Also, If you are new and you are not using T4MVC, then I would recommend you to use it!

It gives you intellisence for actions,Controllers,views etc (no more magic strings)

When importing an existing Gradle project (one with a build.gradle) into IntelliJ IDEA, when presented with the following screen, select Import from external model -> Gradle.

Optionally, select Auto Import on the next screen to automatically import new dependencies.

You're already doing it!

save() will check if something in the model has changed. If it hasn't it won't run a db query.

Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate:

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}

The getDirty() method simply compares the current attributes with a copy saved in original when the model is created. This is done in the syncOriginal() method:

public function __construct(array $attributes = array())
{
    $this->bootIfNotBooted();

    $this->syncOriginal();

    $this->fill($attributes);
}

public function syncOriginal()
{
    $this->original = $this->attributes;

    return $this;
}

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}

Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

Lets look at ways to reference the image.

Back a directory

../

Folder in a directory:

 foldername/

File in a directory

 imagename.jpg

Now, lets combine them with the addresses you specified.

 /Resources/views/Default/index.html
 /Resources/public/images/iwojimaflag.jpg

The first common directory referenced from the html file is three back:

 ../../../

It is in within two folders in that:

 ../../../public/images/

And you've reached the image:

 ../../../public/images/iwojimaflag.jpg

Note: This is assuming you are accessing a page at domain.com/Resources/views/Default/index.html as you specified in your comment.

<?php

$data_string = json_encode($data);

Use below script to get back to normal 1 plot:

For swift 3 and 4, you can do this. Good practice is set name of Storyboard equal to StoryboardID.

enum StoryBoardName{
   case second = "SecondViewController"
}
extension UIStoryBoard{
   class func load(_ storyboard: StoryBoardName) -> UIViewController{
      return UIStoryboard(name: storyboard.rawValue, bundle: nil).instantiateViewController(withIdentifier: storyboard.rawValue)
   }
}

and then you can load your Storyboard in your ViewController like this:

class MyViewController: UIViewController{
     override func viewDidLoad() {
        super.viewDidLoad()
        guard let vc = UIStoryboard.load(.second) as? SecondViewController else {return}
        self.present(vc, animated: true, completion: nil)
     }

}

When you create a new Storyboard just set the same name on StoryboardID and add Storyboard name in your enum "StoryBoardName"

I had to write this in the Immediate window :3

Just use:

Example:

StringBuilder randSB = new StringBuilder("just a String");
System.out.println(randSB.getClass().getSimpleName());

Output:

Haha, Lovely - let me also include my version of stackPusher's code :). We are using this functionality in C#. Works fine for all Excel ranges.:

public static String ConvertToLiteral(int number)
{
        int firstLetter = (((number - 27) / (26 * 26))) % 26;
        int middleLetter = ((((number - 1) / 26)) % 26);

        int lastLetter = (number % 26);
        firstLetter = firstLetter == 0 ? 26 : firstLetter;
        middleLetter = middleLetter == 0 ? 26 : middleLetter;
        lastLetter = lastLetter == 0 ? 26 : lastLetter;
        String returnedString = "";
        returnedString = number > 27 * 26 ? (Convert.ToChar(firstLetter + 64).ToString()) : returnedString;
        returnedString += number > 26 ? (Convert.ToChar(middleLetter + 64).ToString()) : returnedString;
        returnedString += lastLetter >= 0 ? (Convert.ToChar(lastLetter + 64).ToString()) : returnedString;
        return returnedString;
}

Linux & Windows (WSL)

When using the Windows Subsystem for Linux (e.g. Ubuntu/Debian on WSL) the xclip solution won't work. Instead you need to use clip.exe and powershell.exe to copy into and paste from the Windows clipboard.

.bashrc

This solution works on "real" Linux-based systems (i.e. Ubuntu, Debian) as well as on WSL systems. Just put the following code into your .bashrc:

if grep -q -i microsoft /proc/version; then
    # on WSL
    alias copy="clip.exe"
    alias paste="powershell.exe Get-Clipboard"
else
    # on "normal" linux
    alias copy="xclip -sel clip"
    alias paste="xclip -sel clip -o"
fi

How it works

The file /proc/version contains information about the currently running OS. When the system is running in WSL mode, then this file additionally contains the string Microsoft which is checked by grep.

Usage

To copy:

cat file | copy

And to paste:

paste > new_file

If we are use chosen dropdown list, then we can use below css(No JS/JQuery require)

The best way for me was using vector with categories in order I need as limits parameter to scale_x_discrete. I think it is pretty simple and straightforward solution.

ggplot(mtcars, aes(factor(cyl))) + 
  geom_bar() + 
  scale_x_discrete(limits=c(8,4,6))

FatJar can help you in this case.

In addition to the"Export as Jar" function which is included to Eclipse the Plug-In bundles all dependent JARs together into one executable jar.
The Plug-In adds the Entry "Build Fat Jar" to the Context-Menu of Java-projects

This is useful if your final exported jar includes other external jars.

If you have Ganymede, the Export Jar dialog is enough to export your resources from your project.

After Ganymede, you have:

I had the same problem today with the addition "Return code is: 400, ReasonPhrase: Bad Request." which turned out to be the "artifact is already deployed with that version if it is a release" problem from answer above enter link description here

One solution not mentioned yet is to configure Nexus to allow redeployment into a Release repository. Maybe not a best practice, because this is set for a reason, you nevertheless could go to "Access Settings" in your Nexus repositories´ "Configuration"-Tab and set the "Deployment Policy" to "Allow Redeploy".

Same thing, Just start the table name with # or ##:

CREATE TABLE #TemporaryTable          -- Local temporary table - starts with single #
(
    Col1 int,
    Col2 varchar(10)
    ....
);

CREATE TABLE ##GlobalTemporaryTable   -- Global temporary table - note it starts with ##.
(
    Col1 int,
    Col2 varchar(10)
    ....
);

Temporary table names start with # or ## - The first is a local temporary table and the last is a global temporary table.

Here is one of many articles describing the differences between them.

Try adding parentheses around the row in table1 e.g.

DELETE 
  FROM table1
 WHERE (stn, year(datum)) IN (SELECT stn, jaar FROM table2);

The above is Standard SQL-92 code. If that doesn't work, it could be that your SQL product of choice doesn't support it.

Here's another Standard SQL approach that is more widely implemented among vendors e.g. tested on SQL Server 2008:

MERGE INTO table1 AS t1
   USING table2 AS s1
      ON t1.stn = s1.stn
         AND s1.jaar = YEAR(t1.datum)
WHEN MATCHED THEN DELETE;

Most windows users won't have that font on their computers. Also, you can't just submit it to your server and call it using font-face because this isn't a free font...

And last, but not least, answering the question that nobody mentioned yet, Helvetica and Helvetica Neue do not render well on screen unless they have a really big font-size. You'll find a lot of pages using this font, and in all of them you'll see that the top border of a line of text looks wavy and that some letters look taller than others. In my opinion this is the main reason why you shouldn't use it. There are other options for you to use, like Open Sans.

If anyone else is having a nullptr on the searchview variable, I found out that the item setup is a tiny bit different:

old:

android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView"

new:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="androidx.appcompat.widget.SearchView"

pre-android x:

app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"

For more information, it's updated documentation is located here.

The practical difference is binding strength, which can lead to peculiar behavior if you're not prepared for it:

foo = :foo
bar = nil

a = foo and bar
# => nil
a
# => :foo

a = foo && bar
# => nil
a
# => nil

a = (foo and bar)
# => nil
a
# => nil

(a = foo) && bar
# => nil
a
# => :foo

The same thing works for || and or.

Seems like you posted a new question after you realized that you were dealing with a simpler problem related to size_t. I am glad that you did.

Anyways, You have a .c source file, and most of the code looks as per C standards, except that #include <iostream> and using namespace std;

C equivalent for the built-in functions of C++ standard #include<iostream> can be availed through #include<stdio.h>

1. Replace #include <iostream> with #include <stdio.h>, delete using namespace std;

2. With #include <iostream> taken off, you would need a C standard alternative for cout << endl;, which can be done by printf("\n"); or putchar('\n');
   Out of the two options, printf("\n"); works the faster as I observed.

   When used printf("\n"); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.031s
   user    0m0.030s
   sys     0m0.030s
   

   When used putchar('\n'); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.047s
   user    0m0.030s
   sys     0m0.030s

With sdk, you can't write to the root of internal storage. This cause your error.

Edit :

Based on your code, to use internal storage with sdk:

final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

I do it like this, to launch the SendFreeTextActivity from a (custom) menu fragment that appears in multiple activities:

    final Button sendFreeTextButton = (Button) view.findViewById(R.id.sendFreeTextButton);
    sendFreeTextButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Log.d(TAG, "sendFreeTextButton clicked");
            Intent intent = new Intent(getActivity(), SendFreeTextActivity.class);
            MenuFragment.this.startActivity(intent);
        }
    });

\ is used as for escape sequence in many programming languages, including Java.

If you want to

• go to next line then use \n or \r,
• for tab use \t
• likewise to print a \ or " which are special in string literal you have to escape it with another \ which gives us \\ and \"

Just an FYI for answer Replacing characters in Ant property - if you are trying to use this inside of a maven execution, you can't reference maven variables directly. You will need something like this:

Since ffmpeg transpose command is very slow, use the command below to rotate a video by 90 degrees clockwise.

