If anyone facing similar type of error while adding ShimmerRecyclerView Loader in android , make sure to add maven { url "https://jitpack.io" } under allprojects like below.

    allprojects {
    repositories {
        google()
        jcenter()
        //add it here
        maven { url "https://jitpack.io" }
      }
   }

As of Android Studio version 0.8.14

You should add:

 android {
     packagingOptions { 
         exclude 'META-INF/LICENSE.txt'
         exclude 'META-INF/NOTICE.txt'
         exclude '...'
     }
 }  

to your build.gradle file.

History:

According to comment 14 in this bug: https://issuetracker.google.com/issues/36982149#comment14 this is a bug in v0.7.0 of the Android Gradle plugin, and is due to be fixed soon in 0.7.1.

Here are the notes from that bug about the addition for 0.7.1:

0.7.1 is out with the fix for this.

The DSL to exclude files is:

android {
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }
}

You can add as many exclude statement as you want. The value is the archive path. No wildcard or glob support yet.

Filenames "LICENSE.txt" and "NOTICE.txt" are case sensitive. Please try out with "license.txt" and "notice.txt" as well.

Simply use this, install, run and save current process list

https://www.npmjs.com/package/pm2-windows-startup

By my exp., after restart server, need to logon, in order to trigger the auto startup.

In AngularJS you can redirect your form (on submit) to other page by using window.location.href=''; like below:

postData(email){
    if (email=='undefined') {
      this.Utils.showToast('Invalid Email');
    } else {
      var origin = 'Dubai';
      this.download.postEmail(email, origin).then(data => { 
           ...
      });
      window.location.href = "https://www.thesoftdesign.com/";      
    }
  }

Simply try this:

window.location.href = "https://www.thesoftdesign.com/"; 

After searching a lot I found a solution:

Go to Build-> Build Apk(s).

After creating apk you will see a dialog as below.

Click on locate and install it in your phone

If you are using approach with class-based views and different 'action' attrs i mean

Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.

You can easily handle errors from different forms using overloaded get_context_data method, e.x:

views.py:

class LoginView(FormView):
    form_class = AuthFormEdited
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    ....

    def get_context_data(self, **kwargs):
        context = super(LoginView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = True
        return context

class SignInView(FormView):
    form_class = SignInForm
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(SignInView, self).dispatch(request, *args, **kwargs)

    .....

    def get_context_data(self, **kwargs):
        context = super(SignInView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = False
        return context

template:

<div class="login-form">
<form action="/login/" method="post" role="form">
    {% csrf_token %}
    {% if login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
    .....
    </form>
</div>

<div class="signin-form">
<form action="/registration/" method="post" role="form">
    {% csrf_token %}
    {% if not login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
   ....
  </form>

My solution, using a SwitchCompat and Kotlin. In my situation, i needed to react to a change only if the user triggered it through the UI. In fact, my switch reacts to a LiveData, and this made both setOnClickListener and setOnCheckedChangeListener unusable. setOnClickListener in fact reacts correctly to user interaction, but it's not triggered if the user drags the thumb across the switch. setOnCheckedChangeListener on the other end is triggered also if the switch is toggled programmatically (for example by an observer). Now in my case the switch was present on two fragments, and so onRestoreInstanceState would trigger in some cases the switch with an old value overwriting the correct value.

So, i looked at the code of SwitchCompat, and was able to mimic it's behaviour successfully in distinguishing click and drag and used that to build a custom touchlistener that works as it should. Here we go:

/**
 * This function calls the lambda function passed with the right value of isChecked
 * when the switch is tapped with single click isChecked is relative to the current position so we pass !isChecked
 * when the switch is dragged instead, the position of the thumb centre where the user leaves the
 * thumb is compared to the middle of the switch, and we assume that left means false, right means true
 * (there is no rtl or vertical switch management)
 * The behaviour is extrapolated from the SwitchCompat source code
 */
class SwitchCompatTouchListener(private val v: SwitchCompat, private val lambda: (Boolean)->Unit) :  View.OnTouchListener {
    companion object {
        private const val TOUCH_MODE_IDLE = 0
        private const val TOUCH_MODE_DOWN = 1
        private const val TOUCH_MODE_DRAGGING = 2
    }

    private val vc = ViewConfiguration.get(v.context)
    private val mScaledTouchSlop = vc.scaledTouchSlop
    private var mTouchMode = 0
    private var mTouchX = 0f
    private var mTouchY = 0f

    /**
     * @return true if (x, y) is within the target area of the switch thumb
     * x,y and rect are in view coordinates, 0,0 is top left of the view
     */
    private fun hitThumb(x: Float, y: Float): Boolean {
        val rect = v.thumbDrawable.bounds
        return x >= rect.left && x <= rect.right && y >= rect.top && y <= rect.bottom
    }

    override fun onTouch(view: View, event: MotionEvent): Boolean {
        if (view == v) {
            when (MotionEventCompat.getActionMasked(event)) {
                MotionEvent.ACTION_DOWN -> {
                    val x = event.x
                    val y = event.y
                    if (v.isEnabled && hitThumb(x, y)) {
                        mTouchMode = TOUCH_MODE_DOWN;
                        mTouchX = x;
                        mTouchY = y;
                    }
                }
                MotionEvent.ACTION_MOVE -> {
                    val x = event.x
                    val y = event.y
                    if (mTouchMode == TOUCH_MODE_DOWN &&
                        (abs(x - mTouchX) > mScaledTouchSlop || abs(y - mTouchY) > mScaledTouchSlop)
                    )
                        mTouchMode = TOUCH_MODE_DRAGGING;
                }
                MotionEvent.ACTION_UP,
                MotionEvent.ACTION_CANCEL -> {
                    if (mTouchMode == TOUCH_MODE_DRAGGING) {
                        val r = v.thumbDrawable.bounds
                        if (r.left + r.right < v.width) lambda(false)
                        else lambda(true)
                    } else lambda(!v.isChecked)
                    mTouchMode = TOUCH_MODE_IDLE;
                }
            }
        }
        return v.onTouchEvent(event)
    }
}

How to use it:

the actual touch listener that accepts a lambda with the code to execute:

myswitch.setOnTouchListener(
    SwitchCompatTouchListener(myswitch) {
        // here goes all the code for your callback, in my case
        // i called a service which, when successful, in turn would 
        // update my liveData 
        viewModel.sendCommandToMyService(it) 
    }
)

For the sake of completeness, this is how the observer for the state switchstate (if you have it) looked like:

switchstate.observe(this, Observer {
    myswitch.isChecked = it
})

The reverse of abs is Math.abs(num) * -1.

It's bitwise XOR, Java does not have an exponentiation operator, you would have to use Math.pow() instead.

This is less for @easwee and more for others that might have the same question:

If you do not require support for IE < 10, you can use Flexbox. It's an exciting CSS3 property that unfortunately was implemented in several different versions,; add in vendor prefixes, and getting good cross-browser support suddenly requires quite a few more properties than it should.

With the current, final standard, you would be done with

.container {
    display: flex;
}

.container div {
    flex: 1;
}

.column_center {
    order: 2;
}

That's it. If you want to support older implementations like iOS 6, Safari < 6, Firefox 19 or IE10, this blossoms into

.container {
    display: -webkit-box;      /* OLD - iOS 6-, Safari 3.1-6 */
    display: -moz-box;         /* OLD - Firefox 19- (buggy but mostly works) */
    display: -ms-flexbox;      /* TWEENER - IE 10 */
    display: -webkit-flex;     /* NEW - Chrome */
    display: flex;             /* NEW, Spec - Opera 12.1, Firefox 20+ */
}

.container div {
    -webkit-box-flex: 1;      /* OLD - iOS 6-, Safari 3.1-6 */
    -moz-box-flex: 1;         /* OLD - Firefox 19- */
    -webkit-flex: 1;          /* Chrome */
    -ms-flex: 1;              /* IE 10 */
    flex: 1;                  /* NEW, Spec - Opera 12.1, Firefox 20+ */
}

.column_center {
    -webkit-box-ordinal-group: 2;   /* OLD - iOS 6-, Safari 3.1-6 */
    -moz-box-ordinal-group: 2;      /* OLD - Firefox 19- */
    -ms-flex-order: 2;              /* TWEENER - IE 10 */
    -webkit-order: 2;               /* NEW - Chrome */
    order: 2;                       /* NEW, Spec - Opera 12.1, Firefox 20+ */
}

I couldn't synchronize and change the speed my setIntervals too and I was about to post a question. But I think I've found a way. It should certainly be improved because I'm a beginner. So, I'd gladly read your comments/remarks about this.

<body onload="foo()">
<div id="count1">0</div>
<div id="count2">2nd counter is stopped</div>
<button onclick="speed0()">pause</button>
<button onclick="speedx(1)">normal speed</button>
<button onclick="speedx(2)">speed x2</button>
<button onclick="speedx(4)">speed x4</button>
<button onclick="startTimer2()">Start second timer</button>
</body>
<script>
var count1 = 0,
    count2 = 0,
    greenlight = new Boolean(0), //blocks 2nd counter
    speed = 1000,   //1second
    countingSpeed;
function foo(){
    countingSpeed = setInterval(function(){
        counter1();
        counter2();
    },speed);
}
function counter1(){
    count1++;
    document.getElementById("count1").innerHTML=count1;
}
function counter2(){
    if (greenlight != false) {
        count2++;
        document.getElementById("count2").innerHTML=count2;
    }
}
function startTimer2(){
    //while the button hasn't been clicked, greenlight boolean is false
    //thus, the 2nd timer is blocked
    greenlight = true;
    counter2();
    //counter2() is greenlighted
}

//these functions modify the speed of the counters
function speed0(){
    clearInterval(countingSpeed);
}
function speedx(a){
    clearInterval(countingSpeed);
    speed=1000/a;
    foo();
}
</script>

If you want the counters to begin to increase once the page is loaded, put counter1() and counter2() in foo() before countingSpeed is called. Otherwise, it takes speed milliseconds before execution. EDIT : Shorter answer.

For that single rule you have, there isn't any shorter way to do it. The child combinator is the same in CSS and in Sass/SCSS and there's no alternative to it.

However, if you had multiple rules like this:

#foo > ul > li > ul > li > a:nth-child(3n+1) {
    color: red;
}

#foo > ul > li > ul > li > a:nth-child(3n+2) {
    color: green;
}

#foo > ul > li > ul > li > a:nth-child(3n+3) {
    color: blue;
}

You could condense them to one of the following:

/* Sass */
#foo > ul > li > ul > li
    > a:nth-child(3n+1)
        color: red
    > a:nth-child(3n+2)
        color: green
    > a:nth-child(3n+3)
        color: blue

/* SCSS */
#foo > ul > li > ul > li {
    > a:nth-child(3n+1) { color: red; }
    > a:nth-child(3n+2) { color: green; }
    > a:nth-child(3n+3) { color: blue; }
}

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

If you want to edit some complex javascript I suggest you use JsFiddle. Alternatively, for smaller pieces of javascript you can just run it through your browser URL bar, here's an example:

javascript:alert("hello world");

And, as it was already suggested both Firebug and Chrome developer tools have Javascript console, in which you can type in your javascript to execute. So do Internet Explorer 8+, Opera, Safari and potentially other modern browsers.

