I like to make use of the css :before and a data-* attribute for the list

HTML:

<ul data-header="heading"> 
<li>list item </li>
<li>list item </li>
<li>list item </li>
</ul>

CSS:

ul:before{
    content:attr(data-header);
    font-size:120%;
    font-weight:bold;
    margin-left:-15px;
}

This will make a list with the header on it that is whatever text is specified as the list's data-header attribute. You can then easily style it to your needs.

Generically, you can use a custom font using @font-face in your CSS. Here's a very basic example:

@font-face {
    font-family: 'YourFontName'; /*a name to be used later*/
    src: url('http://domain.com/fonts/font.ttf'); /*URL to font*/
}

Then, trivially, to use the font on a specific element:

.classname {
    font-family: 'YourFontName';
}

(.classname is your selector).

Note that certain font-formats don't work on all browsers; you can use fontsquirrel.com's generator to avoid too much effort converting.

You can find a nice set of free web-fonts provided by Google Fonts (also has auto-generated CSS @font-face rules, so you don't have to write your own).

while also preventing people from having free access to download the font, if possible

Nope, it isn't possible to style your text with a custom font embedded via CSS, while preventing people from downloading it. You need to use images, Flash, or the HTML5 Canvas, all of which aren't very practical.

I hope that helped!

That worked for me in Swift 5 like a charm, just add it to your viewDidLoad()

This thread discusses how to install the binary on the simulator. I've done it and it works: http://forums.macrumors.com/showthread.php?t=547557

From the thread:

Look inside your ~/Library/Application Support/iPhone Simulator/User/Applications/ directory and see what happens inside this directory when you install and run apps using XCode, and also when you delete apps using the Simulator.

You can run the Simulator by itself (without starting XCode).

If you start the Simulator, delete an app, quit the Simulator, put back copies of the files that were deleted from the support directory, and restart the Simulator, the app will reappear in the Simulator. Email those files with instructions about how to copy them into the appropriate support directory.

It is better to use API Key in header, not in URL.

URLs are saved in browser's history if it is tried from browser. It is very rare scenario. But problem comes when the backend server logs all URLs. It might expose the API key.

In two ways, you can use API Key in header

Basic Authorization:

Example from stripe:

curl https://api.stripe.com/v1/charges -u sk_test_BQokikJOvBiI2HlWgH4olfQ2:

curl uses the -u flag to pass basic auth credentials (adding a colon after your API key will prevent it from asking you for a password).

Custom Header

curl -H "X-API-KEY: 6fa741de1bdd1d91830ba" https://api.mydomain.com/v1/users

The best sorting technique of all generally depends upon the size of an array. Merge sort can be the best of all as it manages better space and time complexity according to the Big-O algorithm (This suits better for a large array).

You can try this.....

DECLARE @value Varchar(100)=NULL
IF(@value = '' OR @value IS NULL)
  BEGIN
    select 1
  END
ELSE
  BEGIN
    select 0
  END

After digging a lot of stuff, finally, I came up with a good solution that doesn't hang the CI :) Suit it to your needs!

public static Task WaitUntil<T>(T elem, Func<T, bool> predicate, int seconds = 10)
{
    var tcs = new TaskCompletionSource<int>();
    using(var cancellationTokenSource = new CancellationTokenSource(TimeSpan.FromSeconds(seconds)))
    {
        cancellationTokenSource.Token.Register(() =>
        {
            tcs.SetException(
                new TimeoutException($"Waiting predicate {predicate} for {elem.GetType()} timed out!"));
            tcs.TrySetCanceled();
        });

        while(!cancellationTokenSource.IsCancellationRequested)
        {
            try
            {
                if (!predicate(elem))
                {
                    continue;
                }
            }
            catch(Exception e)
            {
                tcs.TrySetException(e);
            }

            tcs.SetResult(0);
            break;
        }

        return tcs.Task;
    }
}

You can try something like this:

StringBuilder sb = new StringBuilder();
if (condition) { sb.append("elementName").append(","); }
if (anotherCondition) { sb.append("anotherElementName").append(","); }
String parameterString = sb.toString();

I would avoid to do a query for each entry.

if(is_array($EMailArr)){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";

    $valuesArr = array();
    foreach($EMailArr as $row){

        $R_ID = (int) $row['R_ID'];
        $email = mysql_real_escape_string( $row['email'] );
        $name = mysql_real_escape_string( $row['name'] );

        $valuesArr[] = "('$R_ID', '$email', '$name')";
    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}

How unique does it need to be?

If it's only unique within a process, then you can use an AtomicInteger and call incrementAndGet() each time you need a new value.

When you see dtype('O') inside dataframe this means Pandas string.

What is dtype?

Something that belongs to pandas or numpy, or both, or something else? If we examine pandas code:

df = pd.DataFrame({'float': [1.0],
                    'int': [1],
                    'datetime': [pd.Timestamp('20180310')],
                    'string': ['foo']})
print(df)
print(df['float'].dtype,df['int'].dtype,df['datetime'].dtype,df['string'].dtype)
df['string'].dtype

It will output like this:

   float  int   datetime string    
0    1.0    1 2018-03-10    foo
---
float64 int64 datetime64[ns] object
---
dtype('O')

You can interpret the last as Pandas dtype('O') or Pandas object which is Python type string, and this corresponds to Numpy string_, or unicode_ types.

Pandas dtype    Python type     NumPy type          Usage
object          str             string_, unicode_   Text

Like Don Quixote is on ass, Pandas is on Numpy and Numpy understand the underlying architecture of your system and uses the class numpy.dtype for that.

Data type object is an instance of numpy.dtype class that understand the data type more precise including:

• Type of the data (integer, float, Python object, etc.)
• Size of the data (how many bytes is in e.g. the integer)
• Byte order of the data (little-endian or big-endian)
• If the data type is structured, an aggregate of other data types, (e.g., describing an array item consisting of an integer and a float)
• What are the names of the "fields" of the structure
• What is the data-type of each field
• Which part of the memory block each field takes
• If the data type is a sub-array, what is its shape and data type

In the context of this question dtype belongs to both pands and numpy and in particular dtype('O') means we expect the string.

Here is some code for testing with explanation: If we have the dataset as dictionary

import pandas as pd
import numpy as np
from pandas import Timestamp

data={'id': {0: 1, 1: 2, 2: 3, 3: 4, 4: 5}, 'date': {0: Timestamp('2018-12-12 00:00:00'), 1: Timestamp('2018-12-12 00:00:00'), 2: Timestamp('2018-12-12 00:00:00'), 3: Timestamp('2018-12-12 00:00:00'), 4: Timestamp('2018-12-12 00:00:00')}, 'role': {0: 'Support', 1: 'Marketing', 2: 'Business Development', 3: 'Sales', 4: 'Engineering'}, 'num': {0: 123, 1: 234, 2: 345, 3: 456, 4: 567}, 'fnum': {0: 3.14, 1: 2.14, 2: -0.14, 3: 41.3, 4: 3.14}}
df = pd.DataFrame.from_dict(data) #now we have a dataframe

print(df)
print(df.dtypes)

The last lines will examine the dataframe and note the output:

   id       date                  role  num   fnum
0   1 2018-12-12               Support  123   3.14
1   2 2018-12-12             Marketing  234   2.14
2   3 2018-12-12  Business Development  345  -0.14
3   4 2018-12-12                 Sales  456  41.30
4   5 2018-12-12           Engineering  567   3.14
id               int64
date    datetime64[ns]
role            object
num              int64
fnum           float64
dtype: object

All kind of different dtypes

df.iloc[1,:] = np.nan
df.iloc[2,:] = None

But if we try to set np.nan or None this will not affect the original column dtype. The output will be like this:

print(df)
print(df.dtypes)

    id       date         role    num   fnum
0  1.0 2018-12-12      Support  123.0   3.14
1  NaN        NaT          NaN    NaN    NaN
2  NaN        NaT         None    NaN    NaN
3  4.0 2018-12-12        Sales  456.0  41.30
4  5.0 2018-12-12  Engineering  567.0   3.14
id             float64
date    datetime64[ns]
role            object
num            float64
fnum           float64
dtype: object

So np.nan or None will not change the columns dtype, unless we set the all column rows to np.nan or None. In that case column will become float64 or object respectively.

You may try also setting single rows:

df.iloc[3,:] = 0 # will convert datetime to object only
df.iloc[4,:] = '' # will convert all columns to object

And to note here, if we set string inside a non string column it will become string or object dtype.

I am trying to set a div to a certain percentage height in CSS

Percentage of what?

To set a percentage height, its parent element(*) must have an explicit height. This is fairly self-evident, in that if you leave height as auto, the block will take the height of its content... but if the content itself has a height expressed in terms of percentage of the parent you've made yourself a little Catch 22. The browser gives up and just uses the content height.

So the parent of the div must have an explicit height property. Whilst that height can also be a percentage if you want, that just moves the problem up to the next level.

If you want to make the div height a percentage of the viewport height, every ancestor of the div, including <html> and <body>, have to have height: 100%, so there is a chain of explicit percentage heights down to the div.

(*: or, if the div is positioned, the ‘containing block’, which is the nearest ancestor to also be positioned.)

Alternatively, all modern browsers and IE>=9 support new CSS units relative to viewport height (vh) and viewport width (vw):

div {
    height:100vh; 
}

See here for more info.

This problem may occur if you have two devices connected to the computer at the same time. Adb does not support reaching both devices via command/console. So, if you debug your app after connecting and disconnecting the second device you will most probably have this problem. One solution might be restarting adb and/or eclipse if necessary. It can be quite annoying sometimes and I am afraid there is no other solution to that.

The specific numbers in the question are from CCIR 601 (see the Wikipedia link below).

If you convert RGB -> grayscale with slightly different numbers / different methods, you won't see much difference at all on a normal computer screen under normal lighting conditions -- try it.

Here are some more links on color in general:

Should you run into "linear" vs "nonlinear" RGB, here's part of an old note to myself on this. Repeat, in practice you won't see much difference.

RGB -> ^gamma -> Y -> L*

In color science, the common RGB values, as in html rgb( 10%, 20%, 30% ), are called "nonlinear" or Gamma corrected. "Linear" values are defined as

Rlin = R^gamma,  Glin = G^gamma,  Blin = B^gamma

where gamma is 2.2 for many PCs. The usual R G B are sometimes written as R' G' B' (R' = Rlin ^ (1/gamma)) (purists tongue-click) but here I'll drop the '.

Brightness on a CRT display is proportional to RGBlin = RGB ^ gamma, so 50% gray on a CRT is quite dark: .5 ^ 2.2 = 22% of maximum brightness. (LCD displays are more complex; furthermore, some graphics cards compensate for gamma.)

