I like the explanation From EdX (Microsoft: DEV210x Introduction to C++) for a similar problem:

"The enum represents the literal values of days as integers. Referring to the numeric types table, you see that an int takes 4 bytes of memory. 7 days x 4 bytes each would require 28 bytes of memory if the entire enum were stored but the compiler only uses a single element of the enum, therefore the size in memory is actually 4 bytes."

It is because one of the DBs the column was created with " which makes its name case-sensitive.

Oracle Table Column Name : GoodRec Hive cannot recognize case sensitivity : ERROR thrown was - Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "GOODREC": invalid identifier

Solution : Rename Oracle column name to all caps.

If you have headers in the markdown files, you can directly link them in the file.

Markdown Header -

## The Header

this will generate an implicit id #the-header (replace internal spaces with hyphens and make lowercase).

To navigate to this id, you can create the link like this:

[Link to Header](#the-header)

This is equivalent to:

<a href="#the-header">Link to Header</a>

Please note the reference's name is a lower-case #header.

Just use

filter_input(INPUT_METHOD_NAME, 'var_name') instead of $_INPUT_METHOD_NAME['var_name'] filter_input_array(INPUT_METHOD_NAME) instead of $_INPUT_METHOD_NAME

e.g

    $host= filter_input(INPUT_SERVER, 'HTTP_HOST');
    echo $host;

instead of

    $host= $_SERVER['HTTP_HOST'];
    echo $host;

And use

    var_dump(filter_input_array(INPUT_SERVER));

instead of

    var_dump($_SERVER);

N.B: Apply to all other Super Global variable

If you use CSS style, you can use:

$("#element").css("background-color","none"); 

and then replace with:

$("#element").css("background-color", color);

If you don't use CSS style and you have attribute in HTML element, you can use:

$("#element").attr("style.background-color",color);

You can use the datedif function to find out difference in days.

=DATEDIF(A1,TODAY(),"d")

Quote from excel.datedif.com

The mysterious datedif function in Microsoft Excel

The Datedif function is used to calculate interval between two dates in days, months or years.

This function is available in all versions of Excel but is not documented. It is not even listed in the "Insert Function" dialog box. Hence it must be typed manually in the formula box. Syntax

DATEDIF( start_date, end_date, interval_unit )

start_date from date end_date to date (must be after start_date) interval_unit Unit to be used for output interval Values for interval_unit

interval_unit Description

D Number of days

M Number of complete months

Y Number of complete years

YD Number of days excluding years

MD Number of days excluding months and years

YM Number of months excluding years

Errors

Error Description

#NUM! The end_date is later than (greater than) the start_date or interval_unit has an invalid value. #VALUE! end_date or start_date is invalid.

Java 8 Style for a given date

LocalDate today = LocalDate.of(1982, Month.AUGUST, 31);
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.ENGLISH)));
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.FRENCH)));
System.out.println(today.format(DateTimeFormatter.ofLocalizedDate(FormatStyle.MEDIUM).withLocale(Locale.JAPANESE)));

The post is old but I found a perfect CSS for the purpose and I want to share it.

A sticky element toggles between relative and fixed, depending on the scroll position. It is positioned relative until a given offset position is met in the viewport - then it "sticks" in place (like position:fixed).

    div.sticky {
        position: -webkit-sticky; /* Safari */
        position: sticky;
        top: 0;
        background-color: green;
        border: 2px solid #4CAF50;
    }

If your code is ES7 based (or upper versions):

channelArray.includes('three'); //will return true or false

If not, for example you are using IE with no babel transpile:

channelArray.indexOf('three') !== -1; //will return true or false

the indexOf method will return the position the element has into the array, because of that we use !== different from -1 if the needle is found at the first position.

The beauty of Server.Transfer is what you can do with it:

TextBox myTxt = (TextBox)this.Page.PreviousPage.FindControl("TextBoxID");

You can get anything from your previous page using the above method as long as you use Server.Transfer but not Response.Redirect

I just had thesame problem. With me the exe was still running but I could not end it with the Task Manager. Just by restarting VS, it worked for me.

Use:

Target= "_blank" property of anchor tag

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

I also got this type error, problem is wrong usage of parameters to statement like, Let's say you have a query like this

SELECT * FROM EMPLOYE E WHERE E.ID = ?

and for the preparedStatement object (JDBC) if you set the parameters like

preparedStatement.setXXX(1,value);
preparedStatement.setXXX(2,value)

then it results in SQLException: Invalid column index

So, I removed that second parameter setting to prepared statement then problem solved

Thought I'd throw in some simplified examples, just so the options are all out there:

Unique number (could also put this into a method):

AtomicInteger threadNum = new AtomicInteger(0);
ExecutorService e = Executors.newSingleThreadExecutor(r -> new Thread(r, "my-name-" + threadNum.incrementAndGet()));

Unique number and "probably" unique name (if you're generating new Runnable objects). Useful if starting off the threads is within a method that gets called more than once, for instance:

AtomicInteger threadNum = new AtomicInteger(0);
ExecutorService e = Executors.newSingleThreadExecutor(r -> new Thread(r, "my-name-" + threadNum.incrementAndGet() + "-" + r.hashCode()));

If you really wanted a unique name each time you'd need a class with a static var (and could also add a static pool number prefix in there as well, see other answers).

and an equivalent in JDK < 8 (you don't need a new class for it, or could return a ThreadFactory out of a method):

Executors.newSingleThreadExecutor(new ThreadFactory() {
      AtomicInteger threadCount = new AtomicInteger(0);

      @Override
      public Thread newThread(Runnable r) {
        return new Thread(r, "your-name-" + threadCount.getAndIncrement() + "-" + r.hashCode()); // could also use Integer.toHexString(r.hashCode()) for shorter
      }
    }));

And could make that into a method for the "you-name-" aspect as a variable. Or use a separate class with a constructor like the other answers all seem to.

I had this problem because I had a typo in my template near [(ngModel)]]. Extra bracket. Example:

<input id="descr" name="descr" type="text" required class="form-control width-half"
      [ngClass]="{'is-invalid': descr.dirty && !descr.valid}" maxlength="16" [(ngModel)]]="category.descr"
      [disabled]="isDescrReadOnly" #descr="ngModel">

I had the same problem while following a tutorial on setting up Laravel Homestead for Windows 10. The tutorial provides an example IP address 192.168.10.10 to use for the server. The problem with their example IP is that if you already have a VirtualBox Host-Only Adapter set up, the IP you use for your vagrant server must have the same first three parts of the IP address of your current adapter.

You can check what your current Virtualbox Host-Only Adapter IP address is by running ipconfig (windows) ifconfig (mac/linux) and looking for VirtualBox Host-Only Adapter's IPv4 address. 192.168.56.1 was mine. Usually if the host IP is 192.168.56.1 then the guest IP will be 192.168.56.101 so instead of using the example IP I used 192.168.56.102. Any IP that is within 192.168.56.* that is not already taken should work.

After this homestead up worked perfectly for me.

TL;DR - If your current VirtualBox Host-Only Adapter IP is 192.168.56.1, make your Vagrant server IP 192.168.56.102.

If you were using JGraph, you should give a try to JGraphT which is designed for algorithms. One of its features is visualization using the JGraph library. It's still developed, but pretty stable. I analyzed the complexity of JGraphT algorithms some time ago. Some of them aren't the quickest, but if you're going to implement them on your own and need to display your graph, then it might be the best choice. I really liked using its API, when I quickly had to write an app that was working on graph and displaying it later.

BComp.exe works in multiple-tabbed scenario as well, so there is no need to add /solo unless you really want separate windows for each file comparison. Tested/verified on Beyond Compare 3 and 4. Moral: use BComp.exe, not BCompare.exe, for VS external compare tool configuration.

You can also do it in one row:

if (MessageBox.Show("Text", "Title", MessageBoxButtons.YesNo) == DialogResult.Yes)

And if you want to show a messagebox on top:

if (MessageBox.Show(new Form() { TopMost = true }, "Text", "Text", MessageBoxButtons.YesNo) == DialogResult.Yes)

Multiple posted answer here, but probably this can help who is newly using PowerShell

SO if any space is there in your directory path do not forgot to add double inverted commas "".

You don't need to pass this, there already is the event object passed by default automatically, which contains event.target which has the object it's coming from. You can lighten your syntax:

This:

<p onclick="doSomething()">

Will work with this:

function doSomething(){
  console.log(event);
  console.log(event.target);
}

You don't need to instantiate the event object, it's already there. Try it out. And event.target will contain the entire object calling it, which you were referencing as "this" before.

Now if you dynamically trigger doSomething() from somewhere in your code, you will notice that event is undefined. This is because it wasn't triggered from an event of clicking. So if you still want to artificially trigger the event, simply use dispatchEvent:

document.getElementById('element').dispatchEvent(new CustomEvent("click", {'bubbles': true}));

Then doSomething() will see event and event.target as per usual!

No need to pass this everywhere, and you can keep your function signatures free from wiring information and simplify things.

Joining elements in a list space separated:

word = ["test", "crust", "must", "fest"]
word.reverse()
joined_string = ""
for w in word:
   joined_string = w + joined_string + " "
print(joined_string.rstrim())

I've just had a similar problem to this and finally figured out the cause: the application.properties file had the wrong ownership and rwx attributes. So when tomcat started up the application.properties file was in the right location, but owned by another user:

$ chmod 766 application.properties

$ chown tomcat application.properties

You can do the descending sort of a user-defined class this way overriding the compare() method,

Collections.sort(unsortedList,new Comparator<Person>() {
    @Override
    public int compare(Person a, Person b) {
        return b.getName().compareTo(a.getName());
    }
});

Or by using Collection.reverse() to sort descending as user Prince mentioned in his comment.

And you can do the ascending sort like this,

Collections.sort(unsortedList,new Comparator<Person>() {
    @Override
    public int compare(Person a, Person b) {
        return a.getName().compareTo(b.getName());
    }
});

Replace the above code with a Lambda expression(Java 8 onwards) we get concise:

Collections.sort(personList, (Person a, Person b) -> b.getName().compareTo(a.getName()));

As of Java 8, List has sort() method which takes Comparator as parameter(more concise) :

personList.sort((a,b)->b.getName().compareTo(a.getName()));

Here a and b are inferred as Person type by lambda expression.

it worked for me adding type="module" to the script importing my mjs:

<script type="module">
import * as module from 'https://rawgit.com/abernier/7ce9df53ac9ec00419634ca3f9e3f772/raw/eec68248454e1343e111f464e666afd722a65fe2/mymod.mjs'

console.log(module.default()) // Prints: Hi from the default export!
</script>

See demo: https://codepen.io/abernier/pen/wExQaa

Although this does not directly address your question, you can actually sort your data by cell colour in Excel (which then makes it pretty easy to label all records with a particular colour in the same way and, hence, condition upon this label).