$('[data-dismiss=modal]').on('click', function (e) 

{

var $t = $(this),

        target = $t[0].href || $t.data("target") || $t.parents('#myModal') || [];

   $(target)

    .find("input")
       .val('')
       .end()
    .find("input[type=checkbox]")
       .prop("checked", " ")
       .end();



$("span.inerror").html(' ');

$("span.inerror").removeClass("inerror");

document.getElementById("errorDiv1").innerHTML=" ";

})      

This code can be used on close(data-dismiss)of modal.(to clear all fields)

1. Here I have cleared my input fields and my div as id="errorDiv1" which holds all validation errors.

2. With this code I can also clear other validation errors having class as inerror which is specified in span tag with class inerror and which was not possible using document.getElementsByClassName

I use such a function (for data.table):

# Ta funkcja dla obiektu data.table i zmiennej var.name typu factor tworzy dummy variables o nazwach "var.name: (level1)"
factorToDummy <- function(dtable, var.name){
  stopifnot(is.data.table(dtable))
  stopifnot(var.name %in% names(dtable))
  stopifnot(is.factor(dtable[, get(var.name)]))

  dtable[, paste0(var.name,": ",levels(get(var.name)))] -> new.names
  dtable[, (new.names) := transpose(lapply(get(var.name), FUN = function(x){x == levels(get(var.name))})) ]

  cat(paste("\nDodano zmienne dummy: ", paste0(new.names, collapse = ", ")))
}

Usage:

data <- data.table(data)
data[, x:= droplevels(x)]
factorToDummy(data, "x")

If you don't declare a function and it only appears after being called, it is automatically assumed to be int, so in your case, you didn't declare

void my_print (char *);
void my_print2 (char *);

before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *); and int my_print2 (char *); and you can't have two functions with the same prototype except of the return type, so you get the error of conflicting types.

As Brian suggested, declare those two methods before main.

erm it does work? I've just tested it?

Copying Will's comment into an answer, because I found it useful:

var string = "this is a string";
var length = 20;
var trimmedString = string.length > length ? 
                    string.substring(0, length - 3) + "..." : 
                    string;

Thanks Will.

You want the Pillow library, here is how to install it on Python 3:

pip3 install Pillow

If that does not work for you (it should), try normal pip:

Odeds answer is almost complete. Just one thing to add.

1. Escape xml special chars like Emanuele Greco said.
2. Put the password in single quotes like Oded said
3. (this one is new) Escape single ticks with another single tick (ref)

having this password="'; this sould be a valid connection string:

connectionString='Server=dbsrv;User ID=myDbUser;Password='"&&;'

You can set the draggable attribute to false in either the markup or JavaScript code.

// As a jQuery method: $('#myImage').attr('draggable', false);_x000D_
document.getElementById('myImage').setAttribute('draggable', false);

<img id="myImage" src="http://placehold.it/150x150">

You are on the right track. std::sort will use operator< as comparison function by default. So in order to sort your objects, you will either have to overload bool operator<( const T&, const T& ) or provide a functor that does the comparison, much like this:

 struct C {
    int i;
    static bool before( const C& c1, const C& c2 ) { return c1.i < c2.i; }
 };

 bool operator<( const C& c1, const C& c2 ) { return c1.i > c2.i; }

 std::vector<C> values;

 std::sort( values.begin(), values.end() ); // uses operator<
 std::sort( values.begin(), values.end(), C::before );

The advantage of the usage of a functor is that you can use a function with access to the class' private members.

I have found simplest way to create Parcelable class

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

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

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

If you type "AAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGG" this will produce:

The two classes are functionally equivalent, except that System.Timers.Timer has an option to invoke all its timer expiration callbacks through ISynchronizeInvoke by setting SynchronizingObject. Otherwise, both timers invoke expiration callbacks on thread pool threads.

When you drag a System.Timers.Timer onto a Windows Forms design surface, Visual Studio sets SynchronizingObject to the form object, which causes all expiration callbacks to be called on the UI thread.

You need to use list-style-type: to change bullet type/style and the above link has all of the options listed. As others have stated the color is changed using the color property on the ul itself

To create 'black filled' bullets, use 'disc' instead of 'circle',i.e.:

list-style-type:disc

The problem is an issue of semantic meaning (as BoltClock mentions) and visual rendering.

Originally HTML used <b> and <i> for these purposes, entirely stylistic commands, laid down in the semantic environment of the document markup. CSS is an attempt to separate out as far as possible the stylistic elements of the medium. Thus style information such as bold and italics should go in CSS.

<strong> and <em> were introduced to fill the semantic need for text to be marked as more important or stressed. They have default stylistic interpretations akin to bold and italic, but they are not bound to that fate.

1) div id is not reusable and should only be applied to one element of HTML while div class can be added to multiple elements.

2) An id has greater importance if both are applied to the same element and have conflicting styles, the styles of the id will be applied.

3) Style element always refer a div class by putting a . (dot) in front of their names while div id class is referred by putting a # (hash) in front of their names.

4) Example :-

class in <style> declaration - .red-background { background-color: red; }

id in <style> declaration - #blue-background {background-color: blue;}

<div class="red-background" id="blue-background">Hello</div> Here background will be in blue color

I know, this is an old question but I'm trying to explain every step, so it may help others. This is how I add an existing source to git:

1. Create the repo on the git, so you'll have the ssh || https where you're gonna remote add you source code.
2. In your terminal go to the path of your project.
3. Run git init (here you initiate the project as a git one).
4. Run git add * (here you add all the files and folders from you project).
5. Run git commit -m "Initial Commit." (here you commit your files and folders added in step #4; keep in mention that you can't push your changes without committing them).
6. Run git remote add origin https://[email protected]/your_username/project-name.git (here you add a remote project where your source it's gonna be pushed; replace my link with your ssh || https from the step #1).
7. Run git push -u origin master (here you push your source into the git repository).

Note: Those are simple steps for pushing your source into the master branch.

Try this (but please use buttons for such cases if you don't have a valid href value for graceful degradation)

<a href="#" onclick="callmymethod(24); return false;">Call</a>

As stated by Taylor L, you can't just "stop" a thread (by calling a simple method) due to the fact that it could leave your system in an unstable state as the external calling thread may not know what is going on inside your thread.

With this said, the best way to "stop" a thread is to have the thread keep an eye on itself and to have it know and understand when it should stop.

How about another, simpler approach:

require 'fileutils'
FileUtils.cmp(file1, file2)

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

 app.get('/category', function(req, res) {
  var string = query
  res.redirect('/?valid=' + string);
});

in the ejs you can directly use valid:

<% var k = valid %>

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

Why not create an extension method? That's more readable.

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dir, params string[] extensions)
{
    if (extensions == null) 
         throw new ArgumentNullException("extensions");
    IEnumerable<FileInfo> files = Enumerable.Empty<FileInfo>();
    foreach(string ext in extensions)
    {
       files = files.Concat(dir.GetFiles(ext));
    }
    return files;
}

EDIT: a more efficient version:

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dir, params string[] extensions)
{
    if (extensions == null) 
         throw new ArgumentNullException("extensions");
    IEnumerable<FileInfo> files = dir.EnumerateFiles();
    return files.Where(f => extensions.Contains(f.Extension));
}

Usage:

DirectoryInfo dInfo = new DirectoryInfo(@"c:\MyDir");
dInfo.GetFilesByExtensions(".jpg",".exe",".gif");

That error is here to force you to write better code, and be sure to use everything you declare or import. It makes it easier to read code written by other people (you are always sure that all declared variables will be used), and avoid some possible dead code.

But, if you really want to skip this error, you can use the blank identifier (_) :

package main

import (
    "fmt" // imported and not used: "fmt"
)

func main() {
    i := 1 // i declared and not used
}

becomes

package main

import (
    _ "fmt" // no more error
)

func main() {
    i := 1 // no more error
    _ = i
}

As said by kostix in the comments below, you can find the official position of the Go team in the FAQ:

The presence of an unused variable may indicate a bug, while unused imports just slow down compilation. Accumulate enough unused imports in your code tree and things can get very slow. For these reasons, Go allows neither.

The best solution in my opinion is to encapsulate the InputStream in a JSONTokener object. Something like this:

JSONObject jsonObject = new JSONObject(new JSONTokener(inputStream));

A more complete answer would be it is not possible with ftp(at least the ftp program installed on centos 6).

Since you wanted an un-attended process, "pts"'s answer will work fine.

Do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

%40 doesn't appear to work.

[~]# ftp domain.com
ftp: connect: Connection refused
ftp> quit
[~]# ftp some_user%[email protected]
ftp: some_user%[email protected]: Name or service not known
ftp> quit

All I've got is to open the ftp program and use the domain and enter the user when asked. Usually, a password is required anyway, so the interactive nature probably isn't problematic.

Bundler is a Gem manager which provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that are needed.

Gemfile and Gemfile.lock are primary products given by Bundler gem (Bundler itself is a gem).

Gemfile contains your project dependency on gem(s), that you manually mention with version(s) specified, but those gem(s) inturn depends on other gem(s) which is resolved by bundler automatically.

Gemfile.lock contain complete snapshot of all the gem(s) in Gemfile along with there associated dependency.

When you first call bundle install, it will create this Gemfile.lock and uses this file in all subsequent calls to bundle install, which ensures that you have all the dependencies installed and will skip dependency installation.

Same happens when you share your code with different machines

You share your Gemfile.lock along with Gemfile, when you run bundle install on other machine it will refer to your Gemfile.lock and skip dependency resolution step, instead it will install all of the same dependent gem(s) that you used on the original machine, which maintains consistency across multiple machines

Why do we need to maintain consistency along multiple machines ?

• Running different versions on different machines could lead to broken code

• Suppose, your app used the version 1.5.3 and it works 14 months ago
  without any problems, and you try to install on different machine
  without Gemfile.lock now you get the version 1.5.8. Maybe it's broken with the latest version of some gem(s) and your application will
  fail. Maintaining consistency is of utmost importance (preferred
  practice).

It is also possible to update gem(s) in Gemfile.lock by using bundle update.

This is based on the concept of conservative updating

Make it serializable

// example error
let err = new Error('I errored')

// one liner converting Error into regular object that can be stringified
err = Object.getOwnPropertyNames(err).reduce((acc, key) => { acc[key] = err[key]; return acc; }, {})

If you want to send this object from child process, worker or though the network there's no need to stringify. It will be automatically stringified and parsed like any other normal object

It is standard matplotlib.pyplot:

...
import matplotlib.pyplot as plt
plt.ylim(10, 40)

Or simpler, as mwaskom comments below:

ax.set(ylim=(10, 40))

AppDomain.UnhandledException Event

This event provides notification of uncaught exceptions. It allows the application to log information about the exception before the system default handler reports the exception to the user and terminates the application.

   public App()
   {
      AppDomain currentDomain = AppDomain.CurrentDomain;
      currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);    
   }

   static void MyHandler(object sender, UnhandledExceptionEventArgs args) 
   {
      Exception e = (Exception) args.ExceptionObject;
      Console.WriteLine("MyHandler caught : " + e.Message);
      Console.WriteLine("Runtime terminating: {0}", args.IsTerminating);
   }

If the UnhandledException event is handled in the default application domain, it is raised there for any unhandled exception in any thread, no matter what application domain the thread started in. If the thread started in an application domain that has an event handler for UnhandledException, the event is raised in that application domain. If that application domain is not the default application domain, and there is also an event handler in the default application domain, the event is raised in both application domains.

For example, suppose a thread starts in application domain "AD1", calls a method in application domain "AD2", and from there calls a method in application domain "AD3", where it throws an exception. The first application domain in which the UnhandledException event can be raised is "AD1". If that application domain is not the default application domain, the event can also be raised in the default application domain.

Convert your JSON object to JSON String using

JSON.stringify({"name":"testName"})

or manually. @RequestBody expecting json string instead of json object.

