Order Collection Limit :

$orderCollection = Mage::getResourceModel('sales/order_collection'); 
$orderCollection->getSelect()->limit(10);

foreach ($orderCollection->getItems() as $order) :
   $orderModel = Mage::getModel('sales/order');
   $order =   $orderModel->load($order['entity_id']);
   echo $order->getId().'<br>'; 
endforeach; 

I had the same problem and I just tried using the following as a workaround. Seems to work so far. You can even create a dummy template that just contains references to all those static assets.

{% stylesheets
    output='assets/fonts/glyphicons-halflings-regular.ttf'
    'bundles/bootstrap/fonts/glyphicons-halflings-regular.ttf'
%}{% endstylesheets %}

Notice the omission of any output which means nothing shows up on the template. When I run assetic:dump the files are copied over to the desired location and the css includes work as expected.

I don't think there is any kind of bug in the PagerAdapter. The problem is that understanding how it works is a little complex. Looking at the solutions explained here, there is a misunderstanding and therefore a poor usage of instantiated views from my point of view.

The last few days I have been working with PagerAdapter and ViewPager, and I found the following:

The notifyDataSetChanged() method on the PagerAdapter will only notify the ViewPager that the underlying pages have changed. For example, if you have created/deleted pages dynamically (adding or removing items from your list) the ViewPager should take care of that. In this case I think that the ViewPager determines if a new view should be deleted or instantiated using the getItemPosition() and getCount() methods.

I think that ViewPager, after a notifyDataSetChanged() call takes it's child views and checks their position with the getItemPosition(). If for a child view this method returns POSITION_NONE, the ViewPager understands that the view has been deleted, calling the destroyItem(), and removing this view.

In this way, overriding getItemPosition() to always return POSITION_NONE is completely wrong if you only want to update the content of the pages, because the previously created views will be destroyed and new ones will be created every time you call notifyDatasetChanged(). It may seem to be not so wrong just for a few TextViews, but when you have complex views, like ListViews populated from a database, this can be a real problem and a waste of resources.

So there are several approaches to efficiently change the content of a view without having to remove and instantiate the view again. It depends on the problem you want to solve. My approach is to use the setTag() method for any instantiated view in the instantiateItem() method. So when you want to change the data or invalidate the view that you need, you can call the findViewWithTag() method on the ViewPager to retrieve the previously instantiated view and modify/use it as you want without having to delete/create a new view each time you want to update some value.

Imagine for example that you have 100 pages with 100 TextViews and you only want to update one value periodically. With the approaches explained before, this means you are removing and instantiating 100 TextViews on each update. It does not make sense...

I was able to use the name attribute that you described in your example for the loop I am working on and it worked, perhaps because I created unique ids? I'm still considering whether I should switch to an editor template instead as mentioned in the links in another answer.

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "true", new {Name = item.Description.QuestionId, id = string.Format("CBY{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" }) Yes

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "false", new { Name = item.Description.QuestionId, id = string.Format("CBN{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" } ) No

Solution:

http://jsfiddle.net/VR2hP/

ul li:before {    
    font-family: 'FontAwesome';
    content: '\f067';
    margin:0 5px 0 -15px;
    color: #f00;
}

Here's a blog post which explains this technique in-depth.

Just in case, someone is looking for a sql LIKE kind of query for a key that holds an Array of Strings instead of a String, here it is:

db.users.find({"name": {$in: [/.*m.*/]}})

This solution will leave all the computed javascript and add the important tag into the element: You can do (Ex if you need to set the width with the important tag)

$('exampleDiv').css('width', '');
//This will remove the width of the item
var styles = $('exampleDiv').attr('style');
//This will contain all styles in your item
//ex: height:auto; display:block;
styles += 'width: 200px !important;'
//This will add the width to the previous styles
//ex: height:auto; display:block; width: 200px !important;
$('exampleDiv').attr('style', styles);
//This will add all previous styles to your item

            str += 'M';
        return str
    } else if (d == 1)

I think easy way to disable button is :data => { disable_with: "Saving.." } This will submit a form and then make a button disable, Also it won't disable button if you have any validations like required = 'required'.

Pre-Java 8 you should use:

tourists.removeAll(Collections.singleton(null));

Post-Java 8 use:

tourists.removeIf(Objects::isNull);

The reason here is time complexity. The problem with arrays is that a remove operation can take O(n) time to complete. Really in Java this is an array copy of the remaining elements being moved to replace the empty spot. Many other solutions offered here will trigger this issue. The former is technically O(n*m) where m is 1 because it's a singleton null: so O(n)

You should removeAll of the singleton, internally it does a batchRemove() which has a read position and a write position. And iterates the list. When it hits a null, it simply iterates the read position by 1. When they are the same it passes, when they are different it keeps moving along copying the values. Then at the end it trims to size.

It effectively does this internally:

public static <E> void removeNulls(ArrayList<E> list) {
    int size = list.size();
    int read = 0;
    int write = 0;
    for (; read < size; read++) {
        E element = list.get(read);
        if (element == null) continue;
        if (read != write) list.set(write, element);
        write++;
    }
    if (write != size) {
        list.subList(write, size).clear();
    }
}

Which you can explicitly see is an O(n) operation.

The only thing that could ever be faster is if you iterated the list from both ends, and when you found a null, you set its value equal to the value you found at the end, and decremented that value. And iterated until the two values matched. You'd mess up the order, but would vastly reduce the number of values you set vs. ones you left alone. Which is a good method to know but won't help much here as .set() is basically free, but that form of delete is a useful tool for your belt.

for (Iterator<Tourist> itr = tourists.iterator(); itr.hasNext();) {
      if (itr.next() == null) { itr.remove(); }
 }

While this seems reasonable enough, the .remove() on the iterator internally calls:

ArrayList.this.remove(lastRet);

Which is again the O(n) operation within the remove. It does an System.arraycopy() which is again not what you want, if you care about speed. This makes it n^2.

There's also:

while(tourists.remove(null));

Which is O(m*n^2). Here we not only iterate the list. We reiterate the entire list, each time we match the null. Then we do n/2 (average) operations to do the System.arraycopy() to perform the remove. You could quite literally, sort the entire collection between items with values and items with null values and trim the ending in less time. In fact, that's true for all the broken ones. At least in theory, the actual system.arraycopy isn't actually an N operation in practice. In theory, theory and practice are the same thing; in practice they aren't.

just use stoi/stol/stoll for example:

std::cout << std::stol("fffefffe", nullptr, 16) << std::endl;

output: 4294901758

mkdir -p gives you an error if the file already exists:

$ touch /tmp/foo
$ mkdir -p /tmp/foo
mkdir: cannot create directory `/tmp/foo': File exists

So a refinement to the previous suggestions would be to re-raise the exception if os.path.isdir returns False (when checking for errno.EEXIST).

(Update) See also this highly similar question; I agree with the accepted answer (and caveats) except I would recommend os.path.isdir instead of os.path.exists.

(Update) Per a suggestion in the comments, the full function would look like:

import os
def mkdirp(directory):
    if not os.path.isdir(directory):
        os.makedirs(directory) 

A simple working code to download a file with SSH.NET library is:

using (Stream fileStream = File.Create(@"C:\target\local\path\file.zip"))
{
    sftp.DownloadFile("/source/remote/path/file.zip", fileStream);
}

See also Downloading a directory using SSH.NET SFTP in C#.

To explain, why your code does not work:

The second parameter of SftpClient.DownloadFile is a stream to write a downloaded contents to.

You are passing in a read stream instead of a write stream. And moreover the path you are opening read stream with is a remote path, what cannot work with File class operating on local files only.

Just discard the File.OpenRead line and use a result of previous File.OpenWrite call instead (that you are not using at all now):

Stream file1 = File.OpenWrite(localFileName);

sftp.DownloadFile(file.FullName, file1);

Or even better, use File.Create to discard any previous contents that the local file may have.

I'm not sure if your localFileName is supposed to hold full path, or just file name. So you may need to add a path too, if necessary (combine localFileName with sDir?)

Based on the fact that the request isn't sent on the default port 80/443 this Ajax call is automatically considered a cross-origin resource (CORS) request, which in other words means that the request automatically issues an OPTIONS request which checks for CORS headers on the server's/servlet's side.

This happens even if you set

crossOrigin: false;

or even if you ommit it.

The reason is simply that localhost != localhost:57124. Try sending it only to localhost without the port - it will fail, because the requested target won't be reachable, however notice that if the domain names are equal the request is sent without the OPTIONS request before POST.

Simple script to remove given tag from both local and origin locations. With a check if tag really exists.

if [ $(git tag -l "$1") ]; then
    git tag --delete  $1
    git push --delete origin $1

    echo done.
else
    echo tag named "$1" was not found
fi

How to use:

• Create shell script file (e.g. git-tag-purge.sh) and paste content.
• chmod your script file to make it executable.
• Make the script globally available
• cd to your git project
• Call script (e.g.

  $>git-tag-purge.sh tag_name

  )

@Query("SELECT DISTINCT name FROM people WHERE name NOT IN (:names)")
List<String> findNonReferencedNames(@Param("names") List<String> names);

There's no reason for the {} command not to work. The semi-obvious questions are:

1. You are sure that the product is actually installed! There's something in ARP/Programs&Features.

2. The original install is in fact visible in the current context. It looks as if it might have been a per-user install, and if you are logged in as somebody else now then it won't know about it - you'd need to log in under the same account as the original install.

3. If the \windows\installer directory was damaged the cached file would be missing, and that's used to do the uninstall.

You can use alert(arrayObj.toSource());

    public static string Serialize(object dataToSerialize)
    {
        if(dataToSerialize==null) return null;

        using (StringWriter stringwriter = new System.IO.StringWriter())
        {
            var serializer = new XmlSerializer(dataToSerialize.GetType());
            serializer.Serialize(stringwriter, dataToSerialize);
            return stringwriter.ToString();
        }
    }

    public static T Deserialize<T>(string xmlText)
    {
        if(String.IsNullOrWhiteSpace(xmlText)) return default(T);

        using (StringReader stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(T));
            return (T)serializer.Deserialize(stringReader);
        }
    }

You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.

select t2.* 
from t1 join t2 
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000

I just wanted to mention that one can get the detailed GC log with the

-XX:+PrintGCDetails 

parameter. Then you see the PSYoungGen or PSPermGen output like in the answer.

Also -Xloggc:gc.log seems to generate the same output like -verbose:gc but you can specify an output file in the first.

Example usage:

java -Xloggc:./memory.log -XX:+PrintGCDetails Memory

To visualize the data better you can try gcviewer (a more recent version can be found on github).

Take care to write the parameters correctly, I forgot the "+" and my JBoss would not start up, without any error message!

What is wrong here is that your session management configuration is set to close session when you commit transaction. Check if you have something like:

<property name="current_session_context_class">thread</property>

in your configuration.

In order to overcome this problem you could change the configuration of session factory or open another session and only than ask for those lazy loaded objects. But what I would suggest here is to initialize this lazy collection in getModelByModelGroup itself and call:

Hibernate.initialize(subProcessModel.getElement());

when you are still in active session.