In Excel 2010, you can do this by going to Data -> Sort -> Sort On "Cell Colour".

I prefer RENAME rather than DELETE

All my branches are named in the form of

• Fix/fix-<somedescription> or
• Ftr/ftr-<somedescription> or
• etc.

Using Tower as my git front end, it neatly organizes all the Ftr/, Fix/, Test/ etc. into folders.
Once I am done with a branch, I rename them to Done/...-<description>.

That way they are still there (which can be handy to provide history) and I can always go back knowing what it was (feature, fix, test, etc.)

An interesting project which could help you out in your task is JSS.

JSS is a better abstraction over CSS. It uses JavaScript as a language to describe styles in a declarative and maintainable way. It is a high performance JS to CSS compiler which works at runtime in the browsers and server-side.

JSS library allows you to inject in the DOM/head section using the .attach() function.

Repl online version for evaluation.

Further information on JSS.

An example:

// Use plugins.
jss.use(camelCase())

// Create your style.
const style = {
  myButton: {
    color: 'green'
  }
}

// Compile styles, apply plugins.
const sheet = jss.createStyleSheet(style)

// If you want to render on the client, insert it into DOM.
sheet.attach()

Here is what I use. All of these are in the Central and have sources.

The delete operator deletes only a reference, never an object itself. If it did delete the object itself, other remaining references would be dangling, like a C++ delete. (And accessing one of them would cause a crash. To make them all turn null would mean having extra work when deleting or extra memory for each object.)

Since Javascript is garbage collected, you don't need to delete objects themselves - they will be removed when there is no way to refer to them anymore.

It can be useful to delete references to an object if you are finished with them, because this gives the garbage collector more information about what is able to be reclaimed. If references remain to a large object, this can cause it to be unreclaimed - even if the rest of your program doesn't actually use that object.

Mallikarjun M, thank you!

fs-extra did the thing and it can even return a Promise if you do not provide a callback! :)

const path = require('path')
const fs = require('fs-extra')

let source = path.resolve( __dirname, 'folderA')
let destination = path.resolve( __dirname, 'folderB')

fs.copy(source, destination)
  .then(() => console.log('Copy completed!'))
  .catch( err => {
    console.log('An error occurred while copying the folder.')
    return console.error(err)
  })

I agree that Amazon appears to be intentionally obfuscating even how to find the API documentation, as well as use it. I'm just speculating though.

Renaming the services from "ECS" to "Product Advertising API" was probably also not the best move, it essentially invalidated all that Google mojo they had built up over time.

It took me quite a while to 'discover' this updated link for the Product Advertising API. I don't remember being able to easily discover it through the typical 'Developer' link on the Amazon webpage. This documentation appears to valid and what I've worked from recently.

The change to authentication procedures also seems to add further complexity, but I'm sure they have a reason for it.

I use SOAP via C# to communicate with Amazon Product API.

With the REST API you have to encrypt the whole URL in a fairly specific way. The params have to be sorted, etc. There is just more to do. With the SOAP API, you just encrypt the operation+timestamp, and thats it.

Adam O'Neil's post here, How to get album, dvd, and blueray cover art from Amazon, walks through the SOAP with C# method. Its not the original sample I pulled down, and contrary to his comment, it was not an official Amazon sample I stumbled on, though the code looks identical. However, Adam does a good job at presenting all the necessary steps. I wish I could credit the original author.

here's an example with the accepted answer:

 a = [{name:"alex"},{name:"clex"},{name:"blex"}];

For Ascending :

a.sort((a,b)=> (a.name > b.name ? 1 : -1))

output : [{name: "alex"}, {name: "blex"},{name: "clex"} ]

For Decending :

a.sort((a,b)=> (a.name < b.name ? 1 : -1))

output : [{name: "clex"}, {name: "blex"}, {name: "alex"}]

Please refer the below post. cmcculloh's answer worked for me. https://stackoverflow.com/posts/31683500/edit

As hinted at in the documentation, the easiest way to ensure that your tooltip does not wrap at all is to use

.tooltip-inner {
    max-width: none;
    white-space: nowrap;
}

With this, you don't have to worry about dimension values or anything like that. Main problem being if you have a super long line of text it will just go off of the screen (as you can see in the JSBin Example).

Update: This answer covers the general error classification. For a more specific answer about how to best handle the OP's exact query, please see other answers to this question

In MySQL, you can't modify the same table which you use in the SELECT part.
This behaviour is documented at: http://dev.mysql.com/doc/refman/5.6/en/update.html

Maybe you can just join the table to itself

If the logic is simple enough to re-shape the query, lose the subquery and join the table to itself, employing appropriate selection criteria. This will cause MySQL to see the table as two different things, allowing destructive changes to go ahead.

UPDATE tbl AS a
INNER JOIN tbl AS b ON ....
SET a.col = b.col

Alternatively, try nesting the subquery deeper into a from clause ...

If you absolutely need the subquery, there's a workaround, but it's ugly for several reasons, including performance:

UPDATE tbl SET col = (
  SELECT ... FROM (SELECT.... FROM) AS x);

The nested subquery in the FROM clause creates an implicit temporary table, so it doesn't count as the same table you're updating.

... but watch out for the query optimiser

However, beware that from MySQL 5.7.6 and onward, the optimiser may optimise out the subquery, and still give you the error. Luckily, the optimizer_switch variable can be used to switch off this behaviour; although I couldn't recommend doing this as anything more than a short term fix, or for small one-off tasks.

SET optimizer_switch = 'derived_merge=off';

Thanks to Peter V. Mørch for this advice in the comments.

Example technique was from Baron Schwartz, originally published at Nabble, paraphrased and extended here.

If xhr.abort(); causes page reload,

Then you can set onreadystatechange before abort to prevent:

// ? prevent page reload by abort()
xhr.onreadystatechange = null;
// ? may cause page reload
xhr.abort();

How about Application.EnableCancelKey - Use the Esc button

On Error GoTo handleCancel
Application.EnableCancelKey = xlErrorHandler
MsgBox "This may take a long time: press ESC to cancel"
For x = 1 To 1000000    ' Do something 1,000,000 times (long!)
    ' do something here
Next x

handleCancel:
If Err = 18 Then
    MsgBox "You cancelled"
End If

Snippet from http://msdn.microsoft.com/en-us/library/aa214566(office.11).aspx

Break statement will break the whole loop and execute the code after loop and Return will not execute the code after that return statement and execute the loop with next increment.

Break

for(int i=0;i<5;i++){
    print(i)
    if(i==2)
    {
      break;
    }
}

output: 0 1

return

for(int i=0;i<5;i++)

   print(i)
   if(i==2)
   {
    return;
   }
}

output: 0 1 3 4

Unless you have a specific reason to do raw ado.net I would have a look at using an ORM (object relational mapper) like nHibernate or LINQ to SQL. That way you can query the database and retrieve objects to work with which are strongly typed and easier to work with IMHO.

Just made this piece of code, wich converts "this.altura" from negative to positive number. Hope this helps someone in need

       if(this.altura < 0){    

                        String aux = Integer.toString(this.altura);
                        char aux2[] = aux.toCharArray();
                        aux = "";
                        for(int con = 1; con < aux2.length; con++){
                            aux += aux2[con];
                        }
                        this.altura = Integer.parseInt(aux);
                        System.out.println("New Value: " + this.altura);
                    }

Since no-one has yet wrote a function to do this with two integers, here's one way:

private long CalculatePower(int number, int powerOf)
{
    for (int i = powerOf; i > 1; i--)
        number *= number;
    return number;
}
CalculatePower(5, 3); // 125
CalculatePower(8, 4); // 4096
CalculatePower(6, 2); // 36

Alternatively in VB.NET:

Private Function CalculatePower(number As Integer, powerOf As Integer) As Long
    For i As Integer = powerOf To 2 Step -1
        number *= number
    Next
    Return number
End Function
CalculatePower(5, 3) ' 125
CalculatePower(8, 4) ' 4096
CalculatePower(6, 2) ' 36

You can create your own animations. Place animation XML files in res > anim

enter_from_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">

      android:duration="@android:integer/config_mediumAnimTime"/>
</set>

     android:fromYDelta="0%" android:toYDelta="0%"
     android:duration="@android:integer/config_mediumAnimTime" />
</set>

you can change the duration to short animation time

android:duration="@android:integer/config_shortAnimTime"

or long animation time

android:duration="@android:integer/config_longAnimTime" 

USAGE (note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):

FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

The answer, as Schmalzy points out, can be found here in the examples section of the getbootstrap site.

But that example does not include a top nav. For fixed top nav with sticky footer, see this plnkr, or code below.

If you are using BookId as an combined primary key, then remember to change your interface from:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, Long> {

to:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, BookId> {

And change the annotation @Embedded to @EmbeddedId, in your QueuedBook class like this:

public class QueuedBook implements Serializable {

@EmbeddedId
@NotNull
private BookId bookId;

...

This worked for me (using jQuery 2.1)

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        s.data += s.data?"&":"";
        s.data += "_token=" + $('#csrf-token').val();
    }
});

or this:

$(document).ajaxSend(function(elm, xhr, s){
    if (s.type == "POST") {
        xhr.setRequestHeader('x-csrf-token', $('#csrf-token').val());
    }
});

(where #csrf-token is the element containing the token)

As stated by user2246674, using success and error as parameter of the ajax function is valid.

To be consistent with precedent answer, reading the doc :

Deprecation Notice:

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks will be deprecated in jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

If you are using the callback-manipulation function (using method-chaining for example), use .done(), .fail() and .always() instead of success(), error() and complete().

Use mixins

@mixin sentence-case() {_x000D_
  text-transform: lowercase;_x000D_
  &:first-letter {_x000D_
    text-transform: uppercase;_x000D_
  }_x000D_
}_x000D_
_x000D_
// USAGE:_x000D_
.title {_x000D_
  @include sentence-case();_x000D_
}

Use below code to change background color of edit-text's border.

Create new XML file under drawable.

abc.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#00000000" />
    <stroke android:width="1dip" android:color="#ffffff" />
</shape>

and add it as background of your edit-text

android:background="@drawable/abc"

@people = qw( bob john linda ); 
$n = @people; # the number 3
Print " le number in the list is $n \n"; 

Expressions in Perl always return the appropriate value for their context. For example, how about the “name” * of an array. In a list context, it gives the list of elements. But in a scalar context, it returns the number of elements in the array:

complete executes after either the success or error callback were executed.