Note:stringify function having issue with some IE version, firefox it will work

verify the syntax of your ajax request for POST request. processData:false property is required in ajax request

$.ajax({ 
    url:urlName,
    type:"POST", 
    contentType: "application/json; charset=utf-8",
    data: jsonString, //Stringified Json Object
    async: false,    //Cross-domain requests and dataType: "jsonp" requests do not support synchronous operation
    cache: false,    //This will force requested pages not to be cached by the browser  
     processData:false, //To avoid making query String instead of JSON
     success: function(resposeJsonObject){
        // Success Action
    }
});

Controller

@RequestMapping(value = urlPattern , method = RequestMethod.POST)

public @ResponseBody Test addNewWorker(@RequestBody Test jsonString) {

    //do business logic
    return test;
}

@RequestBody -Covert Json object to java

@ResponseBody - convert Java object to json

Well, I'm not sure if my solution is best practice. Using the NotificationBuilder my code looks like that:

private void showNotification() {
    Intent notificationIntent = new Intent(this, MainActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(
                this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, builder.build());
    }

Manifest:

    <activity
        android:name=".MainActivity"
        android:launchMode="singleInstance"
    </activity>

and here the Service:

    <service
        android:name=".services.ProtectionService"
        android:launchMode="singleTask">
    </service>

I don't know if there really is a singleTask at Service but this works properly at my application...

I was using firefox and some reason, it was not taking the click command though from past 2months it was working. My feeling was to make use of sendKeys and this page solved the problem. Now I am using sendKeys(Keys.Enter)

The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203

The international numbering plan is based on the ITU E.164 numbering plan. I guess that's the starting point to your regular expression.

I'll update this if I get around to create a regular expression based on the ITU E.164 numbering.

As others have already pointed out, using lodash or underscore is probably the best solution. But if you do not need those libraries for anything else, you can probably use something like this:

  function deepClone(obj) {

    // return value is input is not an Object or Array.
    if (typeof(obj) !== 'object' || obj === null) {
      return obj;    
    }

    let clone;

    if(Array.isArray(obj)) {
      clone = obj.slice();  // unlink Array reference.
    } else {
      clone = Object.assign({}, obj); // Unlink Object reference.
    }

    let keys = Object.keys(clone);

    for (let i=0; i<keys.length; i++) {
      clone[keys[i]] = deepClone(clone[keys[i]]); // recursively unlink reference to nested objects.
    }

    return clone; // return unlinked clone.

  }

That's what we decided to do.

This should work:

<div style="text-align:center;">
  <table style="margin: 0 auto;">
    <!-- table markup here. -->
  </table>
</div>

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

You can try this:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});

Easiest way to find duplicate values in a JavaScript array

Both answers provide solutions a bit more complex, as they need to be. Say the payment was created on January 6, 2013. And we want to know the difference between this date and today.

sqlite> SELECT julianday() - julianday('2013-01-06');
34.7978485878557 

The difference is 34 days. We can use julianday('now') for better clarity. In other words, we do not need to put date() or datetime() functions as parameters to julianday() function.

If you want to automatically stash your changes and unstash them for every rebase, you can do this:

git config --global rebase.autoStash true

SingleOrDefault() is what you need

cheers

A JavaScript accordion does the trick.

This fiddle by W3Schools makes a simple task even more simple using nothing but javascript, which i partially reproduce below.

<head>
<style>
button.accordion {
    background-color: #eee;
    color: #444;
    font-size: 15px;
    cursor: pointer;
}

button.accordion.active, button.accordion:hover {
    background-color: #ddd; 
}

div.panel {
    padding: 0 18px;
    display: none;
    background-color: white;
}

div.panel.show {
    display: block;
}
</style>
</head><body>
<script>
var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
    this.classList.toggle("active");
    this.nextElementSibling.classList.toggle("show");
  }
}
</script>
...
<button class="accordion">Section 1</button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
</div>
...
<button class="accordion">Table</button>
<div class="panel">
  <p><table name="detail_table">...</table></p>
</div>
...
<button class="accordion"><table name="button_table">...</table></button>
<div class="panel">
  <p>Lorem ipsum dolor sit amet</p>
  <table name="detail_table">...</table>
  <img src=...></img>
</div>
...
</body></html>

if using php, don't forget to convert " to '. You can also use tables of data inside the button and it will still work.

Under browsers supporting js 1.8:

[i for(i in obj)]

The timeout you specify here needs to be shorter than the default timeout.

The default timeout is 5000 and the framework by default is jasmine in case of jest. You can specify the timeout inside the test by adding

jest.setTimeout(30000);

But this would be specific to the test. Or you can set up the configuration file for the framework.

Configuring Jest

// jest.config.js
module.exports = {
  // setupTestFrameworkScriptFile has been deprecated in
  // favor of setupFilesAfterEnv in jest 24
  setupFilesAfterEnv: ['./jest.setup.js']
}

// jest.setup.js
jest.setTimeout(30000)

See also these threads:

setTimeout per test #5055

Make jasmine.DEFAULT_TIMEOUT_INTERVAL configurable #652

P.S.: The misspelling setupFilesAfterEnv (i.e. setupFileAfterEnv) will also throw the same error.

Try this: char c=S.nextLine().charAt(0);

To add a WHERE clause inside an INSERT statement simply;

INSERT INTO table_name (column1,column2,column3)
SELECT column1, column2, column3 FROM  table_name
WHERE column1 = 'some_value'

This is better method how insert item to array on some position.

function arrayInsert($array, $item, $position)
{
    $begin = array_slice($array, 0, $position);
    array_push($begin, $item);
    $end = array_slice($array, $position);
    $resultArray = array_merge($begin, $end);
    return $resultArray;
}

As far as I know, iterate and instantiate is the only way to do this. Something like (for others potential help, since I'm sure you know how to do this):

List<Integer> oldList = ...
/* Specify the size of the list up front to prevent resizing. */
List<String> newList = new ArrayList<>(oldList.size());
for (Integer myInt : oldList) { 
  newList.add(String.valueOf(myInt)); 
}

When using NOT IN you should ensure that none of the values are NULL:

SELECT mac, creation_date 
FROM logs 
WHERE logs_type_id=11
AND mac NOT IN (
    SELECT mac
    FROM consols
    WHERE mac IS NOT NULL -- add this
)

Task: Given two int arrays array1 and array2 of the same length, zip should return an array that's twice as long, in which the elements of array1 and array2 are interleaved. That is, element #0 of the result array is array1[0], element #1 is array2[0], element #2 is array1[1], element #3 is array2[1], and so on.

public static int [] zip(int [ ] array1, int [] array2) {
//make sure both arrays have same length
if (array1.length != array2.length) {
    throw new IllegalArgumentException("Unequal array lengths - zip not possible");
}

int [] zippedArray = new int [array1.length+ array2.length]; 
int idx_1 = 0;
int idx_2 = 0;

//for each element of first array, add to new array if index of new array is even

for (int i=0; i < zippedArray.length; i+=2){
    zippedArray[i]= array1[idx_1++];
}
for (int i=1; i < zippedArray.length; i+=2){
    zippedArray[i]= array2[idx_2++];
}

//check contents of new array       
for (int item: zippedArray){
    System.out.print(item + " ");
}

return zippedArray;

}

here's another solution for Python3:

import csv
with open(filename, "r") as csvfile:
    datareader = csv.reader(csvfile)
    count = 0
    for row in datareader:
        if row[3] in ("column header", criterion):
            doSomething(row)
            count += 1
        elif count > 2:
            break

here datareader is a generator function.

To include the direction along with the orderBy function:

ng-repeat="card in cards | orderBy:myOrderbyFunction():defaultSortDirection"

where

defaultSortDirection = 0; // 0 = Ascending, 1 = Descending

Your listener.ora is misconfigured. There is no orcl service.

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

I had the same problem as the title of this question, so incase anyone else googles upon this question and wants to start MySql in 'skip-grant-tables' mode on Windows, here is what I did.

Stop the MySQL service through Administrator tools, Services.

Modify the my.ini configuration file (assuming default paths)

C:\Program Files\MySQL\MySQL Server 5.5\my.ini

or for MySQL version >= 5.6

C:\ProgramData\MySQL\MySQL Server 5.6\my.ini 

In the SERVER SECTION, under [mysqld], add the following line:

skip-grant-tables

so that you have

# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.
#
[mysqld]

skip-grant-tables

Start the service again and you should be able to log into your database without a password.

I don't like having to change my signature to use the HttpCreateResponse type, so I came up with a little bit of an extended solution to hide that.

public class HttpActionResult : IHttpActionResult
{
    public HttpActionResult(HttpRequestMessage request) : this(request, HttpStatusCode.OK)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code) : this(request, code, null)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code, object result)
    {
        Request = request;
        Code = code;
        Result = result;
    }

    public HttpRequestMessage Request { get; }
    public HttpStatusCode Code { get; }
    public object Result { get; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        return Task.FromResult(Request.CreateResponse(Code, Result));
    }
}

You can then add a method to your ApiController (or better your base controller) like this:

protected IHttpActionResult CustomResult(HttpStatusCode code, object data) 
{
    // Request here is the property on the controller.
    return new HttpActionResult(Request, code, data);
}

Then you can return it just like any of the built in methods:

[HttpPost]
public IHttpActionResult Post(Model model)
{
    return model.Id == 1 ?
                Ok() :
                CustomResult(HttpStatusCode.NotAcceptable, new { 
                    data = model, 
                    error = "The ID needs to be 1." 
                });
}

It's worth to mention that using concerns is considered bad idea by many.

1. like this guy
2. and this one

Some reasons:

1. There is some dark magic happening behind the scenes - Concern is patching include method, there is a whole dependency handling system - way too much complexity for something that's trivial good old Ruby mixin pattern.
2. Your classes are no less dry. If you stuff 50 public methods in various modules and include them, your class still has 50 public methods, it's just that you hide that code smell, sort of put your garbage in the drawers.
3. Codebase is actually harder to navigate with all those concerns around.
4. Are you sure all members of your team have same understanding what should really substitute concern?

Concerns are easy way to shoot yourself in the leg, be careful with them.

I second that.

Dex2jar will generate a WORKING jar, which you can add as your project source, with the xmls you got from apktool.

However, JDGUI generates .java files which have ,more often than not, errors.

It has got something to do with code obfuscation I guess.

An alternative way can be this: - recommended as using just one expression -

case when address.country <> '' then address.country
else 'United States'
end as country

Note: Result of checking null by <> operator will return false.
And as documented: NULLIF is equivalent to a searched CASE expression
and COALESCE expression is a syntactic shortcut for the CASE expression.
So, combination of those are using two time of case expression.

There are several situations that will give you this particular error. In the case of the OP there was a value defined explicitly as a string. So I have to assume that maybe this came from a dropdown, or web service or raw JSON string.

In that case a simple cast <Fruit> fruitString or fruitString as Fruit is the only solution (see other answers). You wouldn't ever be able to improve on this at compile time. [Edit: See my other answer about <const>] !

However it's very easy to run into this same error when using constants in your code that aren't ever intended to be of type string. My answer focuses on that second scenario:

First of all: Why are 'magic' string constants often better than an enum?

• I like the way a string constant looks vs. an enum - it's compact and 'javascripty'
• Makes more sense if the component you're using already uses string constants.
• Having to import an 'enum type' just to get an enumeration value can be troublesome in itself
• Whatever I do I want it to be compile safe so if I add remove a valid value from the union type, or mistype it then it MUST give a compile error.

