Here's a one line solution:

array_shift((explode('.', $_SERVER['HTTP_HOST'])));

Or using your example:

array_shift((explode('.', 'en.example.com')));

EDIT: Fixed "only variables should be passed by reference" by adding double parenthesis.

EDIT 2: Starting from PHP 5.4 you can simply do:

explode('.', 'en.example.com')[0];

Try moving the order by after group by:

var groupByReference = (from m in context.Measurements
                        group m by new { m.Reference } into g
                        order by g.Avg(i => i.CreationTime)
                        select g).Take(numOfEntries).ToList();

The easiest is

as @greggo pointed out

string="mystring";
string[:-1]

Here's my current solution to run any code remotely on a given machine or list of machines asynchronously with logging, too!

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

You may also use:

request.POST.get('section','') # => [39]
request.POST.get('MAINS','') # => [137] 
request.GET.get('section','') # => [39]
request.GET.get('MAINS','') # => [137]

Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).

If you are using hibernate as your JPA provider you can use the annotation @OnDelete. This annotation will add to the relation the trigger ON DELETE CASCADE, which delegates the deletion of the children to the database.

Example:

public class Parent {
   
        @Id
        private long id;

}


public class Child {
        
        @Id
        private long id;
  
        @ManyToOne
        @OnDelete(action = OnDeleteAction.CASCADE)
        private Parent parent;
}
     

With this solution a unidirectional relationship from the child to the parent is enough to automatically remove all children. This solution does not need any listeners etc. Also a JPQL query like DELETE FROM Parent WHERE id = 1 will remove the children.

XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.

1. Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.

2. Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.

3. Try connecting to the server (localhost, port 21).

        // Create the alert controller
        let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)

        // Create the actions
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
            UIAlertAction in
            NSLog("OK Pressed")
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) {
            UIAlertAction in
            NSLog("Cancel Pressed")
        }

        // Add the actions
        alertController.addAction(okAction)
        alertController.addAction(cancelAction)

        // Present the controller
        self.present(alertController, animated: true, completion: nil)

(1) This just happened to me, and I thought it was interesting how it happened. Basically I had copied the folder to a new location and modified it, forgetting that it would bring along all the hidden .svn directories. Once you realize how it happens it is easier to avoid in the future.

(2) Removing the .svn directories is the solution, but you have to do it recursively all the way down the directory tree. The easiest way to do that is:

find troublesome_folder -name .svn -exec rm -rf {} \;

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

Slonik is an alternative to answers proposed by Kuberchaun and Vitaly.

Slonik implements safe connection handling; you create a connection pool and connection opening/handling is handled for you.

import {
  createPool,
  sql
} from 'slonik';

const pool = createPool('postgres://user:password@host:port/database');

return pool.connect((connection) => {
  // You are now connected to the database.
  return connection.query(sql`SELECT foo()`);
})
  .then(() => {
    // You are no longer connected to the database.
  });

postgres://user:password@host:port/database is your connection string (or more canonically a connection URI or DSN).

The benefit of this approach is that your script ensures that you never accidentally leave hanging connections.

Other benefits for using Slonik include:

• Built-in assertions and type safety.
• Safe transaction handling.
• Safe value interpolation.
• Transaction nesting.
• Detail logging.
• Asynchronous stack trace resolution.

Simply you can use padding-top and padding-bottom on a td element.

Unit can anything from this list:

Demo Code:

td_x000D_
{_x000D_
  padding-top: 10px;_x000D_
  padding-bottom: 10px;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <th>Firstname</th>_x000D_
    <th>Lastname</th>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Peter</td>_x000D_
    <td>Griffin</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Lois</td>_x000D_
    <td>Griffin</td>_x000D_
  </tr>_x000D_
</table>

1. Monolithic kernel design is much older than the microkernel idea, which appeared at the end of the 1980's.

2. Unix and Linux kernels are monolithic, while QNX, L4 and Hurd are microkernels. Mach was initially a microkernel (not Mac OS X), but later converted into a hybrid kernel. Minix (before version 3) wasn't a pure microkernel because device drivers were compiled as part of the kernel.

3. Monolithic kernels are usually faster than microkernels. The first microkernel Mach was 50% slower than most monolithic kernels, while later ones like L4 were only 2% or 4% slower than the monolithic designs.

4. Monolithic kernels are big in size, while microkernels are small in size - they usually fit into the processor's L1 cache (first generation microkernels).

5. In monolithic kernels, the device drivers reside in the kernel space while in the microkernels the device drivers are user-space.

6. Since monolithic kernels' device drivers reside in the kernel space, monolithic kernels are less secure than microkernels, and failures (exceptions) in the drivers may lead to crashes (displayed as BSODs in Windows). Microkernels are more secure than monolithic kernels, hence more often used in military devices.

7. Monolithic kernels use signals and sockets to implement inter-process communication (IPC), microkernels use message queues. 1st gen microkernels didn't implement IPC well and were slow on context switches - that's what caused their poor performance.

8. Adding a new feature to a monolithic system means recompiling the whole kernel or the corresponding kernel module (for modular monolithic kernels), whereas with microkernels you can add new features or patches without recompiling.

What am I doing incorrectly?

You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.

How can I receive a json object in the controller?

View:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>

var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });

<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>

Controller:

public void PostRawJson(string json)
{
    var order = System.Web.Helpers.Json.Decode(json);
    var orderDate = order.OrderDate;
    var secondOrderId = order.Item[1].Id;
}

In ES2015 a.k.a ES6 version of JavaScript, a new datatype called Map is introduced.

let map = new Map([["key1", "value1"], ["key2", "value2"]]);
map.get("key1"); // => value1

        $('#top').click(function () {
            $('body,html').animate({
                scrollTop: 0
            }, 800);
            return false;

ID=$(docker build -t creack/node .) doesn't work for me since ID will contain the output from the build.

SO I'm using this small BASH script:

#!/bin/bash

set -o pipefail

IMAGE=...your image name...
VERSION=...the version...

docker build -t ${IMAGE}:${VERSION} . | tee build.log || exit 1
ID=$(tail -1 build.log | awk '{print $3;}')
docker tag $ID ${IMAGE}:latest

docker images | grep ${IMAGE}

docker run --rm ${IMAGE}:latest /opt/java7/bin/java -version

With bashj ( https://sourceforge.net/projects/bashj/ ) , you should be able to run not only multiple processes (the way others suggested) but also multiple Threads in one JVM controlled from your script. But of course this requires a java JDK. Threads consume less resource than processes.

Here is a working code:

#!/usr/bin/bashj

#!java

public static int cnt=0;

private static void loop() {u.p("java says cnt= "+(cnt++));u.sleep(1.0);}

public static void startThread()
{(new Thread(() ->  {while (true) {loop();}})).start();}

#!bashj

j.startThread()

while [ j.cnt -lt 4 ]
do
  echo "bash views cnt=" j.cnt
  sleep 0.5
done

The generic view of a loop is

for (initialization; condition; increment-decrement){}

The first part initializes the code. The second part is the condition that will continue to run the loop as long as it is true. The last part is what will be run after each iteration of the loop. The last part is typically used to increment or decrement a counter, but it doesn't have to.

To create a table on the fly us this syntax:

SELECT *
INTO A
FROM dbo.myView

Modify your estimated population function to take a growth argument of type float. Then you can call the growthRate function with your birthRate and deathRate and use the return value as the input for grown into estimatedPopulation.

float growthRate (float birthRate, float deathRate)     
{    
    return ((birthRate) - (deathRate));    
}

int estimatedPopulation (int currentPopulation, float growth)
{
    return ((currentPopulation) + (currentPopulation) * (growth / 100);
}

// main.cpp
int currentPopulation = 100;
int births = 50;
int deaths = 25;
int population = estimatedPopulation(currentPopulation, growthRate(births, deaths));

For offsprings.

How I managed to add russian language to fpdf on my Linux machine:

1) Go to http://www.fpdf.org/makefont/ and convert your ttf font(for example AerialRegular.ttf) into 2 files using ISO-8859-5 encoding: AerialRegular.php and AerialRegular.z

2) Put these 2 files into fpdf/font directory

3) Use it in your code:

$pdf = new \FPDI();
    $pdf->AddFont('ArialMT','','ArialRegular.php');
    $pdf->AddPage();
    $tplIdx = $pdf->importPage(1);
    $pdf->useTemplate($tplIdx, 0, 0, 211, 297); //width and height in mms
    $pdf->SetFont('ArialMT','',35);
    $pdf->SetTextColor(255,0,0);
    $fullName = iconv('UTF-8', 'ISO-8859-5', '???????');
    $pdf->SetXY(60, 54);
    $pdf->Write(0, $fullName);

Along the same lines as SCFrench's answer, but with a more C# style spin..

I would (and often do) make a class containing multiple static methods. For example:

classdef Statistics

    methods(Static)
        function val = MyMean(data)
            val = mean(data);
        end

        function val = MyStd(data)
            val = std(data);
        end
    end

end

As the methods are static you don't need to instansiate the class. You call the functions as follows:

data = 1:10;

mean = Statistics.MyMean(data);
std = Statistics.MyStd(data);     

First to install your app:

adb install -r path\ProjectName.apk

The great thing about the -r is it works even if it wasn’t already installed.

To launch MainActivity, so you can launch it like:

adb shell am start -n com.other.ProjectName/.MainActivity

The following example uses the GroupBy method to return objects that are grouped by PersonID.

var results = persons.GroupBy(x => x.PersonID)
              .Select(x => (PersonID: x.Key, Cars: x.Select(p => p.car).ToList())
              ).ToList();

Or

 var results = persons.GroupBy(
               person => person.PersonID,
               (key, groupPerson) => (PersonID: key, Cars: groupPerson.Select(x => x.car).ToList()));

Or

 var results = from person in persons
               group person by person.PersonID into groupPerson
               select (PersonID: groupPerson.Key, Cars: groupPerson.Select(x => x.car).ToList());

Or you can use ToLookup, Basically ToLookup uses EqualityComparer<TKey>.Default to compare keys and do what you should do manually when using group by and to dictionary. i think it's excuted inmemory

 ILookup<int, string> results = persons.ToLookup(
            person => person.PersonID,
            person => person.car);

In case anyone wishes to do this with bootstrap, version 4 offers the following:

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Where property is one of:

m - for classes that set margin
p - for classes that set padding

Where sides is one of:

t - for classes that set margin-top or padding-top
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
auto - for classes that set the margin to auto

For example:

.mt-0 {
  margin-top: 0 !important;
}

.ml-1 {
  margin-left: ($spacer * .25) !important;

It is for C#

If you are doing this in a virtual environment whether using Visual Studio or otherwise, try easy_install MySQL-python

This is the solution I came up with:

import time
from threading import Thread
from threading import Lock

def myfunc(i, mutex):
    mutex.acquire(1)
    time.sleep(1)
    print "Thread: %d" %i
    mutex.release()


mutex = Lock()
for i in range(0,10):
    t = Thread(target=myfunc, args=(i,mutex))
    t.start()
    print "main loop %d" %i

Output:

main loop 0
main loop 1
main loop 2
main loop 3
main loop 4
main loop 5
main loop 6
main loop 7
main loop 8
main loop 9

In general, in C++ functions have to be declared before you call them. So sometime before the definition of getSkewNormal(), the compiler needs to see the declaration:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

Mostly what people do is put all the declarations (only) in the header file, and put the actual code -- the definitions of the functions and methods -- into a separate source (*.cc or *.cpp) file. This neatly solves the problem of needing all the functions to be declared.

