There is one thing to remember, when you are searching the object in array on the basis of more than one condition then use $elemMatch

Person.update(
   {
     _id: 5,
     grades: { $elemMatch: { grade: { $lte: 90 }, mean: { $gt: 80 } } }
   },
   { $set: { "grades.$.std" : 6 } }
)

here is the docs

In answer to this part of the original question "Is there any other C# method for hashing passwords" You can achieve this using ASP.NET Identity v3.0 https://www.nuget.org/packages/Microsoft.AspNet.Identity.EntityFramework/3.0.0-rc1-final

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.AspNet.Identity;
using System.Security.Principal;

namespace HashTest{


    class Program
    {
        static void Main(string[] args)
        {

            WindowsIdentity wi = WindowsIdentity.GetCurrent();

            var ph = new PasswordHasher<WindowsIdentity>();

            Console.WriteLine(ph.HashPassword(wi,"test"));

            Console.WriteLine(ph.VerifyHashedPassword(wi,"AQAAAAEAACcQAAAAEA5S5X7dmbx/NzTk6ixCX+bi8zbKqBUjBhID3Dg1teh+TRZMkAy3CZC5yIfbLqwk2A==","test"));

        }
    }


}

In case this is useful to anyone I had this same issue. I was bringing in a footer into a web page via jQuery. Inside that footer were some Google scripts for ads and retargeting. I had to move those scripts from the footer and place them directly in the page and that eliminated the notice.

JS Code

    $("#submit").click(function() { 
    //get input field values
    var name            = $('#name').val(); 
    var email           = $('#email').val();
    var message         = $('#comment').val();
    var flag = true;
    /********validate all our form fields***********/
    /* Name field validation  */
    if(name==""){ 
        $('#name').css('border-color','red'); 
        flag = false;
    }
    /* email field validation  */
    if(email==""){ 
        $('#email').css('border-color','red'); 
        flag = false;

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

Image playbutton;
try
{
    playbutton = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

Image frame;
try
{
    frame = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

using (frame)
{
    using (var bitmap = new Bitmap(width, height))
    {
        using (var canvas = Graphics.FromImage(bitmap))
        {
            canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
            canvas.DrawImage(frame,
                             new Rectangle(0,
                                           0,
                                           width,

I have seen this in the situation when the selenium driven Chrome window was opened too small. The element to be clicked on was out of the viewport and therefore it was failing.

That sounds logical... real user would have to either resize the window or scroll so that it is possible to see the element and in fact click on it.

After instructing the selenium driver to set the window size appropriately this issues went away for me. The webdriver API is decribed here.

I suggest Oj as it is waaaaaay faster than the standard JSON library.

https://github.com/ohler55/oj

(see performance comparisons here)

Had the same issue, but executing the queries alone will not help. To fix this I did the following,

1. Set old_passwords=0 in my.cnf file
2. Restart mysql
3. Login to mysql as root user
4. Execute FLUSH PRIVILEGES;

If you want to refer to a nested table by multiple keys you can just assign them to separate keys. The tables are not duplicated, and still reference the same values.

arr = {}
apples = {'a', "red", 5 }
arr.apples = apples
arr[1] = apples

This code block lets you iterate through all the key-value pairs in a table (http://lua-users.org/wiki/TablesTutorial):

for k,v in pairs(t) do
 print(k,v)
end

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
SimpleDateFormat output = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date d = sdf.parse(time);
String formattedTime = output.format(d);

This works. You have to use two SimpleDateFormats, one for input and one for output, but it will give you just what you are wanting.

var ofd = new Microsoft.Win32.OpenFileDialog() {Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"}; 
var result = ofd.ShowDialog();
if (result == false) return;
textBox1.Text = ofd.FileName;

Use:

$filenameFormat = "mybackup.zip" + " " + (Get-Date -Format "yyyy-MM-dd")
Rename-Item -Path "C:\temp\mybackup.zip" -NewName $filenameFormat

EntityManager interface is similar to sessionFactory in hibernate. EntityManager under javax.persistance package but session and sessionFactory under org.hibernate.Session/sessionFactory package.

Entity manager is JPA specific and session/sessionFactory are hibernate specific.

This isn't pretty, but it works:

<script type="text/javascript">
  document.write('<script type="text/javascript" src="other.js"></script>');
</script>

<script type="text/javascript">
  functionFromOther();
</script>

Or

<script type="text/javascript">
  document.write('<script type="text/javascript" src="other.js"></script>');
  window.onload = function() {
    functionFromOther();
  };
</script>

The script must be included either in a separate <script> tag or before window.onload().

This will not work:

<script type="text/javascript">
  document.write('<script type="text/javascript" src="other.js"></script>');
  functionFromOther(); // Error
</script>

The same can be done with creating a node, as Pointy did, but only in FF. You have no guarantee when the script will be ready in other browsers.

Being an XML Purist I really hate this. But it does work predictably. You could easily wrap those ugly document.write()s so you don't have to look at them. You could even do tests and create a node and append it then fall back on document.write().

public static void set(Map<String, String> newenv) throws Exception {
    Class[] classes = Collections.class.getDeclaredClasses();
    Map<String, String> env = System.getenv();
    for(Class cl : classes) {
        if("java.util.Collections$UnmodifiableMap".equals(cl.getName())) {
            Field field = cl.getDeclaredField("m");
            field.setAccessible(true);
            Object obj = field.get(env);
            Map<String, String> map = (Map<String, String>) obj;
            map.clear();
            map.putAll(newenv);
        }
    }
}

Or to add/update a single var and removing the loop as per thejoshwolfe's suggestion.

@SuppressWarnings({ "unchecked" })
  public static void updateEnv(String name, String val) throws ReflectiveOperationException {
    Map<String, String> env = System.getenv();
    Field field = env.getClass().getDeclaredField("m");
    field.setAccessible(true);
    ((Map<String, String>) field.get(env)).put(name, val);
  }

This will work fine for you

Writing to stdout

If you want something that, like std::cout, writes to your application's standard output, you can simply do the following (credit to CapelliC):

QTextStream(stdout) << "string to print" << endl;

If you want to avoid creating a temporary QTextStream object, follow Yakk's suggestion in the comments below of creating a function to return a static handle for stdout:

inline QTextStream& qStdout()
{
    static QTextStream r{stdout};
    return r;
}

...

foreach(QString x, strings)
    qStdout() << x << endl;

Remember to flush the stream periodically to ensure the output is actually printed.

Writing to stderr

Note that the above technique can also be used for other outputs. However, there are more readable ways to write to stderr (credit to Goz and the comments below his answer):

qDebug() << "Debug Message";    // CAN BE REMOVED AT COMPILE TIME!
qWarning() << "Warning Message";
qCritical() << "Critical Error Message";
qFatal("Fatal Error Message");  // WILL KILL THE PROGRAM!

qDebug() is closed if QT_NO_DEBUG_OUTPUT is turned on at compile-time.

(Goz notes in a comment that for non-console apps, these can print to a different stream than stderr.)

NOTE: All of the Qt print methods assume that const char* arguments are ISO-8859-1 encoded strings with terminating \0 characters.

Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified his example to do this here: http://jsfiddle.net/QLfMU/116/

Use below code to print the error code :

echo mysqli_errno($this->db_link);

Error code will give you better idea about the error.

Or add this part

<script type="text/javascript">

    var mySpan = document.createElement("span");
    mySpan.innerHTML = "This is my span!";

    mySpan.style.color = "red";
    document.body.appendChild(mySpan);

    alert("Why does the span change after this alert? Not before?");

</script>

after the HTML, like:

    <html>
    <head>...</head>
    <body>...</body>
   <script type="text/javascript">
        var mySpan = document.createElement("span");
        mySpan.innerHTML = "This is my span!";

        mySpan.style.color = "red";
        document.body.appendChild(mySpan);

        alert("Why does the span change after this alert? Not before?");

    </script>

One difference we can note in Windows is:

If you use Runtime.getRuntime().exec("rmiregistry 1024");

you can see rmiregistry.exe process will run in your Task Manager

whereas if you use Registry registry = LocateRegistry.createRegistry(1024);

you can not see the process running in Task Manager,

I think Java handles it in a different way.

and this is my server.policy file

Before running the the application, make sure that you killed all your existing javaw.exe and rmiregistry.exe corresponds to your rmi programs which are already running.

The following code works for me by using Registry.LocateRegistry() or

Runtime.getRuntime.exec("");


// Standard extensions get all permissions by default

grant {
    permission java.security.AllPermission;
};

VM argument

-Djava.rmi.server.codebase=file:\C:\Users\Durai\workspace\RMI2\src\

Code:

package server;    

import java.rmi.Naming;
import java.rmi.RMISecurityManager;
import java.rmi.Remote;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;

public class HelloServer 
{
  public static void main (String[] argv) 
  {
    try {

        if(System.getSecurityManager()==null){
            System.setProperty("java.security.policy","C:\\Users\\Durai\\workspace\\RMI\\src\\server\\server.policy");
            System.setSecurityManager(new RMISecurityManager());
        }

 Runtime.getRuntime().exec("rmiregistry 1024");

 //     Registry registry = LocateRegistry.createRegistry(1024);
   //   registry.rebind ("Hello", new Hello ("Hello,From Roseindia.net pvt ltd!"));
   //Process process = Runtime.getRuntime().exec("C:\\Users\\Durai\\workspace\\RMI\\src\\server\\rmi_registry_start.bat");

        Naming.rebind ("//localhost:1024/Hello",new Hello ("Hello,From Roseindia.net pvt ltd!")); 
      System.out.println ("Server is connected and ready for operation.");
    } 
    catch (Exception e) {
      System.out.println ("Server not connected: " + e);
      e.printStackTrace();
    }
  }
}

There are many articles about writing code to import an excel file, but this is a manual/shortcut version:

If you don't need to import your Excel file programmatically using code you can do it very quickly using the menu in SQL Management Studio.

The quickest way to get your Excel file into SQL is by using the import wizard:

1. Open SSMS (Sql Server Management Studio) and connect to the database where you want to import your file into.
2. Import Data: in SSMS in Object Explorer under 'Databases' right-click the destination database, select Tasks, Import Data. An import wizard will pop up (you can usually just click 'Next' on the first screen).