Fortunately when you define:

export type FieldErrorType = 'none' | 'missing' | 'invalid'

...you're actually defining a union of types where 'missing' is actually a type!

I often run into the 'not assignable' error if I have a string like 'banana' in my typescript and the compiler thinks I meant it as a string, whereas I really wanted it to be of type banana. How smart the compiler is able to be will depend on the structure of your code.

Here's an example of when I got this error today:

// this gives me the error 'string is not assignable to type FieldErrorType'
fieldErrors: [ { fieldName: 'number', error: 'invalid' } ]

As soon as I found out that 'invalid' or 'banana' could be either a type or a string I realized I could just assert a string into that type. Essentially cast it to itself, and tell the compiler no I don't want this to be a string!

// so this gives no error, and I don't need to import the union type too
fieldErrors: [ { fieldName: 'number', error: <'invalid'> 'invalid' } ]

So what's wrong with just 'casting' to FieldErrorType (or Fruit)

// why not do this?
fieldErrors: [ { fieldName: 'number', error: <FieldErrorType> 'invalid' } ]

It's not compile time safe:

 <FieldErrorType> 'invalidddd';  // COMPILER ALLOWS THIS - NOT GOOD!
 <FieldErrorType> 'dog';         // COMPILER ALLOWS THIS - NOT GOOD!
 'dog' as FieldErrorType;        // COMPILER ALLOWS THIS - NOT GOOD!

Why? This is typescript so <FieldErrorType> is an assertion and you are telling the compiler a dog is a FieldErrorType! And the compiler will allow it!

BUT if you do the following, then the compiler will convert the string to a type

 <'invalid'> 'invalid';     // THIS IS OK  - GOOD
 <'banana'> 'banana';       // THIS IS OK  - GOOD
 <'invalid'> 'invalidddd';  // ERROR       - GOOD
 <'dog'> 'dog';             // ERROR       - GOOD

Just watch out for stupid typos like this:

 <'banana'> 'banan';    // PROBABLY WILL BECOME RUNTIME ERROR - YOUR OWN FAULT!

Another way to solve the problem is by casting the parent object:

My definitions were as follows:

export type FieldName = 'number' | 'expirationDate' | 'cvv'; export type FieldError = 'none' | 'missing' | 'invalid'; export type FieldErrorType = { field: FieldName, error: FieldError };

Let's say we get an error with this (the string not assignable error):

  fieldErrors: [ { field: 'number', error: 'invalid' } ]

We can 'assert' the whole object as a FieldErrorType like this:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'invalid' } ]

Then we avoid having to do <'invalid'> 'invalid'.

But what about typos? Doesn't <FieldErrorType> just assert whatever is on the right to be of that type. Not in this case - fortunately the compiler WILL complain if you do this, because it's clever enough to know it's impossible:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'dog' } ]

or you can use the following to compile the all java source files in current directory..

javac *.java

If you have an arraylist of String called 'foo', you can easily append (add) it to another ArrayList, 'list', using the following method:

ArrayList<String> list = new ArrayList<String>();
list.addAll(foo);

that way you don't even need to loop through anything.

You can search for column in all tables in database using:

SELECT so.name 
FROM sysobjects so
INNER JOIN syscolumns sc ON so.id = sc.id 
WHERE sc.name = 'YOUR_COLUMN_NAME'

Copy xampp_start.exe from your XAMPP install directory to C:\Users\YOUR USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.

Replace YOUR USERNAME with your username.

the best way is to change your route. The default route (defined in your App_Start) sets /Home/Index

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters*
        new { controller = "Home", action = "Index", 
        id = UrlParameter.Optional }
);

as the default landing page. You can change that to be any route you wish.

routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters*
        new { controller = "Sales", action = "ProjectionReport", 
        id = UrlParameter.Optional }
);

Just for fun, another approach would be to just leave the paging and horizontal scrolling set, add a method that changes the order of the array items to convert from 'top to bottom, left to right' to visually 'left to right, top to bottom' and fill the in-between cells with empty hidden cells to make the spacing right. In case of 7 items in a grid of 9, this would go like this:

[1][4][7]
[2][5][ ]
[3][6][ ]

should become

[1][2][3]
[4][5][6]
[7][ ][ ]

so 1=1, 2=4, 3=7 etc. and 6=empty. You can reorder them by calculating the total number of rows and columns, then calculate the row and column number for each cell, change the row for the column and vice versa and then you have the new indexes. When the cell doesn't have a value corresponding to the image you can return an empty cell and set cell.hidden = YES; to it.

It works quite well in a soundboard app I built, so if anyone would like working code I'll add it. Only little code is required to make this trick work, it sounds harder than it is!

Update

I doubt this is the best solution, but by request here's working code:

- (void)viewDidLoad {
    // Fill an `NSArray` with items in normal order
    items = [NSMutableArray arrayWithObjects:
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 1", @"label", @"Some value 1", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 2", @"label", @"Some value 2", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 3", @"label", @"Some value 3", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 4", @"label", @"Some value 4", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 5", @"label", @"Some value 5", @"value", nil],
              nil
              ];

    // Calculate number of rows and columns based on width and height of the `UICollectionView` and individual cells (you might have to add margins to the equation based on your setup!)
    CGFloat w = myCollectionView.frame.size.width;
    CGFloat h = myCollectionView.frame.size.height;
    rows = floor(h / cellHeight);
    columns = floor(w / cellWidth);
}

// Calculate number of sections
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return ceil((float)items.count / (float)(rows * columns));
}

// Every section has to have every cell filled, as we need to add empty cells as well to correct the spacing
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return rows*columns;
}

// And now the most important one
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier@"myIdentifier" forIndexPath:indexPath];

    // Convert rows and columns
    int row = indexPath.row % rows;
    int col = floor(indexPath.row / rows);
    // Calculate the new index in the `NSArray`
    int newIndex = ((int)indexPath.section * rows * columns) + col + row * columns;

    // If the newIndex is within the range of the items array we show the cell, if not we hide it
    if(newIndex < items.count) {
        NSDictionary *item = [items objectAtIndex:newIndex];
        cell.label.text = [item objectForKey:@"label"];
        cell.hidden = NO;
    } else {
        cell.hidden = YES;
    }

    return cell;
}

If you'd like to use the didSelectItemAtIndexPath method you have to use the same conversion that is used in cellForItemAtIndexPath to get the corresponding item. If you have cell margins you need to add them to the rows and columns calculation, as those have to be correct in order for this to work.

The option provided by"praveenak" can also be applied to any other jar files with source file provided. For example, for JavaFx, we right click jfxrt.jar, select "Properties" and enter jdk1.8.0_05/javafx-src.zip for "Path" under External location.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this:

 CPMSifDlg::EncodeAndSend(/*...*/);  //wrong - EncodeAndSend is not static

It should rather be called as:

 CPMSifDlg dlg; //create instance, assuming it has default constructor!
 dlg.EncodeAndSend(/*...*/);   //correct 

Actually The documentation shows that you can use XMLHttpRequest().send() to simply send multiform data in case jquery sucks

Truncate table is faster than delete * from XXX. Delete is slow because it works one row at a time. There are a few situations where truncate doesn't work, which you can read about on MSDN.

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

The answers provided (at the time of this post) are link only answers so I thought I would summarize the links into an answer and what I will be using.

When working to create Cross Browser Favicons (including touch icons) there are several things to consider.

The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:

<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon" for IE to recognize the icon it needs the word shortcut which is not standard. Also we wrap the .ico favicon in a IE conditional comment because Chrome and Safari will use the .ico file if it is present, despite other options available, not what we would like.

The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.

For the rest of the browsers we are going to use the standard way to cite a favicon:

<link rel="icon" href="path/to/favicon.png">

This icon should be 196x196 pixels in size to cover all devices that may use this icon.

To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:

<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

Using rel="apple-touch-icon-precomposed" will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon". This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed".

As a note: Chrome for Android states:

The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).

Custom Tiles for IE 11+ on Windows 8.1+

IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.

Microsoft recommends creating a few tiles at the following size:

Small: 128 x 128

Medium: 270 x 270

Wide: 558 x 270

Large: 558 x 558

These should be transparent images as we will define a color background next.

Once these images are created you should create an xml file called browserconfig.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
  <msapplication>
    <tile>
      <square70x70logo src="images/smalltile.png"/>
      <square150x150logo src="images/mediumtile.png"/>
      <wide310x150logo src="images/widetile.png"/>
      <square310x310logo src="images/largetile.png"/>
      <TileColor>#009900</TileColor>
    </tile>
  </msapplication>
</browserconfig>

Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head:

<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />

For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.

Putting it all together:

To put it all together the above code would look like this:

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">

Windows Phone Live Tiles

If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:

Here are detailed instructions from Microsoft but here is a synopsis:

Step 1

Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.

Step 2

Add a hidden overlay of this image. Here is example code from Microsoft:

<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
  <img src="customtile.png" width="320" height="320" />
  <div style='margin-top: 40px'>
     Add text/graphic asking user to pin to start using the menu...
  </div>
</div>

Step 3

You then can add thew following line to add a pin to start link:

<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>

Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.

Step 4

Next you add some JS to toggle the overlay visibility

<script>
function ToggleTileOverlay() {
 var newVisibility =     (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
 document.getElementById('TileOverlay').style.visibility =    newVisibility;
}
</script>

Note on Sizes

I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

Or you could have done this:

select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') from dual

This returns a NUMBER of whole days:

SQL> create view v as 
  2  select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') diff 
  3  from dual;

View created.

SQL> select * from v;

      DIFF
----------
        29

SQL> desc v
 Name                   Null?    Type

 DIFF                            NUMBER(38)

by using latitude and longitude get time zone of current location below code worked for me

try{
    timezoneurl = timezoneurl+"location=22.7260783,75.8781553&timestamp=1331161200";                    
    // timezoneurl = timezoneurl+"location="+lat+","+lng+"&timestamp=1331161200";

    URL url = new URL(timezoneurl);                
    // Creating an http connection to communicate with url 
    urlConnection = (HttpURLConnection) url.openConnection(); 

    // Connecting to url 
    urlConnection.connect();                

    // Reading data from url 
    iStream = urlConnection.getInputStream();

    BufferedReader br = new BufferedReader(new InputStreamReader(iStream));

    StringBuffer sb  = new StringBuffer();
    String line = "";
    while( ( line = br.readLine())  != null){
        sb.append(line);

I found this to be the simplest approach for Django 1.3:

1. views.py

   from local_settings import BASE_URL
   
   def root(request):
       return render_to_response('hero.html', {'BASE_URL': BASE_URL})
   

2. hero.html

   var BASE_URL = '{{ JS_BASE_URL }}';
   

Let's pretend you want to live in the immutable world and do NOT want to modify the original but want to create a new dict that is the result of adding a new key to the original.

In Python 3.5+ you can do:

params = {'a': 1, 'b': 2}
new_params = {**params, **{'c': 3}}

The Python 2 equivalent is:

params = {'a': 1, 'b': 2}
new_params = dict(params, **{'c': 3})

After either of these:

params is still equal to {'a': 1, 'b': 2}

and

new_params is equal to {'a': 1, 'b': 2, 'c': 3}

There will be times when you don't want to modify the original (you only want the result of adding to the original). I find this a refreshing alternative to the following:

params = {'a': 1, 'b': 2}
new_params = params.copy()
new_params['c'] = 3

or

params = {'a': 1, 'b': 2}
new_params = params.copy()
new_params.update({'c': 3})

Be Careful, Follow these steps and save your time

1. Right Click on your Project Explorer.

2. Select New-> Project -> Android Application Project from Existing Code

3. Browse upto this path only - "C:\Users**your path**\Local\Android\android-sdk\extras\google\google_play_services"

4. Be careful brose only upto - google_play_services and not upto google_play_services_lib

5. And this way you are able to import the google play service lib.

Let me know if you have any queries regarding the same.