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

From the comments of php's date() manual page:

<?php $mysqltime = date ('Y-m-d H:i:s', $phptime); ?>

You had the 'Y' correct - that's a full year, but 'M' is a three character month, while 'm' is a two digit month. Same issue with 'D' instead of 'd'. 'G' is a 1 or 2 digit hour, where 'H' always has a leading 0 when needed.

If you are using Ruby 1.9.2 or later, you can use URI.encode_www_form if you don't need arrays.

E.g. (from the Ruby docs in 1.9.3):

URI.encode_www_form([["q", "ruby"], ["lang", "en"]])
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => "ruby", "lang" => "en")
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => ["ruby", "perl"], "lang" => "en")
#=> "q=ruby&q=perl&lang=en"
URI.encode_www_form([["q", "ruby"], ["q", "perl"], ["lang", "en"]])
#=> "q=ruby&q=perl&lang=en"

You'll notice that array values are not set with key names containing [] like we've all become used to in query strings. The spec that encode_www_form uses is in accordance with the HTML5 definition of application/x-www-form-urlencoded data.

It will prints the string"something" three times.

JLabel[] labels = {new JLabel(), new JLabel(), new JLabel()};

   label.setText("something");  

 panel.add(label);

This is a DevExpress specific answer based on the top-voted answer by Gregor S. (currently it has 128 votes).

This means we can keep the styling consistent across the entire application:

Unfortunately, the original answer doesn't work with a ComboBoxEdit from DevExpress without some modifications.

First, the XAML for the ComboBoxEdit:

<dxe:ComboBoxEdit ItemsSource="{Binding Source={xamlExtensions:XamlExtensionEnumDropdown {x:myEnum:EnumFilter}}}"
    SelectedItem="{Binding BrokerOrderBookingFilterSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
    DisplayMember="Description"
    MinWidth="144" Margin="5" 
    HorizontalAlignment="Left"
    IsTextEditable="False"
    ValidateOnTextInput="False"
    AutoComplete="False"
    IncrementalFiltering="True"
    FilterCondition="Like"
    ImmediatePopup="True"/>

Needsless to say, you will need to point xamlExtensions at the namespace that contains the XAML extension class (which is defined below):

xmlns:xamlExtensions="clr-namespace:XamlExtensions"

And we have to point myEnum at the namespace that contains the enum:

xmlns:myEnum="clr-namespace:MyNamespace"

Then, the enum:

namespace MyNamespace
{
    public enum EnumFilter
    {
        [Description("Free as a bird")]
        Free = 0,

        [Description("I'm Somewhat Busy")]
        SomewhatBusy = 1,

        [Description("I'm Really Busy")]
        ReallyBusy = 2
    }
}

The problem in with the XAML is that we can't use SelectedItemValue, as this throws an error as the setter is unaccessable (bit of an oversight on your part, DevExpress). So we have to modify our ViewModel to obtain the value directly from the object:

private EnumFilter _filterSelected = EnumFilter.All;
public object FilterSelected
{
    get
    {
        return (EnumFilter)_filterSelected;
    }
    set
    {
        var x = (XamlExtensionEnumDropdown.EnumerationMember)value;
        if (x != null)
        {
            _filterSelected = (EnumFilter)x.Value;
        }
        OnPropertyChanged("FilterSelected");
    }
}

For completeness, here is the XAML extension from the original answer (slightly renamed):

namespace XamlExtensions
{
    /// <summary>
    ///     Intent: XAML markup extension to add support for enums into any dropdown box, see http://bit.ly/1g70oJy. We can name the items in the
    ///     dropdown box by using the [Description] attribute on the enum values.
    /// </summary>
    public class XamlExtensionEnumDropdown : MarkupExtension
    {
        private Type _enumType;


        public XamlExtensionEnumDropdown(Type enumType)
        {
            if (enumType == null)
            {
                throw new ArgumentNullException("enumType");
            }

            EnumType = enumType;
        }

        public Type EnumType
        {
            get { return _enumType; }
            private set
            {
                if (_enumType == value)
                {
                    return;
                }

                var enumType = Nullable.GetUnderlyingType(value) ?? value;

                if (enumType.IsEnum == false)
                {
                    throw new ArgumentException("Type must be an Enum.");
                }

                _enumType = value;
            }
        }

        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            var enumValues = Enum.GetValues(EnumType);

            return (
                from object enumValue in enumValues
                select new EnumerationMember
                       {
                           Value = enumValue,
                           Description = GetDescription(enumValue)
                       }).ToArray();
        }

        private string GetDescription(object enumValue)
        {
            var descriptionAttribute = EnumType
                .GetField(enumValue.ToString())
                .GetCustomAttributes(typeof (DescriptionAttribute), false)
                .FirstOrDefault() as DescriptionAttribute;


            return descriptionAttribute != null
                ? descriptionAttribute.Description
                : enumValue.ToString();
        }

        #region Nested type: EnumerationMember
        public class EnumerationMember
        {
            public string Description { get; set; }
            public object Value { get; set; }
        }
        #endregion
    }
}

Disclaimer: I have no affiliation with DevExpress. Telerik is also a great library.

I would suggest converting them to Strings.

StringBuilder concatenated = new StringBuilder();
concatenated.append(a);
concatenated.append(b);
/// etc...
concatenated.append(e);

Then converting back to an Integer:

Integer.valueOf(concatenated.toString());

With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

You can use like this:

public static String executeHttpPost1(String url,
            HashMap<String, String> postParameters) throws UnsupportedEncodingException {
        // TODO Auto-generated method stub

        HttpClient client = getNewHttpClient();

        try{
        request = new HttpPost(url);

        }
        catch(Exception e){
            e.printStackTrace();
        }


        if(postParameters!=null && postParameters.isEmpty()==false){

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(postParameters.size());
            String k, v;
            Iterator<String> itKeys = postParameters.keySet().iterator();
            while (itKeys.hasNext()) 
            {
                k = itKeys.next();
                v = postParameters.get(k);
                nameValuePairs.add(new BasicNameValuePair(k, v));
            }     

            UrlEncodedFormEntity urlEntity  = new  UrlEncodedFormEntity(nameValuePairs);
            request.setEntity(urlEntity);

        }
        try {


            Response = client.execute(request,localContext);
            HttpEntity entity = Response.getEntity();
            int statusCode = Response.getStatusLine().getStatusCode();
            Log.i(TAG, ""+statusCode);


            Log.i(TAG, "------------------------------------------------");





                try{
                    InputStream in = (InputStream) entity.getContent(); 
                    //Header contentEncoding = Response.getFirstHeader("Content-Encoding");
                    /*if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
                        in = new GZIPInputStream(in);
                    }*/
                    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
                    StringBuilder str = new StringBuilder();
                    String line = null;
                    while((line = reader.readLine()) != null){
                        str.append(line + "\n");
                    }
                    in.close();
                    response = str.toString();
                    Log.i(TAG, "response"+response);
                }
                catch(IllegalStateException exc){

                    exc.printStackTrace();
                }


        } catch(Exception e){

            Log.e("log_tag", "Error in http connection "+response);         

        }
        finally {

        }

        return response;
    }

I quickly found out there's someone already made a helper: slack-cleaner for this.

And for me it's just:

slack-cleaner --token=<TOKEN> --message --channel jenkins --user "*" --perform

Since you now specified you want to add to it, what you want isn't a simple IEnumerable<T> but at least an ICollection<T>. I recommend simply using a List<T> like this:

List<object> myList=new List<object>();
myList.Add(1);
myList.Add(2);
myList.Add(3);

You can use myList everywhere an IEnumerable<object> is expected, since List<object> implements IEnumerable<object>.

(old answer before clarification)

You can't create an instance of IEnumerable<T> since it's a normal interface(It's sometimes possible to specify a default implementation, but that's usually used only with COM).

So what you really want is instantiate a class that implements the interface IEnumerable<T>. The behavior varies depending on which class you choose.

For an empty sequence use:

IEnumerable<object> e0=Enumerable.Empty<object>();

For an non empty enumerable you can use some collection that implements IEnumerable<T>. Common choices are the array T[], List<T> or if you want immutability ReadOnlyCollection<T>.

IEnumerable<object> e1=new object[]{1,2,3};
IEnumerable<object> e2=new List<object>(){1,2,3};
IEnumerable<object> e3=new ReadOnlyCollection(new object[]{1,2,3});

Another common way to implement IEnumerable<T> is the iterator feature introduced in C# 3:

IEnumerable<object> MyIterator()
{
  yield return 1;
  yield return 2;
  yield return 3;
}

IEnumerable<object> e4=MyIterator();

Faced the same Issue. I had an assosciation between 2 beans. In bean A I had defined the variable type as Integer and in bean B I had defined the same variable as Long. I changed both of them to Integer. This solved my issue.

I prefer readability first which most often does not use the setup method. I make an exception when a basic setup operation takes a long time and is repeated within each test.
At that point I move that functionality into a setup method using the @BeforeClass annotation (optimize later).

Example of optimization using the @BeforeClass setup method: I use dbunit for some database functional tests. The setup method is responsible for putting the database in a known state (very slow... 30 seconds - 2 minutes depending on amount of data). I load this data in the setup method annotated with @BeforeClass and then run 10-20 tests against the same set of data as opposed to re-loading/initializing the database inside each test.

Using Junit 3.8 (extending TestCase as shown in your example) requires writing a little more code than just adding an annotation, but the "run once before class setup" is still possible.