Maybe you should check the second parameter complete offers too. It's a String holding the type of success the ajaxCall had.

The different callbacks are described a little more in detail here jQuery.ajax( options )

I guess you missed the fact that the complete and the success function (I know inconsistent API) get different data passed in. success gets only the data, complete gets the whole XMLHttpRequest object. Of course there is no responseText property on the data string.

So if you replace complete with success you also have to replace data.responseText with data only.

success

The function gets passed two arguments: The data returned from the server, formatted according to the 'dataType' parameter, and a string describing the status.

complete

The function gets passed two arguments: The XMLHttpRequest object and a string describing the type of success of the request.

If you need to have access to the whole XMLHttpRequest object in the success callback I suggest trying this.

var myXHR = $.ajax({
    ...
    success: function(data, status) {
        ...do whatever with myXHR; e.g. myXHR.responseText...
    },
    ...
});

No. You have to make your own like this:

boolean tryParseInt(String value) {  
     try {  
         Integer.parseInt(value);  
         return true;  
      } catch (NumberFormatException e) {  
         return false;  
      }  
}

...and you can use it like this:

if (tryParseInt(input)) {  
   Integer.parseInt(input);  // We now know that it's safe to parse
}

EDIT (Based on the comment by @Erk)

Something like follows should be better

public int tryParse(String value, int defaultVal) {
    try {
        return Integer.parseInt(value);
    } catch (NumberFormatException e) {
        return defaultVal;
    }
}

When you overload this with a single string parameter method, it would be even better, which will enable using with the default value being optional.

public int tryParse(String value) {
    return tryParse(value, 0)
}

If your intent is to copy the found files into /home/shantanu/tosend, you have the order of the arguments to cp reversed:

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp "{}" /home/shantanu/tosend  \;

Please, note: the find command use {} as placeholder for matched file.

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

 function integerDivison(dividend, divisor){
    
        this.Division  = dividend/divisor;
        this.Quotient = Math.floor(dividend/divisor);
         this.Remainder = dividend%divisor;
        this.calculate = ()=>{
            return {Value:this.Division,Quotient:this.Quotient,Remainder:this.Remainder};
        }
         
    }

  var divide = new integerDivison(5,2);
  console.log(divide.Quotient)      //to get Quotient of two value 
  console.log(divide.division)     //to get Floating division of two value 
  console.log(divide.Remainder)     //to get Remainder of two value 
  console.log(divide.calculate())   //to get object containing all the values

There are multiple approaches you can choose from:

1. Approach: FileReader

Load the image as blob via XMLHttpRequest and use the FileReader API (readAsDataURL()) to convert it to a dataURL:

function toDataURL(url, callback) {
  var xhr = new XMLHttpRequest();
  xhr.onload = function() {
    var reader = new FileReader();
    reader.onloadend = function() {
      callback(reader.result);
    }
    reader.readAsDataURL(xhr.response);
  };
  xhr.open('GET', url);
  xhr.responseType = 'blob';
  xhr.send();
}

toDataURL('https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0', function(dataUrl) {
  console.log('RESULT:', dataUrl)
})

This code example could also be implemented using the WHATWG fetch API:

const toDataURL = url => fetch(url)
  .then(response => response.blob())
  .then(blob => new Promise((resolve, reject) => {
    const reader = new FileReader()
    reader.onloadend = () => resolve(reader.result)
    reader.onerror = reject
    reader.readAsDataURL(blob)
  }))


toDataURL('https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0')
  .then(dataUrl => {
    console.log('RESULT:', dataUrl)
  })

These approaches:

• lack in browser support

• have better compression
• work for other file types as well

Browser Support:

• http://caniuse.com/#feat=filereader
• http://caniuse.com/#feat=fetch

2. Approach: Canvas

Load the image into an Image-Object, paint it to a nontainted canvas and convert the canvas back to a dataURL.

function toDataURL(src, callback, outputFormat) {
  var img = new Image();
  img.crossOrigin = 'Anonymous';
  img.onload = function() {
    var canvas = document.createElement('CANVAS');
    var ctx = canvas.getContext('2d');
    var dataURL;
    canvas.height = this.naturalHeight;
    canvas.width = this.naturalWidth;
    ctx.drawImage(this, 0, 0);
    dataURL = canvas.toDataURL(outputFormat);
    callback(dataURL);
  };
  img.src = src;
  if (img.complete || img.complete === undefined) {
    img.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";
    img.src = src;
  }
}

toDataURL(
  'https://www.gravatar.com/avatar/d50c83cc0c6523b4d3f6085295c953e0',
  function(dataUrl) {
    console.log('RESULT:', dataUrl)
  }
)

In detail

Supported input formats:

image/png, image/jpeg, image/jpg, image/gif, image/bmp, image/tiff, image/x-icon, image/svg+xml, image/webp, image/xxx

Supported output formats:

image/png, image/jpeg, image/webp(chrome)

Browser Support:

• http://caniuse.com/#feat=canvas

• Internet Explorer 10 (Internet Explorer 10 just works with same origin images)

3. Approach: Images from the local file system

If you want to convert images from the users file system you need to take a different approach. Use the FileReader API:

function encodeImageFileAsURL(element) {
  var file = element.files[0];
  var reader = new FileReader();
  reader.onloadend = function() {
    console.log('RESULT', reader.result)
  }
  reader.readAsDataURL(file);
}

<input type="file" onchange="encodeImageFileAsURL(this)" />

It has some interesting behaviour in some cases that is good to be aware of:

from werkzeug.datastructures import MultiDict

d = MultiDict([("ex1", ""), ("ex2", None)])

d.get("ex1", "alternive")
# returns: ''

d.get("ex2", "alternative")
# returns no visible output of any kind
# It is returning literally None, so if you do:
d.get("ex2", "alternative") is None
# it returns: True

d.get("ex3", "alternative")
# returns: 'alternative'

Well, its not compulsory to restart the emulator you can also reset adb from eclipse itself.

1.) Go to DDMS and there is a reset adb option, please see the image below.

2.) You can restart adb manually from command prompt

  run->cmd->your_android_sdk_path->platform-tools>

Then write the below commands.

adb kill-server - To kill the server forcefully

adb start-server - To start the server

UPDATED:

F:\android-sdk-windows latest\platform-tools>adb kill-server

F:\android-sdk-windows latest\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

If you are creating an array then there is no difference, however, the following is neater:

String[] suit = {
  "spades", 
  "hearts", 
  "diamonds", 
  "clubs"  
};

But, if you want to pass an array into a method you have to call it like this:

myMethod(new String[] {"spades", "hearts"});

myMethod({"spades", "hearts"}); //won't compile!

You can create a list,

ArrayList<String[]> outerArr = new ArrayList<String[]>(); 

and add other lists to it like so:

String[] myString1= {"hey","hey","hey","hey"};  
outerArr .add(myString1);
String[] myString2= {"you","you","you","you"};
outerArr .add(myString2);

Now you can use the double loop below to show everything inside all lists

for(int i=0;i<outerArr.size();i++){

   String[] myString= new String[4]; 
   myString=outerArr.get(i);
   for(int j=0;j<myString.length;j++){
      System.out.print(myString[j]); 
   }
   System.out.print("\n");

}

You can't clone it, and how you are going to solve your problem depends on what the source of the data is.

One solution is to read all data from the InputStream into a byte array, and then create a ByteArrayInputStream around that byte array, and pass that input stream into your method.

Edit 1: That is, if the other method also needs to read the same data. I.e you want to "reset" the stream.

Try

fetch(form.action,{method:'post', body: new FormData(form)});

function send(e,form) {_x000D_
  fetch(form.action,{method:'post', body: new FormData(form)});_x000D_
_x000D_
  console.log('We submit form asynchronously (AJAX)');_x000D_
  e.preventDefault();_x000D_
}

<form method="POST" action="myapi/send" onsubmit="send(event,this)" name="orderproductForm">_x000D_
    <input hidden name="csrfToken" value="$0meh@$h">_x000D_
    <input name="email" value="[email protected]">_x000D_
    <input name="phone" value="123-456-666">_x000D_
    <input type="submit">    _x000D_
</form>_x000D_
_x000D_
Look on Chrome Console > Network after/before 'submit'

This expands on Paul's answer. In Pandas, indexing a DataFrame returns a reference to the initial DataFrame. Thus, changing the subset will change the initial DataFrame. Thus, you'd want to use the copy if you want to make sure the initial DataFrame shouldn't change. Consider the following code:

df = DataFrame({'x': [1,2]})
df_sub = df[0:1]
df_sub.x = -1
print(df)

You'll get:

x
0 -1
1  2

In contrast, the following leaves df unchanged:

df_sub_copy = df[0:1].copy()
df_sub_copy.x = -1

I setup a short cut (using windows) and set the target to

C:\Python36\pythonw.exe c:/python36/Lib/idlelib/idle.py

works great

Also found this works

with open('FILE.py') as f:
    exec(f.read())

You don't need hibernate-entitymanager-xxx.jar, because of you use a Hibernate session approach (not JPA). You need to close the SessionFactory too and rollback a transaction on errors. But, the problem, of course, is not with those.

This is returned by a database

#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"
#

Looks like you've provided an incorrect username or (and) password.

This should give you the current date minus 1 year:

select now() - interval '1 year';

Here is a generic LINQ extension method that does not create an extra copy of the list:

public static void Sort<T,U>(this List<T> list, Func<T, U> expression)
    where U : IComparable<U>
{
    list.Sort((x, y) => expression.Invoke(x).CompareTo(expression.Invoke(y)));
}

To use it:

myList.Sort(x=> x.myProperty);

I recently built this additional one which accepts an ICompare<U>, so that you can customize the comparison. This came in handy when I needed to do a Natural string sort:

public static void Sort<T, U>(this List<T> list, Func<T, U> expression, IComparer<U> comparer)
    where U : IComparable<U>
{    
    list.Sort((x, y) => comparer.Compare(expression.Invoke(x), expression.Invoke(y)));
}

See at the bottom of this page at Python wiki, there are at least 2 options to "unescape" html.

                    for (int p = 0; p < dim_x; p++) {
                        for (int q = 0; q < dim_y; q++) {
                           newVisitedMap[p][q] = visitedMap[p][q];
                        }

                    newVisitedMap[i][j] = 1;
                    checkAndPrint(word + matrix[i][j]);
                    recursion(word + matrix[i][j], newVisitedMap, i, j);
                }
            }
        }
    }

A bit late but might be a useful solution. I am using my TabLayout directly in my Fragment and trying to select a tab quite early in the Fragment's Lifecycle. What worked for me was to wait until the TabLayout finished drawing its child views by using android.view.View#post method. i.e:

int myPosition = 0;
myFilterTabLayout.post(() -> { filterTabLayout.getTabAt(myPosition).select(); });

DEMO

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

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

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

Nothing worked until I went this way: Settings>Developer options>Default USB configuration now you can choose your default USB connection purpose.