3. The next window is 'Choose a Data Source', select Excel:

   • In the 'Data Source' dropdown list select Microsoft Excel (this option should appear automatically if you have excel installed).

   • Click the 'Browse' button to select the path to the Excel file you want to import.

   • Select the version of the excel file (97-2003 is usually fine for files with a .XLS extension, or use 2007 for newer files with a .XLSX extension)
   • Tick the 'First Row has headers' checkbox if your excel file contains headers.
   • Click next.

4. On the 'Choose a Destination' screen, select destination database:
   • Select the 'Server name', Authentication (typically your sql username & password) and select a Database as destination. Click Next.

5. On the 'Specify Table Copy or Query' window:

   • For simplicity just select 'Copy data from one or more tables or views', click Next.

6. 'Select Source Tables:' choose the worksheet(s) from your Excel file and specify a destination table for each worksheet. If you don't have a table yet the wizard will very kindly create a new table that matches all the columns from your spreadsheet. Click Next.

7. Click Finish.

<context:annotation-config>

Only resolves the @Autowired and @Qualifer annotations, that's all, it about the Dependency Injection, There are other annotations that do the same job, I think how @Inject, but all about to resolve DI through annotations.

Be aware, even when you have declared the <context:annotation-config> element, you must declare your class how a Bean anyway, remember we have three available options

• XML: <bean>
• @Annotations: @Component, @Service, @Repository, @Controller
• JavaConfig: @Configuration, @Bean

Now with

<context:component-scan>

It does two things:

• It scans all the classes annotated with @Component, @Service, @Repository, @Controller and @Configuration and create a Bean
• It does the same job how <context:annotation-config> does.

Therefore if you declare <context:component-scan>, is not necessary anymore declare <context:annotation-config> too.

Thats all

A common scenario was for example declare only a bean through XML and resolve the DI through annotations, for example

<bean id="serviceBeanA" class="com.something.CarServiceImpl" />
<bean id="serviceBeanB" class="com.something.PersonServiceImpl" />
<bean id="repositoryBeanA" class="com.something.CarRepository" />
<bean id="repositoryBeanB" class="com.something.PersonRepository" />

We have only declared the beans, nothing about <constructor-arg> and <property>, the DI is configured in their own classes through @Autowired. It means the Services use @Autowired for their Repositories components and the Repositories use @Autowired for the JdbcTemplate, DataSource etc..components

Cast one of the integers/both of the integer to float to force the operation to be done with floating point Math. Otherwise integer Math is always preferred. So:

1. v = (float)s / t;
2. v = (float)s / (float)t;

 private void HighLightGridRows()
 {            
     Debugger.Launch();
     for (int i = 0; i < dtgvAppSettings.Rows.Count; i++)
     {
         String key = dtgvAppSettings.Rows[i].Cells["Key"].Value.ToString();
         if (key.ToLower().Contains("applicationpath") == true)
         {
             dtgvAppSettings.Rows[i].DefaultCellStyle.BackColor = Color.Yellow;
         }
     }
 }

To send an mms for Android 4.0 api 14 or higher without permission to write apn settings, you can use this library: Retrieve mnc and mcc codes from android, then call

Carrier c = Carrier.getCarrier(mcc, mnc);
if (c != null) {
    APN a = c.getAPN();
    if (a != null) {
        String mmsc = a.mmsc;
        String mmsproxy = a.proxy; //"" if none
        int mmsport = a.port; //0 if none
    }
}

To use this, add Jsoup and droid prism jar to the build path, and import com.droidprism.*;

Although I don't know what RDBMS you are using, you probably need to give the whole column specification, not just say that you now want it to be nullable. For example, if it's currently INT NOT NULL, you should issue ALTER TABLE Merchant_Pending_Functions Modify NumberOfLocations INT.

I am pretty amazed no one had mentioned this hack so far:

python -c "import sys; set(map(sys.stdout.write,sys.stdin))"

in python2 you can drop the set() call, but it would word either way

I have added this answer only because the problem is explained based on more complex data pattern and I found it hard to understand here.

I created a fairly simple application. This error occurred inside Edit POST action. The action accepted ViewModel as an input parameter. The reason for using the ViewModel was to make some calculation before the record was saved.

Once the action passed through validation such as if(ModelState.IsValid), my wrongdoing was to project values from ViewModel into a completely new instance of Entity. I thought I'd have to create a new instance to store updated data and then saved such instance.

What I had realised later was that I had to read the record from database:

Student student = db.Students.Find(s => s.StudentID == ViewModel.StudentID);

and updated this object. Everything works now.

you can also use: s.lower() in str.lower()

$('#item1 span').html(); Its working with my code

I think the following way is more clear and useful for nested ng-repeats. Check it out on Plunker.

Quote from this thread:

<html ng-app="plunker">
    <head>

                    $scope.mytabs = [
             {

                     { value: "value4", checked: false }
                 ]

                 ]
             }
                    ]
                    $scope.selected = []
                    $scope.checkValues = function () {
                        angular.forEach($scope.mytabs, function (value, index) {
                         var selectedItems = $filter('filter')(value.values, { checked: true });
                         angular.forEach(selectedItems, function (value, index) {
                             $scope.selected.push(value);
                         });

                        });
                    console.log($scope.selected);

Make a truth table and use SUMPRODUCT to get the values. Copy this into cell B1 on Sheet2 and copy down as far as you need:
=SUMPRODUCT(--($A1 = Sheet1!$A:$A), Sheet1!$B:$B)
the part that creates the truth table is:
--($A1 = Sheet1!$A:$A)
This returns an array of 0's and 1's. 1 when the values match and a 0 when they don't. Then the comma after that will basically do what I call "funny" matrix multiplication and will return the result. I may have misunderstood your question though, are there duplicate values in Column A of Sheet1?

You can use strstream. It's formally deprecated, but it's still a great tool if you need to work with C strings, i think.

char result[100]; // max size 100
std::ostrstream s(result, sizeof result - 1);

s << one << two << std::ends;
result[99] = '\0';

This will write one and then two into the stream, and append a terminating \0 using std::ends. In case both strings could end up writing exactly 99 characters - so no space would be left writing \0 - we write one manually at the last position.

For ListBox / DropDown in MVC5 - i've found this to work for me sofar:

in Model:

[Required(ErrorMessage = "- Select item -")]
 public List<string> SelectedItem { get; set; }
 public List<SelectListItem> AvailableItemsList { get; set; }

in View:

@Html.ListBoxFor(model => model.SelectedItem, Model.AvailableItemsList)
@Html.ValidationMessageFor(model => model.SelectedItem, "", new { @class = "text-danger" })

Just use $interval

Here is your code modified. http://plnkr.co/edit/m7psQ5rwx4w1yAwAFdyr?p=preview

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

app.controller('TestCtrl', function ($scope, $interval) {
   $scope.testValue = 0;

    $interval(function() {
        $scope.testValue++;
    }, 500);
});

You need the following permissions in your manifest file:

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

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

An English dictionary defines the words append and extend as:

append: add (something) to the end of a written document.
extend: make larger. Enlarge or expand

With that knowledge, now let's understand

1) The difference between append and extend

append:

• Appends any Python object as-is to the end of the list (i.e. as a the last element in the list).
• The resulting list may be nested and contain heterogeneous elements (i.e. list, string, tuple, dictionary, set, etc.)

extend:

• Accepts any iterable as its argument and makes the list larger.
• The resulting list is always one-dimensional list (i.e. no nesting) and it may contain heterogeneous elements in it (e.g. characters, integers, float) as a result of applying list(iterable).

2) Similarity between append and extend

• Both take exactly one argument.
• Both modify the list in-place.
• As a result, both returns None.

Example

lis = [1, 2, 3]

# 'extend' is equivalent to this
lis = lis + list(iterable)

# 'append' simply appends its argument as the last element to the list
# as long as the argument is a valid Python object
list.append(object)

A String is an immutable character array.

A StringBuffer is a mutable character array. Often converted back to String when done mutating.

Since both are an array, the maximum size for both is equal to the maximum size of an integer, which is 2^31-1 (see JavaDoc, also check out the JavaDoc for both String and StringBuffer).This is because the .length argument of an array is a primitive int. (See Arrays).

Since assertThat which was the old answer is now deprecated, I am posting the correct solution:

assertTrue(objectUnderTest instanceof TargetObject);

The ugly but simpler way: delete your local folder, and clone the remote repository again.

EasyFSM is a dynamic Java Library which can be used to implement an FSM.

You can find documentation for the same at : Finite State Machine in Java

Also, you can download the library at : Java FSM Library : DynamicEasyFSM

Ok, for @AndrewS solution to work with v7 appCompat library:

<menu 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:someNamespace="http://schemas.android.com/apk/res-auto" >

    <item
        android:id="@+id/saved_badge"
        someNamespace:showAsAction="always"
        android:icon="@drawable/shape_notification" />

</menu>

.

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    menu.clear();
    inflater.inflate(R.menu.main, menu);

    MenuItem item = menu.findItem(R.id.saved_badge);
    MenuItemCompat.setActionView(item, R.layout.feed_update_count);
    View view = MenuItemCompat.getActionView(item);
    notifCount = (Button)view.findViewById(R.id.notif_count);
    notifCount.setText(String.valueOf(mNotifCount));
}

private void setNotifCount(int count){
    mNotifCount = count;
    supportInvalidateOptionsMenu();
}

The rest of the code is the same.

for people who need CGO enabled and cross compile from OSX targeting windows

I needed CGO enabled while compiling for windows from my mac since I had imported the https://github.com/mattn/go-sqlite3 and it needed it. Compiling according to other answers gave me and error:

/usr/local/go/src/runtime/cgo/gcc_windows_amd64.c:8:10: fatal error: 'windows.h' file not found

If you're like me and you have to compile with CGO. This is what I did:

1.We're going to cross compile for windows with a CGO dependent library. First we need a cross compiler installed like mingw-w64

brew install mingw-w64

This will probably install it here /usr/local/opt/mingw-w64/bin/.