Fast command (Without encoding)-

ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=270 output.mp4

For full video encoding (Slow command, does encoding)

ffmpeg -i inputFile -vf "transpose=1" -c:a copy outputFile

For what it's worth I do miss the ^ operator when raising a power of 2 to define a binary constant. Can't use Math.Pow() there, but shifting an unsigned int of 1 to the left by the exponent's value works. When I needed to define a constant of (2^24)-1:

public static int Phase_count = 24;
public static uint PatternDecimal_Max = ((uint)1 << Phase_count) - 1;

Remember the types must be (uint) << (int).

To view the files just browse them from the command prompt (cmd), eg.:

c:\>cd \Windows\assembly\GAC_32
c:\Windows\assembly\GAC_32> dir

To add and remove files from the GAC use the tool gacutil

Try this:

$('input[name=Comanda]')
.click(
     function ()
     {
         $(this).hide();
     }
);

For doing everything else you can use something like this one:

$('input[name=Comanda]')
.click(
     function ()
     {
         $(this).hide();

         $(".ClassNameOfShouldBeHiddenElements").hide();
     }
);

For hidding any other elements based on their IDs, use this one:

$('input[name=Comanda]')
.click(
     function ()
     {
         $(this).hide();

         $("#FirstElement").hide();
         $("#SecondElement").hide();
         $("#ThirdElement").hide();
     }
);

You can implicitly convert between numerical types, even when that loses precision:

char c = i;

However, you might like to enable compiler warnings to avoid potentially lossy conversions like this. If you do, then use static_cast for the conversion.

Of the other casts:

• dynamic_cast only works for pointers or references to polymorphic class types;
• const_cast can't change types, only const or volatile qualifiers;
• reinterpret_cast is for special circumstances, converting between pointers or references and completely unrelated types. Specifically, it won't do numeric conversions.
• C-style and function-style casts do whatever combination of static_cast, const_cast and reinterpret_cast is needed to get the job done.

 (from p in context.ParentTable     
  join c in context.ChildTable 
    on p.ParentId equals c.ChildParentId into j1 
  from j2 in j1.DefaultIfEmpty() 
     select new { 
          ParentId = p.ParentId,
         ChildId = j2==null? 0 : 1 
      })
   .GroupBy(o=>o.ParentId) 
   .Select(o=>new { ParentId = o.key, Count = o.Sum(p=>p.ChildId) })

(ps - I couldn't comment) I think your best bet is something like you've done, or similar to:

$user = User::where('mobile', Input::get('mobile'));
$user->exists() and $user = $user->first();

Oh, also: count() instead if exists but this could be something used after get.

To use default value from any column of table. then you must need to define @DynamicInsert as true or else you just define @DynamicInsert. Because hibernate takes by default as a true. Consider as the given example:

@AllArgsConstructor
@Table(name = "core_contact")
@DynamicInsert
public class Contact implements Serializable {

    @Column(name = "status", columnDefinition = "int default 100")
    private Long status;

}

The solutions of Fabricio works just fine.

A very common usecase of calc is add 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable: 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);
width: -o-calc(~"100% - "@someMarginVariable*2);

Or can use a mixin like:

.fullWidthMinusMarginPaddingMixin(@marginSize,@paddingSize) {
  @minusValue: (@marginSize+@paddingSize)*2;
  padding: @paddingSize;
  margin: @marginSize;
  width: calc(~"100% - "@minusValue);
  width: -moz-calc(~"100% - "@minusValue);
  width: -webkit-calc(~"100% - "@minusValue);
  width: -o-calc(~"100% - "@minusValue);
}

As far as the compiler is concerned, those two methods are identical. There will be one implementation of both.

This isn't a problem if the two methods are effectively identical, in that they should have the same implementation. If they are contractually different (as per the documentation for each interface), you'll be in trouble.

To add to the previous explanations, static method calls are bound to a specific method at compile-time, which rather rules out polymorphic behavior.

Wanna a list of folder in xampp?

Just delete or change the file index.php to index.txt. And you will get the list just typing url: localhost.

This object variable will append style tag to the head tag with type attribute and one simple transition rule inside that matches every single id/class/element. Feel free to modify content property and inject as many rules as you need. Just make sure that css rules inside content remain in one line (or 'escape' each new line, if You prefer so).

var script = {

  type: 'text/css', style: document.createElement('style'), 
  content: "* { transition: all 220ms cubic-bezier(0.390, 0.575, 0.565, 1.000); }",
  append: function() {

    this.style.type = this.type;
    this.style.appendChild(document.createTextNode(this.content));

If the tables are innodb you can create it like this:

CREATE TABLE accounts(
    account_id INT NOT NULL AUTO_INCREMENT,
    customer_id INT( 4 ) NOT NULL ,
    account_type ENUM( 'savings', 'credit' ) NOT NULL,
    balance FLOAT( 9 ) NOT NULL,
    PRIMARY KEY ( account_id ), 
    FOREIGN KEY (customer_id) REFERENCES customers(customer_id) 
) ENGINE=INNODB;

You have to specify that the tables are innodb because myisam engine doesn't support foreign key. Look here for more info.

First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:

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

x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]

fig.show()

tstart = time.time()
for i in xrange(1, 20):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    fig.canvas.draw()

print 'FPS:' , 20/(time.time()-tstart)

With the above example, I get around 10fps.

Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.

However, there are a lot of things you can do to speed this example up.

There are two main reasons why this is as slow as it is.

1) Calling fig.canvas.draw() redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.

2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.

Both these can be fixed by using blitting.

To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.

However, without knowing a bit more about what you're doing, I can't help you there.

Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

fig.show()

# We need to draw the canvas before we start animating...
fig.canvas.draw()

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]

tstart = time.time()
for i in xrange(1, 2000):
    items = enumerate(zip(lines, axes, backgrounds), start=1)
    for j, (line, ax, background) in items:
        fig.canvas.restore_region(background)
        line.set_ydata(np.sin(j*x + i/10.0))
        ax.draw_artist(line)
        fig.canvas.blit(ax.bbox)

print 'FPS:' , 2000/(time.time()-tstart)

This gives me ~200fps.

To make this a bit more convenient, there's an animations module in recent versions of matplotlib.

As an example:

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

x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)

fig, axes = plt.subplots(nrows=6)

styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
    return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]

def animate(i):
    for j, line in enumerate(lines, start=1):
        line.set_ydata(np.sin(j*x + i/10.0))
    return lines

# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200), 
                              interval=0, blit=True)
plt.show()

this will sort it for you

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

    Button but1=(Button)findViewById(R.id.button1);

    but1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent int1= new Intent(MainActivity.this,xxactivity.class);
            startActivity(int1);
        }
    });
}

You just need to amend the xxactivity to the name of your second activity

Similar to Lukazoid's answer I've created an extension for IQueryable.

   public static IEnumerable<IEnumerable<T>> PageIterator<T>(this IQueryable<T> source, int pageSize)
            {
                Contract.Requires(source != null);
                Contract.Requires(pageSize > 0);
                Contract.Ensures(Contract.Result<IEnumerable<IQueryable<T>>>() != null);

                using (var enumerator = source.GetEnumerator())
                {
                    while (enumerator.MoveNext())
                    {
                        var currentPage = new List<T>(pageSize)
                        {
                            enumerator.Current
                        };

                        while (currentPage.Count < pageSize && enumerator.MoveNext())
                        {
                            currentPage.Add(enumerator.Current);
                        }
                        yield return new ReadOnlyCollection<T>(currentPage);
                    }
                }
            }

It is useful if Skip or Take are not supported.

Yes - this is possible. In order to do it, you need to assign a tabindex...

<div tabindex="0">Hello World</div>

A tabindex of 0 will put the tag "in the natural tab order of the page". A higher number will give it a specific order of priority, where 1 will be the first, 2 second and so on.

You can also give a tabindex of -1, which will make the div only focus-able by script, not the user.

document.getElementById('test').onclick = function () {_x000D_
    document.getElementById('scripted').focus();_x000D_
};

div:focus {_x000D_
    background-color: Aqua;_x000D_
}

<div>Element X (not focusable)</div>_x000D_
<div tabindex="0">Element Y (user or script focusable)</div>_x000D_
<div tabindex="-1" id="scripted">Element Z (script-only focusable)</div>_x000D_
<div id="test">Set Focus To Element Z</div>

Obviously, it is a shame to have an element you can focus by script that you can't focus by other input method (especially if a user is keyboard only or similarly constrained). There are also a whole bunch of standard elements that are focusable by default and have semantic information baked in to assist users. Use this knowledge wisely.

If you want to pickle your modified dictionary, you need to add few state methods to above answers:

class DotDict(dict):
    """dot.notation access to dictionary attributes"""
    def __getattr__(self, attr):
        return self.get(attr)
    __setattr__= dict.__setitem__
    __delattr__= dict.__delitem__

    def __getstate__(self):
        return self

    def __setstate__(self, state):
        self.update(state)
        self.__dict__ = self

check this

 list = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20]

 list[0:10]

Outputs:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I had a similar issue. Renato's tip worked for me. I used a older version of java class files (under WEB-INF/classes folder) and the problem disappeared. So, it should have been the compiler version mismatch.