I was banging my head against a wall with this issue for a while. In our environment, we consume price files from our suppliers in various formats, some of which have upward of a million records. This issue usually occurs where:

• The rows scanned by the OLEDB driver appear to contain numbers, but do contain mixed values later on in the record set, or
• Fields do contain only numbers, but the source has some formatted as text (usually Excel files).

The problem is that even if you set your external input column to the desired data type, the file gets scanned every time you run the package and is dynamically changed to whatever the OLEDB driver thinks the field should be.

Our source files typically contain field headers (text) and prices (numeric fields), which gives me an easy solution:

First step:

• Change your SQL statement to include the header fields. This forces SSIS to see all fields as text, including the price fields.

For mixed fields:

• Your initial problem is solved because your fields are now text, but you still have a header row in your output.
• Prevent the header row from making it into your output by changing the SQL WHERE clause to exclude the header values e.g. "WHERE NOT([F4]='Price')"

For numeric fields:

• Using the advanced editor for the OLE DB source, set the output column for the price field (or any other numeric field) to a numeric DataType. This causes any records that contain text in these fields to fail, including the header record, but forces a conversion on numeric values saved as text.

• Set the Error Output to ignore failures on your numeric fields.

• Alternatively, if you still need any errors on the numeric fields redirected, remove the header row by changing the SQL WHERE clause to exclude the header values then,

• Set the Error Output to redirect failures on this field.

Obviously this method only works where you have header fields, but hopefully this helps some of you.

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

class someclass:
        x=1
        y=2
        z=3
        def __init__(self):
           self.current_idx = 0
           self.items = ["x","y","z"]
        def next(self):
            if self.current_idx < len(self.items):
                self.current_idx += 1
                k = self.items[self.current_idx-1]
                return (k,getattr(self,k))
            else:
                raise StopIteration
        def __iter__(self):
           return self

then just call it as an iterable

s=someclass()
for k,v in s:
    print k,"=",v

You can't do

LivingRoom.objects.create(user=instance)

because you have an __init__ method that does NOT take user as argument.

You need something like

#signal function: if a user is created, add control livingroom to the user    
def create_control_livingroom(sender, instance, created, **kwargs):
    if created:
        my_room = LivingRoom()
        my_room.user = instance

Update

But, as bruno has already said it, Django's models.Model subclass's initializer is best left alone, or should accept *args and **kwargs matching the model's meta fields.

So, following better principles, you should probably have something like

class LivingRoom(models.Model):
    '''Living Room object'''
    user = models.OneToOneField(User)

    def __init__(self, *args, temp=65, **kwargs):
        self.temp = temp
        return super().__init__(*args, **kwargs)

Note - If you weren't using temp as a keyword argument, e.g. LivingRoom(65), then you'll have to start doing that. LivingRoom(user=instance, temp=66) or if you want the default (65), simply LivingRoom(user=instance) would do.

Here is another way as an alternative:

Write-Host (" {0}  -  {1}  -  {2}" -f $assoc.Id, $assoc.Name, $assoc.Owner)

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

Add timeout of your SqlCommand. Please note time is in second.

// Setting command timeout to 1 second
scGetruntotals.CommandTimeout = 1;

Well considering there's no overhead difference between a varchar(30) and a varchar(100) if you're only storing 20 characters in each, err on the side of caution and just make it 50.

As a workaround to this limitation, I use two rules to cover all the cases.

For example, if I want to allow or deny these 18 ports:

465,110,995,587,143,11025,20,21,22,26,80,443,3000,10000,7080,8080,3000,5666

I use the below rules:

iptables -A INPUT -p tcp -i eth0 -m multiport --dports 465,110,995,587,143,11025,20,21,22,26,80,443 -j ACCEPT

iptables -A INPUT -p tcp -i eth0 -m multiport --dports 3000,10000,7080,8080,3000,5666 -j ACCEPT

The above rules should work for your scenario also. You can create another rule if you hit 15 ports limit on both first and second rule.

With apologies and thanks to yukondude.

I've tried to summarise the timing settings for easy reading, though it's not a perfect job, and I don't touch 'every Friday' or 'only on Mondays' stuff.

This is version 10 - it now:

• runs much much faster
• has optional progress characters so you could improve the speed further.
• uses a divider line to separate header and output.
• outputs in a compact format when all timing intervals uencountered can be summarised.
• Accepts Jan...Dec descriptors for months-of-the-year
• Accepts Mon...Sun descriptors for days-of-the-week
• tries to handle debian-style dummying-up of anacron when it is missing
• tries to deal with crontab lines which run a file after pre-testing executability using "[ -x ... ]"
• tries to deal with crontab lines which run a file after pre-testing executability using "command -v"
• allows the use of interval spans and lists.
• supports run-parts usage in user-specific /var/spool crontab files.

I am now publishing the script in full here.

Even though 7 years have passed I've just run into this issue as I'm running SpringBoot application that needs to start webpack-dev-server during development and needs to kill it when the backend process stops.

I try to use Runtime.getRuntime().addShutdownHook but it worked on Windows 10 but not on Windows 7.

I've change it to use a dedicated thread that waits for the process to quit or for InterruptedException which seems to work correctly on both Windows versions.

private void startWebpackDevServer() {
    String cmd = isWindows() ? "cmd /c gradlew webPackStart" : "gradlew webPackStart";
    logger.info("webpack dev-server " + cmd);

    Thread thread = new Thread(() -> {

        ProcessBuilder pb = new ProcessBuilder(cmd.split(" "));
        pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
        pb.redirectError(ProcessBuilder.Redirect.INHERIT);
        pb.directory(new File("."));

        Process process = null;
        try {
            // Start the node process
            process = pb.start();

            // Wait for the node process to quit (blocking)
            process.waitFor();

            // Ensure the node process is killed
            process.destroyForcibly();
            System.setProperty(WEBPACK_SERVER_PROPERTY, "true");
        } catch (InterruptedException | IOException e) {
            // Ensure the node process is killed.
            // InterruptedException is thrown when the main process exit.
            logger.info("killing webpack dev-server", e);
            if (process != null) {
                process.destroyForcibly();
            }
        }

    });

    thread.start();
}

1> $a = "This", "Is", "a", "cat"

2> [system.String]::Join(" ", $a)

Line two performs the operation and outputs to host, but does not modify $a:

3> $a = [system.String]::Join(" ", $a)

4> $a

This Is a cat

5> $a.Count

As to the cause, the <f:attribute> is specific to the component itself (populated during view build time), not to the iterated row (populated during view render time).

There are several ways to achieve the requirement.

1. If your servletcontainer supports a minimum of Servlet 3.0 / EL 2.2, then just pass it as an argument of action/listener method of UICommand component or AjaxBehavior tag. E.g.

    <h:commandLink action="#{bean.insert(item.id)}" value="insert" />
   

   In combination with:

    public void insert(Long id) {
        // ...
    }
   

   This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   You can even pass the entire item object:

    <h:commandLink action="#{bean.insert(item)}" value="insert" />
   

   with:

    public void insert(Item item) {
        // ...
    }
   

   On Servlet 2.5 containers, this is also possible if you supply an EL implementation which supports this, like as JBoss EL. For configuration detail, see this answer.

   ---

2. Use <f:param> in UICommand component. It adds a request parameter.

    <h:commandLink action="#{bean.insert}" value="insert">
        <f:param name="id" value="#{item.id}" />
    </h:commandLink>
   

   If your bean is request scoped, let JSF set it by @ManagedProperty

    @ManagedProperty(value="#{param.id}")
    private Long id; // +setter
   

   Or if your bean has a broader scope or if you want more fine grained validation/conversion, use <f:viewParam> on the target view, see also f:viewParam vs @ManagedProperty:

    <f:viewParam name="id" value="#{bean.id}" required="true" />
   

   Either way, this has the advantage that the datamodel doesn't necessarily need to be preserved for the form submit (for the case that your bean is request scoped).

   ---

3. Use <f:setPropertyActionListener> in UICommand component. The advantage is that this removes the need for accessing the request parameter map when the bean has a broader scope than the request scope.

    <h:commandLink action="#{bean.insert}" value="insert">
        <f:setPropertyActionListener target="#{bean.id}" value="#{item.id}" />
    </h:commandLink>
   

   In combination with

    private Long id; // +setter
   

   It'll be just available by property id in action method. This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   ---

4. Bind the datatable value to DataModel<E> instead which in turn wraps the items.

    <h:dataTable value="#{bean.model}" var="item">
   

   with

    private transient DataModel<Item> model;
   
    public DataModel<Item> getModel() {
        if (model == null) {
            model = new ListDataModel<Item>(items);
        }
        return model;
    }
   

   (making it transient and lazily instantiating it in the getter is mandatory when you're using this on a view or session scoped bean since DataModel doesn't implement Serializable)

   Then you'll be able to access the current row by DataModel#getRowData() without passing anything around (JSF determines the row based on the request parameter name of the clicked command link/button).

    public void insert() {
        Item item = model.getRowData();
        Long id = item.getId();
        // ...
    }
   

   This also requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   ---

5. Use Application#evaluateExpressionGet() to programmatically evaluate the current #{item}.

    public void insert() {
        FacesContext context = FacesContext.getCurrentInstance();
        Item item = context.getApplication().evaluateExpressionGet(context, "#{item}", Item.class);
        Long id = item.getId();
        // ...
    }
   

   ---

Which way to choose depends on the functional requirements and whether the one or the other offers more advantages for other purposes. I personally would go ahead with #1 or, when you'd like to support servlet 2.5 containers as well, with #2.

As I understand Copy-Item -Exclude then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item as in

Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item  -Path $copyAdmin -Destination $AdminPath -Recurse -force

I had the same problem, there was no extension=php_soap.dll in my php.ini But this was because I had copied the php.ini from a old and previous php version (not a good idea). I found the dll in the ext directory so I just could put it myself into the php.ini extension=php_soap.dll After Apache restart all worked with soap :)

private async void Ping_Click(object sender, RoutedEventArgs e)
{
    Ping pingSender = new Ping();
    string host = @"stackoverflow.com";
    await Task.Run(() =>{
         PingReply reply = pingSender.Send(host);
         if (reply.Status == IPStatus.Success)
         {
            Console.WriteLine("Address: {0}", reply.Address.ToString());
            Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
            Console.WriteLine("Time to live: {0}", reply.Options.Ttl);
            Console.WriteLine("Don't fragment: {0}", reply.Options.DontFragment);
            Console.WriteLine("Buffer size: {0}", reply.Buffer.Length);
         }
         else
         {
            Console.WriteLine("Address: {0}", reply.Status);
         }
   });           
}

I had the same problem but finally I found the way.