To get the measure of lightness called L* from RGB, first divide R G B by 255, and compute

Y = .2126 * R^gamma + .7152 * G^gamma + .0722 * B^gamma

This is Y in XYZ color space; it is a measure of color "luminance". (The real formulas are not exactly x^gamma, but close; stick with x^gamma for a first pass.)

Finally,

L* = 116 * Y ^ 1/3 - 16

"... aspires to perceptual uniformity [and] closely matches human perception of lightness." -- Wikipedia Lab color space

I had the problem not able to load jar file in libs folder in Android Studio. If you have added JAR file in libs folder, then just open build.gradle file and save it without editing anything else. If you have added this line

compile fileTree(dir: 'libs', include: ['*.jar'])

save it and clean the project .. In next build time Android Studio will load the JAR file.

Hope this helps.

From jQuery:

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

Code examples

Initialize a datepicker with the defaultDate option specified.

$(".selector").datepicker({ defaultDate: +7 });

Get or set the defaultDate option, after init.

//getter
var defaultDate = $(".selector").datepicker("option", "defaultDate");
//setter
$(".selector").datepicker("option", "defaultDate", +7);

After the datepicker is intialized you should also be able to set the date with:

$(/*selector*/).datepicker("setDate" , date)

The explanation from Scott Meyers in Effective C++ might help understand when to use them:

Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.

You may want to use FlushInputBuffer to discard any characters mistakenly typed into the console, especially for long running operations, before using ReadKey:

Write-Host -NoNewLine 'Press any key to continue...'
$Host.UI.RawUI.FlushInputBuffer()
$Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown') | Out-Null

You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).

For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.

Function ExtractSDI(ByVal text As String) As String

Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)

If allMatches.count <> 0 Then
    result = allMatches.Item(0).submatches.Item(0)
End If

ExtractSDI = result

End Function

If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:

Ex) =RegexExtract(A1, "(sdi \d+)", ", ")

Here is:

Function RegexExtract(ByVal text As String, _
                      ByVal extract_what As String, _
                      Optional seperator As String = "") As String

Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)

For i = 0 To allMatches.count - 1
    For j = 0 To allMatches.Item(i).submatches.count - 1
        result = result & seperator & allMatches.Item(i).submatches.Item(j)
    Next
Next

If Len(result) <> 0 Then
    result = Right(result, Len(result) - Len(seperator))
End If

RegexExtract = result

End Function

*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.

This is all that is needed to remove the status bar.

Sometimes using row.getLastCellNum() gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.

private int getLastFilledCellPosition(Row row) {
        int columnIndex = -1;

        for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
            Cell cell = row.getCell(i);

            if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
                continue;
            } else {
                columnIndex = cell.getColumnIndex();
                break;
            }
        }

        return columnIndex;
    }

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);

If you use constants then you have no choice:

const numbers = [1, 2, 3]

You can not reasign:

numbers = []

You can only truncate:

numbers.length = 0

This is how I would handle it. This method will work for the Windows OS case and the Linux/Unix OS case (which means it also works for Mac OS X).

public final static void clearConsole()
{
    try
    {
        final String os = System.getProperty("os.name");

        if (os.contains("Windows"))
        {
            Runtime.getRuntime().exec("cls");
        }
        else
        {
            Runtime.getRuntime().exec("clear");
        }
    }
    catch (final Exception e)
    {
        //  Handle any exceptions.
    }
}

Note that this method generally will not clear the console if you are running inside an IDE.

Add these helper classes to the stylesheet.less (you can use http://less2css.org/ to compile them to CSS )

.row.gutter-0 {
    margin-left: 0;
    margin-right: 0;
    [class*="col-"] {
        padding-left: 0;
        padding-right: 0;
    }
}

.row.gutter-10 {
    margin-left: -5px;
    margin-right: -5px;
    [class*="col-"] {
        padding-left: 5px;
        padding-right: 5px;
    }
}

.row.gutter-20 {
    margin-left: -10px;
    margin-right: -10px;
    [class*="col-"] {
        padding-left: 10px;
        padding-right: 10px;
    }
}

And here’s how you can use it in your HTML:

<div class="row gutter-0">
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
</div>

<div class="row gutter-10">
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
</div>

<div class="row gutter-20">
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
    <div class="col-sm-3 col-md-3 col-lg-3">

    </div>
</div>

Run this command:

npm install --save node-sass

This does the same as above. Similarly to the answer above.

File.ReadLines() returns an object of type System.Collections.Generic.IEnumerable<String>
File.ReadAllLines() returns an array of strings.

If you want to use an array of strings you need to call the correct function.

You could use Jim solution, just use ReadAllLines() or you could change your return type.

This would also work:

System.Collections.Generic.IEnumerable<String> lines = File.ReadLines("c:\\file.txt");

You can use any generic collection which implements IEnumerable. IList for an example.

As a quick and very scoped solution:

Task.Result

Both Task.Result and Task.Wait won't allow to improving scalability when used with I/O, as they will cause the calling thread to stay blocked waiting for the I/O to end.

When you call .Result on an incomplete Task, the thread executing the method has to sit and wait for the task to complete, which blocks the thread from doing any other useful work in the meantime. This negates the benefit of the asynchronous nature of the task.

notasync

app.use() is intended for binding middleware to your application. The path is a "mount" or "prefix" path and limits the middleware to only apply to any paths requested that begin with it. It can even be used to embed another application:

// subapp.js
var express = require('express');
var app = modules.exports = express();
// ...

// server.js
var express = require('express');
var app = express();

app.use('/subapp', require('./subapp'));

// ...

By specifying / as a "mount" path, app.use() will respond to any path that starts with /, which are all of them and regardless of HTTP verb used:

• GET /
• PUT /foo
• POST /foo/bar
• etc.

app.get(), on the other hand, is part of Express' application routing and is intended for matching and handling a specific route when requested with the GET HTTP verb:

• GET /

And, the equivalent routing for your example of app.use() would actually be:

app.all(/^\/.*/, function (req, res) {
    res.send('Hello');
});

(Update: Attempting to better demonstrate the differences.)

The routing methods, including app.get(), are convenience methods that help you align responses to requests more precisely. They also add in support for features like parameters and next('route').

Within each app.get() is a call to app.use(), so you can certainly do all of this with app.use() directly. But, doing so will often require (probably unnecessarily) reimplementing various amounts of boilerplate code.

Examples:

• For simple, static routes:

  app.get('/', function (req, res) {
    // ...
  });
  

  vs.

  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    // ...
  });
  

• With multiple handlers for the same route:

  app.get('/', authorize('ADMIN'), function (req, res) {
    // ...
  });
  

  vs.

  const authorizeAdmin = authorize('ADMIN');
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    authorizeAdmin(req, res, function (err) {
      if (err) return next(err);
  
      // ...
    });
  });
  

• With parameters:

  app.get('/item/:id', function (req, res) {
    let id = req.params.id;
    // ...
  });
  

  vs.

  const pathToRegExp = require('path-to-regexp');
  
  function prepareParams(matches, pathKeys, previousParams) {
    var params = previousParams || {};
  
    // TODO: support repeating keys...
    matches.slice(1).forEach(function (segment, index) {
      let { name } = pathKeys[index];
      params[name] = segment;
    });
  
    return params;
  }
  
  const itemIdKeys = [];
  const itemIdPattern = pathToRegExp('/item/:id', itemIdKeys);
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET') return next();
  
    var urlMatch = itemIdPattern.exec(req.url);
    if (!urlMatch) return next();
  
    if (itemIdKeys && itemIdKeys.length)
      req.params = prepareParams(urlMatch, itemIdKeys, req.params);
  
    let id = req.params.id;
    // ...
  });

JDS's answer worked best. C# example loading image:

• Include the image as Resource (Project tree->Resources, right click to add the desirable file ImageName.png)
• Embedded Resource (Project tree->Resources->ImageName.png, right click select properties)
• .png file format (.bmp .jpg should also be OK)

pictureBox1.Image = ProjectName.Properties.Resources.ImageName;

Note the followings:

• The resource image file is "ImageName.png", file extension should be omitted.
• ProjectName may perhaps be more adequately understood as "Assembly name", which is to be the respective text entry on the Project->Properties page.

The example code line is run successfully using VisualStudio 2015 Community.

You can use BeautifulSoup:

from bs4 import BeautifulSoup

x="""<foo>
   <bar>
      <type foobar="1"/>
      <type foobar="2"/>
   </bar>
</foo>"""

y=BeautifulSoup(x)
>>> y.foo.bar.type["foobar"]
u'1'

>>> y.foo.bar.findAll("type")
[<type foobar="1"></type>, <type foobar="2"></type>]

>>> y.foo.bar.findAll("type")[0]["foobar"]
u'1'
>>> y.foo.bar.findAll("type")[1]["foobar"]
u'2'

You can use this

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) 
    {
        // for iOS 8
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [application registerForRemoteNotifications];
    }
    else
    {
        // for iOS < 8
        [application registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
    }

    // RESET THE BADGE COUNT 
    application.applicationIconBadgeNumber = 0;

You can use strtotime:

$date = strtotime('2010-01-01 -1 year');

The strtotime function returns a unix timestamp, to get a formatted string you can use date:

echo date('Y-m-d', $date); // echoes '2009-01-01'

Wrote my own test. tested the code on stackoverflow, works fine tells me that chrome/FF can do 6

var change = 0;
var simultanius = 0;
var que = 20; // number of tests

Array(que).join(0).split(0).forEach(function(a,i){
    var xhr = new XMLHttpRequest;
    xhr.open("GET", "/?"+i); // cacheBust
    xhr.onreadystatechange = function() {
        if(xhr.readyState == 2){
            change++;
            simultanius = Math.max(simultanius, change);
        }
        if(xhr.readyState == 4){
            change--;
            que--;
            if(!que){
                console.log(simultanius);
            }
        }
    };
    xhr.send();
});

it works for most websites that can trigger readystate change event at different times. (aka: flushing)

I notice on my node.js server that i had to output at least 1025 bytes to trigger the event/flush. otherwise the events would just trigger all three state at once when the request is complete so here is my backend:

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

app.get("/", function(req,res) {
    res.write(Array(1025).join("a"));
    setTimeout(function() {
        res.end("a");
    },500);
});

app.listen(80);

Update

I notice that You can now have up to 2x request if you are using both xhr and fetch api at the same time

var change = 0;_x000D_
var simultanius = 0;_x000D_
var que = 30; // number of tests_x000D_

Strings are sorted lexicographically. The behavior you're seeing is correct.