2.Just like other answers we first need to add our windows arch to our go compiler toolchain now. Compiling a compiler needs a compiler (weird sentence) compiling go compiler needs a separate pre-built compiler. We can download a prebuilt binary or build from source in a folder eg: ~/Documents/go now we can improve our Go compiler, according to top answer but this time with CGO_ENABLED=1 and our separate prebuilt compiler GOROOT_BOOTSTRAP(Pooya is my username):

cd /usr/local/go/src
sudo GOOS=windows GOARCH=amd64 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean
sudo GOOS=windows GOARCH=386 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean

3.Now while compiling our Go code use mingw to compile our go file targeting windows with CGO enabled:

GOOS="windows" GOARCH="386" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/i686-w64-mingw32-gcc" go build hello.go
GOOS="windows" GOARCH="amd64" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/x86_64-w64-mingw32-gcc" go build hello.go

It is not an issue it is because of caching...

To overcome this add a timestamp to your endpoint call, e.g. axios.get('/api/products').

After timestamp it should be axios.get(/api/products?${Date.now()}.

It will resolve your 304 status code.

        // Find a book by its ID.
        Book result = Books.Find(
        delegate(Book bk)
        {
            return bk.ID == IDtoFind;
        }
        );
        if (result != null)
        {
            DisplayResult(result, "Find by ID: " + IDtoFind);   
        }
        else
        {
            Console.WriteLine("\nNot found: {0}", IDtoFind);
        }

You can do something like req.param('tagId')

It was a limitation of the technology at the time it was created. My answer copied over from Programmers.SE:

From one of the original HTML drafts:

NOTE: In the initial design for forms, multi-line text fields were supported by the Input element with TYPE=TEXT. Unfortunately, this causes problems for fields with long text values. SGML's default (Reference Quantity Set) limits the length of attribute literals to only 240 characters. The HTML 2.0 SGML declaration increases the limit to 1024 characters.

Here is the sample code.

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

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

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

Edit 1

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

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

df = df.reindex(sorted(df.columns), axis=1)

This assumes that sorting the column names will give the order you want. If your column names won't sort lexicographically (e.g., if you want column Q10.3 to appear after Q9.1), you'll need to sort differently, but that has nothing to do with pandas.

You don't need a custom control, just put your container in a border element:

<Border BorderBrush="#FF000000" BorderThickness="1" CornerRadius="8">
   <Grid/>
</Border>

You can replace the <Grid/> with any of the layout containers...

I believe SET is ANSI standard whereas the SELECT is not. Also note the different behavior of SET vs. SELECT in the example below when a value is not found.

declare @var varchar(20)
set @var = 'Joe'
set @var = (select name from master.sys.tables where name = 'qwerty')
select @var /* @var is now NULL */

set @var = 'Joe'
select @var = name from master.sys.tables where name = 'qwerty'
select @var /* @var is still equal to 'Joe' */

Try this :

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id()); 
            echo "<b>".$_product->get_title().'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
        } 
?>

To get Product Image and Regular & Sale Price:

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id() );
            //product image
            $getProductDetail = wc_get_product( $values['product_id'] );
            echo $getProductDetail->get_image(); // accepts 2 arguments ( size, attr )

            echo "<b>".$_product->get_title() .'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
            /*Regular Price and Sale Price*/
            echo "Regular Price: ".get_post_meta($values['product_id'] , '_regular_price', true)."<br>";
            echo "Sale Price: ".get_post_meta($values['product_id'] , '_sale_price', true)."<br>";
        }
?>

This works on Python 2 (but not Python 3):

>>> 'foobar'.encode('rot13')
'sbbone'

"use strict";

var constants = Object.freeze({
    "p": 3.141592653589793 ,
    "e": 2.718281828459045 ,
    "i": Math.sqrt(-1)
});

constants.p;        // -> 3.141592653589793
constants.p = 3;    // -> TypeError: Cannot assign to read only property 'p' …
constants.p;        // -> 3.141592653589793

delete constants.p; // -> TypeError: Unable to delete property.
constants.p;        // -> 3.141592653589793

See Object.freeze. You can use const if you want to make the constants reference read-only as well.

Use vars(module) then filter out anything that isn't a function using inspect.isfunction:

import inspect
import my_module

my_module_functions = [f for _, f in vars(my_module).values() if inspect.isfunction(f)]

The advantage of vars over dir or inspect.getmembers is that it returns the functions in the order they were defined instead of sorted alphabetically.

Also, this will include functions that are imported by my_module, if you want to filter those out to get only functions that are defined in my_module, see my question Get all defined functions in Python module.

The sledgehammer is to remove every known host in one fell swoop:

rm ~/.ssh/known_hosts

I come up against this as we use small subnets of short-lived servers from a jump box, and frequently have internal IP address reuse of servers that share the same ssh key.

Most answers here are not correct as they would add bottom space to the last <li> as well, so they are not adding space ONLY in between <li> !

The most accurate and efficient solution is the following:

li.menu-item:not(:last-child) { 
   margin-bottom: 3px;  
}

Explanation: by using :not(:last-child) the style will be applie to all items (li.menu-item) but the last one.

Knockout's documentation also mentions a much cleaner way of passing extra parameters to functions bound using an on-click binding using function.bind like this:

<button data-bind="click: myFunction.bind($data, 'param1', 'param2')">
    Click me
</button>

I know this is old, however many solutions I see above have an issue with the image/video being too large for the container so not actually acting like background-size cover. However, I decided to make "utility classes" so that it would work for images and videos. You simply give the container the class .media-cover-wrapper and the media item itself the class .media-cover

Then you have the following jQuery:

function adjustDimensions(item, minW, minH, maxW, maxH) {
  item.css({
  minWidth: minW,
  minHeight: minH,
  maxWidth: maxW,
  maxHeight: maxH
  });
} // end function adjustDimensions

function mediaCoverBounds() {
  var mediaCover = $('.media-cover');

  mediaCover.each(function() {
   adjustDimensions($(this), '', '', '', '');
   var mediaWrapper = $(this).parent();
   var mediaWrapperWidth = mediaWrapper.width();
   var mediaWrapperHeight = mediaWrapper.height();
   var mediaCoverWidth = $(this).width();
   var mediaCoverHeight = $(this).height();
   var maxCoverWidth;
   var maxCoverHeight;

   if (mediaCoverWidth > mediaWrapperWidth && mediaCoverHeight > mediaWrapperHeight) {

     if (mediaWrapperHeight/mediaWrapperWidth > mediaCoverHeight/mediaCoverWidth) {
       maxCoverWidth = '';
       maxCoverHeight = '100%';
     } else {
       maxCoverWidth = '100%';
       maxCoverHeight = '';
     } // end if

     adjustDimensions($(this), '', '', maxCoverWidth, maxCoverHeight);
   } else {
     adjustDimensions($(this), '100%', '100%', '', '');
   } // end if
 }); // end mediaCover.each
} // end function mediaCoverBounds

When calling it make sure to take care of page resizing:

mediaCoverBounds();

$(window).on('resize', function(){
  mediaCoverBounds();
});

Then the following CSS:

.media-cover-wrapper {
  position: relative;
  overflow: hidden;
}

.media-cover-wrapper .media-cover {
  position: absolute;
  z-index: -1;
  top: 50%;
  left: 50%;
  -ms-transform: translate(-50%, -50%);
  -moz-transform: translate(-50%, -50%);
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

Yeah it may require jQuery but it responds quite well and acts exactly like background-size: cover and you can use it on image and/or videos to get that extra SEO value.

This is actually a gaping hole in the C# language. There is no way to define a string that cannot be null. This causes problems as simple as the one you are describing, which forces programmers to make a decision they shouldn't have to make, since in many cases NULL and String.Empty mean the same thing. That, in turn, can later force other programmers to have to handle both NULL and String.Empty, which is annoying.

A bigger problem is that databases allow you to define fields that map to a C# string, but database fields can be defined as NOT NULL. So, there is no way to accurately represent, say, a varchar( 100 ) NOT NULL field in SQL Server using a C# type.

Other languages, such as Spec #, do allow this.

In my opinion, C#'s inability to define a string that doesn't allow null is just as bad as its previous inability to define an int that does allow null.

To completely answer your question: I always use empty string for default initialization because it is more similar to how database data types work. (Edit: This statement was very unclear. It should read "I use empty string for default initialization when NULL is a superfluous state, much in the same way I set up a database column as NOT NULL if NULL would be a superfluous state. Similarly, many of my DB columns are set up as NOT NULL, so when I bring those into a C# string, the string will be empty or have a value, but will never be NULL. In other words, I only initialize a string to NULL if null has a meaning that is distinct from the meaning of String.Empty, and I find that case to be less than common (but people here have given legitimate examples of this case).")

A string like "Hello World" to hex format: 48656C6C6F20576F726C64.

Ah, here you go:

#include <string>

std::string string_to_hex(const std::string& input)
{
    static const char hex_digits[] = "0123456789ABCDEF";

    std::string output;
    output.reserve(input.length() * 2);
    for (unsigned char c : input)
    {
        output.push_back(hex_digits[c >> 4]);
        output.push_back(hex_digits[c & 15]);
    }
    return output;
}

#include <stdexcept>

int hex_value(unsigned char hex_digit)
{
    static const signed char hex_values[256] = {
        -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1,

        int lo = hex_value(*it++);
        output.push_back(hi << 4 | lo);

(This assumes that a char has 8 bits, so it's not very portable, but you can take it from here.)

First of all, finish() doesn't destroy your process and free up the memory. It just removes the activity from the activity stack. You'd need to kill the process, which is answered in a bunch of questions (since this is being asked several times).

But the proper answer is - Don't do it. the Android OS will automatically free up memory when it needs memory. By not freeing up memory, your app will start up faster if the user gets back to it.

Please see here for a great write-up on the topic.

Just gonna throw this in here since I encountered the same error but for VERY different reasons.

I'm serving via node/express/jade and had ported an old jade file over. One of the lines was to not bork when Typekit failed:

script(type='text/javascript')
  try{Typekit.load();}catch(e){}

It seemed innocuous enough, but I finally realized that for jade script blocks where you're adding content you need a .:

script(type='text/javascript').
  try{Typekit.load();}catch(e){}

Simple, but tricky.