This regex work for me (was using in Angular 8) :

([a-zA-Z',.-]+( [a-zA-Z',.-]+)*){2,30}

It will be invalid if there is:-

1. Any whitespace start or end of the name
2. Got symbols e.g. @
3. Less than 2 or more than 30

Example invalid First Name (whitespace)

Example valid First Name :

Due to its folder nesting Windows can’t delete the folder as its name is too long. To solve this, install RimRaf:

npm install rimraf -g

You could create a class that extends the Tkinter Button class, that will be specialised to close your window by associating the destroy method to its command attribute:

from tkinter import *

class quitButton(Button):
    def __init__(self, parent):
        Button.__init__(self, parent)
        self['text'] = 'Good Bye'
        # Command to close the window (the destory method)
        self['command'] = parent.destroy
        self.pack(side=BOTTOM)

root = Tk()
quitButton(root)
mainloop()

This is the output:

And the reason why your code did not work before:

def close_window (): 
    # root.destroy()
    window.destroy()

I have a slight feeling you might got the root from some other place, since you did window = tk().

When you call the destroy on the window in the Tkinter means destroying the whole application, as your window (root window) is the main window for the application. IMHO, I think you should change your window to root.

from tkinter import *

def close_window():
    root.destroy()  # destroying the main window

root = Tk()
frame = Frame(root)
frame.pack()

button = Button(frame)
button['text'] ="Good-bye."
button['command'] = close_window
button.pack()

mainloop()

Yes, it creates only references, which are set to their default value null. That is why you get a NullPointerException You need to create objects separately and assign the reference. There are 3 steps to create arrays in Java -

Declaration – In this step, we specify the data type and the dimensions of the array that we are going to create. But remember, we don't mention the sizes of dimensions yet. They are left empty.

Instantiation – In this step, we create the array, or allocate memory for the array, using the new keyword. It is in this step that we mention the sizes of the array dimensions.

Initialization – The array is always initialized to the data type’s default value. But we can make our own initializations.

Declaring Arrays In Java

This is how we declare a one-dimensional array in Java –

int[] array;
int array[];

Oracle recommends that you use the former syntax for declaring arrays. Here are some other examples of legal declarations –

// One Dimensional Arrays
int[] intArray;             // Good
double[] doubleArray;

// One Dimensional Arrays
byte byteArray[];           // Ugly!
long longArray[];

// Two Dimensional Arrays
int[][] int2DArray;         // Good
double[][] double2DArray;

// Two Dimensional Arrays
byte[] byte2DArray[];       // Ugly
long[] long2DArray[];

And these are some examples of illegal declarations –

int[5] intArray;       // Don't mention size!
double{} doubleArray;  // Square Brackets please!

Instantiation

This is how we “instantiate”, or allocate memory for an array –

int[] array = new int[5];

When the JVM encounters the new keyword, it understands that it must allocate memory for something. And by specifying int[5], we mean that we want an array of ints, of size 5. So, the JVM creates the memory and assigns the reference of the newly allocated memory to array which a “reference” of type int[]

Initialization

Using a Loop – Using a for loop to initialize elements of an array is the most common way to get the array going. There’s no need to run a for loop if you are going to assign the default value itself, because JVM does it for you.

All in One..! – We can Declare, Instantiate and Initialize our array in one go. Here’s the syntax –

int[] arr = {1, 2, 3, 4, 5};

Here, we don’t mention the size, because JVM can see that we are giving 5 values.

So, until we instantiate the references remain null. I hope my answer has helped you..! :)

I had a similar problem, trying to add a background image with inline css. No need to specify the images folder due to the way asset sync works.

This worked for me:

background-image: url('/assets/image.jpg');

1. Navigate to your XAMPP directory, you will find a folder called apache, open it, then copy its path, my path is "D:\Hacking Tools 2\Programs\XAMPP V2\apache"
2. Open up apache\conf\httpd.conf with any text editor
3. Scroll down until line 30-40
4. You will find a code like this: ServerRoot "xampp\apache"
5. Now, change it to be the apache directory, as I said in Step #1, my path is "D:\Hacking Tools 2\Programs\XAMPP V2\apache", so, my code will be ServerRoot "D:\Hacking Tools 2\Programs\XAMPP V2\apache"
6. It should look somehow like this: ServerRoot "D:\XAMPP\apache"
7. Now go back to the XAMPP main directory and run xampp_start.exe

It worked for me, if it doesn't work for you, just comment with the error value after opening the xampp_start.exe

What I needed: A document number with a fixed number of integers that would also act like an AutoField.

My searches took me all over incl. this page.

Finally I did something like this:

I created a table with a DocuNumber field as an IntegerField with foll. attributes:

• max_length=6
• primary_key=True
• unique=True
• default=100000

The max_length value anything as required (and thus the corresponding default= value).

A warning is issued while creating the said model, which I could ignore.

Afterwards, created a document (dummy) whence as expected, the document had an integer field value of 100000.

Afterwards changed the model key field as:

• Changed the field type as: AutoField
• Got rid of the max_length And defaultattributes
• Retained the primary_key = True attribute

The next (desired document) created had the value as 100001 with subsequent numbers getting incremented by 1.

So far so good.

Sure you can with reflection. Here is the code to grab the properties off of a given type.

var info = typeof(SomeType).GetProperties();

If you can give more info on what you're comparing about the properties we can get together a basic diffing algorithmn. This code for intstance will diff on names

public bool AreDifferent(Type t1, Type t2) {
  var list1 = t1.GetProperties().OrderBy(x => x.Name).Select(x => x.Name);
  var list2 = t2.GetProperties().OrderBy(x => x.Name).Select(x => x.Name);
  return list1.SequenceEqual(list2);
}

I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:

 Sub FindSomeCells(strSearchQuery As String)   

    Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
    FindWhat = strSearchQuery
    Set FoundCells = FindAll(SearchRange:=SearchRange, _
                            FindWhat:=FindWhat, _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByColumns, _
                            MatchCase:=False, _
                            BeginsWith:=vbNullString, _
                            EndsWith:=vbNullString, _
                            BeginEndCompare:=vbTextCompare)
    If FoundCells Is Nothing Then
        Debug.Print "Value Not Found"
    Else
        For Each FoundCell In FoundCells
            FoundCell.Interior.Color = XlRgbColor.rgbLightGreen
        Next FoundCell
    End If

End Sub

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

Function FindAll(SearchRange As Range, _
                FindWhat As Variant, _
               Optional LookIn As XlFindLookIn = xlValues, _
                Optional LookAt As XlLookAt = xlWhole, _
                Optional SearchOrder As XlSearchOrder = xlByRows, _
                Optional MatchCase As Boolean = False, _
                Optional BeginsWith As String = vbNullString, _
                Optional EndsWith As String = vbNullString, _
                Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

If you want to use the cd or ls functions , you need proper identifiers before the function names ( % and ! respectively) use %cd and !ls to navigate

.

!ls    # to find the directory you're in ,
%cd ./samplefolder  #if you wanna go into a folder (say samplefolder)

or if you wanna go out of the current folder

%cd ../      

and then navigate to the required folder/file accordingly

If you have something like

Uncaught SyntaxError: embedded: Unexpected token

You probably missed a comma in a place like this:

  var CommentForm = React.createClass({
  getInitialState: function() {
      return {author: '', text: ''};

  }, // <---- DON'T FORGET THE COMMA

  render: function() {
      return (
      <form className="commentForm">
          <input type="text" placeholder="Nombre" />
          <input type="text" placeholder="Qué opina" />
          <input type="submit" value="Publicar" />
      </form>
      )
  }
  });

This is another way and is good to use with some text editors that are unable to correctly highlight every intricate code you create:

read -r -d '' str < <(cat somefile.txt)
echo "${#str}"
echo "$str"

Following are steps to kill server process:

1. lsof -i tcp:3000

2. kill -9 1234

where 1234 is the PID of process: localhost:3000 display in step 1.

OR

Remove file(server.pid) under Rails.root/tmp/pids/ and restart server.

OR

open app in another port by using command:

rails s -p 3001

Make sure you have your maven bin directory in the path and the JAVA_HOME property set

I had the same problem. I'm very new to iphone development and it was my first time trying to load my program onto my iphone. The message is correct, you need to create a certificate in the keychain. The best walkthrough is here:

http://developer.apple.com/ios/manage/overview/index.action

You of course need to have a developer account (need to have paid the $100 yearly fee).

I hope this helps.

Solution is just simple.

If you are trying to access server using your local IP address and you are getting error saying like Forbidden You don't have permission to access / on this server

Just open your httpd.conf file from (in my case C:/wamp/bin/apache/apache2.2.21/conf/httpd.conf)

Search for

<Directory "D:/wamp/www/"> .... ..... </Directory>

Replace Allow from 127.0.0.1

to

Allow from all

Save changes and restart your server.

Now you can access your server using your IP address

you can try something like this:

import java.io.*;
import java.util.*;
class FindFile 
{
    public void findFile(String name,File file)
    {
        File[] list = file.listFiles();
        if(list!=null)
        for (File fil : list)
        {
            if (fil.isDirectory())
            {
                findFile(name,fil);
            }
            else if (name.equalsIgnoreCase(fil.getName()))
            {
                System.out.println(fil.getParentFile());
            }
        }
    }
    public static void main(String[] args) 
    {
        FindFile ff = new FindFile();
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter the file to be searched.. " );
        String name = scan.next();
        System.out.println("Enter the directory where to search ");
        String directory = scan.next();
        ff.findFile(name,new File(directory));
    }
}

Here is the output:

J:\Java\misc\load>java FindFile
Enter the file to be searched..
FindFile.java
Enter the directory where to search
j:\java\
FindFile.java Found in->j:\java\misc\load

If you mean you want to fetch everything from the beginning up to a particular point, Charles Bailey's answer is perfect. If you want to do the reverse and retrieve a subset of the history going back from the current date, you can use git clone --depth [N] where N is the number of revs of history you want. However:

--depth

Create a shallow clone with a history truncated to the specified number of revisions. A shallow repository has a number of limitations (you cannot clone or fetch from it, nor push from nor into it), but is adequate if you are only interested in the recent history of a large project with a long history, and would want to send in fixes as patches.

I am having this issue as well. Here is the code that is getting inserted for the close button:

When I turn off the style="display:none:" on the button, then the close button appears. So for some reason that display:none; is getting set, and I don't see how to control that. So another way to address this might be to simply override the display:none. Don't see how to do that though.

I note that the answer posted by KyleMit does work, but makes a different looking X button.

I also note that this issue does not affect all dialogs on my pages, but just some of them. Some dialogs work as expected; other have no title (ie, the span containing the title is empty) while the close button is present.

I am thinking something is seriously wrong and it might not the time for 1.10.x.

But after further work, I discovered that in some cases the titles were not getting set properly, and after fixing that, the X close button reappeared as it should be.

I used to set the titles like this:

('#ui-dialog-title-ac-popup').text('Add Admin Comments for #' + $ac_userid);

That id does not exist in my code, but is created apparently by jquery from ac-popup and ui-dialog-title. Kind of a kludge. But as I said that no longer works, and I have to use the following instead:

$('.ui-dialog-title').text('Add Admin Comments for #' + $ac_userid);

After doing that, the missing button issue seems to be better, although I am not sure if they are definitely related.