Here's a jQuery version based on the answer by @takrl and @tom above. Note: no hardcoded formid (named aspnetForm above) and also does not use direct form.target references which Firefox may find problematic:

<asp:Button ID="btnSubmit" OnClientClick="openNewWin();"  Text="Submit" OnClick="btn_OnClick" runat="server"/>

Then in your js file referenced on the SAME page:

function openNewWin () {
    $('form').attr('target','_blank');
    setTimeout('resetFormTarget()', 500);
}

function resetFormTarget(){
    $('form').attr('target','');
}

If the path in Ubuntu is "/home/ec2-user/Name of Directory", then do this:

1) Java's build.properties file:

build_path='/home/ec2-user/Name\\ of\\ Directory'

Where ~/ is equal to /home/ec2-user

2) Jenkinsfile:

build_path=buildprops['build_path']
echo "Build path= ${build_path}"
sh "cd ${build_path}"

If you are using Firefox, alert(object.toSource()) should suffice for simple debugging purposes.

This is by far the easiest example I have found on the net. http://jonraasch.com/blog/a-simple-jquery-slideshow

Summaring the example, this is what you need to do a slideshow:

HTML:

<div id="slideshow">
    <img src="img1.jpg" style="position:absolute;" class="active" />
    <img src="img2.jpg" style="position:absolute;" />
    <img src="img3.jpg" style="position:absolute;" />
</div>

Position absolute is used to put an each image over the other.

CSS

<style type="text/css">
    .active{
        z-index:99;
    }
</style>

The image that has the class="active" will appear over the others, the class=active property will change with the following Jquery code.

<script>
    function slideSwitch() {
        var $active = $('div#slideshow IMG.active');
        var $next = $active.next();    

        $next.addClass('active');

        $active.removeClass('active');
    }

    $(function() {
        setInterval( "slideSwitch()", 5000 );
    });
</script>

If you want to go further with slideshows I suggest you to have a look at the link above (to see animated oppacity changes - 2n example) or at other more complex slideshows tutorials.

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

To totally avoid using CMAKE, you can simply:

1. Build your project as you normally with Make through the terminal.

2. Change your CLion configurations, go to (in top bar) :
   Run -> Edit Configurations -> yourProjectFolder

3. Change the Executable to the one generated with Make

4. Change the Working directory to the folder holding your executable (if needed)

5. Remove the Build task in the Before launch:Activate tool window box

And you're all set! You can now use the debug button after your manual build.

To filter an array irrespective of the property type (i.e. for all property types), we can create a custom filter pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({ name: "filter" })
export class ManualFilterPipe implements PipeTransform {
  transform(itemList: any, searchKeyword: string) {
    if (!itemList)
      return [];
    if (!searchKeyword)
      return itemList;
    let filteredList = [];
    if (itemList.length > 0) {
      searchKeyword = searchKeyword.toLowerCase();
      itemList.forEach(item => {
        //Object.values(item) => gives the list of all the property values of the 'item' object
        let propValueList = Object.values(item);
        for(let i=0;i<propValueList.length;i++)
        {
          if (propValueList[i]) {
            if (propValueList[i].toString().toLowerCase().indexOf(searchKeyword) > -1)
            {
              filteredList.push(item);
              break;
            }
          }
        }
      });
    }
    return filteredList;
  }
}

//Usage

//<tr *ngFor="let company of companyList | filter: searchKeyword"></tr>

Don't forget to import the pipe in the app module

We might need to customize the logic to filer with dates.

One way to test private methods is through reflection. This applies to NUnit and XUnit, too:

MyObject objUnderTest = new MyObject();
MethodInfo methodInfo = typeof(MyObject).GetMethod("SomePrivateMethod", BindingFlags.NonPublic | BindingFlags.Instance);
object[] parameters = {"parameters here"};
methodInfo.Invoke(objUnderTest, parameters);

[host_group]
host-1 ansible_ssh_host=192.168.0.21 node_name=foo
host-2 ansible_ssh_host=192.168.0.22 node_name=bar

[host_group:vars]
custom_var=asdasdasd

You can access host group vars using:

{{ hostvars['host_group'].custom_var }}

If you need a specific value from specific host, you can use:

{{ hostvars[groups['host_group'][0]].node_name }}

This code worked nicely for me, thanks.

This is what i did with it. Some methods for stepping forward or backwards and one for going directly to a particular page. Its for a 6 page document in portrait view. It will work ok if you paste it into the implementation of the RootController of the pageViewController template.

-(IBAction)pageGoto:(id)sender {

    //get page to go to
    NSUInteger pageToGoTo = 4;

    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers   objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //get the page(s) to go to
    DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo - 1) storyboard:self.storyboard];

    DataViewController *secondPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo) storyboard:self.storyboard];

    //put it(or them if in landscape view) in an array
    NSArray *theViewControllers = nil;    
    theViewControllers = [NSArray arrayWithObjects:targetPageViewController, secondPageViewController, nil];


    //check which direction to animate page turn then turn page accordingly
    if (retreivedIndex < (pageToGoTo - 1) && retreivedIndex != (pageToGoTo - 1)){
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
    }

    if (retreivedIndex > (pageToGoTo - 1) && retreivedIndex != (pageToGoTo - 1)){
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];
    }

}


-(IBAction)pageFoward:(id)sender {

    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //check that current page isn't first page
    if (retreivedIndex < 5){

        //get the page to go to
        DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(retreivedIndex + 1) storyboard:self.storyboard];

        //put it(or them if in landscape view) in an array
        NSArray *theViewControllers = nil;    
        theViewControllers = [NSArray arrayWithObjects:targetPageViewController, nil];

        //add page view
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

    }

}


-(IBAction)pageBack:(id)sender {


    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //check that current page isn't first page
    if (retreivedIndex > 0){

    //get the page to go to
    DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(retreivedIndex - 1) storyboard:self.storyboard];

    //put it(or them if in landscape view) in an array
    NSArray *theViewControllers = nil;    
    theViewControllers = [NSArray arrayWithObjects:targetPageViewController, nil];

    //add page view
    [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];

    }

}

it turns out I was mistaken.

Solution is: in anaconda (as well as in other implementations), set the path environment variable to the directory where 'python.exe' is installed.

As a default, the python.exe file in anaconda is in:

c:\.....\anaconda

after you do that, obviously, the python command works, in my case, yielding the following.

python
Python 3.4.3 |Anaconda 2.2.0. (64|bit)|(default, Nov 7 2015), etc, etc

I think its possible provided if it is a serial data in broadcasting method. but you will not be able to transfer any voice/audio data to the other slave device. As per Bluetooth 4.0, the protocol does not support this. However there is a improvement going on to broadcast the audio/voice data.

Outline: Create two elements: a slider/switch and a trough as a parent of the slider. To toggle the state, switch the slider element between an "on" and an "off" class. In the style for one class, set "left" to 0 and leave "right" the default; for the other class, do the opposite:

<style type="text/css">
.toggleSwitch {
    width: ...;
    height: ...;
    /* add other styling as appropriate to position element */
    position: relative;
}
.slider {
    background-image: url(...);
    position: absolute;
    width: ...;
    height: ...;
}
.slider.on {
    right: 0;
}
.slider.off {
    left: 0;
}
</style>
<script type="text/javascript">
function replaceClass(elt, oldClass, newClass) {
    var oldRE = RegExp('\\b'+oldClass+'\\b');
    elt.className = elt.className.replace(oldRE, newClass);
}
function toggle(elt, on, off) {
    var onRE = RegExp('\\b'+on+'\\b');
    if (onRE.test(elt.className)) {
        elt.className = elt.className.replace(onRE, off);
    } else {
        replaceClass(elt, off, on);
    }
}
</script>
...
<div class="toggleSwitch" onclick="toggle(this.firstChild, 'on', 'off');"><div class="slider off" /></div>

Alternatively, just set the background image for the "on" and "off" states, which is a much easier approach than mucking about with positioning.

@dibrovsd: Solution will not work if the xml have more than one tag with same name

On your line of thought, I have modified the code a bit and written it for general node instead of root:

from collections import defaultdict
def xml2dict(node):
    d, count = defaultdict(list), 1
    for i in node:
        d[i.tag + "_" + str(count)]['text'] = i.findtext('.')[0]
        d[i.tag + "_" + str(count)]['attrib'] = i.attrib # attrib gives the list
        d[i.tag + "_" + str(count)]['children'] = xml2dict(i) # it gives dict
     return d

I tried to do the same as you, but apparently the backgroundImage doesn't work with encoded data. As an alternative, I suggest to use CSS classes and the change between those classes.

If you are generating the data "on the fly" you can load the CSS files dynamically.

CSS:

.backgroundA {
    background-image: url("data:image/png;base64,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");

For the record, be advised that all of the above is (still) true only if the AJAX call is made on the same domain. If you're looking into setting cookies on another domain using AJAX, you're opening a totally different can of worms. Reading cross-domain cookies does work, however (or at least the server serves them; whether your client's UA allows your code to access them is, again, a different topic; as of 2014 they do).