And one last thing. A friendly advice. You have something like this in your method:

for (Model m : modelList) {
    if (m.getModelType().getId() == 3) {
        model = m;
        break;
    }
}

Please insted of this code just filter those models with type id equal to 3 in the query statement just couple of lines above.

By default login failed error message is nothing but a client user connection has been refused by the server due to mismatch of login credentials. First task you might check is to see whether that user has relevant privileges on that SQL Server instance and relevant database too, thats good. Obviously if the necessary prvileges are not been set then you need to fix that issue by granting relevant privileges for that user login.

Althought if that user has relevant grants on database & server if the Server encounters any credential issues for that login then it will prevent in granting the authentication back to SQL Server, the client will get the following error message:

Msg 18456, Level 14, State 1, Server <ServerName>, Line 1
Login failed for user '<Name>'

Ok now what, by looking at the error message you feel like this is non-descriptive to understand the Level & state. By default the Operating System error will show 'State' as 1 regardless of nature of the issues in authenticating the login. So to investigate further you need to look at relevant SQL Server instance error log too for more information on Severity & state of this error. You might look into a corresponding entry in log as:

2007-05-17 00:12:00.34 Logon     Error: 18456, Severity: 14, State: 8.
or

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

As defined above the Severity & State columns on the error are key to find the accurate reflection for the source of the problem. On the above error number 8 for state indicates authentication failure due to password mismatch. Books online refers: By default, user-defined messages of severity lower than 19 are not sent to the Microsoft Windows application log when they occur. User-defined messages of severity lower than 19 therefore do not trigger SQL Server Agent alerts.

Sung Lee, Program Manager in SQL Server Protocols (Dev.team) has outlined further information on Error state description:The common error states and their descriptions are provided in the following table:

ERROR STATE       ERROR DESCRIPTION
------------------------------------------------------------------------------
2 and 5           Invalid userid
6                 Attempt to use a Windows login name with SQL Authentication
7                 Login disabled and password mismatch
8                 Password mismatch
9                 Invalid password
11 and 12         Valid login but server access failure
13                SQL Server service paused
18                Change password required


Well I'm not finished yet, what would you do in case of error:

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

You can see there is no severity or state level defined from that SQL Server instance's error log. So the next troubleshooting option is to look at the Event Viewer's security log [edit because screen shot is missing but you get the

idea, look in the event log for interesting events].

Zupa did a great job explaining closures with 'use' and the difference between EarlyBinding and Referencing the variables that are 'used'.

So I made a code example with early binding of a variable (= copying):

<?php

$a = 1;
$b = 2;

$closureExampleEarlyBinding = function() use ($a, $b){
    $a++;
    $b++;
    echo "Inside \$closureExampleEarlyBinding() \$a = ".$a."<br />";
    echo "Inside \$closureExampleEarlyBinding() \$b = ".$b."<br />";    
};

echo "Before executing \$closureExampleEarlyBinding() \$a = ".$a."<br />";
echo "Before executing \$closureExampleEarlyBinding() \$b = ".$b."<br />";  

$closureExampleEarlyBinding();

echo "After executing \$closureExampleEarlyBinding() \$a = ".$a."<br />";
echo "After executing \$closureExampleEarlyBinding() \$b = ".$b."<br />";

/* this will output:
Before executing $closureExampleEarlyBinding() $a = 1
Before executing $closureExampleEarlyBinding() $b = 2
Inside $closureExampleEarlyBinding() $a = 2
Inside $closureExampleEarlyBinding() $b = 3
After executing $closureExampleEarlyBinding() $a = 1
After executing $closureExampleEarlyBinding() $b = 2
*/

?>

Example with referencing a variable (notice the '&' character before variable);

<?php

$a = 1;
$b = 2;

$closureExampleReferencing = function() use (&$a, &$b){
    $a++;
    $b++;
    echo "Inside \$closureExampleReferencing() \$a = ".$a."<br />";
    echo "Inside \$closureExampleReferencing() \$b = ".$b."<br />"; 
};

echo "Before executing \$closureExampleReferencing() \$a = ".$a."<br />";
echo "Before executing \$closureExampleReferencing() \$b = ".$b."<br />";   

$closureExampleReferencing();

echo "After executing \$closureExampleReferencing() \$a = ".$a."<br />";
echo "After executing \$closureExampleReferencing() \$b = ".$b."<br />";    

/* this will output:
Before executing $closureExampleReferencing() $a = 1
Before executing $closureExampleReferencing() $b = 2
Inside $closureExampleReferencing() $a = 2
Inside $closureExampleReferencing() $b = 3
After executing $closureExampleReferencing() $a = 2
After executing $closureExampleReferencing() $b = 3
*/

?>

Short answer:

ALTER SCHEMA new_schema TRANSFER old_schema.table_name

I can confirm that the data in the table remains intact, which is probably quite important :)

Long answer as per MSDN docs,

ALTER SCHEMA schema_name 
   TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]

If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.

With the Ranges library that is coming in C++20, you can use

ranges::sort(arr);

directly, where arr is a builtin array.

This error comes when you only have JRE installed instead of JDK in your JAVA_HOME variable. Unfortunately, you cannot have both of them installed in the same variable so you just need to overwrite the variable with new JDK installation path.

The process should be the same as the way you had JRE installed

Some people have had issues with it, and disabled it, but as a general rule, if it aint broke...

It depends. See the MySQL Performance Blog post on this subject: To SQL_CALC_FOUND_ROWS or not to SQL_CALC_FOUND_ROWS?

Just a quick summary: Peter says that it depends on your indexes and other factors. Many of the comments to the post seem to say that SQL_CALC_FOUND_ROWS is almost always slower - sometimes up to 10x slower - than running two queries.

Use stream_get_line: stream_get_line — Gets line from stream resource up to a given delimiter Source: http://php.net/manual/en/function.stream-get-line.php

By far the simplest way that I've found:

@Override
public String toString() {
    return this.label;           
}

Now you can stick any object in your spinner, and it will display the specified label.

You need to set up the parent-child relationship between your components. The problem is that you might simply inject the child components in the constructor of the parent component and store it in a local variable. Instead, you should declare the child components in your parent component by using the @ViewChild property declarator. This is how your parent component should look like:

import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { ListComponent } from './list.component';
import { DetailComponent } from './detail.component';

@Component({
  selector: 'app-component',
  template: '<list-component></list-component><detail-component></detail-component>',
  directives: [ListComponent, DetailComponent]
})
class AppComponent implements AfterViewInit {
  @ViewChild(ListComponent) listComponent:ListComponent;
  @ViewChild(DetailComponent) detailComponent: DetailComponent;

  ngAfterViewInit() {
    // afther this point the children are set, so you can use them
    this.detailComponent.doSomething();
  }
}

https://angular.io/docs/ts/latest/api/core/index/ViewChild-var.html

https://angular.io/docs/ts/latest/cookbook/component-communication.html#parent-to-view-child

Beware, the child component will not be available in the constructor of the parent component, just after the ngAfterViewInit lifecycle hook is called. To catch this hook simple implement the AfterViewInit interface in you parent class the same way you would do with OnInit.

But, there are other property declarators as explained in this blog note: http://blog.mgechev.com/2016/01/23/angular2-viewchildren-contentchildren-difference-viewproviders/

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

If you install the composer as global on Ubuntu, you just need to find the composer location.

Use command

type composer

or

where composer

For Mac users, use command:

which composer

and then just remove the folder using rm command.

While the above most upvoted answers definitely work, I'd suggest using a slightly different approach in some cases.

If your class has multiple properties with always the same attribute and you want to get those attributes sorted into a dictionary, here is how:

var dict = typeof(Book).GetProperties().ToDictionary(p => p.Name, p => p.GetCustomAttributes(typeof(AuthorName), false).Select(a => (AuthorName)a).FirstOrDefault());

This still uses cast but ensures that the cast will always work as you will only get the custom attributes of the type "AuthorName". If you had multiple Attributes above answers would get a cast exception.

There is a more concise and intuitive way to add days to php date. Don't get me wrong, those php expressions are great, but you always have to google how to treat them. I miss auto-completion facility for that.

Here is how I like to handle those cases:

(new Future(
    new DateTimeFromISO8601String('2014-11-21T06:04:31.321987+00:00'),
    new OneDay()
))
    ->value();

For me, it's way more intuitive and autocompletion works out of the box. No need to google for the solution each time.

As a nice bonus, you don't have to worry about formatting the resulting value, it's already is ISO8601 format.

This is meringue library, there are more examples here.

It's perfectly OK doing it that way, but unless you need to use a closure or return the function I'd probably put in the module level. I imagine in the second code example you mean:

...
some_data = method_b() # not some_data = method_b

otherwise, some_data will be the function.

Having it at the module level will allow other functions to use method_b() and if you're using something like Sphinx (and autodoc) for documentation, it will allow you to document method_b as well.

You also may want to consider just putting the functionality in two methods in a class if you're doing something that can be representable by an object. This contains logic well too if that's all you're looking for.

These two CSS properties can be used to hide the scrollbars:

overflow-y: hidden; // hide vertical
overflow-x: hidden; // hide horizontal

The size attribute works, as well

<input size="25" type="text">

Also constructor based initialisation will not work as intended whenever some kind of proxying or remoting is involved.

The ct will get called whenever an EJB gets deserialized, and whenever a new proxy gets created for it...

  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  //var values = rows.getValues();

  var Names = sheet.getRange("A2:A7");
  var Name = [
    Names.getCell(1, 1).getValue(),
    Names.getCell(2, 1).getValue(),
    .....
    Names.getCell(5, 1).getValue()]

You can define arrays simply as follows, instead of allocating and then assigning.

var arr = [1,2,3,5]

Your initial error was because of the following line, and ones like it

var Name[0] = Name_cell.getValue(); 

Since Name is already defined and you are assigning the values to its elements, you should skip the var, so just

Name[0] = Name_cell.getValue();

Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.

You can use the before or after pseudo-element and apply some CSS to it. There are various ways. You can add both before and after, and rotate and position each of them to form one of the bars. An easier solution is adding two borders to just the before element and rotate it using transform: rotate.