As noone has added it, it should be noted that going forward from Python 2.6+ the recommended way to do string formating is with format, to get ready for Python 3+.

print ["{0:0.2f}".format(i) for i in a]

The new string formating syntax is not hard to use, and yet is quite powerfull.

I though that may be pprint could have something, but I haven't found anything.

Try Jochen Kalmbach's Memory Leak Detector on Code Project. The URL to the latest version was somewhere in the comments when I last checked.

This is not possible. Linux permissions and windows permissions do not translate. They are machine specific. It would be a security hole to allow permissions to be set on files before they even arrive on the target system.

I vote for:

await Promise.all([someCall(), anotherCall()]);

Be aware of the moment you call functions, it may cause unexpected result:

// Supposing anotherCall() will trigger a request to create a new User

if (callFirst) {
  await someCall();
} else {
  await Promise.all([someCall(), anotherCall()]); // --> create new User here
}

But following always triggers request to create new User

// Supposing anotherCall() will trigger a request to create a new User

const someResult = someCall();
const anotherResult = anotherCall(); // ->> This always creates new User

if (callFirst) {
  await someCall();
} else {
  const finalResult = [await someResult, await anotherResult]
}

At least with Active Directory, I have been able to search by DistinguishedName by doing an LDAP query in this format (assuming that such a record exists with this distinguishedName):

"(distinguishedName=CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com)"

You could also just use jQuery to remove the contents of the div that contains your svg.

$("#container_div_id").html("");

I would choose Sequelize because of it's excellent documentation. It's just a honest opinion (I never really used MySQL with Node that much).

I found out setting the gesture to disabled only doesn't always work. It does work, but for me it only did after I once used the backgesture. Second time it wouldn't trigger the backgesture.

Fix for me was to delegate the gesture and implement the shouldbegin method to return NO:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    // Disable iOS 7 back gesture
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    // Enable iOS 7 back gesture
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
        self.navigationController.interactivePopGestureRecognizer.delegate = nil;
    }
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    return NO;
}

For users of GitHub, this worked for me:

1. In any branch protection rules where you wish to make the change, make sure Allow force pushes is enabled
2. git reset --hard <full_hash_of_commit_to_reset_to>
3. git push --force

This will "correct" the branch history on your local machine and the GitHub server, but anyone who has sync'ed this branch with the server since the bad commit will have the history on their local machine. If they have permission to push to the branch directly then these commits will show right back up when they sync.

All everyone else needs to do is the git reset command from above to "correct" the branch on their local machine. Of course they would need to be wary of any local commits made to this branch after the target hash. Cherry pick/backup and reapply those as necessary, but if you are in a protected branch then the number of people who can commit directly to it is likely limited.

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

As you can see in the Java Source of the java.lang.String class:

/**
 * Allocates a new <code>String</code> that contains characters from
 * a subarray of the character array argument. The <code>offset</code>
 * argument is the index of the first character of the subarray and
 * the <code>count</code> argument specifies the length of the
 * subarray. The contents of the subarray are copied; subsequent
 * modification of the character array does not affect the newly
 * created string.
 *
 * @param      value    array that is the source of characters.
 * @param      offset   the initial offset.
 * @param      count    the length.
 * @exception  IndexOutOfBoundsException  if the <code>offset</code>
 *               and <code>count</code> arguments index characters outside
 *               the bounds of the <code>value</code> array.
 */
public String(char value[], int offset, int count) {
    if (offset < 0) {
        throw new StringIndexOutOfBoundsException(offset);
    }
    if (count < 0) {
        throw new StringIndexOutOfBoundsException(count);
    }
    // Note: offset or count might be near -1>>>1.
    if (offset > value.length - count) {
        throw new StringIndexOutOfBoundsException(offset + count);
    }

    this.value = new char[count];
    this.count = count;
    System.arraycopy(value, offset, this.value, 0, count);
}

Parameter references are surrounded by <code></code> tags, which means that the Javadoc syntax does not provide any way to do such a thing. (I think String.class is a good example of javadoc usage).

I am sorry everyone that this is the solution the true one where you dont have to actually set the padding.

http://jsfiddle.net/techsin/TyXRY/1/

What i have done...

• Applied two gradients on background with both having one start and end color. Instead of using solid color. Reason being that you can't have two solid colors for one background.
• Then applied different background-clip property to each.
• thus making one color extend to content box and other to border, revealing the padding.

Clever if i say so to myself.

div {
    padding: 35px;
    background-image:
      linear-gradient(to bottom,
        rgba(240, 255, 40, 1) 0%,
        rgba(240, 255, 40, 1) 100%),
      linear-gradient(to bottom,
        rgba(240, 40, 40, 1) 0%,
        rgba(240, 40, 40, 1) 100%);
    background-clip: content-box, padding-box;
}

All answers provided thus far result in potentially dangerous behavior as it is quite possible you select a dummy value that is actually part of the dataset. This is increasingly likely as you create groups with many attributes. Simply put, the approach doesn't always generalize well.

A less hacky solve is to use pd.drop_duplicates() to create a unique index of value combinations each with their own ID, and then group on that id. It is more verbose but does get the job done:

def safe_groupby(df, group_cols, agg_dict):
    # set name of group col to unique value
    group_id = 'group_id'
    while group_id in df.columns:
        group_id += 'x'
    # get final order of columns
    agg_col_order = (group_cols + list(agg_dict.keys()))
    # create unique index of grouped values
    group_idx = df[group_cols].drop_duplicates()
    group_idx[group_id] = np.arange(group_idx.shape[0])
    # merge unique index on dataframe
    df = df.merge(group_idx, on=group_cols)
    # group dataframe on group id and aggregate values
    df_agg = df.groupby(group_id, as_index=True)\
               .agg(agg_dict)
    # merge grouped value index to results of aggregation
    df_agg = group_idx.set_index(group_id).join(df_agg)
    # rename index
    df_agg.index.name = None
    # return reordered columns
    return df_agg[agg_col_order]

Note that you can now simply do the following:

data_block = [np.tile([None, 'A'], 3),
              np.repeat(['B', 'C'], 3),
              [1] * (2 * 3)]

col_names = ['col_a', 'col_b', 'value']

test_df = pd.DataFrame(data_block, index=col_names).T

grouped_df = safe_groupby(test_df, ['col_a', 'col_b'],
                          OrderedDict([('value', 'sum')]))

This will return the successful result without having to worry about overwriting real data that is mistaken as a dummy value.

Check this thread out: read and write image file.

Also, have a look at this other question at Stackoverflow.

We used the random_state parameter for reproducibility of the initial shuffling of training datasets after each epoch.

Changing an image is easy, but how do you change it back to the original size after it has been changed? You may try this to change all images in a document back to the original size:

var i,L=document.images.length;
for(i=0;i<L;++i){
 document.images[i].style.height = 'auto'; //setting CSS value
 document.images[i].style.width = 'auto'; //setting CSS value
// document.images[i].height = ''; (don't need this, would be setting img.attribute)
// document.images[i].width = ''; (don't need this, would be setting img.attribute)
}

To increase the font size of netbeans 7.3.1 and 7.3 , you go from menu Tools>>Options>>"Fonts & Colors" (is an inner menu in the dialog window of Options)

At the "Syntax" tab ,every entry in the "Category:" list-box ,you will notice that the font has the value "Inherited". If you find in the "Category" list-box the entry with the name "Default" and change the font value of that, you will affect the font size of your editor, because everything is inherited from "Default" entry .

Another method is to increase temporary the font of the editor by a combination of keys. To find what are the keys go to the "Options" dialog window by Tools>> Options and then choose the "Keymap" menu entry and then in the "Search" textbox type "zoom text" and it will show you what combinations of keys for zooming in /out.

for example mine is the combination of "alt" key + mouse wheel up/down

If the IDE you use(in case you use one) might have been getting in the way as well. That's what happened to me when using QtCreator.

I had this issue when I upgraded to v3.0.0.preview4, so a downgrade to a stable version fixed this.

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

UINavigationItem* item = [[UINavigationItem alloc] initWithTitle:@"title text"];
...
[bar pushNavigationItem:item animated:YES];
[item release];

This code worked.

From MSDN:

C#, through the .NET Framework common language runtime (CLR), automatically releases the memory used to store objects that are no longer required. The release of memory is non-deterministic; memory is released whenever the CLR decides to perform garbage collection. However, it is usually best to release limited resources such as file handles and network connections as quickly as possible.

The using statement allows the programmer to specify when objects that use resources should release them. The object provided to the using statement must implement the IDisposable interface. This interface provides the Dispose method, which should release the object's resources.

In other words, the using statement tells .NET to release the object specified in the using block once it is no longer needed.

Very old question, but just had to build this for an app today and found the settings shown in other answers do not result in a clean image (possibly as new options were added in later .Net versions).

Assuming you want the text in the centre of the bitmap, you can do this:

// Load the original image
Bitmap bmp = new Bitmap("filename.bmp");

// Create a rectangle for the entire bitmap
RectangleF rectf = new RectangleF(0, 0, bmp.Width, bmp.Height);

// Create graphic object that will draw onto the bitmap
Graphics g = Graphics.FromImage(bmp);

// ------------------------------------------
// Ensure the best possible quality rendering
// ------------------------------------------
// The smoothing mode specifies whether lines, curves, and the edges of filled areas use smoothing (also called antialiasing). 
// One exception is that path gradient brushes do not obey the smoothing mode. 
// Areas filled using a PathGradientBrush are rendered the same way (aliased) regardless of the SmoothingMode property.
g.SmoothingMode = SmoothingMode.AntiAlias;

// The interpolation mode determines how intermediate values between two endpoints are calculated.
g.InterpolationMode = InterpolationMode.HighQualityBicubic;

// Use this property to specify either higher quality, slower rendering, or lower quality, faster rendering of the contents of this Graphics object.
g.PixelOffsetMode = PixelOffsetMode.HighQuality;

// This one is important
g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;

// Create string formatting options (used for alignment)
StringFormat format = new StringFormat()
{
    Alignment = StringAlignment.Center,
    LineAlignment = StringAlignment.Center
};

// Draw the text onto the image
g.DrawString("yourText", new Font("Tahoma",8), Brushes.Black, rectf, format);

// Flush all graphics changes to the bitmap
g.Flush();

// Now save or use the bitmap
image.Image = bmp;

If you have epoch in milliseconds a possible solution is convert to seconds:

I solved this way

class MyOnClickListener implements View.OnClickListener {
        @Override
        public void onClick(View v) {

            int itemPosition = mRecyclerView.getChildAdapterPosition(v);

            myResult = results.get(itemPosition);


        }
    }

And in the adapter

@Override
        public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                       int viewType) {            
            View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_wifi, parent, false);
            v.setOnClickListener(new MyOnClickListener());
            ViewHolder vh = new ViewHolder(v);
            return vh;
        }

There is another case where the two possibilities differ, on top of those already mentioned: if you need to call a non-public constructor (protected or private), make_shared might not be able to access it, while the variant with the new works fine.

class A
{
public:

    A(): val(0){}

    std::shared_ptr<A> createNext(){ return std::make_shared<A>(val+1); }
    // Invalid because make_shared needs to call A(int) **internally**

    std::shared_ptr<A> createNext(){ return std::shared_ptr<A>(new A(val+1)); }
    // Works fine because A(int) is called explicitly

private:

    int val;

    A(int v): val(v){}
};

If you want to use the iframe's scrollbar and not the parent's use this:

document.body.style.overflow = 'hidden';

If you want to use the parent's scrollbar and not the iframe's then you need to use:

document.getElementById('your_iframes_id').scrolling = 'no';

or set the scrolling="no" attribute in your iframe's tag: <iframe src="some_url" scrolling="no">.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

You need to add the hibernate-entitymanager-x.jar in the classpath.