Here is the walk through:

1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)

2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.

3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:

:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}

NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...

NOTE: You can see, the video codec is MP4V which is supported by android.

4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:

5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...

Question: Anybody know how to reduce buffering time and play video almost live ?

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

I'd say just divide it by 2 and if there is a 0 remainder, it's even, otherwise it's odd.

Using the modulus (%) makes this easy.

eg. 4 % 2 = 0 therefore 4 is even 5 % 2 = 1 therefore 5 is odd

How about

$ext = array_pop($userfile_extn);

Here is one possiblity for you if you are using Bootstrap 3

I'm using the resposive table code from http://getbootstrap.com/css/#tables-responsive

ie:

<div class="table-responsive">

There is a newer, less mature curl wrapper being developed called C++ Requests. Here's a simple GET request:

#include <iostream>
#include <cpr.h>

int main(int argc, char** argv) {
    auto response = cpr::Get(cpr::Url{"http://httpbin.org/get"});
    std::cout << response.text << std::endl;
}

It supports a wide variety of HTTP verbs and curl options. There's more usage documentation here.

Disclaimer: I'm the maintainer of this library.

I am using Intents to communicate actions back to the main activity. The main activity is listening to these by overriding onNewIntent(Intent intent). The main activity translates these actions to the corresponding fragments for example.

So you can do something like this:

public class MainActivity extends Activity  {

    public static final String INTENT_ACTION_SHOW_FOO = "show_foo";
    public static final String INTENT_ACTION_SHOW_BAR = "show_bar";


   @Override
   protected void onNewIntent(Intent intent) {
        routeIntent(intent);
   }

  private void routeIntent(Intent intent) {
       String action = intent.getAction();
       if (action != null) {               
            switch (action) {
            case INTENT_ACTION_SHOW_FOO:
                // for example show the corresponding fragment
                loadFragment(FooFragment);
                break;
            case INTENT_ACTION_SHOW_BAR:
                loadFragment(BarFragment);
                break;               
        }
    }
}

Then inside any fragment to show the foo fragment:

Intent intent = new Intent(context, MainActivity.class);
intent.setAction(INTENT_ACTION_SHOW_FOO);
// Prevent activity to be re-instantiated if it is already running.
// Instead, the onNewEvent() is triggered
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
getContext().startActivity(intent);

Code should be written to be understandable to the programmer first, and the compiler or interpreter second. The "is not" construct resembles English more closely than "not is".

You could try this

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),FALSE, TRUE)

-or-

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),"FALSE", "File found in row "   & MATCH(<single column I value>,<entire column E range>,0))

you could replace <single column I value> and <entire column E range> with named ranged. That'd probably be the easiest.

Just drag that formula all the way down the length of your I column in whatever column you want.

In my case we were setting the div id as a number and setting the href="#123", this did not work.. adding a prefix to the id helped.

Example: This did not work-

<li> <a data-toggle="tab" href="#@i"> <li/>
...
<div class="tab-pane" id="#@i">

This worked:

<li><a data-toggle="tab" href="#prefix@i"><li/>
...
<div class="tab-pane" id="#prefix@i">

tl;dr

Use java.time.Instant class to parse text in standard ISO 8601 format, representing a moment in UTC.

Instant.parse( "2010-10-02T12:23:23Z" )

ISO 8601

That format is defined by the ISO 8601 standard for date-time string formats.

Both:

• java.time framework built into Java 8 and later (Tutorial)
• Joda-Time library

…use ISO 8601 formats by default for parsing and generating strings.

You should generally avoid using the old java.util.Date/.Calendar & java.text.SimpleDateFormat classes as they are notoriously troublesome, confusing, and flawed. If required for interoperating, you can convert to and fro.

java.time

Built into Java 8 and later is the new java.time framework. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

Instant instant = Instant.parse( "2010-10-02T12:23:23Z" );  // `Instant` is always in UTC.

Convert to the old class.

java.util.Date date = java.util.Date.from( instant );  // Pass an `Instant` to the `from` method.

Time Zone

If needed, you can assign a time zone.

ZoneId zoneId = ZoneId.of( "America/Montreal" ); // Define a time zone rather than rely implicitly on JVM’s current default time zone.
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );  // Assign a time zone adjustment from UTC.

Convert.

java.util.Date date = java.util.Date.from( zdt.toInstant() );  // Extract an `Instant` from the `ZonedDateTime` to pass to the `from` method.

Joda-Time

UPDATE: The Joda-Time project is now in maintenance mode. The team advises migration to the java.time classes.

Here is some example code in Joda-Time 2.8.

org.joda.time.DateTime dateTime_Utc = new DateTime( "2010-10-02T12:23:23Z" , DateTimeZone.UTC );  // Specifying a time zone to apply, rather than implicitly assigning the JVM’s current default.

Convert to old class. Note that the assigned time zone is lost in conversion, as j.u.Date cannot be assigned a time zone.

java.util.Date date = dateTime_Utc.toDate(); // The `toDate` method converts to old class.

Time Zone

If needed, you can assign a time zone.

DateTimeZone zone = DateTimeZone.forID( "America/Montreal" );
DateTime dateTime_Montreal = dateTime_Utc.withZone ( zone );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

IF you have done everything above and still nothing worked for you then try adding $(inherited) in Framework search path of your target's build setting.

If you are using maven then you can add the tomcat7-maven-plugin to your pom.xml and it shall run fine. This plugin will run the project on Tomcat servlet container version 7.0.47 which supports JDK 1.8.

Here is the explanation:

https://www.w3.org/TR/css-flexbox-1/#flex-common

flex: <positive-number>
Equivalent to flex: <positive-number> 1 0. Makes the flex item flexible and sets the flex basis to zero, resulting in an item that receives the specified proportion of the free space in the flex container. If all items in the flex container use this pattern, their sizes will be proportional to the specified flex factor.

Therefore flex:1 is equivalent to flex: 1 1 0

From http://pmob.co.uk/pob/centred-float.htm:

The premise is simple and basically just involves a widthless float wrapper that is floated to the left and then shifted off screen to the left width position:relative; left:-50%. Next the nested inner element is reversed and a relative position of +50% is applied. This has the effect of placing the element dead in the center. Relative positioning maintains the flow and allows other content to flow underneath.

Code

#buttons{
    float:right;
    position:relative;
    left:-50%;
    text-align:left;
}
#buttons ul{
    list-style:none;
    position:relative;
    left:50%;
}

#buttons li{float:left;position:relative;}/* ie needs position:relative here*/

#buttons a{
    text-decoration:none;
    margin:10px;
    background:red;
    float:left;
    border:2px outset blue;
    color:#fff;
    padding:2px 5px;
    text-align:center;
    white-space:nowrap;
}
#buttons a:hover{ border:2px inset blue;color:red;background:#f2f2f2;}
#content{overflow:hidden}/* hide horizontal scrollbar*/

<div id="buttons">
    <ul>
        <li><a href="#">Button 1</a></li>
        <li><a href="#">Button 2's a bit longer</a></li>
        <li><a href="#">Butt 3</a></li>
        <li><a href="#">Button 4</a></li>
    </ul>
</div>

2^31-1 bytes. So, a little less than 2^31-1 characters for varchar(max) and half that for nvarchar(max).

nchar and nvarchar

One other thing. You may need to specify the -L option as well - eg

-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz

or you may end up with an error like

ld: cannot find -lbaz

The accepted answer already mentions PEP 238. I just want to add a quick look behind the scenes for those interested in what's going on without reading the whole PEP.

Python maps operators like +, -, * and / to special functions, such that e.g. a + b is equivalent to

a.__add__(b)

Regarding division in Python 2, there is by default only / which maps to __div__ and the result is dependent on the input types (e.g. int, float).

Python 2.2 introduced the __future__ feature division, which changed the division semantics the following way (TL;DR of PEP 238):

• / maps to __truediv__ which must "return a reasonable approximation of the mathematical result of the division" (quote from PEP 238)
• // maps to __floordiv__, which should return the floored result of /

With Python 3.0, the changes of PEP 238 became the default behaviour and there is no more special method __div__ in Python's object model.

If you want to use the same code in Python 2 and Python 3 use

from __future__ import division

and stick to the PEP 238 semantics of / and //.

Your transfer speed is likely not to be limited by Java. Instead I would suspect (in no particular order)

1. the speed of transfer from the database
2. the speed of transfer to the disk

If you read the complete dataset and then write it out to disk, then that will take longer, since the JVM will have to allocate memory, and the db rea/disk write will happen sequentially. Instead I would write out to the buffered writer for every read that you make from the db, and so the operation will be closer to a concurrent one (I don't know if you're doing that or not)

I know it's an old thread, but I landed here several times via Google and think no given answer is really satisfying yet. Try using one of the following functions:

EDIT: As I'm getting some likes on this old thread, I wanna share an updated solution as well (basically putting my two previous functions together and automatically deciding whether it's a bar or hbar plot):

def label_bars(ax, bars, text_format, **kwargs):
    """
    Attaches a label on every bar of a regular or horizontal bar chart
    """
    ys = [bar.get_y() for bar in bars]
    y_is_constant = all(y == ys[0] for y in ys)  # -> regular bar chart, since all all bars start on the same y level (0)

    if y_is_constant:
        _label_bar(ax, bars, text_format, **kwargs)
    else:
        _label_barh(ax, bars, text_format, **kwargs)


def _label_bar(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    """
    max_y_value = ax.get_ylim()[1]
    inside_distance = max_y_value * 0.05
    outside_distance = max_y_value * 0.01

    for bar in bars:
        text = text_format.format(bar.get_height())
        text_x = bar.get_x() + bar.get_width() / 2

        is_inside = bar.get_height() >= max_y_value * 0.15
        if is_inside:
            color = "white"
            text_y = bar.get_height() - inside_distance
        else:
            color = "black"
            text_y = bar.get_height() + outside_distance

        ax.text(text_x, text_y, text, ha='center', va='bottom', color=color, **kwargs)


def _label_barh(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    Note: label always outside. otherwise it's too hard to control as numbers can be very long
    """
    max_x_value = ax.get_xlim()[1]
    distance = max_x_value * 0.0025

    for bar in bars:
        text = text_format.format(bar.get_width())

        text_x = bar.get_width() + distance
        text_y = bar.get_y() + bar.get_height() / 2

        ax.text(text_x, text_y, text, va='center', **kwargs)

Now you can use them for regular bar plots:

fig, ax = plt.subplots((5, 5))
bars = ax.bar(x_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, bars, value_format)

or for horizontal bar plots:

fig, ax = plt.subplots((5, 5))
horizontal_bars = ax.barh(y_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, horizontal_bars, value_format)

Expression: "Total Count: " + (DT_WSTR, 11)@[User::int32Value]

for Int32 -- (-2,147,483,648 to 2,147,483,647)

Before asking questions of this kind, please check MSDN documentation.