Scroll down for a different solution that uses an actual element instead of the pseuso elements

In this case, I've added the arrows as bullets in a list and used em sizes to make them size properly with the font of the list.

ul {_x000D_
    list-style: none;_x000D_
}_x000D_
_x000D_
ul.big {_x000D_
    list-style: none;_x000D_
    font-size: 300%_x000D_
}_x000D_
_x000D_
li::before {_x000D_
    position: relative;_x000D_
    /* top: 3pt; Uncomment this to lower the icons as requested in comments*/_x000D_
    content: "";_x000D_
    display: inline-block;_x000D_
    /* By using an em scale, the arrows will size with the font */_x000D_
    width: 0.4em;_x000D_
    height: 0.4em;_x000D_
    border-right: 0.2em solid black;_x000D_
    border-top: 0.2em solid black;_x000D_
    transform: rotate(45deg);_x000D_
    margin-right: 0.5em;_x000D_
}_x000D_
_x000D_
/* Change color */_x000D_
li:hover {_x000D_
  color: red; /* For the text */_x000D_
}_x000D_
li:hover::before {_x000D_
  border-color: red; /* For the arrow (which is a border) */_x000D_
}

<ul>_x000D_
    <li>Item1</li>_x000D_
    <li>Item2</li>_x000D_
    <li>Item3</li>_x000D_
    <li>Item4</li>_x000D_
</ul>_x000D_
_x000D_
<ul class="big">_x000D_
    <li>Item1</li>_x000D_
    <li>Item2</li>_x000D_
    <li>Item3</li>_x000D_
    <li>Item4</li>_x000D_
</ul>

Of course you don't need to use before or after, you can apply the same trick to a normal element as well. For the list above it is convenient, because you don't need additional markup. But sometimes you may want (or need) the markup anyway. You can use a div or span for that, and I've even seen people even recycle the i element for 'icons'. So that markup could look like below. Whether using <i> for this is right is debatable, but you can use span for this as well to be on the safe side.

/* Default icon formatting */_x000D_
i {_x000D_
  display: inline-block;_x000D_
  font-style: normal;_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
/* Additional formatting for arrow icon */_x000D_
i.arrow {_x000D_
    /* top: 2pt; Uncomment this to lower the icons as requested in comments*/_x000D_
    width: 0.4em;_x000D_
    height: 0.4em;_x000D_
    border-right: 0.2em solid black;_x000D_
    border-top: 0.2em solid black;_x000D_
    transform: rotate(45deg);_x000D_
}

And so you can have an <i class="arrow" title="arrow icon"></i> in your text._x000D_
This arrow is <i class="arrow" title="arrow icon"></i> used to be deliberately lowered slightly on request._x000D_
I removed that for the general public <i class="arrow" title="arrow icon"></i> but you can uncomment the line with 'top' <i class="arrow" title="arrow icon"></i> to restore that effect.

If you seek more inspiration, make sure to check out this awesome library of pure CSS icons by Nicolas Gallagher. :)

Edit the tty configuration in /etc/init/tty*.conf with a shellscript as a parameter :

(...)
exec /sbin/getty -n -l  theInputScript.sh -8 38400 tty1
(...)

This is assuming that we're editing tty1 and the script that reads input is theInputScript.sh.

A word of warning this script is run as root, so when you are inputing stuff to it you have root priviliges. Also append a path to the location of the script.

Important: the script when it finishes, has to invoke the /sbin/login otherwise you wont be able to login in the terminal.

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

if it is window7(like mine), without administrative rights cannot write a file at C: drive

just give another folder in log4j.properties file

Set the name of the file

log4j.appender.FILE.File=C:\server\log.out you can see with notepad++

    <table>
      <thead>
        <tr><th>title</th><th>price><th>number</th></tr>
      </thead>
      <tbody>
<?php
  foreach ($shop as $row) {
    echo '<tr>';
    foreach ($row as $item) {
      echo "<td>{$item}</td>";
    }
    echo '</tr>';
  }
?>
      </tbody>
    </table>

Yet another solution using the previous suggestions, but with the "correct" parse error from argparse:

def str2bool(v):
    if isinstance(v, bool):
       return v
    if v.lower() in ('yes', 'true', 't', 'y', '1'):
        return True
    elif v.lower() in ('no', 'false', 'f', 'n', '0'):
        return False
    else:
        raise argparse.ArgumentTypeError('Boolean value expected.')

This is very useful to make switches with default values; for instance

parser.add_argument("--nice", type=str2bool, nargs='?',
                        const=True, default=False,
                        help="Activate nice mode.")

allows me to use:

script --nice
script --nice <bool>

and still use a default value (specific to the user settings). One (indirectly related) downside with that approach is that the 'nargs' might catch a positional argument -- see this related question and this argparse bug report.

using System;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        int[] numbers = { 3, 9, 5 };
        int biggestNumber = numbers.Max();
        Console.WriteLine(biggestNumber);
        Console.ReadLine();
    }
}

You can use model.save(filepath) to save a Keras model into a single HDF5 file which will contain:

• the architecture of the model, allowing to re-create the model.
• the weights of the model.
• the training configuration (loss, optimizer)
• the state of the optimizer, allowing to resume training exactly where you left off.

In your Python code probable the last line should be:

model.save("m.hdf5")

This allows you to save the entirety of the state of a model in a single file. Saved models can be reinstantiated via keras.models.load_model().

The model returned by load_model() is a compiled model ready to be used (unless the saved model was never compiled in the first place).

model.save() arguments:

• filepath: String, path to the file to save the weights to.
• overwrite: Whether to silently overwrite any existing file at the target location, or provide the user with a manual prompt.
• include_optimizer: If True, save optimizer's state together.

What exactly IS unit testing? Is it built into code or run as separate programs? Or something else?

From MSDN: The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect.

Essentially, you are writing small bits of code to test the individual bits of your code. In the .net world, you would run these small bits of code using something like NUnit or MBunit or even the built in testing tools in visual studio. In Java you might use JUnit. Essentially the test runners will build your project, load and execute the unit tests and then let you know if they pass or fail.

How do you do it?

Well it's easier said than done to unit test. It takes quite a bit of practice to get good at it. You need to structure your code in a way that makes it easy to unit test to make your tests effective.

When should it be done? Are there times or projects not to do it? Is everything unit-testable?

You should do it where it makes sense. Not everything is suited to unit testing. For example UI code is very hard to unit test and you often get little benefit from doing so. Business Layer code however is often very suitable for tests and that is where most unit testing is focused.

Unit testing is a massive topic and to fully get an understanding of how it can best benefit you I'd recommend getting hold of a book on unit testing such as "Test Driven Development by Example" which will give you a good grasp on the concepts and how you can apply them to your code.

That solution from the official wiki:

vzctl set $CTID --netfilter full --save

https://openvz.org/VPN_via_the_TUN/TAP_device#Troubleshooting

You can try:

<activity android:name=".YourActivityName"
          android:theme="@style/Theme.Design.NoActionBar">

that works for me

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

My Settings Screenshot:

Thanks to this post.

Just turn off instant run in your settings. You can easily search the keyword "instant" like I showed and it would switch to the window you want.

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

You will get it by tag type="date"...then it will render beautiful calendar and all...

@Html.TextBoxFor(model => model.EndTime, new { type = "date" })

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

I had the same issue and none of the above answers solved the problem, so I tried something very straight-forward: I just putted in my strings.xml \n\t

The complete String looks like this <string name="premium_features_listing_3">- Automatische Aktualisierung der\n\tDatenbank</string>

Results in:

• Automatische Aktualisierung der

  Datenbank

(with no extra line in between)

Maybe it will help others. Regards

If you're at the top level - or able to cleanly get to the top level - of the thread, then just returning is nice. Throwing an exception isn't as clean, as you need to be able to check that nothing's going to catch the exception and ignore it.

The reason you need to use Thread.currentThread() in order to call interrupt() is that interrupt() is an instance method - you need to call it on the thread you want to interrupt, which in your case happens to be the current thread. Note that the interruption will only be noticed the next time the thread would block (e.g. for IO or for a monitor) anyway - it doesn't mean the exception is thrown immediately.

As posted already

All you need to do is to give ownership of the folders to Apache :

but I added -R for chown command: sudo chown -R www-data:www-data /path/to/your/project/vendor sudo chown -R www-data:www-data /path/to/your/project/storage

Quoted from PEP 343 -- The "with" Statement (added import statement):

Redirect stdout temporarily:

import sys
from contextlib import contextmanager
@contextmanager
def stdout_redirected(new_stdout):
    save_stdout = sys.stdout
    sys.stdout = new_stdout
    try:
        yield None
    finally:
        sys.stdout = save_stdout

Used as follows:

with open(filename, "w") as f:
    with stdout_redirected(f):
        print "Hello world"

This isn't thread-safe, of course, but neither is doing this same dance manually. In single-threaded programs (for example in scripts) it is a popular way of doing things.

The JWT is stored on browser, so remove the token deleting the cookie at client side

If you need also to invalidate the token from server side before its expiration time, for example account deleted/blocked/suspended, password changed, permissions changed, user logged out by admin, take a look at Invalidating JSON Web Tokens for some commons techniques like creating a blacklist or rotating tokens

If you're sharing code between C and C++, remember to add the following to the shared.hfile:

#ifdef __cplusplus
extern "C" {
#endif

extern int my_global;
/* other extern declarations ... */

#ifdef __cplusplus
}
#endif

You can use ^ or 0 (Zero) in normal mode to move to the beginning of a line.

^ moves the cursor to the first non-blank character of a line
0 always moves the cursor to the "first column"

You can also use Shifti to move and switch to Insert mode.

Global variables can be used in Node when used wisely.

Declaration of global variables in Node:

a = 10;
GLOBAL.a = 10;
global.a = 10;

All of the above commands the same actions with different syntaxes.

Use global variables when they are not about to be changed

Here an example of something that can happen when using global variables:

// app.js
a = 10; // no var or let or const means global

// users.js
app.get("/users", (req, res, next) => {
   res.send(a); // 10;
});

// permissions.js
app.get("/permissions", (req, res, next) => {
   a = 11; // notice that there is no previous declaration of a in the permissions.js, means we looking for the global instance of a.
   res.send(a); // 11;
});

Explained:

Run users route first and receive 10;

Then run permissions route and receive 11;

Then run again the users route and receive 11 as well instead of 10;

Global variables can be overtaken!

Now think about using express and assignin res object as global.. And you end up with async error become corrupt and server is shuts down.

When to use global vars?

As I said - when var is not about to be changed. Anyways it's more recommended that you will be using the process.env object from the config file.

Here is the alternative solution to check whether a particular string contains some predefined string. It uses IndexOf Function:

'this is your string
Dim strMyString As String = "aaSomethingbb"

'if your string contains these strings
Dim TargetString1 As String = "Something"
Dim TargetString2 As String = "Something2"

If strMyString.IndexOf(TargetString1) <> -1 Or strMyString.IndexOf(TargetString2) <> -1 Then

End If

NOTE: This solution has been tested with Visual Studio 2010.

If the function is printing to System.out, you can capture that output by using the System.setOut method to change System.out to go to a PrintStream provided by you. If you create a PrintStream connected to a ByteArrayOutputStream, then you can capture the output as a String.

// Create a stream to hold the output
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintStream ps = new PrintStream(baos);
// IMPORTANT: Save the old System.out!
PrintStream old = System.out;
// Tell Java to use your special stream
System.setOut(ps);
// Print some output: goes to your special stream
System.out.println("Foofoofoo!");
// Put things back
System.out.flush();
System.setOut(old);
// Show what happened
System.out.println("Here: " + baos.toString());

An "if" is not a loop. Just use the break inside the "if" and it will break out of the "while".

If you ever need to use genuine nested loops, Java has the concept of a labeled break. You can put a label before a loop, and then use the name of the label is the argument to break. It will break outside of the labeled loop.