Yes, presumably it wants the path to the javadoc command line tool that comes with the JDK (in the bin directory, same as java and javac).

Eclipse should be able to find it automatically; are you perhaps running it on a JRE? That would explain the request.

You have the alias inside of the case, it needs to be outside of the END:

Insert into TblStuff (FullName,Address,City,Zip)
Select
  Case
    When Middle is Null 
    Then Fname + LName
    Else Fname +' ' + Middle + ' '+ Lname
  End as FullName,
  Case
    When Address2 is Null Then Address1
    else Address1 +', ' + Address2 
  End as  Address,
  City as City,
  Zip as Zip
from tblImport

var test = [
  {id:1, test: 1},
  {id:2, test: 2},
  {id:2, test: 2}
];

var result = test.findIndex(findIndex, '2');

console.log(result);

function findIndex(object) {
  return object.id == this;
}

will return index 1 (Works only in ES 2016)

print Cast('1/1/' + cast(datepart(yyyy, getdate()) as nvarchar(4)) as date)

I consider this simpler than any prior correct answer. I'll also throw in javadoc. :-)

/**
 * Converts the given string to title case, where the first
 * letter is capitalized and the rest of the string is in
 * lower case.
 * 
 * @param s a string with unknown capitalization
 * @return a title-case version of the string
 */
public static String toTitleCase(String s)
{
    if (s.isEmpty())
    {
        return s;
    }
    return s.substring(0, 1).toUpperCase() + s.substring(1).toLowerCase();
}

Strings of length 1 do not needed to be treated as a special case because s.substring(1) returns the empty string when s has length 1.

Set below code in RouteConfig.cs in App_Start folder

public static void RegisterRoutes(RouteCollection routes)
{
 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 routes.MapRoute(
 name: "Default",
 url: "{controller}/{action}/{id}",
 defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}

IF still not working then do below steps

Second Way : You simple follow below steps,

1) Right click on your Project

2) Select Properties

3) Select Web option and then Select Specific Page (Controller/View) and then set your login page

Here, Account is my controller and Login is my action method (saved in Account Controller)

Please take a look attached screenshot.

If you are like me, then you might have started with a Class Library, and then switched this to a Console Application. If so, change this...

namespace ClassLibrary1
{
    public class Class1
    {
    }
}

To this...

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
        }
    }
}

xml:space="preserve"

Works like a charm.

Edit: Wrong. Actually, it only works when the content is comprised of white spaces only.

The && and || operators "short-circuit", meaning they don't evaluate the right-hand side if it isn't necessary.

The & and | operators, when used as logical operators, always evaluate both sides.

There is only one case of short-circuiting for each operator, and they are:

• false && ... - it is not necessary to know what the right-hand side is because the result can only be false regardless of the value there
• true || ... - it is not necessary to know what the right-hand side is because the result can only be true regardless of the value there

Let's compare the behaviour in a simple example:

public boolean longerThan(String input, int length) {
    return input != null && input.length() > length;
}

public boolean longerThan(String input, int length) {
    return input != null & input.length() > length;
}

The 2nd version uses the non-short-circuiting operator & and will throw a NullPointerException if input is null, but the 1st version will return false without an exception.

Same issue, go to App Store and update Xcode

Off the top of my head, no.

I think the best you could do is something like this:

def loop(f,n):
    for i in xrange(n): f()

loop(lambda: <insert expression here>, 5)

But I think you can just live with the extra i variable.

Here is the option to use the _ variable, which in reality, is just another variable.

for _ in range(n):
    do_something()

Note that _ is assigned the last result that returned in an interactive python session:

>>> 1+2
3
>>> _
3

For this reason, I would not use it in this manner. I am unaware of any idiom as mentioned by Ryan. It can mess up your interpreter.

>>> for _ in xrange(10): pass
...
>>> _
9
>>> 1+2
3
>>> _
9

And according to Python grammar, it is an acceptable variable name:

identifier ::= (letter|"_") (letter | digit | "_")*

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

netcat (nc.exe) is the right tool. I have a feeling that any tool that does what you want it to do will have exactly the same problem with your antivirus software. Just flag this program as "OK" in your antivirus software (how you do this will depend on what type of antivirus software you use).

Of course you will also need to configure your sysadmin to accept that you're not trying to do anything illegal...

Use this

if (sizeof($arr) > 1) {
     ....
}

Or

if (count($arr) > 1) {
     ....
}

sizeof() is an alias for count(), they work the same.

Edit: Answering the second part of the question: The two lines of codes in the question are not alternative methods, they perform different functions. The first checks if the value at $arr['1'] is set, while the second returns the number of elements in the array.

This is my Df contain 4 is repeated twice so here will remove repeated values.

|    1|
|    4|

|    5|
|    4|

scala> val newdf=df.dropDuplicates

scala> newdf.show

|    1|
|    3|
|    5|
|    4|

As m3u8x is only available for windows. Once you have identified the m3u8 url you can also use Jdownloader2 or VLC Media Player to download and concatenate the stream.

Jdownloader2: Just copy the m3u8 url when it the Jdownloader is open. It will recognize the stream in Linkgrabber tab.

VLC 3:

Open Network -> Paste m3u8 url -> Checkmark Streamoutput -> Select Settings. Choose output file, container , video and audio encoding. (e.g output.mp4, container: mpeg4, video: h264, audio: mp4a) Start Stream. It will not play the video, but encode it, showing the encoding progress by moving the video play back progress bar.

WARNING: Previously suggesteed chrome extension Stream Video Downloader contains malware. See reddit post

Why are they using <i> tag to display icons ?

Because it is:

• Short
• i stands for icon (although not in HTML)

Is it not a bad practice ?

Awful practice. It is a triumph of performance over semantics.

Remove NodeJs and npm in your system and reinstall it by following commands

Uninlstallation

sudo apt remove nodejs
sudo apt remove npm

Fresh Installation

sudo apt install nodejs
sudo apt install npm

Configuration optional, in some cases users may face permission errors.

1. user defined directory where npm will install packages

   mkdir ~/.npm-global

2. configure npm

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

3. add directory to path

   echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.profile

4. refresh path for the current session

   source ~/.profile

5. cross-check npm and node modules installed successfully in our system

   node -v
npm -v

Installation of npx

sudo npm i -g npx
npx -v

Well-done we are ready to go... now you can easily use npx anywhere in your system.

What about

$.ajax({
  type: 'POST',
  url: $("form").attr("action"),
  data: $("form").serialize(), 
  //or your custom data either as object {foo: "bar", ...} or foo=bar&...
  success: function(response) { ... },
});

One can simply use the pydoc.locate function.

from pydoc import locate
my_class = locate("module.submodule.myclass")
instance = my_class()

Yeah I think the best way to transparent the background colour (make opacity only for the background) is using

.style{
        background-color: rgba(100, 100, 100, 0.5);
}

Above statement 0.5 is the opacity value.

It only apply the opacity changes to the background colour (not all elements')

The "opacity" attribute in the CSS will transparent all the elements in the block.

Maybe what comes from the server is already evaluated as JSON object? For example, using jQuery get method:

$.get('/service', function(data) {  
  var obj = data;

      /* 
         "obj" is evaluated at this point if server responded 
         with "application/json" or similar.
       */
      for (var i = 0; i < obj.length; i++) {
        console.log(obj[i].Name);
      }
    });

Alternatively, if you need to turn JSON object into JSON string literal, you can use JSON.stringify:

var json = [{"Id":"10","Name":"Matt"},{"Id":"1","Name":"Rock"}];
var jsonString = JSON.stringify(json);

But in this case I don't understand why you can't just take the json variable and refer to it instead of stringifying and parsing.

img{
    max-width:100%;
    object-fit: scale-down;
}

works for me. It scales down larger images to fit in the box, but leaves smaller images their original size.

You can check for empty string (when stderr is empty)

- name: Check script
  shell: . {{ venv_name }}/bin/activate && myscritp.py
  args:
    chdir: "{{ home }}"
  sudo_user: "{{ user }}"
  register: test_myscript

- debug: msg='myscritp is Ok'
  when: test_myscript.stderr == ""

If you want to check for fail:

- debug: msg='myscritp has error: {{test_myscript.stderr}}'
  when: test_myscript.stderr != ""

Also look at this stackoverflow question

To request a new password for the postgres user (without showing it in the command):

sudo -u postgres psql -c "\password"

I've tested this using the following powershell script and using (,) between the addresses. It worked for me!

