Your other option is to initialize j:

j = [None] * len(i)

from the docs

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

i applied the .navbar-text class to my <li> element, so the result is

<li class="nav-item navbar-text">

this centers the links vertically with respect to my navbar-brand img

Option 3

To update current iframe

$("iframe").wrap('<div class="embed-responsive embed-responsive-16by9"/>');
$("iframe").addClass('embed-responsive-item');

i think better to do this

    if ( $request->hasFile('file')){
        if ($request->file('file')->isValid()){
            $file = $request->file('file');
            $name = $file->getClientOriginalName();
            $file->move('images' , $name);
            $inputs = $request->all();
            $inputs['path'] = $name;
        }
    }
    Post::create($inputs);

actually images is folder that laravel make it automatic and file is name of the input and here we store name of the image in our path column in the table and store image in public/images directory

i've written a function that extract numbers from string:

int SnirElgabsi::GetNumberFromCString(CString src, CString str, int length) {
   // get startIndex
   int startIndex = src.Find(str) + CString(str).GetLength();
   // cut the string
   CString toreturn = src.Mid(startIndex, length);
   // convert to number
   return _wtoi(toreturn); // atoi(toreturn)
}

Usage:

CString str = _T("digit:1, number:102");
int  digit = GetNumberFromCString(str, _T("digit:"), 1);
int number = GetNumberFromCString(str, _T("number:"), 3);

I had to create a timer for teachers grading students' work. Here's one I used which is entirely based on elapsed time since the grading begun by storing the system time at the point that the page is loaded, and then comparing it every half second to the system time at that point:

var startTime = Math.floor(Date.now() / 1000); //Get the starting time (right now) in seconds
localStorage.setItem("startTime", startTime); // Store it if I want to restart the timer on the next page

function startTimeCounter() {
    var now = Math.floor(Date.now() / 1000); // get the time now
    var diff = now - startTime; // diff in seconds between now and start
    var m = Math.floor(diff / 60); // get minutes value (quotient of diff)
    var s = Math.floor(diff % 60); // get seconds value (remainder of diff)
    m = checkTime(m); // add a leading zero if it's single digit
    s = checkTime(s); // add a leading zero if it's single digit
    document.getElementById("idName").innerHTML = m + ":" + s; // update the element where the timer will appear
    var t = setTimeout(startTimeCounter, 500); // set a timeout to update the timer
}

function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10
    return i;
}

startTimeCounter();

This way, it really doesn't matter if the 'setTimeout' is subject to execution delays, the elapsed time is always relative the system time when it first began, and the system time at the time of update.

SVG 1.2 Tiny has viewport-fill I'm not sure how widely implemented this property is though as most browsers are targetting SVG 1.1 at this time. Opera implements it FWIW.

A more cross-browser solution currently would be to stick a <rect> element with width and height of 100% and fill="red" as the first child of the <svg> element, for example:

<rect width="100%" height="100%" fill="red"/>

Bootstrap has it's own centering class named text-center.

<div class="span7 text-center"></div>

In Laravel 5.1 I needed a global variable populated with model data accessible in all views.

I followed a similar approach to ollieread's answer and was able to use my variable ($notifications) in any view.

My controller location: /app/Http/Controllers/Controller.php

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

use App\Models\Main as MainModel;
use View;

abstract class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function __construct() {
        $oMainM = new MainModel;
        $notifications = $oMainM->get_notifications();
        View::share('notifications', $notifications);
    }
}

My model location: /app/Models/Main.php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use DB;

class Main extends Model
{
    public function get_notifications() {...

We are use modal form with BackgroundWorker for such a thing.

Here is quick solution:

  public class ProgressWorker<TArgument> : BackgroundWorker where TArgument : class 
    {
        public Action<TArgument> Action { get; set; }

        protected override void OnDoWork(DoWorkEventArgs e)
        {
            if (Action!=null)
            {
                Action(e.Argument as TArgument);
            }
        }
    }


public sealed partial class ProgressDlg<TArgument> : Form where TArgument : class
{
    private readonly Action<TArgument> action;

    public Exception Error { get; set; }

    public ProgressDlg(Action<TArgument> action)
    {
        if (action == null) throw new ArgumentNullException("action");
        this.action = action;
        //InitializeComponent();
        //MaximumSize = Size;
        MaximizeBox = false;
        Closing += new System.ComponentModel.CancelEventHandler(ProgressDlg_Closing);
    }
    public string NotificationText
    {
        set
        {
            if (value!=null)
            {
                Invoke(new Action<string>(s => Text = value));  
            }

        }
    }
    void ProgressDlg_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        FormClosingEventArgs args = (FormClosingEventArgs)e;
        if (args.CloseReason == CloseReason.UserClosing)
        {
            e.Cancel = true;
        }
    }



    private void ProgressDlg_Load(object sender, EventArgs e)
    {

    }

    public void RunWorker(TArgument argument)
    {
        System.Windows.Forms.Application.DoEvents();
        using (var worker = new ProgressWorker<TArgument> {Action = action})
        {
            worker.RunWorkerAsync();
            worker.RunWorkerCompleted += worker_RunWorkerCompleted;                
            ShowDialog();
        }
    }

    void worker_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
    {
        if (e.Error != null)
        {
            Error = e.Error;
            DialogResult = DialogResult.Abort;
            return;
        }

        DialogResult = DialogResult.OK;
    }
}

And how we use it:

var dlg = new ProgressDlg<string>(obj =>
                                  {
                                     //DoWork()
                                     Thread.Sleep(10000);
                                     MessageBox.Show("Background task completed "obj);
                                   });
dlg.RunWorker("SampleValue");
if (dlg.Error != null)
{
  MessageBox.Show(dlg.Error.Message, "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
dlg.Dispose();

Based on the answer of @macetw I print the exception directly to stderr in a decorator.

Python 3

from functools import wraps
from sys import stderr
from traceback import format_exc
from typing import Callable, Collection, Any, Mapping


def force_error_output(func: Callable):
    @wraps(func)
    def forced_error_output(*args: Collection[Any], **kwargs: Mapping[str, Any]):
        nonlocal func

        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Python 2

from functools import wraps
from sys import stderr
from traceback import format_exc


def force_error_output(func):
    @wraps(func)
    def forced_error_output(*args, **kwargs):
        try:
            func(*args, **kwargs)
        except Exception as exception:
            stderr.write(format_exc())
            stderr.write("\n")
            stderr.flush()

            raise exception

    return forced_error_output

Then in your worker just use the decorator

@force_error_output
def da_worker(arg1: int, arg2: str):
    pass

Basically, the problem lies in block12. for the block1/2 to take up the total height of the block12, it must have a defined height. This stack overflow post explains that in really good detail.

So setting a defined height for block12 will allow you to set a proper height. I have created an example on JSfiddle that will show you the the blocks can be floated next to one another if the block12 div is set to a standard height through out the page.

Here is an example including a header and block3 div with some content in for examples.

#header{
   position:absolute;
   top:0;
   left:0;
   width:100%;
   height:20%;
    }

    #block12{
    position:absolute;
    top:20%;
    width:100%;
    left:0;
    height:40%;
    }
    #block1,#block2{
    float:left;
    overflow-y: scroll;
    text-align:center;
    color:red;
    width:50%;
    height:100%;

    }
 #clear{clear:both;}
 #block3{
    position:absolute;
    bottom:0;
    color:blue;
    height:40%;

    }

small addendum: scrolls only, if last line is already visible. if scrolled a tiny bit, leaves the content where it is (attention: not tested with different font sizes. this may need some adjustments inside ">= comparison"):

var objDiv = document.getElementById(id);
var doScroll=objDiv.scrollTop>=(objDiv.scrollHeight-objDiv.clientHeight);                   

// add new content to div
$('#' + id ).append("new line at end<br>"); // this is jquery!

// doScroll is true, if we the bottom line is already visible
if( doScroll) objDiv.scrollTop = objDiv.scrollHeight;

To indicate progress of activity, try the following commands:

while true; do sleep 0.25 && echo -ne "\r\\" && sleep 0.25 && echo -ne "\r|" && sleep 0.25 && echo -ne "\r/" && sleep 0.25 && echo -ne "\r-"; done;

OR

while true; do sleep 0.25 && echo -ne "\rActivity: \\" && sleep 0.25 && echo -ne "\rActivity: |" && sleep 0.25 && echo -ne "\rActivity: /" && sleep 0.25 && echo -ne "\rActivity: -"; done;

OR

while true; do sleep 0.25 && echo -ne "\r" && sleep 0.25 && echo -ne "\r>" && sleep 0.25 && echo -ne "\r>>" && sleep 0.25 && echo -ne "\r>>>"; sleep 0.25 && echo -ne "\r>>>>"; done;

OR

while true; do sleep .25 && echo -ne "\r:Active:" && sleep .25 && echo -ne "\r:aCtive:" && sleep .25 && echo -ne "\r:acTive:" && sleep .25 && echo -ne "\r:actIve:" && sleep .25 && echo -ne "\r:actiVe:" && sleep .25 && echo -ne "\r:activE:"; done;

One can use flags/variables inside the while loop to check and display the value/extent of progress.

If you are using lodash or underscore the _.countBy method will provide an object of aggregate totals keyed by each value in the array. You can turn this into a one-liner if you only need to count one value:

_.countBy(['foo', 'foo', 'bar'])['foo']; // 2

This also works fine on arrays of numbers. The one-liner for your example would be:

_.countBy([1, 2, 3, 5, 2, 8, 9, 2])[2]; // 3

Just append() the text nodes:

$('#replyBox').append(quote);

MacOSX here. I had the same problem after upgrading my postresql install from a pre-9.1 to 9.1.2 using homebrew. (By the way, remember to dump databases before your upgrade with pg_dump, pre-9.1 databases are incompatible.) Same problem, same error messages.

Uninstalling the pg gem did the trick for me. I actually had to do quite a bit of dancing to discover the issue. First I did a global gem uninstall, clearing the deck of all the old gems (there were a few). Then I removed pg from my Gemfile, rebundled, restored the pg reference, and rebounded once more.

After that, it worked like a charm.

Here's a more valid way which also check if your textbox is filled with only blanks.

// When spaces are not allowed
if (string.IsNullOrWhiteSpace(txtBox1.Text) || string.IsNullOrWhiteSpace(txtBox2.Text))
  //...give error...

// When spaces are allowed
if (string.IsNullOrEmpty(txtBox1.Text) || string.IsNullOrEmpty(txtBox2.Text))
  //...give error...

The edited answer of @Habib.OSU is also fine, this is just another approach.

os.chdir() is the right way.

You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.

I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).

To install it, you can either download it from the linked website or use the command:

pip install pyinstaller

...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:

pyinstaller myscript.py

You can find more information about how to use Pyinstaller and customize the build process via the documentation.

You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.

please add all suport

app/build.gradle

ndk {
        moduleName "serial_port"
        ldLibs "log", "z", "m"
        abiFilters "arm64-v8a","armeabi", "armeabi-v7a", "x86","x86_64","mips","mips64"
}

app\src\jni\Application.mk

APP_ABI := arm64-v8a armeabi armeabi-v7a x86 x86_64 mips mips64

rgrep . | wc -l

gives the count of non blank lines in the current working directory.