Note the guidelines for performing work on a UI thread, collected on my blog:

• Don't block the UI thread for more than 50ms at a time.
• You can schedule ~100 continuations on the UI thread per second; 1000 is too much.

There are two techniques you should use:

1) Use ConfigureAwait(false) when you can.

E.g., await MyAsync().ConfigureAwait(false); instead of await MyAsync();.

ConfigureAwait(false) tells the await that you do not need to resume on the current context (in this case, "on the current context" means "on the UI thread"). However, for the rest of that async method (after the ConfigureAwait), you cannot do anything that assumes you're in the current context (e.g., update UI elements).

For more information, see my MSDN article Best Practices in Asynchronous Programming.

2) Use Task.Run to call CPU-bound methods.

You should use Task.Run, but not within any code you want to be reusable (i.e., library code). So you use Task.Run to call the method, not as part of the implementation of the method.

So purely CPU-bound work would look like this:

// Documentation: This method is CPU-bound.
void DoWork();

Which you would call using Task.Run:

await Task.Run(() => DoWork());

Methods that are a mixture of CPU-bound and I/O-bound should have an Async signature with documentation pointing out their CPU-bound nature:

// Documentation: This method is CPU-bound.
Task DoWorkAsync();

Which you would also call using Task.Run (since it is partially CPU-bound):

await Task.Run(() => DoWorkAsync());

Try:

public class Main { 
    public static void main(String[] args) {
        String line = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
        String[] tokens = line.split(",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)", -1);
        for(String t : tokens) {
            System.out.println("> "+t);
        }
    }
}

Output:

> foo
> bar
> c;qual="baz,blurb"
> d;junk="quux,syzygy"

In other words: split on the comma only if that comma has zero, or an even number of quotes ahead of it.

Or, a bit friendlier for the eyes:

public class Main { 
    public static void main(String[] args) {
        String line = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";

        String otherThanQuote = " [^\"] ";
        String quotedString = String.format(" \" %s* \" ", otherThanQuote);
        String regex = String.format("(?x) "+ // enable comments, ignore white spaces
                ",                         "+ // match a comma
                "(?=                       "+ // start positive look ahead
                "  (?:                     "+ //   start non-capturing group 1
                "    %s*                   "+ //     match 'otherThanQuote' zero or more times
                "    %s                    "+ //     match 'quotedString'
                "  )*                      "+ //   end group 1 and repeat it zero or more times
                "  %s*                     "+ //   match 'otherThanQuote'
                "  $                       "+ // match the end of the string
                ")                         ", // stop positive look ahead
                otherThanQuote, quotedString, otherThanQuote);

        String[] tokens = line.split(regex, -1);
        for(String t : tokens) {
            System.out.println("> "+t);
        }
    }
}

which produces the same as the first example.

EDIT

As mentioned by @MikeFHay in the comments:

I prefer using Guava's Splitter, as it has saner defaults (see discussion above about empty matches being trimmed by String#split(), so I did:

Splitter.on(Pattern.compile(",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)"))

This should work as well. Use quotes to maintain space

<string name="spelatonertext3">"-4,  5, -5,   6,  -6,"</string>

This solved it for me:
https://gist.github.com/beccasaurus/929007/a8f820b153a1cfdee3d06a9c0a1d7ebfced8bb77

TL;DR:
Problem:
localhost returns expected content, remote IP alters 400 content to "Bad Request"
Solution:
Adding <httpErrors existingResponse="PassThrough"></httpErrors> to web.config/configuration/system.webServer solved this for me; now all servers (local & remote) return the exact same content (generated by me) regardless of the IP address and/or HTTP code I return.

Or, the most performance-friendly way is to overload drawRect, simply like that:

@property (assign) BOOL drawsRightLine;
@property (assign) BOOL drawsLeftLine;
@property (strong, nonatomic) UIColor * lineColor;

@end

@implementation TPActionSheetButton

- (void) drawRect:(CGRect)rect
{
    CGContextRef ctx = UIGraphicsGetCurrentContext();

    CGContextSetLineWidth(ctx, 0.5f * [[UIScreen mainScreen] scale]);
    CGFloat red, green, blue, alpha;
    [self.lineColor getRed:&red green:&green blue:&blue alpha:&alpha];
    CGContextSetRGBStrokeColor(ctx, red, green, blue, alpha);

    if(self.drawsTopLine) {
        CGContextBeginPath(ctx);
        CGContextMoveToPoint(ctx, CGRectGetMinX(rect), CGRectGetMinY(rect));
        CGContextAddLineToPoint(ctx, CGRectGetMaxX(rect), CGRectGetMinY(rect));
        CGContextStrokePath(ctx);
    }
    if(self.drawsBottomLine) {
        CGContextBeginPath(ctx);
        CGContextMoveToPoint(ctx, CGRectGetMinX(rect), CGRectGetMaxY(rect));
        CGContextAddLineToPoint(ctx, CGRectGetMaxX(rect), CGRectGetMaxY(rect));
        CGContextStrokePath(ctx);
    }
    if(self.drawsLeftLine) {
        CGContextBeginPath(ctx);
        CGContextMoveToPoint(ctx, CGRectGetMinX(rect), CGRectGetMinY(rect));
        CGContextAddLineToPoint(ctx, CGRectGetMinX(rect), CGRectGetMaxY(rect));
        CGContextStrokePath(ctx);
    }
    if(self.drawsRightLine) {
        CGContextBeginPath(ctx);
        CGContextMoveToPoint(ctx, CGRectGetMaxX(rect), CGRectGetMinY(rect));
        CGContextAddLineToPoint(ctx, CGRectGetMaxX(rect), CGRectGetMaxY(rect));
        CGContextStrokePath(ctx);
    }

    [super drawRect:rect];
}

Try the following in your view to check the output from each. The first one updates when the view is called a second time. My controller uses the key ShowCreateButton and has the optional parameter _createAction with a default value - you can change this to your key/parameter

@Html.TextBox("_createAction", null, new { Value = (string)ViewBag.ShowCreateButton })
@Html.TextBox("_createAction", ViewBag.ShowCreateButton )
@ViewBag.ShowCreateButton

According to the spec:

The Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.

Content-Length    = "Content-Length" ":" 1*DIGIT

An example is

Content-Length: 3495

Applications SHOULD use this field to indicate the transfer-length of the message-body, unless this is prohibited by the rules in section 4.4.

Any Content-Length greater than or equal to zero is a valid value. Section 4.4 describes how to determine the length of a message-body if a Content-Length is not given.

Note that the meaning of this field is significantly different from the corresponding definition in MIME, where it is an optional field used within the "message/external-body" content-type. In HTTP, it SHOULD be sent whenever the message's length can be determined prior to being transferred, unless this is prohibited by the rules in section 4.4.

Another solutions are assign RangeIndex or range:

df.index = pd.RangeIndex(len(df.index))

df.index = range(len(df.index))

It is faster:

df = pd.DataFrame({'a':[8,7], 'c':[2,4]}, index=[7,8])
df = pd.concat([df]*10000)
print (df.head())

In [298]: %timeit df1 = df.reset_index(drop=True)
The slowest run took 7.26 times longer than the fastest. This could mean that an intermediate result is being cached.
10000 loops, best of 3: 105 µs per loop

In [299]: %timeit df.index = pd.RangeIndex(len(df.index))
The slowest run took 15.05 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 7.84 µs per loop

In [300]: %timeit df.index = range(len(df.index))
The slowest run took 7.10 times longer than the fastest. This could mean that an intermediate result is being cached.
100000 loops, best of 3: 14.2 µs per loop

I use <span style="display: inline-block; width: 2ch;">&#9;</span> for a two characters wide tab.

This happened to me when I ^C in the middle of a git push to GitHub. GitHub did not show that the changes had been made, however.

To fix it, I made a change to my working tree, committed, and then pushed again. It worked perfectly fine.

Normally I use selenium, which is software for testing automation. You can control a browser through a webdriver, so you will not have problems with javascripts and it is usually not very detected if you use the full version. Headless browsers can be more identified.

To Milan Babuškov, IMO, this is exactly what the replacement function should look like :-)

FILE _iob[] = {*stdin, *stdout, *stderr};

extern "C" FILE * __cdecl __iob_func(void)
{
    return _iob;
}

These do not discard the data in the stringstream in gnu c++

    m.str("");
    m.str() = "";
    m.str(std::string());

The following does empty the stringstream for me:

    m.str().clear();

You can also do what the "Service Reference" generated code does

public class ServiceXClient : ClientBase<IServiceX>, IServiceX
{
    public ServiceXClient() { }

    public ServiceXClient(string endpointConfigurationName) :
        base(endpointConfigurationName) { }

    public ServiceXClient(string endpointConfigurationName, string remoteAddress) :
        base(endpointConfigurationName, remoteAddress) { }

    public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :
        base(endpointConfigurationName, remoteAddress) { }

    public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :
        base(binding, remoteAddress) { }

    public bool ServiceXWork(string data, string otherParam)
    {
        return base.Channel.ServiceXWork(data, otherParam);
    }
}

Where IServiceX is your WCF Service Contract

Then your client code:

var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911"));
client.ServiceXWork("data param", "otherParam param");

echo '<p class="paragrah"' . $i . '">'

You can simply use std::bind with a your destroy function.

std::unique_ptr<Bar, std::function<void(Bar*)>> bar(create(), std::bind(&destroy,
    std::placeholders::_1));

But of course you can also use a lambda.

std::unique_ptr<Bar, std::function<void(Bar*)>> ptr(create(), [](Bar* b){ destroy(b);});

$? returns the exit value of the last executed command. echo $? prints that value on console. zero implies a successful execution while non-zero values are mapped to various reason for failure.

Hence when scripting; I tend to use the following syntax

if [ $? -eq 0 ]; then
 # do something
else
 # do something else
fi

The comparison is to be done on equals to 0 or not equals 0.

** Update Based on the comment: Ideally, you should not use the above code block for comparison, refer to @tripleee comments and explanation.

For Python 2 give execfile a try. (See other answers for Python 3)

execfile('file.py')

Example usage:
Let's use "copy con" to quickly create a small script file...

C:\junk>copy con execfile_example.py
a = [9, 42, 888]
b = len(a)
^Z
        1 file(s) copied.