Any server side stuff such as php declaration must get evaluated in the host file (file with a .php extension) inside the script tags such as below

<script type="text/javascript">
    var1 = "<?php echo 'Hello';?>";
</script>

Then in the .js file, you can use the variable

alert(var1);

If you try to evaluate php declaration in the .js file, it will NOT work

You don't need to give local path. just give cdn link of bootstrap datetimepicker. and it works.

If all you want to do is authenticate against AD using Kerberos, then a simple http://spnego.sourceforge.net/HelloKDC.java program should do it.

Take a look at the project's "pre-flight" documentation which talks about the HelloKDC.java program.

I got a similar error message like TCP error code 10061: No connection could be made because the target machine actively refused it in my current project. I find this 10061 error code cannot distinguish the case that the service endpoint is not started and the case that it is blocked by the firewall. Often, the firewall can be switched off, but the problem is still there.

You can test your code in the below two ways.

1. Insert code to get time A that service is started and time B that client sends the request to the server. If B is earlier than A, it can cause this problem.
2. Change your server port to another port that is also available in the system. You will find the same error code reported.

Above is my fix. It works on my machine. I hope it helps!

maybe this can help:

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

cheers

Yes. add a linked server entry, and use select into using the four part db object naming convention.

Example:

SELECT * INTO targetTable 
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]

Well... its quite simple to get a SQL min date

DateTime sqlMinDateAsNetDateTime = System.Data.SqlTypes.SqlDateTime.MinValue.Value;

With user defined functions, you have to declare every parameter, even if they have a default value.

The following would execute successfully:

IF dbo.CheckIfSFExists( 23, default ) = 0
    SET @retValue = 'bla bla bla;

tl;dr

Use neither.

• java.time.Instant replaces java.util.Date
• java.time.LocalDate replaces java.sql.Date

Neither

java.util.Date vs java.sql.Date: when to use which and why?

Both of these classes are terrible, flawed in design and in implementation. Avoid like the Plague Coronavirus.

Instead use java.time classes, defined in in JSR 310. These classes are an industry-leading framework for working with date-time handling. These supplant entirely the bloody awful legacy classes such as Date, Calendar, SimpleDateFormat, and such.

java.util.Date

The first, java.util.Date is meant to represent a moment in UTC, meaning an offset from UTC of zero hours-minutes-seconds.

java.time.Instant

Now replaced by java.time.Instant.

Instant instant = Instant.now() ;  // Capture the current moment as seen in UTC.

java.time.OffsetDateTime

Instant is the basic building-block class of java.time. For more flexibility, use OffsetDateTime set to ZoneOffset.UTC for the same purpose: representing a moment in UTC.

OffsetDateTime odt = OffsetDateTime.now( ZoneOffset.UTC ) ;

You can send this object to a database by using PreparedStatement::setObject with JDBC 4.2 or later.

myPreparedStatement.setObject( … , odt ) ;

Retrieve.

OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;

java.sql.Date

The java.sql.Date class is also terrible and obsolete.

This class is meant to represent a date only, without a time-of-day and without a time zone. Unfortunately, in a terrible hack of a design, this class inherits from java.util.Date which represents a moment (a date with time-of-day in UTC). So this class is merely pretending to be date-only, while actually carrying a time-of-day and implicit offset of UTC. This causes so much confusion. Never use this class.

java.time.LocalDate

Instead, use java.time.LocalDate to track just a date (year, month, day-of-month) without any time-of-day nor any time zone or offset.

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;
LocalDate ld = LocalDate.now( z ) ;    // Capture the current date as seen in the wall-clock time used by the people of a particular region (a time zone).

Send to the database.

myPreparedStatement.setObject( … , ld ) ;

Retrieve.

LocalDate ld = myResultSet.getObject( … , LocalDate.class ) ;

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.

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

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

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, Java SE 10, Java SE 11, and later - 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
  • Most 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….

Please find in the below code what I developed to support internationalization. It formats the given numeric value to language specific format. In the given example I have used ‘en’ while have tested for ‘es’, ‘fr’ and other countries where in the format varies. It not only stops user from keying characters but formats the value on tab out. Have created components for Number as well as for Decimal format. Apart from this have created parseNumber(value, locale) and parseDecimal(value, locale) functions which will parse the formatted data for any other business purposes. The said function will accept the formatted data and will return the non-formatted value. I have used JQuery validator plugin in the below shared code.

Had the same error with PHP 7 on XAMPP and OSX.

The above mentioned answer in https://stackoverflow.com/ is good, but it did not completely solve the problem for me. I had to provide the complete certificate chain to make file_get_contents() work again. That's how I did it:

Get root / intermediate certificate

First of all I had to figure out what's the root and the intermediate certificate.

The most convenient way is maybe an online cert-tool like the ssl-shopper

There I found three certificates, one server-certificate and two chain-certificates (one is the root, the other one apparantly the intermediate).

All I need to do is just search the internet for both of them. In my case, this is the root:

thawte DV SSL SHA256 CA

And it leads to his url thawte.com. So I just put this cert into a textfile and did the same for the intermediate. Done.

Get the host certificate

Next thing I had to to is to download my server cert. On Linux or OS X it can be done with openssl:

openssl s_client -showcerts -connect whatsyoururl.de:443 </dev/null 2>/dev/null|openssl x509 -outform PEM > /tmp/whatsyoururl.de.cert

Now bring them all together

Now just merge all of them into one file. (Maybe it's good to just put them into one folder, I just merged them into one file). You can do it like this:

cat /tmp/thawteRoot.crt > /tmp/chain.crt
cat /tmp/thawteIntermediate.crt >> /tmp/chain.crt
cat /tmp/tmp/whatsyoururl.de.cert >> /tmp/chain.crt

tell PHP where to find the chain

There is this handy function openssl_get_cert_locations() that'll tell you, where PHP is looking for cert files. And there is this parameter, that will tell file_get_contents() where to look for cert files. Maybe both ways will work. I preferred the parameter way. (Compared to the solution mentioned above).

So this is now my PHP-Code

$arrContextOptions=array(
    "ssl"=>array(
        "cafile" => "/Applications/XAMPP/xamppfiles/share/openssl/certs/chain.pem",
        "verify_peer"=> true,
        "verify_peer_name"=> true,
    ),
);

$response = file_get_contents($myHttpsURL, 0, stream_context_create($arrContextOptions));

That's all. file_get_contents() is working again. Without CURL and hopefully without security flaws.

How about you store it like this? Maybe in username:password format, so

sebastion:password123
anotheruser:password321

Then you can use list($username,$password) = explode(':',file_get_contents('users.txt')); to parse the data on your end.

Here's a macro that I put together:

http://github.com/cjhanson/Objective-C-Optimized-Singleton

It is based on the work here by Matt Gallagher But changing the implementation to use method swizzling as described here by Dave MacLachlan of Google.

I welcome comments / contributions.

Expansion of the same answer

1. This SO post outlines in detail the overheads and storage mechanisms.
2. As noted from point (1), A VARCHAR should always be used instead of TINYTEXT. However, when using VARCHAR, the max rowsize should not exceeed 65535 bytes.
3. As outlined here http://dev.mysql.com/doc/refman/5.0/en/charset-unicode-utf8.html, max 3 bytes for utf-8.

THIS IS A ROUGH ESTIMATION TABLE FOR QUICK DECISIONS!

1. So the worst case assumptions (3 bytes per utf-8 char) to best case (1 byte per utf-8 char)
2. Assuming the english language has an average of 4.5 letters per word
3. x is the number of bytes allocated

x-x

      Type | A= worst case (x/3) | B = best case (x) | words estimate (A/4.5) - (B/4.5)
-----------+---------------------------------------------------------------------------
  TINYTEXT |              85     | 255               | 18 - 56
      TEXT |          21,845     | 65,535            | 4,854.44 - 14,563.33  
MEDIUMTEXT |       5,592,415     | 16,777,215        | 1,242,758.8 - 3,728,270

Please refer to Chris V's answer as well : https://stackoverflow.com/a/35785869/1881812

One thing which works for me every time is:

go to --> build.gradle (Module: app) file of your project --> do a little change (for example: put a space somewhere and remove it back) --> then android studio will ask you to sync your gradle file--> at top right corner of the file --> select "sync now".

After syncing completes, it'll resolve the issue in most of the cases.

Below code will list directories and the files within the dir. The other one is os.walk

def print_directory_contents(sPath):
        import os                                       
        for sChild in os.listdir(sPath):                
            sChildPath = os.path.join(sPath,sChild)
            if os.path.isdir(sChildPath):
                print_directory_contents(sChildPath)
            else:
                print(sChildPath)

you might have bash but it is still a windows window manager. Highlite some text in the bash terminal window. Right click on the title bar, select "Edit", select "Copy", Now Right Click again on the Title bar, select "Edit" , Select "Paste", Done. You should be able to Highlite text, hit "Enter" then Control V but this seems to be broken

With usort. Here's a generic solution, that you can use for different columns:

class TableSorter {
  protected $column;
  function __construct($column) {
    $this->column = $column;
  }
  function sort($table) {
    usort($table, array($this, 'compare'));
    return $table;
  }
  function compare($a, $b) {
    if ($a[$this->column] == $b[$this->column]) {
      return 0;
    }
    return ($a[$this->column] < $b[$this->column]) ? -1 : 1;
  }
}

To sort by first column:

$sorter = new TableSorter(0); // sort by first column
$mdarray = $sorter->sort($mdarray);

I think (based on your comments) that I understand what you want to do: you want your local copy of the repository to have neither the ordinary local branch master, nor the remote-tracking branch origin/master, even though the repository you cloned—the github one—has a local branch master that you do not want deleted from the github version.

You can do this by deleting the remote-tracking branch locally, but it will simply come back every time you ask your git to synchronize your local repository with the remote repository, because your git asks their git "what branches do you have" and it says "I have master" so your git (re)creates origin/master for you, so that your repository has what theirs has.

To delete your remote-tracking branch locally using the command line interface:

git branch -d -r origin/master

but again, it will just come back on re-synchronizations. It is possible to defeat this as well (using remote.origin.fetch manipulation), but you're probably better off just being disciplined enough to not create or modify master locally.

You can just use return to end the method's execution

select Id, Count, @total := @total + Count as cumulative_sum
from YourTable, (Select @total := 0) as total ;

Pig is useful for ETL kind of workloads generally speaking. For example set of transformations you need to do to your data every day.

Hive shines when you need to run adhoc queries or just want to explore data. It sometimes can act as interface to your visualisation Layer ( Tableau/Qlikview).

Both are essential and serve different purpose.

In xamarin ios suppose your label name is title then do the following

title.TextAlignment = UITextAlignment.Center;

This answer is an extension to @raphadko's answer.

If you need to extract manually the captcha code (like in ajax requests) you have to call:

grecaptcha.getResponse(widget_id)

But how can you retrieve the widget id parameter?