This might work for you:

sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1

As what Jakob said: windows sdk 7.1 cannot be installed if MS VC++ x64 and x86 runtimes and redisrtibutables of version 10.0.40219 are present. after removing them win sdk install is okay, VS C++ SP1 can be installed fine again.

Kind regards

You actually don't need to pass a body to match_all, it can be done with a GET request to the following URL. This is the simplest form.

You have two versions of ADB

$ /usr/local/bin/adb version
Android Debug Bridge version 1.0.36

You could see which one your PATH is pointing to (echo $PATH) but I fixed it with a adb stop-server on one version and a adb start-server on the other.

You can create a unix timestamp date from a date this way:

Following this answer created a simple but convenient instrument.

import time
from datetime import timedelta

def start_time_measure(message=None):
    if message:
        print(message)
    return time.monotonic()

def end_time_measure(start_time, print_prefix=None):
    end_time = time.monotonic()
    if print_prefix:
        print(print_prefix + str(timedelta(seconds=end_time - start_time)))
    return end_time

Usage:

total_start_time = start_time_measure()    
start_time = start_time_measure('Doing something...')
# Do something
end_time_measure(start_time, 'Done in: ')
start_time = start_time_measure('Doing something else...')
# Do something else
end_time_measure(start_time, 'Done in: ')
end_time_measure(total_start_time, 'Total time: ')

The output:

Doing something...
Done in: 0:00:01.218000
Doing something else...
Done in: 0:00:01.313000
Total time: 0:00:02.672000

$query    =    "SELECT username, userid FROM user WHERE username = 'admin' ";
$result    =    $conn->query($query);

if (!$result) {
  echo 'Could not run query: ' . mysql_error();
  exit;
}

$arrayResult    =    mysql_fetch_array($result);

//Now you can access $arrayResult like this

$arrayResult['userid'];    // output will be userid which will be in database
$arrayResult['username'];  // output will be admin

//Note- userid and username will be column name of user table.

Didn't find the answer I wanted, so I solved it myself:
modify a container div!

<div class="rotation"> <!-- Set the container div's css -->
  <div class="content" id='content-1'>This div gets scaled on hover</div>
</div>

<!-- Since there is no parent here the transform doesnt have specificity! -->
<div class="rotation content" id='content-2'>This div does not</div>

css you want to persist after executing $target.css()

.content:hover {
    transform: scale(1.5);
}

modify content's containing div with css()

$(".rotation").css("transform", "rotate(" + degrees + "deg)");

Codepen example

Here is some code:

K.set_learning_phase(1)
K.set_image_data_format('channels_last')

tb_callback = keras.callbacks.TensorBoard(
    log_dir=log_path,
    histogram_freq=2,
    write_graph=True
)
tb_callback.set_model(model)
callbacks = []
callbacks.append(tb_callback)

# Train net:
history = model.fit(
    [x_train],
    [y_train, y_train_c],
    batch_size=int(hype_space['batch_size']),
    epochs=EPOCHS,
    shuffle=True,
    verbose=1,
    callbacks=callbacks,
    validation_data=([x_test], [y_test, y_test_coarse])
).history

# Test net:
K.set_learning_phase(0)
score = model.evaluate([x_test], [y_test, y_test_coarse], verbose=0)

Basically, histogram_freq=2 is the most important parameter to tune when calling this callback: it sets an interval of epochs to call the callback, with the goal of generating fewer files on disks.

So here is an example visualization of the evolution of values for the last convolution throughout training once seen in TensorBoard, under the "histograms" tab (and I found the "distributions" tab to contain very similar charts, but flipped on the side):

In case you would like to see a full example in context, you can refer to this open-source project: https://github.com/Vooban/Hyperopt-Keras-CNN-CIFAR-100

Update March 2013

The expiry date of the provisioning profile is linked to the expiry date of the developer certificate. And I didn't want to wait for it to expire so here is what I did -

• Go to the iOS Provisioning portal
• Revoke the current certificate
• In Xcode > Organizer go to the Provisioning profiles page (under Library)
• Press refresh and it will prompt you to create a new developer certificate since the current one has been revoked
• Follow the steps to create one
• Go back to the iOS provisioning portal for your distribution profiles and change something about it so it will enable the submit button.
• Submit it and the date of the new certificate will get applied to it

The below code will help you to auto open the .exe file from excel...

I tried to alter the table and set auto_increment to 1 but it did not work. I resolved to delete the column name I was incrementing, then create a new column with your preferred name and set that new column to increment from the onset.

Don't forget, if you are also on a machine where you haven't set up heroku before

heroku keys:add

Or you won't be able to push or pull to the repo.

If you just want the column names, then

select COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'tablename'

On MS SQL Server, for more information on the table such as the types of the columns, use

sp_help 'tablename'

You can send the file and data over in one request using the multipart/form-data content type:

In many applications, it is possible for a user to be presented with a form. The user will fill out the form, including information that is typed, generated by user input, or included from files that the user has selected. When the form is filled out, the data from the form is sent from the user to the receiving application.

The definition of MultiPart/Form-Data is derived from one of those applications...

From http://www.faqs.org/rfcs/rfc2388.html:

"multipart/form-data" contains a series of parts. Each part is expected to contain a content-disposition header [RFC 2183] where the disposition type is "form-data", and where the disposition contains an (additional) parameter of "name", where the value of that parameter is the original field name in the form. For example, a part might contain a header:

Content-Disposition: form-data; name="user"

with the value corresponding to the entry of the "user" field.

You can include file information or field information within each section between boundaries. I've successfully implemented a RESTful service that required the user to submit both data and a form, and multipart/form-data worked perfectly. The service was built using Java/Spring, and the client was using C#, so unfortunately I don't have any Grails examples to give you concerning how to set up the service. You don't need to use JSON in this case since each "form-data" section provides you a place to specify the name of the parameter and its value.

The good thing about using multipart/form-data is that you're using HTTP-defined headers, so you're sticking with the REST philosophy of using existing HTTP tools to create your service.

From the python command prompt:

import scipy
print scipy.__version__

In python 3 you'll need to change it to:

print (scipy.__version__)

In my project , I use the XMLHttpRequest to send multipart/form-data. I think it will fit you to.

and the uploader code

let xhr = new XMLHttpRequest();
xhr.open('POST', 'http://www.example.com/rest/api', true);
xhr.withCredentials = true;
xhr.send(formData);

Here is example : https://github.com/wangzilong/angular2-multipartForm

You have to add this permission in Info.plist for iOS 10.

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

"This was a bug on the Apple portal site. They were missing a necessary field in the provisioning profile. They fixed this bug late on 6/16/09. "

Let's say alice is a github.com user, with 2 or more private repositories repoN. For this example we'll work with just two repositories named repo1 and repo2

https://github.com/alice/repo1

https://github.com/alice/repo2

You need to be to pull from these repositories without entering a passwords probably on a server, or on multiple servers. You want to perform git pull origin master for example, and you want this to happen without asking for a password.

You don't like dealing with ssh-agent, you have discovered (or you're discovering now) about ~/.ssh/config a file that let's your ssh client know what private key to use depending on Hostname and username, with a simple configuration entry that looks like this:

Host github.com
  HostName github.com
  User git
  IdentityFile /home/alice/.ssh/alice_github.id_rsa
  IdentitiesOnly yes

So you went ahead and created your (alice_github.id_rsa, alice_github.id_rsa.pub) keypair, you then also went to your repository's .git/config file and you modified the url of your remote origin to be something like this:

[remote "origin"]
        url = "ssh://[email protected]/alice/repo1.git"

And finally you went to the repository Settings > Deploy keys section and added the contents of alice_github.id_rsa.pub

At this point you could do your git pull origin master without entering a password without issue.

but what about the second repository?

So your instinct will be to grab that key and add it to repo2's Deploy keys, but github.com will error out and tell you that the key is already being used.

Now you go and generate another key (using ssh-keygen -t rsa -C "[email protected]" without passwords of course), and so that this doesn't become a mess, you will now name your keys like this:

• repo1 keypair: (repo1.alice_github.id_rsa, repo1.alice_github.id_rsa.pub)
• repo2 keypair: (repo2.alice_github.id_rsa, repo2.alice_github.id_rsa.pub)

You will now put the new public key on repo2's Deploy keys configuration at github.com, but now you have an ssh problem to deal with.

How can ssh tell which key to use if the repositories are hosted on the same github.com domain?

Your .ssh/config file points to github.com and it doesn't know which key to use when it's time to do the pull.

So I found a trick with github.com. You can tell your ssh client that each repository lives in a different github.com subdomain, in these cases, they will be repo1.github.com and repo2.github.com

So first thing is editing the .git/config files on your repo clones, so they look like this instead:

For repo1

[remote "origin"]
        url = "ssh://[email protected]/alice/repo1.git"

For repo2

[remote "origin"]
        url = "ssh://[email protected]/alice/repo2.git"

And then, on your .ssh/config file, now you will be able to enter a configuration for each subdomain :)

Host repo1.github.com
  HostName github.com
  User git
  IdentityFile /home/alice/.ssh/repo1.alice_github.id_rsa
  IdentitiesOnly yes

Host repo2.github.com
  HostName github.com
  User git
  IdentityFile /home/alice/.ssh/repo2.alice_github.id_rsa
  IdentitiesOnly yes

Now you are able to git pull origin master without entering any passwords from both repositories.

If you have multiple machines, you could copy the keys to each of the machines and reuse them, but I'd advise doing the leg work to generate 1 key per machine and repo. You will have a lot more keys to handle, but you will be less vulnerable if one gets compromised.

Another solution is to create a normal class which implements PropertyChanger like this

public class ViewProps : PropertyChanger
{
    private string _MyValue = string.Empty;
    public string MyValue
    {
        get { 
            return _MyValue
        }
        set
        {
            if (_MyValue == value)
            {
                return;
            }
            SetProperty(ref _MyValue, value);
        }
    }
}

Then create a static instance of the class somewhere you wont

public class MyClass
{
    private static ViewProps _ViewProps = null;
    public static ViewProps ViewProps
    {
        get
        {
            if (_ViewProps == null)
            {
                _ViewProps = new ViewProps();
            }
            return _ViewProps;
        }
    }
}

And now use it as static property

<TextBlock  Text="{x:Bind local:MyClass.ViewProps.MyValue, Mode=OneWay}"  />

And here is PropertyChanger implementation if necessary

public abstract class PropertyChanger : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null)
    {
        if (object.Equals(storage, value)) return false;

        storage = value;
        OnPropertyChanged(propertyName);
        return true;
    }

    protected void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

Functional answer using flatMap:

const getPermutationsFor = (arr, permutation = []) =>
  arr.length === 0
    ? [permutation]
    : arr.flatMap((item, i, arr) =>
        getPermutationsFor(
          arr.filter((_,j) => j !== i),
          [...permutation, item]
        )
      );

This does exactly what you want, modified from Will's earlier post. No need for helper tables or loops.

WITH date_range (calc_date) AS (
    SELECT DATEADD(DAY, DATEDIFF(DAY, 0, '2010-01-13') - DATEDIFF(DAY, '2010-01-01', '2010-01-13'), 0)
        UNION ALL SELECT DATEADD(DAY, 1, calc_date)
            FROM date_range
            WHERE DATEADD(DAY, 1, calc_date) <= '2010-01-13')
SELECT calc_date
FROM date_range;

How big is m?