...and then let's load this script like so:

C:\junk>\python27\python
Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> execfile('execfile_example.py')
>>> a
[9, 42, 888]
>>> b
3
>>>

Here's a concise solution:

_.differenceWith(a, b, _.isEqual);

I've used enumeration to handle this problem.

storage = ''
for num, value in enumerate(result, start=0):
    content = value
    if 'A' == content:
        storage = result[num + 1]

I've used num as Index here, when it finds the correct value it adds up one to the current index of actual list. Which allows me to maneuver to the next index.

I hope this helps your purpose.

If the project is maven placed it in src/main/resources, in the package phase it will copy it in ../WEB-INF/classes/hibernate.cfg.xml

The colon in your first example's url is going to cause an error (Bad Request) so you can't do exactly what you are looking for. Other than that, using a DateTime as an action parameter is most definitely possible.

If you are using the default routing, this 3rd portion of your example url is going to pickup the DateTime value as the {id} parameter. So your Action method might look like this:

public ActionResult Index(DateTime? id)
{
    return View();
}

You'll probably want to use a Nullable Datetime as I have, so if this parameter isn't included it won't cause an exception. Of course, if you don't want it to be named "id" then add another route entry replacing {id} with your name of choice.

As long as the text in the url will parse to a valid DateTime value, this is all you have to do. Something like the following works fine and will be picked up in your Action method without any errors:

<%=Html.ActionLink("link", "Index", new { id = DateTime.Now.ToString("dd-MM-yyyy") }) %>

The catch, in this case of course, is that I did not include the time. I'm not sure there are any ways to format a (valid) date string with the time not represented with colons, so if you MUST include the time in the url, you may need to use your own format and parse the result back into a DateTime manually. Say we replace the colon with a "!" in the actionlink: new { id = DateTime.Now.ToString("dd-MM-yyyy HH!mm") }.

Your action method will fail to parse this as a date so the best bet in this case would probably to accept it as a string:

public ActionResult Index(string id)
{
    DateTime myDate;
    if (!string.IsNullOrEmpty(id))
    {
        myDate = DateTime.Parse(id.Replace("!", ":"));
    }
    return View();
}

Edit: As noted in the comments, there are some other solutions arguably better than mine. When I originally wrote this answer I believe I was trying to preserve the essence of the date time format as best possible, but clearly URL encoding it would be a more proper way of handling this. +1 to Vlad's comment.

This should not affect everyone, but one of the semi-hidden reasons of the repository size being large could be Git submodules.

You might have added one or more submodules, but stopped using it at some time, and some files remained in .git/modules directory. To make redundant submodule files gone away, see this question.

However, just like the main repository, the other way is to navigate to the submodule directory in .git/modules, and do a, for example, git gc --aggressive --prune.

These should have a good impact in the repository size, but as long as you use Git submodules, e.g. especially with large libraries, your repository size should not change drastically.

Change:

CONVERT(varchar(3), DATEPART(MONTH, S0.OrderDateTime) AS OrderMonth

To:

CONVERT(varchar(3), DATENAME(MONTH, S0.OrderDateTime)) AS OrderMonth

Tried to add this as a comment to Rob Prouse's posting, but the lack of formatting made it unintelligible.

In Visual Studio 2010, the "Tools | Options | Projects and Solutions | VC++ Directories" dialog reports that "VC++ Directories editing in Tools > Options has been deprecated", proposing that you use the rather counter-intuitive Property Manager.

If you really, really want to update the default $(IncludePath), you have to hack the appropriate entry in one of the XML files:

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\Win32\PlatformToolsets\v100\Microsoft.Cpp.Win32.v100.props

or

\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Platforms\x64\PlatformToolsets\v100\Microsoft.Cpp.X64.v100.props

(Probably not Microsoft-recommended.)

You probably want this:

string[,] Tablero = new string[3,3];

This will create you a matrix-like array where all rows have the same length.

The array in your sample is a so-called jagged array, i.e. an array of arrays where the elements can be of different size. A jagged array would have to be created in a different way:

string[][] Tablero = new string[3][];
for (int i = 0; i < Tablero.GetLength(0); i++)
{
    Tablero[i] = new string[3];
}

You can also use initializers to fill the array elements with data:

string[,] Tablero = new string[,]
{
    {"1.1","1.2", "1.3"},
    {"2.1","2.2", "2.3"},
    {"3.1", "3.2", "3.3"}
};

And in case of a jagged array:

string[][] Tablero = new string[][]
{
    new string[] {"1.1","1.2", "1.3"},
    new string[] {"2.1","2.2", "2.3"},
    new string[] {"3.1", "3.2", "3.3"}
};

If you have properly structured your tables so that each contains relatively unique values, then the less intensive way to do this would be to do 3 separate insert-into statements, 1 for each table, with the join-filter in place for each insert -

INSERT INTO SkusBought...

SELECT t1.customer, t1.SKU, t1.TypeDesc
FROM transactiondatatransit AS T1
LEFT OUTER JOIN topThreetransit AS T2
ON t1.customer = t2.customernum
WHERE T2.customernum IS NOT NULL

Repeat this for the other two tables - copy/paste is a fine method, simply change the FROM table name. ** IF you are trying to prevent duplicated entries in your SkusBought table you can add the following join code in each section prior to the WHERE clause.

LEFT OUTER JOIN SkusBought AS T3
ON  t1.customer = t3.customer
AND t1.sku = t3.sku

-and then the last line of WHERE clause-

AND t3.customer IS NULL

Your initial code is using a number of sub-queries, and the UNION statement can be expensive as it will first create its own temporary table to populate the data from the three separate sources before inserting into the table you want ALONG with running another sub-query to filter results.

list(cursor) works because a cursor is an iterable; you can also use cursor in a loop:

for row in cursor:
    # ...

A good database adapter implementation will fetch rows in batches from the server, saving on the memory footprint required as it will not need to hold the full result set in memory. cursor.fetchall() has to return the full list instead.

There is little point in using list(cursor) over cursor.fetchall(); the end effect is then indeed the same, but you wasted an opportunity to stream results instead.

Another option is to map is as a Map of composite elements in the ConfPath table.

This mapping would benefit from an index on (ConfPathID,levelStation) though.

public class ConfPath {
    private Map<Long,Time> timeForLevelStation = new HashMap<Long,Time>();

    public Time getTime(long levelStation) {
        return timeForLevelStation.get(levelStation);
    }

    public void putTime(long levelStation, Time newValue) {
        timeForLevelStation.put(levelStation, newValue);
    }
}

public class Time {
    String src;
    String dst;
    long distance;
    long price;

    public long getDistance() {
        return distance;
    }

    public void setDistance(long distance) {
        this.distance = distance;
    }

    public String getDst() {
        return dst;
    }

    public void setDst(String dst) {
        this.dst = dst;
    }

    public long getPrice() {
        return price;
    }

    public void setPrice(long price) {
        this.price = price;
    }

    public String getSrc() {
        return src;
    }

    public void setSrc(String src) {
        this.src = src;
    }
}

Mapping:

<class name="ConfPath" table="ConfPath">
    <id column="ID" name="id">
        <generator class="native"/>
    </id>
    <map cascade="all-delete-orphan" name="values" table="example"
            lazy="extra">
        <key column="ConfPathID"/>
        <map-key type="long" column="levelStation"/>
        <composite-element class="Time">
            <property name="src" column="src" type="string" length="100"/>
            <property name="dst" column="dst" type="string" length="100"/>
            <property name="distance" column="distance"/>
            <property name="price" column="price"/>
        </composite-element>
    </map>
</class>

Putting together answers from Peter Bailey and Cmyker you get something like:

<?php
foreach ($_SERVER as $key => $value) {
    if (strpos($key, 'HTTP_') === 0) {
        $chunks = explode('_', $key);
        $header = '';
        for ($i = 1; $y = sizeof($chunks) - 1, $i < $y; $i++) {
            $header .= ucfirst(strtolower($chunks[$i])).'-';
        }
        $header .= ucfirst(strtolower($chunks[$i])).': '.$value;
        echo $header."\n";
    }
}
$body = file_get_contents('php://input');
if ($body != '') {
  print("\n$body\n\n");
}
?>

which works with the php -S built-in webserver, which is quite a handy feature of PHP.

Well you just need to use document.getElementById('hello').setAttribute('class', 'someclass');.

Also innerHTML can lead to unexpected results! Consider the following;

var myParag = document.createElement('p');

if(under certain age)
{
    myParag.text="Good Bye";
    createCookie('age', 'not13', 0);
    return false;
{
else
{
    myParag.text="Hello";
    return true;
}

document.getElementById('hello').appendChild(myParag);

Here's from my own code:
Window.setTimeout executes only when browser is idle.
So calling the function recursively (42 times) will take 100ms if there is no activity in the browser and much more if the browser is busy doing something else.

    ExpectedCondition<Boolean> javascriptDone = new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver d) {
            try{//window.setTimeout executes only when browser is idle,
                //introduces needed wait time when javascript is running in browser
                return  ((Boolean) ((JavascriptExecutor) d).executeAsyncScript( 

                        " var callback =arguments[arguments.length - 1]; " +
                        " var count=42; " +
                        " setTimeout( collect, 0);" +
                        " function collect() { " +
                            " if(count-->0) { "+
                                " setTimeout( collect, 0); " +
                            " } "+
                            " else {callback(" +
                            "    true" +                            
                            " );}"+                             
                        " } "
                    ));
            }catch (Exception e) {
                return Boolean.FALSE;
            }
        }
    };
    WebDriverWait w = new WebDriverWait(driver,timeOut);  
    w.until(javascriptDone);
    w=null;

As a bonus the counter can be reset on document.readyState or on jQuery Ajax calls or if any jQuery animations are running (only if your app uses jQuery for ajax calls...)
...

" function collect() { " +
                            " if(!((typeof jQuery === 'undefined') || ((jQuery.active === 0) && ($(\":animated\").length === 0))) && (document.readyState === 'complete')){" +
                            "    count=42;" +
                            "    setTimeout( collect, 0); " +
                            " }" +
                            " else if(count-->0) { "+
                                " setTimeout( collect, 0); " +
                            " } "+ 

...