Define your own comparator to sort the strings however you prefer.

It would also work the way you're expecting (5 as the first element) if you changed your collections to Integer instead of using String.

Please follow these Steps:

For Eclipse:

• Go to your Project's Properties
  
• Navigate to the Java Build Path
• Then go to the Libraries tab. There click the Add External JARs Button on the Right pane.
  
• Select the android-support-v4.jar file, usually the path for the Jar file is :
  YOUR_DRIVE\android-sdks\extras\android\support\v4\android-support-v4.jar
  
• After adding android-support-v4.jar Library, navigate to the Order and Export tab and put check mark on the android-support-v4 Library file.
  
• After doing the above, Clean the Project and Build it.
  
• Problem Solved.

For Android Studio:

Short Version:

• Add the following line to your build.gradle file:
  implementation 'com.android.support:support-v4:YOUR_TARGET_VERSION'

Long Version:

• Go to File -> Project Structure

• Go to "Dependencies" Tab -> Click on the Plus sign -> Go to "Library dependency"

• Select the support library "support-v4 (com.android.support:support-v4:YOUR_TARGET_VERSION)"

• Navigate to your "build.gradle" inside your App Directory and double check if your desired Android Support Library has been added to your dependencies.

• Rebuild your project and now everything should work.

The 'Z' is what adds the timezone info. As for output UTC, that seems to be the subject of some confusion -- people seem to gravitate toward moment.js.

Borrowing from this answer, you could do something like this without moment.js:

controller

var app1 = angular.module('app1',[]);

app1.controller('ctrl',['$scope',function($scope){

  var toUTCDate = function(date){
    var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
    return _utc;
  };

  var millisToUTCDate = function(millis){
    return toUTCDate(new Date(millis));
  };

    $scope.toUTCDate = toUTCDate;
    $scope.millisToUTCDate = millisToUTCDate;

  }]);

template

<html ng-app="app1">

  <head>
    <script data-require="angular.js@*" data-semver="1.2.12" src="http://code.angularjs.org/1.2.12/angular.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <div ng-controller="ctrl">
      <div>
      utc {{millisToUTCDate(1400167800) | date:'dd-M-yyyy H:mm'}}
      </div>
      <div>
      local {{1400167800 | date:'dd-M-yyyy H:mm'}}
      </div>
    </div>
  </body>

</html>

here's plunker to play with it

Also note that with this method, if you use the 'Z' from Angular's date filter, it seems it will still print your local timezone offset.

In ASP.NET Web API 2, you can wrap any ResponseMessage in a ResponseMessageResult:

public IHttpActionResult Get()
{
   HttpResponseMessage responseMessage = ...
   return new ResponseMessageResult(responseMessage);
}

In some cases this may be the simplest way to get the desired result, although generally it might be preferable to use the various results in System.Web.Http.Results.

    func addExternalBorder(borderWidth: CGFloat = 2.0, borderColor: UIColor = UIColor.white) -> CALayer {
        let externalBorder = CALayer()
        externalBorder.frame = CGRect(x: -borderWidth, y: -borderWidth, width: frame.size.width + 2 * borderWidth, height: frame.size.height + 2 * borderWidth)
        externalBorder.borderColor = borderColor.cgColor
        externalBorder.borderWidth = borderWidth
        externalBorder.name = Constants.ExternalBorderName

        layer.insertSublayer(externalBorder, at: 0)
        layer.masksToBounds = false

        return externalBorder
    }

    func removeExternalBorders() {
        layer.sublayers?.filter() { $0.name == Constants.externalBorderName }.forEach() {
            $0.removeFromSuperlayer()
        }
    }

    func removeExternalBorder(externalBorder: CALayer) {

If you run the command:

sc queryex <service name>

where is the the name of the service, not the display name (spooler, not Print Spooler), at the cmd prompt it will return the PID of the process the service is running as. Take that PID and run

taskkill /F /PID <Service PID>

to force the PID to stop. Sometimes if the process hangs while stopping the GUI won't let you do anything with the service.

First difference - Fail Fast

I agree with @zzzzBov's answer, but the "fail fast" advantage of Promise.all is not the only difference. Some users in the comments have asked why using Promise.all is worth it when it's only faster in the negative scenario (when some task fails). And I ask, why not? If I have two independent async parallel tasks and the first one takes a very long time to resolve but the second is rejected in a very short time, why leave the user to wait for the longer call to finish to receive an error message? In real-life applications we must consider the negative scenario. But OK - in this first difference you can decide which alternative to use: Promise.all vs. multiple await.

Second difference - Error Handling

But when considering error handling, YOU MUST use Promise.all. It is not possible to correctly handle errors of async parallel tasks triggered with multiple awaits. In the negative scenario you will always end with UnhandledPromiseRejectionWarning and PromiseRejectionHandledWarning, regardless of where you use try/ catch. That is why Promise.all was designed. Of course someone could say that we can suppress those errors using process.on('unhandledRejection', err => {}) and process.on('rejectionHandled', err => {}) but this is not good practice. I've found many examples on the internet that do not consider error handling for two or more independent async parallel tasks at all, or consider it but in the wrong way - just using try/ catch and hoping it will catch errors. It's almost impossible to find good practice in this.

Summary

TL;DR: Never use multiple await for two or more independent async parallel tasks, because you will not be able to handle errors correctly. Always use Promise.all() for this use case.

Async/ await is not a replacement for Promises, it's just a pretty way to use promises. Async code is written in "sync style" and we can avoid multiple thens in promises.

Some people say that when using Promise.all() we can't handle task errors separately, and that we can only handle the error from the first rejected promise (separate handling can be useful e.g. for logging). This is not a problem - see "Addition" heading at the bottom of this answer.

Examples

Consider this async task...

const task = function(taskNum, seconds, negativeScenario) {
  return new Promise((resolve, reject) => {
    setTimeout(_ => {
      if (negativeScenario)
        reject(new Error('Task ' + taskNum + ' failed!'));
      else
        resolve('Task ' + taskNum + ' succeed!');
    }, seconds * 1000)
  });
};

When you run tasks in the positive scenario there is no difference between Promise.all and multiple awaits. Both examples end with Task 1 succeed! Task 2 succeed! after 5 seconds.

// Promise.all alternative
const run = async function() {
  // tasks run immediate in parallel and wait for both results
  let [r1, r2] = await Promise.all([
    task(1, 5, false),
    task(2, 5, false)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

// multiple await alternative
const run = async function() {
  // tasks run immediate in parallel
  let t1 = task(1, 5, false);
  let t2 = task(2, 5, false);
  // wait for both results
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

However, when the first task takes 10 seconds and succeeds, and the second task takes 5 seconds but fails, there are differences in the errors issued.

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
      task(1, 10, false),
      task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

We should already notice here that we are doing something wrong when using multiple awaits in parallel. Let's try handling the errors:

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, false),
    task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: Caught error Error: Task 2 failed!

As you can see, to successfully handle errors, we need to add just one catch to the run function and add code with catch logic into the callback. We do not need to handle errors inside the run function because async functions do this automatically - promise rejection of the task function causes rejection of the run function.

To avoid a callback we can use "sync style" (async/ await + try/ catch)
try { await run(); } catch(err) { }
but in this example it's not possible, because we can't use await in the main thread - it can only be used in async functions (because nobody wants to block main thread). To test if handling works in "sync style" we can call the run function from another async function or use an IIFE (Immediately Invoked Function Expression: MDN):

(async function() { 
  try { 
    await run(); 
  } catch(err) { 
    console.log('Caught error', err); 
  }
})();

This is the only correct way to run two or more async parallel tasks and handle errors. You should avoid the examples below.

Bad Examples

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};

We can try to handle errors in the code above in several ways...

try { run(); } catch(err) { console.log('Caught error', err); };
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled 

... nothing got caught because it handles sync code but run is async.

run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... huh? We see firstly that the error for task 2 was not handled and later that it was caught. Misleading and still full of errors in console, it's still unusable this way.

(async function() { try { await run(); } catch(err) { console.log('Caught error', err); }; })();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... the same as above. User @Qwerty in his deleted answer asked about this strange behavior where an error seems to be caught but are also unhandled. We catch error the because run() is rejected on the line with the await keyword and can be caught using try/ catch when calling run(). We also get an unhandled error because we are calling an async task function synchronously (without the await keyword), and this task runs and fails outside the run() function.
It is similar to when we are not able to handle errors by try/ catch when calling some sync function which calls setTimeout:

function test() {
  setTimeout(function() { 
    console.log(causesError); 
    }, 0);
}; 
try { 
  test(); 
} catch(e) { 
  /* this will never catch error */ 
}`.

Another poor example:

const run = async function() {
  try {
    let t1 = task(1, 10, false);
    let t2 = task(2, 5, true);
    let r1 = await t1;
    let r2 = await t2;
  }
  catch (err) {
    return new Error(err);
  }
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... "only" two errors (3rd one is missing) but nothing is caught.

Addition (handling separate task errors and also first-fail error)

const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, true).catch(err => { console.log('Task 1 failed!'); throw err; }),
    task(2, 5, true).catch(err => { console.log('Task 2 failed!'); throw err; })
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Run failed (does not matter which task)!'); });
// at 5th sec: Task 2 failed!
// at 5th sec: Run failed (does not matter which task)!
// at 10th sec: Task 1 failed!

... note that in this example I rejected both tasks to better demonstrate what happens (throw err is used to fire final error).

For MacPorts, just use the load/unload command and the port name of the running server:

sudo port load postgresql96-server
- or -
sudo port unload postgresql96-server

so you don't have to remember where the /Library/LaunchDaemons/org.macports.postgresql96.plist file is located.

Are you using JTextArea's append(String) method to add additional text?

JTextArea txtArea = new JTextArea("Hello, World\n", 20, 20);
txtArea.append("Goodbye Cruel World\n");

Use "\\" to escape the \ character.

It works fine with Salesforce REST API query datetime formats

DateTime now = DateTime.UtcNow;
string startDate = now.AddDays(-5).ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");   
string endDate = now.ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");  
//REST service Query 
string salesforceUrl= https://csxx.salesforce.com//services/data/v33.0/sobjects/Account/updated/?start=" + startDate + "&end=" + endDate;

// https://csxx.salesforce.com/services/data/v33.0/sobjects/Account/updated/?start=2015-03-10T15:15:57Z&end=2015-03-15T15:15:57Z

It returns the results from Salesforce without any issues.