You could do something like:

create table two select null foo union all select null;
create temporary table seq ( foo int primary key auto_increment ) auto_increment=9 select a.foo from two a, two b, two c, two d;
select * from seq where foo <= 23;

where the auto_increment is set to n and the where clause compares to m and the number of times the two table is repeated is at least ceil(log(m-n+1)/log(2)).

(The non-temporary two table could be omitted by replacing two with (select null foo union all select null) in the create temporary table seq.)

SWIFT 4 with extension

set:

// set button label for all states
extension UIButton {
    public func setAllStatesTitle(_ newTitle: String){
        self.setTitle(newTitle, for: .normal)
        self.setTitle(newTitle, for: .selected)
        self.setTitle(newTitle, for: .disabled)
    }
}

and use:

yourBtn.setAllStatesTitle("btn title")

FYI

Here is another PoC implementation:

• without any libraries (e.g. lodash) for debouncing
• using React Hooks API

I hope it helps :)

import React, { useState, useEffect, ChangeEvent } from 'react';

export default function DebouncedSearchBox({
  inputType,
  handleSearch,
  placeholder,
  debounceInterval,
}: {
  inputType?: string;
  handleSearch: (q: string) => void;
  placeholder: string;
  debounceInterval: number;
}) {
  const [query, setQuery] = useState<string>('');
  const [timer, setTimer] = useState<NodeJS.Timer | undefined>();

  useEffect(() => {
    if (timer) {
      clearTimeout(timer);
    }
    setTimer(setTimeout(() => {
      handleSearch(query);
    }, debounceInterval));
  }, [query]);

  const handleOnChange = (e: ChangeEvent<HTMLInputElement>): void => {
    setQuery(e.target.value);
  };

  return (
    <input
      type={inputType || 'text'}
      className="form-control"
      placeholder={placeholder}
      value={query}
      onChange={handleOnChange}
    />
  );
}

in laravel used decimal column type for migration

$table->decimal('latitude', 10, 8);
$table->decimal('longitude', 11, 8);

If you just want to execute the shell command in your c program, you could use,

   #include <stdlib.h>

   int system(const char *command);

In your case,

system("pwd");

The issue is that there isn't an executable file called "pwd" and I'm unable to execute "echo $PWD", since echo is also a built-in command with no executable to be found.

What do you mean by this? You should be able to find the mentioned packages in /bin/

sudo find / -executable -name pwd
sudo find / -executable -name echo

Great answer by Lee Jarvis, this is just the command e.g; we already have an existing model called User:

rails g scaffold_controller User

In Mac there is a fast method with brew:

brew search node

You see some version, for example: node@10 node@12 ... Then

brew unlink node

And now select a before version for example node@12

brew link --overwrite --force node@12

Ready, you have downgraded you node version.

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

First you will need some GUI library with Python bindings and then (if you want) some program that will convert your python scripts into standalone executables.

Cross-platform GUI libraries with Python bindings (Windows, Linux, Mac)

Of course, there are many, but the most popular that I've seen in wild are:

• Tkinter - based on Tk GUI toolkit (de-facto standard GUI library for python, free for commercial projects)
• WxPython - based on WxWidgets (popular, free for commercial projects)
• Qt using the PyQt bindings or Qt for Python. The former is not free for commercial projects. The latter is less mature, but can be used for free.

Complete list is at http://wiki.python.org/moin/GuiProgramming

Single executable (all platforms)

• PyInstaller - the most active(Could also be used with PyQt)
• fbs - if you chose Qt above

Single executable (Windows)

• py2exe - used to be the most popular

Single executable (Linux)

• Freeze - works the same way like py2exe but targets Linux platform

Single executable (Mac)

• py2app - again, works like py2exe but targets Mac OS

In the function declaration you have to type as

VOID FUN(INT *a[]);
/*HERE YOU CAN TAKE ANY FUNCTION RETURN TYPE HERE I CAN TAKE VOID AS THE FUNCTION RETURN  TYPE FOR THE FUNCTION FUN*/
//IN THE FUNCTION HEADER WE CAN WRITE AS FOLLOWS
void fun(int *a[])
//in the function body we can use as
a[i]=var

Assume you have the following Home route definition

<Route exact path="/" render={routeProps => (
   <Home routeProps={routeProps}/>
)}/>

{/*optional catch-all router */}
<Route render={routeProps => (
       <div><h4>404 not found</h4></div>
)}/>

At your Home component, you can intercept the request at ComponentWillMount event,

const searchPath = this.props.routeProps.location.search;

if (searchPath){
    this.props.routeProps.history.push("/" + searchPath.replace("?",""));
}
else{
    /*.... originally Home event */
}

Now, instead of calling /joblist at url, you can request /?joblist, and the Component will auto redirect the request to /joblist (take note the extra question mark in the path)

Solution:

Add the below line in your application tag:

android:usesCleartextTraffic="true"

As shown below:

<application
    ....
    android:usesCleartextTraffic="true"
    ....>

UPDATE: If you have network security config such as: android:networkSecurityConfig="@xml/network_security_config"

No Need to set clear text traffic to true as shown above, instead use the below code:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        ....
        ....
    </domain-config>

    <base-config cleartextTrafficPermitted="false"/>
</network-security-config>  

Set the cleartextTrafficPermitted to true

Hope it helps.

And in 2016.....I do this (which works in all browsers and does not create "illegal" html).

For the drop-down select that is to show/hide different values add that value as a data attribute.

<select id="animal">
    <option value="1" selected="selected">Dog</option>
    <option value="2">Cat</option>
</select>
<select id="name">
    <option value=""></option>
    <option value="1" data-attribute="1">Rover</option>
    <option value="2" selected="selected" data-attribute="1">Lassie</option>
    <option value="3" data-attribute="1">Spot</option>
    <option value="4" data-attribute="2">Tiger</option>
    <option value="5" data-attribute="2">Fluffy</option>
</select>

Then in your jQuery add a change event to the first drop-down select to filter the second drop-down.

$("#animal").change( function() {
    filterSelectOptions($("#name"), "data-attribute", $(this).val());
});

And the magic part is this little jQuery utility.

function filterSelectOptions(selectElement, attributeName, attributeValue) {
    if (selectElement.data("currentFilter") != attributeValue) {
        selectElement.data("currentFilter", attributeValue);
        var originalHTML = selectElement.data("originalHTML");
        if (originalHTML)
            selectElement.html(originalHTML)
        else {
            var clone = selectElement.clone();
            clone.children("option[selected]").removeAttr("selected");
            selectElement.data("originalHTML", clone.html());
        }
        if (attributeValue) {
            selectElement.children("option:not([" + attributeName + "='" + attributeValue + "'],:not([" + attributeName + "]))").remove();
        }
    }
}

This little gem tracks the current filter, if different it restores the original select (all items) and then removes the filtered items. If the filter item is empty we see all items.

The problem comes from your Java application (or a library you are using).

First, you should read the entire outputs (Google for StreamGobbler), and pronto!

Javadoc says:

The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.

Secondly, waitFor() your process to terminate. You then should close the input, output and error streams.

Finally destroy() your Process.

Using 'DropDownList' for the 'DropDownStyle' property of the combo box doesn't work as it changes the look and feel of the combo box. I am using Visual Studio 2019 Community Edition.

Using 'e.Handled = True' also doesn't work either as it still allows user input. Using 'False' for the 'Enabled' property of the combo box also doesn't work too because it stops the user from being able to use the combo box.

All of the "solutions" that have been proposed above are complete rubbish. What really works is this following code which restricts user input to certain keys such as up / down (for navigating through the list of all available choices in the combo box), suppressing all other key inputs:-

Private Sub ComboBox1_KeyDown(sender As Object, e As KeyEventArgs) Handles 
  ComboBox1.KeyDown
    REM The following code is executed whenever the user has pressed
    REM a key.  Added on Wednesday 1st January 2020.

    REM Determine what key the user has pressed.  Added on Wednesday
    REM 1st January 2020.
    Select Case e.KeyCode
        Case Keys.Down, Keys.Up
            REM This section is for whenever the user has pressed either
            REM the arrow down key or arrow up key.  Added on Wednesday
            REM 1st January 2020.

        Case Else
            REM This section is for whenever the user has pressed any
            REM other key.  Added on Wednesday 1st January 2020.

            REM Cancelling the key that the user has pressed.  Added on
            REM Wednesday 1st January 2020.
            e.SuppressKeyPress = True

    End Select

End Sub

Every time setColor gets hit, you are setting count = 1. You would need to define count outside of the scope of the function. Example:

var count=1;
function setColor(btn, color){
    var property = document.getElementById(btn);
    if (count == 0){
        property.style.backgroundColor = "#FFFFFF"
        count=1;        
    }
    else{
        property.style.backgroundColor = "#7FFF00"
        count=0;
    }

}

This is a solution in shell script:

apk="$apk_path"

1. Install apk

adb install "$apk"
sleep 1

2. Get package name

pkg_info=`aapt dump badging "$apk" | head -1 | awk -F " " '{print $2}'`
eval $pkg_info > /dev/null

3. Start app

pkg_name=$name
adb shell monkey -p "${pkg_name}" -c android.intent.category.LAUNCHER 1

I had a different approach. I've sub-classed a Thread class and in the constructor I've created an Event object. Then I've written custom join() method, which first sets this event and then calls a parent's version of itself.

Here is my class, I'm using for serial port communication in wxPython app:

import wx, threading, serial, Events, Queue

class PumpThread(threading.Thread):

    def __init__ (self, port, queue, parent):
        super(PumpThread, self).__init__()
        self.port = port
        self.queue = queue
        self.parent = parent

        self.serial = serial.Serial()
        self.serial.port = self.port
        self.serial.timeout = 0.5
        self.serial.baudrate = 9600
        self.serial.parity = 'N'

        self.stopRequest = threading.Event()

    def run (self):
        try:
            self.serial.open()
        except Exception, ex:
            print ("[ERROR]\tUnable to open port {}".format(self.port))
            print ("[ERROR]\t{}\n\n{}".format(ex.message, ex.traceback))
            self.stopRequest.set()
        else:
            print ("[INFO]\tListening port {}".format(self.port))
            self.serial.write("FLOW?\r")

        while not self.stopRequest.isSet():
            msg = ''
            if not self.queue.empty():
                try:
                    command = self.queue.get()
                    self.serial.write(command)
                except Queue.Empty:
                    continue

            while self.serial.inWaiting():
                char = self.serial.read(1)
                if '\r' in char and len(msg) > 1:
                    char = ''
                    #~ print('[DATA]\t{}'.format(msg))
                    event = Events.PumpDataEvent(Events.SERIALRX, wx.ID_ANY, msg)
                    wx.PostEvent(self.parent, event)
                    msg = ''
                    break
                msg += char
        self.serial.close()

    def join (self, timeout=None):
        self.stopRequest.set()
        super(PumpThread, self).join(timeout)

    def SetPort (self, serial):
        self.serial = serial

    def Write (self, msg):
        if self.serial.is_open:
            self.queue.put(msg)
        else:
            print("[ERROR]\tPort {} is not open!".format(self.port))

    def Stop(self):
        if self.isAlive():
            self.join()

The Queue is used for sending messages to the port and main loop takes responses back. I've used no serial.readline() method, because of different end-line char, and I have found the usage of io classes to be too much fuss.

if you need to do something before submitting data, you could use form's onsubmit.