$EmailFrom = "<[email protected]>";
$EmailPassword = "<password>";
$EmailTo = "<[email protected]>,<[email protected]>";
$SMTPServer = "<smtp.server.com>";
$SMTPPort = <port>;
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer,$SMTPPort);
$SMTPClient.EnableSsl = $true;
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom, $EmailPassword);
$Subject = "Notification from XYZ";
$Body = "this is a notification from XYZ Notifications..";
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body);

Try This :

**ob_start();**

include('header.php');

$name = $_POST['name'];
$score = $_POST['score'];
$dept = $_POST['dept'];

$MyDB->prep("INSERT INTO demo (`id`,`name`,`score`,`dept`, `date`) VALUES ('','$name','$score','$dept','$date')");
// Bind a value to our :id hook
// Produces: SELECT * FROM demo_table WHERE id = '23'
$MyDB->bind(':date', $date);
// Run the query
$MyDB->run();

header('Location:index.php');

**ob_end_flush();**

    exit;

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

use simplejson or cjson for speedups

import simplejson as json

json.loads(obj)

or 

cjson.decode(obj)

This seems to be very easy

>>> from mimetypes import MimeTypes
>>> import urllib 
>>> mime = MimeTypes()
>>> url = urllib.pathname2url('Upload.xml')
>>> mime_type = mime.guess_type(url)
>>> print mime_type
('application/xml', None)

Please refer Old Post

Update - In python 3+ version, it's more convenient now:

import mimetypes
print(mimetypes.guess_type("sample.html"))

I resolved a similar issue by simply restarting Visual Studio with admin rights.

The problem was because it couldn't open one project related to Sharepoint without elevated access.

It turns out that, yes, the problem is not simple, but the solution is.

First I had to create a shell script to wrap the "source" command. That said I used the "." instead, because I've read that it's better to use it than source for Bash scripts.

#!/bin/bash
. /path/to/env/bin/activate

Then from my Python script I can simply do this:

import os
os.system('/bin/bash --rcfile /path/to/myscript.sh')

The whole trick lies within the --rcfile argument.

When the Python interpreter exits it leaves the current shell in the activated environment.

Win!

I've just had this issue without changing PATH.

My PC is Win7, 64-bit system, If you are also using 64-bit system, you may want to try:

1. uninstall your current Firefox.
2. install new Firefox under "C:\Program Files (x86)\Mozilla Firefox\" path.

It must be under "Program Files (x86)" NOT "Program Files"

Hope it can help.

Use this filter mask on email input: emailMask: /[\w.\-@'"!#$%&'*+/=?^_{|}~]/i`

If you're looking to simply reduce or increase the width of Bootstrap's input elements to your liking, I would use max-width in the CSS.

Here is a very simple example I created:

    <form style="max-width:500px">

    <div class="form-group"> 
    <input type="text" class="form-control" id="name" placeholder="Name">
    </div>

    <div class="form-group">
    <input type="email" class="form-control" id="email" placeholder="Email Address">
    </div>

    <div class="form-group">
    <textarea class="form-control" rows="5" placeholder="Message"></textarea>
    </div>   

    <button type="submit" class="btn btn-primary">Submit</button>
    </form>

I've set the whole form's maximum width to 500px. This way you won't need to use any of Bootstrap's grid system and it will also keep the form responsive.

most simple answer

<a onclick="window.open(this.href,'_blank');return false;" href="http://www.foracure.org.au">Some Other Site</a>

it will work

Nice explanation and example above. I found this (JSON.stringify() array bizarreness with Prototype.js) to complete the answer. Some sites implements its own toJSON with JSONFilters, so delete it.

if(window.Prototype) {
    delete Object.prototype.toJSON;
    delete Array.prototype.toJSON;
    delete Hash.prototype.toJSON;
    delete String.prototype.toJSON;
}

it works fine and the output of the test:

console.log(json);

Result:

"{"a":"test","b":["item","item2","item3"]}"

I use the following, it also tests the extension which means it can be used for testing if the path supplied is a file but a file that doesn't exist.

private static bool isDirectory(string path)
{
    bool result = true;
    System.IO.FileInfo fileTest = new System.IO.FileInfo(path);
    if (fileTest.Exists == true)
    {
        result = false;
    }
    else
    {
        if (fileTest.Extension != "")
        {
            result = false;
        }
    }
    return result;
}

I've never come across point 2? Can you explain why you think this affects deployment in any way. If anything maven allows you to structure your projects in a modularised way that actually allows hot fixes for bugs in a particular tier, and allows independent development of an API from the remainder of the project for example.

It is possible that you are trying to cram everything into a single module, in which case the problem isn't really maven at all, but the way you are using it.

I created a game framework sometime ago to work on Android and Desktop, the desktop part that handle sound maybe can be used as inspiration to what you need.

There is a convenient Unipath module.

>>> from unipath import Path 
>>>  
>>> Path('/var/log').exists()
True
>>> Path('/var/log').isdir()
True

Other related things you might need:

>>> Path('/var/log/system.log').parent
Path('/var/log')
>>> Path('/var/log/system.log').ancestor(2)
Path('/var')
>>> Path('/var/log/system.log').listdir()
[Path('/var/foo'), Path('/var/bar')]
>>> (Path('/var/log') + '/system.log').isfile()
True

You can install it using pip:

$ pip3 install unipath

It's similar to the built-in pathlib. The difference is that it treats every path as a string (Path is a subclass of the str), so if some function expects a string, you can easily pass it a Path object without a need to convert it to a string.

For example, this works great with Django and settings.py:

# settings.py
BASE_DIR = Path(__file__).ancestor(2)
STATIC_ROOT = BASE_DIR + '/tmp/static'

You can call the method newLine() provided by java, to insert the new line in to a file.

For more refernce -http://download.oracle.com/javase/1.4.2/docs/api/java/io/BufferedWriter.html#newLine()

select * from your_table where MONTH(mont_year) = MONTH(NOW()) and YEAR(mont_year) = YEAR(NOW());

Note: (month_year) means your column that contain date format. I think that will solve your problem. Let me know if that query doesn't works.

I think because your are using play-service 8.4.0

It required

classpath 'com.android.tools.build:gradle:2.0.0-alpha5'
classpath 'com.google.gms:google-services:2.0.0-alpha5'

Add the following CSS;

.modal .modal-dialog .modal-content{  background-color: #d4c484; }

<div class="modal fade">
<div class="modal-dialog" role="document">
<div class="modal-content">
...
...

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

Still using indirect. Say your A1 cell is your variable that will contain the name of the referenced sheet (Jan). If you go by:

=INDIRECT(CONCATENATE("'",A1," Item'", "!J3"))

Then you will have the 'Jan Item'!J3 value.

XML is not a format for storing images, neither binary data. I think it all depends on how you want to use those images. If you are in a web application and would want to read them from there and display them, I would store the URLs. If you need to send them to another web endpoint, I would serialize them, rather than persisting manually in XML. Please explain what is the scenario.

You can also try this for match string.

DECLARE @temp1 VARCHAR(1000)
    SET @temp1 = '<li>Error in connecting server.</li>'
DECLARE @temp2 VARCHAR(1000)
    SET @temp2 = '<li>Error in connecting server. connection timeout.</li>'

IF @temp1 like '%Error in connecting server.%' OR @temp1 like '%Error in connecting server. connection timeout.%'
  SELECT 'yes'
ELSE
  SELECT 'no'

ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.

Try adding a .eslintrc file to your project. Inside it:

{
    "parserOptions": {
        "ecmaVersion": 2017
    },

    "env": {
        "es6": true
    }
}

Hopefully this helps.

EDIT: I also found this example .eslintrc which might help.

ClassLoader.getResourceAsStream and Class.getResourceAsStream are definitely the way to go for loading the resource data. However, I don't believe there's any way of "listing" the contents of an element of the classpath.

In some cases this may be simply impossible - for instance, a ClassLoader could generate data on the fly, based on what resource name it's asked for. If you look at the ClassLoader API (which is basically what the classpath mechanism works through) you'll see there isn't anything to do what you want.

If you know you've actually got a jar file, you could load that with ZipInputStream to find out what's available. It will mean you'll have different code for directories and jar files though.

One alternative, if the files are created separately first, is to include a sort of manifest file containing the list of available resources. Bundle that in the jar file or include it in the file system as a file, and load it before offering the user a choice of resources.

In addition to the above, you can do this (where "YourListObjectName" is the name of your table):

Dim LO As ListObject
Set LO = ActiveSheet.ListObjects("YourListObjectName")

But I think that only works if you want to reference a list object that's on the active sheet.

I found your question because I wanted to refer to a list object (a table) on one worksheet that a pivot table on a different worksheet refers to. Since list objects are part of the Worksheets collection, you have to know the name of the worksheet that list object is on in order to refer to it. So to get the name of the worksheet that the list object is on, I got the name of the pivot table's source list object (again, a table) and looped through the worksheets and their list objects until I found the worksheet that contained the list object I was looking for.

Public Sub GetListObjectWorksheet()
' Get the name of the worksheet that contains the data
' that is the pivot table's source data.