You have to use the escaped unicode :

Like

Below is the code that worked for me. We use jpa 1.0, Apache openjpa implementation.

import java.sql.Connection;
import org.apache.openjpa.persistence.OpenJPAEntityManager;
import org.apache.openjpa.persistence.OpenJPAPersistence;

public final class MsSqlDaoFactory {


       public static final Connection getConnection(final EntityManager entityManager) {
              OpenJPAEntityManager openJPAEntityManager = OpenJPAPersistence.cast(entityManager);
              Connection connection = (Connection) openJPAEntityManager.getConnection();
              return connection;

        }

}

1. Create SDK folder at \Android\Sdk
2. Close any project which is already open in Android studio

Android Studio setup wizard will appear and perform the needed installation.

The problem was that I ran the commands within the folder /project/src/app. Navigating back to the project folder so to /project and running ng serve from there solved my problem.

You can keep track the position of the current selected element:

    OnItemClickListener listViewOnItemClick = new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> adapter, View arg1, int position, long id) {
                mSelectedItem = position;
                mAdapter.notifyDataSetChanged();
        }
    };

And override the getView method of your adapter:

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final View view = View.inflate(context, R.layout.item_list, null);

        if (position == mSelectedItem) {
            // set your color
        }

        return view;
    }

For me it did the trick.

I had this same problem and it occurred because I had hit the enter key when adding code in a text string.

Because it was a long string of text I wanted to see it all without having to scroll in my text editor, however hitting enter added an invisible character to the string which was illegal. I was using Sublime Text as my editor.

Here is a directive that you can use in any component:

import { NgZone, Directive, ElementRef, AfterContentInit, Renderer2 } from '@angular/core';

@Directive({
    selector: '[appFocus]'
})
export class FocusDirective implements AfterContentInit {
    constructor(private el: ElementRef, private zone: NgZone, private renderer: Renderer2) {}

    ngAfterContentInit() {
        this.zone.runOutsideAngular(() => setTimeout(() => {
            this.renderer.selectRootElement(this.el.nativeElement).focus();
        }, 0));
    }
}

Use:

<input type="text" appFocus>

In a node.js server console.log outputs to the terminal window, not to the browser's console window.

How are you running your server? You should see the output directly after you start it.

With Bootstrap... This answer (https://stackoverflow.com/a/23005046/1128742) got me pointed towards this solution:

<ul class="list-unstyled row">
   <li class="col-xs-6">Item 1</li>
   <li class="col-xs-6">Item 2</li>
   <li class="col-xs-6">Item 3</li>
</ul>

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

I found it useful to get a location of the library file with:

gem which *gemname*

var json_data = {"2013-01-21":1,"2013-01-22":7};
var result = [];

for(var i in json_data)
    result.push([i, json_data [i]]);


var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows(result);

The problem with the first answer is that the placeholder will be uppercase too. In case you want ONLY the input to be uppercase, use the following solution.

In order to select only non-empty input element, put required attribute on the element:

<input type="text" id="name-input" placeholder="Enter symbol" required="required" />

Now, in order to select it, use the :valid pseudo-element:

#name-input:valid { text-transform: uppercase; }

This way you will uppercase only entered characters.

If you have a view with multiple constrains, a much easier way without having to create multiple outlets would be:

In interface builder, give each constraint you wish to modify an identifier:

Then in code you can modify multiple constraints like so:

for constraint in self.view.constraints {
    if constraint.identifier == "myConstraint" {
       constraint.constant = 50
    }
}
myView.layoutIfNeeded()

You can give multiple constrains the same identifier thus allowing you to group together constrains and modify all at once.

You can use the function file_get_contents();

if(file_get_contents('https://example.com/example.txt')) {
    //File exists
}

The problem solutions are fine but I found some problems in both:

• As Carter Shanklin said, with this command we will obtain a csv file with the results of the query in the path specified:

  insert overwrite local directory '/home/carter/staging' row format delimited fields terminated by ',' select * from hugetable;
  

  The problem with this solution is that the csv obtained won´t have headers and will create a file that is not a CSV (so we have to rename it).

• As user1922900 said, with the following command we will obtain a CSV files with the results of the query in the specified file and with headers:

  hive -e 'select * from some_table' | sed 's/[\t]/,/g' > /home/yourfile.csv
  

  With this solution we will get a CSV file with the result rows of our query, but with log messages between these rows too. As a solution of this problem I tried this, but without results.

So, to solve all these issues I created a script that execute a list of queries, create a folder (with a timestamp) where it stores the results, rename the files obtained, remove the unnecesay files and it also add the respective headers.

 #!/bin/sh
 QUERIES=("select * from table1" "select * from table2")
 IFS=""
 directoryname=$(echo "ScriptResults$timestamp")
 mkdir $directoryname 
 counter=1 
for query in ${QUERIES[*]}
 do 
     tablename="query"$counter 
     hive -S -e "INSERT OVERWRITE LOCAL DIRECTORY '/data/2/DOMAIN_USERS/SANUK/users/$USER/$tablename' ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' $query ;"
     hive -S -e "set hive.cli.print.header=true; $query limit 1" | head -1 | sed 's/[\t]/,/g' >> /data/2/DOMAIN_USERS/SANUK/users/$USER/$tablename/header.csv
     mv $tablename/000000_0 $tablename/$tablename.csv
     cat $tablename/$tablename.csv >> $tablename/header.csv.
     rm $tablename/$tablename.csv
     mv $tablename/header.csv $tablename/$tablename.csv 
     mv $tablename/$tablename.csv $directoryname
     counter=$((counter+1))
     rm -rf $tablename/ 
 done

Difference between greedy method and dynamic programming are given below :

1. Greedy method never reconsiders its choices whereas Dynamic programming may consider the previous state.

2. Greedy algorithm is less efficient whereas Dynamic programming is more efficient.

3. Greedy algorithm have a local choice of the sub-problems whereas Dynamic programming would solve the all sub-problems and then select one that would lead to an optimal solution.

4. Greedy algorithm take decision in one time whereas Dynamic programming take decision at every stage.

<?php echo substr("abcabcabc", 0, -3); ?>

The updating of the password in the windows credential manager was not the solution for me.

I had to set a different remote url, by:

git remote set-url origin https://gitlab....git

The url in this case was the one that could be found in Gitlab under Clone -> Clone with HTTPS. It was not the one in the command line instructions.

One of the above answer provides the solution:

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

The problem with above solution is that it has to be done on the linux shell. However, if you are providing your code to work on the client machine then this is a bad approach. I also tried executing the above commands using os.system(), but still it doesn't work.

Solution that worked for me is

locale.setlocale(locale.LC_ALL,'en_US.UTF-8')

Try working with this C# snippet I just crafted:

using System;
using System.IO;
using System.Security.AccessControl;
using System.Security.Principal;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string directory = @"C:\downloads";

            DirectoryInfo di = new DirectoryInfo(directory);

            DirectorySecurity ds = di.GetAccessControl();

            foreach (AccessRule rule in ds.GetAccessRules(true, true, typeof(NTAccount)))
            {
                Console.WriteLine("Identity = {0}; Access = {1}", 
                              rule.IdentityReference.Value, rule.AccessControlType);
            }
        }
    }
}

And here's a reference you could also look at. My code might give you an idea as to how you could check for permissions before attempting to write to a directory.

Another possibility would be the use of REGEXP_SUBSTR.

Firebug 2 does now incorporate DOM events debugging / inspection.

Here's the answer

Steps to follow:

1. Open the Visual Basic Editor. In Excel, hit Alt+F11 if on Windows, Fn+Option+F11 if on a Mac.

2. Insert a new module. From the menu: Insert -> Module (Don't skip this!).

3. Create a Public function. Example:

   Public Function findArea(ByVal width as Double, _
                            ByVal height as Double) As Double
       ' Return the area
       findArea = width * height
   End Function
   

4. Then use it in any cell like you would any other function: =findArea(B12,C12).

Not the solution, but you can use debug key for signing release builds to avoid blocking the installation from Google Play Protect. It looks like Play Protect doesn't warn for builds signed with automatically generated debug.keystore.

Note that your debug builds are not unsigned, they are just signed with a debug key.

Of course, you cannot use the build for production distribution (Google Play, Amazon, etc.), but it's still worth for pre-production internal testing which requires a high-frequency feedback loop.

You can add a task to build release with debug.keystore by adding the configuration in build.gradle, something like:

android {
  buildTypes {
    // add after the `release` definition
    releaseDebugKey { initWith release }
  }

  signingConfigs {
    // use debug.keystore for releaseDebugKey builds
    releaseDebugKey { initWith debug }
  }
}

then execute ./gradlew assembleReleaseDebugKey to build a release build with debug key.

I like the idea of redefining existing tags if they're unused due to the fact that the text is cleaner, at the expense of existing tags. The inline styling works but creates a lot of noise when reading the raw text.

Using VSCode I've found that custom single-letter tags, supported by a small <style> section at the top, works well with a minimum of noise, especially for spot colour, e.g.

<style>
r { color: Red }
o { color: Orange }
g { color: Green }
</style>

# TODOs:

- <r>TODO:</r> Important thing to do
- <o>TODO:</o> Less important thing to do
- <g>DONE:</g> Breath deeply and improve karma

My use-case is orgmode-ish in-app note taking during development but I guess it might work elsewhere?

Remove obj and just do this inside your for loop:

arr.push(i);

Also, the i < yearEnd condition will not include the final year, so change it to i <= yearEnd.

Try using "font/opentype".

VanillaJS === JavaScript i.e.VanillaJS is native JavaScript

Why, Vanilla says it all!!!

Computer software, and sometimes also other computing-related systems like computer hardware or algorithms, are called vanilla when not customized from their original form, meaning that they are used without any customization or updates applied to them (Refer this article). So Vanilla often refers to pure or plain.

In the English language Vanilla has a similar meaning, In information technology, vanilla (pronounced vah-NIHL-uh ) is an adjective meaning plain or basic. Or having no special or extra features, ordinary or standard.

So why name it VanillaJS? As the accepted answer says some bosses want to work with a framework (because it's more organized and flexible and do all the things we want??) but simply JavaScript will do the job. Yet you need to add a framework somewhere. Use VanillaJS...

Is it a Joke? YES

Want some fun? Where can you find it, http://vanilla-js.com/ Download and see for yourself!!! It's 0 bytes uncompressed, 25 bytes gzipped :D

Found this pun on internet regarding JS frameworks (Not to condemn the existing JS frameworks though, they'll make life really easy :)),

Another way to drop the index is to use a list comprehension:

df.columns = [col[1] for col in df.columns]

   b  c
0  1  2
1  3  4

This strategy is also useful if you want to combine the names from both levels like in the example below where the bottom level contains two 'y's:

cols = pd.MultiIndex.from_tuples([("A", "x"), ("A", "y"), ("B", "y")])
df = pd.DataFrame([[1,2, 8 ], [3,4, 9]], columns=cols)

   A     B
   x  y  y
0  1  2  8
1  3  4  9

Dropping the top level would leave two columns with the index 'y'. That can be avoided by joining the names with the list comprehension.

df.columns = ['_'.join(col) for col in df.columns]

    A_x A_y B_y
0   1   2   8
1   3   4   9

That's a problem I had after doing a groupby and it took a while to find this other question that solved it. I adapted that solution to the specific case here.