<form method=post onsubmit="return doSomething()">
  <input type=text name=text1>
  <input type=submit>
</form>

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

Your images are not centered because your list items are not centered; only their text is centered. You can achieve the positioning you want by either centering the entire list or centering the images within the list.

A revised version of your code can be found at the bottom. In my revision I center both the list and the images within it.

The truth is you cannot center an element that has a position set to absolute.

But this behavior can be imitated!

Note: These instructions will work with any DOM block element, not just img.

1. Surround your image with a div or other tag (in your case a li).

   <div class="absolute-div">
     <img alt="my-image" src="#">
   </div>
   

   Note: The names given to these elements are not special.

2. Alter your css or scss to give the div absolute positioning and your image centered.

   .absolute-div {
     position: absolute;
   
     width: 100%; 
     // Range to be centered over. 
   
     // If this element's parent is the body then 100% = the window's width
   
     // Note: You can apply additional top/bottom and left/right attributes
     // i.e. - top: 200px; left: 200px;
   
     // Test for desired positioning.
   }
   
   .absolute-div img {
     width: 500px;
     // Note: Setting a width is crucial for margin: auto to work.
   
     margin: 0 auto;
   }
   

And there you have it! Your img should be centered!

Your code:

Try this out:

body_x000D_
{_x000D_
  text-align : center;_x000D_
}_x000D_
_x000D_
#slideshow_x000D_
{_x000D_
  list-style : none;_x000D_
  width      : 800px;_x000D_
  // alter to taste_x000D_
_x000D_
  margin     : 50px auto 0;_x000D_
}_x000D_
_x000D_
#slideshow li_x000D_
{_x000D_
  position : absolute;_x000D_
}_x000D_
_x000D_
#slideshow img_x000D_
{_x000D_
  border  : 1px solid #CCC;_x000D_
  padding : 4px;_x000D_
  height  : 500px;_x000D_
  width   : auto;_x000D_
  // This sets the width relative to your set height._x000D_
_x000D_
  // Setting a width is required for the margin auto attribute below. _x000D_
_x000D_
  margin  : 0 auto;_x000D_
}

<ul id="slideshow">_x000D_
    <li><img src="http://lorempixel.com/500/500/nature/" alt="Dummy 1" /></li>_x000D_
    <li><img src="http://lorempixel.com/500/500/nature/" alt="Dummy 2" /></li>_x000D_
</ul>

I hope this was helpful. Good luck!

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

Without using itertools:

In Python 3 you can use yield from to add a subset generator method to buit-in set class:

class SetWithSubset(set):
    def subsets(self):
        s1 = []
        s2 = list(self)

        def recfunc(i=0):            
            if i == len(s2):
                yield frozenset(s1)
            else:                
                yield from recfunc(i + 1)
                s1.append(s2[ i ])
                yield from recfunc(i + 1)
                s1.pop()

        yield from recfunc()

For example below snippet works as expected:

x = SetWithSubset({1,2,3,5,6})
{2,3} in x.subsets()            # True
set() in x.subsets()            # True
x in x.subsets()                # True
x|{7} in x.subsets()            # False
set([5,3]) in x.subsets()       # True - better alternative: set([5,3]) < x
len(x.subsets())                # 32

You can also define a helper function inside spec/support/

module ApiHelpers
  def json_body
    JSON.parse(response.body)
  end
end

RSpec.configure do |config| 
  config.include ApiHelpers, type: :request
end

and use json_body whenever you need to access the JSON response.

For example, inside your request spec you can use it directly

context 'when the request contains an authentication header' do
  it 'should return the user info' do
    user  = create(:user)
    get URL, headers: authenticated_header(user)

    expect(response).to have_http_status(:ok)
    expect(response.content_type).to eq('application/vnd.api+json')
    expect(json_body["data"]["attributes"]["email"]).to eq(user.email)
    expect(json_body["data"]["attributes"]["name"]).to eq(user.name)
  end
end

Use android sqlite like the server side database

Folow these steps listed below:

1. Find the Database tool window and click it like below image

2. Click the plus icon and select Android SQLite like below image

3. Connect your android device to your computer

4. Select the package you care and select the database like below image

5. Before all these steps above you must esure that you have the right permission to access the file : /data/data//database/databasefile.db

After all these steps you will see the database content like below :

Last important thing is

You must click the update icon every time where database data has been updated.

Hope this is work for you! Thank you !

For a 10 minute interval, you would

GROUP BY (DATEPART(MINUTE, [Date]) / 10)

As was already mentioned by tzup and Pieter888... to do an hour interval, just

GROUP BY DATEPART(HOUR, [Date])

You cannot move a running docker container from one host to another.

You can commit the changes in your container to an image with docker commit, move the image onto a new host, and then start a new container with docker run. This will preserve any data that your application has created inside the container.

Nb: It does not preserve data that is stored inside volumes; you need to move data volumes manually to new host.

I think you're going to need separate lines for each segment:

import numpy as np
import matplotlib.pyplot as plt

x, y = np.random.random(size=(2,10))

for i in range(0, len(x), 2):
    plt.plot(x[i:i+2], y[i:i+2], 'ro-')

plt.show()

(The numpy import is just to set up some random 2x10 sample data)

I like Clay Eclipse plugin. I've only used it with MySQL, but it claims Firebird support.

Now you must import them manually.

import 'rxjs/add/operator/retry';
import 'rxjs/add/operator/timeout';
import 'rxjs/add/operator/delay';
import 'rxjs/add/operator/map';




this.http.post(url, JSON.stringify(json), {headers: headers, timeout: 1000})

         .retry(2)

         .timeout(10000, new Error('Time out.'))

         .delay(10)

         .map((res) => res.json())
        .subscribe(
          (data) => resolve(data.json()),
          (err) => reject(err)
        );

The config file is just an XML file, you can open it by:

private static XmlDocument loadConfigDocument()
{
    XmlDocument doc = null;
    try
    {
        doc = new XmlDocument();
        doc.Load(getConfigFilePath());
        return doc;
    }
    catch (System.IO.FileNotFoundException e)
    {
        throw new Exception("No configuration file found.", e);
    }
    catch (Exception ex)
    {
        return null;
    }
}

and later retrieving values by:

    // retrieve appSettings node

    XmlNode node =  doc.SelectSingleNode("//appSettings");

I was having problems with this, maintaining the UK dd/mm/yyyy format, I initially used the answer from adeneo https://stackoverflow.com/a/18021130/243905 but that didnt work in safari for me so changed to this, which as far as I can tell works all over - using the jquery-ui datepicker, jquery validation.

if ($('[type="date"]').prop('type') !== 'date') {
    //for reloading/displaying the ISO format back into input again
    var val = $('[type="date"]').each(function () {
        var val = $(this).val();
        if (val !== undefined && val.indexOf('-') > 0) {
            var arr = val.split('-');
            $(this).val(arr[2] + '/' + arr[1] + '/' + arr[0]);
        }
    });

    //add in the datepicker
    $('[type="date"]').datepicker(datapickeroptions);

    //stops the invalid date when validated in safari
    jQuery.validator.methods["date"] = function (value, element) {
        var shortDateFormat = "dd/mm/yy";
        var res = true;
        try {
            $.datepicker.parseDate(shortDateFormat, value);
        } catch (error) {
            res = false;
        }
        return res;
    }
}

Instead of using EXISTS and COUNT just use @@ROWCOUNT:

select product, price from table1 where project = 1

IF @@ROWCOUNT = 0
BEGIN
    select product, price from table1 where customer = 2

    IF @@ROWCOUNT = 0
    select product, price from table1 where company = 3
END

Following worked for me

npm uninstall @angular-devkit/build-angular
npm install @angular-devkit/[email protected]

String[] mString = new String[] {"B", "D", "F"};

for (int j = 0; j < mString.length-1; j++) {
        List_Of_Array.remove(mString[j]);
}

credits : null

also works to disable the credits

I used a combination of the above solutions and some trial and error to come to this solution. Took me an annoying amount of time so I hope this can help someone else in the future. I also noticed that the date picker input is not at all supported by Safari...

I am using styled-components to render a transparent date picker input as shown in the image below:

const StyledInput = styled.input`
  appearance: none;
  box-sizing: border-box;
  border: 1px solid black;
  background: transparent;
  font-size: 1.5rem;
  padding: 8px;
  ::-webkit-datetime-edit-text { padding: 0 2rem; }
  ::-webkit-datetime-edit-month-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-day-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-year-field { text-transform: uppercase; }
  ::-webkit-inner-spin-button { display: none; }
  ::-webkit-calendar-picker-indicator { background: transparent;}
`

Perhaps your main function has been commented out because of e.g. preprocessing. To learn what preprocessing is doing, try gcc -C -E es3.c > es3.i then look with an editor into the generated file es3.i (and search main inside it).

First, you should always (since you are a newbie) compile with

  gcc -Wall -g -c es3.c
  gcc -Wall -g es3.o -o es3

The -Wall flag is extremely important, and you should always use it. It tells the compiler to give you (almost) all warnings. And you should always listen to the warnings, i.e. correct your source code file es3.C till you got no more warnings.

The -g flag is important also, because it asks gcc to put debugging information in the object file and the executable. Then you are able to use a debugger (like gdb) to debug your program.

To get the list of symbols in an object file or an executable, you can use nm.

Of course, I'm assuming you use a GNU/Linux system (and I invite you to use GNU/Linux if you don't use it already).

I had the same problem. I enabled vtx in bios and it didn't worked. After a doublecheck in the bios I recogniced that the bios said that you have to poweroff (and realy power off) the computer. After that it worked. Heavy Pitfall :)

The cleanest solution that I've seen is:

from distutils.util import strtobool
def string_to_bool(string):
    return bool(strtobool(str(string)))

Sure, it requires an import, but it has proper error handling and requires very little code to be written (and tested).

This function opens a URL without requiring additional user interaction.

/**
 * Open a URL in a new tab.
 */
function openUrl( url ){
  var html = HtmlService.createHtmlOutput('<html><script>'
  +'window.close = function(){window.setTimeout(function(){google.script.host.close()},9)};'
  +'var a = document.createElement("a"); a.href="'+url+'"; a.target="_blank";'
  +'if(document.createEvent){'
  +'  var event=document.createEvent("MouseEvents");'
  +'  if(navigator.userAgent.toLowerCase().indexOf("firefox")>-1){window.document.body.append(a)}'                          
  +'  event.initEvent("click",true,true); a.dispatchEvent(event);'
  +'}else{ a.click() }'
  +'close();'
  +'</script>'
  // Offer URL as clickable link in case above code fails.
  +'<body style="word-break:break-word;font-family:sans-serif;">Failed to open automatically. <a href="'+url+'" target="_blank" onclick="window.close()">Click here to proceed</a>.</body>'
  +'<script>google.script.host.setHeight(40);google.script.host.setWidth(410)</script>'
  +'</html>')
  .setWidth( 90 ).setHeight( 1 );
  SpreadsheetApp.getUi().showModalDialog( html, "Opening ..." );
}

This method works by creating a temporary dialog box, so it will not work in contexts where the UI service is not accessible, such as the script editor or a custom G Sheets formula.