It seems you can provide just the local image name, assuming it is in the same folder...

It suffices like:

background-image: url("img1.png")

Access the json array like you would any other array.

for(var i =0;i < itemData.length-1;i++)
{
  var item = itemData[i];
  alert(item.Test1 + item.Test2 + item.Test3);
}

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

If you want to

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

Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping settings icon then scroll down to developer options and tap it then you will see on the top right a on off switch select on and then tap ok, thats it you all done.

<th nowrap="nowrap">

or

<th style="white-space:nowrap;">

or

<th class="nowrap">
<style type="text/css">
.nowrap { white-space: nowrap; }
</style>

Go to the "Server" view, then double-click the Tomcat server you're running. The access log files are stored relative to the path in the "Server path" field, which itself is relative to the workspace path.

This worked for me in laravel 4.2

$id = User::insertGetId([
    'username' => Input::get('username'),
    'password' => Hash::make('password'),
    'active'   => 0
]);

Since you using standard HTML you will need to define separate class for and manual set the rows to the classes.

I do not know how to solve this using code, but I do manually adjust the control panel at the right bottom in the plot figure, and adjust the figure size like:

f, ax = plt.subplots(figsize=(16, 12))

at the meantime until you get a matched size colobar. This worked for me.

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

There are several ways to do this, shown below.

As a friendly warning, be careful and up-front to the user when dealing with account, profile, and contact data. If you misuse a user's email address or other personal information, bad things can happen.

Method A: Use AccountManager (API level 5+)

You can use AccountManager.getAccounts or AccountManager.getAccountsByType to get a list of all account names on the device. Fortunately, for certain account types (including com.google), the account names are email addresses. Example snippet below.

Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8+
Account[] accounts = AccountManager.get(context).getAccounts();
for (Account account : accounts) {
    if (emailPattern.matcher(account.name).matches()) {
        String possibleEmail = account.name;
        ...
    }
}

Note that this requires the GET_ACCOUNTS permission:

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

More on using AccountManager can be found at the Contact Manager sample code in the SDK.

Method B: Use ContactsContract.Profile (API level 14+)

As of Android 4.0 (Ice Cream Sandwich), you can get the user's email addresses by accessing their profile. Accessing the user profile is a bit heavyweight as it requires two permissions (more on that below), but email addresses are fairly sensitive pieces of data, so this is the price of admission.

Below is a full example that uses a CursorLoader to retrieve profile data rows containing email addresses.

public class ExampleActivity extends Activity implements LoaderManager.LoaderCallbacks<Cursor> {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getLoaderManager().initLoader(0, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle arguments) {
        return new CursorLoader(this,
                // Retrieve data rows for the device user's 'profile' contact.
                Uri.withAppendedPath(
                        ContactsContract.Profile.CONTENT_URI,
                        ContactsContract.Contacts.Data.CONTENT_DIRECTORY),
                ProfileQuery.PROJECTION,

                // Select only email addresses.
                ContactsContract.Contacts.Data.MIMETYPE + " = ?",
                new String[]{ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE},

                // Show primary email addresses first. Note that there won't be
                // a primary email address if the user hasn't specified one.
                ContactsContract.Contacts.Data.IS_PRIMARY + " DESC");
    }

    @Override
    public void onLoadFinished(Loader<Cursor> cursorLoader, Cursor cursor) {
        List<String> emails = new ArrayList<String>();
        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {
            emails.add(cursor.getString(ProfileQuery.ADDRESS));
            // Potentially filter on ProfileQuery.IS_PRIMARY
            cursor.moveToNext();
        }

        ...
    }

    @Override
    public void onLoaderReset(Loader<Cursor> cursorLoader) {
    }

    private interface ProfileQuery {
        String[] PROJECTION = {
                ContactsContract.CommonDataKinds.Email.ADDRESS,
                ContactsContract.CommonDataKinds.Email.IS_PRIMARY,
        };

        int ADDRESS = 0;
        int IS_PRIMARY = 1;
    }
}

This requires both the READ_PROFILE and READ_CONTACTS permissions:

<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />

I would suggest:

DECLARE @sqlStatement nvarchar(MAX),
        @tableName nvarchar(50) = 'TripEvent',
        @columnName nvarchar(50) = 'CreatedDate';

SELECT                  @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
        FROM            sys.default_constraints AS dc
            LEFT JOIN   sys.columns AS sc
                ON      (dc.parent_column_id = sc.column_id)
        WHERE           dc.parent_object_id = OBJECT_ID(@tableName)
        AND         type_desc = 'DEFAULT_CONSTRAINT'
        AND         sc.name = @columnName
PRINT'   ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+';  '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement

The code compiles ok for me. May be you have forgotten to add the import:

import android.app.AlertDialog;

Anyway, you have a good tutorial here.

You can also do:

tree | grep filename

This pipes the output of the tree command to grep for a search. This will only tell you whether the file exists though.

Also check out Darek Mihocka's Emulators.com for great advice on instruction-level optimization for JITs, and many other goodies on building efficient emulators.

Relaxing your requirement to work on IE6 and legacy browsers you can use ::before and display: inline-block

div
{
  display: inline-block;
  position: relative;    
}
div::before
{
  content: "";
  display: block;
  position: absolute;
  z-index: -1;
  width: 100%;
  height: 100%;
  background:red;
  opacity: .2;
}

Demo at http://jsfiddle.net/KVyFH/172/ ?

It will work on any modern browser

You can use window.location.pathname.split('/');

That will produce an array with all of the items between the /'s

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

I'd recommend using the Buffer class:

var someEncodedString = Buffer.from('someString', 'utf-8');

This avoids any unnecessary dependencies that other answers require, since Buffer is included with node.js, and is already defined in the global scope.

It must be a configuration problem. Your pom is fine.

Here's what I did. New folder, put your pom inside. Then in eclipse: import -> maven -> existing maven project. Dependencies got included in the project.

I did this using eclipse helios. I think the plugin version I am using is 0.12

You should check the maven properties in eclipse.

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

This will return the first element

set.iterator().next();

StringBuffer is mutable. It can change in terms of length and content. StringBuffers are thread-safe, meaning that they have synchronized methods to control access so that only one thread can access a StringBuffer object's synchronized code at a time. Thus, StringBuffer objects are generally safe to use in a multi-threaded environment where multiple threads may be trying to access the same StringBuffer object at the same time.

StringBuilder The StringBuilder class is very similar to StringBuffer, except that its access is not synchronized so that it is not thread-safe. By not being synchronized, the performance of StringBuilder can be better than StringBuffer. Thus, if you are working in a single-threaded environment, using StringBuilder instead of StringBuffer may result in increased performance. This is also true of other situations such as a StringBuilder local variable (ie, a variable within a method) where only one thread will be accessing a StringBuilder object.

Swift 3 & 4

Set the supportedInterfaceOrientations property of specific UIViewControllers like this:

class MyViewController: UIViewController {

    var orientations = UIInterfaceOrientationMask.portrait //or what orientation you want
    override var supportedInterfaceOrientations : UIInterfaceOrientationMask {
    get { return self.orientations }
    set { self.orientations = newValue }
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    //...
}

UPDATE

This solution only works when your viewController is not embedded in UINavigationController, because the orientation inherits from parent viewController.
For this case, you can create a subclass of UINavigationViewController and set these properties on it.

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

Very odd but I used the IP address (vs the hostname) and it worked for me.

I solve this problem by always using the [h] option on floats (such as figures) so that they (mostly) go where I place them. Then when I look at the final draft, I adjust the location of the float by moving it in the LaTeX source. Usually that means moving it around the paragraph where it is referenced. Sometimes I need to add a page break at an appropriate spot.

I've found that the default placement of floats is reasonable in LaTeX, but manual adjustments are almost always needed to get things like this just right. (And sometimes it isn't possible for everything to be perfect when there are lots of floats and footnotes.)

The manual for the memoir class has some good information about how LaTeX places floats and some advice for manipulating the algorithm.

Validate the INPUT.

$time = strtotime($_POST['dateFrom']);
if ($time) {
  $new_date = date('Y-m-d', $time);
  echo $new_date;
} else {
   echo 'Invalid Date: ' . $_POST['dateFrom'];
  // fix it.
}

Use Convert.ToInt32 from mscorlib as in

decimal value = 3.14m;
int n = Convert.ToInt32(value);

See MSDN. You can also use Decimal.ToInt32. Again, see MSDN. Finally, you can do a direct cast as in

decimal value = 3.14m;
int n = (int) value;

which uses the explicit cast operator. See MSDN.

Here is how to get the value of all checked checkboxes as an array:

var values = (function() {
                var a = [];
                $(".checkboxes:checked").each(function() {
                    a.push(this.value);
                });
                return a;
            })()

Well, this is probably frowned upon but you can make a 1px transparent image, then size it as needed in between text.

Some text <img src="spacer.png" height="1px" width="10px"> Some more text

I've run into this issue when one or two spaces just wasn't enough for my design sensibilities.

change max_connections variable in postgresql.conf file located in /var/lib/pgsql/data or /usr/local/pgsql/data/

The admin and manager apps are two separate things. Here's a snapshot of a tomcat-users.xml file that works, try this:

<?xml version='1.0' encoding='utf-8'?>  
<tomcat-users>  
    <role rolename="tomcat"/>  
    <role rolename="role1"/>  
    <role rolename="manager"/>  
    <user username="tomcat" password="tomcat" roles="tomcat"/>  
    <user username="both" password="tomcat" roles="tomcat,role1"/>  
    <user username="role1" password="tomcat" roles="role1"/>  
    <user username="USERNAME" password="PASSWORD" roles="manager,tomcat,role1"/>  
</tomcat-users>  

It works for me very well

I had the same problem on a staging server. I had no issues running rake tasks on my local development machine, but deploying to the staging server failed with the "Could not find a JavaScript runtime" error message while trying to run the assets:precompile rake task.

Of course, therubyracer and execjs were in my Gemfile, and I was using the latest versions. My Gemfile.lock files matched, and I further verified versions by running bundle show.

After searching around on Google, I ended up deleting all of my gems and reinstalling them which fixed the problem. I still don't know what the root cause was, but maybe this will help you.

Here's what my environment looks like, BTW:

Ubuntu 10.04.3 LTS
rbenv
Ruby 1.9.2-p290
bundler-1.0.21
execjs-1.3.0
therubyracer-0.9.9

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

in my case this is the solution to fix it. When you create a project select MinGW GCC from the Toolchains panel.

Once the project is created, select project file, press ctrl + b to build the project. Then hit run and the the output should be printed on the console.

You separate multiple program arguments with spaces. (this was not obvious to me)

Program arguments:Julia 52 Actress

I had this concern when working on a Rails application with Docker.

My most preferred approach is to generally not use quotes. This includes not using quotes for:

• variables like ${RAILS_ENV}
• values separated by a colon (:) like postgres-log:/var/log/postgresql
• other strings values

I, however, use double-quotes for integer values that need to be converted to strings like:

• docker-compose version like version: "3.8"
• port numbers like "8080:8080"

However, for special cases like booleans, floats, integers, and other cases, where using double-quotes for the entry values could be interpreted as strings, please do not use double-quotes.

Here's a sample docker-compose.yml file to explain this concept:

version: "3"

services:
  traefik:
    image: traefik:v2.2.1
    command:
      - --api.insecure=true # Don't do that in production
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

That's all.