Here's a nice easy way I found:

h <- hist(g, breaks = 10, density = 10,
          col = "lightgray", xlab = "Accuracy", main = "Overall") 
xfit <- seq(min(g), max(g), length = 40) 
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g)) 
yfit <- yfit * diff(h$mids[1:2]) * length(g) 

lines(xfit, yfit, col = "black", lwd = 2)

Here is the sample code.

System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.StreamWriter writer = new System.IO.StreamWriter(ms);
writer.Write("Hello its my sample file");
writer.Flush();
writer.Dispose();
ms.Position = 0;

System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Plain);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(ms, ct);
attach.ContentDisposition.FileName = "myFile.txt";

// I guess you know how to send email with an attachment
// after sending email
ms.Close();

Edit 1

You can specify other file types by System.Net.Mime.MimeTypeNames like System.Net.Mime.MediaTypeNames.Application.Pdf

Based on Mime Type you need to specify correct extension in FileName for instance "myFile.pdf"

1. Generate an SSH key

Linux/Mac

Open terminal to create ssh keys:

cd ~                 #Your home directory
ssh-keygen -t rsa    #Press enter for all values

For Windows

(Only works if the commit program is capable of using certificates/private & public ssh keys)

1. Use Putty Gen to generate a key
2. Export the key as an open SSH key

Here is a walkthrough on putty gen for the above steps

2. Associate the SSH key with the remote repository

This step varies, depending on how your remote is set up.

• If it is a GitHub repository and you have administrative privileges, go to settings and click 'add SSH key'. Copy the contents of your ~/.ssh/id_rsa.pub into the field labeled 'Key'.

• If your repository is administered by somebody else, give the administrator your id_rsa.pub.

• If your remote repository is administered by your, you can use this command for example:

  scp ~/.ssh/id_rsa.pub YOUR_USER@YOUR_IP:~/.ssh/authorized_keys/id_rsa.pub

3. Set your remote URL to a form that supports SSH ¹

If you have done the steps above and are still getting the password prompt, make sure your repo URL is in the form

git+ssh://[email protected]/username/reponame.git

as opposed to

https://github.com/username/reponame.git

To see your repo URL, run:

git remote show origin

You can change the URL with:

git remote set-url origin git+ssh://[email protected]/username/reponame.git

Basically, you want to loop through each direct descendent of the old-parent node, and move it to the new parent. Any children of a direct descendent will get moved with it.

var newParent = document.getElementById('new-parent');
var oldParent = document.getElementById('old-parent');

while (oldParent.childNodes.length > 0) {
    newParent.appendChild(oldParent.childNodes[0]);
}

The example bellow explains how to remove bullets using a css style class. You can use , similar to css class, by identifier (#id), by parent tag, etc. The same way you can use to define a css to remove bullets from the page footer.

I've used this site as a starting point.

<html>
<head>
<style type="text/css">
div.ui-menu li {
    list-style:none;
    background-image:none;
    background-repeat:none;
    background-position:0; 
}
ul
{
    list-style-type:none;
    padding:0px;
    margin:0px;
}
li
{
    background-image:url(sqpurple.gif);
    background-repeat:no-repeat;
    background-position:0px 5px; 
    padding-left:14px;
}
</style>
</head>

<body>

<div class="ui-menu">
<ul>
<li>Coffee</li>
<li>Tea</li>
<li>Coca Cola</li>
</ul>
</div>

<ul>
<li>Coffee</li>
<li>Tea</li>
<li>Coca Cola</li>
</ul>
</body>

</html>

If you wanna maintain the same order in your list, say: your Map looks like:

map.put(1, "msg1")
map.put(2, "msg2")
map.put(3, "msg3")

and you want your list looks like

["msg1", "msg2", "msg3"]   // same order as the map

you will have to iterate through the Map:

// sort your map based on key, otherwise you will get IndexOutofBoundException
Map<String, String> treeMap = new TreeMap<String, String>(map)

List<String> list = new List<String>();
for (treeMap.Entry<Integer, String> entry : treeMap.entrySet()) {
    list.add(entry.getKey(), entry.getValue());
}  

I was just playing around with this, too. One way you can add extra weight is in the ORDER BY area of the code.

For example, if you were matching 3 different columns and wanted to more heavily weight certain columns:

SELECT search.*,
MATCH (name) AGAINST ('black' IN BOOLEAN MODE) AS name_match,
MATCH (keywords) AGAINST ('black' IN BOOLEAN MODE) AS keyword_match,
MATCH (description) AGAINST ('black' IN BOOLEAN MODE) AS description_match
FROM search
WHERE MATCH (name, keywords, description) AGAINST ('black' IN BOOLEAN MODE)
ORDER BY (name_match * 3  + keyword_match * 2  + description_match) DESC LIMIT 0,100;

You can do this all within your controller by using the $window service here. $window is a wrapper around the global browser object window.

To make this work inject $window into you controller as follows

.controller('exampleCtrl', ['$scope', '$window',
    function($scope, $window) {
        $scope.redirectToGoogle = function(){
            $window.open('https://www.google.com', '_blank');
        };
    }
]);

this works well when redirecting to dynamic routes

I have found the solution. While the Visual Studio IDE installed successfully it did not install any build tools and therefore did not install the C++ compiler.

By attempting to manually create a C++ project in the Visual Studio 2015 GUI I was able to prompt it to download the C++ packages. CMake was then able to find the compiler without any difficulty.

As of R 3.3.0, one may use startsWith() as a faster alternative to grepl():

which(startsWith(mydata_2$height_seca1, 1578))

I got this error message when I entered a number (999999) that was out of the range I'd set for the form.

<input type="number" ng-model="clipInMovieModel" id="clipInMovie" min="1" max="10000">

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

You could use shallow clones (git > 1.9):

git clone --depth depth remote-url

If you are designing your Javafx application using SceneBuilder then use -fx-text-fill(if not available as option then write it in style input box) as style and give the color you want,it will change the text color of your Textfield.

I came here for the same problem and solved it in this way.

Firstly, you are using Capacity instead of Count.

Secondly, if you only need to delete one item, then you can happily use a loop. You just need to ensure that you break out of the loop after deleting an item, like so:

int target = 4;

for (int i = 0; i < list.Count; ++i)
{
    if (list[i].UniqueID == target)
    {
        list.RemoveAt(i);
        break;
    }
}

If you want to remove all items from the list that match an ID, it becomes even easier because you can use List<T>.RemoveAll(Predicate<T> match)

int target = 4;

list.RemoveAll(element => element.UniqueID == target);

Adding to the accepted answer, you can used DATABASE_DEFAULT as encoding.

This allows database to make choice for you and your code becomes more portable.

SELECT MyColumn
FROM 
    FirstTable a
        INNER JOIN SecondTable b
            ON a.MyID COLLATE DATABASE_DEFAULT = b.YourID COLLATE DATABASE_DEFAULT

<input type="button" value="Reload Page" onClick="window.location.href=window.location.href">

git status does not always show the difference between master and origin/master even after a fetch.

If you want the combination git fetch origin && git status to work, you need to specify the tracking information between the local branch and origin:

# git branch --set-upstream-to=origin/<branch> <branch>

For the master branch:

git branch --set-upstream-to=origin/master master

You should put your processing into the class constructor or an OnInit hook method.

I am sure you could make a little SOAP client with Axis. Axis installation instructions.

Since most solutions uses jQuery or are not this satisfying as I wished it to be I wrote a snippet for myself for mootools.

function fix_placeholder(container){
    if(container == null) container = document.body;

    if(!('placeholder' in document.createElement('input'))){

        var inputs = container.getElements('input');
        Array.each(inputs, function(input){

            var type = input.get('type');

            if(type == 'text' || type == 'password'){

                var placeholder = input.get('placeholder');
                input.set('value', placeholder);
                input.addClass('__placeholder');

                if(!input.hasEvent('focus', placeholder_focus)){
                    input.addEvent('focus', placeholder_focus);
                }

                if(!input.hasEvent('blur', placeholder_blur)){
                    input.addEvent('blur', placeholder_blur);
                }

            }

        });

    }
}

function placeholder_focus(){

    var input = $(this);    

    if(input.get('class').contains('__placeholder') || input.get('value') == ''){
        input.removeClass('__placeholder');
        input.set('value', '');
    }

}

function placeholder_blur(){

    var input = $(this);    

    if(input.get('value') == ''){
        input.addClass('__placeholder');
        input.set('value', input.get('placeholder'));
    }

}

I confess that it looks a bit more MORE than others but it works fine. __placeholder is a ccs-class to make the color of the placeholder text fancy.

I used the fix_placeholder in window.addEvent('domready', ... and for any additinally added code like popups.

Hope you like it.

Kind regards.

First check if your default_character_set_name is utf8.

SELECT default_character_set_name FROM information_schema.SCHEMATA S WHERE schema_name = "DBNAME";

If the result is not utf8 you must convert your database. At first you must save a dump.

To change the character set encoding to UTF-8 for all of the tables in the specified database, type the following command at the command line. Replace DBNAME with the database name:

mysql --database=DBNAME -B -N -e "SHOW TABLES" | awk '{print "SET foreign_key_checks = 0; ALTER TABLE", $1, "CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci; SET foreign_key_checks = 1; "}' | mysql --database=DBNAME

To change the character set encoding to UTF-8 for the database itself, type the following command at the mysql> prompt. Replace DBNAME with the database name:

ALTER DATABASE DBNAME CHARACTER SET utf8 COLLATE utf8_general_ci;

You can now retry to to write utf8 character into your database. This solution help me when i try to upload 200000 row of csv file into my database.

I faced a similar issue. I checked for the below:

1. if ssh is not installed on your machine, you will have to install it firstly. (You will get a message saying ssh is not recognized as a command).
2. Port 22 is open or not on the server you are trying to ssh.
3. If the control of remote server is in your hands and you have permissions, try to disable firewall on it.
4. Try to ssh again.

If port is not an issue then you would have to check for firewall settings as it is the one that is blocking your connection.

For me too it was a firewall issue between my machine and remote server.I disabled the firewall on the remote server and I was able to make a connection using ssh.