I use this definition of CaptchaCallback to store the widget id of each g-recaptcha box (as an HTML data attribute):

var CaptchaCallback = function() {
    jQuery('.g-recaptcha').each(function(index, el) {
        var widgetId = grecaptcha.render(el, {'sitekey' : 'your code'});
        jQuery(this).attr('data-widget-id', widgetId);
    });
};

Then I can call:

grecaptcha.getResponse(jQuery('#your_recaptcha_box_id').attr('data-widget-id'));

to extract the code.

ws2s project is aimed at bring socket to browser-side js. It is a websocket server which transform websocket to socket.

ws2s schematic diagram

code sample:

var socket = new WS2S("wss://ws2s.feling.io/").newSocket()

socket.onReady = () => {
  socket.connect("feling.io", 80)
  socket.send("GET / HTTP/1.1\r\nHost: feling.io\r\nConnection: close\r\n\r\n")
}

socket.onRecv = (data) => {
  console.log('onRecv', data)

Here is an interesting case I thought I should share.

Let's say that you have an array of objects and an array of selected filters.

let arr = [
  { id: 'x', tags: ['foo'] },
  { id: 'y', tags: ['foo', 'bar'] },
  { id: 'z', tags: ['baz'] }
];

const filters = ['foo'];

To apply the selected filters to this structure we can

if (filters.length > 0)
  arr = arr.filter(obj =>
    obj.tags.some(tag => filters.includes(tag))
  );

// [
//   { id: 'x', tags: ['foo'] },
//   { id: 'y', tags: ['foo', 'bar'] }
// ]

I had trouble deleting a cookie made via JavaScript and after I added the host it worked (scroll the code below to the right to see the location.host). After clearing the cookies on a domain try the following to see the results:

if (document.cookie.length==0)
{
 document.cookie = 'name=example; expires='+new Date((new Date()).valueOf()+1000*60*60*24*15)+'; path=/; domain='+location.host;

 if (document.cookie.length==0) {alert('Cookies disabled');}
 else
 {
  document.cookie = 'name=example; expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/; domain='+location.host;

  if (document.cookie.length==0) {alert('Created AND deleted cookie successfully.');}
  else {alert('document.cookies.length = '+document.cookies.length);}
 }
}

I suggest you to use provider. Provide is good when you want to configure it first before to use (against Service/Factory)

Something like:

.provider('Magazines', function() {

    this.url = '/';
    this.urlArray = '/';
    this.organId = 'Default';

    this.$get = function() {
        var url = this.url;
        var urlArray = this.urlArray;
        var organId = this.organId;

        return {
            invoke: function() {
                return ......
            }
        }
    };

    this.setUrl  = function(url) {
        this.url = url;
    };

   this.setUrlArray  = function(urlArray) {
        this.urlArray = urlArray;
    };

    this.setOrganId  = function(organId) {
        this.organId = organId;
    };
});

.config(function(MagazinesProvider){
    MagazinesProvider.setUrl('...');
    MagazinesProvider.setUrlArray('...');
    MagazinesProvider.setOrganId('...');
});

And now controller:

function MyCtrl($scope, Magazines) {        

        Magazines.invoke();

       ....

}

If you create a new repository from the Github web GUI, you sometimes get the name 'main' instead of 'master'. By using the command git status from your terminal you'd see which location you are. In some cases, you'd see origin/main.

If you are trying to push your app to a cloud service via CLI then use 'main', not 'master'.

example: git push heroku main

In addition to setting the registry entry for AuthServerWhitelist you should also set AuthSchemes: "ntlm,negotiate" (or just "ntlm" as appropriate for your situation). Using the above templates the policy for that will be "Supported authentication schemes"

Basically, this way you combine things because jQuery is a framework which mostly focuses on HTML elements, you basically preventing the default, but at the same time, you stop propagation to bubble up.

So we can simply say, return false in jQuery is equal to:

return false is e.preventDefault AND e.stopPropagation

But also don't forget it's all in jQuery or DOM related functions, when you run it on the element, basically, it prevents everything from firing including the default behaviour and propagation of the event.

Basically before starting using return false;, first understand what e.preventDefault(); and e.stopPropagation(); do, then if you think you need both at the same time, then simply use it.

So basically this code below:

$('div').click(function () {
  return false;
});

is equal to this code:

$('div').click(function (event) {
  event.preventDefault();
  event.stopPropagation();
});

If you really need multiple columns in your result, and the amount of options is limited, you can even do this:

select
  ordered_item.id as `Id`,
  ordered_item.Item_Name as `ItemName`,
  if(ordered_options.id=1,Ordered_Options.Value,null) as `Option1`,
  if(ordered_options.id=2,Ordered_Options.Value,null) as `Option2`,
  if(ordered_options.id=43,Ordered_Options.Value,null) as `Option43`,
  if(ordered_options.id=44,Ordered_Options.Value,null) as `Option44`,
  GROUP_CONCAT(if(ordered_options.id not in (1,2,43,44),Ordered_Options.Value,null)) as `OtherOptions`
from
  ordered_item,
  ordered_options
where
  ordered_item.id=ordered_options.ordered_item_id
group by
  ordered_item.id

Here's a fairly complete solution for recursively encoding and decoding datetime.datetime and datetime.date objects using the standard library json module. This needs Python >= 2.6 since the %f format code in the datetime.datetime.strptime() format string is only supported in since then. For Python 2.5 support, drop the %f and strip the microseconds from the ISO date string before trying to convert it, but you'll loose microseconds precision, of course. For interoperability with ISO date strings from other sources, which may include a time zone name or UTC offset, you may also need to strip some parts of the date string before the conversion. For a complete parser for ISO date strings (and many other date formats) see the third-party dateutil module.

Decoding only works when the ISO date strings are values in a JavaScript literal object notation or in nested structures within an object. ISO date strings, which are items of a top-level array will not be decoded.

I.e. this works:

date = datetime.datetime.now()
>>> json = dumps(dict(foo='bar', innerdict=dict(date=date)))
>>> json
'{"innerdict": {"date": "2010-07-15T13:16:38.365579"}, "foo": "bar"}'
>>> loads(json)
{u'innerdict': {u'date': datetime.datetime(2010, 7, 15, 13, 16, 38, 365579)},
u'foo': u'bar'}

And this too:

>>> json = dumps(['foo', 'bar', dict(date=date)])
>>> json
'["foo", "bar", {"date": "2010-07-15T13:16:38.365579"}]'
>>> loads(json)
[u'foo', u'bar', {u'date': datetime.datetime(2010, 7, 15, 13, 16, 38, 365579)}]

But this doesn't work as expected:

>>> json = dumps(['foo', 'bar', date])
>>> json
'["foo", "bar", "2010-07-15T13:16:38.365579"]'
>>> loads(json)
[u'foo', u'bar', u'2010-07-15T13:16:38.365579']

The package broom comes in handy here (it uses the "tidy" format).

tidy(mg) will give a nicely formated data.frame with coefficients, t statistics etc. Works also for other models (e.g. plm, ...).

Example from broom's github repo:

lmfit <- lm(mpg ~ wt, mtcars)
require(broom)    
tidy(lmfit)

      term estimate std.error statistic   p.value
1 (Intercept)   37.285   1.8776    19.858 8.242e-19
2          wt   -5.344   0.5591    -9.559 1.294e-10

is.data.frame(tidy(lmfit))
[1] TRUE

@Grantismo provides a great explanation on the overall. If you wish to know who people are actually doing this things i suggest you to take a look at how google did for the Google IO App of 2014 (it's always worth taking a deep look at the source code of these apps that they release. There's a lot to learn from there).

Here's a blog post about it: http://android-developers.blogspot.com.br/2014/09/conference-data-sync-gcm-google-io.html

Essentially, on the application side: GCM for signalling, Sync Adapter for data fetching and talking properly with Content Provider that will make things persistent (yeah, it isolates the DB from direct access from other parts of the app).

Also, if you wish to take a look at the 2015's code: https://github.com/google/iosched

(Get-Host).UI.RawUI.WindowTitle = "Stay Awake"

[System.Console]::BufferWidth  = [System.Console]::WindowWidth  = 40
[System.Console]::BufferHeight = [System.Console]::WindowHeight = 10

$shell = New-Object -ComObject WScript.Shell

$start_time = Get-Date -UFormat %s <# Get the date in MS #>
$current_time = $start_time
$elapsed_time = 0

Write-Host "I am awake!"

Start-Sleep -Seconds 5

$count = 0

while($true) {

  $shell.sendkeys("{NUMLOCK}{NUMLOCK}") <# Fake some input! #>

  if ($count -eq 8) {

    $count = 0
    Clear-Host

  }

  if ($count -eq 0) {

    $current_time = Get-Date -UFormat %s
    $elapsed_time = $current_time - $start_time

    Write-Host "I've been awake for "([System.Math]::Round(($elapsed_time / 60), 2))" minutes!"

  } else { Write-Host "Must stay awake..." }

  $count ++

  Start-Sleep -Seconds 2.5

}

The part that matters is $shell.sendkeys("{NUMLOCK}{NUMLOCK}") This registers two presses on the numlock key and fools the shell into thinking input was entered. I wrote this today after searching through various scripts that didn't work for me. Hope it helps someone!

I use:

let jsonFile = {};    
let schemaJson = {};    
schemaJson["properties"] = {};    
schemaJson["properties"]["key"] = "value";
jsonFile.concat(schemaJson);

If, after adding lines:

<property
name="hibernate.connection.zeroDateTimeBehavior">convertToNull</property>

hibernate.connection.zeroDateTimeBehavior=convertToNull

<connection-property
name="zeroDateTimeBehavior">convertToNull</connection-property>

continues to be an error:

Illegal DATETIME, DATE, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00 00:00:00' or '0000-00-00').

find lines:

1) resultSet.getTime("time"); // time = 00:00:00
2) resultSet.getTimestamp("timestamp"); // timestamp = 00000000000000
3) resultSet.getDate("date"); // date = 0000-00-00 00:00:00

replace with the following lines, respectively:

1) Time.valueOf(resultSet.getString("time"));
2) Timestamp.valueOf(resultSet.getString("timestamp"));
3) Date.valueOf(resultSet.getString("date"));

I was able to do that with the following 2 lines, I had an array called selected_items used to get all selected items on a dataTable

selected_items = null;
selected_items = [];

Use H or HH instead of hh. See http://momentjs.com/docs/#/parsing/string-format/

As ivan.sim writes in his answer

1. Ensure that your user account has administrator privilege.
2. Disable UAC(User Account Control) as it restricts certain administrative function needed to run a web server.
3. Install in C://xampp.

Problem with the correct answer is in the explanation of point 2., and magicandre1981 writes more about it

Moving the slider down doesn't completely disable UAC since Windows 8. This is changed compared to Windows 7, because the new Store apps require an active UAC. With UAC off, they no longer run.

How can we then disable UAC and install XAMPP?

Easy. Go to Registry Editor and navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Right click EnableLUA and modify the Value data to 0.

Then restart your computer and you're ready to install XAMPP.

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

Did you specify your own tabIndex values for each element you want to cycle through? if so, you can try this:

var lasTabIndex = 10; //Set this to the highest tabIndex you have
function OnFocusOut()
{
    var currentElement = $get(currentElementId); // ID set by OnFocusIn 

    var curIndex = $(currentElement).attr('tabindex'); //get the tab index of the current element
    if(curIndex == lastTabIndex) { //if we are on the last tabindex, go back to the beginning
        curIndex = 0;
    }
    $('[tabindex=' + (curIndex + 1) + ']').focus(); //set focus on the element that has a tab index one greater than the current tab index
}

You are using jquery, right?