In Hibernate 4.x, if the jar is present, then no need to add the org.hibernate.ejb.HibernatePersistence in persistence.xml file.

I recommend you this repository, https://github.com/DonJayamanne/gitHistoryVSCode

Git History

It does exactly what you need and has these features:

• View the details of a commit, such as author name, email, date, committer name, email, date and comments.
• View a previous copy of the file or compare it against the local workspace version or a previous version.
• View the changes to the active line in the editor (Git Blame).
• Configure the information displayed in the list
• Use keyboard shortcuts to view history of a file or line
• View the Git log (along with details of a commit, such as author name, email, comments and file changes).

You won't gain anything by checking that the key exists. This is the code of HashMap:

@Override
public boolean containsKey(Object key) {
    Entry<K, V> m = getEntry(key);
    return m != null;
}

@Override
public V get(Object key) {
    Entry<K, V> m = getEntry(key);
    if (m != null) {
        return m.value;
    }
    return null;
}

Just check if the return value for get() is different from null.

This is the HashMap source code.

Since the question delves into if DELETE "should" return 200 vs 204 it is worth considering that some people recommend returning an entity with links so the preference is for 200.

"Instead of returning 204 (No Content), the API should be helpful and suggest places to go. In this example I think one obvious link to provide is to" 'somewhere.com/container/' (minus 'resource') "- the container from which the client just deleted a resource. Perhaps the client wishes to delete more resources, so that would be a helpful link."

http://blog.ploeh.dk/2013/04/30/rest-lesson-learned-avoid-204-responses/

If a client encounters a 204 response, it can either give up, go to the entry point of the API, or go back to the previous resource it visited. Neither option is particularly good.

Personally I would not say 204 is wrong (neither does the author; he says "annoying") because good caching at the client side has many benefits. Best is to be consistent either way.

You just need to add 'table-layout: fixed;'

.table {
   display: table;
   height: 100px;
   width: 100%;
   table-layout: fixed;
}

http://www.w3schools.com/cssref/pr_tab_table-layout.asp

You need to provide a default value:

new_field = models.CharField(max_length=140, default='SOME STRING')

This is probably a noob answer, but: I use TortoiseGit for windows and it has a nice feature called REVERT. So what you do to revert your local nonstaged nonpushed changes is:

1. bring up a context menu for the needed folder and select revert, it shows a revert popup where you can select changed files to revert/recover.
2. If you also want to delete added files(that are not in git yet) click commit (from same context menu) it brings up the Commit popup and shows you the added files, then right click each of them and choose delete. But dont press Commit btn in this popup, as you dont wanna commit, but only see added files and delete them from here.

Using Windows Command Prompt:

rmdir /s /q folder

Using Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

Adding some information here, as it took me awhile to find the hadoop jobtracker web-dashboard in HDInsight (Azure's Hadoop), and a colleague finally showed me where it was. There is a shortcut on the head node called "Hadoop Yarn Status" which is just a link to a local http page (http://headnodehost:9014/cluster in my case). When opened the dashboard looked like this:

In that dashboard you can find your failed application, and then after clicking into it you can look at the logs of the individual map and reduce jobs.

In my case it seemed to still be running out of memory in the reducers, even though I had cranked the memory in the configuration already. For some reason it was not surfacing the "java outofmemory" errors I got earlier though.

Here you can do it by using HttpRequest or HttpSession. And think your problem is within the JSP.

If you are going to use the inside servlet do following,

Object obj = new Object();
session.setAttribute("object", obj);

or

HttpSession session = request.getSession();
Object obj = new Object();
session.setAttribute("object", obj);

and after setting your attribute by using request or session, use following to access it in the JSP,

<%= request.getAttribute("object")%>

or

<%= session.getAttribute("object")%>

So seems your problem is in the JSP.

If you want use scriptlets it should be as follows,

<%
Object obj = request.getSession().getAttribute("object");
out.print(obj);
%>

Or can use expressions as follows,

<%= session.getAttribute("object")%>

or can use EL as follows, ${object} or ${sessionScope.object}

In addition to the existing answers, Overridden functions are in different scopes; whereas overloaded functions are in same scope.

Try this

RelativeLayout relative = (RelativeLayout) findViewById(R.id.widget29);
relative.setBackgroundResource(0);

Check the setBackground functions in the RelativeLayout documentation

For me it was a two part. First:

pip uninstall numpy

Then @Oli Blum answer (thank you):

conda install -c conda-forge numpy

That did the trick for me

You can use array slicing:

Entry.objects.all()[:1].get()

Which can be used with .filter():

Entry.objects.filter()[:1].get()

You wouldn't want to first turn it into a list because that would force a full database call of all the records. Just do the above and it will only pull the first. You could even use .order_by() to ensure you get the first you want.

Be sure to add the .get() or else you will get a QuerySet back and not an object.

See this article for tips on how to help performance issues. This includes both performance issues related to starting up, under the "cold start" section. Most of this will matter no matter what type of server you are using, locally or in production.

https://blogs.msdn.microsoft.com/b/mcsuksoldev/2011/01/19/common-performance-issues-on-asp-net-web-sites/

If the application deserializes anything from XML (and that includes web services…) make sure SGEN is run against all binaries involved in deseriaization and place the resulting DLLs in the Global Assembly Cache (GAC). This precompiles all the serialization objects used by the assemblies SGEN was run against and caches them in the resulting DLL. This can give huge time savings on the first deserialization (loading) of config files from disk and initial calls to web services. http://msdn.microsoft.com/en-us/library/bk3w6240(VS.80).aspx

If any IIS servers do not have outgoing access to the internet, turn off Certificate Revocation List (CRL) checking for Authenticode binaries by adding generatePublisherEvidence=”false” into machine.config. Otherwise every worker processes can hang for over 20 seconds during start-up while it times out trying to connect to the internet to obtain a CRL list. http://blogs.msdn.com/amolravande/archive/2008/07/20/startup-performance-disable-the-generatepublisherevidence-property.aspx

http://msdn.microsoft.com/en-us/library/bb629393.aspx

Consider using NGEN on all assemblies. However without careful use this doesn’t give much of a performance gain. This is because the base load addresses of all the binaries that are loaded by each process must be carefully set at build time to not overlap. If the binaries have to be rebased when they are loaded because of address clashes, almost all the performance gains of using NGEN will be lost. http://msdn.microsoft.com/en-us/magazine/cc163610.aspx

Besides raise Exception("message") and raise Python 3 introduced a new form, raise Exception("message") from e. It's called exception chaining, it allows you to preserve the original exception (the root cause) with its traceback.

It's very similar to inner exceptions from C#.

For line chart, I use the following codes.

First create custom style

.boxx{
    position: relative;
    width: 20px;
    height: 20px;
    border-radius: 3px;
}

Then add this on your line options

var lineOptions = {
            legendTemplate : '<table>'
                            +'<% for (var i=0; i<datasets.length; i++) { %>'
                            +'<tr><td><div class=\"boxx\" style=\"background-color:<%=datasets[i].fillColor %>\"></div></td>'
                            +'<% if (datasets[i].label) { %><td><%= datasets[i].label %></td><% } %></tr><tr height="5"></tr>'
                            +'<% } %>'
                            +'</table>',
            multiTooltipTemplate: "<%= datasetLabel %> - <%= value %>"

var ctx = document.getElementById("lineChart").getContext("2d");
var myNewChart = new Chart(ctx).Line(lineData, lineOptions);
document.getElementById('legendDiv').innerHTML = myNewChart.generateLegend();

Don't forget to add

<div id="legendDiv"></div>

on your html where do you want to place your legend. That's it!

db2 connect to MY_INSTACE_DB with myuser -- connect to db2    
db2 "select TABNAME from syscat.tables where tabschema = 'mySchema' with ur"
db2 terminate -- end connection

This still isn't automatic, as I wish there was an option for - and there should be some checking to make sure that this can only happen for fast-forward updates (which is why manually doing a pull is far safer!!), but caveats aside you can:

git fetch origin
git update-ref refs/heads/other-branch origin/other-branch

to update the position of your local branch without having to check it out.

Note: you will be losing your current branch position and moving it to where the origin's branch is, which means that if you need to merge you will lose data!

$>  mysql -u root -p -e 'Select user from mysql.user' > allUsersOnDatabase.txt

Executing this command on linux prompt will first ask for the password of mysql root user, on providing correct password it will print all the database users to the text file.

Using two datasources you need their own transaction managers.

@Configuration
public class MySqlDBConfig {
    @Bean
    @Primary
    @ConfigurationProperties(prefix="datasource.test.mysql")
    public DataSource mysqlDataSource(){
         return DataSourceBuilder
                 .create()
                 .build();
    }

    @Bean("mysqlTx")
    public DataSourceTransactionManager mysqlTx() {
        return new DataSourceTransactionManager(mysqlDataSource());
    }

    // same for another DS
}

And then use it accordingly within @Transaction

@Transactional("mysqlTx")
@Repository
public interface UserMysqlDao extends CrudRepository<UserMysql, Integer>{
    public UserMysql findByName(String name);
}

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

While developing the ios app i too face similar kind of issue. Simple Restart of the xcode works for me. Hope this will help some one.