If you know the key which you unset then put directly by comma separated

unset($attr['placeholder'], $attr['autocomplete']);

I've tested this for my project, it finds the max/min in O(n) time:

from django.db.models import Max

# Find the maximum value of the rating and then get the record with that rating. 
# Notice the double underscores in rating__max
max_rating = App.objects.aggregate(Max('rating'))['rating__max']
return App.objects.get(rating=max_rating)

This is guaranteed to get you one of the maximum elements efficiently, rather than sorting the whole table and getting the top (around O(n*logn)).

Another option, very late in coming, sorry:

http://www.architectshack.com/TextFileEncodingDetector.ashx

This small C#-only class uses BOMS if present, tries to auto-detect possible unicode encodings otherwise, and falls back if none of the Unicode encodings is possible or likely.

It sounds like UTF8Checker referenced above does something similar, but I think this is slightly broader in scope - instead of just UTF8, it also checks for other possible Unicode encodings (UTF-16 LE or BE) that might be missing a BOM.

Hope this helps someone!

You can take a look on this solution:

Centering horizontally and vertically an image in a box

<style type="text/css">

my issue (fatal: The remote end hung up unexpectedly) has been resolved by checking repository permission and owner.

git repository files owner must be that user you want push/pull/clone with it.

If you are using java8 :

java.time.Year.of(year).isLeap()

Java implementation of above method:

public static boolean isLeap(long year) {
        return ((year & 3) == 0) && ((year % 100) != 0 || (year % 400) == 0);
    }

One more important thing to realise: if you see iso-8859-1, it probably refers to Windows-1252 rather than ISO/IEC 8859-1. They differ in the range 0x80–0x9F, where ISO 8859-1 has the C1 control codes, and Windows-1252 has useful visible characters instead.

For example, ISO 8859-1 has 0x85 as a control character (in Unicode, U+0085, ``), while Windows-1252 has a horizontal ellipsis (in Unicode, U+2026 HORIZONTAL ELLIPSIS, …).

The WHATWG Encoding spec (as used by HTML) expressly declares iso-8859-1 to be a label for windows-1252, and web browsers do not support ISO 8859-1 in any way: the HTML spec says that all encodings in the Encoding spec must be supported, and no more.

Also of interest, HTML numeric character references essentially use Windows-1252 for 8-bit values rather than Unicode code points; per https://html.spec.whatwg.org/#numeric-character-reference-end-state, … will produce U+2026 rather than U+0085.

What you need to do is :

1) Add a key inside of web.config, depending upon the production or stage server like below

<add key="HttpsServer" value="stage"/>
             or
<add key="HttpsServer" value="prod"/>

2) Inside your Global.asax file add below method.

void Application_BeginRequest(Object sender, EventArgs e)
{
    //if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "prod")
    if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "stage")
    {
        if (!HttpContext.Current.Request.IsSecureConnection)
        {
            if (!Request.Url.GetLeftPart(UriPartial.Authority).Contains("www"))
            {
                HttpContext.Current.Response.Redirect(
                    Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://www."), true);
            }
            else
            {
                HttpContext.Current.Response.Redirect(
                    Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://"), true);
            }
        }
    }
}

Here is how I do this: http://jsfiddle.net/Zz7Wq/2/

I use a background instead of after and use my H1 or H2 to cover the background. Not quite your method above but does work well for me.

CSS

.title-box { background: #fff url('images/bar-orange.jpg') repeat-x left; text-align: left; margin-bottom: 20px;}
.title-box h1 { color: #000; background-color: #fff; display: inline; padding: 0 50px 0 50px; }

HTML

<div class="title-box"><h1>Title can go here</h1></div>
<div class="title-box"><h1>Title can go here this one is really really long</h1></div>

It's also a common convention to use with the first argument of the test method from Kernel#test

irb(main):001:0> test ?d, "/dev" # directory exists?
=> true
irb(main):002:0> test ?-, "/etc/hosts", "/etc/hosts" # are the files identical
=> true

as seen in this question here

All DECLAREs need to be at the top. ie.

delimiter //

CREATE TRIGGER pgl_new_user 
AFTER INSERT ON users FOR EACH ROW
BEGIN
    DECLARE m_user_team_id integer;
    DECLARE m_projects_id integer;
    DECLARE cur CURSOR FOR SELECT project_id FROM user_team_project_relationships WHERE user_team_id = m_user_team_id;

    SET @m_user_team_id := (SELECT id FROM user_teams WHERE name = "pgl_reporters");

    OPEN cur;
        ins_loop: LOOP
            FETCH cur INTO m_projects_id;
            IF done THEN
                LEAVE ins_loop;
            END IF;
            INSERT INTO users_projects (user_id, project_id, created_at, updated_at, project_access) 
            VALUES (NEW.id, m_projects_id, now(), now(), 20);
        END LOOP;
    CLOSE cur;
END//

I've implemented this very simple func:

func convap (text : String) -> String {
    return text.stringByReplacingOccurrencesOfString("'", withString: "''")
}

So you can write:

let sqlQuery = "INSERT INTO myTable (Field1, Field2) VALUES ('\(convap(value1))','\(convap(value2)')

All exceptions must be checked exceptions.

1. Unchecked exceptions are unrestricted gotos. And unrestricted gotos are considered a bad thing.

2. Unchecked exceptions break encapsulation. To process them correctly, all the functions in the call tree between the thrower and the catcher must be known to avoid bugs.

3. Exceptions are errors in the function that throws them but not errors in the function that processes them. The purpose of exceptions is to give the program a second chance by deferring the decision of whether it's an error or not to another context. It's only in the other context can the correct decision be made.

You could try with simple 3 dots. refer to the code in perl below

$a =~ m /.../ #where $a is your string

It depends upon what you mean by split. If you want to iterate over words in a line, which is in a variable, you can just iterate. For example, let's say the variable line is this is a line. Then you can do this:

for word in $line; do echo $word; done

This will print:

this
is
a
line

for .. in $var splits $var using the values in $IFS, the default value of which means "split blanks and newlines".

If you want to read lines from user or a file, you can do something like:

cat $filename | while read line
do
    echo "Processing new line" >/dev/tty
    for word in $line
    do
        echo $word
    done
done

For anything else, you need to be more explicit and define your question in more detail.

Note: Edited to remove bashism, but I still kept cat $filename | ... because I like it more than redirection.

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

Try this :

$('#input_id :selected').val(); //for getting value from selected option
$('#input_id :selected').text(); //for getting text from selected option

You can use TreeSet class in java.util.*. It is working like Binary search tree, so it is already sorted. TreeSet class implements Iterable, Collection and Set interfaces. You can traverse through the tree with iterator like a set.

TreeSet<String> treeSet = new TreeSet<String>();
Iterator<String> it  = treeSet.Iterator();
while(it.hasNext()){
...
}

You can check, Java Doc and some other .

Got stupid error. So post here, if anyone find it useful

1. [-\._] - means hyphen, dot and underscore
2. [\.-_] - means all signs in range from dot to underscore

The backwards compatible version (IE9+) is

var parent = document.querySelector(selector);
Array.prototype.forEach.call(parent.children, function(child, index){
  // Do stuff
});

The es6 way is

const parent = document.querySelector(selector);
Array.from(parent.children).forEach((child, index) => {
  // Do stuff
});

You might need to install SQL Server 2008 SP3.

SQL Server 2008 Service Pack 3

SQL Server 2012 Configuration Manager WMI Error – Remote Procedure call failed [0x800706be]

I had a similar issue and I tried all the workarounds above but none of them worked for me ( I was using special characters (like '@' symbol) in my password and I also needed to add domain name).

Apart from that I was bit apprehensive to add my password as plain text. It turned-out the easiest solution to overcome all these challenges was to use some sort of reverse proxy (like Fiddler).

I have already detailed the configuration steps in this answer in SO.

I had added another project to my workspace and was trying to reference an activity from it in the manifest file, and I was getting this error. The problem is I was referencing the library incorrectly. This is how I fixed the problem:

• Right click on project
• Select Properties
• Click on Android on left menu
• Click on Add
• Please select a Library Project

The jar went into Android Dependencies folder and this error was fixed.

Using various cheats from the web, I came to this solution:

int[] count = new int[1];
final int CHUNK_SIZE = 500;
Map<Integer, List<Long>> chunkedUsers = users.stream().collect( Collectors.groupingBy( 
    user -> {
        count[0]++;
        return Math.floorDiv( count[0], CHUNK_SIZE );
    } )
);

We use count to mimic a normal collection index.
Then, we group the collection elements in buckets, using the algebraic quotient as bucket number.
The final map contains as key the bucket number, as value the bucket itself.

You can then easily do an operation on each of the buckets with:

chunkedUsers.values().forEach( ... );

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

In addition to the rest, there's currently a draft (stage-2 proposal) on ECMA Proposals that introduces static public fields in classes. (private fields were considered)

Using the example from the proposal, the proposed static syntax will look like this:

class CustomDate {
  // ...
  static epoch = new CustomDate(0);
}

and be equivalent to the following which others have highlighted:

class CustomDate {
  // ...
}
CustomDate.epoch = new CustomDate(0);

You can then access it via CustomDate.epoch.

You can keep track of the new proposal in proposal-static-class-features.

Currently, babel supports this feature with the transform class properties plugin which you can use. Additionally, though still in progress, V8 is implementing it.

You could prove to yourself that there is no other difference by trying to define a function in a struct. I remember even my college professor who was teaching about structs and classes in C++ was surprised to learn this (after being corrected by a student). I believe it, though. It was kind of amusing. The professor kept saying what the differences were and the student kept saying "actually you can do that in a struct too". Finally the prof. asked "OK, what is the difference" and the student informed him that the only difference was the default accessibility of members.

A quick Google search suggests that POD stands for "Plain Old Data".

Simple Answer:

SELECT distinct(sal)
FROM emp
ORDER BY sal DESC
LIMIT 1, 1;

You will get only the second max salary.

And if you need any 3rd or 4th or Nth value you can increase the first value followed by LIMIT (n-1) ie. for 4th salary : LIMIT 3, 1;

Use round()

$float_val = 4.5;

echo round($float_val);

You can also set param for precision and rounding mode, for more info

Update (According to your updated question):

$float_val = 1.0000124668092E+14;
printf('%.0f', $float_val / 1E+14); //Output Rounds Of To 1000012466809201

Does it matter which is faster, if they don't do the same thing? Comparing the performance of statements with different meaning seems like a bad idea.

is tells you if the object implements ClassA anywhere in its type heirarchy. GetType() tells you about the most-derived type.

Not the same thing.

You can simply solve this problem using usort() with callback function. No need to write any custom function.

$your_date_field_name = 'datetime';
usort($your_given_array_name, function ($a, $b) use (&$your_date_field_name) {
    return strtotime($a[$your_date_field_name]) - strtotime($b[$your_date_field_name]);
});

Another way could be :

System.Reflection.Assembly.GetAssembly(type).Location

IF the file you are trying to get is the assembly location for a type. But if the files are relative to the assembly location then you can use this with System.IO namespace to get the exact path of the file.