It is the version key.It gets updated whenever a new update is made. I personally don't like to disable it .

Read this solution if you want to know more [1]: Mongoose versioning: when is it safe to disable it?

Seems a bit too late, but there is a PPA repository with SmartGit, enjoy! =)

You can run this command from the DB2 command line processor (CLP) or from inside a SQL application by calling the ADMIN_CMD stored procedure

EXPORT TO result.csv OF DEL MODIFIED BY NOCHARDEL 
SELECT col1, col2, coln FROM testtable;

There are lots of options for IMPORT and EXPORT that you can use to create a data file that meets your needs. The NOCHARDEL qualifier will suppress double quote characters that would otherwise appear around each character column.

Keep in mind that any SELECT statement can be used as the source for your export, including joins or even recursive SQL. The export utility will also honor the sort order if you specify an ORDER BY in your SELECT statement.

You mentioned Visual Studio. This is for Visual Studio 2013. In the "Menu and Tools" in the second line , right below Debug you have a dropdown box giving you the list / option of "Emulators" .Your IE should be in the option , select that and you are good to go. Easy way .

The python version could be:

re.compile(r'\A(?:[\da-f]{2}[:-]){5}[\da-f]{2}\Z',re.I)

Swift-Extension:

extension UIImage{
     func toBase64() -> String{
          var imageData = UIImagePNGRepresentation(self)
          return imageData.base64EncodedStringWithOptions(.allZeros)
     }
}

This is a recursive version that works with letter drives as well as UNC. I used the error catching to implement it but if anyone can do one without, I would be interested to see it. This approach works from the branches to the root so it will be somewhat usable when you don't have permissions in the root and lower parts of the directory tree.

' Reverse create directory path. This will create the directory tree from the top    down to the root.
' Useful when working on network drives where you may not have access to the directories close to the root
Sub RevCreateDir(strCheckPath As String)
    On Error GoTo goUpOneDir:
    If Len(Dir(strCheckPath, vbDirectory)) = 0 And Len(strCheckPath) > 2 Then
        MkDir strCheckPath
    End If
    Exit Sub
' Only go up the tree if error code Path not found (76).
goUpOneDir:
    If Err.Number = 76 Then
        Call RevCreateDir(Left(strCheckPath, InStrRev(strCheckPath, "\") - 1))
        Call RevCreateDir(strCheckPath)
    End If
End Sub

The file name u used spring-dispatcher-servlet.xml
kindly check in web.xml
servlet name as spring-dispatcher at both tag  <servlet> and <servlet-mapping>
in your case it should be

</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern></url-pattern>

According to documentation:

random.sample(population, k)

Return a k length list of unique elements chosen from the population sequence. Used for random sampling without replacement.

Basically, it picks k unique random elements, a sample, from a sequence:

>>> import random
>>> c = list(range(0, 15))
>>> c
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
>>> random.sample(c, 5)
[9, 2, 3, 14, 11]

random.sample works also directly from a range:

>>> c = range(0, 15)
>>> c
range(0, 15)
>>> random.sample(c, 5)
[12, 3, 6, 14, 10]

In addition to sequences, random.sample works with sets too:

>>> c = {1, 2, 4}
>>> random.sample(c, 2)
[4, 1]

However, random.sample doesn't work with arbitrary iterators:

>>> c = [1, 3]
>>> random.sample(iter(c), 5)
TypeError: Population must be a sequence or set.  For dicts, use list(d).

Just use substring: "apple".substring(3); will return le

As shailbenq suggested, phoneformat is awesome.

Include phone format in your website. Create a filter for the angular module or your application.

angular.module('ng')
.filter('tel', function () {
    return function (phoneNumber) {
        if (!phoneNumber)
            return phoneNumber;

        return formatLocal('US', phoneNumber); 
    }
});

Then you can use the filter in your HTML.

{{phone|tel}} 
OR
<span ng-bind="phone|tel"></span>

If you want to use the filter in your controller.

var number = '5553219876';
var newNumber = $filter('tel')(number);

Runtime.getCurrentRumtime().halt(0);

I was looking for a solution to remove strings' masks, specifically from Brazilian phones numbers, this post not answered but inspired me. This is my solution:

>>> phone_number = '+55(11)8715-9877'
>>> ''.join([n for n in phone_number if n.isdigit()])
'551187159877'

You can simply use this methods.

console.log(new Date().toLocaleTimeString([], { hour: '2-digit', minute: "2-digit", hour12: false }));
console.log(new Date().toLocaleTimeString([], { hour: '2-digit', minute: "2-digit" }));

For responsive images. You can add the picture and source tags within the figure tag.

<figure>
  <picture>
    <source media="(min-width: 750px)" srcset="images/image_2x.jpg"/>
    <source media="(min-width: 500px)" srcset="images/image.jpg" />
    <img src="images.jpg" alt="An image">
  </picture>
  <figcaption>Caption goes here</figcaption>
</figure>

You can use a kind of continue by using a nested Do ... Loop While False:

'This sample will output 1 and 3 only

Dim i As Integer

For i = 1 To 3: Do

    If i = 2 Then Exit Do 'Exit Do is the Continue

    Debug.Print i

Loop While False: Next i

With n being the line number:

• ng: Jump to line number n. Default is the start of the file.
• nG: Jump to line number n. Default is the end of the file.

So to go to line number 320123, you would type 320123g.

Copy-pasted straight from Wikipedia.

I was basically looking for the same thing. Specifically, I wanted the following:

1. To use express.js, which wraps Connect's middleware capability
2. "Form based" authentication
3. Granular control over which routes are authenticated
4. A database back-end for users/passwords
5. Use sessions

What I ended up doing was creating my own middleware function check_auth that I pass as an argument to each route I want authenticated. check_auth merely checks the session and if the user is not logged in, then redirects them to the login page, like so:

function check_auth(req, res, next) {

  //  if the user isn't logged in, redirect them to a login page
  if(!req.session.login) {
    res.redirect("/login");
    return; // the buck stops here... we do not call next(), because
            // we don't want to proceed; instead we want to show a login page
  }

  //  the user is logged in, so call next()
  next();
}

Then for each route, I ensure this function is passed as middleware. For example:

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

Finally, we need to actually handle the login process. This is straightforward:

app.get('/login', function(req, res) {
  res.render("login", {layout:false});
});

app.post('/login', function(req, res) {

  // here, I'm using mongoose.js to search for the user in mongodb
  var user_query = UserModel.findOne({email:req.body.email}, function(err, user){
    if(err) {
      res.render("login", {layout:false, locals:{ error:err } });
      return;
    }

    if(!user || user.password != req.body.password) {
      res.render("login",
        {layout:false,
          locals:{ error:"Invalid login!", email:req.body.email }
        }
      );
    } else {
      // successful login; store the session info
      req.session.login = req.body.email;
      res.redirect("/");
    }
  });
});

At any rate, this approach was mostly designed to be flexible and simple. I'm sure there are numerous ways to improve it. If you have any, I'd very much like your feedback.

EDIT: This is a simplified example. In a production system, you'd never want to store & compare passwords in plain text. As a commenter points out, there are libs that can help manage password security.

Depends on the exact question!

Normally pause does the job within a .bat file.

If you want cmd.exe not to close to be able to remain typing, use cmd /k command at the end of the file.

for (int i = 0; i < list.size(); i++) {
        if (i < list.size() - 1) {
            if (list.get(i) > list.get(i + 1)) {
                int j = list.get(i);
                list.remove(i);
                list.add(i, list.get(i));
                list.remove(i + 1);
                list.add(j);
                i = -1;
            }
        }
    }

This is the notorious floating point rounding issue. Just add a very small number, to correct the issue.

double a;
a=3669.0;
int b;
b=a+ 1e-9;

Add the CSS and JS in The Layout Folder.Access anywhere in the project

  <!--// Stylesheets //-->
    <?php
        $themepath=Yii::app()->theme->baseUrl;
        Yii::app()->clientScript->registerCoreScript("jquery");
    ?>

        <link href="<?php echo $themepath."/css/custom.css"; ?>" rel="stylesheet" media="all" />


<!--// Javascript //-->
<?php Yii::app()->clientScript->registerCoreScript("jquery"); ?>
</script> -->
<script type="text/javascript" src="<?php echo $themepath; ?>/js/video.min.js"></script>

In my case spotify.exe was using the same port which my web api project wanted to use on a development machine. The port number was 4381.

I quit Spotify and everything worked well again :)

• import sys out of hello function.
• arguments should be converted to int.
• String literal that contain ' should be escaped or should be surrouned by ".
• Did you invoke the program with python hello.py <some-number> <some-number> in command line?

import sys

def hello(a,b):
    print "hello and that's your sum:", a + b

if __name__ == "__main__":
    a = int(sys.argv[1])
    b = int(sys.argv[2])
    hello(a, b)

You can do this with make - with gnu make it is the -j flag (this will also help on a uniprocessor machine).

For example if you want 4 parallel jobs from make:

make -j 4

You can also run gcc in a pipe with

gcc -pipe

This will pipeline the compile stages, which will also help keep the cores busy.

If you have additional machines available too, you might check out distcc, which will farm compiles out to those as well.

UIButton will not support setTextAlignment. So You need to go with setContentHorizontalAlignment for button text alignment

For your reference

[buttonName setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];

you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.

def perm(string):
   res=[]
   for j in range(0,len(string)):
       if(len(string)>1):
           for i in perm(string[1:]):
               res.append(string[0]+i)
       else:
           return [string];
       string=string[1:]+string[0];
   return res;
l=set(perm("abcde"))

This is one way to generate permutations with recursion, you can understand the code easily by taking strings 'a','ab' & 'abc' as input.

You get all N! permutations with this, without duplicates.

Another way to check if FB has initialized is by using the following code:

ns.FBInitialized = function () {
    return typeof (FB) != 'undefined' && window.fbAsyncInit.hasRun;
};

Thus in your page ready event you could check ns.FBInitialized and defer the event to later phase by using setTimeOut.