When you divide two integers, the result is always an integer. For example, the result of 7 / 3 is 2. To determine the remainder of 7 / 3, use the remainder operator (%).

int a = 5;
int b = 3;

int div = a / b; //quotient is 1
int mod = a % b; //remainder is 2

to use white space in xml as string use  . XML won't take white space as it is. it will trim the white space before setting it. So use   instead of single white space

var SlectedList = new Array();
$("input.yorcheckboxclass:checked").each(function() {
     SlectedList.push($(this).val());
});

Add this to your main CSS:

table td {
    border-top: none !important;
}

Use this for newer versions of bootstrap:

.table th, .table td { 
     border-top: none !important; 
 }

The following solution works for me in TensorFlow 2.3 -

def load_pb(path_to_pb):
    with tf.io.gfile.GFile(path_to_pb, 'rb') as f:
        graph_def = tf.compat.v1.GraphDef()
        graph_def.ParseFromString(f.read())
    with tf.Graph().as_default() as graph:
        tf.import_graph_def(graph_def, name='')
        return graph

tf_graph = load_pb(MODEL_FILE)
sess = tf.compat.v1.Session(graph=tf_graph)

# Show tensor names in graph
for op in tf_graph.get_operations():
    print(op.values())

where MODEL_FILE is the path to your frozen graph.

Build and undo the version, Build. 2.1.6.RELEASE to 1.3.3.RELEASE Build Undo 1.3.3 to 2.1.6 Build (in my case problem solved) It helped us.

Two ways:

Use indexes:

double sum = 0;
for(int i = 0; i < m.size(); i++)
    sum += m.get(i);
return sum;

Use the "for each" style:

double sum = 0;
for(Double d : m)
    sum += d;
return sum;

Convert tuple to list:

>>> t = ('my', 'name', 'is', 'mr', 'tuple')
>>> t
('my', 'name', 'is', 'mr', 'tuple')
>>> list(t)
['my', 'name', 'is', 'mr', 'tuple']

Convert list to tuple:

>>> l = ['my', 'name', 'is', 'mr', 'list']
>>> l
['my', 'name', 'is', 'mr', 'list']
>>> tuple(l)
('my', 'name', 'is', 'mr', 'list')

One solution is to style the left border like so:

li { display: inline; }
li + li {
  border-left: 1px solid;
  margin-left:.5em;
  padding-left:.5em;
}

However, this may not give you desirable results if the entire lists wraps, like it does in your example. I.e. it would give something like:

foo | bar | baz
 | bob | bill
 | judy

There's no direct way to do it yet, unfortunately, but there are a couple indirect ways:

[dt.year for dt in dates.astype(object)]

or

[datetime.datetime.strptime(repr(d), "%Y-%m-%d %H:%M:%S").year for d in dates]

both inspired by the examples here.

Both of these work for me on Numpy 1.6.1. You may need to be a bit more careful with the second one, since the repr() for the datetime64 might have a fraction part after a decimal point.

Try dropping the .value

DateTimeExtended(DateTimeExtended myNewDT)
{
   this.MyDateTime = myNewDT.MyDateTime;
   this.otherdata = myNewDT.otherdata;
}

I'm guessing that you need to assign the Exception to a variable. As shown in the Python 3 tutorial:

def fails():
    x = 1 / 0

try:
    fails()
except Exception as ex:
    print(ex)

To give a brief explanation, as is a pseudo-assignment keyword used in certain compound statements to assign or alias the preceding statement to a variable.

In this case, as assigns the caught exception to a variable allowing for information about the exception to stored and used later, instead of needing to be dealt with immediately. (This is discussed in detail in the Python 3 Language Reference: The try Statement.)

The other compound statement using as is the with statement:

@contextmanager
def opening(filename):
    f = open(filename)
    try:
        yield f
    finally:
        f.close()

with opening(filename) as f:
    # ...read data from f...

Here, with statements are used to wrap the execution of a block with methods defined by context managers. This functions like an extended try...except...finally statement in a neat generator package, and the as statement assigns the generator-produced result from the context manager to a variable for extended use. (This is discussed in detail in the Python 3 Language Reference: The with Statement.)

Finally, as can be used when importing modules, to alias a module to a different (usually shorter) name:

import foo.bar.baz as fbb

This is discussed in detail in the Python 3 Language Reference: The import Statement.

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

You can also use Windows PowerShell with the following command:

if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
    [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
}

Make sure to check that the source does not exist before calling CreateEventSource, otherwise it will throw an exception.

From developer.mozilla.org docs on the String .match() method:

The returned Array has an extra input property, which contains the original string that was parsed. In addition, it has an index property, which represents the zero-based index of the match in the string.

When dealing with a non-global regex (i.e., no g flag on your regex), the value returned by .match() has an index property...all you have to do is access it.

var index = str.match(/regex/).index;

Here is an example showing it working as well:

var str = 'my string here';_x000D_
_x000D_
var index = str.match(/here/).index;_x000D_
_x000D_
alert(index); // <- 10

I have successfully tested this all the way back to IE5.

Thank guys for showing all those examples. I was still having trouble with my contact page on small media screens like below 480px after trying your examples. Bootstrap kept inserting height: auto.

Element Inspector / Devtools will show the height in:

element.style {

}

In my case I was seeing: section#contact.contact-container | 303 x 743 in the browser window.

So the following full-length works to eliminate the issue:

$('section#contact.contact-container').height('');

Here is a code, which makes the same, but with response headers:

import socket
def patch_requests():
    old_readline = socket._fileobject.readline
    if not hasattr(old_readline, 'patched'):
        def new_readline(self, size=-1):
            res = old_readline(self, size)
            print res,
            return res
        new_readline.patched = True
        socket._fileobject.readline = new_readline
patch_requests()

I spent a lot of time searching for this, so I'm leaving it here, if someone needs.

Inserting date in sql

insert

values ('dd-mm-yyyy hh-mm-ss AM');

If suppose we wanted to insert system date

insert
into tablename (timestamp_value)
values (sysdate);

In Case of password also we need to pass one more parameter

redis-cli -h host -p port -a password

   print "hello"

Then you can import hello:

>>> import hello
>>> hello.helloworld()
'hello'
>>>

To group many .py files put them in a folder. Any folder with an __init__.py is considered a module by python and you can call them a package

|-HelloModule
  |_ __init__.py
  |_ hellomodule.py

You can go about with the import statement on your module the usual way.

For more information, see 6.4. Packages.

There is also the Simple Print package, which uses enscript to do the actual printing.

Similar to kenorb's answer, open the palette (ctrl/cmd+shift+p), "Install package", "Simple Print Function"

you MUST install enscript and here is how:

https://github.com/svenax/SublimePrint

Or try this:

apt-get install python-mysqldb

Put from before where, and order_by on last:

$this->db->select('*');
$this->db->from('courses');
$this->db->where('tennant_id',$tennant_id);
$this->db->order_by("UPPER(course_name)","desc");

Or try BINARY:

ORDER BY BINARY course_name DESC;

You should add manually on codeigniter for binary sorting.

And set "course_name" character column.

If sorting is used on a character type column, normally the sort is conducted in a case-insensitive fashion.

What type of structure data in courses table?

If you frustrated you can put into array and return using PHP:

Use natcasesort for order in "natural order": (Reference: http://php.net/manual/en/function.natcasesort.php)

Your array from database as example: $array_db = $result_from_db:

$final_result = natcasesort($array_db);

print_r($final_result);

Like this?

public static void Test()
{
    using (var image = Image.FromFile(@"c:\logo.png"))
    using (var newImage = ScaleImage(image, 300, 400))
    {
        newImage.Save(@"c:\test.png", ImageFormat.Png);
    }
}

public static Image ScaleImage(Image image, int maxWidth, int maxHeight)
{
    var ratioX = (double)maxWidth / image.Width;
    var ratioY = (double)maxHeight / image.Height;
    var ratio = Math.Min(ratioX, ratioY);

    var newWidth = (int)(image.Width * ratio);
    var newHeight = (int)(image.Height * ratio);

    var newImage = new Bitmap(newWidth, newHeight);

    using (var graphics = Graphics.FromImage(newImage))
        graphics.DrawImage(image, 0, 0, newWidth, newHeight);

    return newImage;
}

I know this is old question but...

As Raymond Hettinger said, it should be called while/no_break instead of while/else.
I find it easy to understeand if you look at this snippet.

n = 5
while n > 0:
    print n
    n -= 1
    if n == 2:
        break
if n == 0:
    print n

Now instead of checking condition after while loop we can swap it with else and get rid of that check.

n = 5
while n > 0:
    print n
    n -= 1
    if n == 2:
        break
else:  # read it as "no_break"
    print n

I always read it as while/no_break to understand the code and that syntax makes much more sense to me.

What you do is called a projection. That's when you return only a scalar value that belongs to one entity. You can do this with JPA. See scalar value.

I think in this case, omitting the entity type altogether is possible:

   Query query = em.createNativeQuery(  "select id from users where username = ?");  
   query.setParameter(1, "lt");  
   BigDecimal val = (BigDecimal) query.getSingleResult(); 

Example taken from here.

This is the simplest way to do it.

let total = parseInt(('100,000.00'.replace(',',''))) + parseInt(('500,000.00'.replace(',','')))

I've developed a python package called: parallel_sync

https://pythonhosted.org/parallel_sync/pages/examples.html

Here is a sample code how to use it:

from parallel_sync import rsync
creds = {'user': 'myusername', 'key':'~/.ssh/id_rsa', 'host':'192.168.16.31'}
rsync.upload('/tmp/local_dir', '/tmp/remote_dir', creds=creds)

parallelism by default is 10; you can increase it:

from parallel_sync import rsync
creds = {'user': 'myusername', 'key':'~/.ssh/id_rsa', 'host':'192.168.16.31'}
rsync.upload('/tmp/local_dir', '/tmp/remote_dir', creds=creds, parallelism=20)

however note that ssh typically has the MaxSessions by default set to 10 so to increase it beyond 10, you'll have to modify your ssh settings.