Use the span tag with display:inline-block css attached to it. You can then use CSS and manipulate it like a div in lots of ways but if you don't include a width or height it expands and retracts based on its content.

Hope that helps.

absolute positioning is evil... this solution doesn't take into account window size. If you resize the browser window, your div will be out of place!

PHP 8 or newer:

Use the str_starts_with function:

str_starts_with('http://www.google.com', 'http')

PHP 7 or older:

Use the substr function to return a part of a string.

substr( $string_n, 0, 4 ) === "http"

If you're trying to make sure it's not another protocol. I'd use http:// instead, since https would also match, and other things such as http-protocol.com.

substr( $string_n, 0, 7 ) === "http://"

And in general:

substr($string, 0, strlen($query)) === $query

you can use this for 0.9.0.0. version kafka

C# 9 (released with .NET 5) includes the logical patterns and, or and not, which allows us to write this more elegantly:

if (child is not IContainer) { ... }

Likewise, this pattern can be used to check for null:

if (child is not null) { ... }

Strangely enough,

package main

func main () {
    var sessions = map[string] chan int{};
    delete(sessions, "moo");
}

seems to work. This seems a poor use of resources though!

Another way is to check for existence and use the value itself:

package main

func main () {
    var sessions = map[string] chan int{};
    sessions["moo"] = make (chan int);
    _, ok := sessions["moo"];
    if ok {
        delete(sessions, "moo");
    }
}

Both are different ways of defining a function. The difference is how the browser interprets and loads them into an execution context.

The first case is of function expressions which loads only when the interpreter reaches that line of code. So if you do it like the following, you will get an error that the functionOne is not a function.

functionOne();
var functionOne = function() {
    // Some code
};

The reason is that on the first line no value is assigned to functionOne, and hence it is undefined. We are trying to call it as a function, and hence we are getting an error.

On the second line we are assigning the reference of an anonymous function to functionOne.

The second case is of function declarations that loads before any code is executed. So if you do like the following you won't get any error as the declaration loads before code execution.

functionOne();
function functionOne() {
   // Some code
}

On Unix systems, for several projects, I added these lines into the CMakeLists.txt and it was compiling successfully because base (/usr/include) and local includes (/usr/local/include) go into separated directories:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -I/usr/local/include -L/usr/local/lib")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/local/include")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L/usr/local/lib")

It appends the correct directory, including paths for the C and C++ compiler flags and the correct directory path for the linker flags.

Note: C++ compiler (c++) doesn't support -L, so we have to use CMAKE_EXE_LINKER_FLAGS

Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData.

Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently.

So, answering your questions:

• The difference is not about the compression, but serialization (See this page)
• Like shown in the manual page, you may wanna use it to restore a certain object with a different name, for instance.
• You may readRDS() and save(), or load() and saveRDS() selectively.

The answer above is absolutely correct. Here is a Turbo C++ version of it.

#include <iomanip.h>
#include <iostream.h>

void main()
{
    double num1 = 3.12345678;
    cout << setiosflags(fixed) << setiosflags(showpoint);
    cout << setprecision(2);
    cout << num1 << endl;
}

For fixed and showpoint, I think the setiosflags function should be used.

Found the answer here - http://mytechead.wordpress.com/2014/01/30/android-create-a-file-and-write-to-external-storage/

It says,

/**

* Method to check if user has permissions to write on external storage or not

*/

public static boolean canWriteOnExternalStorage() {
   // get the state of your external storage
   String state = Environment.getExternalStorageState();
   if (Environment.MEDIA_MOUNTED.equals(state)) {
    // if storage is mounted return true
      Log.v("sTag", "Yes, can write to external storage.");
      return true;
   }
   return false;
}

and then let’s use this code to actually write to the external storage:

// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + "/your-dir-name/");
// create this directory if not already created
dir.mkdir();
// create the file in which we will write the contents
File file = new File(dir, "My-File-Name.txt");
FileOutputStream os = outStream = new FileOutputStream(file);
String data = "This is the content of my file";
os.write(data.getBytes());
os.close();

And this is it. If now you visit your /sdcard/your-dir-name/ folder you will see a file named - My-File-Name.txt with the content as specified in the code.

PS:- You need the following permission -

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

If you're looking for an alternative to reflections I'd like to recommend Panda Utilities - AnnotationsScanner. It's a Guava-free (Guava has ~3MB, Panda Utilities has ~200kb) scanner based on the reflections library source code.

It's also dedicated for future-based searches. If you'd like to scan multiple times included sources or even provide an API, which allows someone scanning current classpath, AnnotationsScannerProcess caches all fetched ClassFiles, so it's really fast.

Simple example of AnnotationsScanner usage:

AnnotationsScanner scanner = AnnotationsScanner.createScanner()
        .includeSources(ExampleApplication.class)
        .build();

AnnotationsScannerProcess process = scanner.createWorker()
        .addDefaultProjectFilters("net.dzikoysk")
        .fetch();

Set<Class<?>> classes = process.createSelector()
        .selectTypesAnnotatedWith(AnnotationTest.class);

This is what I did. Most tooltip scripts require you to execute a function that stores the tooltips. This is a jQuery example:

$.when($('*').filter(function() {
   return $(this).css('text-overflow') == 'ellipsis';
}).each(function() {
   if (this.offsetWidth < this.scrollWidth && !$(this).attr('title')) {
      $(this).attr('title', $(this).text());
   }
})).done(function(){ 
   setupTooltip();
});

If you didn't want to check for ellipsis css, you could simplify like:

$.when($('*').filter(function() {
   return (this.offsetWidth < this.scrollWidth && !$(this).attr('title'));
}).each(function() {
   $(this).attr('title', $(this).text());
})).done(function(){ 
   setupTooltip();
});

I have the "when" around it, so that the "setupTooltip" function doesn't execute until all titles have been updated. Replace the "setupTooltip", with your tooltip function and the * with the elements you want to check. * will go through them all if you leave it.

If you simply want to just update the title attributes with the browsers tooltip, you can simplify like:

$('*').filter(function() {
   return $(this).css('text-overflow') == 'ellipsis';
}).each(function() {
   if (this.offsetWidth < this.scrollWidth && !$(this).attr('title')) {
      $(this).attr('title', $(this).text());
   }
});

Or without check for ellipsis:

$.when($('*').filter(function() {
   return (this.offsetWidth < this.scrollWidth && !$(this).attr('title'));
}).each(function() {
   $(this).attr('title', $(this).text());
});

I had the same issue today recently installing VS2015 Community Edition Update 1.

I fixed the problem by just adding the "SQL Server Data Tools" from the VS2015 setup installer... When I ran the installer the first time I selected the "Custom" installation type instead of the "Default". I wanted to see what install options were available but not select anything different than what was already ticked. My assumption was that whatever was already ticked was essentially the default install. But its not.

Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.

import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest

Only downside is that read_html() doesn't preserve hyperlinks.

To do this you want to loop through each row of your query results and use this info for each of your drop down's options. You should be able to adjust the code below fairly easily to meet your needs.

// Assume $db is a PDO object
$query = $db->query("YOUR QUERY HERE"); // Run your query

echo '<select name="DROP DOWN NAME">'; // Open your drop down box

// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
   echo '<option value="'.$row['something'].'">'.$row['something'].'</option>';
}

echo '</select>';// Close your drop down box

Node has its own built in GUI debugger as of version 6.3 (using Chrome's DevTools)

Simply pass the inspector flag and you'll be provided with a URL to the inspector:

node --inspect server.js

You can also break on the first line by passing --inspect-brk instead.

Here's how I test javascript using PhantomJS and Django:

mobile/test_no_js_errors.js:

var page = require('webpage').create(),
    system = require('system'),
    url = system.args[1],
    status_code;

page.onError = function (msg, trace) {
    console.log(msg);
    trace.forEach(function(item) {
        console.log('  ', item.file, ':', item.line);
    });
};

page.onResourceReceived = function(resource) {
    if (resource.url == url) {
        status_code = resource.status;
    }
};

page.open(url, function (status) {
    if (status == "fail" || status_code != 200) {
        console.log("Error: " + status_code + " for url: " + url);
        phantom.exit(1);
    }
    phantom.exit(0);
});

mobile/tests.py:

import subprocess
from django.test import LiveServerTestCase

class MobileTest(LiveServerTestCase):
    def test_mobile_js(self):
        args = ["phantomjs", "mobile/test_no_js_errors.js", self.live_server_url]
        result = subprocess.check_output(args)
        self.assertEqual(result, "")  # No result means no error

Run tests:

manage.py test mobile

In Python 2.x this is not guaranteed as it is possible for True and False to be reassigned. However, even if this happens, boolean True and boolean False are still properly returned for comparisons.

In Python 3.x True and False are keywords and will always be equal to 1 and 0.

Under normal circumstances in Python 2, and always in Python 3:

False object is of type bool which is a subclass of int:

object
   |
 int
   |
 bool

It is the only reason why in your example, ['zero', 'one'][False] does work. It would not work with an object which is not a subclass of integer, because list indexing only works with integers, or objects that define a __index__ method (thanks mark-dickinson).

Edit:

It is true of the current python version, and of that of Python 3. The docs for python 2 and the docs for Python 3 both say:

There are two types of integers: [...] Integers (int) [...] Booleans (bool)

and in the boolean subsection:

Booleans: These represent the truth values False and True [...] Boolean values behave like the values 0 and 1, respectively, in almost all contexts, the exception being that when converted to a string, the strings "False" or "True" are returned, respectively.

There is also, for Python 2:

In numeric contexts (for example when used as the argument to an arithmetic operator), they [False and True] behave like the integers 0 and 1, respectively.

So booleans are explicitly considered as integers in Python 2 and 3.

So you're safe until Python 4 comes along. ;-)

@balalakshmi mentioned about the correct authentication settings. Authentication is only half of the problem, the other half is authorization.

If you're using Forms Authentication and standard controls like <asp:Login> there are a couple of things you'll need to do to ensure that only your authenticated users can access secured pages.

In web.config, under the <system.web> section you'll need to disable anonymous access by default:

<authorization>
 <deny users="?" />
</authorization>

Any pages that will be accessed anonymously (such as the Login.aspx page itself) will need to have an override that re-allows anonymous access. This requires a <location> element and must be located at the <configuration> level (outside the <system.web> section), like this:

<!-- Anonymous files -->
<location path="Login.aspx">
 <system.web>
  <authorization>
   <allow users="*" />
  </authorization>
 </system.web>
</location>

Note that you'll also need to allow anonymous access to any style sheets or scripts that are used by the anonymous pages:

<!-- Anonymous folders -->
<location path="styles">
 <system.web>
  <authorization>
   <allow users="*" />
  </authorization>
 </system.web>
</location>

Be aware that the location's path attribute is relative to the web.config folder and cannot have a ~/ prefix, unlike most other path-type configuration attributes.