 BigDecimal pi = new BigDecimal(3.14);
 BigDecimal pi4 = new BigDecimal(12.56);

 System.out.printf("%.2f",pi);

// prints 3.14

System.out.printf("%.0f",pi4);

// prints 13

Ok, I know that this question is actually solved but I decided to share my solution for this. I've created abstract parent class for my Fragment:

public abstract class ABaseFragment extends Fragment{

    protected IActivityEnabledListener aeListener;

    protected interface IActivityEnabledListener{
        void onActivityEnabled(FragmentActivity activity);
    }

    protected void getAvailableActivity(IActivityEnabledListener listener){
        if (getActivity() == null){
            aeListener = listener;

        } else {
            listener.onActivityEnabled(getActivity());
        }
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) activity);
            aeListener = null;
        }
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        if (aeListener != null){
            aeListener.onActivityEnabled((FragmentActivity) context);
            aeListener = null;
        }
    }
}

As you can see, I've added a listener so, whenever I'll need to get Fragments Activity instead of standard getActivity(), I'll need to call

 getAvailableActivity(new IActivityEnabledListener() {
        @Override
        public void onActivityEnabled(FragmentActivity activity) {
            // Do manipulations with your activity
        }
    });

Use this:

$parameter = $_SERVER['QUERY_STRING'];
echo $parameter;

Or just use:

$parameter = $_GET['link'];
echo $parameter ;

You cannot use the Directory directive in .htaccess. However if you create a .htaccess file in the /system directory and place the following in it, you will get the same result

#place this in /system/.htaccess as you had before
deny from all

Do whatever you want to do after the file loads successfully.just after the completion of your file processing set the value of file control to blank string.so the .change() will always be called even the file name changes or not. like for example you can do this thing and worked for me like charm

  $('#myFile').change(function () {
    LoadFile("myFile");//function to do processing of file.
    $('#myFile').val('');// set the value to empty of myfile control.
    });

With pandas it can be done as:

If lakes is your DataFrame:

area_dict = lakes.to_dict('records')

Here's a complete sample that worked for me. The boundary value in the request is added automatically by .NET.

var url = "http://localhost/api/v1/yourendpointhere";
var filePath = @"C:\path\to\image.jpg";

HttpClient httpClient = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();

FileStream fs = File.OpenRead(filePath);
var streamContent = new StreamContent(fs);

var imageContent = new ByteArrayContent(streamContent.ReadAsByteArrayAsync().Result);
imageContent.Headers.ContentType = MediaTypeHeaderValue.Parse("multipart/form-data");

form.Add(imageContent, "image", Path.GetFileName(filePath));
var response = httpClient.PostAsync(url, form).Result;

Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with 'npm users' but that is also more administrative overhead. See here for the options to deal with permissions from the documentation: https://docs.npmjs.com/getting-started/fixing-npm-permissions

I would go for option 2:

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Make a directory for global installations:

 mkdir ~/.npm-global

Configure npm to use the new directory path:

 npm config set prefix '~/.npm-global'

Open or create a ~/.profile file and add this line:

 export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:

 source ~/.profile

Test: Download a package globally without using sudo.

npm install -g jshint

If still show permission error run (mac os):

sudo chown -R $USER ~/.npm-global   

This works with the default ubuntu install of:

sudo apt-get install nodejs npm

I recommend nvm if you want more flexibility in managing versions: https://github.com/creationix/nvm

On MacOS use brew, it should work without sudo out of the box if you're on a recent npm version. Enjoy :)

for example kill pts/0

pkill -9 -t pts/0

It will work.

long yourmilliseconds = System.currentTimeMillis();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy HH:mm");    
Date resultdate = new Date(yourmilliseconds);
System.out.println(sdf.format(resultdate));

for D in `find . -type d`
do
    //Do whatever you need with D
done

call.request().toString();

Screenshot request which is being sent to server:

The worst thing of using just

console.log({'some stuff': 2} + '\n' + 'something')

is that all stuff are converted to the string and if you need object to show you may see next:

[object Object]

Thus my variant is the next code:

console.log({'some stuff': 2},'\n' + 'something');

You can't simulate a click event with javascript. jQuery .trigger() function only fires an event named "click" on the element, which you can capture with .on() jQuery method.

First you store your text file in to raw folder.

private void loadWords() throws IOException {
    Log.d(TAG, "Loading words...");
    final Resources resources = mHelperContext.getResources();
    InputStream inputStream = resources.openRawResource(R.raw.definitions);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

    try {
        String line;
        while ((line = reader.readLine()) != null) {
            String[] strings = TextUtils.split(line, "-");
            if (strings.length < 2)
                continue;
            long id = addWord(strings[0].trim(), strings[1].trim());
            if (id < 0) {
                Log.e(TAG, "unable to add word: " + strings[0].trim());
            }
        }
    } finally {
        reader.close();
    }
    Log.d(TAG, "DONE loading words.");
}

Check your servers error log, typically /var/log/apache2/error.log.

In C# 6 you can use string interpolation:

string name = "John";
string result = $"Hello {name}";

The syntax highlighting for this in Visual Studio makes it highly readable and all of the tokens are checked.

You can use the build in __file__ variable. It contains the path of the current file. I would implement getBaseOfProject in a module in the root of your project. There I would get the path part of __file__ and would return that. This method can then be used everywhere in your project.

The following works without flattening the folder structure:

gulp.src(['input/folder/**/*']).pipe(gulp.dest('output/folder'));

The '**/*' is the important part. That expression is a glob which is a powerful file selection tool. For example, for copying only .js files use: 'input/folder/**/*.js'

This question shows precisely why I like to do things the way I mentioned in my question is const after type id acceptable?

In short, I find the easiest way to remember the rule is that the "const" goes after the thing it applies to. So in your question, "int const *" means that the int is constant, while "int * const" would mean that the pointer is constant.

If someone decides to put it at the very front (eg: "const int *"), as a special exception in that case it applies to the thing after it.

Many people like to use that special exception because they think it looks nicer. I dislike it, because it is an exception, and thus confuses things.

This seemed the simplest solution:

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/$
RewriteRule (.*) http://www.example.com/store [R=301,L]

I was getting redirect loops with some of the other solutions.

node-debug -p 8888 scriptFileName.js

I've literally just arrived at the answer in my case. I'm creating a system that has implemented a create method, so I was getting this actual error because I was accessing the overridden version not the one from Eloquent.

Hope that help?

When you use --user option with pip, the package gets installed in user's folder instead of global folder and you won't need to run pip command with admin privileges.

The location of user's packages folder can be found using:

python -m site --user-site

This will print something like:

C:\Users\%USERNAME%\AppData\Roaming\Python\Python35\site-packages

When you don't use --user option with pip, the package gets installed in global folder given by:

python -c "import site; print(site.getsitepackages())"

This will print something like:

['C:\\Program Files\\Anaconda3', 'C:\\Program Files\\Anaconda3\\lib\\site-packages'

Note: Above printed values are for On Windows 10 with Anaconda 4.x installed with defaults.

Example from the guide:

\newcommand{\example}[2][YYY]{Mandatory arg: #2;
                                 Optional arg: #1.}

This defines \example to be a command with two arguments, 
referred to as #1 and #2 in the {<definition>}--nothing new so far. 
But by adding a second optional argument to this \newcommand 
(the [YYY]) the first argument (#1) of the newly defined 
command \example is made optional with its default value being YYY.

Thus the usage of \example is either:

   \example{BBB}
which prints:
Mandatory arg: BBB; Optional arg: YYY.
or:
   \example[XXX]{AAA}
which prints:
Mandatory arg: AAA; Optional arg: XXX.

Use your jquery like this

$('.home').css({'background-image':'url(images/tabs3.png)'});

Use .rsplit() or .rpartition() instead:

s.rsplit(',', 1)
s.rpartition(',')

str.rsplit() lets you specify how many times to split, while str.rpartition() only splits once but always returns a fixed number of elements (prefix, delimiter & postfix) and is faster for the single split case.

Demo:

>>> s = "a,b,c,d"
>>> s.rsplit(',', 1)
['a,b,c', 'd']
>>> s.rsplit(',', 2)
['a,b', 'c', 'd']
>>> s.rpartition(',')
('a,b,c', ',', 'd')

Both methods start splitting from the right-hand-side of the string; by giving str.rsplit() a maximum as the second argument, you get to split just the right-hand-most occurrences.

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print(); 
});

Something that isn't mentioned here and is useful: adding a suffix to the day. I decoupled the suffix logic so you can use it for any number you like, not just dates.

import time

def num_suffix(n):
    '''
    Returns the suffix for any given int
    '''
    suf = ('th','st', 'nd', 'rd')
    n = abs(n) # wise guy
    tens = int(str(n)[-2:])
    units = n % 10
    if tens > 10 and tens < 20:
        return suf[0] # teens with 'th'
    elif units <= 3:
        return suf[units]
    else:
        return suf[0] # 'th'

def day_suffix(t):
    '''
    Returns the suffix of the given struct_time day
    '''
    return num_suffix(t.tm_mday)

# Examples
print num_suffix(123)
print num_suffix(3431)
print num_suffix(1234)
print ''
print day_suffix(time.strptime("1 Dec 00", "%d %b %y"))
print day_suffix(time.strptime("2 Nov 01", "%d %b %y"))
print day_suffix(time.strptime("3 Oct 02", "%d %b %y"))
print day_suffix(time.strptime("4 Sep 03", "%d %b %y"))
print day_suffix(time.strptime("13 Nov 90", "%d %b %y"))
print day_suffix(time.strptime("14 Oct 10", "%d %b %y"))???????

The problem is that value is ignored when ng-model is present.

Firefox, which doesn't currently support type="date", will convert all the values to string. Since you (rightly) want date to be a real Date object and not a string, I think the best choice is to create another variable, for instance dateString, and then link the two variables:

<input type="date" ng-model="dateString" />

function MainCtrl($scope, dateFilter) {
    $scope.date = new Date();

    $scope.$watch('date', function (date)
    {
        $scope.dateString = dateFilter(date, 'yyyy-MM-dd');
    });

    $scope.$watch('dateString', function (dateString)
    {
        $scope.date = new Date(dateString);
    });
}

Fiddle

The actual structure is for demonstration purposes only. You'd be better off creating your own directive, especially in order to:

• allow formats other than yyyy-MM-dd,
• be able to use NgModelController#$formatters and NgModelController#$parsers rather than the artifical dateString variable (see the documentation on this subject).

Please notice that I've used yyyy-MM-dd, because it's a format directly supported by the JavaScript Date object. In case you want to use another one, you must make the conversion yourself.

EDIT

Here is a way to make a clean directive:

myModule.directive(
    'dateInput',
    function(dateFilter) {
        return {
            require: 'ngModel',
            template: '<input type="date"></input>',
            replace: true,
            link: function(scope, elm, attrs, ngModelCtrl) {
                ngModelCtrl.$formatters.unshift(function (modelValue) {
                    return dateFilter(modelValue, 'yyyy-MM-dd');
                });

                ngModelCtrl.$parsers.unshift(function(viewValue) {
                    return new Date(viewValue);
                });
            },
        };
});

Fiddle

That's a basic directive, there's still a lot of room for improvement, for example:

• allow the use of a custom format instead of yyyy-MM-dd,
• check that the date typed by the user is correct.

I'd suggest using a pseudo element in place of the overlay element. Because pseudo elements can't be added on enclosed img elements, you would still need to wrap the img element though.

LIVE EXAMPLE HERE -- EXAMPLE WITH TEXT

<div class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

As for the CSS, set optional dimensions on the .image element, and relatively position it. If you are aiming for a responsive image, just omit the dimensions and this will still work (example). It's just worth noting that the dimensions must be on the parent element as opposed to the img element itself, see.

.image {
    position: relative;
    width: 400px;
    height: 400px;
}

Give the child img element a width of 100% of the parent and add vertical-align:top to fix the default baseline alignment issues.