So, there's no way that this works:

window.onload = function(){
  <script language="JavaScript" src="http://jact.atdmt.com/jaction/JavaScriptTest"></script>
};

You can't freely drop HTML into the middle of javascript.

If you have jQuery, you can just use:

$.getScript("http://jact.atdmt.com/jaction/JavaScriptTest")

whenever you want. If you want to make sure the document has finished loading, you can do this:

$(document).ready(function() {
    $.getScript("http://jact.atdmt.com/jaction/JavaScriptTest");
});

In plain javascript, you can load a script dynamically at any time you want to like this:

var tag = document.createElement("script");
tag.src = "http://jact.atdmt.com/jaction/JavaScriptTest";
document.getElementsByTagName("head")[0].appendChild(tag);

$('#content').html('whatever');

If you are using Ruby on Rails there is a squish

> @title = " abc "
 => " abc " 

> @title.squish
 => "abc"
> @title
 => " abc "

> @title.squish!
 => "abc"
> @title
 => "abc" 

If you are using just Ruby you want to use strip

Herein lies the gotcha.. in your case you want to use strip without the bang !

while strip! certainly does return nil if there was no action it still updates the variable so strip! cannot be used inline. If you want to use strip inline you can use the version without the bang !

strip! using multi line approach

> tokens["Title"] = " abc "
 => " abc "
> tokens["Title"].strip!
 => "abc"
> @title = tokens["Title"]
 => "abc"

strip single line approach... YOUR ANSWER

> tokens["Title"] = " abc "
 => " abc "
> @title = tokens["Title"].strip if tokens["Title"].present?
 => "abc"

Already some great answers to this question, however here is a nice snippet that I use regularly to drop rows if they have non-numeric values on some columns:

# Eliminate invalid data from dataframe (see Example below for more context)

num_df = (df.drop(data_columns, axis=1)
         .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))

num_df = num_df[num_df[data_columns].notnull().all(axis=1)]

The way this works is we first drop all the data_columns from the df, and then use a join to put them back in after passing them through pd.to_numeric (with option 'coerce', such that all non-numeric entries are converted to NaN). The result is saved to num_df.

On the second line we use a filter that keeps only rows where all values are not null.

Note that pd.to_numeric is coercing to NaN everything that cannot be converted to a numeric value, so strings that represent numeric values will not be removed. For example '1.25' will be recognized as the numeric value 1.25.

Disclaimer: pd.to_numeric was introduced in pandas version 0.17.0

Example:

In [1]: import pandas as pd

In [2]: df = pd.DataFrame({"item": ["a", "b", "c", "d", "e"],
   ...:                    "a": [1,2,3,"bad",5],
   ...:                    "b":[0.1,0.2,0.3,0.4,0.5]})

In [3]: df
Out[3]: 
     a    b item
0    1  0.1    a
1    2  0.2    b
2    3  0.3    c
3  bad  0.4    d
4    5  0.5    e

In [4]: data_columns = ['a', 'b']

In [5]: num_df = (df
   ...:           .drop(data_columns, axis=1)
   ...:           .join(df[data_columns].apply(pd.to_numeric, errors='coerce')))

In [6]: num_df
Out[6]: 
  item   a    b
0    a   1  0.1
1    b   2  0.2
2    c   3  0.3
3    d NaN  0.4
4    e   5  0.5

In [7]: num_df[num_df[data_columns].notnull().all(axis=1)]
Out[7]: 
  item  a    b
0    a  1  0.1
1    b  2  0.2
2    c  3  0.3
4    e  5  0.5

100% working for me ! After unset elements in array you can use this for re-indexing the array

$result=array_combine(range(1, count($your_array)), array_values($your_array));

I also had the same issue. I changed it to the following and it worked.

Java :

@RequestMapping(value = "/test", method = RequestMethod.GET)

HTML code:

  <form action="<%=request.getContextPath() %>/test" method="GET">
    <input type="submit" value="submit"> 
    </form>

By default if you do not specify http method in a form it uses GET. To use POST method you need specifically state it.

Hope this helps.

In addition to the above answers,

When setting the option number_sections: true in the YAML header:

number_sections: TRUE

RMarkdown will autonumber your sections.

To reference those autonumbered sections simply put the following in your R Markdown file:

[My Section]

Where My Section is the name of the section

This seems to work regardless of the section level:

# My section

## My section

### My section

[EDIT] Years later, I've come back to say: don't do this! See What's wrong with XOR encryption? for details.

A very simple, easy two-way encrytpion is XOR encryption.

1. Come up with a password. Let's have it be mypass.
   
2. Convert the password into binary (according to ASCII). The password becomes 01101101 01111001 01110000 01100001 01110011 01110011.
   
3. Take the message you want to encode. Convert that into binary, also.
   
4. Look at the length of the message. If the message length is 400 bytes, turn the password into a 400 byte string by repeating it over and over again. It would become 01101101 01111001 01110000 01100001 01110011 01110011 01101101 01111001 01110000 01100001 01110011 01110011 01101101 01111001 01110000 01100001 01110011 01110011... (or mypassmypassmypass...)
   
5. XOR the message with the long password.
   
6. Send the result.
   
7. Another time, XOR the encrypted message with the same password (mypassmypassmypass...).
   
8. There's your message!

You could also use a core dump and then examine it with gdb. To get useful information you also need to compile with the -g flag.

Whenever you get the message:

 Segmentation fault (core dumped)

a core file is written into your current directory. And you can examine it with the command

 gdb your_program core_file

The file contains the state of the memory when the program crashed. A core dump can be useful during the deployment of your software.

Make sure your system doesn't set the core dump file size to zero. You can set it to unlimited with:

ulimit -c unlimited

Careful though! that core dumps can become huge.

mod_php means PHP, as an Apache module.

Basically, when loading mod_php as an Apache module, it allows Apache to interpret PHP files (those are interpreted by mod_php).

EDIT : There are (at least) two ways of running PHP, when working with Apache :

• Using CGI : a PHP process is launched by Apache, and it is that PHP process that interprets PHP code -- not Apache itself
• Using PHP as an Apache module (called mod_php) : the PHP interpreter is then kind of "embedded" inside the Apache process : there is no external PHP process -- which means that Apache and PHP can communicate better.

And re-edit, after the comment : using CGI or mod_php is up to you : it's only a matter of configuration of your webserver.

To know which way is currently used on your server, you can check the output of phpinfo() : there should be something indicating whether PHP is running via mod_php (or mod_php5), or via CGI.

You might also want to take a look at the php_sapi_name() function : it returns the type of interface between web server and PHP.

If you check in your Apache's configuration files, when using mod_php, there should be a LoadModule line looking like this :

LoadModule php5_module        modules/libphp5.so

(The file name, on the right, can be different -- on Windows, for example, it should be a .dll)

If you initially installed Node.js with Homebrew, run:

brew update
brew upgrade node
npm install -g npm

Or as a one-liner:

brew update && brew upgrade node && npm install -g npm

A convenient way to change versions is to use nvm:

brew install nvm

To install the latest version of Node.js with nvm:

nvm install node

If you installed via a package, then download the latest version from nodejs.org. See Installing Node.js and updating npm.

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}

I use a decorator to return the result of jsonfiy. I think it is more readable when a view has multiple returns. This does not support returning a tuple like content, status, but I handle returning error statuses with app.errorhandler instead.

import functools
from flask import jsonify

def return_json(f):
    @functools.wraps(f)
    def inner(**kwargs):
        return jsonify(f(**kwargs))

    return inner

@app.route('/test/<arg>')
@return_json
def test(arg):
    if arg == 'list':
        return [1, 2, 3]
    elif arg == 'dict':
        return {'a': 1, 'b': 2}
    elif arg == 'bool':
        return True
    return 'none of them'

The only working solution for me, was to define the data object in the geom_line instead of the base object, ggplot.

Like this:

ggplot() + 
geom_line(data=Data1, aes(x=A, y=B), color='green') + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

instead of

ggplot(data=Data1, aes(x=A, y=B), color='green') + 
geom_line() + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

It depends on what you need to do. You can use replace since you want to replace the value:

select replace(email, '.com', '.org')
from yourtable

Then to UPDATE your table with the new ending, then you would use:

update yourtable
set email = replace(email, '.com', '.org')

You can also expand on this by checking the last 4 characters of the email value:

update yourtable
set email = replace(email, '.com', '.org')
where right(email, 4) = '.com'

However, the issue with replace() is that .com can be will in other locations in the email not just the last one. So you might want to use substring() the following way:

update yourtable
set email = substring(email, 1, len(email) -4)+'.org'
where right(email, 4) = '.com';

See SQL Fiddle with Demo

Using substring() will return the start of the email value, without the final .com and then you concatenate the .org to the end. This prevents the replacement of .com elsewhere in the string.

Alternatively you could use stuff(), which allows you to do both deleting and inserting at the same time:

update yourtable
set email = stuff(email, len(email) - 3, 4, '.org')
where right(email, 4) = '.com';

This will delete 4 characters at the position of the third character before the last one (which is the starting position of the final .com) and insert .org instead.

See SQL Fiddle with Demo for this method as well.

Reading all the answers on this page inspired me a lot.

As you can see from the screenshot below, the output is colored and the error message comes in the used language.

In relation to the original question I'd like to add to the accepted answer by Mohamed Mansour that there is also a way to make this work the other way around:

You can access other extension pages (i.e. options page, popup page) from within the background page/script with the chrome.extension.getViews() call. As described here.

 // overwrite the console object with the right one.
var optionsPage = (  chrome.extension.getViews()  
                 &&  (chrome.extension.getViews().length > 1)  ) 
                ? chrome.extension.getViews()[1] : null;

 // safety precaution.
if (optionsPage) {
  var console = optionsPage.console;
}

As you've noticed, you have no selectivity to your update statement so it is updating your entire table. If you want to update specific rows (ie where the IDs match) you probably want to do a coordinated subquery.

However, since you are using Oracle, it might be easier to create a materialized view for your query table and let Oracle's transaction mechanism handle the details. MVs work exactly like a table for querying semantics, are quite easy to set up, and allow you to specify the refresh interval.

Salam, this answer works only in Chrome, cause IE and FF support color transition.

There is no need to make your HTML elements opacity:0, cause some times they contain text, and no need to double your elements!.

The question with link to an example in jsfiddle needed a small change, that is to put an empty image in .title a like background:url(link to an empty image); same as you put it in .title a:hover but make it empty image, and the code will work.