    Dim WB As Workbook
    Set WB = ActiveWorkbook

    ' Create a PivotTable object and set it to be
    ' the pivot table in the active cell:
    Dim PT As PivotTable
    Set PT = ActiveCell.PivotTable

    Dim LO As ListObject
    Dim LOWS As Worksheet

    ' Loop through the worksheets and each worksheet's list objects
    ' to find the name of the worksheet that contains the list object
    ' that the pivot table uses as its source data:
    Dim WS As Worksheet
    For Each WS In WB.Worksheets
        ' Loop through the ListObjects in each workshet:
        For Each LO In WS.ListObjects
            ' If the ListObject's name is the name of the pivot table's soure data,
            ' set the LOWS to be the worksheet that contains the list object:
            If LO.Name = PT.SourceData Then
                Set LOWS = WB.Worksheets(LO.Parent.Name)
            End If
        Next LO
    Next WS

    Debug.Print LOWS.Name

End Sub

Maybe someone knows a more direct way.

htmlStr is string then You need to Date and Time variables to string

while (reader.Read())
                {
                    DateTime Date = reader.GetDateTime(0);
                    DateTime Time = reader.GetDateTime(1);
                    htmlStr += "<tr><td>" + Date.ToString() + "</td><td>"  + 
                    Time.ToString() + "</td></tr>";                  
                }

in handlebars first register a function like below

Handlebars.registerHelper('ifEquals', function(arg1, arg2, options) {
    return (arg1 == arg2) ? options.fn(this) : options.inverse(this);
});

you can register more than one function . to add another function just add like below

Handlebars.registerHelper('calculate', function(operand1, operator, operand2) {
    let result;
    switch (operator) {
        case '+':
            result = operand1 + operand2;            
            break;
        case '-':
            result = operand1 - operand2;            
            break;
        case '*':
            result = operand1 * operand2;            
            break;
        case '/':
            result = operand1 / operand2;            
            break;
    }

    return Number(result);
});

and in HTML page just include the conditions like

    {{#ifEquals day "mon"}}
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
      //html code goes here
    </html>
   {{else ifEquals day "sun"}}
    <html>
     //html code goes here
    </html>
   {{else}}
     //html code goes here
   {{/ifEquals}}

Method 1

public static void increaseFontSizeForPath(Spannable spannable, String path, float increaseTime) {
    int startIndexOfPath = spannable.toString().indexOf(path);
    spannable.setSpan(new RelativeSizeSpan(increaseTime), startIndexOfPath,
            startIndexOfPath + path.length(), 0);
}

using

Utils.increaseFontSizeForPath(spannable, "big", 3); // make "big" text bigger 3 time than normal text

Method 2

public static void setFontSizeForPath(Spannable spannable, String path, int fontSizeInPixel) {
    int startIndexOfPath = spannable.toString().indexOf(path);
    spannable.setSpan(new AbsoluteSizeSpan(fontSizeInPixel), startIndexOfPath,
            startIndexOfPath + path.length(), 0);
}

using

Utils.setFontSizeForPath(spannable, "big", (int) textView.getTextSize() + 20); // make "big" text bigger 20px than normal text

You can use hash.keys.include?(key)

irb(main):001:0> hash = {"pot" => 1, "tot" => 2, "not" => 3}
=> {"pot"=>1, "tot"=>2, "not"=>3}
irb(main):002:0> key = "not"
=> "not"
irb(main):003:0> hash.keys.include?(key)
=> true

Why not try fadeOut?

$(document).ready(function() {_x000D_
  $('#plsme').fadeOut(5000); // 5 seconds x 1000 milisec = 5000 milisec_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<div id='plsme'>Loading... Please Wait</div>

fadeOut (Javascript Pure):

How to make fadeOut effect with pure JavaScript

you can check installed c# compilers and the printed version of the .net:

@echo off

for /r "%SystemRoot%\Microsoft.NET\Framework\" %%# in ("*csc.exe") do (
    set "l="
    for /f "skip=1 tokens=2 delims=k" %%$ in ('"%%# #"') do (
        if not defined l (
            echo Installed: %%$
            set l=%%$
        )
    )
)

echo latest installed .NET %l%

the csc.exe does not have a -version switch but it prints the .net version in its logo. You can also try with msbuild.exe but .net framework 1.* does not have msbuild.

After typing "prop" + Tab + Tab as suggested by Amra, you can immediately type the property's type (which will replace the default int), type another tab and type the property name (which will replace the default MyProperty). Finish by pressing Enter.

Java Closures are going to be a part of J2SE 8 and is set to be released by the end of 2012.

Java 8's closures support include the concept of Lambda Expressions, Method Reference, Constructor Reference and the Default Methods.

For more information and working examples for this please visit: http://amitrp.blogspot.in/2012/08/at-first-sight-with-closures-in-java.html

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

I had a similar need and end up using componentDidMount(), that one is called long after component class constructor (where you can initialize state from props - as an exmple using redux )

Inside componentDidMount you can then invoke your handleChange method for some UI animation or perform any kind of component properties updates required.

As an example I had an issue updating an input checkbox type programatically, that's why I end up using this code, as onChange handler was not firing at component load:

   componentDidMount() {

    // Update checked 
    const checkbox = document.querySelector('[type="checkbox"]');

    if (checkbox) 
      checkbox.checked = this.state.isChecked;
  }

State was first updated in component class constructor and then utilized to update some input component behavior

You can use the title attribute.

<img height="90" width="90"
src="http://www.google.com/intl/en_ALL/images/logos/images_logo_lg.gif"
alt="Google Images" title="Google Images" />

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

Lightweight example (with support for onSuccess and onTimeout). You need to pass callback name within URL if you need it.

var $jsonp = (function(){
  var that = {};

  that.send = function(src, options) {
    var callback_name = options.callbackName || 'callback',
      on_success = options.onSuccess || function(){},
      on_timeout = options.onTimeout || function(){},
      timeout = options.timeout || 10; // sec

    var timeout_trigger = window.setTimeout(function(){
      window[callback_name] = function(){};
      on_timeout();
    }, timeout * 1000);

    window[callback_name] = function(data){
      window.clearTimeout(timeout_trigger);
      on_success(data);
    }

    var script = document.createElement('script');
    script.type = 'text/javascript';
    script.async = true;
    script.src = src;

    document.getElementsByTagName('head')[0].appendChild(script);
  }

  return that;
})();

Sample usage:

$jsonp.send('some_url?callback=handleStuff', {
    callbackName: 'handleStuff',
    onSuccess: function(json){
        console.log('success!', json);
    },
    onTimeout: function(){
        console.log('timeout!');
    },
    timeout: 5
});

As suggested by Nineroad Installing WindowBuilder as the default editor for files with a *.java extention fixed this issue for me.

Add http://archive.eclipse.org/windowbuilder/WB/release/R201309271200/4.3 to the "Work with" path, select all components suggested, and install WindowBuilder.

Once complete, Eclipse will request restart. Once restarted, within Eclipse navigate to Window > Preferences. In The Preferences dialogue-box navigate to General > Editor > File Associations. Under "File Associations" list, be sure to select *.java file types. The bottom window (labeled "Associated Editors") should have WindowBuilder as an option. Select WindowBuilder and click "Default" to the right, to set WindowBuilder as your default *.java file editor.

This fixed the SWT error for me.

How about making a custom class containing an array, and use the array of your custom class.

rails s -e production

This will run the server with RAILS_ENV = 'production'.

Apart from this you have to set the assets path in production.rb

config.serve_static_assets = true

Without this your assets will not be loaded.

#!/usr/bin/python
# -*- coding: utf-8 -*-
# Works on python 3 and python 2.
# when server knows where the request is coming from.

import sys

if sys.version_info[0] == 3:
    from urllib.request import urlopen
else:
    from urllib import urlopen
with urlopen('https://www.facebook.com/') as \
    url:
    data = url.read()

print data

# When the server does not know where the request is coming from.
# Works on python 3.

import urllib.request

user_agent = \

url = 'https://www.facebook.com/'
headers = {'User-Agent': user_agent}

request = urllib.request.Request(url, None, headers)
response = urllib.request.urlopen(request)
data = response.read()
print data

Just to chime in, Emanuel had the answer that I (and probably many others) are looking for. If you have 3d scattered data in 3 separate arrays, pandas is an incredible help and works much better than the other options. To elaborate, suppose your x,y,z are some arbitrary variables. In my case these were c,gamma, and errors because I was testing a support vector machine. There are many potential choices to plot the data:

• scatter3D(cParams, gammas, avg_errors_array) - this works but is overly simplistic
• plot_wireframe(cParams, gammas, avg_errors_array) - this works, but will look ugly if your data isn't sorted nicely, as is potentially the case with massive chunks of real scientific data
• ax.plot3D(cParams, gammas, avg_errors_array) - similar to wireframe

Wireframe plot of the data

3d scatter of the data

The code looks like this:

    fig = plt.figure()
    ax = fig.gca(projection='3d')
    ax.set_xlabel('c parameter')
    ax.set_ylabel('gamma parameter')
    ax.set_zlabel('Error rate')
    #ax.plot_wireframe(cParams, gammas, avg_errors_array)
    #ax.plot3D(cParams, gammas, avg_errors_array)
    #ax.scatter3D(cParams, gammas, avg_errors_array, zdir='z',cmap='viridis')

    df = pd.DataFrame({'x': cParams, 'y': gammas, 'z': avg_errors_array})
    surf = ax.plot_trisurf(df.x, df.y, df.z, cmap=cm.jet, linewidth=0.1)
    fig.colorbar(surf, shrink=0.5, aspect=5)    
    plt.savefig('./plots/avgErrs_vs_C_andgamma_type_%s.png'%(k))
    plt.show()

Here is the final output:

As Dillon Kearns suggested, setting focusable to false works fine. But if your goal is to cancel the keyboard when EditText is clicked, you might want to use:

mEditText.setInputType(0);

In my fairly complex scenario the accepted answer for how to do this in Chrome doesn't work for me. You may want to try the Firefox debugger instead (part of the Firefox developer tools), which shows all of the 'Sources', including those that are part of an iFrame

You could use JavaScript and XMLHTTPRequest (AJAX) to perform a POST without using a form. Check this link out. Keep in mind that you will need JavaScript enabled in your browser though.

