Slide animation can be applied to activity transitions by calling overridePendingTransition and passing animation resources for enter and exit activities.

Slide animations can be slid right, slide left, slide up and slide down.

Slide up

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/linear_interpolator">
    <scale
        android:duration="800"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:toXScale="1.0"
        android:toYScale="0.0" />
</set>

Slide down

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/linear_interpolator">
    <scale
        android:duration="800"
        android:fromXScale="1.0"
        android:fromYScale="0.0"
        android:toXScale="1.0"
        android:toYScale="1.0" />
</set>

overridePendingTransition(R.anim.slide_down, R.anim.slide_up);

See activity transition animation examples for more activity transition examples.

You can do two things to add animations, first you can let android animate layout changes for you. That way every time you change something in the layout like changing view visibility or view positions android will automatically create fade/transition animations. To use that set

android:animateLayoutChanges="true"

on the root node in your layout.

Your second option would be to manually add animations. For this I suggest you use the new animation API introduced in Android 3.0 (Honeycomb). I can give you a few examples:

This fades out a View:

view.animate().alpha(0.0f);

This fades it back in:

view.animate().alpha(1.0f);

This moves a View down by its height:

view.animate().translationY(view.getHeight());

This returns the View to its starting position after it has been moved somewhere else:

view.animate().translationY(0);

You can also use setDuration() to set the duration of the animation. For example this fades out a View over a period of 2 seconds:

view.animate().alpha(0.0f).setDuration(2000);

And you can combine as many animations as you like, for example this fades out a View and moves it down at the same time over a period of 0.3 seconds:

view.animate()
        .translationY(view.getHeight())
        .alpha(0.0f)
        .setDuration(300);

And you can also assign a listener to the animation and react to all kinds of events. Like when the animation starts, when it ends or repeats etc. By using the abstract class AnimatorListenerAdapter you don't have to implement all callbacks of AnimatorListener at once but only those you need. This makes the code more readable. For example the following code fades out a View moves it down by its height over a period of 0.3 seconds (300 milliseconds) and when the animation is done its visibility is set to View.GONE.

view.animate()
        .translationY(view.getHeight())
        .alpha(0.0f)
        .setDuration(300)
        .setListener(new AnimatorListenerAdapter() {
            @Override
            public void onAnimationEnd(Animator animation) {
                super.onAnimationEnd(animation);
                view.setVisibility(View.GONE);
            }
        });

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

You can try this way -

ObjectAnimator.ofFloat(view, "translationX", 100f).apply {
    duration = 2000
    start()
}

Note - view is your view where you want animation.

In DialogFragment, custom animation is called onCreateDialog. 'DialogAnimation' is custom animation style in previous answer.

public Dialog onCreateDialog(Bundle savedInstanceState) 
{
    final Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
    return dialog;
}

imgDics = (ImageView) v.findViewById(R.id.img_player_tab2_dics);
    imgDics.setOnClickListener(onPlayer2Click);
    anim = new RotateAnimation(0f, 360f,
            Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
                            0.5f);
    anim.setInterpolator(new LinearInterpolator());
    anim.setRepeatCount(Animation.INFINITE);
    anim.setDuration(4000);

    // Start animating the image
    imgDics.startAnimation(anim);

Try this :

Create anim folder inside your res folder and copy this four files :

slide_in_bottom.xml :

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="100%p"
android:duration="@android:integer/config_longAnimTime"/>  

slide_out_bottom.xml :

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="0" 
android:duration="@android:integer/config_longAnimTime" /> 

slide_in_top.xml :

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:toYDelta="0%p"
android:duration="@android:integer/config_longAnimTime" />

slide_out_top.xml :

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:toYDelta="100%p"
android:duration="@android:integer/config_longAnimTime" />

When you click on image view call:

overridePendingTransition(R.anim.slide_in_bottom, R.anim.slide_out_bottom);

When you click on original place call:

overridePendingTransition(R.anim.slide_in_top, R.anim.slide_out_top);

Hope this helps.

To get MaxX and MaxY, read on.

For Android device screen coordinates, below concept will work.

Display mdisp = getWindowManager().getDefaultDisplay();
Point mdispSize = new Point();
mdisp.getSize(mdispSize);
int maxX = mdispSize.x; 
int maxY = mdispSize.y;

EDIT:- ** **for devices supporting android api level older than 13. Can use below code.

    Display mdisp = getWindowManager().getDefaultDisplay();
    int maxX= mdisp.getWidth();
    int maxY= mdisp.getHeight();

(x,y) :-

1) (0,0) is top left corner.

2) (maxX,0) is top right corner

3) (0,maxY) is bottom left corner

4) (maxX,maxY) is bottom right corner

here maxX and maxY are screen maximum height and width in pixels, which we have retrieved in above given code.

If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:

final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        super.applyTransformation(interpolatedTime, t);
        // Do relevant calculations here using the interpolatedTime that runs from 0 to 1
        v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
    }};
anim.setDuration(500);
v.startAnimation(anim);

if (filter_section.getVisibility() == View.GONE) {
    filter_section.animate()
            .translationY(filter_section.getHeight()).alpha(1.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationStart(Animator animation) {
                    super.onAnimationStart(animation);
                    filter_section.setVisibility(View.VISIBLE);
                    filter_section.setAlpha(0.0f);
                }
            });
} else {
    filter_section.animate()
            .translationY(0).alpha(0.0f)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    super.onAnimationEnd(animation);
                    filter_section.setVisibility(View.GONE);
                }
            });
}

In the case of nested tables, some DBMS require to use an alias like MySQL and Oracle but others do not have such a strict requirement, but still allow to add them to substitute the result of the inner query.

If you want an ANSI SQL-92 version:

select view_definition from information_schema.views where table_name = 'view_name';

val() returns the value of the <select> element, i.e. the value attribute of the selected <option> element.

Since you actually want the inner text of the selected <option> element, you should match that element and use text() instead:

var nationality = $("#dancerCountry option:selected").text();

This will work for most of the website names :

SELECT ID, REVERSE(PARSENAME(REVERSE(WebsiteName), 2)) FROM dbo.YourTable .....

You can remove public keyword from your functions, because, you have to define a class in order to declare public, private or protected function

The easiest way in most situations is margin.

Where you can do :

button{
  margin: 13px 12px 12px 10px;
}

OR

button{
  margin: 13px;
}

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

import cats.implicits._

"Alphabet".toLowerCase().map(c => Map(c -> 1)).toList.combineAll
"Alphabet".toLowerCase().map(c => Map(c -> 1)).toList.foldMap(identity)

Cohesion in software engineering, as in real life, is how much the elements consisting a whole(in our case let's say a class) can be said that they actually belong together. Thus, it is a measure of how strongly related each piece of functionality expressed by the source code of a software module is.

One way of looking at cohesion in terms of OO is if the methods in the class are using any of the private attributes.

Now the discussion is bigger than this but High Cohesion (or the cohesion's best type - the functional cohesion) is when parts of a module are grouped because they all contribute to a single well-defined task of the module.

Coupling in simple words, is how much one component (again, imagine a class, although not necessarily) knows about the inner workings or inner elements of another one, i.e. how much knowledge it has of the other component.

Loose coupling is a method of interconnecting the components in a system or network so that those components, depend on each other to the least extent practically possible…

I wrote a blog post about this. It discusses all this in much detail, with examples etc. It also explains the benefits of why you should follow these principles.

I got this to work as follows:

First ensure that in your dataTable definition your aoColumns array includes sWidth data expressed as a % not fixed pixels or ems. Then ensure you have set the bAutoWidth property to false Then add this little but of JS:

update_table_size = function(a_datatable) {
  if (a_datatable == null) return;
  var dtb;
  if (typeof a_datatable === 'string') dtb = $(a_datatable)
  else dtb = a_datatable;
  if (dtb == null) return;

  dtb.css('width', dtb.parent().width());
  dtb.fnAdjustColumSizing();
}

$(window).resize(function() {
  setTimeout(function(){update_table_size(some_table_selector_or_table_ref)}, 250);
});

Works a treat and my table cells handle the white-space: wrap; CSS (which wasn't working without setting the sWidth, and was what led me to this question.)

If you create Makefile in the VSCode, your makefile doesnt run. I don't know the cause of this issue. Maybe the configuration of the file is not added to system. But I solved this way. delete created makefile, then go to project directory and right click mouse later create a file and named Makefile. After fill the Makefile and run it. It will work.

I suggest you first call shutil.copytree, and if an exception is thrown, then retry with shutil.copy.

import shutil, errno

def copyanything(src, dst):
    try:
        shutil.copytree(src, dst)
    except OSError as exc: # python >2.5
        if exc.errno == errno.ENOTDIR:
            shutil.copy(src, dst)
        else: raise

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

The problem with taking IEnumerable as a parameter is that it tells callers "I wish to enumerate this". It doesn't tell them how many times you wish to enumerate.

I can change the objects parameter to be List and then avoid the possible multiple enumeration but then I don't get the highest object that I can handle.

The goal of taking the highest object is noble, but it leaves room for too many assumptions. Do you really want someone to pass a LINQ to SQL query to this method, only for you to enumerate it twice (getting potentially different results each time?)

The semantic missing here is that a caller, who perhaps doesn't take time to read the details of the method, may assume you only iterate once - so they pass you an expensive object. Your method signature doesn't indicate either way.

By changing the method signature to IList/ICollection, you will at least make it clearer to the caller what your expectations are, and they can avoid costly mistakes.

Otherwise, most developers looking at the method might assume you only iterate once. If taking an IEnumerable is so important, you should consider doing the .ToList() at the start of the method.

It's a shame .NET doesn't have an interface that is IEnumerable + Count + Indexer, without Add/Remove etc. methods, which is what I suspect would solve this problem.

You should be able to do it simply by adding a -r

wget -r http://stackoverflow.com/

You can use the "-r" option to set the sender address:

mailx -r [email protected] -s ...

This gets the file type as from the last character (so avoids the problem with dots in file names)

Function getFileType(fn As String) As String

''get last instance of "." (full stop) in a filename then returns the part of the filename starting at that dot to the end
Dim strIndex As Integer
Dim x As Integer
Dim myChar As String

strIndex = Len(fn)
For x = 1 To Len(fn)

    myChar = Mid(fn, strIndex, 1)

    If myChar = "." Then
        Exit For
    End If

    strIndex = strIndex - 1

Next x

getFileType = UCase(Mid(fn, strIndex, Len(fn) - x + 1))

End Function

I used this for python 3.5. I did it using subprocess module.Using the password like this is very insecure.