For Ubuntu 17.0 +

Adding to @netcoder answer above, If you are using Ubuntu 17+, installing libcurl header files is half of the solution. The installation path in ubuntu 17.0+ is different than the installation path in older Ubuntu version. After installing libcurl, you will still get the "cURL not found" error. You need to perform one extra step (as suggested by @minhajul in the OP comment section).

Add a symlink in /usr/include of the cURL installation folder (cURL installation path in Ubuntu 17.0.4 is /usr/include/x86_64-linux-gnu/curl).

My server was running Ubuntu 17.0.4, the commands to enable cURL support were

sudo apt-get install libcurl4-gnutls-dev

Then create a link to cURL installation

cd /usr/include
sudo ln -s x86_64-linux-gnu/curl

In order to resolve java.lang.OutOfMemoryError: Java heap space in Maven, try to configure below configuration in pom

Here's how to pick a random sample out of each group:

SELECT GROUPING_COLUMN, 
       MIN (COLUMN_NAME) KEEP (DENSE_RANK FIRST ORDER BY DBMS_RANDOM.VALUE) 
         AS RANDOM_SAMPLE
FROM TABLE_NAME
GROUP BY GROUPING_COLUMN
ORDER BY GROUPING_COLUMN;

I'm not sure how efficient it is, but if you have a lot of categories and sub-categories, this seems to do the job nicely.

Here is a complete solution(returns 0 if number is overflown):

public int reverse(int x) {
    boolean flag = false;

    // Helpful to check if int is within range of "int"
    long num = x;

    // if the number is negative then turn the flag on.
    if(x < 0) {
        flag = true;
        num = 0 - num;
    }

    // used for the result.
    long result = 0;

    // continue dividing till number is greater than 0
    while(num > 0) {
        result = result*10 + num%10;
        num= num/10;
    }

    if(flag) {
        result = 0 - result;
    }

    if(result > Integer.MAX_VALUE || result < Integer.MIN_VALUE) {
        return 0;
    }
    return (int) result;
}

To create and save an object in a single step, use the create() method.

Yes. You can use the title attribute on cell elements, with poor usability, or you can use CSS tooltips (several existing questions, possibly duplicates of this one).

For me the clean way to do that is this one.

Adapter constructor

private class EnvironmentTypeRecyclerViewAdapter extends RecyclerView.Adapter<EnvironmentTypeRecyclerViewAdapter.ViewHolder>
{
     private final EnvironmentTypeRecyclerViewAdapterListener mEnvironmentTypeRecyclerViewAdapterListener;
     private List<Environment> mEnvironmentsData;

     public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
     {
         public ViewHolder(View v)
         {
             super(v);
             v.setOnClickListener(this);

         }

         @Override
         public void onClick(View v)
         {
              Environment environment = mEnvironmentsData.get(getAdapterPosition());
              if (mEnvironmentTypeRecyclerViewAdapterListener != null && environment != null) {
                      mEnvironmentTypeRecyclerViewAdapterListener.onListItemSelected(environment);      
              }
        }

        public EnvironmentTypeRecyclerViewAdapter(List<SmallCellEnvironment> environments, EnvironmentTypeRecyclerViewAdapterListener environmentTypeRecyclerViewAdapterListener)
        {
            mEnvironmentTypeRecyclerViewAdapterListener = environmentTypeRecyclerViewAdapterListener;
            mEnvironmentsData = environments;
        }
}

The Linked Interface

private interface EnvironmentTypeRecyclerViewAdapterListener
{
    void onListItemSelected(Environment environment);
}

Just to add couple cents to this.

The "delete_by_query" mentioned at the top is still available as a plugin in elasticsearch 2.x.

Although in the latest upcoming version 5.x it will be replaced by "delete by query api"

You can use jasper report.

iReport is a very effective tool to develop jasper reports.

It supports almost all the facilities provided by crystal report like formatting, grouping, creation of charts etc.

So this may not be the issue for you, but I was struggling with this error. I discovered what was causing my problem, though I can't really explain as to why.

For me, mysqli_connect was working fine where the connection was made on pages in any various sub-directory. For some reason though, the same code referenced on pages in the root directory was returning this error. The strange thing is that it was working fine on my localhost environment in MAMP in the root directory, however on my shared host it was not.

After struggling to figure out what was giving me "Error 500" white screen from this "PHP Fatal Error," I went through the code and stumbled upon this code in the error handling that was suggested by the PHP Manual (https://www.php.net/manual/en/mysqli.error.php).

if (!mysqli_query($link, "SET a=1")) {
    printf("Error message: %s\n", mysqli_error($link));
}

I randomly decided to remove it and, voila, connection to the database working in root directories. Maybe someone smarter than me can explain this, for anyone struggling with a similar issue.

For Fedora:

# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"

# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:

s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])

In the other hand, using REST API of other servers are very popular in PHP. Suppose you are looking for a way to redirect some HTTP requests into the other server (for example getting an xml file). Here is a PHP package to help you:

https://github.com/romanpitak/PHP-REST-Client

So, getting the xml file:

$client = new Client('http://example.com');
$request = $client->newRequest('/filename.xml');
$response = $request->getResponse();
echo $response->getParsedResponse();

According to this link

Actually, SO_REUSEADDR flag can lead to much greater consequences: SO_REUSADDR permits you to use a port that is stuck in TIME_WAIT, but you still can not use that port to establish a connection to the last place it connected to. What? Suppose I pick local port 1010, and connect to foobar.com port 300, and then close locally, leaving that port in TIME_WAIT. I can reuse local port 1010 right away to connect to anywhere except for foobar.com port 300.

However you can completely avoid TIME_WAIT state by ensuring that the remote end initiates the closure (close event). So the server can avoid problems by letting the client close first. The application protocol must be designed so that the client knows when to close. The server can safely close in response to an EOF from the client, however it will also need to set a timeout when it is expecting an EOF in case the client has left the network ungracefully. In many cases simply waiting a few seconds before the server closes will be adequate.

I also advice you to learn more about networking and network programming. You should now at least how tcp protocol works. The protocol is quite trivial and small and hence, may save you a lot of time in future.

With netstat command you can easily see which programs ( (program_name,pid) tuple) are binded to which ports and what is the socket current state: TIME_WAIT, CLOSING, FIN_WAIT and so on.

A really good explanation of linux network configurations can be found https://serverfault.com/questions/212093/how-to-reduce-number-of-sockets-in-time-wait.

It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;

or

char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);

will print

X
3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';

Class Assertions in org.junit.jupiter.api

Use:

public static void assertArrayEquals(int[] expected,
                                     int[] actual)

Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.

RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);

The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.

It is originally an answer in the comments from @Mark Rajcok, But I want to place it here as a tested and worked as a solution using ChangeDetectorRef , I see a good point here:

Another alternative is to inject ChangeDetectorRef and call cdRef.detectChanges() instead of zone.run(). This could be more efficient, since it will not run change detection over the entire component tree like zone.run() does. – Mark Rajcok

So code must be like:

import {Component, OnInit, ChangeDetectorRef} from 'angular2/core';

export class RecentDetectionComponent implements OnInit {

    recentDetections: Array<RecentDetection>;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        timer.subscribe(() => this.getRecentDetections());
    }
} 

Edit: Using .detectChanges() inside subscibe could lead to issue Attempt to use a destroyed view: detectChanges

To solve it you need to unsubscribe before you destroy the component, so the full code will be like:

import {Component, OnInit, ChangeDetectorRef, OnDestroy} from 'angular2/core';

export class RecentDetectionComponent implements OnInit, OnDestroy {

    recentDetections: Array<RecentDetection>;
    private timerObserver: Subscription;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        this.timerObserver = timer.subscribe(() => this.getRecentDetections());
    }

    ngOnDestroy() {
        this.timerObserver.unsubscribe();
    }

}

You can use a file browser with an backup function, for example the ES File Explorer Long tap a item and select create backup

I was facing the same issue with jenkins ssh slave 'jenkinsci/ssh-slave'. However, my case was a bit complicated because it was necessary to pass an argument which contained spaces. I've managed to do it like below (entrypoint in dockerfile is in exec form):

command: ["some argument with space which should be treated as one"]

A one liner that takes into account empty lists would be:

T lastItem = list.size() == 0 ? null : list.get(list.size() - 1);

Or if you don't like null values (and performance isn't an issue):

Optional<T> lastItem = list.stream().reduce((first, second) -> second);

I wanted to throw this up for good measure. I think the way @micahtan posted is preferred.

typeof(MyProgram).Name

This will give you a list of a single group, and the members of each group.

param
(   
    [Parameter(Mandatory=$true,position=0)]
    [String]$GroupName
)

import-module activedirectory

# optional, add a wild card..
# $groups = $groups + "*"

$Groups = Get-ADGroup -filter {Name -like $GroupName} | Select-Object Name

ForEach ($Group in $Groups)
   {write-host " "
    write-host "$($group.name)"
    write-host "----------------------------"

    Get-ADGroupMember -identity $($groupname) -recursive | Select-Object samaccountname

 }
write-host "Export Complete"

If you want the friendly name, or other details, add them to the end of the select-object query.

Div is a block element and span is an inline element and its width depends upon the content of it self where div does not

I've had this problem twice. The first problem was fixed using the marked answer on this page (thank you for that). However, the second time proved a bit more difficult.

I found that in my httpd-vhosts.conf file that I made a mistake when assigning the document root to a domain name. Fixing this solved my problem. It is well worth checking (or even reverting to a blank copy) your httpd-vhosts.conf file for any errors and typo's.

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

Preserve the name of the column and avoid extra column addition by using the same name as input column:

changedTypedf = joindf.withColumn("show", joindf["show"].cast(DoubleType()))

How about using good(?) old goto?

:loop

echo Ooops

goto loop

See also this for a more useful example.

Raw Javascript can accomplish the same thing pretty quickly also:

document.getElementById("myElement").onclick = function() { return false; } 

I prefer to use BINARY(32) since it's the optimized way!

You can place in that 32 hex digits from (00 to FF).

Therefore BINARY(32)!

Your call_python_file.php should look like this:

<?php
    $item='Everything is awesome!!';
    $tmp = exec("py.py $item");
    echo $tmp;
?>

This executes the python script and outputs the result to the browser. While in your python script the (sys.argv[1:]) variable will bring in all your arguments. To display the argv as a string for wherever your php is pulling from so if you want to do a text area:

import sys

list1 = ' '.join(sys.argv[1:])

def main():
  print list1

if __name__ == '__main__':
    main()

While converting a STD class object to array.Cast the object to array by using array function of php.

Try out with following code snippet.