I had the same problem. My .sql file was 830 MB and the phpMyAdmin import size allowed was 50MB (just as shown in the screenshot). When I zipped the file to .zip its size became about 80 MB. Then I zipped it to bzip2 format, and I was amazed to see that the file size was compressed to just 12MB (from 830MB to 12MB!!!). As phpMyAdmin allows three compression types i.e. .zip , .gzip and .bzip2 , therefore I uploaded the compressed bzip2 file and viola.... it was imported to the database!!! So by using the right compression, I was able to import a 830MB .sql file into phpMyAdmin.

NOTE: phpMyAdmin import page clearly instructs that the compressed filename should be like filename.sql.bz2 . It should not be like filename.bz2 .

NOTE 2: You can compress your .sql file to bzip2 compressed file using 7-Zip software. cPanel also has an option to compress a file to bzip2 format.

If you have issue with writing into an existing xls file because it is already created you need to put checking part like below:

PATH='filename.xlsx'
if os.path.isfile(PATH):
    print "File exists and will be overwrite NOW"
else:
    print "The file is missing, new one is created"

... and here part with the data you want to add

The correct syntax is:

import sampleModule = require('modulename');

or

import * as sampleModule from 'modulename';

Then compile your TypeScript with --module commonjs.

If the package doesn't come with an index.d.ts file and its package.json doesn't have a "typings" property, tsc will bark that it doesn't know what 'modulename' refers to. For this purpose you need to find a .d.ts file for it on http://definitelytyped.org/, or write one yourself.

If you are writing code for Node.js you will also want the node.d.ts file from http://definitelytyped.org/.

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

If you still like to use indentation, do it after opening the <?php tag, like so:

<textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"><?php // <--- newline
    if($siteLink_val) echo $siteLink_val; // <--- indented, newline
?></textarea>

This is how I solved this annoying issue:

I changed the PATH variable as @sagar suggested in his 2nd option, but still I got different PATH value than I expected.

Eventually I found out that it was the EnvInject plugin that replaced my PATH variable!

So I could either uninstall EnvInject or just use it to inject the PATH variable.

As many of our Jenkins jobs use that plugin, I didn't want to uninstall it...

So I created a file: environment_variables.properties under my Jenkins home directory.

This file contained the path environment value that I needed: PATH=$PATH:/usr/local/git/bin/.

From the Jenkins web interface: Manage Jenkins -> Configure System. In that screen - I ticked the Prepare jobs environment option, and in the Properties File Path field I entered the path to my file: /var/lib/jenkins/environment_variables.properties.

This way every Jenkins job we have receive whatever variables I put in this environment_variables.properties file.

Use sapply and is.na<-

> dat <- data.frame(a=c(1, Inf), b=c(Inf, 3), d=c("a","b"))
> is.na(dat) <- sapply(dat, is.infinite)
> dat
   a  b d
1  1 NA a
2 NA  3 b

Or you can use (giving credit to @mnel, whose edit this is),

> is.na(dat) <- do.call(cbind,lapply(dat, is.infinite))

which is significantly faster.

If you can use PowerShell on Windows you just need :

Get-Process -Id (Get-NetTCPConnection -LocalPort "8080").OwningProcess | Stop-Process

You could drop any indexes on the table, then do your insert, and then recreate the indexes.

If you think map() as an iteration(one level for loop), flatmap() is a two-level iteration(like a nested for loop). (Enter each iterated element foo, and do foo.getBarList() and iterate in that barList again)

map(): take a stream, do something to every element, collect the single result of every process, output another stream. The definition of "do something function" is implicit. If the processment of any element results in null, null is used to compose the final stream. So, the number of elements in the resulting stream will be equal to number of input stream.

flatmap(): take a stream of elements/streams and a function(explicit definition), apply the function to each element of each stream, and collect all the intermediate resulting stream to be a greater stream("flattening"). If the processment of any element results in null, empty stream is provided to the final step of "flattening". The number of elements in the resulting stream, is the total of all participating elements in all inputs, if the input is several streams.

Here is settings.xml --> C:\maven\conf\settings.xml

I like the answer but I think it would be better that you create a global scope function that will allow you to set the scope variable needed.

So in the globalController create

$scope.setScopeVariable = function(variable, value){
    $scope[variable] = value;
}

and then in your html file call it

{{setScopeVariable('myVar', 'whatever')}}

This will then allow you to use $scope.myVar in your respective controller

Congratulations, you've hit my favorite pet peeve with JDBC: Date class handling.

Basically databases usually support at least three forms of datetime fields which are date, time and timestamp. Each of these have a corresponding class in JDBC and each of them extend java.util.Date. Quick semantics of each of these three are the following:

• java.sql.Date corresponds to SQL DATE which means it stores years, months and days while hour, minute, second and millisecond are ignored. Additionally sql.Date isn't tied to timezones.
• java.sql.Time corresponds to SQL TIME and as should be obvious, only contains information about hour, minutes, seconds and milliseconds.
• java.sql.Timestamp corresponds to SQL TIMESTAMP which is exact date to the nanosecond (note that util.Date only supports milliseconds!) with customizable precision.

One of the most common bugs when using JDBC drivers in relation to these three types is that the types are handled incorrectly. This means that sql.Date is timezone specific, sql.Time contains current year, month and day et cetera et cetera.

Finally: Which one to use?

Depends on the SQL type of the field, really. PreparedStatement has setters for all three values, #setDate() being the one for sql.Date, #setTime() for sql.Time and #setTimestamp() for sql.Timestamp.

Do note that if you use ps.setObject(fieldIndex, utilDateObject); you can actually give a normal util.Date to most JDBC drivers which will happily devour it as if it was of the correct type but when you request the data afterwards, you may notice that you're actually missing stuff.

I'm really saying that none of the Dates should be used at all.

What I am saying that save the milliseconds/nanoseconds as plain longs and convert them to whatever objects you are using (obligatory joda-time plug). One hacky way which can be done is to store the date component as one long and time component as another, for example right now would be 20100221 and 154536123. These magic numbers can be used in SQL queries and will be portable from database to another and will let you avoid this part of JDBC/Java Date API:s entirely.

I had a similar problem and found that if you remove the size definition, it works for some reason.

Remove:

<size
    android:width="60dp"
    android:height="40dp" />

from the shape.

Let me know if this works!

I'm running Qt 5.5 under Windows and the default constructor of QDir appears to pick up the current working directory, not the application directory.

I'm not sure if the getenv PWD will work cross-platform and I think it is set to the current working directory when the shell launched the application and doesn't include any working directory changes done by the app itself (which might be why the OP is seeing this behavior).

So I thought I'd add some other ways that should give you the current working directory (not the application's binary location):

// using where a relative filename will end up
QFileInfo fi("temp");
cout << fi.absolutePath() << endl;

// explicitly using the relative name of the current working directory
QDir dir(".");
cout << dir.absolutePath() << endl;

A quick and easy solution for interactive work is to copy-and-paste the text by loading the data from the clipboard.

Select the content of the string with your mouse:

In the Python shell use read_clipboard()

>>> pd.read_clipboard()
  col1;col2;col3
0       1;4.4;99
1      2;4.5;200
2       3;4.7;65
3      4;3.2;140

Use the appropriate separator:

>>> pd.read_clipboard(sep=';')
   col1  col2  col3
0     1   4.4    99
1     2   4.5   200
2     3   4.7    65
3     4   3.2   140

>>> df = pd.read_clipboard(sep=';') # save to dataframe

C:\\Users\\expoperialed\\Desktop\\Python This syntax worked for me.

Though this does not directly answer the question, but I think it is a good alternative to avoid the question altogether.

To avoid all the autoload_paths or eager_load_paths hassle, create a "lib" or a "misc" directory under "app" directory. Place codes as you would normally do in there, and Rails will load files just like how it will load (and reload) model files.

AsyncTask have four methods..

onPreExecute  -- for doing something before calling background task in Async

doInBackground  -- operation/Task to do in Background

onProgressUpdate  -- it is for progress Update

onPostExecute  -- this method calls after asyncTask return from doInBackground.

you can call your work on onPostExecute() it calls after returning from doInBackground()

onPostExecute is what you need to Implement.

java.io.IOException in Netty means your game server tries to send data to a client, but that client has closed connection to your server.

And that exception is not the only one! There're several others. See BadClientSilencer in Xitrum. I had to add that to prevent those errors from messing my log file.

What the provided links to comparisons/animations do not consider is when the amount of data exceed available memory --- at which point the number of passes over the data, i.e. I/O-costs, dominate the runtime. If you need to do that, read up on "external sorting" which usually cover variants of merge- and heap sorts.

http://corte.si/posts/code/visualisingsorting/index.html and http://corte.si/posts/code/timsort/index.html also have some cool images comparing various sorting algorithms.

Description

Assuming i understand your question.

You can get the selected row using the DataGridView.SelectedRows Collection. If your DataGridView allows only one selected, have a look at my sample.

DataGridView.SelectedRows Gets the collection of rows selected by the user.

Sample

if (dataGridView1.SelectedRows.Count != 0)
{
    DataGridViewRow row = this.dataGridView1.SelectedRows[0];
    row.Cells["ColumnName"].Value
}

For C99 there is P99_DECLARE_ENUM in P99 that lets you simply declare enum like this:

P99_DECLARE_ENUM(color, red, green, blue);

and then use color_getname(A) to obtain a string with the color name.

There are a plethora of ways in which this can be done. The problem is how to make R aware of the locations of the variables you wish to divide.

Assuming

d <- read.table(text = "263807.0    1582
196190.5    1016
586689.0    3479
")
names(d) <- c("min", "count2.freq")
> d
       min count2.freq
1 263807.0        1582
2 196190.5        1016
3 586689.0        3479

My preferred way

To add the desired division as a third variable I would use transform()

> d <- transform(d, new = min / count2.freq)
> d
       min count2.freq      new
1 263807.0        1582 166.7554
2 196190.5        1016 193.1009
3 586689.0        3479 168.6373

The basic R way

If doing this in a function (i.e. you are programming) then best to avoid the sugar shown above and index. In that case any of these would do what you want

## 1. via `[` and character indexes
d[, "new"] <- d[, "min"] / d[, "count2.freq"]

## 2. via `[` with numeric indices
d[, 3] <- d[, 1] / d[, 2]

## 3. via `$`
d$new <- d$min / d$count2.freq

All of these can be used at the prompt too, but which is easier to read:

d <- transform(d, new = min / count2.freq)

or

d$new <- d$min / d$count2.freq ## or any of the above examples

Hopefully you think like I do and the first version is better ;-)

The reason we don't use the syntactic sugar of tranform() et al when programming is because of how they do their evaluation (look for the named variables). At the top level (at the prompt, working interactively) transform() et al work just fine. But buried in function calls or within a call to one of the apply() family of functions they can and often do break.

Likewise, be careful using numeric indices (## 2. above); if you change the ordering of your data, you will select the wrong variables.

The preferred way if you don't need replacement

If you are just wanting to do the division (rather than insert the result back into the data frame, then use with(), which allows us to isolate the simple expression you wish to evaluate

> with(d, min / count2.freq)
[1] 166.7554 193.1009 168.6373

This is again much cleaner code than the equivalent

> d$min / d$count2.freq
[1] 166.7554 193.1009 168.6373

as it explicitly states that "using d, execute the code min / count2.freq. Your preference may be different to mine, so I have shown all options.