The subprocess module takes command as a list of strings so either create a list beforehand using split() or pass the whole list later. Read the documentation for more information.

What we are doing here is echoing the password and then using pipe we pass it on to the sudo through '-S' argument.

#!/usr/bin/env python
import subprocess

sudo_password = 'mysecretpass'
command = 'apach2ctl restart'
command = command.split()

cmd1 = subprocess.Popen(['echo',sudo_password], stdout=subprocess.PIPE)
cmd2 = subprocess.Popen(['sudo','-S'] + command, stdin=cmd1.stdout, stdout=subprocess.PIPE)

output = cmd2.stdout.read().decode() 

You're better off looking at argparse for argument parsing.

http://docs.python.org/dev/library/argparse.html

Just makes it easy, no need to do the heavy lifting yourself.

sometimes even after clearing borders.

the reason is that you have images inside the td, giving the images display:block solves it.

To populate the column during insert, use a DEFAULT value:

CREATE TABLE users (
  id serial not null,
  firstname varchar(100),
  middlename varchar(100),
  lastname varchar(100),
  email varchar(200),
  timestamp timestamp default current_timestamp
)

Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT statement. If you want to prevent that you do need a trigger.

You also need a trigger if you need to update that column whenever the row is updated (as mentioned by E.J. Brennan)

Note that using reserved words for column names is usually not a good idea. You should find a different name than timestamp

Send User to Settings With located Package, example for WRITE_SETTINGS permission:

startActivityForResult(new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS).setData(Uri.parse("package:"+getPackageName()) ),0);

Some of more advanced Oracle database features such as session trace do not work properly in Oracle 11g XE 32-bit if installed on Windows 64-bit system. I needed session trace on Windows 7 64-bit.

Apart from that it works well for me in multiple production MS Windows 64-bit systems: Windows Server 2008 R2 and Windows Server 2003 R2.

You need access to the object.... you can't simply ask the form class....

eg...

you would of done some thing like

Form1.txtLog.Text = "blah"

instead of

Form1 blah = new Form1();
blah.txtLog.Text = "hello"

Best way to do this, just call CallingFragmentName fragment = (CallingFragmentName) viewPager .getAdapter() .instantiateItem(viewPager, viewPager.getCurrentItem()); It will re-instantiate your calling Fragment, so that it will not throw null pointer exception and call any method of that fragment.

Click on Project settings which you want to delete-->General project settings-->Expand-->Advanced settings-->Remove project.

You can use STL copy with O(M) performance when M is the size of the subvector.

As it turns out, Git is smart enough not to drop a stash if it doesn't apply cleanly. I was able to get to the desired state with the following steps:

1. To unstage the merge conflicts: git reset HEAD . (note the trailing dot)
2. To save the conflicted merge (just in case): git stash
3. To return to master: git checkout master
4. To pull latest changes: git fetch upstream; git merge upstream/master
5. To correct my new branch: git checkout new-branch; git rebase master
6. To apply the correct stashed changes (now 2nd on the stack): git stash apply stash@{1}

Firstly, I don't think spaces for an id is valid.

So i'd change the id to not include spaces.

<label year="2010" month="6" id="currentMonth"> June &nbsp;2010</label>

then the jquery code is simple (keep in mind, its better to fetch the jquery object once and use over and over agian)

var label = $('#currentMonth');
var month = label.attr('month');
var year = label.attr('year');
var text = label.text();

These paradigms don't have to be mutually exclusive. If you look at python, it supports functions and classes, but at the same time, everything is an object, including functions. You can mix and match functional/oop/procedural style all in one piece of code.

What I mean is, in functional languages (at least in Haskell, the only one I studied) there are no statements! functions are only allowed one expression inside them!! BUT, functions are first-class citizens, you can pass them around as parameters, along with a bunch of other abilities. They can do powerful things with few lines of code.

While in a procedural language like C, the only way you can pass functions around is by using function pointers, and that alone doesn't enable many powerful tasks.

In python, a function is a first-class citizen, but it can contain arbitrary number of statements. So you can have a function that contains procedural code, but you can pass it around just like functional languages.

Same goes for OOP. A language like Java doesn't allow you to write procedures/functions outside of a class. The only way to pass a function around is to wrap it in an object that implements that function, and then pass that object around.

In Python, you don't have this restriction.

foreach (Control field in container.Controls)
            {
                if (field is TextBox)
                    ((TextBox)field).Clear();
                else if (field is ComboBox)
                    ((ComboBox)field).SelectedIndex=0;
                else
                    dgView.DataSource = null;
                    ClearAllText(field);
            }

The density plot can also be created by using matplotlib: The function plt.hist(data) returns the y and x values necessary for the density plot (see the documentation https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.hist.html). Resultingly, the following code creates a density plot by using the matplotlib library:

import matplotlib.pyplot as plt
dat=[-1,2,1,4,-5,3,6,1,2,1,2,5,6,5,6,2,2,2]
a=plt.hist(dat,density=True)
plt.close()
plt.figure()
plt.plot(a[1][1:],a[0])      

This code returns the following density plot

As far as I understand, you create a Movie class:

class Movie
{
private:
  std::string _title;
  std::string _director;
  int         _year;
  int         _rating;
  std::vector<std::string> actors;
};

and having such class, you create a vector instance:

std::vector<Movie*> movies;

so, you can add any movie to your movies collection. Since you are creating a vector of pointers to movies, do not forget to free the resources allocated by your movie instances OR you could use some smart pointer to deallocate the movies automatically:

std::vector<shared_ptr<Movie>> movies;

OK realized a mistake .. it has to be /:id/:id2

Anyway didn't find this in any tutorial or other StackOverflow question.

@RouteConfig([{path: '/component/:id/:id2',name: 'MyCompB', component:MyCompB}])
export class MyCompA {
    onClick(){
        this._router.navigate( ['MyCompB', {id: "someId", id2: "another ID"}]);
    }
}

For me, the menu item Inspect Devices wasn't available (not shown at all). But, simply browsing to chrome://inspect/#devices showed me my device and I was able to use the port forward etc. I have no idea why the menu item is not displayed.

I think the best example (along with explanations) you can find on the oracle website : here. Another good tuturial could be found here.

vb.net version

Me.Background = CType(New BrushConverter().ConvertFrom("#ffaacc"), SolidColorBrush)

Here's a method if you want to do it for just one specific file:

RewriteRule ^about$ about.php [L]

Ref: http://css-tricks.com/snippets/htaccess/remove-file-extention-from-urls/

Expanding on the bitset answer:

#include <iostream>
#include <bitset>
#include <string>

using namespace std;
int main() {
  bitset<8> byte(std::string("10010011");

  // Set Bit
  byte.set(3); // 10010111

  // Clear Bit
  byte.reset(2); // 10010101

  // Toggle Bit
  byte.flip(7); // 00010101

  cout << byte << endl;

  return 0;
}

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

https://wordpress.org/plugins/woocommerce-products-filter/

This one seems to do exactly what you are after

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

Your example is not an override. Overrides technically occur in a subclass, but in this example the contructor method is replaced in the original class.

the style is:

<style type="text/css">
 .topcorner{
   position:absolute;
   top:0;
   right:0;
  }
</style>

hope it will work. Thanks

Try this code, works 100% for me:
FOR Landscape:

<head>
<style type="text/css">

@page{
  size: auto A4 landscape;
  margin: 3mm;
}

</style>
</head>

FOR Portait:

<head>
<style type="text/css">

@page{
  size: auto;
  margin: 3mm;
}

</style>
</head>

This means we are not able to instantiate ES transportClient and throw this exception. There are couple of possibilities that cause this issue.

• Cluster name is incorrect. So open ES_HOME_DIR/config/elasticserach.yml file and check the cluster name value OR use this command: curl -XGET 'http://localhost:9200/_nodes'
• Verify port 9200 is http port but elasticsearch service is using tcp port 9300 [by default]. So verify that the port is not blocked.

• Authentication issue: set the header in transportClient's context for authentication:

  client.threadPool().getThreadContext()
    .putHeader("Authorization", "Basic " + encodeBase64String(basicHeader.getBytes()));
  

If you are still facing this issue then add the following property:

put("client.transport.ignore_cluster_name", true)

The below basic code is working fine for me:

Settings settings = Settings.builder()
            .put("cluster.name", "my-application").put("client.transport.sniff", true).put("client.transport.ignore_cluster_name", false).build();
    TransportClient client = new PreBuiltTransportClient(settings).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

You can also use a regular expression as a field separator. The following will print "bar" by using a regular expression to set the number "10" as a separator.

echo "foo 10 bar" | awk -F'[0-9][0-9]' '{print $2}'

Did you set the proper settings in pg_hba.conf?

See https://help.ubuntu.com/stable/serverguide/postgresql.html how to do it.

completed = (id) => {
    var details = {
        'id': id,

    };

    var formBody = [];
    for (var property in details) {
        var encodedKey = encodeURIComponent(property);
        var encodedValue = encodeURIComponent(details[property]);
        formBody.push(encodedKey + "=" + encodedValue);
    }
    formBody = formBody.join("&");

    fetch(markcompleted, {
        method: 'POST',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/x-www-form-urlencoded'
        },
        body: formBody
    })
        .then((response) => response.json())
        .then((responseJson) => {
            console.log(responseJson, 'res JSON');
            if (responseJson.status == "success") {
                console.log(this.state);
                alert("your todolist is completed!!");
            }
        })
        .catch((error) => {
            console.error(error);
        });
};

jQuery's :selected selector is probably what you are looking for.

For styles wp_register_style( 'namespace', 'http://locationofcss.com/mycss.css' );

Then use: wp_enqueue_style('namespace'); wherever you want the css to load.

Scripts are as above but the quicker way for loading jquery is just to use enqueue loaded in an init for the page you want it to load on: wp_enqueue_script('jquery');

Unless of course you want to use the google repository for jquery.

You can also conditionally load the jquery library that your script is dependent on:

wp_enqueue_script('namespaceformyscript', 'http://locationofscript.com/myscript.js', array('jquery'));

Update Sept. 2017

I wrote this answer a while ago. I should clarify that the best place to enqueue your scripts and styles is within the wp_enqueue_scripts hook. So for example:

add_action('wp_enqueue_scripts', 'callback_for_setting_up_scripts');
function callback_for_setting_up_scripts() {
    wp_register_style( 'namespace', 'http://locationofcss.com/mycss.css' );
    wp_enqueue_style( 'namespace' );
    wp_enqueue_script( 'namespaceformyscript', 'http://locationofscript.com/myscript.js', array( 'jquery' ) );
}

The wp_enqueue_scripts action will set things up for the "frontend". You can use the admin_enqueue_scripts action for the backend (anywhere within wp-admin) and the login_enqueue_scripts action for the login page.