/*** cast the object ***/    
foreach($stdArray as $key => $value)
{
    $stdArray[$key] = (array) $value;
}   
/*** show the results ***/  
print_r( $stdArray );

We can also remove it using match

var fileName = $('input:file').val().match(/[^\\/]*$/)[0];
$('#file-name').val(fileName);

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.

public object Current;
public void Reset();
public bool MoveNext();

I'd suggest marking the Hibernate DAO class with @Primary, i.e. (assuming you used @Repository on HibernateDeviceDao):

@Primary
@Repository
public class HibernateDeviceDao implements DeviceDao

This way it will be selected as the default autowire candididate, with no need to autowire-candidate on the other bean.

Also, rather than using @Autowired @Qualifier, I find it more elegant to use @Resource for picking specific beans, i.e.

@Resource(name="jdbcDeviceDao")
DeviceDao deviceDao;

You can't. If you have a method called isBiggerThanMaxLong(long) it should always return false.

If you were to increment the bits of Long.MAX_VALUE, the next value should be Long.MIN_VALUE. Read up on twos-complement and that should tell you why.

String source = "testString";
byte[] byteArray = source.getBytes(encoding); 

You can foreach and do the same with all the strings in the array.

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

You can change time() to now() for it to work

from datetime import datetime, timedelta
datetime.now() + timedelta(hours=1)

Here is some better usage of java for scanner

try(Scanner sc = new Scanner(System.in)) {

    //Use sc as you need

} catch (Exception e) {

        //  handle exception

}

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

      } 
   }
}

A more readable version of the ternary might look like:

var x = this.dealer;
alert(t < 1 || t > 11
  ? 'none'
    : t < 5
  ? 'less than five'
    : t <= 8
  ? 'between 5 and 8'
  : 'Between 9 and 11');

I've updated polkovnikov.ph solution to React 16 / ES6 with enhancements like touch handling and snapping to a grid which is what I need for a game. Snapping to a grid alleviates the performance issues.

import React from 'react';
import ReactDOM from 'react-dom';

Please use following php function to convert php stdClass to array

get_object_vars($data)

No. It's not possible.

Example:

import random

def gen(n):
    for i in xrange(n):
        if random.randint(0, 1) == 0:
            yield i

iterator = gen(10)

Length of iterator is unknown until you iterate through it.

Those access modifiers specify where your members are visible. You should probably read this up. Take the link given by IainMH as a starting point.

Static members are one per class and not one per instance.

string.join the list values separated by commas, and use the format operator to form a query string.

myquery = "select name from studens where id in (%s)" % ",".join(map(str,mylist))

(Thanks, blair-conrad)

You can use checkout or co

$ svn co http://example.com/svn/app-name directory-name

Some short codes:-

1. checkout (co)
2. commit (ci)
3. copy (cp)
4. delete (del, remove,rm)
5. diff (di)

You can use substr:

echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'

Here I would like to present another alternative to Flatten function. This may help to understand what is going on internally. The alternative method adds three more code lines. Instead of using

#==========================================Build a Model
model = tf.keras.models.Sequential()

model.add(keras.layers.Flatten(input_shape=(28, 28, 3)))#reshapes to (2352)=28x28x3
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
model.add(keras.layers.Dense(128,activation=tf.nn.relu))
model.add(keras.layers.Dense(2,activation=tf.nn.softmax))

model.build()
model.summary()# summary of the model

we can use

    #==========================================Build a Model
    tensor = tf.keras.backend.placeholder(dtype=tf.float32, shape=(None, 28, 28, 3))
    
    model = tf.keras.models.Sequential()
    
    model.add(keras.layers.InputLayer(input_tensor=tensor))
    model.add(keras.layers.Reshape([2352]))
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
    model.add(keras.layers.Dense(128,activation=tf.nn.relu))
    model.add(keras.layers.Dense(2,activation=tf.nn.softmax))
    
    model.build()
    model.summary()# summary of the model

In the second case, we first create a tensor (using a placeholder) and then create an Input layer. After, we reshape the tensor to flat form. So basically,

Create tensor->Create InputLayer->Reshape == Flatten

Flatten is a convenient function, doing all this automatically. Of course both ways has its specific use cases. Keras provides enough flexibility to manipulate the way you want to create a model.

There is a nice explanation in Numpy docs: https://docs.scipy.org/doc/numpy-1.15.1/reference/generated/numpy.random.RandomState.html it refers to Mersenne Twister pseudo-random number generator. More details on the algorithm here: https://en.wikipedia.org/wiki/Mersenne_Twister

You can allow the Docker user (here: root) to access the X11 display:

XSOCK=/tmp/.X11-unix
xhost +SI:localuser:root 
docker run -t -i --rm -v $XSOCK:$XSOCK:ro -e DISPLAY=unix$(DISPLAY) image 
xhost -SI:localuser:root

Use this Layout in your xml file

<LinearLayout
  android:id="@+id/contacts_type"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:visibility="gone">
</LinearLayout>

Define your layout in .class file

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);

Now if you want to display this layout just write

 linearLayout.setVisibility(View.VISIBLE);

and if you want to hide layout just write

 linearLayout.setVisibility(View.INVISIBLE);

I always love using the command line and have user friendly tools (with GUI) at my hand. Best of both worlds. Here is how I do it to compare two commits in Git.

You can show the diff between two commits like the following.

Edit your git config file in a TEXT EDITOR:

git config --global -e 

Set up a proper diff tool (user friendly) like Meld like this in Windows in the Git config file:

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

Meld can be installed using Chocolatey like this from the COMMAND LINE:

choco install meld

Let's define a shell function to help us compare two sha-s (commits) under [alias] in the TEXT EDITOR:

[alias]
showchangesbetween = "!w() { git difftool \"$1\" \"$2\" --dir-diff --ignore-all-space; }; w"

To compare the commits with the help of Meld (or your other favorite diff tool, just type at the COMMAND LINE:

git showchangesbetween somesha123 somesha456

The commit sha-s are easily visible typing

 git log 

for example.

This one shows SQL that is currently "ACTIVE":-

select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:

select
  object_name, 
  object_type, 
  session_id, 
  type,         -- Type or system/user lock
  lmode,        -- lock mode in which session holds lock
  request, 
  block, 
  ctime         -- Time since current mode was granted
from
  v$locked_object, all_objects, v$lock
where
  v$locked_object.object_id = all_objects.object_id AND
  v$lock.id1 = all_objects.object_id AND
  v$lock.sid = v$locked_object.session_id
order by
  session_id, ctime desc, object_name
/

This is a good one for finding long operations (e.g. full table scans). If it is because of lots of short operations, nothing will show up.

COLUMN percent FORMAT 999.99 

SELECT sid, to_char(start_time,'hh24:mi:ss') stime, 
message,( sofar/totalwork)* 100 percent 
FROM v$session_longops
WHERE sofar/totalwork < 1
/

I hacked together some tool which attaches into a running Python process and injects some code to get a Python shell.

See here: https://github.com/albertz/pydbattach

You don't need to use display:inline to achieve this:

.inline { 
    border: 1px solid red;
    margin:10px;
    float:left;/*Add float left*/
    margin :10px;
}

You can use float-left.

Using float:left is best way to place multiple div elements in one line. Why? Because inline-block does have some problem when is viewed in IE older versions.

fiddle

class FooObservableCollection : ObservableCollection<Foo>
{
    protected override void InsertItem(int index, Foo item)
    {
        base.Add(index, Foo);

        if (this.CollectionChanged != null)
            this.CollectionChanged(this, new NotifyCollectionChangedEventArgs (NotifyCollectionChangedAction.Add, item, index);
    }
}

var collection = new FooObservableCollection();
collection.CollectionChanged += CollectionChanged;

collection.Add(new Foo());

void CollectionChanged (object sender, NotifyCollectionChangedEventArgs e)
{
    Foo newItem = e.NewItems.OfType<Foo>().First();
}

You can access the namespace's dictionary with vars():

>>> import argparse
>>> args = argparse.Namespace()
>>> args.foo = 1
>>> args.bar = [1,2,3]
>>> d = vars(args)
>>> d
{'foo': 1, 'bar': [1, 2, 3]}

You can modify the dictionary directly if you wish:

>>> d['baz'] = 'store me'
>>> args.baz
'store me'

Yes, it is okay to access the __dict__ attribute. It is a well-defined, tested, and guaranteed behavior.

The following works for me:

composer update --no-scripts

You can set the line size as per the width of the window and set wrap off using the following command.

set linesize 160;
set wrap off;

I have used 160 as per my preference you can set it to somewhere between 100 - 200 and setting wrap will not your data and it will display the data properly.

Use following in your CSS

div {
    -webkit-transform: rotate(90deg); /* Safari and Chrome */
    -moz-transform: rotate(90deg);   /* Firefox */
    -ms-transform: rotate(90deg);   /* IE 9 */
    -o-transform: rotate(90deg);   /* Opera */
    transform: rotate(90deg);
} 

Instead of setting the @JsonSerialize on each member or getter you can configure a module that use a custome serializer for a certain type:

SimpleModule module = new SimpleModule();
module.addSerializer(BigInteger.class, new ToStringSerializer());
objectMapper.registerModule(module);

In the above example, I used the to string serializer to serialize BigIntegers (since javascript can not handle such numeric values).

You can filter using index of array.

var months = ['Jan', 'March', 'April', 'June'];_x000D_
months = months.filter((month,idx) => idx < 2)_x000D_
console.log(months);

    Dim x As Integer = 0
    Dim y As Integer = 0
    Dim k = 0
    Dim l = 0
    Dim bm As New Bitmap(p1.Image)
    Dim om As New Bitmap(p1.Image.Width, p1.Image.Height)
    Dim r, g, b As Byte
    Do While x < bm.Width - 1
        y = 0
        l = 0
        Do While y < bm.Height - 1
            r = 255 - bm.GetPixel(x, y).R
            g = 255 - bm.GetPixel(x, y).G
            b = 255 - bm.GetPixel(x, y).B
            om.SetPixel(k, l, Color.FromArgb(r, g, b))
            y += 3
            l += 1
        Loop
        x += 3
        k += 1
    Loop
    p2.Image = om

Note that SimpleDateFormat format pattern Z is for RFC 822 time zone and pattern X is for ISO 8601 (this standard supports single letter time zone names like Z for Zulu).

So new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX") produces a format that can parse both "2013-03-11T01:38:18.309Z" and "2013-03-11T01:38:18.309+0000" and will give you the same result.

Unfortunately, as far as I can tell, you can't get this format to generate the Z for Zulu version, which is annoying.

I actually have more trouble on the JavaScript side to deal with both formats.