EDIT: I notice executeAsyncScript doesn't work well if a new page loads and the test might stop responding indefinetly, better to use this on instead.

public static ExpectedCondition<Boolean> documentNotActive(final int counter){ 
    return new ExpectedCondition<Boolean>() {
        boolean resetCount=true;
        @Override

            if(resetCount){

                        "   }\r\n" + 
                        "   window.mssJSDelay();");
                resetCount=false;
            }

            boolean ready=false;
            try{

Using num_holes=None as the default is fine if you are going to have just __init__.

If you want multiple, independent "constructors", you can provide these as class methods. These are usually called factory methods. In this case you could have the default for num_holes be 0.

class Cheese(object):
    def __init__(self, num_holes=0):
        "defaults to a solid cheese"
        self.number_of_holes = num_holes

    @classmethod
    def random(cls):
        return cls(randint(0, 100))

    @classmethod
    def slightly_holey(cls):
        return cls(randint(0, 33))

    @classmethod
    def very_holey(cls):
        return cls(randint(66, 100))

Now create object like this:

gouda = Cheese()
emmentaler = Cheese.random()
leerdammer = Cheese.slightly_holey()

My personal preference is to build rpm packages for CentOS when installing non-standard software and replacing distributed components. For this I recommend that you use Mock to create a clean build environment.

The procedure is:

1. Obtain the source RPMS or a suitable SPEC file and pristine source tarball. In this case one may find source RPM packages for git2X for CentOS-6 at: http://dl.iuscommunity.org/pub/ius/archive/CentOS/6/SRPMS/. Packages for other CentOS releases are also available.

2. Install the necessary support software:

   yum install epel-release  # you need this for mock
   yum install rpm-build
   yum install redhat-rpm-config
   yum install rpmdevtools
   yum install mock
   

3. Add a rpm build user account (do not build as root or as a real user - security issues will come back to bite you).

   sudo adduser builder --home-dir /home/builder \
   --create-home --user-group --groups mock \
   --shell /bin/bash --comment "rpm package builder"
   

4. Next we need a build environment.

   su -l builder
   rpmdev-setuptree
   

   This produces the following directory structure:

   ~
   +-- rpmbuild
       +-- BUILD
       +-- RPMS
       +-- SOURCES
       +-- SPECS
       +-- SRPMS
   

5. We are using a prepared SRPMS so the SOURCES tarballs can be ignored for this case and we can go direct to SRPMS.

   wget http://dl.iuscommunity.org/pub/ius/archive/CentOS/6/SRPMS/git2u-2.5.3-1.ius.centos6.src.rpm \
   -O ~/rpmbuild/SRPMS/git2u-2.5.3-1.ius.centos6.src.rpm
   

6. Configure mock (as root)

   cd /etc/mock
   rm default.cfg
   ln -s epel-6-x86_64.cfg default.cfg
   vim default.cfg
   

   Disable the beta repos. Enable the base and update repos.

7. Initialize the build tree (/var/lib/mock is default)

   mock --init
   

8. If we were building from SOURCES then this is where we would employ the SPEC file and use mock --buildsrpm . . .. But in this case we go directly to the binary build step:

   mock --no-clean --rebuild ~/rpmbuild/SRPMS/git2u-2.5.3-1.ius.centos6.src.rpm
   

   This will resolve the build dependencies and download them (about 95 or so packages) into the clean build root. It will then extract the sources and build the binary from the provided SRPM and leave it in /var/lib/mock/epel-6-x86_64/result; or in whatever custom build root location and architecture you provided. It will take a long time. There is a lot to this package; particularly documentation.

9. If all goes well then you should end up with a suit of RPM packages suitable for installation in place of the distro version. This is what I ended up with:

   ll /var/lib/mock/epel-6-x86_64/result
   total 34996

10. Install using yum or rpm.

    You will require git2u-2.5.3-1.ius.el6.x86_64.rpm at a minimum and such additional support packages as it requires (perl-Git2u-2.5.3-1.ius.el6.noarch.rpm) or you desire.

    This build has a cyclic dependency: git2u-2.5.3-1.ius.el6.x86_64.rpm depends upon perl-Git2u-2.5.3-1.ius.el6.noarch.rpm and perl-Git2u-2.5.3-1.ius.el6.noarch.rpm depends upon git2u-2.5.3-1.ius.el6.x86_64.rpm. A straight install with rpm will thus fail.

    There are two ways of dealing with it:

    • Install both at the same time via yum:

      yum localinstall \
        git2u-2.5.3-1.ius.el6.x86_64.rpm \
        perl-Git2u-2.5.3-1.ius.el6.noarch.rpm`
      

    • Setup a local yum repo.

      I am including my LocalFile.repo file below as it contains instructions on how to do this and provides the necessary repo file at the same time.

cat /etc/yum.repos.d/LocalFile.repo
# LocalFile.repo
#
#  This repo is used with a local filesystem repo.
#
# To use this repo place the rpm package in /root/RPMS/yum.repo/Packages.
# Then run: createrepo --database --update /root/RPMS/yum.repo.
#
# To use:
#  yum --enablerepo=localfile [command]
#  
# or to use only ONLY this repo, do this:
#
#  yum --disablerepo=\* --enablerepo=localfile [command]

[localfile]
baseurl=file:///root/RPMS/yum.repo
name=CentOS-$releasever - Local Filesystem repo

# Before persistently enabling this repo see the priority note below.
enabled=0
gpgcheck=0

# When this repo is enabled all packages in repos with priority>5
# will not be updated even when they have a more recent version.
# Be careful with this.
priority=5

You also may be required to manually pre-install additional dependency packages such as perl-TermReadKey available from the usual repositories.

you can use decoration like this :

   Container(
                    width: 60,
                    height: 60,
                    child: Icon(CustomIcons.option, size: 20,),
                    decoration: BoxDecoration(
                        shape: BoxShape.circle,
                        color: Color(0xFFe0f2f1)),
                  )

Now you have circle shape and Icon on it.

how do i append a number into the drug_dictionary?

Do you wish to add "a number" or a set of values?

I use dictionaries to build associative arrays and lookup tables quite a bit.

Since python is so good at handling strings, I often use a string and add the values into a dict as a comma separated string

drug_dictionary = {} 

drug_dictionary={'MORPHINE':'',
         'OXYCODONE':'',
         'OXYMORPHONE':'',
         'METHADONE':'',
         'BUPRENORPHINE':'',
         'HYDROMORPHONE':'',
         'CODEINE':'',
         'HYDROCODONE':''}


drug_to_update = 'MORPHINE'

try: 
   oldvalue = drug_dictionary[drug_to_update] 
except: 
   oldvalue = ''

# to increment a value

   try: 
      newval = int(oldval) 
      newval += 1
   except: 
      newval = 1 


   drug_dictionary[drug_to_update] = "%s" % newval

# to append a value  

   try: 
      newval = int(oldval) 
      newval += 1
   except: 
      newval = 1 


   drug_dictionary[drug_to_update] = "%s,%s" % (oldval,newval) 

The Append method allows for storing a list of values but leaves you will a trailing comma

which you can remove with

drug_dictionary[drug_to_update][:-1]

the result of the appending the values as a string means that you can append lists of values as you need too and

print "'%s':'%s'" % ( drug_to_update, drug_dictionary[drug_to_update]) 

can return

'MORPHINE':'10,5,7,42,12,'

As of Room 1.1.0 you can use clearAllTables() which:

Deletes all rows from all the tables that are registered to this database as entities().

You might want to take a look at Maven (http://maven.apache.org). You can use it either as the main build process for your application, or just to perform certain tasks through the Edit Configurations dialog. The process of creating a JAR of a module within Maven is fairly trivial, if you want it to include all the dependencies in a self-executable JAR that is trivial as well.

If you've never used Maven before then you want to read Better Builds With Maven.

On *nix, you can use comm. The answer to the question is:

comm -1 -2 file1.sorted file2.sorted 
# where file1 and file2 are sorted and piped into *.sorted

Here's the full usage of comm:

comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2. 

Also note that it is important to sort the files before using comm, as mentioned in the man pages.

If you're writing C++, I can't recommend using the Boost libraries strongly enough.

The latest version (1.55) includes a new Predef library which covers exactly what you're looking for, along with dozens of other platform and architecture recognition macros.

#include <boost/predef.h>

// ...

#if BOOST_OS_WINDOWS

#elif BOOST_OS_LINUX

#elif BOOST_OS_MACOS

#endif

To check if field is NULL use IS NULL, IS NOT NULL operators.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. I've read it will be fixed in the next release of Java, but it's not out yet. Supposedly, it was fixed in 1.7.0_60b01, but I can't find where to download it and 1.7.0_60b02 re-introduces the bug.

I managed to get around the problem by reverting back to JDK 1.7.0_25. Probably not the solution you wanted, but it's the only way I've been able to get it working. Don't forget add JDK 1.7.0_25 in Eclipse after installing the JDK.

Please DO NOT REPLY directly to this email but go to StackOverflow: Class JavaLaunchHelper is implemented in both. One of the two will be used. Which one is undefined

Since this is only an issue in IE, to resolve this, I'm first detecting if the browser is IE and if so, use a jquery click event. I put this code into a global file so it's fixed throughout the site.

if (navigator.appName === 'Microsoft Internet Explorer')
{
    $('a input.button').click(function()
    {
        window.location = $(this).closest('a').attr('href');
    });
}

This way we only have the overhead of assigning click events to linked input buttons for IE. note: The above code is inside a document ready function to make sure the page is completely loaded before assigning click events.

I also assigned class names to my input buttons to save some overhead when using IE so I can search for

$('a input.button')

instead of

$('a input[type=button]')

.