See this link. It shows you how to dynamically create variables in PowerShell.

Here is the basic idea:

Use New-Variable and Get-Variable,

for ($i=1; $i -le 5; $i++)
{
    New-Variable -Name "var$i" -Value $i
    Get-Variable -Name "var$i" -ValueOnly
}

(It is taken from the link provided, and I don't take credit for the code.)

Not answering to your direct questions, since there are already a lot of detailed answers, but it's worth mentioning, that to the contrary of Android documentation, Android Studio is suggesting to use the same version for compileSDKVersion and targetSDKVersion.

It’s quite common to define navigational properties in a model to be virtual. When a navigation property is defined as virtual, it can take advantage of certain Entity Framework functionality. The most common one is lazy loading.

Lazy loading is a nice feature of many ORMs because it allows you to dynamically access related data from a model. It will not unnecessarily fetch the related data until it is actually accessed, thus reducing the up-front querying of data from the database.

From book "ASP.NET MVC 5 with Bootstrap and Knockout.js"

If the question isn't just "how to access an integer form of the timedelta?" but "how to convert the timedelta column in the dataframe to an int?" the answer might be a little different. In addition to the .dt.days accessor you need either df.astype or pd.to_numeric

Either of these options should help:

df['tdColumn'] = pd.to_numeric(df['tdColumn'].dt.days, downcast='integer')

or

df['tdColumn'] = df['tdColumn'].dt.days.astype('int16')

In case you are willing to use Curl for the calls with JSON 2 and Spring 3.2.0 in hand checkout the FAQ here. As AnnotationMethodHandlerAdapter is deprecated and replaced by RequestMappingHandlerAdapter.

Explanation from the bottom for ones who came here without any knowledge of branches.

Basic master branch development logic is: You work only on another branches and use master only to merge another branches.

You begin to create a new branch in this way:

1. Clone repository in your local dir (or create a new repository):

$ cd /var/www
$ git clone [email protected]:user_name/repository_name.git

2. Create a new branch. It will contain the latest files of your master branch repository

$ git branch new_branch

3. Change your current git branch to the new_branch

$ git checkout new_branch

4. Do coding, commits, as usual…

$ git add .
$ git commit -m “Initial commit”
$ git push # pushes commits only to “new_branch”

5. When job is finished on this branch, merge with “master” branch:

$ git merge master
$ git checkout master # goes to master branch
$ git merge development # merges files in localhost. Master shouldn’t have any  commits ahead, otherwise there will be a need for pull and merging code by hands!
$ git push # pushes all “new_branch” commits to both branches - “master” and “new_branch”

I also recommend using the Sourcetree App to see visual tree of changes and branches.

FOR SQLALCHEMY AND PYTHON

The encoding used for Unicode has traditionally been 'utf8'. However, for MySQL versions 5.5.3 on forward, a new MySQL-specific encoding 'utf8mb4' has been introduced, and as of MySQL 8.0 a warning is emitted by the server if plain utf8 is specified within any server-side directives, replaced with utf8mb3. The rationale for this new encoding is due to the fact that MySQL’s legacy utf-8 encoding only supports codepoints up to three bytes instead of four. Therefore, when communicating with a MySQL database that includes codepoints more than three bytes in size, this new charset is preferred, if supported by both the database as well as the client DBAPI, as in:

e = create_engine(
    "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4")
All modern DBAPIs should support the utf8mb4 charset.

Here's the exact definition of UsedRange (MSDN reference) :

Every Worksheet object has a UsedRange property that returns a Range object representing the area of a worksheet that is being used. The UsedRange property represents the area described by the farthest upper-left and farthest lower-right nonempty cells in a worksheet and includes all cells in between.

So basically, what that line does is :

1. .UsedRange -> "Draws" a box around the outer-most cells with content inside.
2. .Columns -> Selects the entire columns of those cells
3. .Count -> Returns an integer corresponding to how many columns there are (in this selection)
4. - 8 -> Subtracts 8 from the previous integer.

I assume VBA calculates the UsedRange by finding the non-empty cells with lowest and highest index values.

Most likely, you're getting an error because the number of lines in your range is smaller than 3, and therefore the number returned is negative.

The article Semicolons in JavaScript are optional makes some really good points about not using semi colons in Javascript. It deals with all the points have been brought up by the answers to this question.

You can do that using the SimpleDateFormat class.

SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

String dates=formatter.format(mydate);
//mydate is your date object

This seems to be due to a problem in the UITableViewController subclass template. It comes with a version of the prepareForSegue method that would require you to unwrap the segue.

Replace your current prepareForSegue function with:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "Load View") {
        // pass data to next view
    }
}

This version implicitly unwraps the parameters, so you should be fine.

i found following code working for ckeditor 5

ClassicEditor
    .create( document.querySelector( '#editor' ) )
    .then( editor => {
        editor.model.document.on( 'change:data', () => {
            editorData = editor.getData();
        } );
    } )
    .catch( error => {
        console.error( error );
    } );

[^] ( within [ ] ) is negation in regular expression whereas ^ is "begining of string"

[^a-z] matches any single character that is not from "a" to "z"

^[a-z] means string starts with from "a" to "z"

Reference

Use:

boolean(/*/*[@subjectIdentifier="Primary"]/*/*/*/*
                           [name()='AttachedXml' 
                          and 
                            namespace-uri()='http://xml.mycompany.com/XMLSchema'
                           ]
       )

An alternative way you can do this, is using dictionary comprehension. This should be compatible with 2.7+

result = {
    key: value for key, value in
    {"foo": "bar", "lorem": None}.items()
    if value
}

Look at the yesno helper

Eg:

{{ myValue|yesno:"itwasTrue,itWasFalse,itWasNone" }}

I had a similar problem. In my case, the version of testng in my .m2/repositories folder was corrupt, but when I deleted it & did a maven update again, everything worked fine.

Within MySQL work bench perform the following:

1. Click Server > Data Export

2. In the Object Selection Tab select the desired schema.

3. Next, select the desired tables using the list box to the right of the schema.

4. Select a file location to export the script.

5. Click Finish.

6. Navigate to the newly created file and copy the insert statements.

Strings with dates are comparable in JavaScript (if they are syntactically the same), e.g.:

'2020-12-01' < '2020-12-02' == true

This means you can use this expression in a custom sort function:

var arr = [{id:1, date:'2020-12-01'}, {id:1, date:'2020-12-15'}, {id:1, date:'2020-12-12'}]

function sortByDate(a, b) {
    if (a.date < b.date) {
        return 1;
    }
    if (a.date > b.date) {
        return -1;
    }
    return 0;
}

const sorted = arr.sort(sortByDate);
console.log(sorted);

I've found the same problem. I lost almost a day trying to start a service from OnClickListener method - outside the onCreate and after 1 day, I still failed!!!! Very frustrating! I was looking at the sample example RemoteServiceController. Theirs works, but my implementation does not work!

The only way that was working for me, was from inside onCreate method. None of the other variants worked and believe me I've tried them all.

Conclusion:

• If you put your service class in different package than the mainActivity, I'll get all kind of errors

• Also the one "/" couldn't find path to the service, tried starting with Intent(package,className) and nothing , also other type of Intent starting

• I moved the service class in the same package of the activity Final form that works

• Hopefully this helps someone by defining the listerners onClick inside the onCreate method like this:

  public void onCreate() {
  //some code......
      Button btnStartSrv  = (Button)findViewById(R.id.btnStartService);
      Button btnStopSrv  = (Button)findViewById(R.id.btnStopService);
  
      btnStartSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              startService(new Intent("RM_SRV_AIDL"));
          }
      });
  
      btnStopSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              stopService(new Intent("RM_SRV_AIDL"));
          }
      });
  
  } // end onCreate
  

Also very important for the Manifest file, be sure that service is child of application:

<application ... >
    <activity ... >
     ...
    </activity>
    <service
        android:name="com.mainActivity.MyRemoteGPSService"
        android:label="GPSService"
        android:process=":remote">

        <intent-filter>
             <action android:name="RM_SRV_AIDL" />
        </intent-filter>
    </service>
</application>

Here is an example of reading and writing a list of objects of type SNStock that implements NSCoding - we have an accessor for the entire list, watchlist, and two methods to add and remove objects, that is addStock(stock: SNStock) and removeStock(stock: SNStock).

import Foundation

class DWWatchlistController {

  private let kNSUserDefaultsWatchlistKey: String = "dw_watchlist_key"

  private let userDefaults: NSUserDefaults

  private(set) var watchlist:[SNStock] {

    get {
      if let watchlistData : AnyObject = userDefaults.objectForKey(kNSUserDefaultsWatchlistKey) {
        if let watchlist : AnyObject = NSKeyedUnarchiver.unarchiveObjectWithData(watchlistData as! NSData) {
          return watchlist as! [SNStock]
        }
      }
      return []
    }

    set(watchlist) {
      let watchlistData = NSKeyedArchiver.archivedDataWithRootObject(watchlist)
      userDefaults.setObject(watchlistData, forKey: kNSUserDefaultsWatchlistKey)
      userDefaults.synchronize()
    }
  }

  init() {
    userDefaults = NSUserDefaults.standardUserDefaults()
  }

  func addStock(stock: SNStock) {
    var watchlist = self.watchlist
    watchlist.append(stock)
    self.watchlist = watchlist
  }

  func removeStock(stock: SNStock) {
    var watchlist = self.watchlist
    if let index = find(watchlist, stock) {
      watchlist.removeAtIndex(index)
      self.watchlist = watchlist
    }
  }

}

Remember that your object needs to implement NSCoding or else the encoding won't work. Here is what SNStock looks like:

import Foundation

class SNStock: NSObject, NSCoding
{
  let ticker: NSString
  let name: NSString

  init(ticker: NSString, name: NSString)
  {
    self.ticker = ticker
    self.name = name
  }

  //MARK: NSCoding

  required init(coder aDecoder: NSCoder) {
    self.ticker = aDecoder.decodeObjectForKey("ticker") as! NSString
    self.name = aDecoder.decodeObjectForKey("name") as! NSString
  }

  func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(ticker, forKey: "ticker")
    aCoder.encodeObject(name, forKey: "name")
  }

  //MARK: NSObjectProtocol

  override func isEqual(object: AnyObject?) -> Bool {
    if let object = object as? SNStock {
      return self.ticker == object.ticker &&
        self.name == object.name
    } else {
      return false
    }
  }

  override var hash: Int {
    return ticker.hashValue
  }
}

Hope this helps!

you can show the file selection dialog with a onclick function, and if a file is choosen (onchange event) then send the form to upload the file

 <form id='foto' method='post' action='upload' method="POST"  enctype="multipart/form-data" >
  <div style="height:0px;overflow:hidden"> 
  <input type="file" id="fileInput" name="fileInput" onchange="this.form.submit()"/> 
  </div>

  <i class='fa fa-camera' onclick="fileInput.click();"></i>
</form> 

Here's what I do, remember that "all" and "any" accepts an iterable, so I just put a long condition in a list and let "all" do the work.

condition = [cond1 == 'val1', cond2 == 'val2', cond3 == 'val3', cond4 == 'val4']

if all(condition):
   do_something

If you are making a console window program, you can use system("pause");

Not sure from what version, but I use 1.3.14 and you can just use:

window.location.href = '/employee/1';

No need to inject $location or $window in the controller and no need to get the current host address.

this is what it worked for me I'm using html2pdf from an Angular2 app, so I made a reference to this function in the controller

var html2pdf = (function(html2canvas, jsPDF) {

declared in html2pdf.js.