DATEPART function doesn't work on MySQL 5.6, instead use MONTH('2018-01-01')

Have a look at the documentation. You made the following mistakes. Firstly, ps.executeQuery() doesn't have any parameters. Instead you passed the SQL query into it.

Secondly, regarding the prepared statement, you have to use the ? symbol if want to pass any parameters. And later bind it using

setXXX(index, value) 

Here xxx stands for the data type.

I used this bubble sort because I wasnt able to order them by the .value in the options array and it was a number. This way I got them properly ordered. I hope it's useful to you too.

function sortSelect(selElem) {
  for (var i=0; i<(selElem.options.length-1); i++)
      for (var j=i+1; j<selElem.options.length; j++)
          if (parseInt(selElem.options[j].value) < parseInt(selElem.options[i].value)) {
              var dummy = new Option(selElem.options[i].text, selElem.options[i].value);
              selElem.options[i] = new Option(selElem.options[j].text, selElem.options[j].value);
              selElem.options[j] = dummy;
          }
}

if you are allowed to do it globally then you can set the session time out in

TOMCAT_HOME/conf/web.xml as below

 <!-- ==================== Default Session Configuration ================= -->
  <!-- You can set the default session timeout (in minutes) for all newly   -->
  <!-- created sessions by modifying the value below.                       -->


<session-config>
        <session-timeout>60</session-timeout>
</session-config>

The ssh2 functions aren't very good. Hard to use and harder yet to install, using them will guarantee that your code has zero portability. My recommendation would be to use phpseclib, a pure PHP SFTP implementation.

I got this when pulling into an Rstudio project. I realised I forgot to do:

sudo rstudio

on program startup. In fact as there's another bug I've got, I need to actually do:

sudo rstudio --no-sandbox

much easier:

<EditText
    android:inputType="text"
    android:digits="0,1,2,3,4,5,6,7,8,9,*,qwertzuiopasdfghjklyxcvbnm" />

This error can also be the ultimate sign of a dumb mistake (like when I - I mean, cough, like when a friend of mine who showed me their code once) where they try to execute code outside of a method like trying to do this:

SQLiteDatabase db = openOrCreateDatabase("DB", MODE_PRIVATE, null); //trying to perform function where you can only set up objects, primitives, etc

@Override
public void onCreate(Bundle savedInstanceState) {
....
}

rather than this:

SQLiteDatabase db;

@Override
public void onCreate(Bundle savedInstanceState) {
db = openOrCreateDatabase("DB", MODE_PRIVATE, null);
....
}

check this code for the problem:

$sql = "SELECT * FROM tablename WHERE condition";

$res = mysql_query($sql);

while ($row = mysql_fetch_assoc($res)) {

    foreach($row as $key => $field) {  

        echo "<br>";

        if(empty($row[$key])){

            echo $key." : empty field :"."<br>"; 

        }else{

        echo $key." =" . $field."<br>";     

        }
    }
}

It depends on what encoding you use. If you want to convert utf-8 encoded hex to string, use this:

function fromHex(hex,str){
  try{
    str = decodeURIComponent(hex.replace(/(..)/g,'%$1'))
  }
  catch(e){
    str = hex
    console.log('invalid hex input: ' + hex)
  }
  return str
}

For the other direction use this:

function toHex(str,hex){
  try{
    hex = unescape(encodeURIComponent(str))
    .split('').map(function(v){
      return v.charCodeAt(0).toString(16)
    }).join('')
  }
  catch(e){
    hex = str
    console.log('invalid text input: ' + str)
  }
  return hex
}

quick answer is this:

sh "ls -l > commandResult"
result = readFile('commandResult').trim()

I think there exist a feature request to be able to get the result of sh step, but as far as I know, currently there is no other option.

EDIT: JENKINS-26133

EDIT2: Not quite sure since what version, but sh/bat steps now can return the std output, simply:

def output = sh returnStdout: true, script: 'ls -l'

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
    sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}
label1.Text = sum.ToString();

To use it in phtml apply :

echo $this->getSkinUrl('your_image_folder_under_skin/image_name.png');

To use skin path in cms page :

<img style="width: 715px; height: 266px;" src="{{skin url=images/banner1.jpg}}" alt="title" />

This part====> {{skin url=images/banner1.jpg}}

I hope this will help you.

What is wrong with using string.Length?

// len will be 5
int len = "Hello".Length;

Please set the request Content Type before you read the response stream;

 request.ContentType = "text/xml";

Functions cannot be used to modify base table information, use a stored procedure.

My solution,

load the app using

NODE_ENV=production node app.js

Then setup config.js as a function rather than an object

module.exports = function(){
    switch(process.env.NODE_ENV){
        case 'development':
            return {dev setting};

        case 'production':
            return {prod settings};

        default:
            return {error or other settings};
    }
};

Then as per Jans solution load the file and create a new instance which we could pass in a value if needed, in this case process.env.NODE_ENV is global so not needed.

var Config = require('./conf'),
    conf = new Config();

Then we can access the config object properties exactly as before

conf.twitter.consumerKey

Three things to know:

1. The percent sign is used in batch files to represent command line parameters: %1, %2, ...

2. Two percent signs with any characters in between them are interpreted as a variable:

   echo %myvar%

3. Two percent signs without anything in between (in a batch file) are treated like a single percent sign in a command (not a batch file): %%f

Why's that?

For example, if we execute your (simplified) command line

FOR /f %f in ('dir /b .') DO somecommand %f

in a batch file, rule 2 would try to interpret

%f in ('dir /b .') DO somecommand %

as a variable. In order to prevent that, you have to apply rule 3 and escape the % with an second %:

FOR /f %%f in ('dir /b .') DO somecommand %%f

Ctrl-K, Ctrl-D

Will just prettify the entire document. Saves a lot of messing about, compared to delphi.

Make sure to remove all indents by first selecting everything with Ctrl+A then press Shift+Tab repeatedly until everything is aligned to the left. After you do that Ctrl+K, Ctrl+D will work the way you want them to.

You could also do the same but only to a selection of code by highlighting the block of code you want to realign, aligning it to the left side (Shift+Tab) and then after making sure you've selected the code you want to realign press Ctrl+K, Ctrl+F or just right click the highlighted code and select "Format Selection".

The below solution is more straight-forward. All you have to do is define one simple function that can "CREATE" the object from the two given items. Then simply apply this function to TWO arrays having elements for which you want to create object and save in resultArray.

var arr1 = ['01','02','03'];
var arr2 = ['item-1','item-2','item-3'];
resultArray = [];
    for (var j=0; j<arr1.length; j++) {
        resultArray[j] = new makeArray(arr1[j], arr2[j]);
    }
function makeArray(first,second) {
    this.first = first;
    this.second = second;
}

I have just finished adding Google Maps to my company's CMS offering. My code allows for more than one map in a page.

Notes:

• I use jQuery
• I put the address in the content and then parse it out to dynamically generate the map
• I include a Marker and an InfoWindow in my map

I use

select /*+ parallel(a) */  count(1) from table_name a;

I found some of the solutions here to be slow and/or confusing (and some of them don't handle ties correctly) so I wrote my own data.table based function auc_roc() in my R package mltools.

library(data.table)
library(mltools)

preds <- c(.1, .3, .3, .9)
actuals <- c(0, 0, 1, 1)

auc_roc(preds, actuals)  # 0.875

auc_roc(preds, actuals, returnDT=TRUE)
   Pred CountFalse CountTrue CumulativeFPR CumulativeTPR AdditionalArea CumulativeArea

For Python 3.x, use input(). For Python 2.x, use raw_input(). Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!").

Rationale for the / POSIX PATH rule

The rule was mentioned at: Why do you need ./ (dot-slash) before executable or script name to run it in bash? but I would like to explain why I think that is a good design in more detail.

First, an explicit full version of the rule is:

• if the path contains / (e.g. ./someprog, /bin/someprog, ./bin/someprog): CWD is used and PATH isn't
• if the path does not contain / (e.g. someprog): PATH is used and CWD isn't

Now, suppose that running:

someprog

would search:

• relative to CWD first
• relative to PATH after

Then, if you wanted to run /bin/someprog from your distro, and you did:

someprog

it would sometimes work, but others it would fail, because you might be in a directory that contains another unrelated someprog program.

Therefore, you would soon learn that this is not reliable, and you would end up always using absolute paths when you want to use PATH, therefore defeating the purpose of PATH.

This is also why having relative paths in your PATH is a really bad idea. I'm looking at you, node_modules/bin.

Conversely, suppose that running:

./someprog

Would search:

• relative to PATH first
• relative to CWD after

Then, if you just downloaded a script someprog from a git repository and wanted to run it from CWD, you would never be sure that this is the actual program that would run, because maybe your distro has a:

/bin/someprog

which is in you PATH from some package you installed after drinking too much after Christmas last year.

Therefore, once again, you would be forced to always run local scripts relative to CWD with full paths to know what you are running:

"$(pwd)/someprog"

which would be extremely annoying as well.