This worked for me Option + left-arrow or Option + right-arrow for moving the cursor to the start or end of the line.

Mac Os Version: Catalina

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

The init func runs first and then main. It's used for setting something first before your program runs, for example:

Accessing a template, Running the program using all cores, Checking the Goos and arch etc...

A pattern that I particularly like is to combine nested classes with the factory pattern:

public abstract class BankAccount
{
  private BankAccount() {} // prevent third-party subclassing.
  private sealed class SavingsAccount : BankAccount { ... }
  private sealed class ChequingAccount : BankAccount { ... }
  public static BankAccount MakeSavingAccount() { ... }
  public static BankAccount MakeChequingAccount() { ... }
}

By nesting the classes like this, I make it impossible for third parties to create their own subclasses. I have complete control over all the code that runs in any bankaccount object. And all my subclasses can share implementation details via the base class.

The main difference that you need to know is .map() returns a new array while .forEach() doesn't. That is why you see that difference in the output. .forEach() just operates on every value in the array.

Read up:

• Array.prototype.forEach() - JavaScript | MDN
• Array.prototype.map() - JavaScript | MDN

You might also want to check out: - Array.prototype.every() - JavaScript | MDN

switch() is a powerful and standard way of implementing state machines in C, but it can decrease maintainability down if you have a large number of states. Another common method is to use function pointers to store the next state. This simple example implements a set/reset flip-flop:

/* Implement each state as a function with the same prototype */
void state_one(int set, int reset);
void state_two(int set, int reset);

/* Store a pointer to the next state */
void (*next_state)(int set, int reset) = state_one;

/* Users should call next_state(set, reset). This could
   also be wrapped by a real function that validated input
   and dealt with output rather than calling the function
   pointer directly. */

/* State one transitions to state one if set is true */
void state_one(int set, int reset) {
    if(set)
        next_state = state_two;
}

/* State two transitions to state one if reset is true */
void state_two(int set, int reset) {
    if(reset)
        next_state = state_one;
}

Combining @nawfal & @Kobi suggestions:

namespace Extensions
{
    /// <summary> Useful in number of places that return an empty byte array to avoid unnecessary memory allocation. </summary>
    public static class Array<T>
    {
        public static readonly T[] Empty = new T[0];
    }
}

Usage example:

Array<string>.Empty

UPDATE 2019-05-14

(credits to @Jaider ty)

Better use .Net API:

public static T[] Empty<T> ();

I faced a similar problem. I tried everything with ports, hosts and config files.But nothing helped.

I checked apache error logs. They showed the following error

(OS 10038)An operation was attempted on something that is not a socket.  : AH00332: winnt_accept: getsockname error on listening socket, is IPv6 available?

Finally this is what solved my problem.

1) Goto command prompt and run it in administrative mode. In windows 7 you can do it by typing cmd in run and then pressing ctrl+shift+enter

2) run the following command: netsh winsock reset

3) Restart the system

A more modern solution might be to use css variables and calc. calc is widely supported but variables is not yet in IE11 (polyfills available).

:root {
  box-width: 100px;
  border-width: 1px;
}

#box {
  width: calc(var(--box-width) - var(--border-width));
}

Although this does use some calculations, which the original questions was looking to avoid. I think this is an ok time to use calculations as they are controlled by the css itself. It also has no need for additional markup or misappropriating other css properties that may be needed later on.

This solution is only really useful if a fixed height isn't needed.

Intel has a peach of an article on this. It's all the same driver. It's just a Device ID mismatch in the Inf file which can be edited, or Windows forced to Install the driver we point it to.

If you are looking for the opposite to get a date from a weeknumber i found a solution online and changed it slightly:

Function fnDateFromWeek(iYear As Integer, iWeek As Integer, iWeekDday As Integer)
  ' get the date from a certain day in a certain week in a certain year
  fnDateFromWeek = DateSerial(iYear, 1, (iWeek * 7) _
          + iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
End Function

I took the formular from asap-utilities.com/ and changed

DateSerial(iYear, 1, ((iWeek - 1) * 7) 

to

DateSerial(iYear, 1, (iWeek * 7)

Update

It seems that at least for germany the formular works not as expected for the leap year 2016 so i changed it to this

Function fnDateFromWeek(iYear As Integer, iWeek As Integer, iWeekDday As Integer)
' get the date from a certain day in a certain week in a certain year
  
    If isLeapYear(iYear) Then
        curDate = DateSerial(iYear, 1, ((iWeek) * 7) _
          + iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
    Else
        curDate = DateSerial(iYear, 1, ((iWeek - 1) * 7) _
          + iWeekDday - Weekday(DateSerial(iYear, 1, 1)) + 1)
    End If
    fnDateFromWeek = curDate
End Function

Since 2016 hardcoded is not ideal you could check if a year is a leap year with this function

Function isLeapYear(iYear As Integer) As Boolean

    If (Month(DateSerial(iYear, 2, 29)) = 2) Then
        isLeapYear = True
    Else
        isLeapYear = False
    End If
    
End Function

For a non-leap-year DateSerial(iYear,2 ,29) returns 1st of march

This may still be wrong but my limited test gave the expected results:

Sub TestExample()
   Debug.Print Format(fnDateFromWeek(2014, 48, 2), "ddd dd mmm yyyy") ' mo 24 Nov 2014
   Debug.Print Format(fnDateFromWeek(2015, 11, 6), "ddd dd-mmm-yyyy") ' fr 13 Mar 2015
   Debug.Print Format(fnDateFromWeek(2016, 36, 2), "ddd dd-mmm-yyyy") ' Mo 05 Sep 2015
End Sub

The right way is:

db.users.find({awards: {$elemMatch: {award:'National Medal', year:1975}}})

$elemMatch allows you to match more than one component within the same array element.

Without $elemMatch mongo will look for users with National Medal in some year and some award in 1975s, but not for users with National Medal in 1975.

See MongoDB $elemMatch Documentation for more info. See Read Operations Documentation for more information about querying documents with arrays.

It's the ternary form of the if-else operator. The above statement basically reads like this:

if ($add_review) then {
    return FALSE; //$add_review evaluated as True
} else {
    return $arg //$add_review evaluated as False
}

As Commodore Jaeger alluded to, I don't think any of the other answers actually answer this question; the question asks how to repeat a string, not a character.

While the answer given by Commodore is correct, it is quite inefficient. Here is a faster implementation, the idea is to minimise copying operations and memory allocations by first exponentially growing the string:

#include <string>
#include <cstddef>

std::string repeat(std::string str, const std::size_t n)
{
    if (n == 0) {
        str.clear();
        str.shrink_to_fit();
        return str;
    } else if (n == 1 || str.empty()) {
        return str;
    }
    const auto period = str.size();
    if (period == 1) {
        str.append(n - 1, str.front());
        return str;
    }
    str.reserve(period * n);
    std::size_t m {2};
    for (; m < n; m *= 2) str += str;
    str.append(str.c_str(), (n - (m / 2)) * period);
    return str;
}

We can also define an operator* to get something closer to the Python version:

#include <utility>

std::string operator*(std::string str, std::size_t n)
{
    return repeat(std::move(str), n);
}

On my machine this is around 10x faster than the implementation given by Commodore, and about 2x faster than a naive 'append n - 1 times' solution.

/*for (Song s: songList){
    System.out.println(s + "," + songList.indexOf(s); 
}*/

it is possible in linked list.

you have to make toString() in song class. if you don't it will print out reference of the song.

probably irrelevant for you by now. ^_^

The below line of code would do it for you.

find / -name index.html

However, on most Linux servers, your files will be located in /var/www or in your user directory folder /home/(user) depending on how you have it set up. If you're using a control panel, most likely it'll be under your user folder.

From Netbeans 8.1 - there is an "Import from ZIP" option.

Go to Main Menu -> File -> Import Project -> from ZIP.

Browse your .ZIP file's location via Browse button.

If you have Java project depending on external Libraries, Netbeans will highlight & ask for "Resolving problems" in project, click on resolve, provide location in your file system containing required library files .e.g JARs etc & you will be good to go.

I found all the previous answers too much complicated. I had the need to store an array of some ints as a property, and found the ObjC requirement of using a NSArray an unneeded complication of my software.

So I used this:

typedef struct my10ints {
    int arr[10];
} my10ints;

@interface myClasss : NSObject

@property my10ints doubleDigits;

@end

This compiles cleanly using Xcode 6.2.

My intention was to use it like this:

myClass obj;
obj.doubleDigits.arr[0] = 4;

HOWEVER, this does not work. This is what it produces:

int i = 4;
myClass obj;
obj.doubleDigits.arr[0] = i;
i = obj.doubleDigits.arr[0];
// i is now 0 !!!

The only way to use this correctly is:

int i = 4;
myClass obj;
my10ints ints;
ints = obj.doubleDigits;
ints.arr[0] = i;
obj.doubleDigits = ints;
i = obj.doubleDigits.arr[0];
// i is now 4

and so, defeats completely my point (avoiding the complication of using a NSArray).

I had the same problem. So here is what i did

1. reinstalled the device driver
2. changed the USB computer connection from MTP to Mass storage(UMS)

And it worked.

While I appreciate you believe absolute paths is not an option, it is a better option than relative paths and updating the PHP include path.

Use absolute paths with an constant you can set based on environment.

if (is_production()) {
    define('ROOT_PATH', '/some/production/path');
}
else {
    define('ROOT_PATH', '/root');
}

include ROOT_PATH . '/connect.php';

As commented, ROOT_PATH could also be derived from the current path, $_SERVER['DOCUMENT_ROOT'], etc.

PsSuspend, as mentioned by Vadzim, even suspends/resumes a process by its name, not only by pid.

I use both PsSuspend and PsList (another tool from the PsTools suite) in a simple toggle script for the OneDrive process: if I need more bandwidth, I suspend the OneDrive sync, afterwards I resume the process by issuing the same mini script:

PsList -d onedrive|find/i "suspend" && PsSuspend -r onedrive || PsSuspend onedrive

PsSuspend command line utility from SysInternals suite. It suspends / resumes a process by its id.

I had trouble with the other DatabaseHelpers regarding this problem, not sure why.
This is what worked for me:

    this.context = context;
    this.assetPath = assetPath;
    this.dbPath = "/data/data/"
        + context.getApplicationContext().getPackageName() + "/databases/"
        + dbName;
    checkExists();
  }

      dbFile.getParentFile().mkdirs();
      copyStream(context.getAssets().open(assetPath), new FileOutputStream(
          dbFile));

      Log.i(TAG, assetPath + " has been copied to " + dbFile.getAbsolutePath());