So I added just after the import declarations in my angular-controller this declaration:

declare function html2pdf(html2canvas, jsPDF): any;

then, from a method of my angular controller I'm calling this function:

generate_pdf(){
    this.someService.loadContent().subscribe(
      pdfContent => {
        html2pdf(pdfContent, {
          margin:       1,
          filename:     'myfile.pdf',
          image:        { type: 'jpeg', quality: 0.98 },
          html2canvas:  { dpi: 192, letterRendering: true },
          jsPDF:        { unit: 'in', format: 'A4', orientation: 'portrait' }
        });
      }
    );
  }

Hope it helps

Pig allows one to load data and user code at any point in the pipeline. This is can be particularly important if the data is a streaming data, for example data from satellites or instruments.

Hive, which is RDBMS based, needs the data to be first imported (or loaded) and after that it can be worked upon. So if you were using Hive on streaming data, you would have to keep filling buckets (or files) and use hive on each filled bucket, while using other buckets to keep storing the newly arriving data.

Pig also uses lazy evaluation. It allows greater ease of programming and one can use it to analyze data in different ways with more freedom than in an SQL like language like Hive. So if you really wanted to analyze matrices or patterns in some unstructured data you had, and wanted to do interesting calculations on them, with Pig you can go some fair distance, while with Hive, you need something else to play with the results.

Pig is faster in the data import but slower in actual execution than an RDBMS friendly language like Hive.

Pig is well suited to parallelization and so it possibly has an edge for systems where the datasets are huge, i.e. in systems where you are concerned more about the throughput of your results than the latency (the time to get any particular datum of result).

1. Create "root" package (folder) in your project, for example.

   package source; (.../path_to_project/source/)

2. Move YourClass.class into a source folder. (.../path_to_project/source/YourClass.class)

3. Import like this

   import source.YourClass;

If you still see permission denied after verifying the permissions of the parent folders, it may be SELinux restricting access.

To check if SELinux is running:

# getenforce

To disable SELinux until next reboot:

# setenforce Permissive

Restart Nginx and see if the problem persists. To allow nginx to serve your www directory (make sure you turn SELinux back on before testing this. i.e, setenforce Enforcing)

# chcon -Rt httpd_sys_content_t /path/to/www

See my answer here for more details

Looking at the "effective POM" will probably help too. For instance, if you wanted to know what the path is for ${project.build.sourceDirectory}

you would find the related XML in the effective POM, such as: <project> <build> <sourceDirectory>/my/path</sourceDirectory>

Also helpful - you can do a real time evaluation of properties via the command line execution of mvn help:evaluate while in the same dir as the POM.

If you want to do it without using a separate variable then

$("#myForm").data('validator').resetForm();

You can specify how many migrations to roll back to using the 'step' option:

php artisan migrate:rollback --step=1

Some tricks are available here:

• Step 1: Download NSSM
• Step 2: Install your sevice with nssm.exe install [serviceName]
• Step 3: This will open a GUI which you will use to locate your executable

I understand what you want. You want to check every data of the array if all of it is empty or at least 1 is not empty

Empty array

Array ( [Tags] => SimpleXMLElement Object ( [0] => ) )

Not an Empty array

Array ( [Tags] => SimpleXMLElement Object ( [0] =>,[1] => "s" ) )

I hope I am right. You can use this function to check every data of an array if at least 1 of them has a value.

/*
 return true if the array is not empty
 return false if it is empty
*/
function is_array_empty($arr){
  if(is_array($arr)){     
      foreach($arr $key => $value){
          if(!empty($value) || $value != NULL || $value != ""){
              return true;
              break;//stop the process we have seen that at least 1 of the array has value so its not empty
          }
      }
      return false;
  }
}

if(is_array_empty($result['Tags'])){
    //array is not empty
}else{
    //array is empty
}

Hope that helps.

I would like to mention the key before writing the code for your consideration.

//Key

temp= address of new node allocated by malloc function (member od alloc.h library in C )

prev= address of last node of existing link list.

next = contains address of next node

struct node {
    int data;
    struct node *next;
} *head;

void addnode_end(int a) {
    struct node *temp, *prev;
    temp = (struct node*) malloc(sizeof(node));
    if (temp == NULL) {
        cout << "Not enough memory";
    } else {
        node->data = a;
        node->next = NULL;
        prev = head;

        while (prev->next != NULL) {
            prev = prev->next;
        }

        prev->next = temp;
    }
}

This is what I came up with. There is an added function to check to see if the int is past the date on which the exceptions were imposed(year$100, year %400). Before 1582 those exceptions weren't around.

import java.util.Scanner;

public class lecture{


public static void main(String[] args) {
    boolean loop=true;
    Scanner console = new Scanner( System.in );
    while (loop){
        System.out.print( "Enter the year: " );

        int year= console.nextInt();
        System.out.println( "The year is a leap year: "+ leapYear(year) );
        System.out.print( "again?: " );
        int again = console.nextInt();
        if (again == 1){
            loop=false;
        }//if
    }
}
public static boolean leapYear ( int year){
    boolean leaped = false;
    if (year%4==0){
        leaped = true;
        if(year>1582){
            if (year%100==0&&year%400!=0){
                leaped=false;
            }
        }
    }//1st if
    return leaped;
}
} 

a void* is a pointer, but the type of what it points to is unspecified. When you pass a void pointer to a function you will need to know what its type was in order to cast it back to that correct type later in the function to use it. You will see examples in pthreads that use functions with exactly the prototype in your example that are used as the thread function. You can then use the void* argument as a pointer to a generic datatype of your choosing and then cast it back to that type to use within your thread function. You need to be careful when using void pointers though as unless you case back to a pointer of its true type you can end up with all sorts of problems.

There is an eclipse.ini (sts.ini) parameter that can help:

-Djava.net.useSystemProxies=true

A lot of effort wasted on this trivial setting each time I change the work environment... See one of the related bugs on eclipse bugzilla.

You need to assign different classes to each table.

Create a class in CSS with the dot '.' operator and write your properties inside each class. For example,

.table1 {
//some properties
}

.table2 {
//Some other properties
}

and use them in your html code.

It means your previous activity in stack when you start this activity. Add finish(); after the line in which you calling this activity.

In your all previous activity. when you start new activity like-

startActivity(I);

Add finish(); after this.

To remove some key value pair form object array uses Postgres SQL as database like this example:

This is user function return user details object, we have to remove "api_secret" key from rows :

    function getCurrentUser(req, res, next) { // user function
    var userId = res.locals.userId;
    console.log(userId)
    db.runSQLWithParams("select * from users where id = $1", [userId], function(err, rows) {
      if(err){
        console.log(err)
      }
      var responseObject = {
        _embedded: rows,
      }
      responseObject._embedded[0].api_secret = undefined
      // console.log(api);
      // console.log(responseObject);
      res.json(responseObject);
    }); 
}

The above function return below object as JSON response before

 {
    "_embedded": [
        {
            "id": "0123abd-345gfhgjf-dajd4456kkdj",
            "secret_key: "secret",
            "email": "[email protected]",
            "created": "2020-08-18T00:13:16.077Z"
        }
    ]
}

After adding this line responseObject._embedded[0].api_secret = undefined It gives below result as JSON response:

{
        "_embedded": [
            {
                "id": "0123abd-345gfhgjf-dajd4456kkdj",
                "email": "[email protected]",
                "created": "2020-08-18T00:13:16.077Z"
            }
        ]
    }

There should be svn utility on you box, if installed:

$ svn checkout http://example.com/svn/somerepo somerepo

This will check out a working copy from a specified repository to a directory somerepo on our file system.

You may want to print commands, supported by this utility:

$ svn help

uname -a output in your question is identical to one, used by Parallels Virtuozzo Containers for Linux 4.0 kernel, which is based on Red Hat 5 kernel, thus your friends are rpm or the following command:

$ sudo yum install subversion

For Laravel 2020. Ok, an example:

<form class="modal-content animate" action="{{ url('login_kun')  }}" method="post">
  @csrf   // !!! attention - this string is a must 
....
 </form>

And then in web.php:

Route::post("/login_kun", "LoginController@login");

And one more in new created LoginController:

 public function login(Request $request){
    dd($request->all());
}

and you are done my friend.

Building on @loup's answer...

If you want to timeout a process and silence the kill job/pid output, run:

( (sleep 1 && killall program 2>/dev/null) &) && program --version 

This puts the backgrounded process into a subshell so you don't see the job output.

Kind of a naive method to display code will be including it in a textarea and add disabled attribute so its not editable.

<textarea disabled> code </textarea>

Hope that help someone looking for an easy way to get stuff done..

In my case, my running php version is 7.1.x on mac OSX . I installed intl command using brew install php71-intl. Placing extension=intl.so inside php.ini was no effect at all. Finally i looked for extension installed directory and there i saw intl.so and placed that path (extension=/usr/local/Cellar/php71-intl/7.1.11_20/intl.so) to my php.ini file and it solved my problem.

If searching for a value, you will have to loop through all the data. But to minimize code involved, you can use LINQ.