<a href="some_link"><input type="button" class="button" value="some value" /></a>

On top of all that, I'm also utilizing CSS to make the buttons look clickable when your mouse hovers over it:

input.button {cursor: pointer}

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

http://www.rgagnon.com/javadetails/java-0542.html

Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

Byte array of unknown length in java

Edit: The following could be used to fingerprint small files before and after transfer (use SHA if you feel it's necessary):

public static String md5String(File file) {
    try {
        InputStream fin = new FileInputStream(file);
        java.security.MessageDigest md5er = MessageDigest.getInstance("MD5");
        byte[] buffer = new byte[1024];
        int read;
        do {
            read = fin.read(buffer);
            if (read > 0) {
                md5er.update(buffer, 0, read);
            }
        } while (read != -1);

Its not quite fine to downgrade everytime, you may need to make following changes as shown below:

Tensorflow

import tensorflow as tf

#Keras
from tensorflow.keras.models import Sequential, Model, load_model, save_model
from tensorflow.keras.callbacks import ModelCheckpoint
from tensorflow.keras.layers import Dense, Activation, Dropout, Input, Masking, TimeDistributed, LSTM, Conv1D, Embedding
from tensorflow.keras.layers import GRU, Bidirectional, BatchNormalization, Reshape
from tensorflow.keras.optimizers import Adam

from tensorflow.keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding
from tensorflow.keras import optimizers
from tensorflow.keras.callbacks import ModelCheckpoint

The point is that instead of using

from keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding

you need to add

from tensorflow.keras.layers import Reshape, Dropout, Dense,Multiply, Dot, Concatenate,Embedding

Try this:

#myelement {
  background-position: 100% 50%;
  margin-right: 5px;
}

Note though that the code above will move the whole element (not the background image only) 5px from the right. This might be ok for your case.

Url.Action("Evil", model)

Just Add "JsonRequestBehavior.AllowGet" on your Json object.

I think the best thing to do, if you're really concerned about the efficiency of concatenating all of these files, is to copy them all into the same bytes buffer.

buf := bytes.NewBuffer(nil)
for _, filename := range filenames {
  f, _ := os.Open(filename) // Error handling elided for brevity.
  io.Copy(buf, f)           // Error handling elided for brevity.
  f.Close()
}
s := string(buf.Bytes())

This opens each file, copies its contents into buf, then closes the file. Depending on your situation you may not actually need to convert it, the last line is just to show that buf.Bytes() has the data you're looking for.

I found this page which tells you how to import a PFX to JKS (Java Key Store):

keytool -importkeystore -srckeystore PFX_P12_FILE_NAME -srcstoretype pkcs12 -srcstorepass PFX_P12_FILE -srcalias SOURCE_ALIAS -destkeystore KEYSTORE_FILE -deststoretype jks -deststorepass PASSWORD -destalias ALIAS_NAME

This does not directly answer the question, but may help future visitors.

If you want to have a variable always be the current state of the checkbox (rather than having to keep checking its state), you can modify the onchange event to set that variable.

This can be done in the HTML:

<input class='messageCheckbox' type='checkbox' onchange='some_var=this.checked;'>

or with JavaScript:

cb = document.getElementsByClassName('messageCheckbox')[0]
cb.addEventListener('change', function(){some_var = this.checked})

change the MaxClients directive. it is now on 256.

just came across while browsing, might help you javascript-getting-and-setting-caret-position-in-textarea. You can use it for textbox also.

Just to add to the previous comment, the documentation for the command line tool for updating the Tomcat service settings (if Tomcat is running as a service on Windows) is here. This tool updates the registry with the proper settings. So if you wanted to update the max memory setting for the Tomcat service you could run this (from the tomcat/bin directory), assuming the default service name of Tomcat5:

tomcat5 //US//Tomcat5 --JvmMx=512

For me was a declaration incomplete. For example:

var isInverted: Bool

Instead the correct way:

var isInverted: Bool = false

[root@pentest3r ~]# (find / -xdev -size +1024M) | (while read a ; do aa=$(du -sh $a | cut -d "." -f1 ); o=$(( $o+$aa )); done; echo "$o";)

Use

g++

space followed by the program name. e.g:

g++ prog.cpp

if the filename was "prog.cpp" in this case. if you want to run the program write:

./prog

so i used

"prog"

because it was my filename.

paste0("data_",seq(1,3,1)) 
# makes multiple data.frame names with sequential number
rm(list=paste0("data_",seq(1,3,1))
# above code removes data_1~data_3

for me anyways, it helps to see it used. just made this using the "re" example:

var analyte_data = 'sample-'+sample_id;
var storage_keys = $.jStorage.index();
var re = new RegExp( analyte_data,'g');  
for(i=0;i<storage_keys.length;i++) { 
    if(storage_keys[i].match(re)) {
        console.log(storage_keys[i]);
        var partnum = storage_keys[i].split('-')[2];
    }
}

Another useful thing to do with numpy.histogram is to plot the output as the x and y coordinates on a linegraph. For example:

arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()

This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.

If you don't want to use WMI, I can suggest systeminfo.exe. But, there may be a better way to do that.

IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm.

This event handler is called when new instance of the UserForm is created. In this even handler u can initialize the private members of UserForm1 class.

Example:

Standard module code:

Option Explicit

Public Sub Main()
  Dim myUserForm As UserForm1

  Set myUserForm = New UserForm1
  myUserForm.Show

End Sub

User form code:

Option Explicit

Private m_initializationDate As Date

Private Sub UserForm_Initialize()
  m_initializationDate = VBA.DateTime.Date
  MsgBox "Hi from UserForm_Initialize event handler.", vbInformation
End Sub

You would need to say which version of Ant and which JVM version.

You can run ant -v to see which settings Ant is using as per the doc

Ant 1.8* requires JDK 1.4 or higher.

The 'Unsupported major.minor version 51.0' means somewhere code was compiled for a version of the JDK, and that you are trying to run those classes under an older version of the JDK. (see here)

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.

rm -rf was much more performant than FileUtils.deleteDirectory.

After extensive benchmarking, we found that using rm -rf was multiple times faster than using FileUtils.deleteDirectory.

Of course, if you have a small or simple directory, it won't matter but in our case we had multiple gigabytes and deeply nested sub directories where it would take over 10 minutes with FileUtils.deleteDirectory and only 1 minute with rm -rf.

Here's our rough Java implementation to do that:

// Delete directory given and all subdirectories and files (i.e. recursively).
//
static public boolean deleteDirectory( File file ) throws IOException, InterruptedException {

    if ( file.exists() ) {

        String deleteCommand = "rm -rf " + file.getAbsolutePath();
        Runtime runtime = Runtime.getRuntime();

        Process process = runtime.exec( deleteCommand );
        process.waitFor();

        return true;
    }

    return false;

}

Worth trying if you're dealing with large or complex directories.

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close


End Sub

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

On newer versions of Docker you can run docker exec [container_name] which runs a shell inside your container

So to get a list of all the files in a container just run docker exec [container_name] ls

Worksheets("Sheet1").Range("A1:A5").Copy
Worksheets("Sheet2").Range("A1").PasteSpecial Transpose:=True

Your container probably haven't installed it out of the box.

Run apt-get install vim in the terminal and you should be ready to go.

JavaScript Date constructor accepts number of milliseconds since Unix epoch (1 January 1970 00:00:00 UTC). Here’s C# extension method that converts .Net DateTime object to JavaScript date:

public static class DateTimeJavaScript
{
   private static readonly long DatetimeMinTimeTicks =
      (new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).Ticks;

   public static long ToJavaScriptMilliseconds(this DateTime dt)
   {
      return (long)((dt.ToUniversalTime().Ticks - DatetimeMinTimeTicks) / 10000);
   }
}

JavaScript Usage:

var dt = new Date(<%= DateTime.Today.ToJavaScriptMilliseconds() %>);
alert(dt);

The gitlog-to-changelog script comes in handy to generate a GNU-style ChangeLog.

As shown by gitlog-to-changelog --help, you may select the commits used to generate a ChangeLog file using either the option --since:

gitlog-to-changelog --since=2008-01-01 > ChangeLog

or by passing additional arguments after --, which will be passed to git-log (called internally by gitlog-to-changelog):

gitlog-to-changelog -- -n 5 foo > last-5-commits-to-branch-foo

For instance, I am using the following rule in the top-level Makefile.am of one of my projects:

.PHONY: update-ChangeLog
update-ChangeLog:
    if test -d $(srcdir)/.git; then                         \
       $(srcdir)/build-aux/gitlog-to-changelog              \
          --format='%s%n%n%b%n' --no-cluster                \
          --strip-tab --strip-cherry-pick                   \
          -- $$(cat $(srcdir)/.last-cl-gen)..               \
        >ChangeLog.tmp                                      \
      && git rev-list -n 1 HEAD >.last-cl-gen.tmp           \
      && (echo; cat $(srcdir)/ChangeLog) >>ChangeLog.tmp    \
      && mv -f ChangeLog.tmp $(srcdir)/ChangeLog            \
      && mv -f .last-cl-gen.tmp $(srcdir)/.last-cl-gen      \
      && rm -f ChangeLog.tmp;                               \
    fi

EXTRA_DIST += .last-cl-gen

This rule is used at release time to update ChangeLog with the latest not-yet-recorded commit messages. The file .last-cl-gen contains the SHA1 identifier of the latest commit recorded in ChangeLog and is stored in the Git repository. ChangeLog is also recorded in the repository, so that it can be edited (e.g. to correct typos) without altering the commit messages.

Based on the answer from #squiguy, to get a true timestamp I would type cast it from float.

>>> import time
>>> ts = int(time.time())
>>> print(ts)
1389177318

At least that's the concept.

You can add and remove classes with jQuery like so:

$(".first").addClass("second")
// remove a class
$(".first").removeClass("second")

By the way you can set multiple classes in your markup right away separated with a whitespace

<div class="second first"></div>

This is still an issue in VS Community 2015 and 2017 when building either console or windows apps. If the project is created with precompiled headers, the precompiled headers are apparently loaded before any of the #includes, so even if the #define _USE_MATH_DEFINES is the first line, it won't compile. #including math.h instead of cmath does not make a difference.

The only solutions I can find are either to start from an empty project (for simple console or embedded system apps) or to add /Y- to the command line arguments, which turns off the loading of precompiled headers.

For information on disabling precompiled headers, see for example https://msdn.microsoft.com/en-us/library/1hy7a92h.aspx

It would be nice if MS would change/fix this. I teach introductory programming courses at a large university, and explaining this to newbies never sinks in until they've made the mistake and struggled with it for an afternoon or so.