Python, like most modern programming languages, does not support "goto". Instead, you must use control functions. There are essentially two ways to do this.

1. Loops

An example of how you could do exactly what your SmallBasic example does is as follows:

while True :
    print "Poo"

It's that simple.

2. Recursion

def the_func() :
   print "Poo"
   the_func()

the_func()

Note on Recursion: Only do this if you have a specific number of times you want to go back to the beginning (in which case add a case when the recursion should stop). It is a bad idea to do an infinite recursion like I define above, because you will eventually run out of memory!

Edited to Answer Question More Specifically

#Alan's Toolkit for conversions

invalid_input = True
def start() :
    print ("Welcome to the converter toolkit made by Alan.")
    op = input ("Please input what operation you wish to perform. 1 for Fahrenheit to Celsius, 2 for meters to centimetres and 3 for megabytes to gigabytes")
    if op == "1":
        #stuff
        invalid_input = False # Set to False because input was valid


    elif op == "2":
        #stuff
        invalid_input = False # Set to False because input was valid
    elif op == "3": # you still have this as "if"; I would recommend keeping it as elif
        #stuff
        invalid_input = False # Set to False because input was valid
    else:
        print ("Sorry, that was an invalid command!")

while invalid_input : # this will loop until invalid_input is set to be True
    start()

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

Try this solution.

$mainModelData = mainModel::where('column', $value)
    ->join('relationModal', 'main_table_name.relation_table_column', '=', 'relation_table.id')
    ->orderBy('relation_table.title', 'ASC')
    ->with(['relationModal' => function ($q) {
        $q->where('column', 'value');
    }])->get();

Example:

$user = User::where('city', 'kullu')
    ->join('salaries', 'users.id', '=', 'salaries.user_id')
    ->orderBy('salaries.amount', 'ASC')
    ->with(['salaries' => function ($q) {
        $q->where('amount', '>', '500000');
    }])->get();

You can change the column name in join() as per your database structure.

The best practice would be to create a module separately which has only one method whose task we be to give a logger handler to the the calling method. Save this file as m_logger.py

import logger, logging

def getlogger():
    # logger
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.DEBUG)
    # create console handler and set level to debug
    #ch = logging.StreamHandler()
    ch = logging.FileHandler(r'log.txt')
    ch.setLevel(logging.DEBUG)
    # create formatter
    formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')
    # add formatter to ch
    ch.setFormatter(formatter)
    # add ch to logger
    logger.addHandler(ch)
    return logger

Now call the getlogger() method whenever logger handler is needed.

from m_logger import getlogger
logger = getlogger()
logger.info('My mssg')

I wrote with parameters that are predefined

They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:

Alter Procedure [Test]
    @StartDate AS varchar(6) = NULL, 
    @EndDate AS varchar(6) = NULL
AS
...

NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.

Now you can call it without passing any arguments e.g. exec dbo.TEST

You need to be in project folder, if you are in src or public you have to come out of those folders. Suppose your react-project name is 'hello-react' then cd hello-react

public class DownloadManager {

    static String urls = "[WEBSITE NAME]";

    public static void main(String[] args) throws IOException{
        URL url = verify(urls);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        InputStream in = null;
        String filename = url.getFile();
        filename = filename.substring(filename.lastIndexOf('/') + 1);
        FileOutputStream out = new FileOutputStream("C:\\Java2_programiranje/Network/DownloadTest1/Project/Output" + File.separator + filename);
        in = connection.getInputStream();
        int read = -1;
        byte[] buffer = new byte[4096];
        while((read = in.read(buffer)) != -1){
            out.write(buffer, 0, read);
            System.out.println("[SYSTEM/INFO]: Downloading file...");
        }
        in.close();
        out.close();
        System.out.println("[SYSTEM/INFO]: File Downloaded!");
    }
    private static URL verify(String url){
        if(!url.toLowerCase().startsWith("http://")) {
            return null;
        }
        URL verifyUrl = null;

        try{
            verifyUrl = new URL(url);
        }catch(Exception e){
            e.printStackTrace();
        }
        return verifyUrl;
    }
}

If you just want the node closest to the text you're searching for, you could use this:

$('*:contains("my text"):last');

This will even work if your HTML looks like this:

<p> blah blah <strong>my <em>text</em></strong></p>

Using the above selector will find the <strong> tag, since that's the last tag which contains that entire string.

Why not just use atoi? For example:

char myarray[4] = {'-','1','2','3'};

int i = atoi(myarray);

printf("%d\n", i);

Gives me, as expected:

-123

Update: why not - the character array is not null terminated. Doh!

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

Set LDFLAGS and CFLAGS when you run make:

$ LDFLAGS="-L/home/me/local/lib" CFLAGS="-I/home/me/local/include" make

If you don't want to do that a gazillion times, export these in your .bashrc (or your shell equivalent). Also set LD_LIBRARY_PATH to include /home/me/local/lib:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/local/lib

I got the same error i created the app with create-react-app but in /public/index.html also added matrialize script but there was to connection with "root" so i added

<div id="root"></div>

just before

<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/ materialize.min.js"></script>

And it worked for me .

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

Here is Something I did

var ImgRotator = {
    angle:parseInt(45),
    image:{},
    src:"",
    canvasID:"",
    intervalMS:parseInt(500),
    jump:parseInt(5),
    start_action:function(canvasID, imgSrc, interval, jumgAngle){
        ImgRotator.jump = jumgAngle;
        ImgRotator.intervalMS = interval;
        ImgRotator.canvasID = canvasID;
        ImgRotator.src = imgSrc ;
        var image = new Image();
        var canvas = document.getElementById(ImgRotator.canvasID);
        image.onload = function() {
            ImgRotator.image = image;
            canvas.height = canvas.width = Math.sqrt( image.width* image.width+image.height*image.height);
            window.setInterval(ImgRotator.keepRotating,ImgRotator.intervalMS);
            //theApp.keepRotating();
        };
        image.src = ImgRotator.src;   
    },
    keepRotating:function(){
        ImgRotator.angle+=ImgRotator.jump;
        var canvas = document.getElementById(ImgRotator.canvasID);
        var ctx = canvas.getContext("2d");
        ctx.save();
        ctx.clearRect(0,0,canvas.width,canvas.height);
        ctx.translate(canvas.width/2,canvas.height/2);
        ctx.rotate(ImgRotator.angle*Math.PI/180); 
        ctx.drawImage(ImgRotator.image, -ImgRotator.image.width/2,-ImgRotator.image.height/2);
        ctx.restore();
    }
}

usage

ImgRotator.start_action("canva",

In javascript there are trues and truthys. When something is true it is obviously true or false. When something is truthy it may or may not be a boolean, but the "cast" value of is a boolean.

Examples.

true == true; // (true) true
1 == true; // (true) truthy
"hello" == true;  // (true) truthy
[1, 2, 3] == true; // (true) truthy
[] == false; // (true) truthy
false == false; // (true) true
0 == false; // (true) truthy
"" == false; // (true) truthy
undefined == false; // (true) truthy
null == false; // (true) truthy

This can make things simpler if you want to check if a string is set or an array has any values.

var users = [];

if(users) {
  // this array is populated. do something with the array
}

var name = "";

if(!name) {
  // you forgot to enter your name!
}

And as stated. expect(something).toBe(true) and expect(something).toBeTrue() is the same. But expect(something).toBeTruthy() is not the same as either of those.

I found this post and I have just posted something on my blog that might help.

See Setting up a Msysgit Server with copSSH on Windows. It's long, but I have successfully got this working on Windows 7 Ultimate x64.

I've solved this error downloading the executable file for python 3.7. I've had downloaded the embeddeable version and got that error. Now it works! :D

I do not like transformations to have any more info than needed. So instead of restating the keys, I simply state the condition and intention. It is much easier to see the intention when done like this, at least IMO. Also, I try and put all the xdt attributes first to indicate to the reader, these are transformations and not new things being defined.

<appSettings>
  <add xdt:Locator="Condition(@key='developmentModeUserId')" xdt:Transform="Remove" />
  <add xdt:Locator="Condition(@key='developmentMode')" xdt:Transform="SetAttributes"
       value="false"/>
</appSettings>

In the above it is much easier to see that the first one is removing the element. The 2nd one is setting attributes. It will set/replace any attributes you define here. In this case it will simply set value to false.

Further to RolandTumble's answer to Cody Gray's answer, both fine answers, here is another very simple and flexible way, when you know all of the array contents at coding time - e.g. you just want to build an array that contains 1, 10, 20 and 50. This also uses variant declaration, but doesn't use ReDim. Like in Roland's answer, the enumerated count of the number of array elements need not be specifically known, but is obtainable by using uBound.

sub Demo_array()
    Dim MyArray as Variant, MyArray2 as Variant, i as Long

    MyArray = Array(1, 10, 20, 50)  'The key - the powerful Array() statement
    MyArray2 = Array("Apple", "Pear", "Orange") 'strings work too

    For i = 0 to UBound(MyArray)
        Debug.Print i, MyArray(i)
    Next i
    For i = 0 to UBound(MyArray2)
        Debug.Print i, MyArray2(i)
    Next i
End Sub

I love this more than any of the other ways to create arrays. What's great is that you can add or subtract members of the array right there in the Array statement, and nothing else need be done to code. To add Egg to your 3 element food array, you just type

, "Egg"

in the appropriate place, and you're done. Your food array now has the 4 elements, and nothing had to be modified in the Dim, and ReDim is omitted entirely.

If a 0-based array is not desired - i.e., using MyArray(0) - one solution is just to jam a 0 or "" for that first element.

Note, this might be regarded badly by some coding purists; one fair objection would be that "hard data" should be in Const statements, not code statements in routines. Another beef might be that, if you stick 36 elements into an array, you should set a const to 36, rather than code in ignorance of that. The latter objection is debatable, because it imposes a requirement to maintain the Const with 36 rather than relying on uBound. If you add a 37th element but leave the Const at 36, trouble is possible.

ConcurrentLinkedQueue is lock-free, LinkedBlockingQueue is not. Every time you invoke LinkedBlockingQueue.put() or LinkedBlockingQueue.take(), you need acquire the lock first. In other word, LinkedBlockingQueue has poor concurrency. If you care performance, try ConcurrentLinkedQueue + LockSupport.

Thanks all who attempted to help.
For me this script was helpful. It process only flat JSON and don't take care of types, but automate some routine

  String str =

You can pass a numpy array or matrix as an argument when initializing a sparse matrix. For a CSR matrix, for example, you can do the following.

>>> import numpy as np
>>> from scipy import sparse
>>> A = np.array([[1,2,0],[0,0,3],[1,0,4]])
>>> B = np.matrix([[1,2,0],[0,0,3],[1,0,4]])

>>> A
array([[1, 2, 0],
       [0, 0, 3],
       [1, 0, 4]])

>>> sA = sparse.csr_matrix(A)   # Here's the initialization of the sparse matrix.
>>> sB = sparse.csr_matrix(B)

>>> sA
<3x3 sparse matrix of type '<type 'numpy.int32'>'
        with 5 stored elements in Compressed Sparse Row format>

>>> print sA
  (0, 0)        1
  (0, 1)        2
  (1, 2)        3
  (2, 0)        1
  (2, 2)        4