.image img {
    width: 100%;
    vertical-align: top;
}

As for the pseudo element, set a content value and absolutely position it relative to the .image element. A width/height of 100% will ensure that this works with varying img dimensions. If you want to transition the element, set an opacity of 0 and add the transition properties/values.

.image:after {
    content: '\A';
    position: absolute;
    width: 100%; height:100%;
    top:0; left:0;
    background:rgba(0,0,0,0.6);
    opacity: 0;
    transition: all 1s;
    -webkit-transition: all 1s;
}

Use an opacity of 1 when hovering over the pseudo element in order to facilitate the transition:

.image:hover:after {
    opacity: 1;
}

END RESULT HERE

If you want to add text on hover:

For the simplest approach, just add the text as the pseudo element's content value:

EXAMPLE HERE

.image:after {
    content: 'Here is some text..';
    color: #fff;

    /* Other styling.. */
}

That should work in most instances; however, if you have more than one img element, you might not want the same text to appear on hover. You could therefore set the text in a data-* attribute and therefore have unique text for every img element.

EXAMPLE HERE

.image:after {
    content: attr(data-content);
    color: #fff;
}

With a content value of attr(data-content), the pseudo element adds the text from the .image element's data-content attribute:

<div data-content="Text added on hover" class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

You can add some styling and do something like this:

EXAMPLE HERE

In the above example, the :after pseudo element serves as the black overlay, while the :before pseudo element is the caption/text. Since the elements are independent of each other, you can use separate styling for more optimal positioning.

.image:after, .image:before {
    position: absolute;
    opacity: 0;
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
}
.image:after {
    content: '\A';
    width: 100%; height:100%;
    top: 0; left:0;
    background:rgba(0,0,0,0.6);
}
.image:before {
    content: attr(data-content);
    width: 100%;
    color: #fff;
    z-index: 1;
    bottom: 0;
    padding: 4px 10px;
    text-align: center;
    background: #f00;
    box-sizing: border-box;
    -moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
    opacity: 1;
}

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

Use a parameter array with the params modifier:

public static int AddUp(params int[] values)
{
    int sum = 0;
    foreach (int value in values)
    {
        sum += value;
    }
    return sum;
}

If you want to make sure there's at least one value (rather than a possibly empty array) then specify that separately:

public static int AddUp(int firstValue, params int[] values)

(Set sum to firstValue to start with in the implementation.)

Note that you should also check the array reference for nullity in the normal way. Within the method, the parameter is a perfectly ordinary array. The parameter array modifier only makes a difference when you call the method. Basically the compiler turns:

int x = AddUp(4, 5, 6);

into something like:

int[] tmp = new int[] { 4, 5, 6 };
int x = AddUp(tmp);

You can call it with a perfectly normal array though - so the latter syntax is valid in source code as well.

You can't pass str to your model fit() method. as it mentioned here

The training input samples. Internally, it will be converted to dtype=np.float32 and if a sparse matrix is provided to a sparse csc_matrix.

Try transforming your data to float and give a try to LabelEncoder.

On Windows 7 with Firefox 10, the cert8.db file is stored at %userprofile%\AppData\Roaming\Mozilla\Firefox\Profiles\########.default\cert8.db. If you are an administrator, you can probably write a simple WMI application to copy the file to the User's respective folder.

Also, a solution that worked for me from http://www.appdeploy.com/messageboards/tm.asp?m=52532&mpage=1&key=&#52532

1. Copied CERTUTIL.EXE from the NSS zip file ( http://www.mozilla.org/projects/security/pki/nss/tools/ ) to C:\Temp\CertImport (I also placed the certificates I want to import there)

2. Copied all the dll's from the NSS zip file to C\:Windows\System32

3. Created a BAT file in %Appdata%\mozilla\firefox\profiles with this script...

   Set FFProfdir=%Appdata%\mozilla\firefox\profiles 
   Set CERTDIR=C:\Temp\CertImport 
   DIR /A:D /B > "%Temp%\FFProfile.txt" 
   FOR /F "tokens=*" %%i in (%Temp%\FFProfile.txt) do ( 
   CD /d "%FFProfDir%\%%i" 
   COPY cert8.db cert8.db.orig /y 
   For %%x in ("%CertDir%\Cert1.crt") do "%Certdir%\certutil.exe" -A -n "Cert1" -i "%%x" -t "TCu,TCu,TCu" -d . 
   For %%x in ("%CertDir%\Cert2.crt") do "%Certdir%\certutil.exe" -A -n "Cert2" -i "%%x" -t "TCu,TCu,TCu" -d . 
   ) 
   DEL /f /q "%Temp%\FFProfile.txt" 
   

4. Executed the BAT file with good results.

Have a look at the Android developers page: http://developer.android.com/training/basics/fragments/communicating.html#DefineInterface

Basically, you define an interface in your Fragment A, and let your Activity implement that Interface. Now you can call the interface method in your Fragment, and your Activity will receive the event. Now in your activity, you can call your second Fragment to update the textview with the received value

Your Activity implements your interface (See FragmentA below)

public class YourActivity implements FragmentA.TextClicked{
    @Override
    public void sendText(String text){
        // Get Fragment B
        FraB frag = (FragB)
            getSupportFragmentManager().findFragmentById(R.id.fragment_b);
        frag.updateText(text);
    }
}

Fragment A defines an Interface, and calls the method when needed

public class FragA extends Fragment{

    TextClicked mCallback;

    public interface TextClicked{
        public void sendText(String text);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        // This makes sure that the container activity has implemented
        // the callback interface. If not, it throws an exception
        try {
            mCallback = (TextClicked) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                + " must implement TextClicked");
        }
    }

    public void someMethod(){
        mCallback.sendText("YOUR TEXT");
    }

    @Override
    public void onDetach() {
        mCallback = null; // => avoid leaking, thanks @Deepscorn
        super.onDetach();
    }
}

Fragment B has a public method to do something with the text

public class FragB extends Fragment{

    public void updateText(String text){
        // Here you have it
    }
}

Your question was already answered by the other posters, I'd just like to point out that

 delete from table where id <> 2

(or variants thereof, not id = 2 etc) will not delete rows where id is NULL.

If you also want to delete rows with id = NULL:

delete from table where id <> 2 or id is NULL

I think you could get away with using relative positioning and then set the top/left positioning of the second DIV until you have it in the position desired.

using return false in an onclick event stops the browser from processing the rest of the execution stack, which includes following the link in the href attribute.

In other words, adding return false stops the href from working. In your example, this is exactly what you want.

In buttons, it's not necessary because onclick is all it will ever execute -- there is no href to process and go to.

Assuming you are testing via mocha, you have to run your tests using the mocha command instead of the node executable.

So if you haven't already, make sure you do npm install mocha -g. Then just run mocha in your project's root directory.

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

Just leaving this here for future visitors:

In my case the /WEB-INF/classes directory was missing. If you are using Eclipse, make sure the .settings/org.eclipse.wst.common.component is correct (Deployment Assembly in the project settings).

In my case it was missing

    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>
    <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/test/resources"/>

This file is also a common source of errors as mentioned by Anuj (missing dependencies of other projects).

Otherwise, hopefully the other answers (or the "Problems" tab) will help you.

If you need to count a more complex query, with groupBy, having etc... You can borrow from Doctrine\ORM\Tools\Pagination\Paginator:

$paginator = new \Doctrine\ORM\Tools\Pagination\Paginator($query);
$totalRows = count($paginator);

@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.

.box {_x000D_
  width: 500px;_x000D_
  height: 100px;_x000D_
  border: solid 5px #000;_x000D_
  border-color: transparent transparent #000 transparent;_x000D_
  border-radius: 0 0 240px 50%/60px;_x000D_
}

<div class="box"></div>

well when i had these problem i faced 2 code errors

{!! Form::model(['method' => 'POST','route' => ['message.store']]) !!}

i corrected it by doing this

{!! Form::open(['method' => 'POST','route' => 'message.store']) !!}

so just to expatiate i changed the form model to open and also the route where wrongly placed in square braces.

I found the best way to send input is to use cat and a text file to pass along whatever input you need.

cat "input.txt" | ./Script.sh

Try delete:

models.User.query.delete()

From the docs: Returns the number of rows deleted, excluding any cascades.

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

It has to do with how the function is called- basically the order in which things are put on the the stack and who is responsible for cleanup.

Here's the documentation, but it doesn't mean much unless you understand the first part:
http://msdn.microsoft.com/en-us/library/zxk0tw93.aspx

I know I'm late to the party, but now there's a quick answer to this:

git fetch --prune --prune-tags # or just git fetch -p -P

Yes, it's now an option to fetch.

If you don't want to fetch, and just prune:

git remote prune origin

If the rows are immediately after each other then you can use a regex replace:

Search Pattern: ^(.*\r?\n)(\1)+

Replace with: \1

We can use concurrent collection classes to avoid ConcurrentModificationException while iterating over a collection, for example CopyOnWriteArrayList instead of ArrayList.

RENAME SPECIFIC COLUMNS

Use the df.rename() function and refer the columns to be renamed. Not all the columns have to be renamed:

df = df.rename(columns={'oldName1': 'newName1', 'oldName2': 'newName2'})
# Or rename the existing DataFrame (rather than creating a copy) 
df.rename(columns={'oldName1': 'newName1', 'oldName2': 'newName2'}, inplace=True)

Minimal Code Example

df = pd.DataFrame('x', index=range(3), columns=list('abcde'))
df

   a  b  c  d  e
0  x  x  x  x  x
1  x  x  x  x  x
2  x  x  x  x  x

The following methods all work and produce the same output:

df2 = df.rename({'a': 'X', 'b': 'Y'}, axis=1)  # new method
df2 = df.rename({'a': 'X', 'b': 'Y'}, axis='columns')
df2 = df.rename(columns={'a': 'X', 'b': 'Y'})  # old method  

df2

   X  Y  c  d  e
0  x  x  x  x  x
1  x  x  x  x  x
2  x  x  x  x  x

Remember to assign the result back, as the modification is not-inplace. Alternatively, specify inplace=True:

df.rename({'a': 'X', 'b': 'Y'}, axis=1, inplace=True)
df

   X  Y  c  d  e
0  x  x  x  x  x
1  x  x  x  x  x
2  x  x  x  x  x
 

From v0.25, you can also specify errors='raise' to raise errors if an invalid column-to-rename is specified. See v0.25 rename() docs.

REASSIGN COLUMN HEADERS

Use df.set_axis() with axis=1 and inplace=False (to return a copy).

df2 = df.set_axis(['V', 'W', 'X', 'Y', 'Z'], axis=1, inplace=False)
df2

   V  W  X  Y  Z
0  x  x  x  x  x
1  x  x  x  x  x
2  x  x  x  x  x

This returns a copy, but you can modify the DataFrame in-place by setting inplace=True (this is the default behaviour for versions <=0.24 but is likely to change in the future).

You can also assign headers directly:

df.columns = ['V', 'W', 'X', 'Y', 'Z']
df

   V  W  X  Y  Z
0  x  x  x  x  x
1  x  x  x  x  x
2  x  x  x  x  x