Example:

Given Dictionary defined as following:

Dictionary<Int32, String> dict;

You can use following code :

// Search for all keys with given value
Int32[] keys = dict.Where(kvp => kvp.Value.Equals("SomeValue")).Select(kvp => kvp.Key).ToArray();
        
// Search for first key with given value
Int32 key = dict.First(kvp => kvp.Value.Equals("SomeValue")).Key;

Either use casting as others have already said, or multiply one of the int variables by 1.0:

double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));

Here is a quick and easy solution:

CREATE FUNCTION dbo.vaValidEmail(@EMAIL varchar(100))

RETURNS bit as
BEGIN     
  DECLARE @bitRetVal as Bit
  IF (@EMAIL <> '' AND @EMAIL NOT LIKE '_%@__%.__%')
     SET @bitRetVal = 0  -- Invalid
  ELSE 
    SET @bitRetVal = 1   -- Valid
  RETURN @bitRetVal
END 

Then you can find all rows by using the function:

SELECT * FROM users WHERE dbo.vaValidEmail(email) = 0

If you are not happy with creating a function in your database, you can use the LIKE-clause directly in your query:

SELECT * FROM users WHERE email NOT LIKE '_%@__%.__%'

Just got the same issue after installing Developer Tools Microsoft ASP.NET and Web Tools 2015 (Beta7). I tried to reinstall ASP.NET Project Templates but it didn't help.

While looking into "Add / remove programs" -> "Visual 2015" -> "Modify" , I found the "Web developer tools" unchecked. This SO answer helps me to figure this.

After reinstalling this, everything reappears

With string type columns like character(2) (as you mentioned later), the displayed concatenation just works because, quoting the manual:

[...] the string concatenation operator (||) accepts non-string input, so long as at least one input is of a string type, as shown in Table 9.8. For other cases, insert an explicit coercion to text [...]

Bold emphasis mine. The 2nd example (select a||', '||b from foo) works for any data types since the untyped string literal ', ' defaults to type text making the whole expression valid in any case.

For non-string data types, you can "fix" the 1st statement by casting at least one argument to text. (Any type can be cast to text):

SELECT a::text || b AS ab FROM foo;

Judging from your own answer, "does not work" was supposed to mean "returns NULL". The result of anything concatenated to NULL is NULL. If NULL values can be involved and the result shall not be NULL, use concat_ws() to concatenate any number of values (Postgres 9.1 or later):

SELECT concat_ws(', ', a, b) AS ab FROM foo;

Or concat() if you don't need separators:

SELECT concat(a, b) AS ab FROM foo;

No need for type casts here since both functions take "any" input and work with text representations.

More details (and why COALESCE is a poor substitute) in this related answer:

• Combine two columns and add into one new column

Regarding update in the comment

+ is not a valid operator for string concatenation in Postgres (or standard SQL). It's a private idea of Microsoft to add this to their products.

There is hardly any good reason to use character(n) (synonym: char(n)). Use text or varchar. Details:

• Any downsides of using data type "text" for storing strings?
• Best way to check for "empty or null value"

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>

This works regardless of the size of its contents

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

Men, use this:

if(myWindow.closed){
    callback();
    return;
}

I had this problem even after setting the config properly. git config

My scenario was issuing git command through supervisor (in Linux). On further debugging, supervisor was not reading the git config from home folder. Hence, I had to set the environment HOME variable in the supervisor config so that it can locate the git config correctly. It's strange that supervisor was not able to locate the git config just from the username configured in supervisor's config (/etc/supervisor/conf.d).

Replace with

imageWidth = 1 * Convert.ToInt32(Label1.Text);

It is mentioned under "Index expressions".

An index expression on a map a of type map[K]V used in an assignment or initialization of the special form

v, ok = a[x] 
v, ok := a[x] 
var v, ok = a[x]

yields an additional untyped boolean value. The value of ok is true if the key x is present in the map, and false otherwise.

dependencies {
    compile 'com.android.support:support-v4:19.1.+'
    compile fileTree(dir: 'libs', include: ['*.jar'])

This gets conflicted if you have the support jar in your libs folder. If you have the support jar in your project libs folder and you have the module dependency added to compile 'com.android.support:support-v4:13.0.+' the UNEXPECTED_TOPLEVEL_DEPENDANCY exception will be thrown.

This is the way i calculated the slope: Source: http://classroom.synonym.com/calculate-trendline-2709.html

class Program
    {
        public double CalculateTrendlineSlope(List<Point> graph)
        {
            int n = graph.Count;
            double a = 0;
            double b = 0;
            double bx = 0;
            double by = 0;
            double c = 0;
            double d = 0;
            double slope = 0;

            foreach (Point point in graph)
            {
                a += point.x * point.y;
                bx = point.x;
                by = point.y;
                c += Math.Pow(point.x, 2);
                d += point.x;
            }
            a *= n;
            b = bx * by;
            c *= n;
            d = Math.Pow(d, 2);

            slope = (a - b) / (c - d);
            return slope;
        }
    }

    class Point
    {
        public double x;
        public double y;
    }

if you are using eclipse goto DDMS and then file explorer there you will see System/Apps folder and the apks are there

Though there are a few non-Eclipse answers above for this question that does not mention Eclipse, they require path variable changes. An alternative is to use the command line option, java.home, e.g.:

mvn package -Djava.home="C:\Program Files\Java\jdk1.8.0_161\jre"

Notice the \jre at the end - a surprising necessity.

can gridmove be of any assistance?

very handy tool on larger screens...

Here is another alternative. Download it directly here: http://androidsdkoffline.blogspot.com.ng/p/android-sdk-tools.html.

The present version as of this writing is Android SDK Tools 25.1.7. Unzip it when the download is done and place it in your sdk folder. You can then download other missing files directly from the SDK Manager.

1. Create an instance of Random class somewhere. Note that it's pretty important not to create a new instance each time you need a random number. You should reuse the old instance to achieve uniformity in the generated numbers. You can have a static field somewhere (be careful about thread safety issues):

   static Random rnd = new Random();
   

2. Ask the Random instance to give you a random number with the maximum of the number of items in the ArrayList:

   int r = rnd.Next(list.Count);
   

3. Display the string:

   MessageBox.Show((string)list[r]);
   

Store it in a field of type long. See Date.getTime() and new Date(long)

Yes you can create events on objects, here is an example;

public class Foo
{
    public delegate void MyEvent(object sender, object param);
    event MyEvent OnMyEvent;

    public Foo()
    {
        this.OnMyEvent += new MyEvent(Foo_OnMyEvent);
    }

    void Foo_OnMyEvent(object sender, object param)
    {
        if (this.OnMyEvent != null)
        {
            //do something
        }
    }



    void RaiseEvent()
    {
        object param = new object();
        this.OnMyEvent(this,param);
    }
}

Bit rate is a measure of the number of data bits (that's 0's and 1's) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation 'bps'.

Baud rate by definition means the number of times a signal in a communications channel changes state. For example, a 2400 baud rate means that the channel can change states up to 2400 times per second. When I say 'change state' I mean that it can change from 0 to 1 up to 2400 times per second. If you think about this, it's pretty much similar to the bit rate, which in the above example was 2400 bps.

Whether you can transmit 2400 zeros or ones in one second (bit rate), or change the state of a digital signal up to 2400 times per second (baud rate), it the same thing.

Bulk add new categories to Woo:

Insert category id, name, url key

INSERT INTO wp_terms 
VALUES
  (57, 'Apples', 'fruit-apples', '0'),
  (58, 'Bananas', 'fruit-bananas', '0');

Set the term values as catergories

INSERT INTO wp_term_taxonomy 
VALUES
  (57, 57, 'product_cat', '', 17, 0),
  (58, 58, 'product_cat', '', 17, 0)

17 - is parent category, if there is one

key here is to make sure the wp_term_taxonomy table term_taxonomy_id, term_id are equal to wp_term table's term_id

After doing the steps above go to wordpress admin and save any existing category. This will update the DB to include your bulk added categories

The safest way would be bitwise OR ing your double with 0. Look at this XORing two doubles in Java

Basically you should do if ((Double.doubleToRawLongBits(foo.x) | 0 ) ) (if it is really 0)

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

sub selectVar ()
    dim x,y as integer
    let srange = "A" & x & ":" & "m" & y
    range(srange).select
end sub

I think this is the simplest way.

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

Ruby is pass-by-value in a strict sense, BUT the values are references.

This could be called "pass-reference-by-value". This article has the best explanation I have read: http://robertheaton.com/2014/07/22/is-ruby-pass-by-reference-or-pass-by-value/

Pass-reference-by-value could briefly be explained as follows:

A function receives a reference to (and will access) the same object in memory as used by the caller. However, it does not receive the box that the caller is storing this object in; as in pass-value-by-value, the function provides its own box and creates a new variable for itself.

The resulting behavior is actually a combination of the classical definitions of pass-by-reference and pass-by-value.

namespace ReverseString
{
    class Program
    {
        static void Main(string[] args)
        {
            string stat = "This is an example of code" +
                          "This code has written in C#\n\n";

            Console.Write(stat);

            char[] myArrayofChar = stat.ToCharArray();

            Array.Reverse(myArrayofChar);

            foreach (char myNewChar in myArrayofChar)
                Console.Write(myNewChar); // You just need to write the function
                                          // Write instead of WriteLine
            Console.ReadKey();
        }
    }
}

You can undo git add before commit with

git reset <file>

which will remove it from the current index (the "about to be committed" list) without changing anything else.

You can use

git reset

without any file name to unstage all due changes. This can come in handy when there are too many files to be listed one by one in a reasonable amount of time.

In old versions of Git, the above commands are equivalent to git reset HEAD <file> and git reset HEAD respectively, and will fail if HEAD is undefined (because you haven't yet made any commits in your repository) or ambiguous (because you created a branch called HEAD, which is a stupid thing that you shouldn't do). This was changed in Git 1.8.2, though, so in modern versions of Git you can use the commands above even prior to making your first commit:

"git reset" (without options or parameters) used to error out when you do not have any commits in your history, but it now gives you an empty index (to match non-existent commit you are not even on).

