hours + ":" + minutes + ":" + seconds;
        $(".clock").html(currentTimeString);

},1000);

// 24 hour clock  _x000D_
setInterval(function() {_x000D_
_x000D_
  var currentTime = new Date();_x000D_
  var hours = currentTime.getHours();_x000D_
  var minutes = currentTime.getMinutes();_x000D_
  var seconds = currentTime.getSeconds();_x000D_
_x000D_
  // Add leading zeros_x000D_
  hours = (hours < 10 ? "0" : "") + hours;_x000D_
  minutes = (minutes < 10 ? "0" : "") + minutes;_x000D_
  seconds = (seconds < 10 ? "0" : "") + seconds;_x000D_
_x000D_
  // Compose the string for display_x000D_
  var currentTimeString = hours + ":" + minutes + ":" + seconds;_x000D_
  $(".clock").html(currentTimeString);_x000D_
_x000D_
}, 1000);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="clock"></div>

I also thought this would work but it's misleading:

myStruct _m1 = {0};

When I tried this:

myStruct _m1 = {0xff};

Only the 1st byte was set to 0xff, the remaining ones were set to 0. So I wouldn't get into the habit of using this.

What have you tried? This should work.

h1 { font-size: 20pt; }
h2 { font-size: 16pt; }

sed works with unicode

IFS=$'\n'
for z in $(sed 's/./&\n/g' <(printf '???')); do
 echo hello: "$z"
done

outputs

hello: ?
hello: ?
hello: ?

Ideally, you would create a method on the choice object that found itself in votes, or create a relationship between the models. A template tag that performed the dictionary lookup would work, too.

Try this:

Replace:

audio.load();

with:

audio.play();

I've achieved this by separating them in different , e.g.:

<div class="table">
  <div class="row">
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
    <div class="col">TD</div>
  </div>
</div>
<div class="table">
  <div class="row">
    <div class="col">TD</div>
  </div>
</div>

or you can define different classes for each tables

<div class="table2">
  <div class="row2">
    <div class="col2">TD</div>
  </div>
</div>

From the user point of view they behave identically.

Granted it doesn't solve all colspan/rowspan problems but it does answer my need of the time.

Use a white space to match all descendants of an element:

div.dropdown * {
    color: red;
}

x y matches every element y that is inside x, however deeply nested it may be - children, grandchildren and so on.

The asterisk * matches any element.

Ok, i am shocked that no one really gave a good answer, now my turn. There are two cases;

1. A constant char array is good enough for you so you go with,

   const char *array = tmp.c_str();
   

2. Or you need to modify the char array so constant is not ok, then just go with this

   char *array = &tmp[0];
   

Both of them are just assignment operations and most of the time that is just what you need, if you really need a new copy then follow other fellows answers.

Nunit doesnt work well with mixed-mode projects in C++ so I had to drop it

Since this is so popular I think it is worth pointing out that there is an implementation for this method in ECMA 6 and in preparation for that one should use the 'official' polyfill in order to prevent future problems and tears.

Luckily the experts at Mozilla provide us with one:

https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/String/startsWith

if (!String.prototype.startsWith) {
    String.prototype.startsWith = function(searchString, position) {
        position = position || 0;
        return this.indexOf(searchString, position) === position;
    };
}

Please note that this has the advantage of getting gracefully ignored on transition to ECMA 6.

Thing which works for me is to use padding-bottom on the sibling just before the absolutely-positioned child. Like in your case, it will be like this:

<div style="position: relative; width:600px;">
    <p>Content of unknown length, but quite quite quite quite quite quite quite quite quite quite quite quite quite quite quite quite long</p>
    <div style="padding-bottom: 100px;">Content of unknown height</div>
    <div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px;background-color: red;"></div>
</div>

Well, you can do

DataTable data = (DataTable)(dgvMyMembers.DataSource);

and then use

data.Columns.Remove(...);

I think it's the fastest way. This will modify data source table, if you don't want it, then copy of table is reqired. Also be aware that DataGridView.DataSource is not necessarily of DataTable type.

For Python versions in 2.6+ and 3.x

You can use the str.format method. Examples:

>>> print('{0:.16f}'.format(1.6))
1.6000000000000001

>>> print('{0:.15f}'.format(1.6))
1.600000000000000

Note the 1 at the end of the first example is rounding error; it happens because exact representation of the decimal number 1.6 requires an infinite number binary digits. Since floating-point numbers have a finite number of bits, the number is rounded to a nearby, but not equal, value.

For Python versions prior to 2.6 (at least back to 2.0)

You can use the "modulo-formatting" syntax (this works for Python 2.6 and 2.7 too):

>>> print '%.16f' % 1.6
1.6000000000000001

>>> print '%.15f' % 1.6
1.600000000000000

I think this should work,

a = numpy.arange(0,27.,3).reshape(3,3)

a /=  a.sum(axis=1)[:,numpy.newaxis]

TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)

Here is the FIX for 2.3 and below when using colours:

• Android: Entire ListView changes color on focus, not just ListView child item

As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape drawable containing the colour you want, and to use that instead of the colour.

I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

Using **kwargs and default values is easy. Sometimes, however, you shouldn't be using **kwargs in the first place.

In this case, we're not really making best use of **kwargs.

class ExampleClass( object ):
    def __init__(self, **kwargs):
        self.val = kwargs.get('val',"default1")
        self.val2 = kwargs.get('val2',"default2")

The above is a "why bother?" declaration. It is the same as

class ExampleClass( object ):
    def __init__(self, val="default1", val2="default2"):
        self.val = val
        self.val2 = val2

When you're using **kwargs, you mean that a keyword is not just optional, but conditional. There are more complex rules than simple default values.

When you're using **kwargs, you usually mean something more like the following, where simple defaults don't apply.

class ExampleClass( object ):
    def __init__(self, **kwargs):
        self.val = "default1"
        self.val2 = "default2"
        if "val" in kwargs:
            self.val = kwargs["val"]
            self.val2 = 2*self.val
        elif "val2" in kwargs:
            self.val2 = kwargs["val2"]
            self.val = self.val2 / 2
        else:
            raise TypeError( "must provide val= or val2= parameter values" )

Apple cares about security and as you know it is not possible to install any application on a real iOS device. Apple has several legal ways to do it:

• When you need to test/debug an app on a real device the Development Provisioning Profile allows you to do it
• When you publish an app you send a Distribution Provisioning Profile^[About] and Apple after review reassign it by they own key

Development Provisioning Profile is stored on device and contains:

• Application ID - application which are going to run
• List of Development certificates - who can debug the app
• List of devices - which devices can run this app

Xcode by default take cares about

in google colabs if this is your first time,

from google.colab import drive
drive.mount('/content/drive')

run these codes and go through the outputlink then past the pass-prase to the box

when you copy you can copy as follows, go to file right click and copy the path ***don't forget to remove " /content "

f = open("drive/My Drive/RES/dimeric_force_field/Test/python_read/cropped.pdb", "r")

Use this:

$root = 'REST_SERVICE_URL'
$user = "user"
$pass= "password"
$secpasswd = ConvertTo-SecureString $pass -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential($user, $secpasswd)

$result = Invoke-RestMethod $root -Credential $credential