If you have a std::wstring object, you can call c_str() on it to get a wchar_t*:

std::wstring name( L"Steve Nash" );
const wchar_t* szName = name.c_str();

Since you are operating on a narrow string, however, you would first need to widen it. There are various options here; one is to use Windows' built-in MultiByteToWideChar routine. That will give you an LPWSTR, which is equivalent to wchar_t*.

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

The most straightforward way:

long millisInDay = 60 * 60 * 24 * 1000;
long currentTime = new Date().getTime();
long dateOnly = (currentTime / millisInDay) * millisInDay;
Date clearDate = new Date(dateOnly);

h2.text-left{
  position:relative;
  top:50%;
  transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
}

Explanation:

The top:50% style essentially pushes the header element down 50% from the top of the parent element. The translateY stylings also act in a similar manner by moving then element down 50% from the top.

Please note that this works well for headers with 1 (maybe 2) lines of text as this simply moves the top of the header element down 50% and then the rest of the content fills in below that, which means that with multiple lines of text it would appear to be slightly below vertically aligned.

A possible fix for multiple lines would be to use a percentage slightly less than 50%.

I had the same problem 2 years ago and I solved it in the following way:

1) I build my projects with makefiles, not managed by eclipse 2) I use a SAMBA connection to edit the files inside Eclipse 3) Building the project: Eclipse calles a "local" make with a makefile which opens a SSH connection to the Linux Host. On the SSH command line you can give parameters which are executed on the Linux host. I use for that parameter a makeit.sh shell script which call the "real" make on the linux host. The different targets for building you can give also by parameters from the local makefile --> makeit.sh --> makefile on linux host.

exit is a helper for the interactive shell - sys.exit is intended for use in programs.

The site module (which is imported automatically during startup, except if the -S command-line option is given) adds several constants to the built-in namespace (e.g. exit). They are useful for the interactive interpreter shell and should not be used in programs.

Technically, they do mostly the same: raising SystemExit. sys.exit does so in sysmodule.c:

static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
    PyObject *exit_code = 0;
    if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
        return NULL;
    /* Raise SystemExit so callers may catch it or clean up. */
    PyErr_SetObject(PyExc_SystemExit, exit_code);
   return NULL;
}

While exit is defined in site.py and _sitebuiltins.py, respectively.

class Quitter(object):
    def __init__(self, name):
        self.name = name
    def __repr__(self):
        return 'Use %s() or %s to exit' % (self.name, eof)
    def __call__(self, code=None):
        # Shells like IDLE catch the SystemExit, but listen when their
        # stdin wrapper is closed.
        try:
            sys.stdin.close()
        except:
            pass
        raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')

Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()).

If your PHP version is 5, try installing cURL by typing the following command in the terminal:

sudo apt-get install php5-curl

$request->fullUrl() will also work if you are injecting Illumitate\Http\Request.

Just had the same question recently and successfully used https://npmjs.org/package/tea-properties which also set nested object/arrays :

get:

var o = {
  prop: {
    arr: [
      {foo: 'bar'}
    ]
  }
};

var properties = require('tea-properties');
var value = properties.get(o, 'prop.arr[0].foo');

assert(value, 'bar'); // true

set:

var o = {};

var properties = require('tea-properties');
properties.set(o, 'prop.arr[0].foo', 'bar');

assert(o.prop.arr[0].foo, 'bar'); // true

In case you want a quicker (but still very clean) way of achieving it for a personal purpose (for instance if you want to build a specific project having some strong requirements concerning the version of the compiler), just follow the following steps:

• type echo $PATH and look for a personal directory having a very high priority (in my case, I have ~/.local/bin);
• add the symbolic links in this directory:

For instance:

ln -s /usr/bin/gcc-WHATEVER ~/.local/bin/gcc
ln -s /usr/bin/g++-WHATEVER ~/.local/bin/g++

Of course, this will work for a single user (it isn't a system wide solution), but on the other hand I don't like to change too many things in my installation.

two ways:

x = [0] * 10
x = [0 for i in xrange(10)]

Edit: replaced range by xrange to avoid creating another list.

Also: as many others have noted including Pi and Ben James, this creates a list, not a Python array. While a list is in many cases sufficient and easy enough, for performance critical uses (e.g. when duplicated in thousands of objects) you could look into python arrays. Look up the array module, as explained in the other answers in this thread.

The destructor of A will run when its lifetime is over. If you want its memory to be freed and the destructor run, you have to delete it if it was allocated on the heap. If it was allocated on the stack this happens automatically (i.e. when it goes out of scope; see RAII). If it is a member of a class (not a pointer, but a full member), then this will happen when the containing object is destroyed.

class A
{
    char *someHeapMemory;
public:
    A() : someHeapMemory(new char[1000]) {}
    ~A() { delete[] someHeapMemory; }
};

class B
{
    A* APtr;
public:
    B() : APtr(new A()) {}
    ~B() { delete APtr; }
};

class C
{
    A Amember;
public:
    C() : Amember() {}
    ~C() {} // A is freed / destructed automatically.
};

int main()
{
    B* BPtr = new B();
    delete BPtr; // Calls ~B() which calls ~A() 
    C *CPtr = new C();
    delete CPtr;
    B b;
    C c;
} // b and c are freed/destructed automatically

In the above example, every delete and delete[] is needed. And no delete is needed (or indeed able to be used) where I did not use it.

auto_ptr, unique_ptr and shared_ptr etc... are great for making this lifetime management much easier:

class A
{
    shared_array<char> someHeapMemory;
public:
    A() : someHeapMemory(new char[1000]) {}
    ~A() { } // someHeapMemory is delete[]d automatically
};

class B
{
    shared_ptr<A> APtr;
public:
    B() : APtr(new A()) {}
    ~B() {  } // APtr is deleted automatically
};

int main()
{
    shared_ptr<B> BPtr = new B();
} // BPtr is deleted automatically

Your repository is broken. But you can probably fix it AND keep your edits:

1. Back up first: cp your_repository your_repositry_bak
2. Clone the broken repository (still works): git clone your_repository your_repository_clone
3. Replace the broken .git folder with the one from the clone: rm -rf your_repository/.git && cp your_repository_clone/.git your_repository/ -r
4. Delete clone & backup (if everything is fine): rm -r your_repository_*

You can also try using runuser (as root) to run a command as a different user

*/1 * * * * runuser php5 \
            --command="/var/www/web/includes/crontab/queue_process.php \
                       >> /var/www/web/includes/crontab/queue.log 2>&1"

See also: man runuser

In regards to your code, see @Coulton. You'll need to use JavaScript.

Checkout either FitText (it does work in IE, they just ballsed their site somehow) or BigText.

FitText will allow you to scale some text in relation to the container it is in, while BigText is more about resizing different sections of text to be the same width within the container.

BigText will set your string to exactly the width of the container, whereas FitText is less pixel perfect. It starts by setting the font-size at 1/10th of the container element's width. It doesn't work very well with all fonts by default, but it has a setting which allows you to decrease or increase the 'power' of the re-size. It also allows you to set a min and max font-size. It will take a bit of fiddling to get working the first time, but does work great.

http://marabeas.io <- playing with it currently here. As far as I understand, BigText wouldn't work in my context at all.

For those of you using Angularjs, here's an Angular version of FitText I've made.

Here's a LESS mixin you can use to make @humanityANDpeace's solution a little more pretty:

@mqIterations: 19;
.fontResize(@i) when (@i > 0) {
    @media all and (min-width: 100px * @i) { body { font-size:0.2em * @i; } }
    .fontResize((@i - 1));
}
.fontResize(@mqIterations);

And an SCSS version thanks to @NIXin!

$mqIterations: 19;
@mixin fontResize($iterations) { 
    $i: 1; 
    @while $i <= $iterations { 
        @media all and (min-width: 100px * $i) { body { font-size:0.2em * $i; } } 
        $i: $i + 1; 
    }
} 
@include fontResize($mqIterations);

The problem is that the small figure region 2 created by your layout() call is not sufficiently large enough to contain just the default margins, let alone a plot.

More generally, you get this error if the size of the plotting region on the device is not large enough to actually do any plotting. For the OP's case the issue was having too small a plotting device to contain all the subplots and their margins and leave a large enough plotting region to draw in.

RStudio users can encounter this error if the Plot tab is too small to leave enough room to contain the margins, plotting region etc. This is because the physical size of that pane is the size of the graphics device. These are not independent issues; the plot pane in RStudio is just another plotting device, like png(), pdf(), windows(), and X11().

Solutions include:

1. reducing the size of the margins; this might help especially if you are trying, as in the case of the OP, to draw several plots on the same device.

2. increasing the physical dimensions of the device, either in the call to the device (e.g. png(), pdf(), etc) or by resizing the window / pane containing the device

3. reducing the size of text on the plot as that can control the size of margins etc.

Reduce the size of the margins

Before the line causing the problem try:

par(mar = rep(2, 4))

then plot the second image

image(as.matrix(leg),col=cx,axes=T)

You'll need to play around with the size of the margins on the par() call I show to get this right.

Increase the size of the device

You may also need to increase the size of the actual device onto which you are plotting.

A final tip, save the par() defaults before changing them, so change your existing par() call to:

op <- par(oma=c(5,7,1,1))

then at the end of plotting do

par(op)

None of the above worked for me, the only one working was

insert into tableName

The nullif is used since it is not possible to pass null in the select statement otherwise.

The basic questions that differentiate implementations of "CopyStream" are:

• size of the reading buffer
• size of the writes
• Can we use more than one thread (writing while we are reading).

The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.

In System.Diagnostics,

Debug.Write()
Debug.WriteLine()

etc. will print to the Output window in VS.

I would like to give you a background on Universal CRT this would help you in understanding as to why the system should be updated before installing vc_redist.x64.exe. A large portion of the C-runtime moved into the OS in Windows 10 (ucrtbase.dll) and is serviced just like any other OS DLL (e.g. kernel32.dll). It is no longer serviced by Visual Studio directly. MSU packages are the file type for Windows Updates.

In order to get the Windows 10 Universal CRT to earlier OSes, Windows Update packages were created to bring this OS component downlevel. KB2999226 brings the Windows 10 RTM Universal CRT to downlevel platforms (Windows Vista through Windows 8.1). KB3118401 brings Windows 10 November Update to the Universal CRT to downlevel platforms.

Windows XP (latest SP) is an exception here. Windows Servicing does not provide downlevel packages for that OS, so Visual Studio (Visual C++) provides a mechanism to install the UCRT into System32 via the VCRedist and MSMs.