Documentation: git reset

line = line.Replace("\\", "");

I don't know of a platform independent way of doing it, but under Windows, if you use the msvcrt module, you can use its getch function:

import msvcrt
c = msvcrt.getch()
print 'you entered', c

mscvcrt also includes the non-blocking kbhit() function to see if a key was pressed without waiting (not sure if there's a corresponding curses function). Under UNIX, there is the curses package, but not sure if you can use it without using it for all of the screen output. This code works under UNIX:

import curses
stdscr = curses.initscr()
c = stdscr.getch()
print 'you entered', chr(c)
curses.endwin()

Note that curses.getch() returns the ordinal of the key pressed so to make it have the same output I had to cast it.

if (!myString.replace(/^\s+|\s+$/g,""))

Since you are learning Git, know that this has little to do with git but with the text editor configured for use. In vim, you can press i to start entering text and save by pressing esc and :wq and enter, this will commit with the message you typed. In your current state, to just come out without committing, you can do :q instead of the :wq as mentioned above.

Alternatively, you can just do git commit -m '<message>' instead of having git open the editor to type the message.

Note that you can also change the editor and use something you are comfortable with ( like notepad) - How can I set up an editor to work with Git on Windows?

In order to fully avoid floating point issues, the amount whose percent is being calculated and the percent itself need to be converted to integers. Here's how I resolved this:

function calculatePercent(amount, percent) {
    const amountDecimals = getNumberOfDecimals(amount);
    const percentDecimals = getNumberOfDecimals(percent);
    const amountAsInteger = Math.round(amount + `e${amountDecimals}`);
    const percentAsInteger = Math.round(percent + `e${percentDecimals}`);
    const precisionCorrection = `e-${amountDecimals + percentDecimals + 2}`;    // add 2 to scale by an additional 100 since the percentage supplied is 100x the actual multiple (e.g. 35.8% is passed as 35.8, but as a proper multiple is 0.358)

    return Number((amountAsInteger * percentAsInteger) + precisionCorrection);
}

function getNumberOfDecimals(number) {
    const decimals = parseFloat(number).toString().split('.')[1];

    if (decimals) {
        return decimals.length;
    }

    return 0;
}

calculatePercent(20.05, 10); // 2.005

As you can see, I:

1. Count the number of decimals in both the amount and the percent
2. Convert both amount and percent to integers using exponential notation
3. Calculate the exponential notation needed to determine the proper end value
4. Calculate the end value

The usage of exponential notation was inspired by Jack Moore's blog post. I'm sure my syntax could be shorter, but I wanted to be as explicit as possible in my usage of variable names and explaining each step.

<div class="container">
    <div class="row">
        <div class="col-md-12">
            <div class="row">
                <div class="col-md-4">  
                    <a href="">About</a>
                </div>
                <div class="col-md-4">
                    <img src="image.png">
                </div>
                <div class="col-md-4"> 
                    <a href="#myModal1" data-toggle="modal">SHARE</a>
                </div>
            </div>
        </div>
    </div>
</div>

You need to nest the interior columns inside of a row rather than just another column. It offsets the padding caused by the column with negative margins.

A simpler way would be

<div class="container">
   <div class="row">
       <div class="col-md-4">  
          <a href="">About</a>
       </div>
       <div class="col-md-4">
          <img src="image.png">
       </div>
       <div class="col-md-4"> 
           <a href="#myModal1" data-toggle="modal">SHARE</a>
       </div>
    </div>
</div>

I ran into this on Mac as well, and it seems to be related to having an unfortunately similarly named "crypto" module (not sure what that is for) installed alongside of pycrypto via pip.

The fix seems to be removing both crypto and pycrypto with pip:

sudo pip uninstall crypto
sudo pip uninstall pycrypto

and reinstalling pycrypto:

sudo pip install pycrypto

Now it works as expected when I do something like:

from Crypto.Cipher import AES

The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options value as a default.

As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.

Mathematica or Maple will allow you to give as many decimal places as your heart desires.

EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.

On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin (usually 2e-308).

Compare these two analyses.

x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1)  #Should throw an error

x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2)  #ok

In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.

As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr package.

mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")

These are slower and more memory intensive to use than regular (double precision) numeric vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.

C++20 std::format("{}"

https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification claims that the default output format will be the string by default:

auto s6 = std::format("{:6}", true);  // value of s6 is "true  "

and:

The available bool presentation types are:

• none, s: Copies textual representation (true or false, or the locale-specific form) to the output.
• b, B, c, d, o, x, X: Uses integer presentation types with the value static_cast(value).

Related: std::string formatting like sprintf

One other cause may be using lombok.

@Builder - causes to save Collections.emptyList() even if you say .myCollection(new ArrayList());

@Singular - ignores the class level defaults and leaves field null even if the class field was declared as myCollection = new ArrayList()

My 2 cents, just spent 2 hours with the same :)

I usually just do:

try:
    doSomething()
except:
    _ = ""

As of now, it's possible to remove all consecutive duplicate lines with Notepad in-built functionality. Sort the lines first:

Edit > Line Operations > "Sort lines lexicographically",

then

Edit > Line Operations > "Remove Consecutive Duplicate Lines".

The regex solution suggested above didn't remove all duplicate lines for me, but just the consecutive ones as well.

Statement s = cd.createStatement();
ResultSet r = s.executeQuery("SELECT COUNT(*) AS rowcount FROM FieldMaster");
r.next();
int count = r.getInt("rowcount");
r.close();
System.out.println("MyTable has " + count + " row(s).");

Sometimes JDBC does not support following method gives Error like `TYPE_FORWARD_ONLY' use this solution

Sqlite does not support in JDBC.

resultSet.last();
size = resultSet.getRow();
resultSet.beforeFirst();

So at that time use this solution.

Thanks..

I'm not sure I understand your intent perfectly, but perhaps the following would be close to what you want:

select n1.name, n1.author_id, count_1, total_count
  from (select id, name, author_id, count(1) as count_1
          from names
          group by id, name, author_id) n1
inner join (select id, author_id, count(1) as total_count
              from names
              group by id, author_id) n2
  on (n2.id = n1.id and n2.author_id = n1.author_id)

Unfortunately this adds the requirement of grouping the first subquery by id as well as name and author_id, which I don't think was wanted. I'm not sure how to work around that, though, as you need to have id available to join in the second subquery. Perhaps someone else will come up with a better solution.

Share and enjoy.

On my Ubuntu machine, I can see the output at /var/log/syslog.

On a RHEL/CentOS machine, the output is found in /var/log/messages.

This is controlled by the rsyslog service, so if this is disabled for some reason you may need to start it with systemctl start rsyslog.

As noted by others, your syslog() output would be logged by the /var/log/syslog file.
You can see system, user, and other logs at /var/log.

For more details: here's an interesting link.

SELECT last_value, increment_by from "other_schema".id_seq;

for adding a seq to a column where the schema is not public try this.

nextval('"other_schema".id_seq'::regclass)

Set the XML as:

<ToggleButton
    android:id="@+id/flashlightButton"
    style="@style/Button"
    android:layout_above="@+id/buttonStrobeLight"
    android:layout_marginBottom="20dp"
    android:onClick="onToggleClicked"
    android:text="ToggleButton"
    android:textOn="Light ON"
    android:textOff="Light OFF" />

One tweak to all of these answers:

var routes = fs.readdirSync('routes')
      .filter(function(v){
         return (/.js$/).test(v);
      });

Just use a regex to filter via testing each file in the array. It is not recursive, but it will filter out folders that don't end in .js

parent.abc() will only work on same domain due to security purposes. i tried this workaround and mine worked perfectly.

<head>
    <script>
    function abc() {
        alert("sss");
    }

    // window of the iframe
    var innerWindow = document.getElementById('myFrame').contentWindow;
    innerWindow.abc= abc;

    </script>
</head>
<body>
    <iframe id="myFrame">
        <a onclick="abc();" href="#">Click Me</a>
    </iframe>
</body>

Hope this helps. :)

var votevalue = $.map($(this).data('votevalue'), Number);

If you question is something like this: tobeFormattedString = ["a", "b", "c"] Output = "abc"

I found a good choice to be coc.nvim with the python language server.

It takes a bit of effort to set up. I got frustrated with jedi-vim, because it would always freeze vim for a bit when completing. coc.nvim doesn't do it because it's asyncronous, meaning that . It also gives you linting for your code. It supports many other languages and is highly configurable.

The python language server uses jedi so you get the same completion as you would get from jedi.

<context:property-placeholder ... /> is the XML equivalent to the PropertyPlaceholderConfigurer. So, prefer that. The <util:properties/> simply factories a java.util.Properties instance that you can inject.

In Spring 3.1 (not 3.0...) you can do something like this:

@Configuration
@PropertySource("/foo/bar/services.properties")
public class ServiceConfiguration { 

    @Autowired Environment environment; 

    @Bean public javax.sql.DataSource dataSource( ){ 
        String user = this.environment.getProperty("ds.user");
        ...
    } 
}

In Spring 3.0, you can "access" properties defined using the PropertyPlaceHolderConfigurer mechanism using the SpEl annotations:

@Value("${ds.user}") private String user;

If you want to remove the XML all together, simply register the PropertyPlaceholderConfigurer manually using Java configuration. I prefer the 3.1 approach. But, if youre using the Spring 3.0 approach (since 3.1's not GA yet...), you can now define the above XML like this:

@Configuration 
public class MySpring3Configuration {     
        @Bean 
        public static PropertyPlaceholderConfigurer configurer() { 
             PropertyPlaceholderConfigurer ppc = ...
             ppc.setLocations(...);
             return ppc; 
        } 

        @Bean 
        public class DataSource dataSource(
                @Value("${ds.user}") String user, 
                @Value("${ds.pw}") String pw, 
                ...) { 
            DataSource ds = ...
            ds.setUser(user);
            ds.setPassword(pw);                        
            ...
            return ds;
        }
}

Note that the PPC is defined using a static bean definition method. This is required to make sure the bean is registered early, because the PPC is a BeanFactoryPostProcessor - it can influence the registration of the beans themselves in the context, so it necessarily has to be registered before everything else.

A very portable way is to parse the output of this command.

ifconfig | awk '$0 ~ /HWaddr/ { print $5 }'

Provided ifconfig can be run as the current user (usually can) and awk is installed (it often is). This will give you the mac address of the machine.

In casual code I've created lists with millions of elements. I believe that Python's implementation of lists are only bound by the amount of memory on your system.

In addition, the list methods / functions should continue to work despite the size of the list.

If you care about performance, it might be worthwhile to look into a library such as NumPy.

If you use code analysis tools (e.g. FxCop), it will recommend that you mark a method static if that method don't access instance data. The rationale is that there is a performance gain. MSDN: CA1822 - Mark members as static.

It is more of a guideline than a rule, really...