I hope this helps

I have tried this and it is working fine for me:

sqlcmd -S servername -E -s~ -W -k1 -Q  "sql query here" > "\\file_path\file_name.csv"

I recently created a library for creating Gson objects fluently:

http://jglue.org/fluent-json/

It works like this:

  JsonObject jsonObject = JsonBuilderFactory.buildObject() //Create a new builder for an object
  .addNull("nullKey")                            //1. Add a null to the object

  .add("stringKey", "Hello")                     //2. Add a string to the object
  .add("stringNullKey", (String) null)           //3. Add a null string to the object

  .add("numberKey", 2)                           //4. Add a number to the object
  .add("numberNullKey", (Float) null)            //5. Add a null number to the object

  .add("booleanKey", true)                       //6. Add a boolean to the object
  .add("booleanNullKey", (Boolean) null)         //7. Add a null boolean to the object

  .add("characterKey", 'c')                      //8. Add a character to the object
  .add("characterNullKey", (Character) null)     //9. Add a null character to the object

  .addObject("objKey")                           //10. Add a nested object
    .add("nestedPropertyKey", 4)                 //11. Add a nested property to the nested object
    .end()                                       //12. End nested object and return to the parent builder

  .addArray("arrayKey")                          //13. Add an array to the object
    .addObject()                                 //14. Add a nested object to the array
      .end()                                     //15. End the nested object
    .add("arrayElement")                         //16. Add a string to the array
    .end()                                       //17. End the array

    .getJson();                                  //Get the JsonObject

String json = jsonObject.toString();

And through the magic of generics it generates compile errors if you try to add an element to an array with a property key or an element to an object without a property name:

JsonObject jsonArray = JsonBuilderFactory.buildArray().addObject().end().add("foo", "bar").getJson(); //Error: tried to add a string with property key to array.
JsonObject jsonObject = JsonBuilderFactory.buildObject().addArray().end().add("foo").getJson(); //Error: tried to add a string without property key to an object.
JsonArray jsonArray = JsonBuilderFactory.buildObject().addArray("foo").getJson(); //Error: tried to assign an object to an array.
JsonObject jsonObject = JsonBuilderFactory.buildArray().addObject().getJson(); //Error: tried to assign an object to an array.

Lastly there is mapping support in the API which allows you to map your domain objects to JSON. The goal being when Java8 is released you'll be able to do something like this:

Collection<User> users = ...;
JsonArray jsonArray = JsonBuilderFactory.buildArray(users, { u-> buildObject()
                                                                 .add("userName", u.getName())
                                                                 .add("ageInYears", u.getAge()) })
                                                                 .getJson();

In case of Allow IP to mysql server linux machine. you can do following command--

 nano /etc/httpd/conf.d/phpMyAdmin.conf  and add Desired IP.

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8
   Order allow,deny
   allow from all
   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>

    Require ip 192.168.9.1(Desired IP)

</RequireAny>
   </IfModule>
 <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     #Allow from All

     Allow from 192.168.9.1(Desired IP)

</IfModule>

And after Update, please restart using following command--

sudo systemctl restart httpd.service

I can think of 2 ways to achieve this:

• IFNULL():

  The IFNULL() function returns a specified value if the expression is NULL.If the expression is NOT NULL, this function returns the expression.

Syntax:

IFNULL(expression, alt_value)

Example of IFNULL() with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND IFNULL( price, 0 ) > ( SELECT AVG( IFNULL( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) g
                                    WHERE cume_dist < 0.50
                                  )
        AND IFNULL( price, 0 ) < ( SELECT AVG( IFNULL( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) d
                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

• COALESCE()

  The COALESCE() function returns the first non-null value in a list.

Syntax:

COALESCE(val1, val2, ...., val_n)

Example of COALESCE() with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan

Try

git checkout <commit hash>
git checkout -b new_branch

The commit should only exist once in your tree, not in two separate branches.

This allows you to check out that specific commit and name it what you will.

print my_string[0:100]

are there any cases where it doesn't work?

Just to throw this in the mix, if you are developing on a local server, it might not work. You need to specify a scheme, otherwise the browser may assume that src="//cdn.example.com/js_file.js" is src="file://cdn.example.com/js_file.js", which will break since you're not hosting this resource locally.

Microsoft Internet Explorer seem to be particularly sensitive to this, see this question: Not able to load jQuery in Internet Explorer on localhost (WAMP)

You would probably always try to find a solution that works on all your environments with the least amount of modifications needed.

The solution used by HTML5Boilerplate is to have a fallback when the resource is not loaded correctly, but that only works if you incorporate a check:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<!-- If jQuery is not defined, something went wrong and we'll load the local file -->
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.10.2.min.js"><\/script>')</script>

UPDATE: HTML5Boilerplate now uses <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js after deciding to deprecate protocol relative URLs, see [here][3].

Try to use this solution:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome

Run regedit, Delete the key, then restart Chrome.

There are several answers. i ended up with a similar yet different solution that makes sense to me, maybe it will make sense to you as well. My main objective was to be able to pass logs to handlers by their level (debug level logs to the console, warnings and above to files):

from flask import Flask
import logging
from logging.handlers import RotatingFileHandler

app = Flask(__name__)

# make default logger output everything to the console
logging.basicConfig(level=logging.DEBUG)

rotating_file_handler = RotatingFileHandler(filename="logs.log")
rotating_file_handler.setLevel(logging.INFO)

app.logger.addHandler(rotating_file_handler)

created a nice util file named logger.py:

import logging

def get_logger(name):
    return logging.getLogger("flask.app." + name)

the flask.app is a hardcoded value in flask. the application logger is always starting with flask.app as its the module's name.

now, in each module, i'm able to use it in the following mode:

from logger import get_logger
logger = get_logger(__name__)

logger.info("new log")

This will create a new log for "app.flask.MODULE_NAME" with minimum effort.

The result of summing two Int16 variables is an Int32:

Int16 i1 = 1;
Int16 i2 = 2;
var result = i1 + i2;
Console.WriteLine(result.GetType().Name);

It outputs Int32.

In Python 3, you can use the builtin range function like this

>>> list(range(9))
[0, 1, 2, 3, 4, 5, 6, 7, 8]

Note 1: Python 3.x's range function, returns a range object. If you want a list you need to explicitly convert that to a list, with the list function like I have shown in the answer.

Note 2: We pass number 9 to range function because, range function will generate numbers till the given number but not including the number. So, we give the actual number + 1.

Note 3: There is a small difference in functionality of range in Python 2 and 3. You can read more about that in this answer.

Tail the log as a background job (&) and it will interleave with rspec output.

tail -f log/test.log &
bundle exec rspec

We can combine multiple conditions together to reduce the performance overhead.

Let there are three variables a b c on which we want to perform cases. We can do this as below:

CASE WHEN a = 1 AND b = 1 AND c = 1 THEN '1'
     WHEN a = 0 AND b = 0 AND c = 1 THEN '0'
ELSE '0' END,

Add #pragma comment(lib, "Your library name here") to your source.

Wrapper[] data = gson.fromJson(jElement, Wrapper[].class);

One practical reason to choose one over the other is if you're going to use the result in another environment, for example JavaScript.

In PHP urlencode('test 1') returns 'test+1' while rawurlencode('test 1') returns 'test%201' as result.

But if you need to "decode" this in JavaScript using decodeURI() function then decodeURI("test+1") will give you "test+1" while decodeURI("test%201") will give you "test 1" as result.

In other words the space (" ") encoded by urlencode to plus ("+") in PHP will not be properly decoded by decodeURI in JavaScript.

In such cases the rawurlencode PHP function should be used.

There's always the HTML5 download attribute :

This attribute, if present, indicates that the author intends the hyperlink to be used for downloading a resource so that when the user clicks on the link they will be prompted to save it as a local file.

If the attribute has a value, the value will be used as the pre-filled file name in the Save prompt that opens when the user clicks on the link.

var A = [['n','sqrt(n)']];

for(var j=1; j<10; ++j){ 
    A.push([j, Math.sqrt(j)]);
}

var csvRows = [];

for(var i=0, l=A.length; i<l; ++i){
    csvRows.push(A[i].join(','));
}

var csvString = csvRows.join("%0A");
var a         = document.createElement('a');
a.href        = 'data:attachment/csv,' +  encodeURIComponent(csvString);
a.target      = '_blank';
a.download    = 'myFile.csv';

document.body.appendChild(a);
a.click();

FIDDLE

Tested in Chrome and Firefox, works fine in the newest versions (as of July 2013).
Works in Opera as well, but does not set the filename (as of July 2013).
Does not seem to work in IE9 (big suprise) (as of July 2013).

An overview over what browsers support the download attribute can be found Here
For non-supporting browsers, one has to set the appropriate headers on the serverside.

Apparently there is a hack for IE10 and IE11, which doesn't support the download attribute (Edge does however).

var A = [['n','sqrt(n)']];

for(var j=1; j<10; ++j){ 
    A.push([j, Math.sqrt(j)]);
}

var csvRows = [];

for(var i=0, l=A.length; i<l; ++i){
    csvRows.push(A[i].join(','));
}

var csvString = csvRows.join("%0A");

if (window.navigator.msSaveOrOpenBlob) {
    var blob = new Blob([csvString]);
    window.navigator.msSaveOrOpenBlob(blob, 'myFile.csv');
} else {
    var a         = document.createElement('a');
    a.href        = 'data:attachment/csv,' +  encodeURIComponent(csvString);
    a.target      = '_blank';
    a.download    = 'myFile.csv';
    document.body.appendChild(a);
    a.click();
}

For me, problem was Typo in location path.

Maybe first thing to check out for this kind of problem

Is path to project.

Collections is a utility class, meaning that it defines a set of methods that perform common, often re-used functions, such as sorting a list, rotating a list, finding the minimum value etc. And these common methods are defined under static scope.

Collection is an interface that is implemented by AbstractCollection which in turn is implemented by AbstractList, AbstractSet etc.

Also, Collections class has thirty-two convenience implementations of its collection interfaces, providing unmodifiable collections, synchronized collections. Nearly all of these implementations are exported via static factory methods in one noninstantiable class (java.util.Collections).

Reference: Effective Java

To use session variables, it's necessary to start the session by using the session_start function, this will allow you to store your data in the global variable $_SESSION in a productive way.

so your code will finally look like this :

<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>

<?php 
 
 // starting the session
 session_start();


 if (isset($_POST['Submit'])) { 
 $_SESSION['picturenum'] = $_POST['picturenum'];
 } 
?> 

<strong><?php echo $_SESSION['picturenum'];?></strong>

to make it easy to use and to avoid forgetting it again, you can create a session_file.php which you will want to be included in all your codes and will start the session for you:

session_start.php

 <?php
   session_start();
 ?> 

and then include it wherever you like :

<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>

<?php 
 
 // including the session file
 require_once("session_start.php");


 if (isset($_POST['Submit'])) { 
 $_SESSION['picturenum'] = $_POST['picturenum'];
 } 
?> 

that way it is more portable and easy to maintain in the future.

other remarks

• if you are using Apache version 2 or newer, be careful. instead of
  <?
  to open php's tags, use <?php, otherwise your code will not be interpreted

• variables names in php are case-sensitive, instead of write $_session, write $_SESSION in capital letters

good work!