1.The Windows Universal Runtime is included in the VC Redist exe package as it has dependency on the Windows Universal Runtime (KB2999226). Windows 10 is the only OS that ships the UCRT in-box. All prior OSes obtain the UCRT via Windows Update only. This applies to all Vista->8.1 and associated Server SKUs.

For Windows 7, 8, and 8.1 the Windows Universal Runtime must be installed via KB2999226. However it has a prerequisite update KB2919355 which contains updates that facilitate installing the KB2999226 package.

2. Why does KB2999226 not always install when the runtime is installed from the redistributable? What could prevent KB2999226 from installing as part of the runtime? The UCRT MSU included in the VCRedist is installed by making a call into the Windows Update service and the KB can fail to install based upon Windows Update service activity/state: 1) If the machine has not updated to the required servicing baseline, the UCRT MSU will be viewed as being “Not Applicable”. Ensure KB2919355 is installed. Also, there were known issues with KB2919355 so before this the following hotfix should be installed. KB2939087 KB2975061 2) If the Windows Update service is installing other updates when the VCRedist installs, you can either see long delays or errors indicating the machine is busy. a. This one can be resolved by waiting and trying again later (which may be why installing via Windows Update UI at a later time succeeds). 3) If the Windows Update service is in a non-ready state, you can see errors reflecting that. a. We recently investigated a failure with an error code indicating the WUSA service was shutting down.

3. To identify if the prerequisite KB2919355 is installed there are 2 options: Registry key: 64bit hive HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14 CurrentState = 112 32bit hive HKLM\SOFTWARE[WOW6432Node]Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_for_KB2919355~31bf3856ad364e35~x86~~6.3.1.14 CurrentState = 112

Or check the file version of: C:\Windows\SysWOW64\wuaueng.dll C:\Windows\System32\wuaueng.dll 7.9.9600.17031 or later

This stems from the fact that on deletion, the iteration skips one element as it semms only to work on the index.

Workaround could be:

x = ["ok", "jj", "uy", "poooo", "fren"]
for item in x[:]: # make a copy of x
    if len(item) != 2:
        print "length of %s is: %s" %(item, len(item))
        x.remove(item)

You can use Application class(public class in android.application package),that is:

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created.

To use this class do:

public class App extends Application {

    private static Context mContext;

    public static Context getContext() {
        return mContext;
    }

    public static void setContext(Context mContext) {
        this.mContext = mContext;
    }

    ...

}

In your manifest:

<application
        android:icon="..."
        android:label="..."
        android:name="com.example.yourmainpackagename.App" >
                       class that extends Application ^^^

In Activity B:

public class B extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.sampleactivitylayout);

        App.setContext(this);
                  ...
        }
...
}

In class A:

Context c = App.getContext();

Note:

There is normally no need to subclass Application. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given a Context which internally uses Context.getApplicationContext() when first constructing the singleton.

You can use this keyword to access custom data, passed to $.ajax() function:

    $.ajax({
        // ... // --> put ajax configuration parameters here
        yourCustomData: {param1: 'any value', time: '1h24'},  // put your custom key/value pair here
        success: successHandler
    });

    function successHandler(data, textStatus, jqXHR) {
        alert(this.yourCustomData.param1);  // shows "any value"
        console.log(this.yourCustomData.time);
    }

To elaborate on this answer, in case you have multiple commits to move from, e.g. develop to new_branch:

git checkout develop # You're probably there already
git reflog # Find LAST_GOOD, FIRST_NEW, LAST_NEW hashes
git checkout new_branch
git cherry-pick FIRST_NEW^..LAST_NEW # ^.. includes FIRST_NEW
git reflog # Confirm that your commits are safely home in their new branch!
git checkout develop
git reset --hard LAST_GOOD # develop is now back where it started

This is what worked for me in the end.

var showMenu = function(el, menu) {
    //get the position of the placeholder element  
    var pos = $(el).offset();    
    var eWidth = $(el).outerWidth();
    var mWidth = $(menu).outerWidth();
    var left = (pos.left + eWidth - mWidth) + "px";
    var top = 3+pos.top + "px";
    //show the menu directly over the placeholder  
    $(menu).css( { 
        position: 'absolute',
        zIndex: 5000,
        left: left, 
        top: top
    } );

    $(menu).hide().fadeIn();
};

When you're using Data Type: int you can select the row which you want to get autoincremented and go to the column properties tag. There you can set the identity to 'yes'. The starting value for autoincrement can also be edited there. Hope I could help ;)

Since PHP 5.5, there is a separate php.ini file for CLI interface. If You use symfony console from command line, then this specific php.ini is used.

In Ubuntu 13.10 check file:

/etc/php5/cli/php.ini

It's as easy as:

DECLARE @rv FLOAT;
SELECT @rv = rand();

And this will put a random number between 0-99 into a table:

CREATE TABLE R
(
    Number int
)

DECLARE @rv FLOAT;
SELECT @rv = rand();

INSERT INTO dbo.R
(Number)
    values((@rv * 100));

SELECT * FROM R

For Decryption:

     def decrypt(my_key=KEY, my_iv=IV, encryptText=encrypttext):

        key = binascii.unhexlify(my_key)
        iv = binascii.unhexlify(my_iv)
        encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128)  # Initialize encryptor
        result = encryptor.decrypt(binascii.a2b_hex(encryptText))
        padder = PKCS7Padder()
        decryptText=padder.decode(result)  

           return {
          "plain": encryptText,
          "key": binascii.hexlify(key),
          "iv": binascii.hexlify(iv),
          "decryptedTest": decryptText
}

Python evaluates expressions from left to right. Notice that while evaluating an assignment, the right-hand side is evaluated before the left-hand side.

Python docs: Evaluation order

That means the following for the expression a,b = b,a :

• The right-hand side b,a is evaluated, that is to say, a tuple of two elements is created in the memory. The two elements are the objects designated by the identifiers b and a, that were existing before the instruction is encountered during the execution of the program.
• Just after the creation of this tuple, no assignment of this tuple object has still been made, but it doesn't matter, Python internally knows where it is.
• Then, the left-hand side is evaluated, that is to say, the tuple is assigned to the left-hand side.
• As the left-hand side is composed of two identifiers, the tuple is unpacked in order that the first identifier a be assigned to the first element of the tuple (which is the object that was formerly b before the swap because it had name b)
  and the second identifier b is assigned to the second element of the tuple (which is the object that was formerly a before the swap because its identifiers was a)

This mechanism has effectively swapped the objects assigned to the identifiers a and b

So, to answer your question: YES, it's the standard way to swap two identifiers on two objects.
By the way, the objects are not variables, they are objects.

Try this

public static void main(String[] args)
{

    String original = "ABCDEFGHIJKLMNOPQ";
    String tobeChecked = "GHi";

    System.out.println(containsString(original, tobeChecked, true));        
    System.out.println(containsString(original, tobeChecked, false));

}

public static boolean containsString(String original, String tobeChecked, boolean caseSensitive)
{
    if (caseSensitive)
    {
        return original.contains(tobeChecked);

    }
    else
    {
        return original.toLowerCase().contains(tobeChecked.toLowerCase());
    }

}

The only thing which worked for me is this

fetchData()
  .subscribe(
    (data) => {
       //Called when success
     },
    (error) => {
       //Called when error
    }
  ).add(() => {
       //Called when operation is complete (both success and error)
  });

The simplest way to get stage object in controller is:

1. Add an extra method in own created controller class like (it will be a setter method to set the stage in controller class),

   private Stage myStage;
   public void setStage(Stage stage) {
        myStage = stage;
   }
   

2. Get controller in start method and set stage

   FXMLLoader loader = new FXMLLoader(getClass().getResource("MyFXML.fxml"));
   OwnController controller = loader.getController();
   controller.setStage(this.stage);
   

3. Now you can access the stage in controller

Try this:

a = 1
b = 2
int_div  = a // b

For a solution in Swift please refer to this thread on SO.

Basically the solution in Swift would look like this:

#if DEBUG
    println("I'm running in DEBUG mode")
#else
    println("I'm running in a non-DEBUG mode")
#endif

Additionally you will need to set the DEBUG symbol in Swift Compiler - Custom Flags section for the Other Swift Flags key via a -D DEBUG entry. See the following screenshot for an example:

PHP does not support overloading for now. Hope this will be implemented in the other versions like other programming languages.

Checkout this library, This will allow you to use PHP Overloading in terms of closures. https://github.com/Sahil-Gulati/Overloading

I found that I can run this command:

notepad $((Split-Path $profile -Parent) + "\profile.ps1")

and it opens my default powershell profile (at least when using Terminal for Windows). I found that here.

Then add an alias. For example, here is my alias of jn for jupyter notebook (I hate typing out the cumbersome jupyter notebook every time):

Set-Alias -Name jn -Value C:\Users\words\Anaconda3\Scripts\jupyter-notebook.exe

In order to reset the value in angular 2 use:

this.rootNode.findNode("objectname").resetValue();

There's also recursive-blame. It can be installed with

npm install -g recursive-blame

Try using the key keyword with sorted().

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda x: x[1])

key should be a function that identifies how to retrieve the comparable element from your data structure. In your case, it is the second element of the tuple, so we access [1].

For optimization, see jamylak's response using itemgetter(1), which is essentially a faster version of lambda x: x[1].

Add the following inside the end of the try/catch to avoid the error that appears when the JSP engine flushes the response via getWriter()

out.clear(); // where out is a JspWriter
out = pageContext.pushBody();

As has been noted, this isn't best practice, but it avoids the errors in your logs.

Why not use .style of the DOM element? It's an object which contains members such as width and backgroundColor.

I take the below approach to remove the item in slice. This helps in readability for others. And also immutable.

func remove(items []string, item string) []string {
    newitems := []string{}

    for _, i := range items {
        if i != item {
            newitems = append(newitems, i)
        }
    }

    return newitems
}

curl_getinfo — Get information regarding a specific transfer

Check curl_getinfo

<?php
// Create a curl handle
$ch = curl_init('http://www.yahoo.com/');

// Execute
curl_exec($ch);

// Check if any error occurred
if(!curl_errno($ch))
{
 $info = curl_getinfo($ch);

 echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
}

// Close handle
curl_close($ch);

For something with 2 parameters, you could use BiFunction. If you need more, you can define your own function interface, like so:

@FunctionalInterface
public interface FourParameterFunction<T, U, V, W, R> {
    public R apply(T t, U u, V v, W w);
}

If there is more than one parameter, you need to put parentheses around the argument list, like so:

FourParameterFunction<String, Integer, Double, Person, String> myLambda = (a, b, c, d) -> {
    // do something
    return "done something";
};

You can also use array_reduce

array_reduce — Iteratively reduce the array to a single value using a callback function

example:

$tbody = array_reduce($rows, function($a, $b){return $a.="<tr><td>".implode("</td><td>",$b)."</td></tr>";});
$thead = "<tr><th>" . implode("</th><th>", array_keys($rows[0])) . "</th></tr>";

echo "<table>\n$thead\n$tbody\n</table>";

Note: If you use cocoapods in your project, then first run pod deintegrate and rm Podfile.lock

Then open your project folder in any third party code editor like VSCode and do a global search for the ViewController name throwing the error.