None of these worked for me using 4.1 video.js CDN. This code kills the video playing in a modal when the (.closemodal) is clicked. I had 3 videos. Someone else can refactor.

var myPlayer = videojs("my_video_1");
var myPlayer2 = videojs("my_video_2");
var myPlayer3 = videojs("my_video_3");
$(".closemodal").click(function(){
   myPlayer.pause();
myPlayer2.pause();
myPlayer3.pause();
});
});

as per their Api docs.

There is one more way to use Java

import java.io._

def printToFile(f: java.io.File)(op: java.io.PrintWriter => Unit) 
  {
     val p = new java.io.PrintWriter(f);  
     try { op(p) } 
     finally { p.close() }
  } 

printToFile(new File("C:/TEMP/df.csv")) { p => df.collect().foreach(p.println)}

Since this seems to be the de facto SO question for left outer joins using the method (extension) syntax, I thought I would add an alternative to the currently selected answer that (in my experience at least) has been more commonly what I'm after

// Option 1: Expecting either 0 or 1 matches from the "Right"
// table (Bars in this case):
var qry = Foos.GroupJoin(
          Bars,
          foo => foo.Foo_Id,
          bar => bar.Foo_Id,
          (f,bs) => new { Foo = f, Bar = bs.SingleOrDefault() });

// Option 2: Expecting either 0 or more matches from the "Right" table
// (courtesy of currently selected answer):
var qry = Foos.GroupJoin(
                  Bars, 
                  foo => foo.Foo_Id,
                  bar => bar.Foo_Id,
                  (f,bs) => new { Foo = f, Bars = bs })
              .SelectMany(
                  fooBars => fooBars.Bars.DefaultIfEmpty(),
                  (x,y) => new { Foo = x.Foo, Bar = y });

To display the difference using a simple data set (assuming we're joining on the values themselves):

List<int> tableA = new List<int> { 1, 2, 3 };
List<int?> tableB = new List<int?> { 3, 4, 5 };

// Result using both Option 1 and 2. Option 1 would be a better choice
// if we didn't expect multiple matches in tableB.
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    }

List<int> tableA = new List<int> { 1, 2, 3 };
List<int?> tableB = new List<int?> { 3, 3, 4 };

// Result using Option 1 would be that an exception gets thrown on
// SingleOrDefault(), but if we use FirstOrDefault() instead to illustrate:
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    } // Misleading, we had multiple matches.
                    // Which 3 should get selected (not arbitrarily the first)?.

// Result using Option 2:
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    }
{ A = 3, B = 3    }    

Option 2 is true to the typical left outer join definition, but as I mentioned earlier is often unnecessarily complex depending on the data set.

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

for bootstrap 3 I have the following code in my navbar component

/**
 * Navbar styling.
 */
@mobile:          ~"screen and (max-width: @{screen-xs-max})";
@tablet:          ~"screen and (min-width: @{screen-sm-min})";
@normal:          ~"screen and (min-width: @{screen-md-min})";
@wide:            ~"screen and (min-width: @{screen-lg-min})";
@grid-breakpoint: ~"screen and (min-width: @{grid-float-breakpoint})";

then you can use something like

@media wide { selector: style }

This uses whatever value you have the variables set to.

Escaping allows you to use any arbitrary string as property or variable value. Anything inside ~"anything" or ~'anything' is used as is with no changes except interpolation.

One thing that I haven't seen mentioned yet, is that you can actually make Xcode generate it automatically, when you start a new project. In order to do so, you'll have to start doing some harmless hacking yourself...

Before you begin: Make a backup of "Project Templates", as I predict you'll want to do more than I just mention, once you've discovered it.

Now, go to /Developer/Library/Xcode/Project Templates/Application/Cocoa Application/ Add your .gitignore file there.

That's all. When you create a new "Cocoa Application" project, then the .gitignore file is automatically copied from your project templates.

Beware if you want to edit the templates themselves. Use nano for that; do not use Xcode or TextEdit, they mess up the unicode characters! -Well Xcode also messes up everything else.

Note: There's also a "File Templates", which you should also make a backup of before you start modifying them. Again: Use nano for editing them; not Xcode, nor TextEdit.

Here's one of my own .gitignore files, which you can use for inspiration:

.DS_Store
Icon\15
Icon\r
Icon\n
/*.xcodeproj/*.mode*
/*.xcodeproj/*.pbxuser
/*.xcodeproj/TemplateIcon.icns
/*.xcodeproj/.LSOverride
!/*.xcodeproj/default.*
/*.pbproj/*.mode*
/*.pbproj/*.pbxuser
/*.pbproj/*.perspective*
/build/
*.moved-aside
*~.nib
*~.xib

Note: I use Xcode 2.5 and Xcode 3.1.4 (would prefer 3.1, but it keeps spamming my console)

ChangeDetectorRef.detectChanges() is usually the most focused way of doing this. ApplicationRef.tick() is usually too much of a sledgehammer approach.

To use ChangeDetectorRef.detectChanges(), you'll need this at the top of your component:

import {  ChangeDetectorRef } from '@angular/core';

... then, usually you alias that when you inject it in your constructor like this:

constructor( private cdr: ChangeDetectorRef ) { ... }

Then, in the appropriate place, you call it like this:

this.cdr.detectChanges();

Where you call ChangeDetectorRef.detectChanges() can be highly significant. You need to completely understand the life cycle and exactly how your application is functioning and rendering its components. There's no substitute here for completely doing your homework and making sure you understand the Angular lifecycle inside out. Then, once you understand that, you can use ChangeDetectorRef.detectChanges() appropriately (sometimes it's very easy to understand where you should use it, other times it can be very complex).

String[] errorSoon = { "foo", "bar" };

You may not get "xuxu p1 p2 p3 p4" as it seems. But when you are in PowerShell and you set

PS > set-executionpolicy Unrestricted -scope currentuser

You can run those scripts like this:

./xuxu p1 p2 p3 p4

or

.\xuxu p1 p2 p3 p4

or

./xuxu.ps1 p1 p2 p3 p4

I hope that makes you a bit more comfortable with PowerShell.

With Node and HTML alone you won't be able to achieve what you intend to; it's not like using PHP, where you could do something like <title> <?php echo $custom_title; ?>, without any other stuff installed.

To do what you want using Node, you can either use something that's called a 'templating' engine (like Jade, check this out) or use some HTTP requests in Javascript to get your data from the server and use it to replace parts of the HTML with it.

Both require some extra work; it's not as plug'n'play as PHP when it comes to doing stuff like you want.

Use this

SELECT * 
FROM TableToSearch 
WHERE NOT REGEXP_LIKE(ColumnToSearch, '^-?[0-9]+(\.[0-9]+)?$');

Select the tableview in your storyboard and ensure that the style is set to "Plain", instead of "Grouped". You can find this setting in the attributes Inspector tab.

I was having the same problems with the JVM that App Inventor for Android Blocks Editor uses. It sets the heap at 925m max. This is not enough but I couldn't set it more than about 1200m, depending on various random factors on my machine.

I downloaded Nightly, the beta 64-bit browser from Firefox, and also JAVA 7 64 bit version.

I haven't yet found my new heap limit, but I just opened a JVM with a heap size of 5900m. No problem!

I am running Win 7 64 bit Ultimate on a machine with 24gb RAM.

The correct answer is:

Blah.find({}).sort({date: -1}).execFind(function(err,docs){

});

Yes you can. The default location for script files is data/db

If you put any script there you can call it as

load("myjstest.js")      // or 
load("/data/db/myjstest.js")

This is the complete basic structure for 100% width layout in Bootstrap v3.0.0. You shouldn't wrap your <div class="row"> with container class. Cause container class will take lots of margin and this will not provide you full screen (100% width) layout where bootstrap has removed container-fluid class from their mobile-first version v3.0.0.

So just start writing <div class="row"> without container class and you are ready to go with 100% width layout.

My post might not be a solution, but I can provide an example, where this feature has been implemented.

If you visit the signup page of www.supertorrents.org for the first time from you computer, it's fine. But if you refresh the page or open the page again, it identifies you've previously visited the page. The real beauty comes here - it identifies even if you re-install Windows or other OS.

I read somewhere that they store the CPU ID. Although I couldn't find how do they do it, I seriously doubt it, and they might use MAC Address to do it.

I'll definitely share if I find how to do it.

1 - Your malloc() is wrong.
2 - You are overstepping the bounds of the allocated memory
3 - You should initialize your allocated memory

Here is the program with all the changes needed. I compiled and ran... no errors or warnings.

#include <stdio.h>
#include <stdlib.h> //malloc
#include <math.h>  //sine
#include <string.h>

#define TIME 255
#define HARM 32

int main (void) {

    double sine;
    int tcount = 0;
    int hcount = 0;
    /* allocate some heap memory for the large array of waveform data */
    double *ptr = malloc(sizeof(double) * TIME);
     //memset( ptr, 0x00, sizeof(double) * TIME);  may not always set double to 0
    for( tcount = 0; tcount < TIME; tcount++ )
    {
         ptr[tcount] = 0; 
    }

    tcount = 0;
    if (NULL == ptr) {

                sineRads *= (hcount + 1); //scale frequency by harmonic number

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

See How to create and apply a patch with Git. (From the wording of your question, I assumed that this other repository is for an entirely different codebase. If it's a repository for the same code base, you should add it as a remote as suggested by @CharlesB. Even if it is for another code base, I guess you could still add it as a remote, but you might not want to get the entire branch into your repository...)

Quoting from the Conda blog:

Having been involved in the python world for so long, we are all aware of pip, easy_install, and virtualenv, but these tools did not meet all of our specific requirements. The main problem is that they are focused around Python, neglecting non-Python library dependencies, such as HDF5, MKL, LLVM, etc., which do not have a setup.py in their source code and also do not install files into Python’s site-packages directory.

So Conda is a packaging tool and installer that aims to do more than what pip does; handle library dependencies outside of the Python packages as well as the Python packages themselves. Conda also creates a virtual environment, like virtualenv does.

As such, Conda should be compared to Buildout perhaps, another tool that lets you handle both Python and non-Python installation tasks.

Because Conda introduces a new packaging format, you cannot use pip and Conda interchangeably; pip cannot install the Conda package format. You can use the two tools side by side (by installing pip with conda install pip) but they do not interoperate either.