Another rule that you might be tempted to come up with would be:

relative paths use only PATH, absolute paths only CWD

but once again this forces users to always use absolute paths for non-PATH scripts with "$(pwd)/someprog".

The / path search rule offers a simple to remember solution to the about problem:

• slash: don't use PATH
• no slash: only use PATH

which makes it super easy to always know what you are running, by relying on the fact that files in the current directory can be expressed either as ./somefile or somefile, and so it gives special meaning to one of them.

Sometimes, is slightly annoying that you cannot search for some/prog relative to PATH, but I don't see a saner solution to this.

ElementTree is not too smart about namespaces. You need to give the .find(), findall() and iterfind() methods an explicit namespace dictionary. This is not documented very well:

namespaces = {'owl': 'http://www.w3.org/2002/07/owl#'} # add more as needed

root.findall('owl:Class', namespaces)

Prefixes are only looked up in the namespaces parameter you pass in. This means you can use any namespace prefix you like; the API splits off the owl: part, looks up the corresponding namespace URL in the namespaces dictionary, then changes the search to look for the XPath expression {http://www.w3.org/2002/07/owl}Class instead. You can use the same syntax yourself too of course:

root.findall('{http://www.w3.org/2002/07/owl#}Class')

If you can switch to the lxml library things are better; that library supports the same ElementTree API, but collects namespaces for you in a .nsmap attribute on elements.

• View.GONE->The View is not visible and it will not occupy any space in layout

Operator + is a unary operator which converts value to number. Below I prepared a table with corresponding results of using this operator for different values.

+-----------------------------+-----------+
| Value                       | + (Value) |
+-----------------------------+-----------+
| 1                           | 1         |
| '-1'                        | -1        |
| '3.14'                      | 3.14      |
| '3'                         | 3         |
| '0xAA'                      | 170       |
| true                        | 1         |
| false                       | 0         |
| null                        | 0         |
| 'Infinity'                  | Infinity  |
| 'infinity'                  | NaN       |
| '10a'                       | NaN       |
| undefined                   | Nan       |
| ['Apple']                   | Nan       |
| function(val){ return val } | NaN       |
+-----------------------------+-----------+

Operator + returns value for objects which have implemented method valueOf.

let something = {
    valueOf: function () {
        return 25;
    }
};

console.log(+something);

Try this

    Handler mHandler = new Handler(Looper.getMainLooper());
                        mHandler.post(new Runnable() {
                            @Override
                            public void run() {
 //your code here that talks with the UI level widgets/ try to access the UI 
//elements from this block because this piece of snippet will run in the UI/MainThread.                                     
                            }
                        });

Regarding the single quote, see the code below used to replace the string let's with let us:

command:

echo "hello, let's go"|sed 's/let'"'"'s/let us/g'

result:

hello, let us go

This issue is due to ArrayList variable not being instantiated. Need to declare "recordings" variable like following, that should solve the issue;

ArrayList<String> recordings = new ArrayList<String>();

this calls default constructor and assigns empty string to the recordings variable so that it is not null anymore.

Heres what I do for Bootstrap 3/4

Use container-fluid instead of container.

Add this to my CSS

@media (min-width: 1400px) {
    .container-fluid{
        max-width: 1400px;
    }   
}

This removes margins below 1400px width screen

I did it in my project:

Global Events in application.js:

$(document).bind("ajaxSend", function(){
   $("#loading").show();
 }).bind("ajaxComplete", function(){
   $("#loading").hide();
 });

"loading" is the element to show and hide!

I highly suggest you to use an array instead of an object if you're doing react itteration, this is a syntax I use it ofen.

const rooms = this.state.array.map((e, i) =>(<div key={i}>{e}</div>))

To use the element, just place {rooms} in your jsx.

Where e=elements of the arrays and i=index of the element. Read more here. If your looking for itteration, this is the way to do it.

Alternatively, right after you commit to the wrong branch, perform these steps:

1. git log
2. git diff {previous to last commit} {latest commit} > your_changes.patch
3. git reset --hard origin/{your current branch}
4. git checkout -b {new branch}
5. git apply your_changes.patch

I can imagine that there is a simpler approach for steps one and two.

A good way to findout what header file you are missing:

 man <section> <function call>

To find out the section use:

apropos <function call>

Example:

 man 3 memset
 man 2 send

SyntaxHighlighter is a fully functional self-contained code syntax highlighter developed in JavaScript. To get an idea of what SyntaxHighlighter is capable of, have a look at the demo page.

>>> n, m = 6, 3
>>> k = n - m+1
>>> print ('{}\n'*(k)).format(*[range(i, i+m) for i in xrange(k)])
[0, 1, 2]
[1, 2, 3]
[2, 3, 4]
[3, 4, 5]

private void btnEnter_Click(object sender, EventArgs e)
{
    maskedTextBox1.Mask = "00/00/0000";
    maskedTextBox1.ValidatingType = typeof(System.DateTime);
    //if (!IsValidDOB(maskedTextBox1.Text)) 
    if (!ValidateBirthday(maskedTextBox1.Text))
        MessageBox.Show(" Not Valid");
    else
        MessageBox.Show("Valid");
}
// check date format dd/mm/yyyy. but not if year < 1 or > 2013.
public static bool IsValidDOB(string dob)
{ 
    DateTime temp;
    if (DateTime.TryParse(dob, out temp))
        return (true);
    else 
        return (false);

    DateTime Temp;
    if (DateTime.TryParse(date, out Temp) == true &&
        Temp.Year > 1900 &&
       // Temp.Hour == 0 && Temp.Minute == 0 &&
        //Temp.Second == 0 && Temp.Millisecond == 0 &&
        Temp > DateTime.MinValue)

Look into nginx config file to be sure. This command greps for whatever is configured on your Machine:

cat /etc/nginx/sites-enabled/default |grep "root"

on my machine it was :root /usr/share/nginx/www;

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

There are multiple number groups and some particular numbers that will never be allocated:

• Numbers with all zeros in any digit group (000-xx-####, ###-00-####, ###-xx-0000).
• Numbers with an area group (first three digits) of 666 or any of 900-999.
• Numbers that have been misused in any way, such as the well known 078-05-1120.

Consider using one of these (the obviously invalid 000-00-0000 would be a good one IMO).

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

Expanding on this method, applied to finding the mode of the data where you may need the index of the actual array to see how far away the value is from the center of the distribution.

(_, idx, counts) = np.unique(a, return_index=True, return_counts=True)
index = idx[np.argmax(counts)]
mode = a[index]

Remember to discard the mode when len(np.argmax(counts)) > 1

bash and sh are two different shells. Basically bash is sh, with more features and better syntax. Most commands work the same, but they are different.Bash (bash) is one of many available (yet the most commonly used) Unix shells. Bash stands for "Bourne Again SHell",and is a replacement/improvement of the original Bourne shell (sh).

Shell scripting is scripting in any shell, whereas Bash scripting is scripting specifically for Bash. In practice, however, "shell script" and "bash script" are often used interchangeably, unless the shell in question is not Bash.

Having said that, you should realize /bin/sh on most systems will be a symbolic link and will not invoke sh. In Ubuntu /bin/sh used to link to bash, typical behavior on Linux distributions, but now has changed to linking to another shell called dash. I would use bash, as that is pretty much the standard (or at least most common, from my experience). In fact, problems arise when a bash script will use #!/bin/sh because the script-maker assumes the link is to bash when it doesn't have to be.

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

In scikit version 0.22, you can do it like this

from sklearn.metrics import multilabel_confusion_matrix

y_true = ["cat", "ant", "cat", "cat", "ant", "bird"]
y_pred = ["ant", "ant", "cat", "cat", "ant", "cat"]

mcm = multilabel_confusion_matrix(y_true, y_pred,labels=["ant", "bird", "cat"])

tn = mcm[:, 0, 0]
tp = mcm[:, 1, 1]
fn = mcm[:, 1, 0]
fp = mcm[:, 0, 1]

You use the available API of JTable and do not try to mess with the colors.

Some selection methods are available directly on the JTable (like the setRowSelectionInterval). If you want to have access to all selection-related logic, the selection model is the place to start looking

In case you don't have the indices of the elements you want to remove, you can use the function in1d provided by numpy.

The function returns True if the element of a 1-D array is also present in a second array. To delete the elements, you just have to negate the values returned by this function.

Notice that this method keeps the order from the original array.

In [1]: import numpy as np

        a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9])
        rm = np.array([3, 4, 7])
        # np.in1d return true if the element of `a` is in `rm`
        idx = np.in1d(a, rm)
        idx

Out[1]: array([False, False,  True,  True, False, False,  True, False, False])

In [2]: # Since we want the opposite of what `in1d` gives us, 
        # you just have to negate the returned value
        a[~idx]

Out[2]: array([1, 2, 5, 6, 8, 9])

Here's how extend/assign works: For each property in source, copy its value as-is to destination. if property values themselves are objects, there is no recursive traversal of their properties. Entire object would be taken from source and set in to destination.

Here's how merge works: For each property in source, check if that property is object itself. If it is then go down recursively and try to map child object properties from source to destination. So essentially we merge object hierarchy from source to destination. While for extend/assign, it's simple one level copy of properties from source to destination.