One liner:

def dot(m1, m2):
    return [
        [sum(x * y for x, y in zip(m1_r, m2_c)) for m2_c in zip(*m2)] for m1_r in m1
    ]

Explanation:

zip(*m2) - gets a column from the second matrix

zip(m1_r, m2_c) - creates tuple from m1 row and m2 column

sum(...) - sums multiplication row * col

Test:

m1 = [[1, 2, 3], [4, 5, 6]]
m2 = [[7, 8], [9, 10], [11, 12]]
result = dot(m1, m2)
assert result == [[58, 64], [139, 154]]

A list of the few remaining cosmetic and packaging differences between Oracle JDK 11 and OpenJDK 11 can be found in this blog post:

https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

In short:

• Oracle JDK 11 emits a warning when using the -XX:+UnlockCommercialFeatures option,
• it can be configured to provide usage log data to the “Advanced Management Console” tool,
• it has always required third party cryptographic providers to be signed by a known certificate,
• it will continue to include installers, branding and JRE packaging,
• while the javac --release command behaves slightly differently for the Java 9 and Java 10 targets, and
• the output of the java --version and java -fullversion commands will distinguish Oracle JDK builds from OpenJDK builds.

The most common case I've seen for seemingly mysterious ArrayIndexOutOfBoundsExceptions, i.e. apparently not caused by your own array handling code, is the concurrent use of SimpleDateFormat. Particularly in a servlet or controller:

public class MyController {
  SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");

  public void handleRequest(ServletRequest req, ServletResponse res) {
    Date date = dateFormat.parse(req.getParameter("date"));
  }
}

If two threads enter the SimplateDateFormat.parse() method together you will likely see an ArrayIndexOutOfBoundsException. Note the synchronization section of the class javadoc for SimpleDateFormat.

Make sure there is no place in your code that are accessing thread unsafe classes like SimpleDateFormat in a concurrent manner like in a servlet or controller. Check all instance variables of your servlets and controllers for likely suspects.

Appending a single scalar could be done a bit easier as already shown (and also without converting to float) by expanding the scalar to a python-list-type:

import numpy as np
a = np.array([[1,3,4],[1,2,3],[1,2,1]])
x = 10

b = np.hstack ((a, [[x]] * len (a) ))

returns b as:

array([[ 1,  3,  4, 10],
       [ 1,  2,  3, 10],
       [ 1,  2,  1, 10]])

Appending a row could be done by:

c = np.vstack ((a, [x] * len (a[0]) ))

returns c as:

array([[ 1,  3,  4],
       [ 1,  2,  3],
       [ 1,  2,  1],
       [10, 10, 10]])

Swift Version --> Remove the object from your data array before you call

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        print("Deleted")

        currentCart.remove(at: indexPath.row) //Remove element from your array 
        self.tableView.deleteRows(at: [indexPath], with: .automatic)
    }
}

Use the parameter named as validate_certs to ignore the ssh validation

- ec2_ami:
    instance_id: i-0661fa8b45a7531a7
    wait: yes
    name: ansible
    validate_certs: false
    tags:
      Name: ansible
      Service: TestService

By doing this it ignores the ssh validation process

I know this has an acceptable answer, but I ran into a situation where clientWidth didn't work, as iPhone (at least mine) returned 980, not 320, so I used window.screen.width. I was working on existing site, being made "responsive" and needed to force larger browsers to use a different meta-viewport.

Hope this helps someone, it may not be perfect, but it works in my testing on iOs and Android.

//sweet hack to set meta viewport for desktop sites squeezing down to mobile that are big and have a fixed width 
  //first see if they have window.screen.width avail
  (function() {
    if (window.screen.width)
    {
      var setViewport = {
        //smaller devices
        phone: 'width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no',
        //bigger ones, be sure to set width to the needed and likely hardcoded width of your site at large breakpoints  
        other: 'width=1045,user-scalable=yes',
        //current browser width
        widthDevice: window.screen.width,
        //your css breakpoint for mobile, etc. non-mobile first
        widthMin: 560,
        //add the tag based on above vars and environment 
        setMeta: function () {
          var params = (this.widthDevice <= this.widthMin) ? this.phone : this.other; 
          var head = document.getElementsByTagName("head")[0];
          var viewport = document.createElement('meta');
          viewport.setAttribute('name','viewport');
          viewport.setAttribute('content',params);
          head.appendChild(viewport);
        }
      }
      //call it 
      setViewport.setMeta();
    }
  }).call(this);

Just because @MartinCapodici 's comment is awesome I write here as an answer to give visibility.

All clockwise:

• WPF start West (left->top->right->bottom)
• Netscape (ie CSS) start North (top->right->bottom->left)

Just use .only before 'describe', 'it' or 'context'. I run using "$npm run test:unit", and it executes only units with .only.

describe.only('get success', function() {
 // ...
});

it.only('should return 1', function() {
  // ...
});

The most upvoted answer can be improved.

Let me refer to GNU Make manual "Setting variables" and "Flavors", and add some comments.

Recursively expanded variables

The value you specify is installed verbatim; if it contains references to other variables, these references are expanded whenever this variable is substituted (in the course of expanding some other string). When this happens, it is called recursive expansion.

foo = $(bar)

The catch: foo will be expanded to the value of $(bar) each time foo is evaluated, possibly resulting in different values. Surely you cannot call it "lazy"! This can surprise you if executed on midnight:

# This variable is haunted!
WHEN = $(shell date -I)

something:
    touch $(WHEN).flag

# If this is executed on 00:00:00:000, $(WHEN) will have a different value!
something-else-later: something
    test -f $(WHEN).flag || echo "Boo!"

Simply expanded variable

VARIABLE := value
VARIABLE ::= value

Variables defined with ‘:=’ or ‘::=’ are simply expanded variables.

Simply expanded variables are defined by lines using ‘:=’ or ‘::=’ [...]. Both forms are equivalent in GNU make; however only the ‘::=’ form is described by the POSIX standard [...] 2012.

The value of a simply expanded variable is scanned once and for all, expanding any references to other variables and functions, when the variable is defined.

Not much to add. It's evaluated immediately, including recursive expansion of, well, recursively expanded variables.

The catch: If VARIABLE refers to ANOTHER_VARIABLE:

VARIABLE := $(ANOTHER_VARIABLE)-yohoho

and ANOTHER_VARIABLE is not defined before this assignment, ANOTHER_VARIABLE will expand to an empty value.

Assign if not set

FOO ?= bar

is equivalent to

ifeq ($(origin FOO), undefined)
FOO = bar
endif

where $(origin FOO) equals to undefined only if the variable was not set at all.

The catch: if FOO was set to an empty string, either in makefiles, shell environment, or command line overrides, it will not be assigned bar.

Appending

VAR += bar

Appending:

When the variable in question has not been defined before, ‘+=’ acts just like normal ‘=’: it defines a recursively-expanded variable. However, when there is a previous definition, exactly what ‘+=’ does depends on what flavor of variable you defined originally.

So, this will print foo bar:

VAR = foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

but this will print foo:

VAR := foo
# ... a mile of code
VAR += $(BAR)
BAR = bar
$(info $(VAR))

The catch is that += behaves differently depending on what type of variable VAR was assigned before.

Multiline values

The syntax to assign multiline value to a variable is:

define VAR_NAME :=
line
line
endef

or

define VAR_NAME =
line
line
endef

Assignment operator can be omitted, then it creates a recursively-expanded variable.

define VAR_NAME
line
line
endef

The last newline before endef is removed.

Bonus: the shell assignment operator ‘!=’

 HASH != printf '\043'

is the same as

HASH := $(shell printf '\043')

Don't use it. $(shell) call is more readable, and the usage of both in a makefiles is highly discouraged. At least, $(shell) follows Joel's advice and makes wrong code look obviously wrong.

As others have said startsWith and endsWith are part of ES6 and not available in IE11. Our company always uses lodash library as a polyfill solution for IE11. https://lodash.com/docs/4.17.4

_.startsWith([string=''], [target], [position=0])

if the map is short you can do:

ImmutableMap.of(key, value, key2, value2); // ...up to five k-v pairs

If it is longer then:

ImmutableMap.builder()
   .put(key, value)
   .put(key2, value2)
   // ...
   .build();

There are 3 main possibilities to execute a function:

var callback = function(x, y) {
    // "this" may be different depending how you call the function
    alert(this);
};

1. callback(argument_1, argument_2);
2. callback.call(some_object, argument_1, argument_2);
3. callback.apply(some_object, [argument_1, argument_2]);

The method you choose depends whether:

1. You have the arguments stored in an Array or as distinct variables.
2. You want to call that function in the context of some object. In this case, using the "this" keyword in that callback would reference the object passed as argument in call() or apply(). If you don't want to pass the object context, use null or undefined. In the latter case the global object would be used for "this".

Docs for Function.call, Function.apply

If you're working with "real" data for which the grid intervals and sequence cannot be guaranteed to be increasing or unique (hopefully the (x,y,z) combinations are unique at least, even if these triples are duplicated), I would recommend the akima package for interpolating from an irregular grid to a regular one.

Using your definition of data:

library(akima)
im <- with(data,interp(x,y,z))
with(im,image(x,y,z))

And this should work not only with image but similar functions as well.

Note that the default grid to which your data is mapped to by akima::interp is defined by 40 equal intervals spanning the range of x and y values:

> formals(akima::interp)[c("xo","yo")]
$xo
seq(min(x), max(x), length = 40)

$yo
seq(min(y), max(y), length = 40)

But of course, this can be overridden by passing arguments xo and yo to akima::interp.

I would approach it like this:

sizes = [100, 250] print "How much space should the random song list occupy?" print '\n'.join("{0}. {1}Mb".format(n, s)                 for n, s in enumerate(sizes, 1)) # present choices choice = int(raw_input("Enter choice:")) # throws error if not int size = sizes[0] # safe starting choice if choice in range(2, len(sizes) + 1):     size = sizes[choice - 1] # note index offset from choice print "You  want to create a random song list that is {0}Mb.".format(size) 

You could also loop until you get an acceptable answer and cover yourself in case of error:

choice = 0 while choice not in range(1, len(sizes) + 1): # loop     try: # guard against error         choice = int(raw_input(...))     except ValueError: # couldn't make an int         print "Please enter a number"         choice = 0 size = sizes[choice - 1] # now definitely valid 

You can do like this

sqlcmd -S <server Name> -U sa -P sapassword -i inputquery_file_name -o outputfile_name

From your command prompt run sqlcmd /? to get all the options you can use with sqlcmd utility

Not too hard to explain... This is like typing hello worl, hitting the left-arrow key twice, typing d, and hitting the down-arrow key.

At least, that is how I infer your terminal is interpeting the \b and \n codes.

Redirect the output to a file and I bet you get something else entirely. Although you may have to look at the file's bytes to see the difference.

[edit]

To elaborate a bit, this printf emits a sequence of bytes: hello worl^H^Hd^J, where ^H is ASCII character #8 and ^J is ASCII character #10. What you see on your screen depends on how your terminal interprets those control codes.

Hibernate is not going to make it easy for you to do what you are trying to do. From the Hibernate documentation:

Note that when using referencedColumnName to a non primary key column, the associated class has to be Serializable. Also note that the referencedColumnName to a non primary key column has to be mapped to a property having a single column (other cases might not work). (emphasis added)

So if you are unwilling to make AnEmbeddableObject the Identifier for Bar then Hibernate is not going to lazily, automatically retrieve Bar for you. You can, of course, still use HQL to write queries that join on AnEmbeddableObject, but you lose automatic fetching and life cycle maintenance if you insist on using a multi-column non-primary key for Bar.

It look's as if you forgot to activate you virtual environment try running python3 -m venv venv or if you already have virtual environment set up try to activate it by running source venv/bin/activate

You can use hex colors:

your_contorl.Color = DirectCast(ColorConverter.ConvertFromString("#D8E0A627"), Color)