1. Rename/fix any wrong names which you find.
2. Save all changes.
3. Clean and build your project.

Everything should work fine now.

This is most often caused when you rename files from within Xcode.

This works for me... EF v3.1.5

context.ModelName.RemoveRange(context.ModelName.ToList());
context.SaveChanges();

I Think this Works:

 testGV.HeaderRow.Cells[0].Text="Date"

I resolved that situation in this way. I created a util method that return a object extracted from request body, using the readValue method of ObjectMapper that is capable of receiving a Reader.

public static <T> T getBody(ResourceRequest request, Class<T> class) {
    T objectFromBody = null;
    try {
        ObjectMapper objectMapper = new ObjectMapper();
        HttpServletRequest httpServletRequest = PortalUtil.getHttpServletRequest(request);
        objectFromBody = objectMapper.readValue(httpServletRequest.getReader(), class);
    } catch (IOException ex) {
        log.error("Error message", ex);
    }
    return objectFromBody;
}

I had the same issue, but I found a good solution here: Stop caching for PHP 5.5.3 in MAMP

Basically find the php.ini file and comment out the OPCache lines. I hope this alternative answer helps others else out as well.

This should do it:

<StackPanel>
    <TextBox x:Name="TheTextBox" />
    <Button Content="Click Me">
        <Button.Style>
            <Style TargetType="Button">
                <Setter Property="IsEnabled" Value="True" />
                <Style.Triggers>
                    <DataTrigger Binding="{Binding Text, ElementName=TheTextBox}" Value="">
                        <Setter Property="IsEnabled" Value="False" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </Button.Style>
    </Button>
</StackPanel>

The input.files attribute is an HTML5 feature. That's why some browsers din't return anything. Simply add a fallback to the plain old input.value (string) if files doesn't exist.

Meanwhile I have found the (for me) perfect solution: nexe, which creates a single executable from a Node.js application including all of its modules.

It's the next best thing to an ideal solution.

If you want first 2 letters and last 2 letters of a string then you can use the following code: name = "India" name[0:2]="In" names[-2:]="ia"

Using gson it is much simpler. Use following code snippet:

 // create a new Gson instance
 Gson gson = new Gson();
 // convert your list to json
 String jsonCartList = gson.toJson(cartList);
 // print your generated json
 System.out.println("jsonCartList: " + jsonCartList);

Converting back from JSON string to your Java object

 // Converts JSON string into a List of Product object
 Type type = new TypeToken<List<Product>>(){}.getType();
 List<Product> prodList = gson.fromJson(jsonCartList, type);

 // print your List<Product>
 System.out.println("prodList: " + prodList);

for (var i in a) {
   console.log(a[i],i)
}

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

You can do it with a pivot query, like this:

select * from (
   select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
   from my_table t
)
pivot 
(
   MIN(DOCUMENT_ID)
   for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Here is a demo on sqlfiddle.com.

Somewhat hacky, but seems to work:

def cumulative_sum(l):
  y = [0]
  def inc(n):
    y[0] += n
    return y[0]
  return [inc(x) for x in l]

I did think that the inner function would be able to modify the y declared in the outer lexical scope, but that didn't work, so we play some nasty hacks with structure modification instead. It is probably more elegant to use a generator.

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

f = open('{}.csv'.format(), 'wb')

If we are talking Visual Studio Code nowadays you set a default formatter in your settings.json:

  // Defines a default formatter which takes precedence over all other formatter settings. 
  // Must be the identifier of an extension contributing a formatter.
  "editor.defaultFormatter": null,

Point to the identifier of any installed extension, i.e.

"editor.defaultFormatter": "esbenp.prettier-vscode"

You can also do so format-specific:

"[html]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[scss]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[sass]": {
    "editor.defaultFormatter": "michelemelluso.code-beautifier"
},

Also see here.

You could also assign other keys for different formatters in your keyboard shortcuts (keybindings.json). By default, it reads:

{
  "key": "shift+alt+f",
  "command": "editor.action.formatDocument",
  "when": "editorHasDocumentFormattingProvider && editorHasDocumentFormattingProvider && editorTextFocus && !editorReadonly"
}

Lastly, if you decide to use the Prettier plugin and prettier.rc, and you want for example different indentation for html, scss, json...

{
    "semi": true,
    "singleQuote": false,
    "trailingComma": "none",
    "useTabs": false,

    "overrides": [
        {
            "files": "*.component.html",
            "options": {
                "parser": "angular",
                "tabWidth": 4
            }
        },
        {
            "files": "*.scss",
            "options": {
                "parser": "scss",
                "tabWidth": 2
            }
        },
        {
            "files": ["*.json", ".prettierrc"],
            "options": {
                "parser": "json",
                "tabWidth": 4
            }
        }
    ]
}

Please try module pexpect. Here is my code:

import pexpect
remove = pexpect.spawn('sudo dpkg --purge mytool.deb')
remove.logfile = open('log/expect-uninstall-deb.log', 'w')
remove.logfile.write('try to dpkg --purge mytool\n')
if remove.expect(['(?i)password.*']) == 0:
    # print "successfull"
    remove.sendline('mypassword')
    time.sleep(2)
    remove.expect(pexpect.EOF,5)
else:
    raise AssertionError("Fail to Uninstall deb package !")

Occurs when the text content of an element is changed through the user interface.

It's not quite an alias for keyup because keyup will fire even if the key does nothing (for example: pressing and then releasing the Control key will trigger a keyup event).

A good way to think about it is like this: it's an event that triggers whenever the input changes. This includes -- but is not limited to -- pressing keys which modify the input (so, for example, Ctrl by itself will not trigger the event, but Ctrl-V to paste some text will), selecting an auto-completion option, Linux-style middle-click paste, drag-and-drop, and lots of other things.

See this page and the comments on this answer for more details.

another way of doing it

ALTER AUTHORIZATION

Try this from the box you are pushing from

    ssh [email protected]

You should then get a welcome response from github and will be fine to then push.

Here is a nice summary table from cppreference.com:

Here, insertion refers to any method which adds one or more elements to the container and erasure refers to any method which removes one or more elements from the container.

Lot of good things have been said above about optimistic and pessimistic locking. One important point to consider is as follows:

When using optimistic locking, we need to cautious of the fact that how will application recover from these failures.

Specially in asynchronous message driven architectures, this can lead of out of order message processing or lost updates.

Failures scenarios need to be thought through.

Based on Mark's answer above (and Geo's comment), I created a two liner version to remove all ASCII exception cases from a string. Provided for people searching for this answer (as I did).

using System.Text;

// Create encoder with a replacing encoder fallback
var encoder = ASCIIEncoding.GetEncoding("us-ascii", 
    new EncoderReplacementFallback(string.Empty), 
    new DecoderExceptionFallback());

string cleanString = encoder.GetString(encoder.GetBytes(dirtyString)); 

Alejandro nailed it, adding clarification to the exception (Ubuntu or Debian) - I don't have the rep to add to the answer itself:

sudoers file: sudo visudo

exception added: www-data ALL=(ALL) NOPASSWD: ALL

i had this problem and i solved it using javascript

 location.reload(true);

you may also use

window.history.forward(1);

to stop the browser back button after user logs out of the application.

Heap allocations are possible for static variables if you use the lazy_static macro as seen in the docs

Using this macro, it is possible to have statics that require code to be executed at runtime in order to be initialized. This includes anything requiring heap allocations, like vectors or hash maps, as well as anything that requires function calls to be computed.

// Declares a lazily evaluated constant HashMap. The HashMap will be evaluated once and
// stored behind a global static reference.

use lazy_static::lazy_static;
use std::collections::HashMap;

lazy_static! {
    static ref PRIVILEGES: HashMap<&'static str, Vec<&'static str>> = {
        let mut map = HashMap::new();
        map.insert("James", vec!["user", "admin"]);
        map.insert("Jim", vec!["user"]);
        map
    };
}

fn show_access(name: &str) {
    let access = PRIVILEGES.get(name);
    println!("{}: {:?}", name, access);
}

fn main() {
    let access = PRIVILEGES.get("James");
    println!("James: {:?}", access);

    show_access("Jim");
}

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

How do I initialize the base (super) class?

class SuperClass(object):
    def __init__(self, x):
        self.x = x

class SubClass(SuperClass):
    def __init__(self, y):
        self.y = y

Use a super object to ensure you get the next method (as a bound method) in the method resolution order. In Python 2, you need to pass the class name and self to super to lookup the bound __init__ method:

 class SubClass(SuperClass):
      def __init__(self, y):
          super(SubClass, self).__init__('x')
          self.y = y

In Python 3, there's a little magic that makes the arguments to super unnecessary - and as a side benefit it works a little faster:

 class SubClass(SuperClass):
      def __init__(self, y):
          super().__init__('x')
          self.y = y

Hardcoding the parent like this below prevents you from using cooperative multiple inheritance:

 class SubClass(SuperClass):
      def __init__(self, y):
          SuperClass.__init__(self, 'x') # don't do this
          self.y = y

Note that __init__ may only return None - it is intended to modify the object in-place.

Something __new__

There's another way to initialize instances - and it's the only way for subclasses of immutable types in Python. So it's required if you want to subclass str or tuple or another immutable object.

You might think it's a classmethod because it gets an implicit class argument. But it's actually a staticmethod. So you need to call __new__ with cls explicitly.