.title a {
display: block;
width: 340px;
height: 338px;
color: black;
background: url(https://upload.wikimedia.org/wikipedia/commons/5/59/Empty.png) repeat;
/* TRANSISITION */
transition: background 1s;
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
  }
  .title a:hover{   background: transparent;
   background: url(https://lh3.googleusercontent.com/-p1nr1fkWKUo/T0zUp5CLO3I/AAAAAAAAAWg/jDiQ0cUBuKA/s800/red-pattern.png) repeat;
/* TRANSISITION */
transition: background 1s;
-webkit-transition: background 1s;
-moz-transition: background 1s;
-o-transition: background 1s;
}

If you can't use Joda time and you still live in the dark world :) ( Java 5 or lower ) you can enjoy this :

Note: Make sure your date is allready made by the format : dd/MM/YYYY

/**
Make an int Month from a date
*/
public static int getMonthInt(Date date) {

    SimpleDateFormat dateFormat = new SimpleDateFormat("MM");
    return Integer.parseInt(dateFormat.format(date));
}

/**
Make an int Year from a date
*/
public static int getYearInt(Date date) {

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy");
    return Integer.parseInt(dateFormat.format(date));
}

For longitudes use: Decimal(9,6), and latitudes use: Decimal(8,6)

If you're not used to precision and scale parameters, here's a format string visual:

###.###### and ##.######

You can now use the ExpectedException attributes, e.g.

[Test]
[ExpectedException(typeof(InvalidOperationException), 
 ExpectedMessage="You can't do that!"]
public void MethodA_WithNull_ThrowsInvalidOperationException()
{
    MethodA(null);
}

Here is my little utility helper for splitting paths int file, path tokens:

import os    
# usage: file, path = splitPath(s)
def splitPath(s):
    f = os.path.basename(s)
    p = s[:-(len(f))-1]
    return f, p

Reload the current page:
F5
or
CTRL + R


Reload the current page, ignoring cached content (i.e. JavaScript files, images, etc.):
SHIFT + F5
or
CTRL + F5
or
CTRL + SHIFT + R

I know this is kind of old question, but I thought maybe someone like my trick. Especially since this solution not limited to a specific number of items.

# Convert to an array
_ITEMS=($(echo "12|23|11" | tr '|' '\n'))

# Output array items
for _ITEM in "${_ITEMS[@]}"; do
  echo "Item: ${_ITEM}"
done

The output will be:

Item: 12
Item: 23
Item: 11

What would be wrong with doing;

<div className="" key={index}>
   {i.title}
</div>

[/*Use IIFE */]

{(function () {
     if (child.children && child.children.length !== 0) {
     let menu = createMenu(child.children);
     console.log("nested menu", menu);
     return menu;
   }
 })()}

The page that appears after clicking, just write into it.

  componentDidMount() {
    window.scrollTo(0, 0);
  } 

if(JSON.stringify(Object.keys(pcOrGroup).sort()) === JSON.stringify(Object.keys(orGroup)).sort())
{
    return true;
}

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

This is similar to qntmfred's solution, but using a direct table dump. This option is slightly faster (see BCP docs):

to export:

bcp "[MyDatabase].dbo.Customer " out "Customer.bcp" -N -S localhost -T -E

to import:

bcp [MyDatabase].dbo.Customer in "Customer.bcp" -N -S localhost -T -E -b 10000

Use:

if (function_exists('curl_file_create')) { // php 5.5+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

You can also refer:

http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);

when you bind localhost or 127.0.0.1, it means you can only connect to your service from local.

you cannot bind 10.0.0.1 because it not belong to you, you can only bind ip owned by your computer

you can bind 0.0.0.0 because it means all ip on your computer, so any ip can connect to your service if they can connect to any of your ip

Exchange rate from Euro to NOK on the first of January 2016:

=INDEX(GOOGLEFINANCE("CURRENCY:EURNOK"; "close"; DATE(2016;1;1)); 2; 2)

The INDEX() function is used because GOOGLEFINANCE() function actually prints out in 4 separate cells (2x2) when you call it with these arguments, with it the result will only be one cell.

To get activity state data stored in onCreate(), first you have to save data in savedInstanceState by overriding SaveInstanceState(Bundle savedInstanceState) method.

When activity destroy SaveInstanceState(Bundle savedInstanceState) method gets called and there you save data you want to save. And you get same in onCreate() when activity restart.(savedInstanceState wont be null since you have saved some data in it before activity get destroyed)

When on Ubuntu 18.04 using Python3.6 I have solved the problem doing both:

with open(filename, encoding="utf-8") as lines:

and if you are running the tool as command line:

export LC_ALL=C.UTF-8

Note that if you are in Python2.7 you have do to handle this differently. First you have to set the default encoding:

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

and then to load the file you must use io.open to set the encoding:

import io
with io.open(filename, 'r', encoding='utf-8') as lines:

You still need to export the env

export LC_ALL=C.UTF-8

The DictWriter() class expects dictionaries for each row. If all you wanted to do was write an initial header, use a regular csv.writer() and pass in a simple row for the header:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.writer(outcsv)
    writer.writerow(["Date", "temperature 1", "Temperature 2"])

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row + [0.0] for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows(row[:1] + [0.0] + row[1:] for row in reader)

The alternative would be to generate dictionaries when copying across your data:

import csv

with open('combined_file.csv', 'w', newline='') as outcsv:
    writer = csv.DictWriter(outcsv, fieldnames = ["Date", "temperature 1", "Temperature 2"])
    writer.writeheader()

    with open('t1.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': row[1], 'temperature 2': 0.0} for row in reader)

    with open('t2.csv', 'r', newline='') as incsv:
        reader = csv.reader(incsv)
        writer.writerows({'Date': row[0], 'temperature 1': 0.0, 'temperature 2': row[1]} for row in reader)

Here is another way to do this - using the API function WideCharToMultiByte:

Option Explicit

Private Declare Function WideCharToMultiByte Lib "kernel32.dll" ( _
  ByVal CodePage As Long, _
  ByVal dwFlags As Long, _
  ByVal lpWideCharStr As Long, _
  ByVal cchWideChar As Long, _
  ByVal lpMultiByteStr As Long, _
  ByVal cbMultiByte As Long, _
  ByVal lpDefaultChar As Long, _
  ByVal lpUsedDefaultChar As Long) As Long

Private Sub getUtf8(ByRef s As String, ByRef b() As Byte)
Const CP_UTF8 As Long = 65001
Dim len_s As Long
Dim ptr_s As Long
Dim size As Long
  Erase b
  len_s = Len(s)
  If len_s = 0 Then _
    Err.Raise 30030, , "Len(WideChars) = 0"
  ptr_s = StrPtr(s)
  size = WideCharToMultiByte(CP_UTF8, 0, ptr_s, len_s, 0, 0, 0, 0)
  If size = 0 Then _
    Err.Raise 30030, , "WideCharToMultiByte() = 0"
  ReDim b(0 To size - 1)
  If WideCharToMultiByte(CP_UTF8, 0, ptr_s, len_s, VarPtr(b(0)), size, 0, 0) = 0 Then _
    Err.Raise 30030, , "WideCharToMultiByte(" & Format$(size) & ") = 0"
End Sub

Public Sub writeUtf()
Dim file As Integer
Dim s As String
Dim b() As Byte
  s = "äöüßµ@€|~{}[]²³\ .." & _
    " OMEGA" & ChrW$(937) & ", SIGMA" & ChrW$(931) & _
    ", alpha" & ChrW$(945) & ", beta" & ChrW$(946) & ", pi" & ChrW$(960) & vbCrLf
  file = FreeFile
  Open "C:\Temp\TestUtf8.txt" For Binary Access Write Lock Read Write As #file
  getUtf8 s, b
  Put #file, , b
  Close #file
End Sub

I think the best way is to keep the MVVM principle clean, so basically you must use the Messenger Class provided with the MVVM Light and here is how to use it:

in your viewmodel(exampleViewModel.cs):write the following

 Messenger.Default.Send<string>("focus", "DoFocus");

now in your View.cs(not the XAML the view.xaml.cs) write the following in the constructor

 public MyView()
        {
            InitializeComponent();

            Messenger.Default.Register<string>(this, "DoFocus", doFocus);
        }
        public void doFocus(string msg)
        {
            if (msg == "focus")
                this.txtcode.Focus();
        }

that method owrks just fine and with less code and maintaining MVVM standards

Does m really need to be a data.frame() or will a matrix() suffice?

m <- matrix(0, ncol = 30, nrow = 2)

You can wrap a data.frame() around that if you need to:

m <- data.frame(m)

or all in one line: m <- data.frame(matrix(0, ncol = 30, nrow = 2))

Here's an example of how you could implement a list view:

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //We have our list view
    final ListView dynamic = findViewById(R.id.dynamic);

    //Create an array of elements
    final ArrayList<String> classes = new ArrayList<>();
    classes.add("Data Structures");
    classes.add("Assembly Language");
    classes.add("Calculus 3");
    classes.add("Switching Systems");
    classes.add("Analysis Tools");

    //Create adapter for ArrayList
    final ArrayAdapter<String> adapter = new ArrayAdapter<>(this,android.R.layout.simple_list_item_1, classes);

    //Insert Adapter into List
    dynamic.setAdapter(adapter);

    //set click functionality for each list item
    dynamic.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Log.i("User clicked ", classes.get(position));
        }
    });



}

A web service endpoint is the URL that another program would use to communicate with your program. To see the WSDL you add ?wsdl to the web service endpoint URL.

Web services are for program-to-program interaction, while web pages are for program-to-human interaction.

So: Endpoint is: http://www.blah.com/myproject/webservice/webmethod

Therefore, WSDL is: http://www.blah.com/myproject/webservice/webmethod?wsdl

To expand further on the elements of a WSDL, I always find it helpful to compare them to code:

A WSDL has 2 portions (physical & abstract).

Physical Portion:

Definitions - variables - ex: myVar, x, y, etc.

Types - data types - ex: int, double, String, myObjectType

Operations - methods/functions - ex: myMethod(), myFunction(), etc.

Messages - method/function input parameters & return types

• ex: public myObjectType myMethod(String myVar)

Porttypes - classes (i.e. they are a container for operations) - ex: MyClass{}, etc.

Abstract Portion:

Binding - these connect to the porttypes and define the chosen protocol for communicating with this web service. - a protocol is a form of communication (so text/SMS, vs. phone vs. email, etc.).

Service - this lists the address where another program can find your web service (i.e. your endpoint).

Also, I'm using following solution:

$('a[data-toggle="tab"]').on('click', function(){
  if ($(this).parent('li').hasClass('disabled')) {
    return false;
  };
});

Now you just adding class 'disabled' to the parent li and tab doesn't work and become gray.