You should have used:

a:hover {
    text-decoration: underline;
}

hover is a pseudo class in CSS. No need to assign a class.

The correct answer on how to take the extension available in a filename in linux is:

${filename##*\.} 

Example of printing all file extensions in a directory

for fname in $(find . -maxdepth 1 -type f) # only regular file in the current dir
    do  echo ${fname##*\.} #print extensions 
done

I got this error on Azure Git, and this solves the problem:

git fetch
git pull
git push --no-verify

Simply try to multiply by one as following:

"00123" * 1;              // Get as number
"00123" * 1 + "";       // Get as string

The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!

If you want to hide them anyway: error_reporting(0);

I guess this is also possible like this?

var movies = _db.Movies.TakeWhile(p => p.Genres.Any(x => listOfGenres.Contains(x));

Is "TakeWhile" worse than "Where" in sense of performance or clarity?

It should be as simple as using a list of receiving variables:

scanf("%i %i %i", &var1, &var2, &var3);

A little more elaborate example.

I've named webapp_dir and website_dir on purpose. If you have matching names and folders you can use the root directive.

This setup works and is tested with Docker.

NB!!! Be careful with the slashes. Put them exactly as in the example.

According to the documentation you can decode JPEG/PNG images.

It should be something like this:

import tensorflow as tf

filenames = ['/image_dir/img.jpg']
filename_queue = tf.train.string_input_producer(filenames)

reader = tf.WholeFileReader()
key, value = reader.read(filename_queue)

images = tf.image.decode_jpeg(value, channels=3)

You can find a bit more info here

>>> ord('a')
97
>>> chr(97)
'a'

edgesForExtendedLayout does the trick for iOS 7. However, if you build the app across iOS 7 SDK and deploy it in iOS 6, the navigation bar appears translucent and the views go beneath it. So, to fix it for both iOS 7 as well as for iOS 6 do this:

self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
    self.edgesForExtendedLayout = UIRectEdgeNone;   // iOS 7 specific

You can resave the image and literally find the src file of your project and add it to that when you save. For me I had to go to netbeans and found my project and when that comes up it had 3 files src was the last. Don't click on any of them just save your pic there. That should work. Now resizing it may be a different issue and one I'm working on now lol

you can intersect types:

type TypeA = {
    nameA: string;
};
type TypeB = {
    nameB: string;
};
export type TypeC = TypeA & TypeB;

somewhere in you code you can now do:

const some: TypeC = {
    nameB: 'B',
    nameA: 'A',
};

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.

Using inline styles:

<input type="text" style="text-align: right"/>

or, put it in a style sheet, like so:

<style>
   .rightJustified {
        text-align: right;
    }
</style>

and reference the class:

<input type="text" class="rightJustified"/>

You said your website has Flash, then, as another option, you can get operation system's language with flash.system.Capabilities.language— see How to determine OS language within browser to guess an operation system locale.

You can install this plugin in Firefox: https://addons.mozilla.org/en-US/firefox/addon/cliget/?src=cb-dl-toprated Start downloading what you want and click on the plugin. It gives you the whole command either for wget or curl to download the file on the serer. Very easy!

Think of TCP as a dedicated scheduled UPS/FedEx pickup/dropoff of packages between two locations, while UDP is the equivalent of throwing a postcard in a mailbox.

UPS/FedEx will do their damndest to make sure that the package you mail off gets there, and get it there on time. With the post card, you're lucky if it arrives at all, and it may arrive out of order or late (how many times have you gotten a postcard from someone AFTER they've gotten home from the vacation?)

TCP is as close to a guaranteed delivery protocol as you can get, while UDP is just "best effort".

I've had a similar issue with User registration today and I was getting a

SQLSTATE[HY000]: General error: 1364 Field 'password' doesn't have a default value (SQL: insert into users

I fixed it by adding password to my protected $fillable array and it worked

protected $fillable = [
  'name',
  'email',
  'password',
];

I hope this helps.

https://developers.google.com/android/ you need to generate configuration file which gives you access to all the services and APIs you registered for in developer console and place it in your root directory

here's an idea... just pull down one full page of results from each of the three and then throw out the 20 least useful ones... this eliminates the large querysets and that way you only sacrifice a little performance instead of a lot

In order to make that working I had to set:

compile ("com.android.support:support-v4:22.2.0")
compile ("com.android.support:appcompat-v7:22.2.0")
compile ("com.android.support:support-annotations:22.2.0")
compile ("com.android.support:recyclerview-v7:22.2.0")
compile ("com.android.support:design:22.2.0")

compile ("com.android.support:design:22.2.0")

Documentation states something different (docs):

com.android.support:support-design:22.0.0

You can do this using del and the /S flag (to tell it to recurse all files from all subdirectories):

del /S C:\Path\to\directory\*

The RD command can also be used. Recursively delete quietly without a prompt:

@RD /S /Q %VAR_PATH%

Rmdir (rd)

Try this: getActivity().runOnUiThread(new Runnable...

It's because:

1) the implicit this in your call to runOnUiThread is referring to AsyncTask, not your fragment.

2) Fragment doesn't have runOnUiThread.

However, Activity does.

Note that Activity just executes the Runnable if you're already on the main thread, otherwise it uses a Handler. You can implement a Handler in your fragment if you don't want to worry about the context of this, it's actually very easy:

// A class instance
private Handler mHandler = new Handler(Looper.getMainLooper());

// anywhere else in your code
mHandler.post(<your runnable>);
// ^ this will always be run on the next run loop on the main thread.

EDIT: @rciovati is right, you are in onPostExecute, that's already on the main thread.

You don't fetch a branch, you fetch an entire remote:

git fetch origin
git merge origin/an-other-branch

For the complete list of attributes, the short answer is: no. The problem is that the attributes are actually defined as the arguments accepted by the getattr built-in function. As the user can reimplement __getattr__, suddenly allowing any kind of attribute, there is no possible generic way to generate that list. The dir function returns the keys in the __dict__ attribute, i.e. all the attributes accessible if the __getattr__ method is not reimplemented.

For the second question, it does not really make sense. Actually, methods are callable attributes, nothing more. You could though filter callable attributes, and, using the inspect module determine the class methods, methods or functions.

For combining HTML and PHP you can use .phtml files.

A few things happening here:

1. I assume you required fs/http, and set the dir variable :)
2. google.com redirects to www.google.com, so you're saving the redirect response's body, not the image
3. the response is streamed. that means the 'data' event fires many times, not once. you have to save and join all the chunks together to get the full response body
4. since you're getting binary data, you have to set the encoding accordingly on response and writeFile (default is utf8)

This should work:

var http = require('http')
  , fs = require('fs')
  , options

options = {
    host: 'www.google.com'
  , port: 80
  , path: '/images/logos/ps_logo2.png'
}

var request = http.get(options, function(res){
    var imagedata = ''
    res.setEncoding('binary')

    res.on('data', function(chunk){
        imagedata += chunk
    })

    res.on('end', function(){
        fs.writeFile('logo.png', imagedata, 'binary', function(err){
            if (err) throw err
            console.log('File saved.')
        })
    })

})

Calendar.setTime()

It's often useful to look at the signature and description of API methods, not just their name :) - Even in the Java standard API, names can sometimes be misleading.

dates_dict[key] = dates_dict.get(key, []).append(date) sets dates_dict[key] to None as list.append returns None.

In [5]: l = [1,2,3]

In [6]: var = l.append(3)

In [7]: print var
None

You should use collections.defaultdict

import collections
dates_dict = collections.defaultdict(list)

you can use this to get the data of the last 30 days based on a column.

WHERE DATEDIFF(dateColumn,CURRENT_TIMESTAMP) BETWEEN 0 AND 30

In my case it allows me to apply a CSS stylesheet without worrying about copying associated images, since they're already embedded inside.

The value of the accept attribute is, as per HTML5 LC, a comma-separated list of items, each of which is a specific media type like image/gif, or a notation like image/* that refers to all image types, or a filename extension like .gif. IE 10+ and Chrome support all of these, whereas Firefox does not support the extensions. Thus, the safest way is to use media types and notations like image/*, in this case

<input type="file" name="foo" accept=
"application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint,
text/plain, application/pdf, image/*">

if I understand the intents correctly. Beware that browsers might not recognize the media type names exactly as specified in the authoritative registry, so some testing is needed.

I had this error message:

Error: Can't open display: localhost:13.0

This fixed it for me:

export DISPLAY="localhost:10.0"

You can use this too:

export DISPLAY="127.0.0.1:10.0"

Use:

s.erase(std::remove_if(s.begin(), s.end(), my_predicate), s.end());

bool my_predicate(char c)
{
 return !(isalpha(c) || c=='_' || c==' '); // depending on you definition of special characters
}

And you'll get a clean string s.

erase() will strip it of all the special characters and is highly customisable with the my_predicate() function.

This worked for me.

map_canvas {position: absolute; top: 0; right: 0; bottom: 0; left: 0;}

I see two things missing from the other answers:

• canvas.toBlob (when available) is more performant than canvas.toDataURL, and also async.
• the file -> image -> canvas -> file conversion loses EXIF data; in particular, data about image rotation commonly set by modern phones/tablets.

The following script deals with both points:

// From https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob, needed for Safari:
if (!HTMLCanvasElement.prototype.toBlob) {
    Object.defineProperty(HTMLCanvasElement.prototype, 'toBlob', {
        value: function(callback, type, quality) {

            var binStr = atob(this.toDataURL(type, quality).split(',')[1]),
                len = binStr.length,
                arr = new Uint8Array(len);

            for (var i = 0; i < len; i++) {
                arr[i] = binStr.charCodeAt(i);
            }

            callback(new Blob([arr], {type: type || 'image/png'}));
        }
    });
}

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

The terms "interpreted language" or "compiled language" don't make sense, because any programming language can be interpreted and/or compiled.

As for the existing implementations of Java, most involve a compilation step to bytecode, so they involve compilation. The runtime also can load bytecode dynamically, so some form of a bytecode interpreter is always needed. That interpreter may or may not in turn use compilation to native code internally.

These days partial just-in-time compilation is used for many languages which were once considered "interpreted", for example JavaScript.

Try not closing the connection before you send data to your database. Remove client.close(); from your code and it'll work fine.