We usually return the instance from __new__, so if you do, you also need to call your base's __new__ via super as well in your base class. So if you use both methods:

class SuperClass(object):
    def __new__(cls, x):
        return super(SuperClass, cls).__new__(cls)
    def __init__(self, x):
        self.x = x

class SubClass(object):
    def __new__(cls, y):
        return super(SubClass, cls).__new__(cls)

    def __init__(self, y):
        self.y = y
        super(SubClass, self).__init__('x')

Python 3 sidesteps a little of the weirdness of the super calls caused by __new__ being a static method, but you still need to pass cls to the non-bound __new__ method:

class SuperClass(object):
    def __new__(cls, x):
        return super().__new__(cls)
    def __init__(self, x):
        self.x = x

class SubClass(object):
    def __new__(cls, y):
        return super().__new__(cls)
    def __init__(self, y):
        self.y = y
        super().__init__('x')

Combining some features of @HYRY and @arun's answers, you can print the top correlations for dataframe df in a single line using:

df.corr().unstack().sort_values().drop_duplicates()

Note: the one downside is if you have 1.0 correlations that are not one variable to itself, the drop_duplicates() addition would remove them

I'm using a parent pom for my projects and wanted to specify the versions in one place, so I used properties to specify the version:

Just pass in the current Context to the Adapter constructor and store it as a field. Then inside the onClick you can use that context to call startActivity().

pseudo-code

public class MyAdapter extends Adapter {
     private Context context;

     public MyAdapter(Context context) {
          this.context = context;     
     }

     public View getView(...){
         View v;
         v.setOnClickListener(new OnClickListener() {
             void onClick() {
                 context.startActivity(...);
             }
         });
     }
}

Well...

? (Optional) indicates your variable may contain a nil value while ! (unwrapper) indicates your variable must have a memory (or value) when it is used (tried to get a value from it) at runtime.

The main difference is that optional chaining fails gracefully when the optional is nil, whereas forced unwrapping triggers a runtime error when the optional is nil.

To reflect the fact that optional chaining can be called on a nil value, the result of an optional chaining call is always an optional value, even if the property, method, or subscript you are querying returns a nonoptional value. You can use this optional return value to check whether the optional chaining call was successful (the returned optional contains a value), or did not succeed due to a nil value in the chain (the returned optional value is nil).

Specifically, the result of an optional chaining call is of the same type as the expected return value, but wrapped in an optional. A property that normally returns an Int will return an Int? when accessed through optional chaining.

var defaultNil : Int?  // declared variable with default nil value
println(defaultNil) >> nil  

var canBeNil : Int? = 4
println(canBeNil) >> optional(4)

canBeNil = nil
println(canBeNil) >> nil

println(canBeNil!) >> // Here nil optional variable is being unwrapped using ! mark (symbol), that will show runtime error. Because a nil optional is being tried to get value using unwrapper

var canNotBeNil : Int! = 4
print(canNotBeNil) >> 4

var cantBeNil : Int = 4
cantBeNil = nil // can't do this as it's not optional and show a compile time error

Here is basic tutorial in detail, by Apple Developer Committee: Optional Chaining

This excellent answer to a similar question (that I could not find before, unfortunately) helped me solve the problem.

Copying Content from referenced answer :

SQL Developer will look in the following location in this order for a tnsnames.ora file

$HOME/.tnsnames.ora
$TNS_ADMIN/tnsnames.ora
TNS_ADMIN lookup key in the registry
/etc/tnsnames.ora ( non-windows )
$ORACLE_HOME/network/admin/tnsnames.ora
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

If your tnsnames.ora file is not getting recognized, use the following procedure:

Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...
In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

Confirm the os is recognizing this environmental variable

From the Windows command line: echo %TNS_ADMIN%

From linux: echo $TNS_ADMIN

Restart SQL Developer Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

There are four ways I've found to put a newline into the minibuffer.

1. C-o

2. C-q C-j

3. C-q 12 (12 is the octal value of newline)

4. C-x o to the main window, kill a newline with C-k, then C-x o back to the minibuffer, yank it with C-y

The collapse package provides the fastest scale function - implemented in C++ using Welfords Online Algorithm:

dat <- data.frame(x = rnorm(1e6, 30, .2), 
                  y = runif(1e6, 3, 5),
                  z = runif(1e6, 10, 20))

library(collapse)
library(microbenchmark)
microbenchmark(fscale(dat), scale(dat))

Unit: milliseconds
        expr       min       lq      mean    median        uq      max neval cld
 fscale(dat)  27.86456  29.5864  38.96896  30.80421  43.79045 313.5729   100  a 
  scale(dat) 357.07130 391.0914 489.93546 416.33626 625.38561 793.2243   100   b

Furthermore: fscale is S3 generic for vectors, matrices and data frames and also supports grouped and/or weighted scaling operations, as well as scaling to arbitrary means and standard deviations.

plt.hist(hmag, 30, range=[6.5, 12.5], facecolor='gray', align='mid')

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        // ... Get the cell
        cell.separatorInset = UIEdgeInsetsMake(0.f, 20.f, 0.f, [UIScreen mainScreen].bounds.size.width - 20);
        // others
        return cell;
}

For any specific cell you want to hide the separator.

Follow the below steps:

1. No need to give any type of header.

2. Select body > form-data and do same as shown in the image.

3. Now in your Django view.py

def post(self, request, *args, **kwargs):
    image = request.FILES["image"]
    data = json.loads(request.data['data'])
    ...
    return Response(...)

4. You can access all the keys (id, uid etc..) from the data variable.

If you use a BlockingCollection to schedule the task, the producer can run the potentially long running task and the consumer can use the TryTake method which has timeout and cancellation token built in.

First, we choose stable (not static) data columns to form a Primary Key, precisely because updating Keys in a Relational database (in which the references are by Key) is something we wish to avoid.

1. For this issue, it doesn't matter if the Key is a Relational Key ("made up from the data"), and thus has Relational Integrity, Power, and Speed, or if the "key" is a Record ID, with none of that Relational Integrity, Power, and Speed. The effect is the same.

2. I state this because there are many posts by the clueless ones, who suggest that this is the exact reason that Record IDs are somehow better than Relational Keys.

3. The point is, the Key or Record ID is migrated to wherever a reference is required.

Second, if you have to change the value of the Key or Record ID, well, you have to change it. Here is the OLTP Standard-compliant method. Note that the high-end vendors do not allow "cascade update".

• Write a proc. Foo_UpdateCascade_tr @ID, where Foo is the table name

• Begin a Transaction

• First INSERT-SELECT a new row in the parent table, from the old row, with the new Key or RID value

• Second, for all child tables, working top to bottom, INSERT-SELECT the new rows, from the old rows, with the new Key or RID value

• Third, DELETE the rows in the child tables that have the old Key or RID value, working bottom to top

• Last, DELETE the row in the parent table that has the old Key or RID value

• Commit the Transaction

Re the Other Answers

The other answers are incorrect.

• Disabling constraints and then enabling them, after UPDATing the required rows (parent plus all children) is not something that a person would do in an online production environment, if they wish to remain employed. That advice is good for single-user databases.

• The need to change the value of a Key or RID is not indicative of a design flaw. It is an ordinary need. That is mitigated by choosing stable (not static) Keys. It can be mitigated, but it cannot be eliminated.

• A surrogate substituting a natural Key, will not make any difference. In the example you have given, the "key" is a surrogate. And it needs to be updated.

  • Please, just surrogate, there is no such thing as a "surrogate key", because each word contradicts the other. Either it is a Key (made up from the data) xor it isn't. A surrogate is not made up from the data, it is explicitly non-data. It has none of the properties of a Key.

• There is nothing "tricky" about cascading all the required changes. Refer to the steps given above.

• There is nothing that can be prevented re the universe changing. It changes. Deal with it. And since the database is a collection of facts about the universe, when the universe changes, the database will have to change. That is life in the big city, it is not for new players.

• People getting married and hedgehogs getting buried are not a problem (despite such examples being used to suggest that it is a problem). Because we do not use Names as Keys. We use small, stable Identifiers, such as are used to Identify the data in the universe.

  • Names, descriptions, etc, exist once, in one row. Keys exist wherever they have been migrated. And if the "key" is a RID, then the RID too, exists wherever it has been migrated.

• Don't update the PK! is the second-most hilarious thing I have read in a while. Add a new column is the most.

Many, if not most, of these solutions rely on arcane syntax, brain-busting regex tricks, or calls to external executables. I would like to propose a simple, bash-only solution that is very easy to understand, and only slightly sub-optimal, performance-wise.

join_by () {
    # Argument #1 is the separator. It can be multi-character.
    # Argument #2, 3, and so on, are the elements to be joined.
    # Usage: join_by ", " "${array[@]}"
    local SEPARATOR="$1"
    shift

    local F=0
    for x in "$@"
    do
        if [[ F -eq 1 ]]
        then
            echo -n "$SEPARATOR"
        else
            F=1
        fi
        echo -n "$x"
    done
    echo
}

Example:

$ a=( 1 "2 2" 3 )
$ join_by ", " "${a[@]}"
1, 2 2, 3
$ 

I'd like to point out that any solution that uses /usr/bin/[ or /usr/bin/printf is inherently slower than my solution, since I use 100% pure bash. As an example of its performance, Here's a demo where I create an array with 1,000,000 random integers, then join them all with a comma, and time it.

$ eval $(echo -n "a=("; x=0 ; while [[ x -lt 1000000 ]]; do echo -n " $RANDOM" ; x=$((x+1)); done; echo " )")
$ time join_by , ${a[@]} >/dev/null
real    0m8.590s
user    0m8.591s
sys     0m0.000s
$ 

Even when I just had one writer and one reader, my issue was that one of the reads was taking too long: longer than the stipulated timeout of 5 seconds. So the writer timed out and caused the error.

So, be careful when reading all entries from a database especially from one which the size of the table grows over time.

r = requests.get('https://api.github.com', auth=('user', 'pass'))

r is a response. It has a request attribute which has the information you need.

r.request.allow_redirects  r.request.headers          r.request.register_hook
r.request.auth             r.request.hooks            r.request.response
r.request.cert             r.request.method           r.request.send
r.request.config           r.request.params           r.request.sent
r.request.cookies          r.request.path_url         r.request.session
r.request.data             r.request.prefetch         r.request.timeout
r.request.deregister_hook  r.request.proxies          r.request.url
r.request.files            r.request.redirect         r.request.verify

r.request.headers gives the headers:

{'Accept': '*/*',
 'Accept-Encoding': 'identity, deflate, compress, gzip',
 'Authorization': u'Basic dXNlcjpwYXNz',
 'User-Agent': 'python-requests/0.12.1'}

Then r.request.data has the body as a mapping. You can convert this with urllib.urlencode if they prefer:

import urllib
b = r.request.data
encoded_body = urllib.urlencode(b)

depending on the type of the response the .data-attribute may be missing and a .body-attribute be there instead.