Since writing this answer, Anaconda has published a new page on Understanding Conda and Pip, which echoes this as well:

This highlights a key difference between conda and pip. Pip installs Python packages whereas conda installs packages which may contain software written in any language. For example, before using pip, a Python interpreter must be installed via a system package manager or by downloading and running an installer. Conda on the other hand can install Python packages as well as the Python interpreter directly.

and further on

Occasionally a package is needed which is not available as a conda package but is available on PyPI and can be installed with pip. In these cases, it makes sense to try to use both conda and pip.

The book "Hello, Android, Introducing Google's Mobile Development Platform" gives a nice explanation of the life cycle of android apps. Luckily they have the particular chapter online as an excerpt. See the graphic on page 39 in http://media.pragprog.com/titles/eband3/concepts.pdf

By the way, this book is highly recommendable for android beginners!

The browser's plugin controls those settings, so you can't force it. However, you can do a simple <a href="whatver.pdf"> instead of <a href="whatever.pdf" target="_blank">.

When I tried Continue For it Failed, I got a compiler error. While doing this, I discovered 'Resume':

For Each I As Item In Items

    If I = x Then
       'Move to next item
       Resume Next
    End If

    'Do something

Next

Note: I am using VBA here.

I've already encountered this problem on people using my in-house tools on new 64 bit machines with Office 2010.

all I had to do was change lines of code like this:

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
    (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

To This:

#If VBA7 Then
    Private Declare PtrSafe Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
        (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#Else
    Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _
        (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
#End If

You will, of course want to make sure that the library you're using is available on both machines, but so far nothing I've used has been a problem.

Note that in the old VB6, PtrSafe isn't even a valid command, so it'll appear in red as though you have a compile error, but it won't actually ever give an error because the compiler will skip the first part of the if block.

Applications using the above code compile and run perfectly on Office 2003, 2007, and 2010 32 and 64 bit.

I created a little javascript tool to style elements on screen size without using media queries or recompiling bootstrap css:

https://github.com/Heras/Responsive-Breakpoints

Just add class responsive-breakpoints to any element, and it will automagically add xs sm md lg xl classes to those elements.

Demo: https://codepen.io/HerasHackwork/pen/rGGNEK

You control how a row or column aligns its children using the mainAxisAlignment and crossAxisAlignment properties. For a row, the main axis runs horizontally and the cross axis runs vertically. For a column, the main axis runs vertically and the cross axis runs horizontally.

 mainAxisAlignment: MainAxisAlignment.center,
 crossAxisAlignment: CrossAxisAlignment.center,

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col

By setting verbose 0, 1 or 2 you just say how do you want to 'see' the training progress for each epoch.

verbose=0 will show you nothing (silent)

verbose=1 will show you an animated progress bar like this:

verbose=2 will just mention the number of epoch like this:

$ rails server -b $IP -p $PORT - that solved the same problem for me

This is what I used for my countdown clock:

</SCRIPT>
<center class="auto-style19" style="height: 31px">
<Font face="blacksmith" size="large"><strong>
<SCRIPT LANGUAGE="JavaScript">
var header = "You have <I><font color=red>" 
+ getDaysUntilICD10() + "</font></I>&nbsp; "
header += "days until ICD-10 starts!"
document.write(header)
</SCRIPT>

The HTML inside of my script worked, though I could not explain why.

Circle Time! :) Easy way of making a circle with a hollow center : use border-radius, give the element a border and no background so you can see through it :

div {_x000D_
    display: inline-block;_x000D_
    margin-left: 5px;_x000D_
    height: 100px;_x000D_
    border-radius: 100%;_x000D_
    width:100px;_x000D_
    border:solid black 2px;_x000D_
}_x000D_
_x000D_
body{_x000D_
    background:url('http://lorempixel.com/output/people-q-c-640-480-1.jpg');_x000D_
    background-size:cover;_x000D_
}

Use Simple HTML

<frameset cols="25%,*">

  <frame src="frame_b.htm">
</frameset>

You can use GLOBIGNORE environment variable in Bash.

Suppose you want to delete all files except php and sql, then you can do the following -

export GLOBIGNORE=*.php:*.sql
rm *
export GLOBIGNORE=

Setting GLOBIGNORE like this ignores php and sql from wildcards used like "ls *" or "rm *". So, using "rm *" after setting the variable will delete only txt and tar.gz file.

Underlying cause:
Content scripts are executed in an "isolated world" environment.

Solution::
To access functions/variables of the page context ("main world") you have to inject the code into the page itself using DOM. Same thing if you want to expose your functions/variables to the page context (in your case it's the state() method).

• Note in case communication with the page script is needed:
  Use DOM CustomEvent handler. Examples: one, two, and three.

• Note in case chrome API is needed in the page script:
  Since chrome.* APIs can't be used in the page script, you have to use them in the content script and send the results to the page script via DOM messaging (see the note above).

Safety warning:
A page may redefine or augment/hook a built-in prototype so your exposed code may fail if the page did it in an incompatible fashion. If you want to make sure your exposed code runs in a safe environment then you should either a) declare your content script with "run_at": "document_start" and use Methods 2-3 not 1, or b) extract the original native built-ins via an empty iframe, example. Note that with document_start you may need to use DOMContentLoaded event inside the exposed code to wait for DOM.

Table of contents

• Method 1: Inject another file
• Method 2: Inject embedded code
• Method 2b: Using a function
• Method 3: Using an inline event
• Dynamic values in the injected code

Method 1: Inject another file

This is the easiest/best method when you have lots of code. Include your actual JS code in a file within your extension, say script.js. Then let your content script be as follows (explained here: Google Chome “Application Shortcut” Custom Javascript):

var s = document.createElement('script');
// TODO: add "script.js" to web_accessible_resources in manifest.json
s.src = chrome.runtime.getURL('script.js');
s.onload = function() {
    this.remove();
};
(document.head || document.documentElement).appendChild(s);

Note: For security reasons, Chrome prevents loading of js files. Your file must be added as a "web_accessible_resources" item (example) :

// manifest.json must include: 
"web_accessible_resources": ["script.js"],

If not, the following error will appear in the console:

Denying load of chrome-extension://[EXTENSIONID]/script.js. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.

Method 2: Inject embedded code

This method is useful when you want to quickly run a small piece of code. (See also: How to disable facebook hotkeys with Chrome extension?).

var actualCode = `// Code here.
// If you want to use a variable, use $ and curly braces.
// For example, to use a fixed random number:
var someFixedRandomValue = ${ Math.random() };
// NOTE: Do not insert unsafe variables in this way, see below
// at "Dynamic values in the injected code"
`;

var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();

Note: template literals are only supported in Chrome 41 and above. If you want the extension to work in Chrome 40-, use:

var actualCode = ['/* Code here. Example: */' + 'alert(0);',
                  '// Beware! This array have to be joined',
                  '// using a newline. Otherwise, missing semicolons',
                  '// or single-line comments (//) will mess up your',
                  '// code ----->'].join('\n');

Method 2b: Using a function

For a big chunk of code, quoting the string is not feasible. Instead of using an array, a function can be used, and stringified:

var actualCode = '(' + function() {
    // All code is executed in a local scope.
    // For example, the following does NOT overwrite the global `alert` method
    var alert = null;
    // To overwrite a global variable, prefix `window`:
    window.alert = null;
} + ')();';
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();

This method works, because the + operator on strings and a function converts all objects to a string. If you intend on using the code more than once, it's wise to create a function to avoid code repetition. An implementation might look like:

function injectScript(func) {
    var actualCode = '(' + func + ')();'
    ...
}
injectScript(function() {
   alert("Injected script");
});

Note: Since the function is serialized, the original scope, and all bound properties are lost!

var scriptToInject = function() {
    console.log(typeof scriptToInject);
};
injectScript(scriptToInject);
// Console output:  "undefined"

Method 3: Using an inline event

Sometimes, you want to run some code immediately, e.g. to run some code before the <head> element is created. This can be done by inserting a <script> tag with textContent (see method 2/2b).

An alternative, but not recommended is to use inline events. It is not recommended because if the page defines a Content Security policy that forbids inline scripts, then inline event listeners are blocked. Inline scripts injected by the extension, on the other hand, still run. If you still want to use inline events, this is how:

var actualCode = '// Some code example \n' + 
                 'console.log(document.documentElement.outerHTML);';

document.documentElement.setAttribute('onreset', actualCode);
document.documentElement.dispatchEvent(new CustomEvent('reset'));
document.documentElement.removeAttribute('onreset');

Note: This method assumes that there are no other global event listeners that handle the reset event. If there is, you can also pick one of the other global events. Just open the JavaScript console (F12), type document.documentElement.on, and pick on of the available events.

Dynamic values in the injected code

Occasionally, you need to pass an arbitrary variable to the injected function. For example:

var GREETING = "Hi, I'm ";
var NAME = "Rob";
var scriptToInject = function() {
    alert(GREETING + NAME);
};

To inject this code, you need to pass the variables as arguments to the anonymous function. Be sure to implement it correctly! The following will not work:

var scriptToInject = function (GREETING, NAME) { ... };
var actualCode = '(' + scriptToInject + ')(' + GREETING + ',' + NAME + ')';
// The previous will work for numbers and booleans, but not strings.
// To see why, have a look at the resulting string:
var actualCode = "(function(GREETING, NAME) {...})(Hi, I'm ,Rob)";
//                                                 ^^^^^^^^ ^^^ No string literals!

The solution is to use JSON.stringify before passing the argument. Example:

var actualCode = '(' + function(greeting, name) { ...
} + ')(' + JSON.stringify(GREETING) + ',' + JSON.stringify(NAME) + ')';

If you have many variables, it's worthwhile to use JSON.stringify once, to improve readability, as follows:

...
} + ')(' + JSON.stringify([arg1, arg2, arg3, arg4]) + ')';

Install Cygwin, which includes Bash among many other GNU and Unix utilities (without whom its unlikely that bash will be very useful anyway).

Another option is MinGW's MSYS which includes bash and a smaller set of the more important utilities such as awk. Personally I would have preferred Cygwin because it includes such heavy lifting tools as Perl and Python which I find I cannot live without, while MSYS skimps on these and assumes you are going to install them yourself.

Updated: If anyone is interested in this answer and is running MS-Windows 10, please note that MS-Windows 10 has a "Windows Subsystem For Linux" feature which - once enabled - allows you to install a user-mode image of Ubuntu and then run Bash on that. This provides 100% compatibility with Ubuntu for debugging and running Bash scripts, but this setup is completely standalone from Windows and you cannot use Bash scripts to interact with Windows features (such as processes and APIs) except for limited access to files through the DrvFS feature.
